ITEM 5.  OTHER EVENTS.

         On September 28, 1999, ITI Technologies, Inc., a Delaware corporation
("ITI"), agreed to merge (the "Merger") with SLC Technologies, Inc., a Delaware
corporation ("SLC"). The terms of the Merger are set forth in an Agreement and
Plan of Merger and Reorganization (the "Merger Agreement") dated as of September
28, 1998 between SLC and ITI. In the Merger, SLC's outstanding common stock will
be converted into 15,170,640 shares of ITI's common stock. ITI stockholders may
elect to receive $36.50 in cash at closing for each share of ITI common stock
owned, subject to the limitation that no more than 50 percent of the total
number of shares of ITI common stock outstanding immediately prior to the
closing will be exchanged for cash. If ITI stockholders elect to exchange more
than 50 percent of the outstanding shares of ITI 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 ITI common stock immediately prior to the closing are
exchanged for cash. As a result of the transaction, the current stockholder of
SLC, Berwind Group Partnership, will have a 63.5 percent ownership interest in
ITI (on an equivalent shares basis calculated under the treasury stock method),
without giving effect to the cash election, or 78 percent ownership stake after
giving effect to the cash election and assuming that 50 percent of the
outstanding shares of ITI common stock are exchanged for cash.

         The transaction 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 ITI; (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 the Merger Agreement, certain ITI stockholders have
entered into agreements 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.

         A copy of the Merger Agreement is attached as Exhibit 2.1 hereto 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.

and is incorporated by reference herein. The foregoing description of the Rights
Plan is qualified in its entirety by reference to the full text of the Rights

corporation ("ITI"), and SLC TECHNOLOGIES, INC., a Delaware corporation ("SLC").

                              W I T N E S S E T H:

                  WHEREAS, the respective Boards of Directors of ITI and SLC
have approved and declared advisable the merger of SLC with and into ITI (the
"Merger"), upon the terms and subject to the conditions set forth herein;

                  WHEREAS, the respective Boards of Directors of ITI and SLC
have determined that the Merger is in the best interest of their respective
stockholders;

                  WHEREAS, SLC and its stockholder ("SLC Stockholder") desire to
enter into a transaction pursuant to which the stock of SLC is exchanged for
publicly traded stock;

                  WHEREAS, as an inducement for SLC to enter into this
Agreement, certain stockholders of ITI have entered into one or more Voting
Support Agreements ("Voting Support Agreements");

                  WHEREAS, for federal income tax purposes, it is intended that
the Merger shall qualify as a reorganization within the meaning of Section
368(a) of the Internal Revenue Code of 1986, as amended (the "Code").

                  NOW, THEREFORE, in consideration of the premises,

legally bound, the parties agree as follows:

                                    ARTICLE I

                                   THE MERGER

                  Section 1.1 The Merger. Upon the terms and subject to the
conditions hereof, and in accordance with the Delaware General Corporation Law
(the "DGCL"), SLC shall be merged with and into ITI at the Effective Time (as

accordance with the relevant provisions of the DGCL, is accepted for filing by
with the Secretary of State of the State of Delaware; provided, however, that,
upon mutual consent of the Constituent Corporations, the Certificate of Merger
may provide for a later date of effectiveness of the Merger not more than 30
days after the date the Certificate of Merger is filed. When used in this
Agreement, the term "Effective Time" shall mean the date and time at which the
Certificate of Merger is accepted for record or such later time established by

on the date of the Closing (as defined in Section 1.11).

                  Section 1.3 Effects of the Merger. The Merger shall have the
effects set forth in Section 259 of the DGCL.

                  Section 1.4 Charter and Bylaws; Directors and Officers.

                  (a) At the Effective Time, (i) the Amended and Restated
Certificate of Incorporation of ITI shall be amended as of the Effective Time as
provided in Exhibit A, (ii) the Amended and Restated Certificate of
Incorporation of ITI, as so amended, shall be the Certificate of Incorporation
of the Surviving Corporation until thereafter legally amended as provided
therein or by applicable law and (iii) the Bylaws of ITI, as in effect at the
Effective Time, shall be the Bylaws of the Surviving Corporation until
thereafter legally amended.

                  (b) At the Effective Time, the total number of persons serving
on the Board of Directors of ITI shall be nine (unless otherwise agreed in
writing by the parties hereto prior to the Effective Time), two of whom shall be
Thomas L. Auth and Perry J. Lewis and seven of whom shall be selected solely by
and at the absolute discretion of the Board of Directors of SLC. Thereafter,
membership on the ITI Board of Directors shall be determined in accordance with
the Voting Agreement in the form attached hereto as Exhibit B, which shall be
executed and delivered by the parties thereto at the Effective Time.

                  (c) At the Effective Time, Thomas L. Auth shall be Chairman of
the Board of ITI and Kenneth L. Boyda shall be President and Chief Executive
Officer of ITI.

                  Section 1.5 Conversion of Securities. As of the Effective
Time, by virtue of the Merger and without any action on the part of ITI, SLC or
the holders of any securities of the Constituent Corporations:

                  (a) Each share of the common stock, $0.005 par value, of SLC
(the "SLC Common Stock") issued and outstanding immediately prior to the
Effective Time (other than shares of SLC Common Stock owned by SLC or any wholly
owned Subsidiary of SLC) shall be converted into 15.17064 shares of common
stock, $0.01 par value, of ITI (the "ITI Common Stock") (the "SLC Per Share
Stock Consideration"). If, between the date of this Agreement and the Effective
Time, the outstanding shares of ITI Common Stock or SLC Common Stock are


                                       2
<PAGE>



changed to a different number or class of shares by reason of any stock split,
stock dividend, reverse stock split, reclassification or other similar
transaction, then the SLC Per Share Stock Consideration and the Per Share Cash
Consideration (defined below) shall be appropriately adjusted.

                  (b) Each share of ITI Common Stock issued and outstanding
immediately prior to the Effective Time for which an election is properly made
to receive cash pursuant to Section 1.6 shall be converted into cash in an
amount equal to $36.50 per share and, if on March 28, 2000, the conditions set
forth in Sections 6.1, 6.3(a), 6.3(c), 6.3(e) and 6.3(f) would have been
satisfied or waived if March 28, 2000 were considered to be the Effective Time,
then, if the Effective Time occurs after March 28, 2000, an additional $.25 and
if the Effective Time occurs after April 28, 2000, an additional $.25 (the "Per
Share Cash Consideration" and, together with the SLC Per Share Stock
Consideration, the "Merger Consideration") and subject further to the election,
conversion and proration procedures set forth in Section 1.6; provided, however,
that, notwithstanding the foregoing, if the condition set forth in Section
6.3(d) is satisfied or waived on or prior to March 28, 2000, then no $.25
increase shall be made and, if such condition is met or waived after March 28,
2000 and before April 29, 2000, then only one $.25 increase shall be made.

                  (c) Each share of ITI Common Stock issued and outstanding
immediately prior to the Effective Time and for which no election has been
properly made to receive cash pursuant to Section 1.6 shall remain issued and
outstanding.

                  (d) Each share of SLC Common Stock issued and outstanding
immediately prior to the Effective Time and owned by SLC or any wholly owned
Subsidiary of SLC shall be canceled and extinguished and shall cease to exist,
and no exchange or payment shall be made therefor.

                  Section 1.6 Cash Election Procedures.

                  (a) Subject to Section 1.6(b), each record holder of ITI
Common Stock immediately prior to the Effective Time will be entitled to elect
to receive cash for all or some of the shares of ITI Common Stock ("Cash
Election Shares") held by such record holder. All such elections (each an
"Election") shall be made on a form designated for that purpose by ITI and
reasonably acceptable to SLC (an "Election Form") and in accordance with all
applicable laws. Any shares of ITI Common Stock with respect to which the record
holder thereof shall not, as of the Election Deadline (as defined below), have
properly submitted to the Exchange Agent (as defined below) a properly completed
Election Form shall be deemed not to have elected to receive cash pursuant to
Section 1.5(b) and this Section 1.6. A record holder acting in different
capacities or acting on behalf of other persons in any way shall be entitled to
submit an Election Form for each capacity in which such record holder so acts
with respect to each person for which it so acts. The exchange agent (the
"Exchange Agent") shall be Norwest Bank, N.A., or other reputable bank or trust
company jointly selected by ITI and SLC.

<PAGE>



                  (b) Not later than two business days after the Election
Deadline, ITI shall cause the Exchange Agent to effect the conversions among the
holders of ITI Common Stock of rights to receive the Per Share Cash
Consideration in the Merger as follows: If the aggregate number of Cash Election
Shares properly elected represents more than 50% of the number of shares of ITI
Common Stock issued and outstanding immediately prior to the Effective Time (on
the basis of Election Forms received by the Election Deadline), then the
Exchange Agent shall reduce (pro rata according to each holder's total number of
Cash Election Shares of those holders who made an Election), rounded to the
nearest whole share, a sufficient number of Cash Election Shares such that the
total number of Cash Election Shares represents, as closely as practicable, 50%
of the number of shares of ITI Common Stock issued and outstanding immediately
prior to the Effective Time.

                  (c) Not later than the 25th business day prior to the
anticipated Effective Time or such other date as ITI and SLC may agree in
writing, ITI shall mail an Election Form to each person that was a holder of
record of ITI Common Stock at that time. To be effective, an Election Form must
be properly completed, signed and actually received by the Exchange Agent not
later than 5:00 p.m. prevailing Central Time, on the second business day prior
to the Effective Time (the "Election Deadline") and accompanied by the
certificates representing all the shares of ITI Common Stock ("ITI
Certificates") as to which the Election is being made (or an appropriate
guarantee of delivery by an eligible organization). The Election Form (which
shall specify that delivery shall be effected and the risk of loss and title to
the ITI Certificates (and the payment right represented by such certificates)
shall pass only upon proper delivery of such ITI Certificates to the Exchange
Agent) will advise the holders of ITI Certificates of the procedure for
surrendering to the Exchange Agent such certificates in exchange for the Per
Share Cash Consideration. ITI shall have reasonable discretion, which it may
delegate in whole or in part to the Exchange Agent, to determine whether
Election Forms have been properly completed, signed and timely submitted or to
disregard defects in Election Forms; such decisions of ITI (or of the Exchange
Agent) shall be conclusive and binding. ITI shall consult with SLC on any
significant issues regarding any Election Form. None of SLC, ITI or the Exchange
Agent shall be under any obligation to notify any person of any defect in an
Election Form submitted to the Exchange Agent. The Exchange Agent shall also
make, and ITI shall verify, all computations contemplated by this Section 1.6,
and all such computations shall be conclusive and binding on the holders or
former holders of ITI Common Stock, absent manifest error. The Exchange Agent
shall promptly provide ITI and SLC with a copy of the completed computation.
Shares of ITI Common Stock covered by an Election Form which is not effective
shall be treated as if no Election has been made with respect to such shares of
ITI Common Stock. Once an Election is made it may not be revoked unless such
revocation has been communicated in writing to the Exchange Agent prior to the
Election Deadline. The Exchange Agent shall cause to be properly reissued ITI
Certificates representing ITI Common Stock as to which the Election is not
applicable.

                  Section 1.7 Exchange Procedures.

                  (a) At the Closing, the SLC Stockholder will surrender its
certificates which, immediately prior to the Effective Time, represented
outstanding shares of SLC Common Stock converted in the Merger (the "SLC
Certificates") in exchange for certificates representing ITI Common Stock.
Subject to Section 1.8, upon surrender of a SLC Certificate to ITI for exchange,
together with such other documents as may be reasonably required by ITI
consistent with this Agreement, (i) the holder of such SLC Certificate shall be
entitled to receive in exchange therefore a certificate representing the number
of shares of ITI Common Stock that such holder has the right to receive pursuant
to the provisions of Section 1.5(a) and (ii) the SLC Certificate so surrendered
shall be canceled. Until so surrendered, each SLC Certificate shall be deemed,
from and after the Effective Time, to represent only the right to receive ITI
Common Stock (and cash in lieu of any fractional share of ITI Common Stock) as
contemplated by this Section 1.7 and Section 1.8.

                  (b) At and after the Effective Time, there shall be no further
registration or transfers of shares of SLC Common Stock (other than transfers by
operation of law), and the stock ledgers of SLC shall be closed. After the
Effective Time, SLC Certificates presented to ITI for transfer shall be canceled
and exchanged for the Merger Consideration provided for, without interest, and
in accordance with the procedures set forth, in this Article I.

                  (c) No dividends, interest or other distributions with respect
to the Merger Consideration shall be paid to the holder of any unsurrendered SLC
Certificates until such certificates are surrendered as provided in this Section
1.7. Upon such surrender, there shall be paid, without interest, to the person
in whose name any SLC Certificate is registered all dividends and other
distributions payable in respect of such securities on a date subsequent to, and
in respect of a record date after, the Effective Time.

