                           THERMO ELECTRON CORPORATION

                          EXECUTIVE SEVERANCE AGREEMENT


THIS  AGREEMENT  by  and  between  THERMO  ELECTRON   CORPORATION,   a  Delaware
corporation  (the "Company"),  and ____________ (the  "Executive") is made as of
November 19, 2003 (the "Effective Date").

     WHEREAS,  the Company recognizes that the uncertainty  regarding the future
employment   prospects  for  key  personnel  may  result  in  the  departure  or
distraction   of  key  personnel  to  the  detriment  of  the  Company  and  its
stockholders; and

     WHEREAS, the Board of Directors of the Company (the "Board") has determined
that appropriate  steps should be taken to reinforce and encourage the continued
employment  and  dedication of the Company's key personnel  without  distraction
from such uncertainty and related events and circumstances;

     NOW, THEREFORE,  as an inducement for and in consideration of the Executive
remaining in its employ, the Company agrees that the Executive shall receive the
severance  benefits  set forth in this  Agreement  in the event the  Executive's
employment  with the Company is  terminated  under the  circumstances  described
below.

     1. Key Definitions.

     As used herein,  the following  terms shall have the  following  respective
meanings:

          1.1 "Change in Control"  means an event or occurrence set forth in any

as amended (the  "Exchange  Act")) (a "Person") of  beneficial  ownership of any
capital  stock  of  the  Company  if,  after  such   acquisition,   such  Person
beneficially  owns  (within  the  meaning  of Rule 13d-3  promulgated  under the
Exchange  Act) 40% or more of either (i) the  then-outstanding  shares of common
stock of the  Company  (the  "Outstanding  Company  Common  Stock")  or (ii) the
combined voting power of the then-outstanding securities of the Company entitled

               (b) such time as the  Continuing  Directors (as defined below) do

Directors of a successor corporation to the Company), where the term "Continuing
Director"  means at any date a member  of the  Board (i) who was a member of the

               (c) the consummation of a merger, consolidation,  reorganization,
recapitalization  or statutory share exchange involving the Company or a sale or
other  disposition of all or  substantially  all of the assets of the Company in

following  such Business  Combination,  each of the following two  conditions is
satisfied: (i) all or substantially all of the individuals and entities who were
the beneficial  owners of the  Outstanding  Company Common Stock and Outstanding
Company  Voting  Securities  immediately  prior  to  such  Business  Combination
beneficially own, directly or indirectly,  more than 60% of the then-outstanding
shares of common  stock and the combined  voting  power of the  then-outstanding
securities   entitled  to  vote   generally  in  the   election  of   directors,
respectively,  of the  resulting  or  acquiring  corporation  in  such  Business
Combination (which shall include,  without limitation,  a corporation which as a
result  of  such  transaction  owns  the  Company  or  substantially  all of the
Company's  assets  either  directly or through one or more  subsidiaries)  (such
resulting  or  acquiring  corporation  is referred  to herein as the  "Acquiring
Corporation")  in  substantially   the  same  proportions  as  their  ownership,
immediately  prior to such  Business  Combination,  of the  Outstanding  Company
Common Stock and Outstanding Company Voting Securities,  respectively;  and (ii)
no Person (excluding the Acquiring  Corporation or any employee benefit plan (or
related  trust)  maintained  or  sponsored  by the  Company or by the  Acquiring
Corporation) beneficially owns, directly or indirectly,  40% or more of the then
outstanding  shares  of common  stock of the  Acquiring  Corporation,  or of the
combined  voting power of the  then-outstanding  securities of such  corporation
entitled to vote generally in the election of directors; or

               (d)  approval  by the  stockholders  of the Company of a complete
liquidation or dissolution of the Company.

          1.2  "Cause"  means the  Executive's  willful  engagement  in  illegal
conduct or gross misconduct  which is materially and  demonstrably  injurious to
the  Company.  For purposes of this Section 1.2, no act or failure to act by the
Executive  shall be  considered  "willful"  unless it is done,  or omitted to be
done, in bad faith and without
<PAGE>

                                                                     Page 3 of 7

reasonable  belief  that the  Executive's  action  or  omission  was in the best
interests of the Company.

          1.3 "Disability" means the Executive's inability, due to a physical or
mental disability,  for a period of 90 days, whether or not consecutive,  during
any 360-day period to perform the  Executive's  duties on behalf of the Company,
with or without reasonable  accommodation as that term is defined under state or
federal  law.  A  determination  of  disability  shall  be made  by a  physician
satisfactory  to both  the  Executive  and  the  Company,  provided  that if the
Executive  and the Company do not agree on a physician,  the  Executive  and the
Company  shall each select a physician  and these two  together  shall  select a
third  physician,  whose  determination as to disability shall be binding on all
parties.

     2. Term of Agreement. This Agreement, and all rights and obligations of the
parties  hereunder,  shall take effect upon the Effective  Date and shall expire
upon the first to occur of (a) the  expiration of the Term (as defined below) or
(b) the  fulfillment by the Company of all of its  obligations  under Sections 4
and 5.2 if the Executive's  employment with the Company  terminates prior to the
expiration  of the Term.  "Term"  shall  mean the  period  commencing  as of the
Effective  Date and continuing in effect  through  December 31, 2008;  provided,
however,  that on January 1, 2009 and each January 1 thereafter,  the Term shall
be  automatically  extended for one additional  year unless,  not later than six
months prior to the scheduled  expiration of the Term  (including any extension)
thereof, the Company shall have given the Executive written notice that the Term
will not be extended.

     3.  Not an  Employment  Contract.  The  Executive  acknowledges  that  this
Agreement  does not constitute a contract of employment or impose on the Company
any  obligation to retain the  Executive as an employee and that this  Agreement
does not prevent the Executive from terminating employment at any time.

     4. Benefits to Executive.

          4.1 Compensation.

               (a) Termination Without Cause. If the Executive's employment with
the Company is  terminated by the Company  (other than for Cause,  Disability or
death) then the Executive shall be entitled to the following benefits:

                    (i) the Company  shall pay to the Executive in a lump sum in
cash within 30 days after the date of termination the aggregate of the following
amounts:

                         (1) the sum of (A) one and  one-half  (1.5)  times  the
Executive's  annual  base salary as in effect  immediately  prior to the date of
termination,  and (B) the amount of any accrued  vacation pay, to the extent not
previously paid; and
<PAGE>
                                                                     Page 4 of 7

                    (ii) for 18 months  after the date of  termination,  or such
longer period as may be provided by the terms of the appropriate plan,  program,
practice or policy,  the Company shall continue to provide  medical,  dental and
life  insurance  benefits to the Executive and the  Executive's  family at least
equal to  those  which  would  have  been  provided  to them if the  Executive's
employment had not been  terminated,  in accordance with the applicable  benefit
plans  in  effect  on the  date of  termination  or,  if more  favorable  to the
Executive and the Executive's family, in effect generally at any time thereafter
with  respect  to  other  peer  executives  of the  Company  and its  affiliated
companies;  provided,  however,  that (A) if the terms of a benefit  plan do not
permit continued  participation therein by a former employee,  then an equitable
arrangement  shall be made by the Company (such as a substitute  or  alternative
plan) to provide as substantially equivalent a benefit as is reasonably possible
and  (B) if the  Executive  becomes  reemployed  with  another  employer  and is
eligible to receive a  particular  type of  benefits  (e.g.,  medical  insurance
benefits) from such employer on terms at least as favorable to the Executive and
the Executive's family as those being provided by the Company,  then the Company
shall no  longer  be  required  to  provide  those  particular  benefits  to the
Executive and the Executive's family; and

                    (iii) to the extent not  previously  paid or  provided,  the
Company  shall  timely  pay or  provide to the  Executive  any other  amounts or
benefits  required to be paid or provided or which the  Executive is eligible to
receive  following the  Executive's  termination  of employment  under any plan,
program,  policy,  practice,  contract  or  agreement  of the  Company  and  its
affiliated  companies  (other than severance  benefits)  (such other amounts and
benefits shall be hereinafter referred to as the "Other Benefits").

               (b)  Termination  for Cause,  Disability or Death. If the Company
terminates  the   Executive's   employment  with  the  Company  because  of  the
Executive's  disability,  the Executive's  death or for Cause,  then the Company
shall (i) pay the  Executive or the  Executive's  estate,  in a lump sum in cash
within 30 days  after  the date of  termination,  the  Executive's  base  salary
through the date of termination  and (ii) timely pay or provide to the Executive
the Other Benefits.

          4.2 Outplacement Services. In the event the Executive is terminated by
the  Company  (other than for Cause,  Disability  or death),  the Company  shall
provide  outplacement  services  through  one  or  more  outside  firms  of  the
Executive's choosing up to an aggregate of $20,000, with such services to extend
until the earlier of (i) 12 months  following the termination of the Executive's
employment or (ii) the date the Executive secures full time employment.

          4.3  Mitigation.  The Executive  shall not be required to mitigate the
amount of any  payment or  benefits  provided  for in this  Section 4 by seeking
other  employment  or  otherwise.   Further,   except  as  provided  in  Section
4.1(a)(ii), the amount of any payment or benefits provided for in this Section 4
shall not be reduced by any compensation  earned by the Executive as a result of
employment by another employer,

by retirement  benefits,  by offset against any amount claimed to be owed by the
Executive to the Company or otherwise.

          4.4.  Release  of  Claims by  Executive.  The  Executive  shall not be
entitled  to any  payments  or other  benefits  hereunder  unless the  Executive
executes and, if  applicable,  does not revoke,  a full and complete  release of
claims and separation agreement, in the form to be provided by the Company.

