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)	The filing of this Form 4 shall not be construed as an admission that TCS Capital Investments, L.P. ("TCS Offshore"), TCS Capital GP, LLC ("TCS") or Eric Semler, the managing member of TCS, is or was for the purposes of Section 16(a) of the Securities Exchange act of 1934, as amended, or otherwise the beneficial owner of any of the common stock, par value $0.001 per share (the "Common Stock"), of Information Services Group, Inc. (the "Issuer") owned by TCS Capital, L.P., TCS Capital II, L.P., and TCS Offshore (collectively, the "Funds"). Pursuant to Rule 16a-1, the reporting persons disclaim such beneficial ownership beyond their pecuniary interest.
(2)	The Funds hold 3,979,300 of their shares of Common Stock in the form of units of the Issuer (the "Units"). Each Unit consists of one share of Common Stock and one redeemable common stock purchase warrant (the "Warrants"). The Funds also hold 615,000 shares of Common Stock directly.
(3)	TCS Offshore holds Common Stock and Units for its own account. TCS holds indirectly Common Stock and Units for the accounts of the Funds, of which TCS is the general partner. TCS receives an allocation of a portion of net profits from and owns a partnership interest in the Funds. Mr. Semler reports the shares held indirectly by TCS because, as the manager of TCS, at the time of sale, Mr. Semler controlled the disposition and voting of the securities.
(4)	This Form 4 is being filed to report the sale of Common Stock and Units by TCS Offshore to the other Funds. Therefore, after the transactions reported herein, the amount of securities beneficially owned in the aggregate by the Reporting Persons did not change. However, following the transactions reported herein, TCS Offshore holds 321,200 shares of Common Stock and 2,078,700 Units.
(5)	The Units were sold at a price of $4.01 per Unit.

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

Potential persons who are to respond to the collection of information contained in this form are not required to respond unless the form displays a currently valid OMB number.
