These interim Consolidated Financial Statements of the Company have not been audited by independent public accountants. However, in the opinion of management, all adjustments required for a fair presentation of the financial position of the Company as of December 31, 1997, and the results of its operations for the nine-months ended December 31, 1996 and 1997, and its cash flows for the nine-months ended December 31, 1996 and 1997, have been made. The results of operations for these interim periods are not necessarily indicative of the operating results for the full year. (2) Commitments and Contingencies- On July 31, 1997, the Company and its marketing partner Mallinckrodt Inc., ("Mallinckrodt") filed suit (the "MBI Case") in United States District Court for the District of Columbia against four potential competitors - Sonus Pharmaceuticals, Inc ("Sonus"), Nycomed Imaging AS ("Nycomed"), ImaRx Pharmaceutical Corp. ("ImaRx") and its marketing partner DuPont Merck Pharmaceutical Corp. ("DuPont Merck"), and Bracco International BV ("Bracco") - seeking declarations that certain of their ultrasound contrast agent patents are invalid. On the same day, the Company and Mallinckrodt filed counterclaims in cases filed against the FDA by Bracco, Sonus, ImaRx and DuPont Merck in which the Company had intervened as a defendant seeking the same relief as in the MBI Case. The court subsequently dismissed these counterclaims following the FDA's reclassification ruling (as previously reported), and resulting mootness of the proceedings against the FDA. The complaint filed by the Company and Mallinckrodt in the MBI Case alleges that each of the defendants' patents is invalid on a variety of independent grounds under U.S. patent law. In addition to requesting that all of the patents in question be declared invalid, the complaint requests a declaration that, contrary to defendants' contentions, the Company and Mallinckrodt do not infringe the defendants' patents, and asks that defendants be enjoined from proceeding against the Company and Mallinckrodt for infringement until the status of defendants' patents has been determined by the court or the U.S. Patent and Trademark Office ("PTO"). The complaint alleges that each defendant has claimed or is likely to claim that its patent or patents cover OPTISON(TM), the Company's second-generation ultrasound contrast agent, and will attempt to prevent its commercialization. All of the defendants except Nycomed filed motions to dismiss the complaint on jurisdictional grounds. On January 5, 1998, the court hearing the MBI Case dismissed each of the defendants except Nycomed, ruling that the court lacked jurisdiction over those defendants with respect to the Company's claims of patent invalidity and noninfringement. The court's ruling does not purport to rule on the merits of the Company's claims; the dismissal was based solely on jurisdictional grounds. Following Sonus's dismissal as a defendant in the MBI Case, Sonus activated the patent infringement lawsuit ("Sonus Case") which it had filed in August 1997 against the Company and Mallinckrodt in the United States District Court for the Western District of Washington. Sonus's complaint alleges that the manufacture and sale of OPTISON(TM) by the Company and Mallinckrodt infringe two patents owned by Sonus. These patents are the same patents which are currently in reexamination at the PTO (as described in the next paragraph), and are the same patents for which the Company was seeking a declaration of invalidity in the MBI Case. Although the complaint was filed in August 1997, Sonus had agreed not to proceed with the Sonus Case until the jurisdictional motions were decided in the MBI Case. Beginning in July 1997, the Company received the first of five notices from the PTO granting the Company's petitions for reexamination which it had filed with respect to five patents held by three potential competitors, Sonus, Nycomed and ImaRx. Each of the five notices stated there was a substantial new question of patentability raised by the Company's petitions with respect to all claims of the patents. Each of the patents currently in the reexamination process is related to the use of perfluorocarbon gases in ultrasound contrast agents and is included among the patents for which the Company was seeking a declaration of invalidity in the MBI Case (and for which the Company is continuing to seek a declaration of invalidity in the case of Nycomed's patents). In November and December 1997, the PTO issued office actions in connection with the Company's patent reexamination petitions filed against Sonus and Nycomed, respectively. The PTO office actions reject all relevant claims of the patents owned by Sonus and Nycomed involved in the MBI Case and the Sonus Case, based on prior art not previously disclosed to the PTO by Sonus and Nycomed during prosecution of their patent applications. If maintained through further proceedings before the patent examiner and on any appeal, the PTO rejections will invalidate the patents which Sonus and Nycomed are attempting to assert against the Company and Mallinckrodt to block the manufacture and sale of OPTISON(TM). Litigation or administrative proceedings relating to these matters could result in a substantial cost to the Company; and given the complexity of the legal and factual issues, the inherent vicissitudes and uncertainty of litigation, and other factors, there can be no assurance of a favorable outcome. An unfavorable