Each party understands, acknowledges and agrees that the collaboration is experimental and work under the DEVELOPMENT PLAN may not achieve the overall goals in any year or the overall goals of the DEVELOPMENT PLAN. Subject to the parties' due diligence obligations, neither party shall have liability with respect to any failure of the COLLABORATION to develop a LICENSED PRODUCT. 5.6 Developmental Funding. In order to assist LKS to conduct its obligations under the DEVELOPMENT PLAN, GNE shall provide LKS with a $15-million-dollar line of credit, payable in accordance with a loan agreement between the parties entered into contemporaneously with this Agreement (the "LOAN AGREEMENT"). The parties initially believe that * patients are required for SUCCESSFUL PHASE II CLINICAL TRIAL COMPLETION. Should the parties agree that more than * patients will be required, GNE and LKS will mutually agree upon any increase in the size of the available line of credit, if necessary, for the incremental cost above the $15 million dollar credit limit for such additional patients required to complete LKS portion of the DEVELOPMENT PLAN. 5.7 Manufacturing. LKS shall be responsible, at its expense, to make or have made all requirements of the initial LICENSED PRODUCT for pre-clinical studies and clinical studies through the first SUCCESSFUL PHASE II CLINICAL TRIAL COMPLETION. Thereafter, GNE shall be responsible for worldwide production of LICENSED PRODUCTS for all other clinical trials and commercial requirements. If GNE requests, LKS will provide GNE with the necessary cell lines and LKS TECHNOLOGY, free of charge, to manufacture LICENSED PRODUCT. In the event LKS is contracting manufacturing to a THIRD PARTY and in the event LKS determines - ------------------- *Confidential treatment requested; material has been omitted and filed separately with the Commission. to change its contract manufacturer, LKS shall discuss such change with the DEVELOPMENT COMMITTEE before it makes such change, and obtain approval, not to be unreasonably withheld. 5.8 Small Molecule Programs. The parties acknowledge that both GNE and LKS have independent small molecule alpha4/beta7 antagonist programs. The parties agree that these programs will be kept separate from this COLLABORATION and that the parties will not share with each other any aspect of development of their respective small molecule programs. 5.9 Term and termination of the DEVELOPMENT COMMITTEE. The DEVELOPMENT COMMITTEE will cease its activities upon receipt of REGULATORY APPROVAL to sell the initial LICENSED PRODUCT in the United States and the EU. However, the COLLABORATION will continue so long as GNE is developing additional LICENSED PRODUCTS or further indications for the initial LICENSED PRODUCT. 5.10 Results of the Development Collaboration. (a) All right, title and interest in and to any new or useful process, manufacture, compound or composition of matter, materials, information, data, inventions and know-how, patentable or unpatentable, or any improvement thereof, conceived or first reduced to practice, or demonstrated to have utility during the conduct of the COLLABORATION (the "RESULTS"), and any patent applications or patents based thereon, solely by employees or others acting on behalf of LKS shall be owned solely by LKS ("LKS RESULTS"), and solely by employees or others acting on behalf of GNE shall be owned solely by GNE ("GNE RESULTS") in each case following the rules of inventorship pursuant to U.S. Patent law. (b) The Parties recognize that as a result of the COLLABORATION between GNE and LKS a joint invention may be made ("JOINT RESULTS"). In that event, the parties shall jointly own patents, inventor's certificates and applications therefor covering such JOINT RESULTS ("JOINT PATENTS"). Both GNE and LKS agree that such joint inventions will be jointly owned and GNE and LKS hereby agree to obligate their respective employee and consultant inventors to assign joint inventions jointly to GNE and LKS. (c) To the extent that any LKS RESULTS or JOINT RESULTS are necessary to make, have made, use or sell LICENSED PRODUCTS, LKS' interest in such RESULTS shall be included in LKS PATENTS and LKS TECHNOLOGY licensed to GNE in the TERRITORY and the OPTION TERRITORY, if applicable. SECTION 6 - PATENTS. 