 ARTICLE 2 

SERVICES 

2.1    Provision of Services. 

2.1.1    Subject to the terms and conditions of this Agreement, during the Transition Period, AZ shall provide or cause to
be provided to Spinco the transitional services set forth on Schedule 2.1, as such services are currently being utilized by AZ in connection with the Programs (each, a “Service” and collectively, the
“Services”), when and as reasonably requested by Spinco or its Affiliates. 
 2.1.2    If there is any
inconsistency between the terms of Schedule 2.1 and the terms of this Agreement, the terms of this Agreement shall govern. Except as expressly set forth herein, from and after the Effective Date, AZ’s and Spinco’s respective
obligations and rights with respect to the Products and the Programs shall be as set forth in the APA or the applicable other Transaction Agreements. For the avoidance of doubt, the Services do not include, and AZ shall have no obligation to
provide, any Excluded Services. 
 2.1.3    Notwithstanding anything to the contrary herein, AZ will not be required to
perform or to cause to be performed any of the Services for the benefit of any Person other than Spinco and its Affiliates. 

2.1.4    In the event that Spinco wishes to change the Services set forth on Schedule 2.1 (including adding an
additional service or services) from time to time throughout the Transition Period, the Parties shall negotiate in good faith amendments to Schedule 2.1 to this Agreement to implement such change, including reasonable changes in the
applicable Services Fees set forth on Schedule 2.1. 
 2.2    Services Performed by Affiliates and Third
Parties. AZ shall have the right to perform the Services itself, through any Affiliate or through any subcontractor; provided however that, (a) in the event that any Service is performed by AZ through a subcontractors, AZ shall notify
Spinco that such subcontractor is performing such Service and (b) in the event that any Service is performed by AZ through an Affiliate or a subcontractor, AZ shall remain responsible for the performance of such Affiliate or subcontractor as if
such Services were performed by AZ itself. AZ shall have also have the right to engage a third party contractor to substitute for AZ and contract directly with Spinco to provide any Service to Spinco upon Spinco’s prior written approval (such
approval not be unreasonably withheld or delayed), provided that AZ believes in good faith that such third party contractor is qualified and able to provide such Service consistent with the Services Standard (as defined below), in which case,
AZ’s obligation to provide such Service to Spinco, and Spinco’s obligation to pay the applicable Service Fee to AZ, shall be terminated solely to the extent such Service is carried out by such third party contractor. In such case, Spinco
agrees to enter into a customary services agreement reasonably acceptable to Spinco directly with such third party contractor to provide any such Service for the fees specified therein.

(II) WOULD BE COMPETITIVELY HARMFUL IF PUBLICLY DISCLOSED 













 2.3    Services Standard. 

2.3.1    Spinco acknowledges that AZ is not in the business of providing services to Third Parties and is entering into
this Agreement only in connection with the APA and the Securities Purchase Agreement. AZ shall, and shall cause its Affiliates and subcontractors to, provide the Services to be provided pursuant to this Agreement with substantially the same degree
of skill, quality and care utilized by AZ (or its Affiliates) in the [***] period prior to Closing in performing such activities for itself with respect to the Products and in compliance in all material respects with applicable Law (the
“Services Standard”). Under no circumstances shall AZ, its Affiliates or its or their respective employees or agents (including subcontractors) be held accountable to a greater standard of care, efforts or skill than the Services
Standard with respect to the performance of Services under this Agreement. Spinco acknowledges and agrees that (a) the Services do not include the exercise of business judgment or general management for Spinco and (b) EXCEPT AS EXPRESSLY
SET FORTH IN THIS AGREEMENT, NEITHER AZ NOR ANY OF ITS AFFILIATES MAKES ANY REPRESENTATIONS OR WARRANTIES, EXPRESS OR IMPLIED, INCLUDING ANY WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE, WITH RESPECT TO THE SERVICES. 

2.3.2    If Services to be provided to Spinco increase in scale or in scope in a material way beyond those provided to AZ
itself as of the Effective Date, AZ shall so inform Spinco and, upon Spinco’s request, the Parties shall negotiate in good faith such increased scale or scope of Services as a change to the Services as set forth in Section 2.1.4. If no
agreement is reached by the Parties in connection with such increased scale or scope of Services, AZ shall have no obligation to provide such expanded scale or scope of Services. 

