The Administrative Trustee declares that it will hold all Trust Property, as Administrative Trustee, for the benefit of the Registered Owners for the purposes of, and subject to the terms and conditions set forth in, this Agreement. The Administrative Trustee and the Delaware Trustee are hereby authorized and directed to file the Certificate of Trust with the Delaware Secretary of State.

(b) The Trust shall not engage in any business or activities other than entering into the Investing Pool Agreement and holding Investing Pool Interests or activities incidental and necessary to carry out the duties and responsibilities with respect thereto and as set forth in, or contemplated by, this Agreement. Other than issuing Shares, the Trust shall not issue or sell any certificates or other obligations or otherwise incur, assume or guarantee any indebtedness for money borrowed.

Section 2.2 Legal Title. Legal title to all of the Trust Property shall be vested in the Trust as a separate legal entity; provided, however, that where applicable law in any jurisdiction requires any part of the Trust Property to be vested otherwise, the Administrative Trustee may cause legal title to the Trust Property or any portion thereof to be held by or in the name of the Administrative Trustee or any other Person (other than a Registered Owner or a Beneficial Owner) as nominee.

Section 2.3 Form of Certificates; Book-Entry System; Transferability of Shares. (a) The Certificates shall be substantially in the form set forth in Exhibit A hereto, with appropriate insertions, modifications and omissions, as hereinafter provided. No Shares shall be entitled to any benefits under this Agreement or be valid or obligatory for any purpose unless a Certificate evidencing those Shares has been executed by the manual or facsimile signature of a duly authorized signatory of the Administrative Trustee and, if a Registrar (other than the Administrative Trustee) for the Shares shall have been appointed, countersigned by the manual signature of a duly authorized officer of the Registrar. Certificates bearing the manual or facsimile signature of a duly authorized signatory of the Administrative Trustee and the manual signature of a duly authorized officer of the Registrar, if applicable, who was, at the time such Certificates were executed, a proper signatory of the Administrative Trustee or the Registrar, if applicable, shall bind the Administrative Trustee, notwithstanding that such signatory has ceased to hold such office prior to the delivery of such Certificates.

(b) The Certificates may be endorsed with or have incorporated in the text thereof such legends or recitals or modifications not inconsistent with the provisions of this Agreement as may be required by the Administrative Trustee or required to comply with any applicable law or regulations or with the rules and regulations of any securities exchange or automated quotation system upon which Shares may be listed or quoted or to conform with any usage with respect thereto, or to indicate any special limitations or restrictions to which the Shares evidenced by a particular Certificate are subject.

(c) The Sponsor and the Administrative Trustee will apply to DTC for acceptance of the Shares in its book-entry settlement system. Shares deposited with DTC shall be evidenced by one or more global Certificates, which shall be registered in the name of Cede & Co., as nominee for DTC, and shall bear the following legend:

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

(d) So long as the Shares are eligible for book-entry settlement with DTC and such settlement is available, unless otherwise required by law, notwithstanding the provisions of Sections 2.3(a) and (b), all Shares shall be evidenced by one or more global Certificates, the Registered Owner of which is DTC or a nominee of DTC, and (1) no Beneficial Owner will be entitled to receive a separate Certificate evidencing those Shares, (2) the interest of a Beneficial Owner in Shares represented by a global Certificate will be shown only on, and transfer of that

interest will be effected only through, records maintained by DTC or a DTC Participant or Indirect Participant through which the Beneficial Owner holds that interest and (3) the rights of a Beneficial Owner with respect to Shares represented by a global Certificate will be exercised only to the extent allowed by, and in compliance with, the arrangements in effect between such Beneficial Owner and DTC or the DTC Participant or Indirect Participant through which that Beneficial Owner holds an interest in Shares.

(e) If, at any time when Shares are evidenced by a global Certificate, DTC ceases to make its book-entry settlement system available for such Shares, the Sponsor and the Administrative Trustee may select a comparable depositary for the book-entry settlement of the Shares and cause new global Certificates to be issued and registered in the name of such successor depositary or its nominee. If the Sponsor and the Administrative Trustee determine that no such successor depositary is available, the Trust will terminate as set forth in Section 6.2(a)(vii) and, to the extent necessary in connection therewith, the Administrative Trustee shall execute and deliver separate Certificates evidencing Shares registered in the names of the Beneficial Owners thereof, with such additions, deletions and modifications to this Agreement and to the form of Certificate evidencing Shares as the Sponsor and the Administrative Trustee may agree.

(f) Title to a Certificate (and to the Shares evidenced thereby), when properly endorsed or accompanied by proper instruments of transfer, shall be transferable by delivery with the same effect as in the case of a certificated security under Article 8 of the Uniform Commercial Code of the State of Delaware; provided, however, that the Administrative Trustee, notwithstanding any notice to the contrary, may treat the Registered Owner of Shares as the absolute owner thereof for the purpose of determining the Person entitled to any distribution or to any notice provided for in this Agreement and for all other purposes.

Section 2.4 General. Subject to the terms of this Agreement, the Administrative Trustee shall have the power and authority, without the approval or action of any Registered Owner or Beneficial Owner, to issue and redeem Shares from time to time. The number of Shares authorized shall be unlimited. All Shares when so issued on the terms contemplated by this Agreement shall be fully paid and non-assessable. Every Registered Owner or Beneficial Owner, by virtue of having purchased or otherwise acquired a Share or a beneficial interest in a Share, shall be deemed to have expressly consented and agreed to be bound by the terms of this Agreement.

Section 2.5 Delivery of CERFs and Short-Term Securities. (a) After the Initial Delivery, subsequent issuances and Deliveries of Shares will take place only in integral numbers of Baskets and in compliance with the provisions of this Agreement, as supplemented by any procedures attached to an applicable Authorized Participant Agreement, to the extent those procedures are consistent with this Agreement.

(b) Authorized Participants wishing to acquire one or more Baskets must place an order with the Administrative Trustee (a “Purchase Order”), on any Business Day. Purchase Orders received by the Administrative Trustee on a Business Day prior to the Order Cutoff Time will have that Business Day as the Order Date. Purchase Orders received by the Administrative Trustee on a Business Day on or after the Order Cutoff Time, or on a day that is not a Business

Day, will have the next Business Day as the Order Date. As consideration for each Basket to be acquired pursuant to a Purchase Order, a Depositor must Deliver the Basket Amount on the Order Date of such corresponding Purchase Order.

(c) The Administrative Trustee shall determine the Basket Amount for each Business Day. After the Initial Delivery, the Basket Amount shall be an amount of CERFs and cash (or, as determined by the Administrative Trustee at the direction of the Sponsor, Short-Term Securities in lieu of cash) with a value equal to the Net Asset Value per Basket. The “Net Asset Value per Basket” is the result obtained by multiplying (x) the Net Asset Value per Share on the date on which the determination is being made by (y) the number of Shares that constitute a Basket on the date on which the determination is being made. The Sponsor intends to publish, or may designate other persons to publish, for each Business Day, the Basket Amount.

(d) All Delivered CERFs, Short-Term Securities and cash as part of a Purchase Order shall be contributed by the Administrative Trustee to the Investing Pool in return for an increase of the Trust’s Investing Pool Interests. The Investing Pool Interests and any other Trust Property will be held for the Trust at such place and in such manner as the Administrative Trustee shall determine.

Section 2.6 Delivery of Shares. Upon receipt by the Administrative Trustee of any Delivery in accordance with Section 2.5, together with a Purchase Order and the other required documents, if any, as specified above and a confirmation that the Basket Amount has been Delivered for each Basket, the Administrative Trustee, subject to the terms and conditions of this Agreement, shall Deliver to, or as directed by, the Depositor the number of Baskets issuable in respect of such Delivery as requested in the corresponding Purchase Order, but only upon payment to the Administrative Trustee of the fees and expenses of the Administrative Trustee as provided in Section 5.12(a) and of all taxes and governmental charges and fees payable in connection with such Delivery, the transfer of the CERFs, Short-Term Securities or cash and the issuance and Delivery of the Baskets.

Section 2.7 Registration and Registration of Transfer of Shares; Combination and Split-up of Certificates. (a) The Administrative Trustee shall keep or cause to be kept a register of Registered Owners and shall provide for the registration of Shares and the registration of transfers of Shares.

(b) The Administrative Trustee, subject to the terms and conditions of this Agreement, shall register transfers of ownership of Shares on its transfer books from time to time upon any Surrender of a Certificate evidencing such Shares by the Registered Owner in person or by a duly authorized attorney, properly endorsed or accompanied by proper instruments of transfer, and duly stamped as may be required by the laws of the State of New York and of the United States of America. Thereupon, the Administrative Trustee shall execute a new Certificate or Certificates evidencing such Shares, and deliver the same to or upon the order of the Person entitled thereto.

(c) The Administrative Trustee, subject to the terms and conditions of this Agreement, shall, upon Surrender of a Certificate or Certificates for the purposes of effecting a split-up or combination of that Certificate or Certificates, execute and deliver one or more new Certificates evidencing those Shares.

(d) The Administrative Trustee may, with the written approval of the Sponsor (which approval shall not be unreasonably withheld), appoint one or more co-transfer agents for the purpose of effecting registration of transfers of Shares and combinations and split-ups of Certificates at designated transfer offices on behalf of the Administrative Trustee. In carrying out its functions, a co-transfer agent may require evidence of authority and compliance with applicable laws and other requirements by Registered Owners or Persons entitled to Shares and will be entitled to protection and indemnity to the same extent as the Administrative Trustee.

Section 2.8 Redemption of Shares and Withdrawal of Trust Property. Upon Surrender by an Authorized Participant of any integral number of Baskets for the purpose of withdrawal of the amount of Trust Property represented thereby, and upon payment of the fee of the Administrative Trustee in connection with the Surrender of Shares as provided in Section 5.12(a) and payment of all taxes and charges payable in connection with such Surrender and withdrawal of Trust Property, and subject to the terms and conditions of this Agreement, including Section 2.9, such Baskets shall be redeemed by the Trust, and such Authorized Participant, as, or acting on authority of, the Registered Owner of those Shares will be entitled to Delivery, in accordance with the provisions of this Agreement, as supplemented by any procedures attached to an applicable Authorized Participant Agreement, to the extent those procedures are consistent with this Agreement, of the Basket Amounts corresponding to such Baskets on the applicable Order Date (determined as provided below). Authorized Participants wishing to so redeem one or more Baskets must place a written order with the Administrative Trustee (a “Redemption Order”). Redemption Orders received by the Administrative Trustee prior to the Order Cutoff Time on a Business Day will have that Business Day as the Order Date. Redemption Orders received by the Administrative Trustee on or after the Order Cutoff Time on a Business Day, or on a day that is not a Business Day, will have the next Business Day as the Order Date.

Section 2.9 Limitations on Issuance and Delivery, Registration of Transfer and Surrender of Shares. (a) As a condition precedent to the Delivery, registration of transfer, split-up, combination or Surrender of any Shares or withdrawal of any Trust Property, the Administrative Trustee or the Registrar may require payment from the Depositor or the Authorized Participant Surrendering the Shares of a sum sufficient to reimburse it for any tax or other governmental charge and any stock transfer or registration fee with respect thereto (including any such tax or charge and fee with respect to any securities being withdrawn) and payment of any applicable fees as herein provided, may require the production of proof satisfactory to it as to the identity and genuineness of any signature or other information that it deems to be necessary and may also require compliance with any regulations the Administrative Trustee may establish consistent with the provisions of this Agreement, including this Section 2.9.

(b) The issuance and Delivery of Shares against Delivery of CERFs, Short-Term Securities or cash, the registration of transfer of Shares or the Surrender of Shares for the purpose of withdrawal of Trust Property may be suspended generally, or refused with respect to particular requested Deliveries or Surrenders, during any period in which the transfer books of the Administrative Trustee are closed or if any such action is deemed to be necessary or advisable by the Administrative Trustee or the Sponsor for any reason at any time or from time to time.

Section 2.10 Lost Certificates, Etc. The Administrative Trustee shall execute and deliver a new Certificate of like tenor in exchange and substitution for a mutilated Certificate upon cancellation thereof, or in lieu of and in substitution for a destroyed, lost or stolen Certificate, if the Registered Owner thereof has (a) filed with the Administrative Trustee (i) a request for such execution and delivery before the Administrative Trustee has notice that the Shares evidenced by the Certificate have been acquired by a protected purchaser and (ii) a sufficient indemnity bond, and (b) satisfied any other reasonable requirements imposed by the Administrative Trustee.

Section 2.11 Cancellation and Destruction of Surrendered Certificates. All Certificates Surrendered to the Administrative Trustee shall be canceled by the Administrative Trustee. The Administrative Trustee is authorized to destroy Certificates so canceled.

Section 2.12 Splits and Reverse Splits of Shares. (a) If requested in writing by the Sponsor, the Administrative Trustee shall effect a split or reverse split of the Shares as of a record date set by the Administrative Trustee in accordance with procedures determined by the Administrative Trustee.

(b) The Administrative Trustee is not required to distribute any fraction of a Share in connection with a split or reverse split of the Shares. The Administrative Trustee may sell the aggregated fractions of Shares that would otherwise be distributed in a split or reverse split of the Shares or liquidate the amount of Trust Property that would be represented by those Shares and distribute the net proceeds of those Shares or that Trust Property to the Registered Owners entitled to such proceeds. The amount of Trust Property represented by each Share, the number of Shares comprising a Basket and the Basket Amount shall be adjusted as appropriate as of the open of business on the Business Day following the record date for a split or reverse split of the Shares.

(a) On each Business Day on which the Exchange is open for regular trading, as soon as practicable after the close of regular trading of the Shares on the Exchange, the Administrative Trustee shall determine the Net Asset Value of the Trust and the Net Asset Value per Share as of such closing time. The Administrative Trustee will value the Trust Property based on the net asset value of the Investing Pool as determined and transmitted in a report delivered to the Trust by or on behalf of the Manager on each such Business Day, unless the Administrative Trustee determines that such method of valuation is not appropriate as a basis for valuation of the Trust Property, in which case the Administrative Trustee will determine an alternative basis for valuation of the Trust Property. Neither the Administrative Trustee nor the Sponsor shall be liable to any Person for the determination that the most recently communicated net asset value of the Investing Pool is not appropriate as a basis for valuation of the Trust Property or for any determination as to the alternative basis for valuation; provided that such determination is made in good faith.

(b) Upon receipt by the Administrative Trustee of the Manager’s determination of the net asset value of the Investing Pool, the Administrative Trustee shall subtract all accrued expenses and other liabilities of the Trust from the total value of its Investing Pool Interests and all other assets of the Trust, in each case as of the time of calculation. The resulting figure is the “Net Asset Value of the Trust.” The Administrative Trustee shall divide the Net Asset Value of the Trust by the number of Shares outstanding as of the time of the calculation, which figure is the “Net Asset Value per Share.” All fees, expenses and other liabilities of the Trust that are or will be incurred or accrued through the close of business on a Business Day shall be included in the calculations required by this Section 4.1(b) for that Business Day. Shares deliverable under a Purchase Order shall be considered to be outstanding for purposes of the calculations required by this Section 4.1(b) beginning on the Order Date. Shares deliverable under a Redemption Order shall not be considered to be outstanding for purposes of the calculations required by this Section 4.1(b) on and after the Order Date.

