                                   ARTICLE II
                               ABOUT CAPITAL STOCK
                                    CHAPTER I
                             ABOUT THE CAPITAL STOCK

SIXTH - The capital stock of the Company is variable. The minimum fixed capital
without right to withdrawal is $480,713,069.97 (four hundred eighty million
seven hundred thirteen thousand sixty-nine pesos and 97/100 National Currency)
represented by 434,971,287 registered common shares with no-par value, fully
subscribed and paid.

The variable portion of the capital stock may not be higher than ten times the
amount of the minimum fixed capital without right to withdrawal and will be
represented by registered common shares with no-par value.

There shall be only one class of shares, which will grant equal rights and
obligations to their holders. Each share issued due to an increase of the
capital stock or for any other reason will constitute the issuance of a new
series of shares which will be identified with a consecutive number followed by
the year, unless the shareholders' meeting resolves otherwise.

Companies in which this Company is the majority stockholder or holds a majority
equity interest may never invest, directly or indirectly, in shares of this
Company or in shares of any other company which is a majority shareholder of
this Company, or which without being so, said companies know that it is a
shareholder of this Company, except in the case that said companies acquire
shares of this Company to comply with sales options or plans granted or designed
or that may be granted or designed in favor of the employees of said companies.

SEVENTH - The capital stock may be increased or decreased by resolution of an
ordinary or extraordinary shareholders' meeting, as the case may be, in
accordance with the rules contained in this clause.


                                       3


Increases or decreases of the Company's fixed minimum portion of the capital
stock may only be decreed or the maximum limit of the variable portion may only
be modified by resolution of the Extraordinary Shareholders' Meeting to approve
its corresponding amendment to the Company's by-laws. The Company may increase
its capital and issue unsubscribed shares for placement among the general
public, pursuant to the provisions of Article 81 of the Stock Market Law.

Within the limits stipulated in the Sixth Clause of these by-laws, increases or
decreases of the variable portion of the capital stock may be effected by
resolution of the Ordinary Shareholders' Meeting and the respective minutes must
be notarized, without the need of registering the respective public deed in the
Public Registry of Commerce, except when the shareholders exercise their right
to withdrawal, under the terms of the Ninth Clause of the by-laws, or when
increases or decreases of the capital to which section I of article 14 Bis 3 of
the Stock Market Law makes reference, are concerned.

(Sole Circular Art. 8 sec.I subsection "a")

No increase in capital may be decreed until all the shares previously issued
have been fully paid. When adopting the capital increase resolutions, the
Shareholders' Meeting (the" Meeting"), that resolves upon the increase, or any
subsequent Shareholders' Meeting, will determine the terms and rules in
accordance with which said increase is to be carried out.

Shares issued as an increase of the variable portion of the capital stock and
through a resolution of the Meeting resolving that upon their issuance must be
deposited in the Company Treasury so that they could be surrendered as the
shares are subscribed, may be offered for subscription and payment by the Board
of Directors according to the powers granted to the Board by the Shareholders'
Meeting, however it must give Company shareholders the preference of
subscription referred to in this clause.

Capital stock increases may be effectuated by a capitalization from the reserve
of profits pending application or by surpluses or payment in cash or in kind.
For increases by capitalization of reserves of profits pending application or by
surpluses, all the holders that have subscribed shares, paid and outstanding at
the time of said increase will be entitled to the proportional part

                                       4



corresponding to the new shares, issued as a result of the capitalization.

In increases by payment in cash or in kind, shareholders of shares that are
subscribed, paid and outstanding at the time the increase is determined will
have a preference to subscribe the new shares issued or placed in circulation
throughout a period of fifteen days, starting from the date of publication of
the respective notice, in the official newspaper of the Company's place of
business, to which the shareholders give this publication the character of
"Official Gazette" of the place of business, or in the alternate, that date is
calculated as of the date the Meeting is held if all of the shares of the
capital stock are represented at the meeting.

