(a) The Bank may employ agents or attorneys-in-fact which are not affiliates of the Bank with the prior written consent of the Trust (which
consent shall not be unreasonably withheld), and shall not be liable for any loss or expense arising out of, or in connection with, the actions or omissions to act of such agents or attorneys-in-fact, provided that the Bank acts in good faith and

 (b) The Bank may, without the prior consent of
the Trust, enter into subcontracts, agreements and understandings with any Bank affiliate, whenever and on such terms and conditions as it deems necessary or appropriate to perform its services hereunder. No such subcontract, agreement or
understanding shall discharge Bank from its obligations hereunder. 
 7.2 The Bank shall be entitled to conclusively rely upon any written
or oral instruction actually received by the Bank and reasonably believed by the Bank to be duly authorized and delivered. The Trust agrees to forward to the Bank written instructions confirming oral instructions by the close of business of the same
day that such oral instructions are given to the Bank. The Trust agrees that the fact that such confirming written instructions are not received or that contrary written instructions are received by the Bank shall in no way affect the validity or
enforceability of transactions authorized by such oral instructions and effected by the Bank. If the Trust elects to transmit written instructions through an on-line communication system offered by the Bank, Trust’s use thereof shall be subject
to the terms and conditions attached hereto as Exhibit B. 
 7.3 The Bank shall establish and maintain a disaster recovery plan and back-up
system at all times satisfying the requirements of its regulators (the “Disaster Recovery Plan and Back-Up System”). The Bank shall not be responsible or liable for any failure or delay in the performance of its obligations under this

disturbances; sabotage; epidemics; riots; interruption, loss or malfunctions of transportation, computer (hardware or software) or communication services; labor disputes; acts of civil or military authority; governmental actions; or inability to

and was maintaining the Disaster Recovery Plan and Back-Up System. Upon the occurrence of any such delay or failure the Bank shall use commercially reasonable best efforts to resume performance as soon as practicable under the circumstances. 

7.4 The Bank shall have no duties or responsibilities whatsoever except such duties and responsibilities as are specifically set forth in this
Agreement and the Participation Agreement, and no covenant or obligation shall be implied against the Bank in connection with this Agreement, except as set forth in this Agreement and the Participation Agreement.

matter arising in connection with the Bank’s duties and 

  
 6 

 
obligations under this Agreement, and the Bank, its agents, and subcontractors shall not be liable for any action taken or omitted to be taken in good faith in accordance with such instructions.
Such application by the Bank for instructions from an officer of the Trust may, at the option of the Bank, set forth in writing any action proposed to be taken or omitted to be taken by the Bank with respect to its duties or obligations under this
Agreement and the date on and/or after which such action shall be taken, and the Bank shall not be liable for any action taken or omitted to be taken in good faith in accordance with a proposal included in any such application on or after the date
specified therein unless, prior to taking or omitting to take any such action, the Bank has received written or oral instructions in response to such application specifying the action to be taken or omitted. In connection with the foregoing, the
Bank may consult with legal counsel of its own choosing, but is not obligated to do so, and advise the Trust if any instructions provided by the Trust at the request of the Bank pursuant to this Article or otherwise would, to the Bank’s
knowledge, cause the Bank to take any action or omit to take any action contrary to any law, rule, regulation or commercially reasonable practice for similarly situated service providers. In the event a situation or circumstance arises whereby the
Bank adopts a course of conduct in reliance upon written legal advice it has received (which need not be a formal opinion of counsel) and the course of conduct is not identical to the course of conduct contained in the instructions received from the
Trust, the Bank may reply upon and follow the written legal advice without liability hereunder provided it otherwise acts in compliance with this Agreement and notifies the Trust of its determination. 

