Each provision of this Agreement shall be interpreted in such a manner as to be effective and valid under applicable law, and if any provision of this Agreement is ruled by the Arbitrator or by a court to be prohibited or invalid under 33 <Page> such applicable law, such provision shall be ineffective to the extent of such prohibition or invalidity, and such prohibition or invalidity shall not invalidate the remainder of this Agreement. 7.10 INTEGRATION.

See Schedule 2.6. 2. On March 8, 2001, following a request for investigation by Andrx, DOV received a letter from the Federal Trade Commission ("FTC") stating that it was "conducting a nonpublic investigation to determine whether Biovail Corporation or any other person is engaging in unfair methods of competition" in violation of the Federal Trade Commission Act, and that the "primary focus . . . is the legality of Biovail's recent [Orange Book] listing [of the DOV diltiazem patent]." The stated purpose of the FTC letter is to seek from DOV, on a voluntary, confidential basis, disclosure to the FTC of certain requested information related to the patent. Although the letter states that it should not be viewed as an accusation of wrongdoing, there can be no reasonable assurance as to any course of action the FTC may take with respect to DOV, Biovail, the Biovail License Agreement or any other person. DOV has furnished the FTC, in a timely fashion, all information so requested except, as permitted, attorney-client privileged material so described. On July 24, 2001, the FTC issued a formal subpoena to the Company regarding this matter but indicated that the document production called for could be satisfied by the Company's prior response to an informal FTC request for documents. 3. Under the Joint Development and Operating Agreement, dated as of January 21, 1999, among the Company, among Elan, EIS, DOV Newco and Nascime, (the "JOINT VENTURE"), Elan is permitted to terminate the license if DOV enters into a license agreement with a listed technological competitor--"Biovail" is so listed--provided that such competitor is thereby "materially engaged or involved with the business or development" of DOV. Other change of control termination rights exist in the event a technological competitor acquires at least 10% of the Company's voting stock or otherwise controls or influences in any material respect the management or business of DOV. Biovail neither holds nor has any options to acquire any voting shares of DOV. The Company has a number of compounds and patents and retains substantial control under the Biovail License Agreement to the one patent covered thereby. The Company therefore does not believe that it cedes material control or influence over its business to Biovail under such Agreement. The Biovail License Agreement is structured in a manner similar to that of a joint venture and gives both joint venture partners a veto over major decisions. For these and other reasons, DOV does not believe Elan's consent was required nor does it believe that Elan is entitled to terminate its license as a result of the Company's conclusion of the Biovail License Agreement without such consent. Nonetheless, a waiver from Elan was sought but the parties were unable to reach terms for the grant of such a waiver. Elan has not threatened to terminate the Joint Venture license as a result. If Elan were entitled to and did terminate its Joint Venture license by reason of the Biovail License Agreement, this could lead to a termination of the Joint Venture's business and a termination of the Company's license thereto as well, and each joint venture party would thereupon succeed to its original grant of rights plus the joint venture rights developed that relate predominately to its pre-license rights. <Page> 4. Subsequent to the January 12, 2001, out-licensing of the diltiazem patent, licensee Biovail listed that patent in the FDA's APPROVED DRUG PRODUCTS WITH THERAPEUTIC EQUIVALENCE EVALUATIONS, commonly known as the "ORANGE BOOK," and stated that the diltiazem patent covered Biovail's branded Tiazac formulation. The effect of this filing was to temporarily prevent Biovail's potential competitor, Andrx Pharmaceuticals, Inc. ("ANDRX"), from obtaining FDA approval of its abbreviated new drug application for a generic version of Tiazac and marketing that generic drug. As a result, Andrx filed an action in the U.S. District Court for the Southern District of Florida (the "FLORIDA LITIGATION") (and pending establishment of jurisdiction, a parallel action in the U.S. District Court for the District of Columbia) against Biovail Corporation International and