Section 4.2 Responsibility of the Administrative Trustee for Determinations. The Sponsor shall have no responsibility for the accuracy of any determination of any amount made

by the Administrative Trustee. The determinations made by the Administrative Trustee under this Agreement shall be made in good faith upon the basis of, and the Administrative Trustee shall not be liable for any errors contained in, information reasonably available to it. The Administrative Trustee shall be under no liability to the Sponsor, or to the Depositors, the Registered Owners or the Beneficial Owners, for errors in judgment; provided, however, that this provision shall not protect the Administrative Trustee against any liability to which it would otherwise be subject by reason of negligence or bad faith in the performance of its duties.

Section 4.3 Cash Distributions. Whenever the Administrative Trustee distributes any cash, the Administrative Trustee shall distribute the amount available for distribution to the Registered Owners entitled thereto, in proportion to the number of Shares held by them respectively. The Administrative Trustee shall distribute only such amount, however, as can be distributed without attributing to any Registered Owner a fraction of one cent. Any such fractional amounts shall be rounded down to the nearest whole cent.

Section 4.4 Other Distributions. Whenever the Administrative Trustee receives any property in respect of Trust Property other than cash (including any claim that accrues in favor of the Trust on account of any loss of Investing Pool Interests or other Trust Property), the Administrative Trustee shall cause the securities or other property received by it to be distributed to the Registered Owners entitled thereto, in proportion to the number of Shares held by them respectively, after deduction or upon payment of the expenses of the Administrative Trustee, in any manner that the Administrative Trustee may deem to be lawful, equitable and feasible for accomplishing such distribution; provided, however, that if in the opinion of the Administrative Trustee such distribution cannot be made proportionately among the Registered Owners entitled thereto, or if for any other reason (including any requirement that the Administrative Trustee withhold an amount on account of taxes or other governmental charges or that securities must be registered under the Securities Act in order to be distributed to the Registered Owners) the Administrative Trustee deems such distribution not to be lawful and feasible, the Administrative Trustee shall adopt such method as it deems to be lawful, equitable and feasible for the purpose of effecting such distribution, after deduction or upon payment of the expenses of the Administrative Trustee, including the public or private sale of the securities or property thus received, or any part thereof, and the net proceeds of any such sale shall be distributed by the Administrative Trustee to the Registered Owners entitled thereto as in the case of a distribution received in cash.

Section 4.5 Withholding Tax. The Trust shall comply with all applicable withholding and backup withholding tax requirements. The Trust shall request, and the Beneficial Owners shall provide to the Trust, and direct any broker or nominee through which the Beneficial Owner owns the Shares to provide to the Trust, such forms or other documentation as are necessary to establish an exemption from withholding tax and backup withholding with respect to each Beneficial Owner, and any representations, forms and documents as shall reasonably be requested by the Trust to assist it in determining the extent of, and in fulfilling, its withholding and backup withholding tax obligations. The Administrative Trustee shall file any required forms with applicable jurisdictions and, unless an exemption from withholding and backup withholding tax is properly established by a Beneficial Owner, shall remit amounts withheld with respect to the Beneficial Owner to the applicable tax authorities. To the extent that the Administrative Trustee reasonably believes that it is required to withhold and pay over any

amounts (including taxes, interest, penalties, assessments or additions to tax) to any tax authority with respect to distributions or allocations to any Beneficial Owner, and the Administrative Trustee does withhold such amounts, the amounts withheld shall be treated as a distribution of cash to the Beneficial Owner, in the amount of the withholding and shall thereby reduce the amount of cash or other Trust Property otherwise distributable to such Beneficial Owner. If an amount required to be withheld was not withheld, the Trust may reduce subsequent distributions by the amount of such required withholding. The consent of the Beneficial Owners shall not be required for any such withholding. In the event of any claimed over-withholding, Beneficial Owners shall be limited to an action against the applicable jurisdiction.

Section 4.6 Fixing of Record Date. Whenever any distribution will be made, or whenever the Administrative Trustee receives notice of any solicitation of proxies or consents from Registered Owners, or whenever for any reason there is a split, reverse split or other change in the outstanding Shares, or whenever the Administrative Trustee shall find it necessary or convenient in respect of any matter, the Administrative Trustee, in consultation with the Sponsor, shall fix a record date for the determination of the Registered Owners who shall be (a) entitled to receive such distribution or the net proceeds of the sale thereof, (b) entitled to give such proxies or consents in respect of any such solicitation or (c) entitled to act in respect of any other matter for which the record date was set.

Section 4.7 Payment of Expenses; Sales of Trust Property. (a) The following charges are or may be accrued and paid by the Trust:

(1) any expenses of the Trust not assumed by the Sponsor pursuant to Section 5.7(f);

(2) any taxes and other governmental charges that may fall on the Trust or the Trust Property;

(3) any expenses of any extraordinary services performed by the Administrative Trustee or the Sponsor on behalf of the Trust or expenses of any action taken by the Administrative Trustee or the Sponsor to protect the Trust or the interests of Registered Owners or the Beneficial Owners; and

(4) any indemnification of the Sponsor as provided in Section 5.11(d).

(b) The Administrative Trustee shall, when directed by the Sponsor, sell or liquidate Trust Property in such quantity and at such times as may be necessary to permit payment of expenses under this Agreement. Neither the Administrative Trustee nor the Sponsor shall have any liability for loss or depreciation resulting from sales of Investing Pool Interests so made. The Administrative Trustee shall not be liable or responsible in any way for depreciation or loss incurred by reason of any sale made pursuant to the Sponsor’s direction or otherwise in accordance with this Section 4.7.

(c) If, at any time and from time to time, the Administrative Trustee determines that the amount of cash included in the Trust Property exceeds the reasonably anticipated expenses of the Trust, the Administrative Trustee may, at the direction of the Sponsor, distribute the excess

cash to the Registered Owners under Section 4.3 or contribute it to the Investing Pool for an increase in the Trust’s Investing Pool Interests. The Trust shall have no obligation to make any such distribution, or any other periodic distributions to the Registered Owners.

Section 4.8 Statements and Reports. (a) After the end of each fiscal year and within the time period required by applicable laws, rules and regulations, at the Sponsor’s expense, the Administrative Trustee shall send to the Registered Owners at the end of such fiscal year an annual report of the Trust containing financial statements that will be prepared by the Administrative Trustee and audited by independent accountants designated by the Sponsor and such other information as may be required by such laws, rules and regulations or otherwise, or which the Sponsor determines shall be included. The Administrative Trustee may distribute the annual report by any means acceptable to such Registered Owners.

(b) The Administrative Trustee shall provide the Sponsor with such certifications, supporting documents and other evidence regarding the internal control over financial reporting established and maintained by the Trust, and used by the Administrative Trustee in connection with its preparation of the financial statements of the Trust, as may be reasonably necessary in order to enable the Sponsor to prepare and file or furnish to the SEC any certifications regarding such matters that may be required to be included with the Trust’s periodic reports under the Exchange Act.

Section 4.9 Further Provisions for Sales of Trust Property. In addition to selling Trust Property in accordance with Section 4.7, the Administrative Trustee shall sell Trust Property whenever either or both of the following conditions exist:

(1) the Sponsor has notified the Administrative Trustee that such sale is required by applicable law or regulation; or

(2) this Agreement has been terminated and the Trust Property is to be liquidated in accordance with Section 6.2.

The Administrative Trustee and the Sponsor shall not be liable or responsible in any way for depreciation or loss incurred by reason of any sale made pursuant to this Section 4.9.

