Director Restricted Stock Unit Awards

Through the 2003 OfficeMax Incentive and Performance Plan (the “Plan”) each non-employee director annually receives a form of long-term equity compensation with a value of $100,000. On July 25, 2012, the Executive Compensation Committee of the board of directors determined that the 2012 director award would be granted in the form of restricted stock units (“RSUs”). In connection with the grant, each director will enter into a 2012 Director Restricted Stock Unit Award Agreement (an “Agreement”), in the form attached hereto as Exhibit 99.1.

The Agreement states that the award is subject to the terms of the Plan. Each award will vest six months following the grant date if the recipient is still a Company director at that time. An award will vest immediately if a director terminates board service prior to the six month anniversary of the grant date due to such director’s death or total and permanent disability. Unless otherwise approved by the board, if a director terminates board service prior to the six month anniversary of the grant date for a reason other than death or total and permanent disability, such director’s award will be forfeited. Vested RSUs will be payable six months following the date of a director’s termination of board service due to such director’s (i) retirement or resignation from the board, (ii) death or (iii) total and permanent disability. The vesting and payment of the RSUs may accelerate upon a change in control in certain circumstances. The award is not transferable. Holders of RSUs have no voting rights but do receive notional dividends (if any are paid), which are accumulated and paid in cash at the time the award is paid.

This summary does not purport to be complete and is subject to and qualified in its entirety by reference to the text of the form of Agreement, included as Exhibit 99.1 to this filing. Exhibit 99.1 is incorporated by reference into this Item 5.02.
