     Any stockholder desiring to tender all or any portion of his Shares, and
the associated Rights, should either (a) complete and sign the appropriate
Letter of Transmittal (or a facsimile thereof) in accordance with the
instructions in the Letter of Transmittal and mail or deliver it together with

Rights) are not immediately available or, in the case of Class A Shares, who

To: All Holders of Shares of Class A Common Stock (Including the
    Associated Series A Preferred Stock Purchase Rights), Class B
    Common Stock (Including the Associated Series B Preferred
    Stock Purchase Rights) and Class C Common Stock (Including the
    Associated Series C Preferred Stock Purchase Rights) of
    Reliance Electric Company:
 
                                  INTRODUCTION
 
     ROK Acquisition Corporation (the "Purchaser"), a Delaware corporation and a
wholly-owned subsidiary of Rockwell International Corporation, a Delaware
corporation ("Rockwell"), hereby offers to purchase (i) all outstanding shares
of Class A Common Stock, par value $.01 per share (the "Class A Shares"), of
Reliance Electric Company, a Delaware corporation (the "Company"), and (unless
and until the Purchaser declares that the Rights Condition (as defined below)
has been satisfied) the associated Series A preferred stock purchase rights (the
"Class A Rights") issued pursuant to the Rights Agreement, dated as of August
29, 1994, between the Company and Society National Bank, as Rights Agent (as the
same may be amended, the "Rights Agreement"), at a purchase price of $30 per
Class A Share (and associated Class A Right), net to the seller in cash, without
interest thereon, (ii) all outstanding shares of Class B Common Stock, par value
$.01 per share (the "Class B Shares"), of the Company and (unless and until the
Purchaser declares that the Rights Condition has been satisfied) the associated
Series B preferred stock purchase rights (the "Class B Rights") issued pursuant
to the Rights Agreement at a purchase price of $30 per Class B Share (and
associated Class B Right), net to the seller in cash, without interest thereon
and (iii) all outstanding shares of Class C Common Stock, par value $.01 per
share (the "Class C Shares" and, together with the Class A Shares and the Class
B Shares, the "Shares"), of the Company and (unless and until the Purchaser
declares that the Rights Condition has been satisfied) the associated Series C
preferred stock purchase rights (the "Class C Rights" and, together with the
Class A Rights and the Class B Rights, the "Rights") issued pursuant to the
Rights Agreement at a purchase price of $81.24 per Class C Share (and associated
Class C Right), net to the seller in cash, without interest thereon, in each
case upon the terms and subject to the conditions set forth in this Offer to
Purchase and in the related Letters of Transmittal (which together constitute
the "Offer"). Unless the context otherwise requires, all references to Shares
shall include the associated Rights and all references to the Rights shall
include all benefits that may inure to holders of the Rights pursuant to the
Rights Agreement.
 
     Tendering stockholders will not be obligated to pay brokerage fees or
commissions or, except as set forth in Instruction 6 of the Letters of
Transmittal, stock transfer taxes on the purchase of Shares or Rights by the
Purchaser pursuant to the Offer. However, any tendering stockholder or other
payee who fails to complete and sign the Substitute Form W-9 that is included in
the Letters of Transmittal may be subject to a required backup federal income
tax withholding of 31% of the gross proceeds payable to such stockholder or
other payee pursuant to the Offer. See Section 3. The Purchaser will pay all
charges and expenses of Dillon, Read & Co. Inc., as Dealer Manager (the "Dealer
Manager"), First Chicago Trust Company of New York, as Depositary (the
"Depositary"), and Georgeson & Company Inc., as Information Agent (the
"Information Agent"), incurred in connection with the Offer. See Section 16.
 
     The purpose of the Offer and the Proposed Rockwell Merger (as defined
below) is to acquire control of, and the entire equity interest in, the Company.
The Purchaser currently intends, as soon as practicable following consummation
of the Offer, to seek to have the Company consummate a merger or similar
business combination with the Purchaser (the "Proposed Rockwell Merger")
pursuant to which each then outstanding Share (other than Shares owned by
Rockwell or any of its wholly-owned subsidiaries, Shares held in the treasury of
the Company and Shares held by stockholders who perfect appraisal rights under
the Delaware General Corporation Law (the "Delaware Law")) would be converted
into the right to receive cash in the same amount as received per applicable
Share in the Offer, and the Company would become a wholly-owned subsidiary of
Rockwell. The Purchaser and Rockwell also reserve the right to solicit the votes
of the stockholders of the Company at any annual or special meeting of such
stockholders.
 
     The Offer is conditioned upon the fulfillment of certain conditions
described herein. The Offer will expire at 12:00 midnight, New York City time,
on Friday, November 18, 1994, unless extended.
<PAGE>   5
 
     In the summer of 1991, the Company explored with Rockwell a sale of the
Company. In connection therewith, Rockwell and the Company entered into an
agreement dated August 13, 1991 which provided, among other things, that
Rockwell would not, for a period of two years from the date of such agreement
(until August 13, 1993), engage in certain actions involving the Company,
including actions such as those contemplated by the Offer and the Proposed
Rockwell Merger. After reviewing certain preliminary information provided by the
Company, in late September 1991 Rockwell terminated activities in connection
with its consideration of a possible acquisition of the Company.
 
     Beginning in 1992, Rockwell, through its wholly-owned subsidiary
Allen-Bradley Company, Inc. ("Allen-Bradley"), began discussing and developing
various cooperative activities between Allen-Bradley and the Company, including
joint development of new products and reciprocal product branding. In the course
of such activities on October 27, 1993, John C. Morley, President and Chief
Executive Officer of the Company, met with Don H. Davis, Jr., at that time
President of Allen-Bradley, and appeared to be inviting Rockwell to "go beyond"
their existing cooperative efforts. On May 12, 1994, Mr. Davis, who then was
Executive Vice President and Chief Operating Officer of Rockwell, advised Mr.
Morley that Rockwell was interested in acquiring the Company. On July 12, 1994,
Mr. Davis and Donald R. Beall, Chairman of the Board and Chief Executive Officer
of Rockwell, met with Mr. Morley. At that time Mr. Beall informed Mr. Morley
that Rockwell was extremely interested in acquiring the Company. Mr. Morley said
that he would raise the matter with the Company's Board of Directors and would
respond promptly. On August 11, 1994, Mr. Morley advised Mr. Davis that he had
discussed Rockwell's interest in a proposed acquisition of the Company with the
Company's Board of Directors, but that he could not give Rockwell a definitive
response at that time.
 
     On August 30, 1994, the Company announced that it had entered into the
Agreement and Plan of Merger, dated as of August 30, 1994 (the "General Signal
Merger Agreement"), with General Signal Corporation ("General Signal"),
contemplating the merger of the Company with and into General Signal, with
General Signal being the surviving corporation (the "Proposed General Signal
Merger"). In the Proposed General Signal Merger, each Class A Share would be
converted into the right to receive 0.739 of one share of General Signal Common
Stock, par value $1.00 per share ("General Signal Common Stock"), each Class B
Share would be converted into the right to receive 0.739 of one share of General
Signal Class B Common Stock, par value $1.00 per share ("General Signal Class B
Common Stock") (or, at the election of the holder of Class B Shares, into 0.739
of one share of General Signal Common Stock), and each Class C Share would be
converted into the right to receive 2.001 shares of General Signal Class B
Common Stock (or, at the election of the holder of Class C Shares, into 2.001
shares of General Signal Common Stock). The General Signal Merger Agreement also
provides that for each share of General Signal Common Stock or General Signal
Class B Common Stock issued in the Proposed General Signal Merger, one General
Signal Common Stock purchase right or one General Signal Class B Common Stock
purchase right (as applicable) would be issued pursuant to the Rights Agreement
dated as of March 7, 1986, as amended, between General Signal and the rights
agent named therein (the "General Signal Rights Agreement"). Based on the
closing price of the General Signal Common Stock on the New York Stock Exchange
on August 29, 1994, the last trading day preceding the date of the announcement
of the General Signal Merger Agreement, of $37.25 per share, the Proposed
General Signal Merger would have had a value of approximately $1.4 billion or
$27.53 per Class A Share and Class B Share and $74.54 per Class C Share. Based
on the closing price of General Signal Common Stock on the New York Stock
Exchange on October 19, 1994 of $34.125 per share, the Proposed General Signal
Merger would have had a value of approximately $1.3 billion or $25.22 per Class
A Share and Class B Share and $68.28 per Class C Share. The Proposed General
Signal Merger is subject to certain conditions, including approval by the
stockholders of General Signal and the Company.
 
     The General Signal Merger Agreement provides that, among other things, the
Company and its subsidiaries, and their directors, officers, employees, agents
and representatives, will not solicit or encourage (including by way of
furnishing non-public information) any inquiry or proposal with respect to a
merger or other acquisition of the Company (a "Company Acquisition Transaction")
or communicate with any third party with respect to any Company Acquisition
Transaction or enter into any agreement requiring the Company to abandon the
Proposed General Signal Merger; provided that, in response to an unsolicited
written proposal with respect to a Company Acquisition Transaction from a
financially capable third party that
 
                                        2
<PAGE>   6
 
contains no financing condition, the Company may furnish non-public information
and negotiate or otherwise communicate with such third party if the Company's
Board of Directors determines that taking such action is reasonably likely to
lead to a Company Acquisition Transaction more favorable than the Proposed
General Signal Merger and determines (and the Company's outside counsel opines
in writing) that failing to take such action would constitute a breach of its
fiduciary duties.
 
     Rockwell believes that the Offer will permit the Company to furnish
Rockwell with non-public information pursuant to these provisions. The General
Signal Merger Agreement further provides that General Signal may terminate the
General Signal Merger Agreement in the event the Company's Board of Directors
(i) withdraws or adversely changes its recommendation with respect to the
Proposed General Signal Merger, (ii) recommends any proposal in respect of a
Company Acquisition Transaction or (iii) furnishes non-public information to or
negotiates or communicates with a third party with respect to any Company
Acquisition Transaction or publicly discloses a resolution to do any of the
foregoing. Under Section 9.05(b) of the General Signal Merger Agreement, if
General Signal terminates the General Signal Merger Agreement under such
circumstances, the Company will be required to reimburse General Signal for up
to $2.5 million of documented fees and expenses and to pay General Signal an
additional fee of $50 million.
 
     On October 19, 1994, the Board of Directors of Rockwell approved the
commencement of the Offer. On October 20, 1994 Rockwell sent a letter to the
Company and issued a press release stating that Rockwell's Board of Directors
had authorized the acquisition of the Company at a price of $30 per Class A
Share and an equivalent price for convertible shares (i.e., the Class B Shares
and Class C Shares, based on their respective conversion ratios of 1 to 1 and
2.708 to 1). See Section 10.
 
     The making of the Offer will enable the Purchaser to commence the process
of seeking regulatory approvals for its acquisition of the Company. See Section
15. In addition, by tendering Shares into the Offer, the Company's stockholders
effectively will be given the opportunity to express to the Company's Board of
Directors that they wish to be able to accept the Offer and to approve the
Proposed Rockwell Merger or a similar transaction with Rockwell.
 
     The Purchaser reserves the right to amend the Offer (including amending the
purchase price) upon entry into a merger agreement with the Company or otherwise
or to negotiate a merger agreement with the Company not involving a tender
offer. See Section 14. In the event that Rockwell is unable to negotiate a
definitive merger agreement with the Company, Rockwell will make a determination
whether to seek through a proxy contest at an annual meeting of stockholders or
a special meeting called for that purpose sufficient representation on the
Company's Board of Directors to cause the Board of Directors to approve the
Proposed Rockwell Merger and satisfy the Rights Condition and the Section 203
Condition (as defined below) and thereby permit the Offer and the Proposed
Rockwell Merger to be consummated. In connection therewith, Rockwell may solicit
calls for a special meeting of stockholders of the Company pursuant to Section
1.2 of the Company's By-Laws, which permits the holders of a majority of the
Company's voting stock (as well as the Chairman of the Board, the President or
the Board of Directors of the Company) to call such a special meeting.
 
     The Purchaser reserves the right to acquire additional Shares after
consummation of the Offer in open market purchases, through a tender offer, in
privately negotiated transactions or otherwise in order to obtain a sufficient
number of Shares to approve the transactions contemplated hereby. In addition,
after consummation of the Offer, whether or not the Purchaser acquires
additional Shares, the Purchaser currently intends to seek to enter into the
Proposed Rockwell Merger with the Company.
 
     THE OFFER DOES NOT CONSTITUTE A SOLICITATION OF PROXIES FOR ANY MEETING OR
A SOLICITATION OF CALLS FOR A SPECIAL MEETING OF THE COMPANY'S STOCKHOLDERS. ANY
SUCH SOLICITATION WHICH ROCKWELL OR THE PURCHASER MIGHT MAKE WOULD BE MADE ONLY
PURSUANT TO SEPARATE PROXY OR SOLICITATION MATERIALS COMPLYING WITH ALL
APPLICABLE REQUIREMENTS OF SECTION 14(A) OF THE SECURITIES EXCHANGE ACT OF 1934,
AS AMENDED (THE "EXCHANGE ACT"), AND THE RULES AND REGULATIONS PROMULGATED
THEREUNDER.

CERTAIN CONDITIONS TO THE OFFER
 
     The Offer is subject to the fulfillment of certain conditions, including
the following:
 
     Minimum Condition.  CONSUMMATION OF THE OFFER IS CONDITIONED (THE "MINIMUM
CONDITION") UPON THERE BEING VALIDLY TENDERED AND NOT WITHDRAWN PRIOR TO THE
EXPIRATION DATE (AS DEFINED IN SECTION 1) SHARES REPRESENTING AT LEAST A
MAJORITY OF THE TOTAL NUMBER OF OUTSTANDING CLASS A SHARES ON A FULLY DILUTED
BASIS (ASSUMING CONVERSION OF ALL OUTSTANDING CLASS B SHARES AND CLASS C SHARES
INTO CLASS A SHARES AND THE EXERCISE OF ALL OUTSTANDING OPTIONS).
 
     According to the Company's Registration Statement under the Exchange Act on
Form 8-A dated September 15, 1994 (the "Company 8-A"), as of August 30, 1994,
there were outstanding 32,909,939 Class A Shares, 3,161,032 Class B Shares and
5,250,000 Class C Shares. In addition, there were 1,259,365 Class A Shares
subject to issuance pursuant to outstanding stock options or options which may
be granted upon achievement of certain performance goals under various of the
Company's stock-based incentive plans. According to the Company's Restated
Certificate of Incorporation, as amended through September 21, 1994 (the
"Company Certificate of Incorporation"), and other publicly available
information, each Class B Share is convertible into one Class A Share and each
Class C Share is convertible into 2.708 Class A Shares upon the satisfaction of
certain conditions. As a result, the Purchaser believes that the Minimum
Condition would be satisfied if at least 25,773,669 Class A Equivalent Shares
(as defined below) were validly tendered and not withdrawn prior to the
Expiration Date. For purposes hereof, "Class A Equivalent Shares" shall mean
Class A Shares, Class B Shares and Class C Shares, where each Class A Share and
Class B Share shall be deemed to equal one Class A Equivalent Share and each
Class C Share shall be deemed to equal 2.708 Class A Equivalent Shares.
 
     The No Impediments Condition.  CONSUMMATION OF THE OFFER IS CONDITIONED
UPON THE GENERAL SIGNAL MERGER AGREEMENT HAVING BEEN TERMINATED WITHOUT ANY
PAYMENTS BY OR PENALTIES TO THE COMPANY (OTHER THAN ANY APPLICABLE PAYMENTS
PURSUANT TO SECTION 9.05(b) OF THE GENERAL SIGNAL MERGER AGREEMENT) AND THE
COMPANY NOT HAVING ENTERED INTO OR EFFECTUATED ANY NEW OR AMENDED AGREEMENTS
WITH GENERAL SIGNAL OR ANY OTHER PERSON OR ENTITY HAVING THE EFFECT OF IMPAIRING
THE ABILITY OF THE PURCHASER TO ACQUIRE THE COMPANY OR OTHERWISE DIMINISHING THE
EXPECTED ECONOMIC VALUE TO THE PURCHASER OF THE ACQUISITION OF THE COMPANY (THE
"NO IMPEDIMENTS CONDITION").
 
     Rights Condition.  CONSUMMATION OF THE OFFER IS CONDITIONED UPON THE RIGHTS
HAVING BEEN REDEEMED BY THE BOARD OF DIRECTORS OF THE COMPANY OR THE PURCHASER
BEING SATISFIED, IN ITS SOLE DISCRETION, THAT THE RIGHTS HAVE BEEN INVALIDATED
OR OTHERWISE ARE INAPPLICABLE TO THE OFFER AND THE PROPOSED ROCKWELL MERGER (THE
"RIGHTS CONDITION"). THE RIGHTS ARE DESCRIBED IN THE COMPANY 8-A, AND SUCH
DESCRIPTION IS SUMMARIZED IN SECTION 11.
 
     According to the Company 8-A, at any time until any person or entity
becomes an Acquiring Person (as defined in the Rights Agreement), the Company
may redeem the Rights in whole, but not in part, at a price of $.01 per Right,
subject to adjustment. According to the Company 8-A, until the close of business
on the Distribution Date (as defined in Section 11), the Rights will be
represented by and transferred with, and only with, the associated Shares and
the surrender for transfer of any of the certificates representing Shares (the
"Share Certificates") will also constitute the transfer of the Rights associated
with the Shares represented by such Share Certificates. According to the Company
8-A, the Rights Agreement provides that, as soon as practicable following the
Distribution Date, separate certificates representing Rights ("Rights
Certificates") will be mailed to holders of record of Shares as of the close of
business on the Distribution Date, and thereafter the Rights Certificates alone
will evidence the Rights.
 
                                        4
<PAGE>   8
 
     Based on publicly available information, the Purchaser believes that as of
October 20, 1994, the Rights were not exercisable, Rights Certificates had not
been issued and the Rights were evidenced by the Share Certificates. Under the
Rights Agreement, as a result of the announcement of the Offer, the Distribution
Date will be November 3, 1994, unless prior to such date the Company's Board of
Directors redeems the Rights or takes action to delay the Distribution Date. The
Distribution Date may also occur sooner. See Section 11.
 
     According to the Company 8-A, the Rights, if still outstanding, will expire
immediately prior to the effective time of the Proposed General Signal Merger.
The Purchaser believes that, in order to place the Purchaser on a level playing
field with General Signal and to satisfy its fiduciary duties to stockholders,
the Company's Board of Directors must take action to exclude the Purchaser from
the constraints imposed by the Rights Agreement.
 
     Section 203 Condition.  CONSUMMATION OF THE OFFER IS CONDITIONED UPON THE
PURCHASER BEING SATISFIED, IN ITS SOLE DISCRETION, THAT SECTION 203 OF THE
DELAWARE LAW HAS BEEN COMPLIED WITH IN CONNECTION WITH THE PURCHASER'S
ACQUISITION OF THE COMPANY OR IS INVALID OR OTHERWISE INAPPLICABLE TO THE
PURCHASER IN CONNECTION WITH THE OFFER AND THE PROPOSED ROCKWELL MERGER (THE
"SECTION 203 CONDITION").
 
     The Proposed Rockwell Merger, including the timing and details thereof, is
subject to, among other things, the provisions of the Delaware Law, including
Section 203 thereof. In general, Section 203 of the Delaware Law provides that a
Delaware corporation such as the Company may not engage in any "Business
Combination" (defined to include a variety of transactions, including a merger)
with any "Interested Stockholder" (defined generally as a person that directly
or indirectly beneficially owns 15% or more of the corporation's outstanding
voting stock), or any affiliate of an Interested Stockholder, for three years
after the date on which the Interested Stockholder became an Interested
Stockholder, unless (i) prior to the date such Interested Stockholder became an
Interested Stockholder, the board of directors of such corporation approved
either the Business Combination or the transaction which resulted in the
stockholder becoming an Interested Stockholder, (ii) upon consummation of the
transaction which resulted in the stockholder becoming an Interested
Stockholder, the Interested Stockholder owned at least 85% of the voting stock
of the corporation outstanding at the time the transaction commenced (excluding
for purposes of determining the number of shares outstanding those shares held
by persons who are directors and also officers of the corporation and employee
stock plans in which employee participants do not have the right to determine
confidentially whether shares held subject to the plan will be tendered in a
tender or exchange offer) or (iii) on or subsequent to the date the stockholder
becomes an Interested Stockholder, the Business Combination is (a) approved by
the board of directors of the corporation and (b) authorized at an annual or
special meeting of stockholders by the affirmative vote of the holders of at
least 66 2/3% of the outstanding voting stock of the corporation which is not
owned by the Interested Stockholder.
 
     Section 203(b)(6) of the Delaware Law provides that the restrictions
contained in Section 203 of the Delaware Law do not apply to a Business
Combination that is proposed prior to the consummation or abandonment of and
following the announcement or notification of one of certain extraordinary
transactions (including a merger) involving the corporation which transaction
(i) is with or by a person who either was not an Interested Stockholder during
the previous three years or who became an Interested Stockholder with the
approval of the corporation's board of directors and (ii) has been approved or
has not been opposed by a majority of the members of the board of directors then
in office who were directors prior to any person becoming an Interested
Stockholder during the previous three years or were recommended for election or
elected to succeed such directors by a majority of such directors. Accordingly,
the Purchaser believes that, because the General Signal Merger Agreement was
approved by the Board of Directors of the Company, the restrictions on Business
Combinations contained in Section 203 are inapplicable to the Proposed Rockwell
Merger pursuant to Section 203(b)(6).
 
     The Section 203 Condition would be satisfied if the Board of Directors of
the Company approved the Offer and the Proposed Rockwell Merger prior to
consummation of the Offer, or if, upon consummation of the Offer, the Purchaser
owned at least 85% of the total voting stock of the Company outstanding at the
time the
 
                                        5
<PAGE>   9
 
transaction commenced (excluding Shares owned by persons who are directors and
also officers of the Company and possibly excluding Shares held in certain
employee stock plans), or if the Purchaser, in its sole discretion, were
satisfied that Section 203 was invalid or its restrictions were otherwise
inapplicable to the Purchaser in connection with the Proposed Rockwell Merger
for any reason, including, without limitation, those specified in Section 203.
 
     Certain other conditions to the consummation of the Offer are described in
Section 14. The Purchaser expressly reserves the right to waive any one or more
of the conditions to the Offer. See Sections 14 and 15.
 
     THIS OFFER TO PURCHASE AND THE LETTERS OF TRANSMITTAL CONTAIN IMPORTANT
INFORMATION WHICH SHOULD BE READ CAREFULLY BEFORE ANY DECISION IS MADE WITH
RESPECT TO THE OFFER.
 
                                THE TENDER OFFER
 
1.   TERMS OF THE OFFER.  Upon the terms and subject to the conditions of the
Offer (including, if the Offer is extended or amended, the terms and conditions
of any such extension or amendment), the Purchaser will accept for payment and
thereby purchase all Shares validly tendered and not withdrawn in accordance
with the procedures set forth in Section 4 on or prior to the Expiration Date
(as hereinafter defined). The term "Expiration Date" means 12:00 midnight, New
York City time, on Friday, November 18, 1994, unless and until the Purchaser, in
its sole discretion, shall have extended the period of time for which the Offer
is open, in which event the term "Expiration Date" shall mean the time and date
at which the Offer, as so extended by the Purchaser, shall expire.
 
     The Purchaser expressly reserves the right, in its sole discretion, at any
time and from time to time, to extend the period during which the Offer is open
for any reason, including the occurrence of any of the events specified in
Section 14, by giving oral or written notice of such extension to the
Depositary. During any such extension, all Shares previously tendered and not
withdrawn will remain subject to the Offer and subject to the right of a
tendering stockholder to withdraw such stockholder's Shares. See Section 4.
 
     Subject to the applicable regulations of the Securities and Exchange
Commission (the "Commission"), the Purchaser also expressly reserves the right,
in its sole discretion, at any time or from time to time, to (i) delay
acceptance for payment of or, regardless of whether such Shares were theretofore
accepted for payment, payment for any Shares pending receipt of any regulatory
or governmental approvals specified in Section 15, (ii) terminate the Offer
(whether or not any Shares have theretofore been accepted for payment) if any
condition referred to in Section 14 has not been satisfied or upon the
occurrence of any event specified in Section 14 and (iii) waive any condition or
otherwise amend the Offer in any respect, in each case, by giving oral or
written notice of such delay, termination, waiver or amendment to the Depositary
and, other than in the case of any such waiver, by making a public announcement
thereof. The Purchaser acknowledges (i) that Rule 14e-1(c) under the Exchange
Act requires the Purchaser to pay the consideration offered or return the Shares
tendered promptly after the termination or withdrawal of the Offer and (ii) that
the Purchaser may not delay acceptance for payment of, or payment for (except as
provided in clause (i) of the preceding sentence), any Shares upon the
occurrence of any event specified in Section 14 without extending the period of
time during which the Offer is open.
 
     The rights reserved by the Purchaser in the preceding paragraph are in
addition to the Purchaser's rights pursuant to Section 14. Any such extension,
delay, termination or amendment will be followed as promptly as practicable by
public announcement thereof, and such announcement in the case of an extension
will be made no later than 9:00 a.m., New York City time, on the next business
day after the previously scheduled Expiration Date. Without limiting the manner
in which the Purchaser may choose to make any public announcement, subject to
applicable law (including Rules 14d-4(c) and 14d-6(d) under the Exchange Act,
which require that material changes be promptly disseminated to holders of
Shares), the Purchaser shall have no obligation to publish, advertise or
otherwise communicate any such public announcement other than by issuing a
release to the Dow Jones News Service.

