                                   EXHIBIT 7.3

                               FINANCIAL COVENANTS

DEFINITIONS

            Consolidated EBITDA - for any period, the sum, without duplication,
of the amounts for such period of (i) Consolidated Net Income, (ii) Consolidated
Interest Expense, (iii) provisions for taxes based on income, (iv) total
depreciation expense, (v) total amortization expense, (vi) all unusual expenses
and all other non-capitalized restructuring expenses (including costs and
expenses attributable to employee severance obligations and facility
consolidation costs) for such period to the extent not disallowed by Agent in
its sole discretion, (vii) any payment of or accrual for the Management Fee
under the Management Agreement, (viii) all other payments made to K&C and its
Affiliates during such period for expenses incurred on behalf of Parent, Katy or
any of their respective Subsidiaries pursuant to Kohlberg Agreements, (ix) any
non-cash expense incurred with respect to Katy's stock appreciation rights plan
("SAR"); and (x) other non-cash items (other than any such non-cash item to the
extent that it represents an accrual of or reserve for cash expenditures in any
future period), but only, in the case of clauses (ii)-(ix), to the extent
deducted in the calculation of Consolidated Net Income less other non-cash items
added in the calculation of Consolidated Net Income (other than any such
non-cash item to the extent that it will result in the receipt of cash payments
in any future period), all of the foregoing as determined on a consolidated
basis for Katy and its Subsidiaries in conformity with GAAP; provided that there
shall be subtracted from the sum of items (i) through (xi) above the amount of
any cash expenditure made within the applicable period pursuant to the SAR, to
the extent that the amount of such cash expenditure was expensed or will be
expensed against a prior or future period's Consolidated Net Income; provided,
further, that (a) in the event any Loan Party makes an acquisition of any Person
or any division or any business unit permitted hereunder or consented to by
Majority Lenders during such period, if Katy provides Agent and Lenders
financial statements with respect to the business so acquired (which financial
statements shall have been audited by one of the "Big 4" accounting firms or
another nationally recognized accounting firm reasonably satisfactory to Agent
or financial statements otherwise satisfactory to Agent) reasonably satisfactory
to Majority Lenders, Consolidated EBITDA for such period shall be calculated on
a pro forma basis, taking into account the elimination of non-recurring
expenses, based on the results of such acquired Person or acquired assets as if
such acquisition had occurred on the first day of such period, and (b) in the
event any Loan Party makes a Permitted Disposition (or any other disposition of
any Person or any division or any business unit permitted hereunder or consented
to by the Majority Lenders) during such period, Consolidated EBITDA for such
period shall be calculated on a pro forma basis, based on the results of such
disposed Person or disposed assets as if such Permitted Disposition (or such
other disposition) had occurred on the first day of such period. The foregoing
notwithstanding, Consolidated EBITDA for: (i) the fiscal quarter ended June
30,2002 shall be deemed to equal $6,800,000; (ii) for the fiscal quarter ended
September 30,2002 shall be deemed to equal $12,000,000; and (iii) for the fiscal
quarter ended December 31, 2002 shall be deemed to equal $10,800,000.

<PAGE>

            Consolidated Interest Expense -for any period, total interest
expense of Katy and its Subsidiaries on a consolidated basis with respect to all
outstanding Indebtedness of Katy and its Subsidiaries, including, without
limitation, all commissions, discounts and other fees and charges owed with
respect to letters of credit and bankers' acceptance financing and net costs
under Interest Rate Agreements, but excluding, however, (i) any amounts referred
to in the Fee Letter.

            Consolidated Leverage Ratio, as at any date, the ratio of (a)
Consolidated Total Debt as at such date to (b) Consolidated EBITDA for the
consecutive four fiscal quarters ending on the last day of the most recently
ended fiscal quarter.

            Consolidated Net Income, for any period, the net income (or loss) of
Katy on a Consolidated basis for such period taken as a single accounting period
determined in conformity with GAAP; provided that there shall be excluded (i)
the income (or loss) of any Person (other than a Subsidiary of Katy) in which
any other Person (other than Katy or any of its Subsidiaries) has a joint
interest, except to the extent of the amount of dividends or other distributions
actually paid to Katy or any of its Subsidiaries by such Person during such
period, (ii) the income (or loss) of any Person accrued prior to the date it
becomes a Subsidiary of Katy or is merged into or consolidated with Katy or any
of its Subsidiaries or that Person's assets are acquired by Katy or any of its
Subsidiaries, (iii) the income of any Subsidiary of Katy to the extent that the
declaration or payment of dividends or similar distributions by that Subsidiary
of that income is not at the time permitted by operation of the terms of its
charter or any agreement, instrument, judgment, decree, order, statute, rule or
governmental regulation applicable to that Subsidiary, (iv) any after-tax gains
or losses attributable to Asset Sales or returned surplus assets of any Pension
Plan, (v) any LIFO reserves of Contico to the extent such LIFO reserves decrease
or increase net income of Contico, and (vii) (to the extent not included in
clauses (i) through (v) above) any net extraordinary gains or net extraordinary
losses.

            Consolidated Total Debt means, as at any date of determination, the
aggregate stated balance sheet amount (which shall not include the face amount
of undrawn Letters of Credit) of all Money Borrowed of Katy and its Subsidiaries
on the last day of the most recently ended fiscal quarter, determined on a
Consolidated basis in accordance with GAAP.
