From and after the Restatement Date, interest shall accrue on the Renewal Term Loan at the Applicable Rate, as further provided in Section 2.05. Interest may accrue on the Renewal Term Loan at the Base Rate or Eurodollar Rate, as further provided herein.

     2.02 Initial Funding of the Renewal Term Loan, Conversions and Continuations Thereof Loans.

     (a) The initial funding of the Renewal Term Loan on the Restatement Date, each conversion of all or a portion of the Renewal Term Loan from one Type to the other, and each continuation of all or a portion of the Renewal Term Loan as the same Type shall be made upon the Borrower’s irrevocable notice to the Administrative Agent, which may be given by telephone. Each such notice must be received by the Administrative Agent not later than noon, New York time, (i) three Business Days prior to the

Quest Eastern Amended
and Restated Credit Agreement

conversion to or continuation of Eurodollar Rate Loans, and (ii) one Business Day prior to the conversion of Eurodollar Rate Loans to Base Rate Loans, or the requested date of the initial funding of the Renewal Term Loan on the Restatement Date as a Base Rate Loan. Each such telephonic notice must be confirmed promptly by delivery to the Administrative Agent of a written Borrowing Notice, appropriately completed and signed by a Responsible Officer of the Borrower. The conversion to or continuation of Eurodollar Rate Loans shall be in a principal amount of $1,000,000 or a whole multiple of $1,000,000 in excess thereof. The Borrowing on the Restatement Date as a Base Rate Loan shall be in the amount of the Renewal Term Loan Commitment and any conversion to Base Rate Loans shall be in a principal amount of $1,000,000 or a whole multiple of $10,000 in excess thereof. Each Borrowing Notice (whether telephonic or written) shall specify (i) whether the Borrower is requesting a Borrowing on the Restatement Date, a conversion of all or a portion of the Renewal Term Loan from one Type to the other, or a continuation of all or a portion of the Renewal Term Loan as the same Type, (ii) the requested date of the Borrowing, conversion or continuation, as the case may be (which shall be a Business Day), (iii) the principal amount to be borrowed, converted or continued, (iv) the Type of Loans to be borrowed or converted, and (v) if applicable, the duration of the Interest Period with respect thereto. If the Borrower fails to specify a Type of Loan in a Borrowing Notice or if the Borrower fails to give a timely notice requesting a conversion or continuation, then the applicable Loan shall be made or continued as, or converted to, a Base Rate Loan. Any such automatic conversion to a Base Rate Loan shall be effective as of the last day of the Interest Period then in effect with respect to the applicable Eurodollar Rate Loan. If the Borrower requests a Borrowing of, conversion to, or continuation of a Eurodollar Rate Loan in any such Borrowing Notice, but fails to specify an Interest Period, it will be deemed to have specified an Interest Period of one month.

     (b) Following receipt of a Borrowing Notice, the Administrative Agent shall promptly notify the Lender of the applicable Borrowing, conversion or continuation, and if no timely notice of a conversion or continuation is provided by the Borrower, the Administrative Agent shall notify the Lender of the details of any automatic conversion to a Base Rate Loan described in the preceding subsection. In the case of the Borrowing on the Restatement Date, the Lender shall be deemed to have made the amount of its Renewal Term Loan available to the Borrower by making appropriate book entries to show the Original Term Loan, Revolving O&G Development Loan, First PIK Loan, Second PIK Loan and Interest Deferral Loan to have been refinanced in full and the Facility Fee has been paid in full.

     (c) Except as otherwise provided herein, a Eurodollar Rate Loan may be continued or converted only on the last day of the Interest Period for such Eurodollar Rate Loan. During the existence of an Event of Default, no Loan may be converted to or continued as Eurodollar Rate Loan without the consent of the Lender, and the Lender may demand that all or any portion of the then outstanding Eurodollar Rate Loan be converted immediately to a Base Rate Loan. The Administrative Agent shall promptly notify the Borrower and the Lender of the interest rate applicable to any Eurodollar Rate Loan upon determination of such interest rate. The determination of the Eurodollar Rate by the Administrative Agent shall be conclusive in the absence of manifest error.

     (d) After giving effect to the initial funding of the Renewal Term Loan, all conversions of the Renewal Term Loan from one Type to the other, and all continuations of the Renewal Term Loan as the same Type, there shall not be more than two (2) Interest Periods in effect at any given time with respect to the Renewal Term Loan.

     2.03 Prepayments.

Quest Eastern Amended
and Restated Credit Agreement

     (a) Optional Prepayments. The Borrower may, upon delivery of a Repayment Notice to the Administrative Agent, at any time or from time to time voluntarily prepay in whole or in part the Renewal Term Loan outstanding hereunder without premium or penalty; provided that (i) such notice must be received by the Administrative Agent not later than noon, New York time, (A) three Business Days prior to any date of prepayment of Eurodollar Rate Loans, and (B) the date of prepayment of Base Rate Loans; (ii) any prepayment of Eurodollar Rate Loans shall be in a principal amount of $1,000,000 or a whole multiple of $250,000 in excess thereof; and (iii) any prepayment of Base Rate Loans shall be in a principal amount of $25,000 or a whole multiple of $25,000 in excess thereof; provided that any prepayment may be in an aggregate amount that is equal to the entire Outstanding Amount of the Renewal Term Loan. Each such notice shall specify the date and amount of such prepayment and the Type(s) of Loans to be prepaid. The Administrative Agent will promptly notify the Lender of its receipt of each such notice. The Borrower shall make such prepayment and the payment amount specified in such notice shall be due and payable on the date specified therein. Any prepayment of a Eurodollar Rate Loan shall be accompanied by all accrued interest thereon, together with any additional amounts required pursuant to Section 3.05.

     (b) Mandatory Prepayments.

