Ladies and Gentlemen:
We are rendering this opinion in connection with the registration statement on Form S-3 (the “Registration Statement”) filed by Comstock Resources, Inc. (the “Company”), a Nevada corporation, with the Securities and Exchange Commission (the “Commission”) under Rule 462(b) under the Securities Act of 1933, as amended (the “Securities Act”), on or about the date hereof. The Registration Statement incorporates by reference the registration statement on Form S-3 (File No. 333-238113) filed by the Company with the Commission under the Securities Act on May 8, 2020, as amended by the Pre-Effective Amendment No. 1 filed with the Commission on May 22, 2020, and declared effective by the Commission on June 1, 2020 (the “Related Registration Statement”), including each of the documents filed by the Company with the Commission and incorporated or deemed to be incorporated therein and all exhibits thereto. Pursuant to the Registration Statement, the Company is registering $50,000,000 of unsecured debt securities (the “Debt Securities”) and the guarantees of the Company’s Debt Securities by the Co-Registrants (the “Guarantees”).
The Debt Securities and the Guarantees will be issued pursuant to the indenture, dated June 23, 2020 (the “Indenture”), entered into by the Company, each of the Co-Registrants, as guarantors, and American Stock Transfer & Trust Company, LLC (the “Trustee”) qualified to act as such under the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”), as amended by the First Supplemental Indenture, dated June 23, 2020, which are Exhibit 4.1 and Exhibit 4.2, respectively, to the Company’s Current Report on Form 8-K filed with the Commission on June 24, 2020, and which are incorporated by referenced into the Registration Statement through incorporation of the Related Registration Statement, and as the same may hereafter be supplemented from time to time, among other things at the time of and in connection with the issuance of the Debt Securities and any Guarantees.
In connection with this opinion, we have examined originals or copies, certified, or otherwise identified to our satisfaction, of: (i) the Second Amended and Restated Articles of Incorporation (“Restated Articles of Incorporation”) and Amended and Restated Bylaws (“Bylaws”) of the Company, each as amended to date and currently in effect, and similar organizational documents for each of the Co-Registrants; (ii) the Registration Statement and the Related Registration Statement; (iii) the prospectus contained in the Registration Statement (the “Prospectus”); and (iv) resolutions adopted by the Board of Directors of the Company (the “Board of Directors”) and the board of directors (or similar governing body) of each Co-Registrant relating to the registration of the Debt Securities and Guarantees and related matters. We have also reviewed such other documents and records of the Company and each Co-Registrant and such agreements, certificates and receipts of public officials, certificates of officers or other representatives of the Company and each Co-Registrant and others, and such other documents as we have deemed necessary or appropriate as a basis for the opinions set forth herein.
In rendering the opinions contained herein, we have, with your permission, made the following assumptions: (i) all documents submitted to or reviewed by us, including all amendments and supplements thereto, are accurate and complete and, if not originals, are true, correct, and complete copies of the originals; (ii) the signatures on each of such documents by the parties thereto are genuine; (iii) each individual who signed such documents had the legal capacity to do so; and (iv) all persons who signed such documents on behalf of a business entity were duly authorized to do so.
