          (b)  Except as specifically otherwise provided in the Ancillary
Agreements, Viasys shall indemnify, defend and hold harmless the Thermo Electron
Indemnitees from and against (1) all Indemnifiable Losses arising from or
relating to the Viasys Business, whether such Indemnifiable Losses relate to
events, occurrences or circumstances occurring or existing, or whether such
Indemnifiable Losses are asserted, before or after the Distribution Date; (2)
all Indemnifiable Losses incurred by Thermo Electron as a consequence of any
misstatement or omission of a material fact with respect to Viasys based on
information supplied by Viasys in any documents or filings prepared for purposes
of compliance or qualification under applicable securities laws in connection
with the Distribution and related transactions, including without limitation,
the Information Statement and the Form 10; (3) all Indemnifiable Losses arising
from any breach of or failure to perform any obligation on the part of any
member of the Viasys Group contained in this Agreement or any of the Ancillary
Agreements; and (4) all Indemnifiable Losses arising from or relating to any
obligations of any member of the Thermo Electron Group or its Representatives
under any TMO Letter of Credit Guarantees.

          (c)  If any Indemnifiable Loss arises from or relates to both the
Thermo Electron Business and the Viasys Business, Thermo Electron shall
indemnify the Viasys Indemnitees against any portion of such Indemnifiable Loss
that pertains more directly to the Thermo Electron Business than to the Viasys
Business, and Viasys shall indemnify the Thermo Electron Indemnitees against any
portion of such Indemnifiable Loss that pertains more directly to the Viasys
Business than to the Thermo Electron Business.

          (d)  Notwithstanding anything to the contrary set forth herein,
indemnification relating to any arrangements between any member of the Thermo
Electron Group and any member of the Viasys Group (or any unit of the Viasys
Business) for the provision after the Distribution of goods and services shall
be governed by the terms of such arrangements and not by this Section.

     5.3  PROCEDURES FOR INDEMNIFICATION FOR THIRD-PARTY CLAIMS.

          (a)  Viasys shall, and shall cause the other Viasys Indemnitees to,
notify Thermo Electron in writing promptly after learning of any Third-Party
Claim for which any Viasys Indemnitee intends to seek indemnification from
Thermo Electron under this Agreement. Thermo Electron shall, and shall cause the
other Thermo Electron Indemnitees to, notify Viasys in writing promptly after
learning of any Third-Party Claim for which any Thermo Electron

                                       8
<PAGE>

Indemnitee intends to seek indemnification from Viasys under this Agreement. The
failure of any Indemnitee to give such notice shall not relieve any Indemnifying
Party of its obligations under this Article V except to the extent that such
Indemnifying Party or its Affiliate is actually prejudiced by such failure to
give notice. Such notice shall describe such Third-Party Claim in reasonable
detail considering the information provided to the Indemnitee.

          (b)  Except as otherwise provided in subsection (c) of this Section
5.3, an Indemnifying Party may, by notice to the Indemnitee and to Viasys, if
Thermo Electron is the Indemnifying Party, or to Thermo Electron, if Viasys is
the Indemnifying Party, at any time after receipt by such Indemnifying Party of
such Indemnitee's notice of a Third-Party Claim, undertake (itself or through
another member of its Group) the defense or settlement of such Third-Party
Claim. If an Indemnifying Party undertakes the defense of any Third-Party Claim,
such Indemnifying Party shall thereby admit its obligation to indemnify the
Indemnitee against such Third-Party Claim, and such Indemnifying Party shall
control the investigation and defense or settlement thereof, except that such
Indemnifying Party shall not require any Indemnitee, without its prior written
consent, to take or refrain from taking any action in connection with such
Third-Party Claim, or make any public statement, which such Indemnitee
reasonably considers to be against its interest, nor shall the Indemnifying
Party, without the prior written consent of the Indemnitee and of Viasys, if the
Indemnitee is a Viasys Indemnitee, or of Thermo Electron, if the Indemnitee is a
Thermo Electron Indemnitee, consent to any settlement that does not include as a
part thereof an unconditional release of the Indemnitees from liability with
respect to such Third-Party Claim or that requires the Indemnitee or any of its
Representatives or Affiliates to make any payment that is not fully indemnified
under this Agreement or to submit to any non-monetary remedy; and subject to the
Indemnifying Party's control rights, as specified herein, the Indemnitees may
participate in such investigation and defense, at their own expense.

