to which each Subsidiary Guarantor unconditionally guarantees the obligations of Holdings under the Indenture and the Bonds.

pursuant to the Bills of Sale and Participation Agreements, and in partial consideration for the sale of the Facilities, each Owner Lessor agreed to expressly assume, on a
several basis, a pro rata portion of all the obligations of EME Homer City under the Indenture and the related Bonds.

WHEREAS,
Homer City Funding desires to expressly assume, on behalf of each Owner Lessor, all obligations of EME Homer City under the Indenture and the Bonds in consideration for

NOW
THEREFORE, for and in consideration of the premises and the mutual promises and covenants set forth herein:
