        dividends, and shall be cumulative so that if such dividends on the
        Class A1 Preferred Stock shall not have been paid, or declared and set

               (a)    In the event of any Liquidation of the Company, the
        Preferred A1 Holders shall be entitled to be paid out of the assets of
        the Company legally available for distribution to its stockholders,
        after and subject to the payment in full of all amounts required to be
        distributed to the holders of Voting Preferred Stock and any other class
        or series of stock of the Company ranking on liquidation prior and in
        preference to the Class A1 Preferred Stock (collectively referred to as
        "Senior Preferred Stock"), but before any payment shall be made to the
        holders of Junior Stock by reason of their ownership thereof, an amount
        equal to the Liquidation Value per share of Class A1 Preferred Stock. If
        upon any such Liquidation of the Company the remaining assets of the
        Company available for distribution to its stockholders shall be

        the full amount to which they shall be entitled, the holders of shares
        of Class A1 Preferred Stock and the holders of shares of Class A2
        Preferred Stock, Class B1 Preferred Stock, Class C1 Preferred Stock,
        Class D Preferred Stock, Class E Preferred Stock and any other class or
        series of stock ranking on liquidation on a parity with the Class A1
        Preferred Stock shall share ratably in any distribution of the remaining
        assets and funds of the Company in proportion to the respective amounts
        which would otherwise be payable in respect of the shares held by them
        upon such distribution if all amounts payable on or with respect to such
        shares were paid in full.

               (b)    The merger or consolidation of the Company into or with
        another corporation which results in the exchange of outstanding shares
        of the Company for securities or other consideration issued or paid or
        caused to be issued or paid by such other corporation or an affiliate
        thereof (except if such merger or consolidation does not result in the
        transfer of more than 50 percent of the voting securities of the
        Company), or the sale of all or substantially all the assets of the
        Company, shall be deemed to be a Liquidation of the Company for purposes
        of this Section 3 of this subsection A1, unless the Requisite Preferred
        A1 Holders vote otherwise. The amount deemed distributed to the holders
        of Class A1 Preferred Stock upon any such merger or consolidation shall
        be the cash or the value of the property, rights and/or securities
        distributed to such holders by the acquiring person, firm or other
        entity. The value of such property, rights or other securities shall be
        determined in good faith by the Board.

        4.      Voting Rights.

               (a)    Except as required by law and pursuant to paragraphs (b),
        (c) and (d) below, the Preferred A1 Holders shall not be entitled to

               of Class A1 Preferred Stock other than as contemplated by the

               Designations of Preferred Stock;

                      (ii)   reclassify, cancel or in any manner alter or change
               the designations, preferences, privileges or relative, optional
               or other special rights, or the qualifications, limitations or
               restrictions thereof, of the Class A1 Preferred Stock;

                      (iii)  amend, repeal or modify any provision of this
               subsection A1 of this Designations of Preferred Stock; or

                      (iv)   amend, repeal or modify any provision of the
               Certificate of Incorporation or By-laws in a manner that would
               adversely affect the preferences, privileges or rights of the
               Preferred A1 Holders.

               (c)

               Preferred A1/A2 Holders shall have the right to have that number

               shall at all times and from time to time be equal to that number
               of nominees to the Board that the Preferred A1/A2 Holders are
               then entitled to designate less the number of such nominees as

                      (ii)   The Company will give each Observer reasonable
               prior notice (it being agreed that the same prior notice given to
               the Board shall be deemed reasonable prior notice) in any manner

               all papers which may be distributed from time to time to the
               directors of the Company at such time as such papers are so
               distributed to them, including copies of any written consent.

5.      Redemption.

        (a)    Subject to the Company having funds legally available for such
purpose, the Company shall redeem all of the shares of the Class A1 Preferred
Stock then outstanding, on the Maturity Date. The per share redemption price at
which shares of Class A1 Preferred Stock are to be redeemed pursuant to this
Section 5(a) of this subsection A1 shall be equal to the Liquidation Value (the
"Redemption Price").

        (b)    In the event the Company or any of its Subsidiaries consummates a
public or private offering for cash of capital stock or other equity interests,
the Company shall be required to apply 50% of the Net Proceeds of such offering
toward the redemption of shares of Preferred Stock (other than Voting Preferred
Stock), on a pro rata basis (determined on the basis of the number of shares of
Preferred Stock (other than Voting Preferred Stock), held by such holder over
the total number of shares of Preferred Stock (other than Voting Preferred
Stock) outstanding) from the Holders of Preferred Stock at the Redemption Price.

        (c)    In addition to the Company's mandatory redemption obligations as
set forth in Sections 5(a) and (b) of this subsection A1, the Company shall have
the option to redeem a minimum of $1 million of Original Cost of Class A1
Preferred Stock and integral multiples of $100,000 thereafter at the Liquidation
Value thereof. Any shares to be redeemed pursuant to this Section 5(c) of this
subsection A1 shall be selected for redemption at the discretion of, or in a
manner approved by, the Board. Notwithstanding any of the other provisions of
this Section 5 of this subsection A1, so long as any Preferred A1/A2 Holder
remains a Significant Holder, the Company shall not be permitted to redeem or
retire all outstanding shares of Class A1 Preferred Stock, but shall instead
allow such Significant Holder to remain the holder of one (1) share of Class A1
Preferred Stock.

        (d)    On and after any date set for redemption (the "Redemption Date")
pursuant to this Section 5 of this subsection A1 (unless default shall be made
by the Company in the payment of the Redemption Price, in which event such
rights shall be exercisable until such default is cured), all rights in respect
of the shares of the Class A1 Preferred Stock to be redeemed, except the right
to receive the Redemption Price, shall cease and terminate, and such shares
shall no longer be deemed to be outstanding, whether or not the certificates
representing such shares have been received by the Company.

        (e)    Any communication or notice relating to redemption given pursuant
to this Section 5 of this subsection A1 shall be sent by first-class certified
mail, return receipt requested, postage prepaid, to the Preferred A1 Holders at
their respective addresses as the same shall appear on the books of the Company,
or to the Company at the address of its principal, or registered office, as the
case may be.

        (f)    At any time on or after the Redemption Date, the Preferred A1
Holders shall be entitled to receive the Redemption Price upon actual delivery
to the Company or its agents of the certificates representing the shares of the
Class A1 Preferred Stock to be redeemed.

        (g)    Any redemption payments by the Company pursuant to this Section 5
of this subsection A1 shall be paid in cash.


                                      -7-
<PAGE>   8

        (h)    Any shares of Class A1 Preferred Stock which are redeemed or
otherwise acquired by the Company shall be canceled and shall not be reissued,
sold or transferred as Class A1 Preferred Stock and the Board shall reduce the
number of authorized shares of Class A1 Preferred Stock by the number of shares
so redeemed or otherwise acquired.

6.      Maturity Default.

        (a)    The occurrence of any of the following events of default shall,
at the option of the Requisite Preferred Holders, constitute a Maturity Default:

               (i)    the Company fails to comply in any material respect with
        any of its obligations under any of the Transaction Documents or the
        Fundamental Documents;

               (ii)   a material default occurs under any mortgage, indenture or
        other instrument under which there may be secured or evidenced any
        indebtedness for money borrowed by the Company if the principal amount
        of such indebtedness aggregates $1,000,000 or more; or

               (iii)  the Company fails to comply with the provisions of Section
        7.2(g)(iv) of the Purchase Agreement.

        (b)    A default under clauses (a)(i) or (a)(ii) is not a Maturity
Default until the Company does not cure the default within 30 days of the
Company having Knowledge of such default. When a default is cured, it ceases.

        (c)    The Requisite Preferred Holders by notice to the Company may
waive an existing default or Maturity Default and its consequences. When a
default or Maturity Default is waived, it ceases.

