ITEM 1. BUSINESS 

PART I 

Vertex is engaged in the discovery, development and commercialization of novel, small molecule pharmaceuticals for the treatment of 
diseases for which there are currently limited or no effective treatments. The Company is a leader in the use of structure-based drug 
design, an approach to drug discovery that integrates advanced biology, biophysics, chemistry, and information technologies in a 
coordinated and simultaneous fashion. The Company believes that this integrated approach is applicable to therapeutic targets in a 
broad range of diseases. Vertex's goal is to create a portfolio of highly specific, proprietary, small molecule drugs based on its 
knowledge of the atomic structure of proteins involved in the control of disease processes. 

Agenerase-TM- for the treatment of HIV infection and AIDS is the Company's first product to have a New Drug Application filed with 
the U.S. FDA for marketing approval. The Company's drug candidates currently in clinical trials include: 
- Two compounds, Incel-TM- in Phase II, and VX-853, in Phase I/II clinical studies for treatment of cancer multidrug resistance; - 
VX-497, an inhibitor of the enzyme IMPDH, currently in Phase II studies for the treatment of psoriasis and hepatitis C virus infection; 
- Timcodar dimesylate, a neurophilin ligand compound in a Phase II study for the treatment of diabetic neuropathy; - VX-740, an 
inhibitor of the enzyme ICE, that recently completed a Phase I clinical trial and may be useful in the treatment of inflammatory 
diseases; and 
- VX-745, an inhibitor of the enzyme p38 MAP kinase, currently in a Phase I clinical trial, that may be useful in the treatment of 
inflammatory and neurological diseases. 

In addition, the Company has research programs aimed at developing orally available small molecule compounds targeting 
neurodegenerative disorders and hepatitis C virus infection. 

STRUCTURE-BASED DRUG DESIGN 

Page 2 

Drugs are natural or synthetic compounds that interact with a target molecule, typically a protein, either to induce or to inhibit that 
molecule's function within the human body. Traditionally, pharmaceutical products have been discovered through screening thousands 
of compounds in predictive assays for a chosen disease target. Vertex uses an information-driven drug design approach that integrates 
multiple advanced technologies. 

Vertex's discovery programs have yielded clinical drug candidates in an average of 39 months from project initiation, two times faster 
than the industry average. Also, Vertex has at least one product candidate in clinical development from each of its first five research 
programs. In contrast, across the pharmaceutical industry an average of just 25% of all research projects result in a drug entering 
clinical trials. 

The drug discovery process is complex and involves multiple steps and disciplines. The key steps in the discovery and development of 
a compound for human testing (a drug candidate) typically include: 
- identification of a drug target; - development of a relevant biological assay; - selection of compounds for screening; - identification of 
a lead molecule; - optimization of the lead molecule; and - preclinical development. 

   2002.  EDGAR Online, Inc.

The Company's approach to structure-based design is an integrated approach combining efforts in biology, biophysics and chemistry in 
a coordinated and simultaneous fashion throughout the discovery process. This enables the Company to capture and apply information 
generated in one scientific discipline across an entire project. In addition, Vertex leverages the information base from its programs to 
capitalize on emerging therapeutic opportunities as they are discovered. 

Vertex integrates a number of core technologies as part of the Company's drug discovery platform. These include: 
- FUNCTIONAL GENOMICS. Vertex uses a number of functional genomics techniques, such as gene knock-out mice, to help guide 
target selection and test the potential of its compounds in disease models. 
- BIOPHYSICS. Vertex's crystallography group has solved more than a dozen structures and more than 200 target/inhibitor complexes 
in the past eight years. Vertex scientists have also pioneered innovative nuclear magnetic resonance (NMR) techniques, including the 
use of NMR for screening and a proprietary technology called NMR-SHAPES that can rapidly identify classes of compounds with 
appropriate binding properties. 
- CHEMISTRY. Vertex applies combinatorial chemistry techniques together with a strategy of parallel synthesis to explore the 
suitability and activity of a wide range of compounds. 
- COMPUTER-BASED MODELING. Vertex applies advanced, proprietary computational modeling tools to guide combinatorial and 
medicinal chemistry efforts in identifying and optimizing leads. 
- PHARMACOLOGY. At Vertex, pharmacological testing and pharmacokinetic and pharmacodynamic modeling are used early in the 
drug discovery process to improve the likelihood that compounds will possess desirable characteristics. 

Page 3 
The Company believes that its integrated structure-based approach to drug discovery and the applicability of this approach to a broad 
range of protein targets provides the Company with significant competitive advantages in the discovery and development of novel 
therapeutics for a variety of diseases. 

CORPORATE STRATEGY 

Vertex is concentrating on the discovery and development of drugs for the treatment of viral diseases, multidrug resistance in cancer, 
autoimmune diseases, inflammatory diseases and neurological diseases. The Company's research and development strategy is to 
identify therapeutic areas in which there is (i) an unmet clinical need, (ii) evidence that interaction with known protein targets will 
produce a therapeutic effect, and (iii) evidence that the protein targets will be appropriate for structural analysis using Vertex's 
scientific approach. 

The Company's business strategy is to develop some products independently and to form collaborations with pharmaceutical 
companies in other programs for which they can provide resources and access to competencies complementary to Vertex's in-house 
capabilities. Corporate collaborations with other pharmaceutical companies allow Vertex to share the inherent risks of drug 
development and allocate the Company's internal resources more effectively. The financial support, as well as the resources in 
development, marketing and sales, provided by corporate collaborators has allowed Vertex to focus on expanding its clinical and 
discovery pipeline. As Vertex increases its capabilities in manufacturing, marketing and sales, collaborative agreements will still 
remain an important part of the Company's business strategy, allowing the Company to select from its broad pipeline those products 
best suited to commercialization by the Company, while retaining a substantial interest in the commercial success of partnered 
projects. In its collaborative agreements, Vertex seeks to participate, through manufacturing, co-promotion and marketing rights, in 
generating significant downstream revenue for each of its products. 

PRODUCT DEVELOPMENT AND RESEARCH PROGRAMS 

The following are the Company's most advanced research and development programs. 

CLINICAL DEVELOPMENT PROGRAMS 

AGENERASE-TM- 

OVERVIEW 

Agenerase-TM- (Glaxo Wellcome's brand name for the compound amprenavir) is the Company's most advanced product. Agenerase, a 
second generation HIV protease inhibitor, is an orally deliverable drug for the treatment of HIV infection and AIDS. It was developed 
by Vertex in collaboration with Glaxo Wellcome plc. and Kissei Pharmaceutical Co., Ltd. Glaxo Wellcome has filed a New Drug 
Application for Agenerase with the U.S. Food and Drug Administration in the United States and has made equivalent filings in Europe, 
Canada and other countries. The U.S. FDA has designated Agenerase as a fast-track product, and FDA review is expected to be 

   2002.  EDGAR Online, Inc.

completed by mid-April 1999. Upon approval by regulatory authorities, Glaxo Wellcome will market Agenerase in the United States 
and other countries, with co-promotion assistance by the Company. Kissei is the Company's partner for the development and 
commercialization of amprenavir in the Far East. 

World sales of antiviral drugs for the treatment of AIDS and HIV infection were an 

BACKGROUND 

estimated $4 billion in 1998. Nevertheless, there remains a significant need for new therapeutic options for the management of HIV 
infection. In the United States and elsewhere, the majority of HIV-infected patients are undiagnosed or untreated with any antiviral 
drug. The antiviral drugs currently on the market have significant limitations, creating a significant market opportunity for Agenerase. 
Suboptimal treatment strategies and poor adherence to complex drug regimens result in the development of drug-resistant virus and 
need for subsequent changes in treatment regimens for many patients. Switching antiviral medications is therefore done on a routine 
basis, also resulting in the need for new agents. 

Page 4 

HIV protease is a key enzyme involved in the viral replication of HIV. Agenerase is an HIV protease inhibitor designed by Vertex to 
effectively block the replication of HIV and to possess key competitive characteristics. Four other companies are marketing protease 
inhibitors approved by the FDA. However, clinician and patient acceptance of these products may be limited by complex dosing 
regimens, which can result in poor patient compliance, and by dose-limiting side effects. 

The Company believes that Agenerase compares favorably with the protease inhibitors currently on the market in terms of potency, 
tolerability, dosing regimen and resistance profile. Agenerase is taken twice daily, without restrictions regarding dosing with or 
without food or water. In addition, clinical studies have shown that Agenerase penetrates the tissues of the central nervous system, 
which may be important in preventing the development of resistance. Agenerase has a unique IN VITRO resistance profile, and 
preliminary clinical data have shown that patients previously treated with Agenerase can be successfully treated with a subsequent 
protease inhibitor. To date, HIV has been shown to develop resistance to antiviral drugs, including currently marketed HIV protease 
inhibitors. Preliminary data also suggest that Agenerase is less associated with blood lipid abnormalities than other HIV protease 
inhibitors. However, there can be no assurance that disease resistance or other factors will not limit the efficacy of Agenerase. 

In addition to protease inhibitors, there are two other classes of antiviral drugs currently approved for the treatment of HIV/AIDS. 
Nucleoside reverse transcriptase inhibitors, or NRTIs, include AZT, d4T, ddI, ddC, 3TC and abacavir. Non-nucleoside reverse 
transcriptase inhibitors, or NNRTIs, include efavirenz, nevirapine and delavirdine. Both classes of drugs act by inhibiting reverse 
transcriptase, a viral enzyme required for replication. The clinical utility of each of these drugs is limited by significant side effects and 
by the development of viral resistance. Clinical studies have demonstrated that therapies for HIV infection which comprise a 
combination of three or more drugs including at least two drug classes ("drug cocktails") are superior in potency and durability of 
response to those which do not. Such combinations are currently accepted as the standard of care for HIV infection. 

PROGRAM STATUS 

Glaxo Wellcome, the Company's HIV research and development partner, has filed for U.S. regulatory approval for marketing 
Agenerase and has made equivalent regulatory filings in Europe, Canada and other countries. Glaxo Wellcome is the global leader in 
sales of HIV therapeutics. To support Agenerase in the marketplace, Vertex has established a small clinical liaison force to build 
relationships with physicians and patient treatment advocates. The Company will receive a royalty based on Glaxo Wellcome's sales of 
Agenerase. Agenerase has already been made available to more than 2,000 patients through an early access program. 

Glaxo Wellcome filed the New Drug Application for Agenerase on October 15, 1998, and the FDA has designated Agenerase for 
review under the its guidelines for accelerated approval. Vertex and Glaxo Wellcome are continuing development activities with 
respect to Agenerase, including on-going Phase III studies to support the full approval of the drug, and on-going and planned Phase IV 
studies designed to further characterize and expand the utilization of the product. 

Page 5 
There can be no assurance, however, that the New Drug Application will be approved within the expected time-frame or at all, that full 
approval will be granted on the basis of ongoing Phase III studies, or that the Phase IV studies will commence as planned or will be 
successful. 

In 1995, Kissei completed single dose and multi-dose, placebo-controlled, Phase I clinical trials. Vertex expects that in 1999 Kissei 
will initiate a Phase II/III efficacy trial in HIV-positive patients in Japan. The results of such trials, together with clinical data from the 
Glaxo Wellcome trials, could form the basis for a filing for marketing approval of amprenavir in Japan. There can be no assurance, 

   2002.  EDGAR Online, Inc.

however, that these clinical trials will commence or proceed as currently anticipated. 

In collaboration with Glaxo Wellcome, Vertex is also engaged in research to develop new formulations of amprenavir. In addition, 
Vertex and Glaxo Wellcome are continuing to evaluate new lead classes of third generation HIV protease inhibitors discovered under 
their HIV research collaboration. 

PATENTS 

The Company has patents and pending patent applications in the United States and in certain foreign countries covering intellectual 
property developed as part of the Company's HIV research and development program. These include issued United States patents that 
cover classes of chemical compounds, pharmaceutical formulations and/or uses of the same for treating HIV infection and AIDS. The 
patents include specific coverage for amprenavir, the Company's lead drug candidate for treating HIV infection and AIDS, 
pharmaceutical formulations containing amprenavir and methods of using of amprenavir to treat HIV infection or AIDS-related central 
nervous system disorders. Another issued United States patent covers processes for preparing synthetic intermediates useful in the 
synthesis of a class of compounds that includes amprenavir. The Company also has a non-exclusive, worldwide license under certain 
G.D. Searle & Company patent applications claiming HIV protease inhibitors. 

CANCER MULTIDRUG RESISTANCE (MDR) PROGRAM 

OVERVIEW 

Vertex is developing novel compounds to treat and prevent the occurrence of drug resistance associated with the failure of cancer 
chemotherapy. Vertex is developing Incel-TM- (also referred to as biricodar dicitrate or VX-710), a compound that blocks major 
multidrug resistance mechanisms, including P-glycoprotein, or P-gp, and multidrug resistance associated protein, or MRP. Incel, an 
intravenous compound, is intended to be administered in combination with cancer chemotherapy agents, such as doxorubicin, 
paclitaxel, vincristine, etoposide and mitoxantrone. Vertex is conducting Phase II clinical trials of Incel in five different types of 
cancer. In addition, Vertex is conducting a Phase I/II clinical trial of the compound VX-853, an oral MDR inhibitor, in patients with 
solid tumors. The Company retains all commercial rights to Incel worldwide, except for Canada, where BioChem Pharma Inc. has 
rights under a collaboration agreement with Vertex. 

BACKGROUND 

The American Cancer Society estimates that during 1998 more than 1.2 million people in the United States were diagnosed with 
invasive cancer and more than 560,000 people in the U.S. died from such cancers. The Company believes that a significant number of 
these patients fail to respond or relapse following chemotherapy because of multidrug resistance, or MDR. 

Multidrug resistance is frequently associated with the failure of chemotherapy. A major contributing factor to MDR is the presence of 
molecular pumps, including P-gP and MRP, that function to expel chemotherapeutic agents from cancer cells, preventing the sustained 
delivery of 

potent levels of the chemotherapeutic agents required for therapeutic benefit. As a consequence, such resistant tumor cells cannot be 
killed efficiently by anticancer drugs such as doxorubicin, vincristine, etoposide and paclitaxel. P-gp has been associated with MDR in 
a variety of cancers including liver cancer, breast cancer, soft tissue sarcoma, prostate cancer, colon cancer, pancreatic cancer, acute 
myelogenous leukemia, multiple myeloma and certain lung cancers. MRP was recently identified as another drug efflux pump and is 
also associated with resistance observed. 