outcome could have a material adverse effect on the Company's business, financial condition and results of operations. Moreover, there can be no assurance that, in the event of an unfavorable outcome, the Company would be able to obtain a license to any proprietary rights that may be necessary to commercialize OPTISON(TM), either on acceptable terms or at all. If the Company were required to obtain a license necessary to commercialize OPTISON(TM), the Company's failure or inability to do so would have a material adverse effect on the Company's business, financial condition and results of operations. (3) Earnings per Share - In December 1997, the Company adopted Statement of Financial Accounting Standards No. 128, "Earnings Per Share" (SFAS 128). The statement specifies the computation, presentation, and disclosure requirements for earnings per share (EPS). The adoption of this statement had no material impact to the Company due to its capital structure, which consists solely of one class of stock. PART I- FINANCIAL INFORMATION Item 2 - MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS The following management discussion and analysis should be read in conjunction with (1) the current Consolidated Financial Statements and (2) the Company's Consolidated Financial Statements and related Notes and Management's Discussion and Analysis of Financial Condition and Results of Operations in its Annual Report on Form 10-K for the year ended March 31, 1997. From time to time, the Company may publish forward-looking statements relating to such matters as anticipated financial performance, business prospects, technological developments, new products, regulatory approval, research and development activities and similar matters. A variety of factors could cause the Company's actual results and experience to differ materially from the Company's anticipated results or other expectations. The risks and uncertainties that may affect the operations, performance, development and results of the Company's business include the expense and uncertain outcome of the litigation described under the caption "Recent Events," including the possibility of injunctive relief to competitors prohibiting the sale of OPTISON(TM); a ruling by the Patent and Trademark Office ("PTO") in the pending patent reexamination proceedings favoring competitors' patents; delays or an inability to bring OPTISON(TM) to market in Europe as a result of regulatory delays or patent litigation; difficulties and delays with respect to the performance of clinical trials; delays by regulatory authorities in approving additional indications for OPTISON(TM), including the evaluation of myocardial perfusion; manufacturing problems; difficulties and delays with respect to marketing and sales activities; general uncertainties accompanying the development and introduction of new products; and other risk factors reported from time to time in the Company's reports filed with the Securities and Exchange Commission. Recent Events On December 31, 1997, the Company's new drug application for OPTISON(TM), the Company's second-generation contrast agent for cardiac ultrasound imaging, was approved by the United States Food and Drug Administration (the FDA). This approval permits the marketing of OPTISON(TM) in the United States for use in patients with suboptimal echocardiagrams to opacify the left ventricle and to improve the delineation of the left ventricular endocardial borders. OPTISON(TM), the first of the perfluorocarbon containing ultrasound agents to reach the market, enables physicians to enhance resolution of anatomical structure where ultrasound alone is inadequate. Ultrasound cardiac imaging has several advantages over other imaging methods. It is minimally invasive, relatively inexpensive and can quickly provide a real-time image. OPTISON(TM) helps increase the effectiveness of echocardiography in diagnosing heart disease by introducing gas-filled microspheres into the blood. The microspheres travel in the blood stream to the left ventricle of the heart where the microspheres reflect the soundwaves generated from ultrasound equipment, enabling the development of a clearer, more descriptive ultrasound image. On January 27, 1998, the European Union's Committee for Proprietary Medicinal Products ("CPMP") of the European Medicines Evaluation Agency (EMEA) recommended the approval of OPTISON(TM). The regulatory file was submitted to the EMEA under the centralized procedure in which a single license is granted for the 15 member states of the European Union. The marketing authorization is expected to be granted by the European Commission within several months. Upon EMEA approval, OPTISON(TM) will be sold by Mallinckrodt, Inc. ("Mallinckrodt"). On July 31, 1997, the Company and its marketing partner Mallinckrodt filed suit (the "MBI Case") in United States District Court for the District of Columbia against four potential competitors - Sonus Pharmaceuticals, Inc ("Sonus"), Nycomed Imaging AS ("Nycomed"), ImaRx Pharmaceutical Corp. ("ImaRx") and its marketing partner DuPont Merck Pharmaceutical Corp. ("DuPont Merck"), and Bracco International BV ("Bracco") seeking declarations that certain of their ultrasound contrast agent patents are invalid. On the same day, the Company and Mallinckrodt filed counterclaims in cases filed against the FDA by Bracco, Sonus, ImaRx and DuPont Merck in which the Company had intervened as a defendant seeking the same relief as in the MBI Case.

