Cumulative Dividend Rights. The holders of the $.70 Preferred Stock shall be entitled to receive, when and as declared by the Board of Directors, out of funds legally available for the purpose, cumulative cash dividends at the rate of $.70 per share per annum, payable quarterly on January 15, April 15, July 15 and October 15 in each year. Dividends on the $.70 Preferred Stock shall be cumulative from the dividend payment date next preceding the date on which the $.70 Preferred Stock is issued.

Distribution on Liquidation. If, upon any such liquidation dissolution or winding up, the assets of the corporation distributable among the holders of the $.70 Preferred Stock shall be insufficient to pay to them in full the preferential amounts specified above, then such assets, or the proceeds thereof, shall be distributed among the holders of the $.70 Preferred Stock ratably in proportion to the amounts which would be payable to them, respectively, if such preferential amounts were paid to them in full. 4. Required and Optional Redemptions. 4.1. Required Redemptions. On June 1, 1989 and on each June 1 thereafter until all of the $.70 Preferred Stock shall have been redeemed, the corporation shall redeem the number of shares of the $.70 Preferred Stock specified in the following table (subject, however, to the provisions of section 4.3 hereof), upon the payment in cash of an amount equal to $10.00 per share, together with a sum equal to Full Cumulative Dividends on the $.70 Preferred Stock being redeemed to the date of redemption: Number of Shares Date of Redemption to be Redeemed June 1, 1989 45,000 June 1, 1990 40,000 June 1, 1991 40,000 June 1, 1992 40,000 June 1, 1993 All shares then remaining outstanding.

As used in the foregoing clause (b), the term "Securities Act" shall have the meaning specified in section 10.2 of the Purchase Agreements. 4.3. Additional Redemptions. Notwithstanding any other provision hereof, if Section 302(b)(2) of the Internal Revenue Code as in effect on April 15, 1978 (or any similar provision of the tax laws of the United States of America in effect thereafter) shall not be applicable to any redemption required by section 4.1 or to any redemption proposed to be made under section 4.2, the corporation shall, at the time of such redemption, concurrently redeem such additional number of shares of the $.70 Preferred Stock as shall, in the opinion of the firm of independent public accountants referred to below, be required so that said Section 302(b)(2) (or such similar provision) shall be applicable to such redemption. The corporation shall furnish to each holder of the $.70 Preferred Stock, at least 30 days prior to the date fixed for any redemption under section 4.1 or section 4.2, a certificate of its principal financial officer certifying that said Section 302(b)(2) (or such similar provision) will be applicable to such redemption and showing in reasonable detail all computations required to demonstrate such applicability, together with a certificate of a firm of independent public accountants of recognized national standing selected by the corporation certifying to such applicability. 4.4. Notice of Optional Redemptions. In the case of each optional redemption under section 4.2 hereof, the corporation shall give written notice thereof to each holder of the $.70 Preferred Stock not less than 30 nor more than 60 days prior to the date fixed for such redemption, in each case specifying such date, the aggregate number of shares of the $.70 Preferred Stock to be redeemed on such date and the number of shares of $.70 Preferred Stock held by such holder to be redeemed on such date. Such notice shall be given by delivering or mailing the same to each such holder at the address of such holder as it appears on the corporation's stock records. 4.5. Allocation of Partial Redemptions. If less than all of the outstanding shares of the $.70 Preferred Stock are to be redeemed pursuant to sections 4.1, 4.2 or 4.3 hereof, the shares of the $.70 Preferred Stock to be redeemed shall be allocated in whole shares among all of the holders ratably in proportion, as nearly as practicable, to the respective numbers of shares held by such holders, with adjustments, to the extent practicable, to compensate for any prior redemptions not allocated exactly in such proportion. 4.6. Effect of Redemption. Upon the date fixed for any redemption of the $.70 Preferred Stock, and upon payment by the corporation of the amounts payable on redemption as provided herein, all shares of the $.70 Preferred Stock redeemed shall be deemed to be no longer outstanding for any purpose, whether or not the certificates for such shares shall have been surrendered for cancellation, and all rights with respect to such shares shall thereupon cease, except only the right of the holders of such shares to receive the amounts payable upon the redemption thereof. All shares of the $.70 Preferred Stock redeemed by the corporation shall be retired and cancelled and shall not be reissued. 5. Conversion. 5.1. Conversion Privilege. Any shares of the $.70 Preferred Stock may, at the election of the holder thereof, at any time prior to the close of business on May 31, 1993 be converted, at the conversion price per share of Common Stock of $8.50, as adjusted and readjusted from time to time in accordance with section 5.4 hereof (such conversion price, as so adjusted and readjusted and in effect at any time, being herein called the "Conversion Price"), into the number of fully paid and non assessable shares of Common Stock determined by dividing (a) the aggregate par value of the shares of the $.70 Preferred Stock to be so converted, multiplied by 10, by (b) the Conversion Price in effect at the time of such conversion. 