To: All Holders of Shares of Common Stock of E-Systems, Inc.
 
                                  INTRODUCTION
 
  RTN Acquisition Corporation (the "Purchaser"), a Delaware corporation and a
wholly-owned subsidiary of Raytheon Company, a Delaware corporation ("Parent"),
hereby offers to purchase all outstanding shares of Common Stock, par value
$1.00 per share (the "Shares"), of E-Systems, Inc., a Delaware corporation (the
"Company"), and the associated Preferred Stock Purchase Rights (the "Rights")
issued pursuant to the Rights Agreement, dated as of October 7, 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 $64.00 per Share (and
associated Right), net to the seller in cash, without interest thereon, upon
the terms and subject to the conditions set forth in this Offer to Purchase and
in the related Letter 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, including the right to receive any payment due upon redemption of
the Rights.
 
  Tendering stockholders will not be obligated to pay brokerage fees or
commissions or, except as set forth in Instruction 6 of the Letter of
Transmittal, stock transfer taxes on the purchase of Shares 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
Letter 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 Bear, Stearns & Co. Inc., as Dealer Manager (the "Dealer
Manager"), The First National Bank of Boston, as Depositary (the "Depositary"),
and D.F. King & Co., Inc., as Information Agent (the "Information Agent"),
incurred in connection with the Offer. See Section 16.
 
  THE BOARD OF DIRECTORS OF THE COMPANY UNANIMOUSLY HAS DETERMINED THAT THE
CONSIDERATION TO BE PAID FOR EACH SHARE IN THE OFFER AND THE MERGER IS FAIR TO
THE STOCKHOLDERS OF THE COMPANY AND THAT THE OFFER AND THE MERGER ARE OTHERWISE
IN THE BEST INTERESTS OF THE COMPANY AND ITS STOCKHOLDERS AND RECOMMENDS THAT
STOCKHOLDERS ACCEPT THE OFFER AND TENDER THEIR SHARES.
 
  The Offer is conditioned upon, among other things, at least a majority of the
total number of outstanding Shares (assuming exercise of all outstanding stock
options) being validly tendered and not withdrawn prior to the Expiration Date
(as defined in Section 1) (the "Minimum Condition"). The Purchaser reserves the
right (subject to the applicable rules and regulations of the Securities and
Exchange Commission (the "Commission") and the prior written consent of the
Company), which it presently has no intention of exercising, to waive or reduce
the Minimum Condition and to elect to purchase, pursuant to the Offer, a
smaller number of Shares. The Offer is also subject to certain other terms and
conditions. See Sections 1, 14, and 15 below.
 
  The Offer is being made pursuant to the Agreement and Plan of Merger, dated
as of April 2, 1995 (the "Merger Agreement"), among the Company, the Purchaser
and Parent pursuant to which, following the consummation of the Offer and the
satisfaction or waiver of certain conditions, the Purchaser will be merged with
and into the Company (the "Merger"), with the Company continuing as the
surviving corporation (the "Surviving Corporation"). In the Merger, each
outstanding Share (other than Shares held by Parent, the Purchaser or any
subsidiary of Parent or the Purchaser or in the treasury of the Company, which
Shares, by virtue of the Merger and without any action on the part of the
holder thereof, shall be cancelled with no payment being made with respect
thereto, and other than Shares, if any, held by stockholders who perfect their
appraisal rights under Delaware law ("Dissenting Shares")) will, by virtue of
the Merger and without
<PAGE>
 
any action by the holder thereof, be converted into the right to receive
$64.00 net to its holder in cash, or any higher price paid per Share in the
Offer (the "Merger Consideration"), payable to the holder thereof, without
interest thereon, upon the surrender of the certificate formerly representing
such Share. The Merger Agreement is more fully described in Section 11 below.
Certain federal income tax consequences of the sale of Shares pursuant to the
Offer and the Merger, as the case may be, are described in Section 5 below.
 
  Each of CS First Boston Corporation ("CS First Boston") and Morgan Stanley &
Co. Incorporated ("Morgan Stanley"), the Company's financial advisors, has
delivered to the Board of Directors of the Company a written opinion to the
effect that, as of the date of the Merger Agreement, the per Share
consideration to be received by the Stockholders of the Company pursuant to
the Offer is fair to the stockholders of the Company from a financial point of
view.
 
  A copy of each such opinion is included with the Company's
Solicitation/Recommendation Statement on Schedule 14D-9 (the "Schedule 14D-
9"), which is being mailed to stockholders concurrently herewith, and
stockholders are urged to read the opinion in its entirety for a description
of the assumptions made, matters considered and limitations of the review
undertaken by each of CS First Boston and Morgan Stanley.
 
  The Company's Certificate of Incorporation requires the affirmative vote of
holders of 80% of the outstanding Shares to approve the Merger. As a result,
even if the Minimum Condition and the other conditions to the Offer are
satisfied and the Offer is consummated, it is possible that the Purchaser may
not own a sufficient number of Shares to ensure that the Merger will be
approved by the Company's stockholders. See Section 11.
 
  The Company has advised the Purchaser that, to the knowledge of the Company,
all of its executive officers and directors intend to tender all Shares which
are held of record or beneficially owned by such persons pursuant to the Offer
(other than Shares issuable upon exercise of stock options and Shares, if any,
which if tendered would cause such persons to incur liability under section 16
of the Exchange Act).
 
  The Company has informed the Purchaser that, as of March 30, 1995, there
were 34,173,453 Shares issued and outstanding and 2,391,703 Shares reserved
for issuance upon the exercise of outstanding stock options.
 
  THE OFFER IS CONDITIONED UPON THE FULFILLMENT OF CERTAIN CONDITIONS
DESCRIBED IN SECTION 14 BELOW. THE OFFER WILL EXPIRE AT 12:00 MIDNIGHT, NEW
YORK CITY TIME, ON FRIDAY, APRIL 28, 1995, UNLESS EXTENDED.
 
  THIS OFFER TO PURCHASE AND THE RELATED LETTER OF TRANSMITTAL CONTAIN
IMPORTANT INFORMATION WHICH SHOULD BE READ CAREFULLY BEFORE ANY DECISION IS
MADE WITH RESPECT TO THE 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. The term
"Expiration Date" means 12:00 midnight, New York City time, on Friday, April
28, 1995, 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.
 
  Upon the terms and subject to the conditions of the Offer, the Purchaser
will accept for payment and purchase, as soon as permitted under the terms of
the Offer, all Shares validly tendered and not withdrawn prior to the
expiration of the Offer. If at the Expiration Date, the conditions to the
Offer described in Section 14 hereof shall not have been satisfied or earlier
waived but, in the reasonable belief of Parent, may be satisfied
 
                                       2
<PAGE>
 
prior to September 30, 1995, then, subject to the provisions of the Merger
Agreement, the Purchaser will extend the Expiration Date for an additional
period or periods of time by giving oral or written notice of such extension to
the Depositary. Any individual extension of the Offer shall be for a period of
no more than 15 business days. 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 Commission and the terms of the
Merger Agreement, 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) except as set forth
in the Merger Agreement, 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 Securities Exchange Act of 1934,
as amended (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.
 
  In the Merger Agreement, the Purchaser has agreed that, without the prior
written consent of the Company, it will not (i) decrease the price per Share or
change the form of consideration payable in the Offer, (ii) decrease the number
of Shares sought, (iii) amend or waive satisfaction of the Minimum Condition or
(iv) impose additional conditions to the Offer or amend any other term of the
Offer in any manner adverse to the holders of Shares.
 
  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), 14d-6(d) and 14e-1 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, 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, 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
 
                                       3
<PAGE>
 
expiration of such period of ten business days. 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.
 
  As of the date of this Offer to Purchase, the Rights are evidenced by the
certificates representing Shares and do not trade separately. Accordingly, by
tendering a certificate representing Shares, a stockholder is automatically
tendering a similar number of associated Rights. If, however, pursuant to the
Rights Agreement or for any other reason, the Rights detach and separate
certificates representing rights ("Rights Certificates") are issued,
stockholders will be required to tender one Right for each Share tendered in
order to effect a valid tender of such Share.
 
  THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS, THE SATISFACTION OF THE
MINIMUM CONDITION.
 
  Consummation of the Offer is also conditioned upon expiration or termination
of all waiting periods imposed by the Hart-Scott-Rodino Antitrust Improvements
Act of 1976, as amended, and the regulations thereunder (the "HSR Act"), and
the other conditions set forth in Section 14 below. The Purchaser reserves the
right (but shall not be obligated), in accordance with applicable rules and
regulations of the Commission and with the Merger Agreement, 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 the exercise of its
good faith judgment, 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 and the Merger Agreement;
(ii) waive all of the unsatisfied conditions (other than the Minimum Condition)
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.
 
  In the Merger Agreement, the Purchaser has agreed that, upon the terms and
subject to the conditions to the Offer, the Purchaser will accept for payment,
all Shares validly tendered and not withdrawn prior to the expiration of the
Offer as soon as it is permitted under the terms of the Offer.
 
  In addition, the Purchaser has agreed that it will not, without the prior
written consent of the Company, (i) decrease the price per Share or change the
form of consideration payable in the Offer, (ii) decrease the number of Shares
sought, (iii) amend or waive satisfaction of the Minimum Condition or (iv)
impose additional conditions to the Offer or amend any other term of the Offer
in any manner adverse to the holders of Shares.
 
  The Company has provided the Purchaser with the Company's stockholder lists
and security position listings for the purpose of disseminating the Offer to
holders of Shares. This Offer to Purchase, the related Letter of Transmittal
and other relevant materials will be mailed by the Purchaser to record holders
of Shares and will be furnished by the Purchaser to brokers, dealers,
commercial banks, trust companies and similar persons whose names, or the names
of whose nominees, appear on the securityholder lists or, if applicable, who
are listed as participants in a clearing agency's security position listing,
for subsequent transmittal to beneficial owners of Shares.
 
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. See Section 14. In addition, subject to
applicable rules of the Commission, the Purchaser expressly reserves the right
to delay acceptance for payment of, or payment for, Shares pending receipt of
any regulatory or governmental approvals specified in Section 15.
 
                                       4
<PAGE>
 
  For information with respect to approvals required to be obtained prior to
the consummation of the Offer, including under the HSR Act and other laws and
regulations, 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) certificates representing
such Shares ("Share Certificates") or timely confirmation (a "Book-Entry
Confirmation") of the book-entry transfer of such Shares 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 an Agent's Message
(as defined below) in connection with a book-entry transfer; and (iii) any
other documents required by the 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 Shares which are the subject of such Book-Entry
Confirmation that such participant has received and agrees to be bound by the
terms of the 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 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.
 
  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, subject to the provisions of the Merger
Agreement, 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 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.
 
  Valid Tender of Shares. Except as set forth below, in order for Shares to be
validly tendered pursuant to the Offer, the Letter of Transmittal (or a
facsimile thereof), properly completed and duly executed, together
 
                                       5
<PAGE>
 
with any required signature guarantees or an Agent's Message in connection with
a book-entry delivery of Shares and any other documents required by the 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 representing tendered Shares must be
received by the Depositary or 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.
 
  THE METHOD OF DELIVERY OF SHARE CERTIFICATES, RIGHTS CERTIFICATES (IF
APPLICABLE), THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED DOCUMENTS IS AT
THE OPTION AND SOLE RISK OF THE TENDERING STOCKHOLDER, AND 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.
 
  Book-Entry Transfer. The Depositary will make a request to establish accounts
with respect to the Shares at each of the Book-Entry Transfer Facilities for
purposes of the Offer within two business days after the date of this 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 Shares by causing
such Book-Entry Transfer Facility to transfer such 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
Shares may be effected through book-entry transfer into the Depositary's
account at a Book-Entry Transfer Facility, the 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.
 
  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 tendered thereby are tendered (i) by a registered holder of
Shares who has not completed either the box labeled "Special Payment
Instructions" or the box labeled "Special Delivery Instructions" on the Letter
of Transmittal or (ii) for the account of an Eligible Institution. See
Instruction 1 of the Letter of Transmittal.
 
  If the Share 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 for unpurchased Shares 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 Letter of Transmittal. See Instructions 1 and 5
of the Letter of Transmittal.
 
  If the Share Certificates are forwarded separately to the Depositary, a
properly completed and duly executed Letter of Transmittal (or facsimile
thereof) must accompany each such delivery.
 
  Guaranteed Delivery. If a stockholder desires to tender Shares pursuant to
the Offer and such stockholder's Share Certificates are not immediately
available or time will not permit all required documents
 
                                       6
<PAGE>
 
to reach the Depositary on or prior to the Expiration Date or the procedures
for book-entry transfer cannot be completed on a timely basis, such Shares or
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 (or a Book-Entry Confirmation) representing
  all tendered Shares, in proper form for transfer together with a properly
  completed and duly executed Letter of Transmittal (or facsimile thereof),
  with any required signature guarantees (or, in the case of a book-entry
  transfer, an Agent's Message) and any other documents required by the
  Letter of Transmittal are received by the Depositary within five New York
  Stock Exchange, Inc. ("NYSE") trading days after the date of execution of
  such Notice of Guaranteed Delivery.
 
  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 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, of Book-Entry
Confirmation with respect to, such Shares, a properly completed and duly
executed Letter of Transmittal (or facsimile thereof), together with any
required signature guarantees (or, in the case of a book-entry transfer, 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 are
received by the Depositary or Book-Entry Confirmations of such Shares are
received into the Depositary's account at a Book-Entry Transfer Facility.
 
  Backup Federal Income Tax Withholding. Under the backup federal income tax
withholding 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 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
Letter of Transmittal. See Instruction 9 of the Letter of Transmittal.
 
  Appointment as Proxy. By executing the Letter of Transmittal, a tendering
stockholder irrevocably appoints designees of the Purchaser, and each of them,
as such stockholder's agents, attorneys-in-fact and proxies, with full power of
substitution, in the manner set forth in the Letter of Transmittal, to the full
extent of such stockholder's rights with respect to the Shares tendered by such
stockholder and accepted for payment by the Purchaser and with respect to any
and all other Shares and other securities or rights issued or issuable in
respect of such Shares on or after the date of this Offer to Purchase, other
than regular cash dividends at a rate not exceeding $.375 per Share per
quarter, payable on the Company's customary dividend payment dates. All such
powers of attorney and proxies shall be considered irrevocable and coupled with
an interest in the tendered Shares. Such appointment will be effective upon the
acceptance for payment of such Shares 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 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 such other
securities and rights for which such appointment is
 
                                       7
<PAGE>
 
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 to be deemed validly tendered, immediately upon the
acceptance for payment of such Shares, the Purchaser or its designee must be
able to exercise full voting rights with respect to such Shares 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 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 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 will
be final and binding. No tender of Shares 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 Parent, 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.
 
  The Purchaser's acceptance for payment of Shares 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 made
pursuant to the Offer are irrevocable. Shares 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 June 1, 1995 (or such later date as may apply in case the Offer
is extended).
 
  If, for any reason whatsoever, acceptance for payment of any Shares tendered
pursuant to the Offer is delayed, or the Purchaser is unable to accept for
payment or pay for Shares 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 such
Shares 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 to be withdrawn, the number of Shares to be withdrawn, and (if Share
Certificates have been tendered) the name of the registered holder of the
Shares as set forth in the Share Certificate, if different from that of the
person who tendered such Shares. If Share 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 to be withdrawn and
the signature on the notice of withdrawal must be guaranteed by an Eligible
Institution, except in the case of Shares tendered for the account of an
Eligible Institution. If Shares 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 Shares, in which case a
notice
 
                                       8
<PAGE>
 
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 may not be rescinded. Any Shares properly withdrawn will be deemed not
validly tendered for purposes of the Offer, but may be tendered 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 Parent, 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 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, 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. STOCKHOLDERS ARE URGED TO CONSULT THEIR TAX ADVISORS WITH
RESPECT TO THE SPECIFIC TAX CONSEQUENCES TO THEM OF THE OFFER AND MERGER,
INCLUDING FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES.

6. PRICE RANGE OF THE SHARES; DIVIDENDS.
 
  According to the Company's Annual Report on Form 10-K for the year ended
December 31, 1994 (the "Form 10-K"), the Shares are listed and traded on the
NYSE under the symbol "ESY." The following table sets forth, for the periods
indicated, the reported high and low sale prices for the Shares on the NYSE
Composite Tape and the amount of cash dividends paid per Share, as reported in
the Form 10-K with respect to periods occurring in 1993 and 1994, and as
reported thereafter by published financial sources, with respect to periods
occurring in 1995.

  On March 31, 1995, the last full day of trading prior to the announcement of
the execution of the Merger Agreement and commencement of the Offer, according
to published sources, the reported closing price on the NYSE Composite Tape for
the Shares was $45 3/8 per Share.
 
  STOCKHOLDERS ARE URGED TO OBTAIN CURRENT MARKET QUOTATIONS FOR THE SHARES.
 
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
Shares pursuant to the Offer will reduce the number of Shares that might
otherwise trade publicly and could adversely affect the liquidity and market
value of the remaining Shares held by the public. The purchase of Shares
pursuant to the Offer can also be expected to reduce the number of holders of
Shares. The Purchaser cannot predict whether the reduction in the number of
Shares that might otherwise trade publicly would have an adverse or beneficial
effect on the market price for or marketability of the 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 Shares if, among other things, the number of
record holders of at least 100 Shares should fall below 1,200, the number of
publicly held 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 Shares (exclusive of NYSE Excluded Holdings) should fall below
$5,000,000.
 
  Depending upon the number of Shares acquired pursuant to the Offer, the
Shares may no longer meet the requirements for continued listing on the NYSE.
If as a result of the purchase of Shares pursuant to the Offer, Shares no
longer meet the requirements of the NYSE for continued listing and the listing
of the Shares is discontinued, the market for the Shares could be adversely
affected.
 
  In the event that the Shares were no longer listed or traded on the NYSE, it
is possible that the 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 Shares remaining at such
 
                                       10
<PAGE>
 
time, the interest in maintaining a market in the Shares on the part of
securities firms, the possible termination of registration of the Shares under
the Exchange Act as described below and other factors.
 
  Exchange Act Registration. The Shares are currently registered under the
Exchange Act. The purchase of the Shares pursuant to the Offer may result in
the Shares becoming eligible for deregistration under the Exchange Act.
Registration of the Shares may be terminated upon application by the Company
to the Commission if the Shares are not listed on a "national securities
exchange" and there are fewer than 300 record holders of Shares. Termination
of registration of the 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
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 Shares under the Exchange
Act were terminated, the Shares would no longer be "margin securities" or
eligible for stock exchange listing or NASDAQ reporting. The Purchaser
believes that the purchase of the Shares pursuant to the Offer may result in
the 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 Shares as soon as possible
after successful completion of the Offer if the Shares are then eligible for
such termination.
 
