On December 8, 2017, Eclipse Resources-PA, LP (“Eclipse PA”), a wholly owned subsidiary of Eclipse Resources Corporation (the “Company”), and the Company entered into a Purchase and Sale Agreement (the “Travis Peak Agreement”) with Travis Peak Resources, LLC (“Travis Peak”). Pursuant to the Travis Peak Agreement, Eclipse PA agreed to purchase certain oil and gas leases, wells and other oil and gas rights and interests held by Travis Peak covering approximately 44,500 net acres located in the counties of Tioga and Potter in the Commonwealth of Pennsylvania (such transaction, the “Travis Peak Transaction”). The purchase price for the Travis Peak Transaction is $93.7 million (subject to customary adjustments) (the “Purchase Price”) and is payable entirely in shares (the “Shares”) of the Company’s common stock, par value $0.01 per share (the “Common Stock”). Pursuant to the Travis Peak Agreement, the number of Shares to be issued to Travis Peak will equal the Purchase Price divided by the 30 consecutive-day volume weighted average price per share of the Common Stock ending on the second trading day immediately preceding the closing date (the “Closing Date VWAP”); provided, that the Travis Peak Agreement includes a collar mechanism that provides if the Closing Date VWAP is less than $2.35, then the Closing Date VWAP will equal $2.35 and if the Closing Date VWAP is more than $2.60, then the Closing Date VWAP will equal $2.60. The Travis Peak Agreement also contains customary representations, warranties, covenants and indemnities by the parties.

The Company expects the Travis Peak Transaction to close in January 2018, subject to the satisfaction of customary closing conditions; provided, that the Travis Peak Transaction will have an effective date of September 1, 2017 and contemplates a second closing for purposes of curing any title or environmental defects with respect to the properties being acquired by Eclipse PA.

In connection with the closing of the Travis Peak Transaction, the Company and Eclipse PA have agreed to enter into a registration rights agreement with Travis Peak pursuant to which, among other things, (i) the Company will use commercially reasonable efforts to prepare and file with the Securities and Exchange Commission a Registration Statement of the Company (the “Mandatory Shelf Registration Statement”) on Form S-3 (or, if the Company is not eligible to use Form S-3, on Form S-1) no later than March 31, 2018 to register the offer and resale, on a continuous or delayed basis pursuant to Rule 415 under the Securities Act of 1933, as amended (the “Securities Act”), of the Shares to be issued to Travis Peak under the Travis Peak Agreement, and (ii) if the Company proposes to register an offering of Common Stock at a time when the Mandatory Shelf Registration Statement is not then effective (subject to certain exceptions), the Company will notify all holders of registrable securities to allow them to include a specified number of their shares of Common Stock in that offering.
