Agent shall have no liability to the Escrow Issuer, the Trustee or any other person or entity as a consequence of performance or non-performance by the Escrow Agent hereunder, except for any bad faith, gross
negligence or willful misconduct by the Escrow Agent that was the cause of any direct loss to either Party; (iii) the Escrow Issuer shall remain solely responsible for all aspects of the Escrow Issuer’s business and conduct; and
(iv) the Escrow Agent shall not be obligated to supervise, inspect or inform the Escrow Issuer or any third party of any matter referred to above. In no event shall the Escrow Agent be liable (i) for relying upon any judicial or
administrative order or judgment, upon any opinion of counsel or upon any certification, instruction, notice or other writing delivered to it by the Escrow Issuer or the Trustee in compliance with the provisions of this Agreement, (ii) for
acting in accordance with or relying upon any 

  
 -11- 

 
instruction, notice, demand, Entitlement Order, certificate or document believed by it in good faith to be genuine and to have been signed by an Authorized Representative of a specified Party,
(iii) for any special, incidental, indirect, consequential, or punitive damages or losses of any kind whatsoever (including, but not limited to, lost profits), even if the Escrow Agent has been advised of the likelihood of such loss or damage
and regardless of the form of action, (iv) for the acts or omissions of its nominees, correspondents, designees, subagents or sub-custodians appointed with due care or (v) for an amount in excess of
the value of the Senior Secured Escrowed Property, valued as of the date hereof, plus, if applicable, each Additional Interest Deposit. Except as specifically provided herein, the Escrow Agent shall have no duty to solicit any payments which may be
due it or the Escrow Accounts, including, without limitation, the Senior Secured Escrowed Property, nor shall the Escrow Agent have any duty or obligation to confirm or verify the accuracy or correctness of any amounts deposited with it
hereunder. 
 The Escrow Agent undertakes to perform only such duties as are expressly set forth herein, which shall be deemed purely
ministerial in nature and no duties, including, but not limited to, any fiduciary duty, shall be implied. The Escrow Agent shall have no liability under and no duty to inquire as to the provisions of any agreement other than this Agreement,
including, without limitation, the Indenture or any other agreement between any or all of the parties hereto or any other persons even though reference thereto may be made herein, nor shall the Escrow Agent be required to determine if any Party has
complied with any other agreement. Notwithstanding the terms of any other agreement between the Parties, the terms and conditions of this Agreement shall control the actions of the Escrow Agent. The Escrow Agent shall not be charged with knowledge
or notice of any fact or circumstance not specifically set forth herein. The Escrow Agent may rely upon any notice, instruction, request or other instrument, not only as to its due execution, validity and effectiveness, but also as to the truth and
accuracy of any information contained therein, which the Escrow Agent shall in good faith believe to be genuine and to have been signed by an Authorized Representative or presented by the Escrow Issuer and/or Trustee purporting to sign the same. Any
notice, document, instruction or request delivered by a Party but not required under this Agreement may be disregarded by the Escrow Agent and returned to the sending Party. The rights and powers granted to the Escrow Agent hereunder are being
granted in order to preserve and protect the Trustee’s security interest in and to the Collateral granted hereby and shall not be interpreted to, and shall not, impose any duties on the Escrow Agent in connection therewith other than those
imposed under applicable law. The Escrow Agent shall exercise the same degree of care in the custody and preservation of the Collateral in its possession as it exercises toward its own similar property and shall not be held to any higher standard of
care under this Agreement, nor be deemed to owe any fiduciary duty to the Escrow Issuer, the Trustee or any other party. 
 At the expense
of the Escrow Issuer, the Escrow Agent may act pursuant to the advice of counsel chosen by it with respect to any matter relating to this Agreement and shall not be liable for any action taken or omitted in accordance with such advice, except for
any such action taken or omitted in bad faith. 
 In the event of any ambiguity in the provisions of this Agreement with respect to any
Senior Secured Escrowed Property, or instruction, notice or certification delivered hereunder, the Escrow Agent shall be entitled to refuse to comply with any and all claims, demands or instructions with respect to such Senior Secured Escrowed
Property and the Escrow Agent shall not be or become liable for its failure or refusal to comply with conflicting claims, demands or instructions. The Escrow Agent shall be entitled to refuse to act until either (i) it shall have received an
instruction from an Authorized Representative of the Trustee and an Authorized Representative of the Escrow Issuer or (ii) any conflicting or adverse claims or demands shall have been finally determined by a court of competent jurisdiction or
settled by agreement between the conflicting claimants as evidenced in a writing reasonably satisfactory to the Escrow Agent (which such decision shall be binding on all parties hereto). 

