                                  SCHEDULE 13D

ITEM 1.             SECURITY AND ISSUER.

          This Statement on Schedule 13D (this "Statement") relates to the
common stock, $0.01 par value per share (the "Company Common Stock") of ITI
Technologies, Inc., a Delaware corporation (the "Company"). The principal
executive offices of the Company are located at 2266 North Second Street, North
St. Paul, Minnesota, 55109.

ITEM 2.             IDENTITY AND BACKGROUND.

          This Statement is being filed jointly pursuant to Rule 13d-1(k)(1)
promulgated under the Securities Act of 1934, as amended (the "Exchange Act"),
by SLC Technologies, Inc., a Delaware corporation ("SLC") and Berwind Group
Partners, a Pennsylvania general partnership ("Berwind"). Hereinafter each of
SLC and Berwind is referred to individually as a "Reporting Person" and
collectively as the "Reporting Persons." The agreement among the Reporting
Persons relating to the joint filing of this Statement is attached as Exhibit 1
hereto.

          SLC is principally engaged in the business of providing global
integrated communications technology for security and life safety systems. The
address of the principal business and executive offices of SLC is 12345 SW
Leveton Drive, Tualatin, Oregon 97062. Berwind is the sole stockholder of SLC.
Berwind is a private partnership principally engaged, through its subsidiaries,
in the ownership and operation of industrial, natural resources, financial and
real estate businesses. The address of the principal business and executive
offices of Berwind is 1 Belmont Avenue, Suite 401, Bala Cynwyd, PA 19004.
Berwind is a general partnership owned by five trusts, each of which was
organized in Pennsylvania (collectively, the "Berwind Trusts"). The name and
address of the business and principal office of each of the Berwind Trusts is
set forth in Schedule A hereto. The principal business of each Berwind Trust is
to hold investments for the benefit of its beneficiaries.

          The name, business address, present principal occupation or
employment, and the name, principal business and address of any corporation or
other organization in which such employment is conducted, and citizenship of
each director and executive officer of SLC are set forth in Schedule A hereto.
The name, business address, present principal occupation or employment, and the
name, principal business and address of any corporation or other organization in
which such employment is conducted, and citizenship of each authorized
representative of Berwind and of each trustee of the Berwind Trusts are set
forth in Schedule A hereto.

          During the last five years, neither SLC nor Berwind, nor, to the best
knowledge of SLC and Berwind, any of the persons referred to in this Item 2, (i)
has been convicted in a criminal proceeding (excluding traffic violations or
similar misdemeanors) or (ii) was a party to a civil proceeding of a judicial or
administrative body of competent jurisdiction as a result of which any such
person was or is subject to a judgment, decree or final order enjoining future
violations of, or prohibiting or mandating activities subject to, federal or
state securities laws or finding any violation with respect to such laws.

ITEM 3.             SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

          The source of funds that will be used in connection with the Merger
described in Item 4 is expected to be borrowings from a syndicate of banks. SLC
has received a financing commitment for $325,000,000 in connection with the
Merger from The Bank of Nova Scotia, PNC Bank, National Association and PNC
Capital Markets, Inc., which commitment is subject to customary conditions. A
copy of this commitment letter is included as Exhibit 10 to this Statement and
is incorporated by

                                      -3-
<PAGE>

reference herein.

ITEM 4.             PURPOSE OF TRANSACTION.

          SLC and the Company have entered into the Agreement and Plan of Merger
and Reorganization dated as of September 28, 1999 (the "Merger Agreement"),
pursuant to which, among other matters and subject to the terms and conditions
set forth in the Merger Agreement, SLC will merge with and into the Company,
with the Company as the surviving corporation (the "Merger"). In the Merger,
SLC's outstanding common stock will be converted into 15,170,640 shares of
Company Common Stock. The Company's stockholders may elect to receive $36.50 in
cash at the effective time of the Merger for each share of Company Common Stock
owned, subject to the limitation that no more than 50 percent of the total
number of shares of Company Common Stock outstanding immediately prior to the
effective time of the Merger will be exchanged for cash. If the Company's
stockholders elect to exchange more than 50 percent of the outstanding shares of
Company Common Stock for cash, then the shares to be exchanged will be reduced
on a pro rata basis so that 50 percent of the outstanding shares of Company
Common Stock immediately prior to the effective time of the Merger are exchanged
for cash. As a result of the transaction, Berwind will have a 63.5 percent
ownership interest in the Company (on an equivalent shares basis calculated
under the treasury stock method), without giving effect to the cash election, or
a 78 percent ownership stake after giving effect to the cash election and
assuming that 50 percent of the outstanding shares of Company Common Stock are
exchanged for cash.

          The Merger will be treated as a purchase by SLC for accounting
purposes. The Merger is intended to constitute a tax-free reorganization  under
the Internal Revenue Code of 1986, as amended, except for shares exchanged for
cash.

          Consummation of the Merger is subject to various conditions, including
(i) receipt of approval by the stockholders of the Company; (ii) receipt by SLC
of a supplemental ruling from the Internal Revenue Service on certain matters;
(iii) the expiration or termination of applicable waiting periods under the
Hart-Scott-Rodino Antitrust Improvements Act; and (iv) satisfaction of certain
other conditions.

          In connection with, and as a condition to entering into, the Merger
Agreement, SLC required certain stockholders of the Company to enter into Voting
Support Agreements described more completely in Item 6, by which they have
agreed, among other things, to vote their stock in favor of the Merger and have
granted irrevocable proxies to SLC for that purpose.

          On September 28, 1999, prior to the execution of the Merger Agreement,
the Company and Norwest Bank, Minnesota, National Association entered into
Amendment No. 1 to the Rights Agreement dated as of November 27, 1996. A copy of
Amendment No. 1 to Rights Plan is included as Exhibit 8 to this Statement and is
incorporated by reference herein. The foregoing description of Amendment No. 1
to the Rights Plan is qualified in its entirety by reference to the full text of
Amendment No. 1 to the Rights Plan.

          Pursuant to the terms of the Merger, at the effective time of the
Merger, the total number of persons serving on the Board of Directors of the
Company shall be nine (unless otherwise agreed in writing by the parties hereto
prior to the effective time of the Merger), two of whom shall be Thomas L. Auth
and Perry J. Lewis and seven of whom shall be selected by and at the absolute
discretion of the Board of Directors of SLC. Thereafter, membership on the Board
of Directors of the Company shall be determined in accordance with a voting
agreement by and among Berwind, Thomas L. Auth and MLGA Fund II, L.P. to be
executed at the effective time of the Merger (the "Voting Agreement"), the form
of which is included as Exhibit 9 to this Statement and incorporated by
reference herein. The foregoing

                                      -4-
<PAGE>

description of the Voting Agreement is qualified in its entirety by reference to
the full text of the form of the Voting Agreement. Pursuant to the Voting
Agreement, Berwind will agree, subject to the terms of the Voting Agreement,
that until the second anniversary of the effective time of the Merger, it will
vote all shares of Company Common Stock owned by it for the following
individuals as directors of the Company: (a) Thomas L. Auth, who will serve as
Chairman of the Board of Directors of the Company, and (b) Perry J. Lewis, but
only for so long as he and certain controlled affiliates collectively own
(beneficially and of record) at least 25% of the shares of Company Common Stock
collectively owned by him and such controlled affiliates immediately prior to
the effective time of the Merger.

          Pursuant to the terms of the Merger, at the effective time of the
Merger, the Certificate of Incorporation of the Company shall be amended to opt
out of Section 203 of the Delaware General Corporation Law and to increase the
number of authorized shares of Company Common Stock to 60,000,000.