Section 4.10 Counsel. The Sponsor may, from time to time, employ counsel to act on behalf of the Trust and perform any legal services in connection with the Trust Property and the Trust, including any legal matters relating to the possible disposition or acquisition of any Investing Pool Interests or the Delivery of any CERFs or Short-Term Securities. The fees and expenses of such counsel shall be paid by the Sponsor; provided, however, that the Sponsor shall not be responsible for the payment of any such fees and expenses in excess of $100,000 annually.

Section 4.11 Tax Matters. (a) The parties hereto and, by its acceptance or acquisition of a Share or a beneficial interest therein, the Beneficial Owner of such Share, and the broker or nominee through which the Beneficial Owner owns its Share, intend and agree to treat the Trust as a grantor trust for United States federal, state and local tax purposes, and to treat the Shares (including, but not limited to, all payments and proceeds with respect to such Shares) as beneficial ownership interests in their respective proportionate share of the Trust Property (and

payments and proceeds therefrom, respectively) for United States federal, state and local tax purposes and agree to use reasonable efforts to notify the Administrative Trustee and the Sponsor promptly upon a receipt of any notice from any taxing authority having jurisdiction over such holders of Shares with respect to the treatment of the Shares as anything other than interests in a grantor trust or in any other way inconsistent with the treatment set forth herein. Allocations of income, gain, expense, loss, deduction and credit made by the Investing Pool with respect to each Beneficial Owner’s proportionate share of the Trust Property shall be treated by the parties hereto, and by the Beneficial Owner as an allocation of the corresponding item of Trust income, gain, expense, loss, deduction and credit to such Beneficial Owner. Accordingly, the Beneficial Owner shall comply with any obligations imposed on Members with respect to Capital Accounts or allocations of taxable income or expense in the Investing Pool Agreement as if such obligations were imposed on the Beneficial Owner. If an election is made pursuant to Section 754 of the Code by the Investing Pool, the Administrative Trustee shall make, on behalf of the Trust, a protective Section 754 election for each taxable year. To the extent that any of the parties hereto or any Beneficial Owner is required to report any item of income, gain, loss, deduction or credit relating to the Trust for United States federal, state and local tax purposes, that person shall report such item in a manner consistent with the characterization intended by this Section 4.11 and the treatment of such item by the Trust and the Investing Pool and shall not take any contrary position on any tax return or report or take any other action that is inconsistent with such characterization or treatment, except as required by law. The provisions of this Agreement shall be interpreted to further this intention and agreement of the parties.

(b) The Administrative Trustee shall timely prepare, sign and file (or cause to be prepared, signed and filed) all income, franchise, information and other tax forms, returns, statements and reports required to be filed by or in respect of the Trust as a grantor trust in each taxable year of the Trust, and shall timely pay (or cause to be paid) any tax, assessment or other governmental charge owing with respect to the Trust out of Trust Property. The Administrative Trustee shall promptly notify the Sponsor if it becomes aware that any tax, assessment or other governmental charge is due or claimed to be due with respect to the Trust. The Administrative Trustee shall provide to each Beneficial Owner, and the broker or nominee through which a Beneficial Owner owns its Share, appropriate tax information adequate to enable each Beneficial Owner for whose benefit the broker or nominee holds its Share to complete and file its U.S. federal income tax return (which information shall be consistent with any information provided to the Trust by the Investing Pool), as soon as practicable following each fiscal year but generally not later than March 15. The Trustee shall provide the Sponsor with a copy of such documents promptly after such filing or furnishing. If not already obtained, the Administrative Trustee shall obtain a taxpayer identification number for the Trust. The Trust hereby indemnifies, to the full extent permitted by law, the Administrative Trustee from and against any damages or losses (including attorneys’ fees) arising out of or incurred in connection with any action taken or omitted to be taken by it in carrying out its responsibilities under this Section 4.11, to the extent that such action taken or omitted to be taken does not constitute fraud, negligence or misconduct.

(c) The Trust will not make an election to be treated as an association taxable as a corporation for U.S. federal income tax purposes pursuant to Treasury Regulation Section 301.7701-3, or any successor provision thereof, or a similar election under any analogous provision for purposes of state or local law, and, to the extent necessary, the Trust or a Beneficial

Owner (as appropriate) will make any election necessary to obtain treatment not as an association taxable as a corporation. Nothing in this Agreement, any agreement with a Custodian, or otherwise, shall be construed to give the Administrative Trustee or any other person the power to vary the investment of the Beneficial Owners within the meaning of Section 301.7701-4(c) under the Code or any similar or successor provision of the regulations under the Code, nor shall the Sponsor give the Administrative Trustee any direction that would vary the investment of the Beneficial Owners. However, the Administrative Trustee shall not be liable to any Person for any failure of the Trust to qualify as a grantor trust under the Code or any comparable provision of the laws of any State or other jurisdiction where that treatment is sought, except that this sentence shall not limit the Administrative Trustee’s responsibility for the administration of the Trust in accordance with this Agreement.

(d) The parties hereto and, by its acceptance or acquisition of a Share or a beneficial interest therein, a Beneficial Owner and the broker or nominee through which the Beneficial Owner owns its Share (i) agree to furnish the Sponsor and the Administrative Trustee with such representations, forms, documents or information as may be necessary to enable the Trust and the Investing Pool to comply with their U.S. federal income tax reporting obligations in respect of such Share and to allow the Trust and the Investing Pool to make the basis adjustments permitted by Section 754 of the Code, including information regarding such Beneficial Owner’s secondary market transactions in Shares, as well as creations or redemptions of Shares and including information that would be required by Treasury Regulations Section 1.6031(c)-1T and any successor thereto if that Section applied to the holding of Shares and (ii) direct brokers and nominees to report to the Administrative Trustee the Beneficial Owner’s name and address and such other information as may be reasonably requested by the Administrative Trustee for purposes of complying with the Trust’s or the Investing Pool’s U.S. federal income tax reporting obligations or as necessary to allow the Trust or the Investing Pool to make the basis adjustments permitted by Section 754 of the Code, including information that would be required by Treasury Regulations Section 1.6031(c)-1T and any successor thereto if that Section applied to the holding of Shares.

(e) By its acceptance of a beneficial interest in a Share, a Beneficial Owner waives all confidentiality rights, including all confidentiality rights provided by Section 3406(f) of the Code and Treasury Regulations Section 31.3406(f)-1, with respect to any representations, forms, documents or information, and any information contained in such representations, forms or documents, that the Beneficial Owner provides, or has previously provided, to any broker or nominee through which it owns its Shares, to the extent such representations, forms, documents or information may be necessary to (i) assist the Trust in complying with its withholding tax and backup withholding tax obligations pursuant to Section 4.5 of this Agreement or (ii) enable the Trust and the Investing Pool to comply with their U.S. federal income tax reporting obligations, or to allow the Trust and the Investing Pool to make the basis adjustments under Section 754 of the Code with respect to such Share, pursuant to Section 4.11(d) of this Agreement. Furthermore, the parties hereto, and by its acceptance of a beneficial interest in a Share, a Beneficial Owner, acknowledge and agree that any broker or nominee through which a Beneficial Owner holds its Shares shall be a third party beneficiary to this Agreement for the purposes set forth in Sections 4.5, 4.11(d) and this 4.11(e) of this Agreement.

(f) The Administrative Trustee shall maintain all books, records and supporting documents that are necessary to comply with any and all aspects of its duties under this Agreement.

(g) By its acceptance or acquisition of a beneficial interest, the Beneficial Owner of a Share consents and agrees to the provisions of Sections 3.9 and 6.6 of the Investing Pool Agreement.

Without limiting the foregoing, the Sponsor shall have the authority to execute and deliver the Investing Pool Agreement and the Distribution Agreement on behalf of the Trust and the Trust is authorized and shall have the power and authority to enter into such agreements and perform its obligations thereunder.

