and the relative or special rights in respect of each class of the capital stock of the corporation.



| | A. | Preferred Capital Stock
| | -- | -----------------------

1. Shares of each sub-class ofPreferred CapitalStock may be issued from time to time in one or more series as the Board of Directors may determine, and authority is hereby
expressly granted to the Board of Directors, subject to the provisions of this Article Seventh, to establish and designate series of each sub-class of Preferred CapitalStock and to fix the number of shares to be included
in each such series and the relative rights, preferences and limitations of the shares of each such series. To the extent not set forth in this Articles Seventh, the terms of each such series shall be specified in the resolution or resolutions
adopted by the Board of Directors pursuant to the authority hereinbefore granted providing for the issuance of such shares, which resolution or resolutions shall be recorded with Philippine Securities and Exchange Commission and thereupon be deemed
a part of these Articles of Incorporation. Without limiting the generality of the foregoing, the authority of the Board of Directors shall include the determination, which respect to each series of Preferred CapitalStock, of the
following:

(a) the number of shares to constitute such series and the distinctive designations thereof;

(b) the dividend rate, if any, on the shares of such series (which, if and to the extent the Board of
Directors, in its sole discretion, shall deem appropriate under the circumstances, shall be fixed considering the rate of return on similar securities at the time of issuance of such shares), the terms and conditions upon which and the periods with
respect to which dividends shall be payable, whether and upon what conditions such dividends shall be cumulative and, if cumulative, the date or dates from which dividends shall accumulate;

(c) whether or not the shares of such series shall be redeemable, the limitations with respect to such redemptions, the
time or times when and the manner in which such shares shall be redeemable (including the manner of selecting shares of such series for redemption if less than all shares are to be redeemed) and the price or prices at which such shares shall be
redeemable, which may not be less than (i) the par value thereof plus (ii) accrued and unpaid dividends thereon, nor more than (i) 110% of the par value thereof plus (ii) accrued and unpaid dividends thereon;

(d) whether or not the shares of such series shall be subject to the operation of a purchase, retirement or sinking fund,
and, if so, whether and upon what conditions such purchase, retirement or sinking fund shall be cumulative or non-cumulative, the extent to which and the manner in which such fund shall be applied to the purchase or redemption of the shares of such
series for retirement or to other corporate purposes and the terms and provisions relative to the operation thereof;

(e) the rights to which the holders of shares of such series shall be entitled upon the voluntary or involuntary liquidation, dissolution, distribution of assets or winding up of the corporation, which
rights may vary depending on whether such liquidation, dissolution, distribution or winding up is voluntary or involuntary, and if voluntary, may vary at different dates, provided, however, that the amount which the holders of shares of such series
shall be entitled to receive in the event of any voluntary or involuntary liquidation, dissolution, distribution of assets or winding up of the corporation shall not be more than (i) 110% of the par value of such shares plus (ii) accrued
and unpaid dividends thereon, nor less than (i) the par value thereof plus (ii) accrued and unpaid dividends thereon;

(f) whether or not the shares of such series shall be convertible into or exchangeable for shares of stock of any other class or classes, or any other series of the same class, and, if so convertible or
exchangeable, the price or prices or the rate or rates of conversion and exchange and the method, if any, of adjusting the same, and any other terms or conditions of such conversion or exchange;

(g) the status of shares of such series redeemed, purchased or otherwise reacquired, or surrendered to the corporation on
conversion or exchange; and

(h) any other rights, preferences or limitations of such series, as the Board of
Directors may deem advisable and as shall not be inconsistent with the provisions of these Articles of Incorporation.



---

2. All shares of Preferred CapitalStock shall be of equal rank, preference
and priority and shall be identical in all respects regardless of series, except as to voting rights and otherterms which may be specified by the Board of Directors pursuant to the provisions of subdivision 1 of this Paragraph A.

3. The holders of shares ofPreferred CapitalStock shall be entitled to receive, when, as and if
declared by the Board of Directors out of funds legally available therefore, preferential cash dividends at the rate, under the terms and conditions, for the periods and on the dates fixed by the resolution or resolutions of the Board of Directors,
pursuant to authority hereinbefore granted in this Paragraph A for each series, and no more, before any dividends on the Common Capital Stock (other than dividends payable in Common Capital Stock) shall be paid or set apart for payment with respect
to the same dividend period.

