Payments that are not made when due by either Party shall bear interest at the rate set forth in Section 2.7. Any Failure by LDEL to give the notice pursuant to Section 2.1 shall not be deemed to be an Event of Default. If LDEL fails to give the notice required in Section 2.1 then, unless LDEL has given that notice, NOGC may make the determinations that LDEL was obligated to make and give the notice to LDEL, which determination and notice will have the same effect as the notice that was to have been given by LDEL. 2.3 No payment that is made or accepted by either Party pursuant to Section 2.2 and based on LDEL's notice (pursuant to Section 2.1) or NOGC's notice (pursuant to Section 2.2) shall constitute acceptance by either Party of the correctness of the calculations set forth in the notice.

The provisions of this Section 2.3 will survive any termination of this Agreement for a period of two years from the date of such termination. 2.4 All payments shall be made without any deduction or withholding for, or on account of any Tax unless that deduction or withholding is required by any law (as modified by the practice or regulation of any relevant governmental revenue authority) in effect at the time at which the payment is made. If an Obligated Party is required to deduct or withhold on account of any Tax, then the obligated Party will (a) pay to the relevant authority the full amount required to be deducted or withheld (including the full amount required to be deducted or withheld from any additional amount paid by the obligated Party to the Receiving Party under this Section 2.4) promptly upon the later of the last date on which that amount is required to be paid to the relevant authority and the date on which the Obligated Party receives notice that the amount (i) is payable to the relevant authority or (ii) has been assessed against the Receiving 5 6 Party; (b) promptly forward to the Receiving Party an official receipt (or a certified copy) or other documentation reasonably acceptable to the Receiving Party evidencing the payment to the relevant authority; and (c) if the Tax is an Indemnifiable Tax, pay to the Receiving Party, in addition to the payment to which the Receiving Party otherwise is entitled, such additional amount as is necessary to ensure that the net amount actually received by the Receiving Party (free and clear of Indemnifiable Taxes whether assessed against either Party) will equal the full amount that the Receiving Party would have received if no such deduction or withholding had been required. 2.5 The Receiving Party will deliver to the Obligated Party promptly upon request at any time (unless such delivery is reasonably likely to prejudice the Receiving Party's Tax position) any Tax certificates or documents reasonably requested to enable the Obligated Party to make payments without deduction or withholding for or on account of Taxes or to make such deduction or withholding at a reduced rate. If the Receiving Party subsequently receives a Tax credit resulting from a payment which includes an additional amount under Section 2.4, then promptly upon its receipt of that Tax credit, it will pay to the Obligated Party such amount as the Receiving Party reasonably determines will leave it (after such payment) in the same position as it would have been if no additional amount had been required to be paid. 2.6 If the Obligated Party would not be required to deduct or withhold for or on account of Taxes but for the failure by the Receiving Party to deliver any certificate or document referred to in Section 2.5, then the Obligated Party shall not be required to pay to the Receiving Party any additional amount referred to above. If, in such circumstances, a liability is assessed directly against the Obligated Party for not so deducting or withholding, then, except to the extent the Receiving Party has satisfied or then satisfies the liability resulting from such Tax, promptly upon demand therefor by the Obligated Party the Receiving Party will promptly pay to the Obligated Party the amount of the liability so assessed against it, including any related liability for penalties. 2.7 If either Party fails to pay the full amount payable by it when due, then interest on the unpaid portion shall accrue (both before and after judgment) at a rate equal to 1 1/2 percent per annum above the base rate from time to time of Citibank N.A. from the date on which the payment was due until the date of payment. If either Party fails to make timely payment of any amount due under this Agreement, then the other Party, in addition to any other remedy it may have, shall have the right to suspend its performance hereunder until such amount, including interest, has been paid. 2.8 All obligations arising out of this Agreement shall be paid and settled in cash. LDEL and NOGC shall have no obligation to deliver or receive any Commodity in its physical form. ARTICLE III.

