FIRST SUPPLEMENTAL INDENTURE, dated as of June 9, 2016 (this “Supplemental Indenture”), among Herc Spinoff Escrow Issuer, LLC (the “Company”) and Herc Spinoff Escrow Issuer, Corp. (together with the Company and each of their respective successors and assigns, the “Issuers”), as co-issuers and Wilmington Trust, National Association, as Trustee and Note Collateral Agent.

WHEREAS, the Issuers, the Trustee and the Note Collateral Agent are party to the Indenture, dated as of June 9, 2016 (as amended, supplemented or otherwise modified from time to time, the “Indenture”), which provides for the issuance from time to time of Notes by the Issuers;

1. Defined Terms. As used in this Supplemental Indenture, terms defined in the Indenture or in the preamble or recital hereto are used herein as so defined. The words “herein,” “hereof” and “hereby” and other words of similar import used in this Supplemental Indenture refer to this Supplemental Indenture as a whole and not to any particular section hereof.

“Mandatory Redemption Event” means (i) 5:00 p.m. (New York City time) on the then applicable Outside Date, if (and only if) the Escrow Agent has not received an Escrow Officer’s Certificate at or prior to such time, or (ii) the receipt by the Escrow Agent of an Escrow Termination Notice from the Company prior to the then applicable Outside Date.

“Special Mandatory Redemption Price” means a price equal to 100.0% of the initial issue price of the Notes plus accrued and unpaid interest on the Notes, if any, as calculated in accordance with the terms of the Indenture and the Notes, from and including the Issue Date to, but excluding, the Special Mandatory Redemption Date.

4. Interest and Interest Rates. Interest on the Outstanding principal amount of 2022 Notes will accrue at the rate of 7.50% per annum and will be payable semi-annually in arrears on June 1 and December 1 in each year, commencing on December 1, 2016, to holders of record on the immediately preceding May 15 and November 15, respectively (each such May 15 and November 15, a “Regular Record Date”). Interest on the 2022 Notes will accrue from the most recent date to which interest has been paid or provided for or, if no interest has been paid, from June 9, 2016, except that interest on any Additional 2022 Notes (as defined below) issued on or after the first Interest Payment Date will accrue (or will be deemed to have accrued) from the most recent date to which interest has been paid or duly provided for or, if no interest has been paid on such Additional 2022 Notes, from the Interest Payment Date immediately preceding the date of issuance of such Additional 2022 Notes (or if the date of issuance of such Additional 2022 Notes is an Interest Payment Date, from such date of issuance); provided that if any 2022 Note issued in exchange therefor is surrendered for exchange on or after a record date for an Interest Payment Date that will occur on or after the date of such exchange, interest on such Note received in exchange thereof will accrue from such Interest Payment Date.

5. No Limitation on Aggregate Principal Amount. The aggregate principal amount of 2022 Notes that may be authenticated and delivered and Outstanding under the Indenture is not limited. The aggregate principal amount of the 2022 Notes shall initially be $610.0 million. Subject to Sections 407 and 413 of the Indenture, the Issuers may from time to time, without the consent of the Holders, create and issue Additional Notes having the same terms and conditions as the 2022 Notes in all respects or in all respects

except for issue date, issue price and, if applicable, the first date on which interest accrues and the first payment of interest thereon. Additional Notes issued in this manner will be consolidated with, and will form a single series with, the 2022 Notes (any such Additional Notes, “Additional 2022 Notes”), unless otherwise specified for Additional Notes in an applicable Notes Supplemental Indenture, or otherwise designated by the Company, as contemplated by Section 301 of the Indenture.

6. Redemption. (a) The 2022 Notes will be redeemable, at the Company’s option, in whole or in part, at any time and from time to time on and after June 1, 2019 and prior to maturity thereof at the applicable redemption price set forth below. The 2022 Notes will be so redeemable at the following redemption prices (expressed as a percentage of principal amount), plus accrued and unpaid interest, if any, to, but not including, the relevant Redemption Date (subject to the right of Holders of record on the relevant Regular Record Date to receive interest due on the relevant Interest Payment Date falling prior to or on the Redemption Date pursuant to Section 307 of the Indenture), if redeemed during the 12-month period commencing on June 1 of the years set forth below:

(b) In addition, during any 12‑month period prior to June 1, 2019, the Company will be entitled to redeem up to 10.0% of the original aggregate principal amount of the 2022 Notes (including the principal amount of any Additional Notes of the same series) at a redemption price equal to 103.000% of the aggregate principal amount thereof, plus accrued and unpaid interest thereon, if any, to, but not including, the Redemption Date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date falling prior to or on the Redemption Date).

(c) In addition, at any time and from time to time on or prior to June 1, 2019, the Company at its option may redeem 2022 Notes in an aggregate principal amount equal to up to 40.0% of the original aggregate principal amount of the Notes (including the principal amount of any Additional 2022 Notes, or any other Additional Notes of the same series as the 2022 Notes), with funds in an equal aggregate amount (the “Redemption Amount”) not exceeding the aggregate proceeds of one or more Equity Offerings, at a redemption price (expressed as a percentage of principal amount thereof) of 107.50% plus accrued and unpaid interest, if any, to the Redemption Date (subject to the right of Holders of record on the relevant Regular Record Date to receive interest due

on the relevant Interest Payment Date falling prior to or on the Redemption Date pursuant to Section 307 of the Indenture); provided, however, that an aggregate principal amount of 2022 Notes equal to at least 50.0% of the original aggregate principal amount of 2022 Notes (including the principal amount of any Additional 2022 Notes, or any other Additional Notes of the same series as the 2022 Notes) must remain outstanding immediately after each such redemption. Any amount payable pursuant to this Section 6(c) may be funded from any source (including amounts in excess of the Redemption Amount).

