Section 2.5

Form of Shares; Book-Entry System; Transferability of Down MacroShares.

(a)

Form of Shares. The Down MacroShares shall be evidenced by one or more global certificates substantially in the form set forth in Exhibit A attached hereto, with appropriate insertions, modifications and omissions as hereinafter provided (each such certificate, a "Global Certificate"). No Down MacroShares shall be entitled to any benefits under this Trust Agreement or be valid or obligatory for any purpose unless a Global Certificate evidencing those Down MacroShares has been executed by the Trustee by the manual or facsimile signature of a duly authorized signatory of the Trustee and countersigned by the manual or facsimile signature of a duly authorized officer of the Depositor. The Trustee shall maintain books on which the registered ownership of each Global Certificate and transfers, if any, of such registered ownership shall be recorded. Global Certificates evidencing the Down MacroShares bearing the manual or facsimile signature of a duly authorized signatory of the Trustee and the manual or facsimile signature of a duly authorized officer of the Depositor, if applicable, who was, at the time such Global Certificates were executed, a proper signatory of the Trustee or the Depositor, as applicable, shall bind the Trustee, notwithstanding that such signatory has ceased to hold such office prior to the delivery of such Global Certificates. The Global Certificates may be endorsed with or have incorporated in the text thereof such legends or recitals or modifications not inconsistent with the provisions of this Trust Agreement as may be required by the Trustee or required to comply with any applicable law or regulations promulgated thereunder or with the rules and regulations of any securities exchange upon which the Down MacroShares may be listed or to conform with any usage with respect thereto, or to indicate any special limitations or restrictions to which the Down MacroShares are subject.

The Founders' Shares and the beneficial ownership thereof by the Depositor and the Administrative Agent shall be recorded on the books and records maintained by the Trustee on behalf of the Down Trust and no physical certificates shall be issued in respect of such Founders' Shares. Concurrently with the first Paired Issuance of Paired Shares, the Founders' Shares shall be cancelled and shall not thereafter be reissued.

(b)

Book-Entry Settlement. The Depositor and the Trustee shall apply to the Depository for acceptance of the Global Certificates in its book-entry settlement system. The Global Certificates shall be deposited with the Trustee, as the custodian for the Depository, shall be registered in the name of Cede & Co., as nominee for the Depository, and shall bear the following legend:

UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION (THE "DEPOSITORY"), TO THE AGENT AUTHORIZED BY THE DEPOSITOR FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY (AND ANY PAYMENT IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY), ANY TRANSFER, PLEDGE, OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.

So long as the Down MacroShares are eligible for book-entry settlement with the Depository, (i) no Beneficial Owner of Down MacroShares will be entitled to receive a physical certificate evidencing those shares, (ii) the interest of a Beneficial Owner in the Down MacroShares will be shown only on, and transfer of that interest will be effected only through, records maintained by the Depository or a DTC Participant or Indirect Participant through which the Beneficial Owner holds that interest and (iii) the rights of a Beneficial Owner of Down MacroShares will be exercised only to the extent allowed by, and in compliance with, the arrangements in effect between such Beneficial Owner and the Depository or the DTC Participant or Indirect Participant through which that Beneficial Owner holds an interest in the Down MacroShares.

As provided in the Depository Agreement, upon the settlement date for any creation, transfer or redemption of the Down MacroShares, the Depository will credit or debit, on its book-entry registration and transfer system, the amount of Down MacroShares so created, transferred or redeemed to the accounts of the appropriate DTC Participants. The accounts to be credited and charged shall be designated by the Trustee, as instructed by the Administrative Agent and the applicable Holder of Down MacroShares. The Beneficial Owners of the Down MacroShares will be shown on, and the transfer of beneficial ownership by Beneficial Owners will be effected only through, in the case of DTC Participants, records maintained by the Depository and, in the case of Indirect Participants and Beneficial Owners holding through a DTC Participant or an Indirect Participant, through those records or the records of the relevant DTC Participants. Beneficial Owners are expected to receive from or through the broker or bank that maintains the account through which the Beneficial Owner has purchased Down MacroShares a written confirmation relating to their purchase of Down MacroShares.

Upon the settlement date for any creation, transfer, redemption or exchange of Down MacroShares, the Trustee shall make a notation on Schedule A attached to the Global Certificate indicating the resulting Net Par Amount Increase or Net Par Amount Decrease in the Aggregate Par Amount of Outstanding Down MacroShares represented by such Global Certificate. Upon the settlement date for a transfer of a Global Certificate to a new Registered Owner as described in clause (e)(ii) of this Section 2.5, the Trustee shall cancel such Global Certificate and issue a new Global Certificate in the name of such transferee Registered Owner.

The Depository may discontinue providing its services with respect to the Down MacroShares by giving notice to the Trustee, the Administrative Agent and the Depositor pursuant to and in conformity with the provisions of the Depository Agreement and discharging its responsibilities with respect thereto under applicable law. In such event, the Trustee, the Administrative Agent and the Depositor shall seek to find a replacement for the Depository to perform the functions thereof on terms acceptable to the Administrative Agent and the Depositor. If no such replacement can be found or is willing to assume the duties of the Depository, then a Termination Trigger will occur pursuant to Section 11.1 of this Trust Agreement.

(c)

Notices to Beneficial Owners. As described above, the Trustee will recognize the Depository or its nominee as the owner of all Down MacroShares for all purposes except as expressly set forth in this Trust Agreement. Conveyance of all notices, statements and other communications required to be delivered to Beneficial Owners will be effected as follows: The Administrative Agent shall inquire of each such DTC Participant as to the number of Beneficial Owners holding Down MacroShares, directly or indirectly, through such DTC Participant. The Administrative Agent shall provide each such DTC Participant with sufficient copies of such notice, statement or other communication, in such form, number and at such place as such DTC Participant may reasonably request, in order that such notice, statement or communication may be transmitted by such DTC Participant, directly or indirectly, to such Beneficial Owners. In addition, the Down Trust shall reimburse each such DTC Participant for the expenses attendant to such transmittal, subject to applicable statutory and regulatory requirements.

(d)

Distributions on Book-Entry Certificates. All distributions on the Down MacroShares shall be made to the Depository or its nominee, Cede & Co., as the registered owner of all Down MacroShares. The Trustee and the Depositor expect that the Depository or its nominee, upon receipt of any distributions made in respect of the Down MacroShares, shall credit immediately the DTC Participants' accounts with payments in amounts proportionate to their respective beneficial interests in the Down MacroShares as shown on the records of the Depository or its nominee. The Trustee and the Depositor also expect that payments by DTC Participants to Indirect Participants and Beneficial Owners held through such DTC Participants and Indirect Participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers in bearer form or registered in a "street name," and shall be the responsibility of such DTC Participants and Indirect Participants. None of the Trustee, the Depositor or the Administrative Agent shall have any responsibility or liability for any aspects of the records relating to or notices to Beneficial Owners, or payments made on account of beneficial ownership interests in the Down MacroShares, or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests or for any other aspect of the relationship between the Depository and the DTC Participants or the relationship between such DTC Participants and the Indirect Participants and Beneficial Owners owning through such DTC Participants or Indirect Participants or between or among the Depository, any Beneficial Owner and any Person by or through which such Beneficial Owner is considered to own Down MacroShares.

(e)

Registration of Transfer; Restrictions on Transfer.

(i)

The Trustee shall cause to be kept at its Corporate Trust Office a register (the "Share Register") in which, subject to such reasonable regulations as it may prescribe, a transfer agent and registrar (the "Transfer Agent and Registrar") shall provide for the registration of the Down MacroShares in the Share Register and of transfers and exchanges of such shares as herein provided. The Transfer Agent and Registrar shall initially be the Trustee. The Depositor may revoke such appointment and remove any Transfer Agent and Registrar if the Depositor determines in its sole discretion that such Transfer Agent and Registrar failed to perform the responsibilities of the Transfer Agent and Registrar set forth in this Trust Agreement in any material respect. Any Transfer Agent and Registrar shall be permitted to resign as Transfer Agent and Registrar upon thirty (30) days' notice to the Depositor and the Trustee; provided, however, that such resignation shall not be effective and such Transfer Agent and Registrar shall continue to perform its duties as Transfer Agent and Registrar until the Trustee has appointed a successor Transfer Agent and Registrar reasonably acceptable to the Depositor.

(ii)

Transfers of the Global Certificates shall be limited to transfers of such Global Certificates in whole, but not in part, to nominees of the Depository or to a successor of the Depository or such successor's nominee. When a Global Certificate is presented for registration of transfer, the Depositor shall execute, the Trustee shall authenticate and the Transfer Agent and Registrar shall register one or more new Global Certificates in the name of the designated transferee or transferees. Each Global Certificate presented for registration of transfer shall be accompanied by a written instrument of transfer in a form satisfactory to the Trustee or the Transfer Agent and Registrar duly executed by the Registered Owner or the attorney-in-fact thereof duly authorized in writing. No service charge shall be made for any registration of transfer or exchange of Down MacroShares, but the Transfer Agent and Registrar may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any such transfer or exchange.

(f)

Mutilated, Destroyed, Lost or Stolen Shares. If (a) any mutilated Global Certificate is surrendered to the Transfer Agent and Registrar, or the Transfer Agent and Registrar receives evidence to its satisfaction of the destruction, loss or theft of any Global Certificate and (b) there is delivered to the Transfer Agent and Registrar and the Trustee such security or indemnity as may be required by them to save each of them harmless, then in the absence of notice to the Trustee that such Global Certificate has been acquired by a bona fide purchaser, the Depositor shall execute, the Trustee shall authenticate and the Transfer Agent and Registrar shall deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Global Certificate, a new Global Certificate of like tenor and aggregate beneficial interest. In connection with the issuance of any new Global Certificate under this Section 2.5(f), the Trustee or the Transfer Agent and Registrar may require the payment by the Registered Owner of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee and the Transfer Agent and Registrar) connected therewith. Any duplicate Global Certificate issued pursuant to this Section 2.5(f) shall constitute complete and indefeasible evidence of ownership in the Down Trust, as if originally issued, whether or not the lost, stolen or destroyed Global Certificate shall be found at any time.

CALCULATIONS

Section 4.1

Calculations on Price Determination Days.

