(f) Such election must be made prior to any date that each of the Companies must communicate to the MISO the method by which it will satisfy its Ancillary Services obligation, however, notwithstanding any of the foregoing, all necessary arrangements must be completed prior to the initial date of delivery under this Agreement;

(g) For each Ancillary Service (as represented by a specific MISO Tariff Schedule) for which the BGS-FP Supplier elects to provide resources to allow each of the Companies to self-supply, such election shall encompass 100% of the applicable requirement that the BGS-FP Supplier is responsible for under this Agreement; and

(h) For each Ancillary Service (as represented by a specific MISO Tariff Schedule) for which the BGS-FP Supplier elects to provide resources to allow each of the Companies to self-supply, such election shall remain effective for the entire Term of this Agreement.

ARTICLE 4. COMMENCEMENT AND TERMINATION OF AGREEMENT

4.1 Term and Delivery Period

This Agreement shall become effective as of the Effective Date and shall continue in effect for a period ending at the end of HE 2400 CPT on the Termination Date (the “Term”) provided, however, that: (i) termination of this Agreement for any reason shall not relieve any of the Companies or the BGS-FP Supplier of any obligation accrued or accruing prior to such termination, (ii) applicable provisions of this Agreement shall continue in effect after termination to the extent necessary to provide for final ▇▇▇▇▇▇▇▇, settlements, payments and adjustments, (iii) termination of this Agreement for an Event of Default shall not deprive the Non-Defaulting Party of its rights and remedies to recover its full damages as provided elsewhere in this Agreement, and (iv) those provisions designated or described in Sections 14.2 and 15.13(iii) shall survive termination.

The provision of BGS-FP Supply shall commence at the beginning of HE 0100 CPT on the Delivery Start Date and shall end at the end of HE 2400 CPT on the Termination Date (the “Delivery Period”).

4.1.a Early Termination

This Agreement may be terminated in whole or in part prior to the Natural Termination Date pursuant to the following:

(i) By mutual agreement of one or more of the Companies and the BGS-FP Supplier, as provided in Section 4.2;

(ii) By one or more of the Companies or the BGS-FP Supplier, as provided in Sections 5.2 and 5.4; or

(iii) By the decision of any Party to terminate any other agreement between the Parties for the provision of BGS Supply, as provided in Section 5.4.e;

provided, however, that if this Agreement is terminated with respect to one or more of the Companies, any reference in the Agreement to “each of the Companies” shall refer to any remaining Company or Companies.

If this Agreement is terminated pursuant to the provisions of clauses (i), (ii) or (iii) above, the effective date of such termination shall be deemed the Early Termination Date. Early Termination gives rise to the Non-Defaulting Party’s rights and remedies under Articles 4 and 5. The Parties further agree that no Party shall have the right to terminate this Agreement based solely on: (a) the BGS-FP Supplier’s ability to sell the Capacity and/or Energy hereunder for a price greater than the price one or more of the Companies is paying the BGS-FP Supplier hereunder; or (b) one or more of the Companies’ ability to purchase the Capacity and/or Energy hereunder at a price less than the price one or more of the Companies is paying the BGS-FP Supplier hereunder.

4.1.b Termination of Right to Supply BGS-FP

The BGS-FP Supplier agrees that, notwithstanding any provision of this Agreement to the contrary, termination of this Agreement for reason of an Event of Default by the BGS-FP Supplier shall terminate any right of the BGS-FP Supplier to provide BGS-FP Supply to each Company to which the BGS-FP Supplier has defaulted and thereafter nullify any of the entitlements to which the BGS-FP Supplier became entitled as a result of being selected as a winning bidder in the Illinois Auction (including, without limitation, the right to register as a Market Participant for the Delivery Points) for such Company or Companies. Provided, however, nothing in this subsection shall be construed to prevent the BGS-FP Supplier from receiving the benefits of this Agreement, to which it is entitled as of the Termination Date, including the right to receive a Termination Payment if one is due to the BGS-FP Supplier upon such termination.

4.2 Mutual Termination

One or more of the Companies and the BGS-FP Supplier may agree at any time during the Term to terminate their respective rights and obligations hereunder on such terms and under such conditions that they mutually deem to be appropriate as set forth in a mutual termination agreement reasonably acceptable in form and substance to such Company or Companies and the BGS-FP Supplier (“Mutual Termination Agreement”); provided, however, that each of the Companies agrees that it shall enter into a Mutual Termination Agreement which will discharge the BGS-FP Supplier with respect to liabilities arising after the effective date of the Mutual Termination Agreement if the following conditions precedent are met: (i) the BGS-FP Supplier identifies a replacement supplier willing to assume all obligations of the BGS-FP Supplier hereunder for the remaining Term (the “Replacement BGS-FP Supplier”); (ii) the Replacement BGS-FP Supplier demonstrates to the satisfaction of each of the Companies its compliance with Article 6, as of the effective date of the Mutual Termination Agreement; (iii) the Replacement BGS-FP Supplier executes a counterpart signature page to this Agreement and thereby becomes a Party under this Agreement, effective immediately following the effective date of the Mutual Termination Agreement; and (iv) the BGS-FP Supplier is not, to the belief or knowledge of any of the Companies, subject to an Event of Default as of the effective date of the Mutual Termination Agreement or, if one or more of the Companies believes that the BGS-FP Supplier may be subject to an Event of Default, either (a) each of the Companies has determined that, as of the effective date of the Mutual Termination Agreement, it has not incurred any Damages as a result of the Event of Default or (b) if one or more of the Companies has determined, as of the effective date of the Mutual Termination Agreement, that it may have incurred Damages as a result of the Event of Default, that the Replacement BGS-FP Supplier has agreed in writing to be responsible for the payment of such Damages or to otherwise cure the Event of Default, in either case to the satisfaction of the Company or Companies which suffers or suffer the detriment or burden of such default.

4.3 Forward Contract and Master Netting Agreement

The Parties acknowledge that this Agreement is a Forward Contract and Master Netting Agreement, the Parties are Forward Contract Merchants and Master Netting Agreement Participants with respect to this Agreement, and, accordingly, the Parties hereto are entitled to the protections of the Safe Harbor Provisions of the Bankruptcy Code. The Parties therefore agree that this Agreement may be terminated and the remedies hereunder exercised by either

Party upon the commencement of a proceeding by the other Party under any chapter of the Bankruptcy Code, and that the automatic stay of Section 362(a) of the Bankruptcy Code shall not apply to such termination or to the exercise of the remedies set forth herein.

No Event of Default shall serve to terminate this Agreement unless and until the Non-Defaulting Party provides the notice specified in Section 5.2(ii).

5.2 Rights Upon Default

Upon and during the continuation of an Event of Default, the Non-Defaulting Party shall be entitled to elect or pursue one or more of the following remedies:

(i) pursue any and all available legal and equitable remedies;

(ii) designate a day, no earlier than the day notice of such designation is effective and no later than twenty (20) days after notice of such designation is effective, as a date for Early Termination (“Early Termination Date”) with respect to the obligations of the Defaulting Party without any liability or responsibility whatsoever except for obligations arising prior to the Early Termination Date and except for the determination and payment of the Termination Payment as provided in Section 5.4, by providing written notice to the Defaulting Party.

In the event that a Non-Defaulting Party elects to designate an Early Termination Date with respect to the obligations of a Defaulting Party, the rights, liabilities, powers and obligations of any other Non-Defaulting Party shall survive such termination if the Early Termination is applicable to one or more but not all of the Companies;

5.3 Damages Resulting from an Event of Default

Damages resulting from one or more of the following shall include all costs incurred by a Company, acting in a commercially reasonable manner consistent with any statutory or regulatory requirements imposed by the Applicable Legal Authorities, in obtaining replacement services or in obtaining a replacement supplier, which costs exceed the amounts that would have been payable to the defaulting BGS-FP Supplier under this Agreement:

(i) the BGS-FP Supplier’s failure:

(a) to provide BGS-FP Supply in accordance with this Agreement,

(b) to pay the MISO for purchases of any products or services from the MISO,

(d) to otherwise fail to comply with MISO requirements;

such that the MISO holds one or more of the Companies responsible for the provision of Energy (including all charges for Energy Losses, Energy Imbalance Service, and congestion), Resource Adequacy Requirements or Capacity to meet the BGS-FP Supplier Responsibility Share under this Agreement; or

(ii) the occurrence of any Event of Default attributable to the BGS-FP Supplier resulting in Early Termination.

5.3.b Damages

Costs incurred by one or more of the Companies for the purpose of calculating Damages include, but are not limited to, the following costs incurred by or assessed on one or more of the Companies as a result of the failure of the BGS-FP Supplier to satisfy its obligations under this Agreement:

(i) the cost of Energy (including all charges for Energy Losses, Energy Imbalance Service, and congestion), Resource Adequacy Requirements, Capacity or other elements of BGS-FP Supply allocated to one or more of the Companies by the MISO due to the failure of the BGS-FP Supplier to meet obligations owing to the MISO in connection with its obligations under this Agreement;

(ii) the cost of Energy (including all charges for Energy Losses, Energy Imbalance Service, and congestion), Resource Adequacy Requirements or Capacity purchased by one or more of the Companies to replace BGS-FP Supply that the BGS-FP Supplier was obligated, but failed, to supply pursuant to this Agreement;

(iii) administrative and legal costs associated with procuring the replacement BGS-FP Supply identified in the foregoing clause; and

(iv) financial hedging costs incurred by one or more of the Companies on behalf of BGS-FP Customers as a result of having to procure BGS-FP Supply that the BGS-FP Supplier was obligated, but failed, to supply pursuant to this Agreement.

Damages calculated hereunder shall constitute the ultimate liability of the BGS-FP Supplier in the event of an Early Termination caused by an Event of Default attributable to the BGS-FP Supplier regardless of the reason or basis for such Early Termination.