          A copy of the Merger Agreement is included as Exhibit 2 to this
Statement and is incorporated by reference herein. The foregoing description of
the Merger Agreement is qualified in its entirety by reference to the full text
of the Merger Agreement.

          Other than as described above or in Item 6 or 7 below, none of the
Reporting Persons has any plans or proposals that relate to or would result in
(i) the acquisition by any person of additional securities of the Company, or
the disposition of securities of the Company, (ii) an extraordinary corporate
transaction, such as a merger, reorganization or liquidation, involving the
Company or any of it is subsidiaries, (ii) a sale or transfer of a material
amount of assets of the Company or of any of its subsidiaries, (iv) any change
in the present board of directors or management of the Company, including any
plans or proposals to change the number or term of directors or to fill any
existing vacancies on the board, (v) any material change in the present
capitalization or dividend policy of the Company, (vi) any other material change
in the Company's business or corporate structure, (vii) changes in the Company's
charter, bylaws or instruments corresponding thereto or other actions which may
impede the acquisition of control of the Company by any person, (viii) causing a
class of securities of the Company to be delisted from a national securities
exchange or to cease to be authorized to be quoted in an inter-dealer quotation
system of a registered national securities association, (ix) a class of equity
securities of the Company becoming eligible for termination of registration
pursuant to Section 12(g)(4) of the Exchange Act or (x) any action similar to
those enumerated above, although subject to the provisions of the Merger
Agreement, they reserve the right to develop such plans.

ITEM 5.             INTEREST IN SECURITIES OF THE ISSUER.

          Under the definition of "beneficial ownership" as set forth in Rule
13d-3 under the Exchange Act, SLC may be deemed to beneficially own 1,607,737
shares of Company Common Stock or approximately 19.1% of the outstanding Company
Common Stock (based upon 8,438,342 shares of Company Common Stock outstanding as
represented by the Company in the Merger Agreement), subject to the Voting
Support Agreements. As a result of their relationship with SLC, each of the
executive officers and directors of SLC listed on Schedule A may be deemed to
have indirect beneficial ownership of the Company Common Stock with respect to
which SLC has beneficial ownership; however, each such individual disclaims
beneficial ownership of the Company Common Stock. Berwind is the sole owner of
SLC and the general partners of Berwind are the Berwind Trusts. Accordingly,
Berwind, Berwind's authorized representatives, the Berwind Trusts and the
trustees of the Berwind Trusts may be deemed to have indirect beneficial
ownership of any Company Common Stock deemed to be beneficially owned by SLC;
however, each such authorized representative, Berwind Trust and trustee
disclaims beneficial ownership of the Company Common Stock. Neither the filing
of this Statement nor any of its contents shall be deemed to constitute an
admission that any of the foregoing persons is the beneficial

                                      -5-
<PAGE>

owner of the Company Common Stock referred to in this Item for purposes of
Section 13(d) of the Exchange Act or any other purpose.

          Except as disclosed in this Statement, to the best of the Reporting
Persons' knowledge, none of the persons named in Item 2 hereof or on Schedule A
hereto beneficially owns any shares of Company Common Stock, nor have any
transactions in Company Common Stock been effected during the past 60 days by
any Reporting Person or, to the best knowledge of the Reporting Person, by any
of the persons named in Item 2 hereof or on Schedule A hereto. In addition, no
other person is known by the Reporting Persons to have the right to receive or
the power to direct the receipt of dividends from, or the proceeds from the sale
of, the securities covered by this Statement.


ITEM 6.             CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS
                    WITH RESPECT TO SECURITIES OF THE ISSUER.

          On September 28, 1999, SLC entered into an agreement with the
following stockholders of the Company: Thomas L. Auth, Auth Family Limited
Partnership, Sangwoo Ahn, Perry J. Lewis and MLGA Fund II, L.P. (each such
agreement, a "Voting Support Agreement" and such agreements collectively, the
"Voting Support Agreements"). Pursuant to the Voting Support Agreements, each
such stockholder has agreed, among other things, to vote or cause to be voted
all of the shares of Company Common Stock owned by such stockholder (i) in favor
of the Merger, (ii) against any action or agreement that would result in a
breach in any material respect of any covenant, representation or warranty or
any other obligation or agreement of the Company under the Merger Agreement, and
(iii) against any action or agreement that would impede, interfere with, delay,
postpone or attempt to discourage the Merger. Each of the stockholders that
entered into a Voting Support Agreement granted SLC an irrevocable proxy to vote
his or its shares of Company Common Stock as indicated in the immediately
preceding sentence. The stockholders who executed Voting Support Agreements are
estimated to have voting power over approximately 19.1% of the outstanding
shares of Company Common Stock, based upon 8,438,342 shares of Company Common
Stock outstanding as represented by the Company in the Merger Agreement. Copies
of the Voting Support Agreements are filed as Exhibits 3, 4, 5, 6, and 7 to this
Statement and are incorporated by reference herein. The foregoing description of
the Voting Support Agreements is qualified in its entirety by reference to the
full text of the Voting Support Agreements.

          A copy of the Merger Agreement is filed as Exhibit 2 to this Statement
and is incorporated by reference herein. The foregoing description of the Merger
Agreement is qualified in its entirety by reference to the full text of the
Merger Agreement.

          The copy of the form of Voting Agreement is filed as Exhibit 9 to this
Statement and is incorporated by reference herein. The foregoing description of
the Voting Agreement is qualified in its entirety by reference to the full text
of the form of Voting Agreement.

          To the extent such information was available on the date hereof, to
the knowledge of each Reporting Person on the date hereof, except as set forth
herein or in the Exhibits filed herewith, none of the persons named in Item 2 or
on Schedule A hereto has any other contracts, arrangements, understandings or

                            VOTING SUPPORT AGREEMENT
                            ------------------------

     VOTING SUPPORT AGREEMENT ("Agreement"), dated September 28, 1999, by
and between SLC TECHNOLOGIES, INC., a Delaware corporation ("SLC"), and Thomas
L. Auth ("Stockholder").

     A.   The Board of Directors of ITI Technologies, Inc., a Delaware
corporation (the "Company"), has previously approved, and concurrently herewith
SLC and the Company are entering into, an Agreement and Plan of Merger and
Reorganization of even date herewith (as the same may be amended from time to
time, the "Merger Agreement"), pursuant to which SLC is to be merged with and
into the Company (the "Merger"). Capitalized terms used but not defined herein
have the meanings ascribed thereto in the Merger Agreement.

     B.   As of the date hereof, Stockholder is the record and beneficial owner
of 111,266 shares of Common Stock, par value $0.01 per share, of ITI (such
shares together with any other shares of Common Stock acquired after the date
hereof being collectively referred to herein as the "Shares").

     C.   As a condition to its willingness to enter into the Merger Agreement
SLC has required that Stockholder agree to vote the Shares as hereinafter
specified, all on the terms and conditions provided for herein.

