They do not include all information and notes required by accounting principles generally accepted in the USA for complete financial statements. It is recommended that these interim condensed consolidated financial statements be read in conjunction with the consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2002. Except as disclosed herein, there has been no material change in the information disclosed in the notes to the consolidated financial statements included in the Company's Annual Report on Form 10-K. In the opinion of management, all adjustments (consisting only of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three-month period ended March 31, 2003 are not necessarily indicative of the results that may be expected for any other interim period, or for the year ending December 31, 2003. (2) ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES (a) Organization The Company is a biopharmaceutical company focused on the discovery, development and commercialization of novel synthetic small molecule compounds for the treatment of a variety of cardiovascular, vascular and related inflammatory diseases. Since its formation in 1989, the Company has been engaged principally in research and drug discovery programs and clinical development of certain drug compounds. On July 25, 1994, the Company acquired all of the outstanding common stock of ImmunoPharmaceutics, Inc. ("IPI") in exchange for common stock, par value $.005 per share (the "Common Stock"), of the Company. On June 6, 2000, TBC, through its wholly owned subsidiary, TBC-ET, Inc., a Delaware Corporation, and ICOS Corporation, a Delaware Corporation, ("ICOS") entered into an agreement and formed ICOS-Texas Biotechnology L.P., a Delaware limited partnership ("ICOS-TBC"), to develop and globally commercialize endothelin-A receptor antagonists. TBC and ICOS were both 50% owners in ICOS-TBC until April 22, 2003, at which time the Company purchased ICOS's share of ICOS-TBC and changed the name of ICOS-TBC to Encysive, L.P. ("Encysive"). The acquisition of ICOS's ownership interest in ICOS-TBC is referred to herein as the "Acquisition". See Note 14. During the third quarter of 2000, TBC formed Revotar Biopharmaceuticals AG ("Revotar"), a German corporation, to conduct research and development for novel small molecule compounds and to develop and commercialize TBC's selectin antagonists. The Company retained an approximately 55% interest in Revotar. The Company is presently working on a number of long-term development projects that involve experimental and unproven technology, which may require many years and substantial expenditures to complete, and which may be unsuccessful. Sales of the Company's first product for which it receives royalty income, Argatroban, began during November 2000. (b) Basis of Consolidation The Company's consolidated financial statements include the accounts of the Company, its wholly owned subsidiaries, IPI and TBC-ET, Inc., and its majority controlled subsidiary, Revotar. All material intercompany balances and transactions have been eliminated. 4 (c) Cash, Cash Equivalents, Short-Term Investments and Long-Term Investments Cash equivalents are considered to be those securities or instruments with original maturities, when purchased, of three months or less. Short-term investments are those investments which have an original maturity of less than one year and greater than three months at the purchase date. Cash equivalents, short-term and long-term investments are stated at cost plus accrued interest, which approximates market value. Interest income is accrued as earned. The Company classifies all short-term and long-term investments as held to maturity. March 31, 2003 December 31, 2002 -------------- ----------------- Cash and cash equivalents: Demand and money market accounts $ 5,145 $ 609 Corporate commercial paper 21,885 20,619 -------------- -------------- Total cash and cash equivalents $ 27,030 21,228 ============== ============== Short-term investments: U.S. Government agency securities $ 5,000 $ 3,999 Corporate commercial paper and loan participations 14,569 22,333 Accrued interest on above 144 201 -------------- -------------- Total short-term investments $ 19,713 $ 26,533 ============== ============== Long-term investments: U.S. Government agency securities $ 5,000 $ 12,000 Corporate commercial paper and loan participations 8,013 7,990 Accrued interest on above 92 254 -------------- -------------- Total long-term investments $ 13,105 $ 20,244 ============== ============== (d) Equipment and Leasehold Improvements Equipment and leasehold improvements are stated at cost less accumulated depreciation and amortization. Depreciation of furniture and equipment is provided on the straight-line method over the estimated useful lives of the respective assets (3 to 10 years). Amortization of leasehold improvements is provided on the straight-line method over the remaining minimum lease term. (e) Investment in ICOS - TBC (Encysive) The Company accounts for the investment in ICOS-TBC using the equity method. Because the Company had no basis in the technology transferred to ICOS-TBC as the Company's original investment, the Company did not record an amount for its original investment. The Company records its share of the ICOS-TBC loss as a liability to related party until the Company funds its portion of the loss. ICOS-TBC paid a license fee and a milestone payment to the Company in 2000 and 2001, respectively. Because the Company has continuing obligations to ICOS-TBC, the Company deferred these amounts and is amortizing them into revenue over the estimated developmental period of the underlying technology. Approximately $1,637,000 in remaining deferred license fee and milestone income received from ICOS-TBC at the date of the Acquisition will be recognized as an offset to the purchase price paid to ICOS. Subsequent to the Acquisition, the Company's consolidated financial statements will include the accounts of ICOS-TBC. See Note 14. 5 (f) Research and Development Costs All research and development costs are expensed as incurred and include salaries of research and development employees, certain rent and related building services, research supplies and services, clinical trial expenses and other associated costs. Salaries and benefits charged to research and development in the three-month periods ended March 31, 2003 and 2002 were approximately $2,586,000 and $2,373,000, respectively. Payments related to the acquisition of in-process research and development, if any, are expensed as incurred. (g) Net Loss Per Common Share Basic net loss per common share is calculated by dividing the net loss applicable to common shares by the weighted average number of common and common equivalent shares outstanding during the period. For the three-month periods ended March 31, 2003 and 2002, the weighted average common shares used to compute basic and diluted net loss per common share totaled 43,945,274 and 43,613,146 shares, respectively. Securities convertible into Common Stock, comprised of stock options and warrants totaling 5,637,230 and 5,485,252 shares at March 31, 2003 and 2002, respectively, were not used in the calculation of diluted net loss per common share because the effect would have been antidilutive. (h) Revenue Recognition Revenue from service contracts is recognized as services are performed. Royalty revenue is recognized as products are sold by a licensee and the Company has received sufficient information to record a receivable. The Company defers the recognition of milestone payments related to contractual agreements which are still in the development stage and for which the Company continues to have obligations under the agreement. Such deferred revenues are amortized into income over the estimated remaining development period. Milestone payments received under contractual agreements which have completed the development stage are evaluated, and either recognized into income when earned, or amortized over a future period, depending upon whether or not the Company continues to have obligations under the terms of the arrangement. License fees received under the terms of licensing agreements for the Company's intellectual property are similarly deferred, and amortized into income over the estimated development period of the licensed item or items. The Company periodically evaluates its estimates of remaining development periods, and adjusts the recognition of remaining deferred revenues over the adjusted development period remaining. Revenue from grants is recognized as earned under the terms of the related grant agreements, typically as expenses are incurred. Amounts received in advance of services being performed under contracts are recorded as deferred revenue, and recognized as services are performed. (i) Patent Application Costs Costs incurred in filing for, defending and maintaining patents are expensed as incurred. (j) Use of Estimates Management of the Company has made a number of estimates and assumptions relating to the reporting of assets, liabilities, revenues and expenses and the disclosure of contingent assets and liabilities to prepare these consolidated financial statements in conformity with accounting principles generally accepted in the USA. Actual results could differ from these estimates. (k) Intangible Assets Intangible assets, included in other assets, consisting of amounts paid for products approved by the United States Food and Drug Administration ("FDA"), are amortized on a straight-line basis over their estimated useful lives. The Company periodically reviews the useful lives of its intangible 6 and long-lived assets, which may result in future adjustments to the amortization periods. Related amortization expense for each of the three-month periods ended March 31, 2003 and 2002 was $27,000. Amortization