7.      Exchange.

        (a)    The Requisite Preferred A1 Holders and the Company may agree at
any time and from time to time following the Exchange Triggering Date to
exchange all or any portion of the shares of Class A1 Preferred Stock
outstanding into the Company's Subordinated Debentures (the "Notes") to be
issued substantially in the form attached as Exhibit D to the Purchase Agreement
in the amount of $1,000 principal amount of Notes for each $1,000 of Liquidation
Value of Class A1 Preferred Stock; provided, however, that no such exchange may
be consummated unless full cumulative dividends (including, without duplication,
full cumulative dividends pro rata for the elapsed portion of the current
dividend period) on the Class A1 Preferred Stock to the date of exchange shall
have been paid. Notes shall be issued only in integral multiples of $1,000 at
the time of exchange. If any additional amounts ("Fractional Principal Amounts")
would otherwise be issuable to any holders of Preferred Stock, then the Company
shall, in lieu of issuing a Fractional Principal Amount therefor, pay in full
payment of the Company's obligation with respect to such Fractional Principal
Amount, to each Preferred A1 Holder an amount in cash equal to such Fractional
Principal Amount. Any and all exchange rights set forth in this subsection A1
shall be deemed to be a right of redemption. In the event that the Company
exercises its option to exchange any portion of the outstanding shares of Class
A1 Preferred Stock into Notes pursuant to this Section 7 of this subsection A1,
such shares to be exchanged shall be selected for exchange at the discretion of,
or in a manner approved by, the Board. Notwithstanding any of the other
provisions of this Section 7 of this subsection A1, so long as any Preferred A1
Holder remains a Significant Holder, the Company shall not be permitted to
exchange all outstanding shares of Class A1 Preferred Stock, but shall instead
allow such Significant Holder to remain the holder of one (1) share of Class A1
Preferred Stock.

        (b)    Any exchange pursuant to this Section 7 of this Subsection A1
shall be made upon not less than 30 days' notice prior to the date fixed for
exchange (the "Exchange Date"). The notice given shall state that, upon
surrender of their certificate or certificates to the Company, the holders of
Class A1 Preferred Stock will receive Notes in the amount set forth in Section
7(a) of this subsection A1 above and that, at the close of business on the
Exchange Date, all rights of the holders with respect to such shares so


                                      -8-
<PAGE>   9

called for exchange shall cease, except the right to receive the Notes in the
amount set forth in Section 7(a) of this subsection A1. Except as may be
otherwise required by applicable law, the form of the Notes may only be amended
or supplemented before the first Exchange Date which occurs with the affirmative
vote or consent of the Requisite Preferred A1 Holders. On or after such first
Exchange Date, the Notes may only be amended or supplemented as provided in the
Notes. The Company will cause the Notes to be authenticated on the Exchange
Date, and the Company will pay interest on the Notes at the rate and on the
dates specified in the Notes from and after the relevant Exchange Date.

        (subject to appropriate adjustments in the event of any stock dividend,
        stock split, combination or other similar recapitalization affecting
        such shares) per share per annum, and no more, payable in preference and

        Preferred Stock, Class B1 Preferred Stock, Class C1 Preferred Stock,

        in respect of dividends (such Common Stock and other inferior stock
        being collectively referred to as "Junior Stock"), when and as declared
        by the Board.

               (b)    Such dividends shall accrue with respect to each share of
        Class A2 Preferred Stock from the date on which such share is issued and
        outstanding and thereafter shall be deemed to accrue from day to day
        whether or not earned or declared and whether or not there exists
        profits, surplus or other funds legally available for the payment of
        dividends, and shall be cumulative so that if such dividends on the
        Class A2 Preferred Stock shall not have been paid, or declared and set

        Liquidation Value of such share and will remain a part thereof until
        such dividends are paid in full in cash. Each dividend paid in cash
        shall be mailed to the holders of record of the Class A2 Preferred Stock
        as their names and addresses appear on the share register of the Company
        or at the office of the transfer agent on the corresponding dividend
        payment date.

        3.      Liquidation.

               (a)    In the event of any Liquidation of the Company, the
        Preferred A2 Holders shall be entitled to be paid out of the assets of
        the Company legally available for distribution to its stockholders,
        after and subject to the payment in full of all amounts required to be
        distributed to the holders of Voting Preferred Stock and any other class
        or series of stock of the Company ranking on liquidation prior and in
        preference to the Class A2 Preferred Stock (collectively referred to as
        "Senior Preferred Stock"), but before any payment shall be made to the
        holders of Junior Stock by reason of their ownership thereof, an amount
        equal to the Liquidation Value per share of Class A2 Preferred Stock. If
        upon any such Liquidation of the Company the remaining assets of the
        Company available for distribution to its stockholders shall be
        insufficient to pay the holders of shares of Class A2 Preferred Stock
        the full amount to which they shall be entitled, the holders of shares
        of Class A2 Preferred Stock and the holders of shares of Class A1
        Preferred Stock, Class B1 Preferred Stock, Class C1 Preferred Stock,
        Class D Preferred Stock, Class E Preferred Stock and any other class or
        series of stock ranking on liquidation on a parity with the Class A2
        Preferred Stock shall share ratably in any distribution of the remaining
        assets and funds of the Company in proportion to the respective amounts
        which would otherwise be payable in respect of the shares held by them
        upon such distribution if all amounts payable on or with respect to such
        shares were paid in full.

               (b)    The merger or consolidation of the Company into or with
        another corporation which results in the exchange of outstanding shares
        of the Company for securities or other consideration issued or paid or
        caused to be issued or paid by such other corporation or an affiliate
        thereof (except if such merger or consolidation does not result in the
        transfer of more than 50 percent of the voting securities of the
        Company), or the sale of all or substantially all the assets of the
        Company, shall be deemed to be a Liquidation of the Company for purposes
        of this Section 3 of this subsection A2, unless the Requisite Preferred
        A2 Holders vote otherwise. The amount deemed distributed to the holders
        of Class A2 Preferred Stock upon any such merger or consolidation shall
        be the cash or the value of the property, rights and/or securities
        distributed to such holders by the acquiring person, firm or other
        entity. The value of such property, rights or other securities shall be
        determined in good faith by the Board.

        approval of the Requisite Preferred A2 Holders:

                      (i)    in any manner authorize, issue or sell any shares
               of Class A2 Preferred Stock other than as contemplated by the
               Purchase Agreement, the Preferred Shareholder Agreement or this
               Designations of Preferred Stock;

                      (ii)   reclassify, cancel or in any manner alter or change
               the designations, preferences, privileges or relative, optional
               or other special rights, or the qualifications, limitations or
               restrictions thereof, of the Class A2 Preferred Stock;

                      (iii)  amend, repeal or modify any provision of this
               subsection A2 of this Designations of Preferred Stock; or

                      (iv)   amend, repeal or modify any provision of the
               Certificate of Incorporation or By-laws in a manner that would
               adversely affect the preferences, privileges or rights of the
               Preferred A2 Holders.

               (c)

                      (i)    The Company hereby covenants that the Requisite
               Preferred A1/A2 Holders shall have the right to have that number
               of representatives (each such representative, an "Observer")
               determined as hereinafter provided present at all meetings of the
               Board. Such right shall from time to time be exercisable by
               delivery to the Company of written notice from the Requisite
               Preferred A1/A2 Holders specifying the names of such Observers.
               The number of Observers shall at all times and from time to time
               be equal to that number of nominees to the Board that the
               Preferred A1/A2 Holders are then entitled to designate less the
               number of such nominees as are then members of the Board.

                      (ii)   The Company will give each Observer reasonable
               prior notice (it being agreed that the same prior notice given to
               the Board shall be deemed reasonable prior notice) in any manner
               permitted in the Company's By-laws for notices to directors of
               the time and place of any proposed meeting of the Board, such
               notice in all cases to include true and complete copies of all
               documents furnished to any director in connection with such
               meeting. Each such Observer will be entitled to be present in
               person as an observer at any such meeting or, if a meeting is

        5.     Redemption.

               (a)    Subject to the Company having funds legally available for
        such purpose, the Company, on the Maturity Date, shall have the option
        of redeeming all the shares of outstanding Class A2 Preferred Stock for
        cash as described in Sections 5(d) - (h) below. If the Company does not
        redeem such shares on the Maturity Date, the Company shall pay full
        cumulative dividends (including, without duplication, full cumulative
        dividends pro rata for the elapsed portion of the current dividend
        period) on the Class A2 Preferred Stock to the Maturity Date and,
        immediately thereafter, each share of Class A2 Preferred Stock shall
        automatically be converted into one share of Class D Preferred Stock.

        subsection A2 shall be equal to the Liquidation Value (the "Redemption
        Price").

