I THE NOTARY, with the documents exhibited by the person herein appearing, attest that the current bylaws of "EMPRESAS ICA SOCIEDAD CONTROLADORA", SOCIEDAD DE RESPONSABILIDAD LIMITADA DE CAPITAL VARIABLE read as follows: CLAUSES TITLE FIRST NAME, PURPOSE, DOMICILE AND DURATION FIRST.- The name of the company is EMPRESAS ICA SOCIEDAD CONTROLADORA and this name will always be followed by the words SOCIEDAD ANONIMA DE CAPITAL VARIABLE or the abbreviation "S.A.

THIRD.- The domicile of the company will be Mexico City, Federal District but it may establish agencies or branches in or out of the Republic, without such circumstance being understood as a change of domicile FOURTH.- The duration of the Company is ninety nine years, starting from January 1, nineteen ninety two. FIFTH.- No foreign person, whether a natural person or a corporate entity, or Mexican company that does not have the foreigners' exclusion clause in its bylaws may have any direct or indirect participation or may own company shares. The Company will never acknowledge rights of shareholders to the above mentioned investors and companies. If for any reason any of said persons, investors or companies acquire an equity interest or become the owner of one or more company shares, thereby contravening the above mentioned provision, it is agreed as of this time that said participation will be null and void and consequently cancelled and the equity interest in question will have no value nor will the certificates that represent it, and the capital stock will be reduced by an amount equal to the value of the cancelled participation. TITLE SECOND SIXTH.- The capital stock is variable. The minimum fixed capital not subject to withdrawal is $480,713,069.11 represented by 434,971,287 registered common no-par shares, fully subscribed for and paid in. The variable portion of the capital stock may not be higher than ten times the amount of the minimum fixed portion without the right of withdrawal and will be represented by registered no-par shares. There will be only one class of shares, which will grant equal rights and obligations to their holders. (Seals: UNITED MEXICAN STATES - HECTOR TREJO ARIAS - NOTARY PUBLIC 234 OF THE FEDERAL DISTRICT, MEXICO, D.F.) 7 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. (Seals: UNITED MEXICAN STATES - HECTOR TREJO ARIAS - NOTARY PUBLIC 234 OF THE FEDERAL 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.

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 (Seals: UNITED MEXICAN STATES - 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.