5.2. Manner of Conversion, etc. The certificate or certificates for any shares of the $.70 Preferred Stock to be converted shall be surrendered at the office or agency maintained for such purpose pursuant to section 5.9 hereof, duly endorsed, or accompanied by proper instruments of transfer, to the corporation or in blank, and accompanied by written notice to the corporation of the holder's election to make such conversion and of the name or names in which the certificate or certificates for shares of Common Stock are to be issued. The right to convert any shares of the $.70 Preferred Stock called for redemption shall terminate at the close of business on the last full business day next preceding the date fixed for such redemption. Upon conversion of any shares of the $.70 Preferred Stock, the corporation shall pay to the holder thereof a sum equal to Full Cumulative Dividends thereon to the date of conversion. Each conversion shall be deemed to have been effected as of the close of business on the date on which such certificate or certificates shall have been so surrendered to such agency, and at such time the rights of the holder of $.70 Preferred Stock as such shall, to the extent of the number of shares thereof converted, cease, 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 thereof. 5.3. Delivery of Stock Certificates; Fractional Shares. As promptly as practicable after the conversion of any $.70 Preferred Stock, and in any event within 20 days thereafter, the corporation at its expense (including the payment by it of any applicable issue taxes) will issue and deliver to the holder of such $.70 Preferred Stock, or as such holder (upon payment by such holder of any applicable transfer taxes) may direct, a certificate or certificates for the number of full shares of Common Stock issuable upon such conversion, plus, in lieu of any fractional share to which such holder would otherwise be entitled, cash equal to such fraction multiplied by the then current Market Price of one full share, determined as provided in clause (viii) of subdivision (b) of section 5.4 hereof. 5.4. Adjustment of Conversion Price for Diluting Issues, Distributions. (a) Adjustment for Sales Below Conversion Price, etc. If and whenever after April 15, 1978 the corporation shall issue or sell any shares of its Common Stock for a consideration per share less than the Conversion Price in effect immediately prior to the time of such issue or sale, and/or the corporation shall issue or sell any shares of its Common Stock (except on conversion of $.70 Preferred Stock) for a consideration per share less than the Market Price on the date of such issue or sale, then, forthwith upon such issue or sale, the Conversion Price shall be reduced to the lower of the prices (calculated to the nearest cent) determined as follows: (i) by dividing (A) an amount equal to the sum of (1) the number of shares of Common Stock outstanding immediately prior to such issue or sale multiplied by the then existing Conversion Price, and (2) the consideration, if any, received by the corporation upon such issue or sale, by (B) the total number of shares of Common Stock outstanding immediately after such issue or sale; and (ii) by multiplying the Conversion Price in effect immediately prior to the time of such issue or sale by a fraction, the numerator of which shall be the sum of (A) the number of shares of Common Stock outstanding immediately prior to such issue or sale multiplied by the Market Price immediately prior to such issue or sale plus (B) the consideration received by the corporation upon such issue or sale, and the denominator of which shall be the product of (C) the total number of shares of Common Stock outstanding immediately after such issue or sale, multiplied by (D) the Market Price immediately prior to such issue or sale. (b) For the purposes of subdivision (a) above, the following clauses (i) to (x), inclusive, shall also be applicable: (i) Issuance of Rights or Options. In case at any time the corporation shall grant (whether directly or by assumption in a merger or otherwise) any rights to subscribe for or to purchase, or any options for the purchase of, Common Stock or any stock or securities convertible into or exchangeable for Common Stock (such convertible or exchangeable stock or securities being herein called "Convertible Securities") whether or not such rights or options or the right to convert or exchange any such Convertible Securities are immediately exercisable, and the price per share for which Common Stock is issuable upon the exercise of such rights or options or upon conversion or exchange of such Convertible Securities (determined by dividing (A) the total amount, if any, received or receivable by the corporation as consideration for the granting of such rights or options, plus the minimum aggregate amount of additional consideration payable to the corporation upon the exercise of all such rights or options, plus, in the case of such rights or options which relate to Convertible Securities, the minimum aggregate amount of additional consideration, if any, payable upon the issue or sale of such Convertible Securities and upon the conversion or exchange thereof, by (B) the total maximum number of shares of Common Stock issuable upon the exercise of such rights or options or upon the conversion or exchange of all such Convertible Securities issuable upon the exercise of such rights or options) shall be less than the Conversion Price in effect immediately prior to the time of the granting of such rights or options (or less than