MACROSHARES PARTICIPANTS AGREEMENT

Exhibit 4.3

This agreement (the "Participants Agreement"), dated as of April [ ], 2008 is hereby entered into by and among the parties listed from time to time on Schedule I attached hereto (each, an "Authorized Participant" and, collectively, the "Authorized Participants"), the trustees (each, a “Trustee” and collectively, the “Trustees”) listed from time to time on Schedule II attached hereto not in its individual capacity but solely acting as trustee on behalf of the trusts (each, a “MacroShares Trust” and, collectively, the “MacroShares Trusts”) also listed on such Schedule II, the depositor entities (each, a "Depositor" and, collectively, the “Depositors”) listed from time to time on Schedule III attached hereto, and MacroMarkets LLC, not in its individual capacity but solely as administrative agent of the Paired Trusts (the "Administrative Agent"). Each Authorized Participant will also execute, in the appropriate signature blocks provided in Attachment A and B, the Applicable Creation Procedures and Applicable Redemption Procedures for each set of Paired Trusts for which it acts as an Authorized Participant.

PREAMBLE

Each MacroShares Trust will be formed pursuant to a trust agreement (each, a “MacroShares Trust Agreement” and, collectively, the “MacroShares Trust Agreements”) entered into among the applicable Trustee, the applicable Depositor, the Administrative Agent, MACRO Financial, LLC, as marketing agent (a “Marketing Agent”) and the additional marketing agents (each, also a “Marketing Agent” and, collectively, the “Marketing Agents”) listed from time to time on Schedule IV attached hereto. Each MacroShares Trust will either be an "Up Trust" which will issue "Up MacroShares" or a "Down Trust" which will issue "Down MacroShares" (together with the Up MacroShares, the "MacroShares"). Each related Up MacroShares Trust and Down MacroShares Trust are together referred to herein as the "Paired Trusts". The Up MacroShares and Down MacroShares issued by a set of Paired Trusts are referred to herein as the "Paired MacroShares".

Each issuance of MacroShares will be offered pursuant to a prospectus (as amended and restated from time to time each, a "Prospectus"), the details of which are listed on Schedule V attached hereto, that has been filed in connection with a registration statement on Form S-1 (as amended and restated from time to time, each a "Registration Statement" and collectively, the "Registration Statements"), filed with the Securities and Exchange Commission ("SEC").

In accordance with this Participants Agreement, the applicable Trustee, acting together with the Administrative Agent on behalf of the applicable Paired Trusts, may create or redeem the applicable Paired MacroShares in units of 50,000 Up MacroShares and 50,000 Down MacroShares (each such unit, a "MacroShares Unit") at the instructions of the applicable Authorized Participant and in accordance with the applicable procedures set forth herein.

Under the applicable MacroShares Trust Agreements, the Administrative Agent will instruct the applicable Trustee to issue the applicable MacroShares Units to, and redeem the applicable MacroShares Units from, the applicable Authorized Participants, only through the facilities of DTC or a successor depository. Each Authorized Participant may create or redeem MacroShares Units only to the extent it is an authorized participant for the Paired Trusts issuing such MacroShares Units. The entities that are Authorized Participants with respect to each existing set of Paired Trusts are specified in Schedule I attached hereto.

In exchange for the deposit of cash equal to the aggregate purchase price specified herein and in the applicable MacroShares Trust Agreement, an Authorized Participant may create one or more MacroShares Units. In exchange for a deposit of the applicable Paired MacroShares constituting one or more MacroShares Units, an Authorized Participant may redeem one or more such MacroShares Units for cash and/or Eligible Treasuries as further described herein. This Participants Agreement sets forth the specific procedures by which the applicable Authorized Participant may create and redeem MacroShares Units for each set of Paired Trusts.

