Separation Date: You and the Company mutually agreed that your employment with the Company will end on March 31, 2017 (the “Separation Date”). Whether or not you sign this Agreement, you will receive the following: a. On the Separation Date, you will receive a final paycheck, plus an additional lump sum payment in the gross amount of $72,500, less applicable state and federal tax withholdings, which equals two months of your base salary; b. If you timely elect to continue your medical, dental and vision insurance benefits through COBRA pursuant to Section 2.b. below, the Company will pay the cost of two months of your and your eligible dependents’ COBRA premiums (“Special COBRA”), subject to Section 3 below; and c. Effective as of the Separation Date, the vesting of each of your then outstanding stock options and/or restricted stock units (“Equity Awards”) shall accelerate and become vested and exercisable as if you had remained employed with the Company and provided continuous service to the Company for two months following the Separation Date (the “Special Acceleration”). 2. Separation Compensation: In exchange for your agreement to the general release and waiver of claims set forth below and your other promises herein, the Company agrees to provide you with the following separation compensation (the “Separation Compensation”): x.

Xxxxxx Xxxx Page 2 Fitbit Confidential b. COBRA: Your medical, dental and vision insurance benefits will end on March 31, 2017. You will be eligible for COBRA starting April 1, 2017. Subject to Section 3 below, if you choose to timely elect COBRA, the Company will pay the full amount of your COBRA premiums on your behalf for your continued coverage under the Company’s health, dental and vision plans, including coverage for your eligible dependents, for an additional seven months (i.e., a total of nine months when considering the Special COBRA provided in Section 1.b. above). At the conclusion of this period, you shall be eligible to continue your coverage, pursuant to COBRA, and shall be responsible for the entire COBRA premium for the remainder of the applicable COBRA continuation period. Other Company benefits including life insurance, short term and/or long term disability insurance and workers’ compensation coverage will terminate on your Separation Date; and c. Partial Acceleration of Equity Awards; Exercise Deadline Extension: The Company agrees that, as of the Separation Date, in addition to the Special Acceleration, the vesting of your then outstanding Equity Awards shall accelerate and become vested and exercisable as if you had remained employed for seven months following the Special Acceleration period (i.e. a total of nine months from your Separation Date) (the “Secondary Acceleration”). Additionally, the Company agrees to provide you with a 12-month period from your Separation Date to exercise Company stock options that are vested and outstanding as of the Separation Date; provided that such post-termination exercise period shall end upon the consummation of a Change of Control (as defined in the Company’s 2007 Stock Plan (the “2007 Plan”)) or a Corporate Transaction (as defined in the Company’s 2015 Equity Incentive Plan (the “2015 Plan” and, together with the 2007 Plan, the “Plans” and each, a “Plan”)), unless such stock options are assumed in the Change of Control or the Corporate Transaction, as applicable; provided, further, that in no event shall such post-termination exercise period exceed the expiration of the maximum term of such stock options. You acknowledge that acceptance of this extension will cause the portion of the stock options that were incentive stock options to cease to be incentive stock options under the tax laws as of the Effective Date (as defined below) and, accordingly, at time of exercise you will be required to satisfy all applicable income and employment tax withholding requirements that become due upon exercise of the stock options. Except as otherwise specifically provided herein, any Company Equity Awards held by you, whether under the applicable Plan or otherwise, will remain subject to the terms and conditions of the applicable agreement(s) governing such Equity Awards and the applicable Plan (if any) (together, the “Equity Agreements”). Vesting of the Equity Awards will cease on the Separation Date (after taking into account the Special Acceleration and the Secondary Acceleration). You acknowledge that a report regarding the status of your Equity Awards as of the Separation Date was provided to you with this Agreement (the “Equity Report”). d. Umbrella Liability: The Company agrees to pay you, within fifteen (15) business days following the Effective Date of this Agreement, a total of $6,500 less applicable taxes and withholdings, to assist you with purchasing umbrella liability coverage. By signing below, you acknowledge that you are receiving the Separation Compensation outlined above in consideration for waiving your rights to claims referred to in this Agreement and that you would not otherwise be entitled to the Separation Compensation.

Notwithstanding anything to the contrary in Section 1(b) and/or Section 2(b), if the Company, in its sole discretion, determines that it cannot provide the subsidy of COBRA coverage without potentially violating or causing the Company to incur additional expense as a result of noncompliance with applicable law (including, without limitation, Section 2716 of the Public Health Service Act), the Company instead shall provide to you a taxable monthly payment in an amount equal to the monthly COBRA premium that you would be required to pay to continue the group health coverage in effect on the date of the Separation Date (which amount shall be based on the premium for the first month of COBRA coverage), which payments will be made regardless of whether you elect COBRA continuation coverage and will commence on the later of (i) the first day of the month following the Separation Date and (ii) the effective date of the Company’s determination of violation of applicable law, and will end on the earlier of (x) the effective date on which you become covered by a health, dental or vision insurance plan of a subsequent employer, and (y) the last day of the period two months after the Separation Date, in the case of Section 1(b), or nine months after the Separation Date, in the case of Section 2(b), provided that, any taxable payments under Section 2(b) will not be paid before the Effective Date, and, provided further that, once payments under this Section 3 commence (if at all), they will include any unpaid amounts accrued from the Separation Date (to the extent not otherwise satisfied with continuation coverage). However, if the 21 day period and the seven (7) day period described in Section 18 below plus, if applicable, the fifteen (15) day period described in Section 2(a) spans two calendar years, then the payments which constitute deferred compensation subject to Section 409A will not in any case be paid in the first calendar year. You have no right to an additional gross-up payment to account for the fact that such COBRA premium amounts are paid on an after-tax basis. 4. Return of Company Property: You hereby warrant to the Company that you have returned to the Company all property or data of the Company of any type whatsoever that has been in your possession or control. 5. Proprietary Information: You hereby acknowledge and agree that throughout your employment you were and you continue to be bound by the Company’s Employee Inventions and Proprietary Rights Assignment Agreement (the “Proprietary Rights Assignment Agreement”) and that as a result of your employment with the Company you have had access to the Company’s Proprietary Information (as defined in the Proprietary Rights Assignment Agreement), that you will hold all Proprietary Information in strictest confidence and that you will not make use of such Proprietary Information on behalf of anyone. You acknowledge that a copy of the applicable Proprietary Rights Assignment Agreement was provided to you with this Agreement. You further confirm that you have delivered to the Company all documents and data of any nature containing or pertaining to such Proprietary Information and that you have not taken with you any such documents or data or any reproduction thereof. 6. General Release and Waiver of Claims: To the fullest extent permitted by law, you hereby fully, forever, irrevocably and unconditionally release and discharge the Company, its current and former officers, directors, shareholders, corporate affiliates, subsidiaries, insurers, attorneys, parent companies, successors and assigns, agents, subscribers, and employees (each in their individual and corporate capacities) (collectively “Releasees”) from any and all claims, complaints, demands, causes of action, liabilities, and expenses (including attorneys’ fees and

Xxxxxx Xxxx Page 5 Fitbit Confidential “A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN HIS OR HER FAVOR AT THE TIME OF EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM OR HER MUST HAVE MATERIALLY AFFECTED HIS OR HER SETTLEMENT WITH THE DEBTOR.” 8. Acknowledgment of Wages Paid & Expenses Reimbursed: You acknowledge that you have been reimbursed by the Company for all business expenses incurred in conjunction with the performance of your employment and that no other reimbursements are owed to you.

You acknowledge that you will not receive any pay for time spent testifying as a witness or in other circumstances where applicable law may otherwise prohibit compensation. 12.