certain U.S. Government parties seeking, among other relief, the de-listing of the diltiazem patent from the Orange Book. Andrx's pleadings in the Florida Litigation included a motion for preliminary injunction to require Biovail to de-list the diltiazem patent from the Orange Book. Andrx's complaint also seeks to (i) invalidate the Company/Biovail License Agreement as an unreasonable restraint of trade in violation of the Sherman Antitrust Act and to enjoin Biovail from fulfilling its obligations under or exercising its rights as a party to that Agreement; (ii) declare that its generic Tiazac formulation does not infringe the diltiazem patent; and (iii) declare the diltiazem patent invalid. In connection with Andrx's motion to de-list the diltiazem patent in the Florida Litigation, the FDA initially filed papers arguing that its duty in listing patents in the Orange Book was simply a ministerial one, and that if there were a dispute between two private parties whether a patent was properly listed in the Orange Book, it was up to those parties to resolve the dispute. However, on February 28, 2001, after reviewing Biovail's submissions, the FDA filed a Change of Position conveying its view, based upon those submissions and the FDA's review of Biovail's own NDA for Tiazac, that the diltiazem patent did not cover an approved formulation of Tiazac and, therefore, was improperly listed in the Orange Book. In its Change of Position, the FDA further stated that it would refrain from taking any unilateral action with regard to de-listing the diltiazem patent until the court ruled on Andrx's then-pending motion for a preliminary injunction. On March 6, 2001, the court in the Florida Litigation denied Andrx's motion for a preliminary injunction to de-list the diltiazem patent. The court held that Andrx had no private cause of action to enforce the provisions of the Hatch-Waxman Act, and that only the federal government had the right to enforce the provisions of the Food, Drug and Cosmetics Act, of which the Hatch-Waxman Act is a part, or to restrain violations of the Food, Drug and Cosmetics Act. According to the court in the Florida Litigation, it is initially solely within the province of the FDA to determine whether a patent should or should not be listed in the Orange Book. Thus, the FDA is now free to exercise its jurisdiction over the propriety of the Orange Book listing of the diltiazem patent and is presumably considering what actions, if any, would be appropriate for it to take in light of the court's March 6, 2001, ruling in the Florida Litigation. The court also ruled that Andrx had presented no evidence in its motion to support an injunction de-listing the <Page> patent based upon alleged violations of federal antitrust or Florida unfair competition laws. That holding did not affect the validity of those claims as alleged in the complaint, only that Andrx had presented no evidence in its preliminary injunction motion to support an injunction based upon those claims. While the court stated that "it is the FDA's job to determine whether to list or de-list a patent," it recognized that if the FDA is unwilling to act on its own, the propriety of the listing can be litigated in connection with a patent infringement suit filed under the Hatch-Waxman procedures (discussed below), which allows the court hearing the patent infringement suit to shorten the 30-month statutory stay. In its pleadings filed in the Florida Litigation, Biovail requested that Andrx provide to it samples of its generic Tiazac for testing in order to determine whether Andrx's product infringes the diltiazem patent. Under the Drug Price Competition and Patent Term Restoration Act of 1984, commonly known as the Hatch-Waxman Act, an applicant for approval of a generic drug must, if it wishes to have its generic application proceed in the face of an Orange Book-listed patent claiming the pioneer drug, certify that its generic drug either does not infringe the patent stated to be applicable to the pioneer drug or that such patent is invalid. This is commonly known as a Paragraph IV certification. The Paragraph IV certification must be sent to the patent holder and the owner of the pioneer drug to which the listed patent is applicable. Approval of the generic drug is then held in abeyance for 45 days to give the patent holder the opportunity to file an action for patent infringement. If a patent infringement suit is filed within the 45-day period, approval for the generic drug is held in abeyance for an additional 30 months or, if earlier, until final resolution of the patent infringement suit. Following Biovail's Orange