(6) The Corporation, at the option of the Board of Directors, may, at any time permitted by the resolution or resolutions adopted by the Board of Directors providing for the issue of any series of the Preferred Stock and at the redemption price or prices stated in said resolution or resolutions, redeem the whole or any part of the shares of such series then outstanding (the total sum, including accrued dividends, so payable on any such redemption being herein referred to as the “redemption price”). Notice of every such redemption shall be mailed to the holders of record of the shares of Preferred Stock so to be redeemed at their respective addresses as their names shall appear on the books of the Corporation. Such notice shall be mailed at least 30 but no more than 90 days in advance of the date designated for such redemption to such holders. In case of the redemption of a part only of any series of Preferred Stock then outstanding, the shares of such series so to be redeemed shall be selected by lot or in such other manner as the Board of Directors may determine to be equitable.

(7) If, on the redemption date specified in a notice pursuant to paragraph (6), the funds necessary for such redemption shall have been set aside by the Corporation, separate and apart from its other funds, in trust for the pro rata benefit of the holders of the shares so called for redemption, then, notwithstanding that any certificates for shares of Preferred Stock so called for redemption shall not have been surrendered for cancellation, the shares represented thereby shall no longer be deemed outstanding, the right to receive dividends thereon shall cease to accrue from and after the date of redemption so designated and all rights of the holder of any share of Preferred Stock so called for redemption shall, forthwith after such redemption date, cease and terminate, excepting only the right of the holder thereof to receive the redemption price therefor but without interest. Any moneys so set aside by the Corporation and unclaimed at the end of four years from the date designated for such redemption shall revert to the general funds of the Corporation, after which reversion the holders of any share so called for redemption shall look only to the Corporation for payment of the redemption price. Any interest accrued on funds so deposited shall be paid to the Corporation from time to time.

(8) If, after giving of a notice pursuant to paragraph (6) but before the redemption date specified therein, the Corporation shall deposit with a bank or trust company in the Borough of Manhattan, the City of New York, having a capital and surplus of at least $50,000,000, in trust to be applied to the redemption of the shares of Preferred Stock so called for redemption, the funds necessary for such redemption, then from and after the date of such deposit all rights of the holders of the shares of Preferred Stock so called for redemption shall cease and terminate, excepting only the right to receive the redemption price therefor, but without interest, and the right to exercise on or before the date designated for redemption privileges of conversion or exchange, if any, not theretofore expired, and such shares shall not be deemed to be outstanding. Any funds so deposited which shall not be required for such redemption because of the exercise of any such right of conversion or exchange subsequent to the date of such deposit shall be returned to the Corporation. In case the holders of shares of Preferred Stock which shall have been called for redemption shall not, within four years after the date fixed for redemption, claim the amount deposited with respect to the redemption

-7-

thereof, any such bank or trust company shall, to the extent permitted by applicable law, upon demand, pay over to the Corporation such unclaimed amounts and thereupon such bank or trust company shall be relieved of all responsibility in respect thereof to such holder and such holders shall look only to the Corporation for the payment thereof. Any interest accrued on funds so deposited shall be paid to the Corporation from time to time.

(9) Shares of Preferred Stock which have been issued and reacquired in any manner by the Corporation (excluding, until the Corporation elects to retire them, shares which are held as treasury shares but including shares redeemed, shares purchased and retired, whether through the operation of a retirement or sinking fund, or otherwise, and shares which, if convertible or exchangeable, have been converted into or exchanged for shares of stock of any other class or classes or series ) may, subject to any applicable provisions of the laws of the Republic of Panama, have the status of authorized and unissued shares of Preferred stock and be reissued as a part of the series of which they were originally a part or be reclassified and reissued as part of a new series of Preferred Stock created by resolution or resolutions of the Board of Directors or as part of any other series of Preferred Stock, all subject to the conditions or restrictions on issuance set forth in any resolution or resolutions adopted by the Board of Directors providing for the issue of any series of Preferred Stock.

