PREFERRED STOCK Except as otherwise provided in this Part B or as otherwise provided by applicable law, all Shares of Class A Preferred and Class B Preferred (each share of Preferred Stock being referred to herein as a "SHARE") shall be identical in all respects and shall entitle the holders thereof to the same rights and privileges, subject to the same modifications, limitations and restrictions. SECTION 1. DIVIDENDS. When and as declared by the Corporation's board of directors and to the extent permitted under the General Corporation Law of Delaware, the Corporation shall pay preferential dividends to the holders of the Preferred Stock as provided in this Section 1. 1A. ACCUMULATING DIVIDENDS. Except as otherwise provided herein: (i) dividends on each Share of the Class A Preferred shall accrue on a daily basis at the rate of 8.75% per annum of the sum of the Liquidation Value thereof plus all accumulated (as provided in Section 1C of this Part B) and unpaid dividends thereon from and including the date of issuance of such Share to and including the date on which the Liquidation Value of such Share (plus all accrued and unpaid dividends thereon) is paid; and (ii) dividends on each Share of the Class B Preferred shall accrue on a daily basis at the rate of 10% per annum of the sum of the Liquidation Value thereof plus all accumulated (as provided in Section 1C of this Part B) and unpaid dividends thereon from and including the date of issuance of such Share to and including the date on which the Liquidation Value of such Share (plus all accrued and unpaid dividends thereon) is paid. Such dividends on each Share of Class A Preferred and Class B Preferred ("ACCUMULATING DIVIDENDS") shall accrue whether or not they have been declared and whether or not there are profits, surplus or other funds of the Corporation legally available for the payment of dividends. The date on which the Corporation initially issues any Share shall be deemed to be its "date of issuance" regardless of the number of times transfer of such Share is made on the stock records maintained by or for the Corporation and regardless of the number of certificates which may be issued to evidence such Share. 1B. NON-ACCUMULATING DIVIDENDS. Except as otherwise provided herein, additional dividends ("NON-ACCUMULATING DIVIDENDS") on each Share of the Class A Preferred shall accrue on a daily basis at the rate of 10% per annum of the sum of the Liquidation Value thereof plus any accumulated (as provided in Section 1C of this Part B) and unpaid Accumulating Dividends thereon from and including the date of issuance of such Share to and including the date on which the Liquidation Value of such Share (plus all accrued and unpaid dividends thereon) is paid.

No Accumulating Dividend shall be deemed to be an "accumulated dividend" under this Part B except as expressly provided in this Section 1C. 1D. DISTRIBUTION OF PARTIAL DIVIDEND PAYMENTS. If at any time the Corporation pays less than the total amount of Accumulating Dividends then accrued with respect to the Preferred Stock, (i) such payment shall first be distributed ratably among the holders of Class A Preferred based upon the aggregate accrued but unpaid Accumulating Dividends on the Shares of Class A Preferred held by each such holder and (ii) any remaining amount shall be distributed ratably among the holders of Class B Preferred based upon the aggregate accrued but unpaid Accumulating Dividends on the Shares of Class B Preferred held by each such holder. 1E. PARTICIPATION IN COMMON STOCK CASH DIVIDEND PAYMENTS. Subject to Section 3 of this Part B, if the Corporation declares or pays any cash dividends on its Common Stock, the Corporation shall also declare and pay to each holder of Class A Preferred, at the same time that it declares and pays such cash dividends on its Common Stock, the dividends which would have been declared and paid with respect to the Common Stock issuable upon conversion of each Share of Class A Preferred then held by such holder had such Shares of Class A Preferred been converted immediately prior to the record date for such dividend, or if no record date is fixed, the date as of which the record holders of Common Stock entitled to such dividends are to be determined. SECTION 2. LIQUIDATION. Upon any liquidation, dissolution or winding up of the Corporation, (a) each holder of Class A Preferred shall be entitled to be paid, before any distribution or payment is made upon any Junior Securities, an amount in cash equal to the greater of (i) the aggregate Liquidation Value (plus all accrued and unpaid Accumulating Dividends and Non-Accumulating Dividends) of all Shares held by such holder and (ii) the amount that would have been paid to such holder with respect to the Class A Common issuable upon conversion of the Class A Preferred had all of the Class A