The accompanying notes are an integral part of these condensed consolidated financial statements. *See Note 2. 4 VERTEX PHARMACEUTICALS INCORPORATED NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS 1. BASIS OF PRESENTATION The accompanying condensed consolidated financial statements are unaudited and have been prepared by Vertex Pharmaceuticals Incorporated (the "Company") in accordance with generally accepted accounting principles. Certain information and footnote disclosures normally included in the Company's annual financial statements have been condensed or omitted. Certain prior year amounts have been reclassified to conform with current year presentation. On July 18, 2001, Vertex completed a merger with Aurora BioSciences Corporation ("Aurora"). The interim financial statements do not include the results of Aurora. The interim financial statements, in the opinion of management, reflect all adjustments (including normal recurring accruals) necessary for a fair statement of the results for the interim periods ended June 30, 2001 and 2000. The results of operations for the interim periods are not necessarily indicative of the results of operations to be expected for the fiscal year, although the Company expects to incur a substantial loss for the year ended December 31, 2001. These interim financial statements should be read in conjunction with the audited financial statements for the year ended December 31, 2000, which are contained in the Company's 2000 Annual Report to its shareholders and in its Form 10-K filed with the Securities and Exchange Commission. 2. ACCOUNTING POLICIES REVENUE RECOGNITION In the fourth quarter of 2000, retroactive to January 1, 2000, Vertex changed its method of accounting for revenue recognition in accordance with Staff Accounting Bulletin (SAB) No. 101 ("SAB 101"), Revenue Recognition in Financial Statements. Previously, the Company had recognized revenue from collaborative research and development arrangements as earned under the terms of the arrangements. License payments were recorded as revenue when the payment was assured and contractual obligations met. Payments from contractual milestones were recognized when achieved, and product research funding was recorded on a quarterly basis, when the research effort was incurred. Under the new accounting method, the Company recognizes revenue from research and development arrangements over the period of continuing involvement as prescribed by Emerging Issues Task Force No. 91-6 (EITF 91-6). Under that model, revenue is recognized for non-refundable license fees, milestones, and collaborative research and development funding using the lesser of the non-refundable cash received or the result achieved using percentage of completion accounting. Where the Company has no continuing involvement, non-refundable license fees will be recorded as revenue upon receipt and milestones will be recorded as revenue upon achievement of the milestone by the collaborative partner. Royalty revenue is recognized based upon actual and estimated net sales of licensed products in licensed territories as provided by the collaborative partner and is generally recognized in the period the sales occur. Differences between actual royalty revenues and estimated royalty revenues, which have not been historically significant, are reconciled and adjusted for in the following quarter. Product sales revenue is recognized upon shipment, when the title to product and associated risk of loss has passed to the customer. 5 VERTEX PHARMACEUTICALS INCORPORATED NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) The cumulative effect of the change in accounting principle from prior years resulted in a charge to income of $3,161,000, which is included in the loss for the six months ended June 30, 2000. Prior year financial results have been restated for the retroactive adoption of SAB 101 to January 1, 2000. DERIVATIVE INSTRUMENTS In June of 2000, the Financial Accounting Standards Board ("FASB") issued Statement of Financial Accounting Standard ("SFAS") No. 138, "Accounting for Certain Derivative Instruments and Certain Hedging Activities--an Amendment to FASB Statement No. 133." This statement establishes accounting and reporting standards for derivative instruments embedded in other contracts (collectively referred to as "derivatives") and for hedging activities. The statement requires companies to recognize all derivatives as either assets or liabilities, with the instruments measured at fair value. The accounting for changes in fair value, gains or losses, depends on the intended use of the derivative and its resulting designation. The Company has adopted this new accounting standard effective January 1, 2001 and it did not have a significant effect on the Company's financial statements. Subsequent to the issuance of SFAS No. 133, "Accounting for Certain Derivative Instruments and Hedging Activities", the FASB established the Derivatives Implementation Group ("DIG") to address and interpret practice issues relating to that standard. On March 21, 2001, the FASB approved DIG Implementation Issue No. A17 ("A17") relating to contracts that provide for net share settlement, including warrants of a privately held company. Under the proposed transition provisions for applying DIG