     4.   Conversion Rights.

          (a) Conversion. The holder of each outstanding Class A Preferred
     shall, subject to the terms and conditions hereinafter set forth, convert

     Stock at the Conversion Price (as defined in Section 4(b)) in effect on the

     pursuant to the following conditions: (i) at any time, at such

     upon the written notice to the Corporation at the election by the holders
     of seventy-five percent (75%) of the outstanding Class A Preferred, voting

     pursuant to an effective registration statement under the Securities Act of
     1933, as amended; provided, that such sale yields gross proceeds of not
     less than Fifteen Million Dollars ($15,000,000) at a price of not less than
     Five Dollars ($5.00) per share and is made pursuant to a firm commitment
     underwriting which is based upon a pre- money valuation of no less than
     Sixty Million Dollars ($60,000,000) (a "Public Offering").

          (b) Conversion Price. Each Class A Preferred shall be convertible at
     an office or agency referred to below into a number of fully paid and
     nonassessable shares of Common Stock (calculated as to each conversion to
     the nearest one-hundredth (1/100th) of a share) as is determined by
     dividing 63/100 Dollars ($0.63) by the Conversion Price in effect on the
     Conversion Date. As of the date this Amended and Restated Certificate of
     Incorporation was filed with the Secretary of State of Delaware, the price
     at which Common Stock shall initially be issuable upon conversion shall be
     63/100 Dollars ($0.63) per share, which price may be adjusted from time to
     time as provided in Section 4(f) (the "Conversion Price").

          (c) Method of Conversion. In order to exercise such conversion
     privilege, the holder of any Class A Preferred to be converted shall
     present and surrender the certificate(s) representing such Class A
     Preferred during usual business hours at any office or agency of the
     Corporation maintained for the transfer of Class A Preferred and shall
     deliver a written notice of its election to convert the Class A Preferred
     represented by such certificate(s), or any portion thereof, specified in
     such notice. Such notice shall also state the name or names (with address)
     in which the certificate or certificates for


                                        8

   9



     Common Stock issuable on such conversion shall be issued. If so required by
     the Corporation, any certificate for Class A Preferred surrendered for
     conversion shall be accompanied by instruments of transfer, in form
     satisfactory to the Corporation, duly executed by the holder of such Class
     A Preferred or such holder's duly authorized representative. Each
     conversion of Class A Preferred shall be deemed to have been effected on
     the date (the "Conversion Date") on which the certificate or certificates
     representing such Class A Preferred shall have been surrendered and any
     required notice and instruments of transfer received as aforesaid. Subject
     to the provisions of Section 4(f)(viii), the person or persons in whose
     name or names any certificate or certificates for Common Stock shall be
     issuable upon such conversion shall be deemed to have become the holder or
     holders of record of such Common Stock immediately prior to the close of
     business on the Conversion Date. Subject to the provisions of Section
     (f)(viii), as promptly as practicable (and in any event within two (2)
     business days) after the presentation and surrender for conversion, as
     herein provided, of any certificate or certificates for Class A Preferred,
     the Corporation shall issue and deliver at such office or agency, to or
     upon the written order of the holder thereof, a certificate or certificates
     for the number of shares of Common Stock issuable upon such conversion. In
     case any certificate or certificates for Class A Preferred shall be
     surrendered for conversion of less than all of the Class A Preferred
     represented thereby, the Corporation shall deliver at such office or
     agency, to or upon the written order of the holder thereof, a certificate
     or certificates for the number of Class A Preferred represented by such
     surrendered certificate or certificates which are not converted. The
     issuance of certificates for Common Stock issuable upon the conversion of
     Class A Preferred, and the issuance of certificates representing Class A
     Preferred which are not converted as described above, shall be at the
     Corporation's expense and without charge to the converting holder for any
     tax imposed on the Corporation in respect of the issue thereof. The
     Corporation shall not, however, be required to pay any tax which may be
     payable with respect to any transfer involved in the issue and delivery of
     any certificate in a name other than that of the holder of the Class A
     Preferred and the Corporation shall not be required to issue or deliver any
     such certificate unless and until the person requesting the issue thereof
     shall have paid to the Corporation the amount of such tax or has
     established to the satisfaction of the Corporation that such tax has been
     paid.

          (d) No Adjustment for Dividends. With respect to any conversion of
     Class A Preferred into Common Stock pursuant to this Section 4, no
     adjustment shall be made for dividends declared but as yet unpaid on the
     Class A Preferred as of any record date prior to the Conversion Date;
     provided, however, that upon the conversion of such Class A Preferred, the
     dividend declared but as yet unpaid on the Class A Preferred shall be
     payable on the Common Stock issued upon such conversion as if such Common
     Stock were outstanding as of the record date for the determination of
     holders entitled to receive said dividend.

          (e) Fractional Shares. If more than one Class A Preferred share shall
     be surrendered for conversion at one time by the same holder, the number of
     full shares of Common Stock issuable upon conversion thereof shall be
     computed on the basis of the aggregate number of Class A Preferred shares
     so surrendered. If any fractional interest in a share of Common Stock would
     be deliverable upon the conversion of any Class A


                                        9

   10



     Preferred, the Corporation shall issue a certificate which shall evidence
     and include such fractional interest in the Common Stock.

               (f) Conversion Price Adjustments. The Conversion Price for the
     Class A Preferred shall be subject to adjustment from time to time as
     follows:

                    (i) Common Stock Issued at Less Than the Conversion Price.
               If the Corporation shall issue or be deemed to have issued any
               Common Stock other than Excluded Shares (as hereinafter defined)
               without consideration or for a consideration per share less than
               the Conversion Price in effect immediately prior to such issuance
               (the "Additional Common Shares"), the Conversion Price in effect
               immediately prior to each such issuance shall be reduced to a
               price determined by multiplying the then current Conversion Price
               by a fraction (A) the numerator of which shall be the sum of (1)
               the number of shares of Common Stock outstanding immediately
               prior to such issuance, plus (2) the number of shares of Common
               Stock that the aggregate consideration received by the Company
               for the total number of Additional Common Shares so issued would
               purchase at such Conversion Price, and (B) the denominator of
               which shall be the number of shares of Common Stock outstanding
               immediately prior to such issuance plus the number of Additional
               Common Shares so issued.

                    For the purposes of any adjustment of the Conversion Price
               pursuant to this Section 4(f)(i), the following provisions shall
               be applicable:

                         (A) Cash. In the case of the issuance of Common Stock
                    for cash, the amount of the consideration received by the
                    Corporation shall be deemed to be the amount of the cash
                    proceeds received by the Corporation for such Common Stock
                    before deducting therefrom any reasonable discounts,
                    commissions, taxes or other expenses allowed, paid or
                    incurred by the Corporation for any underwriting or
                    otherwise in connection with the issuance and sale thereof.

                         (B) Consideration Other Than Cash. In the case of the
                    issuance of Common Stock (other than upon the conversion of
                    shares of capital stock or other securities of the
                    Corporation) for a consideration in whole or in part other
                    than cash, including securities acquired in exchange
                    therefor (other than securities by their terms so
                    exchangeable), the consideration other than cash shall be
                    deemed to be the fair value thereof (as determined in good
                    faith by the Board of Directors of the Corporation, whose
                    determination shall be conclusive to the extent reasonable),
                    irrespective of any accounting treatment; provided, that
                    such fair value as determined by the Board of Directors
                    shall not exceed the aggregate Current Market Price (as
                    defined in Section 4(g)) of the Common Stock being issued as
                    of the date the Board of Directors authorizes the issuance
                    of such Common Stock.

                         (C) Options and Convertible Securities. In the case of
                    the issuance of (i) options, warrants or other rights to
                    purchase or acquire


                                       10

   11



                    Common Stock (whether or not at the time exercisable) other
                    than Excluded Shares, (ii) securities by their terms
                    convertible into or exchangeable for Common Stock (whether
                    or not at the time so convertible or exchangeable), or (iii)
                    options, warrants or rights to purchase such convertible or
                    exchangeable securities (whether or not at the time
                    exercisable):

                                (1) the aggregate maximum number of shares of
                        Common Stock deliverable upon exercise of such options,
                        warrants or other rights to purchase or acquire Common
                        Stock shall be deemed to have been issued at the time
                        such options, warrants or other rights become
                        exercisable and for a consideration equal to the
                        consideration (determined in the manner provided in
                        Sections 4(f)(i)(A) and (B)), if any, received by the
                        Corporation upon the issuance of such options, warrants
                        or other rights plus the minimum purchase price provided
                        in such options, warrants or other rights for the Common
                        Stock covered thereby;

                                (2) the aggregate maximum number of shares of
                        Common Stock deliverable upon conversion of or in
                        exchange for any such convertible or exchangeable
                        securities, or upon the exercise of options, warrants or
                        other rights to purchase or acquire such convertible or
                        exchangeable securities and the subsequent conversion or
                        exchange thereof, shall be deemed to have been issued at
                        the time such securities become convertible or
                        exchangeable or such options, warrants or other rights
                        become exercisable and for a consideration equal to the
                        consideration, if any, received by the Corporation for
                        any such securities and related options, warrants or
                        other rights (excluding any cash received on account of
                        accrued interest or accrued dividends), plus the
                        additional consideration, if any, to be received by the
                        Corporation upon the conversion or exchange of such
                        securities and the exercise of any related options,
                        warrants or other rights (the consideration in each case
                        to be determined in the manner provided in Sections
                        4(f)(i)(A) and (B));

                                (3) on any change in the number of shares of
                        Common Stock deliverable upon exercise of any such
                        options, warrants or other rights which have become
                        exercisable or conversion of or exchange of such
                        convertible or exchangeable securities which have become
                        convertible or exchangeable, or any change in the
                        consideration to be received by the Corporation upon
                        such exercise, conversion or exchange, including, but
                        not limited to, a change resulting from any subdivision,
                        split-up, combination or reclassification thereof, the
                        Conversion Price as then in effect shall forthwith be
                        readjusted to such Conversion Price as would have been
                        obtained had an adjustment been made upon such options,
                        warrants or other rights not exercised becoming
                        exercisable prior


                                       11

   12



                        to such change, or securities not converted or exchanged
                        becoming convertible or exchangeable prior to such
                        change, upon the basis of such change but only if as a
                        result of such adjustment the Conversion Price then in
                        effect is thereby reduced;

                                (4) on the expiration or cancellation of any
                        such options, warrants or other rights, or the
                        termination of the right to convert or exchange such
                        convertible or exchangeable securities, if the
                        Conversion Price shall have been adjusted upon such
                        becoming exercisable, convertible or exchangeable, such
                        Conversion Price shall forthwith be readjusted to such
                        Conversion Price as would have been obtained had an
                        adjustment been made upon such options, warrants or
                        other rights becoming exercisable or securities becoming
                        convertible or exchangeable on the basis of the issuance
                        of only the number of shares of Common Stock actually
                        issued upon the exercise of such options, warrants or
                        other rights, or upon the conversion or exchange of such
                        securities; and

                                (5) if the Conversion Price shall have been
                        adjusted upon such options, warrants or other rights
                        becoming exercisable or such convertible or exchangeable
                        securities becoming convertible or exchangeable, no
                        further adjustment of the Conversion Price shall be made
                        for the actual issuance of Common Stock upon the
                        exercise, conversion or exchange thereof.

          (ii) Excluded Shares. "Excluded Shares" shall mean Common Stock issued
     or reserved for issuance by the Corporation: (i) as a stock dividend
     payable in shares of Common Stock; (ii) upon any subdivision or split-up of
     the outstanding Common Stock; (iii) to employees, consultants, officers and
     directors of the Corporation designated from time to time by the Board of
     Directors pursuant to a stock option plan, but not exceeding 4,000,000
     shares of Common Stock in the aggregate (adjusted for any stock dividend
     payable in shares of Common Stock, upon any subdivision, split-up,
     combination or reclassification of Common Stock, occurring after the date
     hereof) or such higher number of shares of Common Stock as may be
     designated by the vote or written consent of at least seventy-five percent
     (75%) of the holders of Group I Preferred Stock; (iv) pursuant to the terms
     of any acquisition by the Corporation of all or substantially all of the
     operating assets, or more than fifty percent (50%) of the voting capital
     stock or other management interest of any Person in a transaction expressly
     approved in advance by at least seventy-five percent (75%) of the holders
     of Group I Preferred Stock; (v) upon conversion of Class A Preferred, Class
     B Preferred, Class C Preferred, Class D Preferred, Class E Preferred, Class
     F Preferred, Class G Preferred, Blank Check Preferred or any other class of
     convertible preferred stock; (vi) 89,700 shares of Common Stock issuable to
     Michael Gallo upon exercise of a warrant; and (vii) 606,000 shares of
     Common Stock issuable to certain investors upon exercise of a warrant.



                                       12

   13



               (iii) Stock Dividends; Stock Splits, Etc. If the number of shares
          of Common Stock outstanding at any time after the date of issuance of
          the Class A Preferred is increased by a stock dividend payable in
          Common Stock or by a subdivision or split-up of Common Stock, then
          immediately after the record date fixed for the determination of
          holders of Common Stock entitled to receive such stock dividend or the
          effective date of such subdivision or split-up, as the case may be,
          the Conversion Price shall be appropriately adjusted so that the
          holder of any Class A Preferred thereafter converted shall be entitled
          to receive the number of shares of Common Stock of the Corporation
          which such holder would have owned immediately following such action
          had such Class A Preferred been converted immediately prior thereto.

               (iv) Combination of Shares. If the number of shares of Common
          Stock outstanding at any time after the date of issuance of the Class
          A Preferred is decreased by a combination of the outstanding shares of
          Common Stock, then immediately after the effective date of such
          combination, the Conversion Price shall be appropriately increased so
          that the holder of any Class A Preferred thereafter converted shall be
          entitled to receive the number of shares of Common Stock of the
          Corporation which such holder would have owned immediately following
          such action had such Class A Preferred been converted immediately
          prior thereto.

               (v) Reorganizations, Etc. In the case of any capital
          reorganization of the Corporation, any reclassification of Common
          Stock, the consolidation of the Corporation with or the merger of the
          Corporation with or into any other entity (other than a reorganization
          or merger solely for the purpose of the change in the state of
          incorporation of the Corporation) or the sale, lease or other transfer
          of all or substantially all of the assets of the Corporation to any
          other person or entity, each Class A Preferred shall after such
          capital reorganization, reclassification, consolidation, merger, sale,
          lease or other transfer be convertible into the number of shares of
          capital stock or other securities or property to which the Common
          Stock issuable (at the time of such capital reorganization,
          reclassification, consolidation, merger, sale, lease or other
          transfer) upon conversion of such Class A Preferred would have been
          entitled upon such capital reorganization, reclassification,
          consolidation, merger, sale, lease or other transfer; and in any such
          case, if necessary, the provisions set forth herein with respect to
          the rights and interests thereafter of the holders of the Class A
          Preferred shall be appropriately adjusted so as to be applicable, as
          nearly as may reasonably be possible, to any shares of capital stock
          or other securities or property thereafter deliverable on the
          conversion of the Class A Preferred. The subdivision or combination of
          Common Stock issuable upon conversion of Class A Preferred at any time
          outstanding into a greater or lesser number of shares of Common Stock
          (whether with or without par value) shall not be deemed to be a
          reclassification of the Common Stock of the Corporation for the
          purposes of this Section 4(f)(v).

               (vi) Evidences of Indebtedness or Assets. In case the Corporation
          shall declare a distribution payable in securities of other Persons,
          evidences of indebtedness issued by the Corporation or other Persons
          or assets (excluding cash


                                       13

   14



          dividends or dividends payable solely in Common Stock) then, in each
          such case, each holder of Class A Preferred shall be entitled to
          receive a proportionate share of any such distribution as if it had
          converted into the number of shares of Common Stock of the Corporation
          into which its Class A Preferred would have been convertible as of the
          record date fixed for the determination of the holders of Common Stock
          of the Corporation entitled to receive such distribution.

               (vii) Rounding of Calculations; Minimum Adjustment. All
          calculations under this Section 4(f) shall be made to the nearest cent
          or to the nearest one-hundredth (1/100th) of a share, as the case may
          be. Any provision of this Section 4 to the contrary notwithstanding,
          no adjustment in the Conversion Price shall be made if the amount of
          such adjustment would be less than one cent ($0.01), but any such
          amount shall be carried forward and an adjustment with respect thereto
          shall be made at the time of, and together with, any subsequent
          adjustment which, together with such amount and any other amount or
          amounts so carried forward, shall aggregate one cent ($0.01) or more.

               (viii) Timing of Issuance of Additional Common Shares Upon
          Certain Adjustments. In any case in which the provisions of this
          Section 4(f) shall require that an adjustment shall become effective
          immediately after the record date for an event, the Corporation may
          defer until the occurrence of such event the issuing to the holder of
          any Class A Preferred converted after such record date and before the
          occurrence of such event, the additional shares of Common Stock
          issuable upon such conversion by reason of the adjustment required by
          such event over and above the shares of Common Stock issuable upon
          such conversion before giving effect to such adjustment; provided,
          that the Corporation upon request shall deliver to such holder a due
          bill or other appropriate instrument evidencing such holder's right to
          receive such additional shares upon the occurrence of the event
          requiring such adjustment.

               (ix) Applicable Adjustment. In any case in which the provisions
          of this Section 4(f) shall require an adjustment to the Conversion
          Price for the Class A Preferred, the applicable adjustment shall be
          the largest adjustment lowering the Conversion Price resulting from
          the application of any appropriate provision of this Section 4(f) to
          such event.

          (g) Current Market Price. The "Current Market Price" at any date shall
     mean the price per share of Common Stock on such date determined by the
     Board of Directors as provided in this Section 4(g). The Current Market
     Price shall be the average of the daily closing prices per share of Common
     Stock for thirty (30) consecutive business days ending no more than fifteen
     (15) business days before the day in question (as adjusted for any stock
     dividend, split, combination or reclassification that took effect during
     such thirty (30) business day period). The closing price for each day shall
     be the last reported sales price regular way or, in case no such reported
     sales take place on such day, the average of the last reported bid and
     asked prices regular way, in either case on the principal national
     securities exchange on which the Common Stock is listed or admitted to

     of Securities Dealers Automated Quotation ("NASDAQ") System; provided, that
     if the Common Stock is not traded in such manner that the quotations
     referred to above are available for the period required hereunder, the
     Current Market Price per share of Common Stock shall be deemed to be the
     fair value as determined by the Board of Directors (whose determination
     shall be conclusive), irrespective of any accounting treatment; provided,
     that, if within fifteen (15) days of receiving notice of an event under
     Section 4(f) requiring the calculation of the Current Market Price a holder
     of at least ten percent (10%) of the currently outstanding Class A
     Preferred requests the appointment of an independent appraiser, the Board
     of Directors shall, within ten (10) days of such request, appoint as an
     independent appraiser a nationally-known independent public accounting firm
     or investment bank and the Board of Directors shall direct such independent
     appraiser to conduct an appraisal and make a report on the Current Market
     Price of a share of Common Stock within thirty (30) days of its
     appointment. The determination of the Current Market Price by such
     independent appraiser shall be final and binding upon the Corporation and
     the holders of Class A Preferred. The costs of such independent appraiser
     shall be paid by the Corporation. Any independent appraiser so utilized
     shall agree to treat all information supplied by the Corporation in a
     confidential manner.

          (h) Statement Regarding Adjustments. Whenever the Conversion Price is
     adjusted as herein provided:


               (i) the Corporation shall compute the adjusted Conversion Price
          in accordance with this Section 4 and shall prepare a certificate
          signed by the Treasurer of the Corporation setting forth the adjusted
          Conversion Price and the facts requiring such adjustment, and such
          certificate shall forthwith be filed at the office of the transfer
          agent or agents, if any, for the Class A Preferred and at the
          principal office of the Corporation; and

               (ii) a notice stating that the Conversion Price has been adjusted
          and setting forth the adjusted Conversion Price and the facts
          requiring such adjustment shall, as soon as practicable, be mailed to

          appropriate, such notice may be given in advance and may be included
          as part of a notice required to be mailed under the provisions of
          Section 4(j).

          (i) Cancellation. All Class A Preferred which shall have been
     surrendered for conversion as herein provided in this Section 4 shall no
     longer be deemed to be outstanding and all rights with respect to such
     Class A Preferred, including the rights, if any, to receive notices and to
     vote, shall forthwith cease and terminate, except only the right of the
     holders thereof to receive Common Stock or other assets or property in
     exchange therefor.

          (j) Notice to Holders. In the event that:

               (i) the Corporation shall take action to make any distribution or
          dividend to the holders of any class of its capital stock;

               (ii) the Corporation shall take action to offer for subscription
          pro rata to the holders of any class of its capital stock securities
          of any kind;

               (iii) the Corporation shall take action to accomplish any capital
          reorganization, or reclassification of the capital stock of the
          Corporation (other than a subdivision, split-up or combination of its
          Common Stock), or consolidation or merger to which the Corporation is
          a party and for which approval of any stockholders of the Corporation
          is required, or the sale or transfer of all or substantially all of
          the assets of the Corporation; or

               (iv) the Corporation shall take action looking to a voluntary or
          involuntary dissolution, liquidation or winding up of the affairs of
          the Corporation;

     then the Corporation shall (x) in case of any such distribution, dividend
     or offering of subscription rights, at least ten (10) days prior to the
     date or expected date on which the books of the Corporation shall close or
     a record shall be taken for the determination of holders entitled to such
     distribution or subscription rights, and (y) in the case of any such
     reorganization, reclassification, consolidation, merger, sale, transfer,
     dissolution, liquidation or winding up, at least ten (10) days prior to the
     date or expected date when the same shall take place, cause written notice
     thereof to be mailed to each holder of Class A Preferred at such holder's
     address as shown on the books of the Corporation. The notice to be given in
     accordance with this Section 4 (j) shall also specify (x) the date or
     expected date on which the holders of any class of the Corporation's
     capital stock shall be entitled thereto, and (y) the date or expected date
     on which the holders of any class of the Corporation's capital stock shall
     be entitled to exchange their shares for securities or other property
     deliverable upon such reorganization, reclassification, consolidation,
     merger, sale, transfer, dissolution, liquidation or winding up, as the case
     may be.

          (k) Reservation of Shares. The Corporation shall at all times reserve
     and keep available, free from preemptive rights, out of its treasury shares
     or its authorized but unissued Common Stock, for the purpose of effecting
     the conversion of the Class A Preferred, the full number of shares of
     Common Stock then deliverable upon the conversion of all Class A Preferred
     then outstanding.

          (l) Reclassification of Common Stock. For the purposes of this Section
     4, the term "Common Stock" shall mean (a) the class of stock designated as
     the Common Stock of the Corporation on the date this Amended and Restated
     Certificate of Incorporation is filed with the Secretary of State of
     Delaware, or (b) any other class of stock resulting from successive changes
     or reclassifications of such Common Stock consisting solely of changes in
     par value or from no par value to par value, or from par value to no par
     value. If at any time as a result of an adjustment made pursuant to the
     provisions of Section 4(f)(v), the holder of any Class A Preferred
     thereafter surrendered for conversion shall become entitled to receive any
     shares of the Corporation other than shares of Common Stock, and the number
     of such other shares so receivable upon conversion of any Class A Preferred
     shall be subject to adjustment from time to time in a manner and on terms
     as nearly equivalent as practicable to the provisions with respect to the
     Common


                                       16

   17



     Stock contained in Section 4(f)(v), and the other provisions of this
     Section 4 with respect to the Common Stock shall apply on like terms to any
     such other shares.

          (m) Treasury Shares. For the purpose of this Section 4, the sale or
     other disposition of any Common Stock of the Corporation theretofore held
     in its treasury shall be deemed to be an issuance thereof.