2.3.3    If, in order to provide any Services under this Agreement, the Parties agree that it is necessary or advisable to
take any steps to facilitate such Services, including implementing special information technology connections or firewalls, the costs of taking such steps shall be borne by Spinco unless otherwise agreed by the Parties. 

2.4    Transitional Nature of Services; Changes. Spinco acknowledges and agrees that (a) the Services are
intended only to be transitional in nature, and shall be furnished by AZ only during the Transition Period and solely for the purpose of accommodating Spinco in connection with the transactions contemplated by the APA and (b) following the
Transition Period, Spinco will need to perform the Services (or have the Services performed by other third parties) without the involvement of AZ, its Affiliates or any of its or their respective employees or agents. Spinco acknowledges that the
Services are being furnished in support of Spinco’s personnel and under no circumstances shall AZ be required to fulfill or serve as a substitute for any personnel role of Spinco. Spinco acknowledges and agrees that AZ or its Affiliates may
make changes from time to time in its manner of performing the Services if such changes do not materially impact Spinco or the Programs and AZ or its Affiliates (a) are making similar changes in performing similar services for their own
Affiliates and (b) if applicable, furnish to Spinco substantially the same notice (in content and timing) as AZ or its Affiliates shall furnish to their own Affiliates with respect to such changes.

(II) WOULD BE COMPETITIVELY HARMFUL IF PUBLICLY DISCLOSED 













 2.5    Location of Services Provided; Travel Expenses. AZ shall
provide the Services to Spinco from locations of AZ’s choice in its sole discretion unless Services are required to be performed at a specific location identified in Schedule 2.1. Should the provision of Services require any personnel of
AZ to travel beyond 50 miles from his or her employment location, Spinco shall reimburse AZ for all reasonable travel-related costs, consistent with AZ’s travel policy. Travel time of any FTE in connection with any Service, calculated
consistent with AZ’s travel policy, shall be included in the maximum hours allocated to such Service. 

2.6    Transition Management. Within five Business Days after the Effective Date, Spinco and AZ each shall
designate an appropriate point of contact for all questions and issues relating to the Services (the “Transition Managers”). Either Party may, by written notice given to the other Party, replace its Transition Manager. As soon as
reasonably practicable following the Effective Date, the Parties shall commence planning for full transition of all Services to Spinco through the respective Transition Managers and shall designate teams and team leads with respect to each of the
functional-related Services. The Transition Managers shall meet at least once per month, or on such other schedule as mutually agreed upon by the Parties, during the Transition Period in person or telephonically in order to discuss the Services and
the status of the transition and to manage any open issues relating to the Services. 
 2.7    Cooperation. Each
of Spinco and AZ shall use commercially reasonable efforts to cooperate with each other in all matters relating to the provision and receipt of the Services. Without limiting the generality of the foregoing sentence: 

2.7.1    Such cooperation shall include AZ using commercially reasonable efforts to obtain material consents, licenses or
approvals necessary to permit AZ to perform its obligations hereunder; provided, however, that under no circumstances shall AZ be obligated to provide a Service if (a) AZ is unable to obtain necessary consents, licenses and approvals
relating to such Service on commercially reasonable terms; (b) in order to provide such Service, AZ will have an obligation to make any payments to any Third Party or incur any obligations in respect of any such consents, licenses or approvals,
which payments are not subject to reimbursement by Spinco or which other obligations are not assumed by Spinco hereunder; (c) AZ would be obligated to make any alternative arrangements in the event that any such consents, licenses or approvals
are not obtained (but only to the extent such arrangements would not be commercially reasonable); or (d) AZ would be required to seek materially broader rights or more favorable terms with respect to any consents, licenses or approvals than
those applicable immediately prior to the date hereof. 
 2.7.2    Spinco shall permit AZ, its Affiliates and its and
their respective employees and agents reasonable access during regular business hours (or otherwise upon reasonable prior notice) to such data and personnel as are involved in receiving or overseeing the Services, and records as reasonably requested
by AZ to facilitate AZ’s performance of this Agreement. 
 2.7.3    AZ shall be excused from its obligation to
provide a Service under this Agreement to the extent Spinco’s failure to perform its obligations under this Agreement materially hinders or prevents AZ’s performance of its obligation, including if the provision of a Service is dependent
or otherwise materially reliant on Spinco timely providing to AZ or any of 