(10) If at any time the Corporation shall have failed to pay dividends in full on the Preferred Stock, thereafter and until dividends in full, including all accrued and unpaid dividends on the Preferred Stock outstanding, shall have been declared and set apart for payment or paid, (a) the Corporation, without the affirmative vote or consent of the holders of at least 66 2/3% in interest of the Preferred Stock at the time outstanding, regardless of series, given in person or by proxy, either in writing or by resolution adopted at an annual or special meeting called for the purpose, at which the holders of the Preferred Stock, regardless of series, shall vote separately as a class, shall not redeem less than all of the Preferred Stock at such time outstanding, other than in accordance with paragraph (16) hereof; (b) the Corporation shall not purchase any Preferred Stock except in accordance with a purchase offer made in writing or by publication (as determined by the Board of Directors) to all holders of Preferred Stock of all series upon such terms as the Board of Directors, in their sole discretion after consideration of the respective annual dividend rates and other relative rights and preferences of the respective series, shall determine (which determination shall be final and conclusive) will result in fair and equitable treatment among the respective series; provided, that (i) unless prohibited by the provisions applicable to any series, the Corporation, to meet the requirements of any retirement or sinking fund provisions with respect to any series, may use shares of such series acquired by it prior to such failure and then held by it as treasury stock and (ii) nothing shall prevent the Corporation from completing the purchase or redemption of shares of Preferred Stock for which a purchase contract was entered into for any retirement or sinking fund purposes, or the notice of redemption of which was initially published, prior to such default, and (c) this paragraph (10) shall not apply to any obligation of the Corporation to purchase any share or shares of Preferred Stock pursuant to the exercise of rights which arise under an agreement if the holders of 66 2/3% in interest of the Preferred Stock of the Corporation outstanding when such agreement was executed were parties to such agreement.

-8-

(11) So long as any Preferred Stock is outstanding the Corporation will not

(a) Declare, or pay, or set apart for payment any dividends (other than dividends payable in stock ranking junior to the Preferred Stock) or make any distribution on any other class of stock of the Corporation ranking junior to the Preferred Stock either as to dividends or upon liquidation and will not redeem, purchase or otherwise acquire, any shares of any such junior class if at the time of making such declaration, payment, distribution, redemption, purchase or acquisition the Corporation shall be in default with respect to any dividend payable on, or any obligation to retire shares of, Preferred Stock, provided that, notwithstanding the foregoing, the Corporation may at any time redeem, purchase or otherwise acquire shares of stock of any such junior class in exchange for, or out of the net cash proceeds from the sale of, other shares of stock of any junior class;

(b) Without the affirmative vote or consent of the holders of at least 66 2/3% of all the Preferred Stock then outstanding regardless of series, given in person or by proxy, either in writing or by resolution adopted at an annual or special meeting called for the purpose, at which the holders of the Preferred Stock, regardless of series, shall vote separately as a class, amend, alter or repeal any of the provisions of this Part A so as adversely to affect the preferences, rights, or powers of the Preferred Stock; provided that the creation of any class of stock ranking prior to the Preferred Stock either as to dividends or upon liquidation or any increase in the authorized number of shares of any such class of stock shall not be deemed to adversely affect the preferences, rights or powers of the Preferred Stock within the meaning of this subparagraph (b);

(c) Without the affirmative vote or consent of the holders of at least 50% of all the Preferred Stock then outstanding, regardless of series, given in person or by proxy, either in writing or by resolution adopted at an annual or special meeting called for the purpose, at which the holders of the Preferred Stock, regardless of series, shall vote separately as a class, create any class or classes of stock ranking prior to the Preferred Stock either as to dividends or upon liquidation, or increase the authorized number of shares of any such class of stock; or

(d) Without the affirmative vote or consent of the holders of at least 66 2/3% of any series of the Preferred Stock at the time outstanding, given in person or by proxy, either in writing or by resolution adopted at an annual or special meeting called for the purpose, at which the holders of such series of the Preferred Stock shall vote separately as a series, amend, alter or repeal any of the provisions in the resolution or resolutions adopted by the Board of Directors providing for the issue of such series so as adversely to affect the preferences, rights or powers of the Preferred Stock of such series; and any vote or consent required by subparagraph (b) above may, to the extent permitted by applicable law, be given and made effective by the filing of an appropriate amendment of the Corporation’s Articles of Incorporation without obtaining the vote or consent of the holders of the Common Stock of the Corporation, the right to give such vote or consent being expressly waived, to the extent permitted by applicable law, by all holders of such Common Stock, unless the action to be taken would substantially adversely affect the rights or powers of the Common Stock; and further, any vote or consent required by subparagraph (d) above may, to the extent permitted by applicable law, be given and made effective by the filing of an appropriate amendment of the

