                          NOTES TO FINANCIAL STATEMENTS
                                   (UNAUDITED)


1.    BASIS OF PRESENTATION

      The unaudited financial statements have been prepared in accordance with
generally accepted accounting principles for interim financial information and
with the instructions to Form 10-Q. Accordingly, they do not include all of the
information and footnotes required to be presented for complete financial
statements. The accompanying financial statements reflect all adjustments
(consisting only of normal recurring items) which are, in the opinion of
management, necessary for a fair presentation of the results for the interim
periods presented.

      The financial statements and related disclosures have been prepared with
the assumption that users of the interim financial information have read or have
access to the audited financial statements for the preceding fiscal year.
Accordingly, these financial statements should be read in conjunction with the
audited financial statements and the related notes thereto included in the Form
10-K for the year ended December 31, 1997 and filed with the SEC on March 31,
1998.

2.    RECENT ACCOUNTING PRONOUNCEMENTS

      In 1997, the Company adopted Statement of Financial Accounting Standards
No. 128, "Earnings Per Share ("EPS")" (SFAS 128). In accordance with this
statement, the Company has presented both basic and diluted EPS. Basic EPS is
based on the weighted average number of common shares outstanding. Diluted EPS
is based on the weighted average number of common shares and dilutive potential
common shares. Dilutive potential common shares are calculated under the
treasury stock method and consist of unexercised stock options and warrants.
Amounts previously reported have been restated to conform to the provisions of
SFAS 128.

      During 1997, the Financial Accounting Standards Board issued SFAS No. 130,
"Reporting Comprehensive Income." SFAS 130 requires unrealized gains or losses
on the Company's available-for-sale securities, which are currently reported in
shareholders' equity, to be included in other comprehensive income. SFAS 130 is
effective for financial statements for fiscal years beginning after December 15,
1997 and all interim periods thereafter. The total of other comprehensive income
for the periods ended June 30, 1998 and 1997 is immaterial.

      During 1997, the Financial Accounting Standards Board issued SFAS No. 131,
"Disclosures about Segments of an Enterprise and Related Information." SFAS No.
131 is effective for financial statements for fiscal years beginning after
December 15, 1997. The adoption of SFAS No. 131 is not expected to have a
material impact on the Company's results of operations, financial position or
disclosures.

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

OVERVIEW

      The Company is primarily engaged in the research, development and
commercialization of proprietary contrast agents for use in ultrasound imaging
and of proprietary drug delivery systems. The Company has financed its research
and development and clinical trials through payments received under agreements 
with its collaborative partners, private equity and debt financings, and an 
initial public offering ("IPO") completed in October 1995. Clinical trials of 
the Company's principal product under development, EchoGen(R) (perflenapent
injectable emulsion), began in January 1994. In 1996, the Company filed a New
Drug Application ("NDA") with the U.S. Food and Drug Administration ("FDA")for
EchoGen as well as a Marketing Authorization Application ("MAA") with the 
European Medicines Evaluation Agency ("EMEA").

      In February 1998, the Company received an action letter from the FDA which
indicated that the review of the EchoGen NDA was completed and the application
was considered inadequate for approval, citing certain deficiencies in the
application. The Company is in the process of preparing an amendment to the NDA
to address the deficiencies. Once the Company has filed the amendment with the
FDA, expected to be in the third quarter, the agency has up to 180 days to
review the amendment. Accordingly, once the FDA review is completed, the Company
expects that the agency will be in a position to issue another action letter.

      In March 1998, the Committee for Proprietary Medicinal Products ("CPMP")
issued a positive opinion on EchoGen for use as a transpulmonary
echocardiographic contrast agent in patients with suspected or established
cardiovascular disease who have had previous inconclusive non-contrast studies.
The CPMP is the scientific review committee of the EMEA and makes its
recommendations to the EMEA. On July 20, 1998, the EMEA ratified the CPMP
recommendation and granted a marketing authorization for EchoGen in the 15
countries of the European Union.

