of the Company (herein called the "Securities"), issued and to be issued in one or more series under the Indenture, and
reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities
thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are
to be, authenticated and delivered. This Security is one of the series designated on the face hereof, limited in aggregate principal
amount to $6,508,000.


 


The Company shall not be entitled to redeem the Securities prior
to the maturity of the Securities.


 


If a Change of Control shall occur, Holders of the Securities
will have the right to require the Company to redeem such Holder's Securities, in whole or in part, in integral multiples of $1,000,
at a Redemption Price equal to 101.00% of the principal amount thereof and unpaid interest, if any, to the Redemption Date, all
as provided in the Indenture.


 


In the event of redemption of this Security in part only, a
new Security or Securities of this series and of like tenor for the unredeemed portion hereof will be issued in the name of the
Holder hereof upon the cancellation hereof.


 


The Indenture contains provisions for defeasance at any time
of the entire indebtedness of this Security or certain restrictive covenants and Events of Default with respect to this Security,
in each case upon compliance with certain conditions set forth in the Indenture.


 


If an Event of Default with respect to Securities of this series
shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and
with the effect provided in the Indenture.


 


The Indenture permits, with certain exceptions as therein provided,
the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities
of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of
66-2/3% in principal amount of the Securities at the time Outstanding of each series to be affected. The Indenture also contains
provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding,
on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture
and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security
shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is
made upon this Security.


 


As provided in and subject to the provisions of the Indenture,
the Holder of this Security shall not have the right to institute any proceeding with respect to the Indenture or for the appointment
of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written

amount of the Securities of this series at the time Outstanding shall have made written request to the Trustee to institute proceedings
in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity, and the Trustee shall not have received
from the Holders of a majority in principal amount of Securities of this series at the time Outstanding a direction inconsistent
with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and
offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of
any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein.


 






    	 



    	 



    

 


No reference herein to the Indenture and no provision of this
Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the
principal of and any premium and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed.


 


As provided in the Indenture and subject to certain limitations
therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration

are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security
Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities
of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the
designated transferee or transferees.


 


The Securities of this series are issuable only in registered
form without coupons in denominations of $1,000 and any integral multiple thereof. As provided in the Indenture and subject to
certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities
of this series and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.


 


No service charge shall be made for any such registration of
transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable
in connection therewith.


 


Prior to due presentment of this Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security
is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee
