Section 6 Shareholder Participation

6.1   Restrictions on voting rights

      Each of our shares carries one vote at our shareholders' meetings. Voting
rights may be exercised only after a shareholder has been recorded in our share
register (Aktienbuch) as a shareholder with voting rights. We may enter into
agreements with banks or financial companies which hold shares for the account
of other persons (nominees) regarding the exercise of the voting rights related
to the shares. Registration with voting rights is subject to restrictions.

      Our shares are cleared and settled through SIS Sega Inter Settle AG. The
shares will not be physically represented by certificates but will be managed
collectively in book-entry form by SIS Sega Inter Settle AG. Shareholders are
therefore not entitled to have their shares physically represented and delivered
in certificate form (aufgehobener Titeldruck). They can, however, request a
statement confirming their ownership of the shares.

6.2   Statutory quorums

      The Articles of Incorporation contain no quorums greater than that set out
by the applicable legal provisions.

6.3   General meetings of shareholders

      The Articles of Incorporation contain no rules on the convocation of the
General meeting of shareholders that differ from applicable legal provisions.

6.4   Agenda

      Shareholders holding shares with a par value of at least CHF 1 million
have the right to request in writing, at least 50 days prior to the day of the
respective shareholders' meeting, that a specific proposal be discussed and
voted upon at such shareholders' meeting.

6.5   Entries into the Share Register

      Only those shareholders with voting rights whose names were recorded in
the company's register of shareholders on the respective closing date may attend
the General Meeting of Shareholders and exercise their voting rights. The Board
of Directors endeavors to set the closing date for registration as close as
possible to the date of the General Meeting, i.e. not more than 3 to 4 weeks
before the General Meeting. There are no exceptions to this rule regarding the
closing date for registration.

Section 7 Changes of Control and Defense Measures

7.1   Duty to Make an Offer

      The Company's Articles of Incorporation do not include "opting-out" or
"opting-up" clauses and accordingly under Article 32 of the Swiss Securities
Exchanges and Securities Trading Act a shareholder who acquires 33 1/3% or more
of the Company's shares is obliged to submit a public offer for the remaining
shares.

7.2   Clauses on Changes of Control

      Our Chief Executive Officer, Lukas Winkler, has an agreement under which
he would become entitled to a special payment upon a change of control of the
Company.

respectively, of the Swiss Code of Obligations are PricewaterhouseCoopers AG,
Zurich, elected for one year. PricewaterhouseCoopers AG commenced their mandate
as statutory and group auditors of INFICON Holding AG in June 2002. The lead
engagement partner, Mr. Stephen Williams, has been responsible for the audit of
INFICON Holding AG since June 2002. The subsidiaries of INFICON Holding AG are
audited by member firms of PricewaterhouseCoopers.

2003 totaled CHF 207,481 (U.S.$167,014).

8.4   Supervisory and Control Instruments pertaining to the audit

      The Audit Committee of the Board proposed the appointment of
PricewaterhouseCoopers AG following a review of offers received from 3 competing
firms of independent accountants for the 2002 reporting year. The Audit
Committee evaluates the performance, fees, and independence of the statutory
auditors and Group auditors each year. Typically the Audit Committee receives a
summary of the scope of work planned by the auditors on an annual basis and
meets with the auditors to review these audit plans. Following the audit work
the auditors submit a report on the results of their work including all
communications required to be made to the audit committee in accordance with
auditing standards generally accepted in the USA. The audit committee meets with
the auditors to discuss and review their feedback. Based on this information, it
determines changes and improvements as necessary.

Section 9 Information policy

      INFICON Holding AG pursues an information policy which is based on
truthfulness, timeliness, and continuity. Matters affecting the share price are
published immediately as ad hoc announcements, in accordance with the obligation
to publish on the SWX Swiss Exchange. Annual financial reports are issued for
the benefit of shareholders and potential investors at the end of March
following the year end closing. Interim financial reports are prepared on a
quarterly basis. Information available for investors can be found at
