 (Reverse Side of Note) 
  
 This Note is one of a duly authorized issue of Securities of the Company issued and issuable in one or more series under an
Indenture, dated as of November 1, 1993 (such Indenture, together with any constituent instruments establishing the terms of particular Securities, being herein called the “Indenture”), of the Company to The Bank of New York (as successor
to NationsBank of Georgia, National Association), as trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made
for a more complete statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Notes and of the terms upon which the Notes are, and are to be, authenticated and
delivered. The acceptance of this Note shall be deemed to constitute the consent and agreement by the Holder hereof to all of the terms and provisions of the Indenture. This Note is one of the series designated on the face hereof as 5.70% Notes due
January 15, 2035 in the aggregate principal amount of $40,000,000. Capitalized terms used but not defined herein shall have the meanings set forth in the Indenture. 
  
 The Company shall have the right, subject to the terms and conditions of the Indenture, to redeem this Note, in whole or in
part, at any time and from time to time on or after January 15, 2010, at the option of the Company, without premium, at a Redemption Price equal to 100% of the principal amount being redeemed plus accrued but unpaid interest on the principal amount
being redeemed to the Redemption Date. 
  
 In the event that less
than all of the Notes are to be redeemed at any time, selection of such Notes for redemption will be made by The Depository Trust Company (the “Depositary”) during any period the Notes are issued in the form of a global security registered
in the name of the Depositary or a nominee thereof; provided that during any period the Notes are issued in certificated form, the selection of such Notes for redemption will be made by the Trustee by lot or by such other method as the
Trustee in its sole discretion shall deem fair and appropriate. In no event shall notes of a principal amount of $1,000 or less be redeemed in part. Notice of redemption shall be given by mail to Holders of the Notes to be redeemed, not less than 30
days nor more than 60 days prior to the date fixed for redemption, all as provided in the Indenture. If, at the time notice of redemption is given, the redemption moneys are not held by the Trustee, the redemption may be made subject to their
receipt on or before the date fixed for redemption and such notice shall be of no effect unless such moneys are so received. If the redemption notice is given and funds deposited as required by the Indenture, then interest will cease to accrue on
and after the Redemption Date on the Notes or portions of Notes called for redemption. If the Company does not deposit redemption moneys on or before the date fixed for redemption, the principal amount of the Notes called for redemption will
continue to bear interest as the rate of 5.70% per annum until paid. 
  
 In the event of redemption of this Note in part only, a new Note or Notes of this series, of like tenor, for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof. 
  
 Unless the Notes have been declared due and payable prior to the Started
Maturity Date by reason of an Event of Default, or the Notes have been previously redeemed or otherwise 

  

 6 

 
repaid, the Company shall be obligated to redeem all or part of this Note, in integral multiples of $1,000 principal amount, upon the request of the
representative of a deceased beneficial owner thereof (or a surviving joint tenant(s) by the entirety or the trustee of a trust to the extent hereinafter specified); provided, however, that during the period from the Original Issue Date through and
including January 15, 2006 (the “Initial Period”), and during any twelve-month period which ends on and includes each January 15 thereafter (each, a “Subsequent Period”), the Company will not be required to redeem (1) during any
such period, on behalf of any one deceased beneficial owner, any interest in Notes that exceeds $25,000 in principal amount, or (2) during any such period, ownership interests in the Notes exceeding $800,000 in aggregate principal amount for all
representatives so requesting redemption. A request for redemption may be presented to the participant through whom the deceased beneficial owner owned such interest in the Note at any time and in any principal amount. If the Company, although not
obligated to do so, chooses to redeem interests in the Notes of this series in excess of the $25,000 limitation, such redemption, to the extent it exceeds the $25,000 limitation with respect to any deceased beneficial owner, shall not be included in
the computation of the $800,000 aggregate limitation for such Initial Period or any Subsequent Period. If the Company, although not obligated to do so, chooses to redeem interests in the Notes of this series in excess of the $800,000 aggregate
limitation, any such redemption, to the extent it exceeds the $800,000 aggregate limitation, shall not reduce the aggregate limitation for any Subsequent Period. 
  
 A request for redemption of Notes may be made by delivering a request to the participant through whom the deceased
beneficial owner owned such interest in the Note, in form satisfactory to the participant, together with evidence of death and authority of the representative satisfactory to the participant, such waivers, notices or certificates as may be required
under applicable state or federal law, and such other evidence of the right to redemption as the participant shall require. The redemption request shall specify the principal amount and maturity or maturities of the Notes to be redeemed, provided
that this principal amount shall be in integral multiples of $1,000. The participant shall deliver the redemption request to the Depositary, who shall in turn forward the request to the Trustee. Subject to the $25,000 limitation and the $800,000
aggregate limitation, the Company will redeem the interest of such deceased beneficial owner in the Notes within sixty (60) days following receipt by the Company of the redemption request from the Trustee. If redemption requests exceed the $800,000
aggregate limitation during the Initial Period or any Subsequent Period, then such excess redemption requests will be applied in the order received by the Trustee to successive Subsequent Periods, regardless of the number of Subsequent Periods
required to redeem the Notes. 
  
