services and supplies necessary for the study authorized by this Act,
and all other contracts and agreements requiring payment of money
from said account or accounts shall be in writing and shall be
executed by the County Commissioners of Frederick County.

Sec. 5. And be it further enacted, That the bonds hereby author-
ized shall constitute, and they shall so recite, an irrevocable pledge
of the full faith and credit and unlimited taxing power of the County
to the payment of the maturing principal and interest of such bonds
as and when the same respectively mature. In each and every fiscal
year that any of said bonds are outstanding, the County shall levy
or cause to be levied ad valorem taxes upon all the assessable property
within the corporate limits of the County in rate and amount sufficient
to provide for the payment, when due, of the interest and principal
of all said bonds maturing in each such fiscal year and in the event
the proceeds from the taxes so levied in any such fiscal year shall
prove inadequate for the above purposes, additional taxes shall be
levied in the succeeding fiscal year to make up any such deficiency.
The County may apply to the payment of principal and interest of
any bonds issued hereunder any funds received by it from the State
of Maryland, the United States of America, any agency or instru-
mentality thereof, or from any other source, if such funds are granted

and to the extent of any such funds received or receivable in any
fiscal year the taxes hereby required to be levied may be reduced
proportionately.

dependent upon or related to the validity or invalidity of the obliga-
tions so refunded. The powers herein granted with respect to the
issuance of bonds, and also the limitations herein on such powers
shall be applicable to the issuance of refunding bonds. Said refunding
bonds may be issued by the County for the purpose of providing it
with funds to purchase in the open market any of its outstanding
bonds issued hereunder, prior to the maturity thereof, or for the
purpose of providing it with funds for the redemption prior to
maturity of any outstanding bonds issued hereunder which are, by
their terms redeemable. The resolution authorizing the issue of any
such refunding bonds shall describe the issue or issues of bonds of
the County so to be refunded, and no issue of such refunding bonds
shall exceed in amount the par amount of such bonds so described in
said resolution. No such refunding bonds shall actually be delivered
to the purchaser or purchasers thereof more than six (6) months in
advance of redemption date or dates of bonds to be redeemed and
refunded and the proceeds of the sale of any such refunding bonds
shall be segregated and set apart by the County as a separate trust
fund to be used solely for the purpose of paying the purchase or
redemption prices of the bonds to be refunded.

the bonds authorized hereby, the County may, prior to the prepara-