6.1 All proposed publications or communications relating to the COLLABORATION and the RESULTS therefrom shall be reviewed and approved by the parties hereto prior to submission for publication. A party will, upon request by the other party, delay publication to enable patent rights to be perfected and CONFIDENTIAL INFORMATION of the other party to be deleted, but in no event shall such delay exceed sixty (60) days from the time the publication was submitted to the receiving party, unless there will be a material impairment of PATENT RIGHTS. 6.2 (a) LKS shall disclose promptly to GNE the complete texts of all LKS PATENTS in existence on the EFFECTIVE DATE, which claim the manufacture, use or sale of a LICENSED PRODUCT as well as all information received concerning the institution or possible institution of any interference, opposition, re-examination, reissue, revocation, nullification or any official proceeding involving any such LKS PATENT. LKS agrees to keep GNE promptly and fully informed of the course of patent prosecution or other proceedings of such LKS PATENTS including by providing GNE with copies of substantive communications, search reports and THIRD PARTY observations submitted to or received from patent offices. (b) All reasonable PATENT COSTS which LKS will incur in the TERRITORY after the EFFECTIVE DATE for LKS PATENTS in existence on the EFFECTIVE DATE shall be reimbursed one-half by GNE within forty-five (45) days of receipt of an invoice reasonably describing the services performed provided, however, that (i) GNE and LKS shall mutually agree as to which countries within the TERRITORY to file, prosecute and maintain LKS PATENTS, and (ii) GNE shall have an equal say over all material matters related to the filing, prosecution and maintenance of the LKS PATENTS. All reasonable PATENT COSTS that LKS incurs after the EFFECTIVE DATE for such LKS PATENTS in the OPTION TERRITORY shall be reimbursed one-half by GNE as provided herein until the date of REGULATORY APPROVAL in the OPTION TERRITORY. Thereafter such PATENT COSTS shall be charged to OTHER OPERATING INCOME EXPENSE only if the OPTION is timely exercised, otherwise such PATENT COSTS shall continue to be paid by LKS and reimbursed one-half by GNE. (c) GNE shall have the right to assume responsibility for prosecution of any LKS PATENT or any part of any such LKS PATENT which LKS intends to abandon or otherwise cause or allow to be forfeited provided that the claims of such LKS PATENT covers LICENSED PRODUCT or any aspect of the manufacture, use or sale of LICENSED PRODUCTS. (d) GNE shall have no liability for reimbursing LKS for PATENT COSTS incurred by LKS prior to the EFFECTIVE DATE nor for LKS PATENTS (except JOINT PATENTS) filed by LKS but not in existence on the EFFECTIVE DATE. (e) GNE shall have the right to cause LKS to file divisional applications under LKS PATENTS for which GNE is providing reimbursement and which relate to subject matter that GNE, at its discretion, believes is important or essential to the manufacture, use or sale of LICENSED PRODUCT, and to share equally with LKS the PATENT COSTS of prosecution and maintenance of that subject matter. Subject matter not deemed important to GNE may be returned to LKS and prosecution and maintenance costs will be borne solely by LKS for the returned subject matter. 6.3 (a) GNE shall have the first right for JOINT PATENTS and the sole right for GNE PATENTS, using in-house or outside legal counsel selected at GNE's sole discretion, to prepare, file, prosecute, maintain and obtain extensions of GNE PATENTS or JOINT PATENTS in countries of GNE's choice throughout the TERRITORY and in the OPTION TERRITORY, including the naming of LKS inventors where appropriate in the case of JOINT PATENTS. GNE shall bear the PATENT COSTS relating to such activities in the TERRITORY and in the OPTION TERRITORY. Such PATENT COSTS in the OPTION TERRITORY after REGULATORY APPROVAL in the United States shall be charged by GNE to OTHER OPERATING INCOME/EXPENSE if the OPTION is timely exercised. GNE shall use reasonable efforts to solicit LKS's advice and review of the nature and text of JOINT PATENTS and material prosecution matters related thereto in reasonably sufficient time prior to filing thereof, and GNE shall consider in good faith LKS's reasonable comments related thereto. (b) LKS shall have the first right, using in-house or outside legal counsel selected at LKS's sole discretion, to prepare, file prosecute, maintain and obtain extensions of LKS PATENTS filed after the EFFECTIVE DATE in