Each Borrowing shall be in the amount of U.S. Dollars specified by the Issuing Bank, from time to time, as the amount required to reimburse the Issuing Bank for any amount drawn under the Letter of Credit but not reimbursed by the Borrowers when due pursuant to Section 2.12(c). Each Borrowing shall consist of Letter of Credit Advances made on the same day by the Lenders ratably according to their respective Commitments.

(b) Unless the Administrative Agent shall have received notice from a Lender prior to the date of any Borrowing that such Lender will not make available to the Administrative Agent such Lender’s ratable portion of such Borrowing, the Administrative Agent may assume that such Lender has made such portion available to the Administrative Agent on the date of such Borrowing in accordance with subsection (a) of this Section 2.02 and the Administrative Agent may, in reliance upon such assumption, make available to the Borrowers on such date a corresponding amount.

Letter of Credit is outstanding, provided that in the event that PDGL has cash collateralized in accordance with the provisions of Section 2.13 all or a portion of the Letter of Credit in an amount in excess of the Minimum Required Balance (the “Relevant Amount”) and no Default or Event of Default shall have occurred and be continuing, the Letter of Credit Fee respecting such Relevant Amount shall be twenty-five (25) basis points (0.25%) for the period of such cash collateralization, and (B) an annual margin fee (the “Margin Fee”) of one percent (1%) of the “Deficit” (defined below); the “Deficit” shall be the amount by which the total Commitments exceed the USD equivalent of the face amount of the TI Bond. For purposes of calculating the Letter of Credit Fee and the Margin Fee under this Section 2.03(a), the Naira equivalent of Dollars and the Dollar equivalent of Naira on any day shall be determined by the Issuing Bank on the basis of the average of the rates of exchange on each “Valuation Date” (as herein defined) during the relevant period used by the Issuing Bank in good faith in accordance with normal banking procedures. For the purpose of this Section 2.03(a), the term “Valuation Date” means the last Business Day of each calendar week commencing with the last Business Day of April 20, 2012; provided that if a Default or Event of Default shall have occurred and be continuing, the Valuation Date may be such Business Day as the Issuing Bank, in its sole discretion, shall designate upon notice to the Borrowers and the Lenders. (ii) The Borrowers, jointly and severally, shall pay to the Issuing Bank an annual fronting fee of ten (10) basis points (0.10%) of the total Commitments, payable to the Issuing Bank, at the time of the initial issuance, and at each annual renewal or extension, of the Letter of Credit, together with such other commissions, transfer fees and other fees and charges in connection with the issuance or administration of the Letter of Credit as the Borrowers and such Issuing Bank shall agree.

(c) Defaulting Lender’s Fees. Anything herein to the contrary notwithstanding, during such period as a Lender is a Defaulting Lender, such Defaulting Lender will not be entitled to any fees accruing during such period pursuant to Section 2.03(a) (without prejudice to the rights of the Non-Defaulting Lenders in respect of such fees).

Section 2.04 Repayment of Letter of Credit Advances The Borrowers shall repay to the Administrative Agent for the ratable account of the Lender Parties, the aggregate principal amount of each Letter of Credit Advance outstanding no later than the day when such Advance is drawn or, if notice is given to the Borrowers of the drawing of such Advance later than 10:00 AM (New York time) on the day when drawn, then on the next Business Day, provided that all such amounts shall be paid on the Termination Date. No principal amount of an Advance paid may be reborrowed.

Section 2.05 Interest. (a) Scheduled Interest. The Borrowers shall pay interest on the unpaid principal amount of each Advance owing to each Lender Party from the date such Advance is made until such principal amount shall be paid in full at a rate per annum equal at all times to the sum of (x) the Base Rate in effect from time to time plus (y) the Applicable Margin in effect from time to time, payable in arrears within three (3) Business Days following notice thereof from the Administrative to the Borrowers and on the date such Base Rate Advance shall be paid in full.

(b) Default Interest. Upon the occurrence and during the continuance of an Event of Default, the Borrowers shall pay interest on (i) the unpaid principal amount of each Advance owing to each Lender Party, payable in arrears on the dates referred to in clause (a) above, at a rate per annum equal at all times to 2% per annum above the rate per annum required to be paid on such Advance pursuant to clause (a) above (“Default Interest”), as the case may be, and (ii) to the fullest extent permitted by law, the amount of any interest, fee or other amount payable hereunder that is not paid when due, from the date such amount shall be due until such amount shall be paid in full, payable in arrears on the date such amount shall be paid in full and within three (3) Business Days following notice thereof from the Administrative Agent to the Borrowers, at a rate per annum equal at all times to 2% per annum above the rate per annum required to be paid on Base Rate Advances pursuant to clause (a) above.

Section 2.06 Application of Payments Received. Payments made pursuant to this Agreement by the Borrowers, and all cash Collateral and proceeds of Collateral, shall be first applied to reimburse the Issuing Bank for all amounts drawn under the Letter of Credit but not reimbursed and all other amounts due the Issuing Bank under the Loan Documents until all such amounts are paid in full, and second applied to pay Letter of Credit Advances then outstanding comprising part of the same Borrowing until all such Advances are paid in full, in each case, together with the respective interest accrued thereon, and third applied to payment of all other amounts due the Administrative Agent and the Lenders until all such amounts are paid in full.

If any Lender Party determines (taking into account such Lender’s Party’s, or its controlling corporation’s, policies with respect to capital adequacy) that compliance, which compliance was not required as of the date hereof, with any law or regulation or any guideline or request from any central bank or other Governmental Authority (whether or not having the force of law) affects or would affect the amount of capital required or expected to be maintained by such Lender or any corporation controlling such Lender Party and that the amount of such capital is increased by or based upon the existence of such Lender’s Party commitment to lend hereunder and other commitments of such type or the issuance or maintenance of Letters of Credit (or similar contingent obligations), then, within thirty (30) days after notice thereof from the Administrative to the Borrowers by such Lender Party (with a copy of such notice to the Administrative Agent), the Borrowers shall pay to the Administrative Agent for the account of such Lender Party, from time to time as specified by such Lender Party, additional amounts sufficient to compensate such Lender or such corporation in the light of such circumstances, to the extent that such Lender reasonably determines such increase in capital to be allocable to the existence of such Lender’s Party’s commitment to lend hereunder or to the issuance or maintenance of the Letter of Credit. A certificate as to such amounts submitted to the Borrowers and the Administrative Agent by such Lender shall be conclusive and binding for all purposes, absent manifest error.

(a) The Borrowers shall make each payment hereunder and under the Advances not later than 1:00 P.M. (New York City time) on the day when due in Dollars to the Administrative Agent at the Administrative Agent’s Account in immediately available funds.

The Administrative Agent will promptly thereafter cause to be distributed like funds relating to the payment of principal or interest or fees ratably (other than amounts payable pursuant to Section 2.07 or Section 2.09) to the Lenders for the account of their respective Applicable Lending Offices, and like funds relating to the payment of any other amount payable to any Lender to such Lender for the account of its Applicable Lending Office, in each case to be applied in accordance with the terms of this Agreement. Upon its acceptance of an Assignment and Acceptance and recording of the information contained therein in the Register pursuant to Section 9.07(c), from and after the effective date specified in such Assignment and Acceptance, the Administrative Agent shall make all payments hereunder and under the Advances in respect of the interest assigned thereby to the Lender assignee thereunder, and the parties to such Assignment and Acceptance shall make all appropriate adjustments in such payments for periods prior to such effective date directly between themselves.

(b) In the event that the debt obligations of PDL and PBL under the PFA and the other debt obligations of the other obligors therein named have been paid or prepaid in full and all the commitments of the lenders under the PFA have been terminated, the Borrowers hereby authorize each Lender, if and to the extent payment owed to such Lender is not made when due hereunder, to charge from time to time against any or all of such Borrowers’ accounts with such Lender any amount so due. Each Lender agrees promptly to notify the Borrowers after any such charge against any Borrower’s accounts, provided that the failure to give such notice shall not affect the validity of such charge.

(c) All computations of interest based on the rate of interest set forth in clause (a) of the definition of “Base Rate” shall be made by the Administrative Agent on the basis of a year of 365 or 366 days, as the case may be, and all computations of interest based on the Federal Funds Rate or on the rate of interest set forth in clause (b) of the definition of “Base Rate” and of fees and Letter of Credit Fees shall be made by the Administrative Agent on the basis of a year of 360 days, in each case for the actual number of days elapsed (including the first day but excluding the last day) occurring in the period for which such interest or fees are payable. Each determination by the Administrative Agent of an interest rate or fee shall be conclusive and binding for all purposes, absent manifest error. Each determination of the Issuing Bank of the Reimbursement Obligation hereunder shall be conclusive and binding for all purposes, absent manifest error.

(d) Whenever any payment hereunder or under the Advances shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of interest or fee, as the case may be.

(e) Unless the Administrative Agent shall have received notice from the Borrowers prior to the date on which any payment is due to any Lender hereunder that the Borrowers will not make such payment in full, the Administrative Agent may assume that the Borrowers have made such payment in full to the Administrative Agent on such date and the Administrative Agent may, in reliance upon such assumption, cause to be distributed to each such Lender on such due date an amount equal to the amount then due such Lender. If and to the extent the Borrowers shall not have so made such payment in full to the Administrative Agent, each such Lender shall repay to the Administrative Agent forthwith on demand such amount distributed to such Lender together with interest thereon, for each day from the date such amount is distributed to such Lender until the date such Lender repays such amount to the Administrative Agent, at the Federal Funds Rate.

(a) All amounts payable by any Obligor under the Loan Documents (or by any other Person on account of any obligation of any Obligor under the Loan Documents) shall be paid free and clear of and without deduction or withholding for or on account of any Taxes, wire transfer fees or other charges or withholdings of any nature, except to the extent that the deduction or withholding of any Tax is required by applicable law, in which event such Obligor shall (i) give the Administrative Agent prompt written notice of such requirement, (ii) except to the extent (if any) that such Tax is an Excluded Tax, pay to the Person entitled to receive such payment (the “Payee”) such additional amount as is necessary so that the Payee receives, after such deduction or withholding (including any withholding with respect to such additional amount), an amount equal to the amount that the Payee would have received if such deduction or withholding had not been made, (iii) make the deduction or withholding required by applicable law and pay the amount deducted or withheld to the relevant Taxing Authority in accordance with applicable law, and (iv) deliver to the Administrative Agent as soon as practicable after the date of such payment the original (or a certified copy of) a receipt issued by such Taxing Authority evidencing its receipt of such payment or, if such Taxing Authority does not issue receipts for such Tax payments, other documentary evidence of such payment reasonably satisfactory to the Administrative Agent.

