B. Amarin wishes to evaluate these Rights and to obtain an exclusive option for a transfer and assignment of such Rights in the Territory in the Field, each as defined below, and Elan is willing to make such disclosure as may be relevant to Amarin for purposes of its evaluation, and to grant such option for a transfer and assignment of the Rights upon the terms and conditions hereinafter set forth. C. Elan and Amarin, should Amarin exercise its Option (as defined below), wish to enter into an Assignment Agreement for the Rights in the Territory in the Field; and in the meantime, to establish a steering committee for the management of the completion of development of Zelapar in the Territory. AGREEMENT NOW, THEREFORE, in consideration of the foregoing and the mutual covenants set forth below, the parties hereby agree as follows: 1. Rights Subject to Option; Information Provided to Amarin. 1.1 Rights Defined. For the purposes of this Agreement, "Rights" shall mean all of Elan's right, title and interest in any data, information, or know-how pertaining to, and any license or other rights in, the Product in the Territory, now owned or controlled or hereafter acquired by Elan. By way of illustration, the foregoing Rights shall include but not be limited to (i) all of Elan's rights under the License and Supply Agreement between Elan or its affiliates and RP Scherer and Company, as amended (the "Scherer Agreement"), as it pertains to the Territory, and (ii) all clinical, preclinical and other data, protocols, inventory, work in progress, regulatory rights or applications of any kind (such as a New Drug Application ("NDA") for the Product), contract rights, market research, patent rights, patent applications, trademark rights, trademark applications, and any know-how associated with the Product for use in the Territory. 1.2 Information. Elan shall provide Amarin with continuing access to and, as appropriate, copies or samples of materials it has within its possession or control which are the subject of the Rights, together with all additional information, data, patent or trademark disclosures and know-how relating thereto now known to or hereafter developed or obtained by Elan during the Option Period (as defined below) (the "Information"), all on the terms and subject to the conditions of this Agreement. 2. Evaluation by Amarin. 2.1 Right to Evaluate. During the Option Period, Amarin shall have the continuing right to review the Information as Amarin determines is necessary to evaluate its interest in exercising the Option. During the Option Period, Amarin shall use the Information solely for that purpose. Elan shall make the Information available at its expense at 800 Gateway Blvd, South San Francisco, California 94080. 2.2 Return of Information if Option not Exercised. If Amarin terminates (which can occur only as provided in Section 8.2 below) or fails to timely exercise the Option, Amarin shall return to Elan, within thirty (30) days following the termination of the Option Period, all Information of Elan and all copies thereof (or Amarin's written confirmation that it has destroyed all such copies), except for one complete set of Information which Amarin may retain and use solely for compliance purposes under the confidentiality requirements of this Agreement. 3. Option to License. 3.1 Grant of Option. (a) Elan hereby grants to Amarin the following exclusive option (the "Option"), during the Option Period, to obtain an exclusive transfer and assignment of the Rights, on the terms stated below and in Exhibit A attached hereto and incorporated by this reference, to use,promote, distribute and sell the Product in the Territory, for use in the field of human therapeutic treatment of any disease, condition or disorder (the "Field"). It is understood and agreed that Elan retains all rights in the Product outside the Territory which it now or hereafter may own or control. For the purposes of this Agreement, the Territory shall mean the United States. (b) This Option is exercisable by written notice to Elan received at any time during the Option Period. If Amarin timely exercises the Option, the parties promptly shall negotiate in good faith and execute a mutually acceptable definitive assignment agreement (the "Assignment Agreement") which shall incorporate the terms and conditions set forth in this Agreement and shall include other terms and conditions which are reasonable and customary in transactions of this nature. (c) If the parties are unable to agree upon the form of the Assignment Agreement within thirty days of the date of the exercise of the Option, the parties shall submit any outstanding issues to senior management of each party, who shall negotiate in good faith a resolution. If thirty days after such submission to senior management issues remain unresolved, either party may submit its proposed Assignment Agreement to an arbitrator in the San Francisco, California area, selected under the then-current Commercial Rules of the American Arbitration Association, who will select one of the two proposed agreements, in its entirety. The arbitrator's decision will be final, binding and enforceable in a court of competent jurisdiction in San Francisco, California, which shall have exclusive jurisdiction over the matter. (d) Among other things, the Assignment Agreement shall provide that Amarin shall assume and perform Elan's obligations under the Scherer Agreement as of the date of the transfer and assignment of the Rights; that in the event of a conflict between the Scherer Agreement and the Assignment Agreement, the Scherer Agreement shall control; and that the parties shall cooperate reasonably to enable the other to fulfill their respective remaining obligations under the Scherer Agreement in and outside the Territory. 3.2 Option Period. The "Option Period" shall mean the period commencing on the date of this Agreement and expiring at 5:00 p.m. Pacific time on the day which is the earlier of the following: (i) thirty (30) days from the date on which Amarin receives a copy of the written approval of a New Drug Application ("NDA") by the Food and Drug Administration ("FDA") for immediate marketing of Zelapar in the Territory or (ii) execution by both parties of the Assignment Agreement. 3.3 Option Fees.

"Commercially Reasonable Efforts" of a Party shall mean efforts consistent with the exercise of its prudent business judgment as applied to other clinical, regulatory and commercialization efforts for products of similar performance and potential as would be undertaken in the pharmaceutical industry, but not less than those efforts applied by that Party to other similar products of its own product line. 4.
