(c) In connection with the issuance of its Bonds, the Authority may enter into arrangements to provide additional security and liquidity for the Bonds. These may include, without limitation, municipal bond insurance, letters of credit, lines of credit by which the Authority may borrow funds to pay or redeem its Bonds and purchase or remarketing arrangements for assuring the ability of owners of the Authority's Bonds to sell or to have redeemed their Bonds. The Authority may enter into contracts and may agree to pay fees to persons providing such arrangements, including from Bond proceeds but only under circumstances in which the total interest paid or to be paid on the Bonds, together with the fees for the arrangements (being treated as if interest), would not, taken together, cause the Bonds to bear interest, calculated to their absolute maturity, at a rate in excess of the maximum rate allowed by law. The resolution of the Authority authorizing the issuance of its Bonds may provide that interest rates may vary from time to time depending upon criteria established by the Authority, which may include, without limitation, a variation in interest rates as may be necessary to cause Bonds to be remarketable from time to time at a price equal to their principal amount, and may provide for appointment of a national banking association, bank, trust company, investment banker or other financial institution to serve as a remarketing agent in that connection. The resolution of the Authority authorizing the issuance of its Bonds may provide that alternative interest rates or provisions will apply during such times as the Bonds are held by a person providing a letter of credit or other credit enhancement arrangement for those Bonds.
