obligations from any interest rate, currency or commodity swap agreement, interest rate cap or collar agreement, or other agreement or arrangement designated to protect a Person against fluctuation in interest rates, currency exchange rates or

Notwithstanding anything to the contrary in the foregoing, any Permitted Call Spread Agreement shall not constitute a Contingent Obligation of any Person. 

“Indebtedness” is (a) indebtedness for borrowed money or the deferred price of property or services, such
as reimbursement and other obligations for surety bonds and letters of credit, (b) obligations evidenced by notes, bonds, debentures or similar instruments, (c) capital lease obligations, and (d) Contingent Obligations.

of each such call option transaction are customary for agreements of such type, as determined by Borrower in good faith, and (ii) the purchase price for such Bond Hedge Transaction, less the proceeds received by the Borrower from the sale of

upon the occurrence of a “fundamental change”, (iii) Borrower’s market capitalization, as of the close of the regular trading session for the Borrower’s common stock on the date of the pricing of such Indebtedness, is not less