     (i) Dispositions. If any Net Cash Proceeds are received by the Borrower from one or more Dispositions but excluding any Disposition permitted by Section 7.07(a) and Section 7.07(c)), the Borrower shall immediately upon receipt of such Net Cash Proceeds repay the Obligations in an aggregate amount equal to 100% of such Net Cash Proceeds. Contemporaneously with such repayment, any amount payable by PEC to Lender pursuant to the Asset Sale Agreement will be paid (or in the case of the issuance of stock of PEC, delivered) to the Administrative Agent. If an Approved Disposition has occurred and PEC has performed its obligations under the Asset Sale Agreement, then Lender shall forgive any amount hereunder remaining unpaid.

     (ii) Insurance Proceeds. If pursuant to Section 6.07(b) any payments in excess of $1,000,000 are received by the Borrower in connection with any casualty insurance policy and the Administrative Agent elects to apply any portion of such payment as a mandatory prepayment of the Renewal Term Loan, Borrower shall immediately upon receipt of such insurance proceeds repay the Obligations in an aggregate amount equal to such portion in accordance with Section 6.07(b).

     (c) Prepayments: Interest/Consequential Loss. All prepayments under Section 2.03(a) shall be made together with accrued interest to the date of such prepayment on the principal amount prepaid.

     2.04 Repayment of Renewal Term Loan. The Borrower shall repay to the Lender on the Maturity Date the Renewal Term Loan, including all interest accrued on the Renewal Term Loan.

     2.05 Interest.

     (a) Subject to the provisions of subsection (b) below, (i) each Eurodollar Rate Loan shall bear interest on the outstanding principal amount thereof for each Interest Period at a rate per annum equal to the Eurodollar Rate for such Interest Period plus the Applicable Rate and (ii) each Base Rate Loan shall bear interest on the outstanding principal amount thereof from the applicable borrowing date at a rate per annum equal to the Base Rate plus the Applicable Rate

Quest Eastern Amended
and Restated Credit Agreement

     (b) If any amount payable by Borrower under the Loan Document is not paid when due (after giving effect to any applicable grace periods), whether at stated maturity by acceleration or otherwise, such amount shall thereafter bear interest at a fluctuating interest rate per annum at all times equal to the Default Rate, but in no event to exceed the Maximum Rate. Furthermore, while any Event of Default exists or after acceleration of the Renewal Term Loan (i) the Borrower shall pay interest on the principal amount of all outstanding Obligations at a fluctuating interest rate per annum at all times equal to the Default Rate, but in no event to exceed the Maximum Rate, and (ii) accrued and unpaid interest on past due amounts (including interest on past due interest, to the extent allowed by Law) shall be due and payable upon demand.

     (c) Interest on the Renewal Term Loan shall be due and payable in arrears on each Interest Payment Date applicable thereto and at such other times as may be specified herein. Interest hereunder shall be due and payable in accordance with the terms hereof before and after judgment, and before and after the commencement of any proceeding under any Debtor Relief Law.

     (d) If the designated rate applicable to the Renewal Term Loan exceeds the Maximum Rate, the rate of interest on such Loan shall be limited to the Maximum Rate, but any subsequent reductions in such designated rate shall not reduce the rate of interest thereon below the Maximum Rate until the total amount of interest accrued thereon equals the amount of interest which would have accrued thereon if such designated rate had at all times been in effect. In the event that at maturity (stated or by acceleration), or at final payment of the Outstanding Amount of the Renewal Term Loan, the total amount of interest paid or accrued is less than the amount of interest which would have accrued if such designated rates had at all times been in effect, then, at such time and to the extent permitted by Law, the Borrower shall pay an amount equal to the difference between (a) the lesser of the amount of interest which would have accrued if such designated rates had at all times been in effect and the amount of interest which would have accrued if the Maximum Rate had at all times been in effect, and (b) the amount of interest actually paid or accrued on such Outstanding Amount.

     2.06 Computation of Interest. Computation of interest on Base Rate Loans shall be calculated on the basis of a year of 365 or 366 days, as the case may be, and the actual number of days elapsed. Computation of interest on Eurodollar Rate Loans shall be calculated on the basis of a year of 360 days and the actual number of days elapsed, which results in a higher yield to the payee thereof than a method based on a year of 365 or 366 days. Interest shall accrue on each Loan for the day on which the Loan is made, and shall not accrue on a Loan, or any portion thereof, for the day on which the Loan or such portion is paid; provided that any Loan that is repaid on the same day on which it is made shall bear interest for one day.

     2.07 Evidence of Debt. The Renewal Term Loan made by the Lender shall be evidenced by one or more accounts or records maintained by the Lender and by the Administrative Agent in the ordinary course of business. The accounts or records maintained by the Administrative Agent and the Lender shall be conclusive absent manifest error of the amount of the Loans made by the Lender to the Borrower and the interest and payments thereon. Any failure so to record or any error in doing so shall not, however, limit or otherwise affect the obligation of the Borrower hereunder to pay any amount owing with respect to the Loans. In the event of any conflict between the accounts and records maintained by the Lender and the accounts and records of the Administrative Agent in respect of such matters, the accounts and records of the Lender shall control absent manifest error. Upon the request of the Lender made through the Administrative Agent, the Renewal Term Loan may be evidenced by a promissory note.

     2.08 Payments Generally.

Quest Eastern Amended
and Restated Credit Agreement

     (a) Subject to Sections 2.04 and 2.05, all payments to be made by the Borrower shall be made without condition or deduction for any counterclaim, defense, recoupment or setoff. Except as otherwise expressly provided herein, all payments by the Borrower hereunder shall be made to the Administrative Agent, for the account of the Lender, at the Administrative Agent’s Office in Dollars and in immediately available funds not later than noon, New York time, on the date specified herein. The Administrative Agent will promptly distribute to the Lender such payment in like funds as received by wire transfer to the Lender’s Lending Office. All payments received by the Administrative Agent after noon, New York time, shall be deemed received on the next succeeding Business Day and any applicable interest or fee shall continue to accrue.

