The trust governed by this Agreement shall be known as "iShares® Commodity Optimized Trust." The Trustee and the Delaware Trustee filed or caused to be filed the initial Certificate of Trust with the Delaware Secretary of State on December 7, 2011 and a restated Certificate of Trust with the Delaware Secretary of State on July 1, 2014 (and are hereby authorized and directed to file any amendment thereto or restatement thereof as may be necessary or appropriate from time to time).

(b) Consistent with the investment objective set forth in Section 2.1(c), the Trust shall have full power and authority (i) to engage in such business or activities as set forth in, or contemplated by, this Agreement, the Authorized Participant Agreements and any other agreements or instruments to which, in compliance with the provisions of this Agreement, it shall become a party to or by which it may be bound, (ii) to engage in activities incidental and necessary to carry out the duties and responsibilities as set forth in, or contemplated by, this Agreement, such Authorized Participant Agreements and such other agreements or instruments and (iii) subject to the following sentence, to engage in any other lawful business, purpose or activity for which statutory trusts may be formed under the Act. Other than the Shares, the Trust shall not issue or sell any beneficial interests or other obligations or otherwise incur, assume or guarantee any indebtedness for money borrowed.

(c) The Trust's investment objective shall be to seek investment results that correspond generally, but are not necessarily identical, to the performance of the Bloomberg Roll Select Commodity Index Total Return, before the payment of expenses and liabilities of the Trust.

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 Trustee may cause legal title to the Trust Property or any portion thereof to be held by or in the name of the 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) Each Certificate 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 Trustee and, if a Registrar (other than the Trustee) for the Shares shall have been appointed, countersigned by the manual signature of a duly authorized officer of the Registrar. A Certificate bearing the manual or facsimile signature of a duly authorized signatory of the Trustee and the manual signature of a duly authorized officer of the Registrar, if applicable, who was, at the time such Certificate was executed, a proper signatory of the Trustee or the Registrar, if applicable, shall bind the Trustee, notwithstanding that such signatory has ceased to hold such office prior to the delivery of such Certificate.

(b) A Certificate 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 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 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 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 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 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 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 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 Issuance and Redemption of Shares; General. Subject to the terms of this Agreement, the Trustee shall have the power and authority, and is hereby authorized, 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.

(e) All Index Futures and Collateral Assets Delivered to the Trust as part of a Purchase Order and any other Trust Property shall be owned by the Trust and held for the Trust by the Trustee at such place and in such manner as the Trustee shall determine.

Section 2.6 Delivery of Shares. Upon receipt by the Trustee of any Delivery of the Basket Amount 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 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 reimbursement to the Trust of any extraordinary costs or expenses incurred in connection with the execution of trades related to such Purchase Order, and the payment to the Trustee of the fees and expenses of the Trust and the Trustee relating to such Purchase Order 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 Index Futures and Collateral Assets and the issuance and Delivery of the Baskets.

Thereupon, the 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 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.

Section 2.10 Lost Certificates, Etc. The 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 Trustee (i) a request for such execution and delivery before the 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 Trustee.

The 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.

ARTICLE IV

ADMINISTRATION OF THE TRUST

Section 4.1 Valuation of Trust Property.

(a) The Sponsor is hereby granted the exclusive authority to determine the Net Asset Value of the Trust and the Net Asset Value per Share, which authority it may, and hereby does, delegate to the Trustee to be exercised as set forth below, until such time as the Sponsor revokes such delegation in its sole discretion. On each Business Day on which the Exchange is open for regular trading, the Trustee shall determine the Net Asset Value of the Trust and the Net Asset Value per Share as of 4:00 p.m. (New York City time). The Trust Administrator, on behalf of the Trustee, shall value each item of Trust Property and shall communicate such valuation in a report delivered to the Trustee on each such Business Day for use by the Trustee in the determination of the Net Asset Value of the Trust, unless the Trustee determines, in consultation with the Sponsor, that such method of valuation is not appropriate as a basis for valuation of the Trust Property, in which case the Trustee will, as provided in Section 4.1(c) below, determine an alternative basis for valuation of the Trust Property. Neither the Trustee nor the Sponsor shall be liable to any Person for the determination that the most recently communicated net asset value of the Trust Property is not appropriate 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 Trustee of the Trust Administrator's report referred to above, the Trustee shall subtract all fees (other than fees computed by reference to the value of the Trust or its assets), accrued expenses and other liabilities of the Trust from the total value of the Trust Property as of the time of calculation. The resulting figure is the "Adjusted Net Asset Value" of the Trust. All fees computed by reference to the value of the Trust or its assets shall be calculated on the Adjusted Net Asset Value. The Trustee shall subtract from the Adjusted Net Asset Value all accrued fees so calculated. The resulting figure is the "Net Asset Value of the Trust." The 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 Business Day following the Order Date of such Purchase Order. Shares deliverable under a Redemption Order shall be considered to no longer be outstanding for purposes of the calculations required by this Section 4.1(b) on and after the Business Day following the Order Date of such Redemption Order.

