Pass-Through Supply Agreement for any breach of any such warranties. 
 9.3 Reciprocal Representations and Warranties. Each Party

performance of this Agreement by such Party has been duly authorized by all necessary corporate action, and the person executing this Agreement on behalf of such Party has been duly authorized to do so by all requisite corporate actions. 

9.4 Disclaimer of Warranties. EXCEPT FOR THE EXPRESS REPRESENTATIONS AND WARRANTIES SET FORTH IN SECTIONS 9.1 (ASTRAZENECA WARRANTIES),
SECTION 9.2 (RECIPROCAL REPRESENTATIONS AND WARRANTIES) OR IN THE ASSET PURCHASE AGREEMENT, EACH PARTY MAKES NO REPRESENTATIONS AND GRANTS NO WARRANTIES WITH RESPECT TO THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT, EXPRESS OR IMPLIED, EITHER IN
FACT OR BY OPERATION OF LAW, BY STATUTE OR OTHERWISE, AND ASTRAZENECA AND HORIZON EACH SPECIFICALLY DISCLAIMS ANY OTHER WARRANTIES, WHETHER WRITTEN OR ORAL, OR EXPRESS OR IMPLIED, INCLUDING ANY WARRANTY OF QUALITY OR MERCHANTABILITY, OR ANY WARRANTY
AS TO THE VALIDITY OR ENFORCEABILITY OF ANY PATENTS OR THE NON-INFRINGEMENT OF ANY INTELLECTUAL PROPERTY RIGHTS OF THIRD PARTIES. 
 9.5
Other Covenants. 
 9.5.1 Each Party shall comply with all applicable Law in performing its obligations under this
Agreement. 
 9.5.2 AstraZeneca shall not employ, contract with, or retain any person directly or indirectly to perform any services
under this Agreement if such a person (a) is under investigation by the FDA for debarment or is presently debarred by the FDA pursuant to 21 U.S.C. § 335a or its successor provisions, or (b) has a disqualification hearing pending or
has been disqualified by the FDA pursuant to 21 C.F.R. § 312.70 or its successor provisions. If, during the Term, AstraZeneca or any person employed or retained by it to perform under this Agreement (excluding any Pass-Through Supply Vendor)
(i) comes under investigation by the FDA for a debarment action or disqualification, (ii) is debarred or disqualified, or (iii) engages in any conduct or activity that could lead to any of the above-mentioned disqualification or

with the benefit of any warranties with respect to the subject matter. 

  
 13. 








 9.5.3 AstraZeneca has and will maintain (or, as applicable, will use commercially
reasonable efforts to cause the applicable Pass-Through Supply Vendors to maintain) during the Term all government permits, including, health, safety and environmental permits, necessary for the conduct of the activities that it undertakes pursuant
to this Agreement. 
 9.5.4 As between AstraZeneca and Horizon, Horizon shall be responsible for ensuring that the Product
Specifications shall comply with all applicable Regulatory Approvals, cGMPs and other applicable Law. 
 10. CONFIDENTIALITY 

10.1 General. The rights and obligations of the Parties with respect to Confidential Information disclosed by or on behalf of one Party
to the other Party hereunder shall be governed by the terms of Section 9.1 of the License Agreement. 
 11. TERM AND
TERMINATION 
 11.1 Term. The term of this Agreement will commence as of the Effective Date and, unless earlier
terminated in accordance with this Section 11 (Term and Termination), will expire on December 31, 2014 (the “Term”). 

11.2 Termination for Material Breach. In the event that either Party (the “Breaching Party”) is in material
default of any of its material obligations under this Agreement, in addition to any other right and remedy the other Party (the “Non-Breaching Party”) may have, the Non-Breaching Party may terminate this Agreement by [...***...] days’ prior written notice (such [...***...]-day period, the “Notice Period”) to the Breaching Party, specifying the breach and its claim of right to terminate;
provided, that the termination shall not become effective at the end of the Notice Period if the Breaching Party cures the breach complained about during the Notice Period (or, if such default cannot be cured within such Notice Period, if the
Breaching Party commences actions to cure such default within the Notice Period and thereafter diligently continues such actions). [...***...] If either Party initiates a dispute resolution procedure as permitted under Section 14.3 (Dispute
Resolution) to resolve the dispute for which termination is being sought and is diligently pursuing such procedure, including any arbitration following therefrom, the termination shall become effective only if and when such dispute is finally
resolved through such dispute resolution procedure. This Section 11.2 (Termination for Material Breach) defines exclusively the Parties’ right to terminate in case of any material breach of this Agreement. 