  
 -12- 

 No provision of this Agreement shall require the Escrow Agent to expend or risk its own
funds or otherwise incur any financial liability in the performance of any of its duties hereunder. 
 The Escrow Agent shall not incur any
liability for not performing any act or fulfilling any duty, obligation or responsibility hereunder by reason of any occurrence beyond the control of the Escrow Agent (including, but not limited to, any act or provision of any present or future law
or regulation or governmental authority, any act of God, terrorism or war, the failure or malfunction of communication or computer systems, or the unavailability of the Federal Reserve Bank wire or telex or other wire or communication facility).

 5.      Indemnity. The Escrow Issuer shall indemnify, hold harmless, pay or reimburse and defend
the Escrow Agent and its directors, officers, agents, employees and controlling persons, affiliates and their respective successors and assigns (each, an “Indemnified Person”) from and against any and all losses, penalties,
judgments, settlements, litigation, claims, actions, obligations, liabilities and expenses, including reasonable and documented defense costs, reasonable and documented investigative fees and costs, reasonable and documented legal fees (limited to
one outside counsel and one counsel in each relevant jurisdiction) and claims for damages, arising out of or in connection with (a) the Escrow Agent’s performance or non-performance, or in connection
with the Escrow Agent’s acceptance of appointment as the Escrow Agent under this Agreement, except to the extent that such liability, expense or claim is solely and directly attributable to the bad faith, gross negligence or willful misconduct
of any such Indemnified Person (as determined by a judgment of a court of competent jurisdiction) and (b) the Escrow Agent’s following, accepting or acting upon any instructions or directions, whether joint or singular, from the Escrow
Issuer and/or Trustee received in accordance with this Agreement. The provisions of this Section 5 shall survive any termination, satisfaction or discharge of this Agreement as well as the resignation or removal of the Escrow Agent. 

6.      Grant of Security Interest; Instructions to Escrow Agent. 

(a)      The Escrow Issuer hereby grants a first-priority security interest in and lien on, and pledges to the Trustee
for the benefit of the Secured Parties, all of its right, title and interest in, to the extent applicable, (i) the Escrow Accounts, the Senior Secured Escrowed Property now or hereafter placed or deposited in, or delivered to the Escrow Agent
for placement or deposit in, the Escrow Accounts, including, without limitation, all funds and Financial Assets held therein, and the MMDA held by (or otherwise maintained in the name of) the Escrow Agent pursuant to Section 2 and (ii) all
proceeds (as such term is defined in Section 9-102(a) of the UCC or the PPSA, as applicable) of any of the foregoing (collectively, the “Collateral”), in order to secure the Escrow
Issuer’s obligations under the Notes and the Indenture. The Escrow Agent hereby acknowledges the Trustee’s security interest and lien as set forth above. The Escrow Issuer shall take all actions necessary on its part to provide for the
continuance of a perfected first-priority security interest in the Collateral in favor of the Trustee in order to secure all Notes. The Escrow Issuer shall not grant or cause or permit any other person to obtain a security interest, encumbrance,
lien or other claim, direct or indirect, in the Escrow Issuer’s right, title or interest in the Escrow Accounts or any Collateral (other than any such liens or claims imposed by applicable law and the Escrow Agent’s rights in and to the
Escrow Accounts and the Collateral therein). It is understood that Escrow Agent has no responsibility with respect to the validity or perfection of the security interest other than to act in accordance with the terms of this Agreement. 