Page 6 

No drug has been approved by the FDA specifically for the treatment of MDR, but several compounds are in advanced clinical studies. 
Certain agents, such as dex-verapamil and cyclosporin A, have been shown in preliminary human studies to have some promise for 
overcoming clinical resistance to certain commonly used chemotherapeutic agents. The Company believes these drugs affect only a 
subset of the MDR pumps and may have side effects that could limit broad use. Second generation multidrug reversing agents, such as 
valspodar, a cyclosporin analog, are also currently being evaluated by other companies. 

PROGRAM STATUS 

Vertex's lead compound, Incel, has displayed potent activity IN VITRO as an inhibitor of MDR for a number of chemotherapeutic 
agents in a variety of tumor types. Vertex has completed two Phase I/II studies with Incel in combination with doxorubicin and with 
paclitaxel. Vertex also completed a Phase II study of Incel in combination with doxorubicin in patients with liver cancer. Vertex does 
not intend to pursue this indication further at the present time. The Company is currently conducting five Phase II clinical studies of 

   2002.  EDGAR Online, Inc.

Incel. Preliminary results from the Phase II studies indicate that sustained blood levels of Incel in excess of those necessary to reverse 
MDR IN VITRO can be achieved. Pharmacokinetic data of Incel in combination with paclitaxel indicated that the compound has a 
dose sparing effect, suggesting that approximately one-half the dose of paclitaxel can be used when that drug is administered with 
Incel. 

Phase II clinical trials of Incel are currently being conducted in the following indications: 

- BREAST CANCER. In 1997, the Company initiated a Phase II multi-center trial to assess the safety and efficacy of the 
co-administration of Incel and paclitaxel in patients with metastatic breast cancer. Interim data reported at the 21st Annual Breast 
Cancer Symposium in 1998 suggest that Incel may play a role in restoring the activity of paclitaxel in some patients with advanced 
breast cancer whose tumors have previously been resistant to paclitaxel therapy. 

- SOFT TISSUE SARCOMA. The Company began a Phase II trial in 1997 to study Incel in combination with doxorubicin in patients 
with soft tissue sarcoma. Preliminary results from 11 patients, announced at the 4th Connective Tissue Oncology Society Meeting in 
1998 indicated that treatment with Incel and doxorubicin was well-tolerated, showed no marked drug interactions, and indicated that 
Incel could also play a role in restoring the activity of doxorubicin in this patient population. 

- OVARIAN CANCER. A study of Incel in combination with paclitaxel in patients with ovarian cancer began in 1997. This open-label 
Phase II clinical trial will evaluate the tolerability, safety, pharmacokinetics and efficacy of the compound with paclitaxel. 

- PROSTATE CANCER. In 1998, Vertex began a Phase II clinical trial evaluating the pharmacokinetics and efficacy of Incel in 
combination with mitoxantrone and prednisone in patients with advanced hormone-refractory prostate cancer. This study is the first to 
examine Incel's activity in an exclusively chemotherapy-naive patient population. 

- SMALL CELL LUNG CANCER. Also begun in 1998, this is an open-label, multi-center trial to evaluate the tolerability, 
pharmacokinetics and anti-tumor activity of Incel in combination with doxorubicin and vincristine in patients with progressive disease, 
who responded to initial 

Page 7 
therapy and subsequently relapsed. This study will try to correlate the multidrug resistance profile of each patient with any therapeutic 
response to Incel. 

Preliminary results from some of these studies are expected in 1999. The results will help to determine the most appropriate regimens 
and indications for Phase III clinical development of Incel. However, there can be no assurance that additional clinical trials will 
commence or trials currently under way will proceed as currently anticipated. The clinical efficacy of the suppression of mechanisms 
of action of MDR in chemotherapy in the treatment of cancer is unproven, and, therefore, there can be no assurance that the 
Company's MDR compounds in development will improve the efficacy of chemotherapy. 

PATENTS 

The Company has patents and pending patent applications in the United States and in certain foreign countries covering intellectual 
property developed as part of the Company's MDR research and development program. These include issued United States patents 
claiming Incel and structurally related compounds, VX-853 and structurally related compounds, and other compounds for treating 
multidrug resistance. 

IMPDH PROGRAM 

OVERVIEW 

IMPDH is an enzyme that controls the synthesis of certain nucleotides which are required for RNA and DNA synthesis. Most cell 
types can use an alternative pathway if IMPDH is inhibited, but a few cell types, such as lymphocytes and virus-infected cells, are 
completely dependent on this enzyme. IMPDH inhibitors thus selectively block the proliferation of lymphocytes and the replication of 
certain viruses, and Vertex believes that IMPDH inhibitors may be useful both in immunosuppression and as antiviral agents. VX-497 
is a novel, orally administered IMPDH inhibitor designed by Vertex. Vertex is conducting Phase II clinical trials of VX-497 for the 
treatment of severe chronic plaque-type psoriasis and for the treatment of hepatitis C virus ("HCV") infection. The Company retains 
all commercial rights to compounds resulting from this program. 

BACKGROUND 

   2002.  EDGAR Online, Inc.

IMPDH catalyzes a key step in nucleotide biosynthesis. IMPDH inhibition appears to selectively suppress immune system cells while 
leaving other cells unaffected and may play an important role in down regulating inappropriate immune responses common to a range 
of human diseases, including multiple sclerosis, inflammatory bowel disease, psoriasis, rheumatoid arthritis and systemic lupus 
erythematosus. IMPDH inhibitors can be used to prevent the rejection of transplanted organs and may also have anti-viral effects. 

The Company is aware of only two IMPDH inhibitors currently on the market in the United States. Hoffmann-La Roche's 
mycophenolate mofetil is approved for use in combination with cyclosporine to prevent acute rejection in kidney and heart 
transplantation. Schering-Plough's ribavirin was approved in 1998 for treatment, in combination with alpha interferon, of Hepatitis C 
infection. The Company believes that compound-specific side effects of mycophenolate mofetil and ribavirin may limit their use for 
chronic autoimmune disorders. 

Psoriasis was selected as the first chronic autoimmune indication for VX-497 development. There is a sigificant medical need for new 
therapies for moderate to severe psoriasis patients. A chemically unrelated IMPDH inhibitor, mycophenolic acid, was investigated in 
psoriasis in the 1970's. Despite clear-cut efficacy, its development was terminated due to toxicity and tolerability 

Page 8 
problems. It did however, establish proof of the principle of IMPDH inhibition as a therapeutic approach for psoriasis. In addition to 
topical and intralesional medications, moderate to severely afflicted patients are treated with phototherapy (UVB and PUVA), and 
systemic drugs such as methotrexate, retinoids, and cyclosporine. However, these treatments require extensive medical supervision, 
and/or have serious toxic side effects. 

As an immunosuppressive, VX-497 may block the growth of certain lymphocyte populations that contribute to the inflammation of the 
liver in HCV patients. VX-497 may also have a direct antiviral effect on HCV and other viruses. Although it has not been possible to 
test potential drugs against hepatitis C IN VITRO because an HCV replication model has not been available, studies of VX-497 
against related viruses have demonstrated that VX-497 may be a powerful inhibitor of viral replication. 

According to the U.S. Center for Disease Control (CDC) estimates, approximately 4 million people in the United States are infected 
with HCV, and there are estimated to be approximately 170 million chronic carriers of the virus worldwide. Current treatment options 
are limited. Various forms of interferon alpha are the most common treatment used, but provide lasting benefit in less than 20% of 
patients. Recent research results indicate that combination therapy of interferon plus ribavirin may increase the long-term rate of 
sustained response to treatment. Still, more than 50% of patients fail combination ribavirin-interferon therapy, and additional safe and 
effective treatments for HCV infection are needed. 

PROGRAM STATUS 

A Phase I clinical trial investigating the pharmacokinetics and tolerability of VX-497 in escalating single doses in healthy subjects was 
completed in the United Kingdom in early 1998. Data from that study show that VX-497 is well tolerated and achieves blood levels 
well above the threshhold necessary to inhibit IMPDH IN VITRO. 

Vertex is now conducting a Phase II clinical trial of VX-497 to determine the tolerability and pharmacokinetic profile of VX-497 in 
psoriasis patients. This is a randomized, blinded dose range-finding study. Preliminary safety and efficacy of VX-497 are being 
assessed in the 12-week trial. Vertex is also conducting a Phase II study of VX-497 for the treatment of HCV infection. Preliminary 
safety and efficacy are being assessed in this four-week dose range-finding monotherapy trial. 

Future clinical development of VX-497 in HCV may involve assessment of the compound in combination with other agents such as 
interferon alpha. The Company may also expand clinical development of VX-497 into additional autoimmune, transplant and antiviral 
indications in the future. There can be no assurance, however, that additional clinical trials will commence or that studies currently 
under way will proceed as anticipated. 

PATENTS 

The Company has patents and pending patent applications in the United States and in certain foreign countries covering intellectual 
property developed as part of the Company's IMPDH research and development program. These include an issued United States patent 
which covers a class of chemical compounds, pharmaceutical compositions containing such compounds, and methods of using those 
compounds to treat or prevent IMPDH-mediated diseases. The class of compounds covered by this patent includes VX-497. 

ICE PROGRAM 

Page 9 

   2002.  EDGAR Online, Inc.

OVERVIEW 

Vertex is conducting research and development on inhibitors of interleukin-1 beta converting enzyme (ICE) for the treatment of acute 
and chronic inflammatory conditions, including rheumatoid arthritis (RA). The Company is collaborating with Hoechst Marion 
Roussel (HMR) in the development of the ICE inhibitor compound VX-740. A Phase I clinical trial of VX-740 in healthy volunteers 
was recently completed. Inhibitors of ICE may have application to a wide range of chronic and acute inflammatory diseases, such as 
rheumatoid arthritis, osteoarthritis, inflammatory bowel disease, sepsis, and pancreatitis. 

BACKGROUND 

Elevation of interleukin-1 beta (IL-1 beta) levels has been correlated to a number of acute and chronic inflammatory diseases. There 
are approximately 2.1 million patients with rheumatoid arthritis in the United States alone. Numerous companies are seeking to 
develop drugs to treat these conditions through various mechanisms. However, although several companies are pursuing ICE as a drug 
target, Vertex is not aware of any company with an ICE-inhibiting compound in clinical development, and there currently are no IL-1 
beta inhibitors approved for marketing. 

Inside specialized immune system cells, ICE activates the inflammatory cytokine protein IL-1 beta and the protein gamma interferon, a 
key immunoregulator that modulates antigen presentation, T-cell activation, and cell adhesion. This triggers a cascade of events that 
produces inflammation. Vertex and HMR scientists have designed several classes of small molecule ICE inhibitors, including VX-740, 
the development candidate in the collaboration. 

Currently, non-steroidal anti-inflammatory drugs and other anti-inflammatory approaches which provide some symptomatic relief 
without altering disease progression, are used extensively in the treatment of RA. A few disease-modifying anti-rheumatic drugs such 
as methotrexate have been available or have been investigated for a number of years, but have toxicities that limit their long-term use. 
New biologics such as etanercept (Enbrel) and infliximab (Remicade) seek to attenuate the anti-inflammatory process by targeting 
TNF-alpha. In addition, studies with soluble IL-1 receptor and IL-1 receptor antagonist have shown reduced joint destruction in RA 
patients. However, current anticytokine therapies for RA and inflammatory bowel disease are protein-based and must be injected. The 
Company believes that an oral therapy which can alter the course of disease with few side effects would be a major addition to the RA 
therapeutic arsenal. 

PROGRAM STATUS 

The first clinical trial of VX-740 was a study involving 18 healthy volunteers begun in 1998. This study was designed to test the 
pharmacokinetics and tolerability of the compound in a range of single doses. Preliminary results of this study indicate that the drug 
was well tolerated. VX-740 has been shown to be orally active in several animal models of human inflammatory disease, including 
models for acute and chronic arthritis. Vertex expects that a Phase II study of VX-740 for the treatment of rheumatoid arthritis will be 
the next step in the development program. However, there can be no assurance that clinical trials will commence or proceed as 
currently anticipated. 

PATENTS 

The Company has patents and pending patent applications in the United States and in certain foreign countries covering intellectual 
property developed as part of the Company's ICE research and development program. These include issued United States patents 
covering several

different classes of compounds useful as inhibitors of ICE, pharmaceutical compositions containing those compounds and methods of 
using those compounds to treat ICE-related diseases. These patents and applications include a series of patents and applications 
purchased from Sanofi S.A., in July 1997. The Company also has a United States patent obtained from Sanofi S.A. that covers DNA 
sequences encoding ICE. 

NEUROPHILIN LIGAND PROGRAM 

OVERVIEW 

The goal of the Neurophilin Ligand Program is to discover and develop drugs useful in the treatment of neurological disorders such as 
peripheral neuropathies, including diabetic neuropathy, Parkinson's disease, trauma, and amyotrophic lateral sclerosis, or ALS. Vertex 
has used information-driven drug design to synthesize a library of orally available small molecule compounds that have the potential to 
promote recovery of nerve function and nerve growth. Vertex is engaged in worldwide strategic partnership with Schering AG, 

   2002.  EDGAR Online, Inc.

Germany for research, development and commercialization of neurophilin ligands for the treatment of a variety of neurological 
disorders. In November 1998, Vertex started a Phase II clinical trial of timcodar dimesylate (also referred to as VX-853) in diabetic 
neuropathy patients. Schering AG has an option to co-develop timcodar dimesylate with Vertex under the collaboration agreement. 

BACKGROUND 

Neurodegenerative disorders are among the diseases with the fewest available effective treatments. Central nervous system disorders 
such as Alzheimer's disease, Parkinson's disease and multiple sclerosis affect millions of patients worldwide, and for some of these 
there are no approved therapies that alter the course of disease progression. Peripheral neuropathies encompass a wide spectrum of 
clinical syndromes for which treatments of only limited efficacy are available. Diabetic neuropathy, the indication for Vertex's ongoing 
Phase II study of timcodar dimesylate, is the most common identifiable cause of neuropathy. There are approximately 1.3 million 
patients with moderate to severe diabetic neuropathy in the United States. 