11.3 Other Termination by Horizon. Horizon may terminate this Agreement at any time at will upon one hundred twenty (120) days
prior written notice to AstraZeneca. In addition, Horizon may terminate this Agreement immediately upon written notice to AstraZeneca if (a) the Existing Regulatory Approval is suspended for any reason or (b) any Regulatory Authority

respect to AstraZeneca’s or its Affiliate’s or any Pass-Through Vendors’ Manufacturing of Supplied Products. 

11.4 Termination for Insolvency. This Agreement may be terminated by written notice by either Party at any time during the Term upon the
declaration by a court of competent jurisdiction that the other Party is bankrupt and, pursuant to the U.S. Bankruptcy Code such other Party’s assets are to be liquidated; upon the filing or institution of bankruptcy, liquidation or
receivership proceedings (other than reorganization proceedings under Chapter 11 of the U.S. Bankruptcy Code); or upon an assignment of a substantial portion of the assets for the benefit of creditors by the other Party; or in the event a receiver
or custodian is appointed for such Party’s business; provided, however, that in the case of any involuntary proceeding, such right to terminate shall only become effective if the proceeding is not dismissed within sixty (60) days
after the filing thereof. 
 11.5 Termination of License Agreement. This Agreement shall automatically terminate upon expiration or
termination of the License Agreement. 
 11.6 Consequences of Expiration and Termination. 

11.6.1 Upon expiration or termination of this Agreement, except as set forth in this Section 11.6 or Section 11.7, all
obligations of the Parties under this Agreement will terminate immediately. The use by either Party of a termination right provided for under this Agreement and in accordance with this Agreement shall not give rise to the payment of damages or any
other form of compensation or relief to the other party with respect thereto. Subject to the preceding sentence, termination of this Agreement shall not preclude either Party from claiming any other damages, compensation or relief that it may be
entitled to upon such termination or for any breach of this Agreement. 
 11.6.2 Upon expiration or termination of this Agreement

the terms of this Agreement and (b) Horizon shall promptly pay to AstraZeneca (i) the cost of AstraZeneca’s then existing inventory of Raw Materials that cannot otherwise be used in the business of AstraZeneca or returned to the
vendor without additional costs and the cost that AstraZeneca or any Pass-Through Affiliate is required to pay to a Pass-Through Supply Vendor with respect to such Pass-Through Supply Vendor’s then existing inventory of Raw Materials that
cannot otherwise be used in the business of such Pass-Through Supply Vendor or returned to the vendor without additional costs and (ii) the applicable Transfer Price for all work in process and finished Supplied Product Manufactured, but not
then delivered by AstraZeneca to Horizon; provided all such Raw Materials, work in process, and finished Supplied Product Manufactured but not then delivered by AstraZeneca to Horizon, shall be delivered to Horizon or its designee within
thirty (30) days. 
 11.7 Surviving Obligations. Expiration or termination of this Agreement will not relieve the Parties of any
obligation accruing prior to such expiration or termination. The provisions of Sections 2.3 (Technology Transfer) (only for six (6) months after the end of the Term), 9.4 (Disclaimer of Warranties), 10 (Confidentiality), 11.6 (Consequences of
Expiration 

  
 15. 








 
and Termination), 11.7 (Surviving Obligations), 12 (Indemnification and Insurance), 13 (Limitation of Liability) and 14 (Miscellaneous) will survive any expiration or termination of this
Agreement. 
 12. INDEMNIFICATION AND INSURANCE 

