by reason of taking or continuing to take any such action. The Agent shall in
all cases be fully protected in acting or in refraining from acting, under this
Agreement in accordance with a request of the Lenders (or to the extent

any action taken or failure to act pursuant thereto shall be binding upon all
the Lenders.

        10.05 Notice of Default. The Agent shall not be deemed to have knowledge
of the occurrence of any Default or Event of Default, other than a default in

describing such Default or Event of Default and stating that such notice is a
"notice of default". In the event that an agent receives such a notice, such
agent shall give prompt notice thereof to the Lenders. Such agent shall take
such action with respect to such Default or Event of Default as shall be
reasonably directed by the Lenders, provided that, unless and until such agent
shall have received such directions, such agent may (but shall not be obligated
to) take such action, or refrain from taking such action, with respect to such
Default or Event of Default as it shall deem advisable in the best interests of
the Lenders.

neither the Agent, officers, directors, employees, agents, attorneys-in-fact or
affiliates of any agent has made any representations or warranties to it and
that no act by any agent hereafter taken, including any review of the affairs of
the Borrower shall be deemed to constitute any representation or warranty by
such agent to any Lender. Each Lender represents to each agent that it has,
independently and without reliance upon any such agent or any other Lender, and
based on such documents and information as it has deemed appropriate, made its
own appraisal of and investigation into the business, assets, operations,
property, financial and other conditions, prospects and creditworthiness of the
Borrower and made its own decision to make its Loans hereunder and enter into
this Agreement and the other agreements contemplated hereby. Each Lender also
represents that it will, independently and without reliance upon any agent or
any other Lender, and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit analysis, appraisals
and decisions in taking or not taking action under this Agreement, and to make
such investigation as it deems necessary to inform itself as to the business,
assets, operations, property, financial and other conditions, prospects and

<PAGE>   26

furnished to the Lenders by any agent hereunder, no agent shall have any duty or
responsibility to provide any Lender with any credit or other information
concerning the business, operations, assets, property, financial and other
conditions, prospects or creditworthiness of the Borrower which may come into
the possession of any such agent or any of its officers, directors, employees,
agents, attorneys-in-fact or affiliates.

        10.07 Indemnification. The Lenders agree to indemnify the Agent in its
capacity as such, ratably according to their Commitments, from and against any
and all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, reasonable expenses or disbursements of any kind
whatsoever which may at any time (including, without limitation, at any time
following the payment of the Obligations) be imposed on, incurred by or asserted
against each such agent in its capacity as such in any way relating to or
arising out of this Agreement, or any documents contemplated by or referred to
herein or the transactions contemplated hereby or any action taken or omitted to
be taken by any such agent under or in connection with any of the foregoing, but
only to the extent that any of the foregoing is not paid by Borrower, provided
that no Lender shall be liable to the Agent for the payment of any portion of
such liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements resulting solely from any such agent's
gross negligence or willful misconduct. If any indemnity furnished to an agent
for any purpose shall, in the opinion of such agent, be insufficient or become
impaired, the agent may call for additional indemnity and cease, or not
commence, to do the acts indemnified against until such additional indemnity is
furnished. The agreements in this Section 10.07 shall survive the payment of all
Obligations.

be terminated, without any other or further act or deed on the part of such
former agent or any of the parties to this Agreement. After the retiring Agent's
resignation hereunder as Agent the provisions of this Section 10 shall inure to
its benefit as to any actions taken or omitted to be taken by it while it was
Agent under this Agreement.

        10.09 Resignation, Transfer by Agent.

                (a) An Agent may resign from the performance of all its
        functions and duties hereunder at any time by giving 45 Business Days'

        Section 10, Rothschild, as Agent, may transfer its rights and