(b) The Obligors, jointly and severally, shall pay to the appropriate Taxing Authority when due (and shall defend, indemnify and hold harmless the Arranger and each Secured Party and each of their respective Affiliates, directors, officers, employees, agents and authorized representatives (each a “Tax Indemnitee”), upon demand, from and against) all Taxes arising from or otherwise relating to (i) the Loan Documents or the Collateral, or (ii) the execution, delivery, issuance, acquisition, holding, ownership, transfer, assumption, filing, registration, recording, performance, enforcement, amendment, supplement or other modification of any of the Loan Documents, or (iii) any payment by any Obligor or any other Person on account of any obligation of any Obligor under the Loan Documents, or otherwise arising from or relating to the transactions contemplated in the Loan Documents (including any penalties, interest, charges, costs and expenses relating thereto), whether or not such Taxes were correctly or legally imposed or asserted by the relevant Taxing Authority, provided that no Obligor shall have any obligation under this Section 2.09(b) to indemnify any Secured Party for the following Taxes (“Excluded Taxes”): (x) any Tax on or measured by the net income of such Secured Party (or any franchise Tax imposed on such Secured Party in lieu of a net income Tax) imposed by any Taxing Authority in the jurisdiction in which the principal place of business or Applicable Lending Office of such Secured Party is located or (y) any Tax imposed on such Secured Party as a result of a present or former connection between such Secured Party and the jurisdiction imposing such Tax (other than a connection arising from the transactions contemplated in the Loan Documents, including such Secured Party having executed, delivered, become a party to, performed its obligations under, received payments under, received or perfected a security interest under, or enforced its rights under this Agreement or any other Loan Document), or (z) any Tax imposed as a result of a failure of such Secured Party to comply with its obligations under Section 2.09(g).

(c) Each additional amount payable pursuant to Section 2.09(a) and each indemnity payable pursuant to Section 2.09(b) shall be paid on an “after-tax basis” which means that the amount payable shall be increased by an amount (the “gross-up amount”) equal to the sum of all Taxes payable by any Payee or Tax Indemnitee with respect to the receipt or accrual of such payment (including the gross-up amount).

(d) The indemnities contained in this Section 2.09 shall continue in full force and effect notwithstanding the expiration, cancellation or termination of this Agreement and the other Loan Documents, and are expressly made for the benefit of and shall be enforceable by each Tax Indemnitee.

(e) In addition, the Borrower shall pay any present or future stamp, documentary, excise, property or similar taxes, charges or levies that arise from any payment made hereunder or under the Advances or from the execution, delivery or registration of, performance under, or otherwise with respect to, this Agreement or the Advances (hereinafter referred to as “Other Taxes”).

(f) The Borrower shall indemnify each Lender Party and the Administrative Agent for and hold them harmless against the full amount of Taxes (other than Excluded Taxes) and Other Taxes imposed by any jurisdiction on amounts payable under this Section 2.09, imposed on or paid by such Lender Party or the Administrative Agent (as the case may be) and any liability (including penalties, additions to tax, interest and expenses) arising therefrom or with respect thereto. This indemnification shall be made within thirty (30) days from the date such Lender Party or the Administrative Agent (as the case may be) makes written demand therefor. Within thirty (30) days after the date of any payment by the Borrower of Taxes pursuant to this Section 2.09, the Borrower shall furnish to the Administrative Agent, at its address referred to in Section 9.02, the original or a certified copy of a receipt evidencing such payment or other documentary evidence of payment reasonably satisfactory to the Administrative Agent.

(g) Any Secured Party that is entitled, under the law of the jurisdiction in which the Borrower is resident or under any treaty to which such jurisdiction is a party, to exemption from (or reduction of) a withholding Tax with respect to payments made under any Loan Document shall, as soon as reasonably practicable after receipt of the Borrower’s written request therefor (accompanied by a copy of each requested form, any published instructions for such form, and an English translation of each such form and instruction that is not in English), deliver to the Borrower and the Administrative Agent such completed and executed forms or other documents as (i) the Borrower may reasonably request and (ii) such Secured Party is legally entitled to provide and (iii) the Borrower is required by law to obtain to permit such payments to be made without withholding (or subject to withholding at a reduced rate, as the case may be) any withholding Tax that would be required by law to be withheld from such payments in the absence of such document, provided that in the case of any such document that must be provided, executed or endorsed by any Governmental Authority or other Taxing Authority, the failure of such Secured Party or the Borrower to receive such document from such

Governmental Authority or other Taxing Authority within a reasonable time shall not be deemed to be a failure to comply with this Section 2.09(g) so long as such Secured Party is using commercially reasonable efforts to obtain such document, and provided, further, that no Secured Party shall have any obligation to deliver any document pursuant to this Section 2.09 if such Secured Party determines that delivering such document is reasonably likely to result in such Secured Party incurring or suffering a non-de-minimis liability, loss, cost, expense or other adverse consequence.

(h) Any Lender Party claiming any indemnity or additional amounts payable pursuant to this Section 2.09 agrees to use reasonable efforts (consistent with its internal policy and legal and regulatory restrictions) to change the jurisdiction of its Applicable Lending Office if the making of such a change would avoid the need for, or reduce the amount of, any such indemnity or additional amounts that may thereafter accrue and would not, in the reasonable judgment of such Lender Party, be otherwise disadvantageous to such Lender Party.

Section 2.10 Sharing of Payments, Etc. If any Lender shall obtain any payment (whether voluntary, involuntary, through the exercise of any right of set-off, or otherwise) on account of the Advances owing to it (other than pursuant to Section 2.07, 2.09 or Section 9.04(c) or pursuant to that certain Deposit Account Control Agreement dated as of April 19, 2012 between PDGL, as grantor and DVB Bank SE, Nordic Branch, as Secured Party in respect of the Deposit Account (described thereunder)) in excess of its ratable share of payments on account of the Advances obtained by all the Lenders, such Lender shall forthwith purchase from the other Lenders such participations in the Advances owing to them as shall be necessary to cause such purchasing Lender to share the excess payment ratably with each of them; provided, however, that if all or any portion of such excess payment is thereafter recovered from such purchasing Lender, such purchase from each Lender shall be rescinded and such Lender shall repay to the purchasing Lender the purchase price to the extent of such recovery together with an amount equal to such Lender’s ratable share (according to the proportion of (i) the amount of such Lender’s required repayment to (ii) the total amount so recovered from the purchasing Lender) of any interest or other amount paid or payable by the purchasing Lender in respect of the total amount so recovered. The Borrowers agree that any Lender so purchasing a participation from another Lender pursuant to this Section 2.10 may, to the fullest extent permitted by law, exercise all its rights of payment (including the right of set off) with respect to such participation as fully as if such Lender were the direct creditor of the Borrower in the amount of such participation.

Section 2.11 Use of Proceeds The proceeds of the Advances shall be used to pay the Reimbursement Obligations to the Issuing Bank.

Section 2.12 Issuance of and Drawings and Reimbursement Under Letters of Credit.

(a) Letter of Credit. The Issuing Bank agrees, on the terms and conditions hereinafter set forth, to issue on the Initial Extension of Credit Date a standby letter of credit (the “Letter of Credit”) for the account of the Borrowers in favor of the TI Bond Issuing Bank, in substantially the form attached hereto as Exhibit K, in an aggregate face amount not to exceed the Issuing Bank’s Letter of Credit Commitment. The Letter of Credit shall expire at or prior to the close of business in New York on the first anniversary of the date of issuance thereof, provided that the Letter of Credit may, upon request of the Borrowers include a provision

whereby such Letter of Credit may be renewed for additional consecutive periods of 12 months or less, subject to the provisions of Section 2.12(i), provided that the consent of the Issuing Bank will be required for any such renewal, as set forth in Section 2.12(i), and provided further however that the initial issuance of the Letter of Credit shall be not later than April 30, 2012. The Letter of Credit shall be denominated in Naira, provided that the Borrowers’ Reimbursement Obligation in respect thereof shall be in U.S. Dollars. For the avoidance of doubt, each drawing under the Letter of Credit shall permanently reduce the Letter of Credit Commitment in the amount of such drawing regardless whether or not the Issuing Bank is reimbursed such amount drawn.

(b) Request for Issuance. The Letter of Credit shall be issued upon notice, given not later than 1:00 P.M. (New York City time) on the fifth Business Day prior to the date of the proposed issuance of such Letter of Credit, by the Borrowers to the Issuing Bank, which shall give to the Administrative Agent and each Lender prompt notice thereof by telecopier. The notice of issuance of the Letter of Credit (a “Notice of Issuance”) shall be by telephone, confirmed immediately in writing, or telecopier, in substantially the form of Exhibit A hereto, specifying therein the requested (A) date of such issuance (which shall be a Business Day), (B) Available Amount of the Letter of Credit, (C) expiration date of the Letter of Credit, (D) name and address of the beneficiary of the Letter of Credit and (E) form of such Letter of Credit, and shall be accompanied by such application and agreement for letter of credit as the Issuing Bank may specify to the Borrowers for use in connection with the requested Letter of Credit (the “Letter of Credit Agreement”). The Notice of Issuance shall be irrevocable and binding on the Borrowers. The Issuing Bank will, upon fulfillment of the applicable conditions set forth in Article III make such Letter of Credit available to the Borrowers at its office referred to in Section 9.02 or as otherwise agreed with the Borrowers in connection with such issuance. In the event and to the extent that the provisions of the Letter of Credit Agreement shall conflict with this Agreement, the provisions of this Agreement shall govern. Upon the issuance of the Letter of Credit, each Lender shall be deemed to have acquired a risk participation in such Letter of Credit to the extent of its Pro Rata Share of the Available Amount of the Letter of Credit.

