("Optionee"), a Delaware corporation, having its place of business at One Kendall Square, Building 700, Cambridge, MA 02139, and Cambridge NeuroScience, Inc. ("CNSI"), a Delaware corporation, having a principal place of business at One Kendall Square, Building 700, Cambridge, MA 02139. BACKGROUND Certain inventions, generally characterized as and disclosed in UC Case No. 96-223 (the "Invention"), are covered by Regents' Patent Rights (defined below) and were made in the course of research at The J. David Gladstone Institutes ("Gladstone"), a charitable trust with of fines located at Irvine and San Francisco, California, by Drs. Robert W. Mahley, Robert E. Pitas and Karl H. Weisgraber (collectively, the Inventors"). Gladstone and The Regents entered into an agreement dated June 8, 1977, that agreement being amended on March 27, 1984, and further amended on January 21, 1986 (as amended, the "Gladstone/Regents Agreement"), establishing among other items, that the Invention and Regents' Patent Rights shall be managed in accordance with The Regents' policies and procedures and, as a result, the patent applications included in Regents' Patent 3 4 Rights covering the Invention are or will be assigned to The Regents, as will any resulting issued patents, whether domestic or foreign. Gladstone is not a party to this Option Agreement but Gladstone is granted certain rights with regard to sponsored research under a separate Research Agreement and with regard to equity in Optionee under a separate Stockholders' Rights Agreement (defined below), both executed concurrently with this Option Agreement. Development of the Invention was sponsored in part by The National Institutes of Health (Grant No. NHLBI-HL41633) and as a consequence this Option Agreement, any License Agreement (defined below), and the Invention are subject to overriding obligations to the Federal Government (including a non-exclusive, irrevocable license to use the Invention by or on behalf of the Government throughout the world), under 35 U.S.C. 200-212 and applicable regulations. The Regents elected on August 22, 1996, to retain title and granted the aforementioned licenses to the U.S. Government. CNSI and Gladstone entered into a Secrecy Agreement relating to the Invention dated December 4, 1995. CNSI and The Regents entered into a Secrecy Agreement relating to the Invention with an effective date of March 1, 1996, and further identified as UC Control No., 97-20-1035. Optionee is a "small business firm" as defined in Section 2 of Public Law 85-536 (15 U.S.C. 632) and a Subsidiary (defined below) of CNSI formed for the purpose of commercializing the Invention and New Inventions (defined below), among other things. Optionee wishes to evaluate the Invention and New Inventions under this Option Agreement to determine its interest in obtaining an exclusive worldwide license in the Field of Use (defined below) under Regents' Patent Rights covering the Invention, and in connection therewith, to obtain an exclusive option for such a license. 4 5 Optionee and Gladstone will enter concurrently into the Research Agreement (defined below), and CNSI will guarantee the financial obligations of Optionee under this Option Agreement and the Research Agreement as provided herein. Optionee, CNSI, Gladstone and The Regents will also enter concurrently into the Stockholders' Rights Agreement (defined below), and CNSI will guarantee the performance of Optionee under same. Pursuant to the Gladstone/Regents Agreement, Gladstone is obligated to disclose to The Regents any and all New Inventions and to assign its rights to any patent applications covering any New Inventions to The Regents. Pursuant to the Research Agreement, The Regents has agreed to file patent applications covering any and all New Inventions within the Field of Use for which Optionee has agreed to pay the patent costs and wishes to obtain an exclusive option for an exclusive worldwide license in the Field of Use under Regents' Patent Rights covering any such New Inventions in the Field of Use. The Regents wishes to grant to Optionee these options so that the Invention and any New Inventions in the Field of Use may be developed to the fullest extent and the benefits therefrom enjoyed by the general public.