  If registration of the Shares is not terminated prior to the Merger, then
the Shares will be delisted from the NYSE and the registration of the Shares
under the Exchange Act will be terminated following the consummation of the
Merger.
 
  Margin Regulations. The 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 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 Shares and
the number and market value of publicly held Shares, following the purchase of
Shares pursuant to the Offer, the 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 Shares under the Exchange Act
were terminated, the Shares would no longer constitute "margin securities."

  Although neither Parent nor Purchaser has any knowledge that any such
information is untrue, neither Parent nor the Purchaser takes any
responsibility for the accuracy or completeness of information contained in
this Offer to Purchase with respect to the Company or any of its subsidiaries
or affiliates or for any failure by the Company to disclose events which may
have occurred or may affect the significance or accuracy of any such
information.
 
  In the course of the discussions between representatives of Parent and the
Company (see Section 10) certain projections of future operating performance
were furnished to Parent's representatives. These projections were not prepared
with a view to public disclosure or compliance with published guidelines of the
Commission or the guidelines established by the American Institute of Certified
Public Accountants regarding projections, and are included in this Offer to
Purchase only because they were provided to Parent. Neither Parent, the
Purchaser nor the Company, nor either of their financial advisors nor the
Dealer Manager assumes any responsibility for the accuracy of these
projections. While presented with numerical specificity, these projections are
based upon a variety of assumptions relating to the businesses of the Company
which may not be realized and are subject to significant uncertainties and
contingencies, many of which are beyond the control of the Company. There can
be no assurance that the projections will be realized, and actual results may
vary materially from those shown.
 
  Set forth below is a summary of the projections. The projections should be

10. BACKGROUND OF THE OFFER; CONTACTS WITH THE COMPANY.
 
  In response to the dramatic decline in defense procurement and the resulting
consolidation of the United States defense industry, Parent has and continues
to explore opportunities to expand its defense business and
 
                                       15
<PAGE>
 
to apply its defense technologies and skills in commercial markets. In the fall
of 1994, Parent began a series of discussions with Bear, Stearns & Co. Inc.
("Bear Stearns") regarding strategic alternatives available to Parent in order
to achieve these objectives. Based on public information, Bear Stearns analyzed
a number of possible acquisitions by Parent, including an acquisition of the
Company. Bear Stearns informed Parent that it was familiar with the Company and
had held discussions with the Company concerning the Company's strategic
alternatives.
 
  In January 1995, Bear Stearns arranged and attended a meeting between Dennis
J. Picard, Chairman and Chief Executive Officer of Parent, and A. Lowell
Lawson, Chairman and Chief Executive Officer of the Company. Prior to this
meeting, there had been no contacts between Parent and the Company with respect
to any possible business combination between them. At the meeting, each of
Messrs. Picard and Lawson discussed his company's strategic goals and agreed to
consider in greater detail a possible acquisition of the Company by Parent. To
this end, meetings of senior management of Parent and the Company and
representatives of Bear Stearns were held in late January, February and early
March of 1995. In addition, on January 23, 1995, Parent and the Company entered
into a confidentiality agreement providing for the disclosure by the Company of
certain non-public information to Parent.
 
  On March 23, 1995, Messrs. Picard and Lawson agreed to begin detailed
negotiations of an acquisition by Parent of the Company. Parent began an
intensive due diligence review of the Company on March 25, 1995. Negotiation of
the Merger Agreement commenced on March 28, 1995 and was concluded on April 2,
1995 with the unanimous approval of the Merger Agreement by the boards of
directors of Parent and the Company and the execution of the Merger Agreement.
 
11. PURPOSE OF THE OFFER; THE MERGER AGREEMENT; STATUTORY REQUIREMENTS;
   APPRAISAL RIGHTS; PLANS FOR THE COMPANY; THE RIGHTS.
 
  Purpose. The purpose of the Offer and the Merger is to acquire control of,
and the entire equity interest in, the Company.
 
  The Merger Agreement. The following summary description of the Merger
Agreement is qualified in its entirety by reference to such agreement, which
has been filed as an exhibit to the Tender Offer Statement on Schedule 14D-1
filed with the Commission by Parent and Purchaser (the "Schedule 14D-1"), which
may be examined and copies obtained as set forth in Section 8 above (except
that it will not be available at the regional offices of the Commission).
 
  The Merger Agreement provides that in accordance with the provisions thereof
and the General Corporation Law of the State of Delaware (the "DGCL"), at the
date and time when the Merger shall become effective pursuant to Section 2.02
of the Merger Agreement (the "Effective Time"), the Purchaser will be merged
with and into the Company, and the Company will be the surviving corporation
(hereinafter sometimes called the "Surviving Corporation") and continue its
corporate existence under the laws of the State of Delaware. At the Effective
Time the separate existence of the Purchaser shall cease.
 
  Pursuant to the Merger Agreement, as of the Effective Time, by virtue of the
Merger and without any action on the part of the holders thereof, each Share
issued and outstanding immediately prior to the Effective Time (other than any
Shares held by Parent, the Purchaser, any subsidiary of Parent or the Purchaser
or in the treasury of the Company which Shares, by virtue of the Merger and
without any action on the part of the holder thereof, shall be cancelled and
retired and shall cease to exist with no payment being made with respect
thereto, and other than any Dissenting Shares) will be converted into the right
to receive $64.00 net to its holder in cash or any higher price per Share paid
in the Offer, payable to the holder thereof, without interest thereon, upon
surrender of the certificate formerly representing such Share.
 
  For a description of certain appraisal rights available to stockholders under
the DGCL in connection with the Merger, see "Appraisal Rights" below in this
Section 11.
 
                                       16
<PAGE>
 
  As of the Effective Time, by virtue of the Merger and without any action on
the part of the holders thereof, each share of capital stock of the Purchaser
issued and outstanding immediately prior to the Effective Time will be
converted into and become one fully paid and nonassessable share of Common
Stock, par value $1.00 per share, of the Surviving Corporation.
 
  Under the Merger Agreement, the Company has agreed to take all actions
necessary to provide that immediately prior to consummation of the Offer (i)
each outstanding option to purchase Shares (the "Options") granted under the
Company's 1980 Stock Option Plan, 1982 Incentive Stock Option Plan, 1988
Employee Stock Option Plan or 1994 Employee Stock Option Plan, in each case as
amended (collectively, the "Option Plans"), whether or not then exercisable or
vested, will become fully exercisable and vested, (ii) each Option which is
then outstanding will be cancelled and (iii) in consideration of such
cancellation, and except to the extent that Parent or the Purchaser and the
holder of any such Option otherwise agree, the Company (or, at Parent's option,
Parent or the Purchaser) will pay to such holders of Options an amount in
respect thereof equal to the product of (A) the excess, if any, of the Merger
Price over the exercise price thereof and (B) the number of Shares subject
thereto (such payment to be net of applicable withholding taxes); provided that
the foregoing shall not require any action which violates the Option Plans. The
Merger Agreement provides that if it is determined that compliance with any of
the foregoing would cause any individual subject to Section 16 of the Exchange
Act to become subject to the profit recovery provisions thereof, any Options
held by such individual will be cancelled or purchased, as the case may be, as
promptly thereafter as possible so as not to subject such individual to any
liability pursuant to Section 16, and such individual will be entitled to
receive from the Company or the Surviving Corporation at the Effective Time or
as soon as practicable thereafter (or, if later, the date six months and one
day following the grant of such option), for each Share subject to an Option,
an amount equal to the excess, if any, of the Merger Price over the exercise
price of such Option.
 
  Except as provided in the Merger Agreement or as otherwise agreed to by the
parties and to the extent permitted by the Option Plans (i) the Option Plans
will terminate as of the Effective Time and the provisions in any other plan,
program or arrangement providing for the issuance or grant by the Company or
any of its subsidiaries of any interest in respect of the capital stock of the
Company or any of its subsidiaries (other than the 1994 Employee Stock Option
Plan (the "EMASS Option Plan") of EMASS, Inc. ("EMASS"), a subsidiary of the
Company) will be deleted as of the Effective Time and (ii) the Company will use
all reasonable efforts to ensure that following the Effective Time no holder of
Options or any participant in any Option Plan or any other such plans, programs
or arrangements (other than the EMASS Option Plan) shall have any right
thereunder to acquire any equity securities of the Company, the Surviving
Corporation or any subsidiary thereof. The Merger Agreement also provides that
options outstanding as of the date of the Merger Agreement to purchase not more
than 920,000 shares of common stock of EMASS pursuant to the EMASS Option Plan
will become fully vested upon consummation of the Offer and remain outstanding
after the Effective Time, and also provides that additional options to purchase
up to 150,000 shares of common stock of EMASS may be granted at the Company's
or EMASS's discretion prior to the Control Date.
 
  Pursuant to the Merger Agreement, the Company has agreed to take all actions
to provide that each share of restricted stock granted under the Option Plans
shall become fully vested and free of restrictions immediately prior to the
consummation of the Offer and that any holder of restricted stock may elect to
authorize the Company to retain a number of Shares from such grant having an
aggregate value (based upon $64.00 per Share) equal to the sum of (i) the
aggregate purchase price for such Shares under the applicable Option Plan and
(ii) any withholding taxes applicable to the vesting of such grant, in lieu of
the payment of such amounts in cash.
 
  The Merger Agreement provides that the Certificate of Incorporation and By-
Laws of the Purchaser will be the Certificate of Incorporation and By-Laws of
the Surviving Corporation until thereafter amended as provided by law, except
that the name of the Surviving Corporation will be "E-Systems, Inc."
 
  Under the Merger Agreement the directors of the Purchaser immediately prior
to the Effective Time will be the initial directors of the Surviving
Corporation and will hold office until their respective successors are duly
elected and qualified, or their earlier death, resignation or removal. The
officers of the Company
 
                                       17
<PAGE>
 
immediately prior to the Effective Time will be the initial officers of the
Surviving Corporation and will hold office until their respective successors
are duly elected and qualified, or their earlier death, resignation or removal.
 
  AGREEMENTS OF THE COMPANY, PARENT AND THE PURCHASER. The Merger Agreement
provides that, if required by applicable law in order to consummate the Merger,
the Company, acting through its Board of Directors, shall, in accordance with
applicable law, duly call, give notice of, convene and hold a special meeting
of its stockholders (the "Special Meeting") as soon as practicable following
the purchase of and payment for Shares by the Purchaser pursuant to the Offer
for the purpose of considering and adopting Merger Agreement and such other
matters as may be necessary to consummate the transactions contemplated in the
Merger Agreement.
 
  Under the Merger Agreement, in the event that Parent, the Purchaser or any
other subsidiary of Parent acquires at least 90% of the outstanding Shares
pursuant to the Offer or otherwise, at the request of Parent or the Purchaser,
Parent, the Purchaser and the Company will take all necessary and appropriate
action to cause the Merger to become effective as soon as practicable after the
acceptance for payment and purchase of Shares by the Purchaser pursuant to the
Offer without a meeting of stockholders of the Company in accordance with
Section 253 of the DGCL.
 
  In the Merger Agreement, the Company has covenanted and agreed that, except
as contemplated by the Merger Agreement or as expressly agreed to in writing by
Parent, during the period from the date of the Merger Agreement to the Control
Date (as defined in "Directors" below in this Section 11), each of the Company
and its subsidiaries will conduct its operations according to its ordinary
course of business consistent with past practice and will use commercially
reasonable efforts to preserve intact its business organization, to keep
available the services of its key employees and to maintain satisfactory
relationships with material suppliers, distributors, customers and others
having business relationships with it and will take no action not required by
law that would materially adversely affect the ability of the parties to
consummate the transactions contemplated by the Merger Agreement or be
materially inconsistent with such transactions.
 
  In the Merger Agreement, the Company has covenanted and agreed that prior to
the Control Date it will keep Parent advised of the status of all discussions
and negotiations concerning possible acquisitions and dispositions by it or any
of its subsidiaries of any corporations or businesses, and has further agreed
that without the prior written consent of Parent it will not make, or agree to
make, any such acquisition or disposition; provided that the foregoing
restriction shall not apply to certain transactions previously disclosed by the
Company to Parent. Decisions regarding other acquisitions or dispositions will
be made by the chief executive officers of Parent and the Company.
 
  Under the Merger Agreement, the Company has agreed that prior to the
Effective Time it will not, and will not authorize or permit any of its
subsidiaries or any of its or its subsidiaries' directors, officers, employees,
agents or representatives, directly or indirectly, to solicit, initiate,
facilitate or encourage (including by way of furnishing or disclosing non-
public information) any inquiries or the making of any proposal with respect to
any merger, consolidation or other business combination involving the Company
or its subsidiaries or acquisition of all or substantially all of the assets or
capital stock of the Company and its subsidiaries taken as a whole (an
"Acquisition Transaction") or negotiate, explore or otherwise engage in
substantive discussions with any person (other than Parent, the Purchaser or
their respective directors, officers, employees, agents and representatives)
with respect to any Acquisition Transaction or enter into any agreement,
arrangement or understanding requiring it to abandon, terminate or fail to
consummate the Merger or any other transactions contemplated by the Merger
Agreement; provided that the Company may in response to an unsolicited written
proposal with respect to an Acquisition Transaction from a third party furnish
information to such third party; negotiate, explore or otherwise engage in
substantive discussions with such third party; and enter into any such
agreement, arrangement or understanding, in each case only if the Board of
Directors of the Company determines in good faith by a majority vote, after
consultation with its
 
                                       18
<PAGE>
 
financial advisors and outside legal counsel, that failing to take such action
would create a reasonable possibility of a breach of the fiduciary duties of
the Board of Directors of the Company in connection with seeking an Acquisition
Transaction that is more favorable to the stockholders of the Company than the
Offer and the Merger. The Company has agreed to advise Parent immediately in
writing of the receipt of any inquiries or proposals relating to an Acquisition
Transaction and any actions described in this paragraph, unless the Company's
Board of Directors determines in good faith by a majority vote, after
consultation with its outside legal counsel, that taking such action would
create a reasonable possibility of a breach of the fiduciary duties of the
Company's Board of Directors in connection with seeking an Acquisition
Transaction that is more favorable to the stockholders of the Company than the
Offer and the Merger.
 
  Pursuant to the Merger Agreement, from the date of the Merger Agreement until
the Effective Time, and subject to any access, disclosure, copying or other
limitations imposed by applicable law or the terms of any of the Company's or
its subsidiaries' classified contracts (including any such contracts or
arrangements with the U.S. or foreign governments), the Company has agreed to
give Parent and its authorized representatives (including counsel,
environmental and other consultants, accountants and auditors) access during
normal business hours upon reasonable prior notice to all facilities, personnel
and operations and to all books and records of the Company and its
subsidiaries, and to permit Parent to make such inspections as it may
reasonably require and to cause its officers and those of its subsidiaries to
furnish Parent with such financial and operating data and other information
with respect to its business and properties as Parent may from time to time
reasonably request. Pursuant to the Merger Agreement, Parent has agreed that
any information furnished to Parent, its subsidiaries or its authorized
representatives will be subject to provisions of the letter agreement dated
January 23, 1995 between Parent and the Company.
 
  The Merger Agreement provides that, subject to the terms and conditions
therein provided and applicable law, each of the Company, Parent and the
Purchaser will use its reasonable best efforts promptly to consummate the
transactions contemplated by the Merger Agreement, including, without
limitation using such reasonable best efforts to (i) obtain all necessary
consents, approvals or waivers under its material contracts and (ii) lift any
legal bar to the Merger; provided, however, that the foregoing will not require
Parent, the Purchaser or any other affiliate of Parent to agree to any action
or restriction which, if imposed by a governmental entity, would constitute a
condition described in paragraph (A) of Section 14.
 
  Under the Merger Agreement, before issuing any press release or otherwise
making any public statements with respect to the Merger Agreement, the Offer or
the Merger, Parent, the Purchaser and the Company will consult with each other
as to its form and substance and will not issue any such press release or make
any such public statement prior to such consultation, except in either case as
may be required by law or any obligations pursuant to any listing agreement
with any national securities exchange.
 
  Under the Merger Agreement, from and after the Effective Time, Parent will
and will cause the Surviving Corporation to indemnify, defend and hold harmless
the present and former officers, directors, employees and agents of the Company
and its subsidiaries against all losses, claims, damages, expenses or
liabilities arising out of or related to actions or omissions or alleged
actions or omissions occurring at or prior to the Effective Time (i) to the
full extent permitted by Delaware law or, if the protections afforded thereby
to an indemnified person are greater, (ii) to the same extent and on the same
terms and conditions (including with respect to advancement of expenses)
provided for in the Company's Certificate of Incorporation and By-Laws and
agreements in effect at the date of the Merger Agreement (to the extent
consistent with applicable law), which provisions will survive the Merger and
continue in full force and effect after the Effective Time.
 
  Pursuant to the Merger Agreement, for a period of six years after the
Effective Time, Parent has agreed to cause to be maintained in effect the
current policies of directors' and officers' liability insurance maintained by
the Company (provided that Parent may substitute therefor policies with
reputable and financially sound carriers of at least the same coverage and
amounts containing terms and conditions which are no less advantageous) with
respect to claims arising from or related to facts or events which occurred at
or before the Effective Time; provided, however, that Parent is not obligated
to make annual premium payments for
 
                                       19
<PAGE>
 
such insurance to the extent such premiums exceed 250% of the annual premiums
paid as of the date of the Merger Agreement by the Company for such insurance.
 
  Parent has agreed pursuant to the Merger Agreement that following
consummation of the Offer, it will cause the Company to honor in accordance
with their terms certain existing employment contracts and employee benefits in
effect on the date of the Merger Agreement and as amended as contemplated by
the Merger Agreement and has further agreed to guarantee unconditionally the
prompt payment when due of all amounts payable pursuant to the terms of such
employment contracts and arrangements. In addition, Purchaser has agreed in the
Merger Agreement to provide or cause the Company to provide to individuals who
are employed by the Company or any of its subsidiaries until the third
anniversary of the Effective Time employee benefits that are in the aggregate
no less favorable than those provided to them as of the date hereof. Employees
of the Surviving Corporation will be eligible to participate in Parent's
various compensation plans on a basis comparable to that of similarly situated
employees of the Parent and its subsidiaries. The Company has also agreed to
take all steps necessary to ensure that none of the transactions contemplated
by the Merger Agreement will constitute a "change of control" as defined in
certain of the Company's retirement plans.
 
