1.             Glenn Kaufman shall constitute the Additional Director in accordance with Section 1(c) of the Agreement.  The parties hereby agree that Mr. Kaufman will serve as a Class II director, rather than a Class III director, as originally contemplated by Section 1(c) of the Agreement.

3.             Except as specifically set forth herein, the parties continue to be bound by the terms and conditions of the Agreement.  This letter agreement may be executed by the parties in counterparts, all of which will be deemed an original instrument, but together will constitute one and the same instrument.  The parties may execute this letter agreement by facsimile or

If you are in agreement with the foregoing, please so indicate by executing this letter agreement below.