the Market Price, determined as of the date of granting such rights or options, as the case may be), then the total maximum number of shares of Common Stock issuable upon the exercise of such rights or options or upon conversion or exchange of the total maximum amount of such Convertible Securities issuable upon the exercise of such rights or options shall (as of the date of granting of such rights or options) be deemed to be outstanding and to have been issued for such price per share. Except as provided in clause (iii) below, no further adjustments of the Conversion Price shall be made upon the actual issue of such Common Stock or of such Convertible Securities upon exercise of such rights or options or upon the actual issue of such Common Stock upon conversion or exchange of such Convertible Securities. (ii) Issuance of Convertible Securities. In case the corporation shall issue (whether directly or by assumption in a merger or otherwise) or sell any Convertible Securities, whether or not the rights to exchange or convert thereunder are immediately exercisable, and the price per share for which Common Stock is issuable upon such conversion or exchange (determined by dividing (A) the total amount received or receivable by the corporation as consideration for the issue or sale of such Convertible Securities, plus the minimum aggregate amount of additional consideration, if any, payable to the corporation upon the conversion or exchange thereof, by (B) the total maximum number of shares of Common Stock issuable upon the conversion or exchange of all such Convertible Securities) shall be less than the Conversion Price in effect immediately prior to the time of such issue or sale (or less than the Market Price, determined as of the date of such issue or sale of such Convertible Securities, as the case may be), then the total maximum number of shares of Common Stock issuable upon conversion or exchange of all such Convertible Securities shall (as of the date of the issue or sale of such Convertible Securities) be deemed to be outstanding and to have been issued for such price per share, provided that (1) except as provided in clause (iii) below, no further adjustments of the Conversion Price shall be made upon the actual issue of such Common Stock upon conversion or exchange of such Convertible Securities, and (2) if any such issue or sale of such Convertible Securities is made upon exercise of any rights to subscribe for or to purchase or any option to purchase any such Convertible Securities for which adjustments of the Conversion Price have been or are to be made pursuant to other provisions of this subdivision (b), no further adjustment of the Conversion Price shall be made by reason of such issue or date. (iii) Change in Option Price or Conversion Rate. Upon the happening of any of the following events, namely, if the purchase price provided for in any rights or options referred to in clause (i) of this subdivision (b), the additional consideration, if any, payable upon the conversion or exchange of Convertible Securities referred to in clause (i) or clause (ii) of this subdivision (b), or the rate at which any Convertible Securities referred to in clause (i) or clause (ii) of this subdivision (b) are convertible into or exchangeable for Common Stock shall change (other than under or by reason of provisions designed to protect against dilution), the Conversion Price in effect at the time of such event shall forthwith be readjusted to the Conversion Price which would have been in effect at such time had such rights, options or Convertible Securities still outstanding provided for such changed purchase price, additional consideration or conversion rate, as the case may be, at the time initially granted, issued or sold; and on the expiration of any such option or right or the termination of any such right to convert or exchange such Convertible Securities, the Conversion Price then in effect hereunder shall forthwith be increased to the Conversion Price which would have been in effect at the time of such expiration or termination had such right, option or Convertible Security, to the extent outstanding immediately prior to such expiration or termination, never been issued, and the Common Stock issuable thereunder shall no longer be deemed to be outstanding. If the purchase price provided for in any such right or option referred to in clause (i) of this subdivision (b) or the rate at which any Convertible Securities referred to in clause (i) or clause (ii) of this subdivision (b) are convertible into or exchangeable for Common Stock, shall decrease at any time under or by reason of provisions with respect thereto designed to protect against dilution, then in case of the delivery of Common Stock upon the exercise of any such right or option or upon conversion or exchange of any such Convertible Security, the Conversion Price then in effect hereunder shall forthwith be adjusted to such respective amount as would have obtained had such right, option or Convertible Security never been issued as to such Common Stock and had adjustments been made upon the issuance of the shares of Common Stock delivered as aforesaid, but only if as a result of such adjustment the Conversion Price then in effect hereunder is thereby decreased. (iv) Stock Dividends. In case the corporation shall declare a dividend or snake any other distribution upon any stock of the corporation payable in Common Stock or Convertible Securities, any Common Stock or Convertible Securities, as the case may be, issuable in payment of such dividend or distribution shall be deemed to have been issued or sold without consideration. (v) Consideration