provided above should no longer meet the joint conditions defined above

automatically be deemed to have retired one calendar month after the joint
conditions are no longer met.

Should the number of censeurs meeting the joint conditions as defined above
(employment in the group and membership of a mutual fund) fall below the number
of two for any reason whatsoever, the Board of Directors must make up its
numbers within three months either by appointment upon the affirmative vote of
the majority of the directors present or represented, subject to ratification by
the nearest shareholders' meeting, or by calling a Shareholders' Meeting to
appoint a censeur meeting the conditions defined hereunder.

Shareholders' Meeting the appointment of one or more censeurs who do not meet
the above requirements, among the shareholders or not, it being specified that
total number of censeurs shall not exceed six.

yearly basis and allocated by the board of directors."

     with the holer at the places mentioned in the notice of the Meeting; these
     formalities should be completed at least three days before the Meeting,
     unless the Board of Directors decides otherwise.

     Subject to the terms and conditions defined by regulations and the
     procedures defined by the Board of Directors, Shareholders may participate
     and vote in all Ordinary or Extraordinary Shareholders' Meetings by
     video-conferencing or any telecommunications method that allows

--------------------------------------------------------------------------------

5.   The Meeting may be rebroadcast by video-conferencing or remote
     transmission. If applicable, this will be mentioned in the notice of
     Meeting.

6.   Any Shareholder who has demonstrated his intention to attend the
     Shareholders' Meeting, issued a mail vote, or given a proxy by producing a
     certificate of non-transferability issued by the custodian of the shares
     may transfer all or part of the shares for which he has made known his
     intention to attend the Meeting, transmitted his vote or proxy, provided
     that he notifies the representative authorized by the company so as to
     allow his vote or proxy to be canceled or the number of shares and
     corresponding votes to be changed, under the conditions and within the
     deadlines stipulated by law and regulations.

7.   The Shareholders' Meeting shall be chaired either by the Chairman or Vice
     Chairman of the Board of Directors, or by a director appointed by the Board
     of Directors or by the Chairman.

     Shareholders shall appoint the officers of the Meeting made up of the
     Chairman, two tellers and a secretary.

     descending order until the duties are accepted.

8.   Copies or extracts of the minutes may be authentificated by the Chairman of
     the Board of Directors, the secretary of the Shareholders' Meeting, or the

                          ARTICLE 22 -- VOTING RIGHTS

Without prejudice to the following provisions, each member of the Shareholders'
Meeting has as many votes as shares that he owns or represents.

However, double voting rights are attached to all fully paid up registered
shares, registered in the name of the same holder for at least three years.

Double voting rights shall be cancelled as of right for any share that is
converted into a bearer share or whose ownership is transferred. However, the
period set here above shall not be interrupted, nor existing rights cancelled,
where ownership is transferred, the shares remaining in registered form, as a
result of intestate or testamentary succession, the division between spouses of
a common estate, or donation inter vivos in favor of a spouse or heirs.

Whatever number of shares a Shareholder possesses, directly and/or indirectly,
he may not cast, as single votes in his own name or as a proxy, more than 8% of
the votes attached to the shares present or represented when any motion at a
Shareholders' Meeting is put to the vote. This limit may be exceeded if such
Shareholder is further entitled to double votes, in his own name or as a proxy,
taking into account such additional voting rights only. However, the total
number of votes cast may not under any circumstances whatsoever exceed 16% of
the votes attached to the shares present or represented. Indirectly held shares
and shares treated in the same way as owned shares as defined by the provisions
of Articles L 233-7 et seq. of the Commercial Code shall be taken into account
when applying the above mentioned limit.

The limitation instituted in the preceding paragraph automatically becomes null
and void from that time when an individual or a legal entity, acting alone or in
concert with one or more individuals or legal entities, comes to hold at least
66.66% of the total number of the Company's shares, as the result of a public
offering to purchase or exchange relating to all of the Company's shares. The
Board of Directors agrees that at the announcement of such offerings, such
invalidation will take effect.

                                                                              13

--------------------------------------------------------------------------------

The limitation instituted in paragraph 4 above does not apply to the chairman of
the Shareholders' Meeting casting a vote pursuant to proxies received in
accordance with the legal obligation deriving from Article L. 225-106 al.7 of
the Commercial Code.

Voting rights in all ordinary, extraordinary or special Shareholders' Meetings
belong to the usufructuary.

                          ARTICLE 23 -- FINANCIAL YEAR

The financial year shall begin on January 1st and end on December 31st.

                                                                              14

--------------------------------------------------------------------------------

                      ARTICLE 24 -- ALLOCATION OF PROFITS

The difference between the proceeds and the expenses of the financial year,
after provisions, constitutes the profits or the losses for the financial year.
From the profits, minus previous losses, if any, shall be deducted the sum of 5%
in order to create the legal reserves, until such legal reserves are at least
equal to 1/10th of the share capital. Additional contributions to the legal
reserves will be required if the legal reserves fall below, for any reason, that
fraction.

The distributable profits shall be the profits for the financial year minus the
previous losses and the above-mentioned deduction plus income carried over. The
Shareholders' Meeting, on a proposal of the board, may decide to carry over some
or all of the profits, to allocate them to reserve funds of whatever kind or to
distribute them to the Shareholders as a dividend.

Besides, the Shareholders' Meeting may decide the distribution of sums deducted
from the optional reserves, either as initial or additional dividends or as
special distribution. In this case, the decision indicates clearly the items
from which the said sums are deducted. However, the dividends are deducted first
from the distributable profits of the financial year.

The ordinary Shareholders' Meeting may grant each Shareholder, for all or part
of the dividend distributed or the interim dividend, the option to receive
payment of the dividend or interim dividend in cash or in shares.

The Shareholders' Meeting or the Board of Directors, in the case of an interim
dividend, fix the date from which the dividend shall be distributed.

                   ARTICLE 25 -- DISSOLUTION AND LIQUIDATION

The Shareholders' Meeting, under the quorum and majority conditions laid down by
law, may, at any time and for any reason whatsoever, decide the early
dissolution of the Company.

When the Company reaches its due date, or in the event of early dissolution, the
Shareholders' Meeting shall decide the manner of liquidation, appoint one or
more liquidators and set their powers, their terms of office and their
remuneration.

In the event of the death, resignation or indisposition of the liquidators the
ordinary Shareholders' Meeting, called under the condition laid down by law,
shall take steps to replace them.

The Shareholders' Meeting shall retain the same powers during liquidation as in
the Company's course of business.

On completion of the liquidation the Shareholders shall be called to approve the
liquidator's accounts and discharge him and to record the closing of the
liquidation.

The liquidator(s) shall carry out their duties under the conditions laid down by
law. In particular, they shall realize all the Company's movable and fixed
assets, including by private treaty, and extinguish all its liabilities. They
may also, with the authorization of the extraordinary Shareholders' Meeting,
transfer the Company's entire assets or contribute them to another company, in
particular by way of a merger.

Assets remaining after all liabilities have been extinguished shall first be
used to pay Shareholders a sum equal to the paid up and non-redeemed capital.
Any surplus shall constitute profits and shall be divided between all the
Shareholders, subject to rights related to shares of different classes, if any.

                                                                              15

                             ARTICLE 26 -- DISPUTES

Any disputes that may arise during the Company's term or at its liquidation,
whether between Shareholders and the Company or between Shareholders themselves
where they concern Company matters, shall be subject to the jurisdiction of the
competent courts.

                                                                              16<PAGE>
