                               DECEMBER   , 1996
 
Dear Fellow Shareholders:
 
     On November   , 1996, Laser Science, Inc. ("LSI") entered into an Agreement
and Plan of Merger (the "Merger Agreement") with Thermo Optek Corporation
("Thermo") and LSI Acquisition Corp., a wholly owned subsidiary of Thermo
("Acquisition"), pursuant to which Acquisition will merge (the "Merger") with
and into LSI and LSI will become a wholly owned subsidiary of Thermo. Upon
consummation of the Merger, shares of Thermo common stock would be issued to LSI
shareholders in exchange for all of the issued and outstanding shares of LSI
common stock outstanding on the effective date of the Merger (the "Effective
Date"). (The Effective Date, assuming the Merger is consummated, is expected to
be December 27, 1996.) The assumed value of each share of Thermo common stock to
be issued in the Merger will be determined based on the average closing price
for such stock on the American Stock Exchange during the 20 trading days prior
to the Effective Date (the "Average Price"). The total number of shares of
Thermo common stock to be issued in the Merger will be equal to the quotient
derived by dividing $3,400,000 by the Average Price. Currently, there are
1,325,605 shares of LSI common stock outstanding on a fully diluted basis (that
is, assuming the conversion of all shares of LSI Series 1 Preferred Stock into
LSI common stock and the exercise of all options and warrants to purchase shares
of LSI common or preferred stock). Thus, for example, based on the average
closing price of the Thermo common stock on the American Stock Exchange during
the 20 trading days ended on November 15, 1996, $12.36875, upon consummation of
the Merger, LSI shareholders would receive in exchange for each share of LSI
common stock owned on the Effective Date .2074 shares of Thermo common stock.
HOWEVER, THE AVERAGE CLOSING PRICE FOR THE THERMO COMMON STOCK DURING THE 20
TRADING DAYS PRIOR TO THE ACTUAL EFFECTIVE DATE MAY BE MORE OR LESS THAN
$12.36875. FURTHER, THE MERGER AGREEMENT PROVIDES THAT, IF THE AVERAGE PRICE IS
LESS THAN $10.97, THERMO MAY ELECT NOT TO CONSUMMATE THE MERGER. IN SUCH CASE,
THERMO WOULD BE RESPONSIBLE FOR THE PAYMENT OF LSI'S FEES AND EXPENSES INCURRED
IN CONTEMPLATION OF THE MERGER UP TO A MAXIMUM OF $  . Twenty percent of the
shares of Thermo common stock you would be entitled to receive in the Merger
will be held in escrow to provide collateral for indemnification to Thermo
against damages incurred as a result of any misrepresentations, breaches of
warranties and breaches of covenants in connection with the Merger. HOWEVER, THE
ACTUAL AMOUNT OF DAMAGES TO THERMO FOR CERTAIN MISREPRESENTATIONS OR BREACHES
FOR WHICH THE LSI SHAREHOLDERS MAY BE HELD RESPONSIBLE PURSUANT TO THE MERGER
AGREEMENT MAY BE MORE THAN THE VALUE OF SUCH ESCROWED SHARES. See "The Merger --
Indemnification of Thermo; Escrow."
 
     LSI MANAGEMENT BELIEVES THE MERGER AND THE RELATED TRANSACTIONS ARE IN THE
BEST INTERESTS OF LSI AND ITS SHAREHOLDERS. For information concerning
Management's reasons for making this recommendation, please read carefully the
sections in the enclosed Information Statement/Prospectus entitled "The Merger."
 
     In accordance with the Restated Certificate of Incorporation of LSI and the
General Corporation Law of the State of Delaware, the Merger and the Merger
Agreement may be approved and adopted without a stockholders' meeting by the
written consent of the holders of shares holding the requisite percentage of
votes entitled to be cast thereon. As a result, management will be requesting
that LSI stockholders who elect to do so approve and adopt the Merger and the
Merger Agreement by executing written consents thereto. In the event that
written consents of the holders of shares holding the requisite percentage of
votes entitled to be cast thereon are obtained, no further action will be
required by the stockholders under Delaware law to approve the transactions
contemplated by the Merger Agreement.
 
     The accompanying Information Statement/Prospectus explains in detail the
terms of the Merger and the Thermo common stock to be issued in the Merger. It
also contains financial information concerning LSI and Thermo. Please read the
Information Statement/Prospectus carefully.
 
     Stockholders who do not consent to the Merger Agreement are entitled to
appraisal rights, if the Merger is completed, as described in the Information
Statement/Prospectus. To exercise such appraisal rights, stockholders must take
certain actions within the time limits prescribed by Delaware law. The
Information Statement/Prospectus describes the actions stockholders must take
and other relevant considerations to the exercise of such rights.
 
                                            Yours very truly,
 
                                            KENNETH J. GREENBERG

                                    SUMMARY
 
     The following is a summary of certain information contained in this
Information Statement/Prospectus concerning the proposed merger (the "Merger")
of LSI Acquisition Corp., a Delaware corporation ("Acquisition Corp.") which is
a wholly owned subsidiary of Thermo Optek Corporation, a Delaware corporation
("Thermo"), with and into Laser Science, Inc., a Delaware corporation ("LSI").
Acquisition Corp. has been formed specifically for the purpose of carrying out
the Merger. Thermo, Acquisition Corp. and LSI have entered into an Agreement and
Plan of Merger dated November   , 1996 (the "Merger Agreement"), which must be
approved by the shareholders of LSI. If so approved, the effective date of the
Merger is expected to be December 27, 1996. This summary should be read in
conjunction with, and is qualified in its entirety by reference to, the full
text of this Information Statement/Prospectus, including the exhibits hereto.
Each shareholder is, therefore, urged to read the entire Information
Statement/Prospectus with care.
 
THE COMPANIES
 
  Thermo and Acquisition Corp.
 
     Thermo develops, manufactures and markets analytical instruments that
utilize a range of optical spectroscopy techniques. These instruments are used
in the quantitative and qualitative chemical analysis of elements and molecular
compounds in a wide variety of solids, liquids and gases. Thermo is a
majority-owned subsidiary of Thermo Instrument Systems Inc. ("Thermo
Instrument"), which is a majority-owned subsidiary of Thermo Electron
Corporation ("Thermo Electron").
 
     Thermo was incorporated in Delaware in August 1995 as a wholly owned
subsidiary of Thermo Instrument. Thermo's name reflects its focus, which is the
development, manufacture and marketing of optical spectroscopy technologies and
instruments. After the formation of Thermo, Thermo Instrument transferred to
Thermo all of the assets, liabilities and businesses of Nicolet Instrument
Corporation ("Nicolet"), which conducts Thermo's FT-IR and FT-Raman spectrometer
businesses, and Thermo Jarrell Ash Corporation ("TJA"), which conducts Thermo's
atomic absorption ("AA") and atomic emission ("AE") spectrometer businesses.
Nicolet was acquired by Thermo Instrument in 1992. Through its subsidiary,
Thermo Vision Corporation ("Thermo Vision"), Thermo pursues applications of its
technologies for cost-effective, application-specific instruments and other
opportunities based on optical technologies. In September 1996, Thermo announced
its intent to spinout Thermo Vision through a distribution of all of its
outstanding capital stock in the form of a dividend to Thermo's shareholders.
See "Business -- Lines of Business -- Thermo Vision Corporation."
 
     Thermo has recently completed several acquisitions. In January 1995, Thermo
acquired the analytical instruments division of Baird, a manufacturer of
arc/spark spectrometers ("Baird"). In February 1996, Thermo Vision acquired both
Corion Corporation ("Corion"), a manufacturer of commercial optical filters, and
Oriel Corporation ("Oriel"), a manufacturer and distributor of electro-optical
instruments and components. In April 1996, Thermo acquired Mattson Instruments,
a manufacturer of FT-IR spectroscopy instruments ("Mattson"), and Unicam, a
manufacturer of AA and ultraviolet/visible spectroscopy instruments, from Thermo
Instrument ("Unicam"). Both of these businesses were formerly part of the
analytical instruments division of Analytical Technology, Inc. ("ATI") which
Thermo Instrument acquired in December 1995. Most recently, in November 1996,
Thermo acquired A.R.L. Applied Research Laboratories S.A. ("ARL"), a
manufacturer of arc/spark instruments used in elemental solids analysis and
wavelength dispersive x-ray fluorescence instruments, and VG Elemental ("VG
Elemental"), a manufacturer of inductively coupled plasma/mass spectrometers,
and four associated sales organizations located in South Africa, Austria, Sweden
and Canada, from Thermo Instrument. These businesses were formerly part of the
scientific instruments division of Fisons plc, portions of which were acquired
by Thermo Instrument in March 1996. See "Business of Thermo -- Acquisitions."
 
     Acquisition Corp. was formed specifically for the purpose of effecting the
transactions contemplated by the Merger Agreement. It is not anticipated that,
prior to the Merger, Acquisition Corp. will have any significant assets or
liabilities other than its rights and obligations under the Merger Agreement, or
that Acquisition Corp. will engage in any activities other than those incidental
to its formation and the transactions contemplated by the Merger Agreement.

  LSI
 
     LSI designs, manufactures and markets pulsed nitrogen laser technology and
pulsed CO(2) lasers. These products have applications in industry, medicine,
education and defense.
 
     The principal executive offices of LSI are located at 75 Chapel Street,
Newton, Massachusetts 02158 (telephone number: (617) 969-2211). See "Available
Information" and "Business of LSI".
 
THE MERGER
 
     Effective Time.  The Merger shall become effective upon the date of filing
of the Merger Agreement, together with certain officers' certificates, or a
Certificate of Merger, with the Secretary of State of the State of Delaware
pursuant to Section 103 of the Delaware General Corporation Law (the "Delaware
Law") or such other time as may be provided in the Merger Agreement (the
"Effective Time"). It is anticipated that the Effective Time will occur on
December 27, 1996.
 
     Required Vote.  According to the LSI Restated Certificate of Incorporation,
approval of the Merger Agreement requires the affirmative vote of the holders of
(i) at least a majority of the outstanding shares of the common stock of LSI
("LSI Common Stock") and LSI Series 1 Preferred Stock (the "LSI Series 1
Preferred Stock" and, together with the LSI Common Stock, the "LSI Capital
Stock") (assuming conversion of the shares of LSI Series 1 Preferred Stock into
shares of LSI Common Stock at the then applicable conversion price as provided
in LSI's Restated Certificate of Incorporation), voting together as a single
class; and (ii) at least sixty-six and two-thirds percent (66-2/3%) of the
outstanding shares of LSI Series 1 Preferred Stock. In accordance with the LSI
Restated Certificate of Incorporation and Delaware Law, the Merger and the
Merger Agreement may be approved and adopted without a stockholders meeting by
the written consent of the holders of shares of LSI Capital Stock holding the
requisite percentage of the votes entitled to be cast thereon. As a result,
management of LSI will be requesting that LSI stockholders who elect to do so
approve and adopt the Merger and the Merger Agreement by executing written
consents thereto. In the event that written consents of the holders of shares of
LSI Capital Stock holding the requisite percentage of votes entitled to be cast
thereon are obtained, no further action will be required by the stockholders
under Delaware Law to approve the Merger and the Merger Agreement. See "The
Merger -- Required Vote."
 
     As of November 20, 1996, the directors and officers of LSI beneficially
owned approximately 80% and 87% of the outstanding shares of LSI Common Stock
and LSI Series 1 Preferred Stock, respectively. See "Ownership of LSI Common
Stock and LSI Series 1 Preferred Stock."
 
     Exchange of Shares; Fractional Shares.  Upon consummation of the Merger,
each outstanding share of LSI Common Stock (other than shares held in LSI's
treasury and shares with respect to which statutory dissenters' rights are
perfected) will be converted into the right to receive a fraction of a share of
Thermo common stock, $.01 par value (the "Thermo Common Stock"), and Thermo will
become the owner of all of the issued and outstanding shares of LSI Capital
Stock. The assumed value of each share of Thermo Common Stock to be issued in
the Merger will be determined based on the average closing price for such stock
on the American Stock Exchange during the 20 trading days prior to the date on
which the Effective Time occurs (the "Average Price"). Assuming (i) no
shareholders exercise appraisal rights, (ii) all options and warrants to
purchase LSI Common Stock are exercised prior to the Effective Time, (iii) all
shares of LSI Series 1 Preferred Stock are converted into shares of LSI Common
Stock prior to the Effective Time, and (iv) an Average Price of $12.36875 (the
average closing price of the Thermo Common Stock on the American Stock
Exchange during the 20 trading days ended on November 15, 1996), based on the
number of outstanding shares of LSI Capital Stock, a total of approximately
274,930 shares of Thermo Common Stock would be issued to former LSI shareholders
upon the consummation of the Merger. As a result, a total of approximately
48,724,930 shares of Thermo Common Stock would then be outstanding, of which
approximately
 
                                        6
<PAGE>   10
 
274,930 shares, representing approximately 0.56% of the total, would be held by
former holders of LSI Capital Stock. HOWEVER, THE AVERAGE CLOSING PRICE FOR THE
THERMO COMMON STOCK DURING THE 20 TRADING DAYS PRIOR TO DECEMBER 27, 1996 (THE
DATE ON WHICH THE EFFECTIVE TIME IS EXPECTED TO OCCUR) MAY BE MORE OR LESS THAN
$12.36875. FURTHER, THE MERGER AGREEMENT PROVIDES THAT, IF THE AVERAGE PRICE IS
LESS THAN $10.97, THERMO MAY ELECT NOT TO CONSUMMATE THE MERGER. IN SUCH CASE,
THERMO WOULD BE RESPONSIBLE FOR THE PAYMENT OF LSI'S FEES AND EXPENSES INCURRED
IN CONTEMPLATION OF THE MERGER UP TO A MAXIMUM OF $  .
 
     No fractional shares of Thermo Common Stock will be issued in connection
with the Merger. Any LSI shareholder otherwise entitled to a fractional share of
Thermo Common Stock as a result of the Merger shall receive cash in lieu
thereof, without interest, in an amount determined by multiplying such LSI
shareholder's fractional interest by the closing price of Thermo Common Stock as
reported on the American Stock Exchange on the trading day immediately preceding
the date on which the Effective Time occurs. See "The Merger -- Procedure for
Exchange of Shares; Fractional Shares."
 
     Treatment of LSI Stock Options.  It is a condition to Thermo's obligation
to consummate the Merger that, prior to the Effective Time, all outstanding
options to purchase LSI Capital Stock ("LSI Options") shall have been exercised
in accordance with their terms or canceled and terminated (at no cost to LSI)
with the consent of the holders thereof. In connection with this condition, as
part of the LSI shareholders' written consent to the Merger, LSI management
intends to seek the approval of the LSI shareholders to an amendment to LSI's
1993 Stock Option Plan (the "LSI Option Plan") that would accelerate the vesting
of all LSI Options so that they are immediately exercisable prior to the
Effective Time. See "The Merger -- Treatment of LSI Stock Options" and "The
Merger -- Conditions to Consummation of the Merger."
 
     Treatment of LSI Warrants.  It is a condition to Thermo's obligation to
consummate the Merger that, prior to the Effective Time, all outstanding
warrants to purchase shares of LSI Common Stock or LSI Series 1 Preferred Stock
("LSI Warrants") shall have been exercised in accordance with their terms or
canceled and terminated (at no cost to LSI) with the consent of the holders
thereof. See "The Merger -- Conditions to Consummation of the Merger."
 
     Indemnification of Thermo; Escrow.  Twenty percent of the shares of Thermo
Common Stock issued in the Merger will be delivered into escrow (the "Indemnity
Escrowed Shares") and held pursuant to the Indemnification and Stock Escrow
Agreement attached as Exhibit A to the Merger Agreement (the "Escrow
Agreement"). The Indemnity Escrowed Shares will be reserved to provide
collateral for indemnification to Thermo against damages incurred as a result of
misrepresentations, breaches of warranties and breaches of covenants contained
in the Merger Agreement, the Escrow Agreement and any other agreements executed
in connection therewith, and to satisfy claims of Thermo arising as a result of
the Merger Agreement, the Escrow Agreement and such other agreements. See
Article VI of the Merger Agreement and Section 4 of the Escrow Agreement for a
description of the representations and warranties that are covered by the Escrow
Agreement. In the event Thermo has an appropriate claim for indemnification,
shares of Thermo Common Stock will be returned to Thermo in satisfaction of the
claim. The Escrow Agreement requires the escrow agent to deliver to the
shareholders the Indemnity Escrowed Shares remaining in escrow eighteen months
after the Effective Time, except that if there is a claim by Thermo at or prior
to such date, the escrow agent will retain Indemnity Escrowed Shares in an
amount sufficient to cover such claims until they are resolved. See "The Merger
- -- Indemnification of Thermo; Escrow."
 
     Conditions to the Merger.  The consummation of the Merger is conditioned
upon, among other things, (i) approval of the Merger and the adoption of the
Merger Agreement as required by Delaware Law, and by the holders of at least 95%
of the outstanding shares of each of the LSI Common Stock and the LSI Series 1
Preferred Stock, and (ii) the representations and warranties of each party to
the Merger Agreement being true and correct as of the Effective Time. The Merger
Agreement may be terminated by, among other things, the mutual consent of each
of Thermo and LSI. Any of the conditions to the Merger may be waived at any time
prior to the Merger by the party or parties to the Merger Agreement benefiting
from such conditions. However, no assurance can be given that any of such
parties will determine to waive any unfulfilled conditions. See "The Merger --
Conditions to Consummation of the Merger."

<PAGE>   11
 
     Certain Effects of the Merger.  If the Merger is consummated, the holders
of LSI Capital Stock (other than holders of shares with respect to which
dissenters' rights are perfected) will exchange their shares of stock for Thermo
Common Stock. The rights of LSI shareholders, which are presently governed by
Delaware Law and by the Restated Certificate of Incorporation and the By-Laws of
LSI, will be governed after the Merger by Delaware Law and the Certificate of
Incorporation and By-Laws of Thermo. Certain differences in the rights of LSI
shareholders will arise as a result of distinctions between the treatment of
public companies and private companies under Delaware Law, as well as
distinctions between the Restated Certificate of Incorporation and By-Laws of
LSI and the Certificate of Incorporation and By-Laws of Thermo. See "The Merger
- -- Certain Effects of the Merger" and "Comparison of Rights of Holders of Thermo
Common Stock and LSI Capital Stock."
 
     Interests of Certain Persons in the Merger.  Upon consummation of the
Merger, LSI's Board of Directors will resign, and Thermo will appoint new
directors as the sole members of LSI's Board of Directors. Certain officers of
LSI will retain their offices after the Effective Time, but Thermo may also
appoint additional officers of LSI. In addition, it is expected that, at the
Effective Time, Thermo and Kenneth Greenberg, President of LSI, will enter into
an agreement pursuant to which Thermo will guarantee the payment of Mr.
Greenberg's salary for one year following the date on which the Effective Time
occurs, subject to certain exceptions. See "The Merger -- Interests of Certain
Persons in the Merger," "Thermo and LSI Management and Executive Compensation --
Executive Officers and Directors of LSI."
 
RIGHTS OF DISSENTING SHAREHOLDERS
 
     Under Delaware Law, if the Merger is completed, holders of record of LSI
Capital Stock who properly exercise and perfect stockholder appraisal rights
with respect to the Merger have the right to have the "fair value" of their
shares (excluding any element of value arising from the accomplishment or
expectation of the Merger) determined by the Delaware Chancery Court. In order
to exercise such rights, holders must comply with the procedural requirements of
Section 262 of the Delaware Law, a description of which is provided under "The
Merger -- Rights of Dissenting Shareholders" and the full text of which is
attached to this Information Statement/Prospectus as Appendix B. Failure to take
any of the steps required under Section 262 on a timely basis may result in the
loss of appraisal rights. See "The Merger -- Rights of Dissenting Shareholders."
 
MARKET PRICES
 
     The high, low and closing prices of Thermo's Common Stock on the American
Stock Exchange on November 21, 1996, the date preceding the initial filing of
the Registration Statement of which this Information Statement/Prospectus forms
a part with the Securities and Exchange Commission (which filing constituted the
public announcement of the proposed Merger), were $12.25, $12.25 and $12.25,
respectively. The high, low and closing prices of Thermo's Common Stock on the
American Stock Exchange on December   , 1996 were $       , $       and
$       , respectively. Shareholders of LSI are urged to obtain current
quotations for the Thermo Common Stock.
 
     None of the LSI Capital Stock is currently, or has previously been, traded
on any established public market. Price quotations for LSI Capital Stock are,
therefore, not available.
 
     As of the date of this Information Statement/Prospectus, there were 1,344
record holders of Thermo Common Stock, 17 record holders of LSI Common Stock, 17
record holders of LSI Series 1 Preferred Stock and 34 holders of options and
warrants to purchase LSI Capital Stock.
 
OWNERSHIP OF SECURITIES
 
     As of the date of this Information Statement/Prospectus, there were a total
of 270,254 shares of LSI Common Stock and 642,279 shares of LSI Series 1
Preferred Stock outstanding. Accordingly, assuming no changes in such
capitalization between the date hereof and the date on which written consents
with respect to the Merger are obtained by management of LSI, the Merger will be
approved if the holders of 456,267 shares of LSI Common Stock and LSI Series 1
Preferred Stock (assuming conversion of the LSI Series 1 Preferred Stock into
shares of LSI Common Stock at the then applicable conversion price as provided
in LSI's Restated Certificate of Incorporation), voting together as a single
class, and the holders of 428,186 shares of LSI Series 1 Preferred Stock, voting
separately as a class, execute written consents in favor of the Merger. As of
the date

and their respective affiliates hold, directly or indirectly, (i) 776,967, or
approximately 85.14%, of the combined total of outstanding shares of LSI Common
Stock and LSI Series 1 Preferred Stock (assuming for purposes of voting the

Stock, LSI Common Stock and LSI Series 1 Preferred Stock."
 
     As of November 1, 1996, approximately 1.7% of the shares of outstanding
Thermo Common Stock were held by directors and executive officers of Thermo and
its affiliates, and approximately 93% of such shares were held by Thermo
Instrument. The vote of the stockholders of Thermo is not required to approve
the Merger Agreement or to consummate the Merger. See "The Merger -- Background
of the Merger and Related Matters."
 
RESALE OF THERMO COMMON STOCK RECEIVED IN THE MERGER
 
     The Registration Statement and this Information Statement/Prospectus do not
relate to or cover the resale after the Effective Time of shares of Thermo
Common Stock issued to certain shareholders of LSI in the Merger who may be
deemed to be "affiliates" of LSI and thus "underwriters" within the meaning of
Rule 145 under the Securities Act of 1933, as amended (the "Securities Act"),
and no person is authorized to make any use of this Information
Statement/Prospectus in connection with any such resale. Such securities may not
be publicly reoffered or resold by such persons except pursuant to an effective
registration statement under the Securities Act or pursuant to another
applicable exemption therefrom. For this purpose, the term "affiliate" means any
person who directly, or indirectly through one or more intermediaries, controls,
or is controlled by, or is under common control with, LSI. See "The
Merger -- Resale of Thermo Common Stock Received in the Merger."
 
     The Merger is intended to qualify as a tax-free reorganization under
Section 368(a) of the Internal Revenue Code of 1986, as amended (the "Code"). In
order for the Merger to so qualify, the LSI shareholders must have the requisite
"continuity of interest" prescribed in rulings made by the Internal Revenue
Service. This requirement may restrict the ability of LSI shareholders to
dispose of shares of Thermo Common Stock acquired by them in the Merger. See
"Certain Federal Income Tax Consequences."
 
     The LSI Option Plan has been designed to provide options to purchase shares
of LSI Common Stock that are qualified as incentive stock options ("ISOs") under
the Code. It is a condition to Thermo's obligation to consummate the Merger that
all LSI Options be exercised or cancelled and terminated (at no cost to LSI)
prior to the Effective Time. The requirements of the Code regarding preservation
of the ISO status of an option upon exercise thereof may restrict the ability of
holders of LSI Options to dispose of shares of Thermo Common Stock acquired by
them in the Merger. See "Certain Federal Income Tax Consequences."
 
ACCOUNTING TREATMENT; REGULATORY APPROVALS
 
     Thermo intends to account for the merger using the purchase method of
accounting. Under this method, Thermo will be treated as the acquiror of LSI
and, as a result, the purchase price will be allocated based on the fair value
of the assets of LSI acquired and the liabilities assumed.
 
     Except for filings with the Secretary of State of the State of Delaware and
"blue sky" filings with certain states in which LSI shareholders are resident,
no federal or state regulatory approvals are required in order to consummate the
Merger.
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
     The Merger is intended to qualify as a tax-free reorganization under
Section 368(a) of the Code. Neither LSI nor Thermo intends to request a ruling
from the Internal Revenue Service with respect to the Merger. Assuming that the
Merger is a tax-free reorganization, (i) no gain or loss will be recognized by
Thermo or LSI and (ii) no gain or loss will be recognized by shareholders of LSI
receiving solely Thermo Common Stock in the Merger in exchange for their LSI
Capital Stock, other than shareholders perfecting statutory dissenters' rights
or in connection with the cash settlement of fractional shares. In addition,
holders of LSI
 
                                        9
<PAGE>   13
 
Common Stock acquired by exercise of an LSI Option that qualified as an ISO
under the Code would not have a "disqualifying disposition" upon receipt of
Thermo Common Stock in the Merger (such individuals must, nevertheless, comply
with applicable holding periods for stock acquired upon exercise of an ISO). If
the Merger were to fail to qualify as a reorganization under Section 368(a) of
the Code, at the Effective Time each shareholder of LSI would recognize gain or
loss on the exchange of that shareholder's LSI Capital Stock for Thermo Common
Stock and holders of LSI Common Stock acquired upon exercise of an ISO would
have a "disqualifying disposition" under the Code. See "Certain Federal Income
Tax Consequences" and "The Merger -- Treatment of LSI Options." Holders of LSI
Capital Stock, LSI Options and LSI Warrants are urged to consult with their tax
advisers to determine the particular tax consequences of the Merger to them.

     The following table presents unaudited per share data for Thermo Common
Stock and LSI Common Stock on an historical and pro forma combined basis and for
LSI Capital Stock on a pro forma equivalent basis giving effect to the
acquisition of all of the outstanding LSI Capital Stock by Thermo. The
information is derived from the historical financial statements of Thermo and
LSI, including the related notes thereto, included elsewhere in this Information
Statement/Prospectus. The information as of and for the three- and nine-month
periods ended September 30, 1996 is derived from unaudited interim consolidated
financial statements of Thermo and LSI.
 
     Pro forma combined per Thermo share equivalent data has been calculated
based on the pro forma combined data for Thermo Common Stock, multiplied by
 .2074, which is the fraction of a Thermo share into which one share of LSI
Common Stock would be exchanged pursuant to the Merger, assuming an Average
Price of $12.36875. The actual Average Price may be greater than or less than
$12.36875.
 
     This data is not necessarily indicative of the results of the future
operations of the combined entity or the actual results that would have occurred
had the Merger been consummated prior to the periods indicated.

                                   THE MERGER
 
BACKGROUND OF THE MERGER AND RELATED MATTERS
 
     As part of its growth strategy, Thermo actively seeks the acquisition of
products and technologies that complement and augment its existing product
lines. To this end, R. Zach Moseley, General Manager of Corion, contacted Joseph
Caruso, a member of the Board of Directors of LSI, in late April 1996 to express
Thermo's interest in a possible strategic combination between Thermo and LSI. On
May 6, 1996, Mr. Moseley met with Kenneth Greenberg, LSI's President, and Mr.
Moseley and Mr. Greenberg discussed the respective businesses of Thermo and LSI
and their strategic fit. The parties agreed to meet again for further
preliminary discussions.
 
     On May 22, 1996, Kristine Langdon, President of Thermo Vision, and Mr.
Moseley met with Mr. Caruso and Mr. Greenberg. During the meeting, Ms. Langdon
and Mr. Moseley reviewed Thermo's history and its interest in the laser markets.
Mr. Caruso and Mr. Greenberg reviewed LSI's history and future business plans.
In addition to the discussion, Ms. Langdon and Mr. Moseley toured the LSI
facility.
 
     On May 24, 1996, Ms. Langdon presented a nonbinding proposal, subject to
the satisfactory completion of due diligence, to acquire LSI. The proposed
transaction would be subject to customary regulatory approvals and other
conditions, including the approval of senior management of Thermo to proceed.
The parties continued their negotiations regarding the terms of the merger
throughout June and July 1996. On July 22, 1996, Ms. Langdon reviewed Thermo's
business evaluation of LSI with senior management of Thermo and Thermo Electron
and received approval to make an offer to acquire LSI.
 
     On July 31, 1996, the parties entered into a Letter of Intent which
outlined the terms pursuant to which Thermo would acquire LSI in a transaction
intended to be a tax-free exchange of LSI Capital Stock for stock of either
Thermo, Thermo Instrument or Thermo Electron (at Thermo's option) valued at
approximately $3.4 million.
 
     On September 20, 1996, Ms. Langdon, Mr. Moseley, Mr. Caruso and Mr.
Greenberg, together with counsel to Thermo and LSI, met to discuss Thermo's
preference that its own capital stock be exchanged for LSI Capital Stock in the
acquisition. Mr. Caruso and Mr. Greenberg agreed to discuss the matter further,
and subsequently conveyed LSI's acceptance to Thermo's proposal. Numerous
telephone conversations and meetings among counsel for Thermo and LSI ensued.
During October and November 1996, Thermo and LSI negotiated the terms of the
Merger Agreement and related agreements. On November      , 1996, the Merger
Agreement was executed.
 
THERMO'S REASONS FOR THE MERGER
 
     Thermo's purpose for engaging in the transactions contemplated by the
Merger Agreement is to acquire LSI. Thermo believes that the acquisition of LSI
will complement the activities of several of its subsidiaries within its Thermo
Vision group. The structure of the Merger was established to achieve the general
objectives of Thermo, in light of relevant financial, legal, tax and other
considerations. See "Certain Federal Income Tax Consequences."
 
LSI'S REASONS FOR THE MERGER
 
     LSI's purpose for engaging in the transactions contemplated by the Merger
Agreement is to capture the benefits of integration with Thermo's technology and
resources. In addition, the Merger's structure allows LSI stockholders to
acquire Thermo shares, a more liquid investment than LSI shares, in a
transaction intended to qualify as a tax-free reorganization. See "Certain
Federal Income Tax Consequences."
 
RECOMMENDATION OF LSI MANAGEMENT
 
     The management of LSI, including all of the members of LSI's Board of
Directors, have approved the Merger Agreement and the transactions contemplated
thereby and believe the Merger and the other transactions contemplated by the
Merger Agreement are fair to and in the best interests of LSI and its
shareholders. THE MANAGEMENT AND BOARD OF DIRECTORS OF LSI RECOMMEND THAT LSI
SHAREHOLDERS EXECUTE WRITTEN CONSENTS IN FAVOR OF THE ADOPTION AND
 
                                       14
<PAGE>   18
 
APPROVAL OF THE MERGER AGREEMENT AND THE TRANSACTIONS CONTEMPLATED THEREBY.
 
REQUIRED VOTE
 
     Under Delaware Law and pursuant to LSI's Restated Certificate of
Incorporation and By-Laws, the affirmative vote of (i) the holders of at least a
majority of the outstanding shares of LSI Common Stock and LSI Series 1
Preferred Stock voting together as a single class (assuming for purposes of such
vote the shares of LSI Series 1 Preferred Stock were converted into shares of
LSI Common Stock at the then applicable conversion price as provided in LSI's
Restated Certificate of Incorporation) and (ii) the holders of at least
sixty-six and two-thirds percent (66 2/3%) of the outstanding shares of LSI
Series 1 Preferred Stock, voting separately as a class, are required to approve
the Merger Agreement and the transactions contemplated thereby. In addition, it
is a condition to Thermo's obligation to consummate the Merger that the Merger
and the adoption of the Merger Agreement shall have been approved by the holders
of at least 95% of the outstanding shares of each of the LSI Common Stock and
the LSI Series 1 Preferred Stock.
 
     In accordance with LSI's Restated Certificate of Incorporation and Delaware
Law, the Merger and the Merger Agreement may be approved and adopted without a
stockholders meeting by the written consent of the holders of shares holding the
requisite percentage of the votes entitled to be cast thereon. As a result,
management of LSI will be requesting that LSI stockholders who elect to do so
approve and adopt the Merger and the Merger Agreement by executing written
consents thereto. In the event that written consents of the holders of shares
holding the requisite percentage of votes entitled to be cast thereon are
obtained, no further action will be required by the stockholders under Delaware
Law to approve the Merger and the Merger Agreement.
 
     Under Section 228 of the Delaware Law, prompt notice of the taking of
corporate action without a meeting by less than unanimous consent is required to
be given to any stockholders who have not consented thereto in writing. Such
notice of the actions described above will be given in writing by LSI promptly
following the Effective Time.
 
STRUCTURE AND TERMS OF THE MERGER
 
     The detailed terms of and conditions to the Merger are contained in the
Merger Agreement, which is included in full as Appendix A to this Information
Statement/Prospectus and incorporated herein by reference. The description of
the terms of the Merger contained herein is qualified in its entirety by, and
made subject to, the more complete information set forth in the Merger
Agreement.
 
     If the Merger is consummated, the outstanding shares of Acquisition Corp.
will be converted into new shares of LSI Common Stock (which will be held by
Thermo) and all of the previously outstanding shares of LSI Capital Stock (other
than any such shares held in the treasury of LSI and shares with respect to
which dissenters' rights are perfected) will be converted into shares of Thermo
Common Stock. As a result of the Merger, LSI will become a wholly owned
subsidiary of Thermo, and each person who previously held shares of LSI Capital
Stock (other than those who perfected statutory dissenters' rights) will
receive, upon the surrender of their stock certificates to a designated agent of
Thermo, a fraction of a share of Thermo Common Stock for each share of LSI
Common Stock held. The assumed value of each share of Thermo Common Stock to be
issued in the Merger will be determined based on the average closing price for
such stock on the American Stock Exchange during the 20 trading days prior to
the date on which the Effective Time occurs (the "Average Price"). The total
number of shares of Thermo Common Stock to be issued in the Merger will be equal
to the quotient derived by dividing $3,400,000 by the Average Price.
 
     Currently, there are 1,325,605 shares of LSI Common Stock outstanding on a
fully diluted basis (that is, assuming the conversion of all shares of LSI
Series 1 Preferred Stock into LSI Common Stock and the exercise of all options
and warrants to purchase shares of LSI Capital Stock). Thus, for example, based
on the average closing price of the Thermo Common Stock on the American Stock
Exchange during the 20 trading days ended on November 15, 1996, $12.36875, and
assuming no LSI shareholders exercise appraisal rights, upon consummation of the
Merger, LSI shareholders would receive, in exchange for each share of LSI Common
Stock owned at the Effective Time, .2074 shares of Thermo Common Stock, and a
total of approximately 274,930 shares of Thermo Common Stock would be issued in
connection with the Merger. As a
 
                                       15
<PAGE>   19
 
result, a total of approximately 48,724,930 shares of Thermo Common Stock would
then be outstanding, of which approximately 274,930 shares, representing
approximately 0.56% of the total, would be held by former shareholders of LSI
Capital Stock. HOWEVER, THE AVERAGE CLOSING PRICE FOR THE THERMO COMMON STOCK
DURING THE 20 TRADING DAYS PRIOR TO THE DATE ON WHICH THE EFFECTIVE TIME OCCURS
MAY BE MORE OR LESS THAN $12.36875. FURTHER, THE MERGER AGREEMENT PROVIDES THAT,
IF THE AVERAGE PRICE IS LESS THAN $10.97, THEN THERMO MAY ELECT NOT TO
CONSUMMATE THE MERGER. IN SUCH CASE, THERMO WOULD BE RESPONSIBLE FOR THE PAYMENT
OF LSI'S FEES AND EXPENSES INCURRED IN CONTEMPLATION OF THE MERGER, UP TO A
MAXIMUM OF $       .
 
TREATMENT OF LSI OPTIONS
 
     It is a condition to Thermo's obligation to consummate the Merger that,
prior to the Effective Time, all LSI Options shall have been exercised in
accordance with their terms or canceled and terminated (at no cost to LSI) with
the consent of the holders thereof. In connection with this condition, as part
of the LSI shareholders' written consent to the Merger, LSI management intends
to seek the approval of the LSI shareholders to an amendment to the LSI Option
Plan that would accelerate the vesting of all LSI Options so that they are
immediately exercisable prior to the Effective Time. Under the terms of the LSI
Option Plan, the affirmative vote of the holders of at least a majority of the
outstanding LSI Common Stock is required to approve such an amendment. See "The
Merger -- Conditions to Consummation of the Merger."
 
TREATMENT OF LSI WARRANTS
 
     It is a condition to Thermo's obligation to consummate the Merger that,
prior to the Effective Time, all outstanding LSI Warrants are exercised in
accordance with their terms or canceled and terminated (at no cost to LSI) with
the consent of the holders thereof.
 
INDEMNIFICATION OF THERMO; ESCROW
 
     Upon consummation of the Merger, twenty percent of the shares of Thermo
Common Stock issued in the Merger will be delivered into escrow (the "Indemnity
Escrowed Shares") and held pursuant to the Indemnification and Stock Escrow
Agreement attached as Exhibit A to the Merger Agreement (the "Escrow
Agreement"). The Indemnity Escrowed Shares will be reserved to provide
collateral for indemnification to Thermo against costs, liabilities or damages
incurred, paid by or imposed upon Thermo, Acquisition Corp. or LSI after the
Effective Time as a result of misrepresentations, breaches of warranties and
breaches of covenants contained in the Merger Agreement, the Escrow Agreement
and any other agreements executed in connection therewith. IT SHOULD BE
UNDERSTOOD THAT THE ACTUAL AMOUNT OF DAMAGES TO THERMO FOR CERTAIN
MISREPRESENTATIONS OR BREACHES FOR WHICH THE LSI SHAREHOLDERS MAY BE HELD
RESPONSIBLE PURSUANT TO THE MERGER AGREEMENT MAY BE MORE THAN THE VALUE OF SUCH
ESCROWED SHARES. SEE ARTICLE VI OF THE MERGER AGREEMENT AND SECTION 4 OF THE
ESCROW AGREEMENT FOR A DESCRIPTION OF THE REPRESENTATIONS AND WARRANTIES THAT
ARE COVERED BY THE ESCROW AGREEMENT.
 
     In the event Thermo has an appropriate claim for indemnification, Indemnity
Escrowed Shares held in the escrow account will be returned to Thermo in
satisfaction of the claim. The amount of indemnification to which Thermo would
be entitled with respect to an indemnifiable claim (the "Indemnifiable Amount")
shall be determined and computed by reference to all losses to Thermo,
Acquisition Corp. and/or LSI (including, without limitation, diminution in value
of the shares of the capital stock of LSI) and shall be deemed to include all
losses, liabilities, expenses or costs incurred by Thermo, Acquisition Corp.
and/or LSI, including reasonable attorneys' fees.
 
     If a claim is made, the escrow agent will deliver to Thermo an amount of
shares with a total value equal to the Indemnifiable Amount within 30 days of
the demand unless written objection to such demand is received by the escrow
agent and Thermo from the Shareholder Representative (as defined below). If the
Shareholder Representative objects to Thermo's claim, the dispute may be
submitted to a court of competent jurisdiction if not previously settled.
 
     [Joseph Caruso] has agreed to serve as representative of the former LSI
shareholders for purposes of the Escrow Agreement (the "Shareholder
Representative"). Any action taken by the Shareholder Representative with
respect to the settlement of a claim against the escrowed shares will be binding
on all former LSI shareholders. The Shareholder Representative will have the
right to sell shares of Thermo Common Stock
 
                                       16
<PAGE>   20
 
held in escrow in order to obtain funds to pay any expenses incurred or
anticipated to be incurred in connection with his services.
 
     The Escrow Agreement requires the escrow agent to deliver to the former LSI
shareholders the Indemnity Escrowed Shares remaining in escrow eighteen months
after the Effective Time, except that if there is a claim by Thermo at or prior
to such date, the escrow agent will retain Indemnity Escrowed Shares in an
amount sufficient to cover such claims until they are resolved. LSI is not aware
of any claims threatened or asserted that it expects to give rise to a right of
indemnification under the Escrow Agreement. IT SHOULD BE UNDERSTOOD, HOWEVER,
THAT CLAIMS FOR DAMAGES DUE TO BREACHES OF CERTAIN REPRESENTATIONS AND
WARRANTIES CONTAINED IN THE MERGER AGREEMENT MAY ARISE IN AMOUNTS GREATER THAN
THE TOTAL VALUE OF ALL OF THE INDEMNITY ESCROWED SHARES. THIS WOULD RESULT IN
ALL OF THE INDEMNITY ESCROWED SHARES BEING EITHER DISTRIBUTED TO THERMO OR SOLD
BY THE SHAREHOLDER REPRESENTATIVE PURSUANT TO THE ESCROW AGREEMENT, IN WHICH
EVENT NONE OF THE INDEMNITY ESCROWED SHARES WOULD BE DISTRIBUTED TO THE
SHAREHOLDERS AT THE END OF THE ESCROW PERIOD, AND THE LSI SHAREHOLDERS WOULD
REMAIN LIABLE TO THERMO FOR DAMAGES RELATING TO ANY SUCH REMAINING CLAIMS, UP TO
THE MAXIMUM LIABILITY SET FORTH IN THE MERGER AGREEMENT AND THE ESCROW
AGREEMENT.
 
     For purposes of determining the number of Indemnity Escrowed Shares, which
would be returned to Thermo in satisfaction of a claim, each share will be
valued at the average closing price for the Thermo Common Stock on the American
Stock Exchange during the 20 trading days prior to the date on which the
Effective Time occurs. Thus, for purposes of satisfying the indemnification
requirements of the Escrow Agreement, the former LSI shareholders would not have
the benefit of any increase, nor the risk of any decrease, in the market price
of shares of Thermo Common Stock after the Effective Time.
 
     Shares held in escrow will be registered in the name of the escrow agent,
and the shareholders will be entitled to instruct the escrow agent how to vote
his, her or its shares with respect to matters placed before the Thermo
shareholders. LSI shareholders will be entitled to directly receive cash
dividends, if any, paid or declared out of earned surplus on the escrowed shares
during the escrow period; however, any additional shares of Thermo Common Stock
or other property that are distributed with respect to the escrowed shares
during the escrow period will be held pursuant to the Escrow Agreement to
satisfy any indemnification claims.
 
PROCEDURE FOR EXCHANGE OF SHARES; FRACTIONAL SHARES
 
     Promptly following the consummation of the Merger,             , acting in
the capacity of exchange agent (the "Exchange Agent") will mail to each former
shareholder of LSI a form of letter of transmittal, together with instructions
for the exchange of such holder's certificates representing LSI Common Stock for
certificates representing shares of Thermo Common Stock. Upon surrender to the
Exchange Agent of one or more certificates for LSI Common Stock together with a
properly completed letter of transmittal, the Exchange Agent will issue and mail
to the former LSI shareholder a certificate representing a number of shares of
Thermo Common Stock that is equal to the number of shares of Thermo Common Stock
into which such shares of LSI Common Stock have been converted pursuant to the
Merger (less such shareholder's pro rata portion of the Indemnity Escrowed
Shares), and, where applicable, a check for the amount representing any
fractional share determined in the manner described in the following paragraph.
 
     Neither certificates nor scrip for fractional shares of Thermo Common Stock
shall be issued to LSI shareholders and no LSI shareholder shall be entitled to
any voting or other rights of a holder of shares of a fractional share interest.
Each LSI shareholder who otherwise would have been entitled to receive a
fraction of a share of Thermo Common Stock shall receive cash in lieu thereof,
without interest, in an amount determined by multiplying such shareholder's
fractional interest by the Average Price. All amounts of cash in respect of
fractional interests which have not been claimed at the end of three years from
the Effective Time by surrender of certificates of LSI Capital Stock for shares
of Thermo Common Stock shall be repaid to LSI subject to the provisions of
applicable escheat or similar laws, for the account of the holders entitled
thereto.
 
                                       17
<PAGE>   21
 
          LSI SHAREHOLDERS SHOULD NOT SEND IN THEIR CERTIFICATES UNTIL
          THEY RECEIVE THE LETTER OF TRANSMITTAL FORM AND INSTRUCTIONS
                            FROM THE EXCHANGE AGENT.
 
MANAGEMENT AND OPERATIONS OF LSI AFTER THE MERGER
 
     It is contemplated that, after the Merger, LSI will continue to operate as
a separate entity. Thermo does not presently intend to change the domicile, name
or material operations of LSI, except that it is anticipated that LSI's
operations will be moved to Thermo's Franklin, Massachusetts facility after the
expiration of its lease in February 1997. In addition, Thermo has advised LSI
that Earl R. Lewis, Kristine A. Langdon and R. Zach Moseley will be named as the
sole directors of LSI. Thermo currently intends that the existing officers of
LSI will retain their offices after the Effective Time, but may appoint
additional officers of LSI from time to time. See "Thermo and LSI Management and
Executive Compensation -- Executive Officers and Directors of LSI."
 
EFFECTIVE TIME
 
     The Merger shall become effective upon the date of filing of the Merger
Agreement, together with certain officers' certificates, or a Certificate of
Merger, with the Secretary of State of the State of Delaware pursuant to Section
103 of the Delaware Law, or such other time as may be specified in the Merger
Agreement. It is anticipated that the Effective Time will occur on December 27,
1996.

CONDUCT OF LSI'S BUSINESS PENDING THE MERGER
 
     LSI has agreed to conduct its operations prior to the Effective Time in the
ordinary course of business and in compliance with all applicable laws and
regulations. LSI has further agreed, prior to the Effective Time, to (i) use its
best efforts to preserve intact its current business organization, (ii) keep its
physical assets in good working condition, (iii) keep available the services of
its current officers and employees and (iv) preserve its relationships with
customers, suppliers and others having business dealings with it to the end that
its goodwill and ongoing business shall not be impaired in any material respect.
 
     Subject to certain exceptions, LSI has also agreed that prior to the
Effective Time, it will not engage in certain types of transactions without the
prior written consent of Thermo, including, among other transactions, (i)
entering into, adopting or amending any employee benefit plan (other than the
LSI Option Plan as described under the caption "-- Treatment of LSI Options") or
employment or severance agreement or, except for normal increases in the
ordinary course of business, increase the compensation or fringe benefits of, or

person or entity, (iii) amending its Restated Certificate of Incorporation or
By-Laws, (iv) acquiring, selling, leasing, encumbering or disposing of any

                                       19
<PAGE>   23
 
course of business, (v) issuing, selling, redeeming or repurchasing, or
authorizing the issuance, sale or delivery of, any shares of capital stock or
any other securities, rights, warrants or options to acquire any such capital

existing convertible securities, stock option agreements and warrants, or

RESALE OF THERMO COMMON STOCK RECEIVED IN THE MERGER
 
     The shares of Thermo Common Stock to be issued in the Merger to the LSI
shareholders pursuant to the Merger Agreement have been registered under the
Securities Law, thereby allowing such shares to be freely traded without
restriction by persons who are not deemed to be "affiliates," as that term is
defined in the Securities Law, of Thermo or of LSI. Certain officers, directors
and principal shareholders of LSI may be deemed to be affiliates of LSI and thus
"underwriters" within the meaning of Rule 145 under the Securities Law. Such
persons will not be able to resell the Thermo Common Stock received by them in
the Merger except pursuant to an effective registration statement under the
Securities Law or pursuant to another applicable exemption therefrom. All
persons who may be deemed to be affiliates should carefully consider the
limitations imposed by Rules 144 and 145 under the Securities Law prior to
effecting resales of the Thermo Common Stock.
 
     The Merger is intended to qualify as a tax-free reorganization under
Section 368(a) of the Code. In order for the Merger to so qualify, the LSI
shareholders must have the requisite "continuity of interest" prescribed in
rulings made by the Internal Revenue Service. This requirement may restrict the
ability of LSI shareholders to dispose of shares of Thermo Common Stock acquired
by them in the Merger. See "Certain Federal Income Tax Consequences."
 
     The LSI Option Plan has been designed by LSI to provide options to purchase
shares of LSI Common Stock that are qualified as ISOs under the Code. It is a
condition to Thermo's obligation to consummate the Merger that all LSI Options
be exercised or cancelled and terminated (at no cost to LSI) prior to the
Effective Time. The requirements of the Code regarding preservation of the ISO
status of an option upon exercise thereof may restrict the ability of holders of
LSI Options to dispose of shares of Thermo Common Stock acquired by them in the
Merger. See "Certain Federal Income Tax Consequences."
 
ACCOUNTING TREATMENT; REGULATORY APPROVALS
 
     Thermo intends to account for the Merger using the purchase method of
accounting. Under this method, Thermo will be treated as the acquiror of LSI
and, as a result, the purchase price will be allocated based on the fair value
of the assets of LSI acquired and the liabilities assumed.
 
     Except for filings with the Secretary of State of the State of Delaware and
"blue sky" filings with certain states in which LSI shareholders are resident,
no federal or state regulatory approvals are required in order to consummate the
Merger.
 
                                       20

TERMINATION, AMENDMENTS AND EXPENSES
 
     The Merger Agreement may be terminated and the Merger contemplated thereby
abandoned at any time prior to the consummation of the Merger by the mutual
written consent of Thermo and LSI. The Merger Agreement may be terminated by
Thermo or LSI acting alone, (i) if there shall be any order of a court in effect
to prevent consummation of the Merger Agreement or (ii) if there shall be any
action taken, or any statute, rule, regulation or order enacted, promulgated,
issued or deemed applicable to the Merger Agreement or the transactions
contemplated thereby, by any governmental entity that would make the
consummation of the Merger Agreement illegal or (iii) if there is a failure to
obtain the requisite approval from LSI's shareholders of the Merger Agreement.
Thermo may terminate the Merger Agreement if (a) the Merger has not been
consummated by the close of business on December 27, 1996 by reason of the
failure of any condition precedent under Section 5.1 or 5.2 of the Merger
Agreement (unless the failure results from a breach of any representation,
warranty or covenant contained in the Merger Agreement made or to be performed
by Thermo or Acquisition Corp.) or (b) the Average Price is less than $10.97.
LSI may terminate the Merger Agreement if the Merger has not been consummated by
the close of business on December 27, 1996 by reason of the failure of any
condition precedent under Section 5.1 or 5.3 of the Merger Agreement (unless the
failure results from any breach of any representation, warranty or covenant
contained in the Merger Agreement made or to be performed by LSI).
 
     In the event that the Merger is terminated in accordance with the terms of
the Merger Agreement, each party will be responsible for the costs incurred by
it in connection with the transactions contemplated by the Merger Agreement,
except that if Thermo elects to terminate the Merger because the Average Price
is less than $10.97, Thermo will be responsible for the fees and expenses
incurred by LSI in contemplation of the Merger up to a maximum of $     .
 
CERTAIN EFFECTS OF THE MERGER
 
     Upon consummation of the Merger the present holders of LSI Capital Stock
(other than holders of shares with respect to which statutory dissenters' rights
are perfected) will receive an equity interest in a large company of which LSI
will be a small part. Thermo will continue to be subject to the periodic
reporting requirements of the Exchange Act and, under current regulations
promulgated thereunder, will continue to furnish information to the Commission
so long as any securities of Thermo are listed on a national securities exchange
or held of record by at least 300 holders. See "Available Information". It is a
condition to LSI's and Thermo's obligations under the Merger Agreement that the
shares of Thermo Common Stock to be issued in connection with the Merger be
listed on the American Stock Exchange, or approved for listing on the American
Stock Exchange subject to official notice of issuance. See "The Merger --
Conditions to Consummation of the Merger."
 
     None of the LSI Capital Stock is presently, or will be after the Merger,
listed or traded in any established market.
 
     It is expected that, following the Merger, Thermo will continue to operate
the business of LSI in substantially the same manner as it has been operating.
However, Thermo will continue to evaluate LSI's business and operations
following the Merger and will make such changes as are deemed appropriate.
 
     If the Merger is consummated, the holders of LSI Capital Stock (other than
holders of shares with respect to which statutory dissenters' rights are
perfected) will exchange their shares of LSI Capital Stock for Thermo Common
Stock. The rights of LSI shareholders, which are presently governed by Delaware
Law and by the Restated Certificate of Incorporation and By-Laws of LSI, will be
governed by Delaware Law and the Certificate of Incorporation and By-Laws of
Thermo. Certain differences in the rights of LSI shareholders will arise as a
result of distinctions between the treatment of public companies and private
companies under Delaware Law, as well as distinctions between the Restated
Certificate of Incorporation and By-Laws of LSI and the Certificate of
Incorporation and By-Laws of Thermo. See "Comparison of Rights of Holders of
Thermo Common Stock and LSI Capital Stock."
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
     Shareholders should be aware that certain officers and directors of LSI
have interests, described below, which may present them with potential conflicts
of interest in connection with the transaction. Management of
 
                                       21
<PAGE>   25
 
LSI and members of the Board of Directors of LSI are aware of the conflicts
described below and considered them in addition to the other matters described
under "The Merger -- LSI's Reasons for the Merger."
 
     Upon consummation of the Merger, all of the members of LSI's Board of
Directors will resign, and Thermo intends to name Earl R. Lewis, Kristine A.
Langdon and R. Zach Moseley as the sole Directors of LSI. Thermo currently
intends that the existing officers of LSI will retain their offices after the
Effective Time, but may appoint additional officers of LSI from time to time.
 
     It is expected that, at the Effective Time, Thermo and Kenneth Greenberg,
President of LSI, will enter into an agreement pursuant to which Thermo will
guarantee the payment of Mr. Greenberg's salary for one year following the date
on which the Effective Time occurs, subject to certain exceptions.
 
                       RIGHTS OF DISSENTING SHAREHOLDERS
 
     THE FOLLOWING DISCUSSION IS NOT A COMPLETE STATEMENT OF THE LAW PERTAINING
TO APPRAISAL RIGHTS UNDER DELAWARE LAW AND IS QUALIFIED IN ITS ENTIRETY BY THE
FULL TEXT OF SECTION 262 OF THE DELAWARE LAW ("SECTION 262") WHICH IS REPRINTED
IN ITS ENTIRETY AS APPENDIX B TO THIS INFORMATION STATEMENT/PROSPECTUS.
 
     Under Delaware Law, if the Merger is consummated, holders of shares of LSI
Common Stock or LSI Series 1 Preferred Stock ("Shares") who follow the
procedures set forth in Section 262 will be entitled to have their Shares
appraised by the Delaware Chancery Court (the "Court") and to receive payment of
the "fair value" of such Shares, exclusive of any element of value arising from
the accomplishment or expectation of the Merger, together with a fair rate of
interest, as determined by the Court.
 
     Under Section 262, where a merger is approved and adopted by written
consent of stockholders, the corporation, either before the effective time of
the merger or within ten days thereafter, must notify each of its stockholders
entitled to appraisal rights that such appraisal rights are available and
include in such notice a copy of Section 262. Such notice to the holders of
Shares and the applicable statutory provisions of the Delaware Law, which are
attached to this Information Statement/Prospectus as Appendix B, will be sent to
all holders of LSI Capital Stock. Any LSI stockholder who wishes to exercise
such appraisal rights or who wishes to preserve his right to do so, should
review the following discussion and Appendix B carefully because failure to
timely and properly comply with the procedures specified will result in the loss
of appraisal rights under Delaware Law.
 
     A HOLDER OF SHARES WISHING TO EXERCISE HIS APPRAISAL RIGHTS MUST DELIVER A
WRITTEN DEMAND FOR APPRAISAL OF HIS SHARES TO LSI (AS THE SURVIVING CORPORATION
IN THE MERGER) SO THAT IT IS RECEIVED BY LSI BY NO LATER THAN THE DATE WHICH IS
20 DAYS AFTER THE NOTICE DESCRIBED ABOVE IS MAILED. In addition, a holder of
Shares wishing to exercise his appraisal rights must hold of record such Shares
on the date the written demand for appraisal is made and at the Effective Time.
 
     Only a holder of record of Shares is entitled to assert appraisal rights
for the Shares registered in that holder's name. A demand for appraisal should
be executed by or on behalf of the holder of record, fully and correctly, as his
name appears on his stock certificates. If the Shares are owned of record in a
fiduciary capacity, such as by a trustee, guardian or custodian, execution of
the demand should be made in that capacity, and if the Shares are owned of
record by more than one person, as in a joint tenancy or tenancy in common, the
demand should be executed by or on behalf of all joint owners. An authorized
agent, including one or more joint owners, may execute a demand for appraisal on
behalf of a holder of record; however, the agent must identify the record owner
or owners and expressly disclose the fact that, in executing the demand, the
agent is agent for such owner or owners. A record holder such as a broker who
holds Shares as nominee for several beneficial owners may exercise appraisal
rights with respect to the Shares held for one or more beneficial owners while
not exercising such rights with respect to the Shares held for other beneficial
owners; in such case, the written demand should set forth the number of Shares
as to which appraisal is sought and where no number of Shares is expressly
mentioned the demand will be presumed to cover all Shares held in the name of
the record owner. Stockholder of LSI who hold their Shares in brokerage accounts
or other nominee forms and who wish to exercise appraisal rights are urged to
consult with their brokers to determine the appropriate procedures for the
making of a demand for appraisal by such a nominee.
 
                                       22
<PAGE>   26
 
     All written demands for appraisal should be sent or delivered to LSI, c/o
Elizabeth Murley, Thermo Electron Corporation, 81 Wyman Street, Waltham,
Massachusetts 02254.
 
     Within 120 days after the Effective Time, but not thereafter, LSI or any
stockholder of LSI who has complied with the statutory requirements summarized
above may file a petition with the Court demanding a determination of the fair
value of the Shares and if such petition is filed by a former LSI stockholder, a
copy of such petition shall also be sent to LSI. LSI is under no obligation to
and has no present intention to file a petition with respect to the appraisal of
the fair value of the Shares. Accordingly, it is the obligation of an LSI
stockholder to initiate all necessary action to perfect his appraisal rights
within the time prescribed in Section 262.
 
     Within 120 days after the Effective Time, any LSI stockholder who has
complied with the requirements for exercise of appraisal rights will be
entitled, upon written request, to receive from LSI a written statement setting
forth the aggregate number of Shares not voted in favor of the Merger and with
respect to which demands for appraisal have been received and the aggregate
number of holders of such Shares. Such statements must be mailed within ten days
after a written request therefor has been received by LSI or within ten days
after expiration of the period for delivery of demands for appraisal under
Section 262, whichever is later.
 
     If a petition for an appraisal is timely filed, at the hearing on such
petition, the Court will determine the stockholders entitled to appraisal rights
and will appraise the fair value of their Shares, exclusive of any element of
value arising from the accomplishment or expectation of the Merger, together
with a fair rate of interest, if any, to be paid upon the amount determined to
be the fair value. The Court may appoint one or more appraisers to determine the
fair value of the Shares and to make a recommendation to the Court. Stockholders
considering seeking appraisal should be aware that the fair value of their
Shares as determined under Section 262 could be more than, the same as or less
than the consideration they would receive pursuant to the Merger Agreement if
they did not seek appraisal of their Shares.
 
     The costs of the action may be determined by the Court and taxed upon the
parties as the Court deems equitable. Upon application of a stockholder, the
Court may also order that all or a portion of the expense incurred by any
stockholder in connection with an appraisal, including, without limitation,
reasonable attorneys' fees and the fees and expenses of experts utilized in the
appraisal proceeding, be charged pro rata against the value of all of the Shares
entitled to appraisal.
 
     Any holder of Shares who has duly demanded an appraisal in compliance with
Section 262 will not, after the Effective Time, be entitled to vote the Shares
subject to such demand for any purpose or be entitled to the payment of
dividends or other distributions on those Shares (except dividends or other
distributions payable to holders of record of Shares as of a record date prior
to the Effective Time).
 
     If any stockholder who properly demands appraisal of his Shares under
Section 262 fails to perfect, or effectively withdraws or loses, his right to
appraisal, as provided in Delaware Law, the Shares of such stockholder will be
converted into the right to receive the consideration receivable with respect to
such Shares in accordance with the Merger Agreement. A stockholder will fail to
perfect, or effectively lose or withdraw, his right to appraisal if, among other
things, (i) such stockholder fails to demand appraisal of his Shares by the date
which is 20 days after the notice regarding appraisal rights is mailed, (ii) no
petition for appraisal is filed within 120 days after the Effective Time or
(iii) the stockholder delivers to LSI a written withdrawal of his demand for
appraisal and acceptance of the Merger, except that any such attempt to withdraw
made more than 60 days after the Effective Time will require the written
approval of LSI.
 
     FAILURE TO FOLLOW THE STEPS REQUIRED BY SECTION 262 FOR PERFECTING
APPRAISAL RIGHTS MAY RESULT IN THE LOSS OF SUCH RIGHTS (IN WHICH EVENT AN LSI
STOCKHOLDER WILL BE ENTITLED TO RECEIVE THE CONSIDERATION RECEIVABLE WITH
RESPECT TO HIS SHARES AS PROVIDED IN THE MERGER AGREEMENT).

                   COMPARISON OF RIGHTS OF HOLDERS OF THERMO
                       COMMON STOCK AND LSI CAPITAL STOCK
 
     Each of LSI and Thermo is incorporated in the State of Delaware. The rights
of the LSI shareholders are currently governed and defined by Delaware Law and
by LSI's Restated Certificate of Incorporation (the "LSI Certificate") and LSI's
By-Laws, as amended (the "LSI By-Laws"). Upon consummation of the Merger, the
LSI shareholders will become stockholders of Thermo and their rights as
stockholders and the internal affairs of Thermo will be governed and defined by
Delaware Law and by Thermo's Certificate of Incorporation (the "Thermo
Certificate") and By-Laws (the "Thermo By-Laws"), which differ in certain
material respects from LSI's Certificate and By-Laws. The following is a summary
of certain differences between the rights of LSI shareholders compared with
those of Thermo stockholders.
 
     The following summary does not purport to be a complete description of the
rights of shareholders of LSI or the rights of stockholders of Thermo or a
comprehensive comparison of such rights, and is qualified in its entirety by
reference to Delaware Law, to the Thermo Certificate and By-Laws and to the LSI
Certificate and By-Laws, to which shareholders are referred. For more
information regarding reviewing or obtaining a copy of either company's
certificate of incorporation or by-laws, see "Available Information."
 
CONTROL OF THERMO BY THERMO INSTRUMENT
 
     Thermo Instrument owns, and immediately after the Merger will continue to
own, approximately 93% of the voting stock of Thermo and intends to maintain at
least an 80% interest in Thermo in the future. Thermo Instrument thus has the
power to elect the entire Board of Directors of Thermo and to approve or
disapprove any corporate actions submitted to a vote of Thermo's shareholders.
See "Relationship of Thermo with Thermo Electron and Thermo Instrument."
 
VOTING POWER; CERTAIN ACTIONS REQUIRING SUPERMAJORITY VOTES
 
     The Delaware Law provides that, unless otherwise provided in a
corporation's certificate of incorporation, each stockholder of a Delaware
corporation shall be entitled to one vote for each share of capital stock held
by such stockholder on all matters submitted to the corporation's shareholders
for their approval. In addition, Delaware Law permits a corporation to specify
in its certificate of incorporation or by-laws the number of votes that shall be
necessary for the transaction of any business by the corporation's shareholders.
In the absence of any such specification, and subject to certain exceptions,
Delaware Law requires the affirmative vote of the holders of a simple majority
of shares present in person or represented by proxy at a meeting and entitled to
vote on the subject matter for the matter to be approved by the corporation's
stockholders.
 