5.3.c Failure By one or more of the Companies to Accept BGS-FP Supply Tendered by the BGS-FP Supplier

Damages resulting from the failure of one or more of the Companies to accept BGS-FP Supply tendered by the BGS-FP Supplier necessary to meet the BGS-FP Supplier Responsibility Share of BGS-FP Load under this Agreement shall consist of the positive difference (if any) between the amounts that would have been payable to the BGS-FP Supplier hereunder had such Company or Companies accepted the BGS-FP Supply tendered by the

BGS-FP Supplier necessary to meet the BGS-FP Supplier Responsibility Share of BGS-FP Load under this Agreement minus the amount realized by the BGS-FP Supplier in disposing, in a reasonable commercial manner, of the BGS-FP Supply not accepted by such Company or Companies; provided, however, that none of the Companies shall be required to accept quantities of Energy, Capacity or any other component of BGS-FP Supply utilized by Customers on an instantaneous basis as a function of electrical load, in excess of such Customer’s instantaneous consumption of such component of BGS-FP Supply.

5.3.d Damages Resulting from Early Termination due to an Event of Default Attributable to one or more of the Companies

Damages resulting from Early Termination due to an Event of Default attributable to one or more of the Companies shall be as set forth in Section 5.4. Damages calculated in accordance with Section 5.4 shall be the exclusive remedy available to the BGS-FP Supplier in the event of Early Termination resulting from an Event of Default attributable to one or more of the Companies.

5.4 Calculation of Settlement Amount and Termination Payment

5.4.a Settlement Amount

After the Non-Defaulting Party has provided the notice specified in Section 5.2(ii), the Non-Defaulting Party shall calculate, in a commercially reasonable manner and consistent with the calculation of Damages in this Agreement, a Settlement Amount under this Agreement. For the purposes of such determination, the quantities of BGS-FP Supply provided for under this Agreement for the period following the Early Termination Date through the Natural Termination Date shall be deemed to be those quantities that would have been delivered on an hourly basis to the Affected Company or Companies had this Agreement been in effect during the previous calendar year, adjusted for such BGS-FP Load changes as may have occurred since the previous calendar year.

5.4.b Net Out of Settlement Amounts

The Non-Defaulting Party shall calculate a “Termination Payment” by aggregating all Settlement Amounts due under this Agreement or any other agreement(s) between the Affected Company or Companies and the BGS-FP Supplier for the provision of

BGS Supply into a single amount by: netting out (a) all Settlement Amounts that are due or will become due to the Defaulting Party, plus, at the option of the Non-Defaulting Party, any cash or other form of security then available to the Non-Defaulting Party and actually received, liquidated and retained by the Non-Defaulting Party, plus any or all other amounts due to the Defaulting Party under this Agreement or any other agreement(s) between the Affected Company or Companies and the BGS-FP Supplier for the provision of BGS Supply against (b) all Settlement Amounts that are due or will become due to the Non-Defaulting Party, plus any or all other amounts due to the Non-Defaulting party under this Agreement or any other agreement(s) between the Affected Company or Companies and the BGS-FP Supplier for the provision of BGS Supply, so that all such amounts shall be netted out to a single liquidated amount; provided, however, that if the BGS-FP Supplier is the Defaulting Party and the Termination Payment is due to the BGS-FP Supplier, the appropriate Company or Companies shall be entitled to retain a commercially reasonable portion of the Termination Payment, which may be equal to the entire amount of the Termination Payment, as security for additional amounts that may be determined to be due and owing by the BGS-FP Supplier as Damages and further provided that any previously attached security interest of a Company in such retained amounts shall continue. Any portion of the Termination Payment not retained by a Company as security shall be immediately due and owing to the BGS-FP Supplier as an estimate of the amounts ultimately determined to be due and owing.

The Parties recognize, however, the final calculation of Settlement Amounts hereunder may not be known for some time since the level of such Settlement Amounts may be dependent upon the arrangements made by the Affected Company or Companies to obtain replacement services or a replacement supplier. Each of the Companies and the BGS-FP Supplier agree that, until the calculation of Settlement Amounts under this provision is completed, the amount and payment to the Affected Company or Companies of the Termination Payment shall be immediately due and owing as an estimate of the amounts ultimately determined to be due and owing. After Settlement Amounts have been finally determined under this Section 5.4, the amounts due and owing will be reconciled with payments already made by the BGS-FP Supplier. The Termination Payment shall be due to or due from the Non-Defaulting Party as appropriate. If the Termination Payment has been retained by the Affected Company or Companies as security for additional amounts that may be determined to be due and owing by the BGS-FP Supplier, and if, upon making a final determination of Settlement Amounts, the Termination Payment, or any portion thereof, is to be made to the BGS-FP Supplier, the

Affected Company or Companies will pay simple (not compounded) interest on the retained portion of the Termination Payment to the BGS-FP Supplier. Simple interest will be calculated at the lower of the Interest Index or six (6) percent per annum.

5.4.c Notice of Termination Payment

As soon as practicable after calculation of a Termination Payment, notice shall be given by the Non-Defaulting Party to the Defaulting Party of the amount of the Termination Payment and whether the Termination Payment is due to or due from the Non-Defaulting Party. The notice shall include a written statement explaining in reasonable detail the calculation of such amount. Subject to the Affected Company’s or Companies’ right to retain a commercially reasonable portion of the Termination Payment as set forth in Section 5.4.b, the Termination Payment shall be made by the Party that owes it within three (3) Business Days after such notice is effective.

5.4.d Disputes with Respect to Termination Payment

If the Defaulting Party disputes the Non-Defaulting Party’s calculation of the Termination Payment, in whole or in part, the Defaulting Party shall, within three (3) Business Days of the effective date of notice of the Non-Defaulting Party’s calculation of the Termination Payment, provide to the Non-Defaulting Party a detailed written explanation of the basis for such dispute; provided, however, that if the Termination Payment is due from the Defaulting Party, the Defaulting Party shall first provide commercially reasonable financial assurances to the Non-Defaulting Party in an amount equal to the Termination Payment.

5.4.e Multiple BGS Supply Agreements

It is the intention of each of the Companies and the BGS-FP Supplier that, in the event the BGS-FP Supplier is a party to other agreements with one or more of the Companies for the provision of BGS Supply that existed prior to the Effective Date or is entered into concurrent with or after the Effective Date, the decision by the Non-Defaulting Party to terminate its obligations to the Defaulting Party pursuant to Section 5.2 of this Agreement shall result in the automatic termination of its obligations under all agreements between the Affected Company or Companies and the BGS-FP Supplier for the provision of BGS Supply. The Non-Defaulting Party will calculate a single Termination Payment applicable to all such agreements as set forth herein. Each Party hereby agrees that such other agreements are deemed amended by this Agreement for the purpose of calculating a single Termination Payment as described herein.

5.4.f Reliance on Netting

(i) The Parties are making credit, default, collateral and other decisions and changes based upon and in reliance on the effectiveness of the default, early termination, setoff and netting provisions of this Agreement and other BGS Supply agreements, including and, in particular, the calculation of the Total Exposure Amount for purposes of determining when and how much Margin collateral must be posted. The Parties would not enter into this Agreement and change their position with regard to netting to determine Total Exposure Amounts, Margin collateral requirements and other matters except for their reliance on and with the understanding that these netting terms will be effective.

(ii) Notwithstanding anything else in this Agreement or in any other agreement between the Parties to the contrary, if for any reason these terms or any right of offset or netting hereunder or under another BGS Supply agreement in favor of the Non-Defaulting Party against a bankrupt Defaulting Party is delayed from being exercised or is not enforceable in accordance with its terms because a Party asserts or is concerned that the Safe Harbor Provisions of the Bankruptcy Code do not apply to such rights of enforcement or for any other reason, the Non-Defaulting Party may (a) exercise its rights to effect a setoff under Section 553 of the Bankruptcy Code or other applicable provisions, equity and law, and (b) withhold payments subject to a claim of offset under any obligations due the Defaulting Party in respect of any transactions or deliveries under this Agreement or any other BGS Supply agreement until such setoff rights are exercised and effected.

5.5 Setoff of Payment Obligations of the Non-Defaulting Party

Any payment obligations of the Non-Defaulting Party to the Defaulting Party pursuant to this Agreement or any other agreement(s) between one or more of the Companies and the BGS-FP Supplier for the provision of BGS Supply, Energy or Capacity shall be set off: (i) first, to satisfy any payment obligations of the Defaulting Party to the Non-Defaulting Party pursuant to this Agreement or any other agreement(s) between such Company(ies) and the BGS-FP Supplier for the provision of BGS Supply, Energy or Capacity that are unsecured and not subject to any Guaranty; (ii) second, to satisfy any payment obligations of the Defaulting Party to the Non-Defaulting Party pursuant to this Agreement or any other agreement(s) between

such Company(ies) and the BGS-FP Supplier for the provision of BGS Supply, Energy or Capacity that are unsecured, but which are subject to a Guaranty; and (iii) third, to satisfy any remaining payment obligations of the Defaulting Party to the Non-Defaulting Party pursuant to this Agreement or any other agreement(s) between such Company(ies) and the BGS-FP Supplier for the provision of BGS Supply, Energy or Capacity. Any setoff shall not be subject to the automatic stay by virtue of Section 362(b)(6) of the Bankruptcy Code.

5.6 Preservation of Rights of the Non-Defaulting Party

The rights of the Non-Defaulting Party under this Agreement, including without limitation Sections 5.4 and 5.5, shall be supplemental to, and not in lieu of, any right of recoupment, lien, or set-off afforded by applicable law, and all such rights are expressly preserved for the benefit of the Non-Defaulting Party.

