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.
