Redemption Agent nor the Trustee shall be liable to any person for rejecting a Redemption Order. Should the Creation and Redemption Agent (acting on behalf of, and in consultation with, the Trustee) elect to accept such Redemption Order, it shall
communicate its decision to the Authorized Participant by sending to the Authorized Participant, via facsimile or electronic mail message, no later than 7:00 p.m. (New York time) on the same Business Day for such Redemption Order, a confirmation of
the Creation and Redemption Agent’s acceptance of the Redemption Order. Prior to the transmission of the Creation and Redemption Agent’s confirmation of acceptance, a Redemption Order will only represent the Authorized Participant’s

Participant specified in such confirmation with the applicable Basket Constituents. Upon such Delivery, the Settlement Agent will then cancel the iShares so redeemed on behalf of the Trustee. 

e. In connection with any Redemption Order, the Authorized Participant authorizes the Settlement Agent to deduct a transaction fee per
Basket in the amount of the Applicable Transaction Fee from the applicable Basket Constituents credited to the applicable account of the redeeming Authorized Participant.

DTC shall not have been credited with the total number of iShares corresponding to the total number of Baskets

and authority to surrender to the Settlement Agent for redemption the corresponding iShares, and upon such surrender the Trust will acquire good and unencumbered title to such iShares, free and clear of all liens, charges, duties imposed on the
transfer of assets and encumbrances and not subject to any adverse claims, transferability restrictions (whether arising by operation of law or otherwise), loan, pledge, repurchase or securities lending agreements or other arrangements which would
preclude the delivery of such iShares on a “regular way” basis. 
 Section 1.08. Certain Payments or
Distributions. 
 a. With respect to any Purchase Order, the Trust acknowledges and agrees to return to the Authorized
Participant any payment, distribution or other amount paid to the Trust in respect of any Basket Constituents transferred to the Trust that, based on the valuation of the Basket Constituents at the time of transfer, should have been paid to the
Authorized Participant. Likewise, the Authorized Participant acknowledges on behalf of itself and any Authorized Participant Client and agrees to return to the Trust any payment, distribution or other amount paid to the Authorized Participant or any
Authorized Participant Client in respect of any Basket Constituents transferred to the Trust that, based on the valuation of the Basket Constituents at the time of transfer, should have been paid to the Trust. 

b. With respect to any Redemption Order, the Authorized Participant on behalf of itself and any Authorized Participant Client
acknowledges and agrees to return to the Trust any payment, distribution or other amount paid to it or an Authorized Participant Client in respect of any property transferred to the Authorized Participant or any Authorized Participant Client that,
based on the valuation of such property at the time of transfer, should have been paid to the Trust. The Trust is entitled to reduce the amount of any property due to the Authorized Participant or any Authorized Participant Client by an amount equal
to any payment, distribution or other sum to be paid to the Authorized Participant or to the Authorized Participant Client in respect of any property transferred to the Authorized Participant or any Authorized Participant Client that, based on the
valuation of such property at the time of transfer, should be paid to the Trust. Likewise, the Trust acknowledges and agrees to return to the Authorized Participant or any Authorized Participant Client any payment, distribution or other amount paid
to it in respect of any iShares transferred to the Trust that, based on the valuation of such iShares at the time of transfer, should have been paid to the Authorized Participant or such Authorized Participant Client.

 ARTICLE II 
 AUTHORIZED REPRESENTATIVES 
 Section 2.01. Certification. Concurrently
with the execution of the Authorized Participant Agreement, and as requested from time to time by the Trustee but no less frequently than annually, the Authorized Participant shall deliver to the Trustee a certificate signed by the Authorized
Participant’s Secretary or other duly authorized official setting forth the names, e-mail addresses and telephone and facsimile numbers of all persons authorized to give instructions relating to any activity contemplated hereby or any other
notice, request or instruction on behalf of the Authorized Participant (each an “Authorized Representative”). Such certificate may be accepted and relied upon by the Trustee as conclusive evidence of the facts set forth therein and
shall be considered to be in full force and effect until (i) receipt by the Trustee of a superseding certificate in a form approved by the Trustee bearing a subsequent date, or (ii) termination of the Authorized Participant Agreement.