Section 5.4 Prevention or Delay in Performance by the Sponsor or the Administrative Trustee. Neither the Sponsor nor the Administrative Trustee nor any of their respective directors, employees, agents or affiliates shall incur any liability to any Registered Owner, Beneficial Owner, Authorized Participant or Depositor if, by reason of any provision of any present or future law or regulation of the United States or any other country, or of any governmental or regulatory authority or stock exchange, or by reason of any act of God or war or terrorism or other circumstances beyond its control, the Sponsor or the Administrative Trustee is prevented or forbidden from, or would be subject to any civil or criminal penalty on account of, or is delayed in, doing or performing any act or thing that, by the terms of this Agreement, it is provided shall be done or performed, and, accordingly, the Sponsor or the Administrative Trustee does not do that thing or does that thing at a later time than would otherwise be required.

Section 5.5 Liability of Covered Persons. A Covered Person shall have no liability to the Trust or to any Registered Owner, Beneficial Owner, Authorized Participant, Depositor or to any other Covered Person for any loss suffered by the Trust that arises out of any action or inaction of such Covered Person if such Covered Person, in good faith, determined that such course of conduct was in the best interest of the Trust and such course of conduct did not constitute negligence (or, in the case of the Delaware Trustee, gross negligence) or bad faith of such Covered Person. Subject to the foregoing, no Covered Person shall be personally liable for the return or repayment of all or any portion of the capital or profits of any Registered Owner, Beneficial Owner, Authorized Participant, Depositor or assignee thereof, it being expressly agreed that any such return of capital or profits made pursuant to this Agreement shall be made solely from the assets of the Trust without any rights of contribution from any Covered Person. A Covered Person shall not be liable for the conduct or misconduct of any delegatee selected by the Administrative Trustee pursuant to Section 5.8 of this Agreement; provided, however, that in the case of the Administrative Trustee the foregoing shall only apply if the Administrative Trustee made such selection with reasonable care.

The provisions of this Agreement, to the extent that they restrict the duties and liabilities of the Administrative Trustee or the Sponsor otherwise existing at law or in equity are agreed by the parties hereto to replace such other duties and liabilities of the Administrative Trustee and the Sponsor.

(b) Unless otherwise expressly provided herein:

(i) whenever a conflict of interest exists or arises between the Administrative Trustee, the Sponsor or any of their respective Affiliates, on the one hand, and the Trust or any Registered Owner, Beneficial Owner, Authorized Participant, Depositor or other Person, on the other hand; or

(ii) whenever this Agreement or any other agreement contemplated herein provides that the Administrative Trustee or the Sponsor shall act in a manner that is, or provides terms that are, fair and reasonable to the Trust, any Registered Owner, Beneficial Owner, Authorized Participant, Depositor or other Person,

the Administrative Trustee and the Sponsor, respectively, shall resolve such conflict of interest, take such action or provide such terms, considering in each case the relative interest of each party (including its own interest) to such conflict, agreement, transaction or situation and the benefits and burdens relating to such interests, any customary or accepted industry practices, and any applicable generally accepted accounting practices or principles. In the absence of bad faith by the Administrative Trustee or the Sponsor, the resolution, action or terms so made, taken or provided by the Administrative Trustee or the Sponsor shall not constitute a breach of this Agreement or any other agreement contemplated herein or of any duty or obligation of the Administrative Trustee or the Sponsor at law or in equity or otherwise.

(c) Notwithstanding any other provision of this Agreement or of applicable law, whenever in this Agreement the Administrative Trustee or the Sponsor is permitted or required to make a decision

(d) The Administrative Trustee, the Sponsor and any of their respective Affiliates may engage in or possess an interest in other profit-seeking or business ventures of any nature or description, independently or with others, whether or not such ventures are competitive with the Trust, and the doctrine of corporate opportunity, or any analogous doctrine, shall not apply to the Administrative Trustee or the Sponsor. If the Administrative Trustee or the Sponsor acquires knowledge of a potential transaction, agreement, arrangement or other matter that may be an opportunity for the Trust, it shall have no duty to communicate or offer such opportunity to the Trust, and the Administrative Trustee and the Sponsor shall not be liable to the Trust or to the

Registered Owners, the Beneficial Owners, the Authorized Participants or the Depositors for breach of any fiduciary or other duty by reason of the fact that the Administrative Trustee or the Sponsor pursues or acquires for, or directs such opportunity to, another Person or does not communicate such opportunity or information to the Trust. Neither the Trust nor any Registered Owner, Beneficial Owner, Authorized Participant or Depositor shall have any rights or obligations by virtue of this Agreement or the trust relationship created hereby in or to such independent ventures or the income or profits or losses derived therefrom, and the pursuit of such ventures, even if competitive with the activities of the Trust, shall not be deemed to be wrongful or improper. Except to the extent expressly provided herein, the Administrative Trustee and the Sponsor may engage or be interested in any financial or other transaction with the Trust, the Registered Owners, the Beneficial Owners, the Authorized Participants, the Depositors or any Affiliate of the Trust or the Beneficial Owners.

Section 5.7 Obligations of the Sponsor and the Administrative Trustee. (a) Neither the Sponsor nor the Administrative Trustee assumes any obligation nor shall either of them be subject to any liability under this Agreement to any Registered Owner or Beneficial Owner, Authorized Participant or Depositor (including liability with respect to the worth of the Trust Property), except that each of them agrees to perform its obligations specifically set forth in this Agreement without negligence or bad faith.

(b) Neither the Sponsor nor the Administrative Trustee shall be under any obligation to prosecute any action, suit or other proceeding in respect of any Trust Property or in respect of the Shares on behalf of a Registered Owner, Beneficial Owner, Authorized Participant, Depositor or other Person.

The Administrative Trustee may at any time delegate all or a portion of its duties and obligations under this Agreement to another entity, including the trust administrator, without the consent of the Sponsor, the Delaware Trustee, any Registered Owner and any Beneficial Owner. The Administrative Trustee may terminate such other entity at any time and is not required to appoint a replacement therefor.

Section 5.9 Resignation or Removal of the Administrative Trustee; Appointment of Successor Administrative Trustee. (a) The Administrative Trustee may at any time resign as Administrative Trustee hereunder by written notice of its election so to do, delivered to the Sponsor, and such resignation shall take effect upon the appointment of a successor Administrative Trustee and its acceptance of such appointment as hereinafter provided.

(b) The Sponsor may remove the Administrative Trustee in its discretion by written notice delivered to the Administrative Trustee in the manner provided in Section 7.4 at any time after the first anniversary of the date of this Agreement. If at any time the Administrative Trustee ceases to be a Qualified Bank or is in material breach of its obligations under this Agreement and the Administrative Trustee fails to cure such breach within thirty (30) days after receipt by the Administrative Trustee of written notice from the Sponsor, or Registered Owners acting on behalf of at least 25% of the outstanding Shares, specifying such default and requiring the Administrative Trustee to cure such default, the Sponsor may remove the Administrative Trustee by written notice delivered to the Administrative Trustee in the manner provided in Section 7.4, and such removal shall take effect upon the appointment of a successor Administrative Trustee and its acceptance of such appointment as hereinafter provided.

(c) If the Administrative Trustee acting hereunder resigns or is removed, the Sponsor shall use its reasonable efforts to appoint a successor Administrative Trustee, which shall be a Qualified Bank. Every successor Administrative Trustee shall execute and deliver to its predecessor and to the Sponsor an instrument in writing accepting its appointment hereunder, and thereupon such successor Administrative Trustee, without any further act or deed, shall become fully vested with all the rights, powers, duties and obligations of its predecessor; but such predecessor, nevertheless, upon payment of all sums due to it and on the written request of the Sponsor, shall execute and deliver an instrument transferring to such successor all rights and powers of such predecessor hereunder, shall duly assign, transfer and deliver all right, title and interest in the Trust Property to such successor and shall deliver to such successor a list of the Registered Owners of all outstanding Shares. The Sponsor or any such successor Administrative Trustee shall promptly mail notice of the appointment of such successor Administrative Trustee to the Registered Owners.