        Preferred Stock (other than Voting

<PAGE>   14

        Preferred Stock), on a pro rata basis (determined on the basis of the
        number of shares of Preferred Stock (other than Voting Preferred Stock),
        held by such holder over the total number of shares of Preferred Stock
        (other than Voting Preferred Stock) outstanding) from the Holders of
        Preferred Stock at the Redemption Price.

               (c)    In addition to the Company's obligations as set forth in
        Sections 5(a) and (b) of this subsection A2, the Company shall have the
        option to redeem a minimum of $1 million of Original Cost of Class A2
        Preferred Stock and integral multiples of $100,000 thereafter at the

        Section 5(c) of this subsection A2 shall be selected for redemption at
        the discretion of, or in a manner approved by, the Board.
        Notwithstanding any of the other provisions of this Section 5 of this
        subsection A2, so long as any Preferred A1/A2 Holder remains a
        Significant Holder, the Company shall not be permitted to redeem or
        retire all outstanding shares of Class A2 Preferred Stock, but shall
        instead allow such Significant Holder to remain the holder of one (1)
        share of Class A2 Preferred Stock.

               (d)    On and after any date set for redemption (the "Redemption
        Date") pursuant to this Section 5 of this subsection A2 (unless default
        shall be made by the Company in the payment of the Redemption Price, in
        which event such rights shall be exercisable until such default is
        cured), all rights in respect of the shares of the Class A2 Preferred
        Stock to be redeemed, except the right to receive the Redemption Price,
        shall cease and terminate, and such shares shall no longer be deemed to
        be outstanding, whether or not the certificates representing such shares
        have been received by the Company.

               (e)    Any communication or notice relating to redemption given
        pursuant to this Section 5 of this subsection A2 shall be sent by
        first-class certified mail, return receipt requested, postage prepaid,
        to the Preferred A2 Holders at their respective addresses as the same
        shall appear on the books of the Company, or to the Company at the
        address of its principal, or registered office, as the case may be.

               (f)    At any time on or after the Redemption Date, the Preferred
        A2 Holders shall be entitled to receive the Redemption Price upon actual
        delivery to the Company or its agents of the certificates representing
        the shares of the Class A2 Preferred Stock to be redeemed.

               (g)    Any redemption payments by the Company pursuant to this
        Section 5 of this subsection A2 shall be paid in cash.

               (h)    Any shares of Class A2 Preferred Stock which are redeemed
        or otherwise acquired by the Company shall be canceled and shall not be
        reissued, sold or transferred as Class A2 Preferred Stock and the Board
        shall reduce the number of authorized shares of Class A2 Preferred Stock
        by the number of shares so redeemed or otherwise acquired.

        6.     Maturity Default.

               (a)    The occurrence of any of the following events of default
        shall, at the option of the Requisite Preferred Holders, constitute a
        Maturity Default:

                      (i)    the Company fails to comply in any material respect
               with any of its obligations under any of the Transaction
               Documents or the Fundamental Documents;

                      (ii)   a material default occurs under any mortgage,
               indenture or other instrument under which there may be secured
               or evidenced any indebtedness for money borrowed by the Company
               if the principal amount of such indebtedness aggregates
               $1,000,000 or more; or

                      (iii)  the Company fails to comply with the provisions of
               Section 7.2(g)(iv) of the Purchase Agreement.

<PAGE>   15

               (b)    A default under clauses (a)(i) or (a)(ii) is not a
        Maturity Default until the Company does not cure the default within 30
        days of the Company having Knowledge of such default. When a default is
        cured, it ceases.

               (c)    The Requisite Preferred Holders by notice to the Company
        may waive an existing default or Maturity Default and its consequences.
        When a default or Maturity Default is waived, it ceases.

        7.     Exchange.

               (a)    The Requisite Preferred A2 Holders and the Company may
        agree at any time and from time to time following the Exchange
        Triggering Date to exchange all or any portion of the shares of Class A2
        Preferred Stock outstanding into the Company's Subordinated Debentures
        (the "Notes") to be issued substantially in the form attached as Exhibit
        D to the Purchase Agreement in the amount of $1,000 principal amount of
        Notes for each $1,000 of Liquidation Value of Class A2 Preferred Stock;
        provided, however, that no such exchange may be consummated unless full
        cumulative dividends (including, without duplication, full cumulative
        dividends pro rata for the elapsed portion of the current dividend
        period) on the Class A2 Preferred Stock to the date of exchange shall
        have been paid. Notes shall be issued only in integral multiples of
        $1,000 at the time of exchange. If any additional amounts ("Fractional
        Principal Amounts") would otherwise be issuable to any holders of
        Preferred Stock, then the Company shall, in lieu of issuing a Fractional
        Principal Amount therefor, pay in full payment of the Company's
        obligation with respect to such Fractional Principal Amount, to each
        Preferred A2 Holder an amount in cash equal to such Fractional Principal
        Amount. Any and all exchange rights set forth in this Section 7 of this
        subsection A2 shall be deemed to be a right of redemption. In the event
        that the Company exercises its option to exchange any portion of the
        outstanding shares of Class A2 Preferred Stock into Notes pursuant to
        this Section 7 of this subsection A2, such shares to be exchanged shall
        be selected for exchange at the discretion of, or in a manner approved
        by, the Board. Notwithstanding any of the other provisions of this
        Section 7 of this subsection A2, so long as any Preferred A2 Holder
        remains a Significant Holder, the Company shall not be permitted to
        exchange all outstanding shares of Class A2 Preferred Stock, but shall
        instead allow such Significant Holder to remain the holder of one (1)
        share of Class A2 Preferred Stock.

               (b)    Any exchange pursuant to this Section 7 of this Subsection
        A2 shall be made upon not less than 30 days' notice prior to the date
        fixed for exchange (the "Exchange Date"). The notice given shall state
        that, upon surrender of their certificate or certificates to the
        Company, the holders of Class A2 Preferred Stock will receive Notes in
        the amount set forth in Section 7(a) of this subsection A2 above and
        that, at the close of business on the Exchange Date, all rights of the
        holders with respect to such shares so called for exchange shall cease,
        except the right to receive the Notes in the amount set forth in Section
        7(a) of this subsection A2. Except as may be otherwise required by
        applicable law, the form of the Notes may only be amended or
        supplemented before the first Exchange Date which occurs with the
        affirmative vote or consent of the Requisite Preferred A2 Holders. On or
        after such first Exchange Date, the Notes may only be amended or
        supplemented as provided in the Notes. The Company will cause the Notes
        to be authenticated on the Exchange Date, and the Company will pay
        interest on the Notes at the rate and on the dates specified in the
        Notes from and after the relevant Exchange Date.

        holders of Junior Stock by reason of their ownership thereof, an amount
        equal to the Liquidation Value per share of Class B1 Preferred Stock. If
        upon any such Liquidation of the Company the remaining assets of the
        Company available for distribution to its stockholders shall be
        insufficient to pay the holders of shares of Class B1 Preferred Stock
        the full amount to which they shall be entitled, the holders of shares
        of Class B1 Preferred Stock and the holders of shares of Class A1
        Preferred Stock, Class A2 Preferred Stock, Class C1 Preferred Stock,
        Class D Preferred Stock, Class E Preferred Stock and any other class or
        series of stock ranking on liquidation on a parity with the Class B1
        Preferred Stock shall share ratably in any distribution of the remaining
        assets and funds of the Company in proportion to the respective amounts
        which would otherwise be payable in respect of the shares held by them
        upon such distribution if all amounts payable on or with respect to such
        shares were paid in full.

               (b)    The merger or consolidation of the Company into or with
        another corporation which results in the exchange of outstanding shares
        of the Company for securities or other consideration issued or paid or
        caused to be issued or paid by such other corporation or an affiliate
        thereof (except if such merger or consolidation does not result in the
        transfer of more than 50 percent of the voting securities of the
        Company), or the sale of all or substantially all the assets of the
        Company, shall be deemed to be a Liquidation of the Company for purposes
        of this Section 3 of this subsection B, unless the Requisite Preferred
        B1 Holders vote otherwise. The amount deemed distributed to the holders
        of Class B1 Preferred Stock upon any such merger or consolidation shall
        be the cash or the value of the property, rights and/or securities
        distributed to such holders by the acquiring person, firm or other
        entity. The value of such property, rights or other securities shall be
        determined in good faith by the Board.