  Parent and the Purchaser have agreed in the Merger Agreement that prior to
the consummation of the Offer, the Company's Board of Directors (and following
consummation of the Offer and prior to the Effective Time, a majority of the
Continuing Directors (as hereinafter defined)) may (i) amend the Company's
employee stock ownership plan (the "ESOP") to provide for full vesting of all
account balances and allocations of all unallocated shares, or the proceeds
thereof, as of the Effective Time, and to make other technical or
administrative amendments related thereto, (ii) terminate the ESOP as of the
Effective Time and provide for the orderly liquidation of the assets thereof
or, with the consent of Purchaser (which consent shall not be unreasonably
withheld), merge the ESOP with and into another tax-qualified plan, (iii) amend
the Company's employee savings plan to increase, as of the Effective Time, the
Company's contributions thereunder to reflect any cessation of ESOP
contributions (net of contributions for the benefit of employees of the
Surviving Corporation under Parent's employee stock ownership plan ("Parent's
ESOP"), as described in the succeeding sentence), (iv) authorize amendments to
the employment contract with the Company's Chairman and Chief Executive Officer
to provide that such individual shall serve as Chief Executive Officer of the
Surviving Corporation following the Effective Time and (unless he earlier
resigns) for a period of 3 years thereafter. Parent and the Purchaser also
agreed in the Merger Agreement that if contributions to the ESOP cease on or
after the Effective Time, then as of the date of such cessation, the employees
of the Surviving Corporation and its subsidiaries who would otherwise have been
eligible to receive allocations under the ESOP shall be eligible to participate
in Parent's ESOP as of the date of such cessation. For purposes of the
preceding sentence, all service with the Company and its subsidiaries shall be
recognized for eligibility and vesting purposes.
 
  Parent has acknowledged in the Merger Agreement that the Company's business
presents special situations with respect to the retention and recruitment of
employees and executives and Parent agrees that the Chief Executive Officer of
the Company may from time to time propose special arrangements for such
employees and executives for consideration by Parent. Parent also has
acknowledged in the Merger Agreement that there are approximately 20 key
executives of the Company who, in accordance with the usual procedures of the
Compensation Committee of Parent, will receive appropriate consideration in
connection with the grant of stock options by Parent at the customary time in
July 1995.
 
  Parent and the Purchaser have acknowleged in the Merger Agreement that they
have been informed of the Company's business plan for EMASS and that they are
aware of the Company's commitment to implement that plan so long as it
represents sound business judgment. Parent and the Purchaser have also
acknowledged in the Merger Agreement that although Parent does not currently
have sufficient information to commit to a specific course of action, Parent
and the Purchaser currently plan to pursue and implement, within the same time
frames and upon the same terms and conditions, that portion of such business
plan that contemplates a public offering, spin-off or similar transaction with
respect to the capital stock of EMASS so long as the management of the
Purchaser and Parent concur with the management of the Company that plan
implementation represents the exercise of sound business judgment.

  RIGHTS AGREEMENT. In the Merger Agreement, the Company has represented that
the Company's Board of Directors has taken all necessary action (i) to provide
that neither Parent nor the Purchaser will become an "Acquiring Person," that
no "Trigger Event," "Shares Acquisition Date" or "Distribution Date" (as such
terms are defined in the Rights Agreement) will occur and that Section 13 of
the Rights Agreement will not be triggered, in each case as a result of the
announcement, commencement or consummation of the Initial Offer (as defined in
the Merger Agreement) or the Offer, the execution or delivery of the Merger
Agreement or any amendment thereto or the consummation of the transactions
contemplated thereby and (ii) to redeem the Rights effective immediately prior
to the Purchaser's acceptance of Shares for purchaser in the Offer.
 
  In the Merger Agreement, the Company has covenanted that, except as
contemplated by the preceding paragraph, the Company will not redeem the Rights
or amend or terminate the Rights Agreement prior to the consummation of the
Offer unless (i) required to do so by order of a court of competent
jurisdiction, (ii) the Company's Board of Directors determines in good faith by
a majority vote that the failure to make such redemption, amendment or
termination would create a reasonable possibility of a breach of such board's
fiduciary duties under applicable law or (iii) the Merger Agreement has
theretofore been terminated.
 
  DIRECTORS. In the Merger Agreement, Parent has agreed as promptly as
practicable after the Effective Time to appoint A. Lowell Lawson a director of
Parent for a term expiring at the 1998 annual meeting of stockholders of
Parent. In addition, it is expected that Mr. Lawson will be appointed an
executive vice president of Parent.
 
  In the Merger Agreement, the Company has agreed that, subject to compliance
with the DGCL, the Company's Certificate of Incorporation and other applicable
law, promptly upon the payment by the Purchaser for Shares purchased pursuant
to the Offer, and from time to time thereafter, the Company will, upon request
of Parent, promptly use its best efforts to take all actions necessary to cause
a majority of the directors of the Company to consist of Parent's designees,
including by accepting the resignations of those incumbent directors designated
by the Company or increasing the size of the Company's Board of Directors and
causing Parent's designees to be elected. (The date on which Purchaser's
designees constitute at least a majority of the Company's Board of Directors is
hereinafter referred to as the "Control Date.") The Company's obligations to
appoint Parent's designees to the Board are subject to Section 14(f) of the
Exchange Act and Rule 14f-1 thereunder, if applicable. Following the election
or appointment of Parent's designees as described in this paragraph and prior
to the Effective Time, any amendment or termination of the Merger Agreement by
the Company or the Company's Board of Directors, any extension by the Company
or the Company's Board of Directors, of the time for the performance of any of
the obligations or other acts of Parent or the Purchaser or waiver of any of
the Company's rights hereunder, will require the concurrence of, and only will
be effective if approved by, a majority of the directors of the Company then in
office who are not affiliated with Parent and were not designated by Parent and
(i) were also non-management directors of the Company on the date of the Merger
Agreement or (ii) were elected subsequent to the date of the Merger Agreement
by, or on the recommendation of (A) directors who were directors on the date of
the Merger Agreement or (B) the Continuing Directors (the persons referred to
in clauses (i) and (ii) being the "Continuing Directors"), even if such
majority of the Continuing Directors does not constitute a majority of all
directors then in office. Until the Effective Time, the Company's Board of
Directors shall include three Continuing Directors (subject to their
availability and willingness to serve).
 
  ADVISORY BOARD. Pursuant to the Merger Agreement, during the five-year period
immediately following the Control Date, the Company will maintain an Advisory
Board for the purpose of consulting on matters related to the business of the
Company. The members of the Advisory Board shall be chosen by mutual agreement
of the chief executive officers of the Company and the Parent from among the
individuals who constitute the Company's Board of Directors on the date of the
Merger Agreement, including any of the Continuing Directors, and
representatives of Parent. Parent shall provide or cause the Company to provide
to any members of the Advisory Board that are Continuing Directors compensation
and benefits that in the aggregate are no less favorable than those provided to
the Company's directors as of the date of the Merger
 
                                       21
<PAGE>
 
Agreement. Purchaser agrees that it will pay, or will cause the Surviving
Corporation to pay, in accordance with the terms of the director retirement
policy and executive perquisites for outside board directors of the Company in
effect as of the date of the Merger Agreement, the retirement benefit and
perquisites provided for therein to those directors who are directors of the
Company on the date of the Merger Agreement and who, after either the Control
Date or the Effective Time, do not continue on the Company's Board of Directors
or become members of the Advisory Board.
 
  REPRESENTATIONS AND WARRANTIES. The Merger Agreement contains certain
representations and warranties by the Company, including representations and
warranties concerning: the organization and qualification of the Company and
its subsidiaries; the capitalization of the Company; the authority of the
Company relative to the execution and delivery of, and consummation of the
transactions contemplated by, the Merger Agreement and approval by the Board of
Directors of the Company regarding certain related matters; the absence of any
violations of the corporate documents and certain instruments of the Company or
its subsidiaries or of any statute, rule, regulation, order or decree, subject
to certain exceptions; the accuracy of reports and documents filed by the
Company with the Commission since January 1, 1993 and certain financial
statements of the Company; the absence since December 31, 1994 (except as
disclosed in prior filings with the Commission) to the date of the Merger
Agreement of any event or occurrence (including the incurrence or existence of
any liability but excluding events or occurrences which relate to general
economic conditions or conditions generally affecting the defense industry)
which, individually or in the aggregate, would have a Company Material Adverse
Effect (as defined in the Merger Agreement); the absence of litigation which
could have a Company Material Adverse Effect; compliance by the Company with
applicable laws, regulations, and similar matters; payment by the Company of
taxes; compliance with certain laws relating to employee benefit plans; the
taking by the Board of Directors of the Company of all appropriate and
necessary action such that the provisions of Section 203 of the DGCL will not
apply to the transactions contemplated by the Merger Agreement; and incurrence
of broker's and similar fees.
 
  The Merger Agreement also contains certain representations and warranties by
Parent and the Purchaser, including that Parent or the Purchaser has and will
have at the time of acceptance for payment and purchase of Shares under the
Offer and at the Effective Time the funds necessary to consummate the Offer and
the Merger and the transactions contemplated thereby and to pay related fees
and expenses.
 
  CONDITIONS TO THE MERGER. Under the Merger Agreement, the respective
obligations of each party to effect the Merger are subject to the fulfillment
of each of the following conditions: (i) the Purchaser shall have accepted for
payment and paid for Shares pursuant to the Offer in accordance with the terms
thereof (this condition will be deemed to have been satisfied with respect to
the obligation of Parent and the Purchaser to effect the Merger if the
Purchaser fails to accept for payment or pay for Shares pursuant to the Offer
in violation of the terms of the Offer or the Merger Agreement); (ii) the vote
of the stockholders of the Company necessary to consummate the transactions
contemplated by the Merger Agreement shall have been obtained, if required by
applicable law; and (iii) no statute, rule, regulation, judgment, writ, decree,
order or injunction shall have been promulgated, enacted, entered or enforced,
and no other action shall have been taken, by any domestic, foreign or
supranational government or governmental, administrative or regulatory
authority or agency of competent jurisdiction or by any court or tribunal of
competent jurisdiction, domestic, foreign or supranational, that in any of the
foregoing cases has the effect of making illegal or directly or indirectly
restraining, prohibiting or restricting the consummation of the Merger.
 
  TERMINATION. The Merger Agreement may be terminated at any time prior to the
Effective Time: (i) by mutual written consent of the Boards of Directors of
Parent and the Company; (ii) by either Parent or the Company if, without any
material breach of the terminating party of its obligations under the Merger
Agreement, the purchase of Shares pursuant to the Offer shall not have occurred
on or before September 30, 1995 (which date may be extended by mutual written
consent of the parties to the Merger Agreement); (iii) by Parent or the Company
if the Offer expires or is terminated or withdrawn pursuant to its terms
without any Shares being purchased thereunder; provided, however, that Parent
may not terminate the Merger
 
                                       22
<PAGE>
 
Agreement pursuant to such provision if Parent's or the Purchaser's termination
of, or failure to accept for payment or pay for any Shares tendered pursuant
to, the Offer does not follow the occurrence, or failure to occur, as the case
may be, of any condition to the obligation of the Purchaser to accept for
payment and pay for Shares in the Offer or is otherwise in violation of the
terms of the Offer or the Merger Agreement; (iv) by either Parent or the
Company if any court of competent jurisdiction in the United States or other
governmental body in the United States shall have issued an order (other than a
temporary restraining order), decree or ruling or taken any other action
restraining, enjoining or otherwise prohibiting the purchase of Shares pursuant
to the Offer or the Merger, and such order, decree, ruling or other action
shall have become final and nonappealable; provided that the party seeking to
terminate the Merger Agreement shall have used its reasonable best efforts,
subject to certain limitations, to remove or lift such order, decree or ruling;
or (v) by the Company if the Offer has not been timely commenced.
 
  The Merger Agreement may be terminated and the Offer and the Merger may be
abandoned by action of the Board of Directors of Parent at any time prior to
the purchase of Shares pursuant to the Offer if (i) the Board of Directors of
the Company shall withdraw, modify or change its recommendation or approval in
respect of the Merger Agreement or the Offer in a manner adverse to Parent,
(ii) the Board of Directors of the Company shall have recommended any proposal
other than by Parent or the Purchaser in respect of an Acquisition Transaction,
or (iii) any corporation, partnership, person, other entity or group (as
defined in Section 13(d)(3) of the Exchange Act) other than Parent or the
Purchaser or any of their respective subsidiaries or affiliates shall have
become the beneficial owner of more than 20% of the outstanding Shares (either
on a primary or a fully-diluted basis).
 
  The Merger Agreement may be terminated and the Merger may be abandoned by
action of the Board of Directors of the Company at any time prior to the
Effective Time (i) if there shall be a material breach of any of Parent's or
the Purchaser's representations, warranties or covenants under the Merger
Agreement, which breach shall not be cured within ten days of notice thereof,
or (ii) to allow the Company to enter into an agreement in respect of an
Acquisition Transaction which the Board of Directors of the Company has
determined is more favorable to the Company and its stockholders than the
transactions contemplated by the Merger Agreement (provided that such
termination shall not be effective unless and until the Company shall have paid
to Parent the fee described in the second paragraph under "Fees and Expenses"
below).
 
  FEES AND EXPENSES. Except to the extent Parent becomes entitled to an expense
reimbursement fee as described in the following paragraph, Parent and the
Company will bear their respective expenses incurred in connection with the
Merger Agreement, the Offer and the Merger, including, without limitation, the
preparation, execution and performance of the Merger Agreement and the
transactions contemplated thereby, and all fees and expenses of investment
bankers, finders, brokers, agents, representatives, counsel and accountants.
 
  If (i) Parent shall have terminated the Merger Agreement as described in the
second paragraph of "Termination" above or (ii) the Company shall have
terminated the Merger Agreement as described in clause (ii) of the third
paragraph of "Termination" above, then the Company shall promptly, but in no
event later than two business days after the date of such termination or event,
pay Parent an expense reimbursement fee of $75,000,000 plus an amount, not in
excess of $20,000,000, equal to Parent's actual and reasonably documented out-
of-pocket expenses directly attributable to the negotiation and execution of
this Agreement and the attempted financing and completion of the Offer and the
Merger, which amount shall be payable in same day funds, provided that no fee
or expense reimbursement shall be paid as described in this paragraph if Parent
shall be in material breach of its obligations under the Merger Agreement.
 
  AMENDMENT. At any time prior to the Effective Time, subject to applicable law
and the provisions of the Merger Agreement described above relating to
approvals by Continuing Directors, the Merger Agreement may be amended,
modified or supplemented only by written agreement of Parent, the Purchaser and
the Company with respect to any of the terms contained therein; provided,
however, that after any approval and
 
                                       23
<PAGE>
 
adoption of the Merger Agreement by the stockholders of the Company, no such
amendment, modification or supplementation shall be made which reduces the
amount of per-share consideration paid in the Merger or the form of
consideration therefor or which in any way materially adversely affects the
rights of such stockholders without the further approval of such stockholders.
 
  WAIVERS. At any time prior to the Effective Time, Parent and the Purchaser,
on the one hand, and the Company, on the other hand, may (i) extend the time
for the performance of any of the obligations or other acts of the other, (ii)
waive any inaccuracies in the representations and warranties of the other
contained herein or in any documents delivered pursuant hereto or (iii) waive
compliance by the other with any of the agreements or conditions contained
herein which may legally be waived. Any such extension or waiver shall be valid
only if set forth in an instrument in writing specifically referring to this
Agreement and signed on behalf of such party.
 
  EFFECTS OF INABILITY TO CONSUMMATE THE MERGER. Pursuant to the Merger
Agreement following the consummation of the Offer subject to certain other
conditions, the Purchaser will be merged with the Company. If, following the
Offer, approval of the Company's stockholders is required by applicable law in
order to consummate the Merger of the Purchaser with the Company, provided that
the Minimum Condition is satisfied without being reduced or waived, the Company
will submit the Merger to the Company's stockholders for approval. If the
Merger is submitted to the Company's stockholders for approval, the Merger will
require the approval of the holders of not less than 80% of the outstanding
Shares, including the Shares owned by the Purchaser. There can be no assurance
that the required vote of the shareholders will be obtained or that the Merger
will be consummated.
 
  If the Merger is consummated, stockholders of the Company who elected not to
tender their the Shares in the Offer will receive the same amount of
consideration in exchange for each Share as they would have received in the
Offer.
 
  If, following the consummation of the Offer, the Merger is not consummated,
Parent, which owns 100% of the Common Stock of the Purchaser, indirectly will
control the number of Shares acquired by the Purchaser pursuant to the Offer.
Under the Merger Agreement, promptly following payment by the Purchaser for
Shares purchased pursuant to the Offer, and from time to time thereafter,
subject to applicable law, the Company has agreed to take all actions necessary
to cause a majority of the directors of the Company selected by Parent to
consist of persons designated by Parent (whether, at the election of the
Company, by means of increasing the size of the board of directors or seeking
the resignation of directors and causing Parent designees to be elected). As a
result of its ownership of such Shares and right to designate nominees for
election to the Company's Board of Directors, Parent indirectly will be able to
influence decisions of the Board and the decisions of the Purchaser as a
stockholder of the Company. This concentration of influence in one stockholder
may adversely affect the market value of the Shares.
 
  If Parent controls more than 50% of the outstanding Shares following the
consummation of the Offer but the Merger is not consummated, stockholders of
the Company, other than those affiliated with Parent, will lack sufficient
voting power to elect directors or to cause other actions to be taken which
require majority approval. If for any reason following completion of the Offer
the Merger is not consummated, Parent and the Purchaser reserve the right to
acquire additional Shares 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 Parent and the
Purchaser.
 
  Statutory Requirements. In general, under the DGCL 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
 
                                       24
<PAGE>
 
Company Certificate of Incorporation, the Shares are the only securities of the
Company which entitle the holders thereof to voting rights.
 
  The DGCL 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 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 the Shares, the
Purchaser could, and intends to, effect the Merger without prior notice to, or
any action by, any other stockholder of the Company.
 
  Appraisal Rights. No appraisal rights are available in connection with the
Offer. However, if the Merger is consummated, stockholders of the Company will
have certain rights under Section 262 of the DGCL 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 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 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 DGCL.
 
  Plans for the Company. If Parent acquires control of the Company, it is its
present intent to operate the Company as a subsidiary under the Company's
current name, with the same management and organizational structure and in its
current headquarters in Dallas, Texas. However, Parent will 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, Parent 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. Parent'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.
 