          (n) Approvals. If any Common Stock to be reserved for the purpose of
     conversion of Class A Preferred requires registration with or approval of
     any governmental authority under any Federal or state law or of the NASDAQ
     System before such shares may be validly issued or delivered upon
     conversion, the Corporation will in good faith and as expeditiously as
     possible secure such registration or approval, as the case may be. If, and
     so long as, any shares of Common Stock into which the Class A Preferred are
     then convertible are listed on any national securities exchange, the
     Corporation will, if permitted by the rules of such exchange, list and keep
     listed on such exchange, upon official notice of issuance, all of such
     Common Stock issuable upon conversion.


          (o) Valid Issuance. All Common Stock that may be issued upon
     conversion of the Class A Preferred will upon issuance by the Corporation
     be duly and validly issued, fully paid and nonassessable and free from all
     taxes, liens and charges with respect to the issuance thereof, and the
     Corporation shall take no action which will cause a contrary result
     (including, without limitation, any action which would cause the Conversion
     Price to be less than the par value, if any, of the Common Stock).

     provided, that for the purpose of determining the amount of any such
     dividend payable to the holders of Class B Preferred, such holders shall be
     entitled to receive a proportionate amount of such dividends as if all
     issued and outstanding Class B Preferred had been converted into Common
     Stock as of the record date for the determination of holders entitled to
     receive said dividend.

     corporations with or into the Corporation, nor the reorganization of the
     Corporation, shall be deemed a liquidation, dissolution or winding up of
     the affairs of the Corporation within the meaning of this Section 3 if the
     holders of at least fifty-one percent (51%) of the then outstanding
     Convertible Preferred Shares and Class F Preferred together elect to have
     such events not deemed a liquidation of the Corporation by giving written
     notice to the Corporation.

          (c) After the payment in cash to the holders of Class B Preferred of
     the full preferential amount fixed in accordance with the provisions of
     Section 3(a) with respect to the outstanding Class B Preferred, the holders
     of outstanding Class B Preferred as such will have no right or claim to any
     of the remaining assets of the Corporation.

          (d) In the event (i) the holders of the Class B Preferred vote to
     convert their shares of Class B Preferred into shares of Common Stock
     immediately prior to or in connection with an event specified in Section
     3(a) or (ii) any holder of Class B Preferred otherwise converts their
     shares of Class B Preferred into Common Stock in accordance with such
     holder's rights under Section 4, the priorities and preferences set forth
     in Section 3(a) shall be of no further effect and the holders of such
     Common Stock shall share all of the assets of the Corporation available for
     distribution to all holders of Common Stock ratably in proportion to the
     number of shares of Common Stock held by them respectively.

     4.   Conversion Rights.

          (a) Conversion. The holder of each outstanding Class B Preferred
     shall, subject to the terms and conditions hereinafter set forth, convert
     such Class B Preferred into fully paid and nonassessable shares of Common
     Stock at the Conversion Price (as defined in Section 4(b)) in effect on the
     Conversion Date (as defined in Section 4(c)), at the following times and
     pursuant to the following conditions: (i) at any time, at such
     stockholder's option; (ii) automatically and simultaneously upon the
     Closing of a Public Offering; or (iii) upon the written notice to the
     Corporation at the election by the holders


                                       22

   23



     of seventy-five percent (75%) of the outstanding Class B Preferred, voting
     on an As Converted Basis.

          (b) Conversion Price. Each Class B Preferred shall be convertible at
     an office or agency referred to below into a number of fully paid and
     nonassessable shares of Common Stock (calculated as to each conversion to
     the nearest one-hundredth (1/100th) of a share) as is determined by
     dividing One and 25/100 Dollars ($1.25) by the Conversion Price in effect
     on the Conversion Date. As of the date of this Amended and Restated
     Certificate of Incorporation was filed with the Secretary of State of
     Delaware, the price at which Common Stock shall initially be issuable upon
     conversion shall be One and 25/100 Dollars ($1.25) per share, which price
     may be adjusted from time to time as provided in Section 4(f) (the
     "Conversion Price").

          (c) Method of Conversion. In order to exercise such conversion
     privilege, the holder of any Class B Preferred to be converted shall
     present and surrender the certificate(s) representing such Class B
     Preferred during usual business hours at any office or agency of the
     Corporation maintained for the transfer of Class B Preferred and shall
     deliver a written notice of its election to convert the Class B Preferred
     represented by such certificate(s), or any portion thereof, specified in
     such notice. Such notice shall also state the name or names (with address)
     in which the certificate or certificates for Common Stock issuable on such
     conversion shall be issued. If so required by the Corporation, any
     certificate for Class B Preferred surrendered for conversion shall be
     accompanied by instruments of transfer, in form satisfactory to the
     Corporation, duly executed by the holder of such Class B Preferred or such
     holder's duly authorized representative. Each conversion of Class B
     Preferred shall be deemed to have been effected on the date (the
     "Conversion Date") on which the certificate or certificates representing
     such Class B Preferred shall have been surrendered and any required notice
     and instruments of transfer received as aforesaid. Subject to the
     provisions of Section 4(f)(viii), the person or persons in whose name or
     names any certificate or certificates for Common Stock shall be issuable
     upon such conversion shall be deemed to have become the holder or holders
     of record of such Common Stock immediately prior to the close of business
     on the Conversion Date. Subject to the provisions of Section 4(f)(viii), as
     promptly as practicable (and in any event within two (2) business days)
     after the presentation and surrender for conversion, as herein provided, of
     any certificate for Class B Preferred, the Corporation shall issue and
     deliver at such office or agency, to or upon the written order of the
     holder thereof, a certificate or certificates for the number of shares of
     Common Stock issuable upon such conversion. In case any certificate for
     Class B Preferred shall be surrendered for conversion of less than all of
     the Class B Preferred represented thereby, the Corporation shall deliver at
     such office or agency, to or upon the written order of the holder thereof,
     a certificate or certificates for the number of Class B Preferred
     represented by such surrendered certificate which are not converted. The
     issuance of certificates for Common Stock issuable upon the conversion of
     Class B Preferred, and the issuance of certificates representing Class B
     Preferred which are not converted as described above, shall be at the
     Corporation's expense and without charge to the converting holder for any
     tax imposed on the Corporation in respect of the issue thereof. The
     Corporation shall not, however, be required to pay any tax which may be
     payable with respect to any transfer involved in the issue and delivery of
     any certificate in a name other than that of the holder of the Class B
     Preferred and the Corporation shall not


                                       23

   24



     be required to issue or deliver any such certificate unless and until the
     person requesting the issue thereof shall have paid to the Corporation the
     amount of such tax or has established to the satisfaction of the
     Corporation that such tax has been paid.

          (d) No Adjustment for Dividends. With respect to any conversion of
     Class B Preferred into Common Stock pursuant to this Section 4, no
     adjustment shall be made for dividends declared but as yet unpaid on the
     Class B Preferred as of any record date prior to the Conversion Date;
     provided, however, that upon the conversion of such Class B Preferred, the
     dividend declared but as yet unpaid on the Class B Preferred shall be
     payable on the Common Stock issued upon such conversion as if such shares
     of Common Stock were outstanding as of the record date for the
     determination of holders entitled to receive said dividend.

          (e) Fractional Shares. If more than one Class B Preferred share shall
     be surrendered for conversion at one time by the same holder, the number of
     full shares of Common Stock issuable upon conversion thereof shall be
     computed on the basis of the aggregate number of Class B Preferred shares
     so surrendered. If any fractional interest in a share of Common Stock would
     be deliverable upon the conversion of any Class B Preferred, the
     Corporation shall issue a certificate which shall evidence and include such
     fractional interest in the share of Common Stock.

          (f) Conversion Price Adjustments. The Conversion Price for the Class B
     Preferred shall be subject to adjustment from time to time as follows:

               (i) Common Stock Issued at Less Than the Conversion Price. If the
          Corporation shall issue or be deemed to have issued any Common Stock
          other than Excluded Shares (as defined in Article 4, Section C.
          4(f)(ii) of this Amended and Restated Certificate of Incorporation)
          without consideration or for a consideration per share less than the
          Conversion Price in effect immediately prior to such issuance, the
          Conversion Price in effect immediately prior to each such issuance
          shall be reduced to a price determined by multiplying the then current
          Conversion Price by a fraction (A) the numerator of which shall be the
          sum of (1) the number of shares of Common Stock outstanding
          immediately prior to such issuance, plus (2) the number of shares of
          Common Stock that the aggregate consideration received by the Company
          for the total number of Additional Common Shares so issued would
          purchase at such Conversion Price, and (B) the denominator of which
          shall be the number of shares of Common Stock outstanding immediately
          prior to such issuance plus the number of Additional Common Shares so
          issued.

               For the purposes of any adjustment of the Conversion Price
          pursuant to this Section 4(f)(i), the following provisions shall be
          applicable:

                    (A) Cash. In the case of the issuance of Common Stock for
               cash, the amount of the consideration received by the Corporation
               shall be deemed to be the amount of the cash proceeds received by
               the Corporation for such Common Stock before deducting therefrom
               any reasonable discounts, commissions, taxes or other expenses
               allowed, paid or incurred


                                       24

   25



               by the Corporation for any underwriting or otherwise in
               connection with the issuance and sale thereof.

                    (B) Consideration Other Than Cash. In the case of the
               issuance of Common Stock (other than upon the conversion of
               shares of capital stock or other securities of the Corporation)
               for a consideration in whole or in part other than cash,
               including securities acquired in exchange therefor (other than
               securities by their terms so exchangeable), the consideration
               other than cash shall be deemed to be the fair value thereof (as
               determined in good faith by the Board of Directors of the
               Corporation, whose determination shall be conclusive to the
               extent reasonable), irrespective of any accounting treatment;
               provided, that such fair value as determined by the Board of
               Directors shall not exceed the aggregate Current Market Price (as
               defined in Section 4(g)) of the Common Stock being issued as of
               the date the Board of Directors authorizes the issuance of such
               Common Stock.

                    (C) Options and Convertible Securities. In the case of the
               issuance of (i) options, warrants or other rights to purchase or
               acquire Common Stock (whether or not at the time exercisable)
               other than Excluded Shares, (ii) securities by their terms
               convertible into or exchangeable for Common Stock (whether or not
               at the time so convertible or exchangeable) or (iii) options,
               warrants or rights to purchase such convertible or exchangeable
               securities (whether or not at the time exercisable):

                         (1) the aggregate maximum number of shares of Common
                    Stock deliverable upon exercise of such options, warrants or
                    other rights to purchase or acquire Common Stock shall be
                    deemed to have been issued at the time such options,
                    warrants or other rights become exercisable and for a
                    consideration equal to the consideration (determined in the
                    manner provided in Sections 4(f)(i)(A) and (B) above), if
                    any, received by the Corporation upon the issuance of such
                    options, warrants or other rights plus the minimum purchase
                    price provided in such options, warrants or other rights for
                    the Common Stock covered thereby;

                         (2) the aggregate maximum number of shares of Common
                    Stock deliverable upon conversion of or in exchange for any
                    such convertible or exchangeable securities, or upon the
                    exercise of options, warrants or other rights to purchase or
                    acquire such convertible or exchangeable securities and the
                    subsequent conversion or exchange thereof, shall be deemed
                    to have been issued at the time such securities become
                    convertible or exchangeable or such options, warrants or
                    other rights become exercisable and for a consideration
                    equal to the consideration, if any, received by the
                    Corporation for any such securities and related options,
                    warrants or other rights (excluding any cash received on


                                       25

   26



                    account of accrued interest or accrued dividends), plus the
                    additional consideration, if any, to be received by the
                    Corporation upon the conversion or exchange of such
                    securities and the exercise of any related options, warrants
                    or other rights (the consideration in each case to be
                    determined in the manner provided in Sections 4(f)(i)(A) and
                    (B) above);

                         (3) on any change in the number of shares of Common
                    Stock deliverable upon exercise of any such options,
                    warrants or other rights which have become exercisable or
                    conversion of or exchange of such convertible or
                    exchangeable securities which have become convertible or
                    exchangeable, or any change in the consideration to be
                    received by the Corporation upon such exercise, conversion
                    or exchange, including, but not limited to, a change
                    resulting from any subdivision, split-up, combination or
                    reclassification thereof, the Conversion Price as then in
                    effect shall forthwith be readjusted to such Conversion
                    Price as would have been obtained had an adjustment been
                    made upon such options, warrants or other rights not
                    exercised becoming exercisable prior to such change, or
                    securities not converted or exchanged becoming convertible
                    or exchangeable prior to such change, upon the basis of such
                    change but only if as a result of such adjustment the
                    Conversion Price then in effect is thereby reduced;

                         (4) on the expiration or cancellation of any such
                    options, warrants or other rights, or the termination of the
                    right to convert or exchange such convertible or
                    exchangeable securities, if the Conversion Price shall have
                    been adjusted upon such becoming exercisable, convertible or
                    exchangeable, such Conversion Price shall forthwith be
                    readjusted to such Conversion Price as would have been
                    obtained had an adjustment been made upon such options,
                    warrants or other rights becoming exercisable or securities
                    becoming convertible or exchangeable on the basis of the
                    issuance of only the number of shares of Common Stock
                    actually issued upon the exercise of such options, warrants
                    or other rights, or upon the conversion or exchange of such
                    securities; and

                         (5) if the Conversion Price shall have been adjusted
                    upon such options, warrants or other rights becoming
                    exercisable or such convertible or exchangeable securities
                    becoming convertible or exchangeable, no further adjustment
                    of the Conversion Price shall be made for the actual
                    issuance of Common Stock upon the exercise, conversion or
                    exchange thereof.

               (ii) Excluded Shares. "Excluded Shares" has the meaning given to
          it in Article 4, Section C. 4(f)(ii) of this Amended and Restated
          Certificate of Incorporation.



                                       26

   27



               (iii) Stock Dividends; Stock Splits, Etc. If the number of shares
          of Common Stock outstanding at any time after the date of issuance of
          the Class B Preferred is increased by a stock dividend payable in
          Common Stock or by a subdivision or split-up of Common Stock, then
          immediately after the record date fixed for the determination of
          holders of Common Stock entitled to receive such stock dividend or the
          effective date of such subdivision or split-up, as the case may be,
          the Conversion Price shall be appropriately adjusted so that the
          holder of any Class B Preferred thereafter converted shall be entitled
          to receive the number of shares of Common Stock of the Corporation
          which such holder would have owned immediately following such action
          had such Class B Preferred been converted immediately prior thereto.

               (iv) Combination of Shares. If the number of shares of Common
          Stock outstanding at any time after the date of issuance of the Class
          B Preferred is decreased by a combination of the outstanding shares of
          Common Stock, then immediately after the effective date of such
          combination, the Conversion Price shall be appropriately increased so
          that the holder of any Class B Preferred thereafter converted shall be
          entitled to receive the number of shares of Common Stock of the
          Corporation which such holder would have owned immediately following
          such action had such Class B Preferred been converted immediately
          prior thereto.

               (v) Reorganizations, Etc. In the case of any capital
          reorganization of the Corporation, any reclassification of Common
          Stock, the consolidation of the Corporation with or the merger of the
          Corporation with or into any other entity (other than a reorganization
          or merger solely for the purpose of the change in the state of
          incorporation of the Corporation) or the sale, lease or other transfer
          of all or substantially all of the assets of the Corporation to any
          other person or entity, each Class B Preferred shall after such
          capital reorganization, reclassification, consolidation, merger, sale,
          lease or other transfer be convertible into the number of shares of
          capital stock or other securities or property to which the Common
          Stock issuable (at the time of such capital reorganization,
          reclassification, consolidation, merger, sale, lease or other
          transfer) upon conversion of such Class B Preferred would have been
          entitled upon such capital reorganization, reclassification,
          consolidation, merger, sale, lease or other transfer; and in any such
          case, if necessary, the provisions set forth herein with respect to
          the rights and interests thereafter of the holders of the Class B
          Preferred shall be appropriately adjusted so as to be applicable, as
          nearly as may reasonably be possible, to any shares of capital stock
          or other securities or property thereafter deliverable on the
          conversion of the Class B Preferred. The subdivision or combination of
          Common Stock issuable upon conversion of Class B Preferred at any time
          outstanding into a greater or lesser number of shares of Common Stock
          (whether with or without par value) shall not be deemed to be a
          reclassification of the Common Stock of the Corporation for the
          purposes of this Section 4(f)(v).

               (vi) Evidences of Indebtedness or Assets. In case the Corporation
          shall declare a distribution payable in securities of other Persons,
          evidences of indebtedness issued by the Corporation or other Persons
          or assets (excluding cash


                                       27

   28



          dividends or dividends payable solely in Common Stock) then, in each
          such case, each holder of Class B Preferred shall be entitled to
          receive a proportionate share of any such distribution as if it had
          converted into the number of shares of Common Stock of the Corporation
          into which its Class B Preferred would have been convertible as of the
          record date fixed for the determination of the holders of outstanding
          shares of Common Stock of the Corporation entitled to receive such
          distribution.

               (vii) Rounding of Calculations; Minimum Adjustment. All
          calculations under this Section 4(f) shall be made to the nearest cent
          or to the nearest one-hundredth (1/100th) of a share, as the case may
          be. Any provision of this Section 4 to the contrary notwithstanding,
          no adjustment in the Conversion Price shall be made if the amount of
          such adjustment would be less than one cent ($0.01), but any such
          amount shall be carried forward and an adjustment with respect thereto
          shall be made at the time of, and together with, any subsequent
          adjustment which, together with such amount and any other amount or
          amounts so carried forward, shall aggregate one cent ($0.01) or more.

               (viii) Timing of Issuance of Additional Common Shares Upon
          Certain Adjustments. In any case in which the provisions of this
          Section 4(f) shall require that an adjustment shall become effective
          immediately after the record date for an event, the Corporation may
          defer until the occurrence of such event the issuing to the holder of
          any Class B Preferred converted after such record date and before the
          occurrence of such event the Additional Common Shares issuable upon
          such conversion by reason of the adjustment required by such event
          over and above the Common Stock issuable upon such conversion before
          giving effect to such adjustment; provided, that the Corporation upon
          request shall deliver to such holder a due bill or other appropriate
          instrument evidencing such holder's right to receive such additional
          shares upon the occurrence of the event requiring such adjustment.

               (ix) Applicable Adjustment. In any case in which the provisions
          of this Section 4(f) shall require an adjustment to the Conversion
          Price for the Class B Preferred, the applicable adjustment shall be
          the largest adjustment lowering the Conversion Price resulting from
          the application of any appropriate provision of this Section 4(f) to
          such event.

     (g) Current Market Price. "Current Market Price" shall have the meaning
given in Article 4, Section C. 4.(g) of this Amended and Restated Certificate of
Incorporation; provided, that, if within fifteen (15) days of receiving notice
of an event under Section 4(f) requiring the calculation of the Current Market
Price a holder of at least ten percent (10%) of the currently outstanding Class
B Preferred requests the appointment of an independent appraiser, the Board of
Directors shall, within ten (10) days of such request, appoint as an independent
appraiser a nationally-known independent public accounting firm or investment
bank and the Board of Directors shall direct such independent appraiser to
conduct an appraisal and make a report on the Current Market Price of a share of
Common Stock within thirty (30) days of its appointment. The determination of
Current Market Price by such independent appraiser


                                       28

shall be final and binding upon the Corporation and the holders of Class B
Preferred. The costs of such independent appraiser shall be paid by the
Corporation. Any independent appraiser so utilized shall agree to treat all
information supplied by the Corporation in a confidential manner.

     (h) Statement Regarding Adjustments. Whenever the Conversion Price is
adjusted as herein provided:

          (i) the Corporation shall compute the adjusted Conversion Price in
     accordance with this Section 4 and shall prepare a certificate signed by
     the Treasurer of the Corporation setting forth the adjusted Conversion
     Price and the facts requiring such adjustment, and such certificate shall
     forthwith be filed at the office of the transfer agent or agents, if any,
     for the Class B Preferred and at the principal office of the Corporation;
     and

          (ii) a notice stating that the Conversion Price has been adjusted and
     setting forth the adjusted Conversion Price and the facts requiring such
     adjustment shall, as soon as practicable, be mailed to the holders of
     record of the outstanding Class B Preferred. Where appropriate, such notice
     may be given in advance and may be included as part of a notice required to
     be mailed under the provisions of Section 4(j).

     (i) Cancellation. All Class B Preferred which shall have been surrendered
for conversion as herein provided in this Section 4 shall no longer be deemed to
be outstanding and all rights with respect to such Class B Preferred, including
the rights, if any, to receive notices and to vote, shall forthwith cease and
terminate, except only the right of the holders thereof to receive Common Stock
or other assets or property in exchange therefor.

     (j) Notice to Holders. In the event that:

          (i) the Corporation shall take action to make any distribution or
     dividend to the holders of any class of its capital stock;

          (ii) the Corporation shall take action to offer for subscription pro
     rata to the holders of any class of its capital stock securities of any
     kind;

          (iii) the Corporation shall take action to accomplish any capital
     reorganization, or reclassification of the capital stock of the Corporation
     (other than a subdivision, split-up or combination of its Common Stock), or
     consolidation or merger to which the Corporation is a party and for which
     approval of any stockholders of the Corporation is required, or the sale or
     transfer of all or substantially all of the assets of the Corporation; or

          (iv) the Corporation shall take action looking to a voluntary or
     involuntary dissolution, liquidation or winding up of the affairs of the
     Corporation;



                                       29

   30



then the Corporation shall (x) in case of any such distribution, dividend or
offering of subscription rights, at least ten (10) days prior to the date or
expected date on which the books of the Corporation shall close or a record
shall be taken for the determination of holders entitled to such distribution or
subscription rights, and (y) in the case of any such reorganization,
reclassification, consolidation, merger, sale, transfer, dissolution,
liquidation or winding up, at least ten (10) days prior to the date or expected
date when the same shall take place, cause written notice thereof to be mailed
to each holder of Class B Preferred at such holder's address as shown on the
books of the Corporation. The notice to be given in accordance with this Section
4(j) shall also specify (x) the date or expected date on which the holders of
any class of the Corporation's capital stock shall be entitled thereto, and (y)
the date or expected date on which the holders of any class of the Corporation's
capital stock shall be entitled to exchange their shares for securities or other
property deliverable upon such reorganization, reclassification, consolidation,
merger, sale, transfer, dissolution, liquidation or winding up, as the case may
be.

     (k) Reservation of Shares. The Corporation shall at all times reserve and
keep available, free from preemptive rights, out of its treasury shares or its
authorized but unissued Common Stock, for the purpose of effecting the
conversion of the Class B Preferred, the full number of shares of Common Stock
then deliverable upon the conversion of all Class B Preferred then outstanding.

     (l) Reclassification of Common Stock. For the purposes of this Section 4,
the term "Common Stock" shall mean (i) the class of stock designated as the
Common Stock of the Corporation on the date of this Amended and Restated
Certificate of Incorporation is filed with the Secretary of State of Delaware,
or (ii) any other class of stock resulting from successive changes or
reclassifications of such Common Stock consisting solely of changes in par value
or from no par value to par value, or from par value to no par value. If at any
time as a result of an adjustment made pursuant to the provisions of Section
4(f)(v), the holder of any Class B Preferred thereafter surrendered for
conversion shall become entitled to receive any shares of the Corporation other
than Common Stock, and the number of such other shares so receivable upon
conversion of any Class B Preferred shall be subject to adjustment from time to
time in a manner and on terms as nearly equivalent as practicable to the
provisions with respect to the Common Stock contained in Section 4(f)(v), and
the other provisions of this Section 4 with respect to the Common Stock shall
apply on like terms to any such other shares.

     (m) Treasury Shares. For the purpose of this Section 4, the sale or other
disposition of any Common Stock of the Corporation theretofore held in its
treasury shall be deemed to be an issuance thereof.

