4. Instructions. Unless otherwise explicitly indicated herein, the Custodian shall perform its duties pursuant to Instructions. As used herein, the term Instruction shall mean a directive initiated by the Fund and/or the General Partner, acting directly or through its board of directors, officers or other Authorized Persons, which directive shall conform to the requirements of this Section 4.

4.1 Authorized Persons. For purposes hereof, an Authorized Person shall be a person or entity authorized to give Instructions for or on behalf of the Fund and/or the General Partner by written notices to the Custodian or otherwise in accordance with procedures delivered to and acknowledged by the Custodian, including without limitation the Fund’s Investment Advisor (as defined in Section 13). The Custodian may treat any Authorized Person as having full authority of the Fund and/or the General Partner to issue Instructions hereunder unless the notice of authorization contains explicit limitations as to said authority. The Custodian shall be entitled to rely upon the authority of Authorized Persons until it receives appropriate written notice from the Fund to the contrary.

The Fund hereby designates the Marketing Agent (as such term is defined under an Authorized Purchaser Agreement entered into by the General Partner on behalf of the Fund, as approved by the Custodian (the Authorized Purchaser Agreement)) as an Authorized Person from whom the Custodian is hereby authorized to receive Instructions to accept deposits of cash and securities in connection with the purchase of Units (as such term is defined under the Authorized Purchaser Agreement) and the distribution of cash and securities in connection with the redemption of Units.

4.2 Form of Instruction. Each Instruction shall be transmitted by such secured or authenticated electro-mechanical means as the Custodian shall make available to the Fund from time to time unless the Fund and/or the General Partner shall elect to transmit such Instruction in accordance with Subsections 4.2.1 through 4.2.3 of this Section.

4.2.1 Fund Designated Secured-Transmission Method. Instructions may be transmitted through a secured or tested electro-mechanical means identified by the Fund, the General Partner or by an Authorized Person entitled to give Instructions and acknowledged and accepted by the Custodian; it being understood that such acknowledgment shall authorize the Custodian to receive and process such means of delivery but shall not represent a judgment by the Custodian as to the reasonableness or security of the method determined by the Authorized Person.

4.2.2 Written Instructions. Instructions may be transmitted in a writing that bears the manual signature of Authorized Persons.

4.2.3 Other Forms of Instruction. Instructions may also be transmitted by another means determined by the Fund, the General Partner or Authorized Persons and acknowledged and accepted by the Custodian (subject to the same limits as to acknowledgements as is contained in Subsection 4.2.1, above) including Instructions given orally or by SWIFT, telex or telefax (whether tested or untested).

When an Instruction is given by means established under Subsections 4.2.1 through 4.2.3, it shall be the responsibility of the Custodian to use reasonable care to adhere to any security or other procedures established in writing between the Custodian and the Authorized Person with respect to such means of Instruction, but such Authorized Person shall be solely responsible for determining that the particular means chosen is reasonable under the circumstances. Oral Instructions shall be binding upon the Custodian only if and when the Custodian takes action with respect thereto. With respect to telefax instructions, the parties agree and acknowledge that receipt of legible instructions cannot be assured, that the Custodian cannot verify that authorized signatures on telefax instructions are original or properly affixed, and that the Custodian shall not be liable for losses or expenses incurred through actions taken in reliance on inaccurately stated, illegible or unauthorized telefax instructions. The provisions of Section 4A of the Uniform Commercial Code as currently in effect in the State of New York shall apply to the Fund’s transfers performed in accordance with Instructions. The Funds Transfer Services Schedule (as defined in Section 13) and the Electronic and Online Services Schedule to this Agreement shall each comprise a designation of form of a means of delivering Instructions for purposes of this Section 4.2.

4.3 Completeness and Contents of Instructions. The Authorized Person shall be responsible for assuring the adequacy and accuracy of Instructions. Particularly, upon any acquisition or disposition or other dealing in the Fund’s Investments and upon any delivery and transfer of any Investment or moneys, the person initiating such Instruction shall give the Custodian an Instruction with appropriate detail, including, without limitation:

4.3.1 The transaction date and the date and location of settlement;

4.3.2 The specification of the type of transaction;

4.3.3 A description of the Investments or moneys in question, including, as appropriate, quantity, price per unit, amount of money to be received or delivered and currency information. Where an Instruction is communicated by electronic means, or otherwise where an Instruction contains an identifying number such as a CUSIP, SEDOL or ISIN number, the Custodian shall be entitled to rely on such number as controlling notwithstanding any inconsistency contained in such Instruction, particularly with respect to the Investment description; and

4.3.4 The name of the broker or similar entity concerned with execution of the transaction.

If the Custodian shall determine that an Instruction is either unclear or incomplete, the Custodian may give prompt notice of such determination to the Fund and/or the General Partner, and the Fund and/or the General Partner shall thereupon amend or otherwise reform such Instruction. In such event, the Custodian shall have no obligation to take any action in response to the Instruction initially delivered until the redelivery of an amended or reformed Instruction.

4.4 Timeliness of Instructions. In giving an Instruction, the Fund and/or the General Partner shall take into consideration delays which may occur due to the involvement of a Subcustodian or agent, differences in time zones, and other factors particular to a given market, exchange or issuer. When the Custodian has established specific timing requirements or deadlines with respect to particular classes of Instruction, or when an Instruction is received by the Custodian at such a time that it could not reasonably be expected to have acted on such Instruction due to time zone differences or other factors beyond its reasonable control, the execution of any Instruction received by the Custodian after such deadline or at such time (including any modification or revocation of a previous Instruction) shall be at the risk of the Fund.

5. Safekeeping of Fund Assets. The Custodian shall hold Investments delivered to it or Subcustodians for the Fund in accordance with the provisions of this Section. The Custodian shall not be responsible for (a) the safekeeping of Investments not delivered or that are not caused to be issued to it or its Subcustodians; (b) pre-existing faults or defects in Investments that are delivered to the Custodian or its Subcustodians; or (c) the safekeeping of Natural Gas Interests and Natural Gas Forward Contracts (each as defined in the Fund’s prospectus). The Custodian is hereby authorized to hold with itself or a Subcustodian, and to record in one or more accounts, all Investments delivered to and accepted by the Custodian, any Subcustodian or their respective agents pursuant to an Instruction or in consequence of any corporate action. The Custodian shall hold Investments for the account of the Fund and shall segregate Investments from assets belonging to the Custodian and shall cause its Subcustodians to segregate Investments from assets belonging to the Subcustodian in an account held for the Fund or in an account maintained by the Subcustodian generally for non-proprietary assets of the Custodian.

5.1 Use of Securities Depositories. The Custodian may deposit and maintain Investments in any Securities Depository (as defined in Section 13), either directly or through one or more Subcustodians appointed by the Custodian. Investments held in a Securities Depository shall be held (a) subject to the agreement, rules, statement of terms and conditions or other document or conditions effective between the Securities Depository and the Custodian or the Subcustodian, as the case may be, and (b) in an account for the Fund or in bulk segregation in an account maintained for the non-proprietary assets of the entity holding such Investments in the Securities Depository. If market practice or the rules and regulations of the Securities Depository prevent the Custodian, the Subcustodian or any agent of either from holding its client assets in such a separate account, the Custodian, the Subcustodian or other agent shall as appropriate segregate such Investments for benefit of the Fund or for the benefit of clients of the Custodian generally on its own books.

5.2 Certificated Assets. Investments which are certificated may be held in registered or bearer form: (a) in the Custodian’s vault; (b) in the vault of a Subcustodian or agent of the Custodian or a Subcustodian; or (c) in an account maintained by the Custodian, Subcustodian or agent at a Securities Depository; all in accordance with customary market practice in the jurisdiction in which any Investments are held.

