NOTE 8 - RELATED PARTY TRANSACTIONS

The Ameren Companies have engaged in, and may in the future engage in, affiliate transactions in the normal course of business. These transactions primarily consist of natural gas and power purchases and sales, services received or rendered, and borrowings and lendings. Transactions between affiliates are reported as intercompany transactions on their financial statements, but are eliminated in consolidation for Ameren's financial statements. For a discussion of our material related party agreements, see Note 14 - Related Party Transactions under Part II, Item 8, of the Form 10-K.

Put Option Agreement and Guaranty

On March 28, 2012, Genco entered into a put option agreement with AERG. The put option gives Genco the option to sell to AERG all, but not less than all, of the Grand Tower, the Gibson City, and the Elgin energy centers. If Genco exercises the put option, the purchase price for all three energy centers will be the greater of $100 million or the fair market value of the energy centers, as determined by three third-party appraisers in accordance with the terms of the agreement. Upon exercise of the put option, the $100 million minimum purchase price would be payable to Genco within one business day. Genco may exercise the put option at any time from March 28, 2012 through March 28, 2014. The put option may be extended indefinitely for additional one-year periods by agreement of AERG and Genco. If Genco exercises the put option, the closing of the sale of all three energy centers will be subject to the receipt of all necessary regulatory approvals. In exchange for entering into the put option agreement, Genco paid AERG a put option premium of $2.5 million. The put option premium paid by Genco is reflected on Genco's March 31, 2012 consolidated balance sheet as an "Other asset" and will be amortized over two years. The amortization expense will be eliminated in the consolidation of Ameren's financial statements.

The put option agreement requires AERG to secure and maintain an Ameren guaranty of payment of contingent obligations under the agreement. Ameren and AERG entered into such a guaranty agreement on March 28, 2012. AERG's primary source of financing is the non-state-regulated subsidiary money pool. If Genco exercises its put option, AERG would request a borrowing from the non-state-regulated subsidiary money pool to fund amounts due to Genco under the put option agreement. However, borrowings from the money pool are subject to Ameren control, and Ameren would consider AERG's borrowing request based on the facts and circumstances existing at that time. If Ameren decided not to provide AERG with a non-state-regulated subsidiary money pool loan necessary to fund AERG's obligations under the put option agreement, Ameren would fulfill AERG's payment obligations directly in accordance with the terms of the guaranty agreement. Therefore, the Ameren guaranty ensures the payment of all sums that may be owed by AERG to Genco under the terms of the put option agreement. The guaranty shall remain in effect until either AERG or Ameren satisfies all of the payment obligations under the put option agreement, or the put option agreement is terminated and no further payments are owed by AERG to Genco. As of March 31, 2012, Genco had not exercised the put option and thus Ameren had no exposure to this intercompany guaranty.

Electric Power Supply Agreements

During the second quarter of 2012, Ameren Illinois used a RFP process, administered by the IPA, to contract capacity and energy products for the period from June 1, 2012, through May 31, 2015. Both Marketing Company and Ameren Missouri were among the winning suppliers in the capacity RFP process. In April 2012, Marketing Company contracted to supply a portion of Ameren Illinois' capacity requirements to Ameren Illinois for less than $1 million and $4 million for the 12 months ending May 31, 2013 and 2015, respectively. In April 2012, Ameren Missouri contracted to supply a portion of Ameren Illinois' capacity requirements to Ameren Illinois for $1 million and $3 million for the 12 months ending May 31, 2014 and 2015, respectively. Ameren Illinois is currently reviewing the results of the energy products procurement proceeding.

Collateral Postings

Under the terms of the Illinois power procurement agreements entered into through a RFP process administered by the IPA, suppliers must post collateral under certain market conditions to protect Ameren Illinois in the event of nonperformance. The collateral postings are unilateral, meaning that only the suppliers would be required to post collateral. Therefore, Ameren Missouri, as a winning supplier of capacity, and Marketing Company, as a winning supplier of capacity and financial energy swaps, may be required to post collateral. As of December 31, 2011 and March 31, 2012, there were no collateral postings required of Ameren Missouri or Marketing Company related to the Illinois power procurement agreements.