     (b) Subject to the definition of “Interest Period,” if any payment to be made by the Borrower shall come due on a day other than a Business Day, payment shall be made on the next following Business Day, and such extension of time shall be reflected in computing interest or fees, as the case may be..

     (c) If no Event of Default exists and if no order of application is otherwise specified in the Loan Documents, payments and prepayments of the Obligations shall be applied first to accrued interest then due and payable on the Outstanding Amount of the Renewal Term Loan and then to the remaining Obligations in the order and manner as Borrower may direct.

     (d) If at any time insufficient funds are received by and available to the Administrative Agent to pay fully the Obligations, or if an Event of Default exists, any payment or prepayment shall be applied in the following order: (i) to the payment of enforcement expenses incurred by the Administrative Agent, including Attorney Costs; (ii) to the ratable payment of all fees, expenses and indemnities (including amounts payable under Article III) for which the Administrative Agent or Lender have not been paid or reimbursed in accordance with the Loan Documents (as used in this Section 2.08(d)(ii), a “ratable payment” for the Lender or the Administrative Agent shall be, on any date of determination, that proportion which the portion of the total fees, expenses and indemnities owed to the Lender or the Administrative Agent bears to the total aggregate fees, expenses and indemnities owed to the Lender and the Administrative Agent on such date of determination); (iii) to the payment of accrued and unpaid interest on the Outstanding Amount of, and to payment of the Outstanding Amount of, the Renewal Term Loan; and (iv) to the payment of the remaining Obligations, if any, in the order and manner the Lender deems appropriate.

     (e) Nothing herein shall be deemed to obligate the Lender to obtain the funds for the Renewal Term Loan in any particular place or manner or to constitute a representation by the Lender that it has obtained or will obtain the funds for the Renewal Term Loan in any particular place or manner.

ARTICLE III.
TAXES AND YIELD PROTECTION

     3.01 Taxes.

     (a) Any and all payments by the Borrower to or for the account of the Administrative Agent or the Lender under the Loan Document shall be made free and clear of and without deduction for any and all present or future taxes, duties, levies, imposts, deductions, assessments, fees, withholdings or similar charges, and all liabilities with respect thereto; excluding, in the case of the Administrative Agent and the Lender, taxes imposed on or measured by its net income (including any franchise taxes imposed

Quest Eastern Amended
and Restated Credit Agreement

on or measured by its net income), by the jurisdiction (or any political subdivision thereof) under the Laws of which the Administrative Agent or the Lender, as the case may be, is organized or maintains its Lending Office (all such non-excluded taxes, duties, levies, imposts, deductions, assessments, fees, withholdings or similar charges, and liabilities being hereinafter referred to as “Taxes”). If the Borrower shall be required by any Laws to deduct any Taxes from or in respect of any sum payable under the Loan Document to the Administrative Agent or the Lender, (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section), each of the Administrative Agent and the Lender receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions and (iii) the Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable Laws.

     (b) In addition, the Borrower agrees to pay any and all present or future stamp, mortgage, court or documentary taxes and any other excise or property taxes or charges or similar levies which arise from any payment made under the Loan Document or from the execution, delivery, performance, enforcement or registration of, or otherwise with respect to, the Loan Document (hereinafter referred to as “Other Taxes”).

     (c) If the Borrower shall be required to deduct or pay any Taxes or Other Taxes from or in respect of any sum payable under the Loan Document to the Administrative Agent or the Lender, the Borrower shall also pay to the Administrative Agent (for the account of the Lender) or to the Lender, at the time interest is paid, such additional amount that the Lender specifies as necessary to preserve the after-tax yield (after factoring in all taxes, including taxes imposed on or measured by net income) the Lender would have received if such Taxes or Other Taxes had not been imposed.

     (d) The Borrower agrees to indemnify the Administrative Agent and the Lender for (i) the full amount of Taxes and Other Taxes (including any Taxes or Other Taxes imposed or asserted by any jurisdiction on amounts payable under this Section) paid by the Administrative Agent and the Lender, and (ii) amounts payable under Section 3.01(c) and (iii) any liability (including penalties, interest and expenses) arising therefrom or with respect thereto, except to the extent such sums are determined by a court of competent jurisdiction by final and non-appealable judgment to have resulted from the gross negligence or willful misconduct of the Administrative Agent or the Lender, as applicable. Neither the Administrative Agent nor the Lender shall be entitled to receive any payment with respect to any indemnity claim under this Section 3.01 with respect to Taxes or Other Taxes that are incurred or accrued more than 180 days prior to the date such party gives notice and demand with respect thereto to the Borrower. Payment under this subsection (d) shall be made within 30 days after the date the Lender or the Administrative Agent makes a demand therefor.

     (e) As soon as practicable after any payment of indemnified Taxes or Other Taxes by the Borrower to a Governmental Authority, the Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

     (f) A Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the Law of the jurisdiction in which the Borrower is resident for tax purposes, or any treaty to which such jurisdiction is a party, with respect to payments hereunder or under any other Loan Document shall deliver to the Borrower (with a copy to the Administrative Agent), at the time or times prescribed by applicable Law or reasonably requested by the Borrower or the Administrative Agent, such properly

Quest Eastern Amended
and Restated Credit Agreement

completed and executed documentation prescribed by applicable Law, or reasonably requested by Borrower, as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, the Lender, if requested by the Borrower or the Administrative Agent, shall deliver such other documentation prescribed by applicable Law or reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the Administrative Agent to determine whether or not the Lender is subject to backup withholding or information reporting requirements.