Effective treatment of both central and peripheral neurological disorders has long been hampered by the inability to slow, arrest, or 
reverse nerve damage or progression. Other companies are developing various neurotrophic factors (proteins) for these indications, but 
the Company believes their clinical utility is likely to be limited. Based on Vertex's extensive research in the field of 
immunosuppressive drugs, the Company has been able to generate a large number of compounds, known as neurophilin ligands, that 
trigger nerve growth activity. Extensive IN VITRO and IN VIVO studies conducted with a reference compound designed by Vertex 
support the broad potential of Vertex's neurophilin ligands in the treatment of degenerative central nervous system and peripheral 
nervous system diseases. Vertex's clinical neurophilin ligand candidate, timcodar, has demonstrated potent activity in promoting 
neurite outgrowth and functional recovery of nerves in preclinical studies. Vertex researchers are still seeking to determine the 
mechanism of action of neurophilin ligands. 

PROGRAM STATUS 

In October 1998, Vertex started a Phase II clinical trial with timcodar dimesylate. Approximately 70 patients will be enrolled in the 
trial, which is expected to be conducted at eight centers in the United States. This is a double-blind, placebo controlled trial. Primary 
objectives will be to evaluate the safety and tolerability of six different dose regimens of timcodar administered orally over a 28-day 
period. Nerve function will also be monitored. A single-dose Phase I study of four different doses of timcodar in healthy volunteers 
was completed in 1998, providing support for Phase II clinical development in the indication of diabetic neuropathy. IN 

VITRO results have shown timcodar's ability to promote neurite outgrowth, and IN VIVO results have shown that timcodar can 
prevent neural dysfunction in a model of diabetic polyneuropathy.

PATENTS 

The Company has patents and pending patent applications in the United States and in certain foreign countries covering intellectual 
property developed as part of the Company's Neurophilin research and development program. These include issued United States 
patents covering the use of various classes of chemical compounds to treat a wide variety of neurological disorders. One of these 
patents specifically covers the use of timcodar to treat neurological disorders. 

P38 MAP KINASE PROGRAM 

OVERVIEW 

Vertex is collaborating with Kissei on the design, development and commercialization of inhibitors of p38 MAP kinase. The p38 MAP 
kinase is a human enzyme involved with the onset and progression of inflammation and programmed cell death. The objective of 
Vertex's research collaboration with Kissei is to identify and extensively evaluate compounds that target p38 MAP kinase to develop 
novel, orally active drugs for the treatment of inflammatory diseases, such as rheumatoid arthritis, asthma, and Crohn's disease, and 
neurological diseases such as stroke. In March 1999, the Company initiated a Phase I clinical trial with VX-745, a novel orally 
administered investigational drug targeting p38 MAP kinase. 

BACKGROUND 

The mitogen-activated protein (MAP) kinases are a family of structurally-related human enzymes involved in intracellular signaling 
pathways that enable cells to respond to their environment. When activated, the p38 MAP kinase triggers production of the cytokines 
interleukin-1 (IL-1), interleukin-6 
(IL-6) and tumor necrosis factor TNF-alpha. Excess levels of IL-1 and TNF-alpha are associated with a broad range of acute and 

   2002.  EDGAR Online, Inc.

chronic inflammatory diseases. They also play an important role in programmed cell death associated with ischemia and stroke, and in 
neurodegenerative diseases such as Alzheimer's and Parkinson's disease. Vertex is aware of several other companies that are 
developing p38 MAP kinase inhibitors. 

PROGRAM STATUS 

During 1998, Vertex and Kissei selected VX-745 as a lead drug development candidate targeting p38 MAP kinase. The Company 
began a Phase I clinical trial of the compound in healthy volunteers in early 1999. The study, which is being conducted in Europe, will 
assess the compound's safety and help to determine the dose range for subsequent studies. The Phase I randomized, blinded clinical 
trial is designed to test the pharmacokinetics and tolerability of VX-745 in escalating single doses in healthy volunteers. The trial will 
assess the ability of different doses of VX-745 to inhibit experimentally induced TNF-alpha production using specific biochemical 
assays. Following completion of the study, Vertex may conduct additional single or multidose trials of VX-745. VX-745 has been 
shown to slow disease progression in animal models of immune-mediated arthritis. However, there can be no assurance that clinical 
trials will commence or proceed as currently anticipated. 

PATENTS 

Page 12 

The Company has pending patent applications in the United States and in certain foreign countries covering intellectual property 
developed as part of the Company's p38 MAP Kinase research and development program. Certain of the applications cover a class of 
chemical compounds that includes VX-745, as well as VX-745 specifically, compositions comprising those compounds and the use of 
those compounds to treat p38-related disorder. 

RESEARCH PROGRAMS 

HEPATITIS C VIRUS PROGRAMS 

The Company is conducting two discovery research programs to develop compounds to treat hepatitis C. Identified in 1989, the 
hepatitis C virus (HCV) causes chronic inflammation in the liver. In a majority of patients, HCV establishes a chronic infection that 
can persist for decades and eventually lead to cirrhosis, liver failure and liver cancer. HCV infection represents a significant medical 
problem worldwide for which there is inadequate or no therapy for a majority of patients. Sources at the CDC have estimated that 
approximately 4 million Americans, or more than 1% of the population, may be infected with HCV, and there are estimated to be more 
than 100 million chronic carriers of the virus worldwide. Currently, there is no vaccine available to prevent hepatitis C infection. The 
only drugs approved for the treatment of hepatitis C are interferon alpha and ribavarin. Combination therapy with interferon alpha and 
ribavarin is the most successful treatment currently available, but over 50% of patients still failed to show long-term sustained 
response to that combination, and safe and effective treatments for HCV infection are needed. 

HEPATITIS C PROTEASE 

The hepatitis C NS3-4A serine protease is a virally encoded enzyme generally believed to be essential for replication of HCV. Under 
an agreement signed during 1997, Vertex and Eli Lilly and Company are collaborating on the research, development and 
commercialization of novel, orally active HCV protease inhibitors for the treatment of hepatitis C infection. This research derives 
heavily from detailed structural information about the protease, discovered and developed by Vertex researchers. 

The Company has pending patent applications in the United States and in certain foreign countries covering intellectual property 
developed as part of the Company's Hepatitis C Protease research and development program. Vertex has an issued United States patent 
covering an assay useful to evaluate potential inhibitors of Hepatitis C protease. 

HEPATITIS C HELICASE 

Vertex is also conducting discovery research to design orally deliverable drugs to inhibit the hepatitis C virus helicase. The NS3 
helicase enzyme is believed to play an essential role in the infectious cycle of the hepatitis C virus by aligning viral DNA in its proper 
configuration for replication. Therefore, the HCV helicase represents an attractive target for drug discovery. 

Researchers from Vertex solved the three-dimensional atomic structure of the hepatitis C virus NS3 helicase. Vertex is using the 
structural information to identify and optimize inhibitors of the enzyme, employing structure-based techniques, including cluster-based 
screening, and 

Page 13 

   2002.  EDGAR Online, Inc.

computational, combinatorial, and medicinal chemistry, to design novel small molecule inhibitors of the HCV helicase for clinical 
development as new antiviral drugs to treat HCV infection. 

The Company has pending patent applications in the United States covering intellectual property developed as part of the Company's 
Hepatitis C Helicase research and development program. These applications cover Hepatitis C helicase inhibitors and the X-ray crystal 
structure of Hepatitis C helicase. 

CASPASE INHIBITORS PROGRAM 

Vertex is conducting a major multidisciplinary research effort to design of novel, small molecule inhibitors of apoptosis (programmed 
cell death) for the treatment of a variety of pathological conditions including major neurodegenerative and cardiovascular diseases. In 
this separate caspase inhibitor program, Vertex scientists are capitalizing on expertise gained through the Company's successful design 
and optimization of inhibitors of ICE (Caspase-1). Recent highlights include the solution of the caspase-3 structure by X-ray 
crystallography and the first description of the caspase-9 gene knockout mouse, establishing that this enzyme is of particular 
importance in neurobiology. With respect to drug discovery, Vertex's caspase research has resulted in the identification of novel 
compounds with activity in enzyme assays, cellular assays, and animal models. The goal of Vertex's caspase inhibitors program is to 
discover and develop novel drugs useful for treating neurodegenerative disorders such as Alzheimer's and Parkinson's disease and for 
decreasing the tissue damage in myocardial infarction and stroke. 

JNK3 MAP KINASE INHIBITORS PROGRAM 

Vertex is currently engaged in a research effort to identify JNK3 MAP kinase inhibitors. Vertex's studies have been accelerated by the 
experience gained in Vertex's p38 MAP kinase program with Kissei. Jun N-terminal kinase (JNK) is a member of the same group of 
structurally-related enzymes as p38 MAP kinase. Recent findings suggest that JNK3 plays an important role in central nervous system 
disorders such as epilepsy, stroke and Alzheimer's Disease. JNK3 also has been implicated in Parkinson's disease. Vertex has solved 
and in 1998 reported in the journal STRUCTURE the X-ray crystal structure of JNK3 complexed to an analog of the co-factor 
molecule ATP. Using proprietary structural information of the JNK3 and other MAP kinase enzymes, Vertex scientists selected initial 
compounds for investigation as potential inhibitors. Vertex has identified several novel classes of JNK3 MAP kinase inhibitors and is 
currently using advanced drug discovery technology to move lead compounds toward clinical candidate status. 

CORPORATE COLLABORATIONS 

Vertex has entered into corporate collaborations with pharmaceutical companies that provide financial and other resources, including 
capabilities in research, development, manufacturing, and sales and marketing, to support the Company's research and development 
programs. At present, the Company has the following major corporate collaborations. 

GLAXO WELLCOME PLC.

ALTUS BIOLOGICS INC. 

Altus Biologics Inc. develops, manufactures and markets products based on a novel and proprietary technology for stabilizing 
proteins. At December 31, 1998, Vertex owned approximately 70% of the capital stock of Altus. In February 1999, Vertex 
restructured its investment in Altus. As part of the transaction, Vertex provided Altus $3 million of cash and surrendered its shares of 
Altus preferred stock in exchange for two new classes of preferred stock and warrants. The new preferred stock provides Vertex with a 
minority ownership position in Altus, and the warrants, which become exercisable upon certain events, will provide Vertex with 
significant additional ownership potential. As a result of the transaction, Altus now operates independently from Vertex. In addition, 
Vertex has retained a non-exclusive royalty-free right to use Altus' technology for discovering, developing and manufacturing small 
molecule drugs. 

PATENTS AND PROPRIETARY INFORMATION 

The Company has rights in certain patents and pending patent applications that relate to compounds it is developing and methods of 
using such compounds, as discussed above. In addition, the Company actively seeks, when appropriate, protection for its products and 
proprietary information by means of United States and foreign patents, trademarks and contractual arrangements. Vertex has pending 
applications in the United States, and foreign counterpart applications in countries it deems appropriate, for all of its most advanced 
research and development programs. In addition, the Company relies upon trade secrets and contractual arrangements to protect 
certain of its proprietary information and products. 

There can be no assurance that any patents will issue from any of the Company's patent applications or, even if patents issue or have 
issued, that the claims thereof will provide the Company with any significant protection against competitive products or otherwise be 
valuable commercially. Legal standards relating to the validity of patents and the proper scope of their claims in the biopharmaceutical 
field are still evolving, and there is no consistent policy regarding the breadth of claims allowed in biopharmaceutical patents. No 
assurance can be given as to the Company's ability to avoid infringing, and thus having to negotiate a license under, any patents issued 
to others, or that a license to such patents would be available on commercially acceptable terms, if at all. See Item 3, "Legal 
Proceedings." 

Further, there can be no assurance that any patents issued to or licensed by the Company will not be infringed by the products of 
others, which may require the Company to engage in patent infringement litigation. In addition to being a party to patent infringement 

Page 17 

   2002.  EDGAR Online, Inc.

litigation, the Company could be required to participate in interference proceedings declared by the United States Patent and 
Trademark Office. Defense or prosecution of patent infringement litigation, as well as participation in interference proceedings, can be 
expensive and time consuming, even in those instances in which the outcome is favorable to the Company. If the outcome of any such 
litigation or proceeding were adverse, the Company could be subject to significant liabilities to third parties, could be required to 
obtain licenses from third parties or could be required to cease sales of the affected products, any of which could have a material 
adverse effect on the Company. 

Much of the Company's technology and many of its processes are dependent upon the knowledge, experience and skills of key 
scientific and technical personnel. To protect its rights to its proprietary know-how and technology, the Company requires all 
employees, consultants, advisors and collaborators to enter into confidentiality agreements that prohibit the disclosure of confidential 
information to anyone outside the Company. These agreements require disclosure and assignment to the Company of ideas, 
developments, discoveries and inventions made by employees, consultants, advisors and collaborators. However, there can be no 
assurance that these agreements will effectively prevent disclosure of the Company's confidential information or will provide 
meaningful protection for the Company's confidential information if there is unauthorized use or disclosure. 

MANUFACTURING 

The Company relies on third party manufacturers and collaborative partners to produce its compounds for preclinical and clinical 
purposes and may do so for commercial production of any compounds that are approved for marketing. Commercial manufacturing of 
Agenerase will be done, at least initially, by Glaxo Wellcome. Vertex retains the option to manufacture a portion of Glaxo Wellcome's 
requirements for bulk drug substance. If Vertex were to exercise that option, it would rely upon one or more contract manufacturers to 
manufacture the Agenerase bulk drug substance on its behalf. 

The Company has established a quality assurance program, including a set of standard operating procedures, intended to ensure that 
third party manufacturers under contract produce the Company's compounds in accordance with the FDA's current Good 
Manufacturing Practices, or cGMP, and other applicable regulations. 