Sonus's complaint alleges that the manufacture and sale of OPTISON(TM) by the Company and Mallinckrodt infringe two patents owned by Sonus. These patents are the same patents which are currently in reexamination at the PTO (as described in the next paragraph), and are the same patents for which the Company was seeking a declaration of invalidity in the MBI Case.

Litigation or administrative proceedings relating to these matters could result in a substantial cost to the Company; and given the complexity of the legal and factual issues, the inherent vicissitudes and uncertainty of litigation, and other factors, there can be no assurance of a favorable outcome. An unfavorable outcome could have a material adverse effect on the Company's business, financial condition and results of operations. Moreover, there can be no assurance that, in the event of an unfavorable outcome, the Company would be able to obtain a license to any proprietary rights that may be necessary to commercialize OPTISON(TM), either on acceptable terms or at all. If the Company were required to obtain a license necessary to commercialize OPTISON(TM), the Company's failure or inability to do so would have a material adverse effect on the Company's business, financial condition and results of operations. Liquidity and Capital Resources At December 31, 1997, the Company had net working capital of $27.2 million compared to $43.8 million at March 31, 1997. Cash, cash equivalents, marketable securities and certificates of deposit pledged were $28.7 million at December 31, 1997 compared to $44.4 million at March 31, 1997. In June 1997, the Company entered into an equipment leasing agreement with Mellon US Leasing ("Mellon") for a lease line of $1.6 million with a term of 48 months. For the next several years, the Company expects to incur substantial additional expenditures associated with product development. The Company anticipates that its existing resources, including the proceeds of the public offering in May 1996 and interest thereon, plus payments under its collaborative agreement with Mallinckrodt, will enable the Company to fund its operations for at least the next twelve months. The Company continually reviews its product development activities in an effort to allocate its resources to those products that the Company believes have the greatest commercial potential. Factors considered by the Company in determining the products to pursue may include, but are not limited to, the projected markets, potential for regulatory approval, technical feasibility and estimated costs to bring the product to the market. Based upon these factors, the Company may from time to time reallocate its resources among its product development activities. The Company may pursue a number of options to raise additional funds, including borrowings; lease arrangements; collaborative research and development arrangements with pharmaceutical companies; the licensing of product rights to third parties; or additional public and private financing, as capital requirements change as a result of strategic, competitive, technological and regulatory factors. There can be no assurance that funds from these sources will be available on favorable terms, or at all. Results of Operations Revenues Under Collaborative Agreements. Revenues under collaborative agreements were $1.3 million and $3.8 million for the three-month and nine-month periods ended December 31, 1997 compared to $1.1 million and $3.3 million for the same periods in the prior year. These revenues in both years consist of quarterly payments to support clinical trials, regulatory submissions and product development received from Mallinckrodt under the Company's amended agreement with Mallinckrodt which the Company entered into in September 1995. Product and Royalty Revenues. Revenues from product sales and royalties were $123,000 and $428,000 for the three-month and nine-month periods ended December 31, 1997, compared to $216,000 and $426,000 for the same periods in the prior year. Product revenues result from the Company's sales of ALBUNEX(R) to Mallinckrodt which are recognized upon shipment of the product. The transfer price for the Company's sales is determined under the Company's agreement with Mallinckrodt and is equal to 40% of Mallinckrodt's net sales price to its end users of the product. Royalty revenues were received under a licensing agreement between the Company and Abbott Laboratories for the Company's patented in vitro diagnostic DNA probe technology. Costs of Products Sold. Cost of products sold totaled $1.5 million and $3.9 million for the three-month and