FORM OF JEFFERIES COMMODITY REAL RETURN ETF PARTICIPANT AGREEMENT

Exhibit 4.2

FORM OF

This Participant Agreement (the “Agreement”), dated as of 2010, is entered into by and among (the “Authorized Participant”), Jefferies Commodity Real Return ETF, a Delaware statutory trust (the “Trust”), and Jefferies Commodity Investment Services, LLC, a Delaware limited liability company, as managing owner of the Trust (the “Managing Owner”).

SUMMARY

As provided in the Amended and Restated Declaration of Trust and Trust Agreement of the Trust (the “Trust Agreement”) as currently in effect and described in the Prospectus (defined below), units of fractional undivided beneficial interest in and ownership of the Trust (the “Shares”) may be created or redeemed by the Managing Owner for an Authorized Participant in aggregations of ten thousand (50,000) Shares (each aggregation, a “Basket”). Baskets are offered only pursuant to the registration statement of the Trust on Form S-1, as amended (Registration No.: 333-164811), as declared effective by the Securities and Exchange Commission (“SEC”) and as the same may be amended from time to time thereafter or any successor registration statement in respect of Shares of the Trust (collectively, the “Registration Statement”) together with the prospectus of the Trust in the form filed with the SEC under Rule 424(b) under the Securities Act of 1933, as amended (the “1933 Act”), after the effectiveness of the Registration Statement (the “Prospectus”), and as supplemented from time to time. Under the Trust Agreement, the Managing Owner is authorized to issue Baskets to, and redeem Baskets from, Authorized Participants, only through the facilities of The Depository Trust Company (“DTC” or the “Depository”), or a successor depository, and only in exchange for cash. This Agreement sets forth the specific procedures by which an Authorized Participant may create or redeem Baskets.

Capitalized terms used but not otherwise defined in this Agreement shall have the meanings assigned to such terms in the Trust Agreement. To the extent there is a conflict between any provision of this Agreement and the provisions of the Trust Agreement, the provisions of the Trust Agreement shall control. To the extent there is a conflict between any provision of this Agreement and the provisions of the Prospectus, the Prospectus shall control.

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:

Section 1. Order Placement. To place orders for the Managing Owner to create or redeem one or more Baskets, Authorized Participants must follow the procedures for creation and redemption referred to in Section 3 of this Agreement and the procedures described in Attachment A hereto (the “Procedures”), as each may be amended, modified or supplemented from time to time.

Section 2. Status of Authorized Participant. The Authorized Participant represents and warrants and covenants the following:

(a) The Authorized Participant is a participant of DTC (as such a participant, a “DTC Participant”). If the Authorized Participant ceases to be a DTC Participant, the Authorized Participant shall give immediate notice to the Managing Owner of such event, and this Agreement shall terminate immediately as of the date the Authorized Participant ceased to be a DTC Participant.

(b) Unless Section 2(d) applies, the Authorized Participant either (i) is registered as a broker-dealer under the Securities Exchange Act of 1934, as amended (the “1934 Act”), and is a member in good standing of the Financial Industry Regulatory Authority (“FINRA”), or (ii) is exempt from being, or otherwise is not required to be, licensed as a broker-dealer or a member of FINRA, and in either case is qualified to act as a broker or dealer in the states or other jurisdictions where the nature of its business so requires. The Authorized Participant shall maintain any such registrations, qualifications and membership in good standing and in full force and effect throughout the term of this Agreement. The Authorized Participant shall comply with all applicable United States federal laws, including without limitation, the delivery requirements of Section 5 of the 1933 Act and all applicable rules of the SEC, the laws of the states or other jurisdictions concerned, and the rules and regulations promulgated thereunder, and with the Constitution, By-Laws and Conduct Rules of FINRA, if it is a FINRA member, and shall not offer or sell Shares in any state or jurisdiction where they may not lawfully be offered and/or sold.

(c) The Authorized Participant understands and acknowledges that the proposed method by which Baskets will be created and traded may raise certain issues under applicable securities laws. The Authorized Participant understands and acknowledges that, for example, because new Shares can be created and issued on an ongoing basis, at any point during the life of the Trust, a “distribution,” as such term is used in the 1933 Act, may be occurring. The Authorized Participant is cautioned that some of its activities may result in its being deemed a participant in a distribution in a manner that would render it a statutory underwriter and subject it to the prospectus delivery and liability provisions of the 1933 Act. The Authorized Participant should review the “Plan of Distribution” section of the Prospectus and consult with its own counsel in connection with entering into this Agreement and submitting a Purchase Order Subscription Agreement (defined below).

(d) If the Authorized Participant is offering or selling Shares in jurisdictions outside the several states, territories and possessions of the United States and is not otherwise required to be registered, qualified or a member of FINRA as set forth in Section 2(b) above, the Authorized Participant shall (i) observe the applicable laws of the jurisdiction in which such offer and/or sale is made, (ii) comply with the full disclosure requirements of the 1933 Act, and the regulations promulgated thereunder, and (iii) conduct its business in accordance with the spirit of the FINRA Conduct Rules.

