Confidentiality. The Executive acknowledges and agrees that the Company’s business depends to a significant degree upon the possession of information which is not generally known to others, and that the profitability of the business of the Company requires that this information remain proprietary to the Company. The Executive will not, except as required in the course of employment by the Company, disclose or use during or subsequent to the course of employment, any trade secrets or confidential or proprietary information relating to the business of the Company of which the Executive becomes aware by reason of being employed by the Company or to which the Executive gains access during his employment by the Company and which has not been publicly disclosed (other than by the Executive in breach of this provision). Such information includes client and customer lists, data, records, computer programs, manuals, processes, methods and intangible rights which are either developed by the Executive during the course of employment or to which the Executive has access. All records and equipment and other materials relating in any way to any confidential information relating to clients or to the business of the Company will be and remain the sole property of the Company during and after the end of employment. Notwithstanding the foregoing, the Executive may comply with legal process or governmental inquiry after, to the extent legally permitted, giving the Company written notice of record thereof. Upon termination of employment, the Executive will promptly return to the Company all materials and all copies or tangible embodiments of materials involving any confidential information in the Executive’s

6 CHICAGO/#2984622.14 possession or control. Provided, however, Executive may retain his address book to the extent it contains contact information and the Company shall cooperate with the Executive on the transfer of his cell phone number to Executive, if applicable. d. Agreement to be Available in Future Proceedings. During the Term and thereafter, the Executive agrees, subject to the advice of legal counsel, to voluntarily make himself reasonably available to the Company and its legal counsel, at the Company’s request, without the necessity of obtaining a subpoena or court order, in the Company’s investigation, preparation, prosecution and/or defense of any actual or potential legal proceeding, regulatory action, or internal matter. Subject to the advice of legal counsel, the Executive agrees to provide any information reasonably within the Executive’s recollection. The Executive will receive a payment of $500 per hour for cooperation services provided after the Term that are either: (i) in excess of 25 hours per month, or (ii) in excess of 100 hours on a total cumulative basis. Payment or reimbursement of the Executive’s reasonable expenses incurred in connection with activity under this subsection d. will be made by the Company promptly and in no event later than December 31 of the year following the year in which such expenses were incurred. e. Confidentiality of this Agreement. Except as required by law and as provided in Section 13.b., the Executive will not disclose the existence or terms of this Agreement to anyone except his accountants, attorneys, and spouse, and shall ensure that each such person complies with this confidentiality provision. 9. Right to Injunctive Relief. The Executive acknowledges that the Executive’s services to the Company are of a unique character which gives them a special value to the Company, the loss of which cannot reasonably or adequately be compensated in damages in an action at law, and that a breach of Section 8 of this Agreement or any restrictive covenant referenced herein will result in irreparable and continuing harm to the Company and that therefore, in addition to any other remedy which the Company may have at law or in equity, the Company will be entitled to seek injunctive relief in court (without posting of a bond) for a breach of this Agreement by the Executive. For any matter not required to be submitted to arbitration, the parties each hereby consent to exclusive jurisdiction and venue for all purposes in the state courts located in Xxxx County, Illinois, or the United States District Court for the Northern District of Illinois. 10.

Captions. The captions in this Agreement are not part of its provisions, are merely for reference and have no force or effect. If any caption is inconsistent with any provision of this Agreement, such provision will govern. j. Governing Law; Arbitration. The validity, interpretation, construction, enforcement and remedies of, or relating to, this Agreement, and the rights and obligations of the parties hereunder, will be governed by and construed in accordance with the substantive laws of the State of Illinois, without regard to the conflict of law principles, rules or statutes of any jurisdiction.

