(a) if amounts are required to be withdrawn from the Debt Service Reserve Account pursuant to Section 10.01(b), and the amounts to be so withdrawn exceed the funds, not including the aggregate Stated Amounts of the Debt Service Reserve Letters of Credit standing to the credit of the Debt Service Reserve Account, in the amount necessary to make the payments of Debt Service then due and payable;

(b) in full, if the commercial bank that issued such Debt Service Reserve Letter of Credit is no longer an Acceptable Bank; or

If, on any Quarterly Payment Date, the funds on deposit in or standing to the credit of the Debt Service Reserve Account (taking into account the Stated Amounts of any Debt Service Reserve Letters of Credit standing to the credit of the Debt Service Reserve Account) are in excess of the Debt Service Reserve Required Amount, unless a Notice of Suspension is

in effect or a Default or Event of Default would occur as a result of such transfer, the Borrower may direct, by delivery of a Debt Service Reserve Release Certificate to the Accounts Bank (with a copy to the Administrative Agent), the transfer to the Revenue Account of an amount equal to the difference between (x) the aggregate total amount of all funds on deposit in or standing to the credit of the Debt Service Reserve Account (taking into account the Stated Amounts of any Debt Service Reserve Letters of Credit standing to the credit of the Debt Service Reserve Account) and (y) the Debt Service Reserve Required Amount, as certified by the Borrower and confirmed by the Administrative Agent in such Debt Service Reserve Release Certificate; provided, that if such difference is positive due to the posting of a Debt Service Reserve Letter of Credit to the Debt Service Reserve Account to replace or substitute for cash then on deposit, such amount may be distributed directly to any Pledgor or such other Affiliate of the Borrower who provided such Debt Service Reserve Letter of Credit (and such distribution shall not be treated as a Restricted Payment for purposes of this Accounts Agreement).

INTEREST AND INVESTMENTS

Section 16.01 Investments. (a) Each amount deposited in or credited to a Project Account from time to time shall, from the time it is so deposited or credited until the time it is withdrawn from that Project Account (whether for the purpose of making an investment in Cash Equivalents or otherwise applied in accordance with the terms of this Accounts Agreement), earn interest at such rates as may be agreed from time to time by the Borrower and the Accounts Bank.

(b) Prior to the receipt by the Accounts Bank of a Notice of Suspension, any amounts held by the Accounts Bank in the Project Accounts shall be invested by the Accounts Bank from time to time, at the risk and expense of the Borrower, solely in such Cash Equivalents as an Authorized Officer of the Borrower shall direct in writing (which may be in the form of a standing instruction). The Borrower shall select Cash Equivalents having such maturities as shall cause the Project Accounts to have a cash balance as of any day sufficient to cover the transfers to be made from the Project Accounts on such day in accordance with this Accounts Agreement, the Credit Agreement, the other Financing Documents, the Project Documents and any Additional Project Documents. Upon delivery by the Collateral Agent to the Accounts Bank of a Notice of Suspension and until written revocation of such Notice of Suspension is delivered to the Accounts Bank by the Collateral Agent, any amounts held by the Accounts Bank in the Project Accounts shall be invested by the Accounts Bank from time to time, solely in such Cash Equivalents as the Collateral Agent or the Administrative Agent, in its sole discretion, may direct; provided that the Accounts Bank’s obligation to invest such amounts is conditioned upon receipt by the Accounts Bank of a valid United States Department of the Treasury Internal Revenue

Service tax Form W-9 in accordance with Section 16.03(b) (Interest and Investment Income). Neither the Collateral Agent, the Accounts Bank nor the Administrative Agent shall be liable for any loss resulting from any Cash Equivalents (or any investment or reinvestment therein or liquidation or redemption thereof) from any Project Account or the sale or redemption thereof except to the extent that such loss results solely from the gross negligence or willful misconduct of the Collateral Agent, the Accounts Bank or the Administrative Agent, as the case may be, it being understood and agreed that in no event shall any of the Administrative Agent, the Accounts Bank or the Collateral Agent, as the case may be, be liable for any loss resulting from any investment made, or any sale or redemption of any investment made, in accordance with instructions received from the Borrower, the Collateral Agent or the Administrative Agent, as the case may be, or failure to receive written direction as required hereunder, or in accordance with Section 16.02 (Sale and Liquidation) hereof.

