2.   Services.

     2.1 Services Generally. Except as otherwise provided herein, Providing
Company shall provide or cause to be provided to Receiving Company the services
(the "Services") described in Exhibit I hereto. The Services shall be provided
by Providing Company on a continuous basis for the term of the Agreement set
forth in Section 3.1. Receiving Company shall not be required to furnish
specific orders for Services to be provided by Providing Company hereunder.

     2.2 Additional Services. From time to time after the Effective Date, the
Parties may identify additional Services that Providing Company will provide to
Receiving Party in accordance with the terms and conditions of this Agreement
(the "Additional Services"). Accordingly, the Parties shall amend this Agreement
to include Additional Services on Exhibit II hereto.

     2.3 Obligation to Provide Additional Services. Except as set forth in the
next sentence, Providing Company shall be obligated to perform, at a reasonable
charge, any Additional Service that: (A) was provided by Providing Company or
its predecessor in interest immediately prior to the Transfer Date and that
Receiving Company reasonably believes was inadvertently or unintentionally
omitted from the list of Services or (B) is essential to effectuate an orderly
transition following the Inficon Restructuring unless such performance would
significantly disrupt Providing Company's operations or materially increase the
scope of its responsibility or obligations under this Agreement. If Providing
Company reasonably believes the performance of Additional Services required
under subparagraphs (A) or (B) would significantly disrupt its operations or
materially increase the scope of its responsibility or obligations under this
Agreement, Providing Company and Receiving Company shall negotiate in good faith
to establish the terms under which Providing Company can provide such Additional
Services and use their best efforts to reach an agreement thereon, but Providing
Company shall not be obligated to provide such Additional Services if, following
good faith negotiation, it is unable to reach agreement with Receiving Company.

3.   Term.

                  The term of this Agreement shall commence on the Effective
Date and shall remain in effect for an unlimited period of time, unless
terminated pursuant to Section 7 or agreed otherwise by the parties.

4.   Compensation.

     4.1 Fees for Services. Receiving Company shall pay Providing Company the
service fee set forth on Exhibit I or, if applicable, Exhibit II hereto, for
each of the Services listed therein as adjusted, from time to time, in
accordance with the process and procedures established under Section 4.4 hereof.
Such service fee shall be based on a fixed annual amount to be calculated on the
budgeted direct or indirect cost of providing such Services hereunder plus seven
percent (7%) and remain fixed through the end of the current year unless
Additional Services are provided at the request of the Receiving Company in
accordance with Section 2.3 of this Agreement. The Parties also intend for the
service fee payable hereunder to be easy to administer and, therefore,

                                       3
<PAGE>

hereby acknowledge it may be counterproductive to try to recover every cost,
fee, or expense, particularly those that are insignificant or de minimis. If the
Providing Party has determined that the estimated fee for the next calendar year
will exceed, or be less than, the fee for the current year, it shall notify the
Receiving Party of such determination no later than October 31 of the current
year and in case of a fee increase provide the Receiving Party with proper
documentation in support of its determination. The Parties shall discuss any
such situation and use their best efforts to reach an agreement on the fee to be
paid for the following calendar year; provided, however, that failure to reach
agreement on a fee increase proposed by the Providing Party shall not justify
stopping the provision of, or payment for, Services under this Agreement but
that the Receiving Party may terminate the agreement pursuant to Section 7.1(a)
of this Agreement.

     4.2 Payment Terms. Providing Company shall bill Receiving Company monthly
for all fees pursuant to this Agreement. Such bills shall be accompanied by
reasonable documentation or other reasonable explanation supporting such
charges. The service fee shall be due on the first day of each month and shall
be payable by Receiving Company within fifteen (15) days after receipt of a
proper invoice therefor. Late payments beyond sixty (60) days of the date of the
invoice shall be subject to an interest charge at 8 percent (8 %) per annum of
the invoiced amount, calculated on a daily basis, commencing on the sixty-first
day of the date of the invoice.

     4.3 GST.The amounts determined in accordance with this Section 4 are
exclusive of GST (which shall be paid by the Receiving Company in the manner and
the rate prescribed by law from time to time) and it is the responsibility of
both the Receiving Company and the Providing Company to ensure that the correct
GST treatment is applied in respect of a Service provided.

     4.4 Performance Under Ancillary Agreements. Notwithstanding anything to the
contrary contained herein, Receiving Company shall not be charged under this
Agreement for any obligations that are specifically required to be performed
under any Ancillary Agreement and any such other obligations shall be performed
and charged for (if applicable) in accordance with the terms of such other
Ancillary Agreement.

