AMOUNTS AND TERMS OF THE COMMITMENTS

SECTION 2.01 Commitments. Each Lender severally agrees, on the terms and conditions hereinafter set forth, to (a) make Advances to any Borrower and (b) to participate in Facility LCs issued upon the request of any Borrower, in each case from time to time during the period from the date hereof to the Commitment Termination Date for such Borrower, in an aggregate amount not to exceed such Lender’s Commitment Amount as in effect from time to time; provided that (i) the aggregate principal amount of all Advances by such Lender to any

Borrower shall not exceed such Lender’s Pro Rata Share of the aggregate principal amount of all Advances to such Borrower; (ii) such Lender’s participation in Facility LCs issued for the account of any Borrower shall not exceed such Lender’s Pro Rata Share of all LC Obligations of such Borrower; (iii) the Outstanding Credit Extensions to Exelon shall not at any time exceed the Exelon Sublimit; (iv) the Outstanding Credit Extensions to ComEd shall not any time exceed the ComEd Sublimit; (v) the Outstanding Credit Extensions to PECO shall not at any time exceed the PECO Sublimit; (vi) the Outstanding Credit Extensions to Genco shall not at any time exceed the Genco Sublimit; and (vii) the LC Obligations of all Borrowers collectively shall not at any time exceed the Letter of Credit Sublimit. Within the foregoing limits, each Borrower may from time to time borrow, prepay pursuant to Section 2.10 and reborrow hereunder prior to the Commitment Termination Date for such Borrower.

SECTION 2.02 Procedures for Advances; Limitations on Borrowings.

(a) Any Borrower may request Advances hereunder by giving notice (a “Notice of Borrowing”) to the Administrative Agent (which shall promptly advise each Lender of its receipt thereof) not later than 10:00 A.M. (Chicago time) on the third Business Day prior to the date of any proposed borrowing of Eurodollar Rate Advances and on the date of any proposed borrowing of Base Rate Advances. Each Notice of Borrowing shall be sent by telecopier, confirmed immediately in writing, and shall be in substantially the form of Exhibit B, specifying therein the Borrower which is requesting Advances and the requested (i) date of borrowing (which shall be a Business Day), (ii) Type of Advances to be borrowed, (iii) the aggregate amount of such Advances, and (iv) in the case of a borrowing of Eurodollar Rate Advances, the initial Interest Period therefor. Each Lender shall, before 12:00 noon (Chicago time) on the date of such borrowing, make available for the account of its Applicable Lending Office to the Administrative Agent at its address referred to in Section 8.02, in same day funds, such Lender’s ratable portion of the requested borrowing. After the Administrative Agent’s receipt of such funds and upon fulfillment of the applicable conditions set forth in Article III, the Administrative Agent will make such funds available to the applicable Borrower at the Administrative Agent’s aforesaid address.

(b) Each Notice of Borrowing shall be irrevocable and binding on the applicable Borrower. If a Notice of Borrowing requests Eurodollar Rate Advances, the applicable Borrower shall indemnify each Lender against any loss, cost or expense incurred by such Lender as a result of any failure to fulfill on or before the requested borrowing date the applicable conditions set forth in Article III, including any loss, cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Lender to fund the requested Advance to be made by such Lender.

(c) Unless the Administrative Agent shall have received notice from a Lender prior to the date of any requested borrowing (or, in the case of a borrowing of Base Rate Advances to be made on the same Business Day as the Administrative Agent’s receipt of the relevant Notice of Borrowing, prior to 10:30 A.M., Chicago time, on such Business Day) that such Lender will not make available to the Administrative Agent such Lender’s ratable portion of such borrowing, the Administrative Agent may assume that such Lender has made such portion available to the Administrative Agent on the requested borrowing date in accordance with Section 2.02(a) and the Administrative Agent may, in reliance upon such assumption, make

available to the applicable Borrower on such date a corresponding amount. If and to the extent that such Lender shall not have so made such ratable portion available to the Administrative Agent, such Lender and such Borrower severally agree to repay to the Administrative Agent forthwith on demand such corresponding amount together with interest thereon, for each day from the date such amount is made available to such Borrower until the date such amount is repaid to the Administrative Agent, at (i) in the case of such Borrower, the interest rate applicable at the time to Advances made in connection with such borrowing and (ii) in the case of such Lender, the Federal Funds Rate. If such Lender shall repay to the Administrative Agent such corresponding amount, such amount so repaid shall constitute such Lender’s Advance as part of such Borrowing for purposes of this Agreement.

(d) The failure of any Lender to make the Advance to be made by it on any borrowing date shall not relieve any other Lender of its obligation, if any, hereunder to make its Advance on such date, but no Lender shall be responsible for the failure of any other Lender to make any Advance to be made by such other Lender.

(e) Each Borrowing of Base Rate Advances shall at all times be in an aggregate amount of $5,000,000 or a higher integral multiple of $1,000,000; and each Borrowing of Eurodollar Rate Advances shall at all times be in an aggregate amount of $10,000,000 or a higher integral multiple of $1,000,000. Notwithstanding anything to the contrary contained herein, the Borrowers collectively may not have more than 25 Borrowings of Eurodollar Rate Advances outstanding at any time.

SECTION 2.03 Facility and Utilization Fees.

(a) Each Borrower agrees to pay to the Administrative Agent, for the account of the Lenders according to their Pro Rata Shares, a facility fee for the period from the Closing Date to the Commitment Termination Date for such Borrower (or, if later, the date on which all Outstanding Credit Extensions to such Borrower have been paid in full) in an amount equal to the Facility Fee Rate for such Borrower multiplied by such Borrower’s Sublimit (or, after the Commitment Termination Date for such Borrower, the principal amount of all Outstanding Credit Extensions to such Borrower), payable on the last day of each March, June, September and December and on the Final Termination Date for such Borrower (and, if applicable, thereafter on demand).

(b) Utilization Fee. Each Borrower agrees to pay to the Administrative Agent, for the account of the Lenders according to their Pro Rata Shares, a utilization fee for each day on which either (i) the Outstanding Credit Extensions to all Borrowers exceed 33-1/3% of the aggregate amount of the Commitment Amounts or (ii) such Borrower’s Outstanding Credit Extensions exceed 33-1/3% of such Borrower’s Sublimit, in each case in an amount equal to the Utilization Fee Rate for such Borrower multiplied by such Borrower’s Outstanding Credit Extensions on such day, payable on the last day of each March, June, September and December and on the Commitment Termination Date for such Borrower.

SECTION 2.04 Reduction of Commitment Amounts; Adjustment of Sublimits. (a) Each Borrower shall have the right, upon at least two Business Days’ notice to the Administrative Agent, to ratably reduce the respective Commitment Amounts of the Lenders in accordance with

their Pro Rata Shares; provided that no Borrower may reduce the Commitment Amounts by an aggregate amount that is greater than the remainder of the amount of such Borrower’s Sublimit minus the Outstanding Credit Extensions to such Borrower; and provided, further, that each partial reduction of the Commitment Amounts shall be in the aggregate amount of $10,000,000 or an integral multiple thereof. Once reduced pursuant to this Section 2.04, the Commitment Amounts may not be increased.

(b) Any Borrower shall have the right at any time such Borrower’s Sublimit has been reduced to zero, upon at least two Business Days’ notice to the Administrative Agent, to terminate the Commitment of each Lender with respect to such Borrower in its entirety (but only if such Borrower concurrently pays all of its obligations hereunder). Upon any such termination, such Borrower shall cease to be a party hereto and shall no longer have any rights or obligations hereunder (except under provisions hereof which by their terms would survive any termination hereof).

(c) The Borrowers may from time to time so long as no Event of Default or Unmatured Event of Default exists with respect to any Borrower, upon not less than five Business Days’ notice to the Administrative Agent (which shall promptly notify each Lender), change their respective Sublimits; provided that (i) the sum of the Sublimits shall at all times be equal to the aggregate amount of the Commitment Amounts; and (ii) after giving effect to any adjustment of the Sublimits, (A) each Sublimit shall be an integral multiple of $50,000,000 (except that one Sublimit may not be such an integral multiple if the aggregate amount of the Commitment Amounts is not an integral multiple of $50,000,000); (B) no Borrower’s Sublimit shall exceed $500,000,000; (C) the Outstanding Credit Extensions to Exelon shall not exceed the Exelon Sublimit; (D) the Outstanding Credit Extensions to ComEd shall not exceed the ComEd Sublimit; (E) the Outstanding Credit Extensions to Genco shall not exceed the Genco Sublimit and (F) the Outstanding Credit Extensions to PECO shall not exceed the PECO Sublimit.

SECTION 2.05 Repayment of Advances. Each Borrower shall repay the principal amount of all Advances made to it on or before the Maturity Date for such Borrower.

SECTION 2.06 Interest on Advances. Each Borrower shall pay interest on the unpaid principal amount of each Advance made to it from the date of such Advance until such principal amount shall be paid in full, at the following rates per annum:

(a) At all times such Advance is a Base Rate Advance, a rate per annum equal to the Base Rate in effect from time to time, payable quarterly on the last day of each March, June, September and December and on the date such Base Rate Advance is converted to a Eurodollar Rate Advance or paid in full.

(b) Subject to Section 2.07, at all times such Advance is a Eurodollar Rate Advance, a rate per annum equal to the sum of the Eurodollar Rate for each applicable Interest Period plus the Applicable Margin in effect from time to time for such Borrower, payable on the last day of each Interest Period for such Eurodollar Rate Advance (and, if any Interest Period for such Advance is six months, on the day that is three months after the first day of such Interest Period) or, if earlier, on the date such Eurodollar Rate Advance is converted to a Base Rate Advance or paid in full.

SECTION 2.07 Additional Interest on Eurodollar Advances. Each Borrower shall pay to each Lender, so long as such Lender shall be required under regulations of the Board of Governors of the Federal Reserve System to maintain reserves with respect to liabilities or assets consisting of or including Eurocurrency Liabilities, additional interest on the unpaid principal amount of each Eurodollar Rate Advance of such Lender made to such Borrower, from the date of such Advance until such principal amount is paid in full or converted to a Base Rate Advance, at an interest rate per annum equal to the remainder obtained by subtracting (i) the Eurodollar Rate for each Interest Period for such Advance from (ii) the rate obtained by dividing such Eurodollar Rate by a percentage equal to 100% minus the Eurodollar Rate Reserve Percentage of such Lender for such Interest Period, payable on each date on which interest is payable on such Advance; provided that no Lender shall be entitled to demand such additional interest more than 90 days following the last day of the Interest Period in respect of which such demand is made; provided, further, that the foregoing proviso shall in no way limit the right of any Lender to demand or receive such additional interest to the extent that such additional interest relates to the retroactive application of the reserve requirements described above if such demand is made within 90 days after the implementation of such retroactive reserve requirements. Such additional interest shall be determined by the applicable Lender and notified to the applicable Borrower through the Administrative Agent, and such determination shall be conclusive and binding for all purposes, absent manifest error.

