CAMPBELL STRATEGIC ALLOCATION FUND L.P.
GLOBAL INSTITUTIONAL
MASTER CUSTODY AGREEMENT
(limited partnership)

     THIS AGREEMENT, effective as of the 8^st day of July, 2009, is made between CAMPBELL STRATEGIC ALLOCATION FUND L.P. , a limited partnership organized and existing under the laws of Delaware (the “Partnership”), and THE NORTHERN TRUST COMPANY, an Illinois corporation, of Chicago, Illinois (“Northern”).

     The Partnership hereby appoints Northern as its agent to establish and maintain a custody account in the name of the Partnership (the “Account”) and to hold in such Account those assets of the Partnership as are transferred to it from time to time.

     The Partnership shall direct Northern to establish one or more separate accounts (“Separate Account”) for cash, securities and other property of the Account received by Northern from time to time. Each Separate Account shall be managed by either the Partnership or an investment manager appointed by the Partnership. By written direction the Partnership will designate assets of the Account to be allocated to each Separate Account and direct Northern to transfer assets of the Account to or from each Separate Account. With respect to cash deposited in Northern’s banking department, the Separate Accounts are maintained as a matter of convenience and, therefore, Northern may aggregate the Separate Accounts for purposes of its depository requirements. All assets, other than cash, will be maintained by Northern in segregated accounts and accounted for separately from Northen’s own assets.

     Unless directed otherwise in writing by the Partnership, Northern shall have with respect to the Account the powers and duties as hereinafter provided, except that no such direction shall change Northern’s powers and duties hereunder without Northern’s consent.

     Northern and the Partnership agree as follows:

     1. Northern shall hold and safeguard the cash, securities, and other property in the Account and shall collect the income and principal thereof when due.

     2. Northern may hold securities or other property of each Separate Account through an agent or in the name of its nominee or in a corporate depository or federal book entry account system or other form as it deems best. All securities held directly or indirectly in the Account shall be segregated on Northern’s books and records from Northern’s own assets and the assets of other Northern clients, and shall be held by Northern for the exclusive account and benefit of the Partnership, and beneficial ownership of the securities shall at all times remain vested in the Partnership; the books and records of Northern shall so identify the securities and the Account. Northern shall forward any proxies relating to securities or other property held in the Account to the appropriate investment manager, or, in accounts where no investment manager has been appointed, to

the Partnership or the Partnership’s designee, and Northern shall process such proxies as directed by the investment manager, Partnership, or the Partnership’s designee.

     3. With respect to a Separate Account managed by the Partnership, all security transactions shall be placed through brokers of its choice. Each investment manager appointed by the Partnership is authorized to execute security trades directly with respect to its respective Separate Account. Northern is hereby directed to receive and pay for securities purchased, in accordance with industry practice, and to deliver, in accordance with industry practice, securities sold, by the Partnership or by an investment manager. The Partnership has the right under applicable law to receive, at no additional cost, separate notifications of certain securities transactions; however, unless the Partnership directs otherwise in writing, the Partnership agrees not to receive such separate notifications of securities transactions and that all securities transactions will be reported on the Partnership’s periodic statements of account. Under no circumstance shall Northern pay any money to an investment manager except pursuant to written instructions by the Partnership. Northern shall issue its operating instructions to the Partnership and to an investment manager as it deems appropriate.

     4. Northern is authorized, but shall not be obligated, to credit the Account provisionally on payable date with interest, dividends, distributions, redemptions or other amounts due. Otherwise, such amounts will be credited to the Account on the date such amounts are actually received by Northern and reconciled to the Account. In cases where Northern has credited the Account with such amounts prior to actual collection and reconciliation, the Partnership agrees that Northern may reverse such credit as of payable date if and to the extent that it does not receive such amounts in the ordinary course of business. The Partnership acknowledges that Northern shall be entitled to recover from the Partnership on demand such provisional credit, plus its fee, applicable from time to time, in connection with such provisional credit.

     5. Northern is authorized, but shall not be obligated, to advance its own funds to complete transactions in cases where adequate funds may not otherwise be available to the Account. The Partnership acknowledges that Northern shall be entitled to repayment of any amounts advanced plus its fee, applicable from time to time, in connection with advancing such funds.

     6. The Partnership recognizes that any decision to effect a provisional credit or an advancement of Northern’s own funds to the Account pursuant to this Agreement will be an accommodation granted entirely at Northern’s option and in light of the particular circumstances, which circumstances may involve conditions in different countries, markets and classes of assets at different times. All amounts thus due to Northern under this agreement with respect to a provisional credit or advancement of Northern’s funds to the Account shall be paid by Northern from the Account unless otherwise paid by the Partnership on a timely basis and in that connection the Partnership acknowledges that Northern has a continuing lien on all Account assets to secure such payments and agrees that Northern may apply or set off against such amounts any amounts credited by or due from Northern to the Partnership. If funds in the Account are insufficient to make any such payment, the Partnership shall promptly deliver to Northern the amount of such

deficiency in immediately available funds when and as specified by Northern’s written or oral notification.

     7. Northern may execute and deliver as agent of the Partnership, and pursuant to the Partnership’s directions or the directions of an investment manager, any assignments, stock or bond powers or other documents or instruments and, in particular (a) may sell, assign, transfer, or make other disposition of any security or other property in the Account in accordance with industry practice; (b) may obtain any payment due; and (c) may make payment in accordance with industry practice for any securities purchased or otherwise acquired. Northern may execute any and all documents by signing as agent of the Partnership or as its attorney-in-fact pursuant to this authorization.

     8. Subject to contrary instructions from the Partnership or an investment manager, United States Dollars held by Northern shall be invested for short term purposes in the investment fund specified in a separate writing from the Partnership (which writing may be modified by the Partnership from time to time). The Partnership accepts that temporary cash investments may require additional documentation and such investments may include, without limitation, deposit obligations of Northern’s banking department or that of an affiliate, common and collective funds maintained by Northern or an affiliate, and money market mutual funds of which Northern or an affiliate may be a sponsor, investment advisor, manager or custodian, and from which Northern or an affiliate may receive separate compensation.

     9. Northern shall at all times exercise due care in dealing with the Accounts pursuant to the standard of care of a prudent, professional custodian for hire in the United States with the care, skill, prudence, and diligence under the circumstances then prevailing that a professional custodian acting in like capacity and familiar with such matters would use.

     10. If a corporation whose common stock declares a dividend in such stock, and payment of such dividend results in a fractional share, Northern shall sell such fraction.

     11. Northern’s duties shall be limited to those expressly set forth in this agreement. Northern shall have no obligation to make any investment review, to consider the propriety of holding or selling any property in the Account or to provide any advice. Northern shall incur no liability to the Partnership or the Account for any act taken or omitted by Northern or any of its agents pursuant to this agreement and shall be indemnified by the Partnership for any losses, expenses, penalties or taxes arising from following directions given to Northern pursuant to this agreement or for failing to act in the absence of directions. Northern shall have no responsibility for the solvency or financial condition of any agent engaged in connection with the provision of services to the Account, and shall incur no liability to the Partnership or the Account for any loss arising therefrom. This paragraph 11 shall survive the termination of this agreement.

     12. Northern shall furnish the Partnership with periodic statements of account showing all receipts and disbursements and the property in each Separate Account and the market value thereof. Northern shall provide the Partnership with daily access to

unaudited data pursuant to Northern’s Northern Trust Passport^® applications, subject to such additional terms and conditions as Northern may require. Account statements will be provided monthly. Northern shall incur no liability to the Partnership or the Account for any loss which may arise from the mispricing of Account assets by any broker, pricing service or other person upon whose valuation Northern relies in good faith. A statement of account shall be approved by the Partnership by written notice delivered to Northern or by failure to object to the statement of account within sixty (60) days of the date upon which the statement of account was delivered to the Partnership. To the extent permitted by law, the approval of a statement of account shall constitute a full and complete discharge to Northern as to all matters set forth in that statement of account. In no event shall Northern be precluded from having its statement of account settled by a judicial proceeding.

     13. This agreement may be terminated at any time upon thirty (30) days written notice from the Partnership to Northern or from Northern to the Partnership and upon the expiration of such forty-five (45) day period, Northern shall promptly deliver all cash, securities and other property then in the Account to the Partnership or in accordance with the Partnership’s order.

     14. The Partnership warrants that the performance by Northern of its duties in accordance with this agreement will not cause Northern to violate any applicable law, and that applicable law imposes no duties beyond those expressly assumed by Northern under this agreement.

     15. Northern shall receive such reasonable compensation for its services as agreed upon from time to time between it and the Partnership. In addition, Northern shall be reimbursed for any expenses (including accounting and legal fees) it reasonably incurs in connection with the Account. Those items of expense and compensation shall be paid from the Account unless otherwise agreed in writing. This paragraph 20 shall survive the termination of this agreement.

     16. Northern shall make distributions from the Account to such persons, in such amounts, at such times and in such manner as the Partnership shall from time to time direct in writing. Northern shall not be liable for any distribution made in good faith without actual notice or knowledge of the changed condition or status of the recipient. If any distribution made by Northern is returned unclaimed, it shall notify the Partnership and shall dispose of the distribution as the Partnership directs. Pursuant to making distributions, Northern may deposit cash in any depository including its own banking department, without any liability for the payment of interest thereon, notwithstanding Northern’s receipt of “float” from such uninvested cash.

     17. Northern shall have no duty to file any tax information, reports, returns or other filings of any kind except where it is directed by the Partnership and consents in writing to do so.

     18. The provisions of the law of New York shall govern the validity, interpretation and enforcement of this agreement. The invalidity of any part of this

agreement shall not affect the remaining parts hereof. This agreement may be modified at any time by a writing signed by the parties hereto.

     19. Any action required to be taken by the Partnership shall be by the written direction of one or more person or persons as shall be authorized by the Partnership and as identified in a certificate signed by the General Partner of the Partnership which certificate shall be filed with Northern. Northern may conclusively rely on a direction which it believes in good faith is from a person or persons identified as provided above until further written notice from the Partnership. Northern shall incur no liability to the Partnership or the Account for acting on any instruction, direction or other communication on which Northern is authorized to rely pursuant to this agreement, or for any delay in delivery or non-delivery or error in transmission.

In its sole discretion, Northern may, but shall not be required to, accept instructions, directions or other communications given to Northern by telephone. Any instructions, directions or other communications given to Northern by telephone shall promptly thereafter be confirmed in writing, but Northern will incur no liability for the Partnership’s failure, or the failure of an investment manager, to send such written confirmation or for the failure of any such written confirmation to conform to the telephonic instruction received by Northern.

     21. Northern shall incur no liability to the Partnership or the Account (i) for any indirect, incidental, consequential, special, exemplary or punitive damages, whether or not Northern knew of the likelihood of such damages, or (ii) for any delay in performance, or non-performance, of any obligation hereunder to the extent that the same is due to forces beyond Northern’s reasonable control, including but not limited to delays, errors or interruptions caused by the Partnership or third parties, any industrial, juridical, governmental, civil or military action, acts of terrorism, insurrection or revolution, nuclear fusion, fission or radiation, failure or fluctuation in electrical power, heat, light, air conditioning or telecommunications equipment, or acts of God.
