"Vertex shares with us the vision that VX-950 could represent a significant step forward in treating the growing number of patients with hepatitis C in the coming years," said Joseph Scodari, Worldwide Chairman, Pharmaceuticals Group of Johnson & Johnson. "This agreement further reinforces our established strong commitment to finding innovative treatments for global viral diseases."

Terms of the Agreement
Under the terms of the agreement, Janssen receives exclusive rights to commercialize VX-950 in Europe, South America, the Middle East, Africa and Australia. Vertex will receive an upfront payment of $165 million upon signing the contract. In addition, Vertex could receive up to $380 million based on successful development and launch of VX-950 in the territories. The agreement also includes a royalty on product sales in Europe and other territories outside of North America and the Far East. Vertex will continue to lead the global development plan for VX-950.

Vertex and Tibotec also announced today that the companies will establish a global health initiative to increase the prevention, diagnosis, treatment and cure of HCV infection to be principally directed toward developing countries.

Key Financial Terms:

• Upfront and milestones: Vertex expects to receive a total of $545 million in payments, including an upfront payment of $165 million upon signing the contract, and a further $380 million in additional contingent milestone payments based on the successful development and approval of VX-950, and launch in the regions where Janssen Pharmaceutica has commercial rights.
• Royalties: a tiered royalty averaging a mid-20 percent range of net sales in Janssen's regions and contingent upon successful commercialization. In addition, Janssen will be responsible for certain third party royalties in its regions.
• Drug development costs: reimbursement of 50 percent of drug development costs incurred by Vertex.
• Commercial supply responsibilities: Vertex and Janssen will be responsible for drug supply in their respective territories.

Mitsubishi Pharma holds development and commercial rights to VX-950 in Japan and certain Far East countries, and is expected to commence clinical development in its territories in the second half of 2006.

About VX-950
VX-950 is an investigational oral inhibitor of hepatitis C virus protease, an enzyme essential for viral replication, and is one of the most advanced investigational agents that specifically targets HCV. In clinical studies to date, researchers have observed rapid and dramatic antiviral activity with VX-950. In clinical studies of VX-950 to date, no patients have discontinued treatment and no serious adverse events have been reported.

In May 2006, Vertex announced the details of a global Phase 2 program for VX-950 consisting of three large clinical studies that are expected to enroll approximately 1000 patients with HCV at clinical centers in the United States and Europe. Vertex initiated the U.S.-based PROVE 1 study in May. The PROVE 2 study is being initiated in Europe.

About Hepatitis C
Hepatitis C is a liver disease caused by the infection by hepatitis C virus (HCV), which is found in the blood of people with the disease. HCV, a serious public health concern affecting 170 million people worldwide, is spread through direct contact with the blood of an infected person. Though many people with hepatitis C may not experience symptoms, others may have symptoms such as jaundice, abdominal pain, fatigue and fever. Hepatitis C significantly increases a person's risk of developing chronic liver disease, cirrhosis, liver cancer and death. The burden of liver disease associated with HCV infection is increasing, and current therapies only provide sustained benefit in about 50% of patients with genotype 1 HCV, the most common strain of the virus. Specifically targeted antiviral therapies for HCV in clinical development may have the potential to increase the proportion of patients in who the virus can be eradicated.

Safe Harbor Statement
This press release contains "forward-looking statements" as defined in the Private Securities Litigation Reform Act of 1995. Such forward-looking statements, include the statement that VX-950 could represent a significant step forward in treating the growing number of patients with hepatitis C in the coming years; that Tibotec and Janssen will contribute important capabilities and resources that will strengthen Vertex's global clinical, regulatory and commercial execution for the VX-950 program; and that upon successful development, approval and launch of VX-950 in the regions where Janssen has commercial rights, Vertex could receive up to $380 million based on successful development and launch of VX-950 in the territories, and could receive tiered royalties in the mid-20 percent range. These statements are based on current expectations of future events. If underlying assumptions prove inaccurate or unknown risks or uncertainties materialize, actual results could vary materially from Vertex's and Johnson & Johnson 's expectations and projections. Risks and uncertainties include general industry conditions and competition; economic conditions, such as interest rate and currency exchange rate fluctuations; technological advances and patents attained by competitors; challenges inherent in new product development, including obtaining regulatory approvals; domestic and foreign health care reforms and governmental laws and regulations; and trends toward health care cost containment. These risks and uncertainties also include the risks that clinical trials for VX-950 may not proceed as planned due to technical, scientific, or patient enrollment issues, or disagreements with regulatory authorities over trial design or other matters; that the scale and scope of future clinical and nonclinical studies may change and will be determined in significant part by data collected in ongoing and future trials; that further clinical studies of VX-950 may not reflect the results obtained in early clinical and nonclinical studies; that ongoing nonclinical studies, including toxicology studies, will yield currently unanticipated negative outcomes that could adversely affect planned clinical trials; that results from the Vertex's clinical trials commenced during 2006 will be insufficient to support a Phase III program without additional trials and consequent delay in the timetable for potential approval; and that any potential product may not achieve sales in Janssen's territory sufficient to earn the royalties referenced above. A further list and description of these risks, uncertainties and other factors can be found in the section entitled "Risk Factors" in Vertex's Annual Report on Form 10-K for the fiscal year ended December 31, 2005 and in Exhibit 99 of Johnson & Johnson's Annual Report on Form 10-K for the fiscal year ended January 1, 2006. Copies of these Form 10-K filings, as well as subsequent filings, are available online at www.sec.gov or on request from the Vertex or Johnson & Johnson. Neither Vertex nor Johnson & Johnson assumes any obligation to update any forward-looking statements as a result of new information or future events or developments.