SECTION 2.08 Interest Rate Determination. (a) The Administrative Agent shall give prompt notice to the applicable Borrower and the Lenders of each applicable interest rate determined by the Administrative Agent for purposes of Section 2.06(a) or (b).

(b) If, with respect to any Eurodollar Rate Advances, the Majority Lenders notify the Administrative Agent that the Eurodollar Rate for any Interest Period for such Advances will not adequately reflect the cost to such Majority Lenders of making, funding or maintaining their respective Eurodollar Rate Advances for such Interest Period, the Administrative Agent shall forthwith so notify the applicable Borrower and the Lenders, whereupon

(i) each Eurodollar Rate Advance will automatically, on the last day of the then existing Interest Period therefor (unless prepaid or converted to a Base Rate Advance prior to such day), convert into a Base Rate Advance, and

(ii) the obligation of the Lenders to make, continue or convert into Eurodollar Rate Advances shall be suspended until the Administrative Agent shall notify the applicable Borrower and the Lenders that the circumstances causing such suspension no longer exist.

SECTION 2.09 Continuation and Conversion of Advances. (a) Any Borrower may on any Business Day, upon notice given to the Administrative Agent not later than 10:00 A.M. (Chicago time) on the third Business Day prior to the date of any proposed continuation of or conversion into Eurodollar Rate Advances, and on the date of any proposed conversion into Base Rate Advances, and subject to the provisions of Sections 2.08 and 2.12, continue Eurodollar Rate Advances for a new Interest Period or convert a Borrowing of Advances of one Type into Advances of the other Type; provided that any continuation of Eurodollar Rate Advances or conversion of Eurodollar Rate Advances into Base Rate Advances shall be made on, and only

on, the last day of an Interest Period for such Eurodollar Rate Advances, unless, in the case of such a conversion, such Borrower shall also reimburse the Lenders pursuant to Section 8.04(b) on the date of such conversion. Each such notice of a continuation or conversion shall, within the restrictions specified above, specify (i) the date of such continuation or conversion, (ii) the Advances to be continued or converted, and (iii) in the case of continuation of or conversion into Eurodollar Rate Advances, the duration of the Interest Period for such Advances.

(b) If a Borrower shall fail to select the Type of any Advance or the duration of any Interest Period for any Borrowing of Eurodollar Rate Advances in accordance with the provisions contained in the definition of “Interest Period” in Section 1.01 and Section 2.09(a), the Administrative Agent will forthwith so notify such Borrower and the Lenders and such Advances will automatically, on the last day of the then existing Interest Period therefor, convert into Base Rate Advances.

SECTION 2.10 Prepayments. Any Borrower may, upon notice to the Administrative Agent at least three Business Days prior to any prepayment of Eurodollar Rate Advances, or one Business Day’s notice prior to any prepayment of Base Rate Advances, in each case stating the proposed date and aggregate principal amount of the prepayment, and if such notice is given that Borrower shall, prepay the outstanding principal amounts of the Advances made as part of the same Borrowing in whole or ratably in part, together with accrued interest to the date of such prepayment on the principal amount prepaid; provided that (i) each partial prepayment shall be in an aggregate principal amount not less than $10,000,000 or a higher integral multiple of $1,000,000 in the case of any prepayment of Eurodollar Rate Advances and $5,000,000 or a higher integral multiple of $1,000,000 in the case of any prepayment of Base Rate Advances, and (ii) in the case of any such prepayment of a Eurodollar Rate Advance, such Borrower shall be obligated to reimburse the Lenders pursuant to Section 8.04(b) on the date of such prepayment.

SECTION 2.11 Increased Costs. (a) If on or after the date of this Agreement, any Lender or the LC Issuer determines that (i) the introduction of or any change (other than, in the case of Eurodollar Rate Advances, any change by way of imposition or increase of reserve requirements, included in the Eurodollar Rate Reserve Percentage) in or in the interpretation of any law or regulation or (ii) the compliance with any guideline or request from any central bank or other governmental authority (whether or not having the force of law) shall increase the cost to such Lender or the LC Issuer, as the case may be, of agreeing to make or making, funding or maintaining Eurodollar Rate Advances or of issuing or participating in any Facility LC, then the applicable Borrower shall from time to time, upon demand by such Lender (with a copy of such demand to the Administrative Agent) or the LC Issuer, as applicable, pay to the Administrative Agent for the account of such Lender additional amounts (without duplication of any amount payable pursuant to Section 2.14) sufficient to compensate such Lender or the LC Issuer, as applicable, for such increased cost; provided that no Lender shall be entitled to demand such compensation more than 90 days following the last day of the Interest Period in respect of which such demand is made and the LC Issuer shall not be entitled to demand such compensation more than 90 days following the expiration or termination (by a drawing or otherwise) of the Facility LC in respect of which such demand is made; provided, further, that the foregoing proviso shall in no way limit the right of any Lender or the LC Issuer to demand or receive such compensation to the extent that such compensation relates to the retroactive application of any law, regulation, guideline or request described in clause (i) or (ii) above if such demand is made within 90 days

after the implementation of such retroactive law, interpretation, guideline or request. A certificate as to the amount of such increased cost, submitted to the applicable Borrower and the Administrative Agent by a Lender or the LC Issuer, shall be conclusive and binding for all purposes, absent manifest error.

(b) If any Lender or the LC Issuer determines that, after the date of this Agreement, compliance with any law or regulation or any guideline or request from any central bank or other governmental authority (whether or not having the force of law) regarding capital adequacy requirements affects or would affect the amount of capital required or expected to be maintained by such Lender or the LC Issuer or any Person controlling such Lender or the LC Issuer (including, in any event, any determination after the date of this Agreement by any such governmental authority or central bank that, for purposes of capital adequacy requirements, any Lender’s Commitment to a Borrower or the LC Issuer’s commitment to issue Facility LCs for the account of such Borrower as the case may be does not constitute a commitment with an original maturity of less than one year) and that the amount of such capital is increased by or based upon the existence of such Lender’s Commitment to such Borrower or the LC Issuer’s commitment to issue Facility LCs for the account of such Borrower, as applicable, or the Advances made by such Lender to such Borrower or Reimbursement Obligations owed to the LC Issuer by such Borrower, as the case may be, then, upon demand by such Lender (with a copy of such demand to the Administrative Agent) or the LC Issuer, as applicable, such Borrower shall immediately pay to the Administrative Agent for the account of such Lender or LC Issuer, as applicable, from time to time as specified by such Lender or the LC Issuer, as applicable, additional amounts sufficient to compensate such Lender, the LC Issuer or such controlling Person, as applicable, in the light of such circumstances, to the extent that such Lender determines such increase in capital to be allocable to the existence of such Lender’s Commitment to such Borrower or the Advances made by such Lender to such Borrower or the LC Issuer determines such increase in capital to be allocable to the LC Issuer’s commitment to issue Facility LCs for the account of such Borrower or the Reimbursement Obligations owed by such Borrower to the LC Issuer; provided that no Lender or the LC Issuer shall be entitled to demand such compensation more than one year following the payment to or for the account of such Lender of all other amounts payable hereunder by such Borrower and under any Note of such Borrower held by such Lender and the termination of such Lender’s Commitment to such Borrower and the LC Issuer shall not be entitled to demand such compensation more than one year after the expiration or termination (by drawing or otherwise) of all Facility LCs issued for the account of such Borrower and the termination of the LC Issuer’s commitment to issue Facility LCs for the account of such Borrower; provided, further, that the foregoing provision shall in no way limit the right of any Lender or the LC Issuer to demand or receive such compensation to the extent that such compensation relates to the retroactive application of any law, regulation, guideline or request described above if such demand is made within one year after the implementation of such retroactive law, interpretation, guideline or request. A certificate as to such amounts submitted to the applicable Borrower and the Administrative Agent by the applicable Lender or the LC Issuer shall be conclusive and binding, for all purposes, absent manifest error.

(c) Any Lender claiming compensation pursuant to this Section 2.11 shall use its best efforts (consistent with its internal policy and legal and regulatory restrictions) to change the jurisdiction of its Applicable Lending Office if the making of such a change would avoid the

need for, or reduce the amount of, any such compensation that may thereafter accrue and would not, in the reasonable judgment of such Lender, be otherwise disadvantageous to such Lender.

SECTION 2.12 Illegality. Notwithstanding any other provision of this Agreement, if any Lender shall notify the Administrative Agent that the introduction of or any change in or in the interpretation of any law or regulation makes it unlawful, or any central bank or other governmental authority asserts that it is unlawful, for such Lender or its Eurodollar Lending Office to perform its obligations hereunder to make Eurodollar Rate Advances or to fund or maintain Eurodollar Rate Advances hereunder, (i) the obligation of such Lender to make, continue or convert Advances into Eurodollar Rate Advances shall be suspended (subject to the following paragraph of this Section 2.12) until the Administrative Agent shall notify the applicable Borrower and the Lenders that the circumstances causing such suspension no longer exist and (ii) all Eurodollar Rate Advances of such Lender then outstanding shall, on the last day of the then applicable Interest Period (or such earlier date as such Lender shall designate upon not less than five Business Days’ prior written notice to the Administrative Agent), be automatically converted into Base Rate Advances.

If the obligation of any Lender to make, continue or convert into Eurodollar Rate Advances has been suspended pursuant to the preceding paragraph, then, unless and until the Administrative Agent shall notify the applicable Borrower and the Lenders that the circumstances causing such suspension no longer exist, (i) all Advances that would otherwise be made by such Lender as Eurodollar Rate Advances shall instead be made as Base Rate Advances and (ii) to the extent that Eurodollar Rate Advances of such Lender have been converted into Base Rate Advances pursuant to the preceding paragraph or made instead as Base Rate Advances pursuant to the preceding clause (i), all payments and prepayments of principal that would have otherwise been applied to such Eurodollar Rate Advances of such Lender shall be applied instead to such Base Rate Advances of such Lender.

SECTION 2.13 Payments and Computations. (a) Each Borrower shall make each payment hereunder and under any Note issued by such Borrower not later than 10:00 A.M. (Chicago time) on the day when due in U.S. dollars to the Administrative Agent at its address referred to in Section 8.02 in same day funds without setoff, counterclaim or other deduction. The Administrative Agent will promptly thereafter cause to be distributed like funds relating to the payment of principal, interest, facility fees, utilization fees and letter of credit fees ratably (other than amounts payable pursuant to Section 2.02(b), 2.07, 2.11, 2.14 or 8.04(b)) to the Lenders for the account of their respective Applicable Lending Offices, and like funds relating to the payment of any other amount payable to any Lender to such Lender for the account of its Applicable Lending Office, in each case to be applied in accordance with the terms of this Agreement. Upon its acceptance of an Assignment and Acceptance and recording of the information contained therein in the Register pursuant to Section 8.07(d), from and after the effective date specified in such Assignment and Acceptance, the Administrative Agent shall make all payments hereunder in respect of the interest assigned thereby to the Lender assignee thereunder, and the parties to such Assignment and Acceptance shall make all appropriate adjustments in such payments for periods prior to such effective date directly between themselves.