     (n) Approvals. If any Common Stock to be reserved for the purpose of
conversion of Class B Preferred requires registration with or approval of any
governmental authority under any Federal or state law or of the NASDAQ System
before such shares may be validly issued or delivered upon conversion, the
Corporation will in good faith and as expeditiously as possible secure such
registration or approval, as the case may be. If, and so long as, any Common
Stock into which the Class B Preferred are then convertible are listed on any
national securities exchange, the Corporation will, if


                                       30

   31



permitted by the rules of such exchange, list and keep listed on such exchange,
upon official notice of issuance, all of such Common Stock issuable upon
conversion.

     (o) Valid Issuance. All Common Stock that may be issued upon conversion of
the Class B Preferred will upon issuance by the Corporation be duly and validly
issued, fully paid and nonassessable and free from all taxes, liens and charges
with respect to the issuance thereof, and the Corporation shall take no action
which will cause a contrary result (including, without limitation, any action
which would cause the Conversion Price to be less than the par value, if any, of
the Common Stock).

CLASS C CONVERTIBLE PREFERRED STOCK

     votes which it would have had the right to cast had all of its or his Class
     C Preferred been converted, as provided in Section 4, into Common Stock
     ("As Converted Basis") as of the record date of the meeting at which such
     votes are to be cast or as of the date any written consent is taken,
     including any fraction of a share of Common Stock into which a holder's
     Class C Preferred would be convertible. Holders of Class C Preferred shall
     not have any right to vote their shares as a separate class, except as may
     be otherwise required by the laws of the State of Delaware or as provided
     herein. Each record holder of Class C Preferred shall be entitled to notice
     of all meetings or actions of stockholders.

          (b) Notwithstanding anything herein to the contrary contained in
     Section 1(a), so long as any Class C Preferred remains outstanding, the
     Corporation shall not, without the affirmative vote by (or written consent
     of) the holders of at least seventy-five percent (75%) of the then
     outstanding Class C Preferred, voting as a single class on an As Converted
     Basis, and such further affirmative vote, if any, of the holders of any
     class of preferred shares as may be otherwise required by the laws of the
     State of Delaware or this Amended and Restated Certificate of
     Incorporation:

          (i) amend this Amended and Restated Certificate of Incorporation or
     the By-laws of the Corporation in any manner that would or could prejudice

     consolidation of the Corporation) that does any of the following:

               (A) increases or decreases the par value of the issued Class C
          Preferred;

               (B) changes issued Class C Preferred into a lesser number of

          then authorized;

               (C) changes the terms, or adds terms, of the Class C Preferred in
          any manner prejudicial to the holders of such shares;



                                       32

   33



               (D) changes the terms of issued shares of any class senior,
          junior or pari passu to the Class C Preferred in any manner
          prejudicial to the holders of the Class C Preferred;

               (E) authorizes shares of another class that are convertible into,
          or authorizes the conversion of shares of another class into, Class C
          Preferred or authorizes the Directors to fix or alter conversion
          rights of shares of another class that are convertible into Class C
          Preferred;

               (F) provides, in the case of an amendment described in Section
          1(b)(i)(A) or (B), that the stated capital of the Corporation shall be
          reduced or eliminated as a result of the amendment, or provides, in
          the case of Section 1(b)(i)(E), that the stated capital of the
          Corporation shall be reduced or eliminated upon the exercise of such
          conversion rights; provided that any such reduction or elimination is
          consistent with Section 244 of the Delaware General Corporation Law;

               (G) changes substantially the purposes of the Corporation, or
          provides that thereafter an amendment to this Amended and Restated
          Certificate of Incorporation may be adopted that changes substantially
          the purposes of the Corporation; or

               (H) changes the Corporation into a nonprofit corporation.

          (ii) Authorize, issue or sell or obligate itself to authorize, issue
     or sell any class of its capital stock or other securities (including debt
     securities) convertible into or exercisable for any equity security which
     ranks senior or pari passu in right, either as to voting, dividends or upon
     liquidation or otherwise, with the Class C Preferred.

     (c) Notwithstanding anything herein to the contrary contained in Section
1(a) or (b), so long as any Group I Preferred Stock remains outstanding, the
Corporation shall not, without the affirmative vote by the holders of at least
seventy-five percent (75%) of the then outstanding Group I Preferred Stock on an
As Converted Basis, effect (i) any sale, lease, assignment, transfer or other
conveyance of all or substantially all of the assets or capital stock of the
Corporation, (ii) any recapitalization, reclassification, reorganization or any
similar transaction with respect to any of its shares of capital stock, (iii)
any consolidation or merger involving the Corporation or (iv) effect any
transaction or series of related transactions in which more than fifty percent
(50%) of the voting power of the Corporation is disposed of.

2.   Dividend Rights.

     (a) The holders of outstanding Class C Preferred shall be entitled to
receive dividends at the rate of 8% per annum, payable out of funds legally
available therefor, prior and in preference to any declaration or payment of any
dividend on the Class A Preferred, Class B Preferred, Class D Preferred, Class E
Preferred, Class F Preferred, Class G Preferred or Common Stock or any shares of
any class of capital stock of the


                                       33

   34



Corporation. The dividends provided for in this Section 2(a) shall be cumulative
from the date of issuance, whether or not at the time such dividends shall
accrue or become due or at any other time there shall be profits, surplus or
other funds of the Corporation legally available for the payment of dividends.
Accumulations of accrued dividends shall be compounded annually at the rate of
8% per annum. For purposes of this Section 2(a), the date on which the
Corporation shall initially issue any Class C Preferred shall be deemed to be
the date of issuance of such Class C Preferred regardless of how many times
transfer of such Class C Preferred shall be made on stock records maintained by
or for the Corporation and regardless of the number of certificates which may be
issued to evidence such Class C Preferred (whether by reason of transfers of
such Class C Preferred or for any other reason).

     (b) The dividends shall accrue until and be paid upon the earliest to occur
of: (i) an initial public offering of Common Stock pursuant to an effective
registration statement under the Securities Act of 1933, as amended (an "IPO"),
(ii) a sale, conveyance, exchange or transfer (for cash, shares of stock,
securities or other consideration) of all or substantially all the property and
assets of the Corporation, (iii) the consolidation or merger of the Corporation
with or into any other corporation or corporations, or (iv) the liquidation of
the Corporation. Notwithstanding the foregoing, in the case of an event
specified in clause (ii), (iii) or (iv) of this Section 2(b), the proceeds or
consideration which would otherwise be paid in such event to the holders of
Class C Preferred shall be increased by the amount of all accrued unpaid
dividends thereon instead of such accrued amount being declared and paid as
dividends. In the event of an IPO, the Corporation may, at its option, pay the
accrued and unpaid dividends in Common Stock which Common Stock shall be valued
for this purpose at the price paid by the public. If any dividend on the
outstanding Class C Preferred shall for any reason not be paid at the time such
dividend shall become due, then such dividend in arrears shall be paid as soon
as payments of same shall be legally permissible. Until such dividend in arrears
is paid, dividends shall continue to accrue on the outstanding Class C
Preferred.

     (c) In addition to the dividends provided for in Section 2(a), the holders
of outstanding Class C Preferred shall be entitled to receive, when, as and if
declared by the Board of Directors from funds legally available therefor, a
portion of any dividends declared on Common Stock; provided, that for the
purpose of determining the amount of any such dividend payable to the holders of
Class C Preferred, such holders shall be entitled to receive a proportionate
amount of such dividends as if all issued and outstanding Class C Preferred had
been converted into Common Stock as of the record date for the determination of
holders entitled to receive said dividend.

3.   Liquidation Rights.

     (a) Upon the dissolution, liquidation or winding up of the affairs of the
Corporation, whether voluntary or involuntary, or the sale, conveyance, exchange
or transfer (for cash, shares of stock, securities or other consideration) of
all or substantially all the property and assets of the Corporation, or the
reorganization, consolidation or merger of the Corporation with or into any
other company or companies, or a transaction or series of related transactions
in which more than fifty percent (50%) of the voting


                                       34

   35



power of the Corporation is disposed of or sold (whether by the Corporation or

     3(a)(i)-(ii), the holders of Class A Preferred shall receive cash in the
     amount of 63/100 Dollars ($0.63) per share, plus an amount equal to
     declared but unpaid dividends on such shares; the holders of Class B
     Preferred shall receive cash in the amount of One and 25/100 Dollars

     proviso, the aggregate amount payable to the holders of Class E Preferred
     pursuant to this Section 3(a)(ii) shall not exceed Five Million Dollars
     ($5,000,000); provided, further, that if the holders of Class E Preferred
     shall have purchased additional shares of Common Stock pursuant to the

     forth in the immediately preceding proviso shall be increased by the
     aggregate amount actually paid for such Common Stock; the holders of Class
     G Preferred shall receive cash in the amount of One and 85/100 Dollars
     ($1.85) per share, plus an amount equal to declared but unpaid dividends on

     setting the terms of such shares;

                                       35

   36



     Class E Liquidation Preference Amount, less (y) the aggregate payments
     received by the holders of Class E Preferred pursuant to Section 3(a)(iii);

          (v) After payment to the holders of Preferred Stock of their

     Restated Certificate of Incorporation was filed with the Secretary of State
     of the State of Delaware (not including Common Stock issued upon conversion
     of Preferred Stock) shall receive cash in the amount of the original
     amounts for which such Common Stock was issued, which will be distributed
     ratably in proportion to the number of shares of Common Stock held by such
     holder, but in no event shall the aggregate amount payable to the holders
     of the Common Stock pursuant to this Section 3(a)(v) exceed One Million One

     receive cash in an amount equal to their pro-rata portion (using the number
     of shares the vested option holder would have if the options had been
     exercised at the then current exercise price) of Two Million Dollars
     ($2,000,000);

          (vii) After the payments set forth in Sections 3(a)(i)-(vi), all
     remaining assets of the Corporation shall be distributed ratably to the
     holders of outstanding shares of Common Stock in proportion to the number
     of shares of Common Stock held by such holders.

     If, upon any such event, the Corporation has insufficient funds to pay the
amounts payable under Section 3(a)(i) to the holders of all the outstanding
Class F Preferred, the holders of Class F Preferred shall share ratably in any
distribution of assets in proportion to the full amounts to which they would
otherwise be respectively entitled. Further, in the event that the holders of

   37



     (c) In the event (i) the holders of the Class C Preferred vote to convert
their shares of Class C Preferred into Common Stock immediately prior to or in
connection with an event specified in Section 3(a) or (ii) any holder of Class C
Preferred otherwise converts their shares of Class C Preferred into Common Stock
in accordance with such holder's rights under Section 4, the priorities and
preferences set forth in Section 3(a) shall be of no further effect and the
holders of such Common Stock shall share all of the assets of the Corporation
available for distribution to all holders of Common Stock ratably in proportion
to the number of shares of Common Stock held by them respectively.

4.   Conversion Rights.

     (a) Conversion. The holder of each outstanding Class C Preferred shall,
subject to the terms and conditions hereinafter set forth, convert such Class C
Preferred into fully paid and nonassessable shares of Common Stock at the
Conversion Price (as defined in Section 4(b)) in effect on the Conversion Date
(as defined in Section 4(c)), at the following times and pursuant to the
following conditions: (i) at any time, at such stockholder's option; (ii)
automatically and simultaneously upon the Closing of a Public Offering; or (iii)
upon the written notice to the Corporation at the election by the holders of
seventy-five percent (75%) of the outstanding Class C Preferred, voting on an As
Converted Basis.

     (b) Conversion Price. Each Class C Preferred shall be convertible at an
office or agency referred to below into a number of fully paid and nonassessable
shares of Common Stock (calculated as to each conversion to the nearest
one-hundredth (1/100th) of a share) as is determined by dividing Three and
67/100 Dollars ($3.67) by the Conversion Price in effect on the Conversion Date.
As of the date this Amended and Restated Certificate of Incorporation was filed
with the Secretary of State of Delaware, the price at which Common Stock shall
initially be issuable upon conversion shall be Three and 67/100 Dollars ($3.67)
per share, which price may be adjusted from time to time as provided in Section
4(f) (the "Conversion Price").

     (c) Method of Conversion. In order to exercise such conversion privilege,
the holder of any Class C Preferred to be converted shall present and surrender
the certificate(s) representing such Class C Preferred during usual business
hours at any office or agency of the Corporation maintained for the transfer of
Class C Preferred and shall deliver a written notice of its election to convert
the Class C Preferred represented by such certificate(s), or any portion
thereof, specified in such notice. Such notice shall also state the name or
names (with address) in which the certificate or certificates for Common Stock
issuable on such conversion shall be issued. If so required by the Corporation,
any certificate for Class C Preferred surrendered for conversion shall be
accompanied by instruments of transfer, in form satisfactory to the Corporation,
duly executed by the holder of such Class C Preferred or such holder's duly
authorized representative. Each conversion of Class C Preferred shall be deemed
to have been effected on the date (the "Conversion Date") on which the
certificate or certificates representing such Class C Preferred shall have been
surrendered and any required notice and instruments of transfer received as
aforesaid. Subject to the provisions of Section 4(f)(ix), the person or persons
in whose name or names any certificate or certificates for


                                       37

   38



Common Stock shall be issuable upon such conversion shall be deemed to have
become the holder or holders of record of such Common Stock immediately prior to
the close of business on the Conversion Date. Subject to the provisions of
Section 4(f)(ix), as promptly as practicable (and in any event within two (2)
business days) after the presentation and surrender for conversion, as herein
provided, of any certificate for Class C Preferred, the Corporation shall issue
and deliver at such office or agency, to or upon the written order of the holder
thereof, a certificate or certificates for the number of shares of Common Stock
issuable upon such conversion. In case any certificate for Class C Preferred
shall be surrendered for conversion of less than all of the Class C Preferred
represented thereby, the Corporation shall deliver at such office or agency, to
or upon the written order of the holder thereof, a certificate or certificates
for the number of Class C Preferred represented by such surrendered certificate
which are not converted. The issuance of certificates for Common Stock issuable
upon the conversion of Class C Preferred, and the issuance of certificates
representing Class C Preferred which are not converted as described above, shall
be at the Corporation's expense and without charge to the converting holder for
any tax imposed on the Corporation in respect of the issue thereof. The
Corporation shall not, however, be required to pay any tax which may be payable
with respect to any transfer involved in the issue and delivery of any
certificate in a name other than that of the holder of the Class C Preferred and
the Corporation shall not be required to issue or deliver any such certificate
unless and until the person requesting the issue thereof shall have paid to the
Corporation the amount of such tax or has established to the satisfaction of the
Corporation that such tax has been paid.

     (d) No Adjustment for Dividends. With respect to any conversion of Class C
Preferred into Common Stock pursuant to this Section 4, no adjustment shall be
made for dividends declared but as yet unpaid on the Class C Preferred as of any
record date prior to the Conversion Date; provided, however, that upon the
conversion of such Class C Preferred, the dividend declared but as yet unpaid on
the Class C Preferred shall be payable on the Common Stock issued upon such
conversion as if such Common Stock were outstanding as of the record date for
the determination of holders entitled to receive said dividend.

     (e) Fractional Shares. If more than one Class C Preferred share shall be
surrendered for conversion at one time by the same holder, the number of full
shares of Common Stock issuable upon conversion thereof shall be computed on the
basis of the aggregate number of Class C Preferred shares so surrendered. If any
fractional interest in a share of Common Stock would be deliverable upon the
conversion of any Class C Preferred, the Corporation shall issue a certificate
which shall evidence and include such fractional interest in the share of Common
Stock.

     (f) Conversion Price Adjustments. The Conversion Price for the Class C
Preferred shall be subject to adjustment from time to time as follows:

          (i) Common Stock Issued at Less Than the Conversion Price. In the
     event that the Corporation shall issue Additional Common Shares (as defined
     in Article 4, Section C. 4(f)(i) of this Amended and Restated Certificate
     of Incorporation) without consideration or for a consideration per share
     less than the Conversion Price in effect immediately prior to such
     issuance, and a holder of


                                       38

   39



     Class C Preferred shall have participated pro-rata on an As Converted Basis
     in such financing (the "Participating Holder"), the Conversion Price in
     effect immediately prior to each such issuance for the Participating
     Holder's Class C Preferred shall be reduced to the lowest price per share
     at which such Additional Common Shares shall have been issued.

               For the purposes of any adjustment of the Conversion Price
     pursuant to Section 4(f), the following provisions shall be applicable:

               (A) Cash. In the case of the issuance of Common Stock for cash,
          the amount of the consideration received by the Corporation shall be
          deemed to be the amount of the cash proceeds received by the
          Corporation for such Common Stock before deducting therefrom any
          reasonable discounts, commissions, taxes or other expenses allowed,
          paid or incurred by the Corporation for any underwriting or otherwise
          in connection with the issuance and sale thereof.

               (B) Consideration Other Than Cash. In the case of the issuance of
          Common Stock (other than upon the conversion of shares of capital
          stock or other securities of the Corporation) for a consideration in
          whole or in part other than cash, including securities acquired in
          exchange therefor (other than securities by their terms so
          exchangeable), the consideration other than cash shall be deemed to be
          the fair value thereof (as determined in good faith by the Board of
          Directors of the Corporation, whose determination shall be conclusive
          to the extent reasonable), irrespective of any accounting treatment;
          provided, that such fair value as determined by the Board of Directors
          shall not exceed the aggregate Current Market Price (as defined in
          Section 4(g)) of the Common Stock being issued as of the date the
          Board of Directors authorizes the issuance of such Common Stock.

               (C) Options and Convertible Securities. In the case of the
          issuance of (i) options, warrants or other rights to purchase or
          acquire Common Stock (whether or not at the time exercisable) other
          than Excluded Shares, (ii) securities by their terms convertible into
          or exchangeable for Common Stock (whether or not at the time so
          convertible or exchangeable) or (iii) options, warrants or rights to
          purchase such convertible or exchangeable securities (whether or not
          at the time exercisable):

                    (1) the aggregate maximum number of shares of Common Stock
               deliverable upon exercise of such options, warrants or other
               rights to purchase or acquire Common Stock shall be deemed to
               have been issued at the time such options, warrants or other
               rights become exercisable and for a consideration equal to the
               consideration (determined in the manner provided in Sections
               4(f)(iii)(A) and (B)), if any, received by the Corporation upon
               the issuance of such options, warrants or other rights plus the


                                       39

   40



               minimum purchase price provided in such options, warrants or
               other rights for the Common Stock covered thereby;

                    (2) the aggregate maximum number of shares of Common Stock
               deliverable upon conversion of or in exchange for any such
               convertible or exchangeable securities, or upon the exercise of
               options, warrants or other rights to purchase or acquire such
               convertible or exchangeable securities and the subsequent
               conversion or exchange thereof, shall be deemed to have been
               issued at the time such securities become convertible or
               exchangeable or such options, warrants or other rights become
               exercisable and for a consideration equal to the consideration,
               if any, received by the Corporation for any such securities and
               related options, warrants or other rights (excluding any cash
               received on account of accrued interest or accrued dividends),
               plus the additional consideration, if any, to be received by the
               Corporation upon the conversion or exchange of such securities
               and the exercise of any related options, warrants or other rights
               (the consideration in each case to be determined in the manner
               provided in Sections 4(f)(iii)(A) and (B));

                    (3) on any change in the number of shares of Common Stock
               deliverable upon exercise of any such options, warrants or other
               rights which have become exercisable or conversion of or exchange
               of such convertible or exchangeable securities which have become
               convertible or exchangeable, or any change in the consideration
               to be received by the Corporation upon such exercise, conversion
               or exchange, including, but not limited to, a change resulting
               from any subdivision, split-up, combination or reclassification
               thereof, the Conversion Price as then in effect shall forthwith
               be readjusted to such Conversion Price as would have been
               obtained had an adjustment been made upon such options, warrants
               or other rights not exercised becoming exercisable prior to such
               change, or securities not converted or exchanged becoming
               convertible or exchangeable prior to such change, upon the basis
               of such change but only if as a result of such adjustment the
               Conversion Price then in effect is thereby reduced;

                    (4) on the expiration or cancellation of any such options,
               warrants or other rights, or the termination of the right to
               convert or exchange such convertible or exchangeable securities,
               if the Conversion Price shall have been adjusted upon such
               becoming exercisable, convertible or exchangeable, such
               Conversion Price shall forthwith be readjusted to such Conversion
               Price as would have been obtained had an adjustment been made
               upon such options, warrants or other rights becoming exercisable
               or securities becoming convertible or exchangeable on the basis
               of the issuance of only the number of shares of Common Stock
               actually issued


                                       40

   41



               upon the exercise of such options, warrants or other rights, or
               upon the conversion or exchange of such securities; and

                    (5) if the Conversion Price shall have been adjusted upon
               such options, warrants or other rights becoming exercisable or
               such convertible or exchangeable securities becoming convertible
               or exchangeable, no further adjustment of the Conversion Price
               shall be made for the actual issuance of Common Stock upon the
               exercise, conversion or exchange thereof.

          (ii) Excluded Shares. "Excluded Shares" has the meaning given to it in
     Article 4, Section C. 4(f)(ii) of this Amended and Restated Certificate of
     Incorporation.

          (iii) Stock Dividends; Stock Splits, Etc. If the number of shares of
     Common Stock outstanding at any time after the date of issuance of the
     Class C Preferred is increased by a stock dividend payable in Common Stock
     or by a subdivision or split-up of Common Stock, then immediately after the
     record date fixed for the determination of holders of Common Stock entitled
     to receive such stock dividend or the effective date of such subdivision or
     split-up, as the case may be, the Conversion Price shall be appropriately
     adjusted so that the holder of any Class C Preferred thereafter converted
     shall be entitled to receive the number of shares of Common Stock of the
     Corporation which such holder would have owned immediately following such
     action had such Class C Preferred been converted immediately prior thereto.

          (iv) Combination of Shares. If the number of shares of Common Stock
     outstanding at any time after the date of issuance of the Class C Preferred
     is decreased by a combination of the outstanding Common Stock, then
     immediately after the effective date of such combination, the Conversion
     Price shall be appropriately increased so that the holder of any Class C
     Preferred thereafter converted shall be entitled to receive the number of
     shares of Common Stock of the Corporation which such holder would have
     owned immediately following such action had such Class C Preferred been
     converted immediately prior thereto.

          (v) Reorganizations, Etc. In the case of any capital reorganization of
     the Corporation, any reclassification of Common Stock, the consolidation of
     the Corporation with or the merger of the Corporation with or into any
     other entity (other than a reorganization or merger solely for the purpose
     of the change in the state of incorporation of the Corporation) or the
     sale, lease or other transfer of all or substantially all of the assets of
     the Corporation to any other person or entity, each Class C Preferred shall
     after such capital reorganization, reclassification, consolidation, merger,
     sale, lease or other transfer be convertible into the number of shares of
     capital stock or other securities or property to which the Common Stock
     issuable (at the time of such capital reorganization, reclassification,
     consolidation, merger, sale, lease or other transfer) upon conversion of
     such Class C Preferred would have been entitled upon such capital
     reorganization, reclassification, consolidation, merger, sale, lease or
     other transfer (taking into


                                       41

   42



     account any adjustment pursuant to Section 4(f)(ii)); and in any such case,
     if necessary, the provisions set forth herein with respect to the rights
     and interests thereafter of the holders of the Class C Preferred shall be
     appropriately adjusted so as to be applicable, as nearly as may reasonably
     be possible, to any shares of capital stock or other securities or property
     thereafter deliverable on the conversion of the Class C Preferred. The
     subdivision or combination of Common Stock issuable upon conversion of
     Class C Preferred at any time outstanding into a greater or lesser number
     of shares of Common Stock (whether with or without par value) shall not be
     deemed to be a reclassification of the Common Stock of the Corporation for
     the purposes of this Section 4(f)(vii).