for Stock. In case any shares of Common Stock or Convertible Securities or any rights or options to purchase any such Common Stock or Convertible Securities shall be issued or sold for cash the consideration received therefor shall be deemed to be the amount received by the corporation therefor, without deduction therefrom of any expenses incurred or any underwriting commissions or concessions paid or allowed by the corporation in connection therewith. In case any shares of Common Stock or Convertible Securities or any rights or options to purchase any such Common Stock or Convertible Securities shall be issued or sold for a consideration other than cash, the amount of the consideration other than cash received by the corporation shall be deemed to be the fair value of such consideration as determined in good faith by the Board of Directors of the Corporation, without deduction of any expenses incurred or any underwriting commissions or concessions paid or allowed by the corporation in connection therewith. In case any shares of Common Stock or Convertible Securities or any rights or options to purchase such Common Stock or Convertible Securities shall be issued in connection with any merger or consolidation in which the corporation is the surviving corporation, the amount of consideration therefor shall be deemed to be the fair value as determined by the Board of Directors of the corporation of such portion of the assets and business of the non-surviving corporation or corporations as such Board shall determine to be attributable to such Common Stock, Convertible Securities, rights or options, as the case may be. In the event of any consolidation or merger of the corporation in which the corporation is not the surviving corporation or in the event of any sale of all or substantially all of the assets of the corporation for stock or other securities of any corporation, the corporation shall be deemed to have issued a number of shares of its Common Stock for stock or securities of the other corporation computed on the basis of the actual exchange ratio on which the transaction was predicated and for a consideration equal to the fair market value on the date of such transaction of such stock or securities of the other corporation. (vi) Record Date. In case the corporation shall take a record of the holders of its Common Stock for the purpose of entitling them (A) to receive a dividend or other distribution payable in Common Stock or in Convertible Securities, or (B) to subscribe for or purchase Common Stock or Convertible Securities, then such record date shall be deemed to be the date of the issue or sale of the shares of Common Stock deemed to have been issued upon the declaration of such dividend or the making of such other distribution or the date of the granting of such right of subscription or purchase, as the case may be. (vii) Treasury Shares. The number of shares of Common Stock outstanding at any given time shall not include shares owned or held by or for the account of the corporation, and the disposition of any such shares shall be considered an issue or sale of Common Stock for the purposes of this subdivision (b). (viii) Definition of Market Price. "Market Price" shall mean in the case of any trading day the average of the closing prices of the Common Stock sales on all exchanges on which the Common Stock may at the time be listed, or, if there shall have been no sales on any such exchange on any such day, the average of the bid and asked prices at the end of such day, or, if the Common Stock shall not be so listed, the average of the bid and asked prices at the end of such day in the over-the-counter market, in each such case (except for the purposes of section 4.2 hereof) averaged over a period of 20 consecutive business days prior to the day as of which "market price" is being determined. If at any time the Common Stock is not listed on any exchange or quoted in the over-the-counter market, the "Market Price" shall be deemed to be the higher of (A) the book value thereof as determined by any firm of independent public accountants of recognized national standing selected by the Board of Directors of the corporation as at the last day of any month ending within 60 days preceding the date as of which the determination is to be made or (B) the fair value thereof determined in good faith by the Board of Directors of the corporation as of a date which is within 15 days of the date as of which the determination is to be made. (ix) Determination of Market Price under Certain Circumstances. Anything herein to the contrary notwithstanding, in case the corporation shall issue any shares of Common Stock or Convertible Securities in connection with the acquisition by the corporation of the stock or assets of any other corporation or the merger of any other corporation into the corporation under circumstances where on the date of the issuance of such shares of Common Stock or Convertible Securities the consideration received for such Common Stock or deemed to have been received for the Common Stock into which such Convertible Securities are convertible is less than the Market Price of the Common Stock, but on the date the number of shares of Common Stock or Convertible Securities (or in the case of Convertible Securities other than stock, the aggregate principal amount of Convertible Securities) was determined the consideration received for such Common Stock or deemed to have been received for the Common Stock into which such Convertible Securities are convertible would not have been less than the Market Price thereof, such shares of Common Stock shall not be deemed to have been