         WHEREAS, Thermo Electron, as the sole stockholder of Merger Sub, has
approved this Agreement and the Merger; and

         WHEREAS, for United States federal income tax purposes, it is intended
that the Merger shall qualify as a reorganization within the meaning of Section

                                   ARTICLE II

                 EFFECTS OF THE MERGER; EXCHANGE OF CERTIFICATES

         SECTION 2.1. Effect on Capital Stock. Subject to the terms and
conditions of this Agreement, at the Effective Time, by virtue of the Merger and
without any action on the part of Thermo Electron, Merger Sub, Fisher or the
holders of any shares of common stock, par value $0.01 per share, of Fisher
("Fisher Common Stock"):

               (a) Conversion of Fisher Common Stock. Subject to Sections 2.1(f)
and 2.1(g), each share of Fisher Common Stock issued and outstanding immediately
prior to the Effective Time, other than any shares of Fisher Common Stock to be
canceled pursuant to Section 2.1(c), shall be automatically converted into and
become the right to receive 2.0 (the "Exchange Ratio") fully paid and
nonassessable shares of common stock, par value $1.00 per share ("Thermo
Electron Common Stock"), of Thermo Electron (the "Merger Consideration"). As a
result of the Merger, at the Effective Time, each holder of a Certificate (as
defined in Section 2.2(b)) shall cease to have any rights with respect thereto,
except the right to receive the Merger Consideration payable in respect of the
shares of Fisher Common Stock represented by such Certificate immediately prior
to the Effective Time, any cash in lieu of fractional shares payable pursuant to
Section 2.1(f) and any dividends or other distributions payable pursuant to
Section 2.2(c), all to be issued or paid, without interest, in consideration
therefor upon the surrender of such Certificate in accordance with Section
2.2(b) (or, in the case of a lost, stolen or destroyed Certificate, Section
2.2(i)).

               (b) Capital Stock of Merger Sub. Each share of common stock, par
value $0.01 per share, of Merger Sub issued and outstanding immediately prior to
the Effective Time shall be converted into one fully paid and nonassessable
share of common stock, par value $0.01 per share, of the Surviving Corporation.

               (c) Cancellation of Shares. Each share of Fisher Common Stock
owned by Thermo Electron, Merger Sub or Fisher immediately prior to the
Effective Time shall automatically be extinguished without any conversion, and
no consideration shall be delivered in respect thereof.

                                      -4-


               (d) Fisher Options, Stock Unit Awards and Employee Stock Purchase
Plans. At the Effective Time, (i) subject to and in accordance with Section
5.11(a), all options to purchase Fisher Common Stock (each, a "Fisher Option")
and all restricted stock units and rights to receive shares of Fisher Common
Stock or an amount in cash measured by the value of a number of shares of Fisher
Common Stock (each, a "Fisher Stock Unit Awards"), in each case, issued and
outstanding at the Effective Time under a Fisher Stock Plan or a Fisher Deferred
Compensation Plan (each as defined in Section 3.1(b)(i)), shall be assumed by
Thermo Electron and (ii) all rights outstanding under Fisher's Employee Stock
Purchase Plan, as approved by the Fisher stockholders on May 5, 2006 (the
"Fisher Purchase Plan"), shall be treated as set forth in Section 5.11(b).

               (e) Conversion of Debt. The Fisher Convertible Debentures (as
defined in Section 3.1(b)(i)) shall remain outstanding as debentures of Fisher,
however in lieu of being convertible into shares of Fisher Common Stock,
following the Effective Time, the Fisher Convertible Debentures shall become
convertible into Thermo Electron Common Stock at a conversion ratio equal to the
conversion ratio in effect immediately prior to the Effective Time multiplied by
the Exchange Ratio and Thermo Electron shall agree to guarantee the payment of,
or become a co-obligor on, said debentures.

               (f) Fractional Shares. No fraction of a share of Thermo Electron
Common Stock will be issued by virtue of the Merger, but in lieu thereof each
holder of shares of Fisher Common Stock who would otherwise be entitled to a
fraction of a share of Thermo Electron Common Stock (after aggregating all
shares of Thermo Electron Common Stock that otherwise would be received by such
holder) shall, upon surrender of such holder's Certificate or Certificates,
receive from Thermo Electron an amount of cash (rounded to the nearest whole
cent), without interest, equal to the product of: (i) the fractional share
interest (after aggregating all shares of Thermo Electron Common Stock that
would otherwise be received by such holder) which such holder would otherwise
receive, multiplied by (ii) the closing price of one share of Thermo Electron
Common Stock on the New York Stock Exchange ("NYSE") Composite Transactions Tape
ending on the trading day one day prior to the Effective Time.

               (g) Adjustments to Exchange Ratio. The Exchange Ratio and the
Merger Consideration shall be adjusted to reflect fully the appropriate effect
of any stock split, split-up, reverse stock split, stock dividend (including any
dividend or distribution of securities convertible into Thermo Electron Common
Stock or Fisher Common Stock), reorganization, recapitalization,
reclassification or other like change with respect to Thermo Electron Common
Stock or Fisher Common Stock having a record date occurring on or after the date
hereof and prior to the Effective Time.

         SECTION 2.2. Exchange of Shares and Certificates.

               (a) Exchange Agent. At or prior to the Effective Time, Thermo
Electron shall engage an institution reasonably satisfactory to Fisher (and
Thermo Electron's transfer agent shall be deemed satisfactory to Fisher) to act
as exchange agent in connection with the Merger (the "Exchange Agent"), pursuant
to an agreement reasonably satisfactory to Fisher. At the Effective Time, Thermo
Electron shall deposit with the Exchange Agent, in trust for the benefit of the
holders of shares of Fisher Common Stock immediately prior to the Effective

                                      -5-


Time, certificates representing the shares of Thermo Electron Common Stock
issuable pursuant to Section 2.1(a). In addition, Thermo Electron shall make
available by depositing with the Exchange Agent, as necessary from time to time
after the Effective Time, cash in an amount sufficient to make the payments in
lieu of fractional shares pursuant to Section 2.1(f) and any dividends or
distributions to which holders of shares of Fisher Common Stock may be entitled
pursuant to Section 2.2(c). All cash and certificates representing shares of
Thermo Electron Common Stock deposited with the Exchange Agent shall hereinafter
be referred to as the "Exchange Fund."

               (b) Exchange Procedures. Promptly after the Effective Time, and
in any event within 10 business days after the Effective Time, Thermo Electron
shall cause the Exchange Agent to mail to each holder of record of a certificate
or certificates which immediately prior to the Effective Time represented
outstanding shares of Fisher Common Stock (the "Certificates"), which at the
Effective Time were converted into the right to receive the Merger Consideration
pursuant to Section 2.1 hereof, (i) a letter of transmittal (which shall specify
that delivery shall be effected, and that risk of loss and title to the
Certificates shall pass only upon delivery of the Certificates to the Exchange
Agent and which shall be in form and substance reasonably satisfactory to Thermo
Electron and Fisher) and (ii) instructions for use in effecting the surrender of
the Certificates in exchange for certificates representing whole shares of
Thermo Electron Common Stock, cash in lieu of any fractional shares pursuant to
Section 2.1(f) and any dividends or other distributions payable pursuant to
Section 2.2(c). Upon surrender of Certificates for cancellation to the Exchange
Agent, together with such letter of transmittal, duly completed and validly
executed in accordance with the instructions thereto, and such other documents
as may reasonably be required by the Exchange Agent, the holder of such
Certificates shall be entitled to receive in exchange therefor a certificate
representing that number of whole shares of Thermo Electron Common Stock (after
taking into account all Certificates surrendered by such holder) to which such
holder is entitled pursuant to Section 2.1 (which shall be in uncertificated
book entry form unless a physical certificate is requested), payment by cash or
check in lieu of fractional shares which such holder is entitled to receive
pursuant to Section 2.1(f) and any dividends or distributions payable pursuant
to Section 2.2(c), and the Certificates so surrendered shall forthwith be
canceled. In the event of a transfer of ownership of shares of Fisher Common
Stock which is not registered in the transfer records of Fisher, a certificate
representing the proper number of shares of Thermo Electron Common Stock may be
issued to a Person (as defined in Section 8.3(l)) other than the Person in whose
name the Certificate so surrendered is registered, if such Certificate shall be
properly endorsed or otherwise be in proper form for transfer and the Person
requesting such issuance shall pay any transfer or other Taxes (as defined in
Section 3.1(j)(xi)) required by reason of the issuance of shares of Thermo
Electron Common Stock to a Person other than the registered holder of such
Certificate or establish to the reasonable satisfaction of Thermo Electron that
such Tax has been paid or is not applicable. Until surrendered as contemplated
by this Section 2.2(b), each Certificate shall be deemed at any time after the
Effective Time to represent only the right to receive the Merger Consideration
(and any amounts to be paid pursuant to Section 2.1(f) or Section 2.2(c)) upon
such surrender. No interest shall be paid or shall accrue on any amount payable
pursuant to Section 2.1(f) or Section 2.2(c).

               (c) Distributions with Respect to Unexchanged Shares. No
dividends or other distributions with respect to shares of Thermo Electron
Common Stock with a record

                                      -6-


date after the Effective Time shall be paid to the holder of any unsurrendered
Certificate with respect to the shares of Thermo Electron Common Stock
represented thereby, and no cash payment in lieu of fractional shares shall be
paid to any such holder pursuant to Section 2.1(f) hereof, until such
Certificate has been surrendered in accordance with this Article II. Subject to
Applicable Laws, following surrender of any such Certificate, there shall be
paid to the recordholder thereof, without interest, (i) promptly after such
surrender, the number of whole shares of Thermo Electron Common Stock issuable
in exchange therefor pursuant to this Article II, together with any cash payable
in lieu of a fractional share of Thermo Electron Common Stock to which such
holder is entitled pursuant to Section 2.1(f) and the amount of dividends or
other distributions with a record date after the Effective Time theretofore paid
with respect to such whole shares of Thermo Electron Common Stock and (ii) at
the appropriate payment date, the amount of dividends or other distributions
with a record date after the Effective Time and a payment date subsequent to
such surrender payable with respect to such whole shares of Thermo Electron
Common Stock.

               (d) No Further Ownership Rights in Fisher Common Stock. All
shares of Thermo Electron Common Stock issued upon the surrender for exchange
of Certificates in accordance with the terms of this Article II and any
cash paid pursuant to Section 2.1(f) or Section 2.2(c) shall be deemed to have
been issued (or paid) in full satisfaction of all rights pertaining to the
shares of Fisher Common Stock previously represented by such Certificates. After
the Effective Time, the stock transfer books of Fisher shall be closed and there
shall be no further registration of transfers on the stock transfer books of the
Surviving Corporation of the shares of Fisher Common Stock which were
outstanding immediately prior to the Effective Time. If, after the Effective
Time, Certificates are presented to the Surviving Corporation or the Exchange
Agent for any reason, they shall be canceled and exchanged as provided in this
Article II.

               (e) Termination of Exchange Fund. Any portion of the Exchange
Fund which remains undistributed to the holders of Certificates one year after
the Effective Time shall be delivered to Thermo Electron, upon demand, and any
holders of Certificates who have not theretofore complied with this Article II
shall thereafter look only to Thermo Electron for payment of their claim for the
Merger Consideration, any cash in lieu of fractional shares of Thermo Electron
Common Stock pursuant to Section 2.1(f) and any dividends or distributions
pursuant to Section 2.2(c).

               (f) No Liability. None of Thermo Electron, Merger Sub, Fisher or
the Exchange Agent or any of their respective directors, officers, employees and
agents shall be liable to any Person in respect of any shares of Thermo Electron
Common Stock (or dividends or distributions with respect thereto) or cash from
the Exchange Fund delivered to a public official pursuant to any applicable
abandoned property, escheat or similar law. If any Certificate shall not have
been surrendered prior to seven years after the Effective Time, or immediately
prior to such earlier date on which any shares of Thermo Electron Common Stock,
any cash in lieu of fractional shares of Thermo Electron Common Stock or any
dividends or distributions with respect to Thermo Electron Common Stock issuable
in respect of such Certificate would otherwise escheat to or become the property
of any Governmental Entity (as defined in Section 3.1(c)(v)), any such shares,
cash, dividends or distributions in respect of such Certificate shall, to

                                      -7-


the extent permitted by Applicable Laws, become the property of the Surviving
Corporation, free and clear of all claims or interests of any Person previously
entitled thereto.

               (g) Investment of Exchange Fund. The Exchange Agent shall invest
any cash included in the Exchange Fund as directed by Thermo Electron on a daily
basis, provided, that no such investment or loss thereon shall affect the
amounts payable to former stockholders of Fisher after the Effective Time
pursuant to this Article II. Any interest and other income resulting from such
investment shall become a part of the Exchange Fund, and any amounts in excess
of the amounts payable pursuant to this Article II shall promptly be paid to
Thermo Electron.

               (h) Withholding Rights. Thermo Electron and the Exchange Agent
shall be entitled to deduct and withhold from any consideration payable pursuant
to this Agreement to any Person who was a holder of Fisher Common Stock
immediately prior to the Effective Time such amounts as Thermo Electron or the
Exchange Agent may be required to deduct and withhold with respect to the making
of such payment under the Code or any other provision of federal, state, local
or foreign Tax law. To the extent that amounts are so withheld by Thermo
Electron or the Exchange Agent, such withheld amounts shall be treated for all
purposes of this Agreement as having been paid to the Person to whom such
consideration would otherwise have been paid.

               (i) Lost, Stolen or Destroyed Certificates. In the event any
Certificates shall have been lost, stolen or destroyed, the Exchange Agent shall
issue in exchange for such lost, stolen or destroyed Certificates, upon the
making of an affidavit of that fact by the holder thereof, such shares of Thermo
Electron Common Stock as may be required pursuant to Section 2.1(a), cash for
fractional shares pursuant to Section 2.1(f) and any dividends or distributions
payable pursuant to Section 2.2(c); provided, however, that Thermo Electron may,
in its discretion and as a condition precedent to the issuance thereof, require
the owner of such lost, stolen or destroyed Certificates to deliver an agreement
of indemnification in form reasonably satisfactory to Thermo Electron, or a bond
in such sum as Thermo Electron may reasonably direct as indemnity, against any
claim that may be made against Thermo Electron or the Exchange Agent in respect
of the Certificates alleged to have been lost, stolen or destroyed.

                                  ARTICLE III

                         REPRESENTATIONS AND WARRANTIES

         SECTION 3.1. Representations and Warranties of Fisher. Except as set
forth in the disclosure schedule dated as of the date of this Agreement and
executed and delivered by Fisher to Thermo Electron concurrently with or prior
to the execution and delivery by Fisher of this Agreement (the "Fisher
Disclosure Schedule"), Fisher represents and warrants to Thermo Electron and
Merger Sub as set forth in this Section 3.1. Each disclosure set forth in the
Fisher Disclosure Schedule, and any other information included in the Fisher
Disclosure Schedule, is identified by reference to, or has been grouped under a
heading referring to, a specific individual subsection of this Agreement and
shall be deemed to be disclosed solely for purposes of, and shall qualify and be
treated as an exception to, such subsection, except to the extent that
disclosure in one subsection of the Fisher Disclosure Schedule is specifically
referred to in

                                      -8-


another subsection of the Fisher Disclosure Schedule by appropriate
cross-reference and except to the extent that the relevance of a disclosure in
one subsection of the Fisher Disclosure Schedule to another subsection of the
Fisher Disclosure Schedule is reasonably apparent. The parties hereby agree that
no reference to or disclosure of any item or other matter in the Fisher
Disclosure Schedule shall be construed as an admission or indication that (1)
such item or other matter is material, (2) such item or other matter is required
to be referred to or disclosed in the Fisher Disclosure Schedule or (3) any
breach or violation of Applicable Laws or any Contract (as defined in Section
8.3(c)) exists or has actually occurred.

               (a) Organization, Standing and Corporate Power; Charter
Documents; Subsidiaries.

                   (i) Organization, Standing and Corporate Power. Fisher and
      each of its Subsidiaries (as defined in Section 8.3(m)) is a corporation
      or other legal entity duly organized, validly existing and in good
      standing (with respect to jurisdictions which recognize such concept)
      under the laws of the jurisdiction in which it is incorporated or
      otherwise organized and has the requisite corporate (or similar) power and
      authority and all necessary government approvals to own, lease and operate
      its properties and to carry on its business as currently conducted, except
      for those jurisdictions in which the failure to have such power, authority
      or government approvals and to be so organized, existing or in good
      standing would not, individually or in the aggregate, reasonably be
      expected to have a Material Adverse Effect (as defined in Section 8.3(i))
      on Fisher and its Subsidiaries, taken as a whole. Each of Fisher and each
      of its Subsidiaries is duly qualified or licensed to do business and is in
      good standing (with respect to jurisdictions which recognize such concept)
      in each jurisdiction in which the nature or conduct of its business or the
      ownership, leasing or operation of its properties makes such
      qualification, licensing or good standing necessary, except for those
      jurisdictions where the failure to be so qualified or licensed or to be in
      good standing would not, individually or in the aggregate, reasonably be
      expected to have a Material Adverse Effect on Fisher and its Subsidiaries,
      taken as a whole.

                   (ii) Charter Documents. Fisher has delivered or made
      available to Thermo Electron prior to the execution of this Agreement
      complete and correct copies of (A) the Amended and Restated Certificate of
      Incorporation of Fisher (including any certificates of designation), as
      amended and currently in effect (the "Fisher Charter"), and the By-Laws of
      Fisher, as amended and currently in effect (the "Fisher By-Laws," and,
      together with the Fisher Charter, the "Fisher Organizational Documents")
      and (B) the articles or certificate of incorporation and By-Laws or like
      organizational documents of each of the Fisher Material Subsidiaries (as
      defined in Section 3.1(a)(iii)), as amended and currently in effect
      (collectively, the "Fisher Subsidiary Organizational Documents"), and each
      such instrument is in full force and effect. Fisher is not in material
      violation of the Fisher Organizational Documents and no Fisher Material
      Subsidiary is in material violation of its Fisher Subsidiary
      Organizational Documents.

                   (iii) Subsidiaries. Section 3.1(a)(iii) of the Fisher
      Disclosure Schedule lists all the Subsidiaries of Fisher which, as of the
      date of this Agreement, have annual gross revenues in excess of
      $200,000,000 (the "Fisher Material Subsidiaries").

      interests in, each Fisher Material Subsidiary have been validly issued and
      are fully paid and nonassessable and are owned directly or indirectly by
      Fisher, free and clear of all mortgages, pledges, claims, restrictions,
      infringements, liens, charges, encumbrances and security interests and
      claims of any kind or nature whatsoever (collectively, "Liens") and free
      of any other restriction (including preemptive rights and any restriction
      on the right to vote, sell or otherwise dispose of such capital stock or

      Deferred Compensation Plans"), complete and correct copies of which, in
      each case as amended, have been filed as exhibits to the Fisher SEC
      Documents (as defined in Section 3.1(d)(i)) prior to the date of this
      Agreement or made available to Thermo Electron. Each outstanding share of

      of them is bound obligating Fisher or any of its Subsidiaries to issue,
      deliver or sell, or cause to be issued, delivered or sold, additional
      shares of capital stock, Voting Debt or other voting securities of Fisher
      or any of its Subsidiaries, or obligating Fisher or any of its
      Subsidiaries to issue, grant, extend or enter into any such security,
      option, warrant, call, right, commitment, agreement, arrangement or
      undertaking. All outstanding shares of Fisher Common Stock, all
      outstanding Fisher Options and Fisher Stock Unit Awards and all
      outstanding shares of capital stock of each Subsidiary of Fisher have been
      issued and granted in compliance in all material respects with (A) all
      applicable securities laws and all other Applicable Laws and (B) all
      requirements set forth in applicable material Contracts.

