Exhibit 4.1 FORM OF CERTIFICATE OF DESIGNATIONS of $3.25 CONVERTIBLE PREFERRED STOCK of DELTA HOLDCO CORP. (Pursuant to Section 151 of the Delaware General Corporation Law) Delta Holdco Corp., 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 acting by written consent on January 30, 2002: RESOLVED, that pursuant to the authority granted to and vested in the Board of Directors of this Corporation in accordance with the provisions of the Certificate of Incorporation of the Corporation, a series of Convertible Preferred Stock, par value $5.00 per share, of the Corporation, be and hereby is created, and that the number of shares thereof and the voting powers, designations, preferences, limitations, restrictions, relative rights and distinguishing designation of the shares of such series are as follows: Section 1. Designation and Amount. The designation of such series of Preferred Stock authorized by this resolution shall be the $3.25 Convertible Preferred Stock (herein the "Convertible Preferred Stock"). The number of shares of Convertible Preferred Stock shall be 2,300,000. Section 2. Rank. All shares of Convertible Preferred Stock shall rank prior, both as to payment of dividends and as to distributions of assets upon liquidation, dissolution or winding up of the Corporation, whether voluntary or involuntary, to all of the Corporation's now or hereafter issued Common Stock. The term "Common Stock" shall mean the Common Stock, $1.60 par value per share, of the Corporation as the same exists at the date hereof or as such stock may be constituted from time to time. Section 3. Dividends. The holders of Convertible Preferred Stock shall be entitled to receive, when, as and if declared by the Board of Directors out of funds at the time legally available therefor, dividends at the rate of $3.25 per annum per share, and no more, which shall be fully cumulative, shall accrue without interest from the date of first issuance and shall be payable in cash quarterly in arrears on February 15, May 15, August 15 and November 15 of each year (except that if any such date is a Saturday, Sunday or legal holiday, then such dividend shall be payable on the next succeeding day that is not a Saturday, Sunday or legal holiday) to holders of record as they appear on the stock transfer books of the Corporation on such record dates, not more than 60 nor less than 10 days preceding the payment dates for such dividends, as are fixed by the Board of Directors. For purposes hereof, the term "legal holiday" shall mean any day on which banking institutions are authorized to close in New York, New York or in Houston, Texas. Subject to the next paragraph of this Section 3, dividends on account of arrears for any past dividend period may be declared and paid at any time, without reference to any regular dividend payment date. The amount of dividends payable per share of Convertible Preferred Stock for each quarterly dividend period shall be computed by dividing the annual amount by four. The amount of dividends payable for the initial dividend period and any period shorter than a full quarterly dividend period shall be computed on the basis of a 360-day year of twelve 30-day months. Holders of Convertible Preferred Stock shall not be entitled to any dividend, whether payable in cash, property or stock, in excess of the full cumulative dividends on such shares of Cumulative Preferred Stock. On each dividend payment date all dividends which shall have accrued on each share of Convertible Preferred Stock outstanding on such dividend payment date shall accumulate and be deemed to become "due" whether or not there shall be funds legally available for the payment thereof. Any dividend which shall not be paid on the dividend payment date on which it shall become due shall be deemed to be "past due" until such dividend shall be paid or until the share of Convertible Preferred Stock with respect to which such dividend became due shall no longer be outstanding, whichever is the earlier to occur. No interest, sum of money in lieu of interest, or other property or securities shall be payable in respect of any dividend payment or payments which are past due. Dividends paid on shares of Convertible Preferred Stock in an amount less than the total amount of such dividends at the time accumulated and payable on such shares shall be allocated pro rata on a share-by-share basis among all such shares at the time outstanding. No dividends or other distributions, other than dividends payable solely in shares of Common Stock or other capital stock of the Corporation ranking junior as to dividends and as to liquidation rights to the Convertible Preferred Stock which is neither convertible into, nor exchangeable or exercisable for, any securities of the Corporation other than Common Stock or other capital stock of the Corporation ranking junior as to dividends and as to liquidation rights to the Convertible Preferred Stock, shall be paid, or declared and set apart for payment, and no purchase, redemption or other acquisition shall be made by the Corporation of, any shares of Common Stock or other capital stock of the Corporation ranking junior as to dividends or as to liquidation rights to the Convertible Preferred Stock (the "Junior Dividend Stock") unless and until all accrued and unpaid dividends on the Convertible Preferred Stock, including the full dividend for the then current dividend period, shall have been paid or declared and set apart for payment and the Corporation is not in default in respect of the optional redemption of any shares of Convertible Preferred Stock. No full dividends shall be paid or declared and set apart for payment on any class or series of the Corporation's capital stock ranking, as to dividends, on a parity with the Convertible Preferred Stock (the "Parity Dividend Stock") for any period unless full cumulative dividends have been, or contemporaneously are, paid or declared and set apart for such payment on the Convertible Preferred Stock for all dividend payment periods terminating on or prior to the date of payment of such full cumulative dividends. No full dividends shall be paid or declared and set apart for payment on the Convertible Preferred Stock for any period unless full -2- cumulative dividends have been, or contemporaneously are, paid or declared and set apart for payment on the Parity Dividend Stock for all dividend periods terminating on or prior to the date of payment of such full cumulative dividends. When dividends are not paid in full upon the Convertible Preferred Stock and the Parity Dividend Stock, all dividends paid or declared and set aside for payment upon shares of Convertible Preferred Stock and the Parity Dividend Stock shall be paid or declared and set aside for payment pro rata so that the amount of dividends paid or declared and set aside for payment per share on the Convertible Preferred Stock and the Parity Dividend Stock shall in all cases bear to each other the same ratio that accrued and unpaid dividends per share on the shares of Convertible Preferred Stock and the Parity Dividend Stock bear to each other. 