On October 5, 2009 Emerson Electric Co. and Globe Acquisition Corporation, a newly-formed subsidiary of Emerson, entered into a merger agreement with Avocent Corporation pursuant to which Emerson agreed to acquire Avocent Corporation for approximately $1.2 billion in cash. The merger agreement requires Emerson to make a tender offer to purchase Avocent's common stock for $25 per share. Following the completion of the offer, Globe Acquisition Corporation will merge with Avocent, and any remaining outstanding Avocent shares will convert into the right to receive $25 per share. After the merger, Avocent will be a wholly-owned subsidiary of Emerson.

The merger agreement requires Emerson to commence the tender offer by October 15, 2009. Emerson is only required to purchase the Avocent shares tendered in the tender offer if a majority of Avocent shares outstanding are tendered pursuant to the tender offer and not withdrawn and the other conditions to the offer are satisfied. The offer is not subject to a financing condition, but it is subject to other customary conditions, including the expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Act and the receipt of requisite approvals under certain foreign competition laws. Subject to certain conditions and limitations, Avocent has granted Emerson an option to purchase from Avocent after the successful completion of the tender offer enough additional Avocent shares so that Emerson will own more than 90% of Avocent's shares, in order to facilitate the completion of the merger through the "short-form" procedures available under Delaware law.

The merger agreement contains customary termination rights for both Emerson and Avocent. If the merger agreement is terminated under certain circumstances, Avocent is required to pay Emerson a termination fee of $35 million and/or reimburse Emerson for transaction expenses up to $7.5 million.

Avocent has agreed not to solicit or initiate discussions with third parties regarding other acquisition proposals and to certain other restrictions on its ability to respond to such proposals. The merger agreement includes other customary representations, warranties and covenants of Avocent and Emerson.

The foregoing description does not purport to be complete and is qualified in its entirety by reference to the merger agreement, which is filed as Exhibit 2.1 hereto, and is incorporated into this report by reference. The merger agreement is not intended to change any disclosure about Emerson or Avocent in their SEC filings. The representations and warranties contained in the merger agreement were negotiated primarily to establish termination conditions and allocate risk, rather than establish facts about the parties. The representations and warranties may be subject to contractual standards of materiality different from those generally applicable to shareholders.
