Indemnification and Contribution.

(a) The Sponsor and the Trust will jointly and severally indemnify and hold harmless the Seed Capital Investor against any losses, claims, damages or liabilities, joint or several, to which the Seed Capital Investor 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 the Registration Statement 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, in the light of the circumstances under which they were made, not misleading, and will reimburse the Seed Capital Investor for any legal or other expenses reasonably incurred by the Seed Capital Investor in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that neither the Sponsor nor the Trust shall 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 the Registration Statement or the Prospectus or any such amendment or supplement in reliance upon and in conformity with written information furnished to the Sponsor by the Seed Capital Investor expressly for use therein.

(b) The Seed Capital Investor will indemnify and hold harmless the Sponsor and the Trust against any losses, claims, damages or liabilities to which the Sponsor or the Trust may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities

- 3 -

(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 the Registration Statement 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, in the light of the circumstances under which they were made, 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 the Registration Statement or the Prospectus or any such amendment or supplement in reliance upon and in conformity with written information furnished to the Sponsor by the Seed Capital Investor expressly for use therein; and will reimburse the Sponsor and the Trust 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, 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, 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 4 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 Seed Capital Investor on the other from the offering of the Shares in controversy comprising the Aggregate Seed Baskets. 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

- 4 -

hand and the Seed Capital Investor 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 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 or the Trust on the one hand or the Seed Capital Investor on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Sponsor, the Trust and the Seed Capital Investor agree that it would not be just and equitable if contribution 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 Seed Capital Investor shall not be required to contribute any amount in excess of the amount by which the total price at which the Shares in controversy comprising the Aggregate Seed Baskets purchased by it and distributed to the public were offered to the public exceeds the amount of any damages which the Seed Capital Investor 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.

(e) The obligations of the Sponsor under this Section 4 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 Seed Capital Investor within the meaning of the Act; and the obligations of the Seed Capital Investor under this Section 4 shall be in addition to any liability which the Seed Capital Investor 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 within the meaning of the Act.

5. The respective indemnities, agreements, representations, warranties and other statements of the Sponsor and the Seed Capital Investor, 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 Seed Capital Investor or any controlling person of the Seed Capital Investor, or the Sponsor, or any officer or director or controlling person of the Sponsor, and shall survive delivery of and payment for the Shares comprising the Aggregate Seed Baskets.

6. If the Shares comprising the Aggregate Seed Baskets are not delivered by or on behalf of the Sponsor or the Trust as provided herein, the Sponsor and the Trust will reimburse the Seed Capital Investor for all out-of-pocket expenses, including fees and disbursements of counsel, reasonably incurred by the Seed Capital Investor in making preparations for the purchase, sale and delivery of the Shares comprising the Aggregate Seed Baskets, but the Sponsor and the Trust shall then be under no further liability to the Seed Capital Investor except as provided in Section 5 hereof.

All statements, requests, notices and agreements hereunder shall be in writing, and

- 5 -

if to the Seed Capital Investor shall be delivered or sent by mail to the Seed Capital Investor at 50 Hudson Yards, New York, New York 10001 and if to the Sponsor or the Trust shall be delivered or sent by mail to the address of the Sponsor set forth in the Registration Statement, Attention: Product Management Team, iShares Product Research & Development. Any such statements, requests, notices or agreements shall take effect upon receipt thereof.

8. This Agreement shall be binding upon, and inure solely to the benefit of, the Seed Capital Investor, the Sponsor, the Trust and, to the extent provided in Sections 5 and 6 hereof, the officers and directors of the Sponsor and the Trust and each person who controls the Sponsor or the Seed Capital Investor, and their respective heirs, executors, administrators, successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement. No purchaser of any of the Shares comprising the Aggregate Seed Baskets from the Seed Capital Investor shall be deemed a successor or assign by reason merely of such purchase.

9. As used herein, the term “business day” shall mean any day when the Commission’s office in Washington, D.C. is open for business.

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

11. 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.

12. The Sponsor and the Trust are 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 Seed Capital Investor imposing any limitation of any kind.