          (c)  With respect to any Third-Party Claim, if there is a material
conflict of interest between the Indemnifying Party and the Indemnitees
involved, neither the Indemnifying Party nor the Indemnitees shall be entitled
to control the defense or settlement thereof. If an Indemnitee notifies an
Indemnifying Party of a Third-Party Claim pursuant to this Section 5.3, and the
Indemnifying Party does not take control of the defense or settlement thereof,
or prior to the time that it does so take control, neither the Indemnifying
Party nor the Indemnitees shall be entitled to control the defense or settlement
thereof. In any such event, the Indemnifying Parties and the Indemnitees
involved shall each be entitled to conduct their own investigation and defense,
but the parties shall cooperate to conduct such investigation and defense as
efficiently as possible. No Indemnitee may compromise or settle any Third-Party
Claim described in this subsection as to which indemnification from an
Indemnifying Party has or will be sought under this Agreement without the prior
written consent of such Indemnifying Party.

          (d)  If an Indemnifying Party is required to indemnify any Indemnitees
with respect to a Third-Party Claim described in subsection (c) of this Section
5.3, such Indemnifying Party shall pay the reasonable attorneys' fees and
expenses of one law firm representing the Indemnitees involved in each
jurisdiction with respect thereto.

          (e)  Viasys shall, and shall cause the other Viasys Indemnitees to,
and Thermo Electron shall, and shall cause the other Thermo Electron Indemnitees
to, make available to each other, their counsel and other Representatives, all
information and documents reasonably

                                       9
<PAGE>

available to them which relate to any Third-Party Claim, and otherwise cooperate
as may reasonably be required in connection with the investigation, defense and
settlement thereof.

     5.4  REMEDIES CUMULATIVE. The remedies provided in this Article V shall be
cumulative and shall not preclude assertion by any Indemnitee of any other
rights or the seeking of any other remedies against any Indemnifying Party.
However, the procedures set forth in Section 5.3 shall be the exclusive
procedures governing any indemnity action brought under this Agreement or
otherwise and relating to a Third-Party Claim, except as otherwise specifically
provided in any of the Ancillary Agreements.

     5.5  RELEASE OF PRE-DISTRIBUTION CLAIMS.

          (a)  Except as provided in Section 5.5(c), effective as of the

conditions existing or alleged to have existed on or before the Distribution
Date, including in connection with the transactions and all other activities to
implement the Distribution and the transfer of the Viasys Assets to the Viasys
Group and the assumption by the Viasys Group of the Viasys Liabilities.

          (c)  Nothing contained in Section 5.5(a) or (b) shall impair any right
of any Person to enforce this Agreement or the Ancillary Agreements, or any
agreements, arrangements, commitments or understandings that are referred to
herein or therein as not terminating as of the Distribution Date, in each case
in accordance with its terms. Without limiting the foregoing, nothing contained
in Section 5.5(a) or (b) shall release any Person from:

                                       10
<PAGE>

               (i)  any Liability provided in or resulting from any agreement
among any members of the Thermo Electron Group or the Viasys Group that is
specified in Section 9.4(b) or in Schedule 9.4(b) as not to terminate as of the
Distribution Date;

               (ii) any Liability, contingent or otherwise, assumed,
transferred, assigned or allocated to the Group of which such Person is a member
in accordance with, or any other Liability of any member of any Group under,
this Agreement or any Ancillary Agreement;

               (iii) any Liability that the parties may have with respect to
indemnification or contribution pursuant to this Agreement or any Ancillary
Agreement, which Liability shall be governed by the provisions of this Article
V, or, if applicable, by the appropriate provisions of the Ancillary Agreements;
or

               (iv) any Liability the release of which would result in the
release of any Person other than a Person released pursuant to Section 5.5(a) or
(b).

          (d)  Viasys shall not make, and shall not permit any member of the
Viasys Group to make, any claim or demand, or commence any Action asserting any
claim or demand, including any claim of contribution or any indemnification,
against Thermo Electron, any member of the Thermo Electron Group, or any other
Person released pursuant to Section 5.5(a), with respect to any Liabilities
released pursuant to Section 5.5(a). Thermo Electron shall not make, and shall
not permit any member of the Thermo Electron Group, to make any claim or demand,
or commence any Action asserting any claim or demand, including any claim of
contribution or any indemnification, against Viasys or any member of the Viasys
Group, or any other Person released pursuant to Section 5.5(b), with respect to
any Liabilities released pursuant to Section 5.5(b).