Book listing that the diltiazem patent covers Tiazac, and its initiation of the Florida Litigation, on February 19, 2001, Andrx filed, under protest, its Paragraph IV certification claiming that its generic Tiazac did not infringe the diltiazem patent and, if the diltiazem patent in fact covered Tiazac, the patent was invalid. Biovail, as the Company's exclusive licensee, and under the Hatch-Waxman Act, had 45 days (until April 9, 2001) to initiate a patent infringement suit against Andrx if it determined that Andrx's generic drug infringes the diltiazem patent and wished to take advantage of the additional 30-month stay on approval of Andrx's generic Tiazac. Biovail filed such an infringement action against Andrx on April 5, 2001, citing the results of its preliminary analysis of Andrx's product and Andrx's failure to dispute that at least some of its product formulation is covered by the diltiazem patent. The Company is not presently a party to any phase of the Andrx-Biovail litigations. The outcome of the pending litigations cannot be predicted with any reasonable degree of assurance. If the diltiazem patent is not removed from the Orange Book, among other steps Andrx could (i) pursue its claims to have the Biovail license agreement invalidated or the diltiazem patent declared invalid and (ii) in response to Biovail's infringement action, claim that its generic drug does not infringe the diltiazem patent or, alternatively, counterclaim that the diltiazem patent is invalid. If the FDA determines to remove the diltiazem patent from the Orange Book, the foregoing steps (i) and (ii) could still be <Page> taken. The fact that Biovail has filed a patent infringement suit would in itself have no effect on the FDA's approval of Andrx's generic Tiazac, and Andrx would be free to market its generic Tiazac unless Biovail were able to obtain a preliminary injunction against such sales in its patent infringement suit. This is not intended as a summary of all litigation alternatives available to Andrx and Biovail. Nor can the effect, if any, of the litigation on the Company be predicted with any reasonable degree of assurance. It is possible that any one or more of the following could occur: (i) the Biovail License Agreement, if invalidated, would eliminate the Company's right to receive clinical development, milestone, royalty payments and other benefits accruing to the Company thereunder; (ii) Biovail having filed an infringement action against Andrx, the Company may be responsible for certain of Biovail's legal expenses, under the terms of the Biovail License Agreement, capped at $1.5 million, with regard to litigating its claim that Andrx's Tiazac generic infringes the diltiazem patent; (iii) if, as a result of a court or other ruling, the diltiazem patent is declared invalid, the Company would suffer the events noted in clause (i) as if the License Agreement were invalidated as well as the loss of any other potential value that could have been derived from the diltiazem patent; and (iv) the Company may be a necessary party to any litigation regarding the enforcement or validity of its diltiazem patent. 5. Pursuant to the Agreement, dated as of June 20, 2000, among the Company, EIS and holders of the Series C Preferred, the Company is required to make certain payments to the holders of the Series C Preferred in connection with a liquidation or certain other events stated therein. <Page> SCHEDULE 2.7 - UNDISCLOSED LIABILITIES (REVISED) 1. See Schedule 2.6. 2. On March 8, 2001, following a request for investigation by Andrx, DOV received a letter from the Federal Trade Commission ("FTC") stating that it was "conducting a nonpublic investigation to determine whether Biovail Corporation or any other person is engaging in unfair methods of competition" in violation of the Federal Trade Commission Act, and that the "primary focus . . . is the legality of Biovail's recent [Orange Book] listing [of the DOV diltiazem patent]." The stated purpose of the FTC letter is to seek from DOV, on a voluntary, confidential basis, disclosure to the FTC of certain requested information related to the patent. Although the letter states that it should not be viewed as an accusation of wrongdoing, there can be no reasonable assurance as to any course of action the FTC may take with respect to DOV, Biovail, the Biovail License Agreement or any other person. DOV has furnished the FTC, in a timely fashion, all information so requested except, as permitted, attorney-client privileged material so described. On July 24, 2001, the FTC issued a formal subpoena to the Company regarding this matter but indicated that the document production called for could, if responsive, be satisfied by the Company's reply to the earlier informal FTC request for documents. 