THIS SECOND AMENDMENT TO AMENDED AND RESTATED CREDIT AGREEMENT (this
  "Amendment"), dated as of March 22, 2000, is entered into between KATY
  INDUSTRIES, INC., a Delaware corporation (the "Company"), the several
  financial institutions party to the Credit Agreement referred to below
  (the "Banks"), and Bank of America, N.A., as letter of credit issuing bank
  and as administrative agent for the Banks (the "Agent").

                                  RECITALS

        WHEREAS, the Company, the Banks, and the Agent are parties to the
  Amended and Restated Credit Agreement dated as of December 11, 1998, as
  amended by the First Amendment thereto dated as of November 18, 1999 (the
  "Credit Agreement"), pursuant to which the Banks have extended certain credit
  facilities to the Company; and

        WHEREAS, the Company has notified the Agent and the Banks that the
  Company will voluntarily reduce the Facility A Commitment and the
  Commercial L/C Commitment; and

        WHEREAS, the Company, the Banks, and the Agent now hereby wish to
  amend the Credit Agreement in certain respects, all as set forth in
  greater detail below;

        NOW, THEREFORE, for valuable consideration, the receipt and adequacy
  of which are hereby acknowledged, the parties hereto hereby agree as
  follows:

                1. Defined Terms.  Capitalized terms used herein and not
  otherwise defined shall have the meanings assigned to them in the Credit
  Agreement.

                2. Amendments to Credit Agreement.

                        (a) Amendment to Section 1.01.  The definition of
  "Commercial L/C Commitment" in Section 1.01 of the Credit Agreement is
  amended by deleting the amount "$30,000,000" and replacing it with the
  amount "$20,000,000."

                        (b) Amendment to Schedule 2.1.  Schedule 2.1 of the
  Credit Agreement is replaced with Schedule 2.1 to this Amendment.  The
  Borrower acknowledges and agrees that neither the Agent's nor the Banks'
  present agreement to permit a reduction of the Facility A Commitment by an
  amount other than that specified in Section 2.5 of the Credit Agreement
  shall be deemed to create a course of dealing or otherwise obligate the
  Agent or the Banks to permit a similar reduction under the same or similar
  circumstances in the future except as provided in Section 2.5 of the Credit
  Agreement.

                        (c) Amendment to Section 8.19.  Section 8.19 of the
  Credit Agreement is hereby amended to delete the ratios set forth therein
  and replace them with the following:

                Quarters Ending                 Maximum Leverage Ratio

        Through September 30, 1999                3.50 to 1.00

        December 31, 1999 through
        September 30, 2000                        3.25 to 1.00

        December 31, 2000 through
        Facility B Revolving Termination Date     3.00 to 1.00

                3. Representations and Warranties.  The Company hereby
  represents and warrants to the Agent and each of the Banks as follows:

                        (a) No Default or Event of Default has occurred and is
  continuing.

                        (b) The execution, delivery and performance by the
  Company of this Amendment have been duly authorized by all necessary
  corporate and other action and do not and will not require any registration
  with, consent or approval of, notice to or action by, any person
  (including any Governmental Authority) in order to be effective and
  enforceable.  The Credit Agreement as amended by this Amendment constitutes
  a legal, valid and binding obligation of the Company, enforceable against
  the Company in accordance with its respective terms, without defense,
  counterclaim or offset.

                        (c) All representations and warranties of the Company
  contained in the Credit Agreement are true and correct as though made on and
  as of the date hereof (except to the extent such representations and
  warranties specifically relate to an earlier date, in which case they were
  true and correct as of such earlier date).

                        (d) The Company is entering into this Amendment on
  the basis of its own investigation and for its own reasons, without reliance
  upon the Agent and the Banks or any other person.

                4. Effective Date.  This Amendment will become effective on
  the first Business Day that each of the following conditions precedent has
  been satisfied (the "Effective Date"):

                        (a) The Agent has received from the Company and the
  Required Banks a duly executed original or facsimile of this Amendment,
  together with a duly executed original or facsimile of a Guarantor
  Acknowledgment and Consent in the form attached hereto.

                        (b) The Agent has received from the Company payment,
  for the account of each Bank party to this Amendment, an upfront fee equal
  to 0.05% of such Bank's Commitments as calculated after giving effect to
  this Amendment.

                        (c) All representations and warranties contained
  herein are true and correct as of the Effective Date.

