Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) Upon the vesting of Restricted Stock Units, Insight Enterprises, Inc. withholds the number of whole shares necessary to satisfy the minimum statutory tax withholding obligations. The value of the vested shares (and the taxable income) is calculated based on the closing price on the vesting date or next preceding trading date in the case that the vesting date is a non-trading date. The shares reported on this Form 4 were acquired in an adjustment to the number of shares withheld (due to the incorrect application of the withholding rate following changes to tax rates in early 2013) on vesting of Restricted Stock Units on 2-20-13 to satisfy the minimum statutory tax withholding obligations with respect to Restricted Stock Units granted on 2-20-10, 2-20-11 and 2-20-12, and in an adjustment to the number of shares withheld on vesting of Restricted Stock Units on 4-10-13 to satisfy the minimum statutory tax withholding obligations with respect to Restricted Stock Units granted on 4-10-12.

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.
