Ladies and Gentlemen:

We have acted as counsel to DXP Enterprises, Inc., a Texas corporation (the “Company”), in connection with the registration under the Securities Act of 1933, as amended (the “Securities Act”), of an aggregate of 500,000 shares (the “Shares”) of the Company’s common stock, par value $0.01 per share, that are reserved for issuance under the DXP Enterprises, Inc. 2016 Omnibus Incentive Plan (the “Plan”), as described in the Company’s Registration Statement on Form S-8 (as may subsequently be amended, the “Registration Statement”).

In connection with the foregoing, we have examined the Plan and originals or copies of the corporate records of the Company, certificates and other communications of public officials, certificates of officers of the Company and such other documents as we have deemed relevant or necessary for the purpose of rendering the opinions expressed herein. As to questions of fact material to those opinions, we have, to the extent we deemed appropriate, relied on certificates of officers of the Company and on certificates and other communications of public officials. We have assumed the genuineness of all signatures on, and the authenticity of, all documents submitted to us as originals, the conformity to authentic original documents of all documents submitted to us as copies thereof, the due authorization, execution and delivery by the parties thereto other than the Company of all documents examined by us, and the legal capacity of each individual who signed any of those documents.

Based upon the foregoing, and having due regard for such legal considerations as we deem relevant, we are of the opinion that the Shares, when issued and sold in the manner referred to in the Plan and pursuant to the agreements that accompany the Plan will be validly issued, fully paid and nonassessable.

The opinions expressed herein are limited exclusively to applicable federal laws of the United States of America, and applicable provisions of, respectively, the Texas Constitution, the Texas Business Organizations Code and reported judicial interpretations of such law, in each case as currently in effect, and we are expressing no opinion as to the effect of the laws of any other jurisdiction.

Norton Rose Fulbright US LLP is a limited liability partnership registered under the laws of Texas.
