SEPARATION AGREEMENT AND GENERAL RELEASE

This Separation Agreement and General Release (the "Release" or “Agreement”) is made and entered into by and between MB Financial Bank N.A. (the "Company") and Larry J. Kallembach (the "Employee").

FOR VALUABLE CONSIDERATION, the receipt and sufficiency of which is hereby acknowledged, the parties agree as follows:

1.Separation of Employment. Effective the close of business on October 24, 2014 (the “Separation Date”), the Employee and the Company agree that the Employee’s employment with the Company permanently ended for the business reasons previously reviewed with Employee. The Employee agrees that Employee will not hereinafter seek reinstatement, recall or re-employment with the Company and the Employee acknowledges that the Company is not obligated to process an employment application submitted by Employee in the future.

2.Final Pay and Employee Benefits. Regardless of whether Employee signs this Release, on or before the next regular pay date following the Separation Date, the Company will pay Employee his/her wages or salary earned through the Separation Date and Employee’s earned but unused vacation hours, if any, less all legally required withholdings. Employee shall be entitled to receive Employee’s account balance, if any, under the Company’s 401(k) Profit Sharing Plan in accordance with the terms of such Plan.

3.Equity Grants. Employee’s separation from employment is an “involuntary termination without Cause” for purposes of Employee’s outstanding equity grants. The vesting, exercise and payment terms for such outstanding equity grants shall be determined in accordance with the terms of the applicable grant agreements; provided that the Employee’s Incentive Stock Option awards with grant dates of August 29, 2012 and August 29, 2013 shall vest in full on the Separation Date and remain exercisable for one year after the Separation Date.

4.Separation Payments and Benefits. As consideration for the Employee to enter, comply with and not revoke this Release and to assist the Employee in their transition to alternate employment, the Company shall provide the Employee the following separation payments and benefits:

(a)As a “Separation Payment” to assist the Employee in his/her transition to alternate employment, the Company shall pay the Employee the sum of $808,893.00 on the first regular payroll date occurring after the Separation Date, after the expiration of the seven (7) day revocation period described in Paragraph 13 below and after Employee has signed this Release. This payment represents two (2) years of Employee’s regular base pay of $263,000 (a total of $526,000.00) and two (2) years of Employee’s average annual bonus ($141,446.50) (a total of $282,893.00). All

payments made hereunder shall be subject to all applicable withholding and other employment taxes. Employee agrees that he is solely responsible for all income and other taxes associated with the Separation Payment.

(b)One-fourth (¼) of the Separation Payment hereunder shall be in consideration of the release of any claim under the Age Discrimination in Employment Act of 1967, as amended, and as described in Paragraph 4 hereof, and the Employee agrees that such consideration is in addition to anything of value to which Employee is already entitled. The remainder of the separation payment shall be in consideration of both the release of all other claims described below in Paragraph 5, the promise not to file a lawsuit in Paragraph 6, and the Protective Agreement described in Paragraph 8.

(c)No other sums (contingent or otherwise) shall be paid to the Employee with respect of his/her employment by the Company. Employee further acknowledges that by entering into this Release, Employee is receiving more money, compensation and benefits than Employee would otherwise be entitled to receive from the Company.

(d)Provided the Employee makes a timely COBRA election and subject to the restrictions described herein, the Company shall continue to provide the Employee and his dependents with medical, dental, or other health benefits (subject to the terms and conditions set forth in such benefit programs) at the same premium cost to the Employee and at the same coverage level as in effect as of the Employee’s Separation Date until the second anniversary of the Separation Date, without regard to the federal income tax consequences of that continuation. The benefits provided under this subsection (d) will be discontinued prior to the end of the second anniversary of the Separation Date if the Employee receives substantially similar benefits in the aggregate from a subsequent employer. Additionally, the period of continued medical, dental and other health benefits will count towards any COBRA continuation coverage period that may apply to the Employee. The Company or its designee will provide the Employee with a document that describes the Employee’s right to elect COBRA coverage and his rights and obligations under the COBRA laws.

(e)    To further assist in the transition to alternate employment, the Employee will be eligible to receive outplacement services at an outplacement company and level of outplacement services to be determined by the Company, provided that the Employee begins to use such services within six (6) months of the Separation Date and otherwise complies with this Agreement and the Company's applicable outplacement contract.

5.    General Release. As a material inducement to the Company to enter into this Agreement and in consideration of the payments to be made by the Company to the Employee in Paragraph 3 above, the Employee, with full understanding of the contents and legal effect of this Release and having the right and opportunity to consult with his counsel, releases and discharges MB Financial, Inc., the Company, and each of their subsidiaries, affiliates and related entities of any kind, each of their respective shareholders, officers, directors, supervisors, members, managers, employees, agents, representatives, attorneys, and its and their predecessors, successors, heirs, executors, administrators, and assigns (collectively, the "Released Parties") from any and all claims, actions, causes of action, grievances, suits,

or complaints of any kind or nature whatsoever, that he ever had or now has, whether fixed or contingent, liquidated or unliquidated, known or unknown, suspected or unsuspected, and whether arising in tort, contract, statute, or equity.