If intended for the Executive, notices will be delivered personally to the Executive’s then current residence address as shown on the Company’s records, or to

10 CHICAGO/#2984622.14 such other address as the Executive directs in a notice to the Company. All notices will be deemed to be given on the date received at the address of the addressee. l. Code Section 409A. The parties intend that this Agreement and the benefits provided hereunder be interpreted and construed to comply with Section 409A of the Internal Revenue Code of 1986, as amended, and all regulatory and interpretative guidance issued thereunder (“Code Section 409A”) to the extent applicable thereto. The time and form of payment of incentive compensation, disability benefits, severance payments, expense reimbursements and payments of in-kind benefits described herein will be made in accordance with the applicable sections of this Agreement, provided that with respect to termination of employment for reasons other than death, the payment at such time can be characterized as a “short-term deferral” for purposes of Code Section 409A or as otherwise exempt from the provisions of Code Section 409A, or if any portion of the payment cannot be so characterized, and the Executive is a “specified employee” under Code Section 409A, such portion of the payment will be delayed until the earlier to occur of the Executive’s death or the date that is six months and one day following the Executive’s termination of employment (the “Delay Period”). Upon the expiration of the Delay Period, all payments and benefits delayed pursuant to this section will be paid or reimbursed to the Executive in a lump sum, and any remaining payments due under this Agreement will be payable at the same time and in the same form as such amounts would have been paid. Further, if the Executive is a “specified employee” and if any equity-based awards granted to the Executive by the Company, pursuant to this Agreement or otherwise, continue to vest upon the Executive’s termination of employment, and are deemed a “deferral of compensation” (as such term is described under Code Section 409A), the equity- based awards will not be settled or released until the expiration of the Delay Period. For purposes of applying the provisions of Code Section 409A, each separately identifiable amount to which the Executive is entitled will be treated as a separate payment. The time or schedule of any payment or amount scheduled to be paid pursuant to the terms of this Agreement, including but not limited to any restricted stock unit or other equity-based award, payment or amount that provides for the “deferral of compensation” (as such term is described under Code Section 409A), may not be accelerated except as otherwise permitted under Code Section 409A and the guidance and Treasury regulations issued thereunder. For purposes of this Agreement, the terms “retirement,” “termination of employment,” “terminated,” “termination,” “this Agreement will be terminated” and variations thereof, as used in this Agreement, are intended to mean a termination of employment that constitutes a “separation from service” under Code Section 409A. If the sixty (60)-day period following a “separation from service” begins in one calendar year and ends in a second calendar year (a “Crossover 60-Day Period”) and if there are payments due the Executive that are subject to Code Section 409A (and not exempt from Code Section 409A) that are: (i) conditioned on the Executive signing and not revoking a release of claims and (ii) otherwise due to be paid during the portion of the Crossover 60-Day Period that falls within the first year, then such payments will be delayed and paid in a lump sum during the portion of the Crossover 60-Day Period that falls within the second year. Although the Company intends to administer the Agreement so that it will comply with the requirements of Code Section 409A, the Company does not represent or

11 CHICAGO/#2984622.14 warrant that the Agreement will comply with Code Section 409A or any other provision of federal, state, local, or non-United States law. Provided that the Company administers this Agreement in a manner consistent with the terms of this Agreement, neither the Company, its subsidiaries, nor their respective directors, officers, employees or advisers will be liable to the Executive (or any other individual claiming a benefit through the Executive) for any tax, interest, or penalties the Executive may owe as a result of compensation paid under the Agreement, and the Company and its subsidiaries will have no obligation to indemnify or otherwise protect the Executive from the obligation to pay any taxes pursuant to Code Section 409A. Payment or reimbursement of the Executive’s expenses will be made promptly and in no event later than December 31 of the year following the year in which such expenses were incurred, and the amount of such expenses eligible for payment or reimbursement, or in-kind benefits provided, in any year will not affect the amount of such expenses eligible for payment or reimbursement, or in-kind benefits to be provided, in any other year. Additionally, any right to expense reimbursement or in- kind benefits will not be subject to liquidation or exchange for another benefit. The provisions of this Agreement will be construed in a manner in favor of complying with any applicable requirements of Code Section 409A to avoid taxation under Code Section 409A. If any compensation or benefits provided by this Agreement result in the application of Code Section 409A, the Company will modify this Agreement in the least restrictive manner necessary in order to comply with the provisions of Code Section 409A, other applicable provisions of the Code and/or any rules, regulations or other regulatory guidance issued under such statutory provisions and, in each case, without material diminution in the value of the payments or benefits to the Executive.
