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, High River Limited Partnership, Hopper Investments LLC, Barberry Corp., Icahn Partners LP, Icahn Partners Master Fund LP, Icahn Enterprises G.P. Inc., Icahn Enterprises Holdings L.P., IPH GP LLC, Icahn Capital LP, Icahn Onshore LP, Icahn Offshore LP, Beckton Corp., Vincent J. Intrieri, Samuel Merksamer and Daniel A. Ninivaggi (collectively, the "Original Icahn Group"). In connection with their appointments or nomination, as applicable, to the Company’s board of directors (the "Board"), each of Courtney Mather, Louis J. Pastor, Stephen A. Mongillo and Nicholas F. Graziano (collectively, the "Icahn Designees," and, together with the Original Icahn Group, 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, Messrs, Mather, Pastor and Mongillo were appointed to the Company’s Board effective June 30, 2016 and Mr. Graziano was elected to the Board at the Company's 2018 annual meeting of stockholders in place of Mr. Mongillo. Pursuant to the Icahn Agreements, so long as an Icahn Designee is a member of the Board, the Board will not be expanded beyond its current size of 11 members 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 “Board Representation Period”), 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. 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 High River Limited Partnership, Icahn Partners LP and Icahn Partners Master Fund LP, 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 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. Transition Services Agreement The Company entered into a transition services agreement ("TSA"), pursuant to which New Hertz or its affiliates provided, during the three and six months ended June 30, 2018, specified services, primarily consisting of IT support, to the Company on a transitional basis to help ensure an orderly transition following the Spin-Off. Effective upon the migration of the Company’s financial systems from the New Hertz system to a stand-alone system in July 2018, the Company receives no further services from New Hertz under the TSA. During the three and six months ended June 30, 2018, the Company incurred expenses of $2.8 million and $5.7 million, respectively, under the TSA which are included in "Direct operating" and "Selling, general and administrative" expenses in the Company's condensed consolidated statements of operations, compared to $4.9 million and $10.1 million for the same periods in 2017. Tax Matters Agreement The Company entered into a tax matters agreement (the "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. Employee Matters Agreement The Company and New Hertz entered into an employee matters agreement to allocate liabilities and responsibilities relating to employment matters, employee compensation, benefit plans and programs and other related matters for current and former employees of the vehicle rental business and the equipment rental business. Intellectual Property Agreement The Company and New Hertz entered into an intellectual property agreement (the “Intellectual Property Agreement”) that provides for ownership, licensing and other arrangements regarding the trademarks and related intellectual property that New Hertz and the Company use in conducting their businesses. The Intellectual Property Agreement allocates ownership between New Hertz and the Company of all trademarks, domain names and certain copyrights that Hertz Holdings or its subsidiaries owned immediately prior to the Spin-Off. Real Estate Arrangements The Company and New Hertz entered into certain real estate lease agreements pursuant to which the Company leased certain office space from New Hertz through June 30, 2018 and New Hertz leased certain rental facilities space from the Company, through April 30, 2018. Rent payments were negotiated based on comparable fair market rental rates.
