RE: Form S-3 Automatic Shelf Registration Statement

Ladies and Gentlemen:

At your request, we have acted as special Texas counsel to Texstar Enterprises, Inc., a Texas corporation (“Subsidiary”) for the limited purpose of rendering a legal opinion as to matters of Texas law in connection with the filing of an automatic shelf registration statement on Form S-3 (the “Registration Statement”) with the United States Securities and Exchange Commission (the “Commission”) on September 1, 2017, pursuant to the Securities Act of 1933, as amended (the “Securities Act”) made by Dycom Industries, Inc., a Florida corporation (the “Parent”), Dycom Investments, Inc. (“Investments”), a Delaware corporation, and certain subsidiaries of the Parent (collectively, the “Subsidiaries,” and, together with the Parent, Investments and Subsidiary, the “Registrants”) relating to the issuance and offering, from time to time, of, among other securities and instruments, (1) debt securities of the Parent (“Parent Debt Securities”), (2) debt securities of Investments (“Investments Debt Securities” and, together with the Parent Debt Securities, the “Debt Securities”) and (3) guarantees of the Debt Securities (the “Guarantees”) by one or more of the Registrants (each a “Guarantor” and, collectively, the “Guarantors”), including, without limitation, the Guarantees pursuant to which Subsidiary will be a Guarantor (the “Subsidiary Guarantee”).

Pursuant to the prospectus forming a part of the Registration Statement (the “Prospectus”), the Parent and Investments propose to register the Debt Securities under the Securities Act as set forth in the Registration Statement and to be issued pursuant to one or more Indentures (the “Indentures”) among Parent or Investments, respectively, the Guarantors, if any, and the trustees parties thereto. Unless otherwise defined herein or unless the context requires otherwise, capitalized terms defined in the Registration Statement and Prospectus shall have the same meaning when used herein.

We have examined and rely solely upon the following documents for the purposes of rendering this opinion (collectively referred to as the “Documents”):

(a)

the Registration Statement;

(b)

the Prospectus.

As to certain matters of fact bearing upon the opinions expressed herein, we have reviewed and relied on originals or copies, certified or otherwise identified to our satisfaction, of the following (hereinafter the “Authority Documents”):

(a)

the Articles of Incorporation of Texstar Enterprises, Inc. dated April 24, 1991, as filed with the Secretary of State of the State of Texas;

(b)

(e)

Resolutions of the Board of Directors by Unanimous Written Consent in Lieu of Meeting of Texstar Enterprises, Inc. dated September 1, 2017.

In our examination we have assumed, without independent verification:

(i)

The genuineness of all signatures;

(ii)

The authenticity and completeness of all documents, records and instruments submitted to us as originals;

(iii)

With respect to copies of documents, records and instruments submitted to us, the conformity of such copies with the authentic originals thereof;

(vi)

As to matters of fact, the truthfulness of the representations made or otherwise incorporated in the Registration Statement and representations and statements made in certificates of public officials and officers of Subsidiary; and

(vii)

That the Subsidiary Guarantee, as issued and delivered, will comply with all restrictions, if any, applicable to Subsidiary whether imposed by any agreement or instrument to which Subsidiary is a party or by which it is bound or any court or other governmental or regulatory body having jurisdiction over Subsidiary or otherwise.

Based upon the foregoing assumptions and subject to the qualifications set forth below, it is our opinion that as of the date hereof:

Based solely on the Authority Documents, Subsidiary is a corporation duly formed, validly existing, and in good standing under the laws of the State of Texas.

Subsidiary has the requisite corporate power, corporate capacity and corporate authority to execute and deliver the Subsidiary Guarantee and to perform its obligations thereunder.

The Subsidiary Guarantee, upon being duly authorized by all necessary corporate action, executed by an authorized signatory and delivered, will be validly authorized, executed and delivered for Texas corporate law purposes by Subsidiary.
