the Securities Act of 1933 or until the Registration Statement shall become
effective on such date as the Securities and Exchange Commission, acting
pursuant to Section 8(a), may determine. Parts A and B of Registrant's
Registration Statement under the Securities Act of 1933 on Form N-14, filed on

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; and

                      (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 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


                                      C-2


               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) 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

        initial bona fide offering of them.
