the Trustee or any Paying Agent from any loss that any of them may suffer if such Security is replaced. The Company may charge such Holder for the Company's expenses in replacing such Security and the

fide purchaser in whose hands such Security is a legal, valid and binding obligation of the Company.

consent or any amendment, modification or other change to this Indenture, Securities owned by the Company or an Affiliate of the Company shall be disregarded as though they were not outstanding,

Notes include those stated in this Note, the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S. Code
§§ 77aaa-77bbbb), as amended from time to time. The Senior Notes are subject to all such-terms, and Holders are referred to the Indenture and
such Act for a statement of them. Capitalized and certain other terms used herein and not otherwise defined have the meanings set forth in the Indenture. The Senior Notes are unsecured obligations of
the Company limited in aggregate principal amount to $100,000,000.

The
Indenture limits, among other things, the incurrence of Indebtedness by the Company-and its Subsidiaries; the creation of Liens by the Company and its Subsidiaries;

denominations of $1,000 and integral multiples of $1,000. A Holder may transfer or exchange Senior Notes in accordance with the Indenture. The Registrar may require a Holder, among other things, to
furnish appropriate endorsements and transfer documents and to pay to it any taxes and fees required by law or permitted by the Indenture.

7.Persons Deemed Owners.  The registered Holder of a Senior Note may be treated as the owner of it for
all purposes.

8.Unclaimed Money.  If money for the payment of principal or interest remains unclaimed for two years,
the Trustee or Paying Agent will pay the money back to the Company at its request. After that, Holders entitled to the money must look to the Company for payment as general creditors unless an
"abandoned property" law designates another Person.

9.Amendment, Supplement, Waiver.  The Company and the Trustee may, without the consent of the Holders
of any outstanding Senior-Notes, amend, waive or supplement the Indenture or the Senior Notes for certain specified purposes, including, among other things, curing ambiguities, defects or
inconsistencies, maintaining the qualification of the Indenture under the Trust Indenture Act of 1939, as amended, or making any change that does not adversely affect the rights of any Holder. Other
amendments and modifications of the Indenture or the Senior Notes may be made by the Company and the Trustee with the consent of the Holders of not less than a majority of the aggregate principal
amount of the-outstanding Senior Notes, subject to certain exceptions requiring the consent of the Holders of the particular Senior Notes to be affected.

10.Successor Corporation.  When a successor corporation assumes all the obligations of its predecessor
under the Senior Notes and the Indenture and the transaction complies with the terms of Article V of the Indenture, the predecessor corporation will be released from those obligations.

11.Defaults and Remedies.  Events of Default are set forth in the Indenture. Subject to certain
limitations in the Indenture, if an Event of Default (other than an Event of Default specified in Section 6.1(a) (vi) or (vii) of the Indenture) occurs with respect to. the
Company and is continuing, then the Holders of not less than 25% in aggregate principal :amount of the outstanding Senior Notes may, and the Trustee upon the written request of the Holders of not less
than 25% in aggregate principal amount of the outstanding Senior Notes shall, declare the principal of and interest on all of the Senior Notes to be due and payable immediately. If an Event of Default
specified in Section 6.l(a)(vi) or (vii) of the Indenture occurs with respect to the Company and is continuing, the principal of and interest on all of the Senior Notes shall ipso
facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. Holders may not enforce the Indenture or the Senior Notes except as
provided in the Indenture. The Trustee may require indemnity satisfactory to it before it enforces the Indenture or the Senior Notes. Subject to certain limitations, Holders of a majority in principal
amount of the then outstanding Senior Notes may direct the Trustee in writing in its exercise of any trust or power. The Trustee may withhold from Holders notice of any continuing default (except a
default in payment of principal or interest) if it determines that withholding notice is in their interests.

12.Trustee Dealings with Company.  The Trustee, in its individual or any other capacity, may make loans
to, accept deposits from, and perform services for the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates as if it were not Trustee.

13.No Recourse Against Others.  A director, officer, employee or stockholder, as such, of the Company
shall not have any liability for any obligations of the Company under the Senior Notes or the Indenture or for any claim based on, in respect of, or by reason of, such obligations or-their
creation. Each Holder by accepting a Senior Note waives- and releases all such liability. The waiver and release are part of the consideration for the issue of the Senior Notes.

obligations pursuant to certain sections thereof, subject to the terms of the Indenture, upon the payment of all the Senior Notes or upon the irrevocable deposit with the Trustee of money or U.S.