5.7 Forward Contract Merchant and Master Netting Agreement Participant

The Parties acknowledge that the BGS-FP Supplier and each of the Companies are Forward Contract Merchants and Master Netting Agreement Participants. By virtue of Section 546(e) of the Bankruptcy Code, any Margin payments, settlement payments or posting of Margin collateral are not avoidable and the Parties are otherwise entitled to the benefits of the Safe Harbor Provisions of the Bankruptcy Code with respect to such payments or collateral.

5.8 Integrated Transaction

To the extent that Section 365 of the Bankruptcy Code applies to this Agreement, the Parties agree that all transactions with each of the Companies under this Agreement and other agreements between each such Company and the BGS-FP Supplier for the provision of BGS Supply constitute one integrated transaction that can only be assumed or rejected in its entirety.

ARTICLE 6. CREDITWORTHINESS

6.1 Applicability

The BGS-FP Supplier agrees that it shall meet the creditworthiness standards of this Article 6 at all times during the Term. Without limitation of the foregoing, the BGS-FP Supplier shall, upon written request by one or more of the Companies, affirmatively demonstrate its compliance with the creditworthiness standards set forth hereunder. Such Company or

Companies may establish less restrictive creditworthiness standards under this Article 6 in a non-discriminatory manner and may subsequently restore such credit requirements to a level not to exceed their original level in a non-discriminatory manner as circumstances permit.

6.2 Creditworthiness Determination

The BGS-FP Supplier may submit and maintain a security deposit in lieu of submitting to or being qualified under a creditworthiness evaluation. The BGS-FP Supplier shall have the opportunity to petition the Companies to re-evaluate its creditworthiness whenever an event occurs that the BGS-FP Supplier believes would improve the determination made by the Companies of its creditworthiness. The Companies’ credit re-evaluation must be completed as soon as possible but no later than thirty (30) days after receiving a fully documented request. The Companies must provide the rationale for their determination of the Credit Limit and any resulting security requirement. The Companies must perform their credit re-evaluation and associated security calculation in a non-discriminatory manner. The BGS-FP Supplier shall provide unrestricted access to audited financial statements of the BGS-FP Supplier or the Guarantor, as the case may be, if such audited financial statements are not available on ▇▇▇▇▇ at ▇▇▇▇://▇▇▇.▇▇▇.▇▇▇/▇▇▇▇▇.▇▇▇▇▇; provided, however, that if audited financial statements are not available, the Companies may accept other types of financial statements. In the event that the BGS-FP Supplier relies upon a Guarantor, the creditworthiness determination provided for by this section shall apply to the Guarantor.

6.3 MtM Exposure Amount Methodology

To calculate the daily exposure for the BGS-FP Supplier, the MtM Exposure Amount methodology will be used. That methodology is described in Appendix D.

6.4 Credit Limit

The following criteria constitute the Companies’ creditworthiness requirements for the BGS-FP Supplier to cover the Total Exposure Amount. In all instances, the most current senior unsecured debt rating (or, if unavailable, issuer rating from ▇▇▇▇▇’▇ or corporate issuer rating discounted one notch from S&P or Fitch) will be used.

(i) The following requirements shall apply in the event the BGS-FP Supplier or its Guarantor has been incorporated or otherwise formed under the laws of the United States. If the BGS-FP Supplier cannot meet the following requirements, it shall be required to post cash or a Letter of Credit for the Total Exposure Amount.

(a) If the BGS-FP Supplier chooses not to rely on a Guarantor to satisfy the requirements of this Section 6.4(i), the requirements of this subsection 6.4(i)(a) shall apply. For the BGS-FP Supplier to be granted an unsecured line of credit, the BGS-FP Supplier: (1) must be rated by at least two of the following rating agencies: S&P, ▇▇▇▇▇’▇ or Fitch, and (2) must have a minimum senior unsecured debt rating of at least “BBB-” from S&P, “Baa3” from ▇▇▇▇▇’▇ or “BBB-” from Fitch. In the event that senior unsecured debt ratings are unavailable for S&P and Fitch, the corporate issuer rating, discounted one notch, will be used. In the event that senior unsecured debt ratings are unavailable from ▇▇▇▇▇’▇, the issuer rating will be used. The Companies will only rely on senior unsecured debt ratings, or if unavailable, issuer or corporate issuer ratings. If the BGS-FP Supplier does not have a senior unsecured debt rating and does not have an issuer or corporate issuer rating from a rating agency, it will be deemed by the Companies not to be rated by that rating agency. If the BGS-FP Supplier is rated by only two rating agencies, and the ratings are split, the lowest rating will be used. If the BGS-FP Supplier is rated by three rating agencies, and the ratings are split, the lower of the two highest ratings will be used; provided, however, that in the event that the two highest ratings are common such common rating will be used (the process described in this subsection 6.4(i)(a) referred to as the “Minimum Rating”). The maximum level of the Credit Limit to cover the Total Exposure Amount will be determined in accordance with Table A:

Table A


Credit Rating of the BGS-FP Supplier or the Guarantor			Credit Limit to be calculated as the lesser of the % of TNW and Credit Limit Cap below
S&P	▇▇▇▇▇’▇	Fitch	TNW %	Credit Limit Cap*
A-and above	A3 and above	A-and above	16% of TNW	$	80,000,000
BBB+	Baa1	BBB+	10% of TNW	$	60,000,000
BBB	Baa2	BBB	8% of TNW	$	40,000,000
BBB-	Baa3	BBB-	6% of TNW	$	20,000,000
Below BBB-	Below Baa3	Below BBB-	0% of TNW	$	0

*	For BGS-FP Suppliers relying on a Guarantor, the Credit Limit is also capped by the amount of the financial Guaranty.

The BGS-FP Supplier will be granted a single Credit Limit to be applied to all BGS Supply agreements between the BGS-FP Supplier and the Companies. The BGS-FP Supplier will be required to post cash or a Letter of Credit for the Margin due each of the Companies as set forth in Section 6.6.

(b) If the BGS-FP Supplier chooses to rely upon a Guarantor to satisfy the requirements of this Section 6.4(i), the requirements of this subsection 6.4(i)(b) shall apply. If the BGS-FP Supplier has a Guarantor, the Guarantor (1) must be rated by at least two of the following rating agencies: S&P, ▇▇▇▇▇’▇ or Fitch, and (2) must have a minimum senior unsecured debt rating equal to the Minimum Rating. In the event that senior unsecured debt ratings are unavailable from S&P and Fitch, the corporate issuer rating, discounted one notch, will be used. In the event that senior unsecured debt ratings are unavailable from ▇▇▇▇▇’▇, the issuer rating will be used. The Companies will only rely on senior unsecured debt ratings, or if unavailable, issuer or corporate issuer ratings. If the Guarantor does not have a senior unsecured debt rating and does not have an issuer or corporate issuer rating from a rating agency, it will be deemed by the Companies not to be rated by that rating agency. If the Guarantor is rated by only two rating agencies, and the ratings are split, the lowest rating will be used. If the Guarantor is rated by three rating agencies, and the ratings are split, the lower of the two highest ratings will be used; provided, however, that in the event that the two highest ratings are common such

common rating will be used. The maximum level of the Credit Limit to cover the Total Exposure Amount that could be provided through the financial Guaranty will be determined in accordance with Table A.

The BGS-FP Supplier will be granted a Credit Limit equal to the lesser of: (i) the amount of the Guaranty provided to the Companies at the time this Agreement is executed as such amount may be modified in any amended or substitute Guaranty provided to the Companies during the Term or (ii) the Credit Limit applicable to the Guarantor’s credit rating in accordance with Table A. The BGS-FP Supplier, however, may not increase or substitute its Guaranty for the purpose of increasing its applicable Credit Limit during the time period after each of the Companies has made a Margin Call but before the BGS-FP Supplier has posted the required Margin. Notwithstanding anything herein to contrary, the BGS-FP Supplier may increase the limit of its Guaranty after satisfying a Margin Call from each of the Companies and upon each of the Companies’ receipt of an amended or substitute Guaranty increasing the limit of the Guaranty, the BGS-FP Supplier may request a return of Margin in accordance with Section 6.6(iii). The BGS-FP Supplier will be required to post cash or a Letter of Credit for the Margin due each of the Companies as set forth in Section 6.6.

(c) As an alternative to satisfying the requirements of subsections 6.4(i)(a) or 6.4(i)(b), the BGS-FP Supplier may post cash or a Letter of Credit for the entire Total Exposure Amount.

(ii) The following standards shall apply in the event that either the BGS-FP Supplier or its Guarantor has not been incorporated or otherwise formed under the laws of the United States. If the BGS-FP Supplier cannot meet the following requirements, the posting of cash or a Letter of Credit for the Total Exposure Amount will be required at the time of or prior to the execution of this Agreement.

(a) The BGS-FP Supplier shall supply such evidence of creditworthiness so as to provide the Companies with comparable assurances of creditworthiness as is applicable above for BGS-FP Suppliers that have been incorporated or otherwise formed under the laws of the United States; provided, however, that each of the Companies shall have sole and absolute discretion, without liability or recourse to the BGS-FP Supplier, to evaluate the evidence of creditworthiness submitted by the BGS-FP Supplier; or

(b) The BGS-FP Supplier’s Guarantor shall supply such evidence of creditworthiness so as to provide the Companies with comparable assurances of creditworthiness as is applicable above for Guarantors of BGS-FP Suppliers that have been incorporated or otherwise formed under the laws of the United States; provided, however, that each of the Companies shall have sole and absolute discretion, without liability or recourse to the Guarantor or the BGS-FP Supplier, to evaluate the evidence of creditworthiness submitted by such Guarantor.

(iii) If either the BGS-FP Supplier or its Guarantor has not been incorporated or otherwise formed under the laws of the United States, then either the BGS-FP Supplier or its Guarantor or both, as the case may be, in addition to all documentation required elsewhere in this Section 6.4, shall supply the following as a condition of being granted a Credit Limit.

