(c) For any Special Day, ▇▇▇▇▇▇ shall pay Fuel Manager the price negotiated by the parties for the Special Day Quantities delivered by Fuel Manager pursuant to the mutual agreement of the parties under Section 3.1(a) for such Special Day and actually taken and consumed by Elwood at the Facility.

(d) In addition to the price specified in Section 5.1(a) to be paid for Facility Consumption, on any Non-Special Days during Non-Summer Months ▇▇▇▇▇▇ shall pay to Fuel Manager sixteen cents (16 cents) per MMBtu multiplied by the ▇▇▇▇▇▇ Forecast Differential Quantities for the applicable Gas Day.

(e) In addition to the price specified in Section 5.1(a) to be paid for Facility Consumption, ▇▇▇▇▇▇ shall pay to Fuel Manager an amount equal to the positive difference between the Reference Price and the price set forth in Section 5.1(a) multiplied by the Incremental Intraday Quantities actually taken and consumed by ▇▇▇▇▇▇ at the Facility for the applicable Gas Day. If such amount is a negative number for a Gas Day, then Fuel Manager shall pay the absolute value of it to ▇▇▇▇▇▇ in accordance with Section 5.2(c).

(f) On any Gas Day in which ▇▇▇▇▇▇ takes and consumes less than one hundred percent (100 percent) of any agreed upon Special Day Quantities (and such failure is not excused by Force Majeure), then (A) ▇▇▇▇▇▇ shall reimburse Fuel Manager for the positive difference, if any, between the price in effect for such quantities of Gas and the Daily Deficiency Price (as defined below) multiplied by the quantities of Gas ▇▇▇▇▇▇ failed to purchase, and (B) Fuel Manager shall reimburse ▇▇▇▇▇▇ for the positive difference, if any, between the Daily Deficiency Price and the price in effect for such quantities of Gas multiplied by the quantities of Gas ▇▇▇▇▇▇ failed to take and consume.

failed to purchase below ninety-five percent (95 percent) of the Incremental Intraday Quantities, and (B) Fuel Manager shall reimburse ▇▇▇▇▇▇ for the positive difference, if any, between the Daily Deficiency Price and the price in effect for such quantities of Gas multiplied by the quantities of Gas ▇▇▇▇▇▇ failed to take and consume below ninety-five percent (95 percent) of the Incremental Intraday Quantities. As used in this Subsection (g), the "Daily Deficiency Price" shall mean the Gas Daily Average Price for transactions conducted on the following Gas Day as reported in Gas Daily on the second Gas Day following the Gas Day of the purchase deficiency plus four cents (4 cents).

(h) On any Gas Day in which ▇▇▇▇▇▇ takes and consumes less than ninety percent (90 percent) of any ▇▇▇▇▇▇ Forecast Differential Quantities (and such failure is not excused by Force Majeure), then (A) ▇▇▇▇▇▇ shall reimburse Fuel Manager for the positive difference, if any, between the price in effect for such quantities of Gas and the Daily Deficiency Price (as defined below) multiplied by the quantities of Gas ▇▇▇▇▇▇ failed to take and consume below ninety percent (90 percent) of the ▇▇▇▇▇▇ Forecast Differential Quantities and (B) Fuel Manager shall reimburse ▇▇▇▇▇▇ for the positive difference, if any, between the Daily Deficiency Price and the price in effect for such quantities of Gas multiplied by the quantities of Gas ▇▇▇▇▇▇ failed to purchase below ninety percent (90%) of the ▇▇▇▇▇▇ Forecast Differential Quantities. As used in this Subsection (h), the "Daily Deficiency Price" shall mean the Gas Daily Average Price for transactions conducted on the following Day as reported in Gas Daily on the second Gas Day following the Gas Day of the purchase deficiency plus sixteen cents (16 cents).

(i) ▇▇▇▇▇▇ shall pay to Nicor Gas when due all fees and charges, including taxes and surcharges, due under the Nicor T&B Agreement, subject to Fuel Manager's obligation to reimburse ▇▇▇▇▇▇ for some of such charges as provided in Section 5.2.

(j) As compensation for its performance of the duties and obligations set forth in Section 3.2, ▇▇▇▇▇▇ shall pay Fuel Manager the sum of Sixty Five Thousand Dollars ($65,000) per month for each of the Summer Months and Ten Thousand Dollars ($10,000) per month for each of the Non-Summer Months.

(k) As compensation for the carrying costs associated with the Gas purchased by Fuel Manager pursuant to Section 4.5(a), ▇▇▇▇▇▇ shall pay Fuel Manager each month during the Term of this Agreement a carrying charge determined using an annual interest rate of four percent (4 percent) and the purchase price determined pursuant to Section 4.5(a). The monthly carrying charge shall equal the purchase price determined pursuant to Section 4.5(a) mulitplied by 0.003333 (four percent divided by 12).

(l) If and when any amount is received, as either an actual payment or a credit, by ▇▇▇▇▇▇ from Nicor under Section 10 (reduction of MMDN rights) of the Nicor T&B Agreement with respect to any Month during the term hereof, ▇▇▇▇▇▇ shall pay such amounts to Fuel Manager, which shall be due and payable with the next payment otherwise due hereunder. Fuel Manager also shall receive the benefit of the limitation on application of Nicor's Unaccounted-for Gas percentage contained in Section 9 of the Nicor T&B Agreement.

(m) The Gas purchased and sold hereunder and consumed by ▇▇▇▇▇▇ at the Facility shall be deemed delivered in the following order: (i) Special Day Quantities agreed upon pursuant to Section 3.1(a); (ii) Incremental Intraday Quantities agreed upon

pursuant to Section 3.1(a); (iii) ▇▇▇▇▇▇ Forecast Differential Quantities; and (iv) all other Gas delivered under this Agreement.

5.2 Payments by Fuel Manager.

(a) Fuel Manager shall reimburse ▇▇▇▇▇▇ in accordance with Section 7.2 for the billed charges under the following sections of the Nicor T&B Agreement to the extent that (i) such charges are incurred with respect to Non-Special Days, (ii) ▇▇▇▇▇▇ has provided notices and information in accordance with the Communications Protocol, (iii) such charges are not the result of Elwood's failure to operate the Facility as provided in Section 4.4, (iv) such charges are not the result of total quantities consumed at the Facility having exceeded the Firm MDQ, and (v) ▇▇▇▇▇▇ has not declared an event of Force Majeure or such charges are incurred due to a "Unit trip" (as that term is used in Exhibit A).

(A) Forecast Variance Charges (Section 4(e) of the Nicor T&B Agreement) attributable to the portion of the variance up to (i) 241,600 MMBtu/d in the Summer Months or (ii) 67,400 MMBtu/d plus any Incremental Intraday Quantities agreed upon pursuant to Section 3.1(a) in the Non-Summer Months.

(B) Delivery Variance Charges (Section 4(c) of the Nicor T&B Agreement) except to the extent such charges are attributable to volumes in excess of the Firm MDQ;

(C) Storage Inventory Overrun Charges and/or Excess Storage Charges but only those Excess Storage Charges assessed because the highest daily quantity in storage is in excess of 951,500 MMBtu's and/or Balancing and Storage Service charges attributable to Incremental Intraday Quantities (Sections 4(f) and 4(g) of the Nicor T&B Agreement); and

(D) Charges for Requested Authorized Use and Unauthorized Use (Sections 4(i) and (j) of the Nicor T&B Agreement).

Items (A), (B), (C) and (D) are collectively referred to herein as the "Fuel Manager's T&B Charges." The Fuel Manager's T&B Charges may be (i) applied by ▇▇▇▇▇▇ as a credit to Fuel Manager's invoices, effectively netting Fuel Manager's T&B Charges against the amounts owed Fuel Manager under this Agreement or (ii) invoiced by ▇▇▇▇▇▇ directly to Fuel Manager thereby requiring Fuel Manager to remit such funds to ▇▇▇▇▇▇ upon presentation of an invoice. Additionally, Fuel Manager shall be responsible for Nicor's Unaccounted-for Gas charges with respect to storage injections; provided, however, should ▇▇▇▇▇▇ fail to take any agreed upon Incremental Intraday Quantities and/or Special Day Quantities and Fuel Manager injects such Incremental Intraday Quantities and/or Special Day Quantities not taken by ▇▇▇▇▇▇, ▇▇▇▇▇▇ shall credit to (or pay to) Fuel Manager an amount toward the Nicor Unaccounted-for Gas charges calculated as the product of the quantity of Incremental Intraday Quantities and/or Special Day Quantities that are not taken by ▇▇▇▇▇▇ and are injected into storage by Fuel Manager multiplied by Nicor's effective Unaccounted-for Gas percentage multiplied by the price for the Incremental Intraday Quantities and/or Special Day Quantities agreed to by the parties pursuant to Section 3.1(a). Notwithstanding the foregoing, on Special Days, Fuel Manager will not be responsible for Fuel Manager's T&B Charges except (x) for those T&B Charges associated with Special Day Quantities where the parties have agreed on a price and volume pursuant to Section 3.1(a), and (y) to the extent that Fuel Manager's

