INTERNEURON shall notify URIACH in writing within thirty (30) days after the achievement of each milestone (ninety (90) days for milestone (f)), and such notice shall be accompanied by payment of the appropriate milestone payment. Milestone payments made under Section 5.2 (c), (d) and/or (e) shall be creditable against payments required under Section 5.3.1 or 5.3.2 of this Agreement. 5.3. Royalties and Other Payments. 5.3.1. Royalties Payable By INTERNEURON. (i) Subject to the terms and conditions of this Agreement, and in further consideration of the rights granted by URIACH hereunder, INTERNEURON shall pay to URIACH royalties in an amount equal to [*] of Net Sales in each Royalty Year by INTERNEURON or its Affiliates in the United States of America during the period mentioned in subparagraph (iii) below. (ii) Subject to the terms and conditions of this Agreement, and in further consideration of the rights granted by URIACH hereunder, INTERNEURON shall pay to URIACH royalties equal to [*] of Net Sales in each Royalty Year by INTERNEURON or its Affiliates in each country in the Territory other than the United States of America during the period mentioned in subparagraph (iii) below. (iii) Royalties on Net Sales at the rates set forth in (i) and (ii) above shall accrue as of the date of First Commercial Sale of Product in the applicable country and shall continue and accrue on Net Sales on a country-by-country basis until the later of (a) the expiration of the last to expire patent included in the Patent Assets in such country or (b) ten (10) years from the *Confidential Treatment Requested Page 19 of 46 date of First Commercial Sale in such country. Thereafter, INTERNEURON shall be relieved of any royalty payment under this Section 5.3. (iv) Notwithstanding the provisions of Subsections (i),(ii) and (iii) above, no royalties shall be payable in respect of Net Sales of any given Product in any given country of the Territory as of and after the date on which a Generic Drug of such Product is sold in the applicable country in the Territory. (v) The payment of royalties set forth above shall be subject to the following conditions: (A) only one payment shall be due with respect to the same unit of Product; (B) no royalties shall accrue on the disposition of Product by INTERNEURON, Affiliates or sublicensees as samples (promotion or otherwise) or as donations (for example, to non-profit institutions or government agencies) or to clinical trials; and (C) URIACH shall be responsible for payment of any royalties or other obligations owed by URIACH to any Third Party. 5.3.2. Payments in the Event of Sublicense. (i) In the event INTERNEURON enters into a sublicense with a Third Party or Third Parties under Section 2.3 of this Agreement, then in lieu of INTERNEURON paying URIACH the royalty payments set forth in Section 5.3.1 above, INTERNEURON shall pay URIACH [*] of royalty payments received by INTERNEURON ("INTERNEURON Royalties") which shall at all times be based on net sales of Product by Sublicensee(s) (such net sales to be defined in any sublicense agreement in terms materially consistent with the definition of Net Sales contained in this Agreement). If INTERNEURON enters into a sublicense with a Third Party under Section 2.3 of this Agreement for the United States prior to completion of the Phase 2 Clinical Trial, INTERNEURON shall pay URIACH [*] of INTERNEURON Royalties received from such Sublicensee. Payments shall be required under this Section 5.3.2(i) for so long as INTERNEURON is receiving INTERNEURON Royalties. * Confidential Treatment Requested Page 20 of 46 (ii) INTERNEURON shall exercise commercially reasonable efforts to collect INTERNEURON Royalties, shall not waive any right to receive such INTERNEURON Royalties, and shall not assign such right or otherwise dispose of it without first having obtained URIACH's written consent, except in accordance with the terms of or as contemplated by this Agreement. (iii) INTERNEURON shall also pay URIACH [*] of Sales Based Milestone Payments (as defined in the next sentence). Sales Based Milestone Payments shall mean those payments received by INTERNEURON from a Sublicensee that are contingent upon the Sublicensee's achievement of specifed levels of net sales of Product; provided, however, that any amounts payable to URIACH under this Section 5.3.2 (iii) shall be reduced by the [*] milestone payment payable by INTERNEURON to URIACH under Section 5.2 (f). Payment under this Section 5.3.2 (iii) shall be made by INTERNEURON not later than thirty (30) days after having received the Sales Based Milestone Payment from its Sublicensee. 5.3.3. Compulsory Licenses. If a compulsory license is granted to a Third Party with respect to Product in any country in the Territory with a royalty rate lower than the royalty rate provided by Section 5.3.1, then the royalty rate to be paid by INTERNEURON on Net Sales in that country under Section 5.3.1 shall be reduced to the rate paid by the compulsory Third Party licensee. 5.3.4. Third Party Licenses. If INTERNEURON is prevented from developing, making, having made, using, selling or importing any Compound included in the Patent Assets in any country of the Territory on the grounds that by doing so INTERNEURON or any Sublicensee would infringe patent rights held by a Third Party in said country, and if INTERNEURON wishes to obtain a license from such Third Party, then [*] of any royalties paid under such Third Party patent licenses by INTERNEURON in such country for such Calendar Quarter shall be creditable against the royalty payable to URIACH by INTERNEURON in consideration for Net Sales of said Product in such country; provided, however that this provision shall not apply if (i) the Third Party License is to be otained in any country which is not listed under the heading "Country" in Schedule 1.24 and/or (ii) the priority date of the patent rights which are claimed to be infringed is any date after the Effective Date. 5.4. Reports, Payment of Royalty. During the term of the Agreement for so long as royalty payments are due, INTERNEURON shall furnish to URIACH a quarterly written report for the Calendar Quarter showing the sales of all Products subject to royalty payments sold by INTERNEURON and its Sublicensees during the reporting period and the royalties payable under this Agreement. Reports shall be due on the seventy-fifth (75/th/) *Confidential Treatment Requested Page 21 of 46 day following the close of each Calendar Quarter. Royalties shown to have accrued by each royalty report, if any, shall be due and payable on the date such royalty report is due. INTERNEURON shall keep complete and accurate records in sufficient detail to enable the royalties hereunder to be determined. 