                              SUMMARY OF THE OFFER

Principal terms

 .  Danaher Corporation ("Danaher"), through its wholly-owned subsidiary
   Saltwater Acquisition Corp. (the "Purchaser"), is offering to buy all
   outstanding shares of Lifschultz Industries, Inc. ("Lifschultz") common
   stock for $22.80 per share, net to you in cash, upon the terms and subject
   to the conditions contained in this offer to purchase and in the related
   letter of transmittal. Tendering stockholders will not have to pay brokerage
   fees or commissions. Stockholders who hold their shares through a broker or
   bank should consult that institution as to whether it charges any service
   fees or commissions.

 .  The offer is the first step in our plan to acquire all of the outstanding
   Lifschultz shares, as provided in our merger agreement with Lifschultz. If
   the offer is successful, we will acquire any remaining shares of Lifschultz
   common stock for $22.80 per share in cash in a later merger. If we acquire
   at least 90% of the outstanding shares, we intend to cause the merger to
   become effective without a meeting of the stockholders of Lifschultz in
   accordance with Section 253 of the General Corporation Law of the State of
   Delaware. The stockholders of Lifschultz will have appraisal rights in the
   merger.

 .  Danaher has entered into a stockholders' agreement with David K. Lifschultz,
   Sidney B. Lifschultz, Lawrence Lifschultz, David A. Berman, the Sidney B.
   Lifschultz 1992 Family Trust, Michael Hirst and J. Randall Owen (each, a
   "Principal Stockholder"), whereby each Principal Stockholder has agreed to
   (1) tender or cause to be tendered in the offer all shares owned of record
   or beneficially by such Principal Stockholder, and (2) vote or cause to be
   voted all shares owned of record or beneficially by such Principal
   Stockholder in favor of the merger agreement and the merger and against any
   alternative acquisition proposal. Together, the Principal Stockholders, as
   of May 15, 2001, owned or had voting and investment control over 478,189
   shares, or approximately 42% of the outstanding shares.

 .  The initial offering period of the offer will expire at 12:00 midnight, New
   York City time, on Tuesday, June 19, 2001, unless we extend the offer.

 .  If we decide to extend the offer, we will issue a press release giving the
   new expiration date no later than 9:00 a.m., New York City time, on the
   first business day after the previously scheduled expiration date of the
   offer.

Lifschultz board recommendation

   The board of directors of Lifschultz unanimously:

  .  determined that the merger agreement and each of the transactions
     contemplated thereby, including each of the offer and the merger, are
     advisable, fair to and in the best interests of Lifschultz and its
     stockholders,

  .  approved the offer and the merger and adopted the merger agreement in
     accordance with the General Corporation Law of the State of Delaware,
     and

  .  recommends that the stockholders of Lifschultz accept the offer and
     tender their shares pursuant to the offer.

Conditions

   We are not required to complete the offer unless at least a majority of the
shares of common stock of Lifschultz outstanding on a fully diluted basis on
the date of purchase are validly tendered and not withdrawn prior to the
expiration of the offer. As used in this Offer to Purchase, "fully diluted
basis" means the number

                                       ii


of shares then outstanding, plus all shares issuable upon the conversion of any
then outstanding convertible securities or upon the exercise of any then
outstanding options, warrants or rights. Other conditions to the offer are
described at pages 24 through 26. The offer is not conditioned on Danaher
obtaining financing.

Procedures for tendering

   If you wish to accept the offer, this is what you must do:

  .  If you are a record holder (i.e., a stock certificate has been issued to
     you), you must complete and sign the enclosed letter of transmittal and
     send it with your stock certificate to the depositary for the offer or
     follow the procedures described in the offer for book-entry transfer.
     These materials must reach the depositary before the offer expires.
     Detailed instructions are contained in the letter of transmittal and on
     pages 5 through 8 of this document.

  .  If you are a record holder but your stock certificate is not available
     or you cannot deliver it to the depositary before the offer expires, you
     may be able to tender your shares using the enclosed notice of
     guaranteed delivery. Please call our information agent, D.F. King & Co.,
     Inc., toll-free at 800- 207-2872 for assistance. See pages 6 and 7 for
     further details.

  .  If you hold your shares through a broker or bank, you should contact
     your broker or bank and give instructions that your Lifschultz shares be
     tendered.

Withdrawal rights

 .  If, after tendering your shares in the offer, you decide that you do not
   want to accept the offer, you can withdraw your shares by so instructing the
   depositary in writing before the offer expires. If you tendered by giving
   instructions to a broker or bank, you must instruct the broker or bank to
   arrange for the withdrawal of your Lifschultz shares. See pages 8 and 9 for
   further details.

Subsequent offering period

 .  We may give stockholders who do not tender in the offer another opportunity
   to tender at the same price in a subsequent offering period. Although we do
   not currently intend to include a subsequent offering period, we reserve the
   right to do so.

 .  Any subsequent offering period will begin on the day we announce that we
   have purchased shares in the offer and last for at least three business
   days. We may extend the subsequent offering period, but it will not last
   more than 20 business days in total.

 .  There would be no withdrawal rights in any subsequent offering period.

Recent Lifschultz trading prices; subsequent trading

 .  The closing price for shares of Lifschultz common stock was:

  $19.00 per share on May 15, 2001, the last trading day before we announced
  the merger agreement with Lifschultz, and

  $22.63 per share on May 18, 2001, the last trading day before the printing
  of these materials.

Before deciding whether to tender, you should obtain a current market quotation
for the shares.

 .  If the offer is successful, we expect the shares of Lifschultz common stock
   to continue to be traded on the Nasdaq SmallCap Market until the time of the
   merger, although we expect trading volume to be below its pre-offer level.
   Following the merger, the shares will no longer trade on the Nasdaq SmallCap
   Market.

                                      iii

To:All Holders of Shares of
Common Stock of Lifschultz Industries, Inc.

                                  INTRODUCTION

   The Purchaser, an indirect, wholly-owned subsidiary of Danaher, is offering
to purchase all outstanding shares of common stock (the "Shares") of Lifschultz
at a purchase price of $22.80 per Share, net to the seller in cash, without
interest, on the terms and subject to the conditions set forth in this Offer to
Purchase and in the related Letter of Transmittal (which together constitute
the "Offer"). The "Offer" includes any subsequent offering period, as described
in Section 1.

   You will not be required to pay brokerage fees or commissions or, except as
described in Instruction 6 of the Letter of Transmittal, stock transfer taxes
on the purchase of Shares in the Offer. Stockholders who hold their Shares
through bankers or brokers should check with such institutions as to whether or
not they charge any service fee. However, if you do not complete and sign the
Substitute Form W-9 that is included in the Letter of Transmittal, you may be
subject to a required backup U.S. federal income tax withholding of 31% of the
gross proceeds payable to you. See Section 3. We will pay all charges and
expenses of SunTrust Bank, as Depositary (the "Depositary"), and D.F. King &
Co., Inc., as Information Agent (the "Information Agent"), incurred in
connection with the Offer. See Section 16.

   The board of directors of Lifschultz has unanimously determined that the
Merger Agreement (as defined herein) and each of the transactions contemplated
thereby, including each of the Offer and the Merger (as defined herein), are
advisable, fair to and in the best interests of Lifschultz and its
stockholders, approved the Offer and the Merger and adopted the Merger
Agreement in accordance with the General Corporation Law of the State of
Delaware, and recommends that the stockholders of Lifschultz accept the Offer
and tender their Shares pursuant to the Offer.

   We are not required to purchase any Shares unless at least a majority of the
Shares outstanding on a fully diluted basis on the date of purchase are validly
tendered and not withdrawn prior to the expiration of the Offer (the "Minimum
Condition"). We reserve the right (subject to the applicable rules and
regulations of the Securities and Exchange Commission (the "SEC") and to the
prior written consent of Lifschultz), which we presently have no intention of
exercising, to waive or reduce the Minimum Condition and to elect to purchase a
smaller number of Shares. The Offer is also subject to certain other terms and
conditions. See Sections 1, 14, and 15.

   We are making the Offer under the Agreement and Plan of Merger, dated as of
May 15, 2001, by and among Lifschultz, Danaher and the Purchaser (the "Merger
Agreement"). Following the consummation of the Offer and the satisfaction or
waiver of certain conditions, Lifschultz will merge with the Purchaser (the
"Merger"), with Lifschultz continuing as the surviving corporation. In the
Merger, each outstanding Share (other than (a) any Shares held by Danaher, the
Purchaser, any wholly-owned subsidiary of Danaher or the Purchaser, in the
treasury of Lifschultz or by any wholly-owned subsidiary of Lifschultz, which
Shares, by virtue of the Merger and without any action on the part of the
holder of those Shares, will be canceled and retired and will cease to exist
with no payment being made with respect thereto and (b) Shares held by a holder
who has not voted in favor of the Merger and who has demanded appraisal for
those Shares in accordance with the General Corporation Law of the State of
Delaware (the "GCL")) will be converted into the right to receive $22.80, net
in cash, or any higher price that may be paid in the Offer, without interest
(the "Merger Consideration"). Section 11 contains a more detailed description
of the Merger Agreement. Section 5 describes the principal U.S. federal income
tax consequences of the sale of Shares in the Offer and the Merger.

   Houlihan Valuation Advisors, Lifschultz's financial advisor ("Houlihan"),
has delivered to the board of directors of Lifschultz a written opinion that,
as of the date of the Merger Agreement and based on and subject to the
assumptions and limitations described in the opinion, the per Share
consideration to be paid in the Offer and the Merger is fair to the
disinterested stockholders of Lifschultz from a financial point of view. A copy
of


the opinion of Houlihan is included with Lifschultz's
Solicitation/Recommendation Statement on Schedule 14D-9, which is being mailed
with this document, and stockholders are urged to read the opinion in its
entirety for a description of the assumptions made, matters considered and
limitations of the review undertaken by Houlihan.

   Approval of the Merger requires the affirmative vote of holders of a
majority of the outstanding Shares. As a result, if the Minimum Condition and
the other conditions to the Offer are satisfied and the Offer is completed, we
will own a sufficient number of Shares to ensure that the Merger will be
approved by Lifschultz's stockholders. See Section 11.

   Lifschultz has advised us that, to its knowledge, all of its executive
officers and directors intend to tender all Shares that they own of record or
beneficially in the Offer (other than Shares that they have the right to
purchase by exercising stock options and Shares, if any, that if tendered would
cause them to incur liability under the short-swing profits provisions of the
Securities Exchange Act of 1934, as amended). Danaher has also entered into a
stockholders' agreement (the "Stockholders' Agreement") with David K.
Lifschultz, Sidney B. Lifschultz, Lawrence Lifschultz, David A. Berman, the
Sidney B. Lifschultz 1992 Family Trust, Michael Hirst and J. Randall Owen,
whereby each such Principal Stockholder has agreed to (1) tender or cause to be
tendered in the Offer all Shares owned of record or beneficially by such
Principal Stockholder, and (2) vote or cause to be voted all Shares owned of
record or beneficially by such Principal Stockholder in favor of the Merger
Agreement and the Merger and against any alternative acquisition proposal.
Together, the Principal Stockholders, as of May 15, 2001, owned or had voting
and investment control over 478,189 Shares, or approximately 42% of the
outstanding Shares.

   Lifschultz has informed us that, as of May 15, 2001, there were 1,128,476
Shares issued and outstanding, no shares of preferred stock outstanding and
160,884 Shares reserved for issuance upon the exercise of outstanding stock
options.

   The Offer is conditioned upon the fulfillment of the conditions described in
Section 14. The initial offering period of the Offer will expire at 12:00
midnight, New York City time, on Tuesday, June 19, 2001, unless we extend it.

   This Offer to Purchase and the related Letter of Transmittal contain
important information which you should read carefully before you make any
decision with respect to the Offer.

1. Terms of the Offer.

   Upon the terms and subject to the conditions of the Offer (including, if the
Offer is extended or amended, the terms and conditions of any extension or
amendment), we will purchase all Shares validly tendered and not withdrawn in
accordance with the procedures set forth in Section 3 on or prior to the
Expiration Date. "Expiration Date" means 12:00 midnight, New York City time, on
Tuesday, June 19, 2001, unless we, in our sole discretion, extend the period of
time for which the initial offering period of the Offer is open, in which case
"Expiration Date" will mean the time and date at which the initial offering
period of the Offer, as so extended, will expire.

   Subject to the terms of the Merger Agreement (see Section 11 of this Offer
to Purchase) and the applicable rules and regulations of the SEC, we expressly
reserve the right, in our sole discretion, at any time or from time to time, to
extend the Offer by giving oral or written notice of such extension to the
Depositary and by making a public announcement as described below. During any
such extension, all Shares previously tendered and not withdrawn will remain
subject to the Offer and subject to your right to withdraw Shares. See Section
4. Subject to the applicable regulations of the SEC and the terms of the Merger
Agreement, we also reserve the right, in our sole discretion, at any time or
from time to time, to (a) delay purchase of or, regardless of whether we
previously purchased any Shares, payment for any Shares pending receipt of any
regulatory or governmental approvals specified in Section 15; (b) terminate the
Offer (whether or not any Shares have previously been

                                       2


purchased) if any condition referred to in Section 14 has not been satisfied or
upon the occurrence of any Event specified (and defined) in Section 14; and (c)
except as set forth in the Merger Agreement, waive any condition or otherwise
amend the Offer in any respect, in each case, by giving oral or written notice
of the delay, termination, waiver or amendment to the Depositary and by making
a public announcement as described below. We acknowledge (a) that Rule 14e-1(c)
under the Securities Exchange Act requires us to pay the consideration offered
or return the Shares tendered promptly after the termination or withdrawal of
the Offer and (b) that we may not delay purchase of, or payment for (except as
provided in clause (a) of the preceding sentence), any Shares upon the
occurrence of any Event specified in Section 14 without extending the period of
time during which the Offer is open. The rights we reserve in this paragraph
are in addition to our rights pursuant to Section 14.

   Subject to the terms of the Merger Agreement, we have the right, in our sole
discretion, to modify and make changes to the terms and conditions of the
Offer, except that we have agreed that we will not, without the prior written
consent of Lifschultz:

  .  decrease the price per share to be paid pursuant to the Offer;

  .  change the form of consideration payable in the Offer;

  .  decrease the number of Shares sought to be purchased in the Offer;

  .  impose additional conditions to the Offer;

  .  waive the Minimum Condition; or

  .  amend any other term of the Offer in any manner adverse to the holders
     of Shares.

