(1) As of December 31, 2001, Omega had no outstanding borrowings outstanding
under the $20.0 million Credit Facility other than for $1.9 million in
standby letters of credit.
Because Zapata does not guarantee or otherwise assume any liability for
Omega Protein or Zap.Com or have any investment commitments to either Omega
Protein or Zap.Com, it is useful to separately review the cash obligations of
Zapata exclusive of Omega and Zap.Com ("Zapata Corporate"). The following table
summarizes information about Zapata Corporate's contractual cash obligations (in
thousands) as of December 31, 2001, and the effects such obligations are
expected to have on Zapata Corporate's liquidity and cash flow in future
periods:

Zapata's management believes that these liabilities have no material impact
on Zapata Corporate's liquidity and capital resources. As of the date of this
report, Zapata Corporate had no other commercial commitments which may impact
its capital resources and liquidity.
In the absence of unforeseen developments, Zapata believes that it has
sufficient liquidity to fund its operating expenses and other operational
requirements at least for the 12 months following the date of this report.
