PART C:  OTHER INFORMATION

Item 15:  Indemnification

         Section 5.3 of the Registrant's Declaration of Trust provides as
follows:

                   (a) Subject to the exceptions and limitations contained in
paragraph (b) below:

                           (i) every person who is or has been a Trustee or
                  officer of the Trust (hereinafter referred to as a "Covered
                  Person") shall be indemnified by the Trust against all
                  liability and against all expenses reasonably incurred or paid
                  by him or her in connection with any claim, action, suit or
                  proceeding in which that individual becomes involved as a
                  party or otherwise by virtue of being or having been a Trustee
                  or officer and against amounts paid or incurred by that
                  individual in the settlement thereof;

                           (ii) the words "claim," "action," "suit" or
                  "proceeding" shall apply to all claims, actions, suits or
                  proceedings (civil, criminal, administrative or other,
                  including appeals), actual or threatened; and the words
                  "liability" and "expenses" shall include, without limitation,
                  attorneys' fees, costs, judgments, amounts paid in settlement
                  or compromise, fines, penalties and other liabilities.

                   (b) No indemnification shall be provided hereunder to a
Covered Person:

                           (i) against any liability to the Trust or the
                  Shareholders by reason of a final adjudication by the court or
                  other body before which the proceeding was brought that the
                  Covered Person engaged in willful misfeasance, bad faith,
                  gross negligence or reckless disregard of the duties involved
                  in the conduct of that individual's office;

                           (ii) with respect to any matter as to which the
                  Covered Person shall have been finally adjudicated not to have
                  acted in good faith in the reasonable belief that that
                  individual's action was in the best interest of the Trust; or

                           (iii) in the event of a settlement involving a
                  payment by a Trustee or officer or other disposition not
                  involving a final adjudication as provided in paragraph (b)(i)
                  or (b)(ii) above resulting in a payment by a Covered Person,
                  unless there has been either a determination that such Covered
                  Person did not engage in willful misfeasance, bad faith, gross
                  negligence or reckless disregard of the duties involved in the

                                      C-1

                  conduct of that individual's office by the court or other body
                  approving the settlement or other disposition or by a
                  reasonable determination, based upon a review of readily
                  available facts (as opposed to a full trial-type inquiry) that
                  that individual did not engage in such conduct:

                                     (A) by vote of a majority of the
                           Disinterested Trustees (as defined below) acting on
                           the matter (provided that a majority of the
                           Disinterested Trustees then in office act on the
                           matter); or

                                     (B) by written opinion of (i) the
                           then-current legal counsel to the Trustees who are
                           not Interested Persons of the Trust or (ii) other
                           legal counsel chosen by a majority of the
                           Disinterested Trustees (or if there are no
                           Disinterested Trustees with respect to the matter in
                           question, by a majority of the Trustees who are not
                           Interested Persons of the Trust) and determined by
                           them in their reasonable judgment to be independent.

                   (c) The rights of indemnification herein provided may be
         insured against by policies maintained by the Trust, shall be
         severable, shall not affect any other rights to which any Covered
         Person may now or hereafter be entitled, shall continue as to a person
         who has ceased to be a Covered Person and shall inure to the benefit of
         the heirs, executors and administrators of such person. Nothing
         contained herein shall limit the Trust from entering into other
         insurance arrangements or affect any rights to indemnification to which
         Trust personnel, including Covered Persons, may be entitled by contract
         or otherwise under law.

                   (d) Expenses of preparation and presentation of a defense to
         any claim, action, suit, or proceeding of the character described in
         paragraph (a) of this Section 5.3 shall be advanced by the Trust prior
         to final disposition thereof upon receipt of an undertaking by or on
         behalf of the Covered Person to repay such amount if it is ultimately
         determined that the Covered Person is not entitled to indemnification
         under this Section 5.3, provided that either:

                           (i) such undertaking is secured by a surety bond or
                  some other appropriate security or the Trust shall be insured
                  against losses arising out of any such advances; or

                           (ii) a majority of the Disinterested Trustees acting
                  on the matter (provided that a majority of the Disinterested
                  Trustees then in office act on the matter) or legal counsel
                  meeting the requirement in Section 5.3(b)(iii)(B) above in a
                  written opinion, shall determine, based upon a review of
                  readily available facts (as opposed to a full trial-type
                  inquiry), that there is reason to believe that the Covered
                  Person ultimately will be found entitled to indemnification.

                  As used in this Section 5.3, a "Disinterested Trustee" is one
                  (i) who is not an "Interested Person" of the Trust (including
                  anyone who has been exempted from being an "Interested Person"
                  by any rule, regulation or order of the Commission), and (ii)

                                      C-2

                  against whom none of such actions, suits or other proceedings
                  or another action, suit or other proceeding on the same or
                  similar grounds is then or had been pending.

                   (e) With respect to any such determination or opinion
         referred to in clause (b)(iii) above or clause (d)(ii) above, a
         rebuttable presumption shall be afforded that the Covered Person has
         not engaged in willful misfeasance, bad faith, gross negligence or
         reckless disregard of the duties involved in the conduct of such
         Covered Person's office in accordance with pronouncements of the
         Commission.

         Insofar as indemnification for liability arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the Registrant pursuant to the foregoing provisions, or otherwise, the
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
the Registrant of expenses incurred or paid by a director, officer or
controlling person of the Registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the 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.

Item 17:  Undertakings

                   (1) The undersigned Registrant agrees that prior to any
         public reoffering of the securities registered through the use of a
         prospectus which is a part of this Registration Statement by any person
         or party who is deemed to be an underwriter within the meaning of Rule
         145(c) of the Securities Act [17 CFR 230.15c], the reoffering
         prospectus will contain the information called for by the applicable
         registration form for reofferings by persons who may be deemed
         underwriters, in addition to the information called for by the other
         items of the applicable form.

                   (2) The undersigned Registrant agrees that every prospectus
         that is filed under paragraph (1) above will be filed as a part of an

         amendment is effective, and that, in determining any liability under
         the 1933 Act, each post-effective amendment shall be deemed to be a new
         registration statement for the securities offered therein, and the
         offering of the securities at that time shall be deemed to be the
         initial bona fide offering of them.
