Item 1.01 Entry into a Material Definitive Agreement

On February 6, 2007, Great Plains Energy entered into an Agreement and Plan of Merger (the “Merger Agreement”) pursuant to which Gregory Acquisition Corp., a wholly-owned subsidiary of Great Plains Energy, will merge into Aquila, Inc. (“Aquila”), a Delaware corporation, causing Aquila to become a wholly-owned subsidiary of Great Plains Energy. Immediately prior to the consummation of the merger, Black Hills Corporation, a South Dakota corporation (“Black Hills”) will acquire from Aquila its Colorado electric utility assets and Colorado, Iowa, Kansas and Nebraska gas utility assets pursuant to an Asset Purchase Agreement and a Partnership Interests Purchase Agreement, both dated as of February 6, 2007 (collectively, the “Asset Sale Agreements”). Each transaction is contingent on the completion of the other transaction, meaning that one transaction will not be completed unless the other transaction is completed.

The Merger Agreement and Asset Sale Agreements provide that they may be terminated if, among other things, the transactions have not been consummated by February 6, 2008 (the “Termination Date”).  Each agreement further provides that if any party to the agreement determines that additional time is necessary to obtain any of the specified regulatory consents or approvals, the Termination Date may be extended from time to time by written notice, up to August 6, 2008.  Great Plains Energy, Aquila and Black Hills previously extended the Termination Dates to May 1, 2008, and on April 29, 2008, the parties extended the Termination Dates to August 6, 2008.

Item 9.01	Financial Statements and Exhibits
(d) Exhibit No.
10.1	Mutual Notice of Extension dated as of April 29, 2008, by and among Black Hills Corporation, Aquila, Inc., and Great Plains Energy Incorporated.