(b) Each Borrower hereby authorizes each Lender, if and to the extent any payment owed to such Lender by such Borrower is not made when due hereunder, to charge from time to time against any or all of such Borrower’s accounts with such Lender any amount so due.

(c) All computations of interest based on the Prime Rate shall be made by the Administrative Agent on the basis of a year of 365 or 366 days, as the case may be, and all computations of interest based on the Eurodollar Rate or the Federal Funds Rate and of fees shall be made by the Administrative Agent, and all computations of interest pursuant to Section 2.07 shall be made by a Lender, on the basis of a year of 360 days, in each case for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest or fees are payable. Each determination by the Administrative Agent (or, in the case of Section 2.07, by a Lender) of an interest rate hereunder shall be conclusive and binding for all purposes, absent manifest error.

(d) Whenever any payment hereunder shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of any interest or fees, as the case may be; provided that if such extension would cause payment of interest on or principal of a Eurodollar Rate Advance to be made in the next following calendar month, such payment shall be made on the next preceding Business Day.

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

(f) Notwithstanding anything to the contrary contained herein, any amount payable by a Borrower hereunder that is not paid when due (whether at stated maturity, by acceleration or otherwise) shall (to the fullest extent permitted by law) bear interest from the date when due until paid in full at a rate per annum equal at all times to the Base Rate plus 2%, payable upon demand.

SECTION 2.14 Taxes. (a) Any and all payments by any Borrower hereunder or under any Note issued by such Borrower shall be made, in accordance with Section 2.13, free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, excluding, in the case of each Lender, the LC Issuer and the Administrative Agent, taxes imposed on its income, and franchise taxes imposed on it, by the jurisdiction under the laws of which such Lender, the LC Issuer or the Administrative Agent (as the case may be) is organized or any political subdivision thereof and,

in the case of each Lender, taxes imposed on its income, and franchise taxes imposed on it, by the jurisdiction of such Lender’s Applicable Lending Office or any political subdivision thereof (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities being hereinafter referred to as “Taxes”). If a Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder or under any Note issued by such Borrower to any Lender, the LC Issuer or the Administrative Agent, (i) the sum payable shall be increased as may be necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 2.14) such Lender, the LC Issuer or the Administrative Agent (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) such Borrower shall make such deductions and (iii) such Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable law.

(b) In addition, each Borrower severally agrees to pay any present or future stamp or documentary taxes or any other excise or property taxes, charges or similar levies to the extent arising from the execution, delivery or registration of this Agreement or any Note (hereinafter referred to as “Other Taxes”), in each case to the extent attributable to such Borrower; it being understood that to the extent any Other Taxes so payable are not attributable to any particular Borrower, each Borrower shall pay its proportionate share thereof according to the amounts of the Borrowers’ respective Sublimits at the time such Other Taxes arose.

(c) No Lender may claim or demand payment or reimbursement in respect of any Taxes or Other Taxes pursuant to this Section 2.14 if such Taxes or Other Taxes, as the case may be, were imposed solely as the result of a voluntary change in the location of the jurisdiction of such Lender’s Applicable Lending Office.

(d) Each Borrower will indemnify each Lender, the LC Issuer and the Administrative Agent for the full amount of Taxes or Other Taxes (including any Taxes or Other Taxes imposed by any jurisdiction on amounts payable under this Section 2.14) paid by such Lender, the LC Issuer or the Administrative Agent (as the case may be) and any liability (including penalties, interest and expenses) arising therefrom or with respect thereto, whether or not such Taxes or Other Taxes were correctly or legally asserted, in each case to the extent attributable to such Borrower; it being understood that to the extent any Taxes, Other Taxes or other liabilities described above are not attributable to a particular Borrower, each Borrower shall pay its proportionate share thereof according to the amounts of the Borrowers’ respective Sublimits at the time such Taxes, Other Taxes or other liability arose. This indemnification shall be made within 30 days from the date such Lender, the LC Issuer or the Administrative Agent (as the case may be) makes written demand therefor.

(e) Prior to the date of an initial borrowing hereunder in the case of each Lender listed on the signature pages hereof, and on the date of the Assignment and Acceptance pursuant to which it became a Lender in the case of each other Lender, and from time to time thereafter within 30 days from the date of request if requested by any Borrower or the Administrative Agent, each Lender organized under the laws of a jurisdiction outside the United States shall provide the Administrative Agent and each Borrower with the forms prescribed by the Internal Revenue Service of the United States certifying that such Lender is exempt from United States withholding taxes with respect to all payments to be made to such Lender hereunder and under

any Note. If for any reason during the term of this Agreement, any Lender becomes unable to submit the forms referred to above or the information or representations contained therein are no longer accurate in any material respect, such Lender shall notify the Administrative Agent and the Borrowers in writing to that effect. Unless the Borrowers and the Administrative Agent have received forms or other documents satisfactory to them indicating that payments hereunder or under any Note are not subject to United States withholding tax, the Borrowers or the Administrative Agent shall withhold taxes from such payments at the applicable statutory rate in the case of payments to or for any Lender organized under the laws of a jurisdiction outside the United States and no Lender may claim or demand payment or reimbursement for such withheld taxes pursuant to this Section 2.14.

(f) Any Lender claiming any additional amounts payable pursuant to this Section 2.14 shall use its best efforts (consistent with its internal policy and legal and regulatory restrictions) to change the jurisdiction of its Applicable Lending Office if the making of such a change would avoid the need for, or reduce the amount of, any such additional amounts which may thereafter accrue and would not, in the reasonable judgment of such Lender, be otherwise disadvantageous to such Lender.

(g) If a Borrower makes any additional payment to any Lender pursuant to this Section 2.14 in respect of any Taxes or Other Taxes, and such Lender determines that it has received (i) a refund of such Taxes or Other Taxes or (ii) a credit against or relief or remission for, or a reduction in the amount of, any tax or other governmental charge attributable solely to any deduction or credit for any Taxes or Other Taxes with respect to which it has received payments under this Section 2.14, such Lender shall, to the extent that it can do so without prejudice to the retention of such refund, credit, relief, remission or reduction, pay to such Borrower such amount as such Lender shall have determined to be attributable to the deduction or withholding of such Taxes or Other Taxes. If, within one year after the payment of any such amount to such Borrower, such Lender determines that it was not entitled to such refund, credit, relief, remission or reduction to the full extent of any payment made pursuant to the first sentence of this Section 2.14(g), such Borrower shall upon notice and demand of such Lender promptly repay the amount of such overpayment. Any determination made by a Lender pursuant to this Section 2.14(g) shall in the absence of bad faith or manifest error be conclusive, and nothing in this Section 2.14(g) shall be construed as requiring any Lender to conduct its business or to arrange or alter in any respect its tax or financial affairs (except as required by Section 2.14(f)) so that it is entitled to receive such a refund, credit or reduction or as allowing any Person to inspect any records, including tax returns, of such Lender.

(h) Without prejudice to the survival of any other agreement of any Borrower or any Lender hereunder, the agreements and obligations of the Borrowers and the Lenders contained in this Section 2.14 shall survive the payment in full of principal and interest hereunder and the termination of this Agreement; provided that no Lender shall be entitled to demand any payment from a Borrower under this Section 2.14 more than one year following the payment to or for the account of such Lender of all other amounts payable by such Borrower hereunder and under any Note issued by such Borrower to such Lender and the termination of such Lender’s Commitment to such Borrower; provided, further, that the foregoing proviso shall in no way limit the right of any Lender to demand or receive any payment under this Section 2.14 to the extent that such payment relates to the retroactive application of any Taxes or Other

Taxes if such demand is made within one year after the implementation of such Taxes or Other Taxes.

SECTION 2.15 Sharing of Payments, Etc. If any Lender shall obtain any payment (whether voluntary, involuntary, through the exercise of any right of set-off, or otherwise) on account of the Advances made by it to any Borrower or its participation interest in any Facility LC issued for the account of any Borrower (other than pursuant to Section 2.02(b), 2.07, 2.11, 2.14 or 8.04(b)) in excess of its ratable share of payments on account of the Advances to such Borrower and Facility LCs issued for the account of such Borrower obtained by all Lenders, such Lender shall forthwith purchase from the other Lenders such participations in the Advances made by them to such Borrower and/or LC Obligations of such Borrower as shall be necessary to cause such purchasing Lender to share the excess payment ratably with each of them, provided that if all or any portion of such excess payment is thereafter recovered from such purchasing Lender, such purchase from each Lender shall be rescinded and such Lender shall repay to the purchasing Lender the purchase price to the extent of such recovery together with an amount equal to such Lender’s ratable share (according to the proportion of (i) the amount of such Lender’s required repayment to (ii) the total amount so recovered from the purchasing Lender) of any interest or other amount paid or payable by the purchasing Lender in respect of the total amount so recovered. The Borrowers agree that any Lender so purchasing a participation from another Lender pursuant to this Section 2.15 may, to the fullest extent permitted by law, exercise all its rights of payment (including the right of set-off) with respect to such participation as fully as if such Lender were the direct creditor of the applicable Borrower in the amount of such participation.

SECTION 2.16 Facility LCs.

SECTION 2.16.1 Issuance. The LC Issuer hereby agrees, on the terms and conditions set forth in this Agreement (including the limitations set forth in Section 2.01), upon the request of any Borrower, to issue standby letters of credit and to renew, extend, increase or otherwise modify Facility LCs (“Modify,” and each such action a “Modification”) for such Borrower, from time to time from and including the date of this Agreement and prior to the Commitment Termination Date for such Borrower. No Facility LC shall have an expiry date later than the earlier of (a) one year after the date of issuance, or of extension or renewal, thereof or (b) the scheduled Commitment Termination Date. By their execution of this Agreement, the parties hereto agree that on the Closing Date (without any further action by any Person), each Existing Letter of Credit shall be deemed to have been issued under this Agreement and the rights and obligations of the issuer and the account party thereunder shall be subject to the terms hereof.

SECTION 2.16.2 Participations. Upon the issuance or Modification by the LC Issuer of a Facility LC in accordance with this Section 2.16 (or, in this case of the Existing Letters of Credit, on the Closing Date), the LC Issuer shall be deemed, without further action by any party hereto, to have unconditionally and irrevocably sold to each Lender, and each Lender shall be deemed, without further action by any party hereto, to have unconditionally and irrevocably purchased from the LC Issuer, a participation in

such Facility LC (and each Modification thereof) and the related LC Obligations in proportion to its Pro Rata Share.

SECTION 2.16.3 Notice. Subject to Section 2.16.1, the applicable Borrower shall give the LC Issuer notice prior to 10:00 A.M. (Chicago time) at least five Business Days prior to the proposed date of issuance or Modification of each Facility LC, specifying the beneficiary, the proposed date of issuance (or Modification) and the expiry date of such Facility LC, and describing the proposed terms of such Facility LC and the nature of the transactions proposed to be supported thereby. Upon receipt of such notice, the LC Issuer shall promptly notify the Administrative Agent, and the Administrative Agent shall promptly notify each Lender, of the contents thereof and of the amount of such Lender’s participation in such proposed Facility LC. The issuance or Modification by the LC Issuer of any Facility LC shall, in addition to the applicable conditions precedent set forth in Article III (the satisfaction of which the LC Issuer shall have no duty to ascertain), be subject to the conditions precedent that such Facility LC shall be satisfactory to the LC Issuer and that the applicable Borrower shall have executed and delivered such application agreement and/or such other instruments and agreements relating to such Facility LC as the LC Issuer shall have reasonably requested (each a “Facility LC Application”). In the event of any conflict between the terms of this Agreement and the terms of any Facility LC Application, the terms of this Agreement shall control.