(c) The Trustee, in consultation with the Sponsor, may (and under extraordinary circumstances as identified by the Sponsor, shall) value any asset of the Trust pursuant to such other principles as the Trustee deems fair and equitable so long as such principles are consistent with industry standards. For purposes of the foregoing, "extraordinary circumstances" shall include, but not be limited to, periods during which a valuation price for a forward contract or a settlement price of a futures contract is not available due to force majeure-type events such as systems failure, natural or man-made disaster, act of God, armed conflict, act of terrorism, riot or labor disruption or any similar intervening circumstance or due to a trading or other restriction imposed by a relevant Futures Exchange.

Section 4.2 Responsibility of the Trustee for Determinations. The determinations made by the Trustee under this Agreement shall be made in good faith upon the basis of, and the Trustee shall not be liable for any errors contained in, information reasonably available to it. Neither the Sponsor nor the Trustee shall be under liability to the Depositors, the Registered Owners, the Beneficial Owners or each other for errors in judgment; provided, however, that this provision shall not protect the 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. The Sponsor shall have the exclusive authority to cause the Trust to distribute any Trust Property to the Registered Owners in accordance with this Agreement, which authority it may, and hereby does, delegate to the Trustee, until such time as the Sponsor revokes such delegation in its sole discretion. Whenever the Trustee distributes any cash, the 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 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 Trustee distributes any non-cash proceeds (including claims and other intangibles) in respect of Trust Property other than property subject to distribution in accordance with the creation and redemption procedures set forth herein, as supplemented by the Authorized Participant Agreements, the Trustee shall cause such non-cash proceeds 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 Trustee, in any manner that the Trustee may deem to be lawful, equitable and feasible for accomplishing such distribution; provided, however, that if in the opinion of the Trustee such distribution cannot be made proportionately among the Registered Owners entitled thereto, or if for any other reason (including any requirement that the 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 Trustee deems such distribution not to be lawful and feasible, the 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 Trustee, including the public or private sale of the non-cash proceeds thus received, or any part thereof, and the net proceeds of any such sale shall be distributed by the Trustee to the Registered Owners entitled thereto as in the case of a distribution received in cash.

Section 4.5 Fixing of Record Date. Whenever any distribution will be made, or whenever the 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 Trustee shall find it necessary or convenient in respect of any matter, the 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 4.6 Payment of Expenses; Sales of Trust Property.

(a) The following charges may be accrued and shall be paid by the Trust:

(i) any expenses of the Trust not assumed by the Sponsor pursuant to Section 5.7(f), including any applicable brokerage commissions and any applicable transaction fees;

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

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

(iv) any indemnification of a Sponsor Indemnified Party as provided in Section 5.11(d) or any indemnification of any Advisor Indemnified Party as defined in and pursuant to the Advisory Agreement; and

(v) the fee payable to the Sponsor pursuant to Section 5.13.

(b) The 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 Trustee nor the Sponsor shall have any liability for loss or depreciation resulting from sales of Trust Property so made. The 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 4.6 or as contemplated in Section 4.8.

(c) Except as provided in this Agreement, the Trust shall have no obligation to make any distribution to any Registered Owners or Beneficial Owners. If, at any time and from time to time, the Sponsor determines that the amount of cash included in the Trust Property exceeds the reasonably anticipated expenses of the Trust, the Sponsor may, in its sole discretion, direct the Trustee to distribute the excess cash to the Registered Owners under Section 4.3.

Section 4.7 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 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 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 Trustee may distribute the annual report by any means acceptable to such Registered Owners.

(b) The 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 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 4.8 Further Provisions for Sales of Trust Property. In addition to selling Trust Property in accordance with Section 4.6, the Trustee shall sell Trust Property whenever either or both of the following conditions exist:

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

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

The 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 4.8.

Section 4.9 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 Trust Property. 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 4.10 Tax Matters.