(d) The occurrence of any event described -in (i) Sections 5.1(c)(i), (ii) or (iii) by or in respect of the Guarantor under the Guaranty (except that for the purpose of applying those three sections to the Guarantor the words "this Agreement" as used in those three sections shall read "the Guaranty") or (ii) Sections 5.1(c)(iv) through (xi), both inclusive, by or in respect of the Guarantor in each case shall constitute an Event of Default by LDEL. 5.2 If an event occurs such as (a) the adoption of, or any change in a law or regulation or in the interpretation or application thereof which makes it unlawful for a Party to perform any of its material obligations under this Agreement, or (b) it is reasonably foreseeable that a Party will be required on the next succeeding date on which a payment is due under this Agreement to pay to the other Party an additional amount in respect of an Indemnifiable Tax under Section 2.4 (except on account of interest on any past due payment), or (c) if the prices at which the Commodity may be bought and sold are fixed by federal, state or local government so that the Floating Price Determinant does not reflect the normal free market response to supply and demand which would exist if prices were not so fixed, or (d) there is an increase of more than 30 cents in the Daily Determination Price of the Commodity as is described in 9 10 paragraph (c) of Schedule B, then either Party, by appropriate notice may designate an Early Termination Date. 5.3 (a) Upon the designation of an Early Termination Date pursuant to Section 5.1, the terminating Party shall (i) promptly calculate an amount that is equal to the then present value of the total of all actual damages suffered and costs and expenses reasonably incurred and reasonably expected to be incurred by the terminating Party as a result of the occurrence of the Early Termination Date including, without limitation, any loss, cost or expense that would be incurred to preserve for the terminating Party the economic equivalent of the payment obligations of the Parties under this Agreement in respect of each Payment Date that is scheduled to occur after the Early Termination Date, which may be the costs and expenses to replace this Agreement with one or more swap agreements or arrangements which will provide the terminating Party with equivalent payment obligations in respect of each Payment Date, and (ii) send a statement of its calculation to the other Party. (b) On the Early Termination Date pursuant to Section 5.1, (i) the Defaulting Party shall owe to the Non-Defaulting Party the sum of the amount payable under Section 5.3(a), and the aggregate amount, if any, owed by the Defaulting Party pursuant to Article II up to the Early Termination Date if such amounts remain unpaid as of the Early Termination Date for any reason, including under the provisions of Section 2.2, and (ii) the Non-Defaulting Party shall owe the Defaulting Party the aggregate amount, if any, owed by the Non-Defaulting Party to the Defaulting Party pursuant to Article II up to the Early Termination Date if such amounts remain unpaid as of the Early Termination Date.

If the Parties fail to agree promptly upon the independent experts or if the independent experts agreed upon fail to mutually determine the matter promptly, then each Party shall promptly nominate one independent expert (if they have not been nominated previously) and the two experts so nominated shall promptly in turn nominate a third 10 11 independent expert and the determination of the third independent expert shall be binding upon the Parties save for fraud or manifest error. All of the independent experts shall be at the time at which they act under this Section 5.5 persons who are actually engaged in business as swap dealers in the Commodity. Each Party shall be entitled to (a) submit to the independent experts written briefs setting forth their views on the matter submitted for the determination; if copies of those briefs are forwarded to the other Party, and (b) make to the independent experts oral arguments, but only in the presence of the other Party. ARTICLE VI. FINANCIAL RESPONSIBILITY 6.1 On each Determination Day LDEL shall determine an Exposure Amount and shall send a notice of its determination to NOGC. 6.2 (a) If on any Determination Day a Net Exposure Amount exists for an Exposed Party, then, within seven Business Days after that Determination Date the Non-Exposed Party shall establish and thereafter maintain so long as there is a Net Exposure Amount for that Exposed Party a Letter of Credit from a major U.S. commercial bank acceptable to the Exposed Party (which shall not unreasonably withhold its acceptance) for the benefit of the Exposed Party that is equal to the Net Exposure Amount rounded to the next highest integral multiple of $500,000. (b) If on any Determination Day the aggregate amount of existing Letters of