               (vi) (the "Additional Undesignated Preferred Stock")
               (collectively, the "Undesignated Preferred Stock"). Subject to
               any limitations set forth elsewhere in this Certificate of
               Incorporation, the shares of Undesignated Preferred Stock may be
               issued from time to time in one or more series. Subject to any
               limitations set forth elsewhere in this Certificate of
               Incorporation, the Board of Directors is hereby authorized, by
               adopting appropriate resolutions and causing one or more
               certificates of amendment to be signed, verified and delivered in
               accordance with the DGCL, to establish from time to time the
               number of shares to be included in such series, and to fix the
               powers, preferences and rights of, and the qualifications,
               limitations and restrictions granted to and imposed upon such
               Undesignated Preferred Stock. Such powers, preferences and rights
               of, and the qualifications, limitations and restrictions granted
               to and imposed upon such Undesignated Preferred Stock may
               include, but are not limited to, the fixing or alteration of the
               dividend rights, dividend rate, conversion rights, exchange
               rights, voting rights, rights and terms of redemption (including
               sinking fund provisions), the redemption price or prices, and the
               liquidation preferences of any wholly unissued series of shares
               of Undesignated Preferred Stock, or any of them. In accordance

                                       -3-



               with the authority hereby granted, the Board may increase or
               decrease the number of shares of any series of preferred stock,
               whether or not such preferred stock then constitutes Undesignated
               Preferred Stock, subsequent to the issuance of shares of that
               series; provided that any such increase shall be no greater than
               the total number of authorized shares of Undesignated Preferred
               Stock at such time, and no such decrease shall result in the
               number of authorized shares of such series being fewer than the
               number then outstanding. In case the number of shares of any
               series of preferred stock, other than Undesignated Preferred
               Stock, shall be so decreased, the shares constituting such
               decrease shall become Additional Undesignated Preferred Stock.
               Any shares of Series A Preferred Stock, Series B Preferred Stock,
               Series C Preferred Stock, Series D Preferred Stock or any Future
               Designated Preferred Series that were issued but, thereafter, are
               no longer outstanding shall not resume the status of authorized
               and unissued shares of such series, but shall instead become
               authorized and unissued shares of Additional Undesignated
               Preferred Stock. Except as may otherwise be required by law or
               this Certificate of Incorporation, the terms of any series of
               Undesignated Preferred Stock may be amended without the consent
               of the holders of any other series of the Corporation's preferred
               stock, or Common Stock.

          Section 3. Preferred Stock. The relative powers, preferences and
rights of, and the qualifications, limitations and restrictions granted to and
imposed upon, certain of the preferred stock are as set forth in Articles V, VI,
VII and VIII.

          Section 4. Reverse Stock Split. (a) Simultaneously with the effective
date of a registration statement filed with the Securities and Exchange
Commission in respect of a Qualified Public Offering (the "Effective Date"),
each share of the Corporation's Common Stock issued and outstanding immediately
prior to the Effective Date (the "Old Common Stock") shall automatically and
without any action on the part of the holder thereof be reclassified as and
changed into 0.2841 of a share of the Corporation's common stock, par value
$.001 per share (the "New Common Stock"), subject to the treatment of fractional
share interests as described below. Each holder of a certificate or certificates
which immediately prior to the Effective Date represented outstanding shares of
Old Common Stock (the "Old Certificates," whether one or more) shall be entitled
to receive upon surrender of such Old Certificates to the Corporation for
cancellation, a certificate or certificates (the "New Certificates," whether one
or more) representing the number of whole shares of the New Common Stock
determined by multiplying the number of shares of Old Common Stock represented
by such Old Certificate(s) immediately prior to the Effective Date by 0.2841 and
rounding such number up to the next whole integer. From and after the Effective
Date, Old Certificates shall represent only the right to receive New
Certificates pursuant to the provisions hereof.

          (b) No certificates or scrip representing fractional share interests
in New Common Stock will be issued. If more than one Old Certificate shall be
surrendered at one time for the account of the same stockholder, the number of
full shares of New Common Stock for which New Certificates shall be issued shall
be computed on the basis of the aggregate number of shares represented by the
Old Certificates so surrendered. In the event that the Corporation

                                       -4-



determines that a holder of Old Certificates has not tendered all his
certificates for exchange, the Corporation shall carry forward any fractional
share until all certificates of that holder have been presented for exchange
such that rounding up for fractional shares to any one person shall not exceed
one share in the aggregate.

          (c) If any New Certificate is to be issued in a name other than that
in which the Old Certificates surrendered for exchange are issued, the Old
Certificates so surrendered shall be properly endorsed and otherwise in proper
form for transfer, and the Person or Persons requesting such exchange shall
affix any requisite stock transfer tax stamps to the Old Certificates
surrendered, or provide funds for their purchase, or establish to the
satisfaction of the Corporation that such taxes are not payable.

          (d) From and after the Effective Date, the amount of capital
represented by each share of New Common Stock shall be the same as the amount of
capital represented by each share of Old Common Stock.

                                    ARTICLE V

                            SERIES A PREFERRED STOCK

          Section 1. Designation and Amount. The shares of such series shall be
designated as "Series A Convertible Preferred Stock" and the number of shares
constituting such series shall be 4,500,000.

          Section 2. Issuance of Additional Shares. The number of authorized
shares of the Series A Preferred Stock may be reduced or eliminated by the Board
or a duly-authorized committee thereof in compliance with the DGCL stating that
such reduction has been authorized, but the number of authorized shares of
Series A Preferred Stock shall not be increased.

          Section 3. Certain Definitions. For purposes of this Article V, the
following definitions shall apply:

     "Business Day" shall mean any day excluding Saturday, Sunday and any day
which shall be in the State of New York a legal holiday or a day on which
banking institutions in the State of New York are authorized by law to close.

     "Issuance Date" shall mean the date of original issuance of the Series A
Preferred Stock.

     "Junior Stock" shall mean the Common Stock and any shares of Preferred
Stock of any series or class of the Corporation, whether presently outstanding
or hereafter issued, which are by their terms expressly made junior to the
shares of Series A Preferred Stock at the time outstanding as to the
distribution of assets on any voluntary or involuntary liquidation, dissolution
or winding up of the Corporation and are not subject to mandatory redemption or
repurchase prior to the date on which no shares of Series A Preferred Stock are
outstanding.

     "Majority of the Series A Preferred Stock" shall mean more than fifty
percent (50%) of the outstanding shares of Series A Preferred Stock.

                                      -5-



     "Preferred Stock" shall mean the Undesignated Preferred Stock.

     "Redemption Date" shall have the meaning assigned to such term in Section
6(b) of this Article V.

     "Redemption Price" shall have the meaning assigned to such term in Section
6(c) of this Article V.

     "Redemption Notice" shall have the meaning assigned to such term in Section
6(d) of this Article V.

     "Series A Conversion Ratio" shall have the meaning assigned to such term in
Section 8(b) of this Article V.

     "Shared Allocation" shall have the meaning assigned to such term in Section
5(c) of this Article V.

     "Subsidiary" shall mean any corporation, limited liability company or other
entity, a majority of the voting stock or interest of which is, at the time as
of which any determination is being made, owned by the Corporation either
directly or through one or more Subsidiaries.

     "Voting Stock" shall mean any shares having general voting power in
electing the Board (irrespective of whether or not at the time stock of any
other class or classes has or might have voting power by reason of the
occurrence of any contingency). The Common Stock, the Series A Preferred Stock
and the Priority Preferred Stock are Voting Stock.

          Section 4. Dividends.

          (a) Dividends and Distributions. Subject to the prior and superior
rights of the holders of any shares of any series or class of capital stock
ranking prior and superior to the shares of Series A Preferred Stock with
respect to dividends, the holders of shares of Series A Preferred Stock shall be
entitled to receive, as, when and if declared by the Board of Directors of the
Corporation, out of assets legally available for that purpose, dividends or
distributions in cash, stock or otherwise.

          (b) If and when the Corporation shall declare any dividend or
distribution on any Junior Stock, the Corporation shall, concurrently with the
declaration of such dividend or distribution on the Junior Stock, declare a like
dividend or distribution, as the case may be, on the Series A Preferred Stock in
an amount per share equal to (x) the amount of the dividend or distribution per
share of Common Stock multiplied by (y) the number of shares of Common Stock
into which one (1) share of Series A Preferred Stock is then convertible.

          (c) Any dividend or distribution payable to the holders of the Series
A Preferred Stock pursuant to this Section 4 shall be paid to such holders at
the same time as the dividend or distribution on the Junior Stock by which it is
measured is paid.

          (d) All dividends or distributions declared upon the Series A
Preferred Stock shall be declared pro rata per share.

                                       -6-



          Section 5. Liquidation Rights of Series A Preferred Stock.

          (a) Preference of Series A Preferred Stock. In the event of a
liquidation, dissolution or winding up of the Corporation, whether voluntary or
involuntary (for the purposes of this Article V, a "Liquidation Event"), after
payment or provision for payment of debts and other liabilities of the
Corporation and subject to the prior and superior rights of the holders of any
shares of any series or class of capital stock ranking prior and superior to the
shares of Series A Preferred Stock with respect to liquidation, the holder of
the Series A Preferred Stock then outstanding shall first be entitled to be paid
out of the assets of the Corporation available for distribution to its
stockholders, whether such assets are capital, surplus, or earnings, before any
payment or declaration and setting apart for payment of any amount shall be made
in respect of Junior Stock, an amount equal to $1.25 per share of Series A
Preferred Stock (subject to appropriate adjustment to reflect any stock split
combination, reclassification or reorganization of the Series A Preferred Stock)
plus an amount equal to all declared and unpaid dividends thereon. After the
payment or distribution to the holders of the Series A Preferred Stock of the
full preferential amounts set forth in the immediately preceding sentence, the
remaining assets available for distribution shall be distributed as a Shared
Allocation. If upon any Liquidation Event, whether voluntary or involuntary, the
assets to be distributed to the holders of the Series A Preferred Stock shall be
insufficient to permit the payment to such stockholders of the full preferential
amounts aforesaid, then all of the assets of the Corporation to be distributed
shall be so distributed ratably to the holders of the Series A Preferred Stock
on the basis of the number of shares of Series A Preferred Stock held. All
shares of Series A Preferred Stock shall rank as to payment, upon the occurrence
of a Liquidation Event, senior to the Common Stock as provided herein and,
unless the terms of such series shall provide otherwise, senior to all other
series of the Corporation's preferred stock.

          (b) Consent to Certain Transactions. Each holder of shares of Voting
Stock shall, by virtue of its acceptance of a stock certificate evidencing such
Voting Stock, be treated as having consented, for all purposes, to distributions
made by the Corporation in connection with the repurchase of shares of Common
Stock from directors or employees of or consultants or advisers to the
Corporation or any Subsidiary upon the termination of employment by or service
to the Corporation or any Subsidiary or otherwise.

          (c) "Shared Allocation" means that the holders of Series D Preferred
Stock, Priority Preferred Stock, the holders of Series A Preferred Stock and the
holders of any other shares of any series or class of capital stock with
participation rights (the "Other Participating Securities") and Common Stock
shall share the remaining assets of the Corporation available for distribution
to its stockholders in the same proportion as the number of shares of
outstanding Common Stock issuable upon the conversion of outstanding Series A
Preferred Stock, Series D Preferred Stock, Priority Preferred Stock and Other
Participating Securities then held by each such stockholder bears to the total
number of shares of outstanding Common Stock plus the Common Stock issuable upon
conversion of outstanding Series A Preferred Stock, Series D Preferred Stock,
Priority Preferred Stock and Other Participating Securities.

          Section 6. Redemption.

                                       -7-



          (a) Restriction on Redemption and Purchase. Except as expressly
provided in this Section 6, the Corporation shall not have the right to
purchase, call, redeem or otherwise acquire for value any or all of the Series A
Preferred Stock.

          (b) Optional Redemption. At any time after the Issuance Date, the
Corporation may, at its option, redeem the Series A Preferred Stock in whole, or
in part, on a pro rata basis, at the Redemption Price hereinafter specified;
provided, however, that the Corporation shall not redeem Series A Preferred
Stock or give notice of any redemption unless the Corporation has sufficient and
lawful funds to redeem all of the then outstanding Series A Preferred Stock. The
date on which the Series A Preferred Stock is to be redeemed pursuant to this
Section 6(b) is herein called the "Redemption Date."

          (c) Redemption Price. The Redemption Price of the Series A Preferred
Stock (for the purposes of this Article V, the "Redemption Price") shall be an
amount per share equal to $1.25 (subject to appropriate adjustment to reflect
any stock split, combination, reclassification or reorganization of the Series A
Preferred Stock) plus all declared and unpaid dividends thereon, to and
including the Redemption Date.

          (d) Redemption Notice. The Corporation shall, not less than thirty
(30) days nor more than sixty (60) days prior to the Redemption Date, give
written notice ("Redemption Notice") to each holder of record of Series A
Preferred Stock to be redeemed. The Redemption Notice shall state:

               (1) that all of the outstanding shares of Series A Preferred
          Stock are to be redeemed and the total number of shares being
          redeemed;

               (2) the number of shares of Series A Preferred Stock held by the
          holder which the Corporation intends to redeem;

               (3) the Redemption Date and Redemption Price;

               (4) that the holder's right to convert the Series A Preferred
          Stock into shares of Common Stock as provided in Section 8 hereof will
          terminate on the Redemption Date; and

               (5) the time, place and manner in which the holder is to
          surrender to the Corporation the certificate or certificates
          representing the shares of Series A Preferred Stock to be redeemed.

          (e) Payment of Redemption Price and Surrender of Stock. On the
Redemption Date, the Redemption Price of the Series A Preferred Stock scheduled
to be redeemed or called for redemption shall be payable to the holders of the
Series A Preferred Stock. On or before the Redemption Date, each holder of
Series A Preferred Stock to be redeemed, unless the holder has exercised his
right to convert the shares as provided in Section 8 hereof, shall surrender the
certificate or certificates representing such shares to the Corporation, in the
manner and at the place designated in the Redemption Notice, and thereupon the
Redemption Price for such shares

                                       -8-



shall be payable to the order of the Person whose name appears on such
certificate or certificates as the owner thereof, and each surrendered
certificate shall be canceled and retired.

          (f) Termination of Rights. If the Redemption Notice is duly given,
and, if at least ten (10) days prior to the Redemption Date, the Redemption
Price is either paid or made available for payment through the arrangement
specified in subsection (g) below, then notwithstanding that the certificates
evidencing any of the shares of Series A Preferred Stock so called or scheduled
for redemption have not been surrendered, all rights with respect to such shares
shall forthwith after the Redemption Date cease and terminate, except only (i)
the right of the holders to receive the Redemption Price without interest upon
surrender of their certificates therefor or (ii) the right to receive shares of
Common Stock upon exercise of the conversion rights provided in Section 8 hereof
on or before the Redemption Date.

          (g) Deposit of Funds. At least ten (10) days prior to the Redemption
Date, the Corporation shall deposit with any bank or trust company in New York,
New York, a sum equal to the aggregate Redemption Price of all shares of the
Series A Preferred Stock scheduled to be redeemed or called for redemption and
not yet redeemed, with irrevocable instructions and authority to the bank or
trust company to pay the Redemption Price to the respective holders upon the
surrender of their share certificates. The deposit shall constitute full payment
for the shares of Series A Preferred Stock to the holders thereof, and from and
after the date of such deposit (even if prior to the Redemption Date), the
shares of Series A Preferred Stock shall be deemed to be redeemed and no longer
outstanding, and the holders thereof shall cease to be stockholders with respect
to such shares of Series A Preferred Stock and shall have no rights with respect
thereto, except the right to receive from the bank or trust company payment of
the Redemption Price of the shares of Series A Preferred Stock, without
interest, upon surrender of their certificates therefor and the right to convert
such shares of Series A Preferred Stock into shares of Common Stock as provided
in Section 8 hereof. Any monies so deposited and unclaimed at the end of one
year from the Redemption Date shall be released or repaid to the Corporation,
after which time the holders of shares of Series A Preferred Stock called for
redemption shall be entitled to receive payment of the Redemption Price only
from the Corporation.

          Section 7. Voting Rights.

          (a) Series A Preferred Stock. Each holder of shares of Series A
Preferred Stock shall be entitled to vote on all matters and, except as
otherwise expressly provided herein, shall be entitled to the number of votes
equal to the largest number of full shares of Common Stock into which the shares
of Series A Preferred Stock of such holder could be converted, pursuant to the
provisions of Section 8 hereof, at the record date for the determination of the
stockholders entitled to vote on such matters or, if no such record date is
established, at the date such vote is taken.

          (b) Amendment of Certificate of Incorporation. Any amendment to the
Certificate of Incorporation of the Corporation that adversely affects the
conversion terms of the Series A Preferred Stock shall require the approval of
the holders of a Majority of the Series A Preferred Stock.