SECTION 2.16.4 LC Fees. Each Borrower shall pay to the Agent, for the account of the Lenders ratably in accordance with their respective Pro Rata Shares, with respect to each Facility LC issued for the account of such Borrower, a letter of credit fee at a per annum rate equal to the LC Fee Rate to such Borrower in effect from time to time on the average daily undrawn stated amount under such Facility LC, such fee to be payable in arrears on the last day of each March, June, September and December and on the Maturity Date for such Borrower (and thereafter on demand). Each Borrower shall also pay to the LC Issuer for its own account (x) a fronting fee in an amount and at the times agreed upon between the LC Issuer and such Borrower and (y) documentary and processing charges in connection with the issuance or Modification of and draws under Facility LCs in accordance with the LC Issuer’s standard schedule for such charges as in effect from time to time.

SECTION 2.16.5 Administration; Reimbursement by Lenders. Upon receipt from the beneficiary of any Facility LC of any demand for payment under such Facility LC, the LC Issuer shall notify the Administrative Agent and the Administrative Agent shall promptly notify the applicable Borrower and each Lender as to the amount to be paid by the LC Issuer as a result of such demand and the proposed payment date (the “LC Payment Date”). The responsibility of the LC Issuer to the applicable Borrower and each Lender shall be only to determine that the documents (including each demand for payment) delivered under each Facility LC in connection with such presentment shall be in conformity in all material respects with such Facility LC. The LC Issuer shall endeavor to exercise the same care in the issuance and administration of the Facility LCs as it does with respect to letters of credit in which no participations are granted, it being understood that in the absence of any gross negligence or willful misconduct by the LC

Issuer, each Lender shall be unconditionally and irrevocably liable, without regard to the occurrence of the Commitment Termination Date, the occurrence of any Event of Default or Unmatured Event of Default or any condition precedent whatsoever, to reimburse the LC Issuer on demand for (i) such Lender’s Pro Rata Share of the amount of each payment made by the LC Issuer under each Facility LC to the extent such amount is not reimbursed by the applicable Borrower pursuant to Section 2.16.6, plus (ii) interest on the foregoing amount to be reimbursed by such Lender, for each day from the date of the LC Issuer’s demand for such reimbursement (or, if such demand is made after 11:00 A.M. (Chicago time) on such day, from the next succeeding Business Day) to the date on which such Lender pays the amount to be reimbursed by it, at a rate of interest per annum equal to the Federal Funds Rate for the first three days and, thereafter, at the Base Rate.

SECTION 2.16.6 Reimbursement by Borrowers. Each Borrower shall be irrevocably and unconditionally obligated to reimburse the LC Issuer on or before the applicable LC Payment Date for any amount to be paid by the LC Issuer upon any drawing under any Facility LC issued for the account of such Borrower, without presentment, demand, protest or other formalities of any kind; provided that neither the applicable Borrower nor any Lender shall hereby be precluded from asserting any claim for direct (but not consequential) damages suffered by such Borrower or such Lender to the extent, but only to the extent, caused by (i) the willful misconduct or gross negligence of the LC Issuer in determining whether a request presented under any Facility LC complied with the terms of such Facility LC or (ii) the LC Issuer’s failure to pay under any Facility LC after the presentation to it of a request strictly complying with the terms and conditions of such Facility LC. All such amounts paid by the LC Issuer and remaining unpaid by the applicable Borrower shall bear interest, payable on demand, for each day until paid at a rate per annum equal to the Base Rate plus 2%. The LC Issuer will pay to each Lender ratably in accordance with its Pro Rata Share all amounts received by it from any Borrower for application in payment, in whole or in part, of the Reimbursement Obligation in respect of any Facility LC issued by the LC Issuer, but only to the extent such Lender has made payment to the LC Issuer in respect of such Facility LC pursuant to Section 2.16.5. So long as the Commitment Termination Date has not occurred with respect to a Borrower, but subject to the terms and conditions of this Agreement (including the submission of a Notice of Borrowing in compliance with Section 2.02 and the satisfaction of the applicable conditions precedent set forth in Article III), such Borrower may request Advances hereunder for the purpose of satisfying any Reimbursement Obligation.

SECTION 2.16.7 Obligations Absolute. Each Borrower’s obligations under this Section 2.16 shall be absolute and unconditional under any and all circumstances and irrespective of any setoff, counterclaim or defense to payment which such Borrower may have against the LC Issuer, any Lender or any beneficiary of a Facility LC. Each Borrower agrees with the LC Issuer and the Lenders that the LC Issuer and the Lenders shall not be responsible for, and such Borrower’s Reimbursement Obligation in respect of any Facility LC issued for its account shall not be affected by, among other things, the validity or genuineness of documents or of any endorsements thereon, even if such documents should in fact prove to be in any or all respects invalid, fraudulent or forged, or any dispute between or among such Borrower, any of its Affiliates, the beneficiary of

any Facility LC or any financing institution or other party to whom any Facility LC may be transferred or any claims or defenses whatsoever of such Borrower or of any of its Affiliates against the beneficiary of any Facility LC or any such transferee. The LC Issuer shall not be liable for any error, omission, interruption or delay in transmission, dispatch or delivery of any message or advice, however transmitted, in connection with any Facility LC. Each Borrower agrees that any action taken or omitted by the LC Issuer or any Lender under or in connection with any Facility LC issued for the account of such Borrower and the related drafts and documents, if done without gross negligence or willful misconduct, shall be binding upon such Borrower and shall not put the LC Issuer or any Lender under any liability to such Borrower. Nothing in this Section 2.16.7 is intended to limit the right of any Borrower to make a claim against the LC Issuer for damages as contemplated by the proviso to the first sentence of Section 2.16.6.

SECTION 2.16.8 Actions of LC Issuer. The LC Issuer shall be entitled to rely, and shall be fully protected in relying, upon any Facility LC, draft, writing, resolution, notice, consent, certificate, affidavit, letter, cablegram, telegram, telecopy, telex or teletype message, statement, order or other document believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons, and upon advice and statements of legal counsel, independent accountants and other experts selected by the LC Issuer. The LC Issuer shall be fully justified in failing or refusing to take any action under this Agreement unless it shall first have received such advice or concurrence of the Majority Lenders as it reasonably deems appropriate or it shall first be indemnified to its reasonable satisfaction by the Lenders against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action. Notwithstanding any other provision of this Section 2.16, the LC Issuer shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement in accordance with a request of the Majority Lenders, and such request and any action taken or failure to act pursuant thereto shall be binding upon the Lenders and any future holder of a participation in any Facility LC.

SECTION 2.16.9 Indemnification. Each Borrower hereby agrees to indemnify and hold harmless each Lender, the LC Issuer and the Agent, and their respective directors, officers, agents and employees, from and against any and all claims and damages, losses, liabilities, costs or expenses which such Lender, the LC Issuer or the Agent may incur (or which may be claimed against such Lender, the LC Issuer or the Agent by any Person whatsoever) by reason of or in connection with the issuance, execution and delivery or transfer of or payment or failure to pay under any Facility LC issued for the account of such Borrower or any actual or proposed use of any such Facility LC, including any claims, damages, losses, liabilities, costs or expenses which the LC Issuer may incur by reason of or in connection with (i) the failure of any other Lender to fulfill or comply with its obligations to the LC Issuer hereunder (but nothing herein contained shall affect any right such Borrower may have against any defaulting Lender) or (ii) by reason of or on account of the LC Issuer issuing any such Facility LC which specifies that the term “Beneficiary” included therein includes any successor by operation of law of the named Beneficiary, but which Facility LC does not require that any drawing by any such successor Beneficiary be accompanied by a copy of a legal document, satisfactory to the LC Issuer, evidencing the appointment of such successor

Beneficiary; provided that no Borrower shall be required to indemnify any Lender, the LC Issuer or the Agent for any claims, damages, losses, liabilities, costs or expenses to the extent, but only to the extent, caused by (x) the willful misconduct or gross negligence of the LC Issuer in determining whether a request presented under any Facility LC complied with the terms of such Facility LC or (y) the LC Issuer’s failure to pay under any Facility LC after the presentation to it of a request strictly complying with the terms and conditions of such Facility LC. Nothing in this Section 2.16.9 is intended to limit the obligations of any Borrower under any other provision of this Agreement.

SECTION 2.16.10 Lenders’ Indemnification. Each Lender shall, ratably in accordance with its Pro Rata Share, indemnify the LC Issuer, its affiliates and their respective directors, officers, agents and employees (to the extent not reimbursed by the Borrower) against any cost, expense (including reasonable counsel fees and disbursements), claim, demand, action, loss or liability (except such as result from such indemnitees’ gross negligence or willful misconduct or the LC Issuer’s failure to pay under any Facility LC after the presentation to it of a request strictly complying with the terms and conditions of the Facility LC) that such indemnitees may suffer or incur in connection with this Section 2.16 or any action taken or omitted by such indemnitees hereunder.

SECTION 2.16.11 Rights as a Lender. In its capacity as a Lender, the LC Issuer shall have the same rights and obligations as any other Lender.

As to any matters not expressly provided for by this Agreement (including enforcement or collection of the Notes), the Administrative Agent shall not be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of the Majority Lenders, and such instructions shall be binding upon all Lenders and all holders of Notes; provided that the Administrative Agent shall not be required to take any action which exposes the Administrative Agent to personal liability or which is contrary to this Agreement or applicable law.

Neither the Administrative Agent nor any of its directors, officers, agents or employees shall be liable for any action taken or omitted to be taken by it or them under or in connection with this Agreement, except for its or their respective own gross negligence or willful misconduct. Without limiting the generality of the foregoing: (i) the Administrative Agent may treat the payee of any Note as the holder thereof until the Administrative Agent receives and accepts an Assignment and Acceptance entered into by the Lender which is the payee of such Note, as assignor, and an Eligible Assignee, as assignee, as provided in Section 8.07; (ii) the Administrative Agent may consult with legal counsel (including counsel for a Borrower), independent public accountants and other experts selected by it and shall not be liable for any action taken or omitted to be taken in good faith by it in accordance with the advice of such counsel, accountants or experts; (iii) the Administrative Agent makes no warranty or representation to any Lender and shall not be responsible to any Lender for any statements, warranties or representations (whether written or oral) made in or in connection with this Agreement; (iv) the Administrative Agent shall not have any duty to ascertain or to inquire as to the performance or observance of any of the terms, covenants or conditions of this Agreement on the part of any Borrower or to inspect the property (including the books and records) of any Borrower; (v) the Administrative Agent shall not be responsible to any Lender

for the due execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement or any other instrument or document furnished pursuant hereto; and (vi) the Administrative Agent shall not incur any liability under or in respect of this Agreement by acting upon any notice, consent, certificate or other instrument or writing (which may be by telecopier, telegram, cable or telex) believed by it to be genuine and signed or sent by the proper party or parties.

