To the Holders of Common Stock of
       LUMEN TECHNOLOGIES, INC.:
 
                                  INTRODUCTION
 
     Lighthouse Weston Corp., a Delaware corporation (the "Purchaser") and a
wholly owned subsidiary of EG&G, Inc., a Massachusetts corporation (the
"Parent"), hereby offers to purchase all outstanding shares of common stock, par
value $0.01 per share (the "Shares"), of Lumen Technologies, Inc., a Delaware
corporation (the "Company"), at a purchase price of $7.75 per Share, 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 with any amendments or supplements hereto or
thereto, collectively constitute the "Offer").
 
     The Offer is being made pursuant to an Agreement and Plan of Merger, dated
as of October 21, 1998 (the "Merger Agreement"), by and among the Parent, the
Purchaser and the Company. The Merger Agreement provides, among other things,
for the making of the Offer, and further provides that, following the
consummation of the Offer and the satisfaction of the other conditions set forth
in the Merger Agreement (but in no event prior to January 11, 1999, unless so
requested by the Parent) and in accordance with the relevant provisions of the
Delaware General Corporation Law (the "Delaware Law"), the Purchaser will be
merged with and into the Company (the "Merger"), the Company will be the
surviving corporation (the "Surviving Corporation") and the Surviving
Corporation will be a wholly owned subsidiary of the Parent. Upon the effective
time of the Merger (the "Effective Time"), each outstanding Share (other than
Shares held by the Parent, the Purchaser or the Company or any direct or
indirect subsidiary of the Parent, the Purchaser or the Company, and Shares held
by stockholders, if any, who are entitled to and perfect their appraisal rights
under Section 262 of the Delaware Law) will be cancelled and converted into the
right to receive $7.75 per Share in cash, or any higher price that may be paid
per Share in the Offer, without interest thereon (the "Merger Consideration").
 
     THE BOARD OF DIRECTORS OF THE COMPANY HAS UNANIMOUSLY DETERMINED THAT THE
OFFER AND THE MERGER ARE FAIR TO, AND IN THE BEST INTERESTS OF, THE STOCKHOLDERS
OF THE COMPANY, HAS APPROVED AND FOUND ADVISABLE THE MERGER AGREEMENT, THE OFFER
AND THE MERGER AND RECOMMENDS THAT THE STOCKHOLDERS OF THE COMPANY ACCEPT THE
OFFER AND TENDER THEIR SHARES PURSUANT TO THE OFFER.
 
     THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS, (1) THERE BEING VALIDLY
TENDERED AND NOT WITHDRAWN PRIOR TO THE EXPIRATION OF THE OFFER THAT NUMBER OF
SHARES WHICH CONSTITUTES AT LEAST A MAJORITY OF THE OUTSTANDING SHARES ON A
FULLY-DILUTED BASIS, AS DEFINED HEREIN (THE "MINIMUM CONDITION") AND (2) ANY
APPLICABLE WAITING PERIOD UNDER THE HART-SCOTT-RODINO ANTITRUST IMPROVEMENTS ACT
OF 1976, AS AMENDED, AND THE REGULATIONS THEREUNDER HAVING EXPIRED OR BEEN
TERMINATED. THE OFFER IS ALSO SUBJECT TO CERTAIN OTHER TERMS AND CONDITIONS
CONTAINED IN THIS OFFER TO PURCHASE. SEE SECTION 13.
 
     The Company has advised the Purchaser that Raymond James & Associates,
Inc., external investment banker to the Company (the "Company Investment
Banker"), has delivered to the Company's Board of Directors its written opinion
dated October 21, 1998, that on the basis of and subject to the matters set
forth therein, the cash consideration per Share to be received by the holders of
Shares (other than the Parent and its affiliates) in exchange for Shares
pursuant to the Offer and the Merger is fair, from a financial point of view, to
the Company and its stockholders (the "Fairness Opinion"). The Company has
delivered to the Purchaser a copy of the Fairness Opinion, together with the
Company Investment Banker's written consent to the inclusion of or reference to
the Fairness Opinion in the Tender Offer Statement on Schedule 14D-1 ("Schedule
14D-1") filed by the Purchaser and the Parent with the Securities and Exchange
Commission (the "Commission" or the "SEC") in connection with the Offer
(including this Offer to Purchase, the Letter of Transmittal and the other
exhibits to the Schedule 14D-1), the Schedule 14D-9 filed by the Company with
the Commission in connection with the Offer and any proxy or information
statement (the "Proxy Statement") that may be delivered to the stockholders of
the Company in connection with any vote of stockholders required with respect to
the Merger.
 
                                        1
<PAGE>   4
 
     The Company has filed with the Commission the Schedule 14D-9, which is
being mailed to stockholders of the Company concurrently herewith.
 
     The Company has advised the Purchaser that, as of October 21, 1998, there
were (i) 20,209,606 Shares issued and outstanding (net of 501,000 treasury
Shares), (ii) 3,613,325 Shares reserved for issuance pursuant to options
outstanding under the Company's option plans, (iii) 1,252,835 Shares reserved
for issuance upon conversion, at the conversion price of $9.89 per share, of the
outstanding principal under the Company's 8% Convertible Notes due 2002 (the
"Convertible Notes") and (iv) no other Shares reserved for issuance for any
purpose. For purposes of calculating the Minimum Condition, the term "fully
diluted basis" includes Shares reserved for issuance pursuant to options
outstanding under the Company's option plans (except to the extent such Shares
would, following exercise, be subject to the Stockholders' Agreement (described
below)), but excludes Shares reserved for issuance with respect to the
Convertible Notes. See Section 13. Based upon 22,070,593 Shares outstanding on a
fully-diluted basis as of October 21, 1998, 11,035,297 Shares must be tendered
in order to satisfy the Minimum Condition.
 
     The Parent and the Purchaser have entered into a Stockholders' Agreement
with certain officers and directors of the Company (the "Management
Stockholders"), with respect to 993,684 Shares outstanding as of the date of the
Merger Agreement and beneficially owned by the Management Stockholders and an
additional 1,752,338 Shares subject to options held by the Management
Stockholders. The Shares subject to the Stockholders' Agreement represent
between 4.5% (assuming the Management Stockholders do not exercise any of their
options) and 11.5% (assuming the Management Stockholders exercise all of their
options) of the Fully Diluted Shares (as defined herein). Pursuant to the
Stockholders' Agreement, the Management Stockholders have agreed to tender all
their outstanding Shares pursuant to the Offer, to vote all their outstanding
Shares in favor of the Merger and not to transfer such Shares without the
Parent's consent and have granted the Purchaser a proxy to vote such Shares in
favor of the Merger.
 
     The Company has represented to the Parent and the Purchaser that, in
addition to the obligations of the Management Stockholders pursuant to the
Stockholders' Agreement, each member of the Company's Board of Directors and
each executive officer of the Company has advised the Company that his current
intention is to tender all Shares, if any, beneficially owned by him pursuant to
the Offer, other than those individuals, if any, for whom the tender of such
Shares (the "Section 16 Shares") would cause them to incur liability under the
provisions of Section 16(b) of the Securities Exchange Act of 1934, as amended
(the "Exchange Act"). As to the Section 16 Shares, if any, the Company has
represented to the Parent and the Purchaser that each such director and
executive officer has advised the Company that it is his current intention to
vote such Shares in favor of the Merger.
 
     The consummation of the Merger is subject to the satisfaction or waiver of
certain conditions, including the approval and adoption of the Merger Agreement
by the requisite vote or consent of the stockholders of the Company, if required
by the Delaware Law. Under the Delaware Law, if the Purchaser acquires at least
a majority of the outstanding Shares, the Purchaser would have sufficient voting
power to approve and adopt the Merger Agreement, and consummate the Merger
without the vote or consent of any other stockholder. In addition, under the
Delaware Law, if the Purchaser acquires at least 90% of the outstanding Shares,
the Purchaser would have the power to approve and adopt the Merger Agreement,
and consummate the Merger, without a vote of the Company's stockholders. In
either event, the Purchaser intends to take all necessary and appropriate action
to cause the Merger to become effective as soon as reasonably practicable after
the consummation of the Offer (but in no event prior to January 11, 1999, unless
so requested by the Parent). THE PURCHASER IS NOT SOLICITING STOCKHOLDER
PROXIES, AND THIS OFFER DOES NOT CONSTITUTE SUCH A SOLICITATION. ANY
SOLICITATION BY THE PURCHASER OR THE COMPANY OF PROXIES OR CONSENTS FROM THE
COMPANY'S STOCKHOLDERS WILL NOT COMMENCE UNTIL, IF REQUIRED UNDER THE
COMMISSION'S PROXY RULES, PROXY MATERIALS ARE FILED WITH THE COMMISSION AND
FURNISHED TO STOCKHOLDERS.
 
     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 with respect to the purchase by the Purchaser
of Shares pursuant to the Offer. The Purchaser will pay all fees and expenses of
BankBoston, N.A., which is acting as the Depository (the "Depositary"), and
Kissel-Blake, which is acting as the Information Agent (the "Information
Agent"), incurred in connection with the Offer. See Section 16.
 
     THIS OFFER TO PURCHASE AND THE RELATED LETTER OF TRANSMITTAL CONTAIN
IMPORTANT INFORMATION THAT SHOULD BE READ CAREFULLY BEFORE ANY DECISION IS MADE
WITH RESPECT TO THE OFFER.

                                THE TENDER OFFER
 
1.  TERMS OF THE OFFER; EXPIRATION DATE
 
     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 pay for all Shares
validly tendered prior to the Expiration Date (as defined below) and not
properly withdrawn as provided in Section 4. The term "Expiration Date" means
12:00 midnight, New York City time, on Tuesday, November 24, 1998, unless and
until the Purchaser, in its sole discretion (but subject to the terms and
conditions of the Merger Agreement), shall have extended the period during which
the Offer is open, in which event the term "Expiration Date" shall mean the
latest time and date at which the Offer, as so extended by the Purchaser, shall
expire.
 
     Subject to the applicable rules and regulations of the Commission, the
Purchaser expressly reserves the right, in its sole discretion (but subject to
the terms and conditions of the Merger Agreement), at any time and from time to
time, and regardless of whether or not any of the events set forth in Section 13
of this Offer to Purchase shall have occurred, to extend the period during which
the Offer is open and thereby delay acceptance for payment of, and payment for,
any Shares, by giving oral or written notice of such extension to the
Depositary. There can be no assurance that the Purchaser will exercise its right
to extend the Offer (other than as may be required by law). During any such
extension, all Shares previously tendered and not properly withdrawn will remain
subject to the Offer, subject to the rights of a tendering stockholder to
withdraw such stockholder's Shares. See Section 4.
 
     Subject to the applicable rules and regulations of the Commission, the
Purchaser also expressly reserves the right, in its sole discretion (but subject
to the terms and conditions of the Merger Agreement), at any time and from time
to time, to (i) delay acceptance for payment of or, regardless of whether the
Shares were theretofore accepted for payment, payment for, any Shares pending
receipt of any regulatory approvals specified in Section 14, (ii) terminate the
Offer and not accept for payment (or pay for) any Shares if any of the
conditions referred to in Section 13 has not been satisfied or upon the
occurrence and during the continuance of any of the events specified in Section
13, and (iii) waive any condition or 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 by making a public announcement thereof. The
Merger Agreement provides that, without the consent of the Company, the
Purchaser shall not amend or waive the Minimum Condition, reduce the maximum
number of Shares to be purchased, reduce the price to be paid per Share pursuant
to the Offer, change the form of consideration to be paid in the Offer, impose
conditions to the Offer in addition to those set forth in Section 13, or amend
any other material term of the Offer in a manner adverse to the holders of the
Shares. The Merger Agreement further provides that, notwithstanding the
foregoing, the Purchaser may, in its sole discretion, (A) extend the Offer if at
the scheduled or any extended expiration date of the Offer any of the conditions
set forth in Section 13 (including the Minimum Condition) shall not be satisfied
or waived, until such time as such conditions are satisfied or waived, and (B)
extend the Offer for any period required by any rule, regulation, interpretation
or position of the Commission or the staff thereof applicable to the Offer;
provided, however, that, without the Company's written consent, the Purchaser
may not extend the expiration date of the Offer to a date later than 11:59 p.m.
on December 31, 1998. The Purchaser acknowledges (x) that Rule 14e-1(c) under
the Exchange Act requires the Purchaser to pay the consideration offered or
return the Shares tendered promptly after the termination or withdrawal of the
Offer and (y) that the Purchaser may not delay acceptance for payment of, or
payment for (except as provided in clause (i) of the first sentence of this
paragraph), any Shares upon the occurrence of any of the conditions specified in
Section 13 without extending the period during which the Offer is open.
 
     If the Minimum Condition or any other condition specified in Section 13 is
not fulfilled by the Expiration Date, the Purchaser reserves the right (but
shall not be obligated) to (i) decline to purchase any of the Shares tendered,
return all tendered Shares to tendering stockholders and terminate the Offer,
(ii) subject to the terms and conditions of the Merger Agreement, extend the
Offer and retain all tendered Shares until the expiration of the Offer, as
extended, subject to the terms and conditions of the Offer (including any rights
of stockholders to withdraw their Shares), or (iii) subject to the terms and
conditions of the Merger Agreement,
                                        3
<PAGE>   6
 
waive or reduce the condition and, subject to complying with applicable rules
and regulations of the Commission, accept for payment and purchase all Shares
validly tendered.
 
     Any extension, termination, or amendment of the Offer will be followed by a
public announcement thereof, such announcement, in the case of an extension, to
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, except as
provided by applicable law (including Rules 14d-4(c), 14d-6(d) and 14e-1 under
the Exchange Act, which require that material changes be promptly disseminated
to holders of Shares), the Purchaser will 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.
 
     If, in accordance with the terms and conditions of the Merger Agreement,
the Purchaser makes a material change in the terms of the Offer or the
information concerning the Offer, or waives a material condition of the Offer,
the Purchaser will disseminate additional tender offer materials (including by
public announcement as set forth above) and extend the Offer 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 or information concerning the offer, other than a
change in price, a change in percentage of securities sought or a change in any
dealer's soliciting fee, will depend upon the facts and circumstances, including
the relative materiality of the changes. With respect to a change in price or,
subject to certain limitations, a change in the percentage of securities sought
or a change in any dealer's soliciting fee, a minimum ten business day period
from the day 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, increases the
consideration offered pursuant to the Offer or adds a dealer's soliciting fee,
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,
decrease or addition is first published, sent or given to stockholders, the
Offer will be extended at least until the expiration of such ten business day
period. For purposes of the Offer, a "business day" means any day other than a
Saturday, Sunday or a federal holiday and consists of the time period from 12:01
a.m. through 12:00 midnight, New York City time.
 
     The Company has provided the Purchaser with the Company's stockholder list
and security position listings for the purpose of disseminating the Offer to
holders of Shares. This Offer to Purchase and the related Letter of Transmittal
and, if required, other relevant material 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 Company's stockholder list 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 FOR SHARES
 
     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 purchase by accepting for payment, and will
pay for, all Shares validly tendered prior to the Expiration Date and not
properly withdrawn (including Shares validly tendered and not withdrawn during
any extension of the Offer, if the Offer is extended, subject to the terms and
conditions of such extension), promptly after the later of (i) the Expiration
Date and (ii) the expiration or termination of the waiting period under the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR
Act"), applicable to the Purchaser's purchase of Shares pursuant to the Offer.
In addition, subject to complying with Rule 14e-1 under the Exchange Act, the
Purchaser expressly reserves the right, in its sole discretion (but subject to
the terms and conditions of the Merger Agreement), to delay the acceptance for
payment of, or payment for, Shares in order to comply, in whole or in part, with
any other applicable law.
 
     On October 22, 1998, the Parent filed with the Federal Trade Commission
(the "FTC") and the Antitrust Division of the Department of Justice (the
"Antitrust Division") a Premerger Notification and Report Form under the HSR Act
with respect to the Offer. Accordingly, it is anticipated that the waiting
 
                                        4
<PAGE>   7
 
period under the HSR Act applicable to the Offer will expire at 11:59 p.m., New
York City time, on November 6, 1998. However, prior to the expiration or
termination of the waiting period, the FTC or the Antitrust Division may extend
the waiting period applicable to the Offer by requesting additional information
from the Parent. If such a request is made, the waiting period applicable to the
Offer will expire on the tenth calendar day after the date of substantial
compliance by the Parent with such request. Thereafter, the waiting period may
only be extended by court order or with the agreement of the Parent. The waiting
period under the HSR Act may be terminated by the FTC and the Antitrust Division
prior to its expiration. The Parent has requested early termination of the
waiting period applicable to the Offer, although there can be no assurance that
this request will be granted. See Section 14 for additional information
regarding the HSR Act.
 
     In all cases, payment for Shares tendered and accepted for payment pursuant
to the Offer will be made only after timely receipt by the Depositary of (i)
certificates evidencing Shares ("Share Certificates") or timely confirmation of
a book-entry transfer of such Shares ("Book-Entry Confirmation") into the
Depositary's account at The Depository Trust Company (the "Book-Entry Transfer
Facility") pursuant to the procedures set forth in Section 3, (ii) 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 below) in
connection with a book-entry transfer and (iii) any other documents required by
the Letter of Transmittal. Accordingly, payment may be made to tendering
stockholders at different times if delivery of the Shares and other required
documents occurs at different times.
 
     The term "Agent's Message" means a message transmitted by the Book-Entry
Transfer Facility to, and received by, the Depositary and forming a part of a
Book-Entry Confirmation, which states that the Book-Entry Transfer Facility has
received an express acknowledgment from the participant in the 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 properly
withdrawn if, as and when the Purchaser gives oral or written notice to the
Depositary of the Purchaser's acceptance for payment of such Shares pursuant to
the Offer. Upon the terms and subject to the conditions of the Offer, payment
for Shares so accepted for payment pursuant to the Offer will be made by deposit
of the aggregate 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 such payment to stockholders whose Shares have been
accepted for payment. UNDER NO CIRCUMSTANCES WILL INTEREST ON THE PURCHASE PRICE
FOR SHARES BE PAID, REGARDLESS OF ANY EXTENSION OF THE OFFER OR DELAY IN MAKING
SUCH PAYMENT. Upon the deposit of funds with the Depositary for the purpose of
making payment to validly tendering stockholders, the Purchaser's obligation to
make such payment shall be satisfied and such tendering stockholders must
thereafter look solely to the Depositary for payment of the amounts owed to them
by reason of the acceptance for payment of Shares pursuant to the Offer.
 
     If any tendered Shares are not accepted for payment pursuant to the terms
and conditions of the Offer for any reason, or if Share Certificates are
submitted for more Shares than are tendered, Share Certificates evidencing
Shares not purchased or not tendered will be returned, without expense to the
tendering stockholder (or, in the case of Shares tendered by book-entry transfer
of such Shares into the Depositary's account at the Book-Entry Transfer Facility
pursuant to the procedures for book-entry transfer set forth in Section 3, such
Shares will be credited to an account maintained at the Book-Entry Transfer
Facility), as soon as practicable following expiration or termination of the
Offer.
 
     If, prior to the Expiration Date, the Purchaser increases the consideration
to be paid per Share, the Purchaser will pay such increased consideration for
all Shares purchased pursuant to the Offer, whether or not such Shares have been
tendered or purchased prior to such increase in consideration.
 
     Subject to the terms and conditions of the Merger Agreement, the Parent and
the Purchaser reserve the right to transfer or assign, in whole or in part from
time to time, to one or more of their affiliates, the right to purchase the
Shares tendered pursuant to the Offer, but any such transfer or assignment will
not relieve the Parent or the Purchaser of their respective obligations under
the Offer, nor will any such transfer or
                                        5
<PAGE>   8
 
assignment in any way 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
 
     General.  Except as set forth below, in order for Shares to be validly
tendered pursuant to the Offer, the Letter of Transmittal (or facsimile
thereof), properly completed and duly executed, together 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 prior to the Expiration Date,
and either (i) Share Certificates evidencing tendered Shares must be received by
the Depositary at such address or such Shares must be tendered pursuant to the
procedures for book-entry transfer set forth below (and a Book-Entry
Confirmation must be received by the Depositary), in each case prior to the
Expiration Date, or (ii) the guaranteed delivery procedures set forth below must
be complied with.
 
     No alternative, conditional or contingent tenders will be accepted and no
fractional Shares will be purchased. All tendering stockholders, by execution of
the Letter of Transmittal (or facsimile thereof) waive any right to receive any
notice of the acceptance of their Shares for payment.
 
     THE METHOD OF DELIVERY OF SHARE CERTIFICATES, THE LETTER OF TRANSMITTAL AND
ALL OTHER REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH THE BOOK-ENTRY TRANSFER
FACILITY, IS AT THE SOLE OPTION AND RISK OF EACH 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.
 
     Book-Entry Transfer.  The Depositary will make a request to establish an
account with respect to the Shares at the Book-Entry Transfer Facility 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 the
Book-Entry Transfer Facility may make book-entry delivery of Shares by causing
the Book-Entry Transfer Facility to transfer such Shares into the Depositary's
account at the Book-Entry Transfer Facility in accordance with the 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 the Book-Entry Transfer Facility, the Letter of Transmittal (or facsimile
thereof), properly completed and duly executed, together with any required
signature guarantees, or an Agent's Message, and any other documents required by
the Letter of Transmittal, must, in any case, be received by the Depositary at
one of its addresses set forth on the back cover of this Offer to Purchase prior
to the Expiration Date in order for such Shares to be validly tendered pursuant
to the Offer, or the tendering stockholder must comply with the guaranteed
delivery procedures described below.
 
     DELIVERY OF DOCUMENTS TO THE BOOK-ENTRY TRANSFER FACILITY IN ACCORDANCE
WITH THE 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 commercial bank, broker, dealer, credit union,
savings association or other entity which is a member in good standing of the
Securities Transfer Agents Medallion Program, the Stock Exchanges' Medallion
Program or the New York Stock Exchange, Inc. ("NYSE") Medallion Signature
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 entitled "Special Delivery Instructions" or the box entitled "Special
Payment 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, or Share
Certificates for unpurchased Shares are to be returned, to a person other than
the registered holder(s), then the tendered Share Certificates must be endorsed
or accompanied by appropriate stock powers signed exactly as the name(s) of the
registered holder(s) appear on the Share Certificates with the signature(s) on
such Share Certificates or stock powers guaranteed by an
 
                                        6
<PAGE>   9
 
Eligible Institution as provided above and in the Letter of Transmittal. See
Instructions 1 and 5 of the Letter of Transmittal.
 
     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 of the required documents to reach the
Depositary prior to the Expiration Date, or the procedure for book-entry
transfer cannot be completed on a timely basis, such Shares may nevertheless be
tendered, provided that all of the following conditions are satisfied:
 
          (a) such tender is made by or through an Eligible Institution;
 
          (b) a properly completed and duly executed Notice of Guaranteed
     Delivery, substantially in the form provided by the Purchaser herewith, is
     received by the Depositary, as provided below, prior to the Expiration
     Date; and
 
          (c) the Share Certificates (or a Book-Entry Confirmation) for all
     tendered Shares, in proper form for transfer, in each case together with
     the Letter of Transmittal (or a facsimile thereof), properly completed and
     duly executed, 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 three 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 transmitted
by telegram, facsimile transmission or mail to the Depositary and must include a
guarantee by an Eligible Institution in the form set forth in the Notice of
Guaranteed Delivery.
 
     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 therefor (or Book-Entry
Confirmation of the transfer of such Shares into the Depositary's account at the
Book-Entry Transfer Facility), 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 Letter of Transmittal. Accordingly, payment
might not be made to all tendering stockholders at the same time, and will
depend upon when Share Certificates or Book-Entry Confirmations of such Shares
are received by the Depositary.
 
     Backup Federal Income Tax Withholding.  Under the U.S. federal income tax
laws, the Depositary may, under certain circumstances, be required to withhold
31% of the amount of any payments made to certain stockholders pursuant to the
Offer. To prevent such backup federal income tax withholding with respect to
payments made to certain stockholders of the purchase price of Shares purchased
pursuant to the Offer, 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 constitutes and appoints designees of the Purchaser as
the stockholder's attorneys-in-fact and proxies in the manner set forth in the
Letter of Transmittal, each with full power of substitution with respect to any
Shares tendered thereby (and with respect to any and all other Shares or other
securities issued or issuable in respect of such Shares on or after October 21,
1998). 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 when, and only to the extent that, the Purchaser accepts such Shares
for payment and deposits the purchase price therefor with the Depositary. Upon
such deposit, all prior powers of attorney and proxies given by such stockholder
at any time with respect to such Shares (and other Shares and securities issued
or issuable in respect of such Shares on or after October 21, 1998) will,
without further action, be revoked, and no subsequent powers of attorney or
proxies may be given nor any subsequent written consents executed by such
stockholder (and, if given or executed, will not be deemed effective). Upon such
deposit by the Purchaser, the designees of the Purchaser will, with respect to
such Shares and other securities, 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
                                        7
<PAGE>   10
 
special meeting of the Company's stockholders, or any adjournment or
postponement thereof, by written consent in lieu of any such meeting or
otherwise. The Purchaser reserves the right to require that, in order for Shares
to be deemed validly tendered, immediately upon the Purchaser's payment for such
Shares, the Purchaser must be able to exercise full voting and other rights of a
record and beneficial holder, including, without limitation, voting at any
meeting of stockholders or by written consent in lieu of any such meeting.
 
     Determination of Validity.  All questions as to the validity, form,
eligibility (including the time of receipt) and acceptance for payment of any
tendered Shares pursuant to any of the procedures described above will be
determined by the Purchaser, in its sole discretion, which determination will be
final and binding on all parties. The Purchaser reserves the absolute right to
reject any and all tenders of any particular Shares determined by it not to be
in appropriate form or the acceptance of or payment for which may, in the
opinion of its counsel, be unlawful. The Purchaser also reserves the absolute
right to waive any of the conditions of the Offer (subject to the terms and
conditions of the Merger Agreement) or any defect or irregularities in the
tender of any particular Shares, whether or not similar defects or
irregularities are waived in the case of any other Shares. The Purchaser's
interpretations of the terms and conditions of the Offer (including the Letter
of Transmittal and Instructions thereto) will be final and binding. No tender of
Shares will be deemed to have been validly made until all defects and
irregularities have been cured or waived. None of the Parent, the Purchaser, any
of their respective affiliates or assigns, the Information Agent, the Depositary
or any other person will be under any duty to give 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 THE
OFFER 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 prior to the Expiration Date and, unless theretofore
accepted for payment as provided herein, may also be withdrawn at any time after
December 25, 1998.
 
     If the Purchaser extends the Offer, is delayed in, or delays, its
acceptance for payment or payment for Shares or is unable to accept for payment
or pay for Shares for any reason, then, without prejudice to the Purchaser's
other rights under the Offer, tendered Shares may nevertheless be retained by
the Depositary, on behalf of the Purchaser, and may not be withdrawn except to
the extent tendering stockholders are entitled to and duly exercise withdrawal
rights as described in this Section 4. Any such delay will be accompanied 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 the name of the
registered holder of the Shares to be withdrawn, if different from that of the
person who tendered such Shares. If Share Certificates to be withdrawn have been
delivered or otherwise identified to the Depositary, then, prior to the physical
release of such Share Certificates, the tendering stockholder must also submit
the serial numbers shown on such Share Certificates to the Depositary and the
signatures on the notice of withdrawal must be guaranteed by an Eligible
Institution, unless such Shares have been tendered for the account of an
Eligible Institution. If Shares have been tendered pursuant to the procedures
for book-entry transfer, as set forth in Section 3, any notice of withdrawal
must specify the number of the account at the Book-Entry Transfer Facility to be
credited with the withdrawn Shares and must otherwise comply with the procedure
of the Book-Entry Transfer Facility.
 
     Withdrawals may not be revoked and any Shares properly withdrawn will
thereafter be deemed not to have been validly tendered for purposes of the
Offer. However, withdrawn Shares may be retendered at any time prior to the
Expiration Date by following one of the procedures described in Section 3.
 
                                        8
<PAGE>   11
 
     All questions as to the form and validity (including the time of receipt)
of any notice of withdrawal will be determined by the Purchaser, in its sole
discretion, whose determination will be final and binding on all parties. None
of the Parent, the Purchaser, any of their respective affiliates or assigns, the
Information Agent, the Depositary or any other person will be under any duty to
give notification of any defects or irregularities in any notice of withdrawal
or incur any liability for failure to give any such notification.
 
5.  CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
     The following is a summary of the material U.S. federal income tax
consequences of the Offer and the Merger to the holders of Shares. This summary
is based upon the provisions of the Internal Revenue Code of 1986, as amended
(the "Code"), applicable treasury regulations thereunder, judicial decisions and
current administrative rulings. The discussion does not address all aspects of
U.S. federal income taxation that may be relevant to particular taxpayers in
light of their personal investment circumstances or to taxpayers subject to
special treatment under the Code (for example, dealers in securities, financial
institutions, insurance companies, foreign corporations, individuals who are not
citizens or residents of the United States and holders whose Shares were
acquired pursuant to the exercise of employee stock options or in other
compensatory transactions) and does not address any aspect of state, local,
foreign or other taxation.
 
     For federal income tax purposes, a tendering stockholder will generally
recognize gain or loss equal to the difference between the amount of cash
received by the stockholder pursuant to the Offer (or pursuant to the Merger)
and the aggregate tax basis in the Shares tendered by the stockholder and
purchased pursuant to the Offer (or cancelled pursuant to the Merger). Gain or
loss will be calculated separately for each block of Shares tendered and
purchased pursuant to the Offer (or cancelled pursuant to the Merger).
 
     If Shares are held by a stockholder as capital assets, gain or loss
recognized by the stockholder will be capital gain or loss, which will be
long-term capital gain or loss if the stockholder's holding period for the
Shares exceeds one year. Long-term capital gains recognized by an individual
stockholder will generally be taxed at a maximum federal marginal tax rate of
20%, and long-term capital gains recognized by a corporate stockholder will be
taxed at a maximum federal marginal tax rate of 35%.
 
     A stockholder (other than corporations and certain foreign individuals)
that tenders Shares may be subject to 31% backup withholding unless the
stockholder provides the stockholder's social security or other taxpayer
identification number ("TIN") and certifies that such number is correct or
properly certifies that the stockholder is awaiting a TIN and certifies as to no
loss of exemption from backup withholding, and otherwise complies with the
applicable requirements of the backup withholding rules. A stockholder that does
not furnish the stockholder's correct TIN or that does not otherwise establish a
basis for an exemption from backup withholding may be subject to a penalty
imposed by the Internal Revenue Service. Each stockholder should complete and
sign the substitute Form W-9 included as part of the Letter of Transmittal so as
to provide the information and certification necessary to avoid backup
withholding.
 