5.3 Registered Assets. Investments which are registered may be registered in the name of the Custodian, a Subcustodian, or in the name of the Fund or a nominee for any of the foregoing, and may be held in any manner set forth in Section 5.2 above with or without any identification of fiduciary capacity in such registration.

5.4 Book Entry Assets. Investments which are represented by book-entry may be so held in an account maintained by the Book-entry Agent (as defined in Section 13) on behalf of the Custodian, a Subcustodian or another agent of the Custodian, or a Securities Depository.

5.5 Replacement of Lost Investments. In the event of a loss of Investments for which the Custodian is responsible under the terms of this Agreement, the Custodian shall replace such Investment, or in the event that such replacement cannot be effected, the Custodian shall pay to the Fund the fair market value of such Investment based on the last available price as of the close of business in the relevant market on the date that a claim was first made to the Custodian with respect to such loss, or, if less, such other amount as shall be agreed by the parties as the date for settlement.

6. Administrative Duties of the Custodian. The Custodian shall perform the following administrative duties with respect to Investments of the Fund.

6.1 Purchase of Investments. Pursuant to Instructions, Investments purchased for the account of the Fund shall be paid for (a) against delivery thereof to the Custodian or a Subcustodian, as the case may be, either directly or through a Clearing Corporation (as defined in Section 13) or a Securities Depository (in accordance with the rules of such Securities Depository or such Clearing Corporation), or (b) otherwise in accordance with an Instruction, Applicable Law, generally accepted trade practices, or the terms of the instrument representing such Investment.

6.2 Sale of Investments. Pursuant to Instructions, Investments sold for the account of the Fund shall be delivered (a) against payment therefor in cash, by check or by bank wire transfer, (b) by credit to the account of the Custodian or the applicable Subcustodian, as the case may be, with a Clearing Corporation or a Securities Depository (in accordance with the rules of such Securities Depository or such Clearing Corporation), or (c) otherwise in accordance with an Instruction, Applicable Law, generally accepted trade practices, or the terms of the instrument representing such Investment.

6.3 Delivery and Receipt in Connection with Borrowings of the Fund or other Collateral and Margin Requirements. Pursuant to Instructions and subject to the last sentence in Section 6.4 below, the Custodian may deliver or receive Investments or cash of the Fund in connection with borrowings or loans by the Fund and other collateral and margin requirements.

6.4 Futures and Over-the-Counter (OTC) Contracts. If, pursuant to an Instruction, the Custodian shall become a party to an agreement with the Fund and a futures commission merchant regarding margin or a counterparty to an OTC contract (Tri-Party Agreement), the Custodian shall (a) receive and retain, to the extent the same is provided to the Custodian, confirmations or other documents evidencing the purchase or sale by the Fund of exchange-traded futures contracts or the entering into of an option, forward or other derivatives transaction by the Fund; (b) when required by such Tri-Party Agreement, deposit and maintain in an account opened pursuant to such Agreement (Margin Account) segregated either physically or by book-entry in a Securities Depository for the benefit of any futures commission merchant, such Investments as the Fund shall have designated as initial, maintenance or variation “margin” deposits or other collateral intended to secure the Fund’s performance of its obligations under the terms of any exchange-traded futures contracts and commodity options; and (c) thereafter pay, release or transfer Investments into or out of the Margin Account in accordance with the provisions of such Tri-Party Agreement. Alternatively, the Custodian may deliver Investments, in accordance with an Instruction, to a futures commission merchant for margin purposes or to the counterparty or its custodian.

In addition, the Custodian shall not be required to transfer margin or any other assets of the Fund to a Margin Account if at the time of such request, such transfer would reduce the aggregate market value of all unencumbered securities, cash, cash equivalents and other unencumbered liquid assets of the Fund in the custody of the Custodian to less than ten (10) percent of the then current net asset value of the Fund.