guidance, an entity should account for the effects of initially complying with the new implementation guidance as of the first day of the fiscal quarter following posting on the FASB's website (i.e. July 1, 2001 for Vertex's implementation of A17). As of June 30, 2001 the Company held warrants meeting that definition and will adopt A17 in the third quarter of 2001. Management is currently determining the effect A17 will have on the Company's financial statements. The potential effects could result in a cumulative change in accounting principle as of July 1, 2001 and a material increase to other income in the third quarter of 2001. BASIC AND DILUTED EARNINGS (LOSS) PER COMMON SHARE Basic earnings (loss) per share is based upon the weighted average number of common shares outstanding during the period. Diluted earnings (loss) per share is based upon the weighted average number of common shares outstanding during the period plus additional 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, and the assumed conversion of convertible notes. 6 VERTEX PHARMACEUTICALS INCORPORATED NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) The following table sets forth the computation of basic and diluted earnings (loss) per common share (in thousands, except per share amounts):

7 VERTEX PHARMACEUTICALS INCORPORATED NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) 4. RESTRICTED CASH In accordance with operating lease agreements, at June 30, 2001 and 2000 the Company held in deposit approximately $25,908,000 and $9,788,000, respectively, with its bank to collateralize conditional, stand-by letters of credit in the name of the landlord. In January 2001, the Company entered into new operating leases for additional space and facilities. The letters of credit are redeemable only if the Company defaults on the leases under specific criteria. These funds are restricted from the Company's use during the lease period, $9,788,000 of funds are restricted through 2010 and the remaining $16,120,000 is restricted through 2017. The Company is entitled to all interest earned on the funds. 5. LEGAL PROCEEDINGS Chiron Corporation (Chiron) filed suit on July 30, 1998 against Vertex and Eli Lilly and Company in the United States District Court for the Northern District of California, alleging infringement by the defendants of three 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. Chiron has requested damages in an unspecified amount, as well as an order permanently enjoining the defendants from unlicensed use of the claimed Chiron inventions. During 1999, Chiron requested and was granted a reexamination by the U.S. Patent and Trademark Office of all three of the patents involved in the suit. Chiron also requested and, over the opposition of Vertex and Lilly, was granted a stay in the infringement lawsuit, pending the outcome of the patent reexamination. That reexamination proceeding is still ongoing and the stay is still in effect. While the length of the stay, the outcome of the reexamination, the effect of that outcome on the lawsuit and the final outcome of the lawsuit cannot be determined, Vertex maintains that the plaintiff's claims are without merit and intends to defend the lawsuit, if and when it resumes, vigorously. 6. RECENT ACCOUNTING PRONOUNCEMENTS In June 2001, the Financial Accounting Standards Board ("FASB") issued Statement of Financial Accounting Standard ("SFAS") No. 141, "Business Combinations" ("SFAS No. 141"). SFAS No. 141 requires that all business combinations be accounted for under the purchase method only and that certain acquired intangible assets in a business combination be recognized as assets apart from goodwill. SFAS No. 141 is effective for all business combinations initiated after June 30, 2001 and for all business combinations accounted for by the purchase method for which the date of acquisition is after June 30, 2001. In June 2001, the FASB issued SFAS No. 142, "Goodwill and Other Intangible Assets" ("SFAS No. 142"), which requires that ratable amortization of goodwill be replaced with periodic tests of the goodwill's impairment and that intangible assets other than goodwill be amortized over their useful lives. The provisions of SFAS No. 142 will be effective for fiscal years beginning after December 15, 2001, and will thus be adopted by the Company, as required, on January 1, 2002. Management is currently determining what effect, if any, SFAS No. 142 will have on its financial position and results of operations. 7. SUBSEQUENT EVENT On July 18, 2001, Vertex completed a merger with Aurora. Vertex acquired all of Aurora's outstanding common stock in a tax-free, stock for stock transaction, for approximately 14.1 million 8 VERTEX PHARMACEUTICALS INCORPORATED NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) shares of Vertex common stock. Vertex intends to account for the merger as a pooling of interests, as the business combination was initiated prior to June 30, 2001. The pro forma results are based on the historical results of Vertex and Aurora. The Company is currently evaluating the effect, if any, resulting from conforming accounting policies. The unaudited pro forma combined results for the three and six months ended June 30, 2001 and 2000, respectively, are presented below. (In thousands, except per share amounts)

