Dear Erik:

On behalf of Logitech Inc. (“Logitech”), and subject to the ratification of the Compensation Committee of the Board of Directors of Logitech International S.A.

In such position, you will have the duties and authority at a level consistent with the duties and authority set forth on Exhibit A.

Your bi-weekly base salary will be $15,384.61, payable every two weeks (annualized this amount is $400,000). You will also be eligible to participate in Logitech International’s Management Performance Bonus Plan, targeted at 65% of your base salary for a potential annual total compensation of $660,000.

We will recommend that the Compensation Committee of Logitech International’s Board of Directors approve a grant to you of 100,000 stock options on Logitech International shares. These options will vest over a 4-year period, with 25% vesting on your start date anniversary each year. The receipt of any grant shall be conditioned upon the subsequent execution by you of a Logitech stock option grant agreement. Any future grant of employee equity incentives to you will be reviewed pursuant to the same general process employed for all executives of comparable status.

Logitech offers medical, dental and vision plans (effective on your date of hire), company-paid life insurance, voluntary life insurance, a Section 125 flexible spending plan, a 401(k) retirement savings plan, short term disability, long-term disability, share purchase plan, as well as 20 days per year of combined accrued vacation and sick leave and 11 paid holidays. For additional information on Logitech’s comprehensive benefits programs, please log on to our benefits website using instructions that will be provided to you.

In addition, we will recommend that the Compensation Committee of Logitech International’s Board of Directors approve the entry into with you of a Change of Control Severance Agreement, in the form substantially as entered into with other Logitech non-CEO executive officers.
