which should be made available to shareholders on the web site of the Company. The omission of this obligation shall not affect the validity of the notification, but the Directors, Liquidators and Managers of the Company at fault shall be
responsible for any damage suffered by shareholders, irrespective of the administrative sanctions which the Superintendence of Securities and Insurance may apply. However, those meetings attended by the whole of the issued shares with voting rights

CHAPTER FIVE

The Directors Committee and Audit Committee

Article 28: While the Company meets the equity and concentration requirements established in Article 50 bis, or that succeeding or
replacing it, of Law No. 18,046, it shall be obliged to appoint an independent director and a Directors Committee. This Committee shall be governed in its formation, membership, functioning and powers by the provisions of the Chilean Companies
Act and instructions on this subject issued by the Superintendence of Securities and Insurance.

Article 29: Notwithstanding the provisions
of the preceding Article and while the Company is an issuer of securities duly registered with the New York Stock Exchange (NYSE) or any other American national stock exchange, the formation, membership, functioning and powers of the Directors
Committee shall also be governed, where not to be contrary to Chilean law, by the obligatory provision for the so-called Audit Committee in the Sarbanes Oxley Act (SOX) of the United States of America and the instructions issued by the
Securities and Exchange Commission (SEC) and the New York Stock Exchange (NYSE), or the organism or entity that definitively corresponds in accordance with the legislation of the United States of America. In case of a irreconcilable or irremediable
conflict, disagreement or incompatibility between the provisions of Chilean and American legislation for the Directors Committee and the Audit Committee respectively, Chilean law shall prevail over foreign law, although the Board of Directors
may call an Extraordinary Shareholders Meeting to amend the bylaws should this be necessary, and shall have the widest powers, acting within its powers, to solve such conflict, disagreement or incompatibility should this be possible, by the
creation of new committees and/or sub-committees, as also the delegation of part of its powers in accordance with Article 40 of the Chilean Companies Act. The shareholders, directors and Board of Directors of the Company should ensure at all times
that the agreements and policies adopted by it are compatible and harmonious with the provisions of both legislations.

Article 30: The
Directors Committee shall be composed of three members, the majority of whom shall be independent according to the criteria and requirements established for this purpose in Article 50 bis of Law No. 18,046, both at the time of their
appointment and during the whole period in which they perform as members of the Committee. Notwithstanding the above and complementing the provisions of Article 29 above, while the corporation is an issuer of securities duly registered on the NYSE
or any other American national stock exchange, and in order to give strict compliance with the legal and regulatory requirements that the registration involves, all the members of the Directors Committee should also meet the criteria and
requirements of independence prescribed for this purpose by the SOX, SEC and NYSE. Thus, no director who has been elected or appointed as a member of the Directors Committee may therefore have any link, interest or dependence with the
corporation, whether economic, professional, credit or commercial, whatever the amount or nature, nor receive, directly or indirectly, any income, remuneration or compensation from the corporation or any of its subsidiaries which is not by concept
nor has as the sole and exclusive source the duties performed as a member of the Board of Directors, as a member of the Directors Committee or as a member of any other committee or sub-committee of directors of the Company.



---

Article 31:The loss of independence which, according to the laws governing the Company and
these bylaws, affects a member of the Committee, shall generate the following incapacity of the respective director to perform their duties as a director or member of the Directors Committee and therefore they should cease automatically in
that position, notwithstanding their responsibility to the shareholders.

Article 32: The directors appointed as members of the
Directors Committee shall remain as such for the period they were appointed as director and may only resign from this position when they resign as director or having acquired a following incapacity to perform the duties, in which case the
provisions of the preceding Article shall apply. No director elected or appointed as a member of the Directors Committee may be excused from this election or appointment.

Article 33: The meetings of the Directors Committee shall be validly constituted with the absolute majority of its members and its
resolutions shall be adopted by the absolute majority of the members present. The Directors Committee should elect a Chairman from among its members, who shall have the casting vote in the event of a tied vote.

Article 34: The Committee shall have the powers and duties that have been expressly contemplated both in the laws and their regulations, as well
as the rules issued for the purpose by the competent administrative authority, especially those stated in Article 50 bis of Law No. 18,046, and any other matter, mandate, power or duty commended to it by a shareholders or Board meeting.

Article 35: The deliberations, agreements and organization of the Directors Committee shall be governed, in everything applicable, by the
regulations relating to the Board meetings of the Company.

CHAPTER SIX

Balance Sheet, Funds and Earnings

Article 36: As of December 31 of each year, a financial statement with the operations of the Company shall be prepared, and the Board of
Directors shall present this to the Ordinary Shareholders Meeting together with a report analyzing the situation of the Company and the statement of income and the related report provided by the inspectors of accounts and external auditors.
All these documents must reflect clearly the equity position of the Company at the close of the respective year and the profits obtained or losses suffered during the year.

Article 37: On a date no later than the first notification convening the Ordinary Shareholders Meeting, the Board of Directors should make
available to each shareholder registered in the respective register a copy of the duly audited Financial Statements and Annual Report of the Company, including the reports of the external auditors and inspectors of accounts, and their respective
notes. The duly audited balance sheet and statement of income and other information which the law or the Superintendence of Securities and Insurance requires, shall be published on the web site of the Company no less than ten days before the date on
which the meeting to approve them is to be held. The annual report, balance sheet, inventories, minutes of Board and Shareholders Meetings, books and reports of inspectors, must be available to shareholders in the offices of the Company for 15
days prior to the date informed for the meeting. Should the balance sheet and statement of income be altered by the Meeting, the amendments, where corresponding, shall be made available to shareholders within 15 days following the date of the
Meeting.

Article 38: Unless otherwise approved at the respective Meeting with the unanimous vote of the shares issued, a cash dividend
shall be distributed annually to shareholders, pro rata to their shares, for at least 30% of the net income for each year. In any event, the Board of Directors may, under the personal responsibility of the Directors present at the respective
approval, distribute interim dividends during the year as a charge against the profits of that year, provided that there are no accumulated losses. That portion of profits earnings not appropriated by the Meeting to dividends, may be capitalized at
any time, subject to amending the bylaws through the issue of free shares or by increasing the nominal value of the shares, or be retained to meet possible dividend payments in following years.



---

CHAPTER SEVEN

Dissolution and Liquidation

Article 39: The dissolution of the Company shall occur in the cases foreseen in the Law. Dissolution in advance shall only be agreed at an
Extraordinary Shareholders Meeting with the consenting vote of two-thirds of the issued shares with voting rights.

Article 40: Once
the Company is dissolved, the liquidation shall be performed by a Liquidation Committee formed by three people, shareholders or not, chosen by the Shareholders Meeting, and who shall have the powers, duties and obligations established in the
law or regulations. If the Company is dissolved as a result of all the shares being held by one person through an uninterrupted period of at least ten days, liquidation shall be unnecessary.

Article 41: The liquidators shall convene an Ordinary Shareholders Meeting in the month of April each year to report on the state of the
liquidation. Should the liquidation not be completed within two years, a new election of liquidators shall be made, the same persons being re-eligible. The position of liquidators is remunerated and the Ordinary Shareholders Meeting shall set
the remuneration. The position of liquidator is revocable by an Ordinary or Extraordinary Shareholders Meeting. Liquidators shall be suspended from their positions by overriding legal incapacity or by their declaration of bankruptcy.

CHAPTER EIGHT

General Provisions

Article

parties, who will exercise the role as arbitrator in such a proceeding, and must decide according to Law. In the absence of such an agreement, the arbitrator shall be designated by Common Courts at the request of either party, in which case such
nomination must be from attorneys who teach or who have taught for at least three consecutive years as Professors of Economic or Commercial Law in the Department of Law at the Universidad de Chile, Universidad Católica de Chile or Universidad
Católica de Valparaíso. Notwithstanding the above, in the event of a conflict, the plaintiff may withdraw his recognition of the authority of the arbitrator, and submit to the jurisdiction of the Common Justice, a right that cannot be
exercised by the directors, managers, administrators and senior executives of the Company, nor by those shareholders that individually hold, directly and indirectly, shares whose book or market value exceeds 5,000 Unidades de Fomento, according to
