      thereto and General Electric Capital Corporation, a Delaware corporation
      (&#147;<u>GE Capital</u>&#148;), for itself, as Lender, and as Agent for
      Lenders (in such capacity, the &#147;<u>Agent</u>&#148;). Capitalized terms
      used herein and not defined herein have the meanings assigned to them in
      the Credit Agreement.</font></p>
  <p align="justify"><font size="2" face="serif">You have requested that we extend
      the Commitment Termination Date from September 14, 2001 until November
      15, 2004 and we hereby agree to such extension so long as upon your acceptance
      of this consentwe receive the remaining 50% of the success fee, in an amount
      equal to $150,000, payable to the Lenders pursuant to that certain Eighth
      Amendment to Credit Agreement dated as of June 16, 2004, by and among the
      Borrower, the other Credit Parties, the Lenders and the Agent. </font></p>
  <p align="justify"><font size="2" face="serif">You hereby acknowledge that you
      are actively seeking an extension of the maturity date of the Subordinated
      Notes beyond December 31, 2004. Additionally you acknowledge and agree
      that regardless of whether or not any such extensions are executed, GE
      Capital has not issued, does not have, and the consummation of any such
      extensions does not create, any commitment of GE Capital to extend the
      Commitment Termination Date beyond November 15, 2004.</font></p>
  <p align="justify"><font size="2" face="serif">If the foregoing is acceptable
      to you, kindly evidence your acceptance of and agreement to the foregoing,
      by signing and returning to GE Capital at least two (2) original counterparts
      of this letter agreement.</font></p>
  <p align="justify"><font size="2" face="serif">The consent set forth herein is
      limited to the matters expressly set forth herein and shall not be deemed
      to waive or modify any term of the Credit Agreement or any of the other
      Credit Documents or serve as a consent to any other matters prohibited
      by the terms and conditions thereof. This letter agreement and the rights
      and obligations of the parties hereunder shall be construed in accordance
      with and be governed by the law (without giving effect to the conflict
      of law principles thereof) of the State of New York.</font></p>
