Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers

As discussed in Item 5.07 below, the stockholders of First Industrial Realty Trust, Inc. (the “Company”) approved the Charter Amendments (as defined in Item 5.07 below) at the Company’s 2013 annual meeting of stockholders (the “Annual Meeting”), including an amendment to immediately declassify the Company’s Board of Directors. In order to effect the immediate declassification of the Board of Directors, directors whose terms were set to expire at the Company’s 2014 and 2015 annual meetings of stockholders resigned from the Board of Directors at the Annual Meeting immediately following the approval of each of the Charter Amendments by the Company’s stockholders, and the nomination of each of such directors to serve for a one-year term expiring at the 2014 annual meeting of stockholders was presented to the Company’s stockholders for approval. As discussed in Item 5.07 below, each director is now serving a one-year term expiring at the 2014 annual meeting of stockholders and until his successor is duly elected and qualifies.

Item 5.03 Amendments to Articles of Incorporation or Bylaws; Change in Fiscal year

As discussed in Item 5.07 below, the Company’s stockholders approved the Charter Amendments at the Annual Meeting. The Charter Amendments were adopted by the Company’s Board of Directors subject to stockholder approval at the Annual Meeting, and have thus become effective.

The text of the Articles of Amendment, effective May 9, 2013, reflecting the Charter Amendments, is attached as Exhibit 3.1 to this report.

On February 27, 2013, the Board of Directors approved, subject to approval of the Company’s stockholders at the Annual Meeting of each of the Charter Amendments, certain amendments to the Company’s Amended and Restated Bylaws that would (i) implement a plurality vote standard in contested director elections, (ii) modify the Company’s “advance notice” bylaw to require that notice of stockholder proposals or director nominations to be considered at an annual meeting be provided to the Company not less than 120 days nor more than 150 days prior to the anniversary date of the mailing of the proxy statement relating to the prior year’s annual meeting and (iii) make certain other changes designed to update and modernize the bylaws. As a result of the stockholders’ approval of each of the Charter Amendments at the Annual Meeting, the above-described amendments to the Company’s Amended and Restated Bylaws have become effective.

The text of the Company’s Second Amended and Restated Bylaws, effective May 9, 2013, is attached as Exhibit 3.2 to this report.