  
 -5- 

[*] = CERTAIN CONFIDENTIAL INFORMATION CONTAINED IN THIS DOCUMENT, MARKED BY BRACKETS, HAS BEEN OMITTED BECAUSE THE INFORMATION (I) IS NOT MATERIAL AND
(II) WOULD BE COMPETITIVELY HARMFUL IF PUBLICLY DISCLOSED 













 
its Affiliates or subcontractors information, materials, products and like items in a manner substantially similar in nature, quality and timeliness to the information, materials, products and
like items provided to AZ, its Affiliates or subcontractors in connection with the Programs at the time of the Closing and Spinco, at its sole cost and expense, fails to so provide such information, materials, products and like items during the
Transition Period. In the event AZ believes that Spinco has failed to provide any such information, materials, products or like items or otherwise has failed to perform Spinco’s obligations under this Agreement, without limitation of AZ’s
rights and remedies hereunder, the Transition Manager of AZ shall provide notice of such alleged failure to the Transition Manager of Spinco and the Transition Managers shall discuss and work together in good faith to resolve any impact such alleged
failure may have to the provision of the Services. 
 2.8    Consents. To the extent the consent of any Third
Party is needed in order for AZ to use any resources to provide the Services, Spinco shall (a) cooperate with AZ in acquiring any such consents; (b) comply with any requirements imposed on Spinco in connection with securing such consent;
(c) comply with any restrictions imposed on the use of such resources; and (d) be responsible for any fees payable to such Third Party to the extent necessary to secure the consent. Notwithstanding the foregoing or anything herein to the
contrary, if AZ is unable to secure such consents in accordance with Section 2.7.1 or Spinco fails to comply with any requirement contemplated in Section 2.8(b), AZ’s sole liability, and Spinco’s sole remedy, will be for AZ to
assist Spinco in identifying alternate resources for such Services and will use commercially reasonable efforts to assist Spinco in obtaining such resources. AZ will notify Spinco of any requirement for Third Party consent as soon as reasonably
practicable after becoming aware of such requirement. To AZ’s Knowledge, there are no Third Party consents required for AZ to provide the Services contemplated as of the Effective Date. 

2.9    Exclusions. Subject to the Services Standard, in no event shall AZ be (a) obligated to provide any
Services that would be unlawful for AZ to provide or that would require AZ to violate applicable Law; (b) obligated to provide any Services that in AZ’s reasonable determination would create material deficiencies in AZ’s controls over
financial information or materially adversely affect the maintenance of AZ’s financial books and records or the preparation of its financial statements; (c) obligated to hire any additional employees to perform the Services or maintain the
employment of any specific employee; (d) obligated to hire replacements for employees that resign, retire or are terminated; (e) obligated to enter into retention agreements with employees or otherwise provide any incentive beyond payment
of regular salary and benefits; (f) prevented from transferring after the Effective Date any employees (other than Transferred Employees) who were supporting the Programs as of the Effective Date to support other products for AZ or its
Affiliates or to assume other roles with AZ or its Affiliates to the extent such employees are not required to provide Services; (g) prevented from determining, in its reasonable discretion, the individual employees who will provide Services;
(h) obligated to purchase, lease or license any additional equipment or software; (i) obligated to create or supply any documentation or information not currently existing or reasonably available; (j) obligated to enter into new or
additional Contracts with Third Parties or change the scope of current Contracts with Third Parties or take any actions that would result in the breach of any Third Party Contracts of AZ; or (k) obligated to provide any Service to the extent
and for so long as the performance of such Service becomes impracticable as a result of a 