                  Section 1.8 Additional Exchange Procedures.

                  (a) If any of the Merger Consideration is to be paid or issued
to a person other than the registered holder of the shares of ITI Common Stock
or SLC Common Stock, as the case may be, formerly represented by the
certificates surrendered with respect thereto, it shall be a condition of
payment of the Merger Consideration that the ITI Certificate or Certificates or
the SLC Certificate or Certificates so surrendered shall be properly endorsed or
otherwise be in proper form for transfer and that the person requesting such
payment or issuance shall pay to the Exchange Agent any transfer or other taxes
required as a result of such payment or issuance to a person other than the
registered holder of such shares of ITI Common Stock or SLC Common Stock, as the
case may be, or shall establish to the reasonable satisfaction of the Exchange
Agent that such tax has been paid or is not payable.

<PAGE>



                  (b) In the event that any ITI Certificates or SLC Certificates
shall have been lost, stolen or destroyed, the Exchange Agent or ITI, as the
case may be, shall pay in respect of such lost, stolen or destroyed certificate,
upon the making of an affidavit of that fact by the holder thereof, the Merger
Consideration as may be provided pursuant to this Agreement; provided, however,
that ITI may, in its sole discretion and as a condition precedent to the payment
thereof, require the owner of such lost, stolen or destroyed certificate to
deliver an indemnity agreement or a bond in such sum as it may reasonably direct
as indemnity against any claim that may be made against ITI, the Surviving
Corporation, the Exchange Agent or any other party with respect to the
certificate alleged to have been lost, stolen or destroyed.

                  (c) Neither ITI nor the Surviving Corporation shall be liable
to any holder or former holders of SLC Common Stock or ITI Common Stock for any
shares of common stock (or dividends or distributions with respect thereto), or
for any cash amounts properly delivered to any public official pursuant to any
applicable abandoned property, escheat or similar law.

                  (d) No fractional interests in shares of ITI Common Stock, and
no certificates representing such fractional interests, shall be issued upon the
surrender for exchange of certificates representing SLC Common Stock. In lieu of
any fractional share, ITI shall pay to each former holder of SLC Common Stock
who otherwise would be entitled to receive a fractional interest in a share of
ITI Common Stock (after aggregating all fractional shares of ITI Common Stock
issuable to such holder), upon surrender of such holder's SLC Certificates an
amount of cash (without interest) determined by multiplying (i) the Per Share
Cash Consideration by (ii) the fractional interest to which such holder would
otherwise be entitled.

                  Section 1.9 Stock Options.

                  (a) Each holder of options to purchase ITI Common Stock ("ITI
Option") shall be given the right to elect to receive a cash payment, for up to
50% of the number of shares of ITI Common Stock covered by such options, equal
to the Per Share Cash Consideration times the number of shares covered by such
options minus the aggregate exercise price of such options in exchange for the
cancellation of such options. Any ITI Option not so exchanged will remain
outstanding pursuant to its terms and will vest to the extent provided in the
existing terms of the applicable stock option plan or any agreement evidencing
such option.

                  (b) At the Effective Time, all rights with respect to SLC
Common Stock under each option to purchase SLC Common Stock ("SLC Option") then
outstanding shall be converted into and become rights with respect to ITI Common
Stock, and ITI shall assume each such SLC Option in accordance with the
requirements of Section 424 (a) of the Code and the terms of the stock option
plan under which it was issued and the stock option agreement by which it is
evidenced. From and after the Effective Time, (i) each SLC Option assumed by ITI
may be exercised solely for shares of ITI Common Stock, (ii) the number of
shares of ITI Common Stock covered by each such SLC Option shall be equal to the
number of shares of SLC Common Stock covered by such SLC Option immediately
prior to the Effective Time multiplied


                                       6
<PAGE>



by the SLC Per Share Stock Consideration, rounded up to the nearest whole share
and (iii) the per share exercise price under each such SLC Option shall be
adjusted by dividing the per share exercise price under such SLC Option by the
SLC Per Share Stock Consideration and rounding up to the nearest cent. Each SLC
Option assumed by ITI in accordance with this Section 1.9(b) shall, in
accordance with its terms, be subject to further adjustments as appropriate to
reflect any stock split, stock dividend, reverse stock split, reclassification,
recapitalization or other similar transaction prior to the Effective Time.

                  Section 1.10 Further Assurances. If at any time after the
Effective Time the Surviving Corporation shall consider or be advised that any
deeds, bills of sale, assignments or assurances or any other acts or things are
necessary, desirable or proper (a) to vest, perfect or confirm, of record or
otherwise, in the Surviving Corporation its right, title or interest in, to or
under any of the rights, privileges, powers, franchises, properties or assets of
either of the Constituent Corporations, or (b) otherwise to carry out the
purposes of this Agreement, the Surviving Corporation and its proper officers
and directors or their designees shall be authorized to execute and deliver, in
the name and on behalf of either of the Constituent Corporations, all such
deeds, bills of sale, assignments and assurances and to do, in the name and on
behalf of either Constituent Corporation, all such other acts and things as may
be necessary, desirable or proper to vest, perfect or confirm the Surviving
Corporation's right, title or interest in, to or under any of the rights,
privileges, powers, franchises, properties or assets of such Constituent
Corporation and otherwise to carry out the purposes of this Agreement.

                  Section 1.11 Closing. The closing of the transactions
contemplated by this Agreement (the "Closing") and all actions specified in this
Agreement to occur at the Closing shall take place at the offices of Dorsey &
Whitney LLP, 220 South Sixth Street, Minneapolis, Minnesota, at 10:00 a.m.,
local time, on the second business day following the day on which the last of
the conditions set forth in Article VI shall have been fulfilled or waived (if
permissible) or at such other time and place as ITI and SLC shall agree.

                                   ARTICLE II

                      REPRESENTATIONS AND WARRANTIES OF ITI
                      -------------------------------------

                  ITI represents and warrants to SLC as follows:

                  Section 2.1 Organization, Standing and Power. ITI 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 and authority to
carry on its business as now being conducted. Each Subsidiary (as hereinafter
defined) of ITI is duly organized, validly existing and in good standing under
the laws of the jurisdiction in which it is organized and has the requisite
corporate (in the case of a subsidiary that is a corporation) or other power and
authority to carry on its business as now being conducted, except where the
failure to be so organized, existing or in good standing or to have such power
or authority would not, individually or in the aggregate, have a


                                       7
<PAGE>



Material Adverse Effect (as hereinafter defined) on ITI. ITI and each of its
Subsidiaries are duly qualified to do business, and are in good standing, in
each jurisdiction where the character of their properties owned or held under
lease or the nature of their activities makes such qualification necessary,
except where the failure to be so qualified would not, individually or in the
aggregate, have a Material Adverse Effect on ITI. For purposes of this Agreement
(a) "Material Adverse Change" or "Material Adverse Effect" means, when used with
respect to ITI or SLC, as the case may be, any event, occurrence, development,
change or effect that, individually or in the aggregate, with other events,
occurrences, developments, changes or effects, is or could reasonably be
expected (as far as can be foreseen at the time) to be materially adverse to the
business, assets, liabilities, financial condition or results of operations of
ITI and its Subsidiaries, taken as a whole, or SLC and its Subsidiaries, taken
as a whole, as the case may be; and (b) "Subsidiary" means any corporation,
partnership, limited liability company, joint venture or other legal entity of
which ITI or SLC, as the case may be (either alone or through or together with
any other Subsidiary), owns, directly or indirectly, 50% or more of the stock or
other equity interests the holders of which are generally entitled to vote for
the election of the board of directors or other governing body of such
corporation, partnership, limited liability company, joint venture or other
legal entity.

                  Section 2.2 Capital Structure. As of the date hereof, the
authorized capital stock of ITI consists solely of 30,000,000 shares of ITI
Common Stock and no shares of Preferred Stock. At the close of business on
September 28, 1999, (i) 8,438,342 shares of ITI Common Stock were issued and
outstanding, all of which were validly issued, fully paid and nonassessable and
free of preemptive rights, (ii) 956,700 shares of ITI Common Stock were held in
the treasury of ITI or by Subsidiaries of ITI, (iii) 1,713,920 shares of ITI
Common Stock were reserved for issuance pursuant to outstanding options to
purchase shares of ITI Common Stock and other benefits granted under ITI's
benefit plans, or pursuant to any plans assumed by ITI in connection with any
acquisition, business combination or similar transaction and (iv) each share of
ITI Common Stock is accompanied by a "Right" as defined in the Rights Agreement
dated as of November 27, 1996 by and between ITI and Norwest Bank Minnesota,
National Association as rights agent (the "Shareholder Rights Plan"). As of the
date of this Agreement, except as set forth above no shares of capital stock or
other voting securities of ITI were issued, reserved for issuance or
outstanding. All of the shares of ITI Common Stock issuable in exchange for SLC
Common Stock at the Effective Time in accordance with this Agreement will be,
when so issued, duly authorized, validly issued, fully paid and nonassessable
and free of preemptive rights. As of the date of this Agreement, except (i) for
this Agreement, (ii) as set forth above, or (iii) as set forth in Section 2.2 of
the letter dated the date hereof and delivered on the date hereof by ITI to SLC,
which letter relates to this Agreement and is designated therein as the ITI
Letter (the "ITI Letter"), there are no options, warrants, calls, rights,
agreements or other commitments to which ITI or any of its Subsidiaries is a
party or by which any of them is bound obligating ITI or any of its Subsidiaries
to issue, deliver or sell, or cause to be issued, delivered or sold, additional
shares of capital stock of ITI or any of its Subsidiaries or obligating ITI or
any of its Subsidiaries to grant, extend or enter into any such option, warrant,
call, right, agreement or other commitment. Except as set forth in Section 2.2
of the ITI Letter, neither ITI nor any of its Subsidiaries is


                                       8
<PAGE>



obligated to pay for or repurchase any shares of capital stock of ITI or any of
its Subsidiaries. There are no outstanding ITI securities that are convertible
into or exchangeable for any shares of capital stock or other securities of ITI
or its Subsidiaries. Each outstanding share of capital stock of each Subsidiary
of ITI is duly authorized, validly issued, fully paid and nonassessable and,
except as disclosed in Section 2.2 of the ITI Letter, each such share is owned
by ITI or another Subsidiary of ITI, free and clear of all security interests,
liens, claims, pledges, options, rights of first refusal, agreements,
limitations on voting rights, charges and other encumbrances of any nature
whatsoever. Except as set forth in Section 2.2 of the ITI Letter, no holder of
ITI Common Stock, or any option, warrant or other security exchangeable or
convertible into ITI Common Stock, has any rights, contingent or otherwise, to
require ITI to register such securities under the Securities Act (as hereinafter
defined). Except as set forth above, ITI does not have any outstanding bonds,
debentures, notes or other obligations the holders of which have the right to
vote (or convertible into, exchangeable for or exercisable for securities having
the right to vote) with the stockholders of ITI on any matter. All of ITI's
Subsidiaries are wholly owned, directly or indirectly, by ITI and are listed in
Section 2.2 of the ITI Letter.

                  Section 2.3 Authority. On or prior to the date of this
Agreement, the Board of Directors of ITI , at a meeting duly called and held at
which a quorum was present throughout, has by the requisite vote of the
directors, declared the Merger to be advisable and fair to and in the best
interest of ITI and its stockholders, has approved and adopted this Agreement in
accordance with the DGCL and has resolved to recommend the approval by ITI's
stockholders of the Merger and this Agreement and no such declaration, approval,
adoption or recommendation has been changed, withdrawn or revoked. ITI has all
requisite corporate power and authority to enter into this Agreement, and,
subject to approval by the stockholders of ITI of the Merger, to consummate the
transactions contemplated hereby. The execution and delivery of this Agreement
by ITI and the consummation by ITI of the transactions contemplated hereby have
been duly authorized by all necessary corporate action on the part of ITI,
subject to (x) approval by the stockholders of ITI of the Merger and (y) the
filing of the Certificate of Merger. This Agreement has been duly executed and
delivered by ITI, and (assuming the valid authorization, execution and delivery
of this Agreement by SLC and the validity and binding effect hereof on SLC) this
Agreement constitutes the valid and binding obligation of ITI enforceable
against ITI in accordance with its terms.

                  Section 2.4 Consents and Approvals; No Violation. Assuming
that all consents, approvals, authorizations and other actions described in this
Section 2.4 have been obtained and all filings and obligations described in this
Section 2.4 have been made, and except as set forth in Section 2.4 of the ITI
Letter, the execution and delivery of this Agreement do not, and the
consummation of the transactions contemplated hereby and compliance with the
provisions hereof will not, result in any violation of, or default (with or
without notice or lapse of time, or both) under, or give to others a right of
termination, cancellation or acceleration of any obligation or the loss of a
material benefit under, or result in the creation of any lien, security
interest, charge or encumbrance upon any of the properties or assets of ITI or
any of its Subsidiaries under, any provision of (i) the Certificate of
Incorporation or Bylaws of ITI, (ii) any


                                       9
<PAGE>



provision of the comparable charter or organization documents of any of ITI's
Subsidiaries, (iii) any loan or credit agreement, note, bond, mortgage,
indenture, lease or other agreement, instrument, permit, concession, franchise
or license applicable to ITI or any of its Subsidiaries or (iv) any judgment,
order, injunction, decree, statute, law, ordinance, rule or regulation
applicable to ITI or any of its Subsidiaries or any of their respective
properties or assets, other than, in the case of clauses (iii) or (iv), any such
violations, defaults, rights, liens, security interests, charges or encumbrances
that, individually or in the aggregate, would not have a Material Adverse Effect
on ITI, materially impair the ability of ITI to perform its obligations
hereunder or prevent the consummation of any of the transactions contemplated
hereby. Except as set forth in Section 2.4 of the ITI Letter, no filing or
registration with review by, or authorization, consent or approval of, any third
party, including any domestic (federal, state or local), foreign or
supranational court, commission, governmental body, regulatory agency, authority
or tribunal (a "Governmental Entity") is required by or with respect to ITI or
any of its Subsidiaries in connection with the execution and delivery of this
Agreement by ITI or is necessary for the consummation of the Merger and the
other transactions contemplated by this Agreement and compliance with the
provisions hereof, except for (i) in connection, or in compliance, with the
provisions of the Hart- Scott-Rodino Antitrust Improvements Act of 1976, as
amended (the "HSR Act"), the Securities Act of 1933, as amended (together with
the rules and regulation promulgated thereunder the "Securities Act"), and the
Securities Exchange Act of 1934, as amended (together with the rules and
regulations promulgated thereunder, the "Exchange Act"), (ii) the filing of the
Certificate of Merger with the Secretary of State of the State of Delaware and
appropriate documents with the relevant authorities of other states in which ITI
is qualified to do business, (iii) applicable requirements, if any, of state
securities or "blue sky" laws ("Blue Sky Laws"), (iv) as may be required under
foreign laws and (v) such other consents, orders, authorizations, registrations,
declarations and filings the failure of which to be obtained or made would not,
individually or in the aggregate, have a Material Adverse Effect on ITI,
materially impair the ability of ITI to perform its obligations hereunder or
prevent the consummation of any of the transactions contemplated hereby.

                  Section 2.5 SEC Documents and Other Reports; Financial
Matters.

                  (a) ITI has timely filed with the SEC all forms, reports,
schedules, statements and other documents required to be filed by it under the
Exchange Act or the Securities Act since January 1, 1995 (the "ITI SEC
Documents"). As of their respective dates (and in the case of registration
statements and proxy statements, on the dates of effectiveness and the dates of
mailing, respectively), the ITI SEC Documents complied in all material respects
with the requirements of the Securities Act or the Exchange Act, as the case may
be, and, at the respective times they were filed (and in the case of
registration statements and proxy statements, on the dates of effectiveness and
the dates of mailing, respectively), none of the ITI SEC Documents contained any
untrue statement of a material fact or omitted to state a material fact required
to be stated therein or necessary to make the statements therein, in light of
the circumstances under which they were made, not misleading. The consolidated
financial statements (including, in each case, any notes thereto) of ITI
included in the ITI SEC Documents (the "ITI Financial


                                       10
<PAGE>



Statements") at the respective times they were filed (and in the case of
registration statements and proxy statements, on the dates of effectiveness and
the dates of mailing, respectively) complied as to form in all material respects
with applicable accounting requirements and the published rules and regulations
of the SEC with respect thereto, were prepared in accordance with generally
accepted accounting principles (except, in the case of the unaudited statements,
as permitted by Form 10-Q of the SEC) applied on a consistent basis during the
periods involved (except as may be indicated therein or in the notes thereto)
and fairly presented in all material respects the consolidated financial
position of ITI and its consolidated Subsidiaries as at the respective dates
thereof and the consolidated results of their operations and their consolidated
cash flows for the periods then ended (subject, in the case of unaudited
statements, to normal year-end audit adjustments and to any other adjustments
described therein which were not or are not expected to be material in amount).
Except as set forth in Section 2.5 of the ITI Letter, ITI has not, since
December 31, 1998, made any change in the accounting practices or policies
applied in the preparation of financial statements.

                  (b) The minute books of ITI and its Subsidiaries, all of which
have been made available to SLC, contain records of all meetings held of, and
corporate action taken by, the stockholders and the Board of Directors of ITI
and its Subsidiaries, which are accurate in all material respects, and no
meeting of any such stockholders or Board of Directors has been held for which
minutes have not been prepared and are not contained in such minute books.

                  (c) ITI and its Subsidiaries do not have any liabilities of
any nature, whether known or unknown, absolute, accrued, contingent or otherwise
and whether due or to become due that, individually or in the aggregate, have a
Material Adverse Effect on ITI, except (i) as and to the extent set forth on the
most recent balance sheet included in the ITI SEC Documents, (ii) for
liabilities or obligations incurred since the date of the balance sheet referred
to in clause (i) in the ordinary course of business or (iii) as set forth in
Section 2.5 of the ITI Letter. The term "liabilities" is not intended to include
contractual obligations (other than those in default or those that would be in
default upon the giving of notice, the passage of time or both) other than those
customarily reflected on the face of a balance sheet.

                  Section 2.6 Proxy Statement. None of the information to be
supplied by or on behalf of ITI for inclusion or incorporation by reference in
the definitive proxy statement (the "Proxy Statement") relating to the ITI
Stockholder Meeting (as defined in Section 5.1) will, at the time of the mailing
of the Proxy Statement, at the time of the ITI Stockholder Meeting or at the
Effective Time, contain any untrue statement of a material fact or omit to state
any material fact required to be stated therein or necessary in order to make
the statements therein, in light of the circumstances under which they are made,
not misleading. The Proxy Statement will comply as to form in all material
respects with the provisions of the Exchange Act.

                  (p) Neither ITI nor any of its Subsidiaries has made any
         material election with respect to Taxes nor has ITI or any of its
         Subsidiaries entered into an agreement, arrangement or settlement with
         respect to material Taxes with any taxing authority or other person;
         and

                  (q) ITI has not entered into any commitment (written or oral,
         contingent or otherwise) to do any of the foregoing.

                  The phrase "consistent with past practice" wherever used is
intended as a limitation only when current practices can be meaningfully
compared to past practices. In this Section 2.7 "ITI" refers to ITI and/or its
Subsidiaries.

                  Section 2.8 Permits and Compliance. Each of ITI and its
Subsidiaries is in possession of all franchises, grants, authorizations,
licenses, permits, charters, easements, variances, exceptions, consents,
certificates, approvals and orders of any Governmental Entity


                                       13
<PAGE>



necessary for ITI or any of its Subsidiaries to own, lease and operate its
properties or to carry on its business as it is now being conducted (the "ITI
Permits"), except where the failure to have any of the ITI Permits would not,
individually or in the aggregate, have a Material Adverse Effect on ITI, and, as
of the date of this Agreement, no suspension or cancellation of any of the ITI
Permits is pending or, to the Knowledge of ITI (as hereinafter defined),
threatened, except where the suspension or cancellation of any of the ITI
Permits would not, individually or in the aggregate, have a Material Adverse
Effect on ITI. Neither ITI nor any of its Subsidiaries is in violation of (A)
its charter, by-laws or other organizational documents, (B) any applicable law,
ordinance, administrative or governmental rule or regulation or (C) any order,
decree or judgment of any Governmental Entity having jurisdiction over ITI or
any of its Subsidiaries, except, in the case of clauses (A), (B) and (C), for
any violations that, individually or in the aggregate, would not have a Material
Adverse Effect on ITI. Except as disclosed in Section 2.8 of the ITI Letter, as
of the date hereof there is no contract or agreement that is material to the
business, assets, liabilities, financial condition or results of operations of
ITI and its Subsidiaries, taken as a whole. Except as set forth in Section 2.8
of the ITI Letter, no event of default or event that, but for the giving of
notice or the lapse of time or both, would constitute an event of default exists
or, upon the consummation by ITI of the transactions contemplated by this
Agreement, will exist under any indenture, mortgage, loan agreement, note or
other agreement or instrument for borrowed money, any guarantee of any agreement
or instrument for borrowed money or any lease, contractual license or other
agreement or instrument to which ITI or any of its Subsidiaries is a party or by
which ITI or any such Subsidiary is bound or to which any of the properties,
assets or operations of ITI or any such Subsidiary is subject, other than any
defaults that, individually or in the aggregate, would not have a Material
Adverse Effect on ITI. ITI has no reason to believe that all material
agreements, guarantees and commitments (each a "Contract") to which ITI or any
Subsidiary is a party or by which ITI or any Subsidiary is bound are not valid
and binding obligations of ITI or such Subsidiary and each other party thereto
except such Contracts which if not so valid and binding would not, individually
or in the aggregate, have a Material Adverse Effect on ITI. ITI has no reason to
believe that any other party to a Contract is in violation of or in default
under such Contract except such violations or defaults which, individually or in
the aggregate, would not have a Material Adverse Effect on ITI. Neither ITI nor
any of its Subsidiaries is a party to or bound by any Contract that, after the
Effective Time, would interfere with the conduct of the Surviving Corporation's
business, except for such interference that would not have a Material Adverse
Effect on the Surviving Corporation. For purposes of this Agreement, "Knowledge
of ITI" (and similar phrases) means the actual knowledge, after reasonable
inquiry, of the individuals identified in Section 2.8 of the ITI Letter.

                  Section 2.9 Tax Matters. Except as otherwise set forth in
Section 2.9 of the ITI Letter, (i) ITI and each of its Subsidiaries have timely
filed all federal, and all material state, local, foreign and provincial, Tax
Returns (as hereinafter defined) required to have been filed or appropriate
extensions therefor have been properly obtained, and such Tax Returns are
correct and complete, except to the extent that any failure to so file or any
failure to be correct and complete would not, individually or in the aggregate,
have a Material Adverse Effect on ITI; (ii) all Taxes (as hereinafter defined)
shown to be due on such Tax Returns have been timely paid or


                                       14
<PAGE>



extensions for payment have been properly obtained, or such Taxes are being
timely and properly contested (such contested Taxes being set forth in Section
2.9 of the ITI Letter), (iii) ITI and each of its Subsidiaries have complied in
all material respects with all rules and regulations relating to the withholding
of Taxes except to the extent that any failure to comply with such rules and
regulations would not, individually or in the aggregate, have a Material Adverse
Effect on ITI; (iv) neither ITI nor any of its Subsidiaries has waived any
statute of limitations in respect of its Taxes; (v) no Tax Return referred to in
clause (i) that reflected material Taxes is currently being examined by the
appropriate taxing authority (all such federal Tax Returns that are closed being
listed in Section 2.9 of the ITI Letter); (vi) no issues have been raised by the
relevant taxing authority in connection with the examination of the Tax Returns
referred to in clause (i) that are currently pending, asserted or threatened;
(vii) neither ITI nor any of its Subsidiaries is a party to a closing agreement,
or the subject of a private ruling, concerning Taxes with any taxing authority;
(viii) except as provided under Treas. Reg. Section 1.1502-6 (or any similar
provision of state, local or foreign law), neither ITI nor any of its
Subsidiaries has any liability or obligation to pay Taxes of another person;
(ix) neither ITI nor any of its Subsidiaries has made any payment, is obligated
to make any payment, or is a party to any agreement (including this Agreement),
that could obligate it to make any payment that will not be deductible under
Section 280G of the Code; and (x) all deficiencies asserted or assessments made
as a result of any examination of Tax Returns referred to in clause (i) by any
taxing authority have been paid in full or are being timely and properly
contested (such contested items being set forth in Section 2.9 of the ITI
Letter). All Taxes of ITI and its Subsidiaries which will be due and payable,
whether now or hereafter, for any period ending on, ending on and including or
ending prior to the Effective Time shall have been paid by or on behalf of ITI
and its Subsidiaries or shall be reflected, in a manner consistent with past
practice, on ITI's books as an accrued Tax liability, either current or
deferred. For purposes of this Agreement: (i) "Taxes" means any federal, state,
local, foreign or provincial income, gross receipts, property, sales, use,
license, excise, franchise, employment, payroll, withholding, alternative or
added minimum, ad valorem, value-added, transfer or excise tax, or other tax,
custom, duty, governmental fee or other like assessment or charge of any kind
whatsoever, together with any interest or penalty imposed by any Governmental
Entity, and (ii) "Tax Return" means any return, report or similar statement
(including the attached schedules) required to be filed with respect to any Tax,
including, without limitation, any information return, claim for refund, amended
return or declaration of estimated Tax.

                  Section 2.10 Actions and Proceedings. Except as set forth in
Section 2.10 of the ITI Letter, there are no, and since January 1, 1999, there
have been no, outstanding orders, judgments, injunctions, awards or decrees of
any Governmental Entity against or involving ITI or any of its Subsidiaries, or
against or involving any of the present or former directors, officers,
employees, consultants, agents or stockholders of ITI or any of its
Subsidiaries, as such, any of its or their properties, assets or business or any
ITI Plan (as hereinafter defined) that, individually or in the aggregate, would
have a Material Adverse Effect on ITI or materially impair the ability of ITI or
its Subsidiaries to perform its obligations hereunder. Except as set forth in
Section 2.10 of the ITI Letter, there are no actions, suits or claims or legal,
administrative or arbitrative proceedings or investigations pending or, to the
Knowledge of ITI, threatened against or


                                       15
<PAGE>



involving ITI or any of its Subsidiaries or any of its or their present or
former directors, officers, employees, consultants, agents or stockholders, as
such, or any of its or their properties, assets or business or any ITI Plan
that, individually or in the aggregate, would have a Material Adverse Effect on
ITI or materially impair the ability of ITI or its Subsidiaries to perform its
obligations hereunder. There are no actions, suits, labor disputes or other
litigation, legal or administrative proceedings or governmental investigations
pending or, to the Knowledge of ITI, threatened against or affecting ITI or any
of its Subsidiaries or any of its or their present or former officers,
directors, employees, consultants, agents or stockholders, as such, or any of
its or their properties, assets or business relating to the transactions
contemplated by this Agreement that would have a Material Adverse Effect on the
Surviving Corporation, after giving effect to available insurance coverage.

                  Section 2.11 Certain Agreements. Except as otherwise set forth
in Section 2.11 of the ITI Letter, neither ITI nor any of its Subsidiaries is a
party to any material oral or written agreement or plan, including any
employment agreement, severance agreement, stock option plan, stock appreciation
rights plan, restricted stock plan or stock purchase plan, any of the benefits
of which will be increased, or the vesting of the benefits of which will be
accelerated, by the occurrence of any of the transactions contemplated by this
Agreement or the value of any of the benefits of which will be calculated on the
basis of any of the transactions contemplated by this Agreement.

                  Section 2.12 ERISA.

                  (a) Each material ITI Plan (as hereinafter defined) is listed
in Section 2.12 of the ITI Letter. Except as would not have a Material Adverse
Effect on ITI, each ITI Plan complies in all respects with the Employee
Retirement Income Security Act of 1974, as amended ("ERISA"), the Code and all
other applicable statutes and governmental rules and regulations, and (i) no
"reportable event" (within the meaning of Section 4043 of ERISA) has occurred
with respect to any ITI Plan that is likely to have individually or in the
aggregate, a Material Adverse Effect on ITI and (ii) ITI has not withdrawn from
any ITI Plan or ITI Multiemployer Plan (as hereinafter defined) or instituted,
or is currently considering taking, any action to do so. Except as would not
have a Material Adverse Effect on ITI, no ITI Plan, nor any trust created
thereunder, has incurred any "accumulated funding deficiency" (as defined in
Section 302 of ERISA), whether or not waived. Neither ITI nor any ERISA
Affiliate of ITI maintains a plan subject to Title IV of ERISA. Neither ITI nor
any ERISA Affiliate has ever contributed to, or been required to contribute to
any "multiemployer plan" (within the meaning of Section 3(37) of ERISA). For
this purpose, "ERISA Affiliate" means any entity which is under common control
with or which would be considered a single employer with ITI pursuant to Section
414(b), (c), (m) or (o) of the Code. Except for the Subsidiaries, there are no
ERISA Affiliates of ITI.

                  (b) With respect to the ITI Plans, no event has occurred and,
to the Knowledge of ITI, there exists no condition or set of circumstances in
connection with which ITI or any ITI Plan fiduciary could be subject to any
liability under the terms of such ITI Plans, ERISA, the


                                       16
<PAGE>



Code or any other applicable law, other than liabilities for benefits payable in
the normal course, which would have a Material Adverse Effect on ITI. All ITI
Plans that are intended to be qualified under Section 401(a) of the Code have
been determined by the IRS to be so qualified, or a timely application for such
determination is now pending or a request for such a determination filed within
the remedial amendment period of Section 401(b) of the Code is pending, and ITI
is not aware of any reason why any such ITI Plan is not so qualified in
operation. ITI has not been notified by any ITI Multiemployer Plan that such ITI
Multiemployer Plan is currently in reorganization or insolvency under and within
the meaning of Section 4241 or 4245 of ERISA or that such ITI Multiemployer Plan
intends to terminate or has been terminated under Section 4041A of ERISA. Except
as disclosed in Section 2.12(b) of ITI Letter, ITI does not have any liability
or obligation under any welfare plan to provide benefits after termination of
employment to any employee or dependent other than as required by Section 4980B
of the Code.

                  (c) As used herein, (i) "ITI Plan" means a "pension plan" (as
defined in Section 3(2) of ERISA (other than a ITI Multiemployer Plan)), a
"welfare plan" (as defined in Section 3(1) of ERISA), or any bonus, profit
sharing, deferred compensation, incentive compensation, stock ownership, stock
purchase, stock option, phantom stock, holiday pay, vacation, severance, death
benefit, sick leave, fringe benefit, personnel policy, insurance or other plan,
arrangement or understanding, in each case established or maintained by ITI or
any of its Subsidiaries as to which ITI or any of its Subsidiaries has
contributed or otherwise may have any liability and (ii) "ITI Multiemployer
Plan" means a "multiemployer plan" (as defined in Section 4001(a)(3) of ERISA)
to which ITI is or has been obligated to contribute or otherwise may have any
liability.

                  Section 2.13 Compliance with Worker Safety and Environmental
Laws. The properties, assets and operations of ITI and its Subsidiaries are in
compliance with all applicable federal, state, local and foreign laws, rules and
regulations, orders, decrees, judgments, permits and licenses relating to public
and worker health and safety (collectively, "Worker Safety Laws") and the
protection and clean-up of the environment and activities or conditions related
thereto, including, without limitation, those relating to the generation,
handling, disposal, transportation or release of hazardous materials
(collectively, "Environmental Laws"), except for any violations that,
individually or in the aggregate, would not have a Material Adverse Effect on
ITI. No hazardous materials have been released, spilled, leaked, discharged,
disposed of, pumped, poured, emitted, emptied, injected, leached, dumped or
allowed to escape ("Releases") by any person at any property now owned, operated
or leased by ITI or its Subsidiaries or by ITI or a Subsidiary at any property
formerly owned, operated or leased by ITI or its Subsidiaries, except for such
Releases that individually and in the aggregate would not have a Material
Adverse Effect on ITI. Neither ITI nor any Subsidiary have received any request
for information, notice of claim, demand or notification that it is or may be
potentially responsible with respect to any investigation or clean-up of any
threatened or actual Release. Except as set forth in Section 2.13 of the ITI
Letter and heretofore provided to SLC, within the past five years, there have
been no environmental inspections, studies, audits, tests, reviews or other
analyses conducted by a third


                                       17
<PAGE>



party environmental consultant or engineer in relation to any property or
business now or previously owned, operated or leased by ITI or its Subsidiaries.
With respect to such properties, assets and operations, including any previously
owned, leased or operated properties, assets or operations, there are no events,
conditions, circumstances, activities, practices, incidents, actions or plans of
ITI or any of its Subsidiaries that may interfere with or prevent compliance or
continued compliance with applicable Worker Safety Laws and Environmental Laws,
other than any such interference or prevention as would not, individually or in
the aggregate with any such other interference or prevention, have a Material
Adverse Effect on ITI.

                  Section 2.14 Labor Matters. Except as otherwise set forth in
Section 2.14 of the ITI Letter, neither ITI nor any of its Subsidiaries is a
party to any collective bargaining agreement or labor contract. Neither ITI nor
any of its Subsidiaries has engaged in any unfair labor practice with respect to
any persons employed by or otherwise performing services primarily for ITI or
any of its Subsidiaries (the "ITI Business Personnel"), and there is no unfair
labor practice complaint or grievance against ITI or any of its Subsidiaries by
the National Labor Relations Board or any comparable state agency pending or
threatened in writing with respect to ITI Business Personnel, except where such
unfair labor practice, complaint or grievance would not have a Material Adverse
Effect on ITI. There is no labor strike, dispute, slowdown or stoppage pending
or, to the Knowledge of ITI, threatened against or affecting ITI or any of its
Subsidiaries which may interfere with the respective business activities of ITI
or any of its Subsidiaries, except where such dispute, strike or work stoppage
would not have a Material Adverse Effect on ITI.

                  Section 2.15 Intellectual Property.

                  (a) For the purposes of this Agreement, the following terms

as a whole; or (ii) is material to the operation of ITI and its Subsidiaries,
taken as a whole, including the design, manufacture and use of the products

including, without limitation, the design, development, manufacture and sale of
all products and/or technology currently manufactured, licensed or sold by ITI
or any Subsidiary or under development by ITI or any Subsidiary.

Subsidiaries listed in Section 2.15(b) of the ITI Letter are valid and
subsisting and in full force, all necessary registration and renewal fees in

complied in all material respects with all applicable disclosure requirements
and neither ITI, any Subsidiary nor any named inventor or assignee has committed
any fraudulent act in the application for or maintenance of any Intellectual
Property of ITI. All Intellectual Property of ITI listed in Section 2.15(b) of
the ITI Letter that is within the meaning of (i)-(v) above is specifically

                                   ARTICLE III

                      REPRESENTATIONS AND WARRANTIES OF SLC
                      -------------------------------------

                  SLC represents and warrants to ITI as follows:

                  Section 3.1 Organization, Standing and Power. 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 and authority to
carry on its business as now being conducted. Each Subsidiary of SLC is duly
organized, validly existing and in good standing under the laws of the
jurisdiction in which it is organized and has the requisite corporate (in the
case of a Subsidiary that is a corporation) or other power and authority to
carry on its business as now being conducted, except where the failure to be so
organized, existing or in good standing or to have such power or authority would
not, individually or in the aggregate, have a Material Adverse Effect on SLC.
SLC and each of its Subsidiaries are duly qualified to do business, and are in
good standing, in each jurisdiction where the character of their properties
owned or held under lease or the nature of their activities makes such
qualification necessary, except where the failure to be so qualified would not,
individually or in the aggregate, have a Material Adverse Effect on SLC.

                  Section 3.2 Capital Structure. As of the date hereof, the
authorized capital stock of SLC consists solely of 2,000,000 shares of SLC
Common Stock, $.005 par value. At the close of business on September 22, 1999,
(i) 1,000,000 shares of SLC Common Stock were issued and outstanding, all of
which were validly issued, fully paid and nonassessable and free of preemptive
rights, (ii) no shares of SLC Common Stock were held in the treasury of SLC or
by Subsidiaries of SLC and (iii) 50,000 shares of SLC Common Stock were reserved
for issuance pursuant to outstanding options to purchase shares of SLC Common
Stock and other benefits granted under SLC's benefit plans, or pursuant to any
plans assumed by SLC in connection with any acquisition, business combination or
similar transaction. As of the date of this Agreement,


                                       22
<PAGE>



except as set forth above, no shares of capital stock or other voting securities
of SLC were issued, reserved for issuance or outstanding. As of the date of this
Agreement, except (i) for this Agreement, (ii) as set forth above or (iii) as
set forth in Section 3.2 of the letter dated the date hereof and delivered on
the date hereof by SLC to ITI, which letter relates to this Agreement and is
designated therein as the SLC Letter (the "SLC Letter"), there are no options,
warrants, calls, rights, agreements or other commitments to which SLC or any of
its Subsidiaries is a party or by which any of them is bound obligating SLC or
any of its Subsidiaries to issue, deliver or sell, or cause to be issued,
delivered or sold, additional shares of capital stock of SLC or any of its
Subsidiaries or obligating SLC or any of its Subsidiaries to grant, extend or
enter into any such option, warrant, call, right, agreement or other commitment.
Except as set forth in Section 3.2 of the SLC Letter, neither SLC nor any of its
Subsidiaries is obligated to pay for or repurchase any shares of capital stock
of SLC or any of its Subsidiaries. There are no outstanding SLC securities that
are convertible into or exchangeable for any shares of capital stock or other
securities of SLC or its Subsidiaries. Each outstanding share of capital stock
of each Subsidiary of SLC is duly authorized, validly issued, fully paid and
nonassessable and, except as disclosed in Section 3.2 of the SLC Letter, each
such share is owned by SLC or another Subsidiary of SLC, free and clear of all
security interests, liens, claims, pledges, options, rights of first refusal,
agreements, limitations on voting rights, charges and other encumbrances of any
nature whatsoever. Except as set forth above, SLC does not have any outstanding
bonds, debentures, notes or other obligations the holders of which have the
right to vote (or convertible into, exchangeable for or exercisable for
securities having the right to vote) with the stockholders of SLC on any matter.
Except as otherwise set forth in Section 3.2 of the SLC Letter, all of SLC's
Subsidiaries are wholly owned, directly or indirectly, by SLC and are listed in
Section 3.2 of the SLC Letter.