  Except as described in this Offer to Purchase, neither Parent 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 change in the present
capitalization or dividend policy of the Company, (v) any material change in
the Company's corporate structure or business, (vi) causing
 
                                       25
<PAGE>
 
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.
 
  "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 Merger. However,
Rule 13e-3 would be inapplicable if (i) the Shares are deregistered under the
Exchange Act prior to the Merger or other business combination or (ii) the
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 in
the Merger or other business combination is at least equal to the amount paid
per 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.
 
  The Rights. According to the Company's Registration Statement on Form 8-A
dated October 12, 1994 (the "Company 8-A"), on September 28, 1994, the Board of
Directors of the Company declared a dividend distribution of one Right for each
outstanding Share to purchase one one-thousandth of a share of a new Series A
Junior Participating Preferred Stock. Each Right entitles the registered holder
of Shares to purchase from the Company one one-thousandth of a share of Series
A Junior Participating Preferred Stock at an exercise price of $130.00, 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 10 days 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 15% or more of the outstanding Shares and 10 business days (or
such later date as the Board of Directors of the Company shall determine)
following the commencement of a tender offer or exchange offer which would
result in a person or group beneficially owning 15% or more of the outstanding
Shares, (i) the Rights will be evidenced by the Share certificates and will be
transferred with and only with such Share certificates, (ii) new Share
certificates will contain a notation incorporating the Rights Agreement by
reference and (iii) the surrender for transfer of any certificates for Shares
outstanding will also constitute the transfer of the Rights associated with the
Shares represented by such certificate. As soon as practicable after the
Distribution Date, 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 close of business on October
17, 2004, unless earlier redeemed by the Company as described below.
 
  According to the Company 8-A, in the event that the Company is acquired in a
merger or consolidation in which the Company is not the surviving corporation
or 50% or more of the Company's consolidated assets or earning power is sold or
transferred (other than a merger that follows a tender offer determined to be
fair to the stockholders of the Company); 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 value
equal to two times the exercise price of the Right.
 
  According to the Company 8-A, in the event that an Acquiring Person becomes
the beneficial owner of 15% or more of the then outstanding Shares (unless such
acquisition is made pursuant to a tender or exchange offer for all outstanding
shares of the Company at a price determined by a majority of the independent
Directors of the Company who are not representatives, nominees, affiliates or
associates of an Acquiring Person to be fair and otherwise in the best interest
of the Company and its stockholders), each holder of a Right will thereafter
have the right to receive, upon exercise, Shares (or, in certain circumstances,
cash,
 
                                       26
<PAGE>
 
property or other securities of the Company), having a value equal to two times
the exercise price of the Right.
 
  According to the Company 8-A, at any time until 10 days following the Stock
Acquisition Date, the Company may redeem the Rights in whole, but not in part,
at a price of $.01 per Right (the "Redemption Price"). Immediately upon the
action of the Board of Directors of the Company ordering redemption of the
Rights, the Rights will terminate, and the only right of 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 the Distribution Date, the provisions of the
Rights Agreement and the terms of the Rights may be amended without consent of
such holders only to cure any ambiguity, make certain changes which do not
adversely affect the interests of holders of Rights (excluding the interests of
any Acquiring Person) or to shorten or lengthen any time period under the
Rights Agreement; provided that no amendment to adjust the time period
governing redemption shall be made at such time as the Rights are not
redeemable.
 
  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.
 
  STOCKHOLDERS ARE 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.
 
12. SOURCE AND AMOUNT OF FUNDS.
 
  The total amount of funds required by the Purchaser to purchase all of the
outstanding Shares pursuant to the Offer and to pay fees and expenses related
to the Offer and the Merger is expected to be approximately $2.4 billion. The
Purchaser plans to obtain all funds needed for the Offer and the Merger through
a capital contribution which will be made by Parent. Parent plans to obtain the
funds for such capital contribution pursuant to a financing commitment letter
(the "Commitment"), dated April 1, 1995, from Chemical Bank ("Chemical"),
Chemical Securities Inc. ("Chemical Securities"), Bank of America National
Trust and Savings Association ("BA"), BA Securities, Inc. ("BA Securities"),
The Chase Manhattan Bank, N.A. ("Chase") and Chase Securities, Inc. ("Chase
Securities"). Set forth below is a summary of the principal terms of the
Commitment.
 
  Pursuant to the Commitment, each of Chemical, BA and Chase (collectively the
"Managing Agents") have agreed to provide $1 billion of a $3 billion, five-
year, unsecured, competitive advance/revolving credit facility (the
"Facility"). The proceeds of the Facility may be used to finance the
acquisition of Shares pursuant to the Offer and the Merger and, following the
Merger, to provide working capital to, and for other general corporate purposes
of, Parent, including for commercial paper back-up.
 
  The Commitment is conditioned upon: (i) the satisfaction of each of the
Managing Agents with the structure and terms of the Offer and the Merger, all
legal, tax and accounting matters relating to the Offer and the Merger and all
other agreements to be entered into in connection therewith; (ii) the absence
of any material adverse change since December 31, 1994 in the business, assets,
condition (financial or otherwise) or
 
                                       27
<PAGE>
 
prospects of Parent and its subsidiaries taken as a whole; (iii) the
negotiation, execution and delivery of definitive credit documentation
satisfactory to the Managing Agents; (iv) there not having occurred and be
continuing an adverse change in financial, banking or capital market conditions
since the April 1, 1995 that in the reasonable judgment of Chemical Securities,
BA Securities and Chase Securities (collectively the "Agents") would have a
material adverse effect on the syndication of the Facility; and (v) the
satisfaction of the Agents that following the date of the Commitment and during
the syndication of the Facility Parent and its subsidiaries shall not have
offered, placed or arranged to be in the process of offering, placing or
arranging any competing issues of debt securities (other than commercial paper)
or competing bank credit facilities of Parent or its subsidiaries.
 
  Two borrowing options will be available under the Facility: a competitive
advance option (the "CAF") and a revolving credit option. Under the CAF, up to
the full aggregate amount of the commitments under the Facility (less any
amounts outstanding as revolving credit loans) may be borrowed, repaid and
reborrowed at the discretion of the lenders who may elect to bid in accordance
with certain auction procedures described in the Commitment. Under the
revolving credit option, up to the full aggregate amount of the commitments
under the Facility (less any amounts outstanding as CAF loans) may be borrowed,
repaid and reborrowed subject only to the satisfaction of applicable conditions
to borrowing.
 
  Interest rates under the CAF will be the rates obtained from bids as selected
by Parent in accordance with the procedures outlined in the Commitment.
Interest rates under the revolving credit option will be at the option of
Parent either (i) the London Interbank Offered Rate (LIBOR) plus spreads
projected to range from 18.75 basis points to 25 basis points depending on
Parent's debt rating or (ii) the highest of (A) Chemical's Prime Rate, (B) the
base CD rate plus 1% and (C) the federal funds effective rate plus 1/2 of 1%.
 
  The credit agreement relating to the Facility will contain customary
representations and warranties and events of default.
 
  Parent has agreed to pay the Managing Agents and the Agents customary
commitment and facility fees as well as certain of the fees and expenses of the
Managing Agents and the Agents and their affiliates arising in connection with
the Commitment and the Financing. In addition, Parent has agreed to indemnify
each of the Managing Agents and the Agents and certain related persons against
certain damages and expenses arising out of any investigation or litigation
relating to the Commitment, the Financing and the acquisition by Parent of the
Company.
 
  No final decisions have been made concerning the method Parent will employ to
refinance and repay the indebtedness incurred by Parent under the Facility.
Such decisions will be based on Parent's review from time to time of the
advisability of particular actions, including the availability of cash flow
generated by Parent, prevailing interest rates, market conditions and other
financial and economic conditions.
 
  The foregoing summary of the Commitment is qualified in its entirety by
reference to the Commitment, which is filed as an exhibit to the Schedule 14D-
1.
 
13. DIVIDENDS AND DISTRIBUTIONS.
 
  If on or after the date of the Merger Agreement 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 the date of the Merger Agreement under option and employee stock
purchase plans in accordance with their terms as publicly disclosed as of the
date of the Merger Agreement) 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 as it deems
 
                                       28
<PAGE>
 
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 the date of the Merger Agreement the Company declares or pays
any dividend on the Shares (other than regular quarterly cash dividends at a
rate not exceeding $.375 per Share per quarter, payable on the Company's
customary dividend payment dates) 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, 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 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) promulgated under the

tendered Shares promptly after termination or withdrawal of the Offer), pay
for, and may delay the acceptance for payment of any tendered Shares and,
except as set forth in the Merger Agreement, amend or terminate the Offer as to
any Shares not then paid for if (i) the Minimum Condition shall not have been
satisfied, (ii) any applicable waiting period under the HSR Act shall not have
expired or been terminated prior to the expiration of the Offer or (iii) at any
time after execution of the Merger Agreement and before the time of payment for
any such Shares (whether or not any Shares have theretofore been accepted for
payment or paid for pursuant to the Offer), any of the following conditions
exists:
 
    (A) there shall be in effect an injunction or other order, decree,
  judgment or ruling by a court of competent jurisdiction or by a
  governmental, regulatory or administrative agency or commission of
  competent jurisdiction or a statute, rule, regulation, executive order or
  other action shall have been promulgated, enacted, taken or threatened by a
  governmental authority or a governmental, regulatory or administrative
  agency or commission of competent jurisdiction which in any such case (I)
  restrains or prohibits the making or consummation of the Offer or the
  consummation of the Merger, (II) prohibits or restricts the ownership or
  operation by Parent or the Purchaser (or any of their respective affiliates
  or subsidiaries) of any portion of its or the Company's business or assets
  which is material to the business of all such entities taken as a whole, or
  compels Parent or the Purchaser (or any of their respective affiliates or
  subsidiaries) to dispose of or hold separate any portion of its or the
  Company's business or assets which is material to the business of all such
  entities taken as a whole, (III) imposes material limitations on the

  limitations on the ability of Parent or the Purchaser or any of their
  respective affiliates or subsidiaries effectively to control in any
  material respect the business and operations of the Company
 
                                       29
<PAGE>
 
  and its subsidiaries, or (V) which otherwise would materially adversely

    (B) the Merger Agreement shall have been terminated by the Company,
  Parent or the Purchaser in accordance with its terms; or
 
    (C) (I) the representations and warranties made by the Company in the

  (II) as of the Expiration Date the Company shall not in all material
  respects have performed its material obligations and agreements and

  Agreement through the date of termination or expiration of the Offer, a

  Merger Agreement, a material acceleration or worsening thereof; or
 
    (E) Parent, the Purchaser and the Company shall have agreed that the

  payment for Shares pursuant thereto.
 
  The foregoing conditions are for the sole benefit of Parent and the Purchaser
and may be asserted by Parent or the Purchaser regardless of the circumstances
(including any action or inaction by Parent or the Purchaser) giving rise to
any such conditions and may be waived by Parent or the Purchaser in whole or in
part at any time and from time to time, in each case, in the exercise of the
good faith judgment of Parent and the Purchaser and subject to the terms of the
Merger Agreement. The failure by Parent or the Purchaser at any time to
exercise any of the foregoing rights shall not be deemed a waiver of any such
right and each such right shall be deemed an ongoing right which may be
asserted at any time and from time to time.
 
  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 (i) if the
Purchaser is delayed in accepting the Shares it must either extend the Offer or
terminate the Offer and promptly return the Shares and (ii) 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 most required
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
information regarding the Company, neither Parent 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 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
 
                                       30
<PAGE>
 
Company's, Parent'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 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 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. 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 Merger. The Purchaser reserves the right to
challenge the validity or applicability of any state law allegedly applicable
to the Offer or the 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 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 Offer or the
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 FTC and the Antitrust
Division of the Department of Justice (the "Antitrust Division") and certain
waiting period requirements have been satisfied. The acquisition of Shares
pursuant to the Offer and the Merger is subject to such requirements.
 
  Under the provisions of the HSR Act applicable to the Offer and the Merger,
the purchase of Shares pursuant to the Offer and the 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
 
                                       31
<PAGE>
 
FTC and the Antitrust Division. The Purchaser expects to file a Premerger
Notification and Report Form with the FTC and the Antitrust Division in
connection with the purchase of Shares pursuant to the Offer and the Merger
under the HSR Act on April 3, 1995, and, in such event, the required waiting
period with respect to the Offer and the Merger will expire at 11:59 p.m., New
York City time, on April 18, 1995, unless earlier terminated by the FTC or the
Antitrust Division 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 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 FTC and the Antitrust Division in
connection with the Offer, neither the Company's failure to make such filings
nor a request made to the Company from the FTC or the Antitrust Division for
additional information or documentary material will extend the waiting period
with respect to the purchase of Shares pursuant to the Offer and the Merger.
 
  The FTC and the Antitrust Division 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 Merger. At any time before or after the
Purchaser's purchase of Shares, the FTC or the Antitrust Division 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 Merger, the divestiture of Shares purchased
pursuant to the Offer or the divestiture of substantial assets of Parent, 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 Merger should not violate
the applicable antitrust laws. Nevertheless, there can be no assurance that a
challenge to the Offer and the Merger on antitrust grounds will not be made,
or, if such challenge is made, what the result will be. See Section 14.
 
  Foreign Approvals. According to publicly available information, the Company
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 Merger, the laws of certain of those foreign countries and
jurisdictions may require the filing of information with, or the obtaining of
the approval or consent 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 countries and jurisdictions as a result of the acquisition of the
Shares pursuant to the Offer or the Merger. If such approvals or consents are
found to be required the parties intend to make the appropriate filings and
applications. In the event such a filing or application is made for the
requisite foreign approvals or consents, there can be no assurance that such
approvals or consents will be granted and, if such approvals or consents are
received, there can be no assurance as to the date of such approvals or
consents. In addition, 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 Merger.
 
16. CERTAIN FEES AND EXPENSES.
 
  Bear Stearns is acting as Dealer Manager in connection with the Offer and as
financial advisor to Parent and the Purchaser in connection with the proposed
acquisition of the Company. Parent has paid or is obligated to pay to Bear
Stearns a fee of $5,000,000 and has agreed to pay Bear Stearns additional fees
of
 
                                       32
<PAGE>
 
$5,000,000 upon commencement of the Offer and $4,000,000 if the acquisition of
the Company by Parent is completed. In addition, Parent has agreed to reimburse
Bear Stearns for its reasonable expenses incurred in rendering its services
under its engagement agreement with Parent and has agreed to indemnify Bear
Stearns against certain liabilities and expenses in connection with the Offer
and the Merger, including certain liabilities under the federal securities
laws. Bear Stearns from time to time renders various investment banking
services to Parent and its affiliates for which it is paid customary fees.
 
  D.F. King & Co., Inc. has been retained by the Purchaser as Information Agent
in connection with the Offer. The Information Agent may contact holders of
Shares 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. 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 federal
securities laws.
 
  In addition, The First National Bank of Boston has been retained as the
Depositary. The Purchaser will pay the Depositary reasonable and customary
compensation for its services in connection with the Offer, will reimburse the
Depositary for its reasonable out-of-pocket expenses in connection therewith
and will indemnify the Depositary against certain liabilities and expenses in
connection therewith, including certain liabilities under the federal
securities laws.
 
  Except as set forth above, neither Parent nor the Purchaser will pay any fees
or commissions to any broker, dealer or other person (other than the Dealer
Manager) for soliciting tenders of Shares pursuant to the Offer. Brokers,
dealers, commercial banks and trust companies and other nominees will, upon
request, be reimbursed by Parent or 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 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.
 
  Parent and the Purchaser have filed with the Commission a Schedule 14D-1,
together with exhibits, pursuant to Rule 14d-3 of the General Rules and
Regulations under the Exchange Act, furnishing certain additional information
with respect to the Offer, and may file amendments thereto. Such Schedule 14D-1
and any amendments thereto, including exhibits, may be examined and copies may
be obtained from the office of the Commission in the same manner as described
in Section 8 with respect to information concerning the Company, except that
copies will not be available at the regional offices of the Commission.
 
  NO PERSON HAS BEEN AUTHORIZED TO GIVE ANY INFORMATION OR TO MAKE ANY
REPRESENTATION ON BEHALF OF PARENT OR THE PURCHASER NOT CONTAINED IN THIS OFFER
TO PURCHASE OR IN THE LETTER OF TRANSMITTAL AND, IF GIVEN OR MADE, ANY SUCH
INFORMATION OR REPRESENTATION MUST NOT BE RELIED UPON AS HAVING BEEN
AUTHORIZED.

the Offer shall under any circumstances create any implication that there has
been no change in the affairs of Parent, the Purchaser, the Company or any of
their respective subsidiaries since the date as of which information is
furnished or the date of this Offer to Purchase.

or the issuance of rights for the purchase of any securities, but excluding
regular cash dividends at a rate not exceeding $.375 per Share per quarter,
payable on the Company's customary dividend payment dates) with respect to the
Shares that are declared or paid by the Company on or after the date of the
Offer to Purchase and are 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 purchased
pursuant to the Offer (collectively "Distributions"), 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 Shares (and 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
Distributions), or transfer ownership of such Shares 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 Shares (and Distributions) for
transfer on the books of the Company and (c) receive all benefits and otherwise
exercise all rights of beneficial ownership of such Shares (and Distributions),
all in accordance with the terms of the Offer.

  The undersigned hereby irrevocably appoints Christoph L. Hoffmann and Sally
F. Cloyd, 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 or her substitute shall, in his or her sole
discretion, deem proper, and otherwise act (including pursuant to written
consent) with respect to all of the Shares tendered hereby which have been
accepted for payment by the Purchaser prior to the time of such vote or action
(and Distributions) which the undersigned is entitled to vote at any meeting of
stockholders of the Company (whether annual or special and whether or not an
adjourned meeting), 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 Shares and is irrevocable and is granted in consideration
of, and is effective upon, the acceptance for payment of such Shares 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 Shares (and
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 Shares to be deemed validly tendered, immediately
upon the Purchaser's acceptance for payment of such Shares, the Purchaser is
able to exercise full voting rights with respect to such Shares 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 Shares tendered
hereby (and 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 Shares tendered hereby (and
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 Shares 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 such Distributions and may withhold the entire
purchase price or deduct from the purchase price of Shares 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. Tenders of Shares pursuant to the Offer are irrevocable, except
that Shares tendered pursuant to the Offer may be withdrawn at any time on or
prior to the Expiration Date and, unless theretofore accepted for payment
pursuant to the Offer, may also be withdrawn at any time after June 1, 1995.
See Section 4 of the Offer to Purchase.
 