                   (v) Since December 31, 2005, and through the date hereof,

      Subsidiary of Fisher and other than loans made in the ordinary course
      consistent with past practice to employees of Fisher and its Subsidiaries.

      authority to enter into this Agreement, to perform its obligations

      Fisher, and no other corporate proceedings on the part of Fisher and no

      consummate the transactions contemplated hereby, other than, with respect
      to approval of this Agreement and the Merger, the Fisher Stockholder
      Approval (as defined in Section 3.1(c)(iii)). This Agreement has been duly
      executed and delivered by Fisher. Assuming the due authorization,
      execution and delivery of this Agreement by Thermo Electron and Merger
      Sub, this Agreement constitutes the legal, valid and binding obligation of
      Fisher enforceable against Fisher in accordance with their terms, subject
      to applicable bankruptcy, insolvency, reorganization, moratorium or other
      laws relating to or affecting the rights and remedies of creditors
      generally and to general principles of equity (regardless of whether
      considered in a proceeding in equity or at law).

                   (ii) Board Approval. The Board of Directors of Fisher has (A)
      determined that this Agreement and the Merger are advisable and fair to
      and in the best interests of Fisher and its stockholders, (B) duly
      approved and adopted this Agreement, the Merger and the other transactions
      contemplated hereby, which adoption has not been rescinded or modified,
      (C) resolved to recommend this Agreement and the Merger to its
      stockholders for approval, and (D) subject to Section 5.1(b) directed that

      submitted to Fisher's stockholders for consideration and adoption at a
      duly held meeting of such stockholders in accordance with this Agreement.

                   (iii) Voting Requirements. The affirmative vote of holders of
      a majority of the outstanding shares of Fisher Common Stock entitled to
      vote is the only vote of the holders of any class or series of Fisher
      capital stock necessary to approve and adopt this Agreement, approve the
      Merger and consummate the Merger and the other transactions contemplated
      hereby.

                   (iv) No Conflict. Except as set forth in Section 3.1(c)(iv)
      of the Fisher Disclosure Schedule, the execution and delivery of this
      Agreement by Fisher do not, and the consummation by Fisher of the
      transactions contemplated hereby and compliance by Fisher with the
      provisions of this Agreement will not, conflict with, result in any
      violation or breach of or default (with or without notice or lapse of
      time, or both) under, require any consent, waiver or approval under, give
      rise to any right of termination or cancellation or acceleration of any
      right or obligation or loss of a benefit under, or result in the creation
      of any Lien upon any of the properties or assets of Fisher or any of its
      Subsidiaries or any restriction on the conduct of Fisher's business or
      operations under, (A) the Fisher Organizational Documents or the Fisher
      Subsidiary Organizational Documents, (B) any Contract to which Fisher or
      any Fisher Subsidiary is a party or

      such conflicts, violations, defaults, rights, losses, restrictions or
      Liens, or failure to obtain consents, waivers or approvals, which,

                                      -13-


                       (D) the Fisher Stockholder Approval;

                       (E) the consents, approvals, orders or authorizations set
            forth in Section 3.1(c)(v)(E) of the Fisher Disclosure Schedule; and

                       (F) other such consents, approvals, orders or
            authorizations, the failure of which to be made or obtained,
            individually or in the aggregate, would not reasonably be expected
            to have a Material Adverse Effect on Fisher and its Subsidiaries,
            taken as a whole.

               (d) SEC Documents; Financial Statements.

                   (i) Fisher has filed with the SEC all registration
      statements, prospectuses, reports, schedules, forms, statements,
      certifications and other documents (including exhibits and all other
      information incorporated by reference therein) presently required to be so
      filed by Fisher since January 1, 2004 (excluding the Joint Proxy
      Statement, the "Fisher SEC Documents"). As of their respective dates, the
      Fisher SEC Documents complied in all material respects with the
      requirements of the Securities Act of 1933, as amended (the "Securities
      Act"), or the Exchange Act, as the case may be, to the extent in effect,
      the Sarbanes-Oxley Act of 2002 ("SOX") and the rules and regulations of
      the SEC promulgated thereunder applicable to such Fisher SEC Documents,
      and none of the Fisher SEC Documents, when filed, contained any untrue
      statement of a material fact or omitted to state a material fact required
      to be stated therein or necessary in order to make the statements therein,
      in light of the circumstances under which they were made, not misleading,
      except to the extent corrected by a subsequently filed Fisher SEC Document
      filed with the SEC prior to the date hereof. No Subsidiary of Fisher is
      subject to the periodic reporting requirements of the Exchange Act.

                   (ii) Each of the principal executive officer of Fisher and
      the principal financial officer of Fisher (or each former principal
      executive officer of Fisher and each former principal financial officer of
      Fisher, as applicable) has made all certifications required by Rule 13a-14
      or 15d-14 under the Exchange Act or Sections 302 and 906 of SOX and the
      rules and regulations of the SEC promulgated thereunder with respect to
      the Fisher SEC Documents. For purposes of the preceding sentence,
      "principal executive officer" and "principal financial officer" shall have
      the meanings given to such terms in SOX. Neither Fisher nor any of its
      Subsidiaries has outstanding, or has arranged any outstanding, "extensions
      of credit" to directors or executive officers within the meaning of
      Section 402 of SOX.

                   (iii) The financial statements of Fisher included in the
      Fisher SEC Documents, including each Fisher SEC Document filed after the
      date hereof until the Effective Time, comply, as of their respective dates
      of filing with the SEC, in all material respects with applicable
      accounting requirements and the published rules and regulations of the SEC
      with respect thereto, have been prepared in accordance with United States
      generally accepted accounting principles ("GAAP") (except, in the case of
      unaudited statements, as permitted by Form 10-Q or 8-K or other applicable
      rules of the SEC) applied on a consistent basis during the periods
      involved (except as may be

                                      -14-


      indicated in the notes thereto) and fairly present the consolidated
      financial position of Fisher and its consolidated Subsidiaries as of the
      dates thereof and the consolidated results of their operations and cash
      flows for the periods then ended (subject, in the case of unaudited
      statements, to normal year-end audit adjustments which are not material).
      The financial books and records of Fisher and its Subsidiaries, taken as a
      whole, are true and correct in all material respects.

                   (iv) Except as reflected or reserved against in the balance
      sheet of Fisher, dated December 31, 2005, included in the Form 10-K filed
      by Fisher with the SEC on February 21, 2006 (including the notes thereto,
      the "Fisher Balance Sheet") and except as set forth in Section 3.1(d)(iv)
      of the Fisher Disclosure Schedule, neither Fisher nor any of its
      Subsidiaries has any liabilities or obligations of any nature (whether
      absolute, accrued, known or unknown, contingent or otherwise) nor, to the
      Knowledge (as defined in Section 8.3(h)) of Fisher, does any basis exist
      therefor, other than liabilities or obligations that (A) were incurred
      since January 1, 2006 in the ordinary course of business consistent with
      past practice and individually or in the aggregate, have not had and would
      not reasonably be expected to have a Material Adverse Effect on Fisher and
      its Subsidiaries, taken as a whole, (B) individually or in the aggregate,
      have not had and would not reasonably be expected to have a Material
      Adverse Effect on Fisher and its Subsidiaries, taken as a whole or (C)
      were incurred pursuant to this Agreement or the transactions contemplated
      hereby.

                   (v) Neither Fisher nor any of its Subsidiaries is a party to,
      or has any commitment to become a party to, any joint venture, off-balance
      sheet partnership or any similar contract or arrangement (including
      without limitation any contract or arrangement relating to any transaction
      or relationship between or among Fisher and any of its Subsidiaries, on
      the one hand, and any unconsolidated Affiliate (as defined in Section
      8.3(a)), including without limitation any structured finance, special
      purpose or limited purpose entity or Person, on the other hand, or any
      "off-balance sheet arrangement" (as defined in Item 303(a) of Regulation
      S-K of the SEC)), where the result, purpose or intended effect of such
      contract or arrangement is to avoid disclosure of any material transaction
      involving, or material liabilities of, Fisher or any of its Subsidiaries
      in Fisher's or such Subsidiary's published financial statements or other
      Fisher SEC Documents.

                   (vi) No "material contract" (as such term is defined in Item
      601(b)(10) of Regulation S-K of the SEC) filed as an exhibit to the Fisher
      Form 10-K has been amended or modified, except for amendments or
      modifications which have been filed as an exhibit to a subsequently dated
      Fisher SEC Document or are not required to be filed with the SEC.

               (e) Information Supplied. None of the information supplied or to
be supplied by or on behalf of Fisher for inclusion or incorporation by
reference in (i) the registration statement on Form S-4 to be filed with the SEC
by Thermo Electron in connection with the issuance of Thermo Electron Common
Stock in the Merger (including any amendments or supplements, the "Form S-4")
will, at the time the Form S-4 becomes effective under the Securities Act,
contain any untrue statement of a material fact or omit to state any material
fact

                                      -15-


required to be stated therein or necessary to make the statements therein not
misleading or (ii) the Joint Proxy Statement will, at the date it is first
mailed to Fisher's stockholders or at the time of the Fisher Stockholders'
Meeting, 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 Joint Proxy Statement and the Form S-4 will comply as to form in
all material respects with the requirements of the Securities Act and the
Exchange Act and the rules and regulations thereunder. Notwithstanding the
foregoing provisions of this Section 3.1(e), no representation or warranty is
made by Fisher with respect to information or statements made or incorporated by
reference in the Form S-4 or the Joint Proxy Statement which were not supplied
by or on behalf of Fisher.

               (f) Absence of Certain Changes or Events.

                   (i) Since January 1, 2006 through the date hereof, except as
      and to the extent disclosed in the Fisher SEC Documents filed prior to the
      date of this Agreement and except for liabilities incurred pursuant to
      this Agreement or the transactions contemplated hereby:

                       (A) Fisher and its Subsidiaries have conducted their
            business only in the ordinary course consistent with past practice;

                       (B) there has not been any split, combination or
            reclassification of any of Fisher's capital stock or any
            declaration, setting aside or payment of any dividend on, or other
            distribution (whether in cash, stock or property) in respect of, in
            lieu of or in substitution for, shares of Fisher's capital stock;

                       (C) except as required by a change in GAAP, there has not
            been any change in accounting methods, principles or practices by
            Fisher; and

                       (D) there has not been any action taken by Fisher or any
            of its Subsidiaries that, if taken during the period from the date
            of this Agreement through the Effective Time, would constitute a
            breach of Section 4.1(a), other than actions in connection with
            entering into this Agreement.

                   (ii) Since January 1, 2006 through the date hereof, there
      have not been any changes, circumstances or events that, individually or
      in the aggregate, have had, or would reasonably be expected to have, a
      Material Adverse Effect on Fisher and its Subsidiaries, taken as a whole.

               (g) Compliance with Applicable Laws; Permits; Litigation.

                   (i) Fisher, its Subsidiaries and employees hold all
      authorizations, permits, licenses, certificates, easements, concessions,
      franchises, variances, exemptions, orders, consents, registrations,
      approvals and clearances of all Governmental Entities (including all
      authorizations under the Federal Food, Drug and Cosmetic Act of 1938, as
      amended (the "FDCA"), and the regulations of the U.S. Food

                                      -16-


      and Drug Administration (the "FDA") promulgated thereunder) and third
      Persons which are required for Fisher and its Subsidiaries to own, lease
      and operate its properties and other assets and to carry on their
      respective businesses in the manner described in the Fisher SEC Documents
      filed prior to the date hereof and as they are being conducted as of the
      date hereof (the "Fisher Permits"), and all Fisher Permits are valid and
      in full force and effect, except where the failure to have, or the
      suspension or cancellation of, or the failure to be valid or in full force
      and effect of, any such Fisher Permits, individually or in the aggregate,
      would not reasonably be expected to have a Material Adverse Effect on
      Fisher and its Subsidiaries, taken as a whole.

                   (ii) Fisher and its Subsidiaries are, and have been at all
      times since January 1, 2004, in compliance with the terms of the Fisher
      Permits and all laws, statutes, orders, rules, regulations, policies or
      guidelines promulgated, or judgments, decisions or orders entered by any
      Governmental Entity (all such laws, statutes, orders, rules, regulations,
      policies, directives, guidelines, judgments, decisions and orders,
      collectively, "Applicable Laws") relating to Fisher and its Subsidiaries
      or their respective businesses, assets or properties, except where the
      failure to be in compliance with the terms of the Fisher Permits or such
      Applicable Laws, individually or in the aggregate, would not reasonably be
      expected to have a Material Adverse Effect on Fisher and its Subsidiaries,
      taken as a whole. Since January 1, 2004, neither Fisher nor any of its
      Subsidiaries has received any written notification from any Governmental
      Entity (A) asserting that Fisher or any of its Subsidiaries is not in
      compliance with, or at any time since such date has failed to comply with,
      Applicable Laws (except for any such lack of compliance which,
      individually or in the aggregate, would not reasonably be expected to have
      a Material Adverse Effect on Fisher and its Subsidiaries, taken as a
      whole) or (B) threatening to revoke any Fisher Permit (except for any such
      revocation which, individually or in the aggregate, would not reasonably
      be expected to have a Material Adverse Effect on Fisher and its
      Subsidiaries, taken as a whole) nor, to the Knowledge of Fisher, does any
      basis exist therefor. As of the date hereof, no investigation or review by
      any Governmental Entity is pending or, to the Knowledge of Fisher, has
      been threatened in writing against Fisher or any of its Subsidiaries
      which, individually or in the aggregate, would reasonably be expected to
      have a Material Adverse Effect on Fisher and its Subsidiaries, taken as a
      whole.

                   (iii) Fisher is, and has been, in compliance in all material
      respects with the provisions of SOX applicable to it.

                   (iv) Except as and to the extent disclosed in the Fisher SEC
      Documents filed prior to the date of this Agreement, including the notes
      to the financial statements included therein, no action, audit, demand,
      claim, suit, proceeding, requirement or investigation by any Governmental
      Entity, and no suit, action, mediation, arbitration or proceeding by any
      Person, against or affecting Fisher or any of its Subsidiaries or any of
      their respective properties, including Intellectual Property (as defined
      in Section 8.3(g)), is pending or, to the Knowledge of Fisher, threatened
      which, individually or in the aggregate, would reasonably be expected to
      have a Material Adverse Effect on Fisher and its Subsidiaries, taken as a
      whole.

                                      -17-


                   (v) Neither Fisher nor any of its Subsidiaries is, or at any
      time since January 1, 2004 has been, subject to any outstanding order,
      injunction or decree which, individually or in the aggregate, has had or
      would reasonably be expected to have a Material Adverse Effect on Fisher
      and its Subsidiaries, taken as a whole.

               (h) Labor and Other Employment Matters.

                   (i) Except as would not, individually or in the aggregate,
      reasonably be expected to have a Material Adverse Effect on Fisher, its
      Subsidiaries, taken as a whole (A) no work stoppage, slowdown, lockout,
      labor strike, material arbitrations or other material labor disputes
      against Fisher or any of its Subsidiaries are pending or, to the Knowledge
      of Fisher, threatened, (B) no unfair labor practice charges, grievances or
      complaints are pending or, to the Knowledge of Fisher, threatened against
      Fisher or any of its Subsidiaries, (C) neither Fisher nor any of its
      Subsidiaries is delinquent in payments to any of its employees for any
      wages, salaries, commissions, bonuses or other direct compensation for any
      services performed for it or amounts required to be reimbursed to such
      employees, (D) neither Fisher nor any of its Subsidiaries is liable for
      any payment to any trust or other fund or to any Governmental Entity with
      respect to unemployment compensation benefits, social security or other
      benefits or obligations for employees, (E) no employee of Fisher, at the
      officer level or above, has given written notice to Fisher or any of its
      Subsidiaries that any such employee intends to terminate his or her
      employment with Fisher or any of its Subsidiaries, (F) to the Knowledge of
      Fisher, no employee of Fisher or any of its Subsidiaries is in any respect
      in violation of any term of any employment contract, nondisclosure
      agreement, common law nondisclosure obligations, non-competition
      agreement, or any restrictive covenant to a former employer relating to
      the right of any such employee to be employed by Fisher or any of its
      Subsidiaries because of the nature of the business conducted or presently
      proposed to be conducted by Fisher or any of its Subsidiaries or to the
      use of trade secrets or proprietary information of others, (G) neither
      Fisher nor any of its Subsidiaries is a party to, or otherwise bound by,
      any consent decree with, or citation by, any Governmental Entity relating
      to employees or employment practices and (H) Fisher and its Subsidiaries
      are in compliance with all Applicable Laws, agreements, contracts,
      policies, plans and programs relating to employment, employment practices,
      compensation, benefits, hours, terms and conditions of employment and the
      termination of employment, including but not limited to any obligations
      pursuant to the Worker Adjustment and Retraining Notification Act of 1988,
      as amended (the "WARN Act"), or any other comparable Applicable Law.

                   (ii) As of the date hereof,

                       (A) neither Fisher nor any of its Subsidiaries is a party
            to, or otherwise bound by, any collective bargaining agreement or
            any other agreement, work rules or practices with a labor union,
            labor organization or works council, which, in the case of any
            non-U.S. agreement, work rules or practices with a labor union,
            labor organization or works council are material to Fisher and its
            Subsidiaries, taken as a whole, nor are any such agreements, work
            rules or practices presently being negotiated;

                                      -18-


                       (B) no employee of Fisher or any of its Subsidiaries is
            represented by any labor union, labor organization or works council
            in his or her capacity as an employee of Fisher or any of its
            Subsidiaries;

                       (C) no labor union, labor organization or works council
            or group of employees of Fisher or any of its Subsidiaries has made
            a pending demand for recognition or certification to Fisher or any
            of its Subsidiaries, and there are no representation or
            certification proceedings or petitions seeking a representation
            proceeding presently pending or, to the Knowledge of Fisher,
            threatened to be brought or filed with the National Labor Relations
            Board ("NLRB") or any other comparable foreign, state or local labor
            relations tribunal or authority; and

                       (D) to the Knowledge of Fisher, no labor union, labor
            organization or works council is seeking to organize or represent
            any employees of Fisher or any of its Subsidiaries.

               (i) Benefit Plans.

                   (i) Section 3.1(i)(i)(A) of the Fisher Disclosure Schedule
      sets forth a true and complete list of each material bonus, pension,
      profit sharing, deferred compensation, incentive compensation, stock
      ownership, stock purchase, stock option or other equity compensation,
      phantom stock, stock-related or performance award, retirement, vacation,
      severance or termination pay, change in control, retention, disability,
      death benefit, hospitalization, medical, life insurance, loan, disability,
      and other similar material plan, arrangement, agreement or understanding,
      including, without limitation, each "employee benefit plan" (or similar
      plan) within the meaning of Section 3(3) of the Employee Retirement Income
      Security Act of 1974, as amended ("ERISA") or any other comparable
      Applicable Law, whether or not subject to ERISA or such comparable
      Applicable Law, and any material employment agreement, consulting
      agreement, termination or severance agreement (such plans, agreements,
      arrangements or understandings, except any plan which is a Multiemployer
      Plan (as defined in Section 8.3(j)), collectively, "Benefit Plans") with
      or for the benefit of any current or former employee, officer or director
      of Fisher or any of its Subsidiaries or ERISA Affiliates (as defined in
      Section 3.1(i)(v)) or with respect to which Fisher or any of its
      Subsidiaries or ERISA Affiliates have any material obligations or
      liabilities, including each material Benefit Plan that has been adopted or
      maintained by Fisher, any of its Subsidiaries or any Affiliate, whether
      formally or informally, or with respect to which Fisher, any of its
      Subsidiaries or any Affiliate will or may have any material liability, for
      the benefit of employees or consultants of Fisher or any of its
      Subsidiaries who perform services outside the United States (collectively,
      the "Fisher Benefit Plans"). With respect to the Fisher Benefit Plans, no
      event has occurred, and there exists no condition or set of circumstances,
      which would reasonably be expected to have a Material Adverse Effect on
      Fisher and its Subsidiaries, taken as a whole, under ERISA, the Code or
      any other Applicable Laws. Neither Fisher, nor any of its Subsidiaries,
      nor, to the Knowledge of Fisher, any other Person, has any express
      commitment, whether legally enforceable or not, to modify, change or
      terminate any Fisher Benefit Plan, other than with respect to a

                                      -19-


      modification, change or termination required by ERISA or the Code, or any
      other Applicable Law or administrative changes that do not increase the
      liabilities or obligations under any such plans. Fisher has delivered or
      made available to Thermo Electron true, correct and complete copies of all
      Fisher Benefit Plans and, with respect thereto, if applicable, all
      amendments, trust agreements, insurance contracts, other funding vehicles,
      determination letters issued by the Internal Revenue Service (the "IRS"),
      the most recent annual reports (Form 5500 series) filed with the IRS and
      the most recent actuarial report or other financial statement relating to
      such Fisher Benefit Plan.