Preferred been converted immediately prior to such liquidation, dissolution or winding up, and (b) each holder of Class B Preferred shall be entitled to be paid, before any distribution or payment is made upon any Junior Securities, an amount in cash equal to the aggregate Liquidation Value (plus all accrued and unpaid Accumulating Dividends) of all Shares held by such holder, and thereafter the holders of Preferred Stock shall not be entitled to any further payment. If upon any such liquidation, dissolution or winding up of the Corporation, -12- the Corporation's assets to be distributed among the holders of Preferred Stock are insufficient to permit payment to such holders of the aggregate amount which they are entitled to be paid, then the entire assets to be distributed shall first be distributed ratably among the holders of Class A Preferred based upon the aggregate Liquidation Value (plus all accrued and unpaid Accumulating Dividends and Non-Accumulating Dividends thereon) of the Class A Preferred held by each such holder and any remaining assets shall be distributed ratably among the holders of Class B Preferred based upon the aggregate Liquidation Value (plus all accrued and unpaid Accumulating Dividends thereon) of the Class B Preferred held by each such holder. Prior to the time of any liquidation, dissolution or winding up of the Corporation, the Corporation shall declare for payment all accrued and unpaid Accumulating Dividends and Non-Accumulating Dividends with respect to the Preferred Stock. The Corporation shall mail written notice of such liquidation, dissolution or winding up, not less than 60 days prior to the payment date stated therein, to each record holder of Preferred Stock (which notice shall reaffirm the right of each holder of Shares of Class A Preferred to convert such holder's Shares into Class A Common in accordance with Section 7 of this Part B). Neither the consolidation or merger of the Corporation into or with any other entity or entities, nor the sale or transfer by the Corporation of all or any part of its assets, nor the reduction of the capital stock of the Corporation, shall be deemed to be a liquidation, dissolution or winding up of the Corporation within the meaning of this Section 2. SECTION 3. PRIORITY OF PREFERRED STOCK. So long as any Preferred Stock remains outstanding, neither the Corporation nor any Subsidiary shall redeem, purchase or otherwise acquire directly or indirectly any Junior Securities, nor shall the Corporation directly or indirectly pay or declare any dividend or make any distribution upon any Junior Securities, if at the time of or immediately after any such redemption, purchase, acquisition, dividend or distribution the Corporation has failed to pay the full amount of Accumulating Dividends accrued on the Preferred Stock or the Corporation has failed to make any redemption of the Preferred Stock required hereunder; PROVIDED that the Corporation may purchase (i) Junior Securities from present or former employees, officers or directors of or consultants to the Corporation and its Subsidiaries, (ii) Junior Securities pursuant to the Stockholders Agreement between the Corporation and Cardinal Packaging, Inc. Employee Stock Ownership Plan (or any successor plan), dated as of January __, 1996, as the same may be amended or replaced, and (iii) pursuant to any right of refusal arising out of or relating to the Cardinal Packaging, Inc. Employee Stock Ownership Plan (or any successor plan) or applicable law. SECTION 4. REDEMPTIONS. 4A. SCHEDULED REDEMPTIONS. (i) On June 30, 2003 (the "CLASS A SCHEDULED REDEMPTION DATE"), the Corporation shall redeem all outstanding Shares of Class A Preferred at a price per Share equal to the Liquidation Value thereof (plus accrued and unpaid Accumulating Dividends and Non-Accumulating Dividends thereon). Notwithstanding the foregoing, if at any time after delivery of the notice required pursuant to Section 4D but prior to the Class A Scheduled Redemption Date, the holders of a majority of the outstanding Shares of Class -13- A Preferred deliver written notice to the Corporation requesting a deferral of such redemption, then the redemption of Class A Preferred shall be deferred (and the Shares of Class A Preferred shall remain outstanding and shall continue to retain all rights and preferences set forth herein) until the later of (a) the date on which the holders of a majority of the outstanding Shares of Class A Preferred deliver written notice to the Corporation terminating the request for deferral (the "CLASS A DEFERRAL TERMINATION NOTICE") and (b) the date on which such Shares of Class A Preferred are otherwise actually redeemed or purchased by the Corporation. The Corporation shall be obligated to redeem all such Shares of Class A Preferred within 30 days after receipt of the Class A Deferral