Other Product, Product (or any Other Product) inserts and advertising, marketing, promotional or other materials bearing any of the Licensed Trademarks as AstraZeneca may reasonably request to achieve compliance with clause (a), and (c) refrain

 7.1.4 Horizon acknowledges and agrees that no ownership rights are vested or created in the
Licensed Trademarks anywhere in the world by the licenses and other rights granted in this Agreement (including, for clarity, under Section 2.1 of this Agreement) and that all goodwill generated in connection with the use of the Licensed
Trademarks by Horizon, its Affiliates, Sublicensees, and distributors shall inure solely for and to the benefit of AstraZeneca. 

7.2 Approval Procedures. 
 7.2.1 During the Term, if Horizon desires to use any variation or derivative of an existing Licensed Trademark on, or in connection with the Exploitation of, the Product or any Other Product in the
Horizon Territory, Horizon shall submit such variation or derivation to AstraZeneca for its approval, which approval may be granted or withheld in AstraZeneca’s sole discretion. If AstraZeneca approves such variation or derivation, then upon
such approval by AstraZeneca, such variation or derivation shall be deemed a Licensed Trademark and subject to the terms hereof. AstraZeneca shall respond to each such submission within [...***...] after AstraZeneca’s receipt of each such request for approval. With respect to any variation or derivation of any existing Licensed Trademark that
Horizon submits to AstraZeneca, Horizon shall be responsible for conducting a commercially reasonable trademark clearance search and assessing the availability of any such variation or derivation for use on, and registration for, the Product or any
Other Product in the Horizon Territory and shall submit the results of such search and assessment to AstraZeneca when it submits such variation or derivation to AstraZeneca for its approval. 

7.2.2 At AstraZeneca’s reasonable request with respect to timing of delivery, Horizon shall, and shall cause its Affiliates,
Sublicensees and distributors to, furnish to AstraZeneca representative samples of all goods and all Product Labeling, Product packaging, Product inserts and advertising, marketing, promotional or other materials bearing any of the Licensed
Trademarks for registration, renewal and quality control purposes, including web pages, brochures and stationery. 
 7.3
Clearance, Registration, Prosecution and Maintenance of Licensed Trademarks. 
 7.3.1 AstraZeneca shall be
responsible for the registration, prosecution and maintenance of the Licensed Trademarks in the Horizon Territory. All registrations and applications therefor shall be filed, prosecuted, registered and maintained in the name, and for the benefit, of
AstraZeneca. All costs and expenses of clearing, registering, prosecuting and maintaining the Licensed Trademarks in the Horizon Territory shall be borne solely by AstraZeneca. AstraZeneca shall (a) provide Horizon from time to time[...***...]
a written report summarizing the current status of all applications and registrations for the Licensed Trademarks in the Horizon Territory; (b) notify Horizon promptly of, and consult with Horizon with respect to, any material, substantive
issue or any opposition, cancellation, invalidity or other proceeding that may be raised or asserted against any application or registration for any Licensed Trademark within the Horizon Territory prior to taking any action in response thereto; and
(c) consult with Horizon at least [...***...] prior to (i) taking any action to abandon or withdraw any application for any Licensed Trademark, or (ii)

  
  

	***	Confidential Treatment Requested 

 - 21 - 








 
permitting any registration for any Licensed Trademark to lapse, expire or be cancelled. 
 7.3.2 If AstraZeneca plans to cease, or ceases, the registration, prosecution and maintenance of a Licensed Trademark in the Horizon Territory, AstraZeneca shall notify Horizon in writing at least [...***...] in advance of the due date of any action that is required with respect thereto and, in such event, Horizon
may elect (but shall not be obligated), on written notice to AstraZeneca, at its sole cost and expense, to assume responsibility for and control over such registration, prosecution and maintenance in the name of Horizon. All registrations and
applications therefor shall be filed, prosecuted, registered and maintained in the name, and for the benefit, of Horizon. AstraZeneca shall execute such powers of attorney or other instruments and shall take such other actions as Horizon may
reasonably request to permit Horizon to file and prosecute any registration application and to maintain, renew, enforce and defend any registration for any such Licensed Trademarks in the Horizon Territory. 