5.5. Audits. Upon the written request of URIACH and not more than once in each Calendar Year, INTERNEURON shall permit an independent certified public accounting firm selected by URIACH and reasonably acceptable to INTERNEURON to have access during normal business hours, upon ten-days notice to INTERNEURON, to such of the records of INTERNEURON as may be reasonably necessary to verify the accuracy of the royalty reports hereunder for any Royalty Year ending not more than thirty-six (36) months prior to the date of such request. The accounting firm shall disclose to URIACH only whether the royalty reports are correct or incorrect and the specific details concerning any discrepancies. 5.5.1. If such accounting firm concludes that additional royalties were owed during such period, INTERNEURON shall pay the additional royalties within sixty (60) days of the date URIACH delivers to INTERNEURON such accounting firm's written report so concluding; provided however, that, in the event that INTERNEURON shall not be in agreement with the conclusion of such report (a) INTERNEURON shall not be required to pay such additional royalties and (b) such matter shall be resolved pursuant to the provisions of Section 10.5 herein. In the event such accounting firm concludes that amounts were overpaid by INTERNEURON during such period, INTERNEURON shall have a credit against future royalties payable to URIACH in the amount of such overpayment. The fees charged by such accounting firm shall be paid by URIACH; provided, however, that if an error in favor of URIACH of more than the greater of (i) [*] or (ii) [*] of the royalties due hereunder for the period being reviewed is discovered, then the fees and expenses of the accounting firm shall be paid by INTERNEURON. 5.5.2. Upon the expiration of thirty-six (36) months following the end of any Royalty Year the calculation of royalties payable with respect to such year shall be binding and conclusive upon the Parties , and each Party shall thereafter be released from any liability or accountability to the other Party with respect to royalties for such year. 5.5.3. URIACH and INTERNEURON shall treat all financial information subject to review under this Section 5.5. or under any sublicense agreement in accordance with the confidentiality provisions of this Agreement. *Confidential Treatment Requested Page 22 of 46 5.6. Payment Exchange Rate. All payments to URIACH under this Agreement shall be made in United States dollars. In the case of sales outside the United States, the rate of exchange to be used to convert the amount of currency into United States dollars shall be the one published in the Wall Street Journal, Eastern edition, on the last day of the Calendar Quarter where such sales shall be reported as set forth in Section 5.4. above, and royalties shall be paid in United States dollars in accordance with such converted amount. 5.7. Tax Withholding. If laws, rules or regulations require withholding of income taxes or other taxes imposed upon payments set forth in this Article V, URIACH shall provide INTERNEURON, prior to any such payment, annually or more frequently if required, with all forms or documentation required by any applicable taxation laws, treaties or agreements to such withholding or as necessary to claim a benefit thereunder (including, but not limited to Form W-8BEN or any successor forms) and INTERNEURON shall make such withholding payments as required and subtract such withholding payments from the payments set forth in this Article V. INTERNEURON will use commercially reasonable efforts consistent with its usual business practices and cooperate with URIACH to ensure that any withholding taxes imposed are reduced as far as possible under the provisions of the current or any future taxation treaties or agreements between foreign countries. 5.8. Exchange Controls. Notwithstanding any other provision of this Agreement, if at any time legal restrictions prevent the prompt remittance of part or all of the royalties with respect to Net Sales in any country, payment shall be made through such lawful means or methods as INTERNEURON may determine. When in any country the law or regulations prohibit both the transmittal and deposit of royalties on sales in such a country, royalty payments shall be suspended for as long as such prohibition is in effect (and such suspended payments shall not accrue interest), and promptly after such prohibition ceases to be in effect, all royalties that INTERNEURON or its Affiliates or sublicensees would have been obligated to transmit or deposit, but for the prohibition, shall be deposited or transmitted, as the case may be, to the extent allowable (with any interest earned on such suspended royalties which were placed in an interest-bearing bank account in that country, less any transactional costs). If the royalty rate specified in this Agreement should exceed the permissible rate established in any country, the royalty rate for sales in such country shall be adjusted to the highest legally permissible or government-approved rate. ARTICLE VI REPRESENTATIONS AND WARRANTIES 6.1. URIACH. Representations and Warranties. URIACH represents and warrants to INTERNEURON that as of the Effective Date: Page 23 of 46 (a) URIACH is unaware of any reason that the presumption of validity would not apply to the issued patents included in the Patent Assets or that a court of competent jurisdiction would, upon investigation, find such patents invalid or unenforceable.