     Thermo.  The Thermo Certificate contains no changes to these general rules.
 
     LSI.  The LSI Certificate provides that most matters presented to the LSI
stockholders for approval may be approved by the holders of a simple majority of
shares of the LSI Common Stock and the LSI Series 1 Preferred Stock present at a
meeting (or acting by written consent), voting together as a single class (the
"LSI Required Vote"). Each share of LSI Common Stock is entitled to one vote and
each share of LSI Series 1 Preferred Stock is entitled to one vote for each
share of LSI Common Stock into which such share of LSI Series 1 Preferred Stock
is convertible. In addition, LSI's Certificate provides that, so long as any
shares of LSI Series 1 Preferred Stock are outstanding, LSI shall not, without
first obtaining the affirmative vote or written consent of the holders of not
less than 66 2/3% of such outstanding shares: (i) amend or repeal any provision
of, or add any provision to, LSI's Certificate or By-laws if such action would
alter or change the preferences, rights, privileges or powers of, or the
restrictions provided for the benefit of, the LSI Series 1 Preferred Stock; (ii)
reclassify any LSI Common Stock into shares having any preference or priority as
to dividends or assets superior to or on a parity with the LSI Series 1
Preferred Stock; (iii) subject to certain exceptions, pay or declare any
dividend or distribution on the LSI Common Stock, or redeem, retire or otherwise
acquire any such stock; (iv) create or issue any other class of stock or series
of preferred stock; or (v) adopt any plan of merger or consolidation or sale of
all or substantially all of LSI's assets.
 
                                       24
<PAGE>   28
 
EXCHANGE OF PREFERRED STOCK FOR COMMON STOCK
 
     Holders of shares of LSI Series 1 Preferred Stock who have converted such
shares into shares of LSI Common Stock prior to the Effective Time will receive
shares of Thermo Common Stock in connection with the Merger. As common
stockholders, such holders will no longer possess the rights, preferences,
privileges and restrictions of preferred stock contained in the LSI Certificate.
For example, such holders will no longer be entitled to dividend or liquidation
preferences, supermajority approval rights or conversion and redemption rights,
and instead will possess the rights and be subject to the limitations of Thermo
Common Stock. See "Description of Thermo Capital Stock."
 
AMENDMENT OF CHARTER AND BY-LAWS
 
     Section 242 of the Delaware Law provides that stockholders may amend their
corporation's certificate of incorporation if a majority of the outstanding
stock entitled to vote thereon, and a majority of the outstanding stock of each
class entitled to vote thereon as a class, has been voted in favor of the
amendment. The Delaware Law also provides that after a corporation has received
any payment for its stock, the power to adopt, amend or repeal by-laws resides
with the stockholders entitled to vote. A corporation may, however, grant to its
board of directors in its certificate of incorporation concurrent power to
adopt, amend or repeal by-laws.
 
     Thermo.  Thermo's Certificate expressly provides that the board of
directors is authorized to adopt, repeal, alter, amend or rescind Thermo's
By-Laws.
 
     LSI.  LSI's Certificate expressly provides that the board of directors is
authorized to adopt, repeal, alter, amend or rescind LSI's By-Laws; however, if
such action would alter or change the preferences, rights, privileges or powers
of, or the restrictions provided in the LSI Certificate for the benefit of, the
LSI Series 1 Preferred Stock, then LSI must first obtain the affirmative vote or
written consent to any such action of the holders of not less than two-thirds of
the outstanding shares of LSI Series 1 Preferred Stock.
 
BOARD OF DIRECTORS
 
     Under Delaware Law, a corporation's board of directors must consist of one
or more individuals, with the number fixed by (or in the manner provided in) the
corporation's by-laws or its certificate of incorporation.
 
     Thermo.  Under Thermo's By-Laws, Thermo's Board shall consist of not less
than one nor more than thirteen directors. Currently, Thermo's Board has set the
number of directors at six. All holders of Thermo Common Stock are entitled to
one vote per share for the election of directors.
 
     LSI.  The LSI By-Laws state that its Board shall consist of between three
and nine directors. Currently, LSI's Board has set the number of directors at
four. The LSI Certificate provides that the holders of the LSI Common Stock
shall be entitled to vote as a separate class for and to elect two members of
the LSI Board of Directors at each meeting of the LSI shareholders held for the
purpose of electing directors. All other members of LSI's Board of Directors may
be elected by obtaining the LSI Required Vote.
 
REMOVAL OF DIRECTORS AND FILLING OF VACANCIES
 
     Delaware Law permits any director or the entire board of directors to be
removed, with or without cause, by the vote of the holders of a majority of the
shares entitled to vote for the election of directors. Both the Thermo By-Laws
and the LSI By-Laws restate this provision of Delaware Law. In addition, both
Thermo's and LSI's By-Laws provide that if the office of any director becomes
vacant, the remaining directors, even if less than a quorum, may by majority
vote elect a successor or successors who shall hold office until the next annual
election of directors.
 
MEETINGS OF THE STOCKHOLDERS
 
     Under Delaware Law, special meetings of stockholders may be called by the
board of directors and by such other person or persons authorized to do so by
the corporation's certificate of incorporation or by-laws. Additionally, if an
annual meeting is not held within 30 days of the date designated for such a
meeting, or is
 
                                       25
<PAGE>   29
 
not held for a period of 13 months after the last annual meeting, the Delaware
Court of Chancery may summarily order a meeting to be held upon the application
of any stockholder or director.
 
     Thermo.  Pursuant to Thermo's By-Laws, special meetings of the shareholders
may be called by the Board of Directors, the Chairman of the Board, if any, the
President or any Vice President.
 
     LSI.  Under LSI's By-Laws, special meetings of the shareholders may be
called by the President and shall be called by the President or Secretary at the
request in writing of stockholders owning a majority in amount of the entire
capital stock of the corporation issued and outstanding and entitled to vote.
Such request must state the purpose or purposes of the proposed meeting.
 
ACTIONS BY STOCKHOLDERS WITHOUT A MEETING
 
     Unless a corporation's certificate of incorporation or articles provide
otherwise, Delaware Law allows any action required to be taken, or which may be
taken, at an annual or special meeting of stockholders to be taken without prior
notice and without a vote so long as the written consent of not less than the
minimum number of votes that would be necessary to authorize or take such action
at a meeting at which all shares entitled to vote thereon were present and voted
is delivered to the corporation.
 
     Thermo.  Thermo's Certificate specifically permits the action of
stockholders by written consent, so long as written consent is given by
shareholders having not less than the minimum percentage of the total vote
required by statute for the corporate action and that prompt notice be given to
all stockholders of the taking of such corporate action without a meeting and by
less than unanimous consent. However, the rules of the American Stock Exchange,
on which the Thermo Common Stock is traded, generally prohibit listed
corporations from taking actions by written consent.
 
     LSI.  LSI's By-Laws contain a provision similar to that of Thermo By-Laws
with respect to actions taken by shareholders without a meeting, except that
notice of the taking of any such action must only be given to those shareholders
who have not so consented.
 
CUMULATIVE VOTING
 
     Under Delaware Law, cumulative voting in the election of directors is
available only if specifically provided for in a corporation's certificate of
incorporation. Neither Thermo's Certificate nor LSI's Certificate provide for
cumulative voting.
 
VOTE REQUIRED FOR CERTAIN MERGERS AND CONSOLIDATIONS; CLASS VOTE FOR CERTAIN
REORGANIZATIONS
 
     Delaware Law provides for a shareholder vote (except as indicated below) of
both the acquiring and acquired corporation to approve mergers, for the sale by
a corporation of all or substantially all of its assets, to approve the
dissolution of a corporation and to approve an amendment to a corporation's
certificate of incorporation. These matters require approval by the holders of a
majority of the shares entitled to vote. Delaware Law does not require a
shareholder vote of the surviving corporation in a merger if (i) the merger
agreement does not amend the existing certificate of incorporation; (ii) each
outstanding or treasury share of the surviving corporation before the merger is
unchanged after the merger; and (iii) the number of shares to be issued by the
surviving corporation in the merger does not exceed 20% of the shares
outstanding immediately prior to such issuance. Delaware Law also does not
require a shareholder vote for certain "short-form mergers" between a parent
company and its subsidiary.
 
     Generally, Delaware Law does not require class voting; however, Delaware
Law does require class voting where the transaction involves an amendment to the
certificate of incorporation which would increase or decrease the aggregate
number of authorized shares of the class, increase or decrease the par value of
the shares of the class, or alter or change the powers, preferences or special
rights of the shares of the class so as to affect them adversely.
 
     Thermo.  Thermo's Certificate and By-Laws provide for the simple majority
vote to approve the actions referenced in the first paragraph above and do not
provide for class voting.
 
                                       26
<PAGE>   30
 
     LSI.  LSI's Certificate provides that, in addition to the LSI Required
Vote, so long as any shares of LSI Series 1 Preferred Stock are outstanding, LSI
may not adopt any plan of merger or consolidation or sale of all or
substantially all of its assets without first obtaining the affirmative vote or
written consent of not less that two-thirds of such outstanding shares voting
together as a single class.
 
DISSENTER RIGHTS
 
     Under Delaware Law, a dissenting shareholder of a corporation participating
in certain transactions, under varying circumstances, may receive cash in the
amount of the fair value of his or her shares (as determined by a court) in lieu
of the consideration otherwise receivable in any such transaction. Unless the
certificate of incorporation provides otherwise, under Delaware Law, dissenter
rights are not available with respect to a plan of merger or share exchange or a
proposed sale or exchange of property to holders of shares of any class or
series which, on the record date fixed to determine the shareholders entitled to
vote at the meeting of shareholders at which such action is to be acted upon or
to consent to any such action without a meeting, were (i) registered on a
national securities exchange or designated as a national market system security
on an interdealer quotation system by the National Association of Securities
Dealers, Inc., or (ii) held of record by not fewer than 2,000 shareholders.
Thermo stockholders are therefore not entitled to dissenters rights. In
addition, under Delaware Law, dissenter rights are not available for any shares
of stock of the constituent corporation surviving a merger if the merger did not
require shareholder approval of the surviving corporation, and with respect to
any sale of assets, reclassification of stock or amendment to the certificate of
incorporation. See "Rights of Dissenting Shareholders."
 
     The proposed structure of the Merger will give rise to dissenters rights
under Delaware Law for holders of LSI Capital Stock. To exercise such rights,
stockholders must take certain actions within the time limits prescribed by
Delaware Law. See "Rights of Dissenting Shareholders" and Appendix B to this
Information Statement/Prospectus.
 
ANTI-TAKEOVER STATUTES
 
     Section 203 of the Delaware Law ("Section 203") regulates large
accumulations of shares of public companies, including those made by tender
offers. Section 203 may have the effect of significantly delaying a purchaser's
ability to acquire the entire interest in a company if such acquisition is not
approved by the company's Board of Directors. In general, Section 203 prevents
an "Interested Stockholder" (defined generally as a person with 15% or more of a
corporation's outstanding voting stock) from engaging in a "Business
Combination" (defined below) with a Delaware corporation for three years
following the date such person became an Interested Stockholder. For purposes of
Section 203, the term "Business Combination" includes sales, or other
dispositions to the Interested Stockholder (except proportionately with the
corporation's other shareholders) of assets of the corporation or a subsidiary
equal to 10% or more of the aggregate market value of the corporation's
consolidated assets or its outstanding stock; the issuance or transfer by the
corporation or a subsidiary of stock of the corporation or such subsidiary to
the Interested Stockholder (except for transfers in a conversion or exchange or
a pro rata distribution or certain other transactions, none of which increase
the Interested Stockholder's proportionate ownership of any class or series of
the corporation's or such subsidiary's stock); or receipt by the Interested
Stockholder (except proportionately as a stockholder), directly or indirectly,
of any loans, advances, guarantees, pledges or other financial benefits provided
by or through the corporation or a subsidiary.
 
     The three-year moratorium imposed on Business Combinations by Section 203
does not apply if: (a) prior to the date on which such stockholder becomes an
Interested Stockholder the Board of Directors approves either the Business
Combination or the transaction which resulted in the person becoming an
Interested Stockholder; (b) the Interested Stockholder owns 85% of the
corporation's voting stock upon consummation of the transaction which made him
or her an Interested Stockholder (excluding from the 85% calculation shares
owned by directors who are also officers of the target corporation and shares
held by employee stock plans which do not permit employees to decide
confidentially whether to accept a tender or exchange offer); or (c) on or after
the date such person becomes an Interested Stockholder, the Board
 
                                       27
<PAGE>   31
 
approves the Business Combination and it is also approved at a stockholder
meeting by holders of 66 2/3% of the voting stock not owned by the Interested
Stockholder.
 
     Thermo.  Under Section 203, the restrictions described above do not apply
if, among other things, the corporation's original certificate of incorporation
contains a provision expressly electing not to be governed by Section 203.
Thermo's Certificate does not contain such a provision. Thermo could, at its
option, exclude itself from the coverage of Section 203 by amending its
Certificate or By-Laws at any time to exempt itself from coverage; but a by-law
or charter amendment may not become effective for a period of 12 months after
the amendment is adopted.
 
     LSI.  Section 203 does not apply to LSI because the LSI Capital Stock is
not listed on a national securities exchange, authorized for a quotation system
or held of record by more than 2,000 stockholders.
 
PREEMPTIVE RIGHTS
 
     Delaware Law generally permits a Delaware corporation, in its certificate
of incorporation, to provide its stockholders with the preemptive right to
subscribe to capital stock or securities convertible into stock. Neither the LSI
Certificate nor the Thermo Certificate provide for preemptive rights.
 
DIVIDENDS
 
     Delaware Law provides that a corporation, unless otherwise restricted by
its certificate of incorporation, may declare and pay dividends out of surplus,
or if no surplus exists, out of net profit for the fiscal year in which the
dividend is declared or the preceding fiscal year (provided that the amount of
capital of the corporation following the declaration and payment of the dividend
is not less than the aggregate amount of the capital represented by the issued
and outstanding shares of all classes having preference upon the distribution of
assets). Additionally, Delaware Law provides that, in general, a corporation may
redeem or repurchase its shares only out of surplus.
 
     Thermo.  The Thermo Certificate grants to the Thermo Board of Directors, at
its discretion, the general power to declare dividends upon the capital stock at
any regular or special meeting of such Board; however, Thermo's Board has never
declared or paid such a dividend.
 
     LSI.  LSI By-Laws confer upon the LSI Board of Directors a similar power to
grant dividends. In addition, however, the LSI Certificate provides that the
holders of LSI Series 1 Preferred Stock shall be entitled to receive, when and
as declared by the LSI Board, dividends at the semi-annual rate of $.06 per
share payable in preference and priority to any payment of any dividend on any
other share of LSI Capital Stock. The right to such dividends are not cumulative
and no right accrues to the holders of LSI Series 1 Preferred Stock by reason of
the fact that no dividends are declared or paid. No dividends may be declared or
paid on LSI Common Stock unless (i) a cash dividend of at least $.06 per share
have been declared and paid on the LSI Series 1 Preferred Stock in the two most
recent semi-annual fiscal periods, and (ii) giving effect to payment of any such
dividend the net worth of LSI would be more than the aggregate amount which the
holders of shares of LSI Series 1 Preferred Stock would be entitled to receive
in the event of the liquidation, dissolution or winding up of LSI.
 
     The LSI Board of Directors has never declared or paid a dividend on any
shares of LSI Capital Stock.
 
LIMITATION ON DIRECTOR'S LIABILITY
 
     Section 102 of the Delaware Law allows a Delaware corporation to limit or
eliminate the personal liability of directors to the corporation and its
stockholders for monetary damages for breach of fiduciary duty as a director.
However, this provision excludes any limitation on liability (a) for any breach
of the director's duty of loyalty to the corporation or its stockholders, (b)
for acts or omissions not in good faith or which involved intentional misconduct
or a knowing violation of law, (c) for intentional or negligent payment of
unlawful dividends or stock purchases or redemptions or (d) for any transaction
from which the director derived an improper personal benefit. While this
provision provides directors with protection from awards for monetary damages
for breaches of their duty of care, it does not eliminate such duty.
Accordingly, this provision will
 
                                       28
<PAGE>   32
 
have no effect on the availability of equitable remedies such as an injunction
or rescission based on a director's breach of his duty of care. Finally, this
provision applies to an officer of a corporation only if he is a director of
such corporation and is acting in his capacity as director, and does not apply
to officers of the corporation who are not directors. Both the Thermo
Certificate and the LSI Certificate provide for the limitation of liability
permitted by Section 102.
 
INDEMNIFICATION OF OFFICERS AND DIRECTORS
 
     Section 145 of the Delaware Law permits a Delaware corporation to indemnify
any officer or director who is a party (or is threatened to be made a party) to
any threatened, pending or completed action, suit or proceeding by reason of the
fact that he is or was a director, officer, or employee of the corporation. In
most cases, such indemnification must first be approved by a majority vote of
the directors who were not parties to the action, suit or proceeding, whether or
not constituting a quorum, and may be provided only if and to the extent the
officer or director to be indemnified acted in good faith and in a manner he
reasonably believed to be in (or not opposed to) the best interests of the
corporation. However, to the extent that an officer or director has been
successful on the merits or otherwise in defense of any such action, suit or
proceeding, he must be indemnified against expenses (including attorney's fees)
actually and reasonably incurred by him in connection therewith. Both the Thermo
By-Laws and the LSI By-Laws provide generally for the indemnification of
officers and directors permitted by Section 145.
 
     Thermo.  Thermo's By-Laws provide that Thermo shall indemnify its directors
and officers to the maximum extent permitted by Delaware Law except with respect
to payments and expenses incurred in relation to matters as to which a director
or officer is finally adjudged in an action, suit or proceeding not to have
acted in good faith and in the reasonable belief that his action was in the best
interests of Thermo, or as otherwise prohibited by law.
 
     LSI.  LSI's By-Laws also provide for indemnification of officers and
directors; however, indemnification shall only be authorized upon a
determination made by (a) the LSI Board of Directors by a majority vote of a
quorum consisting of directors who were not parties to the relevant action, suit
or proceeding; or (b) if such a quorum is not obtainable, or, even if
obtainable, if a quorum of disinterested directors so directs, by independent
legal counsel in a written opinion; or (c) by the stockholders that
indemnification is proper in the circumstances because the officer or director
has met the required standard of care.
 
  Loans to Officers and Employees
 
     Delaware Law provides that a corporation may make loans to, or guarantee
the obligations of, or otherwise assist, its officers and other employees and
those of its subsidiaries when such action, in the judgment of the corporation's
board of directors, may reasonably be expected to benefit the corporation. This
provision of Delaware Law applies only to those directors who are also officers
or employees of the corporation or a subsidiary.
 
     Thermo.  As permitted by Delaware Law, Thermo has adopted a program under
which it may make interest-free loans to officers and certain key employees to
enable such employees to purchase Thrmo Common Stock in the open market. See
"Thermo and LSI Managements and Executive Compensation -- Stock Holdings
Assistance Plan."
 
     LSI.  LSI has not adopted a loan program.
 
                     DESCRIPTION OF THERMO'S CAPITAL STOCK
 
     As of November 1, 1996, Thermo had 100,000,000 shares of common stock
authorized for issuance, of which 48,450,000 were issued and outstanding. Each
share of Thermo Common Stock is entitled to pro rata participation in
distributions upon liquidation and to one vote on all matters submitted to a
vote of stockholders. Dividends may be paid to the holders of Common Stock when
and if declared by the Board of Directors out of funds legally available
therefor. Holders of Common Stock have no preemptive or similar
 
                                       29
<PAGE>   33
 
rights. The outstanding shares of Common Stock are, and the shares offered
hereby when issued will be, legally issued, fully paid and nonassessable.
 
     The shares of Thermo Common Stock have noncumulative voting rights, which
means that the holders of more than 50% of the shares voting can elect all the
Directors if they so choose, and in such event, the holders of the remaining
shares cannot elect any Directors. Thermo Instrument Systems Inc., Thermo's
parent company, beneficially owns 45,000,000 shares of Thermo Common Stock,
which represents approximately 93% of the outstanding Thermo Common Stock as of
November 1, 1996, and has the power to elect all of the members of Thermo's
Board of Directors.
 
     Thermo's Certificate of Incorporation contains certain provisions permitted
under the Delaware Law relating to the liability of directors. The provisions
eliminate a director's liability for monetary damages for a breach of fiduciary
duty, except in certain circumstances involving wrongful acts or omissions,
which involve intentional misconduct or a knowing violation of law. Thermo's
Certificate of Incorporation also contains provisions to indemnify the directors
and officers of Thermo to the fullest extent permitted by the Delaware Law.
 
     The transfer agent and registrar for the Thermo common stock is American
Stock Transfer & Trust Company.

                               BUSINESS OF THERMO
 
     Thermo is a worldwide leader in the development, manufacture and marketing
of analytical instruments that utilize a range of optical spectroscopy
techniques. These instruments are used in the quantitative and qualitative
chemical analysis of elements and molecular compounds in a wide variety of
solids, liquids and gases. Thermo's products are used by its customers for
productivity enhancement, research and development, quality control and testing
applications in the environmental testing, chemical, metallurgical, food and
beverage, pharmaceutical and petroleum industries; and by forensic laboratories,
research organizations and educational institutions. Industry sources estimate
that the total worldwide market for Thermo's current optical spectroscopy
instruments is approximately $2.0 billion and Thermo estimates that the market
for optical components, systems and sub-assemblies addressed by its Thermo
Vision subsidiary is approximately $0.5 billion. The total worldwide market for
analytical instruments is estimated to be approximately $11.0 billion. Thermo
believes that growth in the industry is driven primarily by evolving production
quality control standards, demand for higher productivity, increased regulatory
requirements, research and development expenditures by private industry and
governmental entities and by increasing demand in developing countries.
 
     Thermo's products are used for both elemental and molecular analysis, and
are based on several optical spectroscopy techniques, including atomic
absorption (AA), atomic emission (AE), Fourier transform infrared (FT-IR) and
FT-Raman technologies. AA and AE spectrometers are used to identify trace
quantities of elements in solids and liquids based on the atomic spectra that a
sample emits or absorbs when it is excited by an energy source. These
spectrometers are used in a variety of applications, including the measurement
of toxic elements in environmental samples, metals analysis for industrial use
and product quality assurance for food, drug and cosmetic products. FT-IR and
FT-Raman spectrometers are used to determine the molecular composition of
samples by observing how they absorb or emit infrared light. Because FT-IR and
FT-Raman techniques are non-destructive to a sample, they are used in a wide
variety of applications, including forensic applications and quality assurance
and research and development applications in the pharmaceutical, chemical and
semiconductor industries. Through its subsidiary, Thermo Vision Corporation
("Thermo Vision"), Thermo pursues applications of its optical technologies for
cost-effective, application-specific instruments and for components, systems and
subassemblies used in analytical instrumentation and other broader market
applications. In September 1996, Thermo announced its intent to spinout Thermo
Vision through a distribution of all of its outstanding capital stock in the
form of a dividend to Thermo's shareholders. See "-- Lines of Business -- Thermo
Vision Corporation."
 
     Thermo's strategy is to build upon its position in the industry through the
continued development of technologically superior products and through the
development of new markets, applications and customers for its products, while
maintaining the operating principles that have contributed to its success:
innovative technology, efficient manufacturing capabilities and a worldwide
sales and service network. Thermo believes it has built a reputation in the
industry for providing high performance instruments backed by reliable service,
while effectively controlling costs and maximizing operational efficiencies.
Thermo believes that the market for analytical instruments can be expanded by
(i) increasing customer productivity through the development of products and
technologies that permit analytical instruments to be used on-site and on-line
or near-line in industrial and manufacturing settings and (ii) applying its
broad technology base to the development of cost-effective, application-specific
instruments.
 
     As part of its growth strategy, Thermo intends to actively seek the
acquisition of products and technologies that complement and augment its
existing product lines. The analytical instruments industry is highly fragmented
and is estimated to consist of more than 1,000 industry competitors, many of
which focus on small groups of customers, a narrow range of technologies and
applications, or limited geographic areas. Thus, it can often be more cost
effective to target an attractive market segment through the acquisition of
established, smaller, focused providers than through internal product
development. Thermo has completed the acquisition of several complementary
businesses during the past two years. See "-- Acquisitions." Thermo targets
acquisitions that it believes will lead to enhanced profitability through
manufacturing efficiencies, the elimination of lower margin product lines,
enhanced distribution capabilities, the elimination of duplicative functions and
improved market acceptance of the acquired company's products due to affiliation
with Thermo.

LINES OF BUSINESS
 
     Analytical instruments are generally classified by their principal
operating technologies. Thermo's AE and AA spectrometers comprise its elemental
analysis product line, and FT-IR and FT-Raman spectrometers comprise the
Company's molecular analysis product line. Through its Thermo Vision Corporation
("Thermo Vision") subsidiary, Thermo also develops and manufactures
cost-effective application-specific instruments, as well as components, systems
and subassemblies for analytical instruments.
 
  Elemental Analysis -- AE and AA Spectrometers
 
     Thermo produces a range of AE and AA spectrometers that are used to detect
and measure metals and other elements in solid and liquid samples from
ultratrace (parts per billion) to major concentrations. In AE spectrometers, the
samples are excited by an energy source, causing the sample atoms to emit
radiation. The radiation is then dispersed by a grating into its component light
wavelengths, which are detected by a photo multiplier tube or a solid state
detector. Because each element has a characteristic wavelength that acts as a
"fingerprint" for that element, the instrument compares the detected wavelengths
against a library of spectra for identification. The resulting data may then be
stored and manipulated with a personal computer. AE spectrometers use either an
electrical discharge ("arc/spark") or a high frequency inductively coupled
plasma ("ICP") as the energy source. Arc/spark instruments are used primarily
for solid samples and ICP instruments are used for both solid and liquid
samples. ICP instruments can be coupled with a mass spectrometer ("ICP/MS") to
provide better detection limits. In an AA spectrometer, a graphite furnace or
flame is used to heat the sample. The AA spectrometer incorporates a hollow
cathode lamp that contains the element to be measured. Because the hollow
cathode lamp radiates at the same wavelength as the sample atoms, the sample
atoms absorb radiation from the lamp and the detector measures this absorption.
 
     AE and AA spectrometers are distinguished based on sensitivity, speed,
flexibility and cost. The Company's AA spectrometers are sold at prices ranging
from approximately $15,000 to $65,000. While an AA spectrometer, when configured
with a graphite furnace, is capable of highly sensitive analysis, it can only
measure one element at a time and must be adjusted to measure each element. The
Company's AE spectrometers, which range in price from approximately $50,000 to
$150,000, combine ultratrace detection capabilities with the ability to detect
multiple elements simultaneously. While the purchase price for these instruments
is higher than for AA spectrometers, ICP spectrometers are easier to use and the
cost of associated consumables is greatly reduced. Consequently, analytical
instrument customers are increasingly using ICP spectrometers for applications
historically performed by AA spectrometers. An ICP/MS instrument provides parts
per trillion sensitivity, but ranges in price from $150,000 to $250,000, and is
slower than an AE because it cannot measure multiple elements simultaneously.
 
     Thermo's AE and AA instruments are used in a wide variety of applications,
which include testing of environmental samples such as soil and water, food and
drug testing, analysis of blood, urine and animal tissue, and process control
and product quality assurance testing. Thermo sells its products to a wide range
of customers in manufacturing industries such as producers of aircraft,
automobiles and trucks, computers, chemicals, food, pharmaceuticals and primary
metals; service industries such as waste management companies and commercial
testing laboratories; and government and university laboratories.
 
     Thermo derived revenues of $72.9 million, $81.2 million and $112.3 million
from sales of elemental analysis instruments in 1993, 1994 and 1995,
respectively.
 
     In April 1996, Thermo acquired Unicam, a manufacturer of AA and
ultraviolet/visible ("UV/Vis") spectroscopy instruments, from Thermo Instrument.
Thermo believes that this acquisition will increase its product base in AA
spectrometers, as well as its presence in the European market. In addition, in
November 1996, Thermo acquired ARL, a manufacturer of arc/spark instruments used
in elemental solids analysis and wavelength dispersive x-ray fluorescence
instruments, from Thermo Instrument. ARL developed and commercialized the first
commercial grating spectrograph and is now a worldwide supplier of
spectrochemical instrumentation based on arc/spark optical emission spectrometry
and wavelength dispersive x-ray fluorescence ("WDXRF") spectrometry. Arc/spark
spectrometers are used extensively in the metals industries where a precise
determination of metallurgical content is required. WDXRF spectrometers offer
elemental
 
                                       32
<PAGE>   36
 
analysis of a wide variety of materials in a highly precise and generally
nondestructive manner. The technique, which has been available for over 40
years, is widely accepted as a mechanism for achieving high precision for major
element analysis. ARL's product offering is targeted to the simultaneous
detection segment of the market and has traditionally been the technology leader
in this area. See "-- Acquisitions."
 
  Elemental Liquids Analysis
 
     Atomic Emission Spectrometers.  The principal type of AE spectrometer used
for elemental analysis of liquids is the ICP spectrometer, which allows for
simultaneous multi-element testing. The largest users of ICP instruments are
public and private environmental laboratories, which must test for multiple
elements but which have well defined testing objectives. All of these users test
for compliance with applicable environmental regulations, which prescribe the
specific pollutants and concentrations to be tested for. As a result, growth in
the demand for ICP spectrometers is largely a function of the pace and extent of
enactment and enforcement of environmental regulations worldwide. Currently,
growth is concentrated in developing nations while sales have been declining in
the U.S., principally due to consolidation in the environmental industry.
 
     ICP spectrometers are also used in research and development and quality
control applications in a variety of industries, including the chemical,
pharmaceutical, food and beverage and petroleum industries. For example, ICP
spectrometers are used to determine the content of certain elements in food oils
prior to sale.
 
     Thermo believes it is a market and technology leader in ICP spectrometry.
Within the last three years, Thermo has developed the first ultratrace ICP
spectrometer that incorporates a solid state detector and the first combined
optical emission/mass spectrometer. Thermo's TRACE(TM) ICP analyzer is used
primarily for environmental testing. Thermo's IRIS(TM) ICP spectrometer replaces
the photo multiplier tube used in the TRACE with Thermo's charge injection
device ("CID") solid state detector, allowing customers to perform with one
instrument analyses that would previously have required multiple AA and ICP
instruments. In addition, the IRIS incorporates Windows(TM)-based software that
facilitates use of the instrument with relatively minimal training.
 
     Atomic Absorption Spectrometers.  Due to their sensitivity and relative low
cost, AA spectrometers were historically the instrument of choice for
environmental applications. While the market for AA spectrometers is declining
due to advancements in the sensitivity and flexibility of ICP spectrometers, AA
spectrometers are still used for certain well-defined applications. Certain of
the EPA's protocols for the determination of toxic metals in water and wastes
are written for AA spectrometers. In addition to environmental testing, AA
spectrometers are also used in biological testing and for testing in the
agricultural and petroleum industries.
 
     ICP/MS.  When used in tandem with a mass spectrometer, an ICP is capable of
detecting elements at the part per trillion level. This high level of
sensitivity is often required by semiconductor, pharmaceutical and chemical
companies in both research and development and quality control functions. For
example, manufacturers of semiconductors use ICP/MS instruments to increase
manufacturing yield by testing for the presence of trace contaminants that can
destroy the functionality of a chip. In addition, ICP/MS is used in several
environmental applications.
 
     Thermo has recently introduced the second generation of its POEMS(@)
ICP/MS, which incorporates several significant advances, including automated
sample preparation and Windows-based software. In addition, POEMS is the first
ICP/MS instrument to integrate a CID detector, which enhances the flexibility of
the instrument.
 
