Upon termination of this Agreement pursuant to this paragraph with respect to the Fund or any Portfolio, the Fund or applicable Portfolio shall pay Transfer Agent its compensation due and shall reimburse Transfer Agent for its costs, expenses and disbursements. Termination of this Agreement with respect to any one particular Portfolio shall in no way affect the rights and duties under this Agreement with respect to the Fund or any other Portfolio.

In addition, the Fund may terminate this Agreement during the Initial Term and thereafter with respect to a Portfolio if, in the Fund’s reasonable opinion, the Transfer Agent has persistently not achieved the performance measures set forth in any service level document (a “Service Level Document”) that may be established in good faith by the parties as key identified performance measures, and a plan or revised plan has not been put into place in accordance with the following procedures: In the event that the Transfer Agent has persistently not met the key identified performance measures set forth in the Service Level Document during any two (2) months of any calendar quarter (as such failure is set forth in the Service Level Document), the Fund may, in its discretion, submit a written deficiency notice to the Transfer Agent outlining the performance deficiencies (“Deficiency Notice”). Such Deficiency Notice shall be provided to the Transfer Agent within twenty (20) days of the end of such calendar quarter. After receipt of such notice, the Transfer Agent shall present the Fund with a written plan (the “Plan”) to address the deficiencies set forth in the Deficiency Notice. Such Plan must be provided to the Fund within thirty (30) days after receipt of the Deficiency Notice. If the Transfer Agent fails to submit a Plan within such 30-day period, the Fund may terminate this Agreement upon sixty (60) days’ written notice to the Transfer Agent. The Fund, in its discretion, may accept or reject the Plan by notifying the Transfer Agent in writing (“Plan Notice”) within fifteen (15) days after receipt of the Plan. If the Fund fails to provide a Plan Notice within such 15-day period, it shall be presumed that the Fund accepted the Plan. In the event the Fund submits a Plan Notice rejecting the Plan, the Transfer Agent shall submit a revised plan (“Revised Plan”) within thirty (30) days after provision of such Plan Notice. If the Transfer Agent fails to submit a Revised Plan within such 30-day period, the Fund may terminate the Agreement upon sixty (60) days’ written notice to the Transfer Agent. The Fund, in its discretion, may accept or reject the Revised Plan by notifying the Transfer Agent in writing (“Revised Plan Notice”) within fifteen (15) days after receipt of the Revised Plan. If the Fund fails to provide a Revised Plan Notice within such 15-day period, it shall be presumed that the Fund accepted the Revised Plan. If the Fund provides a Revised Plan Notice to the Transfer Agent that rejects the Revised Plan, the Fund may, in its discretion, terminate this Agreement upon sixty (60) days’ written notice to the Transfer Agent. Such termination notice must be submitted to the Transfer Agent within sixty (60) days after provision of the Revised Plan Notice.

10.2 Continuation for Wind Down Period. In the event of a termination of this Agreement as of the scheduled expiration of the Initial Term or thereafter, the Fund shall have the option upon forty-five (45) days prior written notice to the Transfer Agent, to extend the term of this Agreement by up to twelve (12) months (the “Wind-Down Period”) in order to facilitate the movement of the Fund’s data and records to a new service provider. The Transfer Agent shall be compensated by the Fund during such Wind-Down Period in accordance with the terms of this Agreement for the term for which it is being extended.

10.3 Deconversion. In the event that this Agreement is terminated or not renewed for any reason by the Fund, the Transfer Agent and the Fund shall mutually agree to the manner and method in which deconversion services are to be provided to the Fund, and the compensation to be provided by the Fund for such deconversion services.

10.4 Loss of Transfer Agent Registration; Change of Control. In addition to any right to terminate set forth in this Agreement, the Fund shall have the right to terminate this Agreement by delivery of written notice to the Transfer Agent, such termination to take effect not sooner than six (6) months after the date of such delivery, if the Transfer Agent (a) ceases to be registered as a transfer agent under the 1934 Act and has failed to initiate appropriate action to reinstate such

registration or has publicly expressed its intention to cease its transfer agency business or (b) experiences any transfer of ownership of a controlling interest by or to any person other than an entity which was an affiliate of the Transfer Agent immediately before any such transfer.

11. ADDITIONAL ETF CLASSES

In the event that the Fund establishes one or more classes of exchange-traded shares in addition to the ETF Classes listed on the attached Schedule A, with respect to which the Fund desires to have the Transfer Agent render services as transfer agent under the terms hereof, it shall so notify the Transfer Agent in writing, and if the Transfer Agent agrees in writing to provide such services, such classes of exchange-traded shares shall become an ETF Class hereunder.

12.	ASSIGNMENT

12.1

Except as provided in Section 13 below, neither this Agreement nor any rights or obligations hereunder may be delegated or assigned by either party without the prior written consent of the other party, which shall not be unreasonably withheld.

The Transfer Agent shall be responsible for the services delivered by, and the acts and omissions of, any such Delegate as if the Transfer Agent had provided such services and committed such acts and omissions itself. The Transfer Agent shall be responsible for the compensation of its Delegates. Where required, such Delegate shall be a duly registered transfer agent pursuant to Section 17A(c)(2) of the 1934 Act.

13.2

The Transfer Agent will provide the Fund with information regarding its global operating model for the delivery of the services on a quarterly or other periodic basis, which information shall include the identities of Delegates affiliated with the Transfer Agent that perform or may perform parts of the services, and the locations from which such Delegates perform services, as well as such other information about its Delegates as the Fund may reasonably request from time to time. Nothing in this Section 13 shall limit or restrict the Transfer Agent’s right to use affiliates or third parties to perform or discharge, or assist it in the performance or discharge, of any obligations or duties under this Agreement other than the provision of the services.