The Company believes that all of its existing compounds can be produced using established manufacturing methods, primarily through 
standard techniques of pharmaceutical synthesis. The Company believes that it will be able to continue to negotiate third party 
manufacturing arrangements on commercially reasonable terms and that it will not be necessary for it to develop internal 
manufacturing capability in order to successfully commercialize its products. The Company's objective is to maintain flexibility in 
deciding whether to develop internal manufacturing capabilities for certain of its potential products. However, in the event that the 
Company is unable to obtain contract manufacturing, or obtain such manufacturing on commercially reasonable terms, it may not be 
able to commercialize its products as planned. The Company has limited experience in manufacturing pharmaceutical or other 
products or in conducting manufacturing testing programs required to obtain FDA and other regulatory approvals, and there can be no 
assurance that the Company will further develop such capabilities successfully. 

Since most of the Company's potential products are at an early stage of development, the Company will need to improve or modify its 
existing manufacturing processes and capabilities to produce commercial quantities of any drug product economically. The Company 
cannot quantify the time or expense that may ultimately be required to improve or modify its existing process technologies, but 

it is possible that such time or expense could be substantial. 

Page 18 

The production of Vertex's compounds is based in part on technology that the Company believes to be proprietary. Vertex may license 
this technology to contract manufacturers to enable them to manufacture compounds for the Company. In addition, a contract 
manufacturer may develop process technology related to the manufacture of Vertex's compounds that the manufacturer owns either 
independently or jointly with the Company. This would increase the Company's reliance on such manufacturer or require the Company 
to obtain a license from such manufacturer in order to have its products manufactured. 

Some of the Company's current corporate partners have certain manufacturing rights with respect to the Company's products under 
development, and there can be no assurance that such corporate partners' rights will not impede the Company's ability to conduct the 
development programs and commercialize any resulting products in accordance with the schedules and in the manner currently 
contemplated by the Company. 

COMPETITION 

The Company is engaged in pharmaceutical fields characterized by extensive research efforts, rapid technological progress and intense 
competition. There are many public and private companies, including pharmaceutical companies, chemical companies and 

   2002.  EDGAR Online, Inc.

biotechnology companies, engaged in developing products for the same human therapeutic applications as those targeted by Vertex. In 
order for the Company to compete successfully, it must demonstrate improved safety, efficacy, ease of manufacturing and market 
acceptance of its products over those of its competitors who have received regulatory approval and are currently marketing their drugs. 
In the field of HIV protease inhibition, Merck & Co., Inc., Abbott Laboratories, Inc., Hoffmann-La Roche, and Agouron 
Pharmaceuticals, Inc. have HIV protease inhibitor drugs that are already on the market. Many of the Company's competitors have 
substantially greater financial, technical and human resources than those of the Company and more experience in the development of 
new drugs. See "Risk Factors--Vertex Faces Substantial Competition." 

GOVERNMENT REGULATION 

The Company's development, manufacture and potential sale of therapeutics are subject to extensive regulation by United States and 
foreign governmental authorities. In particular, pharmaceutical products are subject to rigorous preclinical and clinical testing and to 
other approval requirements by the FDA in the United States under the Food, Drug and Cosmetic Act and by comparable agencies in 
most foreign countries. 

As an initial step in the FDA regulatory approval process, preclinical studies are typically conducted in animals to identify potential 
safety problems. For certain diseases, animal models exist that are believed to be predictive of human efficacy. For such diseases, a 
drug candidate is tested in an animal model. The results of the studies are submitted to the FDA as a part of the Investigational New 
Drug application (IND) which is filed to comply with FDA regulations prior to commencement of human clinical testing. For other 
diseases for which no appropriately predictive animal model exists, no such results can be filed. For several of the Company's drug 
candidates, no appropriately predictive model exists. As a result, no IN VIVO evidence of efficacy would be available until such 
compounds progress to human clinical trials. 

Clinical trials are typically conducted in three sequential phases, although the phases may overlap. In Phase I, which frequently begins 
with the initial introduction of the drug into healthy human subjects prior to introduction into patients, the compound will be tested for 
safety, dosage tolerance, absorption, bioavailability, biodistribution, metabolism, excretion, clinical pharmacology and, if possible, for 
early information on effectiveness. Phase II typically involves 

Page 19 

studies in a small sample of the intended patient population to assess the efficacy of the drug for a specific indication, to determine 
dose tolerance and the optimal dose range and to gather additional information relating to safety and potential adverse effects. Phase 
III trials are undertaken to further evaluate clinical safety and efficacy in an expanded patient population at geographically dispersed 
study sites, to determine the overall risk-benefit ratio of the drug and to provide an adequate basis for physician labeling. Each trial is 
conducted in accordance with certain standards under protocols that detail the objectives of the study, the parameters to be used to 
monitor safety and the efficacy criteria to be evaluated. Each protocol must be submitted to the FDA as part of the IND. Further, each 
clinical study must be evaluated by an independent Institutional Review Board at the institution at which the study will be conducted. 
The Institutional Review Board will consider, among other things, ethical factors, the safety of human subjects and the possible 
liability of the institution. 

Data from preclinical testing and clinical trials are submitted to the FDA in a New Drug Application (NDA) for marketing approval. 
The process of completing clinical testing and obtaining FDA approval for a new drug is likely to take a number of years and require 
the expenditure of substantial resources. Preparing an NDA involves considerable data collection, verification, analysis and expense, 
and there can be no assurance that approval will be granted on a timely basis, if at all. The approval process is affected by a number of 
factors, including the severity of the disease, the availability of alternative treatments and the risks and benefits demonstrated in 
clinical trials. The FDA may deny an NDA if applicable regulatory criteria are not satisfied or may require additional testing or 
information. Among the conditions for marketing approval is the requirement that the prospective manufacturer's quality control and 
manufacturing procedures conform to the FDA's cGMP regulations, which must be followed at all times. In complying with standards 
set forth in these regulations, manufacturers must continue to expend time, monies and effort in the area of production and quality 
control to ensure full technical compliance. Manufacturing establishments, both foreign and domestic, also are subject to inspections 
by or under the authority of the FDA and by or under the authority of other federal, state or local agencies. 

Even after initial FDA approval has been obtained, further studies, including post-marketing studies, may be required to provide 
additional data on safety and will be required to gain approval for the use of a product as a treatment for clinical indications other than 
those for which the product was initially tested. Also, the FDA will require post-marketing reporting to monitor the side effects of the 
drug. Results of post-marketing programs may limit or expand further marketing of the products. Further, if there are any 
modifications to the drug, including changes in indication, manufacturing process, labeling or manufacturing facilities, an NDA 
supplement may be required to be submitted to the FDA. 

The Orphan Drug Act provides incentives to drug manufacturers to develop and manufacture drugs for the treatment of diseases or

conditions that affect fewer than 200,000 individuals in the United States. Orphan drug status can also be sought for diseases or 
conditions that affect more than 200,000 individuals in the United States if the sponsor does not realistically anticipate its product 
becoming profitable from sales in the United States. Under the Orphan Drug Act, a manufacturer of a designated orphan product can 
seek tax benefits, and the holder of the first FDA approval of a designated orphan product will be granted a seven-year period of 
marketing exclusivity for that product for the orphan indication. While the marketing exclusivity of an orphan drug would prevent 
other sponsors from obtaining approval of the same compound for the same indication, it would not prevent other types of drugs from 
being approved for the same use. The Company may apply for orphan drug status for certain indications of MDR in cancer. 

Under the Drug Price Competition and Patent Term Restoration Act of 1984, a sponsor may be granted marketing exclusivity for a 
period of time following FDA approval of certain drug applications if FDA approval is received before the expiration of the patent's 
original term. This 

Page 20 
marketing exclusivity would prevent a third party from obtaining FDA approval for a similar or identical drug through an Abbreviated 
New Drug Application, which is the application form typically used by manufacturers seeking approval of a generic drug. The statute 
also allows a patent owner to extend the term of the patent for a period equal to one-half the period of time elapsed between the filing 
of an IND and the filing of the corresponding NDA plus the period of time between the filing of the NDA and FDA approval. The 
Company intends to seek the benefits of this statute, but there can be no assurance that the Company will be able to obtain any such 
benefits. 

Whether or not FDA approval has been obtained, approval of a drug product by regulatory authorities in foreign countries must be 
obtained prior to the commencement of commercial sales of the product in such countries. Historically, the requirements governing the 
conduct of clinical trials and product approvals, and the time required for approval, have varied widely from country to country. 

In addition to the statutes and regulations described above, the Company is also subject to regulation under the Occupational Safety 
and Health Act, the Environmental Protection Act, the Toxic Substances Control Act, the Resource Conservation and Recovery Act 
and other present and potential future federal, state and local regulations.

addition to its Scientific Advisory Board, Vertex has established consulting relationships with a number of scientific and medical 
experts who advise the Company on a project-specific basis. 

Page 23 
RISK FACTORS 

The following factors, among others, could cause actual results to differ materially from those contained in forward-looking statements 
in this Report or presented elsewhere by Vertex. 

   2002.  EDGAR Online, Inc.

Market Acceptance of Agenerase Cannot Yet Be Determined 

Agenerase is currently awaiting marketing approval by regulatory authorities, and it is too early to predict whether the product will be 
successful in the market. Four other HIV protease inhibitors are on the market, as well as a number of other products for the treatment 
of HIV infection and AIDS. In addition, numerous other drugs are still in development by the Company's competitors, which may have 
more efficacy, fewer side effects, easier administration and/or lower costs. To date, HIV has been shown to develop resistance to 
antiviral drugs, including currently marketed HIV protease inhibitors. There can be no assurance that such disease resistance or other 
factors will not limit the efficacy of Agenerase. Although Vertex will co-promote Agenerase, most of the marketing effort and all of 
the sales effort will be made by Glaxo Wellcome, and Vertex will have little control over the success of those efforts. 

SUCCESSFUL DEVELOPMENT OF PIPELINE CANNOT BE PREDICTED 

The products that the Company is pursuing will require extensive additional development, testing and investment, as well as regulatory 
approvals, prior to commercialization. No assurance can be given that the Company's product development efforts will be successful, 
that required regulatory approvals will be obtained or that any products, if introduced, will be commercially successful. The results of 
preclinical and initial clinical trials of products under development by the Company are not necessarily predictive of results that will 
be obtained from large-scale clinical testing, and there can be no assurance that clinical trials of products under development will 
demonstrate the safety and efficacy of such products or will result in a marketable product. The administration alone or in combination 
with other drugs of any product developed by the Company may produce undesirable side effects in humans. The failure to 
demonstrate adequately the safety and efficacy of a therapeutic drug under development could delay or prevent regulatory approval of 
the product and could have a material adverse effect on the Company. In addition, the FDA may require additional clinical trials, 
which could result in increased costs and significant development delays. Commercial formulation and manufacturing processes have 
yet to be developed for the Company's drug candidates other than Agenerase. The Company or its collaborators may encounter 
difficulties in their manufacturing process development and formulation activities that could result in delays in clinical trials, 
regulatory submissions and commercialization of its products, or cause negative financial and competitive consequences. 

CLINICAL TRIAL TIMING MAY BE SUBJECT TO DELAYS 

The rate of completion of clinical trials of the Company's products is dependent upon, among other factors, the rate of patient accrual. 
Patient accrual is a function of many factors, including the size of the patient population, the proximity of patients to clinical sites, the 
eligibility criteria for the trial and the availability of clinical trial material. Delays in planned patient enrollment in clinical trials may 
result in increased costs, program delays or both, which could have a material adverse effect on the Company. There can be no 
assurance that if clinical trials are completed the Company will be able to submit an NDA or that any such application will be reviewed 
and approved by the FDA in a timely manner, if at all. 

Page 24 
VERTEX IS DEPENDENT ON COLLABORATIVE PARTNERS 

The Company is engaged in research and development collaborations, pursuant to which its partners have agreed to fund portions of 
the Company's research and development programs and/or to conduct certain research and development relating to specified products, 
in exchange for certain technology, product and marketing rights relating to those products. Some of the Company's current corporate 
partners have certain rights to control the planning and execution of product development and clinical programs, and there can be no 
assurance that such corporate partners' rights to control aspects of such programs will not impede the Company's ability to conduct 
such programs in accordance with the schedules and in the manner currently contemplated by the Company for such programs. If any 
of the Company's corporate collaborators were to terminate its relationship with Vertex, it could have a material adverse effect on the 
Company's ability to fund related and other programs and to develop, manufacture and market any products that may have resulted 
from such collaboration. The Company expects to seek additional collaborative arrangements to develop and commercialize its 
products in the future. There can be no assurance that the Company will be able to establish acceptable collaborative arrangements in 
the future or that such collaborative arrangements will be successful. 

THE TECHNOLOGIES USED BY VERTEX ARE RAPIDLY CHANGING 

The Company is engaged in pharmaceutical fields characterized by extensive research efforts, rapid technological progress and intense 
competition. Further, the Company believes that interest in the application of structure-based drug design and related technologies may 
continue and may accelerate as the technologies become more widely understood. Businesses, academic institutions, governmental 
agencies and other public and private research organizations are conducting research to develop technologies that may compete with 
those used by the Company. It is possible that the Company's competitors could acquire or develop technologies that would render the 
Company's technology obsolete or noncompetitive. 

   2002.  EDGAR Online, Inc.

VERTEX FACES SUBSTANTIAL COMPETITION 

There are many public and private companies, including pharmaceutical companies, chemical companies and biotechnology 
companies, engaged in developing products for the human therapeutic applications targeted by Vertex. The Company is aware of 
efforts by others to develop products in each of the areas in which the Company has products in development. In addition, there can be 
no assurance that the Company's products in development will be able to compete effectively with products which are currently on the 
market. In order for the Company to compete successfully in these areas, it must demonstrate improved safety, efficacy, ease of 
manufacturing and market acceptance over its competitors, who have received regulatory approval and are currently marketing. Many 
of the Company's competitors have substantially greater financial, technical and human resources than those of the Company. In 
addition, many of the Company's competitors have significantly greater experience than the Company in conducting preclinical testing 
and human clinical trials of new pharmaceutical products, and in obtaining FDA and other regulatory approvals of products. 
Accordingly, certain of the Company's competitors may succeed in obtaining regulatory approval for products more rapidly than the 
Company. If the Company obtains regulatory approval and commences commercial sales of its products, it will also compete with 
respect to manufacturing efficiency and sales and marketing capabilities, areas in which it currently has no experience. 