the OPTION TERRITORY and in countries of LKS' choice in the TERRITORY. LKS shall take into account GNE's reasonable comments related to such actions. All reasonable PATENT COSTS related to preparing, filing, prosecuting, maintaining and extending such LKS PATENTS shall be paid by LKS and after REGULATORY APPROVAL in the United States, such PATENT COSTS which relate to the OPTION TERRITORY may be charged by LKS to OTHER OPERATING INCOME/EXPENSE if the OPTION is timely exercised, otherwise such PATENT COSTS shall continue to be paid by LKS. (c) If GNE, prior or subsequent to filing any JOINT PATENTS, elects not to file, prosecute or maintain JOINT PATENTS or any claims encompassed by such JOINT PATENTS, GNE shall give LKS notice thereof within a reasonable period prior to allowing such JOINT PATENTS or such claims encompassed by such JOINT PATENTS to lapse or become abandoned or unenforceable, and LKS shall thereafter have the right, at its sole expense, to prepare, file, prosecute and maintain JOINT PATENTS or such claims encompassed by such JOINT PATENTS concerning all such inventions and discoveries in countries of its choice throughout the world. If LKS, prior or subsequent to filing LKS PATENTS, elects not to file, prosecute or maintain such LKS PATENTS or any claims encompassed by such LKS PATENTS, LKS shall give GNE notice thereof within a reasonable period prior to allowing such LKS PATENTS or such claims encompassed by such LKS PATENTS to lapse or become abandoned or unenforceable, and GNE shall thereafter have the right, at its sole expense, to prepare, file prosecute and maintain such LKS PATENTS or certain claims encompassed by such LKS PATENTS concerning all such inventions and discoveries in countries of its choice throughout the world. Notwithstanding the foregoing, neither GNE for the JOINT PATENTS nor LKS for the LKS PATENTS may abandon any subject matter reasonably related to the manufacture, use or sale of a LICENSED PRODUCT, without the consent of the other party. (d) The party filing JOINT PATENTS shall do so in the name of and on behalf of both GNE and LKS. Each of LKS and GNE shall hold all information it presently knows or acquires under this Section 6 which is related to all such PATENT RIGHTS as confidential subject to the provisions of Section 4 of this Agreement. 6.4 (a) In the event that a party becomes aware of significant actual or threatened infringement of an LKS PATENT or JOINT PATENT, anywhere in the world, that party shall promptly notify the other party in writing. GNE shall have the first right but not the obligation to bring an infringement action or file any other appropriate action or claim directly related to infringement of an LKS PATENT or a JOINT PATENT, wherein such infringement relates to LICENSED PRODUCT, against any THIRD PARTY and to use LKS's name in connection therewith. The costs of patent enforcement and related recoveries associated with the OPTION TERRITORY incurred by GNE shall be included in OTHER OPERATING INCOME/EXPENSE, if the OPTION has been timely exercised. Such patent enforcement costs in the TERRITORY shall be borne by GNE. If GNE does not commence a particular infringement action hereunder within ninety (90) days after it received such written notice, LKS, after notifying GNE in writing, shall be entitled to bring such infringement action or any other appropriate action or claim at its own expense and to use GNE's name in connection therewith. The party conducting such action shall consider in good faith the other party's comments on the conduct of such action. Recovery from any settlement or judgment from such action in the TERRITORY shall go first to reimburse the expenses of the parties in the infringement action and the remainder shall be shared by the parties in proportion to their respective economic interests in the specific LICENSED PRODUCT in the country subject to dispute. In any event, LKS and GNE shall assist one another and reasonably cooperate in any such litigation at the other's request without expense to the requesting party. (b) GNE shall have the sole right but not the obligation to bring an infringement action or file any other appropriate action or claim directly related to infringement of a GNE PATENT, wherein such infringement relates to LICENSED PRODUCT, against any THIRD PARTY and to use LKS' name in connection therewith. The costs of patent enforcement shall be incurred