(a) The Trustee, at its expense, shall prepare or cause to be prepared all federal, state, and local tax returns of the Trust for each year for which such returns are required to be filed and shall file or cause such returns to be timely filed and shall timely pay (or cause to be timely paid) any tax, assessment or other governmental charge owing with respect to the Trust out of Trust Property. The 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 Trustee shall deliver or cause to be delivered to each Beneficial Owner, and the broker or nominee through which a Beneficial Owner owns its Shares, a Schedule K-1 and such other information, if any, with respect to the Trust as may be necessary for the preparation of the federal income tax or information returns of such Beneficial Owner including a statement showing each Beneficial Owner's share of income, gain, loss, expense, deductions and credits for such fiscal year for U.S. federal income tax purposes 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 Trustee shall obtain a taxpayer identification number for the Trust. The Trust hereby indemnifies, to the full extent permitted by law, the 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 4.10(a), to the extent that such action taken or omitted to be taken does not constitute fraud, negligence or misconduct. Each Beneficial Owner agrees that it shall not, except as required by applicable law, (i) treat, on its own income or information tax returns or any information returns that it provides to any Beneficial Owner, or to any broker or nominee through which the Beneficial Owner owns its Shares, any item of income, gain, loss, deduction, credit, basis or any other tax item relating to its Shares in a manner inconsistent with the treatment of such items by the Trust as reflected on the Schedule K-1 or other information statement furnished to such Beneficial Owner pursuant to this Section 4.10(a), or (ii) file any claim for a refund relating to any such item based on, or which would result in, such inconsistent treatment.

(b) The parties hereto and, by its acceptance or acquisition of a Share or a beneficial interest therein and continued ownership thereof, a Beneficial Owner and the broker or nominee through which the Beneficial Owner owns its Share (i) agree to furnish the Sponsor and the Trustee with such representations, forms, documents or information as may be necessary to enable the Trust to comply with its U.S. federal income tax reporting obligations in respect of such Share and to allow the Trust 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 required by Treasury Regulations Section 1.6031(c)-1T and any successor thereto and (ii) direct brokers and nominees to report to the Trustee the Beneficial Owner's name and address and such other information as may be reasonably requested by the Trustee for purposes of complying with the Trust's U.S. federal income tax reporting obligations or as necessary to allow the Trust to make the basis adjustments permitted by Section 754 of the Code, including information required by Treasury Regulations Section 1.6031(c)-1T and any successor thereto.

(c) Except as provided herein, the Tax Matters Partner may, in its sole discretion, cause the Trust to make, or refrain from making, any income or other tax elections that the Tax Matters Partner reasonably deems necessary or advisable, including, but not limited to, an election pursuant to Section 754 of the Code. The Tax Matters Partner intends to make the election under Section 754 of the Code. The Beneficial Owners recognize and intend that the Trust will be classified as a partnership for U.S. income tax purposes, and will not cause the Trust to make an election to be treated as an association taxable as a corporation for U.S. federal income tax purposes pursuant to Treasury Regulations Section 301.7701-3, or any successor provision, or a similar election under any analogous provision for purposes of state or local law. To the extent necessary, the Trust or the Beneficial Owners (as appropriate) will make any election necessary to obtain treatment consistent with the foregoing.

(d) If the Trust makes an election pursuant to Section 754 of the Code, the Beneficial Owners agree that the basis of Shares and property of the Trust shall be determined taking into account the provisions of Sections 734(b) and 743(b) of the Code, and except as required by applicable law the Beneficial Owners shall report the basis of their Shares or any property of the Trust distributed to the Beneficial Owners or their agents in a redemption as equal to the basis reported by the Trust or its agents to such Beneficial Owners. The Beneficial Owners acknowledge that, to the extent any Beneficial Owner is subject to the xxxx-to-market rules of Section 475 of the Code, the basis of Shares and of any property of the Trust, including property distributed to a Beneficial Owner in a redemption, shall be determined, including for purposes of Sections 734(b) and 743(b) of the Code, by treating such xxxx-to-market as having no effect on such basis.