(b)      The Escrow Issuer and the Trustee hereby irrevocably instruct the Escrow Agent to, and the Escrow Agent
shall: 
 (i)      maintain the Escrow Accounts for the sole and exclusive benefit of the Trustee on
its own behalf and on behalf of the Secured Parties to the extent specifically required herein; 

  
 -13- 

 (ii)      as promptly as practicable notify the
Trustee if the Escrow Agent receives written notice that any person other than the Trustee has or purports to have a lien or security interest upon any portion of the Collateral; and 

(iii)     transfer the Collateral to the Trustee and/or Escrow Issuer (or as directed by the Trustee and/or
the Escrow Issuer) to the extent required by Section 3(b), Section 3(c), Section 3(d) or Section 3(e). 
 The lien and
security interest provided for in this Section 6 shall automatically terminate and cease as to, and shall not extend or apply to, and the Trustee shall have no security interest in, any funds disbursed by the Escrow Agent to the Escrow Issuer
pursuant to Section 3(b), Section 3(c), Section 3(d) or Section 3(e). The Escrow Agent shall not have any right to receive compensation from the Trustee and shall have no authority to obligate the Trustee or to compromise or
pledge its security interest hereunder. Accordingly, the Escrow Agent is hereby directed to cooperate with the Trustee in the exercise of its rights in the Collateral provided for herein. 

(c)      The Escrow Issuer will execute and deliver or cause to be executed and delivered, or use its reasonable best
efforts to procure, all assignments, instruments and other documents, deliver any instruments to the Trustee and take any other actions that are necessary or desirable to perfect, continue the perfection of, or protect the first priority of the
Trustee’s security interest in and to the Collateral, to protect the Collateral against the rights, claims or interests of third persons or to effect the purposes of this Agreement, file or to cause to be filed one or more UCC or PPSA financing
statements, financing change statements and continuation statements in such jurisdictions and filing offices and containing such description of collateral as are reasonably necessary or advisable in order to perfect the security interest granted
herein. The Escrow Issuer shall pay (or cause to be paid) all reasonable and documented out-of-pocket costs incurred in connection with any of the foregoing, it being
understood that the Trustee shall have no duty to determine whether to file or record any document or instrument relating to Collateral. Neither the Trustee nor the Escrow Agent shall have any duty or obligation to file or record any document or
otherwise to see to the grant or perfection of any security interest granted hereunder. 
 (d)      The Escrow
Issuer hereby appoints the Trustee as attorney-in-fact with full power of substitution to do any act that the Escrow Issuer is obligated under this Section 6 to do,
and the Trustee may, but shall not be obligated to, upon the occurrence and during the continuation of an Event of Default, exercise under this Section 6 such rights as the Escrow Issuer might exercise with respect to the Collateral and take
any action in the Escrow Issuer’s name to protect the Trustee’s security interest hereunder.     
 (e)
     The Escrow Agent represents that the Escrow Agent is a “depository bank” and that the Cash Account is a “deposit account” and the Escrow Agent is a “securities intermediary” only for the
Securities Account which is a “securities account” (as each such term is defined in the UCC). Subject to the terms of this Agreement, the Escrow Accounts shall be under the exclusive control of the Trustee. If at any time Escrow Agent
shall receive any instructions or Entitlement Orders from the Trustee directing the disposition of funds or financial assets in the Escrow Accounts (including the MMDA) or otherwise related to the Escrow Accounts, the Escrow Agent shall comply with
any such instructions or Entitlement Orders without further consent by the Escrow Issuer or any other person and, except as provided herein, Escrow Issuer shall not have any right to give instructions related to the Escrow Accounts to Escrow Agent.
The Trustee agrees that it shall not issue any such instruction or Entitlement Order except as permitted by the terms of this Agreement and the Indenture. The Escrow Issuer represents that its legal name is that set forth on the signature pages
hereof and it is validly existing as a corporation organized under the laws of Ontario and is not organized under the laws of any other jurisdiction. During the term of this Agreement, the Escrow Issuer will not change its legal name, identity or
organizational type, jurisdiction of organization or location of the chief executive office without giving the Trustee and Escrow Agent prompt written notice and within thirty (30) days it shall have taken all actions reasonably necessary to
maintain the perfection and priority of the security interest granted hereunder, if applicable. 

