|   | • | **Termination without   Cause:     **If during the   first two years of your employment with the Company your employment is   terminated without “cause”, as defined herein, then upon execution of a   general release of claims satisfactory to the Company, the Company will   provide you with the following severance benefits:  six months of salary continuation at your then current rate of   base salary, and twelve months of employer-paid group health benefits on the   same basis as active employees.  If at   any time while you are receiving severance benefits from 724 Solutions you   commence employment elsewhere (to be determined in the discretion of the   Board of Directors) then your severance benefits as described above will   cease at that time.    Except as may   be provided under this Agreement following termination of your employment (i)   any benefits to which you may be entitled pursuant to theCompany plans,   policies and arrangements referred to above shall be determined and paid in   accordance with the terms of such plans, policies and arrangements, and (ii)   you shall have no right to receive any other compensation, or to participate   in any other plan, arrangement or benefit, with respect to future periods   after such termination.  For purposes   of this document “Termination without Cause” includes the Company decreasing   your base salary to an amount less than 95% of your starting annual base   salary, $175,000, without your approval, and/or significantly changing your   position or the scope of your responsibilities without your consent and   approval.  Should you believe that the   scope of your responsibilities has changed significantly, you must document   the reasons you believe such in a written letter delivered to an Officer of   724 Solutions, and allow 724 Solutions to rectify such within 30 days. |

|   | • | **Definition of “Cause:     **“Cause”   shall mean: (i) the Executive’s death or her permanent disability, which   shall mean the Executive’s inability, as a result of physical or mental   incapacity, substantially to perform her duties hereunder for a period of   three (3) consecutive months; (ii) a material violation by the Executive of   any applicable material law or regulation respecting the business of the   Employer; (iii) the Executive being found guilty of criminal misconduct, or   (iv) the Executive perpetrating an act of dishonesty, , or (v) the   intentional negligent failure of the Executive to perform her duties   hereunder in any material respect.  The Executive shall be entitled to   at least ten (10) days’ prior written notice of the Employer’s intention to   terminate her employment for “Cause” (as defined herein) (except the   Executive’s death or conviction of afelony) specifying the grounds for such   termination, and a reasonable opportunity to cure any conduct or act, if   curable, alleged as grounds for such termination, and a reasonable   opportunity to present to a representative the Board her position regarding   any dispute relating to the existence of such cause.  In the event   termination is based upon a claim of physical or mental incapacity, and a   dispute regarding the Executive’s disability arises between the Executive and   the Employer, each party shall choose a physician who together will choose a   third physician to make a final determination.                                                                                                                                                                                                                                                                                                                                                   |