of intangible assets is included in general and administrative expense in the consolidated statements of operations and comprehensive loss. (l) Treasury Stock Treasury stock is recorded at cost. On May 3, 2001, the Company announced a stock repurchase program to buy up to 3 million shares, or approximately seven percent, of the Company's outstanding Common Stock over an 18 month period. Pursuant to the stock repurchase program, the Company had repurchased 213,000 shares for $1,602,000 during the year ended December 31, 2001. No shares were repurchased in the three-month periods ended March 31, 2003 and 2002. (m) Stock Based Compensation At March 31, 2003, the Company has six stock-based compensation plans for employees and non-employee directors, which are described more fully in Note 4. The Company accounts for those plans under the recognition and measurement principles of Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to Employees, and related interpretations. Net loss in the three- months ended March 31, 2003 and 2002 included stock-based compensation expense as a result of modifications made to certain options previously issued to retiring employees, and resulting from the grant of shares of restricted stock to certain employees. No other stock-based employee compensation expenses is reflected in net loss, however, as all options granted under those plans had an exercise price equal to the market price of the underlying Common Stock on the date of grant. The following table illustrates the effect on net loss and loss per share if the Company had applied the fair value recognition provisions of FASB Statement of Financial Accounting Standards No. 123, "Accounting for Stock-Based Compensation" to stock-based employee compensation ($ in thousands, except for per share data). Three Months Ended March 31, --------------------------------------- 2003 2002 ------------ ------------- Net loss, as reported $ (4,980) $ (6,750) Add: Stock-based employee compensation expense included in reported net loss 66 181 Deduct: Total stock-based employee compensation expense determined under fair value method for all awards (1,162) (866) ------------ ------------- Pro forma net loss $ (6,076) $ (7,435) ============ ============= Loss per share: As reported: basic and diluted $ (0.11) $ (0.15) Pro forma: basic and diluted $ (0.14) $ (0.17) 7 The per-share weighted average fair value of stock options granted during the three-month periods ended March 31, 2003 and 2002 was $0.52 and $3.53, respectively, on the grant date using the Black-Scholes option pricing model with the following assumptions: Three Months Ended March 31, ----------------------------- 2003 2002 ------------ ------------ Expected dividend yield 0.0% 0.0% Risk-free interest rate 2.5% 2.8% Expected volatility 71.9% 74.3% Expected life in years 4.24 4.53 (n) Income Taxes The Company uses the asset and liability method of accounting for income taxes. Under the asset and liability method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. (o) Impairment of Long-lived Assets As circumstances dictate, the Company evaluates the recoverability of its intangible and long-lived assets by comparing the projected undiscounted net cash flows associated with such assets against their respective carrying values. Impairment, if any, is based on the excess of the carrying value over the fair value. (p) New Accounting Pronouncements In April 2002, the FASB issued Statement of Financial Accounting Standards No. 145, "Rescission of FASB Statements No. 4, 44 and 64, Amendment of FASB Statements No. 13 and Technical Corrections," (SFAS145). SFAS145 provides guidance for income statement classification of gains and losses on extinguishments of debt and accounting for certain lease modifications that have economic effects that are similar to sale-leaseback transactions. SFAS145 was effective for the Company in January 2003. The Company's adoption of SFAS145 did not have a significant impact on its financial condition or results of operations. In July 2002, the FASB issued Statement of Financial Accounting Standards No. 146, "Accounting for Costs Associated With Exit or Disposal Activities," (SFAS146) which addresses significant issues regarding the recognition, measurement and reporting of costs that are associated with exit and disposal activities, including restructuring activities that are currently accounted for pursuant to the guidance set forth in EITF Issue No. 94-3, "Liability Recognition of Certain Employee Termination Benefits and Other Costs to Exit an Activity." SFAS146 was effective for the Company in January 2003. The Company's adoption of SFAS146 did not have a significant impact on its financial condition or results of operations. In January 2003, the FASB issued FASB Interpretation (FIN) No. 46, "Consolidation of Variable Interest Entities." FIN No. 46 requires a company to consolidate a variable interest entity if it is designated as the primary beneficiary of that entity even if the company does not have a majority of voting interests. A variable interest entity is generally defined as an entity where its equity is unable to finance its activities or where the owners of the entity lack the risk and rewards of 8 ownership. The provisions of this statement apply at inception for any entity created after January 31, 2003. For an entity created before February 1, 2003, the provisions of this Interpretation must be applied at the beginning of the first interim or annual period beginning after June 15, 2003. When the Company adopts the provisions of FIN No. 46 in the third quarter of 2003 for existing entities its investment in Encysive, L.P. will be consolidated. In April 2003, the FASB issued Statement of Financial Accounting Standards (SFAS) No. 149, "Amendment of Statement 133 on Derivative Instruments and Hedging Activities." SFAS No. 149 amends and clarifies financial accounting and reporting for derivative instruments. This statement is effective for contracts entered into or modified after June 30, 2003. The Company will adopt this statement in the third quarter of 2003 and is currently evaluating the provisions of this statement to determine its impact on the financial statements. (q) Reclassifications Certain reclassifications have been made to prior period financial statements to conform to the March 31, 2003 presentation with no effect on net loss or stockholders' equity previously reported. (3) CAPITAL STOCK The Company has reserved Common Stock for issuance as of March 31, 2003 as follows: Stock option plans....................... 7,321,346 Warrants outstanding..................... 246,586 ----------- Total shares reserved............... 7,567,932 =========== The Company's only warrants outstanding at March 31, 2003 include 142,858 warrants issued to Genentech in 1997, and 103,728 warrants granted in 1999 in connection with non-employee services. Shareholders' Rights Plan In January 2002, the Company adopted a shareholder rights plan under which the Board of Directors declared a dividend of one preferred stock purchase right ("Right") for each outstanding share of the Company's Common Stock held of record as of the close of business on January 22, 2002. Each Right initially entitles a stockholder to purchase a one one-thousandth fraction of a share of Preferred Stock - Junior Participating Series A (the "Preferred Stock") for $55.00. Each such fraction of a share of Preferred Stock has terms designed to make it essentially equivalent to one share of Common Stock. The Rights will become exercisable only in the event a person or group acquires 15% or more of the Company's Common Stock or commences a tender or exchange offer which, if consummated, would result in that person or group owning 15% of the Common Stock. Prior to such an event, the Rights will be evidenced by and traded in tandem with the Common Stock. If a person or group acquires a 15% or larger position in the Company, each Right (except those held by the acquiring party) will then entitle its holder to purchase fractional shares of Preferred Stock having twice the value of the $55.00 exercise price, with each fractional Preferred Share valued at the market price of the Common Stock. Also, if following an acquisition of 15% or more of the Company's Common Stock, the Company is acquired by that person or group in a merger or other business combination transaction, each Right would then entitle its holder to purchase Common Stock of the acquiring company having a value of twice the $55.00 exercise price. The effect will be to entitle the Company's shareholders to buy stock in the acquiring company at 50% of its market price. 9 The Company may redeem the Rights at $.001 per Right at any time on or prior to the tenth business day following the acquisition of 15% or more of its Common Stock by a person or group or commencement of a tender offer for such 15% ownership. The Rights expire on January 2, 2012. (4) STOCK OPTIONS The Company applies Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to Employees, and related interpretations in accounting for its plans and applies FASB Statement No. 123, Accounting for Stock-Based Compensation, and related interpretations in reporting for its plans.