  The undersigned understands that tenders of Shares 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 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 return any
Share 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 that both the "Special Delivery
Instructions" and the "Special Payment Instructions" are completed, please
issue the check for the purchase price and/or return any Share 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 Shares by book-entry transfer may request that any Shares 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 Shares from the name of the registered
holder thereof if the Purchaser does not accept for payment any of such Shares.

                                  INSTRUCTIONS
 
             FORMING PART OF THE TERMS AND CONDITIONS OF THE OFFER
 
1. Guarantee of Signatures.
 
  No signature guarantee on this Letter of Transmittal is required (i) if this
Letter of Transmittal is signed by the registered holder(s) (which term, for
purposes of this document, shall include any participant in a Book-Entry
Transfer Facility whose name appears on a security position listing as the
owner of Shares) of the Shares tendered herewith, unless such holder(s) has
completed either the box entitled "Special Payment Instructions" or the box
entitled "Special Delivery Instructions" on the inside front cover hereof or
(ii) if such Shares are tendered for the account of 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"). In all other cases, all signatures on this Letter of
Transmittal must be guaranteed by an Eligible Institution. See Instruction 5.
 
2. Delivery of Letter of Transmittal and Certificates.
 
  This Letter of Transmittal is to be used either if Share Certificates are to
be forwarded herewith or, unless an Agent's Message is utilized, if tenders are
to be made pursuant to the procedures for tender by book-entry transfer set
forth in Section 3 of the Offer to Purchase. Share Certificates, or timely
confirmation of a book-entry transfer (a "Book-Entry Confirmation") of such
Shares into the Depositary's account at a Book-Entry Transfer Facility, as well
as this Letter of Transmittal (or a facsimile hereof), properly completed and
duly executed, with any required signature guarantees, or an Agent's Message in
the case of a book-entry delivery, and any other documents required by this
Letter of Transmittal, must be received by the Depositary at one of its
addresses set forth herein prior to the Expiration Date. Stockholders whose
Share Certificates are not immediately available or who cannot deliver their
Share Certificates and all other required documents to the Depositary prior to
the Expiration Date or who cannot complete the procedures for delivery by book-
entry transfer on a timely basis may tender their Shares by properly completing
and duly executing a Notice of Guaranteed Delivery pursuant to the guaranteed
delivery procedures set forth in Section 3 of the Offer to Purchase. Pursuant
to such procedure: (i) such tender must be 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, must be
received by the Depositary on or prior to the Expiration Date; and (iii) the
Share Certificates (or a Book-Entry Confirmation) representing all tendered
Shares, in proper form for transfer together with a properly completed and duly
executed Letter of Transmittal (or a 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 five New York Stock Exchange, Inc.
("NYSE") trading days after the date of execution of such Notice of Guaranteed
Delivery. If Share Certificates are forwarded separately to the Depositary, a
properly completed and duly executed Letter of Transmittal (or facsimile
hereof) must accompany each such delivery.
 
  THE METHOD OF DELIVERY OF SHARE CERTIFICATES, THIS 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.
 
  No alternative, conditional or contingent tenders will be accepted and no
fractional Shares will be purchased. All tendering stockholders, by execution
of this Letter of Transmittal or facsimile hereof, waive any right to receive
any notice of the acceptance of their Shares for payment.
 
3. Inadequate Space.
 
  If the space provided herein is inadequate, the certificate numbers and/or
the number of Shares and any other required information should be listed on a
separate schedule attached hereto and separately signed on each page thereof in
the same manner as this Letter of Transmittal is signed.
<PAGE>
 
4. Partial Tenders (Not Applicable to Stockholders who Tender by Book-Entry
Transfer).
 
  If fewer than all the Shares evidenced by any certificate submitted are to be
tendered, fill in the number of Shares which are to be tendered in the box
entitled "Number of Shares Tendered." In such case, new certificate(s) for the
remainder of the Shares that were evidenced by your old certificate(s) will be
sent to you, unless otherwise provided in the appropriate box marked "Special
Payment Instructions" and/or "Special Delivery Instructions" on this Letter of
Transmittal, as soon as practicable after the Expiration Date. All Shares
represented by certificates delivered to the Depositary will be deemed to have
been tendered unless otherwise indicated.
 
5. Signatures on Letter of Transmittal, Stock Powers and Endorsements.
 
  If this Letter of Transmittal is signed by the registered holder(s) of the
Shares tendered hereby, the signature(s) must correspond exactly with the
name(s) as written on the face of the certificate(s) without alteration,
enlargement or any change whatsoever.
 
  If any of the Shares tendered hereby are owned of record by two or more joint
owners, all such owners must sign this Letter of Transmittal.
 
  If any tendered Shares are registered in different names on several
certificates, it will be necessary to complete, sign and submit as many
separate Letters of Transmittal as there are different registrations of
certificates.
 
  If this Letter of Transmittal or any certificates or stock powers are signed
by trustees, executors, administrators, guardians, attorneys-in-fact, officers
of corporations or others acting in a fiduciary or representative 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
Shares listed and transmitted hereby, no endorsements of certificates or
separate stock powers are required unless payment is to be made to or
certificates for Shares 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 Shares 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 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 Shares not
tendered or purchased are to be registered in the name of, any person other
than the registered holder(s), 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(s) or such person) payable on account of the transfer to such
person will be deducted from the purchase price received by such holder(s)
pursuant to this Offer (i.e., such purchase price will be reduced) 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 (i) a check is to be issued in the name of and/or (ii) certificates for
unpurchased Shares 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
<PAGE>
 
Shares by book-entry transfer (i.e., Book-Entry Stockholders) may request that

Transfer Facility as such Book-Entry Stockholder may designate hereon. If no
such instructions are given, such Shares 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

Agent or to brokers, dealers, commercial banks or trust companies.
<PAGE>
 
9. 31% Backup Withholding; Substitute Form W-9.
 
  Under U.S. Federal income tax law, a stockholder whose tendered 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 Shares 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.
 
  To prevent backup withholding on payments that are made to a stockholder with
respect to Shares purchased pursuant to the Offer, the stockholder is required
to notify the Depositary of such stockholder's correct TIN by completing a
Substitute Form W-9 certifying (i) that the TIN provided on Substitute Form W-9
is correct (or that such stockholder is awaiting a TIN), and (ii) that (a) such
stockholder has not been notified by the Internal Revenue Service that such
stockholder is subject to backup withholding as a result of a failure to report
all interest or dividends or (b) the Internal Revenue Service has notified such
stockholder that such stockholder is no longer subject to backup withholding.
 
  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
Shares or of the last transferee appearing on the transfers attached to, or
endorsed on, the Shares. If the Shares 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 Shares 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 SHARE CERTIFICATES OR CONFIRMATION OF BOOK-ENTRY
TRANSFER OR A PROPERLY COMPLETED AND DULY EXECUTED NOTICE OF GUARANTEED
DELIVERY AND ALL OTHER REQUIRED DOCUMENTS MUST BE RECEIVED BY THE DEPOSITARY ON
OR PRIOR TO THE EXPIRATION DATE.

Share, net to the seller in cash, without interest thereon, upon the terms and
subject to the conditions set forth in the Offer to Purchase and in the related
Letter of Transmittal enclosed herewith. 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 (as defined in the Offer to Purchase),
including the right to receive any payment due upon redemption of the Rights.
Holders of Shares whose certificates for such Shares (the "Share Certificates")
are not immediately available, or who cannot deliver their Share Certificates
and all other required documents to the Depositary on or prior to the
Expiration Date (as defined in the Offer to Purchase), or who cannot complete
the procedures for book-entry transfer on a timely basis, must tender their
Shares according to the guaranteed delivery procedures set forth in Section 3
of the Offer to Purchase.
 
  WE ARE THE HOLDER OF RECORD OF SHARES HELD BY US FOR YOUR ACCOUNT. A TENDER
OF SUCH SHARES CAN BE MADE ONLY BY US AS THE HOLDER OF RECORD AND PURSUANT TO
YOUR INSTRUCTIONS. THE LETTER OF TRANSMITTAL IS FURNISHED TO YOU FOR YOUR
INFORMATION ONLY AND CANNOT BE USED BY YOU TO TENDER SHARES HELD BY US FOR YOUR
ACCOUNT.

  Accordingly, we request instructions as to whether you wish to have us tender
on your behalf any or all Shares held by us for your account pursuant to the
terms and conditions set forth in the Offer.
 
  Please note the following:
 
    1. The tender price is $64.00 per Share net to you in cash without
  interest thereon, upon the terms and subject to the conditions set forth in
  the Offer.
 
    2. The Offer is being made for all outstanding Shares.
 
    3. The Offer is conditioned upon, among other things, Shares representing
  at least a majority of the total number of outstanding Shares on a fully-
  diluted basis (assuming the exercise of all outstanding options) being
  validly tendered and not withdrawn prior to the expiration of the Offer.
  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.
 
    4. Tendering stockholders will not be obligated to pay brokerage fees or
  commissions or, except as otherwise provided in Instruction 6 of the Letter
  of Transmittal, stock transfer taxes on the purchase of Shares by the
  Purchaser pursuant to the Offer.
 
    5. The Offer and withdrawal rights will expire at 12:00 midnight, New
  York City time, on Friday, April 28, 1995, unless the Offer is extended.
 
    6. Payment for Shares purchased pursuant to the Offer will in all cases
  be made only after timely receipt by The First National Bank of Boston (the
  "Depositary") of (a) Share Certificates or timely confirmation of the book-
  entry transfer of such Shares into the account maintained by the Depositary
  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, (b) the Letter of Transmittal (or a facsimile
  thereof), properly completed and duly executed, with any required signature
  guarantees or an Agent's Message (as defined in the Offer to Purchase), in
  connection with a book-entry delivery, and (c) any other documents required
  by the Letter of Transmittal. Accordingly, payment may not be made to all
  tendering stockholders at the same time depending upon when certificates
  for or confirmations of book-entry transfer of such Shares 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 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 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 Bear, Stearns & 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.

imprisonment.

                                                           FOR IMMEDIATE RELEASE

                   RAYTHEON AND E-SYSTEMS COMBINE IN MERGER
                            VALUED AT $2.3 BILLION

               Raytheon Launches Cash Tender Offer For E-Systems

              Creates Company With Over $12 Billion In Revenues

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

     Lexington, Massachusetts/Dallas, Texas, April 3, 1995 - The boards of 
directors of RAYTHEON Company (NYSE:RTN) and E-Systems, Inc. (NYSE:ESY) said 
today that they have entered into a definitive agreement to combine the two 
companies and have unanimously approved a fully financed $64 per share cash 
offer by Raytheon for E-Systems outstanding shares. The merger creates a company
with over $12 billion in annualized revenues in a transaction that is expected 
to provide a small increase in Raytheon's earnings per share in 1995 and an 
increasingly positive contribution to earnings per share thereafter.

     The transaction, valued at approximately $2.3 billion, will be effected 
through a cash tender offer that commenced today. The offer is subject to the 
receipt of a majority of the E-Systems common shares outstanding and 
Hart-Scott-Rodino antitrust review. Unless otherwise extended, the tender offer 
is expected to close at midnight on April 28, 1995.

     Raytheon has received financing commitments from Chemical Bank, Bank of 
America National Trust and Savings Association and The Chase Manhattan Bank to 
provide up to $3 billion in the aggregate in unsecured financing to support the 
tender offer.

     Dennis J. Picard, Raytheon Chairman and Chief Executive Officer, said, "We 
are very fortunate to be combining with such a successful growing company in 
the defense and government electronics business. The merger of E-Systems and 
Raytheon is consistent with our strategy to remain a strong diversified 
commercial company and a top tier player in defense. The combination opens new 
defense and commercial markets worldwide, brings our annualized electronics 
sales to $6 billion and our current electronics backlog to $8 billion. Even 
after the merger with E-Systems, over 50 percent of Raytheon's revenues will be 
commercial, and we remain committed to growing our commercial businesses. 
Despite the added debt due to the merger, our strong balance sheet and cash flow
will provide us with the flexibility to make future acquisitions in our 
commercial and defense businesses.

     "Raytheon and E-Systems have complementary capabilities and cultures. Our
two companies share a common set of values, high integrity, and strong
determination to deliver high-quality products and services to our customers. We
look forward to welcoming the E-Systems employees to the Raytheon family," Mr.
Picard added.

     Lowell Lawson, who will remain Chairman and Chief Executive Officer of 
E-Systems and will join Raytheon as an Executive Vice President and a member of 
its board of directors, said, "Our board and management team have endorsed the 
combination of E-Systems and Raytheon in order to provide our stockholders, 
employees, communities, customers and programs with the support necessary to 
continue to grow and prosper within the global defense electronics industry. 
Raytheon shares the values that we hold important and has made significant 
strides in transferring its defense technologies to non-defense areas just as we
have. We are pleased that E-Systems, which will become a wholly-owned subsidiary
of Raytheon, will continue to be headquartered in Dallas, Texas and will operate
under the E-Systems name. The E-Systems board will become an advisory board with
both E-Systems and Raytheon members.

     "Raytheon will help support our efforts to effectively serve our unique 
customers, guarantee our position as a leader in the defense and government 
electronics business and continue our long-standing strategy of expanding our 
defense technologies into commercial markets. E-Systems businesses continue to 
find a strong customer base both within and beyond the defense electronics 
industry. Raytheon gives us an enhanced position for accomplishing our business 
objectives," Mr. Lawson concluded.

     Bear, Stearns & Co. Inc. is financial advisor to Raytheon and dealer 
manager for the tender offer. The tender offer will be made only pursuant to 
definitive offering documents to be filed with the Securities and Exchange 
Commission.

     E-Systems, headquartered in Dallas, Texas with 1994 sales of approximately 
$2.0 billion, had a record year-end backlog in excess of $2.6 billion. The 
Company's largest business segments include the design, development and 
production of reconnaissance and surveillance systems and command, control and 
communications for the U.S. government. In addition, the Company has significant
business in the areas of mass storage, electronic imaging and other 
information-based technologies. The Company has approximately 16,000 employees.

entry transfer of such Shares 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 Letter
of Transmittal delivered with the Offer to Purchase (or a facsimile thereof),
properly completed and duly executed, with any required signature guarantees or
an Agent's Message (as defined in the Offer to Purchase) in connection with a
book-entry transfer of Shares and (iii) any other documents required by the
Letter of Transmittal.
 
  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 existence of any of the conditions specified in
Section 14 of the Offer to Purchase, by giving oral or written notice of such
extension to the Depositary. Any such extension will be followed as promptly as
practicable by public announcement thereof, and such announcement 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 (as defined below).
 
                                       2

  Tenders of Shares made pursuant to the Offer are irrevocable, except that
Shares 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 June 1, 1995
(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, April
28,1995, unless and until the Purchaser, subject to the terms of the Merger
Agreement, shall have further 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. 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 to be
withdrawn, the number of Shares to be withdrawn, and (if Share Certificates
have been tendered) the name of the registered holder of the Shares as set
forth in the Share Certificate, if different from that of the person who
tendered such Shares. If Share 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 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 tendered for
the account of an Eligible Institution. If Shares 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 Shares, 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
properly withdrawn will be deemed not validly tendered for purposes of the
Offer, but may be tendered 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, is contained in the Offer to Purchase, and is incorporated herein by
reference.
 
  The Company is providing the Purchaser with the Company's stockholder list
and security position listings for the purpose of disseminating the Offer to
holders of Shares. The Offer to Purchase and the related Letter of Transmittal
and, if required, other relevant materials will be mailed to record holders of
Shares 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 or who are listed as participants in a clearing
agency's security position listing for subsequent transmittal to beneficial
owners of Shares.
 
  THE OFFER TO PURCHASE AND THE RELATED LETTER OF TRANSMITTAL CONTAIN IMPORTANT
INFORMATION WHICH SHOULD BE READ CAREFULLY BEFORE ANY DECISION IS MADE WITH
RESPECT TO THE OFFER.

Ladies and Gentlemen:

          We understand that Raytheon Company ("Raytheon") proposes to
acquire all the issued and outstanding shares (the "Shares") of common stock of
E-Systems, Inc., a Delaware corporation ("E-Systems"), pursuant to a merger
agreement to be entered into on a friendly basis between Raytheon and E-Systems
(the "Merger Agreement").  The Merger Agreement will provide for an all cash
tender offer by Raytheon or a wholly owned subsidiary of Raytheon (the "Tender
Offer") followed by a merger for any remaining shares (the "Merger"; the Tender
Offer and the Merger being collectively called the "Acquisition").  You have
advised us that in order to finance the Acquisition you will require a
revolving credit/competitive advance facility in an aggregate principal amount
of $3,000,000,000 (the "Facility").  In addition, the Facility may be used
following the Merger to provide working capital and for other general corporate
purposes of Raytheon, including commercial paper backup.

                                                                               2



          Each of Chemical Bank, Bank of America National Trust and Savings
Association and The Chase Manhattan Bank, N.A. (each a "Managing Agent" and,
collectively, the "Managing Agents") is pleased to advise you of its several
commitment to provide $1,000,000,000 of the Facility, upon the terms and
subject to the conditions set forth or referred to herein and in the Summary of
Terms and Conditions attached as Exhibit A hereto (the "Term Sheet").  

          Raytheon hereby engages (a) Chemical Securities Inc. to act as the
arranger and financial advisor (the "Arranger") for the Facility and (b) Chase
Securities, Inc. to act as the syndication agent (the "Syndication Agent") for
the Facility.  In addition, Raytheon hereby engages (a) Chemical Bank to act as
administrative agent (the "Administrative Agent") for the Facility and (b) BA
Securities, Inc. to act as documentation agent (the "Documentation Agent" and,
together with the Arranger, the Syndication Agent and the Administrative Agent,
the "Agents") for the Facility.  Each Agent hereby accepts such engagement and
shall endeavor, with the assistance of Raytheon, to structure, document and
arrange the Facility and to assemble a syndicate of financial institutions
satisfactory to Raytheon and the Managing Agents to provide the Facility.  It
is understood and agreed that the appointment of any co-agents for the Facility
would be subject to the approval of Raytheon and the Managing Agents.

          Each Managing Agent reserves the right, prior to or after the
execution of definitive documentation with respect to the Facility, to
syndicate all or part of its commitment to one or more financial institutions
reasonably acceptable to Raytheon which will become parties to the definitive
credit documentation (such institutions, together with the Managing Agents, the
"Lenders").  No proposed Lender will receive compensation outside the terms
contained herein, in the Term Sheet and in the Fee Letters referred to below in
order to obtain its commitment to participate in the Facility.  You agree to
provide such assistance in the syndication effort as may be reasonably
requested, including through your existing lending relationships, by making
members of management of Raytheon and its subsidiaries available to meet with
prospective syndicate members and by assisting the Managing Agents in the
preparation of a financing memorandum and other marketing materials.

