If, upon any such liquidation, dissolution or winding up of the Corporation, the assets distributable among the holders of all Series A Preferred Stock shall be insufficient to permit the payment in full to such holders of the amount per share hereinabove provided, then the entire assets of the Corporation shall be applied ratably to the payment of such amount to the holders of Series A Preferred Stock then outstanding. Neither the merger or the consolidation of the Corporation, nor the sale, lease or conveyance of all or a part of its property and business as an entirety or substantially as an entirety, shall be deemed to be a liquidation, dissolution or winding up of the Corporation within 2 15 the meaning of this paragraph 1(a), unless such sale, lease or conveyance shall be in connection with a plan of liquidation, dissolution or winding up of the Corporation. (b) The Corporation shall give the holders of Series A Preferred Stock at least thirty (30) days prior notice of liquidation, dissolution or winding up of the Corporation. 2. Redemption. The Corporation shall not have a right of redemption with respect to the Series A Preferred Stock. 3. Conversion. (a) The holder of any share or shares of Series A Preferred Stock shall have the right, at its option, to convert all or any portion of such shares into fully paid and nonassessable shares of Common Stock of the Corporation, at any time and from time to time after the date of issuance, at the rate of 50.0 shares of Common Stock for each share of Series A Preferred Stock, or at the rate which results from the making of any adjustment specified in subparagraph (g) hereof (the number of shares of Common Stock issuable at any time, giving effect to the latest prior adjustment pursuant to subparagraph (g) hereof, if any, in exchange for one share of Series A Preferred Stock being hereinafter called the "Conversion Rate"). (b) In order to convert shares of Series A Preferred Stock into shares of Common Stock pursuant to the right of conversion set forth in subparagraph (a) above, the holder thereof shall surrender the certificate or certificates representing such shares of Series A Preferred Stock, duly endorsed to the Corporation or in blank, at the principal office of the Corporation and shall give written notice to the Corporation that such holder elects to convert the same, stating in such notice the name or names in which such holder wishes the certificate or certificates representing shares of Common Stock to be issued. The Corporation shall, within 3 16 five (5) business days, deliver at said office or other place to such holder of Series A Preferred Stock, or to such holder's nominee or nominees, a certificate or certificates for the number of shares of Common Stock to which such holder shall be entitled as aforesaid, together with any cash to which such holder shall be entitled in lieu of fractional shares in an amount equal to the same fraction of the Liquidation Preference on the business day preceding the day of conversion. Shares of Series A Preferred Stock shall be deemed to have been converted as of the date of the surrender of such shares for conversion as provided above, and the person or persons entitled to receive the shares of Common Stock issuable upon such conversion shall be treated for all purposes as the record holder or holders of such shares of Common Stock on such date. Upon conversion of only a portion of the number of shares covered by a certificate representing shares of Series A Preferred Stock surrendered for conversion, the Corporation shall issue and deliver to, or upon the written order of, the holder of the certificate so surrendered for conversion, at the expense of the Corporation, a new certificate covering the number of shares of Series A Preferred Stock representing the unconverted portion of the certificate so surrendered, which new certificate shall entitle the holder thereof to the rights of the shares of Series A Preferred Stock represented thereby to the same extent as if the certificate theretofore covering such unconverted shares had not been surrendered for conversion. (c) Notwithstanding the provisions of subparagraph (a) hereof, the issued and outstanding shares of Series A Preferred Stock shall be automatically converted into fully paid and nonassessable shares of Common Stock at the Conversion Rate immediately upon the earlier of (i) the consummation of the Corporation's initial public offering of Common Stock by a recognized and experienced underwriter pursuant to a registration statement filed with, and 4 17 declared effective by, the Securities and Exchange Commission pursuant to the Securities Act of 1933, as amended, which results in the Common Stock of the Corporation being listed on a national securities exchange or The Nasdaq Stock Market or (ii) 5:00 p.m. Newark, New Jersey time on September 15, 2005 (d) Notwithstanding the provisions of subparagraph (a) hereof, upon the occurrence and during the continuance of an Event of Default, as defined in either promissory note A or promissory note B, both dated as of September __, 2000, issued by MAS, the Corporation, at its option, in connection with the exercise of its rights under the security agreement, dated as of September __, 2000, between MAS and the Corporation, may effect the conversion of the issued and outstanding shares of Series A Preferred Stock into fully paid and nonassessable shares of Common Stock at the Conversion Rate; (e) (i) At least ten (10) days prior to the earlier of an anticipated closing of a sale of Common Stock which meets the requirements of paragraph 3(c)(i), or 5:00 p.m. Newark, New Jersey time on September 15, 2000, and (ii) at least five (5) days prior to conversion effected by the Corporation pursuant to subparagraph (d), the Corporation shall give written notice to each holder of record of shares of Series A Preferred Stock, by certified mail enclosed in a postage paid envelope addressed to such holder at such holder's address as the same shall appear on the books of the Corporation. Such notice shall (i) state that such shares are being converted pursuant to paragraphs 3(c) or (d) hereof, (ii) state the date of conversion and (iii) call upon such holder to exchange on or after such date at the principal place of business of the Corporation a certificate or certificates representing the number of shares of Series A Preferred Stock to be converted in accordance with such notice. On or after such date, the holder of Series 5 18 A Preferred Stock shall present and surrender the certificate or certificates for the shares of Series A Preferred Stock to the Corporation at the place designated in such notice, and thereupon the Corporation shall deliver to such holder, or to such holder's nominee or nominees, a certificate or certificates for the number of shares of Common Stock to which such holder shall be entitled as aforesaid. Shares of Series A Preferred Stock shall be deemed to have been converted and cancelled on such conversion date and the person or persons entitled to receive the shares of Common Stock issuable upon such automatic conversion shall be treated for all purposes as the record holder or holders of such shares of Common Stock on such conversion date. In the case of automatic conversion pursuant to paragraph 3(c) or (d) hereof, the Corporation shall not be obligated to issue certificates for shares of Common Stock unless certificates evidencing the converted shares of Series A Preferred Stock are delivered to the Corporation. (f) The issuance of certificates for shares of Common Stock upon the conversion of shares of Series A Preferred Stock shall be made without charge to the converting stockholder for any original issue or transfer tax in respect of the issuance of such certificates and any such tax shall be paid by the Corporation. (g) The Conversion Rate shall be subject to the following adjustments: (i) If the Corporation shall declare and pay to the holders of Common Stock a dividend or other distribution payable in shares of Common Stock, the Conversion Rate in effect immediately prior thereto shall be adjusted so that the holders of Series A Preferred Stock thereafter surrendered for conversion shall be entitled to receive the number of shares of Common Stock which such holders would have owned or been entitled to receive after the declaration and payment of such dividend or other distribution if such shares of Series A 6 19 Preferred Stock had been converted immediately prior to the record date for the determination of stockholders entitled to receive such dividend or other distribution. (ii) If the Corporation shall subdivide the outstanding shares of Common Stock into a greater number of shares of Common Stock, or combine the outstanding shares of Common Stock into a lesser number of shares, or issue by reclassification of its shares of Common Stock any shares of the Corporation, the Conversion Rate in effect immediately prior thereto shall be adjusted so that the holders of Series A Preferred Stock thereafter surrendered for conversion shall be entitled to receive the number of shares of Common Stock which such holders would have owned or been entitled to receive after the happening of any of the events described above if such shares of Series A Preferred Stock had been converted immediately prior to the happening of such event on the day upon which such subdivision, combination or reclassification, as the case may be, becomes effective. 4. Right of First Refusal. (a) If the Corporation offers to sell Additional Shares of Capital Stock (as defined in paragraph 8) to a third party, the holders of the shares of Series A Preferred Stock, in accordance with paragraph 4(b), shall have a right of first refusal to purchase the Additional Shares of Capital Stock for the same dollar value of Consideration (as defined below) and on the same terms as such third party; provided that the right of first refusal shall not be applicable to a public offering of the Corporation's Capital Stock. The Consideration shall be deemed to be the per share amount of cash and the value of any form of non-cash consideration to be received by the Corporation for the sale of Additional Shares of Capital Stock to such third party. The value of non-cash consideration shall be determined by the Corporation's board of directors, provided 7 20 that if such value is disputed and/or challenged by holders of the shares of Series A Preferred Stock and the Corporation cannot reach a mutually acceptable agreement within 10 business days, all disputes and challenges shall be settled through arbitration to be commenced in the City of Newark under the auspices of the American Arbitration Association. (b) In the event of an offer contemplated by paragraph 4(a), the Corporation shall provide written notice to the holders of the Series A Preferred Stock, setting forth the Consideration and other material terms and conditions of the offer. Such holders shall have ten business days from the date of receipt of any such notice (the "Exercise Period") to agree to purchase in such proportion as they may agree, or failing such agreement, in proportion to the respective numbers of shares of Series A Preferred Stock held by them, the number of Additional Shares of Capital Stock covered by the offer for the same Consideration and otherwise on the same terms and conditions and at the same time specified in the offer; provided that such holders must agree to purchase all of such Additional Shares of Capital Stock and, if they do not so agree during the Exercise Period, the Corporation may sell such Additional Shares of Capital Stock in accordance with such offer. 5. Right to Purchase Additional Shares. (a) If the Corporation shall issue any warrants or stock options or other rights to purchase shares of Common Stock (such warrants, stock options or other rights being hereinafter called "Rights") entitling the holders thereof to purchase shares of Common Stock, the holders of the shares of Series A Preferred Stock, in accordance with paragraph 5(b), shall also have the right to purchase shares of Common Stock for the same dollar value of Consideration (as defined below), and otherwise on the same terms as set forth in the Rights. 