number as shall be fixed from time to time by a written instrument signed by the
Sponsor, which may increase or decrease the number of trustees of the Issuer
Trust; provided, however, that, to the extent required by the Business Trust
Act, one trustee of the Issuer 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