        4.     Voting Rights.

               (a)    Except as required by law and pursuant to paragraphs (b),
        (c) and (d) below, the Preferred B1 Holders shall not be entitled to
        vote.

               (b)    The Company shall not, without the affirmative consent or
        approval of the Requisite Preferred B1 Holders:

                      (i)    in any manner authorize, issue or sell any shares
               of Class B1 Preferred Stock other than as contemplated by the
               Purchase Agreement, the Preferred Shareholder Agreement or this
               Designations of Preferred Stock;

                      (ii)   reclassify, cancel or in any manner alter or change
               the designations, preferences, privileges or relative, optional
               or other special rights, or the qualifications, limitations or
               restrictions thereof, of the Class B1 Preferred Stock;

                      (iii)  amend, repeal or modify any provision of this
               subsection B of this Designations of Preferred Stock; or

                      (iv)   amend, repeal or modify any provision of the
               Certificate of Incorporation or By-laws in a manner that would
               adversely affect the preferences, privileges or rights of the
               Preferred B1 Holders.

               (c)

                      (i)    The Company hereby covenants that the Requisite
               Preferred B1 Holders shall have the right to have that number of
               representatives (each such representative, an "Observer")
               determined as hereinafter provided present at all meetings of the
               Board. Such right shall from


                                      -18-

               time to time be exercisable by delivery to the Company of written
               notice from the Requisite Preferred B1 Holders specifying the
               names of such Observers. The number of Observers shall at all
               times and from time to time be equal to that number of nominees
               to the Board that the Preferred B1 Holders are then entitled to
               designate less the number of such nominees as are then members of
               the Board.

                      (ii)   The Company will give each Observer reasonable
               prior notice (it being agreed that the same prior notice given to
               the Board shall be deemed reasonable prior notice) in any manner
               permitted in the Company's By-laws for notices to directors of
               the time and place of any proposed meeting of the Board, such
               notice in all cases to include true and complete copies of all
               documents furnished to any director in connection with such
               meeting. Each such Observer will be entitled to be present in
               person as an observer at any such meeting or, if a meeting is
               held by telephone conference, to participate therein for the
               purpose of listening thereto.

                      (iii)  The Company will deliver to each Observer copies of
               all papers which may be distributed from time to time to the
               directors of the Company at such time as such papers are so
               distributed to them, including copies of any written consent.

               (d)    The Company shall not, without the affirmative consent or
        approval of the Requisite Preferred Holders:

                      (ix)   authorize for issuance, issue, sell, deliver or
               agree or commit to issue, sell or deliver (whether through the
               issuance or granting of options, warrants or exchangeable
               Securities, commitments, subscriptions, rights to purchase or
               otherwise) any shares of capital stock or any other Securities of
               the Company or any Subsidiary, or amend any of the terms of any
               such capital stock or other Securities;

               capital stock, declare, set aside or pay any dividend (other than
               dividends on the Preferred Stock) or other distribution (whether
               in cash, stock or property or any combination thereof) in respect
               of its capital stock, or redeem or otherwise acquire any capital

               liable (whether directly, contingently or otherwise) for the
               obligations of any other Person; and

                      (xii)  except in the ordinary course of business and
               consistent with past practice, make any loans, advances or
               capital contributions to, or investments in, any other Person.

        5.     Redemption.

               (a)    Subject to the Company having funds legally available for
        such purpose, the Company, on the Maturity Date, shall have the option
        of redeeming all the shares of outstanding Class B1 Preferred Stock for
        cash as described in Sections 5(d) - (h) below. If the Company does not
        redeem such shares on the Maturity Date, the Company shall pay full
        cumulative dividends (including, without duplication, full cumulative
        dividends pro rata for the elapsed portion of the current dividend
        period) on the Class B1 Preferred Stock to the Maturity Date and,
        immediately thereafter, each share of Class B1 Preferred Stock shall
        automatically be converted into one share of Class D Preferred Stock.
        The per share redemption price at which shares of Class B1 Preferred
        Stock are to be redeemed pursuant to this Section 5(a) of this
        subsection B1 shall be equal to the Liquidation Value (the "Redemption
        Price").

               (b)    In the event the Company or any of its Subsidiaries
        consummates a public or private offering for cash of capital stock or
        other equity interests, the Company shall be required to apply 50% of
        the Net Proceeds of such offering toward the redemption of shares of
        Preferred Stock (other than Voting Preferred Stock), on a pro rata basis
        (determined on the basis of the number of shares of Preferred Stock
        (other than Voting Preferred Stock), held by such holder over the total
        number of shares of Preferred Stock (other than Voting Preferred Stock)
        outstanding) from the Holders of Preferred Stock at the Redemption
        Price.

               (c)    In addition to the Company's obligations as set forth in
        Sections 5(a) and (b) of this subsection B, the Company shall have the
        option to redeem a minimum of $1 million of Original Cost of Class B1
        Preferred Stock and integral multiples of $100,000 thereafter at the
        Liquidation Value thereof. Any shares to be redeemed pursuant to this
        Section 5(c) of this subsection B shall be selected for redemption at
        the discretion of, or in a manner approved by, the Board.
        Notwithstanding any of the other provisions of this Section 5 of this
        subsection B, so long as any Preferred B1 Holder remains a Significant
        Holder, the Company shall not be permitted to redeem or retire all
        outstanding shares of Class B1 Preferred Stock, but shall instead allow
        such Significant Holder to remain the holder of one (1) share of Class
        B1 Preferred Stock.

               (d)    On and after any date set for redemption (the "Redemption
        Date") pursuant to this Section 5 of this subsection B (unless default
        shall be made by the Company in the payment of the Redemption Price, in
        which event such rights shall be exercisable until such default is
        cured), all rights in respect of the shares of the Class B1 Preferred
        Stock to be redeemed, except the right to receive the Redemption Price,
        shall cease and terminate, and such shares shall no longer be deemed to
        be outstanding, whether or not the certificates representing such shares
        have been received by the Company.

               (e)    Any communication or notice relating to redemption given
        pursuant to this Section 5 of this subsection B shall be sent by
        first-class certified mail, return receipt requested, postage prepaid,
        to the Preferred B1 Holders, at their respective addresses as the same
        shall appear on the books of the Company, or to the Company at the
        address of its principal, or registered office, as the case may be.


                                      -20-
<PAGE>   21

               (f)    At any time on or after the Redemption Date, the Preferred
        B1 Holders shall be entitled to receive the Redemption Price upon actual
        delivery to the Company or its agents of the certificates representing
        the shares of the Class B1 Preferred Stock to be redeemed.

               (g)    Any redemption payments by the Company pursuant to this
        Section 5 of this subsection B shall be paid in cash.

               (h)    Any shares of Class B1 Preferred Stock which are redeemed
        or otherwise acquired by the Company shall be canceled and shall not be
        reissued, sold or transferred as Class B1 Preferred Stock and the Board
        shall reduce the number of authorized shares of Class B1 Preferred stock
        by the number of shares so redeemed or otherwise acquired.

6.      Maturity Default.

               (a)    The occurrence of any of the following events of default
        shall, at the option of the Requisite Preferred Holders, constitute a
        Maturity Default:

                      (i)    the Company fails to comply in any material respect
               with any of its obligations under any of the Transaction
               Documents or the Fundamental Documents;

                      (ii)   a material default occurs under any mortgage,
               indenture or other instrument under which there may be secured
               or evidenced any indebtedness for money borrowed by the Company
               if the principal amount of such indebtedness aggregates
               $1,000,000 or more; or

                      (iii)  the Company fails to comply with the provisions of
               Section 7.2(g)(iv) of the Purchase Agreement.

               (b)    A default under clauses (a)(i) or (a)(ii) is not a
        Maturity Default until the Company does not cure the default within 30
        days of the Company having Knowledge of such default. When a default is
        cured, it ceases.

               (c)    The Requisite Preferred Holders by notice to the Company
        may waive an existing default or Maturity Default and its consequences.
        When a default or Maturity Default is waived, it ceases.