issued for less than the Market Price of the Common Stock. (x) Determination of Consideration in Connection with Certain Acquisitions. Anything in clause (v) of this subdivision (b) to the contrary notwithstanding, in the case of an acquisition where all or part of the purchase price is payable in Common Stock or Convertible Securities but is stated as a dollar amount, where the corporation upon making the acquisition pays only part of a maximum dollar purchase price which is payable in Common Stock or Convertible Securities and where the balance of such purchase price is deferred or is contingently payable under a formula related to earnings over a period of time, (A) the consideration received for any Common Stock or Convertible Securities delivered at the time of the acquisition shall be deemed to be such part of the total consideration as the portion of the dollar purchase price then paid in Common Stock or Convertible Securities bears to the total maximum dollar purchase price payable in Common Stock or Convertible Securities, and (B) in connection with each issuance of additional Common Stock or Convertible Securities pursuant to the terms of the agreement relating to such acquisition, the consideration received shall be deemed to be such part of the total consideration as the portion of the dollar purchase price then and theretofore paid in Common Stock or Convertible Securities bears to the total maximum dollar purchase price payable in Common Stock or Convertible Securities multiplied by a fraction, the numerator of which shall be the number of shares (or in the case of Convertible Securities other than stock, the aggregate principal amount) then issued and the denominator of which shall be the total number of shares (or in the case of Convertible Securities other than stock, the aggregate principal amount) then and theretofore issued under such acquisition agreement. If it is determined that any part of the deferred or contingent portion of such purchase price shall not be payable, the Conversion Price then in effect hereunder shall forthwith be readjusted to such Conversion Price as would have obtained (l) had the adjustment made in connection with such acquisition been made upon the basis of the issuance of only the number of shares of Common Stock or Convertible Securities actually issued in connection with such acquisition, and (2) had adjustments been made on the basis of the Conversion Price as adjusted in clause (1) for all issues or sales (as prices which would have affected such adjusted Conversion Price) of Common Stock or rights, options or Convertible Securities made after such acquisition. In the event that only a part of the purchase price for an acquisition is paid in Common Stock or Convertible Securities in the manner referred to in this clause (x), the term "total consideration" as used in this clause (x) shall mean that part of the aggregate consideration as is fairly allocable to the purchase price paid in Common Stock or Convertible Securities in the manner referred to in this clause (x), as determined by the Board of Directors of the corporation. (c) Adjustment for Certain Special Dividends. In case the corporation shall declare a dividend upon the Common Stock payable otherwise than out of consolidated earnings or consolidated earned surplus, determined in accordance with generally accepted accounting principles, including the making of appropriate deductions for minority interests, if any, in Subsidiaries, and otherwise than in Common Stock or Convertible Securities, the Conversion Price in effect immediately prior to the declaration of such dividend shall be reduced by an amount equal, in the case of a dividend in cash, to the amount thereof payable per share of the Common Stock or, in the case of any other dividend, to the fair value thereof per share of the Common Stock as determined by the Board of Directors of the corporation. For the purposes of the foregoing a dividend other than in cash shall be considered payable out of earnings or surplus (other than revaluation or paid-in surplus) only to the extent that such earnings or surplus are charged an amount equal to the fair value of such dividend as determined by the Board of Directors of the corporation. Such reductions shall take effect as of the date on which a record is taken for the purpose of such dividend, or, if a record is not taken the date as of which the holders of Common Stock of record entitled to such dividend are to be determined. (d) Subdivision or Combination of Stock. In case the corporation shall at any time subdivide its outstanding shares of Common Stock into a greater number of shares, the Conversion Price in effect immediately prior to such subdivision shall be proportionately reduced, and conversely, in case the outstanding shares of Common Stock of the corporation shall be combined into a smaller number of shares, the Conversion Price in effect immediately prior to such Combination shall be proportionately increased. (e) Reorganization, Reclassification, Consolidation, Merger or Sale. If any capital reorganization or reclassification of the capital stock of the corporation, or consolidation or merger of the corporation with another corporation, or the sale of all or substantially all of its assets to another corporation shall be effected in such a way that holders of Common Stock shall be entitled to receive stock, securities or assets with respect to or in exchange for Common Stock, then, as a condition of such reorganization, reclassification, consolidation, merger or sale, lawful and adequate provision shall be made whereby each holder of $.70 Preferred Stock shall thereafter have