-9-

Corporation’s Articles of Incorporation without obtaining the vote or consent of the holders of any other series of Preferred Stock or of the holders of the Common Stock of the Corporation, the right to give such vote or consent being expressly waived, to the extent permitted by applicable law, by all holders of such other series of Preferred Stock and Common Stock, unless the action to be taken would substantially adversely affect the rights or powers of such other series of Preferred Stock or Common Stock, as the case may be.

(12) Whenever dividends payable on any series of Preferred Stock remain unpaid in an aggregate amount equivalent to six full quarterly dividends, the holders of the Preferred Stock shall have the exclusive and special right, voting separately as a class and without regard to series, to elect two directors of the Corporation. Such right shall be in addition to any other rights which the holders of the Preferred Stock may have to vote in the election of directors. Whenever such right of the holders of the Preferred Stock shall have vested, such right may be exercised initially either at a special meeting of such holders of the Preferred Stock called as provided in paragraph (13) or at any annual meeting of stockholders, and thereafter at annual meetings of stockholders. The right of the holders of the Preferred Stock voting separately as a class to elect members of the Board of Directors of the Corporation as aforesaid shall continue until such time as all dividends accumulated on the Preferred Stock shall have been paid in full, at which time the special right of the holders of the Preferred Stock so to vote separately as a class for the election of directors shall terminate, subject to revesting each and every time the conditions stated in the first sentence of this paragraph (12) occur.

(13) Whenever special voting power has vested in the holders of the Preferred Stock pursuant to paragraph (12), a proper officer of the Corporation shall, upon the written request of the holders of record of at least 10% of the Preferred Stock then outstanding, regardless of series, addressed to the Secretary of the Corporation, call a special meeting of the holders of the Preferred Stock and of any other class or classes of stock having voting power, for the purpose of electing directors. Such meeting shall be held at the earliest practicable date at such place as may be specified in the notice of meeting. If such meeting shall not be called by the proper officers of the Corporation within twenty days after personal service of said written request upon the Secretary of the Corporation, or within twenty days after depositing the same with the Postal Service of the United States of America, by registered or certified mail addressed to the Secretary of the Corporation at its principal office, then the holders of record of at least 10% of the Preferred Stock then outstanding, regardless of series, may designate in writing one of their number to call such meeting at the expense of the Corporation, and such meeting may be called by such person so designated upon the notice required for annual meetings of stockholders and shall be held at the place for the holding of annual meetings of stockholders of the Corporation. Any holder of Preferred Stock so designated shall have access to the stock books of the Corporation for the purpose of causing meetings of stockholders to be called pursuant to these provisions. Notwithstanding the other provisions of this paragraph (13), no such special meeting shall be called during the ninety days immediately preceding the date fixed for an annual meeting of stockholders.

(14) At any meeting held for the purpose of electing directors at which the holders of the Preferred Stock shall have the special right, voting separately as a class,

-10-

to elect directors as provided in paragraph (12), the presence, in person or by proxy, of the holders of 33 1/2% of the Preferred Stock then outstanding shall be required to constitute a quorum of such class for the election of any director by the holders of the Preferred Stock as a class. At any such meeting or adjournment thereof, (a) the absence of a quorum of the Preferred Stock shall not prevent the election of directors other than those to be elected by the Preferred Stock voting as a class and the absence of a quorum for the election of such other directors shall not prevent the election of the directors to be elected be the Preferred Stock voting as a class, and (b) in the absence of either or both such quorums, a majority of the holders present in person or by proxy of the stock or stocks which lack a quorum shall have power to adjourn the meeting for the election of directors which they are entitled to elect from time to time without notice other than announcement at the meeting until a quorum shall be present.