(d) Any corporation into which the Administrative Trustee may be merged, consolidated or converted in a transaction in which the Administrative Trustee is not the surviving corporation shall be the successor of the Administrative Trustee without the execution or filing of any document or any further act. During the 90-day period following the effectiveness of a merger, consolidation or conversion described in the immediately preceding

sentence, the Sponsor may, by written notice to the Administrative Trustee, remove the Administrative Trustee and designate a successor Administrative Trustee in compliance with the provisions of Section 5.9(c).

Section 5.10 Custodians. The Administrative Trustee may at any time appoint one or more custodians (each, a “Custodian”) to hold assets of the Trust, without the consent of any Registered Owner and any Beneficial Owner. The Administrative Trustee may terminate any such Custodian at any time and is not required to appoint a replacement therefor.

Section 5.11 Indemnification. (a) The Sponsor shall indemnify the Administrative Trustee, its directors, employees, delegates and agents (the “Administrative Trustee Indemnified Persons”) against, and hold each of them harmless from, any loss, liability, cost, expense or judgment (including the reasonable fees and expenses of counsel) (collectively, “Indemnified Amounts”) that is incurred by any of them and that arises out of or is related to (i) any offer or sale by the Trust of Baskets under this Agreement, (ii) acts performed or omitted pursuant to the provisions of this Agreement, as the same may be amended, modified or supplemented from time to time, (A) by an Administrative Trustee Indemnified Person or (B) by the Sponsor or (iii) any filings with or submissions to the SEC in connection with or with respect to the Shares (which, by way of illustration and not by way of limitation, include any registration statement and any amendments or supplements thereto filed with the SEC or any periodic reports or updates that may be filed under the Exchange Act or any failure to make any filings with or submissions to the SEC that are required to be made in connection with or with respect to the Shares), except that the Sponsor shall not have any obligations under this Section 5.11(a) to pay any Indemnified Amounts incurred as a result of and attributable to (x) the negligence or bad faith of, or material breach of the terms of this Agreement by, the Administrative Trustee, (y) information furnished in writing by the Administrative Trustee to the Sponsor expressly for use in the registration statement, or any amendment thereto, filed with the SEC relating to the Shares that is not materially altered by the Sponsor or (z) any misrepresentations or omissions made by a Depositor (other than the Sponsor) in connection with such Depositor’s offer and sale of Shares.

(b) The Administrative Trustee shall indemnify the Sponsor, its directors, employees and agents against, and hold each of them harmless from, any Indemnified Amounts (i) caused by the negligence or bad faith of the Administrative Trustee or (ii) arising out of any information furnished in writing to the Sponsor by the Administrative Trustee expressly for use in the registration statement, or any amendment thereto or periodic report, filed with the SEC relating to the Shares that is not materially altered by the Sponsor.

(c) If the indemnification provided for in Section 5.11(a) or (b) is unavailable or insufficient to hold harmless the indemnified party under Section 5.11(a) or (b) above, then the indemnifying party shall contribute to the Indemnified Amounts referred to in Section 5.11(a) or (b) above (i) in such proportion as is appropriate to reflect the relative benefits received by the Sponsor on the one hand and the Administrative Trustee on the other hand from the offering of the Shares which are the subject of the action 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 Sponsor on the one hand and the Administrative Trustee on the other hand in connection with the action, statement or omission that resulted in such Indemnified Amount, as well as any other relevant

equitable considerations. The relative fault shall be determined by reference to, among other things, whether any untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact from which the action arises relates to information supplied by the Sponsor or the Administrative Trustee and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission or the act or omission from which the action arises. The amount of Indemnified Amounts referred to in the first sentence of this Section 5.11(c) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim that is the subject of this Section 5.11.

(d) The Sponsor and its shareholders, directors, officers, employees, affiliates (as such term is defined under the Securities Act) and subsidiaries (each, a “Sponsor Indemnified Party”) shall be indemnified from the Trust and held harmless against any loss, liability or expense arising out of or in connection with the performance of its obligations under this Agreement or any actions taken in accordance with the provisions of this Agreement and incurred without (1) negligence, bad faith, willful misconduct or willful malfeasance on the part of such Sponsor Indemnified Party or (2) reckless disregard on the part of such Sponsor Indemnified Party of its obligations and duties under this Agreement. Such indemnity shall include payment from the Trust of the costs and expenses incurred by such Sponsor Indemnified Party in defending itself against any claim or liability in its capacity as Sponsor. Any amounts payable to a Sponsor Indemnified Party under this Section 5.11(d) may be payable in advance or shall be secured by a lien on the Trust. The Sponsor may, in its discretion, undertake any action that it may deem to be necessary or desirable in respect of this Agreement and the rights and duties of the parties hereto and the interests of the Registered Owners and, in such event, the legal expenses and costs of any such actions shall be expenses and costs of the Trust, and the Sponsor shall be entitled to be reimbursed therefor by the Trust.

(e) If an action, proceeding (including, but not limited to, any governmental investigation), claim or dispute (collectively, a “Proceeding”) in respect of which indemnity may be sought by either party is brought or asserted against the other party, the party seeking indemnification (the “Indemnitee”) shall promptly (and in no event more than seven (7) days after receipt of notice of such Proceeding) notify the party obligated to provide such indemnification (the “Indemnitor”) of such Proceeding. The failure of the Indemnitee to so notify the Indemnitor shall not impair the Indemnitee’s ability to seek indemnification from the Indemnitor (but only for costs, expenses and liabilities incurred after such notice) unless such failure adversely affects the Indemnitor’s ability to adequately oppose or defend such Proceeding. Upon receipt of such notice from the Indemnitee, the Indemnitor shall be entitled to participate in such Proceeding and, to the extent that it shall so desire and provided no conflict of interest exists as specified in clause (i) below and there are no other defenses available to Indemnitee as specified in clause (iii) below, to assume the defense thereof with counsel reasonably satisfactory to the Indemnitee (in which case all attorney’s fees and expenses shall be borne by the Indemnitor, and the Indemnitor shall in good faith defend the Indemnitee). The Indemnitee shall have the right to employ separate counsel in any such Proceeding and to participate in the defense thereof, but, in such case, no fees and expenses of such counsel shall be borne by the Indemnitor unless such fees and expenses are otherwise required to be indemnified under Section 5.11(a), (b) or (d), as applicable, and (i) there is such a conflict of interest between the Indemnitor and the Indemnitee as would preclude, in compliance with the ethical rules in

effect in the jurisdiction in which the Proceeding was brought, one lawyer from representing both parties simultaneously, (ii) the Indemnitor fails, within the earlier of (x) twenty (20) days following receipt of notice of the Proceeding from the Indemnitee or (y) seven (7) days prior to the date the first response or appearance is required to be made in such Proceeding, to assume the defense of such Proceeding with counsel reasonably satisfactory to the Indemnitee or (iii) there are legal defenses available to Indemnitee that are different from or are in addition to those available to the Indemnitor. No compromise or settlement of such Proceeding may be effected by either party without the other party’s consent unless (m) there is no finding or admission of any violation of law and no effect on any other claims that may be made against such other party and (n) the sole relief provided is monetary damages that are paid in full by the party seeking the settlement. Neither party shall have any liability with respect to any compromise or settlement effected without its consent, which shall not be unreasonably withheld. The Indemnitor shall have no obligation to indemnify and hold harmless the Indemnitee from any loss, expense or liability incurred by the Indemnitee as a result of a default judgment entered against the Indemnitee unless such judgment was entered after the Indemnitor agreed, in writing, to assume the defense of such Proceeding.