9 ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS We are a global biotechnology company. We seek to discover, develop, and commercialize major pharmaceutical products independently and with partners. Chemogenomics, our proprietary, systematic, genomics-based platform, is designed to accelerate the discovery of new drugs and to expand intellectual property coverage of drug candidate compounds and classes of related compounds. This approach, which targets gene families, has formed the basis for several commercial collaborations that retain rights to downstream revenue for us. We have 12 drug candidates in development to treat viral diseases, inflammation, cancer, autoimmune diseases and neurological disorders. Our first approved product is Agenerase-Registered Trademark- (amprenavir), an HIV protease inhibitor, which we co-promote with GlaxoSmithKline. We earn a royalty from GlaxoSmithKline from sales of Agenerase. Agenerase has received approval in 33 countries worldwide, including the United States, the 15 member states of the European Union, and Japan, where the drug is sold under the trade name Prozei-TM-. We have significant collaborations with Aventis, Eli Lilly, GlaxoSmithKline ("GSK"), Kissei, Novartis, Schering AG (Germany), Serono and Taisho. These collaborations provide us with financial support and other valuable resources for our research programs, development of our clinical drug candidates, and marketing and sales of our products. We have incurred operating losses since our inception and expect to incur a loss in 2001. We believe that operating losses will continue beyond 2001 as we are planning to make significant investments in research and development for our other potential products. We expect that losses will fluctuate from year to year and that such fluctuations may be substantial. On July 18, 2001, we completed our merger with Aurora Biosciences Corporation ("Aurora"). We acquired all of Aurora's outstanding common stock in a tax-free, stock for stock transaction, for approximately 14.1 million shares of Vertex common stock. We intend to account for the merger as a pooling of interests. We are currently evaluating the effect, if any, resulting from conforming accounting policies. The merger unites Aurora's industry-leading assay development, screening and cell biology capabilities with our integrated drug discovery expertise, creating a comprehensive, scalable platform for systematically accelerating drug candidate output in target-rich gene families. The combination of Vertex's and Aurora's technology and expertise is expected to: - increase the flow of novel drug candidates into development, - accelerate the creation of a broad intellectual property estate, and - provide an enhanced opportunity for collaborations in drug discovery, development and commercialization. In the fourth quarter of 2000, we adopted SAB 101 "Revenue Recognition in Financial Statements" retroactive to January 1, 2000. SAB 101 was issued by the Securities and Exchange Commission ("SEC") in December of 1999 and provides guidance related to revenue recognition policies based on interpretations and practices followed by the SEC. The impact of our adoption of SAB 101 was to defer revenue recognition for certain portions of revenues previously recognized under our collaborative agreements into future accounting periods. During the first quarter of 2001, we recorded the full amount of the $3,161,000 expense associated with the cumulative effect of the change in accounting principle. This expense is included in the net loss and net loss per basic and diluted share for the six months ending June 30, 2000. The results of operations for the three and six months ended June 30, 2000 have been restated in accordance with SAB 101. 10 RESULTS OF OPERATIONS THREE MONTHS ENDED JUNE 30, 2001 COMPARED WITH THREE MONTHS ENDED JUNE 30, 2000. Our net loss for the three months ended June 30, 2001 was $12,107,000 or $0.20 per basic and diluted share, including merger related costs of $2,658,000, compared to net income $2,602,000 or $0.04 per diluted share for the three months ended June 30, 2000. Total revenues decreased to $21,443,000 in the second quarter of 2001 from $27,023,000 in the second quarter of 2000. In the second quarter of 2001, royalty and product sales revenue was $2,767,000 and collaborative and other research and development revenue was $18,676,000. In the second quarter of 2000, royalty and product sales revenue was $3,303,000 and collaborative and other research and development revenue was $23,720,000. Royalties and product sales include Agenerase royalty revenue from GSK. Agenerase royalty revenue is based on estimated and actual worldwide net sales of Agenerase as provided by GSK. In the second quarter of 2001 we recognized revenue from six collaborative partners. Approximately $12,431,000 of our $18,676,000 in collaborative and other research and development revenue earned during the second quarter of 2001 was earned under the Novartis collaboration. Additionally, in the second quarter of 2001 we recognized $2,381,000 in connection with our collaborations with Taisho and Serono. The balance of our collaborative and other research and development revenue for the second quarter of 2001 was earned under