12.1 Indemnification by AstraZeneca. Subject to this Article 12, AstraZeneca shall indemnify, defend and hold harmless Horizon and its
Affiliates, and its and their respective licensors, licensees, officers, directors, employees and agents (collectively, “Horizon Indemnitees”) from and against any and all Losses incurred by them in connection with any and
all Litigation by Third Parties (collectively, “Third Party Claims”) arising from or occurring as a result of: (a) the gross negligence or willful misconduct of any AstraZeneca Indemnitee or (b) the breach by
AstraZeneca of any warranty, representation, covenant or agreement made by AstraZeneca in this Agreement, in each case, except to the extent such Losses result from the gross negligence or willful misconduct of any Horizon Indemnitee or the breach
by Horizon of any warranty, representation, covenant or agreement made by Horizon in this Agreement, as to which Losses each Party shall indemnify the other Party and the AstraZeneca Indemnitees or the Horizon Indemnitees, as applicable, to the
extent of its liability for such Losses. 
 12.2 Indemnification by Horizon. Subject to this Article 12, Horizon shall indemnify,
defend and hold harmless AstraZeneca and its Affiliates, and its and their respective officers, directors, employees and agents (collectively, “AstraZeneca Indemnitees”) from and against any and all Losses incurred by them in
connection with any and all Third Party Claims arising from or occurring as a result of: (a) the Exploitation or Manufacture of any Supplied Product by Horizon, its Affiliates or any of their respective Sublicensees, (b) the gross
negligence or willful misconduct of any Horizon Indemnitee, or (c) the breach by Horizon of any warranty, representation, covenant or agreement made by Horizon in this Agreement; except, in each case, to the extent such Losses result from the
gross negligence or willful misconduct of any AstraZeneca Indemnitee or the breach by AstraZeneca of any warranty, representation, covenant or agreement made by AstraZeneca in this Agreement, as to which Losses each Party shall indemnify the other
Party and the AstraZeneca Indemnitees or the Horizon Indemnitees, as applicable, to the extent of its liability for such Losses. 
 12.3
Indemnification Procedures. All indemnification claims in respect of Horizon or any Horizon Indemnitees shall be made solely by Horizon and all indemnification claims in respect of AstraZeneca or any AstraZeneca Indemnitee shall be made solely
by AstraZeneca and, in each case, shall be governed by Section 7.2 of the Asset Purchase Agreement. Notwithstanding anything herein to the contrary, the Parties’ respective indemnification obligations under this Article 12 shall not apply
to any Losses for which such Party is entitled to indemnification under the Asset Purchase Agreement (excluding for this purpose, application of the limitations in Section 7.3 of the Asset Purchase Agreement). 

12.4 Insurance. Each Party will have and maintain such types and amounts of liability insurance as is normal and customary in the
industry generally for parties similarly situated, and will upon request provide the other Party with a copy of its policies of insurance in that regard, along with any amendments and revisions thereto.

 14. MISCELLANEOUS 

14.1 AstraZeneca’s Third Party Manufacturers. The Parties acknowledge and agree that AstraZeneca plans to use the Pass-Through
Supply Vendors in connection with the supply of Supplied Products under this Agreement and that AstraZeneca’s obligations, and Horizon’s rights, under this Agreement are subject to the terms and conditions of the applicable Pass-Through
Supply Agreements. AstraZeneca shall not amend any Pass-Through Supply Agreement in a manner that materially and adversely affects Horizon’s rights under this Agreement and the Quality Agreement nor terminate any such Pass-Through Supply
Agreement if such termination materially and adversely affects Horizon’s rights under this Agreement, in either case, without prior written consent of Horizon, such consent not to be unreasonably conditioned, withheld or delayed. 

14.2 Governing Law, Jurisdiction, Venue and Service. 

14.2.1 Governing Law. This Agreement shall be governed by and construed in 

  
  

	***	Confidential Treatment Requested 

 17. 








 
accordance with the Laws of the State of New York, excluding any conflicts or choice of Law rule or principle that might otherwise refer construction or interpretation of this Agreement to the
substantive Law of another jurisdiction. 
 14.2.2 Jurisdiction. Subject to Section 14.3 and 14.13, the Parties hereby
irrevocably and unconditionally consent to the exclusive jurisdiction of the courts of the State of New York and the United States District Court for the Southern District of New York for any action, suit or proceeding (other than appeals therefrom)
arising out of or relating to this Agreement, and agree not to commence any action, suit or proceeding (other than appeals therefrom) related thereto except in such courts. The Parties irrevocably and unconditionally waive their right to a jury
trial. 
 14.2.3 Venue. Subject to Section 14.3 and 14.13, the Parties further hereby irrevocably and unconditionally
waive any objection to the laying of venue of any action, suit or proceeding (other than appeals therefrom) arising out of or relating to this Agreement in the courts of the State of New York or in the United States District Court for the Southern
District of New York, and hereby further irrevocably and unconditionally waive and agree not to plead or claim in any such court that any such action, suit or proceeding brought in any such court has been brought in an inconvenient forum. 