     In November 1996, Thermo acquired VG Elemental, a manufacturer of ICP/MS
instruments, from Thermo Instrument. VG Elemental's products are utilized in the
environmental, nuclear, semiconductor, biological, metals and chemicals
industries where critical, ultra-trace detection of elements is required. ICP/MS
instruments range in price from $150,000 to $350,000. See "-- Acquisitions."
 
  Elemental Solids Analysis
 
     Arc/spark instruments are used primarily in highly capital intensive
processes such as steel and other primary metal production, foundries that
fabricate raw metals, and production of products such as pipe and
 
                                       33
<PAGE>   37
 
machine parts. Customers in these industries use the arc/spark instrument in
near line quality control as part of the production process. Due to the high
cost of these processes, the minimization of downtime and the maintenance of
quality control are critical. For these reasons, reliability is frequently the
most important feature to an arc/spark user. Thermo believes it has built a
reputation as an industry leader by offering rugged, dependable instruments and
by emphasizing customer service. Sales of arc/spark instruments are tied to the
addition of metal production capacity. Consequently, the principal areas of
growth for this type of instrument are in developing nations, particularly
China, South Korea and Brazil, where the need for new infrastructure is
increasing.
 
     Thermo offers different arc/spark instruments for different applications
and budgets, from a laboratory grade instrument with the capability to analyze
60 different elements to a durable mobile unit for use in small foundries.
Prices for these instruments range from $50,000 to $150,000. A modified version
of the arc/spark spectrometer is used in the analysis of engine oils and fuels
to determine engine wear. Such measurements enable better prediction of engine
failure, help schedule routine maintenance and extend engine life.
 
Molecular Analysis -- FT-IR and FT-Raman Spectrometers
 
     Thermo is among the world's largest manufacturers of molecular analysis
instruments that utilize FT-IR and FT-Raman spectroscopic techniques. Using
these "vibrational" spectroscopic techniques, customers are able to
non-destructively analyze liquids and solids for their molecular composition.
These techniques also permit the analysis of samples in their packaging, which
eliminates much of the time involved with sample preparation.
 
     Thermo's FT-IR and FT-Raman spectrometers are used principally in research
and development and quality control in a variety of industries. Chemical and
pharmaceutical companies use FT-IR and FT-Raman spectrometers for verification,
identification and quantification of chemical materials and mixtures because of
the superior ability of these instruments to provide detailed structural
information. Other applications involve analysis of total petroleum hydrocarbon
content and other contamination in soil and water, and monitoring of industrial
waste streams.
 
     Thermo believes it has built a reputation as a technology leader, and has
pioneered many of the developments of modern FT-IR, including development of the
first commercial analytical FT-IR instruments and sampling technologies,
including infrared microscopy. Thermo has also developed spectral databases for
use in the identification of samples in FT-IR and FT-Raman analysis.
 
     Thermo derived revenues of $86.2 million, $81.2 million and $93.8 million
from sales of molecular analysis instruments in 1993, 1994 and 1995,
respectively.
 
     In April 1996, Thermo acquired Mattson Instruments ("Mattson"), a Madison,
Wisconsin based manufacturer of FT-IR instruments, from Thermo Instrument.
Thermo believes that this acquisition will increase its FT-IR product base,
particularly through the addition of several valuable product lines. See "--
Acquisitions."
 
     FT-IR Spectrometers.  An FT-IR spectrometer utilizes infrared spectroscopy
to obtain precise qualitative and quantitative information regarding the
molecules in a sample. In an infrared ("IR") spectrometer, an infrared beam of
light is directed at a sample, which will absorb certain frequencies and
transmit others unchanged. Because each molecule has a characteristic
"fingerprint" based upon its absorption and transmission characteristics,
molecules can be identified by comparison to a library of spectra. The FT-IR
technique provides quantitative and qualitative information across the entire
infrared spectrum simultaneously, which permits rapid multi-component analysis
without the need for sample separation.
 
     The major advantage of an FT-IR spectrometer is its ability to
non-destructively analyze samples. The ability to preserve the sample is
critical in many applications, including forensics, drug development and
semiconductor analysis. FT-IR spectrometers are also capable of providing
structural information regarding a particular molecule that cannot be provided
by other types of analytical instruments. This type of information is extremely
valuable in chemical and pharmaceutical research and development applications,
where the
 
                                       34
<PAGE>   38
 
structure of the molecule can be as important as the quantification and
identification of the components of a complex sample.
 
     Thermo offers several lines of FT-IR spectrometers that range in
performance and price based upon the needs of its customers. Its FT-IR
spectrometers range in price from approximately $25,000 to $200,000. Thermo
believes the Magna-IR(]) line of spectrometers offers the highest level of
analytical capability available in a FT-IR spectrometer. The Magna-IR is
engineered to be flexible and expandable in order to accommodate all of the
analytical requirements of the most demanding users in the chemical,
pharmaceutical and semiconductor industries and in academic and research
environments. The Magna-IR incorporates the first digital signal
processor-controlled interferometer, which allows the customer greater control
and flexibility in the design of advanced experiments.
 
     Thermo's Impact(]) line of FT-IR spectrometers incorporates many of the
design features of the Magna-IR line in a rugged, reliable, lower cost
instrument. The Impact is generally used for routine measurement by
environmental testing laboratories, law enforcement laboratories, industrial
quality control laboratories and other customers that require reliability,
high-throughput and ease of use but do not need the most advanced analytical
capabilities.
 
     In response to the unique requirements of customers in the semiconductor
industry, Thermo has developed the ECO(]) line of dedicated quality inspection
instruments. This instrument utilizes IR analysis on-line to determine the
physical parameters and uniformity of silicon wafers used in the manufacture of
integrated circuits, memory and application specific devices.
 
     Thermo also offers several lines of infrared microscopes and micro imaging
accessories. Thermo believes it is the leading supplier of infrared microscopes
and micro imaging spectroscopic devices in the world. These products are
utilized, individually or in conjunction with FT-IR spectrometers, to obtain the
infrared spectrum of small samples in the range from 20 to 1000 microns. The
products combine both the function of visual location and imaging with infrared
spectral analysis, thus allowing the user to quickly locate and focus the
infrared probe beam on the exact micro area of interest. The top of the line
Irus product is an integrated system, fully comprising both infrared
spectrometer and microscopic analysis station in one unit.
 
     FT-Raman Spectrometers.  FT-Raman spectroscopy is a technique similar to
FT-IR that utilizes a laser to excite the sample. While FT-IR spectrometers
measure the transmission and absorption characteristics of a sample, FT-Raman
spectrometers measure the emission characteristics of the sample. When the
sample absorbs the energy from the laser beam, a modified wavelength is emitted
by the sample. This emission fingerprint is compared to a library of spectra to
determine molecular structure. Many samples that produce weak or non-specific
responses in the infrared produce strong, unique signatures in the Raman, and
vice versa. As a result the two techniques are highly complementary for many
applications.
 
     Thermo has been responsible for many innovations in FT-Raman spectroscopy,
including the first stand-alone FT-Raman instrument and Windows-driven
spectrometer and the only searchable Raman library in digital format. Thermo's
current line of FT-Raman spectrometers incorporates many of the design features
of its FT-IR spectrometers, while offering certain advantages over FT-IR
spectrometers, including easier sampling and data analysis. Thermo has also
developed an FT-Raman module for use with its Magna-IR spectrometer. FT-Raman
spectrometers are attractive for use in pharmaceutical analysis, remote
monitoring of chemicals and quality assurance of materials within their
packaging because of the transparency of the packaging to the Raman signal. This
capability permits on line analysis of finished products.
 
  Thermo Vision Corporation
 
     Through its subsidiary, Thermo Vision, Thermo pursues applications of its
technologies for cost-effective, application-specific instruments and for
optical components, systems and subassemblies for analytical instrumentation and
other applications. Thermo believes that there is a trend in the market for
analytical instruments toward the development of lower cost instruments that are
easy to use and capable of performing discrete analyses accurately and reliably.
Thermo Vision is also building a sales and service channel for lower
 
                                       35
<PAGE>   39
 
cost instruments and components that cannot be effectively or profitably sold or
serviced through the channels used for larger, higher performance analytical
instruments.
 
     As part of its strategy, Thermo Vision is pursuing various applications for
Thermo's CID solid state optical detectors. Thermo acquired rights to the CID
technology through its acquisition of CID Technologies Inc. in October 1994.
Thermo believes that the CID detector has several advantages over other solid
state detectors. Like CCDs (charge coupled devices) currently used in most
consumer products, CIDs use multiple electronic pixels to capture images.
However, unlike CCDs, CIDs are capable of randomly accessing the individual
pixels, which improves the speed and quality of imaging and permits pixels to be
read non-destructively. In addition, CIDs have superior resistance to radiation,
which is an advantage for use in environments such as nuclear power plants.
Thermo Vision is currently under contract to provide the CID detector outside
the analytical instrument field, including dental imaging and nuclear
inspection.
 
     For the year ended December 30, 1995, Thermo derived revenues of $6.1
million from its Thermo Vision businesses.
 
     In February 1996, Thermo Vision acquired Corion Corporation ("Corion"), a
manufacturer of commercial optical filters, for $5.1 million and Oriel
Corporation ("Oriel"), a manufacturer and distributor of electro-optical
instruments and components, for $11.8 million. Corion and Oriel reported
revenues of $8.5 and $18.8 million, respectively, in 1995. The Company believes
that the acquisition of Corion and Oriel will further Thermo Vision's strategic
move into the subassembly and end product markets, including the manufacture of
cost-effective instruments used for a specific purpose. Optical filters, such as
those manufactured by Corion, are a cost-effective method of screening all but a
specific wavelength of interest. Thermo believes that components such as these
will be increasingly important in improving the performance of cost-effective,
targeted systems such as fluorometers and UV/Vis spectrometers. In addition,
Oriel publishes a series of widely distributed catalogues which Thermo believes
will assist in the distribution of many Thermo Vision products, as well as
products offered by other Thermo Optek businesses.
 
     In September 1996, Thermo announced its intent to spinout Thermo Vision
through a distribution of all of its outstanding capital stock in the form of a
dividend to Thermo's shareholders. Thermo anticipates completing the spinout by
the second quarter of 1997, and is seeking a Letter Ruling from the Internal
Revenue Service stating that the proposed spinout will have no current tax
effect on Thermo or its shareholders. Thermo would distribute the shares upon
receipt of the Letter Ruling and satisfaction of other conditions, including
listing of the Thermo Vision shares on the American Stock Exchange. Upon
completion of this proposed transaction, Thermo Vision would be a majority-owned
subsidiary of Thermo Instrument.
 
ACQUISITIONS
 
     An element of Thermo's strategy is to combine its internal growth with the
acquisition of complementary products and technologies. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations of
Thermo." In addition to the acquisitions of Oriel and Corion described above,
recently completed acquisitions by Thermo are described below.
 
     Mattson and Unicam.  In December 1995, Thermo Instrument acquired the
assets of the analytical instruments division of ATI (the "ATI Division"), a
manufacturer of analytical instruments, for $42.5 million. In April 1996, Thermo
acquired the ATI Division's Mattson and Unicam businesses from Thermo Instrument
for an aggregate purchase price of $36.6 million. Mattson is a Wisconsin-based
manufacturer of FT-IR spectroscopy instruments and Unicam is a Cambridge,
UK-based manufacturer of AA and UV/Vis spectroscopy instruments. The purchase
price represents the sum of (i) the net tangible book value of Mattson and
Unicam as of the date of acquisition by Thermo Instrument, plus (ii) a
percentage of the total goodwill associated with Thermo Instrument's acquisition
of the ATI Division equal to sales of Mattson and Unicam for the eleven-month
period ended November 30, 1995 relative to total sales of the ATI Division for
such period. Mattson and Unicam reported aggregate revenues of approximately
$57.8 million for the eleven months ended November 30, 1995.
 
                                       36
<PAGE>   40
 
     Mattson's FT-IR products are primarily used in high through-put
applications requiring certified and validated methods and automation, such as
quality assurance and control and educational markets. Prices for Mattson's
products range from $20,000 to $60,000.
 
     Unicam's AA product line covers a complete range of applications, from
cost-effective systems to high-capability ultimate detection capacity systems,
and are well-suited to environmental, clinical and industrial chemical analyses.
These products offer a higher degree of automation than that offered by
comparable competitive products. All of Unicam's AA products utilize
Windows-based operating software, with product prices ranging from $18,000 to
$80,000.
 
     Unicam also manufactures UV/Vis spectrometers. A UV/Vis spectrometer
utilizes ultra-violet and visible light to obtain precise qualitative and
quantitative information regarding the molecules in a sample. In UV/Vis
spectrometers, a beam of light, either ultra-violet or visible, is directed at a
sample, which absorbs certain frequencies and transmit others unchanged. Because
each molecule has characteristic absorption and transmission features, both
quantitative and qualitative measurements can be made. The UV/Vis permits rapid
multi-component analysis without the need for sample separation. Unicam's
systems range from low-end non-scanning products priced at under $4,000 to a
mid-range scanning series priced at $24,000. These products are targeted at
teaching laboratories, life science research, pharmaceutical and environmental
markets. Thermo believes that Unicam's UV/Vis products will complement its other
products and presence in the environmental, life science research,
pharmaceutical and chemical markets.
 
     ARL and VG Elemental.  In March 1996, Thermo Instrument completed the
acquisition of a substantial portion of the businesses comprising the scientific
instruments division of Fisons (the "Fisons Division"). In November 1996, Thermo
acquired the Fisons Division's ARL and VG Elemental businesses, and four
associated sales organizations located in South Africa, Austria, Sweden and
Canada, from Thermo Instrument for an aggregate purchase price of $55.2 million
in cash and the assumption of $16.6 million in debt, subject to a post-closing
adjustment. ARL is a Switzerland-based manufacturer of arc/spark AE
spectrometers and X-ray fluorescence instruments. ARL had revenues of
approximately $55.7 million in 1995. VG Elemental is a U.K.-based manufacturer
of inductively coupled plasma/mass spectromers. VG Elemental, located near
Manchester, England, introduced its first ICP/MS instrument in 1984. ICP/MS
instruments are used for environmental, nuclear, semiconductor, biological,
metals and chemical analysis where critical, ultra-trace detection of elements
is required. VG Elemental had revenues of $16.2 million in 1995. The purchase
price paid by Thermo for these businesses represents the sum of (i) the net
tangible book value of ARL and VG Elemental as of the date of acquisition by
Thermo Instrument, plus (ii) a percentage of the total goodwill associated with
Thermo Instrument's acquisition of the acquired portions of the Fisons Division
equal to sales of ARL and VG Elemental relative to total sales of the portion of
the Fisons Division acquired by Thermo Instrument.
 
     Certain of the businesses recently acquired by Thermo or which Thermo
expects to acquire in the future have low levels of profitability or are
unprofitable. No assurance can be given that Thermo will be successful in
reducing expenses and improving operations of these businesses so that the
levels of profitability desired by Thermo are achieved. Thermo expects that its
operating margins will be reduced due to the acquisition of these recently
acquired businesses until such time as it has improved the profitability of
these businesses to levels comparable with those of Thermo's other businesses.
See "Management's Discussion and Analysis of Financial Condition and Results of
Operations of Thermo."
 
RESEARCH AND DEVELOPMENT
 
     Thermo maintains active programs for the development of new technologies
and the enhancement of existing products. In addition, Thermo seeks to develop
new applications for its products and technologies. Research and development
expenses for Thermo were $10.6 million, $10.5 million and $13.0 million in 1993,
1994 and 1995, respectively, or 6.6%, 6.3% and 6.1%, respectively, of Thermo's
revenues for such periods.
 
     A significant portion of Thermo's development effort is directed toward
developing instruments that can be used outside of the laboratory in industrial
and manufacturing settings such as near line quality control applications.
Thermo believes that developing instruments that can be used by non-scientists
is critical to the
 
                                       37
<PAGE>   41
 
success of this program. Thermo has a Cooperative Research and Development
Agreement (CRADA) with the U.S. Navy to develop an ICP instrument for the
continuous monitoring of heavy metals in smokestack emissions. Thermo will have
the right to use any proprietary technology developed through this agreement.
Through Thermo Vision, Thermo is directing its efforts toward applying Thermo's
technology to the development of affordable application-specific instruments and
cost-effective components, systems and subassemblies. Thermo is also pursuing
various applications of its CID technology, including dental imaging and nuclear
inspection.
 
COMPETITION
 
     Thermo competes in each of its markets primarily on performance,
reliability, customer service and price. In the market for AE and AA
spectrometers and ICP/MS instruments, Thermo competes primarily with
Perkin-Elmer and, to a lesser extent, Varian. Thermo competes in the arc/spark
market primarily with Spectro. In the FT-IR and FT-Raman markets Thermo competes
primarily with Perkin-Elmer, the Digilab division of Bio-Rad, Bruker and Bomem.
Industry sources have estimated that Thermo held the competitive position noted
in parentheses below in 1995 for each of the following markets based on 1995
revenues: AE spectrometers (2), AA spectrometers (3), ICP/MS instruments (4),
arc/spark instruments (2), FT-IR instruments (1) and FT-Raman instruments (2).
Thermo recently entered the market for UV/Vis instruments with its acquisition
of Unicam in April 1996. The primary competitors in this market are Hewlett-
Packard, Perkin-Elmer, Shimadzu and Life Sciences.
 
SALES AND MARKETING
 
     Thermo markets its instruments internationally through its own worldwide
sales force and through a network of dealers and distributors. In addition,
Thermo sells certain components and instruments pursuant to OEM arrangements
under which third parties purchase and resell Thermo's products. Thermo's sales
force is supported throughout the world by a customer support group which
provides training, instrument servicing and parts replacement. Thermo believes
that its sales and distribution channels in the Pacific Rim provide it with a
competitive advantage.
 
BACKLOG
 
     Thermo's backlog was $64.1 million as of September 28, 1996, compared with
$50.1 million as of December 30, 1995. Thermo includes in its backlog only
orders confirmed with a purchase order for products and related services
scheduled to be shipped or rendered within one year. Thermo does not believe
that the level of, or changes in the level of, its backlog is necessarily a
meaningful indication of future results of operations.
 
PATENTS AND LICENSES
 
     Thermo's policy is to protect its intellectual property rights, including
applying for and obtaining patents when appropriate. Thermo holds numerous
patents relating to its technologies, with additional patents pending. Thermo
also enters into licensing agreements with other companies and government
agencies in which it grants or receives rights to specific patents and technical
know-how. Thermo also considers technical know-how, trade secrets and trademarks
to be important to its business.
 
PERSONNEL
 
     As of September 28, 1996, Thermo had a total of 1,883 employees. To date,
Thermo has been able to attract and retain the personnel required by its
business, but there can be no assurance that additional skilled personnel
necessary to successfully expand Thermo's business and operations can be
recruited and retained. Thermo believes that its relationship with employees is
good.
 
FACILITIES
 
     Thermo's various businesses are operated from separate facilities, as set
forth in the table below.

     LEGAL PROCEEDINGS
 
     Prior to Nicolet's acquisition by Thermo, the Wisconsin Department of
Natural Resources ("DNR") notified Nicolet that the DNR had begun a remedial
investigation to determine the extent of releases of hazardous substances from
the Refuse Hideaway Landfill located in Middleton, Wisconsin (the "Landfill"),
and that Nicolet was a potential responsible party ("PRP") with regard to the
Landfill. Approximately 50 other parties were also notified of their potential
PRP status. The Environmental Protection Agency ("EPA") subsequently added the
Landfill to its National Priorities List under the Comprehensive Environmental
Response Compensation and Liability Act of 1980 ("CERCLA"). In February 1995,
the EPA and the DNR recommended that various remediation efforts be made at the
Landfill at an estimated cost of approximately $5.2 million, and Thermo expects
that such agencies will also seek to recover their oversight costs and expenses
related to the site. Under CERCLA, responsible parties can include current and
previous owners of a site, generators of hazardous substances disposed of at a
site, and transporters of hazardous substances to a site. Each responsible party
can be jointly and severally liable, without regard to fault or negligence, for
all costs associated with the remediation of the site. Although Thermo believes
that the quantity of materials generated by Nicolet and transported to the
Landfill is relatively small in comparison to that of other named PRPs, there
can be no assurance as to the exact amount, if any, for which Nicolet will be
held responsible by the EPA and the DNR for costs associated with remediation of
the Landfill.
 
     In connection with the organization of Thermo, Thermo Instrument agreed to
indemnify Thermo for any and all cash damages incurred by Thermo, including with
respect to the Landfill, relating to certain contingent liabilities associated
with the operations of Nicolet and TJA prior to August 1995, when such
businesses were transferred to Thermo. Notwithstanding this indemnification,
Thermo would be required to report any such damages as an expense in its results
of operations, with any indemnification payment it receives from Thermo
Instrument being treated as a contribution to shareholders' investment.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
            FINANCIAL CONDITION AND RESULTS OF OPERATIONS OF THERMO
 
OVERVIEW
 
     Thermo's principal operating units include Thermo Jarrell Ash Corporation
("TJA"), a manufacturer and distributor of atomic absorption and atomic emission
spectrometry products, and Nicolet Instrument Corporation ("Nicolet"), a
manufacturer and distributor of Fourier transform infrared ("FT-IR") and FT-
Raman spectrometry products. Both TJA and Nicolet have worldwide sales and
service organizations with a strong overseas presence in Europe, Japan and
China.
 
     Thermo also has a subsidiary, Thermo Vision, which pursues applications of
Thermo's technologies for cost-effective, application-specific instruments and
for optical components, systems and subassemblies for analytical instrumentation
and other applications. In September 1996, Thermo announced its intent to spin
out Thermo Vision through a distribution of 100 percent of its outstanding
capital stock in the form of a dividend to Thermo's shareholders. Thermo
anticipates completing the spinout by the second quarter of 1997. Thermo intends
to seek a Letter Ruling from the Internal Revenue Service stating that this
proposed spinout would have no current tax effect on Thermo or its shareholders.
Thermo would distribute the shares upon receipt of the Letter Ruling and
satisfaction of other conditions, including listing of the Thermo Vision shares
on the American Stock Exchange. Thermo Vision had revenues of $8.4 million and
$22.6 million for the three- and nine-month periods ended September 28, 1996,
respectively.
 
     Thermo's strategy is to supplement its internal growth with the acquisition
of businesses and technologies that complement and augment its existing product
lines. On December 1, 1995, Thermo Instrument acquired the assets of the
analytical instruments division of Analytical Technology, Inc. ("ATI"). In April
1996, Thermo acquired the Mattson Instruments ("Mattson") and Unicam divisions
of ATI from Thermo Instrument. For accounting purposes, Thermo's acquisition of
Mattson and Unicam is deemed to have occurred on December 1, 1995. Mattson is a
manufacturer of FT-IR spectroscopy instruments, and Unicam is a manufacturer of
AA and ultraviolet/visible spectroscopy instruments. In February 1996, Thermo
acquired Oriel Corporation ("Oriel"), a manufacturer and distributor of
electro-optical instruments and components and Corion Corporation ("Corion"), a
manufacturer of commercial optical filters.
 
     On March 29, 1996, Thermo Instrument acquired a substantial portion of the
businesses comprising the Scientific Instruments Division of Fisons plc
("Fisons"). On November 4, 1996, Thermo acquired two businesses formerly part of
Fisons, Applied Research Laboratories ("ARL") and VG Elemental, from Thermo
Instrument for an aggregate $55.2 million in cash and the assumption of $16.6
million in debt, subject to a post-closing adjustment. For accounting purposes,
Thermo's acquisition of ARL and VG Elemental is deemed to have occurred on March
29, 1996. ARL is a manufacturer of wavelength-dispersive x-ray fluorescence
instruments and arc/spark atomic emission spectrometers and VG Elemental is a
manufacturer of inductively coupled plasma/mass spectrometers. ARL and VG
Elemental had revenues $55.7 million and $16.2 million in 1995, respectively. In
addition to ARL and VG Elemental, Thermo also acquired four sales and service
organizations of these two businesses located in South Africa, Austria, Sweden
and Canada. Thermo anticipates distributing ARL's and VG Elemental's products
elsewhere through Thermo's existing distribution companies.
 
RESULTS OF OPERATIONS
 
  First Nine Months 1996 Compared With First Nine Months 1995
 
     Revenues increased $105.1 million, or 71%, to $253.7 million in the first
nine months of 1996 from $148.6 million in the first nine months of 1995
primarily due to the acquisitions of ARL and VG Elemental, effective March 29,
1996, Mattson and Unicam, effective December 1, 1995, and Oriel and Corion in
February 1996. Acquisitions added revenues of $97.1 million in the first nine
months of 1996. To a lesser extent, revenues increased due to greater product
demand, primarily at Nicolet as a result of two recently introduced products. In
addition, revenues in the third quarter of 1995 were low as a result of a
disruption caused by the relocation of certain TJA operations into a new
facility. These increases were offset in part by a decrease of $5.0 million
 
                                       40
<PAGE>   44
 
in revenues due to the unfavorable effects of currency translation as a result
of the strengthening of the U.S. dollar relative to foreign currencies in
countries where Thermo operates.
 
     The gross profit margin decreased to 47% in the fist nine months of 1996
from 51% in the first nine months of 1995 primarily due to the inclusion of
lower-margin revenues from ARL and VG Elemental. In addition the gross profit
margin was unusually high in 1995 as a result of a decrease in lower-margin
revenues from TJA due to the plant relocation discussed above.
 
     Selling, general and administrative expenses as a percentage of revenues
were unchanged at 29% in the first nine months of 1996 and 1995. Research and
development expenses as a percentage of revenues remained relatively unchanged
at 6.6% in 1996, compared with 6.7% in 1995.
 
     Prior to their acquisitions by Thermo, ARL and VG Elemental sold products
to other business units of the Scientific Instruments Division of Fisons for
marketing and ultimate resale of the customer. Thermo plans to distribute the
products of ARL and VG Elemental primarily through its existing distribution
channels. As a result of this strategy, Thermo expects to increase selling,
general and administrative expenses as a percentage of revenues at these
businesses while improving the gross profit margin to cover these additional
costs. Thermo's goal is to improve the gross profit margin at ARL and VG
Elemental through this change in distribution channels as well as through
improving product mix and manufacturing efficiencies, although there can be no
assurance that Thermo will be successful in these efforts.
 
     Interest income increased to $4.3 million in the first nine months of 1996
from $72,000 in the first nine months of 1995 primarily as a result of interest
income earned on invested proceeds from Thermo's October 1995 issuance of $96.3
million principal amount of 5% subordinated convertible debentures. Interest
expense increased to $5.0 million in 1996 from $1.0 million in 1995 primarily
due to interest on Thermo's 5% subordinated convertible debentures.
 
     The effective tax rate was 42.7% in the first nine months of 1996, compared
with 41.5% in the first nine months of 1995. The effective tax rates exceeded
the statutory federal income tax rate primarily due to nondeductible
amortization of cost in excess of net assets of acquired companies and the
impact of state income taxes. The effective tax rate increased in 1996 from 1995
primarily due to higher nondeductible amortization of cost in excess of net
assets of acquired companies in 1996.
 
  1995 Compared with 1994
 
     Revenues were $212.2 million in 1995, compared with $165.4 million in 1994,
an increase of 28.3%. Revenues increased $25.9 million and $9.2 million due to
the acquisition of Baird in January 1995 and Mattson and Unicam in December
1995, respectively. In addition, revenues from Nicolet increased $10.4 million
due to increased demand for its products, particularly in Japan and the Pacific
Rim and, to a lesser extent, due to currency fluctuations. Overall, revenues
increased $5.7 million in 1995 due to the weakness of the U.S. dollar in
relation to foreign currencies.
 
     The gross profit margin declined to 48.8% in 1995 from 50.3% in 1994. This
decline was primarily due to the inclusion of lower-margin products from Baird
and disruption in operations caused by the consolidation of the manufacturing
operations of Baird and TJA into a new facility in mid-1995. In addition,
increased competition due to the contraction of the environmental market had a
negative impact on the margins of TJA in 1995. The U.S. environmental market has
been consolidating, which has negatively affected sales of several of TJA's
products. The declines at Baird and TJA were offset in part due to improved
margins at Nicolet resulting primarily from the weakness of the U.S. dollar in
relation to foreign currencies, in particular the Japanese yen and German mark,
as well as improved margins for its newly introduced products.
 
     Selling, general and administrative expenses as a percentage of revenues
increased to 29.3% in 1995 from 28.1% in 1994 as a result of higher expenses at
Baird prior to the consolidation of Baird's operations with TJA and expanded
selling efforts in China and Brazil. Research and development expenses as a
percentage of revenues were relatively unchanged at 6.1% in 1995, compared with
6.3% in 1994.
 
                                       41
<PAGE>   45
 
     Interest income increased to $1.5 million in 1995 as a result of interest
income earned on the invested proceeds from Thermo's $96.3 million principal
amount of 5% Convertible Subordinated Debentures. Interest expense increased to
$2.5 million in 1995 from $1.7 million in 1994 primarily due to interest on
these debentures.
 
     The effective tax rate was 41.8% in 1995 and 41.5% in 1994. These rates
exceed the statutory federal income tax rate due to the impact of state income
taxes, nondeductible amortization of cost in excess of net assets of acquired
companies and the inability in 1995 to provide a tax benefit on foreign losses,
offset in part by the tax benefit associated with a foreign sales corporation.
 
  1994 Compared With 1993
 
     Revenues were $165.4 million in 1994, compared with $161.0 million in 1993.
An increase in revenues at TJA due to increased demand, a $4.6 million increase
in revenues due to the acquisitions of Hilger Analytical in July 1993 and CID
Technologies Inc. in October 1994, and a $3.3 million increase in revenues due
to the weakness of the U.S. dollar in relation to foreign currencies were offset
in part by a decline in revenues at Nicolet due to two large orders that were
shipped during 1993.
 
     The gross profit margin declined to 50.3% in 1994 from 52.4% in 1993 due to
lower margins at TJA resulting from changes in product mix and lower margins on
sales in Europe due to the European recession.
 
     Selling, general and administrative expenses as a percentage of revenues
were 28.1% in 1994, compared with 28.4% in 1993. Research and development
expenses as a percentage of revenues remained relatively unchanged at 6.3% in
1994, compared with 6.6% in 1993.
 
     Interest expense declined to $1.7 million in 1994 from $2.2 million in 1993
due to the repayment of borrowings by Nicolet in September 1994 and reduced
working capital borrowings at Thermo's European subsidiaries.
 
     The effective tax rate was 41.5% in 1994, compared with 40.4% in 1993.
These rates exceed the statutory federal income tax rate due primarily to the
impact of state income taxes and the nondeductible amortization of cost in
excess of net assets of acquired companies, offset in part by the tax benefit
associated with a foreign sales corporation.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     Consolidated working capital was $95.8 million at September 28, 1996,
compared with $144.5 million at December 30, 1995. Included in working capital
are cash and cash equivalents of $114.2 million at September 28, 1996, compared
with $116.9 million at December 30, 1995. Cash provided by operating activities
was $21.0 million for the first nine months of 1996. Accounts receivable
decreased by $5.7 million primarily as a result of a reduction in receivables at
ARL and VG Elemental from the date of their acquisition. Accounts payable
decreased $10.2 million due to a payment for inventories received in the fourth
quarter of 1995 and a reduction in payables at ARL and VG Elemental from the
date of their acquisition. Other current liabilities decreased $2.9 million
primarily due to restructuring expenditures at Mattson, Unicam, ARL and VG
Elemental.
 
     On November 4, 1996, Thermo acquired ARL and VG Elemental from Thermo
Instrument for $55.2 million in cash and the assumption of $16.6 million in
debt, subject to a post-closing adjustment to be negotiated with Fisons by
Thermo Instrument in connection with the negotiations for the settlement of the
final purchase price for all of the businesses of Fisons acquired by Thermo
Instrument in March 1996. Thermo has recorded a payable of $55.2 million for the
acquisition of ARL and VG Elemental in the accompanying 1996 balance sheet.
Thermo paid the liability described above to Thermo Instrument on November 4,
1996.
 