Except as set forth in this Agreement, this Agreement shall not be affected by the status of the Patent Assets, and the failure to obtain any patent or the fact that any Patent Assets may be declared invalid or unenforceable shall not provide a basis for termination of this Agreement under Section 8.3 of this Agreement nor shall it entitle any party to demand a revision or to renegotiate the terms of this Agreement; (b) this Agreement has been duly executed and delivered by URIACH and constitutes legal, valid, and binding obligations enforceable against URIACH in accordance with its terms; (c) no approval, authorization, consent, or other order or action of or filing with any court, administrative agency or other governmental authority is required for the execution and delivery by URIACH of this Agreement or the consummation by URIACH of the transactions contemplated hereby; (d) URIACH has the full corporate power and authority to enter into and deliver this Agreement, to perform and to grant the licenses granted under Article II hereof and to consummate the transactions contemplated hereby; all corporate acts and other proceedings required to be taken to authorize such execution, delivery, and consummation have been duly and properly taken and obtained; (e) URIACH has not previously assigned, transferred, conveyed or otherwise encumbered its right, title and interest in the Patent Assets or URIACH Know-How or entered into any agreement with any Third Party which is in conflict with the rights granted to INTERNEURON pursuant to this Agreement; (f) it is the sole and exclusive owner under the Patent Assets and URIACH Know-How, all of which are free and clear of any liens, charges and encumbrances, and no other person, corporate or other private entity, or governmental or university entity or subdivision thereof has any claim of ownership with respect to the Patent Assets or URIACH Know-how, whatsoever; (g) To the best of URIACH's knowledge, the development, manufacture, use and sale of Compound and Products do not infringe any patent rights owned or possessed by any Third Party; Page 24 of 46 (h) Schedule 1.24 is a complete and accurate list of all patents and patent applications in the Territory relating to Compound or Product owned by URIACH or to which URIACH has the right to license; (i) there are no claims, judgments or settlements against or owed by URIACH or pending or, to the best of its knowledge, threatened claims or litigation relating to the Patent Assets; (j) URIACH has disclosed to INTERNEURON all relevant information known by it regarding the Patent Assets and URIACH Know-How reasonably related to the activities contemplated under this Agreement; (k) URIACH is not aware of any contract research organization, corporation, business entity or individual which have been involved in any studies conducted for the purpose of obtaining regulatory approvals having been debarred individuals or entities within the meaning of 21 U.S.C. section 335(a) or (b); (l) in connection with development of Compound and Product, URIACH has complied in all material respects with applicable Spanish laws and regulations; (m) the Compound and/or Product manufactured by URIACH at the time of delivery ex-works shall conform to the Specifications and be manufactured, tested and stored in accordance with the Specifications and with cGMPs (or if intended for shipment outside the United States, any equivalent laws, rules or regulations), and other applicable laws and regulations; (n) URIACH has manufacturing facilities and equipment necessary to manufacture Product pursuant to Specifications and otherwise perform URIACH's supply obligations hereunder, and the URIACH manufacturing facility, process and equipment validation to be used in the manufacture of Compound or Product comply with cGMPs and other applicable laws and regulations; and (o) AT THE TIME OF DELIVERY EX-WORKS, THE PRODUCT SHALL NOT (I) BE ADULTERATED OR MISBRANDED WITHIN THE MEANING OF THE FEDERAL FOOD DRUG AND COSMETIC ACT OF 1934, AND THE RULES AND REGULATIONS PROMULGATED THEREUNDER, OR ANY SUCCESSOR ACT, AS THE SAME SHALL BE IN EFFECT FROM TIME TO TIME OR WITHIN THE MEANING OF ANY APPLICABLE LAW, RULES OR REGULATIONS, OR (II) BE PROHIBITED FROM BEING INTRODUCED INTO INTERSTATE COMMERCE. Page 25 of 46 (p) EXCEPT AS EXPRESSLY SET FORTH IN THIS SECTION 6.1., URIACH HEREBY DISCLAIMS ANY AND ALL WARRANTIES WITH RESPECT TO THE URIACH INTELLECTUAL PROPERTY, THE COMPOUND AND THE PRODUCT INCLUDING WITHOUT LIMITATION ANY IMPLIED WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. Except as otherwise provided in this Agreement and, if URIACH exercises any of the URIACH Options, the agreements referred to in Section 2.4, INTERNEURON shall be responsible for all matters concerning development of the Products and the use, importation, commercialization, distribution and sale of Products in the Territory, including compliance with any and all relevant applicable laws, and any product liability claims. 6.2.

