May 25, 2012

Dear Patrick:

On behalf of Sonos Inc., I am delighted to offer you an exempt position as Chief Commercial Officer in our Santa Barbara, CA office. In your new position you will report to John MacFarlane. We look forward to welcoming you to Sonos.

Immigration

Sonos understands that you are presently not authorized for employment in the United States and that we will have to file necessary application forms to the US government to request that you be authorized for employment by Sonos. Pursuant to this understanding, we will, as an organization, file a petition to seek classification on your behalf. Sonos understands that it is obligated to pay any and all legal fees and government filing fees associated with this matter. As such, it is Sonos’s decision as to choose its own immigration counsel to represent it with respect to this matter. The final adjudication of this petition is to be made by the US Citizenship and Immigration Services. Sonos has no control over the adjudicative authority of the US government nor can we guarantee the petition will be approved. In the event that the petition is approved, you will then need to apply for a visa at a US Embassy or Consulate in your country of residence. Upon visa issuance, you may travel to the United States to be admitted pursuant to the visa. This offer of employment is contingent upon your presentation of documentation that demonstrates that you have the lawful right to employment for Sonos in the United States.

Remuneration

If you decide to join Sonos, you will receive an annual salary of $350,000, which will be paid semi-monthly in accordance with Sonos’ payroll procedures.

Bonus

You will be eligible to participate in the Sonos Bonus Plan. Employees can earn up to 15% of their base salary, according to the following funding parameters. There are two distinct components: (1) Individual Bonus: 10% of base salary will be available, and the annual bonus award is variable based on individual performance and impact; (2) Company Bonus: An additional 5% of base salary is available as an upside bonus opportunity measured by either a fiscal year Company target or, for some groups, a fiscal year goal measured by a specific organizational target. See your manager for details. Due to the shorter transition year for fiscal 2012, the Company bonus will be prorated at 75% for 9 months. If the employee starts between 1-February and 30-June, eligibility will be pro-rated for the applicable period. If the employee starts after 30-June, they will be ineligible for that year’s Bonus Plan. After this transition year in 2012, Sonos’ fiscal year will run from October 1-Sept. 30. The parameters of the Sonos Bonus Plan are subject to change on an annual basis.