   However, the Merger Agreement also provides that, without the consent of
Lifschultz, we may (1) extend the Offer from time to time, if at the Expiration
Date any of the conditions to the Offer are not satisfied or have not been
waived by the Purchaser, (2) extend the Offer from time to time for up to a
maximum of ten additional business days in the aggregate for all such
extensions, if as of the Effective Time all of the conditions to the Offer are
satisfied but less than 90% of the outstanding Shares have been validly
tendered and not withdrawn in the Offer; and (3) provide a subsequent offering
period after the Expiration Date, in accordance with and subject to the
requirements of Rule 14d-11 under the Exchange Act. We have agreed that, upon
the terms and subject to the conditions to the Offer, we will accept for
payment and pay for, all Shares validly tendered and not withdrawn prior to the
expiration of the Offer as promptly as practicable after expiration of the
Offer.

   Any extension, delay, termination, waiver or amendment of the Offer will be
followed as promptly as practicable by a public announcement. An announcement
in the case of an extension will be made no later than 9:00 a.m., New York City
time, on the next business day after the previously scheduled Expiration Date.
Without limiting the manner in which we may choose to make any public
announcement, subject to applicable law (including Rules 14d-4(d) and 14d-6(c)
promulgated under the Securities Exchange Act, which require that material
changes be promptly disseminated to holders of Shares), we 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 we make a material change in the terms of the Offer, or if we waive a
material condition to the Offer, we will extend the Offer and disseminate
additional tender offer materials to the extent required by Rules 14d-4(d),
14d-6(c) and 14e-1 promulgated under the Securities Exchange Act. The minimum
period during which a tender offer must remain open following material changes
in the terms of the offer, other than a change in price or a change in
percentage of securities sought, depends upon the facts and circumstances,
including the materiality of the changes. In the SEC's view, an offer should
remain open for a minimum of five business days from the date the material
change is first published, sent or given to stockholders, and, if material
changes are made with respect to information that approaches the significance
of price and the percentage of securities sought, a minimum of ten business
days may be required to allow for adequate dissemination and investor

                                       3


response. With respect to a change in price, a minimum ten-business-day period
from the date of the change is generally required to allow for adequate
dissemination to stockholders. Accordingly, if prior to the Expiration Date, we
decrease the number of Shares being sought, or increase or decrease the
consideration offered pursuant to the Offer, and if the Offer is scheduled to
expire at any time earlier than the period ending on the tenth business day
from the date that notice of the increase or decrease is first published, sent
or given to holders of Shares, we will extend the Offer at least until the
expiration of that period of ten business days. For purposes of the Offer, a
"business day" means any day other than a Saturday, Sunday or a U.S. federal
holiday and consists of the time period from 12:01 a.m. through 12:00 midnight,
New York City time.

   The Offer is conditioned upon, among other things, the satisfaction of the
Minimum Condition.

   Consummation of the Offer is also conditioned upon expiration or termination
of the other conditions set forth in Section 14. We reserve the right (but are
not obligated), in accordance with applicable rules and regulations of the SEC
and with the Merger Agreement, to waive any or all of those conditions, except
for the Minimum Condition. If, by the Expiration Date, any or all of those
conditions have not been satisfied, we may, in the exercise of our good faith
judgment, elect to (a) extend the Offer and, subject to applicable withdrawal
rights, retain all tendered Shares until the expiration of the Offer, as
extended, subject to the terms of the Offer and the Merger Agreement; (b) waive
all of the unsatisfied conditions (other than the Minimum Condition) and,
subject to complying with applicable rules and regulations of the SEC, accept
for payment all Shares so tendered; or (c) terminate the Offer and not accept
for payment any Shares and return all tendered Shares to tendering
stockholders. In the event that we waive any condition set forth in Section 14,
the SEC may, if the waiver is deemed to constitute a material change to the
information previously provided to the stockholders, require that the Offer
remain open for an additional period of time and/or that we disseminate
information concerning such waiver.

   Lifschultz has provided us with its stockholder lists and security position
listings for the purpose of disseminating the Offer to holders of Shares. We
will mail this Offer to Purchase, the related Letter of Transmittal and other
relevant materials to record holders of Shares and we will furnish the
materials to brokers, dealers, commercial banks, trust companies and similar
persons whose names, or the names of whose nominees, appear on the security
holder lists or, if applicable, who are listed as participants in a clearing
agency's security position listing, for forwarding to beneficial owners of
Shares.

   Subsequent Offering Period. We reserve the right (but are not obligated) in
accordance with the Merger Agreement and applicable rules and regulations of
the SEC, to provide a subsequent offering period of three business days to 20
business days after the expiration of the initial offering period of the Offer
and our purchase of Shares tendered in the Offer. A subsequent offering period
would give stockholders who do not tender in the initial offering period of the
Offer another opportunity to tender their Shares and receive the same offer
price. A subsequent offering period, if one is provided, is not an extension of
the Offer, which already will have been completed. If we elect to provide a
subsequent offering period, we will disseminate additional tender offer
materials. The SEC has stated its view that the initial offering period of the
Offer should remain open generally for a minimum of five business days from the
date information regarding a subsequent offering period is first published,
sent or given to stockholders. During a subsequent offering period,
stockholders will not have withdrawal rights, and we will promptly purchase and
pay for any Shares tendered at the same price paid in the Offer.

2. Acceptance for Payment and Payment.

   Upon the terms and subject to the conditions of the Offer (including, if we
extend or amend the Offer, the terms and conditions of the Offer as so extended
or amended), we will purchase, by accepting for payment, and will pay for, all
Shares validly tendered and not withdrawn (as permitted by Section 4) prior to
the Expiration Date promptly after the later of (a) the Expiration Date and (b)
the satisfaction or waiver of the conditions to the Offer set forth in Section
14. In addition, subject to applicable rules of the SEC, we reserve the right
to

                                       4


delay acceptance for payment of, or payment for, Shares pending receipt of any
regulatory or governmental approvals specified in Section 15.

   For information with respect to approvals that we are required to obtain
prior to the completion of the Offer, see Section 15.

   In all cases, we will pay for Shares purchased in the Offer only after
timely receipt by the Depositary of (a) certificates representing the Shares
("Share Certificates") or timely confirmation (a "Book-Entry Confirmation") of
the book-entry transfer of the Shares into the Depositary's account at The
Depository Trust Company (the "Book-Entry Transfer Facility") pursuant to the
procedures set forth in Section 3; (b) the appropriate Letter of Transmittal
(or a facsimile), 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 (c) any other documents that the Letter of
Transmittal requires.

   "Agent's Message" means a message transmitted by a Book-Entry Transfer
Facility to, and received by, the Depositary and forming a part of a Book-Entry
Confirmation, which message 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 the Book-Entry
Confirmation that the participant has received and agrees to be bound by the
terms of the Letter of Transmittal and that we may enforce that agreement
against the participant.

   For purposes of the Offer, we will be deemed to have accepted for payment,
and purchased, Shares validly tendered and not withdrawn as, if and when we
give oral or written notice to the Depositary of our acceptance of the Shares
for payment pursuant to the Offer. In all cases, upon the terms and subject to
the conditions of the Offer, payment for Shares purchased pursuant to the Offer
will be made by deposit of the purchase price for the Shares with the
Depositary, which will act as agent for tendering stockholders for the purpose
of receiving payment from us and transmitting payment to validly tendering
stockholders.

   Under no circumstances will we pay interest on the purchase price for
Shares.

   If we do not purchase any tendered Shares pursuant to the Offer for any
reason, or if you submit Share Certificates representing more Shares than you
wish to tender, we will return Share Certificates representing unpurchased or
untendered Shares, without expense to you (or, in the case of Shares delivered
by book-entry transfer into the Depositary's account at a Book-Entry Transfer
Facility pursuant to the procedures set forth in Section 3, the Shares will be
credited to an account maintained within the Book-Entry Transfer Facility), as
promptly as practicable following the expiration, termination or withdrawal of
the Offer.

   If, prior to the Expiration Date, we increase the price offered to holders
of Shares in the Offer, we will pay the increased price to all holders of
Shares that we purchase in the Offer, whether or not the Shares were tendered
before the increase in price.

   We reserve the right, subject to the provisions of the Merger Agreement, to
transfer or assign, in whole or from time to time in part, to one or more of
our subsidiaries or affiliates the right to purchase all or any portion of the
Shares tendered in the Offer, but any such transfer or assignment will not
relieve us of our obligations under the Offer or prejudice your rights to
receive payment for Shares validly tendered and accepted for payment in the
Offer.

3. Procedures for Accepting the Offer and Tendering Shares.

   Valid Tender of Shares. Except as set forth below, in order for you to
tender Shares in the Offer, the Depositary must receive the Letter of
Transmittal (or a facsimile), properly completed and signed, together with any
required signature guarantees or an Agent's Message in connection with a book-
entry delivery of Shares and any other documents that the Letter of Transmittal
requires at one of its addresses set forth on the back

                                       5


cover of this Offer to Purchase on or prior to the Expiration Date or the
expiration of the subsequent offering period, as the case may be, and either
(a) you must deliver Share Certificates representing tendered Shares to the
Depositary or you must cause your Shares to be tendered pursuant to the
procedure for book-entry transfer set forth below and the Depositary must
receive Book-Entry Confirmation, in each case on or prior to the Expiration
Date or the expiration of the subsequent offering period, as the case may be,
or (b) you must comply with the guaranteed delivery procedures set forth below.

   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 your option and sole risk, and delivery will be
considered made only when the Depositary actually receives the certificates. If
delivery is by mail, registered mail with return receipt requested, properly
insured, is recommended. In all cases, you should allow sufficient time to
ensure timely delivery.

   Book-Entry Transfer. The Depositary will make a request to establish
accounts 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 the Shares into the Depositary's
account at the Book-Entry Transfer Facility in accordance with the Book-Entry
Transfer Facility's procedures. However, although Shares may be delivered
through book-entry transfer into the Depositary's account at the Book-Entry
Transfer Facility, the Depositary must receive the Letter of Transmittal (or
facsimile), properly completed and signed, with any required signature
guarantees, or an Agent's Message in connection with a book-entry transfer, and
any other required documents, at one of its addresses set forth on the back
cover of this Offer to Purchase on or before the Expiration Date or the
expiration of the subsequent offering period, as the case may be, or you must
comply with the guaranteed delivery procedure set forth below.

   Delivery of documents to the Book-Entry Transfer Facility in accordance the
Book-Entry Transfer Facility's procedures does not constitute delivery to the
Depositary.

   Signature Guarantees. A bank, broker, dealer, credit union, savings
association or other entity which is a member in good standing of a recognized
Medallion Program approved by the Securities Transfer Association Inc.,
including the Securities Transfer Agents Medallion Program (STAMP), the Stock
Exchange Medallion Program (SEMP) and the New York Stock Exchange Medallion
Signature Program (MSP) or any other "eligible guarantor institution" (as such
term is defined in Rule 17Ad-15 under the Securities Exchange Act of 1934, as
amended) (an "Eligible Institution") must guarantee signatures on all Letters
of Transmittal, unless the Shares tendered are tendered (a) by a registered
holder of Shares who has not completed either the box labeled "Special Payment
Instructions" or the box labeled "Special Delivery Instructions" on the Letter
of Transmittal or (b) for the account of an Eligible Institution. See
Instruction 1 of the Letter of Transmittal.

   If the Share Certificates are registered in the name of a person other than
the signer of the Letter of Transmittal, or if payment is to be made to, or
Share Certificates for unpurchased Shares are to be issued or returned to, a
person other than the registered holder, then the tendered Share Certificates
must be endorsed or accompanied by appropriate stock powers, signed exactly as
the name or names of the registered holder or holders appear on the Share
Certificates, with the signatures on the Share Certificates or stock powers
guaranteed by an Eligible Institution as provided in the Letter of Transmittal.
See Instructions 1 and 5 of the Letter of Transmittal.

   If the Share Certificates are forwarded separately to the Depositary, a
properly completed and duly executed Letter of Transmittal (or facsimile) must
accompany each delivery of Share Certificates.

   Guaranteed Delivery. If you want to tender Shares in the Offer and your
Share Certificates are not immediately available or time will not permit all
required documents to reach the Depositary on or before the

                                       6


Expiration Date or the procedures for book-entry transfer cannot be completed
on time, your Shares may nevertheless be tendered if you comply with all of the
following guaranteed delivery procedures:

     (a) your tender is made by or through an Eligible Institution;

     (b) the Depositary receives, as described below, a properly completed
  and signed Notice of Guaranteed Delivery, substantially in the form made
  available by us, on or before the Expiration Date; and

     (c) the Depositary receives the Share Certificates (or a Book-Entry
  Confirmation) representing all tendered Shares, in proper form for transfer
  together with a properly completed and duly executed Letter of Transmittal
  (or facsimile), 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 within three Nasdaq National Market trading
  days after the date of execution of the Notice of Guaranteed Delivery.

   You may deliver the Notice of Guaranteed Delivery by hand or mail or by
facsimile transmission to the Depositary. The Notice of Guaranteed Delivery
must include a guarantee by an Eligible Institution in the form set forth in
the Notice of Guaranteed Delivery. Guaranteed delivery procedures are not
available in the subsequent offering period.

   Notwithstanding any other provision of the Offer, we will pay for Shares
only after timely receipt by the Depositary of Share Certificates for, or of
Book-Entry Confirmation with respect to, the Shares, a properly completed and
duly executed Letter of Transmittal (or facsimile thereof), together with any
required signature guarantees (or, in the case of a book-entry transfer, an
Agent's Message) and any other documents required by the appropriate Letter of
Transmittal. Accordingly, payment might not be made to all tendering
stockholders at the same time, and will depend upon when the Depositary
receives Share Certificates or Book-Entry Confirmation that the Shares have
been transferred into the Depositary's account at a Book-Entry Transfer
Facility.

   Backup U.S. Federal Income Tax Withholding. In order to avoid "backup
withholding" of federal income tax on payments of cash pursuant to the Offer or
the Merger, you must, unless an exemption applies, provide the Depositary with
your correct taxpayer identification number ("TIN") on a Substitute Form W-9
included in the Letter of Transmittal and certify under penalties of perjury
that such TIN is correct and that you are not subject to backup withholding. If
you do not provide your correct TIN or you fail to provide the certifications
described above, the IRS may impose a penalty on you and the payment of cash to
you pursuant to the Offer or the Merger may be subject to backup withholding of
31% of the amount of such payment. All stockholders surrendering Shares
pursuant to the Offer should complete and sign the main signature form and the
Substitute Form W-9 included as part of the Letter of Transmittal to provide
the information and certification necessary to avoid backup withholding (unless
an applicable exemption exists and is proved in a manner satisfactory to us and
the Depositary).

   Certain stockholders, including certain corporations and foreign
individuals, are not subject to these backup withholding and reporting
requirements. In order for a foreign individual to qualify as an exempt
recipient, however, he or she must submit, if eligible, a Certificate of
Foreign Status on Form W-8BEN attesting to his or her exempt status. See
Instruction 9 of the Letter of Transmittal.

