"WDS").

         1.       Upon the closing of the sale of WDS, you will be paid by
                  Nortek, Inc. a cash incentive bonus of $300,000, payable on or
                  before the 10th day after Nortek receives payment from the
                  sale.

                  above shall be made if you are not employed by WDS (for any
                  reason) on the sale date or you have not committed the
                  necessary time and effort toward the sale of WDS which shall
                  include preparing due diligence materials, preparing
                  presentation material, meeting with potential buyers and

                  shall be paid, for the 24 months following such termination,
                  an annual amount equal to your 2003 base salary plus your 2003

                  made pursuant to this agreement are not counted toward any
                  pension, 401(k) or other benefit plan of WDS or Nortek.

         8.       This letter sets forth the entire understanding regarding what
                  payment, if any, shall be made to you upon the sale of WDS
                  except as may be set forth in a written agreement between the
                  parties or contained in written benefit plans available to
                  employees or executives generally.
