EXHIBIT 4.3 
  
 FORM OF

 DB COMMODITY INDEX TRACKING FUND 
 PARTICIPANT AGREEMENT 
  
 This DB Commodity Index Tracking Fund Participant Agreement (the “Agreement”), dated as of                     , is entered into
by and among                      (the “Authorized Participant”), DB Commodity Index Tracking Fund, a Delaware statutory trust (the
“Trust”), and DB Commodity Services LLC, a Delaware limited liability company, as managing owner of the Trust (the “Managing Owner”). 
  
 SUMMARY 
  
 As provided in the 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 two hundred
thousand (200,000) 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.: 333-125325), 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 (the “Prospectus”) included therein. 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 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. 
  
 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 Securities Act of 1933, as amended (“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 which 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” portion 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). 
  
 Capitalized terms used but not 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 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(c) applies, the Authorized Participant either (i) is registered as a broker-dealer under the Securities Exchange Act
of 1934, as amended (“1934 Act”), and is a member in good standing of 

 
the National Association of Securities Dealers, Inc. (the “NASD”), or (ii) is exempt from being, or otherwise is not required to be, licensed as a
broker-dealer or a member of the NASD, 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 will 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 will comply with all applicable federal laws, 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 the NASD (if it is a NASD member), and will not offer or sell Shares in any state or jurisdiction where they may not lawfully be offered and/or
sold. 
  
 (c) 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 the NASD as set forth in Section 2(b) above, the
Authorized Participant will (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 NASD Conduct Rules. 
  
 (d) 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. 
  
 (e) The Authorized Participant hereby covenants and agrees, with respect to each party for which the
Authorized Participant is acting (whether such party is a customer or otherwise) in connection with the creation of a Basket and to whom the Authorized Participant delivers a Prospectus (each a “Prospective Participant”), that the
Authorized Participant shall obtain from such Prospective Participant an acknowledgement from such Prospective Participant of receipt of such Prospectus in accordance with Commodity Futures Trading Commission Regulation 4.21(b), to the extent
applicable, prior to the submission of any Purchase Order Subscription Agreement in respect of such Basket. 
  
 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 will 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 will comply with such procedures.
Redemption Orders shall not be made or processed during the Initial Offering Period. The Authorized Participant acknowledges and agrees that orders to create Baskets submitted during the Initial Offering Period will be processed at the end of the
Initial Offering Period and that the Creation Basket Capital Contribution amount in respect of such orders during such period is $5 million, which shall be deposited in escrow in accordance with instructions from the Managing Owner as described in
the Prospectus during the period from the Purchase Order Subscription Date through the end of the Initial Offering Period or earlier termination of the offering of shares. 
  
 (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 

  

 2 

 
control of the Managing Owner make it for all practical purposes not feasible to process creations of 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 American Stock Exchange 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. (a) 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 applicable to such creation or redemption. The initial Transaction
Fee shall be five hundred dollars ($500). The Transaction Fee may be adjusted from time to time as set forth in the Trust Agreement and Prospectus. As described in the Procedures, in the case of a Redemption Order that is held open until the
Redemption Settlement Time, for each day (whether or not a Business Day) the Redemption Order is held open, the Authorized Participant will be charged by the Managing Owner the greater of (i) $300 and (ii) $30 times the number of Redemption Baskets
covered by the Redemption Order. 
  
 (b)
Upfront Selling Commissions. The Trust will rebate to the Authorized Participant an amount equal to 3.00% of the aggregate amount of all orders to purchase Creation Baskets received from the Authorized Participant during the Initial Offering
Period. 
  
 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 official, 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 is and shall be deemed to be an independent contractor and has 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) The Authorized Participant will maintain records of all
sales of Shares made by or through it and will furnish copies of such records to the Managing Owner upon the reasonable request of the Managing Owner. 
  
