      (d) No Conflicts. Neither the execution and delivery of this Amendment,
the Consent or the Credit Agreement (as modified hereby), nor the consummation
of the transactions contemplated hereby and thereby, nor the performance of and
compliance with the terms and provisions hereof or thereof by any Loan Party
will, at the time of such performance, (a) violate or conflict with any
provision of its articles or certificate of incorporation or bylaws or other
organizational or governing documents of such Person, (b) violate, contravene or
materially conflict with any Requirement of Law or any other law, regulation

judgment, injunction, decree or permit applicable to it, except for any
violation, contravention or conflict which could not reasonably be expected to
have a Material Adverse Effect, (c) (i) violate, contravene or conflict with the
contractual provisions of, or cause an event of default under, any Loan Document

cause an event of default under, any other loan agreement, indenture, mortgage,
deed of trust, contract or other agreement or instrument to which it is a party
or by which it may be bound or (d) result in or require the creation of any Lien
(other than those contemplated in or created in connection with the Loan
Documents) upon or with respect to its properties. No consent or authorization
of, filing with, notice to or other act by or in respect of, any Governmental
Authority or any other Person is required in connection with the transactions
contemplated hereby.

      (e) No Default. Both before and after giving effect to this Amendment and
the transactions contemplated hereby, no event has occurred and is continuing
that constitutes a Default or Event of Default.

generality of the foregoing, the Security Documents and all of the Collateral
described therein do and shall continue to secure the payment of all Obligations
under and as defined therein, in each case as modified hereby.

remedy of any Secured Party under any of the Loan Documents, nor, except as