        7.     Exchange.

               (a)    The Requisite Preferred B1 Holders and the Company may
        agree at any time and from time to time following the Exchange
        Triggering Date to exchange all or any portion of the shares of Class B1
        Preferred Stock outstanding into the Company's Subordinated Debentures
        (the "Notes") to be issued substantially in the form attached as Exhibit
        D to the Purchase Agreement in the amount of $1,000 principal amount of
        Notes for each $1,000 of Liquidation Value of Class B1 Preferred Stock;
        provided, however, that no such exchange may be consummated unless full
        cumulative dividends (including, without duplication, full cumulative
        dividends pro rata for the elapsed portion of the current dividend
        period) on the Class B1 Preferred Stock to the date of exchange shall
        have been paid. Notes shall be issued only in integral multiples of
        $1,000 at the time of exchange. If any additional amounts ("Fractional
        Principal Amounts") would otherwise be issuable to any holders of
        Preferred Stock, then the Company shall, in lieu of issuing a Fractional
        Principal Amount therefor, pay in full payment of the Company's
        obligation with respect to such Fractional Principal Amount, to each
        Preferred B1 Holder an amount in cash equal to such Fractional Principal
        Amount. Any and all exchange rights set forth in this Section 7 of this
        subsection shall be deemed to be a right of redemption. In the event
        that the Company exercises its option to exchange any portion of the
        outstanding shares of Class B1 Preferred Stock into Notes pursuant to
        this Section 7 of this subsection B, such shares to be exchanged shall
        be selected for exchange at the discretion of, or in a manner approved
        by, the Board. Notwithstanding any of the other provisions of this
        Section 7 of this subsection B, so long as any Preferred B1 Holder
        remains a Significant Holder, the Company shall not be


                                      -21-
<PAGE>   22

        permitted to exchange all outstanding shares of Class B1 Preferred
        Stock, but shall instead allow such Significant Holder to remain the
        holder of one (1) share of Class B1 Preferred Stock.

               (b)    Any exchange pursuant to this Section 7 of this Subsection
        B shall be made upon not less than 30 days' notice prior to the date
        fixed for exchange (the "Exchange Date"). The notice given shall state
        that, upon surrender of their certificate or certificates to the
        Company, the holders of Class B1 Preferred Stock will receive Notes in
        the amount set forth in Section 7(a) of this subsection B and that, at
        the close of business on the Exchange Date, all rights of the holders
        with respect to such shares so called for exchange shall cease, except
        the right to receive the Notes in the amount set forth in Section 7(a)
        of this subsection B. Except as may be otherwise required by applicable
        law, the form of the Notes may only be amended or supplemented before
        the first Exchange Date which occurs with the affirmative vote or
        consent of the Requisite Preferred B1 Holders. On or after such first
        Exchange Date, the Notes may only be amended or supplemented as provided
        in the Notes. The Company will cause the Notes to be authenticated on
        the Exchange Date, and the Company will pay interest on the Notes at the
        rate and on the dates specified in the Notes from and after the relevant
        Exchange Date.

        (subject to appropriate adjustments in the event of any stock dividend,
        stock split, combination or other similar recapitalization affecting
        such shares) per share per annum, and no more, payable in preference and
        priority to any payment of any cash dividend on Common Stock or any
        other shares of capital stock of the Company other than the Class A1
        Preferred Stock, Class A2 Preferred Stock, Class B1 Preferred Stock,
        Class D Preferred Stock and Class E Preferred Stock (which shall rank on
        a par with the Class C1 Preferred Stock) or other class or series of
        stock ranking on a par with, or senior to the Class C1 Preferred Stock
        in respect of dividends (such Common Stock and other inferior stock
        being collectively referred to as "Junior Stock"), when and as declared
        by the Board.

               (b)    Such dividends shall accrue with respect to each share of
        Class C1 Preferred Stock from the date on which such share is issued and
        outstanding and thereafter shall be deemed to accrue from day to day
        whether or not earned or declared and whether or not there exists
        profits, surplus or other funds legally available for the payment of
        dividends, and shall be cumulative so that if such dividends on the
        Class C1 Preferred Stock shall not have been paid, or declared and set
        apart for payment, the deficiency shall be fully paid or declared and
        set apart for payment before any dividend shall be paid or declared or
        set apart for any Junior Stock and before any purchase or acquisition of
        any Junior Stock is made by the Company, except the repurchase of Junior
        Stock from employees of the Company upon termination of employment or as
        otherwise approved by the Requisite Preferred C1 Holders.

               (c)    Dividends shall be payable in cash, quarterly in arrears.
        To the extent dividends are not paid on each September 30, December 31,
        March 31 and June 30 (each a "Dividend Reference Date"), all dividends
        which have accrued on each share of Class C1 Preferred Stock during the
        three-month period (or shorter period in the case of the first or last
        period) ending on each Dividend Reference Date will be added to the
        Liquidation Value of such share and will remain a part thereof until
        such dividends are paid in full in cash. Each dividend paid in cash
        shall be mailed to the holders of record of the Class C1 Preferred Stock
        as their names and addresses appear on the share register of the Company
        or at the office of the transfer agent on the corresponding dividend
        payment date.

        3.     Liquidation.

               (a)    In the event of any Liquidation of the Company, the
        Preferred C1 Holders shall be entitled to be paid out of the assets of
        the Company legally available for distribution to its stockholders,
        after and subject to the payment in full of all amounts required to be
        distributed to the holders of Voting Preferred Stock and any other class
        or series of stock of the Company ranking on liquidation prior and in
        preference to the Class C1 Preferred Stock (collectively referred to as
        "Senior Preferred Stock"), but before any payment shall be made to the
        holders of Junior Stock by reason of their ownership thereof, an amount
        equal to the Liquidation Value per share of Class C1 Preferred Stock. If
        upon any such Liquidation of the Company the remaining assets of the
        Company available for distribution to its stockholders shall be
        insufficient to pay the holders of shares of Class C1 Preferred Stock
        the full amount to which they shall be entitled, the holders of shares
        of Class C1 Preferred Stock and the holders of shares of Class A1
        Preferred Stock, Class A2 Preferred Stock, Class B1 Preferred Stock,
        Class D Preferred Stock, Class E Preferred Stock and any other class or
        series of stock ranking on liquidation on a parity with the Class C1
        Preferred Stock shall share ratably in any distribution of the remaining
        assets and funds of the Company in proportion to the respective amounts
        which would otherwise be payable in respect of the shares held by them
        upon such distribution if all amounts payable on or with respect to such
        shares were paid in full.

               (b)    The merger or consolidation of the Company into or with
        another corporation which results in the exchange of outstanding shares
        of the Company for securities or other consideration issued or paid or
        caused to be issued or paid by such other corporation or an affiliate
        thereof (except if such merger or consolidation does not result in the
        transfer of more than 50 percent of the voting securities of the
        Company), or the sale of all or substantially all the assets of the
        Company, shall be deemed to be a Liquidation of the Company for purposes
        of this Section 3 of this subsection C, unless the Requisite Preferred
        C1 Holders vote otherwise. The amount deemed distributed to the holders
        of Class C1 Preferred Stock upon any such merger or consolidation shall
        be the cash or the value of the property, rights and/or securities
        distributed to such holders by the acquiring person, firm or other
        entity. The value of such property, rights or other securities shall be
        determined in good faith by the Board.

        4.     Voting Rights.

               (a)    Except as required by law and pursuant to paragraphs (b),
        (c) and (d) below, the Preferred C1 Holders shall not be entitled to
        vote.

               (b)    The Company shall not, without the affirmative consent or
        approval of the Requisite Preferred C1 Holders:

                      (i)    in any manner authorize, issue or sell any shares
               of Class C1 Preferred Stock other than as contemplated by the
               Purchase Agreement or this Designations of Preferred Stock;

                      (ii)   reclassify, cancel or in any manner alter or change
               the designations, preferences privileges or relative, optional or
               other special rights, or the qualifications, limitations or
               restrictions thereof, of the Class C1 Preferred Stock;

                      (iii)  amend, repeal or modify any provision of this
               subsection C of this Designations of Preferred Stock; or

                      (iv)   amend, repeal or modify any provision of the
               Certificate of Incorporation or By-laws in a manner that would
               adversely affect the preferences, privileges or rights of the
               Preferred C1 Holders.

