For the purposes of this Section 11.6, “commercially manufacture” shall mean the manufacture of supplies of the Collaboration Product for Phase I Clinical Studies, Phase II Clinical Studies and Phase III Clinical Studies as well as the manufacture of commercial supplies of the Collaboration Product for sale in the Territory. Furthermore, NVS agrees to retain control of the Research Materials and to transfer the Research Materials to any Third Party only for the purposes of manufacturing Collaboration Product for NVS. NVS shall inform HGS upon any transfer of the Research Materials to a Third Party, which notification may be provided through the JDC, JCC or JEC. If NVS breaches this provision relating to the transfer of the Research Materials to a Third Party and such breach is considered a breach of the AB License by HGS, HGS shall have the option to terminate this Agreement forthwith, notwithstanding the notice provision in Section 15.3.

ARTICLE 12

PATENTS

12.1 Subject to the license grants in Article 2 herein, HGS owns or controls the Albumin Fusion Know-How, Albumin Fusion Patent Rights, Albuferon Patent Rights and Manufacturing Technology and all HGS Arising Patent Rights and HGS Arising Know-How and NVS owns or controls the NVS Arising Patent Rights and NVS Arising Know-How. Joint Arising Know-How and Joint Arising Patent Rights shall be jointly owned by HGS and NVS. Subject to the licenses and other provisions of this Agreement, each Party may use and sublicense the Joint Arising Know-how and Joint Arising Patent Rights as it determines, without any required approvals from or accounting to the other Party.

12.2 NVS will prepare, file, prosecute and maintain Joint Arising Patent Rights and NVS Arising Patent Rights. In the event that NVS intends to abandon or decline responsibility for any or all of Joint or NVS Arising Patent Rights, NVS shall provide reasonable prior written notice to HGS of such intention to abandon or decline responsibility, and HGS shall have the right, at its own expense, to file, prosecute and maintain such Joint or NVS Arising Patent Rights.

12.3 HGS Responsibilities.

(a) Albumin Fusion Patent Rights, Albuferon Patent Rights and HGS Arising Patent Rights. HGS, or the Party who bears such responsibility under the AB License, will prepare, file, prosecute and maintain all Albumin Fusion Patent Rights, Albuferon Patent Rights and HGS Arising Patent Rights. HGS shall, in a timely fashion, provide NVS with copies of all written correspondence with the United States Patent and Trademark Office and all substantive communications from foreign patent offices pertaining to the filing, prosecution and maintenance of the Albumin Fusion Patent Rights (to the extent related to Collaboration Product), the Albuferon Patent Rights and the HGS Arising Patent Rights, and shall provide NVS with a timely and adequate opportunity to review and provide written comments on such matters which shall be reasonably taken into account by HGS or the outside counsel prosecuting such patent rights. HGS shall keep NVS advised on a quarterly basis, through the JEC, on the status of pending patent applications, including the grant of any Albumin Fusion Patent Rights (to the extent related to Collaboration Product), Albuferon Patent Rights and HGS Arising Patent Rights. NVS may identify in writing to HGS certain countries in which NVS desires that HGS, or the party who bears such responsibility under the AB License,

file, prosecute and maintain certain Albumin Fusion Patent Rights (to the extent related to Collaboration Product), Albuferon Patent Rights and/or HGS Arising Patent Rights. In the case of the Albumin Fusion Patent Rights (to the extent related to Collaboration Product), Albuferon Patent Rights and/or HGS Arising Patent Rights, including those HGS Arising Patent Rights for which HGS bears responsibility under the AB License, HGS shall thereafter file, prosecute and maintain such Albumin Fusion Patent Rights (to the extent related to Collaboration Product), Albuferon Patent Rights and/or HGS Arising Patent Rights in such country or countries. If HGS decides not to file, prosecute or maintain the Albumin Fusion Patent Rights (to the extent related to Collaboration Product), Albuferon Patent Rights or the HGS Arising Patent Rights in such countries identified by NVS and provided that HGS has the right to grant such right to NVS, HGS shall notify NVS of such decision in a timely fashion, and upon NVS request, HGS, in collaboration with NVS and using outside counsel mutually acceptable to HGS and NVS, shall file, prosecute and maintain such Albumin Fusion Patent Rights (to the extent related to Collaboration Product), Albuferon Patent Rights and/or HGS Arising Patent Rights in those countries and such Patent Rights will not be considered in determining whether any royalty is payable by NVS to HGS (or for determining the Royalty Term) under this Agreement; NVS shall responsible for all external costs and expenses relating to the preparation, filing, prosecution and maintenance of such Patent Rights. HGS shall at all times during its filing, prosecution, and maintenance of the Albumin Fusion Patent Rights (to the extent related to Collaboration Product), Albuferon Patent Rights and HGS Arising Patent Rights, use Commercially Reasonable Efforts to protect the commercial value of and maintain the Albumin Fusion Patent Rights, Albuferon Patent Rights and the HGS Arising Patent Rights.