VERTEX RELIES ON THIRD PARTY MANUFACTURERS 

The Company's ability to conduct clinical trials and its ability to commercialize its potential products will depend, in part, on its ability 
to manufacture its products on a large scale, either directly or through third parties, at a competitive cost and in accordance with FDA 
and other 

Page 25 

regulatory requirements. The Company currently does not have the capacity to manufacture drugs in large-scale quanties and is 
dependent on third party manufacturers or collaborative partners for the production of its compounds for preclinical research, clinical 
trial purposes and commercial production. In the event that the Company is unable to obtain contract manufacturing, or obtain such 
manufacturing on commercially reasonable terms, it may not be able to conduct or complete clinical trials or commercialize its 
products as planned. The Company has no experience in manufacturing pharmaceutical or other products, and there can be no 
assurance that the Company will successfully develop such capabilities. Some of the Company's current corporate partners have 
certain manufacturing rights with respect to the Company's products under development, and there can be no assurance that such 
corporate partners' manufacturing rights will not impede the Company's ability to conduct the development programs and 
commercialize any resulting products in accordance with the schedules and in the manner currently contemplated by the Company. 

THE REGULATORY APPROVAL PROCESS IS SUBJECT TO UNCERTAINTIES 

The FDA and comparable agencies in foreign countries impose substantial requirements on the introduction of therapeutic 
pharmaceutical products through lengthy and detailed laboratory and clinical testing procedures, sampling activities and other costly 
and time-consuming procedures. Satisfaction of these requirements typically takes several years or longer and may vary substantially 
based upon the type, complexity and novelty of the pharmaceutical product. Data obtained from preclinical and clinical activities are 
susceptible to varying interpretations, which could delay, limit or prevent regulatory approval. In addition, delays or rejections may be 
encountered based on changes in, or additions to, regulatory policies for drug approval during the period of product development and 
regulatory review. The effect of government regulation may be to delay or prevent the commencement of clinical trials or marketing of 
Company products, if any are developed and submitted for approval, for a considerable period of time, to impose costly procedures 
upon the Company's activities and to provide a competitive advantage to larger companies or companies more experienced in 
regulatory affairs that compete with the Company. Moreover, even if approval is granted, such approval may entail limitations on the 
indicated uses for which a compound may be marketed. 

THE SCOPE OF PATENT PROTECTION IS UNCERTAIN 

The Company's success will depend, in part, on its ability to obtain United States and foreign patent protection for its products and 
their uses, to preserve its trade secrets and to operate without infringing the proprietary rights of third parties. There can be no 
assurance that patents will issue from any of the Company's pending or future patent applications. Legal standards relating to the 
validity of patents and the proper scope of their claims in the biopharmaceutical field are still evolving, and there is no consistent law 
or policy regarding the valid breadth of claims in biopharmaceutical patents or the effect of prior art on them. If the Company is unable 
to obtain adequate patent protection, its ability to prevent competitors from making, using and selling competing products will be 
limited. Furthermore, the Company's activities may infringe the claims of the patents held by third parties. Defense and prosecution of 
patent claims, as well as participation in interference proceedings, can be expensive and time-consuming, even in those instances in 
which the outcome is favorable to the Company. If the outcome of any such litigation or proceeding were adverse, the Company could 
be subject to significant liabilities to third parties, could be required to obtain licenses from third parties or could be required to cease 
sales of the affected products, any of which could have a material adverse effect on the Company.

Page 26 
VERTEX WILL CONTINUE TO HAVE SIGNIFICANT FUTURE CAPITAL NEEDS; AVAILABILITY OF ADDITIONAL 
FUNDING IS UNCERTAIN 

The Company expects to incur substantial research and development and related supporting expenses as it designs and develops 
existing and future compounds and undertakes clinical trials of potential drugs resulting from such compounds. The Company also 
expects to incur substantial administrative and commercialization expenditures in the future and substantial expenses related to the 
filing, prosecution, defense and enforcement of patent and other intellectual property claims. The Company anticipates that it will 
finance these substantial cash needs with Agenerase royalty revenue, its existing cash reserves, together with interest earned thereon, 
future payments under its collaborative agreements, facilities and equipment financing and additional collaborative agreements. To the 
extent that funds from these sources are not sufficient to fund the Company's activities, it will be necessary to raise additional funds 
through public offerings or private placements of debt or equity securities or other methods of financing. Any equity financings could 
result in dilution to the Company's then existing stockholders. Any debt financing, if available at all, may be on terms which, among 
other things, restrict the Company's ability to pay dividends (although the Company does not intend to pay dividends for the 
foreseeable future). If adequate funds are not available, the Company may be required to curtail significantly or discontinue one or 
more of its research, drug discovery or development programs, including clinical trials, or attempt to obtain funds through 
arrangements with collaborative partners or others that may require the Company to relinquish rights to certain of its technologies or 
products in research or development. No assurance can be given that additional financing will be available on acceptable terms, if at 
all. 

THIRD PARTY PHARMACEUTICAL REIMBURSEMENT POLICIES MAY AFFECT PRODUCT PRICING 

The success of the Company's products in the United States and other significant markets will depend, in part, upon the extent to which 
a consumer will be able to obtain reimbursement for the cost of such products from government health administration authorities, 
third-party payors and other organizations. Significant uncertainty exists as to the reimbursement status of newly approved therapeutic 
products. Even if a product is approved for marketing, there can be no assurance that adequate reimbursement will be available. The 
Company is unable to predict what additional legislation or regulation relating to the health care industry or third-party coverage and 
reimbursement may be enacted in the future or what effect the legislation or regulation would have on the Company's business. Failure 
to obtain reimbursement could have a material adverse effect on the Company. 

THE COMPANY LACKS SALES AND MARKETING EXPERIENCE 

The Company currently has little experience in marketing and no experience selling pharmaceutical products. The Company must 
either develop a marketing and sales force or enter into arrangements with third parties to market and sell any of its product candidates 
which are approved by the FDA. In the territories where the Company retains marketing and co-promotion rights, there can be no 
assurance that the Company will successfully develop its own sales and marketing experience or that it will be able to enter into 
marketing and sales agreements with others on acceptable terms, if at all. If the Company develops its own marketing and sales 
capability, it will compete with other companies that currently have experienced and well-funded marketing and sales operations. To 
the extent that the Company has or enters into co-promotion or other sales and marketing arrangements with other companies, any 
revenues to be received by the Company will be dependent on the efforts of others, and there can be no assurance that such efforts will 
be successful. 

THERE IS A RISK OF PRODUCT LIABILITY 

Page 27 

The Company's business will expose it to potential product liability risks that are inherent in the testing, manufacturing and marketing 
of pharmaceutical products. The use of the Company's products in clinical trials also exposes the Company to the possibility of 
product liability claims and possible adverse publicity. These risks will increase to the extent the Company's products receive 
regulatory approval and are commercialized. There can be no assurance that the Company will be able to maintain its existing levels of 
product liability insurance or be able to obtain or maintain such additional insurance as it may need in the future on acceptable terms. 
Nor can there be any assurance that the Company's existing insurance or any such additional insurance will provide adequate coverage 
against potential liabilities. 

SHARE PRICE MAY FLUCTUATE BASED ON FACTORS BEYOND VERTEX'S CONTROL 

Market prices for securities of companies such as Vertex are highly volatile, and the market for the securities of such companies, 
including the Common Stock of the Company, has from time to time experienced significant price and volume fluctuations that are 
unrelated to the operating performance of these particular companies. Factors such as announcements of results of clinical trials, 

   2002.  EDGAR Online, Inc.

technological innovations or new products by Vertex or its competitors, government regulatory action, public concern as to the safety 
of products developed by the Company or others, patent or proprietary rights developments and market conditions for pharmaceutical 
and biotechnology stocks, in general, could have a significant adverse effect on the future market price of the Company's common 
stock. 

VERTEX HAS ANTI-TAKEOVER PROVISIONS THAT MAY DISCOURAGE CHANGE IN CONTROL 

The Company's charter and By-law provisions and the Company's Stockholder Rights Plan may discourage certain types of 
transactions involving an actual or potential change in control of the Company which might be beneficial to the Company or its 
stockholders. The Company's charter provides for staggered terms for the members of the Board of Directors. The Company's By-laws 
grant the Directors a right to adjourn annual meetings of stockholders, and certain provisions of the By-laws may be amended only 
with an 80% stockholder vote. Pursuant to the Company's Stockholder Rights Plan, each share of Common Stock has an associated 
preferred share purchase right (a "Right"). The Rights will not trade separately from the Common Stock until, and are exercisable only 
upon, the acquisition or the potential acquisition through tender offer by a person or group of 15% or more of the outstanding 
Common Stock. Shares of any class or series of preferred stock may be issued by the Company in the future without stockholder 
approval and upon such terms as the Board of Directors may determine. The rights of the holders of Common Stock will be subject to, 
and may be adversely affected by, the rights of the holders of any class or series of preferred stock that may be issued in the future. 

ITEM 2. PROPERTIES 

The Company leases an aggregate of approximately 134,000 square feet of laboratory and office space in seven facilities at in 
Cambridge, Massachusetts. The leases have expiration dates ranging from December 2000 to 2009. The Company has the option to 
extend the lease for the Company's headquarters facility at 130 Waverly Street, Cambridge, for up to two additional terms, ending in 
2015. 

During 1998, Vertex opened a research and development facility in the U.K. of approximately 7,000 square feet of laboratory and 
office space located in Swindon under a lease expiring in August 2000. The Company has the right to terminate this lease at any time 
after June 1999. The Company has also leased approximately 24,000 square feet of laboratory and office 

Page 28 
space in Milton Park under a lease expiring in 2013, with a right of early termination in 2008. Upon completion of construction of the 
Milton Park facility, expected by the third quarter of 1999, the Company will consolidate its U.K. business and research and 
development activities from Ascot and Swindon to Milton Park. 

The Company believes its facilities are adequate for its current needs. The Company believes it can obtain additional space on 
commercially reasonable terms. 

ITEM 3. LEGAL PROCEEDINGS 

Chiron Corporation ("Chiron") filed suit on July 30, 1998 against the Company and Eli Lilly and Company in the United States 
District Court for the Northern District of California, alleging infringement by the defendants of various U.S. patents issued to Chiron. 
The infringement action relates to research activities by the defendants in the hepatitis C viral protease field and the alleged use of 
inventions claimed by Chiron in connection with that research and development. Chiron has requested damages in an unspecified 
amount, as well as an order permanently enjoining the defendants from unlicensed use of Chiron inventions. While the final outcome 
of these actions cannot be determined, the Company believes that the plaintiff's claims are without merit and intends to defend the 
actions vigorously. 

ITEM 4. SUBMISSION OF MATTERS TO SECURITY HOLDERS 

There were no matters submitted to a vote of security holders during the fourth quarter of the fiscal year ended December 31, 1998.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF 
OPERATIONS 

Page 30 

THIS DISCUSSION CONTAINS FORWARD-LOOKING STATEMENTS WHICH ARE SUBJECT TO CERTAIN RISKS AND 
UNCERTAINTIES THAT CAN CAUSE ACTUAL RESULTS TO DIFFER MATERIALLY FROM THOSE DESCRIBED. 
FACTORS THAT MAY CAUSE SUCH DIFFERENCES INCLUDE BUT ARE NOT LIMITED TO THOSE DESCRIBED IN THE 
SECTION ENTITLED "RISK FACTORS." READERS ARE CAUTIONED NOT TO PLACE UNDUE RELIANCE ON THESE 
FORWARD-LOOKING STATEMENTS WHICH SPEAK ONLY AS OF THE DATE HEREOF. THE COMPANY UNDERTAKES 
NO OBLIGATION TO PUBLICLY UPDATE OR REVISE THESE FORWARD-LOOKING STATEMENTS TO REFLECT 
EVENTS OR CIRCUMSTANCES AFTER THE DATE HEREOF. 

The Company is engaged in the discovery, development and commercialization of novel, small molecule pharmaceuticals for the 
treatment of major diseases for which there are currently limited or no effective treatments. The Company is a leader in the use of 
structure-based drug design, an approach to drug discovery that integrates advanced biology, biophysics, chemistry and information 
technologies. The Company is conducting research and development programs to develop pharmaceuticals for the treatment of viral 
diseases, multidrug resistance in cancer, autoimmune and inflammatory diseases and neurodegenerative disorders. 

To date, the Company has not received any material revenues from the sale of pharmaceutical products. A New Drug Application 
("NDA") was submitted in October 1998 for the Company's lead product, Agenerase-TM- (amprenavir) for the treatment of HIV 
infection. Glaxo Wellcome plc ("Glaxo Wellcome"), Vertex's partner, has also submitted applications for market approval to Canadian 
and European regulatory agencies. Assuming the NDA is approved, the Company will receive a royalty on sales of Agenerase from 
Glaxo Wellcome. The Company has incurred operating losses since its inception and expects to incur a loss in 1999. The Company 
believes that operating losses may continue beyond 1999, even if significant royalties are realized on Agenerase-TM- sales, because 
the Company is planning to make significant investments in research and development for its other potential products. The Company 
expects that losses will fluctuate from quarter to quarter and that such fluctuations may be substantial. 

RESULTS OF OPERATIONS 

YEAR ENDED DECEMBER 31, 1998 COMPARED WITH YEAR ENDED DECEMBER 31, 1997. 

The Company's total revenues were $44,398,000 in 1998 as compared to $43,799,000 in 1997. In 1998, revenues consisted of 
$27,939,000 under the Company's collaborative agreements, $15,343,000 in investment income and $1,116,000 in government grants 
and other income. Collaborative revenue in 1998 included a $6,000,000 payment from Schering AG, Germany ("Schering AG") 
associated with the signing of a collaborative agreement for the Company's neurophilin ligand program and $4,000,000 of research 
funding under that agreement, a $2,000,000 milestone payment from Kissei Pharmaceutical Co., Ltd. ("Kissei") for the acceptance of 
VX-745 as the lead development candidate for the Company's p38 MAP kinase program, and a $3,000,000 milestone payment from 
Glaxo Wellcome for the NDA filing for Agenerase. Other collaborative revenue in 1998 included $3,738,000 from Kissei, $3,457,000 
from Glaxo Wellcome, $5,193,000 from Eli Lilly and Company ("Lilly") and $551,000 from others. Research funding requirements 
under the Glaxo Wellcome agreement ended on December 31, 1998, although Glaxo Wellcome continues to have certain development 
funding obligations. In 1997, revenues consisted of $27,703,000 under the Company's collaborative agreements, $13,873,000 in 
investment income, and $2,223,000 in government grants and other income. Revenue from collaborative agreements in 1997 consisted 
of $3,275,000 from Glaxo Wellcome, $8,660,000 from Hoechst Marion Roussel ("HMR"), $9,810,000 from Kissei, $5,694,000 from 

Lilly and $264,000 from others.