Termination Notice. (ii) On June 30, 2003 (the "CLASS B SCHEDULED REDEMPTION DATE"), the Corporation shall redeem all outstanding Shares of Class B Preferred at a price per Share equal to the Liquidation Value thereof (plus accrued and unpaid Accumulating Dividends thereon). Notwithstanding the foregoing, if at any time after delivery of the notice required pursuant to Section 4D but prior to the Class B Scheduled Redemption Date, the holders of a majority of the outstanding Shares of Class B Preferred deliver written notice to the Corporation requesting a deferral of such redemption, then the redemption of Class B Preferred shall be deferred (and the Shares of Class B Preferred shall remain outstanding and shall continue to retain all rights and preferences set forth herein) until the later of (a) the date on which the holders of a majority of the outstanding Shares of Class B Preferred deliver written notice to the Corporation terminating the request for deferral (the "CLASS B DEFERRAL TERMINATION NOTICE") and (b) the date on which such Shares of Class B Preferred are otherwise actually redeemed or purchased by the Corporation. Subject to the immediately following sentence, the Corporation shall be obligated to redeem all such Shares of Class B Preferred within 30 days after receipt of the Class B Deferral Termination Notice. 4B. OPTIONAL REDEMPTIONS. (i) The Corporation may at any time and from time to time following the occurrence of a Significant Corporate Transaction (as defined below) redeem any portion of the Shares of Preferred Stock then outstanding at a price per Share equal to the Liquidation Value thereof (plus all accrued and unpaid Accumulating Dividends and Non-Accumulating Dividends thereon). For purposes of this Section 4B, a "Significant Corporate Transaction" shall mean any of the following: (1) any sale or issuance or series of sales and/or issuances of Shares of the Corporation's capital stock by the Corporation or any holders thereof which results in any Person or group of affiliated Persons (other than the owners of Common Stock as of February 1, 1996) owning capital stock of the Corporation possessing the voting power (under ordinary circumstances) to elect a majority of the Corporation's board of directors, (2) any sale or transfer of all or substantially all of the assets of the Corporation and its Subsidiaries on a consolidated basis (measured by fair market value determined in the reasonable good faith judgment of the Corporation's board of directors) in any transaction or series of transactions (other than sales in the ordinary course of business), (3) any merger or consolidation to which the Corporation is a party except for a merger in which the Corporation is the surviving corporation and, after giving effect to such merger, the holders of the Corporation's -14- outstanding capital stock possessing a majority of the voting power (under ordinary circumstances) to elect a majority of the Corporation's board of directors immediately prior to the merger shall own the Corporation's outstanding capital stock possessing the voting power (under ordinary circumstances) to elect a majority of the Corporation's board of directors and (4) a public offering of the Corporation's Common Stock registered under the Securities Act of 1933, as amended. If a proposed Significant Corporate Transaction does not occur, all notices for redemption in connection therewith shall be automatically rescinded. (ii) Redemptions made pursuant to this paragraph 4B shall not relieve the Corporation of its obligation to redeem Preferred Stock on the scheduled redemption date pursuant to paragraph 4A hereof. 4C. REDEMPTION PAYMENT. For each Share which is to be redeemed, the Corporation shall be obligated on the Redemption Date to pay to the holder thereof (upon surrender by such holder at the Corporation's principal office of the certificate representing such Share) an amount equal to the Liquidation Value of such Share (plus all accrued and unpaid Accumulating Dividends and Non-Accumulating Dividends thereon). If, upon a scheduled redemption date on which both classes of Preferred Stock are required to be redeemed (I.E., the holders of one class of Preferred Stock have not delivered a deferral notice as set forth in Section 4A), the funds of the Corporation legally available for redemption of Shares are insufficient to permit redemption of both the Class A Preferred and the Class B Preferred, then those funds that are available shall first be used to redeem the maximum possible number of Shares ratably among the holders of Class A Preferred based upon the aggregate Liquidation Value (plus all accrued and unpaid Accumulating Dividends and Non-Accumulating Dividends thereon) of the Class A Preferred held by each holder of Class A Preferred, and any remaining funds that are available shall be used to redeem the maximum possible number of Shares ratably among the holders of Class B Preferred based upon the aggregate Liquidation Value (plus all accrued and unpaid Accumulating Dividends thereon) of the Class B Preferred held by each holder of Class B Preferred. At any time thereafter when additional funds of the Corporation are legally available for the redemption of Shares, such funds shall immediately be used to redeem the balance of the Shares which the Corporation has become obligated to redeem on any Redemption Date (in accordance with the terms hereof) but which it has not redeemed. 4D. NOTICE OF REDEMPTION. The Corporation shall deliver written notice of each redemption of Preferred Stock to each record holder not less than 60 days prior to the date on which such redemption is to be made (which notice shall, if applicable, reaffirm the right of each holder of Shares of Class A Preferred to convert such holder's Shares into Class A Common in accordance with Section 7 of this Part B). Upon the giving of any such notice of redemption which relates to a redemption at the Corporation's option, the Corporation shall become obligated to redeem the total number of Shares specified in such notice at the time of redemption specified therein (less the total number of Shares that may have been converted by the holders thereof into Class A Common in accordance with the terms of this Part B). In case fewer than the total number of Shares -15- represented by any certificate are redeemed, a new certificate representing the number of unredeemed Shares shall be issued to the holder thereof without cost to such holder promptly after surrender of the certificate representing the redeemed Shares. 4E. DIVIDENDS AFTER REDEMPTION DATE. No Shares is entitled to any dividends accruing after the date on which the Liquidation Value of such Share (plus all accrued and unpaid Accumulating Dividends and Non-Accumulating Dividends thereon) is paid to the holder thereof. On such date all rights of the holder of such Share shall cease, and such Share shall not be deemed to be outstanding. 4F. REDEEMED OR OTHERWISE ACQUIRED SHARES. Any Shares which are redeemed or otherwise acquired by the Corporation shall be cancelled and shall not be reissued, sold or transferred. SECTION 5. VOTING RIGHTS. Except as otherwise provided herein and as otherwise required by law, the Preferred Stock shall have no voting rights; PROVIDED that the holders of Class A Preferred shall be entitled to vote with the holders of the Class A Common (voting together as a single class) on all matters submitted to the holders of the Class A Common for a vote, with each share of Class A Common being entitled to one vote per share and each Share of Class A Preferred entitled to one vote for each share of Class A Common issuable upon conversion of the Class A Preferred at the time the vote is taken. SECTION 6. REGISTRATION OF TRANSFER; RESTRICTION ON OWNERSHIP. (i) The Corporation shall keep at its principal office (or such other place as the Corporation reasonably designates) a register for the registration of Preferred Stock. Upon the surrender of any certificate representing Preferred Stock at such place, the Corporation shall, at the request of the record holder of such certificate, execute and deliver (at the Corporation's expense) a new certificate or certificates in exchange therefor representing in the aggregate the number of Shares represented by the surrendered certificate, and the Corporation forthwith shall cancel such surrendered certificate. Each such new certificate will be registered in such name and shall represent such number of Shares as is required by the holder of the surrender certificate and will be substantially identical in form to the surrendered certificate, and dividends shall accrue on the Preferred Stock represented by such new certificate from the date to which dividends have been fully paid on such Preferred Stock represented by the surrendered certificate. The issuance of new certificates shall be made without charge to the holders of the surrendered certificates for any issuance tax in respect thereof or other cost incurred by the Corporation in connection with such issuance. (ii) Ownership of Shares of Class A Preferred shall be restricted to the Corporation or any of its Subsidiaries, any employee of the Corporation or any of its Subsidiaries (but not a former employee) or to an employee stock ownership plan (within -16- the meaning of the Internal Revenue Code of 1986, as amended), and no other persons shall be permitted to own or otherwise hold any Shares of Class A Preferred. SECTION 7. CONVERSION. 7A. CONVERSION OF CLASS A PREFERRED. Each holder of Class A Preferred shall be entitled at any time to convert any or all of the Shares of such holder's Class A Preferred into a number of Shares of Class A Common computed by multiplying the number of Shares to be converted by $100.00 and dividing the result by the Conversion Price then in effect (as defined in Section 7C of this Part B). Promptly following conversion (and in any event within 90 days), all accrued but unpaid Accumulating Dividends and Non-Accumulating Dividends on a converted Share shall be paid to the holder of such Share, and if the funds of the Corporation are legally available for payment of such dividends on the date of payment are insufficient to pay all such dividends on such payment date, those funds which are legally available shall be used to pay such dividends to the holders of the Shares being converted based upon the aggregate Liquidation Value of such Shares (plus all accrued and unpaid Accumulating Dividends and Non-Accumulating Dividends thereon) held by each such holder. Interest on such dividends shall accrue from the date of conversion until final payment of such dividends at the per annum rate paid on three-month U.S. Treasury Bills issued immediately prior to the date of conversion. 7B. CONVERSION PROCEDURE. (i) Conversion of Shares of Class A Preferred into Shares of Class A Common shall be effected by the surrender of the certificate or certificates representing the Shares to be converted at the principal office of the Corporation at any time during normal business hours, together with a written notice by the holder of such Class A Preferred stating that such holder desires to convert the Shares, or a stated number of the Shares, of such Class A Preferred represented by such certificate or certificates into Shares of Class A Common. Each conversion shall be deemed to have been effected as of the close of business on the date on which such certificate or certificates have been surrendered and such notice has been received (or such later date as specified in such notice), and at such time the rights of the holder of the converted Class A Preferred as such holder shall cease and the person or persons in whose name or names the certificate or certificates for Shares of Class A Common are to be issued upon such conversion shall be deemed to have become the holder or holders of record of the Shares of Class A Common represented thereby. (ii) Promptly after the surrender of certificates and the receipt of the written notice or the request described above, the Corporation shall issue and deliver in accordance with the surrendering holder's instructions (a) the certificate or certificates for the Class A Common issuable upon such conversion and (b) a certificate representing any Class A Preferred which was represented by the certificate or certificates delivered to the Corporation in connection with such conversion but which was not converted. -17- (iii) The issuance of certificates for Class A Common upon conversion of Class A Preferred will be made without charge to the holders of such Shares for any issuance tax in respect thereof or other cost incurred by the Corporation in connection with such conversion and the related issuance of Class A Common. (iv) The Corporation shall at all times reserve and keep available out of its authorized but unissued Shares of Class A Common, solely for the purpose of issuance upon the conversion of the Class A Preferred, such number of Shares of Class A Common issuable upon the conversion of all outstanding Class A Preferred. All Shares of Class A Common issuable upon the conversion of the Class A Preferred shall, when issued, be duly and validly issued, fully paid and nonassessable and free from all taxes, liens and charges. The Corporation shall take all such actions as may be necessary to assure that all such Shares of Class A Common may be so issued without violation of any applicable law or governmental regulation or any requirements of any domestic securities exchange upon which Shares of Class A Common may be listed (except for official notice of issuance which will be immediately transmitted by the Corporation upon issuance). (v) The Corporation shall not close its books against the transfer of Shares of Common Stock in any manner which would interfere with the timely conversion of any Shares of Class A Preferred. 