     Without limiting the generality of the foregoing, in the event that the Borrower is resident for tax purposes in the United States, if Lender is a Foreign Lender it shall deliver to the Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) from time to time upon the request of the Borrower or the Administrative Agent, but only if Lender is legally entitled to do so, whichever of the following is applicable:

     (i) duly completed copies of Internal Revenue Service Form W-8BEN claiming eligibility for benefits of an income tax treaty to which the United States is a party;

     (ii) duly completed copies of Internal Revenue Service Form W-8ECI;

     (iii) in the case of Lender claiming the benefits of the exemption for portfolio interest under section 881(c) of the Code, (x) a certificate to the effect that Lender is not (A) a “bank” within the meaning of section 881(c)(3)(A) of the Code, (B) a “10 percent shareholder” of the Borrower within the meaning of section 881(c)(3)(B) of the Code, or (C) a “controlled foreign corporation” described in section 881(c)(3)(C) of the Code and (y) duly completed copies of Internal Revenue Service Form W-8BEN; or

     (iv) any other form prescribed by applicable Law as a basis for claiming exemption from or a reduction in United States Federal withholding tax duly completed together with such supplementary documentation as may be prescribed by applicable Law to permit the Borrower to determine the withholding or deduction required to be made.

     3.02 Illegality. If the Lender determines that any Change in Law has made it unlawful for the Lender or its applicable Lending Office to make, maintain or fund Eurodollar Rate Loans, or materially restricts the authority of the Lender to purchase or sell, or to take deposits of, Dollars in the applicable offshore Dollar market, or to determine or charge interest rates based upon the Eurodollar Rate, then, on notice thereof by the Lender to the Borrower through the Administrative Agent, any obligation of the Lender to make or continue Eurodollar Rate Loans or to convert Base Rate Loans to Eurodollar Rate Loans shall be suspended until the Lender notifies the Administrative Agent and the Borrower that the circumstances giving rise to such determination no longer exist. Upon receipt of such notice, the Borrower shall, upon demand from the Lender (with a copy to the Administrative Agent), prepay or, if applicable, convert all Eurodollar Rate Loans of the Lender to Base Rate Loans, either on the last day of the Interest Period thereof, if the Lender may lawfully continue to maintain such Eurodollar Rate Loans to such day, or immediately, if the Lender may not lawfully continue to maintain such Eurodollar Rate Loans. Upon any such prepayment or conversion, the Borrower shall also pay interest on the amount so prepaid or converted and all amounts due under Section 3.05 in accordance with the terms thereof due to such prepayment or conversion. Lender agrees to designate a different Lending Office if such designation will avoid the need for such notice and will not, in the reasonable judgment of the Lender, otherwise be materially disadvantageous to the Lender.

Quest Eastern Amended
and Restated Credit Agreement

     3.03 Inability to Determine Rates. If the Administrative Agent determines in connection with any request for a Eurodollar Rate Loan or a conversion to or continuation thereof that (a) Dollar deposits are not being offered to banks in the applicable offshore Dollar market for the applicable amount and Interest Period of such Eurodollar Rate Loan, or adequate and reasonable means do not exist for determining the Eurodollar Rate for such Eurodollar Rate Loan, or (b) if the Lender determines and notifies the Administrative Agent that the Eurodollar Rate for such Eurodollar Rate Loan does not adequately and fairly reflect the cost to the Lender of funding such Eurodollar Rate Loan, then the Administrative Agent will promptly notify the Borrower. Thereafter, the obligation of the Lender to make or maintain Eurodollar Rate Loans shall be suspended until the Administrative Agent revokes such notice. Upon receipt of such notice, the Borrower may revoke any pending request for a conversion or continuation of Eurodollar Rate Loans or, failing that, will be deemed to have converted such request into a request for a Base Rate Loans in the amount specified therein.

     3.04 Increased Cost and Reduced Return; Capital Adequacy; Reserves on Eurodollar Loans.

     (a) If the Lender determines that as a result of a Change in Law, or the Lender’s compliance therewith, there shall be any increase in the cost to the Lender of agreeing to make or making, funding or maintaining Eurodollar Rate Loans, or a reduction in the amount received or receivable by the Lender in connection with any of the foregoing (excluding for purposes of this subsection (a) any such increased costs or reduction in amount resulting from (i) Taxes or Other Taxes (as to which Section 3.01 shall govern), (ii) changes in the basis of taxation of overall net income or overall gross income by the United States or any foreign jurisdiction or any political subdivision of either thereof under the Laws of which the Lender is organized or has its Lending Office, and (iii) reserve requirements contemplated by Section 3.04(c) utilized, as to Eurodollar Rate Loans, in the determination of the Eurodollar Rate), then from time to time upon demand of the Lender (with a copy of such demand to the Administrative Agent), the Borrower shall pay to the Lender such additional amounts as will compensate the Lender for such increased cost or reduction.

     (b) If the Lender determines a Change in Law has the effect of reducing the rate of return on the capital of the Lender or any corporation controlling the Lender as a consequence of the Lender’s obligations hereunder (taking into consideration its policies with respect to capital adequacy and the Lender’s desired return on capital), then from time to time upon demand of the Lender (with a copy of such demand to the Administrative Agent), the Borrower shall pay to the Lender such additional amounts as will compensate the Lender for such reduction.

     (c) The Borrower shall pay to the Lender, as long as the Lender shall be required under regulations of the Board to maintain reserves with respect to liabilities or assets consisting of or including Eurocurrency funds or deposits (currently known as “Eurocurrency liabilities”), additional costs on the unpaid principal amount of each Eurodollar Rate Loan equal to the actual costs of such reserves allocated to such Loan by the Lender (as determined by the Lender in good faith, which determination shall be conclusive), which shall be due and payable on each date on which interest is payable on such Loan; provided the Borrower shall have received at least 15 days’ prior notice (with a copy to the Administrative Agent) of such additional interest from the Lender. If the Lender fails to give notice 15 days prior to the relevant Interest Payment Date, such additional interest shall be due and payable 15 days from receipt of such notice.

     (d) Failure or delay on the part of the Lender to demand compensation pursuant to this Section shall not constitute a waiver of the Lender’s right to demand such compensation; provided that

Quest Eastern Amended
and Restated Credit Agreement

the Borrower shall not be required to compensate the Lender pursuant to this Section for any increased costs or reductions incurred more than 180 days prior to the date that the Lender notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of the Lender’s intention to claim compensation therefor; provided further that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the 180-day period referred to above shall be extended to include the period of retroactive effect thereof.

