Effective March 19, 2018, Bill Barrett Corporation (the “Company”), Circle B Land Company LLC, a wholly-owned subsidiary of the Company, and HighPoint Resources Corporation (f/k/a/ Red Rider Holdco, Inc.) (“HighPoint”) entered into a Fifth Amendment, Waiver and Consent to Third Amended and Restated Credit Agreement (such agreement, the “Credit Agreement”) and a First Amendment to Third Amended and Restated Guaranty and Collateral Agreement (such agreement, the “Guaranty and Collateral Agreement”) with JPMorgan Chase Bank, N.A., as Administrative Agent, and the lenders party thereto (the “Credit Agreement Amendment”). Pursuant to the Credit Agreement Amendment, among other things, (i) HighPoint became a guarantor under the Credit Agreement by entering into the Guaranty and Collateral Agreement, and pledged to the Administrative Agent, for the benefit of the lenders, its equity interest in the Company, (ii) financial reporting under the Credit Agreement following the mergers (as defined below) will be by HighPoint, and (iii) the lenders consented to certain actions related to the mergers.

Certain of the lenders under the Credit Agreement or their affiliates have provided and may continue to provide banking, financial, or other services to the Company and its affiliates. J.P. Morgan Securities LLC, an affiliate of the Administrative Agent, acted as lead underwriter in the Company’s December 2017 equity offering. The lenders have received, and may in the future receive, customary fees and commissions for their services.

The foregoing summary is qualified in its entirety by reference to the Credit Agreement Amendment, which is attached hereto as Exhibit 10.1.

Post-Closing Merger Agreement

After the effective time of the mergers as described in Item 2.01, the Company, then a Delaware corporation and direct wholly owned subsidiary of HighPoint, entered into an Agreement and Plan of Merger, dated as of March 19, 2018 (the “post-closing merger agreement”), with Fifth Creek Energy Operating Company, LLC (“Fifth Creek”), then a Delaware limited liability company and a direct wholly owned subsidiary of HighPoint, pursuant to which Fifth Creek merged with and into the Company, with the Company as the surviving entity in such merger. The description of the post-closing merger agreement contained herein does not purport to be complete and is qualified in its entirety by reference to the post-closing merger agreement, a copy of which is filed as Exhibit 2.1 hereto and incorporated herein by reference.

On March 16, 2018, the Company terminated the Equity Distribution Agreement, dated as of June 10, 2015 (the “Equity Distribution Agreement”), by and between the Company and Goldman Sachs & Co. (“Goldman Sachs”). The Equity Distribution Agreement was terminable at will upon written notification by the Company with no penalty. Pursuant to the Equity Distribution Agreement, the Company was entitled to issue and sell, from time to time, through or to Goldman Sachs shares of its common stock, par value $0.001 per share (“Company Common Stock”), having an aggregate offering price of up to $100,000,000 in an “at-the-market” offering program. As a result of the termination of the Equity Distribution Agreement, there will be no further sales of Company Common Stock thereunder.

On March 19, 2018, pursuant to the Agreement and Plan of Merger, dated as of December 4, 2017 (the “merger agreement”), by and among the Company, HighPoint, Fifth Creek, Rio Merger Sub, LLC, a Delaware limited liability company and a direct wholly owned subsidiary of HighPoint (“Rio Merger Sub”), Rider Merger Sub, Inc., a Delaware corporation and a direct wholly owned subsidiary of HighPoint (“Rider Merger Sub”), and, for limited purposes set forth in the merger agreement, Fifth Creek Energy Company, LLC, a Delaware limited liability company (“FCEC”), and NGP Natural Resources XI, L.P., a Delaware limited partnership (“NGP”), the Company and Fifth Creek completed a strategic combination of their respective businesses. Pursuant to the merger agreement, (i) Rider Merger Sub merged with and into the Company, with the Company as the surviving entity in such merger (the “BBG merger”), and (ii) Rio Merger Sub merged with and into Fifth Creek, with Fifth Creek as the surviving entity in such merger (the “Fifth Creek merger” and, collectively, the “mergers”), as a result of which the Company and Fifth Creek each became direct wholly owned subsidiaries of HighPoint.

Under the terms of the merger agreement, at the effective time of the mergers, each share of Company Common Stock issued and outstanding immediately prior to the effective time of the mergers was converted into the right to receive one fully paid and nonassessable share of common stock, par value $0.001 per share (“HighPoint Common Stock”), of HighPoint and all outstanding equity interests in Fifth Creek, in the aggregate, converted into the right to receive an aggregate of 100,000,000 shares of HighPoint Common Stock. As a result, former holders of Company Common Stock issued and outstanding immediately prior to the effective time of the mergers will receive in the aggregate 110,933,552 shares of HighPoint Common Stock, and the former holders of equity interests in Fifth Creek will receive 100,000,000 shares of HighPoint Common Stock. The shares of Company Common Stock will be suspended from trading on the NYSE prior to the open of trading on March 20, 2018, and shares of HighPoint Common Stock will begin regular-way trading on the NYSE under the ticker symbol “HPR” on March 20, 2018.

As provided in the merger agreement, at the effective time of the mergers, all options to purchase shares of Company Common Stock and all restricted stock and performance stock unit awards relating to Company Common Stock that were outstanding immediately prior to the effective time of the mergers were generally converted into corresponding awards relating to shares of HighPoint Common Stock on the same terms and conditions (excluding performance conditions) as applied prior to the effective time of the mergers (with performance stock unit awards converting into time-based restricted stock unit awards based on the greater of target performance and actual performance through the closing date).