 Section 2.02. PIN Numbers. The Creation and Redemption Agent shall issue to each Authorized Participant a unique
personal identification number (“PIN Number”) by which such Authorized Participant shall be identified and instructions issued by the Authorized Participant shall be authenticated. The PIN Number shall be kept confidential and only
provided to Authorized Representatives. The Authorized Participant may revoke the PIN Number at any time upon written notice to the Creation and Redemption Agent, and the Authorized Participant shall be responsible for doing so in the event that it
becomes aware that an unauthorized person has received access to its PIN Number or has or intends to use the PIN Number in an unauthorized manner. Upon receipt of such written request, the Creation and Redemption Agent shall, as promptly as
practicable, de-activate the PIN Number. If an Authorized Participant’s PIN Number is changed, the new PIN Number will become effective on a date mutually agreed upon by the Authorized Participant and the Creation and Redemption Agent. The
Authorized Participant agrees that, absent the Creation and Redemption Agent’s fraud, willful misconduct or failure to cancel the PIN Number promptly following a written request to do so from the Authorized Participant or the termination of the
Authorized Participant Agreement, none of the Trust, the Trustee or the Creation and Redemption Agent shall be liable for losses incurred by the Authorized Participant as a result of unauthorized use of the Authorized Participant’s PIN Number
prior to the time the Authorized Participant provides notice to the Creation and Redemption Agent of the termination or revocation of authority pursuant to Section 2.03. 
 Section 2.03. Termination of Authority. Upon the termination or revocation of authority of an Authorized Representative by the Authorized Participant, the Authorized Participant shall
(i) give immediate written notice of such fact to the Creation and Redemption Agent and such notice shall be effective upon receipt by the Creation and Redemption Agent; and (ii) request a new PIN Number. The Creation and Redemption Agent
shall, as promptly as practicable, de-activate the PIN Number upon receipt of such written notice. 
 Section 2.04.
Verification. The Creation and Redemption Agent may assume that all instructions issued to it using the Authorized Participant’s PIN Number have been properly placed by Authorized Representatives, unless the Creation and Redemption Agent
has actual knowledge to the contrary or the Authorized Participant has revoked its PIN Number. The Creation and Redemption Agent shall have no duty to verify that an Order has been placed by an Authorized Representative. The Authorized Participant
agrees that the Creation and Redemption Agent shall not be responsible for any losses incurred by the Authorized Participant as a result of an Authorized Representative identifying himself or herself as a different Authorized Representative or an
unauthorized person identifying himself or herself as an Authorized Representative, unless the Creation and Redemption Agent previously received from the Authorized Participant written notice to revoke its PIN Number.

 ARTICLE III 
 STATUS OF THE AUTHORIZED PARTICIPANT 
 Section 3.01. Clearing Status.
The Authorized Participant represents, covenants and warrants that, as of the date of execution of the Authorized Participant Agreement, and at all times during the term of the Authorized Participant Agreement, the Authorized Participant is and will
be entitled to use the clearing and settlement services of each of the national clearing and settlement organizations through which, in compliance with the Procedures, the transactions contemplated hereby will clear and settle. Any change in the
foregoing status of the Authorized Participant shall terminate the Authorized Participant Agreement and the Authorized Participant shall give prompt written notice thereof to the Creation and Redemption Agent. 

Section 3.02. Registration Status. The Authorized Participant represents and warrants that, unless Section 3.03 is
applicable to it, it is (i) registered as a broker-dealer under the Securities Exchange Act of 1934, as amended, (ii) qualified to act as a broker or dealer in the states or other jurisdictions where it transacts business to the extent so
required by applicable law, (iii) a member in good standing of the NASD and (iv) if required in connection with its activities hereunder, registered as a futures commission merchant under the Commodity Exchange Act, as amended and a member
in good standing of the National Futures Association. The Authorized Participant agrees that it will maintain such registrations, qualifications, and membership in good standing and in full force and effect throughout the term of the Authorized
Participant Agreement. The Authorized Participant further agrees to comply with all Federal laws, the laws of the states or other jurisdictions concerned, and the rules and regulations promulgated thereunder, to the extent such laws and regulations
are applicable to the Authorized Participant’s transactions in iShares, and with the Constitution, By-Laws and Conduct Rules of the NASD applicable to its activities as an Authorized Participant, that it will not offer or sell iShares in any
state or jurisdiction where they may not lawfully be offered and/or sold, and without limiting the foregoing that it will comply with any applicable transfer restrictions with respect to iShares set forth in the current Prospectus. 

