-24-

agreed that the Lessees shall have no obligation to give notices to any such participant, that such participation will not in any way reduce the Series 2006-1 Letter of Credit Provider’s commitment to make LOC Disbursements hereunder, and that such participation (other than a participation held by a Revolving Lender pursuant to the Credit Agreement) shall not increase the obligations (including with respect to costs and expenses) of the Lessees hereunder); provided that the Series 2006-1 Letter of Credit Provider shall be entitled to receive any increased costs or indemnities payable hereunder incurred by the Series 2006-1 Letter of Credit Provider or such participant to the extent not in excess of such amounts calculated as if there were no participation.

The obligations of the Lessees under Sections 2.5, 4.1, 4.2 and 4.3 shall in each case survive any termination of this Agreement, the payment in full of all obligations hereunder or under any other Related Document and the termination of the Series 2006-1 Letter of Credit.

Section 4.13 Obligation. Each of the Series 2006-1 Letter of Credit Provider and each of the Lessees understands and agrees that the Series 2006-1 Letter of Credit is irrevocable and the obligations of the Series 2006-1 Letter of Credit Provider as issuer thereof shall be unaffected by any default hereunder, including, without limitation any failure to pay the amounts due and payable to the Series 2006-1 Letter of Credit Provider under Section 2.4. No failure of any of the Lessees (or any person or organization acting on behalf thereof) or the Trustee to take any action (whether required hereunder or otherwise), nor any action taken by any of the Lessees shall be asserted by the Series 2006-1 Letter of Credit Provider as a defense to

-25-

payment under the Series 2006-1 Letter of Credit (except for the failure of any documents presented thereunder to comply with the terms of the Series 2006-1 Letter of Credit) or as the basis of a right of set off by the Series 2006-1 Letter of Credit Provider against its obligations to make any such payment.

Section 4.14 Headings. Section headings in this Agreement are included herein for convenience of reference only and shall not constitute a part of this Agreement for any other purpose.

Section 4.15 Confidentiality. The Series 2006-1 Letter of Credit Provider agrees that it shall not disclose any Confidential Information (as defined below) to any Person without the consent of DTAG, the Lessees or RCFC, as applicable, other than (a) to the Series 2006-1 Letter of Credit Provider’s Affiliates and to the Administrative Agent, the Revolving Lenders and the Term Lenders and their respective officers, directors, employees, agents and advisors and to actual or prospective assignees and participants, and then only on a confidential basis, (b) as required by any law, rule or regulation or judicial process, (c) as requested or required by any state, federal or foreign authority or examiner regulating banks or banking or (d) as otherwise permitted by Section 11.14 of the Credit Agreement (which is incorporated herein by reference).

“Confidential Information” means information that DTAG, the Lessees or RCFC furnishes to the Series 2006-1 Letter of Credit Provider on a confidential basis, but does not include any such information that is or becomes generally available to the public or that is or becomes available to the Series 2006-1 Letter of Credit Provider from a source other than DTAG, the Lessees or RCFC.

Section 4.17 Additional Subsidiary Lessees. Any direct or indirect Subsidiary of DTAG (each a “DTAG Subsidiary”) shall have the right to become a “Lessee” under and pursuant to the terms of this Agreement by complying with the provisions of Section 28.1 of the Master Lease and the provisions of this Section 4.17. In the event a DTAG Subsidiary desires to become “Lessee” under this Agreement, then the Guarantor and such DTAG Subsidiary shall execute and deliver to the Series 2006-1 Letter of Credit Provider and the Trustee:

(i) an Affiliate Joinder in Enhancement Letter of Credit Application and Agreement in the form attached hereto as Exhibit B (each, an “Affiliate Joinder in Enhancement Letter of Credit Application and Agreement”);

-26-

(iii) an Officers’ Certificate and an opinion of counsel each stating that the joinder described in clause (i) above by such DTAG Subsidiary complies with this Section 4.17 and that all conditions precedent herein provided for relating to such transaction have been complied with; and

(iv) any additional documentation that the Series 2006-1 Letter of Credit Provider or the Trustee may reasonably require to evidence the assumption by such DTAG Subsidiary of the obligations and liabilities set forth in this Agreement.

Upon satisfaction of the foregoing conditions and receipt by each of the Trustee and the Series 2006-1 Letter of Credit Provider of original executed copies of the applicable Affiliate Joinder in Enhancement Letter of Credit Application and Agreement executed by such DTAG Subsidiary and the Guarantor, such DTAG Subsidiary shall for all purposes be deemed to be a “Lessee” for purposes of this Agreement and shall be entitled to the benefits and subject to the liabilities and obligations of a Lessee hereunder.

Section 4.18 Enhancement Letter of Credit Application and Agreement. This Agreement is an Enhancement Letter of Credit Application and Agreement executed pursuant to the Credit Agreement. In the event that, after construing the terms of this Agreement and the Credit Agreement in a manner that would seek to avoid any purported inconsistency or conflict between the terms of this Agreement, on the one hand, and the terms of the Credit Agreement, on the other hand, such inconsistency or conflict cannot be avoided, the terms of this Agreement shall control.

Section 4.19 Series 2006-1 Letter of Credit Provider as Enhancement Provider and Third-Party Beneficiary. The Lessees, RCFC and DTAG each hereby acknowledges and agrees that the Series 2006-1 Letter of Credit Provider is (i) an “Enhancement Provider” (as such term is used in the Base Indenture) and (ii) without limiting the effect of any other provision contained in the Base Indenture or the Series 2006-1 Supplement, a third-party beneficiary of the provisions set forth in Article 11 of the Base Indenture, Section 8.7 of the Series 2006-1 Supplement and Section 22 of the Master Lease.

Section 4.20 No Recourse; No Petition. (a) Each of the parties hereto hereby covenants and agrees that:

(i) no recourse shall be had for the payment of any amount owing in respect of any disbursement made under this Agreement or the Series 2006-1 Letter of Credit or for the payment of any fee hereunder or thereunder or any other obligation or claim arising out of or based upon this Agreement or the Series 2006-1 Letter of Credit against RCFC or any stockholder, employee, officer, director or incorporator of RCFC based on their status as such or their actions in connection therewith; and

(ii) prior to the date which is one year and one day after the payment in full of any Notes issued by RCFC pursuant to the Indenture, such party will not institute against, or join with any other Person in instituting against, RCFC, any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings, or other proceedings under any Federal or state bankruptcy or similar law, all as more particularly set forth in

-27-

Section 12.15 of the Base Indenture and subject to any retained rights set forth therein (it being agreed and understood that nothing contained herein shall preclude participation by any such party in assertion or defense of its claims in any such proceeding involving RCFC);

provided, however, that nothing in this clause (a) shall constitute a waiver of any right to indemnification, reimbursement or other payment from RCFC to such party pursuant to any Related Document (other than this Agreement) to which RCFC is a party.

(b) In the event that any such party takes action in violation of clause (a)(ii), RCFC agrees that it shall file an answer with the bankruptcy court or otherwise properly contest the filing of such a petition by such party against RCFC or the commencement of such action and raise the defense that such Person has agreed in writing not to take such action and should be estopped and precluded therefrom and such other defenses, if any, as its counsel advises that it may assert.