(e) The Authorized Participant is in compliance with the money laundering and related provisions of the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (the “USA PATRIOT Act”), and the regulations promulgated thereunder, if the Authorized Participant is subject to the requirements of the USA PATRIOT Act.

Section 3. Orders. (a) All orders to create or redeem Baskets shall be made in accordance with the terms of the Trust Agreement, this Agreement and the Procedures. Each party shall comply with such foregoing terms and procedures to the extent applicable to it. The Authorized Participant hereby consents to the use of recorded telephone lines whether or not such use is reflected in the Procedures. The Managing Owner may issue additional or other procedures from time to time relating to the manner of creating or redeeming Baskets which are not related to the Procedures, and the Authorized Participant shall comply with such procedures of which it has been notified in accordance with this Agreement.

(b) The Authorized Participant acknowledges and agrees on behalf of itself and any party for which it is acting (whether such party is a customer or otherwise) that each order to create a Basket (a “Purchase Order Subscription Agreement”) and each order to redeem a Basket (a “Redemption Order”, and each Purchase Order Subscription Agreement and Redemption Order, an “Order”) may not be revoked by the Authorized Participant upon its delivery to the Managing Owner. A form of Purchase Order Subscription Agreement is attached hereto as Exhibit B and a form of Redemption Order is attached hereto as Exhibit C.

(c) The Managing Owner shall have the absolute right, but shall have no obligation, to reject any Purchase Order Subscription Agreement or Creation Basket Capital Contribution (i) determined by the Managing Owner not to be in proper form; (ii) that the Managing Owner has determined would have adverse tax consequences to the Trust or to the Beneficial Owners; (iii) the acceptance or receipt of which could, in the opinion of counsel to the Managing Owner, be unlawful; or (iv) if circumstances outside the control of the Managing Owner make it, for all practical purposes, not feasible to process Creation Baskets. The Managing Owner shall not be liable to any person by reason of the rejection of any Purchase Order Subscription Agreement or Creation Basket Capital Contribution.

(d) The Managing Owner shall reject any Redemption Order the fulfillment of which its counsel advises would be illegal under applicable laws and regulations, and the Managing Owner shall have no liability to any person for rejecting a Redemption Order in such circumstances.

(e) The Managing Owner may, in its discretion, suspend the right of redemption, or postpone the applicable Redemption Settlement Time, (i) for any period during which the NYSE Arca, Inc. or any exchange on which the Trust’s assets are regularly traded is closed other than for customary weekend or holiday closings, or trading is suspended or restricted; (ii) for any period during which an emergency exists as a result of which delivery, disposal or evaluation of the Trust’s assets is not reasonably practicable; or (iii) for such other period as the Managing Owner determines to be necessary for the protection of the Beneficial Owners. The Managing Owner is not liable to any person or in any way for any loss or damages that may result from any such suspension or postponement.

Section 4. Fees. In connection with each Order by an Authorized Participant to create or redeem one or more Baskets, the Managing Owner shall charge, and the Authorized Participant shall pay from its DTC account to the Managing Owner, the Transaction Fee prescribed in the Trust Agreement and/or the Prospectus (as applicable) with respect to such creation or redemption. The initial Transaction Fee shall be [ ] Dollars ($[-]) per Basket.

The Transaction Fee may be adjusted from time to time as set forth in the Trust Agreement and/or the Prospectus (as applicable). As described in the Procedures, the Authorized Participant will be charged by the Managing Owner an additional processing charge if the Authorized Participant fails timely to deliver the Creation Basket Capital Contribution (in the case of a Purchase Order Subscription Agreement) or the Baskets (in the case of a Redemption Order).

Section 5. Authorized Persons. Concurrently with the execution of this Agreement and from time to time thereafter, the Authorized Participant shall deliver to the Managing Owner, notarized and duly certified as appropriate by its secretary or other duly authorized person, a certificate in the form of Exhibit A setting forth the names and signatures of all persons authorized to give instructions relating to activity contemplated hereby or by any other notice, request or instruction given on behalf of the Authorized Participant (each, an “Authorized Person”). The Managing Owner may accept and rely upon such certificate as conclusive evidence of the facts set forth therein and shall consider such certificate to be in full force and effect until the Managing Owner receives a superseding certificate bearing a subsequent date. Upon the termination or revocation of authority of any Authorized Person by the Authorized Participant, the Authorized Participant shall give immediate written notice of such fact to the Managing Owner and such notice shall be effective upon receipt by the Managing Owner. The Managing Owner shall issue to each Authorized Person a unique personal identification number (the “PIN Number”) by which such Authorized Person shall be identified and by which instructions issued by the Authorized Participant hereunder shall be authenticated. The PIN Number shall be kept confidential by the Authorized Participant and shall only be provided to the Authorized Person. If, after issuance, the Authorized Person’s PIN Number is changed, the new PIN Number shall become effective on a date mutually agreed upon by the Authorized Participant and the Managing Owner.