 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 attorney’s fees and the reasonable cost 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) 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 of the Trust as originally filed with 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 

  

 4 

 
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 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) If the indemnification provided for in this Section 8 is unavailable to an indemnified party under Sections 8(a) or 8(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 Managing Owner and the Trust, on the one hand, and by the Authorized Participant, 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 the Managing Owner and the Trust, on the one hand, and of the Authorized Participant, 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 benefits received by the Managing Owner and the Trust, on the one hand, and the Authorized Participant, on the other hand, shall be deemed
to be in the same respective proportions as the amount of cash transferred to the Trust under this Agreement on the one hand (expressed in dollars) bears to the amount of economic benefit received by the Authorized Participant in connection with
this Agreement on the other hand. To the extent applicable, the relative fault of the Managing Owner on the one hand and of the Authorized Participant on the other 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 the Managing Owner 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 8(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) The Managing Owner and the Authorized
Participant agree that it would not be just and equitable if contribution pursuant to this Section 8 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 8(d) above. The Authorized Participant shall not be required to contribute any amount in excess of the amount by which the total price at which the Shares created by the Authorized Participant and distributed to the public exceeds the
amount of any damage which the 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 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. 
  
 (f) The indemnity and contribution 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 and 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

  

 5 

 
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 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. Neither the Managing Owner 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); (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); 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 will 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 will 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 will file all such research reports, marketing material and sales literature related to the Shares with the NASD to the extent required by the NASD Conduct Rules.

  

 6 

 (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 may revoke the foregoing agreement at any time by delivering written notice to the Managing Owner and, whether or not such agreement is in effect, the Authorized Participant may, at any time,
request reasonable quantities of the Prospectus, and any supplements or amendments thereto or recirculation thereof, in paper form from the Managing Owner. 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 will 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 included within the Registration Statement 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) during the period prior to when the Managing Owner qualifies and in its sole discretion elects to file on Form S-3, the Managing Owner will remove such identification from the Prospectus in the amendment of the
Registration Statement next occurring after the date of the termination of this Agreement and, during the period after when the Managing Owner qualifies and in its sole discretion elects to file on Form S-3, the Managing Owner will promptly file a
current report on Form 8-K indicating the withdrawal of the Authorized Participant as an authorized participant of the Trust and (ii) the Managing Owner will promptly update the Trust’s website to remove any identification of the Authorized
Participant as an authorized participant of the Trust. 
  
 Section
13. Certain Covenants of the Managing Owner. The Managing Owner, on its own behalf and as sponsor of the Trust, covenants and agrees: 
  
 (a) to advise 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;

  
 (b) to furnish 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, (ii) a new Registration Statement is filed to register additional Shares in reliance on Rule 429, and (iii) there
is financial information incorporated by reference into the Registration Statement or the Prospectus, an opinion of either (x) Sidley Austin Brown & Wood LLP, counsel for the Managing Owner, or (y) special Delaware counsel for the Managing Owner

the 1933 Act (except such counsel need express no opinion as to any necessary qualification under the state securities or blue sky laws of any state or the laws of any jurisdictions outside the United States); 
  
 10. the execution, delivery and performance of this
Agreement by the Managing Owner, the issuance and delivery of the Shares by the Trust and the consummation by the Managing Owner on behalf of the Trust of the transactions contemplated hereby do not and will not conflict with, result in any breach

 15. the information in the Registration Statement and the Prospectus under the headings
“Risk Factors—Competing claims over ownership of intellectual property rights related to the Fund could adversely affect the Fund and an investment in the Shares,” “Material U. S. Federal Income Tax Considerations,” and
“Description of the Shares and the Master Fund Units; Certain Material Terms of the Trust Declarations,” insofar as such statements constitute a summary of documents or matters of law, are accurate in all material respects and present
fairly the information required to be shown. 
  