                  Section 3.3 Authority. On or prior to the date of this
Agreement, the Board of Directors of SLC, at a meeting duly called and held at
which a quorum was present throughout, has by the requisite vote of the
directors, declared the Merger to be advisable and fair to and in the best
interest of SLC and its stockholders and has approved this Agreement in
accordance with the DGCL. The stockholder of SLC has approved this Agreement in
accordance with the DGCL, and this Agreement, and such approval, has not been
changed, withdrawn or revoked. SLC has all requisite corporate power and
authority to enter into this Agreement and to consummate the transactions
contemplated hereby. The execution and delivery of this Agreement by SLC and the
consummation by SLC of the transactions contemplated hereby have been duly
authorized by all necessary corporate action on the part of SLC, subject to the
filing of the Certificate of Merger. This Agreement has been duly executed and
delivered by SLC and (assuming the valid authorization, execution and delivery
of this Agreement by ITI and the validity and binding effect hereof on ITI)
constitutes the valid and binding obligation of SLC enforceable against SLC in
accordance with its terms.

                  Section 3.4 Consents and Approvals; No Violation. Assuming
that all consents, approvals, authorizations and other actions described in this
Section 3.4 have been obtained and all filings and obligations described in this
Section 3.4 have been made, except as set forth in Section 3.4 of SLC Letter,
the execution and delivery of this Agreement do not, and


                                       23
<PAGE>



the consummation of the transactions contemplated hereby and compliance with the
provisions hereof will not, result in any violation of, or default (with or
without notice or lapse of time, or both) under, or give to others a right of
termination, cancellation or acceleration of any obligation or the loss of a
material benefit under, or result in the creation of any lien, security
interest, charge or encumbrance upon any of the properties or assets of SLC or
any of its Subsidiaries under, any provision of (i) the Certificate of
Incorporation or Bylaws of SLC, (ii) any provision of the comparable charter or
organization documents of any of SLC's Subsidiaries, (iii) any loan or credit
agreement, note, bond, mortgage, indenture, lease or other agreement,
instrument, permit, concession, franchise or license applicable to SLC or any of
its Subsidiaries or (iv) any judgment, order, injunction, decree, statute, law,
ordinance, rule or regulation applicable to SLC or any of its Subsidiaries or
any of their respective properties or assets, other than, in the case of clauses
(iii) or (iv), any such violations, defaults, rights, liens, security interests,
charges or encumbrances that, individually or in the aggregate, would not have a
Material Adverse Effect on SLC, materially impair the ability of SLC to perform
its obligations hereunder or prevent the consummation of any of the transactions
contemplated hereby. Except as set forth in Section 3.4 of the SLC Letter, no
filing or registration with, review by or authorization, consent or approval of,
any third party, including any Governmental Entity is required by or with
respect to SLC or any of its Subsidiaries in connection with the execution and
delivery of this Agreement by SLC or is necessary for the consummation of the

of Blue Sky Laws, (iv) as may be required under foreign laws and (v) such other
consents, orders, authorizations, registrations, declarations and filings the
failure of which to be obtained or made would not, individually or in the
aggregate, have a Material Adverse Effect on SLC, materially impair the ability
of SLC to perform its obligations hereunder or prevent the consummation of any
of the transactions contemplated hereby.

                  (a) SLC has furnished ITI with copies of (i) the audited

and the Board of Directors of SLC and its Subsidiaries, which are accurate in
all material respects, and no meeting of any such stockholders or Board of
Directors has been held for which minutes have not been prepared and are not

the Proxy Statement will, at the time of the mailing of the Proxy Statement, at
the time of the ITI Stockholder Meeting or at the Effective Time, contain any
untrue statement of a material fact or omit to state any material fact required

SLC. Except as disclosed in Section 3.8 of SLC Letter, as of the date hereof
there is no contract or agreement that is material to the business, assets,
liabilities, condition or results of operations of SLC and its Subsidiaries,
taken as a whole. Except as disclosed in Section 3.8 of SLC Letter, no event of
default or event that, but for the giving of notice or the lapse of time or
both, would constitute an event of default exists or, upon the consummation by
SLC of the transactions contemplated by this Agreement, will exist under any
indenture, mortgage, loan agreement, note or other agreement or instrument for
borrowed money, any guarantee of any agreement or instrument for borrowed money
or any lease, contractual license or other agreement or instrument to which SLC
or any of its Subsidiaries is a party or by which SLC or any such Subsidiary is
bound or to which any of the properties, assets or operations of SLC or any such
Subsidiary is subject, other than any defaults that, individually or in the
aggregate, would not have a Material Adverse Effect on SLC. SLC has no reason to
believe that all Contracts to which SLC or any Subsidiary is a party or by which
SLC or any Subsidiary is bound are not valid and binding obligations of SLC or
such Subsidiary and each other party thereto except such Contracts which if not
so valid and binding would not, individually or in the aggregate, have a
Material Adverse Effect on SLC. SLC has no reason to believe that any other
party to a Contract is in violation of or in default under such Contract except
such violations or defaults which, individually or in the aggregate, would not
have a Material Adverse Effect on SLC. Neither SLC nor any of its Subsidiaries
is a party to or bound by any Contract that, after the Effective Time, would
interfere with the conduct of the Surviving Corporation's business, except for
such interference that would not have a Material Adverse Effect on the Surviving
Corporation. For purposes of this Agreement, "Knowledge of SLC" (and similar
phrases) means the actual knowledge, after reasonable inquiry, of the
individuals identified on Section 3.8 of SLC Letter.

accrued Tax liability, either current or deferred.

                  Section 3.12 ERISA.

                  (a) Each material SLC Plan (as hereinafter defined) is listed
in Section 3.12(a) of SLC Letter. Except as would not have a Material Adverse
Effect on SLC, each SLC Plan (other than non-U.S. SLC Plans) complies in all
respects with ERISA, the Code and all other applicable statutes and governmental
rules and regulations, and (i) no "reportable event" (within the meaning of
Section 4043 of ERISA) has occurred with respect to any SLC Plan that is likely
to have individually or in the aggregate, a Material Adverse Effect on SLC, (ii)
SLC has not withdrawn from any SLC Multiemployer Plan (as hereinafter defined)
or instituted, or is currently considering taking, any action to do so, and
(iii) no action has been taken, or is currently being considered, to terminate
any SLC Plan subject to Title IV of ERISA. No SLC Plan, nor any trust created
thereunder, has incurred any "accumulated funding deficiency" (as defined in
Section 302 of ERISA), whether or not waived.

                  (b) Except as listed in Section 3.12(b) of SLC Letter, with
respect to SLC Plans, no event has occurred and, to the Knowledge of SLC, there
exists no condition or set of circumstances in connection with which SLC or any
SLC Plan fiduciary could be subject to any liability under the terms of such SLC
Plans, ERISA, the Code or any other applicable law, other than liabilities for
benefits payable in the normal course, which would have a Material Adverse
Effect on SLC. All SLC Plans that are intended to be qualified under Section
401(a) of the Code have been determined by the IRS to be so qualified, or a
timely application for such determination is now pending or a request for such a
determination filed within the remedial amendment period of Section 401(b) of
the Code is pending, and SLC is not aware of any reason why any such SLC Plan is
not so qualified in operation. SLC has not been notified by any SLC
Multiemployer Plan that such SLC Multiemployer Plan is currently in
reorganization or insolvency under and within the meaning of Section 4241 or
4245 of ERISA or that such SLC Multiemployer Plan intends to terminate or has
been terminated under Section 4041A of ERISA. Except as disclosed in Section
3.12(b) of SLC Letter, SLC does not have any liability or obligation under any
welfare plan to provide benefits after termination of employment to any employee
or dependent other than as required by Section 4980B of the Code.

defined in Section 3(2) of ERISA (other than a SLC Multiemployer Plan)), a
"welfare plan" (as defined in Section 3(1) of ERISA), or any bonus, profit
sharing, deferred compensation, incentive compensation, stock ownership, stock
purchase, stock option, phantom stock, holiday pay, vacation, severance, death
benefit, sick leave, fringe benefit, personnel policy, insurance or other plan,
arrangement or understanding, in each case established or maintained by SLC or
any of its


                                       30
<PAGE>



Subsidiaries or, as to which SLC or any of its Subsidiaries has contributed or
otherwise may have any liability, and (ii) "SLC Multiemployer Plan" means a
"multiemployer plan" (as defined in Section 4001(a)(3) of ERISA) to which SLC is
or has been obligated to contribute or otherwise may have any liability.

                  (d) Item 3.12(d) of SLC Letter contains a list of all (i)
severance and employment agreements with executive officers of SLC, (ii)
severance programs and policies of SLC with or relating to its executive
officers and (iii) plans, programs, agreements and other arrangements of SLC
with or relating to its executive officers containing change of control or
similar provisions.

                  (e) No entity which is under common control with or which
would be considered a single employer with SLC pursuant to Section 414(b), (c),
(m) or (o) of the Code (a "SLC ERISA Affiliate") is obligated to contribute to,
nor does any such entity have any liability or potential liability with respect
to, a "multiemployer plan," as defined in Section 4001(a)(3) of ERISA. No
liabilities associated with plans which are maintained or contributed to by any
SLC ERISA Affiliate and which are subject to title IV of ERISA could have a
Material Adverse Effect on SLC.

                  Section 3.13 Compliance with Worker Safety and Environmental
Laws. The properties, assets and operations of SLC and its Subsidiaries are in
compliance with all applicable Worker Safety Laws and Environmental Laws, except
for any violations that, individually or in the aggregate, would not have a
Material Adverse Effect on SLC. No hazardous materials have been Released by any
person at any property now owned, operated or leased by SLC or its Subsidiaries
or by SLC or a Subsidiary at any property formerly owned, operated or leased by
SLC or its Subsidiaries, except for such Releases that individually and in the
aggregate would not have a Material Adverse Effect on SLC. Neither SLC nor any
Subsidiary have received any request for information, notice of claim, demand or
notification that it is or may be potentially responsible with respect to any
investigation or clean-up of any threatened or actual Release. Except as set
forth in Section 3.13 of the SLC Letter and heretofore provided to ITI, within
the past five years, there have been no environmental inspections, studies,
audits, tests, reviews or other analyses conducted by a third party
environmental consultant or engineer in relation to any property or business now
or previously owned, operated or leased by SLC or its Subsidiaries. With respect
to such properties, assets and operations, including any previously owned,
leased or operated properties, assets or operations, there are no events,
conditions, circumstances, activities, practices, incidents, actions or plans of
SLC or any of its Subsidiaries that may interfere with or prevent compliance or
continued compliance with applicable Worker Safety Laws and Environmental Laws,
other than any such interference or prevention as would not, individually or in
the aggregate with any such other interference or prevention, have a Material
Adverse Effect on SLC.

any persons employed by or otherwise performing services primarily for SLC or
any of its Subsidiaries (the "SLC Business Personnel"), and there is no unfair
labor practice complaint or grievance against SLC or any of its Subsidiaries by
the National Labor Relations Board or any comparable state agency pending or
threatened in writing with respect to SLC Business Personnel, except where such
unfair labor practice, complaint or grievance would not have a Material Adverse
Effect on SLC. There is no labor strike, dispute, slowdown or stoppage pending

Subsidiaries which may interfere with the respective business activities of SLC
or any of its Subsidiaries, except where such dispute, strike or work stoppage

                  Section 4.2 No Solicitation. ITI shall not, nor shall it
permit any of its Subsidiaries to, nor shall it authorize or permit any officer,
director or employee of or any financial advisor, attorney or other advisor or
representative of, ITI or any of its Subsidiaries to, directly or indirectly (i)
solicit, initiate, induce or encourage the submission of, any ITI Takeover
Proposal (as hereafter defined), (ii) enter into any agreement contemplating or
with respect to any ITI Takeover Proposal, (iii) participate in any discussions
or negotiations regarding, or furnish to any person any information with respect
to, or take any other action to facilitate any inquiries or the making of any
proposal that constitutes, or may reasonably be expected to lead to, any ITI
Takeover Proposal or (iv) approve, endorse or recommend any ITI Takeover
Proposal; provided, however, that prior to the ITI Stockholders Meeting, this
Section 4.2 shall not prohibit ITI from furnishing nonpublic information
regarding ITI or its Subsidiaries to, or entering into discussions with, any
person in response to a Superior Proposal submitted by such person (and not
withdrawn) if (i) neither ITI nor any of its officers, directors, employees,
attorneys, financial advisors, agents or other representatives shall have
violated any of the restrictions set forth in this Section 4.2, (ii) prior to
furnishing such nonpublic information to, or entering into discussions with,
such person, ITI gives SLC written notice of ITI's intention to furnish
nonpublic information to, or enter into discussions with, such person, and ITI
receives from such person an executed confidentiality agreement containing
customary limitations on the use and disclosure of all nonpublic information
furnished to such person by or on behalf of ITI and (iii) prior to