     5. Disputes.  All claims by the Executive for benefits under this Agreement
shall be directed to and  determined  by the Board and shall be in writing.  Any
denial  by the Board of a claim  for  benefits  under  this  Agreement  shall be
delivered to the  Executive in writing and shall set forth the specific  reasons
for the denial. The Board shall afford a reasonable opportunity to the Executive
for a review of the decision denying a claim. Any further dispute or controversy
arising under or in connection with this Agreement shall be settled  exclusively
by arbitration  in Boston,  Massachusetts,  in accordance  with the rules of the
American Arbitration  Association then in effect. Judgment may be entered on the
arbitrator's award in any court having jurisdiction.

     6. Successors.

          6.1  Successor to Company.  The Company  shall  require any  successor
(whether direct or indirect, by purchase, merger, consolidation or otherwise) to
all or substantially  all of the business or assets of the Company  expressly to
assume and agree to perform  this  Agreement to the same extent that the Company
would be required to perform it if no such  succession had taken place.  As used
in this  Agreement,  "Company"  shall mean the Company as defined  above and any
successor  to its business or assets as  aforesaid  which  assumes and agrees to
perform this Agreement, by operation of law or otherwise.

          6.2 Successor to Executive.  This Agreement shall inure to the benefit
of and be  enforceable  by the  Executive's  personal or legal  representatives,
executors,   administrators,   successors,  heirs,  distributees,  devisees  and
legatees. If the Executive should die while any amount would still be payable to
the Executive or the Executive's family hereunder if the Executive had continued
to live, all such amounts,  unless otherwise  provided herein,  shall be paid in
accordance  with  the  terms  of  this  Agreement  to  the  executors,  personal
representatives or administrators of the Executive's estate.

     7.  Notice.  All  notices,  instructions  and  other  communications  given
hereunder  or in  connection  herewith  shall be in  writing.  Any such  notice,
instruction or communication shall be sent either (i) by registered or certified
mail, return receipt requested, postage prepaid, or (ii) prepaid via a reputable
nationwide  overnight courier service, in each case addressed to the Company, at
81 Wyman Street, Waltham,  Massachusetts and to the Executive at the Executive's
principal  residence as currently reflected on the Company's records (or to such
other address as either the Company or the  Executive may have  furnished to the
other in  writing in  accordance  herewith).  Any such  notice,  instruction  or
communication shall be deemed to have been delivered five

business days after it is sent by registered or certified  mail,  return receipt
requested, postage prepaid, or one business day after it is sent via a reputable
nationwide  overnight  courier  service.  Either  party  may  give  any  notice,
instruction or other communication  hereunder using any other means, but no such
notice,  instruction  or other  communication  shall be deemed to have been duly
delivered  unless and until it  actually is received by the party for whom it is
intended.

     8. Miscellaneous.

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

          8.2 Injunctive  Relief.  The Company and the Executive  agree that any
breach of this  Agreement  by the  Company  is  likely  to cause  the  Executive
substantial  and  irrevocable  damage  and  therefore,  in the event of any such
breach, in addition to such other remedies which may be available, the Executive
shall have the right to specific performance and injunctive relief.

          8.3 Governing  Law. The  validity,  interpretation,  construction  and
performance  of this  Agreement  shall be governed by the  internal  laws of the
Commonwealth of Massachusetts, without regard to conflicts of law principles.

          8.4 Waivers.  No waiver by the Executive at any time of any breach of,
or  compliance  with,  any  provision  of this  Agreement to be performed by the
Company  shall  be  deemed  a  waiver  of that  or any  other  provision  at any
subsequent time.

          8.5 Counterparts. This Agreement may be executed in counterparts, each
of which  shall be deemed to be an  original  but both of which  together  shall
constitute one and the same instrument.

          8.6 Tax Withholding. Any payments provided for hereunder shall be paid
net of any applicable  tax  withholding  required under federal,  state or local
law.

          8.7 Entire  Agreement.  This Agreement sets forth the entire agreement
of the parties  hereto in respect of the  subject  matter  contained  herein and
supersedes   all   prior   agreements,   promises,   covenants,    arrangements,
communications,  representations or warranties,  whether oral or written, by any
officer,  employee  or  representative  of any party  hereto in  respect  of the
subject matter contained  herein,  and any prior agreement of the parties hereto
in respect of the  subject  matter  contained  herein is hereby  terminated  and
cancelled,  except  as  provided  in  the  next  sentence.  Notwithstanding  the
foregoing  sentence,  if the Executive is party to an agreement with the Company
providing  for the  payment of benefits in the event  employment  is  terminated
after a Change in Control (a "Change  in  Control  Agreement"),  such  Change in
Control  Agreement  shall not be terminated  or cancelled by this  Agreement and
such  Change  in  Control  Agreement  shall  survive  and  remain  in  effect in
accordance  with its own terms.  In the event the  Executive

                                                                     Page 7 of 7

actually receives benefits under the Change in Control Agreement,  the Executive
shall not also be entitled to receive benefits under this Agreement.

          8.8  Amendments.  This  Agreement may be amended or modified only by a
written instrument executed by both the Company and the Executive.

     IN WITNESS  WHEREOF,  the parties hereto have executed this Agreement under
seal as of the day and year first set forth above.