Section 5.12 Charges of Administrative Trustee. (a) Each Depositor and each Person Surrendering Baskets for the purpose of withdrawing Trust Property shall pay to the Administrative Trustee a transaction fee of $[•] per Basket multiplied by the number of CERFs in the Basket Amount (or such other fee as the Sponsor and Administrative Trustee may establish from time to time and notify to all Authorized Participants in accordance with their respective Authorized Participant Agreements) for the Delivery of Shares pursuant to Section 2.6 and the Surrender of Baskets pursuant to Section 2.8 or 6.2(b).

(b) The Administrative Trustee is entitled to receive from the Sponsor fees for its services and reimbursement for its out-of-pocket expenses in accordance with written agreements between the Sponsor and the Administrative Trustee.

(c) The Administrative Trustee is entitled to charge the Trust for all expenses and disbursements incurred by it under Section 5.16(a) or that are of the type described in Section 4.7(a)(2) or (3) (including the fees and disbursements of its legal counsel), except that the Administrative Trustee is not entitled to charge the Trust for (i) expenses and disbursements incurred by it prior to the commencement of trading of Shares on the Exchange and (ii) fees of agents for performing services the Administrative Trustee is required to perform under this Agreement.

Section 5.13 Retention of Trust Documents. The Administrative Trustee is authorized to destroy those documents, records, bills and other data compiled during the term of this Agreement at the times permitted by the laws or regulations governing the Administrative Trustee, unless the Sponsor reasonably requests the Administrative Trustee in writing to retain those items for a longer period.

Section 5.14 Federal Securities and Commodities Law Filings. (a) The Sponsor has prepared and filed a registration statement with the SEC and shall (i) take such action as is necessary to qualify the Shares for offering and sale under the federal securities laws of the United States, including the preparation and filing of amendments and supplements to such

registration statement, (ii) promptly notify the Administrative Trustee of any amendment or supplement to the registration statement or prospectus, of any order preventing or suspending the use of any prospectus, of any request to amend or supplement the registration statement or prospectus or if any event or circumstance occurs that is known to the Sponsor as a result of which the registration statement or prospectus, as then amended or supplemented, would include an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, (iii) provide the Administrative Trustee with copies, including copies in electronic form, of the prospectus, as amended and supplemented, in such quantities as the Administrative Trustee may from time to time reasonably request and (iv) prepare, file and distribute, if applicable, any periodic reports or updates that may be required under the Exchange Act, the United States Commodity Exchange Act, as amended, or the rules and regulations thereunder. The Administrative Trustee shall furnish to the Sponsor any information from the records of the Trust that the Sponsor reasonably requests in writing as needed to prepare any filing or submission that the Sponsor or the Trust is required to make under the federal securities or commodities laws of the United States.

(b) The Sponsor shall have all necessary and exclusive power and authority to (i) adopt, implement or amend, from time to time, such disclosure and financial reporting information gathering and control policies and procedures as are necessary or desirable, in the Sponsor’s reasonable judgment, to ensure compliance with applicable disclosure and financial reporting obligations under any applicable securities laws, (ii) appoint and remove the auditors of the Trust, (iii) make any determination, choice, estimate or other decision that may be necessary or desirable in connection with the preparation of the financial statements of the Trust and (iv) seek from the relevant securities or other regulatory authorities such relief, clarification or other action as the Sponsor shall deem to be necessary or desirable regarding the disclosure or financial reporting obligations of the Trust.

Section 5.15 Prospectus Delivery. The Sponsor, or the Administrative Trustee on its behalf, will comply with the requirements to provide copies of the current prospectus for the Trust to Authorized Participants as provided in the relevant Authorized Participant Agreements.

Section 5.16 Discretionary Actions by Administrative Trustee; Consultation. (a) The Administrative Trustee may, in its discretion, undertake any action that it deems to be necessary or desirable to protect the Trust or the interests of the Registered Owners. The expenses incurred by the Administrative Trustee in connection with taking any such action (including the fees and disbursements of legal counsel) shall be expenses of the Trust, and the Administrative Trustee shall be entitled to be reimbursed for those expenses by the Trust.

(b) The Administrative Trustee shall notify and consult with the Sponsor (i) prior to undertaking any action described in Section 5.16(a) or (ii) if the Administrative Trustee becomes aware of any development or event that affects the administration of the Trust but is not contemplated or provided for in this Agreement.

Section 5.17 Trustees. The number of Trustees of the Trust initially shall be two (2), and thereafter the number of Trustees shall be such number as shall be fixed from time to time by the Sponsor. The Sponsor is entitled, subject to Section 5.9, to appoint or remove without cause any Trustee at any time; provided, however, that the number of Trustees shall in no event be less than two (2); and provided, further, that, if required by the Act, there shall at all times be a Delaware Trustee.

(c) Except as otherwise required by the Act, the Administrative Trustee is authorized to execute on behalf of the Trust any documents that the Administrative Trustee has the power and authority to cause the Trust to execute pursuant to this Agreement.

Section 5.19 Delaware Trustee. (a) The Delaware Trustee shall either be (i) a natural person who is at least twenty-one (21) years of age and a resident of the State of Delaware or (ii) a legal entity that has its principal place of business in the State of Delaware, otherwise meets the requirements of applicable Delaware law and shall act through one or more persons authorized to bind such entity. If at any time the Delaware Trustee shall cease to be eligible in accordance with the provisions of this Section 5.19, it shall resign immediately in the manner and with the effect hereinafter specified in this Section 5.19. The initial Delaware Trustee shall be Wilmington Trust Company.

(b) The Delaware Trustee shall not be entitled to exercise any powers, nor shall the Delaware Trustee have any of the duties and responsibilities, of the Administrative Trustee or the Sponsor that are set forth herein. The Delaware Trustee shall be one of the Trustees of the Trust for the sole and limited purpose of fulfilling the requirements of Section 3807 of the Act and for taking such actions as are required to be taken by a Delaware trustee under the Act. The duties (including fiduciary duties), liabilities and obligations of the Delaware Trustee shall be limited to (i) accepting legal process served on the Trust in the State of Delaware and (ii) executing any certificates required to be filed with the Delaware Secretary of State that the Delaware Trustee is required to execute under Section 3811 of the Act, and there shall be no other duties (including fiduciary duties) or obligations, express or implied, at law or in equity, of the Delaware Trustee.

The Delaware Trustee may resign at any time upon the giving of at least sixty (60) days’ advance written notice to the Administrative Trustee; provided, that such resignation shall not become effective unless and until a successor Delaware Trustee shall have been appointed by the Sponsor in accordance with

Section 5.19. If the Sponsor does not act within such sixty (60) day period, the Delaware Trustee may apply to the Court of Chancery of the State of Delaware for the appointment of a successor Delaware Trustee.

(d) Upon the resignation or removal of the Delaware Trustee, the Sponsor shall appoint a successor Delaware Trustee by delivering a written instrument to the outgoing Delaware Trustee. Any successor Delaware Trustee must satisfy the requirements of Section 3807 of the Act. Any resignation or removal of the Delaware Trustee and appointment of a successor Delaware Trustee shall not become effective until a written acceptance of appointment is delivered by the successor Delaware Trustee to the outgoing Delaware Trustee and the Sponsor and any fees and expenses due to the outgoing Delaware Trustee are paid. Following compliance with the preceding sentence, the successor Delaware Trustee (i) shall file an amendment to the Certificate of Trust reflecting the change of Delaware Trustee and (ii) shall become fully vested with all of the rights, powers, duties and obligations of the outgoing Delaware Trustee under this Agreement, with like effect as if originally named as Delaware Trustee, and the outgoing Delaware Trustee shall be discharged of its duties and obligations under this Agreement.