     If backup withholding applies to a stockholder, the Depositary is required
to withhold 31% from payments to such stockholder. Backup withholding is not an
additional tax. Any amount withheld from a payment to a stockholder is allowable
as a credit against such stockholder's federal income tax liability, provided
that the required information is provided to the Internal Revenue Service.
 
     EACH HOLDER OF SHARES IS URGED TO CONSULT SUCH HOLDER'S TAX ADVISOR AS TO
THE SPECIFIC TAX CONSEQUENCES TO SUCH HOLDER OF THE OFFER AND THE MERGER,
INCLUDING THE APPLICATION OF STATE, LOCAL, FOREIGN AND OTHER TAX LAWS.

- ---------------
(1) Reflects the actual historical financial results of the Company for the
    indicated periods. These financial results should be read in conjunction
    with the Company's financial statements and related notes set forth in the
    Company Reports. The Company acquired ILC on March 12, 1998. The acquisition
    was accounted for as a purchase in accordance with APB No. 16 and
    accordingly, the results of operations of ILC are included in the Company's
    financial results from March 12, 1998. Additionally, as of January 1, 1998,
    the Company increased its effective common stock ownership of Voltarc
    Technologies Inc. ("Voltarc") to 50%. Accordingly, the Company has
    consolidated the results of operations and balance sheet of Voltarc from
    that date. The Voltarc investment was previously accounted for on the equity
    method.
 
(2) Discontinued operations reflect the results of (a) Bolle, which was spunoff
    to the Company's stockholders on March 11, 1998, (b) the subsidiaries of the
    Company comprising the Company's Foster Grant Group, which was sold by the
    Company on December 12, 1996, and (c) the Omega Group, the wholesale optical
    laboratory business of the Company's predecessor, and Orcolite, the lens
    manufacturing business of the Company's predecessor, which were sold by the
    Company on May 3, 1996.

     On October 26, 1998, the Company issued a press release summarizing the
Company's financial results for the third quarter and the nine months ended
September 30, 1998. In the press release, the Company reported:
 
          (i) for the third quarter ended September 30, 1998, net sales of $37.0
     million, compared to 1997 net sales of $12.1 million; operating profit of
     $3.5 million, compared to 1997 operating profit of $1.0 million; and net
     income from continuing operations of $2.3 million, or $0.11 per share,
     compared to $0.7 million, or $0.08 per share, in 1997; and
 
          (ii) for the nine months ended September 30, 1998, net sales of $105.9
     million, compared to 1997 net sales of $35.2 million; and net loss of $10.1
     million, or $(0.57) per share, compared to net income of $3.1 million, or
     $0.35 per share, in 1997.
 
     The Company also noted in the press release that period to period results
were not comparable due to transactions undertaken by Lumen during 1998 and that
the results for the nine months ended September 30, 1998 reflected nonrecurring,
non-cash charges of $16.7 million related to the merger and spin-off recorded in
the first quarter of 1998.
 
     During the course of discussions between the Parent and the Company that
led to the execution of the Merger Agreement (see Section 10), the Parent had
access to certain non-public business and financial information about the
Company. As part of this information, the Parent had access to a statement of
operations for 1998, 1999 and 2000, which, for periods after 1998, was based on
a numerical extrapolation of the Company's pro forma results for 1997. The
Company has advised the Parent that such extrapolated statement of operations,
which indicated net sales for 1998 and 1999 of $153.5 million and $175.4
million, respectively, net income for 1998 and 1999 of $7.7 million and $11.6
million, respectively, and further increases in net sales and net income for
2000, was based, for periods after 1998, on a numerical extrapolation of the
Company's pro forma results for 1997 and was not based on any detailed forecast
of the Company for such future periods, or on any consideration of trends,
changes in market conditions, or any other relevant factors.
 
     The Company has advised the Parent that the Company does not as a matter of
course make public any forecasts or projections as to future performance or
earnings, and the information set forth in the preceding paragraph is included
in the Offer to Purchase only because Parent had access to such information. The
financial information set forth in the preceding paragraph was 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 forecasts. None of the Purchaser,
the Parent or the Company assumes any responsibility for the validity,
reasonableness, accuracy or completeness of the financial information in the
preceding paragraph, and the Company has made no representation to the Parent or
the Purchaser regarding the financial information described in the preceding
paragraph. While presented with numerical specificity, this information is
subject to significant uncertainties and contingencies, all of which are
difficult to predict and many of which are beyond the control of the Company.
There can be no assurance that the results set forth in the preceding paragraph
will be realized, and actual results may vary materially and adversely from
those shown. The inclusion of this forward-looking information should not be
regarded as fact or an indication that the Parent, the Purchaser, the Company or
anyone who received this information considered it a reliable predictor of
future results, and this information should not be relied on as such.

(1) Included an asset impairment charge of $28.2 million, $23.5 million
    after-tax ($0.51 earnings per share).
 
(2) Included restructuring charges of $54.5 million, $39.5 million after-tax

    million after-tax ($0.10 earnings per share); and gains on dispositions of

     On October 21, 1998, the Parent issued a press release summarizing the
Parent's financial results for the third quarter and nine months ended September
27, 1998. For the third quarter, the Parent reported sales of $343.5 million and
net income of $14.6 million, or $0.32 per diluted share. For the first nine
months of 1998, the Parent reported sales of $1,055.7 million and net income of
$81.5 million, or $1.77 per diluted share.
 
9.  SOURCE AND AMOUNT OF FUNDS
 
     The total amount of funds required by the Purchaser to purchase 23,822,931
Shares pursuant to the Offer (which represents all issued and outstanding Shares
and all Shares issuable upon the exercise of outstanding
 
                                       15
<PAGE>   18
 
options, but excludes any Shares issuable upon conversion of the Convertible
Notes), and to pay related fees and expenses is estimated to be approximately
$185.5 million. The Purchaser will obtain such funds from the Parent. The Parent
intends to obtain such funds from its available corporate funds, from the
issuance of commercial paper and from borrowings under its existing bank
financing facilities. The Parent may also enter into one or more new bank
facilities and use proceeds from such facilities to obtain the funds required to
purchase Shares pursuant to the Offer. The obtaining of financing is not a
condition to the Offer or the Merger.
 
     The Parent has two existing revolving credit agreements. Under the
Company's 364-Day Competitive Advance and Revolving Credit Facility Agreement
dated as of March 6, 1998, among the Parent, the Borrowing Subsidiaries (as
defined therein), the Lenders listed therein and Chase Manhattan Bank, the
Company may borrow up to $100 million. This facility requires a commitment fee
of six basis points and provides that any indebtedness outstanding under the
facility bears interest at a rate equal to 25 basis points over LIBOR. Advances
under this facility mature in March 1999. Under the Company's Five-Year
Competitive Advance and Revolving Credit Facility Agreement dated as of March
21, 1994, as amended, among the Parent, Lenders listed therein and Chase
Manhattan Bank as Administrative Agent the Company may borrow up to $100
million. This facility requires a commitment fee of eight basis points and
provides that any indebtedness outstanding under the facility bears interest at
a rate equal to 25 basis points over LIBOR. This facility expires in March 2002.
Both facilities are unsecured and contain a number of non-financial and
financial covenants. As of October 26, 1998, the Parent had no indebtedness
outstanding under either facility.
 
     It is anticipated that the indebtedness incurred by the Parent in
connection with the Offer and the Merger will be repaid from funds generated
internally by the Parent and its subsidiaries (including, after the Merger, if
consummated, funds generated by the Surviving Corporation and its subsidiaries)
and through other sources which may include the proceeds of future bank
financings, the public or private sale of debt or equity securities or a
combination thereof. No decisions have been made, however, concerning the method
the Parent will employ to repay such indebtedness. Such decisions, when made,
will be based on the Parent's review from time to time of the advisability of
particular actions, as well as on prevailing interest rates and financial and
other economic conditions.
 
10.  BACKGROUND OF THE OFFER; CONTACTS WITH THE COMPANY
 
     Over the past few years, representatives of the Parent and the Company have
had informal contacts at trade shows and lighting industry events.
 
     At the beginning of May, 1998, Angelo D. Castellana, Senior Vice President
of the Parent, called Martin E. Franklin, Chairman of the Board of Directors of
the Company. During their conversation the parties acknowledged their mutual
interest to continue discussions regarding possible strategic opportunities
between the Parent and the Company.
 
     On May 5, 1998, Messrs. Castellana and Franklin had dinner, at which they
continued to discuss a variety of strategic opportunities, including
alternatives involving the Company and the Parent's Optoelectronics Business
Unit. They agreed to meet the following day at the Company's headquarters in
Rye, New York, to continue discussions.
 
     On May 6, 1998, Mr. Castellana met with Mr. Franklin and Ian Ashken, Chief
Financial Officer of the Company, at the Company's offices in Rye, New York. No
formal proposals regarding any business combination transaction were made, but
the parties agreed that Mr. Franklin should meet with Gregory Summe, the newly
appointed President and Chief Operating Officer of the Parent at a mutually
convenient date and site in the near future.
 
     On June 8, 1998, Mr. Franklin had dinner with Messrs. Summe and Castellana
in Boston, Massachusetts, where Mr. Summe outlined the Parent's strategy for its
Optoelectronic Business Unit and Mr. Summe advised Mr. Franklin that the Parent
was interested in augmenting its Optoelectronic Business Unit. Mr. Summe asked
Mr. Franklin if he would consider a possible combination of the Company with the
Parent's Optoelectronic Business Unit. Mr. Franklin advised that the Company
would consider such a possibility.
 
                                       16
<PAGE>   19
 
     On June 9, 1998, the parties executed a mutual confidentiality agreement
and agreed to exchange information. However, very limited information was
exchanged and there were no substantive contacts between the companies during
the summer of 1998.
 
     In early September, 1998, Mr. Castellana called Mr. Franklin to schedule a
further meeting. On September 9, 1998, Mr. Castellana and Stephen P. DeFalco,
the Parent's Vice President of Strategic Planning and Business Development, met
at the Company's offices with Messrs. Franklin and Ashken and with Richard
Capra, the Company's Chief Executive Officer, at which they reviewed the
Company's summary financial data and business strategy. At the end of the
meeting, Mr. Castellana advised Mr. Franklin that the Parent would review the
information and get back to him.
 
     On September 14, 1998, Mr. Summe called Mr. Franklin in the United Kingdom
to express the Parent's interest in proposing an acquisition transaction. The
possible structure and pricing of such an acquisition were not determined;
however, Mr. Franklin agreed on behalf of the Company to consider such a
possibility and to arrange for the Parent's representatives to visit the Company
sites upon Mr. Franklin's return to the United States.
 
     On September 29 and October 1, 1998, representatives of the Parent visited
the facilities of the Company's U.S. business operations.
 
     On October 7, 1998, Messrs. Franklin and Ashken met with members of the
Parent's management at the Parent's headquarters. Following a general discussion
of the strategic fit of the two companies, Mr. Summe expressed the Parent's
interest in making an all cash offer for the Company in a price range of
$7.50-$8.00 per share; however, no formal proposal was made.
 
     On October 9, 1998, Mr. Summe called Mr. Franklin and expressed the
Parent's willingness to make an all cash offer for all outstanding shares of the
Company at a price of $7.75 per share, subject to, among other things,
satisfactory completion of the Parent's due diligence investigation and entering
into a mutually satisfactory merger agreement. Mr. Franklin stated that such
price was within the range of valuation that he was willing to present to the
Company's Board. Mr. Franklin agreed to authorize the Parent to commence its due
diligence investigation at the Company's headquarters.
 
     On October 12, 1998, representatives of the Parent, including its internal
and outside counsel, and tax and accounting advisors, commenced their due
diligence review of the Company.
 
     On October 15, 1998, the Parent's counsel delivered a first draft of the
proposed Merger Agreement to the Company and its counsel. During the next week,
the Parent and the Company and their respective counsel proceeded with intensive
negotiations of the terms of the Merger Agreement and Messrs. Franklin and
Ashken, on behalf of themselves and Mr. Capra and George B. Clairmont, a
director of the Company, discussed the terms of a Stockholders' Agreement
requested by the Parent.
 
     On October 20, 1998, Mr. Summe called Mr. Franklin to confirm that $7.75
per Share was the highest price the Parent could offer for the Company. Mr.
Franklin stated that he would present the offer to the Company's Board for its
consideration at its meeting which was scheduled for the next day, subject to
Raymond James confirming that such price was fair to the Company and its
stockholders (other than the Parent and its affiliates) from a financial point
of view. Representatives of the Parent, the Company, and the stockholder parties
to the Stockholders' Agreement, continued to negotiate the definitive terms of
the Merger Agreement and the Stockholders' Agreement, which were finalized on
October 21, 1998.
 
     On October 21, 1998, the Board of Directors of the Parent held a meeting at
which they approved the Merger Agreement and the transactions contemplated
thereby. In the evening on October 21, 1998, the Merger Agreement and the
Stockholders' Agreement were executed and delivered by the parties thereto.
Shortly thereafter, the Parent and the Company jointly announced that the Merger
Agreement had been signed and Purchaser's intention to commence the Offer.
 
     On October 27, 1998, the Purchaser commenced the Offer.

11.  PURPOSE OF THE OFFER; THE MERGER AGREEMENT; THE STOCKHOLDERS' AGREEMENT;
     PLANS FOR THE COMPANY AFTER THE MERGER; SEC REGULATIONS; APPRAISAL RIGHTS
 
PURPOSE OF THE OFFER
 
     The purpose of the Offer is to enable the Parent, through its wholly owned
subsidiary, to acquire control of, and the entire equity interest in, the
Company. Following the Offer, the Purchaser and the Parent intend to acquire any
remaining equity interests in the Company not acquired in the Offer by
consummating the Merger. The purpose of the Merger is to effect a business
combination of the Purchaser and the Company. Following (i) the completion of
the Offer, (ii) approval of the Merger by the respective stockholders of the
Company and the Purchaser, to the extent necessary under the Delaware Law, and
(iii) the satisfaction of the other conditions described in the Merger
Agreement, the Company and the Purchaser intend to consummate the Merger;
provided, however, that without the consent of the Parent, the Merger will not
be consummated prior to January 11, 1999.
 
     The acquisition of the entire equity interest in the Company is structured
as a cash tender offer followed by a merger in order to expedite the opportunity
for the Parent and the Purchaser to obtain a controlling interest in the
Company.
 
THE MERGER AGREEMENT
 
     The following is a summary of the Merger Agreement, a copy of which is
filed as an exhibit to the Schedule 14D-1 and is incorporated herein by
reference. This summary does not purport to be complete and is qualified in its
entirety by reference to the Merger Agreement. Capitalized terms used herein and
not otherwise defined have the same meaning as in the Merger Agreement.
 
  The Offer
 
     The Merger Agreement provides for the commencement of the Offer within five
business days of the public announcement of the Purchaser's intention to make
the Offer. The obligation of the Purchaser to accept for payment any Shares
tendered is subject to the satisfaction of certain conditions (including the
Minimum Condition) which are described in Section 13.
 
  Approval of the Merger
 
     The Delaware Law requires, among other things, that the adoption of any
plan of merger or consolidation of the Company must be approved and found
advisable by the Board of Directors and generally by the holders of a majority
of the Company's outstanding voting securities. The Board of Directors of the
Company has approved the Offer, the Merger and the Merger Agreement, and the
transactions contemplated thereby, and, solely for the purpose of satisfying the
requirements of Section 203 of the Delaware Law, the Stockholders' Agreement and
the transactions contemplated thereby; consequently, the only additional action
of the Company that may be necessary to effect the Merger is approval by the
Company's stockholders if the "short-form" merger procedure described below is
not available. Under the Delaware Law, the affirmative vote of holders of a
majority of the outstanding Shares (including any Shares owned by the Purchaser)
is required to approve the Merger. Such approval may be obtained by written
consent in lieu of a stockholders' meeting. If the Purchaser acquires, through
the Offer or otherwise, voting power with respect to at least a majority of the
outstanding shares, it would have sufficient voting power to effect the Merger
without the vote of any other stockholder of the Company. The Delaware Law also
provides that if a parent company owns at least 90% of each class of stock of a
subsidiary, the parent company can effect a short-form merger with that
subsidiary without the action of any 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
outstanding Shares, the Purchaser could, and intends to, effect the Merger
without prior notice to, or any action by, any other stockholder of the Company.
 
                                       18
<PAGE>   21
 
  The Merger
 
     The Merger Agreement provides that as soon as practicable after the
satisfaction or waiver of certain conditions set forth in the Merger Agreement
(but in no event prior to January 11, 1999, unless so requested by the Parent),
subject to the terms and conditions thereof and in accordance with the Delaware
Law, the Purchaser shall be merged with and into the Company, the separate
existence of the Purchaser shall cease and the Company shall continue as the
Surviving Corporation. Upon the Effective Time of the Merger, (i) each Share
issued and outstanding immediately prior to the Effective Time (other than
Shares held by the Parent, the Purchaser or the Company or any direct or
indirect subsidiary of the Parent, the Purchaser or the Company and Shares held
by stockholders, if any, who are entitled to and who perfect their appraisal
rights (See "Appraisal Rights") under Section 262 of the Delaware Law) will be
cancelled and extinguished and be converted into and represent the right to
receive the Merger Consideration and (ii) each outstanding share of the
Purchaser's capital stock issued and outstanding immediately prior to the
Effective Date shall be converted into and become one validly issued, fully paid
and nonassessable share of the same class of capital stock of the Surviving
Corporation. As a result of the Merger, the Company will become a wholly owned
subsidiary of the Parent.
 
     The Merger Agreement provides that the Certificate of Incorporation and
By-Laws of the Purchaser as in effect immediately prior to the Effective Time
will become the Certificate of Incorporation and By-Laws of the Surviving
Corporation until thereafter amended as provided under the Delaware Law except
that the name of the Surviving Corporation will be "Lumen Technologies, Inc."
and the indemnification provisions set forth in the Certificate of Incorporation
and By-laws of the Surviving Corporation shall be restated to conform to the
indemnification provisions set forth in the Certificate of Incorporation and
Bylaws, respectively, of the Company. In addition, under the Merger Agreement,
the directors of the Purchaser immediately prior to the Effective Time will be
the initial directors of the Surviving Corporation following the Merger, and the
officers of the Company immediately prior to the Effective Time will be the
initial officers of the Surviving Corporation following the Merger, in each case
until their successors are elected and qualified.
 
  Designation of Directors
 
     The Merger Agreement provides that, promptly upon the acceptance for
payment of and payment by the Purchaser for any Shares pursuant to the Offer,
and from time to time thereafter as Shares are accepted for payment and paid for
by the Purchaser, the Purchaser shall be entitled to designate such number of
the Company's directors, rounded to the nearest whole number, as will give the
Purchaser representation on the Company's Board of Directors equal to the
greater of (i) a majority and (ii) the product of the total number of the
Company's directors (after giving effect to the directors elected in accordance
with this procedure) multiplied by the percentage that such number of Shares so
accepted for payment and paid for by the Purchaser bears to the number of Shares
outstanding, and the Company shall, at such time, take such actions as are
necessary to cause the Purchaser's designees to be so elected or appointed,
including increasing the size of the Company's Board of Directors or using its
best efforts to secure the resignations of incumbent directors or both;
provided, however, that, notwithstanding the Purchaser's right to designate
certain of the Company's directors as described above, until the Effective Time,
the Company's directors shall include at least three directors who were
directors on the date of the Merger Agreement (the "Independent Directors");
provided, further, that, if the number of Independent Directors shall be reduced
below three for any reason whatsoever, any remaining Independent Director shall
be entitled to designate a person to fill such vacancies and such person shall
be deemed to be an Independent Director or, if no Independent Directors then
remain, the other directors shall designate three persons to fill such vacancies
who shall not be designees, stockholders, directors, officers, employees or
affiliates of the Parent or the Purchaser, and such persons shall be deemed to
be Independent Directors.
 
     Notwithstanding anything in the Merger Agreement to the contrary, subject
to the terms of the Company's Certificate of Incorporation and Bylaws, in the
event that the Purchaser's designees are appointed or elected as the Company's
directors, after the acceptance for payment of Shares pursuant to the Offer and
prior to the Effective Time, the affirmative vote of a majority (or, if there
are only one or two Independent Directors, the single or unanimous vote, as the
case may be) of the Independent Directors (who shall act as an

                                       19
<PAGE>   22
 
independent committee of the Board of Directors for this purpose) shall be
required, and alone shall be sufficient, to (i) amend or terminate the Merger
Agreement by the Company, (ii) exercise or waive any of the Company's rights or
remedies under the Merger Agreement, (iii) extend the time for performance of
the Parent's and the Purchaser's respective obligations under the Merger
Agreement, or (iv) approve any other action by the Company that the Independent
Directors reasonably determine would materially adversely affect the interests
of the stockholders of the Company (other than the Parent, the Purchaser and
their affiliates) with respect to the transactions contemplated by the Merger
Agreement.

<PAGE>   23
 
          (iv) no preliminary or permanent injunction or other order, decree or
     ruling issued by a court of competent jurisdiction or by any Governmental
     Entity, nor any statute, rule, regulation or executive order promulgated or

     acquisition or holding by the Parent or its subsidiaries of the Shares or
     shares of common stock of the Surviving Corporation illegal or otherwise
     prevent the consummation of the Merger.
 
     In addition, the obligation of the Purchaser and the Parent to consummate
the Merger is subject to the further condition that at or prior to the Effective
Time, all governmental and third-party consents and approvals required to be
obtained by the Company to consummate the Merger shall have been obtained,
except for (a) consents required under the Company's credit facility with

consent or approval would not have a Material Adverse Effect.
 
  Acquisition Proposals
 
     The Company has agreed in the Merger Agreement that it shall not, and shall
not authorize or permit any of its subsidiaries, or any of its or their
officers, directors, employees, representatives, agents or affiliates, including
any investment banker, attorney or accountant retained by the Company or any of
its subsidiaries, to, directly or indirectly, (i) solicit, initiate or encourage
(including by way of furnishing information), or take any other action to
facilitate, any inquiries or the making of any proposal or offer that
constitutes, or may reasonably be expected to lead to, any Acquisition Proposal
or (ii) enter into, maintain, continue or otherwise participate in any
discussions or negotiations regarding any Acquisition Proposal with any person,
entity or group other than the Parent, the Purchaser or their respective direct
or indirect subsidiaries or affiliates (a "Third Party"). Notwithstanding the
foregoing, the Company, its subsidiaries, and their respective officers,
directors, employees, representatives, agents and affiliates, including any
investment banker, attorney or accountant retained by the Company or any of its
subsidiaries, may (i), in the case of a Qualified Acquisition Proposal only,
furnish or cause to be furnished information concerning the Company's business,
properties or assets to a Third Party (subject to such Third Party executing a
confidentiality agreement on terms no less favorable to the Company than those
in the confidentiality agreement previously entered into by the Parent and the
Company), (ii) in the case of a Qualified Acquisition Proposal only, enter into,
participate in, conduct or engage in discussions or negotiations with such Third
Party, (iii) to the extent that the Board of Directors of the Company is
required by its fiduciary duties, as advised by counsel, take any position with
respect to an Acquisition Proposal in accordance with Rules 14a-9 and 14e-2
promulgated under the Exchange Act, and (iv) in the case of a Qualified
Acquisition Proposal only and only prior to the acceptance for payment of that
number of Shares tendered pursuant to the Offer sufficient to satisfy the
Minimum Condition and in compliance with the provisions of the Merger Agreement,
enter into an agreement to consummate a Qualified Acquisition Proposal.
 
     "Acquisition Proposal" means an inquiry, offer or proposal regarding any of
the following (other than the transactions contemplated by the Merger Agreement)
involving the Company or its subsidiaries: (i) any merger, reorganization,
consolidation, share exchange, recapitalization, business combination,
liquidation, dissolution or other similar transaction involving, or any sale,
lease, exchange, mortgage, pledge, transfer or other disposition of, all or any
significant portion of the assets or 25% or more of the equity securities of,
the Company or any of its subsidiaries, in a single transaction or series of
related transactions; (ii) any tender offer or exchange offer for 25% or more of
the outstanding shares of capital stock of the Company or the filing of a
registration statement under the Securities Act of 1933, as amended (the
"Securities Act"), in connection therewith; or (iii) any public announcement of
a proposal, plan or intention to do any of the foregoing or any agreement to
engage in any of the foregoing.
 
     "Qualified Acquisition Proposal" means an unsolicited, bona fide, written
Acquisition Proposal made by a Third Party that the Board of Directors of the
Company determines in its good faith judgment to be more favorable to the
Company's stockholders than the Offer and the Merger (based on the opinion, with
only customary qualifications, of the Company's independent financial advisor
that the value of the consideration to the Company's stockholders provided for
in such proposal exceeds the value of the consideration to the Company's
stockholders provided for in the Merger Agreement by the Offer and the Merger)
and for which

                                       21
<PAGE>   24
 
financing, to the extent required, is then committed or which, in the good faith
judgment of the Board of Directors of the Company (based on the advice of the
Company's independent financial advisor), is reasonably capable of being
obtained by such Third Party and which Acquisition Proposal, in the good faith
judgment of the Board of Directors of the Company, is likely to be consummated.
 
     Such provisions do not prohibit the Company from making such disclosure to
stockholders that, in the judgment of the Board of Directors of the Company, as
advised by counsel, may be required by law or necessary to discharge any
fiduciary duty imposed thereby.
 
     Pursuant to the Merger Agreement, the Company must immediately notify the
Parent of, and disclose to the Parent all details of, (i) any Acquisition
Proposal it receives, (ii) any written indications that any person is interested
in making an Acquisition Proposal or (iii) the initiation and status of
discussions or negotiations relating to any Acquisition Proposal (it being
understood that pursuant to the Merger Agreement any Acquisition Proposal must
be a Qualified Acquisition Proposal). In the event that the Company furnishes
any nonpublic information to any party other than the Parent, it shall
simultaneously provide the Parent with copies of or access to all such
information.
 
     In addition, the Company may not enter into any agreement with any Third
Party in connection with a Qualified Acquisition Proposal unless (i) at least
three business days prior thereto the Company shall have provided the Parent and
the Purchaser a copy of the Qualified Acquisition Proposal, (ii) within such
three business day period, the Parent and the Purchaser do not make an offer
which, in the good faith judgment of the Board of Directors of the Company
(based on the advice of the Company's independent financial advisor) is at least
as favorable to the Company's stockholders as such Acquisition Proposal, (iii)
the Company shall have terminated the Merger Agreement in accordance with its
terms and (iv) prior thereto the Company shall have paid the fees specified in
the Merger Agreement, and shall have deposited $500,000 in trust with a
Qualified Commercial Bank for the payment of the expenses specified in the
Merger Agreement.

     termination of such Company Options;
 
          (ii) issue, deliver, sell, pledge or otherwise dispose of or encumber,

  Indemnification and Insurance
 
     Through the third anniversary of the Effective Time, the Parent will
maintain in effect for the benefit of the directors and officers of the Company
as of the date of the Merger Agreement, directors' and officers' liability
insurance policies with coverages and other terms substantially as favorable to
such directors and officers as is in effect on the date of the Merger Agreement.
In no event, however, will the Parent be required to expend more than an amount
per year equal to 150% of the current annual premium paid by the Company as of
the date of the Merger Agreement for such insurance coverage.
 
     The Parent and the Purchaser have agreed in the Merger Agreement that all
rights to indemnification, limitation of liability, exculpation, advancement of
expenses and any and all similar rights existing on the date of the Merger
Agreement in favor of present or former employees, agents, directors or officers
of the Company and its subsidiaries as provided in their respective charter or
bylaws (each as in effect on the date of the Merger Agreement) shall survive the
Offer and the Merger and shall continue in full force and effect for a period of
six years from the Effective Time; provided, however, that in the event any
claim or claims are asserted or made within such six year period, all rights to
indemnification in respect to any such claim or claims shall continue until the
disposition of such claims.
 
     The Merger Agreement also provides that the Company shall, to the fullest
extent permitted under applicable law and regardless of whether the Merger
becomes effective, indemnify and hold harmless, and, after the Effective Time,
the Surviving Corporation shall, to the fullest extent permitted under
applicable law, indemnify and hold harmless, each present and former director,
officer, employee, fiduciary and agent of the Company and each Subsidiary and
their respective heirs, executors, administrators, personal representatives or
assigns (collectively, the "Indemnified Parties") against all costs and expenses
(including attorneys' fees), judgments, fines, losses, claims, damages,
liabilities and settlement amounts paid in connection with any claim, action,
suit, proceeding or investigation (whether arising before or after the Effective
Time), whether civil, criminal, administrative or investigative (a
"Proceeding"), arising out of or pertaining to any action or omission in their
capacity as an officer, director, employee, fiduciary or agent, whether
occurring before or after the Effective Time, to the same extent as provided in
the Company's Certificate of Incorporation or By-laws as in effect on the date
of the Merger Agreement, in each case for a period of six years after the date
of the Merger Agreement. In the event that any claim for indemnification is
asserted or made within such six-year period, all rights to indemnification in
respect of such claim shall continue until the disposition of such claim.
 
                                       24
<PAGE>   27
 
     Each Indemnified Party shall give written notice to the Company or the
Surviving Corporation, as the case may be (the "Indemnifying Party") promptly
after such Indemnified Party has actual knowledge of any claim as to which
indemnity may be sought, and shall permit the Indemnifying Party to assume the
defense of any Proceeding resulting therefrom; provided, that counsel for the
Indemnifying Party, who shall conduct the defense of such Proceeding, shall be
approved by the Indemnified Party (whose approval shall not be unreasonably
withheld, conditioned or delayed); and, provided, further, that the failure of
any Indemnified Party to give notice as provided in the Merger Agreement shall
not relieve the Indemnifying Party of its obligations under the Merger Agreement
unless and to the extent that the Indemnifying Party is adversely affected by
such failure. The Indemnified Party may participate in such defense at such
party's expense; provided, however, that the Indemnifying Party shall pay such
expense if representation of such Indemnified Party by the counsel retained by
the Indemnifying Party would be inappropriate due to actual or potential
differing interests between the Indemnified Party and any other party
represented by such counsel in such Proceeding. In the event that the
Indemnifying Party does not assume the defense pursuant to the terms of the
Merger Agreement of any Proceeding of which the Indemnifying Party receives
notice, any expenses incurred by the Indemnified Party in defending such
Proceeding shall be paid by the Indemnifying Party in advance of the final
disposition of such matter, provided, however, that the payment of such expenses
incurred by the Indemnified Party in advance of the final disposition of such
matter shall be made only upon receipt of an undertaking by or on behalf of the
Indemnified Party to repay all amounts so advanced in the event that it shall
ultimately be determined that the Indemnified Party is not entitled to be
indemnified by the Indemnifying Party in accordance with the Merger Agreement.
The Indemnified Party shall cooperate with the Indemnifying Party and provide
access to all documents necessary or beneficial to the defense of any
Proceeding. Neither the Company nor the Surviving Corporation shall be liable
for any settlement of any Proceeding effected without its written consent.
 