     In consideration of the mutual covenants and agreements contained
herein and intending to be legally bound hereby, the parties agree as follows:

1.   Agreement to Vote; Proxy.
     ------------------------

     (a)  Voting.  At any meeting of the stockholders of the Company however
          ------
called (or any action by consent in lieu of a meeting), Stockholder shall vote
the Shares or cause them to be voted (i) in favor of the Merger; (ii) against
any action or agreement that would result in a breach in any material respect of
any covenant, representation or warranty or any other obligation or agreement of
the Company under the Merger Agreement; and (iii) against any action or
agreement (other than the Merger Agreement or the transactions contemplated
thereby) that would impede, interfere with, delay, postpone or attempt to
discourage the Merger including, but not limited to: (A) any extraordinary
corporate transaction, such as a merger, consolidation or other business
combination involving the Company and the Subsidiaries; (B) a sale or transfer
of a material amount of assets of the Company and the Subsidiaries or a
reorganization, recapitalization or liquidation of the Company and the
Subsidiaries; (C) any change in the management or the board of directors of the
Company, except as otherwise agreed to in writing by SLC; (D) any material
change in the present capitalization or dividend policy of the Company; or (E)
any other material change in the Company's corporate structure or business.
<PAGE>

          (b)  Proxy.  Stockholder hereby grants to SLC a proxy to vote the
               -----
Shares as indicated in subsection (a) (or to take action by written consent in
lieu of such vote); provided that such proxy shall terminate upon the valid and
effective termination of this Agreement pursuant to Section 2 hereof.
Stockholder intends this proxy to be irrevocable and coupled with an interest
and will take such further action or execute such other instruments as may be
necessary to effectuate the intent of this proxy and hereby revokes any proxy
previously granted by Stockholder with respect to the Shares (other than to
another party subject to an agreement with SLC identical to this Agreement, to
the extent necessary to accomplish such party's granting of a proxy to SLC);
provided that such proxy shall terminate upon the valid and effective
termination of this Agreement pursuant to Section 2 hereof.

          (c)  No Alternative Disposition.  Except as specifically permitted by
               --------------------------
Section 5(b) hereof, Stockholder will not contract to sell, sell or otherwise
transfer or dispose of any Shares, or any interest therein or securities
convertible thereunto or any voting rights with respect thereto, other than
pursuant to the Merger, without first having obtained SLC's written consent.
Except as specifically permitted by Section 5(b) hereof, Stockholder will not
take any action that would adversely affect the voting power of any of the
Shares.

     2.   Termination.  This Agreement shall terminate on the first to occur
          -----------
of (a) the Effective Time, (b) the valid and effective termination of the Merger
Agreement in accordance with its terms; provided, however, that if such
termination is pursuant to Section 7.1(e), (f) or (g) of the Merger Agreement,
this Agreement shall not terminate until ITI has paid SLC $10,000,000 pursuant
to Section 5.6(b) of the Merger Agreement, and (c) written notice of termination
of this Agreement by SLC to Stockholder; provided further that nothing contained
in this Section 2 shall relieve Stockholder from any liability for any willful
breach of this Agreement prior to such termination.

     3.   Representation and Warranties of SLC.  SLC hereby represents and
          ------------------------------------
warrants to Stockholder as follows:

          (a)  Organization and Existence.  SLC is a corporation duly

Delaware and has the requisite corporate power to carry on its business as it is
now being conducted.

          (b)  Authority Relative to this Agreement.  SLC has all requisite
               ------------------------------------
corporate power and authority to execute and deliver this Agreement and to

and validly executed and delivered by SLC and, assuming this

                                      -2-

Agreement constitutes a valid and binding obligation of Stockholder, this
Agreement constitutes a valid and binding agreement of SLC enforceable against
it in accordance with its terms.

          (c)  Consents and Approvals; No Violation.  Neither the execution and
               ------------------------------------
delivery of this Agreement by SLC nor the consummation of the transactions
contemplated hereby will (i) conflict with or result in any breach of any
provision of SLC's certificate of incorporation or bylaws, (ii) require any
consent, approval, authorization or permit of, or filing with or notification
to, any governmental or regulatory authority, except (A) in connection with the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "H-S-R
Act"), (B) such filings and approvals as may be required under the Securities
Exchange Act of 1934, as amended (the "Exchange Act") or the "blue sky",
takeover or securities laws of various states, or (C) where the failure to
obtain such consent, approval, authorization or permit, or to make such filing
or notification, would not prevent or delay consummation of the transactions
contemplated by this Agreement or would not otherwise prevent SLC from
performing its obligations under this Agreement; (iii) result in a default (or
give rise to any right of termination, cancellation or acceleration) under any
of the terms, conditions or provisions of any license, agreement or other
instrument or obligation to which SLC or any of SLC's subsidiaries is a party or
by which any of them or any of their respective assets may be bound, except for
such defaults (or rights of termination, cancellation or acceleration) as to
which requisite waivers or consents have been obtained or which, in the
aggregate, would not result in a material adverse effect on SLC; or (iv) violate
any order, writ, injunction, decree, statute, rule or regulation applicable to
SLC, any of SLC's other subsidiaries or any of their respective assets, except
for violations which would not result in a material adverse effect on SLC.

          ---------------------------------------------
represents and warrants to SLC as follows:

     (a)  Ownership of Shares.  Stockholder owns of record the number of
          -------------------
Shares set forth in the preamble hereto and such Shares constitute all of the
shares of Common Stock of the Company owned of record by Stockholder.
Stockholder has sole voting power and sole power of disposition with respect to
all of such Shares, with no restrictions on Stockholder's rights of voting or
disposition pertaining thereto and no other person or entity has any right to
direct Stockholder with respect to voting any of the Shares or approve the
voting by Stockholder of any of the Shares or has any right to approve any
amendment or modification of this Agreement. Stockholder owns all of the Shares,

<PAGE>

Agreement by Stockholder and the consummation by Stockholder of the transactions
contemplated hereby have been duly and validly authorized by Stockholder and no
other proceedings on the part of Stockholder or any of the Affiliates of

binding agreement of Stockholder enforceable against Stockholder in accordance
with its terms.

          (c)  Consents and Approvals; No Violation.  Neither the execution and

or regulatory authority, except (A) in connection with the H-S-R Act or under
the Exchange Act, or (B) where the failure to obtain such consent, approval,

right of termination, cancellation or acceleration) under any of the terms,

<PAGE>

          (b)  Restriction on Transfer, Proxies and Non-Interference.  While
               -----------------------------------------------------
this Agreement is in effect, Stockholder shall not sell, transfer, pledge,
encumber, assign or otherwise dispose of, or enter into any contract, option or
other arrangement or understanding with respect to the sale, transfer, pledge,
encumbrance, assignment or other disposition of any of the Shares (each of the
foregoing, a "Transfer") unless, in connection with such Transfer, the
transferee executes an agreement, in form and substance satisfactory to SLC,
pursuant to which such transferee agrees to be bound by the terms and provisions
of this Agreement applicable to Stockholder and grants to SLC the proxy
described in Section 1(b) of this Agreement; provided, however, that
                                             --------  -------
Stockholder may transfer Shares received as a result of the exercise of options
on or after the date hereof so long as such Shares are transferred to a third
party not affiliated with Stockholder in a brokers' transaction (as such term is
defined in Rule 144 promulgated under the Securities Act of 1933, as amended) in
connection with such exercise. While this Agreement is in effect, and except as
contemplated hereby, Stockholder will not, and shall cause Stockholder's
Affiliates to not (i) grant any proxies, deposit any Shares into a voting trust
or enter into a Voting Support Agreement with respect to any of the Shares or
(ii) take any action that would make any representation or warranty of
Stockholder contained herein untrue or incorrect or have the effect of
preventing or disabling Stockholder from performing Stockholder's obligations
under this Agreement.

          (c)  Additional Shares.  While this Agreement is in effect,
               -----------------
Stockholder will promptly notify SLC of the number of any new Shares acquired or
beneficially owned by Stockholder or Stockholder's Affiliates, if any, after the
date hereof. Any such shares shall become Shares for purposes of this Agreement.