   Appointment as Proxy. By executing the Letter of Transmittal, you
irrevocably appoint our designees, and each of them, as your agents, attorneys-
in-fact and proxies, with full power of substitution, in the manner set forth
in the Letter of Transmittal, to the full extent of your rights with respect to
the Shares that you tender and that we accept for payment and with respect to
any and all other Shares and other securities or rights issued or issuable in
respect of those Shares on or after the date of this Offer to Purchase. All
such powers of attorney and proxies will be considered irrevocable and coupled
with an interest in the tendered Shares. This appointment will be effective
when we accept your Shares for payment in accordance with the terms of the
Offer. Upon such acceptance for payment, all other powers of attorney and
proxies given by you with respect to your Shares and such other securities or
rights prior to such payment will be revoked, without further action, and no
subsequent powers of attorney and proxies may be given by you (and, if given,
will not be deemed effective). Our designees will, with respect to the Shares
and such other securities and rights for which the

                                       7


appointment is effective, be empowered to exercise all your voting and other
rights as they in their sole discretion may deem proper at any annual or
special meeting of Lifschultz's stockholders, or any adjournment or
postponement thereof, or by written consent in lieu of any such meeting or
otherwise. In order for Shares to be deemed validly tendered, immediately upon
the acceptance for payment of such Shares, we or our designee must be able to
exercise full voting rights with respect to such Shares and other securities,
including voting at any meeting of Lifschultz's stockholders.

   Determination of Validity. All questions as to the form of documents and the
validity, eligibility (including time of receipt) and acceptance for payment of
any tender of Shares will be determined by us, in our sole discretion, which
determination will be final and binding on all parties. We reserve the absolute
right to reject any or all tenders determined by us not to be in proper form or
the acceptance of or payment for which may, in the opinion of our counsel, be
unlawful. We also reserve the absolute right to waive any of the conditions of
the Offer or any defect or irregularity in any tender of Shares of any
particular stockholder whether or not similar defects or irregularities are
waived in the case of other stockholders.

   Our interpretation of the terms and conditions of the Offer will be final
and binding. No tender of Shares will be deemed to have been validly made until
all defects and irregularities with respect to the tender have been cured or
waived by us. None of Danaher, the Purchaser or any of their respective
affiliates or assigns, the Depositary, the Information Agent or any other
person or entity will be under any duty to give any notification of any defects
or irregularities in tenders or incur any liability for failure to give any
such notification.

   Our acceptance for payment of Shares tendered pursuant to any of the
procedures described above will constitute a binding agreement between us and
you upon the terms and subject to the conditions of the Offer.

4. Withdrawal Rights.

   Except as described in this Section 4, tenders of Shares made in the Offer
are irrevocable. You may withdraw Shares that you have previously tendered in
the Offer at any time on or before the Expiration Date and, unless theretofore
accepted for payment as provided herein, may also be withdrawn at any time
after July 20, 2001. You may not withdraw Shares during any subsequent offering
period. See Section 1.

   If, for any reason, acceptance for payment of any Shares tendered in the
Offer is delayed, or we are unable to accept for payment or pay for Shares
tendered in the Offer, then, without prejudice to our rights set forth in this
Offer to Purchase, the Depositary may, nevertheless, on our behalf, retain
Shares that you have tendered, and you may not withdraw your Shares except to
the extent that you are entitled to and duly exercise withdrawal rights as
described in this Section 4. Any such delay will be by an extension of the
Offer to the extent required by law.

   In order for your withdrawal to be effective, you must deliver a written or
facsimile transmission notice of withdrawal to 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 your name, the number of Shares that you want
to withdraw, and (if Share Certificates have been tendered) the name of the
registered holder of the Shares as shown on the Share Certificate, if different
from your name. If Share Certificates have been delivered or otherwise
identified to the Depositary, then prior to the physical release of such Share
Certificates, you must submit the serial numbers shown on the particular Share
Certificates evidencing the Shares to be withdrawn and an Eligible Institution
must guarantee the signature on the notice of withdrawal, except in the case of
Shares tendered for the account of an Eligible Institution. If Shares have been
tendered pursuant to the procedures for book-entry transfer set forth in
Section 3, the notice of withdrawal must specify the name and number of the
account at the Book-Entry Transfer Facility to be credited with the withdrawn
Shares, in which case a notice of withdrawal will be effective if delivered to
the Depositary by any method of delivery described in the first sentence of
this paragraph. You may not rescind a withdrawal of Shares. Any Shares that you
withdraw will be considered not validly tendered for purposes of the Offer, but
you may tender your Shares again at any time before the Expiration Date by
following any of the procedures described in Section 3.


                                       8


   All questions as to the form and validity (including time of receipt) of
notices of withdrawal will be determined by us, in our sole discretion, which
determination will be final and binding. None of Danaher, the Purchaser or any
of their respective affiliates or assigns, the Depositary, the Information
Agent or any other person or entity will be under any duty to give any
notification of any defects or irregularities in any notice of withdrawal or
incur any liability for failure to give any such notification.

5. Material U.S. Federal Income Tax Consequences.

   Your receipt of cash for Shares in the Offer or the Merger will be a taxable
transaction for U.S. federal income tax purposes, and may also be a taxable
transaction under applicable state, local, foreign and other tax laws. For U.S.
federal income tax purposes, if you sell or exchange your Shares in the Offer
or the Merger, you would generally recognize gain or loss equal to the
difference between the amount of cash received and your tax basis for the
Shares that you sold or exchanged. That gain or loss will be capital gain or
loss (assuming you hold your Shares as a capital asset). Any such capital gain
or loss will be long term if, as of the date of sale or exchange, you have held
such Shares for more than one year, or will be short term if, as of such date,
you have held such Shares for one year or less. A stockholder's ability to use
capital losses to offset ordinary income is limited.

   Under U.S. federal income tax backup withholding rules, unless an exemption
applies, we will be required to withhold 31% of all payments to which you are
entitled pursuant to the Offer or the Merger, unless you provide a tax
identification number and certify under penalties of perjury that the number is
correct. If you are an individual, the tax identification number is your social
security number. If you are not an individual, the tax identification number is
your employer identification number. A stockholder that does not furnish its
taxpayer identification number, or that does not otherwise establish a basis
for an exemption from backup withholding, may be subject to a penalty imposed
by the IRS. You should complete and sign the Substitute Form W-9, which will be
included with the Letter of Transmittal to be returned to the Depositary, in
order to provide the information and certification necessary to avoid backup
withholding, unless an applicable exception exists and is proved in a manner
satisfactory to the Depositary. Backup withholding is not an additional tax.
Rather, the amount of the backup withholding can be credited against the U.S.
federal income tax liability of the person subject to the backup withholding,
provided that the required information is given to the IRS.

   The foregoing U.S. federal income tax discussion may not be applicable to
certain types of stockholders, including stockholders who acquired Shares
through the exercise of employee stock options or otherwise as compensation,
individuals who are not citizens or residents of the United States, foreign
corporations and other foreign entities, and entities that are otherwise
subject to special tax treatment under the Internal Revenue Code, such as
insurance companies, tax-exempt organizations, regulated investment companies
and financial institutions. This discussion may also not be applicable to
stockholders that are subject to special tax rules based on their own
individual circumstances.

   The U.S. federal income tax discussion set forth above is based upon laws,
regulations, rulings and decisions now in effect, all of which are subject to
change, possibly retroactively. You are urged to consult your own tax advisor
with respect to the tax consequences of the Offer and the Merger, including the
application and effect of state, local or foreign income or other tax laws.

                          LIFSCHULTZ INDUSTRIES, INC.

   No cash dividends have been declared or paid on any of the Shares during the
quarters indicated. In addition, under the terms of the Merger Agreement,
Lifschultz is not permitted to declare or pay dividends with respect to any of
the Shares prior to the Effective Time. See Section 13.

   On May 15, 2001, the last full day of trading prior to the announcement of
the execution of the Merger Agreement, the reported closing price on the Nasdaq
SmallCap Market for the Shares was $19.00 per Share. On May 18, 2001, the last
full day of trading prior to the printing of this Offer to Purchase, the
reported closing price on the Nasdaq SmallCap Market for the Shares was $22.63
per Share.

   Stockholders are urged to obtain current market quotations for the Shares.

7. Possible Effects of the Offer on the Market for the Shares; Nasdaq SmallCap
   Market Quotation; Securities Exchange Act Registration; Margin Regulations.

   Possible Effects of the Offer on the Market for the Shares. The purchase of
Shares pursuant to the Offer will reduce the number of Shares that might
otherwise trade publicly and could adversely affect the liquidity and market
value of the remaining Shares held by the public. The purchase of Shares
pursuant to the Offer can also be expected to reduce the number of holders of
Shares. We cannot predict whether the reduction in the number of Shares that
might otherwise trade publicly would have an adverse or beneficial effect on
the market price for or marketability of the Shares or whether it would cause
future market prices to be greater or less than the Offer price.

   Stock Quotation. Depending upon the number of Shares purchased pursuant to
the Offer, the Shares may no longer meet the requirements of the Nasdaq
SmallCap Market for continued quotation on the Nasdaq SmallCap Market.
According to the Nasdaq SmallCap Market's published guidelines, the Nasdaq
SmallCap Market would consider suspending quotation of the Shares if, among
other things, (a) the number of record holders of 100 or more Shares should
fall below 300; (b) the number of publicly held Shares (exclusive of direct or
indirect holdings of Danaher, Purchaser, any other subsidiaries or affiliates
of Danaher, any officers or directors of Lifschultz or their immediate
families, or any beneficial owner of more than 10% of the total outstanding
Shares ("Excluded Holdings")) should fall below 500,000; or (c) the aggregate
market value of such publicly held Shares (exclusive of Excluded Holdings)
should fall below $1,000,000. If, as a result of the purchase of Shares
pursuant to the Offer or otherwise, the Shares no longer meet the requirements
of the Nasdaq SmallCap Market for continued quotation and the quotation of the
Shares is discontinued, the market for the Shares could be adversely affected.

                                       10


   If the Nasdaq SmallCap Market were to suspend quotation of the Shares, it is
possible that the Shares would trade on another securities exchange or continue
in the over-the-counter market and that price or other quotations would be
reported by such exchange or through other sources. The extent of the public
market for the Shares and the availability of such quotations would depend upon
such factors as the number of stockholders and/or the aggregate market value of
the publicly traded Shares remaining at such time, the interest in maintaining
a market in the Shares on the part of securities firms, the possible
termination of registration under the Securities Exchange Act as described
below and other factors. We cannot predict whether the reduction in the number
of Shares that might otherwise trade publicly would have an adverse or
beneficial effect on the market price for or marketability of the Shares or
whether it would cause future market prices to be greater or less than the
Offer price.

   Securities Exchange Act Registration. The Shares are currently registered
under the Securities Exchange Act. The purchase of Shares by the Purchaser
pursuant to the Offer may result in the Shares becoming eligible for
deregistration under the Securities Exchange Act. Registration of the Shares
under the Securities Exchange Act may be terminated upon application by
Lifschultz to the SEC if the Shares are not listed on a "national securities
exchange" and there are fewer than 300 record holders of Shares. Termination of
registration of the Shares under the Securities Exchange Act would
substantially reduce the information that Lifschultz is required to furnish to
its stockholders and the SEC and would make certain provisions of the
Securities Exchange Act, such as the short-swing profit recovery provisions of
Section 16(b) of the Securities Exchange Act and the requirements of furnishing
a proxy statement in connection with stockholders' meetings pursuant to Section
14(a) or 14(c) of the Securities Exchange Act and the related requirement of an
annual report, no longer applicable to Lifschultz. If the Shares are no longer
registered under the Securities Exchange Act, the requirements of Rule 13e-3
promulgated under the Securities Exchange Act with respect to "going private"
transactions would no longer be applicable to Lifschultz. In addition, the
ability of "affiliates" of Lifschultz and persons holding "restricted
securities" of Lifschultz to dispose of such securities pursuant to Rule 144
promulgated under the Securities Act of 1933, as amended, may be impaired or,
with respect to certain persons, eliminated. If registration of the Shares
under the Securities Exchange Act were terminated, the Shares would no longer
be "margin securities" or eligible for stock exchange listing or Nasdaq
SmallCap Market reporting. We believe that the purchase of Shares pursuant to
the Offer may result in the Shares becoming eligible for deregistration under
the Securities Exchange Act, and it would be our intention to cause Lifschultz
to make an application for termination of registration of the Shares as soon as
possible after successful completion of the Offer if the Shares are then
eligible for such termination.

   If registration of the Shares is not terminated prior to the Merger, then
the registration of the Shares under the Securities Exchange Act and the
quotation of the Shares on the Nasdaq SmallCap Market will be terminated
following the completion of the Merger.

   Margin Regulations. The Shares are currently "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System, which
regulations have the effect, among other things, of allowing brokers to extend
credit on the collateral of the Shares for the purpose of buying, carrying or
trading in securities ("Purpose Loans"). Depending upon factors such as the
number of record holders of the Shares and the number and market value of
publicly held Shares, following the purchase of Shares pursuant to the Offer,
the Shares might no longer constitute "margin securities" for purposes of the
Federal Reserve Board's margin regulations and, therefore, could no longer be
used as collateral for Purpose Loans made by brokers. In addition, if
registration of the Shares under the Securities Exchange Act were terminated,
the Shares would no longer constitute "margin securities."

10. Background of the Offer; Contacts with Lifschultz.

   During 1998 and 1999, Fluke Corporation, an indirect, wholly-owned
subsidiary of Danaher ("Fluke") and Hart conducted discussions to establish an
arrangement whereby Hart would produce Hart dry well temperature calibrators
for Fluke under the Fluke brand name. Fluke entered into an agreement with Hart
on August 6, 1999, wherein Fluke agreed to buy certain instruments from Hart at
certain fixed prices and in certain estimated quantities. Fluke paid Hart
approximately $56,000 under the agreement for Lifschultz's fiscal year ended
July 31, 2000 and has paid Hart approximately $145,000 from August 1, 2000
through April 30, 2001.

   In August 2000, after establishing the aforementioned arrangement, Mr. James
C. Triplett, the Chairman and Chief Executive Officer of Hart, indicated to Mr.
Tom Johnson, Fluke Precision Measurement Business Manager, that David K.
Lifschultz, the Chairman of the Board and largest shareholder of Lifschultz,
was considering selling Lifschultz. Mr. Triplett inquired whether Fluke and
Danaher were interested in exploring a potential purchase of Lifschultz.
Several weeks later, Mr. Johnson indicated to Mr. Triplett that Fluke and
Danaher needed to perform further research before responding to Mr. Triplett's
inquiry.

   In November 2000, Mr. Johnson and Mr. Warren Wong, Fluke's engineering
manager, visited Hart's facilities in Utah to learn more about its operations.