                                       -9-



          Section 8. Conversion. The holders of Series A Preferred Stock shall
have the following conversion rights:

          (a) Right to Convert. Each share of Series A Preferred Stock shall be
convertible, at any time at the option of the holder thereof, into validly
issued, fully paid and nonassessable shares of Common Stock.

          (b) Series A Conversion Ratio. Each share of Series A Preferred Stock
shall be convertible into shares of Common Stock at a ratio (as used in this
Article V, the "Series A Conversion Ratio") equal to one share of Common Stock
for each share of Series A Preferred Stock, subject to adjustment as hereinafter
provided.

          (c) Dividends Upon Conversion. Upon conversion all accrued dividends
(whether or not declared), if any, on the Series A Preferred Stock shall be
canceled.

          (d) Automatic Conversion.

               (1) The Series A Preferred Stock will be automatically converted
          into shares of Common Stock (i) upon the closing of the first
          underwritten public offering of the Common Stock pursuant to an
          effective registration statement under the Securities Act of 1933, as
          amended, or (ii) upon receipt by the Corporation of a written notice
          from the holders of a Majority of the Series A Preferred Stock
          electing to convert their shares of Series A Preferred Stock.

               (2) Upon the occurrence of any of the events specified in
          paragraph (d)(1) above, the outstanding shares of Series A Preferred
          Stock shall be converted automatically without any further action by
          the holders of such shares and whether or not the certificates
          representing such shares are surrendered to the Corporation or its
          transfer agent; provided, however, that the Corporation shall not be
          obligated to issue certificates evidencing the shares of Common Stock
          issuable upon such conversion unless the certificates evidencing such
          shares of Series A Preferred Stock are either delivered to the
          Corporation or its transfer agent as provided below, or the holder
          thereof notifies the Corporation or its transfer agent that such
          certificates have been lost, stolen, mutilated or destroyed and
          executes an agreement satisfactory to the Corporation to indemnify the
          Corporation from any loss incurred by it in connection with such
          certificates. Upon the occurrence of such automatic conversion of the
          Series A Preferred Stock, the holders of Series A Preferred Stock
          shall surrender the certificates representing such shares at the
          office of the Corporation or any transfer agent for the Series A
          Preferred Stock. Thereupon, there shall be issued and delivered to
          such holder promptly at such office and in its name as shown on such

                                      -10-



          surrendered certificate or certificates, a certificate or certificates
          for the number of shares of Common Stock into which the shares of
          Series A Preferred Stock surrendered were convertible on the date on
          which such automatic conversion occurred.

          (e) Mechanics of Conversion. Each holder of Series A Preferred Stock
desiring to convert its shares of Series A Preferred Stock into shares of Common
Stock shall surrender the certificate or certificates therefor, duly endorsed,
at the office of the Corporation or of any transfer agent for the Series A
Preferred Stock or Common Stock and shall give written notice to the Corporation
at such office that such holder elects to convert the same and shall state
therein the number of shares of Series A Preferred Stock being converted.
Thereupon the Corporation shall promptly issue and deliver to such holder a
certificate or certificates for the number of shares of Common Stock to which
such holder is entitled. Such conversion shall be deemed to have been made
immediately prior to the close of business on the date of such surrender of the
certificate or certificates representing the shares of Series A Preferred Stock
to be converted, and the Person entitled to receive the shares of Common Stock
issuable upon such conversion shall be treated for all purposes as the record
holder of such shares of Common Stock on such date. In the event that a notice
to convert is given following a Redemption Notice and such redemption is not
consummated, the conversion shall, at the option of the holder of the Series A
Preferred Stock who tendered for conversion, be voidable and such holder shall
have the right to maintain ownership of the shares of Series A Preferred Stock
tendered for conversion.

          (f) Adjustment for Stock Splits and Combinations. If the Corporation
at any time or from time to time after the Issuance Date effects a subdivision
of the outstanding Common Stock, the Series A Conversion Ratio then in effect
immediately before that subdivision shall be proportionately increased, and
conversely, if the Corporation at any time or from time to time after the
Issuance Date combines the outstanding shares of Common Stock into a smaller
number of shares (including, without limitation, as contemplated by the reverse
stock split referred to in Section 4 of Article IV), then the Series A
Conversion Ratio then in effect immediately before the combination shall be
proportionately decreased. Any adjustment under this subsection (f) shall become
effective at the close of business on the date the subdivision or combination
becomes effective.

          (g) Adjustment for Certain Dividends and Distributions. If the
Corporation at any time or from time to time after the Issuance Date makes, or
fixes a record date for the determination of holders of Common Stock entitled to
receive, a dividend or other distribution payable in additional shares of Common
Stock, then and in each such event the Series A Conversion Ratio then in effect
shall be increased as of the time of such issuance or, in the event such record
date is fixed, as of the close of business on such record date, by multiplying
the Series A Conversion Ratio then in effect by a fraction (1) the numerator of
which shall be the total number of shares of Common Stock issued and outstanding
immediately prior to the time of such issuance or the close of business on such
record date plus the number of shares of Common Stock issuable in payment of
such dividend or distribution, and (2) the denominator of which shall be the
total number of shares of Common Stock issued and outstanding immediately prior
to the time of such issuance or the close of business on such record date;
provided, however, that, if such record date is fixed and such dividend is not
fully paid or if such distribution is not fully made on the date fixed therefor,
the Series A Conversion Ratio shall be recomputed accordingly

                                      -11-



as of the close of business on such record date and thereafter the Series A
Conversion Ratio shall be adjusted pursuant to this subsection (g) as of the
time of actual payment of such dividends or distributions.

          (h) Adjustments for Other Dividends and Distributions. In the event
the Corporation at any time or from time to time after the Issuance Date makes,
or fixes a record date for the determination of holders of Common Stock entitled
to receive, a dividend or other distribution payable in securities of the
Corporation other than shares of Common Stock, then and in each such event
provision shall be made so that the holders of Series A Preferred Stock shall
receive upon conversion thereof, in addition to the number of shares of Common
Stock receivable thereupon, the amount of securities of the Corporation which
they would have received had their shares of Series A Preferred Stock been
converted into Common Stock on the date of such event and had they thereafter,
during the period from the date of such event to and including the conversion
date, retained such securities receivable by them as aforesaid during such
period subject to all other adjustments called for during such period under this
Section 8.

          (i) Adjustment for Reclassification, Exchange and Substitution. In the
event that at any time or from time to time after the Issuance Date, the Common
Stock issuable upon the conversion of the Series A Preferred Stock is changed
into the same or a different number of shares of any class or classes of stock,
whether by recapitalization, reclassification or otherwise (other than a
subdivision or combination of shares or stock dividend or a reorganization,
merger, consolidation or sale of assets, provided for elsewhere in this Section
8), then and in any such event each holder of Series A Preferred Stock shall
have the right thereafter to convert such Series A Preferred Stock into the kind
and amount of stock and other securities and property receivable upon such
recapitalization, reclassification or other change, by holders of the maximum
number of shares of Common Stock into which such shares of Series A Preferred
Stock could have been converted immediately prior to such recapitalization,
reclassification or change, all subject to further adjustment as provided
herein.

          (j) Reorganizations, Mergers, Consolidations or Sales of Assets. If at
any time or from time to time after the Issuance Date there is a capital
reorganization of the Common Stock (other than a recapitalization, subdivision,
combination, reclassification or exchange of shares provided for elsewhere in
this Section 8) or a merger or consolidation of the Corporation with or into
another corporation, or the sale of all or substantially all of the
Corporation's properties and assets to any other Person, then, as part of such
reorganization, merger, consolidation or sale, provision shall be made so that
the holders of the Series A Preferred Stock shall thereafter be entitled to
receive upon conversion of the Series A Preferred Stock the number of shares of
stock or other securities or property to which a holder of the number of shares
of Common Stock deliverable upon conversion would have been entitled on such
capital reorganization, merger, consolidation or sale. In any such case,
appropriate adjustment shall be made in the application of the provisions of
this Section 8 with respect to the rights of the holders of the Series A
Preferred Stock after the reorganization, merger, consolidation or sale to the
end that the provisions of this Section 8 (including adjustment of the Series A
Conversion Ratio then in effect and the number of shares purchasable upon
conversion of the Series A Preferred Stock) shall be applicable after that event
and be as nearly equivalent as may be practicable.

                                      -12-



          (k) Certificate of Adjustment. In each case of an adjustment or
readjustment of the Series A Conversion Ratio, the Corporation, at its expense,
shall cause its Chief Financial Officer or Chief Accounting Officer to compute
such adjustment or readjustment in accordance with the provisions hereof and
prepare a certificate showing such adjustment or readjustment, and shall mail
such certificate, by certified mail, return receipt requested, postage prepaid,
to each registered holder of the Series A Preferred Stock at the holder's
address as shown in the Corporation's books. The certificate shall set forth
such adjustment or readjustment, showing in detail the facts upon which such
adjustment or readjustment is based, including a statement of (1) the Series A
Conversion Ratio at the time in effect and (2) the type and amount, if any, of
other property which at the time would be received upon conversion of the Series
A Preferred Stock.

          (l) Notices of Record Date. In the event of (i) any taking by the
Corporation of a record of the holders of any class of securities for the
purpose of determining the holders thereof who are entitled to receive any
dividend or other distribution, or (ii) any capital reorganization of the
Corporation, any reclassification or recapitalization of the capital stock of
the Corporation, any merger or consolidation of the Corporation with or into any
other corporation or other entity, or any transfer of all or substantially all
of the assets of the Corporation to any other Person or any voluntary or
involuntary dissolution, liquidation or winding up of the Corporation, the
Corporation shall mail to each holder of Series A Preferred Stock at least
thirty (30) days prior to the record date specified therein, a notice specifying
(1) the date on which any such record is to be taken for the purpose of such
dividend or distribution and a description of such dividend or distribution, (2)
the date on which any such reorganization, reclassification, transfer,
consolidation, merger, dissolution, liquidation or winding up is expected to
become effective, and (3) the date, if any, that is to be fixed as to when the
holders of record of Common Stock (or other securities) shall be entitled to
exchange their shares of Common Stock (or other securities) for securities or
other property deliverable upon such reorganization, reclassification, transfer,
consolidation, merger, dissolution, liquidation or winding up.

          (m) Fractional Shares. No fractional shares of Common Stock shall be
issued upon conversion of the Series A Preferred Stock. In lieu of any
fractional share to which the holder would otherwise be entitled, the
Corporation shall pay cash equal to the product of such fraction multiplied by
the fair market value of one share of Common Stock on the date of conversion, as
determined in good faith by the Board.

          (n) Reservation of Common Stock Issuable Upon Conversion. The
Corporation shall at all times reserve and keep available out of its authorized
but unissued shares of Common Stock, solely for the purpose of effecting the
conversion of the shares of the Series A Preferred Stock, such number of its
shares of Common Stock as shall from time to time be sufficient to effect the
conversion of all outstanding shares of the Series A Preferred Stock.

          (o) Notices. Any notice required or permitted by this Section 8 or any
other provision hereof to be given shall be deemed sufficient if in writing and
sent by (i) telecopy or facsimile at the address or number designated below (if
delivered on a business day during normal business hours where such notice is to
be received) or (ii) upon the earlier of actual receipt or three (3) days alter
the same has been deposited in the United States mail, by certified or
registered mail, return receipt requested, postage prepaid, and addressed (x) to
each holder of

                                      -13-



record of Series A Preferred Stock at the address of such holder appearing on
the books of the Corporation, or (y) to the Corporation at 3960 Broadway, 4th
Floor, New York, NY 10032 or (z) to the Corporation or any such holder, at any
other address for the giving of notice specified in a written notice given to
the other.

          (p) Payment of Taxes. The Corporation will pay all taxes (other than
taxes based upon income) and other governmental charges that may be imposed with
respect to the issue or delivery of shares of Common Stock upon conversion of
shares of Series A Preferred Stock, including, without limitation, any tax or
other charge imposed in connection with any transfer involved in the issue and
delivery of shares of Common Stock in a name other than that in which the shares
of Series A Preferred Stock so converted were registered.

          Section 9. Amendment. None of the powers, preferences and relative,
participating, optional and other special rights of the Series A Preferred Stock
as provided herein or in the Certificate of Incorporation shall be amended in
any manner which would alter or change the powers, preferences, rights of
privileges of the holders of the Series A Preferred Stock so as to affect them
adversely without the affirmative vote of the holders of a majority of the
outstanding shares of the Series A Preferred Stock, voting as a separate class.

          Section 10. Outstanding Shares. For purposes of this Article V, all
shares of Series A Preferred Stock shall be deemed outstanding except (i) from
the date, or the deemed date, of surrender of certificates evidencing shares of
Series A Preferred Stock, all shares of Series A Preferred Stock converted into
Common Stock, (ii) from the date of registration of transfer, all shares of
Series A Preferred Stock held of record by the Corporation or any subsidiary of
the Corporation and (iii) any and all shares of Series A Preferred Stock held in
escrow prior to delivery of such stock by the Corporation to the initial
beneficial owners thereof.

          Section 11. Preemptive Rights. The Series A Preferred Stock is not
entitled to any preemptive or subscription rights in respect of any securities
of the Corporation,

          Section 12. Severability of Provisions. Whenever possible, each
provision of this Article V shall be interpreted in a manner as to be effective
and valid under applicable law, but if any provision hereof is held to be
prohibited by or invalid under applicable law, such provision shall be
ineffective only to the extent of such prohibition or invalidity, without
invalidating or otherwise adversely affecting the remaining provisions hereof.
If a court of competent jurisdiction should determine that a provision hereof
would be valid or enforceable if a period of time were extended or shortened or
a particular percentage were increased or decreased, then such court may make
such change as shall be necessary to render the provision in question effective
and valid under applicable law.

                                   ARTICLE VI

                            SERIES B PREFERRED STOCK

          Section 1. Number and Designation. Defined terms used in this Article
VI and not defined herein shall have the meaning ascribed to such terms in
Article IV of this Certificate of Incorporation. In addition, certain terms used
in this Article VI are defined in section 7 hereof.

                                      -14-



     The shares of such series shall be designated as "Series B Convertible
Preferred Stock" and the number of shares constituting such series shall be
2,333,333.

          Section 2. Dividends.

          (a) The holders of the Series B Preferred Stock shall be entitled to
receive, when, as and if declared by the Board, out of funds legally available
for that purpose, dividends on each share of Series B Preferred Stock which
shall accrue on a daily basis at the Applicable Dividend Rate (compounded
annually on each anniversary of the Original Issuance Date), on the Liquidation
Amount, payable in cash. Dividends shall be cumulative and shall accrue at the
Applicable Dividend Rate on the Liquidation Amount regardless of whether the
Board has declared a dividend payment or whether there are any profits, surplus
or other funds of the Corporation legally available for dividends. Dividends
shall accrue pursuant to this Section 2 from and including the Original Issuance
Date to and including the date each share of Series B Preferred Stock is
redeemed in full. All payments or accruals due under this Section 2 to any
holder of Series B Preferred Stock shall be made or accrued to the nearest cent.

          (b) The dividends payable with respect to the Series B Preferred Stock
shall be paid to the holders of Series B Preferred Stock as they appear on the
stock records of the Corporation on such date as shall be fixed by the Board.

          (c) Except as otherwise provided herein, if at any time the
Corporation pays less than the total amount of dividends then accrued with
respect to the Series B Preferred Stock, such payment shall be distributed
ratably among the holders of Series B Preferred Stock based upon the number of
shares of the Series B Preferred Stock held by each such holder.

          (d) In the event the Corporation shall fail to pay in full all accrued
dividends on all shares of Series B Preferred Stock, then the Corporation shall
not thereafter declare or pay or set apart for payment any dividend or other
distribution upon shares of Common Stock, or any other stock of the Corporation
ranking on a parity with or junior to the Series B Preferred Stock as to
dividends. The Series B Preferred Stock shall rank on a parity with the shares
of other Priority Preferred Stock, and shall rank prior and superior to the
shares of Series A Preferred Stock and Common Stock, with respect to dividends.

          (e) The holders of the Series B Preferred Stock and the holders of
other Priority Preferred Stock shall participate (on an as-converted basis) in
any and all dividend payments on the Common Stock when, as and if dividends are
paid with respect to the Common Stock.

          Section 3. Liquidation.

          (a) Upon any Liquidation of the Corporation, the holders of shares of
Series B Preferred Stock then outstanding shall be entitled to be paid out of
the assets of the Corporation available for distribution to its stockholders,
after the payment or provision for payment of debts and other liabilities of the
Corporation and after and subject to the payment in full of all amounts required
to be distributed to the holders of any other series or class of stock of the
Corporation ranking on Liquidation prior and in preference to the Series B
Preferred Stock upon such Liquidation but on a parity with the other Priority
Preferred Stock and each other series or class of stock of the Corporation
ranking on Liquidation on a parity with the Series B Preferred Stock,

                                      -15-



but before any distribution or payment is made upon any common, preferred or any
other capital stock of the Corporation ranking on Liquidation junior to the
Series B Preferred Stock, an amount equal to the Liquidation Amount for each
such share of Series B Preferred Stock on the date of such Liquidation (such
amount payable with respect to one share of Series B Preferred Stock sometimes
being referred to in this Article VI as the "Liquidation Preference Payment" and
with respect to all shares of Series B Preferred Stock being sometimes referred
to in this Article VI as the "Liquidation Preference Payments").