(c) Drawing and Reimbursement. The payment by the Issuing Bank of a draft drawn under the Letter of Credit shall constitute for all purposes of this Agreement the making by the Issuing Bank of a Letter of Credit Advance, which shall be a Base Rate Advance, in the amount of the Reimbursement Obligation relating to such draft as of the date of such Letter of Credit Advance as specified by the Issuing Bank from time to time. Upon written demand by the Issuing Bank, with a copy of such demand to the Administrative Agent, each Lender shall make, to the extent of its Commitment, an Advance in an amount equal to such Lender’s Pro Rata Share of the Issuing Bank’s outstanding Letter of Credit Advance as of such date in order to refinance the Issuing Bank’s Letter of Credit Advance, by making available for the account of its Applicable Lending Office to the Administrative Agent for the account of the Issuing Bank, by deposit to the Administrative Agent’s Account, in immediately available funds, an amount equal to the portion of the outstanding principal amount of such Letter of Credit Advance to be made by such Lender; provided, that, at any time prior to the date on which such written demand is made, the Borrowers shall be permitted to repay the full amount of such payment on same-day notice to the Administrative Agent and the Issuing Bank. Promptly after receipt of such payment, the Administrative Agent shall transfer such funds to the Issuing Bank. The Borrowers hereby agree to each Letter of Credit Advance. Each Lender agrees to make its Letter of Credit

Advance on (i) the Business Day on which demand therefor is made by the Issuing Bank, provided notice of such demand is given not later than 10:00 A.M. (New York City time) on such Business Day or (ii) the first Business Day next succeeding such demand if notice of such demand is given after such time. Upon any such refinancing by any Lender of a portion of the Letter of Credit Advance made by the Issuing Bank, the Issuing Bank represents and warrants to such Lender that the Issuing Bank is the legal and beneficial owner of such interest being assigned by it, free and clear of any liens, but makes no other representation or warranty and assumes no responsibility with respect to such Letter of Credit Advance, the Loan Document or any Obligor. If and to the extent that any Lender shall not have so made the amount of such Letter of Credit Advance available to the Administrative Agent, such Lender agrees to pay to the Administrative Agent forthwith on demand such amount together with interest thereon, for each day from the date of demand by the Issuing Bank until the date such amount is paid to the Administrative Agent, at the Federal Funds Rate for its account or the account of the Issuing Bank, as applicable. If such Lender shall pay to the Administrative Agent such amount for the account of the Issuing Bank on any Business Day, such amount so paid in respect of principal shall constitute a Letter of Credit Advance made by such Lender on such Business Day for purposes of this Agreement, and the outstanding principal amount of the Letter of Credit Advance made by the Issuing Bank shall be reduced by such amount on such Business Day.

(d) Failure to Make Letter of Credit Advances. The failure of any Lender to make the Letter of Credit Advance to be made by it on the date specified in Section 2.12(c) shall not relieve any other Lender of its obligation hereunder to make its Letter of Credit Advance on such date, but no Lender shall be responsible for the failure of any other Lender to make the Letter of Credit Advance to be made by such other Lender on such date.

(e) Letter of Credit Advances. (i) Upon a Lender making available to the Administrative Agent the amount of the Letter of Credit Advance refinanced pursuant to Section 2.12(c), such amount of such Letter of Credit Advance shall be deemed to be payable to such Lender. The amount of any Advance in excess of the total Commitments of the Lenders shall be payable to the Issuing Bank. The Borrowers, jointly and severally, shall repay to the Administrative Agent for the account of the Issuing Bank and each Lender that has a Letter of Credit Advance on the earliest of (y) the date such Letter of Credit Advance is required to be paid pursuant to Section 2.04 and (z) the Termination Date, the outstanding principal amount of each Letter of Credit Advance made by each of them.

(ii) The obligations of the Borrowers under this Agreement with respect to the Letter of Credit, any Letter of Credit Agreement and any other agreement or instrument relating to the Letter of Credit, including without limitation, the obligation to repay any Advance arising from a drawing on the Letter of Credit, shall be unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement, such Letter of Credit Agreement and such other agreement or instrument under all circumstances, including, without limitation, the following circumstances and regardless of the use of proceeds of any drawing under the Letter of Credit or any defense related thereto:

(A) any lack of validity or enforceability of this Agreement, any Letter of Credit Agreement, the Letter of Credit, any other Loan Document or any other agreement or instrument relating thereto (all of the foregoing being, collectively, the “L/C Related Documents”);

(B) any change in the time, manner or place of payment of, or in any other term of, all or any of the obligations of the Borrowers in respect of any L/C Related Document or any other amendment or waiver of or any consent to departure from all or any of the L/C Related Documents;

(C) the existence of any claim, set off, defense or other right that any Borrower or any other Person may have at any time against any beneficiary or any transferee of the Letter of Credit (or any Persons for whom any such beneficiary or any such transferee may be acting), the Issuing Bank or any other Person, whether in connection with the transactions contemplated by the L/C Related Documents or any unrelated transaction;

(D) any statement or any other document presented under the Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect;

(E) payment by the Issuing Bank under the Letter of Credit against presentation of a draft or certificate that does not strictly comply with the terms of such Letter of Credit;

(F) any exchange, release or non perfection of any collateral, or any release or amendment or waiver of or consent to departure from any guaranty, for all or any of the obligations of the Borrower in respect of the L/C Related Documents; or

(G) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing, including, without limitation, any other circumstance that might otherwise constitute a defense available to, or a discharge of, the Borrowers’ obligations hereunder or any other guarantor.

(f) Limited Liability of the Issuing Bank. The Obligors assume all risks of the acts or omissions of any beneficiary or transferee of the Letter of Credit with respect to its use of the Letter of Credit. Neither the Issuing Bank nor any of its officers or directors shall be liable or responsible for: (a) the use that may be made of the Letter of Credit or any acts or omissions of any beneficiary or transferee in connection therewith; (b) the validity, sufficiency or genuineness of documents, or of any endorsement thereon, even if such documents should prove to be in any or all respects invalid, insufficient, fraudulent or forged; (c) payment by the Issuing Bank against presentation of documents that do not comply with the terms of the Letter of Credit, including failure of any documents to bear any reference or adequate reference to the Letter of Credit; or (d) any other circumstances whatsoever in making or failing to make payment under the Letter of Credit, except that the Borrowers shall have a claim against the Issuing Bank, and the Issuing Bank shall be liable to the Borrowers, to the extent of any direct, but not consequential, damages suffered by the Borrowers that the Borrowers prove were caused by (i) the Issuing Bank’s willful misconduct or gross negligence in determining whether documents presented under the Letter of Credit comply with the terms of the Letter of Credit or (ii) the Issuing Bank’s willful failure to make lawful payment under the Letter of Credit after the

presentation to it of a draft and certificates strictly complying with the terms and conditions of the Letter of Credit. In furtherance and not in limitation of the foregoing, the Issuing Bank may accept documents that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary.

(g) Disbursement Procedures. The Issuing Bank shall, promptly following its receipt thereof, examine all documents purporting to represent a demand for payment under the Letter of Credit. The Issuing Bank shall promptly notify the Administrative Agent and the Borrowers by telephone (confirmed by telecopy) of such demand for payment and whether the Issuing Bank has made or will make an LC Disbursement thereunder; provided that any failure to give or delay in giving such notice shall not relieve the Borrowers of their obligations to reimburse the Issuing Bank and the Lenders with respect to any such LC Disbursement.

(i) (A) L/C Cash Collateral Account. If any Event of Default shall occur and be continuing on the Business Day that the Borrowers receive notice from the Issuing Bank, the Administrative Agent or the Required Lenders demanding the deposit of cash collateral pursuant to this Section 2.12(h), the Borrowers hereby agree to deposit an amount equal to the aggregate amount available at such time to be drawn under the Letter of Credit (such aggregate amount as determined from time to time being the “Required Balance”) in a cash collateral account to be established by PDGL and maintained by the Administrative Agent pursuant to a Cash Collateral Agreement over which the Administrative Agent shall have sole dominion and control (the “L/C Cash Collateral Account”) in Naira or U.S. Dollars, or both, as the Issuing Bank may require or as the Borrowers may elect subject to the consent of the Issuing Bank, upon terms substantially set forth in such Cash Collateral Agreement. Without limitation of the foregoing provisions of this Section 2.12(h)(i), above (but without duplication), the Borrowers shall maintain at all times in the L/C Cash Collateral Account, in Naira or U.S. Dollars, or both, an amount not less than 10.5% of the Required Balance (such amount, the “Minimum Required Balance”) provided, however, that in no event shall the Minimum Required Balance ever be less than 10.5% of the aggregate Commitments of the Lenders set forth in Schedule I hereto. The Administrative Agent shall, at the Borrowers’ direction and without assuming any risk of loss thereof, invest the funds in the L/C Cash Collateral Account in Cash Equivalents for the account of the Borrowers. All interest and other investment gains earned on such investments shall be added to the L/C Cash Collateral Account as additional collateral security for the prompt and complete payment when due of the obligations and liabilities of the Borrowers and under and in respect of the Letter of Credit. On (i) the last Business Day of each calendar week, the Administrative Agent or (ii) any other date that the Borrowers, the Administrative Agent or Required Lenders through the Administrative Agent or the Issuing Bank shall in writing request, the Administrative Agent shall determine whether the amount on deposit on such date in the L/C Cash Collateral Account (A) is greater than the Minimum Required Balance or the Required Balance, as the case may be, on such date (the amount of such excess being the “Excess Amount”) or (B) is less than the Minimum Required Balance or the Required Balance, as the case may be, on such date (the amount of such deficit being the “Deficit Amount”). The Administrative Agent shall advise the Borrowers on the date of determination of the existence, if any, of any Excess Amount or Deficit Amount and thereafter (i) the Borrowers shall immediately upon receipt of notice from the Administrative Agent of the existence of any

Deficit Amount, pay to the Administrative Agent for deposit in the L/C Cash Collateral Account or the FX Cash Collateral Account, as the Administrative Agent shall determine, as additional funds to be deposited and held in such cash collateral account, an amount equal to such Deficit Amount or (ii) upon request of the Borrowers within five (5) Business Days of receipt of notice from the Administrative Agent of the existence of any Excess Amount, the Administrative Agent shall release to the Borrowers from the funds on deposit in the L/C Cash Collateral Account an amount equal to such Excess Amount provided no Default or Event of Default has occurred and is continuing. If at any time the Administrative Agent determines that any funds held in the L/C Cash Collateral Account are subject to any right or claim of any Person other than the Administrative Agent, the Issuing Bank or the Lenders, which right or claim could reasonably have the effect of reducing the value of such funds to the Lenders and the Issuing Banks, the Borrowers will, forthwith upon receipt of a demand by the Administrative Agent, pay to the Administrative Agent, as additional funds to be deposited and held in such L/C Cash Collateral Account, an amount equal to the amount by which the value of such funds to the Lenders and the Issuing Bank has been reduced as determined by the Administrative Agent.