     3.05 Compensation for Losses. Upon demand of the Lender (with a copy to the Administrative Agent) from time to time, the Borrower shall promptly compensate the Lender for and hold the Lender harmless from any loss, cost or expense incurred by it as a result of:

     (a) any continuation, conversion, payment or prepayment of any Loan other than a Base Rate Loan on a day other than the last day of the Interest Period for such Loan (whether voluntary, mandatory, automatic, by reason of acceleration, or otherwise); or

     (b) any failure by the Borrower to prepay, borrow, continue or convert any Loan other than a Base Rate Loan on the date or in the amount notified by the Borrower; including any loss of anticipated profits and any loss or expense arising from the liquidation or reemployment of funds obtained by it to maintain such Loan or from fees payable to terminate the deposits from which such funds were obtained. The Borrower shall also pay any customary administrative fees charged by the Lender in connection with the foregoing.

     For purposes of calculating amounts payable by the Borrower to the Lender under this Section 3.05, the Lender shall be deemed to have funded each Eurodollar Rate Loan made by it at the Eurodollar Rate for such Loan by a matching deposit or other borrowing in the applicable offshore Dollar interbank market for a comparable amount and for a comparable period, whether or not such Eurodollar Rate Loan was in fact so funded.

     3.06 Matters Applicable to all Requests for Compensation. A certificate of the Administrative Agent or the Lender claiming compensation under this Article III and setting forth the additional amount or amounts to be paid to it hereunder shall be conclusive in the absence of manifest error. In determining such amount, the Administrative Agent or the Lender may use any reasonable averaging and attribution methods.

     3.07 Survival. All of the Borrower’s obligations under this Article III shall survive payment in full of all the Obligations.

     3.08 Mitigation Obligations. If the Lender requests compensation under Section 3.04 or if the Borrower is required to pay any additional amount to the Lender or any Governmental Authority for the account of the Lender pursuant to Section 3.01, then the Lender shall use reasonable efforts to designate a different lending office for funding or booking its Eurodollar Loans or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of the Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 3.01 or Section 3.04, as the case may be, in the future and (ii) would not subject the Lender to any un-reimbursed cost or expense and would not otherwise be disadvantageous to the Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by the Lender in connection with any such designation or assignment.

The effectiveness of any such documents and signatures shall, subject to applicable Law, have the same force and effect as manually-signed originals and shall be binding on the Borrower, the Administrative Agent and the Lender. The Administrative Agent may also require that any such documents and signatures be confirmed by a manually-signed original thereof; provided, however, that the failure to request or deliver the same shall not limit the effectiveness of any facsimile document or signature.

     (c) Limited Use of Electronic Mail. Electronic mail and internet and intranet websites may be used only to distribute routine communications, such as financial statements and other information, and to distribute Loan Documents for execution by the parties thereto, and shall not be recognized hereunder for any other purpose.

     (d) Reliance by Administrative Agent and Lender. The Administrative Agent and the Lender shall be entitled to rely and act upon any notices purportedly given by or on behalf of the Borrower even if (i) such notices were not made in a manner specified herein, were incomplete or were not preceded or followed by any other form of notice specified herein, or (ii) the terms thereof, as understood by the recipient, varied from any confirmation thereof. The Borrower shall indemnify each Agent-Related Person and the Lender from all losses, costs, expenses and liabilities resulting from the reliance by such Person on each notice purportedly given by or on behalf of the Borrower. All telephonic notices to and other communications with the Administrative Agent may be recorded by the Administrative Agent, and each of the parties hereto hereby consents to such recording.

     10.03 No Waiver; Cumulative Remedies. No failure by the Lender or the Administrative Agent to exercise, and no delay by any such Person in exercising, any right, remedy, power or privilege hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any right, remedy, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege. The rights, remedies, powers and privileges herein or therein provided are cumulative and not exclusive of any rights, remedies, powers and privileges provided by law.

     10.04 Attorney Costs; Expenses and Taxes. The Borrower agrees (a) to pay or reimburse the Administrative Agent for all reasonable costs and expenses incurred in connection with the development, preparation, negotiation, syndication, administration and execution of this Agreement and the other Loan Documents, including the filing, recording, refiling or rerecording of any mortgage, any pledge agreement and any Security Agreement and/or any Uniform Commercial Code financing statements relating thereto and all amendments, supplements and modifications to any thereof and any and all other documents or instruments of further assurance required to be filed or recorded or refiled or rerecorded by the terms hereof or of any mortgage, any pledge agreement or any security agreement, and any amendment, waiver, consent or other modification of the provisions hereof and thereof (whether or not the transactions

contemplated hereby or thereby are consummated), and the consummation and administration of the transactions contemplated hereby and thereby, provided however that all such costs and expenses, Attorney Costs and FA Costs of the Administrative Agent and Lender relating to this Agreement shall not to exceed in the aggregate $50,000, and provided further, however, that all such costs and expenses, Attorney Costs and FA Costs of the Administrative Agent and Lender relating to this Agreement, together with all such costs and expenses, Attorney Costs and FA Costs as defined in, and as provided for in, the credit agreements of even date herewith relating to the $350 Million Borrowing Base Facility and the $15 Million Secured Pipeline Loan shall not exceed in the aggregate $1,000,000; and (b) to pay or reimburse the Administrative Agent and the Lender for all costs and expenses incurred in connection with the enforcement, attempted enforcement, or preservation of any rights or remedies under this Agreement or the other Loan Documents (including all such costs and expenses incurred during any workout or restructuring in respect of the Obligations and during any legal proceeding, including any proceeding under any Debtor Relief Law), including all Attorney Costs. The foregoing costs and expenses shall include all search, filing, recording, title insurance and appraisal charges and fees and taxes related thereto, and other out-of-pocket expenses incurred by the Administrative Agent and the cost of independent public accountants and other outside experts retained by the Administrative Agent or the Lender. The agreements in this Section shall survive the repayment of all the Obligations.