8 21 The Consideration shall be deemed to be the per share amount of cash and the value of any form of non-cash consideration to be received by the Corporation upon exercise of the Rights, plus in the case of Rights issued for cash or non-cash consideration the amount thereof attributable to each share of Common Stock subject to the Rights. The value of non-cash consideration shall be conclusively determined by the Corporation's board of directors, provided that if such value is disputed and/or challenged by holders of the Series A Preferred Stock and the Corporation cannot reach a mutually acceptable agreement within 10 business days, all disputes and challenges shall be settled through arbitration to be commenced in the City of Newark under the auspices of the American Arbitration Association. (b) The Corporation shall notify the holders of the Series A Preferred Stock of the issuance of Rights and the terms thereof promptly after such issuance. In the event that at least 1,000 shares of Common Stock are issued at any time or from time to time pursuant to the exercise of Rights, the Corporation shall provide written notice thereof to the holders of the Series A Preferred Stock identifying such Rights in reasonable detail. Such holders shall have ten business days from the date of receipt of any such notice (the "Exercise Period") to purchase, in such proportion as they may agree, or, failing such agreement in proportion to the respective numbers of shares of Series A Preferred Stock held by them, the number of shares of Common Stock (the "Percentage Maintenance Shares") that, when added to the aggregate number of shares of Common Stock issued or issuable upon conversion of the Series A Preferred Stock (the "Aggregate Shares"), would constitute the same percentage of the outstanding Common Stock (assuming conversion of all the then outstanding Series A Preferred Stock) immediately after the purchase of the Percentage Maintenance Shares, as the Aggregate Shares constituted of the 9 22 outstanding Common Stock (assuming conversion of all the then outstanding Series A Preferred Stock) immediately before the issuance of such shares of Common Stock pursuant to the exercise of such Rights. 6. Voting Rights. (a) For so long as the Minimum Number (as defined below) of shares of Series A Preferred Stock designated herein are issued and outstanding, the holders of the Series A Preferred Stock shall have the right, voting separately as a class, to elect a majority of the Board of Directors of the Corporation, with the holders of the Common Stock having the right, voting separately as a class, to elect the remaining directors (the "Common Stock Directors"), provided, however, that at all times during such period, the minimum number of Common Stock Directors shall be fixed at three. The term "Minimum Number" means the number that is 50% of 210,006 as such latter number may be adjusted pursuant to Section 1.03 of the Stock Purchase Agreement. (b) For so long as the Minimum Number of shares of Series A Preferred Stock designated herein are issued and outstanding, any decision by the Board of Directors of the Corporation with respect to the merger, sale of substantially all the assets, or liquidation of the Corporation, a disposition (through licensing out of the ordinary course of business or otherwise) of the Corporation's intellectual property, any decrease in executive compensation, any affiliate transaction, the declaration of dividends or distributions or any amendment to the Corporation's Certificate of Incorporation or by-laws shall require the favorable vote of one of the Common Stock Directors, at the time in office. 10 23 (c) For matters other than as set forth in paragraphs 6(a) and 6(b) and except as otherwise required by the Delaware General Corporation Law, the holders of shares of Series A Preferred Stock shall have the right to vote, together with the holders of all the outstanding shares of Common Stock and not by classes, on all matters on which holders of Common Stock shall have the right to vote. The holders of shares of Series A Preferred Stock shall have the right to cast one vote for each share of Common Stock into which each share of Series A Preferred Stock held by them is at the time convertible. (d) Without the prior approval of the holders of a majority of the shares of Series A Preferred Stock outstanding, the Corporation will not (i) authorize, create or issue any series or shares of capital stock senior or pari passu to the Series A Preferred Stock, or (ii) take any action which would alter or adversely affect the rights of the holders of the Series A Preferred Stock. 7. General Provisions. (a) 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 such shares shall be considered an issue or sale of Common Stock, for the purposes of paragraphs 4 and 5. (b) The Corporation shall at all times reserve and keep available out of its authorized but unissued shares of Common Stock, solely for the purpose of effecting the conversion of Series A Preferred Stock, the full number of shares of Common Stock then deliverable upon the conversion of all shares of Series A Preferred Stock at the time outstanding. The Corporation shall take such corporate action as shall be necessary in order that the 11 24 Corporation may validly and legally issue fully paid and nonassessable shares of Common Stock upon the conversion of Series A Preferred Stock in accordance with the provisions hereof. (c) No fractional shares of Common Stock or scrip representing fractional shares of Common Stock shall be issued upon any conversion of Series A Preferred Stock, but, in lieu thereof, there shall be paid an amount in cash equal to the same fraction of the Liquidation Preference on the business day preceding the day of conversion. (d) Except as otherwise provided herein, the holders of the shares of Series A Preferred Stock have the right to participate in all matters on a share-by-share basis with outstanding shares of Common Stock without regard to class of stock. 8. Definitions. (a) "Additional Shares of Capital Stock" shall mean all shares of stock of the Corporation issued by the Corporation after the date hereof, except Common Stock which may be issued pursuant to (i) conversion of the Series A Preferred Stock and (ii) shares of stock issued pursuant to the exercise of Rights.