     The Merger Agreement also provides that if the Company or the Surviving
Corporation or any of their respective successors or assigns consolidates with
or merges into any other person and shall not be the continuing or surviving
corporation or entity of such consolidation or merger, then, and in each such
case, the Parent will either guarantee the indemnification obligations described
above or will make or cause to be made proper provision so that the successors
and assigns of the Company or the Surviving Corporation, as the case may be,
assume the indemnification obligations described above.
 
  Fees and Expenses
 
     The Merger Agreement provides that, except as otherwise provided in the
Merger Agreement, each party thereto shall bear all of the fees and expenses
incurred by it in connection with the negotiation and performance of the Merger
Agreement and no party to the Merger Agreement may recover any such fees and
expenses from another party upon termination of the Merger Agreement.
 
     If, however, (i) the Company's Board of Directors, whether or not in the
exercise of its fiduciary or other legal duties, either (A) shall have failed to
approve or recommend, or shall have withdrawn or adversely modified or taken a
public position materially inconsistent with its approval or recommendation of,
the Offer, the Merger or the Merger Agreement and the Parent shall have elected
to terminate the Merger Agreement as a result thereof, or (B) take any action
(other than as expressly permitted under the terms of the Merger Agreement) with
respect to any Qualified Acquisition Proposal other than to recommend rejection
of the Qualified Acquisition Proposal (including taking a position of neutrality
or failing to take any position within ten business days after the making or
commencement of a Qualified Acquisition Proposal); or (ii) prior to the final
expiration of the Offer, an Acquisition Proposal shall have become publicly
known and the Merger Agreement is terminated (other than as a result of a
material breach of the Merger Agreement by the Parent or the Purchaser) and,
within 12 months after such termination, (A) the Company enters into a merger or
other agreement that contemplates the consummation of an Acquisition Proposal at
a price equal to or greater than the aggregate consideration payable for Shares
pursuant to the Offer and the Merger or (B) the holders of Shares become
entitled to receive consideration per Share greater than the Merger
Consideration in a transaction or series of transactions in connection with an
Acquisition Proposal or (iii) the Company elects to terminate the Merger
Agreement in order to enter into an agreement with a Third Party to consummate a
 
                                       25
<PAGE>   28
 
Qualified Acquisition Proposal, then, in each such case, the Company shall pay
the Parent $7,450,000 in cash and an amount equal to the reasonable
out-of-pocket expenses incurred by the Parent and the Purchaser in connection
with the evaluation, negotiation, implementation and consummation of the
transactions contemplated by the Merger Agreement (including fees and expenses
of legal counsel, solicitors, accountants, printers and financial advisors and
investment bankers); provided, however, that, in no event shall the amount of
such expenses exceed $500,000. The Company is also required to reimburse the
Parent for up to $500,000 in expenses in certain circumstances if the Parent
terminates the Merger Agreement because of a failure by the Company to perform
in any respect any of its material obligations under the Merger Agreement.
 
  Termination
 
     The Merger Agreement may be terminated at any time prior to the Effective
Time (whether prior to or after approval by the stockholders of the Company), as
follows:
 
     (a) by the mutual written consent of the Boards of Directors of the Parent
and the Company; or
 
     (b) by the Company:
 
          (i) if neither the Parent nor any of its subsidiaries or affiliates
     shall have (A) publicly announced its intention to make the Offer no later
     than the first business day following the date of the Merger Agreement or
     (B) commenced the Offer within five business days of such announcement
     unless such failure to commence is due to a material breach of the Merger
     Agreement by the Company; or
 
          (ii) if, in the absence of any material breach of the Merger Agreement
     by the Company, (A) the Offer shall have been terminated or the Purchaser
     shall have allowed the Offer to expire without the purchase of such number
     of Shares thereunder as satisfies the Minimum Condition; or (B) neither the
     Parent nor any of its subsidiaries or affiliates shall have paid for all
     Shares validly tendered pursuant to the Offer and not withdrawn within 60
     days after the commencement of the Offer; or
 
          (iii) if the Effective Time shall not have occurred on or before March
     31, 1999 due to a failure of any of the conditions to the obligation of the
     Company to effect the Merger set forth in the Merger Agreement; or
 
          (iv) if, prior to the purchase of any Shares pursuant to the Offer,
     the Parent or the Purchaser fails to perform any of their respective
     obligations under the Merger Agreement and such failure or nonperformance
     materially impairs the Parent's and the Purchaser's ability to consummate
     the Offer or the Merger; or
 
          (v) if the Company has, in accordance with the terms of the Merger
     Agreement, entered into an agreement with a Third Party to consummate a
     Qualified Acquisition Proposal; or
 
          (vi) if there shall have been a breach of any material representation
     and warranty of the Purchaser or the Parent set forth in the Merger
     Agreement prior to the expiration or termination of the Offer, which breach
     is not cured within five days following written notice thereof by the
     Company to the Purchaser and the Parent; or
 
     (c) by the Parent:
 
          (i) if, due to an occurrence that would result in a failure to satisfy
     any of the conditions to the Offer described in the Merger Agreement, the
     Parent or any of its subsidiaries or affiliates shall have (A) failed to
     commence the Offer within five business days of the date on which the
     Purchaser's intention to make the Offer is publicly announced; (B)
     terminated the Offer without the purchase of any Shares thereunder; or (C)
     failed to pay for Shares pursuant to the Offer within 60 days after the
     commencement of the Offer; or
 
          (ii) if the Effective Time shall not have occurred on or before March
     31, 1999 due to a failure of any of the conditions to the obligations of
     the Parent and the Purchaser to effect the Merger set forth in the Merger
     Agreement otherwise than as a result of a material breach or default by the
     Parent or Purchaser under the Merger Agreement; or

                                       26
<PAGE>   29
 
          (iii) if the Company's Board of Directors, whether or not in the
     exercise of their fiduciary or other legal duties, either (A) shall have
     failed to approve or recommend, or shall have withdrawn or adversely
     modified or taken a public position materially inconsistent with its
     approval or recommendation of, the Offer, the Merger or the Merger
     Agreement or (B) takes any action (other than as expressly permitted under
     the Merger Agreement) with respect to any Qualified Acquisition Proposal
     other than to recommend rejection of the Qualified Acquisition Proposal
     (including taking a position of neutrality or failing to take any position
     within 10 business days after the making or commencement of a Qualified
     Acquisition Proposal); or
 
          (iv) if, prior to the purchase of any Shares pursuant to the Offer,
     the Company fails to perform in any respect any of its material obligations
     under the Merger Agreement, which failure to perform (other than a failure
     to perform an obligation described under the heading "Acquisition
     Proposals," as to which there will be no cure period) is not cured within
     five days following notice thereof by the Parent to the Company; or
 
     (d) by either the Company or the Parent, if any Governmental Entity shall
have issued an order, decree or ruling or taken any other action permanently
enjoining, restraining or otherwise prohibiting the acceptance for payment of,
or payment for, Shares pursuant to the Offer or the Merger and such order,
decree or ruling or other action shall have become final and nonappealable;
provided, however, that the party seeking to terminate the Merger Agreement
pursuant to this provision shall have performed its obligations under the Merger
Agreement to use reasonable efforts to avoid such event.
 
  Amendment
 
     Subject to the amendment provision described above under "-- Designation of
Directors," the Merger Agreement may not be amended except by action of the
Boards of Directors of each of the parties to the Merger Agreement, set forth in
an instrument in writing signed on behalf of each of the parties; provided,
however, that if the Merger Agreement and the Merger are subject to stockholder
approval, then after such approval, no amendment shall be made which by law
requires further approval by such stockholders without obtaining such further
approval.
 
  Waiver
 
     At any time prior to the Effective Time, whether before or after any
meeting of the stockholders of the Company to vote on the Merger, any party to
the Merger Agreement, subject to the waiver provisions described above under
"-- Designation of Directors," by action taken by its Board of Directors,
subject to the provisions of the Merger Agreement, may (i) extend the time for
the performance of any of the obligations or other acts of any other party to
the Merger Agreement or (ii) waive compliance with any of the agreements of any
other party or with any conditions to its own obligations, provided, however,
that if the Merger Agreement and the Merger are subject to stockholder approval
then, after such approval, no waiver shall be made which by law requires further
approval by such stockholders without obtaining such further approval. Any
agreement on the part of a party to the Merger Agreement to any such extension
or waiver shall be valid only if set forth in an instrument in writing signed on
behalf of such party by a duly authorized officer.
 
  Guarantee
 
     Pursuant to the Merger Agreement, the Parent has unconditionally and
irrevocably guaranteed the Purchaser's obligations under the Merger Agreement
and has agreed to be liable for any breach of the Merger Agreement by the
Purchaser.
 
  Treatment of Options
 
     Pursuant to terms of the Merger Agreement, as of the Effective Time, the
Parent shall assume the Option Plan and the obligations of the Company
thereunder and all of the Company Options which are then outstanding shall be
assumed by the Parent. Immediately after the Effective Time, each Company Option
shall constitute an option to acquire, on the same terms and conditions as were
applicable to Company Option
                                       27
<PAGE>   30
 
immediately prior to the Effective Time, such number of shares of common stock,
par value $1.00 per share, of the Parent (the "Parent Common Stock") as is equal
to the number of Shares subject to such Company Option immediately prior to the
Effective Time multiplied by a fraction, the numerator of which is the Merger
Consideration and the denominator of which is the average closing price of the
Parent Common Stock on the NYSE, as reported in The Wall Street Journal (or if
not so reported in another authoritative source), for the ten trading days
ending on the date of the expiration of the Offer (with any fraction resulting
from such multiplication to be rounded down to the nearest whole number). The
exercise price per share of each such assumed Company Option shall be equal to
the per share exercise price of such Company Option immediately prior to the
Effective Time multiplied by a fraction, the numerator of which is the average
closing price of the Parent Common Stock on the NYSE, as reported in The Wall
Street Journal (or if not so reported in another authoritative source), for the
ten trading days ending on the date of the expiration of the Offer and the
denominator of which is the Merger Consideration (with any fraction resulting
from such multiplication to be rounded up to the nearest whole cent). Except as
otherwise provided in the Merger Agreement, the term, exercisability, vesting
schedule, status and all of the other terms of the Company Options shall
otherwise remain unchanged.
 
     As soon as practicable after the Effective Time, the Parent shall, with
respect to all shares of Parent Common Stock subject to such Company Options,
(i) either (x) file a Registration Statement on Form S-8 (or any successor form)
under the Securities Act or (y) file any necessary amendments to the Company's
previously filed Registration Statements on Form S-8 in order that the Parent
will be deemed a "successor registrant" thereunder, and, in either event, shall
use all reasonable efforts to maintain the effectiveness of such registration
statement for so long as such Company Options remain outstanding, and (ii) take
all actions necessary to have such shares of Parent Common Stock approved for
listing on the NYSE, subject to official notice of issuance.
 
     Notwithstanding the foregoing, pursuant to the terms of the Merger
Agreement and the Option Plan, the Compensation Committee of the Board of
Directors has resolved to vest all Company Options upon the closing of the Offer
and to cash out the Company Options of holders requesting the Company to do so.
Holders of Company Options who request that such Company Options be cashed out
shall be paid an amount equal to the difference between the price per Share to
be paid in the Offer and the exercise price and such Company Options shall
thereupon be cancelled. Such payment shall be made within one business day of
the closing of the Offer.
 
  Other Obligations
 
     The Merger Agreement provides for the Parent to cause the Company to pay,
in accordance with their respective terms, certain bonuses under the Company's
bonus plan for 1998, accrued vacation pay and other benefits to certain
employees of the Company, including Messrs. Franklin and Ashken. In addition,
the Merger Agreement provides that the Parent shall cause the Company to make
severance payments in the amount of $530,000 and $424,000 to each of Messrs.
Franklin and Ashken, respectively, in accordance with the terms of their
respective employment agreements. The Parent has also agreed to continue paying
all premiums on split dollar life insurance policies for the benefit of Messrs.
Franklin and Ashken for the remainder of the terms of such policies.

     The following is a summary of the Stockholders' Agreement, a copy of which

<PAGE>   31
 
the Management Stockholders agreed: (i) to validly tender, and not to withdraw,
pursuant to and in accordance with the terms of the Offer, (x) within five
business days after the commencement of the Offer, all Shares owned by such
Management Stockholder as of the date of the Stockholders' Agreement, and (y)
prior to the scheduled expiration of the Offer, any additional Shares acquired
after the date of the Stockholders' Agreement by such Management Stockholder;
(ii) to vote all Shares that such Management Stockholder is entitled to vote to
approve and adopt the Merger Agreement, the Merger and all agreements related to
the Merger and any actions related thereto; (iii) not to vote in favor of any
Acquisition Proposal, reorganization, recapitalization, liquidation or winding
up of the Company or any other extraordinary transaction involving the Company,
or any corporate actions the consummation of which would frustrate the purposes,
or prevent or delay the consummation, of the transactions contemplated by the
Merger Agreement; (iv) revoke any and all previous proxies granted with respect
to such Management Stockholder's Shares, and to appoint the Purchaser as such
Management Stockholder's attorney-in-fact and proxy to vote the Shares in such
manner and upon such matters as the Purchaser shall, in the Purchaser's sole
discretion, deem proper; (v) not to grant any proxies or enter into any voting
trust or other arrangement with respect to the voting of any Shares; and (vi)
not to sell, assign, transfer, encumber or otherwise dispose of any Shares, or
enter into any contract, option or other arrangement or understanding with
respect to the sale, assignment, transfer, encumbrance or other disposition of,
any Shares, except for transfers by gift of options to purchase Shares to any
charitable organization, with the prior written consent of the Purchaser.
 
     The proxy grant pursuant to the Stockholders' Agreement shall be revoked
upon termination of the Stockholders' Agreement in accordance with its terms.
The Stockholders' Agreement, and the Management Stockholders' obligations
thereunder, shall expire on the first to occur of (i) the Effective Time or (ii)
the termination of the Merger Agreement in accordance with its terms. In
addition, the Stockholders' Agreement may be terminated by the Purchaser and the
Parent upon written notice to the Management Stockholders.
 
PLANS FOR THE COMPANY AFTER THE MERGER
 
     Except as described in this Offer to Purchase, based on its current
knowledge of the Company, the Purchaser has no present plans or proposals which
relate to or would result in any extraordinary corporate transaction, such as a
merger, reorganization, liquidation, or sale or transfer of a material amount of
assets involving the Company or any of its subsidiaries, or any material changes
in the Company's capitalization, dividend policy, corporate structure or
business or the composition of its board of directors or management. However,
the Purchaser is continuing its review of the Company and its assets, corporate
structure, capitalization, operations, properties, policies, management and
personnel. After the completion of such review (subject to the provisions of the
Merger Agreement), the Purchaser may propose or develop alternative plans or
proposals, including mergers, transfers of a material amount of assets or other
transactions or changes of the nature described above. The Purchaser reserves
the right, subject to the terms and conditions of the Merger Agreement, to
effect any such plans and proposals.
 
     The consummation of the Offer will constitute a "change of control" with
respect to the Convertible Notes. As a result, the Company may be required to
offer to repurchase the Convertible Notes from all holders thereof at a purchase
price of 101% of outstanding principal plus accrued and unpaid interest. As of
September 30, 1998, approximately $15 million principal amount of Convertible
Notes was outstanding. In addition, as a result of the consummation of the
Offer, all amounts outstanding under the Company's credit facility with
NationsBank, National Association may become due and payable. As of September
30, 1998, approximately $53 million was outstanding under such credit facility.
If an extension of this facility is not negotiated, the Parent expects that the
Company will refinance the indebtedness with a new loan facility.
 
SEC REGULATIONS
 
     The SEC has adopted Rule 13e-3 under the Exchange Act which is applicable
to certain "going private" transactions. The Purchaser believes that Rule 13e-3
will not be applicable to the Merger if it is consummated within one year after
expiration or termination of the Offer and the price paid in the Merger is not
less than the price paid to purchase shares pursuant to the Offer. However, if
the Purchaser is deemed to have acquired control of the Company pursuant to the
Offer and if the Merger is consummated more than one year after

                                       29
<PAGE>   32
 
completion of the Offer or an alternative acquisition transaction is effected
whereby stockholders of the Company receive consideration less than that paid
pursuant to the Offer, in either case at a time when the Shares are still
registered under the Exchange Act, the Purchaser may be required to comply with
Rule 13e-3. If applicable, Rule 13e-3 would require, among other things, that
certain financial information concerning the Company and certain information
relating to the fairness of the Merger and the consideration offered to minority
stockholders be filed with the SEC and distributed to minority stockholders
prior to the consummation of the Merger.
 
APPRAISAL RIGHTS
 
     Company stockholders do not have appraisal rights as a result of the Offer.
However, in connection with the Merger, Company stockholders have the right to
demand an appraisal of the fair value of their Shares in accordance with the
provisions of Section 262 of the Delaware Law ("Section 262"), which sets forth
the rights and obligations of Company stockholders demanding an appraisal and
the procedures to be followed. Failure to follow any Section 262 procedures may
result in termination or waiver of appraisal rights under Section 262.
 
     Any Company stockholder who desires to exercise his appraisal rights in
connection with the Merger should review carefully Section 262 and is urged to
consult his legal advisor before electing or attempting to exercise such rights.
Stockholders considering seeking appraisal in connection with the Merger should
bear in mind that the fair value of their Shares determined under Section 262
could be more, the same, or less than the Merger Consideration.
 
12.  CERTAIN EFFECTS OF THE OFFER ON THE MARKET FOR SHARES; NYSE LISTING;
     EXCHANGE ACT REGISTRATION; MARGIN REGULATIONS
 
     Possible Effect of the Offer on the Market for Shares.  The purchase of
Shares pursuant to the Offer will reduce the number of Shares that might
otherwise trade publicly and is likely to reduce the number of holders of
Shares. This could adversely affect the liquidity and market value of the
remaining Shares held by the public.
 
     NYSE Listing.  Upon consummation of the Offer, the Shares may no longer
meet the standards for continued listing on the NYSE. According to the NYSE's
published guidelines, the NYSE would consider delisting the Shares if, among
other things, the number of publicly held Shares falls below 600,000, the number
of holders of Shares falls below 400 or the aggregate market value of such
publicly held Shares falls below $8,000,000. Shares held directly or indirectly
by an officer or director of the Company, or their immediate families, or by a
beneficial owner of more than 10% of the Shares will ordinarily not be
considered as being publicly held for purposes of these standards. In the event
the Shares are 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 exchanges, through
the Nasdaq Stock Market or other sources. However, the extent of the public
market for the Shares and the availability of such quotations would depend upon
the number of holders and/or the aggregate market value of such Shares remaining
at such time, the interest in maintaining a market in such Shares on the part of
securities firms, the possible termination of registration of such Shares under
the Exchange Act, as described herein, and other factors.
 
     Exchange Act Registration.  The Shares are currently registered under the
Exchange Act. The purchase of Shares pursuant to the Offer or following
consummation of the Offer may result in the Shares becoming eligible for
deregistration under the Exchange Act. Registration of the Shares may be
terminated upon application of 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 the Shares. The termination of the registration of the Shares under
the Exchange Act, assuming there are no other securities of the Company subject
to registration, would substantially reduce the information required to be
furnished by the Company to holders of the Shares and would make certain
provisions of the Exchange Act, such as the short-swing profit recovery
provisions of Section 16(b), the requirement of furnishing a proxy or
information statement pursuant to Sections 14(a) and 14(c) and the requirements
of Rule 13e-3 under the Exchange Act with respect to "going private"
 
                                       30
<PAGE>   33
 
transactions, no longer applicable to the Shares. Furthermore, "affiliates" of
the Company and persons holding "restricted securities" of the Company may be
deprived of the ability to dispose of the securities pursuant to Rule 144 under
the Securities Act. If registration of the Shares under the Exchange Act were
terminated, the Shares would no longer be "margin securities". The Purchaser
presently intends to seek to cause the Company to terminate the registration of
the Shares under the Exchange Act as soon after the consummation of the Offer or
Merger as the requirements for termination of registration are met.
 
     Margin Regulations.  The Shares are currently "margin securities" under the
rules of the Board of Governors of the Federal Reserve System (the "Federal
Reserve Board"), which has 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 this Offer or
following consummation of the Merger, 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."
 
13.  CERTAIN CONDITIONS OF THE OFFER
 
     Notwithstanding any other provisions of the Offer or the Merger Agreement,

above; or
 
     (f) the Company shall have failed to perform any material obligation or to

<PAGE>   35
 
     (h) any of the representations and warranties of the Company set forth in
the Merger Agreement that are qualified as to materiality shall have been
breached or not be true and correct in any respect or any such representations
and warranties that are not so qualified shall have been breached or not be true

     (i) except as to matters which are attributable to the announcement or

Parent or the Purchaser, in whole or in part, at any time and from time to time,
in their sole discretion. The failure by the Parent or the Purchaser at any time
to exercise any of the foregoing rights will not be deemed a waiver of any such
right, the waiver of any such right with respect to particular facts and
circumstances shall not be deemed a waiver with respect to any other facts and
circumstances and each such right will be deemed an ongoing right that may be
asserted at any time and from time to time.
 
14.  CERTAIN LEGAL MATTERS; REGULATORY APPROVALS
 
     General.  Based on a review of publicly available Commission filings by the
Company and other publicly available information concerning the Company and
representations of the Company in the Merger Agreement, except as described
below, neither the Parent nor the Purchaser is aware of any license or
regulatory permit that appears to be material to the business of the Company and
its subsidiaries that might be adversely affected by the Purchaser's acquisition
of Shares as contemplated herein.
 
     Except as described in this Section 14, neither the Parent nor the
Purchaser is aware of any other material filing, approval or other action by any
federal or state governmental or administrative authority that would be required
for the acquisition of Shares by the Purchaser as contemplated herein. Should
any such other approval or action be required, it is currently contemplated that
such approval or other action would be sought. Except as described below under
"Antitrust", there is, however, no present intention to delay the purchase of
Shares tendered pursuant to the Offer pending the outcome of any such other
approval or action. There can be no assurance that any such other approval or
action, if needed, would be obtained without substantial conditions or that
adverse consequences might not result to the Purchaser's or the Company's
business in the event that such other approvals were not obtained or such other
actions were not taken. The Purchaser's obligation under the Offer to accept for
payment and pay for Shares is subject to certain conditions, including
conditions relating to the legal matters discussed in this Section 14. See
Section 13.
 
     Antitrust.  Under the HSR Act and the rules promulgated thereunder by the
FTC, certain acquisition transactions may not be consummated unless certain
information has been furnished to the FTC and the Antitrust Division and certain
waiting period requirements have been satisfied. The acquisition of Shares
pursuant to the Offer is subject to such requirements. See Section 2.
 
     On October 22, 1998, the Parent filed with the Antitrust Division and the
FTC a Premerger Notification and Report Form, in connection with the purchase of
Shares pursuant to the Offer. Under the provisions of the HSR Act applicable to
the Offer, the purchase of Shares pursuant to the Offer may not be consummated
until
 
                                       33
<PAGE>   36
 
the expiration of a 15-calendar day waiting period following the filing by the
Parent. Accordingly, it is anticipated that the waiting period under the HSR Act
applicable to the Offer will expire at 11:59 p.m., Eastern time, on November 6,
1998, unless such waiting period is earlier terminated by the FTC or the
Antitrust Division or extended by a request from the FTC or the Antitrust
Division for additional information or documentary material prior to the
expiration of the waiting period.
 
     Pursuant to the HSR Act, the Parent has requested early termination of the
waiting period applicable to the Offer. There can be no assurance, however, that
the 15-day HSR Act waiting period will be terminated early. If either the FTC or
the Antitrust Division were to request additional information or documentary
material from the Parent, the waiting period would expire at 11:59 p.m., Eastern
time, on the tenth calendar day after the date of substantial compliance by the
Parent with such request. Thereafter, the waiting period could be extended again
only by court order or with the consent of the Parent.
 
     If the acquisition of Shares is delayed pursuant to a request by the FTC or
the Antitrust Division for additional information or documentary material
pursuant to the HSR Act, the Offer may, at the discretion of the Parent, subject
to the terms and conditions of the Merger Agreement, be extended and, in any
event, the purchase of and payment for Shares will be deferred until the
applicable waiting period expires or is terminated. Unless the Offer is
extended, any extension of the waiting period will not give rise to any
additional withdrawal rights. See Section 4. Although the Company is required to
file certain information and documentary material with the Antitrust Division
and the FTC in connection with the Offer, neither the Company's failure to make
such filings nor a request from the Antitrust Division or the FTC for additional
information or documentary material made to the Company will extend the waiting
period applicable to the Offer.
 
     The FTC and the Antitrust Division as well as state antitrust enforcement
agencies frequently scrutinize the legality under the antitrust laws of
transactions such as the proposed acquisition of Shares pursuant to the Offer
and the Merger. At any time before or after the Purchaser's acquisition of
Shares pursuant to the Offer, any such agency could take such action under the
antitrust laws as it deems necessary or desirable in the public interest,
including seeking to enjoin the acquisition of Shares pursuant to the Offer or
the Merger or seeking divestiture of Shares acquired by the Purchaser or
divestiture of substantial assets of the Parent, the Company or their respective
subsidiaries. Private parties may also bring legal action under federal and
state antitrust laws under certain circumstances. If any such action by the FTC,
the Antitrust Division or certain other persons should be instituted or pending,
the Parent may extend, terminate or amend the Offer. See Section 13. There can
be no assurance that a challenge to the Offer on antitrust grounds will not be
made or if such challenge is made that the result will be favorable.
 
     Based upon an examination of information available to it relating to the
businesses in which the Parent and its subsidiaries and the Company and its
subsidiaries are engaged, the Parent and the Purchaser believe that consummation
of the Offer and the Merger will not violate the antitrust laws.
 
     The Purchaser will not accept for payment any Shares tendered pursuant to
the Offer unless and until the waiting period requirements imposed by the HSR
Act with respect to the Offer have been satisfied.
 
     State Takeover Statutes.  Section 203 of the Delaware Law prohibits
business combination transactions involving a Delaware corporation (such as the
Company) and an "interested stockholder" (defined generally as any person that
directly or indirectly beneficially owns 15% or more of the outstanding voting
stock of the subject corporation) for three years following the date such person
became an interested stockholder, unless special requirements are met or certain
exceptions apply, including that prior to such date the board of directors of
the subject corporation approved either the business combination or the
transaction which resulted in such person being an interested stockholder. In
the Merger Agreement, the Company has represented that the provisions of Section
203 are not applicable to the Offer or the Merger or the transactions
contemplated by the Stockholders' Agreement.
 
     A number of other states have adopted laws and regulations applicable to
attempts to acquire securities of corporations which are incorporated, or have
substantial assets, stockholders, principal executive offices or principal
places of business, or whose business operations otherwise have substantial
economic effects, in such
 
                                       34
<PAGE>   37
 
states. In 1982, in Edgar v. MITE Corp., the Supreme Court of the United States
invalidated on constitutional grounds the Illinois Business Takeover Statute,
which, as a matter of state securities law, made takeovers of corporations
meeting certain requirements more difficult. However, in 1987 in CTS Corp. v.
Dynamics Corp. of America, the Supreme Court held that the State of Indiana may,
as a matter of corporate law, and, in particular, with respect to 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. The state law before the
Supreme Court was by its terms applicable only to corporations that had a
substantial number of stockholders in the state and were incorporated there.
 
     The Company, directly or through subsidiaries, conducts business in a
number of states throughout the United States, some of which have enacted
takeover laws. The Purchaser does not know whether any of these laws will, by
their terms, apply to the Offer and has not necessarily complied with any such
laws. Should any person seek to apply any state takeover law, the Purchaser will
take such action as then appears desirable, which may include challenging the
validity or applicability of any such statute in appropriate court proceedings.
In the event it is asserted that one or more state takeover laws is applicable
to the Offer and the Merger, and an appropriate court does not determine that it
is inapplicable or invalid as applied to the Offer, the Purchaser might be
required to file certain information with, or receive approvals from, the
relevant state authorities. In addition, if enjoined, the Purchaser might be
unable to accept for payment any 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 payment any Shares tendered. See Section 13.
 
15.  DIVIDENDS AND DISTRIBUTIONS
 
     If, on or after October 21, 1998, the Company should declare or pay any
dividend or other distribution (including, without limitation, the issuance of
additional Shares pursuant to stock dividend or stock split or the issuance of
rights for the purchase of any securities) with respect to the Shares that is
payable or distributable to stockholders of record on a date occurring prior to
the transfer to 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,
then, without prejudice to the Purchaser's rights described in Section 13, (i)
the purchase price per Share payable by the Purchaser pursuant to the Offer will
be reduced in the amount of any such cash dividend or distribution, and (ii) the
whole of any non-cash dividend or distribution (including, without limitation,
additional Shares or rights as aforesaid) will be required to be remitted
promptly and transferred by each tendering stockholder to the Depositary for the
account of the Purchaser accompanied by appropriate documentation of transfer
and pending such remittance or appropriate assurance thereof, the Purchaser will
be entitled to all rights and privileges as owner of any such non-cash dividend,
distribution or right, and may withhold the entire purchase price or deduct from
the purchase price the amount of value of such non-cash dividend, distribution
or right, as determined by the Purchaser in its sole discretion.
 
     If, on or after October 21, 1998, the Company should split the Shares or
combine or otherwise change the Shares or its capitalization, then, without
prejudice to the Purchaser's rights described in Section 13, appropriate
adjustments to reflect such split, combination or change may be made by the
Purchaser in the purchase price and other terms of the Offer, including, without
limitation, the number or type of securities offered to be purchased.
 
16.  FEES AND EXPENSES
 
     The Purchaser has retained Kissel-Blake to act as the Information Agent and
BankBoston, N.A. to act as the Depositary in connection with the Offer. The
Information Agent may contact holders of Shares by mail, telephone, telex,
telecopy, telegraph and personal interview and may request brokers, dealers,
commercial banks, trust companies and other nominees to forward the Offer
material to beneficial owners. Each of the Information Agent and the Depositary
will receive reasonable and customary compensation for its services and will be
reimbursed for certain reasonable out-of-pocket expenses and will be indemnified
against certain liabilities and expenses in connection with the Offer, including
certain liabilities under U.S. federal securities laws.
 
                                       35
<PAGE>   38
 
     The Purchaser will not pay any fees or commissions to any broker or dealer
or any other person for soliciting tenders of Shares pursuant to the Offer
(other than to the Information Agent). Brokers, dealers, commercial banks, trust
companies and other nominees will, upon request, be reimbursed by the Purchaser
for customary mailing and handling expenses incurred by them in forwarding
materials to their customers.