by and any related recovery shall be paid to GNE. 6.5 If a THIRD PARTY asserts that a patent or other right owned by it is infringed by any LICENSED PRODUCT in the OPTION TERRITORY or TERRITORY, GNE will be solely responsible for deciding how and whether to defend against any such assertions; provided, however, that to the extent that any such infringement action is filed or threatened in the OPTION TERRITORY, GNE shall discuss its strategy with LKS and consider LKS' comments in good faith. The costs of any such action in the OPTION TERRITORY (including the costs of any judgment, award, decree or settlement) will be chargeable to OTHER OPERATING INCOME/EXPENSE, if the OPTION has been timely exercised. The costs of defending any such action in the TERRITORY (excluding the costs of any judgment, award, decree or settlement) will be paid by GNE. If GNE is required to make any payments to such THIRD PARTY as a result of such action, such payments shall be considered OTHER ROYALTIES as defined and described in Section 7.3. SECTION 7 - COMPENSATION. 7.1 (a) Upon the EFFECTIVE DATE, GNE shall make an equity investment in LKS pursuant to a Securities Purchase Agreement ("SPA") and a Registration Rights Agreement entered into by the parties contemporaneously with this Agreement. (b) Upon the EFFECTIVE DATE, LKS shall issue to GNE a warrant ("WARRANT") to purchase two-hundred and fifty thousand shares (250,000) of LKS common stock pursuant to the SPA and the WARRANT executed by the parties contemporaneously with this Agreement. 7.2 (a) GNE shall pay the following amounts upon the occurrence of the following milestone events, which may be achieved by GNE through a SUBLICENSEE or AFFILIATE. (i) Upon the first REGULATORY APPROVAL in the United States of the initial LICENSED PRODUCT, GNE shall make a one-time payment to LKS of *; (ii) upon first REGULATORY APPROVAL of the initial LICENSED PRODUCT in the United Kingdom, Germany or France, GNE shall make a one-time payment to LKS of *. (b) As soon as practical after the SUCCESSFUL PHASE II CLINICAL TRIAL COMPLETION, GNE shall deliver to LKS a projected budget of the PRE-APPROVAL DEVELOPMENT COSTS. (c) After receipt by LKS of the budget provided in Section 7.2(b) LKS shall have the option during the next ninety (90)-days to elect to pay twenty-five percent (25%) of all subsequent PRE-APPROVAL DEVELOPMENT COSTS (the ___________________ *Confidential treatment requested; material has been omitted and filed separately with the Commission. "OPTION"). If LKS timely exercises the OPTION and repays the loan in full, (1) LKS shall share in * of the OPERATING PROFIT OR LOSS relative to the LICENSED PRODUCT in the OPTION TERRITORY and (2) subject to Section 7.3, GNE shall pay LKS a royalty of * of ROYALTY-BEARING SALES of LICENSED PRODUCTS on the first * in annual ROYALTY-BEARING SALES in all countries of the TERRITORY (which shall exclude the United States) and * on greater than * annual ROYALTY-BEARING SALES in all countries of the TERRITORY (which shall exclude the United States). In addition, if the OPTION is timely exercised and Subject to Section 7.2(d), GNE will provide a loan to LKS of sufficient funds to cover its twenty-five percent (25%) of PRE-APPROVAL DEVELOPMENT COSTS on the terms set forth in the LOAN AGREEMENT. If the OPTION is not timely exercised and subject to Section 7.3, GNE shall pay LKS (i) a royalty of * of ROYALTY-BEARING SALES of LICENSED PRODUCTS on the first * in annual ROYALTY-BEARING SALES in the United States and * on annual ROYALTY-BEARING SALES in the United States greater than *; and (ii) a royalty of * of ROYALTY-BEARING SALES of LICENSED PRODUCTS on the first * in annual ROYALTY-BEARING SALES in all countries of the TERRITORY except the United States and * on greater than * annual ROYALTY-BEARING SALES in all countries of the TERRITORY except the United States. OPERATING PROFIT OR LOSS in the OPTION TERRITORY, if applicable, and royalties shall be payable on a country-by-country, LICENSED PRODUCT-by-LICENSED PRODUCT basis, for * from FIRST COMMERCIAL SALE in a country. - ------------------- *Confidential treatment requested; material has been omitted and filed separately with the Commission. (d) If a second PHASE III CLINICAL TRIAL is required for the first REGULATORY APPROVAL of a LICENSED PRODUCT, LKS may elect, within sixty (60) days following receipt from GNE of a revised budget for the revised PRE-APPROVAL DEVELOPMENT COSTS to continue to pay twenty-five percent (25%) of PRE-APPROVAL DEVELOPMENT COSTS, in which case, LKS shall continue to share in the OPERATING PROFIT OR LOSS for such LICENSED PRODUCT in the OPTION TERRITORY, if the loan is repaid in full. If LKS elects not to share in such costs, then LKS will be deemed to have elected not to share in such OPERATING PROFIT or LOSS and the royalty provisions in Section 7.2(c) shall be applicable thereto; provided, however, that in such instance LKS will repay all amounts previously loaned to LKS pursuant to the terms of the LOAN AGREEMENT. 