T&B Charges are incurred as a direct result of Fuel Manager failing to deliver to the Receipt Point on such Special Day the Special Day Quantities agreed to by the parties except to the extent such failure to deliver is caused by an event of Force Majeure that occurs after the parties have agreed to a quantity and price for such Special Day under Section 3.1(a); provided, however, that Fuel Manager shall in no event be responsible on a Special Day for the Fuel Manager T&B Charges described in (D) above.

(b) Fuel Manager shall pay when due to a Seller or reimburse ▇▇▇▇▇▇ if a Seller directly invoices ▇▇▇▇▇▇, all charges under any Purchase Agreements entered into by Fuel Manager on its own account or as Agent.

(c) Fuel Manager shall pay ▇▇▇▇▇▇ the amount described in the last sentence of Section 5.1(e), if any, for each Gas Day of a month.

In the event of such termination, all costs associated with unwinding or terminating Purchase Agreements shall be borne equally by the parties.

10.3 Fuel Manager Default.

(a) Each of the following shall constitute a "Fuel Manager Event of Default":

(i) Fuel Manager shall default in the performance of any of its covenants or obligations under this Agreement (other than those specified in Section 10.3(a)(iv), which shall be exclusively governed by that Section, and other than a Gas delivery obligation which shall be exclusively governed by Section 10.3(c)) and shall fail to cure such default within five (5) days after receiving written notice from ▇▇▇▇▇▇;

(ii) Default occurs under the Fuel Manager Guaranty;

(iii) Liquidation (not as defined in this Agreement), dissolution, receivership, insolvency, bankruptcy, assignment for the benefit of creditors, reorganization, arrangement, composition or readjustment or other similar proceeding affecting the status, composition, identity, existence, assets or obligations of Fuel Manager or Fuel Manager Guarantor, or the disaffirmance or termination of any of Fuel Manager's or Fuel Manager Guarantor's covenants or obligations under this Agreement, or the Fuel Manager Guaranty, as applicable, in or as a result of any such proceeding;

ARTICLE XIV
FORCE MAJEURE

14.1 Force Majeure Generally. Except with respect to payment obligations due from one party to the other hereunder, neither party shall be responsible or liable for its failure to perform any obligation hereunder, or be deemed in breach hereof, to the extent such failure to perform is due to the occurrence of an event of "Force Majeure," as that term is defined in Section 14.2 as applicable to such party, provided that:

(a) The non-performing party (i) gives the other party prompt verbal notice of the occurrence and (ii) within forty-eight (48) hours of the beginning of the occurrence or by 5:00 p.m. Central Clock Time on the next Business Day after the beginning of the occurrence, whichever is the later to occur, gives the other party written notice describing the particulars of the occurrence;

(b) The suspension of performance is of no greater scope and of no longer duration than is required by the Force Majeure;

(d) When the non-performing party is able to resume performance of its obligations under this Agreement, that party shall give the other party written notice to that effect; and

(e) The Force Majeure was not caused by or connected with any negligent or intentional acts, errors, or omissions, or failure to comply with any law, rule, regulation, order or ordinance by the party invoking the Force Majeure.