URIACH shall file and prosecute patent applications included in the Patent Assets in any country in which the patents included on Schedule 1.24 have been filed and are being prosecuted until such time as underlying patents included in the Patent Assets issue. After the issuance of patents included in the Patent Assets, INTERNEURON shall maintain the Patent Assets in URIACH's name and, upon INTERNEURON's request, URIACH shall reasonably cooperate in the maintenance of such patents. URIACH shall be responsible for the payment of all patent filing and prosecution costs incurred prior to the date of issuance of any patent and INTERNEURON shall be responsible for the payment of all Page 26 of 46 patent maintenance costs incurred after the date of issuance of the applicable patent except that, (i) in the event URIACH exercises its Spain Option, URIACH shall be responsible for and shall reimburse INTERNEURON for 50% of the patent maintenance costs in Spain incurred by INTERNEURON after the date URIACH exercises the Spain Option; and (ii) in the event URIACH exercises the CA/SA Option, URIACH shall be responsible for and shall reimburse INTERNEURON for all patent maintenance costs incurred by INTERNEURON in the Central and South American Countries after the date URIACH exercises the CA/SA Option. In any event, each Party shall be responsible for the payment of legal fees incurred by it associated with its respective activities under this Section 7.1. If URIACH elects not to file or prosecute a patent application included in the Patent Assets in any country in which the patents included on Schedule 1.24 have been filed and are being prosecuted, it shall provide INTERNEURON with written advance notice sufficient to avoid any loss or forfeiture, and INTERNEURON shall have the right, at its sole expense, to file or prosecute such patent application in INTERNEURON's name and URIACH shall assign to INTERNEURON all of URIACH's right, title and interest in and to such Patent Assets and shall reimburse INTERNEURON for all patent filing and prosecution costs incurred by INTERNEURON in connection with such patent application, it being understood that this shall not affect INTERNEURON's obligations to pay royalties as set forth in this Agreement. Upon INTERNEURON's request, URIACH shall reasonably cooperate in the filing and prosecution of such patent application. If INTERNEURON elects not to maintain a patent included in the Patent Assets, it shall provide URIACH with written advance notice sufficient to avoid any loss or forfeiture, and URIACH shall have the right, at its sole expense, to maintain such patent. Upon URIACH's request, INTERNEURON shall reasonably cooperate in the maintenance of such patent. If INTERNEURON's election refers to Patent [*] or its equivalent in any specific country, then INTERNEURON's rights under this Agreement shall terminate regarding such country, which shall be then excluded from the definition of "Territory", if URIACH so wishes. In this event, the provisions of Section 8.4.(b) shall apply with respect to such country. 7.2. Patent Office Proceedings. Each Party shall inform the other Party of any request for, filing, or declaration of any proceeding before a patent office seeking to protest, oppose, cancel, reexamine, declare an interference proceeding, initiate a conflicts proceeding, or analogous process involving a patent application or patent included in the Patent Assets. Each Party thereafter shall cooperate fully with the other with respect to any such patent office proceeding. Each Party will provide the other with any information or assistance that is reasonable. 7.3. Enforcement and Defense. (a) Each Party shall promptly give the other Party notice of any infringement in the Territory of any patent application or patent included in the Patent Assets that * Confidential Treatment Requested Page 27 of 46 comes to such Party's attention. The Parties will thereafter consult and cooperate fully to determine a course of action, including, without limitation, the commencement of legal action by any Party. However, INTERNEURON shall have the first right to initiate and prosecute such legal action at its own expense and in the name of URIACH and INTERNEURON, or to control the defense of any declaratory judgment action relating to Patent Assets. INTERNEURON shall promptly inform URIACH if INTERNEURON elects not to exercise such first right, and URIACH thereafter shall have the right either to initiate and prosecute such action or to control the defense of such declaratory judgment action in the name of URIACH and, if necessary, INTERNEURON. In no event shall URIACH be obligated to enforce or defend any of the Patent Assets. (b) If INTERNEURON elects not to initiate and prosecute an infringement or defend a declaratory judgment action in any country in the Territory as provided in Subsection 7.3(a), and URIACH elects to do so, the cost of any agreed-upon course of action, including the costs of any legal action commenced or any declaratory judgment action defended, shall be borne solely by URIACH. (c) For any such legal action or defense, in the event that any Party is unable to initiate, prosecute, or defend such action solely in its own name, the other Party will join such action voluntarily and will execute all documents necessary for the Party to prosecute, defend and maintain such action. In