(e) The Sponsor shall indemnify the Delaware Trustee, its directors, employees, delegates and agents (the “Delaware Trustee Indemnified Persons”) against, and hold each of them harmless from, any Indemnified Amounts that are incurred by any of them and that arise out of or are related to (i) any offer or sale by the Trust of Baskets under this Agreement, (ii) acts performed or omitted pursuant to the provisions of this Agreement, as the same may be amended, modified or supplemented from time to time, (A) by a Delaware Trustee Indemnified Person or (B) by the Sponsor or the Administrative Trustee or (iii) any filings with or submissions to the SEC in connection with or with respect to the Shares (which, by way of illustration and not by way of limitation, include any registration statement and any amendments or supplements thereto filed with the SEC or any periodic reports or updates that may be filed under the Exchange Act or any failure to make any filings with or submissions to the SEC that are required to be made in connection with or with respect to the Shares), except that the Sponsor shall not have any obligations under this Section 5.19(e) to pay any Indemnified Amounts incurred as a result of and attributable to (x) the gross negligence or bad faith of, or material breach of the terms of this Agreement by, the Delaware Trustee or (y) information furnished in writing by the Delaware Trustee to the Sponsor expressly for use in the registration statement, or any amendment thereto, filed with the SEC relating to the Shares that is not materially altered by the Sponsor. Any such indemnity shall be subject to the provisions of Section 5.11(e).

Section 5.20 Compensation and Expenses of the Delaware Trustee. The Delaware Trustee shall be entitled to receive from the Sponsor reasonable compensation for its services hereunder as set forth in a separate fee agreement and shall be entitled to be reimbursed by the Sponsor for reasonable out-of-pocket expenses incurred by it in the performance of its duties hereunder, including the reasonable compensation, out-of-pocket expenses and disbursements of counsel and such other agents as the Delaware Trustee may employ in connection with the exercise and performance of its rights and duties hereunder.

ARTICLE VI

AMENDMENT AND TERMINATION

Section 6.1 Amendment. (a) The Administrative Trustee and the Sponsor may amend any provisions of this Agreement without the consent of any Registered Owner or Beneficial Owner. Any amendment that imposes or increases any fees or charges (other than taxes and other governmental charges) or prejudices a substantial existing right of the Registered Owners will not become effective until thirty (30) days after notice of such amendment is given by the Administrative Trustee to the Registered Owners. Every Registered Owner and Beneficial Owner, at the time any such amendment becomes effective, shall be deemed, by continuing to hold any Shares or an interest therein, to consent and agree to such amendment and to be bound by this Agreement as amended thereby. In no event shall any amendment impair the right of a Registered Owner to Surrender Baskets and receive therefor the amount of Trust Property represented thereby, except in order to comply with mandatory provisions of applicable law. Notwithstanding any other provision of this Agreement, no amendment to this Agreement may be made if, as a result of such amendment, it would cause the Trust to be taxable as an association taxable as a corporation for United States federal income tax purposes or would cause the Trust or Shares to be treated other than as described in Section 4.11(a) of this Agreement.

(b) No amendment shall be made to this Agreement without the consent of the Delaware Trustee if such amendment adversely affects any of its rights, duties or liabilities.

Section 6.2 Termination. (a) The term for which the Trust will exist commenced on the date of the filing of the Certificate of Trust and shall continue until terminated pursuant to the provisions hereof. The Administrative Trustee shall set a date on which the Trust shall dissolve and mail notice of that dissolution to the Registered Owners at least thirty (30) days prior to the date set for dissolution if any of the following occurs:

(i) the Administrative Trustee is notified that the Shares are delisted from the Exchange and are not approved for listing on another national securities exchange within five (5) Business Days of their delisting;

(ii) Registered Owners of at least 75% of the outstanding Shares notify the Administrative Trustee that they elect to dissolve the Trust;

(iii) sixty (60) days have elapsed since the Administrative Trustee notified the Sponsor of the Administrative Trustee’s election to resign, and a successor Administrative Trustee has not been appointed and accepted its appointment as provided in Section 5.9;

(iv) the SEC (or its staff) or a court of competent jurisdiction determines that the Trust is an investment company under the Investment Company Act of 1940, as amended, and the Administrative Trustee has actual knowledge of that determination;

(v) the Manager determines to liquidate the Investing Pool in accordance with the terms of the Investing Pool Agreement, which provides that the Manager may liquidate the Investing Pool at any time the Manager determines that liquidating the Investment Pool is advisable;

(vi) the Trust and/or the Investing Pool is treated as an association taxable as a corporation for United States federal income tax purposes or the Trust or the Shares are treated other than as described in Section 4.11(a) of this Agreement, and the Administrative Trustee receives notice from the Sponsor that the Sponsor has determined that termination of the Trust is advisable; or

(vii) DTC is unable or unwilling to continue to perform its functions, and a comparable replacement is unavailable.

(b) On and after the dissolution of the Trust, the Administrative Trustee shall, in accordance with Section 3808(e) of the Act, wind up the business and affairs of the Trust. Subject to the payment or the reasonable provision of such payment by the Administrative Trustee of the claims and obligations of the Trust as required by Section 3808(e) of the Act, the Registered Owners will, upon (i) Surrender of their Shares, (ii) payment of the fee of the Administrative Trustee for the Surrender of Shares provided in Section 5.12(a) and (iii) payment of any applicable taxes or other governmental charges, be entitled to Delivery, to him or upon his order, of the amount of Trust Property represented by those Shares. The Administrative Trustee shall not accept any Delivery of Basket Amounts after the date of dissolution. If any Shares remain outstanding after the date of dissolution of the Trust, the Administrative Trustee thereafter shall discontinue the registration of transfers of Shares, shall not make any distributions to Registered Owners and shall not give any further notices, except that the Administrative Trustee shall continue to collect distributions pertaining to Trust Property and hold the same uninvested and without liability for interest, pay pursuant to Section 3808(e) of the Act the Trust’s expenses and sell Trust Property as necessary to meet those expenses and shall continue to deliver Trust Property, together with any distributions received with respect thereto and the net proceeds of the sale of any other property, in exchange for Shares Surrendered to the Administrative Trustee (after deducting or upon payment of, in each case, the fee of the Administrative Trustee set forth in Section 5.12(a) for the Surrender of Shares, any expenses for the account of the Registered Owner of such Shares in accordance with the terms and conditions of this Agreement and any applicable taxes or other governmental charges). At any time after the expiration of ninety (90) days following the date of dissolution of the Trust, the Administrative Trustee may sell the Trust Property then held under this Agreement and may thereafter, after complying with Section 3808(e) of the Act, hold uninvested the net proceeds of any such sale, together with any other cash then held by it under this Agreement, unsegregated and without liability for interest, for the pro rata benefit of the Registered Owners of the Shares that have not theretofore been Surrendered, such Registered Owners thereupon becoming general creditors of the Administrative Trustee with respect to such net proceeds. After making such sale or the completion of the wind up of the business and affairs of the Trust have otherwise occurred, the Trust and this Agreement shall terminate and the Administrative Trustee shall execute and cause a certificate of cancellation of the Certificate of Trust to be filed in accordance with the Act and notify the Delaware Trustee of such filing. After making such filing, the Administrative Trustee shall be discharged from all obligations under this Agreement, except to

account for such net proceeds and other cash (after deducting, in each case, any fees, expenses, taxes or other governmental charges payable by the Trust, the fee of the Administrative Trustee for the Surrender of Shares and any expenses for the account of the Registered Owner of such Shares in accordance with the terms and conditions of this Agreement and any applicable taxes or other governmental charges).

(c) Upon the termination of this Agreement, the Sponsor shall be discharged from all obligations under this Agreement, except that its obligations to the Administrative Trustee under Sections 5.11 and 5.12 shall survive termination of this Agreement.
