        <footnote id="F2">$24.13 was the last sale price for LWAY common stock on The Nasdaq National Market on April 12, 2004.</footnote>
        <footnote id="F3">Of the 1,506,323 total shares indicated as beneficially owned, 112,098 shares are owned directly by Edward and 1,394,225 shares are indirectly beneficially owned as a result of his indirect pecuniary interest in LWAY shares held in the Estate of Michael Smolyansky, Edward's father and the founder and former President and CEO of LWAY.  On 3/5/2003, pursuant to the Illinois Probate Act and the Internal Revenue Code, Edward filed a disclaimer (the &quot;Disclaimer&quot;) wherein he disclaimed his interest in the LWAY shares held by the Estate.  The Disclaimer was filed in the Cook County, Illinois Circuit Court on 3/10/2003.  As a result, Edward has no pecuniary interest in the Estate's LWAY shares.  Further, he disclaims the indirect pecuniary interest in the Estate's LWAY shares attributable to him under Section 16 of the Securities Exchange Act of 1934.</footnote>