7.4 Enforcement and Defense of Licensed Trademarks. Horizon shall have the first right, but not the obligation, to enforce
and defend the Licensed Trademarks in the Horizon Territory, including (a) after consultation with AstraZeneca, defending against any alleged, threatened or actual claim by a Third Party that the use of the Licensed Trademarks in the Horizon
Territory infringes, dilutes, misappropriates or otherwise violates any Trademark or copyright of that Third Party or constitutes unfair trade practices or any other like offense, or any other claims as may be brought by a Third Party against a
Party in connection with the use of or relating to the Licensed Trademarks with respect to the Product or any Other Product in the Horizon Territory and (b) taking such action as Horizon, after consultation with AstraZeneca, deems necessary
against a Third Party based on any alleged, threatened or actual infringement, dilution, misappropriation or other violation of, or unfair trade practices or any other like offense relating to, the Licensed Trademarks by a Third Party in the Horizon
Territory; provided that if Horizon plans to cease, or ceases, any action with respect to the enforcement or defense of any of the Licensed Trademarks in the Horizon Territory, Horizon shall notify AstraZeneca in writing at least [...***...]
in advance of the due date of any action that is required with respect thereto and, in such event, AstraZeneca may elect (but shall not be obligated), on written notice to Horizon, to assume responsibility for and control over such enforcement or
defense or to take any such action in its own name or in the name of Horizon. Notwithstanding the foregoing, as long as Horizon is Exploiting the Product or any Other Product under the Licensed Trademarks, if Horizon reasonably determines that
initiating a suit or taking other action to enforce or defend any of the Licensed Trademarks in the Horizon Territory pursuant to this Section 7.4 is not in the best interests of the Licensed Trademarks in the Horizon Territory and Horizon so
notifies AstraZeneca in writing (which notice shall include a reasonably detailed description of Horizon’s reasons for not initiating suit or taking other action to enforce or defend any of the Licensed Trademarks in the Horizon Territory
pursuant to this Section 7.4), then AstraZeneca may not enforce or defend any such Licensed Trademarks pursuant to this Section 7.4. Each enforcing or defending Party shall bear its own costs and expenses relating to any enforcement action
or defense commenced pursuant to this Section 7.4 and any settlements and judgments with respect thereto. Any damages or other amounts recovered in any such proceeding shall be retained by the Party controlling such proceeding. Each Party shall
provide to the other Party all reasonable assistance requested by the other Party in connection with any such action, defense, claim or suit under this Section 7.4, at such other Party’s cost and expense. Horizon shall obtain


  
  

	***	Confidential Treatment Requested 

 - 22 - 








 
AstraZeneca’s written consent before entering into any compromise, settlement or stipulation with respect to any such action, defense, claim or suit (such consent not to be unreasonably
withheld or delayed). In no event shall Horizon take any position or submit any argument with respect to such action, defense, claim or suit that would be reasonably expected to materially endanger, lessen, impair or undermine the Licensed
Trademarks or AstraZeneca’s rights therein or AstraZeneca’s corresponding Trademark rights outside the Horizon Territory. Each Party, at the other Party’s cost and expense, shall execute such powers of attorney or other instruments
and shall take such other actions as the other Party may reasonably request as necessary to permit the other Party to assume responsibility for and control over the enforcement or defense of the Licensed Trademarks as permitted hereunder.

 7.5 No Implied Rights. Except as expressly provided in this Article 7, Horizon shall have no right to register,
maintain, prosecute, enforce or defend the Licensed Trademarks. 
 7.6 Other Trademarks. Horizon shall have the right to
Exploit the Product and any Other Product in the Horizon Territory under a Trademark that is not a Licensed Trademark; provided, that such other Trademark is not confusingly similar to any Licensed Trademark (including any translation or
transliteration of any Licensed Trademark or any colorable imitation of any Licensed Trademark). 
 ARTICLE 8 

LICENSED DOMAIN NAMES 
 8.1 Ownership and Goodwill. Horizon acknowledges that it acquires no right, title or interest in the Licensed Domain Names other than the rights expressly set forth in this Agreement.
Horizon shall not at any time do or suffer to be done any act that would materially impair AstraZeneca’s proprietary rights in or to the Licensed Domain Names, and Horizon agrees not to directly or indirectly contest or aid in contesting the
ownership of the Licensed Domain Names, or to take any action whatsoever in derogation of AstraZeneca’s claimed rights therein. Horizon agrees and acknowledges that any and all rights and goodwill arising from use of the Licensed Domain Names
by Horizon or its Affiliates or permitted sublicensees shall inure exclusively to the benefit of AstraZeneca. 
 8.2
Registration and Maintenance. AstraZeneca shall (a) at its own expense, maintain the Primary Licensed Domain Name and (b) if requested in writing by Horizon and at Horizon’s expense, maintain the Secondary Licensed
Domain Names. Neither Party shall intentionally take, or fail to take, any action that may reasonably be expected to jeopardize the use, value, validity, or enforceability of any Licensed Domain Name; provided, that unless Horizon requests in
writing that AstraZeneca maintain a Secondary Licensed Domain Name at Horizon’s expense, AstraZeneca may allow the registration for such Secondary Licensed Domain Name to lapse. 

