filed US federal, state or local income tax return for the year of exercise, vesting or settlement, as the case may be, and neither Versum nor any of its Affiliates shall take any inconsistent position in connection therewith. If, notwithstanding the foregoing, a Final Determination shall provide that the benefit of a tax deduction related to the payment of such compensation shall not belong to Air Products but to Versum, then with respect to any such compensation deduction claimed during the taxable year or years covered by such Final Determination as well as any such compensation deduction claimed during subsequent taxable years on any previously filed income tax return, Versum (i) shall be entitled to claim the benefit of the deduction on any applicable income tax return (including any amended income tax return) and (ii) shall, in any event, pay to Air Products within 30 days from the date of such Final Determination an amount equal to the incremental income tax payable by Air Products as a result of the loss of such deduction, as well as any interest payable by Air Products with respect to such incremental income tax, each as determined by Air Products in its reasonable judgment. To the extent that any Air Products Option that is subject to this Agreement has not yet been exercised, any Air Products Restricted Share that is subject to this Agreement has not vested, or any Air Products Restricted Stock Unit or Performance Share that is subject to this Agreement has not yet been settled, in each case at the time such Final Determination occurs, then to the extent that such Final Determination would be inconsistent with Air Products receiving the benefit of any tax deduction related to the payment of such compensation upon such exercise, vesting or settlement, (i) Air Products shall not claim the benefit of any associated deduction on its tax return for the year of exercise, vesting or settlement, as applicable, (ii) Versum shall be entitled to claim the benefit of the deduction on any applicable income tax return for the year of exercise, vesting or settlement and (iii) in any event, Versum shall pay to Air Products within 30 days of the such exercise, vesting or settlement an amount equal to the product of (x) the tax deduction resulting from such compensation and (y) the combined federal, state and local tax rates applicable to Air Products for the year of such exercise, vesting or settlement, in each case as determined by Air Products in its reasonable judgment.

CERTAIN PAYROLL AND TAX MATTERS

14.1 Payroll and Withholding.

(a) Accrued Payroll. Air Products shall retain all Liabilities related to payroll with respect to Versum Employees, to the extent such Liabilities relate to service prior to the Employee Transfer Date, and shall pay such amounts on or after the Employee Transfer Date in accordance with its standard payroll practices. Effective as of the Separation Time, Versum Group shall establish its own payroll system for Versum Employees.

(b) Income Reporting, Withholding. Air Products and Versum shall, to the extent practicable, (i) treat Versum (or a member of Versum Group designated by Versum) as a “successor employer” and Air Products (or the appropriate Air Products Group member) as a “predecessor,” within the meaning of Sections 3121(a)(1) and 3306(b)(1) of the Code, with respect to Versum Employees for purposes of taxes imposed under the United States Federal Unemployment Tax Act or the United States Federal Insurance Contributions Act, and (ii) cooperate with each other to avoid, to the extent possible, the filing of the more than one IRS Form W-2 with respect to each Versum Employee for the year in which the Distribution occurs. Without limiting in any manner the obligations and Liabilities of the parties under the Tax Matters Agreement, Air Products, each Air Products Group member, Versum and each Versum Group member shall each bear its responsibility for payroll tax obligations and for the proper reporting to the appropriate governmental authorities of compensation earned by their respective employees after the Employee Transfer Date, including compensation related to the exercise of options or the vesting, settlement or exercise of other equity awards, subject to Section 11.8 hereof.

(c) Delivery of, and Access to, Documents and Other Information. Concurrently with the Employee Transfer Date, Air Products shall cause to be delivered to Versum the employee information set forth on all withholding certificates executed by Versum Employees as of the Employee Transfer Date. For such period as Air Products and Versum may mutually agree in writing, Air Products shall make reasonably available to Versum all forms, documents or information, no matter in what format stored, relating to compensation or payments made to any Versum Employee. Such information may include, but is not limited to, information concerning employee payroll deductions, payroll adjustments, records of time worked, tax records (e.g., Forms W-2, 1099, W-4, 940 and 941 and applicable counterparts in other jurisdictions), and information concerning garnishment of wages or other payments.

(d) Consistency of Tax Positions; Duplication. Air Products and Versum shall individually and collectively make commercially reasonable best efforts to avoid unnecessarily duplicated federal, state or local payroll taxes, insurance or workers’ compensation contributions, or unemployment contributions arising on or after the Employee Transfer Date. Air Products and Versum shall cooperate with a view toward taking consistent reporting and withholding positions with respect to any such taxes or contributions.

14.2 Personnel and Pay Records. Notwithstanding anything to the contrary in the Separation Agreement, to the extent permitted by applicable Law, the original of all records created prior to the Employee Transfer Date set forth in the personnel files of Versum Employees (including, but not limited to, information regarding such employee’s ranking or promotions, the existence and nature of garnishment orders or other judicial or administrative actions or orders affecting the employee’s compensation, and performance evaluations) shall be transferred to the applicable member of Versum Group as of the Employee Transfer Date. The originals of all personnel records of all Former Versum Employees shall remain with the applicable member of the Air Products Group; provided that Air Products shall permit Versum or its Affiliates or successors or their authorized representatives to have full access to all such personnel records to the extent reasonably necessary in order for the members of Versum Group or its successors to respond to a subpoena, court order, audit, investigation or otherwise as required by applicable Law or in connection with any pending or threatened lawsuits, actions, arbitrations, claims, complaints, investigations or other proceedings. Versum or its Affiliates (or their respective successors) shall retain the personnel records for a period of at least ten (10) years following the Distribution. The members of Versum Group shall permit Air Products and its authorized representatives to have full access upon reasonable notice during normal business hours to all the personnel records during the ten (10) year retention period in order for the members of the Air Products Group to respond to a subpoena, court order, audit or investigation, to obtain data for pension or other benefits, or otherwise as required by applicable Law, and the members of Versum Group shall provide Air Products, upon the reasonable request of Air Products and at the expense of Air Products, with copies of such personnel records.