     10.05 Indemnification. Whether or not the transactions contemplated hereby are consummated, the Borrower agrees to indemnify, save and hold harmless each Agent-Related Person, the Administrative Agent, the Collateral Agent, the Lender and their respective Affiliates, directors, officers, employees, counsel, agents and attorneys-in-fact (collectively the “Indemnitees”) from and against: (a) any and all claims, demands, actions or causes of action that are asserted against any Indemnitee by any Person (other than the Administrative Agent or the Lender) relating directly or indirectly to a claim, demand, action or cause of action that such Person asserts or may assert against the Borrower, PESC or any of their respective officers or directors, arising out of or relating to, the Loan Documents, the use or contemplated use of the proceeds of the Renewal Term Loan, or the relationship of the Borrower, the Administrative Agent, the Collateral Agent and the Lender under this Agreement or any other Loan Document; (b) any and all claims, demands, actions or causes of action that may at any time (including at any time following repayment of the Obligations and the resignation of the Administrative Agent or the replacement of the Lender) be asserted or imposed against any Indemnitee by any Person or by the Borrower or PESC, arising out of or relating to, the Loan Documents, the use or contemplated use of the proceeds of the Renewal Term Loan, or the relationship of the Borrower, the Administrative Agent, the Collateral Agent and the Lender under this Agreement or any other Loan Document; (c) without limiting the foregoing, any and all claims, demands, actions or causes of action, judgments and orders, penalties and fines that are asserted or imposed against any Indemnitee, (i) under the application of any Environmental Law applicable to the Borrower or any of its properties or assets, including the treatment or disposal of Hazardous Substances on any of its properties or assets, (ii) as a result of the breach or non-compliance by the Borrower with any Environmental Law applicable to the Borrower, (iii) due to past ownership by the Borrower of any of its properties or assets or past activity on any of its properties or assets which, though lawful and fully permissible at the time, could result in present liability, (iv) due to the presence, use, storage, treatment or disposal of Hazardous Substances on or under, or the escape, seepage, leakage, spillage, discharge, emission or Release from, any of the properties owned or operated by the Borrower (including any liability asserted or arising under any Environmental Law), regardless of whether caused by, or within the control of, the Borrower, or (v) due to any other environmental, health or safety condition in connection with the Loan Documents; (d) any administrative or investigative proceeding by any Governmental Authority arising out of or related to a claim, demand, action or cause of action described in subsection (a), (b) or (c) above; and (e) any and all liabilities (including liabilities

Quest Eastern Amended
and Restated Credit Agreement

under indemnities), losses, costs, damages or expenses (including Attorney Costs and settlement costs) that any Indemnitee suffers or incurs as a result of the assertion of any foregoing claim, demand, action, cause of action or proceeding, or as a result of the preparation of any defense in connection with any foregoing claim, demand, action, cause of action or proceeding, in all cases, WHETHER OR NOT ARISING OUT OF THE STRICT LIABILITY OR NEGLIGENCE OF AN INDEMNITEE, and whether or not an Indemnitee is a party to such claim, demand, action, cause of action or proceeding (all the foregoing, collectively, the “Indemnified Liabilities”); provided that such indemnity shall not, as to any Indemnitees, be available to the extent that such liabilities, obligations, losses, damages, penalties, claims, demands, actions, judgments, suits, costs, expenses or disbursements result from the gross negligence or willful misconduct of such Indemnitee. The agreements in this Section shall survive repayment of the Obligations.

     10.06 Payments Set Aside. To the extent that the Borrower makes a payment to the Administrative Agent or the Lender, or the Administrative Agent or the Lender exercises its right of setoff, and such payment or the proceeds of such set-off or any part thereof is subsequently invalidated, declared to be fraudulent or preferential, set aside or required (including pursuant to any settlement entered into by the Administrative Agent or the Lender in its discretion) to be repaid to a trustee, receiver or any other party, in connection with any proceeding under any Debtor Relief Law or otherwise, then (a) to the extent of such recovery, the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such setoff had not occurred, and (b) the Lender agrees to pay to the Administrative Agent upon demand its applicable share of any amount so recovered from or repaid by the Administrative Agent, plus interest thereon from the date of such demand to the date such payment is made at a rate per annum equal to the Federal Funds Rate from time to time in effect.

     10.07 Successors and Assigns.

     (a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby, except that the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of the Lender and Lender may not assign or otherwise transfer any of its rights or obligations hereunder except (i) to an Eligible Assignee in accordance with the provisions of paragraph (b) of this Section, (ii) by way of participation in accordance with the provisions of paragraph (d) of this Section or (iii) by way of pledge or assignment of a security interest subject to the restrictions of paragraph (f) of this Section (and any other attempted assignment or transfer by any party hereto shall be null and void). Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby, Participants to the extent provided in paragraph (d) of this Section and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent and the Lender) any legal or equitable right, remedy or claim under or by reason of this Agreement.

     (b) Lender may at any time assign to one or more Eligible Assignees all or a portion of its rights and obligations under this Agreement at the time owing to it; provided that:

     except in the case of an assignment of the entire remaining amount of the assigning Lender’s Loans at the time owing to it or in the case of an assignment to an Affiliate of the Lender, the outstanding principal balance of the Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent or, if “Trade Date” is specified in the Assignment and Assumption, as of the Trade

Quest Eastern Amended
and Restated Credit Agreement

Date) shall not be less than $1,000,000, unless each of the Administrative Agent and, so long as no Event of Default has occurred and is continuing, the Borrower otherwise consent (Borrower’s consent not to be unreasonably withheld, conditioned or delayed) each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement with respect to the Loans assigned. The parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee of $3,500, and the Eligible Assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an administrative details form in form and substance satisfactory to the Administrative Agent.