Section 3.03. Foreign Status. If the Authorized Participant is offering and selling iShares 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 the NASD as set forth in the preceding paragraph, the Authorized Participant nevertheless agrees to observe
the applicable laws of the jurisdiction in which such offer and/or sale is made (e.g., it will not offer or sell iShares in any state or jurisdiction where they may not lawfully be offered and/or sold), to comply with the full disclosure
requirements of the 1933 Act and the regulations promulgated thereunder and to conduct its business in accordance with the spirit of the NASD Conduct Rules. 
 Section 3.04. Futures Account. The Authorized Participant represents and warrants that it will arrange to receive any futures contracts owing to the Authorized Participant upon settlement of a
Redemption Order at an account it establishes through a member of the applicable Futures Exchange’s associated clearing organization (which may include such Authorized Participant), and will maintain such an account at all times it is an
Authorized Participant. The Authorized Participant will provide notice of such account to the Settlement Agent upon request. 

Section 3.05. Compliance with Certain Laws. If the Authorized Participant is subject to the requirements of the Uniting and
Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism (“U.S.A. PATRIOT Act”), the Authorized Purchaser is in compliance with the anti-money laundering and related provisions of the U.S.A.
PATRIOT Act. 

  
 S2-4

 Section 3.06. Authorized Participant Status. 

a. The Authorized Participant understands and acknowledges that the method by which Baskets of iShares will be created and traded may
raise certain issues under applicable securities laws. For example, because new Baskets of iShares may be issued and sold by the Trust on an ongoing basis, at any point a “distribution”, as such term is used in the 1933 Act, may occur. The
Authorized Participant understands and acknowledges that some activities on its part, depending on the circumstances, may result in its being deemed a participant in a distribution in a manner which could render it a statutory underwriter and
subject it to the prospectus delivery and liability provisions of the 1933 Act. 
 b. The Sponsor shall ensure that the
Prospectus contains an accurate and current listing of Authorized Participants. 
 ARTICLE IV 

ROLE OF AUTHORIZED PARTICIPANT 
 Section 4.01. Independent Contractor. The Authorized Participant acknowledges and agrees that for all purposes of the Authorized Participant Agreement, the Authorized Participant will be
deemed to be an independent contractor, and will have no authority to act as agent for the Trust or the Trustee in any matter or in any respect. The Authorized Participant agrees to make itself and its employees available, upon request, during
normal business hours to consult with the Trustee, the Sponsor or their designees concerning the performance of the Authorized Participant’s responsibilities under the Authorized Participant Agreement; provided, however, that the
Authorized Participant shall be under no obligation to divulge or otherwise disclose any information that the Authorized Participant reasonably believes (i) it is under legal obligation not to disclose, or (ii) it is confidential or
proprietary in nature. 
 Section 4.02. Rights and Obligations of DTC Participant. In executing the Authorized
Participant Agreement, the Authorized Participant agrees in connection with any purchase or redemption transactions in which it acts for an Authorized Participant Client or for any other DTC Participant or indirect participant, or any other person
on whose behalf it holds iShares, that it 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 under the Procedures.

 Section 4.03. Beneficial Owner Communications. The Authorized Participant agrees, subject to any limitations
arising under federal or state securities laws relating to privacy or other obligations it may have to its customers, to assist the Trustee or the Sponsor in determining the ownership level of each beneficial owner relating to positions in iShares
that the Authorized Participant may hold as record holder or that may be held through the Authorized Participant as a DTC Participant. In addition, the Authorized Participant agrees, in accordance with applicable laws, rules and regulations, at the
request of the Sponsor or the Trustee to forward to such beneficial owners written materials and communications received from the requesting party in sufficient quantities to allow mailing thereof to such beneficial owners, including notices, annual
reports, disclosure or other informational materials and any amendments or supplements thereto that may be required to be sent by the Sponsor or the Trustee to such beneficial owners pursuant to the Trust Agreement or applicable law or regulation,
or that the Sponsor or the Trustee reasonably wishes to distribute, at its own expense, to such beneficial owners. 

