                                    ANNEX A

                     SERIES A CONVERTIBLE PREFERRED STOCK

          The powers, designations, preferences and relative, participating,
optional or other rights of the Series A Convertible Preferred Stock of IFX
Corporation (the "Corporation") are as follows:

     1.   DESIGNATION AND AMOUNT.

          This series of preferred stock shall be designated as "Series A
Convertible Preferred Stock" and shall be divided into two classes:  Class I
Series A Convertible Preferred Stock ("Class I Preferred") and Class II Series A
Convertible Preferred Stock ("Class II Preferred," and together with the Class I
Preferred, the "Series A Convertible Preferred Stock").  The Series A
Convertible Preferred Stock shall have $1.00 par value per share.  The number of
authorized shares constituting the Class I Preferred shall be 1,210,398 shares.
The number of authorized shares constituting the Class II Preferred shall be
820,471 shares.  Shares of the Class I Preferred have a stated value of Twelve
and 31/100 Dollars ($12.31) per share and pursuant to the Series A Stock
Purchase Agreement (the "Series A Stock Purchase Agreement") dated June 15, 2000
among the Company, UBS Capital Americas III, L.P. and UBS Capital LLC (together
"UBS") the stated value of the shares of the Class II Preferred has been
determined and shall hereinafter be Twelve and 31/100 Dollars ($12.31) (as
applicable to the Class I Preferred or the Class II Preferred, as the case may
be, the "Stated Value").  The Corporation has also authorized 4,418,262 shares
of Series B Convertible Preferred Stock, par value $1.00 per share (the "Series
B Convertible Preferred Stock") having the number, powers, preferences and
relative, participating, optional and other rights as set forth in the
Certificate of Designation filed with the Secretary of State of the State of
Delaware on the date of the filing hereof (the "Series B Certificate").

     2.   DIVIDENDS.

          (a)  Right to Receive Dividends.  Holders of Series A Convertible
Preferred Stock shall be entitled to receive dividends when, as and if declared
by the Board of Directors of the Corporation (the "Board of Directors").

          (b)  Participation with Common Stock.  In the event the Board of
Directors shall elect to pay or declare and set apart for payment any dividend
on any shares of common stock, par value $.02 per share, of the Corporation (the
"Common Stock") in cash out of funds legally available therefor or in stock or
other consideration, the holders of the Series A Convertible Preferred Stock
shall be entitled to receive, before any dividend shall be declared and paid or
set aside for the Common Stock, dividends payable in the form and in an amount
per share equal to the per share amount that would have been payable to such
holders had such holders converted their Series A Convertible Preferred Stock
into Common Stock pursuant to Section 5 below.

          (c)  Dividend Preference.  Dividends on the Series A Convertible
Preferred Stock shall be payable before any dividends or distributions or other
payments shall be paid or set aside for payment upon the Common Stock or any
other stock ranking on liquidation or as to dividends


or distributions junior to the Series A Convertible Preferred Stock (any such
stock, together with the Common Stock, being referred to hereinafter as "Junior
Stock"). If there shall be outstanding shares of any class or series of capital
stock which is entitled to share ratably with the Series A Convertible Preferred
Stock in the payment of dividends or distributions or upon liquidation ("Parity
Securities"), no full dividends shall be declared or paid or set apart for
payment on any such securities unless dividends have been or contemporaneously
are ratably declared and paid or declared and a sum sufficient for the payment
thereof set apart for such payment on the Series A Convertible Preferred Stock.

     3.   LIQUIDATION PREFERENCE.

          (a)  In the event of any bankruptcy, liquidation, dissolution or
winding up of the Corporation, either voluntary or involuntary, each holder of
Series A Convertible Preferred Stock at the time thereof shall be entitled to
receive, prior and in preference to any distribution of any of the assets or
funds of the Corporation to the holders of the Common Stock or other Junior
Stock by reason of their ownership of such stock, an amount per share of Series
A Convertible Preferred Stock equal to the sum of (x) the applicable Stated
Value plus any declared and unpaid dividends to the date of liquidation, plus
(y) 10% of such Stated Value per annum, calculated from the date of issuance of
such share through date of payment of the liquidation preference as set forth in
this Section 3 (the "Liquidation Preference").  After the payment of the full
Liquidation Preference on account of all shares of Series A Convertible
Preferred Stock as set forth in this Section 3 and any preferential amounts to
which the holders of Parity Securities are entitled, the remaining assets of the
Corporation legally available for distribution, if any, shall be distributed
ratably to the holders of the Common Stock.  If the assets and funds legally
available for distribution among the holders of Series A Convertible Preferred
Stock shall be insufficient to permit the payment to the holders of the full
aforesaid preferential amount, then the assets and funds shall be distributed
ratably among holders of Series A Convertible Preferred Stock in proportion to
the number of shares of Series A Convertible Preferred Stock owned by each
holder.  If the assets and funds of the Corporation available for distribution
to stockholders upon any bankruptcy, liquidation, dissolution or winding up of
the affairs of the Corporation, whether voluntary or involuntary, shall be
insufficient to permit the payment to holders of the full aforesaid preferential
amount and amounts payable to holders of outstanding Parity Securities, the
holders of Series A Convertible Preferred Stock and the holders of such other
Parity Securities shall share ratably (and ratably as to cash, in-kind or other
distributions) in any distribution of assets of the Corporation in proportion to
the full respective preferential amounts to which they are entitled.