                5. Miscellaneous.

                        (a) Except as herein expressly amended, all terms,
  covenants and provisions of the Credit Agreement are and shall remain in
  full force and effect and all references therein and in the other Loan
  Documents to the Credit Agreement shall henceforth refer to the Credit
  Agreement as amended by this Amendment.  This Amendment shall be deemed
  incorporated into, and a part of, the Credit Agreement.

                        (b) This Amendment shall be binding upon and inure
  to the benefit of the parties hereto and thereto and their respective
  successors and assigns.  No third party beneficiaries are intended in
  connection with this Amendment.

                        (c) This Amendment shall be governed by and construed
  in accordance with the law of the State of California (without regard to
  principles of conflicts of laws).

                        (d) This Amendment may be executed in any number of
  counterparts, each of which shall be deemed an original, but all such
  counterparts together shall constitute but one and the same instrument.

                        (e) This Amendment, together with the Credit
  Agreement, contains the entire and exclusive agreement of the parties
  hereto with reference to the matters discussed herein and therein.
  This Amendment supersedes all prior drafts and communications with respect
  thereto.  This Amendment may not be amended except in accordance with the
  provisions of Section 11.1 of the Credit Agreement.

                        (f) If any term or provision of this Amendment shall
  be deemed prohibited by or invalid under any applicable law, such provision
  shall be invalidated without affecting the remaining provisions of this
  Amendment or the Credit Agreement, respectively.

                        (g) Company covenants to pay to or reimburse the
  Agent and the Banks, upon demand, for all costs and expenses (including
  Attorney Costs) incurred in connection with the development, preparation,
  negotiation, execution and delivery of this Amendment.

        IN WITNESS WHEREOF, the parties hereto have executed and delivered
  this Amendment as of the date first above written.

                (f) Section 2.16 of the Credit Agreement is hereby amended

           2.16  Extension of Facility A Revolving Termination Date.

           At any time and from time to time, at the request of the Company,
        any Bank or Banks holding Facility A Commitments may extend the
        Facility A Revolving Termination Date, effective on the Facility A
        Revolving Termination Date then in effect, to a date that is not more
        than 364 days following the Facility A Revolving Termination Date then
        in effect. In connection therewith, (1) each such Bank may decrease
        or, with the consent of the Company, increase its Facility A
        Commitment, and (2) upon the request of the Company, any Bank not
        then holding a Facility A Commitment or any Eligible Assignee
        desiring to become a Bank with a Facility A Commitment may provide
        the Company with a Facility A Commitment.  Each such extension shall
        be evidenced by a writing satisfactory to the Agent executed by each
        Bank participating in such extension or provision of the Facility A
        Commitments, the Company, and the Agent.  Notwithstanding the
        foregoing, in no event may the aggregate Facility A Commitments at
        any time exceed $23,837,209.31. If the Facility A Revolving
        Termination Date shall be so extended, all Facility A Loans shall
        be repaid in full with proceeds of new Facility A Loans or
        otherwise on the effective date of such extension.

                (g) Section 2.7 of the Credit Agreement ("Mandatory Prepayments
  of Loans; Mandatory Commitment Reductions") shall be amended by adding
  the following at the end thereof:

                Within 5 days after receipt by the Company or any Restricted
        Subsidiary of any Net Proceeds attributable to any sale or
        disposition (or series of related sales or dispositions) of assets
        having a book value of $1,000,000 or more, the Company shall prepay
        Facility B Loans in the amount of such Net Proceeds and the aggregate

        value of all assets so sold in any single transaction or series of

        June 30, 2000 financial statements, and (4) prior to becoming

        through (3) above and pro forma consolidated financial statements
        accompanied by a Compliance Certificate signed by a Responsible
        Officer certifying that at the end of the last fiscal quarter for
        which such financial statements and Compliance Certificate have
        been delivered pursuant to Sections 7.1 and 7.2, after giving pro
        forma effect for four trailing quarters to such disposition by
        excluding EBITDA with respect to the assets so sold, the Company
        and its Restricted Subsidiaries would have been in compliance with
        the financial covenants set forth in Sections 8.18, 8.19, 8.20 and
        8.21 (giving effect to the Third Amendment to this Agreement).

        the Perfection Date has occurred, in which case, at the Company's
        election, such Indebtedness may be secured on a pari passu basis
        with the Obligations as long as the holders of such Indebtedness have
        entered into intercreditor agreements reasonably satisfactory to the
        Agent and the Required Banks.