Because new MacroShares can be created and issued on an ongoing basis on any Business Day prior to an Early Termination Date or the Final Scheduled Termination Date for the applicable Paired Trusts, a "distribution," as such term is used in the Securities Act of 1933, as amended ("Securities Act"), may be occurring at any time from the applicable Closing Date through such Early Termination Date or Final Scheduled Termination Date. Each Authorized Participant is cautioned that some of its activities may result in its being deemed a participant in a distribution which would render it a statutory underwriter and subject it to the prospectus-delivery requirements and the liability provisions of the Securities Act. Each Authorized Participant should review the "Plan of Distribution" portion of the Applicable Prospectus and consult with its own counsel in connection with entering into this Participants Agreement and placing a Creation Order or a Redemption Order (each as defined herein).

Capitalized terms used but not defined in this Participants Agreement shall have the meanings assigned to such terms in the MacroShares Trust Agreements of the applicable Paired Trusts. To the extent there is a conflict between any provision of this Participants Agreement and the provisions of such Trust Agreements, the provisions of this Participants Agreement will govern insofar as they relate to the Applicable Procedures (as defined below).

To give effect to the foregoing premises and in consideration of the mutual covenants and agreements set forth below, the parties hereto agree as follows:

(b)

To redeem MacroShares constituting one or more MacroShares Units for cash or for cash and/or Eligible Treasuries, Authorized Participants must follow the procedures for redemption set forth in Section 4 of this Participants Agreement and the procedures for the applicable set of Paired Trusts described in Attachment B attached hereto (the "Applicable Redemption Procedures" and, together with the Creation Procedures, the "Applicable Procedures"), as each may be amended, modified or supplemented from time to time.

(b)

Each of the MacroShares Trust hereby agree to indemnify and hold harmless, severally and not jointly, each Person which acts as an Authorized Participant for such MacroShares Trust, its respective subsidiaries, affiliates, directors, officers, employees and agents, and each person, if any, who controls such persons within the meaning of Section 15 of the Securities Act (each, a "Trust Indemnified Party") from and against any losses, liabilities, damages, costs and expenses (including reasonable attorneys' fees) incurred by such Trust Indemnified Party as a result of (i) any breach by a MacroShares Trust of any provision of this Participants Agreement that relates to such MacroShares Trust, (ii) any failure on the part of a MacroShares Trust to perform any of its obligations set forth in this Participants Agreement or (iii) any untrue statement or alleged untrue statement of a material fact contained in the applicable Prospectuses as originally filed with the SEC or in any amendment thereof or supplement thereto, or arising out of or based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except those statements in such Prospectuses based on information furnished in writing by or on behalf of the applicable Authorized Participant expressly for use in the applicable Prospectuses.

(c)

This Section 10 shall not apply to the extent any such losses, liabilities, damages, costs and expenses are incurred as a result of or in connection with any gross negligence, bad faith or willful misconduct on the part of the applicable AP Indemnified Party or the applicable Trust Indemnified Party, as the case may be. The term "affiliate" in this Section 10 shall include, with respect to any person, entity or organization, any other person, entity or organization which directly, or indirectly through one or more intermediaries, controls, is controlled by or is under common control with such person, entity or organization.

(d)

If the indemnification provided for in this Section 10 is unavailable to an AP Indemnified Party under Section 10(a) or a Trust Indemnified Party under Section 10(b) or insufficient to hold an indemnified party harmless in respect of any losses, liabilities, damages, costs and expenses referred to therein, then each applicable indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, liabilities, damages, costs and expenses (i) in such proportion as is appropriate to reflect the relative benefits received by the applicable MacroShares Trusts, on the one hand, and by the applicable Authorized Participants, on the other hand, from the services provided hereunder or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of each of the applicable MacroShares Trusts, on the one hand, and of each of the applicable Authorized Participants, on the other hand, in connection with, to the extent applicable, the statements or omissions which resulted in such losses, liabilities, damages, costs and expenses, as well as any other relevant equitable considerations. The relative benefit of a MacroShares Trust shall be deemed to be in the same proportion as the total net proceeds from the offering (after deducting expenses) received by that MacroShares Trust. To the extent applicable, the relative fault of a MacroShares Trust, on the one hand, and of the Authorized Participant, on the other hand, shall be determined by reference to, among other things, whether the untrue statement or alleged untrue statement of a material fact or omission or alleged omission relates to information supplied by that trust or by the Authorized Participant and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid or payable by a party as a result of the losses, liabilities, damages, costs and expenses referred to in this Section 10(d) shall be deemed to include any legal or other fees or expenses reasonably incurred by such party in connection with investigating, preparing to defend or defending any action, suit or proceeding (each, a "Proceeding") related to such losses, liabilities, damages, costs and expenses.