<PAGE>   10
 
     If the Purchaser makes a material change in the terms of the Offer, or if
it waives a material condition to the Offer, the Purchaser will extend the Offer
and disseminate additional tender offer materials to the extent required by
Rules 14d-4(c) and 14d-6(d) under the Exchange Act. The minimum period during
which an offer must remain open following material changes in the terms of the
offer, other than a change in price or a change in percentage of securities
sought or a change in any dealer's soliciting fee, will depend upon the facts
and circumstances, including the materiality, of the changes. In the
Commission's view, an offer should remain open for a minimum of five business
days from the date the material change is first published, sent or given to
stockholders, and, if material changes are made with respect to information that
approaches the significance of price and the percentage of securities sought, a
minimum of ten business days may be required to allow for adequate dissemination
and investor response. With respect to a change in price or, subject to certain
limitations, a change in the percentage of securities sought or a change in any
dealer's soliciting fee, a minimum ten business day period from the date of such
change is generally required to allow for adequate dissemination to
stockholders. Accordingly, if prior to the Expiration Date, the Purchaser
decreases the number of Shares being sought, or increases or decreases the
consideration offered pursuant to the Offer, and if the Offer is scheduled to
expire at any time earlier than the period ending on the tenth business day from
the date that notice of such increase or decrease is first published, sent or
given to holders of Shares, the Offer will be extended at least until the
expiration of such ten business day period. For purposes of the Offer, a
"business day" means any day other than a Saturday, Sunday or a federal holiday
and consists of the time period from 12:01 a.m. through 12:00 midnight, New York
City time.
 
     Unless and until the Purchaser declares that the Rights Condition is
satisfied, stockholders will be required to tender one associated Right for each
Share tendered to effect a valid tender of such Share. See Sections 3 and 11.
 
     THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS, THE SATISFACTION OF THE
MINIMUM CONDITION, THE NO IMPEDIMENTS CONDITION, THE RIGHTS CONDITION AND THE
SECTION 203 CONDITION. SEE SECTION 14. The Purchaser reserves the right (but
shall not be obligated), in accordance with applicable rules and regulations of
the Commission, to waive any or all of such conditions. If, by the Expiration
Date, any or all of such conditions have not been satisfied, the Purchaser may,
in its sole discretion, elect to (i) extend the Offer and, subject to applicable
withdrawal rights, retain all tendered Shares until the expiration of the Offer,
as extended, subject to the terms of the Offer, (ii) waive all of the
unsatisfied conditions and, subject to complying with applicable rules and
regulations of the Commission, accept for payment all Shares so tendered and not
extend the Offer or (iii) terminate the Offer and not accept for payment any
Shares and return all tendered Shares to tendering stockholders. In the event
that the Purchaser waives any condition set forth in Section 14, the Commission
may, if the waiver is deemed to constitute a material change to the information
previously provided to the stockholders, require that the Offer remain open for
an additional period of time and/or that the Purchaser disseminate information
concerning such waiver.
 
     A request is being made to the Company pursuant to Rule 14d-5 under the
Exchange Act for the use of the Company's stockholder list, its list of holders
of Rights and security position listings for the purpose of disseminating the
Offer to holders of Shares. Upon compliance by the Company with such request,
this Offer to Purchase and the appropriate related Letter of Transmittal and, if
required, other relevant materials will be mailed to record holders of Shares
and Rights and will be furnished to brokers, dealers, commercial banks, trust
companies and similar persons whose names, or the names of whose nominees,
appear on the stockholder list and list of holders of Rights, if applicable, or
who are listed as participants in a clearing agency's security position listing
for subsequent transmittal to beneficial owners of Shares and Rights.
 
2.   ACCEPTANCE FOR PAYMENT AND PAYMENT.  Upon the terms and subject to the
conditions of the Offer (including, if the Offer is extended or amended, the
terms and conditions of the Offer as so extended or amended), the Purchaser will
purchase, by accepting for payment, and will pay for, all Shares validly
tendered and not withdrawn (as permitted by Section 4) prior to the Expiration
Date promptly after the later to occur of (i) the Expiration Date and (ii) the
satisfaction or waiver of the conditions to the Offer set forth in Section 14.
In addition, subject to applicable rules of the Commission, the Purchaser
expressly reserves the
 
                                        7
<PAGE>   11
 
right to delay acceptance for payment of, or payment for, Shares pending receipt
of any regulatory or governmental approvals specified in Section 15.
 
     For information with respect to approvals required to be obtained prior to
the consummation of the Offer, including under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended (the "HSR Act"), European Community
Regulation 4064/89 (the "EC Merger Regulation") and the Competition Act (Canada)
(the "Competition Act"), see Section 15.
 
     In all cases, payment for Shares purchased pursuant to the Offer will be
made only after timely receipt by the Depositary of (i) Share Certificates for
such Shares and, if applicable, Rights Certificates for the associated Rights,
or, in the case of Class A Shares, timely confirmation (a "Book-Entry
Confirmation") of the book-entry transfer of such Shares and, if applicable,
Rights into the Depositary's account at The Depository Trust Company, Midwest
Securities Trust Company or Philadelphia Depository Trust Company (collectively,
the "Book-Entry Transfer Facilities") pursuant to the procedures set forth in
Section 3, (ii) the appropriate Letter of Transmittal (or a facsimile thereof),
properly completed and duly executed, with any required signature guarantees,
or, in the case of Class A Shares, an Agent's Message (as defined below) in
connection with a book-entry transfer and (iii) any other documents required by
the appropriate Letter of Transmittal.
 
     The term "Agent's Message" means a message transmitted by a Book-Entry
Transfer Facility to, and received by, the Depositary and forming a part of a
Book-Entry Confirmation, which states that such Book-Entry Transfer Facility has
received an express acknowledgment from the participant in such Book-Entry
Transfer Facility tendering the Class A Shares and, if applicable, the Class A
Rights which are the subject of such Book-Entry Confirmation that such
participant has received and agrees to be bound by the terms of the appropriate
Letter of Transmittal and that the Purchaser may enforce such agreement against
such participant.
 
     For purposes of the Offer, the Purchaser will be deemed to have accepted
for payment, and thereby purchased, Shares validly tendered and not withdrawn
as, if and when the Purchaser gives oral or written notice to the Depositary of
the Purchaser's acceptance of such Shares for payment pursuant to the Offer. In
all cases, upon the terms and subject to the conditions of the Offer, payment
for Shares purchased pursuant to the Offer will be made by deposit of the
purchase price therefor with the Depositary, which will act as agent for
tendering stockholders for the purpose of receiving payment from the Purchaser
and transmitting payment to validly tendering stockholders. UNDER NO
CIRCUMSTANCES WILL INTEREST ON THE PURCHASE PRICE FOR SHARES BE PAID BY THE
PURCHASER.
 
     If any tendered Shares are not purchased pursuant to the Offer for any
reason, or if Share Certificates are submitted representing more Shares than are
tendered, Share Certificates representing unpurchased or untendered Shares will
be returned, without expense to the tendering stockholder (or, in the case of
Class A Shares delivered by book-entry transfer into the Depositary's account at
a Book-Entry Transfer Facility pursuant to the procedures set forth in Section
3, such Shares will be credited to an account maintained within such Book-Entry
Transfer Facility), as promptly as practicable following the expiration,
termination or withdrawal of the Offer. In the event separate Rights
Certificates are issued, similar action will be taken with respect to
unpurchased and untendered Rights.
 
     IF, PRIOR TO THE EXPIRATION DATE, THE PURCHASER SHALL INCREASE THE
CONSIDERATION OFFERED TO HOLDERS OF SHARES PURSUANT TO THE OFFER, SUCH INCREASED
CONSIDERATION SHALL BE PAID TO ALL HOLDERS OF SHARES THAT ARE PURCHASED PURSUANT
TO THE OFFER, WHETHER OR NOT SUCH SHARES WERE TENDERED PRIOR TO SUCH INCREASE IN
CONSIDERATION.
 
     The Purchaser reserves the right to transfer or assign, in whole or from
time to time in part, to one or more of the Purchaser's subsidiaries or
affiliates the right to purchase all or any portion of the Shares and Rights
tendered pursuant to the Offer, but any such transfer or assignment will not
relieve the Purchaser of its obligations under the Offer or prejudice the rights
of tendering stockholders to receive payment for Shares validly tendered and
accepted for payment pursuant to the Offer.

3.   PROCEDURES FOR ACCEPTING THE OFFER AND TENDERING SHARES AND RIGHTS.
 
VALID TENDER OF SHARES AND RIGHTS
 
     Except as set forth below, in order for Shares and (prior to the
Distribution Date) Rights to be validly tendered pursuant to the Offer, the
appropriate Letter of Transmittal (or a facsimile thereof), properly completed
and duly executed, together with any required signature guarantees, or, in the
case of Class A Shares, an Agent's Message in connection with a book-entry
delivery of Class A Shares and (prior to the Distribution Date) Class A Rights,
and any other documents required by the appropriate Letter of Transmittal must
be received by the Depositary at one of its addresses set forth on the back
cover of this Offer to Purchase on or prior to the Expiration Date and either
(i) Share Certificates and, if applicable, Rights Certificates representing
tendered Shares and Rights must be received by the Depositary, or, in the case
of Class A Shares, such Class A Shares and Class A Rights must be tendered
pursuant to the procedure for book-entry transfer set forth below and Book-Entry
Confirmation must be received by the Depositary, in each case on or prior to the
Expiration Date, or (ii) the guaranteed delivery procedures set forth below must
be complied with.
 
     A Class A Letter of Transmittal should be used to tender Class A Shares, a
Class B Letter of Transmittal should be used to tender Class B Shares and a
Class C Letter of Transmittal should be used to tender Class C Shares.
 
     IF THE PURCHASER DECLARES THAT THE RIGHTS CONDITION IS SATISFIED, THE
PURCHASER WILL NOT REQUIRE DELIVERY OF RIGHTS. UNLESS AND UNTIL THE PURCHASER
DECLARES THAT THE RIGHTS CONDITION IS SATISFIED, HOLDERS OF SHARES WILL BE
REQUIRED TO TENDER ONE ASSOCIATED RIGHT FOR EACH SHARE TENDERED IN ORDER TO
EFFECT A VALID TENDER OF SUCH SHARE.
 
     THE METHOD OF DELIVERY OF SHARE CERTIFICATES, RIGHTS CERTIFICATES (IF
APPLICABLE), THE APPROPRIATE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE OPTION AND SOLE RISK OF THE TENDERING STOCKHOLDER, AND THE
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE DEPOSITARY. IF
DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY
INSURED, IS RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO
ENSURE TIMELY DELIVERY.
 
SEPARATE DELIVERY OF RIGHTS CERTIFICATES
 
     If the Distribution Date does not occur prior to the Expiration Date, a
tender of Shares will also constitute a tender of the associated Rights. If the
Distribution Date occurs and Rights Certificates are distributed by the Company
to holders of Shares prior to the time a holder's Shares are tendered pursuant
to the Offer, in order for Rights (and the corresponding Shares) to be validly
tendered, Rights Certificates representing a number (and the series) of Rights
equal to the number (and class) of Shares tendered must be delivered to the
Depositary or, if available in the case of Class A Rights, a Book-Entry
Confirmation received by the Depositary with respect thereto. If the
Distribution Date occurs and Rights Certificates are not distributed prior to
the time Shares are tendered pursuant to the Offer, Rights may be tendered prior
to a stockholder receiving Rights Certificates by use of the guaranteed delivery
procedure described below. In any case, a tender of Shares constitutes an
agreement by the tendering stockholder to deliver Rights Certificates
representing a number (and the series) of Rights equal to the number (and class)
of Shares tendered pursuant to the Offer to the Depositary within five business
days after the date Rights Certificates are distributed. The Purchaser reserves
the right to require that the Depositary receive Rights Certificates, or a
Book-Entry Confirmation, if available in the case of Class A Rights, with
respect to such Rights, prior to accepting the related Shares for payment
pursuant to the Offer if the Distribution Date occurs prior to the Expiration
Date.
 
BOOK-ENTRY TRANSFER
 
     The Depositary will make a request to establish accounts with respect to
the Class A Shares at each of the Book-Entry Transfer Facilities for purposes of
the Offer within two business days after the date of this
 
                                        9
<PAGE>   13
 
Offer to Purchase. Any financial institution that is a participant in the system
of any Book-Entry Transfer Facility may make Book-Entry delivery of Class A
Shares by causing such Book-Entry Transfer Facility to transfer such Class A
Shares into the Depositary's account at such Book-Entry Transfer Facility in
accordance with such Book-Entry Transfer Facility's procedures for such
transfer. However, although delivery of Class A Shares may be effected through
book-entry transfer into the Depositary's account at a Book-Entry Transfer
Facility, the appropriate Letter of Transmittal (or facsimile thereof), properly
completed and duly executed, with any required signature guarantees, or an
Agent's Message in connection with a book-entry transfer, and any other required
documents must, in any case, be transmitted to and received by the Depositary at
one of its addresses set forth on the back cover of this Offer to Purchase on or
prior to the Expiration Date, or the guaranteed delivery procedure set forth
below must be complied with.
 
     If the Distribution Date occurs, the Depositary will also make a request to
establish an account with respect to the Class A Rights at each of the
Book-Entry Transfer Facilities, but no assurance can be given that book-entry
delivery of Class A Rights will be available. If book-entry delivery of Class A
Rights is available, the foregoing book-entry transfer procedures will also
apply to Class A Rights. Otherwise, if Rights Certificates have been issued, a
tendering stockholder will be required to tender Rights by means of physical
delivery to the Depositary of Rights Certificates (in which event references in
this Offer to Purchase to Book-Entry Confirmations with respect to Class A
Rights will be inapplicable) or pursuant to the guaranteed delivery procedure
set forth below.
 
     DELIVERY OF DOCUMENTS TO A BOOK-ENTRY TRANSFER FACILITY IN ACCORDANCE WITH
SUCH BOOK-ENTRY TRANSFER FACILITY'S PROCEDURES DOES NOT CONSTITUTE DELIVERY TO
THE DEPOSITARY.
 
SIGNATURE GUARANTEES
 
     Signatures on all Letters of Transmittal must be guaranteed by a firm that
is a bank, broker, dealer, credit union, savings association or other entity
which is a member in good standing of the Securities Transfer Agents Medallion
Program (an "Eligible Institution"), unless the Shares and Rights tendered
thereby are tendered (i) by a registered holder of Shares and Rights who has not
completed either the box labeled "Special Payment Instructions" or the box
labeled "Special Delivery Instructions" on the appropriate Letter of Transmittal
or (ii) for the account of an Eligible Institution. See Instruction 1 of the
appropriate Letter of Transmittal.
 
     If the Share Certificates or Rights Certificates are registered in the name
of a person other than the signer of the Letter of Transmittal, or if payment is
to be made to, or Share Certificates or Rights Certificates for unpurchased
Shares or Rights are to be issued or returned to, a person other than the
registered holder, then the tendered certificates must be endorsed or
accompanied by appropriate stock powers, signed exactly as the name or names of
the registered holder or holders appear on the certificates, with the signatures
on the certificates or stock powers guaranteed by an Eligible Institution as
provided in the appropriate Letter of Transmittal. See Instructions 1 and 5 of
the appropriate Letter of Transmittal.
 
     If the Share Certificates and Rights Certificates are forwarded separately
to the Depositary, a properly completed and duly executed appropriate Letter of
Transmittal (or facsimile thereof) must accompany each such delivery.
 
GUARANTEED DELIVERY
 
     If a stockholder desires to tender Shares and Rights pursuant to the Offer
and such stockholder's Share Certificates or, if applicable, Rights Certificates
are not immediately available (including, if the Distribution Date has occurred,
because Rights Certificates have not yet been distributed by the Company) or
time will not permit all required documents to reach the Depositary on or prior
to the Expiration Date, or, in the case of Class A Shares, the procedures for
book-entry transfer cannot be completed on a timely basis, such Shares or
 
                                       10
<PAGE>   14
 
Rights may nevertheless be tendered if all of the following guaranteed delivery
procedures are duly complied with:
 
          (i) such tender is made by or through an Eligible Institution;
 
          (ii) a properly completed and duly executed Notice of Guaranteed
     Delivery, substantially in the form made available by the Purchaser, is
     received by the Depositary, as provided below, on or prior to the
     Expiration Date; and
 
          (iii) the Share Certificates and Rights Certificates (or, in the case
     of Class A Shares and, if available, Class A Rights, a Book-Entry
     Confirmation) representing all tendered Shares and Rights, in proper form
     for transfer together with a properly completed and duly executed
     appropriate Letter of Transmittal (or facsimile thereof), with any required
     signature guarantees (or, in the case of a book-entry transfer of Class A
     Shares and, if available, Class A Rights, an Agent's Message) and any other
     documents required by the appropriate Letter of Transmittal are received by
     the Depositary within (x) in the case of Shares, five New York Stock
     Exchange, Inc. ("NYSE") trading days after the date of execution of such
     Notice of Guaranteed Delivery or (y) in the case of Rights, a period ending
     on the later of (1) five NYSE trading days after the date of execution of
     such Notice of Guaranteed Delivery and (2) five business days after the
     date Rights Certificates are distributed to stockholders by the Company.
 
     The Notice of Guaranteed Delivery may be delivered by hand or mail or
transmitted by facsimile transmission to the Depositary and must include a
guarantee by an Eligible Institution in the form set forth in such Notice of
Guaranteed Delivery and a representation that the stockholder on whose behalf
the tender is being made is deemed to own the Shares and, if applicable, Rights
being tendered within the meaning of Rule 14e-4 under the Exchange Act.
 
     Notwithstanding any other provision hereof, payment for Shares accepted for
payment pursuant to the Offer will in all cases be made only after timely
receipt by the Depositary of Share Certificates for, or, in the case of Class A
Shares, of Book-Entry Confirmation with respect to, such Shares, and if the
Distribution Date has occurred, Rights Certificates for, or, in the case of
Class A Rights, a Book-Entry Confirmation, if available, with respect to, the
associated Rights (unless the Purchaser elects, in its sole discretion, to make
payment for such Shares pending receipt of the Rights Certificates for, or, in
the case of Class A Rights, a Book-Entry Confirmation, if available, with
respect to, such Rights), a properly completed and duly executed appropriate
Letter of Transmittal (or facsimile thereof), together with any required
signature guarantees (or, in the case of a book-entry transfer of Class A Shares
or, if available, Class A Rights, an Agent's Message) and any other documents
required by the appropriate Letter of Transmittal. Accordingly, payment might
not be made to all tendering stockholders at the same time, and will depend upon
when Share Certificates (or Rights Certificates) are received by the Depositary
or, in the case of Class A Shares or Class A Rights, Book-Entry Confirmations of
such Shares (or Rights, if available) are received into the Depositary's account
at a Book-Entry Transfer Facility.
 
     If the Rights Condition is satisfied, the guaranteed delivery procedure
with respect to Rights Certificates and the requirement for the tender of Rights
will no longer apply.
 
BACKUP FEDERAL INCOME TAX WITHHOLDING
 
     UNDER THE BACKUP FEDERAL INCOME TAX LAWS APPLICABLE TO CERTAIN STOCKHOLDERS
(OTHER THAN CERTAIN EXEMPT STOCKHOLDERS, INCLUDING, AMONG OTHERS, ALL
CORPORATIONS AND CERTAIN FOREIGN INDIVIDUALS), THE DEPOSITARY MAY BE REQUIRED TO
WITHHOLD 31% OF THE AMOUNT OF ANY PAYMENTS MADE TO SUCH STOCKHOLDERS PURSUANT TO
THE OFFER OR THE PROPOSED ROCKWELL MERGER. TO PREVENT BACKUP FEDERAL INCOME TAX
WITHHOLDING, EACH SUCH STOCKHOLDER MUST PROVIDE THE DEPOSITARY WITH SUCH
STOCKHOLDER'S CORRECT TAXPAYER IDENTIFICATION NUMBER AND CERTIFY THAT SUCH
STOCKHOLDER IS NOT SUBJECT TO BACKUP FEDERAL INCOME TAX WITHHOLDING BY

COMPLETING THE SUBSTITUTE FORM W-9 INCLUDED IN THE LETTERS OF TRANSMITTAL. SEE
INSTRUCTION 9 OF THE LETTERS OF TRANSMITTAL.
 
CONVERSION OF CLASS B SHARES AND CLASS C SHARES INTO CLASS A SHARES
 
     By executing the appropriate Letter of Transmittal, a tendering holder of
Class B Shares or Class C Shares irrevocably appoints the Depositary as such
holder's agent, attorney-in-fact and proxy to present all Class B Shares or
Class C Shares tendered by such holder and accepted for payment and paid for by
the Purchaser, together with any required notice, for conversion, on behalf of
the holder, into Class A Shares and then to transfer to the Purchaser the Class
A Shares into which such Class B Shares or Class C Shares were converted.
 
APPOINTMENT AS PROXY
 
     By executing the appropriate Letter of Transmittal, a tendering stockholder
irrevocably appoints designees of the Purchaser, and each of them, as such
stockholder's attorneys-in-fact and proxies, with full power of substitution, in
the manner set forth in the Letters of Transmittal, to the full extent of such
stockholder's rights with respect to the Shares and, if applicable, Rights
tendered by such stockholder and accepted for payment by the Purchaser and with
respect to any and all other Shares or Rights and other securities or rights
issued or issuable in respect of such Shares and Rights on or after the date of
this Offer to Purchase. All such powers of attorney and proxies shall be
considered irrevocable and coupled with an interest in the tendered Shares and
Rights. Such appointment will be effective upon the acceptance for payment of
such Shares and Rights by the Purchaser in accordance with the terms of the
Offer. Upon such acceptance for payment, all other powers of attorney and
proxies given by such stockholder with respect to such Shares, Rights, and such
other securities or rights prior to such payment will be revoked, without
further action, and no subsequent powers of attorney and proxies may be given by
such stockholder (and, if given, will not be deemed effective). The designees of
the Purchaser will, with respect to the Shares and Rights and such other
securities and rights for which such appointment is effective, be empowered to
exercise all voting and other rights of such stockholder as they in their sole
discretion may deem proper at any annual or special meeting of the Company's
stockholders, or any adjournment or postponement thereof, or by consent in lieu
of any such meeting or otherwise. In order for Shares and Rights to be deemed
validly tendered, immediately upon the acceptance for payment of such Shares and
Rights, the Purchaser or its designee must be able to exercise full voting
rights with respect to such Shares, Rights and other securities, including
voting at any meeting of stockholders.
 
DETERMINATION OF VALIDITY
 
     All questions as to the form of documents and the validity, eligibility
(including time of receipt) and acceptance for payment of any tender of Shares
or Rights will be determined by the Purchaser, in its sole discretion, whose
determination shall be final and binding on all parties. The Purchaser reserves
the absolute right to reject any or all tenders determined by it not to be in
proper form or the acceptance of or payment for which may, in the opinion of the
Purchaser's counsel, be unlawful. The Purchaser also reserves the absolute right
to waive any of the conditions of the Offer or any defect or irregularity in any
tender of Shares or Rights of any particular stockholder whether or not similar
defects or irregularities are waived in the case of other stockholders.
 
     The Purchaser's interpretation of the terms and conditions of the Offer
(including the Letters of Transmittal and the instructions thereto) will be
final and binding. No tender of Shares or Rights will be deemed to have been
validly made until all defects and irregularities with respect to such tender
have been cured or waived by the Purchaser. None of Rockwell, the Purchaser or
any of their respective affiliates or assigns, the Dealer Manager, the
Depositary, the Information Agent or any other person or entity will be under
any duty to give any notification of any defects or irregularities in tenders or
incur any liability for failure to give any such notification.
 
                                       12
<PAGE>   16
 
     The Purchaser's acceptance for payment of Shares and, if applicable, Rights
tendered pursuant to any of the procedures described above will constitute a
binding agreement between the tendering stockholder and the Purchaser upon the
terms and subject to the conditions of the Offer.
 
4.   WITHDRAWAL RIGHTS.  Except as otherwise provided in this Section 4, tenders
of Shares and Rights made pursuant to the Offer are irrevocable. Shares and
Rights tendered pursuant to the Offer may be withdrawn at any time on or prior
to the Expiration Date and, unless theretofore accepted for payment as provided
herein, may also be withdrawn at any time after December 19, 1994 (or such later
date as may apply in case the Offer is extended). A withdrawal of Shares will
also constitute a withdrawal of the associated Rights. Rights may not be
withdrawn unless the associated Shares are also withdrawn.
 
     If, for any reason whatsoever, acceptance for payment of any Shares and
Rights tendered pursuant to the Offer is delayed, or the Purchaser is unable to
accept for payment or pay for Shares and Rights tendered pursuant to the Offer,
then, without prejudice to the Purchaser's rights set forth herein, the
Depositary may, nevertheless, on behalf of the Purchaser, retain tendered Shares
and Rights and such Shares and Rights may not be withdrawn except to the extent
that the tendering stockholder is entitled to and duly exercises withdrawal
rights as described in this Section 4. Any such delay will be by an extension of
the Offer to the extent required by law.
 
     In order for a withdrawal to be effective, a written or facsimile
transmission notice of withdrawal must be timely received by the Depositary at
one of its addresses set forth on the back cover of this Offer to Purchase. Any
such notice of withdrawal must specify the name of the person who tendered the
Shares and Rights to be withdrawn, the number of Shares and Rights to be
withdrawn, and (if Share Certificates and Rights Certificates have been
tendered) the name of the registered holder of the Shares and Rights as set
forth in the Share Certificate and Rights Certificate, if different from that of
the person who tendered such Shares and Rights. If Share Certificates and Rights
Certificates have been delivered or otherwise identified to the Depositary, then
prior to the physical release of such certificates, the tendering stockholder
must submit the serial numbers shown on the particular certificates evidencing
the Shares and Rights to be withdrawn and the signature on the notice of
withdrawal must be guaranteed by an Eligible Institution, except in the case of
Shares and Rights tendered for the account of an Eligible Institution. If Class
A Shares and Class A Rights have been tendered pursuant to the procedures for
book-entry transfer set forth in Section 3, the notice of withdrawal must
specify the name and number of the account at the appropriate Book-Entry
Transfer Facility to be credited with the withdrawn Class A Shares and Class A
Rights, in which case a notice of withdrawal will be effective if delivered to
the Depositary by any method of delivery described in the first sentence of this
paragraph. Withdrawals of Shares and Rights may not be rescinded. Any Shares and
Rights properly withdrawn will be deemed not validly tendered for purposes of
the Offer, but may be retendered at any subsequent time prior to the Expiration
Date by following any of the procedures described in Section 3.
 
     All questions as to the form and validity (including time of receipt) of
notices of withdrawal will be determined by the Purchaser, in its sole
discretion, whose determination shall be final and binding. None of Rockwell,
the Purchaser or any of their respective affiliates or assigns, the Dealer
Manager, the Depositary, the Information Agent or any other person or entity
will be under any duty to give any notification of any defects or irregularities
in any notice of withdrawal or incur any liability for failure to give any such
notification.
 
