(“POI Acquisition”); and (b) letter from Quadrangle Master Funding Ltd (“Quadrangle”) to POAM, dated February 27, 2004:  (i) advising POAM of Quadrangle’s assumption from POI Acquisition of one-third of the obligations under the Credit Facility; and (ii) confirming Quadrangle’s agreement to be bound by the obligations of POI Acquisition set forth in the Agreement.  Capitalized terms used but not defined herein shall have the meanings ascribed to such terms in the Agreement.

Pursuant to section 3 of the Agreement, the Agreement shall terminate and be of no further force and effect on the Debt Specified Date (which, under clause (i), is May 17, 2004).  By this letter and at your request, we hereby agree to amend the definition of the Outside Date to mean the date that is 97 days after the Effective Time (the “Amendment”); provided, however, that this Amendment shall not apply to section 5 of the Agreement.  Except as otherwise provided herein, the Agreement shall remain in full force and effect subject to the terms and provisions thereof.
