WITNESSETH:

WHEREAS, Beneficiary and Elwood Expansion Holdings, LLC, a Delaware limited liability company, Elwood Energy Holdings, LLC, a Delaware limited liability company, Tomcat Power, LLC, a Delaware limited liability company and Elwood Energy Holdings II, LLC, a Delaware limited liability company (together, “Sellers”), are parties to that certain Membership Interest Purchase Agreement dated as of the date hereof (the “MIPA”), for the sale by Sellers of the Transferred Interests (as defined in the MIPA);

WHEREAS, subject to the terms and conditions set forth herein, in order to induce Beneficiary to enter into the MIPA, Guarantor desires to guarantee the payment and performance obligations of Sellers set forth in the MIPA.

NOW, THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Guarantor agrees as follows:

DEFINITIONS; RULES OF INTERPRETATION

Section 1.1                                   Definitions.  Capitalized terms used herein and not otherwise defined shall have the meanings given in the MIPA.

Section 1.2                                   Rules of Interpretation.  The rules of interpretation set forth in Section 1.02 of the MIPA shall apply, mutatis mutandis, to this Guaranty.

ARTICLE 2
GUARANTY

Section 2.1                                   Guaranty.  For value received, Guarantor hereby absolutely, unconditionally and irrevocably guarantees to Beneficiary, as primary obligor and not as surety, the prompt payment and performance of all obligations, now or hereafter existing, of Sellers (including, without limitation, any assignee permitted thereunder) under the MIPA, including, without limitation, the payment of any amounts due pursuant to Section 8.01 of the MIPA to Beneficiary or other Indemnified Purchaser Entity (together with any and all costs and expenses, including reasonable counsel fees and expenses, incurred by Beneficiary in enforcing its rights under this Guaranty, the “Guarantied Obligations”) whether according to the present terms of the

MIPA or pursuant to any change in the terms, covenants or conditions of the MIPA at any time after the date hereof made or granted, including, without limitation, pursuant to any amendments, or waivers affecting the MIPA and the transactions contemplated by the MIPA.  In the event that Sellers fail in any manner whatsoever to pay or perform any of the Guarantied Obligations when due, Guarantor will itself duly and promptly pay and perform the Guarantied Obligations, or cause the Guarantied Obligations to be duly and promptly paid and performed, in each case as if Guarantor were itself Sellers with respect to the Guarantied Obligations.  This Guaranty shall remain in full force and effect from the date hereof until payment and performance in full of the Guarantied Obligations.

Section 2.2                                   Nature of Guaranty.  This Guaranty constitutes a Guaranty of payment and performance when due and not of collection, and Guarantor specifically agrees that it shall not be necessary or required that Beneficiary exercise any right, assert any claim or demand or enforce any remedy whatsoever against Sellers either before or as a condition to the obligations of Guarantor hereunder; provided, that Guarantor shall have the benefit of and the right to assert any defenses against the claims of Beneficiary that are available to Sellers, and that would have also been available to Guarantor if Guarantor had been in the same contractual position as Sellers under the MIPA other than (a) defenses arising from the insolvency, reorganization or bankruptcy of Sellers, (b) defenses expressly waived in this Guaranty, and (c) defenses previously asserted by Sellers against such claims to the extent such defenses have been finally resolved in Beneficiary’s favor by a court of last resort.  For the avoidance of doubt, payment or performance by Guarantor under the MIPA shall be due hereunder when and if such payment or performance is due (and in the case of a payment, payable) by Sellers (by acceleration or otherwise) to Beneficiary or other Indemnified Purchaser Entity under Article 8 of the MIPA.  All sums payable by Guarantor hereunder shall be paid by wire transfer of immediately available funds to an account designated by Beneficiary.

Section 2.3                                   Unconditional Obligations.  The obligations of Guarantor under this Guaranty are independent of the Guarantied Obligations and any obligations of Sellers under the MIPA, and an action may be brought and prosecuted against Guarantor to enforce this Guaranty, irrespective of whether any action is brought against Sellers, or whether Sellers are joined in any such action or actions.  The liability of Guarantor under this Guaranty shall be irrevocable, absolute and unconditional irrespective of, and Guarantor hereby irrevocably waives, any circumstance that constitutes a legal or equitable discharge under applicable Law of a guarantor or surety other than satisfaction in full of the Guarantied Obligations including, for the avoidance of doubt, (i) the validity, legality or enforceability of the MIPA or any agreement or document in connection with the MIPA, any of the Guarantied Obligations or any collateral security therefor or guarantee or right of offset with respect thereto at any time or from time to time held by Sellers, (ii) any claim, set-off, counterclaim or other right which may at any time be available to or be asserted by Sellers or Guarantor against Beneficiary or any of its Affiliates in connection with the Guarantied Obligations or otherwise, (iii) any requirement that Beneficiary exhaust any right to take any action against Sellers or any other Person prior to or contemporaneously with proceeding to exercise any right against Guarantor under this Guaranty, (iv) any change in the applicable Law of any jurisdiction, or (v) any present or future action of any Governmental Entity amending, varying, reducing or otherwise affecting or purporting to amend, vary, reduce or otherwise affect, any of the obligations of Sellers under the MIPA or of Guarantor under this

Guaranty, and Guarantor hereby waives any defense based on or arising out of any of the foregoing clauses (i) through (v).

Without limiting the generality of the foregoing, Guarantor hereby agrees, acknowledges and represents and warrants to Beneficiary as follows:

(a)         Guarantor hereby waives any defense arising by reason of, and any and all right to assert against Beneficiary any claim or defense based on, an election of remedies by Beneficiary which in any manner impairs, affects, reduces, releases, destroys and/or extinguishes Guarantor’s rights to proceed against Sellers or any other guarantor for reimbursement, indemnification or contribution, and/or any other rights of Guarantor to proceed against Sellers, any other guarantor, or any other Person or security.

(b)         Guarantor has independently reviewed the MIPA and has made an independent determination as to the validity and enforceability thereof, and in executing and delivering this Guaranty to Beneficiary, Guarantor is not in any manner relying upon the validity, and/or enforceability, and/or attachment, and/or perfection of any Liens of any kind or nature granted by Sellers to Beneficiary, now or at any time and from time to time in the future.

Section 2.4                                   Waiver.  Guarantor hereby unconditionally waives promptness, presentment, demand of payment, protest for nonpayment or dishonor, diligence, notice of acceptance and any other notice with respect to any of the Guarantied Obligations by Beneficiary, and all defenses not otherwise available to Sellers under the MIPA which may be available to Guarantor by virtue of any valuation, stay, moratorium law or other similar law now or hereafter in effect and any right to require the marshalling of assets of Sellers or any other Person interested in the transactions contemplated by the MIPA.  The Guarantied Obligations, and any of them, shall conclusively be deemed to have been created, contracted or incurred in reliance upon this Guaranty and all dealings between Sellers or Guarantor, on the one hand, and Beneficiary, on the other hand, shall likewise be conclusively presumed to have been had or consummated in reliance upon this Guaranty.  Guarantor hereby waives any defense based on (a) lack of authority of Sellers to enter into the MIPA or perform their obligations thereunder, (b) the failure of Sellers or any of their Affiliates to assert any claim or demand or to enforce any right or remedy under the provisions of the MIPA or any agreement or other document in connection with the MIPA or the transactions contemplated thereby, (c) any rescission, waiver, amendment or modification of any of the terms or provisions of the MIPA or any agreement or other document in connection with the MIPA (including, without limitation, any change in the time, place or manner of payment or performance of the Guarantied Obligations), (d) any insolvency, bankruptcy, reorganization, assignment for the benefit of creditors, liquidation, dissolution, or similar proceedings with respect to Sellers, (e) the release of, or any impairment of or failure to protect, secure, perfect or insure any Lien at any time held by Sellers at any time for the payment of the Guarantied Obligations, (f) any default, failure or delay, willful or otherwise, in the performance of the Guarantied Obligations, (g) the sale, exchange, waiver, surrender, substitution or release of any collateral security, guarantee or right of offset at any time held by Sellers for the payment of the Guarantied Obligations, (h) the adequacy of any other means Beneficiary may have of obtaining payment and performance of the Guarantied Obligations, (i) change of name, purpose, structure, organizational documents or ownership of Sellers and (j) any

change in the financial condition of Guarantor or Sellers.  Without limitation, Beneficiary may at any time and from time to time without notice to or consent of Guarantor and without impeding or releasing the obligations of Guarantor hereunder: (i) make any change to the terms of the Guarantied Obligations, including granting extensions, renewals, release or discharges of Sellers; (ii) take or fail to take any action of any kind in respect of any security for the Guarantied Obligations; (iii) exercise or refrain from exercising any rights against Sellers in respect of the Guarantied Obligations; (iv) compromise or subordinate the Guarantied Obligations, including any security therefore or accept settlement from Sellers; or (v) apply any sums received to any indebtedness for which Sellers are liable, whether or not such indebtedness is a Guarantied Obligation.

Section 2.5                                   No Subrogation.  Notwithstanding any payment or payments made by Guarantor under this Guaranty or any set-off or application of funds of Guarantor by Beneficiary, Guarantor shall not be entitled to be subrogated to any of the rights of Beneficiary against Sellers or any collateral security or Guaranty or right of offset held by Beneficiary for the payment of the Guarantied Obligations, nor shall Guarantor seek or be entitled to seek any contribution or reimbursement from Beneficiary in respect of payments made by Guarantor under this Guaranty.

Section 2.6                                   Representations and Warranties.  Guarantor hereby represents and warrants that:

(a)                                 it is a corporation duly organized and validly existing under the laws of Delaware;

Section 2.7                                   Termination.  If the MIPA is terminated prior to the Closing, this Guaranty shall terminate and be of no further force or effect.  Subject to Section 2.3, this Guaranty shall terminate and be of no further force or effect with respect to the Guarantied Obligations on the