Ladies and Gentlemen:
 
     The undersigned hereby tenders to Lighthouse Weston Corp., a Delaware
corporation (the "Purchaser") and a wholly owned subsidiary of EG&G, Inc., a
Massachusetts corporation, the above-described shares of common stock, par value
$0.01 per share (the "Shares"), of Lumen Technologies, Inc., a Delaware
corporation (the "Company"), pursuant to the Purchaser's offer to purchase all
the outstanding Shares at a price of $7.75 per 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 this Letter of Transmittal (which, together with
any amendments or supplements thereto or hereto, collectively constitute the
"Offer"), receipt of each of which is hereby acknowledged. The undersigned
understands that the Purchaser reserves the right to transfer or assign, in
whole or from time to time in part, to one or more of its affiliates, the right
to purchase all or any portion of the Shares tendered pursuant to the Offer.
 
     Subject to, and effective upon, acceptance for payment of the Shares
tendered herewith in accordance with 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 undersigned hereby sells,
assigns and transfers to, or upon the order of, the Purchaser all right, title
and interest in and to all of the Shares that are being tendered hereby and any
and all dividends and distributions (including, without limitation,
distributions of additional Shares or rights declared, paid or issued with
respect to the tendered Shares on or after October 21, 1998, collectively,
"Distributions"), and irrevocably constitutes and appoints the Depositary the
true and lawful agent and attorney-in-fact of the undersigned with respect to
such Shares and any Distributions with full power of substitution (such power of
attorney being deemed to be an irrevocable power coupled with an interest) to
(a) deliver such Share Certificates and any Distributions, or transfer ownership
of such Shares and any Distributions on the account books maintained by the
Book-Entry Transfer Facility, together in either case with appropriate 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 any Distributions for transfer on the books of the
Company and (c) receive all benefits and otherwise exercise all rights of record
and beneficial ownership of such Shares and any Distributions, all in accordance
with the terms and subject to the conditions of the Offer.
 
     The undersigned hereby irrevocably appoints Angelo D. Castellana, Daniel T.
Heaney and Philip Ayers in their respective capacities as officers of the
Purchaser, and any individuals who shall hereafter succeed to any such office of
the Purchaser, and each of them and any other designees of the Purchaser, as
attorneys-in-fact and proxies of the undersigned, each with full power of
substitution, to the full extent of the undersigned's rights with respect to the
Shares tendered by the undersigned and accepted for payment and paid for by the
Purchaser and any Distributions. This power of attorney and proxy shall be
considered irrevocable and coupled with an interest in the tendered Shares. Such
appointment will be effective when, and only to the extent that, the Purchaser
accepts such Shares for payment and deposits the purchase price therefor with
the Depositary. Upon such deposit, all prior powers of attorney and proxies
given by the undersigned at any time with respect to such Shares and any
Distributions will, without further action, be revoked, and no subsequent powers
of attorney or proxies may be given nor any subsequent written consents executed
by the undersigned (and, if given or executed, will not be deemed effective).
Upon such deposit by the Purchaser, the designees of the Purchaser will, with
respect to such Shares and any Distributions, be empowered to exercise all
voting and other rights of the undersigned 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, by written consent in lieu of any such
meeting or otherwise. The Purchaser reserves the right to require that, in order
for Shares to be deemed validly tendered, immediately upon the Purchaser's
payment for such Shares, the Purchaser must be able to exercise full voting
rights and other rights of a record and beneficial owner with respect to such
Shares and any Distributions, including, without limitation, voting at any
meeting of stockholders or by written consent in lieu of any such meeting.
 
     The undersigned hereby represents and warrants that (a) the undersigned has
full power and authority to tender, sell, assign and transfer the Shares
tendered hereby and any Distributions and (b) when the Shares and any
Distributions are accepted for payment by the Purchaser, the Purchaser will
acquire good, marketable and unencumbered title to the Shares and any
Distributions, 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, shall 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 any
Distributions. In addition, the undersigned shall promptly remit and transfer to
the Depositary for the account of the Purchaser any Distribution 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, subject
<PAGE>   5
 
to applicable law, entitled to all rights and privileges as record and
beneficial owner of any such Distribution and may withhold the entire purchase
price of Shares tendered hereby or deduct from the purchase price the amount or
value of any such Distribution, as determined by the Purchaser in its sole
discretion.
 
     No authority herein conferred or agreed to be conferred shall be affected
by, and all authority herein conferred or agreed to be conferred shall survive,
the death or incapacity of the undersigned and any obligation of the undersigned
hereunder shall be binding upon the heirs, personal representatives, successors
and assigns of the undersigned.
 
     Except as otherwise provided in the Offer to Purchase, tenders of Shares
made pursuant to the Offer are irrevocable. Shares tendered pursuant to the
Offer may be withdrawn at any time prior to the Expiration Date (as defined in
the Offer to Purchase) and, unless theretofore accepted for payment by the
Purchaser pursuant to the Offer, may also be withdrawn at any time after
December 25, 1998. See Section 4 of the Offer to Purchase.
 
     The undersigned understands that tenders of Shares pursuant to any of the
procedures described in Section 3 of the Offer to Purchase and in the
Instructions hereto will constitute the undersigned's acceptance of the terms
and conditions of the Offer. The Purchaser's acceptance of such Shares for
payment will constitute a binding agreement between the undersigned and the
Purchaser upon the terms and subject to the conditions set forth in the Offer.
 
     The undersigned understands that the Offer is conditioned upon, among other
things set forth in the Merger Agreement (as defined in the Offer to Purchase),
there being validly tendered and not withdrawn prior to the expiration of the
Offer that number of Shares which constitutes at least a majority of the Shares
outstanding on a fully-diluted basis (as defined in the Offer to Purchase).
 
     The undersigned understands that, under certain circumstances set forth in
the Offer to Purchase, the Purchaser may terminate or amend the Offer or may not
be required to accept for payment any of the Shares tendered herewith.
 
     Unless otherwise indicated herein under "Special Payment Instructions",
please issue the check for the purchase price of all Shares accepted for payment
and issue or return any Share Certificate(s) for Shares not tendered or not
purchased in the name(s) of the registered holder(s) appearing under
"Description of Shares Tendered". Similarly, unless otherwise indicated herein
under "Special Delivery Instructions", please mail the check for the purchase
price of all Shares accepted for payment and return any Share Certificate(s) for
Shares not tendered or not purchased (and accompanying documents, as
appropriate) to the address of the registered holder(s) appearing under
"Description of Shares Tendered". In the event that both the "Special Delivery
Instructions" and the "Special Payment Instructions" boxes are completed, please
issue the check for the purchase price of all Shares accepted for payment and
return any Share Certificate(s) for Shares not tendered or not purchased in the
name(s) of, and deliver such check and return such Share Certificate(s) to, the
person(s) so indicated. Please credit any Shares tendered herewith by book-entry
transfer that are not purchased by crediting the account at the Book-Entry
Transfer Facility designated above. The undersigned recognizes that the
Purchaser has no obligation pursuant to the "Special Payment Instructions" to
transfer any Shares from the name(s) of the registered holder(s) thereof if the
Purchaser does not accept for payment any of the Shares tendered hereby.

                                  INSTRUCTIONS
 
             FORMING PART OF THE TERMS AND CONDITIONS OF THE OFFER
 
     1.  GUARANTEE OF SIGNATURES.  No signature guarantee is required on this
Letter of Transmittal (a) if this Letter of Transmittal is signed by the
registered holder(s) of Shares (which term, for purposes of this document, shall
include any participant in the Book-Entry Transfer Facility whose name appears
on a security position listing as the owner of Share(s)) tendered herewith,
unless such holder(s) has (have) completed either the box entitled "Special
Payment Instructions" or the box entitled "Special Delivery Instructions", or
(b) if such Share(s) are tendered for the account of a firm which is a
commercial bank, broker, dealer, credit union, savings association or other
entity which is a member in good standing of the Securities Transfer Agents
Medallion Program, the Stock Exchanges' Medallion Program or the New York Stock
Exchange, Inc. Medallion Signature Program (each of the foregoing being referred
to as 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 completed by stockholders either if Share Certificates are
to be forwarded herewith or, unless an Agent's Message is utilized, if delivery
of Shares is to be made by book-entry transfer pursuant to the procedures set
forth in Section 3 of the Offer to Purchase. In order for Shares to be validly
tendered pursuant to the Offer, this Letter of Transmittal (or a facsimile
hereof), properly completed and duly executed, together 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 this Letter of
Transmittal, must be received by the Depositary at one of its addresses set
forth on the front cover hereof prior to the Expiration Date and either (i)
Share Certificates evidencing tendered Shares must be received by the Depositary
at such address or such Shares must be tendered by book-entry transfer and a
timely confirmation of such book-entry transfer (a "Book-Entry Confirmation")
must be received by the Depositary, in each case prior to the Expiration Date or
(ii) the guaranteed delivery procedures described in the following sentence must
be complied with. Stockholders whose Share Certificates are not immediately
available or who cannot deliver their Share Certificates and all other required
documents to reach the Depositary prior to the Expiration Date or who cannot
complete the procedure 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 prior to the
Expiration Date; and (iii) the Share Certificates (or a Book-Entry Confirmation)
evidencing all tendered Shares, in proper form for transfer, together with this
Letter of Transmittal (or a facsimile hereof), properly completed and duly
executed, 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 three New
York Stock Exchange, Inc. ("NYSE") trading days after the date of execution of
such Notice of Guaranteed Delivery.
 
     THE METHOD OF DELIVERY OF THIS LETTER OF TRANSMITTAL, SHARE CERTIFICATES
AND ALL OTHER REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH THE BOOK-ENTRY
TRANSFER FACILITY, IS AT THE SOLE OPTION AND 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. All
tendering stockholders, by execution of this Letter of Transmittal (or a
facsimile hereof), waive any right to receive any notice of the acceptance of
their Shares for payment.
 
     If Share Certificates are forwarded to the Depositary in multiple
deliveries, a properly completed and duly executed Letter of Transmittal must
accompany each such delivery.
 
     3.  INADEQUATE SPACE.  If the space provided herein is inadequate, the
Share Certificate numbers, the number of Shares and any other required
information should be listed on a separate signed schedule attached hereto and
referenced in the box entitled "Description of Shares Tendered".
<PAGE>   9
 
     4.  PARTIAL TENDERS.  (Not Applicable to Book-Entry Stockholders.) If fewer
than all the Shares evidenced by any Share Certificate submitted to the
Depositary herewith 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 cases,
new Share Certificate(s) evidencing the Shares that were evidenced by the Share
Certificate(s) delivered to the Depositary herewith, but which were not tendered
hereby, will be sent to the registered holder(s) shown above, unless otherwise
provided in the box entitled "Special Delivery Instructions", as soon as
practicable after the expiration or termination of the Offer. All Shares
represented by Share 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 with the name(s) as written on
the face of the Share Certificate(s) without alteration, enlargement or any
change whatsoever.
 
     If any of the Shares tendered hereby are owned of record by two or more
persons, all such persons must sign this Letter of Transmittal.
 
     If any of the tendered Shares are registered in the names of different
holders, it will be necessary to complete, sign and submit as many separate
Letters of Transmittal as there are different registrations of Share
Certificates.
 
     If this Letter of Transmittal or any Share Certificates or stock powers is
signed by a trustee, executor, administrator, guardian, attorney-in-fact,
officer of a corporation or other person acting in a fiduciary or representative
capacity, such person should so indicate when signing, and proper evidence
satisfactory to the Purchaser of such person's authority so to act must be
submitted.
 
     If this Letter of Transmittal is signed by the registered holder(s) of the
Shares listed and tendered hereby, no endorsements of Share Certificates or
separate stock powers are required, unless payment is to be made to, or Share
Certificates evidencing Shares not tendered or not purchased are to be issued in
the name of, a person other than the registered holder(s), in which case, the
Share Certificate(s) evidencing the Shares tendered hereby must be endorsed or
accompanied by appropriate stock powers signed exactly as the name(s) of the
registered holder(s) appear(s) on such Share Certificate(s). Signatures on such
Share Certificate(s) or stock powers must be guaranteed by an Eligible
Institution.
 
     If this Letter of Transmittal is signed by a person other than the
registered holder(s) of the Share Certificate(s) listed and tendered hereby, the
Share Certificate(s) must be endorsed or accompanied by appropriate stock
powers, in either case signed exactly as the name(s) of the registered holder(s)
appear on such Share Certificate(s). Signature(s) on such Share Certificate(s)
and stock powers must be guaranteed by an Eligible Institution.
 
     6.  TRANSFER TAXES.  Except as set forth in this Instruction 6, the
Purchaser will pay or cause to be paid any transfer taxes with respect to the
transfer and sale of Shares to it or its order pursuant to the Offer. If,
however, payment of the purchase price of Shares accepted for payment is to be
made to, or if Share Certificate(s) evidencing Shares not tendered or not
purchased are to be issued in the name of, any person other than the registered
holder(s), or if tendered Share Certificates are registered in the name of any
person other than the person(s) signing this Letter of Transmittal, then the
amount of any transfer taxes (whether imposed on the registered holder(s) or
such person or otherwise) payable on account of the transfer to such other
person will be deducted from the purchase price unless satisfactory evidence of
the payment of such taxes, or an exemption therefrom, is submitted.
 
     EXCEPT AS SET FORTH IN THIS INSTRUCTION 6, IT WILL NOT BE NECESSARY FOR
TRANSFER TAX STAMPS TO BE AFFIXED TO THE SHARE CERTIFICATE(S) TENDERED HEREBY.
 
     7.  SPECIAL PAYMENT AND DELIVERY INSTRUCTIONS.  If a check for the purchase
price of Shares accepted for payment is to be issued in the name of, or Share
Certificate(s) evidencing Shares not tendered or not purchased are to be issued
or returned to, a person other than the signer of this Letter of Transmittal or
if a check or such Share Certificate(s) are to be returned to a person other
than the signer of this Letter of Transmittal or to an address of the signer
other than that shown in this Letter of Transmittal, the appropriate boxes on
this Letter of Transmittal must be completed.
 
     8.  WAIVER OF CONDITIONS.  Subject to the terms of the Merger Agreement,
the conditions of the Offer may be waived by the Purchaser, in whole or in part,
at any time and from time to time in its sole discretion.
<PAGE>   10
 
     9.  SUBSTITUTE FORM W-9.  Under U.S. federal income tax law, a stockholder
whose tendered Shares are purchased is required to provide the Depositary with
such stockholder's correct taxpayer identification number ("TIN") (e.g., social
security number or employer identification number) on Substitute Form W-9 below
and to certify whether such stockholder is subject to backup withholding of
federal income tax. If a tendering stockholder has been notified by the Internal
Revenue Service (the "IRS") that such stockholder is subject to backup
withholding, such stockholder must cross out item 2 of the Certification box
(Part 2) of the Substitute Form W-9, unless such stockholder has since been
notified by the IRS that such stockholder is no longer subject to backup
withholding. Failure to provide the information on the Substitute Form W-9 may
subject the tendering stockholder to 31% federal income tax withholding on the
payment of the purchase price of all Shares purchased from the stockholder. If
the Depositary is not provided with the correct TIN, the IRS may subject the
stockholder or other payee to a $50 penalty.
 
     Certain stockholders are not subject to these backup withholding and
reporting requirements. Exempt recipients, such as corporations, are also
requested to provide their TIN and check the "Exempt" box in Part 3. Foreign
individuals or entities must submit a Form W-8, signed under penalties of
perjury, attesting to their foreign 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 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 IRS.
 
     The "Awaiting TIN" 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 "Awaiting TIN" 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. If the "Awaiting TIN" 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 unless a properly certified
TIN is provided to the Depositary within 60 days.
 
     The stockholder is required to give the Depositary the TIN 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.  QUESTIONS AND REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.  Questions
and requests for assistance may be directed to the Information Agent at its
address and telephone numbers set forth below. Additional copies of the Offer to
Purchase, this Letter of Transmittal and all other tender offer materials may be
obtained from the Information Agent or from brokers, dealers, commercial banks,
trust companies or other nominee at the Purchaser's expense.
 
     11.  LOST, DESTROYED OR STOLEN CERTIFICATES.  If any Share Certificate has
been lost, destroyed or stolen, the stockholder should promptly notify
Kissel-Blake, which is acting as the Information Agent. The stockholder will
then be instructed as to the steps that must be taken in order to replace such
Share Certificate. This Letter of Transmittal and related documents cannot be
processed until the procedures for replacing lost, destroyed or stolen Share
Certificates have been followed.
 
     IMPORTANT: THIS LETTER OF TRANSMITTAL (OR A FACSIMILE HEREOF), PROPERLY
COMPLETED AND DULY EXECUTED, OR, IF APPROPRIATE, AN AGENT'S MESSAGE, TOGETHER
WITH SHARE CERTIFICATES OR CONFIRMATION OF BOOK-ENTRY TRANSFER AND ALL OTHER
REQUIRED DOCUMENTS, OR A PROPERLY COMPLETED AND DULY EXECUTED NOTICE OF
GUARANTEED DELIVERY, MUST BE RECEIVED BY THE DEPOSITARY PRIOR TO THE EXPIRATION
DATE.

PRIVACY ACT NOTICE.  Section 6109 requires most recipients of dividend,

who must report the payments to the IRS. The IRS uses the numbers for
identification purposes and to help verify the accuracy of tax returns. Payers
must be given the numbers whether or not recipients are required to file a tax
return. Payers must generally withhold 31% of taxable interest, dividend, and
certain other payments to a payee who does not furnish a taxpayer identification
number to a payer. Certain penalties may also apply.
 
PENALTIES
 
(1) PENALTY FOR FAILURE TO FURNISH TAXPAYER IDENTIFICATION NUMBER. -- If you
fail to furnish your taxpayer identification number to a payer, you are subject
to a penalty of $50 for each such failure unless your failure is due to
reasonable cause and not to willful neglect.
 
(2) FAILURE TO REPORT CERTAIN DIVIDEND AND INTEREST PAYMENTS. -- If you fail to
include any portion of an includable payment for interest, dividends, or
patronage dividends in gross income, such failure will be treated as being due
to negligence and will be subject to a penalty of 5% on any portion of an
under-payment attributable to that failure unless there is clear and convincing
evidence to the contrary.
 
(3) CIVIL PENALTY FOR FALSE INFORMATION WITH RESPECT TO WITHHOLDING. -- If you
make a false statement with no reasonable basis which results in no imposition
of backup withholding, you are subject to a penalty of $500.
 
(4) CRIMINAL PENALTY FOR FALSIFYING INFORMATION. -- Falsifying certifications or
affirmations may subject you to criminal penalties including fines and/or
imprisonment. FOR ADDITIONAL INFORMATION CONTACT YOUR TAX CONSULTANT OR THE
INTERNAL REVENUE SERVICE.

                            LUMEN TECHNOLOGIES, INC.

                             LIGHTHOUSE WESTON CORP.

                                   EG&G, INC.

         Lighthouse Weston Corp., a Delaware corporation (the "Purchaser") and a
wholly owned subsidiary of EG&G, Inc., a Massachusetts corporation (the
"Parent"), is offering to purchase all the outstanding shares of common stock,
par value $0.01 per share (the "Shares"), of Lumen Technologies, Inc., a
Delaware corporation (the "Company"), at a purchase price of $7.75 per 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 dated October 27, 1998 (the
"Offer to Purchase") and in the related Letter of Transmittal (which, together
with any amendments or supplements thereto, collectively constitute the
"Offer").



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

                         THE OFFER AND WITHDRAWAL RIGHTS
               WILL EXPIRE AT 12:00 MIDNIGHT, NEW YORK CITY TIME,
          ON TUESDAY, NOVEMBER 24, 1998, UNLESS THE OFFER IS EXTENDED.

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

         The Offer is being made pursuant to an Agreement and Plan of Merger,
dated as of October 21, 1998 (the "Merger Agreement"), by and among the Parent,
the Purchaser and the Company, pursuant to which, following the consummation of
the Offer and the satisfaction of the other conditions set forth in the Merger
Agreement (but not prior to January 11, 1999, unless requested otherwise by the
Parent) and in accordance with the relevant provisions of the Delaware General
Corporation Law (the "Delaware Law"), the Purchaser will be merged with and into
the Company (the "Merger"). Upon the effective time of the Merger, each
outstanding Share (other than Shares held by the Parent, the Purchaser or the
Company or any direct or indirect subsidiary of the Parent, the Purchaser or the
<PAGE>   2
Company, and Shares held by stockholders, if any, who are entitled to and
perfect their appraisal rights under Delaware Law) will be cancelled and
converted into the right to receive $7.75 per Share in cash, without interest.
The Merger Agreement is more fully described in the Offer to Purchase. The
purpose of the Offer is to enable the Parent, through its wholly owned
subsidiary, to acquire control of, and the entire equity interest in, the
Company.

           The Parent and the Purchaser have entered into a Stockholders'
Agreement with certain officers and directors of the Company (the "Management
Stockholders"), with respect to 993,684 Shares outstanding as of the date of the
Merger Agreement and beneficially owned by the Management Stockholders and an
additional 1,752,338 Shares subject to options held by the Management
Stockholders. The Shares subject to the Stockholders' Agreement represent
between 4.5% (assuming the Management Stockholders do not exercise any of their
options) and 11.5% (assuming the Management Stockholders do not exercise any of
their options) of the Shares on a fully diluted basis (as defined in the Offer
to Purchase). Pursuant to the Stockholders' Agreement, the Stockholders have
agreed to tender all their outstanding Shares pursuant to the Offer, to vote all
their outstanding Shares in favor of the Merger and not to transfer such Shares
without the Parent's consent and have granted the Purchaser a proxy to vote such
Shares in favor of the Merger.

         THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS, THERE BEING VALIDLY
TENDERED AND NOT WITHDRAWN PRIOR TO THE EXPIRATION OF THE OFFER THAT NUMBER OF
SHARES WHICH CONSTITUTES AT LEAST A MAJORITY OF THE OUTSTANDING SHARES ON A
FULLY-DILUTED BASIS (AS DEFINED IN THE OFFER TO PURCHASE). THE OFFER IS ALSO
SUBJECT TO CERTAIN OTHER TERMS AND CONDITIONS CONTAINED IN THE OFFER TO
PURCHASE.

         THE BOARD OF DIRECTORS OF THE COMPANY HAS UNANIMOUSLY DETERMINED THAT
THE OFFER AND THE MERGER ARE FAIR TO, AND IN THE BEST INTERESTS OF, THE
STOCKHOLDERS OF THE COMPANY, HAS APPROVED AND FOUND ADVISABLE THE MERGER
AGREEMENT, THE OFFER AND THE MERGER AND RECOMMENDS THAT THE STOCKHOLDERS OF THE
COMPANY ACCEPT THE OFFER AND TENDER THEIR SHARES PURSUANT TO THE OFFER.

         For purposes of the Offer, the Purchaser will be deemed to have
accepted for payment, and thereby purchased, Shares validly tendered and not
properly withdrawn if, as and when the Purchaser gives oral or written notice to
BankBoston, N.A. (the "Depositary") of the Purchaser's acceptance for payment of
such Shares pursuant to the Offer. Upon the terms and subject to the conditions
of the Offer, payment for Shares so accepted for payment pursuant to the Offer
will be made by deposit of the aggregate 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 such payment to
stockholders whose Shares have been accepted for payment. In all cases, payment
for Shares tendered and accepted for payment pursuant to the Offer will be made
only after timely receipt by the Depositary of (i) certificates evidencing
Shares ("Share Certificates") or timely confirmation of a book-entry transfer of
such Shares into the Depositary's account at The Depository Trust Company
pursuant to the procedures set forth in Section 3 of the Offer to Purchase, (ii)
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 Section 2 of the Offer to Purchase) in connection with a book-entry
transfer and (iii) any other documents required by the Letter of Transmittal.
UNDER NO CIRCUMSTANCES WILL INTEREST ON THE PURCHASE PRICE FOR SHARES BE PAID,
REGARDLESS OF ANY EXTENSION OF THE OFFER OR ANY DELAY IN MAKING SUCH PAYMENT.

         The term "Expiration Date" means 12:00 midnight, New York City time, on
Tuesday, November 24, 1998, unless and until the Purchaser, in its sole
discretion (but subject to the terms and conditions of the Merger Agreement),
shall have extended the period during which the Offer is open, in which event
the term "Expiration Date" shall mean the latest time and date at which the
Offer, as so extended by the Purchaser, shall expire.

         Subject to the applicable rules and regulations of the Securities and
Exchange Commission, the Purchaser expressly reserves the right, in its sole
discretion (but subject to the terms and conditions of the Merger Agreement), at
any time and from time to time, and regardless of whether or not any of the
events set forth in Section 13 of the Offer to Purchase shall have occurred, (i)
to extend the period during which the Offer is open and thereby delay acceptance
for payment of, or payment for, any Shares, by giving oral or written notice of
such extension to the Depositary and (ii) to amend the Offer in any other
respect by giving oral or written notice of such amendment to the Depositary.
There can be no assurance that the Purchaser will exercise its right to extend
the Offer. Any such extension will be followed by a public announcement thereof
no later than 9:00 a.m., New York City time, on the next business day after the
previously scheduled Expiration Date. During any such extension, all Shares
previously tendered and not properly withdrawn will remain subject to the Offer,
subject to the rights of a tendering stockholder to withdraw such stockholder's
Shares.
<PAGE>   3
         Except as otherwise provided in Section 4 of the Offer to Purchase,
tenders of Shares made pursuant to the Offer are irrevocable. Shares tendered
pursuant to the Offer may be withdrawn at any time prior to the Expiration Date
and, unless theretofore accepted for payment pursuant to the Offer, may also be
withdrawn at any time after December 25, 1998. 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 the name of the registered holder of the Shares to be
withdrawn, if different from that of the person who tendered such Shares. If
Share Certificates to be withdrawn have been delivered or otherwise identified
to the Depositary, then, prior to the physical release of such Share
Certificates, the tendering stockholder must also submit the serial numbers
shown on such Share Certificates to the Depositary and the signatures on the
notice of withdrawal must be guaranteed by an Eligible Institution (as defined
in Section 3 of the Offer to Purchase), unless such Shares have been tendered
for the account of an Eligible Institution. If Shares have been tendered
pursuant to the procedures for book-entry transfer, as set forth in Section 3 of
the Offer to Purchase, any notice of withdrawal must specify the name and number
of the account at the Book-Entry Transfer Facility to be credited with the
withdrawn Shares and must otherwise comply with the procedures of the Book-Entry
Transfer Facility. Withdrawals may not be revoked and any Shares properly
withdrawn will thereafter be deemed not to have been validly tendered for
purposes of the Offer. However, withdrawn Shares may be retendered at any time
prior to the Expiration Date by following one of the procedures described in
Section 3 of the Offer to Purchase. All questions as to the form and validity
(including the time of receipt) of any notice of withdrawal will be determined
by the Purchaser, in its sole discretion, whose determination will be final and
binding.

         The Company has provided the Purchaser with the Company's stockholders
list and security position listings for the purpose of disseminating the Offer
to holders of Shares. The Offer to Purchase, the related Letter of Transmittal
and, if required, other relevant material 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 Company's stockholders list or, if applicable, who are listed as
participants in a clearing agency's security position listing for subsequent
transmittal to beneficial owners of Shares.

         The information required to be disclosed by 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 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.

         Questions and requests for assistance or for additional copies of the
Offer to Purchase, the Letter of Transmittal and all other tender offer
materials may be directed to the Information Agent as set forth below, and
copies will be furnished promptly at the Purchaser's expense. No fees or

               EG&G AND LUMEN TECHNOLOGIES ANNOUNCE ACQUISITION
               ------------------------------------------------
        $250M DEAL BROADENS EG&G'S SPECIALTY LIGHTING PRODUCT OFFERING
        --------------------------------------------------------------


WELLESLEY, MASS ... EG&G, Inc (NYSE: EGG) and Lumen Technologies, Inc.
(NYSE: LNM), Rye, New York, jointly announced today that they have entered into
a definitive agreement for EG&G to acquire Lumen, a maker of high-technology
specialty light sources for approximately $250 million in cash and assmed debt.

The acquisition has been approved by the Boards of both companies. Under the
agreement, a wholly owned subsidiary of EG&G will commence a tender offer to
purchase all outstanding shares of Lumen common stock for $7.75 per share in
cash. The offer will be conditioned upon the tender of at least a majority of
the Lumen common shares outstanding and certain other conditions. Following
consummation of the offer, EG&G's subsidiary will be merged with Lumen and any
remaining shares of Lumen common stock will be converted into the right to
receive $7.75 per share.

As a result of this acquisition, Lumen will add a product line that includes
high-intensity specialty discharge lamps for medical fiberoptic illumination,
cinema projection and stage and studio lighting to EG&G's Optoelectronics
product offerings. EG&G products include specialty flashlamps, as well as
flashtubes used every year in more than 100 million single use cameras.
Together, the companies will be positioned to serve a diverse customer base in
high-growth, specialty light-source markets.

Lumen had pro forma 1997 sales of $138.4 million and pro forma six month 1998
sales of $77 million. Lumen has an employee base of 1,140 and operations in
California, Connecticut, the United Kingdom and Italy.

EG&G Chairman and CEO John M. Kucharski said: "The acquisition of Lumen
Technologies reinforces and complements EG&G's positioning strategy. It
provides a broading vehicle for EG&G's technology to move up the
optoelectronics value chain."

"Lumen Technologies is a strong strategic fit for EG&G and will complement our
Optoelectronics' product mix," explained Gregory L. Summe, EG&G President and
COO. "Our combined manufacturing, selling, distribution and R&D expertise will
greatly improve our ability to serve our customers.

"This is a win-win situation," Summe continued. "We gain a company renowned for
developing state-of-the-art lamps and related products used for medical and
projection applications and we gain access to leading suppliers of medical
fiberoptic systems. Lumen benefits from our low-cost manufacturing facilities
and the opportunity to work with suppliers for the major components of lamps
and related systems. We expect this acquisition to be slightly accretive to
1999 earnings per share."

Lumen Technologies Chairman Martin E. Franklin said: "EG&G and Lumen 
Technologies are a perfect fit. Through this combination, Lumen will have the 
capacity to generate faster growth than it could as an independent company. 
EG&G is acquiring a company with industry-leading management and technology. 
We wish EG&G every success."

The 51-year history of EG&G started with high-technology application of light.
EG&G founder Harold "Doc" Edgerton commercialized the use of the stroboscopic
light for engineering analyses and built the Company from there. Today, the
EG&G Optoelectronic Strategic Business Unit designs and manufactures optical
sensors ranging from simple photocells to sophisticated imaging systems, light
sources that include flashlamps and laser diodes, and complex devices for
secure pyrotechnic arming and triggering. Micromachined sensors and amorphous
silicon detectors are part of the EG&G product line.

Inc., a corporation organized under the laws of the State of Delaware (the

                                   BACKGROUND

         A.       The respective Boards of Directors of the Parent, the
Purchaser and the Company have duly approved and found advisable this Agreement

the terms and conditions of this Agreement.

         B.       In furtherance of such acquisition, it is proposed that the

cash, without interest thereon, upon the terms and subject to the conditions set
forth in this Agreement.