collaborations with Eli Lilly, Schering AG and Kissei. Comparatively, in the second quarter of 2000 we received and recognized $10,000,000 in connection with the Aventis collaboration and $7,776,000 under the Novartis collaboration. The balance of collaborative and other research and development revenue earned in the second quarter of 2000 was under the Eli Lilly, Schering AG, Kissei and Taisho collaborations. Total costs and expenses increased to $38,891,000 in the second quarter of 2001 from $27,386,000 in the second quarter of 2000. Royalties and product costs of $921,000 and $1,100,000 for the three months ended June 30, 2001 and 2000, respectively, consist of royalty payments to G.D. Searle & Co on the sales of Agenerase. The decrease in royalties and product costs is a result of decreased sales of Agenerase. Research and development expenses increased to $27,794,000 in the second quarter of 2001 from $19,824,000 in the second quarter of 2000, principally due to the continued expansion of our research and development operations and an increase in our number of drug development candidates, from eight candidates during the second quarter of 2000 to twelve candidates during the second quarter of 2001. Our expansion of our research and development operations also resulted in increases in personnel and facilities expenses, equipment depreciation and increased technology license payments for access to gene database information. We anticipate that our research and development expenses will continue to increase as we add personnel and expand our research and development activities to accommodate our existing collaborations and additional commitments we may undertake in the future. Sales, general and administrative expenses increased to $10,176,000 for the second quarter of 2001 compared to $6,462,000 for the second quarter of 2000. The increase was primarily a result of merger related costs of $2,658,000 as well as increased personnel and professional expenses. Merger related costs represent costs associated with our acquisition of Aurora which we completed on July 18, 2001. We expect sales, general and administrative expenses to continue to increase as we continue to grow. Additionally, we anticipate incurring significant merger related costs in the third quarter of 2001. Interest income increased approximately $4,978,000 to $10,441,000 in the second quarter of 2001 from $5,463,000 in the second quarter of 2000. The increase was due to a higher level of cash and investments in the second quarter of 2001 compared to the second quarter of 2000. The increase in cash and investments was primarily a result of the proceeds we received from the issuance of 11 $345,000,000 of convertible subordinated notes in September 2000. We previously issued $175,000,000 of convertible subordinated notes in March 2000, which we redeemed in September 2000. Interest expense increased to approximately $4,774,000 in the second quarter of 2001 from $2,503,000 in the second quarter of 2000. The increase was due to interest expense associated with the convertible subordinated notes we issued in September 2000. Using the equity method of accounting we recorded $326,000 as our share of loss in Altus Biologics Inc. ("Altus") for the second quarter of 2001, compared with $5,000 as our share of income for the second quarter of 2000. SIX MONTHS ENDED JUNE 30, 2001 COMPARED WITH SIX MONTHS ENDED JUNE 30, 2000 The net loss for the six months ended June 30, 2001 was $20,977,000 or $0.35 per basic and diluted share, including merger related costs of $2,658,000, compared to $16,109,000 or $0.31 per basic and diluted share, including the cumulative effect of change in accounting principle, for the six months ended June 30, 2000. Total revenues increased to $40,500,000 for the six months ended June 30, 2001 from $35,155,000 for the six months ended June 30, 2000. In the first half of 2001, revenue consisted of $5,280,000 in royalties and product sales and $35,220,000 in collaborative and other research and development revenue. In the first half of 2000, revenue consisted of $5,922,000 in royalties and product sales and $29,233,000 in collaborative and other research and development revenue. Collaborative and other research and development revenue increased $5,987,000 for the six month period ended June 30, 2001, compared with June 30, 2000 primarily due to new collaborative agreements. In May of 2000, we entered into a collaboration with Novartis to discover, develop and commercialize small molecule drugs targeted at the kinase protein family. For the six months ended June 30, 2001, we recognized $23,025,000 in connection with this collaboration, compared with $7,776,000 for the six months ended June 30, 2000. In December of 2000, we entered into a collaboration with Serono to discover, develop, and market caspase inhibitors. Previously, in November 1999, we entered into a collaborative agreement with Taisho for our caspase program. In connection with these collaborations, we recognized approximately $3,582,000 of revenue in the first six months of 2001 compared with $1,750,000 in the first six months of 2000. Included in collaborative and other research and development revenue for the six months ended June 30, 2000 is $10,000,000 earned in connection with the Aventis