following any Change of Control Triggering Event or, at the Issuer’s option, prior to any Change of Control, but after public announcement of the transaction that constitutes or may constitute the Change of Control, the Issuer shall mail a
notice to Holders of the Notes describing the transaction that constitutes or may constitute the Change of Control Triggering Event and offering to repurchase such Notes on the date specified in the notice, which date shall be no earlier than 15
days and no later than 60 days from the date such notice is mailed (the “Change of Control Payment Date”). The notice shall, if mailed prior to the date of consummation of the Change of Control, state that the offer to purchase is
conditioned on the Change of Control Triggering Event occurring on or prior to the Change of Control Payment Date. 

(c)    In order to accept the Change of Control Offer, the Holder must deliver to the Paying Agent, at least three
Business Days prior to the Change of Control Payment Date, the Note together with the form entitled “Option of Holder to Elect Purchase” (which form is annexed to the Note) duly completed, or a telegram, telex, facsimile transmission or a

Purchase” duly completed, will be received by the Paying Agent at least three Business Days prior to the Change of Control Payment Date. 

(d)    Any exercise by a Holder of its election to accept the Change of Control Offer shall be irrevocable. The Change of
Control Offer may be accepted for less than the entire principal amount of the Notes, but in that event the principal amount of the Notes remaining outstanding after repurchase must be equal to $2,000 or an integral multiple of $1,000 in excess
thereof.

Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Issuer and the third party purchases all Notes properly tendered and not withdrawn under its
offer. In addition, the Issuer shall not repurchase any Notes if there has occurred and is continuing on the Change of Control Payment Date an Event of Default under the Indenture with respect to the Notes, other than a default in the payment of the
Change of Control Payment upon a Change of Control Triggering Event. 
 (g)    The Issuer shall comply with the
requirements of Rule 14e-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and any other securities laws and regulations thereunder to the extent those laws
and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any such securities laws or regulations conflict with the Change of Control Offer
provisions of the Notes, the Issuer shall comply with those securities laws and regulations and shall not be deemed to have breached its obligations under the Change of Control Offer provisions of the Notes by virtue of any such conflict.

that, in the case of subclauses (A) through (D) of this clause (i), the lien of any such mortgage, pledge or other lien does not spread to property owned prior to such acquisition or
construction or to other property thereafter acquired or constructed other than additions to such acquired or constructed property and other than property on which property so constructed is located; and provided, further, that if a
firm commitment from a bank, insurance company or other lender or investor (not including the Issuer, a Subsidiary or an Affiliate of the Issuer) for the financing of the acquisition or construction of property is made prior to, contemporaneously
with or within the 360-day period hereinabove referred to, the applicable mortgage, pledge, lien or encumbrance shall be deemed to be permitted by this clause (i) whether or not
created or assumed within such period; 

  
 11 








 (ii)    any mortgage, pledge or other lien or encumbrance
created for the sole purpose of extending, renewing or refunding any mortgage, pledge, lien or encumbrance permitted by clause (i) of this subsection (a); provided, however, that the
principal amount of indebtedness secured thereby shall not exceed the principal amount of indebtedness so secured at the time of such extension, renewal or refunding and that such extension, renewal or refunding mortgage, pledge, lien or encumbrance
shall be limited to all or any part of the same property that secured the mortgage, pledge or other lien or encumbrance extended, renewed or refunded; 

(iii)    liens for taxes or assessments or governmental charges or levies not then due and delinquent or
the validity of which is being contested in good faith, and against which an adequate reserve has been established; liens on any such property created in connection with pledges or deposits to secure public or statutory obligations or to secure

other restrictions on the use of real property or minor irregularities in the title thereto; and any other liens and encumbrances similar to those described in this clause (iii), the existence of which does not, in the
opinion of the Issuer, materially impair the use by the Issuer or a Subsidiary of the affected property in the operation of the business of the Issuer or a Subsidiary, or the value of such property for the purposes of such business; 