  
 -6- 

[*] = CERTAIN CONFIDENTIAL INFORMATION CONTAINED IN THIS DOCUMENT, MARKED BY BRACKETS, HAS BEEN OMITTED BECAUSE THE INFORMATION (I) IS NOT MATERIAL AND
(II) WOULD BE COMPETITIVELY HARMFUL IF PUBLICLY DISCLOSED 













 
Force Majeure Event (as defined below); provided, however in the case of (b) and (k) that AZ promptly notifies Spinco of such occurrence; provided, further, that in the event AZ is unable to
provide any Service as a result of the occurrence of any event described in the foregoing clauses (a) through (k), AZ shall reasonably cooperate with Spinco with respect to any reasonably necessary transition assistance reasonably requested by
Spinco in good faith. 
 ARTICLE 3 

COMPENSATION 

3.1    Services Fees. In consideration for the performance of the Services by AZ, Spinco shall pay the applicable
fees therefor set forth on Schedule 2.1 (the “Services Fees”); provided, that if the Parties mutually agree that the Service Period for any Service should be extended beyond the Service Period stated in
Schedule 2.1, the Service Fee for such Service shall be increased to equal (a) [***] of the applicable Service Fee stated in Schedule 2.1 for the initial extension of such Service Period and (b) [***] of the applicable Service Fee stated in
Schedule 2.1 for a second extension of such Service Period. In addition, Spinco shall reimburse AZ for any Out-of-Pocket Costs, not to exceed [***] per single expense
without Spinco’s prior approval (such approval not to be unreasonably withheld, conditioned or delayed and with respect to Out-of-Pocket Costs exceeding [***] per
single expense, upon receipt of applicable receipts and other reasonable supporting documentation). Notwithstanding the foregoing, upon Spinco’s reasonable request from time to time, AZ shall provide reasonable supporting documentation of its Out-of-Pocket Costs less than [***] but exceeding [***] per single expense if Spinco reasonably determines in good faith that such documentation is necessary for its bona fide
accounting purposes. 
 3.2    Invoicing. AZ shall, on a calendar monthly basis, invoice Spinco for applicable
Services Fees and Out-of-Pocket Costs. [***]. 

3.3    Due Date. Spinco shall pay each invoice for Services Fees and Out-of-Pocket Costs promptly, but in no event later than [***] [***], after the date of receipt of such invoice. Any payments under this Agreement that are not made on or before the applicable due date shall
bear [***], as reported in the print edition of The Wall Street Journal, Eastern Edition, on the date such payment was due or, if unavailable, on the latest date prior to the payment due date on which such rate is available, and (b) [***]

 3.4    Taxes. 

3.4.1    The amounts payable by Spinco to AZ pursuant to this Agreement (“Payments”) shall not be reduced
on account of any Taxes unless required by applicable Law. AZ alone shall be responsible for paying any and all Taxes (other than withholding Taxes required to be paid by Spinco) levied on account of, or measured in whole or in part by reference to,
any Payments it receives. Spinco shall deduct or withhold from the Payments any Taxes that it is required by applicable Law to deduct or withhold. To the extent that any such Tax is deducted or withheld, such amount shall be treated for all purposes
of the Agreement as having been paid to the Person in respect of which such deduction or withholding was made. Notwithstanding the foregoing, if AZ is entitled under any applicable Tax treaty to a reduction of rate of, or the elimination of, or
recovery of, applicable withholding Tax, it shall deliver to 

  
 -7- 

[*] = CERTAIN CONFIDENTIAL INFORMATION CONTAINED IN THIS DOCUMENT, MARKED BY BRACKETS, HAS BEEN OMITTED BECAUSE THE INFORMATION (I) IS NOT MATERIAL AND
(II) WOULD BE COMPETITIVELY HARMFUL IF PUBLICLY DISCLOSED 