                   (ii) Each Fisher Benefit Plan has been, in all material
      respects, administered and operated in accordance with its terms, with the
      applicable provisions of ERISA, the Code and other Applicable Laws and
      with the terms of all applicable collective bargaining agreements. Each
      Fisher Benefit Plan, including any material amendments thereto, that is
      required to obtain approval by, or registration or qualification for
      special tax status with, the appropriate taxation, social security or
      supervisory authorities in the relevant country, state, territory or the
      like (each, an "Approval") has received such Approval (or there remains a
      period of time in which to obtain such Approval retroactive to the date of
      any material amendment that has not previously received such Approval),
      and no event has occurred which would reasonably be expected to result in
      the revocation of such Approval or the imposition of material sanctions by
      such authorities. Without limiting the generality of the foregoing, each
      Fisher Benefit Plan that is intended to be qualified under Section 401(a)
      of the Code has obtained a favorable determination letter from the IRS
      that the Fisher Benefit Plan is so qualified and all related trusts are
      exempt from U.S. federal income taxation under Section 501(a) of the Code,
      and, to the Knowledge of Fisher, nothing has occurred, whether by action
      or by failure to act, which would reasonably be expected to cause the loss
      of such qualification or exemption.

                   (iii) As of the date hereof to the Knowledge of Fisher, no
      oral or written representation or commitment with respect to any material
      aspect of any Fisher Benefit Plan has been made to an employee or former
      employee of Fisher or any of its Subsidiaries by an authorized Fisher
      employee that is not materially in accordance with the written or
      otherwise pre-existing terms and provisions of such Fisher Benefit Plans.
      As of the date hereof, to the Knowledge of Fisher, neither Fisher nor any
      of its Subsidiaries has entered into any agreement, arrangement or
      understanding, whether written or oral, with any trade union, works
      council or other employee representative body or any material number or
      category of its employees which would prevent, restrict or materially
      impede the implementation of any layoff, redundancy, severance or similar
      program within its or their respective workforces (or any part of them).

                   (iv) There are no material unresolved claims or disputes
      under the terms of, or in connection with, any Fisher Benefit Plan (other
      than routine undisputed claims for benefits), and no action, legal or
      otherwise, has been commenced or threatened with respect to any material
      claim or otherwise in connection with a Fisher Benefit Plan.

                                      -20-


                   (v) With respect to each Funded Retirement Plan (as defined
      in this Section 3.1(i)(v)) of Fisher or any of its Subsidiaries, the
      aggregate fair market value of the assets of such Funded Retirement Plan
      was, as of the most recently computed actuarial valuation of such plan,
      equal to or greater than the aggregate value of its liabilities assessed
      on an ongoing basis and calculated in accordance with the actuarial
      methods and assumptions used in such valuation pursuant to such Funded
      Retirement Plan and Applicable Law and GAAP. For purposes of this
      Agreement, "Funded Retirement Plan" means, with respect to a party, a
      Benefit Plan that is a "pension plan" within the meaning of Section 3(2)
      of ERISA that is subject to ERISA and under which the assets to satisfy
      the benefit obligations are legally segregated from the general assets of
      such party or any of its Subsidiaries and are not subject to the creditors
      of such party or any of its Subsidiaries. None of Fisher or any other
      Person or entity under common control within the meaning of Section
      414(b), (c), (m) or (o) of the Code (an "ERISA Affiliate") with Fisher has
      incurred, or is reasonably expected to incur, any liability to a Funded
      Retirement Plan under Title IV of ERISA (other than for contributions not
      yet due) or to the Pension Benefit Guaranty Corporation (other than for
      payment of premiums not yet due) that, when aggregated with other such
      liabilities, would reasonably be expected to result in a material
      liability of Fisher and its Subsidiaries, taken as a whole, which
      liability has not been fully paid.

                   (vi) Section 3.1(i)(vi) of the Fisher Disclosure Schedule
      sets forth a true and complete list of each Multiemployer Plan to which
      Fisher or any ERISA Affiliate of Fisher contributes or is required to
      contribute, or to which, or with respect to which, Fisher or any ERISA
      Affiliate of Fisher has any material liability. If any Fisher
      Multiemployer Plan is subject to Title IV of ERISA, then, (A) neither
      Fisher nor any ERISA Affiliate of Fisher has made or suffered a "complete
      withdrawal" or a "partial withdrawal," as such terms are respectively
      defined in Sections 4203 and 4205 of ERISA (or any liability resulting
      therefrom has been satisfied in full), (B) no event has occurred that
      presents a material risk of a complete or partial withdrawal, (C) neither
      Fisher nor any ERISA Affiliate of Fisher has any contingent liability
      under Section 4204 of ERISA, (D) no circumstances exist that present a
      material risk that any such plan will go into reorganization, and (E) to
      the best of Fisher's Knowledge, the aggregate withdrawal liability of
      Fisher and each ERISA Affiliate of Fisher computed as if a complete
      withdrawal by Fisher and any ERISA Affiliate of Fisher had occurred under
      each such Fisher Benefit Plan on the date hereof, would not reasonably be
      expected to result in a material liability to Fisher. No Fisher Benefit
      Plan subject to ERISA is a plan that has two or more contributing sponsors
      at least two of whom are not under common control, within the meaning of
      Section 4063 of ERISA.

                   (vii) No Fisher Benefit Plan provides health benefits
      (whether or not insured) with respect to employees or former employees of
      Fisher or any of its Subsidiaries after retirement or other termination of
      service (other than coverage mandated by Applicable Laws or benefits, the
      full cost of which is borne by the employee or former employee).

                   (viii) Neither the negotiation and execution of this
      Agreement nor the consummation of the transactions contemplated hereby
      will (either alone or upon

                                      -21-


      the occurrence of any additional or subsequent events) constitute an event
      under any Fisher Benefit Plan (for this purpose, Fisher Benefit Plan
      (other than with respect to those Plans that are Fisher Foreign Plans)
      shall be determined without regard to whether any plan, agreement, policy,
      understanding or arrangement is material despite the use of such qualifier
      in Section 3.1(i)(i) for purposes of the definitions of Benefit Plan and
      Fisher Benefit Plan) that will or may result in any payment (whether of
      severance pay or otherwise), acceleration of payment, forgiveness of
      indebtedness, vesting, distribution, increase in benefits or obligation to
      fund benefits with respect to any employee or former employee of Fisher or
      any of its Subsidiaries or limit the ability to amend, terminate or
      receive a reversion of assets from any Fisher Benefit Plan or related
      trust. There is no contract, agreement, plan or arrangement with an
      employee or former employee of Fisher to which Fisher or any of its
      Subsidiaries is a party as of the date of this Agreement that,
      individually or collectively and as a result of the transaction
      contemplated hereby (whether alone or upon the occurrence of any
      additional or subsequent events) would reasonably be expected to give rise
      to the payment of any amount that would not be deductible pursuant to
      Sections 280G or 162(m) of the Code.

                   (ix) Except as would not, individually or in the aggregate,
      reasonably be expected to have a Material Adverse Effect on Fisher and its
      Subsidiaries, taken as a whole, with respect to each Fisher Benefit Plan
      established or maintained outside of the United States for the benefit of
      employees of Fisher or any Subsidiary of Fisher residing outside the
      United States (each, a "Fisher Foreign Plan"): (i) each Fisher Foreign
      Plan is in compliance with the applicable provisions of the laws and
      regulations regarding employee benefits, mandatory contributions and
      retirement plans of each jurisdiction applicable to such Fisher Foreign
      Plan; (ii) each Fisher Foreign Plan required to be registered has been
      registered and has been maintained in good standing with applicable
      regulatory authorities and (iii) the fair market value of the assets of
      each funded Fisher Foreign Plan, the liability of each insurer for any
      Fisher Foreign Plan funded through insurance or the book reserve
      established for any Fisher Foreign Plan, together with any accrued
      contributions, is sufficient to procure or provide for the accrued benefit
      obligations, as of the Closing Date, with respect to all current and
      former participants in such plan according to the actuarial assumptions
      and valuations most recently used to determine employer contributions to
      such Fisher Foreign Plan and no transaction contemplated by this Agreement
      shall cause such assets or insurance obligations to be less than such
      benefit obligations, and any and all amounts required to be accrued with
      respect to any Fisher Foreign Plan or pursuant to any statutory
      requirements pertaining to employee benefits, mandatory contributions,
      retirement plans or similar benefits, have been properly and timely
      accrued, including accruals relating to any severance, termination pay or
      profit sharing benefits.

               (j) Taxes. Except as would not, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect on Fisher and its
Subsidiaries, taken as a whole:

                   (i) Each of Fisher and its Subsidiaries has (A) duly and
      timely filed (or there have been filed on its behalf) all Tax Returns (as
      defined in Section 3.1(j)(xi)) required to be filed by it (taking into
      account all applicable extensions) with

                                      -22-


      the appropriate Tax Authority (as defined in Section 3.1(j)(xi)) and all
      such Tax Returns are true, correct and complete, (B) timely paid in full
      all Taxes (as defined in Section 3.1(j)(xi)) required to be paid by it and
      (C) made adequate provision in accordance with GAAP (or there has been
      paid or provision has been made on its behalf) for the payment of all
      Taxes not yet due and (D) complied with all Applicable Laws relating to
      the payment and withholding of Taxes.

                   (ii) There are no Liens for Taxes upon any property or assets
      of Fisher or any of its Subsidiaries, except for Liens for Taxes not yet
      due and payable or for which adequate reserves have been provided in
      accordance with GAAP in the most recent financial statements contained in
      the Fisher SEC Documents filed prior to the date of this Agreement.

                   (iii) The most recent financial statements contained in the
      Fisher SEC Documents reflect an adequate (A) reserve in accordance with
      GAAP for all Tax liabilities of Fisher and its Subsidiaries for all
      taxable periods and portions thereof accrued through the date of such
      financial statements and (B) valuation allowance in accordance with GAAP
      for all deferred tax assets of Fisher and its Subsidiaries for all taxable
      periods and portions thereof accrued through the date of such financial
      statements.

                   (iv) There is no audit, examination, deficiency, refund
      litigation, proposed adjustment or matter in controversy with respect to
      any Taxes or Tax Return of Fisher or any of its Subsidiaries. Neither
      Fisher nor any of its Subsidiaries has received written notice of any
      claim made by a Governmental Entity in a jurisdiction where Fisher or any
      of its Subsidiaries, as applicable, does not file a Tax Return, that
      Fisher or such Subsidiary is or may be subject to taxation by that
      jurisdiction.

                   (v) The Tax Returns of Fisher and each of its Subsidiaries,
      including any predecessors thereof, have been examined by the applicable
      Tax Authority (or the applicable statutes of limitations for the
      assessment of income Taxes for such periods have expired) for all periods
      through and including December 31, 2003, and no deficiencies were asserted
      as a result of such examinations which have not been resolved and fully
      paid or accrued as a liability on the most recent financial statements
      contained in the Fisher SEC Documents.

                   (vi) There are no outstanding requests, agreements, consents
      or waivers to extend the statutory period of limitations applicable to the
      assessment of any Taxes or deficiencies against Fisher or any of its
      Subsidiaries, and no power of attorney granted by either Fisher or any of
      its Subsidiaries with respect to any Taxes is currently in force.

                   (vii) Neither Fisher nor any of its Subsidiaries is a party
      to any agreement providing for the allocation, indemnification or sharing
      of Taxes (other than any agreements solely between or among Fisher and its
      Subsidiaries), and neither Fisher nor any of its Subsidiaries (A) has been
      a member of an affiliated group (or similar state, local or foreign filing
      group) filing a consolidated income Tax Return (other than a group

                                      -23-


      the common parent of which is Fisher) or (B) has any liability for the
      Taxes of any Person (other than Fisher or any of its Subsidiaries) under
      Treasury Regulation ss. 1.1502-6 (or any similar provision of state, local
      or foreign law), as a transferee or successor, by contract or otherwise.

                   (viii) Neither Fisher nor any of its Subsidiaries has (A)

      Section 481(a) of the Code by reason of a change in accounting method or
      otherwise; or (B) constituted either a "distributing corporation" or a
      "controlled corporation" (within the meaning of Section 355(a)(1)(A) of
      the Code) in a distribution of stock qualifying for tax-free treatment
      under Section 355 of the Code (I) in the two years prior to the date of
      this Agreement or (II) in a distribution which could otherwise constitute
      part of a "plan" or "series of related transactions" (within the meaning
      of Section 355(e) of the Code) in connection with the Merger.

                   (ix) Fisher is not, and has not been, a United States real
      property holding corporation (as defined in Section 897(c)(2) of the Code)
      during the applicable period specified in Section 897(c)(1)(A)(ii) of the
      Code.

                   (x) No closing agreements, private letter rulings, technical
      advice memoranda or similar agreement or ruling have been entered into or
      issued by any Tax Authority with respect to Fisher or any of its
      Subsidiaries within five years of the date of this Agreement, and no such
      agreement or ruling has been applied for and is currently pending.

                   (xi) "Taxes" means any and all federal, state, local, foreign
      or other taxes of any kind (together with any and all interest, penalties,
      additions to tax and additional amounts imposed with respect thereto)
      imposed by any Governmental Entity, including, without limitation, taxes

               (k) Interested Party Transactions. Since the date of the Fisher

Certain Relationship or Related Transaction pursuant to Statement of Financial
Accounting Standards No. 57 or Item 404 of Regulation S-K of the SEC.

               (n) FDA Compliance. All products currently being manufactured,
tested, developed, processed, labeled, stored or distributed by or on behalf of
Fisher and its Subsidiaries, which are subject to the jurisdiction of the FDA,
are being manufactured, tested, developed, processed, labeled, stored,
distributed, and marketed and promoted, including promotions on Fisher's
website, in compliance with all Applicable Laws or regulations issued by the FDA
or any other Governmental Entity, including without limitation, the FDA's
current Good Manufacturing Practice (including, but not limited to, compliance
with corrective and preventive action requirements) and Medical Device Reporting
regulations, and recalls and corrective actions that are required to be reported
to the FDA pursuant to 21 C.F.R. Part 806 have been reported, except where any
failure to so comply would not, individually or in the aggregate, have a
Material Adverse Effect on Fisher and its Subsidiaries, taken as a whole. All

                                      -26-


applicable operations of Fisher and each of its Subsidiaries have achieved and
maintained ISO 13485 Quality System certification, and there is no pending or,
to Fisher's Knowledge, threatened, audit, repeal, failure to renew or challenge
to any such certifications, other than where the failure to achieve or maintain
such certification or any such audit, repeal, failure to renew or challenge
would not, individually or in the aggregate, have a Material Adverse Effect on
Fisher and its Subsidiaries, taken as a whole. All products being manufactured
by Fisher and its Subsidiaries are in compliance with applicable registration
and listing requirements required by Applicable Law for each site at which a
product of Fisher or any of its Subsidiaries is manufactured except where any
failure to so comply would not, individually or in the aggregate, have a
Material Adverse Effect on Fisher and its Subsidiaries, taken as a whole. All
pre-clinical and clinical trials being conducted by or on behalf of Fisher or
any of its Subsidiaries or that were conducted on its behalf to support FDA
approvals or clearances are being or were conducted in compliance with all
Applicable Laws of the FDA or any other Governmental Entity, including without
limitation, the applicable FDA regulations and federal and state laws, and
regulations restricting the use and disclosure of individually identifiable
health information except where any failure to so comply would not, individually
or in the aggregate, have a Material Adverse Effect on Fisher and its
Subsidiaries, taken as a whole. Neither Fisher nor any of its Subsidiaries is
the subject, officially or otherwise, of any pending or, to Fisher's Knowledge,
threatened in writing investigation by the FDA pursuant to its "Fraud, Untrue
Statements of Material Facts, Bribery, and Illegal Gratuities" Final Policy set
forth in 56 Fed. Reg. 46191 (September 10, 1991) and any amendments thereto. To
Fisher's Knowledge, there is no reasonable basis for the FDA to invoke its
policy with respect to "Fraud, Untrue Statements of Material Facts, Bribery and
Illegal Gratuities" and any amendments thereto with respect to the operations of
Fisher or any its Subsidiaries that would result in any material violation of
such policies. To Fisher's Knowledge, each product distributed, sold or leased,
or service rendered, by Fisher or any of its Subsidiaries complies with all
applicable product safety standards of each applicable product safety agency,
commission, board or other Governmental Entity, other than where the failure to
be in compliance would not, individually or in the aggregate, have a Material
Adverse Effect on Fisher and its Subsidiaries, taken as a whole. Fisher and its
Subsidiaries are in compliance with all applicable FDA import and export
requirements, including, but not limited to, import-for-export requirements,
export notifications or authorizations and record keeping requirements except as
would not have, individually or in the aggregate, a Material Adverse Effect on
Fisher and its Subsidiaries, taken as a whole. All devices distributed by Fisher
and its Subsidiaries have obtained any clearances or approvals required by the
FDA to market these devices, including any modifications to the devices or their
labeling, except as would not have, individually or in the aggregate, a Material
Adverse Effect on Fisher and its Subsidiaries, taken as a whole.

               (o) State Takeover Statutes. Fisher has, or will have prior to
the Effective Time, taken all necessary action so that, assuming compliance by
Thermo Electron and Merger Sub with their respective obligations hereunder and
the accuracy of the representations and warranties made by Thermo Electron and
Merger Sub herein, no "business combination," "moratorium," "fair price,"
"control share acquisition" or other state antitakeover statute or regulation
nor any takeover-related provision in the Fisher Organizational Documents, would
(i) prohibit or restrict Fisher's ability to perform its obligations under this
Agreement, any related agreement or the Certificate of Merger or its ability to
consummate the transactions contemplated hereby and thereby, (ii) have the
effect of invalidating or voiding this Agreement

                                      -27-


or the Certificate of Merger, or any provision hereof or thereof, or (iii)
subject Thermo Electron to any impediment or condition in connection with the
exercise of any of its rights under this Agreement or the Certificate of Merger.

               (p) Brokers. Except for fees payable to Goldman, Sachs & Co
("Goldman") and Lazard Freres & Co. LLC ("Lazard"), no broker, investment
banker, financial advisor or other Person is entitled to any broker's, finder's,
financial advisor's or other similar fee or commission in connection with the
transactions contemplated by this Agreement based upon arrangements made by or
on behalf of Fisher. Fisher has previously delivered to Thermo Electron a true
and complete copy of the engagement letters between each of Goldman and Lazard
and Fisher.

               (q) Opinion of Financial Advisor. Fisher has received the opinion
of each of Goldman and Lazard, dated the date of this Agreement, to the effect
that, as of such date, the Exchange Ratio is fair, from a financial point of
view, to the holders of Fisher Common Stock.

               (r) Material Contracts.

                   (i) For purposes of this Agreement, "Fisher Material
      Contract" shall mean:

                       (A) Any employment, severance or consulting Contract or
            offer letter with an employee or former employee, officer or
            director of Fisher or any Subsidiary of Fisher (other than any
            unwritten Contract for the employment of any such employee or former
            employee implied at law) which will require the payment of amounts
            by Fisher or any Subsidiary of Fisher, as applicable, after the date
            hereof in excess of $750,000 per annum;

            may be, would not reasonably be expected to exceed a maximum of
            $5,000,000 (except for product warranty obligations in Contracts for
            the sale of goods in the ordinary course of business) or (2) not to

            Fisher without penalty on 90 days' notice or less) under which
            Fisher or any Subsidiary of Fisher is a purchaser or supplier of

                                      -29-


                       (M) Any Contract entered into on or after January 1, 2003
            relating to the acquisition or disposition of any business or any

            an amount in excess of $100,000,000 (all of which Contracts have
            been made available to Thermo Electron prior to the date hereof);

                       (N) Any Contract (other than Contracts of the type
            described in subclauses (A) through (M) above) that involves
            aggregate payments by or to Fisher or any Subsidiary of Fisher in
            excess of $25,000,000 per annum; and

                       (O) Any Contract the termination or breach of which, or
            the failure to obtain consent in respect of which, would reasonably
            be expected to have a Material Adverse Effect on Fisher and its
            Subsidiaries, taken as a whole.