     4.5 Accounting. Before the Transfer Date, the Parties shall agree on a
process and procedure for conducting internal audits and making adjustments to
fees as a result of the movement of employees and functions between Parties, the
discovery of errors or omissions in fees, as well as a true-up of amounts owed.
In no event shall such processes and procedures extend beyond one (1) year after
completion of a particular Service.

     4.6 Pricing Adjustments. In the event of a tax audit adjustment relating to
the pricing of any or all Services provided pursuant to this Agreement in which
it is determined by a taxing authority that any of the fees, individually or in
the aggregate, did not result in an arm's-length payment, as determined under
internationally accepted arm's-length standards, then the Parties shall agree to
make corresponding adjustments to the fees in question for such period to the
extent necessary to achieve arm's-length pricing. Any adjustment made pursuant
to this Section 4.6 shall be reflected in the Parties' legal books and records,
and the resulting overpayment or underpayment shall create an obligation to be
paid in the manner specified in Section 4.2.

                                       4
<PAGE>

5.   General Obligations; Standard of Care.

     5.1 Performance of Providing Company. Providing Company shall maintain a
high professional standard of care in rendering the Services hereunder. Subject
to Section 6, Providing Company shall maintain sufficient resources to perform
its obligations to provide Services hereunder. Providing Company shall use
reasonable efforts to provide Services to Receiving Company in accordance with
the policies, procedures and practices in effect before the date hereof and
shall exercise the same care and skill as it exercises in performing similar
services for itself.

     5.2 Performance of Receiving Company. Receiving Company shall use
reasonable efforts, in connection with receiving Services, to follow the
policies, procedures and practices in effect before the date hereof, including
providing information and documentation sufficient for Providing Company to
perform the Services and making available, as reasonably requested by the
Providing Company, sufficient resources and timely decisions, approvals and
acceptances in order that Providing Company may accomplish its obligations to
provide Services hereunder in a timely manner.

     5.3 Changes in Provision of Services. The Parties acknowledge that
Providing Company may make changes from time to time in the manner of performing
the Services if the Providing Company is making similar changes in performing
similar services for itself and if Providing Company furnishes to Receiving
Company reasonable advance notice of not less than three month regarding such
changes.

     5.4 Responsibility for Errors; Delays. Providing Company's sole
responsibility to Receiving Company:

         (a)  for errors or omissions in Services, shall be to furnish correct
              information, payment and/or adjustment in the Services, at no
              additional cost or expense to Receiving Company; provided
              Receiving Company must promptly advise Providing Company of any
              such error or omission of which it becomes aware after having used
              reasonable efforts to detect any such errors or omissions in
              accordance with the standard of care set forth in Section 5.1; and

         (b)  for failure to deliver any Service because of impracticability,
              shall be to use reasonable efforts, subject to Section 6.2, to
              make the Services available and/or to resume performing the
              Services as promptly as reasonably practicable.

     5.5 Good Faith Cooperation; Consents. The Parties will use good faith
efforts to cooperate with each other in all matters relating to the provision
and receipt of Services. Such cooperation shall include exchanging information,
providing electronic access to systems used in connection with Services,
performing true-ups and adjustments and obtaining all third party consents,
licenses, sublicenses or approvals necessary to permit each Party to perform its
obligations hereunder. The costs of obtaining such third party consents,
licenses, sublicenses or approvals shall be borne by the Receiving Company. The
Parties will maintain documentation

                                       5
<PAGE>

supporting the information contained in Exhibit I hereto and cooperate with each
other in making such information available as needed in the event of a tax
audit, whether in the country of the Providing Company or any other country.

     5.6 Alternatives. If Providing Company reasonably believes it is unable to
provide any Service because of a failure to obtain necessary consents, licenses,
sublicenses or approvals pursuant to Section 5.5 or because of impracticability,
the Parties shall cooperate to determine the best alternative approach. Until
such alternative approach is found or the problem otherwise resolved to the
satisfaction of the Parties, Providing Company shall use reasonable efforts,
subject to Section 6.1 and Section 6.2, to continue providing the Service or, in
the case of systems, to support the function to which the system relates or
permit Receiving Company to have access to the system so Receiving Company can
support the function itself. To the extent an agreed upon alternative approach
requires payment above and beyond that which is included in the Providing
Company's fee for the Service in question,such payment shall be made by
Receiving Company unless otherwise agreed in writing.