Section 16.02 Sale and Liquidation. In the event that the cash balance in any of the Project Accounts is as of any day insufficient to cover the transfers to be made from such Project Account on such day (and if advised in writing by the Administrative Agent or the Borrower of such circumstances), the Collateral Agent may (but shall not be obligated to) direct the Accounts Bank, without instructions from the Borrower, to sell or liquidate the Cash Equivalents standing to the credit of such Project Account (without regard to maturity date) in such manner as the Collateral Agent may direct in order to obtain cash at least sufficient to make such transfers and to pay any expenses and charges incurred in connection with effecting any such sale or liquidation, which expenses and charges the Accounts Bank shall be authorized to pay with cash on deposit in such Project Account. Neither the Accounts Bank, the Collateral Agent nor any other Senior Secured Party shall be liable to any Person for any loss suffered because of any such sale or liquidation.

Section 16.03 Interest and Investment Income. (a) All interest and other investment income earned from investments in Cash Equivalents made from amounts in any Project Account shall remain in such Project Account until transferred from such Project Account in accordance with the terms of this Accounts Agreement.

The Borrower shall be responsible for determining any requirements for paying Taxes or reporting or withholding any payments for Tax purposes hereunder. The Borrower shall prepare and file all Tax information required with respect to the Project Accounts. The Borrower agrees to indemnify and hold each Senior Secured Party and each Second Lien Claimholder harmless against all liability for Tax withholding and/or reporting for any investment income earned on the Project Accounts and payments in respect thereof. Such

indemnities shall survive the termination or discharge of this Accounts Agreement or resignation of the Accounts Bank. None of the Collateral Agent, the Accounts Bank, the Second Lien Agent, any Senior Secured Party or any Second Lien Claimholder shall have any obligation with respect to the making of or the reporting of any payments for Tax purposes. From time to time, and as reasonably requested by the Accounts Bank, the Borrower shall provide to the Accounts Bank a United States Department of the Treasury Internal Revenue Service tax Form W-9 or other appropriate form required with respect to the withholding or exemption from withholding of income tax on any investment income earned on the Project Accounts. The Accounts Bank shall be entitled to rely on an opinion of legal counsel (which may be counsel to the Borrower) in connection with the reporting of any earnings with respect hereto.

Section 16.04 Accounts Information. (a) The Accounts Bank will:

(i) within ten (10) Business Days after the end of the month in which the first deposit is made into any Project Account and within ten (10) Business Days after the end of each month thereafter, provide the Borrower, the Collateral Agent and the Administrative Agent a report with respect to the Project Accounts, setting forth in reasonable detail all deposits to and disbursements from each of the Project Accounts during such month, including the date on which made, and the balances of and any investments in each of the Project Accounts at the end of such month, including information regarding categories, amounts, maturities and issuers of Cash Equivalents; and

(ii) within ten (10) Business Days after receipt of any written request by the Borrower, the Collateral Agent, the Administrative Agent or the Second Lien Agent, provide to the Borrower, the Collateral Agent, the Administrative Agent or the Second Lien Agent, as the case may be, such other information as the Borrower, the Collateral Agent, the Administrative Agent, or the Second Lien Agent, as the case may be, may reasonably specify regarding all Cash Equivalents and any other investments made by the Accounts Bank pursuant hereto and regarding amounts available in the Project Accounts.

(b) The Accounts Bank will maintain all of the Project Accounts and all books and records with respect thereto as may be necessary to record properly all transactions carried out by it under this Accounts Agreement.

(c) If any Cash Equivalent ceases to be a Cash Equivalent, the Accounts Bank will, as soon as reasonably practicable after becoming aware of such cessation, notify the Collateral Agent and the Borrower in writing of such cessation and, upon the written direction of the Borrower (or, if the Borrower fails to provide direction within three (3) Business Days of the date of the Accounts Bank’s notice, upon the written direction of the Collateral Agent), will cause the relevant investment to be replaced by a Cash Equivalent or by cash; provided that this Section 16.04(c) will not oblige the Accounts Bank to liquidate any investment earlier than its normal maturity date unless:

(i) directed to do so under Section 16.02 (Sale and Liquidation); or

(ii) the maturity date of the relevant investment exceeds the maturity date that would enable it to continue to qualify as a Cash Equivalent.

ARTICLE XVII

(c) The Accounts Bank shall promptly comply with any instruction given by the Collateral Agent as contemplated by Section 2.01 (Appointment) (without reference to any inconsistent request or instruction from the Borrower or otherwise).