Total costs and expenses increased to $77,484,000 in 1998 from $63,630,000 in 1997. Research and development expenses increased 
to $58,668,000 in 1998 from $51,624,000 in 1997. The Company increased research staffing, including opening a research site in the 
U.K., to fully staff a higher number of discovery programs. In addition, the Company expanded its development infrastructure. General 
and administrative expenses increased in 1998 to $18,135,000 from $11,430,000 in 1997 primarily as a result of headcount growth to 
handle the administrative requirements of the Company's growing research and development operation, legal expenses associated with 
expansion of the Company's intellectual property position and marketing expenses associated with the anticipated launch of Agenerase 
and the Company's co-promotion preparations. Interest expense increased in 1998 to $681,000 from $576,000 in 1997 due to higher 
levels of equipment financing during 1998. 

The Company recorded a net loss of $33,086,000 or $1.31 per share in 1998 compared to a net loss of $19,831,000 or $0.82 per share 
in 1997. 

YEAR ENDED DECEMBER 31, 1997 COMPARED WITH YEAR ENDED DECEMBER 31, 1996. 

The Company's total revenues increased to $43,799,000 in 1997 from $18,598,000 in 1996. In 1997, revenues consisted of 
$27,703,000 under the Company's collaborative agreements, $13,873,000 in investment income, and $2,223,000 in government grants 
and other income. The principal reasons for the increase in revenue in 1997 were the commencement of new collaborations with Lilly 
on the Company's hepatitis C protease program and with Kissei on the Company's p38 MAP kinase program, in addition to greater 
investment income from higher levels of cash and investments. The 1997 collaborations with Lilly and Kissei included payments of 
$3,000,000 and $4,000,000, respectively, and research funding of $2,694,000 and $1,500,000, respectively. Other collaborative 
revenue in 1997 included $4,310,000 from Kissei, $8,660,000 from HMR, which included a $3,000,000 milestone payment, 
$3,275,000 from Glaxo Wellcome, and $264,000 from others. Research funding requirements under the HMR agreement ended on 
December 31, 1997, although HMR continues to have certain development funding obligations. In 1996, revenues consisted of 
$12,013,000 under the Company's collaborative agreements, $5,257,000 in investment income and $1,328,000 in government grants 
and other income. Revenue from collaborative agreements consisted of $6,289,000 from Glaxo Wellcome, $4,196,000 from HMR, 
$692,000 from Kissei and $836,000 from others. 

The Company's total costs and expenses increased to $63,630,000 in 1997 from $58,603,000 in 1996. In 1996, the Company paid 
$15,000,000 to obtain a non-exclusive, world-wide license under certain G.D. Searle & Co. ("Searle") patent applications claiming 
HIV protease inhibitors. Research and development expenses increased to $51,624,000 in 1997 from $35,212,000 in 1996 principally 
due to the commencement of preclinical development activities for drug candidates in the ICE and IMPDH programs as well as the 
continued expansion of the Company's core scientific staff. In addition, general and administrative expenses increased to $11,430,000 
in 1997 from $7,929,000 in 1996. The increase in general and administrative expense principally reflects the impact of personnel 
additions, an increase in legal expenses related to patent activity and an increase in marketing activities. Interest expense increased to 
$576,000 in 1997 from $462,000 in 1996 due to higher levels of equipment lease financing during the year. 

The Company recorded a net loss of $19,831,000 or $0.82 per share in 1997 compared to a net loss of $40,005,000 or $2.13 per share 
in 1996. The lower loss per share reflects not only a lower aggregate loss but also an increase in average common shares outstanding 
from 18,798,000 in 1996 to 24,264,000 in 1997 due to two Common Stock offerings in August 1996 and March 1997. 

LIQUIDITY AND CAPITAL RESOURCES 

Page 32 

The Company's operations have been funded principally through strategic collaborative agreements, public offerings and private 
placements of the Company's equity securities, equipment financing, government grants and investment income. Assuming Agenerase 
is approved by the FDA, the Company will begin receiving product royalty revenue in 1999. The Company has been expanding its 
operations in order to increase and advance the number of potential products in its research and development pipeline. Consequently, 
the Company expects to incur increased research and development and related supporting expenses and is likely to continue 
experiencing losses on a quarterly and annual basis. The Company also expects to incur substantial administrative and 
commercialization expenditures in the future and additional expenses related to the filing, prosecution, defense and enforcement of 
patent and other intellectual property rights. 

The Company expects to finance these substantial cash needs with expected royalty revenue from Agenerase, its existing cash and 
investments of approximately $246,000,000 at December 31, 1998, together with investment income earned thereon, future payments 
under its existing collaborative agreements, and facilities and equipment financing. To the extent that funds from these sources are not 
sufficient to fund the Company's activities, it will be necessary to raise additional funds through public offerings or private placements 
of securities, or new research collaborations for new or existing projects or other methods of financing. There can be no assurance that 
such financing will be available on acceptable terms, if at all. 

   2002.  EDGAR Online, Inc.

The Company's aggregate cash and investments decreased by $34,019,000 during 1998 to $245,652,000 at December 31, 1998. Cash 
used by operations, principally to fund research and development activities, was $31,055,000 during the same period. The Company 
also expended $7,901,000 during this period to acquire property and equipment, principally for research equipment and facilities. 
During 1998, the Company entered into equipment financing arrangements in the aggregate amount of $4,085,000 and repaid 
$2,716,000 of its lease obligations. 

In addition to the expansion of the research and development activities in the U.S., the Company expanded its U.K. operations to 
include a research site during 1998. The Company expects that, in general, research and development as well as general and 
administrative expenses will continue to increase as the Company starts new research projects, advances current clinical and 
preclinical candidates, and expands its marketing and business development activities. 

During 1998, the Company and Schering AG entered into a collaborative agreement to research, develop and commercialize novel, 
orally active neurophilin ligand compounds to promote nerve regeneration for the treatment of a number of neurological diseases. 
Under the terms of the agreement, Schering AG will pay the Company up to $88,000,000 composed of a $6,000,000 license payment 
paid in September 1998, $22,000,000 of product research funding over five years and potentially $60,000,000 of development and 
commercialization milestone payments. 

At December 31, 1998, the Company leased approximately 134,000 square feet of office and research space in the U.S. and 31,000 
square feet in the U.K. These leases have terms ranging from 3 to 10 years. In addition, the Company's liability for capitalized 
equipment lease obligations and other equipment financing totaled approximately $10 million at December 31, 1998. 

YEAR 2000 

The Company has completed its evaluation of its business critical information technology systems ("IT Systems") and has determined 
the actions necessary in order to ensure that such IT Systems will be able to function without disruption with respect to the application 
of dating systems in the Year 2000. The Company has begun to upgrade, replace and test certain of its IT 

Page 33 
Systems based on the results of that evaluation. Evaluation of embedded systems in the Company's non-computer equipment ("Non-IT 
Systems") for Year 2000 compliance is under way but has not been completed. 

In addition to risks associated with the Company's own computer systems and equipment, the Company has relationships with, and is 
to varying degrees dependent upon, a number of third parties that provide goods, services and information to the Company. These 
include contract manufacturers, suppliers, licensees and licensors, vendors, research partners and financial institutions, whose systems 
and equipment are outside the control of the Company. If certain of these third parties experience failures in their computer systems or 
equipment due to Year 2000 non-compliance, it could affect the Company's ability to engage in normal business activities. The 
Company intends to contact its significant vendors and partners to ascertain their Year 2000 compliance and to determine the extent to 
which the Company is vulnerable to their non-compliance, if any. 

The Company expects to complete its internal evaluation and remediation efforts and its assessment of third party compliance and 
contingency plans by mid-1999. However, there can be no assurance that these evaluations and any required remedial actions will be 
able to be completed on a timely basis. The Company believes that its IT Systems and Non-IT Systems are either already Year 2000 
compliant or will be so prior to the Year 2000. The Company estimates the cost of making its IT  systems and Non-IT systems Year 
2000 complaint will be approximately $200,000. There can be no assurance, however, that the Company will not experience 
unexpected costs in achieving full Year 2000 compliance, which could result in a material adverse effect on the Company's future 
results of operations. The Company believes that it will be able to locate alternate sources for any critical goods or services provided 
by non-compliant third parties, if any. However, the Company may not be able to timely develop or implement contingency plans to 
address those business critical systems and third party relationships which may not be Year 2000 compliant. 

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK 

The Company owns financial instruments that are sensitive to market risks as part of its investment portfolio. The investment portfolio 
is used to preserve the Company's capital until it is required to fund operations, including the Company's research and development 
activities. None of these market-risk sensitive instruments are held for trading purposes. The Company does not own derivative 
financial instruments in its investment portfolio. 

INTEREST RATE RISK 

   2002.  EDGAR Online, Inc.

The Company invests its cash in a variety of financial instruments, principally securities issued by the U.S. Government and its 
agencies, investment grade corporate and money market instruments. These investments are denominated in U.S. dollars. These bonds 
are subject to interest rate risk, and could decline in value if interest rates fluctuate. The Company's investment portfolio includes only 
marketable securities with active secondary or resale markets to help ensure portfolio liquidity and the Company has implemented 
guidelines limiting the duration of investments. Due to the conservative nature of these instruments, the Company does not believe that 
it has a material exposure to interest rate risk.

Report of Independent Accountants 

In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of operations, of stockholders' 
equity and of cash flows present fairly, in all material respects, the financial position of Vertex Pharmaceuticals Incorporated and its 
subsidiaries at December 31, 1998 and 1997, and the results of their operations and their cash flows for each of the three years in the 
period ended December 31, 1998 in conformity with generally accepted accounting principles. These financial statements are the 
responsibility of the Company's management; our responsibility is to express an opinion on these financial statements based on our 
audits. We conducted our audits of these statements in accordance with generally accepted auditing standards which require that we 
plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An 
audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the 
accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. 
We believe that our audits provide a reasonable basis for the opinion expressed above.

VERTEX PHARMACEUTICALS INCORPORATED 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

Page F-6 

A. THE COMPANY 

Vertex Pharmaceuticals Incorporated ("Vertex" or the "Company") uses a range of drug discovery technologies to identify, design and 
develop novel, orally deliverable compounds that have the potential to treat major human diseases. As of December 31, 1998, the 
Company has not received any material revenues from the sale of pharmaceutical products. The Company's revenues during 1998, 
1997 and 1996 principally resulted from research support payments from corporate partners and investment income. The Company 
expects to incur an operating loss in 1999 and potentially beyond 1999, as a result of expenditures for its research and development 
programs. 

The consolidated financial statements include the accounts of the Company and the following subsidiaries: Altus Biologics Inc. 
("Altus"), Vertex Securities Corp. and Vertex Pharmaceuticals (Europe) Limited. All material intercompany transactions are 
eliminated. Minority interests are carried at cost. 

The Company is subject to risks common to companies in the biotechnology industry including, but not limited to, rapid technological 
change and competition, dependence on key personnel, uncertainty of protection of proprietary technology, clinical trial uncertainty, 
dependence on collaborative partners, share price volatility, the possible need to obtain additional funding, uncertainties relating to 
pharmaceutical pricing and reimbursement, limited experience in manufacturing and sales and marketing, potential product liability 
and the need for compliance with government regulations. 

B. ACCOUNTING POLICIES 

   2002.  EDGAR Online, Inc.

USE OF ESTIMATES 

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make 
certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and 
liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reported period. Actual 
results could differ from those estimates. 

CASH AND CASH EQUIVALENTS 

Cash equivalents, which are money market funds and debt securities, are valued at cost plus accrued interest. The Company considers 
all highly liquid investments with original maturities of three months or less at the date of purchase to be cash equivalents. Changes in 
cash and cash equivalents may be affected by shifts in investment portfolio maturities as well as by actual cash receipts and 
disbursements. Financial instruments which potentially subject the Company to concentration of credit risk consist principally of 
money market funds and marketable securities. The Company places these investments in highly rated financial institutions, and, by 
policy, limits the amounts of credit exposure to any one financial institution. These amounts at times may exceed federally insured 
limits. The Company has not experienced any losses in such accounts and does not believe it is exposed to any significant credit risk 
on these funds. 

INVESTMENTS 

Investments consist of marketable securities which are classified as available for sale. Investments are stated at fair value with 
unrealized gains and losses included as a component of accumulated 

other comprehensive income (loss) until realized. The fair value of these securities is based on quoted market prices. Realized gains 
and losses are determined on the specific identification method and are included in investment income. 

Page F-7 

PROPERTY AND EQUIPMENT 

Property and equipment are recorded at cost. Depreciation and amortization are provided using the straight-line method over the lesser 
of the lease terms or the estimated useful lives of the related assets, generally four or five years for equipment and furniture and three 
years for purchased software. Leasehold improvements are amortized over the life of leases. When assets are retired or otherwise 
disposed of, the assets and related allowances for depreciation and amortization are eliminated from the accounts and any resulting 
gain or loss is reflected in income (loss). 

REVENUE RECOGNITION 

Revenue under research and development arrangements is recognized as earned under the terms of the respective agreements. License 
payments are recorded as revenue when contractual obligations have been met. Product research funding is recorded as revenue, 
generally on a quarterly basis, as research effort is incurred. Deferred revenue arises from payments received which have not yet been 
earned under research and development arrangements. The Company recognizes milestone payments when the milestones are 
achieved. 

RESEARCH AND DEVELOPMENT 

All research and development costs are expensed as incurred. 

INCOME TAXES 

Deferred tax assets and liabilities are recognized for the expected future tax consequences, using current tax rates, of temporary 
differences between the financial statement carrying amounts and the income tax bases of assets and liabilities. A valuation allowance 
is applied against any net deferred tax asset if, based on the weighted available evidence, it is more likely than not that some or all of 
the deferred tax assets will not be realized. 

