                              STATEMENT OF PURPOSE

      Pursuant to that  certain  Credit  Agreement  dated as of May 27, 2005 (as
amended,  restated,  supplemented or otherwise modified, the "CREDIT Agreement")
by and among the Borrower, the Lenders and the Administrative Agent, the Lenders
have  agreed  to make,  and have  made,  certain  extensions  of  credit  to the
Borrower.

      The Borrower has requested that the Lenders amend the Credit  Agreement as
provided  herein.  Subject to the terms and  conditions  set forth  herein,  the
Lenders are willing to consent to such amendment.

      NOW,  THEREFORE,  for good and  valuable  consideration,  the  receipt and
sufficiency of which are hereby acknowledged by the parties hereto, such parties
hereby agree as follows:

      SECTION 1. DEFINITIONS.  All capitalized terms used and not defined herein
shall have the meanings assigned thereto in the Credit Agreement.

      SECTION 2. AMENDMENTS.  (a) SECTION 1.01 of the Credit Agreement ("Defined
Terms") is hereby  amended by deleting the definition  for  "Consolidated  Fixed
Charge  Coverage  Ratio" and  substituting  in lieu  thereof the  following  new
definition, to read in its entirety as follows:

            "CONSOLIDATED  FIXED CHARGE COVERAGE RATIO" means, as of any date of
      determination,  the ratio of (a) Consolidated  EBITDAR minus taxes paid or
      payable in cash,  minus  dividends and other  distributions  paid in cash,
      minus amounts paid to  repurchase,  redeem or otherwise  acquire shares of
      the  Borrower's  Capital Stock for the period of the four fiscal  quarters
      most recently ended to (b) Consolidated Fixed Charges for such period.

      (b) SECTION 7.06 of the Credit  Agreement is hereby  amended by adding the
following subsection (f) thereto:

            (f) the Borrower may repurchase,  redeem or otherwise acquire shares
      of its Capital Stock from its stockholders;  provided, that (i) no Default
      or Event of Default shall exist or result therefrom, and (ii) after giving
      pro forma effect to any such payments,  the Borrower shall be in pro forma
      compliance with SECTION 7.11.

      SECTION 3.  EFFECTIVENESS.  This Amendment  shall become  effective on the
date that the  Administrative  Agent shall have received  satisfactory  evidence
that this Amendment has been duly executed and delivered by the Borrower and the
Lenders.

      SECTION 4. LIMITED EFFECT. Except as expressly provided in this Amendment,
the Credit  Agreement  and each other Loan  Document  shall  continue to be, and

amendment  of, any other term or condition of the Credit  Agreement or any other
Loan  Document,   (b)  to  prejudice  any  other  right  or  remedies  that  the
Administrative Agent or the Lenders, or any of them, may now have or may have in
the  future  under  or in  connection  with  the  Credit  Agreement  or the Loan
Documents, as such documents may be amended, restated or otherwise modified from
time to time, or (c) to be a commitment or any other  undertaking  or expression
of any willingness to engage in any further  discussion with the Borrower or any
other  person,  firm or  corporation  with  respect  to any  waiver,  amendment,
modification  or any other change to the Credit  Agreement or the Loan Documents
or any rights or remedies arising in favor of the Lenders or the  Administrative
Agent, or any of them,  under or with respect to any such documents.  References

Agreement  and the other Loan  Documents  is true and  correct  in all  material

representations and warranties which speak as of a specific date pursuant to the
Credit Agreement,  which representations and warranties shall have been true and
correct in all material  respects as of such specific  dates) and that as of the
date hereof no Default or Event of Default has occurred and is continuing, and

      (b) the  execution,  delivery and  performance of this Amendment have been
