the Registrant pursuant to the foregoing provisions, the Registrant has been
informed that in the opinion of the Securities and Exchange Commission, such
indemnification is against public policy as expressed in the Act and is

Item 9.  Undertakings.

     The undersigned registrant hereby undertakes as follows:

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

          (i)   To include any prospectus required by Section
              10(a)(3) of the Securities Act of 1933;

          (ii)  To reflect in the prospectus any facts or events arising after
     the effective date of the registration statement (or the most recent
     post-effective amendment thereof) which, individually or in aggregate,
     represent a fundamental change in the information set forth in this





                                       3

<PAGE>   4

         registration statement;

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

provided, however, that the undertaking set forth in paragraphs (i) and (ii)
above do not apply if that information required to be included in a
post-effective amendment by those paragraphs is contained in periodic reports
filed by the Registrant pursuant to Section 13 or Section 15(d) of the
Securities Exchange Act of 1934 that are incorporated by reference in this
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.

     (4)  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(a) of the Securities Exchange Act of 1934 (and where
applicable, each filing of an employee benefit plan's annual report pursuant to
Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by
reference in this 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.

     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
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 jurisdiction of
such issue.

     The legality of the Common Stock offered hereby has been passed upon for

the Registrant pursuant to the foregoing provisions, the Registrant has been
informed that in the opinion of the Securities and Exchange Commission, such
indemnification is against public policy as expressed in the Act and is

                               of the securities being registered.

       23(a)                   Consent of Price Waterhouse LLP

       23(b)                   Consent of Satterlee Stephens Burke

                               as Exhibit 5 hereto).
Item 9.  Undertakings.

     The undersigned registrant hereby undertakes as follows:

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

          (i)   To include any prospectus required by Section
              10(a)(3) of the Securities Act of 1933;

          (ii)  To reflect in the prospectus any facts or events arising after
     the effective date of the registration statement (or the most recent
     post-effective amendment thereof) which, individually or in aggregate,
     represent a fundamental change in the information set forth in this

                                       3
4

         registration statement;

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

provided, however, that the undertaking set forth in paragraphs (i) and (ii)
above do not apply if that information required to be included in a
post-effective amendment by those paragraphs is contained in periodic reports
filed by the Registrant pursuant to Section 13 or Section 15(d) of the
Securities Exchange Act of 1934 that are incorporated by reference in this
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.

     (4)  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(a) of the Securities Exchange Act of 1934 (and where
applicable, each filing of an employee benefit plan's annual report pursuant to
Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by
reference in this 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.

     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
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 jurisdiction of
such issue.