Section 6. Redemption. The Authorized Participant represents and warrants that it will not obtain an Order Number (as described in the Procedures) from the Managing Owner for the purpose of redeeming a Basket unless it first ascertains that (i) it or its customer, as the case may be, owns outright or has full legal authority and legal and beneficial right to tender for redemption the Baskets to be redeemed and to receive the entire proceeds of the redemption, and (ii) such Baskets have not been loaned or pledged to another party and are not the subject of a repurchase agreement, securities lending agreement or any other arrangement which would preclude the delivery of such Baskets to the Managing Owner on the Business Day following the Redemption Order Date.

Section 7. Role of Authorized Participant. (a) The Authorized Participant acknowledges that, for all purposes of this Agreement and the Trust Agreement, the Authorized Participant shall be deemed to be an independent contractor and shall have no authority to act as agent for the Trust or the Managing Owner in any matter or in any respect.

(b) The Authorized Participant will make itself and its employees available, upon request, during normal business hours to consult with the Managing Owner or its designees concerning the performance of the Authorized Participant’s responsibilities under this Agreement.

(c) With respect to any creation or redemption transaction made by the Authorized Participant pursuant to this Agreement for the benefit of any customer or any other DTC Participant or Indirect Participant, or any other Beneficial Owner, the Authorized Participant shall extend to any such party all of the rights, and shall be bound by all of the obligations, of a DTC Participant in addition to any obligations that it undertakes hereunder or in accordance with the Trust Agreement.

(d) Upon reasonable request by the Managing Owner, the Authorized Participant will, subject to any limitations arising under federal or state securities laws relating to privacy or other obligations it may have to its customers, provide the Managing Owner written notice indicating the number of Shares that the Authorized Participant may hold as record holder and the number of such Shares that it holds for the benefit of other broker-dealers that clear and settle transactions in Shares through the Authorized Participant, in each case as of the date of such request, with respect to the Trust. In addition, the Authorized Participant agrees, upon request of the Managing Owner, and subject to applicable laws, rules and regulations, to transmit to its account holders who are Beneficial Owners of Shares, such written materials received from the Managing Owner (including notices, annual reports, disclosure or other informational or tax materials and any amendments or supplements thereto and other communications) as may be required to be transmitted to Beneficial Owners pursuant to the Trust Agreement or applicable law, provided that the expenses associated with such transmissions shall be borne by the Managing Owner in accordance with usual custom and practice in respect of such communications.

Section 8. Indemnification.

(a) The Authorized Participant hereby indemnifies and holds harmless the Trust and the Managing Owner, their respective direct or indirect affiliates (as defined below) and their respective directors, trustees, managing owners, partners, members, managers, officers, employees and agents (each, an “AP Indemnified Party”) from and against any losses, liabilities, damages, costs and expenses (including attorneys’ fees and the reasonable costs of investigation) incurred by such AP Indemnified Party as a result of or in connection with: (i) any breach by the Authorized Participant of any provisions of this Agreement, including its representations, warranties and covenants; (ii) any failure on the part of the Authorized Participant to perform any of its obligations set forth in this Agreement; (iii) any failure by the Authorized Participant to comply with applicable laws and the rules and regulations of self-regulatory organizations; (iv) any actions of such AP Indemnified Party in reliance upon any instructions issued in accordance with the Procedures believed by the AP Indemnified Party to be genuine and to have been given by the Authorized Participant; or (v) (A) any representation by the Authorized Participant, its employees or its agents or other representatives about the Shares, any AP Indemnified Party or the Trust that is not consistent with the Trust’s then-current Prospectus made in connection with the offer or the solicitation of an offer to buy or sell Shares and (B) any untrue statement or alleged untrue statement of a material fact contained in any research reports, marketing material and sales literature described in Section 12(b) hereof or any alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading to the extent that such statement or omission relates to the Shares, any AP Indemnified Party or the Trust, unless, in either case, such representation, statement or omission was made or included by the Authorized Participant at the written direction of the Managing

Owner or is based upon any omission or alleged omission by the Managing Owner to state a material fact in connection with such representation, statement or omission necessary to make such representation, statement or omission not misleading.

(b) The Managing Owner hereby agrees to indemnify and hold harmless the Authorized Participant, 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 1933 Act (each, a “Managing Owner Indemnified Party”) from and against any losses, liabilities, damages, costs and expenses (including attorneys’ fees and the reasonable cost of investigation) incurred by such Managing Owner Indemnified Party as a result of (i) any breach by the Managing Owner of any provision of this Agreement that relates to the Managing Owner; (ii) any failure on the part of the Managing Owner to perform any obligation of the Managing Owner set forth in this Agreement; (iii) any failure by the Managing Owner to comply with applicable laws; or (iv) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement as originally declared effective by the SEC or in any amendment thereof, or in any Prospectus, 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 the Registration Statement or the Prospectus based on information furnished in writing by or on behalf of the Authorized Participant expressly for use in the Registration Statement or the Prospectus.