5.   CERTAIN TAX CONSEQUENCES.  The receipt of cash for Shares pursuant to the
Offer or the Proposed Rockwell Merger will be a taxable transaction for federal
income tax purposes and may also be a taxable transaction under applicable
state, local, foreign and other tax laws. For federal income tax purposes, each
selling or exchanging stockholder would generally recognize gain or loss equal
to the difference between the amount of cash received and such stockholder's tax
basis for the sold or exchanged Shares. Such gain or loss will be capital gain
or loss (assuming the Shares are held as a capital asset) and any such capital
gain or loss will be long term if, as of the date of sale or exchange, the
Shares were held for more than one year or will be short term if, as of such
date, the Shares were held for one year or less.
 
     The foregoing discussion may not be applicable to certain types of
stockholders, including stockholders who acquired Shares pursuant to the
exercise of employee stock options or otherwise as compensation,
 
                                       13
<PAGE>   17
 
individuals who are not citizens or residents of the United States and foreign
corporations, or entities that are otherwise subject to special tax treatment
under the Internal Revenue Code of 1986, as amended (such as insurance
companies, tax-exempt entities and regulated investment companies).
 
     THE FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE IS INCLUDED FOR GENERAL
INFORMATION ONLY. EACH STOCKHOLDER IS URGED TO CONSULT SUCH STOCKHOLDER'S TAX
ADVISOR WITH RESPECT TO THE TAX CONSEQUENCES TO SUCH STOCKHOLDER OF THE OFFER
AND PROPOSED ROCKWELL MERGER, INCLUDING FEDERAL, STATE AND LOCAL TAX
CONSEQUENCES.
 
6.   PRICE RANGE OF THE SHARES; DIVIDENDS.  According to the Company's 1993
Annual Report, the Class A Shares are listed and traded on the NYSE and have
been so listed and traded since May 6, 1992. The Class A Shares are traded on
the NYSE under the symbol "REE." The following table sets forth, for the periods
indicated, the reported high and low sale prices for the Class A Shares on the
NYSE Composite Tape and the amount of cash dividends paid per Class A Share, as
reported in the Company's 1993 Annual Report with respect to periods occurring
in 1992 and 1993, and as reported thereafter by published financial sources,
with respect to periods occurring in 1994.

     According to the Company's 1993 Annual Report, there is no public trading
market for the Class B Shares and the Class C Shares and, at December 31, 1993,
there were eleven stockholders of record and one stockholder of record for the
Class B Shares and the Class C Shares, respectively. According to the Company
Certificate of Incorporation and other publicly available information, each
Class B Share may be converted into one Class A Share and each Class C Share may
be converted into 2.708 Class A Shares upon the satisfaction of certain
conditions. According to the Company Certificate of Incorporation, holders of
Class C Shares are entitled to convert Class C Shares into Class A Shares, inter
alia, in connection with the Company's merger into, consolidation with or
acquisition by, another entity or to the extent such holder intends to tender
Class A Shares upon conversion of Class C Shares, upon the commencement of any
tender offer made to all holders of the Company's voting common stock for at
least a majority of the Company's outstanding voting common stock.
 
     On August 29, 1994, the last full day of trading prior to the announcement
of the execution of the General Signal Merger Agreement, according to published
sources, the reported closing price on the NYSE Composite Tape for the Class A
Shares was $19 7/8 per Class A Share. On October 19, 1994, the last full day of
trading prior to the announcement of the Offer, according to published sources,
the reported closing price on
 
                                       14
<PAGE>   18
 
the NYSE Composite Tape for the Class A Shares was $24 1/2 per Class A Share.
STOCKHOLDERS ARE URGED TO OBTAIN A CURRENT MARKET QUOTATION FOR THE CLASS A
SHARES.
 
     The Purchaser believes, based upon publicly available information, that as
of the date of this Offer to Purchase, the Class A Rights are listed on the NYSE
and all Rights are attached to the associated Shares and are not traded
separately. As a result, the sale prices per Class A Share set forth above are
also the high and low sale prices per Class A Share and associated Class A Right
during all such periods after September 15, 1994, the date of issuance of the
Class A Rights. Upon the occurrence of the Distribution Date, the Rights are to
detach, and may trade separately, from the Shares. See Section 11. As a result
of the announcement by the Purchaser of the Offer, the Distribution Date will be
November 3, 1994, unless prior to such date the Company's Board of Directors
redeems the Rights or takes action to delay the Distribution Date. The
Distribution Date may also occur sooner. See Section 11. IF THE DISTRIBUTION
DATE OCCURS AND THE CLASS A RIGHTS BEGIN TO TRADE SEPARATELY FROM THE CLASS A
SHARES, STOCKHOLDERS ARE ALSO URGED TO OBTAIN A CURRENT MARKET QUOTATION FOR THE
CLASS A RIGHTS.
 
7.   POSSIBLE EFFECTS OF THE OFFER ON THE MARKET FOR THE SHARES; STOCK EXCHANGE
LISTING; EXCHANGE ACT REGISTRATION; MARGIN REGULATIONS.
 
POSSIBLE EFFECTS OF THE OFFER ON THE MARKET FOR THE SHARES
 
     The purchase of Class A Shares pursuant to the Offer will reduce the number
of Class A Shares that might otherwise trade publicly and could adversely affect
the liquidity and market value of the remaining Class A Shares held by the
public. The purchase of Class A Shares pursuant to the Offer can also be
expected to reduce the number of holders of Class A Shares. The Purchaser cannot
predict whether the reduction in the number of Class A Shares that might
otherwise trade publicly would have an adverse or beneficial effect on the
market price for or marketability of the Class A Shares or whether it would
cause future market prices to be greater or less than the Offer price therefor.
 
STOCK EXCHANGE LISTING
 
     According to the NYSE's published guidelines, the NYSE would consider
delisting the Class A Shares if, among other things, the number of record
holders of at least 100 Class A Shares should fall below 1,200, the number of
publicly held Class A Shares (exclusive of holdings of officers, directors,
their immediate families and other concentrated holdings of 10% or more ("NYSE
Excluded Holdings")) should fall below 600,000 or the aggregate market value of
publicly held Class A Shares (exclusive of NYSE Excluded Holdings) should fall
below $5,000,000.
 
     Depending upon the number of Class A Shares acquired pursuant to the Offer,
the Class A Shares may no longer meet the requirements for continued listing on
the NYSE. If as a result of the purchase of Class A Shares pursuant to the
Offer, Class A Shares no longer meet the requirements of the NYSE for continued
listing and the listing of the Class A Shares is discontinued, the market for
the Class A Shares could be adversely affected.
 
     In the event that the Class A Shares were no longer listed or traded on the
NYSE, it is possible that the Class A Shares would trade on another securities
exchange or in the over-the-counter market and that price quotations would be
reported by such exchange, through the National Association of Securities
Dealers Automated Quotation System ("NASDAQ") or other sources. Such trading and
the availability of such quotations would, however, depend upon the number of
stockholders and/or the aggregate market value of the Class A Shares remaining
at such time, the interest in maintaining a market in the Class A Shares on the
part of securities firms, the possible termination of registration of the Class
A Shares under the Exchange Act as described below and other factors.
 
EXCHANGE ACT REGISTRATION
 
     The Class A Shares are currently registered under the Exchange Act. The
purchase of the Class A Shares pursuant to the Offer may result in the Class A
Shares becoming eligible for deregistration under the
 
                                       15
<PAGE>   19
 
Exchange Act. Registration of the Class A Shares may be terminated upon
application by the Company to the Commission if the Class A Shares are not
listed on a "national securities exchange" and there are fewer than 300 record
holders of Class A Shares. Termination of registration of the Class A Shares
under the Exchange Act would substantially reduce the information required to be
furnished by the Company to its stockholders and the Commission and would make
certain provisions of the Exchange Act, such as the short-swing profit recovery
provisions of Section 16(b) and the requirements of furnishing a proxy statement
in connection with stockholders' meetings pursuant to Section 14(a) or 14(c) and
the related requirement of an annual report, no longer applicable to the
Company. If the Class A Shares are no longer registered under the Exchange Act,
the requirements of Rule 13e-3 under the Exchange Act with respect to "going
private" transactions would no longer be applicable to the Company. Furthermore,
the ability of "affiliates" of the Company and persons holding "restricted
securities" of the Company to dispose of such securities pursuant to Rule 144
promulgated under the Securities Act of 1933, as amended, may be impaired or,
with respect to certain persons, eliminated. If registration of the Class A
Shares under the Exchange Act were terminated, the Class A Shares would no
longer be "margin securities" or eligible for stock exchange listing or NASDAQ
reporting. The Purchaser believes that the purchase of the Class A Shares
pursuant to the Offer may result in the Class A Shares becoming eligible for
deregistration under the Exchange Act and it would be the intention of the
Purchaser to cause the Company to make an application for termination of
registration of the Class A Shares as soon as possible after successful
completion of the Offer, if the Class A Shares are then eligible for such
termination.
 
     Based upon publicly available information, the Purchaser believes that, as
of the date of this Offer to Purchase, the Class A Rights are registered under
the Exchange Act and are listed on the NYSE, but are attached to the Class A
Shares and are not separately transferable. As a result of the announcement by
the Purchaser of the Offer, the Distribution Date will be November 3, 1994
unless, prior to such date, the Company's Board of Directors redeems the Rights
or takes action to delay the Distribution Date. The Distribution Date may also
occur sooner. See Section 11. According to the Company 8-A, as soon as
practicable after the occurrence of the Distribution Date, Rights Certificates
will be sent to all holders of Rights and Rights will become transferable apart
from the Shares. See Section 11. If the Distribution Date occurs and the Rights
separate from the Shares, the foregoing discussion with respect to the effect of
the Offer on the market for the Class A Shares, stock exchange listings and
Exchange Act registration would apply to the Class A Rights in a similar manner.
 
     If registration of the Class A Shares and the Class A Rights is not
terminated prior to the Proposed Rockwell Merger, then the Class A Shares and
the Class A Rights will be delisted from the NYSE and the registration of the
Class A Shares and the Class A Rights under the Exchange Act will be terminated
following the consummation of the Proposed Rockwell Merger.
 
MARGIN REGULATIONS
 
     The Class A Shares are currently "margin securities" under the regulations
of the Board of Governors of the Federal Reserve System (the "Federal Reserve
Board"), which have the effect, among other things, of allowing brokers to
extend credit on the collateral of such Class A Shares for the purpose of
buying, carrying or trading in securities ("Purpose Loans"). Depending upon
factors such as the number of record holders of the Class A Shares and the
number and market value of publicly held Class A Shares, following the purchase
of Class A Shares pursuant to the Offer, the Class A Shares might no longer
constitute "margin securities" for purposes of the Federal Reserve Board's
margin regulations and, therefore, could no longer be used as collateral for
Purpose Loans made by brokers. In addition, if registration of the Class A
Shares under the Exchange Act were terminated, the Class A Shares would no
longer constitute "margin securities."

  $4.62 per share.
 
     Except as set forth elsewhere in this Offer to Purchase: (i) neither
Rockwell nor the Purchaser nor, to the knowledge of Rockwell or the Purchaser,
any of the persons listed in Schedule I hereto or any associate or
majority-owned subsidiary of Rockwell or the Purchaser or any of the persons so
listed, beneficially owns or has a right to acquire any Shares or any other
equity securities of the Company; (ii) neither Rockwell nor the Purchaser nor,

<PAGE>   25
 
Purchaser nor, to the knowledge of Rockwell or the Purchaser, any of the persons
listed in Schedule I hereto, has any contract, arrangement, understanding or
relationship with any other person with respect to any securities of the Company
(including, but not limited to, any contract, arrangement, understanding or
relationship concerning the transfer or the voting of any such securities, joint
ventures, loan or option arrangements, puts or calls, guaranties of loans,
guaranties against loss or the giving or withholding of proxies, consents or
authorizations); (iv) since January 1, 1991, there have been no transactions
which would require reporting under the rules and regulations of the Commission
between Rockwell or the Purchaser or any of their respective subsidiaries or, to
the knowledge of Rockwell or the Purchaser, any of the persons listed in
Schedule I hereto, on the one hand, and the Company or any of its executive
officers, directors or affiliates, on the other hand; and (v) since January 1,
1991, there have been no contacts, negotiations or transactions between Rockwell
or the Purchaser or any of their respective subsidiaries or, to the knowledge of
Rockwell or the Purchaser, any of the persons listed in Schedule I hereto, on
the one hand, and the Company or any of its subsidiaries or affiliates, on the
other hand, concerning a merger, consolidation or acquisition, a tender offer or

     On October 14, 1994, the Purchaser purchased 100 Class A Shares at a price
of $24.75 per Class A Share. Such purchase was effected on the NYSE in an open
market transaction. Such 100 Class A Shares represent less than one
one-thousandth of one percent of the outstanding Class A Shares on a fully
diluted basis.
 
10. BACKGROUND OF THE OFFER; CONTACTS WITH THE COMPANY.  In the summer of 1991,
the Company explored with Rockwell a sale of the Company. In connection
therewith, Rockwell and the Company entered into an agreement dated August 13,
1991 which provided, among other things, that Rockwell would not, for a period
of two years from the date of such agreement (until August 13, 1993), engage in
certain actions involving the Company, including actions such as those
contemplated by the Offer and the Proposed Rockwell Merger. After reviewing
certain preliminary information provided by the Company, in late September 1991
Rockwell terminated activities in connection with its consideration of a
possible acquisition of the Company.
 
     Beginning in 1992, Rockwell, through its wholly-owned subsidiary
Allen-Bradley, began discussing and developing various cooperative activities
between Allen-Bradley and the Company, including joint development of new
products and reciprocal product branding. In the course of such activities on
October 27, 1993, John C. Morley, President and Chief Executive Officer of the
Company, met with Don H. Davis, Jr., at that time President of Allen-Bradley,
and appeared to be inviting Rockwell to "go beyond" their existing cooperative
efforts. On May 12, 1994, Mr. Davis, who then was Executive Vice President and
Chief Operating Officer of Rockwell, advised Mr. Morley that Rockwell was
interested in acquiring the Company. On July 12, 1994, Mr. Davis and Donald R.
Beall, Chairman of the Board and Chief Executive Officer of Rockwell, met with
Mr. Morley. At that time Mr. Beall informed Mr. Morley that Rockwell was
extremely interested in acquiring the Company. Mr. Morley said that he would
raise the matter with the Company's Board of Directors and would respond
promptly. On August 11, 1994, Mr. Morley advised Mr. Davis that he had discussed
Rockwell's interest in a proposed acquisition of the Company with the Company's
Board of Directors, but that he could not give Rockwell a definitive response at
that time.
 
     According to the Company 8-A, on August 29, 1994, the Board of Directors of
the Company declared a dividend distribution of one Right for each outstanding
Class A Share, Class B Share and Class C Share to purchase one one-hundredth of
a share of a new Series A, Series B or Series C Preferred Stock, respectively,
pursuant to the Rights Agreement. See Section 11 for a description of the
Rights.
 
     On August 30, 1994, the Company announced that it had entered into the
General Signal Merger Agreement. The General Signal Merger Agreement provides,
subject to the conditions set forth therein (including approval by the
stockholders of General Signal and the Company), for the Proposed General Signal
Merger in which each Class A Share would be converted into the right to receive
0.739 of one share of General Signal Common Stock, each Class B Share would be
converted into the right to receive 0.739 of one share of General Signal Class B
Common Stock (or, at the election of the holder of Class B Shares, into 0.739 of
one share of General Signal Common Stock) and each Class C Share would be
converted into the right to
 
                                       22
<PAGE>   26
 
receive 2.001 shares of General Signal Class B Common Stock (or at the election
of the holder of Class C Shares, into 2.001 shares of General Signal Common
Stock). The General Signal Merger Agreement also provides that for each share of
General Signal Common Stock or General Signal Class B Common Stock issued in the
Proposed General Signal Merger, one General Signal Common Stock purchase right
or one General Signal Class B Common Stock purchase right (as applicable) would
be issued pursuant to the General Signal Rights Agreement. According to the
Company 8-A, the Rights, if still outstanding, will expire immediately prior to
the effective time of the Proposed General Signal Merger.
 
     The General Signal Merger Agreement provides that, among other things, the
Company and its subsidiaries, and their directors, officers, employees, agents
and representatives, will not solicit or encourage (including by way of
furnishing non-public information) any inquiry or proposal with respect to a
Company Acquisition Transaction or communicate with any third party with respect
to any Company Acquisition Transaction or enter into any agreement requiring the
Company to abandon the Proposed General Signal Merger; provided that, in
response to an unsolicited written proposal with respect to a Company
Acquisition Transaction from a financially capable third party that contains no
financing condition, the Company may furnish non-public information and
negotiate or otherwise communicate with such third party if the Company's Board
of Directors determines that taking such action is reasonably likely to lead to
a Company Acquisition Transaction more favorable than the Proposed General
Signal Merger and determines (and the Company's outside counsel opines in
writing) that failing to take such action would constitute a breach of its
fiduciary duties.
 
     Rockwell believes that the Offer will permit the Company to furnish
Rockwell with non-public information pursuant to these provisions. The General
Signal Merger Agreement further provides that General Signal may terminate the
General Signal Merger Agreement in the event the Company's Board of Directors
(i) withdraws or adversely changes its recommendation with respect to the
Proposed General Signal Merger, (ii) recommends any proposal in respect of a
Company Acquisition Transaction, or (iii) furnishes non-public information to or
negotiates or communicates with a third party with respect to any Company
Acquisition Transaction or publicly discloses a resolution to do any of the
foregoing. Under Section 9.05(b) of the General Signal Merger Agreement, if
General Signal terminates the General Signal Merger Agreement under such
circumstances, the Company will be required to reimburse General Signal for up
to $2.5 million of documented fees and expenses and to pay General Signal an
additional fee of $50 million.
 
     On October 19, 1994, the Board of Directors of Rockwell approved the
commencement of the Offer, and on October 20, 1994, Rockwell sent a letter to
the Company and issued a press release stating that its directors had authorized
the acquisition of the Company at a price of $30 per Class A Share and an
equivalent price for convertible shares (i.e., the Class B Shares and the Class
C Shares, based on their respective conversion ratios of 1 to 1 and 2.708 to 1).
The following is the text of Rockwell's October 20 letter:
 
Mr. H. Virgil Sherrill
Chairman of the Board
and
Mr. John C. Morley
President and Chief Executive Officer
Reliance Electric Company
6065 Parkland Boulevard
Cleveland, Ohio 44124
 
Gentlemen:
 
     As you know, Rockwell and Reliance Electric over the years have worked
together closely and cordially on a number of projects and, during this time,
have discussed a business combination of our two companies. As recently as this
past July, Rockwell expressed its interest in acquiring Reliance Electric, and
we urged you, John, to communicate our interest to the Reliance Electric board,
which you indicated you would do. We were therefore surprised and disappointed
that Rockwell was not afforded an opportunity to further pursue those
discussions before Reliance Electric and General Signal Corporation announced a
definitive merger agreement at the end of August.
 
                                       23
<PAGE>   27
 
     After an intensive strategic review, including a detailed evaluation of
publicly available information concerning Reliance Electric, we have concluded
that the strategic and financial advantages of combining our two companies are
too compelling to ignore.
 
     Accordingly, I am writing to inform you of our intention to acquire
Reliance Electric through a cash tender offer of $30 per share for all shares of
Reliance Electric's Class A common stock and an equivalent price for its
convertible shares. This represents an exceptionally attractive opportunity for
your shareowners -- specifically, an all-cash offer at a premium of 22.4% over
yesterday's closing market price of $24.50 per Class A share and 50.9% over the
closing market price on August 29, the day before Reliance Electric's merger
agreement with General Signal was announced.
 
     The transaction we propose also represents a particularly attractive
opportunity to build a combined enterprise uniquely positioned for continued
leadership in both the control and power segments of the industrial automation
business, in North America and around the world.
 
     Combining the operations of our Allen-Bradley automation business and
Reliance Electric will establish a global industrial automation enterprise with
combined annual sales of about $3.5 billion. It will have a broad range of
man-machine interface, sensor, control logic, mechanical transmission, motor and
motor controller products, drive systems capabilities, and global support
services. As such, the combined business can better capitalize on an important,
long-term technological trend in industrial automation: the convergence of the
control and power functions in increasingly intelligent automation products.
 
     We have enormous respect for Reliance Electric, a major manufacturer of
industrial products and telecommunications equipment. As you know,
Allen-Bradley, which we acquired in 1985 as part of our continuing strategic
program to grow the commercial side of our company, has established Rockwell as
a leading worldwide manufacturer of automation control products. Since the
acquisition, Allen-Bradley has more than doubled its sales, and expects to
report sales of more than $2.1 billion for fiscal 1994.
 
     Allen-Bradley has many strengths in control logic, man-machine interfaces
and sensors. Reliance Electric has complementary strengths in motors and drives.
Supported by Rockwell's financial resources and advanced technology, the
combined entity will be a formidable U.S. - based global industrial automation
enterprise, well-positioned to compete with its international competitors.
 
     Our offer is not subject to any financing contingencies. In addition, we
are advised by our legal counsel that there are no significant antitrust or
other issues associated with a combination of our two companies.
 
     While Rockwell is and will continue to be actively engaged in various
telecommunications markets, we have determined to sell Reliance Electric's
telecommunications operations because they do not fit into Rockwell's strategic
plans.
 
     We are convinced that a combination of Allen-Bradley and Reliance Electric
makes compelling strategic and financial sense for both our companies and our
respective constituents. I stand ready to meet with your board to present our
plans.
 
Sincerely,
 
/s/  Donald R. Beall

11. PURPOSE OF THE OFFER AND THE PROPOSED ROCKWELL MERGER; PLANS FOR THE
COMPANY.
 
PURPOSE OF THE OFFER AND THE PROPOSED ROCKWELL MERGER
 
     The purpose of the Offer and the Proposed Rockwell Merger is to acquire
control of, and the entire equity interest in, the Company. The Purchaser
currently intends, as soon as practicable following completion of the Offer, to
seek the maximum representation obtainable on the Company's Board of Directors
and to consummate the Proposed Rockwell Merger. The purpose of the Proposed
Rockwell Merger is to acquire all Shares not tendered and purchased pursuant to
the Offer or otherwise. Pursuant to the Proposed Rockwell Merger, each then
outstanding Share (other than Shares owned by Rockwell or any of its
wholly-owned subsidiaries, Shares held in the treasury of the Company, and
Shares held by stockholders who perfect appraisal rights under the Delaware Law)
would be converted into the right to receive cash in the same amount as received
per the applicable Share in the Offer, and the Company would become a
wholly-owned subsidiary of Rockwell.
 
     The Purchaser reserves the right to amend the Offer (including amending the
purchase price) upon entry into a merger agreement with the Company or otherwise
or to negotiate a merger agreement with the Company not involving a tender
offer. See Section 14. In the event that Rockwell is unable to negotiate a
definitive merger agreement with the Company, Rockwell will make a determination
whether to seek through a proxy contest sufficient representation on the
Company's Board of Directors to cause the Board of Directors to approve the
Proposed Rockwell Merger and satisfy the Rights Condition and the Section 203
Condition and thereby permit the Offer and the Proposed Rockwell Merger to be
consummated. In connection therewith, Rockwell may solicit calls for a special
meeting of stockholders of the Company pursuant to Section 1.2 of the Company's
By-Laws, which permits the holders of a majority of the Company's voting stock
(as well as the Chairman of the Board, the President, or the Board of Directors
of the Company) to call such a special meeting.
 
     The Purchaser reserves the right to acquire additional Shares after
consummation of the Offer in open market purchases, through a tender offer, in
privately negotiated transactions or otherwise in order to obtain a sufficient
number of Shares to approve the transactions contemplated hereby. In addition,
after consummation of the Offer, whether or not the Purchaser acquires
additional Shares, the Purchaser currently intends to seek to enter into the
Proposed Rockwell Merger with the Company.
 
     Consummation of the Proposed Rockwell Merger would require the adoption of
a resolution by the Company's Board of Directors approving the Proposed Rockwell
Merger and a related agreement and the affirmative vote of the holders of a
majority of the Class A Shares (according to the Company Certificate of
Incorporation, the Class B Shares and Class C Shares are not entitled to voting
rights). Assuming that the Offer is consummated and that the Minimum Condition
and the other conditions to the Offer are satisfied, the Purchaser will hold a
majority of the Class A Equivalent Shares outstanding and, upon conversion of
Class B Shares and Class C Shares held by the Purchaser into Class A Shares, the
Purchaser will hold sufficient Class A Shares to approve the Proposed Rockwell
Merger.
 
     The making of the Offer will enable the Purchaser to commence the process
of seeking regulatory approvals for its acquisition of the Company. See Section
15. In addition, by tendering Shares into the Offer, the Company's stockholders
effectively will be given the opportunity to express to the Company's Board of
Directors that they wish to be able to accept the Offer and to approve the
Proposed Rockwell Merger or a similar transaction with Rockwell.
 
     THE OFFER DOES NOT CONSTITUTE A SOLICITATION OF PROXIES FOR ANY MEETING OR
A SOLICITATION OF CALLS FOR A SPECIAL MEETING OF THE COMPANY'S STOCKHOLDERS. ANY
SUCH SOLICITATION WHICH ROCKWELL OR THE PURCHASER MIGHT MAKE WOULD BE MADE ONLY
PURSUANT TO SEPARATE PROXY OR SOLICITATION MATERIALS COMPLYING WITH ALL
APPLICABLE REQUIREMENTS OF SECTION 14(A) OF THE EXCHANGE ACT, AND THE RULES AND
REGULATIONS PROMULGATED THEREUNDER.

PLANS FOR THE COMPANY
 
     If Rockwell acquires control of the Company, it intends to conduct a
further review of the Company and its subsidiaries and their respective assets,
businesses, corporate structure, capitalization, operations, properties,
policies, management and personnel. After such review, Rockwell will determine
what actions or changes, if any, would be desirable in light of the
circumstances which then exist, and reserves the right to effect such actions or
changes. Rockwell's decisions could be affected by information hereafter
obtained, changes in general economic or market conditions or in the business of
the Company or its subsidiaries, actions by the Company or its subsidiaries and
other factors. However, Rockwell has determined to sell, following completion of
the Offer and the Proposed Rockwell Merger, Reliance Comm/Tec Corporation, a
wholly-owned subsidiary of the Company.
 