  
 -14- 

 (f)      The Escrow Issuer hereby confirms that the security
interest granted pursuant to this Agreement has been validly created and arrangements established under this Section 6 constitute “control” (within the meanings of the PPSA and Sections 9-104
and 9-106 of the UCC) by the Trustee of the Escrow Accounts and the Senior Secured Escrowed Property credited thereto. The Escrow Agent and the Escrow Issuer have not entered and will not enter into any other
agreement with respect to control of the Escrow Accounts or purporting to limit or condition the obligation of the Escrow Agent to comply with any orders or instructions of the Trustee with respect to the Escrow Accounts as set forth in this
Section 6. In the event of any conflict with respect to control over the Escrow Accounts between this Agreement (or any portion hereof) and any other agreement now existing or hereafter entered into, the terms of this Agreement shall prevail.

 (g)      The Escrow Agent hereby agrees that any security interest in, lien on, encumbrance, claim or right of
setoff against, the Escrow Accounts or any funds or Financial Assets therein or credited thereto that it now has or subsequently obtains shall be subordinate to the security interest of the Trustee in the Escrow Accounts and the funds or Financial
Assets therein or credited thereto. The Escrow Agent agrees not to exercise any present or future right of recoupment or set-off against the Escrow Accounts or to assert against the Escrow Accounts any present
or future security interest, banker’s lien or any other lien or claim (including claim for penalties) that the Escrow Agent may at any time have against or in the Escrow Accounts or any funds or Financial Assets therein or credited thereto. The
Escrow Agent hereby agrees that it shall not change the name or account number of any of the Escrow Accounts without the prior written consent of the Trustee. 

(h)      As solely between the Escrow Issuer and Trustee, the Escrow Issuer confirms that value has been given by the
Secured Parties to the Escrow Issuer, that the Escrow Issuer has rights in its Collateral existing at the date of this Agreement, and that the Escrow Issuer and the Trustee have not agreed to postpone the time for attachment of the security
interests to any of the Collateral of the Escrow Issuer. As solely between the Escrow Issuer and Trustee, the security interests with respect to the Collateral of the Escrow Issuer created by this Agreement shall have effect and be deemed to be
effective whether or not the Escrow Issuer’s obligations under the Notes and the Indenture or any part thereof are owing or in existence before or after or upon the date of this Agreement. As solely between the Escrow Issuer and Trustee,
neither the execution and delivery of this Agreement nor the provision of any financial accommodation by any Secured Party shall oblige any Secured Party to make any financial accommodation or further financial accommodation available to the Escrow
Issuer or any other Person. 
 7.      Termination; Survival. This Agreement and the security
interest in the Senior Secured Escrowed Property evidenced by this Agreement shall terminate automatically and be of no further force or effect and the Escrow Accounts shall be closed upon the distribution of all Senior Secured Escrowed Property in
accordance with Section 3 hereof; provided, however, that the obligations of the Escrow Issuer under Section 2(b) and Section 5 (and any existing claims thereunder) shall survive termination of this Agreement and the
resignation or removal of the Escrow Agent. All representations, warranties and covenants of the Escrow Issuer contained herein shall survive the execution and delivery of this Agreement, and shall terminate only upon the termination of this
Agreement. 
 8.      Security Interest Absolute. All rights of the Trustee for its own benefit and
the benefit of the holders of the Notes and security interests hereunder, and all obligations of the Escrow Issuer hereunder, shall be absolute and unconditional irrespective of: 

(a)      any lack of validity or enforceability of the Indenture or any other agreement or instrument
relating thereto; 

  
 -15- 

 (b)      any change in the time, manner or place of
payment of, or in any other term of, all or any of the obligations under the Notes and the Indenture, or any other amendment or waiver of or any consent to any departure from the Indenture; 

(c)      any exchange, surrender, release or non-perfection of
any Liens on any other collateral for all or any of the obligations under the Notes and the Indenture; or 
 (d)
     to the extent permitted by applicable law, any other circumstance which might otherwise constitute a defense available to, or a discharge of, the Escrow Issuer in respect of the Notes and the Indenture or of this
Agreement. 
  

	 	9.	 Miscellaneous. 

(a)      Waiver. Any party hereto may specifically waive any breach of this Agreement by any other party, but
no such waiver shall be deemed to have been given unless such waiver is in writing, signed by the waiving party and specifically designating the breach waived, nor shall any such waiver constitute a continuing waiver of similar or other breaches.