6.5 Contractual Obligations and Similar Investments. From time to time, the Fund’s Investments may include Investments that are not ownership interests as may be represented by certificate (whether registered or bearer), by entry in a Securities Depository or by book entry agent, registrar or similar agent for recording ownership interests in the relevant Investment. If the Fund shall at any time acquire such Investments, including without limitation deposit obligations, loan participations, repurchase agreements and derivative arrangements, the Custodian shall (a) receive and retain, to the extent the same are provided to the Custodian, confirmations or other documents evidencing the arrangement; and (b) perform on the Fund’s account in accordance with the terms of the applicable arrangement, but only to the extent directed to do so by an Instruction. The Custodian shall have no responsibility for agreements running to the Fund as to which it is not a party other than to retain, to the extent the same are provided to the Custodian, documents or copies of documents evidencing the arrangement and, in accordance with an Instruction, to include such arrangements in reports made to the Fund.

The Custodian is hereby authorized to endorse and deliver any instrument required to be so endorsed and delivered to effect collection of any amount due and payable to the Fund with respect to Investments.

6.11 Ownership Certificates and Disclosure of the Fund’s Interest.

With respect to securities issued outside of the United States of America, information shall be released in accordance with law or custom of the particular country in which such security is located.

The Custodian shall attend to all nondiscretionary details in connection with the sale or purchase or other administration of Investments, except as otherwise directed by an Instruction, and may make payments to itself or others for minor expenses of administering Investments under this Agreement; provided that the Fund shall have the right to request an accounting with respect to such expenses.

In fulfilling the duties set forth in Sections 6.6 through 6.10 above, the Custodian shall provide to the Fund all material information pertaining to a corporate action which the Custodian actually receives; provided that the Custodian shall not be responsible for the completeness or accuracy of such information. Information relative to any pending corporate action made available to the Fund via any of the services described in the Electronic and Online Services Schedule shall constitute the delivery of such information by the Custodian hereunder.

The Custodian may at any time or times in its discretion appoint (and may at any time remove) agents (other than Subcustodians) to carry out some or all of the administrative provisions of this Agreement (Agents), provided, however, that the appointment of such agent shall not relieve the Custodian of its administrative obligations under this Agreement.

7. Cash Accounts, Deposits and Money Movements. Subject to the terms and conditions set forth in this Section 7, the Fund and the General Partner each hereby authorizes the Custodian to open and maintain, with itself or with Subcustodians, cash accounts in United States Dollars, in such other currencies as are the currencies of the countries in which the Fund maintains Investments or in such other currencies as the Fund shall from time to time request by Instruction.

7.1 Types of Cash Accounts. Cash accounts opened on the books of the Custodian (Principal Accounts) shall be opened in the name of the Fund. Such accounts collectively shall be a deposit obligation of the Custodian and shall be subject to the terms of this Section 7 and the general liability provisions contained in Section 9. Cash accounts opened on the books of a Subcustodian may be opened in the name of the Fund or the Custodian or in the name of the Custodian for its customers generally (Agency Accounts). Such deposits shall be obligations of the Subcustodian and shall be treated as an Investment of the Fund. Accordingly, the Custodian shall be responsible for exercising reasonable care in the administration of such accounts but shall not be liable for their repayment in the event such Subcustodian, by reason of its bankruptcy, insolvency or otherwise, fails to make repayment.

7.2 Payments and Credits with Respect to the Cash Accounts. The Custodian shall make payments from or deposits to any of said accounts in the course of carrying out its administrative duties, including but not limited to income collection with respect to the Fund’s Investments, and otherwise in accordance with Instructions. The Custodian and its Subcustodians shall be required to credit amounts to the cash accounts only when moneys are actually received in cleared funds in accordance with banking practice in the country and currency of deposit. Any credit made to any Principal or Agency Account before actual receipt of cleared funds shall be provisional and may be reversed by the Custodian in the event such payment is not actually collected. Unless otherwise specifically agreed in writing by the Custodian or any Subcustodian, all deposits shall be payable only at the branch of the Custodian or Subcustodian where the deposit is made or carried.

