Amendment to FATCA Support Services Agreement

EXHIBIT A

FATCA SERVICES

1.)    FATCA Support Services – FFI Registration Assistance

• The Services Provider will assist the Fund in registering as an FFI with the IRS for the purpose of obtaining a Global Intermediary Identification Number (“GIIN”), using either the electronic process (the “IRS Registration System”) or the paper process (“Form 8957”), as agreed with the Fund. The IRS has stated their preference for electronic registration using the IRS Registration System.

• The Fund shall confirm to the Services Provider which of their FFIs are to be registered with the IRS. Where electronic registrations are to be submitted, the Fund or the Services Provider will, as agreed, establish an online account on the IRS Registration System (the “Online Account”).

• The Services Provider will source and collate responses to the IRS Registration System form based upon information and documentation readily available and in its possession and, subject to the agreement of the Services Provider, any additional or updated information provided to the Services Provider by the Fund or its agents at the time of registration (all such information and documentation, collectively, the “Registration Information”) in accordance with the IRS Registration System form (the “IRS Instructions”) and with the agreed FATCA Procedures. It will be agreed that the Services Provider must be designated as a Point of Contact (“PoC”).

• The Services Provider will use the IRS Registration System to input the Registration Information for the FFI and will check completeness of the relevant questions prior to notifying the Fund that all of the responses have been input.

• The Fund will review, validate and approve the Registration Information input by the Services Provider, and complete the registration process with the IRS by either (i) completing Part 4 of the online registration process, electronically signing and submitting to the IRS via the “IRS Registration System” or (ii) completing Part 4 on Form “8957” and submitting to the IRS by post, as applicable.

• The Fund will receive notification of the GIIN direct from the IRS by either (i) an email sent to the email address specified at the time of establishing the Online Account or (ii) an electronically available confirmation from the IRS in respect of registrations completed using Form 8957.

• The Fund will notify the Services Provider of the GIIN for each FFI registered under this service.

• The Fund will retain full responsibility for maintaining the information contained within the Online Account and for monitoring any notifications received from the IRS via the Online Account.

2.)    FATCA Support Services – Annual Reporting

• For each Fund the Services Provider will compile FATCA reports and any additional reporting required in the Fund’s domicile in connection with the FATCA-like intergovernmental agreements signed in 2013 between the United Kingdom and its Crown Dependencies and Overseas Territories and applicable guidance (“UK CDOT”), in each case as is required by the IRS or other tax authorities (the “Annual Reporting”) based upon the information derived from the contracted services performed by the Services Provider and stored in its transfer agency Platform.

A-1

• The Services Provider will provide the Fund, or on the Fund’s behalf will provide to affected Investors in the Fund (subject to the Fund’s approval), information related to the investor specific reporting to be provided by the Fund to relevant tax authorities as part of the Annual Reporting.

• The Services Provider will provide the Fund with the Annual Reporting at a time or times and in a format as described in the agreed FATCA Procedures.