         C.       The Board of Directors of the Company unanimously has
determined that the Offer is fair to, and in the best interests of, the
Company's stockholders and has duly approved the Offer and unanimously resolved
to recommend its acceptance by the holders of Shares.

         D.       The respective Boards of Directors of the Parent, the
Purchaser and the Company have each duly approved the merger of the Purchaser
and the Company on the terms and subject to the conditions of this Agreement
(the "Merger") following consummation of the Offer and the Boards of Directors
of the Company and the Purchaser have each, by unanimous vote, duly resolved to
recommend approval of the Merger by their respective stockholders.

         E.       In connection with such acquisition, the Parent and the
Purchaser have entered into a Stockholders' Agreement dated of even date
herewith (the "Stockholders' Agreement") with certain stockholders of the
Company.

         F.       The respective Boards of Directors of the Parent, the
Purchaser and the Company have each duly approved all of the other transactions
contemplated by this Agreement, including without limitation, for the purposes
of satisfying the requirements of Section 203 of the Delaware General
Corporation Law, the Stockholders' Agreement.

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants herein contained and for other good and valuable consideration the
receipt and adequacy of which are hereby acknowledged, the Parent, the Purchaser
and the Company hereby agree as follows:


                                    ARTICLE 1
                                    THE OFFER

         1.1      THE OFFER.

                  (a)      Provided that this Agreement shall not have been
terminated in accordance with Section 8.1 hereof and nothing shall have occurred
and be continuing that would result in a failure to satisfy any of the
conditions set forth in ANNEX I hereto, the Purchaser shall (i) no later than
the business day following the date of this Agreement, publicly announce its
intention to make the Offer and (ii) within five business days of such
announcement, commence (within the meaning of Rule 14d-2(a) under the Securities
Exchange Act of 1934, as amended (the "Exchange Act")), the Offer for all
Shares, subject to the conditions set forth in ANNEX I, at a price of $7.75 per
Share, net to the seller in cash, without interest thereon. Subject to the
conditions set forth in ANNEX I, the Purchaser shall accept for payment, and pay
for, all shares validly tendered and not withdrawn pursuant to the Offer that
the Purchaser becomes obligated to accept for payment, and pay for, pursuant to
the Offer as soon as practicable after the expiration of the Offer and in no
event later than five business days after the expiration of the Offer.

                  (b)      The Offer shall be made by means of the Offer
Documents (as defined below), which shall not contain any condition not set
forth in ANNEX I hereto and shall be open for a period of not less than 20
business days. The Purchaser expressly reserves the right, subject to compliance
with the Exchange Act, to modify the terms of the Offer, except that, without
the consent of the Company, the Purchaser shall not amend or waive the Minimum
Condition (as defined in ANNEX I hereto), reduce the maximum number of Shares to
be purchased, reduce the price to be paid per Share pursuant to the Offer,
change the form of consideration to be paid in the Offer, impose conditions to
the Offer in addition to those set forth in ANNEX I, or amend any other material
term of the Offer in a manner adverse to the holders of the Shares.
Notwithstanding the foregoing, the Purchaser may, in its sole discretion, (A)
extend the Offer if at the scheduled or any extended expiration date of the
Offer any of the conditions set forth on ANNEX I (including the Minimum
Condition) shall not be satisfied or waived, until such time as such conditions
are satisfied or waived, and (B) extend the Offer for any period required by any
rule, regulation, interpretation or position of the Securities and Exchange
Commission (the "Commission") or the staff thereof applicable to the Offer;
provided, however, that, without the Company's written consent, the Purchaser
may not extend the expiration date of the Offer pursuant to this sentence to a
date later than 11:59 p.m. on December 31, 1998.

                  (c)      On the date of commencement of the Offer, the Parent
and the Purchaser shall file with the Commission a Tender Offer Statement on
Schedule 14D-1 (together with all amendments and supplements thereto, the
"Schedule 14D-1") with respect to the Offer that will contain an offer to
purchase and the related letter of transmittal (which documents, together with
any supplements or amendments thereto, are referred to herein collectively as
the "Offer Documents") and shall promptly mail the Offer Documents to the
Company's stockholders. The Parent and the Purchaser agree that the Offer
Documents shall comply as to form in all material respects with the requirements
of the Exchange Act and the rules and regulations promulgated thereunder, and
the Offer Documents, on the date first filed with the Commission and on the date
first published, sent or given to the Company's stockholders, shall not contain
any untrue statement of a material fact or omit to state any material fact
required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading, except that no representation or warranty is made by the Parent or
the Purchaser with respect to written information supplied by the Company or any
of its stockholders specifically for inclusion or incorporation by reference in
the Offer Documents. The Parent, the Purchaser and the Company each agrees
promptly to correct any written information provided by it for use in the
Schedule 14D-1 or the Offer Documents if and to the extent that such information
shall have become false or misleading in any material respect, and the Parent
and the Purchaser further agree to take all steps necessary to amend or
supplement the Schedule 14D-1 and, as applicable, the Offer Documents and to
cause the Schedule 14D-1 as so amended and supplemented to be filed with the
Commission and the Offer Documents as so amended and supplemented to be
disseminated to holders of Shares, in each case as and to the extent required by
applicable securities laws. The Company and its counsel shall be given
reasonable opportunity to review and comment upon the Offer Documents prior to
their filing with the Commission or dissemination to the stockholders of the
Company. The Parent and the Purchaser shall provide the Company and its counsel
with a copy of any written comments or telephonic notification of any verbal
comments the Parent or the Purchaser may receive from the Commission or its
staff with respect to the Offer promptly after the receipt thereof and shall
provide the Company and its counsel with a copy of any written responses thereto
and telephonic notification of any verbal responses thereto of the Parent or the
Purchaser or their counsel.

                  (d)      The Parent shall provide or cause to be provided to
the Purchaser on a timely basis the funds necessary to purchase any and all
Shares that the Purchaser becomes obligated to purchase pursuant to the Offer.

                  (e)      The Purchaser shall be entitled to deduct and
withhold from the consideration otherwise payable pursuant to the Offer such
amounts as may be required to be deducted and withheld with respect to the
making of such payment under the Internal Revenue Code of 1986, as amended (the
"Code"), or under any applicable law.

         1.2      COMPANY ACTION.

                  (a)      The Company hereby approves of and consents to the
Offer and represents and warrants that the Board of Directors of the Company
(the "Company's Directors"), at a meeting duly called and held, (i) has duly
adopted and approved, by unanimous vote, (A) the Offer, the Merger and this
Agreement, and the transactions contemplated hereby and thereby, and (B) solely
for the purpose of satisfying the requirements of Section 203 of the Delaware
Law, the Stockholders' Agreement and the transactions contemplated thereby; (ii)
has determined that each of the transactions contemplated by this Agreement,
including the Offer and the Merger are fair to and in the best interests of the
stockholders of the Company; and (iii) after consideration of its fiduciary
duties under applicable laws, has resolved to recommend acceptance of the Offer
by holders of Shares and to recommend adoption and approval of the Merger
pursuant to the Delaware General Corporation Law (the "Delaware Law") by holders
of Shares (if stockholder approval of the Merger is required by the Delaware
Law).

                  (b)      The Company agrees to file with the Commission,
contemporaneously with the commencement of the Offer, a
Solicitation/Recommendation Statement on Schedule 14D-9 (together with all
amendments and supplements thereto, the "Schedule 14D-9") and to disseminate the
Schedule 14D-9, to the extent required by Rule 14d-9 promulgated under the
Exchange Act and any other applicable laws, to the stockholders of the Company
no later than the date on which the Purchaser mails the Offer Documents to such
stockholders. Except and to the extent otherwise permitted pursuant to Section
6.5 below, the Offer Documents and the Schedule 14D-9 shall contain the
recommendation of the Company's Directors that the holders of Shares accept the
Offer, and the Company hereby consents to the inclusion in the Offer Documents
of such recommendation. The Company agrees that the Schedule 14D-9 shall comply
as to form in all material respects with the requirements of the Exchange Act
and the rules and regulations promulgated thereunder and the Schedule 14D-9, on
the date first filed with the Commission and on the date first published, sent
or given to the Company's stockholders, shall not contain any untrue statement
of a material fact or omit to state any material fact required to be stated
therein or necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading, except that no
representation or warranty is made by the Company with respect to written
information supplied by the Parent or the Purchaser specifically for inclusion
or incorporation by reference in the Schedule 14D-9. The Company, the Parent and
the Purchaser each agrees promptly to correct any written information provided
by it for use in the Schedule 14D-9 if and to the extent that such information
shall have become false or misleading in any material respect, and the Company
further agrees to take all steps necessary to amend or supplement the Schedule
14D-9 and to cause the Schedule 14D-9 as so amended or supplemented to be filed
with the Commission and disseminated to the Company's stockholders, in each case
as and to the extent required by applicable securities laws. The Parent and its
counsel shall be given reasonable opportunity to review and comment upon the
Schedule 14D-9 prior to its filing with the Commission or dissemination to
stockholders of the Company. The Company shall provide the Parent and its
counsel with a copy of any written comments or telephonic




                                       -4-


<PAGE>   11

notification of any verbal comments the Company may receive from the Commission
or its staff with respect to the Offer promptly after the receipt thereof and
shall provide the Parent and its counsel with a copy of any written responses
thereto and telephonic notification of any verbal responses thereto of the
Company or its counsel.

                  (c)      The Company has received the written opinion of
Raymond James & Associates, Inc. (the "Financial Advisor"), that, on the basis
of and subject to the assumptions set forth therein, the cash consideration of
$7.75 per Share to be received by holders of Shares pursuant to the Offer and
the Merger is fair to the holders of Shares from a financial point of view (the
"Fairness Opinion"). The Company has delivered to the Parent and the Purchaser a
copy of the Fairness Opinion, together with the Financial Advisor's written
consent to the inclusion of or reference to the Fairness Opinion in the Schedule
14D-1, the Offer Documents, the Schedule 14D-9 and the Proxy Statement (as
defined in Section 6.1).

                  (d)      The Company represents that each member of the
Company's Board of Directors and each executive officer of the Company has
advised the Company that his current intention is to tender all Shares, if any,
beneficially owned by him pursuant to the Offer, other than those individuals,
if any, for whom the tender of such Shares would cause them to incur liability
under the provisions of Section 16(b) of the Exchange Act (the "Section 16
Shares"). As to Section 16 Shares, the Company represents that each executive
officer and director holding Section 16 Shares, if any, has advised the Company
that it is his current intention to vote such Shares in favor of the Merger.

                  (e)      In connection with the Offer and the Merger, the
Company will promptly furnish to the Purchaser or its designee mailing labels
containing the names and addresses of the record holders of the Shares as of a
recent date and of those persons becoming record holders subsequent to such date
and, to the extent known, a list of the beneficial owners of the Shares as of a
recent date, together with copies of all security position listings and all
other computer files and other information in the Company's possession or
control regarding the beneficial owners' ownership of the Shares, and shall
furnish to the Purchaser such information and assistance (including updated
lists and information) as it may reasonably request for the purpose of
communicating the Offer to the Company's stockholders. From and after the date
of this Agreement, all such information concerning the Company's record and, to
the extent known, beneficial holders shall be made available to the Purchaser.
Subject to the requirements of applicable laws and except for such steps as are
necessary to disseminate the Offer Documents and any other documents necessary
to consummate the Offer and the Merger, the Parent and the Purchaser shall,
until consummation of the Offer, hold in confidence the information contained in
any of such labels and lists, shall use such information only in connection with
the Offer and the Merger and, if this Agreement shall be terminated in
accordance with Section 8.1, shall deliver to the Company all copies of such
information then in their possession or under their control.

         1.3      DIRECTORS.

                  (a)      Promptly upon the acceptance for payment of and
payment by the Purchaser for any Shares pursuant to the Offer, and from time to
time thereafter as Shares are accepted for payment and paid for by the
Purchaser, the Purchaser shall be entitled to designate such number of the
Company's Directors, rounded to the nearest whole number, as will give the
Purchaser representation on the Company's Board of Directors equal to at least
that number of directors which equals the greater of (i) a majority and (ii) the
product of the total number of the Company's Directors (after giving effect to
the directors elected pursuant to this sentence) multiplied by the percentage
that such number of Shares so accepted for payment and paid for by the Purchaser
bears to the number of Shares outstanding, and the Company shall, upon the
written request of the Purchaser, at such time, promptly take such actions as
are necessary to cause the Purchaser's designees to be so elected or appointed,
including without limitation increasing the size of the Company's Board of
Directors or using its best efforts to secure the resignations of incumbent
directors or both; PROVIDED, HOWEVER, that, notwithstanding the Purchaser's
right to designate certain of the Company's Directors, until the Effective Time
(as defined in Section 2.3), the Company's Directors shall include at least
three directors who are directors on the date hereof (the "Independent
Directors"); provided further, that, if the number of Independent Directors
shall be reduced below three for any reason whatsoever, any remaining
Independent Directors shall be entitled to designate a person to fill such
vacancies and such person shall be deemed to be an Independent Director for
purposes of this Agreement or, if no Independent Directors then remain, the
other directors shall designate three persons to fill such vacancies who shall
not be designees, stockholders, directors, officers, employees or affiliates of
the Parent or the Purchaser, and such persons shall be deemed to be Independent
Directors for purposes of this Agreement. Subject to applicable laws, the
Company shall take all action necessary to effect the election of directors as
provided in this Section 1.3(a), including mailing to its stockholders the
information required by Section 14(f) of the Exchange Act and Rule 14f-1
promulgated thereunder as part of the Schedule 14D-9. The Parent and the
Purchaser shall supply to the Company and be solely responsible for any
information with respect to them and their designees required by Section 14(f)
of the Exchange Act and Rule 14f-1 promulgated thereunder.

                  (b)      Notwithstanding anything in this Agreement to the
contrary, subject to the terms of the Company's Certificate of Incorporation and
By-laws, in the event that the Purchaser's designees are appointed or elected as
Company Directors, after the acceptance for payment of Shares pursuant to the
Offer and prior to the Effective Time, the affirmative vote of a majority (or,
if there is only one or two Independent Directors, the single or unanimous vote,
as the case may be) of the Independent Directors (who shall act as an
independent committee of the Board of Directors for this purpose) shall be
required, and alone shall be sufficient, to (i) amend or terminate this
Agreement by the Company, (ii) exercise or waive any of the Company's rights or
remedies hereunder, (iii) extend the time for performance of the Parent's and
the Purchaser's respective obligations hereunder, or (iv) approve any other
action by the Company that the Independent Directors reasonably determine would
materially

adversely affect the interests of the stockholders of the Company (other than
the Parent, the Purchaser and their affiliates) with respect to the transactions
contemplated hereby. The Board of Directors shall not delegate any matter set
forth in this Section 1.3(b) to any committee of the Board.

                  (c)      The Company hereby represents and warrants that the
Company's Directors, at a meeting duly called and held, has by unanimous vote,
acknowledging that such vote will be relied upon by the Parent and the Purchaser
in connection with the transactions contemplated hereby and, to the extent
permitted by applicable law, shall therefore be irrevocable and not subject to
amendment, repeal or modification, resolved in accordance with Section 5.13 of
the Agreement and Plan of Merger dated as of October 30, 1997, among the
Company, BILC Acquisition Corp, and ILC Technology Inc. (the "ILC Merger
Agreement"), that (i) prior to the Effective Time any of the Company's Directors
elected on behalf of the Purchaser pursuant to paragraph (a) above shall
constitute "Company Nominees" and "BEC Nominees" (as such terms are defined in
the ILC Merger Agreement) and (ii) from and after the Effective Time, all of the
Company's Directors nominated or designated for election by the Parent or the
Purchaser shall constitute "Company Nominees" and "BEC Nominees" pursuant to
Section 5.13 of the ILC Merger Agreement.

                                   THE MERGER

         2.1      THE MERGER. At the Effective Time (as defined in Section 2.3),
in accordance with this Agreement and the Delaware Law, the Purchaser shall be
merged with and into the Company, the separate existence of the Purchaser shall
cease and the Company shall continue as the surviving corporation of the Merger.
The Company is hereinafter sometimes referred to as the "Surviving Corporation."
At the election of the Parent, any direct or indirect wholly owned subsidiary of
the Parent organized under the laws of a state of the United States may be
substituted for the Purchaser as a constituent corporation in the Merger for
purposes of this Section 2.1. In such event, the parties agree to execute an
appropriate amendment to this Agreement in order to reflect the foregoing.

         2.2      EFFECT OF THE MERGER. At the Effective Time, the Surviving
Corporation shall continue its corporate existence under the laws of the State
of Delaware and the Merger shall have the effects set forth in Section 259 of
the Delaware Law.

         2.3      CONSUMMATION OF THE MERGER. As soon as is practicable after
the satisfaction or waiver of the conditions set forth in Article 7 hereof, but
not prior to January 11, 1999 unless requested otherwise by the Parent, the
parties hereto will cause the Merger to be consummated by delivering to the
Secretary of State of the State of Delaware a certificate of merger or a
certificate of ownership and merger (the "Certificate of Merger") in such form
or forms as may be required by, and executed and acknowledged in accordance
with, the relevant provisions of the Delaware Law, and shall make all other
filings and recordings 




                                       -7-

required by the Delaware Law in connection with the Merger. The Merger shall
become effective at the time that the Secretary of State of the State of
Delaware files the Certificate of Merger in accordance with the relevant
provisions of the Delaware Law (or at such later time, which shall be as soon as
reasonably practicable, specified as the effective time in the Certificate of
Merger). The term "Effective Time" shall mean the date and time of the filing of
the Certificate of Merger by the Secretary of State of the State of Delaware (or
such later time, which shall be as soon as reasonably practicable, as may be
specified in the Certificate of Merger).

         2.4      CERTIFICATE OF INCORPORATION; BY-LAWS; DIRECTORS AND OFFICERS.
The Certificate of Incorporation and By-laws of the Purchaser as in effect
immediately prior to the Effective Time shall be the Certificate of
Incorporation and By-laws of the Surviving Corporation until thereafter amended
as provided under the Delaware Law, provided that at the Effective Time (a)
Article I of the Certificate of Incorporation of the Surviving Corporation shall
be amended to read as follows: "The name of the corporation is LUMEN
TECHNOLOGIES, INC.", (b) the indemnification provisions set forth in the
Certificate of Incorporation and By-laws of the Surviving Corporation shall be
restated to conform to the indemnification provisions set forth in the
Certificate of Incorporation and By-laws, respectively, of the Company, and (c)
the title of the By-laws of the Surviving Corporation shall be amended to read
as follows: "By-laws LUMEN TECHNOLOGIES, INC." The directors of the Purchaser
immediately prior to the Effective Time will be the initial directors of the
Surviving Corporation, and the officers of the Company immediately prior to the
Effective Time will be the initial officers of the Surviving Corporation, in
each case until their successors are elected and qualified.

         2.5      CONVERSION OF SECURITIES; PAYMENT OF MERGER CONSIDERATION.

                  (a)      At the Effective Time, by virtue of the Merger and
without any action on the part of the Purchaser, the Company, the Surviving
Corporation or the holder of any of the following securities:

                           (i)      subject to Section 2.5(b), each Share issued
                  and outstanding immediately prior to the Effective Time (other
                  than Shares to be cancelled pursuant to clause (ii) below and
                  any Dissenting Shares (as defined in Section 2.5(b))) shall be
                  cancelled and extinguished and be converted into and become a
                  right to receive $7.75 net in cash per Share (or any such
                  higher price per Share as may be paid in the Offer) without
                  any interest thereon (the "Merger Consideration");

                           (ii)     each Share that is owned immediately prior
                  to the Effective Time by the Parent, the Purchaser or the
                  Company or any direct or indirect subsidiary of the Parent,
                  the Purchaser or the Company, including all Shares held by the
                  Company as "treasury stock," shall be cancelled and retired,
                  and no payment shall be made with respect thereto; and





                                       -8-


<PAGE>   15
                           (iii)    each share of the Purchaser's capital stock
                  issued and outstanding immediately prior to the Effective Time
                  shall be converted into and become one validly issued, fully
                  paid and nonassessable share of the same class of capital
                  stock of the Surviving Corporation.

                  (b)      (i)      If, pursuant to the Delaware Law, an
affirmative vote of the Company's stockholders is required to approve the
Merger, then notwithstanding Section 2.5(a), Shares outstanding immediately
prior to the Effective Time and held by a holder who, acting in accordance with
Section 262 of the Delaware Law, (A) prior to the meeting at which the Company's
stockholders vote to approve the Merger, has delivered to the Company written
notice of such holder's intention to demand payment of the fair value of his
Shares if the Merger is effectuated and (B) has not voted in favor of the Merger
or consented thereto in writing ("Dissenting Shares"), shall not be converted
into a right to receive the Merger Consideration, unless such holder withdraws
or otherwise loses his right to demand payment for his Shares. If after the
Effective Time such holder withdraws or loses his right to demand payment for
his Shares, such Shares shall be treated as if they had been converted as of the
Effective Time into the right to receive the Merger Consideration payable in
respect of such Shares pursuant to Section 2.5(a)(i).

                           (ii)     If, after consummation of the Offer, the
Purchaser is not required under the Delaware Law to obtain the consent of the
other stockholders of the Company in order to effect the Merger and effects the
Merger without holding a meeting of the stockholders, then, after consummating
the Merger, the Purchaser will provide notice, as required by the Delaware Law,
that it has consummated the Merger and that stockholders are entitled to
exercise their dissenters' rights. Shares of any stockholders who thereafter
fail to perfect or preserve their dissenter's rights under the Delaware Law will
be treated as if such Shares had been converted as of the Effective Time into
the right to receive the Merger Consideration payable in respect of such Shares
pursuant to Section 2.5(a)(i).

                           (iii)    The Company shall give the Parent and the
Purchaser prompt notice of any demands for payment, or notices of intent to
demand payment, received by the Company with respect to Shares, and the Parent
and the Purchaser shall have the right to participate in and direct all
negotiations and proceedings with respect to such demands. The Company shall
not, except with the prior written consent of the Parent and the Purchaser or as
otherwise required by law, make any payment with respect to, or settle, or offer
to settle, any such demands.

         2.6      EXCHANGE OF CERTIFICATES.

                  (a)      Upon the Effective Time, a bank or trust company to
be designated by the Parent (the "Payment Agent") shall act as payment agent in
effecting the exchange, for the Merger Consideration multiplied by the number of
Shares formerly represented thereby, of certificates (the "Certificates") that,
prior to the Effective Time, represented Shares entitled to payment pursuant to
Section 2.5(a)(i). Upon the Effective Time, the Parent shall, or shall





                                       -9-


<PAGE>   16
cause the Purchaser to, deposit with the Payment Agent in trust for the benefit
of the holders of Certificates, as needed to pay for surrendered Shares as
provided in this Section 2.6, within such time as is necessary for the Payment
Agent to make the requisite payments for Shares, immediately available funds in
an aggregate amount (the "Payment Fund") equal to the product of the Merger
Consideration multiplied by the number of Shares entitled to payment pursuant to
Section 2.5(a)(i). Promptly after the Effective Time, the Parent or the
Purchaser shall cause to be mailed to each record holder of Certificates that
immediately prior to the Effective Time represented Shares a form of letter of
transmittal and instructions for use in surrendering such Certificates and
receiving the Merger Consideration therefor. Upon the surrender of each such
Certificate together with a duly completed and executed letter of transmittal,
the Payment Agent shall promptly pay the holder of such Certificate the Merger
Consideration multiplied by the number of Shares formerly represented by such
Certificate, without any interest thereon, in exchange therefor, and such
Certificate shall forthwith be cancelled. Until so surrendered and exchanged,
each such Certificate (other than Certificates representing Shares held by the
Parent, the Purchaser or the Company or any direct or indirect subsidiary of the
Parent, the Purchaser or the Company or Dissenting Shares) shall represent
solely the right to receive the Merger Consideration multiplied by the number of
Shares represented by such Certificate, without any interest thereon. If any
cash is to be paid to a person other than the holder in whose name the
Certificate representing Shares surrendered in exchange therefor is registered,
it shall be a condition to such payment that the person requesting such payment
shall pay to the Payment Agent any transfer or other taxes required by reason of
the payment of such cash to a person other than the registered holder of the
Certificate surrendered, or such person shall establish to the satisfaction of
the Payment Agent that such tax has been paid or is not applicable.
Notwithstanding the foregoing, neither the Payment Agent nor any party hereto
shall be liable to a holder of Shares for any Merger Consideration delivered to
a public official pursuant to applicable abandoned property, escheat and similar
laws.

                  (b)      To the extent not immediately required for payment
for surrendered Shares as provided in Section 2.6(a), the Payment Fund shall be
invested by the Payment Agent, as directed by the Parent (so long as such
directions do not impair the rights of holders of Shares or the ability of the
Payment Agent to timely pay the Merger Consideration), in direct obligations of
the United States of America, obligations for which the full faith and credit of
the United States of America is pledged to provide for the payment of principal
and interest, commercial paper rated of the highest quality by Moody's Investors
Services, Inc. or Standard & Poor's Corporation, or certificates of deposit
issued by a commercial bank having at least $300,000,000 in assets (a "Qualified
Commercial Bank"); and any net earnings with respect thereto shall be paid to
the Parent as and when requested by the Parent.

                  (c)      The Payment Agent shall, pursuant to irrevocable
instructions, make the payments referred to in Section 2.5(a)(i) out of the
Payment Fund. Promptly following the date that is six months after the date of
the Effective Time, the Payment Agent shall deliver to the Parent all cash,
certificates and other documents in its possession relating to the 




                                      -10-
<PAGE>   17

transactions described in this Agreement, and the Payment Agent's duties shall
terminate. Thereafter, each holder of a Certificate formerly representing a
Share may surrender such Certificate to the Surviving Corporation or the Parent
and (subject to applicable abandoned property, escheat and similar laws) receive
in exchange therefor the Merger Consideration, without any interest thereon, but
shall have no greater rights against the Surviving Corporation or the Parent
than may be accorded to general creditors of the Surviving Corporation or the
Parent under applicable law.

                  (d)      After the Effective Time, there shall be no transfers
on the stock transfer books of the Surviving Corporation of any Shares. If,
after the Effective Time, Certificates formerly representing Shares are
presented to the Surviving Corporation or the Payment Agent, they shall be
cancelled and exchanged for the Merger Consideration, as provided in this
Article 2, subject to applicable law in the case of Dissenting Shares.

                  (e)      From and after the Effective Time, holders of
Certificates theretofore evidencing Shares shall cease to have any rights as
stockholders of the Company, except as provided herein or by law.

                  (f)      In the event any Certificate evidencing Shares shall
have been lost, stolen or destroyed, the Paying Agent shall pay to such holder
the Merger Consideration required pursuant to Section 2.5(a)(i), in exchange for
such lost, stolen or destroyed Certificates, upon the making of an affidavit of
that fact by the holder thereof with such assurances as the Parent, in its
discretion and as a condition precedent to the payment of the Merger
Consideration, may reasonably require of the holder of such lost, stolen or
destroyed Certificates. 


                  (g)      The Parent and the Surviving Corporation shall be
entitled to deduct and withhold from the Merger Consideration otherwise payable
pursuant to this Agreement such amounts as may be required to be deducted and
withheld with respect to the making of such payment under the Code, or under any
applicable law.


                                    ARTICLE 3
                         REPRESENTATIONS AND WARRANTIES
                         OF THE PARENT AND THE PURCHASER

         The Parent and the Purchaser each represents and warrants to the

         3.1      ORGANIZATION AND QUALIFICATION. Each of the Parent and the
Purchaser is a corporation duly organized, validly existing and in good standing
under the laws of its state of incorporation and has all requisite corporate
power and authority to carry on its business as it is now being conducted. Each
of the Parent and the Purchaser is duly qualified as a foreign corporation to do
business, and is in good standing, in each jurisdiction where the character of
its properties owned or leased or the nature of its activities makes such
qualification necessary, except for failures to be so qualified or in good
standing which would not, in the





                                      -11-
<PAGE>   18

aggregate, materially impair the ability of the Parent or the Purchaser to
perform its obligations hereunder.

         3.2      AUTHORITY. Each of the Parent and the Purchaser has all
requisite corporate power and authority to enter into this Agreement, to perform
its obligations hereunder and to consummate the transactions contemplated
hereby. The execution and delivery of this Agreement by the Parent and the
Purchaser and the consummation by the Parent and the Purchaser of the
transactions contemplated hereby have been duly authorized by the respective
Boards of Directors of the Parent and the Purchaser and by the Parent as the
sole stockholder of the Purchaser and no other corporate proceedings on the part
of the Parent or the Purchaser are necessary to authorize the execution,
delivery and performance of this Agreement and the transactions contemplated
hereby. This Agreement has been duly executed and delivered by the Parent and
the Purchaser and, assuming this Agreement constitutes a valid and binding
obligation of the other parties hereto, constitutes a valid and binding
obligation of each of them, enforceable against each of them in accordance with
its terms, subject to the effect of any applicable bankruptcy, moratorium,
insolvency, reorganization or other similar law affecting the enforceability of
creditors' rights generally and to the effect of general principles of equity
which may limit the availability of remedies (whether in a proceeding at law or
in equity).

         3.3      COMPLIANCE.

                  (a)      Neither the execution and delivery of this Agreement
by the Parent and the Purchaser, nor the consummation by them of the
transactions contemplated hereby, nor compliance by them with any of the
provisions hereof will (i) violate, conflict with, or result in a breach of any
provision of, or constitute a default (or an event that, with notice or lapse of
time or both, would constitute a default) under, or result in the termination
of, or accelerate the performance or payment required by, or result in a right
of termination or acceleration under, or result in the creation of any lien,
security interest, charge or encumbrance upon any of the properties or assets of
the Parent or the Purchaser or any other direct or indirect subsidiary of the
Parent under, any of the terms, conditions or provisions of (x) the charter
documents or by-laws of the Parent or the Purchaser or any other direct or
indirect subsidiary of the Parent or (y) any note, bond, mortgage, indenture,
deed of trust, license, lease, distribution agreement, joint venture agreement
or any other agreement or instrument or obligation to which the Parent or the
Purchaser or any other direct or indirect subsidiary of the Parent is a party,
or to which any of them, or any of their respective properties or assets, may be
subject, or (ii) subject to compliance with the statutes and regulations
referred to in the next paragraph, violate any judgment, ruling, order, writ,
injunction, decree, statute, rule or regulation applicable to the Parent or the
Purchaser or any other direct or indirect subsidiary of the Parent or any of
their respective properties or assets; except, in the case of each of clause (i)
and (ii) above, for such violations, conflicts, breaches, defaults,
terminations, accelerations or creations of liens, security interests, charges
or encumbrances that, in the aggregate, would not materially impair the ability
of the Parent and the Purchaser to perform their obligations hereunder.