               (c)

                      (i)    The Company hereby covenants that the Requisite
               Preferred C1 Holders shall have the right to have that number of
               representatives (each such representative, an "Observer")
               determined as hereinafter provided present at all meetings of the
               Board. Such right shall from time to time be exercisable by
               delivery to the Company of written notice from the Requisite
               Preferred C1 Holders specifying the names of such Observers. The
               number of Observers shall at all times and from time to time be
               equal to that number of nominees to the Board that the Preferred
               C1 Holders are then entitled to designate less the number of such
               nominees as are then members of the Board.

                      (ii)   The Company will give each Observer reasonable
               prior notice (it being agreed that the same prior notice given to
               the Board shall be deemed reasonable prior notice) in any manner
               permitted in the Company's By-laws for notices to directors of
               the time and place of any proposed meeting of the Board, such
               notice in all cases to include true and complete copies of all
               documents furnished to any director in connection with such
               meeting. Each such Observer will be entitled to be present in
               person as an observer at any such meeting or, if a meeting is
               held by telephone conference, to participate therein for the
               purpose of listening thereto.

                      (iii)  The Company will deliver to each Observer copies of
               all papers which may be distributed from time to time to the
               directors of the Company at such time as such papers are so
               distributed to them, including copies of any written consent.

               (d)    The Company shall not, without the affirmative consent or
        approval of the Requisite Preferred Holders:

                      (i)    take any action, or enter into or authorize any
               material agreement or material transaction, other than in the
               ordinary course of business and consistent with past practice;

                      (ii)   agree to acquire the stock or assets of, or
               otherwise agree to any joint venture, licensing arrangement with,

               be expected to result in a Change of Control;

                      (iv)   sell, transfer, convey, assign or otherwise dispose
               of any of its material assets or properties, or spinoff or
               splitoff any material assets, properties or Securities except
               sales of inventory and used, obsolete, worn out or unnecessary
               equipment or fixtures in the ordinary course of business and
               consistent with past practice;

                      (v)    sell, transfer, convey, assign, license or
               otherwise dispose of any significant portion of its Intellectual
               Property Rights;

                      (vi)   except in the ordinary course of business and

               material claims against third parties or material debts owing to
               it, or any material rights which have any material value;

                      (ix)   authorize for issuance, issue, sell, deliver or
               agree or commit to issue, sell or deliver (whether through the
               issuance or granting of options, warrants or exchangeable
               Securities, commitments, subscriptions, rights to purchase or
               otherwise) any shares of capital stock or any other Securities of
               the Company or any Subsidiary, or amend any of the terms of any
               such capital stock or other Securities;

                      (x)    split, combine, or reclassify any shares of its

               dividends on the Preferred Stock) or other distribution (whether
               in cash, stock or property or any combination thereof) in respect
               of its capital stock, or redeem or otherwise acquire any capital
               stock or other Securities of the Company or any Subsidiary;

               obligations of any other Person; and

                      (xii)  except in the ordinary course of business and
               consistent with past practice, make any loans, advances or
               capital contributions to, or investments in, any other Person.

        5.     Redemption.

               (a)    Subject to the Company having funds legally available for
        such purpose, the Company, on the Maturity Date shall have the option of
        redeeming all the shares of outstanding Class C1 Preferred Stock for
        cash as described in Sections 5(d) - (h) below. If the Company does not
        redeem such shares on the Maturity Date, the Company shall pay full
        cumulative dividends (including, without duplication, full cumulative
        dividends pro rata for the elapsed portion of the current dividend
        period) on the Class C1 Preferred Stock to the Maturity Date and,
        immediately thereafter, each share of Class C1 Preferred Stock shall
        automatically be converted into one share of Class D Preferred Stock.
        The per share redemption price at which shares of Class C1 Preferred
        Stock are to be redeemed pursuant to this Section 5(a) of this
        subsection C1 shall be equal to the Liquidation Value (the "Redemption
        Price").

               (b)    In the event the Company or any of its Subsidiaries
        consummates a public or private offering for cash of capital stock or
        other equity interests, the Company shall be required to apply 50% of
        the Net Proceeds of such offering toward the redemption of shares of
        Preferred Stock (other than Voting


                                      -26-
<PAGE>   27

        Preferred Stock), on a pro rata basis (determined on the basis of the
        number of shares of Preferred Stock (other than Voting Preferred Stock),
        held by such holder over the total number of shares of Preferred Stock
        (other than Voting Preferred Stock) outstanding) from the Holders of
        Preferred Stock at the Redemption Price.

               (c)    In addition to the Company's obligations as set forth in
        Sections 5(a) and (b), of this subsection C, the Company shall have the
        option to redeem a minimum of $1 million of Original Cost of Class C1
        Preferred Stock and integral multiples of $100,000 thereafter at the
        Liquidation Value thereof. Any shares to be redeemed pursuant to this
        Section 5(c) of this subsection C shall be selected for redemption at
        the discretion of, or in a manner approved by, the Board.
        Notwithstanding any of the other provisions of this Section 5 of this
        subsection C, so long as any Preferred C1 Holder remains a Significant
        Holder, the Company shall not be permitted to redeem or retire all
        outstanding shares of Class C1 Preferred Stock, but shall instead allow
        such Significant Holder to remain the holder of one (1) share of Class
        C1 Preferred Stock.

               (d)    On and after any date set for redemption (the "Redemption
        Date") pursuant to this Section 5 of this subsection C (unless default
        shall be made by the Company in the payment of the Redemption Price, in
        which event such rights shall be exercisable until such default is
        cured), all rights in respect of the shares of the Class C1 Preferred
        Stock to be redeemed, except the right to receive the Redemption Price,
        shall cease and terminate, and such shares shall no longer be deemed to
        be outstanding, whether or not the certificates representing such shares
        have been received by the Company.

               (e)    Any communication or notice relating to redemption given
        pursuant to this Section 5 of this subsection C shall be sent by
        first-class certified mail, return receipt requested, postage prepaid,
        to the Preferred C1 Holders, at their respective addresses as the same
        shall appear on the books of the Company, or to the Company at the
        address of its principal, or registered office, as the case may be.

               (f)    At any time on or after the Redemption Date, the Preferred
        C1 Holders shall be entitled to receive the Redemption Price upon actual
        delivery to the Company or its agents of the certificates representing
        the shares of the Class C1 Preferred Stock to be redeemed.

               (g)    Any redemption payments by the Company pursuant to this
        Section 5 of this subsection C shall be paid in cash.

               (h)    Any shares of Class C1 Preferred Stock which are redeemed
        or otherwise acquired by the Company shall be canceled and shall not be
        reissued, sold or transferred as Class C1 Preferred Stock and the Board
        shall reduce the number of authorized shares of Class C1 Preferred Stock
        by the number of shares so redeemed or otherwise acquired.

        6.     Maturity Default.

               (a)    The occurrence of any of the following events of default
        shall, at the option of the Requisite Preferred Holders, constitute a
        Maturity Default:

                      (i)    the Company fails to comply in any material respect
               with any of its obligations under any of the Transaction
               Documents or the Fundamental Documents;

                      (ii)   a material default occurs under any mortgage,
               indenture or other instrument under which there may be secured
               or evidenced any indebtedness for money borrowed by the Company
               if the principal amount of such indebtedness aggregates
               $1,000,000 or more; or

                      (iii)  the Company fails to comply with the provisions of
               Section 7.2(g)(iv) of the Purchase Agreement.


                                      -27-
<PAGE>   28

               (b)    A default under clauses (a)(i) or (a)(ii) is not a
        Maturity Default until the Company does not cure the default within 30
        days of the Company having Knowledge of such default. When a default is
        cured, it ceases.

               (c)    The Requisite Preferred Holders by notice to the Company
        may waive an existing default or Maturity Default and its consequences.
        When a default or Maturity Default is waived, it ceases.