The awarded shares will vest after completion of three years' service to the Company. The Company recorded deferred compensation expense of $309,000, which is being recognized over the vesting period. General and administrative expenses in the three-month periods ended March 31, 2003 and 2002 included $26,000 and $9,000, respectively, related to this grant. In January 2003, the Company issued 105,250 shares of restricted Common Stock to non-officer employees remaining after the restructuring. The shares will vest after completion of one year of service to the Company. The Company recorded deferred compensation expense of $162,000, which will be recognized over the vesting period. Research and Development expenses and General and Administrative expenses during the three months ended March 31, 2003 included $35,000 and $5,000, respectively related to these grants. In conjunction with the retirement of the Company's former chief executive officer, the Company modified provisions regarding vesting and time to exercise of certain stock options of the officer and recorded compensation expense of approximately $173,000, which was included in general and administrative expenses, during the three months ended March 31, 2002. 10 (5) INCOME TAXES The Company did not incur tax expense during the three-month period ended March 31, 2003, due to operating losses and the related increase in the valuation allowance. The reconciliation of income taxes at the statutory rate of 35% applied to loss before taxes for the three months ended March 31, 2003 and 2002 is as follows ($ in thousands): 2003 2002 ---- ---- Computed "expected" tax benefit $ (1,743) $ (2,362) Effect of: Permanent differences 34 178 Increase in valuation allowance 1,709 2,184 ----------- ----------- Tax benefit $ -- $ -- =========== =========== The tax effects of the temporary differences that give rise to significant portions of the deferred tax assets as of March 31, 2003 and December 31, 2002 are as follows ($ in thousands): MARCH 31, 2003 DECEMBER 31, 2002 -------------- ----------------- Loss carryforwards $ 44,475 $ 41,946 Start-up costs 7,315 8,001 Property, plant and equipment (87) (71) Deferred revenue 1,920 2,053 Other 1,062 1,047 ----------- ------------ Gross deferred tax assets 54,685 52,976 Valuation allowance (54,685) (52,976) ----------- ------------ Net deferred tax assets $ -- $ -- =========== ============ The Company has established a valuation allowance for the full amount of these deferred tax assets, as management believes that it is more likely than not that the Company will not recover these assets.

See Note 9, License Agreements, and Note 14, Subsequent Event. The Company also receives reimbursement for certain research costs pursuant to its agreements with Schering-Plough (Note 9), Revotar (Note 10) and GlaxoSmithKline ("GSK") (Note 11). (9) LICENSE AGREEMENTS Mitsubishi Pharma Agreement TBC has entered into an agreement with Mitsubishi Pharma Corporation, formerly Mitsubishi-Tokyo Pharmaceuticals, Inc. ("Mitsubishi") to license Mitsubishi's rights and technology relating to Argatroban and to license Mitsubishi's own proprietary technology developed with respect to Argatroban (the "Mitsubishi Agreement"). Under the Mitsubishi Agreement, the Company has an exclusive license to use and sell Argatroban in the U.S. and Canada for all specified indications. The Company is required to pay Mitsubishi specified royalties on net sales of Argatroban by the Company and its sublicensees after its commercial introduction in the U.S. and Canada. Either party may terminate the Mitsubishi Agreement on 60 days notice if the other party defaults in its material obligations under the agreement, declares bankruptcy or is insolvent, or if a substantial portion of its property is subject to levy. Unless terminated sooner pursuant to the above described termination provisions, the Mitsubishi Agreement expires on the later of termination of patent rights in a particular country or 20 years after first commercial sale of products. Under the Mitsubishi Agreement, TBC has access to an improved formulation patent granted in 1993 which expires in 2010, a patent on the manufacturing process to produce Argatroban that expires in 2010, and a patent for the use of Argatroban as a fibrinolysis-enhancing agent which expires in 2009. The Mitsubishi composition of matter patent on Argatroban has expired. During 2000, the Company signed an additional agreement with Mitsubishi that provides TBC with royalties on sales of Argatroban in certain European countries, and up to a total of $5.0 million in milestones for the development of ischemic stroke and certain other provisions. In conjunction with the Mitsubishi Agreement, a consulting firm involved in negotiations related to the agreement will receive a percentage of net sales received as a result of the agreement. The Company enrolled its first patient in a clinical trial for ischemic stroke in April 2001, and received a $2.0 million milestone payment in May 2001, which is being recognized in revenues over the expected development period, and accordingly, 12 revenues in the three-month periods ended March 31, 2003 and 2002 include approximately $95,000 related to such milestone payment. In light of a lack of a positive overall efficacy trend and the high risk and high costs associated with stroke trials, it is unlikely that we will proceed independently with a full Phase III program. In exchange for the license from Genentech, Inc, (the "Former Licensor") of its Argatroban technology, TBC issued the Former Licensor 285,714 shares of Common Stock during 1993 and issued an additional 214,286 shares of Common Stock on October 9, 1997, after acceptance of the filing of the first New Drug Application ("NDA") with the FDA for Argatroban. On June 30, 2000, the Company issued an additional 71,429 shares of Common Stock to Genentech in conjunction with the approval of the NDA for Argatroban in patients with heparin-induced thrombocytopenia ("HIT"). The value of $965,970 was recorded as an intangible asset and is being amortized over the estimated useful life of the asset. Amortization expense recorded in the three-month periods ended March 31, 2003 and 2002 was approximately $26,000. Additionally, on October 9, 1997, upon acceptance of the filing of the first NDA for Argatroban with the FDA, the Company granted the Former Licensor a warrant to purchase an additional 142,858 shares of Common Stock at an exercise price of $14.00 per share, subject to adjustment, which expires on October 9, 2004. TBC has also granted the Former Licensor demand and piggyback registration rights with regard to shares of Common Stock issued to the Former Licensor. ICOS Corporation Partnership On June 6, 2000, ICOS and the Company entered into the ICOS-TBC limited partnership agreement. The partnership seeks to develop and globally commercialize ET(A) receptor antagonists. As a result of the Company's contribution of technology, ICOS-TBC paid a license fee to the Company in June 2000. The license fee is being amortized over the estimated development period of the licensed technology, and the Company recognized approximately $62,000 and $121,000 of it as revenue during the three-month periods ended March 31, 2003 and 2002, respectively. Pursuant to the terms of the limited partnership agreement, ICOS-TBC was initially capitalized by a cash contribution from ICOS and the Company's contribution of intellectual property associated with sitaxsentan sodium. The intellectual property contributed by the Company to ICOS-TBC had no basis for financial reporting purposes and, accordingly, the Company assigned no value to the transfer of technology. In July 2001, the Company earned a milestone as a result of the achievement of an objective defined in the partnership agreement. The Company is recognizing the revenue associated with the milestone over the expected development period, and revenues included approximately $86,000 and $167,000 in the three-month periods ended March 31, 2003 and 2002, respectively. During the three-month periods ended March 31, 2003 and 2002, the Company recognized a loss of approximately $2,386,000 and $2,510,000, respectively, representing the Company's proportionate share of the losses of ICOS-TBC. Approximately $1,637,000 in remaining deferred license fee and milestone income received from ICOS at the date of the Acquisition will be recognized as an offset to the purchase price paid to ICOS. See Note 14. Subsequent to the Acquisition, the Company's consolidated financial statements will include the accounts of ICOS-TBC. Schering-Plough Research Collaboration and License Agreement On June 30, 2000, TBC and Schering-Plough ("Schering") entered into a worldwide research collaboration and license agreement to discover, develop and commercialize VLA-4 antagonists. VLA-4 antagonists represent a new class of compounds that has shown promise in multiple preclinical animal models of asthma. The primary focus of the collaboration will be to discover orally available VLA-4 antagonists as treatments for asthma. 