7.3 Currency and Related Risks. The Fund and the General Partner each bears risks of holding or transacting in any currency, including any xxxx to market exposure associated with a foreign exchange transaction undertaken with the Custodian. The Custodian shall not be liable for any loss or damage arising from the applicability of any law or regulation now or hereafter in effect, or from the occurrence of any event, which may delay or affect the transferability, convertibility or availability of any currency in the country (a) in which such Principal or Agency Accounts are maintained or (b) in which such currency is issued, and in no event shall the Custodian be obligated to make payment of a deposit denominated in a currency during the period during which its transferability, convertibility or availability has been affected by any such law, regulation or event. Without limiting the generality of the foregoing, neither the Custodian nor any Subcustodian shall be required to repay any deposit made at a foreign branch of either the Custodian or Subcustodian if such branch cannot repay the deposit due to a cause for which the Custodian would not be responsible in accordance with the terms of Section 9 of this Agreement unless the Custodian or such Subcustodian expressly agrees in writing to repay the deposit under such circumstances. All currency transactions in any account opened pursuant to this Agreement are subject to exchange control regulations of the United States and of the country where such currency is the lawful currency or where the account is maintained. Any taxes, costs, charges or fees imposed on the convertibility of a currency held by the Fund shall be for the account of the Fund.

7.4 Foreign Exchange Transactions. The Custodian shall, subject to the terms of this Section, settle foreign exchange transactions (including contracts, futures, options and options on futures) on behalf and for the account of the Fund with such currency brokers or banking institutions, including Subcustodians, as the Fund may direct pursuant to Instructions. The Custodian may act as principal in any foreign exchange transaction with the Fund in accordance with Section 7.4.2 of this Agreement. The obligations of the Custodian in respect of all foreign exchange transactions (whether or not the Custodian shall act as principal in such transaction) shall be contingent on the free, unencumbered transferability of the currency transacted on the actual settlement date of the transaction.

7.4.1 Third Party Foreign Exchange Transactions. The Custodian shall process foreign exchange transactions (including without limitation contracts, futures, options, and options on futures), where any third party acts as principal counterparty to the Fund on the same basis it performs duties as agent for the Fund with respect to any other of the Fund’s Investments. Accordingly, the Custodian shall only be responsible for delivering or receiving currency on behalf of the Fund in respect of such contracts pursuant to Instructions. The Custodian shall not be responsible for the failure of any counterparty (including any Subcustodian) in such agency transaction to perform its obligations thereunder. The Custodian (a) shall transmit cash and Instructions to and from the currency broker or banking institution with which a foreign exchange contract or option has been executed pursuant hereto, (b) may make free outgoing payments of cash in the form of United States Dollars or foreign currency without receiving confirmation of a foreign exchange contract or option or confirmation that the countervalue currency completing the foreign exchange contract has been delivered or received or that the option has been delivered or received, and (c) shall hold all confirmations, certificates and other documents and agreements received by the Custodian and evidencing or relating to such foreign exchange transactions in safekeeping. The Fund accepts full responsibility for its use of third-party foreign exchange dealers and for execution of said foreign exchange contracts and options and understands that the Fund shall be responsible for any and all costs and interest charges which may be incurred by the Fund or the Custodian as a result of the failure or delay of third parties to deliver foreign exchange.

7.4.2 Foreign Exchange with the Custodian as Principal. The Custodian may as principal undertake foreign exchange transactions with the Fund as the Custodian and the Fund may agree from time to time. In such event, the foreign exchange transaction will be performed in accordance with the particular agreement of the parties, or in the event a principal foreign exchange transaction is initiated by an Instruction in the absence of specific agreement, such transaction will be performed in accordance with the usual commercial terms of the Custodian. In the event that the Fund defaults on the settlement of any such foreign exchange transaction with the Custodian, the Fund shall be liable for contracted currency of the transaction together with any xxxx to market exposure associated with the replacement purchase of the contracted currency undertaken with the Custodian.