collaboration. Total costs and expenses increased to $73,343,000 for the six months ended June 30, 2001 from $53,439,000 for the six months ended June 30, 2000. Royalties and product costs of $1,758,000 and $1,972,000 for the first six months of 2001 and 2000, respectively, consist of royalty payments to G.D. Searle & Co on the sales of Agenerase. Research and development costs increased $15,485,000 from $38,428,000 for the six months ended June 30, 2000 to $53,913,000 for the six months ended June 30, 2001. During the first six months of 2001, we continued expansion of our research and development operations. Related to our expansion was an increase in our number of drug development candidates from eight candidates at June 30, 2000 to twelve candidates at June 30, 2001, as well as increases in personnel and facilities expenses, equipment depreciation and increased technology license payments for access to gene database information. Sales, general and administrative expenses increased $4,633,000 from $13,039,000 for the six months ended June 30, 2000 to $17,672,000 for the six months ended June 30, 2001. The increase was primarily a result of merger related costs of $2,658,000 for the first six months of 2001, as well as increased personnel and professional expenses. Merger related costs represent costs through June 30, 2001 associated with the acquisition of Aurora completed on July 18, 2001. 12 Interest income increased to approximately $21,740,000 for the first six months of 2001 from $8,706,000 for the first six months of 2000. The increase was due to a higher level of cash and investments for the six months ended June 30, 2001 compared to the same period of 2000. The increase in cash and investments was primarily a result of the proceeds we received from the issuance of $345,000,000 of convertible subordinated notes in September 2000. Interest expense increased to approximately $9,548,000 for the six months ended June 30, 2001 from $3,394,000 for the six months ended June 30, 2000. The increase was due to interest expense associated with the convertible subordinated notes we issued in September 2000. Using the equity method of accounting we recorded $326,000 as our share of loss in Altus for the six month period ended June 30, 2001, compared with $24,000 as our share of income for the six month period ended June 30, 2000. LIQUIDITY AND CAPITAL RESOURCES We have funded our operations principally through strategic collaborative agreements, public offerings and private placements of our equity and debt securities, equipment lease financing, and investment income. With the approval and launch of Agenerase in April 1999, we began receiving product royalty revenues. In 2000, we completed private placements of $175,000,000 of 5% convertible subordinated notes due March 2007 and $345,000,000 of 5% convertible subordinated notes due September 2007. We have continued to increase and advance products in our research and development pipeline. Consequently, we expect to incur losses on a quarterly and annual basis as we continue to develop existing and future compounds and to conduct clinical trials of potential drugs. We also expect to incur substantial administrative and commercialization expenditures in the future and additional expenses related to filing, prosecution, defense and enforcement of patent and other intellectual property rights. We expect to finance these substantial cash needs with future payments under our existing and future collaborative agreements, royalties from the sales of Agenerase, existing cash and investments of $675,455,000 at June 30, 2001, together with investment income earned thereon, and facilities and equipment financing. To the extent that funds from these sources are not sufficient to fund our activities, it will be necessary for us to raise additional funds through public offerings or private placements of securities or other methods of financing. There can be no assurance that such financing will be available on acceptable terms, if at all. Our aggregate cash and investments remained relatively consistent at June 30, 2001 compared with December 31, 2000, at $675,455,000 and $707,424,000, respectively. Cash used by operations, principally to fund research and development activities, was $11,271,000 during the six months ended June 30, 2001. We continue to invest in equipment and leasehold improvements for facilities to meet our operating needs associated with our growth in headcount. Cash used by investing activities for the six months ended June 30, 2001 was $152,127,000, including net purchases of available-for-sale securities, property and equipment expenditures, and an increase in restricted cash in connection with a new lease signed in January 2001. Cash provided by financing activities for the six months ended June 30, 2001 was $10,271,000, including $11,312,000 from the issuance of common stock under employee stock option and benefit plans for the six months partially offset by $1,041,000 of cash used for the repayment of capital lease obligations. 