                   (ii) Schedule. Section 3.1(r)(ii) of the Fisher Disclosure
      Schedule sets forth a list of all Fisher Material Contracts as of the date
      hereof other than those listed as an exhibit to Fisher's most recent Form
      10-K.

                   (iii) No Breach. All Fisher Material Contracts are valid and
      in full force and effect and enforceable in accordance with their
      respective terms, subject to applicable bankruptcy, insolvency,
      reorganization, moratorium or other laws relating to or affecting the
      rights and remedies of creditors generally and to general principles of
      equity (regardless of whether considered in a proceeding in equity or at
      law), except to the extent that (A) they have previously expired in
      accordance with their terms or (B) the failure to be in full force and
      effect, individually or in the aggregate, would not reasonably be expected
      to have a Material Adverse Effect on Fisher and its Subsidiaries, taken as
      a whole. Neither Fisher nor any of its Subsidiaries, nor, to Fisher's
      Knowledge, any counterparty to any Fisher Material Contract, has violated
      any provision of, or committed or failed to perform any act which, with or
      without notice, lapse of time or both, would constitute a default under
      the provisions of any Fisher Material Contract, except in each case for
      those violations and defaults which, individually or in the aggregate,
      would not reasonably be expected to have a Material Adverse Effect on
      Fisher and its Subsidiaries, taken as a whole.

               (s) Real Property. Section 3.1(s) of the Fisher Disclosure
Schedule lists all material real property owned in fee by Fisher or any of its
Subsidiaries (the "Fisher Owned Real Property") or leased by Fisher or any of
its Subsidiaries as lessee (the "Fisher Leased Real Property"). Fisher or any of
its Subsidiaries owns good and valid title to the Fisher Owned Real Property and
has valid and enforceable leasehold interests under the leases with respect to
the Fisher Leased Real Property, free and clear of all Liens other than (i)
Permitted Liens (as defined in Section 8.3(k) and (ii) easements, covenants,
rights-of-way and other encumbrances or restrictions, whether recorded or
referred to in an applicable lease or unrecorded, which do not materially impair
the continued use of the property subject thereto as currently used, but in no
event, with respect to clauses (i) and (ii), environmental or Tax Liens,
judgments, lis pendens or any Lien that would render the title to the Fisher
Owned Real Property uninsurable by a reputable title insurance company. All of
the improvements located on any

                                      -30-


Fisher Owned Real Property or Fisher Leased Real Property are in good condition
and repair (subject to normal wear and tear) without any structural defects of
any kind. Except as set forth in Section 3.1(s) of the Fisher Disclosure
Schedule, each material lease with respect to the Fisher Leased Real Property is
valid, unmodified and in full force and effect, and there are no material
subleases with respect to the Fisher Leased Real Property. Neither any landlord
nor Fisher nor any of its Subsidiaries party to any material lease with respect
to the Fisher Leased Real Property is in monetary or other material default
under any such lease.

               (t) Reorganization. As of the date of this Agreement, neither
Fisher nor any of its Subsidiaries (a) has taken (or caused to be taken) any
action or knows of any fact, agreement, plan or other circumstance that would
reasonably be expected to prevent the Merger from qualifying as a
"reorganization" within the meaning of Section 368(a) of the Code or (b) knows
of any reason why all approvals required for the consummation of the
transactions contemplated by this Agreement should not be obtained on a timely
basis.

         SECTION 3.2. Representations and Warranties of Thermo Electron and
Merger Sub . Except as set forth in the disclosure schedule dated as of the date
of this Agreement and executed and delivered by Thermo Electron and Merger Sub
to Fisher concurrently with or prior to the execution and delivery by Thermo
Electron and Merger Sub of this Agreement (the "Thermo Electron Disclosure
Schedule"), Thermo Electron and Merger Sub represent and warrant to Fisher as
set forth in this Section 3.2. Each disclosure set forth in the Thermo Electron
Disclosure Schedule, and any other information included in the Thermo Electron
Disclosure Schedule, is identified by reference to, or has been grouped under a
heading referring to, a specific individual subsection of this Agreement and
shall be deemed to be disclosed solely for purposes of, and shall qualify and be
treated as an exception to, such subsection, except to the extent that
disclosure in one subsection of the Thermo Electron Disclosure Schedule is
specifically referred to in another subsection of the Thermo Electron Disclosure
Schedule by appropriate cross-reference and except to the extent that the
relevance of a disclosure in one subsection of the Thermo Electron Disclosure
Schedule to another subsection of the Thermo Electron Disclosure Schedule is
reasonably apparent. The parties hereby agree that no reference to or disclosure
of any item or other matter in the Thermo Electron Disclosure Schedule shall be
construed as an admission or indication that (1) such item or other matter is
material, (2) such item or other matter is required to be referred to or
disclosed in the Thermo Electron Disclosure Schedule or (3) any breach or
violation of Applicable Laws or any Contract exists or has actually occurred.

               (a) Organization, Standing and Corporate Power; Charter
Documents; Subsidiaries.

                   (i) Organization, Standing and Corporate Power. Thermo
      Electron and each of its Subsidiaries is a corporation or other legal
      entity duly organized, validly existing and in good standing (with respect
      to jurisdictions which recognize such concept) under the laws of the
      jurisdiction in which it is incorporated or otherwise organized and has
      the requisite corporate (or similar) power and authority and all necessary
      government approvals to own, lease and operate its properties and to carry
      on its business as currently conducted, except for those jurisdictions in
      which the failure to have such power, authority or government approvals
      and to be so organized, existing or

                                      -31-


      in good standing would not, individually or in the aggregate, reasonably
      be expected to have a Material Adverse Effect (as defined in Section
      8.3(i)) on Thermo Electron and its Subsidiaries, taken as a whole. Each of
      Thermo Electron and each of its Subsidiaries is duly qualified or licensed
      to do business and is in good standing (with respect to jurisdictions
      which recognize such concept) in each jurisdiction in which the nature or
      conduct of its business or the ownership, leasing or operation of its
      properties makes such qualification, licensing or good standing necessary,
      except for those jurisdictions where the failure to be so qualified or
      licensed or to be in good standing would not, individually or in the
      aggregate, reasonably be expected to have a Material Adverse Effect on
      Thermo Electron and its Subsidiaries, taken as a whole.

                   (ii) Charter Documents. Thermo Electron and Merger Sub have
      delivered or made available to Fisher prior to the execution of this
      Agreement complete and correct copies of (A) the Amended and Restated
      Certificate of Incorporation of Thermo Electron (including all
      certificates of designation), as amended and currently in effect (the
      "Thermo Electron Charter"), and the By-Laws of Thermo Electron, as amended
      and currently in effect (the "Thermo Electron By-Laws," and, together with
      the Thermo Electron Charter, the "Thermo Electron Organizational
      Documents") and (B) the articles of incorporation and By-Laws of Merger
      Sub and articles or certificate of incorporation and By-Laws or like
      organizational documents of each of the Thermo Electron Material
      Subsidiaries (as defined in Section 3.2(a)(iii)), as amended and currently
      in effect (collectively, the "Thermo Electron Subsidiary Organizational
      Documents"), and each such instrument is in full force and effect. Thermo
      Electron is not in material violation of the Thermo Electron
      Organizational Documents and no Thermo Electron Material Subsidiary is in
      material violation of its Thermo Electron Subsidiary Organizational
      Documents.

                   (iii) Subsidiaries. Section 3.2(a)(iii) of the Thermo
      Electron Disclosure Schedule lists all the Subsidiaries of Thermo Electron
      which, as of the date of this Agreement, have annual gross revenues in
      excess of $200,000,000 (the "Thermo Electron Material Subsidiaries").

      Disclosure Schedule, all the outstanding shares of capital stock of, or
      other equity interests in, each Thermo Electron Material Subsidiary have
      been validly issued and are fully paid and nonassessable and are owned
      directly or indirectly by Thermo Electron, free and clear of all Liens and
      free of any other restriction (including preemptive rights and any

      Subsidiaries, or obligating Thermo Electron or any of its Subsidiaries to

      number of other options, restricted stock awards, warrants or other rights
      to purchase Thermo Electron capital stock.

                   (vi) Neither Thermo Electron nor any of its Subsidiaries is a

      and Merger Sub of the transactions contemplated hereby, have been duly and
      validly authorized by all necessary corporate action on the part of Thermo
      Electron and Merger Sub, and no other corporate proceedings on the part of
      Thermo Electron and Merger Sub and no stockholder votes are necessary to
      authorize this Agreement or to consummate the transactions contemplated
      hereby, other than, with respect to the issuance of shares of Thermo
      Electron Common Stock (as defined in Section 2.1) in connection with the
      Merger (the "Stock Issuance"), and the amendment of the Thermo Electron
      Charter (as defined in Section 3.2(a)(ii)), to increase the authorized
      number of shares of Thermo Electron Common Stock from 350,000,000 to 1.2

      has been duly executed and delivered by Thermo Electron and Merger Sub.
      Assuming the due authorization, execution and delivery of this Agreement
      by Fisher, this Agreement constitutes the legal, valid and binding
      obligation of each of Thermo Electron and Merger Sub, enforceable against
      Thermo Electron and Merger Sub in accordance with its terms, subject to
      applicable bankruptcy, insolvency, reorganization, moratorium or other
      laws relating to or affecting the rights and remedies of creditors
      generally and to general principles of equity (regardless of whether
      considered in a proceeding in equity or at law).

      consummation by Thermo Electron and Merger Sub of the transactions
      contemplated hereby and compliance by Thermo Electron and Merger Sub with
      the provisions of this Agreement will not, conflict with, result in any

                       (G) the filing of the Charter Amendment with the

               (d) SEC Documents; Financial Statements.

                   (i) Thermo Electron has filed with the SEC all registration
      statements, prospectuses, reports, schedules, forms, statements,
      certifications and other documents (including exhibits and all other
      information incorporated by reference therein) presently required to be so
      filed by Thermo Electron since January 1, 2004 (excluding the Form S-4 and
      the Joint Proxy Statement, the "Thermo Electron SEC Documents"). As of
      their respective dates, the Thermo Electron SEC Documents complied in all
      material respects with the requirements of the Securities Act or the
      Exchange Act, as the case may be, to the extent in effect, SOX and the
      rules and regulations of the SEC promulgated thereunder applicable to such
      Thermo Electron SEC Documents, and none of the Thermo Electron SEC
      Documents, when filed, contained any untrue statement of a material fact
      or omitted to state a material fact required to be stated therein or
      necessary in order to make the statements therein, in light of the
      circumstances under which they were made, not misleading, except to the
      extent corrected by a subsequently filed Thermo Electron SEC Document
      filed with the SEC prior to the date hereof. No Subsidiary of Thermo
      Electron is subject to the periodic reporting requirements of the Exchange
      Act.

                   (ii) Each of the principal executive officer of Thermo
      Electron and the principal financial officer of Thermo Electron (or each
      former principal executive

                                      -37-


      officer of Thermo Electron and each former principal financial officer of
      Thermo Electron, as applicable) has made all certifications required by
      Rule 13a-14 or 15d-14 under the Exchange Act or Sections 302 and 906 of
      SOX and the rules and regulations of the SEC promulgated thereunder with
      respect to the Thermo Electron SEC Documents. For purposes of the
      preceding sentence, "principal executive officer" and "principal financial
      officer" shall have the meanings given to such terms in SOX. Neither
      Thermo Electron nor any of its Subsidiaries has outstanding, or has
      arranged any outstanding, "extensions of credit" to directors or executive
      officers within the meaning of Section 402 of SOX.

                   (iii) The financial statements of Thermo Electron included in
      the Thermo Electron SEC Documents, including each Thermo Electron SEC
      Document filed after the date hereof until the Effective Time, comply, as
      of their respective dates of filing with the SEC, in all material respects
      with applicable accounting requirements and the published rules and
      regulations of the SEC with respect thereto, have been prepared in
      accordance with GAAP (except, in the case of unaudited statements, as
      permitted by Form 10-Q or 8-K or other applicable rules of the SEC)
      applied on a consistent basis during the periods involved (except as may
      be indicated in the notes thereto) and fairly present the consolidated
      financial position of Thermo Electron and its consolidated Subsidiaries as
      of the dates thereof and the consolidated results of their operations and
      cash flows for the periods then ended (subject, in the case of unaudited
      statements, to normal year-end audit adjustments which are not material).
      The financial books and records of Thermo Electron and its Subsidiaries,
      taken as a whole, are true and correct in all material respects.

                   (iv) Except as reflected or reserved against in the balance
      sheet of Thermo Electron, dated December 31, 2005, included in the Form
      10-K filed by Thermo Electron with the SEC on March 2, 2006 (including the
      notes thereto, the "Thermo Electron Balance Sheet") and except as set
      forth in Section 3.2(d)(iv) of the Thermo Electron Disclosure Schedule,
      neither Thermo Electron nor any of its Subsidiaries has any liabilities or
      obligations of any nature (whether absolute, accrued, known or unknown,
      contingent or otherwise) nor, to the Knowledge (as defined in Section
      8.3(h)) of Thermo Electron, does any basis exist therefor, other than
      liabilities or obligations that (A) were incurred since January 1, 2006 in
      the ordinary course of business consistent with past practice and
      individually or in the aggregate, have not had and would not reasonably be
      expected to have a Material Adverse Effect on Thermo Electron and its
      Subsidiaries, taken as a whole, (B) individually or in the aggregate, have
      not had and would not reasonably be expected to have a Material Adverse
      Effect on Thermo Electron and its Subsidiaries, taken as a whole or (C)
      were incurred pursuant to this Agreement or the transactions contemplated
      hereby.

                   (v) Neither Thermo Electron nor any of its Subsidiaries is a
      party to, or has any commitment to become a party to, any joint venture,
      off-balance sheet partnership or any similar contract or arrangement
      (including without limitation any contract or arrangement relating to any
      transaction or relationship between or among Thermo Electron and any of
      its Subsidiaries, on the one hand, and any unconsolidated Affiliate,
      including without limitation any structured finance, special purpose or
      limited

                                      -38-


      purpose entity or Person, on the other hand, or any "off-balance sheet
      arrangement" (as defined in Item 303(a) of Regulation S-K of the SEC)),
      where the result, purpose or intended effect of such contract or
      arrangement is to avoid disclosure of any material transaction involving,
      or material liabilities of, Thermo Electron or any of its Subsidiaries in
      Thermo Electron's or such Subsidiary's published financial statements or
      other Thermo Electron SEC Documents.

                   (vi) No "material contract" (as such term is defined in Item
      601(b)(10) of Regulation S-K of the SEC) filed as an exhibit to the Thermo
      Electron Form 10-K has been amended or modified, except for amendments or
      modifications which have been filed as an exhibit to a subsequently dated
      Thermo Electron SEC Document or are not required to be filed with the SEC.

               (e) Information Supplied. None of the information supplied or to
be supplied by or on behalf of Thermo Electron or Merger Sub for inclusion or
incorporation by reference in (i) the Form S-4 will, at the time the Form S-4
becomes effective under the Securities Act, contain any untrue statement of a
material fact or omit to state any material fact required to be stated therein
or necessary to make the statements therein not misleading or (ii) the Joint
Proxy Statement will, at the date it is first mailed to Thermo Electron's
stockholders or at the time of the Thermo Electron Stockholders' Meeting,
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 Joint Proxy Statement and the Form S-4 will comply as to form in
all material respects with the requirements of the Securities Act and the
Exchange Act and the rules and regulations thereunder. Notwithstanding the
foregoing provisions of this Section 3.2(e), no representation or warranty is
made by Thermo Electron with respect to information or statements made or
incorporated by reference in the Form S-4 or the Joint Proxy Statement which
were not supplied by or on behalf of Thermo Electron.

               (f) Absence of Certain Changes or Events.

                   (i) Since January 1, 2006 through the date hereof, except as
      and to the extent disclosed in the Thermo Electron SEC Documents filed
      prior to the date of this Agreement and except for liabilities incurred
      pursuant to this Agreement or the transactions contemplated hereby:

                       (A) Thermo Electron and its Subsidiaries have conducted
            their business only in the ordinary course consistent with past
            practice;

                       (B) there has not been any split, combination or
            reclassification of any of Thermo Electron's capital stock or any
            declaration, setting aside or payment of any dividend on, or other
            distribution (whether in cash, stock or property) in respect of, in
            lieu of or in substitution for, shares of Thermo Electron's capital
            stock;

                                      -39-


                       (C) except as required by a change in GAAP, there has not
            been any change in accounting methods, principles or practices by
            Thermo Electron; and

                       (D) there has not been any action taken by Thermo
            Electron or any of its Subsidiaries that, if taken during the period
            from the date of this Agreement through the Effective Time, would
            constitute a breach of Section 4.1(a), other than actions in
            connection with entering into this Agreement.

                   (ii) Since January 1, 2006 through the date hereof, there
      have not been any changes, circumstances or events that, individually or
      in the aggregate, have had, or would reasonably be expected to have, a
      Material Adverse Effect on Thermo Electron and its Subsidiaries, taken as
      a whole, or Merger Sub.

                   (i) Thermo Electron, its Subsidiaries and employees hold all
      authorizations, permits, licenses, certificates, easements, concessions,
      franchises, variances, exemptions, orders, consents, registrations,
      approvals and clearances of all Governmental Entities (including all
      authorizations under the FDCA, and the regulations of the FDA promulgated
      thereunder) and third Persons which are required for Thermo Electron and
      its Subsidiaries to own, lease and operate its properties and other assets
      and to carry on their respective businesses in the manner described in the
      Thermo Electron SEC Documents filed prior to the date hereof and as they
      are being conducted as of the date hereof (the "Thermo Electron Permits"),
      and all Thermo Electron Permits are valid and in full force and effect,
      except where the failure to have, or the suspension or cancellation of, or
      the failure to be valid or in full force and effect of, any such Thermo
      Electron Permits, individually or in the aggregate, would not reasonably
      be expected to have a Material Adverse Effect on Thermo Electron and its
      Subsidiaries, taken as a whole.

                   (ii) Thermo Electron and its Subsidiaries are, and have been
      at all times since January 1, 2004, in compliance with the terms of the
      Thermo Electron Permits and all Applicable Laws relating to Thermo
      Electron and its Subsidiaries or their respective businesses, assets or
      properties, except where the failure to be in compliance with the terms of
      the Thermo Electron Permits or such Applicable Laws, individually or in
      the aggregate, would not reasonably be expected to have a Material Adverse

      a Material Adverse Effect on Thermo Electron and its Subsidiaries, taken
      as a whole) or (B) threatening to revoke any Thermo Electron Permit
      (except for any such revocation which, individually or in the aggregate,
      would not reasonably be expected to have a Material Adverse Effect on
      Thermo Electron and its Subsidiaries, taken as a whole) nor, to the
      Knowledge of Thermo

                                      -40-


      Electron, does any basis exist therefor. As of the date hereof, no
      investigation or review by any Governmental Entity is pending or, to the
      Knowledge of Thermo Electron, has been threatened in writing against
      Thermo Electron or any of its Subsidiaries, which, individually or in the
      aggregate, would reasonably be expected to have a Material Adverse Effect
      on Thermo Electron and its Subsidiaries, taken as a whole.

                   (iii) Thermo Electron is, and has been, in compliance in all
      material respects with the provisions of SOX applicable to it.

      Electron, threatened which, individually or in the aggregate, would
      reasonably be expected to have a Material Adverse Effect on Thermo
      Electron and its Subsidiaries, taken as a whole, or Merger Sub.