(iv)    any contracts for production, research or development with or for the Government, directly or
indirectly, providing for advance, partial or progress payments on such contracts and for a lien, paramount to all other liens, upon money advanced or paid pursuant to such contracts, or upon any material or supplies in connection with the
performance of such contracts to secure such payments to the Government; and liens or other evidences of interest in favor of the Government, paramount to all other liens, on any equipment, tools, machinery, land or buildings hereafter constructed,
installed or purchased by the Issuer or a Subsidiary primarily for the purpose of manufacturing or producing any product or performing any development work, directly or indirectly, for the Government to secure indebtedness incurred and owing to the
Government for the construction, installation or purchase of such equipment, tools, machinery, land or buildings. For the purpose of this clause (iv), “Government” shall mean the Government of the United
States of America and any department, agency or political subdivision thereof and the government of any foreign country with which the Issuer or its Subsidiaries is permitted to do business under applicable law and any department, agency or
political subdivision thereof; 
 (v)    any mortgage, pledge or other lien or encumbrance created after
the date of this Fourth Supplemental Indenture on any property leased to or purchased by the Issuer or a Subsidiary after that date and securing, directly or indirectly, obligations issued by a state, a territory or a possession of the United
States, or any political subdivision of any of the foregoing, or the District of Columbia, to finance the cost of acquisition or cost of construction of such property, provided that the interest paid on such obligations is entitled to be excluded
from gross income of the recipient pursuant to Section 103(a) of the Internal Revenue Code of 1986, as amended (or any successor to such provision), as in effect at the time of the issuance of such obligations; 

  
 12 








 (vi)    any mortgage, pledge or other lien or encumbrance on
any property now owned or hereafter acquired or constructed by the Issuer or a Subsidiary, or on which property so owned, acquired or constructed is located, to secure or provide for the payment of any part of the construction price or cost of
improvements of such property, and created prior to, contemporaneously with or within 360 days after, such construction or improvement; provided, that if a firm commitment from a bank, insurance company or other lender or investor (not including the
Issuer, a Subsidiary or an Affiliate of the Issuer) for the financing of the acquisition or construction of property is made prior to, contemporaneously with or within the 360-day period hereinabove referred
to, the applicable mortgage, pledge, lien or encumbrance shall be deemed to be permitted by this clause (vi) whether or not created or assumed within such period; and 

(vii)    any mortgage, pledge or other lien or encumbrance not otherwise permitted under this
Section 7.1(a); provided, the aggregate amount of indebtedness secured by all such mortgages, pledges, liens or encumbrances, together with the aggregate sale price of property involved in sale and leaseback
transactions not otherwise permitted except under Section 7.1(b)(i) does not exceed 15% of Consolidated Stockholders’ Equity. 

(b)    Limitation on Sale and Leaseback Transactions. The Issuer will not, and will not permit any Subsidiary to,
sell or transfer (except to the Issuer or one or more Wholly-Owned Subsidiaries, or both) any Principal Facility owned by it on the date of this Fourth Supplemental Indenture with the intention of taking back a lease of such property, other than a
lease for a temporary period (not exceeding 36 months) with the intent that the use by the Issuer or such Subsidiary of such property will be discontinued at or before the expiration of such period, unless either: 

(i)    the sum of the aggregate sale price of property involved in sale and leaseback transactions not
otherwise permitted pursuant to this Section 7.1(b) plus the aggregate amount of indebtedness secured by all mortgages, pledges, liens and encumbrances not otherwise permitted except under
Section 7.1(a)(vii) does not exceed 15% of Consolidated Stockholders’ Equity; or 

(ii)    the Issuer within 120 days after the sale or transfer shall have been made by the Issuer or by any
such Subsidiary applies an amount equal to the greater of (A) the net proceeds of the sale of the Principal Facility sold and leased back pursuant to such arrangement or (B) the fair market value of the Principal Facility sold and leased
back at the time of entering into such arrangement (which may be conclusively determined by the Board of Directors of the Issuer) to the retirement of Securities or other Funded Debt of the Issuer ranking on a parity with the Securities; provided,
that the amount required to be applied to the retirement of Outstanding Securities or other Funded Debt of the Issuer pursuant to this subclause (B) shall be reduced by (1) the principal amount (or, if the Securities
of that series are Discount Securities, such portion of the principal amount as may be specified in the terms of that series) of any Securities delivered within 120 days after such sale to the Trustee for retirement and cancellation, and
(2) the principal amount of any other Funded Debt of the Issuer ranking on a parity with the Securities voluntarily retired by the Issuer within 120 days after such sale. Notwithstanding the foregoing, no retirement referred to in this
clause (ii) may be effected by payment at maturity or pursuant to any mandatory sinking fund payment or any mandatory prepayment provision.

