        <footnote id="F1">Each Unit consist of one share of Common Stock, par value $0.001 per share (&quot;Common Stock&quot;), and one redeemable common stock purchase warrant.</footnote>
        <footnote id="F2">The filing of this Form 3 shall not be construed as an admission that 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, of Information Services Group, Inc. owned by TCS Capital, L.P., TCS Capital II, L.P., and TCS Capital Investments, L.P (collectively, the &quot;Funds&quot;).  Pursuant to Rule 16a-1, both TCS and Mr. Semler disclaim such beneficial ownership beyond their pecuniary interest.</footnote>
        <footnote id="F3">TCS holds indirecly Common Stock 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 purchase, Mr. Semler controlled the disposition and voting of the securities.</footnote>
    </footnotes>

    <remarks>The Reporting Persons did not cross the 10% beneficial ownership threshold as a result of a transaction in the Issuer's common stock;
rather, the Reporting Persons crossed the 10% threshold as a result of the Issuer's reduction in the total number of outstanding shares
of common stock.  The Reporting Persons filed this Form 3 promptly after becoming aware of the Issuer's outstanding share reduction.</remarks>