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 this Section 3, purchase or otherwise acquire such shares at such time and in such manner. Any reference to "distribution" contained in this Section 3 shall not be deemed to include any distribution made in connection with any liquidation, dissolution or winding up of the Corporation, whether voluntary or involuntary. Section 4. Liquidation Preference. In the event of any liquidation, dissolution or winding up of the Corporation, whether voluntary or involuntary, the holders of Convertible Preferred Stock shall be entitled to receive out of the assets of the Corporation, whether such assets are stated capital or surplus of any nature, an amount equal to the dividends accrued and unpaid thereon to the date of final distribution to such holders, whether or not declared, without interest, and a sum equal to $50.00 per share, and no more, before any payment shall be made or any assets distributed to the holders of Common Stock or any other class or series of the Corporation's capital stock ranking junior as to liquidation rights to the Convertible Preferred Stock (the "Junior Liquidation Stock"). In the event the assets of the Corporation available for distribution to stockholders upon any liquidation, dissolution or winding up of the Corporation, whether voluntary or involuntary, shall be insufficient to pay in full the amounts payable with respect to the Convertible Preferred Stock and any other class or series of the Corporation's capital stock which may hereafter be created having parity as to liquidation rights with the Convertible Preferred Stock (the "Parity Liquidation Stock"), the holders of the Convertible Preferred Stock and the holders of the Parity Liquidation Stock shall share ratably in any distribution of assets of the Corporation in proportion to the full respective preferential amounts to which they are entitled (but only to the extent of such preferential amounts). After payment in full of the liquidation preferences of the shares of Convertible Preferred Stock, the holders of such shares shall not be entitled to any further participation in any distribution of assets by the Corporation. Neither a consolidation, merger or other business combination of the Corporation with or into another corporation or other entity nor a sale or transfer of all or part of the Corporation's assets for cash, securities or other property shall be considered a liquidation, dissolution or winding up of the Corporation for purposes of this Section 4 (unless in connection therewith the liquidation of the Corporation is specifically approved). The holder of any shares of Convertible Preferred Stock shall not be entitled to receive any payment owed for such shares under this Section 4 until such holder shall cause to be -3- delivered to the Corporation (i) the certificate(s) representing such shares of Convertible Preferred Stock and (ii) transfer instrument(s) satisfactory to the Corporation and sufficient to transfer such shares of Convertible Preferred Stock to the Corporation free of any adverse interest. As in the case of the Redemption Price referred to below, no interest shall accrue on any payment upon liquidation after the due date thereof. Section 5. Redemption at Option of the Corporation. The Corporation, at its option, may at any time redeem for shares of Common Stock the Convertible Preferred Stock, in whole or from time to time in part, on any date set by the Board of Directors, at the following redemption prices if redeemed during the twelve-month period beginning May 15 of the year specified below: Year Price Per Share ---- --------------- 2001 $50.650 2002 $50.325 and thereafter at $50.00 per share, plus, in each case, an amount equal to all dividends on the Convertible Preferred Stock accrued and unpaid thereon, whether or not declared or due, to the date fixed for redemption, such sum being hereinafter referred to as the "Redemption Price" (subject to the right of the holder of record of shares of Convertible Preferred Stock on a record date for the payment of a dividend on the Convertible Preferred Stock to receive the dividend due on such shares of Convertible Preferred Stock on the corresponding dividend payment date). At no time shall the Convertible Preferred Stock be redeemable for cash. The Corporation shall issue in payment of the Redemption Price for each share of Convertible Preferred Stock to be redeemed such number of shares of Common Stock as equals (x) the then-current Redemption Price of the Convertible Preferred Stock, divided by (y) the market price (the "Market Price") of the Common Stock. The Market Price shall be equal to the lower of (i) the average of the daily closing prices of the Common Stock for the 20 consecutive trading days immediately preceding the first business day immediately preceding the date of the applicable redemption notice, or (ii) the closing price of the Common Stock on the trading day immediately preceding the first business day immediately preceding the date of the applicable redemption notice. The "closing price" for each day shall be the last reported sales price regular way or, in case no such reported sales takes place on such day, the average of the closing bid and asked prices regular way for such day, in each case on the New York Stock Exchange Composite Tape or, if not listed on the New York Stock Exchange, on the principal national securities exchange on which the shares of Common Stock are listed or admitted to trading or, if not listed or admitted to trading on a national securities exchange, the last sale price regular way for the Common Stock as published by the National Association of Securities Dealers Automated Quotation System ("NASDAQ"), or if such last sale price is not so published by NASDAQ or if no such sale takes place on such day, the mean between the closing bid and asked prices for the Common Stock as published by NASDAQ. If the shares of Common Stock are not listed or admitted to trading on a national securities exchange or quoted by NASDAQ, the determination of Market Price shall be determined in good faith by the Board of Directors of the Corporation or, if such determination cannot be made, by a nationally recognized independent investment banking firm selected in good faith by the Board of Directors of the Corporation. For the -4- purposes of this Section 5, trading day shall mean a day on which the securities exchange specified for purposes of this Section 5 shall be open for business or, if the shares of Common Stock shall not be listed on such exchange for such period, a day with respect to which quotations of the character referred to in the next preceding sentence shall be reported. In lieu of any fractional share of Common Stock which would otherwise be