pursuant to Section 301(15) of the Original Indenture, Section 703 of the Original Indenture is hereby amended by deleting such Section in its entirety and substituting in lieu thereof the following: 

(i)    For so long as any Notes are Outstanding, if the Issuer is subject to Section 13(a) or 15(d) of
the Exchange Act or any successor provision, the Issuer will deliver to the Trustee the annual reports, quarterly reports and other documents which the Issuer is required to file with the Commission pursuant to Section 13(a) or 15(d) or any
successor provision, within 15 days after the date that the Issuer files the same with the Commission. If the Issuer is not subject to Section 13(a) or 15(d) of the Exchange Act or any successor provision, and for so long as any Notes
are Outstanding, the Issuer will deliver to the Trustee the quarterly and annual financial statements and accompanying Item 303 of Regulation S-K (“management’s discussion and analysis of financial
condition and results of operations”) disclosure that would be required to be contained in annual reports on Form 10-K and quarterly reports on Form 10-Q required

SEC rules and regulations. 
 (ii)    Reports and other documents filed by the Issuer with the Commission
and publicly available via the EDGAR system or on the Issuer’s website will be deemed to be delivered to the Trustee as of the time such filing is publicly available via EDGAR or on the Issuer’s website for purposes of this covenant;
provided, however, that the Trustee shall have no obligation whatsoever to determine whether or not such information, documents or reports have been filed or are publicly available via EDGAR or on the Issuer’s website. Delivery of such
reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained
therein, including the Issuer’s compliance with any of its covenants relating to the Notes (as to which the Trustee is entitled to rely exclusively on an Officers’ Certificate).

obligor to a date more than one year, after the date of determination thereof (excluding any amount thereof included in current liabilities).

 EQUIFAX INC. 

3.950% Senior Notes due 2023 

Equifax Inc., a Georgia corporation (the “Issuer,” which term includes any successor under the Original Indenture
hereinafter referred to), for value received, hereby promises to pay to Cede & Co. or its registered assigns, the principal sum of [__] Dollars on June 15, 2023 (the “Maturity Date”), and to pay interest thereon from
May 25, 2018 (or from the most recent interest payment date to which interest has been paid or duly provided for) in U.S. dollars semi-annually in arrears on June 15 and December 15 of each year, each, an “Interest Payment
Date”, commencing on December 15, 2018, and on the Maturity Date, at the rate of 3.950% per annum, until payment of said principal sum has been made or duly provided for. 

The interest so payable and punctually paid or duly provided for on any Interest Payment Date and on the Maturity Date will be paid to the
Holder in whose name this Note (or one or more predecessor Notes) is registered at the close of business on the “Record Date” for such payment, which will be June 1 and December 1 (regardless of whether such day is a Business Day
(as defined below)). Any interest not so punctually paid or duly provided for shall forthwith cease to be payable to the Holder on such record date, and shall be paid to the Holder in whose name this Note (or one or more predecessor Notes) is
registered at the close of business on a subsequent record date for the payment of such defaulted interest (which shall be not more than 15 days and not less than 10 days prior to the date of the payment of such defaulted interest) established by
notice given by mail by or on behalf of the Issuer to the Holders of the Notes not less than 10 days preceding such subsequent record date. Interest on this Note will be computed on the basis of a 360-day year
of twelve 30-day months. 
 The principal of this Note payable on the Maturity Date will be paid
against presentation and surrender of this Note at the office or agency of the Issuer maintained for that purpose in The Borough of Manhattan, The City of New York. The Issuer hereby initially designates U.S. Bank Global Corporate Trust Services
– New York, 100 Wall Street, Suite 1600, New York, NY 10005 as the office to be maintained by it where Notes may be presented for payment, registration of transfer, or exchange and where notices or demands to or upon the Issuer in respect of
the Notes or the Original Indenture referred to on the reverse hereof may be served. 
 Interest payable on this Note on any Interest
Payment Date and on the Maturity Date, as the case may be, will be the amount of interest accrued from and including the immediately preceding Interest Payment Date (or from and including May 25, 2018, in the case of the initial Interest
Payment Date) to but excluding the applicable Interest Payment Date or the Maturity Date, as the case may be. If any Interest Payment Date or the Maturity Date falls on a day that is not a Business Day (as defined below), the required payment of
interest or principal or both, as the case may be, will be made on the next succeeding Business Day with the same force and effect as if it were made on the date such payment was due and no interest will accrue on the amount so payable for the
period from and after such Interest Payment Date or the Maturity Date, as the case may be. “Business Day” means any calendar day, that is not a Saturday, Sunday or legal holiday in New York, New York and on which commercial banks are open
for business in New York, New York. 