(15) Any director elected pursuant to paragraphs (12), (13) and (14) shall continue in office until the next annual meeting or until his successor shall have been so elected or until termination of the right of the holders of the Preferred Stock to vote as a class for directors. Whenever special voting power pursuant to paragraph (12) is vested in the holders of the Preferred Stock, any vacancy in the Board of Directors shall be filled only by vote of a majority (even if that be only a single director) of the remaining directors theretofore elected by the holders of the class or classes of stock which elected the director whose office shall have become vacant. To the extent permitted by applicable law, immediately upon any termination of the right of the holders of the Preferred Stock to vote as a class for directors as provided in paragraph (12) the term of office of the directors then in office so elected by the holders of the Preferred Stock shall terminate.

(16) If the amounts payable with respect to any obligations to retire shares of the Preferred Stock are not paid in full to the holders of the shares of all series with respect to which such obligations exist, the number of shares of each series to be retired shall be in proportion to the amount which would be payable to the holders of the shares of such series on account of such obligations if all amounts payable in respect of all such obligations were discharged in full.

(17) No holder of Preferred Stock as such shall have any preemptive or preferential right to purchase or subscribe to stock, obligations, warrants, rights to subscribe to stock or other securities of the Corporation of any class, whether now or hereafter authorized or issued.

(18) Except as may be required under the applicable statutes or may be set forth in the resolution or resolutions providing for the issue of any series adopted by the Board of Directors as hereinabove provided and except for the voting powers provided with respect to all shares of the Preferred Stock set forth above, no holder of Preferred Stock as such shall have any voting powers on any matters upon which stockholders of the Corporation have the right to vote.

(19) For the purpose hereof and of any resolution of the Board of Directors providing for the classification or reclassification of any shares of Preferred Stock or for the purpose of any certificate filed with the Republic of Panama (unless otherwise provided in any such resolution or certificate):

-11-

(a) The term “outstanding”, when used in reference to shares of stock, shall mean issued shares, excluding shares held by the Corporation and shares called for redemption funds for the redemption of which shall have been deposited in trust;

(b) The amount of dividends “accrued” on any share of Preferred Stock of any series as at any dividend date shall be deemed to be the amount of any unpaid dividends accumulated thereon to and including such dividend date, whether or not earned or declared, and the amount of dividends “accrued” on any share of Preferred Stock of any series as at any date other than a dividend date shall be calculated thereon to and including the last preceding dividend date, whether or not earned or declared, plus an amount equivalent to the pro rata portion of the periodic dividend with respect thereto at the annual dividend rate fixed for the shares of such series for the period after such last preceding dividend date to and including the date as of which the calculation is made;

(i) prior to the Preferred Stock either as to dividends or upon liquidation, if the holders of such class or classes shall be entitled to the receipt of dividends or of amounts distributable upon liquidation, dissolution or winding up, as the case may be, in preference or priority to the holders of the Preferred Stock;

(ii) on a parity with the Preferred Stock either as to dividends or upon liquidation, whether or not the dividend rates, dividend payment dates, or redemption or liquidation prices per share thereof be different from those of the Preferred Stock, if the holders of such class or classes of stock shall be entitled to the receipt of dividends or of amounts distributable upon liquidation, dissolution or winding up, as the case may be, in proportion to their respective dividend rates or liquidation prices, without preference or priority one over the other with respect to the holders of the Preferred Stock;

(iii) junior to the Preferred Stock either as to dividends or upon liquidation if the rights of the holders or such class or classes shall be subject or subordinate to the rights of the holders of the Preferred Stock in respect of the receipt of dividends or of amounts distributable upon liquidation, dissolution or winding up, as the case may be.

PART B. Provisions Relating to Common Stock

(1) At all times (subject to the special voting rights of the Preferred Stock pursuant to paragraph (12) of Part A) each holder of Common Stock of the Corporation shall be entitled to one vote for each share of such stock outstanding in the name of such holder on the books of the Corporation on the record date designated for the purpose of such vote.

(2) No holder of shares of Common Stock shall have, as such holder, any preemptive right to purchase or subscribe to stock, obligations, warrants, rights to subscribe to stock or other securities of the Corporation of any class, whether now or hereafter authorized or issued.