connection with any such action, the Parties will cooperate fully and will provide each other with any information or assistance that either reasonably may request. (d) Any recovery obtained by INTERNEURON or URIACH shall be shared as follows: (i) the Party that initiated and prosecuted, or maintained the defense of, the action shall recoup all of its costs and expenses (including reasonable attorneys' fees) incurred in connection with the action, whether the recovery is by settlement or otherwise; (ii) the other Party then shall, to the extent possible, recover its costs and expenses (including reasonable attorneys' fees) incurred in connection with the action; (iii) if URIACH initiated and prosecuted, or maintained the defense of, the action, the amount of any recovery remaining then shall be retained by URIACH; and Page 28 of 46 (iv) if INTERNEURON initiated and prosecuted, or maintained the defense of, the action, the amount of any recovery remaining shall be retained by INTERNEURON, except that URIACH shall receive a portion equivalent to the royalties or other payments it would have received if such amount were deemed Net Sales. (e) URIACH shall inform INTERNEURON of any certification regarding any Patent Assets it has received pursuant to either 21 U.S.C. 355(b)(2)(A)(iv) or (j)(2)(A)(vii)(IV) or under Canada's Patented Medicines (Notice of Compliance) Regulations Article 5 and shall provide INTERNEURON with a copy of such certification within five (5) days of receipt. URIACH's and INTERNEURON's rights with respect to the initiation and prosecution, or defense, of any legal action as a result of such certification or any recovery obtained as a result of such legal action shall be allocated as defined in Subsections 7.3.(d) (i) through (iv); provided, however, that INTERNEURON shall exercise the first right to initiate and prosecute, or defend, any action and shall inform URIACH of such decision within fifteen (15) days of receipt of the certification, after which time, if INTERNEURON has not advised URIACH of its intention to initiate and prosecute, or defend, such action, URIACH shall have the right to initiate and prosecute, or defend, such action. 7.4. Infringement of Third Party's rights. (a) URIACH is not aware of any reason why any Third Party could claim that the performance of any of the operations contemplated in this Agreement, including but not limited to the development, manufacture, use and sale of Compound and Product would infringe any patent rights owned or possessed by any Third Party. The above notwithstanding URIACH does not give any warranty in respect of such matters, and both Parties agree that URIACH shall not be held liable in case that the performance of any of the operations contemplated in this Agreement is deemed to infringe any intellectual property rights of any Third Parties and that if any Third Party files any claim or takes any other action as a consequence of or derived from the performance of any of the operations contemplated in this Agreement, claiming that such operations infringe such Third Party's patent rights, whether against URIACH or against INTERNEURON, any of its Affiliates or Sublicensees, then INTERNEURON shall bear all costs and economic liabilities resulting from any such Third Party action and shall indemnify and hold URIACH harmless. (b) The Party receiving any claim in respect of which an obligation to indemnify and hold harmless exists under this clause shall promptly inform the other. The receiving Party shall be entitled to appoint counsel to defend its own case, but shall make sure that the other Party is given access to all the documentation related to the case and Page 29 of 46 that such other Party is able to participate also in defending the case. Either Party, as the case may be, shall render to the other any reasonable assistance requested to it in connection with the defense of such action. (c) INTERNEURON agrees that it shall use commercially reasonable efforts to contest any claim, interim decision, injunction, order, judgement, etc stating or ruling that its activities under this Agreement infringe Third Party patent rights. In the event that INTERNEURON wishes to waive its rights of appeal or settle any claim, INTERNEURON shall first consult with URIACH, shall allow URIACH to actively participate in any settlement negotiations but INTERNEURON shall not, without URIACH'S prior written consent, which consent shall not be unreasonably withheld or delayed, settle any such claim or proceeding 7.5. Patent Term Extensions and Supplemental Protection Certificates. The Parties shall cooperate in obtaining patent term extensions or supplemental protection certificates or their equivalents in any country in the Territory where applicable and where desired by INTERNEURON. If elections with respect to obtaining such extension or supplemental protection certificates are to be made, INTERNEURON shall have the right to make the election, provided that it shall need URIACH'S prior written consent if it does not intend to seek such extension or supplemental certificates. ARTICLE VIII TERM AND TERMINATION 8.1. Term and Expiration. This Agreement shall be effective as of the Effective Date and unless terminated earlier pursuant to Section 8.2 and 8.3 below, the term of this Agreement shall continue in effect until expiration of all royalty obligations hereunder. 8.2.