          (e)  It is the intent of each of Thermo Electron and Viasys by virtue
of the provisions of this Section 5.5 to provide for a full and complete release
and discharge of all Liabilities existing or arising from all acts and events
occurring or failing to occur or alleged to have occurred or to have failed to
occur and all conditions existing or alleged to have existed on or before the
Distribution Date, between or among Viasys or any member of the Viasys Group, on
the one hand, and Thermo Electron or any member of the Thermo Electron Group, on
the other hand (including any contractual agreements or arrangements existing or
alleged to exist between or among any such members on or before the Distribution
Date), except as expressly set forth in Section 5.5(c). At any time, at the
request and expense of any other party, each party shall cause each member of
its respective Group to execute and deliver releases reflecting the provisions
hereof.

Distribution is intended to qualify under Section 355 of the Code, and that the
characterization of the transactions contemplated hereunder for tax purposes and
the liability of the parties for taxes shall be governed by the Tax Matters
Agreement. Except as otherwise specifically provided herein or as agreed between
the parties from time to time, Thermo Electron and Viasys shall bear their own
expenses associated with the Distribution.

after the Distribution Date, Thermo Electron shall deliver to Viasys all
existing corporate records in the possession of Thermo Electron relating to

relating to the Viasys Business, except (a) to the extent such items are already

<PAGE>

expiration of the Transition Services Agreement). Such records shall be the
property of Viasys but shall be available to Thermo Electron for review and
duplication until Thermo Electron shall notify Viasys in writing that such
records are no longer of use to Thermo Electron.

     8.2  ACCESS TO INFORMATION. From and after the Distribution Date, Thermo
Electron shall, and shall cause each of the other members of the Thermo Electron

information (collectively, "Information") within the Thermo Electron Group's
possession relating to the business of the Viasys Group, insofar as such access
is reasonably required by any member of the Viasys Group. Viasys shall, and
shall cause each of the other members of the Viasys Group to, afford to the
members of the Thermo Electron Group and their authorized accountants, counsel
and other designated representatives reasonable access (including using
reasonable efforts to give access to persons or firms possessing Information)
and duplicating rights during normal business hours to Information within the
Viasys Group's possession relating to the business of the Thermo Electron Group
as constituted after the Distribution, insofar as such access is reasonably
required by any member of the Thermo Electron Group. Information may be
requested under this Article VIII for, without limitation, audit, accounting,
claims, litigation and tax purposes, as well as for purposes of fulfilling
disclosure and reporting obligations and for performing the transactions
contemplated in this Agreement and the Ancillary Agreements.

     8.3  PRODUCTION OF WITNESSES. At all times from and after the Distribution
Date, each of Thermo Electron and Viasys shall, and shall cause the other
members of its respective Group to, use reasonable efforts to make available to
the members of the other Group, upon written request, its officers, directors,

be required in connection with legal, administrative or other proceedings in
which the requesting party may from time to time be involved and relating to the

relating to or in connection with the relationship between any member of the
Thermo Electron Group and any member of the Viasys Group on or prior to the

     8.4  REIMBURSEMENT. Except to the extent otherwise contemplated by any

incurred in providing such Information.

Distribution Date, each of Thermo Electron and Viasys shall retain all
Information relating to the other, except as otherwise required by law or set
forth in an Ancillary Agreement or except to the extent that such Information is
in the public domain or in the possession of the other party; provided, that,
after the expiration of such retention period, such Information shall not be
destroyed or otherwise disposed of at any time, unless, prior to such
destruction or disposal, (i) the party proposing to destroy or otherwise dispose
of such Information shall provide no less than 90 days' prior written notice to
the other, specifying in reasonable detail the Information

                                       14
<PAGE>

proposed to be destroyed or disposed of and (ii) if a recipient of such notice
shall request in writing prior to the scheduled date for such destruction or
disposal that any of the Information proposed to be destroyed or disposed of be
delivered to such requesting party, the party proposing the destruction or
disposal shall promptly arrange for the delivery of such of the Information as
was requested, at the expense of the party requesting such Information.