 
Spinco or the appropriate Governmental Authority (with the assistance of Spinco to the extent that this is reasonably required and is expressly requested in writing) the prescribed forms
necessary to reduce the applicable rate of withholding or to relieve Spinco of its obligation to withhold Tax, and Spinco shall apply the reduced rate of withholding, or dispense with the withholding, as the case may be, to the extent it complies
with the applicable Tax treaty. If, in accordance with the foregoing, Spinco withholds any amount, it shall make timely payment to the proper Taxing Authority of the withheld amount, and send to AZ proof of such payment within 60 days following that
payment. 
 3.4.2    All Payments are stated exclusive of Indirect Taxes. If any Indirect Taxes are chargeable in
respect of any Payments, Spinco shall pay such Indirect Taxes at the applicable rate in respect of any such Payments following the receipt, where applicable, of an Indirect Taxes invoice in the appropriate form issued by AZ in respect of such
Payments, such Indirect Taxes to be payable on the due date of the payment of the Payments to which such Indirect Taxes relate. AZ shall issue its invoices for all amounts payable under this Agreement consistent with Indirect Tax requirements and
irrespective of whether the sums may be netted for settlement purposes. 
 3.5    Records; Audit. 

3.5.1    AZ shall keep and maintain, and shall cause its Affiliates to keep and maintain, complete and accurate records and
books of account documenting all expenses and all other data necessary for the calculation of the amounts payable by Spinco under this Agreement consistent with its standard procedures and policies in the ordinary course of business for a period of
two years after such expenses are incurred, unless a longer retention period is required by applicable Law. 

3.5.2    Upon Spinco’s request, AZ shall, and shall cause each of its Affiliates engaged in the performance of
activities under this Agreement to, permit Spinco and its Representatives to inspect and audit the records and books of account maintained by it pursuant to Section 3.5.1 in order to confirm the accuracy and completeness of such records and
books of account and all payments hereunder; provided, that Spinco shall not be entitled to exercise its inspection and audit rights under this Section 3.5.2 more than once per Calendar Year, unless, in any case, any prior audit resulted
in an adjustment to amounts due hereunder. Spinco shall bear all out-of-pocket costs and expenses incurred in connection with any inspection or audit performed pursuant
to this Section 3.5.2; provided, however, that AZ shall reimburse Spinco for all reasonable costs and expenses incurred by Spinco in connection with such inspection or audit if any such audit identifies an overpayment to AZ hereunder in
excess of [***] of the amount subject to the audit. In any case, the full amount of any overpayment or underpayment as applicable shall be payable to the applicable Party plus accrued interest at a rate equal to the lesser of (a) [***] above the
Prime Rate, as reported in the print edition of The Wall Street Journal, Eastern Edition, on the date such payment was due or, if unavailable, on the latest date prior to the payment due date on which such rate is available, and (b) [***].
All information disclosed pursuant to this Section 3.5.2 shall be subject to the non-disclosure and non-use provisions set forth in Article 5.

THE OTHER OR THEIR AFFILIATES, FOR ANY CLAIMS, DEMANDS OR SUITS FOR CONSEQUENTIAL, INCIDENTAL, SPECIAL, EXEMPLARY, PUNITIVE, INDIRECT OR MULTIPLE DAMAGES, FOR LOSS OF PROFITS, REVENUE OR INCOME, DIMINUTION IN VALUE OR LOSS OF BUSINESS OPPORTUNITY

Agreement shall be pursuant to the indemnification provisions set forth in this Article 6. 
 ARTICLE 7 

TERM AND TERMINATION 

7.1    Term. This Agreement shall commence on the Effective Date and shall continue in full force and effect until
the earliest of (a) the date on which this Agreement is terminated in accordance with this Article 7; (b) the expiration of the last Service Period, such that AZ is no longer obligated to provide any Services pursuant to this Agreement; and
(c) the termination by Spinco of the only remaining outstanding Services pursuant to Section 7.2.1, such that AZ is no longer obligated to provide any Services pursuant to this Agreement (the “Transition Period”). For
purposes of this Agreement, the term “Service Period” shall mean, with respect to any particular Service, the period between the Effective Date and the termination date for the transition period as set forth in
Schedule 2.1 with respect to such Service. For clarity, all obligations of AZ to provide to Spinco any Services under this Agreement shall cease at the end of the Transition Period. 