        7.     Exchange.

               (a)    The Requisite Preferred C1 Holders and the Company may
        agree at any time and from time to time following the Exchange
        Triggering Date to exchange all or any portion of the shares of Class C1
        Preferred Stock outstanding into the Company's Subordinated Debentures
        (the "Notes") to be issued substantially in the form attached as Exhibit
        D to the Purchase Agreement, in the amount of $1,000 principal amount of
        Notes for each $1,000 of Liquidation Value of Class C1 Preferred Stock;
        provided, however, that no such exchange may be consummated unless full
        cumulative dividends (including, without duplication, full cumulative
        dividends pro rata for the elapsed portion of the current dividend
        period) on the Class C1 Preferred Stock to the date of exchange shall
        have been paid. Notes shall be issued only in integral multiples of
        $1,000 at the time of exchange. If any additional amounts ("Fractional
        Principal Amounts") would otherwise be issuable to any holders of
        Preferred Stock, then the Company shall, in lieu of issuing a Fractional
        Principal Amount therefor, pay in full payment of the Company's
        obligation with respect to such Fractional Principal Amount, to each
        Preferred C1 Holder an amount in cash equal to such Fractional Principal
        Amount. Any and all exchange rights set forth in this Section 7 of this
        subsection C shall be deemed to be a right of redemption. In the event
        that the Company exercises its option to exchange any portion of the
        outstanding shares of Class C1 Preferred Stock into Notes pursuant to
        this Section 7 of this subsection C, such shares to be exchanged shall
        be selected for exchange at the discretion of, or in a manner approved
        by, the Board. Notwithstanding any of the other provisions of this
        Section 7 of this subsection C, so long as any Preferred C1 Holder

               delivery to the Company of written notice from the Requisite
               Preferred D Holders specifying the names of such Observers. The
               number of Observers shall at all times and from time to time be
               equal to that number of nominees to the Board that the Preferred
               D Holders are then entitled to designate less the number of such
               nominees as are then members of the Board.

                      (ii)   The Company will give each Observer reasonable
               prior notice (it being agreed that the same prior notice given to

               permitted in the Company's By-laws for notices to directors of
               the time and place of any proposed meeting of the Board, such

               documents furnished to any director in connection with such
               meeting. Each such Observer will be entitled to be present in

               held by telephone conference, to participate therein for the
               purpose of listening thereto.

                      (iii)  The Company will deliver to each Observer copies of
               all papers which may be distributed from time to time to the
               directors of the Company at such time as such papers are so
               distributed to them, including copies of any written consent.

               Section 7.2(g)(iv) of the Purchase Agreement.

               (b)    A default under clauses (a)(i) or (a)(ii) is not a
        Maturity Default until the Company does not cure the default within 30
        days of the Company having Knowledge of such default. When a default is
        cured, it ceases.

               (c)    The Requisite Preferred Holders by notice to the Company
        may waive an existing default or Maturity Default and its consequences.

        7.     Exchange.

               (a)    The Requisite Preferred D Holders and the Company may
        agree at any time and from time to time following the Exchange
        Triggering Date to exchange all or any portion of the shares of Class D
        Preferred Stock outstanding into the Company's Subordinated Debentures
        (the "Notes") to be issued substantially in the form attached as Exhibit
        D to the Purchase Agreement in the amount of $1,000 principal amount of
        Notes for each $1,000 of Liquidation Value of Class D Preferred Stock;
        provided, however, that no such exchange may be consummated unless full
        cumulative dividends (including, without duplication, full cumulative
        dividends pro rata for the elapsed portion of the current dividend
        period) on the Class D Preferred Stock to the date of exchange shall
        have been paid. Notes shall be issued only in integral multiples of
        $1,000 at the time of exchange. If any additional amounts ("Fractional
        Principal Amounts") would otherwise be issuable to any holders of
        Preferred Stock, then the Company shall, in lieu of issuing a Fractional
        Principal Amount therefor, pay in full payment of the Company's
        obligation with respect to such Fractional Principal Amount, to each
        Preferred D Holder an amount in cash equal to such Fractional Principal
        Amount. Any and all exchange rights set forth in this Section 7 of this
        subsection D shall be deemed to be a right of redemption. In the event
        that the Company exercises its option to exchange any portion of the
        outstanding shares of Class D Preferred Stock into Notes pursuant to
        this Section 7 of this subsection D, such shares to be exchanged shall
        be selected for exchange at the discretion of, or in a manner approved
        by, the Board. Notwithstanding any of the other provisions of this
        Section 7 of this subsection D, so long as any Preferred D Holder
        remains a Significant Holder, the Company shall not be permitted to
        exchange all outstanding shares of Class D Preferred Stock, but shall
        instead allow such Significant Holder to remain the holder of one (1)
        share of Class D Preferred Stock.

               (b)    Any exchange pursuant to this Section 7 of this Subsection
        D shall be made upon not less than 30 days' notice prior to the date
        fixed for exchange (the "Exchange Date"). The notice given shall state
        that, upon surrender of their certificate or certificates to the
        Company, the holders of Class D Preferred Stock will receive Notes in
        the amount set forth in Section 7(a) of this subsection D above and
        that, at the close of business on the Exchange Date, all rights of the
        holders with respect to such shares so called for exchange shall cease,
        except the right to receive the Notes in the amount set forth in Section
        7(a) of this subsection D. Except as may be otherwise required by
        applicable law, the form of the Notes may only be amended or
        supplemented before the first Exchange Date which occurs with the
        affirmative vote or consent of the Requisite Preferred D Holders. On or
        after such first Exchange Date, the Notes may only be amended or
        supplemented as provided in the Notes. The Company will cause the Notes
        to be authenticated on the Exchange Date, and the Company will pay
        interest on the Notes at the rate and on the dates specified in Notes
        from and after the relevant Exchange Date.

        (subject to appropriate adjustments in the event of any stock dividend,
        stock split, combination or other similar recapitalization affecting
        such shares) per share per annum, and no more, payable in preference and

        Preferred Stock, Class A2 Preferred Stock, Class B1 Preferred Stock,

               (b)    Such dividends shall accrue with respect to each share of
        Class E Preferred Stock from the date on which such share is issued and

        whether or not earned or declared and whether or not there exists
        profits, surplus or other funds legally available for the payment of
        dividends, and shall be cumulative so that if such dividends on the
        Class E Preferred Stock shall not have been paid, or declared and set
        apart for payment, the deficiency shall be fully paid or declared and

        or at the office of the transfer agent on the corresponding dividend

        after and subject to the payment in full of all amounts required to be
        distributed to the holders of Voting Preferred

        Stock and any other class or series of stock of the Company ranking on
        liquidation prior and in preference to the Class E Preferred Stock
        (collectively referred to as "Senior Preferred Stock"), but before any
        payment shall be made to the holders of Junior Stock by reason of their
        ownership thereof, an amount equal to the Liquidation Value per share of
        Class E Preferred Stock. If upon any such Liquidation of the Company the
        remaining assets of the Company available for distribution to its
        stockholders shall be insufficient to pay the holders of shares of Class
        E Preferred Stock the full amount to which they shall be entitled, the

        of Class A1 Preferred Stock, Class A2 Preferred Stock, Class B1
        Preferred Stock, Class C1 Preferred Stock, Class D Preferred Stock and
        any other class or series of stock ranking on liquidation on a parity
        with the Class E Preferred Stock shall share ratably in any distribution
        of the remaining assets and funds of the Company in proportion to the
        respective amounts which would otherwise be payable in respect of the
        shares held by them upon such distribution if all amounts payable on or
        with respect to such shares were paid in full.

        another corporation which results in the exchange of outstanding shares
        of the Company for securities or other consideration issued or paid or
        caused to be issued or paid by such other corporation or an affiliate
        thereof (except if such merger or consolidation does not result in the
        transfer of more than 50 percent of the voting securities of the
        Company), or the sale of all or substantially all of the assets of the
        Company, shall be deemed to be a Liquidation of the Company for purposes
        of this Section 3 of this Subsection E, unless the Requisite Preferred E
        Holders vote otherwise. The amount deemed distributed to the holders of
        Class E Preferred Stock upon any such merger or consolidation shall be
        the cash or the value of the property, rights and/or securities
        distributed to such holders by the acquiring person, firm or other
        entity. The value of such property, rights or other securities shall be
        determined in good faith by the Board.

4.      Voting Rights.

               (a)    Except as required by law and pursuant to paragraphs (b),
        (c) and (d) below, the Preferred E Holders shall not be entitled to
        vote.