This obligation is a material part of this Option Agreement and any breach by Optionee of this obligation or any breach of the Stockholders' Rights Agreement will be a breach by Optionee of this Option Agreement. 6.4 Optionee shall provide to The Regents semi-annual progress reports covering the development and testing of Licensed Product. Such progress reports may include copies of reports received by Optionee from Gladstone as required of Gladstone as set forth in the Research Agreement. The progress reports are due to The Regents on June 30 and December 30 of each year, beginning December 30, 1997, and for the life of this Option Agreement. 6.5 The progress reports will include, but are not limited to, the following topics so that The Regents may determine the progress of the development and testing of Licensed Product: o summary of work completed o key scientific discoveries o summary of work in progress o current schedule of anticipated events or milestones o a summary of resources (dollar value) spent in the reporting period 7. PATENT PROSECUTION AND MAINTENANCE 7.1 Subject to Section 7.6, The Regents shall diligently prosecute and maintain the 17 18 United States and foreign patent applications and patents comprising Regents' Patent Rights using counsel reasonably acceptable to Optionee, except for Regents' Patent Rights consisting of New Inventions jointly owned with Optionee, which will be prosecuted by Optionee as provided in Sections 7.4 and 7.5 herein. The Regents shall promptly provide Optionee with copies of all relevant documentation so that Optionee may be apprised of the continuing prosecution. Optionee shall keep this documentation in confidence in accordance with the provisions of Article 11 (CONFIDENTIALITY). 7.2 The Regents will hold title to all patents and patent applications subject to this Option Agreement, except as provided for in the Research Agreement, and The Regents' counsel will take instructions only from The Regents but The Regents shall use reasonable efforts to amend any patent application to include claims requested by Optionee and required to protect Licensed Product or Licensed Method. Pursuant to Section 6.2 of the Research Agreement, The Regents agrees to assert rights to the Invention and New Inventions in the Field of Use as long as this Option Agreement is in effect. 7.3 Except as provided in the Research Agreement with respect to jointly owned New Inventions, The Regents shall, at the request of Optionee, file, prosecute and maintain patent applications and patents covered by Regents' Patent Rights in foreign countries if available. The Regents shall notify Optionee in writing at least three (3) months prior to any applicable deadline for any foreign filings, and Optionee shall notify The Regents in writing of those countries in which it wishes foreign filings to occur within forty-five (45) days of the receipt of such request. Failure by Optionee to so notify The Regents within the forty-five (45) day period shall be deemed to constitute an election by Optionee not to request The Regents to secure foreign patent rights in such countries on behalf of Optionee. The Regents has the right to file patent applications at its own expense in any country in which Optionee has elected not to secure foreign patent rights, and those patent applications and resulting patents, if any, shall not thereafter be included in the licenses granted under this Option Agreement. 18 19 Confidential material omitted and filed separately with the Securities and Exchange Commission. Asterisks denote such omissions. 7.4 Optionee shall control the preparation, filing, prosecution and maintenance of United States and foreign patent applications, with respect to New Inventions jointly owned by The Regents and Optionee. Such applications shall be prepared, filed, prosecuted and maintained using counsel reasonably acceptable to The Regents. The Regents and Gladstone shall cooperate fully with and provide assistance to Optionee (or if the parties agree to have The Regents exercise control, Optionee shall cooperate fully with and provide assistance to The Regents) in connection with the preparation, filing, prosecution and maintenance of such jointly owned patent applications, including, without limitation, execution of all documents and performance of all acts reasonably necessary to file and prosecute such patent applications and maintain, enforce and defend such patents. Optionee and The Regents shall each provide the other in a timely manner with copies of all jointly owned patent applications filed by either pursuant to this Section, as well as those documents involved in the prosecution thereof, so that the other shall have an opportunity to provide comment on any such applications and documents. Such jointly owned patent applications and documents shall be held in confidence in accordance with the Provisions of Article 11 (CONFIDENTIALITY). Optionee shall bear the expenses associated with the filing and prosecution of such jointly owned patent applications. 7.5 Neither party, with respect to a New Invention jointly owned by Optionee and The Regents, shall abandon such patent application and resulting patent without first providing the other party with thirty (30) days' prior written notice. 7.6 Optionee shall pay all past, present and future costs incurred by The Regents and Gladstone in preparing, filing, prosecuting and maintaining all United States and foreign patents and patent applications covered by Regents' Patent Rights. Patent costs incurred as of the Effective Date are approximately **********************************************. 19 20 The parties shall consult in good faith with each other regarding the desirability of pursuing or defending any interferences or oppositions. The costs of interferences and opposition, if approved by Optionee in writing, are prosecution expenses and will be paid by the Optionee. If such costs are not approved by Optionee, or Optionee chooses not to participate in such interference and opposition, then such decision not to participate will be deemed an election by Optionee not to pursue such action on behalf of Optionee. Those patent applications and resulting patents, if any involved in such interferences and opposition shall not thereafter be included in the licenses granted under this Option Agreement, effective on the date The Regents provided notice to Optionee of such interference and opposition, and The Regents will have no further obligation to Optionee with respect thereto. Optionee shall reimburse The Regents for all costs and charges within thirty (30) days following receipt of a proper itemized invoice from The Regents for same. If this Option Agreement is in effect two (2) months before the due date of PCT filings, or four (4) months before the due date of National Phase filings, then Optionee shall pay for the relevant PCT Chapter I, PCT Chapter II or National Phase filings in all designated countries, notwithstanding the provisions of Section 7.5 below. If Optionee decides not to proceed with such interference and opposition, The Regents shall decide in its sole discretion, whether or not to enter any interference proceedings or opposition. 7.7 Optionee may terminate its obligations with respect to any patent application or patent in any or all designated countries upon three (3) months' prior written notice to The Regents. The Regents will use its best efforts to curtail the associated patent costs after notice is received from the Optionee. The Regents may continue prosecution and/or maintenance of those applications or patents at its sole discretion and expense and Optionee will have no further right or licenses thereunder. 7.8 The Regents will promptly transmit to Optionee any disclosures of New Inventions as provided in the Research Agreement. Within ninety (90) days of receipt by 20 21 Optionee of a disclosure of a New Invention, Optionee shall inform The Regents in writing, whether or not it wishes to include The Regents' interest in any New Invention within the Field of Use within Regents' Patent Rights and pay patent costs therefor under this Article. If Optionee does not elect or elects not to include The Regents' interest in the New Invention within Regents' Patent Rights, Optionee and CNSI shall have no further rights thereto. If Optionee does elect to include The Regents interest in the New Invention within Regents' Patent Rights, The Regents, to the extent it is legally able to do so, shall include its interest in any patent application filed under this Section 7.8 in this Option Agreement. 7.9 Optionee has a continuing responsibility to keep The Regents informed of its large/small business entity status (as defined by the United States Patent and Trademark Office). 8. LIFE OF THE OPTION AGREEMENT 8.1 Unless otherwise terminated by operation of law or by acts of the parties in accordance with the terms of this Option Agreement, this Option Agreement is in effect from the Effective Date and shall remain in effect for the period specified in Section 3.1 hereof.

TERMINATION FOR CAUSE 9.1 If a party violates or fails to perform any material term of this Option Agreement, then the aggrieved party may give written notice of default ("Notice of Default") to such party. If such party fails to repair the default within forty-five (45) days of the date of notice, then the aggrieved party has the right to terminate this Option Agreement upon delivery of a second written notice so stating ("Notice of Termination"). 9.2 If a Notice of Termination is delivered by a party, this Option Agreement shall automatically terminate on the effective date of such notice. Termination will not relieve a party of its obligation to pay all amounts under this Option Agreement, the Research Agreement or the Stockholders' Rights Agreement as of the date of termination and will not impair any accrued rights of the party. 9.3 If this Option Agreement is terminated for cause, a party shall, upon request made by another party, promptly return to the requesting party all tangible personal property and confidential data (including copies, facsimiles, and any derivatives thereof), belonging to 22 23 the party and provided to the requesting party. 9.4 The Regents will also have the right and option to terminate this Option Agreement if the Research Agreement or the Stockholders' Rights Agreement is materially breached or terminated by Optionee or CNSI prior to the agreed upon expiration date of the Research Agreement or the Stockholders' Rights Agreement and there has been no breach thereof by The Regents or Gladstone.