7.3 In the event that royalties are required to be paid by GNE or its AFFILIATES or SUBLICENSEES in a particular country to a THIRD PARTY who is not an AFFILIATE of GNE in such country in order for GNE or its AFFILIATES or SUBLICENSEES in such country to make, have made, use, import, offer for sale, sell or have sold a LICENSED PRODUCT without infringing such THIRD PARTY'S patents in such country and for which royalties are also due to LKS on ROYALTY-BEARING SALES pursuant to this Agreement (such royalties to such THIRD PARTY are hereinafter "OTHER ROYALTIES"), then the royalties to be paid to LKS in such country by GNE hereunder shall be reduced by * of the amount of such - ------------------- *Confidential treatment requested; material has been omitted and filed separately with the Commission. OTHER ROYALTIES, but in no event shall any royalties payable to LKS under this Agreement be reduced by more than *. 7.4 GNE shall keep, and shall cause each of its AFFILIATES and SUBLICENSEES to keep, full and accurate books of account containing all particulars relevant to its sales of LICENSED PRODUCTS that may be necessary for the purpose of calculating all royalties and other compensation payable to LKS. Such books of account shall be kept at their principal place of business and, with all necessary supporting data shall, for the three (3) years next following the end of the calendar year to which each shall pertain, be open for inspection by an independent certified public accountant reasonably acceptable to GNE, upon reasonable notice during normal business hours at LKS's expense for the sole purpose of verifying royalty and other compensation statements or compliance with this Agreement. In the event the inspection determines that payments due LKS for any period have been underpaid by five percent (5%) or more, then GNE shall pay for all costs of the inspection. In all cases, GNE shall pay to LKS any underpaid royalties or other compensation promptly and with interest at the prime rate set forth in the Wall Street Journal, plus two percent (2%). In the event of an overpayment by GNE, LKS shall promptly refund that overpayment. All information and data reviewed in the inspection shall be used only for the purpose of verifying royalties and other - ------------------- *Confidential treatment requested; material has been omitted and filed separately with the Commission. compensation due hereunder and shall be treated as GNE Confidential Information subject to the obligations of this Agreement. No audit by an agent of LKS shall occur more frequently than once during any twelve (12) month period. 7.5 In each year the amount of royalty or other compensation due shall be calculated quarterly as of the end of each calendar quarter (each as being the last day of an "Accounting Period") and shall be paid quarterly within the sixty (60) days next following such date. Every such payment shall be supported by the accounting prescribed in Section 7.6 and shall be made in United States currency. 7.6 With each quarterly payment, GNE shall deliver to LKS a full and accurate accounting to include at least the following information: (a) ROYALTY BEARING SALES for each LICENSED PRODUCT (by country), including a calculation explaining the deductions to reach ROYALTY BEARING SALES; (b) Total royalties payable to LKS; and (c) A calculation of the conversion of local currency sales to U.S. Dollars; (d) OPERATING PROFIT OR LOSS analysis of compensation due LKS in the U.S., if applicable. Accordingly, within sixty (60) days following the end of each calendar quarter, GNE shall (i) provide LKS with a report calculating OPERATING PROFIT or LOSS for the quarter, and (ii) pay LKS its share of any OPERATING PROFIT or bill LKS for its share of any OPERATING LOSS. If there is an OPERATING LOSS, LKS will pay GNE for LKS' portion of the OPERATING LOSS within thirty (30) days of receiving the OPERATING LOSS report. 