The address of the Corporation’s registered office in the State of Delaware is Corporation Trust Center, 1209 Orange Street, in the City of Wilmington, County of New Castle, Delaware 19801. The name of its registered agent at such address is The Corporation Trust Company.

The nature of the business or purposes to be conducted or promoted by the Corporation is to engage in any lawful act or activity for which corporations may now or hereafter be organized under the General Corporation Law of the State of Delaware, as amended from time to time (the “General Corporation Law”).

A. The Corporation is authorized to issue two classes of shares of capital stock to be designated, respectively, “Preferred Stock” and “Common Stock.” The total number of shares of capital stock which the Corporation shall have authority to issue is 70,000,000, of which 10,000,000 shares shall be Preferred Stock at the par value of $.01 per share and 60,000,000 shares shall be Common Stock at the par value of $.01 per share.

B. The Preferred Stock may be divided into and issued in one or more series. The Board of Directors is hereby vested with the authority from time to time to establish and designate such series and, within the limitations prescribed by law, to fix and determine the designations, powers, preferences, and relative, participating, optional or other special rights, and qualifications, limitations and restrictions of any series so established.

In the event of any voluntary or involuntary liquidation, dissolution or winding up of the Corporation, the holders of Common Stock shall share ratably in the assets of the Corporation remaining after payment of the preferential amounts required to be paid to holders of Preferred Stock.

A. The business and affairs of the Corporation shall be managed by or under the direction of the Board of Directors, which shall consist of not less than ten nor more than fifteen directors, the exact number of directors to be determined from time to time by resolution adopted by the affirmative vote of a majority of the directors then in office.

B. In addition to the powers and authority expressly conferred upon them by the General Corporation Law or by this Certificate of Incorporation or the Bylaws of the Corporation, the directors are hereby empowered to exercise all such powers and do all such acts and things as may be exercised or done by the Corporation. At all meetings of the Board of Directors, each director shall have one vote, and all questions shall be decided by a majority of the directors present at each such meeting, provided, however, that certain matters, as provided hereinbelow or in the Bylaws, shall be decided by a majority of the directors then in office or by the Continuing Directors (defined below).

C. Subject to the rights of the holders of any class or series of Preferred Stock and to the requirements of law, newly created directorships resulting from any increase in the authorized number of directors or any vacancies resulting from death, resignation, retirement, disqualification, removal from office or other cause may be filled only by a majority vote of the directors then in office, though less than a quorum, and directors so chosen shall hold office for a term expiring at the next annual meeting of stockholders and until such directors’ successors shall have been duly elected and qualified.

A. Any action required or permitted to be taken by the stockholders of the Corporation may be effected only at a duly noticed and called annual or special meeting of stockholders of the Corporation and may not be effected by consent in writing of such stockholders. Special meetings of the stockholders of the Corporation may be called only by the Chairman of the Board or by the Board of Directors pursuant to a resolution adopted by a majority of the directors then in office.

B. At all elections of directors of the Corporation, each stockholder shall be entitled to as many votes as shall equal the number of votes which (except for this provision for cumulative voting) he (or she) would be entitled to cast for the election of directors with respect to his shares of stock multiplied by the number of directors to be elected by him, and he may cast all of such votes for a single director or may distribute such votes for any two or more of such directors as he may see fit.

A. In addition to any affirmative vote of the holders of any particular class or series of the capital stock of the Corporation that may be required by law or otherwise and in addition to any affirmative vote of the directors of the Corporation that may be required by law or otherwise, the Corporation shall not engage in a Business Combination (defined below) unless and until the following conditions have been satisfied:

1. The Business Combination must be approved by either (i) a majority of the Continuing Directors, provided that this condition shall not be capable of satisfaction unless there are at least three Continuing Directors, or (ii) the affirmative vote of the holders of at least two-thirds of the total voting power of the then-outstanding shares of Voting Stock, excluding Voting Stock of which Interested Stockholders are the Beneficial Owners (as such terms are defined below), voting together as a single class; and

