"Level II Pricing" applies on any day on which (i) the Borrower's long-term debt is rated A or higher by S&P or A2 or higher by Moody's and (ii) Level I Pricing does not apply. "Level III Pricing" applies on any day on which (i) the Borrower's long-term debt is rated A- or higher by S&P or A3 or higher by Moody's and (ii) neither Level I Pricing nor Level II Pricing applies. "Level IV Pricing" applies on any day on which (i) the Borrower's long-term debt is rated BBB+ or higher by S&P and/or Baa1 or higher by Moody's and (ii) none of Level I Pricing, Level II Pricing and Level III Pricing applies. "Level V Pricing" applies on any day on which (i) the Borrower's long-term debt is rated BBB or higher by S&P or Baa2 or higher by Moody's and (ii) none of Level I Pricing, Level II Pricing, Level III Pricing and Level IV Pricing applies. "Level VI Pricing" applies on any day if no other Pricing Level applies on such day. "Moody's" means Moody's Investors Service, Inc. 12 "Pricing Level" refers to the determination of which of Level I, Level II, Level III, Level IV, Level V or Level VI Pricing applies on any day. "S&P" means Standard & Poor's Ratings Services, a division of The McGraw-Hill Companies, Inc. The "Usage" applicable to any date is the percentage equivalent of a fraction the numerator of which is the sum of the aggregate outstanding principal amount of the Advances at such date and the denominator of which is the aggregate amount of the WC Commitments at such date. If for any reason any Advances remain outstanding following the termination of the WC Commitments, Usage will be deemed to be more than 33%. The credit ratings to be utilized for purposes of this Schedule are those assigned to the senior unsecured long-term debt securities of the Parent without third-party credit enhancement, and any rating assigned to any other debt security of the Parent shall be disregarded. The ratings in effect for any day are those in effect at the close of business on such day. In the case of split ratings from S&P and Moody's, the rating to be used to determine the applicable Pricing Level is the higher of the two (e.g., A+/A2 results in Level I Pricing); provided that if the split is more than one full rating category, the intermediate (or higher of the two intermediate ratings) will be used (e.g. A+/A3 results in Level II Pricing and AA-/A3 results in Level I Pricing); and provided further that unless the Parent's credit ratings qualify for at least Level V Pricing, no better Pricing Level will be applicable. 13 COMMITMENT SCHEDULE =============================================================================== Lender Commitment =============================================================================== JPMorgan Chase Bank $66,000,000 - ------------------------------------------------------------------------------- Barclays Bank PLC $55,000,000 - ------------------------------------------------------------------------------- Bank of America, N.A. $55,000,000 - ------------------------------------------------------------------------------- Citibank, N.A. $55,000,000 - ------------------------------------------------------------------------------- Fleet National Bank $55,000,000 - ------------------------------------------------------------------------------- Lloyds TSB Bank plc $55,000,000 - ------------------------------------------------------------------------------- Wachovia Bank, National Association $50,000,000 - ------------------------------------------------------------------------------- Credit Lyonnais New York Branch $50,000,000 - ------------------------------------------------------------------------------- Commerzbank Aktiengesellschaft, New York and $50,000,000 Grand Cayman Branches - ------------------------------------------------------------------------------- Deutsche Bank AG, New York Branch $50,000,000 - ------------------------------------------------------------------------------- HSBC Bank USA $37,000,000 - ------------------------------------------------------------------------------- Mellon Bank, N.A. $37,000,000 - ------------------------------------------------------------------------------- Royal Bank of Canada $37,000,000 - ------------------------------------------------------------------------------- ABN AMRO Bank N.V. $37,000,000 - ------------------------------------------------------------------------------- Comerica Bank $37,000,000 - ------------------------------------------------------------------------------- State Street Bank and Trust Company $37,000,000 - ------------------------------------------------------------------------------- Bank of Tokyo-Mitsubishi, Limited $37,000,000 - ------------------------------------------------------------------------------- The Bank of New York $0.00 - ------------------------------------------------------------------------------- Bank One, N.A. $0.00 - ------------------------------------------------------------------------------- Total $800,000,000 =============================================================================== 14