All shares of Preferred CapitalStock of all series shall be of equal rank,
preference and priority as to dividends irrespective of whether or not the rates of dividends to which the same shall be entitled shall be the same and, when the stated dividends are not paid in full, the shares of all series of Preferred
Capital Stock shall share ratably in the payment of dividends including accumulations, if any, in accordance with the sums which would be payable on such shares if all dividends were declared and paid in full, provided, however, that
any two or more series of Preferred Capital Stock may differ from each other as to the existence and extent of the right to cumulative dividends as aforesaid.

4. In the event of any voluntary or involuntary liquidation, dissolution, distribution of assets or winding up of the corporation, the holders of the shares of each series of Preferred CapitalStock then outstanding shall be entitled to receive out of the net assets of the corporation the amount per share fixed by the resolution or resolutions of the Board of Directors to be received by the holders of shares of each such series on
such voluntary or involuntary liquidation, dissolution, distribution of assets or winding up, as the case may be, together with all dividends (whether or not earned) accrued or in arrears, for every share of their holdings of Preferred
CapitalStock, before any distribution or payment shall be made to the holders of the Common Capital Stock, and shall be entitled to no other or further distribution.

All shares of Preferred CapitalStock of all series shall be of equal rank, preference and priority as to the net assets of
the corporation or proceeds thereof to which the same shall be entitled upon voluntary or involuntary liquidation, dissolution, distribution of assets or winding up of the corporation. If, upon any liquidation, dissolution, distribution of assets or
winding up, as the case may be, the net assets of the corporation or proceeds thereof distributable among the holders of the shares of Preferred CapitalStock of all series shall be insufficient to pay in full the preferential amount
aforesaid, then such assets, or the proceeds thereof, shall be distributed among such holders ratably in accordance with the respective amount which would be payable if all amounts payable thereon were paid in full.

For the purposes of this subdivision 4 neither the consolidation nor merger of the corporation with or into any other corporation, nor
any sale, lease, exchange or conveyance of all or any part of the property, assets or business of the corporation shall be deemed to be a liquidation, dissolution, distribution of assets or winding up of the corporation within the meaning of the
provisions of this Article Seventh, unless the Board of Directors of the corporation elects to treat such transaction as a liquidation, dissolution, distribution of assets or winding up of the corporation.

5. The holders of shares of Voting Preferred Stock shall have voting rights at any meeting of the stockholders of the corporation
for the election of directors and for all other purposes, with one vote in respect of each share of Voting Preferred Stock. Except as otherwise provided by law or as otherwise specifically provided in this subdivision 5, the holders of
shares of Non-VotingSerial Preferred Stock shall not be entitled to vote at any meeting of the stockholders for the election of directors or for any other purpose or otherwise to participate in any action taken by the
corporation or its stockholders, or to receive notice of any meeting of stockholders.

The corporation shall not, by an
amendment to the Articles of Incorporation, or by merger or consolidation or in any other manner, change the rights, designations, preferences or other special rights of any series of Preferred CapitalStock, or the qualifications,
limitations and restrictions thereof, in any respect prejudicial to the holders of such series of Preferred CapitalStock without the affirmative vote of the holders of at least a majority of the outstanding shares of such series of
Preferred CapitalStock; provided, however, that without such vote the corporation may (i) increase the authorized number of shares of Preferred CapitalStock or of any series thereof, or (ii) authorize classes
of shares ranking on a parity with Preferred CapitalStock in right of payment of dividends or upon voluntary or involuntary liquidation, dissolution, distribution of assets or winding up of the corporation.



---

6. Shares of Preferred Capital Stock may be issued and sold by the corporation
for such lawful consideration not less than the par value thereof as the Board of Directors shall determine. The ownership of shares of Preferred Capital Stock shall not entitle the owner thereof to any right (other than such right, if
any, as the Board of Directors in its discretion may from time to time grant) to subscribe for or to purchase or to have offered to him for subscription or purchase any shares of any class of stock or other securities of the corporation.