7C. CONVERSION PRICE. (i) GENERAL. The initial Conversion Price shall be $94.545. The Conversion Price shall be subject to adjustment from time to time pursuant to this Section 7C. (ii) SUBDIVISION OR COMBINATION OF COMMON STOCK. If the Corporation at any time subdivides (by any stock split, stock dividend, recapitalization or otherwise) one or more classes of 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 if the Corporation at any time combines (by reverse stock split or otherwise) one or more classes of its outstanding Shares of Common Stock into a smaller number of Shares, the Conversion Price in effect immediately prior to such combination shall be proportionately increased. (iii) REORGANIZATION, RECLASSIFICATION, CONSOLIDATION, MERGER OR SALE. Any recapitalization, reorganization, reclassification, consolidation, merger, sale of all or substantially all of the Corporation's assets to another Person or other transaction which is effected in such a manner that holders of Common Stock are entitled to receive (either directly or upon subsequent liquidation) stock, securities or assets with respect to or in exchange for Common Stock is referred to herein as an "Organic Change." Prior to the consummation of any Organic Change, the Corporation shall make appropriate provisions to insure that each of the holders of Class A Preferred shall thereafter have the right to acquire and receive, in lieu of or in addition to (as the case may be) the Shares of Class A Common immediately theretofore acquirable and receivable upon the conversion -18- of such holder's Class A Preferred, such Shares of stock, securities or assets as such holder would have received in connection with such Organic Change if such holder had converted its Class A Preferred immediately prior to such Organic Change. In each such case, the Corporation shall also make appropriate provisions to insure that the provisions of this Section 7 and Section 3 and 4 hereof shall thereafter be applicable to the Preferred Stock (including, in the case of any such consolidation, merger or sale in which the successor entity or purchasing entity is other than the Corporation, an immediate adjustment of the Conversion Price to the value for the Common Stock reflected by the terms of such consolidation, merger or sale, and a corresponding immediate adjustment in the number of Shares of Class A Common acquirable and receivable upon conversion of Class A Preferred, if the value so reflected is less than the Conversion Price in effect immediately prior to such consolidation, merger or sale). (iv) NOTICES. Immediately upon any adjustment of the Conversion Price, the Corporation shall give written notice thereof to all holders of Class A Preferred setting forth in reasonable detail the calculation of such adjustment. SECTION 8. REPLACEMENT. Upon receipt of evidence reasonably satisfactory to the Corporation (an affidavit of the registered holder shall be satisfactory) of the ownership and the loss, theft, destruction or mutilation of any certificate evidencing Shares, and in the case of any such loss, theft or destruction, upon receipt of indemnity reasonably satisfactory to the Corporation (provided that if the holder is a financial institution, other institutional investor or executive officer of the Corporation, such holder's own agreement shall be satisfactory), or, in the case of any such mutilation upon surrender of such certificate, the Corporation shall (at its expense) execute and deliver in lieu of such certificate a new certificate of like kind representing the number of Shares represented by such lost, stolen, destroyed or mutilated certificate and dated the date of such lost, stolen, destroyed or mutilated certificate, and dividends shall accrue on the Preferred Stock represented by such new certificate from the date to which dividends have been fully paid on such lost, stolen, destroyed or mutilated certificate. SECTION 9. DEFINITIONS. "JUNIOR SECURITIES" means any of the Corporation's equity securities other than the Preferred Stock. "LIQUIDATION VALUE" of any Share as of any particular date shall be equal to $100.00.

"REDEMPTION DATE" as to any Share means the date specified in the notice of any redemption at the Corporation's option or the applicable date specified herein in the case of any other redemption; PROVIDED that no such date shall be a Redemption Date unless the Liquidation -19- Value of such Share (plus all accrued and unpaid Accumulating Dividends and Non-Accumulating Dividends thereon) is actually paid in full on such date, and if not so paid in full, the Redemption Date shall be the date on which such amount is fully paid. "SUBSIDIARY" means any corporation of which the Shares of outstanding capital stock possessing the voting power (under ordinary circumstances) in electing the board of directors are, at the time as of which any determination is being made, owned by the Corporation either directly or indirectly through Subsidiaries.

Except as otherwise expressly provided hereunder, all notices referred to herein shall be in writing and shall be delivered by registered or certified mail, return receipt requested and postage prepaid, or by reputable overnight courier service, charges prepaid, and shall be deemed to have been given when so mailed or sent (i) to the Corporation, at its principal executive offices and (ii) to any stockholder, at such holder's address as it appears in the stock records of the Corporation (unless otherwise indicated by any such holder).