(a) For the BGS-FP Supplier: (i) a legal opinion of independent counsel qualified to practice in the foreign jurisdiction in which the BGS-FP Supplier is incorporated or otherwise formed that this Agreement is, or upon the completion of execution formalities will become, the binding obligation of the BGS-FP Supplier in the jurisdiction in which it has been incorporated or otherwise formed; (ii) the sworn certificate of the corporate secretary (or similar officer) of the BGS-FP Supplier that the person executing the Agreement on behalf of the BGS-FP Supplier has the authority to execute the Agreement and that the governing board of the BGS-FP Supplier has approved the execution of the Agreement; and (iii) the sworn certificate of the corporate secretary (or similar officer) of the BGS-FP Supplier that the BGS-FP Supplier has been authorized by its governing board to enter into agreements of the same type as this Agreement. Each of the Companies shall have full discretion, without liability or recourse to the BGS-FP Supplier, to evaluate the sufficiency of the documents submitted by the BGS-FP Supplier.

(b) For the BGS-FP Supplier’s Guarantor: (i) a legal opinion of independent counsel qualified to practice in the foreign jurisdiction in the which the Guarantor is incorporated or otherwise formed that this Guaranty is, or upon the completion of execution formalities will become, the binding obligation of the

Guarantor in the jurisdiction in which it has been incorporated or otherwise formed; (ii) the sworn certificate of the corporate secretary (or similar officer) of such Guarantor that the person executing the Guaranty on behalf of the Guarantor has the authority to execute the Guaranty and that the governing board of such Guarantor has approved the execution of the Guaranty; and (iii) the sworn certificate of the corporate secretary (or similar officer) of such Guarantor that the Guarantor has been authorized by its governing board to enter into agreements of the same type as this Guaranty. Each of the Companies shall have sole and absolute discretion, without liability or recourse to the Guarantor or the BGS-FP Supplier, to evaluate the sufficiency of the documents submitted by such Guarantor.

6.5 Guaranty

A form of Guaranty is provided in Appendix F. The Guaranty, if relied upon by the BGS-FP Supplier, must be in the form of Appendix F, or in a substantially similar form approved by each of the Companies in advance of the Illinois Auction in accordance with the process announced on the Illinois Auction Website.

6.6 Posting Margin and Return of Surplus Margin

(i) If at any time during the Term, the Total Exposure Amount exceeds the BGS-FP Supplier’s Credit Limit, then each of the Companies, on any Business Day, may request that the BGS-FP Supplier provide Margin in the form of cash or a Letter of Credit (a “Margin Call”). The Margin requirement will be rounded up to the nearest $100,000.

(ii) If the BGS-FP Supplier receives written notice for Margin from each of the Companies by 1:00 p.m. EPT on a Business Day, then the BGS-FP Supplier shall post Margin the immediately following Business Day if posting cash, and the second Business Day if posting a Letter of Credit; provided, however, that one or more of the Companies may agree in writing to extend the period to provide Margin. If the BGS-FP Supplier receives notice for Margin from one or more of the Companies after 1:00 p.m. EPT on a Business Day, then the BGS-FP Supplier must post Margin the second Business Day following the date of notice unless each of the Companies agrees in writing to extend the period to provide Margin. None of the Companies will unreasonably deny a request for a one (1) Business Day extension of such period. In the event that the BGS-FP Supplier fails to provide Margin when due, then an Event of Default under Article 5 will be deemed to have occurred and each of the Companies will be entitled to the remedies set forth in Article 5.

(iii) Any cash or a Letter of Credit held by or for the benefit of one or more of the Companies in excess of the required Margin (“Surplus Margin”), as determined above, will be returned to the BGS-FP Supplier upon receipt of a written request by the BGS-FP Supplier. If the BGS-FP Supplier posted cash and notice is received by 1:00 p.m. EPT on a Business Day, the Surplus Margin will be returned by the immediately following Business Day. If the BGS-FP Supplier posted cash and notice is received by each of the Companies after 1:00 p.m. EPT on a Business Day, the Surplus Margin shall be returned by the second Business Day following the date of notice. If the BGS-FP Supplier posted a Letter of Credit to secure its Margin requirement, the Surplus Margin shall be returned on the next Business Day following the Business Day on which the BGS-FP Supplier’s written request for its return is received by each of the Companies. Each of the Companies may satisfy its obligation to return Surplus Margin included in a Letter of Credit posted by the BGS-FP Supplier by signing and transmitting by telecopy to the issuing bank a New Availability Certificate (as provided for in Annex 3 to the Letter of Credit) for the new Margin amount. In the event that one or more of the Companies fails to satisfy its obligation to return the Surplus Margin when due in accordance with this Article, then an Event of Default under Article 5 will be deemed to have occurred and the BGS-FP Supplier will be entitled to the remedies set forth in Article 5 unless the BGS-FP Supplier agrees in writing to extend such period for returning the Surplus Margin. The BGS-FP Supplier will not unreasonably deny a request for a one-business day extension of the period for returning the Surplus Margin.

6.7 Grant of Security Interest/Remedies

To secure its obligations under this Agreement and to the extent that the BGS-FP Supplier delivered Margin or collateral hereunder, the BGS-FP Supplier hereby grants to each of the Companies a present and continuing security interest in, and lien on (and right of setoff against), and assignment of, all cash collateral and cash equivalent collateral and any and all proceeds resulting therefrom or the liquidation thereof, whether now or hereafter held by, on behalf of, or for the benefit of, each of the Companies, and in all amounts owed to the BGS-FP Supplier by each of the Companies under or in connection with any BGS Supply agreement. The BGS-FP Supplier agrees to take such action as reasonably required to perfect in favor of each of the Companies a first priority security interest in, and lien on (and right of setoff against), such collateral and any and all proceeds resulting therefrom or from the liquidation thereof.

Upon or any time after the occurrence of an Event of Default caused by the BGS-FP Supplier, each of the Companies affected by such default may do any one or more of the following: (i) exercise any of the rights and remedies of such Company with respect to all collateral, including any such rights and remedies under law then in effect; (ii) exercise its rights of setoff against any and all property of the BGS-FP Supplier held by or for the benefit of such Company whether held in connection with this Agreement or any other agreement(s) between such Company and the BGS-FP Supplier for the provision of BGS Supply; (iii) draw on any outstanding letter of credit issued for the benefit of such Company; and (iv) liquidate all security held by or for the benefit of such Company free from any claim or right of any nature whatsoever of the BGS-FP Supplier, including any equity or right of purchase or redemption by the BGS-FP Supplier. The Company or Companies affected by such default shall apply the proceeds of the collateral realized upon the exercise of such rights or remedies to reduce the BGS-FP Supplier’s obligation under this Agreement or any other agreement(s) between such Company and the BGS-FP Supplier for the provision of BGS Supply (the BGS-FP Supplier remaining liable for any amounts owing to the Company after such application), subject to the Company’s obligation to return any surplus proceeds remaining after such obligations are satisfied in full.

All notices, demands or requests regarding credit requirements and credit related security or deposit transfers shall be in writing and shall be personally delivered or sent by overnight express mail, courier service or facsimile transmission (with the original transmitted by any of the other aforementioned delivery methods) addressed as follows:

If to the BGS-FP Supplier: Notification information for each BGS-FP Supplier is set forth on Appendix A hereto.

6.8 Security Instruments

6.8.a Provision of Security Instrument

At the BGS-FP Supplier’s choice, the following are deemed to be acceptable methods for posting security (each, a “Security Instrument”), if required:

(i) Cash; or

(ii) An irrevocable transferable standby letter of credit acceptable to each of the Companies issued by a bank or other financial institution with a minimum “A” senior unsecured debt rating from S&P or A2 from ▇▇▇▇▇’▇ (or, if unavailable, an issuer rating from ▇▇▇▇▇’▇ or a corporate issuer rating discounted one notch from S&P) (a “Letter of Credit”). (A standard format for the Letter of Credit is provided in Appendix E. Each of the Companies is willing to consider alternative forms of the Letter of Credit if they have been approved by each of the Companies in advance of the Illinois Auction in accordance with the process announced on the Illinois Auction Website.) The Letter of Credit shall state that it shall renew automatically for successive one-year or shorter periods unless one or more of the Companies receives written

notice from the issuing financial institution at least ninety (90) days, but not more than one hundred twenty (120) days, prior to the expiration date stated in the Letter of Credit that the issuing financial institution elects not to extend the Letter of Credit. If one or more of the Companies receives notice from the issuing financial institution that the Letter of Credit will not be extended, the BGS-FP Supplier will be required to provide a substitute Letter of Credit from an alternative bank satisfying the minimum requirements. The receipt of the substitute Letter of Credit must be effective as of the expiration date and delivered to each of the Companies at least thirty (30) days before the expiration date of the original Letter of Credit. If the BGS-FP Supplier fails to supply a substitute Letter of Credit as required herein, then each of the Companies will have the right to draw on the existing Letter of Credit and to hold the amount as Margin.

If the credit rating of a bank or other financial institution from which the BGS-FP Supplier has obtained a Letter of Credit falls below levels specified in this Article 6, the BGS-FP Supplier shall have two (2) Business Days following written notice by each of the Companies to obtain a suitable Letter of Credit from another bank or other financial institution that meets those standards unless such period is extended in writing by each of the Companies.