          (b) If upon a Liquidation of the Corporation, the assets to be
distributed among the holders of Series B Preferred Stock shall be insufficient
to permit payment in full of the Liquidation Preference Payments to the holders
of Series B Preferred Stock, then the holders of the Series B Preferred Stock,
proportionately with the holders of other Priority Preferred Stock, shall share
in the entire assets of the Corporation to be so distributed in proportion to
the full Liquidation Preference Payment each such holder of Series B Preferred
Stock and other Priority Preferred Stock would otherwise be entitled to receive.
After the Liquidation Preference Payments shall have been made in full, the
remaining net assets of the Corporation available for distribution shall be
distributed (i) pursuant to the first sentence of Section 5(a) of Article V of
this Certificate of Incorporation (as used in this Article VI, the "Series A
Liquidation Preference Payment") and (ii) after the payment or distribution in
full of the Series A Liquidation Preference Payment, the remaining net assets of
the Corporation shall be distributed as a Shared Allocation.

          (c) Written notice of such Liquidation, stating a payment date, the
amount of the Liquidation Preference Payments, and the place where said
Liquidation Preference Payments shall be payable, shall be delivered in person,
mailed by certified or registered mail, return receipt requested, or sent by
telecopier or telex, not less than 20 days prior to the payment date stated
therein, to the holders of record of Series B Preferred Stock. Such notice shall
be addressed to each such holder at its address as shown by the records of the
Corporation.

          Section 4. Redemption.

          (a) Upon the election of the holders of at least two-thirds of the
shares of Series B Preferred Stock and other Priority Preferred Stock and Series
D Preferred Stock, in the aggregate, then outstanding, voting together as a
class (calculated on an as-converted basis), the holders of such shares shall
have the right to require the Corporation to redeem all or a portion of such
shares on a date (as used in this Article VI, the "Redemption Date") on or at
any time after February 8, 2005 for the Series B Preferred Stock, at any time
after May 16, 2005 for the Series C Preferred Stock and on or at any time after
February 8, 2005 for the Series D Preferred Stock, upon not less than 15 days
prior written notice. At least 10 days prior to the Redemption Date, the
Corporation shall notify each respective holder of Series B Preferred Stock and
other Priority Preferred Stock and Series D Preferred Stock of such holder's
right of optional redemption under this Section 4. Each holder of Series B
Preferred Stock or other Priority Preferred Stock or Series D Preferred Stock
may elect its preference to have its shares, or any portion thereof, redeemed
under this Section 4(a) by notifying the Corporation of such election; provided,
however, that the Corporation shall only be required to redeem such shares if
the holders of a least two-thirds of the shares of Series B Preferred Stock and
other Priority Preferred Stock and Series D Preferred Stock, in the aggregate
(calculated on an as-converted basis), elect to have at least two-thirds of the
shares of Series B Preferred Stock and other Priority Preferred Stock and

                                      -16-



Series D Preferred Stock redeemed. If the assets of the Corporation available
for redemption of the Series B Preferred Stock and other Priority Preferred
Stock and Series D Preferred Stock shall be insufficient to permit the payment
of the full price required to be paid under this Section 4, then the holders of
Series B Preferred Stock and other Priority Preferred Stock and Series D
Preferred Stock shall share ratably in any such redemption according to the
respective amounts which would be payable in respect of the number of shares
that such holders own if all amounts payable on or with respect to such shares
were paid in full.

          (b) On and after any Redemption Date, all rights in respect of the
shares of Series B Preferred Stock to be redeemed on such Redemption Date,
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 Corporation;
provided, however, that if default shall be made by the Corporation in the
payment of the Redemption Price, such rights shall remain in full force and
effect and be exercisable, and such shares shall be deemed to remain
outstanding, until such default is cured.

          (c) Anything contained in this Section 4 to the contrary
notwithstanding, the holders of shares of Series B Preferred Stock and other
Priority Preferred Stock and Series D Preferred Stock requested by such holders
as herein provided to be redeemed pursuant to this Section 4 shall have no
right, after such request, to convert all or any part of such shares to be
redeemed as herein provided into shares of Common Stock pursuant to Section 6
hereof; provided, however, that if default shall be made by the Corporation in
the payment of the Redemption Price as herein provided, such right shall be
exercisable until such default is cured. If and to the extent, any shares of
Series B Preferred Stock and other Priority Preferred Stock and Series D
Preferred Stock so entitled to redemption are converted into shares of Common
Stock by the holders thereof prior to the close of business on the Redemption
Date, the total number of shares of Series B Preferred Stock and other Priority
Preferred Stock and Series D Preferred Stock otherwise to be redeemed on such
date shall be reduced by the number of shares of Series B Preferred Stock and
other Priority Preferred Stock and Series D Preferred Stock so converted.

          (d) To the extent that on any Redemption Date the Corporation is not
legally permitted (by Delaware law, this Certificate of Incorporation, its
By-laws, contractual provisions or otherwise) to pay the Redemption Price of any
shares of Series B Preferred Stock required to be redeemed by the Corporation on
such Redemption Date, the Corporation shall promptly take all action (including,
without limitation, a revaluation of assets or a prepayment of indebtedness
restricting such redemption) as may be permitted by applicable law to permit
such redemption in full. If the Corporation remains unable after the taking of
such action to repurchase any or all of such shares, the Corporation shall
immediately repurchase such shares upon the termination of such legal
prohibition.

          (e) The price (as used in this Article VI, the "Redemption Price") at
which each share of Series B Preferred Stock is to be redeemed by the
Corporation pursuant to this Section 4 shall be equal to the greater of (i) the
Liquidation Amount of such share on the date of such redemption and (ii) the
Fair Market Value of such share on the date of redemption. The conversion of any
shares of the Series B Preferred Stock into Common Stock shall have no effect on
the Redemption Price payable in connection with the redemption of the shares of
Series B Preferred Stock not so converted.

                                      -17-



          (f) Any communication or notice relating to redemption given pursuant
to this Section 4 shall be sent by first-class certified mail, return receipt
requested, postage prepaid, to the holders of record of shares of Series B
Preferred Stock, at their respective addresses as the same shall appear on the
books of the Corporation, or to the Corporation at the address of its principal,
or registered office, as the case may be. At any time on or after the Redemption
Date, the holders of record of shares of Series B Preferred Stock being redeemed
in accordance with this Section 4 shall be entitled to receive the Redemption
Price as determined upon actual delivery to the Corporation or its agents of the
certificates representing the shares to be redeemed.

          Section 5. Voting Rights.

          (a) In addition to the rights provided by law or in the Corporation's
By-laws, each share of Series B Preferred Stock shall entitle the holder thereof
to such number of votes as shall equal the number of shares of Common Stock into
which such share of Series B Preferred Stock is then convertible pursuant to
Section 6 at the record date for the determination of stockholders entitled to
vote or, if no record date is established, at the date such vote is taken. In
addition to class or series voting rights provided by law or in this Certificate
of Incorporation, the holders of Series B Preferred Stock shall be entitled to
vote on all matters as to which holders of Common Stock shall be entitled to
vote in the same manner and with the same effect as such holders of Common
Stock, voting together with the holders of Common Stock, the holders of the
Series A Preferred Stock (calculated on an as-converted basis ) and the holders
of other Priority Preferred Stock (calculated on an as-converted basis) as one
class.

          (b) In addition to the other rights specified in this Section 5, the
holders of a majority of the shares of Series B Preferred Stock outstanding,
voting separately as one class, shall at all times have the special and
exclusive right to elect one director to the Board, in accordance with the
provisions set forth in the Stockholders' Agreement. In any election of
directors by the holders of Series B Preferred Stock pursuant to this Section
5(b), each holder of Series B Preferred Stock shall be entitled to one vote for
each share of Series B Preferred Stock held. The Corporation shall take all
actions necessary to effectuate the terms and provisions of this Section 5(b).
The special and exclusive voting rights of the holders of Series B Preferred
Stock contained in this Section 5(b) may be exercised either at a special
meeting of the holders of Series B Preferred Stock called as provided below, or
at any annual or special meeting of the stockholders of the Corporation, or by
written consent of such holders in lieu of a meeting. The director to be elected
pursuant to this Section 5(b) shall serve for terms extending from the date of
his or her election and qualification until his or her successors shall have
been elected and qualified. If at any time the directorship to be filled by the
holders of Series B Preferred Stock pursuant to this Section 5(b) has been
vacant for a period of 10 days, the Secretary of the Corporation shall, upon the
written request of any holder of Series B Preferred Stock, call a special
meeting of the holders of Series B Preferred Stock for the purpose of electing a
director to fill such vacancy. Such meeting shall be held at the earliest
practicable date, and at such place, as is specified in or determined in
accordance with the By-laws of the Corporation. If such meeting shall not be
called by the Secretary of the Corporation within 10 days after personal service
of such written request on the Secretary of the Corporation, then any holder of
Series B Preferred Stock may designate in writing any holder of Series B
Preferred Stock to call such meeting at the expense of the Corporation, and such
meeting may be called by such person

                                      -18-



so designated upon the notice required for annual meetings of stockholders and
shall be held at such place as specified in such notice. Any holder of Series B
Preferred Stock so designated shall have access to the stock books of the
Corporation relating to Series B Preferred Stock for the purpose of calling a

for the purpose of electing the director as provided in this Section 5(b), the
presence, in person or by proxy, of the holders of record of shares representing
at least a majority of the shares of the Series B Preferred Stock then
outstanding shall be required to constitute a quorum of the Series B Preferred
Stock for such election. The vacancy in the directorship to be elected by the
holders of Series B Preferred Stock pursuant to this Section 5(b) may be filled
only by vote or written consent in lieu of a meeting of the holders of at least
a majority of the voting power of the Series B Preferred Stock.

          (c) The Corporation shall not, without the affirmative consent or
approval of at least two-thirds of the shares of the Series B Preferred Stock
then outstanding, voting separately as a class:

               (1) in any manner authorize, create, designate, issue or sell any
          class or series of capital stock (including any shares of treasury
          stock) or rights, options, warrants or other securities convertible

          security which by its terms is convertible into or exchangeable for
          any equity security or has any other equity feature or any security
          that is a combination of debt and equity, which, in each case, as to
          the payment of dividends, distribution of assets or redemptions,
          including, without limitation, distributions to be made upon a
          Liquidation, is pari passu with or is senior to the Series B Preferred
          Stock or which in any manner adversely affects the holders of the
          Series B Preferred Stock;

               (2) in any manner alter or change the terms, designations,

               (3) create or issue shares of any class or series of capital
          stock, or reclassify the shares of any class or series of capital

          assets or redemptions, including, without limitation, distributions to
          be made upon a Liquidation, senior to or on a parity with such Series
          B Preferred Stock, or (B) which in any manner adversely affects the
          rights of the holders of such Series B Preferred Stock in their
          capacity as such;

               (4) take any action to cause any amendment, alteration or repeal
          of any of the provisions of (A) this Certificate of Incorporation or
          (B) the By-laws of the Corporation, if such

                                      -19-

               (7) agree to, or permit any subsidiary of the Corporation to

          Section 6. Conversion.

          (a) Upon the terms set forth in this Section 6, by surrender of the
certificate representing each share, each holder of each share of Series B
Preferred Stock shall have the right, at such holder's option, at any time and
from time to time, to convert all or any part of such shares into the number of
fully paid and nonassessable shares of Common Stock equal to the quotient
obtained by dividing (A) the Liquidation Amount of such share on the date of
such conversion by (B) the Conversion Price (as defined below), as last adjusted
and then in effect. The conversion price per share at which shares of Common
Stock shall be issuable upon conversion of shares of Series B Preferred Stock
shall be $0.86 (in each case, the "Conversion Price"), as adjusted pursuant to
paragraph (e) below. The holder of any shares of Series B Preferred Stock may
exercise the conversion right pursuant to this paragraph (a) by delivering to
the Corporation the certificate for the shares to be converted, duly endorsed or
assigned in blank or to the Corporation (if required by it), accompanied by
written notice stating that the holder elects to convert such shares and stating
the name or names (with address) in which the certificate or certificates for
the shares of Common Stock are to be issued. Conversion shall be deemed to have
been effected on the date when such delivery is made or upon the consummation of
a Qualified Public Offering as provided below, if applicable (as used in this
Article VI, the "Conversion Date").

          (b) Upon the terms set forth in this Section 6 upon the consummation
of a Qualified Public Offering or upon the election of the holders of at least
two-thirds of the shares of Series B Preferred Stock then outstanding, voting
together as a class, each share of Series B Preferred Stock shall automatically
be converted into that number of fully paid and nonassessable shares of Common
Stock equal to the quotient obtained by dividing (A) the Liquidation Amount of
such share on the earlier of (i) the date of such conversion and (ii) the date,
if any, which is selected by the Board so that any dividends accruing on the
Series B

                                      -21-



Preferred Stock after such date and prior to a Qualified Public Offering shall
be paid in cash following the Qualified Public Offering to the holders of record
immediately prior to such Qualified Public Offering, by (B) the applicable
Conversion Price, as last adjusted and then in effect.

          (c) As promptly as practicable after the conversion of any shares of
Series B Preferred Stock into Common Stock under paragraph (a) or (b) above, the
Corporation shall issue and deliver to or upon the written order of such holder,
to the place designated by such holder, a certificate or certificates for the
number of full shares of Common Stock to which such holder is entitled, and a
cash amount in respect of any fractional interest in a share of Common Stock as
provided in paragraph (d) below. The Person in whose name the certificate or
certificates for Common Stock are to be issued shall be deemed to have become a
stockholder of record on the applicable Conversion Date unless the transfer
books of the Corporation are closed on that date, in which event such Person
shall be deemed to have become a stockholder of record on the next succeeding
date on which the transfer books are open, but the Conversion Price shall be
that in effect on the Conversion Date, and the rights of the holder of the
shares of Series B Preferred Stock so converted shall cease on such Conversion
Date. Upon conversion of only a portion of the number of shares covered by a
certificate representing shares of Series B Preferred Stock surrendered for
conversion, the Corporation shall issue and deliver to or upon the written order
of the holder of the certificate so surrendered for conversion, at the expense
of the Corporation, a new certificate covering the number of shares of Series B
Preferred Stock representing the unconverted portion of the certificate so
surrendered.

          (d) No fractional shares of Common Stock or scrip shall be issued upon
conversion of shares of Series B Preferred Stock. The number of full shares of
Common Stock issuable upon conversion of Series B Preferred Stock shall be
computed on the basis of the aggregate number of shares of such preferred stock
to be converted. Instead of any fractional shares of Common Stock which would
otherwise be issuable upon conversion of any such shares, the Corporation shall
pay a cash adjustment in respect of such fractional interest in an amount equal
to the product of (A) the price of one share of Common Stock as determined in
good faith by the Board and (B) such fractional interest. The holders of
fractional interests shall not be entitled to any rights as stockholders of the
Corporation in respect of such fractional interests.

          (e) The Conversion Price shall be subject to adjustment from time to
time as follows:

               (1) If the Corporation shall, at any time or from time to time
          after the Original Issuance Date, issue any shares of Common Stock
          other than Excluded Stock without consideration or for a consideration
          per share less than the Conversion Price in effect immediately prior
          to the issuance of such Common Stock, then such Conversion Price, as
          in effect immediately prior to each such issuance, shall forthwith be
          lowered to a price equal to the quotient obtained by dividing:

                                      -22-



                    (i) an amount equal to the sum of (x) the total number of
               shares of Common Stock outstanding on a fully-diluted basis
               immediately prior to such issuance, multiplied by the Conversion
               Price in effect immediately prior to such issuance, and (y) the
               consideration received by the Corporation upon such issuance; by

                    (ii) the total number of shares of Common Stock outstanding
               on a fully-diluted basis immediately after the issuance of such
               Common Stock.

               (2) For the purposes of any adjustment of a Conversion Price
          pursuant to clause (1) above, the following provisions shall be
          applicable:

                    (i) In the case of the issuance of Common Stock for cash in
               a public offering or private placement, the consideration shall
               be deemed to be the amount of cash paid therefor after deducting
               therefrom any discounts, commissions or placement fees payable by
               the Corporation to any underwriter or placement agent in
               connection with the issuance and sale thereof.

                    (ii) In the case of the issuance of Common Stock for a
               consideration in whole or in part other than cash, the
               consideration other than cash shall be deemed to be the fair
               market value thereof as determined in good faith by the Board,
               irrespective of any accounting treatment.

