Item 5.07 Submission of Matters to a Vote of Security Holders.

At the 2011 Annual Meeting of Shareholders (the “Annual Meeting”) of McGrath RentCorp (the “Company”), held on June 8, 2011, the following proposals were voted on by the Company’s shareholders, as set forth below.

The Company’s shareholders (i) elected each of the director nominees, (ii) ratified the appointment of Grant Thornton LLP as the Company’s independent registered public accounting firm for the Company’s fiscal year ending December 31, 2011, (iii) voted for the approval on a non-binding, advisory basis of the compensation of the Company’s named executive officers, and (iv) voted for the approval on a non-binding, advisory basis of a one-year frequency of holding a non-binding, advisory vote on the compensation of the Company’s named executive officers.

Proposal 1. Election of Directors.

Proposal 2. Ratification of the appointment of Grant Thornton LLP as the Company’s independent registered public accounting firm for the Company’s fiscal year ending December 31, 2011.

Proposal 3. Non-binding, advisory vote on the compensation of the Company’s named executive officers.

Proposal 4. Non-binding, advisory vote on the frequency of holding a non-binding, advisory vote on the compensation of the Company’s named executive officers.

With respect to Proposal 1, we note that approximately 23.0 percent of shareholders voted “WITHHOLD” for Robert P. McGrath. The Company believes that these votes were likely cast as a result of, and in accordance with, a report by Institutional Shareholder Services (“ISS”), which included a recommendation of a “WITHHOLD” vote for Mr. McGrath. This recommendation was based on ISS’s determination that Mr. McGrath was an “affiliated outside director” because he is the founder of the Company and formerly served as the Company’s Chief Executive Officer until March 2003. It is ISS’s policy that affiliated outsiders should not serve on the Company’s independent board committees. The Board of Directors has determined that Mr. McGrath is “independent” as defined in the listing standards of the NASDAQ Stock Market and the regulations of the SEC. The Company believes that Mr. McGrath contributes significant value as a member of the Audit and Corporate Governance and Nominating Committees and is unbiased in carrying out his responsibilities as a committee member.

With respect to Proposal 4, consistent with the stated preference of a majority of the Company’s shareholders, the Board of Directors has determined that it will include a non-binding, advisory vote on the compensation of its named executive officers in its proxy materials every year until the next required non-binding, advisory vote on the frequency of holding a vote on the compensation of the Company’s named executive officers, which will occur no later than our annual meeting of shareholders in 2017.