(a)

With respect to each Price Determination Day, the Trustee shall calculate and provide to the Administrative Agent and the Calculation Agent, within the time period agreed upon by the Trustee, the Administrative Agent and the Calculation Agent, the following data:

(i)

the sum of the Down Earned Income Accruals for each day that has elapsed during the current Calculation Period;

(ii)

the Down Investment Amount for that day;

(iii)

the estimated Down Available Income Accrual for that day; and

(iv)

the estimated Down Available Income Accrual for any intervening non-Business Days between such Price Determination Day and the next succeeding Price Determination Day.

(b)

On each Price Determination Day, the Trustee shall calculate and provide to the Administrative Agent for posting on the MacroShares Website, not later than one hour prior to the commencement of trading on the AMEX, the Per Share Underlying Value of one Down MacroShare on the last preceding Price Determination Day, subject to the availability of, and based upon (i) the Applicable Reference Price of Crude Oil for such preceding Price Determination Day and (ii) the calculations of the Up Trustee pursuant to Section 8.1 of the Up Trust Agreement.

For purposes of calculating the foregoing amounts on any Price Determination Day, any Paired Optional Redemptions or Paired Issuances scheduled to settle on such Price Determination Day shall be taken into account.

(c)

The Trustee's calculations, pursuant to clauses (a) and (b) of this Section 4.1 shall be conclusive and binding upon the Holders of the Down MacroShares, the Holders of the Up MacroShares and all other Persons, absent manifest error.

Section 4.2

Calculation of Intraday Indicative Values.

Intraday indicative values for the Down Underlying Value of the Down Trust and the Per Share Underlying Value for the Down MacroShares based on the intraday trading prices of the Applicable Reference Price of Crude Oil will be calculated by the Calculation Agent under the Calculation Agency Agreement based upon the Applicable Reference Price of Crude Oil and the data provided to the Calculation Agent by the Trustee pursuant to Section 4.1 hereof and by the Up Trustee pursuant to Section 4.1 of the Up Trust Agreement.

Section 4.3

Calculation on Distribution Dates, on Redemption Dates, on an Early Termination Date and on the Final Scheduled Termination Date.

(a)

On the last Price Determination Day preceding each Distribution Date, within the time period agreed upon by the Trustee and the Administrative Agent, the Trustee shall calculate the Down Income Distribution Payment, if any, that the Down Trust is required to make to the Up Trust on the related Distribution Payment Date or the Up Income Distribution Payment, if any, that the Up Trust is required to make to the Down Trust on the related Distribution Payment Date pursuant to the Income Distribution Agreement, and (ii) the Quarterly Distribution payable to Holders of the Up MacroShares on the related Distribution Payment Date. The Trustee shall perform the calculations described in this Section 4.3(a) by assuming that the Applicable Reference Price of Crude Oil for any Price Determination Day on which such price was not available or on which the Down Trust was no longer permitted to use such price was the same as the Applicable Reference Price of Crude Oil on the last preceding Price Determination Day on which such price was available or permitted to be used by the Down Trust.

(b)

The Trustee shall calculate and provide to the Administrative Agent, within the time period agreed upon by the Trustee and the Administrative Agent as of the last Price Determination Day preceding the Final Scheduled Termination Date or any Early Termination Date and on the Redemption Order Date preceding each Redemption Date, (i) (x) the Up Settlement Payment, if any, required to be made by the Up Trust to the Down Trust under the Settlement Contracts that are being settled in connection with such Final Scheduled Termination Date, Early Termination Date or Redemption Date or (y) the Up Settlement Payment, if any, required to be made by the Up Trust to the Down Trust under the Settlement Contracts that are being settled in connection with such Final Scheduled Termination Date, Early Termination Date or Redemption Date, and (ii) the Final Distribution payable to Holders of the Up MacroShares on such Redemption Date, Early Termination Date or Final Scheduled Termination Date. The Trustee shall perform the calculations described in this Section 4.3(b) (including, without limitation, with respect to an Early Termination Date) by assuming that the Applicable Reference Price of Crude Oil for any Price Determination Day on which such price was not available or on which the Down Trust was no longer permitted to use such price was the same as the Applicable Reference Price of Crude Oil on the last preceding Price Determination Day on which such price was available or permitted to be used by the Down Trust.

(c)

The Trustee shall confirm the Administrative Agent's determination of the Redemption Cash Component, if any, that must be delivered by the redeeming Authorized Participants in connection with a Paired Optional Redemption not later than the Redemption Order Date for such Paired Optional Redemption.

ARTICLE 6

REDEMPTIONS AND ISSUANCES OF SHARES;
THE ADMINISTRATION AND REINVESTMENT OF THE ELIGIBLE TREASURIES

Section 6.1

Paired Optional Redemptions.

(a)

On any Price Determination Day occurring after the Closing Date but prior to the Final Scheduled Termination Date or an Early Termination Date, any Authorized Participant may direct the redemption of Paired Shares by delivering a Redemption Order to the Administrative Agent and satisfying the conditions set forth in this Section 6.1 (such redemption, a "Paired Optional Redemption"). The Authorized Participant directing the Paired Optional Redemption must be the Beneficial Owner of the Paired Shares which are being tendered for redemption, as shown on the records of the Depository. Only Authorized Participants may direct Paired Optional Redemptions. Down MacroShares will be redeemed at their Per Share Underlying Value, as calculated on the Redemption Order Date on which the related Redemption Order was delivered; provided, that, in the case of any Redemption Order placed on a Distribution Date or on the Business Day succeeding a Distribution Date, such Final Distribution will also include Down and Up Earned Income Accruals for each intervening day between the Redemption Order Date and the Redemption Date calculated on the basis of the Applicable Reference Price of Crude Oil on the Redemption Order Date.

(b)

Subject to the procedures and requirements specified in the Participants Agreement, the redeeming Authorized Participants may effect a Paired Optional Redemption by delivering a Redemption Order to the Administrative Agent on any day that is a Price Determination Day (such date, a "Redemption Order Date") not later than the earlier of (i) half an hour prior to the end of trading in the Light Sweet Crude Oil Futures Contracts or prior to the time as of which any Substitute Reference Oil Price is made available by the applicable Substitute Oil Price Provider and (ii) the unanticipated close of trading of the Light Sweet Crude Oil Futures Contracts or of the Substitute Reference Oil Price. Any Redemption Order received by the Administrative Agent after the time specified in the foregoing sentence may be rejected at the option of the Administrative Agent. If so rejected, such Redemption Order may be resubmitted by the applicable Authorized Participant, if it so desires, on the next Price Determination Day at that day's Per Share Underlying Value. Following the Redemption Order Date, the redeeming Authorized Participant must transfer to the Trustee, not later than the date and time specified in the Participants Agreement, (i) the requisite number of Paired Shares constituting at least one MacroShares Unit or integral multiples thereof, (ii) the applicable Redemption Cash Component, if any, and (iii) the transaction fee described in clause (e) of this Section 6.1, and provide written or electronic evidence of the required transfer of shares and the required deposit of immediately available funds to the Administrative Agent in accordance with the Participants Agreement.

(c)

The Administrative Agent shall have the right, but not any obligation, to reject any Redemption Order for the reasons specified in the Participants Agreement. None of the Trustee, the Depositor or the Administrative Agent shall be liable to any Person for the Administrative Agent's rejection of a Redemption Order pursuant to the provisions of the Participants Agreement.

(d)

If the Redemption Order Date on which a Paired Optional Redemption was directed is not a Distribution Date and there are insufficient funds on deposit in the Cash Netting Subaccount delivered in connection with Paired Issuances directed on the same date as such Paired Optional Redemption and in the Distribution Account from maturing Eligible Treasury Repurchase Agreements, as determined in accordance with Section 6.4, the Administrative Agent shall deliver instructions to the Trustee with respect to the Eligible Treasuries then on deposit in the Down Trust, in which the Administrative Agent, employing "last in, first out" methodology and complying in all respects with the requirements and conditions set forth in Exhibit H hereto, shall:

(i)

identify and segregate the Eligible Treasuries on deposit in the Down Trust that are the most recently-acquired Eligible Treasuries with a Value equal to the product of the Down Redemption Percentage and the Down Asset Amount (or the portion thereof that is not available to be delivered in cash);

(ii)

(A) select from among the segregated Eligible Treasuries with a Value equal to the Down Settlement Payment, if any such payment is required to be made by the Down Trust, (B) allocate the remaining Eligible Treasuries to be delivered as a Final Distribution to the Authorized Participants directing the Paired Optional Redemption and (C) in the event that the Value of such remaining Eligible Treasuries to be delivered as a Final Distribution exceeds the amount due to the Authorized Participants directing the Paired Optional Redemption, calculate the amount to be paid by the Authorized Participants to the Down Trust to compensate the trust for the excess Value of the Eligible Treasuries being delivered to the Authorized Participants as a Final Distribution (such amount, the "Redemption Cash Component"); and

(iii)

instruct the Trustee as to which Eligible Treasuries the Trustee is to use to effect the Paired Optional Redemption and, of those, (A) the Eligible Treasuries to be used to make the Down Settlement Payment, if any, (B) the Eligible Treasuries to be used to make the Final Distribution to the redeeming Authorized Participants and (C) the Redemption Cash Component to be collected from the Authorized Participants, if any.

The Eligible Treasuries selected by the Administrative Agent to be delivered as the Final Distribution in a Paired Optional Redemption shall be distributed ratably, by type, to each redeeming Authorized Participant. A "type" of Eligible Treasury will include all Eligible Treasuries on deposit in the Down Trust with the same acquisition date, the same purchase price, the same maturity and the same implied discount or stated interest. The Trustee shall cause the Down Trust to deliver Eligible Treasuries pursuant to this Section 6.1(d) only in accordance with the directions of the Administrative Agent. If the Administrative Agent violates any of the requirements or conditions set forth in Exhibit H in the course of directing the Trustee in the selection and distribution of Eligible Treasuries "in kind" pursuant to this Section 6.1(d), the Administrative Agent shall undertake to remedy such violation in the manner specified in such Exhibit H.

(e)

A non-refundable transaction fee will be payable to the Trustee for its own account in connection with each Redemption Order in the amount specified in Section 7 of the Participants Agreement. In the event that a Redemption Order fails and the Trustee or the Administrative Agent has incurred expenses on behalf of the Down Trust in connection with taking steps to effect a Paired Optional Redemption pursuant thereto, and any reimbursement of such expenses cannot be obtained from the Authorized Participant who delivered the Redemption Order, then such expenses shall be reimbursed to the Trustee and the Administrative Agent on the next Distribution Payment Date out of funds available in the Fee Payment Account.

(f)

On any Distribution Date that is an Early Termination Date or on the Final Scheduled Termination Date, the Trustee shall redeem all of the Down MacroShares that are Outstanding on such Distribution Date at their Per Share Underlying Value, as calculated on the immediately preceding Price Determination Day, using the funds that are on deposit in the Distribution Account after all of the Settlement Contracts have been settled, as specified in priority third of Section 5.2(a).

Section 6.2

Paired Issuances.

(a)

On any Price Determination Day that occurs after the Closing Date but prior to the Final Scheduled Termination Date or an Early Termination Date, the Down Trust shall issue additional Down MacroShares contemporaneously with the issuance of additional Up MacroShares in the form of MacroShares Units (such an issuance, a "Paired Issuance") following the receipt of, and in accordance with, a Creation Order delivered by an Authorized Participant and forwarded to the Trustee by the Administrative Agent. Only Authorized Participants may direct Paired Issuances. Down MacroShares will be issued at the Per Share Underlying Value of the existing Down MacroShares on the Issuance Order Date on which the related Creation Order was delivered; provided that in the case of any Creation Order placed on a Distribution Date or on the Business Day succeeding a Distribution Date, the Authorized Participant submitting the Creation Order will be required to deliver, in addition to cash in the amount of the aggregate per share Underlying Value of the Down MacroShares being created, an amount equal to the Down and Up Earned Income Accruals for each intervening day between the Issuance Order Date and the Issuance Date, calculated on the basis of the Applicable Reference Price of Crude Oil on the Issuance Order Date.

(b)

Subject to the procedures and requirements specified in the Participants Agreement, a Paired Issuance may be made only upon the direction of one or more Authorized Participants delivered in the form of a Creation Order to the Administrative Agent on any day that is a Price Determination Day (such date, the "Issuance Order Date"), prior to the earlier of (i) half an hour before the end of trading in the Light Sweet Crude Oil Futures Contracts on NYMEX or half an hour before the end of trading in the futures contracts from which any Substitute Reference Oil Price is derived or at such time as may be specified for any other applicable Substitute Reference Oil Price and (ii) the unanticipated close of trading of the Light Sweet Crude Oil Futures Contracts or of the Substitute Reference Oil Price. Any Creation Order received by the Administrative Agent after the time specified in the foregoing sentence may be rejected at the option of the Administrative Agent on such Price Determination Day. If so rejected, such Creation Order may be resubmitted by the applicable Authorized Participant, if it so desires, on the next Price Determination Day at the Per Share Underlying Value as of the Creation Valuation Date that is related to the Issuance Date that follows such Business Day. Subject to the requirements and limitations set forth herein and in the Participants Agreement, the number of Up MacroShares that the Up Trust may issue as part of a Paired Issuance is unlimited.

(c)

The Administrative Agent shall have the right, but not any obligation, to reject any Creation Order for the reasons specified in the Participants Agreement. None of the Trustee, the Depositor or the Administrative Agent shall be liable to any Person for the Administrative Agent's rejection of a Creation Order pursuant to the provisions of the Participants Agreement.

(d)

A non-refundable transaction fee will be payable to the Trustee for its own account in connection with each Creation Order in the amount specified in Section 7 of the Participants Agreement. In the event that a Creation Order fails and the Trustee or the Administrative Agent has incurred expenses on behalf of the Down Trust in connection with taking steps to effect a Paired Issuance pursuant thereto, and any reimbursement of such expenses cannot be obtained from the Authorized Participant who delivered the Creation Order, then such expenses shall be reimbursed to the Trustee and the Administrative Agent on the next Distribution Payment Date out of funds available in the Fee Payment Account or, if such funds are insufficient.

Section 6.3

Settlement of the Settlement Contracts; Adjustments to the Notional Amount of the Income Distribution Agreement.

(a)

In connection with a Paired Optional Redemption directed on a Redemption Date that is not also an Issuance Date, the Trustee, acting together with the Up Trustee, each on behalf of its respective Paired Trust and at the direction of the Administrative Agent, will settle one Settlement Contract for each MacroShares Unit that is redeemed and amend the Income Distribution Agreement to reduce the notional amount thereof to reflect the decrease in the Aggregate Par Amount of Down and Up MacroShares that are Outstanding.

(b)

In connection with a Paired Issuance directed on an Issuance Date that is not also a Redemption Date, the Trustee, acting together with the Up Trustee, each on behalf of its respective Paired Trust and at the direction of the Administrative Agent, will enter into one Settlement Contract for each MacroShares Unit that is created and amend the Income Distribution Agreement to increase the notional amount thereof to reflect the increase in the Aggregate Par Amount of Down and Up MacroShares that are Outstanding.

(c)

In connection with any Paired Optional Redemptions and Paired Issuances for which Redemption Orders and Creation Orders, as applicable, are received on the same Business Day, the Trustee, acting together with the Up Trustee, each on behalf of its respective Paired Trust and at the direction of the Administrative Agent, shall (i) amend the Income Distribution Agreement to increase or decrease the notional amount thereof based on the Net Par Amount Increase or Net Par Amount Decrease that was directed on such Business Day, and (ii) enter into additional Settlement Contracts, based on the Net Par Amount Increase that was directed on such Business Day or settle existing Settlement Contracts, based on the Net Par Amount Decrease that was directed on such Business Day.

(d)

Each amendment to the Income Distribution Agreement shall be in the form of Exhibit B hereto, and each Settlement Contract shall be in the form of Exhibit C hereto and shall constitute an additional confirmation to the Master Agreement.

(e)

In connection with each Paired Optional Redemption and each Paired Issuance, Schedule A of one or more of the Global Certificates will be adjusted (and, if necessary, additional Global Certificates will be issued) to reflect the Net Par Amount Decrease or the Net Par Amount Increase, as applicable, in the Aggregate Par Amount of the Down MacroShares that are Outstanding after giving effect to such Paired Optional Redemption and/or Paired Issuance. On the Final Scheduled Termination Date or an Early Termination Date, after a Final Distribution has been made on the Down MacroShares, all Outstanding Up MacroShares shall be cancelled by the Trustee, on behalf of the Down Trust, in accordance with the procedures of the Depository. On any Redemption Date on which a Net Par Amount Decrease occurred, Down MacroShares in an amount equal to such Net Par Amount Decrease shall be cancelled by the Trustee, on behalf of the Down Trust, in accordance with the procedures of the Depository.

Section 6.4

Section 6.5

Settlement of Issuances.

(a)

On the next Business Day after the applicable Issuance Order Date or, in the event that the Issuance Order Date is a Distribution Date or the Business Day following the Distribution Date, on the third Business Day after the Issuance Order Date (such date, the "Issuance Date"), not later than 10:00 a.m. New York City Time, the Authorized Participant directing the Paired Issuance must deliver immediately available funds to the Trustee in an amount equal to (i) the Per Share Underlying Value of Up MacroShares on the related Issuance Order Date multiplied by the number of Up MacroShares being created by that Authorized Participant, plus (ii) the Per Share Underlying Value of Down MacroShares on the related Issuance Order Date multiplied by the number of Down MacroShares being created by that Authorized Participant, plus (iii) the non-refundable transaction fee described in Section 6.2(d), plus (iv) in the case of any Creation Order placed (A) on a Distribution Date, (B) on the Business Day succeeding a Distribution Date or (C) on an Issuance Order Date that is followed by one or more intervening non-Business Days before the Creation Order is settled on the related Issuance Date, the Down and Up Earned Income Accruals for each intervening day between the Issuance Order Date and the Issuance Date, calculated on the basis of the Applicable Reference Price of Crude Oil on the Issuance Order Date. Following the delivery of requisite funds and satisfaction of the procedures and conditions for a Paired Issuance that are specified in the Participants Agreement and no later than the day and time specified in the Participants Agreement, the Trustee, acting together with the Up Trustee, each on behalf of its respective Paired Trust and as directed by the Administrative Agent, shall credit the Depository account of the Authorized Participant who directed such Paired Issuance, as applicable, with such Paired Shares in the Aggregate Par Amount that was specified in the Creation Order. The Trustee shall obtain the Up MacroShares so credited from the Shares Netting Subaccount or, in the event of a Net Par Amount Increase, by causing each of the Paired Trusts to issue Paired Shares in the Aggregate Par Amount of such Net Par Amount Increase.

(b)

Upon receipt of the aggregate funds delivered by one or more Authorized Participants in connection with a Paired Issuance, 50% of such funds shall be deposited into the Down Trust and 50% of such funds shall be deposited into the Up Trust, without regard to the Per Share Underlying Values at which the Down and Up MacroShares were issued, in order to preserve the one-to-one proportion of cash and Eligible Treasuries in the Paired Trusts.

Section 6.6

Suspension or Delay of Settlement.

(a)

The Administrative Agent shall suspend the right of redemption or creation, or postpone the date of settlement for any Paired Optional Redemption or any Paired Issuance of Paired Shares,

(i)

for any period during which the AMEX or NYMEX is closed, or trading is suspended or restricted;

(ii)

for any period during which an emergency exists as a result of which delivery or acquisition of Eligible Treasuries by the Paired Trusts is not reasonably practicable;

(iii)

if any such redemption would cause the Down or Up Investment Amount to equal less than 10 million dollars; and

(iv)

for such other period as the Administrative Agent determines to be necessary for the protection of the Beneficial Owners of any of the Paired Shares.

None of the Depositor, the Trustee or the Administrative Agent will be liable to any Person for any loss or damages that may result from any such suspension or postponement.

Section 6.7

The Participants Agreement.

(b)

The Trustee and the Administrative Agent shall only process Redemption Orders and Creation Orders from Authorized Participants who have executed a Participants Agreement that is in full force and effect at the time when the Redemption Order or Creation Order is placed. The Administrative Agent will maintain and make available at its Business Office during normal business hours a current list of the Authorized Participants eligible to participate in a Paired Issuance.

(c)

In the event that the provisions of this Trust Agreement and the Participants Agreement conflict in any way, the provisions of the Participants Agreement will prevail insofar as such provisions relate (i) to the requirements and procedures for directing and effecting Paired Optional Redemptions and Paired Issuances or (ii) to the circumstances which the Administrative Agent may reject any Redemption Order or any Creation Order or suspend or postpone the settlement of any Paired Optional Redemption or Paired Issuance.

Section 6.8

Administration of Eligible Treasuries.

