Oscient Pharmaceuticals Completes Acquisition of Cardiovascular Therapy ANTARA(R) 130mg (fenofibrate) Capsules

Commercialization by Oscient Sales Force to Primary Care Physicians Begins Later This Week

WALTHAM, Mass.--(HSMN NewsFeed)--Aug. 21, 2006--Oscient Pharmaceuticals (Nasdaq: OSCI ) has completed its acquisition of the U.S. rights to the cardiovascular product ANTARAŽ 130 mg (fenofibrate) capsules from Reliant Pharmaceuticals. ANTARA is part of the $22 billion U.S. market for treating dyslipidemias, which includes the $1 billion fenofibrate market. ANTARA will be commercialized by Oscient's national sales force beginning later this week.

"With the addition of ANTARA, we are executing a key part of our business strategy by acquiring a primary care product well-suited for commercialization by our sales team," stated Steven M. Rauscher, President and CEO. "The market for treating dyslipidemias continues to grow rapidly, with the fenofibrate segment of the market demonstrating average annual growth of 30% over the last three years. Combined with the continued success of our flagship antibiotic, FACTIVEŽ (gemifloxacin mesylate) tablets, ANTARA will further our growth as a commercial-stage biopharmaceutical company."

ANTARA is indicated as an adjunct treatment for hypercholesterolemia (high blood cholesterol) and hypertriglyceridemia (high triglycerides) in combination with diet. Clinical studies have shown that ANTARA along with a healthy diet is effective in reducing triglycerides and increasing HDL-C (high density lipoprotein-cholesterol) levels. In the 12 months ended June 2006, ANTARA generated approximately $35 million in revenue.

Oscient has made a payment of $78 million to Reliant for U.S. rights to ANTARA, plus a purchase of approximately $4 million in existing inventory. Oscient Pharmaceuticals has also finalized its agreement with Paul Capital Partners' Paul Royalty Fund II, LP (Paul Royalty) a leading, international healthcare investment fund, to provide $70 million of financing for this product acquisition.

Coincident with closing the acquisition and the financing, Gregory Brown, M.D., Partner, Paul Capital Partners, has joined the Company's Board of Directors. Dr. Brown's background includes over two decades of clinical, operating and healthcare investment experience. Previously, Dr. Brown worked at Adams, Harkness & Hill, where he served as the co-head of investment banking, and at Vector Securities International. Before receiving his business degree, Dr. Brown was a practicing thoracic and vascular surgeon. He earned his MBA from Harvard Business School, his MD from SUNY Upstate Medical Center, and his AB from Yale College.

"Greg shares our vision of growth for Oscient and when this opportunity arose, his enthusiasm for the product acquisition was instrumental in successfully executing the transaction," added Mr. Rauscher. "Recognized as one of the leaders in financing the growth of the biopharmaceutical industry, with his valuable Wall Street and medical experience, Greg will provide a unique perspective for our management team as we continue to build our Company."

J.P. Morgan Securities Inc. acted as financial advisor to Oscient Pharmaceuticals on this transaction.

Important Safety Information about ANTARA

ANTARA is indicated as adjunctive therapy to diet to reduce elevated LDL-C, total-C, triglycerides, and apo B, and to increase HDL-C in adult patients with primary hypercholesterolemia or mixed dyslipidemia (Fredrickson Types IIa and IIb). ANTARA is also indicated as adjunctive therapy to diet for treatment of adult patients with hypertriglyceridemia (Fredrickson Types IV and V hyperlipidemia). Lipid-altering agents should be used in addition to a diet restricted in saturated fat and cholesterol when response to diet and nonpharmacologic intervention alone has been inadequate.

Improving glycemic control in diabetic patients showing fasting chylomicronemia will usually reduce fasting triglycerides and eliminate chylomicronemia thereby obviating the need for pharmacologic intervention. Markedly elevated levels of serum triglycerides (e.g., >2,000 mg/dL) may increase the risk of developing pancreatitis. The effect of ANTARA therapy on reducing this risk has not been adequately studied.

ANTARA is contraindicated in patients with hypersensitivity to fenofibrate, in patients with hepatic or severe renal dysfunction including primary biliary cirrhosis, in patients with unexplained persistent liver function abnormality, and in patients with preexisting gallbladder disease. Fenofibrate has been associated with increases in serum transaminases. Regular periodic monitoring of liver function should be performed for duration of therapy, and therapy discontinued if enzyme levels persist above 3 times the normal limit. Fenofibrate may increase cholesterol excretion into the bile, leading to cholelithiasis. If cholelithiasis is suspected, ANTARA therapy should be discontinued. ANTARA may increase the effects of coumarin-type anticoagulants. Dosage adjustment based on frequent prothrombin time/INR determinations is advisable. Adverse events most frequently observed in clinical trials: abnormal liver function tests; respiratory disorder; abdominal pain; back pain; and headache.

ANTARA may occasionally be associated with pancreatitis, hypersensitivity reactions, and hematologic or skeletal muscle changes. Please see Full Prescribing Information available at

For example, our ability to increase our revenue and accelerate the time of our profitability following the ANTARA acquisition may be limited by: (i) our ability to successfully commercialize and market ANTARA or FACTIVE or to promote TESTIM due to: the limitations on our resources and experience in the commercialization of products; lack of acceptance by physicians, patients and third party payors; unanticipated safety, product liability, efficacy, or other regulatory issues; delays in recruiting and training sales personnel; problems relating to manufacturing or supply; inadequate distribution of the products by wholesalers, pharmacies, hospitals and other customers; and competition from other products; (ii) by our ability to integrate ANTARA into our business; (iii) whether we will be able to expand the indications for which FACTIVE is approved; (iv) the delay or inability to find sublicensing partners for FACTIVE or to negotiate favorable licensing terms; (v) the delay in or inability to obtain additional regulatory approvals of our products and product candidates due to negative, inconclusive or insufficient results in ongoing or future clinical trials, the FDA requiring additional information or data, delays in the progress of ongoing clinical trials, safety concerns arising with respect to our products or product candidates and disputes with the third parties from whom we license our products or product candidate; and (vi) delays by the FDA.