If after the expiration of the term during which shareholders were entitled to
exercise their preferential right by this Clause, there remained unsubscribed
shares, then these are to be offered for subscription and payment under the
conditions and terms determined by the Meeting that resolved the capital stock
increase or by the terms determined by the Board of Directors, in such case, at
a price that may not be lower than the price at which they were offered to the
Company shareholders for subscription and payment.

The shareholders will not enjoy the preferential rights mentioned in the above
paragraphs when the following conditions exist: (i) the merger of the Company,
(ii) conversion of liabilities, (iii) public offering under the terms provided
by Article 81 of the Stock Market Law and the first paragraph of this clause,
(iv) the increase of capital stock by means of payment in kind for the shares
issued, or by canceling Company liabilities, and (v) placing shares acquired by
the Company in accordance to the Tenth Clause of these By-Laws.

Every capital stock increase must be registered in the specific books to be kept
by the Company for these purposes.


                                   CHAPTER II
                      ABOUT DECREASES OF THE CAPITAL STOCK

EIGHTH - Decreases of the minimum fixed portion of the capital stock referred to
in the Seventh Clause of these By-laws, may be effectuated in order to absorb
losses, reimburse shareholders for their shares or release them of payments not
made and for cases

                                       5


where the shareholders exercise their withdrawal rights provided in the Ninth
Clause of these By-laws. The decreases in the minimum fixed portion of the
capital stock in order to absorb losses may be effectuated without the need to
extinguish shares, by virtue of the fact that they are no-par value shares.

NINTH - The reduction of the variable portion of the capital stock may be
effectuated by a partial or complete withdrawal of the shareholders'
contributions, following a previous written notice addressed to the President of
the Board of Directors, of their intentions to withdraw, which will be effective
at the end of the fiscal year in question if the notice is received prior to the
last quarter of the fiscal year, and at the end of the following year, if
received at a later time. However, shareholders may not exercise their right of
withdrawal if as a result of said withdrawal the fixed portion of the capital
stock not subject to withdrawal is affected.

In the event that the President of the Company's Board of Directors received
requests for withdrawals that would result in reducing the total amount of the
minimum fixed portion of the capital stock, the Company will be obligated to
satisfy only those requests whose reimbursement does not cause a reduction of
the minimum fixed portion of the capital stock, giving priority to the requests
it receives first in time.

In the event that the President of the Company's Board of Directors received
various simultaneous requests for withdrawals that would result in reducing the
total amount of the minimum fixed portion of the capital stock, the Company may
only decree the reimbursement of those shares whose withdrawal will not provoke
the reduction of the minimum fixed portion of the capital stock, and said
reimbursement will be effectuated in proportion to the number of shares of each
shareholders' simultaneous request.


The procedure for exercising the right of withdrawal foreseen in this clause, in
addition to complying with the provisions of Articles 220 and 221 of the General
Business Law, will be subject to the condition that the respective reimbursement
will be paid in accordance with the lower of the following two values: (1) 95%
of the quotation value on the Stock Exchange, obtained from the average weighted
price by volume of transactions effected during the last thirty days in which
the Company's shares were negotiated prior to the date on which the withdrawal
is to be effected, during a period not to exceed six months; or (2) the book
value of shares

                                       6


according to the balance sheet corresponding to the closing of the immediately
previous period in which the withdrawal is to become effective, previously
approved by an Ordinary Shareholders' Meeting. In case the number of days in
which the shares were negotiated during the period indicated in the preceding
paragraph is less than 30, then the days that would have been effectively
negotiated will be used. In the event that the shares are not negotiated in said
period, the book value of the shares will be taken. (Sole Circular Art.8, sec.I
subsection "c")

Payment of the reimbursement will be enforceable against the Company as of the
date following the Ordinary Shareholders' Meeting that approved the balance
sheet for the period in which the withdrawal is to be effective.

All decreases of the capital stock will be registered in the specific books to
be maintained by the Company for these matters.