          (vi) Evidences of Indebtedness or Assets. In case the Corporation
     shall declare a distribution payable in securities of other Persons,
     evidences of indebtedness issued by the Corporation or other Persons or
     assets (excluding cash dividends or dividends payable solely in Common
     Stock) then, in each such case, each holder of Class C Preferred shall be
     entitled to receive a proportionate share of any such distribution as if it
     had converted into the number of shares of Common Stock of the Corporation
     into which its Class C Preferred would have been convertible as of the
     record date fixed for the determination of the holders of outstanding
     shares of Common Stock of the Corporation entitled to receive such
     distribution.

          (vii) Rounding of Calculations; Minimum Adjustment. All calculations
     under this Section 4(f) shall be made to the nearest cent or to the nearest
     one-hundredth (1/100th) of a share, as the case may be. Any provision of
     this Section 4 to the contrary notwithstanding, no adjustment in the
     Conversion Price shall be made if the amount of such adjustment would be
     less than one cent ($0.01), but any such amount shall be carried forward
     and an adjustment with respect thereto shall be made at the time of, and
     together with, any subsequent adjustment which, together with such amount
     and any other amount or amounts so carried forward, shall aggregate one
     cent ($0.01) or more.

          (viii) Timing of Issuance of Additional Common Shares Upon Certain
     Adjustments. In any case in which the provisions of this Section 4(f) shall
     require that an adjustment shall become effective immediately after the
     record date for an event, the Corporation may defer until the occurrence of
     such event the issuing to the holder of any Class C Preferred converted
     after such record date and before the occurrence of such event the
     Additional Common Shares issuable upon such conversion by reason of the
     adjustment required by such event over and above the Common Stock issuable
     upon such conversion before giving effect to such adjustment; provided,
     that the Corporation upon request shall deliver to such holder a due bill
     or other appropriate instrument evidencing such holder's right to receive
     such additional shares upon the occurrence of the event requiring such
     adjustment.

          (ix) Applicable Adjustment. In any case in which the provisions of
     this Section 4(f) shall require an adjustment to the Conversion Price for
     the Class C Preferred, the applicable adjustment shall be the largest
     adjustment lowering the


                                       42

   43



     Conversion Price resulting from the application of any appropriate
     provision of this Section 4(f) to such event.

          (g) Current Market Price. "Current Market Price" shall have the
     meaning given in Article 4, Section C. 4.(g) of this Amended and Restated
     Certificate of Incorporation; provided, that, if within fifteen (15) days
     of receiving notice of an event under Section 4(f) requiring the
     calculation of the Current Market Price a holder of at least ten percent
     (10%) of the currently outstanding Class C Preferred requests the
     appointment of an independent appraiser, the Board of Directors shall,
     within ten (10) days of such request, appoint as an independent appraiser a
     nationally-known independent public accounting firm or investment bank and
     the Board of Directors shall direct such independent appraiser to conduct
     an appraisal and make a report on the Current Market Price of a share of
     Common Stock within thirty (30) days of its appointment. The determination
     of Current Market Price by such independent appraiser shall be final and
     binding upon the Corporation and the holders of Class C Preferred. The
     costs of such independent appraiser shall be paid by the Corporation. Any
     independent appraiser so utilized shall agree to treat all information
     supplied by the Corporation in a confidential manner.

          (h) Statement Regarding Adjustments. Whenever the Conversion Price is
     adjusted as herein provided:

               (i) the Corporation shall compute the adjusted Conversion Price
          in accordance with this Section 4 and shall prepare a certificate
          signed by the Treasurer of the Corporation setting forth the adjusted
          Conversion Price and the facts requiring such adjustment, and such
          certificate shall forthwith be filed at the office of the transfer
          agent or agents, if any, for the Class C Preferred and at the
          principal office of the Corporation; and

               (ii) a notice stating that the Conversion Price has been adjusted
          and setting forth the adjusted Conversion Price and the facts
          requiring such adjustment shall, as soon as practicable, be mailed to
          the holders of record of the outstanding Class C Preferred. Where
          appropriate, such notice may be given in advance and may be included
          as part of a notice required to be mailed under the provisions of
          Section 4(j).

          (i) Cancellation. All Class C Preferred which shall have been
     surrendered for conversion as herein provided in this Section 4 shall no
     longer be deemed to be outstanding and all rights with respect to such
     Class C Preferred, including the rights, if any, to receive notices and to
     vote, shall forthwith cease and terminate, except only the right of the
     holders thereof to receive Common Stock or other assets or property in
     exchange therefor.

          (j) Notice to Holders. In the event that:

               (i) the Corporation shall take action to make any distribution or
          dividend to the holders of any class of its capital stock;



                                       43

   44



               (ii) the Corporation shall take action to offer for subscription
          pro rata to the holders of any class of its capital stock securities
          of any kind;

               (iii) the Corporation shall take action to accomplish any capital
          reorganization, or reclassification of the capital stock of the
          Corporation (other than a subdivision, split-up or combination of its
          Common Stock), or consolidation or merger to which the Corporation is
          a party and for which approval of any stockholders of the Corporation
          is required, or the sale or transfer of all or substantially all of
          the assets of the Corporation; or

               (iv) the Corporation shall take action looking to a voluntary or
          involuntary dissolution, liquidation or winding up of the affairs of
          the Corporation; then the Corporation shall (x) in case of any such
          distribution, dividend or offering of subscription rights, at least
          ten (10) days prior to the date or expected date on which the books of
          the Corporation shall close or a record shall be taken for the
          determination of holders entitled to such distribution or subscription
          rights, and (y) in the case of any such reorganization,
          reclassification, consolidation, merger, sale, transfer, dissolution,
          liquidation or winding up, at least ten (10) days prior to the date or
          expected date when the same shall take place, cause written notice
          thereof to be mailed to each holder of Class C Preferred at such
          holder's address as shown on the books of the Corporation. The notice
          to be given in accordance with this Section 4(j) shall also specify
          (x) the date or expected date on which the holders of any class of the
          Corporation's capital stock shall be entitled thereto, and (y) the
          date or expected date on which the holders of any class of the
          Corporation's capital stock shall be entitled to exchange their shares
          for securities or other property deliverable upon such reorganization,
          reclassification, consolidation, merger, sale, transfer, dissolution,
          liquidation or winding up, as the case may be.

          (k) Reservation of Shares. The Corporation shall at all times reserve
     and keep available, free from preemptive rights, out of its treasury shares
     or its authorized but unissued Common Stock, for the purpose of effecting
     the conversion of the Class C Preferred, the full number of shares of
     Common Stock then deliverable upon the conversion of all Class C Preferred
     then outstanding.

          (l) Reclassification of Common Stock. For the purposes of this Section
     4, the term "Common Stock" shall mean (i) the class of stock designated as
     the Common Stock of the Corporation on the date this Amended and Restated
     Certificate of Incorporation is filed with the Secretary of State of
     Delaware, or (ii) any other class of stock resulting from successive
     changes or reclassifications of such Common Stock consisting solely of
     changes in par value or from no par value to par value, or from par value
     to no par value. If at any time as a result of an adjustment made pursuant
     to the provisions of Section 4(f)(v), the holder of any Class C Preferred
     thereafter surrendered for conversion shall become entitled to receive any
     shares of the Corporation other than shares of Common Stock, and the number
     of such other shares so receivable upon conversion of any Class C Preferred
     shall be subject to adjustment from time to time in a manner and on terms
     as nearly equivalent as practicable to the provisions with respect to the
     Common


                                       44

   45



     Stock contained in Section 4(f)(v), and the other provisions of this
     Section 4 with respect to the Common Stock shall apply on like terms to any
     such other shares.

          (m) Treasury Shares. For the purpose of this Section 4, the sale or
     other disposition of any Common Stock of the Corporation theretofore held
     in its treasury shall be deemed to be an issuance thereof.

          (n) Approvals. If any Common Stock to be reserved for the purpose of
     conversion of Class C Preferred requires registration with or approval of
     any governmental authority under any Federal or state law or of the NASDAQ
     System before such shares may be validly issued or delivered upon
     conversion, the Corporation will in good faith and as expeditiously as
     possible secure such registration or approval, as the case may be. If, and
     so long as, any Common Stock into which the Class C Preferred are then
     convertible are listed on any national securities exchange, the Corporation
     will, if permitted by the rules of such exchange, list and keep listed on
     such exchange, upon official notice of issuance, all of such Common Stock
     issuable upon conversion.

          (o) Valid Issuance. All Common Stock that may be issued upon
     conversion of the Class C Preferred will upon issuance by the Corporation
     be duly and validly issued, fully paid and nonassessable and free from all
     taxes, liens and charges with respect to the issuance thereof, and the
     Corporation shall take no action which will cause a contrary result
     (including, without limitation, any action which would cause the Conversion
     Price to be less than the par value, if any, of the Common Stock).


F.   TERMS OF CLASS D CONVERTIBLE PREFERRED STOCK

     The following is a statement of the express terms, powers, preferences,
rights, qualifications, limitations and restrictions in respect of the shares of
the Class D Preferred. Except as otherwise expressly provided in this Section F
of this Article Fourth ("Section F"), references to "Sections" in this Section F
shall be references to Sections within this Section F.

CLASS D CONVERTIBLE PREFERRED STOCK

     1.   Voting Rights.

          (a) Holders of Class D Preferred shall be entitled to vote on any and
     all matters submitted to a vote of the stockholders. For such purposes,
     each holder of Class D Preferred shall be entitled to cast the number of
     votes which it would have had the right to cast had all of its or his Class
     D Preferred been converted, as provided in Section 4, into Common Stock
     ("As Converted Basis") as of the record date of the meeting at which such
     votes are to be cast or as of the date any written consent is taken,
     including any fraction of a share of Common Stock into which a holder's
     Class D Preferred would be convertible. Holders of Class D Preferred shall
     not have any right to vote their shares as a separate class, except as may
     be otherwise required by the laws of the State of Delaware or as provided
     herein. Each record holder of Class D Preferred shall be entitled to notice
     of all meetings or actions of stockholders.



                                       45

   46



          (b) Notwithstanding anything herein to the contrary contained in
     Section 1(a), so long as any Class D Preferred remains outstanding, the
     Corporation shall not, without the affirmative vote by (or written consent
     of) the holders of at least seventy-five percent (75%) of the then
     outstanding Convertible Preferred Shares, voting as a single class on an As
     Converted Basis, and such further affirmative vote, if any, of the holders

                    (G) changes substantially the purposes of the Corporation,
               or provides that thereafter an amendment to this Amended and
               Restated Certificate of Incorporation may be adopted that changes

     Stock as of the record date for the determination of holders entitled to
     receive said dividend.

          Section 3(a)(ii) shall not exceed Five Million Dollars ($5,000,000);
          provided, further, that if the holders of Class E Preferred shall have
          purchased additional shares of Common Stock pursuant to the terms of
          Section 1(h) of the Purchase Agreement, the aggregate amount set forth

          Class G Preferred shall receive cash in the amount of One and 85/100
          Dollars ($1.85) per share, plus an amount equal to declared but unpaid

                                       48

   49



               (v) After payment to the holders of Preferred Stock of their
          liquidation preference as set forth in Sections 3(a)(i)-(iv), the
          holders of outstanding shares of Common Stock as of the date of this
          Amended and Restated Certificate of Incorporation was filed with the
          Secretary of State of the State of Delaware (not including Common
          Stock issued upon conversion of Preferred Stock) shall receive cash in
          the amount of the original amounts for which such Common Stock was
          issued, which will be distributed ratably in proportion to the number
          of shares of Common Stock held by such holder, but in no event shall
          the aggregate amount payable to the holders of the Common Stock
          pursuant to this Section 3(a)(v) exceed One Million One Hundred

               (vi) After payment to the holders of Preferred Stock and Common
          Stock (not including Common Stock issued upon conversion of Preferred

          Common Stock shall receive cash in an amount equal to their pro-rata
          portion (using the number of shares the vested option holder would
          have if the options had been exercised at the then current exercise
          price) of Two Million Dollars ($2,000,000);

               (vii) After the payments set forth in Sections 3(a)(i)-(vi),

          If, upon any such event, the Corporation has insufficient funds to pay
     the amounts payable under Section 3(a)(i) to the holders of all the
     outstanding Class F Preferred, the holders of Class F Preferred shall share
     ratably in any distribution of assets in proportion to the full amounts to
     which they would otherwise be respectively entitled. Further, in the event
     that the holders of the Class F Preferred shall have been paid all amounts
     payable under Section 3(a)(i) but the Corporation has insufficient funds to
     pay the amounts payable under Section 3(a)(ii) to the holders of all the
     outstanding Class C Preferred, the holders of Class C Preferred shall share

     shares of stock, securities or other consideration) of all or substantially
     all the property and assets of the Corporation, nor the consolidation or
     merger of the Corporation with or into any other corporation or
     corporations, nor the consolidation or merger of any other corporation or
     corporations with or into the Corporation, nor the reorganization of the
     Corporation, shall be deemed a liquidation, dissolution or winding up of
     the affairs of the Corporation within the meaning of this Section 3 if the
     holders of at least fifty-one percent (51%) of the then outstanding
     Convertible Preferred Shares and Class F Preferred


                                       49

   50



     together elect to have such events not deemed a liquidation of the
     Corporation by giving written notice to the Corporation.

          (c) After the payment in cash to the holders of Class D Preferred of
     the full preferential amount fixed in accordance with the provisions of
     Section 3(a) with respect to the outstanding Class D Preferred, the holders
     of outstanding Class D Preferred as such will have no right or claim to any
     of the remaining assets of the Corporation.

          (d) In the event (i) the holders of the Class D Preferred vote to
     convert their shares of Class D Preferred into Common Stock immediately
     prior to or in connection with an event specified in Section 3(a) or (ii)
     any holder of Class D Preferred otherwise converts their shares of Class D
     Preferred into Common Stock in accordance with such holder's rights under
     Section 4, the priorities and preferences set forth in Section 3(a) shall
     be of no further effect and the holders of such Common Stock shall share
     all of the assets of the Corporation available for distribution to all
     holders of Common Stock ratably in proportion to the number of shares of
     Common Stock held by them respectively.

     4.   Conversion Rights.

          (a) Conversion. The holder of each outstanding Class D Preferred
     shall, subject to the terms and conditions hereinafter set forth, convert
     such Class D Preferred into fully paid and nonassessable shares of Common
     Stock at the Conversion Price (as hereinafter defined in Section 4(b)) in
     effect on the Conversion Date (as defined in Section 4(c)), at the
     following times and pursuant to the following conditions: (a) at any time,
     at such stockholder's option; (b) automatically and simultaneously upon the
     Closing of a Public Offering; or (c) upon the written notice to the
     Corporation at the election by the holders of seventy-five percent (75%) of
     the outstanding Class D Preferred, voting on an As Converted Basis.

          (b) Conversion Price. Each Class D Preferred shall be convertible at
     an office or agency referred to below into a number of fully paid and
     nonassessable shares of Common Stock (calculated as to each conversion to
     the nearest one-hundredth (1/100th) of a share) as is determined by
     dividing One and 35/100 Dollars ($1.35) by the Conversion Price in effect
     on the Conversion Date. As of the date of this Amended and Restated
     Certificate of Incorporation was filed with the Secretary of State of
     Delaware, the price at which Common Stock shall initially be issuable upon
     conversion shall be One and 35/100 Dollars ($1.35) per share, which price
     may be adjusted from time to time as provided in Section 4(f) (the
     "Conversion Price").

          (c) Method of Conversion. In order to exercise such conversion
     privilege, the holder of any Class D Preferred to be converted shall
     present and surrender the certificate(s) representing such Class D
     Preferred during usual business hours at any office or agency of the
     Corporation maintained for the transfer of Class D Preferred and shall
     deliver a written notice of its election to convert the Class D Preferred
     represented by such certificate(s), or any portion thereof, specified in
     such notice. Such notice shall also state the name or names (with address)
     in which the certificate or certificates for Common Stock issuable on such
     conversion shall be issued. If so required by the


                                       50

   51



     Corporation, any certificate for Class D Preferred surrendered for
     conversion shall be accompanied by instruments of transfer, in form
     satisfactory to the Corporation, duly executed by the holder of such Class
     D Preferred or such holder's duly authorized representative. Each
     conversion of Class D Preferred shall be deemed to have been effected on
     the date (the "Conversion Date") on which the certificate or certificates
     representing such Class D Preferred shall have been surrendered and any
     required notice and instruments of transfer received as aforesaid. Subject
     to the provisions of Section 4(f)(viii), the person or persons in whose
     name or names any certificate or certificates for Common Stock shall be
     issuable upon such conversion shall be deemed to have become the holder or
     holders of record of such Common Stock immediately prior to the close of
     business on the Conversion Date. Subject to the provisions of Section
     4(f)(viii), as promptly as practicable after (and in any event within two
     (2) business days) the presentation and surrender for conversion, as herein
     provided, of any certificate for Class D Preferred, the Corporation shall
     issue and deliver at such office or agency, to or upon the written order of
     the holder thereof, a certificate or certificates for the number of shares
     of Common Stock issuable upon such conversion. In case any certificate for
     Class D Preferred shall be surrendered for conversion of less than all of
     the Class D Preferred represented thereby, the Corporation shall deliver at
     such office or agency, to or upon the written order of the holder thereof,
     a certificate or certificates for the number of Class D Preferred
     represented by such surrendered certificate which are not converted. The
     issuance of certificates for Common Stock issuable upon the conversion of
     Class D Preferred, and the issuance of certificates representing Class D
     Preferred which are not converted as described above, shall be at the
     Corporation's expense and without charge to the converting holder for any
     tax imposed on the Corporation in respect of the issue thereof. The
     Corporation shall not, however, be required to pay any tax which may be
     payable with respect to any transfer involved in the issue and delivery of
     any certificate in a name other than that of the holder of the Class D
     Preferred and the Corporation shall not be required to issue or deliver any
     such certificate unless and until the person requesting the issue thereof
     shall have paid to the Corporation the amount of such tax or has
     established to the satisfaction of the Corporation that such tax has been
     paid.

          (d) No Adjustment for Dividends. With respect to any conversion of
     Class D Preferred into Common Stock pursuant to this Section 4, no
     adjustment shall be made for dividends declared but as yet unpaid on the
     Class D Preferred as of any record date prior to the Conversion Date;
     provided, however, that upon the conversion of such Class D Preferred, the
     dividend declared but as yet unpaid on the Class D Preferred shall be
     payable on the Common Stock issued upon such conversion as if such Common
     Stock were outstanding as of the record date for the determination of
     holders entitled to receive said dividend.

          (e) Fractional Shares. If more than one Class D Preferred share shall
     be surrendered for conversion at one time by the same holder, the number of
     full shares of Common Stock issuable upon conversion thereof shall be
     computed on the basis of the aggregate number of Class D Preferred shares
     so surrendered. If any fractional interest in a share of Common Stock would
     be deliverable upon the conversion of any Class D Preferred, the
     Corporation shall issue a certificate which shall evidence and include such
     fractional interest in the share of Common Stock.



                                       51

   52



          (f) Conversion Price Adjustments. The Conversion Price for the Class D
     Preferred shall be subject to adjustment from time to time as follows:

               (i) Common Stock Issued at Less Than the Conversion Price. If the
          Corporation shall issue or be deemed to have issued any Common Stock
          other than Excluded Shares (as defined in Article 4, Section C.
          4(f)(ii) of this Amended and Restated Certificate of Incorporation)
          without consideration or for a consideration per share less than the
          Conversion Price in effect immediately prior to such issuance, the
          Conversion Price in effect immediately prior to each such issuance
          shall be reduced to a price determined by multiplying the then current
          Conversion Price by a fraction (A) the numerator of which shall be the
          sum of (1) the number of shares of Common Stock outstanding
          immediately prior to such issuance, plus (2) the number of shares of
          Common Stock that the aggregate consideration received by the Company
          for the total number of Additional Common Shares so issued would
          purchase at such Conversion Price, and (B) the denominator of which
          shall be the number of shares of Common Stock outstanding immediately
          prior to such issuance plus the number of Additional Common Shares so
          issued.

               For the purposes of any adjustment of the Conversion Price
          pursuant to this Section 4(f)(i), the following provisions shall be
          applicable:

                    (A) Cash. In the case of the issuance of Common Stock for
               cash, the amount of the consideration received by the Corporation
               shall be deemed to be the amount of the cash proceeds received by
               the Corporation for such Common Stock before deducting therefrom
               any reasonable discounts, commissions, taxes or other expenses
               allowed, paid or incurred by the Corporation for any underwriting
               or otherwise in connection with the issuance and sale thereof.

                    (B) Consideration Other Than Cash. In the case of the
               issuance of Common Stock (other than upon the conversion of
               shares of capital stock or other securities of the Corporation)
               for a consideration in whole or in part other than cash,
               including securities acquired in exchange therefor (other than
               securities by their terms so exchangeable), the consideration
               other than cash shall be deemed to be the fair value thereof (as
               determined in good faith by the Board of Directors of the
               Corporation, whose determination shall be conclusive to the
               extent reasonable), irrespective of any accounting treatment;
               provided, that such fair value as determined by the Board of
               Directors shall not exceed the aggregate Current Market Price (as
               defined in Section 4(g)) of the Common Stock being issued as of
               the date the Board of Directors authorizes the issuance of such
               Common Stock.

                    (C) Options and Convertible Securities. In the case of the
               issuance of (i) options, warrants or other rights to purchase or
               acquire Common Stock (whether or not at the time exercisable)
               other than Excluded Shares, (ii) securities by their terms
               convertible into or


                                       52

   53



               exchangeable for Common Stock (whether or not at the time so
               convertible or exchangeable) or (iii) options, warrants or rights
               to purchase such convertible or exchangeable securities (whether
               or not at the time exercisable):

                         (1) the aggregate maximum number of shares of Common
                    Stock deliverable upon exercise of such options, warrants or
                    other rights to purchase or acquire Common Stock shall be
                    deemed to have been issued at the time such options,
                    warrants or other rights become exercisable and for a
                    consideration equal to the consideration (determined in the
                    manner provided in Sections 4(f)(i)(A) and (B)), if any,
                    received by the Corporation upon the issuance of such
                    options, warrants or other rights plus the minimum purchase
                    price provided in such options, warrants or other rights for
                    the Common Stock covered thereby;

                         (2) the aggregate maximum number of shares of Common
                    Stock deliverable upon conversion of or in exchange for any
                    such convertible or exchangeable securities, or upon the
                    exercise of options, warrants or other rights to purchase or
                    acquire such convertible or exchangeable securities and the
                    subsequent conversion or exchange thereof, shall be deemed
                    to have been issued at the time such securities become
                    convertible or exchangeable or such options, warrants or
                    other rights become exercisable and for a consideration
                    equal to the consideration, if any, received by the
                    Corporation for any such securities and related options,
                    warrants or other rights (excluding any cash received on
                    account of accrued interest or accrued dividends), plus the
                    additional consideration, if any, to be received by the
                    Corporation upon the conversion or exchange of such
                    securities and the exercise of any related options, warrants
                    or other rights (the consideration in each case to be
                    determined in the manner provided in Sections 4(f)(i)(A) and
                    (B));

                         (3) on any change in the number of shares of Common
                    Stock deliverable upon exercise of any such options,
                    warrants or other rights which have become exercisable or
                    conversion of or exchange of such convertible or
                    exchangeable securities which have become convertible or
                    exchangeable, or any change in the consideration to be
                    received by the Corporation upon such exercise, conversion
                    or exchange, including, but not limited to, a change
                    resulting from any subdivision, split-up, combination or
                    reclassification thereof, the Conversion Price as then in
                    effect shall forthwith be readjusted to such Conversion
                    Price as would have been obtained had an adjustment been
                    made upon such options, warrants or other rights not
                    exercised becoming exercisable prior to such change, or
                    securities not converted or exchanged becoming convertible
                    or exchangeable prior to such change, upon the basis of


                                       53

   54



                    such change but only if as a result of such adjustment the
                    Conversion Price then in effect is thereby reduced;

                         (4) on the expiration or cancellation of any such
                    options, warrants or other rights, or the termination of the
                    right to convert or exchange such convertible or
                    exchangeable securities, if the Conversion Price shall have
                    been adjusted upon such becoming exercisable, convertible or
                    exchangeable, such Conversion Price shall forthwith be
                    readjusted to such Conversion Price as would have been
                    obtained had an adjustment been made upon such options,
                    warrants or other rights becoming exercisable or securities
                    becoming convertible or exchangeable on the basis of the
                    issuance of only the number of shares of Common Stock
                    actually issued upon the exercise of such options, warrants
                    or other rights, or upon the conversion or exchange of such
                    securities; and

                         (5) if the Conversion Price shall have been adjusted
                    upon such options, warrants or other rights becoming
                    exercisable or such convertible or exchangeable securities
                    becoming convertible or exchangeable, no further adjustment
                    of the Conversion Price shall be made for the actual
                    issuance of Common Stock upon the exercise, conversion or
                    exchange thereof.