   In December 2000, Mr. Chris Eppel, Danaher Director of Business Development,
Mr. James Cavoretto, Vice President, Worldwide Engineering of Fluke, and Mr.
Johnson met with Mr. Triplett at Hart. Mr. Eppel indicated to Mr. Triplett
Danaher's initial interest in pursuing discussions to purchase Hart or possibly
all of Lifschultz. Mr. Triplett discussed with Messrs. Eppel, Cavoretto and
Johnson the business outlook of Hart and the operations of Lifschultz.

   On January 26, 2001, Mr. Paul Burgon, Danaher Manager of Corporate
Development, and Mr. Eppel called Mr. Triplett to indicate that Danaher would
consider purchasing all the outstanding shares of Lifschultz for a gross
purchase price of $28-30 million, subject to Danaher Board approval,
satisfactory due diligence and negotiation of a definitive agreement between
Lifschultz and Danaher. Mr. Triplett made a counter offer to Mr. Burgon of $35
million subject to the same requirements.

   On February 27, 2000, Danaher signed a confidentiality agreement with Hart.

   Mr. James Lico, President of Fluke, Mr. Eppel, Mr. Johnson, Mr. Burgon and
certain other Fluke managers visited Hart at various times between February 26,
2001 and March 27, 2001 to conduct further due diligence

                                       13


on Lifschultz and Hart. During these visits, Danaher and Fluke representatives
met with Mr. Dennis Hunter, President, Chief Financial Officer and director of
Lifschultz and President and Chief Executive Officer of CSC, to discuss the
business prospects of CSC as well as certain matters regarding Lifschultz's
corporate structure as a whole.

   On March 1, 2001, Danaher's Board of Directors reviewed the business of
Lifschultz and a summary of the negotiations between the parties up to that
date. At that time, the Board unanimously approved the acquisition of
Lifschultz, subject to satisfactory completion of due diligence and negotiation
of a definitive agreement on acceptable terms.

   Over a period of several weeks following March 1, 2001, Mr. Burgon and Mr.
Triplett spoke at various times to discuss the proposed purchase price and the
overall structure of the proposed transaction, in each case subject to
satisfactory due diligence and agreement on other terms.

   Between March 13, 2001 and May 15, 2001, Danaher conducted legal due
diligence on Lifschultz and its subsidiaries.

   Lifschultz has advised Danaher as follows: On April 16, 2001, the Lifschultz
Board met with Mr. Triplett, at which time Mr. Triplett briefed the Lifschultz
Board on all aspects of the contacts and negotiations to date with the Parent.
The Lifschultz Board reviewed information from Houlihan and Mr. Triplett on
various aspects of the transaction and the negotiations, after which the
Lifschultz Board unanimously approved the transaction, subject to satisfactory
negotiation of a definitive agreement on acceptable terms. The Lifschultz Board
further authorized Mr. Triplett to continue negotiations and execute a letter
of intent with the Parent.

   On April 17, 2001, Danaher and Lifschultz signed a letter of intent relating
to the purchase of Lifschultz by Danaher. The letter of intent contemplated
that Danaher would pay a per share purchase price of approximately $22.80 and
approximately $2.8 million in Lifschultz transaction-related expenses. In
addition, the letter of intent contemplated that Danaher would pay additional
amounts for noncompetition and consulting agreements with certain executive
officers of Lifschultz and Hart. The letter of intent was non-binding, except
that Lifschultz was prohibited from conducting discussions relating to a
business combination with other parties for a period of 60 days from the date
of the letter of intent.

   Between April 19, 2001 and May 15, 2001, Danaher and Lifschultz negotiated
the Merger Agreement and the Stockholders' Agreement and the consulting and
noncompetition agreements to be entered into with Messrs. Triplett, Lifschultz,
Hunter and J. Randall Owen.

   On May 1, 2001, the Danaher Board of Directors reviewed the progress of the
proposed transaction with Lifschultz.

   Lifschultz has advised Danaher as follows: On May 15, 2001, the Lifschultz
Board of Directors was presented with the form of Merger Agreement and terms of
the proposed transaction. At this meeting, Houlihan also delivered to the
Lifschultz Board its opinion as to the fairness, from a financial point of
view, to the disinterested stockholders of Lifschultz of the per share amount
to be paid in the Offer and Merger. After full discussion, the Lifschultz Board
unanimously determined that the Merger Agreement and each of the transactions
contemplated thereby were advisable, fair to and in the best interests of
Lifschultz and its stockholders and approved the Offer and the Merger and
adopted the Merger Agreement.

   The Merger Agreement, the Stockholders' Agreement and the consulting and
noncompetition agreements were finalized and signed by the applicable parties
after the close of business on May 15, 2001. The Merger Agreement provided for
a per share purchase price in the Offer and the Merger of $22.80 and
approximately $3.2 million in Lifschultz transaction-related expenses. Press
releases announcing the transaction were issued by Danaher, Fluke and
Lifschultz between 8:00 and 8:30 a.m. Eastern Time on May 16, 2001.


                                       14


11. Purpose of the Offer; the Merger Agreement; the Stockholders' Agreement;
    Consulting, Employment and Other Agreements; Statutory Requirements;
    Appraisal Rights; Plans for Lifschultz; "Going Private" Transactions.

   (a) Purpose. The purpose of the Offer and the Merger is to acquire control
of, and the entire equity interest in, Lifschultz. The Offer, as the first step
in the acquisition of Lifschultz, is intended to facilitate the acquisition of
all of the Shares. The purpose of the Merger is to acquire all capital stock of
Lifschultz not purchased pursuant to the Offer or otherwise.

   (b) The Merger Agreement. The following summary description of the Merger
Agreement is qualified in its entirety by reference to the Merger Agreement
itself, which we have filed as an exhibit to the Tender Offer Statement on
Schedule TO that we have filed with the SEC, which you may examine and copy as
set forth in Section 8 above (except that it will not be available at the
regional offices of the SEC).

   The Offer. The Merger Agreement provides that the Purchaser will commence
the Offer and that, upon the terms and subject to prior satisfaction or waiver
of the conditions of the Offer, as set forth in Section 14, the Purchaser will
purchase all Shares validly tendered and not withdrawn pursuant to the Offer.
The Merger Agreement provides that, without the prior written consent of
Lifschultz, the Purchaser will not (a) decrease the Offer price or change the
form of consideration payable in the Offer, (b) decrease the number of Shares
sought to be purchased in the Offer, (c) impose additional conditions to the
Offer, (d) waive the Minimum Condition or (e) amend any other term of the Offer
in a manner adverse to the holders of Shares. The Purchaser may extend the
Offer, from time to time, if, at the then-scheduled Expiration Date of the
Offer, any of the conditions to the Purchaser's obligation to accept for
payment and pay for all Shares validly tendered shall not have been satisfied
or waived. In addition, if all conditions to the Purchaser's obligation to
accept for payment and pay for all Shares validly tendered are satisfied, and
the number of Shares tendered and not withdrawn constitutes less than 90% of
the outstanding Shares, the Purchaser shall have the right, in its sole
discretion, to extend the Offer from time to time for up to a maximum of ten
additional business days in the aggregate for all such extensions beyond the
latest Expiration Date.

   Recommendation. Lifschultz has represented to Danaher in the Merger
Agreement that the board of directors of Lifschultz (the "Lifschultz Board"),
at a meeting duly noticed and called, has unanimously (i) determined that the
Merger Agreement and each of the transactions contemplated thereby, including
each of the Offer and the Merger, is advisable, fair to and in the best
interests of Lifschultz and its stockholders, (ii) approved the Offer and the
Merger and adopted the Merger Agreement in accordance with the GCL, (iii)
resolved to recommend that the stockholders of Lifschultz accept the Offer,
tender their Shares pursuant to the Offer and approve the Merger (if such
approval is required by applicable law), and (iv) taken all other action
necessary to render Section 203 of the GCL inapplicable to the Offer and the
Merger; provided, however, that such recommendation and approval may be
withdrawn, modified or amended only prior to the purchase of Shares and only to
the extent that the Lifschultz Board determines in good faith by majority vote,
after consultation with its outside legal counsel and financial advisor, that
such withdrawal, modification or amendment is reasonably likely to result in a
transaction that is a Superior Proposal (as defined in the Merger Agreement),
and that failure to take such action would constitute a breach of the
Lifschultz Board's fiduciary obligations under applicable law. Lifschultz has
further represented that, as of the date of execution of the Merger Agreement,
Houlihan delivered to the Lifschultz Board its written opinion to the effect
that, as of such date, the cash consideration to be paid pursuant to the Offer
and the Merger is fair to the disinterested stockholders of Lifschultz from a
financial point of view.

   Directors. The Merger Agreement provides that, subject to compliance with
applicable law, Danaher, promptly upon the payment by the Purchaser for Shares
pursuant to the Offer, and from time to time thereafter, is entitled to
designate that number of directors, rounded up to the next whole number, on the
Lifschultz Board as is equal to the product of the total number of directors on
the Lifschultz Board (determined after giving effect to the directors so
elected pursuant to such provisions) multiplied by the percentage that the
aggregate number of Shares beneficially owned by Danaher or its affiliates
bears to the total number of Shares then

                                       15


outstanding. Lifschultz shall, upon request of Danaher, promptly take all
actions necessary to cause designees to be so elected, including, if necessary,
seeking the resignations of one or more existing directors; provided, however,
that prior to the time the Merger becomes effective (the "Effective Time"), the
Lifschultz Board shall always have at least two members who are not officers,
directors, employees or designees of the Purchaser or any of its affiliates,
including Lifschultz ("Purchaser Insiders"). If the number of directors who are
not Purchaser Insiders is reduced below two prior to the Effective Time, the
remaining director who is not a Purchaser Insider will be entitled to designate
a person who is not a Purchaser Insider to fill such vacancy. Following the
election or appointment of Danaher's designees and prior to the Effective Time,
any amendment or termination of the Merger Agreement by Lifschultz, any
extension by Lifschultz of the time for performance of any of the obligations
or other acts of Danaher or the Purchaser or any waiver of any of Lifschultz's
rights or conditions to the consummation of the Merger under the Merger
Agreement, in addition to any required approval thereof by the full Lifschultz
Board, will require the concurrence of a majority of the directors of
Lifschultz then in office who are not Purchaser Insiders (or, in the case where
there are two or fewer directors who are not Purchaser Insiders, the
concurrence of one director who is not a Purchaser Insider) if that amendment,
termination, extension or waiver would be reasonably likely to have an adverse
effect on the minority stockholders of Lifschultz.

   The Merger. The Merger Agreement provides that, at the Effective Time, the
Purchaser will be merged with and into Lifschultz. Following the Merger, the
separate corporate existence of the Purchaser will cease and Lifschultz will
continue as the surviving corporation (the "Surviving Corporation") and an
indirect, wholly-owned subsidiary of Danaher.

   Lifschultz has agreed pursuant to the Merger Agreement that, if requested by
Danaher and required by applicable law or the applicable rules and regulations
of the Nasdaq SmallCap Market in order to consummate the Merger, it will (a)
duly call, give notice of, convene and hold a special meeting of its
stockholders as soon as practicable following the acceptance for payment of and
payment for Shares by the Purchaser pursuant to the Offer for the purpose of
adopting the Merger Agreement; (b) prepare and file with the SEC a preliminary
proxy statement relating to the Merger Agreement, and use its commercially
reasonable efforts (1) to obtain and furnish the information required to be
included by the SEC in the Proxy Statement (as defined herein) and, after
consultation with Danaher, to respond promptly to any comments made by the SEC
with respect to the preliminary proxy statement and to cause a definitive proxy
statement (the "Proxy Statement") to be mailed to its stockholders and (2) to
obtain the necessary approvals of the Merger and adoption of the Merger
Agreement by its stockholders; and (c) (1) subject to the provisions described
under "Recommendation," include in the Proxy Statement the recommendation of
the Lifschultz Board that the stockholders of Lifschultz vote in favor of the
approval of the Merger Agreement, and (2) include in the Proxy Statement the
opinion of Houlihan. Danaher has agreed in the Merger Agreement that it will
vote, or cause to be voted, all of the Shares then owned by it, the Purchaser
or any of its other subsidiaries in favor of the approval of the Merger and the
Merger Agreement.

   In addition, if following expiration of the Offer and satisfaction or waiver
of all of the Tender Offer Conditions (as defined in the Merger Agreement),
applicable laws or the applicable rules and regulations of the Nasdaq SmallCap
Market require a vote of the Lifschultz stockholders in order to consummate the
Merger, Danaher and the Purchaser may, in their sole discretion, in lieu of
having Lifschultz call a special meeting of the stockholders, elect to approve
the Merger by written consent without a meeting of the stockholders, as
permitted by Lifschultz's certificate of incorporation and bylaws. Lifschultz
has agreed to take all actions necessary to permit Danaher and the Purchaser to
take such action by written consent, including without limitation making and
assisting in such filings with the SEC, and preparing and mailing an
information statement and such other materials, as may be required under the
federal securities laws and the GCL.

   The Merger Agreement further provides that, notwithstanding the foregoing,
if Danaher, the Purchaser or any other of Danaher's subsidiaries acquires at
least 90% of the outstanding Shares, pursuant to the Offer or otherwise, the
parties to the Merger Agreement will take all necessary and appropriate action
to cause the Merger to become effective as soon as practicable after the
acceptance for payment of and payment for the

                                       16


Shares by the Purchaser pursuant to the Offer without a meeting of the
stockholders of Lifschultz in accordance with Section 253 of the GCL.

   Charter, Bylaws, Directors and Officers. The certificate of incorporation of
Lifschultz, as in effect immediately prior to the Effective Time, will be the
certificate of incorporation of the Surviving Corporation, until amended
afterward in accordance with the provisions of the certificate of incorporation
of the Surviving Corporation and applicable law; provided, however, that any
such amendments shall be consistent with the rights of directors and officers
to indemnification and insurance as described below under "Indemnification,
Directors' and Officers' Insurance." The bylaws of the Purchaser in effect at
the Effective Time will be the bylaws of the Surviving Corporation, until
afterward amended in accordance with the provisions of the bylaws of the
Surviving Corporation and applicable law. Subject to applicable law, (a) the
directors of the Purchaser immediately prior to the Effective Time will be the
initial directors of the Surviving Corporation and will hold office until their
respective successors are duly elected and qualified, or their earlier death,
resignation or removal, and (b) the officers of the Purchaser immediately prior
to the Effective Time will be the initial officers of the Surviving Corporation
and will hold office until their respective successors are duly elected and
qualified, or their earlier death, resignation or removal.