SECTION 7.03 Agents and Affiliates. With respect to its Commitment, Advances and Notes, Bank One shall have the same rights and powers under this Agreement as any other Lender and may exercise the same as though it were not an Agent; and the term “Lender” or “Lenders” shall, unless otherwise expressly indicated, include Bank One in its individual capacity. Bank One and its affiliates may accept deposits from, lend money to, act as trustee under indentures of, and generally engage in any kind of business with, any Borrower, any subsidiary of any Borrower and any Person who may do business with or own securities of any Borrower or any such subsidiary, all as if it were not an Agent and without any duty to account therefor to the Lenders.

SECTION 7.04 Lender Credit Decision. Each Lender acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender and based on the financial statements referred to in Section 4.01(e) and such other documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement.

SECTION 7.05 Indemnification. The Lenders agree to indemnify each Agent (to the extent not reimbursed by a Borrower), ratably according to their respective Pro Rata Shares, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may be imposed on, incurred by, or asserted against any such Agent in any way relating to or arising out of this Agreement or any action taken or omitted by any such Agent under this Agreement, provided that no Lender shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from such Agent’s gross negligence or willful misconduct. Without limiting the foregoing, each Lender agrees to reimburse each such Agent promptly upon demand for its Pro Rata Share of any out-of-pocket expenses (including reasonable counsel fees) incurred by such Agent in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement, to the extent that such expenses are reimbursable by a Borrower but for which such Agent is not reimbursed by such Borrower.

SECTION 7.06 Successor Administrative Agent. The Administrative Agent may resign at any time by giving written notice thereof to the Lenders and the Borrowers and may be removed at any time with or without cause by the Majority Lenders. Upon any such resignation or removal, the Majority Lenders shall have the right to appoint a successor Administrative Agent. If no successor Administrative Agent shall have been so appointed by the Majority

Lenders, and shall have accepted such appointment, within 30 days after the retiring Administrative Agent’s giving of notice of resignation or the Majority Lenders’ removal of the retiring Administrative Agent, then the retiring Administrative Agent may, on behalf of the Lenders, appoint a successor Administrative Agent, which shall be a commercial bank described in clause (i) or (ii) of the definition of “Eligible Assignee” and having a combined capital and surplus of at least $150,000,000. Upon the acceptance of any appointment as Administrative Agent hereunder by a successor Administrative Agent, such successor Administrative Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations under this Agreement. After any retiring Administrative Agent’s resignation or removal hereunder as Administrative Agent, the provisions of this Article VII shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent under this Agreement. Notwithstanding the foregoing, if no Event of Default or Unmatured Event of Default shall have occurred and be continuing, then no successor Administrative Agent shall be appointed under this Section 7.06 without the prior written consent of the Borrowers, which consent shall not be unreasonably withheld or delayed.

SECTION 7.07 Co-Documentation Agents, Syndication Agent and Co-Lead Arranger. The titles “Co-Documentation Agent,” “Syndication Agent” and “Co-Lead Arranger” are purely honorific, and no Person designated as a “Co-Documentation Agent,” the “Syndication Agent” or a “Co-Lead Arranger” shall have any duties or responsibilities in such capacity.

Each Borrower further severally agrees to pay on demand all costs and expenses, if any (including counsel fees and expenses of outside counsel and of internal counsel), incurred by the Agent, the LC Issuer or any Lender in connection with the collection and enforcement (whether through negotiations, legal proceedings or otherwise) of such Borrower’s obligations this Agreement, any Note issued by such Borrower and the other documents to be delivered by such Borrower hereunder, including reasonable counsel fees and expenses in connection with the enforcement of rights under this Section 8.04(a), in each case to the extent attributable to such Borrower; it being understood that to the extent any such costs and expenses are not attributable to a particular Borrower, each Borrower shall pay its proportionate share thereof according to the Borrowers’ respective Sublimits at the time such costs and expenses were incurred.

(b) If any payment of principal of, or any conversion of, any Eurodollar Rate Advance is made other than on the last day of the Interest Period for such Advance, as a result of a payment or conversion pursuant to Section 2.09 or 2.12 or acceleration of the maturity of the

Advances pursuant to Section 6.01 or for any other reason, the applicable Borrower shall, upon demand by any Lender (with a copy of such demand to the Administrative Agent), pay to the Administrative Agent for the account of such Lender any amount required to compensate such Lender for any additional losses, costs or expenses which it may reasonably incur as a result of such payment or conversion, including any loss, cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by any Lender to fund or maintain such Advance.

(c) Each Borrower hereby severally agrees to indemnify and hold each Lender, the LC Issuer, each Agent and each of their respective Affiliates, officers, directors and employees (each, an “Indemnified Person”) harmless from and against any and all claims, damages, losses, liabilities, costs or expenses (including reasonable attorney’s fees and expenses, whether or not such Indemnified Person is named as a party to any proceeding or is otherwise subjected to judicial or legal process arising from any such proceeding) that any of them may pay or incur arising out of or relating to this Agreement, any Note issued by such Borrower or the transactions contemplated hereby, or the use by such Borrowers or any of its Subsidiaries of the proceeds of any Advance to such Borrower, in each case to the extent such claims damages, losses, liabilities, costs or expenses are attributable to such Borrower, it being understood that to the extent any such claims, damages, losses, liabilities, costs or expenses are not attributable to a particular Borrower, each Borrower shall pay its proportionate share thereof according to the Borrowers’ respective Sublimits at the time such claims, damages, losses, liabilities, costs or expenses arose; provided that no Borrower shall be liable for any portion of such claims, damages, losses, liabilities, costs or expenses resulting from such Indemnified Person’s gross negligence or willful misconduct. Each Borrower’s obligations under this Section 8.04(c) shall survive the repayment of all amounts owing by such Borrower to the Lenders and the Administrative Agent under this Agreement and any Note issued by such Borrower and the termination of the Commitments to such Borrower. If and to the extent that the obligations of a Borrower under this Section 8.04(c) are unenforceable for any reason, such Borrower agrees to make the maximum contribution to the payment and satisfaction thereof which is permissible under applicable law.

SECTION 8.05 Right of Set-off. Upon (i) the occurrence and during the continuance of any Event of Default with respect to a Borrower and (ii) the making of the request or the granting of the consent specified by Section 6.01 to authorize the Administrative Agent to declare the Advances to such Borrower due and payable pursuant to the provisions of Section 6.01, each Lender is hereby authorized at any time and from time to time, 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 and other indebtedness at any time owing by such Lender to or for the credit or the account of such Borrower against any and all of the obligations of such Borrower now or hereafter existing under this Agreement and any Note of such Borrower held by such Lender, whether or not such Lender shall have made any demand under this Agreement or such Note and although such obligations may be unmatured. Each Lender agrees promptly to notify the applicable Borrower after any such set-off and application made by such Lender, provided that the failure to give such notice shall not affect the validity of such set-off and application. The rights of each Lender under this Section 8.05 are in addition to other rights and remedies (including other rights of set-off) that such Lender may have.

SECTION 8.06 Binding Effect. This Agreement shall become effective when counterparts hereof shall have been executed by the Borrowers and the Agents and when the Administrative Agent shall have been notified by each Lender that such Lender has executed a counterpart hereof and thereafter shall be binding upon and inure to the benefit of the Borrowers, the Agents and each Lender and their respective successors and assigns, provided that (except as permitted by Section 5.02(b)(iii)) no Borrower shall have the right to assign rights hereunder or any interest herein without the prior written consent of all Lenders.

SECTION 8.07 Assignments and Participations. (a) Each Lender may, with the prior written consent of Exelon, the LC Issuer and the Administrative Agent (which consents shall not be unreasonably withheld or delayed), and if demanded by a Borrower pursuant to Section 8.07(g) shall to the extent required by such Section, assign to one or more banks or other entities all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment, the Advances owing to it, its participation in Facility LCs and any Note or Notes held by it); provided that (i) each such assignment shall be of a constant, and not a varying, percentage of all of the assigning Lender’s rights and obligations under this Agreement, (ii) the Commitment Amount of the assigning Lender being assigned pursuant to each such assignment (determined as of the date of the Assignment and Acceptance with respect to such assignment) shall in no event be less than $5,000,000 or, if less, the entire amount of such Lender’s Commitment, and shall be an integral multiple of $1,000,000 or such Lender’s entire Commitment, (iii) each such assignment shall be to an Eligible Assignee, (iv) the parties to each such assignment shall execute and deliver to the Administrative Agent, for its acceptance and recording in the Register, an Assignment and Acceptance, together with any Note or Notes subject to such assignment and a processing and recordation fee of $3,500 (which shall be payable by one or more of the parties to the Assignment and Acceptance, and not by any Borrower, and shall not be payable if the assignee is a Federal Reserve Bank), and (v) the consent of Exelon shall not be required after the occurrence and during the continuance of any Event of Default. Upon such execution, delivery, acceptance and recording, from and after the effective date specified in each Assignment and Acceptance, (x) the assignee thereunder shall be a party hereto and, to the extent that rights and obligations hereunder have been assigned to it pursuant to such Assignment and Acceptance, have the rights and obligations of a Lender hereunder and (y) the Lender assignor thereunder shall, to the extent that rights and obligations hereunder have been assigned by it pursuant to such Assignment and Acceptance, relinquish its rights and be released from its obligations under this Agreement and, in the case of an Assignment and Acceptance covering all or the remaining portion of an assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto (although an assigning Lender shall continue to be entitled to indemnification pursuant to Section 8.04(c)). Notwithstanding anything contained in this Section 8.07(a) to the contrary, (A) the consent of Exelon, the LC Issuer and the Administrative Agent shall not be required with respect to any assignment by any Lender to an Affiliate of such Lender or to another Lender and (B) any Lender may at any time, without the consent of Exelon, the LC Issuer or the Administrative Agent, and without any requirement to have an Assignment and Acceptance executed, assign all or any part of its rights under this Agreement and any Note to a Federal Reserve Bank, provided that no such assignment shall release the transferor Lender from any of its obligations hereunder.

(b) By executing and delivering an Assignment and Acceptance, the Lender assignor thereunder and the assignee thereunder confirm to and agree with each other and the other parties hereto as follows: (i) other than as provided in such Assignment and Acceptance, such assigning Lender makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with this Agreement or the execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement or any other instrument or document furnished pursuant hereto; (ii) such assigning Lender makes no representation or warranty and assumes no responsibility with respect to the financial condition of any Borrower or the performance or observance by any Borrower of any of its obligations under this Agreement or any other instrument or document furnished pursuant hereto; (iii) such assignee confirms that it has received a copy of this Agreement, together with copies of the financial statements referred to in Section 4.01(e) and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into such Assignment and Acceptance; (iv) such assignee will, independently and without reliance upon the Administrative Agent, such assigning Lender or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement; (v) such assignee confirms that it is an Eligible Assignee; (vi) such assignee appoints and authorizes the Administrative Agent to take such action as agent on its behalf and to exercise such powers under this Agreement as are delegated to the Administrative Agent by the terms hereof, together with such powers as are reasonably incidental thereto; and (vii) such assignee agrees that it will perform in accordance with their terms all of the obligations which by the terms of this Agreement are required to be performed by it as a Lender.

