        <footnote id="F1">The Series B preferred shares are convertible into common stock after three years (or immediately upon a change in control)
 on a one-to-one basis.</footnote>
        <footnote id="F2">Sun Pharma Global, Inc. (&quot;Sun Global&quot;) earns 544,000 shares of Series B Preferred Stock for each technology transfer to
Caraco of a generic drug by Sun Global when such drug passes its bioequivalency studies. In the event of the dissolution of
Caraco, such shares have a preference equal to the value attributed to them on the dates on which they were earned. The value
attributed as of July 28, 2006 was $6.95 per share. In a previous Form 4, with respect to preferred shares earned as of
July 10, 2006, the value incorrectly attributed to them was $8.82 per share; the correct value is $6.62 per share.</footnote>
        <footnote id="F3">The shares of Series B Preferred Stock remain outstanding until such time as they are converted into Common Stock.</footnote>
        <footnote id="F4">These shares are owned directly by Sun Global, Inc., which is a wholly-owned subsidiary of Sun Pharmaceutical Industries
Limited (&quot;Sun&quot;). Dilip S. Shanghvi is the controlling shareholder of Sun.</footnote>