(B) FX Cash Collateral Account. PDGL hereby agrees to establish, on or before the second Business Day before the Initial Extension of Credit Date, a foreign exchange cash collateral account in the name of PDGL and maintained by the Administrative Agent pursuant to the FX Cash Collateral Agreement over which the Administrative Agent shall have sole dominion and control (the “FX Cash Collateral Account”) in U.S. Dollars, upon terms substantially set forth in such FX Cash Collateral Agreement.

(ii) PDGL hereby grants to the Administrative Agent a security interest in any amounts from time to time on deposit in each of the L/C Cash Collateral Account and the FX Cash Collateral Account as collateral security for the prompt and complete payment when due of the obligations and liabilities of the Borrowers under and in respect of the Letter of Credit.

(iii) The Borrowers, the Administrative Agent, the Issuing Bank and the Lenders agree that any action taken or omitted to be taken by the Administrative Agent in connection with the L/C Cash Collateral Account and/or the FX Cash Collateral Account, if taken or omitted to be taken in good faith and with reasonable care, shall be binding upon the Borrowers, the Issuing Banks and the Lenders and shall not create any liability on the part of the Administrative Agent to the Borrowers, the Issuing Bank or the Lenders.

(i) Renewal of Letter of Credit. The Letter of Credit may automatically extend or renew for one or more, but not more than two (2), additional successive one-year periods beyond its stated expiry date as herein provided in this Section 2.12(i).

In the event that, at least forty (40), but not more than forty-five (45), days before such then-current expiry date, the Issuing Bank and the Administrative Agent have received from the Owner an irrevocable written notice (a “Notice of Extension”) requesting a one-year extension of the Letter of Credit, the Letter of Credit shall automatically extend for such additional one-year period, unless the Issuing Bank sends written notice to the Owner at least twenty (20), but not more than thirty (30), days before the then-current expiry date of its decision not to so extend the Letter of Credit.

In any event, if an event of default has occurred and is continuing under the PFA, the Issuing Bank shall not extend the Letter of Credit beyond its then-current term if it has received at least twenty-five (25), but not more than thirty (30), days before the then-current expiry date of the Letter of Credit, a request from Lenders holding at least two-thirds (2/3) of the outstanding Commitments and Advances.

Each Notice of Extension shall be accompanied by a certificate signed by the Obligors to the effect that:

(1) All representations and warranties of the Obligors are true and correct on and as of the date of the Notice of Extension, before and after giving effect to such Notice of Extension and the extension or renewal of the Letter of Credit as therein requested.

(2) No Default or Event of Default has occurred and is continuing, or would result from the extension or renewal of the Letter of Credit as therein requested.

(3) The Vessel has not suffered a Total Loss or Major Casualty Event (as defined in the PFA).

Section 2.13 Cash Security Pricing PDGL may, at the time of issuance or any renewal of the Letter of Credit, deposit in a cash collateral account of PDGL held by the Administrative Agent for the sole benefit of the Issuing Bank all or any portion of the face amount of the Letter of Credit in an amount equal to 105% of the portion so collateralized. Any such cash collateral shall be held in the collateral account for the entire then-existing one-year term of the Letter of Credit and will be subject to application as collateral for the Reimbursement Obligations owed and that may be owed to the Issuing Bank. Such cash collateral shall be in the amount of U.S. Dollars specified by the Issuing Bank as equivalent to the Naira amount to be secured; the U.S. Account Parties agree to make additional U.S. Dollar cash collateral deposits on request of the Issuing Bank to account for fluctuations in the U.S. Dollar/Naira exchange rate advised from time to time by the Issuing Bank (and, provided no Default or Event of Default has occurred and is continuing, the Issuing Bank shall likewise return any excess amounts to account for fluctuations such exchange rate from time to time upon request of PDGL). The cash security arrangement will have such features as the Issuing Bank advises may be required to satisfy Office of Currency Control and Federal Reserve guidance for capital adequacy in cash secured engagements. Upon written request of PDGL to the Administrative Agent and the Issuing Bank given at least thirty (30) days prior to the then-scheduled expiry date of the Letter of Credit, the Administrative Agent shall return all amounts remaining in such cash collateral account to PDGL following expiry of the Letter of Credit and its return to the Issuing Bank, provided no Default or Event of Default has occurred and is then continuing.

Section 2.14 Special Cash Collateralization In the event that for any reason the debt obligations of PDL and PBL under the PFA and the other debt obligations of the other obligors therein named have been paid or prepaid in full and all the commitments of the lenders under the PFA have been terminated, then the U.S. Account Parties shall deposit in an account of PDGL with the Administrative Agent as security for their Obligations under this Agreement and the other Loan Documents, and PIDWAL’s obligations under the TI Bond, an amount in U.S. dollars equal to 105% of the amount, specified by the Issuing Bank, that would have been required to be

paid as reimbursement under the Letter of Credit had a drawing of the full amount of the TI Bond then been made, to be held as such security for so long as the TI Bond shall be outstanding. Such cash collateral shall be in the amount of U.S. Dollars specified by the Issuing Bank as equivalent to the Naira amount to be secured; the U.S. Account parties agree to make additional U.S. Dollar cash collateral deposits on request of the Issuing Bank to account for fluctuations in the U.S. Dollar/Naira exchange rate advised from time to time by the Issuing Bank (and, provided no Default or Event of Default has occurred and is continuing, the Issuing Bank shall likewise return any excess amounts to account for fluctuations such exchange rate from time to time upon request of PDGL). The cash security arrangement will have such features as the Issuing Bank advises may be required to satisfy Office of Currency Control and Federal Reserve guidance for capital adequacy in cash secured engagements. Upon written request of PDGL to the Administrative Agent and the Issuing Bank given at least thirty (30) days prior to the then-scheduled expiry date of the Letter of Credit, the Administrative Agent shall return all amounts remaining in such cash collateral account to PDGL following expiry of the Letter of Credit and its return to the Issuing Bank, provided no Default or Event of Default has occurred and is then continuing.

Section 2.15 Replacement of Lenders If any Lender (i) requests reimbursement for amounts owing or the payment of additional amounts pursuant to Section 2.07 or Section 2.09, or (ii) does not consent to any proposed amendment, supplement, modification, consent or waiver of any provision of this Agreement or any other Loan Document that requires the consent of each of the Lenders or each of the Lenders affected thereby (so long as the consent of the Required Lenders (with the percentage in such definition being deemed to be 80% for this purpose) has been obtained), then the Borrowers may, at their sole expense and effort, upon notice to such Lender and the Administrative Agent and with the consent of the Issuing Bank, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in Section 9.07), all its interests, rights and obligations under this Agreement to an assignee that shall assume such obligations (which assignee must be an Eligible Assignee); such Lender shall have received payment of an amount equal to the outstanding principal of its Advances and participations in LC Disbursements, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrowers (in the case of all other amounts) and in the case of any such assignment resulting from a claim for compensation under Section 2.07 or payments required to be made pursuant to Section 2.09, such assignment will result in a reduction in such compensation or payments. A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrowers to require such assignment and delegation cease to apply.

(i) The Owner hereby agrees to establish in its name, on or prior to the date hereof, a deposit account designated the “Owner’s Drilling Contract Reimbursement Proceeds Account” and maintained by the Administrative Agent pursuant to the Owner’s Drilling Contract Reimbursement Proceeds Account Collateral Agreement over which the Administrative

Agent shall have sole dominion and control (the “Owner’s Drilling Contract Reimbursement Proceeds Account”) in U.S. Dollars, upon terms substantially set forth in such Owner’s Drilling Contract Reimbursement Proceeds Account Collateral Agreement. In accordance with the provisions of Clause 26.5(b)(i) of the PFA, the Owner shall promptly transfer from the Collection Account and deposit into the Owner’s Drilling Contract Reimbursement Proceeds Account, any and all Drilling Contract Reimbursement Proceeds at any time standing to the credit of the Collection Account.

(ii) The Owner hereby grants to the Administrative Agent a security interest in any amounts from time to time on deposit in the Owner’s Drilling Contract Reimbursement Proceeds Account and all Drilling Contract Reimbursement Proceeds, as collateral security for the prompt and complete payment when due of the obligations and liabilities of the Borrowers under and in respect of the Letter of Credit.

(i) The Owner hereby agrees to establish in its name, on or prior to the date hereof, a deposit account designated the “Owner’s Insurance Proceeds Account” and maintained by the Administrative Agent pursuant to the Owner’s Insurance Proceeds Account Collateral Agreement over which the Administrative Agent shall have sole dominion and control (the “Owner’s Insurance Proceeds Account”), upon terms substantially set forth in such Owner’s Insurance Proceeds Account Collateral Agreement. In accordance with the provisions of Clause 26.5(b)(vii) of the PFA, the Owner shall promptly transfer from the Collection Account and deposit into the Owner’s Insurance Proceeds Account, any and all Insurance Proceeds at any time standing to the credit of the Collection Account.

(ii) The Owner hereby grants a security interest in any amounts from time to time on deposit in the Owner’s Insurance Proceeds Account, as collateral security for the prompt and complete payment when due of the obligations and liabilities of the Borrowers under and in respect of the Letter of Credit.

(c) Order of Application of Certain Funds. Any amounts in the Owner’s Drilling Contract Reimbursement Proceeds Account and the Owner’s Insurance Proceeds Account used to satisfy any reimbursement and repayment obligations of the Borrowers under this Agreement to the Lender Parties, shall be applied by the Lender Parties as follows: first by applying proceeds of the Owner’s Drilling Contract Reimbursement Proceeds Account and, second, by applying proceeds of the Owner’s Insurance Proceeds Account. If any amount remains in the Owner’s Insurance Proceeds Account or the Owner’s Drilling Contract Reimbursement Proceeds Account following the full and final discharge of all liabilities owed to the Lender Parties pursuant to this Agreement, the provisions of, as applicable, Clause 26.19 or Clause 26.20 of the PFA shall apply.