6.8.b BGS-FP Supplier Rights if one or more of the Companies is Rated Below Minimum Rating

If at any time during the Term, the applicable credit rating of one or more of the Companies is downgraded below the Minimum Rating, at the request of the BGS-FP Supplier, such Company or Companies will transfer within two (2) Business Days all cash collateral being held by it or them pursuant to this Agreement to a Qualified Institution. The Qualified Institution will hold the collateral in an interest-bearing account pending release of the funds pursuant to the terms of this Agreement with the title of such account indicating that the property contained therein is being held as collateral for the ownership of the posting Party, subject to the security interest of the other Party. Interest will be allocated pro rata to the BGS-FP Supplier. The BGS-FP Supplier will be entitled to the rights described in this Section 6.8.b only so long as the applicable rating for such Company or Companies is below the Minimum Rating.

6.9 Maintenance of Creditworthiness

6.9.a Reporting of Changes

The BGS-FP Supplier shall promptly notify each of the Companies of any change in its credit rating or the credit rating of its Guarantor, shall promptly notify each of the Companies if the BGS-FP Supplier or its Guarantor is placed on a credit watch with negative implications by any rating agency, and shall also notify each of the Companies of any materially adverse change in its financial condition or in the financial condition of its Guarantor. The BGS-FP Supplier or Guarantor shall also furnish evidence of an acceptable credit rating or financial condition upon the request of one or more of the Companies. Each of the Companies shall promptly notify the BGS-FP Supplier in the event that the applicable rating of any Company is downgraded below the Minimum Rating.

6.9.b Change in Credit Standing

The Companies will re-evaluate the creditworthiness of the BGS-FP Supplier whenever they become aware, through the provision of notice by the BGS-FP Supplier or otherwise, of a downgrade in the BGS-FP Supplier’s or Guarantor’s credit rating. If the lowest credit rating (whether issuer rating, corporate issuer rating or senior unsecured debt rating) used to determine the BGS-FP Supplier’s Credit Limit is downgraded, the Companies will immediately reassess the amount of the Credit Limit to be granted the BGS-FP Supplier pursuant to Section 6.4, as well as the adequacy of the Margin and the collateral being provided by the BGS-FP Supplier pursuant to Sections 6.6 and 6.8. If necessary, one or more of the Companies will request and the BGS-FP Supplier shall provide an additional Security Instrument to such Companies (or increase the value of the existing Security Instrument) in accordance with Sections 6.6 and 6.8.

6.10 Calling on Security

One or more of the Companies may call upon the Security Instrument posted by the BGS-FP Supplier if the BGS-FP Supplier fails to pay amounts due to such Company or Companies pursuant to this Agreement or any other agreement(s) between such Company or Companies and the BGS-FP Supplier for the provision of BGS Supply after all of the following events occur:

(i) Written Notice of Default is provided to the BGS-FP Supplier; and

(ii) Any applicable cure period ends.

The foregoing notwithstanding, the Security Instrument posted by the BGS-FP Supplier shall become due automatically, and may be called upon by one or more of the Companies, without prior notice or right of cure in the case of any Event of Default arising under Section 5.1 (i), (ii), (iii), (iv), (v), (vi), (vii), (viii) or (ix).

6.11 Interest on Cash Held by Companies

Each of the Companies will pay simple interest (not compounded) calculated at the lower of the Interest Index or six (6) percent per annum on all cash posted by the BGS-FP Supplier and directly held by or on behalf of each of the Companies pursuant to this Agreement. Each Billing Period, each of the Companies will prepare a statement of interest amounts due to the BGS-FP Supplier. The statement will be sent to the BGS-FP Supplier within three (3) Business Days after the end of the Billing Period via overnight mail, facsimile or other expeditious means. Each of the Companies shall make interest payments on the first Business Day after the fifth (5^th) day of each Billing Period.

6.12 Confidentiality

Information supplied by the BGS-FP Supplier in connection with the creditworthiness process shall be deemed confidential and not subject to public disclosure, unless Applicable Legal Authorities require disclosure of the information. If information must be disclosed, then the confidentiality of the information shall be maintained consistent with the Applicable Legal Authority’s rules and regulations pertaining to confidentiality. The BGS-FP Supplier will be given prompt notice of any request by a third party to obtain confidential information related to the BGS-FP Supplier’s creditworthiness.

6.13 No Endorsement of BGS-FP Supplier

The Companies’ determination that the BGS-FP Supplier is creditworthy pursuant to the process set forth above, shall not be deemed to constitute an express or implied warranty or guarantee of any kind with respect to the financial or operational qualifications of the BGS-FP Supplier. Each of the Companies will treat all BGS-FP Suppliers in a non-discriminatory manner and shall provide no preference to any BGS-FP Supplier.

6.14 Multiple BGS Supply Agreements

It is the intent of each of the Companies and the BGS-FP Supplier that, in the event the BGS-FP Supplier is a party to other agreements with a Company for the provision of BGS Supply, the Companies will calculate one (1) Margin applicable to all such agreements using the methodology set forth herein. The BGS-FP Supplier will have a single line of credit applicable to all BGS Supply agreements, and the Margin that is calculated is the Total Exposure Amount under all such contracts less the single line of credit.

ARTICLE 7. PROCEDURES FOR ENERGY SCHEDULING, CAPACITY

RESOURCE SUBMISSION, TRANSMISSION PROCUREMENT AND

ARR/FTR ALLOCATION

7.1 Generally

The Parties must adhere to any applicable operational requirements of the MISO necessary to protect the integrity of the MISO Transmission System and the transmission systems of interconnected control areas, and must satisfy any and all criteria of the MISO, SERC and NERC, when applicable. The BGS-FP Supplier also must adhere to any applicable operational requirements of each of the Companies necessary to protect the integrity of each of the Companies’ local distribution systems.

The BGS-FP Peak Load Share will be determined by each of the Companies based on the zonal peak load contributions utilized in the MISO determination of the zonal obligations for Capacity, adjusted for contributions associated with Customers served by Retail Electric Suppliers, BGS-LFP Customers, BGS-LRTP Customers and Wholesale Customers.

7.2 Load Obligations

Each of the Companies and the BGS-FP Supplier acknowledge that the BGS-FP Customers are within the respective Companies’ metered boundaries and that the BGS-FP Load must be divided into MISO obligations specific to the BGS-FP Supplier based on the BGS-FP Supplier Responsibility Share.

7.3 Data Transmission

7.3.a Energy

The procedures for transmitting load obligation data for the BGS-FP Supplier’s hourly Energy obligations shall be as set forth by the MISO.

7.3.b Resource Adequacy

The procedures for transmitting load obligation data for the BGS-FP Supplier’s Resource Adequacy Requirements shall be as set forth by the MISO.

7.3.c Capacity

The procedures for transmitting the BGS-FP Supplier Responsibility Share data to be used by the MISO to determine the BGS-FP Supplier’s Capacity obligations shall be as set forth by the MISO.

7.3.d ARRs/FTRs

The procedures for transmitting the data regarding the allocation of ARRs/FTRs to the BGS-FP Suppliers shall be as set forth by the MISO.

7.4 Energy Scheduling

The BGS-FP Supplier shall schedule Energy resources to meet its obligations with the MISO as provided for in the MISO Agreements. The Energy obligations for the BGS-FP Supplier will be determined based on the BGS-FP Supplier Responsibility Share. The total preliminary BGS-FP Energy obligation will be equal to the difference between the preliminary total Energy obligations for each of the Companies’ Service Territories reduced by the sum of (i) the preliminary wholesale load, (ii) the preliminary total Energy obligations of the Retail Electric Suppliers active in the Service Territories, and (iii) the preliminary total Energy obligations of the suppliers serving BGS-LFP Load and BGS-LRTP Load in the Service Territories.

7.5 ARR/FTR Allocation and Nomination

The process for allocating and nominating ARRs/FTRs is set forth in Section 2.1.b(vi).

ARTICLE 8. THE ENERGY SETTLEMENT/RECONCILIATION PROCESS

8.1 Energy Settlement by ▇▇▇▇

MISO will conduct the settlement process to reflect the BGS-FP Supplier’s actual Energy obligations in a supply/usage reconciliation process. The Energy obligations for the BGS-FP Supplier will be determined based on the BGS-FP Supplier Responsibility Share. The reconciled total BGS-FP Energy obligation will be equal to the difference between the reconciled total Energy obligations for the Service Territories reduced by the sum of (i) the wholesale load, (ii) the reconciled total Energy obligations of the Retail Electric Suppliers active in the Service Territories, and (iii) the reconciled total Energy obligations of the suppliers serving BGS-LFP Load and BGS-LRTP Load in the Service Territories. Any adjustments for billing and metering errors reported subsequent to the calculation of FPEA will be proportionally allocated by each of the Companies to the BGS-FP Suppliers.

8.2 Energy Settlement by the Companies

In the event that actual BGS-FP Customer consumption data is not available until after the MISO deadline for conducting the final settlement, each of the Companies will conduct the settlement process with the BGS-FP Supplier. Should the MISO impose penalties against a Company as a result of the BGS-FP Supplier’s transactions and/or failure to meet the MISO requirements, such penalties shall be passed through by each of the Companies to the BGS-FP Supplier as part of this settlement process. In addition, all other charges from MISO that are related to the provision of Capacity, Energy and Ancillary Services, including any billing adjustments, will be allocated to the BGS-FP Supplier in accordance with Appendix C.

ARTICLE 9. BILLING AND PAYMENT

9.1 Billing Period

Except as provided in this Section 9.1, a Billing Period shall be each calendar month during the Delivery Period. If at any time during the Delivery Period, the applicable rating of any Company is below the Minimum Rating, as determined in accordance with Section 6.4, (i) the Billing Period applicable to that Company shall be shortened to be each calendar half-month during the Delivery Period; (ii) a Statement will be prepared and sent to the BGS-FP Supplier

promptly at each half-month; and (iii) payment will be made on the first Business Day after the ninth (9^th) day after the end of each half-month period. Alternatively, each of the Companies whose applicable rating has fallen below the Minimum Rating and the BGS-FP Supplier may agree upon a schedule. The shortened Billing Period applicable to such Company or Companies shall be in effect only for so long as the applicable rating for that Company or Companies is below the Minimum Rating.