  
 S2-5

 ARTICLE V 
 TAX MATTERS 
 Section 5.01. Tax Basis of Assets Contributed Upon
Creation. With respect to any Creation of iShares, the Authorized Participant on behalf of itself and any Authorized Participant Client agrees that any property contributed in consideration for the creation of iShares shall have a basis for tax
purposes equal to the fair market value of that property, and acknowledges that the Trust will rely upon such fair market value basis for purposes of determining and allocating items of income, gain, loss, deduction, basis and other tax items.

 Section 5.02. Tax Basis of Basket Constituents Received Upon Redemption. 

a. With respect to any Redemption of iShares held by an Authorized Participant for its own account, the Authorized Participant
acknowledges that the basis for tax purposes in Basket Constituents that it receives from the Trust in consideration for a redemption of iShares may be more or less than the fair market value of the Basket Constituents or the Authorized
Participant’s basis in the iShares redeemed. The Authorized Participant will determine its basis for tax purposes in any Basket Constituent it receives from the Trust in consideration for a redemption of iShares by reference to the tax basis of
such Basket Constituent on the books of the Trust immediately prior to the redemption, as such amount is reported to the Authorized Participant by the Settlement Agent, subject to adjustment as required under Section 732 or other applicable
law. The Authorized Participant will report any built-in gain or loss on Index Futures that it receives from the Trust on redemption of iShares under the rules of section 1256 of the Code (absent a valid election to do otherwise), and, to the extent
applicable, will report any offsetting gain or loss on the remaining iShares held by the Authorized Participant under the rules of section 475 of the Code. The Authorized Participant acknowledges that such reporting may result in a mismatch in the
character or other tax attributes of gain or loss from Index Futures and iShares. 
 b. With respect to any Redemption of
iShares held by an Authorized Participant for an Authorized Participant Client, the Authorized Participant acknowledges on behalf of itself and such Authorized Participant Client that the basis for tax purposes in Basket Constituents received from
the Trust in consideration for the redemption of iShares may be more or less than the fair market value of the Basket Constituents or the Authorized Participant Client’s basis in the iShares redeemed. To the extent that the Authorized
Participant reports to an Authorized Participant Client, the Internal Revenue Service or any other person the basis for tax purposes of any Basket Constituents it receives from the Trust in consideration for a redemption of iShares on behalf of an
Authorized Participant Client, the Authorized Participant will determine its basis by reference to the tax basis of such Basket Constituents on the books of the Trust immediately prior to the redemption, as such amount is reported to the Authorized
Participant by the Settlement Agent, subject to adjustment as required under Section 732 or other applicable law. The Authorized Participant will report any other tax items of an Authorized Participant Client (e.g., basis in iShares, or
gain or loss amounts) in a manner consistent with the preceding sentence. 
 c. The Authorized Participant acknowledges on
behalf of itself and any Authorized Participant Client that, to the extent that such Participant or Client is subject to the mark-to-market rules of section 475 of the Code, the basis of iShares and of any assets of the Trust shall be determined for
purposes of sections 734(b) and 743(b) of the Code and for the purposes of the provisions of this Article V by treating such mark-to-market as having no effect on such basis. 