(a)

The Trustee, acting on behalf of the Down Trust and at the direction of the Administrative Agent, shall apply funds in the amount specified in Section 5.2(a)(iv) on each Distribution Date, all funds received in connection with each Paired Issuance, to the extent such funds are not withdrawn from the Netting Account in connection with a Paired Optional Redemption, and any maturity proceeds of Eligible Treasuries that are received prior to the end of any Calculation Period, to acquire Eligible Treasuries. The Administrative Agent shall direct the Trustee to acquire Eligible Treasuries in accordance with the following "Acquisition Guidelines":

(i)

dealers from whom the Paired Trusts will purchase Eligible Treasury Securities shall be selected based on best execution;

(ii)

counterparties with whom the Paired Trusts will enter into Eligible Treasury Repurchase Agreements shall be selected based on best execution;

(iii)

no Eligible Treasury Repurchase Agreement may be entered into with, and no Eligible Treasury Security may be purchased from, any person who is an Affiliated Person with respect to any of the Depositor, either of the Paired Trusts, the Trustee, the Administrative Agent, or the Marketing Agent;

Eligible Treasury Repurchase Agreements may be entered into with, and Eligible Treasury Securities may be to be purchased from, an Authorized Participant or an Affiliated Person of both the Down Trust and an Authorized Participant only in accordance with the requirements and conditions set forth in Exhibit H;

(v)

Eligible Treasuries shall be allocated as between the Down Trust and the Up Trust in such a manner that each of the Paired Trusts shall hold an identical portfolio of Eligible Treasuries or as close to an identical portfolio as is commercially feasible; and

(vi)

the allocation of funds among Eligible Treasury Securities and Eligible Treasury Repurchase Agreements during any Calculation Period (the "Asset Allocation Percentage") shall be a minimum of 65% in Eligible Treasury Securities and a maximum of 35% in Eligible Treasury Repurchase Agreements for the first 12 months following the first Issuance Date and, thereafter, the Administrative Agent shall use commercially reasonable efforts to adjust such Asset Allocation Percentage on behalf of the Down Trust on every other Distribution Date such that the amount invested in Eligible Treasury Repurchase Agreements is equal to up to 10% plus the highest percentage of Down MacroShares that were redeemed on any one Redemption Date (relative to all Outstanding Down MacroShares on such Redemption Date) during the preceding twelve-month period.

The Trustee shall cause the Down Trust to acquire Eligible Treasuries pursuant to this Section 6.8 only in accordance with the directions of the Administrative Agent. If the Administrative Agent violates any of the requirements or conditions set forth in Exhibit H in the course of directing the Trustee in the acquisition of Eligible Treasuries, the Administrative Agent shall undertake to remedy such violation in the manner specified in such Exhibit H.

(b)

On each Distribution Date and on each Issuance Order Date, the Administrative Agent shall, subject to, and in accordance with, the Acquisition Guidelines and the Asset Allocation Percentage, solicit offers for Eligible Treasuries and shall place a purchase order for the selected Eligible Treasuries with one or more securities dealers and shall direct the Trustee to settle such acquisition. The Administrative Agent shall direct the Trustee and the Up Trustee in allocating all Eligible Treasury Securities acquired as described above equally between the Down Trust and the Up Trust. Eligible Treasury Securities allocated to the Down Trust on each Distribution Date, Issuance Date or any other date shall be credited by the Trustee to the Securities Account.

(c)

On each Distribution Date and on each Issuance Order Date, the Administrative Agent shall, subject to, and in accordance with, the Acquisition Guidelines and the Asset Allocation Percentage solicit offers for Eligible Treasury Repurchase Agreements and shall direct the Trustee to enter into such Eligible Treasury Repurchase Agreements and shall place a purchase order for such Eligible Treasury Repurchase Agreements with one or more counterparties. The Trustee shall allocate all Eligible Treasury Repurchase Agreements as described above equally between the Down Trust and the Up Trust, as directed by the Administrative Agent. Eligible Treasury Repurchase Agreements entered into on each Distribution Date, Issuance Date or any other date shall be credited by the Trustee to the Securities Account.

(d)

On any Business Day during any Calculation Period (other than the last Business Day prior to a Distribution Date), if cash is available in the Distribution Account for reinvestment in Eligible Treasuries, the Administrative Agent shall provide instructions to the Trustee to apply such cash to purchase Eligible Treasuries in accordance with the Acquisition Guidelines and the Asset Allocation Percentage.

(e)

Without limiting the generality of Section 13.1 and Section 13.2, the Trustee shall not under any circumstances be held liable under this Trust Agreement for any action it takes in accordance with directions provided to it by the Administrative Agent under this Section 6.8 or for any omission on the part of the Trustee to take any action in the absence of receiving such instructions from the Administrative Agent.

ARTICLE 7

CAPITAL ACCOUNTS OF HOLDERS
AND OPERATION THEREOF; TAX ALLOCATIONS

Section 7.1

Capital Contributions.

(a)

Each Holder has made an initial Capital Contribution (as defined below) to the Down Trust in cash equal to the amount paid for its Down MacroShares. Except as provided for herein, a Holder shall not be required to make any further Capital Contributions to the Down Trust.

(b)

Except as expressly set forth herein, no Holder shall be entitled to any return of capital, interest or compensation by reason of its Capital Contributions.

Section 7.2

Capital Accounts; Allocations. There shall be established in respect of each Holder a separate capital account in the books and records of the Down Trust in respect of the Holder's Capital Contributions to the Down Trust (each, a "Capital Account"), to which the following provisions shall apply:

(a)

The Capital Account of each Holder initially shall be equal to the cash contributed in exchange for its Down MacroShares (each, a "Capital Contribution") and, at the end of each day shall be:

(i)

increased by (A) an amount equal to any amounts paid with respect to Down MacroShares issued as part of a Paired Issuance by such Holder during such day; and (B) such Holder's interest in the Net Profit (and items thereof) of the Down Trust during such day as allocated under Section 7.2(b); and

(ii)

decreased by (A) any distributions made in cash by the Down Trust to such Holder on such day; (B) the fair market value of any property other than cash distributed by the Down Trust to such Holder on such day; and (C) such Holder's interest in the Net Loss (and items thereof) of the Down Trust for such day as allocated under Section 7.2(b).

(b)

Except pursuant to the Regulatory Allocations set forth in Section 7.3, or as otherwise provided in this Trust Agreement, Net Profit and Net Loss (and items of each) of the Down Trust shall be provisionally allocated as of the end of each day among the Holders in a manner such that the Capital Account of each Holder immediately after giving effect to such allocation, is, as nearly as possible, equal (proportionately) to the amount equal to the distributions that would be made to such Holder during such fiscal year pursuant to Article 5 if (i) the Down Trust were dissolved and terminated; (ii) its affairs were wound up and each Trust Asset was sold for cash equal to its book value; (iii) all Down Trust liabilities were satisfied (limited with respect to each nonrecourse liability to the book value of the assets securing such liability); and (iv) the net assets of the Down Trust were distributed in accordance with Article 5 to the Holders immediately after giving effect to such allocation. The Depositor may, in its discretion, make such other assumptions (whether or not consistent with the above assumptions) as it deems necessary or appropriate in order to effectuate the intended economic arrangement of the Holders. Except as otherwise provided elsewhere in this Trust Agreement, if upon the dissolution and termination of the Down Trust pursuant to Section 14.1 and after all other allocations provided for in this Section 7.2 have been tentatively made as if this Section 7.2(b) were not in this Trust Agreement, a distribution to the Holders under Section 14.1 would be different from a distribution to the Holders under Article 5 then Net Profit (and items thereof) and Net Loss (and items thereof) for the fiscal year in which the Down Trust dissolves and terminates pursuant to Section 14.1 shall be allocated among the Holders in a manner such that the Capital Account of each Holder, immediately after giving effect to such allocation, is, as nearly as possible, equal (proportionately) to the amount of the distribution that would be made to such Holder during such last fiscal year pursuant to Article 5. The Depositor may, in its discretion, apply the principles of this Section 7.2(b) to any fiscal year preceding the fiscal year in which the Down Trust dissolves and terminates (including through application of Section 761(e) of the Code) if delaying application of the principles of this Section 7.2(b) would likely result in distributions under Section 14.1 that are materially different from distributions under Article 5 in the fiscal year in which the Down Trust dissolves and terminates.

(c)

Before any distribution of property (other than cash) from the Down Trust to a Holder (including without limitation, any non-cash asset which shall be deemed distributed immediately prior to the dissolution and winding up of the Down Trust), the Capital Accounts of all Holders of the Down Trust shall be adjusted and, upon the occurrence of one or more of the other events described in Section 1.704-1(b)(2)(iv)(f) of the Regulations, may be adjusted to reflect the manner in which any unrealized income, gain, loss or deduction inherent in such property (that has not been previously reflected in the Holders' Capital Accounts) would be allocated among the Holders if there were a taxable disposition of such property by the Down Trust on the date of distribution, in accordance with Sections 1.704-1(b)(2)(iv)(f) and (g) of the Regulations.

(d)

In determining the amount of any liability for purposes of this Section 7.2, there shall be taken into account Section 752 of the Code and any other applicable provisions of the Code and any Regulations promulgated thereunder.

(e)

Notwithstanding any other provision of this Trust Agreement to the contrary, the provisions of this Section 7.2 regarding the maintenance of Capital Accounts shall be construed so as to comply with the provisions of the Code and any Regulations thereunder. The Depositor in its sole and absolute discretion and whose determination shall be binding on the Holders is hereby authorized to interpret and to modify the foregoing provisions to the extent necessary to comply with the Code and Regulations.

Section 7.3

Regulatory and Related Allocations. Notwithstanding any other provision in this Article 7 to the contrary, the following special allocations shall be made to the Capital Accounts of the Holder in the following order:

(a)

Minimum Gain Chargeback. If there is a net decrease in Partnership Minimum Gain during any taxable year, each Holder shall be specially allocated items of Down Trust income and gain for such taxable year (and, if necessary, subsequent taxable years) in an amount equal to the greater of (A) the portion of such Holder's share of the net decrease in such Partnership Minimum Gain, determined in accordance with Regulations Section 1.704-2(d)(1), or (B) if such Holder would otherwise have an Adjusted Capital Account Deficit attributable solely to such Holder's Capital Account at the end of such taxable year, an amount sufficient to eliminate such Adjusted Capital Account Deficit. Allocations pursuant to the previous sentence shall be made in proportion to the respective amounts required to be allocated to the Holders pursuant thereto. The items to be so allocated shall be determined in accordance with Regulations Section 1.704-2. This Section 7.3(a) is intended to comply with the minimum gain chargeback requirement in Section 1.704-2(f) of the Regulations and shall be interpreted consistently therewith. To the extent permitted by such section of the Regulations and for purposes of this Section 7.3(a) only, each Holder's Adjusted Capital Account Deficit shall be determined prior to any other allocations with respect to such taxable year.