the right to purchase and receive upon the basis and upon the terms and conditions specified herein and in lieu of the shares of the Common Stock of the corporation immediately theretofore issuable upon the conversion of such $.70 Preferred Stock, such shares of stock, securities, or assets as may be issued or payable with respect to or in exchange for a number of outstanding shares of such Common Stock equal to the number of shares of such stock immediately theretofore issuable upon the conversion of such $.70 Preferred Stock had such reorganization, reclassification, consolidation, merger or sale not taken place, and in any such case appropriate provision shall be made with respect to the rights and interests of the holders of the $.70 Preferred Stock to the end that the provisions hereof (including without limitation provisions for adjustments of the Conversion Price) shall thereafter be applicable, as nearly as may be, in relation to any shares of stock, securities, or assets thereafter deliverable upon the conversion of the $.70 Preferred Stock. The corporation shall not effect any such consolidation, merger or sale, unless prior to consummation thereof the successor corporation (if other than the corporation) resulting from such consolidation or merger, or the corporation into or for the securities of which the outstanding shares of Common Stock shall be changed or exchanged in connection with such consolidation or merger or the corporation purchasing such assets shall assume by written instrument executed and mailed to each holder of $.70 Preferred Stock at the time outstanding, the obligation to deliver to such holder such shares of stock, securities or assets as, in accordance with the foregoing provisions, such holder may be entitled to. If a purchase, tender or exchange offer is made to and accepted by the holders of more than 50% of the outstanding shares of Common Stock of the corporation, the corporation shall not effect any consolidation, a merger or sale with the person having made such offer, unless prior to the consummation thereof the holders of the $.70 Preferred Stock shall have been given a reasonable opportunity to then elect to receive upon the conversion of the $.70 Preferred Stock either the stock, securities or assets then issuable with respect to the Common Stock of the corporation or the stock, securities or assets, or the equivalent, issued to previous holders of the Common Stock in accordance with such offer. (f) Notice of Adjustment. Upon any adjustment of the Conversion Price, then and in each such case the corporation shall give written notice thereof to each holder of $.70 Preferred Stock at the time outstanding, which notice shall state the Conversion Price resulting from such adjustment, and shall set forth in reasonable detail the method of calculation thereof and the facts upon which such calculation is based. Such notice shall be given by delivering or mailing the same to each such holder at the address of such holder as it appears on the corporation's stock records. (g) Other Notices. In case at any time: (i) the corporation shall declare any such dividend on its Common Stock at a rate in excess of the rate of the last cash dividend theretofore paid; (ii) the corporation shall pay any dividend payable in stock upon its Common Stock or make any distribution (other than regular cash dividends) to the holders of its Common Stock; (iii) the corporation shall offer for subscription pro rata to the holders of its Common Stock any additional shares of stock of any class or other rights; (iv) there shall be any capital reorganization, or reclassification of the capital stock of the corporation, or consolidation or merger of the corporation with, or sale of all or substantially all of its assets to, another corporation; or (v) there shall be a voluntary or involuntary dissolution, liquidation or winding up of the corporation; then, in any one or more of said cases, the corporation shall give written notice to each holder of $.70 Preferred Stock at the time outstanding, of the date on which (A) the books of the corporation shall close or a record shall be taken for such dividend, distribution or subscription rights, or (B) such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation or winding up shall take place, as the case may be. Such notice shall also specify the date as of which the holders of Common Stock of record shall participate in such dividend, distribution or subscription rights, or shall be entitled to exchange their Common Stock for securities or other property deliverable upon such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation or winding up, as the case may be. Such notice shall be given by delivering or mailing the same to each such holder at the address of such holder as it appears on the corporation's stock records, at least 20 days prior to the action in question and not less than 20 days prior to the record date or the date on which the corporation's transfer books are closed in respect thereto. (h) Certain Events. If any event occurs as to which in the opinion of the Board of Directors of the corporation the other provisions of this section 5.4 are not strictly applicable or if strictly applicable would not fairly protect the conversion rights of the holders of the $.70 Preferred Stock in accordance with the essential intent and principles of such provisions, then the Board of Directors shall make an adjustment in the application of such provisions, in accordance with such essential intent and principles, so as to protect such conversion rights as aforesaid. 