(e)

Each MacroShares Trust and each Authorized Participant agrees that it would not be just and equitable if contribution pursuant to this Section 10 were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in Section 10(d) above. No Authorized Participant shall be required to contribute any amount in excess of the amount by which the total price at which the applicable Paired MacroShares created by such Authorized Participant and distributed to the public exceeds the amount of any damage which such Authorized Participant has otherwise been required to pay by reason of such untrue statement or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

(f)

The indemnity and contribution provisions contained in this Section 10 shall remain in full force and effect regardless of any investigation made by or on behalf of an Authorized Participant, its partners, stockholders, members, directors, officers, employees and or any person (including each partner, stockholder, member, director, officer or employee of such person) who controls an Authorized Participant within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, or by or on behalf of each of the MacroShares Trusts, its managers, members, officers, employees or any person who controls the applicable Paired Trusts within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, and shall survive any termination of this Participants Agreement. Each MacroShares Trust and each Authorized Participant agree promptly to notify each other of the commencement of any Proceeding against it and, in the case of a MacroShares Trust, against the applicable Trustee or the applicable Depositor, in connection with the issuance and sale of the applicable Paired MacroShares or in connection with the applicable Registration Statement or the applicable Prospectus.

(g)

Each MacroShares Trust hereby agrees severally and not jointly to pay any Trust Indemnified Party such amounts when due under this Section 10 (including any amount in contribution thereof that may be owed to such Trust Indemnified Party pursuant to this Section 10), and to pay any and all expenses (including reasonable and documented counsel fees and expenses) incurred by the Trust Indemnified Party in enforcing its rights under this Section 10.

Section 11.

Limitation of Liability.

(a)

None of the Administrative Agent, any of the Depositors, any of the Trustees or any of the Authorized ParticipantS shall be liable to each other, if applicable, or to any other Person, including any AP Indemnified Party or any other person claiming by, through or on behalf of an Authorized Participant, for any losses, liabilities, damages, costs or expenses arising out of any mistake or error in data or other information provided to any of them by any of the others or any other person or out of any interruption or delay in the electronic means of communications used by them.

(b)

Tax Liability. Each Authorized Participant shall be responsible for the payment of any transfer tax, sales or use tax, stamp tax, recording tax, value added tax and any other similar tax or government charge applicable to the creation or redemption of any MacroShares Unit made pursuant to this Participants Agreement, regardless of whether or not such tax or charge is imposed directly on each Authorized Participant. To the extent the applicable Trustee, the Administrative Agent, the applicable Depositor or the applicable Paired Trusts are required by law to pay any such tax or charge, the applicable Authorized Participant agrees to promptly indemnify such party for any such payment, together with any applicable penalties, additions to tax or interest thereon.

Section 12.

In the event that an Authorized Participant wishes to act as an authorized participant of additional Paired Trusts it must execute an additional Schedule I with the applicable Depositor, applicable Trustee and the Administrative Agent and the date of such execution shall be the date this Agreement with respect to such additional Paired Trusts. This Agreement may be terminated with respect to all or part of the Paired Trusts to which an Authorized Participant serves as an authorized participant pursuant to Schedule I at any time by any party upon thirty (30) days' prior written notice to the other applicable parties unless earlier terminated: (i) in accordance with Section 2(a), with respect only to any Authorized Participant to whom such section applies, (ii) upon notice to the Authorized Participant by the applicable Trustee in the event of a breach by the Authorized Participant of this Participants Agreement or the applicable Procedures described or incorporated herein, (iii) immediately in the circumstances described in Section 20(j), or (iv) at such time as the applicable Paired Trusts are terminated in accordance with the terms of the applicable MacroShares Trust Agreements.

