In connection with all of the foregoing, the Trustees, solely in their capacities as trustees of the Trust, and the Depositor hereby constitute and appoint Gregory J. Pulles, James S. Broucek and Thomas F. Jasper, as his, her or its, as the case may be, true and lawful attorney-in-fact and agent with full power of substitution and resubstitution for the Depositor or in the Depositor's name, place and stead, in any and all capacities, to sign any and all amendments (including all pre-effective and post-effective amendments) to the Registration Statement and, if required, the Form 8-A and to file the same, with all exhibits thereto, and any other documents in connection therewith, with the Commission, granting unto said attorney-in-fact and agent full power and authority to do and perform each and every act and thing requisite and necessary to be done in connection therewith, as fully to all intents and purposes as the Depositor might or could do in person, hereby ratifying and confirming all that said attorney-in-fact and agent or her respective substitute or substitutes, shall do or cause to be done by virtue hereof.

6. The number of trustees of the Trust initially shall be three and thereafter the number of trustees of the Trust shall be such number as shall be fixed from time to time by a written instrument signed by the Depositor which may increase or decrease the number of trustees of the Trust; provided, however, that to the extent required by the Statutory Trust Act, one trustee of the Trust shall either be a natural person who is a resident of the State of Delaware or, if not a natural person, an entity which has its principal place of business in the State of Delaware. Subject to the foregoing, the Depositor is entitled to appoint or remove without cause any trustee of the Trust at any time. Any trustee of the Trust may resign upon thirty days' prior notice to the Depositor.

The Depositor hereby agrees, to the fullest extent permitted by applicable law, to (i) reimburse the Trustees for all reasonable expenses (including reasonable fees and expenses of counsel and other experts) and (ii) indemnify, defend and hold harmless the Trustees and any of the officers, directors, employees and agents of the Trustees (the "Indemnified Persons") from and against any and all losses, damages, liabilities, claims, actions, suits, costs, expenses, disbursements (including the reasonable fees and expenses of counsel), taxes and penalties of any kind and nature whatsoever (collectively, the "Expenses"), to the extent that such Expenses arise out of or are imposed upon or asserted at any time against such Indemnified Persons with respect to the performance of this Trust Agreement, the creation, operation or termination of the Trust or the transactions contemplated hereby; provided, however, that the Depositor shall not be required to indemnify any Indemnified Person for any Expenses which are a result of the willful misconduct, bad faith or gross negligence of such Indemnified Person.

8. This Trust Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware (with regard to conflict of laws principles).
