(b)  Notwithstanding any other provision of this Article or any
recitals in any bonds issued hereunder, all such bonds shall be
deemed to be negotiable instruments under the laws of this State.

(c)   The bonds may be issued in coupon or in registered form or
both, and provision may be made for the registration of any coupon
bonds as to principal alone and also as to both principal and interest,
for the reconversion into coupon bonds of any bonds registered as to
both principal and interest, and for the interchange of coupon and
registered bonds. Provision may also be made for the replacement
of bonds which become mutilated or are lost or destroyed.

(d)  The bonds shall be exempt from the provisions of Sections 9,
10, and 11 of Article 31 of the Annotated Code of Maryland, and the
Service may sell such bonds in such manner, either at public or at
private sale, and for such price as it may determine.

the consent of any department, division, commission, board, bureau
or agency of the State, and without any other proceedings or the
happening of any other conditions or things than those specifically
required hereunder.

13. Additional bonds.

If the proceeds of the bonds of any issue shall, by reason of in-

authorized, additional bonds may in like manner be issued to provide
the amount of such deficiency and shall be deemed to be of the same
issue and shall be entitled to payment from the same fund without
preference or priority of the bonds first issued. If the proceeds of
such bonds shall exceed the amount so required, such excess shall be
deposited to the credit of any reserve fund for such bonds or, if so
provided in the trust agreement securing such bonds, may be applied
to the cost of any additional project.

tion premium thereon and any interest accrued or to accrue to the
date of redemption of such bonds, and, if deemed advisable by the
Board of Directors, for either or both of the following combined
additional purposes: (i) constructing improvements or extensions to
or enlargements of any existing project or projects and (ii) paying
all or any part of the cost of any additional project or projects. The
issuance of such bonds and the details thereof, the rights of the
holders thereof, and the rights, duties and obligations of the Service
in respect thereto, shall be governed by the provisions of this Article
relating to revenue bonds, in so far as the same may be applicable.