5.5. Shares to be Fully Paid; Reservation of Shares. The corporation covenants and agrees that all shares which may be issued upon conversion of the $.70 Preferred Stock will, upon issuance, be fully paid and non-assessable and free from all taxes, liens and charges with respect to the issue thereof; and without limiting the generality of the foregoing, the corporation covenants and agrees that it will from time to time take all such action as may be requisite to assure that the par value per share of the Common Stock is at all times equal to or less than the then effective purchase price per share of the Common Stock issuable upon conversion of the $.70 Preferred Stock. The corporation further covenants and agrees that the corporation will at all times have authorized, and reserved for the purpose of issue or transfer upon the conversion of the $.70 Preferred Stock, a sufficient number of shares of its Common Stock to provide for the conversion of the $.70 Preferred Stock. 5.6. Registration, Approval and Listing. If any shares of Common Stock required to be reserved for purposes of conversion of $.70 Preferred Stock hereunder require registration with or approval of any governmental authority under any Federal or State law, or listing on any national securities exchange, before such shares may be issued upon conversion, the corporation will, at its expense, as expeditiously as possible, use its best efforts to cause such shares to be duly registered or approved or listed on the relevant national securities exchange, as the case may be. 5.7. Issue Tax. The issuance of certificates for shares of Common Stock upon the conversion of $.70 Preferred Stock shall be made without charge to the holders of such $.70 Preferred Stock for any issuance tax in respect thereof, provided that the corporation shall not be required to pay any tax which may be payable in respect of any transfer involved in the issuance and delivery of any certificate in a name other than the holder of the $.70 Preferred Stock converted. 5.8. Closing of Books. The corporation will at no time close its transfer books against the transfer of any shares of Common Stock issued or issuable upon the conversion of the $.70 Preferred Stock in any manner which interferes with the timely exercise of the conversion rights of the holders of the $.70 Preferred Stock. 5.9. Conversion Agent. So long as any $.70 Preferred Stock is outstanding, the corporation will at all times maintain an office or agency in Boston, Massachusetts, for the purpose of accepting $.70 Preferred Stock surrendered for conversion and issuing Common Stock upon the conversion of the $.70 Preferred Stock pursuant to section 5.2 hereof. Initially the office or agency hereunder for such purposes shall be the principal office of The First National Bank of Boston. The corporation will give written notice to each holder of the $.70 Preferred Stock at the time outstanding of any change in such office or agency. 6. Voting Rights; Restrictions on Corporate Action. 6.1. General Voting Rights. Except as otherwise provided by law and in addition to the rights provided for in section 6.2 and section 6.3 hereof, the holders of the $.70 Preferred Stock shall be entitled to one-tenth (1/10) of one vote for each share held and shall be entitled to exercise such voting rights voting with the holders of Common Stock, without distinction as to class at any annual or special meeting of stockholders for the election of directors and on any other matter coming before such meeting. 6.2. Special Right to Elect Director. (a) If and whenever (i) if dividends on the $.70 Preferred Stock shall have been in arrears for a period of 12 calendar months (whether or not consecutive), or (ii) the corporation shall have failed to make any redemption of the $.70 Preferred Stock required by section 4.1 hereof when due, and such failure or failures shall have continued for a period of 12 calendar months (whether or not consecutive), the holders of the outstanding $.70 Preferred Stock shall have the special right, voting separately as a single class, to elect one director of the corporation at the next succeeding annual meeting of stockholders and at each succeeding annual meeting of stockholders thereafter until such right shall terminate as hereinafter provided. At each meeting of stockholders at which the holders of the $.70 Preferred Stock shall have such special right, voting separately as a single class, to elect a director, the presence in person or by proxy of the holders of record of one-third of the total number of shares of the $.70 Preferred Stock at the time outstanding shall be necessary and sufficient to constitute a quorum of such class for such election by such stockholders as a class. (b) Each director elected by the holders of the $.70 Preferred Stock voting separately as a single class as provided in subdivision (a) of this section 6.2 shall hold office until the annual meeting of stockholders next succeeding his election and until his successor, if any, is elected by such holders and qualified or until his death, resignation or removal in the manner provided in the by-laws of the corporation. In case the office of any director shall become vacant, such vacancy may be filled for the unexpired portion of the term by the vote of such stockholders given at a special meeting of such stockholders called for the purpose. (c) Whenever Full Cumulative Dividends on the $.70 Preferred Stock for all past Dividend Periods and for the then current Dividend Period shall have been declared and paid, and all redemptions of the $.70 Preferred Stock required by section 4.1 hereof shall have been made, the right of the holders of the $.70 Preferred Stock, voting separately as a single class, to elect a director as provided in subdivision (a) of this section 6.2 shall terminate at the next succeeding annual meeting of stockholders, but subject always to the same provisions for the vesting of such special right, voting separately as a single class, to elect a director in the case of any future such arrearage or failure. 