        <footnote id="F1">The filing of this Form 4 shall not be construed as an admission that TCS Capital Investments, L.P. (&quot;TCS Offshore&quot;),  TCS Capital GP, LLC (&quot;TCS&quot;) 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 &quot;Common Stock&quot;), or any of the redeemable common stock purchase warrants (the &quot;Warrants&quot;) of Information Services Group, Inc. (the &quot;Issuer&quot;) owned by TCS Capital, L.P., TCS Capital II, L.P., and TCS Offshore (collectively, the &quot;Funds&quot;).  Pursuant to Rule 16a-1, the reporting persons disclaim such beneficial ownership beyond their pecuniary interest.</footnote>
        <footnote id="F2">TCS Offshore holds Common Stock and Warrants for its own account. TCS holds indirectly Common Stock and Warrants 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.</footnote>
        <footnote id="F3">This Form 4 is being filed to report the rebalancing sale of Common Stock and Warrants by TCS Offshore Fund 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, the amount of securities held by TCS Offshore following the transactions reported herein did change so that as of the date of this filing TCS Offshore holds 1,967,700 shares of Common Stock and 1,834,400 Warrants.</footnote>