3. Under the Joint Development and Operating Agreement, dated as of January 21, 1999, among the Company, among Elan, EIS, DOV Newco and Nascime, (the "JOINT VENTURE"), Elan is permitted to terminate the license if DOV enters into a license agreement with a listed technological competitor--"Biovail" is so listed--provided that such competitor is thereby "materially engaged or involved with the business or development" of DOV. Other change of control termination rights exist in the event a technological competitor acquires at least 10% of the Company's voting stock or otherwise controls or influences in any material respect the management or business of DOV. Biovail neither holds nor has any options to acquire any voting shares of DOV. The Company has a number of compounds and patents and retains substantial control under the Biovail License Agreement to the one patent covered thereby. The Company therefore does not believe that it cedes material control or influence over its business to Biovail under such Agreement. The Biovail License Agreement is structured in a manner similar to that of a joint venture and gives both joint venture partners a veto over major decisions. For these and other reasons, DOV does not believe Elan's consent was required nor does it believe that Elan is entitled to terminate its license as a result of the Company's conclusion of the Biovail License Agreement without such consent. Nonetheless, a waiver from Elan was sought but the parties were unable to reach terms for the grant of such a waiver. Elan has not threatened to terminate the Joint Venture license as a result. If Elan were entitled to and did terminate its Joint Venture license by reason of the Biovail License Agreement, this could lead to a termination of the Joint Venture's business and a termination of the Company's license thereto as well, and each joint venture party would thereupon succeed to its original grant of rights plus the joint venture rights developed that relate predominately to its pre-license rights. <Page> 4. Subsequent to the January 12, 2001, out-licensing of the diltiazem patent, licensee Biovail listed that patent in the FDA's APPROVED DRUG PRODUCTS WITH THERAPEUTIC EQUIVALENCE EVALUATIONS, commonly known as the "ORANGE BOOK," and stated that the diltiazem patent covered Biovail's branded Tiazac formulation. The effect of this filing was to temporarily prevent Biovail's potential competitor, Andrx Pharmaceuticals, Inc. ("ANDRX"), from obtaining FDA approval of its abbreviated new drug application for a generic version of Tiazac and marketing that generic drug. As a result, Andrx filed an action in the U.S. District Court for the Southern District of Florida (the "FLORIDA LITIGATION") (and pending establishment of jurisdiction, a parallel action in the U.S. District Court for the District of Columbia) against Biovail Corporation International and certain U.S. Government parties seeking, among other relief, the de-listing of the diltiazem patent from the Orange Book. Andrx's initial pleadings in the Florida Litigation included a motion for preliminary injunction to require Biovail to de-list the diltiazem patent from the Orange Book, which on March 6, 2001, was denied on the grounds that Andrx had no private right of action to enforce the provisions of the Drug Price Competition and patent Term Restoration Act of 1984, commonly known as the Hatch-Waxman Act, and that only the federal government had the right to enforce the provisions of the Food, Drug and Cosmetics Act, of which the Hatch-Waxman Act is a part, or to restrain violations of the Food, Drug and Cosmetics Act. Under the Hatch-Waxman Act, an applicant for approval of a generic drug must, if it wishes to have its generic application proceed in the face of an Orange Book-listed patent claiming the pioneer drug, certify that its generic drug either does not infringe the patent stated to be applicable to the pioneer drug or that such patent is invalid. This is commonly known as a Paragraph IV certification. The Paragraph IV certification must be sent to the patent holder and the owner of the pioneer drug to which the listed patent is applicable. Approval of the generic drug is then held in abeyance for 45 days to give the patent holder the opportunity to file an action for patent infringement. If a patent infringement suit is filed within the 45-day period, approval for the generic drug is held in abeyance for an additional 30 months or, if earlier, until final resolution