OF 
 
ONEOK, INC. 
 
PURSUANT TO SECTION 1032 OF THE 
GENERAL CORPORATION ACT OF THE STATE OF
OKLAHOMA 
 
ONEOK, INC., an Oklahoma corporation
(the “Corporation”), does hereby certify that the Board of Directors of the Corporation duly adopted the following resolution, at a meeting duly convened and held on January 9, 2003, in respect of a series of Preferred Stock, par
value $0.01 per share, of the Corporation, pursuant to authority conferred upon the Board by Article Fourth of the Certificate of Incorporation of the Corporation and in accordance with Section 1032 of the General Corporation Act of the State of
Oklahoma: 
 
BE IT RESOLVED, that the issuance of a
series of Preferred Stock of the Corporation is hereby authorized, and the designation, amount, powers, preferences and relative, participating, optional and other special rights and qualifications, limitations and restrictions thereof, of the
shares of such series of Preferred Stock of the Corporation, are hereby fixed as follows: 
 
1.    Designation; Class and Amount; Certain Definitions.    The Preferred Stock, the issuance of which is hereby authorized, shall comprise 21,815,386
shares the distinctive serial designation of which shall be “$0.925 Series D Non-Cumulative Convertible Preferred Stock” which is sometimes herein referred to as “Series D Preferred Stock.” The number of shares of Series D
Preferred Stock which are purchased or otherwise acquired by the Corporation or converted into Common Stock shall be canceled and shall revert to authorized but unissued shares of Series D Preferred Stock. Certain capitalized terms used herein have
the meanings specified therefor in Section 11 below. 
 
2.    Dividends; Priority. 
 
(a)  Payments of Dividend; Series D Preferred Stock.    Each Holder of shares of Series D Preferred Stock shall be entitled to receive, when and if declared by the Board, in respect of
each share of Series D Preferred Stock, out of the funds of the Corporation legally available therefor, for each Dividend Period or portion thereof, quarterly cash dividends in an amount per share equal to $0.23125 from and after the date of
issuance of the shares of Series D Preferred Stock (the “Issue Date”), as long as the shares of Series D Preferred Stock remain outstanding. No interest, or sum of money in lieu of interest, shall be payable in respect of any
dividend payment or payments on shares of Series D Preferred Stock, which are not paid. 
 
(b)  Payment and Record Dates.    Dividends accrued on the Series D Preferred Stock in respect of each Dividend Period shall be payable, when and if declared by the
Board in arrears concurrently with each date of payment (each such date, a “Dividend Payment Date”) by the Corporation of quarterly cash dividends on the Common Stock in respect of such Dividend 







Period; provided, however, that if any such day is not a Business Day the applicable
Dividend Payment Date shall be the next succeeding day that is a Business Day; and provided, further that if no quarterly cash dividends are paid on the Common Stock in respect of any such Dividend Period, the Dividend Payment Date
shall mean such date as may be determined by the Board within three months following the end of such Dividend Period; provided, however, dividends payable with respect to the Dividend Period immediately following the Issue Date shall
accrue from the Issue Date. Dividends on the Series D Preferred Stock shall accrue on a daily basis from the commencement of each Dividend Period. Dividends will cease to accrue in respect of any shares of Series D Preferred Stock on the Surrender
Date in respect of a conversion pursuant to Section 8(a) or on the Redemption Date in respect of a redemption. Dividends payable on the Series D Preferred Stock for any Dividend Period constituting less than a full fiscal quarter shall be computed
ratably on the basis of a 360-day year of twelve (12) 30-day months. Dividends for any Dividend Period shall not be cumulative to the extent not paid in full on each Dividend Payment Date. Dividends on the Series D Preferred Stock in respect of any
Dividend Period unpaid as of the Dividend Payment Date for such Dividend Period shall permanently remain unpaid. The foregoing notwithstanding, dividends on account of arrears for any past Dividend Periods may be declared and paid at any time,
without reference to any regular Dividend Payment Date. Dividends shall be payable to the Holders as they appear on the Stock Books not exceeding forty (40) days preceding the relevant Dividend Payment Date. Dividends shall be paid in cash, by wire
transfer in immediately available funds to the accounts designated by the respective Holders in written notices given to the Corporation at least five (5) Business Days prior to the payment date or by such other means as may be agreed to by the
Corporation and the respective Holders, such wire transfer to be effected for good value on or before the Dividend Payment Date. 
 
