if any) and interest on the Outstanding Secured Obligations, including, when authenticated and delivered, the Series 2006 (P-8) Notes, to confirm the lien of the Indenture upon the
Trust Estate, including property purchased, constructed or otherwise acquired by the Company since the date of execution of the Original Indenture, to secure
performance of the covenants therein and herein contained, to declare the terms and conditions on which the Series 2006 (P-8) Notes are secured, and in consideration of the premises
thereof and hereof, the Company by these presents does grant, bargain, sell, alienate, remise, release, convey, assign, transfer, mortgage, hypothecate, pledge, set over and confirm to the Trustee,
and its successors and assigns in the trust created thereby and hereby, in trust, all property, rights, privileges and franchises (other than Excepted Property or Excludable Property) of the Company,
whether now owned or hereafter acquired, of the character described in the Granting Clauses of the Original Indenture, wherever located, including all such property, rights, privileges and franchises
acquired since the date of execution of the Original Indenture, including, without limitation, all property described in Exhibit A attached
hereto; subject to all exceptions, reservations and matters of the character referred to in the Indenture, and does grant a security interest therein for the purposes expressed herein and in the
Indenture subject in all cases to Sections 5.2 and 11.2 B of the Original Indenture, and to the rights of the Company under the Indenture including the rights set forth in
Article V thereof; but expressly excepting and excluding from the lien and operation of the Indenture all properties of the character specifically excepted as "Excepted Property" or "Excludable
Property" in the Indenture to the extent contemplated thereby. 


        PROVIDED, HOWEVER, that if, upon the occurrence of an Event of Default, the Trustee, or any separate trustee or co-trustee
appointed under Section 9.14 of the Original Indenture or any receiver appointed pursuant to statutory provision or order of court, shall have entered into possession of all or substantially
all of the Trust Estate, all the Excepted Property described or referred to in Paragraphs A through H, inclusive, of "Excepted Property" in the Original Indenture then owned or
thereafter acquired by the Company, shall immediately, and, in the case of any Excepted Property described or referred to in Paragraphs I, J, L, N and P of "Excepted Property" in the Original
Indenture (excluding the property described in Section 2 of Exhibit B in the Original Indenture) upon demand of the Trustee or such other
trustee or receiver, become subject to the lien of the Indenture to the extent permitted by law, and the Trustee or such other trustee or receiver may, to the extent permitted by law, at the same time
likewise take possession thereof, and whenever all Events of Default shall have been cured and the possession of all or substantially all of the Trust Estate shall have been restored to the Company,
such Excepted Property shall again be excepted and excluded from the lien of the Indenture to the extent and otherwise as hereinabove set forth and as set forth in the Indenture. 


        The
Company may, however, pursuant to the Granting Clause Third of the Original Indenture subject to the lien of the Indenture any Excepted Property or Excludable Property, whereupon the
same shall cease to be Excepted Property or Excludable Property. 


        TO HAVE AND TO HOLD all such property, rights, privileges and franchises hereby and hereafter (by a Supplemental Indenture or
otherwise) granted, bargained, sold, alienated, remised, released, conveyed, assigned, transferred, mortgaged, hypothecated, pledged, set over or confirmed as aforesaid, or intended, agreed or
covenanted so to be, together with all the tenements, hereditaments and appurtenances thereto appertaining (said properties, rights, privileges and franchises, including any cash and securities
hereafter deposited or required to be deposited with the Trustee (other than any such cash which is specifically stated in the Original Indenture not to be deemed part of the Trust Estate) being part
of the Trust Estate), unto the Trustee, and its successors and assigns in the trust created by the Indenture, forever. 


3







 



        SUBJECT, HOWEVER, to (i) Permitted Exceptions and (ii) to the extent permitted by Section 13.6 of the Original
Indenture as to property hereafter acquired (a) any duly recorded or perfected prior mortgage or other lien that may exist thereon at the date of the acquisition thereof by the Company and
(b) purchase money mortgages, other purchase money liens, chattel mortgages, conditional sales agreements or other title retention agreements created by the Company at the time of acquisition
thereof. 


        BUT IN TRUST, NEVERTHELESS, with power of sale, for the equal and proportionate benefit and security of the Holders from time to time of
all the Outstanding Secured Obligations without any priority of any such Obligation over any other such Obligation and for the enforcement of the payment of such Obligations in accordance with their
terms. 


        UPON CONDITION that, until the happening of an Event of Default and subject to the provisions of Article V of the Original
Indenture, and not in limitation of the rights elsewhere provided in the Indenture, including the rights set forth in Article V of the Original Indenture, the Company shall be permitted to
(i) possess and use the Trust Estate, except cash, securities, Designated Qualifying Securities and other personal property deposited, or required to be deposited, with the Trustee,
(ii) explore for, mine, extract, separate and dispose of coal, ore, gas, oil and other minerals, and harvest standing timber, and (iii) receive and use the rents, issues, profits,
revenues and other income, products and proceeds of the Trust Estate. 


        THE INDENTURE, INCLUDING THIS THIRTY-THIRD SUPPLEMENTAL INDENTURE, is given to secure the Outstanding Secured Obligations, and is intended
to operate and is to be construed as a deed passing title to the Trust Estate and is made under the provisions of the laws of the State of Georgia relating to deeds to secure debt, and not as a
mortgage or deed of trust, and is given to secure the Outstanding Secured Obligations. Should the indebtedness secured by the Indenture be paid according to the tenor and effect thereof when the same
shall become due and payable and should the Company perform all covenants contained in the Indenture in a timely manner, then the Indenture shall be canceled and surrendered. 


        AND IT IS HEREBY COVENANTED AND DECLARED that the Series 2006 (P-8) Notes are to be authenticated and delivered and the
Trust Estate is to be held and applied by the Trustee, subject to the covenants, conditions and trusts set forth herein and in the Original Indenture, and the Company does hereby covenant and agree to