of the patent infringement suit. Following Biovail's Orange Book listing that the diltiazem patent covers Tiazac, and Andrx's initiation of the Florida Litigation, on February 19, 2001, Andrx also filed, under protest, a Paragraph IV certification under the Hatch-Waxman Act claiming that its generic drug did not infringe the diltiazem patent and, if the diltiazem patent in fact covered Tiazac, the patent was invalid. As noted above, Biovail, as the Company's exclusive licensee, had, under the Hatch-Waxman Act, 45 days (until April 9, 2001) to initiate a patent infringement suit against Andrx if it determined that Andrx's generic drug infringes the diltiazem patent and wished to avail itself of the additional 30-month stay on approval of Andrx's generic drug. Biovail filed such an infringement action against Andrx on April 5, 2001 (the "INFRINGEMENT LITIGATION"). <Page> In both the Florida Litigation and the Infringement Litigation further pleadings were filed, including motions by Andrx for partial summary judgment that sought (i) de-listing of the diltiazem patent from the Orange Book and (ii) reduction or elimination of the 30-month stay imposed under the Hatch-Waxman Act. Andrx also filed an amended complaint in the Florida Litigation, which sought, among other relief, (i) delisting of the diltiazem patent from the Orange Book; (ii) invalidation the Biovail License Agreement based upon the assertion that it constituted an unreasonable restraint of trade or that such agreement constituted a conspiracy or an attempt to monopolize the market for calcium channel blockers, in each case in violation of the Sherman Antitrust Act, and to enjoin Biovail from fulfilling its obligations under or exercising its rights as a party to the such agreement; (iii) injunctive relief against Biovail for alleged tortious interference with business relations, for alleged conduct constituting negligence per se and for alleged acts stated to be in violation of Florida statutory and common law for unfair and deceptive trade practices; (iv) a declaration that its Andrx's generic Tiazac formulation does not infringe the diltiazem patent; (v) a declaration that the diltiazem patent is invalid; and (vi) a declaration that the 30-month stay imposed under the Hatch-Waxman Act be reduced or eliminated. Following numerous other motions filed in the aforementioned actions, including a motion to consolidate the Florida Litigation and the Infringement Litigation, which was granted, the Florida Court, on September 19, 2001, issued an opinion in the case that had the following results: (i) Andrx's motion for partial summary judgment to delist the diltiazem patent from the Orange Book was denied based upon the reasoning employed in the Florida Litigation at the preliminary injunction stage, namely, that there exists no private right of action outside of litigation instituted under the Hatch-Waxman Act; (ii) Andrx's state law claims for unfair and deceptive trade practices, tortious interference with business relations and negligence per se, which, according to the court, all rely on the existence of the patent listing requirements of the Hatch-Waxman Act, were dismissed due to their being preempted by federal law; (iii) Andrx's antitrust claims for conspiracy to restrain trade, conspiracy to monopolize, attempted monopolization and monopolization under the Shearman Antitrust Act, were held to survive Biovail's motions to dismiss on the ground that at this stage of the litigation Andrx had stated a claim sufficient to seek such requested relief; (iv) Andrx's claims for a declaration of noninfringement of the diltiazem patent and a declaration that the diltiazem patent is invalid were dismissed in the Florida Litigation as being premature owing to the court's previous decision that a private right of action does not exist outside of litigation instituted under the Hatch-Waxman Act, but were allowed to proceed as counterclaims in the Infringement Litigation; and (v) Andrx's motion for partial summary judgment to shorten or eliminate the 30-month stay under the Hatch-Waxman Act was granted, with the court ruling that the statutory stay should end on September 27, 2001, and that the FDA should approve Andrx's generic, based upon the court's finding that Biovail's actions in listing the diltiazem patent in the Orange Book and reformulating Tiazac to fall under the claims of the diltiazem patent ran afoul of its obligation to reasonably cooperate in expediting the (infringement) action under the Hatch-Waxman Act. Biovail has filed a notice of appeal from the court's ruling to shorten the 30-month statutory stay. <Page> The ultimate outcome of the consolidated case cannot be predicted with any reasonable degree of assurance. According to Andrx, the FDA has advised it that certain dosages of its generic Tiazac are ready for FDA approval, but that it requires additional information related to other strengths in order to make its approval determinations. Biovail has disputed the bioequivalence to Tiazac of the Andrx's generic. Nonetheless, it appears that Andrx's generic Tiazac will eventually be approved by the FDA and marketed for sale, thereby becoming a competitor in the market with Biovail's Tiazac. It is unclear at this stage what legal action, if any, Andrx will take. It is possible that Andrx could pursue any of or all the claims that have survived this most recent decision. Andrx could pursue its claims to have the Biovail license agreement invalidated based upon its assertions of alleged violations under the Shearman Antitrust Act, or Andrx could pursue its counterclaims that the DOV diltiazem patent is invalid or that its generic drug does not infringe the DOV diltiazem patent. The aforementioned options are not intended as a summary of all litigation alternatives available to Andrx and Biovail. The Company is not a party to any phase of the Andrx-Biovail litigation. Likewise, the effect, if any, of the litigation on the Company cannot be predicted with any reasonable degree of assurance. The September 19, 2001, opinion, while dismissing some claims, advances certain other claims against Biovail implicating the diltiazem patent and, arguably, could be viewed as increasing the risk to the Company that any one or more of the following could occur: (i) the Biovail License Agreement, if invalidated, would eliminate the Company's right to receive clinical development, milestone, royalty payments and other benefits accruing to the Company thereunder; (ii) Biovail having filed an infringement action against Andrx, the Company may be responsible for certain of Biovail's legal expenses, under the terms of the Biovail License Agreement, capped at $1.5 million, with regard to litigating its claim that Andrx's Tiazac generic infringes the diltiazem patent; (iii) if, as a result of a court or other ruling, the diltiazem patent is declared invalid, the Company would suffer the events noted in clause (i) as if the License Agreement were invalidated as well as the loss of any other potential value that could have been derived from the diltiazem patent; and (iv) the Company may be a necessary party to any litigation regarding the enforcement or validity of its diltiazem patent. Since, however, the Biovail License Agreement does not cover Tiazac, any capture by Andrx or others of Biovail's Tiazac market will not in itself have a direct impact on DOV's royalty or milestone revenues expected thereunder unless the DOV diltiazem patent or the Biovail License Agreement is invalidated by the court. 5. Pursuant to the Agreement, dated as of June 20, 2000, among the Company, EIS and holders of the Series C Preferred, the Company is required to make certain payments to the holders of the Series C Preferred in connection with a liquidation or certain other events stated therein. <Page> SCHEDULE 2.8(b) - CERTAIN DEVELOPMENTS None. <Page> SCHEDULE 2.8(f) - CERTAIN DEVELOPMENTS Pursuant to the Duncan Agreement, Ms. Duncan shall become the Company's Chief Financial Officer and Vice President/Finance.

CERTAIN TRANSACTIONS STRUCTURE OF JOINT VENTURE WITH ELAN CORPORATION, PLC On January 21, 1999, the Company, Elan and Elan International Services, Ltd., closed the Joint Venture transaction providing for (a) the formation of DOV Newco, Ltd., a Bermuda limited company (renamed DOV Bermuda, Ltd.), (b) the formation of Nascime, Ltd. (an Irish private limited company) to which the Company and Elan licensed certain technology and (c) equity and debt financing by Elan International of the Company's required participation in the Joint Venture. FORMATION AND CAPITALIZATION OF JOINT VENTURE. The Company, Elan and Elan International established the Joint Venture as the vehicle to develop, exploit and commercialize two of the Company's compounds, DOV 220,075 <Page> (the analgesic) and DOV 273,547 (the anxiolytic) using Elan's proprietary controlled release formulations (the "Products"). The Joint Venture's initial capitalization is $10 million, with the Company subscribing for 80.1% of the Joint Venture's capital stock for $8.01 million and Elan International subscribing for the remaining 19.9% for $1.99 million. The Company and Elan International have preemptive rights to participate in any equity offering by the Joint Venture in order to maintain their respective equity positions. The Joint Venture shares are subject to certain transfer restrictions. LICENSES TO JOINT VENTURE. Pursuant to the Joint Venture transaction, Elan granted the Joint Venture a non-exclusive license for $10 million to use its proprietary controlled release formulations in connection with the development and commercialization of the Products. For its part, the Company has granted the Joint Venture an exclusive sublicense to use DOV 220,075 (analgesic) and DOV 273,547 (anxiolytic). The Joint Venture will remit certain milestone payments to the Company to enable it to meet its milestone obligations pursuant to its license agreement with ACY, and the Joint Venture will pay both the Company and Elan royalties on net sales relating to DOV 220,075 and DOV 273,547. The Company (rather than the Joint Venture) is responsible for the payment of such royalties and other obligations. The Company retains the right to intravenous administration of the compounds, which is not included in the Joint Venture. MEANS OF COMPANY FUNDING OF JOINT VENTURE. The Company has funded its initial investment in the Joint Venture by issuing to Elan International the Exchangeable Debt, a convertible and exchangeable debt instrument in the principal amount of $8.01 million. The Exchangeable Debt has a term of six years from the Joint Venture closing and bears interest at 7% per annum, compounded semi-annually. The Exchangeable Debt is not prepayable without Elan International's approval, and interest accrues thereon and is added to principal. The Exchangeable Debt is senior to any other Company debt provided that the Company may issue senior institutional debt up to $1 million and may issue unlimited institutional debt on a PARI PASSU basis. In connection with the subsequent Biotechnology Value Fund Series C Preferred financing (see below), Elan International agreed that the Series C Preferred would be treated upon liquidation on a PARI PASSU basis with the principal amount of the Exchangeable Debt. ELAN INTERNATIONAL'S RIGHT TO INCREASE OWNERSHIP OF JOINT VENTURE. Elan International has the right to exchange the principal amount of the Exchangeable Debt into the number of shares of the Joint Venture capital stock that would increase its equity ownership in the Joint Venture to 50% from 19.9%. Upon exercise of such exchange right the accrued interest would remain an obligation of the Company, unless Elan International determines to exercise its conversion right (as described below) with respect thereto. Following exercise of the exchange right, Elan International would be required to reimburse the Company for a portion of total development costs paid by the Company to the Joint Venture so that the Company and Elan International funding from the Joint Venture closing is equal. COMPANY STOCK PURCHASE BY ELAN INTERNATIONAL. In connection with the Joint Venture transaction, Elan International purchased $3 million of the Company's Common Stock (324,090 shares) and Series B Preferred (354,643 shares, convertible on a one-for-one basis into Common Stock; preferred neither as to dividends nor upon liquidation) at $4.42 per share or an aggregate of 678,733 shares and the Company issued Elan International a six-year warrant to acquire up to an additional 75,000 shares of Common Stock at an exercise price of $5.52. Elan International has agreed that so long as the Exchangeable Debt and the Line of Credit Debt remain outstanding Elan International will own less than 10% of the Company's voting stock. While Elan International received anti-dilution protection against securities offerings below $3.68 per share of Common Stock, this protection expired in July 2000. If, in addition to its original stock purchase, Elan International elects to exercise (a) the conversion right with respect to the Exchangeable Debt at the end of its term (January 2005), (b) the conversion right with respect to the Line of Credit Debt at the end of its term (January 2005), assuming a maximum principal amount of approximately $2.4 million, that is, no further draw-downs through the six year term, and (c) its 75,000 warrants, it will have an equity position of approximately 37% and 34.5% of the Company (assuming a closing on the Minimum and Maximum Amounts, respectively, and no additional equity financing during the six-year term). ELAN INTERNATIONAL EXCHANGEABLE DEBT CONVERSION RIGHT. Beginning two years after the Joint Venture closing, that is, in January 2001, Elan International has the right to convert the Exchangeable Debt, together with <Page> accrued interest, into the number of shares of the