The authorizing issuer and the project county are authorized and empowered to enter into an intergovernmental loan agreement to facilitate the financing of hospital facilities. An intergovernmental loan agreement obligates the project county to make payments to or on account of the authorizing issuer from payments received under one or more subsidiary loan agreements. The intergovernmental loan agreement is a limited obligation of the project county payable solely from the revenues derived under one or more subsidiary loan agreements. The intergovernmental loan agreement does not constitute an indebtedness of the project county within the meaning of any state constitutional provision or statutory limitation and does not constitute nor give rise to a pecuniary liability of the project county or a charge against its general credit or taxing powers, and this fact must be plainly stated in the intergovernmental loan agreement.
