Item 15.  Indemnification

      Reference is made to the provisions of Article  Seventh of  Registrant's
Amended  and  Restated  Declaration  of  Trust,  filed by  cross-reference  to
Exhibit  16(1) to this  Registration  Statement,  and  incorporated  herein by
reference.

Insofar as  indemnification  for liabilities  arising under the Securities Act
of 1933 may be  permitted to trustees,  officers  and  controlling  persons of
Registrant pursuant to the foregoing  provisions or otherwise,  Registrant has
been advised  that in the opinion of the  Securities  and Exchange  Commission
such  indemnification  is against public policy as expressed in the Securities
Act of 1933 and is,  therefore,  unenforceable.  In the event that a claim for
indemnification   against  such   liabilities   (other  than  the  payment  by
Registrant of expenses  incurred or paid by a trustee,  officer or controlling
person  of  Registrant  in the  successful  defense  of any  action,  suit  or
proceeding)  is  asserted  by such  trustee,  officer or  controlling  person,
Registrant  will,  unless in the  opinion of its  counsel  the matter has been
settled  by   controlling   precedent,   submit  to  a  court  of  appropriate
jurisdiction  the  question  whether  such  indemnification  by it is  against
public policy as expressed in the  Securities Act of 1933 and will be governed
by the final adjudication of such issue.