     Except as described in this Offer to Purchase, neither Rockwell nor the
Purchaser has any present plans or proposals that would relate to or would
result in (i) an extraordinary corporate transaction, such as a merger,
reorganization or liquidation, involving the Company or any of its subsidiaries,
(ii) a sale or transfer of a material amount of assets of the Company or any of
its subsidiaries, (iii) any change in the present Board of Directors or
management of the Company, (iv) any material changes in the present
capitalization or dividend policy of the Company, (v) any other material change
in the Company's corporate structure or business, (vi) causing a class of
securities of the Company to be delisted from a national securities exchange or
to cease to be authorized to be quoted in an inter-dealer quotation system of a
registered national securities association or (vii) a class of equity securities
of the Company becoming eligible for termination of registration pursuant to
Section 12(g)(4) of the Exchange Act.
 
     If the Offer is consummated, the Purchaser will hold a majority of the
Class A Equivalent Shares outstanding and, upon conversion of Class B Shares and
Class C Shares held by the Purchaser into Class A Shares, the Purchaser will
hold sufficient Class A Shares to approve the Proposed Rockwell Merger. However,
in light of the restrictions described below, there can be no assurance that the
Proposed Rockwell Merger will be proposed to stockholders of the Company or be
consummated or as to the timing thereof. Nonetheless, if the Board of Directors
of the Company votes to redeem the Rights and approve the Offer and the Proposed
Rockwell Merger, the Rights Condition and the Section 203 Condition will be
satisfied.
 
     Neither Rockwell nor the Purchaser can give any assurance as to whether, as
a result of information hereafter obtained by either Rockwell or the Purchaser,
changes in general economic or market conditions or in the business of the
Company, or other presently unforeseen factors, the Proposed Rockwell Merger
will be proposed to the Company's stockholders or whether the Proposed Rockwell
Merger will be delayed or abandoned. If for any reason the Proposed Rockwell
Merger is not consummated, Rockwell and the Purchaser reserve the right to
acquire additional Shares following the expiration of the Offer through private
purchases, market transactions, tender or exchange offers or otherwise on terms
and at prices that may be more or less favorable than those of the Offer or,
subject to any applicable legal restrictions, to dispose of any or all Shares
acquired by Rockwell and the Purchaser.
 
STATUTORY REQUIREMENTS
 
     In general, under the Delaware Law, a merger of two Delaware corporations
requires the adoption of a resolution by the Board of Directors of each of the
corporations desiring to merge approving an agreement of merger containing
provisions with respect to certain statutorily specified matters and the
approval of such agreement of merger by the stockholders of each corporation by
the affirmative vote of the holders of a majority of all the outstanding shares
of stock entitled to vote on such merger. According to the Company Certificate
of Incorporation, only Class A Shares of the Company entitle the holders thereof
to voting rights.
 
     Assuming that the Offer is consummated and that the Minimum Condition and
the other conditions to the Offer are satisfied, the Purchaser will hold a
majority of the Class A Equivalent Shares outstanding and, upon conversion of
Class B Shares and Class C Shares held by the Purchaser into Class A Shares, the
Purchaser will hold sufficient Class A Shares to approve the Proposed Rockwell
Merger. However, the Delaware Law also provides that if a parent company owns at
least 90% of each class of stock of a subsidiary, the parent company can effect
a short-form merger with that subsidiary without the action of the other
 
                                       26
<PAGE>   30
 
stockholders of the subsidiary. Accordingly, if, as a result of the Offer or
otherwise, the Purchaser acquires or controls the voting power of at least 90%
of each class of the Shares, the Purchaser could, and intends to, effect the
Proposed Rockwell Merger without prior notice to, or any action by, any other
stockholder of the Company.
 
     Delaware Business Combination Law.  In general, Section 203 of the Delaware
Law provides that a Delaware corporation such as the Company may not engage in
any Business Combination (defined to include a variety of transactions,
including a merger) with any Interested Stockholder (defined generally as a
person that, directly or indirectly, beneficially owns 15% or more of the
corporation's outstanding voting stock), or any affiliate of an Interested
Stockholder, for three years after the date on which the Interested Stockholder
becomes an Interested Stockholder. The three-year prohibition on Business
Combinations with Interested Stockholders (the "Business Combination
Prohibition") does not apply if certain conditions, described below, are
satisfied. Section 203 of the Delaware Law provides that a "beneficial owner" of
voting stock includes any person who, individually or together with any of its
affiliates or associates, has (i) the right to acquire voting stock (whether
such right is exercisable immediately or only after the passage of time)
pursuant to any agreement, arrangement or understanding or upon the exercise of
conversion rights, exchange rights, warrants or options or otherwise, (ii) the
right to vote such stock pursuant to any agreement, arrangement or
understanding, or (iii) any agreement, arrangement or understanding for the
purposes of acquiring, holding, voting or disposing of such stock with any other
person that beneficially owns, directly or indirectly, such stock.
 
     The Business Combination Prohibition does not apply to a particular
Business Combination between a corporation and a particular Interested
Stockholder if (i) prior to the date such Interested Stockholder became an
Interested Stockholder, the board of directors of such corporation approved
either the Business Combination or the transaction which resulted in the
stockholder becoming an Interested Stockholder, or (ii) upon consummation of the
transaction which resulted in the stockholder becoming an Interested
Stockholder, the Interested Stockholder owned at least 85% of the voting stock
of the corporation outstanding at the time the transaction commenced, excluding
for purposes of determining the number of shares outstanding those shares held
by (x) persons who are directors and also officers of the corporation and (y)
employee stock plans in which employee participants do not have the right to
determine confidentially whether shares held subject to the plan will be
tendered in a tender or exchange offer, or (iii) on or subsequent to the date
the stockholder becomes an Interested Stockholder, the Business Combination is
(a) approved by the board of directors of the corporation and (b) authorized at
an annual or special meeting of stockholders by the affirmative vote of at least
66 2/3% of the outstanding voting stock of the corporation which is not owned by
the Interested Stockholder.
 
     Section 203(b)(6) of the Delaware Law provides that the restrictions
contained in Section 203 of the Delaware Law do not apply to a Business
Combination that is proposed prior to the consummation or abandonment of and
following the announcement or notification of one of certain extraordinary
transactions (including a merger) involving the corporation which transaction
(i) is with or by a person who either was not an Interested Stockholder during
the previous three years or who became an Interested Stockholder with the
approval of the corporation's board of directors and (ii) has been approved or
has not been opposed by a majority of the members of the board of directors then
in office who were directors prior to any person becoming an Interested
Stockholder during the previous three years or were recommended for election or
elected to succeed such directors by a majority of such directors. Accordingly,
the Purchaser believes that, because the General Signal Merger Agreement was
approved by the Board of Directors of the Company, the restrictions on Business
Combinations contained in Section 203 are inapplicable to the Proposed Rockwell
Merger pursuant to Section 203(b)(6).
 
     The foregoing summary of Section 203 of the Delaware Law does not purport
to be complete and is qualified in its entirety by reference to the provisions
of Section 203 of the Delaware Law.
 
APPRAISAL RIGHTS
 
     No appraisal rights are available in connection with the Offer. However, if
the Proposed Rockwell Merger is consummated, stockholders of the Company will
have certain rights under Section 262 of the Delaware Law
 
                                       27
<PAGE>   31
 
to dissent and demand appraisal of, and payment in cash of the fair value of,
their Shares. Such rights, if the statutory procedures were complied with, could
lead to a judicial determination of the fair value (excluding any element of
value arising from the accomplishment or expectation of the Proposed Rockwell
Merger) required to be paid in cash to such dissenting holders for their Shares.
Any such judicial determination of the fair value of Shares could be based upon
considerations other than, or in addition to, the price paid in the Offer and
the market value of the Shares, including asset values and the investment value
of the Shares. The value so determined could be more or less than the purchase
price per the applicable Share pursuant to the Offer or the consideration per
the applicable Share to be paid in the Proposed Rockwell Merger.
 
     In addition, several decisions by Delaware courts have held that, in
certain instances, a controlling stockholder of a corporation involved in a
merger has a fiduciary duty to the other stockholders that requires the merger
to be fair to such other stockholders. In determining whether a merger is fair
to minority stockholders, the Delaware courts have considered, among other
things, the type and amount of consideration to be received by the stockholders
and whether there were fair dealings among the parties. Although the remedies of
rescission or other damages are possible in an action challenging a merger as a
breach of fiduciary duty, decisions of the Delaware courts have indicated that
in most cases the remedy available in a merger that is found not to be "fair" to
minority stockholders is a damages remedy based on essentially the same
principles as an appraisal.
 
     THE FOREGOING SUMMARY OF THE RIGHTS OF OBJECTING STOCKHOLDERS DOES NOT
PURPORT TO BE A COMPLETE STATEMENT OF THE PROCEDURES TO BE FOLLOWED BY
STOCKHOLDERS DESIRING TO EXERCISE ANY AVAILABLE DISSENTERS' RIGHTS. The
preservation and exercise of dissenters' rights require strict adherence to the
applicable provisions of the Delaware Law.
 
THE RIGHTS
 
     According to the Company 8-A, on August 29, 1994, the Board of Directors of
the Company declared a dividend distribution of one Right for each outstanding
Class A Share, Class B Share and Class C Share to purchase one one-hundredth of
a share of a new Series A, Series B or Series C Preferred Stock, respectively.
The distribution was paid on September 15, 1994 to stockholders of record on
that date. Each Right entitles the registered holder of Class A Shares or Class
B Shares to purchase from the Company one one-hundredth of a share of Series A
or Series B Preferred Stock, respectively, at an exercise price of $60.00,
subject to adjustment, and the registered holder of Class C Shares to purchase
from the Company one one-hundredth of a share of Series C Preferred Stock at an
exercise price of $162.48, subject to adjustment.
 
     According to the Company 8-A, until the close of business on the
Distribution Date (which will occur on the earlier of (i) the tenth day
following a public announcement that a person or group of affiliated or
associated persons (an "Acquiring Person") has acquired, or obtained the right
to acquire, beneficial ownership of 10% or more of the outstanding Class A
Shares or (ii) the tenth business day (or such later date as may be determined
by action of the Company's Board of Directors prior to the time any person or
group becomes an Acquiring Person) after the commencement of, or announcement of
intention to make, a tender offer or exchange offer which would result in the
beneficial ownership by a person or group of 10% or more of the outstanding
Class A Shares), the Rights will be evidenced by and transferred with, and only
with, the associated Shares. Until the Distribution Date (or earlier redemption
or expiration of the Rights), new Share Certificates will contain a legend
incorporating the Rights Agreement by reference, and the surrender for transfer
of any Share Certificate representing Shares outstanding on September 15, 1994
will also constitute the transfer of the Rights associated with the Shares
represented by such Share Certificate. As soon as practicable following the
Distribution Date, separate Rights Certificates will be mailed to holders of
record of the Shares as of the close of business on the Distribution Date, and
thereafter the separate Rights Certificates alone will evidence the Rights.
 
     According to the Company 8-A, the Rights are not exercisable until the
Distribution Date. The Rights will expire at the earliest of (i) the close of
business on August 29, 2004, (ii) the time at which the Rights are
 
                                       28
<PAGE>   32
 
redeemed by the Company as described below, (iii) immediately prior to the
effective time of the Proposed General Signal Merger or (iv) the time at which
such Rights are exchanged.
 
     According to the Company 8-A, in the event that the Company is acquired in
a merger or other business combination transaction or 50% or more of its
consolidated assets or earning power are sold, proper provision will be made so
that each holder of a Right will thereafter have the right to receive, upon the
exercise thereof at the then current exercise price of the Right, that number of
shares of common stock of the acquiring company which at the time of such
transaction will have a market value of two times the exercise price of the
Right.
 
     According to the Company 8-A, in the event that any person or group becomes
an Acquiring Person, proper provision shall be made so that each holder of a
Right, other than Rights beneficially owned by the Acquiring Person (which will
thereafter be void), will thereafter have the right to receive upon exercise
that number of Shares (of the same class as the series of preferred stock
associated with such Right) having a market value of two times the exercise
price of the Right.
 
     According to the Company 8-A, at any time until the time a person or group
becomes an Acquiring Person, the Board of Directors of the Company may redeem
the Rights in whole, but not in part, at a price of $.01 per Right, subject to
adjustment (the "Redemption Price"). Immediately upon the action of the Board of
Directors of the Company ordering redemption of the Rights, the right to
exercise the Rights will terminate, and the holders of Rights will only be
entitled to receive the Redemption Price.
 
     According to the Company 8-A, until a Right is exercised, the holder
thereof, as such, will have no rights as a stockholder of the Company,
including, without limitation, the right to vote or to receive dividends.
 
     According to the Company 8-A, the terms of the Rights may be amended by the
Board of Directors of the Company without the consent of the holders of the
Rights, except that from and after such time as any person becomes an Acquiring
Person no such amendment may adversely affect the interests of the holders of
the Rights.
 
     The foregoing summary of the Rights Agreement does not purport to be
complete and is qualified in its entirety by reference to the Company 8-A and
the text of the Rights Agreement as set forth as an exhibit thereto, filed with
the Commission, copies of which may be obtained in the manner set forth in
Section 8.
 
     If the Rights Condition is not satisfied and the Purchaser elects, in its
sole discretion, to waive the Rights Condition and consummate the Offer, and if
there are outstanding Rights which have not been acquired by the Purchaser, the
Purchaser will evaluate its alternatives. Such alternatives could include
purchasing additional Rights in the open market, in privately negotiated
transactions, in another tender or exchange offer or otherwise. Any such
additional purchase of Rights could be for cash or other consideration. Under
such circumstances, the Proposed Rockwell Merger might be delayed or abandoned
as impracticable. The form and amount of consideration to be received by the
holders of Shares in the Proposed Rockwell Merger, if consummated, might be
subject to adjustment to compensate the Purchaser for, among other things, the
costs of acquiring Rights and a portion of the potential dilution cost to the
Purchaser of Rights not owned by the Purchaser and its wholly owned subsidiaries
at the time of the Proposed Rockwell Merger. In such event, the consideration
paid for Shares in the Proposed Rockwell Merger could be substantially less than
the consideration paid in the Offer. In addition, the Purchaser may elect under
such circumstances not to consummate the Proposed Rockwell Merger.
 
     UNLESS AND UNTIL THE PURCHASER DECLARES THAT THE RIGHTS CONDITION IS
SATISFIED, STOCKHOLDERS WILL BE REQUIRED TO TENDER ONE ASSOCIATED RIGHT FOR EACH
SHARE TENDERED IN ORDER TO EFFECT A VALID TENDER OF SUCH SHARE. IF THE
DISTRIBUTION DATE DOES NOT OCCUR PRIOR TO THE EXPIRATION DATE, A TENDER OF
SHARES WILL ALSO CONSTITUTE A TENDER OF THE ASSOCIATED RIGHTS. SEE SECTIONS 1
AND 3.
 
                                       29

"GOING PRIVATE" TRANSACTIONS
 
     The Commission has adopted Rule 13e-3 under the Exchange Act which is
applicable to certain "going private" transactions and which may under certain
circumstances be applicable to the Proposed Rockwell Merger. However, Rule 13e-3
would be inapplicable if (i) the Class A Shares are deregistered under the
Exchange Act prior to the Proposed Rockwell Merger or other business combination
or (ii) the Proposed Rockwell Merger or other business combination is
consummated within one year after the purchase of the Shares pursuant to the
Offer and the amount paid per Share for each class of Share in the Proposed
Rockwell Merger or other business combination is at least equal to the amount
paid per Share for such class of Share in the Offer. If applicable, Rule 13e-3
requires, among other things, that certain financial information concerning the
fairness of the proposed transaction and the consideration offered to minority
stockholders in such transaction be filed with the Commission and disclosed to
stockholders prior to the consummation of the transaction.
 
12. SOURCE AND AMOUNT OF FUNDS.  The total amount of funds required by the
Purchaser to purchase all outstanding Shares pursuant to the Offer and to pay
fees and expenses related to the Offer and the Proposed Rockwell Merger is
estimated to be approximately $1.6 billion. The Purchaser plans to obtain all
funds needed for the Offer and the Proposed Rockwell Merger through a capital
contribution which will be made by Rockwell to the Purchaser. Rockwell plans to
use funds it has available in its cash accounts and by borrowing under a
revolving credit agreement to be negotiated by Rockwell with a group of banks
for such capital contribution. Although there are no commitments by such banks
at this time, Rockwell believes such credit agreement will be in effect prior to
the initial Expiration Date. Rockwell expects that such borrowings would be
repaid from the net proceeds of the sale of the Company's wholly-owned
subsidiary, Reliance Comm/Tec Corporation, and from cash flow from the normal
operations of Rockwell's businesses. The Offer is not conditioned on obtaining
financing.
 
13. DIVIDENDS AND DISTRIBUTIONS.  If, on or after August 30, 1994, the Company
(i) splits, combines or otherwise changes the Shares or its capitalization, (ii)
acquires Shares or otherwise causes a reduction in the number of Shares, (iii)
issues or sells additional Shares (other than the issuance of Shares reserved
for issuance as of August 30, 1994 under option and employee stock purchase
plans in accordance with their terms as publicly disclosed as of August 30,
1994) or any shares of any other class of capital stock, other voting securities
or any securities convertible into or exchangeable for, or rights (other than
the Rights), warrants or options, conditional or otherwise, to acquire, any of
the foregoing or (iv) discloses that it has taken such action, then, without
prejudice to the Purchaser's rights under Section 14, the Purchaser, in its sole
discretion, may make such adjustments in the purchase price and other terms of
the Offer and the Proposed Rockwell Merger as it deems appropriate to reflect
such split, combination or other change or action, including, without
limitation, the Minimum Condition or the number or type of securities offered to
be purchased.
 
     If on or after August 30, 1994, the Company declares or pays any dividend
on the Shares or any distribution (including, without limitation, the issuance
of additional Shares pursuant to a stock dividend or stock split, the issuance
of other securities or the issuance of rights (other than the separation of the
Rights from the Shares) for the purchase of any securities) with respect to the
Shares or Rights (other than the Redemption Price) that is payable or
distributable to stockholders of record on a date prior to the transfer into the
name of the Purchaser or its nominees or transferees on the Company's stock
transfer records of the Shares and Rights purchased pursuant to the Offer
(except that if the Rights are redeemed by the Company's Board of Directors,
tendering stockholders who are holders of record as of the applicable record
date will be entitled to receive and retain the Redemption Price), and if Shares
are purchased in the Offer, then, without prejudice to the Purchaser's rights
under Section 14, (i) the purchase price per Share payable by the Purchaser
pursuant to the Offer shall be reduced by the amount of any such cash dividend
or cash distribution and (ii) any such non-cash dividend, distribution,
issuance, proceeds or rights to be received by the tendering stockholders shall
(a) be received and held by the tendering stockholders for the account of the
Purchaser and will be required to be promptly remitted and transferred by each
tendering stockholder to the Depositary for the account of the Purchaser,
accompanied by appropriate documentation of transfer or (b) at the direction of
the Purchaser, be exercised for the benefit of the Purchaser, in which case the
proceeds of such exercise will
 
                                       30
<PAGE>   34
 
promptly be remitted to the Purchaser. Pending such remittance and subject to
applicable law, the Purchaser will be entitled to all rights and privileges as
owner of any such non-cash dividend, distribution, issuance, proceeds or rights
and may withhold the entire purchase price or deduct from the purchase price the
amount or value thereof, as determined by the Purchaser in its sole discretion.
 
14. CERTAIN CONDITIONS OF THE OFFER.  Notwithstanding any other provision of the
Offer, the Purchaser shall not be required to accept for payment or, subject to
any applicable rules and regulations of the Commission, including Rule 14e-1(c)
under the Exchange Act (relating to the Purchaser's obligation to pay for or
return tendered Shares promptly after expiration or termination of the Offer),
to pay for any Shares tendered, and may postpone the acceptance for payment or,
subject to the restriction referred to above, payment for any Shares tendered,
and may amend or terminate the Offer (whether or not any Shares have theretofore
been purchased or paid for) if, in the sole judgment of the Purchaser, (i) any
condition to consummation of the Offer set forth in the Introduction to this
Offer to Purchase (relating to the Minimum Condition, the No Impediments
Condition, the Rights Condition or the Section 203 Condition) has not been
satisfied or (ii) at any time on or after October 19, 1994 and before acceptance
for payment of, or payment for, such Shares any of the following events shall
occur or shall be deemed by the Purchaser to have occurred or Rockwell or the
Purchaser shall have learned about any such events applicable to or affecting
the Company or any of its affiliates which shall not have been previously
publicly disclosed by the Company:
 
          (a) there shall have been threatened, instituted or pending any
     action, proceeding, application, claim or counterclaim by or before any
     court, government or governmental, regulatory or administrative agency,
     authority or tribunal, domestic, foreign or supranational (whether brought
     by the Company, an affiliate of the Company or any other person or entity),
     which (i) challenges or seeks to challenge the acquisition by the Purchaser
     of the Shares or Rights (or any of them), restrains, prohibits or delays or
     seeks to restrain, prohibit or delay the making or consummation of the
     Offer or the Proposed Rockwell Merger or any other merger or business
     combination involving the Purchaser or any of its affiliates and the
     Company or any of its subsidiaries, restrains or prohibits or seeks to
     restrain or prohibit the performance of any of the contracts or other
     agreements or arrangements entered into by the Purchaser or any of its
     affiliates in connection with the acquisition of the Company or the Shares
     or Rights (or any of them), or seeks to obtain any damages in connection
     with any of the foregoing, (ii) makes or seeks to make the purchase of or
     payment for, some or all of the Shares or Rights pursuant to the Offer, the
     Proposed Rockwell Merger or otherwise, illegal, or results in or may result
     in a delay in the ability of the Purchaser to accept for payment or pay for
     some or all of the Shares or Rights or to consummate the Proposed Rockwell
     Merger, (iii) imposes or seeks to impose limitations on the ability of
     Rockwell, the Purchaser or the Company or any of their respective
     affiliates or subsidiaries effectively to acquire or hold, or requiring
     Rockwell, the Purchaser, the Company or any of their respective affiliates
     or subsidiaries to dispose of or hold separate, any portion of the assets
     or the business of Rockwell, the Purchaser, the Company or any of their
     respective affiliates or subsidiaries or imposes or seeks to impose
     limitations on the ability of Rockwell, the Purchaser, the Company or any
     of their respective affiliates or subsidiaries to continue to conduct, own
     or operate all or any portion of their businesses and assets as heretofore
     conducted, owned or operated, (iv) imposes or seeks to impose or results in
     or may result in material limitations on the ability of Rockwell, the
     Purchaser or any of their affiliates to exercise full rights of ownership
     of the Shares or Rights purchased by them, including, but not limited to,
     the right to vote the Shares purchased by them on all matters properly

     accelerated or otherwise become due or become subject to acceleration prior
     to its stated due date, in any case with or without notice or the lapse of

     Company or any of its subsidiaries (including, but not limited to, any
     event of default that may result from the consummation of the Offer, the
     acquisition of control of the Company or any of its subsidiaries or the

     Company) or (y) the value of the Shares in the hands of Rockwell, the

     in order to make the statements made therein, in light of the circumstances
     under which they were made, not misleading; or
 
          (j) except as may be required by law, the Company or any of its
     subsidiaries shall have taken any action to terminate or amend any employee
     benefit plan (as defined in Section 3(2) of the Employee Retirement Income
     Security Act of 1974, as amended) of the Company or any of its
     subsidiaries; or
 
          (k) any waiting periods under the HSR Act applicable to the purchase
     of the Shares pursuant to the Offer shall not have expired or been
     terminated, there shall not have been a determination or a deemed
     determination pursuant to the EC Merger Regulation that the purchase of the
     Shares pursuant to the Offer is compatible with the common market, any
     waiting periods under the Competition Act applicable to the purchase of the
     Shares pursuant to the Offer shall not have expired or been terminated, or
     any other approval, permit, authorization, consent or other action of any
     domestic, foreign or supranational governmental, administrative or
     regulatory agency, authority or tribunal (including those described in
     Section 15) shall not have been obtained on terms satisfactory to the
     Purchaser in its sole discretion.
 
     The foregoing conditions are for the sole benefit of the Purchaser and its
affiliates and may be asserted by the Purchaser regardless of the circumstances
(including, without limitation, any action or inaction by the Purchaser or any
of its affiliates) giving rise to any such condition or may be waived by the
Purchaser, in whole or in part, from time to time in its sole discretion. The
failure by the Purchaser at any time to exercise any of the foregoing rights
shall not be deemed a waiver of any such rights and each such right shall be
deemed an ongoing right and may be asserted at any time and from time to time.
Any determination by the Purchaser concerning any of the events described in
this Section 14 shall be final and binding.
 
     A public announcement may be made of a material change in, or waiver of,
such conditions and the Offer may, in certain circumstances, be extended in
connection with any such change or waiver.
 
     The Purchaser acknowledges that the Commission believes that (a) if the
Purchaser is delayed in accepting the Shares it must either extend the Offer or
terminate the Offer and promptly return the Shares
 
                                       34

and (b) the circumstances in which a delay in payment is permitted are limited
and do not include unsatisfied conditions of the Offer, except with respect to
any approval required under the HSR Act and most other regulatory approvals.
 
15. CERTAIN LEGAL MATTERS; REQUIRED REGULATORY APPROVALS.  Except as set forth
in this Offer to Purchase, based on its review of publicly available filings by
the Company with the Commission and other publicly available information
regarding the Company, neither Rockwell nor the Purchaser is aware of any
licenses or regulatory permits that appear to be material to the business of the
Company and its subsidiaries, taken as a whole, and that might be adversely
affected by the Purchaser's acquisition of Shares (and the indirect acquisition
of the stock of the Company's subsidiaries) as contemplated herein, or any
filings, approvals or other actions by or with any domestic, foreign or
supranational governmental authority or administrative or regulatory agency that
would be required for the acquisition or ownership of the Shares (or the
indirect acquisition of the stock of the Company's subsidiaries) by the
Purchaser pursuant to the Offer as contemplated herein. Should any such approval
or other action be required, it is presently contemplated that such approval or
action would be sought except as described below under "State Takeover Laws."
Should any such approval or other action be required, there can be no assurance
that any such approval or action, if needed, would be obtained without
substantial conditions or that adverse consequences might not result to the
Company's or its subsidiaries' businesses, or that certain parts of the
Company's, Rockwell's, the Purchaser's or any of their respective subsidiaries'
businesses might not have to be disposed of or held separate or other
substantial conditions complied with in order to obtain such approval or action
or in the event that such approvals were not obtained or such actions were not
taken. The Purchaser's obligation to purchase and pay for Shares is subject to
certain conditions, including conditions with respect to litigation and
governmental actions. See the Introduction and Section 14 for a description
thereof.
 