(d) Owner Reimbursement Liabilities. The Owner shall indemnify PDL, PDSA, PIDWAL, PDGL or any Additional TI Bond Facility Obligors (as defined in the ICA) for any amount paid out by PDL, PDSA, PIDWAL, PDGL or, as the case may be, any Additional TI

(i) the Owner’s aggregate liability under this Section 2.16(d) and any analogous obligations arising by operation of law shall not exceed the aggregate amounts that the Borrower is permitted to incur pursuant to the Intercreditor Agreement;

(ii) any amount payable under this Section 2.16(d) or in respect of any analogous obligations arising by operation of law shall only be payable by the Owner from sums that are available to it under the terms of the PFA to pay as Borrower Reimbursement Distributions (as defined in the PFA) at the time that such payment is due pursuant to paragraph (iii) below;

(iii) the Owner’s liability to indemnify PDL, PDSA, PIDWAL, PDGL or, as the case may be, any Additional TI Bond Facility Obligors (as defined in the ICA) under this Section 2.16(d) shall arise when such person makes a payment under or in connection with this Agreement, but shall only become due and payable when the Borrower is permitted to pay a Borrower Reimbursement Distribution (under, and as defined in, the PFA);

(iv) if the Owner is liable to indemnify two or more of PDL, PDSA, PIDWAL, PDGL or any Additional TI Bond Facility Obligor under this Section 2.16(d) at any time, the Owner shall, in its sole discretion, decide the priority in which it makes payment to such persons; and

(v) any amount that has become due and payable under this Section 2.16(d), but is not paid by reason of the operation of this Section 2.16(d) shall be deemed no longer to be due and payable (without prejudice to the Owner’s on-going liability to indemnify and such liability again becoming due and payable pursuant to paragraph (iii) above).

(a) Reallocation of Defaulting Lender Commitment. If a Lender becomes, and during the period it remains, a Defaulting Lender, the following provisions shall apply with respect to any undrawn Commitment of such Defaulting Lender:

(i) any amount paid by the Borrowers or otherwise received by the Administrative Agent for the account of a Defaulting Lender under this Agreement (whether on account of principal, interest, fees, indemnity payments or other amounts) will not be paid or distributed to such Defaulting Lender, but will instead be retained by the Administrative Agent in a segregated non-interest bearing account until the termination of the Commitments and payment in full of all obligations of the Borrowers hereunder and will be applied by the Administrative Agent, to the fullest extent permitted by law, to the making of payments from time to time in the following order of priority: first to the payment of any amounts owing by such Defaulting Lender to the Issuing Bank under this Agreement, second to the payment of any amounts owing by such Defaulting Lender to the Administrative Agent under this Agreement, third to the payment of post-default interest and then current interest due and payable to the

Lenders hereunder other than Defaulting Lenders, ratably among them in accordance with the amounts of such interest then due and payable to them, fourth to the payment of fees then due and payable to the Non-Defaulting Lenders hereunder, ratably among them in accordance with the amounts of such fees then due and payable to them, fifth to pay principal and unreimbursed LC Disbursements then due and payable to the Non-Defaulting Lenders hereunder ratably in accordance with the amounts thereof then due and payable to them, sixth to the ratable payment of other amounts then due and payable to the Non-Defaulting Lenders, and seventh after the termination of the Commitments and payment in full of all obligations of the Borrowers hereunder, to pay amounts owing under this Agreement to such Defaulting Lender or as a court of competent jurisdiction may otherwise direct;

(b) Termination of Defaulting Lender Commitment. The Borrowers may terminate the unused amount of the Commitment of a Defaulting Lender upon not less than ten (10) Business Days’ prior notice to the Administrative Agent (which will promptly notify the Lenders thereof), and in such event the provisions of Section 2.06 will apply to all amounts thereafter paid by the Borrowers for the account of such Defaulting Lender under this Agreement (whether on account of principal, interest, fees, indemnity or other amounts), provided that such termination will not be deemed to be a waiver or release of any claim the Borrowers, the Administrative Agent, the Issuing Bank or any Lender may have against such Defaulting Lender.

Section 6.02 Actions in Respect of the Letter of Credit upon Default With respect to the Letter of Credit with respect to which presentment for honor shall not have occurred at the time of an acceleration pursuant to the preceding paragraph, the Borrowers shall at such time deposit in a non-interest bearing cash collateral account opened by, and under the sole dominion and control of, the Administrative Agent an amount equal to the aggregate Available Amount of the Letter of Credit then outstanding, and the Borrowers hereby grant to the Administrative Agent for the benefit of the Administrative Agent, the Issuing Bank and the Lenders a security interest in all funds so deposited to and from time to time held (in the form of cash, certificates or instruments) in the cash collateral account and proceeds thereof. The Borrowers and the Administrative Agent shall thereafter enter into documentation reaffirming the grant of the security interest hereunder and otherwise relating to such cash collateral account in form and substance satisfactory to the Administrative Agent and the Borrowers. The Administrative Agent shall, at the Borrowers’ direction and without assuming any risk of loss thereof, invest the funds in the cash collateral account in Cash Equivalents for the account of the Borrowers. All interest and other investment gains earned on such investments shall be added to the cash collateral account as additional collateral security for the prompt and complete payment when due of the obligations and liabilities of the Borrowers under and in respect of the Letter of Credit.

Amounts held in such cash collateral account shall be applied by the Administrative Agent to the payment of drafts drawn under the Letter of Credit, and the unused portion thereof after the Letter of Credit shall has expired or been fully drawn upon, if any, shall be applied to repay other obligations of the Borrowers hereunder and under the Advances. If at any time the Administrative Agent determines that any funds held in such cash collateral account are subject to any right or claim of any Person other than the Administrative Agent, the Issuing Bank or the Lenders, which right or claim could reasonably have the effect of reducing the value of such funds to the Issuing Bank and the Lenders, or that the total amount of such funds is less than the aggregate Available Amount of all Letters of Credit, the Borrowers will, forthwith upon receipt of a demand by the Administrative Agent, pay to the Administrative Agent, as additional funds in Dollars to be deposited and held in such cash collateral account, an amount equal to (a) the amount by which the value of such funds to the Lenders and the Issuing Bank has been reduced, or (b) the excess of (i) such aggregate Available Amount over (ii) the total amount of funds, if any, then held in such cash collateral account, respectively. On or after the date the Letter of Credit shall have expired or been fully drawn upon, all Reimbursement Obligations shall have been satisfied and all other obligations of the Borrowers hereunder and under the Advances then due and payable shall have been paid in full and the TI Bond shall have expired or been cancelled, the balance, if any, in such cash collateral account shall be returned to the Borrowers.

Without limiting the generality of the foregoing, the Guarantor’s liability shall extend to all amounts that constitute part of the PDSA Guaranteed Obligations and would be owed by each Document Party to the Administrative Agent, the Issuing Bank or any Lender under the L/C Related Documents but for the fact that they are unenforceable or not allowable due to the existence of a bankruptcy, reorganization or similar proceeding involving such Document Party.

Section 7.02 Guaranty Absolute The Guarantor guarantees that the PDSA Guaranteed Obligations will be paid strictly in accordance with the terms of the L/C Related Documents, regardless of any law, regulation or order now or hereafter in effect in any jurisdiction affecting any of such terms or the rights of the Administrative Agent, the Issuing Bank or any Lender with respect thereto. The obligations of the Guarantor under the guaranty contained in this Article VII are independent of the PDSA Guaranteed Obligations or any other Obligations of any other Document Party under the L/C Related Documents, and a separate action or actions may be brought and prosecuted against the Guarantor to enforce the guaranty contained in this Article VII, irrespective of whether any action is brought against any Document Party or whether any Document Party is joined in any such action or actions. The liability of the Guarantor under the guaranty contained in this Article VII shall be irrevocable, absolute and unconditional irrespective of, and the Guarantor hereby irrevocably waives, any defenses it may now or hereafter have in any way relating to, any or all of the following:

(g) any other circumstance (including, without limitation, any statute of limitations) or any existence of or reliance on any representation by the Administrative Agent, the Issuing Bank or Lender that might otherwise constitute a defense available to, or a discharge of, any Document Party, the Guarantor or any other guarantor or surety (other than the defense of payment or performance).

The guaranty contained in this Article VII shall continue to be effective or be reinstated, as the case may be, if at any time any payment of any of the PDSA Guaranteed Obligations is rescinded or must otherwise be returned by the Administrative Agent, the Issuing Bank or Lender or any other Person upon the insolvency, bankruptcy or reorganization of any Document Party or otherwise, all as though such payment had not been made.

The provisions of this Article are solely for the benefit of the Administrative Agent, the Lenders and the Issuing Bank, and none of the Borrowers nor any other Obligor shall have rights as a third-party beneficiary of any of such provisions. As to any matters not expressly provided for by the Loan Documents (including, without limitation, enforcement or collection of the Advances), the Administrative Agent shall not be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of the Required Lenders, and such instructions shall be binding upon all Lender Parties and all holders of Advances; provided, however, that the Administrative Agent will not be required to take any action that, in its opinion or the opinion of its counsel, may expose the Administrative Agent to liability or that is contrary to any Loan Document or applicable law, including for the avoidance of doubt, any action that

The Administrative Agent agrees to give to each Lender Party prompt notice of each notice given to it by the Obligors pursuant to the terms of this Agreement.

Section 8.02 Administrative Agent’s Reliance, Etc. Neither the Administrative Agent nor any of its respective directors, officers, agents or employees shall be liable for any action taken or omitted to be taken by it or them under or in connection with the Loan Documents, except for its or their own gross negligence or willful misconduct. Without limitation of the generality of the foregoing, the Administrative Agent: (a) may treat the payee of any Advance as the holder thereof until the Administrative Agent receives and accepts an Assignment and Acceptance entered into by the Lender that is the payee of such Advance, as assignor, and an Eligible Assignee, as assignee, as provided in Section 9.07; (b) may consult with legal counsel (including counsel for any Document Party), independent public accountants and other experts selected by it and shall not be liable for any action taken or omitted to be taken in good faith by it in accordance with the advice of such counsel, accountants or experts; (c) makes no warranty or representation to any Lender Party and shall not be responsible to any Lender Party for any statements, warranties or representations (whether written or oral) made in or in connection with the Loan Documents; (d) shall not have any duty to ascertain or to inquire as to the performance, observance or satisfaction of any of the terms, covenants or conditions of any Loan Document on the part of any Document Party or the existence at any time of any Default under the Loan Documents or to inspect the property (including the books and records) of any Document Party; (e) shall not be responsible to any Lender Party for the due execution, legality, validity, enforceability, genuineness, sufficiency or value of, or the perfection or priority of any lien or security interest created or purported to be created under or in connection with, any Loan Document or any other instrument or document furnished pursuant thereto; and (f) shall incur no liability under or in respect of any Loan Document by acting upon any notice, consent, certificate or other instrument or writing (which may be by telegram, telecopy or telex) believed by it to be genuine and signed or sent by the proper party or parties.