13 Under the terms of the agreement, Schering obtains the exclusive worldwide rights to develop, manufacture and market all compounds from TBC's library of VLA-4 antagonists, as well as the rights to a second integrin antagonist. TBC will be responsible for optimizing a lead compound and additional follow-on compounds. Schering is supporting research at TBC and will be responsible for all costs associated with the worldwide product development program and commercialization of the compound. In addition to reimbursing research costs, Schering paid an upfront license fee and will pay development milestones and royalties on product sales resulting from the agreement. This upfront license fee is being amortized into revenue over the expected development period. License fees, milestones and grants in the three-month periods ended March 31, 2003 and 2002 included approximately $92,000, related to this upfront license fee. In June 2002, the Company achieved a milestone under the agreement with Schering as a result of the nomination of an initial candidate for Schering's further development. This milestone payment will be recognized into revenue over the expected development period. License fees, milestones and grants for the three-month period ended March 31, 2003 included approximately $45,000 related to this milestone payment. Total payments to TBC under the terms of the agreement, excluding royalties, could reach $87.0 million. Additionally, in June 2002, Schering and the Company agreed to extend Schering's support of the research collaboration to a third year, through June 30, 2003. (10) FOREIGN SUBSIDIARY During the third quarter 2000, TBC formed Revotar to conduct research and development of novel small molecule compounds and to develop and commercialize selectin antagonists. Upon formation, Revotar received certain development and commercialization rights to the Company's selectin antagonist compounds as well as rights to certain other TBC research technology. Revotar also received approximately $5 million in funding from three German venture capital funds. The Company retained ownership of approximately 55% of the outstanding common stock of Revotar and has consolidated the financial results of Revotar into TBC's consolidated financial statements. Since the development and commercialization rights contributed by the Company to Revotar had no basis for financial reporting purposes, the Company assigned no value to its contribution of intellectual property rights. The minority interest in Revotar at March 31, 2003 and December 31, 2002, was $2,418,000 and $2,608,000, respectively. The Company's consolidated net loss for the three-month periods ended March 31, 2003 and 2002 was reduced by $190,000 and $257,000, respectively, for the Revotar minority shareholders' interest in Revotar's losses. Revotar has been awarded research grants from the German government, and earned approximately $283,000 during the three-months ended March 31, 2003, which is included in license fees, milestones and grants. The Company and the other stockholders of Revotar have executed an agreement to provide approximately $4.5 million in unsecured loans, of which the Company's commitment will be approximately $3.4 million. The terms of the loans require quarterly interest payments and repayment of all principal on or before April 1, 2007. The interest rate for the first two years will be seven percent, after which the interest rate will be reset to the U.S. prime rate plus 2.5 % if such rate is higher than seven percent. Pursuant to such agreement, the Company has advanced approximately $2,237,000 to Revotar as of March 31, 2003. Revotar's management has informed the Company that they anticipate that Revotar will borrow the remaining commitment of approximately $1.1 million from the Company in the fourth quarter of 2003. The loan is denominated in U.S. dollars. To mitigate the risk of fluctuations in foreign currency exchange rates, Revotar entered into a forward contract with a bank to fix the exchange rate at which it will borrow the remaining loan commitment. As part of the agreement to form Revotar, the Company and the other initial investors agreed to issue rights to purchase common stock of Revotar held by them to Aqua Partners LLC ("Aqua"), which assisted in the formation of Revotar. The shareholders have signed an agreement that provides Aqua with the 14 option to acquire up to 3.26% of the shares owned by each shareholder for a total amount of approximately $540,000, payable to the shareholders. (11) COMMERCIALIZATION AGREEMENT In connection with TBC's development and commercialization of Argatroban, in August 1997, TBC entered into a Product Development, License and CoPromotion Agreement with GSK (the "GSK Agreement") whereby GSK was granted exclusive rights to work with TBC in the development and commercialization of Argatroban in the U.S. and Canada for specified indications. GSK paid $8.5 million in upfront license fees during August 1997, a $5 million milestone payment in October 1997, and a $7.5 million milestone payment in June 2000. Additional milestone payments may be earned upon the clinical development and FDA approval for the acute myocardial infarction indication. Future milestone payments for the acute myocardial infarction indication are subject to GSK's agreement to market Argatroban for such indication. The parties have also formed a joint development committee to analyze the development of additional Argatroban indications to be funded 60% by GSK except for certain Phase IV trials which shall be funded entirely by GSK. At this time, GSK has no plans to conduct development work for the acute myocardial infarction and stroke indications. TBC began a Phase II clinical trial in March 2001 to evaluate the use of Argatroban for ischemic stroke, and announced preliminary results in October 2002. GSK has the exclusive right to commercialize all products arising out of the collaboration, subject to the obligation to pay royalties on net sales to TBC and to the rights of TBC to co-promote these products through its own sales force in certain circumstances. TBC will retain the rights to any indications which GSK determines it does not wish to pursue (such as ischemic stroke), subject to the requirement that TBC must use its own sales force to commercialize any such indications. Any indications which TBC elects not to pursue will be returned to Mitsubishi. In conjunction with the GSK Agreement, a consulting firm involved in negotiations related to the agreement will receive a percentage of all consideration received by TBC as a result of the agreement. At present, Mitsubishi is the only manufacturer of Argatroban and has entered into the Mitsubishi Supply Agreement with GSK to supply Argatroban in bulk in order to meet GSK and TBC's needs under the GSK Agreement. Should Mitsubishi fail during any consecutive nine-month period to supply GSK at least 80% of its requirements, and such requirements cannot be satisfied by existing inventories, the Mitsubishi Supply Agreement provides for the nonexclusive transfer of the production technology to GSK. If GSK cannot commence manufacturing of Argatroban or alternate sources of supply are unavailable or uneconomic, the Company's results of operations would be materially and adversely affected. The GSK Agreement generally terminates on a country by country basis upon the earlier of the termination of TBC's rights under the Mitsubishi Agreement, the expiration of applicable patent rights or, in the case of royalty payments, the commencement of substantial third-party competition. GSK also has the right to terminate the agreement on a country by country basis by giving TBC at least three months written notice at any time before GSK first markets products in that country based on a reasonable determination by GSK that the commercial profile of the product in question would not justify continued development in that country. GSK has similar rights to terminate the GSK Agreement on a country by country basis after marketing has commenced. In addition, either party may terminate the GSK Agreement on 60 days notice if the other party defaults in its obligations under the agreement, declares bankruptcy or is insolvent. (12) 401(K) PLAN The Company has a 401(k) plan under which all employees with three months of service are eligible to participate and may contribute up to 60 % of their compensation, with a maximum contribution of $12,000 per employee in 2003. Under the terms of the Economic Growth and Tax Relief Reconciliation Act, employees aged 50 or older may contribute an additional $2,000 to the 401(k) Plan in 2003, such additional contribution would be eligible for employer matching. The Company provides a matching contribution of $0.50 on the dollar of employee contributions up to 6% of salaries. Charges to operating expense for employer match during the three-month periods ended March 31, 2003 and 2002 were approximately $46,000 and $50,000, respectively. 15 (13) COMMITMENTS AND CONTINGENCIES (a) Foreign Currency Exchange Risk The Company is exposed to market risk primarily from changes in foreign currency exchange rates. The Company has a majority-owned subsidiary in Germany and consolidates the results of operations into its consolidated financial results. Although not significant to date, the Company's reported assets, liabilities, expenses and cash flows from this subsidiary are exposed to changing exchange rates. The Company, accordingly, included an unrealized gain of $60,000 and unrealized loss of $61,000, respectively, in its comprehensive loss for the three-month periods ended March 31, 2003 and 2002. The Company had an intercompany receivable from its German subsidiary at March 31, 2003 and December 31, 2002; however, this amount is denominated in U.S. dollars and is not exposed to exchange risk. Revotar's management has informed the Company that they anticipate that Revotar will borrow the remaining commitment of approximately $1.1 million from the Company in the fourth quarter of 2003. The loan is denominated in U.S. dollars. To mitigate the risk of fluctuations in foreign currency exchange rates, Revotar entered into a forward contract with a bank to fix the exchange rate at which it will borrow the remaining loan commitment. The Company contracts with entities in other areas outside the U.S. and these transactions are denominated in a foreign currency. To date, the currencies of these other countries have not fluctuated materially. (b) Other Contingencies Like other biopharmaceutical companies, the Company is subject to other contingencies, including legal proceedings and claims arising out of its business that cover a wide range of matters, including, among others, environmental matters, contract and employment claims, and product liability. The Company may be involved in legal actions from time to time. The Company has used various substances in its research and development which have been or may be deemed to be hazardous or dangerous, and the extent of its potential liability, if any, under environmental, product liability and workers' compensation statutes, rules, regulations and case law is unclear. The Company is