14.2 Definition of Force Majeure.

(a) In the case of ▇▇▇▇▇▇, "Force Majeure" under this Agreement means any delay in the performance of its obligations hereunder due solely to circumstances beyond its reasonable control, and that could not have been prevented by due diligence, of ▇▇▇▇▇▇, including without limitation: acts of God; weather-related events affecting an entire geographic region; strikes or other labor difficulties; war; riots; requirements, actions, or failures to act on the part of governmental authorities or changes in the law or applicable regulations subsequent to the date hereof preventing performance; inability despite due diligence to obtain or renew required licenses; accident; earthquake, sabotage; or fire.

(b) In the case of Fuel Manager, "Force Majeure" under this Agreement means only and is limited to declarations of force majeure by Nicor Gas under the Nicor T&B Agreement, or by any of NBPL, APL, NGPL or any pipeline upstream of such pipelines under its tariff or transportation agreement, or by Peoples Gas under the Peoples Gas T&B Agreement, as the term "force majeure" is defined and applied in those documents, or a default by Nicor Gas under the Nicor T&B Agreement not due to Fuel Manager's failure to fulfill its responsibilities under this Agreement, or a restriction on storage or bank rights under the Nicor T&B Agreement not due to Fuel Manager's failure to fulfill its responsibilities under this Agreement, if and only to the extent that such declaration(s) or restriction(s) result(s) in a curtailment of transportation or storage service that directly impact Fuel Manager's ability to execute its responsibilities under this Agreement and are beyond the reasonable control of, and could not have been prevented by the due diligence of, Fuel Manager; provided, however, that if a declaration of force majeure by any of NBPL, APL, NGPL is based on an outage of its pipeline system upstream of its interconnection with the facilities of Peoples Gas or Nicor Gas ("Pipeline Outage Condition") or if a declaration of force majeure by Nicor Gas is based on an outage of its pipeline system used to provide service to ▇▇▇▇▇▇ ("Nicor Gas Outage Condition") the parties agree that such Pipeline Outage Condition or Nicor Gas Outage Condition, as applicable, shall have the effect of converting Fuel Manager's obligation to provide a firm gas supply into a reasonable efforts obligation for the duration of the Pipeline Outage Condition or Nicor Gas Outage Condition, as applicable, and Fuel Manager shall be entitled to recover from ▇▇▇▇▇▇ (but only to the extent such costs have been approved by ▇▇▇▇▇▇ in advance) Fuel Manager's costs relating to Fuel Manager's performance during such Pipeline Outage Condition or Nicor Gas Outage Condition, as applicable. Notwithstanding the foregoing, if Fuel Manager uses its reasonable efforts to perform during a Pipeline Outage Condition or Nicor Gas Outage Condition, as applicable and, despite Fuel Manager's reasonable efforts and the exercise of Fuel Manager's due diligence, is unable to provide firm gas supply pursuant to this Agreement due to such

Pipeline Outage Condition or Nicor Gas Outage Condition, as applicable, then such event shall qualify as a "Force Majeure" for Fuel Manager under this Agreement, subject to the other limitations on Force Majeure set forth in this Article XIII of this Agreement. Notwithstanding the foregoing provisions of this subsection (b), the parties agree that if a declaration of force majeure by Nicor Gas under the Nicor T&B Agreement results in the occurrence of a Special Day, such Nicor Gas declaration will not excuse the parties' obligations to deliver and receive on such Special Day the quantity of Gas subsequently agreed upon pursuant to Section 3.1(a), but that such obligations may be excused by a subsequent declaration of force majeure by Nicor Gas.

14.3 Exclusions from Force Majeure.

Notwithstanding the foregoing, the term Force Majeure does not include (i) changes in market conditions that affect the cost of Gas or any alternate supplies of Gas or (ii) Gas supply or transportation interruptions, except to the extent that Gas is unavailable generally on the NBPL, APL, NGPL, Nicor Gas or Peoples Gas systems at any price.

14.4 Extended Force Majeure.

In no event will any condition of Force Majeure extend this Agreement beyond its stated Term. If any condition of Force Majeure delays a party's performance for a time period greater than thirty (30) days, the party not delayed by such Force Majeure may terminate this Agreement, without further obligation; provided, however, that if the Force Majeure cannot be overcome within such thirty (30) days with the exercise of reasonable diligence, the party not delayed shall grant an additional reasonable period of time in which to overcome such Force Majeure. In no event will such additional reasonable period of time exceed three (3) months.
