Set forth below are the Co-Issuers’ responses to the Staff’s comments. Concurrently with the filing of this letter, the Co-Issuers are submitting (via EDGAR) Amendment No. 2 to the Registration Statement on Form S-4/A, which reflects changes made to the Registration Statement in response to the Staff’s comments.

officer, principal financial officer, controller or principal accounting officer, and at least a majority of the board of directors for each of the guarantors. Please revise the signatures to have each of these officers and a majority of the board sign the registration statement. See Instruction 1 to Signatures on Form S-4.

Response: The Company has revised the signature pages of the Registration Statement as requested.

Exhibit 5.5

2. We note the assumptions contained in paragraphs (e), (g), (h), (i), and (j). Please either remove these assumptions or advise us why counsel needs to assume these matters for purposes of rendering its opinion. In particular, the assumption in paragraph (e) is inappropriate in that it subsumes the opinion being provided by counsel. With respect to the other assumptions, it appears that these matters may be determined by diligence of counsel. Please advise or revise as appropriate.

Response: The assumptions contained in paragraphs (g), (h), (i) and (j) have been removed. The assumption in paragraph (e) has been revised so that it does not apply to the guarantor.

3. Please have counsel remove the language in paragraph (b) on page four noting that it relied “exclusively” upon the certificates listed.

Response: The language in paragraph (b) on page four relating to counsel’s relying “exclusively” upon the certificates listed has been removed.

Exhibits 5.6 and 5.7

4. We note the assumption in Schedule B of each opinion that the bylaws or operating agreements, as applicable, and all amendments thereto, have been adopted in accordance with all legal requirements. It appears that this assumption may be resolved by diligence of counsel. Please advise or revise as appropriate.

Response: The assumption in Schedule B of each opinion relating to the bylaws or operating agreements, as applicable, has been removed.

Please direct any questions or comments regarding the foregoing to the undersigned at (213) 891-7421. Thank you in advance for your cooperation in connection with this matter.

Very truly yours,