ARTICLE XVIII

THE ACCOUNTS BANK

Section 18.01 Duties of the Accounts Bank and Securities Intermediary. (a) The Accounts Bank, acting as Securities Intermediary, will have the obligations of a securities intermediary under Article 8 of the UCC, and acting as a bank with respect to the Project Accounts, will have the obligations of a bank under Article 9 of the UCC. The Accounts Bank will also have those duties and responsibilities expressly set forth in this Accounts Agreement, and no additional duties, responsibilities, obligations or liabilities shall be inferred from the provisions of this Accounts Agreement or imposed on the Accounts Bank. The Accounts Bank will act at the written direction of the Collateral Agent, the Administrative Agent and, as expressly provided in this Accounts Agreement, the Borrower, but will not be required to take any action that is contrary to this Accounts Agreement or applicable Law or that, in its reasonable judgment, would involve it in expense or liability, unless it has been furnished with adequate indemnity and/or security against such expense or liability. The Accounts Bank will have no responsibility to ensure the performance by any other party of its duties and obligations hereunder. The Accounts Bank will use the same care with respect to the safekeeping and handling of property held in the Project Accounts as the Accounts Bank uses in respect of property held for its own sole benefit. The provisions of this Article XVIII are solely for the benefit of the Accounts Bank, the Collateral Agent and the Senior Secured Parties.

(b) In performing its functions and duties under this Accounts Agreement, the Accounts Bank will act solely as the depository of the Collateral Agent, for the benefit of the Senior Secured Parties, and as Securities Intermediary or as a bank, as the case may be, with respect to the Project Accounts for the benefit of the Collateral Agent, for the benefit of the Senior Secured Parties. The Accounts Bank does not assume and will not be deemed to have assumed any obligation toward or relationship of agency or trust with or for the Borrower or any Person other than the Collateral Agent. None of the Senior Secured Parties, the Second Lien Agent, any Second Lien Claimholder or the Borrower will have any rights against the Accounts Bank hereunder, other than for the Accounts Bank’s gross negligence or willful misconduct. Except as otherwise expressly provided in this Accounts Agreement, the Borrower will not have any right to direct the Accounts Bank to distribute or allocate any funds, instruments, securities, financial assets or other assets in the Project Accounts or to withdraw or transfer any funds, instruments, securities, financial assets or other assets from the Project Accounts. Except as otherwise expressly provided in this Accounts Agreement,

the Collateral Agent, on behalf of the Senior Secured Parties, will have the sole right to issue directions and instructions to the Accounts Bank, acting as Securities Intermediary or bank, as the case may be, in accordance with this Accounts Agreement, and to issue entitlement orders with respect to the Project Accounts. It is expressly understood and agreed that any investment made with funds held in the Project Accounts may be made only in accordance with the express provisions of Section 16.01 (Investments) and, when an investment is so made, it is expressly understood and agreed that such investment was made with the permission of the Collateral Agent in the exercise of its exclusive possession of, and dominion and control over, the Project Accounts, which it maintains through the Accounts Bank. The Accounts Bank shall not in any way whatsoever be liable for any loss or depreciation in the value of any investments made pursuant to the terms of this Accounts Agreement.

Section 18.02 Exculpatory Provisions. (a) Neither the Accounts Bank nor any of its directors, officers, employees or agents will have any duties or obligations except those expressly set forth herein or required by applicable law.

(iii) except as expressly set forth herein, have any duty to disclose, nor shall the Accounts Bank be liable for any

failure to disclose, any information relating to the Borrower or any of its Affiliates that is communicated to or obtained by the Accounts Bank or any of its Affiliates in any capacity; or

(d) The Accounts Bank may, unless and until it shall have received directions from the Required Lenders or the Administrative Agent, take such action or refrain from taking such action in respect of a Default or Event of Default of which the Accounts Bank has been advised in writing by the Required Lenders or the Administrative Agent as it shall reasonably deem advisable in the best interests of the Lenders (but shall not be obligated to do so).

Section 18.03 Reliance by Accounts Bank. The Accounts Bank shall be entitled to rely upon, and shall not (nor shall any of its directors, officers, employees or agents) incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing (including any electronic message, internet or intranet website posting or other distribution) believed by it to be genuine and to have been signed, sent or otherwise authenticated by the proper Person. The Accounts Bank also may rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper Person, and shall not incur any liability for relying thereon. The Accounts Bank may consult with legal counsel (who may be counsel for the Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts. The Accounts Bank may at any time and from time to time solicit written instructions in the form of directions from the Administrative Agent, the Collateral Agent or the Required Lenders or an order of a court of competent jurisdiction, as to any action that it may be requested or required to take, or that it may propose to take, in the performance of any of its obligations under this Accounts Agreement.