 The Company may at any time
notify the Trustee that it will redeem, on a date not less than 30 days thereafter, all or any such principal amount of Notes for which redemption requests have been received but which are not then eligible for redemption by reason of the $25,000
individual limitation or the $800,000 aggregate limitation. Any Notes which are so redeemed shall be redeemed in the order of receipt of redemption requests by the Trustee. 
  
 The price to be paid by the Company for Notes to be redeemed pursuant to a redemption request will be one hundred percent
(100%) of the principal amount thereof plus accrued but unpaid interest to the date of payment. Payment for interests in the Notes that are to be redeemed shall be made to the Depositary upon presentation of Notes to the Trustee for redemption in
the aggregate principal amount specified in the redemption request submitted to 

  

 7 

 
the Trustee by the Depositary that are to be fulfilled in connection with such payment. The principal amount of any Notes acquired or redeemed by the Company
other than by redemption at the option of any representative of a deceased beneficial owner shall not be included in the computation of either the $25,000 limitation or the $800,000 aggregate limitation for the Initial Period or any Subsequent
Period. 
  
 An interest in a Note held in tenancy by the entirety,
joint tenancy or by tenants in common will be deemed to be held by a single beneficial owner and the death of a tenant by the entirety, joint tenant or tenant in common will be deemed the death of a beneficial owner. The death of a person who,
during his lifetime, was entitled to substantially all of the rights of a beneficial owner of an interest in the notes will be deemed the death of the beneficial owner, regardless of the recordation of such interest on the records of the
participant, if such rights can be established to the satisfaction of the participant. Such interests shall be deemed to exist in typical cases of nominee ownership, ownership under the Uniform Gifts to Minors Act or the Uniform Transfers to Minors
Act, community property or other similar joint ownership arrangements, including individual retirement accounts or Keogh [H.R. 10] plans maintained solely by or for the decedent or by or for the decedent and any spouse, and trust and certain other
arrangements where one person has substantially all of the rights of a beneficial owner during such person’s lifetime. 
  
 In the case of a redemption request which is presented on behalf of a deceased beneficial owner and which has not been fulfilled at the time the Company
gives notice to the Trustee of its election to redeem the Notes, the Notes which are the subject of the pending redemption request shall be redeemed prior to any other Notes. 
  
 Any redemption request may be withdrawn by the person(s) presenting the same upon delivery of a written request for such
withdrawal given by the participant on behalf of such person(s) to the Depositary and by the Depositary to the Trustee not less than 60 days prior to payment thereof by the Company. 
  
 The Company may, at its option, purchase any Notes for which redemption requests have been received in lieu of redeeming
such Notes. Any Notes so purchased by the Company shall either be reoffered for sale and sold within 180 days after the date of purchase or presented to the Trustee for redemption and cancellation. Any such acquisition of Notes by the Company will
not be included in the computation of the $25,000 individual limitation or the $800,000 aggregate limitation for the Initial Period or any Subsequent Period. 
  
 During such time or times as this Note is not represented by a global security and is issued in definitive form, all references in this Note to
participants and the Depositary, including the Depositary’s governing rules, regulations and procedures, shall be deemed deleted, all determinations which under this Note the participants are required to make shall be made by the Company
(including, without limitation, determining whether the applicable decedent is in fact the beneficial owner of the interest in this Note or is in fact deceased and whether the representative is duly authorized to request redemption on behalf of the
applicable beneficial owner), all redemption requests, to be effective, shall be delivered by the representative to the trustee, with a copy to the Company, and shall be in the form of a redemption request (with appropriate changes to reflect the
fact that such redemption request is being executed by a 

  

 8 

 
representative) and, in addition to all documents that are otherwise required to accompany a redemption request, shall be accompanied by this Note.

  
 If an Event of Default with respect to the Notes of this
series shall occur and be continuing, the principal of and interest on the Notes of this series may be declared due and payable in the manner, with the effect and subject to the conditions provided in the Indenture. 
  
