==============================================================================


     This Pre-Effective Amendment No. 1 to the Registrant's Registration
Statement on Form N-14 (File No. 333-57634) (the "Registration Statement")
consists of the following:

          (1) Facing Sheet of the Registration Statement,
          (2) Part C to the Registration Statement (including signature page),
     and

          (3) Exhibits 14(a), 14(b), 14(c), 14(d) and 14(e).

     Parts A and B are incorporated herein by reference from the Registration
Statement filed on March 26, 2001.

     This Pre-Effective Amendment No. 1 to the Registration Statement is being
filed solely to remove the delaying amendment that appeared on the facing
sheet of the Registration Statement filed on March 26, 2001.







                                    PART C

                               OTHER INFORMATION

Item 15.      Indemnification.

     Reference is made to Article VI of the Registrant's Articles of
Incorporation, Article VI of the Registrant's By-Laws, Section 2-418 of the
Maryland General Corporation Law and Section 9 of the Class A, Class B, Class
C and Class D Distribution Agreements.

     Insofar as the conditional advancing of indemnification moneys for
actions based on the Investment Company Act of 1940, as amended (the
"Investment Company Act"), may be concerned, Article VI of the Registrant's
By-Laws provides that such payments will be made only on the following
conditions: (i) advances may be made only on receipt of a written affirmation
of such person's good faith belief that the standard of conduct necessary for
indemnification has been met and a written undertaking to repay any such
advance if it is ultimately determined that the standard of conduct has not
been met; and (ii) (a) such promise must be secured by a security for the
undertaking in form and amount acceptable to the Registrant, (b) the
Registrant is insured against losses arising by receipt by the advance, or (c)
a majority of a quorum of the Registrant's disinterested non-party Directors,
or an independent legal counsel in a written opinion, shall determine, based
upon a review of readily available facts, that at the time the advance is
proposed to be made, there is reason to believe that the person seeking
indemnification will ultimately be found to be entitled to indemnification.

     In Section 9 of the Class A, Class B, Class C and Class D Shares
Distribution Agreements relating to the securities being offered hereby, the
Registrant agrees to indemnify the FAM Distributors, Inc (the "Distributor")
and each person, if any, who controls the Distributor within the meaning o the
Securities Act of 1933, as amended (the "Securities Act"), against certain
types of civil liabilities arising in connection with the Registration
Statement or Prospectus and Statement of Additional Information.

     Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to Directors, officers and controlling persons of the
Registrant and the principal underwriter 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 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 and the principal underwriter
in connection with the successful defense of any action, suit or proceeding)
is asserted by such Director, officer or controlling person or the principal
underwriter in connection with the shares 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 and will be governed by the final adjudication
of such issue.