                                       38
<PAGE>



furnishing any such nonpublic information to such person, ITI furnishes such
nonpublic information to SLC. ITI acknowledges and agrees that any violation of
any of the restrictions set forth in the preceding sentence by any officer,
director, employee, attorney, financial advisor, agent or other representative
of ITI, whether or not such person is purporting to act on behalf of ITI, shall
be deemed to constitute a breach of this Section 4.2 by ITI. ITI shall
immediately advise SLC orally and in writing of (x) any ITI Takeover Proposal
that is made or submitted by any such person, (y) the identity of the person
making or submitting such ITI Takeover Proposal and the terms thereof and (z)
any discussion or negotiation with respect to ITI Takeover Proposal that changes
the terms thereof. Notwithstanding anything herein to the contrary, if SLC
reasonably determines that a person who has made a Superior Proposal is a direct
competitor of ITI with a market share in wireless security systems that is
comparable to or larger than ITI's share of such market, SLC can, by written
notice to ITI, prohibit ITI from providing nonpublic information to such person.
ITI shall immediately cease and cause to be terminated any existing discussions
with any person that relate to any ITI Takeover Proposal. For purposes of this
Agreement, "ITI Takeover Proposal" means any proposal for a merger or other
business combination involving ITI or any of its Subsidiaries or any proposal or
offer to acquire in any manner, directly or indirectly, a substantial equity
interest in, a substantial portion of the voting securities of, or a substantial
portion of the assets of ITI or any of its Subsidiaries, other than the
transactions contemplated by this Agreement, and "Superior Proposal" means a
bona fide, unsolicited written ITI Takeover Proposal made by a third party the
terms of which a majority of the Board of Directors of ITI, taking into
consideration financial, legal, regulatory and other factors as they deem
relevant, determines in their reasonable good faith judgment, based on the
advice of financial advisors, outside counsel and other advisors selected by
them, to be more favorable to ITI's stockholders than the terms of the Merger
(including a determination that the proposal is more favorable to ITI's
stockholders than the Merger from a financial point of view) and the negotiation
of which proposal is consistent with the Board's fiduciary obligations to the
ITI stockholders. ITI has provided to SLC forms of confidentiality agreements
(the "Confidentiality Agreements") executed by all Persons to whom ITI has given
confidential information in the last twelve months. ITI will not agree to any
amendment, modification or waiver of any provision of any Confidentiality
Agreement without the prior written consent of SLC, and will enforce all of its
rights to the full extent provided by the Confidentiality Agreements.

                  Section 4.3 SLC Stockholder Agreement. During the period from
the date of this Agreement through the Effective Time, the SLC Stockholder will
not transfer any shares of SLC Common Stock to any other Person unless the
transferee agrees that such transfer shall not rescind, change or invalidate
such SLC Stockholder's vote in favor of this Agreement and the transactions
contemplated hereby.

                  Section 4.4 Reorganization. During the Pre-Closing Period,
unless the other party shall otherwise agree in writing, none of ITI, SLC or any
of their respective Subsidiaries shall knowingly take or fail to take any action
which action or failure would jeopardize the qualification of the Merger as a
reorganization within the meaning of Section 368(a) of the Code.

                  Section 4.5 Actions Inconsistent With Ruling. During the
Pre-Closing Period, SLC shall take no action, and shall use its reasonable best
efforts to prevent the occurrence of any event or condition, that would be
inconsistent with its May 13, 1997 tax-free spin-off IRS ruling or any
supplemental IRS ruling or opinion of counsel contemplated by Section 6.3(d).
Each of ITI and SLC shall reasonably cooperate in making changes requested by
SLC not later than five days prior to the proposed mailing of the Proxy
Statement to the structure of the transactions contemplated hereby in a manner
that is likely to produce a result that is favorable to SLC with respect to the
aforementioned tax rulings, so long as the effect of such changes does not
exceed $100,000 to ITI or delay receipt of such ruling.

                  Section 4.6 Redemption of Rights Plan. ITI shall not, during
the Pre-Closing Period (a) redeem the Shareholder Rights Plan or (b) implement
or adopt any other so-called "poison-pill," shareholder rights plan or other
similar plan.

                                    ARTICLE V

                              ADDITIONAL AGREEMENTS
                              ---------------------

                  Section 5.1 Stockholder Meeting. ITI will take all action
necessary under all applicable laws to, as soon as practicable following the
date of this Agreement, duly call, give notice of, convene and hold a meeting of
stockholders (the "ITI Stockholder Meeting") at a date reasonably approved by
SLC for the purpose of considering, acting upon and voting upon the adoption and
approval of the Merger and this Agreement and the transaction contemplated
hereby. ITI will, through its Board of Directors, unanimously recommend to its
stockholders the adoption and approval of the Merger and this Agreement and the
transaction contemplated hereby, shall use all reasonable best efforts to
solicit such adoption by its stockholders and shall not withdraw, amend or
revoke such recommendation; provided, however, that ITI's Board of Directors may
withdraw, amend or revoke such recommendation if (i) a Superior Proposal is made
to ITI and is not withdrawn and (ii) Section 4.2 has not been breached or
violated. Without limiting the generality of the foregoing, ITI agrees that its
obligations pursuant to the first sentence of this Section 5.1 shall not be
affected by the commencement, public proposal, public disclosure or
communication to ITI of an ITI Takeover Proposal. The Agreement shall be
submitted to the ITI stockholders at the ITI Stockholder Meeting whether or not
ITI's Board of Directors hereafter determines that the Agreement is no longer
advisable and recommends that the ITI stockholders reject it. Nothing in this
Section 5.1 is intended to affect any obligations under Rule 14e-2(a) of the
Exchange Act.

                  Section 5.2 Preparation of Proxy Statement.

                  (a) As promptly as practicable after the execution of this
Agreement, ITI shall cause to be prepared and filed with the Securities and
Exchange Commission a preliminary proxy statement relating to the Merger. SLC
shall furnish all information concerning it and the holders of its capital stock
as ITI may reasonably request in connection with the preparation thereof. ITI


                                       40
<PAGE>



shall furnish a draft of the preliminary proxy statement and any proposed
amendment or supplement thereto to SLC a reasonable time before its proposed
filing date, and shall make such changes thereto prior to filing thereof as SLC
shall reasonably request. Each of SLC and ITI shall use its reasonable best
efforts to have the preliminary proxy statement cleared for use as promptly as
practicable after such filing. As promptly as practicable after the Proxy
Statement shall have been so cleared, ITI shall mail the Proxy Statement to its
stockholders. ITI and its representatives shall allow SLC to participate in any
substantive communication with the SEC.

                  (b) Each party to the Agreement hereby (i) consents to the use
of its name and, on behalf of its Subsidiaries and affiliates, the names of such
Subsidiaries and affiliates, and to the inclusion of financial statements and
business information relating to such party and its Subsidiaries and affiliates
(in each case, to the extent required by applicable securities laws) in the
Proxy Statement, (ii) agrees to use its reasonable best efforts to obtain the
written consent of any person or entity retained by it which may be required to
be named (as an expert or otherwise) in such Proxy Statement (provided that
reasonable best efforts, as used herein and elsewhere in this Agreement, shall
not include expending money other than as is customary for professional advisors
and reasonable expenses), (iii) agrees to cooperate, and agrees to use its
reasonable efforts to cause its Subsidiaries and affiliates to cooperate, with
any legal counsel, investment banker, accountant or other agent or
representative retained by any of the parties specified in clause (i) in
connection with the preparation of any and all information required, as
determined after consultation with each party's counsel, by applicable
securities laws to be disclosed in any such Proxy Statement, and (iv) agrees to
notify the other promptly upon the receipt of any comments from the SEC or its
staff and of any request by the SEC or its staff for amendments or supplements
to the Proxy Statement or for additional information and will supply the other
with copies of all correspondence between such party or any of its
representatives, on one hand, and the SEC or its staff, on the other hand, with
respect to the Proxy Statement.

                  (c) If at any time prior to the Effective Time SLC discovers
any event or circumstance relating to SLC or any of its Subsidiaries, or its
officers or directors, which should be set forth in an amendment or supplement
to the Proxy Statement, SLC shall promptly inform ITI of such event or
circumstance. If at any time prior to the Effective Time ITI discovers any event
or circumstance relating to ITI or any of its Subsidiaries, or its or their
respective officers or directors which should be set forth in an amendment or
supplement to the Proxy Statement, ITI shall inform SLC of such event or
circumstance. Promptly upon discovery of or upon learning of any event or
circumstance required to be set forth in a supplement to the Proxy Statement,
ITI and SLC shall prepare such supplement and cause it to be sent to ITI's
stockholders.

                  Section 5.3 Private Placement of Common Stock.

                  (a) The SLC Stockholder, simultaneous with the execution of
this Agreement, has executed a letter containing certain representations
regarding an investment in the private offering of Common Stock as part of the
Merger.

qualifications under any applicable state securities laws in connection with the
Merger.

                  Section 5.4 Comfort Letters.

                  (a) ITI shall use its reasonable best efforts to cause to be
delivered to SLC "comfort" letters of PricewaterhouseCoopers, ITI's independent

reasonably satisfactory to SLC and reasonably customary in scope and substance
for letters delivered by independent public accountants in connection with
transactions such as those contemplated by this Agreement.

                  (b) SLC shall use its reasonable best efforts to cause to be
delivered to ITI "comfort" letters of Arthur Andersen, SLC's independent public
accountants, dated within two days of the date of the Proxy Statement and as of
the Effective Time, and addressed to ITI and SLC, in form and substance
reasonably satisfactory to ITI and reasonably customary in scope and substance
for letters delivered by independent public accountants in connection with
transactions such as those contemplated by this Agreement.

                  Section 5.5 Access to Information. Subject to currently
existing contractual and legal restrictions applicable to ITI or to SLC or any
of their Subsidiaries, each of ITI and SLC shall, and shall cause each of its
Subsidiaries to, afford to the officers, employees, accountants, counsel,
financial advisors and other representatives of the other party hereto
reasonable access to, and permit them to make such inspections as they may
reasonably require of, during normal business hours during the Pre-Closing
Period, all their respective properties, books, contracts, customers, suppliers,
commitments and records (including, without limitation, the work papers of
independent accountants, if available and subject to the consent of such
independent accountants and Tax Returns), and, during such period, ITI and SLC

Agreement of any party hereto or any condition to the obligations of the parties
hereto. All information obtained by ITI or SLC pursuant to this Section 5.5
shall be kept confidential in accordance with the Confidentiality Agreement,
dated April 22, 1998 (as amended by the First Amendment dated June 3, 1999, the
Second Amendment dated June 24, 1999, and the Third Amendment dated August 24,
1999), between ITI and SLC (the "Confidentiality Agreement").

                  Section 5.6 Fees and Expenses.

                  (a) Except as provided in this Section 5.6 whether or not the
Merger is consummated, all costs and expenses incurred in connection with this
Agreement and the transactions contemplated hereby including, without
limitation, the fees and disbursements of counsel, financial advisors and
accountants, shall be paid by the party incurring such costs and expenses,
provided that all printing expenses and all filing fees (including, without

                  (b) In the event of the termination of this Agreement and the
abandonment of the Merger at any time by ITI or SLC pursuant to Sections 7.1(d),
(e), (f) or (g) and in order to compensate SLC for the expenses associated with
the negotiation of this Agreement and the other matters contemplated hereby, ITI
shall, within two business days following such termination, pay SLC a fee of
$10,000,000 in immediately available funds; provided, however, that such fee
shall be payable with respect to a termination pursuant to Section 7.1(d) only
if, and then when, ITI directly or indirectly enters into a definitive agreement
relating to an ITI Takeover Proposal within one year of such termination.

                  (c) In the event of the termination of this Agreement and the
abandonment of the Merger at any time by ITI pursuant to Section 7.1(b), and if
the condition contained in Section 6.3(d) or 6.3(f) has not been satisfied or
waived by SLC and all the other conditions contained in Sections 6.1, 6.3(a),
6.3(c) and 6.3(e) have been satisfied or waived as though the date of
termination were considered as the Effective Time, SLC shall, within two
business days following such termination, reimburse ITI in immediately available
funds for its reasonable out-of-pocket expenses (not to exceed $2,000,000)
incurred after the date hereof in carrying out its obligations under this
Agreement.

                  Section 5.7 Reasonable Best Efforts.