9.2 Payment Obligations

Each of the Companies shall pay all amounts due to the BGS-FP Supplier hereunder, and the BGS-FP Supplier shall pay all amounts due to each of the Companies hereunder, in accordance with the following provisions:

(i) Each Billing Period, each of the Companies will prepare a Statement of amounts due to either the BGS-FP Supplier or to each of the Companies.

(ii) The Statement shall include line items applicable to the Billing Period in question for, inter alia: (a) the quantity of Energy of BGS-FP Supply provided during the Billing Period, (b) the BGS-FP Supply Charge, (c) the Ancillary Services Costs, and (d) the MISO Invoice Reimbursement Amounts.

(a) The Statement shall also include: (i) a line item for the Intermediate Energy Adjustment Amount for any prior Billing Period for which all IPEA data has become available since the issuance of the prior Statement and (ii) a line item for the Final Energy Adjustment Amount for any prior Billing Period for which all FPEA data has become available since the issuance of the prior Statement.

(b) A negative Intermediate Energy Adjustment Amount or Final Energy Adjustment Amount shall serve as an offset against charges to be paid by each of the Companies to the BGS-FP Supplier.

(c) The Ancillary Services Costs and the MISO Invoice Reimbursement Amounts shall serve as offsets against charges to be paid by each of the Companies to the BGS-FP Supplier.

(d) The first Statement shall also include a line item for the entire amount of the Supplier Fee, which shall serve as an offset against charges to be paid by each of the Companies to the BGS-FP Supplier.

(iv) If the Statement shows a net amount owed by one or more of the Companies to the BGS-FP Supplier, the appropriate Company or Companies shall pay such amount, unless disputed, by the first Business Day after the 19^th day succeeding the Billing Period. If the Statement shows a net amount owed by the BGS-FP Supplier to one or more of the Companies, the BGS-FP Supplier shall pay such amount, unless disputed, by the first Business Day after the 19^th day succeeding the Billing Period.

(v) Payments shall be subject to adjustment for any arithmetic errors, computation errors, meter reading or usage estimation errors, or other errors, provided that the Party asserting the error provides notice to the other Party within one (1) year of the Termination Date.

(vi) All payments of funds shall be made by electronic transfer to a bank designated by the recipient of such funds.

(vii) If payment is made by a Party after the due date shown on the Statement, a late fee will be added to the unpaid balance until the entire Statement is paid. This late fee will be calculated at the prime rate commercial borrowers are charged by ▇.▇. ▇▇▇▇▇▇ ▇▇▇▇▇ or its successor.

ARTICLE 10. SYSTEM OPERATION

10.1 Disconnection and Curtailment by the Companies

Each of the Companies shall have the right, without incurring any liability to the BGS-FP Supplier, to disconnect (or otherwise curtail, interrupt or reduce deliveries from) the BGS-FP Supplier or to disconnect (or otherwise curtail, interrupt or reduce deliveries to) any Customer whenever the appropriate Company (or Companies) determines in the exercise of its (or their) good faith discretion, or when a Company is directed by the MISO, that such a disconnection, curtailment, interruption or reduction is necessary to facilitate construction, installation, maintenance, repair, replacement or inspection of any of a Company’s facilities; or due to any other reason affecting the safe and reliable operation of a Company’s or a Customer’s facilities, including Emergencies, forced outages or potential overloading of a Company’s transmission and/or distribution circuits, potential damage to any Customer’s facilities or any risk of injury to persons; provided, however, that nothing in this Section 10.1 shall modify or otherwise alter the rights and obligations provided under any existing FERC approved agreement between one or more of the Companies and the BGS-FP Supplier governing the provision of interconnection services. Each of the Companies shall have the right to implement the MISO load response programs and emergency energy programs.

10.2 Inadvertent Loss of Service to BGS-FP Customers

The Parties agree and acknowledge that service to BGS-FP Customers may be inadvertently lost due to storms, weather, accidents, breakage of equipment or other events beyond the reasonable control of any of the Companies affecting the transmission and distribution of one or more of the Companies. Neither Party will have any liability to the other Party for the occurrence of such events except for each of the Companies’ obligation to pursue steps for the resumption of the disrupted service as set forth in Section 10.3. In no event will an inadvertent loss of service affect a Party’s obligation to make any payments then due or becoming due with respect to performance rendered prior to such inadvertent loss of service.

10.3 Good Faith Efforts

Each of the Companies shall use good faith efforts to: (i) minimize any curtailment, interruption or reduction to the extent practicable under the circumstances; (ii) provide the BGS-FP Supplier with prior notification of any curtailment, interruption or reduction, to the extent practicable; and (iii) resume service as promptly as practicable.

10.4 MISO Requirements

Each Party acknowledges and agrees that it will be bound by all MISO operating instructions, policies and procedures as are currently set forth in the MISO Operating Manual, which are available through the Internet on the MISO Home Page (▇▇▇▇://▇▇▇.▇▇▇▇▇▇▇▇▇▇.▇▇▇), as may be revised from time to time, which are needed to maintain the integrity of the MISO system. Each Party acknowledges and agrees that it will cooperate with the other Parties so that such other Parties will be in compliance with all MISO Emergency Operations Procedures, which include, but are not limited to, those procedures pertaining to minimum and maximum generation Emergencies, and measures requiring involuntary Customer participation, such as supply voltage reduction or full interruption of Customer load by either manual or automatic means.

10.5 Compliance with Governmental Directives

Each Party also acknowledges and agrees that the other Party may need to act in response to governmental or civil authority directives which may affect BGS-FP Customer load. Each Party agrees to cooperate with the other Parties in order to comply with said directives.

ARTICLE 11. DISPUTE RESOLUTION

11.1 Informal Resolution of Disputes

Each of the Companies and the BGS-FP Supplier shall use good faith and reasonable commercial efforts to informally resolve all disputes arising out of the implementation of this Agreement within no more than thirty (30) days. The BGS-FP Supplier’s point of contact for all information, operations, and questions shall be the Companies’ Power Supply Acquisition Unit, or its successor organization, and the Illinois Auction Website. Any dispute between any of the Companies and the BGS-FP Supplier under this Agreement shall be referred to a designated senior representative of each of the Parties, who shall attempt to timely resolve the dispute. If such representatives can resolve the dispute, such resolution shall be reported in writing to and shall be binding upon the Parties. If such representatives cannot resolve the dispute within a period not to exceed thirty (30) days, as specified above, or a Party fails to appoint a representative within ten (10) days of written notice of the existence of a dispute, either Party may proceed as permitted by Section 11.2 of this Agreement.

11.2 Recourse to Agencies or Courts of Competent Jurisdiction

Nothing in this Agreement shall restrict the rights of either Party to file a complaint with the FERC under relevant provisions of the Federal Power Act (“FPA”), with the ICC under relevant provisions of the Applicable Legal Authorities, with an Illinois state court of competent jurisdiction, or with a federal court of competent jurisdiction situated in the State of Illinois. The Parties’ agreement hereunder is without prejudice to any Parties’ right to contest the subject matter jurisdiction of the agency or court to which a complaint is brought.

As this is a wholesale power transaction subject to FERC jurisdiction, absent the agreement of each of the Companies and the BGS-FP Supplier to a proposed change to this Agreement, the Parties agree that the standard of review for any change to this Agreement, whether proposed by a Party, a non-party, the ICC or FERC acting sua sponte, will be the

“public interest” standard of review set forth in United Gas Pipe Line Co. v. Mobile Gas Service Corp., 350 U.S. 332 (1956) and Federal Power Commission v. Sierra Pacific Power Co., 350 U.S. 348 (1956).

If a Party determines to file a lawsuit related to this Agreement in a court, such lawsuit may only be filed in an Illinois state court of competent jurisdiction or a federal court of competent jurisdiction situated in Illinois.

ARTICLE 12. REGULATORY AUTHORIZATIONS AND JURISDICTION

12.1 Compliance with Applicable Legal Authorities

Each of the Companies and the BGS-FP Supplier are subject to, and shall comply with, all existing or future applicable federal, state and local laws, all existing or future duly promulgated orders or other duly-authorized actions of the MISO or of Applicable Legal Authorities that relate to or affect performance under this Agreement. Compliance by the Company with any Renewable Energy Portfolio Standards enacted, approved, required or ordered by the Applicable Legal Authorities shall not be deemed a breach or violation of this Agreement or an Event of Default under Section 5.1.

12.2 FERC Jurisdictional Matters

The inclusion herein of descriptions of procedures or processes utilized by the MISO or otherwise subject to the jurisdiction of FERC is intended solely for informational purposes. If anything stated herein is found by the FERC to conflict with or be inconsistent with any provision of the FPA, or any rule, regulation, order or determination of the FERC under the FPA, or if any existing procedures or processes utilized by the MISO are duly modified, the applicable FERC rule, regulation, order, determination or modification shall control. To the extent required under any provision of the FPA, or any rule, regulation, order or determination of the FERC under the FPA, each of the Companies and/or BGS-FP Supplier if applicable, shall use reasonable commercial efforts to secure, from time to time, all appropriate orders, approvals and determinations from the FERC necessary to support this Agreement.

ARTICLE 13. LIMITATION OF LIABILITY

13.1 Limitations on Liability

Except to the extent expressly set forth in this Agreement, the BGS-FP Supplier shall be liable to each of the Companies, and vice versa, for direct damages incurred as a result of such Party’s failure to comply with this Agreement and no Party shall have any liability to the other Party for consequential, indirect, special or punitive damages, including lost profits or lost revenues, arising out of such Party’s failure to comply with its obligations under this Agreement. Notwithstanding anything to the contrary in this Agreement, this Agreement does not impose on the BGS-FP Supplier any obligation towards or liability to any Other BGS Supplier.