<PAGE>   19

                  (b)      Other than in connection with or in compliance with
the provisions of the Delaware Law, the Exchange Act, the "takeover" or "blue
sky" laws of various states and the Hart-Scott-Rodino Antitrust Improvements Act
of 1976 and the rules and regulations thereunder (the "Hart-Scott-Rodino Act"),
and except for any notices, filings, authorizations, consents or approvals which
are required because of the regulatory status of the Company and its
Subsidiaries (as defined in Section 4.2) or facts specifically pertaining to
them, no notice to, filing with, or authorization, consent or approval of, any
domestic or foreign public body or authority is necessary for the consummation
by the Parent or the Purchaser of the transactions contemplated by this
Agreement, unless the failure to give such notices, make such filings, or obtain
such authorizations, consents or approvals would not, in the aggregate,
materially impair the ability of the Parent and the Purchaser to perform their
obligations hereunder.

         3.4      INFORMATION PROVIDED. Any written information provided by or
on behalf of the Parent or the Purchaser for inclusion in the Schedule 14D-9
(including the Schedule 14f that is a part thereof), on the date the Schedule
14D-9 is filed with the Commission, and on the date the Schedule 14D-9 is first
published, sent or given to stockholders of the Company, will not contain any
untrue statement of a material fact or omit to state any material fact required
to be stated therein or necessary in order to make the statements therein, in
light of the circumstances under which they were made, not misleading.

         3.5      INTERIM OPERATIONS OF THE PURCHASER. The Purchaser was formed
solely for the purpose of engaging in the transactions contemplated by this
Agreement, has not engaged in any other business activities and has conducted
its operations only as contemplated hereby.

         3.6      FINANCING. At the expiration of the Offer and at the Effective
Time, the Parent and the Purchaser will have available all the funds necessary
to purchase all the Shares pursuant to the Offer and the Merger and to pay all
fees and expenses payable by the Parent or the Purchaser related to the
transactions contemplated by this Agreement.

         3.7      BROKERS. No broker, finder or investment banker is entitled to

Purchaser or any of their respective subsidiaries or affiliates.

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

         Except as set forth on the Disclosure Schedule previously delivered by
the Company to the Parent (the "Disclosure Schedule"), the Company represents
and warrants to the Parent and the Purchaser as follows:





                                      -13-
<PAGE>   20


         4.1      ORGANIZATION AND QUALIFICATION. The Company is a corporation
duly organized, validly existing and in good standing under the laws of the
State of Delaware and has all requisite corporate power and authority to carry
on its business as it is now being conducted. The Company is duly qualified as a
foreign corporation to do business, and is in good standing, in each
jurisdiction where the character of its properties owned or leased or the nature
of its activities makes such qualification necessary, except for failures to be
so qualified or in good standing that, in the aggregate, have not resulted in,
and could not reasonably be expected to result in, a Material Adverse Effect.
For purposes of this Agreement, "Material Adverse Effect" means a material
adverse effect on the condition (financial or other), results of operations,
stockholders' equity, business, assets, properties, liabilities, capitalization
or operations of the Company and its Subsidiaries taken as a whole or prevents
or materially interferes with the ability of the Company to perform its
obligations hereunder or to consummate the transactions contemplated by this
Agreement. Copies of the Certificate of Incorporation and By-Laws of the Company
have heretofore been delivered to the Parent and such copies are accurate and
complete. The Company's original Certificate of Incorporation contains a
provision expressly electing not to be governed by Section 203 of the Delaware
Law and such election is in full force and effect such that Section 203 of the
Delaware Law is inapplicable to any of the transactions contemplated by this
Agreement. The resolution of the Company's Directors referred to in Section
1.3(c) is in full force and effect and has not been amended or modified.

         4.2      SUBSIDIARIES.

                  (a)      The only direct or indirect subsidiaries of the
Company (each a "Subsidiary" and collectively, the "Subsidiaries") are those
listed in the Disclosure Schedule.

                  (b)      Each Subsidiary is a corporation duly organized,
validly existing and in good standing under the laws of its jurisdiction of
incorporation and has all requisite corporate power and authority to carry on
its business as it is now being conducted. Each Subsidiary is duly qualified as
a foreign corporation to do business, and is in good standing, in each
jurisdiction where the character of its properties owned or leased or the nature
of its activities makes such qualification necessary, except for failures to be
so qualified or in good standing that, in the aggregate, have not resulted in,
and could not reasonably be expected to result in, a Material Adverse Effect.
Copies of the charter documents and by-laws of each Subsidiary have heretofore
been made available to the Parent and such copies are accurate and complete.

                  (c)      Except for directors' qualifying shares, if any (all
of which the Company has the power to cause to be transferred for no or nominal
consideration to the Purchaser or the Purchaser's designee), the Company is,
directly or indirectly, the record and beneficial owner of all of the
outstanding shares of capital stock in each of the Subsidiaries, there are no
irrevocable proxies with respect to such shares, and no securities of any of the
Subsidiaries are or may become required to be issued by reason of any options,
warrants, scrip, rights to subscribe to, calls or commitments of any character
whatsoever relating to, or securities or 





                                      -14-
<PAGE>   21

rights convertible into or exchangeable for, shares of any capital stock of any
Subsidiary, and there are no contracts, commitments, understandings or
arrangements by which any Subsidiary is bound to issue additional shares or
purchase shares of its capital stock or securities convertible into or
exchangeable for such shares. All of such shares so owned by the Company are
validly issued, fully paid and nonassessable and are owned by the Company free
and clear of any claim, lien, encumbrance or agreement of any kind with respect
thereto.

                  (d)      Except for the Subsidiaries, the Company does not
directly or indirectly own any equity or similar or other interest in, or any
interest convertible into or exchangeable or exercisable for any equity or
similar or other interest in, any other corporation, partnership, joint venture,
limited liability company or other business association or entity, other than
any interests with an individual value of less than $250,000 and an aggregate
value of less than $1,000,000 and which do not require any future payments or
impose any other liabilities or obligations on the part of the Company or any of
its Subsidiaries.

         4.3      CAPITALIZATION.

                  (a)      The authorized capital stock of the Company consists
of 50,000,000 shares of Common Stock, $.01 par value, and 500,000 shares of
Preferred Stock, $1.00 par value (the "Preferred Stock"), of which 10,000 shares
of Preferred Stock are designated as Series A Preferred Stock and 490,000 shares
are undesignated. As of the date of this Agreement (except in the case of clause
(iii) below, which is stated as of the day prior to the date of this Agreement):

                           (i)      20,710,606 Shares are issued and 20,209,606
                                    Shares are issued and outstanding;

                           (ii)     501,000 Shares are held in the treasury of
                                    the Company;

                           (iii)    3,613,325 Shares are reserved for issuance
                                    pursuant to outstanding Options (the
                                    "Company Options") heretofore granted under
                                    the Company's Amended and Restated 1996
                                    Stock Incentive Plan (the "Option Plan");

                           (iv)     no Shares are reserved for issuance in
                                    connection with the Company's 1996 Employee
                                    Stock Purchase Plan (the "ESPP");

termination or acceleration under, or result in the creation of any lien,

judgment, ruling, order, writ, injunction, decree, statute, rule or regulation
applicable to the Company or any of its Subsidiaries or any of their respective
properties or assets; except, in the case of each of clauses (i)(y) and (ii)
above, for such violations, conflicts, breaches, defaults, terminations,
accelerations or creations of liens, security interests, charges or encumbrances
that, in the aggregate, have not resulted in, and could not reasonably be
expected to result in, a Material Adverse Effect.

                  (b)      Other than in connection with or in compliance with
the provisions of the Delaware Law, the Exchange Act, the "takeover" or "blue

conducted their respective businesses only in the ordinary and usual course
consistent with past practice, and none of the following has occurred:

                  (a)      any adverse change in the condition (financial or

the announcement or performance of this Agreement and the transactions
contemplated hereby;

                  (b)      any damage, destruction or loss, whether or not

                  (c)      any reevaluation by the Company or any of its

                  (d)      any action or event listed in Section 5.1; or

                  (e)      any agreement by the Company to do any of the things
described in the preceding clauses (a) through (d) other than as expressly
contemplated or provided for herein.

         4.9      CONTRACTS.

                  (a)      Except as identified on the exhibit indices of the
Commission Filings, there are no contracts or agreements that are material
contracts (as defined in Item 601(b)(10) of Regulation S-K) with respect to the
Company and its Subsidiaries. Neither the Company




                                      -19-
<PAGE>   26

nor any of its Subsidiaries is in violation of or in default under (nor does
there exist any condition which, upon the passage of time or the giving of
notice or both, would cause such a violation of or default under) any material
lease, permit, concession, franchise, license or any other contract or agreement
to which it is a party or by which it or any of its properties or assets is
bound, except for violations or defaults that, in the aggregate, have not
resulted in, or could not reasonably be expected to result in, a Material
Adverse Effect.

                  (b)      Section 4.9(b) of the Disclosure Schedule sets forth
a complete list of each contract or agreement to which the Company or any
Subsidiary is a party or bound (A) with any affiliate of the Company (other than
any Subsidiary which is a direct or indirect wholly owned subsidiary of the
Company), other than any agreements which are or have been fully performed and
under which neither the Company nor any Subsidiary has any continuing liability
or obligation, or (B) that includes any non-competition or similar provision
imposing any restrictions or undertakings on the Company or any Subsidiary,
other than any non-competition or similar provision relating solely to the eye
wear and/or lens grinding business. Copies of all the agreements, contracts and
arrangements set forth in Section 4.9(b) of the Disclosure Schedule have
heretofore been made available to the Parent and such copies are accurate and
complete.

         4.10     TRANSACTIONS WITH AFFILIATES. Except as set forth in the
Commission Filings, since December 28, 1995, neither the Company nor any of its
Subsidiaries has entered into any transaction with any director, officer or
other affiliate of the Company or any Subsidiary or any transaction which would
be subject to disclosure pursuant to Item 404 of Regulation S-K.

         4.11     EMPLOYEE BENEFITS AND CONTRACTS. Except as set forth in
Schedule 4.11(b) of the Disclosure Schedule:

                  (a)      Neither the Company nor any ERISA Affiliate maintains
or contributes to, or has any material obligation under, any Employee Benefit
Plans other than those identified on Schedule 4.11(b) of the Disclosure
Schedule. For the purposes of this Section 4.11, "ERISA" means the Employee
Retirement Income Security Act of 1974, as amended from time to time, and any
successor statute and all rules and regulations promulgated thereunder; "ERISA
Affiliate," as applied to the Company, means any person or trade or business
which is a member of a group which is under common control with the Company, who
together with the Company, is treated as a single employer within the meaning of
Section 414(b) and (c) of the Code; and "Employee Benefit Plan" means any
employee benefit plan within the meaning of Section 3(3) of ERISA which (a) is
maintained for employees of the Company or has been assumed by the Company in
connection with any acquisition or any of its ERISA Affiliates or (b) has at any
time since October 16, 1992 been maintained for the employees of the Company or
any current or former ERISA Affiliate.

                  (b)      The Company and each ERISA Affiliate is in compliance
with all applicable provisions of ERISA and the regulations and published
interpretations thereunder 




                                      -20-
<PAGE>   27

and in compliance with all Foreign Benefit Laws with respect to all Employee
Benefit Plans, except for failures to comply that in the aggregate have not
resulted in, and could not reasonably be expected to result in, a Material
Adverse Effect and except for any required amendments for which the remedial
amendment period as defined in Section 401(b) of the Code has not yet expired.
Each Employee Benefit Plan that is intended to be qualified under Section 401(a)
of the Code has been determined by the Internal Revenue Service to be so
qualified, and each trust related to such plan has been determined to be exempt
under Section 501(a) of the Code. No material liability has been incurred by the
Company or any ERISA Affiliate which remains unsatisfied for any taxes or
penalties with respect to any Employee Benefit Plan. For the purposes of this
Section 4.11, "Foreign Benefit Law" means any applicable statute, law,
ordinance, code, rule, regulation, order or decree of any foreign nation or any
province, state, territory, protectorate or other political subdivision thereof
regulating, relating to, or imposing liability or standards of conduct
concerning, any Employee Benefit Plan.

                  (c)      Neither the Company nor any affiliate is a party to
any collective bargaining agreement. Neither the Company nor any affiliate has
ever (i) maintained an Employee Benefit Plan subject to Section 412 of the Code
or Title IV of ERISA, or (ii) had an obligation to contribute to a
"multiemployer plan" as defined in Section 4001(a)(3) of ERISA.

                  (d)      Neither the Company nor any ERISA Affiliate has
engaged in a nonexempt prohibited transaction described in Section 406 of ERISA
or Section 4975 of the Code.

                  (e)      There are no unfunded obligations under any Employee
Benefit Plan of the Company or any affiliate providing benefits after
termination of employment to any employee or former employee, including but not
limited to retiree health coverage and deferred compensation but excluding
continuation of health coverage required to be continued under Section 4980(B)
of the Code. Each Employee Benefit Plan of the Company, any Subsidiary or any of
their respective affiliates may be amended or terminated by the Company, such
Subsidiary or such affiliate without the consent or approval of any other person
and without any termination fees, market value adjustments, surrender charges or
other costs. There is no employment agreement, Employee Benefit Plan, stock
option plan, stock appreciation right plan, restricted stock plan, stock
purchase plan, or severance benefit plan of the Company or any affiliate, any of
the benefits of which will be increased, or the vesting of the benefits of which
will be accelerated by the occurrence of any of the transactions contemplated by
this Agreement or the benefits under which will be due as a result of or
calculated on the basis of the transactions contemplated by this Agreement.

                  (f)      No material proceeding, claim, lawsuit and/or
investigation exists or to the best knowledge of the Company after due inquiry,
is threatened concerning or involving any Employee Benefit Plan.

         4.12     PROPERTIES AND LIENS.

                  (a)      All real property owned or leased by the Company or
any Subsidiary is listed on the Disclosure Schedule, other than real property
with a cost or fair market value of less than $10,000.

                  (b)      Each of the Company and its Subsidiaries has good and
valid title to, or valid leasehold interests in or valid rights to, all of its
material tangible properties and assets (personal and real) reflected in the
balance sheet for the period ended September 30, 1998 included in the September
30 Financial Information, except for such as have been disposed of in the
ordinary course of business since September 30, 1998. All such material tangible
assets and properties, other than assets and properties in which the Company or
any Subsidiary has a leasehold interest, are free and clear of all mortgages,
security interests, pledges, liens and encumbrances ("Liens"), except for Liens
that, in the aggregate, do not materially interfere with the ability of the
Company and its Subsidiaries to conduct their business as currently conducted
and have not resulted in, and could not reasonably be expected to result in, a
Material Adverse Effect.

                  (c)      Each of the Company and each Subsidiary has complied
in all material respects with the term of all material leases for real or
personal property to which it is a party, and all such leases are in full force
and effect. Each of the Company and each Subsidiary enjoys peaceful and
undisturbed possession under all such material leases, except for failures to do
so that, in the aggregate, have not resulted in, and could not reasonably be
expected to result in, a Material Adverse Effect.

                  (d)      The properties and assets of the Company and its
Subsidiaries, taken as a whole, are free from material defects, have been
maintained in accordance with normal industry practice, are in good operating
condition and repair (subject to normal wear and tear) and are suitable for the
purposes for which they are presently used.

         4.13     ENVIRONMENTAL MATTERS.

                  (a) The Company and the Subsidiaries are in compliance with
and have complied with all applicable Environmental Laws (as defined below),
except for failures to comply that, in the aggregate, have not resulted in, and
could not reasonably be expected to result in, a Material Adverse Effect. There
is no pending or, to the best knowledge of the Company, threatened civil or
criminal litigation, written notice of violation, formal administrative
proceedings or investigations, inquiries or information requests by any court,
arbitration tribunal, administrative agency or commission or other governmental
or regulatory authority or agency, domestic, foreign or supranational (a
"Governmental Entity"), relating to 




                                      -22-
<PAGE>   29

any Environmental Law involving the Company or any of its Subsidiaries the
adverse resolution of which would, either singularly or in the aggregate, result
in, or could reasonably be expected to result in, a Material Adverse Effect. For
purposes of this Agreement, "Environmental Law" means any foreign, federal,
state, local or supranational law, statute, rule or regulation or the common law
relating to the environment or occupational health and safety, including without
limitation, any statute, regulation or order pertaining to (i) treatment,
storage, disposal, generation or transportation of industrial, toxic or
hazardous substances or solid or hazardous waste; (ii) air, water and noise
pollution; (iii) groundwater and soil contamination; (iv) the release or
threatened release into the environment of industrial, toxic or hazardous
substances, or solid or hazardous waste, including emissions, discharges,
injections, spills, escapes or dumping of pollutants, contaminants or chemicals;
(v) the protection of wild life, marine sanctuaries and wetlands, including all
endangered and threatened species; (vi) underground and other storage tanks or
vessels, abandoned, disposed or discarded barrels, containers and other closed
receptacles; (vii) health and safety of employees and the public; and (viii)
manufacture, processing, use, distribution, treatment, storage, disposal,
transportation or handling of pollutants, contaminants, chemicals or industrial,
toxic or hazardous substances or oil or petroleum products or solid or hazardous
waste. As used in this Section 4.13, the terms "release" and "environment" shall
have the meaning set forth in the federal Comprehensive Environmental
Compensation, Liability and Response Act of 1980 ("CERCLA"). As used above, the
phrase "investigation, inquiry or information request" includes, but is not
limited to, any Notice of Responsibility or Section 104(e) Information Request
issued pursuant to CERCLA or to any similar state law addressing the
investigation and/or remediation of any environmental contamination.

                  (b)      There have been no releases of any Materials of
Environmental Concern (as defined below) into the environment by the Company or
any of its Subsidiaries, or, to the best knowledge of the Company, by any other
party at any parcel of real property or any facility formerly or currently
owned, operated or controlled by the Company or any of its Subsidiaries that, in
the aggregate, have resulted in, or could reasonably be expected to result in, a
Material Adverse Effect. With respect to any such releases of Materials of
Environmental Concern, the Company has given all notices required to be given by
the Company or any of its Subsidiaries to Governmental Entities. The Company has
no actual knowledge of any releases of Materials of Environmental Concern at
parcels of real property or facilities other than those owned, operated or
controlled by the Company or any of its Subsidiaries that, in the aggregate,
have, or could reasonably be expected to have, a material impact on the real
property or facilities owned, operated or controlled by the Company or any of
its Subsidiaries or that have resulted in, or could reasonably be expected to
result in, a Material Adverse Effect. For purposes of this Agreement, "Materials
of Environmental Concern" means any chemicals, pollutants or contaminants,
hazardous substances (as such term is defined under CERCLA), solid wastes and
hazardous wastes (as such terms are defined under the federal Resources
Conservation and Recovery Act), toxic materials, oil or petroleum and petroleum
products, or any other material subject to regulation under any Environmental
Law.

                  (c)      Set forth in the Disclosure Schedule is a list of all
material environmental reports, investigations and audits conducted by or on
behalf of the Company or any of its Subsidiaries or, to the best knowledge of
the Company, conducted by or on behalf of a third party (whether done at the
initiative of the Company or directed by a Governmental Entity or other third
party) issued or conducted during the past five years relating to premises
currently owned or operated by the Company or any of its Subsidiaries. Copies of
each such report, or the results of each such investigation or audit, have
heretofore been made available to the Parent and such copies are accurate and
complete, except that the Company makes no representation as to the accuracy or
completeness of any reports prepared by or for third parties.

                  (d)      To the best knowledge of the Company, there is no
material environmental liability of any solid or hazardous waste transporter or
treatment, storage or disposal facility that has been utilized by the Company or
any of its Subsidiaries, which have resulted in, or could reasonably be expected
to result in, either singularly or in the aggregate, a Material Adverse Effect.

                  (e)      The Company and the Subsidiaries have all requisite
licenses, permits, certificates, permits-by-rule and approvals under the
Environmental Laws from Governmental Entities necessary to conduct its business
and operate its assets (collectively, the "Environmental Permits"), except for
such licenses, permits, certificates, permits-by-rule and approvals the absence
of which, in the aggregate, have not resulted in, and could not reasonably be
expected to result in, a Material Adverse Effect. No Environmental Permit will
cease to be effective as a result of the consummation of transactions
contemplated by this Agreement. The Environmental Permits do not contain
restrictions, limitations or other terms or conditions that will restrict the
ability of the Surviving Corporation to continue to operate its business
subsequent to the Effective Time in substantially the same manner as it is
currently being operated.

                  (f)      To the best knowledge of the Company, neither the
Company nor any of its Subsidiaries have assumed any liability, responsibility,
commitment or obligation under any Environmental Law arising in any way from the
existence or operation of any company, organization or entity that is or was a
predecessor to the Company or any of its Subsidiaries, which liability,
responsibility, commitment or obligation has resulted in, or could reasonably be
expected to result in, a Material Adverse Effect.

                  (a)      Except as set forth in Section 4.14(a) of the
Disclosure Schedule, each of the Company and the Subsidiaries has filed all Tax
Returns (as defined below) that it was required to file, and all such Tax
Returns were complete and accurate in all material respects. Except as set forth
in Section 4.14(a) of the Disclosure Schedule, neither the Company nor any
Subsidiary is or has ever been a member of a group of corporations with which it
has filed (or been required to file) consolidated, combined or unitary Tax
Returns, other than a 




                                      -24-

group of which only the Company and the Subsidiaries are or were members. To the
best knowledge of the Company, each group of corporations with which the Company
or any Subsidiary has filed (or was required to file) consolidated, combined,
unitary or similar Tax Returns (an "Affiliated Group") has filed all material
Tax Returns that it was required to file with respect to any period in which the
Company or a Subsidiary was a member of such Affiliated Group (an "Affiliated
Period"), and all such Tax Returns were complete and accurate in all material
respects. Each of the Company and the Subsidiaries has paid on a timely basis
all Taxes (as defined below) that were shown to be due and payable on such Tax
Returns and, to the best knowledge of the Company, each Affiliated Group has
paid all Taxes that were shown to be due and payable on such Tax Returns with
respect to all such Tax Returns filed for Affiliated Periods, except in either
case for failures to pay Taxes that, in the aggregate, have not resulted in, and
could not reasonably be expected to result in, a Material Adverse Effect. The
unpaid Taxes of the Company and the Subsidiaries for Tax periods through
September 30, 1998 do not exceed the accruals and reserves for Taxes (excluding
any assets, accruals, and reserves for deferred Taxes established to reflect
timing differences between book and Tax income) set forth on the balance sheet
as of September 30, 1998 referred to in Section 4.6(c) of this Agreement and
included in the Disclosure Schedule. All Taxes that the Company or any
Subsidiary is or was required by law to withhold or collect have been duly
withheld or collected and, to the extent required, have been paid to the proper
taxing authority, except for failures to withhold, collect or pay that, in the
aggregate, have not resulted in, and could not reasonably be expected to result
in, a Material Adverse Effect. For purposes of this Agreement, "Taxes" means all
taxes, charges, fees, levies or other similar assessments or liabilities,
including without limitation income, gross receipts, ad valorem, premium,
value-added, excise, real property, personal property, sales, use, transfer,
withholding, employment, payroll and franchise taxes imposed by the United
States of America or any state, local or foreign government, or any agency
thereof, or other political subdivision of the United States or any such
government, and any interest, fines, penalties, assessments or additions to tax
resulting from, attributable to or incurred in connection with any such tax. For
purposes of this Agreement, "Tax Returns" means all reports, returns,
declarations, statements or other information required to be supplied to a
taxing authority in connection with Taxes.

                  (b)      The Company has made available to the Buyer complete
and accurate copies of all federal income Tax Returns filed by, and examination
reports and statements of deficiencies assessed against or agreed to by, the
Company or any Subsidiary since December 28, 1995. Except as set forth in
Section 4.14(b) of the Disclosure Schedule, the federal income Tax Returns of
the Company and each Subsidiary have been audited by the Internal Revenue
Service or are closed by the applicable statute of limitations for all taxable
years through the taxable year specified in the Disclosure Schedule. The Company
has made available to the Buyer complete and accurate copies of all other Tax
Returns of the Company and the Subsidiaries together with all related
examination reports and statements of deficiency for all periods from and after
December 28, 1995. Except as set forth in Section 4.14(b) of the Disclosure
Schedule, no examination or audit of any Tax Return of the Company or any
Subsidiary by any taxing authority is currently in progress or, to the best
knowledge of the 



                                      -25-

Company, threatened or contemplated, except in either case for matters that, in
the aggregate, have not resulted in, and could not reasonably be expected to
result in, a Material Adverse Effect. Neither the Company nor any Subsidiary has
been informed by any taxing authority that the taxing authority believes that
the Company or Subsidiary was required to file any Tax Return that was not
filed, except for matters that, in the aggregate, have not resulted in, and
could not reasonably be expected to result in, a Material Adverse Effect.
Neither the Company nor any Subsidiary has waived any statute of limitations
with respect to Taxes or agreed to an extension of time with respect to a Tax
assessment or deficiency, except for any waivers and extensions that, in the
aggregate, have not resulted in, and could not reasonably be expected to result
in, a Material Adverse Effect.

                  (c)      Except as set forth in Section 4.14(c) of the
Disclosure Schedule, neither the Company nor any Subsidiary: (i) is a
"consenting corporation" within the meaning of Section 341(f) of the Code, and
none of the assets of the Company or the Subsidiaries are subject to an election
under Section 341(f) of the Code; (ii) has been a United States real property
holding corporation within the meaning of Section 897(c)(2) of the Code during
the applicable period specified in Section 897(c)(l)(A)(ii) of the Code; or
(iii) has any actual or potential liability for any Taxes of any person (other
than the Company and its Subsidiaries) under Treasury Regulation Section
1.1502-6 (or any similar provision of federal, state, local, or foreign law), or
as a transferee or successor, by contract, or otherwise.

                  (d)      None of the assets of the Company or any Subsidiary:
(i) is property that is required to be treated as being owned by any other
person pursuant to the provisions of former Section 168(f)(8) of the Code; (ii)
is "tax-exempt use property" within the meaning of Section 168(h) of the Code;
or (iii) directly or indirectly secures any debt the interest on which is tax
exempt under Section 103(a) of the Code.

                  (e)      Neither the Company nor any Subsidiary has undergone,
or will undergo as a result of the transactions contemplated by this Agreement,
a change in its method of accounting resulting in an adjustment to its taxable
income pursuant to Section 481(a) of the Code.

                  (f)      Except as set forth in Section 4.14(f) of the
Disclosure Schedule, no state or federal "net operating loss" of the Company
determined as of the Effective Time is subject to limitation on its use pursuant
to Section 382 of the Code or comparable provisions of state law as a result of
any "ownership change" within the meaning of Section 382(g) of the Code
occurring prior to the Effective Time.

                  (g)      Except as set forth in Section 4.14(g) of the
Disclosure Schedule, there are no liens for Taxes (other than for current Taxes
not yet due and payable) upon the assets of the Company or any Subsidiary.

                  (h)      Except as set forth in Section 4.14(h) of the
Disclosure Schedule, neither the Company nor any Subsidiary is a party to or
bound by any Tax indemnity, Tax sharing or Tax allocation agreement.

         4.15     COMPLIANCE WITH LAWS; PERMITS. Neither the Company nor any
Subsidiary (a) is in violation of, or has violated, any applicable provisions of
any laws, statutes, ordinances or regulations or (b) has received any notice
from any Governmental Entity or any other person that either the Company or any
Subsidiary is in violation of, or has violated, any applicable provisions of any
laws, statutes, ordinances or regulations, except for violations that, in the
aggregate, have not resulted in, and could not reasonably be expected to result
in, a Material Adverse Effect. The Company and each of its Subsidiaries have all
permits, licenses and franchises from Governmental Entities required to conduct
their businesses as now being conducted or as presently contemplated to be
conducted, except for such permits, licenses and franchises the absence of
which, in the aggregate, have not resulted in, and could not reasonably be
expected to result in, a Material Adverse Effect.

         4.16     INTELLECTUAL PROPERTY. The Company, or a Subsidiary, has
exclusive ownership of or rights to use each patent, patent application,
copyright (whether or not registered), copyright application, trademark (whether
or not registered), trademark application, trade name, service mark, and other
trade secret or proprietary intellectual property (collectively, "Intellectual
Property") owned by or used in and material to the business of the Company and
the Subsidiaries, taken as a whole. The Disclosure Schedule sets forth a
description of all patents, trademarks and copyrights and applications therefor
owned by or licensed to the Company or any Subsidiary that are material to the
conduct of the business of the Company and the Subsidiaries, taken as a whole,
as now operated. None of the previous or current development, manufacture,
marketing or distribution of products or services of or by the Company or any
Subsidiary infringes the right of any other person, except for any such
infringements that, in the aggregate, have not resulted in, and could not
reasonably be expected to result in, a Material Adverse Effect. To the best
knowledge of the Company, no other person is infringing the rights of the
Company or any Subsidiary in any such Intellectual Property, except for any such
infringements that, in the aggregate, have not resulted in, and could not
reasonably be expected to result in, a Material Adverse Effect.

         4.17     LITIGATION. There are no actions, suits, proceedings or
investigations pending or, to the best knowledge of the Company, threatened
against the Company or any of its Subsidiaries, nor is the Company or any of its
Subsidiaries subject to any order, judgment, writ, injunction or decree, except
in either case for matters that, in the aggregate, have not resulted in, and
could not reasonably be expected to result in, a Material Adverse Effect.

         4.18     PREPAYMENT OF INDEBTEDNESS. All of the outstanding
indebtedness (whether secured or unsecured) for borrowed money of the Company
and each of its Subsidiaries may be prepaid by the Company or its Subsidiaries
without the consent or approval of, or prior notice to, any other person, and
without payment of any premium or penalty.

         4.19     VOTING REQUIREMENTS. The affirmative vote of the holders of a
majority of the outstanding Shares is the only vote of the holders of any class
or series of the Company's capital stock or other securities necessary to
approve the Merger. There are no bonds, debentures, notes or other indebtedness
of the Company having the right to vote (or convertible into, or exchangeable
for, securities having the right to vote) on any matters on which stockholders
of the Company may vote.

         4.20     YEAR 2000 COMPLIANCE.

                  (a)      All of (i) the Company's internal systems that are
material to the business or operations of the Company, including, without
limitation, computer hardware systems, software applications and embedded
systems, and (ii) the software, hardware, firmware and other technology which
constitute part of the products and services manufactured, marketed or sold by
the Company or licensed by the Company to third parties are Year 2000 Compliant
(as defined below), except in either case for any failures to be Year 2000
Compliant that in the aggregate have not resulted in, and could not reasonably
be expected to result in, a Material Adverse Effect. The Company is not aware of
any failure to be Year 2000 Compliant of any third-party system that is material
to the business or operations of the Company, including without limitation any
system belonging to any of the Company's suppliers, service providers or
customers.