BASIC AND DILUTED LOSS PER COMMON SHARE 

Basic earnings per share is based upon the weighted average number of common shares outstanding during the period. Diluted 
earnings per share is based upon the weighted average number of common shares outstanding during the period plus additional 

   2002.  EDGAR Online, Inc.

weighted average common equivalent shares outstanding during the period when the effect is not anti-dilutive. Common equivalent 
shares result from the assumed exercise of outstanding stock options, the proceeds of which are then assumed to have been used to 
repurchase outstanding stock using the treasury stock method. Common equivalent shares have not been included in the per-share 
calculations as the effect would be anti-dilutive. Potential common equivalent shares consist of 5,837,000 stock options outstanding 
with a weighted average exercise price of $22.62 as of December 31, 1998. 

SEGMENT INFORMATION 

The Company is in one business segment, the business of discovery, development and commercialization of novel, small molecule 
pharmaceuticals. The Company follows the requirements of FAS 131 "Disclosures about Segments of an Enterprise and Related 
Information."

During 1997 and 1996, the Company financed under capital lease arrangements an aggregate of $1,179,000 and $3,727,000, 
respectively, of asset cost under its master lease agreements. At the end of the lease term, the Company has the right to either return the 
equipment to the lessor or purchase the equipment for fair market value at that time. These agreements have a term of five years and 
require that the Company maintain a certain level of cash and investments. 

During 1998, the Company financed under a master debt agreement, assets with a cost of $1,574,000, $1,506,000 and $1,005,000 with 
interest rates of 7.89%, 
8.06% and 8.08%, respectively. During 1997, the Company financed under a master debt agreement, assets with a cost of $676,000 
and $1,137,000 with interest rates of 8.59% and 8.38%, respectively. The Company has certain equipment with a net book value of

$4,945,000, designated as collateral under these agreements. These agreements have a term of five years, and require that the 
Company maintain a certain level of cash and investments. The carrying value of these debt obligations approximates fair value. 

Interest paid under capital leases and debt was $681,000, $576,000 and $462,000 in 1998, 1997 and 1996, respectively.

H. INCOME TAXES 

The Company's federal statutory income tax rate for 1998, 1997 and 1996 was 34%. The Company recorded no income tax benefit for 
1998, 1997 and 1996 and recorded a full valuation allowance against net operating losses due to uncertainties related to realizability of 
these tax assets. 

Deferred tax liabilities and assets are determined based on the difference between financial statement and tax bases using enacted tax 
rates in effect for the year in which the differences are expected to reverse. The components of the deferred taxes at December 31, 
were as follows (in thousands):

                                    ---------         -------- 

For federal income tax purposes, as of December 31, 1998, the Company has net operating loss carryforwards of approximately 
$143,238,000 and $7,624,000 of tax credits, which may be used to offset future income. These net operating loss carryforwards expire 
beginning in 2005, and the tax credit carryforwards begin to expire in 2004. Approximately $22,935,000 of the net operating loss 
carryforwards and $245,000 of the tax credit carryforwards belong to Altus and can only be used to offset future income of Altus. A 
valuation allowance has been established for the full amount of the deferred tax asset since it is more likely than not that the deferred 
tax asset will not be realized. 

The amount of tax credits and net operating loss carryforwards that the Company may utilize in any one year is limited in accordance 
with Internal Revenue Code ss.382. This limitation arises whenever a cumulative change in ownership in excess of 50% occurs. A 
change of ownership has occurred which will limit the amount of net operating loss and tax credits available prior to the change. There 
may also be further changes of ownership subsequent to 1998 which may also limit the amount of net operating loss and tax credit 
utilization in a subsequent year.

STOCK OPTION PLANS 

The Company applies APB Opinion No. 25 and related interpretations in accounting for its stock-based compensation plans. However, 
pro forma disclosures as if the Company adopted the cost recognition requirements under FASB Statement No. 123 "Accounting for 
Stock-Based Compensation" ("SFAS 123") in 1998, 1997 and 1996 are presented below. Compensation expense of $91,000 and 
$66,000 was recognized during 1998 and 1997, respectively. No compensation expense was recognized for these plans in 1996. 

The Company has the 1991 Stock Option Plan (the "1991 Plan") and 1994 Stock and Option Plan (the "1994 Plan") and 1996 Stock 
and Option Plan (the "1996 Plan"). Under the 1994 Plan and the 1996 Plan, stock rights, which are either (i) incentive stock options 
when Internal Revenue Code requirements are met, (ii) non-qualified stock options ("NQSOs"), or (iii) award shares of Common 
Stock or the opportunity to make a direct purchase of shares of Common Stock ("Stock Awards"), may be granted to employees 
(including officers and directors who are employees), consultants, advisors and non-employee directors (NQSOs and stock awards 
only). Incentive stock options granted under the Plans may not be granted at a price less than the fair market value of the Common 
Stock on the date of grant. Non-qualified stock options may be granted at an exercise price established by the Compensation 
Committee of the Board of Directors, which may be less than, equal to or greater than the fair value of the Common Stock on the date 
of grant. Vesting periods, generally four or five years, are determined by the Compensation Committee. Incentive stock options 
granted under the Plans must expire not more than ten years from the date of grant. At December 31, 1998, the Company had 
2,074,000 shares of common stock available for future grant under its stock option plans.

The fair value of each option granted during 1998, 1997 and 1996 was estimated on the date of grant using the Black-Scholes 
option-pricing model with the following weighted average assumptions: (1) expected life of 5.11 years for the 1998 grants, 5.18 years 
for the 1997 grants and 5.41 years for the 1996 grants 
(2) expected volatility of 46.5% for the 1998 grants, 44.7% for the 1997 grants and 42% for the 1996 grants (3) risk-free interest rate 
of 4.86% for the 1998 grants, 5.5% for the 1997 grants and 6.30% for the 1996 grants and (4) no dividend yield.

EMPLOYEE STOCK PURCHASE PLAN 

Page F-13 

Under the Company's Employee Stock Purchase Plan, substantially all permanent employees may, through payroll withholdings, 
purchase shares of the Company's Common Stock at a price of 85% of the lesser of fair market value at the beginning or end of each 
six-month withholding period. During 1998, 38,170 shares of Common Stock at a price of $22.66 per share were issued to employees 
under the plan. During 1997, 26,213 shares were issued at an average price of $28.00 per share. During 1996, 32,296 shares of 
Common Stock at an average price of $19.21 per share were issued to employees under the plan. Had the Company adopted SFAS 
123, the weighted average fair value of each purchase right granted during 1998, 1997 and 1996 would have been $7.65, $9.16 and 
$5.76, respectively. The fair value was estimated at the beginning of the withholding period using the Black-Scholes option-pricing 
model with the following weighted average assumptions: (1) expected life of one half year for all years (2) expected volatility of 52%, 
51% and 41% for 1998, 1997 and 1996, respectively (3) risk-free interest rate of 4.70% for 1998, 5.43% for 1997 and 5.50% for 1996 
and 
(4) no dividend yield. 

PRO FORMA DISCLOSURES 

Had compensation cost for the Company's 1998, 1997 and 1996 grants for stock-based compensation plans been determined consistent 
with SFAS 123, the Company's net loss and net loss per share for 1998, 1997 and 1996 would approximate the pro forma amounts 
below (in thousands except per share data): 

                                                                             1998                     1997                   1996

O. SUBSEQUENT EVENTS 

ALTUS BIOLOGICS, INC. 

Altus develops, manufactures and markets products based on a novel and proprietary technology for stabilizing proteins. At December 
31, 1998, Vertex owned approximately 70% of the capital stock of Altus. On February 5, 1999, Vertex restructured its investment in 
Altus. As part of the transaction, Vertex provided Altus $3,000,000 of cash and surrendered its shares of Altus preferred stock in 
exchange for two new classes of preferred stock and warrants. The new preferred stock provides Vertex with a minority equity 
ownership position in Altus, and the warrants become exercisable upon certain events. As a result of the transaction, Altus operates 
independently from Vertex as a minority-owned subsidiary. In addition, Vertex has retained a non-exclusive royalty-free right to use 
Altus' technology for discovering, developing and manufacturing small molecule drugs.

SECOND AMENDMENT TO LEASE 

This SECOND AMENDMENT TO LEASE is made by and between David E. Clem and David M. Roby, Trustees of Fort Washington 
Realty Trust under Declaration of Trust dated June 19, 1995 and recorded with the Middlesex County (South District) Registry of 
Deeds in Book 25422, Page 360 (the "Landlord") and Vertex Pharmaceuticals Incorporated (the "Tenant"). 

Reference is hereby made to that certain lease (the "Lease") dated March 3, 1995, by and between Landlord's predecessor, Fort 
Washington Limited Partnership and Tenant with respect to a portion of the property (the "Premises") located at 40 Erie Street, 
Cambridge, Massachusetts, (the "Building") as more particularly described in the Lease as amended by a First Amendment to Lease 
(the "First Amendment"). 

WHEREAS, the Tenant has requested, and the Landlord has agreed, to further amend the Lease to add additional space to the 
Premises upon the terms and conditions set forth in this Second Amendment to Lease. 

WHEREAS, Landlord and Tenant desire to amend and modify the terms of the Lease to incorporate the additional space and to ratify 
and confirm the terms of the Lease as amended by the First Amendment as more particularly set forth below. 

NOW, THEREFORE, in consideration of the mutual promises herein contained, and other good and valuable consideration, the 
receipt and sufficiency of which are hereby acknowledged, Landlord and Tenant agree as follows: 

1. Upon occupancy by Tenant, the definition of the Premises set forth in the Lease shall be amended to include the addition of 41,132 
r.s.f. of space (the "Additional Space") in the Building currently leased to Millennium Pharmaceuticals, Inc. ("Millennium"). See 
EXHIBIT A annexed hereto for the layout of the Additional Space. 

2. Tenant shall take occupancy of the Additional Space beginning on the later of (i) the date upon which Millennium vacates the 
Additional Space, or 
(ii) March 19, 1999, and continuing for a period of ten (10) years from the date upon which Tenant occupies the Additional Space (the 
"Additional Space Term"). On or after March 19, 1999, if necessary, Landlord shall use best efforts to expedite Millennium's 
departure from the Additional Space, including filing an eviction proceeding. Landlord warrants and represents that according to the 
terms of its lease with Millennium that the lease expires on March 18, 1999 as to the Premises and the associated parking spaces. As to 
the Premises and the associated parking spaces, Landlord hereby agrees that Landlord will not extend or renew the term of 
Millennium's lease or waive any failure by Millennium to vacate. Landlord shall not be held liable for any loss or damage incurred by 
Tenant as a result of a hold-over by Millennium. Landlord represents that in addition to other sums for holding over, Millennium must 
pay a holdover premium equal to the greater of (a) twice the then fair market rent as reasonably determined by Landlord, or (b) the 
total of the Fixed Rent, Additional Rent (as those terms are defined in the Millennium lease) and all other payments then payable under 
the Millennium lease. Landlord agrees that it shall not waive the payment to Landlord of any such holdover premium by Millennium. 

2 

Provided that tenant has exercised in each instance its options to extend the Lease Term for the original Premises: (a) Tenant shall 

   2002.  EDGAR Online, Inc.

have two (2) options to extend the Additional Space Term (the "Additional Space Options") for successive periods of five (5) years 
each (the "Additional Space Extension Periods"), subject to and on the terms set forth herein. Tenant may only exercise the Additional 
Space Options with respect to the entire Additional Space. If Tenant shall desire to exercise any Additional Space Option, it shall give 
Landlord a notice (the "Additional Space Inquiry Notice") of such desire not later than fifteen (15) months prior to the expiration of 
the Additional Space Term of this Lease or the preceding Additional Space Extension Period, as the case may be. Thereafter, the Fair 
Market Rent (as defined in Subsection (c) below) for the applicable Additional Space Extension Period shall be determined in 
accordance with Subsection (d) below. After the applicable Fair Market Rent has been so determined, Tenant shall exercise each 
Additional Space Option by giving Landlord notice (the "additional Space Exercise Notice") of its election to do so not later than 
twelve (12) months prior the expiration of the Additional Space Term of this Lease, or the preceding Additional Space Extension 
Period, as the case may be. If Tenant fails to timely give either the additional Space Inquiry Notice of the Additional Space Exercise 
Notice to Landlord with respect to any Additional Space Option, Tenant shall be conclusively deemed to have waived such Additional 
Space Option hereunder. 

(b) Notwithstanding any contrary provision of this Lease, each Additional Space Option and any exercise by Tenant thereof shall be 
void and of no force or effect unless on the dates Tenant gives Landlord its Additional Space Inquiry Notice and Additional Space 
Exercise Notice for each Additional Space Option and on the date of commencement of each Additional Space Extension Period (i) 
this Lease is in full force and effect, (ii) there is no Event of Default of Tenant under this Lease, and (iii) Tenant has not assigned or 
subleased (or agreed to assign or sublease) more than fifty percent (50%) of the rentable floor area then comprising the Additional 
Space. 

(c) All of the terms, provisions, covenants, and conditions of this Lease shall continue to apply during each Additional Space 
Extension Period, except that the Additional Space Annual Fixed Rent Rate during each Additional Space Extension Period (the 
"Extension Rent") shall be equal to the fair market rent for the Additional Space determined as of the date twelve (12) months prior to 
expiration of the Additional Space Term or the preceding Additional Space Extension Period, as the case may be, in accordance with 
the procedure set forth in Subsection (d) below (the "Fair Market Rent"). 

(d) The Fair Market Rent for each Additional Space Extension Period shall be determined as follows: Within five (5) days after Tenant 
gives landlord its Additional Space Inquiry Notice with respect to any Additional Space Option, Landlord shall give Tenant notice of 
Landlord's determination of the Fair Market Rent for the applicable Additional Space Extension Period. Within ten (10) days after 
Tenant receives such notice, Tenant shall notify Landlord of its agreement with or objection to Landlord's determination of the Fair 
Market Rent, whereupon the Fair Market Rent shall be determined by arbitration conducted in the manner set forth below. If Tenant 
does not notify Landlord within such ten (10) day period of Tenant's agreement with or objection to Landlord's determination of the 
Fair Market Rent, then the Fair Market Rent of the applicable Additional Space Extension Period shall be deemed to be 

Landlord's determination of the Fair Market Rent as set forth in the notice from Landlord described in this section. 