(d) At any time prior to June 1, 2019, 2022 Notes may also be redeemed or purchased (by the Company or any other person) in whole or in part, at the Company’s option, at a price (the “Redemption Price”) equal to 100.0% of the principal amount thereof plus the Applicable Premium (as defined below) as of, and accrued but unpaid interest, if any, to, but not including, the Redemption Date (subject to the right of Holders of record on the relevant Regular Record Date to receive interest due on the relevant Interest Payment Date falling prior to or on the Redemption Date pursuant to Section 307 of the Indenture).

“Applicable Premium” means, with respect to a 2022 Note at any Redemption Date, the greater of (i) 1.00% of the principal amount of such 2022 Note and (ii) the excess of (A) the present value at such Redemption Date, calculated as of the date of the applicable redemption notice, of (1) the redemption price of such 2022 Note on June 1, 2019 (such redemption price being that described in Section 6(a)), plus (2) all required remaining scheduled interest payments due on such 2022 Note through such date (excluding accrued and unpaid interest to the Redemption Date), computed using a discount rate equal to the Treasury Rate plus 50 basis points, over (B) the principal amount of such 2022 Note on such Redemption Date, as calculated by the Company or on behalf of the Company by such Person as the Company shall designate; provided that such calculation shall not be a duty or obligation of the Trustee.

“Treasury Rate” means, with respect to a Redemption Date, the weekly average yield to maturity at the time of computation of United States Treasury securities with a constant maturity (as compiled and published in the most recent Federal Reserve Statistical Release H.15(519) that has become publicly available at least two Business Days prior to the date of the applicable redemption notice (or, if such Statistical Release is no longer published, any publicly available source of similar market data)) most nearly equal to the period from such Redemption Date to June 1, 2019, provided, however, that if the period from the Redemption Date to such date is not equal to the constant maturity of a United States Treasury security for which a weekly average yield is given, the Treasury Rate shall be obtained by linear interpolation (calculated to the nearest one-twelfth of a year) from the weekly average yields of United States Treasury securities for which such yields are given, except that if the period from the Redemption Date to such

(e) Notwithstanding clauses (a), (b), (c) and (d) of this Section 6, in connection with any tender for the 2022 Notes, if Holders of not less than 90% in the aggregate principal amount of the outstanding 2022 Notes (including the principal amount of any Additional 2022 Notes, or any other Additional Notes of the same series as the 2022 Notes) validly tender and do not withdraw such Notes in such tender offer and the Company, or any other Person making such tender offer, purchases all of the 2022 Notes (including any Additional 2022 Notes and any Additional Notes of the same series as the 2022 Notes) validly tendered and not withdrawn by such Holders, the Company will have the right, upon notice given not more than 30 days following such purchase pursuant to such tender offer, to redeem all of the 2022 Notes that remain outstanding following such purchase at a price in cash equal to the price offered to each Holder in such tender offer, plus, to the extent not included in the tender offer payment, accrued and unpaid interest to but excluding the Redemption Date.

(f) Any redemption of Notes pursuant to this Section 6 may be made upon notice sent electronically or, at the Company’s option, mailed by first-class mail to each Holder’s registered address in accordance with Section 1005 of the Indenture, and, if applicable, the Company should notify the Trustee of such redemption date, and the principal amount of Notes to be redeemed in accordance with Section 1003 of the Indenture. The Company may provide in any redemption notice that payment of the redemption price and the performance of the Issuers’ obligations with respect to such redemption may be performed by another Person.

(g) Any redemption of Notes pursuant to this Section 6 (including in connection with an Equity Offering) or notice thereof may, at the Company’s discretion, be subject to the satisfaction (or, waiver by the Company in its sole discretion) of one or more conditions precedent, which may include consummation of any related Equity Offering or the occurrence of a Change of Control. If such redemption or notice is subject to satisfaction of one or more conditions precedent, such notice may state that, in the Company’s discretion, the Redemption Date may be delayed until such time as any or all such conditions shall be satisfied (or waived by the Company in its sole discretion), or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been (or, in the Company’s sole determination, may not be) satisfied (or waived by the Company in its sole discretion) by the Redemption Date, or by the Redemption Date so delayed.

(i) Upon the occurrence of a Mandatory Redemption Event, the Company will redeem all and not less than all of the Notes at the Special Mandatory Redemption Price, with notice of such redemption to be provided as described in Section 6(h)(ii) below. Such redemption (the “Special Mandatory Redemption”) shall be made in accordance with the terms of the Escrow Agreement and for purposes of a Special Mandatory Redemption, the Company shall not be subject to the provisions of Section 1006 of the Indenture.

(ii) The Company will deliver to the Trustee and the Escrow Agent notice of the occurrence of a Mandatory Redemption Event (a “Special Redemption Company Notice”), within three Business Days following the occurrence thereof. Concurrently with the delivery of the Special Redemption Company Notice, the Company will request the Trustee to, at the Company’s expense, deliver a notice prepared by the Company that a Special Mandatory Redemption is to occur (a “Special Redemption Trustee Notice”) and will notify the Trustee and the Escrow Agent of the Redemption Date (the “Special Mandatory Redemption Date”), which date shall be no later than three Business Days after the date of delivery of the Special Redemption Company Notice. Upon the receipt by the Trustee of a Special Redemption Company Notice, the Trustee shall promptly (and in any event within one Business Day) mail to each Holder a Special Redemption Trustee Notice. The Special Redemption Trustee Notice shall set forth the information provided in Section 1005 of the Indenture. The Company will perform the Special Mandatory Redemption on the Special Mandatory Redemption Date.