(b) Manufacturing Technology. HGS shall have the right, but not the obligation, to file, prosecute and maintain all patent rights owned or controlled by HGS which claim the Manufacturing Technology; provided however, HGS only has the right if AB does not have the right and responsibility under the AB License. To the extent HGS has the right to file, prosecute and maintain those Patent Rights owned or controlled by HGS which claim the Manufacturing Technology, and to the extent such Patent Rights are directly related to the manufacture of Albuferon, NVS may identify in writing to HGS certain countries in which NVS desires that HGS file, prosecute and maintain such patent rights. HGS shall thereafter file, prosecute and maintain such patent rights which claim the Manufacturing Technology in such country or countries. If HGS does not file, prosecute and maintain such patent rights in such countries identified by NVS and provided that HGS has the right to grant such right to NVS, NVS shall have the right to file, prosecute and maintain such patent rights in those countries.

(c) All information, papers, and other materials provided by either Party to the other in accordance with this Section 12 shall be subject to the confidentiality provisions of this Agreement. The Parties shall share equally all external costs and expenses relating to the preparation, filing, prosecution and maintenance of the Albuferon Patent Rights relating to Collaboration Products. Otherwise, the Party controlling the preparation, filing, prosecution and maintenance of the Patent Rights shall be responsible for all costs related thereto. If outside counsel costs are incurred in connection with the preparation, filing, prosecution and maintenance of Albumin Fusion Patent Rights, Albuferon Patent Rights and HGS Arising Patent Rights, such outside counsel shall be mutually acceptable to both HGS and NVS. The Parties hereby agree that Finnegan Henderson Farabow

Garrett & Dunner LLP is acceptable as outside counsel for the purposes of this Section 12.3.

12.4 Enforcement.

(a) In the event that either NVS or HGS becomes aware of any infringement of any issued patent with the Patent Rights (except with respect to the Genentech Patent Rights) which infringement involves the HGS Collaboration Technology and/or Manufacturing Technology to which NVS has an exclusive license, it will notify the other Party in writing to that effect. Any such notice shall include evidence to support an allegation of infringement by such Third Party.

(b) Under the AB License, AB (or its assignee) has the first right (but not the obligation) to bring suit to abate any infringement or misappropriation of the Albumin Fusion Patent Rights, Albuferon Patent Rights and HGS Arising Patent Rights (to the extent such are jointly owned by HGS and AB). NVS will reasonably cooperate with AB in preparing and presenting any such suit or action.

(c) If AB declines to initiate a suit to abate any infringement or misappropriation, then HGS shall have the first right (but not the obligation), using counsel of its choice, to bring suit to abate any infringement or misappropriation of the Albumin Fusion Patent Rights, Albuferon Patent Rights and HGS Arising Patent Rights. HGS shall also have the first right (but not the obligation), using counsel of its choice, to bring suit to abate any infringement or misappropriation of the Manufacturing Technology. NVS will reasonably cooperate with HGS in preparing and presenting any such suit or action. In the United States, both Parties will equally share the costs and expenses of such suit and any recovery or damages derived from such an action or suit

shall be deemed Net Profit. In the Territory outside of the United States, the Party bringing the claim shall bear responsibility for all costs and expenses and any recovery or damages derived from such an action or suit (after the parties are reimbursed for their costs and expenses) shall be paid to NVS and considered Net Sales for purposes of calculating the royalties due under this Agreement.

(d) If HGS does not initiate a suit to abate any infringement or misappropriation in accordance with Section 12.4(c) within ninety (90) days of acquiring the right to do so in the applicable country or countries, then NVS may do so. HGS shall reasonably cooperate with NVS in preparing and presenting such action or suit. In the United States, both Parties will equally share the costs and expenses of such suit and any recovery or damages derived from such an action or suit shall be deemed Net Profit. In the Territory outside of the United States, the Party bringing the claim shall bear responsibility for all costs and expenses and any recovery or damages derived from such an action or suit (after the parties are reimbursed for their costs and expenses) shall be paid to NVS and considered Net Sales for purposes of calculating the royalties due under this Agreement.