nine-month periods ended December 31, 1997, resulting in a negative gross profit margin. This negative gross profit margin was due to the fact that the current low levels of production are insufficient to cover the Company's fixed manufacturing overhead expenses. For the same periods in the prior year, cost of products sold totaled $1.1 million and $3.7 million. The Company anticipates an increase in its gross profit margins if and when ALBUNEX(R) sales volume increases and if and when OPTISON(TM) obtains market acceptance. The increase in sales volume would permit the fixed costs included in manufacturing overhead to be allocated over a larger number of vials produced. Manufacturing fixed costs are currently running at an annual rate of approximately $5 million. The amount of any increase in the Company's margins and the time required by the Company to achieve higher margins are highly dependent on market acceptance of ALBUNEX(R) and OPTISON(TM) and are therefore uncertain. Research and Development Costs. For the three-month and nine-month periods ended December 31, 1997, the Company's research and development costs totaled $2.9 million and $7.8 million, as compared to $2.4 million and $7.3 million for the same periods in 1996. This increase is due to the fact that the Company has initiated clinical trials for additional indications for OPTISON(TM). Selling, General and Administrative Expenses. For the three-month and nine-month periods ended December 31, 1997, the Company's selling, general and administrative expenses totaled $3.1 million and $8.9 million, compared to $1.9 million and $5.4 million for the same periods in 1996. This increase in the current year is primarily attributable to increased legal expenses. See the discussion under "Recent Events". Interest Expense and Interest Income. Interest expense for the three-month and nine-month periods ended December 31, 1997 amounted to $176,000 and $553,000, and consisted of mortgage interest on the Company's manufacturing building and interest on a note payable which is secured by the tangible assets of the Company. The interest rate on the mortgage was 8% in December 1997. The note payable, in the amount of $6 million, bears interest at prime plus 1% and is payable in monthly installments of principal plus interest over five years. The interest rate on the note was 9.5% in December 1997. The decrease in interest income in the current year is due primarily to lower average cash and marketable securities balances. The Company's cash is invested primarily in short-term, fixed principal investments, such as U.S. Government agency issues, corporate bonds, certificates of deposit and commercial paper. Prospective Information On December 31, 1997, the Company's new drug application for OPTISON(TM), the Company's second-generation contrast agent for cardiac ultrasound imaging, was approved by the United States FDA. This approval permits the marketing of OPTISON(TM) in the United Sates for use in patients with suboptimal echocardiagrams to opacify the left ventricle and to improve the delineation of the left ventricular endocardial borders. OPTISON(TM), the first of the perfluorocarbon containing ultrasound agents to reach the market, enables physicians to enhance resolution of anatomical structure where ultrasound alone is inadequate. Ultrasound cardiac imaging has several advantages over other imaging methods. It is minimally invasive, relatively inexpensive and can quickly provide a real-time image.

The microspheres travel in the blood stream to the left ventricle of the heart where the microspheres reflect the soundwaves generated from ultrasound equipment, enabling the development of a clearer, more descriptive ultrasound image. On January 27, 1998, the European Union's CPMP of the EMEA recommended the approval of OPTISON(TM). The regulatory file was submitted to the EMEA under the centralized procedure in which a single license is granted for the 15 member states of the European Union. The marketing authorization is expected to be granted by the European Commission within several months. Upon EMEA approval, OPTISON(TM) will be sold by Mallinckrodt. The Company is involved in several legal and administrative proceedings which could result in a substantial cost to the Company. Given the complexity of the legal and factual issues and the uncertainty of litigation, there can be no assurance of a favorable outcome. An unfavorable outcome could have a material adverse effect on the Company's business, financial condition and results of operations. For a detailed discussion of these matters, see "Recent Events".