SECTION 2. DIVIDENDS. As and when dividends are declared or paid thereon, whether in cash, property or securities of the Corporation, the holders of Class A Common, the holders of Class B Common and the holders of Class C Common shall, subject to the terms of Section 1E of Part B above, be entitled to participate in such dividends ratably on a per share basis; PROVIDED that (i) if dividends are declared which are payable in Shares of Class A Common, Class B Common or Class C Common, dividends shall be declared which are payable at the same rate on all classes of stock, and the dividends payable in Shares of Class A Common shall be payable to holders of that class of stock, the dividends payable in Shares of Class A Common shall be payable to holders of that class of stock, the dividends payable in Shares of Class B Common shall be payable to holders of that class of stock and the dividends payable in Shares of Class C Common shall be payable to holders of that class of stock and (ii) if the dividends consist of other voting securities of the Corporation, the Corporation shall make available to each holder of Class B Common or Class C Common, at such holder's request, dividends consisting of non-voting securities of the Corporation which are otherwise identical to the voting securities and, in the case of the holders of Class B Common or Class C Common, which are convertible into or exchangeable for such voting securities on the same terms as the Class B Common or Class C Common, as applicable, is convertible into the Class A Common. The right of the holders of Common Stock to receive dividends are subject to the provisions of the Preferred Stock in Part B above. SECTION 3. LIQUIDATION. Subject to the provisions of the Preferred Stock in Part B above, the holders of the Class A Common, the Class B Common and the Class C Common shall be entitled to participate ratably on a per share basis in all distributions to the holders of Common Stock in any liquidation, dissolution or winding up of the Corporation. SECTION 4. CONVERSION. 4A. CONVERSION OF CLASS B COMMON. Each holder of Class B Common shall be entitled at any time to convert any or all of the Shares of such holder's Class B Common into the same number of Class A Common or the same number of Class C Common. 4B. CONVERSION OF CLASS C COMMON. Upon the occurrence (or the expected occurrence as described in (iii) below) of any Conversion Event, each holder of Class C Common shall be entitled to convert any or all of -21- the Shares of such holder's Class C Common into the same number of Shares of Class A Common. For purposes of this paragraph 4B, a "Conversion Event" shall mean any public offering or public sale of securities of the Corporation (including a public offering registered under the Securities Act of 1933 and a public sale pursuant to Rule 144 of the Securities and Exchange Commission or any similar rule then in force). Each holder of Class C Common shall be entitled to convert Shares of Class C Common in connection with any Conversion Event if such holder reasonably believes that such Conversion Event will be consummated, and a written request for conversion from any holder of Class C Common to the Corporation stating such holder's reasonable belief that a Conversion Event shall occur shall be conclusive and shall obligate the Corporation to effect such conversion in a timely manner so as to enable each such holder to participate in such Conversion Event. The Corporation will not cancel the Shares of Class C Common so converted before the tenth day following such Conversion Event and will reserve such Shares until such tenth day for reissuance in compliance with the next sentence. If any Shares of Class C Common are converted into Shares of Class A Common in connection with a Conversion Event and such Shares of Class A Common are not actually distributed, disposed of or sold pursuant to such Conversion Event, such Shares of Class A Common shall be promptly converted back into the same number of Shares of Class C Common. 4C. CONVERSION PROCEDURE. (i) Each conversion of Shares of Class B Common or Class C Common into Shares of Class A Common or Class C Common shall be effected by the surrender of the certificate or certificates representing the Shares to be converted at the principal office of the Corporation at any time during normal business hours, together with (a) in the case of Class B Common, a written notice by the holder of such Class B Common stating that such holder desires to convert the Shares, or a stated number of the Shares, of such Class B Common represented by such certificate or certificates into Shares of Class A Common or Class C Common or (b) in the case of Class C Common, the request described in Section 4B(iii) hereof. Each conversion shall be deemed to have been effected as of the close of business on the date on which such certificate or certificates have been surrendered and such notice has been received (or such later date as specified in the request described in Section 4B(iii)), and at such time the rights of the holder of the converted Class B Common or Class C Common as such holder shall cease and the person or persons in whose name or names the certificate or certificates for Shares of Class A Common or Class C Common, as applicable, are to be issued upon such conversion shall be deemed to have become the holder or holders of record of the Shares of Class A Common or Class C Common represented thereby. (ii) Promptly after the surrender of certificates and the receipt of the written notice or the request described above, the Corporation shall issue and deliver in accordance with the surrendering holder's instructions (a) the certificate or certificates for the Class A Common or Class C Common, as the case may be, issuable upon such conversion and (b) a certificate representing any Class B Common or Class C Common -22- which was represented by the certificate or certificates