 (b)      Invalidity. If for any reason whatsoever any one or more of the provisions of this Agreement
shall be held or deemed to be inoperative, unenforceable or invalid in a particular case or in all cases, such circumstances shall not have the effect of rendering any of the other provisions of this Agreement inoperative, unenforceable or invalid,
and the inoperative, unenforceable or invalid provision shall be construed as if it were written so as to effectuate, to the maximum extent possible, the Parties’ intent. 

(c)      Assignment. This Agreement is personal to the parties hereto, and the rights and duties of the Escrow
Issuer hereunder shall not be assignable except with the prior written consent of the Trustee and Escrow Agent and any assignment in violation of this Agreement shall be ineffective and void. Similarly, the rights and duties of the Trustee hereunder
shall not be assignable except with the prior written consent of the Escrow Issuer and Escrow Agent and except to a successor trustee in accordance with the Indenture. Notwithstanding the foregoing, this Agreement shall inure to and be binding upon
the parties and their successors and permitted assigns. Any entity into which Escrow Agent may be merged or converted or with which it may be consolidated, or any entity to which all or substantially all the escrow business may be transferred, shall
be the Escrow Agent under this Agreement without further act or consent of the Parties. 
 (d)      Benefit.
This Agreement shall be binding upon the parties hereto and their successors and permitted assigns. Nothing in this Agreement, express or implied, shall give to any person, other than the Parties hereto and their successors hereunder any benefit or
any legal or equitable right, remedy or claim under this Agreement. 
 (e)      Entire Agreement;
Amendments. This Agreement and the Indenture contain the entire agreement among the Parties with respect to the subject matter hereof and supersede any and all prior agreements, understandings and commitments, whether oral or written. The
provisions of this Agreement may be waived, altered, amended or supplemented only by a writing signed by Escrow Agent, Trustee and Escrow Issuer. As solely between the Escrow Issuer and Trustee, no provisions of this Agreement (including, without
limitation, those relating to the release of the Senior Secured Escrowed Property) may be waived or modified in any manner materially adverse to the holders of the Notes (as determined in good 

  
 -16- 

 
faith by the Escrow Issuer) without the written consent of the holders of a majority in principal amount of the Notes outstanding and must otherwise be amended in accordance with the terms of the
Indenture. Neither the Escrow Agent nor the Trustee shall be deemed, by any act, delay, indulgence, omission or otherwise, to have waived any right or remedy hereunder or to have acquiesced in any Default or Event of Default or in any breach of any
of the terms and conditions hereof. No single or partial exercise of any right, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege. A waiver by the Escrow Agent or
the Trustee of any right or remedy hereunder on any one occasion shall not be construed as a bar to any right or remedy that the Escrow Agent or the Trustee would otherwise have on any future occasion. The rights and remedies herein provided are
cumulative, may be exercised singly or concurrently and are not exclusive of any rights or remedies provided by law. 
 (f)
     Notices. Except as otherwise required by Section 3(f) above, all notices and other communications required or permitted to be given or made under this Agreement shall be in writing and shall be deemed to have been

(g)      Counterparts. This Agreement and any joint instructions may be executed in one or more counterparts
and, if executed in more than one counterpart, the executed counterparts shall each be deemed to be an original but all such counterparts shall together constitute one and the same instrument. Delivery of an executed counterpart of a signature page

“delivery,” and words of like import in this Agreement shall be deemed to include electronic signatures or electronic records, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature,
physical delivery thereof or the use of a paper-based recordkeeping system, as the case may be. 
 (h)     
Captions. Captions in this Agreement are for convenience only and shall not be considered or referred to in resolving questions of interpretation of this Agreement.

