Any issue of revenue bonds may be secured by a trust indenture by and between the Director, in the name of the Commonwealth, and a corporate trustee, which may be any trust company or bank having the powers of a trust company. The trust indenture may pledge fees and charges to be received from the use of and for the services rendered by any camp and recreational facilities to be acquired or constructed from the proceeds of such revenue bonds, but no trust indenture shall convey or mortgage any camping or recreational facilities or any part thereof.

Either the resolution providing for the issuance of revenue bonds or the trust indenture may contain provisions for protecting and enforcing the rights and remedies of the bondholders as may be reasonable and proper and not in violation of law, including covenants setting forth the duties of the Director in relation to the acquisition, construction, improvement, maintenance, operation, repair and insurance of such facilities, and the custody, safeguarding and application of all moneys. The trust indenture may also provide that camping and recreational facilities shall be acquired, constructed, enlarged or improved, and paid for under the supervision and approval of consulting engineers employed or designated by the Director, in the name of the Commonwealth, and satisfactory to the original purchasers of the bonds issued. The trust indenture may further require that the security given by contractors and by any depository of the proceeds of the bonds or revenues of the camping and recreational facilities or other moneys pertaining to the facilities be satisfactory to the purchasers. It shall be lawful for any bank or trust company incorporated under the laws of this Commonwealth to act as depository and to furnish indemnifying bonds or to pledge securities required by the Director. Such indenture may set forth the rights and remedies of the bondholders and of the trustee, and may restrict the individual right of action of bondholders as is customary in trust indentures securing bonds and debentures of corporations.

In addition, the indenture may contain other provisions that the Director deems reasonable and proper for the security of the bondholders.
