Attention: Mr. Martin Wilson

TVA and Armstrong Coal Company, Inc. (“Armstrong”) are currently engaged in reopener negotiations with respect to TVA Contract No. 612-40668 (the “Contract”). Under Section 1.0 of the Contract, as amended by Section 1.0 (B) of Supplement No. 7, since the reopener provision has been exercised, the Contract will terminate on December 31, 2012, “unless TVA and Contractor have mutually agreed in writing no later than July 1, 2012, to continue this Contract.” The effective date of this Supplement is June 19, 2012.

The parties hereby agree to extend, from July 1, 2012, until August 1, 2012, the negotiation period within which the parties may reach mutual written agreement with respect to the current reopener.

To effect their agreement regarding the one-month extension of the current reopener negotiation period until August 1, 2012, the Contract is hereby modified as follows:

The following “Current Sentence” of Section 1.0 (B) is hereby deleted in its entirety and replaced with the following new “Replacement Sentence.”


Current Sentence:		If this negotiation provision has been exercised, this Contract will terminate on December 31, 2012, unless TVA and Contractor have mutually agreed in writing no later than July 1, 2012, to continue this Contract.

Replacement Sentence:		If this negotiation provision has been exercised, this Contract will terminate on December 31, 2012, unless TVA and Contractor have mutually agreed in writing no later than August 1, 2012, to continue this Contract.

The provisions of this Supplement No. 17 will apply to and only to the current reopener negotiations. It is the intention of the parties that Section 1.0 of the Contract, as amended by Section 1.0 (B) of Supplement No. 17, shall otherwise remain in full force in effect and that the “Current Sentence” quoted above, shall continue to apply without any modification to any reopener period or negotiations other than the current reopener period and negotiations.