presently involved in several legal actions, none of which are expected to have a material adverse effect upon the results of operations or financial condition of the Company when considered either individually or in the aggregate. (14) SUBSEQUENT EVENT On April 22, 2003, the Company and ICOS executed a purchase and sale agreement (the "Agreement") pursuant to which the Company purchased the partnership interest of ICOS and its subsidiaries in ICOS-TBC. Under the Agreement, the Company agreed to pay to ICOS a purchase price of $10,000,000, of which $4,000,000 was paid on April 22, 2003. The remaining $6,000,000 is subject to a secured promissory note (the "Note") which requires a payment of $4,000,000 on April 22, 2004, and a payment of $2,000,000 on October 22, 2004. The outstanding principal balance of the Note shall accrue interest at a rate which approximates the three-month London interbank offering rate for U.S. Dollars (LIBOR) plus 1.5%. The interest rate was established on April 22, 2003 at approximately 2.82% and will be adjusted on the first business day of each April, July, October and January thereafter (the LIBOR Adjustment Dates). Interest is payable on or before the tenth day after each LIBOR Adjustment Date. The Company's obligations under the Note are secured with an irrevocable standby letter of credit, for which the Company has pledged marketable securities with a value of approximately $7,000,000. Approximately $1,637,000 in remaining deferred license fee and milestone income received from ICOS at the date of the Acquisition will be recorded as a reduction in the acquisition cost recorded by the Company, resulting in a charge to operating expenses of approximately $8,363,000 in the second quarter of 2003. Following the Acquisition, the Company has changed the name of ICOS-TBC to Encysive, L.P. The Company's consolidated financial statements will include the accounts of Encysive, L.P.. 16 ITEM 2. TEXAS BIOTECHNOLOGY CORPORATION AND SUBSIDIARIES MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS THREE MONTHS ENDED MARCH 31, 2003 AND MARCH 31, 2002 OVERVIEW The following discussion of our financial condition and results of operations should be read in conjunction with our consolidated financial statements and the related notes to the financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2002, and our condensed consolidated financial statements and the related notes to the financial statements included in this Quarterly Report on Form 10-Q. Since our inception in 1989, we have primarily devoted our resources to funding drug discovery, research and development. We are a biopharmaceutical company focused on the discovery, development and commercialization of novel, synthetic, small molecule compounds for the treatment of a variety of cardiovascular, vascular and related inflammatory diseases. We believe that synthetic, small molecule therapeutics have several advantages over protein and peptide based large molecules. Small molecules generally are not immunogenic, can typically be protected with composition-of-matter patents and can be produced by conventional lower cost pharmaceutical manufacturing methods. Our research and development programs are focused on inhibitors (also referred to as antagonists or blockers) that can interrupt certain disease processes. Our programs seek to address unmet medical needs in cardiovascular diseases, thrombocytopenia, pulmonary arterial hypertension, heart failure and inflammatory diseases such as asthma. In the biopharmaceutical industry, a substantial percentage of the profits generated from successful drug development are typically retained by the entity directly involved in the sales and marketing of the drug. Licensing our drug candidates to a third party who will complete development and provide sales and marketing resources in exchange for upfront payments, milestone payments and a royalty on sales may reduce some of our risks, particularly for diseases outside our strategic interest or in territories outside of the United States and Canada. In June 2000, we established ICOS-TBC, a 50/50-owned limited partnership with ICOS Corporation ("ICOS"), to develop and commercialize endothelin receptor antagonists, including sitaxsentan and TBC3711. In January 2003, ICOS announced that they had reached a conclusion that joint development of the endothelin receptor antagonist program should not continue, and in April 2003, we purchased the partnership interest of ICOS in ICOS-TBC for a purchase price of $10 million. Following the Acquisition, as discussed below, we intend to continue the development of the endothelin receptor antagonist program. Our strategy for managing our capital requirements includes seeking to license rights to sitaxsentan for select markets, while preferably retaining North American rights. APPROVED DRUGS IN COMMERCIAL MARKET ARGATROBAN Argatroban was approved by the FDA in 2000, is indicated for prophylaxis or treatment of thrombosis in patients with heparin-induced thrombocytopenia ("HIT") and for use in HIT patients undergoing percutaneous coronary intervention ("PCI".) Argatroban was approved in Canada in 2002 for use as anticoagulant therapy in patients with heparin-induced thrombocytopenia syndrome. During 2002, we completed initial studies to evaluate the use of Argatroban in hemodialysis patients and in PCI. The drug is being marketed in the U.S. and Canada by GlaxoSmithKline, plc ("GSK") and has been on the 17 market in the U.S. and Canada since November 2000 and June 2002, respectively. GSK is our development, manufacturing and marketing partner for Argatroban. GSK currently markets Argatroban and enjoys market exclusivity pursuant to the Waxman/Hatch Act that provides protection from competition until June 30, 2005. We recently received a formal Written Request from FDA to conduct a study with Argatroban in pediatric patients. Upon completion of this study, we will be eligible for an additional 6 months of market exclusivity. Argatroban is currently marketed in a formulation that is covered under a formulation patent that expires in 2010. We will also be submitting a process patent, that would expire in 2019, to the FDA for inclusion in the FDA Orange Book of Approved Drug Products. Following expiration of Waxman/Hatch protection, it is possible that generic manufacturers may be able to produce Argatroban without violating the formulation or process patents. The composition of matter patent on Argatroban has expired. The Company has access to other patents held by Mitsubishi, however, these are not being utilized currently. RESEARCH AND DEVELOPMENT PROGRAMS Presently, we have four major product development programs. Endothelin Antagonist Program. We are developing sitaxsentan, an endothelin(A) receptor antagonist, or ET(A), for the treatment of pulmonary arterial hypertension. During June 2000, we formed a partnership, ICOS-TBC, with ICOS Corporation to develop and commercialize ET(A) receptor antagonists. During 2002, ICOS-TBC successfully completed a Phase IIb/III pivotal clinical trial in pulmonary arterial hypertension with sitaxsentan. TBC3711, a second generation ET(A), has previously completed Phase I clinical trials and may be developed for cardiovascular or other diseases. Following the Acquisition, discussed above, we intend to initiate a final pivotal study in PAH during the second quarter of 2003, to include 50 and 100 mg oral doses of sitaxsentan, placebo and bosentan. Thrombosis. During 2002, we completed a Phase II human clinical trial for Argatroban as a mono-therapy treatment for acute ischemic stroke. The clinical trial met the primary endpoint based on safety and showed positive results in the secondary safety endpoint. In light of a lack of a positive overall efficacy trend and the high risk and high costs associated with stroke trials, it is unlikely that we will proceed independently with a full Phase II program. Currently, Argatroban is being evaluated in a clinical trial in combination with recombinant tissue Plasminogen Activator (rt-PA) as a new approach to the treatment of acute ischemic stroke by an investigator at the University of Texas Medical School at Houston. Vascular Inflammation Program. Revotar, our majority owned German affiliate located in Berlin is developing a selectin antagonist, bimosiamose, for the treatment of asthma and psoriasis. The intravenous form of the drug demonstrated positive anti-inflammatory effects in Phase II clinical trials. Revotar was formed during 2000, to further the development of this program. Revotar completed Phase I clinical trials for asthma utilizing an inhaled form of bimosiamose. A Phase IIa clinical trial is currently being conducted with an inhaled form of bimosiamose and a Phase IIa clinical trial in psoriasis is planned to commence during the first half of 2003, using a topical formulation. A Phase IIa proof-of-concept clinical trial in psoriasis, completed during 2002 with an injectable form of bimosiamose, demonstrated efficacy. We are also conducting research with respect to other cell adhesion molecules including vascular cell adhesion molecule, or VCAM, junctional adhesion molecules, or JAM 2/3 and several integrins including very late antigen 4, or VLA-4, (alpha)4(beta)7 and others to develop antagonists for the treatment of asthma, rheumatoid arthritis, multiple sclerosis, restenosis and inflammatory bowel disease. We have signed a collaboration and license agreement for the VLA-4 program with Schering-Plough and have received a milestone payment from Schering-Plough for nominating a compound as a clinical candidate. Additionally, we are conducting research on backup VLA-4 antagonists for Schering-Plough under this agreement. Vascular Disease. Many disease processes involve changes in blood vessels and heart tissue. There are numerous mediators, like endothelin, which may contribute to the development of these diseases. Several of these act though G-protein coupled receptors, GPCRs, to carry out their action. We are conducting research on urotensin and other GPCRs to identify inhibitors which could be useful in treating diseases including congestive heart failure, CHF, ischemic stroke and acute myocardial infarction. 