     State Takeover Laws.  A number of states (including Delaware, where the
Company is incorporated) have adopted takeover laws and regulations which
purport, to varying degrees, to be applicable to attempts to acquire securities
of corporations which are incorporated in such states or which have substantial
assets, stockholders, principal executive offices or principal places of
business therein. To the extent that certain provisions of certain of these
state takeover statutes purport to apply to the Offer or the Proposed Rockwell
Merger, the Purchaser believes that such laws conflict with federal law and
constitute an unconstitutional burden on interstate commerce. In 1982, the
Supreme Court of the United States, in Edgar v. Mite Corp., invalidated on
constitutional grounds the Illinois Business Takeovers Statute, which as a
matter of state securities law, made takeovers of corporations meeting certain
requirements more difficult, and the reasoning in such decision is likely to
apply to certain other state takeover statutes. In 1987, however, in CTS Corp.
v. Dynamics Corp. of America, the Supreme Court of the United States held that
the State of Indiana could, as a matter of corporate law and, in particular,
those aspects of corporate law concerning corporate governance, constitutionally
disqualify a potential acquiror from voting on the affairs of a target
corporation without the prior approval of the remaining stockholders, provided
that such laws were applicable only under certain conditions. Subsequently, in
TLX Acquisition Corp. v. Telex Corp., a Federal district court in Oklahoma ruled
that the Oklahoma statutes were unconstitutional insofar as they apply to
corporations incorporated outside Oklahoma in that they would subject such
corporations to inconsistent regulations. Similarly, in Tyson Foods, Inc. v.
McReynolds, a Federal district court in Tennessee ruled that four Tennessee
takeover statutes were unconstitutional as applied to corporations incorporated
outside Tennessee. This decision was affirmed by the United States Court of
Appeals for the Sixth Circuit. In December 1988, a Federal district court in
Florida held in Grand Metropolitan PLC v. Butterworth that the provisions of the
Florida Affiliated Transactions Act and Florida Control Share Acquisition Act
were unconstitutional as applied to corporations incorporated outside of
Florida.
 
     The Purchaser has not attempted to comply with any state takeover statutes
in connection with the Offer or the Proposed Rockwell Merger. The Purchaser
reserves the right to challenge the validity or applicability of any state law
allegedly applicable to the Offer or the Proposed Rockwell Merger and nothing in
this Offer to Purchase nor any action taken in connection herewith is intended
as a waiver of that right. In the event that it is asserted that one or more
takeover statutes apply to the Offer or the Proposed Rockwell Merger, and it is
not determined by an appropriate court that such statute or statutes do not
apply or are invalid as applied to the
 
                                       35
<PAGE>   39
 
Offer or the Proposed Rockwell Merger, as applicable, the Purchaser may be
required to file certain documents with, or receive approvals from, the relevant
state authorities, and the Purchaser might be unable to accept for payment or
purchase Shares tendered pursuant to the Offer or be delayed in continuing or
consummating the Offer. In such case, the Purchaser may not be obligated to
accept for purchase, or pay for, any Shares tendered. See Section 14.
 
     Antitrust.  Under the HSR Act, and the rules and regulations that have been
promulgated thereunder by the Federal Trade Commission (the "FTC"), certain
acquisition transactions may not be consummated until certain information and
documentary material has been furnished for review by the Antitrust Division of
the Department of Justice (the "Antitrust Division") and the FTC and certain
waiting period requirements have been satisfied. The acquisition of Shares
pursuant to the Offer and the Proposed Rockwell Merger is subject to such
requirements.
 
     Under the provisions of the HSR Act applicable to the Offer and the
Proposed Rockwell Merger, the purchase of Shares pursuant to the Offer and the
Proposed Rockwell Merger may not be consummated until the expiration of a
15-calendar-day waiting period following the filing of certain required
information and documentary material with respect to the Offer with the FTC and
the Antitrust Division, unless such waiting period is earlier terminated by the
FTC and the Antitrust Division. The Purchaser expects to file a Premerger
Notification and Report Form with the Antitrust Division and the FTC in
connection with the purchase of Shares pursuant to the Offer and the Proposed
Rockwell Merger under the HSR Act on October 21, 1994, and, in such event, the
required waiting period with respect to the Offer and the Proposed Rockwell
Merger will expire at 11:59 p.m., New York City time, on November 5, 1994,
unless earlier terminated by the Antitrust Division or the FTC or the Purchaser
receives a request for additional information or documentary material prior
thereto. If, within such 15-calendar-day waiting period, either the FTC or the
Antitrust Division were to request additional information or documentary
material from the Purchaser, the waiting period with respect to the Offer and
the Proposed Rockwell Merger would be extended for an additional period of 10
calendar days following the date of substantial compliance with such request by
the Purchaser. Only one extension of the waiting period pursuant to a request
for additional information is authorized by the rules promulgated under the HSR
Act. Thereafter, the waiting period could be extended only by court order or
with the consent of the Purchaser. The additional 10-calendar-day waiting period
may be terminated sooner by the FTC or the Antitrust Division. Although the
Company is required to file certain information and documentary material with
the Antitrust Division and the FTC in connection with the Offer, neither the
Company's failure to make such filings nor a request made to the Company from
the Antitrust Division or the FTC for additional information or documentary
material will extend the waiting period with respect to the purchase of Shares
pursuant to the Offer and the Proposed Rockwell Merger.
 
     The Antitrust Division and the FTC frequently scrutinize the legality under
the antitrust laws of transactions such as the acquisition of Shares by the
Purchaser pursuant to the Offer and the Proposed Rockwell Merger. At any time
before or after the Purchaser's purchase of Shares, the Antitrust Division or
the FTC could take such action under the antitrust laws as either deems
necessary or desirable in the public interest, including seeking to enjoin the
purchase of Shares pursuant to the Offer and the Proposed Rockwell Merger, the
divestiture of Shares purchased pursuant to the Offer or the divestiture of
substantial assets of Rockwell, the Purchaser, the Company or any of their
respective subsidiaries or affiliates. Private parties as well as state
attorneys general may also bring legal actions under the antitrust laws under
certain circumstances. See Section 14.
 
     Based upon an examination of publicly available information relating to the
businesses in which the Company is engaged, the Purchaser believes that the
acquisition of Shares pursuant to the Offer and the Proposed Rockwell Merger
should not violate the applicable antitrust laws. Nevertheless, there can be no
assurance that a challenge to the Offer and the Proposed Rockwell Merger on
antitrust grounds will not be made, or, if such challenge is made, what the
result will be. See Section 14.
 
     EC Merger Regulation.  According to publicly available information, the
Company may conduct substantial operations within the European Community (the
"EC") and certain of the individual member states of the EC. The EC Merger
Regulation requires that notices of concentrations with a "community
 
                                       36
<PAGE>   40
 
dimension" be provided to the EC Commission for review and approval prior to
being put into effect. The Offer will be deemed to have a "community dimension"
if the combined aggregate worldwide annual revenues of both the Company and
Rockwell exceeds ECU 5 billion, if the community-wide annual revenues of each of
the Company and Rockwell exceed ECU 250 million and if both the Company and
Rockwell do not receive more than two-thirds of their respective community-wide
revenues from one and the same member state. Based upon publicly available
information, the Purchaser believes that the Offer may be considered to have a
"community dimension." If the Offer falls within the EC Merger Regulation, the
EC Commission, as opposed to individual member states, has exclusive
jurisdiction to review it, subject to certain exceptions.
 
     Under the EC Merger Regulation, a concentration that meets the foregoing
guidelines requires the filing of a notice in a prescribed form with the EC
Commission. This filing must normally be made within seven days of the earlier
of the announcement of a public bid, the conclusion of the relevant agreement or
the acquisition of a controlling interest, although extensions of time are
sometimes granted. Transactions subject to the filing requirements of the EC
Merger Regulation are suspended automatically until three weeks after receipt of
the notice. The EC Commission may extend the suspension period for such period
as it finds necessary to make a final decision on the legality of the
transaction. In the case of a public bid, the bidder may acquire shares of the
target company during the suspension period, but may not vote such shares until
after the end of the period unless the EC Commission grants permission to do so
in order to maintain the full value of the bidder's investment.
 
     The EC Commission must decide whether to initiate proceedings within one
month after the receipt of the notice, subject to certain extensions for EC
holidays or if an individual member state has requested a referral of the
transaction. If proceedings are initiated, the EC Commission must reach a
decision in the proceedings within four months of the commencement of the
proceedings. If the EC Commission fails to reach a decision within either of
these time periods the transaction will be deemed to be compatible with the
common market.
 
     If the EC Commission declares the Offer and the Proposed Rockwell Merger to
be not compatible with the common market, it may prevent the consummation of the
transaction, order a divestiture if the transaction has already been consummated
or impose conditions or other obligations. In the event that the transaction is
found not to be subject to the EC Merger Regulation, various national merger
control regimes of the member states may apply, resulting in the possibility
that approvals may be necessary from the various national authorities.
 
     There can be no assurance that a challenge to the Offer and the Proposed
Rockwell Merger will not be made pursuant to the EC Merger Regulation or,
alternatively, pursuant to the merger regulations of one or more of the various
member states, or, if such a challenge is made, what the outcome will be. See
Section 14.
 
     Investment Canada Act.  According to publicly available information, the
Company conducts certain operations in Canada. The Investment Canada Act
(Canada) (the "ICA") may require that a notice of the acquisition of "control"
(as defined in the ICA) by a "non-Canadian" (as defined in the ICA) of any
"Canadian business" (as defined in the ICA) be furnished to Investment Canada, a
Canadian governmental agency (the "Agency"), and that certain of these
investments to acquire control of a Canadian business be reviewed and approved
by the Minister of the federal cabinet responsible for the ICA (the "Minister")
as an investment that is "likely to be of net benefit" to Canada based upon
criteria set forth in the ICA. An acquisition of control of a corporation
incorporated outside Canada that controls, directly or indirectly, an entity in
Canada carrying on a Canadian business (an "indirect acquisition") does not
require approval under the ICA before the acquisition is implemented, although
some indirect acquisitions may require approval after implementation. Direct
acquisitions may require the Minister's approval before they can be implemented.
Under the ICA, the acquisition of more than a majority of the voting shares of a
corporation is deemed to be an acquisition of control.
 
     Most indirect acquisitions of control of a Canadian business by an
"American" (as defined in the ICA) are not reviewable under the ICA provided
that the value of the assets of all the acquired entities carrying on a Canadian
business is not more than 50% of the value of the assets of all entities
acquired in the transaction, wherever located. Where the value of the assets of
entities carrying on a Canadian business exceeds that
 
                                       37
<PAGE>   41
 
amount, and in the case of most direct acquisitions of control of a Canadian
business by or from an "American," the transaction is reviewable under the ICA
if the value of the assets of all the acquired entities carrying on a Canadian
business is Cdn. $153 million or more (for transactions implemented at any time
in 1994).
 
     The Purchaser intends to file within the prescribed time period a notice
with respect to the Offer and the Proposed Rockwell Merger with the Agency and
to seek approval of the Minister, if required. If the Purchaser were to acquire
control of a Canadian business in a transaction reviewable under the ICA and,
within certain specified periods of time provided in the ICA, the Minister
decides that he is not satisfied that the acquisition is "likely to be of net
benefit" to Canada, the Minister could issue a notice the effect of which would
be to prohibit the acquisition of "control" of all or part of the Company's
Canadian businesses by the Purchaser, or, where such acquisition has already
been made, to compel divestiture of control of all or part of the Company's
Canadian businesses. In assessing whether a transaction is likely to be of net
benefit to Canada, the ICA requires that the Minister consider any
representations and undertakings that are submitted by an acquiror.
 
     Competition Act (Canada).  Certain provisions of the Competition Act
require pre-merger notification to the Director of Investigation and Research
(the "Canadian Director") of significant transactions, which may include the
acquisition of a large percentage of the stock of a public company which has
Canadian operations, or a merger or amalgamation involving such an entity.
Pre-merger notification is generally required with respect to transactions in
which the parties to the transaction and their affiliates have assets in Canada,
or annual gross revenues from sales in, from or into Canada, in excess of Cdn.
$400 million and which involve the direct or indirect acquisition of an
operating business in Canada of which the value of the Canadian assets, or the
annual gross revenues from sales in or from Canada generated from such assets,
exceed Cdn. $35 million (or, in the case of an amalgamation of two or more
corporations one or more of which carries on an operating business in Canada,
the Canadian assets or the annual gross revenues from sales in or from Canada of
the entity resulting from such amalgamation or the entities controlled by such
entity exceed Cdn. $70 million). In the case of an acquisition of shares of a
public company, the transaction must also result in the acquiror holding voting
shares which carry more than 20% of the outstanding votes (or more than 50% if
the acquiror already holds 20% or more) attached to all the voting shares of the
public company. If a transaction is subject to the pre-merger notification
requirements, notice must be given either 7 or 21 days (depending on the
information required by the Canadian Director) prior to the completion of the
transaction. The Canadian Director may waive or seek an extension of the waiting
period. After the applicable waiting period expires or is waived, the
transaction may be completed.
 
     The Canadian Director may apply to the Competition Tribunal, a specialized
tribunal empowered to deal with certain matters governed by the Competition Act
with respect to a "merger" (as defined in the Competition Act) and, if the
Competition Tribunal finds that the merger prevents or lessens or is likely to
prevent or lessen competition substantially, it may order that the merger not
proceed or, in the event that the merger has been completed, order its
dissolution or the disposition of some or all the assets or shares involved. A
merger may be subjected to an order of the Competition Tribunal whether or not
it is a notifiable transaction. In some instances, the Canadian Director may
issue an "advance ruling certificate" to the effect that he would not have
sufficient grounds on which to apply to the Competition Tribunal under the
merger provisions of the Competition Act or a "no-action" advisory opinion
following a notification or voluntary submission. If the Canadian Director
issues an advance ruling certificate in respect of a proposed transaction, that
transaction is exempt from the pre-merger notification provisions.
 
     The Purchaser intends to file any required notice with respect to the Offer
and the Proposed Rockwell Merger with the Canadian Director and, to the extent
necessary, observe any applicable waiting period.
 
     Other Foreign Approvals.  According to publicly available information, the
Company also owns property and conducts business in a number of other foreign
countries and jurisdictions. In connection with the acquisition of the Shares
pursuant to the Offer or the Proposed Rockwell Merger, the laws of certain of
those foreign countries and jurisdictions may require the filing of information
with, or the obtaining of the approval of, governmental authorities in such
countries and jurisdictions. The governments in such countries and jurisdictions
might attempt to impose additional conditions on the Company's operations
conducted in such
 
                                       38
<PAGE>   42
 
countries and jurisdictions as a result of the acquisition of the Shares
pursuant to the Offer or the Proposed Rockwell Merger. There can be no assurance
that the Purchaser will be able to cause the Company or its subsidiaries to
satisfy or comply with such laws or that compliance or noncompliance will not
have adverse consequences for the Company or any subsidiary after purchase of
the Shares pursuant to the Offer or the Proposed Rockwell Merger.
 
     Connecticut Environmental Transfer Law.  The Connecticut Transfer Act,
Conn. Gen. Stat. Sec. 22a-134 et seq. ("CTA"), requires that prior to the
transfer of ownership of an establishment subject to the CTA, the transferor
must submit a "Negative Declaration" to the transferee stating (i) that there
has been no spillage or discharge of hazardous waste on the property or that any
such spillage or discharge has been cleaned up according to the procedures and
requirements of the state Department of Environmental Protection (the "DEP") and
(ii) that any hazardous waste remaining on-site is being managed in accordance
with all applicable regulations. If the transferor cannot submit a "Negative
Declaration," one of the parties to the transfer must certify to the
Commissioner of the DEP that such party will contain or otherwise mitigate the
effects of any spillage or discharge in accordance with the procedures and
timetable approved by the Commissioner pursuant to an order or consent decree.
Based on publicly available information, the Purchaser understands that the
Company operates a facility in Connecticut. The Purchaser will seek to determine
whether any of the Company's properties are establishments subject to the CTA
and, if so, the Purchaser will comply, or seek to cause the Company to comply,
with the CTA as promptly as practicable following consummation of the Offer. See
Section 14.

renders various investment banking services to Rockwell and its affiliates for
which it is paid customary fees.
 
     Georgeson & Company Inc. has been retained by the Purchaser as Information
Agent in connection with the Offer. The Information Agent may contact holders of
Shares and Rights by mail, telephone, telex, telegraph and personal interview
and may request brokers, dealers and other nominee stockholders to forward
material relating to the Offer to beneficial owners of Shares and Rights. The
Purchaser will pay the Information Agent reasonable and customary compensation
for all such services in addition to reimbursing the Information Agent for
reasonable out-of-pocket expenses in connection therewith. The Purchaser has
agreed to indemnify the Information Agent against certain liabilities and
expenses in connection with the Offer, including certain liabilities under the

Purchaser for customary clerical and mailing expenses incurred by them in
forwarding offering materials to their customers.
 
17. MISCELLANEOUS.  The Offer is not being made to (nor will tenders be accepted
from or on behalf of) holders of Shares or Rights residing in any jurisdiction
in which the making of the Offer or the acceptance thereof would not be in
compliance with the securities, blue sky or other laws of such jurisdiction.
However, the Purchaser may, in its discretion, take such action as it may deem
necessary to make the Offer in any jurisdiction and extend the Offer to holders
of Shares in such jurisdiction.
 
     In any jurisdiction where the securities, blue sky or other laws require
the Offer to be made by a licensed broker or dealer, the Offer will be deemed to
be made on behalf of the Purchaser by the Dealer Manager or one or more
registered brokers or dealers that are licensed under the laws of such
jurisdiction.

     This Letter of Transmittal is to be completed by stockholders either if
certificates for Class A Shares and/or Class A Rights (each as defined in the
Offer to Purchase, dated October 21, 1994 (the "Offer to Purchase")) are to be
forwarded herewith or, unless an Agent's Message (as defined in the Offer to
Purchase) is utilized, if tenders of Class A Shares and/or Class A Rights are to
be made by book-entry transfer to an account maintained by First Chicago Trust
Company of New York (the "Depositary") at The Depository Trust Company ("DTC"),
Midwest Securities Trust Company ("MSTC") or Philadelphia Depository Trust
Company ("PDTC") (each a "Book-Entry Transfer Facility" and collectively
referred to as the "Book-Entry Transfer Facilities"), pursuant to the procedures
set forth in Section 3 of the Offer to Purchase. Stockholders who tender Class A
Shares or Class A Rights by book-entry transfer are referred to herein as
"Book-Entry Stockholders". UNLESS AND UNTIL ROK ACQUISITION CORPORATION (THE
"PURCHASER"), A DELAWARE CORPORATION AND A WHOLLY-OWNED SUBSIDIARY OF ROCKWELL
INTERNATIONAL CORPORATION, A DELAWARE CORPORATION ("ROCKWELL"), DECLARES THAT
THE RIGHTS CONDITION (AS DEFINED IN THE OFFER TO PURCHASE) IS SATISFIED, HOLDERS
OF CLASS A SHARES WILL BE REQUIRED TO TENDER ONE CLASS A RIGHT FOR EACH CLASS A
SHARE TENDERED IN ORDER TO EFFECT A VALID TENDER OF SUCH CLASS A SHARE. If the
Distribution Date (as defined in the Offer to Purchase) does not occur prior to
the Expiration Date (as defined in the Offer to Purchase), a tender of Class A
Shares will also constitute a tender of the associated Class A Rights. If the
Distribution Date occurs and the certificates representing Class A Rights
("Rights Certificates") are distributed by Reliance Electric Company, a Delaware
corporation, to holders of Class A Shares prior to the time a holder's Class A
Shares are tendered pursuant to the Offer (as defined in the Offer to Purchase),
in order for Class A Rights (and the corresponding Class A Shares) to be validly
tendered, Rights Certificates representing a number of Class A Rights equal to
the number of Class A Shares tendered must be delivered to the Depositary or, if
available, a Book-Entry Confirmation (as defined in the Offer to Purchase)
received by the Depositary with respect thereto. If the Distribution Date occurs
and Rights Certificates are not distributed prior to the time Class A Shares are
tendered pursuant to the Offer, Class A Rights may be tendered prior to a
stockholder receiving Rights Certificates by use of the guaranteed delivery
procedure described below. In any case, a tender of Class A Shares constitutes
an agreement by the tendering stockholder to deliver Rights Certificates
representing a number of Class A Rights equal to the number of Class A Shares
tendered pursuant to the Offer to the Depositary within five business days after
the date Rights Certificates are distributed. The Purchaser reserves the right
to require that the Depositary receive Rights Certificates, or a Book-Entry
Confirmation, if available, with respect to such Class A Rights, prior to
accepting the related Class A Shares for payment pursuant to the Offer if the
Distribution Date occurs prior to the Expiration Date. See Section 3 of the
Offer to Purchase.
 
     Holders of Class A Shares and Class A Rights whose certificates for such
Class A Shares (the "Share Certificates") and, if applicable, Rights
Certificates, are not immediately available (including, if the Distribution Date
has occurred, because Rights Certificates have not yet been distributed) or who
cannot deliver their Share Certificates or, if applicable, their Rights
Certificates, and all other required documents to the Depositary on or prior to
the Expiration Date or who cannot complete the procedures for book-entry
transfer on a timely basis, must tender their Class A Shares and Class A Rights
according to the guaranteed delivery procedures set forth in Section 3 of the
Offer to Purchase. See Instruction 2. DELIVERY OF DOCUMENTS TO A BOOK-ENTRY
TRANSFER FACILITY DOES NOT CONSTITUTE DELIVERY TO THE DEPOSITARY.
 
NOTE: SIGNATURES MUST BE PROVIDED ON THE INSIDE AND REVERSE BACK COVER. PLEASE
      READ THE ACCOMPANYING INSTRUCTIONS CAREFULLY.

Ladies and Gentlemen:
 
     The undersigned hereby tenders to ROK Acquisition Corporation (the
"Purchaser"), a Delaware corporation and a wholly-owned subsidiary of Rockwell
International Corporation, a Delaware corporation ("Rockwell"), the above
described shares of Class A Common Stock, par value $.01 per share (the "Class A
Shares"), of Reliance Electric Company, a Delaware corporation (the "Company"),
and (unless and until the Purchaser declares that the Rights Condition (as
defined in the Offer to Purchase) has been satisfied) the associated Series A
Preferred Stock purchase rights (the "Class A Rights") issued pursuant to the
Rights Agreement dated as of August 29, 1994 between the Company and Society
National Bank, as Rights Agent (as the same may be amended, the "Rights
Agreement"), at a price of $30 per Class A Share (and associated Class A Right),
net to the seller in cash, without interest thereon, upon the terms and subject
to the conditions set forth in the Offer to Purchase, dated October 21, 1994
(the "Offer to Purchase"), receipt of which is hereby acknowledged, and in this
Letter of Transmittal (which together with the Offer to Purchase constitute the
"Offer"). Unless the context otherwise requires, all references to Class A
Shares shall include the Class A Rights and all references to the Class A Rights
shall include all benefits that may inure to the holders of the Class A Rights
pursuant to the Rights Agreement. The undersigned understands that the Purchaser
reserves the right to transfer or assign, in whole or from time to time in part,
to one or more of its subsidiaries or affiliates the right to purchase all or
any portion of the Class A Shares and Class A Rights tendered pursuant to the
Offer.
 
     Subject to, and effective upon, acceptance for payment of and payment for
the Class A Shares and Class A Rights tendered herewith in accordance with the
terms and subject to the conditions of the Offer, the undersigned hereby sells,
assigns, and transfers to, or upon the order of, the Purchaser all right, title
and interest in and to all of the Class A Shares and Class A Rights that are
being tendered hereby and any and all dividends on the Class A Shares or any
distribution (including, without limitation, the issuance of additional Class A
Shares pursuant to a stock dividend or stock split, the issuance of other
securities or the issuance of rights (other than the separation of the Class A
Rights from the Class A Shares) for the purchase of any securities) with respect
to the Class A Shares or Class A Rights (other than the Redemption Price (as
defined in the Offer to Purchase)) that is declared or paid by the Company on or
after August 30, 1994 and is payable or distributable to stockholders of record
on a date prior to the transfer into the name of the Purchaser or its nominees
or transferees on the Company's stock transfer records of the Class A Shares and
Class A Rights purchased pursuant to the Offer (except that if the Class A
Rights are redeemed by the Company's Board of Directors, tendering stockholders
who are holders of record as of the applicable record date will be entitled to
receive and retain the Redemption Price) (a "Distribution"), and constitutes and
irrevocably appoints the Depositary the true and lawful agent, attorney-in-fact
and proxy of the undersigned to the full extent of the undersigned's rights with
respect to such Class A Shares and Class A Rights (and any Distributions) with
full power of substitution (such power of attorney and proxy being deemed to be
an irrevocable power coupled with an interest), to (a) deliver Share
Certificates and Rights Certificates (and any Distributions), or transfer
ownership of such Class A Shares or Class A Rights on the account books
maintained by the Book-Entry Transfer Facilities, together in either such case
with all accompanying evidences of transfer and authenticity, to or upon the
order of the Purchaser upon receipt by the Depositary, as the undersigned's
agent, of the purchase price, (b) present such Class A Shares and Class A Rights
(and any Distributions) for transfer on the books of the Company and (c) receive
all benefits and otherwise exercise all rights of beneficial ownership of such
Class A Shares and Class A Rights (and any Distributions), all in accordance
with the terms of the Offer.
 
     The undersigned understands that if the Distribution Date (as defined in
the Offer to Purchase) has occurred and Rights Certificates have been
distributed by the Company to holders of Class A Shares prior to the time Class
A Shares are tendered herewith, in order for Class A Rights (and the
corresponding Class A Shares) to be validly tendered, Rights Certificates
representing a number of Class A Rights equal to the number of Class A Shares
being tendered herewith must be delivered to the Depositary or, if available, a
Book-Entry Confirmation (as defined in Instruction 2) must be received by the
Depositary with respect thereto. If the Distribution Date has occurred and
Rights Certificates have not been distributed prior to the time Class A Shares
and Class A Rights are tendered herewith, the undersigned agrees to deliver
Rights
 
                                        5
<PAGE>   6
 
Certificates representing a number of Class A Rights equal to the number of
Class A Shares tendered herewith to the Depositary within five business days
after the date such Rights Certificates are distributed. The undersigned
understands that if the Rights Condition is not satisfied, the Purchaser
reserves the right to require that the Depositary receive Rights Certificates,
or a Book-Entry Confirmation, if available, with respect to such Class A Rights,
prior to accepting the related Class A Shares for payment, if the Distribution
Date occurs prior to the Expiration Date. In that event, payment for Class A
Shares tendered and accepted for payment pursuant to the Offer will be made only
after timely receipt by the Depositary of, among other things, such Rights
Certificates.
 
     The undersigned hereby irrevocably appoints Charles H. Harff and William J.
Calise, Jr., and each of them, the attorneys-in-fact and proxies of the
undersigned, each with full power of substitution, to vote in such manner as
each such attorney and proxy or his substitute shall, in his sole discretion,
deem proper, and otherwise act (including pursuant to written consent) with
respect to all of the Class A Shares and Class A Rights tendered hereby which
have been accepted for payment by the Purchaser prior to the time of such vote
or action (and any Distributions) which the undersigned is entitled to vote at
any meeting of stockholders (whether annual or special and whether or not an
adjourned meeting) of the Company, or by written consent in lieu of such
meeting, or otherwise. This power of attorney and proxy is coupled with an
interest in the Company and in the Class A Shares and Class A Rights and is
irrevocable and is granted in consideration of, and is effective upon, the
acceptance for payment of such Class A Shares and Class A Rights by the
Purchaser in accordance with the terms of the Offer. Such acceptance for payment
shall revoke, without further action, any other power of attorney or proxy
granted by the undersigned at any time with respect to such Class A Shares and
Class A Rights (and any Distributions) and no subsequent powers of attorney or
proxies will be given (and if given will be deemed not to be effective) with
respect thereto by the undersigned. The undersigned understands that the
Purchaser reserves the right to require that, in order for Class A Shares and
Class A Rights to be deemed validly tendered, immediately upon the Purchaser's
acceptance for payment of such Class A Shares and Class A Rights, the Purchaser
is able to exercise full voting rights with respect to such Class A Shares,
Class A Rights and other securities, including voting at any meeting of
stockholders.
 
     The undersigned hereby represents and warrants that the undersigned has
full power and authority to tender, sell, assign and transfer the Class A Shares
and Class A Rights tendered hereby (and any Distributions) and that, when the
same are accepted for payment by the Purchaser, the Purchaser will acquire good,
marketable and unencumbered title thereto, free and clear of all liens,
restrictions, charges and encumbrances and the same will not be subject to any
adverse claim. The undersigned, upon request, will execute and deliver any
additional documents deemed by the Depositary or the Purchaser to be necessary
or desirable to complete the sale, assignment and transfer of the Class A Shares
and Class A Rights tendered hereby (and any Distributions). In addition, the
undersigned shall promptly remit and transfer to the Depositary for the account
of the Purchaser any and all other Distributions in respect of the Class A
Shares and Class A Rights tendered hereby, accompanied by appropriate
documentation of transfer and, pending such remittance or appropriate assurance
thereof, the Purchaser shall be entitled to all rights and privileges as owner
of any such Distributions, and may withhold the entire purchase price or deduct
from the purchase price of Class A Shares and Class A Rights tendered hereby the
amount or value thereof, as determined by the Purchaser in its sole discretion.
 
     All authority herein conferred or herein agreed to be conferred shall not
be affected by, and shall survive, the death or incapacity of the undersigned
and any obligation of the undersigned hereunder shall be binding upon the heirs,
executors, administrators, legal representatives, successors and assigns of the
undersigned. Except as stated in the Offer to Purchase, this tender is
irrevocable.
 
     The undersigned understands that tenders of Class A Shares and Class A
Rights pursuant to any one of the procedures described in Section 3 of the Offer
to Purchase and in the instructions hereto will constitute a binding agreement
between the undersigned and the Purchaser upon the terms and subject to the
conditions of the Offer.
 
     Unless otherwise indicated herein under "Special Payment Instructions,"
please issue the check for the purchase price and/or return any Share
Certificates or Rights Certificates not tendered or accepted for
 
                                        6

payment in the name(s) of the undersigned. Similarly, unless otherwise indicated
under "Special Delivery Instructions," please mail the check for the purchase
price and/or return any Share Certificates or Rights Certificates not tendered
or accepted for payment (and accompanying documents, as appropriate) to the
undersigned at the address shown below the undersigned's signature. In the event

Instructions" are completed, please issue the check for the purchase price
and/or return any Share Certificates or Rights Certificates not tendered or
accepted for payment in the name(s) of, and deliver said check and/or return
certificates to, the person or persons so indicated. Stockholders tendering

Class A Shares or Class A Rights not accepted for payment be returned by
crediting such account maintained at such Book-Entry Transfer Facility as such
stockholder may designate by making an appropriate entry under "Special Payment
Instructions." The undersigned recognizes that the Purchaser has no obligation
pursuant to the "Special Payment Instructions" to transfer any Class A Shares
and Class A Rights from the name of the registered holder thereof if the
Purchaser does not accept for payment any of such Class A Shares and Class A
Rights.

facsimile hereof), with any required signature guarantees (or, in the case of a
book-entry delivery, an Agent's Message) and any other documents required by
this Letter of Transmittal, must be received by the Depositary within (x) in the

any other required information should be listed on a separate schedule attached

TRANSFER.)  If fewer than all the Class A Shares or Class A Rights evidenced by
any certificate submitted are to be tendered, fill in the number of Class A
Shares or Class A Rights which are to be tendered in the box entitled "Number of

capacity, such persons should so indicate when signing, and proper evidence
satisfactory to the Purchaser of their authority so to act must be submitted.
 
     When this Letter of Transmittal is signed by the registered owner(s) of the
Class A Shares or Class A Rights listed and transmitted hereby, no endorsements
of certificates or separate stock powers are required unless payment is to be
made to or certificates for Class A Shares or Class A Rights not tendered or
purchased are to be issued in the name of a person other than the registered
owner(s). Signatures on such certificates or stock powers must be guaranteed by
an Eligible Institution.
 
     If this Letter of Transmittal is signed by a person other than the
registered owner(s) of the Class A Shares or Class A Rights listed, the
certificates must be endorsed or accompanied by appropriate stock powers, in
either case signed exactly as the name or names of the registered owner(s)
appear(s) on the certificates. Signatures on such certificates or stock powers
must be guaranteed by an Eligible Institution.

to, or if certificates for Class A Shares not tendered or purchased are to be
registered in the name of, any person other than the registered holder, or if
tendered certificates are registered in the name of any person other than the
person(s) signing this Letter of Transmittal, the amount of any stock transfer
taxes (whether imposed on the registered holder or such person) payable on
account of the transfer to such person will be deducted from the purchase price
unless satisfactory evidence of the payment of such taxes or exemption therefrom
is submitted.
 
     EXCEPT AS PROVIDED IN THIS INSTRUCTION 6, IT WILL NOT BE NECESSARY FOR
TRANSFER TAX STAMPS TO BE AFFIXED TO THE CERTIFICATES LISTED IN THIS LETTER OF
TRANSMITTAL.
 
     7. SPECIAL PAYMENT AND DELIVERY INSTRUCTIONS.  If a check is to be issued
in the name of and/or certificates for unpurchased Class A Shares or Class A
Rights are to be returned to a person other than the signer of this Letter of
Transmittal or if a check is to be sent and/or such certificates are to be
returned to someone other than the signer of this Letter of Transmittal or to an
address other than that shown on the front cover hereof, the appropriate boxes
on this Letter of Transmittal should be completed. Stockholders tendering Class
A Shares or Class A Rights by book-entry transfer may request that Class A
Shares or Class A Rights not purchased be credited to such account maintained at
such Book-Entry Transfer Facility as such stockholder may designate hereon. If
no such instructions are given, such Class A Shares or Class A Rights not
purchased will be returned by crediting the account at the Book-Entry Transfer
Facility designated above. See Instruction 1.
 
     8. REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.  Requests for assistance
may be directed to the Information Agent at its addresses set forth below.
Requests for additional copies of the Offer to Purchase and this Letter of
Transmittal may be directed to the Information Agent or to brokers, dealers,
commercial banks or trust companies.
 
     9. 31% BACKUP WITHHOLDING; SUBSTITUTE FORM W-9.  Under U.S. Federal income
tax law, a stockholder whose tendered Class A Shares are accepted for payment is
required to provide the Depositary with such stockholder's correct taxpayer
identification number ("TIN") on Substitute Form W-9 below. If the Depositary is
not provided with the correct TIN, the Internal Revenue Service may subject the
stockholder or other payee to a $50 penalty. In addition, payments that are made
to such stockholder or other payee with respect to Class A Shares or Class A
Rights purchased pursuant to the Offer may be subject to 31% backup withholding.
 
     Certain stockholders (including, among others, all corporations and certain
foreign individuals) are not subject to these backup withholding and reporting
requirements. In order for a foreign individual to qualify as an exempt
recipient, the stockholder must submit a Form W-8, signed under penalties of
perjury, attesting to that individual's exempt status. A Form W-8 can be
obtained from the Depositary. See the enclosed "Guidelines for Certification of
Taxpayer Identification Number on Substitute Form W-9" for more instructions.
 
     If backup withholding applies, the Depositary is required to withhold 31%
of any such payments made to the stockholder or other payee. Backup withholding
is not an additional tax. Rather, the tax liability of persons subject to backup
withholding will be reduced by the amount of tax withheld. If withholding
results in an overpayment of taxes, a refund may be obtained from the Internal
Revenue Service.
 
     The box in Part 3 of the Substitute Form W-9 may be checked if the
tendering stockholder has not been issued a TIN and has applied for a TIN or
intends to apply for a TIN in the near future. If the box in Part 3 is checked,
the stockholder or other payee must also complete the Certificate of Awaiting
Taxpayer Identification Number below in order to avoid backup withholding.
Notwithstanding that the box in Part 3 is checked and the Certificate of
Awaiting Taxpayer Identification Number is completed, the Depositary will
withhold 31% of all payments made prior to the time a properly certified TIN is
provided to the Depositary.
 
     The stockholder is required to give the Depositary the TIN (e.g., social
security number or employer identification number) of the record owner of the
Class A Shares or Class A Rights or of the last transferee appearing on the
transfers attached to, or endorsed on, the Class A Shares or Class A Rights. If
the Class A
 
                                       12
<PAGE>   13
 
Shares or Class A Rights are in more than one name or are not in the name of the
actual owner, consult the enclosed "Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9" for additional guidance on which
number to report.
 
     10. LOST, DESTROYED OR STOLEN CERTIFICATES.  If any certificate(s)
representing Class A Shares or Class A Rights has been lost, destroyed or
stolen, the stockholder should promptly notify the Depositary. The stockholder
will then be instructed as to the steps that must be taken in order to replace
the certificate(s). This Letter of Transmittal and related documents cannot be
processed until the procedures for replacing lost or destroyed certificates have
been followed.
 
     IMPORTANT: THIS LETTER OF TRANSMITTAL (OR A FACSIMILE COPY HEREOF) OR AN
AGENT'S MESSAGE TOGETHER WITH CERTIFICATES OR CONFIRMATION OF BOOK-ENTRY
TRANSFER AND ALL OTHER REQUIRED DOCUMENTS MUST BE RECEIVED BY THE DEPOSITARY ON
OR PRIOR TO THE EXPIRATION DATE.

 you received another notification from the IRS that you are no longer subject

     This Letter of Transmittal is to be completed by stockholders to tender
certificates for Class B Shares and/or Class B Rights (each as defined in the
Offer to Purchase, dated October 21, 1994 (the "Offer to Purchase")). UNLESS AND
UNTIL ROK ACQUISITION CORPORATION (THE "PURCHASER"), A DELAWARE CORPORATION AND
A WHOLLY-OWNED SUBSIDIARY OF ROCKWELL INTERNATIONAL CORPORATION, A DELAWARE
CORPORATION ("ROCKWELL"), DECLARES THAT THE RIGHTS CONDITION (AS DEFINED IN THE
OFFER TO PURCHASE) IS SATISFIED, HOLDERS OF CLASS B SHARES WILL BE REQUIRED TO
TENDER ONE CLASS B RIGHT FOR EACH CLASS B SHARE TENDERED IN ORDER TO EFFECT A
VALID TENDER OF SUCH CLASS B SHARE. If the Distribution Date (as defined in the
Offer to Purchase) does not occur prior to the Expiration Date (as defined in
the Offer to Purchase), a tender of Class B Shares will also constitute a tender
of the associated Class B Rights. If the Distribution Date occurs and the
certificates representing Class B Rights ("Rights Certificates") are distributed
by Reliance Electric Company, a Delaware corporation, to holders of Class B
Shares prior to the time a holder's Class B Shares are tendered pursuant to the
Offer (as defined in the Offer to Purchase), in order for Class B Rights (and
the corresponding Class B Shares) to be validly tendered, Rights Certificates
representing a number of Class B Rights equal to the number of Class B Shares
tendered must be delivered to the Depositary. If the Distribution Date occurs
and Rights Certificates are not distributed prior to the time Class B Shares are
tendered pursuant to the Offer, Class B Rights may be tendered prior to a
stockholder receiving Rights Certificates by use of the guaranteed delivery
procedure described below. In any case, a tender of Class B Shares constitutes
an agreement by the tendering stockholder to deliver Rights Certificates
representing a number of Class B Rights equal to the number of Class B Shares
tendered pursuant to the Offer to the Depositary within five business days after
the date Rights Certificates are distributed. The Purchaser reserves the right
to require that the Depositary receive Rights Certificates with respect to such
Class B Rights prior to accepting the related Class B Shares for payment
pursuant to the Offer if the Distribution Date occurs prior to the Expiration
Date. See Section 3 of the Offer to Purchase.
 
     Holders of Class B Shares and Class B Rights whose certificates for such
Class B Shares (the "Share Certificates") and, if applicable, Rights
Certificates, are not immediately available (including, if the Distribution Date
has occurred, because Rights Certificates have not yet been distributed) or who
cannot deliver their Share Certificates or, if applicable, their Rights
Certificates, and all other required documents to the Depositary on or prior to
the Expiration Date, must tender their Class B Shares and Class B Rights
according to the guaranteed delivery procedures set forth in Section 3 of the
Offer to Purchase. See Instruction 2.
 
NOTE: SIGNATURES MUST BE PROVIDED ON THE INSIDE AND REVERSE BACK COVER. PLEASE

Ladies and Gentlemen:
 
     The undersigned hereby tenders to ROK Acquisition Corporation (the
"Purchaser"), a Delaware corporation and a wholly-owned subsidiary of Rockwell
International Corporation, a Delaware corporation ("Rockwell"), the above
described shares of Class B Common Stock, par value $.01 per share (the "Class B
Shares"), of Reliance Electric Company, a Delaware corporation (the "Company"),
and (unless and until the Purchaser declares that the Rights Condition (as
defined in the Offer to Purchase) has been satisfied) the associated Series B
Preferred Stock purchase rights (the "Class B Rights") issued pursuant to the
Rights Agreement dated as of August 29, 1994 between the Company and Society
National Bank, as Rights Agent (as the same may be amended, the "Rights
Agreement"), at a price of $30 per Class B Share (and associated Class B Right),
net to the seller in cash, without interest thereon, upon the terms and subject
to the conditions set forth in the Offer to Purchase, dated October 21, 1994
(the "Offer to Purchase"), receipt of which is hereby acknowledged, and in this
Letter of Transmittal (which together with the Offer to Purchase constitute the
"Offer"). Unless the context otherwise requires, all references to Class B
Shares shall include the Class B Rights and all references to the Class B Rights
shall include all benefits that may inure to the holders of the Class B Rights
pursuant to the Rights Agreement. The undersigned understands that the Purchaser
reserves the right to transfer or assign, in whole or from time to time in part,
to one or more of its subsidiaries or affiliates the right to purchase all or
any portion of the Class B Shares and Class B Rights tendered pursuant to the
Offer.
 
     Subject to, and effective upon, acceptance for payment of and payment for
the Class B Shares and Class B Rights tendered herewith in accordance with the
terms and subject to the conditions of the Offer, the undersigned hereby sells,
assigns, and transfers to, or upon the order of, the Purchaser all right, title
and interest in and to all of the Class B Shares and Class B Rights that are
being tendered hereby and any and all dividends on the Class B Shares or any
distribution (including, without limitation, the issuance of additional Class B
Shares pursuant to a stock dividend or stock split, the issuance of other
securities or the issuance of rights (other than the separation of the Class B
Rights from the Class B Shares) for the purchase of any securities) with respect
to the Class B Shares or Class B Rights (other than the Redemption Price (as
defined in the Offer to Purchase)) that is declared or paid by the Company on or
after August 30, 1994 and is payable or distributable to stockholders of record
on a date prior to the transfer into the name of the Purchaser or its nominees
or transferees on the Company's stock transfer records of the Class B Shares and
Class B Rights purchased pursuant to the Offer (except that if the Class B
Rights are redeemed by the Company's Board of Directors, tendering stockholders
who are holders of record as of the applicable record date will be entitled to
receive and retain the Redemption Price) (a "Distribution"), and constitutes and
irrevocably appoints the Depositary the true and lawful agent, attorney-in-fact
and proxy of the undersigned to the full extent of the undersigned's rights with
respect to such Class B Shares and Class B Rights (and any Distributions) with
full power of substitution (such power of attorney and proxy being deemed to be
an irrevocable power coupled with an interest), to (a) deliver Share
Certificates and Rights Certificates (and any Distributions), together with all
accompanying evidences of transfer and authenticity, to or upon the order of the
Purchaser upon receipt by the Depositary, as the undersigned's agent, of the
purchase price, (b) present such Class B Shares and Class B Rights (and any
Distributions) for transfer on the books of the Company, (c) if directed by the
Purchaser, present Share Certificates (and any Distributions), together with any
required notice, for conversion on behalf of the undersigned into shares of
Class A Common Stock, par value $.01 per share ("Class A Shares"), of the
Company (and any dividends or distributions ("Class A Distributions") into which
a Distribution is convertible) and then to present the Class A Shares (and Class
A Distributions) into which such Class B Shares (and Distributions) were
converted for transfer on the books of the Company, and (d) receive all benefits
and otherwise exercise all rights of beneficial ownership of such Class B Shares
and Class B Rights (and any Distributions) or the Class A Shares (and any Class
A Distributions) into which they were converted, all in accordance with the
terms of the Offer.
 
     The undersigned understands that if the Distribution Date (as defined in
the Offer to Purchase) has occurred and Rights Certificates have been
distributed by the Company to holders of Class B Shares prior to the time Class
B Shares are tendered herewith, in order for Class B Rights (and the
corresponding Class B Shares) to be validly tendered, Rights Certificates
representing a number of Class B Rights equal to the
 
                                        5
<PAGE>   6
 
number of Class B Shares being tendered herewith must be delivered to the
Depositary. If the Distribution Date has occurred and Rights Certificates have
not been distributed prior to the time Class B Shares and Class B Rights are
tendered herewith, the undersigned agrees to deliver Rights Certificates
representing a number of Class B Rights equal to the number of Class B Shares
tendered herewith to the Depositary within five business days after the date
such Rights Certificates are distributed. The undersigned understands that if
the Rights Condition is not satisfied, the Purchaser reserves the right to
require that the Depositary receive Rights Certificates with respect to such
Class B Rights prior to accepting the related Class B Shares for payment, if the
Distribution Date occurs prior to the Expiration Date. In that event, payment
for Class B Shares tendered and accepted for payment pursuant to the Offer will
be made only after timely receipt by the Depositary of, among other things, such
Rights Certificates.
 
     The undersigned hereby irrevocably appoints Charles H. Harff and William J.
Calise, Jr., and each of them, the attorneys-in-fact and proxies of the
undersigned, each with full power of substitution, to vote in such manner as
each such attorney and proxy or his substitute shall, in his sole discretion,
deem proper, and otherwise act (including pursuant to written consent) with
respect to all of the Class B Shares and Class B Rights tendered hereby which
have been accepted for payment by the Purchaser prior to the time of such vote
or action (and any Distributions) which the undersigned is entitled to vote at
any meeting of stockholders (whether annual or special and whether or not an
adjourned meeting) of the Company, or by written consent in lieu of such
meeting, or otherwise. This power of attorney and proxy is coupled with an
interest in the Company and in the Class B Shares and Class B Rights and is
irrevocable and is granted in consideration of, and is effective upon, the
acceptance for payment of such Class B Shares and Class B Rights by the
Purchaser in accordance with the terms of the Offer. Such acceptance for payment
shall revoke, without further action, any other power of attorney or proxy
granted by the undersigned at any time with respect to such Class B Shares and
Class B Rights (and any Distributions) and no subsequent powers of attorney or
proxies will be given (and if given will be deemed not to be effective) with
respect thereto by the undersigned. The undersigned understands that the
Purchaser reserves the right to require that, in order for Class B Shares and
Class B Rights to be deemed validly tendered, immediately upon the Purchaser's
acceptance for payment of such Class B Shares and Class B Rights, the Purchaser
is able to exercise full voting rights with respect to such Class B Shares,
Class B Rights and other securities, including voting at any meeting of
stockholders. In addition, this power of attorney and proxy applies to any Class
A Shares (and Class A Distributions) into which Class B Shares (and
Distributions) have been converted.
 
     The undersigned hereby represents and warrants that the undersigned has
full power and authority to tender, sell, assign and transfer the Class B Shares
and Class B Rights tendered hereby (and any Distributions) and that, when the
same are accepted for payment by the Purchaser, the Purchaser will acquire good,
marketable and unencumbered title thereto, free and clear of all liens,
restrictions, charges and encumbrances and the same will not be subject to any
adverse claim. The undersigned, upon request, will execute and deliver any
additional documents deemed by the Depositary or the Purchaser to be necessary
or desirable to complete the sale, assignment and transfer of the Class B Shares
and Class B Rights tendered hereby (and any Distributions). In addition, the
undersigned shall promptly remit and transfer to the Depositary for the account
of the Purchaser any and all other Distributions in respect of the Class B
Shares and Class B Rights tendered hereby, accompanied by appropriate
documentation of transfer and, pending such remittance or appropriate assurance
thereof, the Purchaser shall be entitled to all rights and privileges as owner
of any such Distributions, and may withhold the entire purchase price or deduct
from the purchase price of Class B Shares and Class B Rights tendered hereby the
amount or value thereof, as determined by the Purchaser in its sole discretion.
 
     All authority herein conferred or herein agreed to be conferred shall not
be affected by, and shall survive, the death or incapacity of the undersigned
and any obligation of the undersigned hereunder shall be binding upon the heirs,
executors, administrators, legal representatives, successors and assigns of the
undersigned. Except as stated in the Offer to Purchase, this tender is
irrevocable.
 
     The undersigned understands that tenders of Class B Shares and Class B
Rights pursuant to any one of the procedures described in Section 3 of the Offer
to Purchase and in the instructions hereto will constitute a
 
                                        6
<PAGE>   7
 
binding agreement between the undersigned and the Purchaser upon the terms and
subject to the conditions of the Offer.
 
     Unless otherwise indicated herein under "Special Payment Instructions,"
please issue the check for the purchase price and/or return any Share
Certificates or Rights Certificates not tendered or accepted for payment in the
name(s) of the undersigned. Similarly, unless otherwise indicated under "Special
Delivery Instructions," please mail the check for the purchase price and/or

Certificates or Rights Certificates not tendered or accepted for payment in the

obligation pursuant to the "Special Payment Instructions" to transfer any Class
B Shares and Class B Rights from the name of the registered holder thereof if
the Purchaser does not accept for payment any of such Class B Shares and Class B
Rights.

registered owner(s) of the Class B Shares or Class B Rights listed, the
certificates must be endorsed or accompanied by appropriate stock powers, in
either case signed exactly as the name or names of the registered owner(s)
appear(s) on the certificates. Signatures on such certificates or stock powers
must be guaranteed by an Eligible Institution.
 
     6. STOCK TRANSFER TAXES.  Except as set forth in this Instruction 6, the
Purchaser will pay or cause to be paid any stock transfer taxes with respect to
the transfer and sale of purchased Class B Shares to it or its order pursuant to
the Offer. If, however, payment of the purchase price is to be made to, or if
certificates for Class B Shares not tendered or purchased are to be registered
in the name of, any person other than the registered holder, or if tendered
certificates are registered in the name of any person other than the person(s)
signing this Letter of Transmittal, the amount of any stock transfer taxes
(whether imposed on the registered holder or such person) payable on account of
the transfer to such person will be deducted from the purchase price unless
satisfactory evidence of the payment of such taxes or exemption therefrom is
submitted.
 
     EXCEPT AS PROVIDED IN THIS INSTRUCTION 6, IT WILL NOT BE NECESSARY FOR
TRANSFER TAX STAMPS TO BE AFFIXED TO THE CERTIFICATES LISTED IN THIS LETTER OF
TRANSMITTAL.
 
     7. SPECIAL PAYMENT AND DELIVERY INSTRUCTIONS.  If a check is to be issued
in the name of and/or certificates for unpurchased Class B Shares or Class B
Rights are to be returned to a person other than the signer of this Letter of
Transmittal or if a check is to be sent and/or such certificates are to be
returned to

someone other than the signer of this Letter of Transmittal or to an address
other than that shown on the front cover hereof, the appropriate boxes on this
Letter of Transmittal should be completed. See Instruction 1.
 
