The indemnity agreement in this Article 11 shall not apply to amounts paid in settlement of any loss, claim, damage, liability or action if such settlement is effected without the consent of the Indemnitor, which consent shall not be withheld unreasonably. The failure to deliver notice to the Indemnitor within a reasonable time after the commencement of any such action, if materially prejudicial to its ability to defend such action, shall relieve such Indemnitor of any liability to the Indemnitee under this Article 11, 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 Article 11. The Indemnitee under this Article 11, its employees and agents, shall cooperate fully with the Indemnitor and its legal representatives in the investigation of any action, claim or liability covered by this indemnification. 11.4 Novartis Insurance. Novartis shall maintain product liability insurance with respect to development, manufacture and sales of Novartis Products by Novartis in such amount as Novartis customarily maintains with respect to sales of its other products. Novartis shall maintain such insurance for so long as it continues to manufacture or sell any Novartis Products, and thereafter for so long as Novartis maintains insurance for itself covering such manufacture or -33- <PAGE> CONFIDENTIAL TREATMENT sales. Novartis shall provide Cubist with written evidence of such insurance upon request by Cubist. 11.5 Cubist Insurance. Cubist shall maintain product liability insurance with respect to development, manufacture and sales of Cubist Products by Cubist in such amount as Cubist customarily maintains with respect to sales of its other products. Cubist shall maintain such insurance for so long as it continues to manufacture or sell any Cubist Products, and thereafter for so long as Cubist maintains insurance for itself covering such manufacture or sales. Cubist shall provide Novartis with written evidence of such insurance upon request by Novartis. ARTICLE 12 TERM AND TERMINATION 12.1 The Research Program. 12.1.1 Expiration of the Research Program.

Neither Party shall be held liable or responsible to the other Party nor be deemed to have defaulted under or breached this Agreement for failure or delay in fulfilling or performing any term of this Agreement when such failure or delay is caused by or results from causes beyond the reasonable control of the affected Party, including but not limited to fire, floods, embargoes, war, acts of war (whether war is declared or not), insurrections, riots, civil commotions, strikes, lockouts or other labor disturbances, acts of God or acts, omissions or delays in acting by any governmental authority or the other Party; provided, however, that the Party so affected shall use reasonable commercial efforts to avoid or remove such causes of nonperformance, and shall continue to perform hereunder with reasonable dispatch whenever such causes are removed. Either Party shall provide the other Party with prompt written notice of any delay or failure to perform that occurs by reason of force majeure. The Parties shall mutually seek a resolution of the delay or the failure to perform as noted above. 13.2 Assignment. This Agreement may not be assigned or otherwise transferred by either Party without the prior written consent of the other Party, which consent shall not be unreasonably withheld or delayed; provided, however, that each of the Parties may, without such consent, assign this Agreement and its rights and obligations hereunder to its Affiliates or in connection with the transfer or sale of all or substantially all of the portion of its business to which this Agreement relates, or in the event of its merger or consolidation or change in control or similar transaction or, in the case of Cubist, the creation of a special purpose corporation or research and development limited partnership.

In case such valid provisions cannot be agreed upon, the invalidity of one or several provisions of this Agreement shall not affect the validity of this Agreement as a whole, unless the invalid provisions are of such essential importance to this Agreement that it is to be reasonably assumed that the Parties would not have entered into this Agreement without the invalid provisions. 13.4 Notices. Any consent, notice or report required or permitted to be given or made under this Agreement by one of the Parties hereto to the other shall be in writing, delivered personally or by facsimile (and promptly confirmed by personal delivery or courier) or courier, postage prepaid (where applicable), addressed to such other Party at its address indicated below, or to such other address as the addressee shall have last furnished in writing to the addressor and shall be effective upon receipt by the addressee. -37- <PAGE> CONFIDENTIAL TREATMENT If to Cubist: Cubist Pharmaceuticals, Inc. 39 Emily Street Cambridge, Massachusetts 02139 Attention: President Fax: (617) 576-0271 with a copy to: Palmer & Dodge LLP One Beacon Street Boston, Massachusetts 02109 Attention: Michael Lytton, Esq.