7. The number of directors constituting the entire Board of shall be such as shall be fixed from time to time by vote of a majority of the entire Board of Directors, provided, however, that the number of directors shall not be reduced so as to shorten the term of any director at the time in office, and provided further, that the number of directors constituting the entire Board of Directors shall be fourteen until otherwise fixed by a majority of the entire Board of Directors.

The Board of Directors shall be divided into three classes, respectively designated “Class I,” “Class II” and “Class III”, as nearly equal in number as the then total number of directors constituting the entire Board of Directors permits with the term of office of one class expiring each year. Whenever possible there shall be at least three (3) directors in each class. If the number of directors is reduced to seven (7) or eight (8), Class III shall be eliminated and the directors distributed between Classes I and II.

At the first special meeting of stockholders held after November 1, 1982 directors of the first class shall be elected to hold office for a term expiring at the next succeeding annual meeting, directors of the second class shall be elected to hold office for a term expiring at the second succeeding annual meeting and directors of the third class shall be elected to hold office for a term expiring at the third succeeding annual meeting. Subject to the provisions of Part A of Article 3, any vacancy in the Board of Directors for any reason, and any created directorships resulting from any increase in the number of directors, may be filled only by the Board of Directors, acting by a majority of the directors then in office, although less than a quorum, or by a sole remaining director, and any directors so chosen shall hold office until the next election of the class for which such directors shall have been chosen and until their successors shall be elected and qualified.

RESOLVED, that the Board of Directors of McDermott International, Inc. (the “Corporation”), pursuant to authority vested in it by the provisions of the Articles of Incorporation, as amended, of the Corporation, hereby authorizes the issue of a series of the Corporation’s Preferred Stock, $1.00 par value, twenty-five-million shares of which are authorized to be issued under the Corporation’s Articles of Incorporation, as amended (such twenty-five- million shares being hereinafter called the “Preferred Stock”), and hereby fixes the number, designation, preferences, rights and limitations thereof, all of which are expressed in currency of the United States of America and are in addition to those set forth in said Articles of Incorporation, as amended, as follows:

1. Designation. 100,000 shares of the Preferred Stock of the Corporation are hereby constituted as a series of the Preferred Stock designated as “Series A $10.00 Participating Preferred Stock” (hereinafter called “Series A Preferred Stock”). The Board of Directors is authorized, by resolutions duly adopted, to decrease from time to time but not increase the number of shares of Series A Preferred Stock. Shares of Series A Preferred Stock shall rank prior to the Corporation’s Common Stock (par value $1 per share) (“Common Stock”) with respect to the payment of dividends (except as provided in Section 2(b) below) and upon liquidation.

2. Dividends, Acquisitions of Junior or Series A Preferred Stock and Priority.

(a) Preferential dividends on the Series A Preferred Stock shall be at the rate of $10.00 per share per annum and such cumulative cash dividends thereon shall be payable, when and as declared by the Board of Directors, quarterly on the first day of January, April, July and October in each year, commencing on the first of such dates occurring more than 45 days after the original issuance of the Series A Preferred Stock. The initial quarterly preferential dividend payable with respect to each outstanding share of Series A Preferred Stock after the date of original issuance of such share shall be in an amount determined by multiplying $10.00 by a fraction, the numerator of which shall be the number of days between the date of issuance and the dividend payment date for such initial quarterly dividend (counting the date of issuance but not such dividend payment date) and the denominator of which shall be 365.

(b) In addition to the preferential dividend thereon, there shall be declared a dividend (a “participating Dividend”) on the Series A Preferred Stock whenever the declaration of a dividend on the Common Stock of the Corporation or on stock of the Corporation of any other class ranking junior to the Series A Preferred Stock (collectively “Junior Stock”) would (or a transaction deemed by this resolution to constitute the declaration of a dividend on Junior Stock would) increase the amount constituting Excess Dividends of the then current fiscal year determined pursuant to this resolution immediately after such declaration of a dividend or such transaction deemed to constitute the declaration of a dividend; and the Corporation shall not declare a dividend on Junior Stock or consummate a transaction deemed to constitute the declaration of a dividend on Junior Stock if the amount constituting Excess Dividends immediately after such declaration or transaction would be increased by reason of such declaration or transaction unless the Corporation simultaneously declares the Participating Dividend on Series A Preferred Stock required by this resolution by reason of such declaration or transaction with respect to Junior Stock.