2. If the Business Combination is approved by a majority of the Continuing Directors but not by the affirmative vote of the stockholders described above in Article VII.A.1(ii), the following conditions must also be satisfied in the case of a Business Combination that involves the payment of cash or other consideration to the stockholders of the Corporation in their capacity as stockholders:

(i) The consideration to be received by holders of shares of a particular class or series of outstanding capital stock must be in cash or in the same form as the Interested Stockholder involved in the Business Combination has previously paid for shares of such class or series of capital stock. If the Interested Stockholder has paid for shares of any class or series of capital stock with varying forms of consideration, the form of consideration to be received per share by holders of shares of such class or series of capital stock shall be either cash or the form used to acquire the largest number of shares of such class or series previously acquired by the Interested Stockholder; and

(ii) The cash or Fair Market Value (defined below) of other consideration to be received per share by the holders of each class or series of capital stock of the Corporation in the Business Combination must not be less than the highest per share price (including brokerage commissions and/or soliciting dealers’ fees) paid by the Interested Stockholder in acquiring any shares of such class or series, respectively, within the twenty-four months preceding the date of consummation of the Business Combination (appropriately adjusted for any stock split, stock dividend, combination of shares or similar event).

1. “Affiliate” or “Associate” shall have the respective meanings ascribed to such terms in Rule 12b-2 under the Exchange Act (defined below).

2. A Person (defined below) is the “Beneficial Owner” of any and all Voting Stock:

(iii) Which are beneficially owned, directly or indirectly, within the meaning of Rule 13d-3 under the Exchange Act, by any other Person with which such Person or any of its Affiliates or Associates has any agreement, arrangement or understanding for the purpose of acquiring, holding, voting or disposing of any shares of Voting Stock.

(iv) The issuance or transfer to any Interested Stockholder by the Corporation or any Subsidiary (in one transaction or a series of transactions) of any securities of the Corporation or any Subsidiary having an aggregate Fair Market Value of $5,000,000 or more, except pursuant to a dividend, distribution, exchange offer or purchase offer made by the Corporation on a pro rata basis to all holders of a class or series of its capital stock and which does not have the effect, directly or indirectly and in one transaction or a series of transactions, of increasing by more than one percent the proportionate share of the outstanding shares of any class of equity or convertible securities of the Corporation or any Subsidiary of which any Interested Stockholder is the Beneficial Owner; or

(v) The adoption of any plan or proposal for the liquidation or dissolution of the Corporation proposed by or on behalf of any Interested Stockholder; or

(vi) Any reclassification of securities (including any reverse stock split or recapitalization of the Corporation), any merger or consolidation of the Corporation with any of its Subsidiaries or any other transaction (whether or not with or into or otherwise involving any Interested Stockholder) which has the effect, directly or indirectly and in one transaction or a series of transactions, of increasing by more than one percent the proportionate share of the outstanding shares of any class of equity or convertible securities of the Corporation or any Subsidiary of which any Interested Stockholder is the Beneficial Owner.

Automated Quotations System or any other quotation reporting system then in use, or if no such quotations are available, the fair market value on the date in question of a share of such stock or other security as determined by the Board of Directors in good faith, and (ii) in the case of property other than stock or other securities, the fair market value of such property on the date in question as determined by the Board of Directors in good faith.

C. The Board of Directors, when evaluating any proposed transaction that would result in a Person becoming an Interested Stockholder, or in an Interested Stockholder increasing its ownership of capital stock of the Corporation, or any transaction with any other party, whether or not such other party is an Interested Stockholder, that would constitute a Business Combination if the other party to the transaction were or would thereby become an Interested Stockholder, may, to the fullest extent permitted by law, give due consideration to the independence and integrity of the Corporation’s operations, and the effects of the transaction on the stockholders, employees, customers and other constituents of the Corporation. Nothing contained in this Article VII shall be construed as relieving any Interested Stockholder from any fiduciary obligation imposed by law.

No director of the Corporation shall be personally liable to the Corporation or its stockholders for monetary damages for any breach of fiduciary duty by such director as a director. Notwithstanding the foregoing sentence, a director shall be liable to the extent provided by applicable law (i) for any breach of the director’s duty of loyalty to the Corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) pursuant to Section 174 of the General Corporation Law, or (iv) for any transaction from which such director derived an improper personal benefit.

be limited or eliminated to the fullest extent permitted by the General Corporation Law, as so amended.