7.6 The Bank, its agents and subcontractors may act upon any paper or document, reasonably believed to be genuine and to have been signed by
the proper person or persons, or upon any instruction, information, data, records or documents provided to the Bank or its agents or subcontractors by or on behalf of the Trust by machine readable input, telex, CRT data entry or other similar means
authorized by the Trust, and shall not be held to have notice of any change of authority of any person, until receipt of written notice thereof from the Trust.

by the Bank hereunder. Notwithstanding the foregoing, the parties hereto acknowledge that the Trust shall retain all ownership rights in Trust data residing on the Bank’s electronic system. 

7.8 Notwithstanding any provisions of this Agreement to the contrary, the Bank shall be under no duty or obligation to inquire into, and shall
not be liable for: 
 (a) The legality of the issue, sale or transfer of any Shares, the sufficiency of the amount to be received in
connection therewith, or the authority of the Trust to request such issuance, sale or transfer; 
 (b) The legality of the purchase of any
Shares, the sufficiency of the amount to be paid in connection therewith, or the authority of the Trust to request such purchase;

Access by You is contingent upon and is in consideration for Your compliance with the terms and conditions set forth below. Electronic Access includes access to BNY Mellon web sites accessible via BNY Mellon Connect and/or other BNY
Mellon-designated access portals (“Sites”), pursuant to which You are able to access products and services provided by BNY Mellon as well as data regarding Your accounts. You may amend Schedule A by delivering a revised
version to BNY Mellon. 
 Any particular product or service accessed by You through Electronic Access may be subject to a separate written agreement between
You and BNY Mellon with respect to such products and services (each a “Services Agreement”). In addition, terms and conditions and restrictions with respect to any particular product or service accessed through Electronic
Access (such as privacy and internet security matters), together with any disclaimers related to the specific products or services, may be set forth on the Sites (hereinafter referred to as “Terms of Use”) and are applicable to such
products and services. You agree to the Terms and Conditions. By any of Your Users accessing the Sites, and the products and services available through Electronic Access, You agree to any Terms of Use and acknowledge and accept any disclaimers and
disclosures included on the Sites and the restrictions concerning the use of proprietary data provided by Information Providers (as defined below) that are posted on the Data Terms Web Site (as defined below). For the avoidance of doubt, the
execution of these Terms and Conditions will not alter or amend or otherwise affect any Services Agreement whether such Services Agreement is executed prior to or after the execution of these Terms and Conditions. 

 

	1.	Access Administration: 

  

	 	a.	To facilitate access to Electronic Access, You will furnish BNY Mellon with a written list of the names, and the extent of authority or level of access, of persons You are authorizing to access the Sites, products and
services and to use the Electronic Access (“Authorized Users”) on a read-only basis. In addition, You may also designate Authorized Users who will have authority to enter transactions and provide instructions to BNY Mellon
that cause a change in or have an impact on assets held by BNY Mellon for Your accounts (“Authorized Transactional Users”). Where appropriate, Authorized Users and Authorized Transactional Users are collectively referred to
herein as “Users.” If You wish to allow any third party (such as an investment manager, consultant or third party service provider) or any employee of a third party to have access to Your account information through
Electronic Access and be included as a “User” under these Terms and Conditions, You may designate a third party or employee of a third party as an Authorized User or Authorized Transactional User under these Terms and Conditions and any
such third party or employee of a third party so designated by You (and, if a third party is so designated, any employee of such third party designated by such third party) will be included within the definition of Authorized User, Authorized
Transactional User, and User as appropriate. 

  

	 	b.	 Upon BNY Mellon’s approval of Users (which approval will not be unreasonably withheld), BNY Mellon will send
You a user-id, temporary password and, where applicable, a security identification device for each User. You will be responsible for providing to Users the user-ids, temporary passwords and, where applicable, secure identification devices. You will
ensure that any User receiving a secure identification device returns such device immediately following the termination of the User’s authorization to access the products and services for which the secure identification device was provided to
such User. You are solely responsible for Users’ access to Electronic Access, and You and Users are solely responsible for the confidentiality of the user-ids and passwords and secure identification devices that are provided to them and will
remain responsible for each secure identification device until it is returned to BNY Mellon. You, 

  
 16 

	 	
on behalf of You and Your affiliates, acknowledge and agree that, BNY Mellon will have no duty or obligation to verify or confirm the actual identity of the person who accessed Electronic Access
using a validly issued user-id and password (and, where applicable, security identification device) or that the person who accessed Electronic Access using such validly issued user-id and password (and, where applicable, security identification
device) is, in fact, a User (whether an Authorized User or an Authorized Transactional User). 

