SEVERANCE AGREEMENT AND RELEASE

This Severance Agreement and Release (“Agreement”) is made by and between Gaylan Larson (“Employee”) and Notify Technology Corporation, a California corporation (“Company”) (collectively referred to as the “Parties”):

WHEREAS, Employee was employed by the Company pursuant to an employment agreement dated as of November 4, 2002 (the “Employment Agreement”);

WHEREAS, the Company and Employee entered into a Employee Confidentiality and Inventions Assignment Agreement dated as of October 24, 1994 (the “Confidentiality Agreement”);

WHEREAS, the Company and Employee have entered into Stock Option Agreements as listed below granting Employee the option to purchase shares of the Company’s Common Stock subject to the terms and conditions of the Company’s 1997 Stock Plan and a related Stock Option Agreement (collectively, the “Stock Agreements”);

WHEREAS, Employee’s employment with Company was terminated as of September 30, 2004 (the “Termination Date”);

WHEREAS, the Parties, and each of them, wish to resolve any and all disputes, claims, complaints, grievances, charges, actions, petitions and demands that the Employee may have against the Company as defined herein, including, but not limited to, any and all claims arising or in any way related to Employee’s employment with, or separation from, the Company.

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

COVENANTS

1. Resignation. Employee hereby resigns, effective as of the Termination Date, as an officer and employee of the Company and from any and all other positions Employee holds with the Company and any subsidiary or affiliated entity of the Company.

-1-

2. Consideration.

(a) Additional Payments. The Company agrees to pay Employee at the rate of Eight Thousand Dollars ($8,000.00) per month, less applicable withholding, for three months from the first regular payroll date following the Effective Date (the “Payment Period”) in accordance with the Company’s regular payroll practices.

(b) No Other Payments. Other than the Company’s obligations under this Agreement, Employee shall not be entitled to any other wages, salaries, bonuses, compensation or other form of payment pursuant to the Employment Agreement or any other agreement between Company and Employee.

(c) Stock Vesting. The Parties agree that for purposes of determining the number of shares of the Company’s Common Stock that Employee is entitled to purchase from the Company pursuant to the exercise of outstanding options, the Employee will be considered to have vested only up to the Termination Date. Employee acknowledges that, as of the Termination Date, he will have vested in, and be entitled to exercise and acquire, an aggregate of 298,611 shares of Common Stock under the Stock Agreements (excluding the 2003 Option discussed in Section 1(d) below). The exercise of any stock options (other than those discussed in Section 1(d)) shall continue to be subject to the terms and conditions of the respective Stock Agreements, and in accordance with the foregoing shall be exercisable for a period of 90 days from the Termination Date as follows:

(d) Acceleration; Special Bonus; Option to Exercise. The Company agrees to accelerate vesting with respect to all unvested shares subject to Option Number N190 0803, dated August 6, 2003 (the “2003 Option”), such that the 2003 Option will be immediately exercisable for all shares of Common Stock issuable upon exercise thereof. In addition, on the Effective Date (as defined in Section 25), the Company will pay Employee a one-time bonus of $41,875.00, subject to applicable withholding (the “Special Bonus”), provided, however, that Employee has elected to exercise the 2003 Option for all shares issuable upon exercise thereof on or before 5:00 p.m. (California time) on the Effective Date. In the event of Employee’s election to exercise the 2003 Option, Employee hereby authorizes and directs the Company to withhold from the Special Bonus an amount totaling $31,205.00, representing Employee’s payment of the aggregate exercise price therefor. Employee acknowledges and agrees that in the event he has not, prior to 5:00 p.m. (California Time) on the Effective Date, taken all actions necessary to exercise the 2003 Option in accordance with the applicable Stock Agreement (other than delivery of the purchase price therefor, which will be withheld from the Special Bonus), then the Company’s obligation to pay the Special Bonus shall immediately expire with no further force or effect.

-2-

(e) COBRA; Benefits; Reimbursement. Employee’s Company-sponsored health insurance benefits will cease on the Termination Date. Employee and each eligible dependent who constitutes a qualified beneficiary, as defined in Section 4980B(g)(1) of the Internal Revenue Code of 1986, as amended, will be eligible to continue coverage under the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”), within the time period prescribed pursuant to COBRA. Employee acknowledges that the Company has provided him with information concerning his obligations and time requirements to secure COBRA benefits. Should Employee elect to purchase insurance coverage pursuant to COBRA, the Company shall reimburse Employee for up to three (3) months of Employee’s COBRA payment obligation upon Employee’s delivery of evidence of payment therefor. Employee agrees that any obligation to provide COBRA benefits or reimbursement pursuant to this paragraph shall cease immediately upon Employee’s securing new employment with substantially similar benefits. Except as described in this Agreement, Employee’s participation in all other benefits and incidents of employment ceased on the Termination Date.

(f) Tax Treatment. The Company will report to the Internal Revenue Service the payments described in this section as taxable income to the Employee.

3. Confidential Information. Employee shall continue to maintain the confidentiality of all confidential and proprietary information of the Company and shall continue to comply with the terms and conditions of the Confidentiality Agreement, which shall remain in full force and effect. Employee shall return all of the Company’s property and confidential and proprietary information in his possession to the Company on the Termination Date.

4. Final Check; Reimbursements. Employee acknowledges receipt of a check made payable to Employee, representing satisfaction in full of the Company’s payment obligation to Employee (subject to applicable withholding) for accrued salary, wages, bonuses or other compensation, including, without limitation, all amounts owing for accrued vacation or “paid time off” through the Termination Date and Employee’s earned bonus as of the Termination Date. Employee has submitted all receipts and other documentation for expenses incurred on behalf of the Company through the Termination Date that are reimbursable in accordance with the Company’s policies.

5. Release of Claims; Covenant Not to Sue. Employee agrees that the foregoing consideration represents settlement in full of all outstanding obligations owed to Employee by the Company and its officers, managers, supervisors, agents, and employees.

21. No Waiver. The failure of any party to insist upon the performance of any of the terms and conditions in this Agreement, or the failure to prosecute any breach of any of the terms and conditions of this Agreement, shall not be construed thereafter as a waiver of any such terms or conditions. This entire Agreement shall remain in full force and effect as if no such forbearance or failure of performance had occurred.