7.5 Delays. If no event of Force Majeure shall have occurred and be continuing and in the event that a delay shall have been caused by the negligence or willful misconduct of the Custodian in carrying out an Instruction to credit or transfer cash, the Custodian shall be liable to the Fund: (a) with respect to Principal Accounts, for interest to be calculated at the rate customarily paid on such deposit and currency by the Custodian on overnight deposits at the time the delay occurs for the period from the day when the transfer should have been effected until the day it is in fact effected; and, (b) with respect to Agency Accounts, for interest to be calculated at the rate customarily paid on such deposit and currency by the Subcustodian on overnight deposits at the time the delay occurs for the period from the day when the transfer should have been effected until the day it is in fact effected. The Custodian shall not be liable for delays in carrying out such Instructions to transfer cash which are not due to the Custodian’s own negligence or willful misconduct.

7.6 Advances. If, for any reason in connection with this Agreement the Custodian or any Subcustodian makes an Advance to facilitate settlement or otherwise for the benefit of the Fund (whether or not any Principal or Agency Account shall be overdrawn either during, or at the end of, any Business Day (defined as any day other than a day on which the NYSE Arca, Inc., the New York Mercantile Exchange or the New York Stock Exchange is closed for regular trading)), the Fund and the General Partner each hereby does:

7.6.1 acknowledge that the Fund shall have no right, title or interest in or to any Investments purchased with such Advance or proceeds of such Investments, and that any credit to an account of Fund shall be provisional, until: (a) the debit of the Principal or Agency Account by Custodian for an amount equal to Advance Costs; and/or (b) if such debit produces an overdraft in such account, reimbursement to the Custodian or Subcustodian for the amount of such overdraft;

7.6.2 acknowledge that the Custodian has an automatically perfected statutory security interest in Investments purchased with any such Advance (as defined in Section 13) pursuant to Section 9-206 of the Uniform Commercial Code as in effect in the State of New York from time to time;

7.6.3 in addition, in order to secure the obligations of the Fund to pay or perform any and all obligations of the Fund pursuant to this Agreement, including without limitation to repay any Advance made pursuant to this Agreement, grant to the Custodian a security interest in all Investments and proceeds thereof (as defined in the Uniform Commercial Code as currently in effect in the State of New York); and agree to take, and agree that the Custodian may take, in respect of the security interest referenced above, any further actions that the Custodian may reasonably require.

7.7 Custodian’s Rights Neither the Custodian nor any Subcustodian shall be obligated to make any Advance or to allow an Advance to occur to the Fund, and in the event that the Custodian or any Subcustodian does make or allow an Advance, any such Advance and any transaction giving rise to such Advance shall be for the account and risk of the Fund and shall not be deemed to be a transaction undertaken by the Custodian for its own account and risk. If such Advance shall have been made or allowed by a Subcustodian or any other person, the Custodian may assign all or part of its security interest referenced above and any other rights granted to the Custodian hereunder to such Subcustodian or other person. If the Fund shall fail to repay the Advance Costs when due, the Custodian or its assignee, as the case may be, shall be entitled to a portion of the available cash balance in any Agency or Principal Account equal to such Advance Costs, and the Fund authorizes the Custodian, on behalf of the Fund, to pay an amount equal to such Advance Costs irrevocably to such Subcustodian or other person, and to dispose of any property in such Account to the extent necessary to make such payment. Any Investments and funds credited to accounts subject to this Agreement created pursuant hereto shall be treated as financial assets credited to securities accounts under Articles 8 and 9 of the Uniform Commercial Code as in effect in the State of New York from time to time. Accordingly, the Custodian and any Subcustodian shall have the rights and benefits of a secured creditor that is a securities intermediary under such Articles 8 and 9.