Section 8.03 Citibank and Affiliates With respect to its Commitments, the Advances made by it, Citibank shall have the same rights and powers under the Loan Documents as any other Lender Party and may exercise the same as though it were not the Administrative Agent; and the term “Lender Party” or “Lender Parties” shall, unless otherwise expressly indicated, include Citibank in its individual capacity. Citibank and its Affiliates may accept deposits from, lend money to, act as trustee under indentures of, accept investment banking engagements from and generally engage in any kind of business with, any Document Party, any of its Subsidiaries and any Person that may do business with or own securities of any Document Party or any such Subsidiary, all as if Citibank was not an Agent and without any duty to account therefor to the Lender Parties. The Administrative Agent shall not have any duty to disclose any information obtained or received by it or any of its Affiliates relating to any Document Party or any of its Subsidiaries to the extent such information was obtained or received in any capacity other than as the Administrative Agent.

Section 8.04 Party Credit Decision Each Lender Party acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender Party and based on the financial statements referred to in Section 4.01 and such other documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender Party also acknowledges that it will, independently and without reliance upon the Administrative Agent or any other Lender Party and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement.

(a) Each Lender Party severally agrees to indemnify the Administrative Agent (to the extent not promptly reimbursed by the Obligors) from and against such Lender Party’s ratable share (determined as provided below) of any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever that may be imposed on, incurred by, or asserted against the Administrative Agent in any way relating to or arising out of the Loan Documents or any action taken or omitted by the Administrative Agent under the Loan Documents (collectively, the “Indemnified Costs”); provided, however, that no Lender Party shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from the Administrative Agent’s gross negligence or willful misconduct as found in a final, non-appealable judgment by a court of competent jurisdiction. Without limitation of the foregoing, each Lender Party agrees to reimburse the Administrative Agent promptly upon demand for its ratable share of any costs and expenses (including, without limitation, fees and expenses of counsel) payable by the Obligors under Section 9.04, to the extent that the Administrative Agent is not promptly reimbursed for such costs and expenses by the Obligors. In the case of any investigation, litigation or proceeding giving rise to any Indemnified Costs, this Section 8.05 applies whether any such investigation, litigation or proceeding is brought by any Lender Party or any other Person.

(b) Each Lender Party severally agrees to indemnify the Issuing Bank (to the extent not promptly reimbursed by the Borrowers) from and against such Lender Party’s ratable share (determined as provided below) of any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever that may be imposed on, incurred by, or asserted against the Issuing Bank in any way relating to or arising out of the Loan Documents or any action taken or omitted by the Issuing Bank under the Loan Documents; provided, however, that no Lender Party shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from the Issuing Bank’s gross negligence or willful misconduct as found in a final, non-appealable judgment by a court of competent jurisdiction. Without limitation of the foregoing, each Lender Party agrees to reimburse the Issuing Bank promptly upon demand for its ratable share of any costs and expenses (including, without limitation, fees and expenses of counsel) payable by the Obligors under Section 9.04, to the extent that the Issuing Bank is not promptly reimbursed for such costs and expenses by the Obligors.

(c) For purposes of this Section 8.05, the Lender Parties’ respective ratable shares of any amount shall be determined, at any time, according to the sum of (i) the aggregate principal amount of the Advances outstanding at such time and owing to the respective Lender Parties and (ii) their respective Pro Rata Shares of the aggregate Available Amount of the Letter of Credit outstanding at such time; provided that the aggregate principal amount of Letter of Credit Advances owing to the Issuing Bank shall be considered to be owed to the Lenders ratably in accordance with their respective Commitments. The failure of any Lender Party to reimburse the Administrative Agent or the Issuing Bank, as the case may be, promptly upon demand for its ratable share of any amount required to be paid by the Lender Parties to the Administrative Agent or the Issuing Bank, as the case may be, as provided herein shall not relieve any other Lender Party of its obligation hereunder to reimburse the Administrative Agent or the Issuing Bank, as the case may be, for its ratable share of such amount, but no Lender Party shall be responsible for the failure of any other Lender Party to reimburse the Administrative Agent or the Issuing Bank, as the case may be, for such other Lender Party’s ratable share of such amount. Without prejudice to the survival of any other agreement of any Lender Party hereunder, the agreement and obligations of each Lender Party contained in this Section 8.05 shall survive the payment in full of principal, interest and all other amounts payable hereunder and under the other Loan Documents.

Section 8.06 Successor Administrative Agent The Administrative Agent may resign at any time by giving written notice thereof to the Lender Parties and the Borrowers; provided, however, that any removal of the Administrative Agent will not be effective until it has also been replaced as the Issuing Bank and released from all of its obligations in respect thereof. Upon any such resignation or removal, the Required Lenders shall have the right to appoint a successor Administrative Agent, provided, however, that if no Default or Event of Default shall have occurred and be continuing, subject to approval of the Borrowers (such approval not to be unreasonably withheld). If no successor Administrative Agent shall have been so appointed by the Required Lenders, and shall have accepted such appointment, within thirty (30) days after the retiring Administrative Agent’s giving of notice of resignation or the Required Lenders’ removal of the retiring Administrative Agent, then the retiring Administrative Agent may, on behalf of the Lender Parties, appoint a successor Administrative Agent, provided, however, that if no Default or Event of Default shall have occurred and be continuing, subject to approval of the Borrowers (such approval not to be unreasonably withheld), which shall be a commercial bank organized under the laws of the United States or of any State thereof and having a combined capital and surplus of at least $250,000,000. Upon the acceptance of any appointment as the Administrative Agent hereunder by a successor Administrative Agent and upon the execution and filing or recording of such financing statements, or amendments thereto, and such amendments or supplements to the Collateral Documents, and such other instruments or notices, as may be necessary or desirable, or as the Required Lenders may request, in order to continue the perfection of the Liens granted or purported to be granted by the Collateral Documents, such successor Administrative Agent shall succeed to and become vested with all the rights, powers, discretion, privileges and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations under the Loan Documents. If within forty five (45) days after written notice is given of the retiring Administrative Agent’s resignation or removal under this Section 8.06 no successor Administrative Agent shall have been appointed and shall have accepted such appointment, then on such 45th day (a) the retiring Administrative Agent’s resignation or removal shall become effective, (b) the retiring Administrative Agent shall thereupon be discharged from its duties and obligations under the Loan Documents and (c) the Required Lenders shall thereafter perform all duties of the retiring Administrative Agent under the Loan Documents until such time, if any, as

the Required Lenders appoint a successor Administrative Agent as provided above. After any retiring Administrative Agent’s resignation or removal hereunder as Administrative Agent shall have become effective, the provisions of this Article VIII shall inure to its benefit as to any actions taken or omitted to be taken by it while it was the Administrative Agent under this Agreement. Anything herein to the contrary notwithstanding, if at any time the Required Lenders determine that the Person serving as Administrative Agent is (without taking into account any provision in the definition of “Defaulting Lender” requiring notice from the Administrative Agent or any other party) a Defaulting Lender pursuant to clause (iv) of the definition thereof, the Required Lenders (determined after giving effect to Section 9.01) may by notice to the Borrowers and such Person remove such Person as Administrative Agent and , in consultation with the Borrowers, appoint a replacement Administrative Agent hereunder. Such removal will, to the fullest extent permitted by applicable law, be effective on the earlier of (i) the date a replacement Administrative Agent is appointed and (ii) the date thirty (30) days after the giving of such notice by the Required Lenders (regardless of whether a replacement Administrative Agent has been appointed).

Section 8.07 Delegation of Duties. The Administrative Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any other Loan Document by or through any one or more sub-agents appointed by the Administrative Agent. The Administrative Agent and any such sub-agent may perform any and all of its duties and exercise its rights and powers by or through their respective Related Parties (for purposes of this Section 8.07, “Related Parties” means, with respect to any Person, such Person’s Affiliates and the partners, directors, officers, employees, agents, trustees, administrators, managers, advisors and representatives of such Person and of such Person’s Affiliates). The exculpatory provisions of this Article shall apply to any such sub-agent and to the Related Parties of the Administrative Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the Facilities as well as activities as Administrative Agent. The Administrative Agent shall not be responsible for the negligence or misconduct of any sub-agents except to the extent that a court of competent jurisdiction determines in a final and nonappealable judgment that the Administrative Agent acted with gross negligence or willful misconduct in the selection of such sub-agents.

Section 8.08 Resignation of Issuing Bank In addition to the foregoing, if a Lender becomes, and during the period it remains, a Defaulting Lender, the Issuing Bank may, upon prior written notice to the Borrowers and the Administrative Agent, resign as Issuing Bank effective at the close of business New York time on a date specified in such notice (which date may not be less than thirty (30) days after the date of such notice); provided that such resignation by the Issuing Bank will have no effect on the validity or enforceability of any Letter of Credit then outstanding or on the obligations of the Borrowers or any Lender under this Agreement with respect to any such outstanding Letter of Credit or otherwise to the Issuing Bank.