Notwithstanding the foregoing, each Authorized Participant may, without the written approval of the applicable AP Indemnified Party, prepare and circulate to one or more of its potential investors one or more "written communications" (as defined under Rule 405 under the Securities Act) containing no more than the following: information contemplated by Rule 134 under the Securities Act ("Rule 134 Information") which is consistent with the then-current applicable prospectuses and information included in the then-current applicable prospectuses (a "Participant Free Writing Prospectus," and together with Rule 134 Information, the "Participant Written Communication").

(c)

Each Authorized Participant severally represents, warrants, covenants and agrees with the applicable Trustee, the Administrative Agent and the applicable Depositor that:

(i)

each Participant Written Communication prepared by it will not, as of the date such Participant Written Communication was conveyed or delivered to any prospective purchaser of MacroShares, include any untrue statement of a material fact or omit any material fact necessary to make the statements contained therein, in light of the circumstances under which they were made, not misleading; provided, however, that no Authorized Participant makes such representation, warranty or agreement to the extent such misstatements or omissions were the result of any inaccurate information which was included in the Prospectuses or any written information furnished to the related Authorized Participant by the applicable Trustee, the Administrative Agent and the applicable Depositor expressly for use therein, which information was not corrected by information subsequently filed with the SEC or by such information subsequently delivered by the applicable Trustee, the Administrative Agent or the applicable Depositor to the related Authorized Participant prior to the time of use of such Participant Written Communication;

(ii)

each item of Rule 134 Information prepared by it shall contain a legend substantially in the form of and in compliance with Rule 134(b) or (d) of the Securities Act, as applicable, and shall otherwise conform to all of the requirements of Rule 134 under the Securities Act;

(iii)

each Participant Free Writing Prospectus prepared by it shall contain a legend substantially in the form of and in compliance with Rule 433(c)(2)(i) of the Securities Act, shall be filed with the Securities and Exchange Commission by the Authorized Participant in accordance with Rule 433(d) and shall otherwise conform to all of the requirements for "Free Writing Prospectus" (as defined under Rule 405 under the Securities Act) under the Securities Act; and

(iv)

each Participant Free Writing Prospectus prepared by it shall be delivered to the applicable Trustee, the Administrative Agent and the applicable Depositor no later than the time of first use and, unless otherwise agreed to by the applicable Trustee, the Administrative Agent and the applicable Depositor and the related Authorized Participant, such delivery shall occur no later than the close of business for the applicable MacroShares Trust (Eastern Time) on the date of first use; provided, however, if the date of first use is not a Business Day, such delivery shall occur no later than the close of business for the applicable MacroShares Trust (Eastern Time) on the first Business Day preceding such date of first use.

(d)

Each Authorized Participant severally represents and agrees (i) that it did not enter into any contract of sale for any MacroShare prior to the initial time of sale as determined by the applicable Depositor (the "Initial Time of Sale") and (ii) that it will, at any time that such Authorized Participant is acting as an "underwriter" (as defined in Section 2(a)(11) of the Securities Act) with respect to any type of MacroShare, deliver to each investor to whom the MacroShares are offered a copy of the then-current applicable Prospectuses as required under the Securities Act.

(e)

Each Authorized Participant hereby agrees that, for the term of this Participants Agreement, the applicable Depositor may deliver the then-current Prospectuses, and any supplements or amendments thereto or recirculation thereof, to such Authorized Participant in Portable Document Format ("PDF") via electronic mail in lieu of delivering the Prospectuses in paper form. Each Authorized Participant may revoke the foregoing agreement at any time by delivering written notice to the applicable Depositor and the Administrative Agent and, whether or not such agreement is in effect, each Authorized Participant may, at any time, request reasonable quantities of the applicable Prospectuses, and any supplements or amendments thereto or recirculation thereof, in paper form from the applicable Depositor. Each Authorized Participant acknowledges that it has the capability to access, view, save and print material provided to it in PDF and that it will incur no appreciable extra costs by receiving the applicable Prospectuses in PDF instead of in paper form.