issued upon any redemption of Convertible Preferred Stock, the Corporation shall pay a cash adjustment in respect of such fractional interest in an amount in cash (computed to the nearest cent) equal to the Market Price multiplied by the fractional interest that otherwise would have been deliverable upon such redemption of such Convertible Preferred Stock. In case of the redemption of less than all of the then outstanding Convertible Preferred Stock, the shares of Convertible Preferred Stock to be redeemed shall be redeemed pro rata or by lot or in such other manner as the Board of Directors may determine. Notwithstanding the foregoing, the Corporation shall not redeem less than all of the Convertible Preferred Stock at any time outstanding until all dividends accrued and in arrears upon all Convertible Preferred Stock then outstanding shall have been paid for all past dividend periods. Not more than 60 nor less than 30 days prior to the redemption date, notice by first class mail, postage prepaid, shall be given to each holder of record of the Convertible Preferred Stock to be redeemed, at such holder's address as it shall appear upon the stock transfer books of the Corporation. Each such notice of redemption shall specify the date fixed for redemption, the Redemption Price, the place or places of payment, that payment will be made upon presentation and surrender of the certificate(s) evidencing the shares of Convertible Preferred Stock to be redeemed, that on and after the redemption date, dividends will cease to accrue on such shares, the then effective conversion price pursuant to Section 6 and that the right of holders to convert shall terminate at the close of business on the redemption date (unless the Corporation defaults in the payment of the Redemption Price). Any notice that is mailed as herein provided shall be conclusively presumed to have been duly given, whether or not the holder of the Convertible Preferred Stock receives such notice; and failure to give such notice by mail, or any defect in such notice, to the holders of any shares designated for redemption shall not affect the validity of the proceedings for the redemption of any other shares of Convertible Preferred Stock. On or after the date fixed for redemption as stated in such notice, each holder of the shares called for redemption shall surrender the certificate evidencing such shares to the Corporation at the place designated in such notice and shall thereupon be entitled to receive payment of the Redemption Price as herein provided. If less than all the shares represented by any such surrendered certificate are redeemed, a new certificate shall be issued representing the unredeemed shares. If, on the date fixed for redemption, shares of Common Stock and funds necessary for the redemption shall be available therefor and shall have been irrecoverably deposited or set aside, then, notwithstanding that the certificates evidencing any shares so called for redemption shall not have been surrendered the dividends with respect to the shares so called shall cease to accrue after the date fixed for redemption, the shares shall no longer be deemed outstanding, the holders thereof shall cease to be holders of Convertible Preferred Stock, and all rights whatsoever with respect to the shares so called for redemption (except the right of the holders to receive payment of the Redemption Price as herein provided without interest upon surrender of their certificates therefor) shall terminate. At the close of business on the redemption date, each holder of -5- Convertible Preferred Stock so redeemed (unless the Corporation defaults on its obligations to delivery shares of Common Stock or cash) shall be, without any further action, deemed a holder of the number of shares of Common Stock for which such Convertible Preferred Stock is redeemable. The shares of Convertible Preferred Stock shall not be subject to the operation of any purchase, retirement, mandatory redemption or sinking fund. The holder of any shares of Convertible Preferred Stock redeemed upon any exercise of the Corporation's redemption right shall not be entitled to receive payment of the Redemption Price for such shares until such holder shall cause to be delivered to the place specified in the notice given with respect to such redemption (i) the certificate(s) representing such shares of Convertible Preferred Stock redeemed and (ii) transfer instrument(s) satisfactory to the Corporation and sufficient to transfer such shares of Convertible Preferred Stock to the Corporation free of any adverse interest. No interest shall accrue on the Redemption Price of any share of Convertible Preferred Stock after its redemption date. All shares of Common Stock which may be delivered upon redemption of the Convertible Preferred Stock will upon delivery be duly and validly issued and fully paid and non-assessable, free of all liens and charges and not subject to any preemptive rights, and prior to giving any notice of redemption the Corporation shall take any corporate action necessary therefor. In the event that any shares of Convertible Preferred Stock shall be converted into Common Stock pursuant to Section 6, then (i) the Corporation shall not have the right to redeem such shares and (ii) shares of Common Stock and any funds which shall have been deposited for the payment of the Redemption Price for such shares of Convertible Preferred Stock shall be returned to the Corporation immediately after such conversion (subject to declared dividends payable to holders of shares of Convertible Preferred Stock on the record date for such dividends being so payable, to the extent set forth in Section 6 hereof, regardless of whether such shares are converted subsequent to such record date and prior to the related dividend payment date). Section 6. Conversion Privilege. (a) Right of Conversion. Subject to and upon compliance with the provisions of this Section 6, each share of Convertible Preferred Stock shall, at the option of the holder thereof, be convertible at any time (unless such share is called for redemption, then to and including but not after the close of business on the date fixed for such redemption, unless the Corporation shall default in payment due upon redemption thereof), into that number of fully paid and non-assessable shares of Common Stock (calculated as to each conversion to the nearest 1/100th of a share) obtained by dividing $50.00 by the Conversion Price (as defined in Section 6(d)) in effect at such time and by surrender of such share so to be converted in the manner provided in Section 6(b). (b) Manner of Exercise of Conversion Privilege. In order to exercise the conversion privilege, the holder of one or more shares of Convertible Preferred Stock to be converted shall surrender such shares at any of the offices or agencies to be maintained for such purpose by the Corporation accompanied by the funds, if any, required by the last paragraph of this Section 6(b) and shall give written notice of conversion in the form provided on such shares -6- of Convertible Preferred Stock (or such other notice as is acceptable to the Corporation) to the Corporation at such office or agency that the holder elects to convert the shares of Convertible Preferred Stock specified in said notice. Such notice shall also state the name or names, together with address or addresses, in which the certificate or certificates for shares of Common Stock which shall be issuable in such conversion shall be issued. Each share of Convertible Preferred Stock surrendered for conversion shall, unless the shares issuable on conversion are to be issued in the same name as the name in which such share is registered, be accompanied by instruments of transfer, in form satisfactory to the Corporation, duly executed by the holder or his duly authorized attorney and an amount sufficient to pay any transfer or similar tax. As promptly as practicable after the surrender of such shares of Convertible Preferred Stock and the receipt of such notice, instruments of transfer and funds, if any, as aforesaid, the Corporation shall issue and shall deliver at such office or agency to such holder, or on his written order, a certificate or certificates for the number of full shares of Common Stock issuable upon the conversion of such share of Convertible Preferred Stock in accordance with the provisions of this Section 6 and a check or cash in respect of any fractional interest in a share of Common Stock arising upon such conversion, as provided in Section 6(c). Each conversion shall be deemed to have been effected immediately prior to the close of business on the date on which such shares of Convertible Preferred Stock shall have been surrendered and such notice (and any applicable instruments of transfer and any required taxes) received by the Corporation as aforesaid, and the person or persons in whose name or names any certificate or certificates for shares of Common Stock shall be issuable upon such conversion shall be deemed to have become the holder or holders of record of the shares represented thereby at such time on such date, and such conversion shall be at the Conversion Price in effect at such time on such date, unless the stock transfer books of the Corporation shall be closed on that date, in which event such person or persons shall be deemed to have become such holder or holders of record at the close of business on the next succeeding day on which such stock transfer books are open, but such conversion shall be at the Conversion Price in effect on the date upon which such shares of Convertible Preferred Stock shall have been surrendered and such notice received by the Corporation. Any shares of Convertible Preferred Stock surrendered for conversion during the period from the close of business on the record date for any dividend payment to the opening of business on the related dividend payment date shall (unless such shares of Convertible Preferred Stock shall have been called for redemption on a date in such period) be accompanied by payment, in funds acceptable to the Corporation, of an amount equal to the dividend otherwise payable on such dividend payment date; provided, however, that no such payment need be made if there shall exist at the time of conversion a default in the payment of dividends on the shares of Convertible Preferred Stocks. An amount equal to such payment shall be paid by the Corporation on such dividend payment date to the holder of such shares of Convertible Preferred Stock at the close of business on such record date; provided, however, that if the Corporation shall default in the payment of dividends on such dividend payment date, such amount shall be paid to the person who made such required payment. Except as provided for above in this Section, no adjustment shall be made for dividends accrued on any shares of Convertible Preferred Stock converted or for dividends on any shares issued upon the conversion of such shares as provided in this Section. -7- (c) Cash Payments in Lieu of Fractional Shares. No fractional shares or scrip representing fractions of shares of Common Stock shall be issued upon conversion of Convertible Preferred Stock. If more than one share of Convertible Preferred Stock shall be surrendered for conversion at one time by the same holder, the number of full shares of Common Stock issuable upon conversion thereof shall be computed on the basis of the aggregate of $50.00 for each such share so surrendered. In lieu of any fractional interest in a share of Common Stock which would otherwise be deliverable upon the conversion of any share of Convertible Preferred Stock, the Corporation shall pay to the holder of such shares an amount in cash (computed to the nearest cent) equal to the closing price (as defined in Section 5 hereof) on the business day next preceding the day of conversion multiplied by the fractional interest that otherwise would have been deliverable upon conversion of such share. (d) Adjustment of Conversion Price. The Conversion Price shall mean and be $100, subject to adjustment from time to time by the Corporation as follows: (i) In case the Corporation shall (A) pay a dividend or make a distribution on its Common Stock in shares of Common Stock, (B) subdivide its outstanding shares of Common Stock into a greater number of shares, (C) combine its outstanding shares of Common Stock into a smaller number of shares, or (D) issue by reclassification of its Common Stock any shares of capital stock of the Corporation, then in each such case the Conversion Price in effect immediately prior to such action shall be adjusted so that the holder of any share of Convertible Preferred Stock thereafter surrendered for conversion shall be entitled to receive the number of shares of Common Stock or other capital stock of the Corporation which he would have owned or been entitled to receive immediately following such action had such share been converted immediately prior to the occurrence of such event. An adjustment made pursuant to this subsection (i) shall become effective immediately after the record date, in the case of a dividend or distribution, or immediately after the effective date, in the case of a subdivision, combination or reclassification. If, as a result of an adjustment made pursuant to this subsection (i), the holder of any share of Convertible Preferred Stock thereafter surrendered for conversion shall become entitled to receive shares of two or more classes of capital stock or shares of Common Stock and other capital stock of the Corporation, the Board of Directors (whose determination shall be conclusive and shall be described in a statement filed by the Corporation with the stock transfer or conversion agent, as appropriate) shall determine the allocation of the adjusted Conversion Price between or among shares of such classes of capital stock or shares of Common Stock and other capital stock. (ii) In case the Corporation shall issue rights or warrants to all holders of its outstanding shares of Common Stock entitling them (for a period expiring within 45 days after the record date mentioned below) to subscribe for or purchase shares of Common Stock at a price per share less than the current market price per share (as determined pursuant to subsection (iv) of this Section 6(d)) of the Common Stock (other than pursuant to any stock option, restricted stock or other incentive or benefit plan or stock ownership or purchase plan for the benefit of employees, directors or officers or any dividend reinvestment plan of the Corporation in effect at the time hereof or any other similar plan adopted or implemented hereafter), then the Conversion Price in effect immediately prior thereto shall be adjusted so that it shall equal the price determined by -8- multiplying the Conversion Price in effect immediately prior to the date of issuance of such rights or warrants by a fraction of which the numerator shall be the number of shares of Common Stock outstanding on the date of issuance of such rights or warrants (immediately prior to such issuance) 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, and of which the denominator shall be the numbers of shares of Common Stock outstanding on the date of issuance of such rights or warrants (immediately prior to such issuance) plus the number of additional shares of Common Stock offered for subscription or purchase. Such adjustment shall be made successively whenever any rights or warrants are issued, and shall become effective immediately after the record date for the determination of stockholders entitled to receive such rights or warrants; provided, however, in the event that all the shares of Common Stock offered for subscription or purchase are not delivered upon the exercise of such rights or warrants, upon the expiration of such rights or warrants the Conversion Price shall be readjusted to the Conversion Price which would have been in effect had the numerator and the denominator of the foregoing fraction and the resulting adjustment been made based upon the number of shares of Common Stock actually delivered upon the exercise of such rights or warrants rather than upon the number of shares of Common Stock offered for subscription or purchase. In determining whether any rights or warrants entitle the holders to subscribe for or purchase shares of Common Stock at less than such current market price, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received by the Corporation for such rights or warrants, the value of such consideration, if other than cash, to be determined by the Board of Directors (whose determination shall be conclusive and shall be described in a statement filed by the Corporation with the stock transfer or conversion agent, as appropriate). Notwithstanding the foregoing, any adjustments to the Conversion Price with respect to the preferred stock purchase rights (the "Rights") of the Corporation associated with the shares of Common Stock, which Rights are governed by a Rights Agreement dated as of February 13, 2002, as amended (the "Rights Agreement"), or similar rights or warrants adopted or issued subsequent to the date hereof shall be made when such Rights or similar rights or warrants are exercised. If after the Distribution Date (as defined in the Rights Agreement or a similar date defined in a similar agreement), holders converting shares of Convertible Preferred Stock are not entitled to receive the Rights or similar rights or warrants which would otherwise be attributable (but for the date of conversion) to the shares of Common Stock received upon such conversion, then adjustment to the Conversion Price shall be made under this subsection (ii) as if the Rights or similar rights or warrants were then issued to holders of Common Stock. If such an adjustment is made and the Rights or similar rights or warrants are later redeemed, invalidated or terminated, then a corresponding reversing adjustment shall be made to the Conversion Price, on an equitable basis, to take account of such event. However, the Corporation may elect to provide that such shares of Common Stock issuable upon conversion of the Convertible Preferred Stock, whether or not issued after the Distribution Date for such Rights or such similar date for such similar rights or warrants, will be accompanied by the Rights or such similar rights or warrants which would otherwise be attributable (but for the date of conversion) to such shares of Common Stock, in which event the preceding two sentences shall not apply. -9- (iii) In case the Corporation shall, by dividend or otherwise, distribute to all holders of its outstanding Common Stock or capital stock (other than Common Stock), evidences of its indebtedness or assets (including securities and cash, but excluding any regular periodic cash dividend of the Corporation and dividends or distributions payable in stock for which adjustment is made pursuant to subsection (i) of this Section 6(d)) or rights or warrants to subscribe for or purchase securities of the Corporation (excluding those referred to in subsection (ii) of this Section 6(d)), then in each such case the Conversion Price shall be adjusted so that the same shall equal the price determined by multiplying the Conversion Price in effect immediately prior to the record date of such distribution by a fraction of which the numerator shall be the current market price per share as determined pursuant to subsection (iv) of this Section 6(d) of the Common Stock less the fair market value on such record date (as determined by the Board of Directors, whose determination shall be conclusive and shall be described in a statement filed by the Corporation with the stock transfer or conversion agent, as appropriate) of the portion of the capital stock or assets or the evidences of indebtedness or assets so distributed to the holder of one share of Common Stock or of such subscription rights or warrants applicable to one share of Common Stock, and of which the denominator shall be such current market price per share of Common Stock. Such adjustment shall become effective immediately after the record date for the determination of stockholders entitled to receive such distribution. (iv) For the purpose of any computation under subsections (ii) and (iii) of this Section 6(d), the current market price per share of Common Stock on any date shall be deemed to be the average of the closing price (as defined in Section 5) for the shorter of (A) 30 consecutive trading days (as defined in Section 5) ending on the last full trading day prior to the Time of Determination or (B) the period commencing on the date next succeeding the first public announcement of the issuance of such rights or warrants or such distribution through such last full trading day prior to the Time of Determination. For purposes of the foregoing, the term "Time of Determination" shall mean the time and date of the earlier of (I) the record date for determining stockholders entitled to receive the rights, warrants or distributions referred to in Section 6(d)(ii) and (iii) or (II) the commencement of "ex-dividend" trading on the exchange or market referred to in the definition of "closing price." (v) In any case in which this Section 6(d) shall require that an adjustment be made immediately following a record date or an effective date, the Corporation may elect to defer (but only until the filing by the Corporation with the stock transfer or conversion agent, as the case may be, of the certificate required by subsection (vii) of this Section 6(d)) issuing to the holder of any share of Convertible Preferred Stock converted after such record date or effective date the shares of Common Stock issuable upon such conversion over and above the shares of Common Stock issuable upon such conversion on the basis of the Conversion Price prior to adjustment, and paying to such holder any amount of cash in lieu of a fractional share. (vi) No adjustment in the Conversion Price shall be required to be made unless such adjustment would require an increase or decrease of at least 1% of such price; provided, however, that any adjustments which by reason of this subsection (vi) are not -10- required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Section 6(d) shall be made to the nearest cent or to the nearest 1/1000th of a share, as the case may be. Anything in this Section 6(d) to the contrary notwithstanding, the Corporation shall be entitled to make such reduction in the Conversion Price, in addition to those required by this Section 6(d), as it in its discretion shall determine to be advisable in order that any stock dividend, subdivision of shares, distribution of rights to purchase stock or securities, or distribution of securities convertible into or exchangeable for stock hereafter made by the Corporation to its stockholders shall not be taxable to the recipients. Except as set forth in subsections (i), (ii) and (iii) above, the Conversion Price shall not be adjusted for the issuance of Common Stock, or any securities convertible into or exchangeable for Common Stock or carrying the right to purchase any of the foregoing, in exchange for cash, property or services. (vii) Whenever the Conversion Price is adjusted as herein provided, (A) the Corporation shall promptly file with the stock transfer or conversion agent, as appropriate, a certificate setting forth the Conversion Price after such adjustment and a brief statement of the facts requiring such adjustment and the manner of computing the same, which certificate shall be conclusive evidence of the correctness of such adjustment, and (B) the Corporation shall also mail or cause to be mailed by first class mail, postage prepaid, as soon as practicable to each holder of record of shares of Convertible Preferred Stock a notice stating that the Conversion Price has been adjusted and setting forth the adjusted Conversion Price. The stock transfer or conversion agent, as the case may be, shall not be under any duty or responsibility with respect to the certificate required by this subsection (vii) except to exhibit the same to any holder of shares of Convertible Preferred Stock who requests to inspect it. (viii) In the event that at any time, as a result of an adjustment made pursuant to subsection (i) of this Section 6(d), the holder of any share of Convertible Preferred Stock thereafter surrendered for conversion shall become entitled to receive any shares of the Corporation other than shares of Common Stock, thereafter the Conversion Price of such other shares so receivable upon conversion of any share of Convertible Preferred Stock shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to Common Stock contained in this Section. (ix) The Corporation from time to time may decrease the Conversion Price by any amount for any period of time if the period is at least 20 days and if the decrease is irrevocable during the period. Whenever the Conversion Price is so decreased, the Corporation shall mail to holders of record of shares of Convertible Preferred Stock a notice of the decrease at least 15 days before the date the decreased Conversion Price takes effect, and such notice shall state the decreased Conversion Price and the period it will be in effect. -11- (e) Notice to Holders Prior to Certain Corporate Actions. In case: (i) the Corporation shall take any action which would require an adjustment in the Conversion Price pursuant to Section 6(d)(iii); or (ii) the Corporation shall authorize the granting to the holders of its Common Stock generally of rights or warrants to subscribe for or purchase any shares of stock of any class or of any other rights; or (iii) there shall be any reorganization or reclassification of the Common Stock (other than a subdivision or combination of the outstanding Common Stock and other than a change in the par value of the Common Stock), or any consolidation or merger to which the Corporation is a party or any statutory exchange of securities with another corporation and for which approval of any stockholders of the Corporation is required, or any sale or transfer of all or substantially all of the assets of the Corporation; or (iv) there shall be a voluntary or involuntary dissolution, liquidation or winding-up of the Corporation; then in each such case the Corporation shall cause to be given to the holders of shares of Convertible Preferred Stock and the stock transfer or conversion agent, as appropriate, as promptly as possible, but in any event at least 20 days prior to the applicable date hereinafter specified, a notice stating (i) the date on which a record is to be taken for the purpose of such action or granting of rights or warrants, or, if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such distribution, rights or warrants are to be determined, or (ii) the date on which such reorganization, reclassification, consolidation, merger, statutory exchange, sale, transfer, dissolution, liquidation or winding-up is expected to become effective or occur, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their shares of Common Stock for securities, cash or other property deliverable upon such reorganization, reclassification, consolidation, merger, statutory exchange, sale, transfer, dissolution, liquidation or winding-up. Failure to give such notice or any defect therein shall not affect the legality or validity or the proceedings described in subsection (i), (ii), (iii) or (iv) of this Section 6(e). (f) Reservation of Shares of Common Stock. The Corporation covenants that it will at all times reserve and keep available, free from preemptive rights, out of the aggregate of its authorized but unissued shares of Common Stock or its issued shares of Common Stock held in its treasury, or both, for the