18 RESULTS OF OPERATIONS CRITICAL ACCOUNTING POLICIES Revenue Recognition o We recognize revenue from service contracts as services are performed. o Royalty revenue is recognized as products are sold by a licensee and we have received sufficient information to record a receivable. Our royalty revenue is based on net sales of product, that is, sales net of discounts, returns and allowances. We have estimated a percentage of gross sales, based on recent experience, as an allowance for future returns, however there can be no assurance that our estimate will be accurate. o Revenue from collaborative research and development activities is recognized as services are performed. o We defer the recognition of milestone payments related to contractual agreements which are still in the development stage. Such deferred revenues are amortized into income over the estimated remaining development period. Milestone payments received under contractual agreements which have completed the development stage are evaluated, and either recognized into income when earned, or amortized over a future period, depending upon whether or not the Company continues to have obligations under the terms of the arrangement. o License fees received under the terms of licensing agreements for our intellectual property are similarly deferred, and amortized into income over the estimated developmental period of the licensed item or items. o Revenue from grants is recognized as earned under the terms of the related grant agreements, typically as expenses are incurred. Amounts received in advance of services being performed under contracts are recorded as deferred revenue, and recognized as services are performed. We periodically evaluate our estimates of remaining development periods, and adjust the recognition of remaining deferred revenues over the adjusted development period remaining. Partnership Accounting From its inception in June 2000 through December 31, 2002, we and ICOS shared equally in the costs of ICOS-TBC. In January 2003, however, ICOS informed us that they had reached the conclusion that joint development of the endothelin receptor antagonist program through ICOS-TBC should not continue. As a result, since January 2003 we have agreed to be responsible for 100% of the costs of ICOS-TBC. Following the Acquisition, we have increased our ownership and potential commercial benefit of the endothelin receptor antagonist program from 50% to 100%. Operating results of ICOS-TBC include expenses related to our internal research staff that we recognize as revenue and record as collaborative research and development revenue from ICOS-TBC. Due to the nature of the ICOS-TBC collaborative agreement, our collaborative research and development revenue from ICOS-TBC largely depends on the continued progression of clinical trial and development activities, and can be expected to vary from quarter to quarter and year to year. From its inception in June 2000 through March 31, 2003, we have accounted for our investment in ICOS-TBC under the equity method. As a result of the Acquisition, in the future we will include the accounts of Encysive, L.P. in our consolidated financial statements. A result of the consolidation of Encysive, L.P. with our financial statements is that the revenue item, "Collaborative research and development from ICOS-TBC, L.P." and the expense item, "Equity in loss of ICOS-TBC, L.P." will be eliminated. The operating expenses of Encysive will be included in our operating expenses. 19 Remaining deferred revenue, comprised of the portion of the license fee and milestone payment received from ICOS that has not been recognized as revenue totaled $1,637,000 at March 31, 2003. The recognition of this amount upon the Acquisition will offset the effect of the $10,000,000 purchase price paid to ICOS and result in a net charge of approximately $8,363,000 in the second quarter of 2003. Stock Options We apply Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees", and related interpretations ("APB 25") in accounting for our stock option plans and apply FASB Statement No. 123, "Accounting for Stock-Based Compensation", and related interpretations ("FAS 123") in reporting for our stock option plans. APB 25 utilizes the "intrinsic value" of stock options, defined as the difference between the exercise price of an option and the market price of the underlying share of common stock, on the "measurement date" which is generally the date of grant. Since the exercise price of employee stock options issued under our plans is set to match the market price of our Common Stock, there is generally no compensation expense recognized upon grant of employee stock options. Options granted to non-employees, if any, are valued at the "fair value" of the option as defined by FAS 123, utilizing the Black-Scholes option pricing model. We recorded compensation expense for the "fair value" of options granted to non-employees. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. GENERAL Our operating results have fluctuated significantly during each quarter, and we anticipate that such fluctuations, which are largely attributable to varying research and development commitments and expenditures, will continue for the next several years. We have been unprofitable to date and expect to incur substantial operating losses for the next several years as we invest in product research and development, preclinical and clinical testing and regulatory compliance. We may initiate certain commercial activities in the future, which could contribute to future operating losses. We have sustained net losses of approximately $153.1 million from the date of our inception to March 31, 2003. We have primarily financed our operations to date through a series of private placement and public offerings of our Common Stock and several collaborative agreements with third parties to jointly pursue product research and development. See discussion of "Liquidity and Capital Resources" below. See also "Additional Risk Factors" in Item 1 "Business" of our Annual Report on Form 10-K for the year ended December 31, 2002. THREE MONTH PERIODS ENDED MARCH 31, 2003 AND 2002 Revenues increased $623,000, or approximately 24.0% in the three months ended March 31, 2003, compared with the three months ended March 31, 2002. The increase was comprised of increased collaborative research and development revenues from ICOS-TBC, increased royalty income and increased license fees, milestones and grants. Research agreement revenues, however, declined $177,000 or approximately 19%. During the prior year quarter, we, along with GSK, were conducting clinical trials for additional uses of Argatroban and those trials completed during 2002. Collaborative research and development from ICOS-TBC, L.P. in the quarter ended March 31, 2003 increased $424,000, or approximately 177% compared with the quarter ended March 31, 2002. Beginning January 1, 2003, a significantly higher percentage of the development activity was performed by our employees than in previous periods. 20 Royalty income from the sales of Argatroban increased $183,000, or approximately 19% as a result of increased sales by GSK. During 2002, GSK created a hospital based sales force and initiated programs to increase its sales efforts on Argatroban in the U.S. and Canada that we believe could have a positive effect on our royalties from GSK. License fees, milestones and grants increased $187,000, or approximately 39%, primarily due to the receipt of German government grants by Revotar during the quarter ended March 31, 2003. Research and development expense decreased $971,000, or approximately 19% in the three months ended March 31, 2003, compared with the three months ended March 31, 2002. The decrease is primarily due to a reduction in clinical trials expenses of $1,092,000 as we were conducting several trials, primarily ARGIS-I for Argatroban in stroke, during the prior year quarter. During the quarter ended March 31, 2003, research and development expense includes a restructuring charge, primarily comprised of severance benefits paid to terminated employees, of $503,000. In January 2003, we announced a reduction of headcount, primarily in the areas of basic exploratory biology, early stage target identification and support functions. As a result of the headcount reduction, our ongoing employee costs for research and development declined $392,000 in the three months ended March 31, 2003, compared with the three months ended March 31, 2002. Equity in loss of ICOS-TBC, L.P. declined $124,000, or approximately 5%, in the three months ended March 31, 2003, compared with the three months ended March 31, 2002. Our equity in loss for the three months ended March 31, 2002 is comprised of 50% of the loss of ICOS-TBC, which totaled $5,020,000. Our equity in loss for the three months ended March 31, 2003 is comprised of 100% of the loss of ICOS-TBC. The expenses of ICOS-TBC declined in the current year primarily in clinical trial costs, as the STRIDE trial was in progress during the prior year period. General and administrative expenses declined $513,000, or approximately 19% in the three months ended March 31, 2003, compared with the three months ended March 31, 2002. The prior year period included stock compensation expenses of $182,000, primarily resulting from modifications to stock options issued to our retiring CEO. General and administrative expenses in 2003 include $53,000 in costs related to the