Ladies and Gentlemen:

BlackRock Asset Management International Inc., a Delaware corporation (the “Sponsor”), has sponsored the formation of an investment trust, known as “iShares^® Copper Trust” (the “Trust”), pursuant to the laws of the State of New York for which The Bank of New York Mellon acts as trustee (the “Trustee”). Upon the basis of the representations and warranties set forth in Section 1 hereof and subject to the applicable terms and conditions set forth herein, the Trust will issue and sell to you (the “Initial Purchaser”) an aggregate of [        ] units of fractional undivided beneficial interest in and ownership of the Trust (the “Shares” and, such [        ] units of Shares, the “Purchased Shares”) upon the deposit by the Initial Purchaser with Metro International Trade Services LLC, acting as custodian of the Trust (in such capacity, the “Custodian”), of an aggregate amount of [        ] tonnes of copper in physical form (corresponding to [        ] baskets as described in the Prospectus (as defined herein), the “Initial Deposit”).

1. The Sponsor, on its own behalf and in its capacity as sponsor of the Trust, represents and warrants to, and agrees with, the Initial Purchaser that:

(a) A registration statement on Form S-1 File No. 333-170131 (the “Initial Registration Statement”), and Amendments Nos. 1-[—] thereto, in respect of the Shares have been filed with the Securities and Exchange Commission (the “Commission”) in the form heretofore delivered to you; no other document with respect to the Initial Registration Statement has heretofore been filed with the Commission; Amendment No. [—] to the Initial Registration Statement, and as part thereof a final prospectus, in the form heretofore delivered to you is now proposed to be filed with the Commission; and no other amendment thereto will be filed prior to the time the Initial Registration Statement becomes effective which shall be disapproved by you promptly after written notice thereof (any preliminary prospectus included in the Initial Registration Statement or filed with the Commission pursuant to Rule 424(a) of the rules and regulations of the Commission under the Securities Act of 1933, as amended (the “Act”), is hereinafter called a “Preliminary Prospectus”; the various parts of the Initial Registration Statement, including all exhibits thereto, each as amended at the time such part of the Initial Registration Statement becomes effective, are hereinafter collectively called the “Registration Statement”; such final prospectus is hereinafter called the “Prospectus”; and any “issuer free writing prospectus” as defined in Rule 433 relating to the Shares is hereinafter called an “Issuer Free Writing Prospectus”);

(b) The Registration Statement and the Prospectus and any further amendments or supplements thereto, when they become effective or are filed with the Commission, as the case may be, will conform in all material respects to the requirements of the Act and the rules and regulations of the Commission thereunder and will not as of the applicable effective date as to the Registration Statement and any amendment thereto or as of the applicable filing date as to the Prospectus and any amendment or supplement thereto, contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading; provided, however, that this representation and warranty shall not apply to any statements or omissions made in reliance upon and in conformity with information furnished in writing to the Sponsor by the Initial Purchaser expressly for use therein;

(c) Since the respective dates as of which information is given in the Registration Statement and the Prospectus, there shall not have been any (i) material adverse change, or any development involving a prospective material adverse change affecting the Sponsor or the Trust, (ii) transaction which is material to the Trust taken as a whole, (iii) obligation, direct or contingent (including any off-balance sheet obligations), incurred by the Sponsor or the Trust, which is material to the Trust taken as a whole, (iv) change in the outstanding indebtedness of the Trust, or (v) dividend or distribution of any kind declared, paid or made on the Shares;

(g) The issue and sale of the Shares by the Trust and the compliance by the Sponsor and the Trust with all of the provisions of this Agreement and the consummation of the transactions herein contemplated will not conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument to which the Sponsor or the Trust is a party or by which the Sponsor or the Trust is bound or to which any of the property or assets of the Sponsor or the Trust is subject except where such conflict, breach or violation, as the case may be, would not have a material adverse effect on the ability of the Sponsor or the Trust to perform

- 2 -

its obligations under this Agreement, nor will such action result in any violation of the provisions of the constitutive documents of the Sponsor or the Trust, or any statute or any order, rule or regulation of any court or governmental agency or body having jurisdiction over the Sponsor or the Trust or any of their properties, except where such violation would not have a material adverse effect on the ability of the Sponsor or the Trust to perform its obligations under this Agreement; and no consent, approval, authorization, order, registration or qualification of or with any such court or governmental agency or body is required for the issue and sale of the Shares hereunder or the consummation by the Sponsor or the Trust of the transactions contemplated by this Agreement, except the registration of the Shares under the Act and such consents, approvals, authorizations, registrations or qualifications as may be required under the rules of state securities or Blue Sky laws in connection with the purchase and distribution of the Purchased Shares by the Initial Purchaser;