14.2.4 Service. Each Party further agrees that service of any process, summons, notice or document by registered mail to its
address set forth in Section 14.4 shall be effective service of process for any action, suit or proceeding brought against it under this Agreement in any court. 

14.3 Dispute Resolution. 

14.3.1 Except as provided in Section 14.13, if a dispute arises between the Parties in connection with or relating to this
Agreement or any document or instrument delivered in connection herewith (a “Dispute”), then either Party shall have the right to refer such Dispute to the Senior Officers for attempted resolution by good faith negotiations
during a period of 10 Business Days. Any final decision mutually agreed to by the Senior Officers in writing shall be conclusive and binding on the Parties. 

14.3.2 If such Senior Officers are unable to resolve any such Dispute within such 10-Business Day period, either Party shall be free to
institute binding arbitration in accordance with this Section 14.3.2 upon written notice to the other Party (an “Arbitration Notice”) and seek such remedies as may be available. Upon receipt of an Arbitration Notice by a
Party, the applicable Dispute shall be resolved by final and binding arbitration before a panel of three (3) experts with relevant industry experience (the “Arbitrators”). Each of Horizon and AstraZeneca shall promptly
select one Arbitrator, which selections shall in no event be made later than thirty (30) days after the notice of initiation of arbitration. The third Arbitrator shall be chosen promptly by mutual agreement of the Arbitrator chosen by Horizon
and the Arbitrator chosen by AstraZeneca, but in no event later than thirty (30) days after the date that the last of such Arbitrators was appointed. The Arbitrators shall determine what discovery will be permitted, consistent with the goal of
reasonably controlling the cost and time that the Parties must expend for discovery; provided that the Arbitrators shall permit such discovery as they deem necessary 

  
 18. 








 
to permit an equitable resolution of the Dispute. The arbitration shall be administered by the American Arbitration Association (“AAA”) (or its successor entity) in
accordance with the then current Commercial Rules of the American Arbitration Association including the Procedures for Large, Complex Commercial Disputes (including the Optional Rules for Emergency Measures of Protection), except as modified in this
Agreement. The arbitration shall be held in New York, New York, USA, and the Parties shall use reasonable efforts to expedite the arbitration if requested by either Party. The Arbitrators shall, within fifteen (15) days after the conclusion of
the arbitration hearing, issue a written award and statement of decision describing the essential findings and conclusions on which the award is based, including the calculation of any damages awarded. The decision or award rendered by the
Arbitrators shall be final and non-appealable, and judgment may be entered upon it in accordance with applicable Law in the State of New York or any other court of competent jurisdiction. The Arbitrators shall be authorized to award compensatory
damages, but shall not be authorized to reform, modify or materially change this Agreement or any other agreements contemplated hereunder. 

14.3.3 Each Party shall bear its own counsel fees, costs, and disbursements arising out of the dispute resolution procedures described
in this Section 14.3, and shall pay an equal share of the fees and costs of the Arbitrators and all other general fees related to any arbitration described in Section 14.3.3; provided, however, the
Arbitrators shall be authorized to determine whether a Party is the prevailing Party, and if so, to award to that prevailing Party reimbursement for its reasonable counsel fees, costs and disbursements (including expert witness fees and expenses,
photocopy charges, or travel expenses) and/or the fees and costs of the Arbitrators. Unless the Parties otherwise agree in writing, during the period of time that any arbitration proceeding described in Section 14.3.3 is pending under this
Agreement, the Parties shall continue to comply with all terms and provisions of this Agreement. All arbitration proceedings and decisions of the Arbitrator under this 14.3 shall be deemed Confidential Information of both Parties under
Section 10. For clarity, nothing contained in this Agreement shall deny either Party the right to seek injunctive or other equitable relief from a court of competent jurisdiction in the context of a bona fide emergency or prospective
irreparable harm, and such an action may be filed and maintained notwithstanding any ongoing arbitration proceeding.  
 14.4
Notice Requirements. Any notice, request, demand, waiver, consent, approval or other communication permitted or required under this Agreement (each, a “Notice”) shall be in writing, shall refer specifically to this
Agreement and shall be deemed given only if delivered by hand or sent by facsimile transmission (with transmission confirmed) or by internationally recognized overnight delivery service that maintains records of delivery, addressed to the Parties at
their respective addresses specified in this Section 14.4 or to such other address as the Party to whom notice is to be given may have provided to the other Party at least five (5) days’ prior to such address taking effect in
accordance with this Section 14.4. Such Notice shall be deemed to have been given as of the date delivered by hand or internationally recognized overnight delivery service or confirmed that it was received by facsimile (with receipt confirmed
by telephone or email). Any Notice delivered by facsimile shall be confirmed by a hard copy delivered as soon as practicable thereafter.