(c) This Section 8 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 AP Indemnified Party or the Managing Owner Indemnified Party, as the case may be. The term “affiliate” in this Section 8 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) The indemnity agreements contained in this Section 8 shall remain in full force and effect regardless of any investigation made by or on behalf of the Authorized Participant, its partners, stockholders, members, directors, officers, employees or any person (including each partner, stockholder, member, director, officer or employee of such person) who controls the Authorized Participant within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, or by or on behalf of the Managing Owner, its partners, stockholders, members, managers, directors, officers, employees or any person who controls the Managing Owner within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, and shall survive any termination of this Agreement. The Managing Owner, for itself and on behalf of the Trust, and the Authorized Participant agree promptly to notify each other of the commencement of any Proceeding against it and, in the case of the Managing Owner, against any of the Managing Owner’s officers or directors, in connection with the issuance and sale of the Shares or in connection with the Registration Statement or the Prospectus.

Section 9. (a) Limitation of Liability. In the absence of gross negligence, bad faith or willful misconduct, neither the Managing Owner, whether acting on its own behalf or on behalf of the Trust, nor the Authorized Participant shall be liable to each other or to any other person,

including any party claiming by, through or on behalf of the 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 each other or any other person or out of any interruption or delay in the electronic means of communications used by them.

(b) Tax Liability. The 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 Basket made pursuant to this Agreement, regardless of whether or not such tax or charge is imposed directly on the Authorized Participant. To the extent the Managing Owner or the Trust is required by law to pay any such tax or charge, the Authorized Participant agrees to promptly indemnify such party for any such payment, together with any applicable penalties, additions to tax or interest thereon.

Section 10. Acknowledgment. The Authorized Participant acknowledges receipt of a (i) copy of the Trust Agreement and (ii) the current Prospectus of the Trust and represents that it has reviewed and understands such documents.

Section 11. Effectiveness and Termination. Upon the execution of this Agreement by the parties hereto, this Agreement shall become effective in this form as of the date first set forth above, and may be terminated at any time by any party upon thirty (30) days prior written notice to the other parties unless earlier terminated: (i) in accordance with Section 2(a) hereof; (ii) upon notice to the Authorized Participant by the Managing Owner in the event of a breach by the Authorized Participant of this Agreement or the procedures described or incorporated herein; (iii) immediately in the circumstances described in Section 17(j) hereof; or (iv) at such time as the Trust is terminated pursuant to the Trust Agreement.

Section 12. Marketing Materials; Representations Regarding Shares; Identification in Registration Statement.

(a) The Authorized Participant represents, warrants and covenants that (i), without the written consent of the Managing Owner, the Authorized Participant shall not make, or permit any of its representatives to make, any representations concerning the Shares or any AP Indemnified Party other than representations contained (A) in the then-current Prospectus of the Trust, (B) in printed information approved by the Managing Owner as information supplemental to such Prospectus or (C) in any promotional materials or sales literature furnished to the Authorized Participant by the Managing Owner, and (ii) the Authorized Participant shall not furnish or cause to be furnished to any person or display or publish any information or material relating to the Shares, any AP Indemnified Person or the Trust that are not consistent with the Trust’s then current Prospectus. Copies of the then current Prospectus of the Trust and any such printed supplemental information will be supplied by the Managing Owner to the Authorized Participant in reasonable quantities upon request.

(b) Notwithstanding the foregoing, the Authorized Participant may without the written approval of the Managing Owner prepare and circulate in the regular course of its business research reports, marketing material and sales literature that includes information, opinions or recommendations relating to the Shares (i) for public dissemination, provided that such research reports, marketing material or sales literature compare the relative merits and

benefits of Shares with other products; and (ii) for internal use by the Authorized Participant. The Authorized Participant shall file all such research reports, marketing material and sales literature related to the Shares with FINRA to the extent required by the FINRA Conduct Rules.

(c) The Authorized Participant hereby agrees that for the term of this Agreement the Managing Owner may deliver the then-current Prospectus, and any supplements or amendments thereto or recirculation thereof, to the Authorized Participant in Portable Document Format (“PDF”) via electronic mail in lieu of delivering the Prospectus in paper form. The 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 Prospectus in PDF instead of in paper form. The Managing Owner shall, when requested by the Authorized Participant, make available at no cost the software and technical assistance necessary to allow the Authorized Participant to access, view and print the PDF version of the Prospectus.

(d) For as long as this Agreement is effective, the Authorized Participant agrees to be identified as an authorized participant of the Trust (i) in the section of the Prospectus entitled “Creation and Redemption of Shares” and in any other section as may be required by the SEC and (ii) on the Trust’s website. Upon the termination of this Agreement, (i) the Managing Owner shall remove such identification from the Prospectus in the amendment of either the Registration Statement or a supplement to the Prospectus, as applicable, next occurring after the date of the termination of this Agreement and (ii) the Managing Owner shall promptly update the Trust’s website to remove any identification of the Authorized Participant as an authorized participant of the Trust.