A. Subject to the provisions hereof, the Corporation reserves the right at any time, and from time to time, to amend, or repeal any provision contained in this Certificate of Incorporation in the manner now or hereafter prescribed by law, and all rights, preferences and privileges of whatsoever nature conferred upon stockholders, directors and any other persons pursuant to this Certificate of Incorporation are granted subject to this reservation.

B. In addition to any affirmative vote of the holders of any particular class or series of the capital stock of the Corporation that may be required by law or otherwise and in addition to any affirmative vote of the directors of this Corporation that may be required by law or otherwise, any amendment or repeal of any provision of this Certificate of Incorporation shall require the affirmative vote of the holders of at least two-thirds of the total voting power of the then-outstanding shares of Voting Stock, voting together as a single class, provided, however, that any amendment or repeal of any provision of Article VII hereof (Business Combinations) shall require the affirmative vote of the holders of at least two-thirds of the total voting power of the then-outstanding shares of Voting Stock, excluding Voting Stock of which Interested Stockholders are the Beneficial Owners, voting together as a single class.

C. The Board of Directors shall have concurrent power with the stockholders to adopt, amend or repeal the Bylaws of this Corporation, provided, however, that no provision of the Bylaws may be adopted, amended or repealed if the effect thereof would be to modify or permit the circumvention of any provision of this Certificate of Incorporation. Any adoption, amendment or repeal of the Bylaws by the Board of Directors shall require the approval of a majority of the directors then in office.

By		/s/ George D. Leal
		George D. Leal
		Chairman of the Board and Chief Executive Officer

Dames & Moore, Inc., a corporation organized and existing under the General Corporation Law of the State of Delaware (hereinafter called the “Corporation”), hereby certifies that the following resolution was adopted by the Board of Directors of the Corporation as required by Section 151 of the General Corporation Law of the State of Delaware at a meeting duly called and held on March 14, 1997.

RESOLVED, that pursuant to the authority granted to and vested in the Board of Directors of this Corporation (hereinafter called the “Board of Directors” or the “Board”) in accordance with the provisions of the Certificate of Incorporation, the Board of Directors hereby creates a series of Preferred Stock, par value $0.01 per share (the “Preferred Stock”), of the Corporation and hereby states the designation and number of shares, and fixes the relative rights, preferences, and limitations thereof as follows:

Section 1. Designation and Amount. The shares of such series shall be designated as “Series A Junior Participating Preferred Stock” (the “Series A Preferred Stock”) and the number of shares constituting the Series A Preferred Stock shall be 135,000. Such number of shares may be increased or decreased by resolution of the Board of Directors; provided, that no decrease shall reduce the number of shares of Series A Preferred Stock to a number less than the number of shares then outstanding plus the number of shares reserved for issuance upon the exercise of outstanding options, rights or warrants or upon the conversion of any outstanding securities issued by the Corporation convertible into Series A Preferred Stock.

