Ind. Code § 36-10-10-22
In the discretion of the board, the bonds may be secured by a trust indenture between the authority and a corporate trustee, which may be any trust company or national or state bank within Indiana having trust powers. The trust indenture may mortgage all or part of the land, convention center, or both for which the bonds are issued. The trust indenture may contain the provisions for protecting and enforcing the rights and remedies of the bondholders that are reasonable and proper, including covenants setting forth the duties of the authority and board in relation to the construction of the convention center, its insurance, and the custody, safeguarding, and application of all money received or to be received by the authority due to the convention center financed by the issuance of the bonds. The indenture may set forth the rights and remedies of the bondholders and trustee and provisions restricting the individual right of action of bondholders. Within the limits of this chapter, the board may provide by resolution or in the trust indenture for the payment of the proceeds of the sale of the bonds to an officer, board, or depository as it determines for the custody of them and for the method of disbursement, with safeguards and restrictions that it determines.
