          A.   COVENANTS AND AGREEMENTS OF THE COMPANY.

               a.   The Company hereby agrees that, notwithstanding the fact 
that the 1998 Repurchases pursuant to the 1998 Plan may result in the 
Shareholder Event, if the Shareholder Event should occur solely by virtue of 
the 1997 Plan Repurchases and/or the 1998 Repurchases pursuant to the 1998 
Plan, such Shareholder Event shall be deemed not to have occurred, and the 
Company hereby grants a limited waiver of any provision of the Rights

considered to have occurred solely by virtue of the 1997 Plan Repurchases and 
the 1998 Repurchases pursuant to the 1998 Plan.

               b.   The Company hereby acknowledges and agrees that, by 
virtue of the operation of this Agreement, the Shareholder, alone or together 
with its Affiliates and Associates, may have Beneficial Ownership of twenty 
percent (20%) or more of the shares of Common Stock of the Company then 
outstanding, provided that such circumstance occurs solely as a result of the 
1997 Plan Repurchases and the 1998 Repurchases pursuant to the 1998 Plan, and 
yet not be deemed to be an "Acquiring Person" for purposes of the Rights 
Agreement.

               c.   The Company acknowledges and agrees that nothing in this

purchases of the Common Stock so long as the Current Shareholder Position is

exercising the voting privileges commensurate with its ownership of the 
Common Stock. 

          B.   COVENANTS AND AGREEMENTS OF THE SHAREHOLDER.

               a.   The Shareholder agrees that neither the Shareholder nor 
any of its Affiliates shall engage in any Prohibited Activity (i) at any time 
that the Shareholder, alone or together with its Affiliates has Beneficial 
Ownership of 20% or more of the outstanding Common Stock of the Company as a 
result of Repurchases pursuant to the Plan, or (ii) during the Standstill 
Period.

               b.   The Shareholder acknowledges and agrees that this 
Agreement constitutes only a limited waiver of the Rights Agreement and that 
the waiver herein contained applies only to the occurrence of the Shareholder 
Event as the result solely of the 1997 Plan Repurchases and the 1998 
Repurchases pursuant to the 1998 Plan and not to any other circumstances or 
conditions which may result in the occurrence of the Shareholder Event.

               c.   The Shareholder hereby further acknowledges that, should 
the Shareholder Event occur as a result of or in connection with the purchase 
or acquisition by the Shareholder of Common Stock of the Company which 
results in an increase in the Current Shareholder Position, then this limited 
waiver shall not apply and the Shareholder shall, in accordance with the 
terms of the Rights Agreement, be deemed to be an "Acquiring Person."

          C.   COVENANTS AND AGREEMENTS OF THE COMPANY AND THE SHAREHOLDER.

               The Company and the Shareholder acknowledge and agree that 
this Agreement constitutes a limited waiver of the Rights Agreement; by 
agreeing to this waiver, the Company has not agreed to waive any other 
provisions of the Rights Agreement and the Company hereby expressly reserves 
its right fully to enforce the Rights Agreement except as such enforcement 
may be limited by the express terms of this Agreement.

     4.   GENERAL PROVISIONS. 

          A.   VOIDABILITY.  This Agreement shall become null and void if the