Company's Common Stock or Non-Voting Stock at a conversion rate of $6.44. ONGOING JOINT VENTURE FUNDING. The Company and Elan International are required to contribute all necessary capital to support the Joint Venture's expenditures in accordance with their respective equity ownership of 80.1% and 19.9% in favor of the Company. Funding for the Company's capital contributions will be made available not only through the Joint Venture financing but, if necessary, through the $7 million Line of Credit Debt provided by Elan International. The Line of Credit Debt will become due six years from the Joint Venture closing and bear interest at 10% per annum, compounded semi-annually. The Line of Credit Debt will not be prepayable without Elan International's approval, and interest will accrue thereon and be added to principal. Elan International has the right to convert the Line of Credit Debt, together with accrued interest, into the number of shares of the Company's Common Stock or Non-Voting Stock at a conversion rate of $5.52. Application of funds from the Line of Credit Debt is restricted to the Joint Venture research and development costs. If either the Company or Elan International decides not to fund a Product that the Joint Venture has slated for funding, the party contributing capital toward such funding has the right to cause the Joint Venture to transfer such Product to it on standard and customary market terms. If one party but not the other ceases making capital contributions to the Joint Venture adequate to develop and commercialize the Products, the contributing party will acquire additional equity in the Joint Venture at reduced cost to compensate it for the additional capital contributed. NO COMPETITION. With certain exceptions, the Company, Elan and Elan International are restricted from competing with the Joint Venture by developing or commercializing a product with the same active ingredient as a Product. In addition, the parties are subject to certain change of control provisions. The Company has retained the right to intravenous formulations. JOINT VENTURE BOARD. The Joint Venture's board of directors has been comprised initially of five members, a majority of whom were appointed by the Company. However, Elan International's agreement will be required for all material acquisitions and specified material decisions. The Joint Venture board is required to appoint management as well as research and development committees. RESEARCH. The Company and Elan are required to undertake certain research and development work relating to the Products for which the Joint Venture will reimburse the Company and Elan for their actual costs incurred plus an additional 40% of such costs. Subcontracted services will be reimbursed at cost. It is estimated that the Joint Venture will require up to $10 million within the first 30 months of the Joint Venture closing to commence development of the Products. ADDITIONAL ELAN INTERNATIONAL RIGHTS. Elan International has a preemptive right associated with its Common Stock and Non-Voting Stock exercisable for four years from the Joint Venture closing to participate in any equity financing by the Company to enable Elan International to maintain its PRO RATA equity interest in the Company attributable to such Stock. In addition, so long as Elan International holds at least a 10% equity position in the Company, it will be entitled to elect one member to the Company's board of directors. REGISTRATION RIGHTS. The Company, with respect to the Joint Venture capital stock, and Elan International, with respect to both Company and the Joint Venture capital stock, have one demand and unlimited piggyback registration rights. The demand registration right is not exercisable until six months after an initial public offering. OPERATIONS UNDER JOINT VENTURE The board of directors of the Joint Venture is comprised of five members, four appointed by the Company and one by Elan. Research is managed by a committee on which the Company and Elan have equal representation. In April 1999, three months after the Joint Venture formation, the board of directors approved a business plan presented by this committee. According to this business plan, Elan would be responsible for development of the controlled release formulation and the Company would be responsible for clinical development of the two Joint Venture compounds. <Page> BIOTECHNOLOGY VALUE FUND AND RESERVOIR CAPITAL In January 2000, the Company agreed to raise equity capital from Biotechnology Value Fund, L.P. and affiliates.

Such investors acquired the Company's Series C Preferred, convertible at $4.04 per share.