purpose of effecting conversions of shares of Convertible Preferred Stock, the full number of shares of Common Stock deliverable upon the conversion of all outstanding shares of Convertible Preferred Stock not theretofore converted and on or before (and as a condition of) taking any action that would cause an adjustment of the Conversion Price resulting in an increase in the number of shares of Common Stock deliverable upon conversion above the number thereof previously reserved and available therefor, the Corporation shall take all such action so required. For purposes of this Section 6(f), the number of shares of Common Stock which shall be deliverable upon the conversion of all outstanding shares of Convertible Preferred Stock shall be computed as if at the time of computation all outstanding shares of Convertible Preferred Stock were held by a single holder. -12- Before taking any action which would cause an adjustment reducing the Conversion Price below the then par value (if any) of the shares of Common Stock deliverable upon conversion of the shares of Convertible Preferred Stock, the Corporation shall take any corporate action which may, in the opinion of its counsel, be necessary in order that the Corporation may validly and legally issue fully paid and non-assessable shares of Common Stock at such adjusted Conversion Price. (g) Transfer Taxes, Etc. The Corporation shall pay any and all documentary stamp, issue or transfer taxes, and any other similar taxes payable in respect of the issue or delivery of shares of Common Stock upon conversions of shares of Convertible Preferred Stock pursuant hereto; provided, however, that the Corporation shall not be required to pay any tax which may be payable in respect of any transfer involved in the issue or delivery of shares of Common Stock in a name other than that of the holder of the shares of Convertible Preferred Stock to be converted and no such issue or delivery shall be made unless and until the person requesting such issue or delivery 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. (h) Consolidation or Merger or Sale of Assets. Notwithstanding any other provision herein to the contrary, in case of any consolidation or merger to which the Corporation is a party (other than a merger or consolidation in which the Corporation is the continuing corporation and in which the Common Stock outstanding immediately prior to the merger or consolidation is not exchanged for cash, or the securities or other property of another corporation), or in case of any sale or transfer to another corporation of the property of the Corporation as an entirety or substantially as an entirety, or in the case of any statutory exchange of securities with another corporation (other than in connection with a merger or acquisition), then lawful provision shall be made by the corporation formed by such consolidation or the corporation whose securities, cash or other property will immediately after the merger or consolidation be owned, by virtue of the merger or consolidation, by the holders of Common Stock immediately prior to the merger or consolidation, or the corporation which shall have acquired such assets or securities of the Corporation (collectively the "Formed, Surviving or Acquiring Corporation"), as the case may be, providing that the holder of each share of Convertible Preferred Stock then outstanding shall have the right thereafter to convert such share into the kind and amount of securities, cash or other property receivable upon such consolidation, merger, statutory exchange, sale or transfer by a holder of the number of shares of Common Stock into which such share of Convertible Preferred Stock might have been converted immediately prior to such consolidation, merger, statutory exchange, sale or transfer assuming such holder of Common Stock did not exercise his rights of election, if any, as to the kind or amount of securities, cash or other property receivable upon such consolidation, merger, statutory exchange, sale or transfer (provided that, if the kind or amount of securities, cash or other property receivable upon such consolidation, merger, statutory exchange, sale or transfer is not the same for each share of Common Stock in respect of which such rights of election shall not have been exercised ("non-electing share"), then for the purposes of this Section 6(h) the kind and amount of securities, cash or other property receivable upon such consolidation, merger, statutory exchange, sale or transfer for each non-electing share shall be deemed to be the kind and amount so receivable per share by a plurality of the non-electing shares). The Formed, Surviving or Acquiring Corporation, as the case may be, shall make provision in its certificate or articles of incorporation or other constituent documents to the end that the provisions set forth in -13- this Section 6(h) shall thereafter correspondingly be made applicable, as nearly as may reasonably be, in relation to any shares of stock or other securities or property thereafter deliverable on the conversion of the Convertible Preferred Stock. The above provisions of this Section 6(h) shall similarly apply to successive consolidations, mergers, statutory exchanges, sales or transfers. (i) Covenant as to Common Stock. The Corporation covenants that all shares of Common Stock which may be delivered upon conversions of shares of Convertible Preferred Stock will upon delivery be duly and validly issued and fully paid and non-assessable, free of all liens and charges and not subject to any preemptive rights. The Corporation covenants that if any shares of Common Stock to be provided for the purpose of conversion of shares of Convertible Preferred Stock hereunder require registration with or approval of any governmental authority under any Federal or State law before such shares may be validly issued upon conversion, the Corporation will in good faith and as expeditiously as possible endeavor to secure such registration or approval, as the case may be. The Corporation further covenants that if at any time the Common Stock shall be listed on the New York Stock Exchange or any other national securities exchange, the Corporation will, if permitted by the rules of such exchange, list and keep listed so long as the Common Stock shall be so listed on such exchange, all Common Stock issuable upon conversion of the shares of Convertible Preferred Stock. Section 7. Voting Rights. (a) General. The holders of Convertible Preferred Stock shall not have any voting rights except as set forth below or as otherwise from time to time required by law. In connection with any right to vote, each holder of Convertible Preferred Stock will have one vote for each share held. Any shares of Convertible Preferred Stock held by the Corporation or any entity controlled by the Corporation shall not have voting rights hereunder and shall not be counted in determining the presence of a quorum. (b) General