     Thermo's investing activities used $56.3 million of cash in the first nine
months of 1996. Thermo expended an aggregate $52.1 million, net of cash
acquired, for acquisitions, including the acquisitions of Mattson and Unicam,
and $4.1 million for the purchase of property, plant and equipment.
 
                                       42
<PAGE>   46
 
     Thermo's financing activities provided $33.0 million of cash in the first
nine months of 1996. In June and July 1996, Thermo sold 3,450,000 shares of its
common stock in an initial public offering for net proceeds of approximately
$42.9 million. During the first nine months of 1996, Thermo repaid $10.0 million
of short- and long-term borrowings.
 
     During the remainder of 1996, Thermo plans to make expenditures of
approximately $1.5 million for property, plant and equipment. Although Thermo
expects positive cash flow from its existing operations, Thermo anticipates it
will require significant amounts of cash to pursue the acquisition of
complementary businesses. Thermo expects that it will finance acquisitions
through a combination of internal funds, additional debt or equity financing
from the capital markets, or short-term borrowings from Thermo Instrument or
Thermo Electron, although there is no agreement with Thermo Instrument or Thermo
Electron under which such parties are obligated to lend funds to Thermo. Thermo
believes that its existing resources are sufficient to meet the capital
requirements of its existing businesses for the foreseeable future.

                                BUSINESS OF LSI
 
     LSI designs, manufactures and markets pulsed nitrogen, dye and pulsed
carbon dioxide (CO(2)) lasers. These products have applications in industry,
medicine, education and defense. LSI laser products are used for industrial
sensing and measurement, environmental monitoring and biomedical diagnostics.
 
PRODUCTS
 
     LSI's nitrogen lasers use nitrogen gas to generate pulsed light. The light
produced by a nitrogen laser is ultraviolet, which interacts strongly with many
materials. This interaction makes the nitrogen laser a valuable component of
many measurement and detraction systems. The LSI nitrogen laser line consists of
unusually compact, reliable, simple and easy to maintain products. The power of
the nitrogen laser can also be used to cause many dyes to act as lasers
themselves. These lasers can be tuned to output a wide variety of colors of
light.
 
     Actual applications of these products include laser induced fluorescence (a
technique for chemical analysis), time of flight mass spectrometry,
spectroscopy, environmental monitoring, calibration of photomultiplier tubes
(devices for light measurement), biochemical analysis, cellular ablation (used
for surgery within a single cell) cellular microscopy and remote excitation via
fiberoptics.
 
     LSI also offers a line of CO(2) lasers. CO(2) lasers create light in the
infrared, which is very effective at transferring energy via heat. CO(2) lasers
can deliver much higher power levels than nitrogen lasers. The CO(2) lasers
produced by LSI also deliver pulsed light. They are also compact and very
rugged. Many specific models are offered, including a miniature CO(2) laser for
specific spectroscopy and metrology applications, and custom designs are
manufactured to meet the needs of the individual researcher. The pulsed CO(2)
lasers are used for environmental monitoring, far-infrared generation,
nondestructive testing, laser spectroscopy, laser radar and Doppler laser radar.
 
COMPETITION
 
  Nitrogen and Tunable Dye Lasers
 
     LSI believes it holds a dominant position in these markets because of its
technical leadership, as well as the performance and reliability of its lasers.
Competition is particularly intense in the research and development market,
where laser quality is not as critical as with instrument manufacturers. Oriel
Corporation (a subsidiary of Thermo) and Laser Photonics also sell nitrogen
lasers in the U.S.
 
  Pulsed CO(2) Lasers
 
     LSI believes its product offerings in this market are unique due to a
combination of high data rate and excellent light quality. In addition, LSI's
systems engineering capability has allowed it to offer integrated systems with
both laser transmitter and return light detection. Competition in the commercial
markets for air quality measurement are from other (non-laser) techniques and
from lasers that operate at different wavelengths.
 
SALES AND MARKETING
 
     LSI sells its products directly to customers both within the United States
and to original equipment manufacture ("OEM") accounts worldwide. Sales to OEM
accounts represented approximately 60% of total sales during fiscal 1996. In
addition, LSI utilizes sales representatives in Europe, Japan and Korea. Sales
outside the United States accounted for approximately 33% of LSI's total sales
during fiscal 1996.
 
PERSONNEL
 
     LSI has 29 full time employees as of November 1, 1996. The employees are
not represented by a union and LSI believes its employee relations to be
satisfactory.

FACILITIES
 
     LSI conducts its operations from a 12,500 square foot facility located at
75 Chapel Street, Newton, Massachusetts, under a lease which expires in
February, 1997. If the Merger is consummated, it is anticipated that the
operations of LSI will be moved to Thermo's Franklin, Massachusetts facility
after the expiration of LSI's lease. See "Business of Thermo -- Facilities."
 
LEGAL PROCEEDINGS
 
     To LSI's knowledge, there are no pending legal proceedings which are
material to LSI to which it is a party or to which any of its property is
subject.
 
TRANSACTIONS BETWEEN THERMO AND LSI
 
     During the fiscal year ended June 30, 1996, LSI sold products to Thermo
Bioanalysis Corporation, an affiliate of Thermo, in an aggregate amount of
approximately $236,000. These sales were made on a purchase order basis, without
a formal contract.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
              FINANCIAL CONDITION AND RESULTS OF OPERATIONS OF LSI
 
BUSINESS OPERATIONS
 
     LSI designs and manufactures nitrogen, tunable dye and pulsed CO(2)
Transversely Excited Atmospheric ("TEA") lasers for sale to a diverse worldwide
customer base. LSI was incorporated in 1981.
 
     LSI's VSL nitrogen lasers and companion tunable dye laser modules are built
to be affordable, compact, and very easy to use. The nitrogen lasers are totally
self contained, require no external gas supplies, and use a unique disposable
sealed plasma cartridge that can be replaced in minutes. Pre-aligned resonator
optics eliminate the need for tedious alignment.
 
     Researchers, educators, and instrument manufacturers use the VSL series of
lasers for laser-induced fluorescence, time-of-flight mass spectrometry,
spectroscopy, environmental monitoring, calibration of photo multiplier tubes,
biochemical analysis, cell ablation, cellular microscopy, and remote excitation
via fiberoptics.
 
     LSI's PRF series of pulsed CO(2) TEA lasers are built to be compact,
rugged, and reliable. The laser head is separate from the power supply, so PRF
lasers take up less lab space and are easily transported to field applications.
All PRF lasers provide high repetition rates. Specific models are available for
wavelength agility, active frequency control, or sealed-off operation.
 
     Researchers use PRF lasers for environmental monitoring, FT-IR generation,
nondestructive testing, laser spectroscopy, remote sensing, differential
scattering/differential absorption LIDAR, coherent or direct detection, and
Doppler lidar. PRF lasers are also an ideal source for harmonic generation to 5
um.
 
     The PRF series includes the u-TEA mini pulsed CO(2) laser for spectroscopy
and detector calibration applications and the PRF-150WAL wavelength agile laser
for environmental monitoring.
 
THREE MONTHS ENDED SEPTEMBER 30, 1996 COMPARED WITH THREE MONTHS ENDED SEPTEMBER
30, 1995
 
     Net sales for the three months ended September 30, 1996, as compared with
the three months ended September 30, 1995, increased 13% to $821,000 from
$728,000. The increase is primarily attributable to a general increase in VSL
nitrogen laser sales caused by increased demand for these products.
 
     The gross profit margin for the three months ended September 30, 1996, as
compared with the three months ended September 30, 1995, decreased to 32% from
35%. The decrease was principally attributable to an increase in raw material
costs for the VSL product line.
 
     Operating expenses for the three months ended September 30, 1996, as
compared with the three months ended September 30, 1995, decreased 14% to
$320,000 from $372,000. The decrease was principally due to a decrease in
compensation and related payroll costs of approximately $50,000 attributable to
management's decision not to fill certain positions that were vacated during
1996.
 
YEAR ENDED JUNE 30, 1996 COMPARED WITH YEAR ENDED JUNE 30, 1995
 
     Net sales for fiscal 1996, as compared with fiscal 1995, increased 10% to
$4,044,000 from $3,687,000. The increase in net sales is primarily attributable
to a general increase in VSL nitrogen laser sales caused by increased demand for
these products.
 
     The gross profit margin for the year ended June 30, 1996, as compared with
the year ended June 30, 1995, increased to 42% from 31%. The increase was
principally attributable to a change in personnel functions. During fiscal 1995,
a number of employees were involved in production relating to a significant
contract which was completed during that year. In fiscal 1996, certain of these
employees were transferred from production to research and development
activities.
 
     Operating expenses for the year ended June 30, 1996, as compared with the
year ended June 30, 1995, increased 56% to $1,542,000 from $987,000. The
increase was principally due to an increase in research and development expenses
of $343,000 related to the transfer of additional employees to research and
development activities and an increase in commission and other direct selling
costs of approximately $70,000 directly related to the increase in net sales.
 
                                       46
<PAGE>   50
 
     Interest income for fiscal 1996, as compared with fiscal 1995, decreased to
$2,000 from $11,000. Interest income for fiscal 1995 was higher due to an
increase in funds available for investment resulting from a substantial cash
advance received from a customer in 1994. Miscellaneous income for fiscal 1996,
as compared with fiscal 1995, increased to $23,000 from $6,000, primarily as a
result of a gain on sale of machinery of $12,000 during fiscal year 1996.
 
     The effective income tax rate was 24% for the year ended June 30, 1996, as
compared with 9% for the year ended June 30, 1995. The effective tax rate for
fiscal year 1996 included $22,931 for an increase in the deferred income tax
valuation allowance (Note 12 of Notes to Financial Statements of LSI). The
effective tax rates differ from the statutory federal income tax rate primarily
due to the impact of the utilization of net operating loss carryovers and state
income taxes.
 
YEAR ENDED JUNE 30, 1995 COMPARED WITH YEAR ENDED JUNE 30, 1994
 
     Net sales for fiscal 1995, as compared with fiscal 1994, increased 6% to
$3,687,000 from $3,494,000. The increase in net sales is principally
attributable to a change in sales mix as a result of higher demand for VSL
nitrogen lasers and lower demand for LSI's CO(2) TEA product.
 
     The gross profit margin for the year ended June 30, 1995, as compared with
the year ended June 30, 1994, remained relatively constant at 31% and 32%,
respectively.
 
     Operating expenses for the year ended June 30, 1995, as compared with the
year ended June 30, 1994, increased 14% to $987,000 from $865,000. The increase
was principally due to an increase in compensation and related payroll costs of
$151,000, relating to the addition of a scientist and a new business development
marketing person at the beginning of fiscal 1995.
 
     Interest expense for fiscal 1995, as compared with fiscal 1994, decreased
to $11,000 from $28,000. The decrease was primarily due to lower average
line-of-credit borrowings resulting from a substantial cash advance received
from a customer in 1994. Miscellaneous income for fiscal 1995, as compared with
fiscal 1994, decreased to $6,000 from $36,000, primarily as a result of debt
forgiveness of $20,000 during fiscal year 1994.
 
     The effective income tax rate for the year ended June 30, 1995, as compared
with the year ended June 30, 1994, decreased to 9% from 43%. The effective tax
rate for fiscal year 1994 included $79,078 for an increase in the deferred
income tax valuation allowance arising from adoption of an accounting
pronouncement (Note 12 of Notes to Financial Statements of LSI). The effective
tax rates differ from the statutory federal income tax rate primarily due to the
impact of the utilization of net operating loss carryovers and state income
taxes.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     Working capital at September 30, 1996 was $641,000, compared with $692,000
at June 30, 1996. Included in working capital was cash of $20,000 at September
30, 1996, compared with cash of $95,000 as of June 30, 1996. Cash used in
operations for the three month period ended September 30, 1996 was $50,000.
Collections of accounts receivable were offset by increases in inventories and
the payment of accrued liabilities.
 
     LSI has a revolving bank line of credit agreement for $300,000. Borrowings
under the line of credit agreement have been minimal during the fiscal years
ending June 30, 1996 and 1995.
 
     LSI currently anticipates that it will generate sufficient cash flow from
operations to meet its present and reasonably foreseeable capital needs.
 
ACCOUNTING POLICIES
 
     In March, 1995, SFAS No. 121, "Accounting for the Impairment of Long-Lived
Assets and for Long-Lived Assets to Be Disposed Of" was released. SFAS No. 121
became effective for LSI for the fiscal year ending June 30, 1997. The effect of
adoption is not material to LSI's financial statements.

COMPENSATION OF DIRECTORS
 
     Commencing January 1, 1996, Directors who are not employees of Thermo,
Thermo Instrument or Thermo Electron receive an annual retainer of $4,000 and a
fee of $1,000 per day for attending meetings of the Board of Directors and $500
per day for participating in meetings of the Board of Directors held by means of
conference telephone and for participating in certain meetings of committees of
the Board of Directors. Payment of Directors fees is made quarterly.
 
     Dr. G. Hatsopoulos and Messrs. J. Hatsopoulos, Lewis and Smith are all
employees of Thermo Electron companies and do not receive any cash compensation
from Thermo for their services as Directors. Directors are also reimbursed for
reasonable out-of-pocket expenses incurred in attending such meetings.
 
     Directors Deferred Compensation Plan.  Under Thermo's Deferred Compensation
Plan for Directors (the "Deferred Compensation Plan"), a Director has the right
to defer receipt of his fees until he ceases to serve as a Director, dies or
retires from his principal occupation. In the event of a change in control or
proposed change in control of Thermo that is not approved by the Board of
Directors, deferred amounts become payable immediately. Either of the following
is deemed to be a change of control: (a) the occurrence, without the prior
approval of the Board of Directors, of the acquisition, directly or indirectly,
by any person of 50% or more of the outstanding Thermo Common Stock or the
outstanding common stock of Thermo Electron; or (b) the failure of the persons
serving on the Board of Directors immediately prior to any contested election of
directors or any exchange offer or tender offer for the Thermo Common Stock or
the common stock of Thermo Electron to constitute a majority of the Board of
Directors at any time within two years following any such event. Amounts
deferred pursuant to the Deferred Compensation Plan are valued at the end of
each quarter as units of Common Stock. When payable, amounts deferred may be
disbursed solely in shares of Common Stock accumulated under the Deferred
Compensation Plan. Thermo has reserved 75,000 shares under this plan. As of
September 28, 1996, a total of 253 full shares had been accumulated under this
plan.
 
     Directors Stock Option Plan.  Thermo has adopted a directors stock option
plan (the "Plan") providing for the grant of stock options to purchase shares of
the Thermo Common Stock to outside Directors (Directors who are not employees of
Thermo or any of its affiliates) as additional compensation for their service as
Directors. The Plan provides for the grant of stock options upon a Director's
initial appointment and, beginning in 2000, awards options to purchase 1,000
shares annually to eligible Directors, provided Thermo's Common Stock is then
publicly traded. A total of 225,000 shares of Thermo Common Stock have been
reserved for issuance under the Plan.
 
     Under the Plan, each eligible Director and each new outside Director
initially joining the Board of Directors in 1996 will be granted an option to
purchase 45,000 shares of Thermo Common Stock upon the Director's appointment or
election. The size of the award to new Directors appointed to the Board of
Directors after 1996 will be reduced by 11,250 shares in each subsequent year.
Directors initially joining the Board of Directors after 1999 would not receive
an option grant upon their appointment or election to the Board of Directors,
but would be eligible to participate in the annual option awards described
below. Options evidencing initial grants to Directors are presently exercisable,
however, the shares acquired upon exercise are subject to restrictions on
transfer and the right of Thermo to repurchase such shares at the exercise price
in the event the Director ceases to serve as a Director of Thermo or any other
Thermo Electron company. In such event, the restrictions and repurchase rights
shall lapse or be deemed to have lapsed in equal annual installments of 11,250
shares, starting with the first anniversary of the grant date, provided the
Director has continuously served as a Director of Thermo or any other Thermo
Electron company since the grant date. These options expire on the fifth
anniversary of the grant date, unless the Director dies or otherwise ceases to
serve as a Director of Thermo or any other Thermo Electron company prior to that
date.
 
     Commencing in 2000, eligible Directors will also receive an annual grant of
options to purchase 1,000 shares of Thermo Common Stock provided the Thermo
Common Stock is then publicly traded. The annual grant would be made at the
close of business on the date of each annual meeting of stockholders of Thermo
to each Director then holding office, commencing with the annual meeting to be
held in 2000. Options evidencing annual grants may be exercised at any time from
and after the six-month anniversary of the grant
 
                                       50
<PAGE>   54
 
date of the option and prior to the expiration of the option on the third
anniversary of the grant date. Shares acquired upon exercise of the options
would be subject to repurchase by Thermo at the exercise price if the recipient
ceased to serve as a Director of Thermo or any other Thermo Electron company
prior to the first anniversary of the grant date.
 
     The exercise price for options granted under the Plan is determined by the
average of the closing prices reported by the American Stock Exchange (or other
principal exchange in which the Thermo Common Stock is then traded) for the five
trading days immediately preceding and including the date the option is granted
or, if the shares underlying the option are not so traded, at the last price
paid per share by independent investors in an arms-length transaction with
Thermo prior to the option grant.
 
     As of November 1, 1996, 90,000 options to purchase Thermo Common Stock had
been granted under the Plan at an exercise price of $13.50 per share.

  Summary Compensation Table
 
     The following table summarizes compensation for services to Thermo in all
capacities awarded to, earned by or paid to Thermo's chief executive officer and

(1) All options to purchase shares of the Thermo Common Stock shown in the table
    were granted after the end of fiscal 1995 but are included in the table for
    clarity of presentation. In addition to grants of options to purchase Thermo
    Common Stock (designated in the table as TOC), Dr. Rosenthal has been
    granted options to purchase common stock of Thermo Electron and certain of
    its other subsidiaries as part of Thermo Electron's stock option program.
    Options have been granted during the last fiscal year to Dr. Rosenthal in
    the following Thermo Electron companies: Thermo Electron (designated in the
    table as TMO) and Thermo BioAnalysis Corporation (designated in the table as
    TBA). In addition, Mr. Lewis has been granted options to purchase common
    stock of Thermo Electron and certain of its subsidiaries other than Thermo.
    These options are not reported here as they were granted as compensation for
    service to Thermo Electron companies in capacities other than in his
    capacity as Chief Executive Officer of Thermo.

(3) Mr. Lewis is an Executive Vice President and Chief Operating Officer of
    Thermo Instrument as well as the President and Chief Executive Officer of
    Thermo. Reported in the table under "Annual Compensation" and "All Other
    Compensation" are the total amounts paid to Mr. Lewis for his service in all
    capacities to Thermo Electron companies. The Human Resources Committee of
    the Board of Directors of Thermo reviewed total annual compensation to be
    paid to Mr. Lewis from all sources within the Thermo Electron organization
    and approves the allocation of a percentage of annual compensation (salary
    and bonus) for the time he devotes to the affairs of Thermo. For 1995, 85%
    of Mr. Lewis' annual compensation was allocated to Thermo. In addition, Mr.
    Lewis has been granted options to purchase common stock of Thermo Electron
    and certain of its subsidiaries other than Thermo from time to time by
    Thermo Electron or such other subsidiaries. These options are not reported
    here as they were granted as compensation for service to Thermo Electron
    companies in capacities other than in his capacity as Chief Executive
    Officer of Thermo.
 
(4) Options to purchase shares of the common stock of Thermo Electron reflect a
    three-for-two stock split effected in the form of a 50% stock dividend on
    June 5, 1996.

(1) All options to purchase shares of the Thermo Common Stock (designated in the
    table as TOC) were granted after the end of fiscal 1995 but are included in
    the table for clarity of presentation. Options to purchase shares of the
    common stock of Thermo BioAnalysis Corporation (designated in the table as
    TBA) and of Thermo Electron (designated in the table as TMO) were granted in
    1995 to Dr. Rosenthal. The options to purchase shares of the Thermo Common
    Stock and the common stock of Thermo Electron are immediately exercisable,
    while the options to purchase shares of the common stock of Thermo
    BioAnalysis Corporation are not exercisable until December 17, 1996 (90 days
    after the effective date of the registration of that company's Common Stock
    under Section 12 of the Securities Exchange Act of 1934). In all cases, the
    shares acquired upon exercise are subject to repurchase by the granting
    corporation at the exercise price if the optionee ceases to be employed by
    such corporation or another Thermo Electron company. The granting
    corporation may exercise its repurchase rights within six months after the
    termination of the optionee's employment. For publicly traded companies, the
    repurchase rights generally lapse ratably over a five- to ten-year period,
    depending on the option term which may vary from seven to twelve years,
    provided that the optionee continues to be employed by the granting
    corporation or another Thermo Electron company. For companies that are not
    publicly traded, the repurchase rights lapse in their entirety on the ninth
    anniversary of the grant date. The granting
 
                                       52
<PAGE>   56
 
    corporation may permit the holders of all such options to exercise options
    and satisfy tax withholding obligations by surrendering shares equal in fair
    market value to the exercise price or withholding obligation. Information
    with respect to options to purchase the common stock of Thermo Electron
    reflects three-for-two stock splits effected in May 1995 and June 1996.
 
(2) The amounts shown on this table represent hypothetical gains that could be
    achieved for the respective options if exercised at the end of the option
    term. These gains are based on assumed rates of stock appreciation of 5% and
    10%, compounded annually from the date the respective options were granted
    to their expiration date. The gains shown are net of the option exercise
    price, but do not include deductions for taxes or other expenses associated
    with the exercise. Actual gains, if any, on stock option exercises will
    depend on the future performance of the Thermo Common Stock, the
    optionholders' continued employment through the option period and the date
    on which the options are exercised.
 
(3) Mr. Lewis has been granted options to purchase shares of the common stock of
    Thermo Electron and its subsidiaries other than Thermo. These options are
    not reported in the table as they were granted as compensation for service
    in capacities other than Mr. Lewis' capacity as President and Chief
    Executive Officer of Thermo.
 
(4) These options (a) were granted under a stock option plan maintained by
    Thermo Electron and accordingly are reported as a percentage of total
    options granted to employees of Thermo Electron and its subsidiaries and (b)
    reflect a three-for-two stock split of the common stock of Thermo Electron
    effected in the form of a 50% stock dividend on June 5, 1996.

(1) All options to purchase shares of the Thermo Common Stock were granted after
    the end of fiscal 1995 but are included in the table for clarity of
    presentation. All of the options reported outstanding at the end of the
    fiscal year were immediately exercisable, except for options to purchase
    shares of the Thermo Common Stock, which became exercisable 90 days after
    the effective date of the Company's initial public offering of Common Stock,
    and options to purchase shares of the common stock of Thermo BioAnalysis,
    which are not exercisable until December 17, 1996 (90 days after the
    effective date of the registration of that company's common stock under
    Section 12 of the Securities Exchange Act). In all cases, the shares
    acquired upon exercise of the options reported in the table are subject to
    repurchase by the granting corporation at the exercise price if the optionee
    ceases to be employed by such corporation or another Thermo Electron
    company. The granting corporation may exercise its repurchase rights within
    six months after the termination of the optionee's employment. For companies
    whose shares are not publicly traded, the repurchase rights lapse in their
    entirety on the ninth anniversary of the grant date. For
 
                                       53
<PAGE>   57
 
    publicly traded companies, the repurchase rights generally lapse ratably
    over a five- to ten-year period, depending on the option term which may vary
    from seven to twelve years, provided that the optionee continues to be
    employed by the granting corporation or another Thermo Electron company.
    Information with respect to options to purchase the common stock of Thermo
    Electron reflects three-for-two stock splits effected in the form of 50%
    stock dividends on May 1995 and June 1996.
 
(2) Mr. Lewis has been granted options to purchase shares of the common stock of
    Thermo Electron and its subsidiaries other than Thermo. Activity with regard
    to these options is not reported here as they were granted as compensation
    for service in capacities other than in Mr. Lewis' capacity as President and
    Chief Executive Officer of Thermo.
 
(3) Options to purchase 15,750 shares of the common stock of Thermo Electron
    granted to Dr. Rosenthal are subject to the same terms as described in
    footnote (1), except that the repurchase rights of the granting corporation
    generally do not lapse until the tenth anniversary of the grant date. In the
    event of the optionee's death or involuntary termination prior to the tenth
    anniversary of the grant date, the repurchase rights of the granting
    corporation shall be deemed to have lapsed ratably over a five-year period
    commencing with the fifth anniversary of the grant date. Options to purchase
    shares of the common stock of Thermo Electron reflect a three-for-two stock
    split effected in the form of a 50% stock dividend on June 5, 1996.
 
(4) Prior to April 1, 1994, when Ms. Langdon was named President of Thermo
    Vision, she was granted options to purchase shares of the common stock of
    Thermo Electron and its subsidiaries other than Thermo. These options are
    not reported here as they were granted as compensation for service to other
    Thermo Electron companies other than in Ms. Langdon's capacity as a Vice
    President of Thermo.
 
(5) No public market existed for the shares underlying these options as of
    December 30, 1995. Accordingly, no value in excess of exercise price has
    been attributed to these options.
 
  Stock Holdings Assistance Plan
 
     Thermo has adopted a program under which it may make interest-free loans to
certain key employees, including certain of the named executive officers, to
enable such employees to purchase Thermo Common Stock in the open market. During
1996, Mr. Lewis received a loan in the principal amount of $194,030 under this
program.

                  RELATIONSHIP OF THERMO WITH THERMO ELECTRON
                             AND THERMO INSTRUMENT
 
     Thermo was organized in August 1995 as a wholly owned subsidiary of Thermo
Instrument. Thermo Instrument has contributed all of the assets, liabilities and
business of Nicolet and TJA to Thermo in exchange for 45,000,000 shares of
Thermo Common Stock. Thermo Electron holds $10 million principal amount of
Thermo's 5% Convertible Subordinated Debentures.
 
     Thermo Electron has adopted a strategy of selling minority interest in
subsidiary companies to outside investors as an important tool in its future
development. As part of this strategy, Thermo Electron and certain of its
subsidiaries have created publicly and/or privately held majority owned
subsidiaries. (Thermo and the other Thermo Electron subsidiaries are hereinafter
referred to as the "Thermo Subsidiaries.")
 
     Thermo Instrument develops, manufactures and markets instruments used to
detect and monitor air pollution, radioactivity, complex chemical compounds,
toxic metals and other elements in a broad range of liquids and solids. For its
fiscal year ended December 30, 1995 and for the nine months ended September 28,
1996, Thermo Instrument had consolidated revenues of $782,662,000 and
$862,415,000, respectively, and consolidated net income of $79,306,000 and
$99,860,000, respectively.
 
     Thermo Electron and its subsidiaries develop, manufacture and market
environmental monitoring and analysis instruments and manufacture biomedical
products including heart-assist devices and mammography systems, paper-recycling
and papermaking equipment, alternative-energy systems, industrial process
equipment and other specialized products. Thermo Electron and its subsidiaries
also provide environmental and metallurgical services and conduct advanced
technology research and development. For its fiscal year ended December 30, 1995
and for the nine months ended September 28, 1996, Thermo Electron had
consolidated revenues of $2,207,417,000 and $2,138,125,000, respectively, and
consolidated net income of $140,080,000 and $137,184,000, respectively.
 
THE THERMO ELECTRON CORPORATE CHARTER
 
     Thermo Electron and each of the Thermo Subsidiaries recognize that the
benefits and support that derive from their affiliation are essential elements
of their individual performance. Accordingly, Thermo Electron and each of the
Thermo Subsidiaries have adopted the Thermo Electron Corporate Charter (the
"Charter") to define the relationships and delineate the nature of such
cooperation among themselves. The purpose of the Charter is to ensure that (1)
all of the companies and their stockholders are treated consistently and fairly,
(2) the scope and nature of the cooperation among the companies, and each
company's responsibilities, are adequately defined, (3) each company has access
to the combined resources and financial, managerial and technological strengths
of the others, and (4) Thermo Electron and the Thermo Subsidiaries, in the
aggregate, are able to obtain the most favorable terms from outside parties.
 
     To achieve these ends, the Charter identifies the general principles to be
followed by the companies, addresses the role and responsibilities of the
management of each company, provides for the sharing of group resources by the
companies and provides for centralized administrative, banking and credit
services to be performed by Thermo Electron. The services provided by Thermo
Electron include collecting and managing cash generated by members, coordinating
the access of Thermo Electron and the Thermo Subsidiaries (the "Thermo Group")
to external financing sources, ensuring compliance with external financial
covenants and internal financial policies, assisting in the formulation of
long-range financial planning and providing other banking and credit services.
Pursuant to the Charter, Thermo Electron may also provide guarantees of debt or
other obligations of the Thermo Subsidiaries or may obtain external financing at
the parent level for the benefit of the Thermo Subsidiaries. In certain
instances, the Thermo Subsidiaries may provide credit support to, or on behalf
of, the consolidated entity or may obtain financing directly from external
financing sources. Under the Charter, Thermo Electron is responsible for
determining that the Thermo Group remains in compliance with all covenants
imposed by external financing sources, including covenants related to borrowings
of Thermo Electron or other members of the Thermo Group, and for apportioning
such constraints within the Thermo Group. In addition, Thermo Electron
establishes certain internal policies and procedures applicable to members of
the Thermo Group. The cost of the services provided by Thermo Electron to the
Thermo Subsidiaries is covered under existing corporate services agreements
between Thermo Electron and each of the Thermo Subsidiaries.
 
                                       59
<PAGE>   63
 
     The Charter presently provides that it shall continue in effect so long as
Thermo Electron and at least one Thermo Subsidiary participate. The Charter may
be amended at any time by agreement of the participants. Any Thermo Subsidiary,
including the Corporation, can withdraw from participation in the Charter upon
30 days' prior notice. In addition, Thermo Electron may terminate a subsidiary's
participation in the Charter in the event the subsidiary ceases to be controlled
by Thermo Electron or ceases to comply with the Charter or the policies and
procedures applicable to the Thermo Group. A withdrawal from the Charter
automatically terminates the corporate services agreement and tax allocation
agreement (if any) in effect between the withdrawing company and Thermo
Electron. The withdrawal from participation does not terminate outstanding
commitments to third parties made by the withdrawing company, or by Thermo
Electron or other members of the Thermo Group, prior to the withdrawal. However,
a withdrawing company is required to continue to comply with all policies and
procedures applicable to the Thermo Group and to provide certain administrative
functions mandated by Thermo Electron so long as the withdrawing company is
controlled by or affiliated with Thermo Electron.
 
CORPORATE SERVICES AGREEMENT
 
     As provided in the Charter, Thermo and Thermo Electron have entered into a
Corporate Services Agreement (the "Services Agreement") under which Thermo
Electron's corporate staff provides certain administrative services, including
certain legal advice and services, risk management, employee benefit
administration, tax advice and preparation of tax returns, centralized cash
management and financial and other services. In 1993, 1994 and 1995, Thermo
Electron assessed Thermo an annual fee for these services equal to 1.25%, 1.25%
and 1.20%, respectively, of Thermo's revenues. Effective January 1, 1996, the
fee has been reduced to 1.0% of Thermo's revenues. The fee may be changed by
mutual agreement of Thermo and Thermo Electron. During fiscal 1994 and 1995,
Thermo Electron assessed Thermo $2,067,000 and $2,546,000, respectively, in fees
under the Services Agreement. Management believes that the charges under the
Services Agreement are reasonable and that the terms of the Services Agreement
are representative of the expenses Thermo would have incurred on a stand-alone
basis. For additional items such as employee benefit plans, insurance coverage
and other identifiable costs, Thermo Electron charges Thermo based on charges
attributable to it. The Services Agreement automatically renews for successive
one-year terms, unless canceled by Thermo upon 30 days' prior notice. In
addition, the Services Agreement terminates automatically in the event Thermo
ceases to be a member of the Thermo Group or ceases to be a participant in the
Charter. In the event of a termination of the Services Agreement, Thermo will be
required to pay a termination fee equal to the fee that was paid by it for
services under the Services Agreement for the nine-month period prior to
termination. Following termination, Thermo Electron may provide certain
administrative services on an as-requested basis by Thermo or as required in
order to meet Thermo's obligations under Thermo Electron's policies and
procedures. Thermo Electron will charge Thermo a fee equal to the market rate
for comparable services if such services are provided to such subsidiary
following termination.
 