               (ii) Excluded Shares. "Excluded Shares" has the meaning given to
          it in Article 4, Section C. 4(f)(ii) of this Amended and Restated
          Certificate of Incorporation.

               (iii) Stock Dividends; Stock Splits, Etc. If the number of shares
          of Common Stock outstanding at any time after the date of issuance of
          the Class D Preferred is increased by a stock dividend payable in
          Common Stock or by a subdivision or split-up of Common Stock, then
          immediately after the record date fixed for the determination of
          holders of Common Stock entitled to receive such stock dividend or the
          effective date of such subdivision or split-up, as the case may be,
          the Conversion Price shall be appropriately adjusted so that the
          holder of any Class D Preferred thereafter converted shall be entitled
          to receive the number of shares of Common Stock of the Corporation
          which such holder would have owned immediately following such action
          had such Class D Preferred been converted immediately prior thereto.

               (iv) Combination of Shares. If the number of shares of Common
          Stock outstanding at any time after the date of issuance of the Class
          D Preferred is decreased by a combination of the outstanding Common
          Stock, then immediately after the effective date of such combination,
          the Conversion Price shall be appropriately increased so that the
          holder of any Class D Preferred thereafter converted shall be entitled
          to receive the number of shares of Common Stock of the Corporation
          which such holder would have owned immediately following such action
          had such Class D Preferred been converted immediately prior thereto.



                                       54

   55



          (v) Reorganizations, Etc. In the case of any capital reorganization of
     the Corporation, any reclassification of Common Stock, the consolidation of
     the Corporation with or the merger of the Corporation with or into any
     other entity (other than a reorganization or merger solely for the purpose
     of the change in the state of incorporation of the Corporation) or the
     sale, lease or other transfer of all or substantially all of the assets of
     the Corporation to any other person or entity, each Class D Preferred shall
     after such capital reorganization, reclassification, consolidation, merger,
     sale, lease or other transfer be convertible into the number of shares of
     capital stock or other securities or property to which the Common Stock
     issuable (at the time of such capital reorganization, reclassification,
     consolidation, merger, sale, lease or other transfer) upon conversion of
     such Class D Preferred would have been entitled upon such capital
     reorganization, reclassification, consolidation, merger, sale, lease or
     other transfer; and in any such case, if necessary, the provisions set
     forth herein with respect to the rights and interests thereafter of the
     holders of the Class D Preferred shall be appropriately adjusted so as to
     be applicable, as nearly as may reasonably be possible, to any shares of
     capital stock or other securities or property thereafter deliverable on the
     conversion of the Class D Preferred. The subdivision or combination of
     Common Stock issuable upon conversion of Class D Preferred at any time
     outstanding into a greater or lesser number of shares of Common Stock
     (whether with or without par value) shall not be deemed to be a
     reclassification of the Common Stock of the Corporation for the purposes of
     this Section 4(f)(v).

          (vi) Evidences of Indebtedness or Assets. In case the Corporation
     shall declare a distribution payable in securities of other Persons,
     evidences of indebtedness issued by the Corporation or other Persons or
     assets (excluding cash dividends or dividends payable solely in Common
     Stock) then, in each such case, each holder of Class D Preferred shall be
     entitled to receive a proportionate share of any such distribution as if it
     had converted into the number of shares of Common Stock of the Corporation
     into which its Class D Preferred would have been convertible as of the
     record date fixed for the determination of the holders of outstanding
     shares of Common Stock of the Corporation entitled to receive such
     distribution.

          (vii) Rounding of Calculations; Minimum Adjustment. All calculations
     under this Section 4(f) shall be made to the nearest cent or to the nearest
     one-hundredth (1/100th) of a share, as the case may be. Any provision of
     this Section 4 to the contrary notwithstanding, no adjustment in the
     Conversion Price shall be made if the amount of such adjustment would be
     less than one cent ($0.01), but any such amount shall be carried forward
     and an adjustment with respect thereto shall be made at the time of, and
     together with, any subsequent adjustment which, together with such amount
     and any other amount or amounts so carried forward, shall aggregate one
     cent ($0.01) or more.

          (viii) Timing of Issuance of Additional Common Shares Upon Certain
     Adjustments. In any case in which the provisions of this Section 4(f) shall
     require that an adjustment shall become effective immediately after the
     record date for an event, the Corporation may defer until the occurrence of
     such event the issuing to


                                       55

   56



     the holder of any Class D Preferred converted after such record date and
     before the occurrence of such event the Additional Common Shares issuable
     upon such conversion by reason of the adjustment required by such event
     over and above the Common Stock issuable upon such conversion before giving
     effect to such adjustment; provided, that the Corporation upon request
     shall deliver to such holder a due bill or other appropriate instrument
     evidencing such holder's right to receive such additional shares upon the
     occurrence of the event requiring such adjustment.

          (ix) Applicable Adjustment. In any case in which the provisions of
     this Section 4(f) shall require an adjustment to the Conversion Price for
     the Class D Preferred, the applicable adjustment shall be the largest
     adjustment lowering the Conversion Price resulting from the application of
     any appropriate provision of this Section 4(f) to such event.

     (g) Current Market Price. "Current Market Price" shall have the meaning
given in Article 4, Section C. 4.(g) of this Amended and Restated Certificate of
Incorporation; provided, that, if within fifteen (15) days of receiving notice
of an event under Section 4(f) requiring the calculation of the Current Market
Price a holder of at least ten percent (10%) of the currently outstanding Class
D Preferred requests the appointment of an independent appraiser, the Board of
Directors shall, within ten (10) days of such request, appoint as an independent
appraiser a nationally-known independent public accounting firm or investment
bank and the Board of Directors shall direct such independent appraiser to
conduct an appraisal and make a report on the Current Market Price of a Share of
Common Stock within thirty (30) days of its appointment. The determination of
Current Market Price by such independent appraiser shall be final and binding
upon the Corporation and the holders of Class D Preferred. The costs of such
independent appraiser shall be paid by the Corporation. Any independent
appraiser so utilized shall agree to treat all information supplied by the
Corporation in a confidential manner.

     (h) Statement Regarding Adjustments. Whenever the Conversion Price is
adjusted as herein provided:

          (i) the Corporation shall compute the adjusted Conversion Price in
     accordance with this Section 4 and shall prepare a certificate signed by
     the Treasurer of the Corporation setting forth the adjusted Conversion
     Price and the facts requiring such adjustment, and such certificate shall
     forthwith be filed at the office of the transfer agent or agents, if any,
     for the Class D Preferred and at the principal office of the Corporation;
     and

          (ii) a notice stating that the Conversion Price has been adjusted and
     setting forth the adjusted Conversion Price and the facts requiring such
     adjustment shall, as soon as practicable, be mailed to the holders of
     record of the outstanding Class D Preferred. Where appropriate, such notice
     may be given in advance and may be included as part of a notice required to
     be mailed under the provisions of this Section 4(j).



                                       56

   57



     (i) Cancellation. All Class D Preferred which shall have been surrendered
for conversion as herein provided in this Section 4 shall no longer be deemed to
be outstanding and all rights with respect to such Class D Preferred, including
the rights, if any, to receive notices and to vote, shall forthwith cease and
terminate, except only the right of the holders thereof to receive Common Stock
or other assets or property in exchange therefor.

     (j) Notice to Holders. In the event that:

          (a) the Corporation shall take action to make any distribution or
     dividend to the holders of any class of its capital stock;

          (b) the Corporation shall take action to offer for subscription pro
     rata to the holders of any class of its capital stock securities of any
     kind;

          (c) the Corporation shall take action to accomplish any capital
     reorganization, or reclassification of the capital stock of the Corporation
     (other than a subdivision, split-up or combination of its Common Stock), or
     consolidation or merger to which the Corporation is a party and for which
     approval of any stockholders of the Corporation is required, or the sale or
     transfer of all or substantially all of the assets of the Corporation; or

          (d) the Corporation shall take action looking to a voluntary or
     involuntary dissolution, liquidation or winding up of the affairs of the
     Corporation;

then the Corporation shall (x) in case of any such distribution, dividend or
offering of subscription rights, at least ten (10) days prior to the date or
expected date on which the books of the Corporation shall close or a record
shall be taken for the determination of holders entitled to such distribution or
subscription rights, and (y) in the case of any such reorganization,
reclassification, consolidation, merger, sale, transfer, dissolution,
liquidation or winding up, at least ten (10) days prior to the date or expected
date when the same shall take place, cause written notice thereof to be mailed
to each holder of Class D Preferred at such holder's address as shown on the
books of the Corporation. The notice to be given in accordance with this Section
4(j) shall also specify (x) the date or expected date on which the holders of
any class of the Corporation's capital stock shall be entitled thereto, and (y)
the date or expected date on which the holders of any class of the Corporation's
capital stock shall be entitled to exchange their shares for securities or other
property deliverable upon such reorganization, reclassification, consolidation,
merger, sale, transfer, dissolution, liquidation or winding up, as the case may
be.

     (k) Reservation of Shares. The Corporation shall at all times reserve and
keep available, free from preemptive rights, out of its treasury shares or its
authorized but unissued Common Stock, for the purpose of effecting the
conversion of the Class D Preferred, the full number of shares of Common Stock
then deliverable upon the conversion of all Class D Preferred then outstanding.



                                       57

   58



     (l) Reclassification of Common Stock. For the purposes of this Section 4,
the term "Common Stock" shall mean (a) the class of stock designated as the
Common Stock of the Corporation on the date this Amended and Restated
Certificate of Incorporation is filed with the Secretary of State of Delaware,
or (b) any other class of stock resulting from successive changes or
reclassifications of such Common Stock consisting solely of changes in par value
or from no par value to par value, or from par value to no par value. If at any
time as a result of an adjustment made pursuant to the provisions of Section
4(f)(v), the holder of any Class D Preferred thereafter surrendered for
conversion shall become entitled to receive any shares of the Corporation other
than Common Stock, and the number of such other shares so receivable upon
conversion of any Class D Preferred shall be subject to adjustment from time to
time in a manner and on terms as nearly equivalent as practicable to the
provisions with respect to the Common Stock contained in Section 4(f)(v), and
the other provisions of this Section 4 with respect to the Common Stock shall
apply on like terms to any such other shares.

     (m) Treasury Shares. For the purpose of this Section 4, the sale or other
disposition of any Common Stock of the Corporation theretofore held in its
treasury shall be deemed to be an issuance thereof.

     (n) Approvals. If any Common Stock to be reserved for the purpose of
conversion of Class D Preferred requires registration with or approval of any
governmental authority under any Federal or state law or of the NASDAQ System
before such shares may be validly issued or delivered upon conversion, the
Corporation will in good faith and as expeditiously as possible secure such
registration or approval, as the case may be. If, and so long as, any Common
Stock into which the Class D Preferred are then convertible are listed on any
national securities exchange, the Corporation will, if permitted by the rules of
such exchange, list and keep listed on such exchange, upon official notice of
issuance, all of such Common Stock issuable upon conversion.

     (o) Valid Issuance. All Common Stock that may be issued upon conversion of
the Class D Preferred will upon issuance by the Corporation be duly and validly
issued, fully paid and nonassessable and free from all taxes, liens and charges
with respect to the issuance thereof, and the Corporation shall take no action
which will cause a contrary result (including, without limitation, any action
which would cause the Conversion Price to be less than the par value, if any, of
the Common Stock).

G.  TERMS OF CLASS E CONVERTIBLE EXCHANGEABLE PREFERRED STOCK

     The following is a statement of the express terms, powers, preferences,
rights, qualifications, limitations and restrictions in respect of the shares of
the Class E Preferred. Except as otherwise expressly provided in this Section G
of this Article Fourth ("Section G"), references to "Sections" in this Section G
shall be references to Sections within this Section G.

CLASS E CONVERTIBLE EXCHANGEABLE PREFERRED STOCK

     1. Voting Rights.

          (a) Except as expressly provided in Sections 1(b) and 1(c), holders of
     Class E Preferred shall not have any voting rights on any matter submitted
     to a vote of stockholders of the Corporation and shall not otherwise be
     entitled to vote together with holders of Common Stock, including with
     respect to the election of Directors of the Corporation.

          (b) Subject to the rights of any class of Preferred Stock that may
     from time to time come into existence, so long as any shares of Class E
     Preferred are outstanding, the Corporation shall not without first
     obtaining the approval of the holders of at least a majority of the
     then-outstanding shares of Class E Preferred, voting separately as a class:

               (i) other than as provided in Section 1(c), amend this Amended
          and Restated Certificate of Incorporation so as to affect adversely
          the shares of Class E Preferred or any holder thereof; or

               (ii) amend this Section G in any other respect.

          (c) So long as any shares of Class E Preferred are outstanding, the
     Corporation shall not without first obtaining the approval of the holders
     of at least a majority of the then-outstanding shares of Preferred Stock,
     voting together as a class on an As Converted Basis, authorize, issue or
     sell or obligate itself to authorize, issue or sell any class of its
     capital stock convertible into or exercisable for any equity security which
     ranks senior or pari passu in right, either as to voting, dividends or upon
     liquidation, with the Class E Preferred Shares.



                                       59

   60



     2.   Dividend Rights.

          (a) The Class E Preferred, for a period of six years from the date of
     first issuance of the Class E Preferred, shall be entitled a dividend equal
     to 7% per annum. Such dividend shall (i) be cumulative, (ii) compound on an
     annual basis, the first compounding to commence one year from the date of
     the first issuance of the Class E Preferred, (iii) be payable, at the
     option of the Corporation, at the time of conversion of the Class E
     Preferred pursuant to Section 4, (A) by the issuance of additional shares
     of Class E Preferred, at a price per share equal to the Original Issue
     Price thereof (as defined in this Section 2) or (B) in cash, (iv) be
     payable only upon conversion of the Class E Preferred, and (v) be canceled
     upon exchange of the Class E Preferred pursuant to Section 5. The "Original
     Issue Price" per share of Class E Preferred equals $1,000, as appropriately
     adjusted for any stock split, stock dividend paid in Class E Preferred or
     subdivision or split up of such shares. Fractional shares of Class E
     Preferred shall be issuable for purposes of this Section 2(a).

          (b) In addition to the dividends provided for in Section 2(a), the
     holders of outstanding Class E Preferred shall be entitled to receive,
     when, as and if declared by the Board of Directors from funds legally
     available therefor, a portion of any dividends declared on Common Stock in
     the same form as such Common Stock dividends; provided, that for the
     purposes of determining the amount of any such dividend payable to the
     holders of Class E Preferred, such holders shall be entitled to receive a
     proportionate amount of such dividends as if all issued and outstanding
     Class E Preferred had been converted into Common Stock as of the record
     date for the determination of holders entitled to receive said dividend. In
     the event of an IPO, the Corporation may, at its option, pay any accrued
     and unpaid dividends in Common Stock, which Common Stock shall be valued
     for this purpose at the price per share paid by the public.

     3.   Liquidation Rights.

          (a) Upon the dissolution, liquidation or winding up of the affairs of
     the Corporation, whether voluntary or involuntary, or the sale, conveyance,
     exchange or transfer (for cash, shares of stock, securities or other
     consideration) of all or substantially all the property and assets of the
     Corporation, or the reorganization, consolidation or merger of the
     Corporation with or into any other company or companies, or a transaction
     or series of related transactions in which more than fifty percent (50%) of
     the voting power of the Corporation is disposed of or sold (whether by the
     Corporation or the holders of outstanding capital stock), the holders of
     outstanding Preferred Stock and Common Stock will be entitled to receive
     from the Corporation's assets available for distribution to stockholders,
     the amounts and preferences as set forth below:


               (i) The holders of Class F Preferred shall receive cash in the
          amount of Twelve Dollars ($12.00) per share, plus an amount equal to
          all declared but unpaid dividends on such shares, before any payment
          or


                                       60

     of the remaining assets of the Corporation.

     4. Conversion Rights. The holders of the Class E Preferred shall have
conversion rights, through and including the Conversion Termination Date (as
defined in Section 6(a)), as follows (the "Conversion Rights"):

          (a) Conversion.

               (i) The Class E Preferred shall be convertible in whole, but not
          in part, in accordance with this Section 4(a), at the option of the
          holders thereof, at any time after the third anniversary of the date
          of issuance and prior to the Conversion Termination Date at the office
          of the Corporation or any transfer agent for such stock, into such
          number of fully paid and non-assessable shares of Common Stock as is
          determined by dividing (x) the sum of the Original Issue Price and all
          accrued and unpaid dividends thereon by (y) $19.80 (such quotient, the
          "Conversion Price"); provided, however, that the Conversion Price for
          the Class E Preferred shall be subject to adjustment as set forth in
          Section 4(a)(iii).

               (ii) Before the holders of Class E Preferred shall be entitled to
          convert such shares into shares of Common Stock, such holders shall
          surrender the certificate or certificates therefor, duly endorsed, at
          the office of the Corporation or of any transfer agent for the Class E
          Preferred, and shall give written notice to the Corporation at its
          principal corporate office, of the election to convert the same and
          shall state therein the name or names in which the certificate or
          certificates for shares of Common Stock are to be issued. The
          Corporation shall, as soon as practicable thereafter, issue and
          deliver at such office to such holders of Class E Preferred, or to the
          nominee or nominees of such holders, a certificate or certificates for
          the number of shares of Common Stock to which such holders shall be
          entitled as set forth above. Such conversion shall be deemed to have
          been made immediately prior to the close of business on the date of
          such surrender of the shares of Class E Preferred to be converted, 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 as of such
          date. The Corporation shall not be required to pay any tax which may
          be payable with respect to any transfer involved in the issue


                                       63

   64



          and delivery of any certificate in a name other than that of the
          holder of the Class E Preferred and the Corporation shall not be
          required to issue or deliver any such certificate unless and until the
          person requesting the issue thereof shall have paid to the Corporation
          the amount of such tax or has established to the satisfaction of the
          Corporation that such tax has been paid.

               (iii) In the event the Corporation should at any time fix a
          record date for the effectuation of a split or subdivision of the
          outstanding shares of Common Stock or the determination of holders of
          Common Stock entitled to receive a dividend or other distribution
          payable in additional shares of Common Stock or other securities or
          rights convertible into, or entitling the holder thereof to receive
          directly or indirectly, additional shares of Common Stock (hereinafter
          referred to as "Common Stock Equivalents") without payment of any
          consideration by such holder for the additional shares of Common Stock
          or the Common Stock Equivalents (including the additional shares of
          Common Stock issuable upon conversion or exercise thereof) then, as of
          such record date (or the date of such dividend distribution, split or
          subdivision if no record date is fixed), the Conversion Price of the
          Class E Preferred shall be appropriately decreased so that the number
          of shares of Common Stock issuable on conversion of each share of such
          class shall be increased in proportion to such increase of the
          aggregate of (a) shares of Common Stock outstanding and (b) those
          issuable with respect to such Common Stock Equivalents, with the
          number of shares issuable with respect to Common Stock Equivalents
          determined from time to time as provided in Section 4(a)(v).

               (iv) If the number of shares of Common Stock outstanding at any
          time is decreased by a combination of the outstanding shares of Common
          Stock, then, following the record date of such combination, the
          Conversion Price for the Class E Preferred shall be appropriately
          increased so that the number of shares of Common Stock issuable on
          conversion of each share of such class shall be decreased in
          proportion to such decrease in outstanding shares.

               (v) The following provisions shall apply for purposes of this
          Section 4(a):


                    (A) The aggregate maximum number of shares of Common Stock
               deliverable upon conversion or exercise of Common Stock
               Equivalents (assuming the satisfaction of any conditions to
               convertibility or exercisability, including, without limitation,
               the passage of time, but without taking into account potential
               antidilution adjustments) shall be deemed to have been issued at
               the time such Common Stock Equivalents were issued.



                                       64

   65



                    (B) In the event of any change in the number of shares of
               Common Stock deliverable or in the consideration payable to the
               Corporation upon conversion or exercise of such Common Stock
               Equivalents including, but not limited to, a change resulting
               from the antidilution provisions thereof, the Conversion Price of
               the Class E Preferred Stock, to the extent in any way affected by
               or computed using such Common Stock Equivalents, shall be
               recomputed to reflect such change, but no further adjustment
               shall be made for the actual issuance of Common Stock or any
               payment of such consideration upon the exercise of any such
               options or rights or the conversion or exchange of such
               securities.

                    (C) Upon the termination or expiration of the convertibility
               or exercisability of any such Common Stock Equivalents, the
               Conversion Price of the Class E Preferred Stock, to the extent in
               any way affected by or computed using such Common Stock
               Equivalents, shall be recomputed to reflect the issuance of only
               the number of shares of Common Stock (and Common Stock
               Equivalents which remain convertible or exercisable) actually
               issued upon the conversion or exercise of such Common Stock
               Equivalents.

          (b) Automatic Conversion. The Class E Preferred shall automatically be
     converted into shares of Common Stock at the Conversion Price upon the
     earliest to occur prior to the Conversion Termination Date of: the time
     immediately prior to the effective time of (x) the acquisition of the
     Corporation by another entity by means of any transaction or series of
     related transactions (including, without limitation, any reorganization,
     merger or consolidation in which the Corporation is not the surviving
     entity, but excluding any merger effected exclusively for the purpose of
     changing the domicile of the Corporation); (y) the sale of all or
     substantially all of the assets of the Corporation, unless the
     Corporation's stockholders of record as constituted immediately prior to
     such acquisition or sale will, immediately after such acquisition or sale
     (by virtue of securities issued as consideration for the Corporation's
     acquisition or sale or otherwise) hold at least fifty percent (50%) of the
     voting power of the surviving entity in approximately the same relative
     percentages after such acquisition or sale as before such acquisition or
     sale; or (z) except as provided in Section 5(c), the initial public
     offering of Common Stock, provided, that the Corporation shall have given
     the holders of Class E Preferred notice that such event shall occur and
     that the Corporation desires the Class E Preferred to be converted.

