On April 4, 2013, CapLease, Inc. (the “Company”) entered into an underwriting agreement with Wells Fargo Securities, LLC, as representative of the several underwriters named in the underwriting agreement. Pursuant to the terms and conditions of the underwriting agreement, the Company agreed to sell 7,500,000 shares of common stock (the “Initial Shares”) to the underwriters, and granted the underwriters an option exercisable for 30 days to purchase up to an additional 1,125,000 shares of common stock (the “Option Shares”) to cover over-allotments of shares. The underwriters agreed to pay the Company a purchase price per share of $5.70135 (reflecting a price to the public of $5.97 per share, less an underwriting discount of $0.26865 per share). The underwriting agreement contained customary representations and warranties, indemnification provisions and closing conditions. The foregoing description of the underwriting agreement is qualified in its entirety by reference to the underwriting agreement filed as Exhibit 1 to this Form 8-K and incorporated herein by reference. Legal opinions delivered regarding the legality of the shares of common stock offered and certain tax matters are attached as Exhibits 5 and 8, respectively, to this Form 8-K.

The underwriters have exercised the over-allotment option in full, and the issuance and sale of the Initial Shares and the Option Shares closed on April 9, 2013.

The common stock was offered pursuant to the Company’s shelf registration statement on Form S-3 (File No. 333-171408), which was declared effective on February 14, 2011 by the Securities and Exchange Commission.