(b)

Partner Minimum Gain Chargeback. Except as otherwise provided in Regulations Section 1.704-2, if there is a net decrease in Partner Nonrecourse Debt Minimum Gain attributable to Partner Nonrecourse Debt during any taxable year, each Holder shall be specially allocated items of Down Trust income and gain for such taxable year (and, if necessary, subsequent taxable years) in an amount equal to such Holder's share, if any, of the net decrease in Partner Nonrecourse Debt Minimum Gain attributable to such Holder's Partner Nonrecourse Debt, as determined in accordance with Regulations Section 1.704-2. Allocations pursuant to the previous sentence shall be made in proportion to the respective amounts required to be allocated to each Holder pursuant thereto. The items to be so allocated shall be determined in accordance with Regulations Section 1.704-2. This Section 7.3(b) is intended to comply with the minimum gain chargeback requirements in such Regulations and shall be interpreted consistently therewith.

(c)

Qualified Income Offset. In the event any Holder unexpectedly receives any adjustments, allocations, or distributions described in Regulations Sections 1.704-1(b)(2)(ii)(d)(4), (5) or (6) with respect to such Holder's Capital Account, items of Down Trust income and gain shall be specially allocated to each such Holder in an amount and manner sufficient to eliminate, to the extent required by the Regulations, the Adjusted Capital Account Deficit of such Holder as quickly as possible; provided that an allocation pursuant to this Section 7.3(c) shall be made only if and to the extent that such Holder's Capital Account would have an Adjusted Capital Account Deficit after all other allocations provided for in this Trust Agreement have been tentatively made as if this Section 7.3(c) were not in this Trust Agreement. This Section 7.3(c) is intended to constitute a "qualified income offset" within the meaning of Regulations Section 1.704-1 and shall be interpreted consistently therewith.

(d)

Nonrecourse Deductions. Any Nonrecourse Deductions for any taxable year or other period shall be allocated to the Capital Accounts of the Holders in accordance with their respective Capital Accounts.

(e)

Partner Nonrecourse Deductions. Any Partner Nonrecourse Deductions for any taxable year (or portion thereof) of the Down Trust shall be allocated to the Holder who bears the economic risk of loss with respect to the Partner Nonrecourse Debt to which such Partner Nonrecourse Deductions are attributable, in accordance with Regulations Section 1.704-2.

(f)

Gross Income Allocation. In the event any Holder has an Adjusted Capital Account Deficit, items of Down Trust income and gain shall be specially allocated to the Capital Account of such Holder in an amount and manner sufficient to eliminate such Holder's Adjusted Capital Account Deficit as quickly as possible; provided that an allocation pursuant to this Section 7.3(f) shall be made only if and to the extent that such Holder's Capital Account would have an Adjusted Capital Account Deficit after all other allocations provided for in this Article 7 (other than this Section 7.3(f)) have been tentatively made as if this Section 7.3(f) were not in this Trust Agreement.

(g)

Loss Allocation Limitation. No allocation of Net Loss (or items thereof) shall be made to any Holder to the extent that such allocation would create or increase an Adjusted Capital Account Deficit with respect to such Holder.

(h)

Curative Allocations. The allocations set forth in this Section 7.3 (the "Regulatory Allocations") are intended to comply with certain requirements of the Regulations under Section 704 of the Code. Notwithstanding any other provision of this Trust Agreement (other than the Regulatory Allocations), the Regulatory Allocations shall be taken into account in allocating other Down Trust items of income, gain, loss, deduction and expense among the Holders so that, to the extent possible, the net amount of such allocations of other Down Trust items and the Regulatory Allocations shall be equal to the net amount that would have been allocated to the Holders pursuant to this Trust Agreement if the Regulatory Allocations had not been made.

Section 7.4

Transfer of or Change in Down MacroShares. The Depositor may use any convention or combination of conventions that it believes is reasonable for U.S. federal income tax purposes regarding the allocation of items of income, gain, loss, deduction and expense with respect to transferred Down MacroShares and redeemed Down MacroShares. A transferee who takes all or part of a Holder's Down MacroShares shall succeed to the Capital Account maintained in respect of the transferor Holder to the extent of such transfer; including where the transfer causes a termination of the Down Trust under Section 708(b)(1)(B) of the Code, in which case the Capital Account of the transferee and the Capital Accounts of the other Holders of Down MacroShares in the terminated Down Trust shall carry over to the new Down Trust that is formed, for U.S. federal income tax purposes, as a result of the termination.

Section 7.5

Tax Allocations. As of the end of each day, income, expense, deduction, gain or loss of the Down Trust, all as determined for U.S. federal income tax purposes, shall be allocated among the Holders pursuant to the following subsections solely for U.S. federal and other applicable tax purposes (both U.S. and non-U.S. taxes) as provided below. Such allocations shall be pro rata from short-term capital gain or loss and long-term capital gain or loss and operating income or loss recognized by the Down Trust. Such allocations shall be made, to the extent required, in a manner consistent with the principles of Section 7.2(b).

(a)

Except as provided in the second and third sentences of Section 7.5(b)(ii), items of ordinary income (such as interest income), deduction and expense (such as advisory fees and brokerage fees) shall be allocated in a manner consistent with the economic allocations described in Section 7.2.

(b)

Items of recognized capital gain or loss from the Down Trust's trading activities shall be allocated as follows:

(i)

There shall be established a tax basis account with respect to each Holder's shares in the Down Trust. The initial balance of each tax basis account shall be the amount contributed to the capital of the Down Trust for such shares.

(1)

Each tax basis account shall be increased by the amount of (I) any additional contributions made with respect to such Holder's shares in the Down Trust and (II) any taxable income or gain allocated to such Holder pursuant to Section 7.5(a) above and this Section 7.5(b);

(2)

Each tax basis account shall be decreased by the amount of (I) taxable expense, deduction or loss allocated to such Holder pursuant to Section 7.5(a) above and this Section 7.5(b) and (II) any distribution received by such Holder with respect to its Down MacroShares other than as a consequence of a partial redemption of Down MacroShares; and

(3)

When any Down MacroShare is redeemed, the tax basis account attributable to such redeemed Down MacroShare shall be eliminated.

(ii)

Items of recognized capital gain shall be allocated first to each Holder who has fully or partially redeemed its Down MacroShares on such day up to any excess of (A) the amount received upon such redemption over (B) the tax basis account attributable to the redeemed Down MacroShares in the Down Trust. If the aggregate amount of recognized capital gain to be so allocated to all Holders who have redeemed Down MacroShares on such day is less than the excess of all such amounts received upon redemption over all such tax basis accounts, then items of ordinary income shall be allocated first to all such Holders up to any excess of all such amounts. If the aggregate amount of recognized capital gain and ordinary income to be so allocated to all Holders who have redeemed Down MacroShares on such day is less than the excess of all such amounts received upon redemption over all such tax basis accounts, the entire amount of capital gain and ordinary income for such day shall be allocated among all such Holders in the ratio that each such Holder's allocable share of such excess bears to the aggregate excess of all such Holders who redeemed any of their Down MacroShares on such day.

(iii)

Items of recognized capital gain remaining after the allocations in subsection (ii) above shall be allocated among all Holders whose Capital Accounts are in excess of their tax basis accounts (after the adjustments in subsection (ii)) in the ratio that each such Holder's allocable share of such excess bears to all such Holders' excesses. If the aggregate amount of recognized capital gain to be so allocated is greater than the aggregate excess of all such Holders' Capital Accounts over all such tax basis accounts, the excess amount of gain shall be allocated among all Holders in the ratio that each Holder's Capital Account bears to all Holders' Capital Accounts.

(iv)

Items of recognized capital loss shall be allocated first to each Holder who has redeemed any of its Down MacroShares on such day up to any excess of (A) the tax basis account attributable to the redeemed Down MacroShare over (B) the amount received upon such redemption. If the aggregate amount of recognized capital loss to be so allocated to all Holders who have redeemed any Down MacroShares on such day is less than the aggregate excess of all such tax basis accounts over all such amounts received upon redemption, the entire amount of loss for such day shall be allocated among all such Holders in the ratio that each such Holder's excess bears to the aggregate excess of all such Holders who redeemed any of their Down MacroShares on such day.

(v)

Items of recognized capital loss remaining after the allocations in subsection (iv) above shall be allocated among the Holders whose tax basis accounts are in excess of their Capital Accounts (after the adjustments in subsection (iv)) in the ratio that each such Holder's allocable share of such excess bears to all such Holders' excesses. If the aggregate amount of loss to be so allocated is greater than the aggregate excess of all such tax basis accounts over all such Holders' Capital Accounts, the excess amount of recognized capital loss shall be allocated among all Holders in the ratio that each Holder's Capital Account bears to all Holders' Capital Accounts.

(vi)

The allocations of profit and loss to the tax basis accounts of Holders in respect of the Down MacroShares shall not exceed the allocations permitted under Subchapter K of the Code as determined by the Depositor in its sole and absolute discretion, whose determination shall be binding on the Holders.

(c)

The allocation of income, gain, loss, deduction and expense for U.S. federal income tax purposes set forth herein is intended to allocate such items so as to eliminate, to the extent possible, any disparity between a Holder's Capital Account and its tax basis account, consistent with principles set forth in Section 704(c) of the Code.

Section 7.6

Determination of Certain Matters. Notwithstanding anything express or implied to the contrary in this Trust Agreement, all matters concerning the computation of Capital Accounts and tax basis accounts, the allocation of Net Profit (and items thereof) and Net Loss (and items thereof), the allocation of items of income, gain, loss, deduction and expense for tax purposes, the adoption or modification of any accounting procedures, any adjustments to the books and records of the Down Trust and all matters related to liquidation and dissolution of the Down Trust shall be determined by the Depositor, in its sole and absolute discretion. Such determination shall be final and conclusive as to all Holders and be in accordance with the Code and Regulations. Notwithstanding anything expressed or implied in this Trust Agreement, in the event the Depositor shall determine, in its sole and absolute discretion, that it is prudent to modify the manner in which the Capital Accounts and tax basis accounts, or any debits or credits thereto, are computed in order to effectuate the intended economic sharing arrangement of the Holders, the Depositor may make such modification. Allocations of Net Profit and Net Loss to a Holder's Capital Account shall be made for each day as soon as practicable thereafter.

Section 7.7

No Deficit Makeup. Notwithstanding anything herein to the contrary, upon the liquidation of the Down Trust, no Holder shall be required to make any contribution to the Down Trust in respect of any deficit in such Holder's Capital Account.

Section 7.8

U.S. Partnership Tax Treatment. It is the intent of the Holders and the Depositor that the Down Trust be governed by the applicable provisions of Subchapter K, of Chapter 1, of the Code. The Depositor may file such forms and make such elections as the Depositor deems appropriate to effect such intent.

Section 7.9

Definitions. For the purposes of this Trust Agreement, unless the context otherwise requires:

(b)

Subject to the provisions of this Section 13.8, the Trustee may be appointed, removed or replaced without cause at any time by the Depositor, upon written notice, or with cause upon the occurrence of a Trustee Termination Event; provided, however, that the Trustee shall not be removed in accordance with this Section 13.8 until a successor Trustee possessing the qualifications to act as Trustee and willing and able to make the representations contained in Section 3.2 (a "Successor Trustee") has been appointed by the Depositor and has accepted such appointment by written instrument executed by such Successor Trustee and delivered to the Depositor.

(c)

Any Trustee may resign hereunder by an instrument in writing signed by the Trustee and delivered to the Depositor, the Administrative Agent and each Registered Owner, which shall become effective on the date specified in such instrument; provided, however, that no such resignation of a Trustee shall become effective:

until a Successor Trustee has been appointed and has accepted such appointment by instrument executed by such Successor Trustee and delivered to the Down Trust, the Depositor, the Administrative Agent and the resigning Trustee; or

(ii)

until the assets of the Down Trust have been completely liquidated and the proceeds thereof distributed to the Holders.

If no Successor Trustee shall have been appointed and accepted such appointment within thirty (30) days after delivery to the Depositor, the Administrative Agent and the Down Trust of an instrument of resignation, the resigning Trustee may petition at the expense of the Down Trust any court of competent jurisdiction for appointment of a Successor Trustee. Such court may thereupon, after prescribing such notice, if any, as it may deem proper, appoint a Successor Trustee.

(d)

No Trustee shall be liable for anything that occurs after it has ceased to act in such capacity, including, without limitation, the acts or omissions to act of any Successor Trustee; provided, that such resigning or terminated Trustee shall remain liable for any actions taken by it prior to its termination or resignation as a result of which it would be liable to the Down Trust pursuant to Section 13.1(c).

Section 13.9

Successor Trustee.

(a)

Any Successor Trustee appointed as provided in Section 13.8 shall execute, acknowledge and deliver to the Depositor and to its predecessor Trustee an instrument in a form acceptable to the Depositor accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor Trustee shall become effective and such Successor Trustee, without any further act, deed or conveyance, shall become fully vested with all the rights, powers, duties and obligations of its predecessor hereunder, with the like effect as if originally named as Trustee herein. The predecessor Trustee shall deliver to the Successor Trustee all documents and statements held by it hereunder, and the Depositor and the predecessor Trustee shall execute and deliver such instruments and do such other things as may reasonably be required for fully and certainly vesting and confirming in the Successor Trustee all such rights, powers, duties and obligations within thirty days of execution of such instrument.

(b)

No Successor Trustee shall accept appointment as provided in this Section 13.9 unless at the time of such acceptance such Successor Trustee is eligible under the provisions of Section 13.7 and makes in the instrument of acceptance delivered pursuant to clause (a) of this Section 13.9 the representations and warranties contained in Section 3.2 hereof.

(c)

Upon acceptance of appointment by a Successor Trustee as provided in this Section 13.9, such Successor Trustee shall provide prompt notice of its succession hereunder to the Depositor, and the Depositor shall file a Form 8-K with the SEC disclosing such succession.

(d)

Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all the corporate trust business of the Trustee shall be the successor of the Trustee hereunder without the execution or filing of any paper or any further act on the part of any of the parties hereto; provided, however, that such corporation shall be otherwise qualified and eligible under this Article 13, including without limitation, Section 13.7 hereof. The Trustee shall promptly furnish to the Depositor and the Administrative Agent a notice of any merger or consolidation to which the Trustee is a party.

Section 13.11

Appointment of Co-Trustee or Separate Trustee.

(a)

Notwithstanding any other provisions of this Trust Agreement, the Trustee shall have the power and may execute and deliver all instruments to appoint, at any time, one or more Persons to act as a co-trustee or co-trustees, or a separate trustee or separate trustees, of all or any part of the Trust Assets, and to vest in such Person or Persons, in such capacity and for the benefit of the Holders of the Down MacroShares, such title to the Trust Assets or any part thereof and, subject to the other provisions of this Section 13.11, such powers, duties, obligations, rights and trusts as the Trustee may consider necessary or desirable, for the purpose of meeting any legal requirements of any jurisdiction in which any part of the Trust Assets may at the time be located; provided, that such co-trustee or co-trustees, or separate trustee or separate trustees, shall also assume the rights, duties and obligations of the Trustee under the Down Trust Agreement; provided, further, that the Trustee shall exercise due care in the appointment of any co-trustee or separate trustee. Each co-trustee or separate trustee hereunder shall be required to meet the terms of eligibility for a successor trustee under Section 13.8 and Section 13.9. No notice to Holders of the Down MacroShares of the appointment of any co-trustee or separate trustee shall be required under this Section 13.11; provided, that the Trustee shall provide notice of each such appointment to the Depositor and the Administrative Agent.

(b)

Every co-trustee and separate trustee shall, to the extent permitted by law, be appointed and act subject to the following provisions and conditions:

(i)

all rights, powers, duties and obligations conferred or imposed upon the Trustee shall be conferred or imposed upon and exercised or performed by the Trustee and such co-trustee or separate trustee jointly (it being understood that such co-trustee or separate trustee shall not be authorized to act unless the Trustee joins in such act) except to the extent that under any laws of any jurisdiction in which any particular act or acts are to be performed the Trustee is incompetent or unqualified to perform such act or acts, in which event such rights, powers, duties and obligations (including the holding of title to the Trust Assets or any portion thereof in any such jurisdiction) shall be exercised or performed singly by such co-trustee or separate trustee, but solely at the direction of the Trustee;

(ii)

no co-trustee or separate trustee hereunder shall be personally liable by reason of any act or omission of any other trustee hereunder; and

(iii)

the Trustee may at any time accept the resignation of or remove any co-trustee or separate trustee.

(c)

Any notice, request or other writing given to the Trustee shall be deemed to have been given to each of the then co-trustees and separate trustees as effectively as if given to each of them. Every instrument appointing any co-trustee or separate trustee shall refer to this Trust Agreement and the conditions of this Article 13. Upon its acceptance of the trusts conferred by its instrument of appointment, each co-trustee and separate trustee shall be vested with the estates or property specified in such instrument, either jointly with the Trustee or separately, as may be provided therein, subject to all of the provisions of this Trust Agreement, specifically including every provision of this Trust Agreement relating to the conduct of, affecting the liability of, or affording protection to the Trustee. Every such instrument shall be filed with the Trustee.

(d)

Any co-trustee or separate trustee may at any time appoint the Trustee its agent or attorney-in-fact with full power and authority, to the extent not prohibited by law, to do any lawful act under or in respect to this Trust Agreement on its behalf and in its name. If any co-trustee or separate trustee shall become incapable of acting, resign or be removed, all of its estates, properties, rights, remedies and trusts under or in respect to this Trust Agreement shall vest in and be exercised by the Trustee, to the extent permitted by law, without the appointment of a new or successor trustee.

Section 13.12

Books, Records; Taxes; Audit.

(a)

The Trustee shall keep proper books of record and account of all the transactions under this Trust Agreement at its Corporate Trust Office or such office as it may subsequently designate upon notice to the other parties hereto. The books and records of the Trustee shall be open to inspection by any Person who establishes to the Trustee's reasonable satisfaction that it is a Beneficial Owner upon reasonable advance notice at all reasonable times during the usual business hours of the Trustee. The Administrative Agent shall keep proper records of all Paired Optional Redemptions and Paired Issuances effected at any time at its Business Office. Such records shall be open to inspection by any Person who establishes to the Administrative Agent's reasonable satisfaction that it is a Beneficial Owner upon reasonable advance notice at all reasonable times during the usual business hours of the Administrative Agent. Such records shall be preserved by the Trustee or the Administrative Agent, as applicable, for so long as the Depositor may direct.

(b)

The Trustee shall provide the Depositor such financial and other information regarding the operation of the Down Trust as may be required for the Depositor to prepare such reports and filings required under the federal securities laws as required under Section 8.2. Unless otherwise required by applicable law or regulation, the Depositor shall be responsible for any certification of any such reports or the contents thereof; provided, that the Trustee shall make such representations to the Depositor with respect to information within the Trustee's control as shall be required for the Depositor to make such certification.

(c)

The Depositor shall prepare or cause to be prepared, and the Trustee shall sign (if it is determined that the Trustee's signature is required thereon) and timely file any tax returns required to be filed by the Down Trust. The Depositor shall also prepare or cause to be prepared all tax information required by law to be distributed to Holders of the Down MacroShares and shall cause such information to be distributed to Holders as soon as reasonably practicable following the close of the taxable year. The Trustee, the Calculation Agent and the Administrative Agent, upon request, shall each furnish the Depositor with any information known to it that may be reasonably required in connection with the preparation of such duties set forth in the preceding two sentences.

(d)

The Depositor (or another Holder designated by the Depositor) shall be the "tax matters partner" of the Down Trust for U.S. federal income tax purposes and is authorized to act as the "tax matters partner" of the Down Trust or in any similar capacity under state, local or foreign law. Pursuant to Section 6230(e) of the Code, upon receipt of notice from the IRS of the beginning of an administrative proceeding with respect to the Down Trust the tax matters partner shall furnish the IRS with the name, address, and taxpayer identification number of each of the Holders; provided, however, that such information is provided to the Down Trust by the Holders.