          You agree to provide the Agents with all information reasonably
requested by them in connection with

                                                                               3


the arrangement of the Facility. You represent and covenant that (a) all
information (other than the financial projections referred to below and, with
respect to E-Systems, subject to the limitations on disclosure of classified
information) concerning Raytheon, its subsidiaries, the transactions
contemplated hereby and, to the best of your knowledge, E-Systems, made
available to any Agent or Managing Agent by you or your authorized
representatives is or will be complete and correct in all material respects and
does not and will not contain any untrue statement of a material fact or omit to
state a material fact necessary in order to make the statements contained
therein not materially misleading in light of the circumstances under which such
statements are made and (b) all financial projections prepared by you or your
authorized representatives and made available to any Agent or Managing Agent
have been or will be prepared in good faith based upon reasonable assumptions.

          As consideration for the agreements of the Managing Agents and the
Agents hereunder, you agree to pay the fees provided for in each of the Fee
Letters dated the date hereof and delivered herewith between you and each
Managing Agent (the "Fee Letters") at the times provided therein.  Once paid,
such fees shall not be refundable under any circumstances.

          The agreements of the Agents and the Managing Agents and the
Managing Agents' several commitments hereunder are subject to (a) the
satisfaction of each Managing Agent with the structure and terms of the
Acquisition, with all legal, tax and accounting matters relating to the
Acquisition and with the terms of the Merger Agreement and all other agreements
to be entered into in connection therewith; (b) the absence of any material
adverse change since December 31, 1994, in the business, assets, condition
(financial or otherwise) or prospects of Raytheon and its subsidiaries and
E-Systems and its subsidiaries, taken as a whole; (c) the negotiation,
execution and delivery of definitive credit documentation satisfactory to the
Managing Agents and their counsel; (d) there not having occurred and being
continuing an adverse change in financial, banking or capital market conditions
since the date hereof that, in the Agents' reasonable judgment, would have a
material adverse effect on the syndication of the Facility; and (e) the Agents'
satisfaction that, following the date hereof and during the syndication of the
Facility, Raytheon and its subsidiaries

                                                                               4


shall not have offered, placed or arranged or be in the process of offering,
placing or arranging any competing issues of debt securities (other than
commercial paper) or competing bank credit facilities of Raytheon or its
subsidiaries.

          You agree to indemnify and hold harmless each Agent, each Managing
Agent and their respective officers, directors, employees, agents and
affiliates from and against any and all losses, claims, damages, liabilities
and expenses arising out of or in connection with this letter agreement, the
Acquisition or the transactions contemplated hereby or thereby or any claim,
litigation, investigation or proceeding relating to any of the foregoing,
regardless of whether any of such indemnified parties is a party thereto, and
to reimburse each of such indemnified parties upon demand for any legal or
other expenses incurred in connection with investigating or defending any of
the foregoing, except to the extent such losses, claims, damages, liabilities
or expenses result from the willful misconduct or gross negligence of the party
seeking indemnification.  You also agree to reimburse each Agent and each
Managing Agent for all reasonable out-of-pocket expenses (including, without
limitation, expenses of due diligence, syndication expenses and reasonable
fees, disbursements and other charges of counsel) incurred in connection with
the Facility and the preparation of this letter agreement, the Term Sheet, the
Fee Letters and the definitive documentation for the Facility.  The provisions
contained in this paragraph shall remain in full force and effect regardless of
whether definitive financing documentation shall be executed and delivered and
notwithstanding the termination of this letter agreement or the several
commitments of the Managing Agents hereunder.

          If the foregoing correctly sets forth our agreement, please
indicate your acceptance of the terms hereof and of the Term Sheet and the Fee
Letters by signing in the appropriate space below and in the Fee Letters and
returning to each Managing Agent the enclosed duplicate originals of this
letter agreement and such Managing Agent's Fee Letter, not later that 5:00
p.m., New York City time, on April 5, 1995.  The several commitments of the
Managing Agents hereunder will expire at such time in the event the Managing
Agents have not received such executed originals in accordance with the
immediately preceding sentence.  In the event that the initial borrowing under
the Facility shall not have occurred on or before June 30, 1995, then this

letter agreement and the commitments and obligations contained herein shall in
any event terminate, unless each party hereto shall agree to an extension.  The
compensation, reimbursement and indemnification provision contained herein and
in the Fee Letters shall survive any termination hereof.

          This letter agreement shall not be assignable by you without the
prior written consent of each Managing Agent, and may not be amended or waived
except by an instrument in writing signed by you, each Agent and each Managing
Agent.  This letter agreement may be executed in any number of counterparts,
each of which shall be an original and all of which, when taken together, shall
constitute one agreement.  Delivery of an executed counterpart of a signature
page of this letter agreement shall be effective as delivery of a manually
executed counterpart of this letter agreement.  This letter agreement is
intended to be solely for the benefit of the parties hereto and is not intended
to confer any benefits upon, or create any rights in favor of, any person other
than the parties hereto.  This letter agreement shall be governed by, and
construed in accordance with, the laws of the State of New York.

                            CAF Procedures
                            --------------

          Acting as Administrative Agent, Chemical Bank ("Chemical") will
manage the CAF, whereby the Lenders may bid on short term loans to the Borrower
on an uncommitted basis.  Each Lender may bid up to the full amount of the
requested borrowing regardless of its individual commitment amount under the
Facility.  All communications pursuant to the CAF shall be in writing and
according to predetermined formats as set forth in the definitive credit
agreement.

          CAF advances, regardless of which Lender or Lenders provide them,
will be deemed to utilize the commitments of all Lenders pro rata in accordance
with their respective shares for purposes of determining (a) the aggregate
remaining availability under the Facility and (b) the remaining availability of
each Lender under the Facility.

          To access the CAF (i.e., request an auction), the Borrower will
provide notice to Chemical describing its borrowing request with regard to
amount, value date, maturity date, and type of borrowing.  

          In accordance with a predetermined schedule, Chemical will relay
to the Lenders the information contained in the borrowing request.  Each
Lender, in its sole discretion, may bid on these borrowings.  To evidence its
bid each Lender will submit its bid to Chemical stating the amount, interest
rate and other information as required.  Chemical will submit its bid directly
to the Borrower at a mutually agreeable time in advance of its receipt of bids
of the other Lenders.  Bids not submitted in the format required, or according
to the schedule as determined, will be rejected in Chemical's discretion.

          Chemical will arrange the bids in ascending yield order and relay
them to the Borrower, who will be required, by a predetermined time, either (a)
to cancel the borrowing request or (b) to award the mandate(s) on the basis of
yield.  The Borrower will inform Chemical of the winning bid(s) and Chemical
will then inform the successful Lender(s).

          The advances made in each auction will be under one of the following
options:

          LIBOR Auction Advance
          Fixed Rate Auction Advance

         and the Purchaser further agree to take all steps necessary to
         cause the Offer Documents as so corrected to be filed with the
         SEC and to be disseminated to stockholders of the Company, in
         each case as and to the extent required by applicable federal
         securities laws.  The Company and its counsel shall be given a
         reasonable opportunity to review and comment upon any Offer
         Documents to be filed with the SEC prior to any such filing.

         isfied or earlier waived.  If at the expiration date of the
         Offer, the conditions to the Offer described in Annex I hereto

                                  ---------------
         hereby approves of and consents to the Offer and represents
         that (i) the Board, at a meeting duly called and held, has, in

         have each rendered to the Board their opinion that the per
         share consideration to be received by the stockholders of the
         Company pursuant to the Offer and the Merger is fair to such
         stockholders from a financial point of view.

                   (b)  The Company hereby agrees promptly to prepare
         and, after affording the Purchaser a reasonable opportunity to

         its stockholders, a Solicitation/Recommendation Statement on

         amendments or supplements thereto, the "Schedule 14D-9") con-

         Board deems it necessary to do so in the exercise of its fidu-
         ciary and other legal obligations after consultation with out-
         side counsel.  Each of the Company, on the one hand, and Parent
         and the Purchaser, on the other hand, agree promptly to correct
         any information provided by either of them for use in the
         Schedule 14D-9 if and to the extent that it shall have become
         false or misleading in any material respect, and the Company
         further agrees to take all steps necessary to cause the Sched-
         ule 14D-9 as so corrected to be filed with the SEC and to be
         disseminated to the stockholders of the Company, in each case
         as and to the extent required by applicable federal securities
         laws.  

                   (c)  In connection with the Offer, the Company will
         furnish the Purchaser with such information (which will be
         treated and held in confidence by the Purchaser in accordance
         with the terms of the Confidentiality Agreement (as hereinafter
         defined)) and assistance as the Purchaser or its agents or rep-
         resentatives may reasonably request in connection with the
         preparation of the Offer and communicating the Offer to the
         record and beneficial holders of the Shares.

         designees to the Board shall be subject to Section 14(f) of the
         Exchange Act and Rule 14f-1 thereunder, if applicable.  The
         Company shall promptly take all actions required pursuant to
         such Section and Rule in order to fulfill its obligations under
         this Section 1.03 and shall include in the Schedule 14D-9 such

         ent's designees pursuant to this Section 1.03 and prior to the
         Effective Time (as hereinafter defined), any amendment or ter-
         mination of this Agreement by the Company or the Board, any
         extension by the Company or the Board, of the time for the
         performance of any of the obligations or other acts of Parent
         or the Purchaser or waiver of any of the Company's rights
         hereunder, will require the concurrence of, and shall be ef-

         ommendation of (x) directors who were directors on the date
         hereof or (y) the Continuing Directors (the persons referred to
         in clauses (i) and (ii) being the "Continuing Directors"), even

         Effective Time, the Board shall include three Continuing
         Directors (subject to their availability and willingness to
         serve).

         ing the Control Date, the Company shall maintain an Advisory
         Board for the purpose of consulting on matters related to the
         business of the Company.  The members of the Advisory Board
         shall be chosen by mutual agreement of the Chief Executive
         Officer of the Company and the Chief Executive Officer of Par-
         ent from among the individuals who constitute the Board on the
         date hereof, including any of the Continuing Directors, and
         representatives of Parent.  Parent shall provide or cause the
         Company to provide compensation and benefits to the members of
         the Advisory Board that, in the aggregate, are no less favor-
         able than those provided to the Company's directors as of the
         date hereof.  Purchaser agrees that it will pay, or will cause
         the Surviving Corporation to pay, in accordance with the terms

         product of (A) the excess, if any, of the Merger Price over the
         exercise price thereof and (B) the number of Shares subject
         thereto (such payment to be net of applicable withholding
         taxes); provided that the foregoing shall not require any ac-
         tion which violates the Option Plans; provided, further, that
         if it is determined that compliance with any of the foregoing
         would cause any individual subject to Section 16 of the Ex-
         change Act to become subject to the profit recovery provisions
         thereof, any Options held by such individual will be cancelled
         or purchased, as the case may be, as promptly thereafter as
         possible so as not to subject such individual to any liability
         pursuant to Section 16, and such individual will be entitled to
         receive from the Company or the Surviving Corporation at the
         Effective Time or as soon as practicable thereafter (or, if
         later, the date six months and one day following the grant of
         such option), for each Share subject to an Option, an amount
         equal to the excess, if any, of the Merger Price over the per
         Share exercise price of such Option.  

                   (b)  Except as provided herein or as otherwise agreed
         to by the parties and to the extent permitted by the Option
         Plans, (i) the Option Plans shall terminate as of the Effective
         Time and the provisions in any other plan, program or arrange-
         ment, providing for the issuance or grant by the Company or any
         of its subsidiaries of any interest in respect of the capital
         stock of the Company or any of its subsidiaries (other than the
         EMASS Option Plan (as hereinafter defined)) shall be deleted as
         of the Effective Time and (ii) the Company shall use all rea-
         sonable efforts to ensure that following the Effective Time no
         holder of Options or any participant in the Option Plans or any
         other such plans, programs or arrangements (other than the
         EMASS Option Plan) shall have any right thereunder to acquire

                                      -8-

         any equity securities of the Company, the Surviving Corporation
         or any subsidiary thereof.

                   (c)  The Company shall take all actions to provide
         that each share of restricted stock granted under the Option
         Plans shall become fully vested and free of restrictions im-
         mediately prior to the consummation of the Offer and that any
         holder of a restricted stock grant may elect to authorize the
         Company to retain a number of Shares from such grant having an
         aggregate value (based upon $64.00 per Share) equal to the sum
         of (i) the aggregate purchase price for such Shares under the
         applicable Option Plan and (ii) any withholding taxes appli-
         cable to the vesting of such grant, in lieu of the payment of
         such amount in cash.

                                  ---------------------
         quired by applicable law in order to consummate the Merger, the
         Company, acting through the Board, shall, in accordance with
         applicable law:

              special meeting of its stockholders (the "Special Meet-
              ing") as soon as practicable following the purchase of and
              payment for Shares by the Purchaser pursuant to the Offer
              for the purpose of considering and adopting this Agreement
              and such other matters as may be necessary to consummate
              the transactions contemplated herein;

                  (ii)  prepare and file with the SEC a preliminary
              proxy statement relating to the matters to be considered
              at the Special Meeting pursuant to this Agreement and use
              its reasonable best efforts (x) to obtain and furnish the
              information required to be included by the SEC in the
              Proxy Statement (as hereinafter defined) and, after con-
              sultation with Parent, to respond promptly to any comments
              made by the SEC with respect to the preliminary proxy
              statement and to cause a definitive proxy statement (the
              "Proxy Statement") to be mailed to its stockholders and
              (y) subject to the fiduciary obligations of the Board un-
              der applicable law, to obtain the necessary approval and
              adoption of this Agreement and such other matters as may
              be necessary to consummate the transactions contemplated
              hereby by its stockholders; and

                 (iii)  subject to the fiduciary obligations of the
              Board under applicable law after consultation with outside
              counsel, include in the Proxy Statement the recommendation

              of the Board that stockholders of the Company vote in fa-
              vor of the adoption of this Agreement and such other mat-
              ters as may be necessary to consummate the transactions
              contemplated hereby.

                   (b)  Parent agrees that it will vote, or cause to be
         voted, all of the Shares then owned by it, the Purchaser or any
         of its other subsidiaries in favor of the approval and adoption
         of this Agreement and such other matters as may be necessary to

         ers.  Notwithstanding Section 3.03 hereof, in the event that
         ---
         Parent, the Purchaser or any other subsidiary of Parent shall
         acquire at least 90% of the outstanding Shares pursuant to the
         Offer or otherwise, the parties hereto agree, at the request of
         Parent or the Purchaser, to take all necessary and appropriate
         action to cause the Merger to become effective as soon as
         practicable after the acceptance for payment and purchase of
         Shares by the Purchaser pursuant to the Offer without a meeting
         of stockholders of the Company in accordance with Section 253
         of the DGCL.

                   Section 3.05.  Consummation of the Merger.  As soon
                                  --------------------------
         as practicable after the satisfaction or waiver of the condi-
         tions set forth in Article VIII hereof, the Surviving Corpora-
         tion shall execute in the manner required by the DGCL and file
         with the Delaware Secretary of State the Certificate of Merger
         (or, in the event Section 3.04 hereof is applicable, the Pur-
         chaser shall execute in the manner required by the DGCL and
         file with the Delaware Secretary of State a certificate of
         ownership and merger), and the parties shall take such other
         and further actions as may be required by law to make the
         Merger effective as promptly as is practicable.


                                    ARTICLE IV

                      DISSENTING SHARES; PAYMENT FOR SHARES

                   Section 4.01.  Dissenting Shares.  Notwithstanding
                                  -----------------
         anything in this Agreement to the contrary, Shares outstanding
         immediately prior to the Effective Time and held by a holder
         who has not voted in favor of the Merger or consented thereto
         in writing and who has demanded appraisal for such Shares in
         accordance with Section 262 of the DGCL, if such Section 262
         provides for appraisal rights for such Shares in the Merger
         ("Dissenting Shares"), shall not be converted into the right to
         receive the Merger Price, as provided in Section 3.01 hereof,
         unless and until such holder fails to perfect or withdraws or

                                     -10-
<PAGE>
 
         otherwise loses his right to appraisal and payment under the
         DGCL.  If, after the Effective Time, any such holder fails to
         perfect or withdraws or loses his right to appraisal, such
         Dissenting Shares shall thereupon be treated as if they had
         been converted as of the Effective Time into the right to re-
         ceive the Merger Price to which such holder is entitled, with-
         out interest or dividends thereon.  The Company shall give
         Parent prompt notice of any demands received by the Company for
         appraisal of Shares and Parent shall have the right to partic-
         ipate in all negotiations and proceedings with respect to such
         demands.  The Company shall not, except with the prior written
         consent of Parent, make any payment with respect to, or settle
         or offer to settle, any such demands.

                   Section 4.02.  Payment for Shares.  (a)  From and
                                  ------------------
         after the Effective Time, a bank or trust company to be desig-
         nated by Parent (and reasonably acceptable to the Company)
         shall act as paying agent (the "Paying Agent") in effecting the
         payment of the Merger Price for certificates (the "Certifi-
         cates") formerly representing Shares and entitled to payment of
         the Merger Price pursuant to Section 3.01 hereof.  At the Ef-
         fective Time, Parent or the Purchaser shall deposit, or cause
         to be deposited, in trust with the Paying Agent for the benefit
         of holders of Shares the aggregate Merger Price to which hold-
         ers of Shares shall be entitled at the Effective Time pursuant
         to Section 3.01 hereof.

                   (b)  Promptly after the Effective Time, Parent shall
         cause the Paying Agent to mail to each record holder of Cer-
         tificates that immediately prior to the Effective Time repre-
         sented Shares (other than Certificates representing Shares held
         by Parent or the Purchaser, any subsidiary of Parent or the
         Purchaser or in the treasury of the Company) a form of letter
         of transmittal which shall specify that delivery shall be ef-
         fected, and risk of loss and title to the Certificates shall
         pass, only upon proper delivery of the Certificates to the
         Paying Agent and instructions for use in surrendering such
         Certificates and receiving the Merger Price therefor.  Upon the
         surrender of each such Certificate, the Paying Agent shall pay
         the holder of such Certificate in exchange therefor cash in an
         amount equal to the Merger Price multiplied by the number of
         Shares formerly represented by such Certificate, and such Cer-
         tificate shall forthwith be cancelled.  Until so surrendered,
         each such Certificate (other than Certificates representing
         Dissenting Shares and Certificates representing Shares held by
         Parent or the Purchaser, any subsidiary of Parent or the Pur-
         chaser or in the treasury of the Company) shall represent
         solely the right to receive the aggregate Merger Price relating
         thereto.  No interest shall be paid or accrued on such Merger
         Price.