  
 A-2 








 Payments of principal and interest in respect of this Note will be made by wire transfer of
immediately available funds in such coin or currency of the United States of America as at the time of payment is legal tender for the payment of public and private debts. 

Reference is made to the further provisions of this Note set forth on the reverse hereof. Such further provisions shall for all purposes have
the same effect as though fully set forth at this place. 
 This Note shall not be entitled to the benefits of the Original Indenture
referred to on the reverse hereof or be valid or become obligatory for any purpose until the certificate of authentication hereon shall have been signed by the Trustee under such Indenture.

 [REVERSE OF NOTE] 

EQUIFAX INC. 
 3.950%
Senior Notes due 2023 
 This security is one of a duly authorized issue of debentures, notes, bonds, or other evidences of indebtedness
of the Issuer (hereinafter called the “Securities”) of the series hereinafter specified, all issued or to be issued under and pursuant to an Indenture dated as of May 12, 2016 (hereinafter called the “Original
Indenture”), duly executed and delivered by the Issuer to U.S. Bank National Association, as Trustee (hereinafter called the “Trustee,” which term includes any successor trustee under the Original Indenture with
respect to the series of Securities of which this Note is a part), and a Fourth Supplemental Indenture, dated as of May 25, 2018, between the Issuer and the Trustee (the “Fourth Supplemental Indenture;” the Original Indenture
as modified and supplemented by the Fourth Supplemental Indenture is herein called the “Indenture”) to which the Original Indenture and all indentures supplemental thereto relating to this security reference is hereby made for a
description of the rights, limitations of rights, obligations, duties, and immunities thereunder of the Trustee, the Issuer, and the Holders of the Securities, and of the terms upon which the Securities are, and are to be, authenticated and
delivered. Capitalized terms used herein without definition shall have the meanings set forth in the Original Indenture. The Securities may be issued in one or more series, which different series may be issued in various aggregate principal amounts,
may mature at different times, may bear interest (if any) at different rates, may be subject to different redemption provisions (if any), and may otherwise vary as provided in the Original Indenture or any indenture supplemental thereto. This
security is one of a series designated as the 3.950% Senior Notes due 2023 of the Issuer (the “Notes”), initially limited in aggregate principal amount to $400,000,000. 

In case an Event of Default with respect to this security shall have occurred and be continuing, the principal hereof together with accrued
interest to the date of declaration, if any, may be declared, and upon such declaration shall become, due and payable, in the manner, with the effect, and subject to the conditions provided in the Original Indenture. 

Except as otherwise may be specified herein or in the Fourth Supplemental Indenture, prior to May 15, 2023, the Issuer shall have the
right to redeem the Notes, in whole or in part, at any time or from time to time, at a redemption price (the “Optional Redemption Price”) equal to the greater of (i) 100% of the principal amount plus accrued and unpaid interest to,
but excluding, the Redemption Date, and (ii) the sum of the present values of the Remaining Scheduled Payments of principal and interest (exclusive of interest accrued to the Redemption Date) discounted to the Redemption Date on a semi-annual
basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 25 basis points, plus accrued and unpaid interest on the
principal amount being redeemed to, but excluding, the Redemption Date. 
 On or after May 15, 2023, the Issuer shall have the right to
redeem the Notes, in whole or in part, at any time or from time to time, at the Issuer’s option, for an amount in cash equal to 100% of the principal amount plus any accrued and unpaid interest on the principal amount being redeemed to,
but excluding the Redemption Date. 
 The Issuer will mail notice of such redemption to the registered holders of the Notes to be redeemed
not less than 15 nor more than 60 days prior to the Redemption Date. If Notes are only partially redeemed pursuant to the Fourth Supplemental Indenture, the Notes to be redeemed will be selected by the Trustee in such manner as in its sole
discretion it shall deem appropriate and fair; provided, that if at 