     8. REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.  Requests for assistance
may be directed to the Information Agent at its addresses set forth below.
Requests for additional copies of the Offer to Purchase and this Letter of
Transmittal may be directed to the Information Agent or to brokers, dealers,
commercial banks or trust companies.
 
     9. 31% BACKUP WITHHOLDING; SUBSTITUTE FORM W-9.  Under U.S. Federal income
tax law, a stockholder whose tendered Class B Shares are accepted for payment is
required to provide the Depositary with such stockholder's correct taxpayer
identification number ("TIN") on Substitute Form W-9 below. If the Depositary is
not provided with the correct TIN, the Internal Revenue Service may subject the
stockholder or other payee to a $50 penalty. In addition, payments that are made
to such stockholder or other payee with respect to Class B Shares or Class B
Rights purchased pursuant to the Offer may be subject to 31% backup withholding.
 
     Certain stockholders (including, among others, all corporations and certain
foreign individuals) are not subject to these backup withholding and reporting
requirements. In order for a foreign individual to qualify as an exempt
recipient, the stockholder must submit a Form W-8, signed under penalties of
perjury, attesting to that individual's exempt status. A Form W-8 can be
obtained from the Depositary. See the enclosed "Guidelines for Certification of
Taxpayer Identification Number on Substitute Form W-9" for more instructions.
 
     If backup withholding applies, the Depositary is required to withhold 31%
of any such payments made to the stockholder or other payee. Backup withholding
is not an additional tax. Rather, the tax liability of persons subject to backup
withholding will be reduced by the amount of tax withheld. If withholding
results in an overpayment of taxes, a refund may be obtained from the Internal
Revenue Service.
 
     The box in Part 3 of the Substitute Form W-9 may be checked if the
tendering stockholder has not been issued a TIN and has applied for a TIN or
intends to apply for a TIN in the near future. If the box in Part 3 is checked,
the stockholder or other payee must also complete the Certificate of Awaiting
Taxpayer Identification Number below in order to avoid backup withholding.
Notwithstanding that the box in Part 3 is checked and the Certificate of
Awaiting Taxpayer Identification Number is completed, the Depositary will
withhold 31% of all payments made prior to the time a properly certified TIN is
provided to the Depositary.
 
     The stockholder is required to give the Depositary the TIN (e.g., social
security number or employer identification number) of the record owner of the
Class B Shares or Class B Rights or of the last transferee appearing on the
transfers attached to, or endorsed on, the Class B Shares or Class B Rights. If
the Class B Shares or Class B Rights are in more than one name or are not in the
name of the actual owner, consult the enclosed "Guidelines for Certification of
Taxpayer Identification Number on Substitute Form W-9" for additional guidance
on which number to report.
 
     10. LOST, DESTROYED OR STOLEN CERTIFICATES.  If any certificate(s)
representing Class B Shares or Class B Rights has been lost, destroyed or
stolen, the stockholder should promptly notify the Depositary. The stockholder
will then be instructed as to the steps that must be taken in order to replace
the certificate(s). This Letter of Transmittal and related documents cannot be
processed until the procedures for replacing lost or destroyed certificates have
been followed.
 
     IMPORTANT: THIS LETTER OF TRANSMITTAL (OR A FACSIMILE COPY HEREOF) TOGETHER
WITH CERTIFICATES AND ALL OTHER REQUIRED DOCUMENTS MUST BE RECEIVED BY THE
DEPOSITARY ON OR PRIOR TO THE EXPIRATION DATE.

 CERTIFICATION INSTRUCTIONS -- You must cross out item (2) above if you have

        This Letter of Transmittal is to be completed by stockholders to tender
certificates for Class C Shares and/or Class C Rights (each as defined in the
Offer to Purchase, dated October 21, 1994 (the "Offer to Purchase")). UNLESS AND
UNTIL ROK ACQUISITION CORPORATION (THE "PURCHASER"), A DELAWARE CORPORATION AND
A WHOLLY-OWNED SUBSIDIARY OF ROCKWELL INTERNATIONAL CORPORATION, A DELAWARE
CORPORATION ("ROCKWELL"), DECLARES THAT THE RIGHTS CONDITION (AS DEFINED IN THE
OFFER TO PURCHASE) IS SATISFIED, HOLDERS OF CLASS C SHARES WILL BE REQUIRED TO
TENDER ONE CLASS C RIGHT FOR EACH CLASS C SHARE TENDERED IN ORDER TO EFFECT A
VALID TENDER OF SUCH CLASS C SHARE.  If the Distribution Date (as defined in the
Offer to Purchase) does not occur prior to the Expiration Date (as defined in
the Offer to Purchase), a tender of Class C Shares will also constitute a tender
of the associated Class C Rights.  If the Distribution Date occurs and the
certificates representing Class C Rights ("Rights Certificates") are distributed
by Reliance Electric Company, a Delaware corporation, to holders of Class C
Shares prior to the time a holder's Class C Shares are tendered pursuant to the
Offer (as defined in the Offer to Purchase), in order for Class C Rights (and
the corresponding Class C Shares) to be validly tendered, Rights Certificates
representing a number of Class C Rights equal to the number of Class C Shares
tendered must be delivered to the Depositary.  If the Distribution Date occurs
and Rights Certificates are not distributed prior to the time Class C Shares are
tendered pursuant to the Offer, Class C Rights may be tendered prior to a
stockholder receiving Rights Certificates by use of the guaranteed delivery
procedure described below.  In any case, a tender of Class C Shares constitutes
an agreement by the tendering stockholder to deliver Rights Certificates
representing a number of Class C Rights equal to the number of Class C Shares
tendered pursuant to the Offer to the Depositary within five business days after
the date Rights Certificates are distributed.  The Purchaser reserves the right
to require that the Depositary receive Rights Certificates with respect to such
Class C Rights prior to accepting the related Class C Shares for payment
pursuant to the Offer if the Distribution Date occurs prior to the Expiration
Date.  See Section 3 of the Offer to Purchase.

        
         Holders of Class C Shares and Class C Rights whose certificates
for such Class C Shares (the "Share Certificates") and, if applicable, Rights
Certificates, are not immediately available (including, if the Distribution
Date has occurred, because Rights Certificates have not yet been distributed)
or who cannot deliver their Share

Certificates or, if applicable, their Rights Certificates, and all other
required documents to the Depositary on or prior to the Expiration Date, must

delivery procedures set forth in Section 3 of the Offer to Purchase.  See
Instruction 2.

Ladies and Gentlemen:

        The undersigned hereby tenders to ROK Acquisition Corporation (the
"Purchaser"), a Delaware corporation and a wholly-owned subsidiary of Rockwell
International Corporation, a Delaware corporation ("Rockwell"), the above
described shares of Class C Common Stock, par value $.01 per share (the "Class
C Shares"), of Reliance Electric Company, a Delaware corporation (the
"Company"), and (unless and until the Purchaser declares that the Rights
Condition (as defined in the Offer to Purchase) has been satisfied) the
associated Series C Preferred Stock purchase rights (the "Class C Rights")
issued pursuant to the Rights Agreement dated as of August 29, 1994 between the
Company and Society National Bank, as Rights Agent (as the same may be amended,
the "Rights Agreement"), at a price of $81.24 per Class C Share (and associated
Class C Right), net to the seller in cash, without interest thereon, upon the
terms and subject to the conditions set forth in the Offer to Purchase, dated
October 21, 1994 (the "Offer to Purchase"), receipt of which is hereby
acknowledged, and in this Letter of Transmittal (which together with the Offer
to Purchase constitute the "Offer"). Unless the context otherwise requires, all
references to Class C Shares shall include the Class C Rights and all
references to the Class C Rights shall include all benefits that may inure to
the holders of the Class C Rights pursuant to the Rights Agreement.  The
undersigned understands that the Purchaser reserves the right to transfer or
assign, in whole or from time to time in part, to one or more of its
subsidiaries or affiliates the right to purchase all or any portion of the
Class C Shares and Class C Rights tendered pursuant to the Offer.

        Subject to, and effective upon, acceptance for payment of and
payment for the Class C Shares and Class C Rights tendered herewith in
accordance with the terms and subject to the conditions of the Offer, the
undersigned hereby sells, assigns, and transfers to, or upon the order of, the
Purchaser all right, title and interest in and to all of the Class C Shares and
Class C Rights that are being tendered hereby and any and all dividends on the
Class C Shares or any distribution (including, without limitation, the issuance
of additional Class C Shares pursuant to a stock dividend or stock split, the
issuance of other securities or the issuance of rights (other than the
separation of the Class C Rights from the Class C Shares) for the purchase of
any securities) with respect to the Class C Shares or Class C Rights (other
than the Redemption Price (as defined in the Offer to Purchase)) that is
declared or paid by the Company on or after August 30, 1994 and is payable or
distributable to stockholders of record on





                                       6
<PAGE>   7



a date prior to the transfer into the name of the Purchaser or its nominees or
transferees on the Company's stock transfer records of the Class C Shares and
Class C Rights purchased pursuant to the Offer (except that if the Class C
Rights are redeemed by the Company's Board of Directors, tendering stockholders
who are holders of record as of the applicable record date will be entitled to
receive and retain the Redemption Price) (a "Distribution"), and constitutes
and irrevocably appoints the Depositary the true and lawful agent,
attorney-in-fact and proxy of the undersigned to the full extent of the
undersigned's rights with respect to such Class C Shares and Class C Rights
(and any Distributions) with full power of substitution (such power of attorney
and proxy being deemed to be an irrevocable power coupled with an interest), to
(a) deliver Share Certificates and Rights Certificates (and any Distributions),
together with all accompanying evidences of transfer and authenticity, to or
upon the order of the Purchaser upon receipt by the Depositary, as the
undersigned's agent, of the purchase price, (b) present such Class C Shares and
Class C Rights (and any Distributions) for transfer on the books of the
Company, (c) if directed by the Purchaser, present Share Certificates (and any
Distributions), together with any required notice, for conversion on behalf of
the undersigned into shares of Class A Common Stock, par value $.01 per share
("Class A Shares"), of the Company (and any dividends or distributions ("Class
A Distributions") into which a Distribution is convertible) and then to present
the Class A Shares (and Class A Distributions) into which such Class C Shares
(and Distributions) were converted for transfer on the books of the Company,
and (d) receive all benefits and otherwise exercise all rights of beneficial
ownership of such Class C Shares and Class C Rights (and any Distributions) or
the Class A Shares (and any Class A Distributions) into which they were
converted, all in accordance with the terms of the Offer.

        The undersigned understands that if the Distribution Date (as
defined in the Offer to Purchase) has occurred and Rights Certificates have
been distributed by the Company to holders of Class C Shares prior to the time
Class C Shares are tendered herewith, in order for Class C Rights (and the
corresponding Class C Shares) to be validly tendered, Rights Certificates
representing a number of Class C Rights equal to the number of Class C Shares
being tendered herewith must be delivered to the Depositary.  If the
Distribution Date has occurred and Rights Certificates have not been
distributed prior to the time Class C Shares and Class C Rights are tendered
herewith, the undersigned agrees to deliver Rights Certificates representing a
number





                                       7
<PAGE>   8
of Class C Rights equal to the number of Class C Shares tendered herewith to
the Depositary within five business days after the date such Rights
Certificates are distributed.  The undersigned understands that if the Rights
Condition is not satisfied, the Purchaser reserves the right to require that
the Depositary receive Rights Certificates with respect to such Class C Rights
prior to accepting the related Class C Shares for payment, if the Distribution
Date occurs prior to the Expiration Date.  In that event, payment for Class C
Shares tendered and accepted for payment pursuant to the Offer will be made
only after timely receipt by the Depositary of, among other things, such Rights
Certificates.

        The undersigned hereby irrevocably appoints Charles H. Harff and
William J. Calise, Jr., and each of them, the attorneys-in-fact and proxies of
the undersigned, each with full power of substitution, to vote in such manner
as each such attorney and proxy or his substitute shall, in his sole
discretion, deem proper, and otherwise act (including pursuant to written
consent) with respect to all of the Class C Shares and Class C Rights tendered
hereby which have been accepted for payment by the Purchaser prior to the time
of such vote or action (and any Distributions) which the undersigned is
entitled to vote at any meeting of stockholders (whether annual or special and
whether or not an adjourned meeting) of the Company, or by written consent in
lieu of such meeting, or otherwise.  This power of attorney and proxy is
coupled with an interest in the Company and in the Class C Shares and Class C
Rights and is irrevocable and is granted in consideration of, and is effective
upon, the acceptance for payment of such Class C Shares and Class C Rights by
the Purchaser in accordance with the terms of the Offer.  Such acceptance for
payment shall revoke, without further action, any other power of attorney or
proxy granted by the undersigned at any time with respect to such Class C
Shares and Class C Rights (and any Distributions) and no subsequent powers of
attorney or proxies will be given (and if given will be deemed not to be
effective) with respect thereto by the undersigned.  The undersigned
understands that the Purchaser reserves the right to require that, in order for
Class C Shares and Class C Rights to be deemed validly tendered, immediately
upon the Purchaser's acceptance for payment of such Class C Shares and Class C
Rights, the Purchaser is able to exercise full voting rights with respect to
such Class C Shares, Class C Rights and other securities, including voting at
any meeting of stockholders.  In addition, this power of attorney and proxy
applies to any Class A Shares (and Class A Distributions) into which Class C
Shares (and Distributions) have been converted.

        The undersigned hereby represents and warrants that the
undersigned has full power and authority to tender, sell, assign and transfer
the Class C Shares and Class C Rights tendered hereby (and any Distributions)
and that, when the same are accepted for payment by the Purchaser, the
Purchaser will acquire good, marketable and unencumbered title thereto, free
and clear of all liens, restrictions, charges and encumbrances and the same
will not be subject to any adverse claim.  The undersigned, upon request, will
execute and deliver any additional documents deemed by the Depositary or the
Purchaser to be necessary or desirable to complete the sale, assignment and
transfer of the Class C Shares and Class C Rights tendered hereby (and any
Distributions).  In addition, the undersigned shall promptly remit and transfer
to the Depositary for the account of the Purchaser any and all other
Distributions in respect of the Class C Shares and Class C Rights tendered
hereby, accompanied by appropriate documentation of transfer and, pending such
remittance or appropriate assurance thereof, the Purchaser shall be entitled to
all rights and privileges as owner of any such Distributions, and may withhold
the entire purchase price or deduct from the purchase price of Class C Shares
and Class C Rights tendered hereby the amount or value thereof, as determined
by the Purchaser in its sole discretion.

        All authority herein conferred or herein agreed to be conferred
shall not be affected by, and shall survive, the death or incapacity of the
undersigned and any obligation of the undersigned hereunder shall be binding
upon the heirs, executors, administrators, legal representatives, successors
and assigns of the undersigned.  Except as stated in the Offer to Purchase,
this tender is irrevocable.

        The undersigned understands that tenders of Class C Shares and
Class C Rights pursuant to any one of the procedures described in Section 3 of
the Offer to Purchase and in the instructions hereto will constitute a binding
agreement between the undersigned and the Purchaser upon the terms and subject
to the conditions of the Offer.

Instructions," please issue the check for the purchase price and/or return any
Share Certificates or Rights Certificates not tendered or accepted for payment
in the name(s) of the undersigned.  Similarly, unless otherwise indicated under
"Special Delivery Instructions," please mail the check for the purchase price

payment any of such Class C Shares and Class C Rights.

capacity, such persons should so indicate when signing, and proper evidence
satisfactory to the Purchaser of their authority so to act must be submitted.

    When this Letter of Transmittal is signed by the registered owner(s) of the
Class C Shares or Class C Rights listed and transmitted hereby, no endorsements
of certificates or separate stock powers are required unless payment is to be
made to or certificates for Class C Shares or Class C Rights not tendered or
purchased are to be issued in the name of a person other than the registered
owner(s).  Signatures on such certificates or stock powers must be guaranteed
by an Eligible Institution.

    If this Letter of Transmittal is signed by a person other than the
registered owner(s) of the Class C Shares or Class C Rights listed, the

endorsed or accompanied by appropriate stock powers, in either case signed
exactly as the name or names of the registered owner(s) appear(s) on the
certificates.  Signatures on such certificates or stock powers must be
guaranteed by an Eligible Institution.

    6.  STOCK TRANSFER TAXES.  Except as set forth in this Instruction 6, the
Purchaser will pay or cause to be paid any stock transfer taxes with respect to
the transfer and sale of purchased Class C Shares to it or its order pursuant
to the Offer.  If, however, payment of the purchase price is to be made to, or
if certificates for Class C Shares not tendered or purchased are to be
registered in the name of, any person other than the registered holder, or if
tendered certificates are registered in the name of any person other than the
person(s) signing this Letter of Transmittal, the amount of any stock transfer
taxes (whether imposed on the registered holder or such person) payable on
account of the transfer to such person will be deducted from the purchase price
unless satisfactory evidence of the payment of such taxes or exemption
therefrom is submitted.

    EXCEPT AS PROVIDED IN THIS INSTRUCTION 6, IT WILL NOT BE NECESSARY FOR
TRANSFER TAX STAMPS TO BE AFFIXED TO THE CERTIFICATES LISTED IN THIS LETTER OF
TRANSMITTAL.

    7.  SPECIAL PAYMENT AND DELIVERY INSTRUCTIONS.  If a check is to be issued
in the name of and/or certificates for unpurchased Class C Shares or Class C
Rights are to be returned to a person other than the signer of this Letter of
Transmittal or if a check is to be sent and/or such certificates are to be
returned to someone other than the signer of this Letter of Transmittal or to
an address other than that shown on the front cover hereof, the appropriate
boxes on this Letter of Transmittal should be completed.  See Instruction 1.

    8.  REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.  Requests for assistance
may be directed to the Information Agent at its addresses set forth below.
Requests for additional copies of the Offer to Purchase and this Letter of
Transmittal may be directed to the Information Agent or to brokers, dealers,
commercial banks or trust companies.

    9.  31% BACKUP WITHHOLDING; SUBSTITUTE FORM W-9.  Under U.S. Federal income
tax law, a stockholder whose tendered Class C Shares are accepted for payment
is required to provide the Depositary with such stockholder's correct taxpayer
identification number ("TIN") on Substitute Form W-9 below.  If the Depositary
is not provided with the correct TIN, the Internal Revenue Service may subject
the





                                       16
<PAGE>   17



stockholder or other payee to a $50 penalty.  In addition, payments that are
made to such stockholder or other payee with respect to Class C Shares or Class
C Rights purchased pursuant to the Offer may be subject to 31% backup
withholding.

    Certain stockholders (including, among others, all corporations and certain
foreign individuals) are not subject to these backup withholding and reporting
requirements.  In order for a foreign individual to qualify as an exempt
recipient, the stockholder must submit a Form W-8, signed under penalties of
perjury, attesting to that individual's exempt status.  A Form W-8 can be
obtained from the Depositary.  See the enclosed "Guidelines for Certification
of Taxpayer Identification Number on Substitute Form W-9" for more
instructions.

    If backup withholding applies, the Depositary is required to withhold 31%
of any such payments made to the stockholder or other payee.  Backup
withholding is not an additional tax.  Rather, the tax liability of persons
subject to backup withholding will be reduced by the amount of tax withheld.
If withholding results in an overpayment of taxes, a refund may be obtained
from the Internal Revenue Service.

    The box in Part 3 of the Substitute Form W-9 may be checked if the
tendering stockholder has not been issued a TIN and has applied for a TIN or
intends to apply for a TIN in the near future.  If the box in Part 3 is
checked, the stockholder or other payee must also complete the Certificate of
Awaiting Taxpayer Identification Number below in order to avoid backup
withholding.  Notwithstanding that the box in Part 3 is checked and the
Certificate of Awaiting Taxpayer Identification Number is completed, the
Depositary will withhold 31% of all payments made prior to the time a properly
certified TIN is provided to the Depositary.

    The stockholder is required to give the Depositary the TIN (e.g., social
security number or employer identification number) of the record owner of the
Class C Shares or Class C Rights or of the last transferee appearing on the
transfers attached to, or endorsed on, the Class C Shares or Class C Rights.
If the Class C Shares or Class C Rights are in more than one name or are not in
the name of the actual owner, consult the enclosed "Guidelines for
Certification of Taxpayer Identification Number on Substitute Form W-9" for
additional guidance on which number to report.

<PAGE>   18
    10.  LOST, DESTROYED OR STOLEN CERTIFICATES.  If any certificate(s)
representing Class C Shares or Class C Rights has been lost, destroyed or
stolen, the stockholder should promptly notify the Depositary.  The stockholder
will then be instructed as to the steps that must be taken in order to replace
the certificate(s).  This Letter of Transmittal and related documents cannot be
processed until the procedures for replacing lost or destroyed certificates
have been followed.

    IMPORTANT:  THIS LETTER OF TRANSMITTAL (OR A FACSIMILE COPY HEREOF)
TOGETHER WITH CERTIFICATES AND ALL OTHER REQUIRED DOCUMENTS MUST BE RECEIVED BY
THE DEPOSITARY ON OR PRIOR TO THE EXPIRATION DATE.

                       ROCKWELL INTERNATIONAL CORPORATION

    THE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT 12:00 MIDNIGHT, NEW YORK
     CITY TIME, ON FRIDAY, NOVEMBER 18, 1994, UNLESS THE OFFER IS EXTENDED
 
                                                                October 21, 1994
To Brokers, Dealers, Commercial Banks,
  Trust Companies and Other Nominees:
 
     We have been appointed by ROK Acquisition Corporation, a Delaware
corporation (the "Purchaser"), and Rockwell International Corporation, a
Delaware corporation ("Rockwell"), to act as financial advisor and Dealer
Manager in connection with the Purchaser's offer to purchase (i) all outstanding
shares of Class A Common Stock, par value $.01 per share (the "Class A Shares"),
of Reliance Electric Company, a Delaware corporation (the "Company"), and
(unless and until the Purchaser declares that the Rights Condition (as defined
below) has been satisfied) the associated Series A preferred stock purchase
rights (the "Class A Rights") issued pursuant to the Rights Agreement dated as
of August 29, 1994 between the Company and Society National Bank, as Rights
Agent (as the same may be amended, the "Rights Agreement"), at a purchase price
of $30 per Class A Share (and associated Class A Right), net to the seller in
cash, without interest thereon, (ii) all outstanding shares of Class B Common
Stock, par value $.01 per share (the "Class B
<PAGE>   2
 
Shares"), of the Company and (unless and until the Purchaser declares that the
Rights Condition has been satisfied) the associated Series B preferred stock
purchase rights (the "Class B Rights") issued pursuant to the Rights Agreement
at a purchase price of $30 per Class B Share (and associated Class B Right), net
to the seller in cash, without interest thereon, and (iii) all outstanding
shares of Class C Common Stock, par value $.01 per share (the "Class C Shares"
and, together with the Class A Shares and the Class B Shares, the "Shares"), of
the Company and (unless and until the Purchaser declares that the Rights
Condition has been satisfied) the associated Series C preferred stock purchase
rights (the "Class C Rights" and, together with the Class A Rights and the Class
B Rights, the "Rights") issued pursuant to the Rights Agreement at a purchase
price of $81.24 per Class C Share (and associated Class C Right), net to the
seller in cash, without interest thereon, in each case, upon the terms and
subject to the conditions set forth in the Offer to Purchase, dated October 21,
1994 (the "Offer to Purchase"), and in the related Letters of Transmittal (which
together constitute the "Offer") enclosed herewith. Unless and until the
Purchaser declares that the Rights Condition is satisfied, holders of Shares
will be required to tender one associated Right for each Share tendered in order
to effect a valid tender of such Share. If the Distribution Date (as defined in
the Offer to Purchase) does not occur prior to the Expiration Date (as defined
in the Offer to Purchase), a tender of Shares will also constitute a tender of
the associated Rights. If the Distribution Date occurs and certificates
representing Rights ("Rights Certificates") are distributed by the Company to
holders of Shares prior to the time a holder's Shares are tendered pursuant to
the Offer, in order for Rights (and the corresponding Shares) to be validly
tendered, Rights Certificates representing a number (and the series) of Rights
equal to the number (and class) of Shares tendered must be delivered to the
Depositary (as defined below) or, if available in the case of Class A Rights, a
Book-Entry Confirmation (as defined in the Offer to Purchase) received by the
Depositary with respect thereto. If the Distribution Date occurs and Rights
Certificates are not distributed prior to the time Shares are tendered pursuant
to the Offer, Rights may be tendered prior to a stockholder receiving Rights
Certificates by use of the guaranteed delivery procedure described in Section 3
of the Offer to Purchase. In any case, a tender of Shares constitutes an
agreement by the tendering stockholder to deliver Rights Certificates
representing a number (and series) of Rights equal to the number (and class) of
Shares tendered pursuant to the Offer to the Depositary within five business
days after the date Rights Certificates are distributed. The Purchaser reserves
the right to require that the Depositary receive Rights Certificates, or a
Book-Entry Confirmation, if available in the case of the Class A Rights, with
respect to such Rights, prior to accepting the related Shares for payment
pursuant to the Offer, if the Distribution Date occurs prior to the Expiration
Date. Holders of Shares and Rights whose certificates for such Shares (the
"Share Certificates") and, if applicable, Rights Certificates, are not
immediately available (including, if the Distribution Date has occurred, because
Rights Certificates have not yet been distributed by the Company), or who cannot
deliver their Share Certificates or, if applicable, their Rights Certificates,
and all other required documents to the Depositary on or prior to the Expiration
Date, or, in the case of the Class A Shares, who cannot complete the procedures
for book-entry transfer on a timely basis, must tender their Shares and Rights
according to the guaranteed delivery procedures set forth in Section 3 of the
Offer to Purchase. Unless the context otherwise requires, all references to
Shares shall include the associated Rights and all references to the Rights
shall include all benefits that may inure to holders of Rights pursuant to the
Rights Agreement.
 
     Please furnish copies of the enclosed materials to those of your clients
for whose accounts you hold Shares or, if applicable, Rights registered in your
name or in the name of your nominee.
 