14.5 Force Majeure. Neither Party shall be held liable or responsible to the other Party or be deemed to have defaulted under or
breached this Agreement for failure or delay in fulfilling or performing any term of this Agreement if such failure or delay is caused by or results from events beyond the reasonable control of the non-performing Party, including fires, floods,
earthquakes, hurricanes, embargoes, shortages, epidemics, quarantines, war, acts of war (whether war be declared or not), terrorist acts, insurrections, riots, civil commotion, strikes, lockouts, or other labor disturbances (whether involving the
workforce of the non-performing Party or of any other Person), acts of God or acts, omissions or delays in acting by any 

  
 20. 








 
Governmental Authority (except to the extent such delay results from the breach by the non-performing Party or any of its Affiliates of any term or condition of this Agreement) (each, a
“Force Majeure Event”). The non-performing Party shall notify the other Party of such Force Majeure Event within thirty (30) days after such occurrence by giving written notice to the other Party stating the nature of
the Force Majeure Event, its anticipated duration, and any action being taken to avoid or minimize its effect. The suspension of performance shall be of no greater scope and no longer duration than is necessary and the non-performing Party shall use
commercially reasonable efforts to remedy its inability to perform. 
 14.6 No Benefit to Third Parties. The covenants and agreements
set forth in this Agreement are for the sole benefit of the Parties and their successors and permitted assigns, and, except for the rights of Horizon Indemnitees and AstraZeneca Indemnitees under Article 12, they shall not be construed as conferring
any rights on any other Persons. 
 14.7 Waiver and Non-Exclusion of Remedies. Any term or condition of this Agreement may be waived
at any time by the Party that is entitled to the benefit thereof, but no such waiver shall be effective unless set forth in a written instrument duly executed by or on behalf of the Party waiving such term or condition. The waiver by either Party of
any right hereunder or of the failure to perform or of a breach by the other Party shall not be deemed a waiver of any other right hereunder or of any other breach or failure by said other Party whether of a similar nature or otherwise.  

14.8 Assignment. Except as expressly set forth in this Agreement, neither Party shall have the right or the power to assign, in whole or
in part, any of its rights, or delegate the performance of any of its obligations, under this Agreement without the prior written authorization of the other Party, which authorization shall not be unreasonably withheld, conditioned or delayed, and
any assignment or delegation of this Agreement or any of such rights or obligations without such authorization shall be void and of no effect; provided, however, that either Party may assign the Agreement,
in whole or in part, to an Affiliate without the prior written authorization of the other Party; and provided, further, that either Party shall have the right to assign this Agreement, in whole or in part,
in connection with a merger or other acquisition of the capital stock or all or substantially all of its assets, without the prior written authorization of the other Party. Any permitted assignment or delegation hereunder by a Party shall not
relieve such Party of any of its obligations under this Agreement (whether by operation of law or otherwise), unless, with respect an assignment to a Third Party, such assignee agrees in writing to assume such Party’s obligations under this
Agreement, in which case such Party shall be relieved of its obligations hereunder from and after the effective date of such assignment and assumption. Subject to the foregoing, this Agreement shall be binding upon, inure to the benefit of, and be
enforceable by, the Parties and their respective successors and permitted assigns. 
 14.9 Use of Affiliates. Either Party
shall have the right to exercise its rights and perform its obligations under this Agreement either itself or through any of its Affiliates without authorization of the other Party. For clarity, AstraZeneca is permitted to perform its obligations
hereunder using any Pass-Through Supply Vendor. 

  
 21. 