     6.   Further Assurances.  From time to time, at any other party's
          ------------------
request and without further consideration, each party hereto shall execute and
deliver such additional documents and take all such further action as may be
reasonably required to consummate and make effective, in the most expeditious
manner practicable, the transactions contemplated by this Agreement. All
certificates representing Shares shall bear, until the termination of this
Agreement, in a conspicuous place the following legend, except that in the event
Stockholder transfers Shares pursuant to a brokers' transaction in accordance
with Section 5(b) hereof such legend shall be removed with respect to such
transferred Shares:

   The Shares represented by this certificate may not be sold, exchanged or
   otherwise transferred or disposed of except in compliance with the terms and
   conditions of the Voting Support Agreement, dated as of September 28, 1999,
   between SLC Technologies, Inc. and Thomas L. Auth.

     7.   Stop Transfer Order.  In furtherance of this Agreement, Stockholder
          -------------------
hereby authorizes the Company's counsel to notify the Company's transfer agent
that a stop

                                      -5-
<PAGE>

transfer order is to be entered with respect to all of the Shares (and that this
Agreement places limits on the voting and transfer of the Shares), except with
respect to Shares that Stockholder transfers pursuant to a brokers' transaction
in accordance with Section 5(b).

     8.   Miscellaneous.
          -------------

          (a)  Entire Agreement; Assignment.  This Agreement (i) constitutes
               ----------------------------
the entire agreement among the parties with respect to the subject matter hereof
and supersedes all other prior agreements and understandings, both written and
oral, among the parties with respect to the subject matter hereof and (ii) shall
not be assigned by operation of law or otherwise, provided that SLC may assign
its rights and obligations hereunder to any subsidiary of SLC, but no such
assignment shall relieve SLC of its obligations hereunder if such assignee does
not perform such obligations.

          (b)  Amendments.  This Agreement may not be modified, amended,
               ----------
altered or supplemented, except upon the execution and delivery of a written
agreement executed by the parties hereto.

          (c)  Governing Law.  This Agreement shall be governed by and
               -------------
construed in accordance with the internal laws of the State of Delaware.

          (d)  Specific Performance.  Each of the parties hereto recognizes and
               --------------------
acknowledges that a breach by Stockholder of any covenants or agreements
contained in this Agreement will cause SLC to sustain damages for which it would
not have an adequate remedy at law for money damages, and therefore in the event
of any such breach SLC shall be entitled to the remedy of specific performance
of such covenants and agreements and injunctive and other equitable relief in
addition to any other remedy to which it may be entitled, at law or in equity.

          (e)  Counterparts.  This Agreement may be executed in any number of
               ------------
counterparts, each of which shall be deemed to be an original, with the same
effect as if the signatures thereto and hereto were upon the same instrument.

          (f)  Descriptive Headings.  The descriptive headings used herein are
               --------------------
inserted for convenience of reference only and are not intended to be part of or
to affect the meaning or interpretation of this Agreement.

          (g)  Severability.  Whenever possible, each provision or portion of
               ------------
any provision of this Agreement will be interpreted in such manner as to be
effective and valid under applicable law, but if any provision or portion of any
provision of this Agreement is held to be invalid, illegal or unenforceable in
any respect under any applicable law or rule in any

                                      -6-
<PAGE>

jurisdiction, such invalidity, illegality or unenforceability will not affect
any other provision or portion of any provision in such jurisdiction, and this
Agreement will be reformed, construed and enforced in such jurisdiction as if
such invalid, illegal or unenforceable provision or portion of any provision had
never been contained herein.

          VOTING SUPPORT AGREEMENT ("Agreement"), dated September 28, 1999, by
and between SLC TECHNOLOGIES, INC., a Delaware corporation ("SLC"), and Auth
Family Limited Partnership ("Stockholder").

          A.    The Board of Directors of ITI Technologies, Inc., a Delaware
corporation (the "Company"), has previously approved, and concurrently herewith
SLC and the Company are entering into, an Agreement and Plan of Merger and
Reorganization of even date herewith (as the same may be amended from time to
time, the "Merger Agreement"), pursuant to which SLC is to be merged with and
into the Company (the "Merger"). Capitalized terms used but not defined herein
have the meanings ascribed thereto in the Merger Agreement.

          B.    As of the date hereof, Stockholder is the record and beneficial
owner of 125,000 shares of Common Stock, par value $0.01 per share, of ITI (such
shares together with any other shares of Common Stock acquired after the date
hereof being collectively referred to herein as the "Shares").

          C.    As a condition to its willingness to enter into the Merger
Agreement SLC has required that Stockholder agree to vote the Shares as
hereinafter specified, all on the terms and conditions provided for herein.

          In consideration of the mutual covenants and agreements contained
herein and intending to be legally bound hereby, the parties agree as follows:

          1.    Agreement to Vote; Proxy.
                ------------------------

                (a)  Voting.  At any meeting of the stockholders of the Company
                     ------
however called (or any action by consent in lieu of a meeting), Stockholder
shall vote the Shares or cause them to be voted (i) in favor of the Merger; (ii)
against any action or agreement that would result in a breach in any material
respect of any covenant, representation or warranty or any other obligation or
agreement of the Company under the Merger Agreement; and (iii) against any
action or agreement (other than the Merger Agreement or the transactions
contemplated thereby) that would impede, interfere with, delay, postpone or
attempt to discourage the Merger including, but not limited to: (A) any
extraordinary corporate transaction, such as a merger, consolidation or other
business combination involving the Company and the Subsidiaries; (B) a sale or
transfer of a material amount of assets of the Company and the Subsidiaries or a
reorganization, recapitalization or liquidation of the Company and the
Subsidiaries; (C) any change in the management or the board of directors of the
Company, except as otherwise agreed to in writing by SLC; (D) any material
change in the present capitalization or dividend policy of the Company; or (E)
any other material change in the Company's corporate structure or business.

                (b)  Proxy. Stockholder hereby grants to SLC a proxy to vote the
                     -----
Shares as indicated in subsection (a) (or to take action by written consent in
lieu of such vote); provided that such proxy shall terminate upon the valid and
effective termination of this Agreement pursuant to Section 2 hereof.
Stockholder intends this proxy to be irrevocable and coupled with an interest
and will take such further action or execute such other instruments as may be
necessary to effectuate the intent of this proxy and hereby revokes any proxy
previously granted by Stockholder with respect to the Shares (other than to
another party subject to an agreement with SLC identical to this Agreement, to
the extent necessary to accomplish such party's granting of a proxy to SLC);
provided that such proxy shall terminate upon the valid and effective
termination of this Agreement pursuant to Section 2 hereof.

                (c)  No Alternative Disposition. Except as specifically
                     --------------------------
permitted by Section 5(b) hereof, Stockholder will not contract to sell, sell or
otherwise transfer or dispose of any Shares, or any interest therein or
securities convertible thereunto or any voting rights with respect thereto,
other than pursuant to the Merger, without first having obtained SLC's written
consent. Except as specifically permitted by Section 5(b) hereof, Stockholder
will not take any action that would adversely affect the voting power of any of
the Shares.

          2.    Termination. This Agreement shall terminate on the first to
                -----------
occur of (a) the Effective Time, (b) the valid and effective termination of the
Merger Agreement in accordance with its terms; provided, however, that if such
termination is pursuant to Section 7.1(e), (f) or (g) of the Merger Agreement,
this Agreement shall not terminate until ITI has paid SLC $10,000,000 pursuant
to Section 5.6(b) of the Merger Agreement, and (c) written notice of termination
of this Agreement by SLC to Stockholder; provided further that nothing contained
in this Section 2 shall relieve Stockholder from any liability for any willful
breach of this Agreement prior to such termination.