 In addition, such
counsel shall state that such counsel has participated in conferences with officers and other representatives of the Managing Owner, representatives of the independent public accountants of the Trust and representatives of the Authorized Participant
at which the contents of the Registration Statement and the Prospectus were discussed and, although such counsel is not passing upon and does not assume responsibility for the accuracy, completeness or fairness of the statements contained in the
Registration Statement or the Prospectus (except as and to the extent stated in subparagraphs (6) and (15) above), on the basis of the foregoing nothing has come to the attention of such counsel that causes them to believe that the Registration
Statement or any amendment thereto at the time such Registration Statement or amendment became effective contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the
statements therein not misleading, or that the Prospectus or any supplement thereto at the date of such Prospectus or such supplement, and at the time of purchase of the Shares by the Authorized Participant hereunder, contained an untrue statement
of a material fact or omitted 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 (it being understood that such counsel need
express no opinion with respect to the financial statements and schedules and other financial information included in the Registration Statement or the Prospectus); 
  
 (c) to cause KPMG LLP to deliver, at each time (i) the Registration Statement or the Prospectus is amended
or supplemented by the filing of a post-effective amendment, (ii) a new Registration Statement is filed to register additional Shares in reliance on Rule 429, and (iii) there is financial information incorporated by reference into the Registration
Statement or the Prospectus, letters dated such dates and addressed to the Authorized Participant, containing statements and information of the type ordinarily included in accountants’ letters to underwriters with respect to the financial
statements and other financial information contained in or incorporated by reference into the Registration Statement and the Prospectus; 
  
 (d) 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, (ii) a new Registration Statement is filed to register additional Shares in reliance on Rule 429, and (iii) there is financial information incorporated by reference into the Registration Statement or the
Prospectus, a certification by a duly authorized officer 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 as to matters covered thereby to the Authorized Participant; 
  
 (e) to cause the Trust to file a post-effective amendment to the Registration Statement no less frequently
than once per calendar quarter on or about the same time that the Trust files a quarterly or annual report pursuant to Section 13 or 15(d) of the 1934 Act (including the information contained in such report), until such time as the Trust’s
reports filed pursuant to Section 13 or 15(d) of the 1934 Act are incorporated by reference in the Registration Statement. 
  
 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. 
  

 9 

 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 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 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 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 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 amendment, modification or supplement has been agreed to, the
Managing Owner will mail a copy of the proposed amendment, modification or supplement to the Authorized Participant. For the purposes of this Agreement, mail will be deemed received by the recipient thereof on the third (3rd) 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 DB Commodity Index Tracking Fund Participant Agreement (other than this Agreement), the Managing Owner will 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 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. 
  

 10 

 (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 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 will be deemed to be an original copy of this Agreement and all of which, when taken together, will 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 article and 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 will 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 will so
notify the Authorized Participant immediately. 
  
 (k) No Strict Construction. The language used in this Agreement will be deemed to be the language chosen by the parties to express their mutual intent, and no rule of strict construction will be applied against any party. 

 

 11 

 (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 quasigovernmental 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.”

 PURCHASER’S REPRESENTATIONS AND WARRANTIES AND 
 POWER OF ATTORNEY 
  
 1.
CFTC Registration Status. The Authorized Participant either is not required to be registered with the Commodity Futures Trading Commission (“CFTC”) or to be a member of the National Futures Association
(“NFA”), or, if required to be so registered, is duly registered with the CFTC and is a member in good standing of the NFA. The Authorized Participant agrees to supply the Managing Owner with such information as the Managing Owner may
reasonably request in order to verify the foregoing representation. Vehicles for collective investment which acquire Shares may, as a result, themselves become “commodity pools” within the intent of applicable CFTC and NFA rules, and their
sponsors, accordingly, will be required to register as “commodity pool operators.” 
  
 2. Disclosure Document. The Authorized Participant has received the Trust’s Prospectus which constitutes its Commodity
Futures Trading Commission (“CFTC”) Disclosure Document. 
  
 3. Monthly Report. If trading for the Trust has commenced, the Authorized Participant has received a copy of its most recent monthly report as required by the CFTC. 
  