TENTH - The Company may acquire shares of its own capital stock in accordance
with the following procedure: the acquisition will be realized through the Stock
Exchange, at the current market price, and the prohibition established in the
first paragraph of article one hundred thirty-four of the General Business Law
will not apply, provided that the purchase is made against the stockholders'
equity so long as said shares pertain to the company or, in such case, to the
capital stock; in the event that it is resolved to convert them into treasury
shares in which case a resolution of the Shareholders' Meeting will not be
required.

An Ordinary Shareholders' Meeting must expressly resolve, for each fiscal
period, the maximum amount of funds that may be used to purchase its own shares,
the only limitation being that the total amount of funds that may be used for
said purpose may never be greater than the total balance of net profits of the
Company, including withheld profits. On the other hand, the Board of Directors
will designate for such purpose the one or more persons responsible for
acquiring and placing the shares of the Company.

So long as the shares belong to the Company, they may not be represented at any
type of Shareholders' Meetings.

The shares that belong to the Company or in such case, the treasury shares, as
referred to in this first clause, without detriment to the provisions of the
General Business Law, may be placed among the public investors, and for this
latter case, the

                                       7


increase of the capital stock will not require a resolution of a Shareholders'
Meeting or a resolution of the Board of Directors for their placement.

Purchase and placement transactions may never exceed twenty five percent of the
capital stock, in the case of shares other than ordinary shares, or result in a
failure to comply with the requirement to maintain the registration on the list
of securities of the exchange in which they are quoted.

The purchase and placement of shares contemplated in this clause, their proper
reports which are to be presented to an Ordinary Shareholders' Meeting, the
rules for reflecting them in the financial information, as well as the form and
terms in which these transactions are announced to the National Banking and
Securities Commission, to the respective Stock Exchange and to the public
investor, will be subject to the general provisions issued by cited Commission.

ELEVENTH - The corresponding Shareholders' Meeting may resolve the issuance of
shares without voting rights, shares with limitations of other corporate rights
or shares of restricted vote other than those foreseen in article 113 of the
General Business Law, without adhering to what is established in article 198 of
the cited Law, provided that the Company has obtained the express authorization
of the National Banking and Securities Commission and the issuance conforms to
the following:

A) The issuance of shares other than common shares shall not exceed twenty-five
percent of the capital stock that is placed among the public investors, of the
total Company's shares that are also placed in the same market.

B) The issuance of shares other than common shares may be issued up to an
additional twenty-five percent, with prior authorization from the National
Banking and Securities Commission, provided that this last percentage be
represented by shares without the right to vote, with the limitation of other
corporate rights or by shares of restricted vote, which in all cases must be
convertible to common shares in a period no greater than five years, beginning
from the time of their placement.

C) In order to determine the percentages referred to above, neither the shares
nor the trust titles that represent them will be considered, and depending on
the nationality of the shareholder,

                                       8


limit the right to vote in compliance with the applicable legal provisions of
the foreign investment law.

D) No mechanisms may be negotiated or offered to the public investor, jointly,
common shares and restricted shares or with limited vote or without the right to
vote, except that the latter may be convertible into common shares in a maximum
period of five years, or that, depending on the nationality of the shareholder,
the shares or trust titles that represent them limit the right to vote in
compliance with the applicable legal provisions of the foreign investment law.

E) The shares without the right to vote will not be computed for purposes of
determining the quorum for a Shareholders Meeting. Moreover, the shares with
restricted or limited voting rights will only be computed to determine the
quorum, and for the resolutions of the Shareholders Meetings when the
shareholders must be called in order to exercise their right to vote.

(Stock Market Law Art. Bis 3, sec.II)

TWELFTH - In case of cancellation of the registration of the Company's shares in
the Securities Section of the National Registry of Securities and
Intermediaries, either upon the request of the Company or by resolution of the
National Banking and Securities Commission pursuant to the Law, the shareholders
that are titleholders of the majority of the common shares or who have the
possibility to impose their decisions in the ordinary shareholders' meetings or
of appointing the majority of the members of the Company's Board of Directors,
will be obligated to make a public share purchase bid prior to the cancellation.

