                  Each share issue for an increase of the capital stock or for
any other reason will constitute a series which will be designated 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 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 company.

                  SEVENTH.- The capital stock may be increased by a resolution
of a general regular or extraordinary shareholders' meeting, as the case may be,
in accordance with the rules contained in this Clause. Increases of the fixed
minimum portion of the capital stock may only be decreed and the limit of the
variable portion may only be modified by a resolution of the Extraordinary
Shareholders' Meeting and the resulting amendment of these bylaws. 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 Securities
Market Law.

                  Within the limits stipulated in Clause Sixth of these bylaws,
increases of the variable portion of the capital stock may be effected by a
resolution of the General Regular Shareholders' Meeting and the respective
minutes must be notarized, without the need of amending the bylaws or of
registering the respective deed in the public registry of commerce. No increase
may be decreed before all shares previously issued have been fully paid in. When
adopting the respective resolutions, the Shareholders' Meeting that resolves
upon the increase or any subsequent Shareholders' Meeting will determine the
term and rules in accordance with which said increase is to be carried out.

                  Shares issued in virtue of an increase of the variable portion
of the capital stock and which by a resolution of the Meeting that resolved upon
their issue must be deposited in the Company Treasury to be surrendered as they
are

8

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, in every case giving Company shareholders the preference referred to in
this article. Capital stock increases may be effected by a capitalization of
reserve of profits pending application or surpluses or by payment in cash or in
kind. In increases by capitalization of reserves, profits pending application or
surpluses, all holders of shares that are subscribed, paid and outstanding at
the time of said increase will be entitled to the proportional part
corresponding to them of 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 in 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 its domicile
and in one of the most widely distributed newspapers at the corporate domicile
or calculated as of the date the Meeting is held, if all the shares into which
the capital stock is divided are represented at the meeting.

                  If after the expiration of the term during which shareholders
were entitled to exercise the preferential right granted to them by this Clause,
there remained unsubscribed shares, they are to be offered for subscription and
payment under the conditions and terms determined by the meeting that resolved
upon the capital stock increase or in 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.

                  Every capital stock increase must be registered in the
registry book to be kept by the Company for said purpose.

                  EIGHTH.- Reductions of the fixed portion of the capital stock
will be made by resolution of the Extraordinary Shareholders' Meeting and the
resulting amendment of the bylaws, complying in such case, with the provisions
of article ninth of the General Law of Commercial Companies. Except in the case
where a reduction of the capital stock results from the exercise of the
withdrawal right

(Seals: UNITED MEXICAN STATES -
HECTOR TREJO ARIAS - NOTARY
PUBLIC 234 OF THE FEDERAL
DISTRICT, MEXICO, D.F.)

9

referred to in Clause Ninth of these bylaws, the reductions of the variable
portion of the capital stock may be resolved by a Regular Shareholders' Meeting,
the only formality required being that the respective minutes be notarized,
without the need of registering the respective deed in the Public Registry of
Commerce.

                  The capital stock may be reduced to absorb losses, reimburse
shareholders or discharge them from payments not made, and for cases where
shareholders exercise the withdrawal right referred to in Clause Ninth of these
Bylaws. Capital stock reductions to absorb losses will be effected without the
need of extinguishing shares, in virtue of the fact that they are no-par shares.

                  NINTH.- The reduction of the variable portion of the capital
stock may be effected by a partial or complete withdrawal of shareholders'
contributions, following a bona fide notice given to the Company, of their
intention to withdraw, which will be effective at the end of fiscal period in
question, if notice is received prior to the last quarter of the fiscal period,
and at the end of the following period, 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.

                  If the company receives requests for withdrawal that results
in reducing the capital stock to less than the minimum, the Company will be
required to satisfy only those requests that will not produce said result,
giving preference to the first received, in terms of time.

                  If the Company simultaneously receives various requests for
withdrawal, the effect of which is to reduce the capital stock to less than the
minimum, the Company will reimburse only those shares whose reimbursement does
not cause a reduction of the capital stock to less than a minimum and said
reimbursement will be effected in respect to each requesting shareholder,
proportionately to the number of shares, the reimbursement of which was
requested simultaneously.

                  The procedure for exercising the right of withdrawal, in
addition to complying with the provisions of Articles 220 and 221 of the General
Law of Commercial Companies, will be subject to the condition that the
respective

10

reimbursement will be paid in accordance with the lower of the following two
values: 95% of the quotation value on the Stock Exchange, obtained from the
average number of transactions effected throughout the thirty days in which the
Company shares were quoted prior to the date on which the withdrawal is to be
effected, or the book value of shares according to the financial position
corresponding to the close of the period in which the withdrawal is to be
effected, previously approved by the General Regular Shareholders Meeting.

                  Payment of the reimbursement will be enforceable against the
Company as of the date following the holding of the General Regular Shareholders
Meeting that approved the financial situation statements for the period in which
the withdrawal is to be effected.

                  All reductions of the capital stock will be registered in a
specific book to be maintained by the Company for these cases.

                  TENTH.- The company may acquire shares of its own capital
stock pursuant to article fourteen Bis 3 through the Securities Exchange, at the
current market price, and the prohibition established in the first paragraph of
article one hundred thirty four of the General Corporation 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.

                  The General Regular Shareholders Meeting must expressly
resolve, for each fiscal period, the maximum amount of funds that may be
appropriated to purchase its own shares, the only limitation being that the
total amount of funds that may be appropriated to said purpose may never be
higher 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 shares pertain to the Company, they may not be
represented at Shareholders Meetings at any time.

DISTRICT, MEXICO, D.F.)