Credit that have been established by the Non-Exposed Party exceeds the Net Exposure Amount rounded to the next highest integral multiple of $500,000, then the Exposed Party shall do whatever the Non-Exposed Party reasonably requests as being necessary to authorize the appropriate reduction in the aggregate amount of the Letters Of Credit. (c) If on any Determination Day the aggregate amount of existing Letters of Credit is less than the Net Exposure Amount rounded to the next highest integral multiple of $500,000, then the Non-Exposed Party shall do whatever is necessary to cause an appropriate increase in the aggregate amount of the Letters of Credit or the issuance of additional Letters of Credit so that the aggregate amount of all Letters of Credit in favor of the Exposed Party equals the Net Exposure Amount rounded to the next highest integral multiple of $500,000. 6.3 Notwithstanding the foregoing, neither Party shall be required to provide a Letter of Credit in excess Of $10 million. 6.4 Within 120 days after the end of each of its fiscal years, (a) NOGC will provide to LDEL a copy of NOGC's audited financial statements (including, without limitation, its balance sheet and income statement) for that fiscal year, and (b) LDEL will deliver or cause to be delivered to NOGC a copy of LDNG's audited financial statements (including, without limitation, its balance sheet and income statement) for that fiscal year. In the event that at any time (a) NOGC has shareholders, equity below $125 million, positive working capital (current assets minus current liabilities, excluding deferred taxes and current maturities on long-term debt) below $1 million or total liabilities exceeding twice the amount of its shareholders, equity, or (b) LDNG has shareholders, equity below $20 million, positive working capital below $1 million or (c) the sum of LDNG's earnings before income taxes for any fiscal year of LDNG, plus depreciation, amortization and other items that were deducted in determining those earnings before taxes, but were not paid in cash, is less than one sixth of the amount at the end of that fiscal year of LDNG's total indebtedness for money borrowed which is not subordinated in right of payment to LDNG's obligations under the Guaranty or (d) any event that is described in Sections 5.1(c)(v)(vi)(vii)(viii) 11 12 or (ix) of this Agreement which if that event occurred with respect to a Party would constitute an Event of Default, occurs with respect to any entity ("Controlling Entity") that directly or indirectly controls the right to vote the majority of the shares of that Party or owns the majority of the equity interest in that Party or to LDNG (whether or not LDNG controls the right to vote the majority of the shares of LDEL or owns the majority of the equity interest in LDEL at the time at which that event occurs), then in any of those four events, and without affecting any other rights or remedies a Party may have under this Agreement because of the occurrence of any such event, the Letter of Credit to be provided by NOGC (if the events are those described in clause (a) or clause (d) of this sentence; but, as to clause (d), only to the extent the events relate to NGOC's Controlling Entity) or by LDEL (if the events are those described in clause (b), (c) or (d) of this sentence; but, as to clause (d), only to the extent the events relate to LDNG or to any other Controlling Entity of LDEL) under Section 6.2 shall equal the Exposure Amount and not the Net Exposure Amount, without giving effect to Section 6.3. 6.5 All of the financial statements referred to in Section 6.4 shall be prepared in accordance with generally accepted accounting principles in the United States as in effect at the time at which the financial statements are prepared. Each of the Parties will deliver or cause to be delivered to the other party upon the other Party's request, unaudited interim financial statements of the types described in Section 6.4 if and to the extent that those interim financial statements are prepared in the normal course of business of NOGC or LDNG, as the case may be. ARTICLE VII. ASSIGNMENT 7.1 Either Party may assign all or part of its rights to receive payments under this Agreement, subject to the agreement by the Parties to procedures which will ensure compliance by the assignor with the terms and obligations of this Agreement, otherwise no assignment of this Agreement or any of the rights or obligations under this Agreement will be made unless or until the Party seeking the assignment obtains the written consent thereto of the non-assigning Party. No transfer or succession to the interest of either Party under this Agreement, wholly or partially, will affect or bind the non-assigning Party until it has been furnished with written notice and a true copy of such assignment or with other proper proof that the claimant is legally entitled to such interest.

