(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 30 basis points, plus accrued and unpaid interest on the principal amount being redeemed to but excluding the Redemption Date.

(c) On or after September 15, 2022, 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 to but excluding the Redemption Date.

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 less than five Business Days (as defined below) 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 15 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.

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 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.

EQUIFAX INC.

3.30% Senior Notes due 2022

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 June 29, 1998 (hereinafter called the “Original Indenture”), duly executed and delivered by the Issuer to The Bank of New York Mellon Trust Company, N.A. (formerly known as The Bank of New York Trust Company, N.A. as successor to Bank One Trust Company, N.A., which was successor in interest to The First National Bank of Chicago), 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 December 17, 2012, 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. 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 3.30% Senior Notes due 2022 of the Issuer, initially limited in aggregate principal amount to $500,000,000.

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 September 15, 2022, the Issuer shall have the right to redeem to 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 an 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 30 basis points, plus accrued and unpaid interest on the principal amount being redeemed to, but excluding, the Redemption Date.

On or after September 15, 2022, 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, including additional interest, if any, 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 30 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 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 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.

A-5

Upon the occurrence of a Special Mandatory Redemption Triggering Event, the Issuer shall redeem the Notes in full on the Special Mandatory Redemption Date at a redemption price equal to 101% of the principal amount of the Notes plus accrued and unpaid interest from the date of the initial issuance of the Notes, or the most recent Interest Payment Date, whichever is later, to but excluding the Special Mandatory Redemption Date.

The Issuer, or the Trustee on the Issuer’s behalf, will cause notice of the Special Mandatory Redemption to be mailed promptly after the occurrence of the Special Mandatory Redemption Triggering Event to each Holder at its registered address. If funds sufficient to fund the Special Mandatory Redemption of all Notes to be redeemed on the Special Mandatory Redemption Date are deposited with the paying agent on or before the Special Mandatory Redemption Date and the other conditions set forth in Section 1.7 of the Fourth Supplemental Indenture have been satisfied, all of the Notes will be redeemed on the Special Mandatory Redemption Date and on and after such date the Notes will cease to bear interest and all rights under such Notes will terminate.

If a Change of Control Triggering Event occurs, unless the Issuer has exercised its option to redeem the Securities of this series, the Issuer shall be required to make an offer (the “Change of Control Offer”) to each Holder of the Notes of this series 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 of this series repurchased, plus accrued and unpaid interest, if any, on the Notes of this series 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, a notice shall be mailed to Holders of the Notes of this series 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 30 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 “Election Form” (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, 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;

A-6

(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

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 of this series or portions of such Notes properly tendered pursuant to the Change of Control Offer, (2) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes of this series or portions of such Notes properly tendered, and (3) deliver or cause to be delivered to the Trustee the Notes of this series properly accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes of this series or portions of such Securities 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 addition, the Issuer shall not repurchase any Securities of this series if there has occurred and is continuing on the Change of Control Payment Date an Event of Default under the Original Indenture, other than a default in the payment of the Change of Control Payment upon a Change of Control Triggering Event.

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 Securities of this series 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 of this series, 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 Securities of this series by virtue of any such conflict.