Notwithstanding anything contained herein to the contrary, INTERNEURON shall have the right to terminate this Agreement at any time by giving thirty (30) days advance written notice to URIACH. Such notice shall explain the reasons for INTERNEURON's decision. INTERNEURON shall also give URIACH the opportunity to discuss the matter and shall refrain from taking any specific action until such discussions have taken place in good faith. If after having heard URIACH's point of view, INTERNEURON still wants to go ahead with termination, it shall send an additional notice to URIACH in writing, and in this event (i) the rights and obligations hereunder, excluding any payment obligation that has accrued as of the termination date and excluding rights and obligations relating to confidentiality, shall terminate immediately, and (ii) the provisions of Section 8.4 shall be applicable. 8.3. Termination for Cause Page 30 of 46 (a) Either Party may terminate this Agreement by notice to the other Party at any time during the term of this Agreement if the other Party is in breach of any material obligation hereunder by causes and reasons within its control, or has breached, in any material respect, any representations or warranties set forth in Article VI, and has not cured such breach within ninety (90) days after notice requesting cure of the breach, provided, however, that if the breach is not capable of being cured within ninety (90) days of such written notice, the Agreement may not be terminated so long as the breaching Party commences and is taking commercially reasonable actions to cure such breach as promptly as practicable. (b) Either Party may terminate this Agreement by notice to the other Party at any time during the term of this Agreement upon the filing or institution of bankruptcy, liquidation or receivership proceedings, or upon an assignment of a substantial portion of the assets for the benefit of creditors by the other Party; provided, -------- however, in the case of any involuntary bankruptcy, reorganization, ------- liquidation, receivership or assignment proceeding such right to terminate shall only become effective if the Party consents to the involuntary proceeding or such proceeding is not dismissed within ninety (90) days after the filing thereof. (c) URIACH may terminate this Agreement by by giving thirty (30) days advance written notice to INTERNEURON at any time during the term of this Agreement if INTERNEURON challenges the validity of any of the Patent Assets or opposes any grant or registration of any Patent Assets or in any other manner cooperates with any person or entity taking any action of this nature. 8.4. Effect of Expiration or Termination. (a) Expiration or termination of this Agreement shall not relieve the Parties of any obligation accruing prior to such expiration or termination. In addition to any other provisions of this Agreement which by their terms continue after the expiration of this Agreement, the provisions of Article IV shall survive the expiration or termination of this Agreement and shall continue in effect during the term set forth in Section 4.1. In addition, any other provision required to interpret and enforce the Parties' rights and obligations under this Agreement shall also survive, but only to the extent required for the full observation and performance of this Agreement. Any expiration or early termination of this Agreement shall be without prejudice to the rights of any Party against the other accrued or accruing under this Agreement prior to termination, including but not limited to URIACH's right to the milestone payment set forth in Section 5.2.(f) if such milestone is achieved after the expiration of the term of this Agreement. Except as expressly set forth herein, the rights to terminate as set forth herein shall be in addition to all Page 31 of 46 other rights and remedies available under this Agreement, at law, or in equity, or otherwise. (b) In the event of termination by INTERNEURON pursuant to Section 8.2., and in the event of termination by URIACH pursuant to any of Sections 3.5, 7.1., 8.3.(b) and 8.3.(c) in accordance with the terms of such respective sections, without prejudice to and subject to compliance with the provisions of any applicable law, and if requested by URIACH, INTERNEURON shall take and shall cause its Affiliates and Sublicensees to take, as the case may be, using reasonable commercial due diligence, any action necessary to transfer any and all rights to any INTERNEURON Know-How, to any Regulatory Approval (in the Territory, if the Agreement is terminated in its entirety, or in the applicable country in the Territory if the Agreement is terminated with respect to that country) and to any trademarks referred to in Section 3.6 to URIACH or URIACH's designee, at no cost to URIACH or to such designee, it being the intention of the Parties to secure that in these cases URIACH is put in a position where URIACH may, if URIACH so wishes, take over all the rights on the Compound and the Product in the country(ies) subject to the termination and exploit them as URIACH may deem convenient. (c) In the event this Agreement is terminated by URIACH pursuant to Section 8.3. (a), the provisions of Section 8.4. (b) shall also apply, provided; however, that if INTERNEURON disagrees with such termination URIACH shall give INTERNEURON the opportunity to