6.3. Restrictions on Corporate Action. Without the consent of the holders of at least a majority of the shares of the $.70 Preferred Stock at the time outstanding, given in writing without a meeting or by vote at a meeting called for the purpose, at which the holders of the $.70 Preferred Stock shall vote separately as a single class, the corporation shall not (a) Authorize or issue any shares of Senior Stock or any shares of stock or any obligations or warrants or rights convertible into or evidencing rights to purchase any Senior Stock; (b) Authorize or issue any shares of Parity Stock or any shares of stock or any obligations or warrants or rights convertible into or evidencing rights to purchase any Parity Stock unless, immediately after giving effect thereto and to any concurrent transactions, Consolidated Net Income. Available for Dividends for the period of the four most recently completed quarterly accounting periods of the corporation shall have equalled at least 150% of Pro Forma Interest and Preferred Dividends; (c) Declare, order, pay, make or set apart any sum or property for any Junior Stock Payment (except to the extent of the aggregate net cash proceeds received by the corporation after the date of initial issue of the $.70 Preferred Stock from the sale of shares of Junior Stock or of warrants, rights or options to acquire any such shares) unless, immediately after giving effect thereto, Consolidated Net Worth shall be at least $8,000,000; (d) Take any action looking towards its liquidation, dissolution or winding up; (e) Consolidate with or merge into any other person, unless (i) the holders of the $.70 Preferred Stock will receive in such consolidation or merger the same number of shares of stock of the corporation resulting from or surviving such consolidation or merger, having the same relative rights and preferences as the $.70 Preferred Stock, and (ii) after giving effect to such consolidation or merger, the corporation resulting from or surviving such consolidation or merger will have no stock authorized or outstanding having any right or preference as to dividends or assets senior to any right or preference of the $.70 Preferred Stock or of the stock issued to the holders of the $.70 Preferred Stock in such consolidation or merger; (f) Sell, lease, abandon or otherwise dispose of all or substantially all of its properties and assets, except that the corporation may, without such consent, sell or otherwise dispose of all or substantially all of its properties and assets to another corporation if as a result of such trans action (i) the holders of the $.70 Preferred Stock will thereupon receive the same number of shares of stock of the corporation purchasing or otherwise acquiring such properties and assets, having the same relative rights and preferences as the $.70 Preferred Stock, and (ii) after giving effect to such transaction, the corporation purchasing or otherwise acquiring such properties and assets will have no stock authorized or outstanding having any right or preference as to dividends or assets senior to any right or preference of the $.70 Preferred Stock or of the stock issued to the holders of the $.70 Preferred Stock in such transaction; (g) Enter into any agreement or understanding which in any way restricts the corporation's right or ability to declare and pay dividends on, or to make any other distribution with respect to, or to redeem, the $.70 Preferred Stock; or (h) Authorize or effect any amendment to its Certificate of Incorporation or by-laws which would adversely affect or be inconsistent with any of the rights or preferences of the $.70 Preferred Stock or otherwise prejudicial to the interests of the holders of the $.70 Preferred Stock. 7. Change in Tax Laws. In the event that the tax laws of the United States of America are amended after April 15, 1978 so as to allow the corporation to elect, for Federal income tax purposes, whether or not to claim a deduction for dividends or other distributions on or on account of the $.70 Preferred Stock, the corporation shall not, without the unanimous consent of the holders of the shares of the $.70 Preferred Stock at the time outstanding, given in writing without a meeting or by vote at a Meeting called for the purpose, at which the holders of the $.70 Preferred Stock snail vote separately as a single class, elect to claim any such deduction if as a result of such election (a) the deduction for dividends received provided for in Section 243 of the Internal Revenue Code as in effect on April 15, 1978 with respect to dividends on the $.70 Preferred Stock received by any holder thereof would be eliminated or reduced, or (b) the interests of the holders of the $.70 Preferred Stock would otherwise be adversely affected. 8.

After dividends on all shares of Preferred Stock (including cumulative dividends if and to the extent any such shares shall be entitled thereto) shall have been declared and paid or set apart for payment with respect to any quarterly dividend period, then and not otherwise so long as any shares of the Preferred Stock shall remain outstanding, dividends may be declared and paid or set apart for payment with respect to the same quarterly dividend period on the Common Stock out of the assets or funds of the corporation legally available therefor.