Voting Rights. The holders of Convertible Preferred Stock shall be entitled to vote together with the holders of Common Stock, as a single class, on all matters submitted to the stockholders of the Corporation. (c) Default Voting Rights. Whenever dividends on the Convertible Preferred Stock shall be in arrears in an amount equal to at least six quarterly dividends (whether or not consecutive), (i) the number of members of the Board of Directors of the Corporation shall be increased by two, effective as of the time of election of such directors as hereinafter provided, and (ii) the holders of the Convertible Preferred Stock (voting separately as a class with all other affected classes or series of the Parity Dividend Stock upon which like voting rights have been conferred and are exercisable) will have the exclusive right to vote for and elect such two additional directors of the Corporation at any meeting of stockholders of the Corporation at which directors are to be elected held during the period such dividends remain in arrears. The right of the holders of the Convertible Preferred Stock to vote for such two additional directors shall terminate when all accrued and unpaid dividends on the Convertible Preferred Stock have been declared and paid or set apart for payment. The term of office of all directors so elected -14- shall terminate immediately upon the termination of the right of the holders of the Convertible Preferred Stock and such Parity Dividend Stock to vote for such two additional directors. The foregoing right of the holders of the Convertible Preferred Stock with respect to the election of two directors may be exercised at any annual meeting of stockholders or at any special meeting of stockholders held for such purpose. If the right to elect directors shall have accrued to the holders of the Convertible Preferred Stock more than 90 days preceding the date established for the next annual meeting of stockholders, the President of the Corporation shall, within 20 days after the delivery to the Corporation at its principal office of a written request for a special meeting signed by the holders of at least ten percent (10%) of the Convertible Preferred Stock then outstanding, call a special meeting of the holders of the Convertible Preferred Stock to be held within 60 days after the delivery of such request for the purpose of electing such additional directors. The holders of the Convertible Preferred Stock and any Parity Dividend Stock referred to above voting as a class shall have the right to remove without cause at any time and replace any directors such holders have elected pursuant to this Section 7. (d) Class Voting Rights. So long as the Convertible Preferred Stock is outstanding, the Corporation shall not, without the affirmative vote or consent of the holders of at least 66 2/3 percent of all outstanding Convertible Preferred Stock (unless the vote or consent of a greater percentage is required by applicable law or the Restated Articles of Incorporation of the Corporation), voting separately as a class, (i) amend, alter or repeal (by merger, consolidation or otherwise) any provision of the Restated Articles of Incorporation or the Bylaws of the Corporation, as amended, so as to affect adversely the relative rights, preferences, qualifications, limitations or restrictions of the Convertible Preferred Stock, (ii) authorize or issue, or increase the authorized amount of, any additional class or series of stock, or any security convertible into stock of such class or series, ranking prior to the Convertible Preferred Stock in respect of the payment of dividends or upon liquidation, dissolution or winding up of the Corporation or (iii) effect any reclassification of the Convertible Preferred Stock. A class vote on the part of the Convertible Preferred Stock shall, without limitation, specifically not be deemed to be required (except as otherwise required by law or resolution of the Corporation's Board of Directors) in connection with: (a) the authorization, issuance or increase in the authorized amount of any shares of any other class or series of stock that ranks junior to, or on a parity with, the Convertible Preferred Stock in respect of the payment of dividends and upon liquidation, dissolution or winding up of the Corporation; or (b) the authorization, issuance or increase in the amount of any notes, bonds, mortgages, debentures or other obligations of the Corporation not convertible into or exchangeable, directly or indirectly, for stock ranking prior to the Convertible Preferred Stock in respect of the payment of dividends or upon liquidation, dissolution or winding up of the Corporation. Section 8. Outstanding Shares. For purposes of this Certificate of Resolution, all shares of Convertible Preferred Stock shall be deemed outstanding except (i) from the date fixed for redemption pursuant to Section 5, all shares of Convertible Preferred Stock that have been so called for redemption under Section 5 if shares of Common Stock and funds necessary for payment of the redemption price have been irrevocably set apart; (ii) from the date of surrender of certificates representing shares of Convertible Preferred Stock, all shares of -15- Convertible Preferred Stock converted into Common Stock; and (iii) from the date of registration of transfer, all shares of Convertible Preferred Stock held of record by the Corporation or any subsidiary of the Corporation. Section 9. Status of Acquired Shares. Shares of Convertible Preferred Stock redeemed by the Corporation, received upon conversion pursuant to Section 6, or otherwise acquired by the Corporation will be restored to the status of authorized and unissued shares of Preferred Stock, without designation as to series, and may thereafter be issued, but not as shares of Convertible Preferred Stock. Section 10. Preemptive Rights. The Convertible Preferred Stock is not entitled to any preemptive or subscription rights in respect of any securities of the Corporation. Section 11. Severability of Provisions. Whenever possible, each provision hereof shall be interpreted in a manner as to be effective and valid under applicable law, but if any provision hereof is held to be prohibited by or invalid under applicable law, such provision shall be ineffective only to the extent of such prohibition or invalidity, without invalidating or otherwise adversely affecting the remaining provisions hereof. If a court of competent jurisdiction should determine that a provision hereof would be valid or enforceable if a period of time were extended or shortened or a particular percentage were increased or decreased, then such court may make such change as shall be necessary to render the provision in question effective and valid under applicable law. -16- IN WITNESS WHEREOF, the Corporation has caused this certificate to be signed by its President and attested to by its Secretary this ___ day of __________, 2002.