8.3 Control of Licensed Domain Name Websites. AstraZeneca hereby grants Horizon the sole right to administer, manage and
control the content of any website associated with, and use, the Licensed Domain Names (the “Product Websites”) under the terms of this Agreement. At Horizon’s request, AstraZeneca shall use the technical contact and


  
 - 23 -









 
server information provided by Horizon for the Licensed Domain Names. Horizon may ask from time to time that such information be further revised or updated, and AstraZeneca shall, within a
reasonable amount of time, contact the domain name registrar and revise the information accordingly. AstraZeneca shall not change the technical contact or server information for the Licensed Domain Names or take any action to direct Internet traffic
to any of the Licensed Domain Names to any servers or IP addresses other than those identified by Horizon. AstraZeneca may, from time to time, change the registrar with whom AstraZeneca has contracted to manage its domain name portfolio. Horizon
shall assist and cooperate with AstraZeneca, the old registrar or the new registrar in any way necessary to effectuate such a change of registrar. Horizon shall be responsible for the content of the Product Websites and shall ensure that all Product
Websites comply with all applicable Law. 
 8.4 Country-Specific Traffic. 

8.4.1 Horizon shall use commercially reasonable efforts to cause traffic to the Licensed Domain Names that originates within a country
outside the Horizon Territory, to be re-directed to such ccTLD as AstraZeneca may designate in writing. 
 8.4.2 AstraZeneca
shall use commercially reasonable efforts to cause traffic to vimovoglobal.com, or any other Domain Name used by or on behalf of AstraZeneca or its Affiliates in connection with Exploitation of the Products in more than one country of the
AstraZeneca Territory, that originates within a country outside the AstraZeneca Territory, to be re-directed to such ccTLD as Horizon may designate in writing. 
 8.4.3 Among other techniques that the Parties may mutually agree for re-directing traffic is the placement of a hyperlink on the homepage of the generic “.com” top-level Licensed Domain Names or
other domain names noted in Section 8.4.2, as applicable, which hyperlink shall be placed in a manner, form and style mutually agreeable to the Parties. 
 8.5 Enforcement. If Horizon becomes aware of any use, trafficking, or registration of a Licensed Domain Name other than by or on behalf of Horizon or its Affiliates or Sublicensees pursuant to this
Agreement or of any use, trafficking, or registration a confusingly similar domain name, Horizon shall promptly notify AstraZeneca of such use or trafficking or registration. AstraZeneca may take any action and institute legal, administrative or
other proceedings relating to the use, trafficking, or registration of such Licensed Domain Names as AstraZeneca, in its sole discretion, deems fit. Horizon shall execute any and all documents and to do such acts as may be reasonably necessary to
carry out such proceeding or Litigation, including becoming a nominal party to any legal action. If AstraZeneca fails to take any action within [...***...] days after notification of such use, trafficking or registration, or notifies Horizon that it
will not take any action, then Horizon may take any action and institute legal, administrative or other proceedings relating to such use, trafficking or registration as Horizon, in its sole discretion, deems appropriate. AstraZeneca agrees to
execute any and all documents and to do such acts as may be reasonably necessary to carry out such proceeding or Litigation, including becoming a nominal party to any legal action. Each Party shall bear its own costs and expenses relating to any
enforcement action commenced pursuant to this Section 8.5 and any settlements and judgments with respect thereto.