(c) The Administrative Agent shall maintain at its address referred to in Section 8.02 a copy of each Assignment and Acceptance delivered to and accepted by it and a register for the recordation of the names and addresses of the Lenders and the Commitment Amount of, and principal amount of the Advances owing by each Borrower to, each Lender from time to time (the “Register”). The entries in the Register shall be conclusive and binding for all purposes, absent manifest error, and each Borrower, the Administrative Agent and the Lenders may treat each Person whose name is recorded in the Register as a Lender hereunder for all purposes of this Agreement. The Register shall be available for inspection by any Borrower or any Lender at any reasonable time and from time to time upon reasonable prior notice.

(d) Upon its receipt of an Assignment and Acceptance executed by an assigning Lender and an assignee representing that it is an Eligible Assignee, together with all Notes, if any, subject to such assignment, the Administrative Agent shall, if such Assignment and Acceptance has been completed and is in substantially the form of Exhibit C, (i) accept such Assignment and Acceptance, (ii) record the information contained therein in the Register and (iii) give prompt notice thereof to the Borrowers.

(e) Each Lender may sell participations to one or more banks or other entities (each, a “Participant”) in or to all or a portion of its rights and/or obligations under this Agreement (including all or a portion of its Commitment, the Advances owing to it, its participation in Facility LCs and any Note or Notes held by it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) such Lender

shall remain the holder of any such Note for all purposes of this Agreement, (iv) the Borrowers, the Administrative Agent and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement and (v) such Lender shall retain the sole right to approve, without the consent of any Participant, any amendment, modification or waiver of any provision of this Agreement or any Note held by such Lender, other than any such amendment, modification or waiver with respect to any Advance or Commitment in which such Participant has an interest that forgives principal, interest or fees or reduces the interest rate or fees payable with respect to any such Advance or Commitment, postpones any date fixed for any regularly scheduled payment of principal of, or interest or fees on, any such Advance or Commitment, extends any Commitment, releases any guarantor of any such Advance or releases any substantial portion of collateral, if any, securing any such Advance.

(f) Any Lender may, in connection with any assignment or participation or proposed assignment or participation pursuant to this Section 8.07, disclose to the assignee or participant or proposed assignee or participant, any information relating to the Borrowers furnished to such Lender by or on behalf of the Borrowers; provided that, prior to any such disclosure, the assignee or participant or proposed assignee or participant shall agree to preserve the confidentiality of any confidential information relating to the Borrowers received by it from such Lender (subject to customary exceptions regarding regulatory requirements, compliance with legal process and other requirements of law).

(g) If (i) any Lender shall make demand for payment under Section 2.11(a), 2.11(b) or 2.14, or (ii) shall deliver any notice to the Administrative Agent pursuant to Section 2.12 resulting in the suspension of certain obligations of the Lenders with respect to Eurodollar Rate Advances, then (in the case of clause (i)) within 60 days after such demand (if, but only if, such payment demanded under Section 2.11(a), 2.11(b) or 2.14 has been made by the applicable Borrower) or (in the case of clause (ii)) within 60 days after such notice (if such suspension is still in effect), as the case may be, the Borrowers may demand that such Lender assign in accordance with this Section 8.07 to one or more Eligible Assignees designated by the Borrowers and reasonably acceptable to the Administrative Agent all (but not less than all) of such Lender’s Commitment, the Advances owing to it and its participation in the Facility LCs within the next succeeding 30 days. If any such Eligible Assignee designated by the Borrowers shall fail to consummate such assignment on terms acceptable to such Lender, or if the Borrowers shall fail to designate any such Eligible Assignee for all of such Lender’s Commitment, Advances and participation in Facility LCs, then such Lender may (but shall not be required to) assign such Commitment and Advances to any other Eligible Assignee in accordance with this Section 8.07 during such period.

(h) Notwithstanding anything to the contrary contained herein, any Lender (a “Granting Bank”) may grant to a special purpose funding vehicle (an “SPC”), identified as such in writing from time to time by the Granting Bank to the Administrative Agent and the Borrowers, the option to provide to any Borrower all or any part of any Advance that such Granting Bank would otherwise be obligated to make to such Borrower pursuant to this Agreement; provided that (i) nothing herein shall constitute a commitment by any SPC to make any Advance, (ii) if an SPC elects not to exercise such option or otherwise fails to provide all or any part of such Advance, the Granting Bank shall be obligated to make such Advance pursuant

to the terms hereof. The making of an Advance by an SPC hereunder shall utilize the Commitment of the Granting Bank to the same extent, and as if, such Advance were made by such Granting Bank. Each party hereto hereby agrees that no SPC shall be liable for any indemnity or similar payment obligation under this Agreement (all liability for which shall remain with the Granting Bank). In furtherance of the foregoing, each party hereto hereby agrees (which agreement shall survive the termination of this Agreement) that, prior to the date that is one year and one day after the payment in full of all outstanding commercial paper or other senior indebtedness of any SPC, it will not institute against, or join any other person in instituting against, such SPC any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings under the laws of the United States or any State thereof. In addition, notwithstanding anything to the contrary contained in this Section 8.07, any SPC may (i) with notice to, but without the prior written consent of, the Borrower and the Administrative Agent and without paying any processing fee therefor, assign all or a portion of its interests in any Advances to the Granting Bank or to any financial institutions (consented to by such Borrower and Administrative Agent, neither of which consents shall be unreasonably withheld or delayed) providing liquidity and/or credit support to or for the account of such SPC to support the funding or maintenance of Advances and (ii) disclose on a confidential basis any non-public information relating to its Advances to any rating agency, commercial paper dealer or provider of any surety, guarantee or credit or liquidity enhancement to such SPC. This Section 8.07(h) may not be amended in any manner which adversely affects a Granting Bank or an SPC without the written consent of such Granting Bank or SPC.

SECTION 8.08 Governing Law. THIS AGREEMENT AND ALL NOTES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE COMMONWEALTH OF PENNSYLVANIA.

SECTION 8.09 Consent to Jurisdiction; Certain Waivers. (a) THE BORROWERS HEREBY IRREVOCABLY SUBMIT TO THE NON-EXCLUSIVE JURISDICTION OF THE COURTS OF THE COMMONWEALTH OF PENNSYLVANIA AND ANY UNITED STATES DISTRICT COURT SITTING IN THE COMMONWEALTH OF PENNSYLVANIA IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY NOTE AND THE BORROWERS HEREBY IRREVOCABLY AGREE THAT ALL CLAIMS IN RESPECT OF SUCH ACTION OR PROCEEDING MAY BE HEARD AND DETERMINED IN ANY SUCH COURT AND IRREVOCABLY WAIVE ANY OBJECTION THEY MAY NOW OR HEREAFTER HAVE AS TO THE VENUE OF ANY SUCH SUIT, ACTION OR PROCEEDING BROUGHT IN SUCH A COURT OR THAT SUCH COURT IS AN INCONVENIENT FORUM. NOTHING HEREIN SHALL LIMIT THE RIGHT OF THE ADMINISTRATIVE AGENT OR ANY LENDER TO BRING PROCEEDINGS AGAINST ANY BORROWER IN THE COURTS OF ANY OTHER JURISDICTION.

(b) EXCEPT AS PROHIBITED BY LAW, EACH PARTY HERETO HEREBY WAIVES ANY RIGHT IT MAY HAVE TO CLAIM OR RECOVER IN ANY LITIGATION ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY NOTE ANY SPECIAL, EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES OR ANY DAMAGES OTHER THAN, OR IN ADDITION TO, ACTUAL DAMAGES.

SECTION 8.10 Execution in Counterparts; Integration. This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. This Agreement constitutes the entire agreement and understanding among the parties hereto and supersedes all prior and contemporaneous agreements and understandings, oral or written, relating to the subject matter hereof.

SECTION 8.11 Liability Several. No Borrower shall be liable for the obligations of any other Borrower hereunder.

SECTION 8.12 Termination of Existing Agreement. The Borrowers and the Lenders which are parties to the Existing Agreement (which Lenders constitute the “Majority Lenders” as defined in the Existing Agreement) and Bank One, as Administrative Agent under the Existing Agreement, agree that, on the Closing Date, the commitments under the Existing Agreement shall terminate and be of no further force or effect (without regard to any requirement in Section 2.04 of the Existing Agreement for prior notice of termination of the commitments thereunder).

SCHEDULE I

PRICING SCHEDULE

The “Applicable Margin,” the “Facility Fee Rate,” the “Utilization Fee Rate” and the “LC Fee Rate” for any day are the respective percentages set forth below in the applicable row under the column corresponding to the Status that exists on such day:


Status	Applicable Margin and LC Fee Rate	Facility Fee Rate	Utilization Fee Rate
Level I	0.525%	0.125%	0.100%
Level II	0.600%	0.150%	0.125%
Level III	0.700%	0.175%	0.125%
Level IV	0.875%	0.250%	0.250%
Level V	1.200%	0.300%	0.500%

The Applicable Margin, the Facility Fee Rate, the Utilization Fee Rate and the LC Fee Rate shall be determined separately for each Borrower in accordance with the table above based on the Status for such Borrower. The Status in effect for any Borrower on any date for the purposes of this Pricing Schedule is based on the Xxxxx’x Rating and S&P Rating in effect at the close of business on such date.

For the purposes of the foregoing (but subject to the final paragraph of this Pricing Schedule):

“Level I Status” exists at any date for a Borrower if, on such date, such Borrower’s Xxxxx’x Rating is A3 or better or such Borrower’s S&P Rating is A- or better.

“Level II Status” exists at any date for a Borrower if, on such date, (i) Level I Status does not exist for such Borrower and (ii) such Borrower’s Xxxxx’x Rating is Baa1 or better or such Borrower’s S&P Rating is BBB+ or better.

“Level III Status” exists at any date for a Borrower if, on such date, (i) neither Level I Status nor Level II Status exists for such Borrower and (ii) such Borrower’s Xxxxx’x Rating is Baa2 or better or such Borrower’s S&P Rating is BBB or better.

“Level IV Status” exists at any date if, on such date, (i) none of Level I Status, Level II Status or Level III Status exists for such Borrower and (ii) such Borrower’s Xxxxx’x Rating is Baa3 or better or such Borrower’s S&P Rating is BBB- or better.

“Level V Status” exists at any date for a Borrower if, on such date, none of Level I Status, Level II Status, Level III Status or Level IV Status exists for such Borrower.

I-1

“Status” means Level I Status, Level II Status, Level III Status, Level IV Status or Level V Status.