EFFECT OF ANY AND ALL TERMS AND PROVISIONS OF THIS AGREEMENT AND THE ESCROW ACCOUNTS, INCLUDING THE ISSUES SPECIFIED IN ARTICLE 2 OF THE HAGUE CONVENTION ON THE LAW APPLICABLE TO CERTAIN RIGHTS IN RESPECT OF SECURITIES HELD WITH AN INTERMEDIARY (THE
“HAGUE SECURITIES CONVENTION”) SHALL BE DETERMINED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK. THE PARTIES TO THIS AGREEMENT HEREBY AGREE THAT JURISDICTION OVER SUCH PARTIES AND OVER THE SUBJECT MATTER OF ANY
ACTION OR PROCEEDING ARISING UNDER THIS AGREEMENT MAY BE EXERCISED BY A COMPETENT COURT OF THE CITY AND STATE OF NEW YORK, OR BY A COMPETENT UNITED STATES COURT, SITTING IN NEW YORK CITY. THE ESCROW ISSUER, THE TRUSTEE AND THE ESCROW AGENT HEREBY
SUBMIT TO THE PERSONAL JURISDICTION OF SUCH COURTS. FOR PURPOSES OF THE UCC, THE ESCROW AGENT’S JURISDICTION (WITHIN THE MEANING OF SECTIONS 9-305 AND 8-110 OF THE
UCC) AND ARTICLE 2(1) OF THE HAGUE SECURITIES CONVENTION SHALL BE THE STATE OF NEW YORK. EACH OF THE PARTIES HERETO WAIVES THE RIGHT TO A TRIAL BY JURY AND TO ASSERT COUNTERCLAIMS OTHER THAN MANDATORY COUNTERCLAIMS IN ANY ACTION OR PROCEEDING
RELATING TO OR ARISING FROM, DIRECTLY OR INDIRECTLY, THIS AGREEMENT. EACH OF THE

ESCROW ISSUER, TRUSTEE AND ESCROW AGENT HEREBY WAIVES PERSONAL SERVICE OF PROCESS AND CONSENTS TO SERVICE OF PROCESS BY CERTIFIED OR REGISTERED MAIL, RETURN RECEIPT REQUESTED, DIRECTED TO IT AT
THE ADDRESS LAST SPECIFIED FOR NOTICES HEREUNDER, AND SUCH SERVICE SHALL BE DEEMED COMPLETED TEN (10) CALENDAR DAYS AFTER THE SAME IS SO MAILED. 

(j)      Representations and Warranties of the Escrow Issuer. The Escrow Issuer hereby represents and warrants
that this Agreement has been duly authorized, executed and delivered on its behalf and constitutes its legal, valid and binding obligation, enforceable in accordance with its terms (except as the enforcement thereof may be limited by bankruptcy,
reorganization, insolvency (including, without limitation, all laws relating to fraudulent transfers), moratorium or other laws relating to or affecting creditors’ rights and remedies generally and except as the enforcement thereof is subject
to equitable principles regardless of whether enforcement is considered in a proceeding at law or in equity). The execution, delivery and performance of this Agreement by the Escrow Issuer does not violate any material applicable law or regulation
to which the Escrow Issuer is subject and does not require the consent of any governmental or other regulatory body to which the Escrow Issuer is subject, except for such consents and approvals as have been obtained and are in full force and effect.
The Escrow Issuer is, with respect to the Collateral it is delivering pursuant to this Agreement, the beneficial owner of such Collateral, free and clear of any Lien or claims of any person (except for the security interest granted under this
Agreement and the Indenture and the rights of the Escrow Agent to the Escrow Accounts and the Senior Secured Escrowed Property therein) and is the only owner of the Escrow Accounts and funds deposited therein. The person(s) executing this Agreement
on behalf of the Escrow Issuer and certifying Authorized Representatives in Schedule I-A have been duly and properly authorized to do so, and each Authorized Representative of the Escrow Issuer has been
duly and properly authorized to take the actions specified for such person in Schedule I-A. 

(k)      Representations and Warranties of Escrow Agent and Trustee. The Escrow Agent hereby represents and
warrants that this Agreement has been duly authorized, executed and delivered on its behalf and constitutes its legal, valid and binding obligation enforceable in accordance with its terms. The Trustee hereby represents and warrants that the
person(s) executing this Agreement and certifying Authorized Representatives in Schedule I-B is duly authorized to do so, and that this Agreement has been duly executed and delivered on its behalf and
each Authorized Representative of the Trustee has been duly and properly authorized to take the actions specified for such person in Schedule I-B. 

(l)      Reserved. 

