This Letter shall become effective on the date that the Closing occurs (the “Effective Date”).

• “Cause” means any of the following: (i) your commission of gross misconduct in connection with the performance of any of your duties; (ii) your engagement in, or attempt to engage in, acts or omissions constituting fraud, misappropriation, embezzlement, intentional wrongdoing or dishonesty (but excluding expense reimbursement disputes as to which you had a reasonable good faith belief that your conduct was in compliance with the policies of Vantiv and its subsidiaries, including the Company, that are applicable to you); (iii) your willful failure to implement reasonable directives of direct supervisor after written notice of such failure is delivered to you, which failure is not corrected within ten (10) days following delivery of such written notice; (iv) your material breach of the policies or procedures of Vantiv and its subsidiaries, including the Company, governing business ethics applicable to executives similarly situated to you (as may be amended from time to time); (v) your conviction of, or plea of guilty or no contest to, a felony; or (vi) your material breach in the performance of your obligations under this Letter, which breach is not corrected within ten (10) days following delivery to you of written notice describing such breach.

• “Good Reason” means the occurrence of any of the following events without your written consent: (i) the assignment to you of duties materially inconsistent with your title as set forth in this Letter; provided, that Good Reason shall not exist pursuant to this clause (i) if, after a change of control of Vantiv as defined in the Vantiv, Inc. 2012 Equity Incentive Plan or any successor plan (a “Change of Control”), you are performing substantially the same duties as before the Change of Control but Vantiv (or its successors) is part of a larger organization, or you are performing such duties for a business unit of a parent entity that is a larger organization than Vantiv was before such Change of Control; (ii) a material breach by Vantiv in performing any of its obligations under this Letter; (iii) a requirement that you permanently relocate your principal place of employment to a geographic area more than fifty (50) miles from your principal place of employment as of the Effective Date; (iv) a material diminution of your Base Salary or target bonus opportunity as set forth in this Letter, other than as part of an across-the-board reduction that results in a proportional reduction to you substantially equivalent to that of other senior executives that are designated at the same level of participation as you are under the Severance Plan; or (v) any requirement imposed by Vantiv that you take any action or omit to take any action, which if taken or omitted to be taken would require you to resign in order to comply with applicable law. Notwithstanding the forgoing, in no event shall Good Reason be deemed to exist unless within sixty (60) days following the occurrence of any of the events set forth in clauses (i) through (v), you shall have delivered a written notice to Vantiv indicating your intention to terminate your employment for Good Reason, which written notice specifies in reasonable detail the circumstances claimed to give rise to your right to terminate employment for Good Reason, and Vantiv shall not have cured such circumstances within thirty (30) days following Vantiv’s receipt of such written notice (in which event such termination shall be effective upon the expiration of such thirty (30) day period). For the avoidance of doubt, any change to your title, position, duties, authority or reporting from those in effect prior to the Effective Date, and any change to

Section 409A

Six Month Delay. For purposes of this Letter, all references to “termination of employment” shall be deemed to refer to a “separation from service” as defined in Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”). If and to the extent any portion of any payment, compensation or other benefit provided to you under this Letter by reason of your termination of employment is determined to constitute “nonqualified deferred compensation” within the meaning of Section 409A for which no exemption is available and you are a specified employee as defined in Section 409A(a)(2)(B)(i) of the Code, as determined by Vantiv in accordance with its procedures, by which determination you hereby agree that you are bound, such portion of the payment, compensation or other benefit will be paid within ten (10) days following the earlier of (i) the day that is six (6) months plus one (1) day after the date of the termination of employment or (ii) the date of your death (as applicable, the “New Payment Date”). The aggregate of any payments that otherwise would have been paid to you during the period between the date of separation from service and the New Payment Date will be paid to you in a lump sum in the first payroll period beginning after such New Payment Date, and any remaining payments will be paid on their original schedule.

General Purposes. For purposes of this Letter, each amount to be paid or benefit to be provided will be construed as a separate identified payment for purposes of Section 409A, and any payments that are due within the “short term deferral period” as defined in Section 409A or are paid in a manner covered by Treas. Reg. Section 1.409A-1(b)(9)(iii) will not be treated as deferred compensation unless applicable law requires otherwise. Neither the Vantiv Group nor you will have the right to accelerate or defer the delivery of any such payments or benefits except to the extent specifically permitted or required by Section 409A. The payments and benefits provided pursuant to this Letter are intended to comply with, or be exempt from, the provisions of Section 409A and the terms of this Letter will be administered and construed in accordance with such intention. In any event, the Vantiv Group makes no representation or warranty and will have no liability to you or any other person if any penalties are imposed under Section 409A with respect to the payments and benefits provided pursuant to this Letter.

At-Will Employment

Your employment with the Vantiv Group is on an at-will basis and no part of this Letter should be construed as a contract or guarantee of continued employment for any period of time. Either the Vantiv Group or you may terminate your employment at any time, for any reason or no reason, and with or without notice. No statement in this Letter or otherwise should be considered to change the status of your employment from at-will employment, unless it is made in writing and signed by the Chief Executive Officer of Vantiv (or his designee).