January 2003 restructuring. The remaining decrease in general and administrative expenses is primarily due to reduced travel and other employee related costs. In 2003 we intend to continue with strict cost control measures to minimize cash spent on administrative activities. Total operating expenses declined $1,608,000, or approximately 16% in the three months ended March 31, 2003, compared with the three months ended March 31, 2002. Operating expenses in the three months ended March 31, 2003 include a charge of $556,000 resulting from the restructuring of our research activities in January 2003. Operating expenses in the three months ended March 31, 2002 include stock compensation expenses of $182,000, primarily resulting from modifications to stock options issued to our retiring CEO. After taking these charges into consideration, other operating expenses declined $1,958,000, or approximately 19% in the current quarter, compared to the comparable prior year quarter. As discussed above, the decline is primarily due to reduced clinical trials costs and reduced headcount during the current year quarter. Operating loss declined $2,231,000, or approximately 29%, in the three months ended March 31, 2003, compared with the three months ended March 31, 2002, due to higher revenues and reduced operating expenses in the current year period. Investment income declined $394,000, or approximately 51% in the three months ended March 31, 2003, compared with the three months ended March 31, 2002 due to lower levels of funds available for investment in the current quarter. The minority interest in the loss of Revotar in the three months ended March 31, 2003 declined $67,000, or approximately 26% compared to the three months ended March 31, 2002, reflecting reduced expenses, primarily clinical trials costs, at Revotar in the current year quarter. 21 Net loss in the three months ended March 31, 2003 declined $1,770,000, or approximately 26% compared with the three months ended March 31, 2002. The decreased net loss in the current quarter is due to higher revenues and lower operating expenses in the current quarter, partially offset by reduced investment income in the current quarter, all as discussed above. LIQUIDITY AND CAPITAL RESOURCES We have financed our research and development activities and other operations primarily through public and private offerings of our Common Stock and from funds received through our collaborations, research agreements and partnerships. We also have received royalty revenue from sales of Argatroban. We have not conducted any offerings in 2003, and have relied on our cash balances from prior offerings and our revenues to fund operations, with the result that our cash balance has decreased in 2003. Cash, cash equivalents and investments in marketable securities, including accrued interest thereon, was $59,848,000 at March 31, 2003, compared with $68,005,000 at December 31, 2002. We used $7,876,000 in cash in operating activities during the three months ended March 31, 2003, compared to cash used in operating activities of $7,526,000 during the three months ended March 31, 2002. The increased use of cash in the current year period is primarily due to the effect of changing our relationship with ICOS in January 2003, after which we became responsible for 100% of the costs of Encysive, L.P. As a result of the Acquisition, as discussed in Note 14 to the Financial Statements included herein, we have made a payment to ICOS of $4 million on April 22, 2003 and agreed to pay $4 million in April 2004 and $2 million in October 2004. The Note is secured with an irrevocable standby letter of credit for which we have pledged marketable securities with a value of approximately $7,000,000. Pledged securities will be returned to us by the bank as payments are made on the Note. Investing activities generated $13,685,000 during the three months ended March 31, 2003, compared to $23,636,000 in the three months ended March 31, 2002. Purchases of equipment and leasehold improvements declined $1,189,000 in the current quarter, as a result of programs implemented by management to conserve cash. Other than expenditures for purchases of equipment and leasehold improvements, investing activities consist of purchases of, and maturities of investments. During the quarter ended March 31, 2002, the net cash provided from investing activities was primarily used to fund an increase of cash and cash equivalents in that quarter of $16,222,000. In the current quarter, cash and cash equivalents increased $5,802,000, which was primarily funded from investing activities. Cash flows from financing activities in the quarter ended March 31, 2002 of $157,000 reflected proceeds from the sale of Common Stock and option exercises. There was no financing activity in the quarter ended March 31, 2003. Material Commitments As a result of the Acquisition, as discussed in Note 14 to the Financial Statements included herein, we have made a payment to ICOS of $4 million on April 22, 2003 and agreed to pay $4 million in April 2004 and $2 million in October 2004. The Note is secured with an irrevocable standby letter of credit for which we have pledged marketable securities with a value of approximately $7,000,000. Pledged securities will be returned to us by the bank as payments are made on the Note. Our only other material contractual commitments are comprised of a loan commitment to Revotar and office and laboratory facility leases. We and the minority shareholders of Revotar have committed to lend Revotar, on an unsecured basis, approximately $4.5 million, of which our commitment is approximately $3.4 million. The terms of the loans require quarterly interest payments and repayment of all principal on or before April 1, 2007. Our portion of the loan is denominated in U.S. dollars at an interest rate of seven percent fixed for the first two years and resets to the greater of seven percent or U.S. prime plus two and one-half percent on April 1, 2004. As of March 31, 2003, we have advanced $2,237,000 to Revotar under our loan commitment. Revotar will need to seek additional funding through collaborative arrangements and/or through public or private financings in the future. If they are not 22 successful, Revotar will be unable to repay our loans. A likely result of additional financings would be to reduce our ownership percentage in Revotar. The Company had long-term obligations under our office and laboratory leases as follows (in thousands): Less than 1-3 4-5 After 5 Contractual Obligations Total 1 year years years years ----------------------- ------ ------ ----- ----- ----- Operating Leases $ 4,873 $ 1,616 $ 3,126 $ 131 -- Outlook for 2003 In connection with the Acquisition, we have announced new guidance for 2003 as follows: Net sales of Argatroban by GSK..................$30.0 to $35.0 million Revenues........................................$10.0 to $11.5 million Expenses (1)....................................$50.0 to $53.0 million Investment income...............................$0.8 to $1.0 million Estimated net loss..............................$39.0 to $42.0 million Cash and Investments at Year-End 2003...........$30.0 to $32 million (1).Expenses net of minority interest in Revotar and include a charge of $8.4 million related to the Acquisition. For a number of reasons discussed elsewhere in this Form 10-Q, we cannot estimate, with a reasonable degree of certainty, total completion costs or dates of completion of our ongoing research and development projects. See "Additional Risk Factors" in Item 1, "Business" of our annual report on Form 10-K for the year ended December 31, 2002, and "Longer-Term Outlook", below. Longer-Term Outlook We expect to continue to incur substantial research and development expenditures as we design and develop biopharmaceutical products for the prevention and treatment of cardiovascular and other diseases. We anticipate that our operating expenses will increase in subsequent years because: o We expect to incur significant expenses in conjunction with additional clinical trial costs for sitaxsentan and research and clinical trial costs for development of bimosiamose compounds and expect to begin to incur cost for clinical trials related to additional compounds. These costs include: - hiring personnel to direct and carry out all operations related to clinical trials; - hospital and procedural costs; - services of contract research organizations; and - purchasing and formulating large quantities of the compound to be used in such trials. o There will be additional costs in future periods related to Argatroban in complying with ongoing FDA requirements and possible clinical trial expenditures for additional therapeutic indications. We have been unprofitable to date and expect to incur operating losses for the next several years as we invest in product research and development, preclinical and clinical testing and regulatory compliance. We will require substantial additional funding to complete the research and development of our product candidates, to establish commercial scale manufacturing facilities, if necessary, to fund the $6 million 23 required future payments to ICOS and to market our products. Estimates of our future capital requirements will depend on many factors, including: o market acceptance and commercial success of Argatroban; o expenses and risks associated with clinical trials to expand the use of Argatroban; o possible emergence of generic competition; o continued scientific progress in our drug discovery programs; o the magnitude of these programs; o progress with preclinical testing and clinical trials; o the time and costs involved in obtaining regulatory approvals; o the costs involved in filing, prosecuting and enforcing patent claims; o competing technological and market developments and changes in