                (o) Section 9.1 ("Events of Default") is hereby amended by

  achieve the Perfection Date.

           4. Amendments Relating to Security. The Company agrees for the
  benefit of each of the parties hereto that no amendment or waiver of the
  Credit Agreement shall be effective if such waiver or amendment amends
  the definitions of "Event Obviating Security" or "Perfection Date",
  Section 7.15, or subsection 9.1(q), in each case as set forth herein,
  or waives compliance by the Company with Section 7.15 or subsection
  9.1(q), unless such amendment or waiver is executed or consented to
  by each of the Banks signatory to this Waiver and Amendment on the
  Effective Date.

           5. Representations and Warranties. The Company hereby
  represents and warrants as follows:

                (a) After giving effect to this Waiver and Amendment,
  no Default or Event of Default exists.

                (b) The execution, delivery and performance by the Company
  of this Waiver and Amendment have been duly authorized by all necessary
  corporate and other action and does not and will not require any
  registration with, consent or approval of, notice to or action by, any
  person (including any governmental agency) in order to be effective and
  enforceable.  The Credit Agreement as amended by this Waiver and
  Amendment constitutes the legal, valid and binding obligations of the
  Company, enforceable against it in accordance with its respective terms,
  without defense, counterclaim or offset.

                (c) After giving effect to this Waiver and Amendment, all
  representations and warranties of the Company contained in the Credit
  Agreement are true and correct.

                (d) The Company is entering into this Waiver and Amendment
  on the basis of its own investigation and for its own reasons, without
  reliance upon the Agent, the Banks or any other person.

           6. Effective Date.  This Waiver and Amendment will become effective
  on the first Business Day that each of the following conditions precedent
  has been satisfied (the "Effective Date"):

                (a) The Agent has received from the Company and the Required
  Banks a duly executed original or facsimile of this Waiver and Amendment,
  together with a duly executed Guarantor Acknowledgment and Consent in the
  form attached hereto ("Consent").

  providing facsimile of its signature page to the Agent on or before 3:00
  p.m. (San Francisco time) on October 25, 2000, shall have received from
  the Company an amount equal to .25% of such Bank's respective Facility
  B Commitment, representing payment in full of a nonrefundable amendment
  fee, which fee shall have been paid to the Agent by the Company for the
  account of each such Bank.

           7. Reservation of Rights.  The Company acknowledges and agrees
  that neither the execution and delivery by the Agent and the Banks of
  this Waiver and Amendment shall be deemed (i) to create a course of
  dealing or otherwise obligate the Agent or the Banks to forbear or
  execute similar waivers under the same or similar circumstances in the
  future, or (ii) to waive, relinquish or impair any right of the Agent
  or the Banks to receive any indemnity or similar payment from any person
  or entity as a result of any matter arising from or relating to the
  defaults waived hereunder.

           8. Miscellaneous.

                (a) Except as herein expressly amended, all terms,
  covenants and provisions of the Credit Agreement are and shall remain

  incorporated into, and a part of, the Credit Agreement.

                (b) This Waiver and Amendment shall be binding upon and
  inure to the benefit of the parties hereto and thereto and their
  respective successors and assigns.  No third party beneficiaries are
  intended in connection with this Waiver and Amendment.

  (without regard to principles of conflicts of laws).

                (d) This Waiver and Amendment may be executed in any
  number of counterparts, each of which shall be deemed an original,
  but all such counterparts together shall constitute but one and the
  same instrument.

                (e) This Waiver and Amendment, together with the
  Credit Agreement, contains the entire and exclusive agreement of the
  parties hereto with reference to the matters discussed herein and
  therein. This Waiver and Amendment supersedes all prior drafts and
  communications with respect thereto.  This Waiver and Amendment may
  not be amended except in accordance with the provisions of
  Section 11.1 of the Credit Agreement.

                (f) If any term or provision of this Waiver and
  Amendment shall be deemed prohibited by or invalid under any
  applicable law, such provision shall be invalidated without
  affecting the remaining provisions of this Waiver and Amendment or
  the Credit Agreement, respectively.

                (g) Company covenants to pay to or reimburse the Agent,
  upon demand, for all costs and expenses (including allocated costs of
  in-house counsel) incurred in connection with the development,
  preparation, negotiation, execution and delivery of this Waiver and
  Amendment and the administration of the existing defaults, including
  without limitation appraisal, audit, search and filing fees incurred in