               (b)    The Company shall not, without the affirmative consent or
        approval of the Requisite Preferred E Holders:

                      (i)    in any manner authorize, issue or sell any shares
               of Class E Preferred Stock other than as contemplated by the
               Purchase Agreement or this Determination of Preferred Stock;

                      (ii)   reclassify, cancel or in any manner alter or change
               the designations, privileges or relative, optional or other
               special rights, or the qualifications, limitations or
               restrictions thereof, of the Class E Preferred Stock;

                      (iii)  amend, repeal or modify any provision of this
               Determination of Preferred Stock; or

                      (iv)   amend, repeal or modify any provision of the
               Certificate of Incorporation or By-laws in a manner that would
               adversely affect the preferences, privileges or rights of the
               Preferred E Holders.

               (c)    (i)    The Company hereby covenants that the Requisite
               Preferred E Holders shall have the right to have that number of
               representatives (each such representative, an "Observer")
               determined as hereinafter provided present at all meetings of the
               Board. Such right shall from time to time be exercisable by
               delivery to the Company of written notice from the Requisite
               Preferred E Holders specifying the names of such Observers. The
               number of Observers shall at all times and from time to time be
               equal to that number of nominees to the Board that the Preferred
               E Holders are then entitled to designate less the number of such
               nominees as are then members of the Board.

                      (ii)   The Company will give each Observer reasonable
               prior notice (it being agreed that the same prior notice given to
               the Board shall be deemed reasonable prior notice) in any manner

               the time and place of any proposed meeting of the Board, such
               notice in all cases to include true and complete copies of all
               documents furnished to any director in connection with such
               meeting. Each such Observer will be entitled to be present in

               all papers which may be distributed from time to time to the
               directors of the Company at such time as such papers are so
               distributed to them, including copies of any written consent.

               (d)    The Company shall not, without the affirmative consent or
        approval of the Requisite Preferred Holders;

                      (i)    take any action, or enter into or authorize any

        equal to the Liquidation Value (the "Redemption Price").

               (b)    In the event the Company or any of its Subsidiaries
        consummates a public or private offering for cash of capital stock or
        other equity interests, the Company shall be required to apply 50% of
        the Net Proceeds of such offering toward the redemption of shares of
        Preferred Stock (other than Voting Preferred Stock), on a pro rata basis
        (determined on the basis of the number of shares of Preferred Stock
        (other than Voting Preferred Stock), held by such holder over the total
        number of shares of Preferred Stock (other than Voting Preferred Stock)
        outstanding) from the Holders of Preferred Stock at the Redemption
        Price.

        Sections 5(a) and 5(b) of this Subsection E, the Company shall have the
        option to redeem a minimum of $1 million of Original Cost of Class E
        Preferred Stock and integral multiples of $100,000 thereafter at the
        Liquidation Value thereof. Any shares to be redeemed pursuant to this
        Section 5(c) of this Subsection E shall be selected for redemption at
        the discretion of, or in a manner approved by, the Board.

               (d)    On and after any date set for redemption (the "Redemption
        Date") pursuant to this Section 5 of this Subsection E (unless default
        shall be made by the Company in the payment of the Redemption Price, in
        which event such rights shall be exercisable until such default is
        cured), all rights in respect of the shares of the Class E Preferred
        Stock to be redeemed, except the right to receive the Redemption Price,
        shall cease and terminate, and such shares shall no longer be deemed to
        be outstanding, whether or not the certificates representing such shares
        have been received by the Company.

               (e)    Any communication or notice relating to redemption given
        pursuant to this Section 5 of this Subsection E shall be sent by
        first-class certified mail, return receipt requested, postage prepaid,
        to the Preferred E Holders at their respective addresses as the same

        address of its principal, or registered office, as the case may be.

               (f)    At any time on or after the Redemption Date, the Preferred
        E Holders shall be entitled to receive the Redemption Price upon actual
        delivery to the Company or its agents of the certificates representing
        the shares of the Class E Preferred Stock to be redeemed.

               (g)    Any redemption payments by the Company pursuant to this
        Section 5 of this Subsection E shall be paid in cash.

               (h)    Any shares of Class E Preferred Stock which are redeemed
        or otherwise acquired by the Company shall be canceled and shall not be
        reissued, sold or transferred as Class E Preferred Stock and the Board
        shall reduce the number of authorized shares of Class E Preferred Stock
        by the number of shares so redeemed or otherwise acquired.

        6.     Maturity Default.

               (a)    The occurrence of any of the following events of default
        shall, at the option of the Requisite Preferred Holders, constitute a
        Maturity Default:

                      (i)    the Company fails to comply in any material respect
               with any of its obligations under any of the Transaction
               Documents or the Fundamental Documents;

                      (ii)   a material default occurs under any mortgage,
               indenture or other instrument under which there may be secured
               or evidenced any indebtedness for money borrowed by the Company
               if the principal amount of such indebtedness aggregates
               $1,000,000 or more; or

                      (iii)  the Company fails to comply with the provisions of
               Section 7.2(g)(iv) of the Purchase Agreement.

               (b)    A default under clauses (a)(i) or (a)(ii) is not a
        Maturity Default until the Company does not cure the default within 30
        days of the Company having Knowledge of such default. When a default is
        cured, it ceases.

               (c)    The Requisite Preferred Holders by notice to the Company
        may waive an existing default or Maturity Default and its consequences.
        When a default or Maturity Default is waived, it ceases.

        7.     Exchange.

               (a)    The Requisite Preferred E Holders and the Company may
        agree at any time and from time to time following the Exchange
        Triggering Date to exchange all or any portion of the shares of Class E
        Preferred Stock outstanding into the Company's Subordinated Debentures
        (the "Notes") to be issued substantially in the form attached to the
        Purchase Agreement as Exhibit D, in the amount of $1,000 principal
        amount of Notes for each $1,000 of Liquidation Value of Class E
        Preferred Stock; provided, however, that no such exchange may be
        consummated unless full cumulative dividends (including, without
        duplication, full cumulative dividends pro rata for the elapsed portion
        of the current dividend period) on the Class E Preferred Stock to the
        date of exchange shall have been paid. Notes shall be issued only in
        integral multiples of $1,000 at the time of exchange. If any additional
        amounts ("Fractional Principal Amounts") would otherwise be issuable to
        any holders of Preferred Stock, then the Company shall, in lieu of
        issuing a Fractional Principal Amount therefor, pay in full payment of
        the Company's obligation with respect to such Fractional Principal
        Amount therefor, pay in full payment of the Company's obligation with
        respect to such Fractional Principal Amount, to each Preferred E Holder
        an amount in cash equal to the Fractional Principal Amount. Any and all
        exchange rights set forth in this Section 7 of this Subsection E shall
        be deemed to be a right of redemption. In the event that the Company
        exercises its option to exchange any portion of the outstanding shares
        of Class E Preferred Stock into Notes pursuant to this Section 7 of this
        Subsection E, such shares to be exchanged shall be selected for exchange
        at the discretion of, or in a manner approved by, the Board.

               (b)    Any exchange pursuant to this Section 7 of this Subsection
        E shall be made upon not less than 30 days' notice prior to the date
        fixed for exchange (the "Exchange Date"). The notice given shall state
        that, upon surrender of their certificate or certificates to the
        Company, the holders of Class E Preferred Stock will receive Notes in
        the amount set forth in Section 7(a) of this Subsection E above and
        that, at the close of business on the Exchange Date, all rights of the
        holders with respect to such shares so called for exchange shall cease,
        except the right to receive the Notes in the amount set forth in Section
        7(a) of this Subsection E. Except as may be otherwise required by
        applicable law, the form of the Notes may only be amended or
        supplemented before the first Exchange Date which occurs with the
        affirmative vote or consent of the Requisite Preferred E Holders. On or
        after such first Exchange Date, the Notes may only be amended or
        supplemented as provided in the Notes. The Company will cause the Notes
        to be authenticated on the Exchange Date, and the Company will pay
        interest on the Notes at the rate and on the dates specified in the
        Notes from and after the relevant Exchange Date.

evidencing shares of Voting Preferred Stock, and in the case of any such loss,
theft or destruction, upon receipt of indemnity reasonably satisfactory to the
Company (provided that if the holder is an institutional investor, its own