(c)  Special Dividends; Notice.    Notwithstanding anything in this Certificate of Designations to
the contrary, the holders of the Series D Preferred Stock shall participate in all Special Dividends on a share-for-share basis with the holders of Common Stock, as if shares of the Series D Preferred Stock were converted into Common Stock
immediately prior to the record date with respect to each such Special Dividend. 
 
(d)  Priority as to Dividends; Restriction on Dividends, Redemption, etc.    The Corporation shall not, for so long as the Series D Preferred Stock shall remain
outstanding, directly or indirectly, declare or pay or set apart for payment any dividends (including cumulative dividends) or make (or permit any Subsidiary to make) any other distributions on, or payment on account of the purchase, redemption or
other retirement or acquisition for value of the Common Stock, any other capital stock of the Corporation ranking equal to or junior to the Series D Preferred Stock as to dividends or as to distribution of assets upon any liquidation, dissolution or
winding-up of the affairs of the Corporation or any options, warrants or rights to purchase or acquire Common Stock or any such capital stock or any securities convertible into or exchangeable for shares of Common Stock or any such capital stock,
except that such payment of dividends and such other distributions and payments may be made so long as full dividends payable on the Series D Preferred Stock for the Dividend Period commencing immediately prior to the date of such dividend,
distribution or other payment have been or are concurrently paid (or a sum sufficient for the payment thereof set apart for such payment subject to declaration thereof); provided, however, that the foregoing restrictions shall not
apply to: (i) any dividend payable solely in shares of any stock of the Corporation ranking, as to dividends and as to 
 

2 








distribution of assets upon any liquidation, dissolution or winding-up of the affairs of the Corporation,
junior to the Series D Preferred Stock (or payable solely in options, warrants or rights to purchase or acquire any such stock) or (ii) any distribution pursuant to any employee or director incentive or benefit plan or arrangement (including any
employment, severance or consulting agreement) of the Corporation or any Subsidiary heretofore or hereafter adopted or (iii) any distribution pursuant to a redemption, at the stated redemption price, of any rights granted to Holders of Common Stock
pursuant to a stockholder rights plan or (iv) any dividend approved in writing by the holders of at least 66 2/3 percent of all shares of Series D Preferred Stock then outstanding. Holders of shares of Series D Preferred Stock shall be entitled to
receive dividends in accordance with the foregoing clause (a) of this Section 2 in preference to and in priority over any dividend upon any securities junior to the Series D Preferred Stock. 
 
3.    Voting
Rights.    (a)  Holders of shares of Series D Preferred Stock, voting together as a single class with holders of shares of Common Stock (and with holders of any other class or series of stock which may similarly be
entitled to vote with the holders of Common Stock) shall be entitled at any meeting of stockholders called for the purpose of voting on (or acting by written consent without need of any advance notice) (i) any proposed amendment to the Certificate
of Incorporation or By-laws which would reasonably have the effect of modifying in any way Section 1, Article Twelfth of the Amended Certificate of Incorporation of the Corporation dated January 15, 1998, electing that Sections 1145 through 1155 of
Title 18 of the Oklahoma General Corporation Law (the “Control Share Acquisition Statute“) shall not apply to the Corporation, or would reasonably cause the Corporation to become subject to (a) the Control Share Acquisition Statute
or (b) any other provisions which are substantially similar to the Control Share Acquisition Statute, to abstain or vote for or against such amendment and (ii) any transaction or series of transactions submitted to a vote of the stockholders of the
Corporation which, if consummated, would constitute a Change in Control, to vote with respect to such transaction(s). When voting together with the holders of shares of Common Stock on any such transaction(s), each share of Series D Preferred Stock
shall carry, as of the record date applicable to such vote, a number of votes equal to the number of votes carried in the aggregate by the number of shares of Common Stock issuable upon conversion of one share of Series D Preferred Stock into Common
Stock in accordance with Section 8 below. 
 
(a)  Except as provided by this Section 3 and Sections 4 and 9 below, or as otherwise may be required by applicable law, the Holders of Series D Preferred Stock shall not be entitled, by virtue of their being Holders
thereof, to vote in any election of directors to the Board of the Corporation, or with respect to any other matter submitted to the stockholders of the Corporation. Where a vote of the Holders, voting as a separate class, may be required by
applicable law or by this Section 3 or Section 4 or 9, each share of Series D Preferred Stock shall carry one vote. 
 
4.    Covenants.    So long as any shares of Series D Preferred Stock are outstanding, the
Corporation covenants and agrees with and for the benefit of the Holders of such shares that without the affirmative vote or consent of Holders of 66 2/3 percent of all shares of the Series D Preferred Stock then outstanding, voting as a separate
class in person or by proxy or by written consent delivered to the Secretary of the Corporation, the Corporation shall not amend, alter or repeal any provision of the Certificate of Incorporation of the Corporation, this Certificate of Designations,
or any amendment or supplement to any of the foregoing, so as to affect adversely 
 

3 








the rights, powers, preferences, qualifications, limitations or restrictions of any Holder of Series D
Preferred Stock. 
 
5.    Optional Redemption.    Subject to the rights of Holders of shares of Series D Preferred Stock set forth in Section 8 hereof, the Corporation may, at its option, redeem, in the
manner provided for in Section 6 hereof, on or after August 1, 2006, all or a portion of the shares of Series D Preferred Stock at the Redemption Price per share if the Closing Price of the Common Stock exceeds $25.00 for 30 consecutive Trading Days
prior to the date notice is given by Corporation pursuant to Section 6 hereof of its intention to redeem all or a portion of the shares of Series D Preferred Stock pursuant to this Section 5. The “Redemption Price” shall equal the
product of (x) $20.00 and (y) the number of shares of Common Stock then issuable upon the conversion of one share of Series D Preferred Stock. 
 
6.    Procedure for Redemption.    (a)  In the event that the Corporation shall
redeem shares of Series D Preferred Stock pursuant to Section 5 hereof, notice of such redemption (a “Redemption Notice”) shall be mailed by first-class mail, postage prepaid, not less than 30 days nor more than 90 days, except as
provided below, prior to the redemption date (the “Redemption Date”) described in such notice, to the Holders of record of shares to be redeemed at their respective addresses as they shall appear in the records of the Corporation;
provided, however, that failure to give such notice or any defect therein or the mailing thereof shall not affect the validity of the proceeding for the redemption of any shares so to be redeemed except as to the Holder to whom the
Corporation has failed to give such notice or except as to the Holder to whom notice was defective. Each such notice shall state: (i) the Redemption Date; (ii) the number of shares of Series D Preferred Stock to be redeemed; (iii) the Redemption
Price; (iv) the place or places where certificate for such shares are to be surrendered for payment of the redemption price; (v) that dividends on the shares to be redeemed ceased to accrue as of the date of such notice; and (vi) that the
Holder’s right to convert such shares into shares of Common Stock shall terminate on the close of business on the second Business Day preceding such Redemption Date. In the event that the Corporation has delivered a Redemption Notice to the
Shareholder and the Shareholder is then precluded under Section 4.2(a), (b) or (c) of the Registration Rights Agreement from effecting an underwritten offering of Common Stock or Series D Preferred Stock, then the Redemption Date shall automatically
be extended until the ninety-first (91st) day following the date that the restrictions set forth in Section 4.2(a),
(b) or (c) of the Registration Rights Agreement have expired. 
 
(a)  In the event that fewer than all shares of Series D Preferred Stock represented by a surrendered certificate are to be redeemed hereunder, a new certificate shall be issued at the Corporation’s expense
representing the shares of Series D Preferred Stock not so redeemed. 
 
(b)  Effective on the Redemption Date, any shares of Series D Preferred Stock redeemed shall no longer be deemed outstanding, all rights of the Holders thereof as preferred stockholders of the Corporation shall
cease and thereupon the certificate(s) theretofore representing shares of Series D Preferred Stock shall represent only the right to receive the Redemption Price in respect thereof. 
 

4 








 
(d)  On or prior to the Redemption Date, the Redemption Price with respect to all the shares of Series D Preferred Stock to be redeemed shall be deposited with the Corporation’s transfer agent. 
 
7.    Liquidation
Preference.    In the event of any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Corporation, the Holders of shares of Series D Preferred Stock then outstanding shall be entitled to be
paid out of the assets of the Corporation available for distribution to its stockholders an amount per share in cash equal to the amount that would be payable on one share of Common Stock (such amount payable being adjusted appropriately to reflect
any stock split, stock dividend, reverse stock split, or any transaction with comparable effect upon the Common Stock and assuming conversion of all shares of Series D Preferred Stock then outstanding into shares of Common Stock immediately prior to
such liquidation, dissolution or winding-up), plus all dividends then due on the Series D Preferred Stock (the “Liquidation Preference”). This entitlement of the Holders of shares of Series D Preferred Stock shall be satisfied
before any similar payment shall be made or any assets distributed to the holders of the Common Stock or any other security junior in rank to the Series D Preferred Stock as to distribution of assets upon such dissolution, liquidation or winding-up.
If the assets of the Corporation are not sufficient to pay in full the liquidation payments payable to all of the Holders of the outstanding shares of Series D Preferred Stock, then the Holders of all such shares shall share ratably in such
distribution of assets in accordance with the respective liquidation preferences to which they are entitled. For the purposes of this section, neither the voluntary sale, conveyance, exchange or transfer (for cash, shares of stock, securities or
other consideration) of all or substantially all of the property or assets of the Corporation nor the consolidation or merger of the Corporation with one or more other corporations shall be deemed to be a liquidation, dissolution or winding-up,
voluntary or involuntary, unless such voluntary sale, conveyance, exchange or transfer shall be in connection with a dissolution or winding up of the business of the Corporation. 
 
8.    Conversion. 
 
(a)  Conversion Right.    The Holder of any share or shares of Series D
Preferred Stock shall have the right, at any time, at such Holder’s option, to convert, without the payment of additional consideration, each share of Series D Preferred Stock held by that Holder into one fully paid and nonassessable share of
Common Stock (as adjusted pursuant to Section 8(c) hereof); provided, however, that shares of the Series D Preferred Stock Beneficially Owned by any member of the Shareholder Group shall not be convertible unless the aggregate of the
regular cash dividends for the fiscal year immediately prior to such conversion that would have been payable with respect to all the shares of Common Stock issuable upon the conversion of one share of Series D Preferred Stock is greater than $0.925
(the “Conversion Threshold”); provided, further, that the shares of Series D Preferred Stock Beneficially Owned by any member of the Shareholder Group shall not be convertible if such conversion would have a material
adverse effect on the exemptions from the Public Utility Holding Company Act of 1935, as amended, of the Corporation or any of its Subsidiaries or Parent, the Shareholder or any affiliate of the Shareholder. Special or extraordinary dividends shall
not be taken into account in determining whether the Conversion Threshold has been met. Notwithstanding anything in this Section 8(a) to the contrary, any member of the Shareholder Group may convert shares of Series D Preferred Stock into shares of
Common Stock at any time in connection with, and 
 

5 








immediately prior to, a Transfer pursuant to subsections (a)-(c) and (e) of Section 4.3 of the Shareholder
Agreement. 
 
(b)  Conversion
Procedures.    (i)  Any Holder of shares of Series D Preferred Stock desiring to convert such shares into Common Stock shall surrender the certificate(s) evidencing such shares of Series D Preferred Stock of the
Holder at the office of the Corporation’s transfer agent. Such surrendered certificate(s), if the Corporation shall so require, shall be duly endorsed to the Corporation or in blank, or accompanied by proper instruments of transfer to the
Corporation or in blank, and shall be accompanied by written notice to the Corporation that the Holder elects so to convert such shares of Series D Preferred Stock, which notice shall specify the name or names (with address or addresses) in which
the Holder wishes the certificate(s) evidencing shares of Common Stock to be issued, in exchange for that certificate or those certificates so surrendered. 
 
(ii)  The Corporation shall, within five (5) Business Days after such surrender of certificates evidencing
shares of Series D Preferred Stock accompanied by written notice and in compliance with any other conditions contained herein, issue and deliver, or cause to be issued and delivered, to the person(s) for whose account such certificate(s) evidencing
shares of Series D Preferred Stock were so surrendered, or to the nominee(s) of such Person(s), certificates representing the number of full shares of Common Stock to which such Person shall be entitled pursuant to the then-applicable conversion
rate. Such conversion shall be deemed to have been made on the date of such surrender of the certificate(s) evidencing shares of Series D Preferred Stock to be converted (the “Surrender Date”) and the Person(s) entitled to receive
the Common Stock deliverable upon conversion of such Series D Preferred Stock shall be treated for all purposes as the record holder(s) of such Common Stock on such date and thereafter. Conversion of Series D Preferred Stock may otherwise be
achieved in accordance with such procedures as the Corporation and a majority of the Holders may agree. 
 
(iii)  In the event that fewer than all shares of Series D Preferred Stock represented by a surrendered
certificate are to be converted hereunder, a new certificate shall be issued at the Corporation’s expense representing the shares of Series D Preferred Stock not so converted. 
 
(iv)  Effective on the day following the Surrender Date, dividends shall cease to
accrue on any shares of Series D Preferred Stock surrendered for conversion, such shares of Series D Preferred Stock shall no longer be deemed outstanding, all rights of the Holders thereof as preferred stockholders of the Corporation shall cease
(other than the right to receive dividends declared or otherwise payable to Holders of Series D Preferred Stock on a record date prior to the Surrender Date) and thereupon the certificate(s) theretofore representing shares of Series D Preferred
Stock shall represent only the right to receive the Common Stock deliverable upon conversion in respect thereof. 
 
(v)  If any shares of Series D Preferred Stock are surrendered for conversion subsequent to the record date
preceding a Dividend Payment Date but on or prior to such Dividend Payment Date (except shares called for redemption on a redemption date between such record date and such Dividend Payment Date), the Holder of such shares at 
 

6 








the close of business on such record date shall be entitled to receive the dividend
payable on such shares on such Dividend Payment Date notwithstanding the conversion thereof. 
 
(c)  The conversion rate shall be adjusted from time to time as follows: 
 
(i)  In case the Corporation shall, at any time or from time to time while any of the shares of Series D
Preferred Stock are outstanding, (A) pay a dividend in shares of its Common Stock, (B) subdivide its outstanding shares of Common Stock into a larger number of shares, or (C) combine its outstanding shares of Common Stock into a smaller number of
shares, the conversion rate in effect immediately prior to such action shall be adjusted so that the Holder of any shares of Series D Preferred Stock thereafter surrendered for conversion shall be entitled to receive the number of shares of Common
Stock which such Holder would have owned or have been entitled to receive immediately following such action had such shares of Series D Preferred Stock been converted immediately prior thereto. An adjustment made pursuant to this Section 8(c)(i)
shall become effective retroactively to immediately after the opening of business on the Business Day following the record date in the case of a dividend and shall become effective immediately after the opening of business on the Business Day
following the effective date in the case of a subdivision or combination. If, as a result of an adjustment made pursuant to this Section 8(c)(i), the Holder of any shares of Series D Preferred Stock thereafter surrendered for conversion shall become
entitled to receive shares of two or more classes of capital stock of the Corporation, the Board of Directors (whose determination shall be conclusive) shall determine the allocation of the adjusted conversion rate between or among shares of such
classes of capital stock. 
 
(ii)  In case the Corporation shall, at any time or from time to time while any of the shares of Series D Preferred Stock are outstanding, issue rights or warrants to all holders of shares of its Common Stock entitling them
to subscribe for or purchase shares of Common Stock (or securities convertible into or exchangeable for Common Stock) at a price per share less than the current Market Price per share of Common Stock, at such record date, the conversion rate shall
be adjusted so that it shall equal the rate determined by multiplying the conversion rate in effect immediately prior to the date of issuance of such rights or warrants by a fraction, the numerator of which shall be the number of shares of Common
Stock outstanding on the date of issuance of such rights or warrants plus the number of additional shares of Common Stock offered for subscription or purchase, and the denominator of which shall be the number of shares of Common Stock outstanding on
the date of issuance of such rights or warrants plus the number of shares which the aggregate offering price of the total number of shares so offered would purchase at such current market price. For the purposes of this Section 8(c)(ii), the
issuance of rights or warrants to subscribe for or purchase securities convertible into Common Stock shall be deemed to be the issuance of rights or warrants to purchase the shares of Common Stock into which such securities are convertible at an
aggregate offering price equal to the aggregate offering price of such securities plus the minimum aggregate amount (if any) payable upon conversion of such securities into shares of Common Stock; provided, however, that if all of the
shares of Common Stock subject to such rights or warrants have not been issued when such rights or warrants expire, then the conversion rate shall promptly be readjusted to the conversion rate which would then be 
 

7 








in effect had the adjustment upon the issuance of such rights or warrants been made on the
basis of the actual number of shares of Common Stock issued upon the exercise of such rights or warrants. The foregoing provision shall not apply to issuances of rights pursuant to a stockholder rights plan provided that such rights are issued
together with the Common Stock upon conversion of the Series D Preferred Stock. An adjustment made pursuant to this Section 8(c)(ii) shall become effective retroactively immediately after the record date for the determination of stockholders
entitled to receive such rights or warrants. 
 
(iii)  In case the Corporation shall, at any time or from time to time while any of the shares of Series D Preferred Stock are outstanding, distribute to all holders of shares of its Common Stock evidences of its
indebtedness or securities or assets (excluding cash dividends payable out of consolidated earnings or retained earnings or dividends payable in shares of Common Stock) or rights or warrants to subscribe for securities of the Corporation or any of
its subsidiaries (excluding those referred to in Section 8(c)(ii)), then in each such case the conversion rate shall be adjusted so that it shall equal the rate determined by multiplying the conversion rate in effect immediately prior to the date of
such distribution by a fraction, the numerator of which shall be the current Market Price per share of the Common Stock on the record date referred to below, and the denominator of which shall be such current market price per share of the Common
Stock less the then fair market value of the portion of the assets or evidences of indebtedness or securities or assets so distributed or of such subscription rights or warrants applicable to one share of Common Stock. Such adjustment shall become
effective retroactively immediately after the record date for the determination of stockholders entitled to receive such distribution. 
 
(iv)  The Corporation shall be entitled at its option to make such additional adjustments in the conversion
rate, in addition to those required by subsections 8(c)(i), 8(c)(ii) and 8(c)(iii), as shall be necessary in order that any dividend or distribution in shares of stock, subdivision or combination of shares of Common Stock, issuance of rights or
warrants, evidences of indebtedness or assets (other than cash dividends payable out of consolidated earnings or retained earnings) referred to above, shall not be taxable to the Holders of shares of Series D Preferred Stock. 
 
(v)  In any case in which this
Section 8(c) shall require that an adjustment be made retroactively immediately following a record date, the Corporation may elect to defer (but only for five (5) Business Days following the filing of the statement referred to in Section 8(c)(vii))
issuing to the holder of any shares of this Series converted after such record date (A) the shares of Common Stock and other capital stock of the Corporation issuable upon such conversion over and above (B) the shares of Common Stock and other
capital stock of the Corporation issuable upon such conversion on the basis of the conversion rate prior to adjustment. 
 
(vi)  Notwithstanding any other provisions of this Section 8(c), the Corporation shall not be required to make
any adjustment of the conversion rate (A) in respect of any Special Dividend in which the holders of Series D Preferred Stock participate as provided in Section 2(c) or (B) unless such adjustment would require an increase or decrease of at

 

8 








least 1% in such rate (any lesser adjustment shall be carried forward and shall be made at
the time of and together with the next subsequent adjustment which, together with any adjustment or adjustments so carried forward, shall amount to an increase or decrease of at least 1% in such rate). 
 
(vii)  Whenever an adjustment in the
conversion rate is required, the Corporation shall forthwith place on file with its Transfer Agent a statement signed by its Chief Executive Officer, Chief Financial Officer or a Vice President and by its Secretary, Assistant Secretary, Treasurer or
Assistant Treasurer, stating the adjusted conversion rate determined as provided herein. Such statements shall set forth in reasonable detail such facts as shall be necessary to show the reason and the manner of computing such adjustment. Promptly
after the adjustment of the conversion rate, the Corporation shall mail a notice thereof to each holder of shares of Series D Preferred Stock. 
 
(d)  Reservation of Shares; etc.    (i)  The Corporation shall at all times reserve and
keep available, free from preemptive rights, out of its authorized and unissued stock, such number of shares of its Common Stock as shall from time to time be sufficient to effect the conversion of all shares of the Series D Preferred Stock from
time to time outstanding, solely for the purpose of effecting such conversion. The Corporation shall, from time to time, in accordance with the laws of the State of Oklahoma, increase the authorized number of shares of Common Stock if at any time
the number of shares of authorized and unissued Common Stock shall not be sufficient to permit the conversion of all the then-outstanding shares of Series D Preferred Stock. 
 
(ii)  If any shares of Common Stock required to be reserved hereunder for purposes
of conversion require registration with or approval of any governmental authority under any Federal or state law before such shares may be issued upon conversion, the Corporation shall, in good faith and as expeditiously as possible, cause such
shares to be duly registered or approved as the case may be. If the Common Stock is listed on the New York Stock Exchange or any other national or foreign securities exchange, the Corporation shall, if permitted by the rules of such exchange, list
and keep listed on such exchange, upon official notice of issuance, all shares of Common Stock issuable upon conversion of Series D Preferred Stock. 
 
(iii)  The Corporation will pay any and all taxes that may be payable in respect of the issuance or delivery of
shares of Common Stock upon conversion of shares of Series D Preferred Stock pursuant hereto. The Corporation shall not, however, be required to pay any tax which may be payable in respect of any transfer involved in the issuance and delivery of
shares of Common Stock in a name other than that in which the shares of Series D Preferred Stock so converted were registered and no such issuance or delivery shall be made unless and until the person requesting such issuance has paid to the
Corporation the amount of any such tax or has established to the satisfaction of the Corporation that such tax has been paid. 
 
(e)  Reclassifications, Consolidations, Mergers or Sales of Assets.    In case of (i) any
reclassification or change of outstanding shares of Common Stock (other than a change in par value or from par value to no par value or from no par value to par value, or as a result of a subdivision or combination), (ii) any consolidation or merger
of the Corporation with one or 
 

9 








more other corporations (other than a consolidation or merger in which the Corporation is the continuing
corporation and which does not result in any reclassification or change of outstanding shares of Common Stock issuable upon conversion of Series D Preferred Stock), (iii) any sale or conveyance to another corporation or other entity of all or
substantially all of the property of the Corporation, or (iv) any other transaction which would constitute a Change in Control of the Corporation, then the Corporation, or such successor corporation or other entity, as the case may be, shall make
appropriate provision so that the holder of each share of Series D Preferred Stock then outstanding shall have the right to convert such share into the kind and amount of shares of stock or other securities and property receivable upon such
consolidation, merger, sale, reclassification, change or conveyance by a holder of the number of shares of Common Stock into which such shares of Series D Preferred Stock might have been converted immediately prior to such consolidation, merger,
sale, reclassification, change or conveyance, subject to adjustment which shall be as nearly equivalent as may be practicable to the adjustments provided for in Section 8(c). The provisions of this paragraph shall apply similarly to successive
consolidations, mergers, sales or conveyances. 
 
9.    Priority.    The Series D Preferred Stock shall be senior in rank, both as to dividends and as to distribution of assets upon any liquidation, dissolution or winding-up of the
affairs of the Corporation, to the Common Stock, or any class of equity securities of the Corporation which by its terms are junior to the Series D Preferred Stock, and shall not be junior in rank with respect to any class or series of Preferred
Stock that may be issued by the Corporation, unless the Holders of 66 2/3 percent of the outstanding shares of the Series D Preferred Stock shall consent to the creation, reclassification or authorization of any class or series of the
Corporation’s capital stock ranking prior to the Series D Preferred Stock as to dividends or as to distributions of assets upon liquidation, dissolution or winding-up of the Corporation, whether voluntary or involuntary, or any security
convertible into shares of such class or series. 
 
10.    Notices.    The Corporation shall provide notice to each Holder of any action taken or proposed to be taken or any determination made by the Corporation and/or the Shareholder
under the terms of this Certificate of Designations. Notice of any such action or determination by the Corporation and/or the Shareholder and all other notices and other communications provided for in this Certificate of Designations shall be

“Affiliate” shall mean, with
respect to any Person, any other Person that directly or indirectly through one or more intermediaries controls or is controlled by or is under common control with such Person. For the purposes of this definition, “control,” when used with
respect to any particular Person, means the power to direct the management and policies of such Person, directly or indirectly, whether through the ownership of voting securities, by contract or otherwise; and the terms “controlling” and
“controlled” have meanings correlative to the foregoing. 
 
“Beneficial Owner” (and, with correlative meanings, “Beneficially Own” and “Beneficial Ownership”) of any interest means a Person who, together with his, her or its Affiliates, is or may
be deemed a beneficial owner of such interest for purposes of Rule 13d-3 or 13d-5 under the Securities Exchange Act of 1934, as amended, or who, together with his, her, or its Affiliates, has the right to become such a beneficial owner of such
interest (whether such right is exercisable immediately or only after the passage of time) pursuant to any agreement, arrangement or understanding, or upon the exercise, conversion or exchange of any warrant, right or other instrument, or otherwise.
