     Re:  Voting of Katy Industries Common Stock

Gentlemen:

     It is our understanding that certain shareholders of Katy Industries, Inc.,
a Delaware corporation ("KATY"), including Wallace E. Carroll, Jr. ("CARROLL")
and CRL, Inc., a Delaware corporation ("CRL," and, together with Carroll and the
other shareholders, the "SHAREHOLDERS"), have entered into that certain Stock
Voting Agreement with KKTY Holding Company, L.L.C., a Delaware limited liability
company ("KKTY"), dated as of June 2, 2001 (the "EFFECTIVE DATE"), a fully
executed copy of which is attached hereto (the "STOCK VOTING AGREEMENT"),
pursuant to which the Shareholders have jointly and severally agreed to vote (or
cause to be voted) 2,480,000 shares of common stock, $1 par value, of Katy
("COMMON STOCK") owned (whether of record or beneficially) by the Shareholders
as of the Effective Date (the "SECURITIES") with respect to certain questions
that may be put to the Shareholders, in each case, in accordance with the terms
and conditions of the Stock Voting Agreement (the "VOTE").

     Also pursuant to the Stock Voting Agreement, each Shareholder has
severally, and not jointly:

          1)   appointed KKTY, and any designee of KKTY, each of them
individually, such Shareholder's proxy and attorney-in-fact, with full power of
substitution and resubstitution, to vote, to act by written consent or to
request that the chairman or secretary of Katy call a special meeting of the
stockholders, during the Closing Voting Period (as defined in the Stock Voting
Agreement) with respect to such Shareholder's Securities in accordance with the
Vote (the "PROXY");

          2)   represented and warranted that any proxies previously given in
respect of such Shareholder's Securities are not irrevocable, and that all such
proxies have been or are revoked (the "REVOCATION"); and

                              Page 27 of 32 Pages


          3)   covenanted not to request that Katy register the transfer
(book-entry or otherwise) of any certificate or uncertificated interest
representing any of such Shareholder's Securities during the Closing Voting
Period, unless such transfer is made in compliance with the Stock Voting
Agreement (the "STOP TRANSFER").

          Pursuant to that certain Pledge Agreement by and between CRL and The
Northern Trust Company, an Illinois banking corporation ("NORTHERN TRUST"),
dated as of December 31, 1995, as amended, restated, supplemented or otherwise
modified from time to time (the "CRL PLEDGE AGREEMENT"), CRL has pledged certain
shares of Common Stock to Northern Trust ("CRL PLEDGED SHARES") in order to
secure CRL's obligations under that certain Amended and Restated Revolving
Credit Agreement by and between CRL and Northern Trust, dated as of December 9,
1993, as amended, restated, supplemented or otherwise modified from time to time
(the "CREDIT AGREEMENT"). In addition, pursuant to that certain Pledge Agreement
by and between Carroll and Northern Trust dated as of February 28, 2001, as
amended, restated, supplemented or otherwise modified from time to time (the
"CARROLL PLEDGE AGREEMENT"), Carroll has pledged certain shares of Common Stock
to Northern Trust ("CARROLL PLEDGED SHARES"; together with the CRL Pledged
Shares, the "PLEDGED SHARES") in order to secure Carroll's obligations under
that certain Guaranty dated as of February 28, 2001 executed and delivered by
Carroll to and in favor of Northern Trust, as amended, restated, supplemented or
otherwise modified from time to time (the "GUARANTY").

          Northern Trust has examined the Stock Voting Agreement and,
notwithstanding any provisions to the contrary in the CRL Pledge Agreement, the
Credit Agreement, the Carroll Pledge Agreement, the Guaranty, or any other
agreement related thereto and delivered in connection therewith (collectively,
the "LOAN AGREEMENTS"), effective as of the Effective Date, hereby approves of
and authorizes: (i) the Vote and the Proxy, and hereby agrees to allow to be
voted, in such manner as Carroll, CRL or KKTY shall direct, in accordance with
the provisions of the Stock Voting Agreement, so many of the shares of Common
Stock as are subject to the Loan Agreements; (ii) the Revocation, provided the
Revocation operates only to revoke the proxy granted to Northern Trust with
respect to matters relating to the Vote; and (iii) so long as no event of
default or similar event shall have occurred under the Loan Agreements, the Stop
Transfer, and hereby agrees during the Closing Voting Period not to request, or
cause the Shareholders to request, Katy to register the transfer of any of the
shares of Common Stock as are subject to the Loan Agreements in the name of
Northern Trust or any other name, except as otherwise permitted by the Stock
Voting Agreement. Northern Trust further agrees to cooperate with Carroll, CRL
and the other Shareholders, at the expense of CRL and Carroll, in connection
with their respective efforts to fulfill any other agreements and covenants set
forth in the Stock Voting Agreement not inconsistent with the Loan Agreements
and this Letter.

          CRL and Carroll hereby represent and warrant that neither of them,
directly or indirectly, have received any consideration or remuneration in
exchange for entering into the Stock Voting Agreement. Except with respect to
the Vote and the Revocation only with respect to matters relating to the Vote,
this Letter and the consents herein shall terminate and be deemed withdrawn
automatically upon the expiration of the Closing Voting Period.

          Any failure to comply with the terms of the Agreement shall be deemed
to constitute an immediate event of default or default for purposes of the Loan
Agreements, without

                              Page 28 of 32 Pages


further action or notice by Northern Trust and Northern Trust may declare all
obligations under the Loan Agreements immediately due and payable.

          This Letter shall be binding upon the successors, assigns, heirs,
executors and other legal representatives of the parties hereto. This Letter
shall be governed by and construed in accordance with the internal laws of the
State of Illinois.


                                        Sincerely,

                                        THE NORTHERN TRUST COMPANY,
                                        an Illinois banking corporation
