On September 11, 2011, BSQUARE Corporation (the “Company”) entered into a Share Purchase Agreement (the “Purchase Agreement”) with Philip Thomas Buckley, Norman Stephen Harper, Simon David Pooley, Alan John Rowe, Kevin Paul Heawood, Frank Michael Breeze and Julian Back (the “Sellers”), pursuant to which the Company has purchased all of the outstanding capital stock of MPC Data Limited, a U.K. corporation (“MPC”). The purchase price was £3,000,000, or approximately US$4,800,000, in cash (subject to a post-closing adjustment based on a determination of MPC’s actual net asset value at the closing of the transaction), plus an earn-out based on MPC’s revenue in the 12 months following the closing of the transaction. £750,000 (approximately US$1,200,000) of the purchase price has been placed in an escrow account which will be held to cover claims for 18 months after the closing. The Company and the Sellers have made customary warranties in the Purchase Agreement. In addition, the Sellers have agreed to indemnify the Company against certain losses. In connection with the transactions contemplated by the Purchase Agreement, the Company has entered into a lease agreement for the office space occupied by MPC in Trowbridge, England. The lease has a term of seven years.

The foregoing description of the Purchase Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Purchase Agreement, which is filed as Exhibit 10.1 hereto and incorporated herein by this reference. The Purchase Agreement has been included to provide investors with information regarding its terms; however it is not intended to provide any other factual information about the Company or MPC.

A copy of the Company’s press release relating to the MPC transaction is attached as Exhibit 99.1 hereto and incorporated herein by this reference.

The disclosure set forth above under Item 1.01 of this Current Report on Form 8-K is hereby incorporated by reference into this Item 2.01.