(m)      Interpretation of Agreement. All terms not defined herein or in the Indenture shall have the meaning
set forth in the UCC or the PPSA, as applicable, except where the context otherwise requires. To the extent a term or provision of this Agreement relating to the Trustee or the Escrow Issuer conflicts with the Indenture, the Indenture shall control
with respect to the subject matter of such term or provision. Acceptance of or acquiescence in a course of performance rendered under this Agreement shall not be relevant to determine the meaning of this Agreement even though the accepting or
acquiescing party had knowledge of the nature of the performance and opportunity for objection. 
 (n)     
Compliance with Orders. Notwithstanding the security interest granted to the Trustee herein or any other terms set forth in this Agreement, in the event that a legal garnishment, attachment, levy restraining notice, court order or other
governmental order is served with respect to any of the Senior Secured Escrowed Property, or the delivery thereof shall be stayed or enjoined by an order of a court, the Escrow Agent is hereby expressly authorized, in its sole discretion (with
prompt notice to the Trustee and the Escrow Issuer to the extent permitted by applicable law; provided that the Escrow Agent shall endeavor to provide such notice prior to any such compliance), to obey and comply with all such

  
 -19- 

 
orders so entered or issued, and in the event that the Escrow Agent obeys or complies with any such order, levy restraining notice, legal garnishment, attachment or other governmental order, it
shall not be liable to any of the Parties hereto or to any other person by reason of such compliance notwithstanding such order, levy restraining notice, legal garnishment, attachment or other governmental order, be subsequently reversed, modified,
annulled, set aside or vacated. 
 (o)      Information. The Parties authorize the Escrow Agent to
disclose information with respect to this Agreement and the account(s) established hereunder, the Parties, or any transaction hereunder if such disclosure is: (i) necessary or desirable, in the Escrow Agent’s reasonable opinion, for the
purpose of allowing the Escrow Agent to perform its duties and to exercise its powers and rights hereunder or for operational or risk management purposes or compliance with legal, tax and regulatory requirements, including, without limitation,
FATCA; (ii) to a proposed assignee of the rights of the Escrow Agent; (iii) to a branch, affiliate, subsidiary, employee or agent of the Escrow Agent or to their auditors, regulators or legal advisers or to any competent court;
(iv) to the auditors of any of the Parties; or (v) permitted or required by applicable law, regardless of whether the disclosure is made in the country in which each Party resides, in which the Escrow Accounts are maintained, or in which
the transaction is conducted. The Parties agree that such disclosures by the Escrow Agent and its affiliates may be transmitted across national boundaries and through networks, including those owned by third parties. 

(p)      Miscellaneous. To the extent that in any jurisdiction either Party may now or hereafter be entitled
to claim for itself or its assets, immunity from suit, execution, attachment (before or after judgment) or other legal process, such Party shall not claim, and hereby irrevocably waives, such immunity. The Escrow Agent and the Parties further hereby
waive any right to a trial by jury with respect to any lawsuit or judicial proceeding arising or relating to this Agreement. No party to this Agreement is liable to any other party for losses due to, or if it is unable to perform its obligations
under the terms of this Agreement because of, acts of God, fire, war, terrorism, floods, strikes, electrical outages, equipment or transmission failure or other causes reasonably beyond its control. If any provision of this Agreement is determined
to be prohibited or unenforceable by reason of any applicable law of a jurisdiction, then such provision shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining
provisions thereof, and any such prohibition or unenforceability in such jurisdiction shall not invalidate or render unenforceable such provisions in any other jurisdiction. The Parties each represent, warrant and covenant that (i) each
document, notice, instruction or request provided by such Party to Escrow Agent shall comply with applicable laws and regulations, (ii) such Party has full power and authority to enter into, execute and deliver this Agreement and to perform all
of the duties and obligations to be performed by it hereunder and (iii) the person(s) executing this Agreement on such Party’s behalf and certifying Authorized Representatives in Schedule I-A
and Schedule I-B have been duly and properly authorized to do so, and each Authorized Representative of such Party has been duly and properly authorized to take the actions specified for such person in
Schedule I-A and Schedule I-B.

