Ms. Enid Tanenhaus


Dear Enid:

Because of your value to the Company as a whole, I am pleased to offer you a
special deferral bonus of $150,000 to be paid as follows: the first payment,
$50,000 less applicable withholding taxes, will be paid in the next payroll
period following you signing the agreement. Each of the two subsequent payments
will be made in August of 2003 and 2004. This special deferral bonus will be
subject to the following conditions:

1.   If the Company terminates you involuntarily for Convenience prior to August
     2005, it will pay you the unpaid portion of the special bonus immediately
     following the termination. In return you agree to abide by the Covenants
     from the date of your termination of employment with the Company. (All
     capitalized terms are defined on Attachment A.)

2.   If the Company terminates your employment involuntarily for Performance
     prior to August, 2005, it will not pay you any portion of the special
     bonuses remaining unpaid at the time of termination, and you agree to be
     bound by the Covenants from the date of your termination of employment with
     the Company.

3.   If you decide to terminate your employment voluntarily with the Company
     prior to August, 2005, or if you are terminated involuntarily for Cause,
     the Company will not pay you any portion of the special bonuses remaining
     unpaid at the time of termination, and you agree to repay the gross amount
     of any deferral bonus amounts already paid to you within the 12 month
     period prior to your termination date. You also agree to be bound by the
     Covenants following the date of your termination of employment with the
     Company.

Any payment made under the terms of this letter will require that you agree to
and sign a General Release and Settlement Agreement provided by the Company.

All other terms and conditions of your current employment with Company shall
remain in effect. Neither this document nor any other Company procedures and
communications are intended to be interpreted as a promise or guarantee of
future or continued employment. Nothing in this letter shall detract from your
right (and the Company's right) to end the employment relationship at any time.

Very truly yours,

James R. Lewis

Agreed:
