        Pursuant to the Letter of Transmittal, each holder of Outstanding Notes (a "Holder") will represent to the Company that (i) the Exchange Notes to be acquired pursuant to the Exchange Offer will be acquired in the ordinary course of business of the person acquiring the Exchange Notes, whether or not such person is the Holder, (ii) neither the Holder nor any person receiving any Exchange Notes directly or indirectly from the Holder pursuant to the Exchange Offer (if not a broker-dealer referred to in the last sentence of this paragraph) is engaging or intends to engage in the distribution of the Exchange Notes and none of them have any arrangement or understanding with any person to participate in the distribution of the Exchange Notes, (iii) the Holder and each person

receiving any Exchange Notes directly or indirectly from the Holder pursuant to the Exchange Offer acknowledge and agree that any person participating in the Exchange Offer for the purpose of distributing the Exchange Notes (x) must comply with the registration and prospectus delivery requirements of the Securities Act in connection with a secondary resale transaction of the Exchange Notes acquired by such person and (y) cannot rely on the position of the staff of the Securities and Exchange Commission (the "Commission") set forth in the Brown & Wood LLP no-action letter (available February 7, 1997), the Shearman & Sterling no-action letter (available July 2, 1993), the K-III Communications Corporation no-action letter (available May 14, 1993), the Morgan Stanley & Co., Incorporated no-action letter (available June 5, 1991) or the Exxon Capital Holdings Corporation no-action letter (available May 13, 1988) or similar letters, (iv) the Holder and each person receiving any Exchange Notes directly or indirectly from the Holder pursuant to the Exchange Offer understand that a secondary resale transaction described in clause (iii) above should be covered by an effective registration statement containing the selling security holder information required by Item 507 or 508, as applicable, of Regulation S-K of the Commission and (v) neither the Holder nor any person receiving any Exchange Notes directly or indirectly from the Holder pursuant to the Exchange Offer is an "affiliate" of the Company, as defined under Rule 405 under the Securities Act.