 The Indenture permits, with certain exceptions as therein provided, the
Trustee to enter into one or more supplemental indentures for the purpose of adding any provisions to, or changing in any manner or eliminating any of the provisions of, the Indenture with the consent of the Holders of not less than a majority in
aggregate principal amount of the Securities of all series then Outstanding under the Indenture, considered as one class; provided, however, that if there shall be Securities of more than one series Outstanding under the Indenture and if a proposed
supplemental indenture shall directly affect the rights of the Holders of Securities of one or more, but less than all, of such series, then the consent only of the Holders of a majority in aggregate principal amount of the Outstanding Securities of
all series so directly affected, considered as one class, shall be required; and provided, further, that if the Securities of any series shall have been issued in more than one Tranche and if the proposed supplemental indenture shall directly affect
the rights of the Holders of Securities of one or more, but less than all, of such Tranches, then the consent only of the Holders of a majority in aggregate principal amount of the Outstanding Securities of all Tranches so directly affected,
considered as one class, shall be required. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities then Outstanding, on behalf of the Holders of all Securities, 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 Note shall be conclusive and binding upon such Holder and upon
all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange therefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note. 
  
 No reference herein to the Indenture and no provision of this Note or of the
Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest on this Note at the times, places and rates, in the coin or currency, and in the manner, prescribed herein and
in the Indenture. 
  
 As provided in the Indenture and subject to
certain limitations therein set forth, the transfer or exchange of this Note is registrable in the Security Register, upon surrender of this Note for registration of transfer or exchange at the offices of The Bank of New York, Jacksonville, Florida
or such other office or agency as may be designated by the Company from time to time, 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 Notes of like tenor and aggregate principal amount, will be issued to the designated transferee or transferees or to the Holder, as the case may be. 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. 
  

 9 

 As provided in the Indenture and subject to certain limitations therein set forth, Notes of this series
are exchangeable for a like tenor and aggregate principal amount of Notes of this series, of any authorized denominations, as requested by the Holder surrendering the same, upon surrender of the Note or Notes to be exchanged at the office or agency
designated by the Company from time to time. The Company shall not be required to (a) issue, register the transfer of or exchange Notes of this series during a period of 15 days immediately preceding the date notice is given identifying the serial
numbers of the Notes of this series called for redemption or (b) issue, register the transfer of or exchange any Note so selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part. 
  
 The Notes of this series are issuable only in registered form, without
coupons, in denominations of $1,000, and any amount in excess thereof that is an integral multiple of $1,000. 
  
 Prior to due presentment of this Note 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 Note is registered as the absolute owner hereof for all purposes, whether or not this Note be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary. 
  
 The Indenture and the Notes shall be governed by and construed in accordance
with the laws of the State of New York.

 (Reverse Side of Note) 
  
 This Note is one of a duly authorized issue of Securities of the Company issued and issuable in one or more series under an
Indenture, dated as of November 1, 1993 (such Indenture, together with any constituent instruments establishing the terms of particular Securities, being herein called the “Indenture”), of the Company to The Bank of New York (as successor
to NationsBank of Georgia, National Association), as trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made
for a more complete statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Notes and of the terms upon which the Notes are, and are to be, authenticated and
delivered. The acceptance of this Note shall be deemed to constitute the consent and agreement by the Holder hereof to all of the terms and provisions of the Indenture. This Note is one of the series designated on the face hereof as 5.20% Notes due
January 15, 2020 in the aggregate principal amount of $40,000,000. Capitalized terms used but not defined herein shall have the meanings set forth in the Indenture. 
  
 The Company shall have the right, subject to the terms and conditions of the Indenture, to redeem this Note, in whole at any
time or in part from time to time, at the option of the Company, at a Redemption Price equal to the greater of (1) 100% of the principal amount being redeemed or (2) the sum of the present values of the remaining scheduled payments of principal and
interest on the Notes being redeemed, discounted to the Redemption Date on a semiannual basis, assuming a 360-day year consisting of twelve 30-day months, at the “Treasury Yield,” as defined below, plus 0.20%, plus in each case accrued
interest to the Redemption Date. 
  
 As used in the Notes, the
following terms shall have the following respective meanings. 
  
 “Treasury Yield” means, with respect to any Redemption Date, the rate per year equal to the semiannual equivalent yield to maturity of the “Comparable Treasury Issue,” as defined below, assuming a price for the
Comparable Treasury Issue, expressed as a percentage of its principal amount equal to the “Comparable Treasury Price,” as defined below, for the Redemption Date. 
  
 “Comparable Treasury Issue” means the United States Treasury security selected by an “Independent Investment
Banker,” as defined below, as having a maturity comparable to the remaining term of the Notes that the Independent Investment Banker would utilize, at the time of selection and in accordance with customary financial practice, in pricing new
issues of corporate debt securities of comparable maturity to the remaining term of the Notes. 
  
 “Independent Investment Banker” means one of the “Reference Treasury Dealers” as defined below, appointed by the Trustee after consultation with the Company. 
  
 “Comparable Treasury Price” means, with respect to any Redemption
Date, (1) the average of the bid and asked prices for the Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, on the third Business Day preceding the Redemption Date, as set forth in the daily statistical
release, or any successor release, published by the Federal Reserve Bank of New York and designated “Composite 3:30 p.m. Quotations for U.S. 