Section 13. Certain Representations, Warranties and Covenants of the Managing Owner. The Managing Owner, on its own behalf and as sponsor of the Trust, covenants and agrees:

(a) that (i) the Registration Statement and the Prospectus contained therein conform in all material respects to the requirements of the 1933 Act and the rules and regulations of the SEC thereunder and do not and will not, as of the applicable effective date as to the Registration Statement and any amendment thereto and as of the applicable filing date as to the Prospectus and any amendment or supplement thereto, contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, (ii) the sale and distribution of the Shares as contemplated herein will not conflict with or result in a breach or violation of any statute or any order, rule or regulation of any court or governmental agency or body having jurisdiction over the Trust, and (iii) no consent, approval, authorization, order, registration or qualification of or with any such court or governmental agency is required for the issuance of the Shares, except registration of the Shares under the 0000 Xxx.

(b) to notify the Authorized Participant promptly of the happening of any event during the term of this Agreement which could require the making of any change in the Prospectus then being used so that the Prospectus would not include an untrue statement of 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 Trust, to the Authorized Participant promptly such amendments or supplements to such Prospectus as may be necessary to reflect any such change;

(c) to deliver to the Authorized Participant, at each time (i) the Registration Statement or the Prospectus is amended or supplemented by the filing of a post-effective amendment and (ii) a new Registration Statement is filed to register additional Shares and a single Prospectus is used in reliance on Rule 429 under the 1933 Act, an Officer’s Certificate by duly authorized officers of the Managing Owner in the form attached hereto as Exhibit D.

In addition, any certificate signed by any officer of the Managing Owner and delivered to the Authorized Participant or counsel for the Authorized Participant pursuant hereto shall be deemed to be a representation and warranty by the Managing Owner to the Authorized Participant as to matters covered thereby.

Section 14. Third Party Beneficiaries. Each AP Indemnified Party, to the extent it is not a party to this Agreement, is a third-party beneficiary of this Agreement (each, a “Third Party Beneficiary”) and may proceed directly against the Authorized Participant (including by bringing proceedings against the Authorized Participant in its own name) to enforce any obligation of the Authorized Participant under this Agreement which directly or indirectly benefits such Third Party Beneficiary.

Section 15. Force Majeure. No party to this Agreement shall incur any liability for any delay in performance, or for the non-performance, of any of its obligations under this 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 16. Ambiguous Instructions. If a Purchase Order Subscription Agreement or a Redemption Order 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 Managing Owner 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 shall be accepted and processed. If an Authorized Person contradicts the Order terms, the Order shall be deemed invalid, and a corrected Order must be received by the Managing Owner, as the case may be, not later than the earlier of: (i) within 15 minutes of such contact with the Authorized Person; or (ii) 45 minutes after the Order Cut-Off Time. If the Managing Owner is not able to contact an Authorized Person, then the Order shall be accepted and processed in accordance with its terms notwithstanding any inconsistency with the terms of the telephone information. In the event that an Order contains terms that are illegible, the Order shall be deemed invalid and the Managing Owner 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 Managing Owner not later than the earlier of (i) within 15 minutes of such contact with the Authorized Person or (ii) 45 minutes after the Order Cut-Off Time, as the case may be.

Section 17. Miscellaneous.

(a) Amendment and Modification. This Agreement, the Procedures attached as Attachment A and the Exhibits hereto may be amended, modified or supplemented by the Trust and the Managing Owner, without consent of any Beneficial Owner or Authorized Participant from time to time by the following procedure. After the proposed amendment, modification or supplement has been agreed to, the Managing Owner shall mail a copy of the proposed amendment, modification or supplement to the Authorized Participant. For the purposes of this Agreement, mail shall be deemed received by the recipient thereof on the third (3^rd) day following the deposit of such mail into the United States postal system. Within ten (10) calendar days after its deemed receipt, the amendment, modification or supplement will become part of this Agreement, the Attachments or the Exhibits, as the case may be, in accordance with its terms. If at any time there is any material amendment, modification or supplement of any Participant Agreement (other than this Agreement), the Managing Owner shall promptly mail a copy of such amendment, modification or supplement to the Authorized Participant.

(b) 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.

(c) Notices. Except as otherwise specifically provided in this Agreement, all notices required or permitted to be given pursuant to this Agreement shall be given in writing and delivered by personal delivery, by postage prepaid registered or certified United States first class mail, return receipt requested, by nationally recognized overnight courier (delivery confirmation received) or by telex, telegram or telephonic facsimile or similar means of same day delivery (transmission confirmation received), with a confirming copy by regular mail, postage prepaid. For avoidance of doubt, notices may not be given or transmitted by electronic mail. Unless otherwise notified in writing, all notices to the Trust shall be given or sent to the Managing Owner. All notices shall be directed to the address or telephone or facsimile numbers indicated below the signature line of the parties on the signature page hereof.

(d) Successors and Assigns. This Agreement and all of the provisions hereof shall be binding upon and inure to the benefit of the parties and their respective successors and permitted assigns.

(e) Assignment. Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned by any party without the prior written consent of the other parties, except that any entity into which a party hereto may be merged or converted or with which it may be consolidated or any entity resulting from any merger, conversion, or consolidation to which such party hereunder shall be a party, or any entity succeeding to all or substantially all of the business of the party, shall be the successor of the party under this Agreement and except that the Managing Owner may delegate its obligations hereunder to the [Distributor or the

Administrator]¹ by notice to the Authorized Participant. The party resulting from any such merger, conversion, consolidation or succession shall notify the other parties hereto of the change. Any purported assignment in violation of the provisions hereof shall be null and void. Notwithstanding the foregoing, this Agreement shall be automatically assigned to any successor trustee or Managing Owner at such time such successor qualifies as a successor trustee or Managing Owner under the terms of the Trust Agreement.

(f) Governing Law; Consent to Jurisdiction. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware (regardless of the laws that might otherwise govern under applicable Delaware conflict of laws principles) as to all matters, including matters of validity, construction, effect, performance and remedies. Each party hereto irrevocably consents to the jurisdiction of the courts of the State of New York and of any federal court located in the Borough of Manhattan in such State in connection with any action, suit or other proceeding arising out of or relating to this Agreement or any action taken or omitted hereunder, and waives any claim of forum non conveniens and any objections as to laying of venue. Each party further waives personal service of any summons, complaint or other process and agrees that service thereof may be made by certified or registered mail directed to such party at such party’s address for purposes of notices hereunder.

(g) Counterparts. This Agreement may be executed in one or more counterparts, each of which shall be deemed to be an original copy of this Agreement and all of which, when taken together, shall be deemed to constitute one and the same agreement, and it shall not be necessary in making proof of this Agreement as to any party hereto to produce or account for more than one such counterpart executed and delivered by such party.

(h) Interpretation. The section headings contained in this Agreement are solely for the purpose of reference, are not part of the agreement of the parties and shall not in any way affect the meaning or interpretation of this Agreement.

(i) Entire Agreement. This Agreement and the Trust Agreement, along with any other agreement or instrument delivered pursuant to this Agreement and the Trust Agreement, supersede all prior agreements and understandings between the parties with respect to the subject matter hereof, provided, however, that the Authorized Participant shall not be deemed by this provision to be a party to the Trust Agreement.

(j) Severance. If any provision of this Agreement is held by any court or any act, regulation, rule or decision of any other governmental or supra-national body or authority or regulatory or self-regulatory organization to be invalid, illegal or unenforceable for any reason, it shall be invalid, illegal or unenforceable only to the extent so held and shall not affect the validity, legality or enforceability of the other provisions of this Agreement and this Agreement shall be construed as if such invalid, illegal, or unenforceable provision had never been contained herein, unless the Managing Owner determines in its discretion that the provision of this Agreement that was held invalid, illegal or unenforceable does affect the validity, legality or enforceability of one or more other provisions of this Agreement, and that this Agreement should not be continued without the provision that was held invalid, illegal or unenforceable, and in that

case, upon the Managing Owner’s notification of the trustee of such a determination, this Agreement shall immediately terminate and the Managing Owner shall so notify the Authorized Participant immediately.

(k) No Strict Construction. The language used in this Agreement shall be deemed to be the language chosen by the parties to express their mutual intent, and no rule of strict construction shall be applied against any party.

(l) Survival. Sections 8 (Indemnification) and 14 (Third Party Beneficiaries) hereof shall survive the termination of this Agreement.

(m) Other Usages. The following usages shall apply in interpreting this Agreement: (i) references to a governmental or quasi-governmental agency, authority or instrumentality shall also refer to a regulatory body that succeeds to the functions of such agency, authority or instrumentality; and (ii) “including” means “including, but not limited to.”

JEFFERIES COMMODITY REAL RETURN ETF PROCEDURES

CREATION AND REDEMPTION OF

JEFFERIES COMMODITY REAL RETURN ETF SHARES

Scope of Procedures and Overview

These procedures (the “Procedures”) describe the processes by which one or more Baskets of Jefferies Commodity Real Return ETF shares (the “Shares”) issuable by Jefferies Commodity Real Return ETF (the “Trust”) may be purchased or, once Shares have been issued, redeemed by an Authorized Participant (a “Participant”). Shares may be created or redeemed only in blocks of 50,000 Shares (each such block, a “Basket”).

Capitalized terms used in these Procedures without further definition have the meanings assigned to them in the Amended and Restated Declaration of Trust and Trust Agreement of the Trust (the “Trust Agreement”), dated as of [ ], 2010, and as amended from time-to-time, between Wilmington Trust company, a Delaware banking corporation, as trustee of the Trust (the “Trustee”) Jefferies Commodity Investment Services, LLC, as managing owner (the “Managing Owner”) and the Unitholders party thereto from time to time or the Participant Agreement entered into by each Participant with the Trust and the Managing Owner.

For purposes of these Procedures, a “Business Day” means a day other than Saturday, Sunday or other day when banks and/or securities exchanges in the City of New York are authorized or obligated by law or executive order to close.