                ------------------------------------

give rise to any right of termination, cancellation or acceleration) under any
of the terms, conditions or provisions of any license, agreement or other
instrument or obligation to which SLC or any of SLC's subsidiaries is a party or

any order, writ, injunction, decree, statute, rule or regulation applicable to

encumber, assign or otherwise dispose of, or enter into any contract, option or
other arrangement or understanding with respect to the sale, transfer, pledge,
encumbrance, assignment or other disposition of any of the Shares (each of the
foregoing, a "Transfer") unless, in connection with such Transfer, the
transferee executes an agreement, in form and substance satisfactory to SLC,
pursuant to which such transferee agrees to be bound by the terms and provisions
of this Agreement applicable to Stockholder and grants to SLC the proxy
described in Section 1(b) of this Agreement; provided, however, that Stockholder

may transfer Shares received as a result of the exercise of options on or after
the date hereof so long as such Shares are transferred to a third party not
affiliated with Stockholder in a brokers' transaction (as such term is defined
in Rule 144 promulgated under the Securities Act of 1933, as amended) in
connection with such exercise. While this Agreement is in effect, and except as
contemplated hereby, Stockholder will not, and shall cause Stockholder's
Affiliates to not (i) grant any proxies, deposit any Shares into a voting trust
or enter into a Voting Support Agreement with respect to any of the Shares or

under this Agreement.

                (c)  Additional Shares. While this Agreement is in effect,
                     -----------------
Stockholder will promptly notify SLC of the number of any new Shares acquired or
beneficially owned by Stockholder or Stockholder's Affiliates, if any, after the
date hereof. Any such shares shall become Shares for purposes of this Agreement.

          6.    Further Assurances. From time to time, at any other party's
                ------------------
request and without further consideration, each party hereto shall execute and

reasonably required to consummate and make effective, in the most expeditious
manner practicable, the transactions contemplated by this Agreement. All
certificates representing Shares shall bear, until the termination of this
Agreement, in a conspicuous place the following legend, except that in the event
Stockholder transfers Shares pursuant to a brokers' transaction in accordance
with Section 5(b) hereof such legend shall be removed with respect to such
transferred Shares:

       The Shares represented by this certificate may not be sold, exchanged or
       otherwise transferred or disposed of except in compliance with the terms
       and conditions of the Voting Support Agreement, dated as of September 28,
       1999, between SLC Technologies, Inc. and Auth Family Limited Partnership.

                -------------------
Stockholder hereby authorizes the Company's counsel to notify the Company's
transfer agent that a stop

                                      -5-
<PAGE>

transfer order is to be entered with respect to all of the Shares (and that this
Agreement places limits on the voting and transfer of the Shares), except with
respect to Shares that Stockholder transfers pursuant to a brokers' transaction
in accordance with Section 5(b).

          8.    Miscellaneous.
                -------------

                (a)  Entire Agreement; Assignment. This Agreement (i)

constitutes the entire agreement among the parties with respect to the subject
matter hereof and supersedes all other prior agreements and understandings, both
written and oral, among the parties with respect to the subject matter hereof
and (ii) shall not be assigned by operation of law or otherwise, provided that
SLC may assign its rights and obligations hereunder to any subsidiary of SLC,
but no such assignment shall relieve SLC of its obligations hereunder if such
assignee does not perform such obligations.

                (b)  Amendments. This Agreement may not be modified, amended,
                     ----------
altered or supplemented, except upon the execution and delivery of a written
agreement executed by the parties hereto.

                (c)  Governing Law. This Agreement shall be governed by and

                     --------------------
and acknowledges that a breach by Stockholder of any covenants or agreements
contained in this Agreement will cause SLC to sustain damages for which it would
not have an adequate remedy at law for money damages, and therefore in the event
of any such breach SLC shall be entitled to the remedy of specific performance
of such covenants and agreements and injunctive and other equitable relief in
addition to any other remedy to which it may be entitled, at law or in equity.

                (e)  Counterparts. This Agreement may be executed in any number

                     ------------
of any provision of this Agreement will be interpreted in such manner as to be
effective and valid under applicable law, but if any provision or portion of any
provision of this Agreement is held to be invalid, illegal or unenforceable in
any respect under any applicable law or rule in any

jurisdiction, such invalidity, illegality or unenforceability will not affect
any other provision or portion of any provision in such jurisdiction, and this

never been contained herein.

SLC and the Company are entering into, an Agreement and Plan of Merger and
Reorganization of even date herewith (as the same may be amended from time to

into the Company (the "Merger"). Capitalized terms used but not defined herein
have the meanings ascribed thereto in the Merger Agreement.

          B.    As of the date hereof, Stockholder is the record and beneficial
owner of 42,656 shares of Common Stock, par value $0.01 per share, of ITI (such

          C.    As a condition to its willingness to enter into the Merger

however called (or any action by consent in lieu of a meeting), Stockholder
shall vote the Shares or cause them to be voted (i) in favor of the Merger; (ii)
against any action or agreement that would result in a breach in any material
respect of any covenant, representation or warranty or any other obligation or
agreement of the Company under the Merger Agreement; and (iii) against any
action or agreement (other than the Merger Agreement or the transactions
contemplated thereby) that would impede, interfere with, delay, postpone or
attempt to discourage the Merger including, but not limited to: (A) any
extraordinary corporate transaction, such as a merger, consolidation or other
business combination involving the Company and the Subsidiaries; (B) a sale or
transfer of a material amount of assets of the Company and the Subsidiaries or a
reorganization, recapitalization or liquidation of the Company and the
Subsidiaries; (C) any change in the management or the board of directors of the
Company, except as otherwise agreed to in writing by SLC; (D) any material
change in the present capitalization or dividend policy of the Company; or (E)
any other material change in the Company's corporate structure or business.
<PAGE>

                (b)  Proxy. Stockholder hereby grants to SLC a proxy to vote the
                     -----
Shares as indicated in subsection (a) (or to take action by written consent in
lieu of such vote); provided that such proxy shall terminate upon the valid and
effective termination of this Agreement pursuant to Section 2 hereof.
Stockholder intends this proxy to be irrevocable and coupled with an interest
and will take such further action or execute such other instruments as may be
necessary to effectuate the intent of this proxy and hereby revokes any proxy
previously granted by Stockholder with respect to the Shares (other than to
another party subject to an agreement with SLC identical to this Agreement, to
the extent necessary to accomplish such party's granting of a proxy to SLC);
provided that such proxy shall terminate upon the valid and effective
termination of this Agreement pursuant to Section 2 hereof.

                (c)  No Alternative Disposition. Stockholder will not contract
                     --------------------------

therein or securities convertible thereunto or any voting rights with respect
thereto, other than pursuant to the Merger, without first having obtained SLC's
written consent. Stockholder will not take any action that would adversely
affect the voting power of any of the Shares.

          2.    Termination. This Agreement shall terminate on the first to
                -----------

Merger Agreement in accordance with its terms; provided, however, that if such
termination is pursuant to Section 7.1(e), (f) or (g) of the Merger Agreement,
this Agreement shall not terminate until ITI has paid SLC $10,000,000 pursuant
to Section 5.6(b) of the Merger Agreement, and (c) written notice of termination
of this Agreement by SLC to Stockholder; provided further that nothing contained
in this Section 2 shall relieve Stockholder from any liability for any willful
breach of this Agreement prior to such termination.

written and oral, among the parties with respect to the subject matter hereof
and (ii) shall not be assigned by operation of law or otherwise, provided that

assignee does not perform such obligations.