          (b)  Except as described in the following sentence, a merger,
recapitalization, reorganization, sale of voting control to a single buyer or a
group of related buyers in one or a series of related transactions, or other
business combination transaction involving the Corporation in which the
shareholders of the Corporation immediately prior to the consummation of such
transaction do not own at least a majority of the outstanding shares of the
surviving corporation or the Corporation (as applicable) immediately following
the consummation of such transaction or sale of all or substantially all of the
assets of the Corporation (collectively, a "Liquidation Event") shall be deemed
to be a liquidation of the Corporation.  Notwithstanding the foregoing, the
following shall not be deemed to be a Liquidation Event: (i) a merger,
recapitalization, sale of voting control or other

                                       2


business combination transaction with an Affiliate (as such term is defined in
Section 12b-2 of the Rules and Regulations under the Securities Exchange Act of
1934, as amended) of UBS, or (ii) a merger of the Corporation with a public
company (A) in which the merger consideration to be received by the holders of
the Series A Convertible Preferred Stock is fully registered marketable
securities (the "Merger Shares") which are not subject to any restrictions on
transfer, (B) in which the value of such merger consideration for each share of
Series A Convertible Preferred Stock, valued at the average closing price of the
Merger Shares for the 30 days prior to the consummation of the merger, or such
lesser period which follows the public announcement of the merger, is greater
than 110% of the Liquidation Preference per share as of the date of consummation
of the merger, and (C) with aggregate trading volume for the 30 calendar days
prior to the merger date of at least 10 times the aggregate number of Merger
Shares received by all holders of Series A Convertible Preferred Stock.

          (c)  In any Liquidation Event, if the consideration received by the
Corporation is other than cash, its value will be deemed its fair market value
as determined in good faith by the Board of Directors.  Any securities shall be
valued as follows:

               (i)   Securities not subject to investment letter or other
similar restrictions on free marketability covered by subsection (ii) below:

                     (A) If traded on a securities exchange or through The
     Nasdaq National Market or Small Cap Market, the value shall be deemed to be
     the average of the closing prices of the securities on such quotation
     system over the thirty (30) day period ending three (3) days prior to the
     closing of the Liquidation Event;

                     (B) If actively traded over-the-counter, the value shall be
     deemed to be the average of the closing bid or sale prices (whichever is
     applicable) over the thirty (30) day period ending three (3) days prior to
     the closing of the Liquidation Event; and

                     (C) If there is no active public market, the value shall be
     the fair market value thereof, as mutually determined by the Board of
     Directors and the holders of at least a majority of the voting power of all
     then outstanding shares of Series A Convertible Preferred Stock.

               (ii)  The method of valuation of securities subject to investment
letter or other restrictions on free marketability (other than restrictions
arising solely by virtue of a shareholder's status as an affiliate or former
affiliate) shall be to make an appropriate discount from the market value
determined as above in subsections (i)(A), (B) or (C) to reflect the approximate
fair market value thereof, as mutually determined by the Board of Directors and
the holders of at least a majority of the voting power of all then outstanding
shares of Series A Convertible Preferred Stock.

                                       3


     4.   VOTING RIGHTS.

Common Stock or any other capital stock of the Corporation), with each holder of
a share of Series A Convertible Preferred Stock entitled to one vote per share
held by such holder.

               (ii)   Any director elected by the holders of shares of  Series A
Convertible Preferred Stock shall be referred to herein as a "Series A Preferred

appointed pursuant to Section 4(a)(i) will commence upon his/her election by the
Series A Convertible Preferred Stock and shall expire at the first annual
meeting of stockholders of the Corporation following his/her election.  Upon
expiration of the initial term of such Series A Preferred Director, so long as
the Series A Convertible Preferred Stock is outstanding, the holders of the
Series A Convertible Preferred Stock shall have the right to elect a Series A
Preferred Director to replace such director in the same manner described above
in Section 4(a)(i).  Subject to Section 4(a)(v), a Series A Preferred Director
so elected shall hold office for a term expiring at the annual meeting of
stockholders in the year following the election of such director.
Notwithstanding the foregoing, but subject to Section 4(a)(v), a Series A
Preferred Director elected under Section 4(a)(i) shall serve until such Series A
Preferred Director's successor is duly elected and qualified or until such
director's earlier removal as provided in Section 4(a)(iii) or death or
resignation and, in the event a vacancy occurs, a replacement Series A Preferred
Director shall be selected as provided in Section 4(a)(i).

               (iii)  A Series A Preferred Director may be removed by, and shall
not be removed except by, the vote of the holders of record of a majority of the
outstanding shares of Series A Convertible Preferred Stock, voting together as a
single class.

               (iv)   The Corporation shall at all times reserve and keep
available two vacant seats on the Board of Directors solely for the purpose of
enabling the holders of the Series A Convertible Preferred Stock to designate a
Series A Preferred Director as provided in this Section 4(a).

               (v)    This Section 4(a) shall survive a Qualified Public

the aggregate less than 25% of their initial holdings of Series A Shares
determined after the Subsequent Closing (as defined in the Series A Stock

          Shares of Series A Convertible Preferred Stock may be converted into

          (a)  Optional Conversion. (i) At any time and from time to time, each
holder of shares of Series A Convertible Preferred Stock may, upon 30 days'
notice to the Corporation, convert all or any portion of such shares held by
such holder into the number of shares of Common Stock determined by dividing (x)
the applicable Stated Value multiplied by the number of shares surrendered for

Conversion Price on the date of conversion determined in accordance with Section
5(c).

               (ii)  References in this Section 5 to "Common Stock" shall
include all stock or other securities or property (including cash) into which
Common Stock is converted following any merger, reorganization or
reclassification of the capital stock of the Corporation.

          (b)  Mandatory Conversion. Each share of Series A Convertible
Preferred Stock shall automatically be converted into such number of shares of
Common Stock as is determined by dividing (x) the applicable Stated Value
multiplied by the number of shares surrendered for conversion plus any declared
but unpaid dividends on such shares, by (y) the Conversion Price on the date of
conversion determined in accordance with Section 5(c), without 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, upon the
closing of an underwritten public offering of shares of Common Stock for which
the Corporation has obtained a firm commitment from one or more underwriter(s)
for at least $60 million of Common Stock and in which the Corporation receives
gross proceeds from the sale of Common Stock to the public of at least $45
million (before deduction of underwriter's discounts and commissions), and which
values the equity of the Corporation at no less than $200 million pre-offering
(a "Qualified Public Offering"). Except for the purposes of the calculation in
the immediately preceding sentence, in the event of a Qualified Public Offering,
the person(s) entitled to receive the Common Stock issuable upon conversion of
Series A Convertible Preferred Stock shall not be deemed to have converted such
Series A Convertible Preferred Stock until the closing of such offering.

          (c)  Conversion Price.  The Conversion Price per share for the Class I

subject to adjustment as provided in Section 6 hereof.

                                       8


          (d)  Common Stock.  The Common Stock to be issued upon conversion
hereunder shall be fully paid and nonassessable.

          (e)  Procedures for Conversion.

               (i)   In order to convert shares of Series A Convertible
Preferred Stock into shares of Common Stock pursuant to Section 5(a) (or, in the
case of an automatic conversion pursuant to Section 5(b), to receive a
certificate for such holder's shares of Common Stock outstanding as a result of
such conversion), the holder shall surrender the certificate or certificates
therefore, duly endorsed for transfer, at any time during normal business hours,
to the Corporation at its principal or at such other office or agency then
maintained by it for such purpose (the "Payment Office"), accompanied, in the
case of a conversion pursuant to Section 5(a), by written notice to the
Corporation of such holder's election to convert and (if so required by the
Corporation or any conversion agent) by an instrument of transfer, in form
reasonably satisfactory to the Corporation and to any conversion agent, duly
executed by the registered holder or by his duly authorized attorney, and any
taxes required pursuant to Section 5(e)(iii). As promptly as practicable after
the surrender for conversion of any share of Series A Convertible Preferred
Stock in the manner provided in the preceding sentence, and the payment in cash
of any amount required by the provisions of Section 5(e)(iii), but in any event
within five Trading Days of such surrender for payment, the Corporation will
deliver or cause to be delivered at the Payment Office to or upon the written
order of the holder of such shares, certificates representing the number of full
shares of Common Stock issuable upon such conversion, issued in such name or
names as such holder may direct. Such conversion shall be deemed to have been
made immediately prior to the close of business on the date of such surrender of
the shares in proper order for conversion, and all rights of the holder of such
shares as a holder of such shares shall cease at such time and the person or
persons in whose name or names the certificates for such shares of Common Stock
are to be issued shall be treated for all purposes as having become the record
holder or holders thereof at such time; provided, however, that any such
surrender and payment on any date when the stock transfer books of the
Corporation shall be closed shall constitute the person or persons in whose name
or names the certificates for such shares of Common Stock are to be issued as
the record holder or holders thereof for all purposes immediately prior to the
close of business on the next succeeding day on which such stock transfer books
are opened and such conversion shall be at the Conversion Price in effect at
such time on such succeeding day.

          For purposes hereof, "Trading Day" shall mean (i) any day on which
stock is traded on the principal stock exchange on which the Common Stock is
listed or admitted to trading, (ii) if the Common Stock is not then listed or
admitted to trading on any stock exchange but is traded on the Nasdaq Stock
Market, any day on which stock is traded on the Nasdaq Stock Market, or (iii) if
the Common Stock is not then traded on the Nasdaq Stock Market, any day on which
stock is traded in the over-the-counter market, as reported by the National
Quotation Bureau Incorporated (or any similar organization or agency succeeding
to its functions of reporting prices).

               (ii)  The Corporation shall not be required to issue fractional
shares of Common Stock upon conversion of shares of Series A Convertible
Preferred Stock.  At the Corporation's discretion, in the event the Corporation
determines not to issue fractional shares, in

                                       9


lieu of any fractional shares to which the holder would otherwise be entitled,
the Corporation shall pay cash equal to such fraction multiplied by the closing
price of the Common Stock on the date of conversion.