-2-

Dividends. For the purposes of this resolution: (x) no dividend payable in shares of Junior Stock shall be treated as a dividend (y) any dividend payable in United States dollars shall be taken into account at the amount so payable and (z) any dividend payable in any other property (except stock described in item (x) above) and any payment in any transaction deemed to be a dividend shall be taken into account at the full fair value of such property stated in United States dollars on the day such dividend is declared or such payment is made.

Amounts deemed to be dividends. Any consideration given by the Corporation or an Affiliate (or by each in part) to purchase, redeem or retire any share of Junior Stock shall be deemed for the purposes of this resolution to be a dividend declared on Junior Stock in the amount of the full fair value of such consideration stated in United States dollars on the day such consideration is given.

Excess Dividends. For the purposes of this resolution the amount constituting Excess Dividends shall, at any time during any fiscal year, be the excess of:

(i) the aggregate of all the dividends previously declared on Junior Stock during that fiscal year plus the aggregate of all amounts deemed, pursuant to this resolution, to have been dividends previously declared on Junior Stock during that fiscal year; over

(ii) the amount determined by multiplying the total number of shares of Junior Stock outstanding immediately prior to any declaration of a dividend on Junior Stock or to any purchase, retirement or redemption deemed to be a dividend pursuant to this resolution by three dollars ($3.00).

Series A Participation. The Series A Participation at any time during any fiscal year shall, for purposes of this resolution, be determined as follows:

(i) The Participation Base shall be the amount of the Excess Dividends at that time divided by the number of shares of Junior Stock then outstanding.

(ii) The Participation Portion shall be the sum of

(a) 10% of the Participation Base;

(b) 10% of that part of the Participation Base in excess of one dollar ($1.00);

^© 20% of that part of the Participation Base in excess of two dollars ($2.00), and

(d) 40% of that part of the Participation Base in excess of three dollars ($3.00).

-3-

(iii) The Series A Participation at any time shall be the Participation Portion determined at that time multiplied by the number of shares of Junior Stock then outstanding.

Participating Dividend. The amount to be declared as a Participating Dividend at any time pursuant to this resolution shall be:

(i) an amount equal to the Series A Participation determined at that time pursuant to this resolution multiplied by a fraction the numerator of which is the number of shares of Series A Preferred Stock then outstanding and the denominator of which is one hundred thousand reduced by

(ii) an amount equal to the sum of all the Participating Dividends previously declared during that fiscal year on a single share of Series A Preferred Stock outstanding throughout that fiscal year multiplied by the number of shares of Series A Preferred Stock then outstanding.

Increase or decrease of money amounts. Each of the Amounts (one, two and three dollars) to be employed originally pursuant to this resolution to determine the amount to be declared as a Participating Dividend on Series A Preferred Stock at any time shall, from time to time, be increased or decreased if, when and to the extent required by this paragraph.

(i) Each such Amount shall be increased (immediately after any declaration of a dividend on Junior Stock or any purchase, retirement or redemption deemed to be a dividend pursuant to this resolution) to reflect any purchase, redemption or retirement of any share of Junior Stock by the Corporation or an Affiliate. Any such increase shall be reflected by multiplying such Amount by a fraction the numerator of which shall be the number of shares of Junior Stock outstanding immediately before such purchase, redemption or retirement and the denominator of which shall be the number of shares of Junior Stock outstanding immediately thereafter.