   Conversion of Securities. By virtue of the Merger and without any action on
the part of the holders of the Shares, at the Effective Time, each Share issued
and outstanding immediately prior to the Effective Time (other than (a) any
Shares held by Danaher, the Purchaser, any wholly-owned subsidiary of Danaher
or the Purchaser, in the treasury of Lifschultz or by any wholly-owned
subsidiary of Lifschultz, which Shares, by virtue of the Merger and without any
action on the part of the holder of those Shares, will be canceled and retired
and will cease to exist with no payment being made with respect thereto, and
(b) Shares held by a holder who has not voted in favor of the Merger and who
has demanded appraisal for those Shares in accordance with the GCL ("Dissenting
Shares")) will be canceled and retired and will be converted into the right to
receive $22.80 (or any higher amount Purchaser determines in its sole
discretion to pay in the Offer) net per Share in cash, payable to the holder of
that Share, without interest (the "Merger Price"), upon surrender of the Share
Certificate formerly representing that Share.

   At the Effective Time, each share of common stock of the Purchaser issued
and outstanding immediately prior to the Effective Time will, by virtue of the
Merger and without any action on the part of the holder thereof, be converted
into and become one validly issued, fully paid and non-assessable share of
common stock, par value $0.001 per share, of the Surviving Corporation.

   The Merger Agreement provides that, prior to the Effective Time, the
Lifschultz Board will adopt appropriate resolutions and take such actions as
may be required to provide for the cancellation, effective at the Effective
Time, of all the outstanding options granted under any stock option or similar
plan of Lifschultz (the "Stock Plans"), or under any agreement, without any
payment therefor except as otherwise discussed in this Section 11. Immediately
prior to the Effective Time, all options (whether vested or unvested) will be
canceled (and to the extent exercisable shall no longer be exercisable) and
will entitle each holder of an option, in cancellation and settlement therefor,
to a payment, if any, in cash by Lifschultz (less any applicable withholding
taxes), at the Effective Time, equal to the product of (a) the total number of
Shares subject to that option and (b) the excess, if any, of the Merger Price
over the exercise price per Share subject to that option.

   Representations and Warranties. Pursuant to the Merger Agreement, Lifschultz
has made customary representations and warranties to Danaher and the Purchaser
with respect to, among other matters, its organization and qualification,
capitalization, subsidiaries, authority, required filings and consents, SEC
filings, financial statements, litigation, compliance with law, applicability
of state takeover statutes, insurance, employee benefit plans and labor
matters, environmental matters, material contracts, opinion of financial

governmental authority relating to the Offer and the Merger, related party
transactions, product recalls, intellectual property, tax status, assets and
properties, relationships with customers and suppliers and the absence of
certain changes with respect to Lifschultz. Danaher and the

                                       17


Purchaser have made customary representations and warranties to Lifschultz with
respect to, among other matters, their organization and qualification,

Schedule 14D-9, the Proxy Statement or the other documents required to be filed
with the SEC or any other governmental authority relating to the Offer and the
Merger, and financing.

   Covenants. The Merger Agreement obligates Lifschultz and its subsidiaries,
from the date of the Merger Agreement until the Effective Time, to conduct
their operations only in the ordinary and usual course of business consistent
with past practice, and obligates Lifschultz and its subsidiaries to use their
commercially reasonable efforts to preserve intact their business
organizations, to keep available the services of their present officers and key
employees and to preserve the goodwill of those having business relationships
with them. The Merger Agreement also contains specific restrictive covenants as
to certain impermissible activities of Lifschultz prior to the Effective Time,
which provide that Lifschultz will not (and will not permit any of its
subsidiaries to) take certain actions without the prior written consent of
Danaher including, among other things, actions related to amendments to the
certificate of incorporation or bylaws of Lifschultz, issuances or sales of its
securities, changes in capital structure, dividends and other distributions,
repurchases or redemptions of securities, material acquisitions or
dispositions, increases in compensation or adoption of new benefit plans and
certain other material events or transactions, subject to specified exceptions.

   Access to Information. The Merger Agreement provides that, until the
Effective Time, Lifschultz will give Danaher and the Purchaser and their
representatives full access, during normal business hours, to the assets,
properties, offices and other facilities and to the books and records of
Lifschultz and its subsidiaries, and will provide Danaher and the Purchaser
copies of documents filed pursuant to U.S. federal or state securities laws
during this period, and, upon reasonable request, financial and operating data
and other information with respect to the business and operations of Lifschultz
and its subsidiaries.

   Efforts. Subject to the terms and conditions provided in the Merger
Agreement, each of Lifschultz, Danaher and the Purchaser will cooperate and use
their respective reasonable efforts to make or cause to be made all filings
necessary or proper under applicable laws and regulations, and to take all
other actions necessary, to consummate and make effective the transactions
contemplated by the Merger Agreement.

   Each of the parties to the Merger Agreement also has agreed to use its
commercially reasonable efforts to obtain as promptly as practicable all
Consents (as defined in the Merger Agreement) of any governmental authorities
or any other person required in connection with, and waivers of any Violations
(as defined in the Merger Agreement) that may be caused by, the consummation of
the transactions contemplated by the Merger Agreement; provided, however, that
Danaher would not be required to, and Lifschultz would not be permitted to
without Danaher's consent, divest, hold separate or otherwise materially
restrict the use or operations of any of their respective businesses or assets,
in order to consummate the transactions contemplated by the Offer and the
Merger Agreement, if such divestiture, restriction or other action would, in
the good faith judgment of Danaher, have a material adverse effect on Danaher
or Lifschultz, as applicable.

   Public Announcements. Under the Merger Agreement, Lifschultz, on the one
hand, and Danaher and the Purchaser, on the other hand, have agreed to use
their respective, commercially reasonable efforts to (1) develop a joint
communications plan with respect to the transactions contemplated by the Merger
Agreement, (2) ensure that all press releases and other public statements with
respect to such transactions are consistent with such plan, and (3) consult
promptly with each other prior to issuing any press release or otherwise making
any public statement with respect to the Offer, the Merger and the other
transactions contemplated by the Merger Agreement, agree to provide to the
other party for review a copy of any such press release or statement, and agree
not to issue any such press release or make any such public statement prior to
such consultation and review, unless required by applicable law or any listing
agreement with a securities exchange.

   Indemnification; Directors' and Officers' Insurance. Pursuant to the Merger
Agreement, Danaher has agreed that from and after the Effective Time, the
certificate of incorporation and the bylaws of the Surviving Corporation will
contain provisions with respect to indemnification and exculpation from
liability that are no

                                       18


less favorable than those provisions set forth in Lifschultz's certificate of
incorporation and bylaws on the date of the Merger Agreement. Danaher has also
agreed not to amend, repeal or otherwise modify these provisions for a period
of six years from the Effective Time in any manner that would adversely affect
the rights thereunder of individuals who on or prior to the Effective Time were
directors, officers, employees or agents of Lifschultz, unless such amendment,
repeal or modification is required by law. Danaher has also agreed that it will
not cancel Lifschultz's directors' and officers' liability insurance policy for
a period of two years immediately following the Effective Time. In the event
that Danaher or the Surviving Corporation consolidates or merges with another
person or transfers its assets to another person, it shall make proper
provisions to assure that these obligations are assumed.

   Notification of Certain Matters. Danaher and Lifschultz have agreed to
promptly notify each other of (a) any circumstance or the occurrence or non-
occurrence of any fact or event which would be reasonably likely (1) to cause
any representation or warranty contained in the Merger Agreement to be untrue
or inaccurate in any material respect at any time prior to the Effective Time,
(2) to cause any covenant, condition or agreement under the Merger Agreement
not to be complied with or satisfied, or (3) to result in a material adverse
effect on Lifschultz, (b) any failure of Lifschultz, Danaher or the Purchaser,
as the case may be, to comply with or satisfy any covenant, condition or
agreement to be complied with or satisfied by it under the Merger Agreement,
and (c) any other material development relating to the business, prospects,
financial condition or results of operations of Lifschultz or any of its
subsidiaries. Each of Lifschultz, Danaher and the Purchaser is also required to
give prompt notice to the other parties of any notice or communication from any
third party alleging that the consent of that third party is or may be required
in connection with the transactions contemplated by the Merger Agreement.

   State Takeover Laws. Lifschultz and the Lifschultz Board have agreed (i) to
take all actions necessary to ensure that no "fair price," "control share
acquisition," "moratorium" or other anti-takeover statute, or similar law, is
or becomes applicable to the Merger Agreement or any of the transactions
contemplated by the Merger Agreement, and (ii) if any such statute or law is or
becomes applicable to the Merger Agreement or any of the transactions
contemplated by the Merger Agreement, to take all actions necessary to ensure
that such transactions contemplated may be consummated as promptly as
practicable on the terms contemplated by the Merger Agreement, and otherwise to
minimize the effect of such statute or law on the transactions contemplated by
the Merger Agreement.

   No Solicitation. The Merger Agreement requires Lifschultz to, and to direct
its affiliates and their respective officers, directors, employees,
representatives and agents to, immediately cease any existing discussions or
negotiations with any parties with respect to any Acquisition Transaction (as
defined below). The Merger Agreement further provides that, prior to the
Effective Time, Lifschultz will not authorize or permit any of its subsidiaries
or any of its or its subsidiaries' directors, officers, employees, agents or
representatives, directly or indirectly, to solicit, initiate or encourage, or
furnish or disclose non-public information in furtherance of, any inquiries or
the making of any proposal with respect to any merger, liquidation,
recapitalization, consolidation or other business combination involving
Lifschultz or its subsidiaries or acquisition of 10% or more of any capital
stock or any material portion of the assets of Lifschultz or of its
subsidiaries, or any combination of the foregoing (other than the Offer and the
Merger) (an "Acquisition Transaction"), or negotiate, explore or otherwise
engage in substantive discussions with any person (other than Danaher, the
Purchaser or their respective directors, officers, employees, agents and
representatives) with respect to any Acquisition Transaction or enter into any
agreement, arrangement or understanding with respect to any Acquisition
Transaction or requiring it to abandon, terminate or fail to consummate the
Merger or any other transaction contemplated by the Merger Agreement; provided,
however, that Lifschultz may, prior to the purchase of Shares pursuant to the
Offer, furnish information to, and negotiate or otherwise engage in substantive
discussions with, any person who has delivered a bona fide written proposal for
an Acquisition Transaction if the Lifschultz Board determines in good faith by
a majority vote, following consultation with outside counsel and financial
advisors, that (1) such a transaction is reasonably likely to result in a
transaction that is superior in comparison to the Offer and the Merger and the
terms of the Merger Agreement to

                                       19


Lifschultz's stockholders from a financial point of view and to Lifschultz,
taking into account the terms and conditions thereof, the likelihood of
consummation and the time required to complete such transaction (a "Superior
Proposal"), and (2) failing to take such action would result in a breach of the
fiduciary duties of the Lifschultz Board under applicable law, provided that
prior to furnishing non-public information to any such party, Lifschultz (a)
shall have entered into a confidentiality agreement containing terms at least
as favorable to Lifschultz as those of the letter agreement dated February 27,
2001 between Danaher and Lifschultz, and (b) shall provide Danaher or the
Purchaser copies of all proposed written agreements, arrangements or
understandings, including the forms of any agreements supplied by third
parties, and all applicable financial statements and evidence of any planned
financing with respect to such Superior Proposal (and a description of all
material oral agreements with respect to such Superior Proposal).

   The Merger Agreement further provides that, from and after the execution of
the Merger Agreement, Lifschultz will immediately advise Danaher in writing of
the receipt, directly or indirectly, of any inquiry or proposal with respect to
an Acquisition Transaction, and of any discussions, negotiations or proposals
relating to an Acquisition Transaction, identify the offeror and furnish to
Danaher a copy of any such proposal, if it is in writing, or a written summary
of any such proposal relating to an Acquisition Transaction if it is not in
writing, and that Lifschultz will promptly advise Danaher of any development
relating to any such proposal, including results of any discussions or
negotiations with respect to that proposal.

   FIRPTA Certificate. Lifschultz has agreed to provide Danaher and the
Purchaser, prior to the Expiration Date, (1) a properly executed certificate
for purposes of satisfying the obligations of Danaher and Purchaser under
Treasury Regulation Section 1.1445-2(c)(3), and (2) a form of notice to the
Internal Revenue Service in accordance with the requirements of Treasury
Regulation Section 1.897-2(h)(2), along with written authorization for Danaher
to deliver such notice form to the Internal Revenue Service on behalf of
Lifschultz.

   Repayment of Loan. Lifschultz has agreed, at or prior to the Closing Date
(as defined in the Merger Agreement), to (1) repay or cause to be repaid all
amounts owed pursuant to the Business Loan Agreement dated January 25, 2001 by
and between Hart and KeyBank National Association, as amended, and the related
promissory note, and under the Loan Agreement dated as of November 3, 1999 by
and between CSC and KeyBank National Association, as amended, and the related
promissory note, and (2) cause all liens with respect to any capital stock of
Hart or any other subsidiary of Lifschultz to be released.

   Conditions to Consummation of the Merger. Pursuant to the Merger Agreement,
the respective obligations of Danaher, the Purchaser and Lifschultz to
consummate the Merger are subject to the satisfaction, at or before the
Effective Time, of each of the following conditions: (a) the stockholders of
Lifschultz will have duly adopted the Merger Agreement in accordance with the
procedures set forth in Lifschultz's certificate of incorporation and bylaws,
if required by applicable law or by the rules and regulations of the Nasdaq
SmallCap Market; (b) the Purchaser will have accepted for payment and paid for
Shares pursuant to the Offer in an amount sufficient to meet the Minimum
Condition and otherwise in accordance with the terms of the Merger Agreement;
(c) the consummation of the Merger will not have been restrained, enjoined or
prohibited by any order, judgment, decree, injunction or ruling of a court of
competent jurisdiction or any governmental authority and there will not be any
statute, rule or regulation enacted, promulgated or deemed applicable to the
Merger by any governmental authority which prevents the consummation of the
Merger, materially impairs the benefits of the Merger to Danaher, or has the
effect of making the acquisition of Shares in the Merger illegal; and (d)
expiration or termination of any waiting period (and any extension thereof)
under any material domestic or foreign statutes or regulations applicable to
the Merger.