(f)

For as long as this Participants Agreement is effective, each applicable Authorized Participant agrees to be identified as an authorized participant of the applicable Paired Trusts (i) in the section of the applicable Prospectuses included within the relevant Registration Statements entitled "Plan of Distribution" and in any other section as may be required by the SEC, (ii) in any SEC filing as may be required under the Securities Act or the Exchange Act and (iii) on any website relating to the applicable Paired Trusts.

Section 15.

Certain Covenants of the Depositor. The applicable Depositor covenants and agrees:

(a)

to advise each applicable Authorized Participant promptly of the happening of any event during the term of this Participants Agreement which could require the making of any change in the Prospectuses then being used so that such Prospectuses would not include an untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they are made, not misleading, and, during such time, to prepare and furnish, at the expense of the applicable Paired Trusts, to each Authorized Participant promptly such amendments or supplements to such Prospectuses as may be necessary to reflect any such change;

(b)

[reserved];

(c)

on behalf of each of the applicable Paired Trusts, to file a post-effective amendment to their respective Registration Statements no less frequently than once per calendar quarter on or about the same time that the applicable Depositor files a quarterly or annual report pursuant to Section 13 or 15(d) of the Exchange Act (including the information contained in such report), until such time as the applicable Paired Trusts' reports filed pursuant to Section 13 or 15(d) of the Exchange Act are incorporated by reference in the applicable Registration Statement.

Section 16.

Addition and Removal of Authorized Participants.

(a)

On any Business Day, (i) any Person who satisfies the requirements set forth in Section 2 of this Participants Agreement may notify the Administrative Agent and the applicable Depositor of its desire to be added to Schedule I of this Participants Agreement with respect to all or part of the Paired Trusts then issued; and (ii) any Authorized Participant may notify the Administrative Agent and the applicable Depositor of its desire to become an Authorized Participant of additional issued Paired Trusts. The Administrative Agent shall review such Person's request, and if such Person is acceptable to the applicable Depositors, the Administrative Agent shall prepare, or cause to be prepared, a supplement to this Participants Agreement under which, the Person to which clause (i) above is referred to will be added to Schedule I attached hereto and to the applicable Paired Trusts specified in such Schedule and shall assume the role, responsibilities and privileges of an Authorized Participant of the relevant Paired Trusts as set forth in this Participants Agreement, and the Person to which clause (ii) is referred to will be added as an Authorized Participant to additional Paired Trusts on Schedule I. Upon instruction from the applicable Depositors, each of the Administrative Agent and the applicable Trustees hereby acknowledges and agrees that it will execute and deliver such supplement to the extent permitted by law and upon such execution, such Person will be deemed to be an Authorized Participant of the applicable Paired Trusts. Furthermore, each Authorized Participant acknowledges and agrees that its execution and delivery of such supplement shall not be required to bind any existing or future Authorized Participant to the terms and conditions set forth herein. With regard to an application to become a wholly new Authorized Participant, the applicable Trustees shall use commercially reasonable efforts to submit on behalf of such Person an application to create an account at DTC pursuant to which it can effectuate creations and/or redemptions in accordance with the applicable Procedures. To the extent required under the Exchange Act, the applicable Depositors shall file, within four (4) Business Days of the execution of a supplement hereto, a Form 8-K disclosing such supplement.

(b)

An Authorized Participant may terminate its role as an Authorized Participant of all or part of the Paired Trusts in accordance with Section 13 hereof. The Administrative Agent shall prepare, or cause to be prepared, an amendment to Schedule I under which such Authorized Participant shall be removed from such schedule or only from serving as an Authorized Participant from specific Paired Trusts, as applicable. The Administrative Agent, the applicable Depositors, the applicable Trustees and such Authorized Participant shall execute such amendment upon its preparation and delivery. Each Authorized Participant acknowledges and agrees that the execution and delivery by it of such amendment is not required for the removal of an Authorized Participant from the Schedule. To the extent required under the Exchange Act, the applicable Depositors shall file, within four (4) Business Days of the execution of an amendment, a Form 8-K disclosing such removal.