The shareholders, referred to in the above paragraph, will have the obligation
to place in a trust, for a minimum period of six months, the resources necessary
for purchasing the investors' shares that did not exercised this right at the
same price as the bid; in the event that once the public bid is carried out and
prior to the cancellation of the registration in the Registry, the
aforementioned shareholders do not acquire 100% of the paid capital stock.

The public share purchase bid must be carried out at least at the higher price
between the market value in the Stock Exchange or the share's book value in
accordance with the last quarterly report presented to the Commission and the
Stock Exchange before the beginning of the public offer, except when said value
had been

                                       9


modified according to the criteria applicable to the determination of relevant
information in which case the most recent financial information that the Company
has must be considered. The market value will be the average weighted price by
volume of the transactions that were effected during the last 30 days in which
the Company's shares would have been negotiated prior to the date of the public
bid, during a period that may not exceed six months. In case the number of days
in which the shares were negotiated was less than 30, the days that effectively
would have been negotiated will be taken. In the event that the shares are not
negotiated in said period, the book value of the shares will be taken.

In case the public bid consists of more than one series of shares, the average
of the above paragraph must be taken from each one of the series that will be
cancelled, taking as the market value for the public offering of all the series,
the highest average.

Within the five working days prior to the date the offering begins, the
Company's Board of Directors must present their opinion with regards to their
justification of the price of the public bid, in which they will take into
account the minority shareholders' interests with the purpose of complying with
what is established in article 16, second paragraph of the Stock Market Law and
the opinion of the Audit Committee, which must be revealed in the event that it
is contrary. In case the Board of Directors is facing situations that could
generate a conflict of interest, the Board's opinion must be accompanied by
another opinion issued by an Independent Expert selected by their Audit
Committee, in which special emphasis is given to safeguarding the minority
shareholders' rights.

The shareholders referred to in the first paragraph of this clause will not be
obligated to carry out the public offering for the registry cancellation if the
consent of the shareholders that represent at least 95% of the Company's capital
stock is accredited by means of a resolution from a Meeting, and that the amount
offered for the shares placed between the Great Public Investor, according to
this clause, be less than 300,000 units of investment. The preceding can be done
with the understanding that in order to request and obtain the cancellation, the
Company must create a trust, as referred to in the second paragraph of this
clause, and notify the cancellation and creation of the trust through the SEDI.

What is agreed in this clause will also be applicable to the common certificates
of profit-sharing for shares, as well as the

                                       10


representative share certificates of two or more shares of one or more series of
shares of the Company.

The shareholders obligated to carry out the public offering may request the
Commission to authorize them, taking into consideration the Company's financial
situation and perspectives, to use a different basis for determining the price
referred to in the third paragraph of this clause, provided, however, that they
present the Board of Directors' resolution, with the prior favorable opinion of
the Audit Committee that includes its supporting reasons for justifying a
different price, and accompanied by a report from the Independent Expert that
gives special emphasis to the fact that the price is consistent with article 16
of the Stock Market Law.

(Sole Circular, Art.8, sec.III)

THIRTEENTH - Shares will be represented by certificates which must contain the
requirements of article 125 of the General Business Law; they may cover one or
more shares and will be consecutively numbered and signed by two members of the
Board with their handwritten or facsimile signature.

In the event of loss, destruction or theft of one or more share certificates,
the owner may request the issuance of new certificates, subject to the
provisions of the General Law of Credit Instruments and Transactions. Expenses
involved in the issue of the new certificates will be to the account of the
interested party.

The Company will maintain a share registry as required under Article 128 of the
General Business Law. The Company will recognize as the legitimate holder of the
shares the person who is registered in said Registry. At the request of any
interested party, following the necessary proof, the Company will register in
said book the share transfers and conversions that are effectuated. The Registry
Book will remain closed three days prior each Shareholders' Meeting until the
following day after the Meeting. During this time, no registration will be made
in said Book.

The alternate will enter into office in the event of a resignation or temporary