                    (iii) In the case of the issuance of options to purchase or
               rights to subscribe for Common Stock, securities by their terms
               convertible into or exchangeable for Common Stock, or options to
               purchase or rights to subscribe for such convertible or
               exchangeable securities except for options to acquire Excluded
               Stock:

                         (A) the aggregate maximum number of shares of Common
                    Stock deliverable upon exercise of such options to purchase
                    or rights to subscribe for Common Stock shall be deemed to
                    have been issued at the time such options or rights were
                    issued and for a consideration equal to the consideration
                    (determined in the manner provided in subdivisions (e)(2)(i)
                    and (e)(2)(ii) above), if any, received by the Corporation
                    upon the issuance of such options or rights plus the minimum
                    purchase price provided in such options or rights for the
                    Common Stock covered thereby;

                         (B) 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 to purchase or rights to subscribe for
                    such

                                      -23-



                    convertible or exchangeable securities and subsequent
                    conversion or exchange thereof shall be deemed to have been
                    issued at the time such securities, options, or rights were
                    issued and for a consideration equal to the consideration
                    received by the Corporation for any such securities and
                    related options or 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 or the exercise of any related options or rights
                    (the consideration in each case to be determined in the
                    manner provided in subdivisions (e)(2)(i) and (e)(2)(ii)
                    above);

                         (C) on any change in the number of shares or exercise
                    price of Common Stock deliverable upon exercise of any such
                    options or rights or conversions of or exchanges for such
                    securities, other than a change resulting from the
                    antidilution provisions thereof, the Conversion Price shall
                    forthwith be readjusted to such Conversion Price as would
                    have been obtained had the adjustment made upon the issuance
                    of such options, rights or securities not converted prior to
                    such change, or options or rights related to such securities
                    not converted prior to such change, been made upon the basis
                    of such change;

                         (D) on the expiration of any such options or rights,
                    the termination of any such rights to convert or exchange or
                    the expiration of any options or rights related to such
                    convertible or exchangeable securities, the Conversion Price
                    shall forthwith be readjusted to such Conversion Price as
                    would have been obtained had the adjustment made upon the
                    issuance of such options, rights, securities or options or
                    rights related to such securities been made upon the basis
                    of the issuance of only the number of shares of Common Stock
                    actually issued upon the exercise of such options or rights,
                    upon the conversion or exchange of such securities, or upon
                    the exercise of the options or rights related to such
                    securities and subsequent conversion or exchange thereof;
                    and

                         (E) no further adjustment of the Conversion Price
                    adjusted upon the issuance of any such options, rights,
                    convertible securities or exchangeable securities shall be
                    made as a result of the actual issuance of Common Stock on
                    the exercise of any such rights or options or any conversion
                    or exchange of any such securities.

               (3) If, at any time after the Original Issuance Date, the number
          of shares of Common Stock outstanding is increased by a stock dividend
          payable in shares of Common Stock or by a subdivision or split-up of
          shares of Common Stock, then,

                                      -24-



          following the record date for the determination of holders of Common
          Stock entitled to receive such stock dividend, subdivision or
          split-up, the Conversion Price shall be appropriately decreased so
          that the number of shares of Common Stock issuable on conversion of
          each share of Series B Preferred Stock shall be increased in
          proportion to such increase in outstanding shares.

               (4) If, at any time after the Original Issuance Date, the number
          of shares of Common Stock outstanding is decreased by a combination of
          the outstanding shares of Common Stock (including, without limitation,
          as contemplated by the reverse stock split referred to in Section 4 of
          Article IV), then, following the record date for such combination, the
          Conversion Price shall be appropriately increased so that the number
          of shares of Common Stock issuable on conversion of each share of
          Series B Preferred Stock shall be decreased in proportion to such
          decrease in outstanding shares.

               (5) In the event of any capital reorganization of the
          Corporation, any reclassification of the stock of the Corporation
          (other than a change in par value or from par value to no par value or
          from no par value to par value or as a result of a stock dividend or
          subdivision, split-up or combination of shares), or any consolidation
          or merger of the Corporation, each share of Series B Preferred Stock
          shall after such reorganization, reclassification, consolidation, or
          merger be convertible into the kind and number of shares of stock or
          other securities or property of the Corporation or of the corporation
          resulting from such consolidation or surviving such merger to which
          the holder of the number of shares of Common Stock deliverable
          (immediately prior to the time of such reorganization,
          reclassification, consolidation or merger) upon conversion of such
          share of Series B Preferred Stock would have been entitled upon such
          reorganization, reclassification, consolidation or merger. The
          provisions of this clause shall similarly apply to successive
          reorganizations, reclassifications, consolidations or mergers.

               (6) No adjustment in any Conversion Price shall be required
          unless such adjustment would require an increase or decrease of at
          least $0.01 in such Conversion Price; provided, that any adjustments
          not required to be made by virtue of this sentence shall be carried
          forward and taken into account in any subsequent adjustment. All
          calculations under paragraphs (1) through (5) above shall be made to
          the nearest one hundredth (1/100) of a cent or the nearest one tenth
          (1/10) of a share, as the case may be.

                                      -25-



               (7) In any case in which the provisions of this paragraph (e)
          shall require that an adjustment shall become effective immediately
          after a record date of an event, the Corporation may defer until the
          occurrence of such event (1) issuing to the holder of any share of
          Series B Preferred Stock converted after such record date and before
          the occurrence of such event the shares of capital stock issuable upon
          such conversion by reason of the adjustment required by such event in
          addition to the shares of capital stock issuable upon such conversion
          before giving effect to such adjustments, and (2) paying to such
          holder any amount in cash in lieu of a fractional share of capital
          stock pursuant to paragraph (d) above; provided, however, that the
          Corporation shall deliver to such holder an appropriate instrument
          evidencing such holder's right to receive such additional shares and
          such cash.

               (8) Whenever a Conversion Price shall be adjusted as provided in
          paragraph (4), the Corporation shall make available for inspection
          during regular business hours, at its principal executive offices or
          at such other place as may be designated by the Corporation, a
          statement, signed by its chief executive officer, showing in detail
          the facts requiring such adjustment and the Conversion Price that
          shall be in effect after such adjustment. The Corporation shall also
          cause a copy of such statement to be sent by first class certified
          mail, return receipt requested and postage prepaid, to each holder of
          Series B Preferred Stock at such holder's address appearing on the
          Corporation's records. Where appropriate, such copy may be given in
          advance and may be included as part of any notice required to be
          mailed under the provisions of paragraph (9) below.

               (9) If the Corporation shall propose to take any action of the
          types described in clauses (3), (4) or (5) of this paragraph (e), the
          Corporation shall give notice to each holder of shares of Series B
          Preferred Stock, in the manner set forth in paragraph (8) above, which
          notice shall specify the record date, if any, with respect to any such
          action and the date on which such action is to take place. Such notice
          shall also set forth such facts with respect thereto as shall be
          reasonably necessary to indicate the effect of such action (to the
          extent such effect may be known at the date of such notice) on the
          Conversion Price and the number, kind or class of shares or other
          securities or property which shall be deliverable or purchasable upon
          the occurrence of such action or deliverable upon conversion of shares
          of Series B Preferred Stock. In the case of any action which would
          require the fixing of a record date, such notice shall be given at
          least 20 days prior to the date so fixed, and in case of all other
          action, such notice shall be given at least 30 days prior to the
          taking of such proposed action. Failure to give

                                      -26-



          such notice, or any defect therein, shall not affect the legality or
          validity of any such action.

               (10) The Corporation shall at all times keep reserved, free from
          preemptive rights, out of its authorized but unissued shares of Common
          Stock, solely for the purpose of effecting the conversion of the
          Series B Preferred Stock, sufficient shares of Common Stock to provide
          for the conversion of all outstanding shares of Series B Preferred
          Stock.

               (11) Without duplication of any other adjustment provided for in
          this Section 6, at any time the Corporation makes or fixes a record
          date for the determination of holders of Common Stock entitled to
          receive a dividend or other distribution payable in securities of the
          Corporation other than shares of Common Stock, provision shall be made
          so that each holder of Series B Preferred Stock shall receive upon
          conversion thereof, in addition to the shares of Common Stock
          receivable thereupon, the number of securities of the Corporation
          which it would have received had its shares of Series B Preferred
          Stock been converted into shares of Common Stock on the date of such
          event and had such holder thereafter, during the period from the date
          of such event to and including the date of conversion, retained such
          securities receivable by it pursuant to this paragraph during such
          period, subject to the sum of all other adjustments called for during
          such period under this Section 6 with respect to the rights of such
          holder of Series B Preferred Stock.

          Section 7. Definitions.

     As used in this Article VI, the following terms shall have the following
meanings:

          (a) "Applicable Dividend Rate" means 6% per annum.

          (b) "Arbitration Procedure", if applicable, means the following
procedure to determine the Fair Market Value (as used in this Article VI, the
"Valuation Amount"). The Valuation Amount shall be determined by an investment
banking firm of national standing in the United States, which firm shall be
reasonably acceptable to the Corporation and the holders of at least two thirds
of Series B Preferred Stock. If the Corporation and the holders of at least two
thirds of Series B Preferred Stock are unable to agree upon an acceptable
investment banking firm within 10 days after the date either party proposed that
one be selected, the investment banking firm will be selected by an arbitrator
located in the New York City, selected by the American Arbitration Association
in New York City (as used in this Article VI, the "Association") (or if such
organization ceases to exist, the arbitrator shall be chosen by a court of
competent jurisdiction in New York City). The arbitrator shall select the
investment banking firm (within 10 days of a request therefor from either the
Corporation or the holders of at least two thirds of Series B Preferred Stock)
from a list, jointly prepared by the Corporation and the

                                      -27-



holders of at least two thirds of Series B Preferred Stock, of not more than six
investment banking firms of national standing in the United States, of which no
more than three may be named by the Corporation and no more than three may be
named by the holders of at least two thirds of Series B Preferred Stock. The
arbitrator may consider, within the ten-day period allotted, arguments from the
parties regarding which investment banking firm to choose, but the selection by
the arbitrator shall be made in its sole discretion from the list of six. The
Corporation and the holders of at least two thirds of Series B Preferred Stock
shall submit to the investment banking firm selected by the arbitrator their
respective good faith calculations of the valuation amount, and any supporting
arguments and other data as they may desire, within 30 days of the appointment
of the investment banking firm, and the investment banking firm shall as soon as
practicable thereafter make its own calculation of the valuation amount. The
final valuation amount for purposes hereof shall be the average of the two
valuation amounts closest together, as determined by the investment banking
firm, from among the valuation amounts submitted by the Corporation and the
holders of at least two thirds of Series B Preferred Stock and the valuation
amount calculated by the investment banking firm. The determination of the final
valuation amount by such investment banking firm shall be final and binding upon
the parties. The Corporation shall pay the fees and expenses of the investment
banking firm, the Association and the arbitrator (if any) used to determine the
valuation amount. If required by any such investment banking firm or arbitrator,
the Corporation shall execute a retainer and engagement letter containing
reasonable terms and conditions, including, without limitation, customary
provisions concerning the rights of indemnification and contribution by the
Corporation in favor of such investment banking firm or arbitrator and its
officers, directors, partners, employees, agents and Affiliates.

of the Corporation or its subsidiaries pursuant to any equity incentive plan of
the Corporation and (2) shares of Common Stock issued upon conversion of shares
of the Series A Preferred Stock, the Series B Preferred Stock, the Series C
Preferred Stock and the Series D Preferred Stock.

Stock of the Corporation, the fair value of such share of Common Stock
determined by the mutual agreement of the Corporation and the holders of at
least two-thirds of Series B Preferred Stock. If such parties are unable to
reach agreement as to Fair Market Value within a reasonable period of time (not
to exceed 30 days), Fair Market Value shall be determined pursuant to the
Arbitration Procedure.

          (g) "Liquidation Amount" means as to each share of Series B Preferred
Stock, the Original Cost plus all accrued and unpaid dividends thereon through
the date of payment of such amount to the holder thereof (as adjusted for stock
splits, stock dividends and the like).

                                      -28-



          (h) "Liquidation Preference Payment" shall have the meaning ascribed
to it in Section 3(a).

          (i) "Original Cost" means with respect to each share of Series B
Preferred Stock $0.86 per share (as adjusted for stock splits, stock dividends
and the like).

          (j) "Original Issuance Date" shall be determined with respect to each

Corporation possessing a majority of the voting securities of the Corporation or
the surviving entity to such transaction or the voting power to elect a majority
of such subsidiaries board of directors or the board of directors (or similar
governing body) of the surviving entity (or similar governing body) (whether by
merger, consolidation or issuance, sale or transfer of such subsidiaries capital
stock) or (ii) all or substantially all of such subsidiary's assets determined
on a consolidated basis.

          (m) "Shared Allocation" means that the holders of Series D Preferred
Stock, Priority Preferred Stock, the holders of Series A Preferred Stock and the
holders of any other shares of any series or class of capital stock with
participation rights (the "Other Participating Securities") and Common Stock

to its stockholders in the same proportion as the number of shares of
outstanding Common Stock issuable upon the conversion of outstanding Series A
Preferred Stock, Series D Preferred Stock, Priority Preferred Stock and Other
Participating Securities then held by each such stockholder bears to the total

                            SERIES C PREFERRED STOCK

          Section 1. Number and Designation. Defined terms used in this Article
VII and not defined herein shall have the meaning ascribed to such terms in
Article IV of this Certificate

                                      -29-



of Incorporation. In addition, certain terms used in this Article VII are
defined in section 7 hereof.

     The shares of such series shall be designated as "Series C Convertible
Preferred Stock" and the number of shares constituting such series shall be
3,387,500.

          Section 2. Dividends.

          (a) The holders of the Series C Preferred Stock shall be entitled to
receive, when, as and if declared by the Board, out of funds legally available
for that purpose, dividends on each share of Series C Preferred Stock which
shall accrue on a daily basis at the Applicable Dividend Rate (compounded
annually on each anniversary of the Original Issuance Date), on the Liquidation
Amount, payable in cash. Dividends shall be cumulative and shall accrue at the
Applicable Dividend Rate on the Liquidation Amount regardless of whether the
Board has declared a dividend payment or whether there are any profits, surplus
or other funds of the Corporation legally available for dividends. Dividends
shall accrue pursuant to this Section 2 from and including the Original Issuance
Date to and including the date each share of Series C Preferred Stock is
redeemed in full. All payments or accruals due under this Section 2 to any
holder of Series C Preferred Stock shall be made or accrued to the nearest cent.

          (b) The dividends payable with respect to the Series C Preferred Stock
shall be paid to the holders of Series C Preferred Stock as they appear on the
stock records of the Corporation on such date as shall be fixed by the Board.

          (c) Except as otherwise provided herein, if at any time the
Corporation pays less than the total amount of dividends then accrued with
respect to the Series C Preferred Stock, such payment shall be distributed
ratably among the holders of Series C Preferred Stock based upon the number of
shares of Series C Preferred Stock held by each such holder.

          (d) In the event the Corporation shall fail to pay in full all accrued
dividends on all shares of Series C Preferred Stock, then the Corporation shall
not thereafter declare or pay or set apart for payment any dividend or other
distribution upon shares of Common Stock, or any other stock of the Corporation
ranking on a parity with or junior to the Series C Preferred Stock as to
dividends. The Series C Preferred Stock shall rank on a parity with the shares
of other Priority Preferred Stock, and shall rank prior and superior to the
shares of Series A Preferred Stock and Common Stock, with respect to dividends.

          (e) The holders of the Series C Preferred Stock and the holders of
other Priority Preferred Stock shall participate (on an as-converted basis) in
any and all dividend payments on the Common Stock when, as and if dividends are
paid with respect to the Common Stock.

          Section 3. Liquidation.

          (a) Upon any Liquidation of the Corporation, the holders of shares of
Series C Preferred Stock then outstanding shall be entitled to be paid out of
the assets of the Corporation available for distribution to its stockholders,
after the payment or provision for payment of debts and other liabilities of the
Corporation and after and subject to the payment in full of all amounts required
to be distributed to the holders of any other series or class of stock of the
Corporation ranking on Liquidation prior and in preference to the Series C
Preferred Stock upon such Liquidation, but on a parity with the other Priority
Preferred Stock and each other series or class of stock of the Corporation

                                      -30-



ranking on Liquidation on a parity with the Series C Preferred Stock, but before
any distribution or payment is made upon any common, preferred or any other
capital stock of the Corporation ranking on Liquidation junior to the Series C
Preferred Stock, an amount equal to the Liquidation Amount for each such share
of Series C Preferred Stock on the date of such Liquidation (such amount payable
with respect to one share of Series C Preferred Stock sometimes being referred
to in this Article VII as the "Liquidation Preference Payment" and with respect
to all shares of Series C Preferred Stock being sometimes referred to in this
Article VII as the "Liquidation Preference Payments").

