Loans hereunder, Assignee shall pay to Assignor, on the Assignment Effective
Date, an amount in Dollars equal to Assignee's Percentage of the aggregate

         5. CREDIT DETERMINATION; LIMITATIONS ON ASSIGNOR'S LIABILITY. Assignee
represents and warrants to Assignor, Borrowers, Agent and the other Banks that

Writings are required to be performed by it as a Bank thereunder. It is
understood and agreed that the assignment and assumption hereunder are made
without recourse to Assignor and that Assignor makes no representation or
warranty of any kind to Assignee and shall not be responsible for (i) the due
execution, legality, validity, enforceability, genuineness, sufficiency or
collectability of the Credit Agreement or any Related Writing, (ii) any
representation, warranty or statement made in or in connection with the Credit
Agreement or any Related Writing, (iii) the financial condition or
creditworthiness of any Borrower or Guarantor, (iv) the performance of or
compliance with any of the terms or provisions of the Credit Agreement or any
Related Writing, (v) inspecting any of the property, books or records of any
Borrower, or (vi) the validity, enforceability, perfection, priority, condition,

Loans or Letters of Credit. Neither Assignor nor any of its affiliates,
officers, directors, employees, agents or attorneys shall be liable for any
mistake, error of judgment, or action taken or omitted to be taken in connection
with the Loans, the Letters of Credit, the Credit Agreement or the Related
Writings, except for its or their own bad faith or willful misconduct. Assignee
appoints Agent to take such action as agent on its behalf and to exercise such
powers under the Credit Agreement as are delegated to Agent by the terms
thereof.

         6. INDEMNITY. Assignee agrees to indemnify and hold Assignor harmless
against any and all losses, cost and expenses (including, without limitation,
attorneys' fees) and liabilities incurred

pursuant to Section 10.10A of the Credit Agreement, upon the acceptance and