13.2 Risk of Loss and Changes in Market Rules and Conditions

Until the BGS-FP Supply is delivered to each of the Companies at the Delivery Points, the BGS-FP Supplier shall bear all risk of loss associated with the procurement and delivery of BGS-FP Supply. Title to and risk of loss related to BGS-FP Supply shall transfer from the BGS-FP Supplier to each of the Companies at the Delivery Points. The BGS-FP Supplier warrants that it will deliver to each of the Companies BGS-FP Supply free and clear of all liens, security interests, claims and encumbrances or any interest therein or thereto by any person arising prior to the Delivery Points.

Each of the Companies will bear the risk of any changes in the charges and requirements associated with delivery service and NITS. The BGS-FP Supplier will bear the risk of all other changes in market rules or conditions, whatever the cause or source of those changes, that result in the imposition of new, additional or increased charges, services or products being required in order to effect the delivery of BGS-FP Supply to the Delivery Points. Subject to the provisions of Section 15.13, should any such charges, services, responsibilities or products be imposed on or allocated to one or more of the Companies by any Applicable Legal Authority, the appropriate Company or Companies shall allocate or assign such charges, services, responsibilities or products to the BGS-FP Supplier, and the BGS-FP Supplier agrees to accept such allocation or assignment.

ARTICLE 14. INDEMNIFICATION

14.1 Indemnification

(i) Should one or more of the Companies become the defendant in, or obligor for, any third party’s claims and/or liabilities for losses, penalties, expenses, damage to property, injury to or death of any person including a Party’s employees or any third parties, including, without limitation, damages as provided in Section 16-125 of the Illinois Public Utilities Act and implementing rules, that were caused by or occur as a result of an act or omission of the BGS-FP Supplier with respect to performance of an obligation arising under this Agreement, or for which the BGS-FP Supplier has otherwise assumed liability under the terms of this Agreement, the BGS-FP Supplier shall defend (at each of the Companies’ option), indemnify and hold harmless each of the Companies, their shareholders, board members, directors, officers and employees and agents, from and against any and all such third party claims and/or liabilities, except to the extent that a court of competent jurisdiction determines that the losses, penalties, expenses or damages were caused wholly or in part by the gross negligence or willful misconduct of a Company.

Notice received after the close of the Business Day shall be deemed received on the next Business Day; provided, that notice by facsimile transmission shall be deemed to have been received by the recipient if the recipient confirms receipt telephonically or in writing.

15.2 No Prejudice of Rights

The failure of a Party to insist on any one or more instances upon strict performance of any provisions of this Agreement, or to take advantage of any of its rights hereunder, shall not be construed as a waiver of any such provisions or the relinquishment of any such right or any

other right hereunder, which shall remain in full force and effect. No term or condition of this Agreement shall be deemed to have been waived and no breach excused unless such waiver or consent to excuse is in writing and signed by the Party claimed to have waived or consented to excuse.

15.3 Assignment

Parties shall not assign any of their rights or obligations under this Agreement without obtaining (a) any necessary regulatory approval(s) and (b) the prior written consent of the non-assigning Party, which consent shall not be unreasonably withheld or delayed; provided, however, that each of the Companies agrees that it shall grant its consent to a proposed assignment by the BGS-FP Supplier if the proposed assignee meets all of the Companies’ creditworthiness requirements then in effect under Article 6. No assignment of this Agreement shall relieve the assigning Party of any of its obligations under this Agreement until such obligations have been assumed by the assignee and all necessary consents have been obtained. Any assignment in violation of this Section 15.3 shall be void; provided, however, a Company may assign any or all of its rights and obligations under this Agreement with prior written notice to the BGS-FP Supplier but without the BGS-FP Supplier’s consent, to any entity succeeding to all or substantially all of the assets of such Company, if such assignee agrees, in writing, to be bound by all of the terms and conditions and all necessary regulatory approvals are obtained. The BGS-FP Supplier may, with prior written notice to each of the Companies but without obtaining the approval of each of the Companies, assign the accounts, revenues or proceeds under this Agreement to a third party. Each of the Companies agrees that, following receipt of such notice of the assignment of accounts, revenues or proceeds and such other documentation that each of the Companies may reasonably request, each of the Companies will pay amounts becoming due to the BGS-FP Supplier under this Agreement directly to the designated assignee; provided, however, that nothing herein shall enlarge or expand the rights of such designated assignee beyond the rights granted to the BGS-FP Supplier and the right of such designated assignee to receive payments shall be subject to all defenses, offsets and claims of each of the Companies arising under this Agreement. Each of the Companies further agrees that, in the event necessary regulatory approvals to effectuate an assignment have been sought in good faith but that action by the regulatory body is pending, each of the Companies shall accept the performance of the proposed assignee as a Party to this Agreement, as co-obligor with the BGS-FP Supplier proposing to assign its interest, until such approvals are obtained; provided, however, that, in the event the regulatory body declines to grant its approval, the request for approval of the assignment shall be deemed to have been rejected for good reason.

15.4 Governing Law and Venue

APPENDIX D TO THE BGS-FP SUPPLIER FORWARD

CONTRACT

MTM EXPOSURE AMOUNT CALCULATION INFORMATION

Disclaimer: The prices that appear in this Appendix are purely hypothetical and are not based on or derived from any actual source for forward pricing. They are included solely for purposes of illustration.

As set forth in Articles 1 and 6 of this Agreement, the MtM Exposure Amount is an amount calculated each Business Day for the BGS-FP Supplier that reflects the financial exposure to each of the Companies due to fluctuations in market prices for Energy, less any amounts due to the BGS-FP Supplier pursuant to this Agreement for the delivery of BGS-FP Supply.

This Appendix D explains the methodology and data sources that each of the Companies will use to calculate the MtM. MtM refers to the Companies’ financial exposure due to fluctuations in market prices for Energy, while MtM Exposure Amount refers to the financial exposure net of any amount due to the BGS-FP Supplier for BGS-FP Supply already delivered.

If the sum of the MtM Exposure Amounts for all agreements for BGS-FP Supply executed in 2006 between any of the Companies and the BGS-FP Supplier results in a negative number, the MtM Exposure Amount shall be zero.

MTM

The MtM will be calculated for each month of deliveries under this Agreement. The MtM is calculated as the sum of i) changes in On-Peak Forward Market Prices (relative to On-Peak Forward Market Prices on the closing day of the Illinois Auction) multiplied by the on-peak MWh volume assumptions for BGS-FP Load; and ii) changes in estimated Off-Peak Forward Market Prices (relative to estimated Off-Peak Forward Market Prices on the closing day of the Illinois Auction) multiplied by the off-peak MWh volume assumptions for BGS-FP Load. The total MtM that will be used to calculate the MtM Exposure Amount will be equal to the sum of the MtM for each remaining month in the Delivery Period times 1.1. When On-Peak Forward Market Prices are not available for a given month, an estimate of that month’s On-Peak Forward Market Price will be used to establish the MtM.

Change in On-Peak Forward Market Price

On each Business Day during the term of this Agreement, each of the Companies will calculate the change in On-Peak Forward Market Price for each month to be the difference between that day’s “Mark” (the current On-Peak Forward Market Price for that month) and the “Initial Mark” (the On-Peak Forward Market Price for that month as of the closing day of the Illinois Auction.) Initial Marks determined at the close of the Illinois Auction are provided in Table 1. These values are fixed for the term of this Agreement.

Change in Off-Peak Forward Market Price

On each Business Day during the term of this Agreement, each of the Companies will calculate the change in Off-Peak Forward Market Price to be the change in On-Peak Forward Market Price for that month multiplied by the historical off-peak to on-peak price ratio for that month.

The historical off-peak to on-peak price ratios that will be used to calculate the MtM are provided in Table 2. These values are fixed for the term of this Agreement.

D-1

Estimated Energy Quantities

On-peak and off-peak energy assumptions used to calculate the MtM are provided in Table 3. These values may be adjusted (but no more frequently than monthly) to reflect the most current changes in BGS-FP energy assumptions.

PRICING SOURCES FOR INITIAL MARKS AND MARKS

Quotes for Standard Power Products in the Over-The-Counter Broker Market

The Companies (or an agent for the Companies) will communicate with at least two and up to four Brokers who actively broker forward power products. The Companies or their agent will obtain bid and ask quotes for forward on-peak (5x16) energy products at the MISO Illinois Hub for each remaining month of the Delivery Period. The Companies may also rely on quotes for standard forward power products at other relevant power trading hubs if it deems there is insufficient liquidity at the MISO Illinois Hub. To the degree other hubs are relied on, an appropriate “basis” may be calculated and applied to reflect locational price differences in the spot and/or forward markets.

Alternative Sources of Price Data

In addition to Broker quotes, the Companies may also rely on alternative sources of price data, should Broker data be insufficient, such as a Published Index or prices for exchange-traded electricity futures contracts.

Definition of an Available Broker Quote

For Broker quotes, both a bid and ask price must be quoted from at least two Brokers for

the price to be deemed available.

METHODOLOGY FOR SETTING INITIAL MARKS AND MARKS

Setting the Initial Mark for the On-Peak Forward Market Price

For the months for which the Companies or their agent can obtain Available Broker Quotes, the on-peak Initial Mark will equal the simple average of the bid and ask prices for those months where quotes are available. These “mid-market” prices will further be averaged across Brokers in order to set the Initial Mark. For a given month, the Available Broker Quotes used may be quoted specific to that month or for a multi-month block period containing the given month. If the Companies obtain multiple Available Broker Quotes that contain a given month, the Available Broker Quote for the shortest available period will be used to calculate the Available Broker Quote used to set the Mark for the given month. Thus, if the Companies or their agent are unable to obtain an Available Quote specific to that month, but can “back out” a monthly quote proxy using multi-month block Available Broker Quotes, the “backed out” price method will be utilized.