          (b) If upon a Liquidation of the Corporation, the assets to be
distributed among the holders of Series C Preferred Stock shall be insufficient
to permit payment in full of the Liquidation Preference Payments to the holders
of Series C Preferred Stock, then the holders of the Series C Preferred Stock,
proportionately with the holders of other Priority Preferred Stock, shall share
in the entire assets of the Corporation to be so distributed in proportion to
the full Liquidation Preference Payment each such holder of Series C Preferred
Stock and other Priority Preferred Stock would otherwise be entitled to receive.
After the Liquidation Preference Payments shall have been made in full, the
remaining net assets of the Corporation available for distribution shall be
distributed (i) pursuant to the first sentence of Section 5(a) of Article V of
this Certificate of Incorporation (as used in this Article VII, the "Series A
Liquidation Preference Payment") and (ii) after the payment or distribution in
full of the Series A Liquidation Preference Payment, the remaining net assets of
the Corporation shall be distributed as a Shared Allocation.

          (c) Written notice of such Liquidation, stating a payment date, the
amount of the Liquidation Preference Payments, and the place where said
Liquidation Preference Payments shall be payable, shall be delivered in person,
mailed by certified or registered mail, return receipt requested, or sent by
telecopier or telex, not less than 20 days prior to the payment date stated
therein, to the holders of record of Series C Preferred Stock. Such notice shall
be addressed to each such holder at its address as shown by the records of the
Corporation.

          Section 4. Redemption.

          (a) Upon the election of the holders of at least two-thirds of the
shares of Series C Preferred Stock and other Priority Preferred Stock and Series
D Preferred Stock, in the aggregate, then outstanding, voting together as a
class (calculated on an as-converted basis), the holders of such shares shall
have the right to require the Corporation to redeem all or a portion of such
shares on a date (as used in this Article VII, the "Redemption Date") on or at
any time after February 8, 2005 for the Series B Preferred Stock, at any time
after May 16, 2005 for the Series C Preferred Stock and on or at any time after
February 8, 2005 for the Series D Preferred Stock, upon not less than 15 days
prior written notice. At least 10 days prior to the Redemption Date, the
Corporation shall notify each respective holder of Series C Preferred Stock and
other Priority Preferred Stock and Series D Preferred Stock of such holder's
right of optional redemption under this Section 4. Each holder of Series C
Preferred Stock or other Priority Preferred Stock or Series D Preferred Stock
may elect its preference to have its shares, or any portion thereof, redeemed
under this Section 4(a) by notifying the Corporation of such election; provided,
however, that the Corporation shall only be required to redeem such shares if
the holders of a

                                      -31-



least two-thirds of the shares of Series C Preferred Stock and other Priority
Preferred Stock and Series D Preferred Stock, in the aggregate (calculated on an
as-converted basis), elect to have at least two-thirds of the shares of Series C
Preferred Stock and other Priority Preferred Stock and Series D Preferred Stock
redeemed. If the assets of the Corporation available for redemption of the
Series C Preferred Stock and other Priority Preferred Stock and Series D
Preferred Stock shall be insufficient to permit the payment of the full price
required to be paid under this Section 4, then the holders of Series C Preferred
Stock and other Priority Preferred Stock and Series D Preferred Stock shall
share ratably in any such redemption according to the respective amounts which
would be payable in respect of the number of shares that such holders own if all
amounts payable on or with respect to such shares were paid in full.

          (b) On and after any Redemption Date, all rights in respect of the
shares of Series C Preferred Stock to be redeemed on such Redemption Date,
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 Corporation;
provided, however, that if default shall be made by the Corporation in the
payment of the Redemption Price, such rights shall remain in full force and
effect and be exercisable, and such shares shall be deemed to remain
outstanding, until such default is cured.

          (c) Anything contained in this Section 4 to the contrary
notwithstanding, the holders of shares of Series C Preferred Stock and other
Priority Preferred Stock and Series D Preferred Stock requested by such holders
as herein provided to be redeemed pursuant to this Section 4 shall have no
right, after such request, to convert all or any part of such shares to be
redeemed as herein provided into shares of Common Stock pursuant to Section 6
hereof; provided, however, that if default shall be made by the Corporation in
the payment of the Redemption Price as herein provided, such right shall be
exercisable until such default is cured. If and to the extent, any shares of
Series C Preferred Stock and other Priority Preferred Stock and Series D
Preferred Stock so entitled to redemption are converted into shares of Common
Stock by the holders thereof prior to the close of business on the Redemption
Date, the total number of shares of Series C Preferred Stock and other Priority
Preferred Stock and Series D Preferred Stock otherwise to be redeemed on such
date shall be reduced by the number of shares of Series C Preferred Stock and
other Priority Preferred Stock and Series D Preferred Stock so converted.

          (d) To the extent that on any Redemption Date the Corporation is not
legally permitted (by Delaware law, this Certificate of Incorporation, its
By-laws, contractual provisions or otherwise) to pay the Redemption Price of any
shares of Series C Preferred Stock required to be redeemed by the Corporation on
such Redemption Date, the Corporation shall promptly take all action (including,
without limitation, a revaluation of assets or a prepayment of indebtedness
restricting such redemption) as may be permitted by applicable law to permit
such redemption in full. If the Corporation remains unable after the taking of
such action to repurchase any or all of such shares, the Corporation shall
immediately repurchase such shares upon the termination of such legal
prohibition.

          (e) The price (as used in this Article VII, the "Redemption Price") at
which each share of Series C Preferred Stock is to be redeemed by the
Corporation pursuant to this Section 4 shall be equal to the greater of (i) the
Liquidation Amount of such share on the date of such redemption and (ii) the
Fair Market Value of such share on the date of redemption. The

                                      -32-



conversion of any shares of the Series C Preferred Stock into Common Stock shall
have no effect on the Redemption Price payable in connection with the redemption
of the shares of Series C Preferred Stock not so converted.

          (f) Any communication or notice relating to redemption given pursuant
to this Section 4 shall be sent by first-class certified mail, return receipt
requested, postage prepaid, to the holders of record of shares of Series C
Preferred Stock, at their respective addresses as the same shall appear on the
books of the Corporation, or to the Corporation at the address of its principal,
or registered office, as the case may be. At any time on or after the Redemption
Date, the holders of record of shares of Series C Preferred Stock being redeemed
in accordance with this Section 4 shall be entitled to receive the Redemption
Price as determined upon actual delivery to the Corporation or its agents of the
certificates representing the shares to be redeemed.

          Section 5. Voting Rights.

          (a) In addition to the rights provided by law or in the Corporation's
By-laws, each share of Series C Preferred Stock shall entitle the holder thereof
to such number of votes as shall equal the number of shares of Common Stock into
which such share of Series C Preferred Stock is then convertible pursuant to
Section 6 at the record date for the determination of stockholders entitled to
vote or, if no record date is established, at the date such vote is taken. In
addition to class or series voting rights provided by law or in this Certificate
of Incorporation, the holders of Series C Preferred Stock shall be entitled to
vote on all matters as to which holders of Common Stock shall be entitled to
vote in the same manner and with the same effect as such holders of Common
Stock, voting together with the holders of Common Stock, the holders of the
Series A Preferred Stock (calculated on an as-converted basis ) and the holders
of other Priority Preferred Stock (calculated on an as-converted basis) as one
class.

          (b) The Corporation shall not, without the affirmative consent or
approval of the holders of a majority of the shares of the Series C Preferred
Stock then outstanding, voting together as a class, amend the Certificate of
Incorporation of the Corporation in any way that adversely affects the
conversion terms of the Series C Preferred Stock.

          Section 6. Conversion.

          (a) Upon the terms set forth in this Section 6, by surrender of the
certificate representing each share, each holder of each share of Series C
Preferred Stock shall have the right, at such holder's option, at any time and
from time to time, to convert all or any part of such shares into the number of
fully paid and nonassessable shares of Common Stock equal to the quotient
obtained by dividing (A) the Liquidation Amount of such share on the date of
such conversion by (B) the Conversion Price (as defined below), as last adjusted
and then in effect. The conversion price per share at which shares of Common
Stock shall be issuable upon conversion of shares of Series C Preferred Stock
shall be $1.00 (in each case, the "Conversion Price"), as adjusted pursuant to
paragraph (e) below. The holder of any shares of Series C Preferred Stock may
exercise the conversion right pursuant to this paragraph (a) by delivering to
the Corporation the certificate for the shares to be converted, duly endorsed or
assigned in blank or to the Corporation (if required by it), accompanied by
written notice stating that the holder

                                      -33-



elects to convert such shares and stating the name or names (with address) in
which the certificate or certificates for the shares of Common Stock are to be
issued. Conversion shall be deemed to have been effected on the date when such
delivery is made or upon the consummation of a Qualified Public Offering as
provided below, if applicable (as used in this Article VII, the "Conversion
Date").

          (b) Upon the terms set forth in this Section 6 upon the consummation
of a Qualified Public Offering or upon the election of the holders of at least
two-thirds of the shares of Series C Preferred Stock then outstanding, voting
together as a class, each share of Series C Preferred Stock shall automatically
be converted into that number of fully paid and nonassessable shares of Common
Stock equal to the quotient obtained by dividing (A) the Liquidation Amount of
such share on the earlier of (i) the date of such conversion and (ii) the date,
if any, which is selected by the Board so that any dividends accruing on the
Series C Preferred Stock after such date and prior to a Qualified Public
Offering shall be paid in cash following the Qualified Public Offering to the
holders of record immediately prior to such Qualified Public Offering, by (B)
the applicable Conversion Price, as last adjusted and then in effect.

          (c) As promptly as practicable after the conversion of any shares of
Series C Preferred Stock into Common Stock under paragraph (a) or (b) above, the
Corporation shall issue and deliver to or upon the written order of such holder,
to the place designated by such holder, a certificate or certificates for the
number of full shares of Common Stock to which such holder is entitled, and a
cash amount in respect of any fractional interest in a share of Common Stock as
provided in paragraph (d) below. The Person in whose name the certificate or
certificates for Common Stock are to be issued shall be deemed to have become a
stockholder of record on the applicable Conversion Date unless the transfer
books of the Corporation are closed on that date, in which event such Person
shall be deemed to have become a stockholder of record on the next succeeding
date on which the transfer books are open, but the Conversion Price shall be
that in effect on the Conversion Date, and the rights of the holder of the
shares of Series C Preferred Stock so converted shall cease on such Conversion
Date. Upon conversion of only a portion of the number of shares covered by a
certificate representing shares of Series C Preferred Stock surrendered for
conversion, the Corporation shall issue and deliver to or upon the written order
of the holder of the certificate so surrendered for conversion, at the expense
of the Corporation, a new certificate covering the number of shares of Series C
Preferred Stock representing the unconverted portion of the certificate so
surrendered.

          (d) No fractional shares of Common Stock or scrip shall be issued upon
conversion of shares of Series C Preferred Stock. The number of full shares of
Common Stock issuable upon conversion of Series C Preferred Stock shall be
computed on the basis of the aggregate number of shares of such preferred stock
to be converted. Instead of any fractional shares of Common Stock which would
otherwise be issuable upon conversion of any such shares, the Corporation shall
pay a cash adjustment in respect of such fractional interest in an amount equal
to the product of (A) the price of one share of Common Stock as determined in
good faith by the Board and (B) such fractional interest. The holders of
fractional interests shall not be entitled to any rights as stockholders of the
Corporation in respect of such fractional interests.

                                      -34-



          (e) The Conversion Price shall be subject to adjustment from time to
time as follows:

               (1) If the Corporation shall, at any time or from time to time
          after the Original Issuance Date, issue any shares of Common Stock
          other than Excluded Stock without consideration or for a consideration
          per share less than the Conversion Price in effect immediately prior
          to the issuance of such Common Stock, then such Conversion Price, as
          in effect immediately prior to each such issuance, shall forthwith be
          lowered to a price equal to the quotient obtained by dividing:

                    (i) an amount equal to the sum of (x) the total number of
               shares of Common Stock outstanding on a fully-diluted basis
               immediately prior to such issuance, multiplied by the Conversion
               Price in effect immediately prior to such issuance, and (y) the
               consideration received by the Corporation upon such issuance; by

                    (ii) the total number of shares of Common Stock outstanding
               on a fully-diluted basis immediately after the issuance of such
               Common Stock.

               (2) For the purposes of any adjustment of a Conversion Price
          pursuant to clause (1) above, the following provisions shall be
          applicable:

                    (i) In the case of the issuance of Common Stock for cash in
               a public offering or private placement, the consideration shall
               be deemed to be the amount of cash paid therefor after deducting
               therefrom any discounts, commissions or placement fees payable by
               the Corporation to any underwriter or placement agent in
               connection with the issuance and sale thereof.

                    (ii) In the case of the issuance of Common Stock for a
               consideration in whole or in part other than cash, the
               consideration other than cash shall be deemed to be the fair
               market value thereof as determined in good faith by the Board,
               irrespective of any accounting treatment.

                    (iii) In the case of the issuance of options to purchase or
               rights to subscribe for Common Stock, securities by their terms
               convertible into or exchangeable for Common Stock, or options to
               purchase or rights to subscribe for such convertible or
               exchangeable securities except for options to acquire Excluded
               Stock:

                         (A) the aggregate maximum number of shares of Common
                    Stock deliverable upon exercise of such options to purchase
                    or rights to subscribe for Common Stock shall be deemed

                                      -35-



                    to have been issued at the time such options or rights were
                    issued and for a consideration equal to the consideration
                    (determined in the manner provided in subdivisions (e)(2)(i)
                    and (e)(2)(ii) above), if any, received by the Corporation
                    upon the issuance of such options or rights plus the minimum
                    purchase price provided in such options or rights for the
                    Common Stock covered thereby;

                         (B) 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 to purchase or rights to subscribe for
                    such convertible or exchangeable securities and subsequent
                    conversion or exchange thereof shall be deemed to have been
                    issued at the time such securities, options, or rights were
                    issued and for a consideration equal to the consideration
                    received by the Corporation for any such securities and
                    related options or 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 or the exercise of any related options or rights
                    (the consideration in each case to be determined in the
                    manner provided in subdivisions (e)(2)(i) and (e)(2)(ii)
                    above);

                         (C) on any change in the number of shares or exercise
                    price of Common Stock deliverable upon exercise of any such
                    options or rights or conversions of or exchanges for such
                    securities, other than a change resulting from the
                    antidilution provisions thereof, the Conversion Price shall
                    forthwith be readjusted to such Conversion Price as would
                    have been obtained had the adjustment made upon the issuance
                    of such options, rights or securities not converted prior to
                    such change, or options or rights related to such securities
                    not converted prior to such change, been made upon the basis
                    of such change;

                         (D) on the expiration of any such options or rights,
                    the termination of any such rights to convert or exchange or
                    the expiration of any options or rights related to such
                    convertible or exchangeable securities, the Conversion Price
                    shall forthwith be readjusted to such Conversion Price as
                    would have been obtained had the adjustment made upon the
                    issuance of such options, rights, securities or options or
                    rights related to such securities been made upon the basis
                    of the issuance of only the number of shares of Common Stock
                    actually issued upon the exercise of such options or rights,
                    upon the conversion or exchange of such securities, or upon
                    the exercise of the options or rights related to such
                    securities and subsequent conversion or exchange thereof;
                    and

                                      -36-



                         (E) no further adjustment of the Conversion Price
                    adjusted upon the issuance of any such options, rights,
                    convertible securities or exchangeable securities shall be
                    made as a result of the actual issuance of Common Stock on
                    the exercise of any such rights or options or any conversion
                    or exchange of any such securities.

               (3) If, at any time after the Original Issuance Date, the number
          of shares of Common Stock outstanding is increased by a stock dividend
          payable in shares of Common Stock or by a subdivision or split-up of
          shares of Common Stock, then, following the record date for the
          determination of holders of Common Stock entitled to receive such
          stock dividend, subdivision or split-up, the Conversion Price shall be
          appropriately decreased so that the number of shares of Common Stock
          issuable on conversion of each share of Series C Preferred Stock shall
          be increased in proportion to such increase in outstanding shares.

               (4) If, at any time after the Original Issuance Date, the number
          of shares of Common Stock outstanding is decreased by a combination of
          the outstanding shares of Common Stock (including, without limitation,
          as contemplated by the reverse stock split referred to in Section 4 of
          Article IV), then, following the record date for such combination, the
          Conversion Price shall be appropriately increased so that the number
          of shares of Common Stock issuable on conversion of each share of
          Series C Preferred Stock shall be decreased in proportion to such
          decrease in outstanding shares.

               (5) In the event of any capital reorganization of the
          Corporation, any reclassification of the stock of the Corporation
          (other than a change in par value or from par value to no par value or
          from no par value to par value or as a result of a stock dividend or
          subdivision, split-up or combination of shares), or any consolidation
          or merger of the Corporation, each share of Series C Preferred Stock
          shall after such reorganization, reclassification, consolidation, or
          merger be convertible into the kind and number of shares of stock or
          other securities or property of the Corporation or of the corporation
          resulting from such consolidation or surviving such merger to which
          the holder of the number of shares of Common Stock deliverable
          (immediately prior to the time of such reorganization,
          reclassification, consolidation or merger) upon conversion of such
          share of Series C Preferred Stock would have been entitled upon such
          reorganization, reclassification, consolidation or merger. The
          provisions of this clause shall similarly apply to successive
          reorganizations, reclassifications, consolidations or mergers.