7.8 Integrated Account. For purposes hereof, deposits maintained in all Principal Accounts (whether or not denominated in United States Dollars) shall collectively constitute a single and indivisible current account with respect to the Fund’s obligations to the Custodian or its assignee, and balances in the Principal Accounts shall be available for satisfaction of the Fund’s obligations under this Section 7. The Custodian shall further have a right of offset against the balances in any Agency Account maintained hereunder to the extent that the aggregate of all Principal Accounts is overdrawn.

(the Custodian) is hereby instructed by United States 12 Month Natural Gas Fund, LP (the Fund) and United States Commodity Funds LLC (the General Partner) to execute each payment order, whether denominated in United States Dollars or other applicable currencies, received by the Custodian in the Fund’s name as sender and authorized and confirmed by an Authorized Person as defined in a Custodian Agreement dated as of November 3, 2009 by and among the Custodian, the General Partner and the Fund, as amended or restated from time thereafter (the Agreement), provided that the Fund has sufficient available funds on deposit in a Principal Account as defined in the Agreement and provided that the order (i) is received by the Custodian in the manner specified in this Funds Transfer Services Schedule or any amendment hereafter; (ii) complies with any written instructions and restrictions of the Fund as set forth in this Funds Transfer Services Schedule or any amendment hereafter; (iii) is authorized by the Fund or is verified by the Custodian in compliance with a security procedure set forth in Paragraph 2 below for verifying the authenticity of a funds transfer communication sent to the Custodian in the name of the Fund or for the detection of errors set forth in any such communication; and (iv) contains sufficient data to enable the Custodian to process such transfer.

2. Security Procedure. The Fund and the General Partner hereby elect to use the procedure selected below as its security procedure (the Security Procedure). The Security Procedure will be used by the Custodian to verify the authenticity of a payment order or a communication amending or canceling a payment order. The Custodian will act on instructions received provided the instruction is authenticated by the Security Procedure. The Fund and the General Partner agree and acknowledge in connection with (i) the size, type and frequency of payment orders normally issued or expected to be issued by the Fund to the Custodian, (ii) all of the security procedures offered to the Fund and the General Partner by the Custodian, and (iii) the usual security procedures used by customers and receiving banks similarly situated, that authentication through the Security Procedure shall be deemed commercially reasonable for the authentication of all payment orders submitted to the Custodian. The Fund and the General Partner hereby elect (please choose one) the following Security Procedure as described below:

BIDS and BIDS Worldview Payment Products. BIDS and BIDS Worldview Payment Products, are on-line payment order authorization facilities with built-in authentication procedures. The Custodian, the General Partner and the Fund shall each be responsible for maintaining the confidentiality of passwords or other codes to be used by them in connection with BIDS. The Custodian will act on instructions received through BIDS without duty of further confirmation unless the Fund and/or the General Partner notifies the Custodian that its password is not secure.

SWIFT. The Custodian, the General Partner and the Fund shall comply with SWIFT’s authentication procedures. The Custodian will act on instructions received via SWIFT provided the instruction is authenticated by the SWIFT system.

Tested Telex. The Custodian will accept payment orders sent by tested telex, provided the test key matches the algorithmic key the Custodian, the General Partner and Fund have agreed to use.

Computer Transmission. The Custodian is able to accept transmissions sent from the Fund’s and/or the General Partner’s computer facilities to the Custodian’s computer facilities provided such transmissions are encrypted and digitally certified or are otherwise authenticated in a reasonable manner based on available technology. Such procedures shall be established in an operating protocol among the Custodian, the General Partner and the Fund.

Telefax Instructions. A payment order transmitted to the Custodian by telefax transmission shall be transmitted by the Fund and/or the General Partner to a telephone number specified from time to time by the Custodian for such purposes. If it detects no discrepancies, the Custodian will then either:

if the telefax requests a repetitive payment order, the Custodian may call the Fund and/or the General Partner at its last known telephone number, request to speak to the Fund, the General Partner or Authorized Person, and confirm the authorization and details of the payment order (a Callback); or

if the telefax requests a non-repetitive order, the Custodian will perform a Callback.