Section 17.

Third Party Beneficiaries. Each AP Indemnified Party, to the extent it is not a party to this Participants Agreement, is a third-party beneficiary of this Participants Agreement (each, a "Third Party Beneficiary") and may proceed directly against each applicable Authorized Participant (including by bringing proceedings against each such Authorized Participant in its own name) to enforce any obligation of such Authorized Participant under this Participants Agreement which directly or indirectly benefits such Third Party Beneficiary.

Section 18.

Force Majeure. No party to this Participants Agreement shall incur any liability for any delay in performance, or for the non-performance, of any of its obligations under this Participants Agreement by reason of any cause beyond its reasonable control. This includes any act of God or war or terrorism, any breakdown, malfunction or failure of transmission in connection with or other unavailability of any wire, communication or computer facilities, any transport, port or airport disruption, industrial action, acts and regulations and rules of any governmental or supra-national bodies or authorities or regulatory or self-regulatory organization or failure of any such body, authority or organization for any reason, to perform its obligations.

Section 19.

Ambiguous Instructions. If any Creation or Redemption Order Form otherwise in good form contains order terms that differ from the information provided in the telephone call at the time of issuance of the applicable order number, the Administrative Agent will attempt to contact one of the Authorized Persons of the Authorized Participant to request confirmation of the terms of the Order. If an Authorized Person confirms the terms as they appear in the Order, then the Order will be accepted and processed. If an Authorized Person contradicts the Order terms, the Order will be deemed invalid, and a corrected Order must be received by the Administrative Agent, as the case may be, not later than within fifteen (15) minutes of such contact with the Authorized Person. If the Administrative Agent is not able to contact an Authorized Person, then the Order shall be accepted and processed in accordance with its terms notwithstanding any inconsistency from the terms of the telephone information. In the event that an Order contains terms that are illegible, the Order will be deemed invalid and the Administrative Agent will attempt to contact one of the Authorized Persons of the Authorized Participant to request retransmission of the Order. A corrected Order must be received by the Administrative Agent not later than within fifteen (15) minutes of such contact with the Authorized Person. The Administrative Agent will incur no liabilities under this Section 19.

Section 20.

Miscellaneous.

Amendment and Modification. This Participants Agreement, each set of Procedures attached hereto and the Exhibits attached hereto may be amended, modified or supplemented by the applicable Trustee, the Administrative Agent and the applicable Depositor, without consent of any holder of the applicable MacroShares or the applicable Authorized Participants; provided, however, that no amendment may be made which would (i) alter the status of any MacroShares Trust as a partnership for federal income tax purposes or (ii) cause any MacroShares Trust to be required to register as an investment company under the Investment Company Act of 1940, as amended, or (iii) cause or potentially cause the assets of any MacroShares Trust to constitute "plan assets" within the meaning of the Employee Retirement Income Security Act of 1974, as amended ("ERISA"). After the amendment, modification or supplement has been agreed to, the Administrative Agent shall mail a copy of such amendment, modification or supplement to each applicable Authorized Participant. The Administrative Agent may also deliver such amendment, modification or supplement thereto by electronic mail; provided, however, that physical delivery via the United States postal system or similar system shall be required. For the purposes of this Participants Agreement, mail will be deemed received by the recipient thereof on the third (3rd) calendar day following the deposit of such mail into the United States postal system or similar system. Within ten (10) calendar days after its deemed receipt, the amendment, modification or supplement will become part of this Participants Agreement, the Attachments or the Exhibits, as the case may be, in accordance with its terms.