                                      -37-



               (6) No adjustment in any Conversion Price shall be required
          unless such adjustment would require an increase or decrease of at
          least $0.01 in such Conversion Price; provided, that any adjustments
          not required to be made by virtue of this sentence shall be carried
          forward and taken into account in any subsequent adjustment. All
          calculations under paragraphs (1) through (5) above shall be made to
          the nearest one hundredth (1/100) of a cent or the nearest one tenth
          (1/10) of a share, as the case may be.

               (7) In any case in which the provisions of this paragraph (e)
          shall require that an adjustment shall become effective immediately
          after a record date of an event, the Corporation may defer until the
          occurrence of such event (1) issuing to the holder of any share of
          Series C Preferred Stock converted after such record date and before
          the occurrence of such event the shares of capital stock issuable upon
          such conversion by reason of the adjustment required by such event in
          addition to the shares of capital stock issuable upon such conversion
          before giving effect to such adjustments, and (2) paying to such
          holder any amount in cash in lieu of a fractional share of capital
          stock pursuant to paragraph (d) above; provided, however, that the
          Corporation shall deliver to such holder an appropriate instrument
          evidencing such holder's right to receive such additional shares and
          such cash.

               (8) Whenever a Conversion Price shall be adjusted as provided in
          paragraph (4), the Corporation shall make available for inspection
          during regular business hours, at its principal executive offices or
          at such other place as may be designated by the Corporation, a
          statement, signed by its chief executive officer, showing in detail
          the facts requiring such adjustment and the Conversion Price that
          shall be in effect after such adjustment. The Corporation shall also
          cause a copy of such statement to be sent by first class certified
          mail, return receipt requested and postage prepaid, to each holder of
          Series C Preferred Stock at such holder's address appearing on the
          Corporation's records. Where appropriate, such copy may be given in
          advance and may be included as part of any notice required to be
          mailed under the provisions of paragraph (9) below.

               (9) If the Corporation shall propose to take any action of the
          types described in clauses (3), (4) or (5) of this paragraph (e), the
          Corporation shall give notice to each holder of shares of Series C
          Preferred Stock, in the manner set forth in paragraph (8) above, which
          notice shall specify the record date, if any, with respect to any such
          action and the date on which such action is to take place. Such notice
          shall also set forth such facts with respect thereto as shall be
          reasonably necessary to indicate the effect of such action

                                      -38-



          (to the extent such effect may be known at the date of such notice) on
          the Conversion Price and the number, kind or class of shares or other
          securities or property which shall be deliverable or purchasable upon
          the occurrence of such action or deliverable upon conversion of shares
          of Series C Preferred Stock. In the case of any action which would
          require the fixing of a record date, such notice shall be given at
          least 20 days prior to the date so fixed, and in case of all other
          action, such notice shall be given at least 30 days prior to the
          taking of such proposed action. Failure to give such notice, or any
          defect therein, shall not affect the legality or validity of any such
          action.

               (10) The Corporation shall at all times keep reserved, free from
          preemptive rights, out of its authorized but unissued shares of Common
          Stock, solely for the purpose of effecting the conversion of the
          Series C Preferred Stock, sufficient shares of Common Stock to provide
          for the conversion of all outstanding shares of Series C Preferred
          Stock.

               (11) Without duplication of any other adjustment provided for in
          this Section 6, at any time the Corporation makes or fixes a record
          date for the determination of holders of Common Stock entitled to
          receive a dividend or other distribution payable in securities of the
          Corporation other than shares of Common Stock, provision shall be made
          so that each holder of Series C Preferred Stock shall receive upon
          conversion thereof, in addition to the shares of Common Stock
          receivable thereupon, the number of securities of the Corporation
          which it would have received had its shares of Series C Preferred
          Stock been converted into shares of Common Stock on the date of such
          event and had such holder thereafter, during the period from the date
          of such event to and including the date of conversion, retained such
          securities receivable by it pursuant to this paragraph during such
          period, subject to the sum of all other adjustments called for during
          such period under this Section 6 with respect to the rights of such
          holder of Series C Preferred Stock.

          Section 7. Definitions.

     As used in this Article VII, the following terms shall have the following
meanings:

          (a) "Applicable Dividend Rate" means 6% per annum.

          (b) "Arbitration Procedure", if applicable, means the following
procedure to determine the Fair Market Value (as used in this Article VII, the
"Valuation Amount"). The Valuation Amount shall be determined by an investment
banking firm of national standing in the United States, which firm shall be
reasonably acceptable to the Corporation and the holders of at

                                      -39-



least two thirds of Series C Preferred Stock. If the Corporation and the holders
of at least two thirds of Series C Preferred Stock are unable to agree upon an
acceptable investment banking firm within 10 days after the date either party
proposed that one be selected, the investment banking firm will be selected by
an arbitrator located in the New York City, selected by the American Arbitration
Association in New York City (as used in this Article VII, the "Association")
(or if such organization ceases to exist, the arbitrator shall be chosen by a
court of competent jurisdiction in New York City). The arbitrator shall select
the investment banking firm (within 10 days of a request therefor from either
the Corporation or the holders of at least two thirds of Series C Preferred
Stock) from a list, jointly prepared by the Corporation and the holders of at
least two thirds of Series C Preferred Stock, of not more than six investment
banking firms of national standing in the United States, of which no more than
three may be named by the Corporation and no more than three may be named by the
holders of at least two thirds of Series C Preferred Stock. The arbitrator may
consider, within the ten-day period allotted, arguments from the parties
regarding which investment banking firm to choose, but the selection by the
arbitrator shall be made in its sole discretion from the list of six. The
Corporation and the holders of at least two thirds of Series C Preferred Stock
shall submit to the investment banking firm selected by the arbitrator their
respective good faith calculations of the valuation amount, and any supporting
arguments and other data as they may desire, within 30 days of the appointment
of the investment banking firm, and the investment banking firm shall as soon as
practicable thereafter make its own calculation of the valuation amount. The
final valuation amount for purposes hereof shall be the average of the two
valuation amounts closest together, as determined by the investment banking
firm, from among the valuation amounts submitted by the Corporation and the
holders of at least two thirds of Series C Preferred Stock and the valuation
amount calculated by the investment banking firm. The determination of the final
valuation amount by such investment banking firm shall be final and binding upon
the parties. The Corporation shall pay the fees and expenses of the investment
banking firm, the Association and the arbitrator (if any) used to determine the
valuation amount. If required by any such investment banking firm or arbitrator,
the Corporation shall execute a retainer and engagement letter containing
reasonable terms and conditions, including, without limitation, customary
provisions concerning the rights of indemnification and contribution by the
Corporation in favor of such investment banking firm or arbitrator and its
officers, directors, partners, employees, agents and Affiliates.

          (c) "Conversion Date" shall have the meaning ascribed to it in Section
6(a).

          (d) "Conversion Price" shall have the meaning ascribed to it in
Section 6(b).

          (e) "Excluded Stock" means (1) up to 7,500,000 shares (as adjusted

of the Corporation or its subsidiaries pursuant to any equity incentive plan of
the Corporation and (2) shares of Common Stock issued upon conversion of shares
of the Series A Preferred Stock, the Series B Preferred Stock, the Series C
Preferred Stock and the Series D Preferred Stock.

          (f) "Fair Market Value" means, with respect to any share of Common
Stock of the Corporation, the fair value of such share of Common Stock
determined by the mutual

                                      -40-



agreement of the Corporation and the holders of at least two-thirds of Series C
Preferred Stock. If such parties are unable to reach agreement as to Fair Market
Value within a reasonable period of time (not to exceed 30 days), Fair Market
Value shall be determined pursuant to the Arbitration Procedure.

          (g) "Liquidation Amount" means as to each share of Series C Preferred
Stock, the Original Cost plus all accrued and unpaid dividends thereon through
the date of payment of such amount to the holder thereof (as adjusted for stock
splits, stock dividends and the like).

          (h) "Liquidation Preference Payment" shall have the meaning ascribed
to it in Section 3(a).

          (i) "Original Cost" means with respect to each share of Series C
Preferred Stock $1.00 per share (as adjusted for stock splits, stock dividends
and the like).

          (j) "Original Issuance Date" shall be determined with respect to each
share of Series C Preferred Stock separately and shall mean the date that the
Corporation received full payment in cash for such share of Series C Preferred
Stock.

          (k) "Qualified Public Offering" means a public offering of securities
of the Corporation underwritten on a firm basis by an underwriter reasonably
satisfactory to the holders of at least a majority of the Priority Preferred

by such an underwriter), yielding gross proceeds to the Corporation (before
deducting underwriter's discounts and commissions and other expenses) of not
less than $15,000,000.

          (l) "Shared Allocation" means that the holders of Series D Preferred
Stock, Priority Preferred Stock, the holders of Series A Preferred Stock and the
holders of any other shares of any series or class of capital stock with
participation rights (the "Other Participating Securities") and Common Stock
shall share the remaining assets of the Corporation available for distribution
to its stockholders in the same proportion as the number of shares of
outstanding Common Stock issuable upon the conversion of outstanding Series A
Preferred Stock, Series D Preferred Stock, Priority Preferred Stock and Other
Participating Securities then held by each such stockholder bears to the total
number of shares of outstanding Common Stock plus the Common Stock issuable upon
conversion of outstanding Series A Preferred Stock, Series D Preferred Stock,
Priority Preferred Stock and Other Participating Securities.

                                  ARTICLE VIII

                            SERIES D PREFERRED STOCK

          Section 1. Number and Designation. Defined terms used in this Article
VIII and not defined herein shall have the meaning ascribed to such terms in
Article IV of this Certificate of Incorporation. In addition, certain terms used
in this Article VIII are defined in section 7 hereof.

     The shares of such series shall be designated as "Series D Convertible
Preferred Stock" and the number of shares constituting such series shall be
20,000,000.

                                      -41-



          Section 2. Dividends.

          (a) The holders of the Series D Preferred Stock shall be entitled to
receive, when, as and if declared by the Board, out of funds legally available
for that purpose, dividends on each share of Series D Preferred Stock which
shall accrue on a daily basis at the Applicable Dividend Rate (compounded
annually on each anniversary of the Original Issuance Date), on the Liquidation
Amount, payable in cash. Dividends shall be cumulative and shall accrue at the
Applicable Dividend Rate on the Liquidation Amount regardless of whether the
Board has declared a dividend payment or whether there are any profits, surplus
or other funds of the Corporation legally available for dividends. Dividends
shall accrue pursuant to this Section 2 from and including the Original Issuance
Date to and including the date each share of Series D Preferred Stock is
redeemed in full. All payments or accruals due under this Section 2 to any
holder of Series D Preferred Stock shall be made or accrued to the nearest cent.

          (b) The dividends payable with respect to the Series D Preferred Stock
shall be paid to the holders of Series D Preferred Stock as they appear on the
stock records of the Corporation on such date as shall be fixed by the Board.

          (c) Except as otherwise provided herein, if at any time the
Corporation pays less than the total amount of dividends then accrued with
respect to the Series D Preferred Stock, such payment shall be distributed
ratably among the holders of Series D Preferred Stock based upon the number of
shares of Series D Preferred Stock held by each such holder.

          (d) In the event the Corporation shall fail to pay in full all accrued
dividends on all shares of Series D Preferred Stock, then the Corporation shall
not thereafter declare or pay or set apart for payment any dividend or other
distribution upon shares of Common Stock, or any other stock of the Corporation
ranking on a parity with or junior to the Series D Preferred Stock as to
dividends. The Series D Preferred Stock shall rank prior and superior to the
shares of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred
Stock and Common Stock, with respect to dividends.

          (e) The holders of the Series D Preferred Stock and the holders of
Priority Preferred Stock shall participate (on an as-converted basis) in any and
all dividend payments on the Common Stock when, as and if dividends are paid
with respect to the Common Stock.

          Section 3. Liquidation.

          (a) Upon any Liquidation of the Corporation, the holders of shares of
Series D Preferred Stock then outstanding shall be entitled to be paid out of
the assets of the Corporation available for distribution to its stockholders,
after the payment or provision for payment of debts and other liabilities of the
Corporation and after and subject to the payment in full of all amounts required
to be distributed to the holders of any other series or class of stock of the
Corporation ranking on Liquidation prior and in preference to the Series D
Preferred Stock upon such Liquidation, but before any distribution or payment is
made upon any common, preferred or any other capital stock of the Corporation
ranking on Liquidation junior to the Series D Preferred Stock, an amount equal
to the Liquidation Amount for each such share of Series D Preferred Stock on the
date of such Liquidation (such amount payable with respect to one share of
Series D

                                      -42-



Preferred Stock sometimes being referred to in this Article VIII as the
"Liquidation Preference Payment" and with respect to all shares of Series D
Preferred Stock being sometimes referred to in this Article VIII as the
"Liquidation Preference Payments").

          (b) If upon a Liquidation of the Corporation, the assets to be
distributed among the holders of Series D Preferred Stock shall be insufficient
to permit payment in full of the Liquidation Preference Payments to the holders
of Series D Preferred Stock, then the holders of the Series D Preferred Stock
shall share in the entire assets of the Corporation to be so distributed in
proportion to the full Liquidation Preference Payment each such holder of Series
D Preferred Stock would otherwise be entitled to receive. After the Liquidation
Preference Payments shall have been made in full, the remaining net assets of
the Corporation available for distribution shall be distributed (i) pursuant to
Section 3(a) of Article VI and Section 3(a) of Article VII of this Certificate
of Incorporation, (ii) pursuant to the first sentence of Section 5(a) of Article
V of this Certificate of Incorporation (as used in this Article VIII, the
"Series A Liquidation Preference Payment") and (iii) after the payment or
distribution in full of the Series A Liquidation Preference Payment, the
remaining net assets of the Corporation shall be distributed as a Shared
Allocation.

          (c) Written notice of such Liquidation, stating a payment date, the
amount of the Liquidation Preference Payments, and the place where said
Liquidation Preference Payments shall be payable, shall be delivered in person,
mailed by certified or registered mail, return receipt requested, or sent by
telecopier or telex, not less than 20 days prior to the payment date stated
therein, to the holders of record of Series D Preferred Stock. Such notice shall
be addressed to each such holder at its address as shown by the records of the
Corporation.

          Section 4. Redemption.

          (a) Upon the election of the holders of at least two-thirds of the
shares of Series D Preferred Stock and Priority Preferred Stock, in the
aggregate, then outstanding, voting together as a class (calculated on an
as-converted basis), the holders of such shares shall have the right to require
the Corporation to redeem all or a portion of such shares on a date (as used in
this Article VIII, the "Redemption Date") on or at any time after February 8,
2005 for the Series B Preferred Stock, at any time after May 16, 2005 for the
Series C Preferred Stock and on or at any time after February 8, 2005 for the
Series D Preferred Stock, upon not less than 15 days prior written notice. At
least 10 days prior to the Redemption Date, the Corporation shall notify each
respective holder of Series D Preferred Stock and Priority Preferred Stock of
such holder's right of optional redemption under this Section 4. Each holder of
Series D Preferred Stock or Priority Preferred Stock may elect its preference to
have its shares, or any portion thereof, redeemed under this Section 4(a) by
notifying the Corporation of such election; provided, however, that the
Corporation shall only be required to redeem such shares if the holders of a
least two-thirds of the shares of Series D Preferred Stock and Priority
Preferred Stock, in the aggregate (calculated on an as-converted basis), elect
to have at least two-thirds of the shares of Series D Preferred Stock and
Priority Preferred Stock redeemed. If the assets of the Corporation available
for redemption of the Series D Preferred Stock and Priority Preferred Stock
shall be insufficient to permit the payment of the full price required to be
paid under this Section 4, then the holders of Series D Preferred Stock and
Priority Preferred Stock shall share ratably in any such redemption

                                      -43-



according to the respective amounts which would be payable in respect of the
number of shares that such holders own if all amounts payable on or with respect
to such shares were paid in full.

          (b) On and after any Redemption Date, all rights in respect of the
shares of Series D Preferred Stock to be redeemed on such Redemption Date,
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 Corporation;
provided, however, that if default shall be made by the Corporation in the
payment of the Redemption Price, such rights shall remain in full force and
effect and be exercisable, and such shares shall be deemed to remain
outstanding, until such default is cured.