  
 S2-6

 Section 5.03. Treatment of Redemptions as Partial or Complete Redemptions.

 a. The Authorized Participant represents with respect to each redemption of iShares held by the Authorized Participant for its
own account that the receipt of Basket Constituents from the Trust in connection with such redemption is a distribution other than in liquidation of the Authorized Participant’s interest in iShares (a “partial redemption”), unless it
notifies the Trust or its agent prior to the receipt of the Basket Constituents that such distribution is in liquidation of the Authorized Participant’s interest in iShares (a “complete redemption”). The Authorized Participant
acknowledges that the Trust may report gain or loss and other tax items including the allocation of basis and adjustments to basis in reliance upon the assumption that any redemption of iShares is a partial redemption unless such notice is timely
provided. The Authorized Participant will notify the Trust or its agent within five Business Days of the receipt of the Basket Constituents of (i) any gain or loss arising from a redemption of iShares by the Authorized Participant in exchange
for Basket Constituents, and (ii) any difference between the tax basis of such Basket Constituents on the books of the Trust immediately prior to the redemption, as such amount is reported to the Authorized Participant, and the basis of the
distributed Basket Constituents to the Authorized Participant (such gain or loss or basis difference, “section 734(b) items”), in a manner sufficient for the Trust to adjust the basis of undistributed property held by the Trust under
section 734(b) of the Code. 
 b. To the extent that an Authorized Participant acts on behalf of an Authorized Participant
Client in connection with a redemption of iShares, the Authorized Participant will inform the Trust or its agent prior to the receipt of the Basket Constituents of any such redemption that constitutes a complete redemption, to the extent that such
information is available to the Authorized Participant (for example, because the Client redeems all iShares that it holds through the Authorized Participant). The Authorized Participant acknowledges on behalf of itself and any Authorized Participant
Client that redeems iShares that the Trust may report gain or loss and other tax items including the allocation of basis and adjustments to basis in reliance upon the assumption that any redemption of iShares is a partial redemption unless such
notice is timely provided. The Authorized Participant will make commercially reasonable efforts to assist the Trust in determining the amount of section 734(b) items, if any, with respect to a redemption of iShares on behalf of an Authorized
Participant Client. 
 Section 5.04. Tax Reporting. 

a. An Authorized Participant will provide tax reporting information with respect to the Trust to or for the benefit of taxpayers for whom
the Authorized Participant holds iShares as a nominee as required by law. 
 b. An Authorized Participant will furnish
information to the Trust with respect to any taxpayer for whom the Authorized Participant holds iShares as a nominee as required under Treasury regulation section 1.6031(c)-1T or any successor thereto in addition to any information required by other
provisions of this Article V. 
 c. An Authorized Participant will use commercially reasonable efforts to ensure that any
taxpayer for whom the Authorized Participant holds iShares as a nominee has provided IRS Form W-9, W-8BEN, or other forms or documentation qualifying as a withholding certificate or documentary evidence or other appropriate documentation within the
meaning of Treasury regulation section 1.1441-1(c) or any successor thereto, as necessary to establish an exemption from withholding tax and backup withholding tax with respect to income of the Trust allocable to such investor. The Authorized
Participant will act as an agent of the Trust in collecting and holding such forms or documentation, and annually will provide a copy of such forms to the Trust or its agent. Upon reasonable request by the Trust or its agent, the Authorized
Participant will provide the originals of such forms or documentation to the 

  
 S2-7

 
extent held by the Authorized Participant at that time and will assist the Trust in obtaining such original forms or documentation (or, to the extent originals are not available, copies thereof)
from investors or other nominees to the extent not held by the Authorized Participant. The provisions of this Section 5.04(c) of the Authorized Participant Agreement are subject to, and may be modified by, any agreements between the Trustee, on
behalf of the Trust, and an Authorized Participant separate and apart from the Authorized Participant Agreement, that provide otherwise. 
 ARTICLE VI 
 MARKETING MATERIALS AND REPRESENTATIONS 