(A) Subject to the rights of the holders of any shares of any series of Preferred Stock (or any similar stock) ranking prior and superior to the Series A Preferred Stock with respect to dividends, the holders of shares of Series A Preferred Stock, in preference to the holders of Common Stock, par value $0.01 per share (the “Common Stock”), of the Corporation, and of any other junior stock, shall be entitled to receive, when, as and if declared by the Board of Directors out of funds legally available for the purpose, quarterly dividends payable in cash on or about the first day of March, June, September and December in each year (each such date being referred to herein as a “Quarterly Dividend Payment Date”), commencing on the first Quarterly Dividend Payment Date after the first issuance of a share or fraction of a share of Series A Preferred Stock, in an amount per share (rounded to the nearest cent) equal to the greater of (a) $ 1.00 or (b) subject to the provision for adjustment hereinafter set forth, 200 times the aggregate per share amount of all cash dividends, and 200 times the aggregate per share amount (payable in kind) of all non-cash dividends or other distributions, other than a dividend payable in shares of Common Stock or a subdivision of the outstanding shares of Common Stock (by reclassification or otherwise), declared on the Common Stock since the immediately preceding Quarterly Dividend Payment Date, or, with respect to the first Quarterly Dividend Payment Date, since the first issuance of any share or fraction of a share of Series A Preferred Stock. In the event the Corporation shall at any time after the date on which the Preferred Stock Purchase Rights of the Corporation are declared by the Board of Directors (the “Rights Declaration Date”) declare or pay any dividend on the Common Stock payable in shares of Common Stock, or effect a subdivision, combination or consolidation of the outstanding shares of Common Stock (by reclassification or otherwise than by payment of a dividend in shares of Common Stock) into a greater or lesser number of shares of Common Stock, then in each such case the amount to which holders of shares of Series A Preferred Stock were entitled immediately prior to such event under clause (b) of the preceding sentence shall be adjusted by multiplying such amount by a fraction, the numerator of which is the number of shares of Common Stock outstanding immediately after such event and the denominator of which is the number of shares of Common Stock that were outstanding immediately prior to such event.

(B) The Corporation shall declare a dividend or distribution on the Series A Preferred Stock as provided in paragraph (A) of this Section 2 immediately after it declares a dividend or distribution on the Common Stock (other than a dividend payable in shares of Common Stock); provided that, in the event no dividend or distribution shall have been declared on the Common Stock during the period between any Quarterly Dividend Payment Date and the next subsequent Quarterly Dividend Payment Date, a dividend of $1.00 per share on the Series A Preferred Stock shall nevertheless be payable on such subsequent Quarterly Dividend Payment Date.

(C) Dividends shall begin to accrue and be cumulative on outstanding shares of Series A Preferred Stock from the Quarterly Dividend Payment Date next preceding the date of issue of such shares, unless the date of issue of such shares is prior to the record date for the first Quarterly Dividend Payment Date, in which case dividends on such shares shall begin to accrue from the date of issue of such shares, or unless the date of issue is a Quarterly Dividend Payment Date or is a date after the record date for the determination of holders of shares of Series A Preferred Stock entitled to receive a quarterly dividend and before such Quarterly Dividend Payment Date, in either of which events such dividends shall begin to accrue and be cumulative from such Quarterly Dividend Payment Date. Accrued but unpaid dividends shall not bear interest. Dividends paid on the shares of Series A Preferred Stock in an amount less than the total amount of such dividends at the time accrued and payable on such shares shall be allocated pro rata on a share-by-share basis among all such shares at the time outstanding. The Board of Directors may fix a record date for the determination of holders of shares of Series A Preferred Stock entitled to receive payment of a dividend or distribution declared thereon, which record date shall be not more than 60 days prior to the date fixed for the payment thereof.

Section 3. Voting Rights. The holders of shares of Series A Preferred Stock shall have the following voting rights:

(A) Subject to the provision for adjustment hereinafter set forth, each share of Series A Preferred Stock shall entitle the holder thereof to 200 votes on all matters submitted to a vote of the stockholders of the Corporation. In the event the Corporation shall at any time after the Rights Declaration Date declare or pay any dividend on the Common Stock payable in shares of Common Stock, or effect a subdivision, combination or consolidation of the outstanding shares of Common Stock (by reclassification or otherwise than by payment of a dividend in shares of Common Stock) into a greater or lesser number of shares of Common Stock, then in each such case the number of votes per share to which holders of shares of Series A Preferred Stock were entitled immediately prior to such event shall be adjusted by multiplying such number by a fraction, the numerator of which is the number of shares of Common Stock outstanding immediately after such event and the denominator of which is the number of shares of Common Stock that were outstanding immediately prior to such event.

(B) Except as otherwise provided herein, in any other Certificate of Designations creating a series of Preferred Stock or any similar stock, or by law, the holders of shares of Series A Preferred Stock and the holders of shares of Common Stock and any other capital stock of the Corporation which may from time to time be accorded such voting right shall vote together as one class on all matters submitted to a vote of stockholders of the Corporation.

