Item 1.01. Entry into a Material Definitive Agreement.

On March 2, 2011, EnergyConnect Group, Inc., an Oregon corporation (“EnergyConnect”), entered into an Agreement and Plan of Merger (the “Merger Agreement”), by and among EnergyConnect, Johnson Controls Holding Company, Inc., a Delaware corporation, (“JCI Holding”), and Eureka, Inc., an Oregon corporation and wholly owned subsidiary of JCI Holding (“Merger Sub”), pursuant to which Merger Sub will merge with and into EnergyConnect, with EnergyConnect as the surviving corporation and a wholly owned subsidiary of JCI Holding (the “Merger”).

Pursuant to the terms of the Merger Agreement, at the effective time of the Merger, each issued and outstanding share of EnergyConnect common stock, no par value, will be converted into the right to receive Twenty-Two and 53/100 Cents ($.2253) pursuant to and in accordance with the terms and conditions set forth in the Merger Agreement (the “Merger Consideration”).

Each outstanding option to purchase EnergyConnect common stock granted under EnergyConnect’s stock plans will be fully accelerated and converted into the right to receive cash payment, if any, equal to the aggregate Merger Consideration (without interest and less any applicable taxes) payable on the shares underlying such option minus the aggregate exercise price for such option. Each option unexercised at the time of the consummation of the Merger will be cancelled. In addition, each unvested restricted stock unit or share of restricted stock issued by EnergyConnect will automatically vest and be converted into the right to receive the Merger Consideration underlying such unit or share.

EnergyConnect has made certain customary representations, warranties and covenants in the Merger Agreement, including, among others, covenants to (i) conduct its businesses in the ordinary course consistent with past practices during the interim period between the execution of the Merger Agreement and the consummation of the Merger, and (ii) use its reasonable best efforts to take any action necessary or advisable to cause the conditions to the consummation of the Merger to be satisfied as promptly as practicable. In addition, EnergyConnect has agreed not to initiate, solicit, knowingly encourage or knowingly facilitate (including by way of furnishing nonpublic information or assistance) any inquiries or the making of any proposal or other action that constitutes, or may reasonably be expected to lead to a takeover proposal, enter into discussions or negotiate with any third party regarding any takeover proposal, or enter into any agreement related to any takeover proposal, subject to certain exceptions.

Completion of the Merger is subject to various customary closing conditions, including, but not limited to, (i) approval and adoption of the Merger Agreement by EnergyConnect’s shareholders, (ii) the absence of any order or injunction prohibiting the consummation of the Merger, (iii) the accuracy of the representations and warranties of each party, (iv) performance, in all material respects, of all obligations and compliance with, in all material respects, agreements and covenants to be performed or complied with by each party, (v) the absence of a material adverse effect on EnergyConnect, (vi) EnergyConnect having obtained cancellation acknowledgments from holders of certain warrants or such warrants having expired and (vii) consents having been obtained from EnergyConnect’s lender, any utility, independent system operator or market regulator whose approval is required by contract or applicable law, and the U.S. Federal Energy Regulatory Commission.

The Merger Agreement contains certain termination rights for each of JCI Holding and EnergyConnect, including EnergyConnect’s right to terminate the Merger Agreement under certain circumstances to pursue an unsolicited superior proposal. In addition, the Merger Agreement provides that upon termination of the Merger Agreement under specified circumstances, including termination by EnergyConnect to pursue an unsolicited superior proposal, EnergyConnect is required to pay JCI Holding a termination fee of $1,600,000.

The board of directors of EnergyConnect approved the Merger Agreement and determined that the Merger Agreement and the Merger were advisable, fair to and in the best interest of EnergyConnect and its shareholders.

The foregoing description of the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Merger Agreement, a copy of which is attached hereto as Exhibit 2.1 and incorporated herein by reference. A joint press release, issued on March 3, 2011, announcing the signing of the Merger Agreement, is attached as Exhibit 99.1 hereto and is incorporated herein by reference.

The Merger Agreement has been included to provide investors and security holders with information regarding its terms. It is not intended to provide any other factual or financial information about JCI Holding, Merger Sub or EnergyConnect, or their respective subsidiaries and affiliates. The representations, warranties and covenants contained in the Merger Agreement were made only for purposes of that agreement and as of specific dates; were solely for the benefit of the parties to the Merger Agreement; may be subject to limitations agreed upon by the parties, including being qualified by confidential disclosures made for the purposes of allocating contractual risk between the parties to the Merger Agreement instead of establishing these matters as facts; and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors. Investors should not rely on the representations, warranties and covenants or any description thereof as characterizations of the actual state of facts or condition of JCI Holding, Merger Sub or EnergyConnect or any of their respective subsidiaries or affiliates. Moreover, information concerning the subject matter of the representations, warranties and covenants may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in public disclosures by JCI Holding and EnergyConnect. The Merger Agreement should not be read alone, but should instead be read in conjunction with the other information regarding the parties and the Merger that will be contained in, or incorporated by reference into, the proxy statement that EnergyConnect will be filing in connection with the Merger, as well as in the other filings that EnergyConnect makes with the Securities and Exchange Commission (“SEC”).

Neither Johnson Controls, Inc. nor EnergyConnect undertakes any obligation to update or revise these statements, whether as a result of new information, future events or otherwise.