               (iii) The issuance of certificates for shares of Common Stock
upon conversion shall be made without charge for any issue, stamp or other
similar tax in respect of such issuance. However, if any such certificate is to
be issued in a name other than that of the holder of record of the shares
converted, the person or persons requesting the issuance thereof shall pay to
the Corporation the amount of any tax which may be payable in respect of any
transfer involved in such issuance or shall establish to the satisfaction of the
Corporation that such tax has been paid or is not payable.

          (f)  Reservation of Stock Issuable Upon Conversion. Subject to the
limitation set forth in the last sentence of this Section 5(f), the Corporation
shall 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 Convertible Preferred Stock, 7,142,857 shares of Common Stock.
If at any time the number of authorized but unissued shares of Common Stock
shall not be sufficient to effect the conversion of all then outstanding shares
of the Series A Convertible Preferred Stock without regard to whether the
holders of Series A Convertible Preferred Stock are then entitled to convert,
the Corporation will take such corporate action as may, in the opinion of its
counsel, be necessary to increase its authorized but unissued shares of Common
Stock to such number of shares as shall be sufficient for such purpose,
including, without limitation, taking appropriate board action, recommending
such an increase to the holders of Common Stock, holding shareholders meetings,
soliciting votes and proxies in favor of such increase to obtain the requisite
stockholder approval and upon such approval, the Corporation shall reserve and
keep available such additional shares solely for the purpose of effecting the
conversion of the shares of the Series A Convertible Preferred Stock.

          (g)  Merger, Etc.

               (i)   Notwithstanding any other provision hereof, in case of any
merger or other business combination transaction involving the Corporation which
does not constitute a Liquidation Event, then, concurrently with the
consummation of such transaction, provision shall be made so that each share of
Series A Convertible Preferred Stock shall thereafter be convertible into the
number of shares of stock or other securities or property (including cash) to
which a holder of the number of shares of Common Stock deliverable upon
conversion of such share of Series A Convertible Preferred Stock would have been
entitled assuming conversion immediately prior to the closing of the
transaction.

               (ii)  In case of any merger or other business combination
transaction involving the Corporation which does not constitute a Liquidation
Event, in which the Corporation is not the surviving entity, and the Corporation
or the holders do not otherwise convert all outstanding shares of Series A
Convertible Preferred Stock, the Series A Convertible Preferred Stock shall be
converted into or exchanged for and shall become shares of the surviving
corporation having, in respect of the surviving corporation, substantially the
same powers, preferences and relative participating, optional or other special
rights, and the qualifications, limitations or

                                      10


restrictions thereon, that the Series A Convertible Preferred Stock had
immediately prior to such transaction.

               (ii)   In the event that following the consummation of a
Qualified Private Offering, the Corporation shall issue or sell any Additional

Additional Share of Common Stock less than the applicable Conversion Price, then
the applicable Conversion Price shall be reduced to a price determined by
dividing (A) an amount equal to the sum of (x) the number of Fully Diluted
Outstanding shares of Common Stock immediately prior to such issue or sale
multiplied by the then existing Conversion Price plus (y) the aggregate
consideration, if any, received by the Corporation upon such issue or sale, by
(B) the total number of Fully Diluted Outstanding shares of Common Stock
outstanding immediately after such issue or sale.

               (iii)  The provisions of this Section 6(c) shall not apply to any
issuance of Additional Shares of Common Stock for which an adjustment is
provided under Section 6(b).  No adjustment shall be made under this Section
6(c) upon the issuance of any Additional Shares of Common Stock which are issued
pursuant to the exercise of any warrants or other subscription or purchase
rights or pursuant to the exercise of any conversion or exchange rights in any
Convertible Securities, if any such adjustment shall previously have been made
upon the issuance of such warrants or other rights or upon the issuance of such
Convertible Securities (or upon the issuance of any warrant or other rights
therefor) pursuant to Section 6(d) or Section 6(e).

          (d)  Issuance of Warrants or Other Rights.  Except with respect to
Permitted Issuances, if at any time the Corporation shall take a record of the
holders of its Common Stock for the purpose of entitling them to receive a
distribution of, or shall in any manner (whether directly or by assumption in a
merger in which the Corporation is the surviving corporation) issue or sell, any
warrants or other rights to subscribe for or purchase any Additional Shares of
Common Stock or any Convertible Securities, whether or not the rights to
exchange or convert thereunder are immediately exercisable, and the price per
share for which Common Stock is issuable upon the exercise of such warrants or
other rights or upon conversion or exchange of such Convertible Securities shall
be less than the applicable Conversion Price in effect immediately prior to the
time of such distribution, issue or sale, then the applicable Conversion Price
shall be adjusted as provided in Section 6(c)(i) or (ii), as applicable, on the
basis that (i) the maximum number of Additional Shares of Common Stock issuable
pursuant to all such warrants or other rights or necessary to effect the
conversion or exchange of all such Convertible Securities shall be deemed to
have been issued and outstanding, (ii) the price per share for such Additional
Shares of Common Stock shall be deemed to be the lowest price per share at which
such Additional Shares of Common Stock are issuable to such

                                      13


holders, and (iii) the Corporation shall have received all of the consideration,
if any, payable for such warrants or other rights as of the date of the actual
issuance thereof. No further adjustments of the Conversion Price shall be made
upon the actual issue of such Common Stock or of such Convertible Securities
upon exercise of such warrants or other rights or upon the actual issue of such
Common Stock upon such conversion or exchange of such Convertible Securities.