(ii) Each such Amount shall be decreased (immediately thereafter) to reflect the issuance or sale of any share of Junior Stock by the Corporation or an Affiliate in a transaction in which the Corporation or such Affiliate does not (or the two together do not) receive, in exchange for such share of Junior Stock, money or other property in an amount equal to or greater than the full fair value of such share of Junior Stock stated in United States dollars at the date such share is issued or old, regardless whether such issue or sale occurs through the distribution of Junior Stock as a dividend on stock (or upon a stock split) without the receipt of any consideration or occurs through the issue or sale of Junior Stock for a consideration which is, in the aggregate, of lesser value than the full fair value of the Junior Stock issued or sold at the time of such issue or sale. Any such decrease shall be reflected by multiplying such amount by a fraction the numerator of which is the number of shares of Junior Stock outstanding immediately before such issue or sale and the denominator of which is

(a) the number of shares of Junior Stock outstanding immediately after such issue or sale, less

-4-

(b) that number of shares of Common Stock of the Corporation the aggregate value of which (at the date of such issue or sale) is equal to the consideration received upon such issue or sale.

For the purpose of determining any increase or decrease in an Amount pursuant
to this paragraph:

(iii) a share of Junior Stock held by an Affiliate shall not be treated as a share of stock outstanding.

(iv) any consideration received by the Corporation or an Affiliate upon the issue or sale of a share of Junior Stock to the Corporation or an Affiliate shall not be treated as consideration received upon the issue or sale of a share of Junior Stock.

No increase or decrease of an Amount pursuant to this paragraph shall be made if such increase or decrease would be less than 5% of that Amount as last previously increased or decreased pursuant to this paragraph. The previous sentence notwithstanding, any Amount (as last increased or decreased pursuant to this paragraph) shall be increased or decreased as herein provided when the net aggregate of all increases and decreases in such Amount which would have been made but for the preceding sentence since the last increase or decrease of such Amount pursuant to this paragraph equals 5% or more of such Amount as last increased or decreased pursuant to this paragraph.

Affiliate. For the purposes of this resolution, any corporation, partnership, trust, joint venture or other person shall be considered an Affiliate if

(i) such person holds 25% or more in value of all the stock of the Corporation;

(ii) the Corporation and any Affiliate or Affiliates hold, between them and in the aggregate, 25% or more in value of all the stock (or comparable interests in the assets or earnings) of such person, or

(iii) 25% or more in value of all the stock of the Corporation and 25% or more in value of all the stock (or comparable interests in the assets or earnings of such person) are held (directly or indirectly) by the same person or are, between them and in the aggregate, held (directly or indirectly) held by the same group of persons acting in concert with respect to such holdings.

(c) Except for Participating Dividends (to the extent declared pursuant to Section 2(b) hereof), no dividend shall be declared or paid on any shares of Series A Preferred Stock or any other series of the Preferred Stock in respect of any dividend period unless there shall have been declared or paid on all shares than outstanding of Series A Preferred Stock and any other series of the Preferred Stock like dividends for all dividend periods coinciding with or terminating within such dividend period, ratably in proportion to the respective fixed dividend rates established for the Series A Preferred Stock and such other series of the Preferred Stock.

-5-

(d) The Corporation shall not redeem or purchase or otherwise acquire for value shares of Common Stock or any other class of stock or series thereof ranking junior to the Series A Preferred Stock as to preferential dividends or upon liquidation if at the time of making such redemption, purchase or other acquisitions the Corporation shall be in default with respect to any dividends payable on, or any obligation to redeem or retire, shares of Series A Preferred Stock.

(e) Fixed cash dividends upon shares of Series A Preferred Stock shall commence to accrue and be cumulative from the date of issue thereof. Accumulated dividends on shares of Series A Preferred Stock shall not bear interest.

Stock shall be entitled to its proportional share of such aggregate number of
votes.

5. Liquidation Rights.

(b) Neither the merger nor consolidation of the Corporation into or with any other corporation, nor the merger or consolidation of any other corporation into or with the Corporation, nor a sale, transfer or lease of all or any part of the assets of the

(d) Subject to the provisions of Section 5(a) hereof, no payment on account of such liquidation, dissolution or winding up of the Corporation shall be made to the holders of any class or series of stock ranking on a parity with the Series A Preferred Stock in respect of the distribution of assets, unless there shall likewise be paid at the same time to the holders of shares of Series A Preferred Stock like amounts, ratably, in proportion to the full distributive amounts which they and the holders of such other class or series of stock are entitled.
