On May 16, 2016, Rice Energy Inc. (the “Company”) entered into the Eighth Amendment (the “Eighth Amendment”) to its Third Amended and Restated Credit Agreement, among the Company, Wells Fargo Bank, N.A., as administrative agent, and the lenders and other parties thereto (the “Amended Credit Agreement”). The lenders under the Amended Credit Agreement completed their semi-annual redetermination of the borrowing base scheduled for May 2016 (which was originally scheduled for on or about April 1, 2016). Following the redetermination, the Company’s borrowing base increased from $750 million to $875 million. The Eighth Amendment also established aggregate elected commitment amounts, which are $750 million as of the Eighth Amendment effective date. The next redetermination of the borrowing base is scheduled for October 2016.

The foregoing description of the Eighth Amendment is a summary only and is qualified in its entirety by reference to the complete text of the Eighth Amendment, a copy of which is attached as Exhibit 10.1 to this Current Report on Form 8-K and incorporated herein by reference.

The information set forth under Item 1.01 concerning the Eighth Amendment is incorporated herein by reference.

As previously announced, on April 12, 2016, Rice Energy Inc. (the “Company”) entered into a stalking horse asset purchase agreement with a subsidiary of Alpha Natural Resources, Inc. (“Alpha”) to acquire Marcellus and Utica assets in central Greene County, Pennsylvania for $200 million in cash, subject to purchase price adjustments (the “Alpha Acquisition”). On May 16, 2016, Alpha held an auction for the assets and a third party was the successful bidder with a bid of $339.5 million. In accordance with the bid protections approved by the bankruptcy court, the Company is entitled to a break-up fee and expense reimbursement in an aggregate amount of up to $3.5 million. Consummation of the acquisition is subject to bankruptcy court approval at a hearing that is currently scheduled for May 26, 2016.

On April 15, 2016, the Company completed a public offering of 29,858,891 shares of common stock resulting in net proceeds to the Company of approximately $312 million to fund the potential Alpha Acquisition and for general corporate purposes. In light of the outcome of the auction and upon completion of the offering, the Company has $1.5 billion of total liquidity. The Company intends to use the proceeds from the offering for general corporate purposes, which may include funding a portion of its 2017 capital budget.