  

	 	c.	You shall not, and shall not permit any User or third party to, breach or attempt to breach any security measures used in connection with Electronic Access or Proprietary Software. Any attempt to circumvent or penetrate
any application, network or other security measures used by BNY Mellon or its suppliers in connection with Electronic Access is strictly prohibited. 

  

	 	d.	You are also solely responsible for ensuring that all Users comply with these Terms and Conditions and any Terms of Use included on the Sites, the Service Agreement for each product or services accessed through the
Sites and their associated services and all applicable terms and conditions, restrictions on the use of such products and services and data obtained through the use of Electronic Access. BNY Mellon reserves the right to prohibit access or revoke the
access of any User to Electronic Access whom BNY Mellon determines has violated or breached these terms and conditions or any Terms of Use on a Site accessed by the User, including the Data Terms Web Site (as defined below), or whose conduct BNY
Mellon reasonably determines may constitute a criminal offense, violate any applicable local, state, national, or international law or constitute a security risk for BNY Mellon, a BNY Mellon’s third party supplier (“BNY Mellon’s
Supplier”), BNY Mellon’s clients or any Users of Electronic Access. BNY Mellon may also terminate access to all Users following termination of all Services Agreements between You and BNY Mellon. 

 

	2.	Proprietary Software: Depending upon the products and services You elect to access through Electronic Access, You may be provided software owned by BNY Mellon or licensed to BNY Mellon by a BNY
Mellon Supplier (“Proprietary Software”). You are granted a limited, non-exclusive, non-transferable license to install the Proprietary Software on Your authorized computer system (including mobile devices registered with BNY
Mellon) and to use the Proprietary Software solely for Your own internal purposes in connection with Electronic Access and solely for the purposes for which it is provided to You. You and Your Users may make copies of the Proprietary Software for
backup purposes only, provided all copyright and other proprietary information included in the original copy of the Proprietary Software are reproduced in or on such backup copies. You shall not reverse engineer, disassemble, decompile or attempt to
determine the source code for, any Proprietary Software. Any attempt to circumvent or penetrate security of Electronic Access is strictly prohibited. 

  

	3.	Use of Data:  

  

	 	a.	Electronic Access may include information and data that is proprietary to the providers of such information or data (“Information Providers”) or may be used to access Sites that include such
information or data from Information Providers. This information and data may be subject to restrictions and requirements which are imposed on BNY Mellon by the Information Providers and which are posted on
http://www.bnymellon.com/products/assetservicing/vendoragreement.pdf or any successor web site of which You are provided notice from time to time (the “Data Terms Web Site”). You will be solely responsible for ensuring that
Users comply with the restrictions and requirements concerning the use of proprietary data that are posted on the Data Terms Web Site. 

  

	 	b.	You consent to BNY Mellon, its affiliates and BNY Mellon’s Suppliers disclosing to each other and using data received from You and Users and, where applicable, Your third parties in connection with these Terms and
Conditions (including, without limitation, client data and personal data of Users) (1) to the extent necessary for the provision of Electronic Access; (2) in order for BNY Mellon and its affiliates to meet any of their obligations under
these Terms and Conditions to provide Electronic Access; or (3) to the extent necessary for Users to access Electronic Access. 

  
 17 

	 	c.	In addition, You permit BNY Mellon to aggregate data concerning Your accounts with other data collected and/or calculated by BNY Mellon. BNY Mellon will own such aggregated data, but will not distribute the aggregated
data in a format that identifies You or Your data. 

