 Appendix A - 2012 Performance Option (Mayer Retention Grant) 

Vesting of Option 
 Subject to Sections 6 and 7 of
the Original Agreement, the Annual Tranche for the Performance Year shall be eligible to vest in accordance with this Appendix A. 
  

			
	 Performance Year
	  	Vesting Date
	 2016
	  	January 26, 2017

  

	 	•	 	For the Performance Year, the “Performance Metrics” and “Weightings” shall be as follows: GAAP Revenue (one-third), Revenue ex-TAC (one-third), and Adjusted EBITDA (one-third). 


 

	 	•	 	For each Performance Metric, the Administrator has established a performance target (“Goal”) for the Performance Year. The Goals will be communicated to the Optionee. 


 

	 	•	 	After the end of 2016, the Company’s actual results for each Performance Metric shall be adjusted for purposes of this Option as set forth in “Definitions and Adjustments,” below. 


 

	 	•	 	For each Performance Metric, a vesting percentage (each, a “Component Vesting Percentage”) shall be calculated based on the Company’s actual performance (as adjusted) for the Performance Year as follows
(with actual performance expressed as a percentage of the applicable Goal): 

  

			
	 GAAP Revenue

Actual Performance (as adjusted) relative to Goal
	  	Component Vesting
Percentage
	 80% or less
	  	0%
	 100%
	  	100%
	 106% or more
	  	130%
		
	 Revenue Ex-TAC

Actual Performance (as adjusted) relative to Goal
	  	Component Vesting
Percentage
	 80% or less
	  	0%
	 100%

	  	130%

  

	 	•	 	If the Company’s actual performance (as adjusted), as to a particular Performance Metric, is between two levels specified in the applicable table above, the Component Vesting Percentage for such metric shall be
determined by linear interpolation between the vesting percentages specified for those two levels in such table (without rounding the result). In no event shall any Component Vesting Percentage exceed 130 percent. 


  
 A-1 









	 	•	 	For each Performance Metric, a weighted vesting percentage (each, a “Weighted Vesting Percentage”) shall be calculated by multiplying such metric’s Component Vesting Percentage by such metric’s
Weighting. 

  

	 	•	 	The overall vesting percentage applicable to the 2016 Annual Tranche (the “Overall Vesting Percentage”) shall equal the sum of the three Weighted Vesting Percentages, with such sum rounded to the nearest one
percent; provided, however, that the Overall Vesting Percentage shall not exceed 100 percent. 

  

	 	•	 	For the 2016 Annual Tranche, the number of options that vest shall be determined by applying the Overall Vesting Percentage to the number of shares underlying the 2016 Annual Tranche, and rounding down to the nearest
whole share. 

  

	 	•	 	Regardless of the vesting dates shown above, the vested portion of the Annual Tranche shall become exercisable on the date of the Administrator’s vesting determination described below. 


The Administrator shall, following the end of the 2016 Performance Year, determine whether and the extent to which the applicable Goals have been satisfied
and the vesting percentage of the 2016 Annual Tranche. Such determinations by the Administrator shall be final and binding. Any portion of the 2016 Annual Tranche that is not vested after giving effect to the Administrator’s determination for
the Performance Year shall terminate as of the final day of such Performance Year. 
 Maximum Vesting. Notwithstanding any other provision
herein, in no event shall the 2016 Annual Tranche vest as to more than one hundred percent (100%) of the options subject to such Annual Tranche.
