Ladies and Gentlemen:

We have acted as special counsel to Owens & Minor, Inc., a Virginia corporation (the “Company”), Owens & Minor Distribution, Inc., a Virginia corporation and a wholly-owned subsidiary of the Company (“O&M Distribution”), and Owens & Minor Medical, Inc., a Virginia corporation and a wholly-owned subsidiary of the Company (“O&M Medical” and, together with O&M Distribution, the “Guarantors”), in connection with the registration of an indeterminate amount of debt securities of the Company (the “Debt Securities”) and guarantees of the Debt Securities by the Guarantors (the “Guarantees” and, together with the Debt Securities, the “Securities”), as set forth in the Registration Statement on Form S-3 (the “Registration Statement”) filed by the Company and the Guarantors on the date hereof with the Securities and Exchange Commission (the “Commission”) pursuant to the Securities Act of 1933, as amended (the “Act”). The Securities will be offered pursuant to an indenture (as it may be supplemented from time to time, the “Indenture”), among the Company, the Guarantors and U.S. Bank National Association, as trustee (the “Trustee”). The Securities are to be issued in one or more series and will be offered on a continuous or delayed basis pursuant to Rule 415 of the Act, from time to time as set forth in the Registration Statement, the prospectus contained therein (the “Prospectus”) and any amendments or supplements thereto.

This opinion is being furnished in accordance with the requirements of Item 16 of Form S-3 and Item 601(b)(5)(i) of Regulation S-K.

We have examined originals or reproductions or certified copies of such records of the Company and the Guarantors, certificates of officers of the Company and the Guarantors and of public officials and such other documents as we have deemed relevant and necessary for the purpose of rendering this opinion, including, among other things:

The opinions set forth above are subject to the qualification that the validity and enforcement of the Company’s obligations under the Indenture and the Debt Securities and the Guarantors’ obligations under the Guarantees may be subject to (i) the effects of bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium or other laws now or hereafter in effect relating to or affecting creditors’ rights generally, (ii) general principles of equity (whether considered in a proceeding at law or in equity) and (iii) concepts of materiality, unconscionability, reasonableness, impracticability or impossibility of performance and any implied covenant of good faith and fair dealing.