11

                  Company shares that pertain to the company or in such case,
treasury shares, without detriment to the provisions of the General Corporation
Law, may be placed among the public investors, and for this latter case, the
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 give rise to a
case in which they exceed twenty five percent of the capital stock, in the case
of shares other than ordinary shares, or that results 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, the reports on them which are to be presented to the General Regular
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.

                  TENTH BIS.- In the event of a cancellation of registration of
the Company shares in the Securities Section of the National Registry of
Securities and Brokers, whether at the request of the Company or by resolution
of the National Securities Commission in the terms of the Law, shareholders who
have control of the Company will be required to make a public purchase offer
prior to their cancellation. Shareholders who hold control of the Company will
be required to make a public offer for purchase at the price which is the higher
of the average of the closing price for transactions effected during the last
thirty days during which the shares were quoted, or the accounting value of the
shares, according to the last quarterly report presented to the National
Securities Commission and to the Mexican Securities Exchange prior to the offer.
Notwithstanding the foregoing, shareholders who have control of the Company will
not be required to make a public offer if it is evidenced that cancellation of
the registration was resolved by all the shareholders.

12

                  This clause may only be modified by a resolution of the
Extraordinary Shareholders' Meeting with a minimum voting quorum of 95% of the
capital stock and the prior approval of the National Securities Commission.

                  ELEVENTH.- Shares will be represented by certificates which
must satisfy the requirements of article 125 of the General Corporation 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 a loss, destruction or theft of one or more
share certificates, the owner may request the issue 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 on the account of
the interested party.

                  The Company will maintain a share registry in the terms of
Article 128 of the General Corporation Law. The Company will consider as the
legitimate holder of the shares the person who is registered as such 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
effected. The Registry Book will remain closed from the third day prior to the
holding of each Shareholders Meeting until the day following said holding,
during which no registration will be made in said Book.

                                   TITLE THIRD
                        COMPANY MANAGEMENT AND VIGILANCE

                  TWELFTH.- Company management will be vested in the Board of
Directors formed by at least five and a maximum of twenty members of the Board
of whom at least twenty five percent must be independent. For each standing
member, an alternate will be designated; his designation will be made at the
suggestion of the standing director previously established for his substitution,
forming a staff for the purpose of obtaining an effective participation. The
alternate member of the independent director will have the same status.

                  Substitutions will be made in the event of a resignation or
temporary absence of the standing members. The alternate will continue in office
until the

HECTOR TREJO ARIAS - NOTARY
PUBLIC 234 OF THE FEDERAL
DISTRICT, MEXICO, D.F.)

13

cause that gave rise to the absence of the standing member disappears or until
the Meeting makes a new designation.

                  The Board of Directors must be formed by equity directors;
equity directors are defined as those who have a share participation in the
company and who render services to the company, and by independent directors
who, because of their experience, capacity and professional prestige, have been
invited to participate as members of the Board of Directors.

                  The Board of Directors will designate from among its members
the person who is to act as the Chairman of the Board and in the event of the
latter's temporary absence, the General Attorney of the Company will preside and
in the absence of both, the independent director with the greatest seniority and
who is an attorney-at-law will preside.

                  In the event of a permanent absence of the Chairman, the Board
of Directors will be called. The meeting will be presided over by the General
Attorney in order to designate the new Chairman among the directors already
designated. The General Attorney may not be designated as a candidate in the
election process for the new Chairman.

                  The Secretary of the Board of Directors will be named by the
Board. The designation will be made independently of the positions or status
held by the person designated within or outside the company.

                  In addition to the Chairman of the Board, there may be a
President and one or more vice-presidents of the Company who will be named by
the Board of Directors. The President and the one or more Vice-presidents must
be Mexican and may be shareholders, members of the Board or persons unrelated to
the Company; they will represent the Company and will have the powers granted to
them at the time they are designated.

                  One or more Directors, Managers and Assistant Managers may
also exist; they will be designated by the Board of Directors and will have the
powers granted to them at the time of their designation.

14

                  The persons who hold these positions may be shareholders,
members of the Board, members of other administrative bodies or persons
unrelated to the Company.

                  The Chairman of the Board will have the powers and the
responsibilities attributed to him by the laws and these bylaws and particularly
powers to comply and see to compliance with the laws, these Bylaws and the
resolutions of the Shareholders Meeting and of the Board of Directors. The
Chairman will have the tie-breaking vote.

                  THIRTEENTH.- The General Regular Shareholders Meeting will
have the power to designate the number of standing members of the Board of
Directors as it deems appropriate so that they may constitute the Executive
Committee as temporary and revocable agents. The General Regular Shareholders
Meeting may designate, in addition, other standing or alternate members of the
Board of Directors so that, with the same status of temporary and revocable
agents, they may act as alternate members of the Executive Committee and
substitute for standing members during temporary or definitive absences of the
former; the General Regular Shareholders Meeting will determine how said
alternate members are to fulfill their duties.

                  The Executive Committee of the Company, as a collegiate body,
will act and adopt its resolutions by the majority vote of its members and will
have the powers and rights referred to in paragraphs a) to g) inclusive of
Clause Seventeenth of these bylaws.

                  The Executive Committee will inform the Board of Directors of
the resolutions adopted when exercising the powers conferred upon it by this
clause, at least annually or when in the judgment of the Committee, facts or
acts that are significant for the Company occur.

                  The Executive Committee will have the power to designate from
among its members, the persons who will act as the Chairman and Secretary of the
Company, as well as the power to determine the dates for their meetings, with
the understanding that the Chairman of the Executive Committee must be a
standing member of the Board of Directors and the Secretary of the Executive
Committee