     Subject to acceptance and recording thereof by the Administrative Agent pursuant to paragraph (c) of this Section, from and after the effective date specified in each Assignment and Assumption, the Eligible Assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, the Lender shall cease to be a party hereto) but shall continue to be entitled to the benefits of Sections 3.07, 10.04 and 10.05 with respect to facts and circumstances occurring prior to the effective date of such assignment. Any assignment or transfer by the Lender of rights or obligations under this Agreement that does not comply with this paragraph shall be treated for purposes of this Agreement as a sale by the Lender of a participation in such rights and obligations in accordance with paragraph (d) of this Section.

     (c) The Administrative Agent, acting solely for this purpose as an agent of the Borrower, shall maintain at one of its offices a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lender and principal amounts of the Loans owing to, the Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive absent manifest error, and the Borrower, the Administrative Agent and the Lender may treat each Person whose name is recorded in the Register pursuant to the terms hereof as the Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower and the Lender, at any reasonable time and from time to time upon reasonable prior notice.

     (d) Lender may at any time, without the consent of, or notice to, the Borrower or the Administrative Agent, sell participations to any Person (other than a natural person or the Borrower or any of the Borrower’s Affiliates) (each, a “Participant”) in all or a portion of the Lender’s rights and/or obligations under this Agreement (including all or a portion of its Loan owing to it); provided that (i) the Lender’s obligations under this Agreement shall remain unchanged, (ii) the Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the Borrower, the Administrative Agent and the other Lenders shall continue to deal solely and directly with the Lender in connection with the Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to which the Lender sells such a participation shall provide that the 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 or instrument may provide that the Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver that would (i) postpone any date upon which any payment of money is scheduled to be paid to such Participant, or (ii) reduce the principal, interest, fees or other amounts payable to such Participant. Subject to subsection (e) of this Section, the Borrower agrees that each Participant shall be entitled to the benefits of Sections 3.01 and 3.04 to the same extent as if it were the Lender and had acquired its interest by assignment pursuant

Quest Eastern Amended
and Restated Credit Agreement

to subsection (b) of this Section. To the extent permitted by Law, each Participant also shall be entitled to the benefits of Section 10.09 as though it were the Lender.

     (e) A Participant shall not be entitled to receive any greater payment under Section 3.01 or 3.04 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrower’s prior written consent. A Participant that would be a Foreign Lender if it were the Lender shall not be entitled to the benefits of Section 3.01 unless the Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 3.01 as though it were a Lender.

     (f) The Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement (including under its Renewal Term Loan Note, if any) to secure obligations of the Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank; provided that no such pledge or assignment shall release the Lender from any of its obligations hereunder or substitute any such pledgee or assignee for the Lender as a party hereto.

     (g) If the consent of the Borrower to an assignment or to an Eligible Assignee is required hereunder (including a consent to an assignment which does not meet the minimum assignment threshold specified in clause (i) of the proviso to the first sentence of Section 10.07(b)), the Borrower shall be deemed to have given its consent five Business Days after the date notice thereof has been delivered by the assigning Lender (through the Administrative Agent) unless such consent is expressly refused by the Borrower prior to such fifth Business Day.

     10.08 Confidentiality. The Lender agrees that it will not disclose without the prior consent of the Borrower (other than to directors, officers, employees, auditors, accountants, counsel or other professional advisors of the Administrative Agent or the Lender) any information with respect to the Borrower which is furnished pursuant to this Agreement; provided that the Lender may disclose any such information (a) as has become generally available to the public, (b) as may be required or appropriate in any report, statement or testimony submitted to or required by any municipal, state or federal regulatory body having or claiming to have jurisdiction over the Lender or submitted to or required by the Board or the Federal Deposit Insurance Corporation or similar organizations (whether in the United States or elsewhere) or their successors, (c) as may be required or appropriate in response to any summons or subpoena in connection with any litigation, (d) in order to comply with any law, order, regulation or ruling applicable to the Lender, (e) to any Eligible Assignee of or Participant in, or any prospective Eligible Assignee of or Participant in, any of its rights or obligations under this Agreement; provided that such Eligible Assignee or Participant or prospective Eligible Assignee or Participant executes an agreement containing provisions substantially similar to those contained in this Section 10.08, (f) in connection with the exercise of any remedy by the Lender if an Event of Default pertaining to the Loan Documents has occurred and is continuing, (g) in connection with any litigation involving the Lender pertaining to the Loan Documents, (h) to the Lender or the Administrative Agent, or (i) to any Affiliate of the Lender (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such information and obligated to keep such information confidential).

     10.09 Set-off. In addition to any rights and remedies of the Lender provided by Law, upon the occurrence and during the continuance of any Event of Default, the Lender is authorized at any time and from time to time, without prior notice to the Borrower, any such notice being waived by the Borrower to the fullest extent permitted by Law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held by, and other indebtedness at any time owing by, the

Quest Eastern Amended
and Restated Credit Agreement

Lender to or for the credit or the account of the Borrower against any and all Obligations owing to the Administrative Agent and the Lender, now or hereafter existing, irrespective of whether or not the Administrative Agent or the Lender shall have made demand under this Agreement or any other Loan Document and although such Obligations may be contingent or unmatured. Lender agrees promptly to notify the Borrower and the Administrative Agent after any such set-off and application made by the Lender; provided, however, that the failure to give such notice shall not affect the validity of such set-off and application.