discuss the matter and shall refrain from taking any specific action until such discussions have taken place in good faith. If after having heard INTERNEURON'S point of view, URIACH still wants to go ahead with termination, it shall send an additional notice to INTERNEURON in writing and the matter will be subject to the dispute resolution provisions of Section 10.5 of this Agreement; provided, however that if it is finally determined that such termination by URIACH was justified, then the provisions of Section 8.4. (b) shall apply. ARTICLE IX INDEMNIFICATION 9.1 Indemnification by INTERNEURON. INTERNEURON shall indemnify, defend and ------------------------------ hold URIACH and its officers, directors, shareholders, agents and employees harmless against any and all claims, liability, damage, loss, cost or expense (including reasonable attorney's fees) (collectively, "Losses") arising or resulting from any Third Party claim made or suit ------ brought against URIACH or such persons to the extent any such Losses arise out of (i) any breach by INTERNEURON of any of its representations or warranties Page 32 of 46 in this Agreement; (ii) INTERNEURON's negligence or willful misconduct; or (iii) the development, manufacture, use, importation, promotion, marketing commercialization, distribution and sale of the Compound or Product by INTERNEURON, or its Affiliates, or its Sublicensees, provided, however, that INTERNEURON shall not be required to indemnify any indemnified party referred to in this paragraph to the extent it is determined that the Losses resulted from the negligence or willful misconduct of such indemnified party or if an indemnified party would be required to indemnify INTERNEURON under Section 9.2 below. 9.2 Indemnification by URIACH. URIACH shall indemnify, defend and hold ------------------------- INTERNEURON, and its sublicensees, and their officers, directors, shareholders, agents and employees harmless against any and all Losses arising or resulting from any Third Party claim made or suit brought against INTERNEURON, its sublicensees or such other persons to the extent any such Losses arise out of (i) any breach by URIACH of any of its representations or warranties in this Agreement, (ii) URIACH'S negligence or willful misconduct; (iii) any defect associated with the Compound and/or the Product which should have been detected by URIACH when carrying out the development activities performed by URIACH prior to the Effective Date; or (iv) URIACH's manufacturing of Compound and Product as set forth in this Agreement and any activity by URIACH, its Affiliates or its sublicensees as a result of the exercise of any of the URIACH Options, provided, however, that URIACH shall not be required to indemnify any indemnified party referred to in this paragraph to the extent it is determined that the Losses resulted from the negligence or willful misconduct of such indemnified party or if an indemnified party would be required to indemnify URIACH under Section 9.1 above.

Applicable Law and Dispute Resolution. This Agreement shall be governed by and construed in accordance with the UNIDROIT principles (1994) applicable to International Commercial Contracts to the extent applicable, it being understood and agreed that any agreement between INTERNEURON and any Sublicensee may be governed by and construed in accordance with any other laws. The Parties agree to attempt initially to solve all claims, disputes, or controversies arising under, out of, or in connection with this Agreement by conducting good faith negotiations. If the Parties are unable to settle the matter between themselves within forty-five (45) days, either Party may initiate mediation upon written notice to the other Party. If the Parties have not reached a settlement within forty-five (45) days of the initiation of the mediation, then either Party may initiate binding arbitration proceedings. Whenever a Party shall decide to institute arbitration proceedings, it shall give written notice to that effect to the other Party. The Party giving such notice shall refrain from instituting the arbitration proceedings for a period of sixty (60) days following such notice. During such period, the Parties shall continue to make good faith efforts to amicably resolve the dispute without arbitration. Any arbitration hereunder shall be conducted under the rules of the International Chamber of Commerce ("ICC"). Each such arbitration shall be conducted by a panel of three arbitrators: one arbitrator shall be appointed by each of INTERNEURON and URIACH and the third shall be appointed by the other two arbitrators. Any such arbitration shall be held in London, England. The arbitrators shall have the authority to grant specific performance. Judgment upon the award so rendered may be entered in any court having jurisdiction or application may be made to such court for judicial acceptance of any award and an order of enforcement, as the case may be. In no event shall a demand for arbitration be made after the date when institution of a legal or equitable proceeding based on such claim, dispute or other matter in question would be barred by the applicable statute of limitations. Each Party shall bear its own costs and expenses incurred in connection with any arbitration proceeding and the Parties shall equally share the cost of the arbitration levied by the ICC. 10.6.