Section 9.01 Amendments, Etc. No amendment or waiver of any provision of any Loan Document, nor consent to any departure by any Document Party therefrom, shall in any event be effective unless the same shall be in writing and signed by the Required Lenders, and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given; provided, however, that no amendment, waiver or consent shall, unless in writing and signed by all the Lenders affected by such amendment, waiver or comment, do any of the following: (a) waive any of the conditions specified in Section 3.01, (b) increase the Commitments of the Lenders or subject the Lenders to any additional obligations, (c) reduce the principal of, or interest on, the Advances, any Reimbursement Obligation or any fees or other amounts payable hereunder (provided that any Lender may waive, for itself, the timely payment of any amount owed to it arising from any claim by such Lender in respect of any indemnity obligation of the Borrowers to such Lender pursuant to Section 2.07 or 2.09), (d) postpone any date fixed for any payment of principal of, or interest on, the Advances or any fees or other amounts payable hereunder, (e) change the percentage of the Commitments or of the aggregate unpaid principal amount of the Advances or of the aggregate Available Amount of outstanding Letters of Credit, or the number of Lenders, that in each case shall be required for the Lenders or any of them to take any action hereunder, (f) reduce or limit the obligations of the Guarantor under Section 7.01 or otherwise limit any Obligor’s respective liability with respect to the Obligations owing to the Agents, the Lenders and the Issuing Banks, (g) amend this Section 9.01 or the definition of “Required Lenders” or (h) release all or substantially all of any cash collateral securing Reimbursement Obligations under the Letter of Credit, except to the extent otherwise permitted hereunder; and provided further that no amendment, waiver or consent shall, unless in writing and signed by the Issuing Bank, in addition to the Lenders required above to take such action, affect the rights or obligations of the Issuing Bank under this Agreement; provided further that no amendment, waiver or consent shall, unless in writing and signed by the Administrative Agent in addition to the Lenders required above to take such action, affect the rights or duties of the Administrative Agent in its capacity as the Administrative Agent, under this Agreement. Anything herein to the contrary notwithstanding, during such period as a Lender is a Defaulting Lender, to the fullest extent permitted by applicable law, such Lender will not be entitled to vote in respect of amendments and waivers hereunder and the Commitment and the outstanding Advances or other extensions of credit of such Lender hereunder will not be taken into account in determining whether the Required Lenders or all of the Lenders, as required, have approved any such amendment or waiver (and the definition of “Required Lenders” will automatically be deemed modified accordingly for the duration of such period); provided, that any such amendment or waiver that would increase or extend the term of the Commitment of such Defaulting Lender, extend the date fixed for the payment of principal or interest owing to such Defaulting Lender hereunder, reduce the principal amount of any obligation owing to such Defaulting Lender, reduce the amount of or the rate or amount of interest on any amount owing to such Defaulting Lender or of any fee payable to such Defaulting Lender hereunder, or alter the terms of this proviso, will require the consent of such Defaulting Lender.

(ii) The obligation of any Obligor in respect of any sum due from it in any Primary Currency to any Lender, the Issuing Bank or the Administrative Agent hereunder shall, notwithstanding any judgment or order in any other currency, be discharged only to the extent that on the Business Day following receipt by such Lender, the Issuing Bank or the Administrative Agent (as the case may be), of any sum adjudged to be so due in the Secondary Currency, such Lender, the Issuing Bank or the Administrative Agent (as the case may be) may in accordance with normal banking procedures purchase the applicable Primary Currency with the Secondary Currency; if the amount of the applicable Primary Currency so purchased is less than such sum due to such Lender, the Issuing Bank or the Administrative Agent (as the case may be) in the applicable Primary Currency, each Obligor agrees, as a separate obligation and notwithstanding any such judgment, to indemnify such Lender, the Issuing Bank or the Administrative Agent (as the case may be) against such loss, and if the amount of the applicable Primary Currency so purchased exceeds such sum due to any such Lender, the Issuing Bank or the Administrative Agent (as the case may be) in the applicable Primary Currency, such Lender, the Issuing Bank or the Administrative Agent (as the case may be) agrees to remit such excess to the applicable Obligor.

Section 9.05 Right of Set off Upon (a) the occurrence and during the continuance of any Event of Default and (b) the making of the request or the granting of the consent specified by Section 6.01 to authorize the Administrative Agent to declare the Advances due and payable pursuant to the provisions of Section 6.01 or otherwise with the consent of the Required Lenders, the Administrative Agent and each Lender Party and each of their respective Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and otherwise apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other indebtedness at any time owing by the Administrative Agent, such Lender Party or such Affiliate to or for the credit or the account of each Document Party against any and all of the Obligations of the Document Party now or hereafter existing under the Loan Documents to the Secured Parties, irrespective of whether the Administrative Agent or such Lender Party shall have made any demand under this Agreement or such Advance or Advances and although such Obligations may be unmatured; provided, however, that rights set forth in this Section 9.05 shall only apply in the event that the debt obligations of PDL and PBL under the PFA and the other debt obligations of the other obligors therein named have been paid or prepaid in full and all the commitments of the lenders under the PFA have been terminated. The Administrative Agent and each Lender Party agrees promptly to notify such Document Party after any such set off and application; provided, however, that the failure to give such notice shall not affect the validity of such set off and application; provided, further, that in the event that any Defaulting Lender exercises any such right of setoff, (x) all amounts so set off will be paid over immediately to the Administrative Agent for further application in accordance with the provisions of Section 2.17(a) and, pending such payment, will be segregated by such Defaulting Lender from its other funds and deemed held in trust for the benefit of the Administrative Agent, the Issuing Bank and the Lenders and (y) the Defaulting Lender will provide promptly to the

Administrative Agent a statement describing in reasonable detail the Obligations owing to such Defaulting Lender as to which it exercised such right of setoff. The rights of the Administrative Agent and each Lender Party and their respective Affiliates under this Section are in addition to other rights and remedies (including, without limitation, other rights of set off) that the Administrative Agent, such Lender Party and their respective Affiliates may have.

Section 9.06 Binding Effect This Agreement shall become effective when it shall have been executed by the Obligors and the Administrative Agent and the Administrative Agent shall have been notified by each Initial Lender Party that such Initial Lender Party has executed it, and thereafter shall be binding upon and inure to the benefit of the Obligors, the Administrative Agent and each Lender Party and their respective successors and assigns, except that no Obligor shall not have the right to assign its rights hereunder or any interest herein without the prior written consent of the Lender Parties.

(a) Each Lender, with the consent, not to be unreasonably withheld, of PDL, the Administrative Agent and the Issuing Bank, may, and, in the case of a Lender if demanded by the Borrowers (following a demand by such Lender pursuant to Section 2.09) upon at least five (5) Business Days’ notice to such Lender and the Administrative Agent, will, assign to one or more Persons all or a portion of its rights and obligations under this Agreement (including, without limitation, all or a portion of its Commitment or Commitments and the Advances owing to it); provided, however, that (i) each such assignment shall be of a constant, and not a varying, percentage of all rights and obligations under and in respect of the Facility, (ii) except in the case of an assignment to a Person that, immediately prior to such assignment, was a Lender or an assignment of all of a Lender’s rights and obligations under this Agreement, the amount of the Commitment of the assigning Lender being assigned pursuant to each such assignment (determined as of the date of the Assignment and Acceptance with respect to such assignment) shall in no event be less than $10,000,000 or an integral multiple of $1,000,000 in excess thereof, (iii) except in the case of an assignment of all of a Lender’s rights and obligations under this Agreement, the remaining Commitment of the assigning Lender shall in no event be less than $10,000,000, (iv) each such assignment shall be to an Eligible Assignee, (v) each such assignment made as a result of a demand by PDL pursuant to this Section 9.07(a) shall be arranged by PDL after consultation with the Administrative Agent and shall be either an assignment of all of the rights and obligations of the assigning Lender under this Agreement or an assignment of a portion of such rights and obligations made concurrently with another such assignment or other such assignments that together cover all of the rights and obligations of the assigning Lender under this Agreement, (vi) no Lender shall be obligated to make any such assignment as a result of a demand by PDL pursuant to this Section 9.07(a) unless and until such Lender shall have received one or more payments from either the Borrowers or one or more Eligible Assignees in an aggregate amount at least equal to the aggregate outstanding principal amount of the Advances owing to such Lender, together with accrued interest thereon to the date of payment of such principal amount and all other amounts then due and payable to such Lender under this Agreement and (vii) the parties to each such assignment shall execute and deliver to the Administrative Agent, for its acceptance and recording in the Register, an Assignment and Acceptance, and such Assignee will accede to the terms of the ICA (if not already a party thereto as a TI Bond Facility Creditor) and pay a processing and recordation fee of $3,500; provided

further that if such assignment is to an Eligible Assignee which is a direct or indirect wholly owned Subsidiary or Affiliate of any Lender or the controlling corporation of such Lender, no consent of the Borrower shall be required for such assignment. Upon such execution, delivery, acceptance and recording, from and after the effective date specified in each Assignment and Acceptance, (x) the assignee thereunder shall be a party hereto and, to the extent that rights and obligations hereunder have been assigned to it pursuant to such Assignment and Acceptance, have the rights and obligations of a Lender hereunder and (y) the Lender assignor thereunder shall, to the extent that rights and obligations hereunder have been assigned by it pursuant to such Assignment and Acceptance, relinquish its rights and be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all or the remaining portion of an assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto).

Notwithstanding the foregoing provisions of this Section 9.07(a), no such assignment will be made to any Defaulting Lender or its Subsidiaries, or any Person who, upon becoming a Lender hereunder, would constitute any of the foregoing Persons described in this clause.

In connection with any assignment of rights and obligations of any Defaulting Lender hereunder, no such assignment under this Section 9.07(a) will be effective unless and until, in addition to the other conditions thereto set forth herein, the parties to the assignment make such additional payments to the Administrative Agent in an aggregate amount sufficient, upon distribution thereof as appropriate (which may be outright payment, purchases by the assignee of participations or subparticipations, or other compensating actions, including funding, with the consent of the Borrowers and the Administrative Agent, the applicable pro rata share of Advances previously requested but not funded by the Defaulting Lender, to each of which the applicable assignee and assignor hereby irrevocably consent), to (x) pay and satisfy in full all payment liabilities then owed by such Defaulting Lender to the Administrative Agent, the Issuing Bank and each other Lender hereunder (and interest accrued thereon), and (y) acquire (and fund as appropriate) its full share of all Advances pro rata on the basis of its original Commitment. Notwithstanding the foregoing, in the event that any assignment of rights and obligations of any Defaulting Lender hereunder becomes effective under Applicable Law without compliance with the provisions of this paragraph, then the assignee of such interest will be deemed to be a Defaulting Lender for all purposes of this Agreement until such compliance occurs.