          (e)  Issuance of Convertible Securities.  Except with respect to
Permitted Issuances, if at any time the Corporation shall take a record of the
holders of its Common Stock for the purpose of entitling them to receive a
distribution of, or shall in any manner (whether directly or by assumption in a
merger in which the Corporation is the surviving corporation) issue or sell, any
Convertible Securities, whether or not the rights to exchange or convert
thereunder are immediately exercisable, and the price per share for which Common
Stock is issuable upon such conversion or exchange shall be less than the
applicable Conversion Price in effect immediately prior to the time of such
issue or sale, then the applicable Conversion Price shall be adjusted as
provided in Section 6(c)(i) or (ii), as applicable, on the basis that (i) the
maximum number of Additional Shares of Common Stock issuable upon the conversion
or exchange of all such Convertible Securities shall be deemed to have been
issued and outstanding, (ii) the price per share of such Additional Shares of
Common Stock shall be deemed to be the lowest possible price in any range of
prices at which such Additional Shares of Common Stock are available to such
holders, and (iii) the Corporation shall have received all of the consideration
payable therefor, if any, as of the date of actual issuance of such Convertible
Securities.  No further adjustment of the Conversion Price shall be made under
this Section 6(e) upon the issuance of any Convertible Securities which are
issued pursuant to the exercise of any warrants or other subscription or
purchase rights therefor, if any such adjustment shall previously have been made
upon the issuance of such warrants or other rights pursuant to Section 6(d).  No
further adjustments of the Conversion Price shall be made upon the actual issue
of such Common Stock upon conversion or exchange of such Convertible Securities
and, if any issue or sale of such Convertible Securities is made upon exercise
of any warrant or other right to subscribe for or to purchase or any warrant or
other right to purchase any such Convertible Securities for which adjustments
thereof have been or are to be made pursuant to other provisions of this Section
6, no further adjustments shall be made by reason of such issue or sale.

          (f)  Superseding Adjustment.  If, at any time after any adjustment of
the applicable Conversion Price shall have been made pursuant to Section 6(d) or
6(e) as the result of any issuance of warrants, rights or Convertible
Securities, and either

               (i)    such warrants or rights, or the right of conversion or
          exchange in such other Convertible Securities, shall expire, and all
          or a portion of such warrants or rights, or the right of conversion or
          exchange with respect to all or a portion of such other Convertible
          Securities, as the case may be, shall not have been exercised, or

               (ii)   the consideration per share for which shares of Common
          Stock are issuable pursuant to such warrants or rights, or such other
          Convertible Securities, shall be increased or decreased by virtue of
          provisions therein contained,

                                      14


then such previous adjustment shall be rescinded and annulled and the Additional
Shares of Common Stock which were deemed to have been issued by virtue of the
computation made in connection with the adjustment so rescinded and annulled
shall no longer be deemed to have been issued by virtue of such computation.
Thereupon, a recomputation shall be made of the effect of such rights or options
or other Convertible Securities on the applicable Conversion Price, on the basis
of

               (iii)  treating the number of Additional Shares of Common Stock
          or other property, if any, theretofore actually issued or issuable
          pursuant to the previous exercise of any such warrants or rights or
          any such right of conversion or exchange, as having been issued on the
          date or dates of any such exercise and for the consideration actually
          received and receivable therefor, an d

               (iv)   treating any such warrants or rights or any such other
          Convertible Securities which then remain outstanding as having been
          granted or issued immediately after the time of such increase or
          decrease of the consideration per share for which shares of Common
          Stock or other property are issuable under such warrants or rights or
          other Convertible Securities.

          (g)  Subject Transactions Adjustment.  If the Corporation issues a
number of shares of Common Stock greater than the Share Allowance in connection
with the Subject Transactions, the Conversion Price shall be adjusted to a
dollar amount resulting from the following:

                             $40,464,918
                  ------------------------------------------
                  1.010948(12,919,702 + Overage) - 1,500,000

Notwithstanding the foregoing, an adjustment under this subsection (g) shall
only be made to the extent such adjustment results in a reduction of the then
current Conversion Price.

          (h)  Other Provisions Applicable to Adjustments Under This Section.
The following provisions shall be applicable to the making of adjustments
provided for in this Section 6:

               (i)    Computation of Consideration. To the extent that any
          Additional Shares of Common Stock or any Convertible Securities or any
          warrants or other rights to subscribe for or purchase any Additional
          Shares of Common Stock or any Convertible Securities shall be issued
          for cash consideration, the consideration received by the Corporation
          therefor shall be the amount of the cash received by the Corporation
          therefor, or, if such Additional Shares of Common Stock or Convertible
          Securities are offered by the Corporation for subscription, the
          subscription price, or, if such Additional Shares of Common Stock or
          Convertible Securities are sold to underwriters or dealers for public
          offering without a subscription offering, the public offering price
          (in any such case subtracting any amounts paid or receivable for
          accrued interest or accrued dividends, but not subtracting any
          compensation, discounts or expenses paid or incurred by the
          Corporation for and in the underwriting of, or otherwise in

