The merged company will focus on the 2004 launch of FACTIVE® (gemifloxacin mesylate tablets), which received FDA approval for two indications this year, the Ramoplanin clinical development program and the maturation of the companies' earlier stage assets. The combined company will keep the name Genome Therapeutics, and continue to trade on the Nasdaq National Market under the ticker "GENE" until a new name for the company is selected. A conference call with senior management from both companies is scheduled for today at 8:30 AM ET (details below).

Revenues from the launch of FACTIVE®, an orally administered, broad-spectrum fluoroquinolone antibiotic, will drive the merged company's near-term growth as a biopharmaceutical company. FACTIVE® currently has FDA marketing approval for the treatment of community-acquired pneumonia of mild to moderate severity (CAP)(a) and acute bacterial exacerbations of chronic bronchitis (ABECB)(b). FACTIVE® is expected to be launched during the summer of 2004. Strengthened by a robust pipeline led by Ramoplanin, which is in development for the prevention, treatment and control of serious hospital-based infections, the merged companies' product development and managerial synergies position the new company as a leader in the anti-infectives market.

"Merging with Genesoft is a transforming event for our company, as we will immediately realize our goal of becoming a biopharmaceutical company with a high-profile product and a complementary near-term product candidate in late-stage clinical trials," stated Steven M. Rauscher, Chairman and CEO of Genome Therapeutics, who will serve as President and CEO of the new company. "Initially, we will be focusing our efforts on ensuring the successful launch of FACTIVE® to coincide with next year's respiratory tract infections season, thus positioning the company as a key participant in the commercialization of anti-infective therapeutics."

"The increase in bacterial resistance to numerous antibiotic classes is quickly becoming a serious concern for physicians, who are recognizing the need to use the most potent antibiotic as first-line treatment in order to stem this growing problem," said Gary Patou, M.D., President of Genesoft. "Increasingly, physicians are realizing that their prescribing decisions can not only affect the individual patient receiving a drug, but also can have a larger societal impact. FACTIVE®, a unique fluoroquinolone, and Ramoplanin, a first-in-class antibiotic, could help address this challenge."

Product Portfolio

FACTIVE® has FDA approval for two indications: community-acquired pneumonia of mild to moderate severity(a) (including cases caused by multi-drug resistant Streptococcus pneumoniae) and acute bacterial exacerbations of chronic bronchitis(b). A regulatory filing for a third indication of FACTIVE® for acute bacterial sinusitis is planned. In addition, an intravenous form of the antibiotic is currently under development. Supplementing the FACTIVE® development pipeline are two novel anti-infectives: Ramoplanin, currently in Phase III and Phase II trials for the prevention and treatment of serious hospital-based infections, and a series of oral PDF (peptide deformylase) inhibitors, expected to enter Phase I testing in the future for treating respiratory tract infections. Genome Therapeutics also brings seven partnered programs to the merger through strategic alliances with pharmaceutical companies including Wyeth, Schering-Plough, Amgen and AstraZeneca.

"We are committed to building a premiere anti-infectives company, which will introduce products that satisfy the medical community's intensifying need for new therapeutic options," stated David B. Singer, Founder, Chairman and CEO of Genesoft Pharmaceuticals, who will assume the role of Chairman of the new company. "This merger supports our efforts to successfully launch FACTIVE®, as the management team at Genome Therapeutics possesses proven expertise in marketing antibiotics into the community and hospital settings. Our shareholders will also participate in the success of the integrated company's extensive portfolio of anti-infective opportunities."

This merger agreement has been unanimously approved by the Board of Directors at both Genome Therapeutics and Genesoft Pharmaceuticals.

FACTIVE® (gemifloxacin mesylate tablets) is an orally administered, broad-spectrum fluoroquinolone antibiotic to which Genesoft has licensed, from LG Life Sciences, all North American and European rights for commercialization. FACTIVE® was approved by the FDA for sale in the United States in April 2003. FACTIVE® is approved for the treatment of community-acquired pneumonia of mild to moderate severity(a) and for treating acute bacterial exacerbations of chronic bronchitis(b).

FACTIVE® should only be used to treat infections that are proven or strongly suspected to be caused by bacteria. It does not treat viral infections. The most common side effects include diarrhea, rash, nausea and headache. Rash is generally mild to moderate in nature, and more likely to occur if taken for longer than the recommended course. In addition, the safety and effectiveness of FACTIVE in children, adolescents, pregnant women, and lactating women have not been established. Gemifloxacin may prolong the QT interval in some patients and should be avoided in patients with a history of prolongation of the QTc interval, patients with uncorrected electrolyte disorders, and patients receiving class 1A or class III antiarrhythmic agents. For complete prescribing information, please see package insert.

(a) Caused by Streptococcus pneumoniae (including multi-drug resistant strains), Haemophilus influenzae, Moraxella catarrhalis, Mycoplasma pneumoniae, Chlamydia pneumoniae or Klebsiella pneumoniae. (b) Caused by Streptococcus pneumoniae, Haemophilus influenzae, Haemophilus parainfluenzae or Moraxella catarrhalis. About Ramoplanin

Genome Therapeutics' lead product candidate, Ramoplanin, is an investigational new drug in clinical development for the prevention, treatment and control of certain serious hospital-based infections. The company licensed the North American rights to Ramoplanin from Vicuron Pharmaceuticals. Ramoplanin has Fast Track status from the FDA and is currently in a Phase III clinical trial for the prevention of VRE bloodstream infections and in a Phase II study for treating Clostridium difficile-associated diarrhea (CDAD). Existing preclinical data suggest Ramoplanin has activity against several antibiotic-resistant, Gram-positive bacteria such as vancomycin-resistant enterococci (VRE), methicillin-resistant Staphylococcus aureus and vancomycin-resistant Staphylococcus aureus. The antibiotic has also been shown to be bactericidal in vitro against Clostridium difficile. In a Phase II study, Ramoplanin was shown to be highly effective at decolonizing patients carrying VRE in their gastrointestinal (GI) tracts. A pilot study is also underway examining Ramoplanin's potential role in controlling the spread of nosocomial bacteria.
