      As you requested, the undersigned hereby acknowledges that:

* should the Securities and Exchange Commission (the "Commission") or the staff
of the Commission (the "Staff"), acting pursuant to delegated authority,
declare the filing effective, it does not foreclose the Commission from taking

* the action of the Commission or the Staff, acting pursuant to delegated
authority, in declaring the filing effective, does not relieve the undersigned
from its full responsibility for the adequacy and accuracy of the disclosure in
the filing; and

* the undersigned may not assert Staff comments and the declaration of
effectiveness as a defense in any proceeding initiated by the Commission or any
person under the federal securities laws of the United States.


If you have any questions, please contact Virginia Pappas, Esq., Associate
General Counsel, at (215) 986-4058.


                                            Sincerely,