                   (v) Neither Thermo Electron nor any of its Subsidiaries is,
      or at any time since January 1, 2004 has been, subject to any outstanding
      order, injunction or decree which, individually or in the aggregate, has

      of its Subsidiaries or to the use of trade secrets or proprietary
      information of others,(G) neither Thermo Electron nor any of its

            of any non-U.S. agreement, work rules or practices with a labor
            union, labor organization or works council are material to Thermo
            Electron and its Subsidiaries, taken as a whole, nor are any such

      that has been adopted or maintained by Thermo Electron, any of its
      Subsidiaries or any Affiliate, whether formally or informally, or with
      respect to which Thermo Electron, any of its Subsidiaries or any Affiliate
      will or may have any material liability, for the benefit of employees or
      consultants of Thermo Electron or any of its Subsidiaries who perform
      services outside the United States (collectively, the "Thermo Electron
      Benefit Plans"). With respect to the Thermo Electron Benefit Plans, no
      event has occurred, and there exists no condition or set of circumstances,
      which would reasonably be expected to have a Material Adverse Effect on
      Thermo Electron and its Subsidiaries, taken as a whole, under ERISA, the
      Code or any other Applicable Laws. Neither Thermo Electron, nor any of its
      Subsidiaries, nor, to the Knowledge of Thermo Electron, any other Person,
      has any express commitment, whether legally enforceable or not, to modify,
      change or terminate any Thermo Electron Benefit Plan, other than with
      respect to a modification, change or termination required by ERISA or the
      Code, or any other Applicable Law or administrative changes that do not
      increase the liabilities or obligations under any such plans. Thermo
      Electron has delivered or made available to Fisher true, correct and
      complete copies of all Thermo Electron Benefit Plans and, with respect
      thereto, if applicable, all amendments, trust agreements, insurance
      contracts, other funding vehicles, determination letters issued by the
      IRS, the most recent annual reports (Form 5500 series) filed with the IRS
      and the most recent actuarial report or other financial statement relating
      to such Thermo Electron Benefit Plan.

                   (ii) Each Thermo Electron Benefit Plan has been, in all
      material respects, administered and operated in accordance with its terms,
      with the applicable provisions of ERISA, the Code and other Applicable
      Laws and with the terms of all applicable collective bargaining
      agreements. Each Thermo Electron Benefit Plan, including any material
      amendments thereto, that is required to obtain Approval has received such
      Approval (or there remains a period of time in which to obtain such
      Approval retroactive to the date of any material amendment that has not
      previously received such Approval), and no event has occurred which would
      reasonably be expected to result in the revocation of such Approval or the
      imposition of material sanctions by such authorities. Without limiting the
      generality of the foregoing, each Thermo Electron Benefit Plan that is
      intended to be qualified under Section 401(a) of the Code has obtained a
      favorable determination letter from the IRS that the Thermo Electron
      Benefit Plan is so qualified and all related trusts are exempt from U.S.
      federal income taxation under Section 501(a) of the Code, and, to the
      Knowledge of Thermo Electron, nothing has occurred, whether by action or
      by failure to act, which would reasonably be expected to cause the loss of
      such qualification or exemption.

                   (iii) As of the date hereof to the Knowledge of Thermo
      Electron, no oral or written representation or commitment with respect to
      any material aspect of any Thermo Electron Benefit Plan has been made to
      an employee or former employee of Thermo Electron or any of its
      Subsidiaries by an authorized Thermo Electron employee that is not
      materially in accordance with the written or otherwise pre-existing terms
      and provisions of such Thermo Electron Benefit Plans. As of the date
      hereof, to the Knowledge of Thermo Electron, neither Thermo Electron nor
      any of its

                                      -43-


      Subsidiaries has entered into any agreement, arrangement or understanding,
      whether written or oral, with any trade union, works council or other
      employee representative body or any material number or category of its
      employees which would prevent, restrict or materially impede the
      implementation of any layoff, redundancy, severance or similar program
      within its or their respective workforces (or any part of them).

                   (iv) There are no material unresolved claims or disputes
      under the terms of, or in connection with, any Thermo Electron Benefit
      Plan (other than routine undisputed claims for benefits), and no action,
      legal or otherwise, has been commenced or threatened with respect to any
      material claim or otherwise in connection with a Thermo Electron Benefit
      Plan.

                   (v) With respect to each Funded Retirement Plan of Thermo
      Electron or any of its Subsidiaries, the aggregate fair market value of
      the assets of such Funded Retirement Plan was, as of the most recently
      computed actuarial valuation of such plan, equal to or greater than the
      aggregate value of its liabilities assessed on an ongoing basis and
      calculated in accordance with the actuarial methods and assumptions used
      in such valuation pursuant to such Funded Retirement Plan and Applicable
      Law and GAAP. None of Thermo Electron or any ERISA Affiliate of Thermo
      Electron has incurred, or is reasonably expected to incur, any liability
      to a Funded Retirement Plan under Title IV of ERISA (other than for
      contributions not yet due) or to the Pension Benefit Guaranty Corporation
      (other than for payment of premiums not yet due) that, when aggregated
      with other such liabilities, would reasonably be expected to result in a
      material liability of Thermo Electron and its Subsidiaries, taken as a
      whole, which liability has not been fully paid.

                   (vi) Section 3.1(i)(vi) of the Thermo Electron Disclosure
      Schedule sets forth a true and complete list of each Multiemployer Plan to
      which Thermo Electron or any ERISA Affiliate of Thermo Electron
      contributes or is required to contribute, or to which, or with respect to
      which, Thermo Electron or any ERISA Affiliate of Thermo Electron has any
      material liability. If any Thermo Electron Multiemployer Plan is subject
      to Title IV of ERISA, then, (A) neither Thermo Electron nor any ERISA
      Affiliate of Thermo Electron has made or suffered a "complete withdrawal"
      or a "partial withdrawal," as such terms are respectively defined in
      Sections 4203 and 4205 of ERISA (or any liability resulting therefrom has
      been satisfied in full), (B) no event has occurred that presents a
      material risk of a complete or partial withdrawal, (C) neither Thermo
      Electron nor any ERISA Affiliate of Thermo Electron has any contingent
      liability under Section 4204 of ERISA, (D) no circumstances exist that
      present a material risk that any such plan will go into reorganization,
      and (E) to the best of Thermo Electron's Knowledge, the aggregate
      withdrawal liability of Thermo Electron and each ERISA Affiliate of Thermo
      Electron computed as if a complete withdrawal by Thermo Electron and any
      ERISA Affiliate of Thermo Electron had occurred under each such Thermo
      Electron Benefit Plan on the date hereof, would not reasonably be expected
      to result in a material liability to Thermo Electron. No Thermo Electron
      Benefit Plan subject to ERISA is a plan that has two or more contributing
      sponsors at least two of whom are not under common control, within the
      meaning of Section 4063 of ERISA.

                                      -44-


                   (vii) No Thermo Electron Benefit Plan provides health
      benefits (whether or not insured) with respect to employees or former
      employees of Thermo Electron or any of its Subsidiaries after retirement
      or other termination of service (other than coverage mandated by
      Applicable Laws or benefits, the full cost of which is borne by the
      employee or former employee).

                   (viii) Neither the negotiation and execution of this
      Agreement nor the consummation of the transactions contemplated hereby
      will (either alone or upon the occurrence of any additional or subsequent
      events) constitute an event under any Thermo Electron Benefit Plan (for
      this purpose, Thermo Electron Benefit Plan (other than with respect to
      those Plans that are Thermo Electron Foreign Plans) shall be determined
      without regard to whether any plan, agreement, policy, understanding or
      arrangement is material despite the use of such qualifier in Section
      3.1(i)(i) for purposes of the definition of Benefit Plan and Section
      3.2(i)(i) for purposes of the definition of Thermo Electron Benefit Plan)
      that will or may result in any payment (whether of severance pay or
      otherwise), acceleration of payment, forgiveness of indebtedness, vesting,
      distribution, increase in benefits or obligation to fund benefits with
      respect to any employee or former employee of Thermo Electron or any of
      its Subsidiaries or limit the ability to amend, terminate or receive a
      reversion of assets from any Thermo Electron Benefit Plan or related
      trust. There is no contract, agreement, plan or arrangement with an
      employee or former employee of Thermo Electron to which Thermo Electron or
      any of its Subsidiaries is a party as of the date of this Agreement that,
      individually or collectively and as a result of the transaction
      contemplated hereby (whether alone or upon the occurrence of any
      additional or subsequent events) would reasonably be expected to give rise
      to the payment of any amount that would not be deductible pursuant to
      Sections 280G or 162(m) of the Code.

                   (ix) Except as would not, individually or in the aggregate,
      reasonably be expected to have a Material Adverse Effect on Thermo
      Electron and its Subsidiaries, taken as a whole, with respect to each
      Thermo Electron Benefit Plan established or maintained outside of the
      United States for the benefit of employees of Thermo Electron or any
      Subsidiary of Thermo Electron residing outside the United States (each, a
      "Thermo Electron Foreign Plan"): (i) each Thermo Electron Foreign Plan is
      in compliance with the applicable provisions of the laws and regulations
      regarding employee benefits, mandatory contributions and retirement plans
      of each jurisdiction applicable to such Thermo Electron Foreign Plan; (ii)
      each Thermo Electron Foreign Plan required to be registered has been
      registered and has been maintained in good standing with applicable
      regulatory authorities and (iii) the fair market value of the assets of
      each funded Thermo Electron Foreign Plan, the liability of each insurer
      for any Thermo Electron Foreign Plan funded through insurance or the book
      reserve established for any Thermo Electron Foreign Plan, together with
      any accrued contributions, is sufficient to procure or provide for the
      accrued benefit obligations, as of the Closing Date, with respect to all
      current and former participants in such plan according to the actuarial
      assumptions and valuations most recently used to determine employer
      contributions to such Thermo Electron Foreign Plan and no transaction
      contemplated by this Agreement shall cause such assets or insurance
      obligations to be less than such benefit obligations, and any and all
      amounts required to be accrued with respect to any Thermo Electron

                                      -45-


      Foreign Plan or pursuant to any statutory requirements pertaining to
      employee benefits, mandatory contributions, retirement plans or similar
      benefits, have been properly and timely accrued, including accruals
      relating to any severance, termination pay or profit sharing benefits.

               (j) Taxes. Except as would not, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect on Thermo Electron and
its Subsidiaries, taken as a whole:

                   (i) Each of Thermo Electron and its Subsidiaries has (A) duly
      and timely filed (or there have been filed on its behalf) all Tax Returns
      required to be filed by it (taking into account all applicable extensions)
      with the appropriate Tax Authority and all such Tax Returns are true,
      correct and complete, (B) timely paid in full all Taxes required to be
      paid by it, (C) made adequate provision in accordance with GAAP (or
      there has been paid or provision has been made on its behalf) for the
      payment of all Taxes not yet due and (D) complied with all Applicable Laws
      relating to the payment and withholding of Taxes.

                   (ii) There are no Liens for Taxes upon any property or assets
      of Thermo Electron or any of its Subsidiaries, except for Liens for Taxes
      not yet due and payable or for which adequate reserves have been provided
      in accordance with GAAP in the most recent financial statements contained
      in the Thermo Electron SEC Documents filed prior to the date of this
      Agreement.

                   (iii) The most recent financial statements contained in the
      Thermo Electron SEC Documents reflect an adequate (A) reserve in
      accordance with GAAP for all Tax liabilities of Thermo Electron and its
      Subsidiaries for all taxable periods and portions thereof accrued through
      the date of such financial statements and (B) valuation allowance in
      accordance with GAAP for all deferred tax assets of Thermo Electron and
      its Subsidiaries for all taxable periods and portions thereof accrued
      through the date of such financial statements.

                   (iv) There is no audit, examination, deficiency, refund
      litigation, proposed adjustment or matter in controversy with respect to
      any Taxes or Tax Return of Thermo Electron or any of its Subsidiaries.
      Neither Thermo Electron nor any of its Subsidiaries has received written
      notice of any claim made by a Governmental Entity in a jurisdiction where
      Thermo Electron or any of its Subsidiaries, as applicable, does not file a
      Tax Return, that Thermo Electron or such Subsidiary is or may be subject
      to taxation by that jurisdiction.

                   (v) The Tax Returns of Thermo Electron and each of its
      Subsidiaries, including any predecessors thereof, have been examined by
      the applicable Tax Authority (or the applicable statutes of limitations
      for the assessment of income Taxes for such periods have expired) for all
      periods through and including December 31, 2000, and no deficiencies were
      asserted as a result of such examinations which have not been resolved and
      fully paid or accrued as a liability on the most recent financial
      statements contained in the Thermo Electron SEC Documents.

                                      -46-


                   (vi) There are no outstanding requests, agreements, consents
      or waivers to extend the statutory period of limitations applicable to the
      assessment of any Taxes or deficiencies against Thermo Electron or any of
      its Subsidiaries, and no power of attorney granted by either Thermo
      Electron or any of its Subsidiaries with respect to any Taxes is currently
      in force.

                   (vii) Neither Thermo Electron nor any of its Subsidiaries is
      a party to any agreement providing for the allocation, indemnification or
      sharing of Taxes (other than any agreements solely between or among Thermo
      Electron and its Subsidiaries), and neither Thermo Electron nor any of its
      Subsidiaries (A) has been a member of an affiliated group (or similar
      state, local or foreign filing group) filing a consolidated income Tax
      Return (other than a group the common parent of which is Thermo Electron)
      or (B) has any liability for the Taxes of any Person (other than Thermo
      Electron or any of its Subsidiaries) under Treasury Regulation ss.
      1.1502-6 (or any similar provision of state, local or foreign law), as a
      transferee or successor, by contract or otherwise.

                   (viii) Neither Thermo Electron nor any of its Subsidiaries
      has (A) agreed to make nor is it required to make any material adjustment
      under Section 481(a) of the Code by reason of a change in accounting
      method or otherwise; or (B) constituted either a "distributing
      corporation" or a "controlled corporation" (within the meaning of Section
      355(a)(1)(A) of the Code) in a distribution of stock qualifying for
      tax-free treatment under Section 355 of the Code (1) in the two years
      prior to the date of this Agreement or (2) in a distribution which could
      otherwise constitute part of a "plan" or "series of related transactions"
      (within the meaning of Section 355(e) of the Code) in connection with the
      Merger.

                   (ix) Thermo Electron is not, and has not been, a United
      States real property holding corporation (as defined in Section 897(c)(2)
      of the Code) during the applicable period specified in Section
      897(c)(1)(A)(ii) of the Code.

                   (x) No closing agreements, private letter rulings, technical
      advice memoranda or similar agreements or rulings have been entered into
      or issued by any Tax Authority with respect to Thermo Electron or any of
      its Subsidiaries within five years of the date of this Agreement, and no
      such agreement or ruling has been applied for and is currently pending.

               (k) Interested Party Transactions. Since the date of the Thermo
Electron Balance Sheet, no event has occurred that would be required to be
reported as a Certain Relationship or Related Transaction pursuant to Statement
of Financial Accounting Standards No. 57 or Item 404 of Regulation S-K of the
SEC.

               (n) FDA Compliance. All products currently being manufactured,
tested, developed, processed, labeled, stored or distributed by or on behalf of
Thermo Electron and its Subsidiaries, which are subject to the jurisdiction of
the FDA, are being manufactured, tested, developed, processed, labeled, stored,
distributed, and marketed and promoted, including promotions on Thermo
Electron's website, in compliance with all Applicable Laws or regulations issued
by the FDA or any other Governmental Entity, including without limitation, the
FDA's current Good Manufacturing Practice (including, but not limited to,
compliance with

                                      -49-


corrective and preventive action requirements) and Medical Device Reporting
regulations, and recalls and corrective actions that are required to be reported
to the FDA pursuant to 21 C.F.R. Part 806 have been reported, except where any
failure to so comply would not, individually or in the aggregate, have a
Material Adverse Effect on Thermo Electron and its Subsidiaries, taken as a
whole. All applicable operations of Thermo Electron and each of its Subsidiaries
have achieved and maintained ISO 13485 Quality System certification, and there
is no pending or, to Thermo Electron's Knowledge, threatened, audit, repeal,
failure to renew or challenge to any such certifications, other than where the
failure to achieve or maintain such certification or any such audit, repeal,
failure to renew or challenge would not, individually or in the aggregate, have
a Material Adverse Effect on Thermo Electron and its Subsidiaries, taken as a
whole. All products being manufactured by Thermo Electron and its Subsidiaries
are in compliance with applicable registration and listing requirements required
by Applicable Law for each site at which a product of Thermo Electron or any of
its Subsidiaries is manufactured except where any failure to so comply would
not, individually or in the aggregate, have a Material Adverse Effect on Thermo
Electron and its Subsidiaries, taken as a whole. All pre-clinical and clinical
trials being conducted by or on behalf of Thermo Electron or any of its
Subsidiaries or that were conducted on its behalf to support FDA approvals or
clearances are being or were conducted in compliance with all Applicable Laws of
the FDA or any other Governmental Entity, including without limitation, the
applicable FDA regulations and federal and state laws, and regulations
restricting the use and disclosure of individually identifiable health
information except where any failure to so comply would not, individually or in
the aggregate, have a Material Adverse Effect on Thermo Electron and its
Subsidiaries, taken as a whole. Neither Thermo Electron nor any of its
Subsidiaries is the subject, officially or otherwise, of any pending or, to
Thermo Electron's Knowledge, threatened in writing investigation by the FDA
pursuant to its "Fraud, Untrue Statements of Material Facts, Bribery, and
Illegal Gratuities" Final Policy set forth in 56 Fed. Reg. 46191 (September 10,
1991) and any amendments thereto. To Thermo Electron's Knowledge, there is no
reasonable basis for the FDA to invoke its policy with respect to "Fraud, Untrue
Statements of Material Facts, Bribery and Illegal Gratuities" and any amendments
thereto with respect to the operations of Thermo Electron or any its
Subsidiaries that would result in any material violation of such policies. To
Thermo Electron's Knowledge, each product distributed, sold or leased, or
service rendered, by Thermo Electron or any of its Subsidiaries complies with
all applicable product safety standards of each applicable product safety
agency, commission, board or other Governmental Entity, other than where the
failure to be in compliance would not, individually or in the aggregate, have a
Material Adverse Effect on Thermo Electron and its Subsidiaries, taken as a
whole. Thermo Electron and its Subsidiaries are in compliance with all
applicable FDA import and export requirements, including, but not limited to,
import-for-export requirements, export notifications or authorizations and
record keeping requirements except as would not have, individually or in the
aggregate, a Material Adverse Effect on Thermo Electron and its Subsidiaries,
taken as a whole. All devices distributed by Thermo Electron and its
Subsidiaries have obtained any clearances or approvals required by the FDA to
market these devices, including any modifications to the devices or their
labeling, except as would not have, individually or in the aggregate, a Material
Adverse Effect on Thermo Electron and its Subsidiaries, taken as a whole.

               (o) State Takeover Statutes. Thermo Electron has, or will have
prior to the Effective Time, taken all necessary action so that, assuming
compliance by Fisher with its obligations hereunder and the accuracy of the
representations and warranties made by Fisher

                                      -50-


herein, no "business combination," "moratorium," "fair price," "control share
acquisition" or other state antitakeover statute or regulation nor any
takeover-related provision in the Thermo Electron Organizational Documents,
would (i) prohibit or restrict Thermo Electron's ability to perform its
obligations under this Agreement, any related agreement or the Certificate of
Merger or its ability to consummate the transactions contemplated hereby and
thereby, (ii) have the effect of invalidating or voiding this Agreement or the
Certificate of Merger, or any provision hereof or thereof, or (iii) subject
Thermo Electron to any impediment or condition in connection with the exercise
of any of its rights under this Agreement or the Certificate of Merger.

               (p) Brokers. Except for fees payable to Lehman Brothers Inc.
("Lehman Brothers") and Rothschild, Inc. ("Rothschild, Inc."), no broker,
investment banker, financial advisor or other Person, is entitled to any
broker's, finder's, financial advisor's or other similar fee or commission in
connection with the transactions contemplated by this Agreement based upon
arrangements made by or on behalf of Thermo Electron or Merger Sub. Thermo
Electron has previously delivered to Fisher a true and complete copy of the
engagement letters between each of Lehman Brothers and Rothschild, Inc. and
Thermo Electron.

               (q) Opinion of Financial Advisor. Thermo Electron has received
the opinion of its financial advisor, Lehman Brothers, dated the date of this

a financial point of view, to the holders of Thermo Electron Common Stock.

            Electron;

                       (I) Any Contract under which Thermo Electron or any
            Subsidiary of Thermo Electron is (1) a lessee of real property, (2)

                       (O) Any Contract the termination or breach of which, or
            the failure to obtain consent in respect of which, would reasonably
            be expected to have a Material Adverse Effect on Thermo Electron and
            its Subsidiaries, taken as a whole.