   Termination. The Merger Agreement may be terminated and the Merger may be
abandoned at any time prior to the Effective Time, notwithstanding approval
thereof by the stockholders of Lifschultz (with any termination by Danaher also
being an effective termination by the Purchaser):

     (a) by the mutual written consent of Danaher and Lifschultz, by action
  of their respective Boards of Directors;

                                       20


     (b) by Danaher or Lifschultz if the Purchaser shall not have accepted
  for payment and paid for the Shares pursuant to the Offer in accordance
  with the terms of the Offer on or before September 30, 2001 (provided that
  a party may not terminate the Merger Agreement pursuant to this provision
  if such failure to accept for payment and pay for the Shares is due to such
  party's material breach of the Merger Agreement);

     (c) by Danaher or Lifschultz if (1) the Offer is terminated or withdrawn
  pursuant to its terms and the terms of the Merger Agreement without any
  Shares being purchased under the Offer, or (2) the Merger has not been
  completed on or before November 30, 2001; provided, however that neither
  party may terminate the Merger Agreement pursuant to this provision if that
  party has breached the Merger Agreement;

     (d) by Danaher or Lifschultz if any court of competent jurisdiction or
  other governmental authority has issued an order, decree or ruling or taken
  any other action permanently enjoining, restraining or otherwise
  prohibiting the Merger or the acceptance for payment of, or payment for,
  Shares pursuant to the Offer and that order, decree or ruling or other
  action will have become final and nonappealable, provided that the party
  seeking to terminate the Merger Agreement will have used its commercially
  reasonable efforts to remove or lift such order, decree or ruling;

     (e) by Danaher or Lifschultz if, prior to the purchase of Shares
  pursuant to the Offer, the Lifschultz Board shall have determined to
  recommend a Superior Proposal to its stockholders and/or to enter into a
  contract or agreement concerning such Superior Proposal after making the
  determination required by Section 6.9(a) of the Merger Agreement; provided
  that Lifschultz cannot exercise its right to terminate under this paragraph
  (e) (and may not enter into a contract or agreement with respect to any
  Superior Proposal) unless and until (1) Lifschultz shall have provided the
  Purchaser and Danaher written notice at least five business days prior to
  such termination that the Lifschultz Board has authorized and intends to
  effect the termination of the Merger Agreement pursuant to this paragraph
  (e), including copies of all proposed contracts and agreements, including
  the forms of any agreements supplied by third parties, and all applicable
  financial statements and evidence of any planned financing with respect to
  such Superior Proposal (and a description of all material oral agreements
  with respect thereto), (2) the Lifschultz Board shall have determined, in
  good faith and after consultation with its outside legal counsel and
  financial advisors that, at the time of its determination to terminate the
  Merger Agreement and at the end of the five-business day period referred to
  above, (A) the foregoing Acquisition Transaction constitutes a Superior
  Proposal, and (B) failing to take such action would result in a breach of
  the fiduciary duties of the Lifschultz Board under applicable law, (3)
  Lifschultz shall otherwise be in compliance with its obligations under the
  Merger Agreement, and (4) (A) within one business day of termination by
  Danaher, or (B) prior to such termination in the case of Lifschultz,
  Lifschultz shall have paid to Danaher the Termination Fee and the Expense
  Fee described in "Fees and Expenses" below;

     (f) by Danaher prior to the purchase of Shares pursuant to the Offer, if
  the Lifschultz Board (or, with respect to (3) below, Lifschultz) (1) shall
  have withheld, withdrawn or modified (including by amendment of the
  Schedule 14D-9) in any manner adverse to the Purchaser or Danaher its
  approval or recommendation of the Offer, the Merger Agreement or the
  Merger, (2) shall have approved or recommended an Acquisition Transaction,
  (3) shall have breached Section 6.9(a) of the Merger Agreement, (4) shall
  have failed to confirm its approval or recommendation of the Offer, the
  Merger Agreement or the Merger to its stockholders within two business days
  of the receipt of a request from Danaher to do so, or (5) shall have
  resolved to effect any of the foregoing;

     (g) by Danaher prior to the purchase of Shares pursuant to the Offer if
  the Minimum Condition has not been satisfied by the then current Expiration
  Date and on or prior to such Expiration Date an Acquisition Transaction
  shall have been publicly announced or disclosed;

     (h) by Lifschultz, if Purchaser fails to (1) commence the Offer in the
  manner provided in the Merger Agreement, (2) keep the Offer open for a
  specified period of time, to the extent Purchaser is otherwise required to
  keep the Offer open for such specified period of time pursuant to the terms
  and conditions set forth in the Merger Agreement, or (3) purchase Shares
  validly tendered in the Offer, to the extent

                                       21


  Purchaser is otherwise required to purchase such Shares pursuant to the
  terms and conditions set forth in the Merger Agreement;

     (i) by Lifschultz, upon a material breach by Danaher or Purchaser of any
  material covenant or agreement set forth in the Merger Agreement, or upon
  the failure of any representation or warranty of Danaher or Purchaser set
  forth in the Merger Agreement to be true and correct as if such
  representation or warranty were made at the time of such determination
  (except as to any such representation or warranty which speaks as of a
  specific date, which must be untrue or incorrect as of such specific date);
  provided that to the extent that the representation or warranty is not
  qualified by Material Adverse Effect (as defined in the Merger Agreement)
  or any other materiality qualifier, no failure shall be deemed to have
  occurred so long as such failure, taken together with all other such
  failures, does not have a Material Adverse Effect on Danaher, and; provided
  further, that no breach or failure shall be deemed to have occurred so long
  as such breach or failure is satisfied or cured within 20 days after
  Lifschultz notifies Danaher of such breach or failure; or

     (j) by Danaher, upon a material breach by Lifschultz of any material
  covenant or agreement set forth in the Merger Agreement, or upon the
  failure of any representation or warranty of Lifschultz set forth in the
  Merger Agreement to be true and correct as if such representation or
  warranty were made at the time of such determination (except as to any such
  representation or warranty which speaks as of a specific date, which must
  be untrue or incorrect as of such specific date); provided that to the
  extent that the representation or warranty is not qualified by Material
  Adverse Effect or any other materiality qualifier, no failure shall be
  deemed to have occurred so long as such failure, taken together with all
  other such failures, does not have a Material Adverse Effect on Lifschultz,
  and; provided further, that no breach or failure shall be deemed to have
  occurred so long as such breach or failure is satisfied or cured within 20
  days after Danaher or Purchaser notifies Lifschultz of such breach or
  failure.

   In the event of the termination of the Merger Agreement in accordance with
its terms, the Merger Agreement will become void and have no effect, without
any liability on the part of any party or its directors, officers or
stockholders, other than certain specified provisions, which shall survive any
such termination; provided that no party would be relieved from liability for
any breach of or misrepresentation under the Merger Agreement.

   Fees and Expenses. Except as provided below, whether or not the Merger is
consummated, all costs and expenses incurred in connection with the Offer, the
Merger Agreement and the transactions contemplated by the Merger Agreement will
be paid by the party incurring those costs and expenses. In the event that the
Merger Agreement is terminated pursuant to paragraphs (e) or (f) under
"Termination," or is terminated pursuant to paragraph (b) or (c) under
"Termination" at a time when Danaher could have terminated the Merger Agreement
pursuant to paragraph (f) under "Termination," Lifschultz must promptly, and in
any event within one business day after such termination, or in the case of
termination by Lifschultz, prior to such termination, pay Danaher a termination
fee of $1,000,000 (the "Termination Fee"), provided that in no event will more
than one Termination Fee be payable by Lifschultz, plus Danaher's aggregate
expenses not to exceed $400,000 (the "Expense Fee"). In the event that the
Merger Agreement is terminated pursuant to paragraph (g) under "Termination"
and within 12 months of the date of that termination of the Merger Agreement an
Acquisition Transaction is consummated, then Lifschultz must, prior to or
simultaneously with the consummation of that transaction, pay Danaher the
Termination Fee and the Expense Fee.

   Amendment. Subject to the provision described in the last sentence of
"Directors," the Merger Agreement may be amended by Lifschultz, Danaher and the
Purchaser at any time before or after any approval of the Merger Agreement by
the stockholders of Lifschultz but, after any such approval, no amendment will
be made which decreases the price to be paid for any of the Shares in the
Merger or which adversely affects the rights of Lifschultz's stockholders
thereunder without the approval of such stockholders.

   Extension; Waiver. Subject to the Merger Agreement, at any time prior to the
Effective Time, the parties to the Merger Agreement may (a) extend the time for
the performance of any of the obligations or other

                                       22


acts of the other, (b) waive any inaccuracies in the representations and
warranties contained therein of any other party thereto or in any document,
certificate or writing delivered pursuant to the Merger Agreement by any other
party to the Merger Agreement or (c) waive compliance by any other party with
any of the agreements or conditions in the Merger Agreement.

   Effects of Inability to Consummate the Merger. Pursuant to the Merger
Agreement, following the consummation of the Offer and subject to certain other
conditions, the Purchaser will be merged into Lifschultz. If, following the
Offer, approval of Lifschultz's stockholders is required by applicable law in
order to consummate the Merger of the Purchaser into Lifschultz, Lifschultz
will either submit the Merger to Lifschultz's stockholders for approval or take
action by written consent without a meeting of the stockholders, in the
Purchaser's sole discretion. If the Merger is submitted to Lifschultz's
stockholders for approval, the Merger will require the approval of the holders
of not less than a majority of the outstanding Shares, including the Shares
owned by the Purchaser. Provided that the Minimum Condition is satisfied
without being reduced or waived, Danaher will, following completion of the
Offer, own sufficient Shares to ensure that the required vote or written
consent of the stockholders will be obtained and that the Merger will be
consummated.

   If the Merger is consummated, stockholders of Lifschultz who elected not to
tender their Shares in the Offer will receive the same amount of consideration
in exchange for each Share (other than Dissenting Shares) as they would have
received in the Offer.

   If, following the consummation of the Offer, the Merger is not consummated,
Danaher, which indirectly owns 100% of the common stock of the Purchaser,
indirectly will control the number of Shares acquired by the Purchaser pursuant
to the Offer. Under the Merger Agreement, promptly following payment by the
Purchaser for Shares purchased pursuant to the Offer, and from time to time
thereafter, subject to applicable law and at the request of the Purchaser,
Lifschultz has agreed to take all actions necessary to cause a majority of the
directors of Lifschultz to consist of persons designated by Danaher (whether,
at the election of Lifschultz, by means of increasing the size of the board of
directors or seeking the resignation of directors and causing Danaher designees
to be elected). As a result of its ownership of such Shares and right to
designate nominees for election to the Lifschultz Board, Danaher, indirectly,
will be able to influence decisions of the Lifschultz Board and the decisions
of the Purchaser as a stockholder of Lifschultz. This concentration of
influence in one stockholder may adversely affect the market value of the
Shares.

   If Danaher controls more than 50% of the outstanding Shares following the
consummation of the Offer but the Merger is not consummated, stockholders of
Lifschultz, other than those affiliated with Danaher, will lack sufficient
voting power to elect directors or to cause other actions to be taken which
require majority approval. If for any reason following completion of the Offer
the Merger is not consummated, Danaher and the Purchaser reserve the right to
acquire additional Shares through private purchases, market transactions,
tender or exchange offers or otherwise on terms and at prices that may be more
or less favorable than those of the Offer or, subject to any applicable legal
restrictions, to dispose of any or all Shares acquired by them.

   (c) The Stockholders' Agreement. Concurrently with the execution of the
Merger Agreement, Danaher entered into the Stockholders' Agreement with David
K. Lifschultz, Sidney B. Lifschultz, Lawrence Lifschultz, David A. Berman, the
Sidney B. Lifschultz 1992 Family Trust, Michael Hirst and J. Randall Owen.
Together, the Principal Stockholders, as of May 15, 2001, owned or had voting
and investment control over 478,189 Shares, or approximately 42% of the
outstanding Shares. Under the terms of the Stockholders' Agreement, certain
Shares held by a corporation of which David Lifschultz is an officer and
director are not considered beneficially owned by Mr. Lifschultz for purposes
of the Stockholders' Agreement.

   Pursuant to the Stockholders' Agreement, each Principal Stockholder has
agreed to tender or cause to be tendered in the Offer all Shares owned of
record or beneficially by such Principal Stockholder. Each Principal
Stockholder has also agreed to vote or cause to be voted all Shares owned of
record or beneficially by such Principal Stockholder:

  .  in favor of the Merger and the Merger Agreement, and

                                       23


  .  unless otherwise requested by Danaher, against (1) any merger agreement,
     merger, consolidation, liquidation or winding up of, by or involving
     Lifschultz or any of its subsidiaries, (2) any Acquisition Transaction,
     and (3) any amendment or modification of the certificate of
     incorporation or bylaws of Lifschultz or any of its subsidiaries, or any
     other proposal or transaction involving Lifschultz or any of its
     subsidiaries which is reasonably likely to (A) prevent, impede, impair,
     frustrate or nullify the Offer, the Merger, the Merger Agreement or any
     of the other transactions contemplated by the Merger Agreement, or (B)
     change any of the voting rights of any class of capital stock or other
     securities of Lifschultz (collectively, the "Negative Voting Matters").

   Each Principal Stockholder also granted Danaher a proxy to vote the Shares
owned of record and beneficially by such Principal Stockholder:

  .  in favor of the Merger, the Merger Agreement and the transactions
     contemplated thereby,

  .  against any Negative Voting Matter or any other action or agreement that
     would result in a breach or inaccuracy by Lifschultz under the Merger
     Agreement, and

  .  in favor of any other matter necessary for the consummation of the Offer
     and the other transactions contemplated under the Merger Agreement or
     the Stockholders' Agreement.

   Each Principal Stockholder has also agreed not to transfer or otherwise
dispose of, or grant any other proxy with respect to, or change or agree to
change the beneficial ownership of, such Principal Stockholder's Shares. Each
Principal Stockholder has further agreed not to, and not to permit or authorize
his, her or its affiliates, representatives or agents to, directly or
indirectly, encourage, solicit, explore, participate in or initiate discussions
or negotiations with, or provide or disclose any information to, any
corporation, partnership, person or other entity or group (other than Danaher,
the Purchaser or any of their affiliates or representatives) concerning any
Acquisition Transaction or enter into any contract, arrangement or
understanding requiring Lifschultz to abandon, terminate or fail to consummate
the Merger or any other transactions contemplated by the Merger Agreement.

   The Stockholders' Agreement and the parties' obligations thereunder
terminate on the earlier of (1) payment for the Shares owned by the Principal
Stockholders pursuant to the Offer, or (2) termination of the Merger Agreement
as described under "Termination."

   (d) Consulting, Employment and Other Agreements. At the time Danaher entered
into the Merger Agreement, Fluke Electronics Corporation, an indirect, wholly-
owned subsidiary of Danaher and the direct parent of the Purchaser ("Fluke
Electronics"), entered into a consulting and a noncompetition agreement with
each of David K. Lifschultz, the Chairman and Chief Executive Officer of
Lifschultz, James C. Triplett, the Chairman and Chief Executive Officer of
Hart, and J. Randall Owen, the President and Chief Operating Officer of Hart.
Fluke Electronics also entered into a noncompetition agreement with Dennis
Hunter, President, Chief Financial Officer and Director of Lifschultz and
President and Chief Executive Officer of CSC. In addition, Lifschultz entered
into a termination agreement with Mr. Triplett in connection with certain
amounts owed to Mr. Triplett in connection with the proposed sale of
Lifschultz. The terms of each agreement will become effective on the Effective
Time of the Merger.

