"PRINCE GEORGE'S County hereby unconditionally guarantees
to the holder of this bond that the covenants and agreements of The
Maryland-National Capital Park and Planning Commission therein
contained or referred to will be performed and fulfilled in accord-
ance with their terms."

Each such guaranty shall be endorsed on behalf of the appropriate
county in the manner prescribed in this Section for the guaranty of
the Commission's general obligation bonds.

The principal of and interest on any revenue bonds issued under
this Subsection shall be exempt from taxation in the State of Mary-
land as provided in Sections 70-58 and 59-52, respectively, of the
Codes of Montgomery and Prince George's County.

Nothing herein contained shall be construed to prevent the Com-
mission from voluntarily applying to the payment of the principal of
and interest on any revenue bonds issued under this Subsection,
either upon maturity or redemption, its general funds not otherwise
committed. This authority shall be deemed to include the power to
retire an entire issue of revenue bonds from the proceeds of general
obligation refunding bonds issued by the Commission pursuant to
the authority of Sections 70-59 and 59-53, respectively, of the Codes
of Montgomery and Prince George's County. Upon the retirement
of an issue of revenue bonds from the revenues of the facility, or
group of facilities, financed thereby, from other funds of the Com-
mission, or by refunding as herein authorized, the Commission may
elect to continue to charge for the use or enjoyment of any such
facility, or group of facilities, and may apply the revenues so de-
rived to any other function, purpose or objective of the Commission.

The Commission is hereby authorized and empowered to adopt
and, from time to time, amend, reasonable rules and regulations for
the use and enjoyment by the general public of any facility, or group
of facilities, financed under this Subsection. No such rules and regu-
lations shall be so drawn as to exclude any person tendering the
required fee or charge for such use and enjoyment because of race,
creed or color of such person. Any lease of any such facility, or group
of facilities, by the Commission shall contain appropriate and en-
forceable covenants by the lessee to comply with this limitation.

Sec. 2. And be it further enacted, That this Act shall take effect
July 1, 1971. JANUARY 1, 1972.

Approved May 17, 1971.