If the S&P Rating and the Xxxxx’x Rating for a Borrower create a split-rated situation and the ratings differential is one level, the higher rating will apply. If the differential is two levels or more, the intermediate rating at the midpoint will apply. If there is no midpoint, the higher of the two intermediate ratings will apply. If a Borrower has no Xxxxx’x Rating or no S&P Rating, Level V Status shall exist for such Borrower.

FORM OF OPINION OF XXXXXXX XXXXX XXXXXXX & XXXXXXXXX

October 31, 2003

To each of the Agents and the Lenders which is a party

to the Credit Agreement, dated as of October 31,

2003, among Exelon Corporation, Commonwealth

Edison Company, PECO Energy Company and Exelon

Generation Company, LLC, as Borrowers, the various

financial institutions named therein, as Lenders and

Bank One, NA, as Administrative Agent

Re:

$750,000,000 Three-Year Credit Agreement

Ladies and Gentlemen:

This opinion letter is furnished to you pursuant to Section 3.01(v) of the $750,000,000 Three-Year Credit Agreement, dated as of October 31, 2003 (the “Agreement”), among Exelon Corporation (“Exelon”), Commonwealth Edison Company (“ComEd”), PECO Energy Company (“PECO”) and Exelon Generation Company, LLC (“Genco”), as Borrowers, the various financial institutions named therein, as Lenders and Bank One, NA, as Administrative Agent. Unless otherwise specified, terms defined in the Agreement are used herein as therein defined.

We have acted as special counsel for Exelon, Genco and PECO (collectively, the “Pennsylvania Borrowers”) in connection with the preparation, execution and delivery of the Agreement and as local counsel for ComEd with respect to certain matters of Pennsylvania law relating to the Agreement. In that capacity, we have examined the following:

(i) The Agreement, the Notes executed by Exelon (the “Exelon Notes”), the Notes executed by PECO (the “PECO Notes”), the Notes executed by Genco (the “Genco Notes”) and the Notes executed by ComEd (the “ComEd Notes” and, together with the Exelon Notes, the PECO Notes and the Genco Notes, the “Notes”);

(ii) The documents furnished by each of the Pennsylvania Borrowers pursuant to Section 3.01 of the Agreement;

(iii) The Articles of Incorporation of each of Exelon and PECO and all amendments thereto (in each case, its “Charter”);

D-1-1

(iv) The by-laws of each of Exelon and PECO and all amendments thereto (in each case, its “By-laws”);

(v) The Operating Agreement of Genco and all amendments thereto (the “Operating Agreement”);

(vi) A certificate from the Secretary of State of the Commonwealth of Pennsylvania dated October 29, 2003 certifying as to the subsistence of Exelon in Pennsylvania;

(vii) A certificate from the Secretary of State of the Commonwealth of Pennsylvania dated October 29, 2003 certifying as to the subsistence of PECO in Pennsylvania; and

(viii) A certificate from the Secretary of State of the Commonwealth of Pennsylvania dated October 29, 2003 certifying as to the subsistence of Genco in Pennsylvania;

We have also examined, and relied upon the accuracy of factual matters contained in, originals or copies, certified or otherwise identified to our satisfaction, of such other corporate or organizational records of the Pennsylvania Borrowers, certificates or comparable documents of public officials and of officers of the Pennsylvania Borrowers, and such other agreements, instruments and documents and have made such examinations of law as we have deemed necessary in connection with the opinions set forth below.

We have assumed the legal capacity and competence of natural persons, the genuineness of all signatures, the authenticity of all documents submitted to us as originals and the conformity to original documents of documents submitted to us as certified, conformed, photostatic, electronic or facsimile copies. We have made no independent factual investigation other than as described above, and as to other factual matters, we have relied exclusively on the facts stated in the representations and warranties contained in the Agreement and the Exhibits and Schedules to the Agreement (other than representations and warranties constituting conclusions of law on matters on which we opine). We have not examined any records of any court, administrative tribunal or other similar entity in connection with our opinion.

When an opinion or confirmation is given to our knowledge or with reference to matters of which we are aware or which are known to us, or with another similar qualification, the relevant knowledge or awareness is limited to the actual contemporaneous knowledge or awareness of facts, without investigation, by the lawyer who is the current primary contact for each of the Pennsylvania Borrowers and the individual lawyers in this firm who have participated in the specific transaction to which this opinion letter relates.

We have also assumed, without verification, (i) that the parties to the Agreement and the other agreements, instruments and documents executed in connection therewith, other than the Borrowers, have the power (including, without limitation, corporate power where applicable) and authority to enter into and perform the Agreement and such other agreements, instruments and documents, (ii) the due authorization, execution and delivery by such parties other than the Borrowers of

D-1-2

the Agreement and such other agreements, instruments and documents, (iii) that the Agreement and such other agreements, instruments and documents constitute legal, valid and binding obligations of each such party other than the Borrowers, enforceable against each such other party in accordance with their respective terms and (iv) the amount of a Borrower’s borrowings outstanding under the Agreement and the $750,000,000 3-Day Credit Agreement being entered into by the Borrower concurrently with this Agreement will not exceed the amount such Borrower is authorized to borrow under any approval referred to in Paragraphs 4 and 8 below.

D-1-3

Based upon the foregoing and subject to the assumptions, exceptions, limitations and qualifications set forth herein, we are of the opinion that:

1. Each of Exelon and PECO is a corporation duly incorporated and presently subsisting under the laws of the Commonwealth of Pennsylvania. Genco is a limited liability company duly formed and presently subsisting under the laws of the Commonwealth of Pennsylvania.

2. The execution and delivery, and the performance of the obligations thereunder, by the Pennsylvania Borrowers of the Agreement and the applicable Notes (a) are within the Pennsylvania Borrowers’ corporate or limited liability company powers, (b) have been duly authorized by all necessary corporate and limited liability company action of each of the Pennsylvania Borrowers, (c) do not contravene (i) the Charter, By-laws or the Operating Agreement, as the case may be, of each of the Pennsylvania Borrowers, (ii) any law of the United States or the Commonwealth of Pennsylvania or (iii) to our knowledge, any agreement or instrument to which any of the Pennsylvania Borrowers is a party or by which any of the Pennsylvania Borrowers is bound and (d) to our knowledge, do not result in or require the creation of any lien, security interest or other charge or encumbrance upon or with respect to any of the Pennsylvania Borrowers’ properties under such agreements or instruments.

3. The execution, delivery and performance by ComEd of the Agreement and the ComEd Notes do not contravene any law of the Commonwealth of Pennsylvania.

4. No consent or approval of, or notice to or filing with, any federal or state regulatory authority of the United States or the Commonwealth of Pennsylvania is required by the Pennsylvania Borrowers in connection with the execution or delivery by the Pennsylvania Borrowers of the Agreement or the applicable Notes, except for, in the case of Exelon and Genco, the authorization of the U.S. Securities and Exchange Commission under the Public Utility Holding Company Act of 1935 and, in the case of PECO, approval from the Public Utility Commission of the Commonwealth of Pennsylvania, which authorization and approval have been received and are in full force and effect.

5. The Agreement and the Exelon Notes have been duly executed and delivered by Exelon, and the Agreement and the Exelon Notes constitute the legal, valid and binding obligations of Exelon, enforceable against Exelon in accordance with their respective terms.

6. The Agreement and the PECO Notes have been duly executed and delivered by PECO, and the Agreement and the PECO Notes constitute the legal, valid and binding obligations of PECO, enforceable against PECO in accordance with their respective terms.

D-1-4

7. The Agreement and the Genco Notes have been duly executed and delivered by Genco, and the Agreement and the Genco Notes constitute the legal, valid and binding obligations of Genco, enforceable against Genco in accordance with their respective terms.

8. Assuming that the execution, delivery and performance of the Agreement and the ComEd Notes are within ComEd’s corporate power and the Agreement and the ComEd Notes have been duly authorized, executed and delivered by ComEd after receipt of all required governmental and regulatory approvals, the Agreement and the ComEd Notes constitute the legal, valid and binding obligations of ComEd, enforceable against ComEd in accordance with their respective terms.

9. None of the Pennsylvania Borrowers is an “investment company” or a company “controlled” by an “investment company” within the meaning of the Investment Company Act of 1940, as amended.

We do not have knowledge, after inquiry of each lawyer in this firm who is the current primary contact for the Borrowers or who has devoted substantive attention to matters on behalf of the Borrowers during the preceding twelve months and who is still currently employed by or a member of this firm, except as disclosed in Exelon’s Annual Report on Form 10-K for the year ended December 31, 2002 or Exelon’s Quarterly Report on Form 10-Q for the quarter ended September 30, 2003, no litigation or governmental proceeding is pending or threatened in writing against any Borrower (i) with respect to the Agreement or the Notes, or (ii) which is likely to have a material adverse effect upon the financial condition, business, properties or prospects of any Borrower and its subsidiaries taken as a whole.

The foregoing opinions are subject to the following exceptions, limitations and qualifications:

(a) Our opinions are subject to the effect of applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance, fraudulent transfer marshalling or similar laws affecting creditors’ rights and remedies generally; general principles of equity, including without limitation, concepts of materiality, reasonableness, good faith and fair dealing (regardless of whether such enforceability is considered in a proceeding in equity or at law); and limitations on enforceability of rights to indemnification or contribution by federal or state securities laws or regulations or by public policy.

(b) We draw your attention to the provisions of Section 911(b) of the Pennsylvania Crimes Code (the “Crimes Code”), 18 Pa. C.S.§ 911(b), in connection with the fact that the Advances bear floating rates of interest. Section 911(b) of the Crimes Codes makes it unlawful to use or invest income derived from a pattern of “racketeering activity” in the establishment or operation of any enterprise.

D-1-5

“Racketeering activity,” as defined in the Crimes Code, includes the collection of money or other property in full or partial satisfaction of a debt which arose as the result of the lending of money or other property at a rate of interest exceeding 25% per annum where not otherwise authorized by law.

(c) We express no opinion as to the application or requirements of federal or state securities (except with respect to the opinion in paragraph 9), patent, trademark, copyright, antitrust and unfair competition, pension or employee benefit, labor, environmental health and safety or tax laws in respect of the transactions contemplated by or referred to in the Agreement.

(d) We express no opinion as to the validity or enforceability of any provision of the Agreement or the Notes which (i) permits the Lenders to increase the rate of interest or to collect a late charge in the event of delinquency or default to the extent deemed to be penalties or forfeitures; (ii) purports to be a waiver by any Borrower of any right or benefit except to the extent permitted by applicable law; (iii) purports to require that waivers must be in writing to the extent that an oral agreement or implied agreement by trade practice or course of conduct modifying provisions of the Agreement or the Notes has been made; (iv) purports to exculpate any party from its own negligent acts; or (v) purports to authorize any Participant to set off and apply any deposits at any time held, and any other indebtedness at any time owing, by such Participant to or for the account of any Borrower.

We express no opinion as to the law of any jurisdiction other than the law of the Commonwealth of Pennsylvania and the federal law of the United States.

A copy of this opinion may be delivered by you to each financial institution that may become a Lender under the Agreement, and such persons may rely on this opinion as if it were addressed to them and had been delivered to them on the date hereof. This opinion may be relied on by you and such persons to whom you may deliver copies as provided in the preceding sentence only in connection with the consummation of the transactions described herein and may not be used or relied upon by you or any other person for any other purpose, without in each instance our prior written consent.

This opinion is limited to the matters expressly stated herein. No implied opinion may be inferred to extend this opinion beyond the matters expressly stated herein. We do not undertake to advise you or anyone else of any changes in the opinions expressed herein resulting from changes in law, changes in facts or any other matters that hereafter might occur or be brought to our attention.

Very truly yours,

FORM OF OPINION OF SIDLEY XXXXXX XXXXX & XXXX LLP

October 31, 2003

To each of the Agents and Lenders party to the Three

Year Credit Agreement dated as of October 31, 2003

among Exelon Corporation, Commonwealth Edison

Company, PECO Energy Company and Exelon

Generation Company, LLC, as Borrowers, the various

financial institutions named therein, as Lenders, and Bank

One, NA, as Administrative Agent

Ladies and Gentlemen:

We have been asked to furnish this letter to you pursuant to Section 3.01(b)(v) of the Three Year Credit Agreement dated as of October 31, 2003 (the “Credit Agreement”) among Exelon Corporation (“Exelon”), Commonwealth Edison Company (“ComEd”), PECO Energy Company (“PECO”) and Exelon Generation Company, LLC (“Genco”), as Borrowers, various financial institutions, as Lenders, and Bank One, NA, as Administrative Agent. Unless otherwise defined in this letter, capitalized terms defined in the Credit Agreement are used herein as therein defined.

We have acted as special Illinois counsel to ComEd in connection with the execution and delivery of the Credit Agreement and the Notes executed and delivered by ComEd (the “ComEd Notes”). In that capacity, we have examined:

(i) the Credit Agreement;

(ii) the ComEd Notes;

(iii) the Restated Articles of Incorporation of ComEd and all amendments thereto (the “ComEd Charter”); and

(iv) the by-laws of ComEd and all amendments thereto (the “ComEd By-Laws”).

We are familiar with the corporate proceedings taken by ComEd in connection with the Credit Agreement and the transactions contemplated thereby. For purposes of expressing the opinions expressed in this letter, we have relied, as to various questions of fact material thereto, upon the representations made by ComEd in the Credit Agreement and upon certificates of officers of ComEd. We have also examined originals, or copies of originals certified to our satisfaction, of such corporate records of ComEd and such agreements, documents, certificates and other statements of government officials and other instruments, have examined such questions of law and have satisfied ourselves as to such matters of fact as we have considered relevant and necessary as a basis for this letter. We have

D-2-1

assumed the genuineness of all signatures, the legal capacity of all natural persons, the authenticity of all documents submitted to us as originals and the conformity with the original documents of all documents submitted to us as certified or photostatic copies or by facsimile or other means of electronic transmission. We have also assumed that the amount of ComEd’s borrowings outstanding under the Credit Agreement and the 364-Day Credit Agreement dated as of October 31, 2003 among Exelon, ComEd, PECO and Genco, as Borrowers, various financial institutions, as Lenders, and Bank One, NA, as Administrative Agent, will not exceed the amount that ComEd is authorized to borrow under any approval referred to in paragraph 5. With respect to any instrument or agreement executed or to be executed by any party other than ComEd, we have assumed, to the extent relevant to the opinions set forth herein, that (i) such other party (if not a natural person) has been duly organized and is validly existing and in good standing under the laws of its jurisdiction of organization and (ii) such other party has full right, power and authority to execute, deliver and perform its obligations under each instrument or agreement to which it is a party and each such instrument or agreement has been duly authorized (if applicable), executed and delivered by, and is a valid, binding and enforceable agreement or obligation, as the case may be, of, such other party.

Based upon the foregoing and subject to the qualifications and limitations stated below, it is our opinion that:

1. ComEd is a corporation duly organized, validly existing and in good standing under the laws of the State of Illinois.

2. The execution and delivery by ComEd of, and performance by ComEd of its obligations under, the Credit Agreement and the ComEd Notes are within its corporate powers, have been duly authorized by all necessary corporate action, and do not (a) violate any provision of the ComEd Charter, the ComEd By-laws or any law, rule or regulation known to us to be customarily applicable to transactions of the nature contemplated by the Credit Agreement or the ComEd Notes or (b) to our knowledge, breach, constitute a default under or otherwise violate any agreement or instrument to which ComEd is a party or by which it or its properties are bound; and such execution, delivery and performance do not, to our knowledge, result in or require the creation of any lien, security interest or encumbrance on or in any of ComEd’s properties.

3. The Credit Agreement and the ComEd Notes have been duly executed and delivered by ComEd.

4. The Credit Agreement and the ComEd Notes are, to the extent that the laws of the State of Illinois or the federal laws of the United States are applicable to the enforcement of ComEd’s obligations thereunder, legal, valid and binding obligations of ComEd, enforceable against ComEd in accordance with their respective terms, except to the extent enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance or other similar laws of general applicability relating to or affecting the enforceability of creditors’

D-2-2

rights generally, and by the effect of general principles of equity (regardless of whether enforceability is considered in a proceeding at law or in equity).

5. No authorization, approval or other action by, and no notice to or filing with, any governmental authority or regulatory body of the United States or the State of Illinois is required for the due execution and delivery by ComEd of, and performance by ComEd of its obligations under, the Credit Agreement and the ComEd Notes, except for (i) the authorization of the U.S. Securities and Exchange Commission under the Public Utility Holding Company Act of 1935, as amended, which authorization has been received, and (ii) the approval of the Illinois Commerce Commission under the Illinois Public Utilities Act, as amended, which approval has been received.

6. ComEd is not an “investment company” within the meaning of the Investment Company Act of 1940, as amended (“Investment Company Act”).

We confirm to you that, to our knowledge, after inquiry of each lawyer in this firm who currently has supervisory responsibility for matters handled by this firm on behalf of ComEd, except as disclosed in ComEd’s Annual Report on Form 10-K for the year ended December 31, 2002 and its Quarterly Reports on Form 10-Q for the quarterly periods ended March 31, 2003 and June 30, 2003, there is no pending or overtly threatened action or proceeding to which ComEd or any of its Subsidiaries is a party before any court, governmental agency or arbitrator that relates to the Credit Agreement or the ComEd Notes or that could reasonably be expected to affect materially and adversely ComEd’s performance of its obligations under the Credit Agreement or the ComEd Notes.

The opinion as to enforceability set forth in paragraph 4 above is subject to the qualification that the enforceability of ComEd’s obligations under the Credit Agreement and the ComEd Notes is subject to general principles of equity (regardless of whether such enforceability is considered in a proceeding at law or in equity). Such principles of equity are of general application and, in applying such principles, a court, among other things, might not allow a contracting party to exercise remedies in respect of a default deemed immaterial, or might decline to order an obligor to perform covenants. Such principles would include an expectation that parties act with reasonableness and in good faith, and might be applied, for example, to provisions which purport to grant a party with the authority to exercise sole discretion or make conclusive determinations. We note further, that, in addition to the application of equitable principles described above, courts have imposed an obligation on contracting parties to act reasonably and in good faith in the exercise of their contractual rights and remedies, and may also apply public policy considerations in limiting the rights of parties seeking to obtain indemnification.

With respect to our opinion in paragraph 6 above that ComEd is not an “investment company” within the meaning of the Investment Company Act, we have relied exclusively, as to all factual matters, on a certificate, dated as of the date of this letter (the “Certificate”), of J. Xxxxx Xxxxxxxx, Vice President and Treasurer of ComEd (the “Executing Officer”). We note that, for purposes of determining whether a particular entity is an “investment company” within the meaning of the Investment Company Act, it is necessary to examine the “value” of the assets of such entity within

D-2-3

the meaning of Section 2(a)(41)(A) of the Investment Company Act. Section 2(a)(41)(A)(ii) of the Investment Company Act provides that the “value” of certain assets held by an entity shall be the “fair value” of such assets as determined in good faith by such entity’s board of directors (or similar governing body). Although the Certificate makes certain certifications regarding the value of the assets of ComEd and certain of its subsidiaries, the Executing Officer did not request the Board of Directors of ComEd or of any of such subsidiaries to determine the value of any assets required to be valued at “fair value” pursuant to Section 2(a)(41)(A)(ii), but obtained values from other sources he deemed to be reliable. We have assumed, however, with your permission, that all assets of ComEd and its subsidiaries that are required to be valued at “fair value” pursuant to Section 2(a)(41)(A)(ii) of the Investment Company Act by the Board of Directors of ComEd or of the relevant subsidiary, as the case may be, would have been valued at the same values ascribed to such assets in the Certificate had the Board of Directors of ComEd or of the relevant subsidiary determined the “fair value” thereof pursuant to said section.

We express no opinion as to the enforceability of provisions of the Credit Agreement that (a) attempt to exculpate other parties from liability for future actions, inactions or practices, (b) purport to establish evidentiary standards, (c) purport to confer subject matter jurisdiction on any court or fix venue, (d) relate to severability or separability, (f) relate to payment without set-off or that otherwise purport to make obligations of, or determinations by, any party unconditional and absolute or (g) constitute agreements to agree. We also express no opinion as to the enforceability of provisions in the Credit Agreement to the effect that terms may not be waived or modified except in writing.

Any opinion or statement herein which is expressed to be “to our knowledge” or is otherwise qualified by words of like import means that the lawyers in this firm who have had an involvement in reviewing the Credit Agreement and the ComEd Notes have no current conscious awareness of any facts or information contrary to such opinion or statement.

This letter is limited to the federal laws of the United States of America and the laws of the State of Illinois. We note that the Credit Agreement and each of the ComEd Notes provides that it is to be governed by the laws of the Commonwealth of Pennsylvania. We express no opinion as to (i) Exelon, PECO or Genco or (ii) the enforceability under the laws of the Commonwealth of Pennsylvania of ComEd’s obligations under the Credit Agreement or the ComEd Notes. With respect to these matters, we understand you are relying upon the opinion of Xxxxxxx Xxxxx Xxxxxxx & Xxxxxxxxx LLP, special counsel to Exelon, PECO and Genco and special Pennsylvania counsel to ComEd.

This letter is being delivered solely for the benefit of the persons to whom it is addressed; accordingly, it may not be relied upon by any other person or otherwise circulated or utilized for any purpose without our written consent, except that Xxxxxxx Xxxxx Xxxxxxx & Xxxxxxxxx LLP may rely upon the opinions expressed in paragraphs 1 through 3 (inclusive) in rendering their opinion to you of even date herewith. This letter may not be quoted or filed with any governmental authority or other regulatory agency (except to the extent required by law). We assume no obligation to update or supplement the opinions expressed herein to reflect any facts or circumstances which may hereafter

come to our attention with respect to such opinions, including any changes in applicable law which may hereafter occur.

Very truly yours,

SIDLEY XXXXXX XXXXX & XXXX LLP
