(2) A port district or port development authority may pledge as security for any bond, note, or other evidence of indebtedness, or for any obligation to repay or reimburse the guarantor of a bond, note, or evidence of indebtedness, its right, title, and interest to or in the following:
(a) Any federal grant or payment received by the port district or port development authority, or that may be received in the future;

(c) If any bond, note, other evidence of indebtedness, or related agreement complies with subsection (4) of this section, then any of the funds held by a trustee or custodian, or by a port development authority, do not constitute public moneys or funds of a port district, and must be kept segregated and set apart from other funds at all times.
(4)(a) If a port development authority loans or grants federal or private funds to a private party, or uses federal or private funds to guarantee any obligations of a private party, then any bond, note, or other evidence of indebtedness issued or entered into for the purpose of receiving the federal or private funds, or any agreement to repay or reimburse guarantors, are not obligations of a port district. These obligations may be paid only from:
(i) A special fund established in accordance with subsection (3) of this section;
(ii) Any security pledged in accordance with this section; or
(iii) Both (a)(i) and (ii) of this subsection (4).
(b) Any bond, note, or other evidence of indebtedness to which this subsection (4) applies must contain a recital establishing that the bond, note, or evidence of indebtedness is not an obligation of the port district or the state, and that neither the faith and credit, nor the taxing power of the state, any subdivision or agency of the state, or any port district is pledged to pay the principal, interest, or premium, if any, on the bond, note, or evidence of indebtedness.
(c) Any bond, note, other evidence of indebtedness, or other obligation to which this subsection (4) applies may not be included in any computation for purposes of limitations on indebtedness.