  
 A-6 








 
the time of redemption the Notes to be redeemed are registered as a Global Note, the Depository shall determine, in accordance with its procedures, the principal amount of the Notes to be
redeemed held by each of its participants that holds a position in such Notes. The Optional Redemption Price shall be paid prior to 12:00 noon, New York time, on the Redemption Date or at such later time on such date as is then permitted by the
rules of the Depository for the Notes (if then registered as a Global Note); provided, that the Issuer shall deposit with the Trustee an amount sufficient to pay the Optional Redemption Price by 10:00 a.m., New York time, on the date such
Optional Redemption Price is to be paid. 
 If a Change of Control Triggering Event occurs, unless the Issuer has exercised its option to
redeem the Notes, the Issuer shall be required to make an offer (the “Change of Control Offer”) to each Holder of the Notes to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of that
Holder’s Notes on the terms set forth herein. In the Change of Control Offer, the Issuer shall be required to offer payment in cash equal to 101% of the aggregate principal amount of Notes repurchased, plus accrued and unpaid interest,
if any, on the Notes repurchased to the date of repurchase (the “Change of Control Payment”). Within 30 days following any Change of Control Triggering Event or, at the Issuer’s option, prior to any Change of Control, but after
public announcement of the transaction that constitutes or may constitute the Change of Control, the Issuer shall mail a notice to Holders of the Notes describing the transaction that constitutes or may constitute the Change of Control Triggering
Event and offering to repurchase such Securities on the date specified in the notice, which date shall be no earlier than 15 days and no later than 60 days from the date such notice is mailed (the “Change of Control Payment Date”). The
notice shall, if mailed prior to the date of consummation of the Change of Control, state that the offer to purchase is conditioned on the Change of Control Triggering Event occurring on or prior to the Change of Control Payment Date. 

In order to accept the Change of Control Offer, the Holder must deliver to the Paying Agent, at least three Business Days prior to the Change
of Control Payment Date, this Security together with the form entitled “Option of Holder to Elect Purchase” (which form is annexed hereto) duly completed, or a telegram, telex, facsimile transmission or a letter from a member of a national
securities exchange, or the Financial Industry Regulatory Authority, Inc., or a commercial bank or trust company in the United States setting forth: 

(i)    the name of the Holder of the Note; 

(ii)    the principal amount of the Note; 

(iii)    the principal amount of the Note to be repurchased; 

(iv)    the certificate number or a description of the tenor and terms of the Note; 

(v)    a statement that the Holder is accepting the Change of Control Offer; and 

(vi)    a guarantee that the Note, together with the form entitled “Option of Holder to Elect
Purchase” duly completed, will be received by the Paying Agent at least three Business Days prior to the Change of Control Payment Date. 

Any exercise by a Holder of its election to accept the Change of Control Offer shall be irrevocable. The Change of Control Offer may be
accepted for less than the entire principal amount of the Notes, but in that event the principal amount of the Notes remaining outstanding after repurchase must be equal to $2,000 or an integral multiple of $1,000 in excess thereof. On the Change of
Control Payment Date, the Issuer shall, to the extent lawful (1) accept for payment all Notes or portions of such Notes properly tendered pursuant to the Change of Control Offer, (2) deposit with the Paying Agent an amount


  
 A-7 








 
equal to the Change of Control Payment in respect of all Notes or portions of such Notes properly tendered, and (3) deliver or cause to be delivered to the Trustee the Notes properly
accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions of such Notes being repurchased. 

The Issuer shall not be required to make a Change of Control Offer upon the occurrence of a Change of Control Triggering Event if a third
party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Issuer and the third party purchases all Notes of this series properly tendered and not withdrawn under its offer. In

Control Payment upon a Change of Control Triggering Event.

connection with the repurchase of the Notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any such securities laws or regulations conflict with the Change of Control Offer provisions of the Notes, the
Issuer shall comply with those securities laws and regulations and shall not be deemed to have breached its obligations under the Change of Control Offer provisions of the Notes by virtue of any such conflict.