(e) Each Beneficial Owner acknowledges that the Trust may report gain or loss and other tax items, including the allocation of basis and adjustments to basis, in reliance upon the assumption that any redemption of a Beneficial Owner's Share is a distribution other than in liquidation of the Beneficial Owner's Share (a "partial redemption"), unless it notifies the Trust or its agent prior to such distribution that such distribution is in liquidation of the Beneficial Owner's Share (a "complete redemption"). The Beneficial Owner agrees to notify the Trust or its agent within 5 Business Days of any distribution of (i) any gain or loss arising from a redemption of a Share by the Beneficial Owner or its agent in exchange for such property, and (ii) any difference between the tax basis of such property on the books of the Trust immediately prior to the redemption, as such amount is reported to the Beneficial Owner or its agent, and the basis of the distributed property to the Beneficial Owner or its agent (such gain or loss or basis difference, "Section 734(b) items") in a manner sufficient for the Trust to adjust the basis of undistributed property held by the Trust under Section 734(b) of the Code if the Trust makes an election pursuant to Section 754 of the Code. Each Beneficial Owner agrees to determine its basis for tax purposes in any property it or its agent receives from the Trust in consideration for a redemption of Shares by reference to the tax basis of such property on the books of the Trust immediately prior to the redemption, as such amount is reported to the Beneficial Owner or its agent by the Trust, subject to adjustment as required under Section 732 or other applicable law.

(f) The Trust shall comply with all applicable withholding and backup withholding tax requirements. The Trust shall request, and each Beneficial Owner shall provide to the Trust, and direct any broker or nominee through which the Beneficial Owner owns its Shares to provide to the Trust, such forms or other documentation as are necessary to establish an exemption from or reduction in 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 Trust 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 Trustee reasonably believes that the Trust 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 Trust 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 property otherwise distributable to such Beneficial Owner. If an amount required to be withheld is 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.

(g) 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 4.10(f) of this Agreement or (ii) enable the Trust to comply with its U.S. federal income tax reporting obligations, or to allow the Trust to make the basis adjustments under Section 754 of the Code with respect to such Share, pursuant to Section 4.10(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 4.10(b), 4.10(f) and 4.10(g).

(h) The Sponsor, or such other person that is designated by the Sponsor, shall act as the Tax Matters Partner and exercise any authority permitted the Tax Matters Partner under the Code and Treasury Regulations, and take whatever steps the Sponsor, or such other person as is designated by the Sponsor to act as the Tax Matters Partner, in its reasonable discretion, deems necessary or desirable to perfect such designation, including (i) filing any forms and documents with the Internal Revenue Service, (ii) retaining ownership of Shares for as long as it acts as the Tax Matters Partner as may be required under the Code and Treasury Regulations, and (iii) taking such other action as may from time to time be required under the Code or Treasury Regulations.

Section 5.4 Prevention or Delay in Performance by the Sponsor or the Trustee. Neither the Sponsor nor the 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 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 Trustee does not do that thing or does that thing at a later time than would otherwise be required.

The parties hereto shall not have any implied duties (including fiduciary duties) or liabilities otherwise existing at law or in equity with respect to the Trust or any other Person. To the extent that, at law or in equity, the Trustee or the Sponsor has duties (including fiduciary duties) and liabilities relating thereto to the Trust, the Registered Owners, the Beneficial Owners, the Authorized Participants, the Depositors or any other Person, the Trustee and the Sponsor acting under this Agreement shall not be liable to the Trust, the Registered Owners, the Beneficial Owners, the Authorized Participants, the Depositors or any other Person for its good faith reliance on the provisions of this Agreement subject to the standard of care in Section 5.5.

For the avoidance of doubt, no Person other than the parties hereto shall have any duties or obligations hereunder to the Trust, any Registered Owner, any Beneficial Owner, the Authorized Participants or the Depositors.

(b) Unless otherwise expressly provided herein:

(i) whenever a conflict of interest exists or arises between the 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 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 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 Trustee or the Sponsor, the resolution, action or terms so made, taken or provided by the 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 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 Trustee or the Sponsor is permitted or required to make a decision:

(i) in its "discretion" or under a grant of similar authority, the Trustee or the Sponsor shall be entitled to consider such interests and factors as it desires, including its own interests, and, to the fullest extent permitted by applicable law, shall have no duty or obligation to give any consideration to any interest of or factors affecting the Trust, any Registered Owner, any Beneficial Owner, any Authorized Participant, any Depositor or any other Person; or

If the 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 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 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 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.

The Trustee may terminate any such delegee at any time and is not required to appoint a replacement therefor.

Section 5.9 Resignation or Removal of the Trustee; Appointment of Successor Trustee.

(a) The Trustee may at any time resign as 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 Trustee and its acceptance of such appointment as hereinafter provided.

(b) The Sponsor may remove the Trustee in its discretion by written notice delivered to the Trustee in the manner provided in Section 7.4 at any time after the first anniversary of the date hereof.

Section 5.10 Custodians. The 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 Trustee is further authorized to appoint any successor or replacement Custodian or terminate any previously appointed Custodian, in accordance with the terms of the applicable custodial or other agreements entered into by the Trust with such Custodian or Custodians.

Section 5.11 Indemnification.

(a) The Sponsor shall indemnify the Trustee, its directors, employees, delegees and agents (the "Trustee Indemnified Persons") against, and hold each of them harmless from, any loss, liability, claim, cost, expense or judgment of any kind whatsoever (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 a 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 Trustee, (y) information furnished in writing by the 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 Trustee shall indemnify the Sponsor, its directors, employees, delegees and agents against, and hold each of them harmless from, any Indemnified Amounts (i) caused by the negligence or bad faith of the Trustee or (ii) arising out of any information furnished in writing to the Sponsor by the 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 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 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 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 and agents (each, a "Sponsor Indemnified Party") shall be indemnified from the Trust and held harmless against any Indemnified Amounts 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 or willful misconduct 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.

The 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 or the laws of any other jurisdiction.

(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; provided, however, that to the extent applicable laws, regulations or the listing rules of the Exchange contemplate that one or more of the powers vested in the Sponsor hereby be exercised by an audit committee, then the audit committee of the Sponsor's board of directors shall have exclusive power and authority to exercise such powers.

ARTICLE VI

AMENDMENT AND TERMINATION

Section 6.1 Amendment.

(a) The Sponsor and the Trustee may amend any provision 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 the Sponsor's Fee, to the extent it does not exceed 0.75% of the Adjusted Net Asset Value, and 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 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, without the consent of Registered Owners representing a majority of the outstanding Shares, no amendment to this Agreement may be made if, as a result of such amendment, it would cause the Trust to be treated as an association taxable as a corporation for United States federal income tax purposes.

(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 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:

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

(iii) sixty (60) days have elapsed since the Trustee notified the Sponsor of the Trustee's election to resign, and a successor 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 Trustee has actual knowledge of that determination;

(v) the Sponsor notifies the Trustee in writing that it has determined, in its sole discretion, that the dissolution of the Trust is advisable;

(vi) the Trust is treated as an association taxable as a corporation for United States federal income tax purposes and the 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 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 Trustee of the claims and obligations of the Trust as required by Section 3808(e) of the Act, the Registered Owners will be entitled to delivery to them of the amount of Trust Property represented by their Shares as hereinafter provided. The Trustee shall not accept any Purchase Order or Redemption Order after the date of dissolution. If any Shares remain outstanding after the date of dissolution of the Trust, the Trustee thereafter shall (i) discontinue the registration of transfers of Shares; (ii) continue to collect distributions pertaining to Trust Property and hold the proceeds thereof uninvested, without liability for interest; and (iii) pay pursuant to Section 3808(e) of the Act the Trust's expenses, and may sell Trust Property as necessary to meet those expenses. After the dissolution of the Trust, the Trustee shall sell or otherwise liquidate the Trust Property then held under this Trust Agreement and, after complying with Section 3808(e) of the Act and deducting any fees, expenses, taxes or other governmental charges payable by the Trust and any expenses for the account of the Registered Owner of such Shares in accordance with the terms and conditions of this Trust Agreement and any applicable taxes or other governmental charges, promptly distribute the net proceeds from such sale to the Registered Owners. After making such distribution, the Trust and this Trust Agreement shall terminate and the Trustee and the Delaware Trustee shall execute and cause a certificate of cancellation of the Certificate of Trust to be filed in accordance with the Act. After making such filing, the Trustee and the Delaware Trustee shall be discharged from all obligations under this Trust Agreement.

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

ANNEX I

CAPITAL ACCOUNTS, DISTRIBUTIONS AND ALLOCATIONS

Section 1 Capital Accounts.

(a) The Trust shall establish and maintain a separate account (the "Capital Account") for each Beneficial Owner's Shares in accordance with the following provisions (references to Sections in this Annex I will be to Sections in this Annex I unless otherwise stated and references to Sections of the Agreement will be indicated as such):

(i) Initial Contribution. A Beneficial Owner's "Initial Contribution" will be equal to the amount of cash and the value (as determined under Section 7 of this Annex I) of any Index Futures or Short-Term Securities contributed to the Trust by the Beneficial Owner or its agent on the first issuance of Shares to the Beneficial Owner or its agent as described in Article II.

(ii) Initial Capital Account. The initial balance of the Capital Account of each Beneficial Owner shall be such Beneficial Owner's Initial Contribution.

(iii) Adjustments to Capital Accounts.

(A) Each Beneficial Owner's Capital Account shall be increased by the amount of additional cash and the value (as determined under Section 7 of this Annex I) of any Index Futures or Short-Term Securities contributed to the Trust by such Beneficial Owner or its agent, and by any income or gain (including income and gain exempt from tax) computed in accordance with Section 1(b) and allocated to such Beneficial Owner pursuant to Section 2.

(B) Each Beneficial Owner's Capital Account shall be decreased by the amount of cash and the value (as determined under Section 7 of this Annex I) of any Index Futures or Short-Term Securities distributed to such Beneficial Owner or its agent pursuant to any provision of this Agreement, and by any expenses, deductions or losses computed in accordance with Section 1(b) and allocated to such Beneficial Owner pursuant to Section 2.

(iv) Contributions; Distributions; Redemptions.

(A) Each Beneficial Owner agrees that it (or its agent) will contribute property to the Trust only if such property has, to the best of that Beneficial Owner's knowledge after reasonable inquiry, a basis for tax purposes equal to the fair market value of such property, and acknowledges that the Trust will rely upon such fair market value basis for purposes of determining and allocating items of income, gain, loss, deduction, basis and other tax items. For this purpose, Section 7 shall apply to determine fair market value.

I-1

(B) In determining which Index Futures and Short-Term Securities, if any, are to be distributed to a Beneficial Owner or its agent or sold or closed out in connection with a redemption pursuant to the provisions of this Agreement, the Trustee shall adopt a standard procedure for selecting such Index Futures or Short-Term Securities that is applied consistently to all redemptions. Unless the Trustee determines that another lot selection method more accurately allocates taxable gain and loss to Beneficial Owners in a manner that corresponds to their economic gain and loss, the procedure shall be "first in, first out."

(b) For purposes of computing the amount of any item of income, gain, deduction, expense or loss to be reflected in a Beneficial Owner's Capital Account, the determination, recognition and classification of any such item shall be the same as its determination, recognition and classification for U.S. federal income tax purposes; provided that:

(i) Items described in Section 705(a)(2)(B) of the Code shall be treated as items of deduction. All fees and other expenses incurred by the Trust to promote the sale of (or to sell) a Share that can neither be deducted nor amortized under Section 709 of the Code shall, for purposes of Capital Account maintenance, be treated as an item described in Section 705(a)(2)(B) of the Code.

(ii) Except as otherwise provided in Treasury Regulations Section 1.704-1(b)(2)(iv)(m), the computation of all items of income, gain, loss and deduction shall be made without regard to any election under Section 754 of the Code.

(iii) In computing income, gain, deduction, expense or loss for Capital Account purposes, the amount of such item shall be determined taking into account the book value of the Trust's property, as adjusted pursuant to Section 1(d).

(c) In the event any Beneficial Owner's Shares are transferred in accordance with the terms of this Agreement, the transferee shall succeed to the Capital Account of such Beneficial Owner to the extent such Capital Account relates to the transferred Shares.

(d) Consistent with the provisions of Treasury Regulations Section 1.704-1(b)(2)(iv)(f), upon an issuance or redemption of Shares, in connection with the dissolution, liquidation or termination of the Trust, or otherwise as appropriate pursuant to generally accepted industry accounting practices, the Capital Accounts of all Beneficial Owners may, immediately prior to such issuance, redemption, dissolution, liquidation, termination, or otherwise, be adjusted (consistent with the provisions hereof) upwards or downwards to reflect any Unrealized Gain or Unrealized Loss attributable to Trust property, as if such Unrealized Gain or Unrealized Loss had been recognized upon an actual sale of such property, immediately prior to such issuance, redemption, dissolution, liquidation, termination, or otherwise, and had been allocated to the Beneficial Owners at such time pursuant to Section 2. Pursuant to Treasury Regulations Section 1.704-1(b)(2)(iv)(g), appropriate adjustments shall be made to the book value of Trust property with Unrealized Gain or Unrealized Loss. Proper adjustment shall be made to the amount of any Capital Account adjustment under this Section 1(d) to take into account any prior Capital Account adjustment under this Section 1.

I-2

Section 2 Allocations for Capital Account Purposes.

(a) For purposes of maintaining Capital Accounts and in determining the rights of the Beneficial Owners among themselves, except as otherwise provided in this Section 2, each item of income, gain, loss, expense and deduction (computed in accordance with Section 1(b)) shall be allocated to the Beneficial Owners in accordance with their respective Percentage Interests.