     5.   Exchange Right.

          (a) Provided that (i) the Exchange Termination Date (as defined in
     Section 6(b)) shall not have occurred and (ii) Elan International Services,
     Ltd. ("EIS") and its affiliates are the holders of all of the shares of
     Class E Preferred (or, upon automatic conversion of such stock into shares
     of Common Stock, as set forth in Section 4(b)), such Common Stock
     (collectively, with the Class E Preferred, the "Exchange Shares")), the
     holders of the Exchange Shares (acting by act of the majority holders


                                       65

   66



     thereof) shall have the right, at any time after the second anniversary of
     the date of issuance of the Class E Preferred, to exchange all, but not
     less than all, of the Exchange Shares (the "Exchange Right") for the
     greater of (i) 4,510 fully paid and nonassessable shares of common stock,
     par value $1.00 per share ("Newco Common Stock"), of Athersys Newco, Ltd.
     ("Newco") (subject to adjustment for splits, stock dividends and similar
     events occurring in respect of Newco Common Stock) owned by the
     Corporation, or (ii) a number of shares of Newco Common Stock owned by the
     Corporation that, after giving effect to the exercise of the Exchange
     Right, would cause EIS and the Corporation to each hold 50% of the total
     outstanding share capital of Newco (assuming that neither EIS nor the
     Corporation has ever sold any shares of Newco and that Newco has not issued
     or sold any shares of Newco to any third party), provided, however, that if
     EIS or the Corporation has ever sold any shares of Newco, or Newco has
     issued or sold any shares of Newco, the provisions of clause (i) of this
     Section 5(a) shall apply; provided, that EIS may exercise the Exchange
     Right, prior to a date that is two years after the date of issuance of the
     Class E Preferred, pursuant to an automatic conversion, in which case (i)
     the shares of Newco stock to be transferred by the Corporation to EIS upon
     exercise of the Exchange Right shall be shares of non-voting convertible
     preferred stock of Newco of the same series as the preferred stock issued
     to EIS on October 21, 1999 (the "Newco Preferred Stock") and (ii) EIS and
     the Corporation shall cause Newco to convert an adequate number of shares
     of Newco Common Stock held by the Corporation into shares of Newco
     Preferred Stock for the purposes of effecting with the Exchange Right. The
     Newco Preferred Stock shall be convertible into common shares of Newco on a
     one-for-one basis, subject to adjustment for splits, stock dividends and
     similar events occurring in respect of Newco Common Stock, at any time
     after such two year period.

          (b) Upon exercise of the Exchange Right, the Exchange Shares,
     including all accrued and unpaid dividends thereon, shall be canceled and
     shall no longer be entitled to any rights in the Corporation.

          (c) The Exchange Shares shall be exchangeable for Newco Common Stock,
     in whole, but not in part, in accordance with this Section 5, at any time
     after the second anniversary of the date of issuance of the Class E
     Preferred and prior to the Exchange Termination Date (as defined in Section
     6(b)); provided, that the Exchange Right may be exercised (at the
     discretion of EIS) prior to such two-year period in the event of (i) any
     public offering of securities of the Company or Newco; (ii) any material
     financing of Newco, including without limitation, the admission of
     additional equity or shareholders in Newco (or the equivalent, including as
     a result of the issuance of convertible, exchangeable or exercisable
     securities); (iii) any disposition or acquisition (including by way of
     license, sublicense or otherwise) of any material asset of Newco, (iv) any
     merger, consolidation, material asset sale or acquisition or similar
     transaction involving the Company or Newco or (v) any material change in
     the business plan or lines of business of Newco. If the Class E Preferred
     is converted pursuant to Section 4(a), to shares of Common Stock, the
     Exchange Right with respect to all shares of Class E Preferred shall be
     terminated and of no further force and effect.

          (d) In order to exercise the Exchange Right, the holders of the
     Exchange Shares shall provide written notice thereof to the Corporation,
     setting forth (i) the fact that such holders intend to exercise the
     Exchange Right, and (ii) the proposed date for


                                       66

   67



     such exercise (the "Exchange Date"), which shall be between 10 and 30 days
     after the date of such notice, provided, however, that if the Corporation
     shall deliver the holders of the Exchange Shares a written request to delay
     the date for such exercise by no more than 45 days, the Exchange Date will
     be as set forth in that request. During the period after the receipt of
     such written request, and before the Exchange Date, the holders of the
     Exchange Shares shall negotiate with the Corporation in good faith an
     alternative mechanism for the transfer of the Newco Common Stock that will
     reduce the Corporation's tax liability, provided that the holders of the
     Exchange Shares shall not be required to agree to any transaction which is
     financially disadvantageous to them. On the Exchange Date, (x) the holders
     shall tender their shares of the Exchange Shares to the Corporation for
     cancellation, and (y) the Corporation shall cause Newco to deliver to EIS,
     acting on behalf of such holders, such shares of Newco Common Stock. The
     holders of the Exchange Shares and the Corporation shall take all other
     necessary or appropriate actions in connection with or to effect such
     closing.

          6.   Termination Date.

          (a) The rights of the holders to convert the Class E Preferred into
     shares of Common Stock pursuant to Section 4 shall terminate and be of no
     further force and effect on the date that is six years after the date of
     the first issuance of any shares of Class E Preferred hereunder (the
     "Conversion Termination Date").

          (b) The rights of the holders to exercise the Exchange Right pursuant
     to Section 5 shall terminate and be of no further force and effect on the
     earlier to occur of (i) the date that is six years after the date of the
     first issuance of any shares of the Class E Preferred hereunder and (ii)
     the date on which Newco (as defined in the Purchase Agreement) shall
     complete an initial public offering of its common equity (the "Exchange
     Termination Date").

     7. Recapitalizations. On or prior to the Conversion Termination Date, if at
any time or from time to time there shall be a recapitalization of the Common
Stock (other than a subdivision, combination or merger or sale of assets
provided for in Section 3 or Section 4) provision shall be made so that the
holders of the Class E Preferred shall thereafter be entitled to receive upon
conversion of the Class E Preferred the number of shares of stock or other
securities or property of the Corporation or otherwise, to which a holder of
Common Stock deliverable upon conversion would have been entitled on such
recapitalization. In any such case, appropriate adjustment shall be made in the
application of the provisions of Section 4 with respect to the rights of the
holders of the Class E Preferred after the recapitalization to the end that the
provisions of Section 4 (including adjustment of the Conversion Price then in
effect and the number of shares purchasable upon conversion of the Class E
Preferred) shall be applicable after that event as nearly equivalent as may be
practicable.

     8. No Impairment. The Corporation will not, by amendment of its Certificate
of Incorporation or through any reorganization, recapitalization, transfer of
assets, consolidation, merger, dissolution, issuance or sale of securities or
any other voluntary action, avoid or seek to avoid the observance or performance
of any of the terms to be observed or performed hereunder by the Corporation,
but will at all times in good faith assist in the carrying out of all the
provisions hereof and in the taking of all such action as may be necessary or
appropriate in order


                                       67

   68



to protect the Class E Conversion Rights and Exchange Right of the holders of
the Class E Preferred against impairment.

     9. Fractional Shares and Certificate as to Adjustments.

          (a) No fractional shares shall be issued upon the conversion of the
     Class E Preferred, and the number of shares of Common Stock to be issued
     shall be rounded to the nearest whole share.

          (b) Upon the occurrence of each adjustment or readjustment of the
     Conversion Price pursuant to Section 4, the Corporation, at its expense,
     shall promptly compute such adjustment or readjustment in accordance with
     the terms hereof and prepare and furnish to each holder of shares of Class
     E Preferred a certificate setting forth such adjustment or readjustment and
     showing in detail the facts upon which such adjustment or readjustment is
     based. The Corporation shall, upon the written request at any time of any
     holder of Class E Preferred, furnish or cause to be furnished to such
     holder a like certificate setting forth (i) such adjustment and
     readjustment, (ii) the Conversion Price at the time in effect, and (iii)
     the number of shares of Common Stock and the amount, if any, of other
     property which at the time would be received upon the conversion of a share
     of Class E Preferred.

     10. Notices. Any notice required by the provisions hereof to be given to
the holders of shares of Class E Preferred shall be deemed given on the date of
service if served personally on the party to whom notice is to be given, or on
the date of transmittal of services by facsimile transmission to the party to
whom notice is to be given, and addressed to each holder of record at his or its
address appearing on the books of the Corporation.

     each holder of Class F Preferred shall be entitled to cast the number of
     votes which he or it would have had the right to cast had all of its or his
     Class F Preferred been converted, as provided in Section 4, into Common
     Stock ("As Converted Basis") as of the record date of the meeting at which
     such votes are to be cast or as of the date any written consent is taken,

     outstanding Class F Preferred, voting as a single class on an As Converted
     Basis, and such further affirmative vote, if any, of the holders of any

     provided, that for the purposes of determining the amount of any such
     dividend payable to the holders of Class F Preferred, such holders shall be
     entitled to receive a proportionate amount of such dividends as if all
     issued and outstanding Class F Preferred had been converted into Common

          the aggregate amount payable to the holders of the Common Stock

          shall share ratably in any distribution of assets in proportion to the
          full amounts to which they would otherwise be respectively entitled.
          Further, in the event that the holders of the Class F Preferred shall

          Corporation has insufficient funds to pay the amounts payable under

          shall share ratably in any distribution of assets in proportion to the
          full amounts to which they would otherwise be respectively entitled.

               (b) None of the sale, conveyance, exchange or transfer (for cash,
          shares of stock, securities or other consideration) of all or
          substantially all the property and assets of the Corporation, nor the

          the reorganization of the Corporation, shall be deemed a liquidation,
          dissolution or winding up of the affairs of the Corporation within the
          meaning of this Section 3 if the holders of at least fifty-one percent
          (51%) of the then outstanding Convertible Preferred Shares and Class F
          Preferred together elect to have such events not deemed a liquidation
          of the Corporation by giving written notice to the Corporation.

               (c) After the payment in cash to the holders of Class F Preferred

          effect and the holders of such Common Stock shall share all of the
          assets of the Corporation available for distribution to all holders of
          Common Stock ratably in proportion to the number of shares of Common
          Stock held by them respectively.

          4.   Conversion Rights.

               (a) Conversion. The holder of each outstanding Class F Preferred
          shall, subject to the terms and conditions hereinafter set forth,
          convert such Class F Preferred into fully paid and nonassessable
          shares of Common Stock at the Conversion Price (as defined in Section
          4(b)) in effect on the Conversion Date (as defined in Section 4(c)),
          at the following times and pursuant to the following conditions: (i)
          at any time, at such


                                       73

   74



         stockholder's option; (ii) automatically and simultaneously upon the
         Closing of a Public Offering (as defined in this Section 4(a)); or
         (iii) upon the written notice to the Corporation at the election by the
         holders of seventy-five percent (75%) of the outstanding Class F
         Preferred, voting on an As Converted Basis. The Closing of a Public
         Offering, for purposes of this Section H. 4 only, shall mean the
         Closing of the sale by the Corporation of Common Stock pursuant to an
         effective registration statement under the Securities Act of 1933, as
         amended; provided, that such sale yields gross proceeds of not less
         than Fifty Million Dollars ($50,000,000) at a price of not less than
         Fifteen Dollars ($15.00) per share and is made pursuant to a firm
         commitment underwriting.

               (b) Conversion Price. Each Class F Preferred shall be convertible
          at an office or agency referred to below into a number of fully paid
          and nonassessable shares of Common Stock (calculated as to each
          conversion to the nearest one-hundredth (1/100th) of a share) as is
          determined by dividing Twelve Dollars ($12.00) by the Conversion Price
          in effect on the Conversion Date. As of the date this Amended and
          Restated Certificate of Incorporation was filed with the Secretary of
          State of Delaware, the price at which Common Stock shall initially be
          issuable upon conversion shall be Twelve Dollars ($12.00) per share,
          which price may be adjusted from time to time as provided in Section
          4(f) (the "Conversion Price").

               (c) Method of Conversion. In order to exercise such conversion
          privilege, the holder of any Class F Preferred to be converted shall
          present and surrender the certificate(s) representing such Class F
          Preferred during usual business hours at any office or agency of the
          Corporation maintained for the transfer of Class F Preferred and shall
          deliver a written notice of its election to convert the Class F
          Preferred represented by such certificate(s), or any portion thereof,
          specified in such notice. Such notice shall also state the name or
          names (with address) in which the certificate or certificates for
          Common Stock issuable on such conversion shall be issued. If so
          required by the Corporation, any certificate for Class F Preferred
          surrendered for conversion shall be accompanied by instruments of
          transfer, in form satisfactory to the Corporation, duly executed by
          the holder of such Class F Preferred or such holder's duly authorized
          representative. Each conversion of Class F Preferred shall be deemed
          to have been effected on the date (the "Conversion Date") on which the
          certificate or certificates representing such Class F Preferred shall
          have been surrendered and any required notice and instruments of
          transfer received as aforesaid. Subject to the provisions of Section
          4(f)(viii), the person or persons in whose name or names any
          certificate or certificates for Common Stock shall be issuable upon
          such conversion shall be deemed to have become the holder or holders
          of record of such Common Stock immediately prior to the close of
          business on the Conversion Date. Subject to the provisions of Section
          (f)(viii), as promptly as practicable (and in any event within two (2)
          business days) after the presentation and surrender for conversion, as
          herein provided, of any certificate or certificates for Class F
          Preferred, the Corporation shall issue and deliver at such office or
          agency, to or upon the written order of the holder thereof, a
          certificate or certificates for the number of shares of Common Stock
          issuable upon such conversion. In case any certificate or certificates
          for Class F Preferred shall be surrendered for conversion of less than
          all of the Class F Preferred represented thereby, the Corporation
          shall deliver at such office or agency, to or upon the written order
          of the holder thereof, a certificate or certificates for the number of
          Class F Preferred represented by such surrendered


                                       74

   75



          certificate or certificates which are not converted. The issuance of
          certificates for Common Stock issuable upon the conversion of Class F
          Preferred, and the issuance of certificates representing Class F
          Preferred which are not converted as described above, shall be at the
          Corporation's expense and without charge to the converting holder for
          any tax imposed on the Corporation in respect of the issue thereof.
          The Corporation shall not, however, be required to pay any tax which
          may be payable with respect to any transfer involved in the issue and
          delivery of any certificate in a name other than that of the holder of
          the Class F Preferred and the Corporation shall not be required to
          issue or deliver any such certificate unless and until the person
          requesting the issue thereof shall have paid to the Corporation the
          amount of such tax or has established to the satisfaction of the
          Corporation that such tax has been paid.

               (d) No Adjustment for Dividends. With respect to any conversion
          of Class F Preferred into Common Stock pursuant to this Section 4, no
          adjustment shall be made for dividends declared but as yet unpaid on
          the Class F Preferred as of any record date prior to the Conversion
          Date; provided, however, that upon the conversion of such Class F
          Preferred, the dividend declared but as yet unpaid on the Class F
          Preferred shall be payable on the Common Stock issued upon such
          conversion as if such Common Stock were outstanding as of the record
          date for the determination of holders entitled to receive said
          dividend.

               (e) Fractional Shares. If more than one Class F Preferred share
          shall be surrendered for conversion at one time by the same holder,
          the number of full shares of Common Stock issuable upon conversion
          thereof shall be computed on the basis of the aggregate number of
          Class F Preferred shares so surrendered. If any fractional interest in
          a Share of Common Stock would be deliverable upon the conversion of
          any Class F Preferred, the Corporation shall issue a certificate which
          shall evidence and include such fractional interest in the Common
          Stock.

               (f) Conversion Price Adjustments. The Conversion Price for the
          Class F Preferred shall be subject to adjustment from time to time as
          follows:

                    (i) Common Stock Issued at Less Than the Conversion Price.
               In the event that the Corporation shall issue Additional Common
               Shares (as defined in Article 4, Section C. 4(f)(i) of this
               Amended and Restated Certificate of Incorporation), the
               Conversion Price in effect immediately prior to each such
               issuance shall forthwith be reduced to a price determined by
               multiplying the then current Conversion Price by a fraction (A)
               the numerator of which shall be the sum of (1) the number of
               shares of Common Stock outstanding immediately prior to such
               issuance, plus (2) the number of shares of Common Stock that the
               aggregate consideration received by the Corporation for the total
               number of Additional Common Shares so issued would purchase at
               such Conversion Price, and (B) the denominator of which shall be
               the number of shares of Common Stock outstanding immediately
               prior to such issuance plus the number of Additional Common
               Shares so issued.

               For the purposes of any adjustment of the Conversion Price
          pursuant to this Section 4(f)(i), the following provisions shall be
          applicable:


                                       75

   76



                    (A) Cash. In the case of the issuance of Common Stock for
               cash, the amount of the consideration received by the Corporation
               shall be deemed to be the amount of the cash proceeds received by
               the Corporation for such Common Stock before deducting therefrom
               any reasonable discounts, commissions, taxes or other expenses
               allowed, paid or incurred by the Corporation for any underwriting
               or otherwise in connection with the issuance and sale thereof.

                    (B) Consideration Other Than Cash. In the case of the
               issuance of Common Stock (other than upon the conversion of
               shares of capital stock or other securities of the Corporation)
               for a consideration in whole or in part other than cash,
               including securities acquired in exchange therefor (other than
               securities by their terms so exchangeable), the consideration
               other than cash shall be deemed to be the fair value thereof (as
               determined in good faith by the Board of Directors of the
               Corporation, whose determination shall be conclusive to the
               extent reasonable), irrespective of any accounting treatment;
               provided, that such fair value as determined by the Board of
               Directors shall not exceed the aggregate Current Market Price (as
               defined in Section 4(g)) of the Common Stock being issued as of
               the date the Board of Directors authorizes the issuance of such
               Common Stock.

                    (C) Options and Convertible Securities. In the case of the
               issuance of (i) options, warrants or other rights to purchase or
               acquire Common Stock (whether or not at the time exercisable)
               other than Excluded Shares, (ii) securities by their terms
               convertible into or exchangeable for Common Stock (whether or not
               at the time so convertible or exchangeable), or (iii) options,
               warrants or rights to purchase such convertible or exchangeable
               securities (whether or not at the time exercisable):

                         (1) the aggregate maximum number of shares of Common
                    Stock deliverable upon exercise of such options, warrants or
                    other rights to purchase or acquire Common Stock shall be
                    deemed to have been issued at the time such options,
                    warrants or other rights become exercisable and for a
                    consideration equal to the consideration (determined in the
                    manner provided in Sections 4(f)(i)(A) and (B)), if any,
                    received by the Corporation upon the issuance of such
                    options, warrants or other rights plus the minimum purchase
                    price provided in such options, warrants or other rights for
                    the Common Stock covered thereby;

                         (2) the aggregate maximum number of shares of Common
                    Stock deliverable upon conversion of or in exchange for any
                    such convertible or exchangeable securities, or upon the
                    exercise of options, warrants or other rights to purchase or
                    acquire such convertible or exchangeable securities and the
                    subsequent conversion or exchange thereof, shall be deemed
                    to have been


                                       76

   77



                    issued at the time such securities become convertible or
                    exchangeable or such options, warrants or other rights
                    become exercisable and for a consideration equal to the
                    consideration, if any, received by the Corporation for any
                    such securities and related options, warrants or other
                    rights (excluding any cash received on account of accrued
                    interest or accrued dividends), plus the additional
                    consideration, if any, to be received by the Corporation
                    upon the conversion or exchange of such securities and the
                    exercise of any related options, warrants or other rights
                    (the consideration in each case to be determined in the
                    manner provided in Sections 4(f)(i)(A) and (B));

                         (3) on any change in the number of shares of Common
                    Stock deliverable upon exercise of any such options,
                    warrants or other rights which have become exercisable or
                    conversion of or exchange of such convertible or
                    exchangeable securities which have become convertible or
                    exchangeable, or any change in the consideration to be
                    received by the Corporation upon such exercise, conversion
                    or exchange, including, but not limited to, a change
                    resulting from any subdivision, split-up, combination or
                    reclassification thereof, the Conversion Price as then in
                    effect shall forthwith be readjusted to such Conversion
                    Price as would have been obtained had an adjustment been
                    made upon such options, warrants or other rights not
                    exercised becoming exercisable prior to such change, or
                    securities not converted or exchanged becoming convertible
                    or exchangeable prior to such change, upon the basis of such
                    change but only if as a result of such adjustment the
                    Conversion Price then in effect is thereby reduced;

                         (4) on the expiration or cancellation of any such
                    options, warrants or other rights, or the termination of the
                    right to convert or exchange such convertible or
                    exchangeable securities, if the Conversion Price shall have
                    been adjusted upon such becoming exercisable, convertible or
                    exchangeable, such Conversion Price shall forthwith be
                    readjusted to such Conversion Price as would have been
                    obtained had an adjustment been made upon such options,
                    warrants or other rights becoming exercisable or securities
                    becoming convertible or exchangeable on the basis of the
                    issuance of only the number of shares of Common Stock
                    actually issued upon the exercise of such options, warrants
                    or other rights, or upon the conversion or exchange of such
                    securities; and

                         (5) if the Conversion Price shall have been adjusted
                    upon such options, warrants or other rights becoming
                    exercisable or such convertible or exchangeable securities
                    becoming convertible or exchangeable, no further adjustment
                    of the Conversion Price shall be made for the actual
                    issuance of Common Stock upon the exercise, conversion or
                    exchange thereof.


                                       77

   78



               (ii) Excluded Shares. "Excluded Shares" has the meaning given to
          it in Article 4, Section C. 4(f)(ii) of this Amended and Restated
          Certificate of Incorporation.

               (iii) Stock Dividends; Stock Splits, Etc. If the number of shares
          of Common Stock outstanding at any time after the date of issuance of
          the Class F Preferred is increased by a stock dividend payable in
          Common Stock or by a subdivision or split-up of Common Stock, then
          immediately after the record date fixed for the determination of
          holders of Common Stock entitled to receive such stock dividend or the
          effective date of such subdivision or split-up, as the case may be,
          the Conversion Price shall be appropriately adjusted so that the
          holder of any Class F Preferred thereafter converted shall be entitled
          to receive the number of shares of Common Stock of the Corporation
          which such holder would have owned immediately following such action
          had such Class F Preferred been converted immediately prior thereto.

               (iv) Combination of Shares. If the number of shares of Common
          Stock outstanding at any time after the date of issuance of the Class
          F Preferred is decreased by a combination of the outstanding Common
          Stock, then immediately after the effective date of such combination,
          the Conversion Price shall be appropriately increased so that the
          holder of any Class F Preferred thereafter converted shall be entitled
          to receive the number of shares of Common Stock of the Corporation
          which such holder would have owned immediately following such action
          had such Class F Preferred been converted immediately prior thereto.

               (v) Reorganizations, Etc. In the case of any capital
          reorganization of the Corporation, any reclassification of Common
          Stock, the consolidation of the Corporation with or the merger of the
          Corporation with or into any other entity (other than a reorganization
          or merger solely for the purpose of the change in the state of
          incorporation of the Corporation) or the sale, lease or other transfer
          of all or substantially all of the assets of the Corporation to any
          other person or entity, each Class F Preferred shall after such
          capital reorganization, reclassification, consolidation, merger, sale,
          lease or other transfer be convertible into the number of shares of
          capital stock or other securities or property to which the Common
          Stock issuable (at the time of such capital reorganization,
          reclassification, consolidation, merger, sale, lease or other
          transfer) upon conversion of such Class F Preferred would have been
          entitled upon such capital reorganization, reclassification,
          consolidation, merger, sale, lease or other transfer; and in any such
          case, if necessary, the provisions set forth herein with respect to
          the rights and interests thereafter of the holders of the Class F
          Preferred shall be appropriately adjusted so as to be applicable, as
          nearly as may reasonably be possible, to any shares of capital stock
          or other securities or property thereafter deliverable on the
          conversion of the Class F Preferred. The subdivision or combination of
          Common Stock issuable upon conversion of Class F Preferred at any time
          outstanding into a greater or lesser number of shares of Common Stock
          (whether with or without par value) shall not be deemed to be a
          reclassification of the Common Stock of the Corporation for the
          purposes of this Section 4(f)(v).