     8.6  CONFIDENTIALITY. Subject to any contrary requirement of law and the
right of each party to enforce its rights hereunder in any legal action, each
party shall keep strictly confidential, and shall use its reasonable efforts to
cause its Affiliates and Representatives to keep strictly confidential, any
Information of or concerning the other party which it or any of its Affiliates
or Representatives may acquire pursuant to, or in the course of performing its
obligations under, any provisions of this Agreement or any Ancillary Agreement;
provided, however, that such obligation to maintain confidentiality shall not
apply to Information which: (i) at the time of disclosure was in the public
domain, not as a result of improper acts by the receiving party; (ii) is
received by the receiving party from a third party who did not receive such
Information from the disclosing party under an obligation of confidentiality; or
(iii) is compelled to be disclosed by judicial or administrative process or, in
the opinion of such Person's counsel, by other requirements of law.
Notwithstanding the foregoing, each of Thermo Electron and Viasys shall be
deemed to have satisfied its obligations under this Section 8.6 with respect to
any Information if it exercises the same care with regard to such Information as
it takes to preserve the confidentiality of its own similar Information.

limitation, on any signs, letterhead, business cards, invoices and other
business forms, telephone directory listings and promotional materials.

          (c)  During the 180-day period set forth in Section 9.3(b), Viasys
shall maintain the same standards of quality for products and services provided
under the Thermo Electron Trademarks as previously provided by Thermo Electron
and its Subsidiaries. During such period, Thermo Electron shall have the right
to monitor Viasys's use of the Thermo Electron Trademarks and shall be able to
control the quality of any Viasys products and/or services that bear the Thermo
Electron Trademarks.

     9.4  TERMINATION OF INTERCOMPANY AGREEMENTS.

          (a)  Viasys and each member of the Viasys Group, on the one hand, and
Thermo Electron and each member of the Thermo Electron Group, on the other hand,
hereby terminate any and all agreements, arrangements, commitments or
understandings, whether or not in writing, between or among Viasys and/or any

termination) shall be of any further force or effect after the Distribution
Date. Each Party shall, at the reasonable request of any other party, take, or
cause to be taken, such other actions as may be necessary to effect the
foregoing.

          (b)  The provisions of Section 9.4(a) shall not apply to any of the

any of the members of their respective Groups); (ii) any agreements,
arrangements, commitments or understandings listed or described on SCHEDULE

of Thermo Electron Common Stock (Current "TMO Options") held immediately prior
to the Distribution Date by Active Employees of the Viasys Group shall be
assumed by Viasys and shall be adjusted as follows: (i) each such Current TMO
Option shall be exercisable, on the same terms and conditions as were applicable
under such Current TMO Option (including those relating to vesting and
expiration of such Current TMO Option) on the Distribution Date, under the
Viasys Equity Incentive Plan to purchase such number of shares of Viasys Common
Stock as is equal to the

                                       16
<PAGE>

number of shares of Thermo Electron Common Stock covered by such Current TMO
Option immediately prior to the Distribution Date multiplied by the Viasys
Exchange Ratio (rounded down to the nearest whole share), and (ii) the exercise
price per share under such Current TMO Option shall equal the exercise price per
share of Thermo Electron Common Stock purchasable pursuant to such Current TMO
Option immediately prior to the Distribution Date divided by the Viasys Exchange
Ratio, with such quotient then rounded down to the nearest whole cent. As soon
as practicable after the Distribution Date, Viasys shall deliver to each Active
Employee of the Viasys Group appropriate notice setting forth the adjustments
made to his or her Current TMO Options pursuant to this Section 9.6. Each of
Thermo Electron and Viasys agrees to take all corporate action necessary to
effectuate and carry out the intent and purposes of this Section 9.6.

     9.7  TREATMENT OF RESTRICTED STOCK. Pursuant to arrangements agreed upon

          (a)  GENERAL. In the event that any dispute should arise between the

the Ancillary Agreements or the interpretation of this Agreement or any of the
Ancillary Agreements, the parties hereto shall resolve such dispute in
accordance with the procedures set forth in this Section 11.11.

          (b)  ARBITRATION.

