4.    AST’s Reliance.

a.    AST may act and rely on, and shall incur no liability and shall be fully indemnified by each Fund (severally and not jointly) from any liability whatsoever in acting in accordance with, written or oral instructions received from any person it believes in good faith to be an officer, authorized agent or employee of the Fund, unless prior thereto (i) the Fund shall have advised AST in writing that it is entitled to act and rely only on written instructions of designated officers of the Fund; (ii) it furnishes AST with an appropriate incumbency certificate for such officers and their signatures; and (iii) the Fund thereafter keeps such designation current with an annual (or more frequent, if required) re-filing. AST may also act and rely on advice, opinions or instructions received from the Funds’ legal counsel. AST may, in any event, act and rely on advice received from its legal counsel at its own expense, provided that AST acts reasonably pursuant to such advice.

b.    AST may act and rely on, and shall incur no liability and shall be fully indemnified by each Fund (severally and not jointly) from any liability whatsoever in acting in accordance with: (i) any writing or other instruction believed by it in good faith to have been furnished by or on behalf of the Fund or a holder of one or more its Shares (a “Shareholder”), including, but not limited to, any certificate, instrument, opinion, notice, letter, stock power, affidavit or other document or security; (ii) on any statement of fact contained in any such writing or instruction which AST in good faith does not believe to be inaccurate; (iii) on the apparent authority of any person to act on behalf of the Fund or a Shareholder as having actual authority to the extent of such apparent authority; (iv) on the authenticity and genuineness of any signature (manual or facsimile) appearing on any writing, including, but not limited to, any certificate, instrument, opinion, notice, letter, stock power, affidavit or other document or security; and (v) on the conformity to original of any copy. AST shall further be entitled to rely on any information, records and documents provided to AST by a former transfer agent or former registrar on behalf of the Fund.

5.    Compensation. AST shall be entitled to reasonable compensation for all services rendered and shall be reimbursed for all expenses incurred, including without limitation legal costs and costs of responding to subpoenas related to the a Fund’s records (regardless of whether AST is still an Agent for the Fund) in connection with its acting as Agent, as set forth in the attached Fee Schedule dated November 6, 2015. In the event that the scope of services to be provided by AST is increased substantially, the parties shall negotiate in good faith to determine reasonable compensation for

3

such additional services. In the event that a Fund, without terminating this Agreement in its entirety, retains a third-party to provide services already provided hereunder, the Fund shall pay to AST a reasonable fee to compensate AST for costs associated with interfacing with such third-party as mutually agreed upon by the Fund and AST. On termination of its services as Agent for any Fund, AST shall be entitled to reasonable additional compensation from such Fund for the service of preparing records for delivery to the successor agent or to the Fund, and for forwarding and maintaining records with respect to certificates received after such termination.

6.    Performance of Services. In the event that a Fund commits any breach of its material obligations to AST, including non-payment of any amount owing to AST, and such breach remains uncured for more than forty-five (45) days, AST shall have the right to terminate or suspend its services to such Fund upon notice to such Fund. During such time as AST may suspend its services to a Fund, AST shall have no obligation to act as transfer agent and/or registrar on behalf of such Fund and AST shall have no duties to act in such capacity. Such suspension shall not affect AST’s rights under this Agreement. In the event that AST commits any breach of its material obligations to a Fund and such breach remains uncured for more than forty-five (45) days, the Funds shall have the right to terminate this Agreement upon notice to AST. On termination of the appointment of AST for any reason, AST will perform its services in assisting with the transfer of records in a diligent and professional manner.

7.    Maintenance of Deposit Account. All funds received by AST for distribution on behalf of a Fund will, if so requested, be deposited by AST in a segregated bank account. Each Fund, which will, upon request, be given a copy of the bank’s statements for such account, shall have the responsibility to reconcile such account. Each Fund shall also have the responsibility to discharge all escheat obligations relating to such funds. If so requested by AST, each Fund shall, at its expense, furnish AST with a written opinion of its legal counsel regarding such obligations.

8.    Lost Certificates. AST shall be authorized to issue replacement certificates for stock certificates claimed by a Shareholder to have been lost, stolen or mutilated upon receipt of an affidavit of the Shareholder to such effect and receipt of payment from the Shareholder of a premium for an indemnity bond purchased through AST or, at the option of the Shareholder, any surety company reasonably acceptable to AST.

9.    Overissue. If AST receives a stock certificate not reflected in its records, AST will research records, if any, delivered to it upon its appointment as transfer agent from a prior transfer agent (or from a Fund). If such records do not exist or if such certificate cannot be reconciled with such records, then AST will notify the applicable Fund. If neither such Fund nor AST is able to reconcile such certificate with any records (so that the transfer of such certificate on the records maintained by AST would create an overissue), such Fund shall within sixty (60) days either: (i) increase the number of its issued Shares, or (ii) acquire and cancel a sufficient number of issued Shares, to correct the overissue.

