Arrangements with New Hertz	Related Party Transactions Agreements with Carl C. Icahn The Company is subject to the Nomination and Standstill Agreement, dated September 15, 2014 (the "Nomination and Standstill Agreement"), with Carl C. Icahn and certain related entities and individuals. In connection with their appointments or nomination, as applicable, to the Company’s board of directors (the "Board"), each of Hunter C. Gary, Steven D. Miller and Andrew Teno (collectively, the "Icahn Designees," and, together with Carl C. Icahn and the other parties to the Nomination and Standstill Agreements, the "Icahn Group") executed a Joinder Agreement agreeing to become bound as a party to the terms and conditions of the Nomination and Standstill Agreement (such Joinder Agreements, together with the Nomination and Standstill Agreement, are collectively referred to herein as the "Icahn Agreements"). Pursuant to the Icahn Agreements, the Icahn Designees were appointed to the Company’s Board. So long as an Icahn Designee is a member of the Board, the Board will not be expanded beyond its current size without approval from the Icahn Designees then on the Board. In addition, pursuant to the Icahn Agreements, subject to certain restrictions and requirements, the Icahn Group will have certain replacement rights in the event an Icahn Designee resigns or is otherwise unable to serve as a director (other than as a result of not being nominated by the Company for an annual meeting). In addition, until the date that no Icahn Designee is a member of the Board (or otherwise deemed to be on the Board pursuant to the terms of the Icahn Agreements), the Icahn Group agrees to vote all of its shares of the Company’s common stock in favor of the election of all of the Company’s director nominees at each annual or special meeting of the Company’s stockholders, and, subject to limited exceptions, the Icahn Group further agrees to (i) adhere to certain standstill obligations, including the obligation to not solicit proxies or consents or influence others with respect to the same, and (ii) not acquire or otherwise beneficially own more than 20% of the Company’s outstanding voting securities. Pursuant to the Icahn Agreements, the Company will not create a separate executive committee of the Board so as long as an Icahn Designee is a member of the Board. Under the Icahn Agreements, if the Icahn Group ceases to hold a “net long position,” as defined in the Nomination and Standstill Agreement, in at least 1,900,000 shares of the Company’s common stock, the Icahn Group will cause one Icahn Designee to resign from the Board; if the Icahn Group’s holdings are further reduced to specified levels, additional Icahn Designees are required to resign. In addition, pursuant to the Icahn Agreements, the Company entered into a registration rights agreement, effective June 30, 2016 (the "Registration Rights Agreement"), with certain entities related to Carl C. Icahn on behalf of any person who is a member of the "Icahn group" (as such term is defined therein) who owns applicable securities at the relevant time and is or has become a party to the Registration Rights Agreement. The Registration Rights Agreement provides for customary demand and piggyback registration rights and obligations. Arrangements with New Hertz On June 30, 2016, the Company, in its previous form as the holding company of both the existing equipment rental operations as well as the former vehicle rental operations (in its form prior to the Spin-Off, "Hertz Holdings"), completed a spin-off (the "Spin-Off") of its global vehicle rental business through a dividend to stockholders of all of the issued and outstanding common stock of Hertz Rental Car Holding Company, Inc., which was re-named Hertz Global Holdings, Inc. ("New Hertz") in connection with the Spin-Off. New Hertz is an independent public company and continues to operate its global vehicle rental business through its operating subsidiaries including The Hertz Corporation ("THC"). In connection with the Spin-Off, the Company entered into a separation and distribution agreement (the "Separation Agreement") with New Hertz. In connection therewith, the Company also entered into various other ancillary agreements with New Hertz to effect the Spin-Off and provide a framework for its relationship with New Hertz. The following summarizes some of the most significant agreements and relationships that Herc Holdings continues to have with New Hertz. Separation and Distribution Agreement The Separation Agreement sets forth the Company's agreements with New Hertz regarding the principal actions taken in connection with the Spin-Off. It also sets forth other agreements that govern aspects of the Company's relationship with New Hertz following the Spin-Off including (i) the manner in which legal matters and claims are allocated and certain liabilities are shared between the Company and New Hertz; (ii) other matters including transfers of assets and liabilities, treatment or termination of intercompany arrangements and releases of certain claims between the parties and their affiliates; (iii) mutual indemnification clauses; and (iv) allocation of Spin-Off expenses between the parties. Tax Matters Agreement The Company entered into a tax matters agreement with New Hertz that governs the parties' rights, responsibilities and obligations after the Spin-Off with respect to tax liabilities and benefits, tax attributes, tax contests and other tax matters regarding income taxes, other taxes and related tax returns.
