Fourth Amendment to Credit Agreement

On March 23, 2018, WildHorse Resource Development Corporation (the “Company”), Wells Fargo Bank, National Association, as administrative agent (the “Administrative Agent”), and the other parties thereto entered into a fourth amendment to the Credit Agreement, dated as of December 19, 2016 (as amended, the “Credit Agreement”), by and among the Company, the Administrative Agent and the other agents and lenders party thereto (the “Fourth Amendment”). The Fourth Amendment, among other things, increases (i) the Borrowing Base (as defined in the Credit Agreement) from $875,000,000 to $1,050,000,000 and (ii) the Aggregate Elected Commitment Amounts (as defined in the Credit Agreement) to $1,050,000,000, subject to the other terms and conditions of the Fourth Amendment and the Credit Agreement.

The representations and warranties of the Company and its subsidiaries in the Fourth Amendment were made only for purposes of that agreement and as of specific dates and were solely for the benefit of the lenders party thereto. The Fourth Amendment is a contractual document that establishes and governs the legal relations among the parties thereto and is not intended to be a source of factual, business, or operational information about the Company and its subsidiaries or their future activities. Accordingly, such representations and warranties in the Fourth Amendment should not be relied upon as characterizations of the actual state of facts, circumstances or plans.

Certain of the lenders under the Credit Agreement and their respective affiliates have, from time to time, performed, and may in the future perform, various financial advisory, commercial and investment banking services for the Company and its subsidiaries, for which they received or will receive customary fees and expenses. Certain affiliates of the lenders under the Credit Agreement have acted, and may in the future act, as underwriters of certain of the Company’s debt and equity issuances.

The foregoing summary of the Fourth Amendment is not complete and is qualified in its entirety by reference to the full text of the Fourth Amendment, a copy of which is filed as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference.

The description of the Fourth Amendment above under Item 1.01 is incorporated in this Item 2.03 by reference.