(e) NVS shall have the right (but not the obligation) to bring suit to abate any infringement or misappropriation of the Joint Arising Patent Rights. HGS will reasonably cooperate with NVS in preparing and presenting any such action or suit. In the United States, both parties will equally share the costs and expenses of such suit and any recovery or damages derived from such an action or suit shall be deemed Net Profit. In the Territory outside of the United States, NVS shall bear responsibility for all costs and expenses and any recovery or damages derived from such an action or suit relating to

the Joint Arising Patent Rights (after the parties are reimbursed for their costs and expenses) shall be considered Net Sales for purposes of calculating the royalties due under this Agreement.

(f) If NVS does not initiate a suit to abate any infringement within ninety (90) days after receiving notice thereof, HGS shall have the right, but not the obligation, using counsel of its choice, to bring suit to abate any infringement or misappropriation of the Joint Arising Patent Rights. NVS will reasonably cooperate with HGS in preparing and presenting any such suit or action. In the United States, both parties will equally share the costs and expenses of such suit and any recovery or damages derived from such an action or suit shall be deemed Net Profit. In the Territory outside of the United States, the Party bringing the suit shall bear responsibility for all costs and expenses and any recovery or damages derived from such an action or suit (after the parties are reimbursed for their costs and expenses) shall be paid to NVS and considered Net Sales for purposes of calculating the royalties due under this Agreement.

(g) Neither Party may enter into any settlement without the prior consent of the other Party, which shall not be unreasonably withheld, and may not make any statement, which admits that any of the HGS Patent Rights is invalid or unenforceable.

12.5 Defense. In the event of the institution of any suit, opposition, or interference by a Third Party against HGS or NVS related to the HGS Patent Rights, the Party being sued shall promptly notify the other Party in writing. The Party being sued may, in its absolute discretion (subject to consent in certain circumstances described below), choose to defend, settle, and/or respond to, such suit at its own expense. Furthermore, if both Parties are sued, each may, in its absolute discretion(subject to consent in certain

circumstances described below), choose to defend, settle, and/or respond to, such suit at its own expense. HGS and NVS shall provide reasonable assistance to one another and reasonably cooperate in any such litigation at the other’s request at the expense of the requesting Party, provided, however, that neither Party may enter into any settlement without the prior consent of the other Party if such settlement would affect the other Party’s interests in and to the relevant Patent Rights or would impose any financial or other obligation on the other Party. Such consent shall not be unreasonably withheld.

12.6 For the intellectual property rights licensed in the Genentech Patents Rights, the Parties acknowledge that the Third Party licensors may control the right to bring suit and as a result, HGS’ and NVS’ rights may be limited, and the Third Parties may have the sole right to control such action.

12.7 Drug Price Competition and Patent Term Restoration Act. The Parties agree to cooperate in an effort to avoid loss of any Patent Rights which may otherwise be available to the Parties hereto under the provisions of the Drug Price Competition and Patent Term Restoration Act of 1984 or comparable laws outside the US, including by executing any documents as may be reasonably required. In particular, the Parties shall cooperate with each other in obtaining patent term restoration or supplemental protection certificates or their equivalents in any country and region where applicable to Collaboration Products. HGS shall provide all reasonable assistance to NVS, including permitting NVS to proceed with applications for such in the name of HGS, if so required. The Parties shall cooperate in determining, if applicable, which of the Patent Rights the Parties will attempt to extend, which determination shall be made by the JEC. HGS shall provide reasonable assistance to NVS, including by executing any required documents

and providing any relevant patent information to NVS, so that NVS, as Regulatory Filing applicant, may inform the relevant Regulatory Authority.