                  (b)      For purposes of this Agreement, "Year 2000 Compliant"
means that the applicable system or item:

                           (i)      will accurately receive, record, store,
                                    provide, recognize and process all date and
                                    time data from, during, into and between the
                                    twentieth and twenty-first centuries, the
                                    years 1999 and 2000 and all leap years;

                           (ii)     will accurately perform all date-dependent
                                    calculations and operations (including,
                                    without limitation, mathematical operations,
                                    sorting, comparing and reporting) from,
                                    during, into and between the twentieth and
                                    twenty-first centuries, the years 1999 and
                                    2000 and all leap years; and

                           (iii)    will not malfunction, cease to function or
                                    provide invalid or incorrect results as a
                                    result of (x) the change of years from 1999
                                    to 2000, (y) date data, including date data
                                    which represents or references different
                                    centuries, different dates during 1999 and
                                    2000, or more than one century or (z) the
                                    occurrence of any particular date;

in each case without human intervention, other than original data entry;
provided, in each case, that all applications, hardware and other systems used
in conjunction with such system 



                                      -28-

or item which are not owned or licensed by the Company correctly exchange date
data with or provide data to such system or item.

         4.21     INSURANCE. The Company maintains insurance policies (the
"INSURANCE POLICIES") against all risks of a character and, to the Company's
best knowledge, in such amounts as are usually insured against by similarly
situated companies in the same or similar businesses. Each Insurance Policy is
in full force and effect and is valid, outstanding and enforceable, and all
premiums due thereon have been paid in full. To the Company's best knowledge,
none of the Insurance Policies that are material to the business of the Company
and its Subsidiaries taken as a whole will terminate or lapse (or be affected in
any other materially adverse manner) by reason of the transactions contemplated
by this Agreement. The Company and its Subsidiaries have complied in all
material respects with the provisions of each Insurance Policy under which it is
the insured party. Since January 1, 1996, no insurer under any Insurance Policy
that is material to the business of the Company and its Subsidiaries taken as a
whole has, in writing, canceled or generally disclaimed liability under any such
policy or indicated any intent to do so or not to renew any such policy. All
material claims under the Insurance Policies have been filed in a timely
fashion.

         4.22     NO EXISTING DISCUSSION. As of the date hereof, the Company has
ceased any and all discussions or negotiations with any other party with respect
to an Acquisition Proposal (as defined in Section 6.5).

         4.23     BROKERS. No broker, finder or investment banker other than the
Financial Advisor is entitled to any brokerage, finder's or other fee or
commission in connection with the Offer or the Merger based upon arrangements
made by or on behalf of the Company or any of its Subsidiaries or affiliates.
The Company has provided to the Parent a true and complete copy of its entire
agreement with the Financial Advisor.

                               CONDUCT OF BUSINESS

entering into or as expressly contemplated by this Agreement or any Disclosure
Schedule relating to this Article 5, the Company covenants and agrees that,
unless the Parent shall otherwise agree in writing, prior to the Effective Time,
the business of the Company and its Subsidiaries shall in all material respects
be conducted only in, and the Company and its Subsidiaries shall not take any
material action except in, the ordinary course of business and consistent with
past practice, and the Company shall use all reasonable efforts, consistent with
past practice, to maintain and preserve its and each Subsidiary's business
organization, assets, employees and advantageous business relationships. Without
limiting the generality of the foregoing, during the period from the date of
this Agreement until the Effective Time, except as a result of entering into or

relating to this Article 5, the Company shall not, and not permit any of its
Subsidiaries to, directly or indirectly, do any of the following:

                  its parent: (A) declare, set aside or pay any dividends on, or
                  make any other distributions (whether in cash, stock or other
                  property) in respect of, any of its capital stock; (B) split,
                  combine or reclassify any of its capital stock or issue or
                  authorize the issuance of any other securities in respect of,
                  in lieu of or in substitution of shares of its capital stock;
                  or (C) purchase, redeem or otherwise acquire any shares of its
                  capital stock or any other securities thereof or any rights,

                  securities, other than the payment to holders of Company
                  Options outstanding on the date hereof of an amount equal to
                  the difference between the price per Share to be paid in the
                  Offer and the exercise price of such Company Option in
                  exchange for the cancellation or termination of such Company
                  Option;

                           (ii)     issue, deliver, sell, pledge or otherwise

                  any rights, warrants or options to acquire, any such shares,

                  issuance of Shares upon the exercise of Company Options or
                  conversion of Convertible Notes outstanding on the date of
                  this Agreement in accordance with their present terms);

                  By-laws or other comparable charter or organizational
                  documents;

                           (iv)     acquire or agree to acquire (A) by merging

                  of the assets or any stock of, or by any other manner, any
                  business or any corporation, partnership, joint venture,
                  limited liability company, association or other business
                  organization or division thereof or (B) any assets that are

                  pledge or otherwise dispose of or encumber any assets of the
                  Company or of any of its Subsidiaries (including any
                  indebtedness owned to them or any claims held by them);

                           (vi)     whether or not in the ordinary course of

                  ordinary course of business consistent with past practice);

                           (vii)    except as permitted by Section 6.5, enter
                  into an agreement with respect to any merger, consolidation,
                  liquidation or business combination, or any acquisition or
                  disposition of all or substantially all of the assets or
                  securities of the Company;

                           (viii)   (A) incur or suffer to exist any

                  Indebtedness (as defined below), or guarantee any such
                  indebtedness of another person, issue or sell any debt

                  employees of the Company in the ordinary course of business)
                  or capital contributions to, or investments in, any other
                  person other than between the Company and its Subsidiaries or
                  any of them. For purposes of this Section 5.1, "Permitted
                  Indebtedness" means (I) indebtedness for borrowed money that
                  existed as of September 30, 1998 as reflected on the balance

                              ADDITIONAL AGREEMENTS

         6.1      COMPANY STOCKHOLDER APPROVAL; PREPARATION OF PROXY STATEMENT.

                  (a)      If approval of the Merger by the stockholders of the
Company is required under Delaware Law in order to consummate the Merger, the
Company will, as soon as practicable following the acceptance for payment of,
and payment for, Shares by the Purchaser pursuant to and subject to the
conditions of the Offer (coordinating the timing thereof with the Parent), duly
call, give notice of, convene and hold a special or annual meeting of its
stockholders (the "Stockholders Meeting") for the purpose of obtaining
stockholder approval of this Agreement, the Merger and the transactions
contemplated hereby. Except and to the extent otherwise permitted pursuant to
Section 6.5, the Company will, through its Board of Directors, recommend to its
stockholders that they approve the Merger. Notwithstanding the foregoing, if the
Purchaser or any other subsidiary of the Parent shall acquire at least 90% of
the outstanding Shares, the parties shall, at the request of the Parent, take
all necessary and appropriate action to cause the Merger to become effective as
soon as practicable (but in no event earlier than January 11, 1999, unless
otherwise requested by the Parent) after the expiration of the Offer without a
stockholders meeting in accordance with Section 253 of the DGCL. The Parent and
the Purchaser shall vote or cause to be voted any Shares beneficially owned by
them in favor of this Agreement, the Merger and the transactions contemplated
hereby.

                  (b)      If approval of the Merger by the stockholders of the
Company is required under Delaware Law in order to consummate the Merger, the
Company will, at the Parent's request, as soon as practicable following the
expiration of the Offer, prepare and file a preliminary proxy or information
statement (the "Proxy Statement") with the Commission in accordance with the
Exchange Act and any other applicable laws, and will use its best efforts to
respond to any comments of the Commission or its staff and to cause the Proxy
Statement to be mailed to the Company's stockholders as promptly as practicable
after responding to all such comments to the satisfaction of the Commission or
its staff. The Company will notify the Parent promptly of the receipt of any
comments from the Commission or its staff and of any request by the Commission
or its staff for amendments or supplements to the Proxy Statement or for
additional information and will supply the Parent with copies of all



                                      -33-
<PAGE>   40


correspondence between the Company or any of its representatives, on the one
hand, and the Commission or its staff, on the other hand, with respect to the
Proxy Statement or the Merger. If at any time prior to the Stockholders Meeting
there shall occur any event that should be set forth in an amendment or
supplement to the Proxy Statement, the Company will promptly prepare and mail to
its stockholders and file with the Commission such an amendment or supplement.
The Company will not mail any Proxy Statement, or any amendment or supplement
thereto, to the Company's stockholders unless it has first obtained the consent
of the Parent to such mailing, which consent will not be unreasonably withheld.

         6.2      DISPOSITION OF THE SHARES. The Parent and the Purchaser shall
not, and they shall cause their direct and indirect subsidiaries not to, sell,
transfer, assign, encumber or otherwise dispose of the Shares beneficially owned
by the Parent, the Purchaser or their respective direct or indirect
subsidiaries, as of the date of this Agreement, or acquired pursuant to the
Offer or otherwise prior to the meeting of the Company's stockholders, if any is
required, pursuant to which the Shares are voted with respect to the Merger,
this Agreement and the transactions contemplated hereby; provided, however, that
this Section 6.2 shall not apply to the sale, transfer, assignment, encumbrance
or other disposition of any or all of such Shares in transactions involving
solely the Parent, the Purchaser and/or one or more of their direct or indirect
subsidiaries or in connection with any Qualified Acquisition Proposal (as
defined in Section 6.5).

         6.3      FEES AND EXPENSES.

                  (a)      Except as otherwise provided in this Section 6.3,
each party shall bear all of the fees and expenses incurred by it in connection
with the negotiation and performance of this Agreement, and neither party may
recover any such fees and expenses from the other party upon any termination of
this Agreement.

                  (b)      The Company shall immediately pay to the Parent
$7,450,000 in cash if:

                           (i)      the Trigger Event specified in Section
                  6.3(e)(i) shall have occurred, and the Parent shall have
                  elected to terminate this Agreement pursuant to Section
                  8.1(c)(iii); or

                           (ii)     the Trigger Event specified in Section
                  6.3(e)(ii) shall have occurred; or

                           (iii)    the Company shall have elected to terminate
                  this Agreement pursuant to Section 8.1(b)(v).

                  (c)      In addition to any payment provided for above in this
Section 6.3, if (x) any of the events specified in Section 6.3(b)(i), (ii) or
(iii) shall have occurred or (y) the Parent terminates this Agreement pursuant
to Section 8.1(c)(iv), then, the Company shall




                                      -34-
<PAGE>   41

immediately pay to the Parent an amount equal to the reasonable out-of-pocket
expenses incurred by the Parent and the Purchaser in connection with the
evaluation, negotiation, implementation and consummation of the transactions
contemplated by this Agreement (including fees and expenses of legal counsel,
solicitors, accountants, printers and financial advisors and investment
bankers); PROVIDED, HOWEVER, that, in no event shall the amount payable by the
Company pursuant to this Section 6.3(c) exceed $500,000. The Purchaser and the
Parent shall promptly provide the Company with invoices or other reasonable
evidence of such expenses upon written request by the Company, and the Parent
shall forthwith return any portion of expenses reimbursed by the Company as to
which such invoices or other evidence are not provided.

                  (d)      Nothing contained in this Section 6.3 shall relieve
the Company of its obligation (except and to the extent otherwise permitted
pursuant to Section 6.5 below) to recommend that the Company's stockholders
accept and approve the Offer and the Merger. The provisions contained in this
Section 6.3 shall survive any termination of this Agreement.

                  (e)      As used in this Agreement, the term "Trigger Event"
shall mean any of the following events:

                           (i)      the Company's Directors, whether or not in
                  the exercise of their fiduciary or other legal duties, either
                  (A) shall have failed to approve or recommend, or shall have
                  withdrawn or adversely modified or taken a public position
                  materially inconsistent with its approval or recommendation
                  of, the Offer, the Merger or this Agreement or (B) take any
                  action (other than as expressly permitted under clauses (i)
                  and (ii) of the second sentence of Section 6.5(a)) with
                  respect to any Qualified Acquisition Proposal other than to
                  recommend rejection of the Qualified Acquisition Proposal
                  (including taking a position of neutrality or failing to take
                  any position within 10 business days after the making or
                  commencement of a Qualified Acquisition Proposal); or

                           (ii)     prior to the final expiration of the Offer,
                  an Acquisition Proposal shall have become publicly known and
                  this Agreement is terminated (other than as a result of a
                  material breach of this Agreement by the Parent or the
                  Purchaser) and, within 12 months after such termination, (A)
                  the Company enters into a merger or other agreement that
                  contemplates the consummation of an Acquisition Proposal at a
                  price equal to or greater than the aggregate consideration
                  payable for Shares pursuant to the Offer and the Merger or (B)
                  the holders of Shares become entitled to receive consideration
                  per Share greater than the Merger Consideration in a
                  transaction or series of transactions in connection with an
                  Acquisition Proposal.

         6.4      ADDITIONAL AGREEMENTS. Subject to the terms and conditions
herein provided, each of the parties hereto agrees to use all reasonable efforts
to take, or cause to be taken, all actions and to do, or cause to be done, all
things necessary, proper or advisable to 




                                      -35-
<PAGE>   42
consummate and make effective as promptly as practicable the transactions
contemplated by this Agreement, and to cooperate with each of the other parties
hereto in connection with the foregoing, including using all reasonable efforts:
(A) to obtain all necessary waivers, consents and approvals from other parties
to loan agreements, leases and other contracts; (B) to obtain all necessary
consents, approvals and authorizations as are required to be obtained under any
federal, state or foreign laws or regulations; (C) to lift or rescind any
injunction or restraining order or other order adversely affecting the ability
of the parties to consummate the transactions contemplated hereby; (D) to effect
all necessary registrations and filings, including filings under the Hart-
Scott-Rodino Act and submissions of information requested by governmental
authorities; and (E) to fulfill all conditions to this Agreement. Each of the
Company, the Parent and the Purchaser further covenants and agrees that, prior
to the exercise by the Parent or the Purchaser of the right to terminate the
Offer under paragraphs (c) or (d) of ANNEX I hereto, each of the Company, the
Parent and the Purchaser shall use all reasonable efforts (which shall not be
construed to require the payment of any money to a third party or the
divestiture of or requirement to hold separate (through a trust or otherwise)
any business or assets) to prevent, with respect to a threatened or pending
preliminary or permanent injunction or other order, decree or ruling or statute,
rule, regulation or executive order specified in such paragraphs, the entry,
enactment or promulgation thereof, as the case may be. For purposes of the
foregoing, the obligation of the Parent and the Purchaser to use "all reasonable
efforts" to obtain waivers, consents and approvals to loan agreements, leases
and other contracts shall not include any obligation to agree to a modification
of the terms of such documents, except as expressly contemplated hereby or to
make any guaranty or monetary payment in consideration of such waiver, consent
or approval.

         6.5      NO SOLICITATION.

                  (a)      The Company shall not, and shall not authorize or
permit any of its Subsidiaries, or any of its or their officers, directors,
employees, representatives, agents or affiliates, including any investment
banker, attorney or accountant retained by the Company or any of its
Subsidiaries, to, directly or indirectly, (i) solicit, initiate or encourage
(including by way of furnishing information), or take any other action to
facilitate, any inquiries or the making of any proposal or offer that
constitutes, or may reasonably be expected to lead to, any Acquisition Proposal
(as defined below) or (ii) enter into, maintain, continue or otherwise
participate in any discussions or negotiations regarding any Acquisition
Proposal with any person, entity or group other than the Parent, the Purchaser
or their respective direct or indirect subsidiaries or affiliates (a "Third
Party"). Notwithstanding the foregoing, the Company, its Subsidiaries, and their
respective officers, directors, employees, representatives, agents and
affiliates, including any investment banker, attorney or accountant retained by
the Company or any of its Subsidiaries, may (i), in the case of a Qualified
Acquisition Proposal (as defined below) only, furnish or cause to be furnished
information concerning the Company's business, properties or assets to a Third
Party (subject to such Third Party executing a confidentiality agreement on
terms no less favorable to the Company than those in the confidentiality
agreement previously entered into by the Parent and the Company), (ii), in the
case of a Qualified Acquisition Proposal only, enter into, participate in,
conduct or




                                      -36-
<PAGE>   43

engage in discussions or negotiations with such Third Party, (iii) to the extent
that the Board of Directors of the Company is required by its fiduciary duties,
as advised by counsel, take any position with respect to an Acquisition Proposal
in accordance with Rules 14a-9 and 14e-2 promulgated under the Exchange Act, and
(iv) may, in the case of a Qualified Acquisition Proposal only and only prior to
the acceptance for payment of that number of Shares tendered pursuant to the
Offer sufficient to satisfy the Minimum Condition and in compliance with the
provisions of this Section 6.5 (including Section 6.5(c)), enter into an
agreement to consummate a Qualified Acquisition Proposal. For purposes of this
Agreement, "Acquisition Proposal" means an inquiry, offer or proposal regarding
any of the following (other than the transactions contemplated by this
Agreement) involving the Company or its Subsidiaries: (i) any merger,
reorganization, consolidation, share exchange, recapitalization, business
combination, liquidation, dissolution, or other similar transaction involving,
or, any sale, lease, exchange, mortgage, pledge, transfer or other disposition
of, all or any significant portion of the assets or 25% or more of the equity
securities of, the Company or any of its Subsidiaries, in a single transaction
or series of related transactions; (ii) any tender offer or exchange offer for
25% or more of the outstanding shares of capital stock of the Company or the
filing of a registration statement under the Securities Act in connection
therewith; or (iii) any public announcement of a proposal, plan or intention to
do any of the foregoing or any agreement to engage in any of the foregoing. For
purposes of this Agreement, "Qualified Acquisition Proposal" means an
unsolicited, bona fide, written Acquisition Proposal made by a Third Party that
the Board of Directors of the Company determines in its good faith judgment to
be more favorable to the Company's stockholders than the Offer and the Merger
(based on the opinion, with only customary qualifications, of the Company's
independent financial advisor that the value of the consideration to the
Company's stockholders provided for in such proposal exceeds the value of the
consideration to the Company's stockholders provided for in this Agreement by
the Offer and the Merger) and for which financing, to the extent required, is
then committed or which, in the good faith judgment of the Board of Directors of
the Company (based on the advice of the Company's independent financial
advisor), is reasonably capable of being obtained by such Third Party and which
Acquisition Proposal, in the good faith judgment of the Board of Directors of
the Company, is likely to be consummated. Nothing contained herein shall be
construed to prohibit the Company from making such disclosure to stockholders
that, in the judgment of the Board of Directors of the Company, as advised by
counsel, may be required by law or necessary to discharge any fiduciary duty
imposed thereby.

                  (b)      The Company will immediately notify the Parent of,
and will disclose to the Parent all details of, (i) any Acquisition Proposal it
receives, (ii) any written indications that any person is interested in making
an Acquisition Proposal or (iii) the initiation and status of discussions or
negotiations relating to any Acquisition Proposal (it being understood that
pursuant to Section 6.3, any such Acquisition Proposal must be a Qualified
Acquisition Proposal). In the event that the Company furnishes any nonpublic
information to any party other than the Parent, it shall simultaneously provide
the Parent with copies of or access to all such information. Nothing in this
paragraph (b) shall be construed as interfering with the 




                                      -37-
<PAGE>   44

Company's obligations to its stockholders under Rule 14e-2 promulgated under the
Exchange Act.

                  (c)      Notwithstanding any other provision in this
Agreement, the Company may not enter into any agreement with any Third Party in
connection with a Qualified Acquisition Proposal unless (i) at least three
business day prior thereto the Company shall have provided the Parent and the
Purchaser a copy of the Qualified Acquisition Proposal, (ii) within such three
business day period, the Parent and the Purchaser do not make an offer which, in
the good faith judgment of the Board of Directors of the Company (based on the
advice of the Company's independent financial advisor) is at least as favorable
to the Company's stockholders as such Acquisition Proposal, (iii) the Company
shall have terminated this Agreement pursuant to Section 8.1(b)(v) below, and
(iv) prior thereto the Company shall have paid the fees specified in Section
6.3(b) and shall have deposited $500,000 in trust with a Qualified Commercial
Bank for the payment of the expenses specified in Section 6.3(c).

                  (d)      The Company will use reasonable efforts to have all
copies of all nonpublic information it or its officers, directors, employees,
representatives or affiliates have distributed on or prior to the date of this
Agreement to other potential purchasers returned to the Company as soon as
possible.

         6.6      NOTIFICATION OF CERTAIN MATTERS.

                  (a)      The Company shall give prompt notice to the Parent,
of (i) any representation or warranty made by the Company contained in this
Agreement that is qualified as to materiality becoming untrue or inaccurate in
any respect or any such representation or warranty that is not so qualified
becoming untrue or inaccurate in any material respect, or (ii) the failure by
the Company to comply with or satisfy in any material respect any covenant,
condition or agreement to be complied with or satisfied by it under this
Agreement; provided, however, that no such notification shall be deemed to cure
any breach or otherwise affect the representations or warranties of the Company
or the conditions to the obligations of the parties hereunder.

                  (b)      Without limiting the foregoing, the Company shall,
within 24 hours after it has notice of any of the following, notify the Parent
of:

                           (i)      any notice or other communication from any
                  person alleging that the consent of such person is or may be
                  required in connection with the transactions contemplated by
                  this Agreement;

                           (ii)     any notice or other communication from any
                  Governmental Entity in connection with the transactions
                  contemplated by this Agreement; and




                                      -38-
<PAGE>   45

                           (iii)    any actions, suits, claims, investigations
                  or proceedings commenced or, to the best of its knowledge,
                  threatened against, relating to or involving or otherwise
                  affecting the Company or any Subsidiary which, if pending on
                  the date of this Agreement would have been required to have
                  been disclosed pursuant to this Agreement or which relate to
                  the consummation of the transaction contemplated hereby.

                  (c)      The Parent shall give prompt notice to the Company of
(i) any representation or warranty made by the Parent or the Purchaser contained
in this Agreement that is qualified as to materiality becoming untrue or
inaccurate in any respect or any such representation or warranty that is not so
qualified becoming untrue or inaccurate in any material respect, or (ii) the
failure by the Parent or the Purchaser to comply with or satisfy in any material
respect any covenant, condition or agreement to be complied with or satisfied by
them under this Agreement; provided, however, that no such notification shall be
deemed to cure any breach or otherwise affect the representations or warranties
of the Parent or the Purchaser or the conditions to the obligations of the
parties hereunder.

         6.7      ACCESS TO INFORMATION. Except as restricted under applicable
law and the restrictions noted below, the Company shall, and shall cause its
Subsidiaries, and the Company's and such Subsidiaries' respective officers,
directors, employees and agents to, afford to the Parent and to the officers,
employees, representatives and agents of the Parent (including attorneys,
accountants and environmental consultants) reasonable access at reasonable
times, from the date hereof to the Effective Time, to the Company's and any
Subsidiary's officers, employees, agents, facilities, properties, books, records
and contracts, and shall furnish the Parent all relevant financial, operating
and other data and information as the Parent, through its officers, employees or
agents, may reasonably request, except for information (other than information
subject to disclosure to the Parent or the Purchaser pursuant to Section 6.5)
received or held by the Company pursuant to a confidentiality agreement with a
third party which confidentiality agreement would be breached by such
disclosure. Without limiting the generality of the foregoing, the parties
expressly agree that such access will include full cooperation with the Parent
in connection with any environmental investigation to be undertaken by the
Parent. All such investigations and access shall be conducted in a manner as not
to interfere unreasonably with the business operations of the Company. All
access to personnel and facilities of the Company or any Subsidiary prior to the
closing of the Offer shall be made only with the prior written consent of the
Chairman of the Board or the Chief Financial Officer, which consent shall not be
unreasonably withheld or delayed. In addition, the Company agrees to cooperate,
as reasonably requested, in connection with filings by the Parent or the
Purchaser (or any affiliate of the Parent or the Purchaser) with the Commission
(including registration statements), including, without limitation, obtaining
financial information and related accountants' consents for inclusion in the
Parent's or the Purchaser's (or any of their affiliates') Commission filings.
Without limiting the generality of the foregoing, the Company shall use its best
efforts to secure for the Company access to and copies of the workpapers of its
independent public accountants.

         6.8      INDEMNIFICATION AND INSURANCE.

                  (a)      The Parent and the Purchaser agree that all rights to
indemnification, advancement of expenses, exculpation, limitation of liability
and any and all similar rights now existing in favor of the present or former
employees, agents, directors or officers of the Company and its Subsidiaries
(the "Indemnified Parties"), as provided in their respective charters or by-laws
in effect on the date hereof, shall survive the Offer and the Merger and shall
continue in full force and effect for a period of six years from the Effective
Time and shall not be amended, repealed or otherwise modified for a period of
six years from the Effective Time in any manner that would affect adversely the
rights thereunder of individuals who at any time prior to the Effective Time
were directors, officers, employees or agents of the Company, unless such
modification shall be required by law; PROVIDED, HOWEVER, that in the event any
claim or claims are asserted or made within such six-year period, all rights to
indemnification in respect to any such claim or claims shall continue until the
disposition of any and all such claims.

                  (b)      Subject to the terms and conditions of this Section
6.8, the Company shall, to the fullest extent permitted under applicable law and
regardless of whether the Merger becomes effective, indemnify and hold harmless,
and, after the Effective Time, the Surviving Corporation shall, to the fullest
extent permitted under applicable law, indemnify and hold harmless, each present
and former director, officer, employee, fiduciary and agent of the Company and
each Subsidiary and their respective heirs, executors, administrators, personal
representatives or assigns (collectively, the "Indemnified Parties") against all
costs and expenses (including attorneys' fees), judgments, fines, losses,
claims, damages, liabilities and settlement amounts paid in connection with any
claim, action, suit, proceeding or investigation (whether arising before or
after the Effective Time), whether civil, criminal, administrative or
investigative (a "Proceeding"), arising out of or pertaining to any action or
omission in their capacity as an officer, director, employee, fiduciary or
agent, whether occurring before or after the Effective Time, to the same extent
as provided in the Company's Certificate of Incorporation or By-laws as in
effect on the date hereof, in each case for a period of six years after the date
hereof. In the event that any claim for indemnification is asserted or made
within such six-year period, all rights to indemnification in respect of such
claim shall continue until the disposition of such claim.

                  (c)      Each Indemnified Party shall give written notice to
the Company or the Surviving Corporation, as the case may be (the "Indemnifying
Party") promptly after such Indemnified Party has actual knowledge of any claim
as to which indemnity may be sought, and shall permit the Indemnifying Party to
assume the defense of any Proceeding resulting therefrom; provided, that counsel
for the Indemnifying Party, who shall conduct the defense of such Proceeding,
shall be approved by the Indemnified Party (whose approval shall not be
unreasonably withheld, conditioned or delayed); and, provided, further, that the
failure of any Indemnified Party to given notice as provided herein shall not
relieve the Indemnifying Party of its obligations under Section 6.8(b) unless
and to the extent that the Indemnifying Party is adversely affected by such
failure. The Indemnified Party may participate in such defense at 




                                      -40-
<PAGE>   47

such party's expense; provided, however, that the Indemnifying Party shall pay
such expense if representation of such Indemnified Party by the counsel retained
by the Indemnifying Party would be inappropriate due to actual or potential
differing interests between the Indemnified Party and any other party
represented by such counsel in such proceeding. In the event that the
Indemnifying Party does not assume the defense pursuant to this paragraph (c) of
any Proceeding of which the Indemnifying Party receives notice as provided
herein, any expenses incurred by the Indemnified Party in defending such
Proceeding shall be paid by the Indemnifying Party in advance of the final
disposition of such matter, provided, however, that the payment of such expenses
incurred by the Indemnified Party in advance of the final disposition of such
matter shall be made only upon receipt of an undertaking by or on behalf of the
Indemnified Party to repay all amounts so advanced in the event that it shall
ultimately be determined that the Indemnified Party is not entitled to be
indemnified by the Indemnifying Party in accordance with this Section 6.8. The
Indemnified Party shall cooperate with the Indemnifying Party and provide access
to all documents necessary or beneficial to the defense of any Proceeding.
Neither the Company nor the Surviving Corporation shall be liable for any
settlement of any Proceeding effected without its written consent.

                  (d)      In the event the Company or the Surviving Corporation
or any of their respective successors or assigns consolidates with or merges
into any other person and shall not be the continuing or surviving corporation
or entity of such consolidation or merger, then, and in each such case, the
Parent will either guaranty the indemnification obligations referred to in this
Section 6.8 or will make or cause to be made proper provision so that the
successors and assigns of the Company or the Surviving Corporation, as the case
may be, assume the indemnification obligations described herein for the benefit
of the Indemnified Parties.

                  (e)      The provisions of this Section 6.8 are (i) intended
to be for the benefit of, and will be enforceable by, each of the Indemnified
Parties and (ii) in addition to, and not in substitution for, any other rights
to indemnification or contribution that any such person may have by contract or
otherwise.

                  (f)      The Parent shall maintain in effect for three years
from the date of the Effective Time, if available, directors' and officers'
liability insurance policies covering the directors and officers of the Company
as of the date hereof, with coverages and other terms substantially as favorable
to such directors and officers as is currently in effect; PROVIDED, HOWEVER,
that the Parent shall not be required to spend more than an amount per year
equal to 150% of the current annual premium paid by the Company as of the date
hereof for such insurance; and provided, further, that if the premium for such
coverage exceeds such amount, the Parent shall purchase a policy with the
greatest coverage available for such 150% of the annual premium.

         6.9      FILINGS AND OTHER MATTERS. The Company shall confer with the
Parent on a regular and frequent basis as reasonably requested by the Parent
concerning operational



                                      -41-
<PAGE>   48
matters and promptly advise the Parent orally and in writing of any change or
event having, or which, insofar as reasonably can be foreseen, could have, a
Material Adverse Effect. The Company shall promptly provide to the Parent (or
its counsel) copies of all filings made by the Company with any Governmental
Entity in connection with this Agreement and the transactions contemplated
hereby.

         6.10     FAIR PRICE STRUCTURE. If any "fair price" or "control share
acquisition" or "anti-takeover" statute, or other similar statute or regulation
or any state "blue sky" statute shall become applicable to the transactions
contemplated hereby or by the Stockholders' Agreement, the Company and the
members or the Board of Directors of the Company shall grant such approvals and
take such actions as are necessary so that the transactions contemplated hereby
and thereby may be consummated as promptly as practicable on the terms
contemplated hereby and thereby, and otherwise act to minimize the effects of
such statute or regulation on the transactions contemplated hereby or thereby.

         6.11     PARENT GUARANTY. The Parent hereby unconditionally and
irrevocably guarantees the Purchaser's obligations under this Agreement and
agrees to be liable for any breach of this Agreement by the Purchaser. The
guaranty described in this Section 6.11 is a guaranty of payment and not of
collection.