(C) (i) If at any time dividends on any Series A Preferred Stock shall be in arrears in an amount equal to six (6) quarterly dividends thereon, the occurrence of such

contingency shall mark the beginning of a period (herein called a “default period”) which shall extend until such time when all accrued and unpaid dividends for all previous quarterly dividend periods and for the current quarterly dividend period on ail shares of Series A Preferred Stock then outstanding shall have been declared and paid or set apart for payment. During each default period, the holders of Series A Preferred Stock, voting as a class, shall have the right to elect two (2) directors.

(ii) During any default period, such voting right of the holders of Series A Preferred Stock may be exercised initially at a special meeting called pursuant to subparagraph (iii) of this Section 3(C) or at any annual meeting of stockholders, and thereafter at annual meetings of stockholders, provided that such voting right shall not be exercised unless the holders of ten percent (10%) in number of shares of Series A Preferred Stock outstanding shall be present in person or by proxy, The absence of a quorum of the holders of Common Stock shall not affect the exercise by the holders of Series A Preferred Stock of such voting right. At any meeting at which the holders of Series A Preferred Stock shall exercise such voting right initially during an existing default period, they shall have the right, voting as a class, to elect directors to fill such vacancies, if any, in the Board of Directors as may then exist up to two (2) directors or, if such right is exercised at an annual meeting, to elect two (2) directors. If the number which may be so elected at any special meeting does not amount to the required number, the holders of the Series A Preferred Stock shall have the right to make such increase in the number of directors as shall be necessary to permit the election by them of the required number. After the holders of the Series A Preferred Stock shall have exercised their right to elect directors in any default period and during the continuance of such period, the number of directors shall not be increased or decreased except by vote of the holders of Series A Preferred Stock as herein provided or pursuant to the rights of any equity securities ranking senior to or pari passu with the Series A Preferred Stock.

(iii) Unless the holders of Series A Preferred Stock shall, during an existing default period, have previously exercised their right to elect directors, the Board of Directors may order, or any stockholder or stockholders owning in the aggregate not less than ten percent (10%) of the total number of shares of Series A Preferred Stock outstanding may request, the calling of a special meeting of the holders of Series A Preferred Stock, which meeting shall thereupon be called by the President, a Vice President or the Secretary of the Corporation. Notice of such meeting and of any annual meeting at which holders of Series A Preferred Stock are entitled to vote pursuant to this paragraph (C)(iii) shall be given to each holder of record of Series A Preferred Stock by mailing a copy of such notice to him at his last address as the same appears on the books of the Corporation. Such meeting shall be called for a time not earlier than 20 days and not later than 60 days after such order or request or in default of the calling of such meeting within 60 days after such order or request, such meeting may be called on similar notice

by any stockholder or stockholders owning in the aggregate not less than ten percent (10%) of the total number of shares of Series A Preferred Stock outstanding. Notwithstanding the provisions of this paragraph (C)(iii), no such special meeting shall be called during the period within 60 days immediately preceding the date fixed for the next annual meeting of the stockholders.

(iv) In any default period, the holders of Common Stock and other classes of stock of the Corporation if applicable, shall continue to be entitled to elect the whole number of directors until the holders of Series A Preferred Stock shall have exercised their right to elect two (2) directors voting as a class, after the exercise of which right (x) the directors so elected by the holders of Series A Preferred Stock shall continue in office until their successors shall have been elected by such holders or until the expiration of the default period, and (y) any vacancy in the Board of Directors may (except as provided in paragraph (C)(iii) of this Section 3) be filled by vote of a majority 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. References in this paragraph (C) to directors elected by the holders of a particular class or classes of stock shall include directors elected by such directors to fill vacancies as provided in clause (y) of the foregoing sentence.

(v) Immediately upon the expiration of a default period, (x) the right of the holders of Series A Preferred Stock as a class to elect directors shall cease, (y) the term of any directors elected by the holders of Series A Preferred Stock as a class shall terminate, and (z) the number of directors shall be such number as may be provided for in the certificate of incorporation or bylaws irrespective of any increase made pursuant to the provisions of paragraph (C)(ii) of this Section 3 (such number being subject, however, to change thereafter in any manner provided by law or in the certificate of incorporation or bylaws). Any vacancies in the Board of Directors effected by the provisions of clauses (y) and (z) in the preceding sentence may be filled by a majority of the remaining directors.