13 FORWARD-LOOKING STATEMENTS This discussion may contain forward-looking statements about the expected benefits that we will realize from our merger with Aurora, including an increased flow of novel drug candidates into development, an accelerated creation of a broad intellectual property estate and an enhanced opportunity for collaborations in drug discovery, development and commercialization. Additional forward-looking statements include our expectation that (i) our losses will continue, (ii) our research and development expenses and sales, general and administrative expenses will increase, and (iii) the Chiron litigation will not have a material adverse effect on us. While management makes its best efforts to be accurate in making forward-looking statements, such statements are subject to risks and uncertainties that could cause our actual results to vary materially. These risks and uncertainties include, among other things, our inability to successfully integrate Aurora into our existing business, costs related to the merger and the integration of Aurora, the failure to qualify the merger for pooling of interests accounting treatment, the termination of existing Aurora pharmaceutical and biotechnology collaborations, our inability to further identify, develop and achieve commercial success for new products and technologies, the possibility of delays in the research and development necessary to select drug development candidates and delays in clinical trials, the risk that clinical trials may not result in marketable products, the risk that we may be unable to successfully finance and secure regulatory approval of and market our drug candidates, our dependence upon pharmaceutical and biotechnology collaborations, the levels and timing of payments under our collaborative agreements, uncertainties about our ability to obtain new corporate collaborations and acquire new technologies on satisfactory terms, if at all, the development of competing systems, our ability to protect our proprietary technologies, patent-infringement claims, risks of new, changing and competitive technologies and regulations in the U.S. and internationally. We disclaim any intention or obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. LEGAL PROCEEDINGS Chiron Corporation (Chiron) filed suit on July 30, 1998 against Vertex and Eli Lilly and Company in the United States District Court for the Northern District of California, alleging infringement by the defendants of three 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. Chiron has requested damages in an unspecified amount, as well as an order permanently enjoining the defendants from unlicensed use of the claimed Chiron inventions. During 1999, Chiron requested and was granted a reexamination by the U.S. Patent and Trademark Office of all three of the patents involved in the suit. Chiron also requested and, over the opposition of Vertex and Lilly, was granted a stay in the infringement lawsuit, pending the outcome of the patent reexamination. That reexamination proceeding is still ongoing and the stay is still in effect. While the length of the stay, the outcome of the reexamination, the effect of that outcome on the lawsuit and the final outcome of the lawsuit cannot be determined, we believe based on the information currently available, that the ultimate outcome of the action will not have a material impact on our consolidated financial position. RECENT ACCOUNTING PRONOUNCEMENTS On March 21, 2001, the FASB approved DIG Implementation Issue No. A17 ("A17") relating to contracts that provide for net share settlement, including warrants of a privately held company. Under the proposed transition provisions for applying DIG guidance, an entity should account for the effects of initially complying with the new implementation guidance as of the first day of the fiscal quarter following posting on the FASB's website (i.e. July 1, 2001 for our implementation of A17). As of June 30, 2001, we held warrants meeting that definition and we will adopt A17 in the third quarter of 2001. We are currently determining the effect A17 will have on our financial position and results of 14 operations. The potential effects could result in a cumulative change in accounting principle as of July 1, 2001 and a material increase to other income in the third quarter of 2001. In June 2001, the Financial Accounting Standards Board ("FASB") issued Statement of Financial Accounting Standard ("SFAS") No. 141, "Business Combinations" ("SFAS No. 141"). SFAS No. 141 requires that all business combinations be accounted for under the purchase method only and that certain acquired intangible assets in a business combination be recognized as assets apart from goodwill. SFAS No. 141 is effective for all business combinations initiated after June 30, 2001 and for all business combinations accounted for by the purchase method for which the date of acquisition is after June 30, 2001. In June 2001, the FASB issued SFAS No. 142, "Goodwill and Other Intangible Assets" ("SFAS No. 142"), which requires that ratable amortization of goodwill be replaced with periodic tests of the goodwill's impairment and that intangible assets other than goodwill be amortized over their useful lives. The provisions of SFAS No. 142 will be effective for fiscal years beginning after December 15, 2001, and will thus be adopted by the Company, as required, on January 1, 2002. We are currently determining what effect, if any, SFAS No. 142 will have on our financial position and results of operations. ITEM 3.