The tax matters partner is authorized, but not required:

(i)

to enter into any settlement with the IRS with respect to any administrative or judicial proceedings for the adjustment of Down Trust items required to be taken into account by a Holder for income tax purposes (such administrative proceedings being referred to as a "tax audit" and such judicial proceedings being referred to as "judicial review"), and in the settlement agreement the tax matters partner may expressly state that such agreement shall bind all Holders, except that such settlement agreement shall not bind any Holder (i) who (within the time prescribed pursuant to the Code and Regulations) files a statement with the IRS providing that the tax matters partner shall not have the authority to enter into a settlement agreement on behalf of such Holder; or (ii) who is a "notice partner" (as defined in Section 6231(a)(8) of the Code) or a member of a "notice group" (as defined in Section 6223(b)(2) of the Code);

(ii)

in the event that a notice of a final administrative adjustment at the Down Trust level of any item required to be taken into account by a Holder for tax purposes (a "final adjustment") is mailed to the tax matters partner, to seek judicial review of such final adjustment, including the filing of a petition for readjustment with the Tax Court or the filing of a complaint for refund with the United States Claims Court or the District Court of the United States for the district in which the Down Trust's principal place of business is located;

(iii)

to intervene in any action brought by any other Holder for judicial review of a final adjustment;

(iv)

to file a request for an administrative adjustment with the IRS and, if any part of such request is not allowed by the IRS, to file an appropriate pleading (petition or complaint) for judicial review with respect to such request;

(v)

to enter into an agreement with the IRS to extend the period for assessing any tax which is attributable to any item required to be taken account of by a Holder for tax purposes, or an item affected by such item; and

(vi)

to take any other action on behalf of the Holders or the Down Trust in connection with any tax audit or judicial review proceeding to the extent permitted by applicable law or regulations.

The taking of any action and the incurring of any expense by the tax matters partner in connection with any such proceeding, except to the extent required by law, is a matter in the sole and absolute discretion of the tax matters partner and the provisions relating to indemnification of the Trustee set forth in Section 13.6 of this Trust Agreement shall apply mutatis mutandis to the tax matters partner in its capacity as such, including if the Depositor designates another Holder to serve as tax matters partner.

(e)

In no event shall the Trustee, the Depositor or the Administrative Agent be personally liable for any taxes or other governmental charges imposed upon or in respect of the Down MacroShares under any present or future law of the United States of America or imposed by any taxing authority having jurisdiction over the Down Trust. For all such taxes and charges and for any expenses, including counsel's fees, which the Trustee or the Administrative Agent may sustain or incur with respect to such taxes or charges, the Trustee or the Administrative Agent shall be reimbursed and indemnified out of the assets of the Down Trust and the payment of such amounts shall be secured by a lien on the Down Trust. Any payments by the Trustee or the Administrative Agent shall be subject to withholding regulations then in force. This paragraph shall survive notwithstanding any termination of this Trust Agreement and the Down Trust or the resignation or removal of the Trustee or the Administrative Agent. If sufficient funds are not on deposit in the Fee Payment Account to reimburse the Trustee or the Administrative Agent for any taxes paid by either of them on behalf of the Down Trust, the Depositor shall reimburse the Trustee and the Administrative Agent therefor.

(f)

The accounts of the Down Trust shall be audited, as required by law and as may be directed by the Depositor, by Independent certified public accountants designated from time to time by the Depositor and the cost of such audit shall be borne by the Down Trust pursuant to Section 5.3 hereof. The report of such accountants shall be furnished by the Administrative Agent to any Beneficial Owner upon request.

Section 13.13

Trustee May Enforce Claims Without Possession of Down MacroShares. All rights of action and claims under this Trust Agreement or the Down MacroShares may be prosecuted and enforced by the Trustee without the possession of any of the Down MacroShares or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee. Any recovery of judgment shall, after provision for payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Down MacroShares in respect of which such judgment has been obtained.

Section 13.14

Suits for Enforcement. If a Termination Trigger or a Trustee Termination Event occurs and is continuing, the Trustee (or the Depositor, in the case of a Trustee Termination Event) in its discretion may proceed to protect and enforce its rights and the rights of the Holders of the Down MacroShares under this Trust Agreement by a suit, action or proceeding in equity or at law or otherwise, whether for the specific performance of any covenant or agreement contained in this Trust Agreement, in aid of the execution of any power granted in this Trust Agreement or for the enforcement of any other legal, equitable or other remedy as the Trustee (or the Depositor, in the case of a Trustee Termination Event), being advised by counsel, shall deem most effectual to protect and enforce any of the rights of the Holders of the Down MacroShares. The Trustee or the Depositor, as the case may be, shall be reimbursed by the Down Trust for all expenses incurred by it in so protecting and enforcing its rights and the rights of the Holders of the Down MacroShares hereunder and the Trustee shall have a lien on the Trust Assets securing repayment of such expenses.

Section 13.15

Maintenance of Office or Agency. The Trustee will maintain at its expense an office or agency (the "Corporate Trust Office") where notices and demands to or upon the Trustee in respect of the Down MacroShares and this Trust Agreement may be served. The Corporate Trust Office shall initially be located at Two World Financial Center, 225 Liberty Street, New York, New York 10281. The Trustee will give prompt notice to the Depositor and to Registered Owners of the Down MacroShares of any change in the location of the Corporate Trust Office.

Subject to clause (a) of this Section 15.1, this Trust Agreement may be amended from time to time with the written consent of the Depositor, the Administrative Agent and the Trustee, but without the consent of any Holder of Down MacroShares, (i) to cure any ambiguity or to correct or supplement any provision which may be defective or inconsistent with any other provision of this Trust Agreement or the Down Trust Agreement, (ii) to modify any provision of or add a provision to this Trust Agreement to conform it to the description of the terms of the Down MacroShares contained in the Prospectus, (iii) to add to the covenants, restrictions or obligations of any entity under this Trust Agreement for the benefit of the Holders of the Down MacroShares or to modify any provisions of this Trust Agreement in any manner that does not adversely affect any Holder of Paired Shares in any material respect, (iv) to evidence and provide for the acceptance of appointment hereunder of a Successor Trustee, a successor Administrative Agent or any successor Marketing Agent, (v) to modify the procedures for effecting Paired Issuances and Paired Optional Redemptions set forth herein in connection with an amendment of the Participants Agreement entered into among the Trustee, the Down Trustee, the Administrative Agent and one or more Authorized Participants, (vi) subject to compliance with clause (a) of this Section 15.1, to increase or decrease the aggregate number of Down MacroShares and Up MacroShares that constitute a MacroShares Unit, (vii) to modify the rules for acquiring Eligible Treasuries that are set forth in Section 6.8 hereof, and (viii) to comply with any requirements imposed by the Code, or any federal or state securities laws; provided, that an opinion in form and substance satisfactory to the Depositor that such amendment will not cause the Down Trust to be treated as an association taxable as a corporation must be delivered in connection with any amendment referenced in the foregoing clause (iii) and clause (vii); provided, further, that no amendment of this Trust Agreement may be made if it would have the effect of causing the Down Trust to be required to register as an investment company under the Investment Company Act or to be regulated as a commodity pool under the CEAct. The Trustee may, but shall not be obligated to, enter into any amendment which affects the Trustee's rights, duties or immunities under this Trust Agreement or otherwise.

(c)

Subject to clause (a) of this Section 15.1, this Trust Agreement may also be amended from time to time with the written consent of the Depositor, the Administrative Agent and the Trustee and the written consent of the Holders of Down MacroShares evidencing not less than a majority of the Down Aggregate Par Amount, for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Trust Agreement or of modifying in any manner the rights of the Holders of the Down MacroShares; provided, that the Down Trust Agreement shall be amended in an identical manner in accordance with the amendment provisions thereof, and until the requisite consent for such amendment has been obtained, any amendment to this Trust Agreement will not become effective; provided, further still, that, without the written consent of each Holder of the Down MacroShares and the Down MacroShares that would be adversely affected thereby, no amendment may (i) modify the amount or timing of any distributions that are required to be made on the Down MacroShares; or (ii) reduce the percentage of Holders that are required to consent to any of the foregoing amendments; and provided, further still, that the use of the price of the Light Sweet Crude Oil Futures Contract from a Substitute Oil Price Provider or the spot price of West Texas Intermediate Crude Oil or of Light Louisiana Sweet Crude Oil generated by the Dow Jones Energy Service as the Substitute Reference Oil Price shall not require the consent of any of the Holders.

(d)

Subject to clause (a) of this Section 15.1, this Trust Agreement may be amended at any time prior to the initial Paired Issuance with the written consent of the Depositor, the Administrative Agent and the Trustee and the written consent of each holder of Founders' Shares for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of hereof.

(e)

The Depositor may amend the Income Distribution Agreement or the Settlement Contracts in any manner that is otherwise not prohibited by the terms of clause (a) of this Section 15.1, as long as the Trustee is not adversely affected in any way by any such amendment.

(f)

In considering, reviewing and/or evaluating any proposed amendment or a request for a consent from the Trustee pursuant to the provisions of this Section 15.1 or otherwise under this Trust Agreement, the Trustee may in its discretion seek or obtain advice or an Opinion of Counsel from counsel of its choice with respect to any such proposed amendment or consent and its compliance with the terms of this Trust Agreement and Requirements of Law as it pertains to the Down Trust, the parties to the Trust Agreement and any other related parties. The fees and expenses of counsel selected by the Trustee, whether or not an Opinion of Counsel is rendered, shall be promptly paid out of the assets of the Down Trust or reimbursed to the Trustee. The Trustee may rely on such advice of counsel or an Opinion of Counsel in taking any action or refraining from taking any action with respect to any such amendment or request for a consent from the Trustee. The Trustee shall in accordance with the foregoing be afforded all rights, remedies, protections, indemnifications and limitations of liability set forth in this Trust Agreement including, without limitation, those set forth in Article 13 hereof, and nothing in this Section 15.1 shall alter the standard of care specified in Article 13 hereof as it pertains to the Trustee.

(g)

Promptly after the execution of any amendment or consent pursuant to this Section 15.1, the Depositor shall prepare and file a Form 8-K with the SEC setting forth the provisions of such amendment.

(h)

Where the consent of Holders is required under this Section 15.1 in order to amend this Trust Agreement, it shall be sufficient if such consent approves the substance of the proposed amendment; the particular form of such amendment need not be approved. The manner of obtaining such consents and of evidencing the authorization of the execution thereof by Holders of the Down MacroShares shall be subject to such reasonable requirements as the Trustee may prescribe.