6.  Certain Limitations.

     6.1 Impracticability. Providing Company shall not be required to provide
any Service to the extent the performance of such Service becomes
"impracticable" as a result of a cause or causes outside the reasonable control
of Providing Company including unfeasible technological requirements, or to the
extent the performance of such Services would require Providing Company to
violate any applicable laws, rules or regulations or would result in the breach
of any software license or other applicable contract or any Ancillary Agreement.

     6.2 Additional Resources. Except as provided in the relevant Exhibit for a
specific Service, in providing the Services, Providing Company shall not be
obligated to: (i) hire any additional employees; (ii) maintain the employment of
any specific employee; (iii) purchase, lease or license any additional equipment
or software; or (iv) pay any costs related to the transfer or conversion of
Receiving Company's data to Receiving Company or any alternate supplier of
Services.

         (b) Subject to the provisions of Section 14 below, any Party may

and does not cure such breach (or does not take reasonable steps required under
the circumstances to cure such breach going forward) within sixty (60) business
days after being given written notice of the breach; provided, however, that the
non-terminating party may request that the parties engage in a dispute
resolution negotiation as specified in Section 14 below prior to termination for
breach; and

or with respect to any one or more of the Services, if a Change of Control

upon being notified in writing of such Change of Control, unless the terminating
Party has consented in writing to such Change of Control.

     7.2 Survival. Those Sections of this Agreement that, by their nature, are
intended to survive termination will survive in accordance with their terms.

one or more, but less than all Services, this Agreement shall continue in full
force and effect with respect to any Services not terminated hereby.

     7.3 Effect of Termination. In the event of a termination, all outstanding

         Each Party shall be excused for any failure or delay in performing any

the parties' negotiating teams shall meet and make a good faith attempt to

accordance with the International Rules of Conciliation and Arbitration of the

such Rules. The language of any such arbitration shall be English and the forum
shall be Singapore. The arbitration shall be held as soon as practicable after
the end of such fifteen (15) day negotiation period. Except as provided below in

negotiation or arbitration. In the event that litigation is commenced under this
Section 14.3, the Parties agree to continue to attempt to resolve any dispute
according to the terms of Sections 14.1 and 14.2 during the course of such
litigation proceedings under this Section 14.3.

final judgment in any proceedings brought in such a court shall be conclusive
and binding upon such Party and may be enforced in any court of the jurisdiction
of which it is subject by a suit upon such judgment; provided that service of
process is effected upon such party in accordance with the laws of the

     or to such other address as the Party to whom notice is given may have
     previously furnished to the others in writing in the manner set forth
     above. Any notice or communication delivered in person will be deemed
     effective upon delivery. Any notice or communication sent by telecopy or by
     air courier will be deemed effective on the first business day at the place
     at which such notice or communication is received following the day on
     which such notice or communication was sent. Any notice or communication
     sent by registered or certified mail will be deemed effective on the third
     business day at the place from which such notice or communication was
     mailed following the day on which such notice or communication was mailed.
     As used in this Agreement, "business day" means day other than a Saturday,
     a Sunday or a day on which banking institutions located in the
     jurisdictions where Receiving Company and Providing Company are located are
     authorized or obligated by law or executive order to close.

     15.6 Nonassignability. Except as specifically permitted under Section 9
above, no Party may, directly or indirectly, in whole or in part, whether by
operation of law or otherwise, assign or transfer this Agreement, without the
prior written consent of the other Party hereto, and any attempted assignment,
transfer or delegation without such prior written consent shall be voidable at
the sole option of the other Party. Notwithstanding the foregoing, any Party (or
its permitted successive assignees or transferees hereunder) may assign or
transfer this Agreement as a whole without consent to an entity that succeeds to
all or substantially all of the business or assets of such Party. Without
limiting the foregoing, this Agreement will be binding upon and inure to the
benefit of the Parties and their permitted successors and assigns.

     15.7 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 will nevertheless
remain in full force and effect so long as the economic or legal substance of
the transactions contemplated is not affected in any manner materially adverse
to any party. Upon such determination that any term or other provision is
invalid, illegal or incapable of being enforced, the Parties will negotiate in
good faith to modify this Agreement so as to effect the original intent of the
Parties as closely as possible.

     15.8 No Waiver; Remedies Cumulative. No failure or delay on the part of any
Party in the exercise of any right hereunder will impair such right or be
construed to be a waiver of, or acquiescence in, any breach of any provision of
this Agreement, nor will any single or partial exercise of any such right
preclude other or further exercise 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.

     15.9 Amendment. No change or amendment will be made to this Agreement
except by an instrument in writing signed on behalf of each of the Parties to
this Agreement.