(b) Pursuant to Treasury Regulations Section 1.704-1(b)(2)(iv)(g), items of depreciation, depletion, amortization and gain or loss attributable to Adjusted Property that has a Book-Tax Disparity shall be allocated among the Beneficial Owners in accordance with Treasury Regulations Section 1.704-1(b)(2)(iv)(g)(3).

(c) If any Beneficial Owner unexpectedly receives any adjustments, allocations or distributions described in Treasury Regulations Section 1.704-1(b)(2)(ii)(d)(4), 1.704-1(b)(2)(ii)(d)(5) or 1.704-1(b)(2)(ii)(d)(6), then items of Trust income and gain (consisting of a pro rata portion of each item of Trust income, including gross income, and gain for such year) shall be specially allocated to such Beneficial Owner in an amount and manner sufficient to eliminate a deficit balance in its Capital Account (after decreasing such Beneficial Owner's Capital Account balance by the items described in Treasury Regulations Section 1.704-1(b)(2)(ii)(d)(4), 1.704-1(b)(2)(ii)(d)(5) and 1.704-1(b)(2)(ii)(d)(6)) created by such adjustments, allocations or distributions as quickly as possible. This Section 2(c) is intended to constitute a "qualified income offset" within the meaning of Treasury Regulations Section 1.704-1(b)(2)(ii)(d).

Section 3 Allocations for Tax Purposes.

(a) For U.S. federal income tax purposes, except as otherwise provided in this Section 3, each item of income, gain, loss, deduction and credit of the Trust shall be allocated among the Beneficial Owners in accordance with their respective Percentage Interests.

(b) In an attempt to eliminate Book-Tax Disparities, items of income, gain, loss, or deduction shall be allocated for U.S. federal income tax purposes among the Beneficial Owners under the remedial allocation method of Treasury Regulations Section 1.704-3(d).

(d) The provisions of this Annex I and the other provisions of this Agreement relating to the maintenance of Capital Accounts are intended to comply with Treasury Regulations Section 1.704-1(b) and shall be interpreted and applied in a manner consistent with such Regulations. The Trustee shall be authorized to make appropriate amendments to the allocations of items pursuant to this Section 3 if necessary in order to comply with Section 704 of the Code or applicable Treasury Regulations promulgated thereunder.

Section 4 Tax Conventions.

(a) For purposes of Sections 1, 2 and 3, the Trustee shall cause the Trust to adopt such conventions as may be necessary or appropriate in the Trustee's reasonable discretion in order to comply with applicable law, including Section 706 of the Code and the Treasury Regulations or rulings promulgated thereunder, or to allocate items of the Trust's income, gain, loss, expenses, deductions and credits in a manner that reflects Beneficial Owner's Shares. The Trustee may revise, alter or otherwise modify such conventions in accordance with the standard established in the prior sentence.

I-3

(b) Unless the Trustee determines that another convention is necessary or appropriate in the Trustee's reasonable discretion in order to comply with applicable law, or to allocate items of the Trust's income, gain, loss, expenses, deductions and credits in a manner that more accurately reflects Trustee's Shares, the Trust shall use the monthly convention described in this Section 4(b).

(i) All issuances, redemptions and transfers of Shares or beneficial interests therein shall be deemed to take place at a price equal to the value of such Share or beneficial interest therein at the end of the Business Day during the month in which the issuance, redemption or transfer takes place on which the value of a Share is lowest (such price, the "single monthly price"). Accordingly, in determining Unrealized Gain or Unrealized Loss and in making the adjustments provided for by Section 1(d), the fair market value of all Trust property immediately prior to the issuance, redemption or transfer of Shares shall be deemed to be equal to the lowest value of such property (as determined under Section 7) during the month in which such Shares are issued or redeemed. In the event that the Trust makes an election under Section 754 of the Code, adjustments to be made under Sections 734(b) and 743(b) of the Code will be made using the same monthly convention, including by reference to the single monthly price.

(ii) All contributed property shall be deemed to be contributed at a price equal to the weighted average value of such property (as determined under Section 7) during the month in which such property is contributed. All purchases and sales of property, however, shall be treated as taking place at a price equal to the purchase or sales price of the property, respectively.

