11.3 Indemnification Procedure.



11.3.1 Notice. Each Party will notify promptly the other if it becomes aware of a Claim (actual or potential) by any Third Party (a Third
Party Claim) for which indemnification may be sought by that Party and will give such information with respect thereto as the other Party shall reasonably request. If any proceeding (including any governmental investigation) is instituted
involving any Party for which such Party may seek an indemnity under Section 11.1 or 11.2, as the case may be (the Indemnified Party), the Indemnified Party shall not make any admission or statement concerning such Third Party
Claim, but shall promptly notify the other Party (the Indemnifying Party) orally and in writing and the Indemnifying Party and Indemnified Party shall meet to discuss how to respond to any Third Party Claims that are the subject
matter of such proceeding. The Indemnifying Party shall not be obligated to indemnify the Indemnified Party to the extent any admission or statement made by the Indemnified Party or any failure by such Party to notify the Indemnifying Party of the
claim materially prejudices the defense of such claim.



11.3.2
Defense of Claim. If the Indemnifying Party elects to defend or, if local procedural rules or laws do not permit the same, elects to control the defense of a Third Party Claim, it shall be entitled to do so provided it gives notice to the
Indemnified Party of its intention to do so within thirty (30) days after the receipt of the written notice from the Indemnified Party of the potentially indemnifiable Third Party Claim (the Litigation Condition); provided, that
the Indemnifying Party expressly agrees the Indemnifying Party shall be responsible for satisfying and discharging any award made to the Third Party as a result of such proceedings or settlement amount agreed with the Third Party in respect of the
Third Party Claim without prejudice to any provision in this Agreement or right at law which will allow the Indemnifying Party subsequently to recover any amount from the Indemnified Party to the extent the liability under such settlement or award
was attributable to the Indemnified Party. Subject to compliance with the Litigation Condition, the Indemnifying Party shall retain counsel reasonably



21



---

acceptable to the Indemnified Party (such acceptance not to be unreasonably withheld, refused, conditioned or delayed) to
represent the Indemnified Party and shall pay the fees and expenses of such counsel related to such proceeding. In any such proceeding, the Indemnified Party shall have the right to retain its own counsel, but the fees and expenses of such counsel
shall be at the expense of the Indemnified Party. The Indemnified Party shall not settle any claim for which it is seeking indemnification without the prior consent of the Indemnifying Party which consent shall not be unreasonably withheld, refused,
conditioned or delayed. The Indemnified Party shall, if requested by the Indemnifying Party, cooperate in all reasonable respects in the defense of such claim that is being managed and/or controlled by the Indemnifying Party. The Indemnifying Party
shall not, without the written consent of the Indemnified Party (which consent shall not be unreasonably withheld, refused, conditioned or delayed), effect any settlement of any pending or threatened proceeding in which the Indemnified Party is, or
based on the same set of facts could have been, a party and indemnity could have been sought hereunder by the Indemnified Party, unless such settlement includes an unconditional release of the Indemnified Party from all liability on claims that are
the subject matter of such proceeding. If the Litigation Condition is not met, then neither Party shall have the right to control the defense of such Third Party Claim and the Parties shall cooperate in and be consulted on the material aspects of
such defense at the each Partys own expense; provided that if the Indemnifying Party does not satisfy the Litigation Condition, the Indemnifying Party may at any subsequent time during the pendency of the relevant Third Party Claim irrevocably
elect, if permitted by local procedural rules or laws, to defend and/or to control the defense of the relevant Third Party Claim so long as the Indemnifying Party also agrees to pay the reasonable fees and costs incurred by the Indemnified Party in
relation to the defense of such Third Party Claim from the inception of the Third Party Claim until the date the Indemnifying Party assumes the defense or control thereof.



11.4 Assumption of Defense. Notwithstanding anything to the contrary contained herein, an Indemnified Party shall be
entitled to assume the defense of any Third Party Claim with respect to the Indemnified Party, upon written notice to the Indemnifying Party pursuant to this Section 11.4, in which case the Indemnifying Party shall be relieved of liability under
Section 11.1 or 11.2, as applicable, solely for such Third Party Claim and related Losses.



11.5 Limitation of Liability. IN NO EVENT SHALL EITHER PARTY BE LIABLE TO THE OTHER OR ANY OF ITS AFFILIATES, INCLUDING GSK AND ITS AFFILIATES, FOR ANY CONSEQUENTIAL, INCIDENTAL, INDIRECT, SPECIAL, PUNITIVE OR
EXEMPLARY DAMAGES (INCLUDING, WITHOUT LIMITATION, LOST PROFITS, BUSINESS OR GOODWILL) SUFFERED OR INCURRED BY SUCH OTHER PARTY OR ITS AFFILIATES, INCLUDING GSK AND ITS AFFILIATES, AND ANY PERSON IN PRIVITY WITH ANY OF THE FOREGOING, IN CONNECTION
WITH A BREACH OR ALLEGED BREACH OF THIS AGREEMENT. FOR AVOIDANCE OF DOUBT, THE FOREGOING SENTENCE SHALL NOT LIMIT THE OBLIGATIONS OF EITHER PARTY TO INDEMNIFY THE OTHER PARTY OR GSK UNDER THIS ARTICLE 11 FROM AND AGAINST CLAIMS OF THIRD PARTIES,
OTHER THAN ANY PERSON IN PRIVITY WITH ANY PARTY, GSK OR ANY OF THEIR AFFILIATES.



11.6 Insurance. During the term of this Agreement and for a period of five (5) years after its termination, each Party shall obtain and/or maintain, respectively, at its sole cost and



22

expense, liability insurance in amounts, respectively, required by applicable Laws, but in no event less than