 9.1 General. 

 9.1.1 All Ancillary Confidential Information provided by one Party (or its Recipients or Affiliates) (collectively,
the “Ancillary Disclosing Party”) to the other Party (or its Recipients or Affiliates) (collectively, the “Ancillary Receiving Party”) shall be subject to and treated in accordance with the terms of this

 (a) was already known to the Ancillary Receiving Party or its Affiliates, other than under an
obligation of confidentiality, at the time of disclosure by the Ancillary Disclosing Party; 
 (b) was generally available to
the public or otherwise part of the public domain at the time of its disclosure to the Ancillary Receiving Party;

Horizon Confidential Information to any Person except those Persons to whom such disclosure is necessary in connection with any AstraZeneca Permitted Purpose. AstraZeneca shall treat, and will
cause its Affiliates and the Recipients of AstraZeneca or any of its Affiliates to treat, the Ancillary Horizon Confidential Information as confidential, using the same degree of care as AstraZeneca normally employs to safeguard its own confidential
information from unauthorized use or disclosure, but in no event less than a reasonable degree of care.

cooperate in all reasonable respects in connection with any reasonable actions to be taken for the foregoing purpose. In any event, the Party requested or required to disclose such Ancillary Confidential Information may furnish it as requested or
required pursuant to applicable Law (subject to any such protective order or other appropriate remedy) without liability hereunder, provided that such Party furnishes only that portion of the Ancillary Confidential Information which such Party is
advised by an opinion of its counsel is legally required and such Party exercises reasonable efforts to obtain reliable assurances that confidential treatment will be accorded such Ancillary Confidential Information. 

9.1.5 Nothing in this Section 9.1 shall be construed as preventing or in any way inhibiting either Party from complying with
applicable Law governing activities and obligations undertaken pursuant to this Agreement, the Asset Purchase Agreement or any other Ancillary Agreement in any manner which it reasonably deems appropriate.

MISCELLANEOUS 
 13.1 Governing Law, Jurisdiction, Venue and Service. 
 13.1.1
Governing Law. This Agreement shall be governed by and construed in 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. 
 13.1.2 Jurisdiction. Subject to Section 13.2 and
13.12, 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. 
 13.1.3 Venue. Subject to Section 13.2 and 13.12, 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.

 13.1.4 Service. Each Party further agrees that service of any process, summons,
notice or document by registered mail to its address set forth in Section 13.3.2 shall be effective service of process for any action, suit or proceeding brought against it under this Agreement in any such court. 

13.2 Dispute Resolution. 
 13.2.1 Except as provided in Section 13.12, 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. 
 13.2.2 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 13.2.2 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 experts with relevant industry experience (the

promptly by mutual agreement of the Arbitrator chosen by Horizon and the Arbitrator chosen by AstraZeneca, but in no event later than 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 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 15 days after the conclusion of the arbitration hearing, issue a written award and statement of decision describing the

other agreements contemplated hereunder. 
 13.2.3 Each Party shall bear its own counsel fees, costs, and disbursements arising
out of the dispute resolution procedures described in this Section 13.2, 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 13.2.3; 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) 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 13.2.3 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 13.2 shall be deemed Confidential Information of both Parties under Section 5 of the Asset Purchase Agreement. 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. 
 13.3 Notices. 

13.3.1 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 Section 13.3.2 or to such other address as the Party to whom notice is to be given may
have provided to the other Party at least 10 days’ prior to such address taking effect in accordance with this Section 13.3. 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.

 13.4 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 11, they shall
not be construed as conferring any rights on any other Persons. 
 13.5 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 any 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. The rights and remedies provided herein are cumulative and do not exclude any other right or remedy provided by applicable Law or otherwise available except as expressly set forth herein. 

13.6 Expenses. Except as otherwise specified herein or in the Asset Purchase Agreement or in any other Ancillary Agreement, each
Party shall bear any costs and expenses incurred by it with respect to the transactions contemplated herein. 

  
 - 33 -









 13.7 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 the assets of such assigning Party, without the prior written authorization of the other Party, subject to providing the other Party with written
notice thereof within 30 days after such assignment or delegation. 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. 

13.8 Use of Affiliates, Third Party Subcontractors. 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, or to subcontract any of its rights or obligations under this Agreement to any Third Party, without authorization of the other Party. For clarity this shall not limit
the provisions of Section 2.2 with respect to Sublicensees. 
 13.9 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. 
 13.10 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. 
 13.11 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


  
 - 34 -









 
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. 

13.12 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.

 13.13 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. 
 13.14 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. 
 13.15 Entire Agreement. This Agreement, together with the Schedules and Exhibits expressly contemplated hereby and attached hereto, the Asset Purchase Agreement and the other Ancillary
Agreements, contain the entire agreement between the Parties with respect to the transactions contemplated hereby and supersede all prior agreements, understandings, promises and representations, whether written or oral, between the Parties with
respect to the subject matter hereof. In the event of any inconsistency between any such Schedules and Exhibits and this Agreement, the terms of this Agreement shall govern. 
 13.16 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 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.
