 WHEREAS: 
  
 A. The Company entered into
the First Amended and Restated Registration Rights Agreement (the “Agreement”), dated as of August 5, 2005, with the Purchaser and additional parties collectively defined therein as “Buyers”; 
  
 B. The Agreement requires the Company to file a “Registration
Statement” by the “Filing Deadline” as such terms are defined in Sections 1(k) and 1(f), respectively, of the Agreement; and 
  
 C. The Company and the Purchaser wish to amend the definition of the Filing Deadline as set forth in the Agreement and the Purchaser is willing to
waive any failure of the Company to file the Registration Statement by the Filing Deadline as defined in the original Agreement. 
  
 NOW, THEREFORE, in consideration of the premises and the mutual covenants contained herein and for other good and valuable consideration the receipt and
sufficiency of which is hereby acknowledged, the Company and the Purchaser hereby agree as follows: 
  
 1. Definitions. All capitalized terms used herein that are not defined in this Amendment shall have the meanings given such terms in the Agreement.

  
 2. Amendment. Section 1 (f) of the Agreement
is hereby amended and restated in its entirety to read as follows: 
  
 ““Filing Deadline” means September 12, 2005.” 
  
 3. Waiver. The Purchaser hereby waives (a) the Company’s failure prior to the date hereof to file the Registration Statement by the
Filing Deadline (as defined in the Agreement prior to this Amendment) as required by the Agreement and (b) the right to receive any Registration Delay Payments that are due and payable as of the date hereby pursuant to the terms of the
Registration Rights Agreement and any Event of Default that would arise under the Amended Note solely as a result of the failure to make any such Registration Delay Payment. 
  
 4. Remaining Terms. Except as specifically amended or waived by this Amendment, all of the terms and conditions of
the Agreement shall remain unmodified and in full force and effect. 
  
 5. Effectiveness. This Amendment shall become effective when executed by the Company and those Buyers that constitute the Required Holders as defined in Section 1(l) of the Agreement and shall be binding on and inure to the
benefit of the Company and all Buyers, notwithstanding the fact that some Buyers may not have executed this Amendment. 
  
 6. Miscellaneous. 
  
 a. This Amendment may be executed in two or more identical counterparts, all of which shall be considered one and the same agreement and shall become
effective when counterpart signature pages have been signed by each party and delivered to the other parties; provided that the parties need not sign the same counterpart signature page and a facsimile signature shall be considered due execution and
shall be binding upon the signatory thereto with the same force and effect as if the signature were an original. 







 b. The headings of this Amendment are for convenience of reference and shall not form part of, or affect
the interpretation of, this Amendment. 
  
 c. If any provision of
this Amendment shall be invalid or unenforceable in any jurisdiction, such invalidity or unenforceability shall not affect the validity or enforceability of the remainder of this Agreement in that jurisdiction or the validity or enforceability of
any provision of this Agreement in any other jurisdiction. 
  
 d.
This Amendment is intended for the benefit of the parties hereto and their respective permitted successors and assigns, and, subject to the provisions of Section 5 above, is not for the benefit of, nor may any provision hereof be enforced by,