                                      15


          connection with, the issuance thereof). To the extent that such
          issuance shall be for a consideration other than cash, then, except as
          herein otherwise expressly provided, the amount of such consideration
          shall be deemed to be the fair value of such consideration at the time
          of such issuance as determined in good faith by the Board of
          Directors. In case any Additional Shares of Common Stock or any
          Convertible Securities or any warrants or other rights to subscribe
          for or purchase such Additional Shares of Common Stock or Convertible
          Securities shall be issued in connection with any merger in which the
          Corporation issues any securities, the amount of consideration
          therefor shall be deemed to be the fair value, as determined in good
          faith by the Board of Directors, of such portion of the assets and
          business of the nonsurviving corporation as the Board of Directors in
          good faith shall determine to be attributable to such Additional
          Shares of Common Stock, Convertible Securities, warrants or other
          rights, as the case may be. The consideration for any Additional
          Shares of Common Stock issuable pursuant to any warrants or other
          rights to subscribe for or purchase the same shall be the
          consideration received by the Corporation for issuing such warrants or
          other rights plus the additional consideration payable to the
          Corporation upon exercise of such warrants or other rights. The
          consideration for any Additional Shares of Common Stock issuable
          pursuant to the terms of any Convertible Securities shall be the
          consideration, if any, received by the Corporation for issuing
          warrants or other rights to subscribe for or purchase such Convertible
          Securities, plus the consideration paid or payable to the Corporation
          in respect of the subscription for or purchase of such Convertible
          Securities, plus the additional consideration, if any, payable to the
          Corporation upon the exercise of the right of conversion or exchange
          in such Convertible Securities. In case of the issuance at any time of
          any Additional Shares of Common Stock or Convertible Securities in
          payment or satisfaction of any dividends upon any class of stock other
          than Common Stock, the Corporation shall be deemed to have received
          for such Additional Shares of Common Stock or Convertible Securities a
          consideration equal to the amount of such dividend so paid or
          satisfied.

               (ii)   When Adjustments to Be Made. The adjustments required by
          this Section 6 shall be made whenever and as often as any specified
          event requiring an adjustment shall occur. For the purpose of any
          adjustment, any specified event shall be deemed to have occurred at
          the close of business on the date of its occurrence.

               (iii)  When Adjustment Not Required. If the Corporation shall
          take a record of the holders of its Common Stock for the purpose of
          entitling them to receive a dividend or distribution or subscription
          or purchase rights and shall, thereafter and before the distribution
          to stockholders thereof, legally abandon its plan to pay or deliver
          such dividend, distribution, subscription or purchase rights, then
          thereafter no adjustment shall be required by reason of the taking of
          such record and any such adjustment previously made in respect thereof
          shall be rescinded and annulled.

                                      16


               (iv)   Escrow of Common Stock. If after any property becomes
          distributable as a result of the provisions of this Section 6 by
          reason of the taking of any record of the holders of Common Stock, but
          prior to the occurrence of the event for which such record is taken, a
          holder of shares of Series A Convertible Preferred Stock exercises its
          conversion rights pursuant to Section 5, any Additional Shares of
          Common Stock issuable and other property distributable upon exercise
          by reason of such adjustment shall be held in escrow for such holder
          by the Corporation to be issued to such holder upon and to the extent
          that the event actually takes place. Notwithstanding any other
          provision to the contrary herein, if the event for which such record
          was taken fails to occur or is rescinded, then such escrowed shares
          shall be canceled by the Corporation and escrowed property returned.

               (v)    Challenge to Good Faith Determination. Whenever the Board
          of Directors shall be required to make a determination in good faith
          of the fair value of any item under this Section 6, such determination
          may be challenged in good faith by a holder of shares of Series A
          Convertible Preferred Stock, and any dispute shall be resolved by an
          investment banking firm of recognized national standing selected by
          the Corporation and acceptable to such holder.

          (i)  Other Action Affecting Common Stock.  In case at any time or from
time to time the Corporation shall take any action in respect of its Common
Stock, other than any action described in this Section 6 for which a specific
adjustment is provided, then, unless such action will not have a materially
adverse effect upon the rights of the holders of shares of Series A Convertible
Preferred Stock, the number of shares of Common Stock or other stock into which
such shares of Series A Convertible Preferred Stock are convertible and/or the
applicable Conversion Price shall be adjusted in such manner as may be equitable
in the circumstances.

          (j)  Certain Limitations.  Notwithstanding anything herein to the
contrary, the Corporation shall not enter into any transaction which, by reason
of any adjustment hereunder, would cause the applicable Conversion Price to be
less than the par value per share of Common Stock.

          (k)  Notice of Adjustments.  Whenever the number of shares of Common
Stock into which shares of Series A Convertible Preferred Stock are convertible
or whenever the applicable Conversion Price shall be adjusted pursuant to this
Section 6, the Corporation shall forthwith prepare a certificate to be executed
by the chief financial officer of the Corporation setting forth, in reasonable
detail, the event requiring the adjustment and the method by which such
adjustment was calculated (including a description of the basis on which the
Board of Directors determined the fair value of any consideration referred to in
Section 6(h)(i)), specifying any change in the applicable Conversion Price or
the number of shares of Common Stock into which shares of Series A Convertible
Preferred Stock are convertible and (if such adjustment was made pursuant to
Section 5(g)(i) or 6(h)) describing the number and kind of any other shares of
stock or Other Property into which shares of Series A Convertible Preferred
Stock are

                                      17


convertible, and any change in the applicable Conversion Price or prices
thereof, after giving effect to such adjustment or change. The Corporation shall
promptly cause a signed copy of such certificate to be delivered to the holders
of Series A Convertible Preferred Stock. The Corporation shall keep at the
Payment Office copies of all such certificates and cause the same to be
available for inspection at said office during normal business hours by the
holders of Series A Convertible Preferred Stock or any prospective purchaser of
shares of Series A Convertible Preferred Stock designated by such holders.