7.2    Termination of Services. 

7.2.1    Spinco may, at any time prior to the end of the Transition Period and upon 30 days’ (or such longer period,
if any, specified in Schedule 2.1 for a particular Service) prior written notice to AZ, terminate this Agreement in its entirety or with respect to all or any Services, whereupon, from and after the date of termination specified in such
written notice, AZ’s obligation to provide such Services to Spinco shall cease and Spinco shall have no obligation to pay AZ for such Service(s) (other than with respect to those Services requested by Spinco, and performed by AZ or its
Affiliates or subcontractors, and costs incurred, or non-cancellable commitments made, prior to termination); provided that if termination of any Service materially inhibits AZ’s ability to provide
or prevents AZ from providing any other Services (as determined in AZ’s sole discretion), such other Services shall also shall be deemed terminated (provided, that AZ first notifies Spinco in writing of the Services that AZ would be
materially inhibited or prevented from providing due to such termination, and Spinco does not revoke such termination within [***] of receiving such notice from AZ).

 7.2.2    In the event that either Party (the “Breaching
Party”) breaches any of its material obligations under this Agreement, the other Party may terminate this Agreement upon 30 days’ prior written notice (such 30-day period, the “Notice
Period”) to the Breaching Party, specifying the breach and its claim of right to terminate; provided, that the termination of this Agreement shall not become effective at the end of the Notice Period if (a) the Breaching Party
cures such breach during the Notice Period or (b) such breach cannot be cured during the Notice Period and the Breaching Party commences and diligently pursues actions to cure such breach within the Notice Period, in which case the Breaching
Party shall have an additional 30-day period to cure such breach before such termination shall become effective, provided, further, that a [***] cure period shall apply to any breach of a payment
obligation hereunder and such cure period shall not be subject to extension in accordance with the preceding proviso. 

7.2.3    Either Party may terminate this Agreement immediately upon written notice to the other Party if the other Party
(a) files in any court or with any other Governmental Authority, pursuant to any Law of any state or country, a petition in bankruptcy or insolvency or for reorganization or for an arrangement or for the appointment of a receiver or trustee of
that Party or of its assets; (b) proposes a written agreement of composition or extension of its debts; (c) is served with an involuntary petition against it, filed in any insolvency proceeding, and such petition is not dismissed within
[***] [***] after the filing thereof; (d) consents to the appointment or taking possession by a receiver, liquidator, assignee, custodian, trustee, sequestrator (or similar official) of such Party or for any substantial part of its property or
makes any assignment for the benefit of creditors; (e) admits in writing its inability to pay its debts generally as they become due; or (f) has issued or levied against its property any judgment, writ, warrant of attachment or execution
or similar process that represents a substantial portion of its property. 
 7.2.4    Either Party may terminate this
Agreement to the extent provided in Section 8.1. 
 7.2.5    This Agreement may be terminated upon the mutual
written agreement of Spinco and AZ at any time. 
 7.3    Accrued Rights; Surviving Obligations. 

7.3.1    Accrued Rights. Termination or expiration of this Agreement for any reason shall be without prejudice to
any rights that shall have accrued to the benefit of a Party prior to such termination or expiration. Such termination or expiration shall not relieve a Party from obligations that are expressly indicated to survive the termination or expiration of
this Agreement. 
 7.3.2    Surviving Obligations. Without limiting the foregoing, [***] shall survive the
termination or expiration of this Agreement for any reason.

 ARTICLE 8 

MISCELLANEOUS 

8.1    Force Majeure. Except for the obligation to pay amounts due and owing, neither Party shall be liable for any
failure to perform or any delays in performance, and no such Party shall be deemed to be in breach or default of its obligations set forth in this Agreement, if, to the extent and for so long as, such failure or delay is due to any causes that are
beyond its reasonable control and without its fault or negligence, including such causes as acts of God, natural disasters, fire, flood, severe storm, earthquake, civil disturbance, lockout, riot, order of any court or administrative body, embargo,
acts of government, war (whether or not declared), acts of terrorism, or other similar causes (“Force Majeure Event”). In the event of a Force Majeure Event, the Party prevented from or delayed in performing shall
promptly give notice to the other Party and shall use commercially reasonable efforts to avoid or minimize the delay. In the event that the delay continues for a period of at least 30 days, the Party affected by the other Party’s delay may
elect to (a) suspend performance and extend the time for performance for the duration of the Force Majeure Event, or (b) terminate this Agreement without any liability to either Party arising out of such termination. 

