Such funds may be applied by the state, without appropriation, solely for the purposes of paying the principal or purchase price of, redemption premium, if any, and interest on such bonds in the fiscal year in which such funds are received, or in any subsequent fiscal year, as such amounts come due or may be paid or deemed paid prior to maturity in accordance with their terms and further satisfying the terms of any trust or security agreement or resolution entered into in accordance with RSA 228-A:3 or credit facility entered into in accordance with RSA 228-A:4.
