THEODORE R. McKELDIN, GOVERNOR                     169

this Act shall not directly, indirectly or contingently obligate or em-
power the County Commissioners of Baltimore County to levy or
pledge any form of taxation whatever therefor or to make any appro-
priation for their payment.

434. (Trust Indenture.) The Authority is hereby authorized, in
its discretion, to secure any revenue bonds, certificates or other evi-
dence of indebtedness issued to provide funds for the purchase,
acquisition, construction or improvement of any project or projects
by a trust indenture by and between the Authority and a corporate
trustee, which may be any trust company or bank having the powers
of a trust company within or outside the State. At any one time,
the Authority may, in its discretion, be a party to one or more of
such trust indentures, if revenue bonds have been issued to finance
more than a single project as defined in this Act. Such trust indenture
or indentures may pledge or assign all revenues to be received from
any project or projects but shall not convey or mortgage the project
or any part thereof. Either the resolution providing for the issuance
of revenue bonds or such trust indenture or indentures may contain
such provisions for protecting and enforcing the rights and remedies
of the bondholders as may be reasonable and proper, not in violation
of law, including covenants setting forth the duties of the Authority
in relation to the construction, acquisition, improvement, installation,
maintenance, operation, repair and insurance of any project or
projects and the custody, safeguarding and application of all moneys,
and may provide that any project or projects shall be constructed
and paid for under the supervision and approval of consulting engi-
neers employed or designated by the Authority and satisfactory to
the trustee appointed as provided herein, and if none, the original
purchasers of the bonds issued hereunder. Such trust indenture or
indentures may further provide that the security given by contractors
and by any depositary of the proceeds of the bonds or revenues of
any project or other moneys pertaining thereto, be satisfactory to
the trustee appointed as provided herein, and if none, the original
purchasers of the bonds. It shall be lawful for any bank or trust
company incorporated under the laws of this State to act as depositary
of the proceeds of the bonds or revenues. Such resolution or such
trust indenture or indentures 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. All expenses incurred
in carrying out such trust indenture may be treated as a part of the
cost of maintenance, operation and repair of any project or projects.

i35. (Revenues.) The Authority is hereby authorized and empow-
ered to fix and to revise from time to time rates, tolls, rentals and
charges for the use of any of its projects, and to impose, charge and
collect the same, and to contract with any person, partnership, asso-
ciation or corporation desiring the use of any of its projects, either
in whole or in part, and to fix the terms, conditions and rates of
charges for such use.

Such rates, tolls, rentals or charges shall be so fixed and adjusted
as to provide a fund sufficient to pay (a) the cost of maintaining,
preparing and operating the project or projects from which such
rates, tolls, rentals and charges are received, including reserves for