     10.10 Interest Rate Limitation. Regardless of any provision contained in any Loan Document, neither the Administrative Agent nor the Lender shall ever be entitled to contract for, charge, take, reserve, receive, or apply, as interest on all or any part of the Obligations, any amount in excess of the Maximum Rate, and, if the Lender ever does so, then such excess shall be deemed a partial prepayment of principal and treated hereunder as such and any remaining excess shall be refunded to the Borrower. In determining if the interest paid or payable exceeds the Maximum Rate, the Borrower and the Lender shall, to the maximum extent permitted under applicable Law, (a) treat all Borrowings as but a single extension of credit (and the Lender and the Borrower agree that such is the case and that provision herein for multiple Borrowings is for convenience only), (b) characterize any nonprincipal payment as an expense, fee, or premium rather than as interest, (c) exclude voluntary prepayments and the effects thereof, and (d) amortize, prorate, allocate, and spread the total amount of interest throughout the entire contemplated term of the Obligations. However, if the Obligations are paid and performed in full prior to the end of the full contemplated term thereof, and if the interest received for the actual period of existence thereof exceeds the Maximum Amount, the Lender shall refund such excess, and, in such event, the Lender shall not, to the extent permitted by Law, be subject to any penalties provided by any Laws for contracting for, charging, taking, reserving or receiving interest in excess of the Maximum Amount.

     10.11 Counterparts. This Agreement may be executed in one or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. Delivery of an executed counterpart of a signature page of this Agreement by telecopy, facsimile, photocopy or by sending a scanned copy by electronic mail shall be effective as delivery of a manually executed counterpart of this Agreement. Any signature page of a counterpart may be detached therefrom without impairing the legal effect of the signatures thereon and attached to another counterpart identical in form thereto but having attached to it one or more additional signature pages signed by other parties.

     10.12 Integration. This Agreement, together with the other Loan Documents, comprises the complete and integrated agreement of the parties on the subject matter hereof and thereof and supersedes all prior agreements, written or oral, on such subject matter. In the event of any conflict between the provisions of this Agreement and those of any other Loan Document, the provisions of this Agreement shall control; provided that the inclusion of supplemental rights or remedies in favor of the Administrative Agent or the Lender in any other Loan Document shall not be deemed a conflict with this Agreement. Each Loan Document was drafted with the joint participation of the respective parties thereto and shall be construed neither against nor in favor of any party, but rather in accordance with the fair meaning thereof.

     10.13 Survival of Representations and Warranties. All representations and warranties made hereunder and in any other Loan Document or other document delivered pursuant hereto or thereto or in connection herewith or therewith shall survive the execution and delivery hereof and thereof. Such representations and warranties have been or will be relied upon by the Administrative Agent and the Lender, regardless of any investigation made by the Administrative Agent or the Lender or on their behalf and notwithstanding that the Administrative Agent or the Lender may have had notice or knowledge of

Quest Eastern Amended
and Restated Credit Agreement

any Default or Event of Default at the time of any Borrowing, and shall continue in full force and effect as long as the Renewal Term Loan or any other Obligation shall remain unpaid or unsatisfied.

     10.14 Severability. Any provision of this Agreement and the other Loan Documents to which the Borrower is a party that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions thereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

     10.15 Governing Law.

     (a) THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED ENTIRELY WITHIN SUCH STATE; PROVIDED THAT THE ADMINISTRATIVE AGENT AND LENDER SHALL RETAIN ALL RIGHTS ARISING UNDER UNITED STATES FEDERAL LAW.

     (b) THE BORROWER AGREES TO THIS SECTION 10.15(b). ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT MAY BE BROUGHT IN THE COURTS OF THE STATE OF NEW YORK SITTING IN THE BOROUGH OF NEW YORK OR OF THE UNITED STATES FOR THE SOUTHERN DISTRICT OF NEW YORK AND APPELLATE COURTS FROM ANY THEREOF, AND BY EXECUTION AND DELIVERY OF THIS AGREEMENT, THE BORROWER, THE ADMINISTRATIVE AGENT AND LENDER CONSENTS FOR ITSELF AND IN RESPECT OF ITS PROPERTY, TO THE NON-EXCLUSIVE JURISDICTION OF THOSE COURTS. THE BORROWER, THE ADMINISTRATIVE AGENT AND LENDER (1) IRREVOCABLY WAIVES ANY OBJECTION, INCLUDING ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE BRINGING OF ANY ACTION OR PROCEEDING IN SUCH JURISDICTION IN RESPECT OF ANY LOAN DOCUMENT OR OTHER DOCUMENT RELATED THERETO, AND (2) IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS OUT OF ANY OF THE AFOREMENTIONED COURTS IN ANY SUCH ACTION OR PROCEEDING BY THE MAILING OF COPIES THEREOF BY CERTIFIED MAIL, RETURN RECEIPT REQUESTED, POSTAGE PREPAID, AT ITS ADDRESS FOR NOTICES DESIGNATED HEREIN. THE BORROWER, THE ADMINISTRATIVE AGENT AND LENDER WAIVES PERSONAL SERVICE OF ANY SUMMONS, COMPLAINT OR OTHER PROCESS, WHICH MAY BE MADE BY ANY OTHER MEANS PERMITTED BY THE LAW OF SUCH STATE.

     10.16 Waiver of Right to Trial by Jury, Etc. EACH PARTY TO THIS AGREEMENT HEREBY (a) EXPRESSLY AND IRREVOCABLY WAIVES ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION ARISING UNDER ANY LOAN DOCUMENT OR IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES TO THE LOAN DOCUMENTS OR ANY OF THEM WITH RESPECT TO ANY LOAN DOCUMENT, OR THE TRANSACTIONS RELATED THERETO, IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER FOUNDED IN CONTRACT OR TORT OR OTHERWISE; AND EACH PARTY HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY, AND THAT ANY PARTY TO THIS AGREEMENT MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION WITH

     10.17 Release. As additional consideration for the execution, delivery and performance of this Agreement by the parties hereto and to induce the Administrative Agent, the Collateral Agent and the Lenders to enter into this Agreement, the Borrower warrants and represents to the Administrative Agent, the Collateral Agent and the Lender that no facts, events, statuses or conditions exist or have existed which, either now or with the passage of time or giving of notice, or both, constitute or will constitute a basis for any claim or cause of action against the Administrative Agent, the Collateral Agent or the Lender or any defense to (i) the payment of Obligations under the Note and/or the Loan Documents, or (ii) the performance of any of its obligations with respect to the Note and/or the Loan Documents.