(a) The "Daily Average Price" shall be the sum of the Daily Determination Price for each calendar day during the Settlement Period (each, a "Calendar Day") divided by the number of Calendar Days in the Settlement Period. (b) The "Daily Determination Price" shall be: (i) For each Calendar Day when natural gas futures contracts (the "Gas Contracts") are being regularly traded on the New York Mercantile Exchange ("NYMEX"), the Daily Determination Price for each Calendar Day on which the Gas Contracts (x) were traded shall be the closing price of the one of the Gas Contracts the last trading date of which occurs (m) on that Calendar Day or (n) if no Gas Contracts have a last trading day on that Calendar Day, then the closing price on that Calendar Day of the Gas Contract having a last trading day most nearly following that Calendar Day (the "Prompt Contract") and (y) were not traded because of a temporary, short-term suspension of trading not exceeding five consecutive Calendar Days (Such as on a Saturday, Sunday or holiday on which NYMEX did not conduct trading) the closing price of the Prompt Contract on the most recent Calendar Day on which the Gas Contracts were traded (in either case, the "NYMEX Price"). (ii) For each Calendar Day for which the provisions of paragraph (b) (i) are not applicable to establish the Daily Determination Price, the Daily Determination Price Shall be the arithmetic average of the Index prices of spot gas delivered to pipelines for the following pipelines and markets, as each is reported in Inside F.E.R.C.'s Gas Market Report for the first day of the calendar month in which that Calendar Day fell: (q) ANR Pipeline Co., Louisiana; (r) Columbia Gulf Transmission Co., Louisiana; (s) Florida Gas Transmission Co., Louisiana; (t) Natural Gas Pipeline Co. of America, Louisiana; (u) Tennessee Gas Pipeline Co., Louisiana; (v) Trunkline Gas Co., Field Zone; (w) United Gas Pipe Line Co., Louisiana; (x) Texas Eastern Transmission Corp., Louisiana; (y) Texas Gas Transmission Corp., Zone SL; and (z) The Transcontinental Gas Pipe Line Corporation, the average price for Zones 2 and 3 (pooling points). If at any time the provisions of this paragraph b(ii) would be applicable but for the fact that Inside F.E.R.C. has not reported such an Index price for all the pipelines referred to above, but has reported such an Index price for at least [five] of such pipelines, then the Daily Determination Price shall be calculated as provided herein but using only such of those Index prices for such of those pipelines as were reported. (iii) For each Calendar Day for which the provisions of paragraph (b) (i) or (b) (ii) are not applicable to determine a Daily Determination Price, but for which Natural Gas Week (the "Report") reports "spot" prices for "Gulf Coast, Onshore" in the "Delivered to Pipeline" column in the Louisiana section under 17 18 the heading "Gas Price Report ($/MMBtu)", the Daily Determination Price shall be the Report Price, for the first day of the calendar month in which that Calendar Day fell, regardless of the date of the issue of the Report in which the report price is published. (iv) If the Daily Determination Price for any Calendar Day cannot be determined in the manner contemplated above by the tenth Business Day after a Period End Date, then the price for that Calendar Day to be used in calculating the Floating Price shall be the amount mutually determined by NOGC and LDEL to reflect most closely the average spot price for that Calendar Day for natural gas delivered to an interstate pipeline in the Louisiana market. (v) If, NOGC and LDEL are unable to agree upon the Daily Determination Price pursuant to paragraph (b)(iv) on or before the Payment Date, but in no event later than ten days after a Period End Date, then either Party may submit the matter to arbitration by written notification to the other Party of its desire to submit the matter to arbitration and in that notification shall name its arbitrator. The Party receiving a notification for arbitration shall notify the other Party of the name of its arbitrator within ten calendar days thereafter. The two arbitrators so named shall choose a third arbitrator. If the Party receiving the notification for arbitration fails to name an arbitrator within ten calendar days, then the arbitration shall be heard and determined by the single arbitrator which has been named. If two arbitrators are named but fail to name a third arbitrator, then the Chief Judge, United States District Court, Southern District of New York shall name the third arbitrator. The arbitration shall be conducted in accordance with the Commercial Rules of Arbitration of the American Arbitration Association. All arbitrators shall be individuals who are qualified by education, knowledge and experience to determine the issue being arbitrated. The decision of the arbitrators (a) shall be within the positions of the parties, (b) shall clearly state the Daily Determination Price, (c) if the arbitration was required because the sources of prices set forth in paragraph (b) are unavailable due to termination of trading of Gas Contract or termination of publication of prices, shall provide the parties with a method for calculating the Daily Determination Price for the remaining term of the Agreement, (d) shall be written and (e) shall be rendered within 15 days after all evidence has been submitted and