“Order Cut-Off Time” means noon, Eastern Time, on each Business Day.

Baskets are issued pursuant to the Prospectus, which will be delivered by the Managing Owner to each Participant after its execution of the Participant Agreement, and are issued and redeemed in accordance with the Trust Agreement and the Participant Agreement. Baskets may be issued and redeemed on any Business Day by the Managing Owner in exchange for the Creation Basket Capital Contribution, which the Managing Owner receives from Participants, or Redemption Distributions, which the Managing Owner delivers to Participants, in each case on behalf of the Trust. Participants will be required to pay a nonrefundable per order transaction fee of $[-] to the Managing Owner (the “Transaction Fee”).

Each Participant is responsible for ensuring that the Creation Basket Capital Contribution it intends to transfer to the Trust in exchange for Creation Basket(s) is available for transfer to the Trust in the manner and at the times described in these Procedures.

Upon acceptance of the Participant Agreement by the Managing Owner, the Managing Owner will assign a personal identification number (a “PIN number”) to each Authorized Person authorized to act for the Participant. This will allow the Participant through its Authorized Person(s) to place Purchase Order Subscription Agreement(s) or Redemption Order(s) for Basket(s).

Important Notes:

•

Any Order is subject to rejection by the Managing Owner for the reasons set forth in the Trust Agreement or the Participant Agreement.

•

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

CREATION PROCESS

An order to purchase one or more Creation Baskets placed by a Participant with the Managing Owner by a telephone call placed by the Order Cut-Off Time on a Business Day (such day, “Purchase Order Subscription Date”) results in the issuance and delivery of Creation Basket(s) at noon, Eastern Time, on the Business Day immediately following the Purchase Order Subscription Date if the Managing Owner has received:

•

for its own account, the Transaction Fee, and

•

for the account of the Trust the Creation Basket Capital Contribution due from the Participant submitting the Purchase Order Subscription Agreement.

CREATION PROCEDURES

By the Order Cut-Off Time (Noon Eastern Time) on the Purchase Order Subscription Date, an Authorized Person of the Participant calls the Managing Owner at (-) [[—]] to notify the Managing Owner that the Participant wishes to place a Purchase Order and Subscription Agreement with the Managing Owner to create an identified number of Creation Baskets and to request that the Managing Owner provide an order number (an “Order Number”). Calls placed before the Order Cut-Off Time will be processed even if the call is taken after that time. The Authorized Person provides a PIN number as identification to the Managing Owner. The Managing Owner provides the Participant with an Order Number for the Participant’s Purchase Order and Subscription Agreement. The Participant then completes and faxes to the Managing Owner the Purchase Order Subscription Agreement included as Exhibit B to the Participant Agreement. The Purchase Order Subscription Agreement must be completed and also include the Authorized Person’s signature, the number of Creation Baskets being purchased, and the Order Number previously provided by the Managing Owner.

If the Managing Owner has not received the Purchase Order Subscription Agreement from the Participant within 15 minutes after the Managing Owner receives the phone call from an Authorized Person of the Participant referenced in item (1) above, the Managing Owner places a phone call to the Participant to enquire about the status of the Order. If the Participant does not fax the Purchase Order Subscription Agreement to the Managing Owner within 15 minutes after the Managing Owner’s phone call, the Participant’s Order is cancelled. The Managing Owner will then notify the Participant that the Order has been cancelled via telephone call.

If the Managing Owner has received the Participant’s Purchase Order and Subscription Agreement on time in accordance with the preceding timing rules, then by [[-] a.m./p.m.] Eastern Time the Managing Owner returns to the Participant a copy of the Purchase Order and Subscription Agreement submitted, marking it “Accepted.”

As promptly as practicable following the publication⁶ of the net asset value of the Trust and the net asset value per Share of the Shares on the Purchase Order Subscription Date, the Managing Owner shall communicate to the Participant the amount of cash necessary for the Creation Basket Capital Contribution and details of the method of payment required for the Creation Basket Capital Contribution.

If the Managing Owner rejects a Purchase Order Subscription Agreement pursuant to the Trust Agreement or the Participant Agreement, the Managing Owner will notify the Participant whose Purchase Order Subscription Agreement was rejected.

At noon, Eastern Time, on the Business Day immediately following the Purchase Order Subscription Date, the Managing Owner authorizes the creation and issuance of the Creation Baskets ordered by each Participant on the Purchase Order Subscription Date for which the Managing Owner has received confirmation of receipt of (A) for its own account, the Transaction Fee, and (B) for the account of the Trust, the Creation Basket Capital Contribution due from the Participant submitting the Purchase Order Subscription Agreement.

The Managing Owner will cause the Trust to deposit the Creation Basket with the Depository in accordance with the Depository’s customary procedures, for the credit of the account of the Participant that placed the Purchase Order Subscription Agreement.

If by noon, Eastern Time, on the Business Day immediately following the Purchase Order Subscription Date, the Managing Owner has not received confirmation of receipt of (A) for its own account, the Transaction Fee, and (B) for the account of the Trust, the Creation Basket Capital Contribution due from the Participant submitting the Purchase Order Subscription Agreement, the Participant will be charged by the Managing Owner an additional processing charge of $[-].

