Vertex Pharmaceuticals to Present at the Merrill Lynch Global Pharmaceutical, Biotechnology and Medical Device Conference

Cambridge, MA, February 3, 2004 -- Vertex Pharmaceuticals Incorporated (Nasdaq: VRTX) will review its 2004 outlook and provide its 2004 financial guidance at the Merrill Lynch Global Pharmaceutical, Biotechnology and Medical Device Conference in New York today, Tuesday, February 3, 2004. The update will be presented by Joshua Boger, Ph.D., Chairman and CEO of Vertex Pharmaceuticals. A live audio webcast of the presentation will be available on Vertex's website, www.vrtx.com, at 4:10 pm ET, February 3, 2004. An archived audio webcast of the presentation will be available on Vertex's website through February 16, 2004.

"In 2004, Vertex expects to make important advances with our antiviral and inflammation product portfolio," stated Dr. Boger. "In particular, we believe that our drug candidates in development targeting HCV, merimepodib and VX-950, represent significant medical and commercial opportunities. We believe that focused investment in our proprietary drug candidates in 2004, combined with our pharmaceutical partners' investment in Vertex's products, will position the Company for significant long-term value creation and commercial success."

Dr. Boger continued, "In addition to investing in our clinical activities, we also will continue to cultivate the creative and innovative work being done in our discovery organization. In 2004, we anticipate advancing novel preclinical drug candidates from our ion channel and kinase research programs. Importantly, our amended kinase collaboration with Novartis will provide us with an earlier opportunity to achieve clinical milestones and also will provide us with flexibility to dedicate development resources to our proprietary drug candidates."

2004 Corporate Goals:
Vertex's milestones for 2004 were established to enable the Company to advance its business toward its objective of sustained value creation. Specifically, Vertex expects to:

• Advance HIV franchise with partner GlaxoSmithKline
  • Launch the new HIV protease inhibitor Lexiva(TM) in Europe.
  • Begin Phase II development of investigational HIV protease inhibitor VX-385.
• Advance proprietary HCV pipeline
  • Initiate advanced clinical development of oral HCV therapy merimepodib in combination with ribavirin and pegylated interferon.
  • Initiate Phase I development of oral HCV protease inhibitor VX-950 in healthy volunteers in 1H ‘04; initiate clinical evaluation of VX-950 in HCV patients in 2H '04.
  • Advance second-generation HCV compounds into preclinical development.
• Advance inflammation pipeline
  • Complete pilot Phase II trial of p38 MAP kinase inhibitor VX-702 for acute coronary syndromes (ACS).
  • Initiate Phase II development of oral ICE inhibitor VX-765.
  • Complete toxicology evaluation for pralnacasan in partnership with Aventis.
• Invest in discovery organization
  • Select new preclinical drug candidates in kinase and voltage-gated sodium ion channel research programs.
• Establish new pharmaceutical collaborations targeting the following areas:
  • Vertex proprietary compounds targeting HCV and inflammatory disease (merimepodib, VX-950, VX-765): Establish collaborations to support development and commercialization outside of North America.
  • Vertex proprietary compounds in selected therapeutic areas (VX-944, VX-702): Establish collaborations to support development and commercialization in worldwide markets.
  • Vertex discovery organization: Establish collaborations to support ion channel, GPCR and bacterial gyrase programs.

Full Year 2004 Financial Guidance
This section contains forward-looking guidance about the financial outlook for Vertex Pharmaceuticals. At today's conference, Vertex will provide financial guidance for 2004 on a basis that excludes any charges and gains. The Company also will reiterate its guidance for a full-year 2003 loss of less than $180 million, before any charges and gains. In 2003, Vertex engaged in activities that resulted in gains on the sale of PanVera LLC and Aurora Instruments, as well as charges related to operational restructuring and lease restructuring. The charge associated with the estimated costs of lease restructuring may be updated quarterly, until the restructuring of the lease is completed.

"Vertex is focused on executing our business strategy, which is to bring Vertex-discovered drugs to the market both independently and with partners," stated Ian Smith, Senior Vice President and Chief Financial Officer of Vertex Pharmaceuticals. "Maintaining our financial strength is a key component of this strategy. We are confident that our financial guidance for 2004, which was based on an evaluation of our business objectives, and our strategy for achieving those objectives, will pave the way to our ultimate objective of profitability and sustained profit growth."

• Loss: Vertex expects that the full year 2004 loss will be in the range of $140 to $150 million, before any gains or charges, specifically, completion of a lease restructuring.
• Revenues: Total revenue will be in the range of $90 to $100 million in 2004. This will be comprised of $60 to $65 million in committed funding and milestones from existing collaborative partners, and $15 to $18 million from HIV product royalties. In addition, the Company is currently in discussions with pharmaceutical companies regarding strategic research and productdevelopment agreements, and the successful conclusion of such discussions may result in additional revenue and cash flow in 2004.
• Research and Development (R&D) Expense: As Vertex prioritizes its investment toward proprietary drug candidates and realizes the benefits from an operational restructuring during 2003 in drug discovery, the Company projects that R&D costs will be in the range of $190 to $205 million for the full year of 2004.
• Sales, General and Administrative (SG&A) Expense: Vertex expects SG&A to be in the range of $38 to $43 million in 2004.
• Cash, Cash Equivalents, and Available for Sale Securities: Vertex expects cash, cash equivalents and available for sale securities to be in excess of $350 million at the end of 2004.
• Shares Outstanding: Vertex expects to have approximately 79 million weighted average shares outstanding at year-end 2004.

Mr. Smith continued, "In 2004, we are focused on reducing our loss by increasing revenue from multiple sources: funding from existing collaborative partners, by achieving milestones under our revised collaboration with Novartis and our GSK HIV collaboration; and from increased royalties from Lexiva, as we benefit from a successful worldwide product launch. In addition, we have focused our development investment toward compounds targeting HCV and inflammatory disease, and will gain the financial benefit in our discovery organization from an operational restructuring that occurred in 2003."

Non-GAAP Financial Measures
In this press release, Vertex's financial results are provided both in accordance with generally accepted accounting principles (GAAP) in the United States and using certain non-GAAP financial measures. In particular, Vertex provides guidance for a 2003 and 2004 loss, excluding any charges or gains, which are non-GAAP financial measures. These results are provided as a complement to results provided in accordance with GAAP because management believes these non-GAAP financial measures help indicate underlying trends in the Company's business, and uses these non-GAAP financial measures to establish budgets and operational goals that are communicated internally and externally, to manage the Company's business and to evaluate its performance.