arguments concluded. After the date of a notification of a Party's desire to submit a matter to arbitration until the matter is finally resolved by arbitration or by agreement of the parties, no payments attributable to the Settlement Period in question shall be due. Upon resolution of the matter, payment shall made within five business days and shall include interest accruing from the Payment Date until the date on which payment is made at a rate that is equal to the lesser of the then effective prime rate of interest for large U.S. Money Center Commercial Banks, published under "Money Rates" by The Wall Street Journal, and the maximum applicable non-usurious rate. (c) If any tax or similar charge that is imposed on the Commodity by any governmental body or agency after the date of the Agreement results in any increase in the Daily Determination Price that, but for that tax or charge would not have occurred at that time, then, for so long as that tax or charge and increase remain in effect, the Floating Price for each Settlement Period after the date on which that increase first 18 19 occurs shall be the Floating Price calculated using the Daily Determination Price for each Calendar Day of the Settlement Period less an amount which shall be the lesser, determined for each such Calendar Day, of: (i) one half of the amount of the increase in effect on such Calendar Day, and (ii) 15 cents per MMBtu. If that increase exceeds 30 cents per MMBtu at any time during the term of this Agreement, then that increase shall constitute an event on account of which either Party shall have the option to exercise its rights under Section 5.2 of the Agreement. If NOGC and LDEL are unable to agree if such an increase in the Daily Determination Price has occurred or upon the amount, duration or other aspects of such increase relevant to the calculation of the Floating Price, on or before the Payment Date then either Party may submit the matter to arbitration in the same manner and under the same procedures as are described in paragraph (b)(v). 19 20 SCHEDULE C EXPOSURE AMOUNT COMPUTATION On any Determination Day: (a) The Exposure Amount shall be equal to the positive number (in which case LDEL will be the Exposed Party) or the negative number (in which case NOGC will be the Exposed Party) that is calculated by adding each of the Settlement Period Exposure Amounts for that Determination Day. (b) The Settlement Period Exposure Amount for each Settlement Period shall be the positive or negative amount that is equal to the present value on the Determination Date of the Settlement Period Price Amount Difference for that Settlement Period from the Period End Date of that Settlement Period which is computed using a discount rate that is equal to the effective interest rate return that a purchaser would receive if it purchased on that Determination Date U.S. government securities that mature, as nearly as are available, on the Period End Date of that Settlement Period. (c) The Settlement Period Price Amount Difference for each Settlement Period shall be the product of multiplying (i) the Settlement Period Measurement Unit Price Difference for that Settlement Period by (ii) the Quantity per Settlement Period for that Settlement Period. (d) The Settlement Period Price Measurement Unit Difference for a Settlement Period shall be the difference of subtracting (i) the Escalated Collateral Base Price for that Settlement Period from (ii) the Fixed Price for that Settlement Period. (e) The Escalated Collateral Base Price for a Settlement Period shall be the Collateral Base Price on that Determination Day increased by compounding that Collateral Base Price from that Determination Day at the annual rate of eight percent on (i) each January 1 after that Determination Day to and including the first day of that Settlement Period and (ii) on the Period End Date of that Settlement Period. (f) The Collateral Base Price shall mean, (i) if there are futures contracts for natural gas ("Gas Contracts") regularly traded on the New York Mercantile Exchange ("NYMEX") on that Determination Day, the quotient of dividing (x) the sum of adding each of the closing prices on that Determination Day (or if there was no trading on the Determination Day because the NYMEX did not conduct trading on that Determination Day, the most recent day before the Determination Day on which there was trading conducted on NYMEX) of the 12 Gas Contracts for which the last trading day occurs most nearly after the month in which the Determination Day falls (except if a Gas Contract has a last trading day on that Determination date, that Gas Contract shall be the first of those 12 Gas Contracts) by (y) 12; or (ii) if there is no Gas Contract being traded on NYMEX on that Determination Day, then the prices that would be used to determine the Daily Determination Price under Schedule B if the prices of Gas Contracts are not available for determination of the Daily Determination Price shall be used to determine the Collateral Base Price in lieu of the prices of the Gas Contracts. 20 21 SCHEDULE D LETTER OF CREDIT FORMAT To: -------------------------------------------------- -------------------------------------------------- -------------------------------------------------- We hereby authorize you to draw at sign on ourselves for the account of for any sum or sums not exceeding in the aggregate _________________________.
