of KGLLC and the indirect sole owner of Seller. 

        E.    KGen
Power has issued 100% of its common stock in a private placement to a broad base of investors (the "Equity Offering"), the proceeds of which will be used to purchase
the member interests of KGLLC and to repay a portion of its consolidated indebtedness. At no time will KGen Power be an affiliate of Matlin Patterson Global Opportunities Partners II L.P. 

        F.     KGen
Power will have substantially the same management team as KGLLC prior to the foregoing transactions. 

        G.    The
Seller requests that GPC consent to the Change of Control Transaction that will occur as a result of the foregoing transactions. 

        H.    The
parties hereto now desire to enter into this Agreement to evidence certain consents, subject to the satisfaction of conditions set forth in Section 2.1. 

        NOW,
THEREFORE, in consideration of the foregoing premises and the representations, warranties, and covenants contained herein, the parties hereto agree as follows: 

ARTICLE 1

CONSENT  

        Section 1.1.    Consent.    Notwithstanding anything to the contrary contained in the PPA, including, without
limitation, Sections 19.1, 19.2 and 19.3 thereof, subject to the satisfaction of the conditions set forth in Section 2.1 below, GPC hereby consents to (a) the Change of Control
Transaction resulting from (i) the acquisition of the membership interest of KGLLC as contemplated by the PSA and (ii) the Equity Offering by KGen Power; and (b) the collateral
assignment of Seller's interest in the PPA to a collateral agent for the benefit of the lenders providing financing to KGen Power, Seller and the other secured parties described therein (and, with
respect to such collateral assignment, GPC hereby agrees to execute and deliver a consent in favor of such collateral agent substantially in the form of the

replacement Eligible Collateral for the Seller Performance Security in accordance with the terms of the PPA. Upon receipt of such replacement Eligible Collateral, GPC will release the existing

        (a)   the
closing of the transactions contemplated by the PSA and the Equity Offering (the "Effective Date"); 

        (b)   the
occurrence both before and after giving effect to such transactions on the Effective Date of no fact or circumstance arising under the PSA or with respect to the

        (c)   GPC's
receipt (which shall be deemed to include, without limitation, public notice of such written order) from the Georgia Public Service Commission of a written order
approving without condition (or, if conditional, only with such conditions that are reasonably acceptable to GPC) the transactions described herein as they relate to the PPA, unless the Georgia Public
Service Commission decides that such order is not necessary (in which case this clause (c) shall not be a condition precedent under this Section 2.1). For purposes of this
Section 2.1 (c), such order shall be deemed to be reasonably acceptable to GPC upon the earlier to occur of (i) GPC providing written notice of such acceptance by GPC and (ii) the
5th Business Day after GPC's receipt of such order, unless in the case of this clause (ii) GPC has notified Seller in writing on or prior to such 5th Business Day that such order is not
reasonably acceptable to GPC.

validly organized under the laws of its jurisdiction and has full corporate or limited liability company power, as

remains in full force and effect as originally written. 

        Section 2.4.    Governing Law.    This Agreement shall be governed by and construed in accordance with the laws
of the State of Georgia. 

        Section 2.5.    Counterparts.    This Agreement may be executed in several counterparts, each of which shall be
an original and all of which shall constitute a single instrument. 

        Section 2.6.    Amendments.    No waiver, amendment or other modification to the terms of this Agreement shall
be valid unless in writing and signed by the parties hereto.