  

	4.	Ownership and Rights: 

  

	 	a.	Electronic Access, including any database, any software (including for the avoidance of doubt, Proprietary Software) and any proprietary data, processes, scripts, information, training materials, manuals or
documentation made available as part of the Electronic Access (collectively, the “Information”), are the exclusive and confidential property of BNY Mellon and/or BNY Mellon’s suppliers. You may not use or disclose the
Information except as expressly authorized by these Terms and Conditions. You will, and will cause Users and Your third parties and their users, to keep the Information confidential by using the same care and discretion that You use with respect to
Your own confidential information, but in no event less than reasonable care. 

  

	 	b.	The provisions of this paragraph will not affect the copyright status of any of the Information which may be copyrighted and will apply to all Information whether or not copyrighted. 

 

	 	c.	Nothing in these Terms and Conditions will be construed as giving You or Users any license or right to use the trade marks, logos and/or service marks of BNY Mellon, its affiliates, its Information Providers or BNY
Mellon’s Suppliers. 

  

	 	d.	Any Intellectual Property Rights and any other rights or title not expressly granted to You or Users under these Terms and Conditions are reserved to BNY Mellon, its Information Providers and BNY Mellon’s
Suppliers. “Intellectual Property Rights” includes all copyright, patents, trademarks and service marks, rights in designs, moral rights, rights in computer software, rights in databases and other protectable lists of information, rights
in confidential information, trade secrets, inventions and know-how, trade and business names, domain names (including all extensions, revivals and renewals, where relevant) in each case whether registered or unregistered and applications for any of
them and the goodwill attaching to any of them and any rights or forms of protection of a similar nature and having equivalent or similar effect to any of them which may subsist anywhere in the world. 

 

	5.	Reliance:  

  

	 	a.	BNY Mellon will be entitled to rely on, and will be fully protected in acting upon, any actions or instructions associated with a user-id or a secure identification device issued to a User until such time BNY Mellon
receives actual notice in writing from You of the change in status of the User and receipt of the secure identification device issued to such User. You acknowledge that all commands, directions and instructions, including commands, directions and
instructions for transactions issued by a User are issued at Your sole risk. You agree to accept full and sole responsibility for all such commands, directions and instructions and that BNY Mellon, will have no liability for, and you hereby release
BNY Mellon from, any losses, liabilities, damages, costs, expenses, claims, causes of action or judgments (including attorneys fees and expenses) (collectively “Losses”) incurred or sustained by you or any other party in
connection with or as a result of BNY Mellon’s reliance upon or compliance with such commands, directions and instructions. 

  

	 	b.	All commands, directions and instructions involving a transaction entered by Authorized Transactional User will be treated as an authorized instruction under the applicable Services Agreement(s) between You and BNY
Mellon covering accounts, products and services and products provided by BNY Mellon with respect to which Electronic Access is being used whether such Services Agreement is executed prior to or after the execution of these Terms and Conditions.

  

	6.	Disclaimers: 

  

	 	a.	 Although BNY Mellon uses reasonable efforts to provide accurate and up-to-date information through Electronic
Access, BNY Mellon, its Content Providers and Information Providers make no warranties or 

  
 18 

	 	
representations under these Terms and Conditions as to accuracy, reliability or comprehensiveness of the content, information or data accessed through Electronic Access. Without limiting the
foregoing, some of the content on Electronic Access may be provided by sources unaffiliated with BNY Mellon (“Content Providers”) and by Information Providers. For that content BNY Mellon is a distributor and not a publisher
of such content and has no control over it. Information provided by Information Providers has not been independently verified by BNY Mellon and BNY Mellon makes no representation as to the accuracy or completeness of the content or information
provided. Any opinions, advice, statements, services, offers or other information given or provided by Content Providers and Information Providers (including merchants and licensors) are those of the respective authors of such content and not
that of BNY Mellon. BNY Mellon will not be liable to You or Users for such content or information in any way nor for any action taken in reliance on such information nor for direct or indirect damages resulting from the use of such information.
For purposes of these Terms and Conditions, all information and data, including all proprietary information and materials and all client data, provided to You through Electronic Access are provided on an “AS-IS”, “AS AVAILABLE”
basis. 