13.1 During the longer of the Term of this Agreement and [***] years from the date of disclosure (except with respect to the Confidential Information included in the Research Materials, for which the obligations will last for as long as such Confidential Information remains proprietary), each Party shall maintain in confidence the Confidential Information of the other Party, and shall not disclose, use or grant the use of the Confidential Information of the other Party except on a need-to-know basis to such Party’s Affiliates, directors, officers and employees, such Party’s Third Party licensors of intellectual property rights (sub)licensed hereunder, and such Party’s subcontractors, professional consultants and collaborators, to the extent such disclosure is reasonably necessary in connection with such Party’s activities as expressly authorized by this Agreement. To the extent that disclosure to any person is authorized by this Agreement, prior to disclosure, the Party shall ensure that such person is bound by confidentiality obligations with respect to Confidential Information at least as stringent as this Agreement. Each Party shall notify the other Party promptly upon discovery of any unauthorized use or disclosure of the other Party’s Confidential Information.

13.2 Notwithstanding the foregoing, the confidentiality obligations of Section 13.1 shall not include any information that: (a) is or hereafter becomes part of the public domain by public use, publication, general knowledge or the like through no wrongful act, fault or negligence on the part of receiving Party; (b) can be demonstrated by

documentation or other competent proof to have been in the receiving Party’s possession prior to disclosure by the disclosing Party; (c) is subsequently received by the receiving Party from a Third Party who is not bound by any obligation of confidentiality with respect to said information; (d) is generally made available to Third Parties by disclosing Party without restriction on disclosure; or (e) is independently developed by or for the receiving Party without reference to the disclosing Party’s Confidential Information.

13.3 The confidentiality obligations under Section 13.1 shall not apply to the extent that a Party is required to disclose information by applicable law, regulation or order of a governmental agency or a court of competent jurisdiction, including disclosures required under rules promulgated by the United States Securities and Exchange Commission; provided, however, that to the extent practicable, such Party (a) shall provide advance written notice thereof to the other Party and consult with the other Party prior to such disclosure with respect thereto, and (b) shall provide the other Party with reasonable assistance, as requested by the other Party, to object to any such disclosure or to request confidential treatment thereof, and (c) shall take reasonable action to avoid and/or minimize the extent of such disclosure.

(c) In the case of any termination by NVS under this Clause 15.2, NVS and HGS will agree to a wind-down plan covering the orderly transition or termination of

activities under the Development Plan and/or Marketing Plan during the relevant termination notice period (“Wind-Down Period”). NVS will be responsible for its share of the Development and Marketing Expenses actually incurred in connection with the plan and non-cancelable obligations incurred during the Wind-Down Period. The Parties agree that neither Party will initiate any new projects or activities during the Wind-Down Period for which it will seek funding or reimbursement from the other Party, that the total costs for the activities undertaken during the Wind-Down Period will not exceed the amount agreed to by the Parties under the Development Plan and/or Marketing Plan for such Wind-Down Period and that the Parties shall use commercially reasonable efforts to minimize the costs for the Wind-Down Period. NVS will be under no obligation to pay any milestone payments to the extent the applicable milestones are achieved during the Wind-Down Period. Notwithstanding the foregoing, NVS will not be responsible for ongoing costs incurred during the Wind-Down Period if HGS agrees to an agreement with a new collaborator for the Collaboration Product during the Wind-Down Period.

Any termination by any Party under this Clause and the effects of termination provided herein shall be without prejudice to any damages or other legal or equitable remedies to which it may be entitled from the other Party.

(b) Either HGS or NVS may terminate this Agreement on written notice if an Insolvency Event occurs in relation to the other Party. In any event when a Party first becomes aware of the likely occurrence of any Insolvency Event in regard to that Party, it shall promptly so notify the other Party in sufficient time to give the other Party sufficient notice to protect its interests under this Agreement.

15.4 Effects of Termination by HGS for NVS Breach or Termination by NVS Without Cause. If HGS terminates this Agreement in accordance with Section 15.3 or if NVS terminates this Agreement for convenience in accordance with Section 15.2, then (i) all rights and licenses granted by either Party to the other hereunder shall immediately terminate, and neither Party shall have any right to any continued use of the Patent Rights and Know-how of the other Party; (ii) NVS, upon request of HGS and free of charge, shall execute any document reasonably necessary to transfer to HGS all reasonably available data, information, results, clinical trials, regulatory documents, support documentation and supplies developed by or on behalf of NVS under this Agreement necessary for HGS to continue the Development or Commercialization of the Collaboration Product, including all applications submitted to, or approvals obtained from, any Regulatory Authority for purposes of seeking Marketing Approval for the Collaboration Product, or for making, using or selling the Collaboration Product, and (iii) to the extent reasonably available, any studies in progress pursuant to the Development

