(e) Shire shall take all reasonable steps to recover any additional VAT liability from the same local Tax Authorities by submitting regular claims. Sangamo shall provide all reasonably necessary assistance to facilitate the recovery of this tax.

The Indemnitee, its employees and agents, shall reasonably cooperate with the Indemnitor and its legal representatives in the investigation of any claim, demand, action or other proceeding covered by thisArticle 12.

The foregoing shall include, without limitation, transferring, upon request of Sangamo, any agreements with Third Party suppliers or vendors that specifically cover the supply or sale of Terminated Products. If any such contract between Shire and a Third Party is not assignable to Sangamo (whether by such contract’s terms or because such contract does not relate specifically to Terminated Products) but is otherwise reasonably necessary or useful for Sangamo to commence or continue developing, manufacturing, or commercializing Terminated Products or if Shire manufactures the Terminated Product itself (and thus there is no contract to assign), then Shire shall reasonably cooperate with Sangamo to negotiate for the continuation of such license and/or supply from such entity, and Shire shall supply such Terminated Product, as applicable, to Sangamo, for a reasonable period (not to exceed twelve (12) months) until Sangamo establishes an alternative, validated source of supply for the Terminated Products.

MISCELLANEOUS

15.1 Governing Law. This Agreement shall be governed by the laws of Delaware without regard to its choice of law principles,provided, that the United Nations Convention on Contracts for the International Sale of Goods shall not apply.

15.2 Dispute Resolution. Matters within the authority of the JSC shall be resolved as provided inSection 4.4. For matters outside the authority of the JSC:

(a)Notice of Dispute. The Parties recognize that a bona fide dispute as to certain matters may from time to time arise during the term of this Agreement that relates to either Party’s rights and/or obligations hereunder. In the event of any dispute between the Parties with respect to any matter relating to this Agreement, one Party may provide the other Party with a notice of dispute.

(b) Upon a Party’s receipt of a notice of dispute, the Parties shall first use their good faith efforts to resolve such dispute among themselves without resorting to Executive Resolution.

(c)Executive Resolution. In the event that such dispute is not resolved within thirty (30) days of providing a notice of dispute, the dispute shall be taken to the Chief Executive Officer or an Executive Vice President of Sangamo and a Senior Vice President of Shire for resolution. If these individuals are unable to resolve the dispute within thirty (30) days of the request for such meeting, then the Parties shall be free to pursue any avenue available to them under law or equity to resolve the dispute.

15.3 Assignment. Neither this Agreement nor any right or obligation hereunder may be assigned or delegated, in whole or part, by either Party without the prior express written consent of the other, which consent shall not be withheld unreasonably;provided,that either Party may assign or delegate any right or obligation hereunder, in whole or in part, to any of its Affiliates so long as such entity remains an Affiliate; provided, however, that the assigning Party shall remain liable for its obligations hereunder to the extent not fulfilled by assignee. Either Party may assign this Agreement in its entirety to a successor in interest in connection with a Change of Control of such Party.Sections 4.6 and 7.3shall be applicable upon a Change of Control of Sangamo. Any permitted assignee shall assume all obligations of its assignor under this Agreement, and any permitted assignment shall be binding on the successors of the assigning Party. Any purported assignment in violation of thisSection 15.3 shall be void.

Notwithstanding the foregoing, Sangamo shall not assign or delegate any right or obligation in full or in part to an Affiliate incorporated in Switzerland without Shire’s prior written consent, which Shire shall not unreasonably withhold, other than in connection with a Change of Control. For the avoidance of doubt, a disadvantageous tax implication for Shire constitutes a reasonable reason to withhold consent.

15.4 Independent Contractors. The relationship of the Parties hereto is that of independent contractors. Neither Party hereto shall be deemed to be the agent, partner or joint venturer of the other for any purpose as a result of this Agreement or the transactions contemplated thereby.

15.5 Further Actions. Each Party agrees to execute, acknowledge and deliver such further documents and instruments and to perform all such other acts as may be necessary or appropriate in order to carry out the purposes and intent of this Agreement.

NOTHING IN THISSECTION 15.8 IS INTENDED TO LIMIT OR RESTRICT THE DAMAGES AVAILABLE FOR A BREACH OFARTICLE 11 OR THE INDEMNIFICATION RIGHTS OR OBLIGATIONS OF EITHER PARTY UNDERARTICLE 12 ABOVE.

15.9 Complete Agreement. This Agreement constitutes the entire agreement between the Parties regarding the subject matter hereof, and all prior representations, understandings and agreements regarding the subject matter hereof, either written or oral, expressed or implied, are superseded and shall be of no effect. The foregoing shall not be interpreted as a waiver of any remedies available to either Party as a result of any breach, prior to the Effective Date, by the other Party of its obligations pursuant to the CDA.

15.10 Counterparts. This Agreement may be executed in counterparts, each of which shall be deemed to be an original and together shall be deemed to be one and the same agreement.

15.11 Headings. The captions to the several sections hereof are not a part of this Agreement, but are included merely for convenience of reference only and shall not affect its meaning or interpretation.

15.12 Construction. This Agreement was negotiated and executed in English, and the original language version shall be controlling; all communications and notices hereunder shall be in English. The Parties acknowledge that they have both had the opportunity to negotiate regarding any issues in connection with this Agreement that were of concern to them and,

therefore, expressly waive the benefit of any presumption that ambiguities should be construed in favor of or against either Party. Except where the context otherwise requires, the use of any gender herein shall be deemed to be or include the other genders, the use of the singular shall be deemed to include the plural (and vice versa) and the word “or” is used in the inclusive sense. The words “include”, “includes” and “including” shall be deemed to be followed by the phrase “without limitation.” The word “will” shall be construed to have the same meaning and effect as the word “shall.” Unless the context requires otherwise, (a) any definition of or reference to any agreement, instrument or other document herein shall be construed as referring to such agreement, instrument or other document as from time to time amended, supplemented or otherwise modified (subject to any restrictions on such amendments, supplements or modifications set forth herein), (b) any reference herein to any Person shall be construed to include the Person’s successors and assigns, (c) the words “herein”, “hereof” and “hereunder”, and words of similar import, shall be construed to refer to this Agreement in its entirety and not to any particular provision hereof and (d) all references herein to sections or Exhibits shall be construed to refer to sections or Exhibits of this Agreement.

15.13 Amendment. No amendment, modification or supplement of any provision of this Agreement shall be valid or effective unless made in writing and signed by a duly authorized officer of each Party.

15.14 Waiver.No provision of the Agreement shall be waived by any act, omission or knowledge of a Party or its agents or employees except by an instrument in writing expressly waiving such provision and signed by a duly authorized officer of the waiving Party. The waiver by either of the Parties of any breach of any provision hereof by the other Party shall not be construed to be a waiver of any succeeding breach of such provision or a waiver of the provision itself.

15.15 Severability.If any clause or portion thereof in this Agreement is for any reason held to be invalid, illegal or unenforceable, the same shall not affect any other portion of this Agreement, as it is the intent of the Parties that this Agreement shall be construed in such fashion as to maintain its existence, validity and enforceability to the greatest extent possible. In any such event, this Agreement shall be construed as if such clause or portion thereof had never been contained in this Agreement, and there shall be deemed substituted therefor such provision as will most nearly carry out the intent of the Parties as expressed in this Agreement to the fullest extent permitted by applicable law.
