        discount and without interest cost to the qualified issuer. The 
        applicable credit rate with respect to any qualified tax credit 
        bond shall be determined as of the first day on which there is 
        a binding, written contract for the sale or exchange of the

        case of a bond which is issued during the 3-month period ending 
        on a credit allowance date, the amount of the credit determined 
        under this subsection with respect to such credit allowance 
        date shall be a ratable portion of the credit otherwise 
        determined based on the portion of the 3-month period during

                defined in section 26(b)) plus the tax imposed by