                  (a) Subject to Section 5.7(c), upon the terms and subject to
the conditions set forth in this Agreement, each of the parties agrees to use
reasonable best efforts to take, or cause to be taken, all actions, and to do,
or cause to be done, and to assist and cooperate with the other parties in
doing, all things necessary, proper or advisable to consummate and make
effective, in the most expeditious manner practicable, the Merger and the other
transactions contemplated by this Agreement, including, but not limited to: (i)
the obtaining of all necessary actions or non- actions, waivers, consents and
approvals from all Governmental Entities and the making of all necessary
registrations and filings (including filings with Governmental Entities) and the
taking of all reasonable steps as may be necessary to obtain an approval or
waiver from, or to avoid an action or proceeding by, any Governmental Entity
(including those in connection with the HSR Act and State Takeover Approvals),
(ii) the obtaining of all necessary consents, approvals or waivers from third
parties, (iii) the defending of any lawsuits or other legal proceedings, whether
judicial or administrative, challenging this Agreement or the consummation of
the transactions


                                       43
<PAGE>



contemplated hereby, including seeking to have any stay or temporary restraining
order entered by any court or other Governmental Entity vacated or reversed and
(iv) the execution and delivery of any additional instruments necessary to
consummate the transactions contemplated by this Agreement. The parties agree to
file the initial notification required under the HSR Act within 30 days of the
date hereof. No party to this Agreement shall consent to any voluntary delay of
the consummation of the Merger at the behest of any Governmental Entity without
the consent of the other party to this Agreement, which consent shall not be
unreasonably withheld. Without the prior consent of the other party (not to be
unreasonably withheld) no party or its representatives shall take any action
contemplated by clause (i) above, or make any proposal to a Governmental Entity
with respect to the foregoing; provided, however, that SLC may file the request
for the supplemental ruling contemplated by Section 5.12 and any supplemental
filings related thereto without the consent of ITI. Neither party nor its
representatives shall engage in any communication with any Governmental Entity
with respect to the actions contemplated by clause (i) above without the
participation of the other party or its representatives. If any lawsuits or
other legal proceedings of the type contemplated by clause (iii) above are
instituted, the defendant shall keep the other party reasonably informed of the
proceeding. No lawsuit or legal proceeding of the type contemplated by clause
(iii) shall be settled by one party without the prior written consent of the
other party.

                  (b) Each party shall use its reasonable best efforts to not
take any action, or enter into any transaction, which would cause any of its
representations or warranties contained in this Agreement to be untrue or result
in a breach of any covenant made by it in this Agreement.

                  (c) Notwithstanding anything to the contrary contained in this
Agreement, in connection with any filing or submission required or action to be
taken by either ITI or SLC to effect the Merger and to consummate the other
transactions contemplated hereby, neither party shall without the other party's
prior written consent, commit to any divestiture transaction, and none of SLC,
ITI or any of their Subsidiaries shall be required to divest or hold separate or
otherwise take or commit to take any action that limits its freedom of action
with respect to, or its ability to retain, any of its material businesses,
product lines or assets or that otherwise would have a Material Adverse Effect
on it.

                  (d) Each of ITI and SLC agrees to cooperate and coordinate
efforts to integrate their respective benefit plans.

                  Section 5.8 Public Announcements. Each of the parties agrees
that it shall not, nor shall any of their respective affiliates, issue or cause
the publication of any press release or other public announcement with respect
to the Merger, this Agreement or the other transactions contemplated hereby
without the prior approval of the other party, except such disclosure as may be
required by law or by any listing agreement with Nasdaq or a national securities
exchange; provided, if such disclosure is required by law or any such listing
agreement, such disclosure may not be made without prior consultation of the
other parties.

                  Section 5.9 State Takeover Laws. If any "fair price,"
"business combination" or "control share acquisition" statute or other similar
statute or regulation shall become applicable to the transactions contemplated
hereby, ITI and SLC and their respective Boards of Directors shall use their
reasonable best efforts to grant such approvals and take such actions as are
necessary so that the transactions contemplated hereby and thereby may be
consummated as promptly as practicable on the terms contemplated hereby and
thereby and otherwise act to minimize the effects of any such statute or
regulation on the transactions contemplated hereby and thereby.

                  Section 5.10 Indemnification; Directors and Officers
Insurance. For six years from and after the Effective Time, ITI agrees to
indemnify and hold harmless all past and present officers and directors of SLC
and its Subsidiaries to the same extent such persons are indemnified as of the
date of this Agreement by SLC pursuant to SLC's Certificate of Incorporation,
Bylaws or agreements in existence on the date hereof for acts or omissions
occurring at or prior to the Effective Time. ITI shall provide for an aggregate
period of not less than six years from the Effective Time, ITI's and SLC's
directors and officers on the date hereof an insurance and indemnification
policy that provides coverage for events occurring prior to the Effective Time
that is substantially similar (with respect to limits and deductibles) to ITI's
existing policy or, if substantially equivalent insurance coverage is
unavailable, the best available coverage; provided, however, that the annual
premiums for such coverage will not exceed 200% of the annual premiums currently
paid by SLC for such coverage.

                  Section 5.11 Notification of Certain Matters. ITI shall use
its reasonable best efforts to give prompt notice to SLC, and SLC shall use its
reasonable best efforts to give prompt notice to ITI, of: (i) the occurrence, or
non-occurrence, of any event the occurrence, or non-occurrence, of which it is
aware and which has caused or would be reasonably likely to cause (x) any
representation or warranty contained in this Agreement to be untrue or
inaccurate in any material respect or (y) any covenant, condition or agreement
contained in this Agreement not to be complied with or satisfied in all material
respects, (ii) any failure of ITI or SLC, as the case may be, to comply in a
timely manner with or satisfy any covenant, condition or agreement to be
complied with or satisfied by it hereunder or (iii) any change or event which
would be reasonably likely to have a Material Adverse Effect on ITI or SLC, as
the case may be; provided, however, that the delivery of any notice pursuant to
this Section 5.11 shall not limit or otherwise affect the remedies available
hereunder to the party receiving such notice.

                  Section 5.12 IRS Ruling Letter. SLC shall use its reasonable
best efforts to obtain and ITI shall cooperate in obtaining from the IRS a
supplemental ruling to its May 13, 1997 tax-free spin-off ruling to the effect
that the transactions contemplated by this Agreement are consistent with, and
would not have an adverse effect on the conclusion reach in the prior ruling and
SLC shall file a request therefor not later than five business days after the
date of this Agreement. Notwithstanding the foregoing, SLC may withdraw its
request for such supplemental ruling if it reasonably believes that the
condition set forth in Section 6.3(d) will not be satisfied.

applicable law and the Certificate of Incorporation and Bylaws of ITI and the

                  (i) Any applicable waiting period (and any extension thereof)
         applicable to the consummation of the Merger under the HSR Act shall
         have expired or been terminated.

                  (ii) All authorizations, consents, orders, declarations or
         approvals of, or filings with, or terminations or expirations of
         waiting periods imposed by, any Governmental Entity, which the failure
         to obtain, make or occur would have the effect of making the Merger or
         any of the transactions contemplated hereby illegal or would have,
         individually or in the aggregate, a Material Adverse Effect on ITI
         (assuming the Merger had taken place), shall have been obtained, shall
         have been made or shall have occurred.

                  (d) No Order. After the date hereof, no court or other
Governmental Entity having jurisdiction over ITI or SLC, or any of their
respective Subsidiaries, shall have enacted, issued, promulgated, enforced or
entered any law, rule, regulation, executive order, decree, injunction or other
order (whether temporary, preliminary or permanent) which is then in effect and
has the effect of prohibiting the Merger or any of the transactions contemplated
hereby (the parties having used their respective reasonable best efforts
(consistent with the provisions of this Agreement) to remove any such
injunction, order or decree).

                  Section 6.2 Conditions to Obligation of ITI to Effect the
Merger. The obligations of ITI to effect the Merger shall be subject to the
fulfillment at or prior to the Effective Time of the following additional
conditions:

                  (a) Performance of Obligations; Representations and
Warranties. SLC shall have performed in all material respects each of its
agreements contained in this Agreement required to be performed on or prior to
the Effective Time. Each of the representations and warranties of SLC set forth
in Sections 3.1, 3.2 and 3.3 (the "SLC Specified Representations") shall be true
and correct on and as of the Effective Time as if made on and as of such date
(except for the representations and warranties which address matters only as of
a certain date which shall be true and correct as of such certain date).
Excluding the SLC Specified Representations, each of the other representations
and warranties of SLC contained in this Agreement shall be true and correct on
and as of the Effective Time as if made on and as of such date (other than
representations and warranties which address matters only as of a certain date


                                       47
<PAGE>



which shall be true and correct as of such certain date), in each case except as
expressly contemplated or permitted by this Agreement and except for
inaccuracies or misrepresentations of any representation or warranty of SLC
(other than the SLC Specified Representations) which, when taken together with
all other inaccuracies or misrepresentations of representations or warranties of
SLC (other than the SLC Specified Representations) would not have a Material
Adverse Effect on SLC. ITI shall have received certificates signed on behalf of
SLC by its Chief Executive Officer and its Chief Financial Officer as to the
matters set forth in this Section 6.2(a).

                  (b) Tax Opinion. ITI shall have received an opinion, in form
and substance reasonably satisfactory to it, from Dorsey & Whitney LLP dated as
of the Effective Time, substantially to the effect that, on the basis of the
facts, representations and assumptions set forth in such opinions which are
consistent with the state of facts existing at the Effective Time, the Merger
will be treated for Federal income tax purposes as a reorganization within the
meaning of Section 368(a) of the Code and that accordingly no gain or loss will
be recognized by SLC or ITI as a result of the Merger. In rendering such
opinion, such counsel may require and rely upon representations and covenants
including those contained in certificates of officers of ITI, SLC and others.

                  (c) Material Adverse Change. Since the date of this Agreement,
there shall have been no material adverse change in, and no event, occurrence or
development in the business of SLC or its Subsidiaries that, taken together with
other events, occurrences and developments with respect to such business, would
have or would reasonably be expected to have a Material Adverse Effect on SLC.

                  (d) Indemnification Agreement. Immediately prior to the
Effective Time, Berwind Corporation and SLC shall have entered into the
Indemnification Agreement in the form of Exhibit D hereto.

                  Section 6.3 Conditions to Obligations of SLC to Effect the
Merger. The obligations of SLC to effect the Merger shall be subject to the
fulfillment at or prior to the Effective Time of the following additional
conditions:

                  (a) Performance of Obligations; Representations and
Warranties. ITI shall have performed in all material respects each of its
agreements contained in this Agreement required to be performed on or prior to
the Effective Time. Each of the representations and warranties of ITI set forth
in Sections 2.1, 2.2 and 2.3 (the "ITI Specified Representations") shall be true
and correct on and as of the Effective Time as if made on and as of such date
(except for the representations and warranties which address matters only as of
a certain date which shall be true and correct as of such certain date).
Excluding the ITI Specified Representations, each of the other representations
and warranties of ITI contained in this Agreement that is qualified by
materiality shall be true and correct on and as of the Effective Time as if made
on and as of such date (other than representations and warranties which address
matters only as of a certain date which shall be true and correct as of such
certain date) and as if made without any Material


                                       48
<PAGE>



Adverse Effect qualifications, in each case except as expressly contemplated or
permitted by this Agreement and except for inaccuracies or misrepresentations of
any representation or warranty of ITI (other than the ITI Specified
Representations) which, when taken together with all other inaccuracies or
misrepresentations of representations or warranties of ITI (other than the ITI
Specified Representations) would not have a Material Adverse Effect on ITI. SLC
shall have received certificates signed on behalf of ITI by each of its Chief
Executive Officer and its Chief Financial Officer as to the matters set forth in
this Section 6.3(a).

                  (b) Tax Opinion. SLC shall have received an opinion, in form
and substance reasonably satisfactory to it, from Dechert Price & Rhoads, dated
as of the Effective Time, substantially to the effect that, on the basis of the
facts, representations and assumptions set forth in such opinions which are
consistent with the state of facts existing at the Effective Time, the Merger
will be treated for Federal income tax purposes as a reorganization within the
meaning of Section 368(a) of the Code and that accordingly:

                  (i) No gain or loss will be recognized by SLC or ITI as a
         result of the Merger;

                  (ii) No gain or loss will be recognized by the stockholders of
         SLC who exchange their SLC stock for ITI stock pursuant to the Merger
         (except with respect to cash received in lieu of a fractional share
         interest in Common Stock);

                  (iii) The tax basis of the Common Stock received by the
         stockholders in exchange for SLC Common Stock in the Merger will be the
         same as the tax basis of the SLC Common Stock surrendered in exchange
         therefor; and

                  (iv) The holding period of the Common Stock received by a
         stockholder of SLC pursuant to the Merger will include the period
         during which the SLC Common Stock surrendered therefor was held,
         provided the SLC Common Stock is a capital asset in the hands of the
         stockholder of SLC at the time of the Merger.