                   (ii) Schedule. Section 3.2(r)(ii) of the Thermo Electron
      Disclosure Schedule sets forth a list of all Thermo Electron Material
      Contracts as of the date hereof other than those listed as an exhibit to
      Thermo Electron's most recent Form 10-K.

                   (iii) No Breach. All Thermo Electron Material Contracts are
      valid and in full force and effect and enforceable in accordance with
      their respective terms, subject to applicable bankruptcy, insolvency,
      reorganization, moratorium or other laws relating to or affecting the
      rights and remedies of creditors generally and to general principles of
      equity (regardless of whether considered in a proceeding in equity or at
      law), except to the extent that (A) they have previously expired in
      accordance with their terms or (B) the failure to be in full force and
      effect, individually or in the aggregate, would not reasonably be expected
      to have a Material Adverse Effect on Thermo Electron and its Subsidiaries,
      taken as a whole. Neither Thermo Electron nor any of its Subsidiaries,
      nor, to Thermo Electron's Knowledge, any counterparty to any Thermo
      Electron Material Contract, has violated any provision of, or committed or
      failed to perform any act which, with or without notice, lapse of time or
      both would constitute a default under the provisions of, any Thermo
      Electron Material Contract, except in each case for those violations and
      defaults which, individually or in the aggregate, would not reasonably be
      expected to have a Material Adverse Effect on Thermo Electron and its
      Subsidiaries, taken as a whole.

                                      -53-


               (s) Real Property. Section 3.2(s) of the Thermo Electron
Disclosure Schedule lists all material real property owned in fee by Thermo
Electron or any of its Subsidiaries (the "Thermo Electron Owned Real Property")
or leased by Thermo Electron or any of its Subsidiaries as lessee (the "Thermo
Electron Leased Real Property"). Thermo Electron or any of its Subsidiaries owns
good and valid title to the Thermo Electron Owned Real Property and has valid
and enforceable leasehold interests under the leases with respect to the Thermo
Electron Leased Real Property, free and clear of all Liens other than (i)
Permitted Liens and (ii) easements, covenants, rights-of-way and other
encumbrances or restrictions, whether recorded or referred to in an applicable
lease or unrecorded, which do not materially impair the continued use of the
property subject thereto as currently used, but in no event, with respect to
clauses (i) and (ii), environmental or Tax Liens, judgments, lis pendens or any
Lien that would render the title to the Thermo Electron Owned Real Property
uninsurable by a reputable title insurance company. All of the improvements
located on any Thermo Electron Owned Real Property or Thermo Electron Leased
Real Property are in good condition and repair (subject to normal wear and tear)
without any structural defects of any kind. Except as set forth in Section
3.2(s) of the Thermo Electron Disclosure Schedule, each material lease with
respect to the Thermo Electron Leased Real Property is valid, unmodified and in
full force and effect, and there are no material subleases with respect to the
Thermo Electron Leased Real Property. Neither any landlord nor Thermo Electron
nor any of its Subsidiaries party to any material lease with respect to the
Thermo Electron Leased Real Property is in monetary or other material default
under any such lease.

               (t) Reorganization. As of the date of this Agreement, neither
Thermo Electron nor any of its Subsidiaries (a) has taken (or caused to be
taken) any action or knows of any fact, agreement, plan or other circumstance
that would reasonably be expected to prevent the Merger from qualifying as a
"reorganization" within the meaning of Section 368(a) of the Code or (b) knows
of no reason why all approvals required for the consummation of the transactions
contemplated by this Agreement should not be obtained on a timely basis.

               (u) Merger Sub Approval. The Board of Directors of Merger Sub, by
written consent duly adopted prior to the date hereof, (i) determined that this
Agreement and the Merger are advisable and fair to and in the best interests of
Merger Sub and its stockholder, (ii) duly approved and adopted this Agreement,
the Merger and the other transactions contemplated hereby, which adoption has
not been rescinded or modified, and (iii) submitted this Agreement for adoption
by Thermo Electron, as the sole stockholder of Merger Sub. Promptly following
the date hereof, Thermo Electron, as the sole stockholder of Merger Sub, will
have duly approved and adopted this Agreement and the Merger.

               (v) Thermo Electron has resolved to take and has taken all action
necessary to render the terms of the Thermo Electron Rights Agreement (as
defined in Section 4.1(a)(ii)) and the rights thereunder inapplicable to the
execution and operation of this Agreement and the transactions contemplated
hereby.

      severance payments and benefits pursuant to such agreement;

      and its Subsidiaries, taken as a whole, or Thermo Electron and its
      Subsidiaries, taken as a whole, respectively;

                   (xviii) fail to use reasonable best efforts to maintain in
      full force and effect insurance coverage substantially similar to
      insurance coverage maintained on the date hereof;

                   (xix) enter into any non-competition contract or other

      any of them may so engage in any business; or

                   (xx) authorize or enter into any agreement or otherwise make
      any commitment to do any of the foregoing.

         SECTION 4.2. No Solicitation.

               (a) From the date hereof until the earlier of the Effective Time
and the termination of this Agreement, none of Fisher or Thermo Electron, their
respective Subsidiaries or any officer, director, employee, agent or
representative (including any investment banker,

                                      -59-


financial advisor, attorney, accountant or other retained representative)
("Representatives") of Fisher or Thermo Electron or any of their respective
Subsidiaries shall directly or indirectly (i) solicit, initiate or encourage or
knowingly facilitate (including by way of furnishing information or entering
into any agreements, arrangements or understandings) or take any other action
designed to facilitate any inquiries or proposals regarding any merger, share
exchange, consolidation, sale of assets, sale of shares of capital stock
(including, without limitation, by way of a tender offer) or similar
transactions involving Fisher or Thermo Electron or any of their respective
Subsidiaries that, if consummated, would constitute an Alternative Transaction
(as defined in Section 8.3(b)) (any of the foregoing inquiries or proposals
being referred to herein as an "Alternative Transaction Proposal"), (ii)
participate in any discussions or negotiations regarding an Alternative
Transaction or (iii) enter into any agreement regarding any Alternative
Transaction. Notwithstanding the foregoing, the Board of Directors of Fisher and
Thermo Electron, respectively, shall be permitted, prior to the receipt of the
Fisher Stockholder Approval and Thermo Electron Stockholder Approval,
respectively, and subject to compliance with the other terms of this Agreement,
including this Section 4.2, and to first entering into a confidentiality
agreement with the person proposing such Alternative Transaction Proposal on
terms substantially similar to, and no less favorable to Fisher or Thermo
Electron, respectively, than those contained in the Confidentiality Agreement,
dated as of April 13, 2006, as amended as of May 7, 2006, between Fisher and
Thermo Electron (the "CDA"), to (x) furnish information with respect to Fisher
or Thermo Electron and their respective Subsidiaries, as the case may be, to the
Person making such bona fide written Alternative Transaction Proposal (and its
Representatives) and (y) participate in discussions and negotiations with
respect to such bona fide written Alternative Transaction Proposal received by
Fisher or Thermo Electron, as applicable, in each case if the Board of Directors
of Fisher or Thermo Electron, as the case may be, determines in good faith
(after consultation with outside legal counsel) that the failure to do so would,
or would reasonably be likely to, cause it to violate its fiduciary duties.

               (b) From the date hereof until the earlier of the Effective Time
and the termination of this Agreement, Fisher shall notify Thermo Electron and
Thermo Electron shall notify Fisher, as the case may be, promptly (but in no
event later than 24 hours) after receipt of any Alternative Transaction
Proposal, or any material modification of or material amendment to any
Alternative Transaction Proposal or any request for nonpublic information
relating to Fisher or Thermo Electron, respectively, or any of their respective
Subsidiaries relating to any Alternative Transaction Proposal. Such notice to
Fisher or Thermo Electron, as the case may be, shall be made orally and in
writing, and shall indicate the identity of the Person making the Alternative
Transaction Proposal or such request and the material terms of any such
Alternative Transaction Proposal or any material modification or material
amendment to an Alternative Transaction Proposal. From the date hereof until the
earlier of the Effective Time and the termination of this Agreement, Fisher
shall keep Thermo Electron and Thermo Electron shall keep Fisher reasonably
informed on a current basis of any material changes in the status and any
material changes or modifications in the terms of any such Alternative
Transaction Proposal, indication or request. Fisher shall also promptly, and in
any event within 24 hours, notify Thermo Electron, and Thermo Electron shall
also promptly, and in any event within 24 hours, notify Fisher, orally and in
writing, if it enters into discussions or negotiations concerning any
Alternative Transaction Proposal in accordance with Section 4.2(a).

                                      -60-


               (c) Nothing contained in this Section 4.2 shall prohibit Fisher
or Thermo Electron or their respective Subsidiaries from taking and disclosing
to their respective stockholders a position required by Rule 14e-2(a) or Rule
14d-9 promulgated under the Exchange Act.

               (d) Fisher and its Subsidiaries, and Thermo Electron and its
Subsidiaries, respectively, shall immediately cease and cause to be terminated
any existing discussions or negotiations with any Persons (other than Fisher or
Thermo Electron, respectively) conducted heretofore with respect to any of the
foregoing, and shall use reasonable best efforts to cause all Persons other than
Fisher or Thermo Electron who have been furnished confidential information
regarding Fisher or Thermo Electron in connection with the solicitation of or
discussions regarding an Alternative Transaction Proposal within the 12 months
prior to the date hereof promptly to return or destroy such information. Fisher
and Thermo Electron agree not to, and to cause their respective Subsidiaries not
to, release any third party from the confidentiality and standstill provisions
of any agreement to which Fisher or Thermo Electron or their respective
Subsidiaries is or may become a party.

               (e) Fisher and Thermo Electron shall use their respective
reasonable best efforts to inform their respective Representatives of the
restrictions described in this Section 4.2. It is understood that any violation
of the restrictions set forth in this Section 4.2 by any officer, director,
employee, agent or representative (including any investment banker, financial
advisor, attorney, accountant or other retained representative) of Fisher or its
Subsidiaries, or Thermo Electron or its Subsidiaries, respectively, at the
direction or with the consent of Fisher or Thermo Electron, respectively, or
their respective Subsidiaries, as the case may be, shall be deemed to be a
breach of this Section 4.2 by Fisher or Thermo Electron, respectively.

                                   ARTICLE V

                              ADDITIONAL AGREEMENTS

         SECTION 5.1. Preparation of SEC Documents; Stockholders' Meetings.

               (a) As soon as practicable following the date of this Agreement,
Thermo Electron and Fisher shall prepare and file with the SEC the Joint Proxy
Statement, and Thermo Electron shall prepare and file with the SEC the Form S-4,
in which the Joint Proxy Statement will be included as a prospectus. Each of
Thermo Electron and Fisher shall use reasonable best efforts to have the Form
S-4 declared effective under the Securities Act as promptly as practicable after
such filing. Thermo Electron will use reasonable best efforts to cause the Joint
Proxy Statement to be mailed to Thermo Electron's stockholders, and Fisher will
use reasonable best efforts to cause the Joint Proxy Statement to be mailed to
Fisher's stockholders, in each case as promptly as practicable after the Form
S-4 is declared effective under the Securities Act. Thermo Electron shall also
take any action (other than qualifying to do business in any jurisdiction in
which it is not now so qualified or filing a general consent to service of
process) required to be taken under any applicable state securities laws in
connection with the issuance and reservation of shares of Thermo Electron Common
Stock in the Merger and the conversion of Fisher Options into options to acquire
Thermo Electron Common Stock, and Fisher shall furnish all information
concerning Fisher and the holders of Fisher Common Stock as may be

                                      -61-


reasonably requested in connection with any such action. No filing of, or
amendment or supplement to, the Form S-4 or the Joint Proxy Statement will be
made by Thermo Electron or Fisher, as applicable, without the other's prior
consent (which shall not be unreasonably withheld) and without providing the
other the opportunity to review and comment thereon. Thermo Electron or Fisher,
as applicable, will advise the other promptly after it receives oral or written
notice thereof, of the time when the Form S-4 has become effective or any
supplement or amendment has been filed, the issuance of any stop order, the
suspension of the qualification of the Thermo Electron Common Stock issuable in
connection with the Merger for offering or sale in any jurisdiction, or any oral
or written request by the SEC for amendment of the Joint Proxy Statement or the
Form S-4 or comments thereon and responses thereto or requests by the SEC for
additional information and will promptly provide the other with copies of any
written communication from the SEC or any state securities commission. If at any
time prior to the Effective Time any information relating to Thermo Electron or
Fisher, or any of their respective Affiliates, officers or directors, should be
discovered by Thermo Electron or Fisher which should be set forth in an
amendment or supplement to any of the Form S-4 or the Joint Proxy Statement, so
that any of such documents would not include any misstatement of a material fact
or omit to state any material fact necessary to make the statements therein, in
light of the circumstances under which they were made, not misleading, the party
which discovers such information shall promptly notify the other parties hereto
and an appropriate amendment or supplement describing such information shall be
promptly filed with the SEC and, to the extent required by law, disseminated to
the respective stockholders of Thermo Electron and Fisher.

               (b) Each of Fisher and Thermo Electron shall, as promptly as
practicable after the Form S-4 is declared effective under the Securities Act,
take all action necessary in accordance with Applicable Laws and the Fisher
Organizational Documents, in the case of Fisher, and the Thermo Electron
Organizational Documents, in the case of Thermo Electron, to duly give notice
of, convene and hold a meeting of their stockholders, respectively, to be held
as promptly as practicable to consider, in the case of Thermo Electron, the
Stock Issuance and the Charter Amendment (the "Thermo Electron Stockholders'
Meeting") and, in the case of Fisher, the adoption and approval of this
Agreement and the Merger (the "Fisher Stockholders' Meeting"). Each of Fisher
and Thermo Electron will use reasonable best efforts to solicit from their
stockholders, respectively, proxies in favor of, in the case of Thermo Electron,
the Stock Issuance and the Charter Amendment, and, in the case of Fisher, the
adoption and approval of this Agreement and the Merger, and will take all other
action necessary or advisable to secure the vote or consent of their
stockholders, respectively, required by the rules of the NYSE or Applicable Laws
to obtain such approvals. Notwithstanding anything to the contrary contained in
this Agreement, Fisher or Thermo Electron may adjourn or postpone the Fisher
Stockholders' Meeting or Thermo Electron Stockholders' Meeting, as the case may
be, to the extent necessary to ensure that any necessary supplement or amendment
to the Joint Proxy Statement is provided to their respective stockholders, in
advance of a vote on, in the case of Thermo Electron, the Stock Issuance and the
Charter Amendment and, in the case of Fisher, the approval and adoption of this
Agreement and the Merger, or, if, as of the time for which the Fisher
Stockholders' Meeting or Thermo Electron Stockholders' Meeting, as the case may
be, is originally scheduled, there are insufficient shares of Fisher Common
Stock or Thermo Electron Common Stock, as the case may be, represented (either
in person or by proxy) to constitute a quorum necessary to conduct the business
of such meeting. Each of Fisher and Thermo Electron shall ensure that the Fisher
Stockholders' Meeting and the Thermo Electron Stockholders'

                                      -62-


Meeting, respectively, is called, noticed, convened, held and conducted, and
that all proxies solicited in connection with the Fisher Stockholders' Meeting
or Thermo Electron Stockholders' Meeting, as the case may be, are solicited in
compliance with Applicable Laws, the rules of the NYSE and, in the case of
Fisher, the Fisher Organizational Documents, and, in the case of Thermo
Electron, the Thermo Electron Organizational Documents. Except with respect to
matters as to which preliminary proxy materials would not be required to be
filed with the SEC, without the prior written consent of Fisher, the Stock
Issuance and the Charter Amendment are the only matters which Thermo Electron
shall propose to be acted on by Thermo Electron's stockholders at the Thermo
Electron Stockholders' Meeting. Without the prior written consent of Thermo
Electron, approval and adoption of this Agreement and the Merger are the only
matters which Fisher shall propose to be acted on by Fisher's stockholders at
the Fisher Stockholders' Meeting.

               (c) Each of Fisher and Thermo Electron will use reasonable best
efforts to hold the Fisher Stockholders' Meeting and Thermo Electron
Stockholders' Meeting, respectively, on the same date as the other party and as
soon as reasonably practicable after the date of this Agreement.

         SECTION 5.2. Accountant's Letters. Each of Fisher and Thermo Electron
shall use reasonable best efforts to cause to be delivered to the other party
two letters from their respective independent accountants, one dated
approximately as of the date the Form S-4 is declared effective and one dated
approximately as of the Closing Date, each addressed to the other party, in form
and substance reasonably satisfactory to the other party and customary in scope
and substance for comfort letters delivered by independent public accountants in
connection with registration statements similar to the Form S-4.

         SECTION 5.3. Access to Information; Confidentiality.

               (a) Subject to the CDA and Applicable Laws, each of Thermo
Electron and Fisher shall, and shall cause each of their respective Subsidiaries
to, afford to the other party and to the officers, employees, accountants,
counsel, financial advisors and other representatives of such other party,
reasonable access at all reasonable times on reasonable notice during the period
prior to the Effective Time to all their respective properties, books,
contracts, commitments, personnel and records (provided, that such access shall
not unreasonably interfere with the business or operations of such party) and,
during such period and subject to the CDA and Applicable Laws, each of Thermo
Electron and Fisher shall, and shall cause each of their respective Subsidiaries
to, make available to the other party (i) a copy of each material report,
schedule, registration statement and other document filed by it during such
period pursuant to the requirements of federal or state securities laws and (ii)
all other material information concerning its business, properties and personnel
as such other party may reasonably request. No review pursuant to this Section
5.3 shall affect or be deemed to modify any representation or warranty contained
herein, the covenants or agreements of the parties hereto or the conditions to
the obligations of the parties hereto under this Agreement.

               (b) Each of Thermo Electron and Fisher will hold and keep
confidential, and will cause their respective officers and employees and will
direct its

                                      -63-


accountants, counsel, financial advisors and other representatives and
Affiliates to hold and keep confidential, any nonpublic information in
accordance with the terms of the CDA.

         SECTION 5.4. Reasonable Best Efforts.

               (a) Upon the terms and subject to the conditions set forth in
this Agreement, each of the parties agrees to use their reasonable best efforts
to take, or cause to be taken, all actions, and to do, or cause to be done, and
to assist and cooperate with the other parties in doing, all things necessary,
proper or advisable under Applicable Laws to consummate and make effective, in
the most expeditious manner practicable, the Merger and the other transactions
contemplated by this Agreement, including (i) the obtaining of all necessary
actions or non-actions, waivers, consents and approvals from Governmental
Entities and the making of all necessary registrations and filings and the
taking of all steps as may be necessary to obtain an approval or waiver from, or
to avoid an action or proceeding by, any Governmental Entity, including all
filings required under the HSR Act, with the Federal Trade Commission or the
United States Department of Justice, all notifications and other filing required
under the ECMR and any other necessary antitrust, competition or similar laws of
any foreign jurisdiction, (ii) the obtaining of all necessary consents,
approvals or waivers, (iii) the defending of any lawsuits or other legal
proceedings, whether judicial or administrative, challenging this Agreement or
the consummation of the transactions contemplated by this Agreement, including
promptly seeking to have any stay or temporary restraining order entered by any
court or other Governmental Entity vacated or reversed, and (iv) the execution
and delivery of any additional instruments necessary to consummate the
transactions contemplated by, and to fully carry out the purposes of, this
Agreement. In furtherance of the foregoing, the parties shall cooperate and use
reasonable best efforts to determine and agree upon, within two weeks of the
date hereof, a list of those Governmental Entities in foreign jurisdictions to
which it may be necessary or appropriate to submit any filings, notifications or
registrations or take any other actions in connection with regulatory or legal
requirements of such Governmental Entities relating to the transactions
contemplated hereby; provided that the foregoing shall not affect or otherwise
modify the closing conditions in Sections 6.1(b) and (c). Subject to Applicable
Laws relating to the exchange of information, Fisher and Thermo Electron shall
have the right to review in advance, and to the extent reasonably practicable
each will consult the other on, all the information relating to Fisher and its
Subsidiaries or Thermo Electron and its Subsidiaries, as the case may be, that
appears in any filing made with, or written materials submitted to, any
Governmental Entity in connection with the Merger and the other transactions
contemplated by this Agreement.