Section 18.04 Written Instructions; Notices. (a) Notwithstanding anything in this Accounts Agreement, the Credit Agreement, any other Financing Document or any Subordinated Debt Document to the contrary, the Accounts Bank shall have no obligation to (i) make any payment, transfer or withdrawal from any Project Account until it has received written direction to make such payment, transfer or withdrawal from the Administrative Agent, the Collateral Agent or the Borrower as set forth herein or (ii) determine whether any payment, transfer or withdrawal from any Project Account made in accordance with any written direction from the Administrative Agent, the Collateral Agent or the Borrower complies with the terms of this Accounts Agreement. The Accounts Bank shall have no liability for, nor any responsibility or obligation to confirm, the use or application by the Borrower, the Collateral Agent or the Administrative Agent or any other recipient of amounts withdrawn or transferred from any Project Account.

(b) Except as otherwise provided in this Accounts Agreement, the Accounts Bank shall take action under this Accounts Agreement only as it shall be directed in writing by the Collateral Agent or the Administrative Agent. In each case that the Accounts Bank may or is required under the other Financing Documents to take any action (an “Accounts Bank Action”), including without limitation to make any determination or judgment, to give consents, to exercise rights, powers or remedies or otherwise to act hereunder, under any other Financing Document, the Accounts Bank may seek direction from the Collateral Agent or the Administrative Agent and shall be entitled to refrain from such Accounts Bank Action unless and until it has received such direction and shall not incur any liability to any Person by reason of so refraining.

Section 18.05 Resignation or Removal of Accounts Bank. (a) The Accounts Bank may resign from the performance of all its functions and duties hereunder at any time by giving thirty (30) days’ prior notice to the Borrower and the Collateral Agent. The Accounts Bank may be removed (i) at any time by the Administrative Agent or the Required Lenders, or (ii) in the event of a material breach by the Accounts Bank of its duties hereunder, by the Borrower in consultation with the Administrative Agent. Such resignation or removal shall take effect upon the appointment of a successor Accounts Bank, in accordance with this Section 18.05.

(b) Upon the notice of resignation by the Accounts Bank or upon the removal of the Accounts Bank pursuant to Section 18.05(a), the Administrative Agent shall appoint a successor Accounts Bank hereunder, who shall be a commercial bank having a combined capital and surplus of at least two hundred fifty million Dollars ($250,000,000).

Such court may thereupon, after such notice, if any, as it may deem proper, appoint a successor Accounts Bank who shall serve as Accounts Bank hereunder until such time, if any, as the Administrative Agent appoints a successor Accounts Bank, as provided above.

(d) Upon the acceptance of a successor’s appointment as Accounts Bank hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring (or removed) Accounts Bank, and the retiring (or removed) Accounts Bank shall be discharged from all of its duties and obligations hereunder. After the retirement or removal of the Accounts Bank hereunder, the provisions of this Article XVIII shall continue in effect for the benefit of the retiring (or removed) Accounts Bank in respect of any actions taken or omitted to be taken by it while the retiring or removed Accounts Bank was acting as Accounts Bank.

transactions contemplated hereunder, in all cases, whether or not caused by or arising, in whole or in part, out of the comparative, contributory or sole negligence of the Indemnitee.

provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses are determined by a court of competent jurisdiction by final and non-appealable judgment to have resulted from the gross negligence or willful misconduct of such Indemnitee.

(b) The Borrower hereby agrees, subject to the terms of the Intercreditor Agreement, to indemnify the Second Lien Agent and each Related Party thereof (each such Person being called an “Second Lien Agent Indemnitee”) against, and hold each Second Lien Agent Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses (including all reasonable fees, costs and expenses of counsel for any Second Lien Agent Indemnitee), incurred by any Second Lien Agent Indemnitee or asserted against any Second Lien Agent Indemnitee by any third party or by the Borrower arising out of, in connection with, or as a result of:

(ii) any funds deposited in or credited to any Project Account or the use or proposed use of the proceeds therefrom; and

(iii) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory, whether brought by a third party, the GP Pledgor or any of its shareholders, directors or creditors, the Borrower or any of its partners or creditors, and in each case regardless of whether any Second Lien Agent Indemnitee is a party thereto and whether or not any of the transactions contemplated hereunder, in all cases, whether or not caused by or arising, in whole or in part, out of the comparative, contributory or sole negligence of the Second Lien Agent Indemnitee;

provided that such indemnity shall not, as to any Second Lien Agent Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses are determined by a court of competent jurisdiction by final and non-appealable judgment to have resulted from the gross negligence or willful misconduct of such Second Lien Agent Indemnitee.