3 

(e) If Tenant notifies Landlord of Tenant's objection to Landlord's determination of Fair Market Rent under the preceding subsection, 
such notice shall also set forth a request for arbitration and Tenant's appointment of a commercial real estate broker having at least ten 
(10) years experience in the commercial leasing market in the City of Cambridge, Massachusetts (an "Arbitrator"). Within five (5) 
days thereafter, Landlord shall by notice to Tenant appoint a second Arbitrator. Each Arbitrator shall be advised to determine the Fair 
Market Rent for the applicable Additional Space Extension Period within thirty (30) days after Landlord's appointment of the second 
Arbitrator. On or before the expiration of such thirty (30) days period, the two Arbitrators shall confer to compare their respective 
determinations of the Fair Market Rent. If the difference between the amounts so determined by the two Arbitrators is less than or 
equal to ten percent (10%) of the lower said amounts then the final determination of the Fair Market Rent shall be equal to the average 
of said amounts. If such difference between said amounts is greater than ten percent (10%), then the two arbitrators within ten (10) 
days thereafter shall appoint a third Arbitrator (the "Third Arbitrator"), who shall be instructed to determine the Fair Market Rent for 
the applicable Additional Space Extension Period within ten (10) days after his appointment by selecting one of the amounts 
determined by the other two Arbitrators. Each party shall bear the cost of the Arbitrator selected by such party. The cost of the Third 
Arbitrator, if any, shall be shared equally by Landlord and Tenant. 

3. Tenant shall accept the Additional Space in "as is" condition. Tenant acknowledges that Landlord has made, in anticipation of 
Tenant's future occupancy, for the benefit of Tenant at Landlord's sole cost and expense, certain improvements to the Additional Space 
as outlined in EXHIBIT B. Landlord agrees to consult with Tenant prior to agreeing to any changes requested by Millennium to the 
Additional Space. 

4. Upon execution of this Second Amendment to Lease, section 4.1(d) of the Lease will be stricken in its entirety and be null and void 
and of no further force and effect. 

   2002.  EDGAR Online, Inc.

5. Upon occupancy by Tenant of the Additional Space, Tenant shall pay to Landlord Annual Fixed Rent for the Additional Space in 
the amount of $1,460,186.00 (the "Additional Space Annual Fixed Rent Rate"), payable in equal monthly installments of $121,682.17 
in advance on the first day of each calendar month; and for any portion of a calendar month at the beginning or end of the Term, at that 
rate payable in advance for such portion. 

6. Article 4.1(b) shall be renumbered as 4.1(b)(1) and the following shall be added to the Lease as Article 4.1(b)(2): 

(b) (2) Adjustment for CPI - Additional Space. (a) On December 31, 2000 (the "First Adjustment Date"), the Additional Space Annual 
Fixed Rent Rate shall be increased by multiplying said rate by the lesser of (i) a fraction, the numerator of which shall be the Price 
Index (as hereinafter defined) most recently established prior to the First adjustment Date, and the denominator of which shall be the 
Base Price Index (as hereinafter defined), or (ii) one hundred four percent (104%) per year, compounded annually over the period of 
time beginning 

4 

April 1, 1997 through the First Adjustment Date. (b) On December 31, 2005 (the "Second Adjustment Date"), the Additional Space 
Annual Fixed Rent Rate (as adjusted) shall be increased by multiplying said rate by the lesser of (i) a fraction, the numerator of which 
shall be the Price Index (as hereinafter defined) most recently established prior  to the Second Adjustment Date, and the denominator of 
which shall be the Base Price Index (as hereinafter defined), or 
(ii) one hundred four percent (104%) per years, compounded annually over the five (5) years of the Additional Space Term of this 
Lease. As used herein, the term "Price Index" shall mean and refer to the "Consumer Price Index for Urban Wage Earners and Clerical 
Workers, for the Boston Massachusetts area, All Items (1982-84=100)" published by the Bureau of Labor Statistics of the United 
States Department of Labor or successor or substitute index appropriately adjusted, and the term "Base Price Index" shall mean and 
refer to the Price Index most recently established prior  to the Commencement Date. In the event of the Price Index (or a successor or 
substitute index) shall not be published for the City of Boston, Massachusetts area or for the months indicated above, the 
corresponding index for the United States City Average (and if this is not available, a reliable governmental or other nonpartisan 
publication evaluating similar or equivalent information as used in the Price Index) shall be used. In the even the Price Index ceases to 
use the 1982-84 average of 100 as the basis of calculation, or if a substantial change is made in the terms or numbers of items 
contained in the Price Index, then the Price Index shall be adjusted to the figure that would have been arrived at had the manner of 
computing the Price Index in effect at the date of this Lease not been changed. 

7. Upon commencement of the Additional Space Term, the Tenant's Proportionate Fraction as set forth in the Lease will be amended 
to 100%. 

8. The provisions of Paragraph 10.11 of the Lease shall include reference to the Additional Space Annual Fixed Rent Rate in 
determining the "Security Deposit Amount" as the same may be adjusted. Upon commencement of the Additional Space Term, the 
Tenant shall increase the Security Deposit Amount by an amount equal to one (1) year Additional Space Annual Fixed Rent plus 
additional amounts, if any, as set forth in paragraph 10.11 as amended. The Security Deposit Amount shall be adjusted as provided in 
Section 10.11 by including the Additional Space Annual Fixed Rent Rate and other rental amounts due with respect to the Additional 
Space, as the same may be adjusted in accordance with Section 4.1(b), Section 4.1(c), Section 10.12, Section 10.13 and 
Section 10.14 of the Lease as amended. The additional Security Deposit Amount may be in the form of a Letter of Credit in the form 
of Exhibit L to the Lease and must be delivered on the commencement of the Additional Space Term. 

9. Upon Tenant's reasonable request and subject to availability on the lot upon which the Building is situated, Landlord shall provide 
additional surface parking spaces to Tenant on a tenancy-at-will basis for an additional charge of $75.00 per space per month. 

10. Landlord acknowledges that Tenant presently intends to reconfigure the Additional Space upon taking occupancy. The process for 
such reconfiguration of the Additional Space shall be in accordance with paragraph 3.3 of the Lease. However, Tenant shall be under 
no obligation to reconfigure the Additional Space. 

11. Exhibit I of the Lease is hereby replaced with the Exhibit "I" attached hereto. 

5 

All capitalized terms used herein shall have the same meaning as set forth in the Lease. 

Except as otherwise expressly set forth herein, all other terms of the Lease shall apply to the Additional Space, are hereby ratified and 
confirmed and shall remain unchanged and in full force and effect.

Re: PROPOSED AGREEMENT FOR LEASE AND LEASE (THE "TRANSACTION DOCUMENTS") 

BETWEEN MILTON PARK LIMITED (THE "LANDLORD"), VERTEX PHARMACEUTICALS (EUROPE) LIMITED (THE 
"TENANT") AND VERTEX PHARMACEUTICALS INCORPORATED (THE "COMPANY") FOR UNIT 88. THE FORUM 
MILTON PARK ABINGDON OXFORDSHIRE (THE "PREMISES") 

Dear Sirs: 

The undersigned has acted as counsel to the Company in connection with its guarantee of the obligations of Vertex Pharmaceuticals 
(Europe) Limited under the Transaction Documents. 

I have reviewed the Transaction Documents, the Restated Articles of Organization of the Company and the By-Laws of the Company. 
I have also examined such other documents and records and have performed such investigation as to matters of fact and law as I have 
deemed necessary or appropriate for the purpose of this opinion. With respect to certain matters of fact, I have relied upon 
representations of the officers of the Company. 

In my examination, I have assumed the genuineness of all signatures, the authenticity of all documents submitted to me as originals, the 
conformity with the original documents of all documents submitted to me as copies or facsimiles, and the authenticity and 
completeness of the originals of such latter documents. I have assumed the due authorization and execution by the Landlord and 
Tenant of the Transaction Documents. I have assumed (without independent verification) that the Landlord has full power and 
authority to enter into, execute and deliver the Transaction Documents and perform its obligations thereunder and the conditions 
thereof in accordance with their terms. 

   2002.  EDGAR Online, Inc.

I am member of the bar of the Commonwealth of Massachusetts and I express no opinion as to any matters insofar as any laws other 
than the laws of the Commonwealth of Massachusetts may apply. This opinion is given subject further to the qualification that 
enforcement of the Transaction Documents may be affected by events or changes in the law of the Commonwealth of Massachusetts 
occurring after the date of this opinion, and I disclaim any obligation to advise you of any such events or changes in the law which 
might affect any matters or opinions set forth herein. 

Milton Park Limited 
November 2, 1998 
Page 2 

Based upon the foregoing, and subject the qualifications and exceptions herein contained, I am of the opinion that: 

1. The Company is a corporation duly organized and existing, under the laws of the Commonwealth of Massachusetts and has the 
corporate power to carry on its business as it is now being conducted and to own its property and other assets. 

2. The Company has the corporate power and legal capacity to enter into, execute and deliver the Transaction Documents and to 
perform all its obligations under the Transaction Documents. 

3. The execution and delivery of the Transaction Documents by the Company has been duly authorized by all necessary corporate 
action of the Company. 

4. Execution of the Transaction Documents by Richard H. Aldrich, Senior Vice President and Chief Business Officer of the Company, 
on behalf of the Company, will constitute and operate as due execution thereof. 

5. When the Transaction Documents are duly executed and delivered by the Company, they will be legally binding and enforceable 
against the Company in the Commonwealth of Massachusetts in accordance with their terms, subject to the qualifications in paragraph 
14 below. The performance by the Company of its obligations under the Transaction Documents will not result in the creation or 
imposition of any lien, charge, security or encumbrance upon any of its assets or properties under the law of the Commonwealth of 
Massachusetts. 

6. The execution, delivery of the Transaction Documents by the Company and performance of the Company's obligations thereunder 
will not result in any breach of or default under any provisions of Massachusetts law or under any decree of any Massachusetts 
governmental authority, agency or court or, to my actual knowledge, under any instrument or under any deed or contract to which the 
Company is a party at the date hereof or which at the date hereof binds any of the Company's property or other assets. 

7. No taxes of the Commonwealth of Massachusetts are imposed by withholding or otherwise on any payment which may become due 
from the Company under the Transaction Documents. 

8. Every consent, authorization, license or approval of, or registration with or declaration to, any governmental or public bodies or 
authorities or courts required by the Company in connection with the execution, delivery, validity, admissibility in evidence or, subject 
to the qualifications set forth in paragraph 14 below, the enforceability of the Transaction Documents or the performance by the 
Company of its obligations under the Transaction Documents including (without limitation) all payments which may become due from 
the Company in accordance with the provisions of the Transaction Documents have been obtained or made and are in full force and 
effect. 

Milton Park Limited 
November 2, 1998

9. Neither the Company, nor any of its assets, is entitled to immunity on the grounds of sovereignty or otherwise from any legal action 
or proceeding. 

10. It is not necessary to ensure the legality, validity, admissibility in evidence or, subject to the qualifications set forth in paragraph 14 
below, enforceability of the Transaction Documents that it or any other instrument be notarized, filed, recorded, registered or enrolled 
in any court, public office or elsewhere in the Commonwealth of Massachusetts or that any stamp, registration or similar tax or charge 
be paid in the Commonwealth of Massachusetts on or in relation to the Transaction Documents. 

11. The Company has the legal capacity to contract to be bound by the choice of English law in the Transaction Documents and to 

   2002.  EDGAR Online, Inc.

submit irrevocably to the jurisdiction of the English Courts under the terms of the Lease, and such a choice of law and submission to 
jurisdiction and the irrevocable agreement by the Company to accept service of process by leaving documents at the registered office 
of the Tenant will be recognized as valid under the law of the Commonwealth of Massachusetts. 

12. Any final judgment against the Company for a sum of money or order for specific performance of the Company's obligations under 
the Transaction Documents issued by a court of the Commonwealth of Massachusetts will be enforceable against the Company under 
the law of the Commonwealth of Massachusetts, subject to the qualifications set forth in paragraph 14 below. 

13. At the date of this letter, to my actual knowledge, without having made any search or investigation of the records of any court, 
governmental agency or other body, no litigation, arbitration or other legal proceedings have been commenced before and no judgment 
or award has been given or made by any court, tribunal or government agency involving the Company which would (if adversely 
determined) be likely to have a materially adverse effect on the Company's ability to observe and perform its obligations under the 
Transaction Documents or which in any way disputes or calls into question the power or authority of the Company to enter into and 
perform any such obligations. 

14. My opinions in paragraphs 5, 8, 10 and 12 with regard to the enforceability of the Transaction Documents are subject to the 
qualifications that such enforceability may be limited by (i) any applicable bankruptcy, insolvency, reorganization, fraudulent 
conveyance, moratorium or similar laws relating to or affecting the rights or remedies of creditors generally which may be in effect 
from time to time, (ii) general principles of equity (regardless of whether considered in a proceeding in equity or at law) (iii) duties and 
standards imposed on creditors and parties to contracts, from time to time, including, without limitation, requirements of good faith, 
reasonableness, fair dealing and diligence, and (iv) and by equitable principles of general application (regardless of whether such 
equitable principles are considered in an action at law or in equity), including concepts of materiality, and by possible limitations on 
certain remedial provisions contained therein. The aforesaid opinions as to enforceability of the Transaction Documents are also 
subject to the qualification that certain provisions contained in the Transaction Documents may not be enforceable, but (subject to the 
limitations set forth in the 

Milton Park Limited 
November 2, 1998 
Page 4 

foregoing clauses (i) and (ii)) such unenforceability will not render the Transaction Documents invalid as a whole or substantially 
interfere with realization of the principal benefits provided thereby. Further, I express no opinion as to the validity or enforceability of 
any provision in the Transaction Documents (i) relating to the rights of the Landlord to collect any payment which is in the nature of or 
could be construed to be a penalty, (ii) that may be deemed or construed to waive any constitutional or statutory right of the Company 
that may not lawfully be waived, (iii) relating to submission by the Borrower to the jurisdiction of English courts to the extent that a