 14.10 Amendment. This Agreement may not be modified, amended, altered or supplemented
except upon the execution and delivery of a written agreement executed by both Parties. 
 14.11 Independent Contractors. In
the exercise of their respective rights, and the performance of their respective obligations, under this Agreement, the Parties are, and shall remain, independent contractors. Nothing in this Agreement shall be construed to constitute the Parties as
partners, joint venturers, or participants in a joint enterprise or undertaking, or to constitute either of the Parties as the agent of the other Party for any purpose whatsoever. Neither Party shall bind, or attempt to bind, the other Party hereto
to any contract or the performance of any other obligation, or represent to any Third Party that it is authorized to enter into any contract or binding obligation on behalf of the other Party hereto. 

14.12 Severability. If any provision of this Agreement is held to be illegal, invalid or unenforceable under any present or future Law,
and if the rights or obligations of either Party under this Agreement will not be materially and adversely affected thereby, (a) such provision shall be fully severable, (b) this Agreement shall be construed and enforced as if such
illegal, invalid or unenforceable provision had never comprised a part hereof, (c) the remaining provisions of this Agreement shall remain in full force and effect and shall not be affected by the illegal, invalid or unenforceable provision or
by its severance herefrom and (d) in lieu of such illegal, invalid or unenforceable provision, there shall be added automatically as a part of this Agreement a legal, valid and enforceable provision as similar in terms to such illegal, invalid
or unenforceable provision as may be possible and reasonably acceptable to the Parties. 
 14.13 Equitable Relief. The Parties
agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the Parties shall be entitled to
an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in any court of the United States or any state having jurisdiction, this being in addition to any other remedy
to which they are entitled at law or in equity. Each Party hereby waives (a) any requirement that the other Party post a bond or other security as a condition for obtaining any such relief, and (b) any defenses in any action for specific
performance, including the defense that a remedy at law would be adequate. 
 14.14 English Language. This Agreement shall be
written and executed in, and all other communications under or in connection with this Agreement shall be in, the English language. Any translation into any other language shall not be an official version thereof, and in the event of any conflict in
interpretation between the English version and such translation, the English version shall control. 
 14.15 Counterparts. This
Agreement may be executed in any number of counterparts, and each such counterpart hereof shall be deemed to be an original instrument, but all such counterparts together shall constitute but one agreement. Delivery of an executed counterpart of a
signature page of this Agreement by facsimile or other electronic transmission shall be effective as delivery of a manually executed original counterpart of this Agreement. 

14.16 Entire Agreement. This Agreement, together with the Schedules and Exhibits 

  
 22. 








 
expressly contemplated hereby and attached hereto, the Ancillary Agreements, the Confidentiality Agreement and the other agreements, certificates and documents delivered in connection herewith or
therewith or otherwise in connection with the transactions contemplated hereby and thereby, contain the entire agreement between the Parties with respect to the transactions contemplated hereby or thereby and supersede all prior agreements,
understandings, promises and representations, whether written or oral, between the Parties with respect to the subject matter hereof and thereof. In the event of any inconsistency between any such Schedules and Exhibits and this Agreement, the terms
of this Agreement shall govern. 
 14.17 Construction. Except where the context otherwise requires, wherever used, the singular
includes the plural, the plural the singular, the use of any gender shall be applicable to all genders and the word “or” is used in the inclusive sense (and/or). The captions of this Agreement are for convenience of reference only and in
no way define, describe, extend or limit the scope or intent of this Agreement or the intent of any provision contained in this Agreement. The term “including” as used herein does not limit the generality of any description preceding such
term. The language of this Agreement shall be deemed to be the language mutually chosen by the Parties and no rule of strict construction shall be applied against either Party. Unless otherwise specified or where the context otherwise requires,
(a) references in this Agreement to any Article, Section, Schedule or Exhibit are references to such Article, Section, Schedule or Exhibit of this Agreement; (b) references in any Section to any clause are references to such clause of such
Section; (c) “hereof,” “hereto,” “hereby,” “herein” and “hereunder” and words of similar import when used in this Agreement refer to this Agreement as a whole and not to any particular provision
of this Agreement; (d) references to a Person are also to its permitted successors and assigns; (e) references to a Law include any amendment or modification to such Law and any rules or regulations issued thereunder, in each case, as in
effect at the relevant time of reference thereto; (f) references to any agreement, instrument or other document in this Agreement refer to such agreement, instrument or other document as originally executed or, if subsequently amended, replaced
or supplemented from time to time, as so amended, replaced or supplemented and in effect at the relevant time of reference thereto; and (g) references to monetary amounts are denominated in United States Dollars.