                (b)  Amendments. This Agreement may not be modified, amended,
                     ----------
altered or supplemented, except upon the execution and delivery of a written

                     --------------------
and acknowledges that a breach by Stockholder of any covenants or agreements
contained in this Agreement will cause SLC to sustain damages for which it would
not have an adequate remedy at law for money damages, and therefore in the event

of such covenants and agreements and injunctive and other equitable relief in
addition to any other remedy to which it may be entitled, at law or in equity.

                (e)  Counterparts. This Agreement may be executed in any number

                     ------------
of any provision of this Agreement will be interpreted in such manner as to be
effective and valid under applicable law, but if any provision or portion of any
provision of this Agreement is held to be invalid, illegal or unenforceable in
any respect under any applicable law or rule in any jurisdiction, such
invalidity, illegality or unenforceability will not affect any other provision
or portion of any provision in such jurisdiction, and this Agreement will be
reformed, construed and enforced in such jurisdiction as if such invalid,
illegal or unenforceable provision or portion of any provision had never been
contained herein.

                            VOTING SUPPORT AGREEMENT
                            ------------------------

          VOTING SUPPORT AGREEMENT ("Agreement"), dated September 28, 1999, by
and between SLC TECHNOLOGIES, INC., a Delaware corporation ("SLC"), and Perry J.
Lewis ("Stockholder").

          A.    The Board of Directors of ITI Technologies, Inc., a Delaware
corporation (the "Company"), has previously approved, and concurrently herewith
SLC and the Company are entering into, an Agreement and Plan of Merger and
Reorganization of even date herewith (as the same may be amended from time to
time, the "Merger Agreement"), pursuant to which SLC is to be merged with and
into the Company (the "Merger"). Capitalized terms used but not defined herein
have the meanings ascribed thereto in the Merger Agreement.

          B.    As of the date hereof, Stockholder is the record and beneficial
owner of 47,656 shares of Common Stock, par value $0.01 per share, of ITI (such
shares together with any other shares of Common Stock acquired after the date
hereof being collectively referred to herein as the "Shares").

          C.    As a condition to its willingness to enter into the Merger
Agreement SLC has required that Stockholder agree to vote the Shares as
hereinafter specified, all on the terms and conditions provided for herein.

          In consideration of the mutual covenants and agreements contained
herein and intending to be legally bound hereby, the parties agree as follows:

          1.    Agreement to Vote; Proxy.
                ------------------------

                (a)  Voting. At any meeting of the stockholders of the Company
                     ------
however called (or any action by consent in lieu of a meeting), Stockholder
shall vote the Shares or cause them to be voted (i) in favor of the Merger; (ii)
against any action or agreement that would result in a breach in any material
respect of any covenant, representation or warranty or any other obligation or
agreement of the Company under the Merger Agreement; and (iii) against any
action or agreement (other than the Merger Agreement or the transactions
contemplated thereby) that would impede, interfere with, delay, postpone or
attempt to discourage the Merger including, but not limited to: (A) any
extraordinary corporate transaction, such as a merger, consolidation or other
business combination involving the Company and the Subsidiaries; (B) a sale or
transfer of a material amount of assets of the Company and the Subsidiaries or a
reorganization, recapitalization or liquidation of the Company and the
Subsidiaries; (C) any change in the management or the board of directors of the
Company, except as otherwise agreed to in writing by SLC; (D) any material
change in the present capitalization or dividend policy of the Company; or (E)
any other material change in the Company's corporate structure or business.
<PAGE>

           (b)  Proxy. Stockholder hereby grants to SLC a proxy to vote the
                -----
Shares as indicated in subsection (a) (or to take action by written consent in
lieu of such vote); provided that such proxy shall terminate upon the valid and
effective termination of this Agreement pursuant to Section 2 hereof.
Stockholder intends this proxy to be irrevocable and coupled with an interest
and will take such further action or execute such other instruments as may be
necessary to effectuate the intent of this proxy and hereby revokes any proxy
previously granted by Stockholder with respect to the Shares (other than to
another party subject to an agreement with SLC identical to this Agreement, to
the extent necessary to accomplish such party's granting of a proxy to SLC);
provided that such proxy shall terminate upon the valid and effective
termination of this Agreement pursuant to Section 2 hereof.

           (c)  No Alternative Disposition. Stockholder will not contract to
                --------------------------
sell, sell or otherwise transfer or dispose of any Shares, or any interest
therein or securities convertible thereunto or any voting rights with respect
thereto, other than pursuant to the Merger, without first having obtained SLC's
written consent. Stockholder will not take any action that would adversely
affect the voting power of any of the Shares.

     2.    Termination. This Agreement shall terminate on the first to occur of
           -----------
(a) the Effective Time, (b) the valid and effective termination of the Merger
Agreement in accordance with its terms; provided, however, that if such
termination is pursuant to Section 7.1(e), (f) or (g) of the Merger Agreement,
this Agreement shall not terminate until ITI has paid SLC $10,000,000 pursuant
to Section 5.6(b) of the Merger Agreement, and (c) written notice of termination
of this Agreement by SLC to Stockholder; provided further that nothing contained
in this Section 2 shall relieve Stockholder from any liability for any willful
breach of this Agreement prior to such termination.

     3.    Representation and Warranties of SLC. SLC hereby represents and
           ------------------------------------
warrants to Stockholder as follows:

           (a)  Organization and Existence. SLC is a corporation duly organized,
                --------------------------
validly existing and in good standing under the laws of the State of Delaware
and has the requisite corporate power to carry on its business as it is now
being conducted.

           (b)  Authority Relative to this Agreement. SLC has all requisite
                ------------------------------------
corporate power and authority to execute and deliver this Agreement and to
perform its obligations hereunder. The execution and delivery by SLC of this
Agreement have been duly and validly authorized by SLC, and no other corporate
proceedings on the part SLC are necessary to authorize this Agreement or to
consummate the transactions contemplated hereby. This Agreement has been duly
and validly executed and delivered by SLC and, assuming this

                                      -2-
<PAGE>

Agreement constitutes a valid and binding obligation of Stockholder, this
Agreement constitutes a valid and binding agreement of SLC enforceable against
it in accordance with its terms.

           (c)  Consents and Approvals; No Violation. Neither the execution and
                ------------------------------------
delivery of this Agreement by SLC nor the consummation of the transactions
contemplated hereby will (i) conflict with or result in any breach of any
provision of SLC's certificate of incorporation or bylaws, (ii) require any
consent, approval, authorization or permit of, or filing with or notification
to, any governmental or regulatory authority, except (A) in connection with the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "H-S-R
Act"), (B) such filings and approvals as may be required under the Securities
Exchange Act of 1934, as amended (the "Exchange Act") or the "blue sky",
takeover or securities laws of various states, or (C) where the failure to
obtain such consent, approval, authorization or permit, or to make such filing
or notification, would not prevent or delay consummation of the transactions
contemplated by this Agreement or would not otherwise prevent SLC from
performing its obligations under this Agreement; (iii) result in a default (or
give rise to any right of termination, cancellation or acceleration) under any
of the terms, conditions or provisions of any license, agreement or other
instrument or obligation to which SLC or any of SLC's subsidiaries is a party or
by which any of them or any of their respective assets may be bound, except for
such defaults (or rights of termination, cancellation or acceleration) as to
which requisite waivers or consents have been obtained or which, in the

                --------------------

of such covenants and agreements and injunctive and other equitable relief in
addition to any other remedy to which it may be entitled, at law or in equity.