               (b) Each of Thermo Electron and Fisher shall keep the other
reasonably apprised of the status of matters relating to the completion of the
transactions contemplated hereby and work cooperatively in connection with
obtaining all required approvals or consents of any Governmental Entity. In that
regard, each party shall without limitation: (i) promptly notify the other of,
and if in writing, furnish the other with copies of (or, in the case of oral
communications, advise the other orally of) any communications from or with any
Governmental Entity with respect to the Merger or any of the other transactions
contemplated by this Agreement, (ii) permit the other to review and discuss in
advance, and consider in good faith the views of the other in connection with,
any proposed written (or any proposed oral) communication with any such
Governmental Entity with respect to the Merger or any of the other transactions
contemplated by this Agreement, (iii) not participate in any meeting or oral

                                      -64-


communication with any such Governmental Entity with respect to the Merger or
any of the other transactions contemplated by this Agreement unless it consults
with the other in advance and, to the extent permitted by such Governmental
Entity, gives the other the opportunity to attend and participate thereat, (iv)
furnish the other with copies of all correspondence, filings and communications
(and memoranda setting forth the substance thereof) between it and any such
Governmental Entity with respect to the Merger or any of the other transactions
contemplated by this Agreement and the Merger, and (v) furnish the other with
such necessary information and reasonable assistance as the other may reasonably
request in connection with its preparation of necessary filings or submissions
of information to any such Governmental Entity. Each of Thermo Electron and
Fisher may, as each deems advisable and necessary, reasonably designate any
competitively sensitive material provided to the other under this Section 5.4 as
"outside counsel only." Such material and the information contained therein
shall be given only to the outside legal counsel of the recipient and will not
be disclosed by such outside counsel to employees, officers, or directors of the
recipient unless express permission is obtained in advance from the source of
the materials (Thermo Electron or Fisher, as the case may be) or its legal
counsel.

               (c) In connection with and without limiting the foregoing, Thermo
Electron and Fisher shall (i) take all action necessary to ensure that no state
takeover statute or similar statute or regulation is or becomes applicable to
this Agreement or any of the transactions contemplated hereby and (ii) if any
state takeover statute or similar statute or regulation becomes applicable to
this Agreement or any of the transactions contemplated hereby, take all action
necessary to ensure that such transactions may be consummated as promptly as
practicable on the terms required by, or provided for, in this Agreement and
otherwise to minimize the effect of such statute or regulation on the Merger and
the other transactions contemplated by this Agreement.

               (d) In connection with the filings referenced in Section 5.4(a)
and (b), the parties shall cooperate with each other and use their respective
reasonable best efforts to promptly prepare and file all necessary
documentation, to effect all applications, notices, petitions and filings, to
obtain as promptly as practicable all permits, consents, approvals and
authorizations of all Governmental Entities that are necessary or advisable to
consummate the transactions contemplated by this Agreement (including the
Merger), and to comply with the terms and conditions of all such permits,
consents, approvals and authorizations of all such third parties or Governmental
Entities. Notwithstanding the foregoing, nothing contained herein shall be
deemed to require Thermo Electron or Fisher to take any action, or commit to
take any action, or agree to any condition or restriction, in connection with
obtaining the foregoing permits, consents, approvals and authorizations of
Governmental Entities, that would reasonably be expected to have a material
adverse effect (measured on a scale relative to Thermo Electron in the case of
Thermo Electron and Fisher in the case of Fisher) on either Thermo Electron or
Fisher, respectively.

               (e) Fisher and its Subsidiaries shall, upon reasonable notice,
provide, and shall cause their respective officers, employees and
representatives to provide, all cooperation reasonably requested by Thermo
Electron in connection with (i) the repayment, repurchase, redemption,
defeasance, modification, refinancing, or assumption, of all rights, duties and
obligations, contingent or otherwise, of Fisher and its Subsidiaries in respect
of the

                                      -65-


Fisher financings described in Section 5.4(e) of the Fisher Disclosure Schedule
and (ii) the contemplated Thermo Electron financings identified in Section
5.4(e) of the Thermo Electron Disclosure Schedule; provided that,
notwithstanding the foregoing, no request for cooperation or other assistance
shall be required if it would unreasonably disrupt the business or operations of
Fisher or any of its Subsidiaries.

         SECTION 5.5. Indemnification and Insurance.

               (a) From and after the Effective Time, Thermo Electron will, and
will cause the Surviving Corporation to, fulfill and honor in all respects the
obligations of Fisher pursuant to any indemnification agreements between Fisher
and its present or former directors, officers and employees in effect
immediately prior to the Effective Time, subject to Applicable Laws. For at
least six years after the Effective Time, Thermo Electron shall, and shall cause
the Surviving Corporation to, indemnify and hold harmless the present and former
officers and directors of Fisher and its Subsidiaries (the "Indemnified
Parties") for any costs, judgments, fines, losses, claims, damages or
liabilities incurred in connection with any claim, action, suit or proceeding
(whether civil, criminal, administrative or investigative) by reason of the fact
that such Person is or was an officer, director or employee of Fisher or any of
its Subsidiaries in respect of acts or omissions occurring at or prior to the
Effective Time (including those related to this Agreement and the transactions
contemplated hereby), and shall advance expenses in respect thereof, in each
case, to the fullest extent permitted by Applicable Laws.

               (b) For a period of six years after the Effective Time, the
Surviving Corporation shall cause to be maintained in effect the current
policies of directors' and officers' and fiduciary liability insurance
maintained by Fisher with respect to claims arising from facts or events which
occurred on or before the Effective Time (including those related to this
Agreement and the transactions contemplated hereby); provided, that the
Surviving Corporation may substitute therefor policies of at least the same
coverage and amounts containing terms and conditions which are no less
advantageous to former officers and directors of Fisher only with respect to
claims arising from facts or events which occurred at or before the Effective
Time; and provided, further, that if the aggregate annual premiums for such
policies at any time during such period will exceed 250% of the per annum
premium rate paid by Fisher and its Subsidiaries as of the date hereof for such
policies, then Thermo Electron shall be required to provide as much coverage as
is then available at such annual premium.

               (c) Notwithstanding anything herein to the contrary and to the
maximum extent permitted by Applicable Laws, if any claim, action, suit,
proceeding or investigation is made or brought against any Indemnified Party on
or prior to the sixth anniversary of the Effective Time, the provisions of this
Section 5.5 shall continue in effect until the final disposition of such claim,
action, suit, proceeding or investigation.

               (d) If Thermo Electron, the Surviving Corporation or any of their
respective successors or assigns (i) shall consolidate with or merge into any
other Person and shall not be the continuing or surviving corporation or entity
of such consolidation or merger or (ii) shall transfer all or substantially all
of its properties or assets to any Person, then, in each case, Thermo Electron
shall take such action as may be necessary so that such Person shall assume all
of the applicable obligations set forth in this Section 5.5.

                                      -66-


               (e) The provisions of this Section 5.5 are (i) intended to be for
the benefit of, and shall be enforceable by, each Indemnified Party, his or her
heirs and representatives and (ii) in addition to, and not in substitution for,
any other rights to indemnification or contribution that any such Person may
have by contract or otherwise.

         SECTION 5.6. Fees and Expenses. Except as set forth in this Section 5.6
and in Section 7.2, all fees and expenses incurred in connection with the
Merger, this Agreement and the transactions contemplated by this Agreement shall
be paid by the party incurring such fees or expenses, whether or not the Merger
is consummated, except that each of Fisher and Thermo Electron shall bear and
pay one-half of the costs and expenses incurred by Thermo Electron, Merger Sub
or Fisher (other than attorneys' fees, accountants' fees and related expenses)
in connection with (i) the filing, printing and mailing of the Form S-4
(including financial statements and exhibits), the Joint Proxy Statement
(including SEC filing fees) and any preliminary materials related thereto and
(ii) the filings of the premerger notification and report forms under the HSR
Act and any applicable antitrust, competition or similar laws of any foreign
jurisdiction (including filing fees).

         SECTION 5.7. Public Announcements. Neither Fisher nor Thermo Electron
shall, and neither Fisher nor Thermo Electron shall permit any of their
respective Subsidiaries to, issue or cause the publication of any press release
or other public announcement with respect to, or otherwise make any public
statement concerning, the transactions contemplated by this Agreement without
the prior consent (which consent shall not be unreasonably withheld) of Thermo
Electron, in the case of a proposed announcement or statement by Fisher, or
Fisher, in the case of a proposed announcement or statement by Thermo Electron;
provided, however, that either party may, without the prior consent of the other
party (but after prior consultation with the other party to the extent
practicable under the circumstances) issue or cause the publication of any press
release or other public announcement to the extent required by law or by the
rules and regulations of the NYSE.

         SECTION 5.8. Listing. Thermo Electron shall use reasonable best efforts
to cause the Thermo Electron Common Stock issuable under Article II, and those
shares of Thermo Electron Common Stock required to be reserved for issuance in
connection with the Merger, to be authorized for listing on the NYSE, upon
official notice of issuance.

         SECTION 5.9. Tax-Free Reorganization Treatment. Thermo Electron and
Fisher hereby adopt this Agreement as a plan of reorganization within the
meaning of Treasury Regulations Sections 1.368-2(g) and 1.368-3(a). Thermo
Electron and Fisher intend that the Merger will qualify as a reorganization
within the meaning of Section 368(a) of the Code, and each shall, and shall
cause their respective Subsidiaries to, use its reasonable best efforts to cause
the Merger to so qualify. Neither Thermo Electron, Merger Sub nor Fisher shall
take any action, cause or permit any action to be taken, or fail to take any
action, that would reasonably be expected to cause the Merger to fail to qualify
as a reorganization within the meaning of Section 368(a) of the Code.

         SECTION 5.10. Conveyance Taxes. Fisher and Thermo Electron shall
cooperate in the preparation, execution and filing of all returns,
questionnaires, applications or other documents regarding any real property
transfer or gains, sales, use, transfer, value added,

                                      -67-


stock transfer and stamp taxes, any transfer, recording, registration and other
fees or any similar taxes which become payable in connection with the
transactions contemplated by this Agreement that are required or permitted to be
filed on or before the Effective Time.

         SECTION 5.11. Equity Awards and Employee Benefits.

               (a) Equity Awards. Fisher Options. At the Effective Time, each
then outstanding Fisher Option, whether or not exercisable at the Effective
Time, will be assumed by Thermo Electron. Subject to, and in accordance with,
the terms of the applicable Fisher Stock Plan and option award agreement, each
Fisher Option so assumed by Thermo Electron under this Agreement will otherwise
continue to have, and be subject to, the same terms and conditions set forth in
the applicable Fisher Option (including any applicable option award agreement or
other document evidencing such Fisher Option) immediately prior to the Effective
Time (including any vesting or forfeiture provisions or repurchase rights, but
taking into account any acceleration of Fisher Options pursuant to any Fisher
Benefit Plan or applicable option award agreement), except that (A) each Fisher
Option, when exercisable, will be exercisable for that number of whole shares of
Thermo Electron Common Stock equal to the product of the number of shares of
Fisher Common Stock that were subject to such Fisher Option immediately prior to
the Effective Time multiplied by the Exchange Ratio, rounded down to the nearest
whole number of shares of Thermo Electron Common Stock and (B) the per share
exercise price for the shares of Thermo Electron Common Stock issuable upon
exercise of such assumed Fisher Option will be equal to the quotient determined
by dividing the exercise price per share of Fisher Common Stock of such Fisher
Option by the Exchange Ratio, rounded up to the nearest whole cent.

                   (ii) Fisher Stock Unit Awards. At the Effective Time, each
      Fisher Stock Unit Award then outstanding shall be assumed by Thermo
      Electron. Subject to, and in accordance with, the terms of the applicable
      Fisher Stock Plan or Fisher Deferred Compensation Plan and any applicable
      award or other agreement, each Fisher Stock Unit Award shall be converted
      into the right to receive the number of shares of Thermo Electron Common
      Stock (or an amount in respect thereof for cash settled Fisher Stock Unit
      Awards) equal to the number of shares of Fisher Common Stock subject to
      the Fisher Stock Unit Award, multiplied by the Exchange Ratio (rounded
      down to the nearest whole number of shares of Thermo Electron Common
      Stock). Each Fisher Stock Unit Award shall have the same terms and
      conditions as were in effect immediately prior to the Effective Time,
      except that the performance conditions applicable to the vesting of the
      assumed Fisher Stock Unit Awards shall be deemed to have been satisfied
      effective as of the Closing Date, and such Fisher Stock Unit Awards (other
      than those granted under the Fisher 2005 Equity and Incentive Plan) that
      are evidenced by a Performance Based Restricted Stock Unit Purchase
      Agreement and which become vested and payable in accordance with their
      current terms upon a change in control transaction (for this purpose
      taking into account Section 5.11(e) hereof) (the holders of which and the
      related number of units are identified on a list which Fisher has
      delivered to Thermo Electron prior to the date hereof), shall instead vest
      and be settled in three equal increments on the first three anniversaries
      of the original grant date of the Fisher Stock Unit Award, subject to the
      holder's continued employment with Thermo Electron or the Surviving
      Corporation or their Subsidiaries as of each such vesting date, unless,
      following the Closing Date, the holder of the Fisher Stock Unit Award is
      terminated prior to the full vesting of the Fisher Stock Unit Award either
      without Cause or for Good Reason

                                      -68-


      (as each such term is defined in Fisher's 2005 Equity and Incentive Plan),
      in which case the Fisher Stock Unit Award will vest immediately upon such
      termination of employment. Fisher Stock Unit Awards described in this
      Section 5.11(a)(ii) that vest upon a termination of employment as
      described in the previous sentence shall be settled upon the earliest date
      following the applicable vesting date which will not cause an imposition
      of any additional tax under Section 409A of the Code.

                   (iii) Fisher and Thermo Electron agree that prior to the
      Effective Time, Fisher shall, and shall be permitted under this Agreement,
      to take all corporate action necessary, including, but not limited to,
      amending any Fisher Option, Fisher Stock Unit Award or Fisher equity award
      agreement evidencing such award, or Fisher Stock Plan or Fisher Deferred
      Compensation Plan, (A) to effectuate the provisions of Section 5.11(a)(i)
      and Section 5.11(a)(ii) and (B) to the extent applicable, to preclude any
      automatic or formulaic grant of options, restricted shares or other awards
      thereunder on or after the date hereof other than pursuant to the Fisher
      Purchase Plan as in effect on the date hereof. From and after the
      Effective Time, all references to Fisher (other than any references
      relating to a "change in control" of Fisher) in each Fisher Stock Plan,
      Fisher Deferred Compensation Plan and in each agreement evidencing any
      Fisher Options or Fisher Stock Unit Awards shall be deemed to refer to
      Thermo Electron, unless Thermo Electron determines otherwise. As soon as
      reasonably practicable, but in no event later than ten business days
      following the Effective Time, Thermo Electron will (A) issue to each
      holder of an assumed Fisher Option or Fisher Stock Unit Award a document
      evidencing the foregoing assumption of such Fisher Option or Fisher Stock
      Unit Award by Thermo Electron, (B) issue appropriate notices setting forth
      such holders' rights pursuant to the assumed Fisher Options or Fisher
      Stock Unit Awards, and (C) issue appropriate notices to each holder of an
      assumed Fisher Option or Fisher Stock Unit Award setting forth the effect
      of the Merger on the Fisher Options or Fisher Stock Unit Awards. Prior to
      the Effective Time, Thermo Electron shall take all corporate action
      necessary to reserve for issuance a sufficient number of shares of Thermo
      Electron Common Stock for delivery in connection with the exercise of the
      converted Fisher Options and Fisher Stock Unit Awards. The parties shall
      use their reasonable best efforts to ensure that the conversion of any
      Fisher Options which are intended to be "incentive stock options" (as
      defined in Section 422 of the Code) provided for in Section 5.11(a)(i)
      shall be effected in a manner consistent with Section 424(a) of the Code.

                   (iv) Within one business day of the Closing Date, Thermo
      Electron shall register the shares of Thermo Electron Common Stock subject
      to Fisher Options and Fisher Stock Unit Awards by filing an effective
      registration statement on Form S-8 (or any successor form) or another
      appropriate form, and Thermo Electron shall maintain the effectiveness of
      such registration statement or registration statements with respect
      thereto for so long as such awards remain outstanding. Following the
      Closing Date, Thermo Electron may grant equity awards under the Fisher
      Stock Plans, to the extent shares are available for grant under any such
      plan, in accordance with the mergers and acquisitions exemption to the
      equity compensation plan shareholder approval requirement under the NYSE
      rules.

                   (v) Notwithstanding the foregoing, Thermo Electron shall not
      be required to take any of the actions contemplated by this Section
      5.11(a) if, and to the extent that, such action does not comply with the
      Applicable Law of any foreign jurisdiction.

                                      -69-


               (b) Fisher shall terminate the Fisher Purchase Plan at least one
full payroll period prior to the Effective Time. To the extent any offering
period under the Fisher Purchase Plan is in progress prior to such termination,
Fisher shall ensure that such offering period ends immediately prior to such
termination, and that each participant's accumulated contributions for such
offering period are applied towards the purchase of Fisher Common Stock
immediately prior to such termination unless the participant has previously
withdrawn from such offering period in accordance with the terms of such plan.

               (c) This Section 5.11(c) shall apply to each employee of Fisher
or its Subsidiaries as of immediately prior to the Effective Time other than
Represented Employees (as defined in Section 5.12) (the "Fisher Employees").
Following the Closing Date, and for two years thereafter, but in no event later
than such time as a Fisher Employee ceases to be employed by or provide services
to Thermo Electron or the Surviving Corporation or their Subsidiaries following
the Effective Time, Thermo Electron shall provide, or cause to be provided, the
Fisher Employees, benefits and compensation (other than stock options or other
equity-based incentive plans, programs, agreements or arrangements) that in the
aggregate are substantially no less favorable than the benefits provided, in
the aggregate, to such individuals by Fisher and its Subsidiaries; it being
understood that the Fisher Employees may commence participating in the Thermo
Electron Benefit Plans on different dates following the Closing Date with
respect to different Thermo Electron Benefit Plans. Thermo Electron shall give
Fisher Employees full credit for purposes of eligibility, vesting, determination
of the level of benefits and benefit accrual under any employee benefit plans or
arrangements maintained by Thermo Electron or any Subsidiary for such Fisher
Employees' service with Fisher and its Subsidiaries (and service with any
predecessor, to the extent recognized by Fisher or its Subsidiaries) prior to
the Closing Date, except to the extent that such crediting would result in
duplication of benefits and provided that no prior service credit shall be
recognized for purposes of (i) benefit accrual, level of pay credits and/or
grandfathering under any defined benefit plan or (ii) post-retirement welfare
benefits. Thermo Electron shall (i) waive all limitations as to preexisting
conditions exclusions and waiting periods with respect to participation and
coverage requirements applicable to the Fisher Employees under any welfare
benefit plans that such employees may be eligible to participate in after the
Effective Time, other than limitations or waiting periods that are already in
effect with respect to such employees and that have not been satisfied as of the
Effective Time under any welfare plan maintained for the Fisher Employees
immediately prior to the Closing Date, and (ii) provide each Fisher Employee
with credit for any co-payments and deductibles paid under any Fisher Benefit
Plan that provides healthcare benefits in the plan year in effect as of the
Closing Date in satisfying any applicable deductible or out-of-pocket
requirements under any healthcare plans of Thermo Electron or the Surviving
Corporation that such employees are eligible to participate in after the
Effective Time to the same extent that such expenses were recognized under the
comparable Fisher Benefit Plan.

               (d) Notwithstanding anything in this Agreement to the contrary,
no provision of this Agreement shall be deemed to (i) guarantee employment for
any period of time for, or preclude the ability of either party to terminate,
any Fisher Employee for any reason or (ii) subject to the limitations and
requirements specifically set forth in this Section 5.11, require either party
to continue any Thermo Electron Benefit Plan or Fisher Benefit Plan or prevent
the amendment, modification or termination thereof after the Effective Time.