          (c) Anything contained in this Section 4 to the contrary
notwithstanding, the holders of shares of Series D Preferred Stock and Priority
Preferred Stock requested by such holders as herein provided to be redeemed
pursuant to this Section 4 shall have no right, after such request, to convert
all or any part of such shares to be redeemed as herein provided into shares of
Common Stock pursuant to Section 6 hereof; provided, however, that if default
shall be made by the Corporation in the payment of the Redemption Price as
herein provided, such right shall be exercisable until such default is cured. If
and to the extent, any shares of Series D Preferred Stock and Priority Preferred
Stock so entitled to redemption are converted into shares of Common Stock by the
holders thereof prior to the close of business on the Redemption Date, the total
number of shares of Series D Preferred Stock and Priority Preferred Stock
otherwise to be redeemed on such date shall be reduced by the number of shares
of Series D Preferred Stock and Priority Preferred Stock so converted.

          (d) To the extent that on any Redemption Date the Corporation is not
legally permitted (by Delaware law, this Certificate of Incorporation, its
By-laws, contractual provisions or otherwise) to pay the Redemption Price of any
shares of Series D Preferred Stock required to be redeemed by the Corporation on
such Redemption Date, the Corporation shall promptly take all action (including,
without limitation, a revaluation of assets or a prepayment of indebtedness
restricting such redemption) as may be permitted by applicable law to permit
such redemption in full. If the Corporation remains unable after the taking of
such action to repurchase any or all of such shares, the Corporation shall
immediately repurchase such shares upon the termination of such legal
prohibition.

          (e) The price (as used in this Article VIII, the "Redemption Price")
at which each share of Series D Preferred Stock is to be redeemed by the
Corporation pursuant to this Section 4 shall be equal to the greater of (i) the
Liquidation Amount of such share on the date of such redemption and (ii) the
Fair Market Value of such share on the date of redemption. The conversion of any
shares of the Series D Preferred Stock into Common Stock shall have no effect on
the Redemption Price payable in connection with the redemption of the shares of
Series D Preferred Stock not so converted.

          (f) Any communication or notice relating to redemption given pursuant
to this Section 4 shall be sent by first-class certified mail, return receipt
requested, postage prepaid, to the holders of record of shares of Series D
Preferred Stock, at their respective addresses as the same shall appear on the
books of the Corporation, or to the Corporation at the address of its principal,
or registered office, as the case may be. At any time on or after the Redemption
Date,

                                      -44-



the holders of record of shares of Series D Preferred Stock being redeemed in
accordance with this Section 4 shall be entitled to receive the Redemption Price
as determined upon actual delivery to the Corporation or its agents of the
certificates representing the shares to be redeemed.

          Section 5. Voting Rights.

          (a) In addition to the rights provided by law or in the Corporation's
By-laws, each share of Series D Preferred Stock shall entitle the holder thereof
to such number of votes as shall equal the number of shares of Common Stock into
which such share of Series D Preferred Stock is then convertible pursuant to
Section 6 at the record date for the determination of stockholders entitled to
vote or, if no record date is established, at the date such vote is taken. In
addition to class or series voting rights provided by law or in this Certificate
of Incorporation, the holders of Series D Preferred Stock shall be entitled to
vote on all matters as to which holders of Common Stock shall be entitled to
vote in the same manner and with the same effect as such holders of Common
Stock, voting together with the holders of Common Stock, the holders of the
Series A Preferred Stock (calculated on an as-converted basis ) and the holders
of other Priority Preferred Stock (calculated on an as-converted basis) as one
class.

          (b) For so long as at least 25% of the shares of Series D Preferred
Stock ever issued by the Corporation remain outstanding, in addition to the
other rights specified in this Section 5, the holders of a majority of the
shares of Series D Preferred Stock outstanding, voting separately as one class,
shall have the special and exclusive right to elect to the Board one director,
who shall be an individual knowledgable regarding the industry and markets in
which the Corporation operates. In any election of directors by the holders of
Series D Preferred Stock pursuant to this Section 5(b), each holder of Series D
Preferred Stock shall be entitled to one vote for each share of Series D
Preferred Stock held. The Corporation shall take all actions necessary to
effectuate the terms and provisions of this Section 5(b). The special and
exclusive voting rights of the holders of Series D Preferred Stock contained in
this Section 5(b) may be exercised either at a special meeting of the holders of
Series D Preferred Stock called as provided below, or at any annual or special
meeting of the stockholders of the Corporation, or by written consent of such
holders in lieu of a meeting. The director to be elected pursuant to this
Section 5(b) shall serve for terms extending from the date of his or her
election and qualification until his or her successors shall have been elected
and qualified. If at any time the directorship to be filled by the holders of
Series D Preferred Stock pursuant to this Section 5(b) has been vacant for a
period of 10 days, the Secretary of the Corporation shall, upon the written
request of any holder of Series D Preferred Stock, call a special meeting of the
holders of Series D Preferred Stock for the purpose of electing a director to
fill such vacancy. Such meeting shall be held at the earliest practicable date,
and at such place, as is specified in or determined in accordance with the
By-laws of the Corporation. If such meeting shall not be called by the Secretary
of the Corporation within 10 days after personal service of such written request
on the Secretary of the Corporation, then any holder of Series D Preferred Stock
may designate in writing any holder of Series D Preferred Stock to call such
meeting at the expense of the Corporation, and such meeting may be called by
such person so designated upon the notice required for annual meetings of
stockholders and shall be held at such place as specified in such notice. Any
holder of Series D Preferred Stock so designated shall have access to the stock
books of the Corporation relating to Series D Preferred Stock for the purpose of
calling a meeting of the stockholders pursuant to these

                                      -45-



provisions. At any meeting held for the purpose of electing the director as
provided in this Section 5(b), the presence, in person or by proxy, of the
holders of record of shares representing at least a majority of the shares of
the Series D Preferred Stock then outstanding shall be required to constitute a
quorum of the Series D Preferred Stock for such election. The vacancy in the
directorship to be elected by the holders of Series D Preferred Stock pursuant
to this Section 5(b) may be filled only by vote or written consent in lieu of a
meeting of the holders of at least a majority of the voting power of the Series
D Preferred Stock.

          (c) The Corporation shall not, without the affirmative consent or
approval of the holders of a majority of the shares of the Series D Preferred
Stock then outstanding, voting together as a class, amend the Certificate of
Incorporation of the Corporation in any way that adversely affects the
conversion terms of the Series D Preferred Stock.

          Section 6. Conversion.

          (a) Upon the terms set forth in this Section 6, by surrender of the
certificate representing each share, each holder of each share of Series D
Preferred Stock shall have the right, at such holder's option, at any time and
from time to time, to convert all or any part of such shares into the number of
fully paid and nonassessable shares of Common Stock equal to the quotient
obtained by dividing (A) the Liquidation Amount of such share on the date of
such conversion by (B) the Conversion Price (as defined below), as last adjusted
and then in effect. The conversion price per share at which shares of Common
Stock shall be issuable upon conversion of shares of Series D Preferred Stock
shall be the quotient obtained by dividing (x) the Pre-Money Valuation by (y)
the number of shares of Common Stock of the Corporation outstanding or issuable
upon conversion, exercise or exchange of any outstanding securities (other than
Bridge Notes), in each case immediately prior to the first date of issuance of
any shares of Series D Preferred Stock, as adjusted pursuant to paragraph (e)
below, (the "Conversion Price"). The holder of any shares of Series D Preferred
Stock may exercise the conversion right pursuant to this paragraph (a) by
delivering to the Corporation the certificate for the shares to be converted,
duly endorsed or assigned in blank or to the Corporation (if required by it),
accompanied by written notice stating that the holder elects to convert such
shares and stating the name or names (with address) in which the certificate or
certificates for the shares of Common Stock are to be issued. Conversion shall
be deemed to have been effected on the date when such delivery is made or upon
the consummation of a Qualified Public Offering as provided below, if applicable
(as used in this Article VIII, the "Conversion Date").

          (b) Upon the terms set forth in this Section 6 upon the consummation
of a Qualified Public Offering or upon the election of the holders of at least
two-thirds of the shares of Series D Preferred Stock then outstanding, voting
together as a class, each share of Series D Preferred Stock shall automatically
be converted into that number of fully paid and nonassessable shares of Common
Stock equal to the quotient obtained by dividing (A) the Liquidation Amount of
such share on the earlier of (i) the date of such conversion and (ii) the date,
if any, which is selected by the Board so that any dividends accruing on the
Series D Preferred Stock after such date and prior to a Qualified Public
Offering shall be paid in cash following the Qualified Public Offering to the
holders of record immediately prior to such Qualified Public Offering, by (B)
the applicable Conversion Price, as last adjusted and then in effect.

                                      -46-



          (c) As promptly as practicable after the conversion of any shares of
Series D Preferred Stock into Common Stock under paragraph (a) or (b) above, the
Corporation shall issue and deliver to or upon the written order of such holder,
to the place designated by such holder, a certificate or certificates for the
number of full shares of Common Stock to which such holder is entitled, and a
cash amount in respect of any fractional interest in a share of Common Stock as
provided in paragraph (d) below. The Person in whose name the certificate or
certificates for Common Stock are to be issued shall be deemed to have become a
stockholder of record on the applicable Conversion Date unless the transfer
books of the Corporation are closed on that date, in which event such Person
shall be deemed to have become a stockholder of record on the next succeeding
date on which the transfer books are open, but the Conversion Price shall be
that in effect on the Conversion Date, and the rights of the holder of the
shares of Series D Preferred Stock so converted shall cease on such Conversion
Date. Upon conversion of only a portion of the number of shares covered by a
certificate representing shares of Series D Preferred Stock surrendered for
conversion, the Corporation shall issue and deliver to or upon the written order
of the holder of the certificate so surrendered for conversion, at the expense
of the Corporation, a new certificate covering the number of shares of Series D
Preferred Stock representing the unconverted portion of the certificate so
surrendered.

          (d) No fractional shares of Common Stock or scrip shall be issued upon
conversion of shares of Series D Preferred Stock. The number of full shares of
Common Stock issuable upon conversion of Series D Preferred Stock shall be
computed on the basis of the aggregate number of shares of such preferred stock
to be converted. Instead of any fractional shares of Common Stock which would
otherwise be issuable upon conversion of any such shares, the Corporation shall
pay a cash adjustment in respect of such fractional interest in an amount equal
to the product of (A) the price of one share of Common Stock as determined in
good faith by the Board and (B) such fractional interest. The holders of
fractional interests shall not be entitled to any rights as stockholders of the
Corporation in respect of such fractional interests.

          (e) The Conversion Price shall be subject to adjustment from time to
time as follows:

               (1) If the Corporation shall, at any time or from time to time
          after the Original Issuance Date, issue any shares of Common Stock
          other than Excluded Stock without consideration or for a consideration
          per share less than the Conversion Price in effect immediately prior
          to the issuance of such Common Stock, then such Conversion Price, as
          in effect immediately prior to each such issuance, shall forthwith be
          lowered to a price equal to the quotient obtained by dividing:

                    (i) an amount equal to the sum of (x) the total number of
               shares of Common Stock outstanding on a fully-diluted basis
               immediately prior to such issuance, multiplied by the Conversion
               Price in effect immediately prior to such issuance, and (y) the
               consideration received by the Corporation upon such issuance; by

                                      -47-



                    (ii) the total number of shares of Common Stock outstanding
               on a fully-diluted basis immediately after the issuance of such
               Common Stock.

               (2) For the purposes of any adjustment of a Conversion Price
          pursuant to clause (1) above, the following provisions shall be
          applicable:

                    (i) In the case of the issuance of Common Stock for cash in
               a public offering or private placement, the consideration shall
               be deemed to be the amount of cash paid therefor after deducting
               therefrom any discounts, commissions or placement fees payable by
               the Corporation to any underwriter or placement agent in
               connection with the issuance and sale thereof.

                    (ii) In the case of the issuance of Common Stock for a
               consideration in whole or in part other than cash, the
               consideration other than cash shall be deemed to be the fair
               market value thereof as determined in good faith by the Board,
               irrespective of any accounting treatment.

                    (iii) In the case of the issuance of options to purchase or
               rights to subscribe for Common Stock, securities by their terms
               convertible into or exchangeable for Common Stock, or options to
               purchase or rights to subscribe for such convertible or
               exchangeable securities except for options to acquire Excluded
               Stock:

                         (A) the aggregate maximum number of shares of Common
                    Stock deliverable upon exercise of such options to purchase
                    or rights to subscribe for Common Stock shall be deemed to
                    have been issued at the time such options or rights were
                    issued and for a consideration equal to the consideration
                    (determined in the manner provided in subdivisions (e)(2)(i)
                    and (e)(2)(ii) above), if any, received by the Corporation
                    upon the issuance of such options or rights plus the minimum
                    purchase price provided in such options or rights for the
                    Common Stock covered thereby;

                         (B) 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 to purchase or rights to subscribe for
                    such convertible or exchangeable securities and subsequent
                    conversion or exchange thereof shall be deemed to have been
                    issued at the time such securities, options, or rights were
                    issued and for a consideration equal to the consideration
                    received by the Corporation for any such securities and
                    related options or rights (excluding any cash received on
                    account of accrued interest or

                                      -48-



                    accrued dividends), plus the additional consideration, if
                    any, to be received by the Corporation upon the conversion
                    or exchange of such securities or the exercise of any
                    related options or rights (the consideration in each case to
                    be determined in the manner provided in subdivisions
                    (e)(2)(i) and (e)(2)(ii) above);

                         (C) on any change in the number of shares or exercise
                    price of Common Stock deliverable upon exercise of any such
                    options or rights or conversions of or exchanges for such
                    securities, other than a change resulting from the
                    antidilution provisions thereof, the Conversion Price shall
                    forthwith be readjusted to such Conversion Price as would
                    have been obtained had the adjustment made upon the issuance
                    of such options, rights or securities not converted prior to
                    such change, or options or rights related to such securities
                    not converted prior to such change, been made upon the basis
                    of such change;

                         (D) on the expiration of any such options or rights,
                    the termination of any such rights to convert or exchange or
                    the expiration of any options or rights related to such
                    convertible or exchangeable securities, the Conversion Price
                    shall forthwith be readjusted to such Conversion Price as
                    would have been obtained had the adjustment made upon the
                    issuance of such options, rights, securities or options or
                    rights related to such securities been made upon the basis
                    of the issuance of only the number of shares of Common Stock
                    actually issued upon the exercise of such options or rights,
                    upon the conversion or exchange of such securities, or upon
                    the exercise of the options or rights related to such
                    securities and subsequent conversion or exchange thereof;
                    and

                         (E) no further adjustment of the Conversion Price
                    adjusted upon the issuance of any such options, rights,
                    convertible securities or exchangeable securities shall be
                    made as a result of the actual issuance of Common Stock on
                    the exercise of any such rights or options or any conversion
                    or exchange of any such securities.

               (3) If, at any time after the Original Issuance Date, the number
          of shares of Common Stock outstanding is increased by a stock dividend
          payable in shares of Common Stock or by a subdivision or split-up of
          shares of Common Stock, then, following the record date for the
          determination of holders of Common Stock entitled to receive such
          stock dividend, subdivision or split-up, the Conversion Price shall be
          appropriately decreased so that the number of shares of Common Stock
          issuable on conversion of each share of Series D Preferred Stock shall
          be increased in proportion to such increase in outstanding shares.

                                      -49-



               (4) If, at any time after the Original Issuance Date, the number
          of shares of Common Stock outstanding is decreased by a combination of
          the outstanding shares of Common Stock (including, without limitation,
          as contemplated by the reverse stock split referred to in Section 4 of
          Article IV), then, following the record date for such combination, the
          Conversion Price shall be appropriately increased so that the number
          of shares of Common Stock issuable on conversion of each share of
          Series D Preferred Stock shall be decreased in proportion to such
          decrease in outstanding shares.

               (5) In the event of any capital reorganization of the
          Corporation, any reclassification of the stock of the Corporation
          (other than a change in par value or from par value to no par value or
          from no par value to par value or as a result of a stock dividend or
          subdivision, split-up or combination of shares), or any consolidation
          or merger of the Corporation, each share of Series D Preferred Stock
          shall after such reorganization, reclassification, consolidation, or
          merger be convertible into the kind and number of shares of stock or
          other securities or property of the Corporation or of the corporation
          resulting from such consolidation or surviving such merger to which
          the holder of the number of shares of Common Stock deliverable
          (immediately prior to the time of such reorganization,
          reclassification, consolidation or merger) upon conversion of such
          share of Series D Preferred Stock would have been entitled upon such
          reorganization, reclassification, consolidation or merger. The
          provisions of this clause shall similarly apply to successive
          reorganizations, reclassifications, consolidations or mergers.

               (6) No adjustment in any Conversion Price shall be required
          unless such adjustment would require an increase or decrease of at
          least $0.01 in such Conversion Price; provided, that any adjustments
          not required to be made by virtue of this sentence shall be carried
          forward and taken into account in any subsequent adjustment. All
          calculations under paragraphs (1) through (5) above shall be made to
          the nearest one hundredth (1/100) of a cent or the nearest one tenth
          (1/10) of a share, as the case may be.