   Mr. Lifschultz's consulting agreement provides that he will provide
consulting services to Fluke Electronics for a period of one year terminating
on the first anniversary of the Effective Time, for purposes of assisting in
the implementation of Danaher's acquisition of Lifschultz. Mr. Lifschultz will
also be subject to covenants intended to bar his competition and his
solicitation of clients or employees for a period of three years following the
Effective Time. In addition, Mr. Lifschultz agreed to release Lifschultz,
including its subsidiaries and affiliates, from any claims he may have relating
to any matters existing at any time at or prior to the Effective Time. Danaher
will agree to a reciprocal release of Mr. Triplett as of the Effective Time.
Mr. Lifschultz also agreed to indemnify Fluke Electronics, Lifschultz and their
respective subsidiaries and affiliates

                                       24


from and against costs and expenses relating to certain judgments previously
rendered against Lifschultz Fast Freight, Inc. Mr. Lifschultz also consented to
having his outstanding options to purchase Shares cashed out at the Effective
Time, pursuant to the terms of the Merger Agreement. The terms of the
consulting agreement supersede, and render null and void, any agreements Mr.
Lifschultz may have had pertaining to his employment with Hart or to any
compensation owed to him relating to a change in control of Hart or Lifschultz.
Subject to the consummation of the Offer and Merger, and in consideration of
Mr. Lifschultz's obligations under the consulting agreement, Fluke Electronics
will pay Mr. Lifschultz a fee of $375,000, payable in two installments of
$187,500, the first of which is to be paid upon the Effective Time and the
second on January 1, 2002. Mr. Lifschultz's consulting agreement will
terminate, and no party thereto will have any obligations thereunder, upon
termination of the Offer or Merger Agreement.

   Mr. Triplett's consulting agreement provides he will remain employed with
Hart until the later of July 31, 2001 or the Effective Time. Thereafter, he
will provide a maximum of 1,040 hours of consulting services to Fluke
Electronics, for purposes of assisting in the implementation of Danaher's
acquisition of Lifschultz. Mr. Triplett will also be subject to covenants
intended to bar his competition and his solicitation of clients or employees
for a period of three years following the Effective Time. In addition, Mr.
Triplett agreed, as of the Effective Time, to release Lifschultz, Danaher and
Fluke, including their subsidiaries and affiliates, from any claims he may have
relating to any matters existing at any time at or prior to the Effective Time.
Danaher will agree to a reciprocal release of Mr. Triplett as of the Effective
Time. Mr. Triplett also consented to having his outstanding options to purchase
Shares cashed out at the Effective Time, pursuant to the terms of the Merger
Agreement. Except for severance payments owed to Mr. Triplett pursuant to the
termination of his employment agreement (as described below), certain medical
insurance rights and certain indemnification rights to which he is entitled
under his employment agreement, the terms of the consulting agreement
supersede, and render null and void, any agreements Mr. Triplett may have had
pertaining to his employment with Hart or to any compensation owed to him
relating to a change in control of Hart or Lifschultz. Subject to the
consummation of the Offer and Merger, and in consideration of Mr. Triplett's
obligations under the consulting agreement, Fluke Electronics will pay Mr.
Triplett a fee of $800,000, payable in four annual installments of $200,000,
beginning on August 1, 2002. Mr. Triplett's consulting agreement will
terminate, and no party thereto will have any obligations thereunder, upon
termination of the Offer or Merger Agreement.

   Pursuant to the Sale/Merger/Acquisition Agreement dated as of April 24, 2000
by and between Mr. Triplett and Lifschultz (the "Sale Agreement"), upon certain
acquisitions of Lifschultz, Mr. Triplett is entitled to an amount equal to 10%
of the excess amount paid for Lifschultz over $25,000,000, in consideration for
services provided by Triplett to Lifschultz in arranging, negotiating and
closing such transaction. Simultaneous with the execution of the Merger
Agreement, Lifschultz and Mr. Triplett entered into a termination agreement
which provides that, pursuant to the Sale Agreement, at the Effective Time
Lifschultz will pay or cause to be paid to Mr. Triplett an amount equal to
approximately $715,000, and that upon such payment all rights and obligations
under the Sale Agreement will terminate.

   Under the terms of the employment agreement dated as of August 25, 1997, by
and between Hart and Mr. Triplett, if the employment agreement is terminated by
Hart without cause, Mr. Triplett is entitled to a severance payment equal to
50% of the base compensation remaining to be paid to him over the term of the
employment agreement. On May 15, 2001, Mr. Triplett's employment agreement was
terminated without cause as of the Effective Time (provided that, to the extent
the Effective Time occurs prior to July 31, 2001, Mr. Triplett will remain as
an at-will employee of Hart), and Mr. Triplett will be entitled to a payment of
approximately $1,295,000 as a result of such termination.

   Mr. Owen's consulting agreement provides he will remain employed with Hart
until the later of July 31, 2001 or the Effective Time. Thereafter, he will
provide 600 hours of consulting services to Fluke Electronics for a period
terminating on the first anniversary of the date his employment with Hart is
terminated, for purposes of assisting in the implementation of Danaher's
acquisition of Lifschultz. Mr. Owen will also be subject to covenants intended
to bar his competition and his solicitation of clients or employees for a
period of

                                       25


three years following the Effective Time. In addition, Mr. Owen agreed, as of
the Effective Time, to release Lifschultz, Danaher and Fluke, including their
subsidiaries and affiliates, from any claims he may have relating to any
matters existing at any time at or prior to the Effective Time. Danaher will
agree to a reciprocal release of Mr. Owen as of the Effective Time. Mr. Owen
also consented to having his outstanding options to purchase Shares cashed out
at the Effective Time, pursuant to the terms of the Merger Agreement. The terms
of the consulting agreement supersede, and render null and void, any agreements
Mr. Owen may have had pertaining to his employment with Hart or to any
compensation owed to him relating to a change in control of Hart or Lifschultz.
Subject to the consummation of the Offer and Merger, and in consideration of
Mr. Owen's obligations under the consulting agreement, Fluke Electronics will
pay Mr. Owen a fee of $330,000 upon severance of his employment with Hart. Mr.
Owen's consulting agreement will terminate, and no party thereto will have any
obligations thereunder, upon termination of the Offer or Merger Agreement.

   Mr. Hunter's agreement provides that, in consideration for Mr. Hunter
waiving any rights or agreements he may have had pertaining to his employment
with Lifschultz or any affiliate or subsidiary thereof (except for severance
payments owed to Mr. Hunter pursuant to the termination of his employment
agreement (as described below) and except for certain debt in the amount of
$72,000 that Lifschultz owes to Mr. Hunter), or to any compensation owed to him
relating to a change in control of Lifschultz or any affiliate or subsidiary
thereof, Fluke Electronics will pay him a fee of $250,000 upon the Effective
Time of the Merger. Mr. Hunter will also be subject to covenants intended to
bar his competition and his solicitation of clients or employees for a period
of two years following the termination of his employment with Fluke Electronics
or any subsidiary or affiliate thereof. In addition, Mr. Hunter agreed to
release Lifschultz and Fluke Electronics, including their respective
subsidiaries and affiliates, from any claims he may have relating to any
matters existing at any time at or prior to the Effective Time. Mr. Hunter also
consented to having his outstanding options to purchase Shares cashed out at
the Effective Time, pursuant to the terms of the Merger Agreement. Mr. Hunter's
agreement will terminate, and no party thereto will have any obligations
thereunder, upon termination of the Offer or Merger Agreement.

   Under the terms of the employment agreement dated as of August 1, 1998, by
and between CSC and Mr. Hunter, if Mr. Hunter is terminated by CSC without
cause, Mr. Hunter is entitled to a severance payment equal to 50% of the base
compensation remaining to be paid to him over the term of the employment
agreement. On May 15, 2001, Mr. Hunter's employment agreement was terminated
without cause effective as of the Effective Time of the Merger, although Mr.
Hunter will be retained as of the Effective Time as an at-will employee. At the
Effective Time, Mr. Hunter will be entitled to a payment of approximately
$461,000 as a result of such termination.

   (e) Statutory Requirements. In general, under the GCL, a merger of two
Delaware corporations requires the adoption of a resolution by the board of
directors of each of the corporations desiring to merge approving an agreement
of merger containing provisions with respect to certain statutorily specified
matters, and the approval of such agreement of merger by the stockholders of
each corporation by the affirmative vote of the holders of a majority of all
the outstanding shares of stock entitled to vote on such merger. The Shares
entitle the holders thereof to voting rights.

   The GCL also provides that, if a parent company owns at least 90% of each
class of stock of a subsidiary, the parent company can effect a short-form
merger with that subsidiary without the action of the other stockholders of the
subsidiary. Accordingly, if, as a result of the Offer or otherwise the
Purchaser acquires or controls the voting power of at least 90% of the
outstanding Shares, the Purchaser could, and intends to, effect the Merger
without prior notice to, or any action by, any other stockholder of Lifschultz.

   (f) Appraisal Rights. No appraisal rights are available in connection with
the Offer. However, if the Merger is consummated, stockholders of Lifschultz
will have certain rights under Section 262 of the GCL to dissent and demand
appraisal of, and payment in cash of the fair value of, Dissenting Shares. Such
rights, if the statutory procedures were complied with, could lead to a
judicial determination of the fair value (excluding any element of value
arising from the accomplishment or expectation of the Merger) required to be
paid in cash to

                                       26


such dissenting holders for their Dissenting Shares. Any such judicial
determination of the fair value of Dissenting Shares could be based upon
considerations other than, or in addition to, the price per Share paid in the
Offer and the market value of the Dissenting Shares, including asset values and
the investment value of the Dissenting Shares. The value so determined could be
more or less than the price per Share pursuant to the Offer or the
consideration per Share to be paid in the Merger.

   In addition, several decisions by Delaware courts have held that, in certain
instances, a controlling stockholder of a corporation involved in a merger has
a fiduciary duty to the other stockholders that requires the merger to be fair
to such other stockholders. In determining whether a merger is fair to minority
stockholders, the Delaware courts have considered, among other things, the type
and amount of consideration to be received by the stockholders and whether
there were fair dealings among the parties. Although the remedies of rescission
or other damages are possible in an action challenging a merger as a breach of
fiduciary duty, decisions of the Delaware courts have indicated that in most
cases the remedy available in a merger that is found not to be "fair" to
minority stockholders is a damages remedy based on essentially the same
principles as an appraisal.

   The foregoing summary of the rights of objecting stockholders does not
purport to be a complete statement of the procedures to be followed by
stockholders desiring to exercise any available dissenters' rights.

   The preservation and exercise of dissenters' rights require strict adherence
to the applicable provisions of the GCL.

   (g) Plans for Lifschultz. In connection with the Offer, Danaher and the
Purchaser have reviewed and will continue to review various possible business
strategies that they might consider in the event that the Purchaser acquires
control of Lifschultz, whether pursuant to this Offer, the Merger or otherwise.
Such changes could include, among other things, changes in Lifschultz's
business, corporate structure, capitalization and management.

   (h) "Going Private" Transactions. The SEC has adopted Rule 13e-3 under the
Securities Exchange Act which is applicable to certain "going private"
transactions and which may, under certain circumstances, be applicable to the
Merger. However, Rule 13e-3 would be inapplicable if (a) the Shares are
deregistered under the Securities Exchange Act prior to the Merger or other
business combination or (b) the Merger or other business combination is
consummated within one year after the purchase of the Shares pursuant to the
Offer and the amount paid per Share in the Merger or other business combination
is at least equal to the amount paid per Share in the Offer. If applicable,
Rule 13e-3 requires, among other things, that certain financial information
concerning the fairness of the proposed transaction and the consideration
offered to minority stockholders in such transaction be filed with the SEC and
disclosed to stockholders prior to the consummation of the transaction.

12. Source and Amount of Funds.

   The Purchaser estimates that the total amount of funds required to purchase
all outstanding Shares pursuant to the Offer and to pay related fees and
expenses will be approximately $34 million, plus debt to be assumed. Danaher
will ensure that the Purchaser has sufficient funds to acquire all of the
outstanding Shares pursuant to the Offer and the Merger.

   Danaher has possession of sufficient funds to close the Offer and the
Merger, and will cause the Purchaser to have sufficient funds available to
close the Offer and the Merger.

13. Dividends and Distributions.

   The Merger Agreement provides that, without the prior written consent of
Danaher, Lifschultz will not, and will not permit any of its subsidiaries to,
prior to the Effective Time, (a) issue, reissue, sell, pledge, dispose

                                       27


of, grant or encumber, or authorize the issuance, reissuance, sale, pledge,
disposal, grant or encumbrance of (1) any shares of capital stock of any class
of Lifschultz or any of its subsidiaries, or securities convertible into any
such capital stock, or any rights, warrants or options to acquire any such
convertible securities or capital stock, or any other ownership interest in
Lifschultz or any of its subsidiaries, or (2) any other securities in respect
of, in lieu of, or in substitution for, Shares outstanding as of May 15, 2001,
(b) alter or make any other changes in its capital structure, (c) adopt, ratify
or effectuate a stockholders' rights plan or similar agreement, or (d) declare,
set aside or pay any dividend or other distribution (whether in cash,
securities or property or any combination thereof) in respect of any class or
series of its capital stock other than between Lifschultz and any of its
wholly-owned subsidiaries.