7.7 In each country where the local currency is blocked and cannot be removed from the country, at the election of LKS, royalties accrued in that country shall be paid to LKS in the country in local currency by deposit in a local bank designated by LKS or shall be paid to LKS on the ROYALTY BEARING SALES to the importer of the LICENSED PRODUCT in that country rather than on such sales in that country. 7.8 For the purpose of computing ROYALTY-BEARING SALES for LICENSED PRODUCTS sold in a currency other than United States Dollars, such currency shall be converted into United States Dollars in accordance with GNE's customary and usual translation procedures consistently applied. Such procedures shall, at LKS request, be provided to LKS 7.9 LKS shall pay any and all taxes levied on account of, or measured exclusively by, any payment including royalties it receives under this Agreement. If laws or regulations require that taxes be withheld, GNE will (i) deduct those taxes from the remittable amount, (ii) timely pay the taxes to the proper taxing authority, and (iii) send proof of payment to LKS within sixty (60) days following that payment and reasonably cooperate with LKS, at LKS's expense, in any proceeding with such taxing authorities. SECTION 8 - REPRESENTATIONS AND WARRANTIES. 8.1 Each party represents and warrants to the other party that: (i) it is free to enter into this Agreement; (ii) in so doing, it will not violate the terms of or cause a breach of any other agreement to which it is a party; and (iii) it has taken all corporate action necessary to authorize the execution and delivery of this Agreement and the performance of its obligations under this Agreement. 8.2 LKS hereby represents and warrants to GNE that: (a) It is the owner of, or is the licensee of the proprietary information related to LICENSED PRODUCTS which it has provided to GNE under this Agreement, and accordingly has the right to grant licenses or sublicenses therefor. (b) LKS has not, and during the term of this Agreement, will not, grant any right to any THIRD PARTY relating to the LICENSED PRODUCT in the FIELD which would conflict with the rights granted to GNE hereunder. (c) Except pursuant to the Other Party Agreements, LKS is not obligated under any agreement with a THIRD PARTY to pay such THIRD PARTY royalties regarding the LICENSED PRODUCT. 8.3 LKS agrees that during the term of the COLLABORATION, LKS will not develop, manufacture or sell a monoclonal antibody that competes with LICENSED PRODUCT. 8.4 EXCEPT AS OTHERWISE EXPRESSLY SET FORTH IN THIS AGREEMENT NEITHER PARTY MAKES ANY REPRESENTATIONS OR EXTENDS ANY WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT OR VALIDITY OF ANY LKS PATENT, GNE PATENT OR OTHER INTELLECTUAL PROPERTY RIGHTS. SECTION 9 - INDEMNIFICATION. 9.1 Indemnification by GNE in the TERRITORY (a) GNE will defend, indemnify and hold harmless LKS, its AFFILIATES and licensors and their employees, agents, officers, trustees, shareholders and directors and each of them (the "LKS Indemnified Parties") from and against any and all THIRD PARTY claims, causes of action and costs (including reasonable attorney's fees) of any nature made or lawsuits or other proceedings filed or otherwise instituted against the LKS Indemnified Parties resulting from or arising out of the DEVELOPMENT, manufacture, sale or use of any LICENSED PRODUCT performed by GNE, its AFFILIATES or its SUBLICENSEES in the TERRITORY (other than those claims which result from the negligence or willful misconduct of an LKS Indemnified Party). Indemnification by LKS in the TERRITORY (b) LKS will defend, indemnify and hold harmless GNE, its AFFILIATES and SUBLICENSEES and their employees, agents, officers, shareholders and directors and each of them (the "GNE Indemnified Parties") from and against any and all THIRD PARTY claims, causes of action and costs (including reasonable attorney's fees) of any nature made or lawsuits or other proceedings filed or otherwise instituted against the GNE Indemnified Parties resulting from or arising out of the DEVELOPMENT, testing, manufacturing or use of any LICENSED PRODUCT performed by LKS or its AFFILIATES in the TERRITORY (other than those claims which result from the negligence or willful misconduct of a GNE Indemnified Party). Conditions to