                                     -11-
<PAGE>
 
                   (c)  Promptly following the date which is nine months
         after the Effective Time, the Paying Agent shall deliver to
         Parent all cash, Certificates and other documents in its pos-
         session relating to the transactions described in this Agree-
         ment, and the Paying Agent's duties shall terminate.  Thereaf-
         ter, each holder of a Certificate formerly representing a Share
         (other than Certificates representing Dissenting Shares and
         Certificates representing Shares held by Parent or the Pur-
         chaser, any subsidiary of Parent or the Purchaser or in the
         treasury of the Company) may surrender such Certificate to
         Parent and (subject to applicable abandoned property, escheat
         and similar laws) receive in consideration therefor the ag-
         gregate Merger Price relating thereto, without any interest or
         dividends thereon.

                   (d)  The Merger Price shall be net to each holder of
         Certificates in cash, subject to reduction only for any appli-
         cable federal back-up withholding or, as set forth in Section
         4.02(e), stock transfer taxes payable by such holder.

                   (e)  If payment of cash in respect of any Certificate
         is to be made to a person other than the person in whose name
         such Certificate is registered, it shall be a condition to such
         payment that the Certificate so surrendered shall be properly
         endorsed or shall be otherwise in proper form for transfer and
         that the person requesting such payment shall have paid any
         transfer and other taxes required by reason of such payment in
         a name other than that of the registered holder of the Certif-
         icate surrendered or shall have established to the satisfaction
         of Parent or the Paying Agent that such tax either has been
         paid or is not payable.

                   (f)  After the Effective Time, there shall be no
         transfers on the stock transfer books of the Surviving Corpo-
         ration of any Shares which were outstanding immediately prior
         to the Effective Time.  If, after the Effective Time, Certifi-
         cates formerly representing Shares (other than Certificates
         representing Shares held by Parent or the Purchaser, any sub-
         sidiary of Parent or the Purchaser or in the treasury of the
         Company) are presented to Parent, the Surviving Corporation or
         the Paying Agent, they shall be surrendered and cancelled in
         return for the payment of the aggregate Merger Price relating
         thereto, without interest, as provided in this Article IV,
         subject to applicable law in the case of Dissenting Shares.

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

                   The Company represents and warrants to Parent and the
         Purchaser as follows:

                   Section 5.01.  Organization.  The Company and each of
                                  ------------
         its Significant Subsidiaries (as defined below) is a corpora-
         tion duly organized, validly existing and in good standing un-
         der the laws of their respective jurisdictions of incorporation
         and the Company and each of its Significant Subsidiaries has
         all requisite corporate power and authority to own, lease and
         operate their respective properties and to carry on their re-
         spective businesses as now being conducted.  The Company and
         each of its subsidiaries is duly qualified or licensed and in
         good standing to do business in each jurisdiction in which the
         property owned, leased or operated by it or the nature of the
         business conducted by it makes such qualification necessary,
         except in such jurisdictions where the failure to be so duly
         qualified or licensed and in good standing would not, individ-
         ually or in the aggregate, have a material adverse effect on
         the business, operations, assets, financial condition or re-
         sults of operations of the Company and its subsidiaries taken
         as a whole (a "Company Material Adverse Effect").  The Company
         owns directly all of the outstanding capital stock of each of
         its Significant Subsidiaries.  As used in this Agreement a
         "Significant Subsidiary" means a corporation which is a "sig-
         nificant subsidiary" within the meaning of Rule 1-02(w) of
         Regulation S-X.

                   Section 5.02.  Capitalization.  The authorized capi-
                                  --------------
         tal stock of the Company consists of 50,000,000 Shares and
         185,000 shares of preferred stock, par value $20.00 per share
         ("Company Preferred Stock").  As of March 30, 1995, there were
         34,173,453 Shares and no shares of Company Preferred Stock is-
         sued and outstanding, and there are no Shares or shares of
         Company Preferred Stock held in the Company's treasury.  As of
         the date hereof, there were outstanding options to purchase
         2,391,703 Shares under the Option Plans.  Except for the Rights
         granted pursuant to the Rights Agreement (which shall be re-
         deemed pursuant to Section 7.10 hereof), Options under the Op-
         tion Plans (which shall be cancelled pursuant to Section
         3.02(a) hereof), options outstanding to purchase not more than
         920,000 shares of common stock of the Company's subsidiary,
         EMASS, Inc. ("EMASS") pursuant to the EMASS 1994 Employee Stock
         Option Plan (the "EMASS Option Plan") (which options will
         become fully vested upon consummation of the Offer and remain
         outstanding after the Effective Time), and additional options
         to purchase up to 150,000 shares of EMASS common stock which

                                     -13-

         may be granted at the Company's or EMASS's discretion prior to
         the Control Date, there were not as of the date hereof, and at
         all times thereafter through the Control Date there will not
         be, any existing options, warrants, calls, subscriptions, or
         other rights or other agreements or commitments obligating the
         Company or any of its subsidiaries to issue, transfer or sell
         any shares of capital stock of the Company or any of its sub-
         sidiaries or any other securities convertible into or evidenc-
         ing the right to subscribe for any such shares.  All issued and
         outstanding Shares are duly authorized and validly issued,
         fully paid, non-assessable and free of preemptive rights with
         respect thereto.

                   Section 5.03.  Authority.  The Company has full cor-
                                  ---------

         ment and, subject to the approval of its stockholders, if re-
         quired, to consummate the transactions contemplated hereby.

         tion of the transactions contemplated hereby have been duly and
         validly authorized and approved by the Board, and other than
         the approval by its stockholders, if required, no other corpo-
         rate proceedings are necessary to authorize this Agreement or
         the consummation of the transactions contemplated hereby.  This
         Agreement has been duly and validly executed and delivered by
         the Company and, assuming this Agreement constitutes a legal,
         valid and binding agreement of the other parties hereto, it
         constitutes a legal, valid and binding agreement of the Com-
         pany, enforceable against it in accordance with its terms.

                   Section 5.04.  No Violations; Consents and Approvals.
                                  -------------------------------------
         (a)  Neither the execution and delivery of this Agreement nor
         the consummation of the transactions contemplated hereby nor
         compliance by the Company with any of the provisions hereof
         will (i) violate any provision of its certificate of incorpo-
         ration or by-laws, (ii) result in a violation or breach of, or
         constitute (with or without due notice or lapse of time or

         the United States or which, either individually or in the ag-
         gregate, would not have a Company Material Adverse Effect or
         materially impair the Company's ability to consummate the
         transactions contemplated hereby or for which the Company has
         received or, prior to the consummation of the Offer, shall have
         received appropriate consents or waivers.

                   (b)  No filing or registration with, notification to,

         (a)  The Company has made available to Parent and the Purchaser
         copies of each registration statement, report, proxy statement,

         their respective dates, the Company's SEC Documents complied in
         all material respects with the applicable requirements of the
         Securities Act of 1933, as amended, and the Exchange Act, as
         the case may be, and none of such SEC Documents contained any
         untrue statement of a material fact or omitted to state a mate-
         rial fact required to be stated therein or necessary to make
         the statements therein, in light of the circumstances under
         which they were made, not misleading.

                   (b)  As of their respective dates, the consolidated
         financial statements of the Company included in the Company's
         Reports on Form 10-K and Reports on Form 10-Q included in the
         SEC Documents were prepared in accordance with generally ac-
         cepted accounting principles applied on a consistent basis
         during the periods involved (except as may be indicated therein
         or in the notes thereto) and fairly presented the Company's
         consolidated financial position and that of its consolidated
         subsidiaries as at the dates thereof and the consolidated re-
         sults of their operations and statements of cash flows for the
         periods then ended (subject, in the case of unaudited state-
         ments, to the lack of footnotes thereto, to normal year-end
         audit adjustments and to any other adjustments described
         therein).

                                  -------------------------------------
         closed Liabilities.  (a)  Since December 31, 1994, except as
         ------------------
         disclosed in the SEC Documents filed prior to the date hereof,
         the Company has not (i) incurred any liability, whether or not
         accrued, contingent or otherwise, or suffered any event or oc-
         currence (other than events or occurrences which relate to
         general economic conditions or conditions generally affecting
         the defense industry) which, individually or in the aggregate,
         would have a Company Material Adverse Effect or (ii) made any
         changes in accounting methods, principles or practices or (iii)
         declared, set aside or paid any dividend or other distribution
         with respect to its capital stock, other than regular quarterly
         cash dividends at a rate not exceeding $.375 per Share per
         quarter, payable on the Company's customary dividend payment
         dates.  Since December 31, 1994 to the date of this Agreement,
         each of the Company and its subsidiaries has conducted its
         operations according to its ordinary course of business con-
         sistent with past practice.

                   (b)  Except as and to the extent disclosed by the
         Company in the SEC Documents, as of December 31, 1994, neither
         the Company nor any of its subsidiaries had any material
         liabilities or obligations of any nature, whether or not
         accrued, contingent or otherwise, that would be required by
         generally accepted accounting principles to be reflected on a
         consolidated balance sheet of the Company and its subsidiaries

         (including the notes thereto) or which would have, individually
         or in the aggregate, a Company Material Adverse Effect.

                   Section 5.07.  Litigation.  Except as disclosed by
                                  ----------
         the Company in the SEC documents, there is no suit, claim, ac-
         tion, proceeding or investigation pending or, to the knowledge
         of the Company, threatened against the Company or any of its
         subsidiaries or any of their respective properties or assets
         before any court or governmental entity with respect to which
         there is a reasonable likelihood of a determination which, in-
         dividually or in the aggregate, would have a Company Material
         Adverse Effect.  Except as disclosed by the Company in the SEC
         Documents, neither the Company nor any of its subsidiaries is
         subject to any outstanding order, writ, injunction or decree
         which, insofar as can be reasonably foreseen, individually or
         in the aggregate, in the future would have a Company Material
         Adverse Effect.  

                   Section 5.08.  Compliance with Applicable Law.  Ex-
                                  ------------------------------
         cept as disclosed by the Company in the SEC Documents, the
         Company and its subsidiaries hold all permits, licenses, vari-
         ances, exemptions, orders and approvals of all governmental
         entities necessary for the lawful conduct of their respective
         businesses (the "Company Permits"), except for failures to hold
         such permits, licenses, variances, exemptions, orders and ap-
         provals which would not, individually or in the aggregate, have
         a Company Material Adverse Effect.  Except as disclosed by the
         Company in the SEC Documents, the Company and its subsidiaries
         are in compliance with the terms of the Company Permits, except
         where the failure so to comply would not have a Company Mate-
         rial Adverse Effect.  Except as disclosed by the Company in the
         SEC Documents, the businesses of the Company and its subsid-
         iaries are not being conducted in violation of any law, ordi-
         nance or regulation of any governmental entity except for vio-
         lations or possible violations which individually or in the
         aggregate do not, and, insofar as reasonably can be foreseen,
         in the future will not, have a Company Material Adverse Effect.
         Except as disclosed by the Company in the SEC Documents, and
         except for the audit by the Internal Revenue Service of the
         Company's qualified benefit plans currently being conducted, no
         investigation or review by any governmental entity with respect
         to the Company or any of its subsidiaries is pending or, to the
         best knowledge of the Company, threatened nor, to the best
         knowledge of the Company, has any governmental entity indicated
         an intention to conduct the same, other than, in each case,
         those which the Company reasonably believes will not have a
         Company Material Adverse Effect.

                                  -----
         subsidiaries has filed, or caused to be filed, all federal,

         state, local and foreign income and other material tax returns
         required to be filed by it, has paid or withheld, or caused to
         be paid or withheld, all taxes of any nature whatsoever, with
         any related penalties, interest and liabilities (any of the
         foregoing being referred to herein as a "Tax"), that are shown
         on such tax returns as due and payable, or otherwise required
         to be paid, other than such Taxes as are being contested in
         good faith and for which adequate reserves have been estab-
         lished and other than where the failure to so file, pay or
         withhold would not have a Company Material Adverse Effect.
         There are no material claims or assessments pending against the
         Company or its subsidiaries for any alleged deficiency in any
         Tax, and the Company does not know of any threatened Tax claims
         or assessments against the Company or any of its subsidiaries
         which if upheld would have a Company Material Adverse Effect.
         None of the Company or any of its subsidiaries has made an
         election to be treated as a "consenting corporation" under
         Section 341(f) of the Internal Revenue Code of 1986, as amended
         (the "Code").  There is no material deferred inter-company gain
         within the meaning of the Treasury Regulations promulgated un-
         der Section 1502 of the Code.  There are no waivers or exten-
         sions of any applicable statute of limitations to assess any
         material Taxes.  Other than with respect to returns for the
         1994 taxable year, there are no outstanding requests for any
         extension of time within which to file any material return or
         within which to pay any material Taxes shown to be due on any
         return.

                                  ----------------------
         ployee benefit plan," as defined in Section 3(3) of the Em-
         ployee Retirement Income Security Act of 1974, as amended
         ("ERISA"), maintained by the Company or any of its subsidiaries
         (the "Plans") complies in all respects with all applicable re-
         quirements of ERISA (to the extent required to so comply) and
         the Code and other applicable laws, except where failure so to
         comply would not have a Company Material Adverse Effect.  No
         "reportable event" (as such term is defined in ERISA) or ter-
         mination has occurred with respect to any Plan under circum-
         stances which present a risk of liability to any governmental
         entity or other person which would have a Company Material
         Adverse Effect.  None of the Plans is a multiemployer plan, as
         such term is defined in ERISA.  Neither the Company and its
         subsidiaries, nor any of their respective directors, officers,
         employees or agents has, with respect to any Plan, engaged in
         any "prohibited transaction", as such term is defined in Sec-
         tion 4975 of the Code or Section 406 of ERISA, nor has any Plan
         engaged in any such prohibited transaction which could reason-
         ably be expected to result in any taxes or penalties or pro-
         hibited transactions under Section 4975 of the Code or under

         Section 502(i) of ERISA, which in the aggregate could reason-
         ably be expected to have a Company Material Adverse Effect.
         Copies of all of the Company's Plans covering United States
         employees of the Company and any related trusts and summary
         plan descriptions have been made available to the Purchaser.
         Except as specifically contemplated by this Agreement, or as
         provided in the SERP (as defined in Section 7.11), the Amended
         and Restated Indemnification Agreements between the Company and
         its directors and officers, the Option Plans or the EMASS
         Option Plan, neither the execution and delivery of this Agree-
         ment nor the consummation of the transactions contemplated
         hereby will result in, cause the accelerated vesting or deliv-
         ery of, or increase the amount or value of, any payment or
         benefit to any employee or former employee of the Company or
         any of its subsidiaries.

         all necessary action (i) to provide that neither Parent nor the
         Purchaser will become an "Acquiring Person," that no "Trigger-
         ing Event," "Stock Acquisition Date" or "Distribution Date" (as
         such terms are defined in the Rights Agreement) will occur and
         that Section 13 of the Rights Agreement will not be triggered,
         in each case as a result of the announcement, commencement or
         consummation of the Offer, the execution or delivery of this
         Agreement or any amendment hereto or the consummation of the
         transactions contemplated hereby and (ii) to redeem the Rights
         effective immediately prior to the Purchaser's acceptance of
         Shares for purchase pursuant to the Offer.

         inclusion or incorporation by reference in any such document.
         The Schedule 14D-9 and the Proxy Statement, if any, will comply
         as to form in all material respects with the provisions of the
         Exchange Act and the rules and regulations thereunder.  None of

                                    COVENANTS

                   Section 7.01.  Conduct of Business of the Company.
                                  ----------------------------------
         Except as contemplated by this Agreement or as expressly agreed
         to in writing by Parent, during the period from the date of
         this Agreement to the Control Date, each of the Company and its
         subsidiaries will conduct its operations according to its or-
         dinary course of business consistent with past practice, and
         will use commercially reasonable efforts to preserve intact its
         business organization, to keep available the services of its
         key employees and to maintain satisfactory relationships with
         suppliers, distributors, customers and others having material
         business relationships with it and will take no action not re-
         quired by law which would materially adversely affect the
         ability of the parties to consummate the transactions contem-
         plated by this Agreement or be materially inconsistent with
         such transactions.  The Company shall make such notifications
         to the U.S. Department of Defense and certain other classified
         customers of the Company as the Company determines are neces-
         sary to comply with the foregoing covenant.

                   Section 7.02.  Acquisitions and Divestitures.  Prior
                                  -----------------------------
         to the Control Date, the Company shall keep Parent advised of
         the status of all discussions and negotiations concerning pos-
         sible acquisitions and divestitures by the Company or any of
         its subsidiaries of any corporations or businesses, and the
         Company agrees that without the prior written consent of Parent
         it shall not make, or agree to make, any such acquisition or
         divestiture; provided that the foregoing restriction shall not
         apply to the transactions involving Asta and ATM previously
         disclosed by the Company to Parent.  Other acquisition or dis-
         position transactions will be determined by mutual agreement
         after consultation between the chief executive officers of
         Parent and the Company.

                   Section 7.03.  No Solicitation.  (a)  The Company
                                  ---------------
         agrees that, prior to the Effective Time, it shall not, and
         shall not authorize or permit any of its subsidiaries or any of
         its or its subsidiaries' directors, officers, employees, agents

                                     -23-

         or representatives, directly or indirectly, to solicit, ini-
         tiate, facilitate or encourage (including by way of furnishing
         or disclosing non-public information) any inquiries or the
         making of any proposal with respect to any merger, consolida-
         tion or other business combination involving the Company or its
         subsidiaries or acquisition of all or substantially all of the
         assets or capital stock of the Company and its subsidiaries
         taken as a whole (an "Acquisition Transaction") or negotiate,
         explore or otherwise engage in substantive discussions with any
         person (other than Parent, the Purchaser or their respective
         directors, officers, employees, agents and representatives)
         with respect to any Acquisition Transaction or enter into any
         agreement, arrangement or understanding requiring it to aban-
         don, terminate or fail to consummate the Merger or any other
         transactions contemplated by this Agreement; provided that the
         Company may, in response to an unsolicited written proposal
         with respect to an Acquisition Transaction from a third party,
         furnish information to, and negotiate, explore or otherwise
         engage in substantive discussions with such third party, and
         enter into any such agreement, arrangement or understanding, in
         each case only if the Board determines in good faith by a ma-
         jority vote, after consultation with its financial advisors and
         outside legal counsel of the Company, that failing to take such
         action would create a reasonable possibility of a breach of the
         fiduciary duties of the Board in connection with seeking an Ac-
         quisition Transaction that is more favorable to the stockhold-
         ers of the Company than the Offer and the Merger.  