(j) Other than as set forth in the Prospectus, there are no legal or governmental proceedings pending to which the Sponsor or the Trust is a party or of which any property of the Sponsor or the Trust is the subject which, if determined adversely to the Sponsor or the Trust, would individually or in the aggregate have a material adverse effect on the current or future consolidated financial position, shareholders’ equity or results of operations of the Sponsor or the Trust; and, to the best of the Sponsor’s knowledge, no such proceedings are threatened or contemplated by governmental authorities or threatened by others;

(l) As of the Closing Time, (i) the audited statement of financial condition included in the Prospectus, together with the related notes and schedules, presents fairly the financial position of the Trust as of the date indicated and has been prepared in compliance with the requirements of the Act and in conformity with generally accepted accounting principles, (ii) there are no financial statements (historical or pro forma) that are required to be included in the Registration Statement and the Prospectus that are not included as required, and (iii) the Trust does not have any material liabilities or obligations, direct or contingent (including any off-balance sheet obligations), not disclosed in the Registration Statement and the Prospectus;

(p) Except as set forth in the Registration Statement and in the Prospectus, (i) no person has the right, contractual or otherwise, to cause the Trust to issue or sell to it any Shares or other equity interest of the Trust, and (ii) no person has the right to act as an underwriter or as a financial advisor to the Trust in connection with the offer and sale of the Shares, in the case of each of the foregoing clauses (i) and (ii), whether as a result of the filing or effectiveness of the Registration Statement or the sale of the Shares as contemplated thereby or otherwise; no person has the right, contractual or otherwise, to cause the Sponsor on behalf of the Trust to register under the Act any other equity interests of the Trust, or to include any such shares or interests in the Registration Statement or the offering contemplated thereby, whether as a result of the filing or effectiveness of the Registration Statement or the sale of the Shares as contemplated thereby or otherwise;

(q) To the best of the Sponsor’s knowledge, and except as set forth in the Registration Statement and the Prospectus or as otherwise disclosed by the Sponsor to the Initial Purchaser in writing, there is no pending or threatened action, suit, proceeding or claim by others that the Sponsor or the Trust infringes or otherwise violates any patent, trademark, copyright, trade secret or other proprietary rights of others, and the Sponsor and the Trust are unaware of any facts which could form a reasonable basis for any such claim; and

7. (a) The Sponsor, in its capacity as Sponsor of the Trust, represents and agrees that, without the prior consent of the Initial Purchaser, it has not made and will not make any offer relating to the Purchased Shares that would constitute a “free writing prospectus” as defined in Rule 405 under the Act; the Initial Purchaser represents and agrees that, without the prior consent of the Sponsor, it has not made and will not make any offer relating to the Purchased Shares that would constitute a free writing prospectus; any such free writing prospectus the use of which has been consented to by the Sponsor and Initial Purchaser is listed on Schedule I hereto;

contained in any Preliminary Prospectus, the Registration Statement, any Issuer Free Writing Prospectus or the Prospectus, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse the Initial Purchaser for any legal or other expenses reasonably incurred by the Initial Purchaser in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the Sponsor shall not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in any Preliminary Prospectus, the Registration Statement, any Issuer Free Writing Prospectus or the Prospectus or any such amendment or supplement in reliance upon and in conformity with written information furnished to the Sponsor by the Initial Purchaser expressly for use therein.

(b) The Initial Purchaser will indemnify and hold harmless the Sponsor and each person who controls the Sponsor within the meaning of Sections 15 of the Act and 20 of the Exchange Act against any losses, claims, damages or liabilities to which the Sponsor may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Registration Statement, any Issuer Free Writing Prospectus or the Prospectus, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in any Preliminary Prospectus, the Registration Statement, any Issuer Free Writing Prospectus or the Prospectus or any such amendment or supplement in reliance upon and in conformity with written information furnished to the Sponsor by the Initial Purchaser expressly for use therein; and will reimburse the Sponsor for any legal or other expenses reasonably incurred by the Sponsor in connection with investigating or defending any such action or claim as such expenses are incurred.