                                      -70-


               (e) Without limiting the generality of the foregoing, as of the
Effective Time, Thermo Electron shall cause the Surviving Corporation and its
Subsidiaries to honor in accordance with their terms all employment, change in
control, severance and other compensation agreements and arrangements existing
prior to the execution of this Agreement which are between Fisher or any
Subsidiary and any director, officer or employee thereof and set forth in
Section 5.11(e) of the Fisher Disclosure Schedule (each a "Fisher Executive
Agreement"); provided, that, nothing herein shall prevent Thermo Electron from
amending any such agreement or plan in accordance with its terms, including such
amendments as may be necessary to avoid the imposition of a tax under Section
409A of the Code. Fisher and Thermo Electron hereby agree that the occurrence of
the Closing shall constitute a "Change in Control" for purposes of any Fisher
Executive Agreement and all Fisher Benefit Plans and related trusts set forth in
Section 5.11(e) of the Fisher Disclosure Schedule.

               (f) Fisher shall be entitled to pay or provide for cash bonus
payments in an aggregate amount not to exceed the amount set forth in Section
5.11(f) of the Fisher Disclosure Schedule, to such individuals, in such amounts
and upon such terms and conditions as Fisher may determine consistent with such
schedule.

               (g) As soon as practicable following the date hereof (but in any
event within 30 days hereof), the Board of Directors of Thermo Electron shall,
in consultation with Fisher and with Fisher's approval (which shall not be
unreasonably withheld), establish a long-term incentive compensation program for
Thermo Electron senior management, which awards shall provide each such employee
with unvested long-term incentive compensation that is comparable in aggregate
value to the currently unvested (but with accelerated vesting upon the
consummation of the transactions contemplated by this Agreement) equity-based
and other long-term incentive compensation that is now held by such employee.

               (h) Following the date hereof, but in no event later that 30 days
following the date hereof, Fisher shall take action with respect to the plan
identified in Section 5.11(h) of the Fisher Disclosure Schedule in the manner
set forth in such Schedule.

         SECTION 5.12. Honoring of Collective Bargaining Agreements; Represented
Employees. With respect to any continuing employee whose terms and conditions of
employment are governed by any of the collective bargaining agreements listed on
Section 3.1(h)(ii) of the Fisher Disclosure Schedule (each a "Represented
Employee"), Thermo Electron agrees to honor or cause to be honored the
collective bargaining agreements listed on Section 3.1(h)(ii) of the Fisher
Disclosure Schedule as of the Closing Date and to continue all terms and
conditions of employment applicable to such Represented Employees under their
respective collective bargaining agreements through the expiration, modification
or termination of such agreements in conformity with Applicable Law.

         SECTION 5.13. Affiliates. Fisher shall use its reasonable efforts to
cause each Person who is, in Fisher's reasonable judgment, an "affiliate" of
Fisher within the meaning of Rule 145 promulgated under the Securities Act
("Rule 145 Affiliates") to deliver to Thermo Electron, as soon as reasonably
practicable and in any event prior to the meeting of Fisher stockholders to be
held pursuant to Section 5.1(b), a written agreement substantially in the form
attached as Exhibit 5.13. Thermo Electron shall be entitled to place appropriate
legends

                                      -71-


(reasonably acceptable to Fisher) on the certificates evidencing any shares of
Thermo Electron Common Stock to be received by Rule 145 Affiliates in the Merger
reflecting the restrictions set forth in Rule 145 promulgated under the
Securities Act and to issue appropriate stop transfer instructions to the
transfer agent for Thermo Electron Common Stock (provided, that such legends or
stop transfer instructions shall be removed, one year after the Effective Time,
upon the request of any holder of shares of Thermo Electron Common Stock issued
in the Merger if such holder is not then a Rule 145 Affiliate).

         SECTION 5.14. Notification of Certain Matters. Thermo Electron shall
give prompt notice to Fisher and Fisher shall give prompt notice to Thermo
Electron, as the case may be, of the occurrence, or failure to occur, of any
event, which occurrence or failure to occur would reasonably be expected to
cause (a)(i) any representation or warranty of such party contained in this
Agreement that is qualified as to "materiality" or "Material Adverse Effect" to
be untrue or inaccurate in any respect or (ii) any other representation or
warranty of such party contained in this Agreement that is not qualified as to
"materiality" or "Material Adverse Effect" to be untrue or inaccurate in any
material respect, in each case at any time from and after the date of this
Agreement until the Effective Time, or (b) any material failure of Thermo
Electron and the Merger Sub or Fisher, as the case may be, to comply with or
satisfy any covenant, condition or agreement to be complied with or satisfied by
it under this Agreement. In addition, Thermo Electron shall give prompt notice
to Fisher and Fisher shall give prompt notice to Thermo Electron, as the case
may be, of any change or event having, or which would reasonably be expected to
have, a Material Adverse Effect on such party and its Subsidiaries, taken as a
whole, or which would reasonably be expected to result in the failure of any of
the conditions set forth in Article VI to be satisfied. Notwithstanding the
above, the delivery of any notice pursuant to this Section 5.14 will not limit
or otherwise affect the remedies available hereunder to the party receiving such
notice or the conditions to such party's obligation to consummate the Merger.

         SECTION 5.15. Section 16 Matters. Prior to the Effective Time, each of
Thermo Electron and Fisher shall use their reasonable best efforts to take all
such steps as may be required (to the extent permitted under Applicable Laws) to
cause any dispositions of Fisher Common Stock (including derivative securities)
or acquisitions of Thermo Electron Common Stock (including derivative securities
with respect to Thermo Electron Common Stock) resulting from the transactions
contemplated by this Agreement by each individual who is subject to the
reporting requirements of Section 16(a) of the Exchange Act with respect to
Fisher to be exempt under Rule 16b-3 promulgated under the Exchange Act.

         SECTION 5.16. State Takeover Laws. Prior to the Effective Time, neither
Fisher nor Thermo Electron shall take any action to render inapplicable, or to
exempt any third Person from, any state takeover law or state law that purports
to limit or restrict business combinations or the ability to acquire or vote
shares of capital stock unless (i) required to do so by order of a court of
competent jurisdiction or (ii) Thermo Electron's or Fisher's Board of Directors,
as the case may be, has concluded in good faith, after consultation with its
outside legal counsel, that the failure to take such action is reasonably likely
to result in a breach of its Board of Directors' fiduciary obligations to their
stockholders, respectively, under Applicable Laws.

                                      -72-


         SECTION 5.17. Reservation of Thermo Electron Common Stock. Effective at
or prior to the Effective Time, Thermo Electron shall reserve (free from
preemptive rights) out of its reserved but unissued or treasury shares of Thermo
Electron Common Stock, for the purposes of effecting the conversion of the
issued and outstanding shares of Fisher Common Stock pursuant to this Agreement,
sufficient shares of Thermo Electron Common Stock to provide for such conversion
as well as the issuance of Thermo Electron Common Stock upon the exercise or
settlement of Fisher Options and Fisher Stock Unit Awards assumed by Thermo
Electron under Section 5.11.

                                   ARTICLE VI

                              CONDITIONS PRECEDENT

Merger. The obligation of each party to effect the Merger is subject to the
satisfaction or waiver at or prior to the Closing of the following conditions:

               (a) Stockholder Approvals. Each of the Thermo Electron
Stockholder Approval and the Fisher Stockholder Approval shall have been
obtained.

               (b) Antitrust Waiting Periods. The waiting periods (and any
extensions thereof) and any approvals applicable to the Merger under (i) the HSR
Act, and (ii) the ECMR shall have been terminated or shall have expired or shall
have been obtained, as applicable.

               (c) Consents and Approvals. Other than the expirations and
approvals required by Section 6.1(b), all filings with, and all consents,
approvals and authorizations of, any Governmental Entity required to be made or
obtained by Thermo Electron, Fisher or any of their respective Subsidiaries to
consummate the Merger shall have been obtained, other than such consents,
approvals and authorizations the failure of which to be made or obtained would
not, individually or in the aggregate, have a Material Adverse Effect on Fisher
and its Subsidiaries, taken as a whole, or Thermo Electron and its Subsidiaries,
taken as a whole, respectively (determined, for purposes of this clause, after
giving effect to the Merger).

               (d) No Injunctions or Restraints. No judgment, order, decree,
statute, law, ordinance, rule or regulation, or other legal restraint or
prohibition, entered, enacted, promulgated, enforced or issued by any court or
other Governmental Entity of competent jurisdiction shall be in effect that
makes illegal or prohibits the consummation of the transactions contemplated by
this Agreement.

               (e) Form S-4. The Form S-4 shall have become effective under the
Securities Act prior to the mailing of the Joint Proxy Statement by each of
Thermo Electron and Fisher to their stockholders, respectively, and no stop
order or proceedings seeking a stop order shall have been initiated or, to the
Knowledge of Thermo Electron or Fisher, threatened by the SEC.

                                      -73-


               (f) Listing. The shares of Thermo Electron Common Stock issuable
to the stockholders of Fisher as provided for in Article II shall have been
authorized for listing on the NYSE upon official notice of issuance.

         SECTION 6.2. Conditions to Obligations of Fisher. The obligation of
Fisher to effect the Merger is further subject to satisfaction or waiver at or
prior to the Closing of the following conditions:

               (a) Representations and Warranties. The representations and
warranties of Thermo Electron and Merger Sub set forth herein shall be true and
correct (without giving effect to any limitation as to "materiality" or
"Material Adverse Effect" set forth therein (other than the representation set
forth in Section 3.2(f)(ii), which shall be read with the Material Adverse
Effect qualification)) both when made and at and as of the Closing Date, as if
made at and as of such time (except to the extent expressly made as of an
earlier date, in which case as of such date), except where the failure of such
representations and warranties to be so true and correct (without giving effect
to any limitation as to "materiality" or "Material Adverse Effect" set forth
therein (other than the representation set forth in Section 3.2(f)(ii), which
shall be read with the Material Adverse Effect qualification)) does not have,
and would not reasonably be expected to have, individually or in the aggregate,
a Material Adverse Effect on Thermo Electron and its Subsidiaries, taken as a
whole.

               (b) Performance of Obligations of Thermo Electron and Merger Sub.
Each of Thermo Electron and Merger Sub shall have performed, or complied with,
in all material respects all obligations required to be performed or complied
with by it under this Agreement at or prior to the Closing Date.

               (c) No Material Adverse Effect. No Material Adverse Effect of
Thermo Electron and its Subsidiaries, taken as a whole, shall have occurred
since the date of this Agreement and be continuing.

               (d) Officer's Certificate. Fisher shall have received an
officer's certificate duly executed by each of the Chief Executive Officer and
Chief Financial Officer of Thermo Electron to the effect that the conditions set
forth in Sections 6.2(a), (b) and (c) have been satisfied.

               (e) Tax Opinion. Fisher shall have received an opinion of
Skadden, Arps, Slate, Meagher & Flom, LLP ("Fisher's Counsel"), in form and
substance reasonably satisfactory to Fisher, dated the Closing Date, to the
effect that, on the basis of facts, representations and assumptions set forth or
referred to in such opinion that are consistent with the state of facts existing
at the Effective Time, the Merger will be treated as a reorganization within the
meaning of Section 368(a) of the Code. In rendering such opinion, Fisher's
Counsel may require and rely upon representations and covenants, including those
contained in certificates of officers of Fisher, Thermo Electron and others,
reasonably satisfactory in form and substance to such counsel.

                                      -74-


         SECTION 6.3. Conditions to Obligations of Thermo Electron and Merger
Sub. The obligations of Thermo Electron and Merger Sub to effect the Merger are
further subject to satisfaction or waiver at or prior to the Closing of the
following conditions:

               (a) Representations and Warranties. The representations and
warranties of Fisher set forth herein shall be true and correct (without giving
effect to any limitation as to "materiality" or "Material Adverse Effect" set
forth therein (other than the representation set forth in Section 3.1(f)(ii),
which shall be read with the Material Adverse Effect qualification)) both when
made and at and as of the Closing Date, as if made at and as of such time
(except to the extent expressly made as of an earlier date, in which case as of
such date), except where the failure of such representations and warranties to
be so true and correct (without giving effect to any limitation as to

of Wachtell, Lipton, Rosen & Katz ("Thermo Electron's Counsel"), in form and
substance reasonably satisfactory to Thermo Electron, dated the Closing Date, to
the effect that, on the basis of facts, representations and assumptions set
forth or referred to in such opinion that are consistent with the state of facts
existing at the Effective Time, the Merger will be treated as a reorganization
within the meaning of Section 368(a) of the Code. In rendering such opinion,
Thermo Electron's Counsel may require and rely upon representations and
covenants, including those contained in certificates of officers of Thermo
Electron, Fisher and others, reasonably satisfactory in form and substance to
such counsel.

      respect to Thermo Electron shall have been publicly proposed or publicly
      disclosed or, solely in the case of a termination under Section 7.1(c),

      Fee on the business day following such termination;

                   (ii) if either party shall terminate this Agreement pursuant
      to (A) Section 7.1(b)(i) and at the time of such termination the Fisher
      Stockholder Approval has not been obtained, or (B) Section 7.1(b)(iii), or
      Thermo Electron shall terminate this Agreement pursuant to Section 7.1(d),

      within 12 months of the date of such termination of this Agreement, Fisher
      or any of its Subsidiaries executes any definitive agreement with respect
      to, or consummates any Alternative Transaction, then Fisher shall pay the

      being understood that in no event shall Fisher be required to pay the fee
      referred to in this Section 7.2(c) on more than one occasion).

Approval or the Thermo Electron Stockholder

                                      -78-


Approval there may not be, without further approval of the stockholders of
Fisher and Thermo Electron, any amendment of this Agreement that changes the
amount or the form of the consideration to be delivered to the holders of Fisher
Common Stock hereunder, or which by Applicable Laws otherwise expressly requires
the further approval of such stockholders. This Agreement may not be amended
except by an instrument in writing signed on behalf of each of the parties
hereto and duly approved by the parties' respective Boards of Directors or a
duly designated committee thereof.

         SECTION 7.4. Extension; Waiver. At any time prior to the Effective
Time, a party may, subject to the proviso of Section 7.3 (and for this purpose
treating any waiver referred to below as an amendment), (a) extend the time for
the performance of any of the obligations or other acts of the other parties
hereto, (b) waive any inaccuracies in the representations and warranties of the
other parties contained in this Agreement or in any document delivered pursuant
to this Agreement or (c) waive compliance by the other party hereto with any of
the agreements or conditions contained in this Agreement. Any agreement on the
part of a party to any such extension or waiver shall be valid only if set forth
in an instrument in writing signed on behalf of such party. Any extension or
waiver given in compliance with this Section 7.4 or failure to insist on strict
compliance with an obligation, covenant, agreement or condition shall not
operate as a waiver of, or estoppel with respect to, any subsequent or other
failure.

Agreement which by its terms contemplates performance after the Effective Time.

         SECTION 8.5. Interpretation. When a reference is made in this Agreement
to an Article, Section or Exhibit, such reference shall be to an Article or
Section of, or an Exhibit to, this Agreement unless otherwise indicated.
Whenever the words "include," "includes" or "including" are used in this
Agreement, they shall be deemed to be followed by the words "without
limitation." The words "hereof," "herein" and "hereunder" and words of similar
import when used in this Agreement shall refer to this Agreement as a whole and
not to any particular provision of this Agreement. All terms defined in this
Agreement shall have the defined meanings when used in any certificate or other
document made or delivered pursuant hereto unless otherwise defined therein. The
definitions contained in this Agreement are applicable to the singular as well
as the plural forms of such terms and to the masculine as well as to the
feminine and neuter genders of such term. Any agreement, instrument or statute
defined or referred to herein or in any agreement or instrument that is referred
to herein means such agreement, instrument or statute as from time to time
amended, modified or supplemented, including (in the case of agreements or
instruments) by waiver or consent and (in the case of statutes) by succession of
comparable successor statutes and references to all attachments thereto

                                      -86-


and instruments incorporated therein. References to a Person are also to its
permitted successors and assigns.

         SECTION 8.6. Counterparts. This Agreement may be executed in two or
more counterparts, all of which shall be considered one and the same agreement
and shall become effective when one or more counterparts have been signed by
each of the parties and delivered to the other parties.

         SECTION 8.7. Entire Agreement; No Third-Party Beneficiaries. This
Agreement (including the CDA and the documents and instruments referred to
herein) (a) constitutes the entire agreement, and supersedes all prior
agreements and understandings, both written and oral, among the parties with
respect to the subject matter of this Agreement and neither party is relying on
any other oral or written representation, agreement or understanding and (b)
except for the provisions of Section 5.5 (which are intended to benefit the
Indemnified Parties, including Indemnified Parties who or which are not parties
hereto), is not intended to confer upon any Person other than the parties any
rights or remedies.

         SECTION 8.8. Governing Law. This Agreement and any disputes arising out
of or related to this Agreement shall be governed by, and construed in
accordance with, the laws of the State of New York, regardless of the laws that
might otherwise govern under applicable principles of conflict of laws thereof,
except to the extent that the DGCL applies to the Merger or the Delaware General
Corporation Law applies to the Charter Amendment.

         SECTION 8.9. Assignment. Neither this Agreement nor any of the rights,
interests or obligations under this Agreement shall be assigned, in whole or in
part, by operation of law or otherwise by either of the parties hereto without
the prior written consent of the other party. Any assignment in violation of the
preceding sentence shall be void. Subject to the preceding two sentences, this
Agreement will be binding upon, inure to the benefit of, and be enforceable by,
the parties and their respective successors and assigns.

         SECTION 8.10. Consent to Jurisdiction. Each of the parties hereto (a)
consents to submit itself to the personal jurisdiction of any federal court
located in the State of New York or any New York state court in the event any
dispute arises out of this Agreement or any of the transactions contemplated by
this Agreement, (b) agrees that it will not attempt to deny or defeat such
personal jurisdiction by motion or other request for leave from any such court,
and (c) agrees that it will not bring any action relating to this Agreement or
any of the transactions contemplated by this Agreement in any court other than a
federal court sitting in the State of New York or a New York state court.

         SECTION 8.11. Headings, etc. The headings and table of contents
contained in this Agreement are for reference purposes only and shall not affect
in any way the meaning or interpretation of this Agreement.

         SECTION 8.12. Severability. If any term or other provision of this
Agreement is invalid, illegal or incapable of being enforced by any rule of law
or public policy, all other conditions and provisions of this Agreement shall
nevertheless remain in full force and effect, insofar as the foregoing can be
accomplished without materially affecting the economic benefits

                                      -87-


anticipated by the parties to this Agreement. Upon such determination that any
term or other provision is invalid, illegal or incapable of being enforced, the
parties hereto shall negotiate in good faith to modify this Agreement so as to
effect the original intent of the parties as closely as possible to the fullest
extent permitted by Applicable Laws in an acceptable manner to the end that the
transactions contemplated hereby are fulfilled to the extent possible.

         SECTION 8.13. Failure or Indulgence Not Waiver; Remedies Cumulative. No
failure or delay on the part of any party hereto in the exercise of any right
hereunder shall impair such right or be construed to be a waiver of, or
acquiescence in, any breach of any representation, warranty or agreement herein,
nor shall any single or partial exercise of any such right preclude any other or
further exercise thereof or of any other right. All rights and remedies existing
under this Agreement are cumulative to, and not exclusive of, any rights or
remedies otherwise available.

         SECTION 8.14. Waiver of Jury Trial. EACH OF THERMO ELECTRON, MERGER SUB
AND FISHER HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION,
PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE)
ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED
HEREBY OR THE ACTIONS OF THERMO ELECTRON, MERGER SUB OR FISHER IN THE
NEGOTIATION, ADMINISTRATION, PERFORMANCE AND ENFORCEMENT OF THIS AGREEMENT.

         SECTION 8.15. Specific Performance. The parties agree that irreparable
damage would occur and that the parties would not have any adequate remedy at
law in the event that any of the provisions of this Agreement were not performed
in accordance with their specific terms or were otherwise breached. It is
accordingly agreed that the parties shall be entitled to an injunction or
injunctions to prevent breaches of this Agreement and to enforce specifically
the terms and provisions of this Agreement in any federal court located in the
State of New York or in New York state court, this being in addition to any
other remedy to which they are entitled at law or in equity.
