Ladies and Gentlemen:

     In regard to the above-referenced  Registration Statement,  and pursuant to
Rule 461  under the  Securities  Act of 1933,  the  registrant  hereby  requests
acceleration  of the  effective  date  to 2 PM on  June  14,  2006  or as  soon

Further, the registrant hereby acknowledges that:

     *    Should the  Commission  or the staff,  acting  pursuant  to  delegated
          authority,  declare the filing  effective,  it does not  foreclose the
          Commission from taking any action with respect to the filing;

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

     *    The company  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.

     Please  contact our counsel,  Eugene M. Cronin,  Esq. at Dolgenos  Newman &