  

	 	b.	BNY Mellon makes no guarantee and does not warrant that Electronic Access or the information and data provided through the Electronic Access are or will be virus-free or will be free of viruses, worms, Trojan horses or
other code with contaminating or destructive properties. BNY Mellon will employ commercially reasonable anti-virus software to its systems to protect its systems against viruses. 

 

	 	c.	Some Sites accessed through the use of Electronic Access may include links to websites provided by parties that are not affiliated with BNY Mellon (“Third Party Websites”). BNY Mellon will not be
liable to any person for the content found on such Third Party Websites. BNY Mellon will not be responsible for Third Party Websites that collect information from parties who visit their web sites through links on the Sites. BNY Mellon will not be
liable or responsible for any loss suffered by any person as a result of their use of any Third Party Websites that are linked to the BNY Mellon Sites. 

  

	 	d.	BNY Mellon retains complete discretion and authority to add, delete or revise in whole or in part Electronic Access, including its Sites, and to modify from time to time any Proprietary Software provided in conjunction
with the use of Electronic Access and/or any of the Sites. To the extent reasonably possible, BNY Mellon will provide notice of such modifications. BNY Mellon may terminate, immediately and without advance notice, and without right of cure, any
portion or component of Electronic Access or the Sites. 

  

	 	e.	TO THE FULLEST EXTENT PERMITTED BY LAW, THERE IS NO WARRANTY OF MERCHANTABILITY, NO WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE, NO WARRANTY OF QUALITY AND NO WARRANTY OF TITLE OR NONINFRINGEMENT. THERE IS NO OTHER
WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, REGARDING ELECTRONIC ACCESS, THE SITES, ANY PROPRIETARY SOFTWARE, INFORMATION, MATERIALS OR CLIENT DATA. 

  

	 	f.	Notwithstanding the prior paragraph, The Bank of New York Mellon or an Affiliate designated by it will defend You and pay any amounts agreed to by BNY Mellon in a settlement and damages finally awarded by a court of
competent jurisdiction, in an action or proceeding commenced against You based on a claim that Electronic Access or the Proprietary Software infringe plaintiff(s)’s patent, copyright, or trade secret, provided that You (i) notify BNY
Mellon promptly of any such action or claim (except that the failure to so notify BNY Mellon will not limit BNY Mellon’s obligations hereunder except to the extent that such failure prejudices BNY Mellon); (ii) grant BNY Mellon or its
designated Affiliate full and exclusive authority to defend, compromise or settle such claim or action; and (iii) provide BNY Mellon or its designated Affiliate all assistance reasonably necessary to so defend, compromise or settle. The
foregoing obligations will not apply, however, to any claim or action arising from (i) use of the Proprietary Software Information or Electronic Access in a manner not authorized under these Terms and Conditions, the Terms of Use, or the Data
Terms Web Site; or (ii) use of the Proprietary Software or Electronic Access in combination with other software or services not supplied by BNY Mellon.

	7.	Limitation of Liability: 

  

	 	a.	IN NO EVENT WILL BNY MELLON, BNY MELLON’S SUPPLIERS OR ITS CONTENT PROVIDERS OR INFORMATION PROVIDERS BE LIABLE TO YOU OR ANYONE ELSE UNDER THESE TERMS AND CONDITIONS FOR ANY LOSSES, LIABILITIES, DAMAGES, COSTS OR
EXPENSES INCLUDING BUT NOT LIMITED TO, ANY DIRECT DAMAGES, CONSEQUENTIAL DAMAGES, RELIANCE DAMAGES, EXEMPLARY DAMAGES, INCIDENTAL DAMAGES, SPECIAL DAMAGES, PUNITIVE DAMAGES, INDIRECT DAMAGES OR DAMAGES FOR LOSS OF PROFITS, GOOD WILL, BUSINESS
INTERRUPTION, USE, DATA, EQUIPMENT OR OTHER INTANGIBLE LOSSES (EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES) THAT RESULT FROM (1) THE USE OF OR INABILITY TO USE ELECTRONIC ACCESS (2) THE CONSEQUENCES OF ANY DECISION MADE
OR ACTION OR NON-ACTION TAKEN BY YOU OR ANY OTHER PERSON, OR FOR ANY ERRORS BY YOU IN COMMUNICATING SUCH INFORMATION; (3) THE COST OF SUBSTITUTE ACCESS SERVICES; OR (4) ANY OTHER MATTER RELATING TO THE CONTENT OR ACCESS THROUGH ELECTRONIC
ACCESS. BNY MELLON WILL NOT BE LIABLE FOR LOSS, DAMAGE OR INJURY TO PERSONS OR PROPERTY ARISING FROM ANY USE OF ANY PRODUCT, INFORMATION, PROCEDURE, OR SERVICE OBTAINED THROUGH ELECTRONIC ACCESS. BNY MELLON WILL NOT BE LIABLE FOR ANY LOSS, DAMAGE OR
INJURY RESULTING FROM VOLUNTARY SHUTDOWN OF THE SERVER, ELECTRONIC ACCESS OR ANY OF THE SITES TO ADDRESS TECHNICAL PROBLEMS, COMPUTER VIRUSES, DENIAL-OF-SERVICE MESSAGES OR OTHER SIMILAR PROBLEMS. 

 

	 	b.	BNY MELLON’S ENTIRE LIABILITY AND YOUR EXCLUSIVE REMEDY UNDER THESE TERMS AND CONDITIONS FOR ANY DISPUTE OR CLAIM RELATED TO THESE TERMS OF USE, ELECTRONIC ACCESS OR SITES, IS AS FOLLOWS: IF YOU REPORT A MATERIAL
MALFUNCTION IN ELECTRONIC ACCESS THAT BNY MELLON IS ABLE TO REPRODUCE, BNY MELLON WILL USE REASONABLE EFFORTS TO CORRECT THE MALFUNCTION. IF BNY MELLON IS UNABLE TO CORRECT THE MALFUNCTION, YOU MAY CEASE ALL USE OF ELECTRONIC ACCESS AND RECEIVE A
REFUND OF ANY FEES PAID IN ADVANCE, SPECIFICALLY FOR ELECTRONIC ACCESS, APPLICABLE TO PERIODS AFTER CESSATION OF SUCH USE. BECAUSE SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OR LIMITATION OF LIABILITY FOR DAMAGES, IN SUCH JURISDICTIONS LIABILITY
IS LIMITED TO THE FULLEST EXTENT PERMITTED BY LAW. 

  

	 	c.	The limitation of liability set forth in this Limitation of Liability section and in other provisions in these Terms and Conditions is in addition to any limitation of liability provisions contained in any Services
Agreements and will not supersede or be superseded by limitation of liability provisions contained in such Services Agreements, whether executed prior to or after the execution of these Terms and Conditions, except to the extent specifically set
forth in such other Services Agreements containing a reference to these Terms and Conditions. 

  

	8.	Indemnification: 

  

	 	a.	You agree to indemnify, protect and hold BNY Mellon, BNY Mellon’s Suppliers, Content Providers and Information Providers harmless from and against all liability, claims damages, costs and expenses, including
reasonable attorneys’ fees and expenses, resulting from a claim that arises out of (i) any breach by You or Users of these Terms and Conditions, the Terms of Use or the Data Terms Web Site and (ii) any person obtaining access to
Electronic Access through You or Users or through use of any password, user-id or secure identification device issued to a User, whether or not You or a User authorized such access. For the avoidance of doubt, and by way of illustration and not by
way of limitation, the forgoing indemnity is applicable to disputes between the parties, including the enforcement of these Terms and Conditions. The rights and remedies conferred hereunder will be cumulative and the exercise or waiver of any such
right or remedy will not preclude or inhibit the exercise of additional rights or remedies or the subsequent exercise of such right or remedy. 