(D) Except as set forth herein, or as otherwise provided by law, holders of Series A Preferred Stock shall have no special voting rights and their consent shall not be required (except to the extent they are entitled to vote with holders of Common Stock and other classes of stock of the Corporation, if applicable, as set forth herein) for taking any corporate action.

(A) Whenever quarterly dividends or other dividends or distributions payable on the Series A Preferred Stock as provided in Section 2 are in arrears, thereafter and until all accrued and unpaid dividends and distributions, whether or not declared, on shares

of Series A Preferred Stock outstanding shall have been paid in full, the Corporation shall not:

(i) declare or pay dividends on, make any other distributions on, redeem on or purchase or otherwise acquire for consideration any shares of stock ranking junior (either as to dividends or upon liquidation, dissolution or winding up) to the Series A Preferred Stock;

(ii) declare or pay dividends on, or make any other distributions on any shares of stock ranking on a parity (either as to dividends or upon liquidation, dissolution or winding up) with the Series A Preferred Stock, except dividends paid ratably on the Series A Preferred Stock and all such parity stock on which dividends are payable or in arrears in proportion to the total amounts to which the holders of all such shares are then entitled;

(iii) redeem or purchase or otherwise acquire for consideration shares of any stock ranking on a parity (either as to dividends or upon liquidation, dissolution or winding up) with the Series A Preferred Stock, provided that the Corporation may at any time redeem, purchase or otherwise acquire shares of any such on a parity stock in exchange for shares of any stock of the Corporation ranking junior (either as to dividends or upon dissolution, liquidation or winding up) to the Series A Preferred Stock; or

(iv) purchase or otherwise acquire for consideration any shares of Series A Preferred Stock, or any shares of stock ranking on a parity with the Series A 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 such shares upon such terms as the Board of Directors, after consideration of the respective annual dividend rates and other relative rights and preferences of the respective series and classes, shall determine in good faith will result in fair and equitable treatment among the respective series or classes.

(B) The Corporation shall not permit any subsidiary of the Corporation to purchase or otherwise acquire for consideration any shares of stock of the Corporation unless the Corporation could, under paragraph (A) of this Section 4, purchase or otherwise acquire such shares at such time and in such manner.

Section 5. Reacquired Shares. Any shares of Series A Preferred Stock purchased or otherwise acquired by the Corporation in any manner whatsoever shall be retired and cancelled promptly after the acquisition thereof. All such shares shall upon their cancellation become authorized but unissued shares of Preferred Stock and may be reissued as part of a new series of Preferred Stock to be created by resolution or resolutions of the Board of Directors, subject to the conditions and restrictions on issuance set forth herein, in the Corporation’s Certificate

of Incorporation, or in any other Certificate of Designations creating a series of Preferred Stock or any similar stock or as otherwise required by law.

Section 6. Liquidation, Dissolution or Winding Up. (A) Upon any liquidation (voluntary, or otherwise), dissolution or winding up of the Corporation, no distribution shall be made (1) to the holders of shares of stock ranking junior (either as to dividends or upon liquidation, dissolution or winding up) to the Series A Preferred Stock unless, prior thereto, the holders of shares of Series A Preferred Stock shall have received $100 per share, plus an amount equal to accrued and unpaid dividends and distributions thereon, whether or not declared, to the date of such payment (the “Liquidation Preference”). Following the payment of the full amount of the Liquidation Preference, no additional distributions shall be made to the holders of shares of Series A Preferred Stock unless, prior thereto, the holders of shares of Common Stock shall have received an amount per share (the “Common Adjustment”) equal to the quotient obtained by dividing (i) the Liquidation Preference by (ii) 200 (as appropriately adjusted as set forth in subparagraph (C) below to reflect such events as stock splits, stock dividends and recapitalizations with respect to the Common Stock) (such number in clause (ii), the “Adjustment Number”). Following the payment of the full amount of the Liquidation Preference and the Common Adjustment in respect of all outstanding shares of Series A Preferred Stock and Common Stock, respectively, holders of Series A Preferred Stock and holders of shares of Common Stock shall receive their ratable and proportionate share of the remaining assets to be distributed in the ratio of the Adjustment Number to 1 with respect to such Series A Preferred Stock and Common Stock, on a per share basis, respectively.