(b) By executing and delivering an Assignment and Acceptance, the Lender assignor thereunder and the assignee thereunder confirm to and agree with each other and the other parties hereto as follows: (i) other than as provided in such Assignment and Acceptance, such assigning Lender makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with the Loan Documents or the execution, legality, validity, enforceability, genuineness, sufficiency or value of the Loan Documents or any other instrument or document furnished pursuant thereto; (ii) such assigning Lender makes no representation or warranty and assumes no responsibility with respect to the financial condition of any Document Party or the performance or observance by any Document Party of any of its respective obligations under the Loan Documents or any other instrument or document furnished pursuant thereto; (iii) such assignee confirms that it has received a copy of this Agreement, together with copies of the financial statements referred to in

Section 4.01 and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into such Assignment and Acceptance; (iv) such assignee will, independently and without reliance upon the Administrative Agent, such assigning Lender or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement; (v) such assignee confirms that it is an Eligible Assignee; (vi) such assignee appoints and authorizes the Administrative Agent to take such action as agent on its behalf and to exercise such powers and discretion under the Loan Documents as are delegated to the Administrative Agent by the terms thereof, together with such powers and discretion as are reasonably incidental thereto; and (vii) such assignee agrees that it will perform in accordance with their terms all of the obligations that by the terms of this Agreement are required to be performed by it as a Lender or Issuing Bank, as the case may be.

(c) The Administrative Agent shall maintain at its address referred to in Section 9.02 a copy of each Assignment and Acceptance delivered to and accepted by it and a register for the recordation of the names and addresses of the Lenders and the Commitments of, and principal amount of the Advances owing to, each Lender from time to time (the “Register”). The entries in the Register shall be conclusive and binding for all purposes, absent manifest error, and the Obligors, the Administrative Agent and the Lenders may treat each Person whose name is recorded in the Register as a Lender hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Obligors, the Administrative Agent or any Lender at any reasonable time and from time to time upon reasonable prior notice.

(d) Upon its receipt of an Assignment and Acceptance executed by an assigning Lender and an assignee representing that it is an Eligible Assignee, together with the forms such assignee is required to deliver pursuant to subsection 2.09(e), the Administrative Agent shall, if such Assignment and Acceptance has been completed and is in substantially the form of Exhibit B hereto, (i) accept such Assignment and Acceptance, (ii) record the information contained therein in the Register and (iii) give prompt notice thereof to the Borrowers.

(e) Each Lender may sell participations to one or more banks or other entities (other than any Obligor or any of its Affiliates) in or to all or a portion of its rights and obligations under this Agreement (including, without limitation, all or a portion of its Commitment and the Advances owing to it); provided, however, that (i) such Lender’s obligations under this Agreement (including, without limitation, its Commitments) shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) such Lender shall remain the holder and sole payee of any such Advance for all purposes of this Agreement, (iv) the Obligors, the Administrative Agent and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under the Loan Documents and (v) any agreement pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver that requires the consent of each Lender directly affected thereby pursuant to the proviso to the first sentence of Section 9.01 and directly affects such participant.

(f) Any Lender may, in connection with any assignment or participation or proposed assignment or participation pursuant to this Section 9.07, disclose to the assignee or participant or proposed assignee or participant any information relating to the Obligors furnished to such Lender by or on behalf of the Obligors; provided that, prior to any such disclosure, the assignee or participant or proposed assignee or participant shall agree to preserve the confidentiality of any Confidential Information relating to the Obligors received by it from such Lender.

(g) Notwithstanding any other provision set forth in this Agreement, any Lender may at any time, without the consent of the Obligors or PIDWAL or the Administrative Agent, create a security interest in all or any portion of its rights under this Agreement and the other Loan Documents (including, without limitation, the Advances owing to it) in favor of any Federal Reserve Bank in accordance with Regulation A of the Board of Governors of the Federal Reserve System; provided that no such assignment of a security interest shall release a Lender from any of its obligations hereunder or substitute any Assignee for such Lender as a party hereto. For the avoidance of doubt, no such assignment to any Federal Reserve Bank shall require such Federal Reserve Bank to accede to any intercreditor arrangement entered into in connection with the PFA.

Section 9.08 Execution in Counterparts This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. Delivery by telecopier of an executed counterpart of a signature page to this Agreement shall be effective as delivery of an original executed counterpart of this Agreement.

Section 9.09 Confidentiality Neither the Administrative Agent nor any Lender Party shall disclose any Confidential Information to any Person without the consent of the Obligors, other than (a) subject to an agreement to comply with the provisions of this Section, to the Administrative Agent’s or such Lender Party’s Affiliates and their officers, directors, employees, agents and advisors and to actual or prospective Eligible 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 (including the National Association of Insurance Commissioners or any similar organization or quasi-regulatory authority) regulating such Lender Party, (d) to any rating agency when required by it, provided that, prior to any such disclosure, such rating agency shall undertake to preserve the confidentiality of any Confidential Information relating to the Obligors received by it from such Lender Party, (e) in connection with any litigation or proceeding to which the Administrative Agent or such Lender Party or any of its Affiliates may be a party or (f) in connection with the exercise of any right or remedy under this Agreement or any other Loan Document.

Section 9.10 Release of Collateral At such time as the Advances, the Reimbursement Obligations and the other obligations under the Loan Documents shall have been paid in full (other than contingent indemnification obligations), the Commitments have been terminated or expired and the Letter of Credit shall not be outstanding, the Collateral shall be released from the Liens created by the Collateral Documents, and the Collateral Documents and all obligations (other than those expressly stated to survive such termination) of the Administrative Agent and

each Document Party under the Collateral Documents shall terminate, and the Administrative Agent will, at the Obligors’ expense, execute and deliver to such Document Party such documents as such Document Party may reasonably request to evidence the release of such item of Collateral from the assignment and security interest granted under the Collateral Documents in accordance with the terms of the Loan Documents

Section 9.11 Patriot Act Notification Each Lender and the Administrative Agent (for itself and not on behalf of any Lender) hereby notifies the Obligors that pursuant to the requirements of the USA Patriot Act (Title III of Pub.L. 107-56 (signed into law October 26, 2001)) (the “Patriot Act”), it is required to obtain, verify and record information that identifies each Obligor, which information includes the name and address of such Obligor and other information that will allow such Lender or the Administrative Agent, as applicable, to identify such Obligor in accordance with the Patriot Act. Each Obligor shall, and shall cause each of its Subsidiaries to, provide, to the extent commercially reasonable, such information and take such actions as are reasonably requested by the Administrative Agent or any Lenders in order to assist the Administrative Agent and the Lenders in maintaining compliance with the Patriot Act.

(a) EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY AND UNCONDITIONALLY SUBMITS, FOR ITSELF AND ITS PROPERTY, TO THE NONEXCLUSIVE JURISDICTION OF ANY NEW YORK STATE COURT OR FEDERAL COURT OF THE UNITED STATES OF AMERICA SITTING IN NEW YORK CITY, AND ANY APPELLATE COURT FROM ANY THEREOF, IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS TO WHICH IT IS A PARTY, OR FOR RECOGNITION OR ENFORCEMENT OF ANY JUDGMENT, AND EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY AND UNCONDITIONALLY AGREES THAT ALL CLAIMS IN RESPECT OF ANY SUCH ACTION OR PROCEEDING MAY BE HEARD AND DETERMINED IN ANY SUCH NEW YORK STATE COURT OR, TO THE FULLEST EXTENT PERMITTED BY LAW, IN SUCH FEDERAL COURT. EACH OF THE PARTIES HERETO AGREES THAT A FINAL JUDGMENT IN ANY SUCH ACTION OR PROCEEDING SHALL BE CONCLUSIVE AND MAY BE ENFORCED IN OTHER JURISDICTIONS BY SUIT ON THE JUDGMENT OR IN ANY OTHER MANNER PROVIDED BY LAW. NOTHING IN THIS AGREEMENT SHALL AFFECT ANY RIGHT THAT ANY PARTY MAY OTHERWISE HAVE TO BRING ANY ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS IN THE COURTS OF ANY JURISDICTION.

EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, THE DEFENSE OF AN INCONVENIENT FORUM TO THE MAINTENANCE OF SUCH ACTION OR PROCEEDING IN ANY SUCH COURT.

(c) TO THE EXTENT THAT ANY OBLIGOR HAS OR HEREAFTER MAY ACQUIRE ANY IMMUNITY FROM JURISDICTION OF ANY COURT OF FROM ANY LEGAL PROCESS (WHETHER THROUGH SERVICE OR NOTICE, ATTACHMENT PRIOR TO JUDGMENT, ATTACHMENT IN AID OF EXECUTION OR OTHERWISE) WITH RESPECT TO ITSELF OR ITS PROPERTY, SUCH OBLIGOR HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, SUCH IMMUNITY IN RESPECT OF ITS OBLIGATIONS UNDER THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS TO WHICH IT IS A PARTY.

(d) Each Obligor irrevocably agrees to maintain an agent for service of process (reasonably satisfactory to the Administrative Agent) located in New York City and shall furnish to the Administrative Agent evidence on or before the Closing Date and thereafter from time to time that such agent shall have accepted such appointment for a period of time ending no earlier than one year after the Termination Date. Each Obligor irrevocably appoints C T Corporation System, 111 Eighth Avenue, New York, New York 10011, U.S.A., as its authorized agent (and any successor agent, the “Process Agent”) on which any and all legal process may be served in any action, suit or proceeding brought in any New York state or federal court. Each Obligor irrevocably agrees that service of process in respect of it upon the Process Agent, together with written notice of such service given to it in the manner provided for notices in Section 9.02, shall be deemed to be effective service of process upon it in any such action, suit or proceeding. Each Obligor agrees that the failure of the Process Agent to give notice to it of any such service shall not impair or affect the validity of such service or any judgment rendered in any such action, suit or proceeding based thereon. If for any reason the Process Agent named above shall cease to be available to act as such, each Obligor agrees to irrevocably appoint a replacement process agent in New York City, as its authorized agent for service of process, on the terms and for the purposes specified in this Section 9.12(d). Nothing in this Agreement or any other Loan Document will affect the right of any party hereto to serve process in any other manner permitted by applicable law or to obtain jurisdiction over any party or bring actions, suits or proceedings against any party in such other jurisdictions, and in such matter, as may be permitted by applicable law.

Section 9.13 GOVERNING LAW THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.