 4. Power of Attorney. In connection with the the
Authorized Participant’s acceptance of an interest in the Trust, the Authorized Participant does hereby irrevocably constitute and appoint the Managing Owner, and its successors and assigns, as its true and lawful Attorney-in-Fact, with full
power of substitution, in my name, place and stead, in the execution, acknowledgment, filing and publishing of Trust documents, including, but not limited to, the following: (i) Any certificates and other instruments, including but not limited to,
any applications for authority to do business and amendments thereto, which the Managing Owner deems appropriate to qualify or continue the Trust as a business or statutory trust in the jurisdictions in which the Trust may conduct business, so long
as such qualifications and continuations are in accordance with the terms of the Declaration of Trust and Trust Agreement of the Trust (the “Trust Agreement”) or any amendment hereto, or which may be required to be filed by the Trust or
the Shareholders under the laws of any jurisdiction; (ii) Any instrument which may be required to be filed by the Trust under the laws of any state or by any governmental agency, or which the Managing Owner deems advisable to file; and (iii) The
Trust Agreement and any documents which may be required to effect an amendment to the Trust Agreement approved under the terms of the Trust Agreement, and the continuation of the Trust, the admission of the signer of the Power of Attorney as a
Limited Owner or of others as additional or substituted Limited Owners, or the termination of the Trust, provided such continuation, admission or termination is in accordance with the terms of the Trust Agreement. The Power of Attorney granted
hereby shall be deemed to be coupled with an interest and shall be irrevocable and shall survive, and shall not be affected by, the Authorized Participant’s subsequent insolvency or dissolution or any delivery by the Authorized Participant of
an assignment of the whole or any portion of the Authorized Participant’s Units.

 PARTICIPANT AGREEMENT 
  
 ATTACHMENT A 
  
 DB COMMODITY INDEX TRACKING FUND PROCEDURES 
  
 CREATION AND REDEMPTION OF 
  
 DB COMMODITY INDEX TRACKING FUND SHARES 
  
 Scope of Procedures and Overview 
  
 These procedures (the “Procedures”) describe the processes by
which one or more Baskets of DB Commodity Index Tracking Fund shares (the “Shares”) issuable by DB Commodity Index Tracking Fund (the “Trust”), may be purchased or, once Shares have been issued, redeemed by an Authorized
Participant (a “Participant”) during the Continuous Offering Period. Shares may be created or redeemed only in blocks of 200,000 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                     2005, between
Wilmington Trust Company, as trustee of the Trust (the “Trustee”) DB Commodity 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 or the City of Wilmington are authorized or obligated by law or executive
order to close. 
  
 “Order Cut-Off Time” means 10:00 am,
New York time, on each Business Day. 
  
 Baskets are issued
pursuant to the Prospectus, which will be delivered by the Managing Owner to each Participant prior to 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 to Participants, in each case on
behalf of the Trust. Participants will be required to pay a nonrefundable per order transaction fee of $2,000 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 Baskets 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 Baskets. 
  
 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 the Order Cut-Off Time on a Business Day (such
day, “Purchase Order Subscription Date”) results in the issuance and delivery of Creation Baskets at noon, New York 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.

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.

Owner will then notify the Participant that the Order has been cancelled via telephone call. 
  
 3. 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 11:30 a.m. N.Y. time the Managing Owner returns to
the Participant a copy of the Purchase Order and Subscription Agreement submitted, marking it “Accepted.”

Capital Contribution. 
  
 5. 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. 
  
 6. At noon, New York 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. 
  
 7. 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.

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

  

	 	•	 	if the Trustee’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 
  
 1. By the Order Cut-off Time (10:00 a.m. N.Y. 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. 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. 

 
 2. 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 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 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. 
  
 3. If the Managing Owner
has received the Participant’s Redemption Order Form on time in accordance with the preceding timing rules, then by 11:30 a.m. N.Y. time the Managing Owner returns to the Participant a copy of the Redemption Order Form submitted, marking it
“Affirmed.” 
  
 4. As promptly as practicable following
the publication 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 Authorized Participant the amount of cash to be delivered in the Redemption
Distribution. 
  
 5. 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. 
  
 6. 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. 
  