(B) In the event, however, that there are not sufficient assets available to permit payment in full of the Liquidation Preference and the liquidation preferences of all other series of stock, if any, which rank on a parity with the Series A Preferred Stock, then such remaining assets shall be distributed ratably to the holders of such parity shares in proportion to their respective liquidation preferences. In the event, however, that there are not sufficient assets available to permit payment in full of the Common Adjustment, then such remaining assets shall be distributed ratably to the holders of Common Stock.

(C) In the event the Corporation shall at any time after the Rights Declaration Date declare or pay any dividend on the Common Stock payable in shares of Common Stock, or effect a subdivision, combination or consolidation of the outstanding shares of Common Stock (by reclassification or otherwise than by payment of a dividend in shares of Common Stock) into a greater or lesser number of shares of Common Stock, then in each such case the Adjustment Number in effect immediately prior to such event shall be adjusted by multiplying such Adjustment Number by a fraction, the numerator of which is the number of shares of Common Stock outstanding immediately after such event and the denominator of which is the number of shares of Common Stock that were outstanding immediately prior to such event.

Section 7. Consolidation, Merger, etc. In case the Corporation shall enter into any consolidation, merger, combination or other transaction in which the shares of Common Stock are exchanged for or changed into other stock or securities, cash and/or any other property, then in any such case each share of Series A Preferred Stock shall at the same time be similarly exchanged or changed into an amount per share, subject to the provision for adjustment hereinafter set forth, equal to 200 times the aggregate amount of stock, securities, cash and/or any other property (payable in kind), as the case may be, into which or for which each share of Common Stock is changed or exchanged. In the event the Corporation shall at any time after the Rights Declaration Date declare or pay any dividend on the Common Stock payable in shares of Common Stock, or effect a subdivision, combination or consolidation of the outstanding shares of Common Stock (by reclassification or otherwise than by payment of a dividend in shares of Common Stock) into a greater or lesser number of shares of Common Stock, then in each such case the amount set forth in the preceding sentence with respect to the exchange or change of shares of Series A Preferred Stock shall be adjusted by multiplying such amount by a fraction, the numerator of which is the number of shares of Common Stock outstanding immediately after such event and the denominator of which is the number of shares of Common Stock that were outstanding immediately prior to such event.

Section 8. Ranking. The Series A Preferred Stock shall rank junior to all other series of the Corporation’s Preferred Stock as to the payment of dividends and the distribution of assets, unless the terms of any such series shall provide otherwise.

Section 9. Amendment. The Certificate of Incorporation of the Corporation shall not be amended in any manner which would materially alter or change the powers, preferences or special rights of the Series A Preferred Stock so as to affect them adversely without the affirmative vote of the holders of a majority or more of the outstanding shares of Series A Preferred Stock, voting together as a single class.

Section 10. Fractional Shares. Series A Preferred Stock may be issued in fractions of a share which, shall entitle the holder, in proportion to such holder’s fractional shares, to exercise voting rights, receive dividends, participate in distributions and to have the benefit of all other rights of holders of Series A Preferred Stock.

IN WITNESS WHEREOF, this Certificate of Designations is executed on behalf of the Corporation by its Executive Vice President this 28th day of March, 1997.

The purpose of this corporation is to engage in any lawful act or activity for which a corporation may be organized under the General Corporation Law of the State of Delaware.

1. Directors shall be elected at each annual meeting of stockholders to hold office until the next annual meeting. Each director shall hold office either until the expiration of the term for which elected or appointed and until a successor has been elected and qualified, or until such director’s death, resignation or removal. No decrease in the number of directors constituting the Board of Directors shall shorten the term of any incumbent director.

