                  2.3.     OTHER THERMO ELECTRON ACTIVITIES. Viasys recognizes
that the Thermo Electron Group now renders and may continue to render management

Group shall be free to render such advice and other services, and Viasys hereby
consents thereto. The Thermo Electron Group shall not be required to devote full
time and attention to the performance of its duties under this Agreement, but
shall devote only so much of its time and attention as it deems reasonable or
necessary to perform the services required hereunder.

         3.       ACCESS TO VIASYS'S INFORMATION. Viasys shall, and shall cause
the other members of the Viasys Group to, make available on a timely basis to
the Thermo Electron Group and its Representatives all information and materials
reasonably requested by Thermo Electron after the Distribution Date to enable it
and/or other members of the Thermo Electron Group to provide the services
hereunder. The Viasys Group shall afford to the Thermo Electron Group and its
Representatives reasonable access, during normal business hours and at such
other times as are reasonably required, to the Viasys Group premises for the
purpose of providing the services hereunder if such services are to be provided
at a facility not owned or operated by the Thermo Electron Group. It is
anticipated, however, that the services to be provided hereunder shall be
performed at Thermo Electron's facilities and that Thermo Electron or any member
of the Thermo Electron Group shall not be obligated to be resident at Viasys's
facilities unless mutually agreed between the parties hereto.

         4.       FEES; EXPENSES; PAYMENT.

                  4.1.     ROUTINE SERVICES. For performing Routine Services,
Thermo Electron will charge Viasys a quarterly fixed fee for any fiscal quarter
(or portion thereof) in which services are performed equal to 0.6% of the
consolidated revenues of Viasys for the fiscal quarter ending December 30,



                                       3

<PAGE>   4
2001, 0.4% of the consolidated revenues of Viasys for the fiscal quarter ending
March 30, 2002, and 0.2% of the consolidated revenues of Viasys for the fiscal
quarter ending June 29, 2002 (such amount to be prorated on a daily basis for
any partial fiscal quarter).

                  4.2.     EXTRAORDINARY SERVICES. For performing Extraordinary
Services, Thermo Electron will charge Viasys a fee equal to the fair market
value of such services, as determined by Thermo Electron in good faith and on a
basis consistent with the fees charged by Thermo Electron to the Viasys Group
and Thermo Electron's publicly-held subsidiaries for such services during the
Base Period.

                  4.3.     THIRD PARTY EXPENSES. In addition to the fees for
Routine Services and Extraordinary Services provided above, Viasys shall pay the
costs of all services provided by outside providers to or for the benefit of the
Viasys Group, as well as all out-of-pocket costs incurred in connection with the
provision of such services. If any member of the Viasys Group is billed by the
provider directly, Viasys shall pay the bill directly. If any member of the
Thermo Electron Group is billed for such services, Thermo Electron may pay the
bill and charge Viasys the amount of the bill or forward the bill to Viasys for
payment by Viasys.

                  4.4.     MANNER OF PAYMENT. The charges for services pursuant
to this Section 4 will be determined and payable no less frequently than on a
quarterly basis. The charges will be due when billed and shall be paid no later
than 30 days from the date of billing. Overdue amounts will bear interest at ten
percent (10%) per annum, compounded monthly. No member of the Viasys Group shall
have any right of set off with respect to amounts to be paid pursuant to this
Agreement nor may it withhold payment during the pendency of any dispute with
respect to amounts to be paid to any member of the Thermo Electron Group
pursuant to this Agreement.

         5.       TAXES. Any taxes assessed on the provision of the services
hereunder shall be paid by Viasys to the extent such taxes are customarily borne
or passed through to the recipient of such services.

         6.       TERM OF AGREEMENT. The term of this Agreement shall commence
on the Distribution Date and shall continue until June 30, 2002.

         7.       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 the other members of its respective Group and the
Representatives to keep strictly confidential, any Information of or concerning
the other party or the other party's Group which it may acquire pursuant to, or
in the course of performing its obligations under, this Agreement; provided,
however, that such obligation to maintain confidentiality shall not apply to
Information that: (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
party'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 7 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.

         8.       INDEMNIFICATION. Viasys hereby agrees to indemnify, defend and
hold harmless each of the Thermo Electron Indemnitees from and against any and
all Indemnifiable Losses resulting from or in connection with third party claims
arising from the Thermo Electron Group's performance of the services hereunder,
unless such third party claims are due to Thermo Electron's gross negligence or
willful misconduct in performing the services hereunder. In defending against
the claim, Viasys shall have the right to employ counsel of its choosing and
shall at all times have the power to direct the defense against the claim.
Thermo Electron shall provide such assistance and cooperation, at Viasys's cost,
as Viasys may reasonably request in connection with the defense of any claim
with respect to which indemnity may be sought against Viasys pursuant to this
Section 8. In connection with any written requests by Viasys that Thermo
Electron take action on behalf of Viasys (including, without limitation,
transfer monies on behalf of Viasys), Viasys hereby agrees to indemnify, defend
and hold harmless each of the Thermo Electron Indemnitees from and against any
and all Indemnifiable Losses resulting from or in connection with action taken
in accordance with Viasys's written instructions.