14. Conditions of the Offer.

   Notwithstanding any other provision of the Offer, the Purchaser shall not be
required to accept for payment or, subject to any applicable rules and
regulations of the SEC, including Rule 14e-1(c) promulgated under the Exchange
Act (relating to the Purchaser's obligation to pay for or return tendered
Shares promptly after termination or withdrawal of the Offer), pay for, and may
terminate or, except as set forth in the Merger Agreement, delay the acceptance
of any tendered Shares for payment or amend the Offer, if (A) there will not be
validly tendered and not properly withdrawn prior to the Expiration Date that
number of Shares which represents at least a majority of the total number of
Shares outstanding on a fully diluted basis on the date of purchase (the
"Minimum Condition"), (B) any applicable waiting period or approval under any
applicable domestic or foreign statutes or regulations will not have expired or
been terminated or obtained prior to the Expiration Date, (C) any consents from
third parties will not have been obtained, except for those the failure of
which to be obtained would not have a material adverse effect on Lifschultz, or
(D) at any time on or after May 15, 2001, and prior to the time of acceptance
for payment or payment for any Shares, any of the following events (each, an
"Event") will occur:

     (a) there will be any action taken, or any statute, rule, regulation,
  legislation, interpretation, judgment, order or injunction enacted,
  enforced, promulgated, amended, issued or deemed applicable to the Offer or
  the Merger, by any legislative body, court, government or governmental,
  administrative or regulatory authority or agency, domestic or foreign,
  that, in the reasonable judgment of Danaher, would be expected to, directly
  or indirectly: (1) make illegal or otherwise prohibit or materially delay
  consummation of the Offer, the Merger or the acceptance for payment of some
  or all of the Shares, or seek to obtain material damages or make materially
  more costly the making of the Offer, (2) prohibit or materially limit the
  ownership or operation by Danaher or the Purchaser of all or any material
  portion of the business or assets of Lifschultz or any of its subsidiaries
  taken as a whole or compel Danaher or the Purchaser to dispose of or hold
  separately all or any material portion of the business or assets of Danaher
  or the Purchaser or Lifschultz or any of its subsidiaries taken as a whole,
  or seek to impose any material limitation on the ability of Danaher or the
  Purchaser to conduct its business or own such assets, in any such case
  under this clause (2), which would have a material adverse effect on
  Danaher or Lifschultz, as the case may be, (3) impose material limitations
  on the ability of Danaher or the Purchaser effectively to acquire, hold or
  exercise full rights of ownership of the Shares, including, without
  limitation, the right to vote any Shares acquired or owned by the Purchaser
  or Danaher on all matters properly presented to the Lifschultz
  stockholders, or (4) require divestiture by Danaher or the Purchaser of any
  Shares; or

     (b) there will be instituted or pending any action or proceeding by any
  governmental entity seeking, or that would reasonably be expected to result
  in, any of the consequences referred to in clauses (1) through (4) of
  paragraph (a) above or by any third party for which there is a substantial
  likelihood of resulting in any of the consequences referred to in clauses
  (1) through (4) of paragraph (a) above; or

     (c) any change will have occurred (or any development will have occurred
  involving prospective changes) in the business, assets, liabilities,
  condition (financial or otherwise), prospects or results of operations of
  Lifschultz or any of its subsidiaries that has, or could reasonably be
  expected to have, a material adverse effect on Lifschultz; or

                                       28


     (d) (1) the Lifschultz Board or any committee of the Lifschultz Board
  will have withheld, withdrawn, failed to reaffirm at the request of
  Danaher, or will have modified or amended in a manner adverse to Danaher or
  the Purchaser, the approval, adoption or recommendation, as the case may
  be, of the Offer, the Merger or the Merger Agreement, or will have approved
  or recommended any Acquisition Transaction, (2) a person will have entered
  into an agreement, agreement in principle or any other contract with
  Lifschultz with respect to an Acquisition Transaction, or (3) the
  Lifschultz Board or any committee of the Lifschultz Board will have
  resolved to do or enter into any of the foregoing; or

     (e) Lifschultz, the Purchaser and Danaher will have reached an agreement
  that the Offer or the Merger Agreement be terminated, or the Merger
  Agreement will have been terminated in accordance with its terms; or

     (f) any of the representations and warranties of Lifschultz set forth in
  the Merger Agreement, when read without any exception or qualification as
  to materiality or material adverse effect on Lifschultz, will not be true
  and correct, as if those representations and warranties were made at the
  time of such determination (except as to any such representation or
  warranty which speaks as of a specific date, which must be untrue or
  incorrect as of that specific date) except where the failure to be so true
  and correct would not, individually or in the aggregate, reasonably be
  expected to (1) have a material adverse effect on Lifschultz, (2) prevent
  or materially delay the consummation of the Offer, (3) materially increase
  the cost of the Offer to the Purchaser or (4) have a material adverse
  effect on the benefits to Danaher of the transactions contemplated by the
  Merger Agreement; or

     (g) Lifschultz will have failed to perform in any material respect or to
  comply in any material respect with any of its material obligations,
  covenants or agreements under the Merger Agreement; provided that any
  breach of Section 6.1(r) would constitute a material failure to perform by
  Lifschultz; or

     (h) there will have occurred, and continue to exist, (1) any general
  suspension of, or limitation on prices for, trading in securities on the
  New York Stock Exchange or on the over-the-counter stock market, as
  reported by the National Association of Securities Dealers, Inc. Automated
  Quotations System, (2) any decline of at least 20% in either the Dow Jones
  Average of Industrial Stocks or the Standard & Poor's 500 Index from the
  close of business on the last trading day immediately preceding the date of
  the Merger Agreement through the applicable Expiration Date, (3) a
  declaration of a banking moratorium or any suspension of payments in
  respect of banks in the United States, or (4) a commencement of a war,
  armed hostilities or other national or international crisis involving the
  United States or a material limitation (whether or not mandatory) by any
  governmental entity on the extension of credit by banks or other lending
  institutions; or

     (i) (1) any of the agreements described on Schedule 6.1(r) to the Merger
  Agreement shall not have been executed by the applicable officer or
  director of Lifschultz or one of its subsidiaries, or shall no longer be in
  full force and effect, (2) Mr. Triplett or Mr. Owen shall not have executed
  a release in the respective form attached as Exhibit A to such person's
  consulting and noncompetition agreement, (3) any of the directors of
  Lifschultz, and, to the extent requested by Purchaser, of any or all of
  Lifschultz's subsidiaries, shall not have submitted a letter of resignation
  effective as of the Effective Time, or (4) any holder of any outstanding
  options to purchase Lifschultz common stock shall have failed to execute a
  Stock Option Termination Agreement in the form attached as Exhibit B to the
  Merger Agreement.

   The foregoing conditions (including those set forth in clauses (A), (B) and
(C) of the initial paragraph) are for the sole benefit of Danaher and the
Purchaser and may be asserted by Danaher or the Purchaser regardless of the
circumstances (including any action or inaction by Danaher or the Purchaser)
giving rise to any such conditions and may be waived by Danaher or the
Purchaser in whole or in part at any time and from time to time, in each case,
in the exercise of the sole discretion of Danaher and the Purchaser and subject
to the terms of the Merger Agreement. The failure by Danaher or the Purchaser
at any time to exercise any of the foregoing rights shall not be deemed a
waiver of any such right and each such right shall be deemed an ongoing right
which may be asserted at any time and from time to time.


                                       29


   A public announcement may be made of a material change in, or waiver of,
such conditions and the Offer may, in certain circumstances, be extended in
connection with any such change or waiver.

15. Legal Matters; Required Regulatory Approvals.

   Except as set forth in this Offer to Purchase, based on our review of
publicly available filings by Lifschultz with the SEC and other information
regarding Lifschultz, we are not aware of any licenses or regulatory permits
that appear to be material to the business of Lifschultz and its subsidiaries,
taken as a whole, and that might be adversely affected by our acquisition of
Shares in the Offer. In addition, we are not aware of any filings, approvals or
other actions by or with any governmental authority or administrative or
regulatory agency that would be required for our acquisition or ownership of
the Shares. Should any such approval or other action be required, we expect to
seek such approval or action, except as described under "State Takeover Laws."
Should any such approval or other action be required, we cannot be certain that
we would be able to obtain any such approval or action without substantial
conditions or that adverse consequences might not result to Lifschultz's or its
subsidiaries' businesses, or that certain parts of Lifschultz's, Danaher's, the
Purchaser's or any of their respective subsidiaries' businesses might not have
to be disposed of or held separate in order to obtain such approval or action.
In that event, we may not be required to purchase any Shares in the Offer. See
Introduction and Section 14 for a description of the conditions to the Offer.

   State Takeover Laws. A number of states (including Delaware, where
Lifschultz is incorporated) have adopted takeover laws and regulations that
purport to be applicable to attempts to acquire securities of corporations that
are incorporated in those states or that have substantial assets, stockholders,
principal executive offices or principal places of business in those states. To
the extent that these state takeover statutes purport to apply to the Offer or
the Merger, we believe that those laws conflict with U.S. federal law and are
an unconstitutional burden on interstate commerce. In 1982, the Supreme Court
of the United States, in Edgar v. Mite Corp., invalidated on constitutional
grounds the Illinois Business Takeovers Statute, which as a matter of state
securities law made takeovers of corporations meeting certain requirements more
difficult. The reasoning in that decision is likely to apply to certain other
state takeover statutes. In 1987, however, in CTS Corp. v. Dynamics Corp. of
America, the Supreme Court of the United States held that the State of Indiana
could as a matter of corporate law and, in particular, those aspects of
corporate law concerning corporate governance, constitutionally disqualify a
potential acquiror from voting on the affairs of a target corporation without
the prior approval of the remaining stockholders, as long as those laws were
applicable only under certain conditions. Subsequently, in TLX Acquisition
Corp. v. Telex Corp., a federal district court in Oklahoma ruled that the
Oklahoma statutes were unconstitutional insofar as they apply to corporations
incorporated outside Oklahoma, because they would subject those corporations to
inconsistent regulations. Similarly, in Tyson Foods, Inc. v. McReynolds, a
federal district court in Tennessee ruled that four Tennessee takeover statutes
were unconstitutional as applied to corporations incorporated outside
Tennessee. This decision was affirmed by the United States Court of Appeals for
the Sixth Circuit. In December 1988, a federal district court in Florida held,
in Grand Metropolitan PLC v. Butterworth, that the provisions of the Florida
Affiliated Transactions Act and the Florida Control Share Acquisition Act were
unconstitutional as applied to corporations incorporated outside of Florida.

   We have not attempted to comply with any state takeover statutes in
connection with the Offer or the Merger. We reserve the right to challenge the
validity or applicability of any state law allegedly applicable to the Offer or
the Merger, and nothing in this Offer to Purchase nor any action that we take
in connection with the Offer is intended as a waiver of that right. In the
event that it is asserted that one or more takeover statutes apply to the Offer
or the Merger, and it is not determined by an appropriate court that the
statutes in question do not apply or are invalid as applied to the Offer or the
Merger, as applicable, we may be required to file certain documents with, or
receive approvals from, the relevant state authorities, and we might be unable
to accept for payment or purchase Shares tendered in the Offer or be delayed in
continuing or consummating the Offer. In that case, we may not be obligated to
accept for purchase, or pay for, any Shares tendered. See Section 14.


                                       30


   Antitrust. Under the Hart-Scott-Rodino Antitrust Improvements Act of 1976,
as amended, and the related rules and regulations that have been issued by the
U.S. Federal Trade Commission (the "FTC"), certain acquisition transactions may
not be consummated until certain information and documentary material has been
furnished for review by the FTC and the Antitrust Division of the U.S.
Department of Justice (the "Antitrust Division") and certain waiting period
requirements have been satisfied. These requirements do not apply to our
acquisition of Shares in the Offer and the Merger.

   The FTC and the Antitrust Division frequently scrutinize the legality under
the antitrust laws of transactions, such as our acquisition of Shares in the
Offer and the Merger. At any time before or after our purchase of Shares, the
FTC or the Antitrust Division could take any action under the antitrust laws
that either considers necessary or desirable in the public interest, including
seeking to enjoin the purchase of Shares in the Offer and the Merger, the
divestiture of Shares purchased in the Offer or the divestiture of substantial
assets of Danaher, the Purchaser, Lifschultz or any of their respective
subsidiaries or affiliates. Private parties as well as state attorneys general
may also bring legal actions under the antitrust laws under certain
circumstances.

   Based upon an examination of publicly available information relating to the
businesses in which Lifschultz is engaged, we believe that the acquisition of
Shares in the Offer and the Merger should not violate the applicable antitrust
laws. Nevertheless, we cannot be certain that a challenge to the Offer and the
Merger on antitrust grounds will not be made, or, if such challenge is made,
what the result will be.

   Other Foreign Approvals. According to publicly available information,
Lifschultz conducts business in a number of foreign countries and
jurisdictions. In connection with the acquisition of the Shares in the Offer or
the Merger, the laws of certain of those foreign countries and jurisdictions
may require the filing of information with, or the obtaining of the approval or
consent of, governmental authorities in such countries and jurisdictions. The
governments in those countries and jurisdictions might attempt to impose
additional conditions on the Surviving Corporation's operations conducted in
those countries and jurisdictions as a result of the acquisition of the Shares
in the Offer or the Merger. If such approvals or consents are found to be
required the parties intend to make the appropriate filings and applications.
In the event such a filing or application is made for the requisite foreign
approvals or consents, we cannot be certain that such approvals or consents
will be granted and, if such approvals or consents are received, we cannot be
certain as to the date of those approvals or consents. In addition, we cannot
be certain that we will be able to cause Lifschultz or its subsidiaries to
satisfy or comply with those laws or that compliance or noncompliance will not
have adverse consequences for Lifschultz or any subsidiary after purchase of
the Shares pursuant to the Offer or the Merger.

16. Fees and Expenses.

   We have retained D.F. King & Co., Inc. as Information Agent in connection
with the Offer. The Information Agent may contact holders of Shares by mail,
telephone, telex, telegraph and personal interview and may request brokers,
banks, agents, dealers and other nominee stockholders to forward material
relating to the Offer to beneficial owners of Shares. We will pay the
Information Agent reasonable and customary compensation for these services in
addition to reimbursing the Information Agent for its reasonable out-of-pocket
expenses. We have agreed to indemnify the Information Agent against certain
liabilities and expenses in connection with the Offer, including certain
liabilities under the U.S. federal securities laws.

   In addition, we have retained SunTrust Bank as the Depositary. We will pay
the Depositary reasonable and customary compensation for its services in
connection with the Offer, will reimburse the Depositary for its reasonable
out-of-pocket expenses and will indemnify the Depositary against certain
liabilities and expenses, including certain liabilities under the U.S. federal
securities laws.

   Except as set forth above, we will not pay any fees or commissions to any
broker, dealer or other person for soliciting tenders of Shares pursuant to the
Offer. We will reimburse brokers, dealers, commercial banks and trust companies
and other nominees, upon request, for customary clerical and mailing expenses
incurred by them in forwarding offering materials to their customers.

                                       31


17. Miscellaneous.

   We are not aware of any jurisdiction where the making of the Offer is
prohibited by any applicable law. If we become aware of any valid state statute
prohibiting the making of the Offer or the acceptance of the Shares pursuant
thereto, we will make a good faith effort to comply with that state statute or
seek to have such statute declared in applicable to the Offer. If, after a good
faith effort, we cannot comply with the state statute, we will not make the
Offer to, nor will we accept tenders from or on behalf of, the holders of
Shares in that state.

   We have filed with the SEC a Schedule TO, together with exhibits, furnishing
certain additional information with respect to the Offer, and may file
amendments to our Schedule TO. Our Schedule TO and any exhibits or amendments
may be examined and copies may be obtained from the SEC in the same manner as
described in Section 8 with respect to information concerning Lifschultz,
except that copies will not be available at the regional offices of the SEC.

   We have not authorized any person to give any information or to make any
representation on our behalf not contained in this Offer to Purchase or in the
Letter of Transmittal and, if given or made, you should not rely on any such
information or representation as having been authorized.

   Neither the delivery of the Offer to Purchase nor any purchase pursuant to
the Offer will under any circumstances create any implication that there has
been no change in the affairs of Danaher, the Purchaser, Lifschultz or any of
their respective subsidiaries since the date as of which information is
furnished or the date of this Offer to Purchase.
