WHEREAS, Executive has served on the Company’s Board of Directors as a registered director of the Company;

WHEREAS, the Company and Executive have agreed that Executive’s service with the Company is being terminated effective on February 24, 2015 (the “Separation Date”);

WHEREAS, the Executive and the Company desire to settle fully and finally all matters between them to date, including, but in no way limited to, any issues that might arise out of the Executive’s service with or his resignation from the Company;

NOW THEREFORE, in consideration of the promises made herein, the Parties hereby agree as follows:

2.Consideration.

3.Stock. There will be no changes to terms of Executive’s outstanding equity awards. As of the Separation Date, Executive has 31,250 vested and outstanding stock options (“Option”), with the remaining unvested being forfeited upon termination. The vested Options must be exercised within a specified period of time following the Separation Date, as set forth in the applicable Stock Option Award Agreement dated September 9, 2013. Options not exercised by the specified date are forfeit. The remaining 1,060 unvested shares of restricted stock granted pursuant to the Restricted Stock Award

Agreement dated February 14, 2011 will vest upon your termination of employment (which shall constitute your “Retirement” as defined in the Company’s Amended and Restated 2007 Equity Incentive Plan) in accordance with the terms of the applicable award agreement. The 13,125 unvested shares of restricted stock granted pursuant to the Restricted Stock Award Agreement dated November 1, 2012 will be forfeited upon termination.

4.Benefits. Executive’s participation in all benefits and incidents of service (including, but not limited to, the accrual of vacation and paid time off, use of Company car, and club memberships) ceased on the Separation Date. The Company will pay for or provide for continued coverage under existing healthcare plans through December 31, 2015. The Company will also provide Executive with tax return preparation and filing assistance for any year in which Executive served as a US ex-patriate, including 2014.

5.Payment of Salary. Executive acknowledges and represents that Executive has been paid all salary, wages, accrued vacation, paid time off, bonuses, commissions, and any and all other benefits and compensation due to Executive from Company, Parent and any of their affiliates.

6.Release of Claims. Executive agrees that the foregoing Consideration represents settlement in full of all outstanding obligations owed to Executive by the Company, Parent and their respective current and former officers, directors, employees, agents, investors, attorneys, shareholders, administrators, affiliates, divisions, subsidiaries, predecessor and successor corporations and assigns (the “Releasees”). Executive, on his own behalf, and on behalf of his respective heirs, family members, executors, agents, and assigns, hereby fully and forever releases the Company, Parent and the other Releasees from, and agrees not to sue concerning, any claim, duty, obligation or cause of action relating to any matters of any kind, whether presently known or unknown, suspected or unsuspected, that Executive may possess arising from any cause, matter, omissions, acts or facts whatsoever including, without limitation:

(b)any and all claims under the law of any jurisdiction, including, but not limited to, wrongful termination of service; constructive termination from service; termination of the service in violation of public policy; discrimination; breach of contract, both express and implied; breach of a covenant of good faith and fair dealing, both express and implied; negligent or intentional infliction of emotional distress; negligent or intentional misrepresentation; negligent or intentional interference with contract or prospective economic advantage; unfair business practices; defamation; libel; slander; negligence; personal injury; assault; battery; invasion of privacy; false imprisonment; and conversion;

(c)any and all claims arising out of any constitution, laws and regulations including, without limitation, any such constitution, laws or regulations relating to service;

(d)any claim for any loss, cost, damage, or expense arising out of any dispute over the non-withholding or other tax treatment of any of the proceeds received by Executive as a result of this Agreement; and

(e)any and all claims for attorneys’ fees and costs.

The Company and Executive agree that the release set forth in this section shall be and remain in effect in all respects as a complete general release as to the matters released. This release does not extend to any obligations incurred under this Agreement.

7.Confidential Information. Executive recognizes that due to his service, Executive has had access to non-public proprietary information, confidential information and trade secrets. Consequently, at all times after the Separation Date Executive will not, without the prior express written consent of the Company, use for himself or for others or directly or indirectly divulge, disclose or make available or accessible any Confidential Information (as defined below) to any person, firm, partnership, corporation, trust or any other entity or third party (other than when required to do so by a lawful order of a court of competent jurisdiction, any governmental authority or agency, or any recognized subpoena power). For purposes of this Agreement, “Confidential Information” shall mean all information respecting the business and activities of the Company, Parent, or any of their affiliates, including, without limitation, the clients, customers, suppliers, employees, consultants, computer or other files, projects, products, computer disks or other media, computer hardware or computer software programs, marketing plans, financial information, methodologies, know-how, processes, practices, approaches, projections, forecasts, formats, systems, data gathering methods and/or strategies of the Company, Parent, or any of their affiliates. Notwithstanding the immediately preceding sentence, Confidential Information shall not include any information that is, or becomes, generally available to the public (unless such availability occurs as a result of the Executive’s breach of any portion of this Section 7). Executive will use particular care to ensure that such Confidential Information does not become known to those who are engaged in activities competitive with those of the Company, Parent, or any of their affiliates. In addition, Executive represents, warrants and agrees that he is in compliance with the Parent’s Code of Business Conduct.

This section will not prevent either party from seeking injunctive relief (or any other provisional remedy) from any court having jurisdiction over the Parties and the subject matter of their dispute relating to Executive’s obligations under this Agreement and any agreements incorporated herein by reference.

Executive acknowledges that a breach by Executive of the obligations set forth in Sections 6, 7, 8, 10 and 11 above will result in irreparable harm, and no adequate remedy at law exists. Such breach will be deemed "material", entitling the Company to money damages and other appropriate relief including reimbursement of costs, reasonable attorneys' fees and an injunction to prevent any further breach of this Agreement.

IN WITNESS WHEREOF, the Parties have executed this Agreement on the dates set forth below.
