SECTION 4 - Matters Related to Accountants and Financial Statements

Item 4.01 Changes in Registrant's Certifying Accountant.

(a)(1) Dismissal of Independent Registered Public Accounting Firm.

On February 26, 2007, Southwestern Energy Company's Audit Committee approved the dismissal of PricewaterhouseCoopers LLP ("PricewaterhouseCoopers") as the independent registered public accounting firm for the Southwestern Energy Company 401(k) Savings Plan (the “Plan”). PricewaterhouseCoopers will continue to act as the independent registered public accounting firm for Southwestern Energy Company, the Plan's sponsor (the "Company").

PricewaterhouseCoopers' reports on the financial statements of the Plan for the years ended December 31, 2005 and 2004 contained no adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principle. During the years ended December 31, 2005 and 2004 and through February 26, 2007, there were no disagreements with PricewaterhouseCoopers on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of PricewaterhouseCoopers, would have caused PricewaterhouseCoopers to make reference to the subject matter of the disagreements in PricewaterhouseCoopers’ reports on the Plan’s financial statements for such years.

During the years ended December 31, 2005 and 2004 and through February 26, 2007, there have been no reportable events, as defined in Item 304 (a)(1)(v) of Regulation S-K, in connection with the Plan.

The Company has requested a letter from PricewaterhouseCoopers stating whether or not PricewaterhouseCoopers agrees with the above disclosure. A copy of such letter is filed as Exhibit 16.1 to this Form 8-K.

(a)(2) Engagement of New Independent Registered Public Accounting Firm.

The engagement of a new independent accountant by the Plan will be reported separately on Form 8-K at the appropriate time.
