*	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)	Insight Enterprises, Inc. has withheld 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 preceeding trading date in the case that the vesting date is a non-trading date.
(2)	The restricted stock units were granted on February 14, 2007. The number of restricted stock units increased with the actual earnings per share (for the fiscal year ending December 31, 2007, on a consolidated non-GAAP diluted basis) and was greater than the target earnings per share. Vesting occurs in three equal installments beginning February 14, 2008.
