Explanation of Responses:

1. Purchased through the Company's 401(k) plan from June 15, 2007, through December 12, 2007. The information in this report is based on a plan statement dated as of November 30, 2007.

2. Each share of phantom stock represents the right to receive the economic equivalent of one share of Southwestern Energy Company common stock.

3. Shares of phantom stock are payable in cash following termination of the reporting person's employment with Southwestern Energy Company. The reporting person may transfer his phantom stock account into an alternative investment account at any time.

4. The common stock held in the Southwestern Energy Company Nonqualified Retirement Plan (the "NQ Plan") investment fund was previously reported in Table 1 as a non-derivative security indirectly owned by the reporting person. Prospectively, the balance of common stock held in the NQ Plan investment fund on behalf of the insider will be reported under Table II as phantom stock.