10.    Confidentiality. AST acknowledges that it will acquire information and data from each Fund, and such information and data are confidential and proprietary information of the Funds (collectively, “Confidential Information”). Confidential Information may include, but shall not be limited to, information related to clients, business plans, shareholders, business processes, and other related

4

data, all in any form whether electronic or otherwise, that AST acquires in connection with this Agreement. Confidential Information will not include, however, any information that (i) was in the possession of AST at the commencement of the services contemplated under this Agreement, (ii) became part of the public domain through no fault of AST or (iii) became rightfully known to AST or its affiliates through a third party with no obligation of confidentiality to any Fund, or (iv) is independently developed by AST. AST agrees not to disclose the Confidential Information to others (except as required by law or permitted by AST’s privacy policy then in effect) or use it in any way, commercially or otherwise, except in performing services hereunder, and shall not allow any unauthorized person access to the Confidential Information. AST further agrees to exercise at least the same degree of care as it uses with regard to its own confidential information, but in no event less than reasonable degree of care, in protecting the Confidential Information.

11.    Limitations on AST’s Responsibilities. AST shall not be responsible for the validity of the issuance, presentation or transfer of stock; the genuineness of endorsements; the authority of presenters; or the collection or payment of charges or taxes incident to the issuance or transfer of stock. AST may, however, delay or decline an issuance or transfer if it deems it to be in its or a Fund’s best interests to receive evidence or assurance of such validity, authority, collection or payment. AST shall not be responsible for any discrepancies in its records or between its records and those of a Fund, if it is a successor transfer agent or successor registrar, unless no discrepancy existed in the records of such Fund and any predecessor transfer agent or predecessor registrar. AST shall not be deemed to have notice of, or be required to inquire regarding, any provision of a Fund’s declaration of trust or by-laws, any court or administrative order, or any other document, unless it is specifically advised of such in a writing from such Fund, which writing shall set forth the manner in which it affects the Shares. In no event shall AST be responsible for any transfer or issuance not affected by it.

12.    Limitations on Liability. In no event shall any party hereto have any liability for any incidental, special, statutory, indirect or consequential damages, or for any loss of profits, revenue, data or cost of cover; provided, however, that the foregoing shall not limit the indemnification obligations of the Funds or AST hereunder with respect to any third-party claims. Neither parties’ liability arising out of or in connection with this Agreement shall exceed the aggregate amount of all fees (excluding expenses) paid under this Agreement (or the Sub-Transfer Agency and Registrar Services Agreement by and between Pioneer Investment Management Shareholder Services, Inc. and AST with respect to the Funds) in the twelve (12) month period immediately preceding the date of the first event giving rise to liability; provided, however, that the foregoing shall not limit the indemnification obligations of the Funds hereunder with respect to any third-party claims.

13.    Indemnities. (a) From and at all times after the date of this Agreement, each Fund severally covenants and agrees to defend, indemnify, reimburse and hold harmless AST and its officers, directors, employees, affiliates and agents (each, an “AST Indemnified Party”) against any actions, claims, losses, liability or reasonable expenses (including legal and other fees and expenses) (collectively, “Losses”) incurred by or asserted against any AST Indemnified Party arising out of or in connection with entering into this Agreement, the performance of AST’s duties thereunder, or the enforcement of the indemnity under this clause (a) except for such losses, liabilities or expenses incurred as a result of an AST Indemnified Party’s sole negligence, bad faith or willful misconduct. No Fund shall be liable under this indemnity with respect to any claim

5

against an AST Indemnified Party unless the Fund is notified of the written assertion of such a claim, or of any action commenced against an AST Indemnified Party, promptly after AST shall have received any such written information as to the nature and basis of the claim; provided, however, that failure by AST to provide such notice shall not relieve a Fund of any liability hereunder if no prejudice occurs.

(b) No Fund shall be responsible for, and, subject to Section 12, AST shall indemnify and hold each Fund harmless from and against, any and all Losses arising out of or attributable to the sole negligence, bad faith or willful misconduct of AST (or any of its agents or subcontractors) in the performance of its duties hereunder or the enforcement of the indemnity under this clause (b).

(c) All provisions regarding indemnification, liability and limits thereon shall survive the termination of this Agreement.

14.    Force Majeure. AST is not liable for failure or delay in the performance of its obligations under this Agreement if such failure or delay is due to causes beyond its reasonable control, including but not limited to Acts of God (including fire, flood, earthquake, storm, hurricane or other natural disaster), war, invasion, act of foreign enemies, hostilities (regardless of whether war is declared), civil war, rebellion, revolution, insurrection, military or usurped power or confiscation, terrorist activities, nationalization, government sanction, blockage, embargo, labor dispute, strike, lockout or interruption or failure of electricity or telephone service or any other force majeure event. No Fund is entitled to terminate this Agreement under Section 6 (Performance of Services) in such circumstances.

15.    No Third Party Beneficiaries. The provisions of this Agreement are intended to benefit only AST and each Fund and their respective successors and assigns. No rights shall be granted to any other person by virtue of this Agreement, and there are no third party beneficiaries of this Agreement.

16.    Governing Law. This Agreement shall be construed and interpreted in accordance with the internal laws of the State of New York, without giving effect to the conflict of laws principles thereof.

Any final judgment shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Any of these courts shall be proper venue for any such lawsuit or judicial proceeding and the parties hereto waive any objection to such venue and irrevocably and unconditionally waive and agree not to plead or claim in any such court that any such suit or proceeding in any such court has been brought in an inconvenient forum.