               (i)  Any party hereto may submit any matter referred to in
Section 11.11(a) to arbitration by notifying the other party, in writing, of
such dispute. Within 30 days after receipt of such notice, the parties shall
designate in writing one arbitrator to resolve the dispute; PROVIDED, that if
the parties cannot agree on an arbitrator within such 30-day period, the
arbitrator shall be selected by the Boston, Massachusetts, Office of the
American Arbitration Association. The arbitrator shall be a retired federal or
state judge, and shall not be an Affiliate, Representative, employee,
consultant, officer, director or stockholder of any party hereto. If neither the
parties nor the Boston, Massachusetts, Office of the American Arbitration
Association is able to identify an individual to serve as the arbitrator, the
Boston, Massachusetts, Office of the American Arbitration Association shall
select an arbitrator from the CPC Panel of Distinguished Neutrals of the CPR
Institute for Dispute Resolution.

               (ii) Within 30 days after the designation of the arbitrator, the
arbitrator and the parties hereto shall meet, at which time the parties shall be
required to set forth in writing all disputed issues and a proposed ruling on
the merits of each such issue.

               (iii) The arbitrator shall set a date for a hearing, which shall
be no later than 45 days after the submission of written proposals pursuant to
Section 11.11(b)(ii), to discuss each of the issues identified by the parties.
Each party hereto shall have the right to be represented by counsel. Except as

Rules of the American Arbitration Association; PROVIDED, HOWEVER, that the
Federal Rules of Evidence shall apply with regard to the admissibility of
evidence and the arbitration shall be conducted by a single arbitrator.

               (iv) The arbitrator shall use his or her reasonable efforts to
rule on each disputed issue within 30 days after the completion of the hearings
described in Section 11.11(b)(iii). The determination of the arbitrator as to
the resolution of any dispute shall be binding and conclusive upon all parties
hereto. All rulings of the arbitrator shall be in writing and shall be delivered
to the parties.

               (v)  The attorneys' fees of the parties hereto in any
arbitration, the fees of the arbitrator, and the costs and expenses of the
arbitration shall be borne by the parties as determined by the arbitrator.

               (vi) Any arbitration pursuant to this Section 11.11 shall be
conducted in Boston, Massachusetts. Any arbitration award may be entered in and
enforced by any court having jurisdiction thereover and shall be final and
binding upon the parties hereto.

               (vii) Notwithstanding the foregoing, nothing in this Section
11.11 shall be construed as limiting in any way the right of a party hereto to
seek a temporary restraining order or other injunctive relief with respect to
any actual or threatened breach of this Agreement or any Ancillary Agreement
from a court of competent jurisdiction. Should any party to this Agreement seek
a temporary restraining order or other injunctive relief, then for purposes of
determining whether to grant such temporary restraining order or other
injunctive relief, the dispute underlying the request for such temporary
restraining order or other injunctive relief may be heard by such court of
competent jurisdiction.

     11.12 EXPENSES. Except as otherwise specifically provided in this Agreement
and the Ancillary Agreements, Thermo Electron and Viasys shall each bear their
own costs and expenses incurred in connection with the transactions contemplated
hereby and by the Ancillary Agreements (including the fees and expenses of the
Agent and of all counsel, accountants and financial and other advisors).

     11.13 FORCE MAJEURE. Neither party shall be considered in default in
performance of its obligations under this Agreement to the extent that its
performance of such obligations is prevented or delayed by any cause beyond its
reasonable control, including but not limited to strikes, labor disputes, civil
disturbances, rebellion, invasion, epidemic, hostilities, war, embargo, natural
disaster, acts of God, fire, sabotage, loss and destruction of property, changes
in laws, regulations or orders, other events or situations which the party was
unable to prevent or overcome despite the exercise of due diligence.

     Without limiting the foregoing, Thermo Electron and Viasys hereby agree
that: (a) Thermo Electron shall pay all expenses directly relating to the
distribution of its Viasys Common Stock as a dividend to Thermo Electron's
stockholders, including but not limited to expenses of the Agent in connection
with the Distribution, all expenses of any advisors retained by Thermo Electron

presentation of the "road show" relating to the Distribution and the

Viasys shall pay all expenses relating to the listing and trading of Viasys
Common Stock on any stock exchange, rights plan and other corporate actions
effected in connection with the Distribution, including but not limited to
expenses of any advisors retained by Viasys in connection with coverage of the
Viasys Common Stock.

law.