delivered to the Corporation in connection with such conversion but which was not converted. (iii) The issuance of certificates for Class A Common or Class C Common upon conversion of Class B Common or Class C Common will be made without charge to the holders of such Shares for any issuance tax in respect thereof or other costs incurred by the Corporation in connection with such conversion and the related issuance of Class A Common or Class C Common. (iv) The Corporation shall at all times reserve and keep available out of its authorized but unissued Shares of Class A Common, solely for the purpose of issuance upon the conversion of the Class B Common and Class C Common, such number of Shares of Class A Common issuable upon the conversion of all outstanding Class B Common and all outstanding Class C Common. The Corporation shall at all times reserve and keep available out of its authorized but unissued Shares of Class C Common, solely for the purpose of issuance upon the conversion of the Class B Common, such number of Shares of Class C Common issuable upon the conversion of all outstanding Class B Common. All Shares of Class A Common and Class C Common issuable upon the conversion of the Class B Common and Class C Common shall, when issued, be duly and validly issued, fully paid and nonassessable and free from all taxes, liens and charges. The Corporation shall take all such actions as may be necessary to assure that all such Shares of Class A Common and Class C Common may be so issued without violation of any applicable law or governmental regulation or any requirements of any domestic securities exchange upon which Shares of Class A Common or Class C Common may be listed (except for official notice of issuance which will be immediately transmitted by the Corporation upon issuance). (v) The Corporation shall not close its books against the transfer of Shares of Common Stock in any manner which would interfere with the timely conversion of any Shares of Class B Common or Class C Common. SECTION 5. STOCK SPLITS. If the Corporation in any manner subdivides (by any stock split, stock dividend, recapitalization or otherwise) or combines (by reverse stock split or otherwise) the outstanding Shares of one class of Common Stock, the outstanding Shares of the other classes of Common Stock shall be proportionately subdivided or combined in a similar manner. SECTION 6. REGISTRATION OF TRANSFER. The Corporation shall keep at its principal office (or such other place as the Corporation reasonably designates) a register for the registration of Shares of Common Stock. Upon the surrender of any certificate representing Shares of any class of Common Stock at such place, the Corporation shall, at the request of the registered holder of such certificate, execute and deliver a new certificate or certificates in exchange therefor representing in the aggregate the number of Shares of such class represented by the surrendered certificate, and the Corporation forthwith shall cancel such surrendered certificate. Each such new certificate will be registered -23- in such name and will represent such number of Shares of such class as is requested by the holder of the surrendered certificate and will be substantially identical in form to the surrendered certificate. The issuance of new certificates shall be made without charge to the holders of the surrendered certificates for any issuance tax in respect thereof or other cost incurred by the Corporation in connection with such issuance. SECTION 7. REPLACEMENT. Upon receipt of evidence reasonably satisfactory to the Corporation (an affidavit of the registered holder will be satisfactory) of the ownership and the loss, theft, destruction or mutilation of any certificate evidencing one or more Shares of any class of Common Stock, and in the case of any such loss, theft or destruction, upon receipt of indemnity reasonably satisfactory to the Corporation (provided that if the holder is a financial institution, other institutional investor or executive officer of the Corporation, such holder's own agreement will be satisfactory), or, in the case of any such mutilation upon surrender of such certificate, the Corporation shall (at its expense) execute and deliver in lieu of such certificate a new certificate of like kind representing the number of Shares of such class represented by such lost, stolen, destroyed or mutilated certificate and dated the date of such lost, stolen, destroyed or mutilated certificate. SECTION 8. NOTICES. All notices referred to herein shall be in writing, shall be delivered personally or by first class mail, postage prepaid, and shall be deemed to have been given when so delivered or mailed to the Corporation at its principal executive offices and to any stockholder at such holder's address as it appears in the stock records of the Corporation (unless otherwise specified in a written notice to the Corporation by such holder). SECTION 9. AMENDMENT AND WAIVER. No amendment or waiver of any provision of this Section C shall be effective without the prior approval of the holders of a majority of the then outstanding Class A Common and Class B Common (voting as a single class); PROVIDED that the vote of the holders of a majority of any class of Common Stock shall be required if any such amendment would alter or change the powers, preferences or special rights of the Shares of such class so as to affect such class adversely. -24- AMENDED AND RESTATED CERTIFICATE OF INCORPORATION OF CPI HOLDING CORPORATION (Under Sections 242 And 245) The following Amended and Restated Certificate of Incorporation of CPI Holding Corporation, duly adopted pursuant to Section 245 of the General Corporation Law of the State of Delaware, amends, restates and supersedes the existing Certificate of Incorporation, which was originally filed with the Secretary of State of Delaware on April 27, 1995 under the name EPI Acquisition Corporation.