TAX ALLOCATION AGREEMENT
 
     The Tax Allocation Agreement between Thermo and Thermo Electron outlines
the terms under which Thermo is to be included in Thermo Electron's consolidated
Federal and state income tax returns. Under current law, Thermo will be included
in such tax returns so long as Thermo Electron owns at least 80% of the
outstanding common stock of Thermo Instrument and Thermo Instrument owns at
least 80% of the outstanding Thermo Common Stock. In years in which Thermo has
taxable income, it will pay to Thermo Electron amounts comparable to the taxes
Thermo would have paid if it had filed its own separate company tax returns. If
Thermo Instrument's equity ownership of Thermo were to drop below 80%, Thermo
would file its own tax returns.
 
MASTER GUARANTEE REIMBURSEMENT AGREEMENTS
 
     Thermo has entered into a Master Guarantee Reimbursement Agreement with
Thermo Electron which provides that Thermo will reimburse Thermo Electron for
any costs it incurs in the event it is required to pay third parties pursuant to
any guarantees it issues on Thermo's behalf. Thermo Instrument has entered into
a similar agreement with Thermo Electron pursuant to which Thermo Instrument has
guaranteed Thermo's
 
                                       60
<PAGE>   64
 
obligation to so reimburse Thermo Electron. Thermo has also entered into a
Master Guarantee Reimbursement Agreement with Thermo Instrument which provides
that Thermo will reimburse Thermo Instrument for any costs it incurs in the
event that Thermo Instrument is required to pay Thermo Electron or any other
party pursuant to any guarantees Thermo Instrument issues on Thermo's behalf.
 
RELATED PARTY TRANSACTIONS
 
     Thermo purchases and sells products in the ordinary course of business with
other companies affiliated with Thermo Electron. In 1995, purchases and sales of
products to such affiliated companies totalled $1,720,000 and $5,280,000,
respectively.
 
     In October 1995, Thermo Electron purchased $10,000,000 principal amount of
the Debentures, at par and on terms identical to those offered to unaffiliated
investors.
 
     Thermo has recently acquired certain businesses from Thermo Instrument. See
"Business of Thermo -- Acquisitions".
 
     In connection with its recent acquisition of a substantial portion of the
businesses comprising the scientific instruments division of Fisons plc, Thermo
Instrument may restructure certain sales and service activities of the acquired
businesses. This restructuring may include closure of certain existing sales and
service offices and the termination of certain employees engaged in these
activities or the transfer of such employees to various subsidiaries of Thermo
Instrument, including Thermo. Costs associated with any such closures,
terminations and transfers would be allocated to the relevant Thermo Instrument
subsidiary. Thermo does not expect its share of any such costs to materially
affect its future results of operations or liquidity.
 
     Thermo has adopted a program under which it may make interest-free loans to
certain key employees to enable such employees to purchase Thermo Common Stock
in the open market. During 1996, Earl Lewis, President and Chief Executive
Officer of Thermo, received a loan in the principal amount of $194,030 under
this program.
 
MISCELLANEOUS
 
     Thermo's cash equivalents are invested in a repurchase agreement with
Thermo Electron, pursuant to which Thermo in effect lends cash to Thermo
Electron, which Thermo Electron collateralizes with investments principally
consisting of corporate notes, United States government agency securities, money
market funds, commercial paper, and other marketable securities, in the amount
of at least 103% of such obligation. Thermo's funds subject to the repurchase
agreement are readily convertible into cash by Thermo and have an original
maturity of three months or less. The repurchase agreement earns a rate based on
the 90-day Commercial Paper Composite Rate plus 25 basis points, set at the
beginning of each quarter. See Note 1 to Consolidated Financial Statements of
Thermo.
 
                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
     The following is a summary of the principal federal income tax consequences
of the Merger and is based upon the applicable provisions of the Code,
regulations thereunder, and published rulings and court decisions. Neither LSI
nor Thermo intend to seek a ruling from the Internal Revenue Service with regard
to the tax consequences of the Merger.
 
     LSI and Thermo have received an opinion from Hutchins, Wheeler & Dittmar,
counsel for LSI, that under present law, and based upon the representations
contained in the representation letter provided to such counsel by LSI, the
Merger and the conversion of each share of LSI Common Stock into Thermo Common
Stock should have the following consequences for federal income tax purposes:
 
          1. The Merger will qualify as a "reorganization" as defined in Code
     Sections 368(a)(1)(A) and 368(a)(2)(E).
 
          2. No gain or loss will be recognized by LSI as a result of the
     Merger.
 
                                       61
<PAGE>   65
 
          3. No gain or loss will be recognized by LSI shareholders who exchange
     all of their LSI Capital Stock solely for Thermo Common Stock in the
     Merger. Shareholders who exercise dissenters' rights will recognize gain or
     loss upon the receipt of cash for their shares measured by the difference
     between the cash received and the basis of their stock, provided they own
     no shares of Thermo Common Stock.
 
          4. The aggregate basis of the Thermo Common Stock received by a LSI
     shareholder will be the same as the aggregate basis of such shareholder in
     the LSI Capital Stock converted in the Merger.
 
          5. The holding period of the Thermo Common Stock received by a LSI
     shareholder will include the period during which such shareholder held the
     LSI Capital Stock converted in the Merger, provided that such stock was
     held as a capital asset on the Effective Time.
 
          6. An LSI shareholder who receives a cash payment in lieu of a
     fractional share of Thermo Common Stock will be treated as if such
     fractional share were distributed in the Merger and then redeemed by
     Thermo, and should recognize capital gain or loss measured by the
     difference between the amount of cash received and the shareholder's basis
     in the fractional share (which will be a pro rata portion of the
     shareholder's basis in the Thermo Common Stock received in the Merger),
     provided that such shareholder's LSI Capital Stock is held as a capital
     asset at the Effective Time.
 
     In order for the Merger to qualify as a tax-free reorganization, the LSI
shareholders must have the requisite "continuity of interest" through ownership
of the Thermo Common Stock. It is the ruling position of the Internal Revenue
Service that the "continuity of interest" requirement is satisfied if there is a
continuing interest through stock ownership in the acquiring corporation on the
part of the former shareholders of the acquired corporation, without any plan or
intention by the former shareholders of the acquired corporation to sell,
exchange or otherwise dispose of stock of the acquiring corporation, that is
equal in value, as of the Effective Time of the reorganization, to at least 50%
of the value of all the formerly outstanding stock of the acquired corporation
as of the same date. Hutchins, Wheeler & Dittmar has concluded, as part of their
opinion, that the "continuity of interest" requirement will be satisfied in
connection with the Merger. There can be no assurance, however, that the former
shareholders of LSI will not, pursuant to a present plan or intention, sell or
otherwise dispose of the Thermo Common Stock in a sufficient amount to violate
this requirement.
 
     It is a condition to Thermo's obligation to consummate the Merger that all
LSI Options be exercised or cancelled prior to the Effective Time. In the event
that an individual exercised an LSI Option that qualified as an incentive stock
option ("ISO") under the Code, then in order to preserve treatment of the stock
acquired upon the exercise of such ISO, the individual must not make a
disposition of the stock acquired upon such exercise within two years from the
date of the grant of the ISO, nor within one year after the transfer of the
stock to the individual. The receipt of Thermo Common Stock in a transaction
qualified as a tax-free reorganization under the Code would not be treated as a
"disposition" for the one-year and two-year rules discussed above. If, however,
it was determined that the Merger was not a tax-free reorganization, then the
exchange of LSI Common Stock for Thermo Common Stock would be a taxable
disposition and a "disqualifying disposition." Gain on a "disqualifying
disposition" would not be eligible for ISO treatment, and would therefore be
taxed as ordinary income.
 
     Holders of LSI Capital Stock are urged to consult with their tax advisers
as to the effect under state, local and foreign income and other tax laws of the
Merger.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Thermo Optek Corporation:
 
     We have audited the accompanying consolidated balance sheets of Thermo
Optek Corporation (a Delaware corporation and 93%-owned subsidiary of Thermo
Instrument Systems Inc.) and subsidiaries as of December 31, 1994 and December
30, 1995, and the related consolidated statements of income, cash flows and
shareholder's investment for each of the three years in the period ended
December 30, 1995. These consolidated financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these consolidated financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the consolidated financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Thermo Optek
Corporation and subsidiaries as of December 31, 1994 and December 30, 1995 and
the results of their operations and their cash flows for each of the three years
in the period ended December 30, 1995, in conformity with generally accepted
accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1.  NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Nature of Operations
 
     Thermo Optek Corporation (the "Company") develops, manufactures and markets
analytical instruments that utilize a range of optical spectroscopy techniques.
The Company's products are used by its customers for productivity enhancement,
research and development, quality control and testing applications in the
environmental testing, chemical, metallurgical, food and beverage,
pharmaceutical and petroleum industries; and by forensic laboratories, research
organizations and educational institutions.
 
  Relationship with Thermo Instrument Systems Inc. and Thermo Electron
Corporation
 
     The Company was incorporated in August 1995 as a wholly owned subsidiary of
Thermo Instrument Systems Inc. ("Thermo Instrument"). After the formation of the
Company, Thermo Instrument transferred to the Company all of the assets,
liabilities and businesses of Nicolet Instrument Corporation ("Nicolet") and
Thermo Jarrell Ash Corporation ("TJA") in exchange for 45,000,000 shares of the
Company's common stock. As of December 30, 1995, Thermo Instrument was an
86%-owned subsidiary of Thermo Electron Corporation ("Thermo Electron").
 
     The accompanying financial statements include the assets, liabilities,
income and expenses of the Company as included in Thermo Instrument's
consolidated financial statements. The accompanying financial statements do not
include Thermo Instrument's general corporate debt, which is used to finance
operations of all of its respective business segments, or an allocation of
Thermo Instrument's interest expense. The Company has had positive cash flows
from operations since 1993.
 
  Principles of Consolidation
 
     The accompanying financial statements include the accounts of the Company
and its wholly owned subsidiaries. All material intercompany accounts and
transactions have been eliminated.
 
  Fiscal Year
 
     The Company has adopted a fiscal year ending the Saturday nearest December
31. References to 1993, 1994 and 1995 are for the fiscal years ended January 1,
1994, December 31, 1994 and December 30, 1995, respectively.
 
  Revenue Recognition
 
     The Company recognizes revenues upon shipment of its products and
recognizes service contract revenues ratably over the term of the contract. The
Company provides a reserve for its estimate of warranty and installation costs
at the time of shipment. Deferred revenue in the accompanying balance sheets
consists primarily of unearned revenue on service contracts. Substantially all
of the deferred revenue included in the accompanying 1995 balance sheet will be
recognized within one year.
 
  Income Taxes
 
     The Company and Thermo Instrument have a tax allocation agreement under
which both the Company and Thermo Instrument are included in Thermo Electron's
consolidated federal and certain state income tax returns. The agreement
provides that in years in which the Company has taxable income, it will pay to
Thermo Electron amounts comparable to the taxes the Company would have paid if
it had filed separate tax returns. If Thermo Instrument's equity ownership of
the Company were to drop below 80%, the Company would be required to file its
own income tax returns.
 
     In accordance with Statement of Financial Accounting Standards ("SFAS") No.
109, "Accounting for Income Taxes," the Company recognizes deferred income taxes
based on the expected future tax consequences of differences between the
financial statement basis and the tax basis of assets and liabilities,
 
                                       F-7

                            THERMO OPTEK CORPORATION
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
calculated using enacted tax rates in effect for the year in which the
differences are expected to be reflected in the tax return.
 
  Earnings per Share
 
     Pursuant to Securities and Exchange Commission requirements, earnings per
share have been presented for all periods. Weighted average shares for such
periods include the 45,000,000 shares issued to Thermo Instrument in connection
with the initial capitalization of the Company and the effect of the assumed
exercise of stock options issued within one year prior to the Company's initial
public offering. Fully diluted earnings per share have not been presented
because the assumed conversion of the Company's subordinated convertible
debentures would be antidilutive.
 
  Cash and Cash Equivalents
 
     Prior to its incorporation, the cash receipts and disbursements of the
Company's domestic operations were combined with other Thermo Instrument
corporate cash transactions and balances. Therefore, cash of the Company's
domestic operations is not included in the accompanying 1994 balance sheet.
 
     As of December 30, 1995, $106,055,000 of the Company's cash equivalents
were invested in a repurchase agreement with Thermo Electron. Under this
agreement, the Company in effect lends excess cash to Thermo Electron, which
Thermo Electron collateralizes with investments principally consisting of U.S.
government agency securities, corporate notes, commercial paper, money market
funds and other marketable securities, in the amount of at least 103% of such
obligation. The Company's funds subject to the repurchase agreement are readily
convertible into cash by the Company and have an original maturity of three
months or less. The repurchase agreement earns a rate based on the 90-day
Commercial Paper Composite Rate plus 25 basis points, set at the beginning of
each quarter. As of December 30, 1995, the Company's cash equivalents also
include investments in commercial paper and short-term certificates of deposit
of the Company's foreign operations, which have an original maturity of three
months or less. Cash equivalents are carried at cost, which approximates market
value.
 
  Inventories
 
<TABLE>
     Inventories are stated at the lower of cost (on a first-in, first-out or
weighted average basis) or market value and include materials, labor and
manufacturing overhead. The components of inventories are as follows:

</TABLE>
 
  Patents and Other Assets
 
     Patents and other assets in the accompanying balance sheets include the
costs of acquired patents that are amortized using the straight-line method over
their estimated useful lives, which range from 12 to 13 years. These assets were
$9,721,000 and $8,592,000, net of accumulated amortization of $3,704,000 and
$4,833,000, at year-end 1994 and 1995, respectively. Patents and other assets in
the accompanying balance sheets also include deferred debt costs of $2,254,000,
net of accumulated amortization of $102,000, at year-end 1995. Deferred debt
costs are being amortized through the maturity of the related debt, which occurs
in 2000.
 
  Cost in Excess of Net Assets of Acquired Companies
 
     The excess of cost over the fair value of net assets of acquired companies
is amortized using the straight-line method over 40 years. Accumulated
amortization was $6,173,000 and $8,932,000 at year-end 1994 and 1995,
respectively. The Company assesses the future useful life of this asset whenever
events or changes in circumstances indicate that the current useful life has
diminished. The Company considers the future undiscounted cash flows of the
acquired companies in assessing the recoverability of this asset.
 
  Environmental Liabilities
 
     The Company accrues for costs associated with the remediation of
environmental pollution when it is probable that a liability has been incurred
and the Company's proportionate share of the amount can be reasonably estimated.
Any recorded liabilities have not been discounted.
 
  Foreign Currency
 
     All assets and liabilities of the Company's foreign subsidiaries are
translated at year-end exchange rates, and revenues and expenses are translated
at average exchange rates for the year in accordance with SFAS No. 52, "Foreign
Currency Translation." Resulting translation adjustments are reflected as a
separate component of shareholder's investment titled "Cumulative translation
adjustment." Foreign currency transaction gains and losses are included in the
accompanying statement of income and are not material for the three years
presented.
 
  Fair Value of Financial Instruments
 
     The Company's financial instruments consist primarily of cash and cash
equivalents, accounts receivable, notes payable and current maturities of
long-term obligations, accounts payable, due to parent company and

long-term obligations. The carrying amounts of the Company's cash and cash
equivalents, accounts receivable, notes payable and current maturities of
long-term obligations, accounts payable and due to parent company approximate
fair value due to their short-term nature. See Note 9 for fair value information
pertaining to the Company's long-term obligations.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Stock Split
 
     On April 11, 1996, the Company declared a three-for-two stock split in the
form of a 50% stock dividend distributed to the shareholder of record as of
April 11, 1996. All share and per share information has been restated to reflect
the stock split.
 
  Interim Financial Statements
 
     The financial statements as of September 28, 1996 and for the nine-month
periods ended September 30, 1995 and September 28, 1996 are unaudited but, in
the opinion of management, reflect all adjustments of a normal, recurring nature
necessary for a fair presentation of results for these interim periods. The
results of operations for the nine-month period ended September 28, 1996 are not
necessarily indicative of the results to be expected for the entire year.
 
2.  ACQUISITIONS
 
     On January 1, 1995, TJA acquired the Analytical Instruments Division of
Baird Corporation ("Baird"), a wholly owned subsidiary of IMO Industries Inc.,
for $12.9 million in cash. Baird is a manufacturer of arc/spark and other
spectrometers. The acquisition of Baird has been accounted for using the
purchase method of accounting, and its results of operations have been included
in the accompanying financial statements from the date of acquisition.
 
     On December 1, 1995, Thermo Instrument acquired the assets of the
analytical instruments division of Analytical Technology, Inc. ("ATI"). On April
11, 1996, the Company acquired the Mattson Instruments ("Mattson") and Unicam
divisions of ATI from Thermo Instrument for $36.6 million in cash. Mattson is a
manufacturer of Fourier transform infrared ("FT-IR") spectroscopy instruments
and Unicam is a manufacturer of atomic absorption and ultraviolet/visible
spectroscopy instruments. Because, as of December 30, 1995, the Company, Mattson
and Unicam were deemed for accounting purposes to be under control of their
common owner, Thermo Instrument, the accompanying 1995 historical financial
information includes the results of operations of Mattson and Unicam from
December 1, 1995, the date these businesses were acquired by Thermo Instrument.
Because the Company had not disbursed the funds in connection with the
acquisitions of Mattson and Unicam as of December 30, 1995, the transfer of
these businesses has been reflected as a contribution of capital in excess of
par value as of December 1, 1995. The $36.6 million payment from the Company to
Thermo Instrument was accounted for as a reduction of capital in excess of par
value as of April 11, 1996.
 
     The cost of the acquisitions of Baird, Mattson and Unicam exceeded the
estimated fair value of the acquired net assets by $53.8 million, which is being
amortized over 40 years. Allocation of the purchase price for these acquisitions
was based on estimates of the fair value of the net assets acquired and, for
Mattson and Unicam, is subject to adjustment upon finalization of the purchase
price allocation. To date, no information

has been gathered that would cause the Company to believe that the final
allocation of the purchase price will be materially different than the
preliminary estimate.
 
<TABLE>
     Based on unaudited data, the following table presents selected financial
information for the Company, Baird, Mattson and Unicam on a pro forma basis,
assuming the companies had been combined since the beginning of 1994.

</TABLE>
 
     The pro forma results are not necessarily indicative of future operations
or the actual results that would have occurred had the acquisitions of Baird,
Mattson and Unicam been made at the beginning of 1994.
 
     In connection with the acquisitions of Mattson and Unicam, the Company
established reserves totaling $11.6 million for estimated severance, excess
facilities and other exit costs associated with the acquisitions, none of which
was expended during 1995. The Company expects to substantially complete its
review and restructuring of Mattson's and Unicam's operations over the one-year
period following the acquisitions. Any changes in estimates of these costs will
be recorded as adjustments to cost in excess of net assets of acquired
companies. These reserves are included in other accrued expenses in the
accompanying 1995 balance sheet.
 
3.  STOCK-BASED COMPENSATION PLANS
 
     In November 1995, the Company adopted a stock-based compensation plan for
its key employees, directors, and others, which permits the grant of a variety
of stock and stock-based awards as determined by the human resources committee
of the Company's Board of Directors (the "Board Committee"), including
restricted stock, stock options, stock bonus shares or performance-based shares.
To date, only nonqualified stock options have been awarded under this plan. The
option recipients and the terms of options granted under this plan are
determined by the Board Committee. Options granted to date generally vest and
become immediately exercisable on the ninth anniversary of the grant date,
unless the Company's common stock becomes publicly traded prior to such date. In
such an event, options become exercisable 90 days after the Company becomes
subject to the Securities Exchange Act of 1934, but are subject to certain
transfer restrictions and the right of the Company to repurchase shares issued
upon exercise of the options at the exercise price, upon certain events. The
restrictions and repurchase rights generally are deemed to have lapsed ratably
over periods ranging from five to ten years after the first anniversary of the
grant date, depending on the term of the option, which generally ranges from ten
to twelve years. Nonqualified stock options may be granted at any price
determined by the Board Committee, although incentive stock options must be
granted at not less than the fair market value of the Company's stock on the
date of grant. To date, all options have been granted at fair market value. As
of April 11, 1996, options to purchase 2,355,600 shares of the Company's common
stock exercisable at $12.00 per share were outstanding under this plan. As of
April 11, 1996, no options have been exercised and no options are exercisable
under the stock-based compensation plan described above. The Company also has a
directors' stock option plan, adopted in November 1995, that provides for the
grant of stock options to outside directors pursuant to a formula approved by
the Company's shareholders. Options granted under this plan will have the same
general terms as options granted to date under the stock-based compensation plan
described above, except that the restrictions and repurchase rights generally
are deemed to have lapsed ratably over a four-year period and the option term is
five years. As of April 11, 1996, no options to purchase shares of the Company's
common stock have been granted under this plan. In addition to the Company's
stock-based compensation plans, certain officers and key employees may also
participate in the stock-based compensation plans of Thermo Electron or its
majority-owned subsidiaries.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     No accounting recognition is given to options granted at fair market value
until they are exercised. Upon exercise, net proceeds, including tax benefits
realized, are credited to equity.
 
4.  COMMON STOCK
 
     At December 30, 1995, the Company had reserved 9,481,481 unissued shares of
its common stock for possible issuance under stock-based compensation plans and
for issuance upon possible conversion of the Company's subordinated convertible
debentures.
 
5.  EMPLOYEE BENEFIT PLANS
 
  Employee Stock Purchase Plan
 
     Substantially all of the Company's full-time U.S. employees are eligible to
participate in an employee stock purchase plan sponsored by Thermo Instrument.
Prior to the November 1995 plan year, shares of Thermo Instrument's and Thermo
Electron's common stock could be purchased at the end of a 12-month plan year at
85% of the fair market value at the beginning of the plan year, and the shares
purchased were subject to a one-year resale restriction. Effective November 1,
1995, the applicable shares of common stock may be purchased at 95% of the fair
market value at the beginning of the plan year, and the shares purchased are
subject to a six-month resale restriction. Shares are purchased through payroll
deductions of up to 10% of each participating employee's gross wages.
 
  401(k) Savings Plans
 
     Substantially all of the Company's full-time U.S. employees are eligible to
participate in Thermo Electron's or Nicolet's 401(k) savings plans and, prior to
1995, in Thermo Electron's employee stock ownership plan ("ESOP"). Contributions
to the 401(k) savings plans are made by both the employee and the Company.
Company contributions are based upon the level of employee contributions. For
these plans, the Company contributed and charged to expense $967,000, $1,005,000
and $1,106,000 in 1993, 1994 and 1995, respectively. Effective December 31,
1994, the ESOP was split into two plans: ESOP I, covering employees of Thermo
Electron's corporate office and its wholly owned subsidiaries and ESOP II,
covering employees of Thermo Electron's majority-owned subsidiaries. Also,
effective December 31, 1994, the ESOP II plan was terminated and as a result,
the Company's employees are no longer eligible to participate in an ESOP.

     As of November 30, 1995, Unicam had net operating loss carryforwards in the
U.K. of $34,000,000 that are subject to review and adjustment by the U.K. Inland
Revenue Service as a result of the acquisition of the analytical instruments
division of ATI by Thermo Instrument. The Mattson and Unicam divisions also have
net operating loss carryforwards in several other European countries. These
foreign net operating loss carryforwards may only be used to offset taxable
income generated in such European countries.
 
     The year-end 1995 valuation allowance relates to the uncertainty
surrounding the realization of Unicam's foreign net operating loss
carryforwards, the realization of which is limited to the future income of
certain subsidiaries. The net operating loss carryforwards do not expire and any
resulting benefit will be used to reduce cost in excess of net assets of
acquired companies.
 
     A provision has not been made for U.S. or additional foreign taxes on
$7,003,000 of undistributed earnings of foreign subsidiaries that could be
subject to taxation if remitted to the U.S. because the Company plans to keep
these amounts permanently reinvested overseas. The Company believes that any
additional U.S. tax liability due upon remittance of such earnings would be
immaterial due to available U.S. foreign tax credits.
 
7.  COMMITMENTS AND CONTINGENCY
 
  Commitments
 
     The Company leases portions of its office and operating facilities under
various operating lease arrangements. The accompanying statement of income
includes expenses from operating leases of $3,056,000, $2,989,000 and $3,154,000
in 1993, 1994 and 1995, respectively. Future minimum payments due under
noncancellable operating leases at December 30, 1995, are $4,357,000 in 1996;
$3,175,000 in 1997; $2,271,000 in 1998; $1,911,000 in 1999; $1,829,000 in 2000;
and $7,543,000 in 2001 and thereafter. Total future minimum lease payments are
$21,086,000.
 
  Contingency
 
     Prior to Nicolet's acquisition by the Company, the Wisconsin Department of
Natural Resources ("DNR") notified Nicolet that the DNR had begun a remedial
investigation to determine the extent of releases of hazardous substances from
the Refuse Hideaway Landfill located in Middleton, Wisconsin (the "Landfill"),
and that Nicolet was a potential responsible party ("PRP") with regard to the
Landfill. Approximately 50 other parties were also notified of their potential
PRP status. The Environmental Protection

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
Agency ("EPA") subsequently added the Landfill to its National Priorities List
under the Comprehensive Environmental Response Compensation and Liability Act of
1980 ("CERCLA"). In February 1995, the EPA and the DNR recommended that various
remediation efforts be made at the Landfill at an estimated cost of
approximately $5.2 million, and the Company expects that such agencies will also
seek to recover their oversight costs and expenses related to the site. Under
CERCLA, responsible parties can include current and previous owners of a site,
generators of hazardous substances disposed of at a site, and transporters of
hazardous substances to a site. Each responsible party can be jointly and
severally liable, without regard to fault or negligence, for all costs
associated with the remediation of the site. Although the Company believes that
the quantity of materials generated by Nicolet and transported to the Landfill
is relatively small in comparison to that of other named PRPs, there can be no
assurance as to the exact amount, if any, for which Nicolet will be held
responsible by the EPA and the DNR for costs associated with remediation of the
Landfill.
 
     In connection with the organization of the Company, Thermo Instrument
agreed to indemnify the Company for any cash damages resulting from this matter.
Any payments received under such indemnity would be recorded as capital
contributions. In the opinion of management, resolution of this matter will not
have a material adverse effect on the Company's financial position or results of
operations.
 
8.  RELATED PARTY TRANSACTIONS
 
  Corporate Services Agreement
 
     The Company and Thermo Electron have a corporate services agreement under
which Thermo Electron's corporate staff provides certain administrative
services, including certain legal advice and services, risk management, certain
employee benefit administration, tax advice and preparation of tax returns,
centralized cash management, and certain financial and other services, for which
the Company paid Thermo Electron annually an amount equal to 1.25% of the
Company's revenues in 1993 and 1994 and 1.20% of the Company's revenues in 1995.
For these services, the Company was charged $2,013,000, $2,067,000 and
$2,546,000 in 1993, 1994 and 1995, respectively. Beginning in 1996, the Company
will pay an annual fee equal to 1.0% of the Company's revenues. The annual fee
is reviewed and adjusted annually by mutual agreement of the parties. Management
believes that the service fee charged by Thermo Electron is reasonable and that
such fees are representative of the expenses the Company would have incurred on
a stand-alone basis. The corporate services agreement is renewed annually but
can be terminated upon 30 days' prior notice by the Company or upon the
Company's withdrawal from the Thermo Electron Corporate Charter (the Thermo
Electron Corporate Charter defines the relationship among Thermo Electron and
its majority-owned subsidiaries). For additional items such as employee benefit
plans, insurance coverage and other identifiable costs, Thermo Electron charges
the Company based upon costs attributable to the Company.
 
  Other Related Party Services
 
     Prior to 1995, the Company provided certain services to ThermoSpectra
Corporation ("ThermoSpectra"), a majority-owned subsidiary of Thermo Instrument,
and to Nicolet Biomedical Inc. ("Nicolet Biomedical"), a wholly owned subsidiary
of Thermo Electron. The costs of such services were allocated based on the
subsidiaries' revenues attributable to their businesses operated at the
Company's Wisconsin facilities as a percentage of the total revenues of all
businesses operated at such facilities. These services included personnel
administration, accounting, data processing and general administrative
management. For these services, the Company charged $1,543,000 and $672,000 in
1993 and 1994, respectively.
 
  Operating Leases
 
     The Company leases office and manufacturing space to ThermoSpectra and
Nicolet Biomedical pursuant to an arrangement whereby the Company charges
ThermoSpectra and Nicolet Biomedical their allocated

share of the occupancy expenses of the Company's Wisconsin facility, based on
the space ThermoSpectra and Nicolet Biomedical utilize. The Company recorded
operating lease income of $1,305,000, $1,120,000 and $898,000 in 1993, 1994 and
1995, respectively, which is deducted from selling, general and administrative
expenses in the accompanying statement of income. These leases are effective
until December 31, 1998, but may be terminated by ThermoSpectra and Nicolet
Biomedical upon 30 days' prior notice to the Company.
 
  Other Related Party Transactions
 
     The Company purchases and sells products in the ordinary course of business
with other companies affiliated with Thermo Electron. Sales of products to such
affiliated companies totalled $2,642,000, $3,389,000 and $5,280,000 in 1993,
1994 and 1995, respectively. Purchases of products from such affiliated
companies totalled $505,000, $1,555,000 and $1,720,000 in 1993, 1994 and 1995,
respectively.
 
  Repurchase Agreement
 
     The Company invests excess cash in a repurchase agreement with Thermo
Electron as discussed in Note 1.

  Short-term Obligations
 
     Notes payable and current maturities of long-term obligations in the
accompanying balance sheets include $17,005,000 and $17,275,000 in 1994 and
1995, respectively, of short-term bank borrowings by the Company's foreign
subsidiaries. The weighted average interest rates for these borrowings were

     In October 1995, the Company issued and sold $96,250,000 principal amount
of 5% subordinated convertible debentures due 2000. The debentures will be
convertible into shares of the Company's common stock at any time after the
later of (1) 180 days after the date of the closing of the Company's initial
public offering of common stock or (2) the date of the effectiveness under the
Securities Act of 1933 of a registration statement covering the resale of shares
of the Company's common stock issuable upon conversion of the debentures, and
prior to redemption and maturity. The conversion price of the debentures will be
set on the date of the closing of the Company's initial public offering of
common stock and will be equal to 110% of the initial public offering price of
the Company's common stock. If the Company's initial public offering has not
occurred by October 12, 1996, this percentage will decrease by 2.5% on such date
and on each anniversary of such date prior to the Company's initial public
offering. If the Company's initial public offering has not occurred by October
1, 1996, the rate of interest borne by the debentures will increase by 0.5% on
such date

Electron. Thermo Instrument and the Company have agreed to reimburse Thermo
Electron in the event Thermo Electron is required to make a payment under the
guarantee. In addition, the Company has agreed to reimburse Thermo Instrument in
the event Thermo Instrument is required to make a payment under the guarantee.
The fair value of the Company's 5% subordinated convertible debentures was
$100,100,000 as of December 30, 1995. The carrying amount of the Company's other
long-term obligations approximates fair value as of December 30, 1995.

11.  SUBSEQUENT EVENTS
 
  Initial Public Offering
 
     In June and July 1996, the Company sold 3,450,000 shares of its Common
Stock in an initial public offering at $13.50 per share for net proceeds of
approximately $42.9 million. Following the offering, Thermo Instrument owned 93%
of the Company's outstanding common stock.
 
