is hereby authorized to enter into a Supplemental Agreement with
the Trustee, supplemental to the Trust Agreement, and shall deter-
mine thereby for what period or periods of time the said tolls and
revenues from the new bridge shall be paid over to the Trustee as
aforesaid, and when such determination shall have been made by
the Commission and incorporated in such Supplemental Agreement
such determination shall not be changed by the Commission or by
the State of Maryland or any agency or instrumentality thereof, but
shall continue in accordance with the provisions of such Supple-
mental Agreement. Such Supplemental Agreement, if entered into,
shall provide, among other matters, (a) for the payment of the tolls
and revenues from the bridge to be constructed under the provisions
of this subtitle to the Trustee under the Trust Agreement as herein-
before provided, (b) for setting forth the determination of the Com-
mission as to the period or periods during which such payment shall
be made, and (c) for directing the Trustee in the collection, holding
and disbursements of the toll revenues so to be paid over to it. And
whenever it shall happen that under the terms of such Supplemental
Agreement it is not necessary that the Commission pay such tolls
and revenues from the above-mentioned bridge to the Trustee as
aforesaid, then such tolls and revenues shall be paid into the Revenue
Fund account of the said Commission with reference to such new
bridge and the tolls shall remain in effect for such bridge and shall
continue to be collected by the Commission and disbursed by it in
accordance with the provisions of the resolution or trust agreement
authorized by Section 12GB. of this subtitle and as provided by law.

any bonds issued under the provisions of this subtitle may be secured
by a trust agreement by and between the Commission and a cor-
porate trustee, which may be any trust company or bank having the
powers of a trust company within or without the State. Such trust
agreement or the resolution providing for the issuance of such bonds
may pledge or assign the tolls and other revenues to be received, but
shall not convey or mortgage the Expressway or any part thereof.

reference to the agreement supplemental to the Trust Agreement,
dated as of October 1, 1954, between the Commission and the

Agreement with respect to the assignment of the tolls and revenues
from the bridge to be constructed under the provisions of this sub-
title to said Fidelity-Baltimore National Bank & Trust Company,
Trustee under said Trust Agreement, dated as of October 1, 1954.
Such trust agreement or resolution providing for the issuance of
such bonds may contain such 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 Commission in relation to the acquisition of
property and the construction, improvement, maintenance, repair,
operations and insurance of the Expressway, the rates of toll to be
charged, and the custody, safeguarding and application of all moneys.
It shall be lawful for any bank or trust company incorporated under
the laws of the State which may act as depositary of the proceeds