If the Companies or their agent cannot obtain Available Broker Quotes for certain months, alternative sources of price data will be relied on for setting the Initial Mark for the On-Peak Forward Market Price, to the extent such pricing data is available from the alternative sources.

For months for which Available Broker Quotes cannot be obtained and pricing information is unavailable from alternative sources, each of the Companies will set the on-peak Initial Mark using a methodology that utilizes the best information available to each of the Companies at that time. The Companies will further develop this methodology in consultation with ICC Staff and the Auction Manager, in advance of the Illinois Auction.

Indicative pricing for the Initial Marks utilizing the methodology elaborated above will be provided to the BGS-FP Suppliers at least 14 days prior to the Illinois Auction, and will be updated on each Business Day during the Illinois Auction. ICC Staff will be provided with the indicative pricing for the Initial Marks prior to its release.

D-2

Setting the Initial Mark for the Off-Peak Forward Market Price

The Initial Mark for the Off-Peak Forward Market Price will be the Initial Mark for the On-Peak Forward Market Price multiplied by the off-peak to on-peak price ratio for the month from Table 2.

Updating the Mark for the On-Peak Forward Market Price

Each Business Day during the term of this Agreement, each of the Companies will calculate the Mark for On-Peak Forward Market Prices based on the following methodology:

•

For each month, if the Companies or their agent are able to obtain Available Broker Quotes (as defined above), each of the Companies will include such quotes in the calculation of the MtM. For a given month, the Available Broker Quotes used may be quoted specific to that month or for a multi-month block period containing the given month. If the Companies obtain multiple Available Broker Quotes that contain a given month, the Available Broker Quote for the shortest available period will be used to calculate the Available Broker Quote used to set the Mark for the given month. Thus, if the Companies or their agent are unable to obtain an Available Quote specific to that month, but can “back out” a monthly quote proxy using multi-month block Available Broker Quotes, the “backed out” price method will be utilized.

•

If, on a given Business Day, the Companies or their agent are not able to obtain Available Broker Quotes, the Companies will look to alternative sources of price data and will rely on the prices from alternative data sources to update the Mark for the On-Peak Forward Price, if pricing data is available from the alternative sources.

•

If Broker quotes for a given month are not available on a given Business Day (the “Current Business Day”) and pricing data is unavailable from alternative sources for that month, the On-Peak Forward Market Prices for that month will be updated based on the change in On-Peak Forward Market Prices between the prior Business Day and the Current Business Day for those same months in different years during the Delivery Period for which quotes are available for the Current Business Day.

•

If, on a given Business Day, the Company or its agent is not able to obtain an Available Broker Quote for a given calendar month of any year during the Delivery Period, and pricing data from alternative sources for the given calendar month for any year during the Delivery Period is also unavailable, then each of the Companies will set the On-Peak Forward Market Price using a methodology that utilizes the best information available to each of the Companies at that time.

Updating the Mark for the Off-Peak Forward Market Price

As noted above, on each Business Day during the term of this Agreement, the Mark for the Off-Peak Forward Market Price for a given month will be equal to the Mark for the On-Peak Forward Market Price for that month multiplied by the historical off-peak to on-peak price ratio for that month from Table 2.

TIMING OF CALCULATIONS

Illustrative values for Tables 1, 2 and 3 will be provided 14 days prior to the Illinois Auction.

D-3

On the closing day of the Illinois Auction, the following parameters will be set:

1. A table of on-peak Initial Marks for each month

2. A table of monthly historical off-peak/on-peak price ratios

3. On-peak energy quantity assumptions *

4. Off-peak energy quantity assumptions *

On each Business Day subsequent to the closing day of the Illinois Auction, the following

parameters will be set:

1. On-Peak Forward Market Prices

2. Change in On-Peak Forward Market Prices

3. Change in Off-Peak Forward Market Prices

Each month, the following parameters may, at each of the Companies’ discretion, be updated:

1. On-peak energy quantity assumptions *

2. Off-peak energy quantity assumptions *

*	Please note that the assumed energy values in this table are only intended for use in the calculation of the MtM Exposure Amount.

Subject to the terms and conditions hereof, this Guaranty is a continuing one and all liabilities to which it applies or may apply under the terms hereof shall be conclusively presumed to have been created in reliance hereon. Except for a failure to comply with any applicable statute of limitations, no failure or delay on the part of the Guaranteed Parties in exercising any right, power or privilege hereunder, and no course of dealing between the Guarantor and a Guaranteed Party, shall operate as a waiver thereof; nor shall any single or partial exercise of any right, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights, powers and remedies herein expressly provided are cumulative and not exclusive of any rights, powers or remedies, which a Guaranteed Party would otherwise have. No notice to or demand on the Guarantor in any case shall entitle the Guarantor to any other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of a Guaranteed Party to any other or further action in any circumstances without notice or demand.

8. This Guaranty shall be binding upon the Guarantor and upon its successors and assigns and shall inure to the benefit of and be enforceable by the Guaranteed Parties and their successors and assigns; provided, however, that the Guarantor may not assign or transfer any of its rights or obligations hereunder without the prior written consent of the Guaranteed Parties. The assignment rights of the Guaranteed Parties will be in accordance with any applicable terms of the Agreement(s).

9. Neither this Guaranty nor any provision hereof may be changed, waived, discharged or terminated except upon written agreement of the Guaranteed Parties and the Guarantor.

10. The Guarantor’s liability as guarantor shall continue and remain in full force and effect in the event that all or any part of any payment made hereunder or any obligation or liability guaranteed hereunder is recovered (as a fraudulent conveyance, preference or otherwise) rescinded or must otherwise be reinstated or returned due to bankruptcy or insolvency laws or otherwise. If claim is ever made upon the Guaranteed Parties for repayment or recovery of any amount or amounts received from the Guarantor or the BGS-FP Supplier in payment or on account of any of the Guaranteed Obligations and the Guaranteed Parties repay all or part of such amount by reason of (a) any judgment, decree or order of any court or administrative body having jurisdiction over such payee or any of its property, or (b) any settlement or compromise of any such claim effected by such payee with any such claimant (including the Guarantor), then and in such event the Guarantor agrees that any such judgment, decree, order, settlement or compromise shall be binding upon it, notwithstanding any revocation hereof or the cancellation of the Agreement(s) or other instrument evidencing any liability of the Guarantor, and the Guarantor shall be and remain liable to the Guaranteed Parties hereunder for the amount so repaid or recovered to the same extent as if such amount had never originally been received by the Guaranteed Parties.

11. Subject to Paragraph 10, this Guaranty shall remain in full force and effect until all Guaranteed Obligations have been fully and finally performed, at which point it will expire. The Guarantor may terminate this Guaranty upon thirty (30) days prior written notice to the Guaranteed Parties which termination shall be effective only upon receipt by the Guaranteed Parties of alternative means of security or credit support, as specified in the Agreement(s) and in a form reasonably acceptable to the

F-5

Guaranteed Parties. Upon the effectiveness of any such expiration or termination, the Guarantor shall have no further liability under this Guaranty, except with respect to the Guaranteed Obligations arising or created prior to the time the expiration or termination is effective, which Guaranteed Obligations shall remain guaranteed pursuant to the terms of this Guaranty until finally and fully performed.

12. All notices and other communications hereunder shall be made at the addresses by hand delivery, by the next day delivery service effective upon receipt, or by certified mail return receipt requested (effective upon scheduled weekday delivery day) or telefacsimile (effective upon receipt of evidence, including telefacsimile evidence, that telefacsimile was received)

14. This Guaranty and the rights and obligations of the BGS-FP Supplier and the Guarantor hereunder shall be construed in accordance with and governed by the laws of the State of Illinois. The Guarantor and Guaranteed Parties jointly and severally agree and irrevocably submit to the exclusive jurisdiction of state and federal courts located in the State of Illinois over any disputes arising or relating to this Guaranty and waive and agree not to assert as a defense any objections to venue or inconvenient forum. The Guarantor and the Guaranteed Parties consent to and grant any such court jurisdiction over the person of such party and over the subject matter of such dispute and agree that summons or other legal process in connection with any such action or proceeding shall be deemed properly and effectively served when sent by certified U.S. mail, return receipt requested, to the address of the other party set forth in Paragraph 12 hereof, or in such other manner as may be permitted by law. The Guarantor and the Guaranteed Parties each hereby irrevocably waives any and all rights to trial by jury with respect to any legal proceeding arising out of or relating to this Guaranty.

15. This writing is the complete and exclusive statement of the terms of this Guaranty and supersedes all prior oral or written representations, understandings, and agreements between the Guaranteed Parties and the Guarantor with respect to subject matter hereof. The Guaranteed Parties and the Guarantor agree that there are no conditions to the full effectiveness of this Guaranty.

16. Every provision of this Guaranty is intended to be severable. If any term or provision hereof is declared to be illegal or invalid for any reason whatsoever by a court of competent jurisdiction, such illegality or invalidity shall not affect the balance of the terms and provisions hereof, which terms and provisions shall remain binding and enforceable.

F-7

17. If the Guarantor is a trust: no trustee of the Guarantor shall be held to any liability whatsoever for any obligation under this Guaranty, and this Guaranty shall not be enforceable against any such trustee in their or its, his or her individual capacities or capacity; and this Guaranty shall be enforceable against the trustees of the Guarantor only as such, and every person, firm, association, trust or corporation having any claim or demand arising under this Guaranty and relating to the Guarantor or any trustee of the Guarantor shall look solely to the trust estate of the Guarantor for the payment or satisfaction thereof.

IN WITNESS WHEREOF, the Guarantor has caused this Guaranty to be executed and delivered as of the date first written above to be effective as of the earliest effective date of any of the Agreement(s).