     7.   TRIGGERING EVENTS.

          Any of the following actions or events shall constitute a "Triggering
Event" for purposes hereof:

          (a)  Failure to Pay Dividends.  The Corporation shall fail to pay any
dividend on any Series A Convertible Preferred Stock which it is required to pay
in accordance with Section 2 for any reason, including but not limited to, that
such payment is prohibited by applicable law or the Board of Directors elect not
to pay such dividend, or shall otherwise violate any term of Section 2 and such
failure shall not be cured within a period of 30 days after such violation
(which cure shall be effected in a manner ensuring the holders the same yield as
if such violation had not occurred).

          (b)  Failure of Voting Rights.  The Corporation shall enter into any
transaction or take any action required to be approved by holders of Series A
Convertible Preferred Stock without obtaining the requisite approval of the
holders of the Series A Convertible Preferred Stock.

          (c)  Failure to Convert.  The Corporation shall fail for any reason to
issue Common Stock as required under Section 5 upon the request of any holder of
Series A Convertible Preferred Stock as provided in Section 5 or shall fail for
any reason to comply in any material respect with any term of Section 5(f) or
any other term of Section 5 hereof.

          (d)  Registration Rights Agreement.  The Corporation shall fail in any
material respect to comply with the rights of the holders of Series A
Convertible Preferred Stock pursuant to the Amended and Restated Registration
Rights Agreement, dated as of _________, 2001, among the Corporation, UBS and
other stockholders of the Corporation, and such failure shall continue for a
period of 30 days after notice from any such holder.

          (e)  Series A Stock Purchase Agreement.  The Corporation shall fail to
comply with Section 3, 6(e) or 6(g) of the Series A Stock Purchase Agreement and
such failure shall continue for a period of 30 days after notice from the
Purchasers or the representations made under Section 4(c) or 4(u) of the Series
A Stock Purchase Agreement shall prove to have been incorrect or misleading in
any material respect when made pursuant thereto or any other material
representation made under the Series A Stock Purchase Agreement shall prove to
have been incorrect or misleading in any substantial material respect when made.

                                      18


          (f)  Notwithstanding the foregoing, if the Series A Preferred
Directors affirmatively vote in favor of a transaction or other action by the
Corporation which would constitute a Triggering Event under Section 7(b) or
7(d), such action or event shall not be considered a Triggering Event.

     8.   REMEDIES.

          (a)  In the event that a Triggering Event described in Section 7 shall
occur and be continuing, each holder of Series A Convertible Preferred Stock
shall be entitled to receive all cash and other dividends, distributions and
other payments which would be paid or payable to a holder of a number of shares
of Common Stock into which the shares of Series A Convertible Preferred Stock
held by such holder are convertible at such time (without regard to the number
of shares of Common Stock which are authorized or reserved for issuance at such
time).

          (b)  Upon the occurrence and during the continuance of any Triggering
Event, the size of the Board of Directors shall immediately be increased by the
minimum number of directors which, if all of such additional directors were
deemed "Series A Preferred Directors," would result in Series A Preferred
Directors constituting a majority of the Board of Directors and the holders of
Series A Convertible Preferred Stock shall be entitled to appoint such newly
created directors; provided, however, that upon the occurrence of any Triggering
                   --------  -------
Event which is also a "Triggering Event" as defined in the Series B Certificate,
the holders of the Series A Convertible Preferred Stock and the holders of the
Series B Convertible Preferred Stock shall be entitled to appoint, by voting
together as a single class, a majority of the Board of Directors with each of
such holders having one vote for each full share of Common Stock into which
their shares of Series A Convertible Preferred Stock and/or Series B Convertible
Preferred Stock, as the case may be, are convertible on the record date for the
vote.

          (c)  Upon the occurrence and during the continuance of any Triggering
Event, any holder of shares of Series A Convertible Preferred Stock, at its
election, may, by notice to the Corporation (the "Put Notice"), demand
repurchase of all or any portion of such holder's shares of Series A Convertible
Preferred Stock for a cash purchase price in an amount per share equal to the
Liquidation Preference.  The Corporation shall, on the date (not less than 10
business days after the date of the Put Notice) designated in such Put Notice,
repurchase from the Holder such holder's shares of Series A Convertible
Preferred Stock specified in the Notice.  On the date of any repurchase of
shares of Series A Convertible Preferred Stock pursuant to this Section 8(c),
the holder thereof shall surrender for redemption a certificate for the number
of shares of Series A Convertible Preferred Stock being redeemed, without any
representation or warranty (other than that the holder has good and marketable
title thereto, free and clear of liens, encumbrances and restrictions of any
kind), against payment therefor of the repurchase price by, at the option of the
holder, (i) wire transfer to an account designated by the holder for such
purpose or (ii) a certified or official bank check payable to the order of the
holder.  If less than all of the holder's shares of Series A Convertible
Preferred Stock represented by a single certificate are being redeemed, the
Corporation shall cancel such certificate and issue in the name of, and deliver
to, the holder a new certificate for the portion not being redeemed.  At any
time following delivery of a Put Notice but prior to the date of repurchase, any
holder of Series A Convertible Preferred

                                      19


Stock may, by notice to the Corporation, withdraw the repurchase demand
contained in the Put Notice.

