charges, or income, revenues and receipts, and to require the Au-
thority to carry out any of its covenants and agreements with the
bondholders, and to perform its and their duties under this Act;
provided, however, that nothing in this section or any other section
of this Act shall authorize any receiver appointed pursuant to this
Act, for the purpose of operating and maintaining any project or
projects of the Authority, to sell, assign, mortgage or otherwise dis-
pose of, any of the assets of whatever kind and character belonging
to the Authority. It is the intention of this Act to limit the powers
of such receiver to the operation and maintenance of the facilities
of the Authority as the court shall direct, and no holder of bonds
of the Authority, nor any trustee, shall ever have the right in any
suit, action or proceedings at law or in equity to compel a receiver,
nor shall any receiver ever be authorized, or any court be empowered
to direct the receiver, to sell, assign, mortgage, or otherwise dispose of
any assets of whatever kind or character belonging to the Authority.

437. (Award of Contracts.) If any project or any portion thereof
or any improvement thereof shall be constructed, equipped or fur-
nished pursuant to a contract and the estimated cost thereof exceeds
Five Hundred Dollars ($500), such contract shall be awarded to the
lowest responsible bidder after advertisement for bids. The Au-
thority may make rules and regulations for the submission of bids
and the construction, equipping, furnishing and improvement of any
project or portion thereof. No contract shall be entered into for
construction, equipping, furnishing or improvement of any project,
or portion thereof, or for the purchase of materials, unless the con-
tractor shall give an undertaking with a sufficient surety or sureties
approved by the Authority, and in an amount fixed by the Authority,
for the faithful performance of the contract; and such contract shall
be accompanied by an additional bond for the protection of those to
furnish labor and material. All construction contracts shall provide,
among other things, that the person or corporation entering into such
contract with the Authority will pay for all materials furnished and
services rendered for the performance of the contract, and that any
person or corporation furnishing such materials or rendering such
services may maintain an action to recover for the same against the
obligor in the undertaking as though such person or corporation was
named therein, provided the action is brought within three (S) years
after the cause of action accrued. Nothing in this section shall be
construed to limit the power of the Authority to construct any project,
or portion thereof, or any addition, betterment, or extension thereto,
direct by the officers, agents, and employees of the Authority, or by
agreement with the Federal and State governments, or any agency or
department of either. Subject to the aforesaid, the Authority may
(but without intending by this provision to limit any powers of such
Authority) enter into and carry out such contracts, or establish or
comply with such rules and regulations concerning labor and ma-
terials and other related matters in connection with any project, or
portion thereof as the Authority may deem desirable, or as may be
requested by any Federal agency that may assist in the financing of
such project or any part thereof.

438. (Deposit and Audit of Funds.) Unless otherwise provided in
the resolution authorizing any issue of bonds under this Act, or un-
