          (50%) of the net income, if any, of Borrowers on a consolidated basis
          for such fiscal year then ended, calculated in accordance with GAAP,
          and provided further, however, that, notwithstanding the foregoing,
          such Net Worth as of December 31, 2001 shall be in an amount not less
          than $16,500,000, and