REDEMPTION PROCESS

An order to redeem one or more Redemption Baskets placed by a Participant with the Managing Owner by a telephone call placed by the Order Cut-off Time on a Business Day (such day, “Redemption Order Date”) results in the following taking place by noon, Eastern Time, on the Business Day immediately following the Redemption Order Date (the “Redemption Settlement Time”):

•

if the Fund’s account at the Depository has by the Redemption Settlement Time been credited with the Redemption Baskets being tendered for redemption and the Managing Owner has by such time received the Transaction Fee, the Managing Owner shall deliver the Redemption Distribution through the Depository to the account of the Participant as recorded on the book entry system of the Depository.

REDEMPTION PROCEDURES

By the Order Cut-off Time (Noon Eastern Time), an Authorized Person of the Participant calls the Managing Owner at (-) [[—]] to notify the Managing Owner that the Participant wishes to place a Redemption Order with the Managing Owner to redeem an identified number of Redemption Baskets and to request that the Managing Owner provide an Order Number. Calls placed before the Order Cut-Off Time will be processed even if the call is taken after that time. The Authorized Person provides a PIN number as identification to the Managing Owner. The Managing Owner provides the Participant with an Order Number for the Participant’s Redemption Order Form. The Participant then completes and faxes to the Managing Owner the Redemption Order Form included as Exhibit C to the Participant Agreement. The Redemption Order Form must include the Authorized Person’s signature, the number of Redemption Baskets redeemed, and the Order Number previously provided by the Managing Owner.

If the Managing Owner has not received the Redemption Order Form from the Participant within 15 minutes after the Managing Owner receives the phone call from an Authorized Person of the Participant referenced in item (1) above, the Managing Owner places a phone call to the Participant to inquire about the status of the Order. If the Participant does not fax the Redemption Order Form to the Managing Owner within 15 minutes after the Managing Owner’s phone call, the Participant’s Order is cancelled. The Managing Owner will then notify the Participant that the Order has been cancelled via telephone call.

If the Managing Owner has received the Participant’s Redemption Order Form on time in accordance with the preceding timing rules, then by [[-] a.m./p.m.] Eastern Time the Managing Owner returns to the Participant a copy of the Redemption Order Form submitted, marking it “Affirmed.”

As promptly as practicable following the publication⁷ of the net asset value of the Trust and the net asset value per Share of the Shares on the Redemption Order Date, the Managing Owner shall communicate to the Participant the amount of cash to be delivered in the Redemption Distribution.

If the Managing Owner rejects a Redemption Order pursuant to the Trust Agreement or the Participant Agreement, the Managing Owner will notify the Participant whose Redemption Order was rejected and the amount of cash contained in the rejected Redemption Order.

By the Redemption Settlement Time, if the Managing Owner’s account at the Depository has by such time been credited with the Redemption Baskets being tendered for redemption and the Managing Owner has by such time received the Transaction Fee, the Managing Owner shall deliver the Redemption Distribution through the Depository to the account of the Participant as recorded on the book entry system of the Depository.

If by the Redemption Settlement Time the Managing Owner has not received from a redeeming Participant all Redemption Baskets comprising the Redemption Order, the Managing Owner will (i) settle the Redemption Order to the extent of whole Redemption Basket(s) received from the Participant and (ii) keep the redeeming Participant’s Redemption Order open until noon, Eastern Time, on the first Business Day following the Redemption Settlement Date as to the balance of the Redemption Order (such balance, the “Suspended Redemption Order”).

If the Redemption Basket(s) comprising the Suspended Redemption Order are credited to the Trust’s account at the Depository by noon, Eastern Time, on such following Business Day, the Redemption Distribution with respect to the Suspended Redemption Order shall be paid in the manner provided in item (6) above.

If by such Redemption Settlement Time the Fund has not received from the redeeming Participant all Redemption Baskets comprising the Suspended Redemption Order, the Managing Owner will settle the Suspended Redemption Order to the extent of whole Redemption Baskets then received and any balance of the Suspended Redemption will be cancelled. Notwithstanding the foregoing, when and under such conditions as the Managing Owner may from time to time determine, the Managing Owner shall be authorized to deliver the Redemption Distribution notwithstanding that a Redemption Basket has not been credited to the Trust’s account at the Depository if the Participant has collateralized its obligation to deliver the Redemption Basket on such terms as the Managing Owner may, in its sole discretion, from time to time agree.

10.

If, by the Redemption Settlement Time the Trust has not received from a redeeming Participant all Redemption Baskets comprising the Redemption Order or the Suspended Redemption Order, as applicable, the Participant will be charged by the Managing Owner an additional processing charge of $[-].

⁷	The publication of the net asset value of the Trust and the net asset value per Share will be calculated after the closing time of the NYSE Arca, Inc. or the last to close of the exchanges on which the Trust’s futures contracts are traded, whichever is later.