  Acquisitions
 
     On March 29, 1996, Thermo Instruments acquired a substantial portion of the
businesses comprising the Scientific Instruments Division of Fisons plc
(Fisons), a wholly owned subsidiary of Rhone-Poulenc Rorer, Inc. In November
1996, the Company acquired two businesses formerly part of Fisons, A.R.L.
Applied Research Laboratories S.A. (ARL), a manufacturer of arc/spark
instruments used in elemental solids analysis and wavelength dispersive x-ray
fluorescence instruments, and VG Elemental, a manufacturer of inductively
coupled plasma/mass spectrometers, from Thermo Instrument for approximately
$55.2 million in cash and the assumption of $16.6 million in debt, subject to a
post-closing adjustment to be negotiated with Fisons by Thermo Instrument. As of
March 29, 1996, the Company, ARL and VG Elemental were deemed for accounting
purposes to be under control of their common owner, Thermo Instrument, and, as a
result, the accompanying unaudited 1996 financial information includes the
results of operations of ARL and VG Elemental from March 29, 1996. Because the
Company had not disbursed the funds in connection with the acquisition of ARL
and VG Elemental as of September 28, 1996, the purchase price for these
businesses has been recorded as a payable in the accompanying balance sheet.
 
     The cost of the acquisition of ARL and VG Elemental exceeded the estimated
fair value of the acquired net assets by $55.8 million, which is being amortized
over 40 years. Allocation of the purchase price for the acquisition was based on

                          INDEPENDENT AUDITORS' REPORT
 
Board of Directors and Stockholders
Laser Science, Inc.
Newton, Massachusetts
 
     We have audited the accompanying balance sheets of Laser Science, Inc. as
of June 30, 1996 and 1995, and the related statements of operations, changes in
stockholders' equity (deficiency), and cash flows for each of the three years in
the period ended June 30, 1996. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Laser Science, Inc., as of
June 30, 1996 and 1995, and the results of its operations and its cash flows for
each of the three years in the period ended June 30, 1996, in conformity with
generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
 
1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     The Company was incorporated in August, 1981. Its principal business
activities are the development and sale of laser products to a diverse customer
base throughout the world.
 
  Financial Statement Presentation
 
     Certain reclassifications have been made to the 1995 financial statements
in order to conform with the presentation for 1996.
 
  Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and reported amounts of revenues and expenses during the reporting
period. Actual results could differ from those estimates.
 
  Revenue Recognition for Long-Term Contracts
 
     A portion of the Company's revenues are derived from fixed-price contracts.
The Company follows the percentage-of-completion method of accounting for
contracts that extend for periods in excess of one year. Accordingly, revenues
on long-term contracts are recognized in the ratio that costs incurred bear to
estimated total contract costs. Adjustments to cost estimates are made
periodically, and losses expected to be incurred on long-term contracts in
progress are charged to operations in the period such losses are determined.
 
  Fair Value of Financial Instruments
 
     Statements of Financial Accounting Standards No. 107 (SFAS No. 107),
"Disclosures About Fair Value of Financial Instruments", requires disclosure for
the fair value of most on- and off-balance sheet financial instruments for which
it is practicable to estimate that value. The scope of SFAS No. 107 excludes
certain financial instruments, such as trade receivables and payables when the
carrying value approximates the fair value and investments accounted for under
the equity method, and all nonfinancial assets, such as real property. Unless
otherwise described, the fair values of the Company's assets and liabilities
that qualify as financial instruments under SFAS No. 107 approximate the
carrying amounts in the accompanying balance sheet.
 
  Allowances for Doubtful Accounts
 
     The Company has reviewed accounts receivable, trade, as of June 30, 1995
and 1996 and has determined that all amounts are fully collectible. Accordingly,
no allowance for doubtful accounts has been provided for as of June 30, 1995 and
1996.
 
  Inventories
 
     Inventories are valued at the lower of cost or market. Cost is determined
on the first-in, first-out (FIFO) method. Market is based on net realizable
values.
 
  Property and Equipment
 
     Depreciation is computed using the straight-line method calculated to
amortize the cost of the assets over their estimated useful lives. Leasehold
improvements are depreciated using the straight-line method over the lesser of
the term of the related lease or the estimated useful lives of the assets.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  Capital Lease Obligations
 
     Certain long-term lease transactions relating to the financing of property
and equipment are accounted for as installment purchases of equipment. The
capital lease obligations reflect as a liability the present value of future
rental payments and a corresponding amount is capitalized as the cost of the
assets and amortized using the straight-line method over the estimated economic
life of the asset. Depreciation of assets under capital leases is included in
depreciation expense in the accompanying financial statements.
 
  Income Taxes
 
     Income taxes are accounted for in accordance with the provisions of
Statement of Financial Accounting Standards No. 109. The provision for deferred
income tax expense or credit principally represents the net change during the
year in the Company's deferred income tax assets.
 
     Deferred income tax assets represent the amount of taxes recoverable in
future years (based on loss provisions in the current tax laws) resulting from
future net tax deductions arising from temporary differences in the reporting of
certain types of income and expense items for financial statement and for income
tax purposes.
 
  Patent Costs
 
     The costs to obtain patents for certain Company inventions are amortized on
the straight-line method over a seventeen-year period commencing upon approval
of such patents.
 
  Concentrations of Credit Risk
 
     Financial instruments which potentially subject the Company to
concentrations of credit risk consist principally of temporary cash investments.
The Company places its temporary cash investments in high credit financial
institutions. However, balances of temporary cash investments may exceed FDIC
insured levels, from time to time.
 
  Research and Development Costs
 
     The Company's policy is to charge research and development costs to
operations when incurred.
 
  Advertising Costs
 
     The Company charged $60,048, $64,586, and $67,044 for advertising costs to
operations for the years ended June 30, 1994, 1995, and 1996, respectively.
These costs are expensed when incurred.
 
  Interim Financial Statements
 
     The financial statements for the periods ending September 30, 1995 and
1996, are unaudited but, in the opinion of management, reflect all adjustments
of a normal, recurring nature necessary for a fair presentation of results for
this interim period. The results of operations for the three-month period ended
September 30, 1996 are not necessarily indicative of the results to be expected
for the entire year.

</TABLE>
 
     At June 30, 1995 and 1996, inventories reflect a valuation allowance of
$175,000 and $201,045, respectively, necessary to reduce certain inventories to
their estimated net realizable value. It is at least reasonably possible that
this estimate could change in the near term.
 
3.  NOTE PAYABLE, BANKS
 
     At June 30, 1995 and 1996, the Company is indebted under the terms of a
promissory note agreement in the amount of $36,427 and $2,802, respectively.
This agreement requires monthly installments of $2,802 plus interest at the
bank's base rate plus 1.5% per annum through July, 1996. The promissory note
agreement is collateralized by substantially all Company assets.
 
     At June 30, 1994, the Company was indebted under the terms of a bank
promissory note agreement in the amount of $67,250. The balance of this note was
paid in full on July 1, 1995 through a refinancing provided by the bank note
described above.

6.  COMMITMENTS AND CONTINGENT LIABILITIES
 
  Royalty Agreements
 
     The Company has two royalty agreements under which it is required to make
payments based on various percentages of the net selling prices of certain
lasers and laser systems and based on gross sales level for certain lasers. At
June 30, 1995 and 1996, accrued royalties amounted to $58,458 and $58,655,
respectively. Royalty expense under these agreements amounted to $87,936,
$82,616, and $102,930 for the years ended June 30, 1994, 1995, and 1996,
respectively.
 
     During the year ended June 30, 1993, the Company renegotiated one of its
royalty agreements to reduce the total liability under the agreement from
$250,000 to $150,000. The new agreement contains a provision that if the Company
does not meet the payment schedule per the new agreement then the total
liability defaults back to the $250,000. As of June 30, 1996, the Company is in
compliance with the new payment schedule.
 
     The annual minimum fees payable under the royalty agreements as of June 30,
1996 are as follows:

  Lease Commitment
 
     On March 1, 1994, the Company moved its office and operating facility to
Newton, Massachusetts and entered into a lease agreement which expires on
February 28, 1997. Under this lease agreement, the Company is required to pay a
fixed minimum annual rental in equal monthly installments plus electricity
costs. The Company is also responsible for any excess over the base set for
heating, taxes and insurance. Total rent expense incurred under this lease
agreement for the years ended June 30, 1994, 1995, and 1996 amounted to
approximately $80,529, $83,000, and $83,000, respectively.
 
     Future minimum rental payments required under the operating lease as of
June 30, 1996 amount to $51,421.
 
  Line of Credit
 
     The Company has a $300,000 prime plus 1.5% line of credit agreement with a
bank, which is scheduled to be renewed on October 31, 1996. Borrowings under the
agreement are limited to a borrowing base equal to the sum of 70% of eligible
accounts receivable as defined in the agreement. The line of credit is

     The current provision for federal income taxes for the years ended June 30,
1994, 1995 and 1996 was eliminated through the utilization of a net operating
loss carryover.
 
     At June 30, 1996, the Company has available as a potential reduction of
future federal income taxes, a net operating loss carryover of approximately
$4,700,000 expiring in various amounts through the year 2008.

     The provision for income taxes in the accompanying statement of operations
differs from the provision calculated by applying the statutory federal income
tax rate of 34% to income before provision for income taxes due to the

</TABLE>
 
     Certain selling and administrative expenses are capitalized as inventory
costs for income tax purposes while they are expensed for financial statement
purposes.
 
     Inventory allowances for obsolete, slow moving and unsaleable items are
expensed for financial statement purposes in the year the allowance is
established while a deduction cannot be recognized for tax purposes until items
are physically disposed of or sold at a reduced value.
 
     Vacation time is expensed as incurred for financial statement purposes on
an accrual basis while it is expensed as paid for income tax purposes.
 
     As of June 30, 1995 and 1996, the Company has provided a valuation
allowance of 75% and 80% of the future deferred income tax asset related to the
temporary differences and the operating loss carryforward, respectively, because
it is possible that a portion of the tax asset may not be realized. As of June
30, 1995 and 1996, the Company has also provided a valuation allowance of 100%
of the future deferred income tax asset related to research tax credit
carryovers of approximately $190,000 expiring through 2003, because it is
possible that the tax asset may not be realized.
 
     Should there occur a 50% "ownership change" of the Company as defined under
Section 382 of the Internal Revenue Code of 1986, the Company's ability to
utilize the net operating loss and tax credit carryovers would be restricted to
a prescribed annual amount (currently 5.75% of the market value of the Company
at the time of the ownership change). The Company has knowledge of equity
holdings and stock options which must be counted as changes in the ownership of
the Company aggregating about 22% as of the three years ended June 30, 1996.
 
8.  PREFERRED STOCK
 
     Preferred stock is noncumulative and convertible, at the option of the
holder, into one share of common stock. This conversion price is subject to
adjustment in the event of certain dilutive events. Each share of preferred
stock has voting rights equal to the number of common shares into which each
preferred share is then convertible. Preferred stock dividends, subject to the
approval of the board, are payable semi-annually at the rate of $.06 per share.
As of June 30, 1996 no preferred stock dividends have been declared.

9.  STOCK OPTIONS AND WARRANTS
 
  Incentive Stock Option Plans
 
     On July 2, 1993, the Board of Directors and Stockholders adopted a new
stock option plan (the Plan), which provides for qualified and non-qualified
stock options. Options are granted to key employees and directors to purchase
shares of the Company's common stock at not less than 100% of the fair market
value of the Company's common stock (to qualify as incentive stock options) as
determined by the Board of Directors at the time of the granting of such
options. At June 30, 1996, 439,000 shares were reserved for this plan.
 
     Options shall expire on such date as the Board of Directors shall
determine, but, in the case of Incentive Stock Options, in no event after the
expiration of ten years from the day on which the options are granted and shall
be subject to earlier or later termination as provided in the plan.

                          AGREEMENT AND PLAN OF MERGER
 
     Agreement entered into as of November   , 1996 by and among Thermo Optek
Corporation, a Delaware corporation (the "Buyer"), LSI Acquisition Corp., a
Delaware corporation and a wholly-owned subsidiary of the Buyer (the "Transitory
Subsidiary"), and Laser Science, Inc., a Delaware corporation (the "Company").
The Buyer, the Transitory Subsidiary and the Company are referred to
collectively herein as the "Parties."
 
     This Agreement contemplates a merger of the Transitory Subsidiary into the
Company. In such merger, the stockholders of the Company will receive capital
stock of the Buyer in exchange for their capital stock of the Company. The
parties intend that the merger will qualify as a "reorganization" under Section
368 of the Internal Revenue Code of 1986, as amended and in effect (the "Code").
 
     NOW, THEREFORE, in consideration of the representations, warranties and
covenants herein contained, the Parties agree as follows:
 
                                   ARTICLE I
                                   THE MERGER
 
     1.1  The Merger.  At the Effective Time (as defined in Section 1.3 below),
in accordance with this Agreement and the Delaware General Corporation Law (the
"Delaware Law"), the Transitory Subsidiary shall be merged with and into the
Company (the "Merger"), the separate existence of the Transitory Subsidiary
shall cease and the Company shall continue as the surviving corporation. The
Company is hereinafter sometimes referred to as the "Surviving Corporation."
 
     1.2  Effect of the Merger.  At the Effective Time, the Surviving
Corporation shall continue its corporate existence under the laws of the State
of Delaware and the Merger shall have the effects set forth in Section 259 of
the Delaware Law.
 
     1.3  Consummation of the Merger.  At the Closing (as defined in Section
1.6), the Parties will cause the Merger to be consummated by delivering to the
Secretary of State of the State of Delaware a certificate of merger or a
certificate of ownership and merger, together with officer's certificates, or a
certificate of ownership, each in such form or forms as may be required by, and
executed and acknowledged in accordance with, the relevant provisions of the
Delaware Law (such documents being referred to collectively as the "Merger
Documents"), and shall make all other filings and recordings required by the
Delaware Law in connection with the Merger. The Merger shall become effective at
the time of filing of the appropriate Merger Documents with the Secretary of
State of the State of Delaware, or at such later time, which shall be as soon as
reasonably practicable thereafter, specified as the effective time in the Merger
Documents (the "Effective Time").
 
     1.4  Certificate of Incorporation; Bylaws; Directors and Officers.  The
Certificate of Incorporation and By-laws of the Surviving Corporation shall be
the Certificate of Incorporation and By-laws of the Company as in effect
immediately prior to the Effective Time until thereafter amended as provided
under the Delaware Law. The directors of the Transitory Subsidiary immediately
prior to the Effective Date will be the initial directors of the Surviving
Corporation, and the officers of the Company immediately prior to the Effective
Date will be the initial officers of the Surviving Corporation, in each case
until their successors are elected and qualified.
 
     1.5  Conversion of Company Shares and Rollover of Options.
 
     (a) At the Effective Time, by virtue of the Merger and without any action
on the part of the Transitory Subsidiary, the Company, the Surviving Corporation
or the holder of any of the following securities:
 
          (i) Subject to Section 1.5(c) and (d), each share of the Company's
     common stock, $.07 par value per share (the "Company Common Stock"), issued
     and outstanding immediately prior to the Effective Time (the "Outstanding
     Common Stock") (other than shares to be canceled pursuant to subparagraph
 
                                       A-1
<PAGE>   100
 
     (iii) below), shall be canceled and extinguished and be converted into and
     become the right to receive a fraction of a share of the common stock, $.01
     par value, of the Buyer (the "Buyer Common Stock") determined in the manner
     set forth below. The fraction of a share of Buyer Common Stock into which a
     share of Company Common Stock is to be converted pursuant to the preceding
     sentence is referred to herein as the "Common Stock Exchange Ratio". The
     assumed value of each share of Buyer Common Stock to be issued in the
     Merger will be determined based on the average closing price for such stock
     on the American Stock Exchange during the 20 trading days prior to the date
     on which the Effective Time occurs (the "Average Price"). The total number
     of shares of Buyer Common Stock to be issued in the Merger will be equal to
     the quotient derived by dividing $3,400,000 by the Average Price.
 
          (ii) Each share of the Transitory Subsidiary's capital stock issued
     and outstanding immediately prior to the Effective Time shall be converted
     into and become one validly issued, fully paid and nonassessable share of
     the same class of capital stock of the Surviving Corporation.
 
     (b) The number of shares of Buyer Common Stock issuable in consideration
for the Company Shares shall be subject to adjustment after the Closing Date as
follows:
 
          (i) Within 30 days after the Closing Date (as defined in Section 1.6),
     [Joseph Caruso], as representative of the Company Stockholders (as defined
     in paragraph (ii) below) (the "Company Stockholder Representative"), shall
     prepare and deliver to the Buyer a balance sheet reflecting the net assets
     of the Company as of the Closing Date (the "Draft Closing Balance Sheet").
     The Draft Closing Balance Sheet shall be prepared in accordance with GAAP
     (as defined in Section 2.6 below). For purposes of this Agreement, "net
     assets" shall mean total assets of the Company minus total liabilities of
     the Company.
 
          (ii) Within 30 days after receiving the Draft Closing Balance Sheet,
     the Buyer shall deliver to the Company Stockholder Representative a
     detailed statement describing its objections (if any) thereto. Failure of
     the Buyer so to object to the Draft Closing Balance Sheet shall constitute
     acceptance thereof, whereupon the Draft Closing Balance Sheet shall be
     deemed to be the "Closing Balance Sheet". The Buyer and the Company
     Stockholder Representative shall use their best efforts to resolve any such
     objections, but if they do not reach a final resolution within 30 days
     after the Buyer has received the statement of objections, the Buyer and the
     Company Stockholder Representative shall select an internationally
     recognized accounting firm mutually acceptable to them (the "Neutral
     Auditors") to resolve any remaining objections. If the Buyer and the
     Company Stockholder Representative are unable to agree on the choice of
     Neutral Auditors, they shall select as Neutral Auditors a "big six"
     accounting firm other than Arthur Andersen LLP by lot. The Neutral Auditors
     shall determine whether the objections raised by the Buyer are valid. The
     Draft Closing Balance Sheet shall be adjusted in accordance with the
     Neutral Auditor's determination and, as so adjusted, shall be the Closing
     Balance Sheet. Such determination by the Neutral Auditors shall be
     conclusive and binding upon the Buyer and the stockholders of the Company
     as of the Effective Time (the "Company Stockholders"). The Buyer, on one
     hand, and the Company Stockholders, on the other, shall share equally the
     fees and expenses of the Neutral Auditors. The Company Stockholders'
     portion of such fees and expenses shall be deducted from the Indemnity
     Escrow Shares (as defined in Section 1.5(c)), as provided in the Escrow
     Agreement (as defined in Section 1.7).
 
          (iii) During the period of any dispute referred to above, the Buyer,
     the Company and the Company Stockholder Representative, and their
     respective accountants, shall cooperate fully toward final resolution of
     the Closing Balance Sheet. The Company Stockholder Representative shall
     have access (during normal business hours) to all books and records and
     other information of the Company reasonably necessary for the preparation
     of the Draft Closing Balance Sheet.
 
          (iv) If the net assets as shown on the Closing Balance Sheet are less
     than $909,933 [the Company's net assets as shown on its June 1996 balance
     sheet], then a number of Escrow Shares (as defined in Section 1.5(c))
     having a fair market value (as defined in the Escrow Agreement) equal to
     such shortfall shall be deducted from the Escrow Shares and returned by the
     Escrow Agent to the Buyer as provided in
 
                                       A-2

     the Escrow Agreement, and such shares shall not be issued in consideration
     for the Company Shares in the Merger.
 
          (v) The adoption of this Agreement and the approval of the Merger by
     the stockholders of the Company shall constitute approval of the
     appointment of the Company Stockholder Representative and ratification of
     all actions taken by the Company Stockholder Representative pursuant to
     this Section 1.5(b).
 
     (c) The shares of Buyer Common Stock actually issued pursuant to Section
1.5(a)(i) in consideration for the Company Shares are referred to as the "Merger
Consideration". The number of shares of Buyer Common Stock issued as Merger
Consideration (the "Buyer Shares") shall be subject to equitable adjustment in
the event of any stock split, stock dividend, reverse stock split or similar
event affecting the Buyer Common Stock between the date of this Agreement and
the Effective Time. Stockholders of record of the Company at the Effective Time
("Company Stockholders") shall be entitled to collectively receive at Closing
(as defined in Section 1.6 below) 80% of the Merger Consideration (the "Closing
Shares"). The shares of Buyer Common Stock representing the remaining 20% of the
Merger Consideration (the "Escrow Shares") shall be deposited in escrow pursuant
to Section 1.12 and shall be held and disposed of in accordance with the terms
of the Escrow Agreement (as defined in Section 1.7). The Escrow Shares shall be
held in escrow for purposes of securing the obligations of the Company
Stockholders under Article VI.
 
     (d) (i) Company Shares held by a holder who, subject to and in accordance
with Section 262 et seq. of the Delaware Law, has demanded and perfected his
right to an appraisal of his Company Shares and has not effectively withdrawn or
lost his right to such appraisal ("Dissenting Shares"), shall not be converted
into a right to receive the Merger Consideration, unless such holder, with the
consent of the Company, withdraws or otherwise loses his right to appraisal for
his Company Shares. If after the Effective Time such holder so withdraws or
loses his right to appraisal for his Company Shares, such Company Shares shall
be treated as if they had been converted as of the Effective Time into the right
to receive the Merger Consideration payable in respect of such Company Shares
pursuant to Section 1.5.
 
     (ii) The Company shall give the Buyer and the Transitory Subsidiary prompt
notice of any demands for purchase, or notices of intent to demand purchase,

each such Certificate shall be deemed for all purposes to evidence only the
right to receive the Merger Consideration and the holder of any such Certificate
shall cease to have any rights as a shareholder of the Company. Holders of
Certificates shall not be entitled to receive Merger Consideration to which they
would otherwise be entitled until such Certificates are properly surrendered.
 
     (b) In the event any Certificate shall have been lost, stolen or destroyed,
upon the making of an affidavit of that fact by the person claiming such
Certificate to be lost, stolen or destroyed, the Buyer shall issue in exchange
for such lost, stolen or destroyed Certificate the Merger Consideration issuable
in exchange therefor as provided Section 1.5. The Buyer may, in its discretion
and as a condition precedent to the issuance thereof, require the owner of such
lost, stolen or destroyed Certificate to give the Buyer an affidavit attesting
to the loss, theft or destruction of such certificate and agreeing to indemnify
the Buyer with respect to the Certificate alleged to have been lost, stolen or
destroyed.
 
     1.10  Dividends.  No dividends or other distributions that are payable to
the holders of record of Buyer Common Stock as of a date on or after the Closing

Buyer Shares that would otherwise be issued to such former Company Stockholders.
In lieu of any fractional Buyer Shares that would otherwise be issued, each
former Company Stockholder that would have been entitled to receive a fractional
Buyer Share shall, upon proper surrender of such person's Certificates, receive
a cash payment equal to the closing price per share of the Buyer Common Stock on
the American Stock Exchange on the business day immediately preceding the
Closing Date, multiplied by the fraction of a share that such Company
Stockholder would otherwise be entitled to receive.

     2.32  Registration Statement; Information Statement/Prospectus.
 
     (a) None of the information supplied or to be supplied by the Company for
inclusion or incorporation by reference in (i) the Registration Statement on
Form S-4 to be filed with the Securities and Exchange Commission (the
"Commission") by the Buyer in connection with the submission of this Agreement
to the Company's Stockholders and the issuance of Buyer Shares in the Merger
(together with any amendments or supplements thereto, the "Registration
Statement") or (ii) the information statement relating to the written consents
to be executed by the Company Stockholders in connection with the Merger (the
"Information Statement" and, together with the prospectus contained in the
Registration Statement, the "Information Statement/Prospectus") will, at the
respective times filed with the Commission and, in addition (A) in the case of
the Information Statement/Prospectus, at the date it or any amendments or
supplements thereto are mailed to stockholders, and at the Effective Time, and
(B) in the case of the Registration Statement, when it becomes effective under
the Securities Act and the Effective Time, contain any untrue statement of a
material fact or omit to state any material fact required to be stated therein
or necessary in order to make the statements therein, in light of the
circumstances under which they are made, not misleading. The information
contained in the Registration Statement and the Information Statement, insofar
as it pertains to the Company, its officers, directors, shareholders or
affiliates, will comply in all material respects with the applicable provisions
of the Securities Act and the Exchange Act and the rules and regulations
thereunder. If at any time prior to the Effective Time any event relating to the
Company or any of its respective Affiliates, officers or directors should be
discovered by the Company which should be set forth in an amendment to the
Registration Statement or a supplement to the Information Statement/Prospectus,
the Company shall promptly inform the Buyer. Notwithstanding the foregoing, the
Company makes no representation or warranty with respect to any information
supplied by the Buyer or the Transitory Subsidiary which is contained in any of
the foregoing documents.

"offer to sell", "offer for sale" or "sale" of Buyer Shares within the meaning

     2.33  Continuity of Interest.  To the Company's knowledge, there is no plan

reduce the Company Stockholders' ownership of Buyer Common Stock to a number of
shares having a value, as of the Effective Time, of less than fifty (50%)
percent of the value of all of the Company Shares as of the Effective Time. For
purposes of this representation, (i) Company Shares surrendered by dissenters or
exchanged for cash or in lieu of fractional shares of Buyer Common Stock will be
treated as outstanding Company Shares at the Effective Time and (ii) shares of
Buyer Common Stock held by the Company Stockholders and otherwise sold,
redeemed, or disposed of prior or subsequent to the Merger shall be considered
in determining such value. The Company has caused each person who is an
Affiliate to deliver to Buyer and each Affiliate has, concurrently with the
signing of this Agreement, signed an affiliate agreement in the form attached
hereto as Exhibit C (an "Affiliate Agreement").

     therefrom. The Indemnified Party shall not settle or compromise any claim
     by a third party for which it is entitled to indemnification hereunder
     without the prior written consent, which shall not be unreasonably withheld
     or delayed, of the Indemnifying Party; provided, however, that if suit
     shall have been instituted against an Indemnified Party and the
     Indemnifying Party shall not have taken control of such suit after
     notification thereof as provided in Section 6.4 of this Agreement (if
     permitted by such Section), the Indemnified Party shall have the right to
     settle or compromise such claim as provided in Section 6.4. The Company
     Stockholders' Representative shall have the power and authority to bind all
     the Company Stockholders for all purposes of this Article VI.
 
     6.4  Defense by the Indemnifying Party.  In connection with any claim which
may give rise to indemnity hereunder resulting from or arising out of any claim
or legal proceeding by a person other than the Indemnified Party, the
Indemnifying Party, at his or its sole cost and expense, may, upon written
notice to the Indemnified Party, assume the defense of any such claim or legal
proceeding if (i) the Indemnifying Party
 
                                      A-22
<PAGE>   121
 
acknowledges to the Indemnified Party in writing the obligation of the
Indemnifying Party to indemnify the Indemnified Party with respect to all
elements of such claim, (ii) the third party seeks monetary damages solely and
(iii) an adverse resolution of the third party's claim would not have a material
adverse effect on the goodwill or reputation of the Buyer or the Company or on
the future conduct of the business of the Buyer or the Company. If the
Indemnifying Party assumes the defense of any such claim or legal proceeding,
the Indemnifying Party shall select counsel reasonably acceptable to the
Indemnified Party to conduct the defense of such claims or legal proceedings and
at the sole cost and expense of the Indemnifying Party shall take all steps
necessary in the defense or settlement thereof. The Indemnifying Party shall not
consent to a settlement of, or the entry of any judgment arising from, any such
claim or legal proceeding, without the prior written consent of the Indemnified
Party (which consent shall not be unreasonably withheld or delayed). The
Indemnified Party shall be entitled to participate in (but not control) the
defense of any such action, with its own counsel and at its own expense (except
that the Indemnifying Party will be responsible for the fees and expenses of the
separate co-counsel to the extent the Indemnified Party reasonably concludes
that the counsel the Indemnifying Party has selected has a conflict of
interest). If the Indemnifying Party does not assume the defense of any such
claim or litigation resulting therefrom as provided in this Section 6.4 within
30 days after the date that the Indemnified Party has given notice of the claim
to the Indemnifying Party: (a) the Indemnified Party may defend against such
claim or litigation in such manner as he or it may deem appropriate, including,
but not limited to, settling such claim or litigation on such terms as the
Indemnified Party may deem appropriate; and (b) the Indemnifying Party shall be
entitled to participate in (but not control) the defense of such action, with
his or its counsel and at his or its own expense.
 
     6.5  Survival.  Except as otherwise provided in this Section 6.5, the
representations and warranties of the Company set forth in this Agreement shall
survive the Closing and the consummation of the transactions contemplated hereby
and continue until 18 months after the Closing Date. Notwithstanding the
foregoing, the representations and warranties contained in Sections 2.1 through
2.5 shall survive indefinitely. If a notice of claim is given by an indemnified
party before expiration of such periods, then (notwithstanding the expiration of
such time period) the representation or warranty applicable to such claim shall
survive until, but only for purposes of, the resolution of such claim.
 
     6.6  Limitation on Indemnification Obligation.  Except as otherwise set
forth in this Section 6.6, the Company Stockholders will only have liability for
indemnification pursuant to Section 6.1(a), and the Buyer will only have
liability for indemnification pursuant to Section 6.2(a), if and to the extent
that the total of all Losses incurred by the indemnified parties thereunder
exceed $35,000, and then only for the amount by which the total of all such
Losses exceeds $35,000 and is less than $680,000. The Company Stockholders will
only have liability for indemnification pursuant to Section 6.1(a) for breaches
of the representations and warranties set forth in (a) Section 2.21 if and to
the extent that the total of all Losses incurred by the indemnified parties
under Section 6.1(a) exceed $35,000, and then only for the amount by which the
total of all such Losses does not exceed $1,700,000, and (b) Sections 2.1
through 2.5, inclusive, if and to the extent that the total of all Losses
incurred by the indemnified parties under Section 6.1(a) exceed $35,000, and
then only for the amount by which the total of all such Losses does not exceed
the Purchase Price.
 
     Indemnification of the Buyer, the Surviving Corporation and the Transitory
Subsidiary for any breach of Section 6.1(c) shall be the sole responsibility of
the Company Stockholder causing such breach, and the indemnified parities shall
not look to any other Company Stockholder for such indemnification.

     Section 2.  Consent of Company Stockholders.  By virtue of the Company
Stockholders' approval of the Merger Agreement, the Company Stockholders have,
without any further act of any Company Stockholder, consented to: (a) the
establishment of the escrow account to secure the Company's indemnification
obligations under Section 4 of this Agreement and the obligations, if any, of
the Company under Section 1.5(b) of the Merger Agreement, in the manner set
forth herein, (b) the appointment of the Company Stockholder Representative as
their representative for purposes of this Agreement and as attorney-in-fact and
as agent for and on behalf of each Company Stockholder, (c) the taking by the
Company Stockholder Representative of any and all actions and the making of any
decisions required or permitted to be taken or made by him under this Agreement
and (d) all of the other terms, conditions and limitations of this Agreement.
 
     Section 3.  Deposit of Escrow Property.
 
     (a) The Buyer shall cause the Exchange Agent to withhold 20% of the Buyer
Shares issuable to each former Company Stockholder in exchange for Company
Shares, representing such former Company Stockholder's portion of the Indemnity
Escrow Shares. From time to time after the Effective Time and as certificates
representing Buyer Shares are issued to former Company Stockholders in exchange
for Company Shares duly submitted for exchange, the Buyer shall cause the
Exchange Agent to deposit certificates with the Escrow Agent representing the
Buyer Shares withheld as provided in the preceding sentence. Such certificates
will be issued in the name of the Escrow Agent or its nominee and held pursuant
to the terms hereof. The Buyer Shares so withheld are referred to herein as the
"Escrow Shares."
 