      In May 1996, the Company formed a strategic alliance with Abbott
Laboratories ("Abbott") for marketing and selling of ultrasound contrast agents,
including EchoGen, in the U.S. Under the agreement, Abbott agreed to pay the
Company certain clinical support and milestone payments, of which $23.0 million
has been paid as of June 30, 1998. In addition, Abbott purchased in May 1996,
for $4.0 million, warrants to acquire 500,000 shares of common stock of the
Company. The warrants are exercisable over five years at $16.00 per share. In
October 1996, the Company and Abbott entered into an agreement expanding
Abbott's territory to include Europe, Latin America, Canada, Middle East, Africa
and certain Asia/Pacific countries. Under the October 1996 agreement, Abbott has
agreed to pay the Company certain additional license and milestone payments, a
portion of which will be credited against future royalties once EchoGen is
approved for commercial sale. As of June 30, 1998, $9.9 million has been paid to
the Company by Abbott under the October 1996 agreement of which $4.9 million is
creditable against future royalties.

      The Company has granted Daiichi Pharmaceutical Co., Ltd. ("Daiichi"),
exclusive marketing and distribution rights to EchoGen in Japan and in certain
other countries in the Pacific Rim. As of June 30, 1998, Daiichi has paid the
Company option, license and milestone fees totaling $12.8 million.

      The Company's results of operations have varied and will continue to vary
significantly from quarter to quarter and depend on, among other factors, the
timing of milestone payments made by collaborative partners, the timing of
regulatory approvals, the entering into additional product license agreements by
the Company, and the timing and costs of the clinical trials conducted by the
Company. The Company's current collaborative partners can terminate their
agreements on short notice, and there can be no assurance that the Company will
receive any additional funding or milestone payments.

RESULTS OF OPERATIONS

      To date, the Company's reported revenues have been derived from payments
received under collaborative agreements with third parties. Revenue received
under collaborative agreements was $0.7 million for the second quarter of 1998
compared with $4.7 million for the same period of the prior year. For the six
months ended June 30, 1998, payments received under collaborative agreements
were $2.4 million compared to $9.8 million for the six months ended June 30,
1997.


                                       7
<PAGE>   8
      Research and development expenses were $2.2 million for the second quarter
of 1998 compared with $2.9 million for the second quarter of 1997. The decrease
was due primarily to the reimbursement by Abbott of approximately $0.6 million
of development costs associated with ongoing clinical trials for additional
indications for EchoGen. For the six months ended June 30, 1998, research and
development costs were $5.7 million compared to $5.5 million for the six months
ended June 30, 1997. The increase reflected the higher level of activity
supporting the regulatory approval process in the U.S. and Europe.

      General and administrative expenses were $1.8 million for the second
quarter of 1998 compared with $1.6 million in the prior year. For the first six
months of 1998, general and administrative costs were $3.5 compared to $2.8
million for the same period of the prior year. The increase for both the second
quarter and the first six months was primarily a result of the costs of filing,
prosecuting and protecting patents and, to a lesser extent, increases in
marketing and administrative personnel.

      The Company anticipates total operating expenses will increase in future
quarters due to ongoing and planned clinical trials to study additional
indications for EchoGen and future products and due to higher marketing and
administrative expenses as the Company continues to prepare for
commercialization of EchoGen. The Company may also incur significant expenses
relating to legal matters - see "Legal Proceedings." In addition, revenues in
future quarters will be primarily dependent upon the timing of certain
regulatory and commercialization milestones and associated payments under
collaborative agreements.

      Interest income, net of interest expense, was $96,000 and $436,000 for the
second quarter and first six months of 1998, respectively, compared to $242,000
and $460,000 for the same period of the prior year. The decrease was primarily
due to the lower levels of invested cash during these periods.

LIQUIDITY AND CAPITAL RESOURCES

      The Company has historically financed its operations with payments from
collaborative agreements, proceeds from equity financings and a bank line of
credit. At June 30, 1998, the Company had cash, cash equivalents and marketable
securities of $21.5 million, compared to $26.6 million at December 31, 1997. The
decrease was primarily due to the $6.4 million net loss reported in the first
six months of 1998 offset in part by $1.2 million of clinical development costs
reimbursed by Abbott.

      The Company has a bank loan agreement which provides for a $5.0 million
revolving line of credit facility and bears interest at the prime rate plus 1.0%
per annum. At June 30, 1998 there was $5.0 million outstanding under the line of
credit. The line of credit expires August 31, 1998 and is secured by the
tangible assets of the Company. The Company is required to maintain certain
minimum balances of cash and marketable securities in order to borrow under the
line of credit. There can be no assurance that the line of credit will be
renewed upon expiration.