  

	 	b.	 The indemnity provided in herein is in addition to any indemnity and other remedies contained in any Services
Agreements and will not supersede or be superseded by such Services Agreements, whether 

  
 20 

 
executed prior to or after the execution of these Terms and Conditions, except to the extent specifically set forth in such other Services Agreements and expressly stating an intent to modify
this Terms and Conditions. Nothing contained herein will, or be deemed to, alter or modify the rights and remedies of BNY Mellon as set forth in the Services Agreements. 
  

	9.	Choice of Law and Forum: Unless otherwise agreed and specified herein, these Terms and Conditions are governed by and construed in accordance with the laws of the State of New York, without giving
effect to any principles of conflicts of law; You expressly and irrevocably agree that exclusive jurisdiction and venue for any claim or dispute with BNY Mellon, its employees, contractors, officers or directors or relating in any way to Your use of
Electronic Access resides in the state or federal courts in New York City, New York; and You further irrevocably agree and expressly and irrevocably consent to the exercise of personal jurisdiction in those courts over any action brought with
respect to these Terms and Conditions. BNY Mellon and You hereby waive the right of trial by jury in any action arising out of or related to the BNY Mellon or these Terms and Conditions.

	 	a.	Either BNY Mellon or You may terminate these Terms and Conditions and the Electronic Access upon thirty (30) days’ written notice to the other party. 

 

	 	b.	In the event of any breach of the provisions of these Terms and Conditions or a breach by any Authorized User of the Terms of Use or the restrictions and requirements concerning the use of Information Providers’
proprietary data that are posted on the Data Terms Web Site, the non-breaching party may terminate these Terms and Conditions and the Electronic Access immediately upon written notice to the breaching party if any breach remains uncured after ten
(10) days’ written notice of the breach is sent to the breaching party. 

  

	 	c.	BNY Mellon may immediately terminate access through an Authorized User’s user-id and password and may, at its discretion, also terminate access by an Authorized User, without right of cure, in the event of an
unauthorized use of an Authorized User’s user-id or password, or where BNY Mellon believes there is a security risk created by such access. 

  

	 	d.	BNY Mellon may terminate, without advance notice, Your access or the access of Users to any portion or component of Electronic Access or the Sites in the event a BNY Mellon Supplier, Content Provider or Information
Provider prohibits BNY Mellon from permitting You or Users to have access to their information or services. 

  

	 	e.	Promptly upon receiving or giving notice of termination, You will notify all Users of the effective date of the termination. 

  

	 	f.	Upon termination of Your access to Electronic Access, You shall return of manuals, documentation, workflow descriptions and the like that are in Your possession or under Your control and all security identification
devices. 

  

	 	g.	The Reliance, Disclaimers, Limitation of Liability Indemnification and confidentiality provisions of the Terms and Conditions (and other provision of these Terms and Conditions containing disclaimers, limitation of
liability and indemnification) shall survive the termination of these Terms and Conditions. 

 You represent and warrant to BNY Mellon that
these Terms and Conditions and the indemnity contained herein have been duly authorized and accepted, that You have full authority to enter into these Terms and Conditions, both for the entities at Schedule A and for any affiliate with Electronic

of the persons providing such instructions. 
 15. Severability. In the event any provision of this Agreement is adjudicated
to be void, illegal, invalid or unenforceable, the remaining terms and provisions of this Agreement shall not be affected thereby, and each of such remaining terms and provisions shall be valid and enforceable to the fullest extent permitted by law,
unless a party demonstrates by a preponderance of the evidence that the invalidated provision was an essential economic term of this Agreement.

concurrently with this Agreement contain the entire agreement between the parties with respect to the transactions contemplated hereby and supersede all previous oral or written negotiations, commitments and understandings related thereto. This
Agreement may not be amended or modified in any respect, nor may any provision be waived, without the written agreement of both parties. No waiver by one party of any obligation of the other hereunder shall be considered a waiver of any other