AMENDMENT NO. 2 TO STOCKHOLDER RIGHTS AGREEMENT

This Amendment No. 2 to Stockholder Rights Agreement (this “Amendment”) is made effective as of the 12th day of August, 2021. This Amendment is an amendment to the Stockholder Rights Agreement, dated as of September 22, 2020, and amended on March 12, 2021 (as amended, the “Rights Agreement”), between Stratus Properties Inc., a Delaware corporation (the “Company”), and Computershare Inc., a Delaware corporation, as rights agent (the “Rights Agent”). The Company and the Rights Agent are collectively referred to as the “Parties.” Capitalized terms used and not otherwise defined herein have the meanings ascribed to them in the Rights Agreement.

RECITALS

WHEREAS, the Parties entered into the Rights Agreement on September 22, 2020, as amended on March 12, 2021; 

WHEREAS, the Board of Directors has determined that it is in the best interests of the Company and its stockholders to amend the Rights Agreement as set forth in this Amendment;

WHEREAS, pursuant to Section 27 of the Rights Agreement, the Company may, and the Rights Agent shall, if directed by the Company, from time to time supplement or amend the Rights Agreement without the approval of any holders of Rights, in accordance with the terms of such Section 27; and

WHEREAS, the Company has delivered to the Rights Agent a certificate from an appropriate officer of the Company that states that this Amendment complies with the terms of the Rights Agreement and has directed the Rights Agent to amend the Rights Agreement as set forth herein. 

NOW THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the Parties hereby agree as follows:

Section 1. Amendment to Rights Agreement. 

(a)Section 7(a) of the Rights Agreement is hereby amended by deleting, in its entirety, clause (i) related to the definition of “Final Expiration Time” and replacing it with the following new clause (i): “(i) the Close of Business on August 12, 2021 (the “Final Expiration Time”),”.

(b)All references to the date of “September 22, 2023” in Exhibit B (Summary of Rights to Purchase Series D Participating Cumulative Preferred Stock) and Exhibit C (Form of Rights Certificate) to the Rights Agreement shall hereby be changed to “August 12, 2021”.

Section 2. Remaining Terms; Controlling Agreement. All other provisions of the Rights Agreement that are not expressly amended hereby shall continue in full force and effect. 

Notwithstanding the foregoing, the Rights Agent and the Company acknowledge and agree that upon the Expiration Time the Rights Agreement shall terminate and be of no further force and effect, except for the provisions which by their express terms shall survive such termination. From and after the execution and delivery of this Amendment, any references to the Rights Agreement in the Rights Agreement and other agreements or instruments shall be deemed to refer to the Rights Agreement as amended pursuant to this Amendment. In the event of any conflict between the terms of this Amendment and the Rights Agreement, this Amendment shall control.

Section 3. Severability. If any term, provision, covenant or restriction of this Amendment is held by a court of competent jurisdiction or other authority to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions of this Amendment shall remain in full force and effect and shall in no way be affected, impaired or invalidated; provided, however, that, notwithstanding anything in this Amendment to the contrary, if any such term, provision, covenant or restriction is held by such court or authority to be invalid, void or unenforceable and the Board determines in its good faith judgment that severing the invalid language from this Amendment would adversely affect the purpose or effect of this Amendment, the right of redemption set forth in Section 23 of the Rights Agreement shall be reinstated and shall not expire until the Close of Business on the tenth day following the date of such determination by the Board.

Section 4. Governing Law. This Amendment shall be deemed to be a contract made under the laws of the State of Delaware and for all purposes shall be governed by and construed in accordance with the laws of such state applicable to contracts to be made and performed entirely within such state, provided, however, that all provisions regarding the rights, duties, liabilities and obligations of the Rights Agent shall be governed by and construed in accordance with the laws of the State of New York applicable to contracts made and to be performed entirely within such State.

Section 5. Descriptive Headings. Descriptive headings of the sections of this Amendment are inserted for convenience only and shall not control or affect the meaning or construction of any of the provisions hereof.

Section 6. Counterparts. This Amendment may be executed in one or more counterpart, each of which shall be deemed to be an original, but all of which shall constitute one and the same agreement. Delivery of an executed signature page of this Amendment by facsimile or other customary means of electronic transmission (e.g., “pdf”) shall be as effective as delivery of a manually executed counterpart hereof.
