<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">As previously reported, on March&nbsp;14, 2013, Ameren entered into a transaction agreement (the &#147;AER Transaction Agreement&#148;) to
divest its wholly owned subsidiary, Ameren Energy Resources Company (&#147;AER&#148;), to Illinois Power Holdings, LLC (&#147;IPH&#148;), an indirect wholly owned subsidiary of Dynegy, Inc. Prior to entry into the AER Transaction Agreement,
(i)&nbsp;the original put option agreement, dated March&nbsp;28, 2012, between Genco and Ameren Energy Resources Generation Company (&#147;AERG&#148;) was novated and amended such that the rights and obligations of AERG under the agreement were
assigned to and assumed by Medina Valley and (ii)&nbsp;Genco exercised its option under the amended put option agreement to sell the Put Option Assets to Medina Valley. </P>

2013 (the &#147;Asset Purchase Agreement&#148;) and Genco received an initial payment of $100 million (the &#147;Initial Payment&#148;) for the Put Option Assets. The Asset Purchase Agreement provided that Genco would receive an additional payment
upon closing of the Asset Purchase Agreement to the extent the average of the fair market value for the Put Option Assets, as determined by three independent appraisals, exceeded the Initial Payment. Genco and Medina Valley engaged three independent
appraisers to conduct fair market valuations of the Put Option Assets. The average fair market value pursuant to such appraisals for the Put Option Assets was $137.5 million. Therefore, upon closing of the Asset Purchase Agreement, Genco received an
additional payment of $37.5 million from Medina Valley. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The AER Transaction Agreement provides that if the Put Option Assets are

Completion of Acquisition or Disposition of Assets.
On October 11, 2013, Ameren
Energy Generating Company ("Genco"), an indirect wholly owned subsidiary of Ameren Corporation ("Ameren"), completed the previously announced sale of its Elgin, Gibson City, and Grand Tower gas-fired energy centers (the "Put
Option Assets") to AmerenEnergy Medina Valley Cogen, LLC ("Medina Valley"), a direct wholly owned subsidiary of Ameren, pursuant to the Asset Purchase Agreement (as defined below) for $137.5 million.
As previously reported, on March 14, 2013, Ameren entered into a transaction agreement (the "AER Transaction Agreement") to
divest its wholly owned subsidiary, Ameren Energy Resources Company ("AER"), to Illinois Power Holdings, LLC ("IPH"), an indirect wholly owned subsidiary of Dynegy, Inc. Prior to entry into the AER Transaction Agreement,
(i) the original put option agreement, dated March 28, 2012, between Genco and Ameren Energy Resources Generation Company ("AERG") was novated and amended such that the rights and obligations of AERG under the agreement were
assigned to and assumed by Medina Valley and (ii) Genco exercised its option under the amended put option agreement to sell the Put Option Assets to Medina Valley.
Pursuant to the amended put option agreement, Genco and Medina Valley entered into an asset purchase agreement, dated as of March 14,
2013 (the "Asset Purchase Agreement") and Genco received an initial payment of $100 million (the "Initial Payment") for the Put Option Assets. The Asset Purchase Agreement provided that Genco would receive an additional payment
upon closing of the Asset Purchase Agreement to the extent the average of the fair market value for the Put Option Assets, as determined by three independent appraisals, exceeded the Initial Payment. Genco and Medina Valley engaged three independent
appraisers to conduct fair market valuations of the Put Option Assets. The average fair market value pursuant to such appraisals for the Put Option Assets was $137.5 million. Therefore, upon closing of the Asset Purchase Agreement, Genco received an
additional payment of $37.5 million from Medina Valley.
The AER Transaction Agreement provides that if the Put Option Assets are
subsequently sold by Medina Valley within two years of the Asset Purchase Agreement closing, Medina Valley will pay Genco any proceeds from such sale, net of taxes and other expenses, in excess of the amounts previously paid to Genco.