 7. If by the Redemption Settlement Time the Managing Owner has not received from a redeeming Participant all Redemption Baskets comprising the Redemption
Order, the Trustee will (i) settle the Redemption Order to the extent of whole Redemption Baskets received from the Participant and (ii) keep the redeeming Participant’s Redemption Order open until noon, New York time, on the first Business Day
following the 

  

 3 

 
Redemption Settlement Date as to the balance of the Redemption Order (such balance, the “Suspended Redemption Order”). For each day (whether or not
a Business Day) the Redemption Order is held open, the Participant will be charged by the Trustee the greater of $300 or $30 times the number of Redemption Baskets included in the Suspended Redemption Order. 
  
 8. If the Redemption Basket(s) comprising the Suspended Redemption Order are
credited to Trustee’s account at the Depository by noon, New York 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 (5) above.

  
 9. If by such Redemption Settlement Time the Trustee 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. 
  

 4Form of Escrow Agreement

 EXHIBIT 10.1 
  
 ESCROW AGREEMENT 
  
 Escrow Agreement (this “Escrow Agreement”) dated as of the effective date (the “Effective Date”) set forth on
Schedule 1 attached hereto (“Schedule 1”) by and among DB Commodity Index Tracking Fund, a Delaware statutory trust (the “Issuer”), DB Commodity Services LLC, a Delaware limited liability
company (the “Managing Owner”), and                         , as escrow agent hereunder (the
“Escrow Agent”). Capitalized terms used but not defined in this Escrow Agreement shall have the meaning ascribed thereto in the prospectus of the Issuer, including all exhibits thereto, as the same may be amended from time to time
(the “Prospectus”). 
  
 WHEREAS, the Managing Owner serves
as the sole managing owner of the Issuer and has complete management authority over the Issuer; 
  
 WHEREAS, the Issuer has filed a registration statement on Form S-1 under the Securities Act of 1933, as amended, with the Securities and Exchange Commission, File No. 333-125325 (the “Registration
Statement”), relating to the subscription for and sale of “baskets” of shares of the Issuer, each basket consisting of 200,000 shares of the Issuer at a purchase price of twenty-five dollars ($25) per share, or an aggregate five
million dollars ($5,000,000) per basket (a “Basket”); and 
  
 WHEREAS, in compliance with Rule 15c2-4 under the Securities Exchange Act of 1934, as amended, the Issuer, the Managing Owner and the Depositor propose to establish an escrow fund to be held by the Escrow Agent until the expiration
of the initial offering period described in the Registration Statement. 
  
 NOW
THEREFORE, in consideration of the foregoing and of the mutual covenants hereinafter set forth, the parties hereto agree as follows: 
  
 1. Appointment. The Issuer and the Managing Owner hereby appoint the Escrow Agent as their escrow agent for the purposes set forth herein, and the Escrow Agent
hereby accepts such appointment under the terms and conditions set forth herein. 
  
 2. Escrow Fund. All funds received by the Issuer in connection with the sale of Baskets shall be deposited with the Escrow Agent (the “Escrow Deposit”). The Escrow Agent shall hold each Escrow Deposit and,
subject to the terms and conditions hereof, shall invest and reinvest each Escrow Deposit and the proceeds thereof (the “Escrow Fund”) as directed in Section 3. The Escrow Agent has provided the Managing Owner with the instructions
for making deposits set forth on Schedule 1 attached hereto. Deposits shall be credited to the appropriate account by the Escrow Agent as promptly as practicable but in no event more than three days after receipt by the Escrow Agent.

  
 3. Investment of Escrow Fund. The Escrow Fund shall be invested and
reinvested by the Escrow Agent only in U.S. Treasury obligations or any other investment specified by the Managing Owner that is consistent with the provisions of the federal securities laws. 
  
 4. Disposition and Termination. The Managing Owner agrees to notify the Escrow
Agent in writing of the termination date of the initial offering period described in the Registration Statement (the “Offering Closing Date”) and whether or not the Issuer received subscriptions in an amount equal to or greater than
the Minimum Subscription Amount. The term “Minimum Subscription Amount” means an aggregate amount of fifty million dollars ($50,000,000), or ten (10) Baskets. Upon receipt of such written notification the following procedure will
take place. 

	(i)	If the Issuer has received subscriptions for the Minimum Subscription Amount by the Offering Closing Date, the Escrow Fund will be promptly paid to or credited to the account of, or
otherwise transferred to the Issuer pursuant to written instructions from the Managing Owner on behalf of the Issuer. 

  

	(ii)	If the Issuer has not received subscriptions for the Minimum Subscription Amount by the Offering Closing Date, the Escrow Agent shall be provided with a list containing the amount
received from each subscriber for Baskets whose funds have been deposited with the Escrow Agent (with respect to each such subscriber the “Subscriber Investment Amount”) and the name, address and Taxpayer Identification Number
(“TIN”) of each such subscriber. The Escrow Agent must receive an originally executed W-9 or W-8 I.R.S. form for each subscriber who deposits funds into the Subscription Escrow Account. In addition, the Issuer shall calculate the
interest earned on each such Subscriber Investment Amount as of the Offering Closing Date and provide such information to the Escrow Agent. The aggregate of all Subscriber Investment Amounts and interest thereon shall be equal to the amount of the
Escrow Fund on the Offering Closing Date. The Escrow Agent shall distribute to each such subscriber the appropriate Subscriber Investment Amount and interest thereon pursuant to joint written instructions of the Managing Owner, on behalf of the
Issuer, as promptly as practicable but in no event more than seven (7) Business Days (as hereinafter defined) after the Offering Closing Date. 

  

	(iii)	The Managing Owner, on behalf of the Issuer, may reject any subscription for any reason or for no reason. Subscribers may, under certain circumstances, rescind their subscriptions.
If the Managing Owner rejects any subscription for which the Escrow Agent has already collected funds, or in the event that a subscriber rescinds its subscription in conformity with the requirements of the North American Securities Administrators
Association Inc. Guidelines for Registration of Commodity Pool Programs, which rescission has been approved by the Managing Owner and the Managing Owner has notified the Escrow Agent thereof, the Escrow Agent shall promptly issue a refund check or
wire transfer (if the Managing Owner provides the Escrow Agent with directions and wire instructions) to the subscriber, excluding any interest thereon, in the amount of the original subscription amount. 

  
 Upon delivery of each Escrow Fund to the Issuer or the applicable subscribers, as the case
may be, by the Escrow Agent, this Escrow Agreement shall terminate with respect to such Escrow Fund, subject to the provisions of Section 8. 
  
 5. Escrow Agent. The Escrow Agent undertakes to perform only such duties as are expressly set forth herein and no duties shall be implied. The Escrow Agent shall
have no liability under and no duty to inquire as to the provisions of any agreement other than this Escrow Agreement. The Escrow Agent may rely upon and shall not be liable for acting or refraining from acting upon any written notice, instruction
or request furnished to it hereunder and reasonably believed by it to be genuine and to have been signed or presented by the proper party or parties. The Escrow Agent shall be under no duty to inquire into or investigate the validity, accuracy or
content of any such document. The Escrow Agent shall have no duty to solicit any payments which may be due it or the Escrow Fund. The Escrow Agent shall not be liable for any action taken or omitted by it in good faith and without gross negligence
or willful misconduct. The Escrow Agent may execute any of its powers and perform any of its duties hereunder directly or through agents or attorneys (and shall be liable only for the careful selection of any such agent or attorney) and may consult
with counsel, accountants and other skilled persons carefully selected and retained by it. The Escrow Agent shall not be liable for anything done, suffered or omitted in good faith by it in accordance with the advice or opinion of any such counsel,
accountants or other skilled persons. In the event that the Escrow Agent shall be uncertain as to its duties or rights hereunder 
  

 2 

 or shall receive instructions, claims or demands from any party hereto which, in its opinion, conflict with any of the
provisions of this Escrow Agreement, it shall be entitled to refrain from taking any action and its sole obligation shall be to keep safely all property held in escrow until it shall be directed otherwise in writing by all of the other parties
hereto or by a final order or judgment of a court of competent jurisdiction. Anything in this Escrow Agreement to the contrary notwithstanding, in no event shall the Escrow Agent be liable for special, indirect or consequential loss or damage of any
kind whatsoever (including but not limited to lost profits), even if the Escrow Agent has been advised of the likelihood of such loss or damage and regardless of the form of action. 
  