  

 6 

 
Government Securities” or (2) if that release or any successor release is not published or does not contain those prices on that Business Day, (A) the
average of the “Reference Treasury Dealer Quotations,” as defined below, for the Redemption Date, after excluding the highest and lowest Reference Treasury Dealer Quotations for the Redemption Date, or (B) if the Trustee obtains fewer than
four Reference Treasury Dealer Quotations, the average of all the quotations which the Trustee obtains. 
  
 “Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any Redemption Date, the average, as determined
by the Company, of the bid and asked prices for the Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, quoted in writing to the Company by the Reference Treasury Dealer at 5:00 p.m. on the third Business Day
preceding the Redemption Date. 
  
 “Reference Treasury
Dealer” means any primary U.S. Government securities dealer in New York City selected by the Company. 
  
 In the event that less than all of the Notes are to be redeemed at any time, selection of such Notes for redemption will be made by The Depository Trust
Company (“DTC”) during any period the Notes are issued in the form of a global security registered in the name of DTC or a nominee thereof; provided that during any period the Notes are issued in certificated form, the selection of
such Notes for redemption will be made by the Trustee by lot or by such other method as the Trustee in its sole discretion shall deem fair and appropriate. In no event shall notes of a principal amount of $1,000 or less be redeemed in part. Notice
of redemption shall be given by mail to Holders of the Notes to be redeemed, not less than 30 days nor more than 60 days prior to the date fixed for redemption, all as provided in the Indenture. If, at the time notice of redemption is given, the
redemption moneys are not held by the Trustee, the redemption may be made subject to their receipt on or before the date fixed for redemption and such notice shall be of no effect unless such moneys are so received. If the redemption notice is given
and funds deposited as required by the Indenture, then interest will cease to accrue on and after the Redemption Date on the Notes or portions of Notes called for redemption. If the Company does not deposit redemption moneys on or before the date
fixed for redemption, the principal amount of the Notes called for redemption will continue to bear interest as the rate of 5.20% per annum until paid. 
  
 In the event of redemption of this Note in part only, a new Note or Notes of this series, of like tenor, for the unredeemed portion hereof will be issued
in the name of the Holder hereof upon the cancellation hereof. 
  
 If an Event of Default with respect to the Notes of this series shall occur and be continuing, the principal of and interest on the Notes of this series may be declared due and payable in the manner, with the effect and subject to the
conditions provided in the Indenture. 
  
 The Indenture permits,
with certain exceptions as therein provided, the Trustee to enter into one or more supplemental indentures for the purpose of adding any provisions to, or changing in any manner or eliminating any of the provisions of, the Indenture with the consent
of the Holders of not less than a majority in aggregate principal amount of the Securities of all series then Outstanding under the Indenture, considered as one class; provided, however, that if 

  

 7 

 
there shall be Securities of more than one series Outstanding under the Indenture and if a proposed supplemental indenture shall directly affect the rights
of the Holders of Securities of one or more, but less than all, of such series, then the consent only of the Holders of a majority in aggregate principal amount of the Outstanding Securities of all series so directly affected, considered as one
class, shall be required; and provided, further, that if the Securities of any series shall have been issued in more than one Tranche and if the proposed supplemental indenture shall directly affect the rights of the Holders of Securities of one or
more, but less than all, of such Tranches, then the consent only of the Holders of a majority in aggregate principal amount of the Outstanding Securities of all Tranches so directly affected, considered as one class, shall be required. The Indenture
also contains provisions permitting the Holders of specified percentages in principal amount of the Securities then Outstanding, on behalf of the Holders of all Securities, 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 Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued upon the
registration of transfer hereof or in exchange therefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note. 
  
 No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of and interest on this Note at the times, places and rates, in the coin or currency, and in the manner, prescribed herein and in the Indenture. 
  
 As provided in the Indenture and subject to certain limitations therein set
forth, the transfer or exchange of this Note is registrable in the Security Register, upon surrender of this Note for registration of transfer or exchange at the offices of The Bank of New York, Jacksonville, Florida or such other office or agency

authorized in writing, and thereupon one or more new Notes of like tenor and aggregate principal amount, will be issued to the designated transferee or transferees or to the Holder, as the case may be. 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. 
  
 As provided in the Indenture and subject to certain limitations therein set forth, Notes of this series are exchangeable for
a like tenor and aggregate principal amount of Notes of this series, of any authorized denominations, as requested by the Holder surrendering the same, upon surrender of the Note or Notes to be exchanged at the office or agency designated by the
Company from time to time. The Company shall not be required to (a) issue, register the transfer of or exchange Notes of this series during a period of 15 days immediately preceding the date notice is given identifying the serial numbers of the