           (e)  Counterparts.  This Agreement may be executed in any number of

                ------------
any provision of this Agreement will be interpreted in such manner as to be
effective and valid under applicable law, but if any provision or portion of any
provision of this Agreement is held to be invalid, illegal or unenforceable in
any respect under any applicable law or rule in any jurisdiction, such

                            VOTING SUPPORT AGREEMENT
                            ------------------------

     VOTING SUPPORT AGREEMENT ("Agreement"), dated September 28, 1999, by
and between SLC TECHNOLOGIES, INC., a Delaware corporation ("SLC"), and MLGA
Fund II, L.P. ("Stockholder").

     A.   The Board of Directors of ITI Technologies, Inc., a Delaware
corporation (the "Company"), has previously approved, and concurrently herewith
SLC and the Company are entering into, an Agreement and Plan of Merger and
Reorganization of even date herewith (as the same may be amended from time to
time, the "Merger Agreement"), pursuant to which SLC is to be merged with and
into the Company (the "Merger"). Capitalized terms used but not defined herein
have the meanings ascribed thereto in the Merger Agreement.

     B.   As of the date hereof, Stockholder is the record and beneficial owner
of 1,281,159 shares of Common Stock, par value $0.01 per share, of ITI (such
shares together with any other shares of Common Stock acquired after the date
hereof being collectively referred to herein as the "Shares").

     C.   As a condition to its willingness to enter into the Merger Agreement
SLC has required that Stockholder agree to vote the Shares as hereinafter
specified, all on the terms and conditions provided for herein.

          In consideration of the mutual covenants and agreements contained
herein and intending to be legally bound hereby, the parties agree as follows:

          1.   Agreement to Vote; Proxy.
               ------------------------

               (a)  Voting.  At any meeting of the stockholders of the Company
                    ------
however called (or any action by consent in lieu of a meeting), Stockholder
shall vote the Shares or cause them to be voted (i) in favor of the Merger; (ii)
against any action or agreement that would result in a breach in any material
respect of any covenant, representation or warranty or any other obligation or
agreement of the Company under the Merger Agreement; and (iii) against any
action or agreement (other than the Merger Agreement or the transactions
contemplated thereby) that would impede, interfere with, delay, postpone or
attempt to discourage the Merger including, but not limited to: (A) any
extraordinary corporate transaction, such as a merger, consolidation or other
business combination involving the Company and the Subsidiaries; (B) a sale or
transfer of a material amount of assets of the Company and the Subsidiaries or a
reorganization, recapitalization or liquidation of the Company and the
Subsidiaries; (C) any change in the management or the board of directors of the
Company, except as otherwise agreed to in writing by SLC; (D) any material
change in the present capitalization or dividend policy of the Company; or (E)
any other material change in the Company's corporate structure or business.
<PAGE>

               (b)  Proxy.  Stockholder hereby grants to SLC a proxy to vote
                    -----
the Shares as indicated in subsection (a) (or to take action by written consent
in lieu of such vote); provided that such proxy shall terminate upon the valid
and effective termination of this Agreement pursuant to Section 2 hereof.
Stockholder intends this proxy to be irrevocable and coupled with an interest
and will take such further action or execute such other instruments as may be
necessary to effectuate the intent of this proxy and hereby revokes any proxy
previously granted by Stockholder with respect to the Shares (other than to
another party subject to an agreement with SLC identical to this Agreement, to
the extent necessary to accomplish such party's granting of a proxy to SLC);
provided that such proxy shall terminate upon the valid and effective
termination of this Agreement pursuant to Section 2 hereof.

               (c)  No Alternative Disposition.  Stockholder will not contract
                    --------------------------
to sell, sell or otherwise transfer or dispose of any Shares, or any interest
therein or securities convertible thereunto or any voting rights with respect
thereto, other than pursuant to the Merger, without first having obtained SLC's
written consent. Stockholder will not take any action that would adversely
affect the voting power of any of the Shares.

          2.   Termination.  This Agreement shall terminate on the first to
               -----------
occur of (a) the Effective Time, (b) the valid and effective termination of the
Merger Agreement in accordance with its terms; provided, however, that if such
termination is pursuant to Section 7.1(e), (f) or (g) of the Merger Agreement,
this Agreement shall not terminate until ITI has paid SLC $10,000,000 pursuant
to Section 5.6(b) of the Merger Agreement, and (c) written notice of termination
of this Agreement by SLC to Stockholder; provided further that nothing contained
in this Section 2 shall relieve Stockholder from any liability for any willful
breach of this Agreement prior to such termination.

          3.   Representation and Warranties of SLC.  SLC hereby represents and
               ------------------------------------

or to consummate the transactions contemplated hereby. This Agreement has been
duly and validly executed and delivered by SLC and, assuming this

                                      -2-

Agreement constitutes a valid and binding obligation of Stockholder, this
Agreement constitutes a valid and binding agreement of SLC enforceable against
it in accordance with its terms.

               (c)  Consents and Approvals; No Violation.  Neither the
                    ------------------------------------
execution and delivery of this Agreement by SLC nor the consummation of the
transactions contemplated hereby will (i) conflict with or result in any breach
of any provision of SLC's certificate of incorporation or bylaws, (ii) require
any consent, approval, authorization or permit of, or filing with or
notification to, any governmental or regulatory authority, except (A) in
connection with the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as

under the Securities Exchange Act of 1934, as amended (the "Exchange Act") or
the "blue sky", takeover or securities laws of various states, or (C) where the
failure to obtain such consent, approval, authorization or permit, or to make
such filing or notification, would not prevent or delay consummation of the
transactions contemplated by this Agreement or would not otherwise prevent SLC
from performing its obligations under this Agreement; (iii) result in a default
(or give rise to any right of termination, cancellation or acceleration) under
any of the terms, conditions or provisions of any license, agreement or other
instrument or obligation to which SLC or any of SLC's subsidiaries is a party or
by which any of them or any of their respective assets may be bound, except for
such defaults (or rights of termination, cancellation or acceleration) as to
which requisite waivers or consents have been obtained or which, in the
aggregate, would not result in a material adverse effect on SLC; or (iv) violate
any order, writ, injunction, decree, statute, rule or regulation applicable to
SLC, any of SLC's other subsidiaries or any of their respective assets, except
for violations which would not result in a material adverse effect on SLC.

          4.    Representations and Warranties of Stockholder.  Stockholder
                ---------------------------------------------
hereby represents and warrants to SLC as follows:

and PNC Bank ("PNC") and for the other purposes set forth in the Term Sheet

                                                               -----------

          Based on our review of the Transaction and our discussions with you
and Berwind, we understand that, in connection with the Transaction, you are
interested in obtaining a commitment for $325,000,000 of senior, secured
financing consisting of (i) a $225,000,000 revolving credit facility (the
"Revolving Facility") and (ii) a $100,000,000 term A loan facility (the "Term A

Facility"; the Term A Facility and the Revolving Facility are collectively
- --------
referred to as the "Credit Facilities").  The Credit Facilities will be reduced
                    -----------------
in the event the shareholders of Target do not elect to receive cash for the
entire 50% of the outstanding capital stock of Target.  In such event, the
reduced amount of the Cash Election Consideration from that otherwise payable if
such election had been made in full shall be applied to reduce first, the amount
                                                               -----
of the Term A Facility and, second, the amount of the Revolving Facility (but
                            ------
not by more than $25,000,000).