Section 6.01. Authorized Participant’s Representation. The Authorized Participant represents, warrants and agrees that
it will not make, or permit any of its representatives to make, any representations concerning iShares other than those contained in the Trust’s then current Prospectus or in any promotional materials or sales literature furnished to the
Authorized Participant by the Sponsor. The Authorized Participant agrees not to furnish or cause to be furnished to any person or display or publish any information or materials relating to iShares (including, without limitation, promotional
materials and sales literature, advertisements, press releases, announcements, statements, posters, signs or other similar materials), except such information and materials as may be furnished to the Authorized Participant by the Sponsor and such
other information and materials as may be approved in writing by the Sponsor. The Authorized Participant understands that the Trust will not be advertised as offering redeemable securities, and that any advertising materials will prominently
disclose that the iShares are not redeemable units of beneficial interest in the Trust. Notwithstanding the foregoing, the Authorized Participant may, without the written approval of the Sponsor, prepare and circulate in the regular course of its
business reports, research or similar materials that include information, opinions or recommendations relating to iShares (i) for public dissemination, provided that such reports, research or similar materials compare the relative merits and
benefits of iShares with other products and are not used for purposes of marketing iShares and (ii) for internal use by the Authorized Participant. 
 Section 6.02. Prospectus. 
 a. The Sponsor will provide, or cause to be
provided, to the Authorized Participant copies of the then current Prospectus and any printed supplemental information in reasonable quantities upon request. The Sponsor will notify the Authorized Participant when a revised, supplemented or amended
Prospectus for the iShares is available, and make available to the Authorized Participant copies of such revised, supplemented or amended Prospectus at such time and in such quantities as may be reasonable to permit the Authorized Participant to
comply with any obligation the Authorized Participant may have to deliver such Prospectus to its customers. The Sponsor shall be deemed to have complied with this Section 6.02 when the Authorized Participant has received such revised,
supplemented or amended Prospectus by e-mail, in printable form, with such number of hard copies as may be agreed from time to time by the parties promptly thereafter. 
 b. The Authorized Participant represents and warrants to the Sponsor that it will deliver the then current Prospectus upon any sale by it of iShares (other than a redemption) or, if applicable, a notice
consistent with Rule 173 under the 1933 Act in lieu of a Prospectus, to the extent so required by applicable law.

believed by such Indemnified Party to be genuine and to have been given by the Authorized Participant.

 A-1Form of Investment Advisory Agreement

 Exhibit 10.1 
 INVESTMENT ADVISORY AGREEMENT 
 THIS INVESTMENT
ADVISORY AGREEMENT (this “Agreement”) is dated as of [                    ] between BlackRock Fund Advisors, a California
corporation (“Advisor”), and BlackRock Institutional Trust Company, N.A., a national banking association acting not in its individual capacity but solely as trustee (in such capacity, the “Trustee”) of
the iShares® Dow Jones-UBS Roll Select Commodity Index Trust, a Delaware statutory trust (the
“Trust”). 
  

	1.	 The Trust. The Trust is a commodity pool as defined in the Commodity Exchange Act (the “CEA”) and the applicable
regulations of the Commodity Futures Trading Commission (the “CFTC”). The Trust is operated by
iShares® Delaware Trust Sponsor LLC, a Delaware limited liability company, and a commodity pool operator
registered under the CEA, acting in its capacity as sponsor of the Trust (in such capacity, the “Sponsor”). The Trust is not an investment company under the Investment Company Act of 1940, as amended (the “Investment Company
Act”), and is not required to register under the Investment Company Act. 

  

	2.	Appointment. The Trust hereby appoints Advisor as commodity trading advisor for such portion of the assets of the Trust, that may be deposited, from time to
time, in a separate account or accounts (collectively, the “Accounts”) to be managed by Advisor under this Agreement, with full power to supervise and direct the investment of the assets of the Accounts as set forth herein. Advisor
hereby accepts such appointment and agrees to render advisory services on the terms and conditions set forth in this Agreement. Advisor shall be deemed to be an independent contractor of the Trust and, except to the extent authorized herein, shall
have no authority to act for or represent the Trust as its agent. 

  

	3.	Delegation. The Trust acknowledges that Advisor may delegate various advisory services with respect to the Accounts. In the event of any such delegation, such
party to whom Advisor delegates various advisory services shall be bound to the terms of this Agreement to the same extent as Advisor. Advisor shall, at its expense, employ or associate with itself such persons as Advisor believes appropriate to
assist it in performing its obligations under this Agreement. 

  

	4.	Investment Direction. Advisor will manage the Accounts in accordance with Advisor’s best judgment and consistent with the guidelines attached as Schedule
A (the “Investment Guidelines”), as they may be modified from time to time by the written agreement of Advisor and the Sponsor on behalf of the Trust. 

