However, in the event that the parties' original joint application for registration is not accepted, neither party shall initiate filing of any other application for registration of exclusive license rights in Japan covering, in whole or in part, the rights specified in the original joint application, without the prior approval of the other party. (B) Any registration of exclusive license rights for Eisai obtained pursuant to subsection 7(A) above shall terminate automatically upon the termination or expiration of the Eisai/IGEN License Agreement in accordance with the terms of that Agreement, and shall thereafter be of no further force or effect. (C) Nothing in this Supplemental Agreement shall in any way limit IGEN's rights, or constitute a waiver by IGEN of its rights, to enforce its patent rights against any infringer, notwithstanding the enforcement by Eisai of its interest in the co-owned registered senyo jisshi ken rights. In no event shall the provisions of the senyo jisshi ken referred to in subsection (A) above be construed to expand the scope of Eisai's license rights, nor shall Eisai have any right to obtain any compulsory license under any IGEN patent rights that would expand on such license rights granted to Eisai. 9 (D) Eisai and IGEN and their respective Affiliates shall each cooperate as needed in all actions with regard to applications referred to in subsection (A) above, and with regard to the resulting registrations and enforcement of rights thereunder, and with regard to deregistration in the event of termination or expiration of the Eisai/IGEN License Agreement. 8. Enforcement of Patent Rights Against Third Parties Clarifications: (A) Eisai and its Affiliates shall have the first right to enforce the registered senyo jisshi ken to be filed and co-owned by Eisai and IGEN or Affiliate established in Japan pursuant to Articles 3.1 to 3.3 of the Eisai/IGEN License Agreement and Section 7(A) above, against any third party infringer, but only in cases where the infringer is (i) making, using or selling an instrument which contains a wash station including a vessel and means for separating an immunocomplex containing analyte and an ECL-labeled moiety (bound phase), from other assay and/or sample components (free phase), either integral with or associated with said instrument, prior to transfer of the bound phase to the flow cell; or (ii) making, using or selling a compound, composition, reagent or kit for performing clinical immunoassays that use antibodies wherein the antibody combining site is directly involved in the detection or quantification of an analyte, wherein an immunocomplex containing analyte and an ECL-labeled moiety (bound phase), is separated from other assay and/or sample components (free phase) in the wash station of the instrument prior to transfer of the washed bound phase to the flow cell of the instrument and wherein bound phase coupled to paramagnetic beads is transferred to said flow cell and magnetically collected at the electrode. Any such action brought by Eisai and/or any of its Affiliates shall be at Eisai's own expense. If Eisai does not pursue such an action within the period specified in Section 11.5 of the Eisai/IGEN License Agreement, IGEN shall be entitled to enforce its proprietary rights according to the terms and procedures set forth in such Section 11.5. (B) Eisai may request IGEN and/or its Affiliate established in Japan to participate at their own expense in any enforcement action brought by Eisai and/or any of its Affiliates pursuant to subsection (A) above. Whether or not requested to do so by Eisai, IGEN and/or its Affiliate established in Japan shall be entitled to join in any such action, at their own expense, as a party. IGEN and/or its Affiliate established in Japan shall also be entitled to monitor proceedings brought by Eisai and/or any of its Affiliates by appointment of an attorney who shall be kept fully informed by Eisai. Eisai shall consult with IGEN in connection with any proposed settlement or compromise of any enforcement action brought by Eisai, and shall enter into any settlement or compromise only with the prior written approval of IGEN. 10 (C) IGEN or its Affiliate established in Japan shall have the sole right to enforce the registered senyo jisshi ken, obtained pursuant to subsection (A) above, at its own expense, against any third party infringer whose activity does not meet the criteria set forth in subsection (A) above. (D) In the event that a third party manufactures, uses or sells a clinical diagnostic instrument or immunoassay in Japan, which instrument or immunoassay (i) includes a Wash Station or Wash Step, (ii) falls outside the scope of Eisai's right to enforce its registered senyo jisshi ken rights under Section 7, and (iii) is not an instrument or Immunoassay for doctors' offices or for portable or hand-held use, or an instrument or immunoassay marketed for use in non-clinical markets, IGEN shall take all reasonable steps to enforce its proprietary rights in Japan against such third party. Eisai and IGEN acknowledge, however, that the line of Elecsys instruments (Elecsys 1010 and Elecsys 2010) currently being marketed by Boehringer Mannheim GmbH and its affiliates would not, if manufactured, used, or sold in Japan, justify any action by Eisai based on its exclusive license rights registration. (E) If Eisai requests IGEN to initiate an enforcement action pursuant to subsection 8(D), but IGEN doubts the validity of the position regarding proprietary rights it would be required to take in such an action, IGEN shall consult Nagashima & Ono or such other law firm as the parties may mutually select (hereinafter ALaw Firm@). Law Firm shall be asked first to render a written opinion to IGEN on the question whether its proprietary rights are enforceable against the alleged infringer. IGEN shall provide a copy of that opinion to Eisai. In the event the opinion is favorable, Law Firm shall take all reasonable actions, as instructed by IGEN, against the alleged infringer. All expenses of consultation with Law Firm and of any patent infringement proceeding shall be borne by Eisai, except that IGEN shall bear the costs of consultation with the Law Firm if the opinion of the Law Firm is clearly favorable on the issue of enforceability. 