PART C - OTHER INFORMATION

ITEM 15.  INDEMNIFICATION.

     Section 2-418 of the Maryland General Corporation Law ("MGCL") permits
indemnification of a director against judgments, penalties, fines, settlements
and reasonable expenses actually incurred by the director in connection with any
proceeding to which he has been made a party by reason of service as a director,
unless it is established that (i) the director's act or omission was material to
the matter giving rise to the proceeding and was committed in bad faith or was
the result of active and deliberate dishonesty; or (ii) the director actually
received an improper personal benefit in money, property or services; or (iii)
in the case of a criminal proceeding, the director had reasonable cause to
believe that the act or omission was unlawful. However, indemnification may not
be made in any proceeding by or in the right of the corporation in which the
director has been adjudged to be liable to the corporation. In addition, a
director may not be indemnified in respect of any proceeding charging improper
personal benefit to the director, whether or not involving action in the
director's official capacity, in which the director was adjudged to be liable on
the basis that personal benefit was improperly received. Section 2-418 of the
MGCL also requires a corporation, unless limited by its charter, to indemnify a
director who has been successful in the defense of a proceeding against
reasonable expenses incurred. Reasonable expenses incurred by a director may be
paid or reimbursed by a corporation in advance of the final disposition of a
proceeding upon the receipt of certain written affirmations and undertakings
required by Section 2-418. Unless limited by its Charter, a Maryland corporation
(i) may indemnify and advance expenses to an officer to the same extent it may
indemnify a director, (ii) is required to indemnify an officer to the extent
required for a director, and (iii) may indemnify and advance expenses to an
officer who is not a director to such further extent, consistent with law, as
provided by the charter, bylaws, action of its board of directors or contract.

     See Article V of the Registrant's Amended and Restated Bylaws dated May 8,
2003, which Bylaws are incorporated herein by reference to Post-Effective
Amendment No. 36 to the Registration Statement on Form N-1A, filed on February
4, 2004 (File No. 2-80751).

     See Section 7 of the Registrant's Amended and Restated Distribution
Agreement dated November 3, 2004, which Agreement is incorporated herein by
reference to Post-Effective Amendment No. 41 to the Registration Statement on
Form N-1A, filed on April 29, 2005 (File No. 2-80751).

     See Section 14 of the Registrant's Transfer Agency Agreement dated April
28, 2003, which Agreement is incorporated herein by reference to Post-Effective
Amendment No. 38 to the Registration Statement on Form N-1A, filed on April 29,
2004 (File No. 2-80751).

     The Registrant, at its expense, provides liability insurance for the
benefit of its directors and officers.

                                      -1-



     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing, 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 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 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 Act and will be governed by the final adjudication of
such issue.

this registration statement by any person or party who is deemed to be an

amended (the "1933 Act"), the reoffering prospectus will contain the information

to be the initial bona fide offering of them.