8.2    Independent Contractor. The Parties and each of their respective Affiliates shall each be an independent

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 in connection with any litigation arising out of or relating to this
Agreement or the transactions contemplated hereby. 
 8.3.3    Venue. 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

 8.5    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 any indemnified Person under Article 6, they shall not be construed as conferring any rights on any other Persons. 

8.6    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. 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. 

8.7    Assignment. 

8.7.1    Subject to the remainder of this Section 8.7, neither this Agreement nor either Party’s rights or
obligations hereunder may be assigned or delegated by such Party, directly or indirectly (by operation of Law or otherwise), without the prior written consent of the other Party; provided, however, that (a) AZ may assign or
delegate any or all of its rights or obligations hereunder to an Affiliate of AZ or to any successor in interest (whether by merger, acquisition, asset purchase or otherwise) to all or substantially all of the business to which this Agreement
relates, and may delegate any or all of its obligations hereunder to subcontractors, in each case, without the prior written consent of Spinco and (b) Spinco may assign its rights, interests, and obligations hereunder (in whole and not in part)
to a wholly owned Affiliate of Spinco without AZ’s prior written approval. 
 8.7.2    Following the earlier to
occur of (a) the consummation in full of the Milestone Closing (as defined in the Securities Purchase Agreement), and (b) the consummation of a Qualified IPO (as defined in the Restated Certificate (as defined in the Securities Purchase
Agreement)), Spinco may assign its applicable rights, interests, and obligations hereunder related to one or more Programs to a Third Party without AZ’s prior written approval, so long as (i) such assignment shall be in connection with the
divestment by Spinco of all or substantially all of the assets relating to such Program or Programs (whether by asset purchase or exclusive out-license), (ii) in connection therewith, Spinco also assigns to
such Third Party its applicable rights, interests, and obligations under the other Transaction Agreements related to such Program or Programs, and (iii) proper provision shall be made so that the successors and assigns of Spinco shall succeed
to Spinco’s applicable rights and obligations set forth herein and therein.

 8.7.3    If Spinco or any of its successors or assigns
(a) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (b) transfers, licenses or conveys all or substantially all of its rights and
assets to any Person, then, and in each such case, Spinco may assign its rights, interests and obligations hereunder (in whole and not in part) to such Person without the prior written approval of AZ so long as in connection therewith Spinco
(i) also assigns to such Person all of its applicable rights, interests, and obligations under the other Transaction Agreements, and (ii) ensures that proper provision shall be made so that the successors and assigns of Spinco shall
succeed to Spinco’s rights and obligations set forth in this Agreement. 
 8.7.4    Notwithstanding anything to the
contrary set forth herein, no assignment or succession pursuant to this Section 8.7 shall relieve the assigning Party or predecessor Party of its obligations hereunder. Upon any permitted assignment, the references in this Agreement to a Party
shall also apply to any such assignee unless the context otherwise requires. 
 8.7.5    Subject to the remainder of
this Section 8.7, this Agreement shall be binding upon, inure to the benefit of, and be enforceable by, the Parties and their respective successors and permitted assigns. Any attempted assignment or transfer in violation of this
Section 8.7 shall be null and void. 
 8.7.6    Notwithstanding the foregoing, in the event a Party assigns its
rights or obligations under this Agreement or otherwise makes payments from a jurisdiction other than the jurisdiction in which such Party is organized (each, an “Assignment”), and immediately after such Assignment the amount of Tax
required to be withheld on any payment pursuant to this Agreement is greater than the amount of such Tax that would have been required to have been withheld absent such Assignment, then such increased withholding tax shall be borne by the Party
making such Assignment. 
 8.8    Amendment. Except as expressly provided herein, this Agreement may not be
modified, amended, altered or supplemented except upon the execution and delivery of a written agreement executed by both Parties. 

8.9    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. 

8.10    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.

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