               (7) In any case in which the provisions of this paragraph (e)
          shall require that an adjustment shall become effective immediately
          after a record date of an event, the Corporation may defer until the
          occurrence of such event (1) issuing to the holder of any share of
          Series D Preferred Stock converted after such record date and before
          the occurrence of such event the shares of capital stock issuable upon
          such conversion by reason of the adjustment required by such event in
          addition to the shares of capital stock

                                      -50-



          issuable upon such conversion before giving effect to such
          adjustments, and (2) paying to such holder any amount in cash in lieu
          of a fractional share of capital stock pursuant to paragraph (d)
          above; provided, however, that the Corporation shall deliver to such
          holder an appropriate instrument evidencing such holder's right to
          receive such additional shares and such cash.

               (8) Whenever a Conversion Price shall be adjusted as provided in
          paragraph (4), the Corporation shall make available for inspection
          during regular business hours, at its principal executive offices or
          at such other place as may be designated by the Corporation, a
          statement, signed by its chief executive officer, showing in detail
          the facts requiring such adjustment and the Conversion Price that
          shall be in effect after such adjustment. The Corporation shall also
          cause a copy of such statement to be sent by first class certified
          mail, return receipt requested and postage prepaid, to each holder of
          Series D Preferred Stock at such holder's address appearing on the
          Corporation's records. Where appropriate, such copy may be given in
          advance and may be included as part of any notice required to be
          mailed under the provisions of paragraph (9) below.

               (9) If the Corporation shall propose to take any action of the
          types described in clauses (3), (4) or (5) of this paragraph (e), the
          Corporation shall give notice to each holder of shares of Series D
          Preferred Stock, in the manner set forth in paragraph (8) above, which
          notice shall specify the record date, if any, with respect to any such
          action and the date on which such action is to take place. Such notice
          shall also set forth such facts with respect thereto as shall be
          reasonably necessary to indicate the effect of such action (to the
          extent such effect may be known at the date of such notice) on the
          Conversion Price and the number, kind or class of shares or other
          securities or property which shall be deliverable or purchasable upon
          the occurrence of such action or deliverable upon conversion of shares
          of Series D Preferred Stock. In the case of any action which would
          require the fixing of a record date, such notice shall be given at
          least 20 days prior to the date so fixed, and in case of all other
          action, such notice shall be given at least 30 days prior to the
          taking of such proposed action. Failure to give such notice, or any
          defect therein, shall not affect the legality or validity of any such
          action.

               (10) The Corporation shall at all times keep reserved, free from
          preemptive rights, out of its authorized but unissued shares of Common
          Stock, solely for the purpose of effecting the conversion of the
          Series D Preferred Stock, sufficient shares of Common

                                      -51-



          Stock to provide for the conversion of all outstanding shares of
          Series D Preferred Stock.

               (11) Without duplication of any other adjustment provided for in
          this Section 6, at any time the Corporation makes or fixes a record
          date for the determination of holders of Common Stock entitled to
          receive a dividend or other distribution payable in securities of the
          Corporation other than shares of Common Stock, provision shall be made
          so that each holder of Series D Preferred Stock shall receive upon
          conversion thereof, in addition to the shares of Common Stock
          receivable thereupon, the number of securities of the Corporation
          which it would have received had its shares of Series D Preferred
          Stock been converted into shares of Common Stock on the date of such
          event and had such holder thereafter, during the period from the date
          of such event to and including the date of conversion, retained such
          securities receivable by it pursuant to this paragraph during such
          period, subject to the sum of all other adjustments called for during
          such period under this Section 6 with respect to the rights of such
          holder of Series D Preferred Stock.

          Section 7. Definitions.

     As used in this Article VIII, the following terms shall have the following
meanings:

          (a) "Applicable Dividend Rate" means 6% per annum.

          (b) "Arbitration Procedure", if applicable, means the following
procedure to determine the Fair Market Value (as used in this Article VIII, the
"Valuation Amount"). The Valuation Amount shall be determined by an investment
banking firm of national standing in the United States, which firm shall be
reasonably acceptable to the Corporation and the holders of at least two thirds
of Series D Preferred Stock. If the Corporation and the holders of at least two
thirds of Series D Preferred Stock are unable to agree upon an acceptable
investment banking firm within 10 days after the date either party proposed that
one be selected, the investment banking firm will be selected by an arbitrator
located in the New York City, selected by the American Arbitration Association
in New York City (as used in this Article VIII, the "Association") (or if such
organization ceases to exist, the arbitrator shall be chosen by a court of
competent jurisdiction in New York City). The arbitrator shall select the
investment banking firm (within 10 days of a request therefor from either the
Corporation or the holders of at least two thirds of Series D Preferred Stock)
from a list, jointly prepared by the Corporation and the holders of at least two
thirds of Series D Preferred Stock, of not more than six investment banking
firms of national standing in the United States, of which no more than three may
be named by the Corporation and no more than three may be named by the holders
of at least two thirds of Series D Preferred Stock. The arbitrator may consider,
within the ten-day period allotted, arguments from the parties regarding which
investment banking firm to choose, but the selection by the arbitrator shall be
made in its sole discretion from the list of six. The Corporation and the
holders of at least two thirds of Series D Preferred Stock shall submit to the

                                      -52-



investment banking firm selected by the arbitrator their respective good faith
calculations of the valuation amount, and any supporting arguments and other
data as they may desire, within 30 days of the appointment of the investment
banking firm, and the investment banking firm shall as soon as practicable
thereafter make its own calculation of the valuation amount. The final valuation
amount for purposes hereof shall be the average of the two valuation amounts
closest together, as determined by the investment banking firm, from among the
valuation amounts submitted by the Corporation and the holders of at least two
thirds of Series D Preferred Stock and the valuation amount calculated by the
investment banking firm. The determination of the final valuation amount by such
investment banking firm shall be final and binding upon the parties. The
Corporation shall pay the fees and expenses of the investment banking firm, the
Association and the arbitrator (if any) used to determine the valuation amount.
If required by any such investment banking firm or arbitrator, the Corporation
shall execute a retainer and engagement letter containing reasonable terms and
conditions, including, without limitation, customary provisions concerning the
rights of indemnification and contribution by the Corporation in favor of such
investment banking firm or arbitrator and its officers, directors, partners,
employees, agents and Affiliates.

          (c) "Bridge Notes" means the Senior Convertible Bridge Notes due 2004
of the Company, in an aggregate principal amount of one million dollars.

          (d) "Conversion Date" shall have the meaning ascribed to it in Section

Section 6(b).

          (f) "Excluded Stock" means (1) up to 7,500,000 shares (as adjusted

approved by the Board) granted to directors, officers, employees and consultants
of the Corporation or its subsidiaries pursuant to any equity incentive plan of
the Corporation and (2) shares of Common Stock issued upon conversion of shares
of the Series A Preferred Stock, the Series B Preferred Stock, the Series C
Preferred Stock and the Series D Preferred Stock.

          (g) "Fair Market Value" means, with respect to any share of Common
Stock of the Corporation, the fair value of such share of Common Stock
determined by the mutual agreement of the Corporation and the holders of at
least two-thirds of Series D Preferred Stock. If such parties are unable to
reach agreement as to Fair Market Value within a reasonable period of time (not
to exceed 30 days), Fair Market Value shall be determined pursuant to the
Arbitration Procedure.

          (h) "Liquidation Amount" means as to each share of Series D Preferred
Stock, the Original Cost plus all accrued dividends thereon through the date of
payment of such amount to the holder thereof (as adjusted for stock splits,
stock dividends and the like).

          (i) "Liquidation Preference Payment" shall have the meaning ascribed
to it in Section 3(a).

          (j) "Original Cost" means with respect to each share of Series D
Preferred Stock $1.00 per share (as adjusted for stock splits, stock dividends
and the like).

          (k) "Original Issuance Date" shall be determined with respect to each
share of Series D Preferred Stock separately and shall mean the date that the
Corporation received full payment in cash or conversion of Bridge Notes for such
share of Series D Preferred Stock.

          (l) "Pre-Money Valuation" means, initially, fifteen million dollars

Valuation shall be increased by the amount, if any, of the aggregate proceeds to
the Corporation of any sales of Common Stock or securities convertible into, or
exchangeable for, shares of Common Stock (other than Bridge Notes) occurring
after June 11, 2003 and prior to the first date of issuance of any shares of
Series D Preferred Stock. The Pre-Money Valuation shall also be increased, if
the Corporation shall issue any options to purchase, or rights to subscribe for,
Common Stock (or securities convertible into, or exchangeable for, shares of
Common Stock) (other than Bridge Notes) after June 11, 2003 and prior to the
first date of issuance of any shares of Series D Preferred Stock, by the amount
of the aggregate proceeds to the Corporation from the sale thereof and any
additional amounts payable upon exercise of the purchase rights pursuant
thereto.

          (m) "Qualified Public Offering" means a public offering of securities
of the Corporation underwritten on a firm basis by an underwriter reasonably
satisfactory to the holders of at least a majority of the Priority Preferred

holders of any other shares of any series or class of capital stock with
participation rights (the "Other Participating Securities") and Common Stock

to its stockholders in the same proportion as the number of shares of
outstanding Common Stock issuable upon the conversion of outstanding Series A
Preferred Stock, Series D Preferred Stock, Priority Preferred Stock and Other
Participating Securities then held by each such stockholder bears to the total
number of shares of outstanding Common Stock plus the Common Stock issuable upon
conversion of outstanding Series A Preferred Stock, Series D Preferred Stock,
Priority Preferred Stock and Other Participating Securities.

                                   ARTICLE IX

Whenever a compromise or arrangement is proposed between this Corporation and
its creditors or any class of them and/or between this Corporation and its
stockholders or any class of them, any court of equitable jurisdiction within
the State of Delaware may, on the application in a summary way of this
Corporation or of any creditor or stockholder thereof or on the application of
any receiver or receivers appointed for this Corporation under (S) 291 the DGCL
(or any successor section) or on the application of trustees in dissolution or
of any receiver or receivers appointed for this Corporation under (S) 279 of the
DGCL (or any successor section) order a meeting of the creditors or class of
creditors, and/or of the stockholders or class of stockholders of this
Corporation, as the case may be, to be summoned in such manner as the said court
directs.

                                      -54-



If a majority in number representing three fourths in value of the creditors or
class of creditors, and/or of the stockholders or class of stockholders of this
Corporation, as the case may be, agree to any compromise or arrangement and to
any reorganization of this Corporation as consequence of such compromise or
arrangement, the said compromise or arrangement and the said reorganization
shall, if sanctioned by the court to which the said application has been made,
be binding on all the creditors or class of creditors, and/or on all the
stockholders or class of stockholders, of this Corporation, as the case may be,
and also on this Corporation.

                                    ARTICLE X

The Board of this Corporation shall have the power to adopt, amend or repeal
By-laws of this Corporation, subject to the power of the stockholders of this
Corporation to adopt By-laws and to amend or repeal By-laws adopted by the
Board.

                                   ARTICLE XI

     For the management of the business and for the conduct of the affairs of
the Corporation, and in further definition, limitation, and regulation of the
powers of the Corporation and of its directors and of its stockholders or any
class thereof, as the case may be, it is further provided:

          Section 1. The management of the business and the conduct of the
affairs of the Corporation shall be vested in its Board of Directors. The number
of directors which shall constitute the whole Board of Directors shall be fixed
by, or in the manner provided in, the By-laws. The phrase "whole Board" and the
phrase "total number of directors" shall be deemed to have the same meaning, to
wit, the total number of directors which the Corporation would have if there
were no vacancies. No election of directors need be by written ballot.

          Section 2. From and after the consummation of a Qualified Public
Offering, the Board shall be divided into three classes, as nearly equal in
number as the then total number of directors constituting the entire Board
permits, with the term of office of one or another of the three classes expiring
each year. The Board shall by resolution initially divide the Board into three
classes, with the term of office of the first class to expire at the Annual
Meeting of Stockholders to be held during 2005, the term of office of the second
class to expire at the Annual Meeting of Stockholders to be held during 2006 and
the term of office of the third class to expire at the Annual Meeting of
Stockholders to be held during 2007.

          Section 3. Commencing with the first Annual Meeting of Stockholders
following a Qualified Public Offering, the directors elected at an annual
meeting of stockholders to succeed those whose terms then expire shall be
identified as being directors of the same class as the directors whom they
succeed, and each of them shall hold office until the third succeeding annual
meeting of stockholders and until such director's successor is elected and has
been qualified. Any vacancies in the Board for any reason, and any created
directorships resulting from any increase in the number of directors, may be
filled by the vote of not less than a majority of the members of the Board then
in office, although less than a quorum, and any directors so chosen shall hold
office until the next election of the class for which such directors shall have
been chosen and until their successors shall be elected and qualified.
Notwithstanding the foregoing, and except as otherwise required by law, whenever
the holders of any one or more

                                      -55-



series of preferred stock shall have the right, voting separately as a class, to
elect one or more directors of the Corporation, the then authorized number of
directors shall be increased by the number of directors so to be elected, and
the terms of the director or directors elected by such holders shall expire at
the next succeeding annual meeting of stockholders.

          Section 4. From and after the consummation of a Qualified Public
Offering, notwithstanding any other provisions of this Certificate of
Incorporation or the By-laws of the Corporation, any director or the entire
Board of the Corporation may be removed at any time, but only for cause and only
by the affirmative vote of the holders of a majority of the outstanding shares
of capital stock of the Corporation entitled to vote generally in the election
of directors (considered for this purpose as one class, with preferred stock,
the terms of which provide for voting as to such matters, voting on an
as-converted basis, unless otherwise provided in the amendment to this
Certificate of Incorporation defining the rights of the holders of such
preferred stock) cast at a meeting of the stockholders called for that purpose.
Notwithstanding the foregoing, and except as otherwise required by law, whenever
the holders of any one or more series of preferred stock shall have the right,
voting separately as a class, to elect one or more directors of the Corporation,
the provisions of this Section 4 shall not apply with respect to the election of
the director or directors elected by such holders of preferred stock.

          Section 5. From and after the consummation of a Qualified Public
Offering, notwithstanding any other provisions of this Certificate of
Incorporation or the By-laws of the Corporation, any action by the Corporation's
stockholders may only be effected at an annual or special meeting of the
Corporation's stockholders called in compliance with Section 6 below, or
pursuant to an unanimous written consent of the Corporation's stockholders in
compliance with (S)228 of the DGCL (or any successor section of the DGCL).

          Section 6. Special meetings of the stockholders may be called
exclusively by the Board, the Chairman of the Board, the Corporation's President
or any Vice President or the Secretary, upon not less than 10 days written
notice to the stockholders. Such notice shall state the purpose or purposes of
the proposed special meeting. The business transacted at any special meeting
shall be limited to the purposes stated when the meeting is called or in the
notice of such meeting.

          Section 7. Notwithstanding any other provisions of this Certificate of
Incorporation or the By-laws of the Corporation (and notwithstanding the fact
that some lesser percentage may be specified by law, this Certificate of
Incorporation or the By-laws of the Corporation), the affirmative vote of the
holders of 80% or more of the voting power represented by the outstanding shares
of capital stock of the Corporation entitled to vote generally in the election
of directors (considered for this purpose as one class) shall be required to
amend, alter, change or repeal this Article XI or any portion hereof.

                                   ARTICLE XII

     The personal liability of the directors of the Corporation is hereby
eliminated to the fullest extent permitted by the provisions of paragraph (7) of
subsection (b) of (S) 102 of the DGCL, (or any successor section of the DGCL).

                                      -56-



                                  ARTICLE XIII

     The Corporation shall, to the fullest extent permitted by the provisions of
(S) 145 of the DGCL, (or any successor section of the DGCL), indemnify any and
all persons whom it shall have power to indemnify under said section from and
against any and all of the expenses, liabilities, or other matters referred to
in or covered by said section, and the indemnification provided for herein shall
not be deemed exclusive of any other rights to which those indemnified may be
entitled under any By-law, agreement, vote of stockholders or disinterested
directors or otherwise, both as to action in his official capacity and as to
action in another capacity while holding such office, and shall continue as to a
person who has ceased to be a director, officer, employee, or agent and shall
inure to the benefit of the heirs, executors, and administrators of such a
person.

                                   ARTICLE XIV

     Except as may be otherwise provided in this Certificate of Incorporation,
from time to time any of the provisions of this Certificate of Incorporation may
be amended, altered, or repealed, and other provisions authorized by the laws of
the State of Delaware at the time in force may be added or inserted in the
manner and at the time prescribed by said laws, and all rights at any time
conferred upon the stockholders of the Corporation by this Certificate of
Incorporation are granted subject to the provisions of this Article

                                   ARTICLE XV

     The foregoing amendment and restatement was approved by the holders of the
requisite number of shares of said Corporation in accordance with (S) 228 of the
DGCL.

                                   ARTICLE XVI

     That said amendment and restatement was duly adopted in accordance with the
provisions of (S)(S) 242 and 245 of the DGCL.

                                      -57-
