ITEM 4.  Description of Securities.

         Not Applicable.


Item 5.  Interest of Named Experts and Counsel.

         Not Applicable.


Item 6.  Indemnification of Directors and Officers

         Section 722 of the New York Business Corporation Law ("NYBCL") permits,
in general, a New York corporation to indemnify any person made, or threatened
to be made, a party to an action or proceeding by reason of the fact that he or


                                       2



she was a director or officer of the corporation, or served another entity in
any capacity at the request of the corporation, against any judgment, fines,
amounts paid in settlement and reasonable expenses, including attorney's fees
actually and necessarily incurred as a result of such action or proceeding, or
any appeal therein, if such person acted in good faith, for a purpose he or she
reasonably believed to be in, or, in the case of service for another entity, not
opposed to, the best interests of the corporation and, in criminal actions or
proceedings, in addition had no reasonable cause to believe that his or her
conduct was unlawful. Section 723 of the NYBCL permits the corporation to pay in
advance of a final disposition of such action or proceeding the expenses
incurred in defending such action or proceeding upon receipt of an undertaking
by or on behalf of the director or officer to repay such amount as, and to the
extent, required by statute. Section 721 of the NYBCL provides that
indemnification and advancement of expense provisions contained in the NYBCL
shall not be deemed exclusive of any rights to which a director or officer
seeking indemnification or advancement of expenses may be entitled, provided no
indemnification may be made on behalf of any director or officer if a judgment
or other final adjudication adverse to the director or officer establishes that
his or her acts were committed in bad faith or were the result of active or
deliberate dishonesty and were material to the cause of action so adjudicated,
or that he or she personally gained in fact a financial profit or other
advantage to which he or she was not legally entitled.

         Article Seventh of the Registrant's Certificate of Incorporation
provides, in general, that the Registrant may indemnify, to the fullest extent
permitted by applicable law, every person threatened to be made a party to any
action, suit or proceeding by reason of the fact that such person is or was an
officer or director or was serving at the request of the Registrant as a
director, officer, employee, agent or trustee of another corporation, business,
partnership, joint venture, trust, employee benefit plan, or other enterprise,
against expenses, judgments, fines and amounts paid in settlement in connection
with such suit or proceeding. Article Seventh of the Certificate of
Incorporation also provides that the Registrant may indemnify and advance
expenses to those persons as authorized by resolutions of a majority of the
Board of Directors or shareholders, agreement, directors' or officers' liability
insurance policies, or any other form of indemnification agreement.

         In accordance with that provision of the Certificate of Incorporation,
the Registrant shall indemnify any officer or director (including officers and
directors serving another corporation, partnership, joint venture, trust,
employee benefit plan or other enterprise in any capacity at the Registrant's
request) made, or threatened to be made, a party to an action or proceeding
(whether civil, criminal, administrative or investigative) by reason of the fact
that he or she was serving in any of those capacities against judgments, fines,
amounts paid in settlement and reasonable expenses (including attorney's fees)
incurred as a result of such action or proceeding. Indemnification would not be
available under Article Seventh of the Certificate of Incorporation if a
judgment or other final adjudication adverse to such director or officer
establishes that (i) his or her acts were committed in bad faith or were the
result of active and deliberate dishonesty and, in either case, were material to
the cause of action so adjudicated, or (ii) he or she personally gained in fact
a financial profit or other advantage to which he or she was not legally
entitled. Article Seventh of the Certificate of Incorporation further stipulates
that the rights granted therein are contractual in nature.

         At present, there is no pending litigation or other proceeding
involving a director or officer of the Registrant as to which indemnification is
being sought, nor is the Registrant aware of any threatened litigation that may
result in claims for indemnification by any officer or director.


Item 7.  Exemption From Registration Claimed.

         Not Applicable.

Item 9. Undertakings

(a)     The undersigned Registrant hereby undertakes:

         (1) To file, during any period in which offers or sales are being made,
a post-effective amendment to this registration statement:

                  (iii) To include any material information with respect to the
plan of distribution not previously disclosed in the registration statement or
any material change to such information in the registration statement.

         (2) That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

         (3) To remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the termination of
the offering.

(b)      The undersigned registrant hereby undertakes that, for purposes of
         determining any liability under the Securities Act of 1933, each filing
         of the registrant's annual report pursuant to section 13(a) or section
         15(d) of the Securities Exchange Act of 1934 that is incorporated by
         reference in the registration statement shall be deemed to be a new
         registration statement relating to the securities offered therein, and
         the offering of such securities at that time shall be deemed to be the
         initial bona fide offering thereof.

(h)      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 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 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


                                       4


         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.