our existing research relationships; o our ability to maintain and establish additional collaborative arrangements; and o effective commercialization activities and arrangements. Subject to these factors, we anticipate that our existing capital resources and other revenue sources, should be sufficient to fund our cash requirements through the end of the third quarter of 2004. We anticipate that we may need to secure additional funds to continue the required levels of research and development to reach our current long-term goals. We intend to seek such additional funding through collaborative arrangements and/or through public or private financings, if required. Our strategy for managing our capital requirements includes seeking to license rights to sitaxsentan for select markets, while preferably retaining North American rights. There can be no assurances that such funding or licensing arrangements will be available on acceptable terms. As we review our research and development programs, we may also consider various measures to reduce our costs in order to effectively utilize our capital resources. Off-Balance Sheet Arrangements We do not engage in off-balance sheet financing arrangements. HAZARDOUS MATERIALS AND ENVIRONMENTAL MATTERS Our research and development processes involve the controlled use of hazardous materials, chemicals and radioactive materials and produce waste products. We are subject to federal, state and local laws and regulations governing the use, manufacture, storage, handling and disposal of hazardous materials and waste products. Although we believe that our safety procedures for handling and disposing of hazardous materials comply with the standards prescribed by laws and regulations, the risk of accidental contamination or injury from these materials cannot be eliminated completely. In the event of an accident, we could be held liable for any damages that result. This liability could exceed our resources or not be covered by our insurance. Although we believe that we are in compliance in all material respects with applicable environmental laws and regulations, there can be no assurance that we will not be required to incur significant costs to comply with environmental laws and regulations in the future. There can also be no assurance that our operations, business or assets will not be materially adversely affected by current or future environmental laws or regulations. 24 IMPACT OF INFLATION AND CHANGING PRICES The pharmaceutical research industry is labor intensive, and wages and related expenses increase in inflationary periods. The lease of space and related building services for the Houston facility contains a clause that escalates rent and related services each year based on the increase in building operating costs and the increase in the Houston Consumer Price Index, respectively. To date, inflation has not had a significant impact on our operations. CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS This Form 10-Q contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). All statements other than statements of historical fact included in and incorporated by reference into this Form 10-Q are forward-looking statements. These forward-looking statements include, without limitation, statements regarding our estimate of the sufficiency of our existing capital resources and our ability to raise additional capital to fund cash requirements for future operations, and regarding the uncertainties involved in the drug development process and the timing of regulatory approvals required to market these drugs. Although we believe that the expectations reflected in these forward-looking statements are reasonable, we cannot give any assurance that such expectations reflected in these forward-looking statements will prove to have been correct. The ability to achieve our expectations is contingent upon a number of factors, which include, without limitation: o market acceptance and commercial success of Argatroban; o expenses and risks associated with clinical trials to expand the use of Argatroban; o effect of any current or future competitive products; o the possible emergence of generic competition; o continued scientific progress in our drug discovery programs; o the magnitude of these programs; o progress with preclinical testing and clinical trials; o the time and costs involved in obtaining regulatory approvals; o the costs involved in filing, prosecuting and enforcing patent claims; o competing technological and market developments and changes in our existing research relationships; o our ability to maintain and establish additional collaborative arrangements; o retention of key personnel; o capital market conditions; and o effective commercialization activities and arrangements. When used in this Form 10-Q, the words "expect," "anticipate," "intend," "plan," "believe," "seek," "estimate" and similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words. Because these forward-looking statements 25 involve risks and uncertainties, actual results could differ materially from those expressed or implied by these forward-looking statements for a number of important reasons, including those discussed under "Management's Discussion and Analysis of Financial Condition and Results of Operations - Liquidity and Capital Resources." You should read these statements carefully because they discuss our expectations about our future performance, contain projections of our future operating results or our future financial condition, or state other "forward-looking" information. Before you invest in our Common Stock, you should be aware that the occurrence of any of the contingent factors described herein under "Management's Discussion and Analysis of Financial Condition and Results of Operations - Liquidity and Capital Resources" and described under "Additional Risk Factors" in our Annual Report on Form 10-K for the year ended December 31, 2002 could substantially harm our business, results of operations and financial condition. Upon the occurrence of any of these events, the trading price of our Common Stock could decline, and you could lose all or part of your investment. We cannot guarantee any future results, levels of activity, performance or achievements. Except as required by law, we undertake no obligation to update any of the forward-looking statements in this Form 10-Q after the date of this Form 10-Q. ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK FOREIGN CURRENCY EXCHANGE RISK We are exposed to market risk primarily from changes in foreign currency exchange rates. The following describes the nature of this risk that is not believed to be material to us. We have a majority-owned subsidiary in Germany and consolidate the results of operations into our consolidated financial results. Although not significant to date, our reported assets, liabilities, expenses and cash flows from this subsidiary are exposed to changing exchange rates. We, accordingly, included an unrealized gain of $61,000 and an unrealized loss of $61,000, respectively, in our comprehensive loss for the three-month periods ended March 31, 2003 and 2002. We had an intercompany receivable from its German subsidiary at March 31, 2003 and December 31, 2002; however, this amount is denominated in U.S. dollars and is not exposed to exchange risk. The Company contracts with entities in other areas outside the U.S. and these transactions are denominated in a foreign currency. To date, the currencies of these other countries have not fluctuated materially. At this time, management has not deemed it cost effective to engage in a program of hedging the effect of foreign currency fluctuations on the Company's operating results using derivative financial instruments. The Company and the other stockholders of Revotar have executed an agreement to provide approximately $4.5 million in unsecured loans, of which the Company's commitment will be approximately $3.4 million. The terms of the loans require quarterly interest payments and repayment of all principal on or before April 1, 2007. The interest rate for the first two years will be seven percent, after which the interest rate could then be reset to the U.S. prime rate plus 2.5 % if such rate is higher than seven percent. Pursuant to such agreement, the Company has advanced approximately $2,237,000 to Revotar as of March 31, 2003. Revotar's management has informed the Company that they anticipate that Revotar will borrow the remaining commitment of approximately $1.1 million from the Company in the fourth quarter of 2003. The loan is denominated in U.S. dollars. To mitigate the risk of fluctuations in foreign currency exchange rates, Revotar entered into a forward contract with a bank to fix the exchange rate at which it will borrow the remaining loan commitment ITEM 4. CONTROLS AND PROCEDURES Within 90 days prior to the filing date of this report, we carried out an evaluation, under the supervision and with the participation of management, including our President and Chief Executive Officer, and our Vice President of Finance and Administration, of the effectiveness of the design and operation of 26 our disclosure controls and procedures. Based upon that evaluation, our President and Chief Executive Officer and our Vice President of Finance and Administration concluded that our disclosure controls and procedures are effective, providing management with material information relating to the Company that is required to be included in our reports filed or submitted under the Exchange Act on a timely basis. There have been no significant changes in our internal controls or in other factors that could significantly affect internal controls subsequent to the date we carried out our evaluation, including any corrective actions with regard to significant deficiencies and material weaknesses.