      The Company expects that its cash needs will increase significantly in
future periods due to pending and planned clinical trials and higher
administrative and marketing expenses as the Company prepares for
commercialization of EchoGen. The Company estimates that existing cash and
marketable securities together with funds generated from operations, consisting
primarily of milestone payments, will be sufficient to meet operating
requirements through early 1999. The Company's future capital requirements will,
however, depend on many factors, including the ability of the Company to obtain
and retain continued funding from third parties under collaborative agreements,
the time and costs required to gain regulatory approvals, the progress of the
Company's research and development programs, clinical trials, the costs of
filing, prosecuting and enforcing patents, patent applications, patent claims
and trademarks, the costs of marketing and distribution, the status of competing
products and the market acceptance and third-party reimbursement of the
Company's products, if and when approved. If regulatory approvals are delayed,
or funding under collaborative agreements is delayed or reduced, the Company
will have to raise substantial additional equity or debt financing to complete
development of any product or to commercialize any products if and when approved
by the FDA. There can be no assurance that additional financing will be
available on acceptable terms, if at all.

YEAR 2000 COMPLIANCE

      During 1997 the Company completed a comprehensive review of software
applications used in critical business processes. The Company has determined
that all of its critical business systems are year 2000 compliant. There is no
guarantee that the systems of the Company's collaborative partners or
significant vendors will be year 2000 compliant; however, the Company will
continue to investigate the year 2000 compliance of collaborative partners or
significant vendors. If the Company's collaborative partners or significant
vendors are not year 2000 compliant, this could have an adverse effect on the
ability of collaborative partners or vendors to satisfy their obligations to the
Company or for the Company to electronically communicate with such parties.

FORWARD-LOOKING STATEMENTS

      This Report contains certain forward-looking statements within the meaning
of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the
Securities Exchange Act of 1934, as amended, and the Company intends that such
forward-looking statements be subject to the safe harbors created thereby.
Examples of these forward-looking statements include, but are not limited to,
(i) the progress and results of clinical trials, (ii) the submission of
applications for and the timing of marketing approvals, (iii) the anticipated
outcome or financial impact of litigation, (iv) the timing and amount of future
milestone payments, product revenues and expenses, and (v) the future uses of
capital and financial needs of the Company. While these statements made by the
Company are based on management's current beliefs and judgment, they are subject
to risks and uncertainties that could cause actual results to vary.

      In evaluating such statements, stockholders and investors should
specifically consider a number of factors and assumptions, including those
discussed in the text and the financial statements and their accompanying
footnotes in this Report and the risk factors detailed from time to time in the
Company's filings with the Securities and Exchange Commission. As discussed in
the Company's annual report on Form 10-K for the year ended December 31, 1997,
actual results could differ materially from those projected in the
forward-looking statements as a result of the following factors, among others:
uncertainty of governmental regulatory requirements; unproven safety and
efficacy; uncertainty of clinical trials; history of operating losses;
uncertainty of future financial results; uncertainty of market acceptance;
future capital requirements and uncertainty of additional funding; dependence on
third parties for funding, clinical development and distribution; dependence on
patents and proprietary rights; competition and risk of technological
obsolescence; limited manufacturing experience; dependence on limited contract
manufacturers and suppliers; lack of marketing and sales experience; and
limitations on third-party reimbursement.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

           On January 7, 1998, the Company announced that it had filed a patent
infringement action in the U.S. District Court in Seattle, Washington, against
Molecular Biosystems, Inc. ("MBI") and Mallinckrodt, Inc. The suit alleges that
one of MBI's ultrasound contrast agents infringes one or more of the Company's 
patents. MBI has filed counterclaims alleging that the patents asserted by 
SONUS are invalid and not infringed, and that SONUS has made false public 
statements and engaged in other actions intended to damage MBI and one of its
ultrasound contrast agents. A trial date has been set for this lawsuit in 
August 1999.

      In addition, the patents in this lawsuit are the subject of re-examination
by the U.S. Patent and Trademark Office. The outcome of the re-examination may
have a significant impact on the above identified patent infringement action.
Although the Patent and Trademark Office has issued a final rejection of the 
SONUS patents at issue, SONUS intends to take advantage of its right to respond 
to these rejections, and if necessary, appeal these rejections.
