         amended by deleting Section 5.10(a) in its entirety and replacing it
         with the following:

                           "(a)     Domestic Subsidiaries. In the event that any
         Person becomes a Domestic Subsidiary of the Company (other than a

         joinder agreement in form and substance reasonably acceptable to each
         Agent, directly by as well as complying with (ii) above; provided,
         further, that notwithstanding any of the foregoing to the contrary, any

         hereunder and a Grantor under the Pledge and Security Agreement by
         executing and delivering to the Administrative Agent and Collateral
         Agent a Counterpart Agreement."