(a)

Waiver of Compliance. Any failure of any of the parties to comply with any obligation, covenant, agreement or condition herein may be waived by the party entitled to the benefits thereof only by a written instrument signed by the party granting such waiver, but any such written waiver, or the failure to insist upon strict compliance with any obligation, covenant, agreement or condition herein, shall not operate as a waiver of, or estoppel with respect to, any subsequent or other failure.

(i)

Severance.

The Paired Shares constituting a MacroShares Unit shall only be issued in connection with the instructions set forth herein and in coordination with State Street Bank and Trust Company, not in its individual capacity but solely (i) as trustee (the "Up Trustee") of the MacroShares $100 Oil Up Trust (the "Up Trust") and (ii) as trustee (the "Down Trustee" and, in its various capacities under the applicable Trust Agreements, the "Trustee") of the MacroShares $100 Oil Down Trust (the "Down Trust" and, together with the Up Trust, the "Paired Trusts") and MacroMarkets LLC, not in its individual capacity but solely as administrative agent of the Paired Trusts (the "Administrative Agent").

Capitalized terms used but not defined herein shall have the meanings assigned to such terms in the Participants Agreement and if such defined term is not set forth therein, then such defined term shall have the meaning assigned to such term in either (i) the Amended and Restated MacroShares $100 Oil Up Trust Agreement, dated as of March [ ], 2008 (the "Up Trust Agreement"), among the Up Trustee, the Administrative Agent, MACRO Financial, LLC, as a marketing agent (the "Marketing Agent") and MACRO Securities Depositor, LLC (the "Depositor") or (ii) the Amended and Restated MacroShares $100 Oil Down Trust Agreement, dated as of March [ ], 2008 (the "Down Trust Agreement" and, together with the Up Trust Agreement, the "Trust Agreements"), among the Down Trustee, the Administrative Agent, the Marketing Agent and the Depositor.

The Paired Shares may be created solely by the parties listed on Schedule I attached to the Participants Agreement (each, an "Authorized Participant"). The Paired Shares may be created only in pairs of 50,000 Up MacroShares and 50,000 Down MacroShares (each such pair, a "MacroShares Unit").

The Paired Shares will be created on a net basis daily with respect to all Orders received from all Authorized Participants on such date. In the event that the number of MacroShares Units to be created based on the Creation Orders on such date exceeds the number of MacroShares Units to be redeemed pursuant to the Redemption Orders on such date, the newly created MacroShares Units that will be issued will be equal to the total number of MacroShares Units created minus the total number of MacroShares Units redeemed. Similarly, in the event that the number of MacroShares Units to be redeemed pursuant to the Redemption Orders on such date exceeds the number of MacroShares Units to be created based on the Creation Orders on such date, the actual number of MacroShares Units to be issued will be zero. The Settlement Contracts created on each date, if any, any adjustment to amounts allocated under the Income Distribution Agreement and the purchase of new Eligible Treasuries, if any, will also be done on a net basis daily, in accordance to the daily netting of creation and redemption of MacroShares Units (such netting, collectively, the "Net Daily Basis").

Attachment A-1

Upon acceptance of the Participants Agreement by the Authorized Participant, the Administrative Agent will assign a personal identification number (a "PIN number") to each Authorized Person authorized to act on behalf of an Authorized Participant. This will allow an Authorized Participant through its Authorized Person(s) to place Creation Order(s) or Redemption Order(s) for MacroShares.

Important Notes:

Any Order is subject to rejection by the Depositor and the Administrative Agent for the reasons set forth in the Trust Agreements or the Participants Agreement.

All Orders are subject to the provisions of the Trust Agreements and the Participants Agreement relating to unclear or ambiguous instructions.

Attachment A-2

CREATION PROCESS

On any Price Determination Day, an Authorized Participant may submit a Creation Order, substantially in the form of EXHIBIT B to the Participants Agreement (or to the extent that such order is electronic, such order shall include the information set forth on such exhibit), to the Administrative Agent by the Order Cut-Off Time (as defined below) on such day (such Price Determination Day, "T," and any number added to T shall refer to such order day plus the number of Price Determination Days following such day) to create one or more MacroShares Units. Any Creation Order that is placed after the Order Cut-off Time shall be void and may be resubmitted on the next Price Determination Day based on the Underlying Value as of the calendar day preceding such next Price Determination Day.

In connection with the Creation Order, the Authorized Participant shall have wired to the Trustee by 10:00 a.m. New York City time on T+1 or, in the event that T is a Distribution Date or the Business Day following the Distribution Date (such date, "an X or an X+1 Date") on T+3, the following:

a Transaction Fee for the MacroShares Units being created;

cash equal to the aggregate Underlying Value of the Up MacroShares being created, measured on the last calendar day preceding T;

cash equal to the aggregate Underlying Value of the Down MacroShares being created, as measured on the last calendar day preceding T (such deposits for each MacroShares Unit, the "MacroShares Unit Deposit");

in the event that the Issuance Order Date is an X or an X+1 Date, the Authorized Participant submitting such order will be required to deposit, in addition to the MacroShares Unit Deposit, a sum equal to the Up and Down Earned Income Accruals for the intervening days between the Issuance Order Date and the Issuance Date (each calculated on the basis of the Applicable Reference Price of Crude Oil on the Issuance Order Date) (such sum, the "MacroShares Unit Deposit Addition");and

for any Creation Order submitted prior to September 30th, 2008, a fee equal to [1.00]% of the aggregate par amount of Paired MacroShares being created (such fee, the "Early Creation Fee").

Upon the satisfaction of the conditions set forth above, the Administrative Agent shall instruct the Trustee to allocate from the applicable Netting Account available MacroShares and, in the event that there are insufficient such shares in the applicable Netting Account, instruct the Trustees to cause the Paired Trusts to issue Paired Shares and deliver such shares to the creating Authorized Participants' accounts at the Depository Trust Company ("DTC") to satisfy all the Creation Orders submitted, not later than 3:00 p.m. New York City time on T+1 (or on T+3 if T is an X or an X+1 Date). The Trustee, upon written instruction from the Administrative Agent, shall adjust, on a Net Daily Basis, the amount to be allocated under the Income Distribution Agreement on the next Distribution Date and enter, if applicable, into additional Settlement Contracts associated with the MacroShares Units being created.

II. REDEMPTION OF PAIRED MACROSHARES

Scope of Procedures and Overview

These procedures (the "Redemption Procedures") describe the processes by which an Authorized Participant may redeem Paired MacroShares constituting one or more MacroShares Units. The Paired MacroShares constituting a MacroShares Unit shall only be redeemed in accordance with the Redemption Procedures set forth herein and in coordination with the Trustee and the Administrative Agent.

The MacroShares may be redeemed solely in accordance with the instructions of the Authorized Participants. The Authorized Participants shall submit Paired Shares which constitute one or more MacroShares Units for redemption. The MacroShares will be redeemed for cash from the applicable Netting Account or, in the event that the applicable Netting Account does not have sufficient cash, for cash and/or Eligible Treasuries pursuant to the applicable Trust Agreement.

The MacroShares will be redeemed on a net basis daily with respect to all Orders received from all Authorized Participants on such date. In the event that the number of MacroShares Units to be redeemed based on the Redemption Orders on such date exceeds the number of MacroShares Units to be created pursuant to the Creation Orders on such date, the MacroShares Units that will be redeemed will be equal to the total number of MacroShares Units redeemed minus the total number of MacroShares Units created. Similarly, in the event that the number of MacroShares Units to be created based on the Creation Orders on such date exceeds the number of MacroShares Units to be redeemed pursuant to the Redemption Orders on such date, the actual number of MacroShares Units that will be redeemed will equal zero. The Settlement Contracts settled on each date, if any, and any adjustment to amounts allocated under the Income Distribution Agreement, will also be done on a net basis daily, in accordance to the daily netting of creation and redemption of MacroShares Units (such netting, collectively, the "Net Daily Basis").
