Dear Jean-Baptiste:

On behalf of Criteo Corp., (Criteo or the Company), I am pleased to offer you the position
of Chief Executive Officer. The terms of your position with the Company, should you accept this offer, will be as set forth below:

Position and
Salary. You will generally work out of the Companys offices in Palo Alto, but will be expected to travel as required. As a Company employee, you will (i) carry out your duties, as directed by the Company, in a diligent, competent,
faithful and professional manner; (ii) work with other employees of the Company in a competent and professional manner; and (iii) generally promote the interests of the Company. Your starting annual, base salary will be $270,000
(your Salary) less applicable taxes, deductions and withholding. Your Salary will be payable in accordance with the Companys standard payroll practices and subject to annual review. The Companys business is
fast-growing and changes quickly. As such, the Company may change your title and duties from time to time to suit its business needs, or change your Salary as it deems appropriate. In addition, the Company may transfer you to another location within
the United States.

Bonus. You will also be eligible for a standard discretionary annual management plan bonus of 100 % of your base
salary (Target Bonus), pro-rated based on the period of time you are employed at Criteo during the relevant year, less applicable taxes, deductions and withholdings. Target incentives do not constitute a promise of payment. Your
actual bonus payout will depend on the Companys financial performance and managements assessment of your group or individual performance. Your bonus is capped at a maximum of 125% of the Target Bonus. The Board of Directors will
determine in its sole discretion at the appropriate times whether the Company has achieved its targeted financial performance. Your bonus will be paid on an annual basis upon calculation of your actual achievement, as determined by the Company
in its sole discretion. At any time, the Company may change, at its sole discretion, the way this bonus is structured, calculated and paid. In that case, the Company will ensure that you remain eligible for your Target Bonus in the case you
achieve 100% of the targets given to you. The Board of Directors will review your Target Bonus periodically, and in its sole discretion, consider any increases/adjustments (including as to structure) it deems appropriate at that time. In order to be
eligible for any bonus, you must be an active employee at, and not have given or received notice of termination of your employment prior to, the time of the payment of such bonus. Please note that payment of a bonus in any year or years does not in
any way guarantee payment of a bonus in any other year or years.

Medical and Other Benefits. A significant part of your total compensation
at Criteo is derived from the benefits that Criteo provides. As a Company employee, you will be eligible to participate in the Companys benefits, effective the first date of the month following your Employment Date. In order to be eligible to
participate in the Companys benefits, you will need to complete your online enrollment within 30 days from your Employment Date. Criteo may change or terminate such benefit plans or programs at any time in its sole discretion and subject to
the eligibility requirements and rules of each such plan or program. You will be eligible to accrue up to twenty (20) days of paid time per full year of employment with the Company. You can accrue up to 1.5 times your applicable accrual rate
(the Accrual Cap). Once you reach the Accrual Cap, you will cease accruing paid time off until you use days and take your available balance below the Accrual Cap.