Indemnification in the TERRITORY (c) A person or entity that intends to claim indemnification under this Section (the "Indemnitee") shall promptly notify the other party (the "Indemnitor") of any loss, claim, damage, liability or action in respect of which the Indemnitee intends to claim such indemnification, and the Indemnitor may assume direction and control of the defense thereof (including the right to settle solely for monetary consideration) with counsel chosen by the Indemnitor whether or not such claim is rightfully brought; provided, however, that an Indemnitee shall have the right to retain its own counsel, at its own expense. The Indemnitor may not settle any claims for other than monetary consideration without the consent of the Indemnitee, which consent will not be unreasonably withheld. The failure to deliver notice to the Indemnitor within a reasonable time after the commencement of any such action, only if prejudicial to its ability to defend such action, shall relieve such Indemnitor of any liability to the Indemnitee under this Section, but the omission so to deliver notice to the Indemnitor will not relieve it of any liability that it may have to any Indemnitee otherwise than under this Section. The Indemnitee under this Section, its employees and agents, shall cooperate fully with the Indemnitor and its legal representatives in the investigations and defense of any action, claim or liability covered by this indemnification at the cost of the Indemnitor. OPTION TERRITORY Indemnification 9.2 If applicable, each party hereby agrees to save, defend and hold the other party and its agents, officers, employees, directors, shareholders and AFFILIATES and SUBLICENSEES harmless from and against any and all THIRD PARTY claims, causes of action and costs (including reasonable attorneys fees) of any nature made or lawsuits or other proceedings filed or otherwise instituted against each party resulting from or arising out of the DEVELOPMENT, manufacture, use or sale of any LICENSED PRODUCT in the OPTION TERRITORY by the indemnifying party, its AFFILIATES, agents, or SUBLICENSEES, but only to the extent such losses result from the negligence or willful misconduct of the indemnifying party or its employees, agents, affiliates or SUBLICENSEES and do not also result from the negligence or willful misconduct of the party seeking indemnification. Any other losses (including reasonable attorneys fees) resulting from or arising out of the DEVELOPMENT, manufacture, use or sale of any LICENSED PRODUCT in the OPTION TERRITORY shall be charged to OTHER OPERATING INCOME/EXPENSE at the time such claim is finally determined, whether by judgment, award, decree or settlement. In the event that either party receives notice of a claim with respect to a LICENSED PRODUCT in the OPTION TERRITORY, such party shall inform the other party as soon as reasonably practicable. The parties shall confer as to how to respond to the claim and how to handle the claim in an efficient manner. SECTION 10 - ASSIGNMENT; SUCCESSORS. 10.1 This Agreement shall not be assignable by either of the parties without the prior written consent of the other party (which consent shall not be unreasonably withheld), except that either party, without the consent of the other, may assign this Agreement to a successor in interest or transferee of all or substantially all of the portion of the business to which this Agreement relates. 10.2 Subject to the limitations on assignment herein, this Agreement shall be binding upon and inure to the benefit of said successors in interest and assigns of the parties. Any such successor or assignee of a party's interest shall expressly assume in writing the performance of all the terms and conditions of this Agreement to be performed by said party and such assignment shall not relieve the assignor of any of its obligations under this Agreement. SECTION 11 - FORCE MAJEURE. Neither party shall be liable to the other party for damages or loss (other than with respect to payments due LKS hereunder) occasioned by failure of performance by the defaulting party if the failure is occasioned by earthquake, war, fire, explosion, flood, strike or lockout, embargo, or any similar cause beyond the control of the defaulting party, provided that the party claiming this exception has exerted all reasonable efforts to avoid or remedy such event and provided such event does not extend for more than six (6) months and provided in no event shall a party be required to settle any labor dispute or disturbance. In the event the force majeure event extends for more than six (6) months, and could have been cured by a party's best efforts, then the other party may terminate this Agreement upon written notice to the non-performing party so long as the other party is not then in material breach of this Agreement. SECTION 12 - TERMINATION. 