The Registrants are registering the Exchange Notes on the Registration Statement in reliance on the position of the Securities and Exchange Commission (the “Commission”) enunciated in Exxon Capital Holdings Corporation, available May 13, 1988 (“Exxon Capital”), Morgan Stanley & Co. Incorporated, available June 5, 1991 (regarding resales) and Shearman & Sterling, available July 2, 1993 (with respect to the participation of broker-dealers). The Registrants hereby make the following representations to the Staff of the Commission:

1. The Registrants have not entered into any arrangement or understanding with any person to distribute the Exchange Notes and, to the best of each of the Registrants’ information and belief without independent investigation, each person participating in the exchange offers is acquiring the Exchange Notes in its ordinary course of business and is not engaged in, does not intend to engage in, and has no arrangement or understanding with any person to participate in, the distribution of the Exchange Notes. In this regard, the Registrants will disclose to each person participating in the exchange offers that if such person is participating in the exchange offers for the purpose of distributing the Exchange Notes, such person (i) could not rely on the Staff position enunciated in Exxon Capital or interpretive letters to similar effect and (ii) must comply with registration and prospectus delivery requirements of the Securities Act in connection with a secondary resale

transaction. Each Registrant acknowledges that such a secondary resale transaction by such person participating in the exchange offers for the purpose of distributing the Exchange Notes should be covered by an effective registration statement containing the selling securityholder information required by Item 507 of Regulation S-K.

2. No broker-dealer has entered into any arrangement or understanding with the Registrants or an affiliate of the Registrants to distribute the Exchange Notes. The Registrants will disclose to each person participating in the exchange offers (through the exchange offer prospectus) that any broker-dealer who receives the Exchange Notes for its own account pursuant to the exchange offers may be a statutory underwriter and must deliver a prospectus meeting the requirements of the Securities Act in connection with any resale of those Exchange Notes. The Registrant will also include in the letter of transmittal to be executed by each holder participating in the exchange offers that each broker-dealer that receives the Exchange Notes for its own account pursuant to the exchange offers must acknowledge that it will deliver a prospectus meeting the requirements of the Securities Act in connection with any resale of those Exchange Notes and that by so acknowledging and delivering a prospectus, the broker-dealer will not be deemed to admit that it is an “underwriter” within the meaning of the Securities Act.

If you have any questions on the above-referenced Registration Statement, please contact Richard A. Fenyes of Simpson Thacher & Bartlett LLP at (212) 455-2812.


Very truly yours,