(iii) Each item of Trust income, gain, expense, loss, deduction and credit attributable to transferred Shares shall, for U.S. federal income tax purposes, be determined on a monthly basis and shall be allocated to the Beneficial Owners who own Shares as of the close of the last day of the month preceding the month in which the transfer occurs, provided that, for the initial period beginning on the date hereof and ending on the last day of the month following the month in which this Agreement becomes effective, such items shall be allocated to the Beneficial Owners who own the Shares as of the close of the last day of the month in which such items arose; and provided further that, unless the Trustee determines that another method is necessary or appropriate in the Trustee's reasonable discretion, gain or loss on a sale or other disposition of all or a substantial portion of the assets of the Trust (or, in the Trustee's sole discretion, other sales or dispositions of assets if appropriate to more accurately allocate such gain and loss to Beneficial Owners in a manner that corresponds to their economic gain and loss) shall be allocated to the Beneficial Owners who own Shares as of the close of the day in which such gain or loss is recognized for U.S. federal income tax purposes.

I-4

(iv) All such allocations are intended to constitute a reasonable method of allocation in accordance with Treasury Regulations Section 1.706-1(c)(2)(ii) and to take into account a Beneficial Owner or Beneficial Owner's varying Shares during the taxable year of any issuance, redemption or transfer of Shares or beneficial interests therein. Any person who is the transferee of Shares shall be deemed to consent to the methods of determination and allocation set forth in this Section 4 as a condition of receiving such Shares.

Section 5 Shares as Personal Property. Each Beneficial Owner hereby agrees that its Shares shall for all purposes be personal property. The Trust shall be the sole owner of the property and rights conveyed to it. No Beneficial Owner has any interest in specific Trust property, including property conveyed to the Trust by a Beneficial Owner.

Section 6 Interest on Capital Contributions. No Beneficial Owner shall be entitled to any interest on its capital contribution.

Section 7 Valuation.

(a) Unless otherwise provided in this Agreement, the value, on any day, of Index Futures, Short-Term Securities and any other property, other than cash, under this Agreement shall be determined as of 4:00 p.m. (New York City time) on that day, as follows:

(i) The Trustee will value Index Futures on the basis of that day's applicable settlement price for each Index Future as announced by the Futures Exchange on which such Index Future is listed. If there is no settlement price announced by the Futures Exchange for a Index Future on that day, the Trustee will use the most recently announced settlement price for such Index Future unless the Trustee determines that that price is inappropriate as a basis for the valuation of such Index Future, in which case the Trustee shall value such Index Future as described in paragraph (ii) below.

(ii) The Trustee will value all other property at (A) its current market value, if quotations for such property are readily available or (B) its fair value, as reasonably determined by the Trustee, if no quotations for such property are readily available.

(b) The Trustee may (but is not required to) employ the services of, and rely upon the reports of, a recognized pricing service (including a pricing service that is an Affiliate of the Trustee). If the Trustee determines that the procedures in this Section 7 are an inappropriate basis for the valuation of the Trust's assets, it shall determine an alternative basis to be employed. The Trustee shall not be liable to any Person for any determination as to the alternative basis for evaluation; provided that such determination is made in good faith.

Section 8 Distributions.

(a) Distributions from the Trust upon the occurrence of a redemption or upon dissolution, liquidation or termination pursuant to Section 2.8 or 6.2 of the Agreement, will be in the form of Index Futures, Short-Term Securities and/or cash as determined by such sections, as applicable; provided that, in the case of a distributions upon dissolution, liquidation or termination, amounts received by Beneficial Owners shall be in accordance with Capital Accounts as provided in Treasury Regulations Section 1.704-1(b)(2)(ii)(b).

I-5

(b) Notwithstanding any provision to the contrary contained in this Agreement, the Trust, and the Trustee on behalf of the Trust, shall not be required to make a distribution with respect to Shares if such distribution would violate the Act or any other applicable law. A determination that a distribution is not prohibited under this Section 8 or the Act shall be made by the Trustee and, to the fullest extent permitted by applicable law, may be based either on financial statements prepared on the basis of accounting practices and principles that are reasonable under the circumstances or on a fair valuation or any other method that is reasonable under the circumstances. Unless otherwise agreed to by the Beneficial Owners, a Beneficial Owner shall be entitled only to the distributions expressly provided for in this Agreement.

(c) Notwithstanding anything to the contrary contained in this Agreement, the Beneficial Owners understand and acknowledge that a Beneficial Owner (or its agent) may be compelled to accept a distribution of any asset in kind from the Trust despite the fact that the percentage of the asset distributed to such Beneficial Owner (or its agent) exceeds the percentage of that asset which is equal to the percentage in which such Beneficial Owner shares in distributions from the Trust.