9. Cooperation in Financing Supplemental Provision: If requested by IGEN at any time after execution of this Supplemental Agreement, Eisai shall use reasonable efforts to cooperate with efforts by IGEN to obtain financing in Japan based on the commercial relationship reflected in the Eisai/IGEN License Agreement and this Supplemental Agreement by, if requested, providing information concerning sales of the Instruments and Assays in Japan, copies of its business plans for future sales in Japan, and projections, all subject to customary confidentiality restrictions agreed to by the potential financing sources who are given access to such information; and, if requested, making available a suitable, knowledgeable Eisai representative to discuss with representatives of potential financing sources the business progress and prospects for products and services covered by the Eisai/IGEN License Agreement and this Supplemental Agreement. Eisai will also consider in good faith any other reasonable requests by IGEN for additional cooperation in connection with financing, but Eisai retains full discretion to decide whether to comply with any such requests for additional cooperation. 11 10. Public Statements Supplemental Provision: In order to protect the integrity and confidentiality of the commercial relationship between Eisai and IGEN as reflected in the Eisai/IGEN License Agreement and this Supplemental Agreement, each party and it officers, and employees, shall refrain from issuing any press release, making any statement to any third party, or otherwise disseminating any information or opinion that might reasonably be interpreted as critical of the other party or its performance pursuant to the agreements referred to above, except as required by law or as part of the dispute resolution process set forth in Section 7 of the Eisai/IGEN License Agreement. Each party shall also use all reasonable efforts to ensure that its agents and other external representatives comply with the terms of this Section 10. 11. Effectiveness (A) This Supplemental Agreement shall become effective on the date as of which authorized representatives of each of Eisai and IGEN shall have signed it below. (B) At such time as this Supplemental Agreement may become effective, Eisai and IGEN agree to be bound by the mutual promises and obligations herein.

In such case that Eisai discontinues the sale in Japan of any Assay, for which assay Igen has created a substantial market outside of Japan, Eisai shall, if permitted by law and regulation of Japan and of any jurisdiction in which Igen proposes to manufacture and/or sell such assay, elect to do one of the following, to be chosen at Eisai's sole discretion: i. Continue to sell to Igen on commercially reasonable terms. ii. Grant a license to Igen, on commercially reasonable terms, to manufacture and sell such assay in an ECL format. iii. Inform Igen that Eisai will not object to nor interfere with IGEN's manufacture and sale outside Japan of such assay in an ECL format. Article 4. Payment Full payment of the amount due for all orders of product shall be due and payable by Igen to Eisai thirty (30) days after acceptance by Igen without discount or setoff for any reason. Payment shall be made by wire transfer in immediately available funds. 2 Article 5. Inspection Eisai shall give Igen reasonable opportunity to inspect Instruments and Assays prior to delivery and shall provide space for such inspection on Eisai's premises or on the premises of such subcontractor where final assembly of instruments may be done from time to time. Igen shall inspect or have inspected any Instrument and Assays prior to taking delivery. Inspection by Igen and approval of delivery shall constitute final acceptance by Igen. Non-conformance with Eisai published specifications shall be the only valid reason for rejection of any Instruments and Assays. In the case of any hidden defect in materials or workmanship, repair or replacement shall be made under Article 12 of this agreement. In the case that Igen rejects any Instruments and Assays, Igen shall set forth in writing the specific reason for such rejection including the specification which is not in conformance. If there is a disagreement as to the conformance with any specification, the parties shall ask for a judgment by an independent third party. In such case that Eisai agrees that there is non-conformance with a specification, or in the case that the third party has judged that there is non-conformance with a specification, Eisai shall repair or replace the Instrument or Assay at Eisai's sole discretion. Delay in delivery due to the determination by the third party of a non-conformance and/or Eisai's reasonably prompt repair or replacement of a non-conforming Instrument or Assay shall not be a breach of this Supplemental Agreement or of any purchase order. Reasonable promptness shall be determined with reference to the necessity of purchasing or manufacturing any parts or reagents necessary for replacement or repair. Article 6. Title and Risk The title and risk of loss or damage