(i)

Holders evidencing not less than a majority of the Down Aggregate Par Amount may waive any default by the Depositor, the Trustee, or the Administrative Agent in the performance of their obligations hereunder and its consequences, except the failure to make any distributions required to be made to Holders of the Down MacroShares or to make any Down Income Distribution Payment or any Down Settlement Payment. Upon any such waiver of a past default, such default shall cease to exist, and any default arising therefrom shall be deemed to have been remedied for every purpose of this Trust Agreement. No such waiver shall extend to any subsequent or other default or impair any right consequent thereon except to the extent expressly so waived.

(j)

In the event that the NYMEX License terminates, the Administrative Agent and the Depositor shall seek to enter into a new license with the NYMEX on terms that are mutually acceptable to the Administrative Agent, the Depositor and NYMEX. If no such license is successfully negotiated with NYMEX, the Administrative Agent and the Depositor shall seek to identify an alternate source of NYMEX settlement prices and to arrange to obtain such settlement prices from such source for the purpose of calculating Up and Down Underlying Value and Quarterly and Final Distributions. If the Administrative Agent and the Depositor are unable to identify such a source, they shall seek to enter into a licensing agreement with the Down Jones Energy Service for the West Texas Intermediate Crude Oil or Light Sweet Louisiana Crude Oil. In the event that the Substitute Oil Price Provider is a publicly-accessible source of NYMEX settlement prices, the intra-day indicative Per Share Underlying Value of the Down Trust shall be based upon a futures contract referencing crude oil that is selected by the Administrative Agent based upon its similarity, in the commercially reasonable judgment of the Administrative Agent, to the Light Sweet Crude Oil Futures Contract; provided that the Up and Down Underlying Values will continue to be calculated based upon the Light Sweet Crude Oil Futures Contract. Neither the Administrative Agent nor the Depositor shall be liable hereunder for the failure to identify a Substitute Oil Price Provider or to enter into a Substitute Reference Price Licensing Agreement.

Section 15.2

Registration (Initial and Continuing) of Down MacroShares; Certain Securities Law Filings. The Depositor agrees to (i) prepare and file the Registration Statement with the SEC under the Securities Act, and take such action as is necessary from time to time to qualify the Down MacroShares for offering and sale under the federal securities laws of the United States, including the preparation and filing of amendments of and supplements to such Registration Statement, (ii) promptly notify the Trustee and the Administrative Agent of any such amendment of or supplement to the Registration Statement and of any order preventing or suspending the use of the Prospectus included therein, (iii) provide the Trustee and the Administrative Agent from time to time with copies, including copies in electronic form, of the Prospectus, in such quantities as the Trustee and the Administrative Agent may reasonably request, (iv) prepare and file any periodic reports or updates that may be required under the Exchange Act, as specified in Section 8.2 hereof, and (v) take such action as is necessary from time to time to register or qualify the Down MacroShares for offering and sale under the securities or blue sky laws of those states of the United States or other jurisdictions as the Depositor may select or as may be necessary to continue that registration or qualification in effect for so long as the Depositor determines that the Down Trust shall continue to offer or sell Down MacroShares in that jurisdiction. Registration charges, blue sky fees, printing costs, mailing costs, attorney's fees, and other miscellaneous out-of-pocket expenses shall be borne by the Down Trust in the manner provided for in Section 5.3.

Section 15.3

Prospectus Delivery. The Administrative Agent shall, if required to do so under the federal securities laws of the United States, deliver at the time of issuance of any Down MacroShares in any manner permitted by such laws, a copy of the Prospectus, as most recently furnished to the Administrative Agent by the Depositor, to each person submitting a Creation Order. The Administrative Agent shall also, if required to do so under the federal securities laws of the United States, deliver in conjunction with any marketing or computational materials, in any manner permitted by such laws, a copy of the Prospectus, as most recently furnished to the Administrative Agent by the Depositor.

Not later than the Closing Date, the Depositor shall file a financing statement covering the interest of the Down Trustee, on behalf of the Up Trust, in the Trust Assets which shall secure the obligations of the Down Trust to the Down Trust under the Income Distribution Agreement and the Settlement Contracts. The Depositor shall deliver to the Trustee file-stamped copies of, or filing receipts for, any document recorded, registered or filed as provided above, as soon as available following such recording, registration or filing.

(b)

Within 30 days after the Depositor makes any change in its name, identity or corporate structure which would make any financing statement or continuation statement filed in accordance with paragraph (a) above seriously misleading within the meaning of Section 9-402(7) (or any comparable provision) of the UCC, the Depositor shall give the Trustee notice of such change and shall file such financing statements or amendments as may be necessary to continue the perfection of the Down Trust's security interest in the Trust Assets and the proceeds thereof.

(c)

The Depositor shall give the Trustee prompt notice of any relocation of its principal executive offices or of any office from which it performs its duties hereunder or keeps records concerning this transaction. If, as a result of any such relocation, the applicable provisions of the UCC require the filing of any new financing statement or of any amendment to any previously filed financing or continuation statement, the Depositor shall file such financing statements or amendments as may be necessary to perfect or to continue the perfection of the Down Trust's security interest in the Trust Assets and the proceeds thereof. The Depositor shall at all times maintain its principal executive offices and each office from which it performs its duties hereunder within the United States.

Section 15.5

Section 15.7

MacroShares Licensing Agreement. On the Closing Date, the Down Trust shall enter into the MacroShares Licensing Agreement with MacroMarkets LLC, the Administrative Agent and the Up Trust. Under such MacroShares Licensing Agreement, MacroMarkets LLC shall be entitled to the receipt of the Down Licensing Fee, which shall be payable to MacroMarkets LLC in arrears on each Distribution Date in accordance with Section 5.4 hereof.

EXHIBIT H

AFFILIATED PERSON VERIFICATION GUIDELINES

Acquisitions of Eligible Treasuries

(a)

Subject to a best execution requirement pursuant to Section 6.8, the Administrative Agent may direct the Trustee to acquire Eligible Treasuries from Authorized Participants or from an Affiliated Person of an Authorized Participant (each, an "AP Affiliated Person," and, such transaction, an "AP Acquisition") only in the event that the offers of such AP Affiliated Person are within the Range of the Best Yield, as defined below.

(b)

The available market yields for purposes of calculating Best Yield will be based, for trades in Eligible Treasury Securities, on prices displayed on the applicable Bloomberg screen and, for trades in Eligible Treasury Repurchase Agreements, general market offered yields obtained from Bloomberg or another third-party service provider for Eligible Treasury Repurchase Agreements.

(c)

For purposes of this Exhibit H, the "Best Yield" means the average of the five highest yields offered by sellers with whom the Administrative Agent has a trading agreement and the "Range" is the difference between (i) the greater of (x) 0.10% and (y) 2% times the Best Yield, which is the bottom of the Range, and (ii) the Best Yield, which is the top of the Range.

In-Kind Redemptions

Any "in-kind" Paired Optional Redemption by an AP Affiliated Person will be executed in accordance with Section 6.1(d) (an "AP In-Kind Redemption").

Record Retention

(a)

For each AP Acquisition, the Administrative Agent will retain a print-out of the Bloomberg screen at the time each Eligible Treasury Security purchase order is placed and a print-out of the Bloomberg or other pricing service yield information at the time each Eligible Treasury Repurchase Agreement purchase order is placed (as well as, in each case, the corresponding trade ticket information relating to such AP Acquisition). Such print outs will include all available offers at the time the applicable order was placed, as well as the time, date, amount, counterparty and implied yield or price of each transaction.

H-1

(b)

For each AP Acquisition that was effected at a yield that was lower than the Best Yield, the Administrative Agent will record, contemporaneously with the transaction, why the AP Acquisition was effected at a yield that was lower than the Best Yield.

(c)

For each AP In-Kind Redemption, the Administrative Agent will retain in its books and records, the date of the transaction, the name of the redeeming Authorized Participant, the Eligible Treasury Securities that were delivered in the redemption and the Eligible Treasury Securities that were on deposit in the Down Trust immediately prior to the In-Kind Redemption (including on the relevant acquisition date), and the Eligible Treasury Securities which remained on deposit in the Down Trust after such redemption.

(d)

The information recorded by the Administrative Agent pursuant to this Section 3, will be retained by the Administrative Agent for a period of one year from the date each AP Acquisition and AP In-Kind Redemption took place.

Independent Verification Procedures

(a)

At the conclusion of each calendar quarter, the Trustee, acting as a verification agent (the "Verification Agent"), shall select, randomly and without notifying the Administrative Agent, one Business Day in each week of the preceding quarter, and

(i)

if any AP Acquisitions occurred on such day, the Verification Agent will verify that (1) the Administrative Agent properly identified and recorded all such AP Acquisitions; and (2) no transactions outside of the Range were executed with any AP Affiliated Person; and

(ii)

if any AP In-Kind Redemptions occurred on such day, the Verification Agent will verify that (1) the Administrative Agent properly identified and recorded all such AP In-Kind Redemptions and (2) that the AP In-Kind Redemptions were executed in accordance to Section 2, herein.

(b)

In the event that the Verification Agent has identified an AP Acquisition outside of the Range or an AP In-Kind Redemption that violates Section 6.1(d) (each such transaction, a "Prohibited Transaction"), the Verification Agent shall review all the information retained by the Administrative Agent in accordance with Sections 3(a) or 3(b), hereof, as applicable, during,

(i)

the six-month period that preceded such Prohibited Transaction and

(ii)

the calendar quarter that follows the Prohibited Transaction,

H-2

to determine whether any additional Prohibited Transactions occurred.

Remedy for Prohibited Transactions

(a)

In the event that the Verification Agent identifies any Prohibited Transaction, the Verification Agent will notify the Depositor and the Administrative Agent, and the Administrative Agent will be required to pay to the Down Trust, for each such Prohibited Transaction within thirty day of such notification,

(i)

if the Prohibited Transaction was an AP Acquisition, the difference between (x) the Best Yield which the Down Trust would have obtained had such transaction occurred, less the Range and (y) the yield actually obtained in the Prohibited Transaction; and

(ii)

if the Prohibited Transaction was an AP In-Kind Redemption, an amount equal to the yield to maturity of the Eligible Treasury Securities which were delivered minus the yield to maturity of the Eligible Treasury Securities which should have been delivered to the redeeming AP Affiliated Person.

These procedures will apply to transactions between the Down Trust and any Authorized Participant or any Affiliated Person with regard to the such Authorized Participant, to the extent that such Authorized Participant meets the definition of "principal underwriter" with regard to the Down Trust that is set forth in Section 2(a)(29) of the Investment Company Act of 1940, as amended and as interpreted by the SEC and its Staff.
