behalf of the Trust by the Trustees, the Trustees, in their capacity as trustees
of the Trust, are hereby authorized to join in any such filing and to execute on
behalf of the Trust any and all of the foregoing, it being understood that the

unless required by the rules and regulations of the Commission, PORTAL or state
securities or "Blue Sky" laws.

         5. This Declaration of Trust may be executed in one or more
counterparts.

         6. The number of Trustees of the Trust initially shall be four and
thereafter the number of trustees of the Trust shall be such number as shall be

may increase or decrease the number of trustees of the Trust; provided, however,

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. The
Delaware Trustee may resign upon thirty days' prior notice to the Depositor.

laws principles).