                   (b)  The Company shall immediately advise Parent in
         writing of the receipt of any inquiries or proposals relating
         to an Acquisition Transaction and any actions taken pursuant to
         Section 7.03(a), unless the Board determines in good faith by a
         majority vote, after consultation with its outside legal
         counsel, that taking such action would create a reasonable
         possibility of a breach of the fiduciary duties of the Board in
         connection with seeking an Acquisition Transaction that is more
         favorable to the stockholders of the Company than the Offer and
         the Merger.

                   Section 7.04.  Access to Information.  From the date
                                  ---------------------
         of this Agreement until the Effective Time, and subject to any
         access, disclosure, copying or other limitations imposed by
         applicable law or the terms of any of the Company's or its
         subsidiaries' classified contracts (including any such con-
         tracts or arrangements with the U.S. or foreign governments),
         the Company will give Parent and its authorized representatives
         (including counsel, environmental and other consultants, ac-
         countants and auditors) access during normal business hours
         upon reasonable prior notice to all facilities, personnel and
         operations and to all books and records of the Company and its

                                     -24-

         subsidiaries, will permit Parent to make such inspections as it
         may reasonably require and will cause its officers and those of
         its subsidiaries to furnish Parent with such financial and op-
         erating data and other information with respect to its business
         and properties as Parent may from time to time reasonably re-
         quest.  Parent agrees that any information furnished to it, its
         subsidiaries or its authorized representatives pursuant to this
         Section 7.04 will be subject to the provisions of the letter
         agreement dated January 23, 1995 between Parent and the Company
         (the "Confidentiality Agreement").

                   Section 7.05.  Reasonable Best Efforts; Other Ac-
                                  ----------------------------------
         tions.  Subject to the terms and conditions herein provided and
         -----
         applicable law, each of the Company, Parent and the Purchaser
         shall use its reasonable best efforts promptly to take, or
         cause to be taken, all other actions and do, or cause to be
         done, all other things necessary, proper or appropriate under
         applicable laws and regulations to consummate and make effec-
         tive the transactions contemplated by this Agreement, includ-
         ing, without limitation, using such reasonable best efforts to
         (i) obtain all necessary consents, approvals or waivers under
         its material contracts and (ii) lift any legal bar to the
         Merger; provided, however, that the foregoing shall not require
         Parent, the Purchaser or any other affiliate of Parent to agree
         to any action or restriction which, if imposed by a governmen-
         tal entity, would constitute a condition described in paragraph
         (a) of Annex I to this Agreement.

                   Section 7.06.  Public Announcements.  Before issuing
                                  --------------------
         any press release or otherwise making any public statements
         with respect to this Agreement, the Offer or the Merger, Par-
         ent, the Purchaser and the Company will consult with each other
         as to its form and substance and shall not issue any such press
         release or make any such public statement prior to such con-
         sultation, except in either case as may be required by law or
         any obligations pursuant to any listing agreement with any na-
         tional securities exchange.

                   Section 7.07.  Notification of Certain Matters.  Each
                                  -------------------------------
         of the Company and Parent shall give prompt notice to the other
         party of (i) the occurrence, or non-occurrence, of any event
         the occurrence, or non-occurrence, of which would be likely to
         cause either (A) any representation or warranty of any party
         contained in this Agreement to be untrue or inaccurate in any
         material respect at any time from the date hereof to the
         acceptance for payment of Shares pursuant to the Offer, (B) any
         condition set forth in Annex I to be unsatisfied in any mate-
         rial respect at any time from the date hereof to the date the
         Purchaser purchases Shares pursuant to the Offer or (C) any
         condition set forth in Article VIII hereof to be unsatisfied in

                                     -25-
<PAGE>
 
         any material respect at any time from the date hereof to the
         Effective Time, and (ii) any material failure of the Company or
         Parent, as the case may be, or any officer, director, employee
         or agent thereof, to comply with or satisfy any covenant, con-
         dition or agreement to be complied with or satisfied by it
         hereunder; provided, however, that the delivery of any notice
         pursuant to this Section 7.07 shall not limit or otherwise
         affect the remedies available hereunder to the party receiving
         such notice.

                   Section 7.08.  Indemnification.  (a)  From and after
                                  ---------------
         the Effective Time, Parent shall, and shall cause the Surviving
         Corporation to, indemnify, defend and hold harmless the present
         and former officers, directors, employees and agents of the
         Company and its subsidiaries (the "Indemnified Parties")
         against all losses, claims, damages, expenses or liabilities
         arising out of or related to actions or omissions or alleged
         actions or omissions occurring at or prior to the Effective
         Time (i) to the full extent permitted by Delaware law or, if
         the protections afforded thereby to an Indemnified Person are
         greater, (ii) to the same extent and on the same terms and
         conditions (including with respect to advancement of expenses)
         provided for in the Company's Certificate of Incorporation and
         By-Laws and agreements in effect at the date hereof (to the
         extent consistent with applicable law), which provisions will
         survive the Merger and continue in full force and effect after
         the Effective Time.  Without limiting the foregoing, (i) Parent
         shall, and shall cause the Surviving Corporation to, periodi-
         cally advance expenses (including attorney's fees) as incurred
         by an Indemnified Person with respect to the foregoing to the
         full extent permitted under applicable law, and (ii) any de-
         termination required to be made with respect to whether an In-
         demnified Party shall be entitled to indemnification shall, if
         requested by such Indemnified Party, be made by independent
         legal counsel selected by the Surviving Corporation and rea-
         sonably satisfactory to such Indemnified Party. 

                   (b)  For a period of six years after the Effective
         Time, Parent shall cause to be maintained in effect the current
         policies of directors' and officers' liability insurance main-
         tained by the Company (provided that Parent may substitute
         therefor policies with reputable and financially sound carriers
         of at least the same coverage and amounts containing terms and
         conditions which are no less advantageous) with respect to
         claims arising from or related to facts or events which oc-
         curred at or before the Effective Time; provided, however, that
         Parent shall not be obligated to make annual premium payments
         for such insurance to the extent such premiums exceed 250% of
         the annual premiums paid as of the date hereof by the Company
         for such insurance (the "Maximum Amount").  If the amount of

                                     -26-
<PAGE>
 
         the annual premiums necessary to maintain or procure such in-
         surance coverage exceeds the Maximum Amount, Parent and the
         Surviving Corporation shall maintain the most advantageous
         policies of directors' and officers' insurance obtainable for
         an annual premium equal to the Maximum Amount.

                   (c)  The provisions of this Section 7.08 are intended
         to be for the benefit of, and shall be enforceable by each In-
         demnified Party, his or her heirs and his or her representa-
         tives.

                   Section 7.09.  Expenses.  Except as set forth in
                                  --------
         Section 9.05(b) hereof, Parent and the Company shall bear their
         respective expenses incurred in connection with this Agreement,
         the Offer and the Merger, including, without limitation, the
         preparation, execution and performance of this Agreement and
         the transactions contemplated hereby, and all fees and expenses
         of investment bankers, finders, brokers, agents, representa-
         tives, counsel and accountants.

                   Section 7.10.  Rights Agreement.  Except as contem-
                                  ----------------
         plated by Section 5.11 hereof, the Company shall not redeem the
         Rights or amend or terminate the Rights Agreement prior to the
         consummation of the Offer unless (i) required to do so by order
         of a court of competent jurisdiction (ii) the Board determines
         in good faith by a majority vote that the failure to make such
         redemption, amendment or termination would create a reasonable
         possibility of a breach of the Board's fiduciary duties under
         applicable law or (iii) this Agreement has theretofore been
         terminated.  

                   Section 7.11.  Employee Benefits.  (a)  Following the
                                  -----------------
         consummation of the Offer, (i) Purchaser shall cause the Com-
         pany to honor in accordance with their terms the employment
         contracts and other arrangements set forth on Schedule 7.11,
         the Company's Executive Supplemental Retirement Plan ("SERP"),
         the Trust Agreement between the Company and Society National
         Bank dated as of May 19, 1994, and the Trust Agreement between
         the Company and AmeriTrust Company National Association dated
         as of June 23, 1987, as amended, in each case as in effect on
         the date hereof and as amended as contemplated by this Agree-
         ment, and (ii) Parent shall unconditionally guarantee the
         prompt payment when due of all amounts payable pursuant to the
         terms of the aforementioned employment contracts and the SERP,
         including any costs incurred by employees or former employees
         (or their respective beneficiaries) in enforcing their rights
         under such contracts or under the SERP.  The provisions of the
         preceding sentence are intended to be for the benefit of, and
         shall be enforceable by, each of the employees and former em-
         ployees (and their respective beneficiaries) who are parties to

                                     -27-
<PAGE>
 
         such employment contracts or such other arrangements, who are
         participants in the SERP or such other arrangements, or who are
         beneficiaries under either of such Trust Agreements.  

                   (b)  Until the third anniversary of the Effective
         Time, Purchaser shall provide or cause the Company to provide
         to individuals who are employed by the Company or any of its
         subsidiaries employee benefits that are in the aggregate no
         less favorable than those provided to them as of the date
         hereof.  Without limiting the generality of the foregoing,
         Parent agrees that, following the Effective Time, employees of
         the Surviving Corporation shall be eligible to participate in
         Parent's various compensation plans on a basis comparable to
         that of similarly situated employees of Parent and its
         subsidiaries.  

                   (c)  Before the consummation of the Offer, the Com-
         pany shall take all steps necessary to ensure that none of the
         transactions contemplated by this Agreement shall constitute or
         result in a "Change of Control" as defined in the Company's
         Salaried Employees Retirement Plan and HRB Systems, Inc. Sala-
         ried Employees Retirement Plan.

                   (d)  Parent and Purchaser agree that prior to the
         consummation of the Offer, the Board (and following consumma-
         tion of the Offer and prior to the Effective Time, a majority
         of the Continuing Directors) may (i) amend the ESOP to provide
         for full vesting of all account balances and allocations of all
         unallocated shares, or the proceeds thereof, as of the Effec-
         tive Time, and to make other technical or administrative
         amendments related thereto, (ii) terminate the ESOP as of the
         Effective Time and provide for the orderly liquidation of the
         assets thereof or, with the consent of Purchaser (which consent
         shall not be unreasonably withheld), merge the ESOP with and
         into another tax-qualified plan, (iii) amend the Company's
         Employee Savings Plan to increase, as of the Effective Time,
         the Company's contributions thereunder to reflect any cessation
         of ESOP contributions (net of contributions for the benefit of
         employees of the Surviving Corporation under Parent's employee
         stock ownership plan ("Parent's ESOP"), as described in the
         succeeding sentence), (iv) authorize amendments to the employ-
         ment contract with the Company's Chairman and Chief Executive
         Officer to provide that such individual shall serve as Chief
         Executive Officer of the Surviving Corporation following the
         Effective Time and (unless he earlier resigns) for a period of
         3 years thereafter.  Parent and the Purchaser agree that if
         contributions to the ESOP cease on or after the Effective Time,
         then as of the date of such cessation, the employees of the
         Surviving Corporation and its subsidiaries who would otherwise
         have been eligible to receive allocations under the ESOP shall

                                     -28-
<PAGE>
 
         be eligible to participate in Parent's ESOP as of the date of
         such cessation.  For purposes of the preceding sentence, all
         service with the Company and its subsidiaries shall be recog-
         nized for eligibility and vesting purposes.  

                   (e)  Parent recognizes that the Company's business
         presents special situations with respect to the retention and
         recruitment of employees and executives and Parent agrees that
         the Chief Executive Officer of the Company may from time to
         time propose special arrangements for such employees and execu-
         tives for consideration by Parent.  Parent also recognizes that
         there are approximately 20 key executives of the Company who,
         in accordance with the usual procedures of the Compensation
         Committee of Parent, will receive appropriate consideration in
         connection with the grant of stock options by Parent at the
         customary time in July 1995.

         tive Time or as soon as practicable thereafter, Parent shall

         term ending at the 1998 annual meeting of stockholders of
         Parent.

         ------------------------------
         chaser's present intent to operate the Company as a subsidiary
         of Parent under the Company's current name, with the same man-
         agement and organizational structure and in its current head-
         quarters in Dallas, Texas.

                   Section 7.14.  EMASS.  Parent and the Purchaser
                                  -----
         acknowledge that they have been informed of the Company's
         business plan for EMASS and that they are aware of the Com-
         pany's commitment to implement that plan so long as it rep-
         resents sound business judgment.  Although Parent does not
         currently have sufficient information to commit to a specific
         course of action, Parent and the Purchaser currently plan to
         pursue and implement, within the same time frames and upon the
         same terms and conditions, that portion of such business plan
         that contemplates a public offering, spin-off or similar
         transaction with respect to the capital stock of EMASS so long
         as the management of the Purchaser and Parent concur with the
         management of the Company that plan implementation represents
         the exercise of sound business judgment.

         terminated (and the Merger contemplated hereby may be abandoned
         notwithstanding approval thereof by the stockholders of the
         Company) at any time prior to the Effective Time:

                   (a)  by mutual written consent of the Boards of Di-

                   (b)  by either Parent or the Company if, without any
              material breach of such terminating party of its obliga-
              tions under this Agreement, the purchase of Shares pursu-
              ant to the Offer shall not have occurred on or before
              September 30, 1995, which date may be extended by mutual
              written consent of the parties hereto;

                   (c)  by Parent or the Company if the Offer expires or
              is terminated or withdrawn pursuant to its terms without
              any Shares being purchased thereunder; provided, however,
              that Parent may not terminate this Agreement pursuant to
              this Section 9.01(c) if Parent's or the Purchaser's ter-
              mination of, or failure to accept for payment or pay for
              any Shares tendered pursuant to, the Offer does not follow

              of any condition set forth in Annex I hereto or is other-
              wise in violation of the terms of the Offer or this

              ernmental body in the United States shall have issued an
              order (other than a temporary restraining order), decree
              or ruling or taken any other action restraining, enjoining
              or otherwise prohibiting the purchase of Shares pursuant
              to the Offer or the Merger, and such order, decree, ruling
              or other action shall have become final and nonappealable;
              provided that the party seeking to terminate this Agree-
              ment shall have used its reasonable best efforts, subject
              to Section 7.05, to remove or lift such order, decree or
              ruling; or

                   (e)  by the Company if the Offer has not been timely
              commenced in accordance with Section 1.01(a) hereof.

                   Section 9.02.  Termination by Parent.  This Agreement
                                  ---------------------
         may be terminated and the Offer and the Merger may be abandoned
         by action of the Board of Directors of Parent, at any time
         prior to the purchase of Shares pursuant to the Offer, if (a)
         the Board shall withdraw, modify or change its recommendation
         or approval in respect of this Agreement or the Offer in a
         manner adverse to Parent, (b) the Board shall have recommended
         any proposal other than by Parent or the Purchaser in respect
         of an Acquisition Transaction or (c) any corporation, partner-
         ship, person, other entity or group (as defined in Section
         13(d)(3) of the Exchange Act) other than Parent or the Pur-
         chaser or any of their respective subsidiaries or affiliates

         outstanding Shares (either on a primary or a fully diluted
         basis).

                                  --------------------------
         Agreement may be terminated and the Merger may be abandoned by
         action of the Board, at any time prior to the Effective Time,
         (a) if there shall be a material breach of any of Parent's or
         the Purchaser's representations, warranties or covenants here-
         under, which breach shall not be cured within ten days of no-
         tice thereof, or (b) to allow the Company to enter into an
         agreement in respect of an Acquisition Transaction which the
         Board has determined is more favorable to the Company and its
         stockholders than the transactions contemplated hereby (pro-
         vided that the termination described in this clause (b) shall
         not be effective unless and until the Company shall have paid
         to Parent the fee described in Section 9.05(b) hereof).

         event of termination and abandonment of the Merger and the Of-
         fer by Parent or the Merger by the Company pursuant to this
         Article IX, written notice thereof shall forthwith be given to
         the other.

                                  ---------------------
         event of termination of this Agreement pursuant to this Article
         IX, the Merger shall be deemed abandoned and this Agreement
         shall forthwith become void, without liability on the part of
         any party hereto except as provided in this Section 9.05 and
         Sections 1.02(c) and 7.09 and the last sentence of Section
         7.04, except that nothing herein shall relieve any party from
         liability for any breach of this Agreement.

                   (b)  If (i) Parent shall have terminated this Agree-
         ment pursuant to Section 9.02 hereof or (ii) the Company shall
         have terminated this Agreement pursuant to Section 9.03(b)
         hereof, then in either such case the Company shall promptly,
         but in no event later than two business days after the date of
         such termination or event, pay Parent a termination fee of
         $75,000,000 plus an amount, not in excess of $20,000,000, equal
         to Parent's actual and reasonably documented out-of-pocket
         expenses directly attributable to the negotiation and execution
         of this Agreement and the attempted financing and completion of
         the Offer and the Merger, which amount shall be payable in same
         day funds, provided, that no fee or expense reimbursement shall
         be paid pursuant to this Section 9.05(b) if Parent shall be in
         material breach of its obligations hereunder.  In no event
         shall the Company be required to pay more than one termination
         fee and reimbursement of expenses pursuant to this Section
         9.05(b).

         adoption of this Agreement by the stockholders of the Company,
         no such amendment, modification or supplementation shall be

         subsidiaries, or (v) which otherwise would materially adversely
         affect the Company and its subsidiaries taken as a whole; or

                   (b)  this Agreement shall have been terminated by the
         Company, Parent or the Purchaser in accordance with its terms; or

                   (c)  (i)  the representations and warranties made by

         terial covenants to be performed and complied with by it under
         this Agreement; or

         Parent and the Purchaser and may be asserted by Parent or the
         Purchaser regardless of the circumstances (including any action
         or inaction by Parent or the Purchaser) giving rise to any such
         conditions and may be waived by Parent or the Purchaser in
         whole or in part at any time and from time to time, in each
         case, in the exercise of the good faith judgment of Parent and
         the Purchaser and subject to the terms of this Agreement.  The
         failure by Parent or the Purchaser at any time to exercise any
         of the foregoing rights shall not be deemed a waiver of any
         such right and each such right shall be deemed an ongoing right
         which may be asserted at any time and from time to time.