          Scotiabank and PNC are pleased to inform you that they hereby each
commit to provide 50% of the total amount of the Credit Facilities.  Scotiabank
and PNC Capital Markets, Inc. ("PNC Capital Markets") undertake to use
                                -------------------
reasonable commercial efforts to form a syndicate of other financial
institutions

identified by Scotiabank and PNC Capital Markets (together with Scotiabank and
PNC, the "Lenders") that will with the consent of the Borrower (which consent
          -------
shall not be unreasonably withheld), collectively, participate in the Credit
Facilities. Scotiabank and PNC Capital Markets each agrees to act as a joint
lead arranger (in such capacity, a "Joint Lead Arranger") of the Credit
                                    -------------------
Facilities. Scotiabank agrees to act as the syndication agent (in such capacity,
the "Syndication Agent"), and PNC agrees to act as the administrative agent (the
     -----------------
"Administrative Agent", and together with the Syndication Agent, the "Agents"),
 --------------------                                                 ------
for such syndicate of Lenders. The obligations of each Agent and Joint Lead
Arranger hereunder are several and not joint.

          Our commitments, undertakings and agreements hereunder are subject to
the following conditions: (a) the terms and conditions set forth herein and in
the Term Sheet and the provisions set forth in Annex II hereto, (b) the terms
                                               --------
and conditions contained in the confidential fee letter, dated the date hereof
(the "Fee Letter"), between you, Scotiabank, PNC and PNC Capital Markets, (c)
      ----------
prior to and continuing through the Signing Date, (i) trading in securities
generally on the New York Stock Exchange or NASDAQ not having been suspended or
materially limited, (ii) a general moratorium on commercial banking activities
in New York not having been declared by either Federal or state authorities, and
(iii) there not having occurred any outbreak or escalation of hostilities or
other international or domestic calamity, crisis or change in political
financial or economic conditions, the effect of which on the global financial
markets is such as to make it impossible to complete the financing for the
Transaction contemplated by this Commitment Letter, (d) there being no facts,
events or circumstances hereafter arising which come to our attention and
materially adversely affect the consolidated business, assets, liabilities,
financial condition or results of operations of the Target, the Borrower and
their subsidiaries taken as a whole, or the ability of the Borrower to repay the
Credit Facilities and (e) prior to the Funding Date, there being no competing
issuance of debt, securities or commercial bank facilities by the Borrower, the
Target or your or their subsidiaries or on your or their behalf being offered,
placed or arranged except with the prior written consent of Scotiabank and PNC.
In the event any of the foregoing conditions, events or circumstances are not
satisfied, we reserve the right to either terminate our commitments hereunder
(and thereafter have no other or further obligations hereunder or in connection
with the Credit Facility) or to propose alternative financing amounts or
structures that assure adequate protection for the Agents and the Lenders.  You
further agree that, notwithstanding any other provision contained herein or the
Term Sheet, we shall be entitled prior to the Signing Date, after consultation
with you, to change the pricing, terms and structure of the Credit Facilities if
we determine that such changes are advisable in order to ensure a successful
syndication of the Credit Facilities; provided that the total amount of the
                                      --------
Credit Facilities remains sufficient to consummate the Transactions and
<PAGE>

the interest rate margins under the Credit Facilities may not be increased by
more than an additional 2.50% per annum and the Facility Fee may not be
increased by more than $1,625,000. Our commitments hereunder are subject to your
agreement to the foregoing. Furthermore, as a condition to our commitments, you
each agree that no other agents, co-agents or arrangers will be appointed, no
other titles will be awarded and no compensation (other than as expressly set
forth in the Term Sheet and the Fee Letter) will be paid in connection with the
Credit Facilities unless the Borrower, Scotiabank and PNC Capital Markets shall
so agree.

          The Joint Lead Arrangers intend to solicit commitments from the
prospective Lenders promptly following the execution of this Commitment Letter
in an amount sufficient to allow Scotiabank and PNC to achieve their desired
hold levels in the Credit Facilities.  Nonetheless, our commitments are not
subject to syndication of any portion of the Credit Facilities.  The Joint Lead
Arrangers will manage all aspects of the syndication, including, without
limitation, decisions as to the selection of institutions to be approached
(subject to the consent of the Borrower, which consent will not be unreasonably
withheld), and when they will be approached, when their commitments will be
accepted, the allocations of the commitments among the Lenders and the amount
and distribution of fees among the Lenders. In that regard, you agree to
actively assist the Joint Lead Arrangers, in all commercially reasonable
respects, in the syndication of the Credit Facilities, which assistance will
require, among other things, that you provide all information the Joint Lead
Arrangers deem to be reasonably necessary to successfully complete the
syndication, including all the information prepared by you or on your behalf
relating to the Transaction and the business, assets, financial condition,
operations and prospects of the Borrower and Target, as the Joint Lead Arrangers
may deem to be reasonably necessary, and all projections (the "Projections"), as
                                                               -----------
the Joint Lead Arrangers may reasonably request in connection with the
arrangement and syndication of the Credit Facilities.  You hereby represent and
covenant that, to the best of your knowledge, (a) all factual information (the
"Information") that has been or will be made available in writing to the Joint
 -----------
Lead Arrangers or the Agents by you or on your behalf is or will be, when
furnished, complete and correct in all material respects and does not or will
not, when furnished, contain any untrue statement of a material fact or omit to
state a material fact necessary in order to make the statements contained
therein not materially misleading in light of the circumstances under which such
statements are made and (b) the Projections that have been or will be made
available to the Agents and the Joint Lead Arrangers by you or on your behalf
have been or will be prepared in good faith based upon reasonable assumptions.
In arranging and syndicating the Credit Facilities, the Joint Lead Arrangers
will use and rely on the Information and Projections without independent
verification thereof.
<PAGE>

          In addition, you agree to make certain members of your management, as
well as, to the best of your ability, Berwind's management, Target's management,
and each of your, Berwind's and Target's respective consultants and advisors,
available during regular business hours to answer questions regarding the
Transaction and the business, assets, financial condition, operations and
prospects of the Borrower and Target, to review and assist in the preparation of
the syndication memorandum relating to the Credit Facilities, to meet with
prospective Lenders and to use your commercially reasonable efforts to ensure
that our syndication efforts benefit from each of your, Berwind's and Target's
lending relationships.

          By your execution of this Commitment Letter, you hereby indemnify and
hold harmless each Joint Lead Arranger, Scotiabank, PNC, each other Lender
committing to participate in the Credit Facilities and each of our and their
respective affiliates, directors, officers, agents and employees, and agree to
promptly pay all of the reasonable out-of-pocket fees and expenses, in each case
following demand, as set forth in Annex II hereto (with the terms and provisions
                                  --------
of such Annex II hereby being incorporated by reference), whether or not
        --------
definitive credit, security and other documentation (collectively, the "Credit

without limitation, other lenders, underwriters, placement agents, or advisors
or any similar persons), without our prior written consent, except in the case
of those in a confidential relationship to you, Berwind or Target, such as legal
counsel or accountants, to Target and its financial and other advisors (provided
it is supplied to them on a confidential basis with the understanding that it
may not be supplied to any other person (or their financing sources) seeking to
purchase Target) or as required by law or any court or governmental agency (and
in each such event of permitted disclosure you agree promptly to inform us).
This Commitment Letter, the Term Sheet, Annex II hereto and the Fee Letter
                                        --------
constitute the entire understanding among the parties hereto with respect to the
subject matter hereof and thereof and supersede any prior agreements, written or
oral, with respect hereto or thereto.  THIS COMMITMENT LETTER, THE TERM SHEET,
ANNEX II HERETO AND THE FEE LETTER SHALL BE GOVERNED BY AND CONSTRUED IN

ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK.  EACH OF THE
UNDERSIGNED PARTIES HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVES ANY

Borrower, the other obligors and us  and (iii) following the Signing Date, our

New York time, on May 31, 2000 unless, on or prior to such time all conditions

Scotiabank, PNC and the Borrower agree to cooperate in good faith to promptly
