Exhibit 10.5

Non-Qualified Stock Option Agreement Amendment No. 1

This Non-Qualified Stock Option Agreement Amendment No. 1 (this “Amendment”) is made February 29, 2012 between Harris Interactive Inc., a Delaware corporation (the “Company”), and Al Angrisani (the “Participant”).

This Amendment amends the Non-Qualified Stock Option Agreement (the “Non-Qualified Stock Option Agreement”) made between the Company and the Participant effective as of June 7, 2011. All terms of the Non-Qualified Stock Option Agreement, except as amended hereby, remain in full force and effect. Capitalized terms not otherwise defined herein shall have the meanings given to them in the Non-Qualified Stock Option Agreement.

1. Section 1(b) of the Non-Qualified Stock Option Agreement is hereby deleted in its entirety.

2. Section 3(a) of the Non-Qualified Stock Option Agreement is hereby amended to read in its entirety as follows:

(a) The rights with respect to this Option shall vest and become exercisable with respect:

(i) 165,000 of the Covered Shares as of the date on which Target I (as defined below) is met;

(ii) 165,000 of the Covered Shares as of the date on which Target II (as defined below) is met;

(iii) 165,000 of the Covered Shares as of the date on which Target III (as defined below) is met;

(x) 165,000 of the Covered Shares as of the date on which Target X (as defined below) is met;

provided, however, in each case, to the extent that the Option has not vested on or before the Participant’s Date of Termination for any reason, such Option shall no longer vest and become exercisable in accordance with the foregoing schedule as of any date subsequent to the Participant’s Date of Termination except as provided in Section 3(b) with respect to a Change in Control (as defined in the Plan). Vesting under this schedule is cumulative, and after the Option becomes exercisable under the schedule with respect to any portion of the Covered Shares, it shall continue to be exercisable with respect to that portion, and only that portion, of the Covered Shares until the Expiration Date (described in Section 4 below), subject, however, to Section 4.15 of the Plan. For the avoidance of doubt, achievement of a higher target includes within it achievement of all lower targets to the extent not previously achieved.

(b) Notwithstanding the provisions of Section 3(a), the Option shall become fully vested and immediately exercisable with respect to all of the Covered Shares, whether or not previously vested, upon the occurrence of the date of a Change in Control under the condition that the date of the Change of Control does not occur prior to the Participant’s Date of Termination.