NVS shall not be liable to HGS for any reason whatsoever as a consequence of any license from NVS or HGS’ utilizing any information or documents conveyed as provided in this Section. Upon such a termination of this Agreement, NVS shall be entitled, during the [***] days following the termination of this Agreement, to finish any work-in-progress and to sell any inventory of the Collaboration Product that remains on hand as of the date of the termination, so long as NVS pays HGS the royalties applicable to said subsequent sales in accordance with the terms and conditions set forth in this Agreement. Except as expressly provided in this Section, upon termination by NVS pursuant to Section 15.2, NVS shall not incur any additional costs, expenses or liabilities of any kind under this Agreement except for those costs, expenses or liabilities which have matured and accrued as of the effective date of the termination.

15.5 Effects of Termination by NVS for HGS Breach.

15.6 Insolvency. All rights and licenses granted under or pursuant to this Agreement by NVS or HGS are, and shall otherwise be deemed to be, for purposes of Section 365(n) of the U.S. Bankruptcy Code, licenses of right to “intellectual property” as defined under Section 101 of the U.S. Bankruptcy Code. The parties agree that the parties, as licensees of such rights under this Agreement, shall retain and may fully exercise all of their rights and elections under the U.S. Bankruptcy Code. The parties further agree that, in the event of the commencement of a bankruptcy proceeding by or against either Party under the U.S. Bankruptcy Code, the Party hereto that is not a party to such proceeding shall be entitled to a complete duplicate of (or complete access to, as appropriate) any such intellectual property and all embodiments of such intellectual property, which, if not already in the non-subject Party’s possession, shall be promptly delivered to it (a) upon

any such commencement of a bankruptcy proceeding upon the non-subject Party’s written request therefor, unless the Party subject to such proceeding elects to continue to perform all of its obligations under this Agreement or (b) if not delivered under (a) above, following the rejection of this Agreement by or on behalf of the Party subject to such proceeding upon written request therefor by the non-subject Party.

15.7 Divestiture by a Party. If in connection with any proposed acquisition or merger or inquiry of a Governmental Authority, a Party (the “Divesting Party”) determines that in order to facilitate clearance or obtain approval from any Governmental Authority with responsibility for enforcing antitrust or competition laws regarding such acquisition or merger or inquiry, it would be advisable, in the Divesting Party’s business judgment, to assign or sublicense or otherwise transfer (any such assignment, sublicense or transfer, a “Divestiture Transaction”) the Divesting Party’s rights and obligations under this Agreement to any third party, the Divesting Party shall notify the other Party (the “Non-Divesting Party”) thereof (“Notice of Divestiture”). If the Divesting Party provides such notice in accordance with this Section, the Non-Divesting Party shall have a period of [***] to determine whether it wishes to negotiate an Agreement for such Collaboration Product. If the Non-Divesting Party elects to exercise its right to negotiate, the Parties shall thereafter have [***] to negotiate in good faith and finalize the terms of an agreement. If the Parties are not able to finalize such agreement during such [***] period, then the Divesting Party will be free to offer the Collaboration Product to potential Third Party sublicensees; provided, that the Divesting Party may not enter into an agreement with any Third Party on financial terms that, taken as a whole, are less favorable to the Non-Divesting Party than those last offered by the Divesting Party without first offering such terms to the Non-Divesting Party.

15.8 Effects of Termination pursuant to Section 15.1. Upon expiration of this Agreement in accordance with Section 15.1, then all rights and licenses granted by HGS to NVS hereunder shall continue as fully-paid up, royalty-free, perpetual, transferable, irrevocable rights.

15.9 The right of either Party to terminate this Agreement as herein above provided shall not be affected in any way by its waiver of or failure to take action with respect to any previous default. Any such termination shall be without prejudice to any further rights and remedies vested in the parties. The license rights granted herein shall survive the bankruptcy or reorganization of either Party.

15.10 Expiration or termination of this Agreement for any reason, except as otherwise stated under this Agreement, shall be without prejudice to:

(a) Articles 13, 17, 18 and 19; which shall survive termination or expiration in accordance with their respective terms; and

(b) either Party’s obligation to make any payments due pursuant to this Agreement which accrue prior to termination, and at the time of termination, all such payments due shall be made in full.

The provisions of this section shall survive and remain in full force and effect after any termination, expiration or cancellation of this Agreement and NVS’ obligation hereunder shall apply whether or not such Claims are rightfully brought.