                                       78

   79



               (vi) Evidences of Indebtedness or Assets. In case the Corporation
          shall declare a distribution payable in securities of other Persons,
          evidences of indebtedness issued by the Corporation or other Persons
          or assets (excluding cash dividends or dividends payable solely in
          Common Stock) then, in each such case, each holder of Class F
          Preferred shall be entitled to receive a proportionate share of any
          such distribution as if it had converted into the number of shares of
          Common Stock of the Corporation into which its Class F Preferred would
          have been convertible as of the record date fixed for the
          determination of the holders of outstanding shares of Common Stock of
          the Corporation entitled to receive such distribution.

               (vii) Rounding of Calculations; Minimum Adjustment. All
          calculations under this Section 4(f) shall be made to the nearest cent
          or to the nearest one-hundredth (1/100th) of a share, as the case may
          be. Any provision of this Section 4 to the contrary notwithstanding,
          no adjustment in the Conversion Price shall be made if the amount of
          such adjustment would be less than one cent ($0.01), but any such
          amount shall be carried forward and an adjustment with respect thereto
          shall be made at the time of, and together with, any subsequent
          adjustment which, together with such amount and any other amount or
          amounts so carried forward, shall aggregate one cent ($0.01) or more.

               (viii) Timing of Issuance of Additional Common Shares Upon
          Certain Adjustments. In any case in which the provisions of this
          Section 4(f) shall require that an adjustment shall become effective
          immediately after the record date for an event, the Corporation may
          defer until the occurrence of such event the issuing to the holder of
          any Class F Preferred converted after such record date and before the
          occurrence of such event the Additional Common Shares issuable upon
          such conversion by reason of the adjustment required by such event
          over and above the Common Stock issuable upon such conversion before
          giving effect to such adjustment; provided, that the Corporation upon
          request shall deliver to such holder a due bill or other appropriate
          instrument evidencing such holder's right to receive such additional
          shares upon the occurrence of the event requiring such adjustment.

               (ix) Applicable Adjustment. In any case in which the provisions
          of this Section 4(f) shall require an adjustment to the Conversion
          Price for the Class F Preferred, the applicable adjustment shall be
          the largest adjustment lowering the Conversion Price resulting from
          the application of any appropriate provision of this Section 4(f) to
          such event.

          (g) Current Market Price. "Current Market Price" shall have the
     meaning given in Article 4, Section C. 4.(g) of this Amended and Restated
     Certificate of Incorporation; provided, that, if within fifteen (15) days
     of receiving notice of an event under Section 4(f) requiring the
     calculation of the Current Market Price a holder of at least ten percent
     (10%) of the currently outstanding Class F Preferred requests the
     appointment of an independent appraiser, the Board of Directors shall,
     within ten (10) days of such request, appoint as an independent appraiser a
     nationally-known independent public accounting firm or investment bank and
     the Board of Directors shall


                                       79

   80



     direct such independent appraiser to conduct an appraisal and make a report
     on the Current Market Price of a Share of Common Stock within thirty (30)
     days of its appointment. The determination of the Current Market Price by
     such independent appraiser shall be final and binding upon the Corporation
     and the holders of Class F Preferred. The costs of such independent
     appraiser shall be paid by the Corporation. Any independent appraiser so
     utilized shall agree to treat all information supplied by the Corporation
     in a confidential manner.

          (h) Statement Regarding Adjustments. Whenever the Conversion Price is
     adjusted as herein provided:

               (i) the Corporation shall compute the adjusted Conversion Price
          in accordance with this Section 4 and shall prepare a certificate
          signed by the Treasurer of the Corporation setting forth the adjusted
          Conversion Price and the facts requiring such adjustment, and such
          certificate shall forthwith be filed at the office of the transfer
          agent or agents, if any, for the Class F Preferred and at the
          principal office of the Corporation; and

               (ii) a notice stating that the Conversion Price has been adjusted
          and setting forth the adjusted Conversion Price and the facts
          requiring such adjustment shall, as soon as practicable, be mailed to
          the holders of record of the outstanding Class F Preferred. Where
          appropriate, such notice may be given in advance and may be included
          as part of a notice required to be mailed under the provisions of
          Section 4(j).

          (i) Cancellation. All Class F Preferred which shall have been
     surrendered for conversion as herein provided in this Section 4 shall no
     longer be deemed to be outstanding and all rights with respect to such
     Class F Preferred, including the rights, if any, to receive notices and to
     vote, shall forthwith cease and terminate, except only the right of the
     holders thereof to receive Common Stock or other assets or property in
     exchange therefor.

          (j) Notice to Holders. In the event that:

               (i) the Corporation shall take action to make any distribution or
          dividend to the holders of any class of its capital stock;

               (ii) the Corporation shall take action to offer for subscription
          pro rata to the holders of any class of its capital stock securities
          of any kind;

               (iii) the Corporation shall take action to accomplish any capital
          reorganization, or reclassification of the capital stock of the
          Corporation (other than a subdivision, split-up or combination of its
          Common Stock), or consolidation or merger to which the Corporation is
          a party and for which approval of any stockholders of the Corporation
          is required, or the sale or transfer of all or substantially all of
          the assets of the Corporation; or



                                       80

   81



               (iv) the Corporation shall take action looking to a voluntary or
          involuntary dissolution, liquidation or winding up of the affairs of
          the Corporation; then the Corporation shall (x) in case of any such
          distribution, dividend or offering of subscription rights, at least
          ten (10) days prior to the date or expected date on which the books of
          the Corporation shall close or a record shall be taken for the
          determination of holders entitled to such distribution or subscription
          rights, and (y) in the case of any such reorganization,
          reclassification, consolidation, merger, sale, transfer, dissolution,
          liquidation or winding up, at least ten (10) days prior to the date or
          expected date when the same shall take place, cause written notice
          thereof to be mailed to each holder of Class F Preferred at such
          holder's address as shown on the books of the Corporation. The notice
          to be given in accordance with this Section 4 (j) shall also specify
          (x) the date or expected date on which the holders of any class of the
          Corporation's capital stock shall be entitled thereto, and (y) the
          date or expected date on which the holders of any class of the
          Corporation's capital stock shall be entitled to exchange their shares
          for securities or other property deliverable upon such reorganization,
          reclassification, consolidation, merger, sale, transfer, dissolution,
          liquidation or winding up, as the case may be.

          (k) Reservation of Shares. The Corporation shall at all times reserve
     and keep available, free from preemptive rights, out of its treasury shares
     or its authorized but unissued Common Stock, for the purpose of effecting
     the conversion of the Class F Preferred, the full number of shares of
     Common Stock then deliverable upon the conversion of all Class F Preferred
     then outstanding.


          (l) Reclassification of Common Stock. For the purposes of this Section
     4, the term "Common Stock" shall mean (a) the class of stock designated as
     the Common Stock of the Corporation on the date this Amended and Restated
     Certificate of Incorporation is filed with the Secretary of State of
     Delaware, or (b) any other class of stock resulting from successive changes
     or reclassifications of such Common Stock consisting solely of changes in
     par value or from no par value to par value, or from par value to no par
     value. If at any time as a result of an adjustment made pursuant to the
     provisions of Section 4)(f)(v), the holder of any Class F Preferred
     thereafter surrendered for conversion shall become entitled to receive any
     shares of the Corporation other than Common Stock, and the number of such
     other shares so receivable upon conversion of any Class F Preferred shall
     be subject to adjustment from time to time in a manner and on terms as
     nearly equivalent as practicable to the provisions with respect to the
     Common Stock contained in Section 4(f)(v), and the other provisions of this
     Section 4 with respect to the Common Stock shall apply on like terms to any
     such other shares.

          (m) Treasury Shares. For the purpose of this Section 4, the sale or
     other disposition of any Common Stock of the Corporation theretofore held
     in its treasury shall be deemed to be an issuance thereof.

          (n) Approvals. If any Common Stock to be reserved for the purpose of
     conversion of Class F Preferred requires registration with or approval of
     any governmental authority under any Federal or state law or of the NASDAQ
     System before


                                       81

   82



     such shares may be validly issued or delivered upon conversion, the
     Corporation will in good faith and as expeditiously as possible secure such
     registration or approval, as the case may be. If, and so long as, any
     Common Stock into which the Class F Preferred are then convertible are
     listed on any national securities exchange, the Corporation will, if
     permitted by the rules of such exchange, list and keep listed on such
     exchange, upon official notice of issuance, all of such Common Stock
     issuable upon conversion.

          (o) Valid Issuance. All Common Stock that may be issued upon
     conversion of the Class F Preferred will upon issuance by the Corporation
     be duly and validly issued, fully paid and nonassessable and free from all
     taxes, liens and charges with respect to the issuance thereof, and the
     Corporation shall take no action which will cause a contrary result
     (including, without limitation, any action which would cause the Conversion
     Price to be less than the par value, if any, of the Common Stock).

               purposes of the Corporation; or

                    (H) changes the Corporation into a nonprofit corporation.

               (ii) authorize, issue or sell or obligate itself to authorize,
          issue or sell any class of its capital stock or other securities
          (including debt securities) convertible into or exercisable for any

          to voting, dividends or upon liquidation, with the Convertible
          Preferred Shares.

          (c) Notwithstanding anything herein to the contrary contained in
     Section 1(a) or (b), so long as any Group I Preferred Stock remains
     outstanding, the Corporation shall not, without the affirmative vote by the
     holders of at least seventy-five percent (75%) of the then outstanding
     Group I Preferred Stock on an As Converted Basis, effect (i) any sale,
     lease, assignment, transfer or other conveyance of all or substantially all
     of the assets or capital stock of the Corporation, (ii) any

     receive dividends at the rate of 8% per annum, payable when and if declared
     by the Board of Directors of the Corporation out of funds legally available
     therefor annually, prior and in preference to any declaration or payment of
     any dividend on the Common Stock, in


                                       84

   85

     holders of outstanding Class G Preferred shall be entitled to receive,

     available therefor, a portion of any dividends declared on Common Stock;
     provided, that for the purposes of determining the amount of any such
     dividend payable to the holders of Class G Preferred, such holders shall be
     entitled to receive a proportionate amount of such dividends as if all
     issued and outstanding Class G Preferred had been converted into Common
     Stock as of the record date for the determination of holders entitled to
     receive said dividend.

     3.   Liquidation Rights.

          provided in the next proviso, the aggregate amount payable to the
          holders of Class E Preferred pursuant to this Section 3(a)(ii) shall
          not exceed Five Million Dollars ($5,000,000); provided, further, that
          if the holders of Class E Preferred shall have purchased additional

          receive cash in the amount of One and 85/100 Dollars ($1.85) per

               (v) After payment to the holders of Preferred Stock of their

          holders of outstanding shares of Common Stock as of the date of this
          Amended and Restated Certificate of Incorporation was filed with the
          Secretary of State of the State of Delaware (not including Common
          Stock issued upon conversion of Preferred Stock) shall receive cash in
          the amount of the original amounts for which such Common Stock was
          issued, which will be distributed ratably in proportion to the number
          of shares of Common Stock held by such holder, but in no event shall
          the aggregate amount payable to the holders of the Common Stock
          pursuant to this Section 3(a)(v) exceed One Million One Hundred
          Thousand Dollars ($1,100,000);

               (vi) After payment to the holders of Preferred Stock and Common
          Stock (not including Common Stock issued upon conversion of Preferred
          Stock) of their liquidation preference as set forth in Sections
          3(a)(i)-(v), the Founders and holders of vested options to purchase
          Common Stock shall receive cash in an amount equal to their pro-rata
          portion (using the number of shares the vested option holder would
          have if the options had been exercised at the then current exercise
          price) of Two Million Dollars ($2,000,000);

               (vii) After the payments set forth in Sections 3(a)(i) - (vi),
          all remaining assets of the Corporation shall be distributed ratably
          to the holders of outstanding shares of Common Stock in proportion to
          the number of shares of Common Stock held by such holders.

          If, upon any such event, the Corporation has insufficient funds to pay
     the amounts payable under Section 3(a)(i) to the holders of all the
     outstanding Class F Preferred, the


                                       86

   87



     holders of Class F Preferred shall share ratably in any distribution of
     assets in proportion to the full amounts to which they would otherwise be
     respectively entitled. Further, in the event that the holders of the Class
     F Preferred shall have been paid all amounts payable under Section 3(a)(i)
     but the Corporation has insufficient funds to pay the amounts payable under
     Section 3(a)(ii) to the holders of all the outstanding Class C Preferred,
     the holders of Class C Preferred shall share ratably in any distribution of
     assets in proportion to the full amounts to which they would otherwise be

     assets in proportion to the full amounts to which they would otherwise be

          (b) None of the sale, conveyance, exchange or transfer (for cash,
     shares of stock, securities or other consideration) of all or substantially
     all the property and assets of the Corporation, nor the consolidation or
     merger of the Corporation with or into any other corporation or
     corporations, nor the consolidation or merger of any other corporation or
     corporations with or into the Corporation, nor the reorganization of the
     Corporation, shall be deemed a liquidation, dissolution or winding up of
     the affairs of the Corporation within the meaning of this Section 3 if the
     holders of at least fifty-one percent (51%) of the then outstanding
     Convertible Preferred Shares and Class F Preferred together elect to have
     such events not deemed a liquidation of the Corporation by giving written
     notice to the Corporation.

          (c) After the payment in cash to the holders of Class G Preferred of
     the full preferential amount fixed in accordance with the provisions of
     Section 3(a) with respect to the outstanding Class G Preferred, the holders
     of outstanding Class G Preferred as such will have no right or claim to any
     of the remaining assets of the Corporation.

          (d) In the event (i) the holders of the Class G Preferred vote to
     convert their shares of Class G Preferred into Common Stock immediately
     prior to or in connection with an event specified in Section 3(a) or (ii)
     any holder of Class G Preferred otherwise converts their shares of Class G
     Preferred into Common Stock in accordance with such holder's rights under
     Section 4, the priorities and preferences set forth in Section 3(a) shall
     be of no further effect and the holders of such Common Stock shall share
     all of the assets of the Corporation available for distribution to all
     holders of Common Stock ratably in proportion to the number of shares of
     Common Stock held by them respectively.

     4.   Conversion Rights.

          (a) Conversion. The holder of each outstanding Class G Preferred
     shall, subject to the terms and conditions hereinafter set forth, convert
     such Class G Preferred into fully paid and nonassessable shares of Common
     Stock at the Conversion Price (as defined in Section 4(b)) in effect on the
     Conversion Date (as defined in Section 4(c)), at the following times and
     pursuant to the following conditions: (i) at any time, at such
     stockholder's option; (ii) automatically and simultaneously upon the
     Closing of a Public Offering; or (iii) upon the written notice to the
     Corporation at the election by the holders


                                       87

   88



     of seventy-five percent (75%) of the outstanding Class G Preferred, voting
     on an As Converted Basis.

          (b) Conversion Price. Each Class G Preferred shall be convertible at
     an office or agency referred to below into a number of fully paid and
     nonassessable shares of Common Stock (calculated as to each conversion to
     the nearest one-hundredth (1/100th) of a share) as is determined by
     dividing One and 85/100 Dollars ($1.85) by the Conversion Price in effect
     on the Conversion Date. As of the date this Amended and Restated
     Certificate of Incorporation was filed with the Secretary of State of
     Delaware, the price at which Common Stock shall initially be issuable upon
     conversion shall be One and 85/100 Dollars ($1.85) per share, which price
     may be adjusted from time to time as provided in Section 4(f) (the
     "Conversion Price").

          (c) Method of Conversion. In order to exercise such conversion
     privilege, the holder of any Class G Preferred to be converted shall
     present and surrender the certificate(s) representing such Class G
     Preferred during usual business hours at any office or agency of the
     Corporation maintained for the transfer of Class G Preferred and shall
     deliver a written notice of its election to convert the Class G Preferred
     represented by such certificate(s), or any portion thereof, specified in
     such notice. Such notice shall also state the name or names (with address)
     in which the certificate or certificates for Common Stock issuable on such
     conversion shall be issued. If so required by the Corporation, any
     certificate for Class G Preferred surrendered for conversion shall be
     accompanied by instruments of transfer, in form satisfactory to the
     Corporation, duly executed by the holder of such Class G Preferred or such
     holder's duly authorized representative. Each conversion of Class G
     Preferred shall be deemed to have been effected on the date (the
     "Conversion Date") on which the certificate or certificates representing
     such Class G Preferred shall have been surrendered and any required notice
     and instruments of transfer received as aforesaid. Subject to the
     provisions of Section 4(f)(viii), the person or persons in whose name or
     names any certificate or certificates for Common Stock shall be issuable
     upon such conversion shall be deemed to have become the holder or holders
     of record of such Common Stock immediately prior to the close of business
     on the Conversion Date. Subject to the provisions of Section (f)(viii), as
     promptly as practicable (and in any event within two (2) business days)
     after the presentation and surrender for conversion, as herein provided, of
     any certificate or certificates for Class G Preferred, the Corporation
     shall issue and deliver at such office or agency, to or upon the written
     order of the holder thereof, a certificate or certificates for the number
     of shares of Common Stock issuable upon such conversion. In case any
     certificate or certificates for Class G Preferred shall be surrendered for
     conversion of less than all of the Class G Preferred represented thereby,
     the Corporation shall deliver at such office or agency, to or upon the
     written order of the holder thereof, a certificate or certificates for the
     number of Class G Preferred represented by such surrendered certificate or
     certificates which are not converted. The issuance of certificates for
     Common Stock issuable upon the conversion of Class G Preferred, and the
     issuance of certificates representing Class G Preferred which are not
     converted as described above, shall be at the Corporation's expense and
     without charge to the converting holder for any tax imposed on the
     Corporation in respect of the issue thereof. The Corporation shall not,
     however, be required to pay any tax which may be payable with respect to
     any transfer involved in the issue and delivery of any certificate in a
     name other than that of the holder


                                       88

   89



     of the Class G Preferred and the Corporation shall not be required to issue
     or deliver any such certificate unless and until the person requesting the
     issue thereof shall have paid to the Corporation the amount of such tax or
     has established to the satisfaction of the Corporation that such tax has
     been paid.

          (d) No Adjustment for Dividends. With respect to any conversion of
     Class G Preferred into Common Stock pursuant to this Section 4, no
     adjustment shall be made for dividends declared but as yet unpaid on the
     Class G Preferred as of any record date prior to the Conversion Date;
     provided, however, that upon the conversion of such Class G Preferred, the
     dividend declared but as yet unpaid on the Class G Preferred shall be
     payable on the Common Stock issued upon such conversion as if such Common
     Stock were outstanding as of the record date for the determination of
     holders entitled to receive said dividend.

          (e) Fractional Shares. If more than one Class G Preferred share shall
     be surrendered for conversion at one time by the same holder, the number of
     full Common Stock issuable upon conversion thereof shall be computed on the
     basis of the aggregate number of Class G Preferred shares so surrendered.
     If any fractional interest in a Share of Common Stock would be deliverable
     upon the conversion of any Class G Preferred, the Corporation shall issue a
     certificate which shall evidence and include such fractional interest in
     the Common Stock.

          (f) Conversion Price Adjustments. The Conversion Price for the Class G
     Preferred shall be subject to adjustment from time to time as follows:

               (i) Common Stock Issued at Less Than the Conversion Price. In the
          event that the Corporation shall issue Additional Common Shares (as
          defined in Article 4, Section C. 4(f)(i) of this Amended and Restated
          Certificate of Incorporation), the Conversion Price in effect
          immediately prior to each such issuance shall be reduced to a price
          determined by multiplying the then current Conversion Price by a
          fraction (A) the numerator of which shall be the sum of (1) the number
          of shares of Common Stock outstanding immediately prior to such
          issuance, plus (2) the number of shares of Common Stock that the
          aggregate consideration received by the Company for the total number
          of Additional Common Shares so issued would purchase at such
          Conversion Price, and (B) the denominator of which shall be the number
          of shares of Common Stock outstanding immediately prior to such
          issuance plus the number of Additional Common Stock so issued.

          For the purposes of any adjustment of the Conversion Price pursuant to
     this Section 4(f)(i), the following provisions shall be applicable:

                    (A) Cash. In the case of the issuance of Common Stock for
               cash, the amount of the consideration received by the Corporation
               shall be deemed to be the amount of the cash proceeds received by
               the Corporation for such Common Stock before deducting therefrom
               any reasonable discounts, commissions, taxes or other expenses
               allowed, paid or incurred


                                       89

   90



               by the Corporation for any underwriting or otherwise in
               connection with the issuance and sale thereof.

                    (B) Consideration Other Than Cash. In the case of the
               issuance of Common Stock (other than upon the conversion of
               shares of capital stock or other securities of the Corporation)
               for a consideration in whole or in part other than cash,
               including securities acquired in exchange therefor (other than
               securities by their terms so exchangeable), the consideration
               other than cash shall be deemed to be the fair value thereof (as
               determined in good faith by the Board of Directors of the
               Corporation, whose determination shall be conclusive to the
               extent reasonable), irrespective of any accounting treatment;
               provided, that such fair value as determined by the Board of
               Directors shall not exceed the aggregate Current Market Price (as
               defined in Section 4(g)) of the Common Stock being issued as of
               the date the Board of Directors authorizes the issuance of such
               Common Stock.

                    (C) Options and Convertible Securities. In the case of the
               issuance of (i) options, warrants or other rights to purchase or
               acquire Common Stock (whether or not at the time exercisable)
               other than Excluded Shares, (ii) securities by their terms
               convertible into or exchangeable for Common Stock (whether or not
               at the time so convertible or exchangeable), or (iii) options,
               warrants or rights to purchase such convertible or exchangeable
               securities (whether or not at the time exercisable):

                         (1) the aggregate maximum number of shares of Common
                    Stock deliverable upon exercise of such options, warrants or
                    other rights to purchase or acquire Common Stock shall be
                    deemed to have been issued at the time such options,
                    warrants or other rights become exercisable and for a
                    consideration equal to the consideration (determined in the
                    manner provided in Sections 4(f)(i)(A) and (B)), if any,
                    received by the Corporation upon the issuance of such
                    options, warrants or other rights plus the minimum purchase
                    price provided in such options, warrants or other rights for
                    the Common Stock covered thereby;

                         (2) the aggregate maximum number of shares of Common
                    Stock deliverable upon conversion of or in exchange for any
                    such convertible or exchangeable securities, or upon the
                    exercise of options, warrants or other rights to purchase or
                    acquire such convertible or exchangeable securities and the
                    subsequent conversion or exchange thereof, shall be deemed
                    to have been issued at the time such securities become
                    convertible or exchangeable or such options, warrants or
                    other rights become exercisable and for a consideration
                    equal to the consideration, if any, received by the
                    Corporation for any such securities and related options,
                    warrants or other rights (excluding any cash received on


                                       90

   91



                    account of accrued interest or accrued dividends), plus the
                    additional consideration, if any, to be received by the
                    Corporation upon the conversion or exchange of such
                    securities and the exercise of any related options, warrants
                    or other rights (the consideration in each case to be
                    determined in the manner provided in Sections 4(f)(i)(A) and
                    (B));

                         (3) on any change in the number of shares of Common
                    Stock deliverable upon exercise of any such options,
                    warrants or other rights which have become exercisable or
                    conversion of or exchange of such convertible or
                    exchangeable securities which have become convertible or
                    exchangeable, or any change in the consideration to be
                    received by the Corporation upon such exercise, conversion
                    or exchange, including, but not limited to, a change
                    resulting from any subdivision, split-up, combination or
                    reclassification thereof, the Conversion Price as then in
                    effect shall forthwith be readjusted to such Conversion
                    Price as would have been obtained had an adjustment been
                    made upon such options, warrants or other rights not
                    exercised becoming exercisable prior to such change, or
                    securities not converted or exchanged becoming convertible
                    or exchangeable prior to such change, upon the basis of such
                    change but only if as a result of such adjustment the
                    Conversion Price then in effect is thereby reduced;

                         (4) on the expiration or cancellation of any such
                    options, warrants or other rights, or the termination of the
                    right to convert or exchange such convertible or
                    exchangeable securities, if the Conversion Price shall have
                    been adjusted upon such becoming exercisable, convertible or
                    exchangeable, such Conversion Price shall forthwith be
                    readjusted to such Conversion Price as would have been
                    obtained had an adjustment been made upon such options,
                    warrants or other rights becoming exercisable or securities
                    becoming convertible or exchangeable on the basis of the
                    issuance of only the number of shares of Common Stock
                    actually issued upon the exercise of such options, warrants
                    or other rights, or upon the conversion or exchange of such
                    securities; and

                         (5) if the Conversion Price shall have been adjusted
                    upon such options, warrants or other rights becoming
                    exercisable or such convertible or exchangeable securities
                    becoming convertible or exchangeable, no further adjustment
                    of the Conversion Price shall be made for the actual
                    issuance of Common Stock upon the exercise, conversion or
                    exchange thereof.