         6.12     COMPANY OPTIONS.

                  (a)      As of the Effective Time, the Parent shall assume the
Option Plan and the obligations of the Company thereunder and all of the Company
Options which are then outstanding shall be assumed by the Parent. Immediately
after the Effective Time, each such Company Option shall be deemed to constitute
an option to acquire, on the same terms and conditions as were applicable under
such Company Option immediately prior to the Effective Time, such number of
shares of common stock, par value $1.00 per share, of the Parent (the "Parent
Common Stock") as is equal to the number of Shares subject to such Company
Option immediately prior to the Effective Time multiplied by a fraction, the
numerator of which is the Merger Consideration and the denominator of which is
the average closing price of the Parent Common Stock on the New York Stock
Exchange, as reported in The Wall Street Journal (or if not so reported in
another authoritative source), for the ten trading days ending on the date of
the expiration of the Offer (with any fraction resulting from such
multiplication to be rounded down to the nearest whole number). The exercise
price per share of each such assumed Company Option shall be equal to the per
share exercise price of such Company Option immediately prior to the Effective
Time multiplied by a fraction, the numerator of which is the average closing
price of the Parent Common Stock on the New York Stock Exchange, as reported in
The Wall Street Journal (or if not so reported in another authoritative source),
for the ten trading days ending on the date of the expiration of the Offer and
the denominator of which is the Merger Consideration (with any fraction
resulting from such multiplication to be rounded up to the nearest whole cent).
Except as otherwise provided in this Section 6.12, the term, exercisability,
vesting schedule, status as an "incentive stock option" under Section 422 of the
Code and all of the other terms of the Company 




                                      -42-
<PAGE>   49
Options shall otherwise remain unchanged. This Section 6.12 is intended to meet
the requirements of Section 424(a) of the Code and shall be interpreted
consistent with such intent.

                  (b)      As soon as practicable after the Effective Time, the
Parent shall deliver to each holder of an outstanding Company Option an
appropriate notice setting forth such holder's rights pursuant to such Company
Options, as amended by this Section 6.12, and the agreements evidencing such
Company Options shall continue in effect on the same terms and conditions
(subject to the amendments provided for in this Section 6.12 and such notice).

                  (c)      The Parent shall take all corporate action necessary
to reserve for issuance a sufficient number of shares of Parent Common Stock for
delivery upon exercise of the Company Options assumed in accordance with this
Section 6.12. As soon as practicable after the Effective Time, the Parent shall,
with respect to all shares of Parent Common Stock subject to such Options, (i)
either (x) file a Registration Statement on Form S-8 (or any successor form)
under the Securities Act or (y) file any necessary amendments to the Company's
previously filed Registration Statements on Form S-8 in order that the Parent
will be deemed a "successor registrant" thereunder, and, in either event, shall
use all reasonable efforts to maintain the effectiveness of such registration
statement for so long as such Company Options remain outstanding, and (ii) take
all actions necessary to have such shares of Parent Common Stock approved for
listing on the New York Stock Exchange, subject to official notice of issuance.
Notwithstanding any other term of this Agreement, after the Effective Time, no
assumed Company Option may be exercised until such registration statement has
become effective and such approval has been obtained.

                  (d)      The Company shall take all necessary actions pursuant
to the Option Plan and the agreements evidencing the Company Options to provide
for the assumption of the Company Options in accordance with this Section 6.12.

         6.13     CERTAIN PAYMENTS. The Parent shall cause the Company to pay,
in accordance with their respective terms, all bonuses, severance payments,
accrued vacation pay and all other payments expressly set forth in Section 6.13
of the Disclosure Schedule to the persons set forth on such Disclosure Schedule
who will be terminated as of the closing of the Offer, within one business day
following payment and acceptance of the Shares in the Offer (except as otherwise
specifically set forth in Section 6.13 of the Disclosure Schedule, which shall
be paid in accordance therewith). The Company hereby represents and warrants
that, upon receipt of the payments listed in Section 6.13 of the Disclosure
Schedule, neither the Company nor any Subsidiary will have any further
obligation to any of the individuals listed in Section 6.13 other than (a)
pursuant to Company Options held by such individuals as set forth in Section 4.3
of the Disclosure Schedule or (b) as otherwise expressly provided for or
disclosed in this Agreement or the Disclosure Schedule.

         7.1      CONDITIONS TO OBLIGATION OF EACH PARTY TO EFFECT THE MERGER.
The respective obligations of each party to effect the Merger shall be subject
to the fulfillment or waiver by all parties at or prior to the Effective Time of
each of the following conditions:

                  (a)      The Parent or the Purchaser shall have made, or
caused to be made, the Offer on the terms and conditions set forth therein and
shall have purchased, or caused to be purchased, all Shares validly tendered and
not withdrawn pursuant to the Offer;

                  (b)      this Agreement and the Merger shall have been
approved and adopted by the requisite vote or consent of the stockholders of the
Company, if any, required by the Delaware Law and the Company's Certificate of
Incorporation;

                  (c)      any waiting period (and any extension thereof)
applicable to the consummation of the Merger under the Hart-Scott-Rodino Act
shall have expired or been terminated; and

                  (d)      no preliminary or permanent injunction or other
order, decree or ruling issued by a court of competent jurisdiction or by any
Governmental Entity, nor any statute, rule, regulation or executive order
promulgated or enacted by any Governmental Entity, shall be in effect, which
would make the acquisition or holding by the Parent or its subsidiaries of the
Shares or shares of common stock of the Surviving Corporation illegal or
otherwise prevent the consummation of the Merger.

         7.2      CONDITIONS TO THE PARENT'S AND THE PURCHASER'S OBLIGATION TO
EFFECT THE MERGER. The obligation of the Parent and the Purchaser to consummate
the Merger shall be further subject to the condition that, at or prior to the
Effective Time, all governmental and third-party consents and approvals required
to be obtained by the Company to consummate the Merger shall have been obtained,
except for (a) consents required under the Company's credit facility with
NationsBank, National Association as in effect on the date of this Agreement and
(b) such consents and approvals where the failure to obtain such consent or
approval would not have a Material Adverse Effect.

                        TERMINATION, AMENDMENT AND WAIVER

         8.1      TERMINATION. This Agreement may be terminated at any time
prior to the Effective Time, whether prior to or after approval by the
stockholders of the Company, as follows:




                                      -44-
<PAGE>   51

                  (a)      Subject to Section 1.3, by mutual written consent of
the Boards of Directors of the Parent and the Company; or

                  (b)      By the Company:

                           (i)      if neither the Parent nor any of its
                  subsidiaries or affiliates shall have (A) publicly announced
                  its intention to make the Offer no later than the first
                  business day following the date of this Agreement or (B)
                  commenced the Offer within five business days of such
                  announcement unless such failure to commence the Offer is due
                  to the material breach of this Agreement by the Company; or

                           (ii)     if, in the absence of any material breach of
                  this Agreement by the Company, (A) the Offer shall have been
                  terminated or the Purchaser shall have allowed the Offer to
                  expire without the purchase of such number of Shares
                  thereunder as satisfies the Minimum Condition (as defined in
                  ANNEX I hereto); or (B) neither the Parent nor any of its
                  subsidiaries or affiliates shall have paid for all Shares
                  validly tendered pursuant to the Offer and not withdrawn
                  within 60 days after the commencement of the Offer; or

                           (iii)    if the Effective Time shall not have
                  occurred on or before March 31, 1999 due to a failure of any
                  of the conditions to the obligation of the Company to effect
                  the Merger set forth in Section 7.1; or

                           (iv)     if, prior to the purchase of any Shares
                  pursuant to the Offer, the Parent or the Purchaser fails to
                  perform any of their respective obligations under this
                  Agreement and such failure or nonperformance materially
                  impairs the Parent's and the Purchaser's ability to consummate
                  the Offer or the Merger; or

                           (v)      if the Company has, in accordance with the
                  terms of Section 6.5 above, entered into an agreement with a
                  Third Party to consummate a Qualified Acquisition Proposal; or

                           (vi)     if there shall have been a breach of any
                  material representation and warranty of the Purchaser or the
                  Parent set forth herein prior to expiration or termination of
                  the Offer, which breach is not cured within five days
                  following written notice thereof by the Company to the
                  Purchaser and the Parent.

                  (c)      By the Parent:

                           (i)      if, due to an occurrence that would result
                  in a failure to satisfy any of the conditions set forth in
                  ANNEX I hereto, the Parent or any of its




                                      -45-
<PAGE>   52

                  subsidiaries or affiliates shall have (A) failed to commence
                  the Offer within five business days of the date on which the
                  Purchaser's intention to make the Offer is publicly announced;
                  (B) terminated the Offer without the purchase of any Shares
                  thereunder; or (C) failed to pay for Shares pursuant to the
                  Offer within 60 days after the commencement of the Offer; or

                           (ii)     if the Effective Time shall not have
                  occurred on or before March 31, 1999 due to a failure of any
                  of the conditions to the obligations of the Parent and the
                  Purchaser to effect the Merger set forth in Sections 7.1 and
                  7.2 otherwise than as a result of a material breach or default
                  by the Parent or the Purchaser hereunder; or

                           (iii)    if a Trigger Event specified in Section
                  6.3(e)(i) occurs; or

                           (iv)     if, prior to the purchase of any Shares
                  pursuant to the Offer, the Company fails to perform in any
                  respect any of its material obligations under this Agreement,
                  which failure to perform (other than a failure to perform an
                  obligation set forth in Section 6.5, as to which there shall
                  be no cure period) is not cured within five days following
                  written notice thereof by the Parent to the Company.

                  (d)      By either the Company or the Parent, if any
Governmental Entity shall have issued an order, decree or ruling or taken any
other action permanently enjoining, restraining or otherwise prohibiting the
acceptance for payment of, or payment for, Shares pursuant to the Offer or the
Merger and such order, decree or ruling or other action shall have become final
and nonappealable; provided, however, that the party seeking to terminate this
Agreement pursuant to this provision shall have performed its obligations under
Section 6.4.

                  (e)      Notwithstanding any other provision of this
Agreement, the termination of this Agreement by the Company pursuant to Section
8.1(b)(v) above shall be of no force or effect unless prior thereto the Company
shall have complied with Section 6.5(c) above.

         8.2      EFFECT OF TERMINATION. In the event of the termination of this
Agreement as provided in Section 8.1, all obligations and agreements of the
parties set forth in this Agreement shall forthwith terminate and be of no
further force or effect, and there shall be no liability on the part of the
Parent, the Purchaser or the Company hereunder, except as set forth in Section
6.3 or Section 9.4; provided that the foregoing shall not relieve any party for
liability for damages actually incurred as a result of any breach of this
Agreement.

         8.3      AMENDMENT. This Agreement may not be amended except, subject
to Section 1.3, by action of the Board of Directors of each of the parties
hereto set forth in an instrument in writing signed on behalf of each of the
parties hereto; provided, however, that if this Agreement and the Merger are
subject to stockholder approval then, after such approval,




                                      -46-
<PAGE>   53


no amendment shall be made which by law requires further approval by such
stockholders without obtaining such further approval.

         8.4      WAIVER. At any time prior to the Effective Time, whether
before or after any special meeting of the stockholders of the Company to vote
on the Merger, any party hereto, subject to Section 1.3, by action taken by its
Board of Directors, may (i) extend the time for the performance of any of the
obligations or other acts of any other party hereto or (ii) waive compliance
with any of the agreements of any other party or with any conditions to its own
obligations; provided, however, that if this Agreement and the Merger are
subject to stockholder approval then, after such approval, no waiver shall be
made which by law requires further approval by such stockholders without
obtaining such further approval. Any agreement on the part of a party hereto to
any such extension or waiver shall be valid only if set forth in an instrument
in writing signed on behalf of such party by a duly authorized officer. For
purposes of this Section 8.4, the Parent and the Purchaser shall be considered
to be one party.

                                    ARTICLE 9
                               GENERAL PROVISIONS

         9.1      PUBLICITY. The Parent and the Purchaser, on the one hand, and

         9.3      INTERPRETATION. When a reference is made in this Agreement to

this Agreement unless otherwise indicated. The table of contents and headings
contained in this Agreement are for reference purposes only and shall not affect
in any way the meaning or interpretation of this




                                      -48-
<PAGE>   55

Agreement. Whenever the words "include", "includes" or "including" are used in
this Agreement, including ANNEX I, they shall be deemed to be followed by the
words "without limitation". As used in this Agreement, including ANNEX I, the
term "subsidiary" of any person means another person whether foreign or
domestic, an amount of the voting securities, other voting ownership or voting
partnership interests of which is sufficient to elect at least a majority of its
Board of Directors or other governing body (or, if there are no such voting
interests, 50% or more of the equity interests of which) is owned directly or
indirectly by such first person. For avoidance of doubt, the parties acknowledge
that Voltarc Technologies, Inc. is a Subsidiary of the Company. As used in this
Agreement, including ANNEX I, the term "affiliate" of any person means any
person that directly or indirectly, through one or more intermediaries,
controls, is controlled by, or is under common control with, such first person.
For purposes of this Agreement, the Company shall not be deemed to be an
affiliate or subsidiary of the Purchaser or the Parent. Inclusion of information
in the Disclosure Schedule does not constitute an admission or acknowledgment of
the materiality of such information. For purposes of this Agreement, "business
day" shall have the meaning set forth in Rule 14d-1(c)(6) of the Exchange Act.

         9.4      REPRESENTATIONS AND WARRANTIES; ETC. The respective
representations and warranties of the Company, the Parent and the Purchaser
contained herein shall expire with, and be terminated and extinguished upon, the
Effective Time. This Section 9.4 shall have no effect upon any other obligation
of the parties hereto, which by their terms contemplate performance after the
Effective Time. If this Agreement shall terminate after acceptance for payment
by the Purchaser of Shares pursuant to the Offer, but prior to the Effective
Time, the agreements of the parties contained in Sections 6.3, 6.8, 6.11 and
6.13 shall also survive the termination of this Agreement.

         9.5      MISCELLANEOUS. This Agreement together with the
Confidentiality Agreement between the Parent and the Company dated June 9, 1998
constitutes the entire agreement and supersedes all other prior agreements and
undertakings, both written and oral, among the parties, or any of them, with
respect to the subject matter hereof. This Agreement (i) except as provided in
Sections 6.8, 6.11 and 6.13 is not intended to confer upon any other person any
rights or remedies hereunder, create any agreement of employment with any person
or otherwise create any third-party beneficiary hereto; (ii) shall not be
assigned, except that the Purchaser may assign its rights and obligations to one
or more direct or indirect wholly owned subsidiaries of the Parent which in a
written instrument shall make all the representations and warranties of the
Purchaser set forth herein and shall agree to assume all of the Purchaser's
obligations hereunder and be bound by all of the terms and conditions of this
Agreement; provided, however, that no such assignment shall relieve the Parent
or the Purchaser of its obligations hereunder; and (iii) shall be governed in
all respects, including validity, interpretation and effect, by the internal
laws of the State of Delaware, without giving effect to the principles of
conflict of laws thereof.

         9.6      VALIDITY. The invalidity or unenforceability of any provision
of this Agreement shall not affect the validity or enforceability of any other
provisions of this Agreement, which shall remain in full force and effect.

         9.7      COUNTERPARTS. This Agreement may be executed in two or more
counterparts, all of which shall be considered one and the same agreement and
shall become effective when two or more counterparts have been signed by each of
the parties and delivered to the other parties, it being understood that all
parties need not sign the same counterpart.

         9.8      SEVERABILITY. If any term or other provision of this Agreement
is invalid, illegal or incapable of being enforced by any rule of law, or public
policy, all other conditions and provisions of this Agreement shall nevertheless
remain in full force and effect so long as the economic and legal substance of
the transactions contemplated hereby are not affected in any manner materially
adverse to any party. Upon such determination that any term or other provision
is invalid, illegal or incapable of being enforced, the parties shall negotiate
in good faith to modify this Agreement so as to effect the original intent of
the parties as closely as possible in a mutually acceptable manner in order that
the transactions contemplated by this Agreement may be consummated as originally
contemplated to the fullest extent possible.

"Parent"), Lighthouse Weston Corp., a Delaware corporation and a wholly owned
subsidiary of the Parent (the "Purchaser"), and the holders (the "Stockholders")
of the shares of Common Stock, $0.01 par value (the "Shares"), of Lumen
Technologies, Inc., a Delaware corporation (the "Company"), listed on SCHEDULE A
hereto.

         WHEREAS, concurrently herewith, the Parent, the Purchaser and the
Company are entering into an Agreement and Plan of Merger (as it may be amended
from time to time in the future in accordance with its terms, the "Merger
Agreement"), pursuant to which the Purchaser agrees to make a tender offer (the
"Offer") for all of the Shares at $7.75 per share, net to the seller in cash, to
be followed by the merger of the Purchaser with and into the Company (the
"Merger"), with the Company being the entity surviving the Merger and becoming a
wholly owned subsidiary of the Parent; and

         WHEREAS, in order to induce the Parent and the Purchaser to enter into
the Merger Agreement, the Parent and the Purchaser have requested the
Stockholders, and the Stockholders have agreed, to enter into this Agreement;

         NOW, THEREFORE, the parties hereto agree as follows:


                                    ARTICLE I

                               AGREEMENT TO TENDER

         Section 1.1   TENDER OF SHARES. Each Stockholder hereby agrees to 
validly tender, and not to withdraw, pursuant to and in accordance with the
terms of the Offer, (i) within five business days after the commencement of the
Offer, all Shares owned by such Stockholder as of the execution and delivery of
this Agreement (as indicated on SCHEDULE A hereto) and, (ii) prior to the
scheduled expiration of the Offer, any additional Shares hereafter acquired by
such Stockholder (whether by purchase, exercise of options or otherwise).

         Section 1.2   PROCEDURE FOR TENDERING. Within the time periods 
specified in Section 1.1, the Stockholder shall deliver to the depositary
designated in the Offer (i) a duly completed and signed letter of transmittal

instruments required to be delivered pursuant to the terms of the Offer.





<PAGE>   2

         Section 1.3   PAYMENT OF OFFER PRICE. The parties agree that each
Stockholder will, for all Shares tendered in the Offer and accepted for payment
and paid for by the Purchaser, receive the same per share consideration paid to
other stockholders of the Company who have tendered Shares into the Offer.


                                   ARTICLE II

                  VOTING AGREEMENT; IRREVOCABLE GRANT OF PROXY

         Section 2.1   VOTING AGREEMENT. Each Stockholder hereby agrees to vote
all Shares that such Stockholder is entitled to vote at the time of any vote to
approve and adopt the Merger Agreement, the Merger and all agreements related to
the Merger and any actions related thereto at any meeting of the stockholders of
the Company, and at any adjournment thereof (or by written consent in lieu of a
meeting), at which such Merger Agreement and other related agreements (or any
amended version thereof), or such other actions, are submitted for the
consideration and vote of the stockholders of the Company. Each Stockholder
hereby agrees that it will not vote (or give a written consent with respect to)
any Shares in favor of the approval of any (i) Acquisition Proposal, (ii)
reorganization, recapitalization, liquidation or winding up of the Company or
any other extraordinary transaction involving the Company, (iii) corporate
action the consummation of which would frustrate the purposes, or prevent or
delay the consummation, of the transactions contemplated by the Merger
Agreement, or (iv) other matter relating to, or in connection with, any of the
foregoing matters.

         Section 2.2   IRREVOCABLE PROXY. Each Stockholder hereby revokes any 
and all previous proxies granted with respect to such Stockholder's Shares. Each
Stockholder hereby grants a proxy appointing the Purchaser as such Stockholder's
attorney-in-fact and proxy, with full power of substitution, for and in such
Stockholder's name, to vote, express consent or dissent, or otherwise to utilize
such voting power in such manner and upon such matters as the Purchaser or its
proxy or substitute shall, in the Purchaser's sole discretion, deem proper with
respect to such Stockholder's Shares. The proxy granted by each Stockholder
pursuant to this Section 2.2 is irrevocable and is granted in consideration of
the Purchaser's entering into this Agreement and the Merger Agreement and
incurring certain related fees and expenses. The proxy grant by each Stockholder
shall be revoked upon termination of this Agreement in accordance with its
terms. At the Purchaser's request, each Stockholder shall perform such further
acts and execute such further documents as may reasonably be required to vest in
the Purchaser the sole power to vote the Shares during the term of the proxy
granted herein.

Dear Mr. Castalana:

In connection with the consideration by Lumen (as defined below) and EGG (as 
defined below) of a possible transaction (the "Transaction") involving Lumen 
and EGG, Lumen and EGG will each provide the other with confidential 
information. In consideration of the mutual covenants contained in this 
agreement, each party agrees as follows:

     1.   Definitions

          (a)  "Confidential Information" means all information (whether
               written, oral or in any other form and whether prepared by the
               Disclosing Party, any of its representatives or otherwise), other
               than Exempt Information, which is provided by the Disclosing
               Party or any of its representatives to the Recipient or any of
               its representatives before the end of the Disclosure Period in
               connection with the Recipient's consideration of a possible
               Transaction. For purposes of this agreement, Confidential
               Information also includes all summaries, notes, studies,
               interpretations or other materials prepared by the Recipient or
               any of its Permitted Users (as defined below) that contain or are
               based upon, in whole or in part, any of the information referred
               to in the preceding sentence (the "Notes").

          (b)  "Disclosure Period" means the period beginning on the date
               hereof and ending on the first anniversary of the date of this
               letter, provided that the

<PAGE>   2
     Disclosure Period may be terminated earlier by mutual agreement of the 
     parties or upon the written request of either party.

(c)  "EXEMPT INFORMATION" means information which (i) the Recipient can prove or
     document it possessed on a non-confidential basis before the Disclosing
     Party disclosed it to the Recipient under this agreement and where the
     provider of such information to the Recipient was not known by the 
     Recipient to be subject to any confidentiality obligation to any person 
     with respect to such information, (ii) is or becomes generally available 
     to the public other than as a result of disclosure by the Recipient or any 
     of its Permitted Users in violation of this agreement; or (iii) the 
     Recipient obtains from a third party on a non-confidential basis (to the 
     Recipient's knowledge) that did not obtain the information directly or 
     indirectly from the Disclosing Party and was not known by the Recipient to 
     be subject to any confidentiality obligation to any person with respect to 
     such information.

(d)  "PERMITTED USE" means the evaluation of possible Transaction between Lumen 
     and EGG.

(e)  "PERMITTED USER" means an individual who (i) is a director, officer, 
     employee, agent, advisor or consultant of or to the Recipient or any of 
     its Affiliates; (ii) has agreed to be bound by the terms of this agreement 
     as if he or she were a "RECIPIENT" hereunder and a party hereto; and (iii) 
     has a need to know the Confidential Information in connection with the 
     Permitted Use. In addition, with respect to Confidential Information that 
     the Disclosing Party believes is unusually sensitive due to commercial, 
     legal or other factors, as a condition to the Disclosing Party's provision 
     of such information to the Recipient, the Disclosing Party and the 
     Recipient will mutually agree upon a limited number of specific 
     individuals to receive such information on behalf of the Recipient, and, 
     with respect to such information (and related Notes), only such specified 
     individuals shall be Permitted Users.

(f)  "EGG" means EG&G, Inc. and its Affiliates.

(g)  "LUMEN" means Lumen Technologies, Inc. and its Affiliates.

(h)  "AFFILIATES" means, with respect to each party, the legal entities that 
     control, are controlled by, or are under common control with such party.

(i)  "RECIPIENT" means the party to which (or to the representatives of which) 
     Confidential Information is disclosed by the other party.

(j)  "DISCLOSING PARTY" means the party which discloses (or on whose behalf 
     information is disclosed) Confidential Information to the other party.

2.     Treatment of Confidential Information

       (a)  The Recipient will treat Confidential Information as confidential
            and proprietary, and the Recipient will safeguard its confidential
            and proprietary nature with at least the same degree of care as the
            Recipient treats its own confidential or proprietary information. In
            addition, the Recipient will comply with the other provisions of
            this agreement and take or abstain from taking various actions as
            herein set forth.

       (b)  The Recipient and its Permitted Users may use, copy and make
            extracts of Confidential Information, or otherwise use, make and
            copy Notes, only in connection with the Permitted Use, and for no
            other purpose. Without limiting the generality of the foregoing, the
            Recipient and its Permitted Users shall not use Confidential
            Information to divert or attempt to divert any business of the
            Disclosing Party.

       (c)  The Recipient will not disclose Confidential Information to, or
            permit it to be accessed by, any person except Permitted Users who
            have a need to know it in connection with the Permitted Use. The
            Disclosing Party may waive the restrictions of this paragraph 2(c)
            on a case-by-case basis to provide for specific disclosures to
            specific third parties. The waiver must be in writing signed by an
            officer of the Disclosing Party. The Recipient will ensure that each
            of its Permitted Users complies fully with the provisions of this
            agreement.

       (d)  Neither party will disclose that discussions between the parties are
            taking place concerning a possible Transaction, or any aspect of, or
            any other matter relating to, such discussions, to any third party
            without the other's prior written consent; provided, that, after
            consultation with the other party (to the extent such consultation
            is reasonably practicable), each party may disclose such information
            to the extent required by law or by agreement with a national
            securities exchange, in the opinion of such party's legal counsel.

       (e)  At the end of the Disclosure Period, or earlier if the Disclosing
            Party so requests, the Recipient will (i) promptly return to the
            Disclosing Party all Confidential Information provided by or on
            behalf of the Disclosing Party to the Recipient (or any of its
            Permitted Users) and all Notes (including, without limitation, all
            Notes created or prepared by its Permitted Users) and, except as set
            forth in paragraph 2(f), the Recipient will destroy all copies of
            Confidential Information and all copies of all Notes then in the
            Recipient's possession or under the Recipient's control (including,
            without


                                       3
<PAGE>   4
          limitation, all copies and Notes provided to, or made by, any
          Permitted User) and (ii) provide the Disclosing Party with a written
          statement of an officer of the Recipient indication that the Recipient
          has complied with the requirements of this paragraph 2(e).

     (f)  Notwithstanding paragraph 2(e), the Recipient's outside counsel may
          retain a single copy of Confidential Information and Notes for the
          sole purpose of ascertaining the Recipient's ongoing rights and
          responsibilities respecting such information.

     (g)  In the event that the Recipient or any of its Permitted Users becomes
          legally compelled pursuant to judicial or administrative subpoena or
          process of other legal obligation to disclose any Confidential
          Information supplied to it or any of its Permitted Users or any Notes,
          the Recipient (or such Permitted User) shall provide the Disclosing
          Party with prompt notice of any such subpoena, process or obligation,
          so that the Disclosing Party may seek an appropriate protective order
          and/or waive the Recipient's compliance with the provisions of this
          agreement. If in the absence of a protective order or the receipt of a
          waiver hereunder, the Recipient or such Permitted User is nonetheless,
          in the opinion of its legal counsel, compelled to disclose any such
          Confidential Information or else stand liable for contempt or suffer
          other censure or penalty, notwithstanding any other provision of this
          agreement to the contrary, the Recipient or such Permitted User may
          disclose only that portion of the Confidential Information that, in
          the opinion of its legal counsel, it is legally required to disclose
          without liability hereunder.

3.   Other Matters

     (a)  Each party represents and warrants to the other that it has the legal
          power and authority to enter into and perform under this agreement and
          that such performance (including, without limitation, the delivery of
          Confidential Information hereunder) will not violate the rights, or
          require the consent, of any third party.

     (b)  Neither this agreement, nor either party's performance under it, nor
          any other written or oral agreement or expression with respect to a
          possible Transaction, will (i) transfer to the Recipient, or create in
          the Recipient, any proprietary right, title, interest or claim in or
          to any Confidential Information; (ii) obligate either party to enter
          into any other agreement or impose any legal obligation on Lumen or
          EGG with respect to any Transaction (it being understood that no such
          obligations will arise unless and until a definitive agreement with
          respect to a Transaction is approved by Lumen and EGG and executed and
          delivered by such parties); or (iii) prohibit either party from
          entering into any other agreement if the

                                       4




<PAGE>   5
     execution and performance of such agreement would not violate such party's
     obligations hereunder.

(c)  Subject to the earlier termination of obligations under this agreement, 
     the Recipient's obligations under this agreement shall terminate
     automatically on the third (3rd) anniversary of the date of this agreement.

(d)  This agreement sets forth the parties' entire understanding about its
     subject matter and supersedes any other agreement or understanding, whether
     verbal or in writing, between the parties about its subject matter. Neither
     party can assign, amend, waive or terminate any part of this agreement
     except by writing signed by both parties.

(e)  This agreement shall be governed by, and construed and enforced in
     accordance with, the law of the State of New York, excluding its conflict
     of law rules.

(f)  Lumen and EGG acknowledge that certain information may not be provided to
     the other party unless and until the parties are engaged in more definitive
     discussions concerning the Transaction, it being understood that, as set
     forth in paragraph 3(b), neither party is obligated to pursue any such
     discussions or Transaction. Each party acknowledges that, except as
     specifically proved herein, neither party has made any promise to the
     other, express or implied, upon which either is entitled to rely in any
     way, and, except as specifically provided herein, the parties specifically
     waive and disclaim any reliance, dependence or action based on any written
     or verbal statement or promise made by either party to the other. Without
     limiting the generality of the foregoing, it is understood that none of
     Lumen, EGG or any of their Permitted Users (i) has made any representation
     or warranty, express or implied, with respect to the accuracy or
     completeness of the Confidential Information or any statement, fact,
     estimate, projection, assumption or other information contained therein or
     (ii) will have any liability whatsoever to any other person relating to or
     resulting from the use of any Confidential Information or any errors
     therein or omissions therefrom.

(g)  Each of Lumen and EGG agrees that neither it nor any of its Affiliates will
     solicit to employ any officers or employees employed in any of the current
     business of the other party and its Affiliates with whom the soliciting
     party or any of its representatives has had contact or who were otherwise
     identified to the soliciting party or any of its representatives during the
     period of its evaluation of a possible Transaction for a period of two (2)
     years following any termination of this agreement, except through general
     solicitations (through employee search firms or otherwise) not targeted to
     officers or employees of the other party or its Affiliates, it being
     understood that responding to unsolicited indications of interest from such




                                       5
<PAGE>   6
          officers or employees will not be deemed solicitation for purposes of
          this paragraph 3(g).

     (h)  Each of Lumen and EGG acknowledge that they are aware of the
          securities laws of the United States relating to the use of material,
          non-public information.

     (i)  The parties agree that money damages would not be sufficient remedy
          for any breach of this agreement by either party, and that in addition
          to all other remedies each party shall be entitled to specific
          performance and injunctive or other equitable relief as a remedy for
          any such breach by the other. Each party further agrees to waive, and
          to use its best efforts to cause its Permitted Users to waive, any
          requirement for the securing or posting of any bond in connection
          with such remedy. In the event of litigation relating to this
          agreement, if a court of competent jurisdiction determines that either
          party or any of its Permitted Users has breached this agreement, the
          breaching party shall be liable and pay to the other party the
          reasonable legal fees incurred by the other party in connection with
          such litigation.

   If the foregoing terms are acceptable, please return the enclosed copy of 
this agreement signed by a duly authorized officer.

     Very truly yours,