 

	5.	Custodian and Clearing FCM. The Trust has appointed State Street Bank and Trust Company, as custodian (the “Custodian”), and UBS Securities LLC,
as clearing futures commission merchant (the “Clearing FCM”) for the Accounts. Advisor shall not receive, and shall at no time be in possession of, the assets comprising the Accounts. 

 

	6.	 Reporting. Advisor will submit to the Trust reports appraising the Accounts at current market value as agreed between Advisor and the Sponsor.
Advisor shall advise the Trust 

  
 1 

	 	
at such times as the Trust may specify, of such investments made and the reasons for making a particular investment. Advisor will be available at reasonable times by prior arrangement to discuss
the management of the Accounts with the Trust or its designee. Any written reports supplied by Advisor to the Trust discussing the management of the Accounts are intended solely for the benefit of the Trust, and the Trust agrees that it will not
disseminate such reports to any other party (other than the Trust’s professional advisors) without the prior consent of Advisor, except as may be required by applicable law. Advisor will provide to the Sponsor any information concerning the
Advisor or its trading program that is necessary for the Sponsor to prepare any disclosure document for investors in the Trust or any periodic or other reports that the Trust may be required to file or furnish to any regulators, including the
Securities and Exchange Commission and the CFTC. 

  

	7.	Other Accounts. The Trust understands and acknowledges that Advisor performs commodity trading advisory services for various persons other than the Trust. The
Trust acknowledges that Advisor may give advice and take action concerning such persons that may be the same as, similar to or different from the advice given, or the timing and nature of action taken, concerning the Accounts. Except to the extent
necessary to perform Advisor’s obligations under this Agreement, nothing herein shall be deemed to limit or restrict the right of Advisor, or any affiliate of Advisor or any employee of Advisor to engage in any other business or to devote time
and attention to the management or other aspects of any other business, whether of a similar or dissimilar nature, or to render services of any kind to any other corporation, firm, individual or association. 

 

	8.	Fees. The Sponsor shall pay Advisor a fee determined by Advisor and the Sponsor, from time to time, for its services as Advisor hereunder.

  

	9.	Representations. The Trust represents and warrants that: (a) it has been duly organized and is validly existing under the law of the state of its
organization, (b) it is duly authorized to execute, deliver and perform this Agreement and has taken all action necessary to authorize its execution, delivery and performance, including the obtaining of any necessary governmental consents,
(c) the execution, delivery and performance of this Agreement, including the Investment Guidelines, does not and will not conflict with or violate any provision of law, rule, regulation, governing document of the Trust, contract, deed of trust,
or other instrument to which the Trust is a party or to which any of the Trust’s property is subject, (d) this Agreement is a valid and binding obligation enforceable against the Trust in accordance with its terms (subject to applicable

 SCHEDULE A 
 INVESTMENT GUIDELINES 
  

	A.	INVESTMENT OBJECTIVE 

 The
investment objective of the Trust is to seek investment results that correspond generally to the performance of the Dow Jones-UBS Roll Select Commodity Index Total Return (the “Index”), before payment of expenses and liabilities.

  

	B.	INVESTMENT STRATEGY 

 The
Trust will seek to achieve its exposure to the Index by investing all of the Trust’s assets to establish positions in Index Futures and Collateral Assets. Applicable margin requirements on the Trust’s Index Future positions will be
satisfied through the transfer of Collateral Assets or the proceeds thereof. “Index Futures” are futures contracts on the Dow Jones-UBS Roll Select Commodity Index that are listed on a “designated contract market,” as
defined in the CEA. “Collateral Assets” are cash, U.S. Treasury securities or other short-term securities and similar securities that are eligible as margin deposits for Index Futures under the rules of the applicable designated
contract market. 
  

	C.	RESTRICTIONS 

 Advisor
shall not engage in any activity designed to obtain a profit from, or ameliorate losses caused by changes in the level of the Index or the value of the Index Futures or the Collateral Assets, including making use of any of the hedging techniques
available to professional commodity futures investors to attempt to reduce the risks of losses resulting from commodity price decreases.