All faxes must be accompanied by a fax cover sheet which indicates the sender’s name, Fund name, telephone number, fax number, number of pages, and number of transactions or instructions attached.

¨ Telephonic. A telephonic payment order shall be called into the Custodian at the telephone number designated from time to time by the Custodian for that purpose. The caller shall identify herself/himself as an Authorized Person. The Custodian shall obtain the payment order data from the caller. The Custodian shall then:

if a telephonic repetitive payment order, the Custodian may perform a Callback; or

if a telephonic non-repetitive payment order, the Custodian will perform a Callback.

In the event the Fund and the General Partner choose a procedure which is not a Security Procedure as described above, the Fund and the General Partner agree to be bound by any payment order (whether or not authorized) issued in their name and accepted by the Custodian in compliance with the procedure selected by the Fund and the General Partner.

3. Rejection of Payment Orders. The Custodian shall give the Fund and the General Partner timely notice of the Custodian’s rejection of a payment order. Such notice may be given in writing or orally by telephone, each of which is hereby deemed commercially reasonable. In the event the Custodian fails to execute a properly executable payment order and fails to give the Fund and/or the General Partner notice of the Custodian’s non-execution, the Custodian shall be liable only for the Fund’s actual damages and only to the extent that such damages are recoverable under UCC 4A (as defined in Paragraph 7 below). Notwithstanding anything in this Funds Transfer Services Schedule and the Agreement to the contrary, the Custodian shall in no event be liable for any consequential or special damages under this Funds Transfer Services Schedule, whether or not such damages relate to services covered by UCC 4A, even if the Custodian has been advised of the possibility of such damages. Whenever compensation in the form of interest is payable by the Custodian to the Fund pursuant to this Funds Transfer Services Schedule, such compensation will be payable in accordance with UCC 4A.

4. Cancellation of Payment Orders. The Fund or the General Partner may cancel a payment order but the Custodian shall have no liability for the Custodian’s failure to act on a cancellation instruction unless the Custodian has received such cancellation instruction at a time and in a manner affording the Custodian reasonable opportunity to act prior to the Custodian’s execution of the order. Any cancellation shall be sent and confirmed in the manner set forth in Paragraph 2 above.

5. Responsibility for the Detection of Errors and Unauthorized Payment Orders. Except as may be provided in the Agreement, the Custodian is not responsible for detecting any Fund or General Partner error contained in any payment order sent by the Fund or the General Partner to the Custodian. In the event that the Fund’s or the General Partner’s payment order to the Custodian either (i) identifies the beneficiary by both a name and an identifying or bank account number and the name and number identify different persons or entities, or (ii) identifies any bank by both a name and an identifying number and the number identifies a person or entity different from the bank identified by name, execution of the payment order, payment to the beneficiary, cancellation of the payment order or actions taken by any bank in respect of such payment order may be made solely on the basis of the number. The Custodian shall not be liable for interest on the amount of any payment order that was not authorized or was erroneously executed unless the Fund and/or the General Partner so notifies the Custodian within thirty (30) Business Days following the Fund’s and/or the General Partner’s receipt of notice that such payment order had been processed. If a payment order in the name of the Fund and accepted by the Custodian was not authorized by the Fund or the General Partner, the liability of the parties will be governed by the applicable provisions of UCC 4A.

6. Laws and Regulations. The rights and obligations of the Custodian, the General Partner and the Fund with respect to any payment order executed pursuant to this Funds Transfer Services Schedule will be governed by any applicable laws, regulations, circulars and funds transfer system rules, the laws and regulations of the United States of America and of other relevant countries including exchange control regulations and limitations on dealings or other sanctions, and including without limitation those sanctions imposed under the law of the United States of America by the Office of Foreign Assets Control. Any taxes, fines, costs, charges or fees imposed by relevant authorities on such transactions shall be for the account of the Fund.