Rogers William B. Boni Executive VP and CFO VP, Corp. Communications (781) 861-8444 (781) 402-3410 INTERNEURON ACQUIRES WORLDWIDE RIGHTS TO DERSALAZINE FOR TREATMENT OF INFLAMMATORY BOWEL DISEASE Compound Has Unique Mechanism of Action Combining the Activities of an Approved Anti-inflammatory Agent and a Novel Potent PAF and Cytokine Inhibitor LEXINGTON, MA, October 1, 2001 -- Interneuron Pharmaceuticals, Inc. (NASDAQ: IPIC) today announced that it has licensed exclusive worldwide rights to dersalazine, a compound in early clinical development to treat Inflammatory Bowel Disease (IBD), which includes ulcerative colitis and Crohn's disease, from J. Uriach & Cia., S.A. of Barcelona, Spain. In exchange for an up-front licensing payment, development milestones and royalty payments to Uriach, Interneuron gains worldwide marketing rights to dersalazine, except in Spain, where Uriach retains an option to co-market the product. Interneuron will be responsible for the future clinical development, regulatory activities and commercialization of dersalazine. Interneuron plans to complete the Phase I clinical program and initiate Phase II trials in ulcerative colitis by the second half of 2002. Future studies will also explore the utility of the drug in Crohn's disease. "Dersalazine is an important addition to Interneuron's pipeline," said Glenn L. Cooper, M.D., president and chief executive officer of Interneuron. "This compound possesses a unique mechanism of action that combines the known anti-inflammatory activity of 5-ASA (5-Aminosalicylic Acid) with potent PAF (platelet activating factor) antagonism and cytokine inhibition. Our new partner, Uriach, possesses significant expertise in the field of anti-inflammatory therapeutics, and dersalazine represents the culmination of years of internal research. Standard effective therapies for ulcerative colitis are based on the activity of 5-ASA. The addition of PAF antagonism and cytokine inhibition has the potential to yield a medicine with advantages over currently available agents. -more- Page 45 of 46 -2- "New treatment options that induce and maintain remissions, minimize side effects and improve quality of life are needed for these diseases, which are growing in prevalence particularly in the U.S. and Europe," said Dr. Cooper. "Strategically, the planned development program for dersalazine is consistent with Interneuron's objective to acquire compounds with significant pre-clinical or early clinical data and subsequently to pursue a clear clinical and regulatory pathway for these products," said Dr. Cooper. "In line with our R&D strategy, Uriach has been seeking a partner for the worldwide development of dersalazine," said Enrique Uriach, chief executive officer of J. Uriach & Cia. "This compound has the potential for helping in a significant way the numerous patients who are affected by IBD worldwide. The potential of the U.S. market, Interneuron's expertise and commitment to the project, and above all, the synergies between the objectives of both companies, have been the main factors for reaching an agreement with Interneuron. This collaboration is one more example of Uriach's goal of forging long-lasting partnerships with other companies in order to jointly develop potential drug candidates originated at Uriach's R&D center." Dersalazine is a new chemical entity that combines a well-known anti-inflammatory agent, 5-ASA, with a novel potent agent that acts as a PAF antagonist and an inhibitor of key interleukin cytokines to achieve a synergistic therapeutic effect when compared to the activities of each component separately. Chemical cleavage of dersalazine by colonic bacteria releases the two active compounds for the topical treatment of inflammation in the colon. The 5-ASA molecule contained in dersalazine has known antioxidant properties which may ameliorate the deleterious inflammatory effects ascribed to the overproduction of free radicals. The PAF antagonist component in dersalazine blocks the effects of platelet activating factor, a naturally occurring mediator with pro-inflammatory effects implicated in the pathogenesis of IBD. In addition, dersalazine is believed to inhibit multiple cytokine interleukins that may be involved in the pathogenesis of the disease. An agent with these multiple anti-inflammatory actions might be expected to have significant advantages over existing therapies. In various experimental models of acute and chronic colitis, dersalazine has ameliorated or prevented the inflammatory response, as measured by tissue damage and biochemical inflammatory markers. Dersalazine appears to act locally on the colon without the liability of unwanted systemic absorption. The safety of single oral doses of dersalazine has been Page 46 of 46 demonstrated in healthy volunteers, in whom the systemic absorption of the compound and its two active components was low. Ulcerative colitis is a chronic disease that primarily affects the colon and causes inflammation in the upper layers of the large intestine, while Crohn's disease usually occurs in the small intestine and causes inflammation deeper within the wall of the intestine. Up to one million patients in the U.S. and two million worldwide suffer from these diseases. Fifty percent of these are affected by ulcerative colitis and 50 percent by Crohn's disease. Uriach is a private Spanish pharmaceutical company, established in 1838, with a broad commercial presence in Spain and with a world class research and development center that focuses its efforts in the early stages of drug development. Uriach's R&D efforts are centered in the cardiovascular and inflammation areas. Interneuron Pharmaceuticals is engaged in the development and commercialization of a portfolio of products and product candidates for panic/anxiety disorders, overactive bladder, liver disease, prevention of HIV infection, stroke and other disorders.
