On May 11, 2011, at the Registrant’s Annual Meeting of Stockholders, Daniel J. Good and Richard W. Gochnauer retired from the Board of Directors.

On May 11, 2011, Richard W. Gochnauer retired as the Registrant’s Chief Executive Officer as previously announced in a Form 8-K filed on December 20, 2010.

Also as previously announced, P. Cody Phipps, age 49, was appointed by the Board of Directors to serve as the Registrant’s President and Chief Executive Officer effective May 11, 2011. Mr. Phipps will hold such office until his successor is appointed and qualified or until his earlier removal or resignation.

Mr. Phipps joined the Registrant in August, 2003 as Senior Vice President, Operations. From October 2006 until September 2010, Mr. Phipps served as President, United Stationers Supply, a division of the Registrant’s wholly-owned subsidiary, United Stationers Supply Co. On September 1, 2010, he was appointed President and Chief Operating Officer of the Registrant, which position he held until his current promotion to President and Chief Executive Officer.

Mr. Phipps is a party to an Executive Employment Agreement with the Registrant, the form of which has been described in, and filed as an exhibit to, the Registrant’s prior SEC filings.

On May 11, 2011, the Registrant’s Board of Directors appointed Mr. Robert B. Aiken as a member of the Audit Committee and Human Resources Committee of the Board and Mr. Phipps as a member of the Executive Committee of the Board.

A Press Release announcing the appointment of Mr. Phipps to President and Chief Executive Officer of the Registrant is attached as Exhibit 99.1 and incorporated herein by reference.

On May 11, 2011, the Registrant’s shareholders approved the Amended and Restated 2004 Long-Term Incentive Plan, which is described under Proposal 3 in the Registrant’s proxy statement filed with the Securities and Exchange Commission on March 30, 2011, which description is incorporated herein by reference.

On May 11, 2011, the Registrant held its Annual Meeting of Stockholders. The voting results from the annual meeting are as follows:

On May 11, 2011 the Board of Directors of the Registrant approved a dividend of $0.13 per share payable July 15, 2011 to stockholders of record as of the close of business on June 15, 2011. Because the record date for this cash dividend occurs after the record date of the previously announced stock split, it is equivalent to $0.26 per pre-split common share.

A copy of the Registrant’s press release is attached as Exhibit 99.2 hereto and is incorporated herein by reference.

The following exhibits are filed herewith:
