This Security is one of the series designated on the face hereof, initially limited in aggregate principal amount to $                    .

Optional Redemption. The Securities of this series are subject to redemption at the Company’s option, at any time and from time to time, in whole or in part, at a Redemption Price equal to the greater of (i) 100% of the principal amount to be redeemed plus accrued and unpaid interest thereon to the Redemption Date, and (ii) the sum of the present values of the remaining scheduled payments of principal and interest on the Securities to be redeemed (exclusive of interest accrued to the Redemption Date) discounted to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30 day months) at the applicable Treasury Rate (as defined below) plus 50 basis points plus accrued and unpaid interest on the principal amount being redeemed to the Redemption Date.

For purposes of determining the optional redemption price, the following definitions are applicable:

“Treasury Rate” means, with respect to any Redemption Date for the Securities, the rate per annum equal to the semi-annual equivalent yield to maturity or interpolated (on a day count basis) of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date.

The Treasury Rate will be calculated on the third business day preceding the Redemption Date.

“Comparable Treasury Issue” means the U.S. Treasury security or securities selected by an Independent Investment Banker as having an actual or interpolated maturity comparable to the remaining term of the Securities that would be utilized, 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 terms of the Securities.

(a) the average of the Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or

Notice of any redemption will be mailed at least 30 days but not more than 60 days before the redemption date to each registered holder of Securities to be redeemed. Unless the Company defaults in payment of the redemption price, on and after the redemption date, interest will cease to accrue on the Securities or portions of the Securities called for redemption. If fewer than all of the Securities are to be redeemed, the Trustee will select, not more than 60 days prior to the redemption date, the particular Securities or portions thereof for redemption from the outstanding Securities not previously called by such method as the Trustee deems fair and appropriate.

Defaults and Remedies. If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.

A-5

majority in aggregate principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, 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 Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

Restrictive Covenants. The Indenture does not limit the issuance of debt of the Company or any of its Subsidiaries.

Denominations, Transfer and Exchange.

Indenture. This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Indenture, dated as of July 18, 2014, among Navient Corporation (the “Company”) and The Bank of New York Mellon, as trustee (herein called the “Trustee”, which term includes any successor trustee under the Indenture), as supplemented and amended by the First Supplemental Indenture, dated November 6, 2014 (as so supplemented, herein called the “Indenture”), between the Company and the Trustee, to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof, initially limited in aggregate principal amount to $            .

Optional Redemption. The Securities of this series are subject to redemption at the Company’s option, at any time and from time to time, in whole or in part, at a Redemption Price equal to the greater of (i) 100% of the principal amount to be redeemed plus accrued and unpaid interest thereon to the Redemption Date, and (ii) the sum of the present values of the remaining scheduled payments of principal and interest on the Securities to be redeemed (exclusive of interest accrued to the Redemption Date) discounted to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30 day months) at the applicable Treasury Rate (as defined below) plus 50 basis points plus accrued and unpaid interest on the principal amount being redeemed to the Redemption Date.

For purposes of determining the optional redemption price, the following definitions are applicable:

“Treasury Rate” means, with respect to any Redemption Date for the Securities, the rate per annum equal to the semi-annual equivalent yield to maturity or interpolated (on a day count basis) of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date.

The Treasury Rate will be calculated on the third business day preceding the Redemption Date.

“Comparable Treasury Issue” means the U.S. Treasury security or securities selected by an Independent Investment Banker as having an actual or interpolated maturity comparable to the remaining term of the Securities that would be utilized, 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 terms of the Securities.

“Comparable Treasury Price” means, with respect to any Redemption Date:

(c) the average of the Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or

B-4

(d) if the Independent Investment Banker is unable to obtain at least four such Reference Treasury Dealer Quotations, the average of all Reference Treasury Dealer Quotations obtained by the Independent Investment Banker.

“Independent Investment Banker” means J.P. Morgan Securities LLC and Credit Suisse Securities (USA) LLC, as specified by the Company, or if these firms are unwilling or unable to select the applicable Comparable Treasury Issue, an independent investment banking institution of national standing appointed by the Company.

‘‘Reference Treasury Dealer’’ means J.P. Morgan Securities LLC and Credit Suisse Securities (USA) LLC (and their respective successors) plus two others or their affiliates which are primary U.S. government securities dealers (each a “Primary Treasury Dealer”), provided however, that if any of the foregoing shall cease to be a Primary Treasury Dealer, the Company will substitute therefor another Primary Treasury Dealer.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any Redemption Date for the Securities, an average, as determined by the Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue for the Securities (expressed in each case as a percentage of its principal amount) quoted in writing to the Independent Investment Banker at 5:00 p.m., New York City time, on the third business day preceding such redemption date.

Notice of any redemption will be mailed at least 30 days but not more than 60 days before the redemption date to each registered holder of Securities to be redeemed. Unless the Company defaults in payment of the redemption price, on and after the redemption date, interest will cease to accrue on the Securities or portions of the Securities called for redemption. If fewer than all of the Securities are to be redeemed, the Trustee will select, not more than 60 days prior to the redemption date, the particular Securities or portions thereof for redemption from the outstanding Securities not previously called by such method as the Trustee deems fair and appropriate.

Defaults and Remedies. If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.

Repurchase Upon a Change of Control. Upon the occurrence of a Change of Control Triggering Event, the Holders of the Securities will have the right to require that the Company purchase such Holder’s outstanding Securities, in whole or in part, at a purchase price of 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to, but not including, the date of purchase.

Amendment, Modification and Waiver. The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in aggregate principal amount of the Securities at the time Outstanding of each series to be affected. The Indenture also contains provisions permitting the Holders of a

B-5

majority in aggregate principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, 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 Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

Restrictive Covenants. The Indenture does not limit the issuance of debt of the Company or any of its Subsidiaries.

Denominations, Transfer and Exchange. The Securities of this series are issuable only in registered form without coupons in denominations of $2,000 and in integral multiples of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.