to the Instruments and Assays shall be transferred from Eisai to Igen when the Instruments and Assays are delivered to a common carrier at Eisai's loading dock or at such other site as may be mutually agreed, from time to time, between Eisai and Igen. Article 7. Re-export A. Igen warrants that all Instruments and Assays purchased by Igen from Eisai shall be shipped out of Japan. Igen shall not resell any Instruments or Assays in Japan, shall use reasonable efforts to assure that Instruments and Assays transferred to third parties by Igen are not re-imported to or resold in Japan, and shall not knowingly sell to any party who intends to re-import Instruments or Assays to Japan or who intends to sell to any party who would do so. B. Igen warrants that Igen shall not resell any Assays for use in any format other than ECL. The requirements for the previous sentences shall be fulfilled so long as all Assays sold by Igen are sold in ECL format and Igen ascertains that the end user of such assays possesses at least one ECL instrument. Igen shall use reasonable efforts to assure that 3 Assays transferred to third parties by Igen are not sold or resold for use in these formats other than ECL, and shall not knowingly sell to any party who intends to sell to a third party who would do so. Article 8. Reports Igen shall make quarterly reports to Eisai on the sales of Instruments and Assays including selling price, and shall also comment on the general market conditions. Eisai agrees to keep information divulged in each report confidential for a period of two years from the date of such report, except where such information is required to be disclosed by a government entity or pursuant to legal, administrative or regulatory proceedings. In any case of such requirement to disclose, Eisai shall inform Igen as soon as practicable so that Igen may take steps to prevent or limit such disclosure. Article 9. Indemnification Igen agrees to indemnify, hold harmless and defend Eisai, its Affiliates and their officers, employees and agents against any claims, suits, losses, damages, costs, fees, and expenses of every kind or nature whatsoever resulting from or arising out of the resale by Igen of any Instrument or Assay purchased hereunder, including without limitation: (a) Product liability claims. (b) Third party claims involving the manufacture, packaging, use, sale or other distribution of the Instruments or Assays. (c) Any representations made or warranty given by Igen or its Affiliates with respect to the Instruments or Assays. (d) Any claim for damages regarding the re-sale of Assays which have been sold to Igen in territories which Eisai has notified Igen that Eisai does not have the right to sell such assays. (e) Claims by IGEN's agents or distributors. (f) Claims arising from the acts or non-actions of IGEN's agents and distributors. Igen shall, at its own expense, take out and maintain sufficient insurance against product liability claims, and in particular shall include Eisai as a named insured on such policies. Igen shall provide Eisai with a copy of such insurance policies and evidence that the policies are in force, and shall provide new evidence that such policies have been renewed at least 30 days before the expiration of any such policy. 4 Article 10. Form and Packaging A. Instruments supplied under this Supplemental Agreement shall be supplied to Igen in the same form and packaging as Eisai supplies Instruments in Japan, except that they shall be supplied without the Eisai brand name affixed. B. Assays supplied under this Agreement shall be supplied in semi-finished package. Semi-finished shall mean that containers of each reagent of an assay kit, such reagents to be of the same size and concentration as sold in Japan, shall be boxed in multiple, labeled only on the box. Instruments pamphlets shall not be included. Article 11. Delivery Place Delivery shall be ex-factory Eisai's factory at Chiba, Japan. Eisai shall arrange for loading on a common carrier on IGEN's reasonable instructions. Article 12. Warranty Limited The only warranties provided under this Agreement shall be that a) Eisai shall repair or replace Instruments or Assays at Eisai's sole discretion, which Instruments or Assays are not conforming to the specifications of such Instruments or Assays and which nonconformance is noted and set out under Article 5 hereabove, and b) Eisai shall repair or replace at Eisai's sole discretion components of Instruments which are defective in materials or workmanship and which are returned to Eisai for Eisai for Eisai's verification of such defect. There are no other warranties either expressed or implied including any warranties of merchantability or fitness for any purpose, or of quality or safety of any parts, construction or design. Article 13. Training Eisai shall train, at cost, reasonable numbers of Igen personnel to enable them to adequately service Instruments. All such training shall take place in Japan at Eisai's specified location. Igen shall be responsible for all salaries, costs and expenses of its own personnel. With regard to personnel first sent to receive such training, Igen shall inform Eisai of IGEN's desire to send personnel for training 180 days prior to the proposed training and Eisai and Igen shall endeavor to agree on a suitable schedule for such training. With regard to subsequent personnel, Igen shall inform Eisai of IGEN's desire to send personnel for training 90 days prior to the proposed training and Eisai and Igen shall endeavor to agree on a suitable schedule for such training. 5 The information marked below with * and [ ] has been omitted pursuant to a request for confidential treatment.