2. No person entitled to vote at an election for directors may cumulate votes to which such person is entitled, unless, at the time of such election, the corporation is subject to Section 2115(b) of the California General Corporation Law (“CGCL”) During such time or times that the corporation is subject to Section 2115(b) of the CGCL, every stockholder entitled to vote at an election for directors may cumulate such stockholder’s votes and give one candidate a number of votes equal to the number of directors to be elected multiplied by the number of votes to which such stockholder’s shares are otherwise entitled, or distribute the stockholder’s votes on the same principle among as many candidates as such stockholder thinks fit. No stockholder, however, shall be entitled to so cumulate such stockholder’s votes unless (a) the names of such candidate or candidates have been placed in nomination prior to the voting and (b) the stockholder has given notice at the meeting, prior to the voting, of such stockholder’s intention to cumulate such stockholder’s votes. If any stockholder has given proper notice to cumulate votes, all stockholders may cumulate their votes for any candidates who have been

properly placed in nomination. Under cumulative voting, the candidates receiving the highest number of votes, up to the number of directors to be elected, are elected.

1. During such time or times that the corporation is subject to Section 2115(b) of the CGCL, the Board of Directors or any individual director may be removed from office at any time without cause by the affirmative vote of the holders of at least a majority of the outstanding shares entitled to vote on such removal; provided, however, that unless the entire Board is removed, no individual director may be removed when the votes cast against such director’s removal, or not consenting in writing to such removal, would be sufficient to elect that director if voted cumulatively at an election which the same total number of votes were cast (or, if such action is taken by written consent, all shares entitled to vote were voted) and the entire number of directors authorized at the time of such director’s most recent election were then being elected.

2. At any time or times that the corporation is not subject to Section 2115(b) of the CGCL and subject to any limitations imposed by law, Section B.1 above shall not apply and the Board of Directors or any director may be removed from office at any time (a) with cause by the affirmative vote of the holders of a majority of the voting power of all then-outstanding shares of voting stock of the corporation entitled to vote at an election of directors or (b) without cause by the affirmative vote of the holders of sixty-six and two-thirds percent (66 2/3 %) of the voting power of all then-outstanding shares of voting stock of the corporation, entitled to vote at an election of directors.

A. The management of the business and the conduct of the affairs of the corporation shall be vested in its Board of Directors. The number of directors which shall constitute the whole Board of Directors shall be fixed by the Board of Directors in the manner provided in the Bylaws.

B. Subject to paragraph (h) of Section 43 of the Bylaws, the Bylaws may be altered or amended or new Bylaws adopted by the stockholders entitled to vote. The Board of Directors shall also have the power to adopt, amend or repeal Bylaws.

A. The liability of the directors for monetary damages shall be eliminated to the fullest extent permitted under applicable law.

B. This corporation is authorized to provide indemnification of agents (as defined in Section 317 of the CGCL) for breach of duty to the corporation and its stockholders through bylaw provisions or through agreements with the agents, or through stockholder resolutions, or

otherwise, in excess of the indemnification otherwise permitted by Section 317 of the CGCL, subject, at any time or times that the corporation is subject to Section 2115(b) of the CGCL, to the limits on such excess indemnification set forth in Section 204 of the CGCL.

C. Any repeal or modification of this Article VI shall be prospective and shall not affect the rights under this Article VI in effect at the time of the alleged occurrence of any act or omission to act giving rise to liability or indemnification.

The corporation reserves the right to amend, alter, change or repeal any provision contained in this Certificate of Incorporation, in the manner now or hereafter prescribed by statute, and all rights conferred upon the stockholders herein are granted subject to this reservation.

2. The registered office of the corporation within the State of Delaware is hereby changed to Corporation Trust Center, 1209 Orange Street, City of Wilmington, County of New Castle.

3. The registered agent of the corporation within the State of Delaware is hereby changed to The Corporation Trust Company, the business office of which is identical with the registered office of the corporation as hereby changed.

4. The corporation has authorized the changes hereinbefore set forth by resolution of its Board of Directors.