In rendering such opinion, such counsel may require and rely upon
representations and covenants including those contained in certificates of
officers of ITI, SLC and others.

                  (c) Material Adverse Change. Since the date of this Agreement,
there shall have been no material adverse change in, and no event, occurrence or
development in the business of ITI or its Subsidiaries that, taken together with
other events, occurrences and developments with respect to such business, would
have or would reasonably be expected to have a Material Adverse Effect on ITI.

                  (d) IRS Issues. SLC shall have received from the IRS a
supplemental ruling to its May 13, 1997 tax-free spin-off ruling to the effect
that the transactions contemplated by this Agreement are consistent with the
prior ruling, such supplemental ruling being in form and content acceptable to
SLC, in its sole discretion, and SLC is satisfied, in its sole discretion, that


                                       49
<PAGE>



no event or condition has occurred that would be inconsistent with, or have an
adverse effect on the conclusions reached in, the original or supplemental IRS
ruling or request.

                  (e) Registration Rights. ITI (or its assignees) shall have
entered into a Registration Rights Agreement substantially in the form attached
hereto as Exhibit C.

                  (f) Since the date of this Agreement, (i) trading in
securities generally on the New York Stock Exchange or NASDAQ shall not have
been suspended or materially limited, (ii) a general moratorium on commercial
banking activities in New York shall not have been declared by either federal or
state authorities, or (iii) there shall not have occurred any outbreak or
escalation of hostilities or other international or domestic calamity, crisis or
change in political, financial or economic conditions, the effect thereof on the
global financial markets makes it impossible for ITI to receive the proceeds of
financing on terms and in amounts substantially similar to the terms set forth
in the Financing Commitment.

                                   ARTICLE VII

                        TERMINATION, AMENDMENT AND WAIVER

                  Section 7.1 Termination. This Agreement may be terminated at
any time prior to the Effective Time, whether before or after any approval of
the matters presented in connection with the Merger by the stockholders of ITI:

                  (a) by the mutual written consent of ITI and SLC;

                  (b) by either ITI or SLC if the Effective Time will not have
occurred on or before the six-month anniversary of the date of this Agreement
("Upset Date"); provided, however, that the right to terminate this Agreement
pursuant to this Section 7.1(b) shall not be available to any party whose
failure to fulfill any of its obligations contained in this Agreement has been
the cause of, or resulted in, the failure of the Merger to have occurred on or
prior to the aforesaid date; and provided, further, that either ITI or SLC may
extend the Upset Date up to two times in the aggregate for an additional
one-month period each time by written notice given no less than three days prior
to the scheduled Upset Date.

                  (c) by either ITI or SLC if (i) a statute, rule, regulation or
executive order will have been enacted, entered or promulgated prohibiting the
consummation of the Merger substantially on the terms contemplated hereby or
(ii) an order, decree, ruling or injunction will have been entered permanently
restraining, enjoining or otherwise prohibiting the consummation of the Merger
substantially on the terms contemplated hereby and such order, decree, ruling or
injunction will have become final and non-appealable; provided, that the party
seeking to terminate this Agreement pursuant to this provision will have used
its reasonable best efforts to remove such injunction, order or decree;



                                       50
<PAGE>



                  (d) by either ITI or SLC if the approvals of the Merger will
not have been obtained by reason of the failure to obtain the required vote at a
duly held meeting of ITI stockholders or of any adjournment thereof;

                  (e) by ITI or SLC if ITI enters into a merger, acquisition or
other agreement (including an agreement in principle) to effect a Superior
Proposal or the Board of Directors of ITI resolves to do so prior to
satisfaction of the conditions set forth in Section 6.1(a); provided, however,
that ITI may not terminate this Agreement pursuant to this Section 7.1(e) unless
(i) ITI has delivered to SLC a written notice of ITI's intent to enter into such
an agreement to effect the Superior Proposal, (ii) five business days have
elapsed following delivery to SLC of such written notice by ITI and (iii) during
such five business day period ITI has fully cooperated with SLC, including,
without limitation, informing SLC of the terms and conditions of the ITI
Takeover Proposal and the identity of the Person making the ITI Takeover
Proposal, with the intent of enabling SLC to agree to a modification of the
terms and conditions of this Agreement so that the transactions contemplated
hereby may be effected and (iv) ITI has considered in good faith any
modification of the terms of this Agreement proposed by SLC during such five
business day period; provided, further, that ITI may not terminate this
Agreement pursuant to this Section 7.1(e) unless (i) at the end of such five
business day period the Board of Directors of ITI continues reasonably to
believe that the ITI Takeover Proposal constitutes a Superior Proposal, (ii)
prior to such termination ITI pays to SLC the amounts specified under Section
5.7 and (iii) simultaneously with such termination, ITI enters into a definitive
acquisition, merger or similar agreement to effect the Superior Proposal;

                  (f) by SLC if a tender offer or exchange offer for 20% or more
of the outstanding shares of capital stock of ITI is commenced prior to the ITI
Stockholder Meeting, and the Board of Directors of ITI fails to recommend
against acceptance of such tender offer or exchange offer within the time period
presented by Rule 14e-2 by its stockholders;

                  (g) by SLC if the board of directors of ITI at any time
withdraws, modifies or revokes its recommendation of its support for the Merger,
or if upon a request by SLC, does not confirm its recommendation and support for
the Merger;

                  (h) by ITI or SLC if there shall have been a material breach
by the other of any of its representations, warranties, covenants or agreements
contained in this Agreement and such breach will not have been cured within 30
days after notice will have been received by the party alleged to be in breach;

                  (i) by ITI or SLC if SLC shall have withdrawn the request for
a supplemental ruling as permitted by Section 5.12; or

                  (j) by SLC if there shall have been a material breach by any
of the other parties thereto of any of their respective representations,
warranties, covenants or agreements contained in any of the Voting Support
Agreements.

                  The right of any party hereto to terminate this Agreement
pursuant to this Section 7.1 shall remain operative and in full force and effect
regardless of any investigation made by or on behalf of any party hereto, any
person controlling any such party or any of their respective officers or
directors, whether prior to or after the execution of this Agreement.

                  Section 7.2 Effect of Termination. In the event of termination
of this Agreement by either ITI or SLC, as provided in Section 7.1, this
Agreement shall forthwith become void and there shall be no liability hereunder
on the part of ITI or SLC or their respective officers or directors (except for
the last sentence of Section 5.5 and the entirety of Section 5.6, which shall
survive the termination); provided, however, that nothing contained in this
Section 7.2 shall relieve any party hereto from any liability for any willful
breach of this Agreement giving rise to such termination.

                  Section 7.3 Amendment. This Agreement may be amended by the
parties hereto, by or pursuant to action taken by their respective Boards of
Directors, at any time before or after approval of the matters presented in
connection with the Merger by the stockholders of ITI, but, after any such
approval, no amendment shall be made which by law requires further approval by
such stockholders without such further approval. This Agreement may not be
amended except by an instrument in writing signed on behalf of each of the
parties hereto.

                  Section 7.4 Waiver. At any time prior to the Effective Time,
the parties hereto may (i) extend the time for the performance of any of the
obligations or other acts of the other parties hereto, (ii) waive any
inaccuracies in the representations and warranties contained herein or in any
document delivered pursuant hereto and (iii) waive compliance with any of the
agreements or conditions contained herein which may legally be waived.
Notwithstanding the forgoing, no failure or delay by ITI or SLC will operate as
a waiver thereof nor will any single or partial exercise thereof preclude any
other or further exercise thereof or the exercise of any other right hereunder.
Any agreement on the part of a party hereto to any such extension or waiver
shall be valid only if set forth in an instrument in writing signed on behalf of
such party.

                                  ARTICLE VIII

FOR IMMEDIATE RELEASE

ITI TECHNOLOGIES, INC. TO MERGE WITH SLC TECHNOLOGIES, INC. IN A STOCK AND CASH
MERGER

ST. PAUL AND PORTLAND - SEPTEMBER 29, 1999

ITI TECHNOLOGIES, (ITII, NASDAQ) and SLC Technologies, Inc. have reached a
definitive agreement to merge, creating a global security, life safety, systems
software and communications company with expected 1999 revenues of approximately
$550 million. The combined company brings together two industry leaders with
technology and channel strengths that are uniquely complementary in an industry
growing at a rate in excess of 10 percent annually. The merger is structured as
a stock-for-stock merger under which ITI shareholders may elect to receive
$36.50 in cash for up to 50 percent of their shares in aggregate.

The merger brings together ITI's leadership in the North American market for
wireless residential security systems with SLC's significant global position in
the commercial and enterprise solutions markets. The transaction is expected to
close in the first quarter of 2000. The companies expect to achieve annual cost
savings of at least $10 million and generate significant new revenue
opportunities. With anticipated synergies, the merger is expected to be
accretive to ITI's projected First Call consensus 2000 earnings per share of
$2.28 and significantly accretive to 2000 cash earnings per share.

According to Ken Boyda, CEO and President of SLC, who will become the CEO and
President of the merged entity, "the combination of ITI and SLC will create a
powerful entity with the broad product offering, integrated technological
capabilities, and global presence necessary to lead our industry." "The merger
will provide ITI with expanded access to international markets and the
opportunity to bring its wireless technology into access control, CCTV, and
other high-growth areas of the industry. At the same time, SLC will strengthen
its residential controls and wireless systems offerings. The resultant company
will be a technology leader that will provide quality integrated solutions to
the global marketplace and serve as a strong foundation for continued growth
within the $10 billion industry."

According to Tom Auth, Chairman, CEO and President of ITI, who will be Chairman
of the merged entity, "this is a marriage of two very capable industry leaders
that will raise our global profile and enhance our customer support." "There are
strong synergies resulting from this merger, both in gaining new revenues as
well as reducing costs. A significant growth opportunity exists to immediately
market ITI's products through SLC's established 21-country European sales
organization. Manufacturing economies of scale, purchasing benefits, and the
potential for streamlined plant operations will also produce significant cost
savings."

ITI, a manufacturer of electronic security equipment, has long been recognized
as the leading designer and manufacturer of wireless systems for the rapidly
expanding wireless residential security systems market. ITI has recently
introduced new products, which incorporate its



                                       1

wireless technology, directed at the commercial security and fire protection
markets. ITI, headquartered in North St. Paul, Minnesota, has manufacturing
facilities in North St. Paul, Minnesota, Gladewater, Texas, and Navajoa, Mexico,
and employs over 640 people. ITI's sales were $109 million in 1998, with
earnings before interest, taxes, depreciation and amortization of $25.2 million.

SLC is a global integrated communications technology company for security and
life safety systems. SLC offers commercial security and fire protection, CCTV,
electronic access control, high-end RFID and fiber optic communication systems
focusing on three customer groups--residential, commercial and enterprise
solutions. SLC's global reach includes sales and technical support organizations
in 27 countries and strategically positioned manufacturing and logistics
organizations in the United States, the Netherlands, Ireland, Australia and
China. SLC, headquartered in Portland, Oregon, employs over 2,400 employees
worldwide and is owned by the Berwind Group, a Philadelphia-based private
company. SLC, with 1998 sales of $376 million and earnings before interest,
taxes, depreciation and amortization of $65.5 million adjusted for expenses to
be eliminated as a result of the transaction, has grown its revenues from $32
million and earnings before interest, taxes, depreciation and amortization from
$2.4 million in 1990 through a combination of organic growth and acquisitions.

The transaction is structured as a stock-for-stock merger of SLC into ITI, with
ITI issuing approximately 15.2 million shares to SLC. ITI shareholders will have
the right to elect to receive from the newly merged company $36.50 in cash at
closing for each share of ITI stock, subject to the limitation that no more than
50 percent of the total number of shares of ITI common stock issued and
outstanding immediately prior to the closing be exchanged for cash. If ITI
shareholders elect to exchange more than 50 percent of the aggregate shares of
ITI for cash, then the shares eligible to be exchanged shall be reduced on a pro
rata basis so that 50 percent of the issued and outstanding common stock of ITI
immediately prior to the closing are exchanged for cash.

The transaction will be tax-free to shareholders, except for those shares that
ITI shareholders elect to exchange for cash. As a result of the transaction, SLC
shareholders will have a 63.5 percent ownership stake in the new 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 ITI outstanding
common stock is exchanged for cash. The transaction will be treated as a
purchase by SLC for accounting purposes.

The merger, which has been unanimously approved by the Board of Directors of
both companies, is subject to approval by ITI's shareholders, receipt by SLC of
a supplemental ruling from the IRS relating to SLC's 1997 spin-off from its
former parent, approval by regulatory authorities, and customary closing
conditions. The supplemental ruling is to confirm that this transaction is
consistent with SLC's 1997 IRS spin-off ruling.