               (ii) Excluded Shares. "Excluded Shares" has the meaning given to
          it in Article 4, Section C. 4(f)(ii) of this Amended and Restated
          Certificate of Incorporation.



                                       91

   92



               (iii) Stock Dividends; Stock Splits, Etc. If the number of shares
          of Common Stock outstanding at any time after the date of issuance of
          the Class G Preferred is increased by a stock dividend payable in
          Common Stock or by a subdivision or split-up of Common Stock, then
          immediately after the record date fixed for the determination of
          holders of Common Stock entitled to receive such stock dividend or the
          effective date of such subdivision or split-up, as the case may be,
          the Conversion Price shall be appropriately adjusted so that the
          holder of any Class G Preferred thereafter converted shall be entitled
          to receive the number of shares of Common Stock of the Corporation
          which such holder would have owned immediately following such action
          had such Class G Preferred been converted immediately prior thereto.

               (iv) Combination of Shares. If the number of shares of Common
          Stock outstanding at any time after the date of issuance of the Class
          F Preferred is decreased by a combination of the outstanding Common
          Stock, then immediately after the effective date of such combination,
          the Conversion Price shall be appropriately increased so that the
          holder of any Class G Preferred thereafter converted shall be entitled
          to receive the number of shares of Common Stock of the Corporation
          which such holder would have owned immediately following such action
          had such Class G Preferred been converted immediately prior thereto.

               (v) Reorganizations, Etc. In the case of any capital
          reorganization of the Corporation, any reclassification of Common
          Stock, the consolidation of the Corporation with or the merger of the
          Corporation with or into any other entity (other than a reorganization
          or merger solely for the purpose of the change in the state of
          incorporation of the Corporation) or the sale, lease or other transfer
          of all or substantially all of the assets of the Corporation to any
          other person or entity, each Class G Preferred shall after such
          capital reorganization, reclassification, consolidation, merger, sale,
          lease or other transfer be convertible into the number of shares of
          capital stock or other securities or property to which the Common
          Stock issuable (at the time of such capital reorganization,
          reclassification, consolidation, merger, sale, lease or other
          transfer) upon conversion of such Class G Preferred would have been
          entitled upon such capital reorganization, reclassification,
          consolidation, merger, sale, lease or other transfer; and in any such
          case, if necessary, the provisions set forth herein with respect to
          the rights and interests thereafter of the holders of the Class G
          Preferred shall be appropriately adjusted so as to be applicable, as
          nearly as may reasonably be possible, to any shares of capital stock
          or other securities or property thereafter deliverable on the
          conversion of the Class G Preferred. The subdivision or combination of
          Common Stock issuable upon conversion of Class G Preferred at any time
          outstanding into a greater or lesser number of shares of Common Stock
          (whether with or without par value) shall not be deemed to be a
          reclassification of the Common Stock of the Corporation for the
          purposes of this Section 4(f)(v).

               (vi) Evidences of Indebtedness or Assets. In case the Corporation
          shall declare a distribution payable in securities of other Persons,
          evidences of indebtedness issued by the Corporation or other Persons
          or assets (excluding cash dividends or dividends payable solely in
          Common Stock) then, in each such case,


                                       92

   93



          each holder of Class G Preferred shall be entitled to receive a
          proportionate share of any such distribution as if it had converted
          into the number of shares of Common Stock of the Corporation into
          which its Class G Preferred would have been convertible as of the
          record date fixed for the determination of the holders of outstanding
          shares of Common Stock of the Corporation entitled to receive such
          distribution.

               (vii) Rounding of Calculations; Minimum Adjustment. All
          calculations under this Section 4(f) shall be made to the nearest cent
          or to the nearest one-hundredth (1/100th) of a share, as the case may
          be. Any provision of this Section 4 to the contrary notwithstanding,
          no adjustment in the Conversion Price shall be made if the amount of
          such adjustment would be less than one cent ($0.01), but any such
          amount shall be carried forward and an adjustment with respect thereto
          shall be made at the time of, and together with, any subsequent
          adjustment which, together with such amount and any other amount or
          amounts so carried forward, shall aggregate one cent ($0.01) or more.

               (viii) Timing of Issuance of Additional Common Stock Upon Certain
          Adjustments. In any case in which the provisions of this Section 4(f)
          shall require that an adjustment shall become effective immediately
          after the record date for an event, the Corporation may defer until
          the occurrence of such event the issuing to the holder of any Class G
          Preferred converted after such record date and before the occurrence
          of such event the additional Common Stock issuable upon such
          conversion by reason of the adjustment required by such event over and
          above the Common Stock issuable upon such conversion before giving
          effect to such adjustment; provided, that the Corporation upon request
          shall deliver to such holder a due bill or other appropriate
          instrument evidencing such holder's right to receive such additional
          shares upon the occurrence of the event requiring such adjustment.

               (ix) Applicable Adjustment. In any case in which the provisions
          of this Section 4(f) shall require an adjustment to the Conversion
          Price for the Class G Preferred, the applicable adjustment shall be
          the largest adjustment lowering the Conversion Price resulting from
          the application of any appropriate provision of this Section 4(f) to
          such event.

          (g) Current Market Price. "Current Market Price" shall have the
     meaning given in Article 4, Section C. 4.(g) of this Amended and Restated
     Certificate of Incorporation; provided, that, if within fifteen (15) days
     of receiving notice of an event under Section 4(f) requiring the
     calculation of the Current Market Price a holder of at least ten percent
     (10%) of the currently outstanding Class G Preferred requests the
     appointment of an independent appraiser, the Board of Directors shall,
     within ten (10) days of such request, appoint as an independent appraiser a
     nationally-known independent public accounting firm or investment bank and
     the Board of Directors shall direct such independent appraiser to conduct
     an appraisal and make a report on the Current Market Price of a Share of
     Common Stock within thirty (30) days of its appointment. The determination
     of the Current Market Price by such independent appraiser shall be final
     and binding upon the Corporation and the holders of Class G


                                       93

   94



     Preferred. The costs of such independent appraiser shall be paid by the
     Corporation. Any independent appraiser so utilized shall agree to treat all
     information supplied by the Corporation in a confidential manner.

          (h) Statement Regarding Adjustments. Whenever the Conversion Price is
     adjusted as herein provided:

               (i) the Corporation shall compute the adjusted Conversion Price
          in accordance with this Section 4 and shall prepare a certificate
          signed by the Treasurer of the Corporation setting forth the adjusted
          Conversion Price and the facts requiring such adjustment, and such
          certificate shall forthwith be filed at the office of the transfer
          agent or agents, if any, for the Class G Preferred and at the
          principal office of the Corporation; and

               (ii) a notice stating that the Conversion Price has been adjusted
          and setting forth the adjusted Conversion Price and the facts
          requiring such adjustment shall, as soon as practicable, be mailed to
          the holders of record of the outstanding Class G Preferred. Where
          appropriate, such notice may be given in advance and may be included
          as part of a notice required to be mailed under the provisions of
          Section 4(j).

          (i) Cancellation. All Class G Preferred which shall have been
     surrendered for conversion as herein provided in this Section 4 shall no
     longer be deemed to be outstanding and all rights with respect to such
     Class G Preferred, including the rights, if any, to receive notices and to
     vote, shall forthwith cease and terminate, except only the right of the
     holders thereof to receive Common Stock or other assets or property in
     exchange therefor.

          (j) Notice to Holders. In the event that:

               (i) the Corporation shall take action to make any distribution or
          dividend to the holders of any class of its capital stock;

               (ii) the Corporation shall take action to offer for subscription
          pro rata to the holders of any class of its capital stock securities
          of any kind;

               (iii) the Corporation shall take action to accomplish any capital
          reorganization, or reclassification of the capital stock of the
          Corporation (other than a subdivision, split-up or combination of its
          Common Stock), or consolidation or merger to which the Corporation is
          a party and for which approval of any stockholders of the Corporation
          is required, or the sale or transfer of all or substantially all of
          the assets of the Corporation; or

               (iv) the Corporation shall take action looking to a voluntary or
          involuntary dissolution, liquidation or winding up of the affairs of
          the Corporation;



                                       94

   95



          then the Corporation shall (x) in case of any such distribution,
          dividend or offering of subscription rights, at least ten (10) days
          prior to the date or expected date on which the books of the
          Corporation shall close or a record shall be taken for the
          determination of holders entitled to such distribution or subscription
          rights, and (y) in the case of any such reorganization,
          reclassification, consolidation, merger, sale, transfer, dissolution,
          liquidation or winding up, at least ten (10) days prior to the date or
          expected date when the same shall take place, cause written notice
          thereof to be mailed to each holder of Class G Preferred at such
          holder's address as shown on the books of the Corporation. The notice
          to be given in accordance with this Section 4 (j) shall also specify
          (x) the date or expected date on which the holders of any class of the
          Corporation's capital stock shall be entitled thereto, and (y) the
          date or expected date on which the holders of any class of the
          Corporation's capital stock shall be entitled to exchange their shares
          for securities or other property deliverable upon such reorganization,
          reclassification, consolidation, merger, sale, transfer, dissolution,
          liquidation or winding up, as the case may be.

               (k) Reservation of Shares. The Corporation shall at all times
          reserve and keep available, free from preemptive rights, out of its
          treasury shares or its authorized but unissued Common Stock, for the
          purpose of effecting the conversion of the Class F Preferred, the full
          number of shares of Common Stock then deliverable upon the conversion
          of all Class G Preferred then outstanding.

               (l) Reclassification of Common Stock. For the purposes of this
          Section 4, the term "Common Stock" shall mean (a) the class of stock
          designated as the Common Stock of the Corporation on the date this
          Amended and Restated Certificate of Incorporation is filed with the
          Secretary of State of Delaware, or (b) any other class of stock
          resulting from successive changes or reclassifications of such Common
          Stock consisting solely of changes in par value or from no par value
          to par value, or from par value to no par value. If at any time as a
          result of an adjustment made pursuant to the provisions of Section
          4)(f)(v), the holder of any Class G Preferred thereafter surrendered
          for conversion shall become entitled to receive any shares of the
          Corporation other than Common Stock, and the number of such other
          shares so receivable upon conversion of any Class G Preferred shall be
          subject to adjustment from time to time in a manner and on terms as
          nearly equivalent as practicable to the provisions with respect to the
          Common Stock contained in Section 4(f)(v), and the other provisions of
          this Section 4 with respect to the Common Stock shall apply on like
          terms to any such other shares.

               (m) Treasury Shares. For the purpose of this Section 4, the sale
          or other disposition of any Common Stock of the Corporation
          theretofore held in its treasury shall be deemed to be an issuance
          thereof.

               (n) Approvals. If any Common Stock to be reserved for the purpose
          of conversion of Class G Preferred requires registration with or
          approval of any governmental authority under any Federal or state law
          or of the NASDAQ System before such shares may be validly issued or
          delivered upon conversion, the Corporation will in good faith and as
          expeditiously as possible secure such registration or approval, as the
          case may be. If, and so long as, any Common Stock into which the Class
          G Preferred are then convertible are listed on any national securities
          exchange, the Corporation will, if


                                       95

   96



          permitted by the rules of such exchange, list and keep listed on such
          exchange, upon official notice of issuance, all of such Common Stock
          issuable upon conversion.

               (o) Valid Issuance. All Common Stock that may be issued upon
          conversion of the Class G Preferred will upon issuance by the
          Corporation be duly and validly issued, fully paid and nonassessable
          and free from all taxes, liens and charges with respect to the
          issuance thereof, and the Corporation shall take no action which will
          cause a contrary result (including, without limitation, any action
          which would cause the Conversion Price to be less than the par value,
          if any, of the Common Stock).

     The following is a statement of the express terms, powers, preferences,

BLANK CHECK PREFERRED STOCK

          Subject to the provisions of this Article Fourth and the express
     provisions of each series of Blank Check Preferred and the outstanding
     Preferred Stock, the Board of Directors is hereby empowered to cause the
     Blank Check Preferred to be issued from time to time for such consideration
     as it may from time to time fix, and to cause such Blank Check Preferred to
     be issued in one or more series, with such voting powers, full or limited,
     or no voting powers, and such designations, preferences and relative,
     participating, optional and other special rights, and qualifications,
     limitations or restrictions thereof, as shall be stated and expressed in
     the resolution or resolutions providing for the issues of such stock
     adopted by the Board of Directors. Each series of Blank Check Preferred
     shall be distinctly designated. Except in respect of the particulars fixed
     by the Board of Directors for each series as permitted hereby, all shares
     of Blank Check Preferred shall be of equal rank and shall be identical. All
     shares of any one series of Blank Check Preferred so designated by the
     Board of Directors shall be alike in every particular, except that shares
     of any one series issued at different times may differ as to the dates from
     which dividends thereon shall be cumulative. The voting rights, if any, of
     each such series and the preferences and relative, participating, optional
     and other special rights of each such series and the qualifications,
     limitations and restrictions thereof, if any, may differ from those of any
     and all other series at any time outstanding; and the Board of Directors is
     hereby expressly granted authority to fix, by resolutions duly adopted
     prior to the issuance of any shares of a particular series of Blank Check
     Preferred so designated by the Board of Directors, the voting powers of
     stock of such series, if any, and the designations, preferences and
     relative, participating, optional and other special rights and the
     qualifications, limitations and restrictions thereof, if any, for such
     series, including, without limitation, the following:

               (a) The distinctive designation of and the number of shares of
          Blank Check Preferred which shall constitute such series; provided,
          that such number may be increased (but not above the total number of
          authorized shares of Blank Check Preferred) or decreased (but not
          below the number of shares thereof then outstanding) from time to time
          by like action of the Board of Directors;

               (b) The rate and time at which, and the terms and conditions upon
          which, dividends, if any, on Blank Check Preferred of such series
          shall be paid, the extent of the preference or relation, if any, of
          such dividends to the dividends payable on any other series of Blank
          Check Preferred or any other class of stock of the Corporation and
          whether such dividends shall be cumulative or non-cumulative;

               (c) The right, if any, of the holders of Blank Check Preferred of
          such series to convert the same into, or exchange the same for, shares
          of any other class


                                       97

   98



          of stock or any series of any class of stock of the Corporation and
          the terms and conditions of such conversion or exchange;

               (d) Whether or not Blank Check Preferred of such series shall be
          subject to redemption, and the redemption price or prices and the time
          or times at which, and the terms and conditions upon which, Blank
          Check Preferred of such series may be redeemed;

               (e) The rights, if any, of the holders of Blank Check Preferred
          of such series upon the dissolution, liquidation or winding-up of the
          Corporation, whether voluntary or involuntary;

               (f) The terms of the sinking fund or redemption or purchase
          account, if any, to be provided for the Blank Check Preferred of such
          series; and

               (g) The voting powers, if any, of the holders of such series of
          Blank Check Preferred which may, without limiting the generality of
          the foregoing, include the right, voting as a series by itself or
          together with any other series of the Blank Check Preferred as a
          class, (i) to vote more or less than one vote per share on any or all
          matters voted by the stockholders, and (ii) to elect one or more
          directors of the Corporation if there has been a default in the
          payment of dividends on any one or more series of the Blank Check
          Preferred or under such other circumstances and upon such other
          condition as the Board of Directors may fix.

     SIXTH: The Corporation is to have perpetual existence.

     SEVENTH: In furtherance and not in limitation of the powers conferred by
statute, the board of directors is expressly authorized:

          To make, alter or repeal the bylaws of the Corporation.

          To authorize and cause to be executed mortgages and liens upon the
     real property of the Corporation.

          To set apart out of any of the funds of the Corporation available for
     dividends a reserve or reserves for any proper purpose and to abolish any

                                       98

   99



          By a majority of the whole board, to designate one or more committees,
     each committee to consist of one or more of the directors of the
     Corporation.

          When and as authorized by the stockholders in accordance with this
     Amended and Restated Certificate of Incorporation and applicable statutes,
     to sell, lease or exchange all or substantially all of the property and
     assets of the Corporation, including its goodwill and its corporate
     franchises, upon such terms and conditions and for such consideration
     (which may consist, in whole or in part, of money or property, including
     shares of stock in, and/or other securities of, any other corporation or
     corporations) as the Corporation's Board of Directors shall deem
     appropriate and in the best interests of the Corporation.

     EIGHTH: Meetings of stockholders may be held within or without the State of
Delaware, as the bylaws may provide. The books of the Corporation may be kept
(subject to any provision contained in the statutes) outside the State of
Delaware at such place or places as may be designated from time to time by the
board of directors or in the bylaws of the Corporation. Elections of directors
need not be by written ballot unless the bylaws of the Corporation shall so
provide.

     NINTH: The Corporation reserves the right to amend, alter, change or repeal
any provision contained in this Amended and Restated Certificate of
Incorporation, in the manner now or hereafter prescribed by statute, and all
rights conferred upon stockholders herein are granted subject to this
reservation.

     TENTH: No director shall be personally liable to the Corporation or any of
its stockholders for monetary damages for breach of fiduciary duty as a
director, except for liability (1) for any breach of the director's duty of
loyalty to the Corporation or its stockholders, (2) for acts or omissions not in
good faith or which involve intentional misconduct or a knowing violation of
law, (3) under Section 174 of the Delaware General Corporation Law, or (4) for
any transaction from which the director derived an improper personal benefit. If
the Delaware General Corporation Law hereafter is amended to authorize the
further elimination or limitation of the liability of directors, then the
liability of a director of the Corporation, in addition to the limitations on
personal liability provided herein, shall be limited to the fullest extent
permitted by the amended Delaware General Corporation Law. Any repeal or
modification of this Article Tenth shall be prospective only, and shall not
adversely affect any limitation on the personal liability of a director of the
Corporation existing at the time of such repeal or modification.

     ELEVENTH: A. Each person who was or is made a party to or is threatened to
be made a party to or is involved in any action, suit or proceeding, whether
civil, criminal, administrative or investigative (hereinafter a "proceeding"),
by reason of the fact that he or she, or a person of whom he or she is the legal
representative, is or was a director or officer of the Corporation or is or was
serving at the request of the Corporation as a director, officer, employee or
agent of another corporation or of a partnership, joint venture, trust or other
enterprise, including service with respect to employee benefit plans, whether
the basis of such proceeding is alleged action in an official capacity as a
director, officer, employee or agent or in any other capacity while serving as a
director, officer, employee or agent, shall be indemnified and held harmless by
the Corporation to the fullest extent, authorized by the Delaware General
Corporation Law, as the same exists or may hereafter be amended (but, in the
case of any such amendment, only to the extent that such amendment permits the
Corporation to provide broader indemnification rights


                                       99

   100



than said law permitted the Corporation to provide prior to such amendment),
against all expense, liability and loss (including attorneys' fees, judgments,
fines, ERISA, excise taxes or penalties and amounts paid or to be paid in
settlement) reasonably incurred or suffered by such person in connection
therewith and such indemnification shall continue as to a person who has ceased
to be a director, officer, employee or agent and shall inure to the benefit of
his or her heirs, executors and administrators; provided, however, that, except
as provided in subsection B of this Article Eleventh, the Corporation shall
indemnify any such person seeking indemnification in connection with a
proceeding (or part thereof) initiated by such person only if such proceeding
(or part thereof) was authorized by the Board of Directors of the Corporation.
The right to indemnification conferred in this Article Eleventh shall be a
contract right and shall include the right to be paid by the Corporation the
expenses incurred in defending any such proceeding in advance of its final
disposition; provided, however, that if the Delaware General Corporation Law
requires, the payment of such expenses incurred by a director or officer in his
or her capacity as a director or officer (and not in any other capacity in which
service was or is rendered by such person while a director or officer,
including, without limitation, service to an employee benefit plan) in advance
of the final disposition of a proceeding shall be made only upon delivery to the
Corporation of an undertaking, by or on behalf of such director or officer, to
repay all amounts so advanced if it shall ultimately be determined that such
director or officer is not entitled to be indemnified under this Article
Eleventh or otherwise. The Corporation may, by action of its Board of Directors,
provide indemnification to employees and agents of the Corporation with the same
scope and effect as the foregoing indemnification of directors and officers.

     B. If a claim under subsection A of this Article Eleventh is not paid in
full by the Corporation within thirty (30) days after a written claim has been
received by the Corporation, the claimant may at any time thereafter bring suit
against the Corporation to recover the unpaid amount of the claim and, if
successful in whole or in part, the claimant shall be entitled to be paid also
the expense of prosecuting such claim. It shall be a defense to any such action
(other than an action brought to enforce a claim for expenses incurred in
defending any proceeding in advance of its final disposition where the required
undertaking, if any is required, has been tendered to the Corporation) that the
claimant has not met the standards of conduct which make it permissible under
the Delaware General Corporation Law for the Corporation to indemnify the
claimant for the amount claimed, but the burden of proving such defense shall be
on the Corporation. Neither the failure of the Corporation (including its Board
of Directors, independent legal counsel, or its stockholders) to have made a
determination prior to the commencement of such action that indemnification of
the claimant is proper in the circumstances because he or she has met the
applicable standard of conduct set forth in the Delaware General Corporation
Law, nor an actual determination by the Corporation (including its Board of
Directors, independent legal counsel, or its stockholders) that the claimant has
not met such applicable standard of conduct, shall be a defense to the action or
create a presumption that the claimant has not met the applicable standard of
conduct.

     C. The right to indemnification and the payment of expenses incurred in
defending a proceeding in advance of its final disposition conferred in this
Article Eleventh shall not be exclusive of any other right which any person may
have or hereafter acquire under any statute, provision of this Certificate of
Incorporation, bylaw, agreement, vote of stockholders or disinterested directors
or otherwise.



                                       100

   101



     D. The Corporation may maintain insurance, at its expense, to protect
itself and any director, officer, employee or agent of the Corporation or
another corporation, partnership, joint venture, trust or other enterprise
against any such expense, liability or loss, whether or not the Corporation
would have the power to indemnify such person against such expense, liability or
loss under the Delaware General Corporation Law.

     E. As used in this Article Eleventh, references to "the Corporation" shall
include, in addition to the resulting or surviving corporation, any constituent
corporation absorbed in a consolidation or merger which, if its separate
existence had continued, would have had power and authority to indemnify its
directors, officers, employees and agents, so that any person who is or was a
director, officer, employee or agent of such constituent corporation, or is or
was serving at the request of such constituent corporation as a director,
officer, employee or agent of another corporation, partnership, joint venture,
trust, or other enterprise, shall stand in the same position under the
provisions of this Article Eleventh with respect to the resulting or surviving
corporation as he would have with respect to such constituent corporation if its
separate existence had continued.

     F. If this Article Eleventh or any portion hereof shall be invalidated on
any ground by any court of competent jurisdiction, then the Corporation shall
nevertheless indemnify each director, officer, employee and agent of the
Corporation as to expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement with respect to any action, suit or proceeding,
whether civil, criminal, administrative or investigative, including a grand jury
proceeding and an action by the Corporation, to the fullest extent permitted by
any applicable portion of this Article Eleventh that shall not have been
invalidated or by any other applicable law.