     The Offer is conditioned upon, among other things, (1) Shares representing
at least a majority of the total number of outstanding Class A Shares on a fully
diluted basis (assuming conversion of all outstanding Class B Shares and Class C
Shares into Class A Shares and the exercise of all outstanding options) being
validly tendered and not withdrawn prior to the expiration of the Offer, (2) the
Agreement and Plan of Merger, dated as of August 30, 1994 (the "General Signal
Merger Agreement"), between the Company and General Signal Corporation ("General
Signal") having been terminated without any payments by or penalties to the
Company (other than any applicable payments pursuant to Section 9.05(b) of the
General Signal Merger Agreement) and the Company not having entered into or
effectuated any new or amended agreements with General Signal or any other
person or entity having the effect of impairing the ability of the Purchaser to
acquire the Company or otherwise diminishing the expected economic value to the
Purchaser of the acquisition of the Company, (3) the Rights having been redeemed
by the Board of Directors of the Company
 
                                        2

or the Purchaser being satisfied, in its sole discretion, that the Rights have
been invalidated or otherwise are inapplicable to the Offer and the Proposed
Rockwell Merger (as defined in the Offer to Purchase) (the "Rights Condition")
and (4) the Purchaser being satisfied, in its sole discretion, that Section 203
of the Delaware General Corporation Law has been complied with in connection
with the Purchaser's acquisition of the Company or is invalid or otherwise
inapplicable to the Purchaser in connection with the Offer and the Proposed
Rockwell Merger. The Offer is also subject to other terms and conditions

associated Right for each Share tendered in order to effect a valid tender of
such Share. If the Distribution Date (as defined in the Offer to Purchase) does
not occur prior to the Expiration Date (as defined in the Offer to Purchase), a
tender of Shares will also constitute a tender of the associated Rights. If the
Distribution Date occurs and certificates representing Rights ("Rights
Certificates") are distributed by the Company to holders of Shares prior to the
time a holder's Shares are tendered pursuant to the Offer, in order for Rights
(and the corresponding Shares) to be validly tendered, Rights Certificates
representing a number (and the series) of Rights equal to the number (and class)

the Distribution Date occurs and Rights Certificates are not distributed prior
to the time Shares are tendered pursuant to the Offer, Rights may be tendered
prior to a stockholder receiving Rights Certificates by use of the guaranteed
delivery procedure described in Section 3 of the Offer to Purchase. In any case,
a tender of Shares constitutes an agreement by the tendering stockholder to
deliver Rights Certificates representing a number (and series) of Rights equal
to the number (and class) of Shares tendered pursuant to the Offer to the
Depositary within five business days after the date Rights Certificates are
distributed. The Purchaser reserves the right to require that the Depositary
receive Rights Certificates, or a Book-Entry Confirmation, if available in the
case of the Class A Rights, with respect to such Rights, prior to accepting the
related Shares for payment pursuant to the Offer, if the Distribution Date
occurs prior to the Expiration Date. Holders of Shares and Rights whose
certificates for such Shares (the "Share Certificates") and, if applicable,
Rights Certificates, are not immediately available (including, if the
Distribution Date has occurred, because Rights Certificates have not yet been
distributed by the Company), or who cannot deliver their Share Certificates or,
if applicable, their Rights Certificates, and all other required documents to
the Depositary on or prior to the Expiration Date, or, in the case of the Class
A Shares, who cannot complete the procedures for book-entry transfer on a timely
basis, must tender their Shares and Rights according to the guaranteed delivery
procedures set forth in Section 3 of the Offer to Purchase. Unless the context
otherwise requires, all references to Shares shall include the associated Rights
and all references to the Rights shall include all benefits that may inure to

     inapplicable to the Offer and the Proposed Rockwell Merger (as defined in
     the Offer to Purchase) (the "Rights Condition") and (4) the Purchaser being
     satisfied, in its sole discretion, that Section 203 of the Delaware General
     Corporation Law has been complied with in connection with the Purchaser's

          4. Tendering stockholders will not be obligated to pay brokerage fees
     or commissions or, except as otherwise provided in Instruction 6 of the
     Letters of Transmittal, stock transfer taxes on the purchase of Shares or
     Rights by the Purchaser pursuant to the Offer.
 
          5. The Offer and withdrawal rights will expire at 12:00 midnight, New

     associated Rights Certificates or, in the case of Class A Shares, timely
     confirmation of the book-entry transfer of such Shares and, if available,

     documents required by the appropriate Letter of Transmittal. Accordingly,
     payment may not be made to all tendering stockholders at the same time
     depending upon when certificates for or, in the case of Class A Shares,
     confirmations of book-entry transfer of such Shares (or associated Rights,
     if available) into the Depositary's account at a Book-Entry Transfer
     Facility are actually received by the Depositary.
 
     If you wish to have us tender any or all of the Shares held by us for your
account, please so instruct us by completing, executing, detaching and returning
to us the instruction form set forth on the back page of this letter. If you
authorize the tender of your Shares, all such Shares will be tendered unless
otherwise specified on the back page of this letter. An envelope to return your
instructions to us is enclosed. Your authorization to tender Shares shall be
deemed authorization to tender the associated Rights regardless of whether they
separate from the Shares. Your instructions should be forwarded to us in ample
time to permit us to submit a tender on your behalf prior to the expiration of
the Offer.
 
     The Offer is not being made to (nor will tenders be accepted from or on
behalf of) holders of Shares or Rights residing in any jurisdiction in which the
making of the Offer or the acceptance thereof would not be in compliance with
the securities, blue sky or other laws of such jurisdiction. However, the
Purchaser may, in its discretion, take such action as it may deem necessary to
make the Offer in any jurisdiction and extend the Offer to holders of Shares in
such jurisdiction.
 
     In any jurisdiction where the securities, blue sky or other laws require
the Offer to be made by a licensed broker or dealer, the Offer is being made on
behalf of the Purchaser by Dillon, Read & Co. Inc., the Dealer Manager for the
Offer, or one or more registered brokers or dealers that are licensed under the
laws of such jurisdiction.

     Unless and until the Purchaser declares that the Rights Condition is
satisfied, holders of Shares are required to tender one associated Right for
each Share tendered in order to effect a valid tender of such Share. If
certificates representing Rights ("Rights Certificates") have been distributed
by the Company to holders of Shares, such holders will be required to validly
tender Rights Certificates representing a number (and series) of Rights equal to
the number (and class) of Shares being tendered in order to effect a valid
tender of such Shares. If Rights Certificates have not been distributed by the
Company to holders of Shares, a tender of Shares will also constitute a tender
of the associated Rights and only the line with respect to "Number of Shares to
Be Tendered" should be filled in. See Section 3 of the Offer to Purchase. Unless
otherwise indicated, it will be assumed that you instruct us to tender all
Shares and Rights held by us for your account and that you instruct us to tender
all Rights associated with Shares you have instructed us to tender.

(3) CRIMINAL PENALTY FOR FALSIFYING INFORMATION.--Falsifying certifications or
affirmations may subject you to criminal penalties including fines and/or
imprisonment.

ROCKWELL ANNOUNCES $30 PER SHARE ALL-CASH TENDER OFFER FOR
ALL SHARES OF RELIANCE ELECTRIC COMPANY
IN TRANSACTION VALUED AT $1.5 BILLION


SEAL BEACH, Calif., October 20, 1994 -- Rockwell International
Corporation (NYSE: ROK) announced today that on Friday, October
21, it will commence an all-cash tender offer for all shares of
Reliance Electric Company at a price of $30 per share of Class A
common stock and an equivalent price for convertible shares.
This offer was communicated today in a letter from Donald R.
Beall, Rockwell's Chairman and Chief Executive Officer, to
H. Virgil Sherrill, Chairman of the Board, and John C. Morley,
President and Chief Executive Officer, of Reliance Electric.

         The Rockwell offer, which has a total transaction value of
approximately $1.5 billion, represents a premium of 22.4% over
yesterday's Reliance Electric closing market price of $24.50 per
Class A share, and 50.9% over the closing market price on August
29, the day before Reliance Electric's merger agreement with
General Signal Corporation was announced.

         Following is the complete text of Mr. Beall's letter to
Messrs. Sherrill and Morley:


         Mr. H. Virgil Sherrill
         Chairman of the Board
         and
         Mr. John C. Morley
         President and Chief Executive Officer
         Reliance Electric Company
         6065 Parkland Boulevard
         Cleveland, Ohio 44124

         Gentlemen:

         As you know, Rockwell and Reliance Electric over the years
         have worked together closely and cordially on a number of projects 
         and, during this time, have discussed a business combination of 
         our two companies.  As recently as this past July, Rockwell 
         expressed its interest in acquiring Reliance Electric, and we urged 
         you, John, to communicate our interest to the Reliance Electric 
         board, which you indicated you would do.  We were therefore surprised 
         and disappointed that Rockwell was not afforded an opportunity to 
         further pursue those discussions before Reliance Electric and
         General Signal Corporation announced a definitive merger agreement 
         at the end of August.

         After an intensive strategic review, including a detailed evaluation
         of publicly available information concerning Reliance Electric, we
         have concluded that the strategic and financial advantages of
         combining our two companies are too compelling to ignore.
         
         Accordingly, I am writing to inform you of our intention to    
         acquire Reliance Electric through a cash tender offer of $30 per
         share for all shares of Reliance Electric's Class A common stock
         and an equivalent price for its convertible shares.  This represents
         and exceptionally attractive opportunity for your shareowners --
         specifically, an all cash offer at a premium of 22.4% over
         yesterday's closing market price of $24.50 per Class A share
         and 50.9% over the closing market price on August 29, the day before
         Reliance Electric's merger agreement with General Signal was
         announced.

                                                                               3

          The transaction we propose also represents a particularly
          attractive opportunity to build a combined enterprise uniquely
          positioned for continued leadership in both the control and power
          segments of the industrial automation business, in North America and
          around the world.

          Combining the operations of our Allen-Bradley automation
          business and Reliance Electric will establish a global industrial
          automation enterprise with combined annual sales of about $3.5
          billion.  It will have a broad range of man-machine interface,
          sensor, control logic, mechanical transmission, motor and motor
          controller products, drive systems capabilities, and global support
          services. As such, the combined business can better capitalize on an
          important, long-term technological trend in industrial automation:
          the convergence of the control and power functions in increasingly
          intelligent automation products.

          We have enormous respect for Reliance Electric, a major
          manufacturer of industrial products and telecommunications equipment. 
          As you know, Allen-Bradley, which we acquired in 1985 as part of our
          continuing strategic program to grow the commercial side of our
          company, has established Rockwell as a leading worldwide manufacturer
          of automation control products.  Since the acquisition, Allen-Bradley
          has more than doubled its sales, and expects to report sales of more
          than $2.1 billion for fiscal 1994.

          Allen-Bradley has many strengths in control logic, man-machine
          interfaces and sensors.  Reliance Electric has complementary
          strengths in motors and drives. Supported by Rockwell's financial
          resources and advanced technology, the combined entity will be a
          formidable U.S.-based global industrial automation enterprise,
          well-positioned to compete with its international competitors.

          Our offer is not subject to any financing contingencies.  In
          addition, we are advised by our legal counsel that there are no
          significant antitrust or other issues associated with a combination
          of our two companies.

          While Rockwell is and will continue to be actively engaged in
          various telecommunications markets, we have determined to sell
          Reliance Electric's telecommunications operations because they do not
          fit into Rockwell's strategic plans.

          We are convinced that a combination of Allen-Bradley and
          Reliance Electric makes compelling strategic and financial sense for
          both our companies and our respective constituents.  I stand ready to
          meet with your board to present our plans.

          Sincerely,

          /signed/

                          a wholly-owned subsidiary of
                       Rockwell International Corporation

         ROK Acquisition Corporation (the "Purchaser"), a Delaware corporation
and a wholly-owned subsidiary of Rockwell International Corporation, a Delaware
corporation ("Rockwell"), hereby offers to purchase (i) all outstanding shares
of Class A Common Stock, par value $.01 per share (the "Class A Shares"), of
Reliance Electric Company, a Delaware corporation (the "Company"), and (unless 
and until the Purchaser declares that the Rights Condition (as defined below) 
has been satisfied) the associated Series A preferred stock purchase rights 
(the "Class A Rights") issued pursuant to the Rights Agreement, dated as of 
August 29, 1994, between the Company and Society National Bank, as Rights Agent 
(as the
<PAGE>   2
same may be amended, the "Rights Agreement"), at a purchase price of $30 per
Class A Share (and associated Class A Right), net to the seller in cash,
without interest thereon, (ii) all outstanding shares of Class B Common Stock,
par value $.01 per share (the "Class B Shares"), of the Company and (unless and
until the Purchaser declares that the Rights Condition has been satisfied) the
associated Series B preferred stock purchase rights (the "Class B Rights")
issued pursuant to the Rights Agreement at a purchase price of $30 per Class
B Share (and associated Class B Right), net to the seller in cash, without
interest thereon and (iii) all outstanding shares of Class C Common Stock, par
value $.01 per share (the "Class C Shares" and, together with the Class A
Shares and the Class B Shares, the "Shares"), of the Company and (unless and
until the Purchaser declares that the Rights Condition has been satisfied) the
associated Series C preferred stock purchase rights (the "Class C Rights" and,
together with the Class A Rights and the Class B Rights, the "Rights") issued
pursuant to the Rights Agreement at a purchase price of $81.24 per Class C Share
(and associated Class C Right), net to the seller in cash, without interest
thereon, in each case upon the terms and subject to the conditions set forth in
the Offer to Purchase, dated October 21, 1994 (the "Offer to Purchase"), and in
the related Letters of Transmittal (which together constitute the
"Offer").  Unless the context otherwise requires, all references to Shares
shall include the associated Rights and all references to the Rights shall
include all benefits that may inure to holders of the Rights pursuant to the
Rights Agreement.

              THE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT 12:00
          MIDNIGHT, NEW YORK CITY TIME, ON FRIDAY, NOVEMBER 18, 1994,
                          UNLESS THE OFFER IS EXTENDED.


         The Purchaser reserves the right to amend the Offer (including amending
the purchase price) upon entry into a merger agreement with the Company or
otherwise or to negotiate a merger agreement with the Company not involving a
tender offer.  The Purchaser and Rockwell also reserve the right to solicit the
votes of the stockholders of the Company at any annual or special meeting of
such stockholders.

         The Offer is conditioned upon, among other things, (1) Shares
representing at least a majority of the total number of outstanding shares of
Class A Common Stock of the Company





                                       2
<PAGE>   3
on a fully diluted basis (assuming conversion of all outstanding Class
B  Shares and Class C Shares into Class A Shares and the exercise of all
outstanding options) being validly tendered and not withdrawn prior to the
expiration of the Offer, (2) the Agreement and Plan of Merger, dated as of
August 30, 1994 (the "General Signal Merger Agreement"), between the Company
and General Signal Corporation ("General Signal") having been terminated 
without any payments by or penalties to the Company (other than any applicable
payments pursuant to Section 9.05(b) of the General Signal Merger Agreement)
and the Company not having entered into or effectuated any new or amended
agreements with General Signal or any other person or entity having the effect
of impairing the ability of the Purchaser to acquire the Company or otherwise
diminishing the expected economic value to the Purchaser of the acquisition of
the Company, (3) the Rights having been redeemed by the Board of Directors of
the Company or the Purchaser being satisfied, in its sole discretion, that the 
Rights have been invalidated or otherwise are inapplicable to the Offer and 
the Proposed Rockwell Merger (as defined below) (the "Rights Condition") and 
(4) the Purchaser being satisfied, in its sole discretion, that Section 203 of 
the Delaware General Corporation Law has been complied with in connection with 
the Purchaser's acquisition of the Company or is invalid or otherwise 
inapplicable to the Purchaser in connection with the Offer and the Proposed 
Rockwell Merger.  The Offer is also subject to other terms and conditions 
contained in the Offer to Purchase.  See the Introduction and Sections 1, 14 
and 15 of the Offer to Purchase.

         The Offer is not conditioned on obtaining financing.

         The purpose of the Offer and the Proposed Rockwell Merger is to
acquire control of, and the entire equity interest in, the Company.  The
Purchaser currently intends, as soon as practicable following consummation of
the Offer, to seek to have the Company consummate a merger or similar business
combination with the Purchaser (the "Proposed Rockwell Merger") pursuant to
which each then outstanding Share (other than Shares owned by Rockwell or any
of its wholly-owned subsidiaries, Shares held in the treasury of the Company
and Shares held by stockholders who perfect appraisal rights under the Delaware
General Corporation Law) would be converted into the right to receive cash in
the same amount as received per applicable Share in the Offer, and the Company
would become a wholly-owned subsidiary of Rockwell.

         If the Distribution Date (as defined in the Offer to Purchase) does
not occur prior to the Expiration Date (as defined below), a tender of Shares
will also constitute a tender of the associated Rights.  If the Purchaser
declares that the Rights Condition is satisfied, the Purchaser will





                                       3
<PAGE>   4
not require delivery of Rights.  Unless and until the Purchaser
declares that the Rights Condition is satisfied, holders of Shares will be
required to tender one associated Right for each Share tendered in order to
effect a valid tender of such Share.  If the Distribution Date occurs and
certificates representing Rights ("Rights Certificates") are distributed by the
Company to holders of Shares prior to the time a holder's Shares are tendered
pursuant to the Offer, in order for Rights (and the corresponding Shares) to be
validly tendered, Rights Certificates representing a number (and the series) of
Rights equal to the number (and class) of Shares tendered must be delivered to
First Chicago Trust Company of New York (the "Depositary") or, if available in
the case of Class A Rights, a Book-Entry Confirmation (as defined below)
received by the Depositary with respect thereto.  If the Distribution Date
occurs and Rights Certificates are not distributed prior to the time Shares are
tendered pursuant to the Offer, Rights may be tendered prior to a stockholder
receiving Rights Certificates by use of the guaranteed delivery procedure
described in Section 3 of the Offer to Purchase.  In any case, a tender of
Shares constitutes an agreement by the tendering stockholder to deliver Rights
Certificates representing a number (and the series) of Rights equal to the
number (and class) of Shares tendered pursuant to the Offer to the Depositary
within five business days after the date Rights Certificates are distributed.
The Purchaser reserves the right to require that the Depositary receive Rights
Certificates, or a Book-Entry Confirmation, if available in the case of Class A
Rights, with respect to such Rights, prior to accepting the related Shares for
payment pursuant to the Offer if the Distribution Date occurs prior to the
Expiration Date.

         For purposes of the Offer, the Purchaser will be deemed to have
accepted for payment, and thereby purchased, Shares validly tendered and not
withdrawn as, if and when the Purchaser gives oral or written notice to the
Depositary of the Purchaser's acceptance of such Shares for payment pursuant to
the Offer.  In all cases, upon the terms and subject to the conditions of the
Offer, payment for Shares purchased pursuant to the Offer will be made by
deposit of the purchase price therefor with the Depositary, which will act as
agent for tendering stockholders for the purpose of receiving payment from the
Purchaser and transmitting payment to validly tendering stockholders.  Under no
circumstances will interest on the purchase price for Shares be paid by the
Purchaser.  In all cases, payment for Shares purchased pursuant to the Offer
will be made only after timely receipt by the Depositary of (i) certificates
representing Shares (the "Share Certificates") for such Shares and, if
applicable, Rights Certificates for the associated Rights,





                                       4
<PAGE>   5
or, in the case of Class A Shares, timely confirmation (a "Book-Entry
Confirmation") of the book-entry transfer of such Class A Shares and, if
applicable, Class A Rights into the Depositary's account at The Depository
Trust Company, Midwest Securities Trust Company or Philadelphia Depository
Trust Company (collectively, the "Book-Entry Transfer Facilities") pursuant to
the procedures set forth in Section 3 of the Offer to Purchase, (ii) the
appropriate Letter of Transmittal (or a facsimile thereof), properly completed
and duly executed, with any required signature guarantees, or, in the case of
Class A Shares, an Agent's Message (as defined in the Offer to Purchase) in
connection with a book-entry transfer of Class A Shares and, if applicable,
Class A Rights and (iii) any other documents required by the appropriate Letter
of Transmittal.  A Class A Letter of Transmittal should be used to tender Class
A Shares, a Class B Letter of Transmittal should be used to tender Class B
Shares and a Class C Letter of Transmittal should be used to tender Class C
Shares.

         If, for any reason whatsoever, acceptance for payment of any Shares
and Rights tendered pursuant to the Offer is delayed, or the Purchaser is
unable to accept for payment or pay for Shares and Rights tendered pursuant to
the Offer, then, without prejudice to the Purchaser's rights set forth in the
Offer to Purchase, the Depositary may, nevertheless, on behalf of the
Purchaser, retain tendered Shares and Rights and such Shares and Rights may not
be withdrawn except to the extent that the tendering stockholder is entitled to
and duly exercises withdrawal rights as described in Section 4 of the Offer to
Purchase.  Any such delay will be by an extension of the Offer to the extent
required by law.

         If certain events occur, the Purchaser will not be obligated to accept
for payment or pay for any Shares tendered pursuant to the Offer.  If any
tendered Shares are not purchased pursuant to the Offer for any reason, or if
Share Certificates are submitted representing more Shares than are tendered,
Share Certificates representing unpurchased or untendered Shares will be
returned, without expense to the tendering stockholder (or, in the case of
Class A Shares delivered by book-entry transfer into the Depositary's account
at a Book-Entry Transfer Facility pursuant to the procedures set forth in
Section 3 of the Offer to Purchase, such Shares will be credited to an account
maintained within such Book-Entry Transfer Facility), as promptly as
practicable following the expiration, termination or withdrawal of the Offer.
In the event separate Rights Certificates are issued, similar action will be
taken with respect to unpurchased and untendered Rights.





                                       5
<PAGE>   6
         The Purchaser expressly reserves the right, in its sole discretion, at
any time and from time to time, to extend the period during which the Offer is
open for any reason, including the occurrence of any event specified in Section
14 of the Offer to Purchase, by giving oral or written notice of such extension
to the Depositary.  Subject to the applicable regulations of the Securities and
Exchange Commission, the Purchaser also expressly reserves the right, in its
sole discretion, at any time or from time to time, to (i) delay acceptance for
payment of or, regardless of whether such Shares were theretofore accepted for
payment, payment for any Shares pending receipt of any regulatory or
governmental approvals specified in Section 15 of the Offer to Purchase, (ii)
terminate the Offer (whether or not any Shares have theretofore been accepted
for payment) if any condition referred to in Section 14 of the Offer to
Purchase has not been satisfied or upon the occurrence of any event specified
in Section 14 and (iii) waive any condition or otherwise amend the Offer in any
respect, in each case, by giving oral or written notice of such delay,  
termination, waiver or amendment to the Depositary and, other than in the case
of any such waiver, by making a public announcement thereof.  Any such
extension, delay, termination or amendment will be followed as promptly as
practicable by public announcement thereof, and such announcement in the case
of an extension will be made no later than 9:00 a.m., New York City time, on
the next business day after the previously scheduled Expiration Date.

         Except as otherwise provided in Section 4 of the Offer to Purchase,
tenders of Shares and Rights made pursuant to the Offer are irrevocable. Shares
and Rights tendered pursuant to the Offer may be withdrawn at any time  on or
prior to the Expiration Date and, unless theretofore accepted for payment as
provided in the Offer to Purchase, may also be withdrawn at any time after
December 19, 1994 (or such later date as may apply in case the Offer is
extended).  The term "Expiration Date" means 12:00 midnight, New York City
time, on Friday, November 18, 1994, unless and until the Purchaser, in its sole
discretion, shall have extended the period of time for which the Offer is open,
in which event the term "Expiration Date" shall mean the time and date at which
the Offer, as so extended by the Purchaser, shall expire.  A withdrawal of
Shares will also constitute a withdrawal of the associated Rights.  Rights may
not be withdrawn unless the associated Shares are also withdrawn.  In order for
a withdrawal to be effective, a written or facsimile transmission notice of
withdrawal must be timely received by the Depositary at one of its addresses
set forth on the back cover of the Offer to Purchase.  Any such notice of
withdrawal must specify the name of the person who tendered the Shares and
Rights to be withdrawn, the number of Shares and Rights to be withdrawn,





                                       6
<PAGE>   7
and (if Share Certificates and Rights Certificates have been tendered) the name
of the registered holder of the Shares and Rights as set forth in the Share
Certificate and Rights Certificate, if different from that of the person who
tendered such Shares and Rights.  If Share Certificates and Rights Certificates
have been delivered or otherwise identified to the Depositary, then prior to
the physical release of such certificates, the tendering stockholder must
submit the serial numbers shown on the particular certificates evidencing the
Shares and Rights to be withdrawn and the signature on the notice of withdrawal
must be guaranteed by a firm that is a bank, broker, dealer, credit union,
savings association or other entity which is a member in good standing of the
Securities Transfer Agents Medallion Program (an "Eligible Institution"), 
except in the case of Shares and Rights tendered for the account of an 
Eligible Institution.  If Class A Shares and Class A Rights have been tendered
pursuant to the procedures for book-entry transfer set forth in Section 3 of 
the Offer to Purchase, the notice of withdrawal must specify the name and 
number of the account at the appropriate Book-Entry Transfer Facility to be 
credited with the withdrawn Class A Shares and Class A Rights, in which case a
notice of withdrawal will be effective if delivered to the Depositary by
any method of delivery described in this paragraph.  All questions as to the
form and validity (including time of receipt) of notices of withdrawal will be
determined by the Purchaser, in its sole discretion, whose determination shall
be final and binding.  Any Shares and Rights properly withdrawn will be deemed
not validly tendered for purposes of the Offer, but may be retendered at any
subsequent time prior to the Expiration Date by following any of the procedures
described in Section 3 of the Offer to Purchase.

         The information required to be disclosed pursuant to Rule
14d-6(e)(1)(vii) of the General Rules and Regulations under the Securities 
Exchange Act of 1934, as amended (the "Exchange Act"), is contained in the
Offer to Purchase and is incorporated herein by reference.

         A request is being made to the Company pursuant to Rule 14d-5 under the
Exchange Act for the use of the Company's stockholder list, its list of holders
of Rights and security position listings for the purpose of disseminating the
Offer to holders of Shares.  Upon compliance by the Company with such request,
the Offer to Purchase and the related Letters of Transmittal and, if required,
other relevant materials will be mailed to record holders of Shares and Rights
and will be furnished to brokers, dealers, commercial banks, trust companies
and similar persons whose names, or the names of whose nominees, appear on the
stockholder list and list of holders of Rights, if applicable, or who are
listed as participants in a clearing

agency's security position listing for subsequent transmittal to beneficial
owners of Shares and Rights.