     (b) In case any distribution (except a cash dividend paid out of earned
surplus) or stock dividend shall be made on or in respect of the Escrow Shares,
or any property shall be distributed upon or with respect to the Escrow Shares
pursuant to the recapitalization, liquidation or reclassification of the capital
structure of the
 
                                      A-28
<PAGE>   127
 
Buyer or pursuant to the merger, consolidation or reorganization of the Buyer,
the money, stock or property so distributed or paid shall be delivered to and
held by Escrow Agent hereunder. Such money, stock and property, together with
the Escrow Shares, are sometimes referred to hereinafter as the "Escrow
Property." Company Stockholders shall be entitled to receive, in proportion to
their respective number of Escrow Shares, all cash dividends paid in respect of
the Escrow Shares out of the earned surplus of the Buyer.
 
     While the Escrow Shares are held by Escrow Agent, Company Stockholders
shall be entitled to direct Escrow Agent as to how to vote the Escrow Shares, in
proportion to their respective number of Escrow Shares, with respect to matters
placed before the shareholders of the Buyer, and Escrow Agent shall vote
accordingly.
 
     Section 4.  Holding and Distribution of Escrow Property.
 
     (a) If the Closing occurs, the Buyer, the Surviving Corporation and the
Transitory Subsidiary shall be indemnified by the Company Stockholders from and
against any and all claims, damages, losses, diminution of value, liabilities,
costs and expenses (including, without limitation, settlement costs and any
legal, accounting, consulting or other fees or expenses for investigating or
defending any actions or threatened actions) whether or not involving a
third-party claim (collectively, the "Damages") arising out of, constituting or
related to each and all of the following:
 
          (i) any misrepresentation or breach of any representation or warranty
     made by the Company in Article II of the Merger Agreement or in any
     statement, certificate or Schedule furnished by the Company pursuant to the
     Merger Agreement;
 
          (ii) any breach of any covenant, agreement or obligation of the
     Company contained in the Merger Agreement or any other agreement,
     instrument or document contemplated by the Merger Agreement; and
 
          (iii) any failure of any Company Stockholder to have good, valid and
     marketable title to the issued and outstanding Company Shares held by such
     Company Stockholder, free and clear of all liens, claims, pledges, options,
     adverse claims or charges of any nature whatsoever.
 
     The Buyer shall give the Company Stockholder Representative notice of any
claim, action or proceeding by a third party which is reasonably likely to
result in a claim for indemnification under this Section 4. The Company
Stockholder Representative shall have the right to defend, contest, protest and
otherwise control the resolution of any such claim, action or proceeding (unless
such claim, action or proceeding relates to equitable relief sought against the
Company or to a matter which, if adversely determined, would have an impact on
(A) the Surviving Corporation's or the Buyer's liability in another proceeding,
(B) relations of the Buyer or the Surviving Corporation with any Governmental
Entity or (C) the future conduct by the Surviving Corporation or the Buyer of
its business or on its Tax or accounting positions, in which case the next
paragraph shall apply), at his expense, but shall keep the Buyer apprised of
material developments. The Buyer shall have the right to participate in any such
legal proceeding, subject to the Company Stockholder Representative's right of
control thereof, at the expense of the Buyer by counsel of the Buyer's choice.
The Company Stockholder Representative, acting in good faith, shall have the
right in its sole discretion to settle any such claim.
 
     If the claim, action or proceeding is of a type referred to in the
parenthetical contained in the second sentence of the preceding paragraph, then
(i) the Buyer shall have the right, at the Company Stockholder Representative's
expense, to defend, contest, protest and otherwise control the resolution
thereof, but shall keep the Company Stockholder Representative apprised of
material developments and (ii) the Company Stockholder Representative shall have
the right to participate in any such legal proceeding, subject to the Buyer's
right of control thereof, at the Company Stockholder Representative's expense
and with counsel selected by the Company Stockholder Representative. The Buyer,
acting in good faith, shall have the right in its sole discretion to settle any
such claim.
 
     (b) The Company Stockholders hereby designate and appoint the Company
Stockholder Representative as their representative and attorney-in-fact through
whom all actions relating to this Agreement after the Closing Date, including
those acts as are required, authorized or contemplated by this Agreement with
respect to the settlement of a claim or the defense thereof, shall be made or
directed, and hereby acknowledge that the
 
                                      A-29
<PAGE>   128
 
Company Stockholder Representative shall be the only person authorized to take
any action so required, authorized or contemplated by this Agreement on behalf
of the Company Stockholders. The Company Stockholders further acknowledge that
the foregoing appointment and designation shall be deemed to be coupled with an
interest and shall survive the disability, death or incompetency of any Company
Stockholder. The other parties hereto are and will be entitled to rely on any
action so taken or any notice given by the Company Stockholder Representative
and entitled and authorized to give notices only to the Company Stockholder
Representative for any notice contemplated by this Agreement to be given any
such person. The Company Stockholder Representative shall serve without
compensation but shall be reimbursed for his reasonable out-of-pocket expenses
from the Escrow Property. The Company Stockholder Representative shall have the
right to sell Escrow Property in order to obtain funds to pay such expenses. The
Company Stockholder Representative shall furnish reports as to the status of the
escrow to the Company Stockholders as and when Escrow Shares are released from
the escrow or claims are paid. The Buyer, the Transitory Subsidiary or the
Surviving Corporation shall not have any liability or responsibility to the
Company Stockholder Representative.
 
     The Company Stockholder Representative shall receive and deliver notices on
behalf of the Company Stockholders and take all such action as in the Company
Stockholder Representative's discretion may be necessary, appropriate, permitted
or advisable to be taken under the terms of this agreement in order to consent
to, pay, contest, arbitrate, litigate or settle any claim or alleged claim
asserted hereunder.
 
     The Company Stockholder Representative shall not be personally liable to
the other Company Stockholders for any action taken, suffered or omitted by him
in good faith and reasonably believed by him to be authorized or within the
discretion of the rights or powers conferred upon him by this Agreement.
 
     In acting as representative of the Company Stockholders, the Company
Stockholder Representative may rely upon, and shall be protected in acting or
refraining from acting upon, an opinion of counsel, certificate of auditors or
other certificate, statement, instrument, opinion, report, notice, request,
consent, order, arbitrator's award, appraisal, bond or other paper or document
reasonably believed by him to be genuine and to have been signed or presented by
the proper party or parties. The Company Stockholder Representative may consult
with counsel and any advice of such counsel shall be full and complete
authorization and protection in respect to any action taken or suffered or
omitted by him in such capacity in good faith and in accordance with such
opinion of counsel. The Company Stockholder Representative may perform his
duties as Company Stockholder Representative either directly or by or through
his agents or attorneys and the Company Stockholder Representative shall not be
responsible to the other Company Stockholders for any misconduct or negligence
on the part of any agent or attorney appointed with reasonable care by him
hereunder.
 
     Upon receiving notice of the death or incapacity of the Company Stockholder
Representative, the Company Stockholders shall by majority vote (based on the
number of Closing Shares received by each Company Stockholder) appoint a
successor to fill the vacancy. The Company Stockholders may by such a majority
vote remove the Company Stockholder Representative with or without cause and
appoint a successor, provided that notice thereof is given by the new Company
Stockholder Representative to each of the other parties hereto. The Company
Stockholder Representative may resign if, and only if, he is simultaneously
replaced with a substitute Company Stockholder Representative reasonably
acceptable to the Buyer.
 
     Section 5.  Limitation of Liability.  The Company Stockholders will only
have liability for indemnification pursuant to Section 4 to the extent and for
the periods set forth in Article VI of the Merger Agreement. If a notice is
given before expiration of such periods, then (notwithstanding the expiration of
such time period) the representation or warranty applicable to such claim shall
survive until, but only for purposes of, the resolution of such claim.
Notwithstanding the foregoing, this Section 5 and the limitations of liability
set forth in Article VI of the Merger Agreement shall not apply in the event the
Company has actual knowledge of a breach of a representation or warranty as of
the Closing Date.
 
     Section 6.  Escrow Account.  It is intended that the assets held in escrow
as above provided shall facilitate the Buyer's and the Surviving Corporation's
ability to recover amounts to which they are entitled as a result of
misrepresentations, breaches of warranties and breaches of covenants contained
in the Merger
 
                                      A-30
<PAGE>   129
 
Agreement or this Agreement and to satisfy other claims of the Buyer and the
Surviving Corporation arising as under the Merger Agreement or this Agreement,
including satisfaction of the Company's obligations under Section 1.5(b) of the
Merger Agreement. Accordingly, and to the extent necessary to provide such
protection to the Buyer and the Surviving Corporation, property held in escrow
hereunder shall be available to satisfy claims of the Buyer and the Surviving
Corporation under this Agreement to the extent provided herein. In the event the
Escrow Property is insufficient to pay all amounts owed to the Buyer, the
Transitory Subsidiary and the Surviving Corporation, the Company Stockholder
shall remain liable to such parties for any such amounts.
 
     Section 7.  Registration of Claims.  In the event that the Buyer or the
Surviving Corporation asserts any claim for indemnification against the Escrow
Shares, or any claim under Section 1.5(b) of the Merger Agreement, it shall
deliver to Escrow Agent and the Company Stockholder Representative a written
notice thereof (the "Notice of Claim") setting forth (a) a demand for payment of
a specified amount from the Escrow Shares or, if such amount can not be
specified, the basis upon which the amount would be determined and (b) a
description of the asserted claim and the basis thereof, and the Buyer shall
deliver to the Company Stockholder Representative thereafter such other
information as may be reasonably requested by the Company Stockholder
Representative to evaluate the asserted claim. It is understood and agreed among
the parties hereto that the Buyer's and the Surviving Corporation's right to
assert claims for indemnification under this Agreement is limited to those
matters set forth in this Agreement, although the Escrow Agent shall have no
obligation to determine or verify whether such condition has been met.
 
     Section 8.  Payment of Amounts from Escrow Property Upon Demand Without
Objection.  If the Buyer delivers to the Company Stockholder Representative and
Escrow Agent a Notice of Claim pursuant to Section 4 hereof and if no written
objection to such demand is received by Escrow Agent and the Buyer from the
Company Stockholder Representative within 30 days following the delivery of such
Notice of Claim to Escrow Agent and the Company Stockholder Representative, then
Escrow Agent shall pay the claim out of the Escrow Property by forthwith
endorsing and delivering to the Buyer the certificates representing the
Indemnity Escrow Shares. The Buyer shall be entitled to retain that number of
Escrow Shares which, when multiplied by the fair market value (as defined
below), shall equal the amount of the claim; provided, however, that Notices of
Claim must be delivered before the Escrow Termination Date. The Buyer shall
return one or more certificates for the excess Escrow Shares to Escrow Agent for
continued holding hereunder. To the extent the value (calculated on the basis of
the fair market value, regardless of actual market value at the time) of the
Indemnity Escrow Shares retained by the Buyer is less than the amount of the
claim, Escrow Agent shall also transfer to the Buyer other Escrow Property (but
not other Escrow Shares), if any, in addition to such Indemnity Escrow Shares.
 
     The fair market value shall be $      per share, representing the average
of the reported closing prices of the Buyer's Common Stock on the American Stock
Exchange during the 20 trading days ended on December 27, 1996, as adjusted
appropriately to reflect any stock, splits, stock dividends or similar
recapitalizations.
 
     Section 9.  Payment of Amounts from Escrow Property After Notice of
Objection.  If the Buyer delivers to the Company Stockholder Representative and
Escrow Agent a Notice of Claim pursuant to Section 4 hereof, and if the Company
Stockholder Representative shall give written objection thereto to Escrow Agent
and the Buyer prior to the expiration of the 30-day period specified in Section
8, Escrow Agent shall make no payment in respect of the demand set forth in such
Notice of Claim until it shall have received one of the following:
 
          (a) written instructions signed on behalf of both the Buyer and the
     Company Stockholder Representative; or
 
          (b) a final order of a court having jurisdiction over the asserted
     claim, after expiration of any applicable appeal period.
 
     Upon receipt of any such instructions or order, Escrow Agent shall pay such
amount from the Escrow Property to the Buyer as may be directed by such
instructions or order; provided, however that (i) the limitations set forth in
Section 8 hereof on the number of Escrow Shares retainable by the Buyer shall
also apply to claims paid under this Section 9, and (ii) all Escrow Shares
delivered to the Buyer shall be valued on
 
                                      A-31
<PAGE>   130
 
the basis of the fair market value, regardless of the actual market price of the
Buyer's Common Stock on the date such shares are delivered to the Buyer. If the
final order of a court having jurisdiction over the asserted claim, after
expiration of any applicable appeal period, upholds the Company Stockholder
Representative's objection to the Escrow Agent, the Buyer shall reimburse the
Escrow Agent for reasonable attorneys' fees and expenses paid from the Escrow
Property to pursue the objection. If the final order of such court, after any
applicable appeal period, upholds the Buyer's claim, no such reimbursement shall
be made.
 
     Section 10.  Payment of Escrow Property to Shareholders.
 
     (a) On the Escrow Termination Date, Escrow Agent shall deliver to the Buyer
and the Company Stockholder Representative a statement of the remaining balance,
if any, of the Escrow Property (calculated on the basis of the fair market
value, regardless of the actual market price of the Buyer's Common Stock at that
time), and the total amount of all claims registered pursuant to Section 7
hereof and not theretofore resolved and paid (the excess, if any, of such
remaining balance over the total amount of such claims shall be referred to as
the "Final Escrow Balance"). The Buyer and the Company Stockholder
Representative shall review the accuracy of the Final Escrow Balance and notify
Escrow Agent within 30 days of the receipt of the foregoing statement of any
asserted discrepancy. Upon the expiration of the 30-day period after receipt by
the Buyer and the Company Stockholder Representative of such statement, and if
Escrow Agent has not been notified of any discrepancy by the Buyer or the
Company Stockholder Representative within the 30-day period specified in the
preceding sentence, Escrow Agent shall deliver to each Company Stockholder
Escrow Property representing such Company Stockholder's share of the Final
Escrow Balance, free and clear of the escrow created by this Agreement. After
the last registered claim shall have been resolved pursuant to Section 8 and
Section 9 hereof, as the case may be, and paid, the remaining balance, if any,
of the Escrow Property shall be delivered by Escrow Agent to Company
Stockholders, free and clear of the escrow created by this Agreement; provided,
however, that upon the disposition of any such claim prior to the disposition of
all such claims Escrow Agent shall deliver to Company Stockholders the Escrow
Property in excess of the amount of the remaining aggregate claims as determined
above. All payments by Escrow Agent to Company Stockholders pursuant to this
Agreement shall be made in proportion to the Company Stockholders' respective
interests in the Escrow Shares.
 
     Section 11.  Responsibility of Escrow Agent.  Escrow Agent may act upon any
instrument or other writing believed by it in good faith to be genuine and to
have been signed or presented by the proper person and shall not be liable to
any party hereto in connection with the performance of its duties hereunder,
except for its own negligence or willful misconduct. Escrow Agent's duties shall
be determined only with reference to this Escrow Agreement and applicable laws
and Escrow Agent is not charged with knowledge of, or any duties or
responsibilities in connection with, any other document or agreement. If in
doubt as to its duties and responsibilities hereunder, Escrow Agent may consult
with counsel of its choice and shall be protected in any action taken or omitted
in connection with the advice or opinion of such counsel.
 
     If any party to this Agreement disagrees on anything connected with this
escrow (a) Escrow Agent will not have to settle the matter, (b) Escrow Agent may
wait for a settlement by appropriate legal proceedings or other means it may
require, and in such event it will not be liable for interest or damage, (c) if
Escrow Agent intervenes in or is made a party to any legal proceedings, it will
be entitled to such reasonable compensation for services, costs and attorney's
fees as the court may award and (d) Escrow Agent is entitled to hold documents
and assets deposited in this escrow pending settlement of the disagreement by
any of the above means.
 
     Escrow Agent is to act as a depositary agent only and is hereby relieved of
any liability in connection with any representations made by the other parties
hereto or any of their agents. Escrow Agent shall not be responsible for and
shall not be under a duty to examine any other agreement.
 
     Section 12.  Indemnification and Fees of Escrow Agent.  In consideration of
its acceptance of the appointment as Escrow Agent, the Escrow Agent and shall be
indemnified and held harmless as to any liability incurred by it to any other
person, firm or corporation by reason of its having accepted the same or in
carrying out any of the terms hereof, and shall be reimbursed for all its
out-of-pocket expenses, including, among other things, reasonable counsel fees
and court costs, incurred by reason of its position hereunder or
 
                                      A-32
<PAGE>   131
 
actions taken pursuant hereto, except in the event of the negligence or willful
misconduct of Escrow Agent. The fees and charges set forth below for the
services of Escrow Agent will be considered compensation for Escrow Agent's
ordinary services as contemplated by this Agreement. In the event the conditions
of the escrow are not promptly fulfilled or Escrow Agent renders any service not
provided for in this Agreement or there is any assignment of any interest in the
subject matter of this escrow or modification of any interest or if any
controversy arises in connection with it, Escrow Agent will be reasonably
compensated for such extraordinary services, and will be reimbursed for all
reasonable costs, attorney's fees and expenses occasioned thereby. Except as
provided in Section 9, the fees and expenses of Escrow Agent and any other
amounts due the Escrow Agent under this Section 12 shall be reimbursed 50% by
Buyer and 50% out of the Escrow Property.
 
     Section 13.  Resignation of Escrow Agent.  Escrow Agent may resign and be
discharged from its duties hereunder at any time by giving not less than 60 days
prior written notice of such resignation to the Buyer and the Company
Stockholder Representative, which notice shall specify the date when such
resignation shall take effect. Upon such notice, the Buyer and the Company
Stockholder Representative shall appoint a successor escrow agent. If the Buyer
and the Company Stockholder Representative are unable to agree upon a successor
escrow agent within 30 days after receipt of such notice, Escrow Agent may apply
to a court of competent jurisdiction for such appointment. Escrow Agent shall
continue to serve until its successor delivers to the Buyer and the Company
Stockholder Representative a duly executed instrument of acceptance of the terms
and conditions of this Agreement and receives the Escrow Property.
 
     Section 14.  Investments.  Escrow Agent shall invest the cash portion of
the Escrow Property, if any, in money market accounts mutually acceptable to the
Buyer, the Company Stockholder Representative and the Escrow Agent. Income from
any such investment shall be held by Escrow Agent, shall be reinvested in
accordance with this Section 14 and shall be considered part of the Escrow
Property.
 
     Section 15.  Security Interest.  To secure the obligations that may be owed
it hereunder, the Buyer shall have a security interest in the Escrow Property,
and for purposes of protection of an enforceable security interest, possession
of the Escrow Property by the Escrow Agent shall be deemed possession by the
Buyer.

voted in favor of the merger or consolidation nor consented thereto in writing
pursuant to sec.228 of this title shall be entitled to an appraisal by the Court
of Chancery of the fair value of his shares of stock under the circumstances
described in subsections (b) and (c) of this section. As used in this section,
the word "stockholder" means a holder of record of stock in a stock corporation
and also a member of record of a nonstock corporation; the words "stock" and
"share" mean and include what is ordinarily meant by those words and also
membership or membership interest of a member of a nonstock corporation; and the
words "depository receipt" mean a receipt or other instrument issued by a
depository representing an instrument issued by a depository representing an
interest in one or more shares, or fractions thereof, solely of stock of a
corporation, which stock is deposited with the depository.
 
     (b) Appraisal rights shall be available for the shares of any class or
series of stock of a constituent corporation in a merger or consolidation to be
effected pursuant to sec.251, 252, 254, 257, 258, 263 or 264 of this title:
 
     (1) Provided, however, that no appraisal rights under this section shall be
available for the shares of any class or series of stock, which stock, or
depository receipts in respect thereof, at the record date fixed to determine
the stockholders entitled to receive notice of and to vote at the meeting of
stockholders to act upon the agreement of merger or consolidation, were either
(i) listed on a national securities exchange or designated as a national market
system security on an interdealer quotation system by the National Association
of Securities Dealers, Inc. or (ii) held of record by more than 2,000 holders;
and further provided that no appraisal rights shall be available for any shares
of stock of the constituent corporation surviving a merger if the merger did not
require for its approval the vote of the stockholders of the surviving
corporation as provided in subsections (f) or (g) of sec.251 of this title.
 
     (2) Notwithstanding paragraph (1) of this subsection, appraisal rights
under this section shall be available for the shares of any class or series of
stock of a constituent corporation if the holders thereof are required by the
terms of an agreement of merger or consolidation pursuant to sec.251, 252, 254,
257, 258, 263 and 264 of this title to accept for such stock anything except:
 
          a. Shares of stock of the corporation surviving or resulting from such
     merger or consolidation, or depository receipts in respect thereof;
 
          b. Shares of stock of any other corporation, or depository receipts in
     respect thereof, which shares of stock or depository receipts at the
     effective date of the merger or consolidation will be either listed on a
     national securities exchange or designated as a national market system
     security on an interdealer quotation system by the National Association of
     Securities Dealers, Inc. or held of record by more than 2,000 holders;
 
          c. Cash in lieu of fractional shares or fractional depository receipts
     described in the foregoing subparagraphs a. and b. of this paragraph; or
 
          d. Any combination of the shares of stock, depository receipts and
     cash in lieu of fractional shares or fractional depository receipts
     described in the foregoing subparagraphs a., b. and c. of this paragraph.
 
     (3) In the event all of the stock of a subsidiary Delaware corporation
party to a merger effected under sec.253 of this title is not owned by the
parent corporation immediately prior to the merger, appraisal rights shall be
available for the shares of the subsidiary Delaware corporation.
 
     (c) Any corporation may provide in its certificate of incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its certificate of
incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all or substantially all of the assets of
the corporation. If the certificate of incorporation contains such a
 
                                       B-1
<PAGE>   135
 
provision, the procedures of this section, including those set forth in
subsections (d) and (e) of this section, shall apply as nearly as is
practicable.
 
     (d) Appraisal rights shall be perfected as follows:
 
     (1) If a proposed merger or consolidation for which appraisal rights are
provided under this section is to be submitted for approval at a meeting of
stockholders, the corporation, not less than 20 days prior to the meeting, shall
notify each of its stockholders who was such on the record date for such meeting
with respect to shares for which appraisal rights are available pursuant to
subsections (b) or (c) hereof that appraisal rights are available for any or all
of the shares of the constituent corporations, and shall include in such notice
a copy of this section. Each stockholder electing to demand the appraisal of his
shares shall deliver to the corporation, before the taking of the vote on the
merger or consolidation, a written demand for appraisal of his shares. Such
demand will be sufficient if it reasonably informs the corporation of the
identity of the stockholder and that the stockholder intends thereby to demand
the appraisal of his shares. A proxy or vote against the merger or consolidation
shall not constitute such a demand. A stockholder electing to take such action
must do so by a separate written demand as herein provided. Within 10 days after
the effective date of such merger or consolidation, the surviving or resulting
corporation shall notify each stockholder of each constituent corporation who
has complied with this subsection and has not voted in favor of or consented to
the merger or consolidation of the date that the merger or consolidation has
become effective; or
 
     (2) If the merger or consolidation was approved pursuant to sec.228 or 253
of this title, the surviving or resulting corporation, either before the
effective date of the merger or consolidation or within 10 days thereafter,
shall notify each of the stockholders entitled to appraisal rights of the
effective date of the merger or consolidation and that appraisal rights are
available for any or all of the shares of the constituent corporation, and shall
include in such notice a copy of this section. The notice shall be sent by
certified or registered mail, return receipt requested, addressed to the
stockholder at his address as it appears on the records of the corporation. Any
stockholder entitled to appraisal rights may, within 20 days after the date of
mailing of the notice, demand in writing from the surviving or resulting
corporation the appraisal of his shares. Such demand will be sufficient if it
reasonably informs the corporation of the identity of the stockholder and that
the stockholder intends thereby to demand the appraisal of his shares.
 
     (e) Within 120 days after the effective date of the merger or
consolidation, the surviving or resulting corporation or any stockholder who has
complied with subsections (a) and (d) hereof and who is otherwise entitled to
appraisal rights, may file a petition in the Court of Chancery demanding a
determination of the value of the stock of all such stockholders.
Notwithstanding the foregoing, at any time within 60 days after the effective
date of the merger or consolidation, any stockholder shall have the right to
withdraw his demand for appraisal and to accept the terms offered upon the
merger or consolidation. Within 120 days after the effective date of the merger
or consolidation, any stockholder who has complied with the requirements of
subsection (a) and (d) hereof, upon written request, shall be entitled to
receive from the corporation surviving the merger or resulting from the
consolidation a statement setting forth the aggregate number of shares not voted
in favor of the merger or consolidation and with respect to which demands for
appraisal have been received and the aggregate number of holders of such shares.
Such written statement shall be mailed to the stockholder within 10 days after
his written request for such a statement is received by the surviving or
resulting corporation or within 10 days after expiration of the period for
delivery of demands for appraisal under subsection (d) hereof, whichever is
later.
 
     (f) Upon the filing of any such petition by a stockholder, service of a
copy thereof shall be made upon the surviving or resulting corporation, which
shall within 20 days after such service file in the office of the Register in
Chancery in which the petition was filed a duly verified list containing the
names and addresses of all stockholders who have demanded payment for their
shares and with whom agreements as to the value of their shares have not been
reached by the surviving or resulting corporation. If the petition shall be
filed by the surviving or resulting corporation, the petition shall be
accompanied by such a duly verified list. The Register in Chancery, if so
ordered by the Court, shall give notice of the time and place fixed for the
hearing of such petition by registered or certified mail to the surviving or
resulting corporation and to the stockholders shown on the list at the address
therein stated. Such notice shall also be given by 1 or more publications at
least 1
 
                                       B-2
<PAGE>   136
 
week before the day of the hearing, in a newspaper of general circulation
published in the City of Wilmington, Delaware or such publication as the Court
deems advisable. The forms of the notices by mail and by publication shall be
approved by the Court, and the costs thereof shall be borne by the surviving or
resulting corporation.
 
     (g) At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled to
appraisal rights. The Court may require the stockholders who have demanded an
appraisal for their shares and who hold stock represented by certificates to
submit their certificates of stock to the Register in Chancery for notation
thereon of the pendency of the appraisal proceedings; and if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as to
such stockholder.
 
     (h) After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any element
of value arising from the accomplishment or expectation of the merger or
consolidation, together with a fair rate of interest, if any, to be paid upon
the amount determined to be the fair value. In determining such fair value, the
Court shall take into account all relevant factors. In determining the fair rate
of interest, the Court may consider all relevant factors, including the rate of
interest which the surviving or resulting corporation would have had to pay to
borrow money during the pendency of the proceeding. Upon application by the
surviving or resulting corporation or by any stockholder entitled to participate
in the appraisal proceeding, the Court may, in its discretion, permit discovery
or other pretrial proceedings and may proceed to trial upon the appraisal prior
to the final determination of the stockholder entitled to an appraisal. Any
stockholder whose name appears on the list filed by the surviving or resulting
corporation pursuant to subsection (f) of this section and who has submitted his
certificates of stock to the Register in Chancery, if such is required, may
participate fully in all proceedings until it is finally determined that he is
not entitled to appraisal rights under this section.
 
     (i) The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to the
stockholders entitled thereto. Interest may be simple or compound, as the Court
may direct. Payment shall be so made to each such stockholder, in the case of
holders of uncertificated stock forthwith, and in the case of holders of shares
represented by certificates upon the surrender to the corporation of the
certificates representing such stock. The Court's decree may be enforced as
other decrees in the Court of Chancery may be enforced, whether such surviving
or resulting corporation be a corporation of this State or of any state.
 
     (j) The costs of the proceeding may be determined by the Court and taxed
upon the parties as the Court deems equitable in the circumstances. Upon
application of a stockholder, the court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorneys' fees and
expenses of experts, to be charged pro rata against the value of all the shares
entitled to an appraisal.
 
     (k) From and after the effective date of the merger or consolidation, no
stockholder who has demanded his appraisal rights as provided in subsection (d)
of this section shall be entitled to vote such stock for any purpose or to
receive payment of dividends or other distributions on the stock (except
dividends or other distributions payable to stockholders of record at a date
which is prior to the effective date of the merger or consolidation); provided,
however, that if no petition for an appraisal shall be filed within the time
provided in subsection (e) of this section, or if such stockholder shall deliver
to the surviving or resulting corporation a written withdrawal of his demand of
an appraisal and an acceptance of the merger or consolidation, either within 60
days after the effective date of the merger or consolidation as provided in
subsection (e) of this section or thereafter with the written approval of the
corporation, then the right of such stockholder to an appraisal shall cease.
Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery
shall be dismissed as to any stockholder without the approval of the Court, and
such approval may be conditioned upon such terms as the Court deems just.
 
     (l) The shares of the surviving or resulting corporation to which the
shares of such objecting stockholders would have been converted had they
assented to the merger or consolidation shall have the status of authorized and
unissued shares of the surviving or resulting corporation.

                     INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     The Delaware General Corporation Law and Thermo's Certificate of
Incorporation and By-Laws limit the monetary liability of directors to Thermo
and to its stockholders and provide for indemnification of Thermo's officers and
directors for liabilities and expenses that they may incur in such capacities.
In general, officers and directors are indemnified with respect to actions taken
in good faith in a manner reasonably believed to be in, or not opposed to, the
best interests of Thermo, and with respect to any criminal action or proceeding,
actions that the indemnitee had no reasonable cause to believe were unlawful.
Thermo also has indemnification agreements with its directors and officers that
provide for the maximum indemnification allowed by law. Reference is made to
Thermo's Certificate of Incorporation, By-Laws and form of Indemnification
Agreement for Officers and Directors incorporated by reference as Exhibits 3.1,
3.2 and 10.10 hereto, respectively.
 
     Thermo Electron Corporation has an insurance policy which insures the
directors and officers of Thermo Electron and its subsidiaries, including
Thermo, against certain liabilities which might be incurred in connection with
the performance of their duties.
 
ITEM 21.  EXHIBITS AND FINANCIAL STATEMENT SCHEDULES.
 
     See the Exhibit Index included immediately preceding the exhibits to this
Registration Statement.
 
ITEM 22.  UNDERTAKINGS.
 
     The undersigned Registrant hereby undertakes:
 
          (1) To file, during any period in which offers or sales are being
     made, a post-effective amendment to this registration statement:
 
             (i) To include any prospectus required by Section 10(a)(3) of the
        Securities Act of 1933;
 
             (ii) To reflect in the prospectus any facts or events arising after
        the Effective Time of the registration statement (or the most recent
        post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in the registration statement;
 
             (iii) To include any material information with respect to the plan
        of distribution not previously disclosed in the registration statement
        or any material change to such information in the registration
        statement.
 
          (2) That, for the purpose of determining any liability under the
     Securities Act of 1933, each such post-effective amendment shall be deemed
     to be a new registration statement relating to the securities offered
     therein, and the offering of such securities at that time shall be deemed
     to be the initial bona fide offering thereof.
 
          (3) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.
 
     The undersigned Registrant hereby undertakes as follows: that prior to any
public reofferring of the securities registered hereunder through use of a
prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes that such reofferring prospectus will contain the information
called for by the applicable registration form with respect to reofferrings by
persons who may be deemed to be underwriters, in addition to the information
called for by the other Items of the applicable form.
 
     The undersigned registrant hereby undertakes that every prospectus: (i)
that is filed pursuant to the immediately preceding paragraph, or (ii) that
purports to meet the requirements of Section 10(a)(3) of the
 
                                      II-1
<PAGE>   138
 
Act and is used in connection with an offering of securities subject to Rule
415, will be filed as a part of an amendment to the registration statement and
will not be used until such amendment is effective, and that, for purposes of
determining any liability under the Securities Act of 1933, each such
post-effective amendment shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the Registrant of expenses incurred
or paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

Section 228 of the Delaware General Corporation Law, to the following actions

taken without a meeting, which shall have the same force and effect as if

RESOLVED:       That the shareholders of the Corporation hereby adopt and
                approve the Agreement and Plan of Merger dated as of November