(c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under such subsection. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to,

- 12 -

any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

(d) If the indemnification provided for in this Section 10 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a) or (b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Sponsor and the Trust on the one hand and the Initial Purchaser on the other from the offering of the Purchased Shares. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under subsection (c) above, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Sponsor and the Trust on the one hand and the Initial Purchaser on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Sponsor and the Trust on the one hand and the Initial Purchaser on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Sponsor and the Trust bear to the excess of the total price at which the Purchased Shares are sold to the public by the Initial Purchaser over the value of the Initial Deposit (determined by multiplying the amount of the Initial Deposit by the LME Settlement Price announced on the date hereof). The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Sponsor and the Trust on the one hand or the Initial Purchaser on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Sponsor and the Initial Purchaser agree that it would not be just and equitable if contributions pursuant to this subsection (d) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above in this subsection (d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (d), the Initial Purchaser shall not be required to contribute any amount in excess of the amount by which the total price at which the Purchased Shares purchased by it and distributed to the public were offered to the public exceeds the amount of any damages which the Initial Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

- 13 -

(e) The obligations of the Sponsor under this Section 10 shall be in addition to any liability which the Sponsor may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls the Initial Purchaser within the meaning of the Act; and the obligations of the Initial Purchaser under this Section 10 shall be in addition to any liability which the Initial Purchaser may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Sponsor and to each person, if any, who controls the Sponsor or the Trust within the meaning of the Act.

11. The respective indemnities, agreements, representations, warranties and other statements of the Sponsor and the Initial Purchaser, as set forth in this Agreement or made by them pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of the Initial Purchaser or any controlling person of the Initial Purchaser, or the Sponsor, or any officer or director or controlling person of the Sponsor, and shall survive delivery of and payment for the Purchased Shares.

12. If any of the conditions set forth in Section 9 are not satisfied, and are not waived by the Initial Purchaser in its sole discretion, the obligations of the Initial Purchaser under this Agreement shall be subject to termination by the Initial Purchaser in its sole and absolute discretion no later than [7] calendar days after the effectiveness of the Registration Statement. If the Initial Purchaser shall elect to terminate this Agreement as provided in this Section 12, it shall notify the Sponsor promptly in writing. Upon a termination pursuant to this Section 12, (i) the Initial Purchaser shall have the absolute right to tender for redemption all of the Purchased Shares and receive redemption proceeds thereof valued at the net asset value per Purchased Share in accordance with the terms of the Shares, and, upon its exercise of such right, the Sponsor shall ensure that the Initial Purchaser shall have no liability, and shall not be subject to any deduction from its redemption proceeds, for costs, expenses or fees that otherwise may be incurred by a redeeming shareholder in connection with a redemption of Shares; and (ii) the Sponsor will reimburse the Initial Purchaser for all out of its pocket expenses, including fees and disbursements of counsel, reasonably incurred by the Initial Purchaser in making preparations for the purchase, sale and delivery of the Purchased Shares, but the Sponsor shall then be under no further liability to the Initial Purchaser except as provided in Sections 8 and 10 hereof and this Section 12.

13. All statements, requests, notices and agreements hereunder shall be in writing, and if to the Initial Purchaser shall be delivered or sent by mail, telex or facsimile transmission to the Initial Purchaser at [                    ], Attention: Registration Department; and if to the Sponsor shall be delivered or sent by mail to the address of the Sponsor set forth in the Registration Statement, Attention: Secretary; provided, however, that the information referred to in Section 6(e) shall be delivered to the Initial Purchaser via e-mail addressed to [e-mail address to be inserted]. Any such statements, requests, notices, agreements or information shall take effect upon receipt thereof.

14. This Agreement shall be binding upon, and inure solely to the benefit of, the Initial Purchaser, the Sponsor, the Trust and, to the extent provided in Sections 10 and 11 hereof, the officers and directors of the Sponsor and each person who controls the Sponsor, the Trust or the Initial Purchaser, and their respective heirs, executors, administrators, successors and assigns,

- 14 -

and no other person shall acquire or have any right under or by virtue of this Agreement. No purchaser of any of the Purchased Shares from the Initial Purchaser shall be deemed a successor or assign by reason merely of such purchase.

15. Time shall be of the essence of this Agreement. As used herein, the term “business day” shall mean any day when the Commission’s office in Washington, D.C. is open for business.

16. This Agreement shall be governed by and construed in accordance with the laws of the State of New York.

17. This Agreement may be executed by any one or more of the parties hereto in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same instrument

18. The Sponsor is authorized, subject to applicable law, to disclose any and all aspects of this potential transaction that are necessary to support any U.S. federal income tax benefits expected to be claimed with respect to such transaction, and all materials of any kind (including tax opinions and other tax analyses) related to those benefits, without the Initial Purchaser imposing any limitation of any kind.
