 whether under  the pricing and  other terms of  this Agreement or  under
 the terms  of any  other  purchasing or  pricing arrangements  that  may

 the Clients om certain of their subsidiaries or affiliates equal to  the
 Agreed Percentage  of the aggregate  gross charges of  all net sales  of
 the  Products to  the  Members  directly or  indirectly  from  Supplier,
 whether under  the pricing and  other terms of  this Agreement or  under
 the terms  of any  other  purchasing or  pricing arrangements  that  may
