*On March 26, 2012, the common stock of Southern Union Company (the “Company”) was acquired in a merger transaction.  Additionally, Company common stock was deregistered and is no longer publicly held.   Employee salary deferral contributions and Company matching contributions under the Southern Union Savings Plan may no longer be invested in Company common stock. Therefore, pursuant to SEC Release 33-6188, plan interests are exempt from registration and Form 11-K filings are no longer required.