 6. Succession. The Escrow Agent may resign and be discharged from its duties or obligations hereunder by giving thirty (30) days
advance notice in writing of such resignation to the other parties hereto specifying a date when such resignation shall take effect. The Escrow Agent shall have the right to withhold an amount equal to any amount due and owing to the Escrow Agent,
plus any costs and expenses the Escrow Agent shall reasonably believe may be incurred by the Escrow Agent in connection with the termination of the Escrow Agreement. Any corporation or association into which the Escrow Agent may be merged or
converted or with which it may be consolidated, or any corporation or association to which all or substantially all the escrow business of the Escrow Agent’s corporate trust line of business may be transferred, shall be the Escrow Agent under
this Escrow Agreement without further act. 
  
 7. Fees. The Managing
Owner and the Issuer agree jointly and severally to (i) pay the Escrow Agent upon execution of this Escrow Agreement and from time to time thereafter reasonable compensation for the services to be rendered hereunder, which unless otherwise agreed in
writing shall be as described in Schedule 1 attached hereto, and (ii) pay or reimburse the Escrow Agent upon request for all reasonable and appropriately evidenced expenses, disbursements and advances, including reasonable attorney’s
fees and expenses, incurred or made by it in connection with the preparation, execution, performance, delivery, modification and termination of this Escrow Agreement. 
  
 8. Indemnity. The Managing Owner and the Issuer shall jointly and severally indemnify, defend and save harmless the Escrow Agent and
its directors, officers, agents and employees (the “Indemnitees”) from all loss, liability or expense (including reasonable attorney’s fees and expenses) arising out of or in connection with (i) the Escrow Agent’s
execution and performance of this Escrow Agreement, except in the case of any Indemnitee, to the extent that such loss, liability or expense is due to the gross negligence or willful misconduct of such Indemnitee, or (ii) such Indemnitee’s
following any instructions or other directions reasonably believed by such Indemnitee to be from the Managing Owner or the Issuer, except to the extent that the Escrow Agent’s following any such instruction or direction is expressly forbidden
by the terms hereof. The parties hereto acknowledge that the foregoing indemnities shall survive the resignation or removal of the Escrow Agent or the termination of this Escrow Agreement. The parties hereby grant the Escrow Agent a lien on, right
of set-off against and security interest in each Escrow Fund for the payment of any claim for indemnification, compensation, expenses and amounts due hereunder. 
  

9. TINs. The Managing Owner and the Issuer each represent (severally and not jointly) that its correct TIN assigned by the Internal Revenue Service
(“IRS”) any other taxing authority is set forth in Schedule 1. Upon execution of this Escrow Agreement, the Managing Owner and the Issuer shall provide the Escrow Agent with a fully executed W-8 or W-9 ITS form, which shall
include the Managing Owner’s and the Issuer’s TIN. In the case of payments of interest or income to Subscribers directly, as mentioned in Section 4(ii), Subscriber must also remit their respective W-9 forms (or W-8 if foreign), to the
Escrow Agent to prevent any backup withholding tax. All interest or other income earned under the Escrow Agreement shall be allocated and/or paid as directed in a written direction of the Managing Owner and the Issuer and reported by the recipient
to the Internal Revenue Service or any other taxing 
  

 3 

 authority. Notwithstanding such written directions, Escrow Agent shall report and, as required withhold any taxes as it
determines may be required by any law or regulation in effect at the time of the distribution. In the absence of timely direction, all proceeds of the Escrow Fund shall be retained in the Escrow Fund and reinvested from time to time by the Escrow
Agent as provided in Section 3. In the event that any earnings remain undistributed at the end of any calendar year, Escrow Agent shall report to the Internal Revenue Service or such other authority such earnings as it deems appropriate or as
required by any applicable law or regulation or, to the extent consistent therewith, as directed in writing by the Issuer. In addition, the Escrow Agent shall withhold any taxes it deems appropriate and shall remit such taxes to the appropriate
authorities. 
  
 10. Notices. All communications hereunder shall be in
writing and shall be deemed to be duly given and received: 
  
 (i) upon delivery
if delivered personally or upon confirmed transmittal if by facsimile; 
  
 (ii) on
the next Business Day if sent by overnight courier; or 
  
 (iii) four (4) Business
Days after mailing if mailed by prepaid registered mail, return receipt requested, to the appropriate notice address set forth on Schedule 1 or at such other address as any party hereto may have furnished to the other parties in writing by
registered mail, return receipt requested. 
  
 In the event that the Escrow Agent,
in its sole discretion, shall determine that an emergency exists, the Escrow Agent may use such other means of communication as the Escrow Agent deems appropriate. “Business Day” shall mean any day other than a Saturday, Sunday or
any other day on which the Escrow Agent located at the notice address set forth on Schedule 1 is authorized or required by law or executive order to remain closed. 
  
 11. Security Procedures. In the event funds transfer instructions are given (other than in writing at the time of execution of this
Escrow Agreement, as indicated in Schedule 1 attached hereto), whether in writing, by telecopier or otherwise, the Escrow Agent is authorized to seek confirmation of such instructions by telephone call-back to the person or persons designated
on Schedule 2 attached hereto (“Schedule 2”), and the Escrow Agent may rely upon the confirmation of anyone purporting to be the person or persons so designated. The persons and telephone numbers for call-backs may be changed
only by notice in accordance with Section 10. If the Escrow Agent is unable to contact any of the authorized representatives identified in Schedule 2, the Escrow Agent is hereby authorized to seek confirmation of such instructions by
telephone call-back to any one or more of the executive officers of the Managing Owner (“Executive Officers”), which shall include the titles of [[Managing Director, Chief Executive Officer, Director or Treasurer]], as the
Escrow Agent may select. Such “Executive Officer” shall deliver to the Escrow Agent a fully executed Incumbency Certificate, and the Escrow Agent may rely upon the confirmation of anyone purporting to be any such officer. The Escrow Agent
and the beneficiary’s bank in any funds transfer may rely solely upon any account numbers or similar identifying numbers provided by the Managing Owner to identify (i) the beneficiary, (ii) the beneficiary’s bank, or (iii) an intermediary
bank. The Escrow Agent may apply any of the escrowed funds for any payment order it executes using any such identifying number, even when its use may result in a person other than the beneficiary being paid, or the transfer of funds to a bank other
than the beneficiary’s bank or an intermediary bank designated. The parties to this Escrow Agreement acknowledge that these security procedures are commercially reasonable.

 12. Miscellaneous. The provisions of this Escrow Agreement may be waived, altered, amended or supplemented, in
whole or in part, only by a writing signed by all of the parties hereto. Neither this Escrow Agreement nor any right or interest hereunder may be assigned in whole or in part by any party, except as provided in Section 6, without the prior consent
of the other parties. This Escrow Agreement shall be governed by and construed under the laws of the State of New York. Each party hereto irrevocably waives any objection on the grounds of venue, forum non-conveniens or any similar grounds and
irrevocably consents to service of process by mail or in any other manner permitted by applicable law and consents to the jurisdiction of the courts located in the State of New York. The parties further hereby waive any right to a trial by jury with
respect to any lawsuit or judicial proceeding arising or relating to this Escrow Agreement. No party to this Escrow Agreement is liable to any other party for losses due to, or if it is unable to perform its obligations under the terms of this
Escrow Agreement because of, acts of God, fire, floods, strikes, equipment or transmission failure, or other causes reasonably beyond its control. This Escrow Agreement may be executed in one or more counterparts, each of which shall be deemed an
original, but all of which together shall constitute one and the same instrument.