12.1 Except as otherwise specifically provided herein and unless sooner terminated pursuant to Sections 12.2 or 12.3 of this Agreement, this Agreement and the licenses and rights granted hereunder shall remain in full force and effect until GNE's obligations to pay royalties and/or profit share hereunder expires. Upon expiration of GNE's obligations to pay royalties and/or profit share hereunder with respect to a specific country and specific LICENSED PRODUCT as to which GNE's license is then in effect, the license granted to GNE with respect to such country and such LICENSED PRODUCT pursuant to Section 2.1 shall be deemed to be fully paid and GNE shall thereafter have an exclusive, sublicensable, royalty-free right and license under the LKS Patents and the LKS Technology to make, have made, use, sell, offer to sell, have sold and import such LICENSED PRODUCT in such country. 12.2 Upon breach of any material provisions of this Agreement by either party to this Agreement, which is not cured within sixty (60) days after written notice to the breaching party by the other party, in addition to any other remedy it may have, the other party at its sole option may terminate this Agreement, provided that such other party is not itself then in material breach of this Agreement. The rights and obligations of the parties upon termination are described in Sections 12.4, 12.5, 12.6 and 12.7. 12.3 Either party to this Agreement may, upon giving notice of termination immediately terminate this Agreement upon receipt of notice that the other party has become insolvent or has suspended business in all material respects, or has consented to an involuntary petition purporting to be pursuant to any reorganization or insolvency law of any jurisdiction, or has made an assignment for the benefit of creditors or has applied for or consented to the appointment of a receiver or trustee for a substantial part of its property. 12.4 In the event of termination of this Agreement by LKS under Section 12.2 or 12.3 or by GNE under Section 12.6: (a) all licenses granted to GNE hereunder shall terminate. (b) GNE shall assign or permit reference (at its option) to all regulatory filings for LICENSED PRODUCTS as appropriate and shall grant to LKS, all to the extent legally available, a non-exclusive, sublicensable, worldwide, royalty-bearing, license within the FIELD to make, have made, use sell, have sold, offer for sale or import LDP-02 under (1)issued GNE patents and GNE TECHNOLOGY which were applied to the development of LDP-02 under the Collaboration, (2) the CABILLY PATENTS, (3) issued THIRD PARTY patents licensed by GNE after the EFFECTIVE DATE and under which GNE has the right to grant a license to LKS hereunder, and (4) GNE's interest in the JOINT PATENTS within the FIELD, provided, however, that (i) such license shall be on commercially reasonable terms; (ii) LKS shall pay all royalties and payments due under and shall comply with the terms of the CABILLY PATENTS and the THIRD PARTY patent licenses as pass-through payments due thereunder, (iii) no license shall be granted to any intellectual property developed under the small molecule program described in Section 5.8, and (iv) the license described above in this Section 12.4(b) shall only be for patents required to make, have made, use, sell, have sold, offer for sale or import LDP-02 in the FIELD. (c) So long as the license described in Section 12.4(b) has been granted and is in full force and effect, LKS shall not bring any legal action against GNE for any losses or damages associated with and GNE shall have no other liability to LKS regarding termination of this Agreement, except losses and damages described in Section 9 - Indemnification. 12.5 In the event of a termination of this Agreement by GNE under Section 12.2 or 12.3: (a) there shall be deemed an event of default under the LOAN AGREEMENT and all principal and interest outstanding under the LOAN AGREEMENT shall be immediately due and payable.