          (d)  The Corporation stipulates that the remedies at law of each
holder of Series A Convertible Preferred Stock in the event of any Triggering
Event or threatened Triggering Event or otherwise or other failure in the
performance of or compliance with any of the terms hereof are not and will not
be adequate and that, to the fullest extent permitted by law, such terms may be
specifically enforced by a decree for the specific performance of any agreement
contained herein or by an injunction against a violation of any of the terms
hereof or otherwise without requiring any holder to post a bond or other
security except to the extent required by applicable law.

          (e)  Any holder of Series A Convertible Preferred Stock shall be
entitled to recover from the Corporation the reasonable attorneys' fees and
expenses incurred by such holder in connection with any Triggering Event or
enforcement by such holder of any obligation of the Corporation hereunder.

          (f)  No failure or delay on the part of any holder of Series A
Convertible Preferred Stock in exercising any right, power or remedy hereunder
or under applicable law or otherwise shall operate as a waiver thereof; nor
shall any single or partial exercise of any such right, power or remedy preclude
any other or further exercise thereof or the exercise of any other right, power
or remedy hereunder or thereunder.  The remedies herein provided are cumulative
and not exclusive of any remedies provided by law or otherwise.

     9.   PREEMPTIVE RIGHT.

          (a)  Each holder of Series A Convertible Preferred Stock or Common
Stock issued upon conversion of Series A Convertible Preferred Stock, shall have
a right of first refusal (the "Preemptive Right") to purchase its pro rata
share, based on such holder's percentage ownership interest in the Corporation,
of New Securities (as defined below) which the Corporation, from time to time,
proposes to sell and issue (subject to such requirements and restrictions
imposed by the Securities Act of 1933, as amended, and state securities laws and
to the actual issuance of the New Securities).  The pro rata shares of any
holder of Series A Convertible Preferred Stock or Common Stock issued upon
conversion of Series A Convertible Preferred Stock, for purposes of this
Preemptive Right, shall be the ratio of (i) the number of shares of Common Stock
owned, of record or beneficially, by such holder (including all shares issuable
upon conversion of the Series A Convertible Preferred Stock or the exercise or
conversion of any other option, warrant or convertible security held by such
holder) immediately prior to the issuance of the New Securities, to (ii) the
total number of shares of Common Stock issued and outstanding immediately prior
to the issuance of the New Securities, determined on a fully diluted basis after
giving effect to the exercise in full of then outstanding options and warrants
and the conversion of all securities convertible into shares of Common Stock;
provided, however, that if any holder of Series A Convertible Preferred Stock or
- --------  -------
Common Stock issued upon conversion of Series A Convertible Preferred Stock does
not elect to purchase its entire pro rata share of such New Securities, then
each other holder that has elected to purchase its entire

                                      20


pro rata share shall have the right to purchase up to a number of such
unpurchased portion, in addition to its own, in the proportion that (1) the
number of shares of Common Stock owned, of record or beneficially, by such
holder (including all shares issuable upon conversion of the Series A
Convertible Preferred Stock or the exercise or conversion of any other option,
warrant or convertible security held by such holder) immediately prior to the
issuance of the New Securities bears to (2) the number of shares of Common Stock
owned, of record or beneficially, by all holders of Series A Convertible
Preferred Stock or Common Stock issued upon conversion of Series A Convertible
Preferred Stock (including all shares issuable upon conversion of the Series A
Convertible Preferred Stock or the exercise or conversion of any other option,
warrant or convertible security held by such holders) immediately prior to the
issuance of the New Securities. The overallotment mechanism set forth in this
paragraph shall be repeatedly applied until all New Securities available for
purchase by holders of Series A Convertible Preferred Stock or Common Stock
issued upon conversion of Series A Convertible Preferred Stock have been
purchased or no holders remain who have indicated a desire to purchase any
unsubscribed for portion in their notice to the Corporation.

          (b)  "New Securities" shall mean (a) any capital stock of the
Corporation, rights, options or warrants to purchase capital stock and
securities of any type whatsoever that are, or may become convertible into or
exchangeable for capital stock and (b) so-called "high yield" bonds, debt
instruments with equity like features or other similar debt instruments, which
bear a rating lower than investment-grade or are unrated, issued by the
Corporation; provided, however, that the term "New Securities" does not include
             --------  -------
(i) the issuance of up to 4,243,037 shares of Common Stock issuable pursuant to
options to purchase Common Stock under the Stock Option Plan,  (ii) shares of
Common Stock issued or issuable in connection with a Qualified Public Offering,
(iii) shares of Common Stock issued upon conversion of Series A Convertible
Preferred Stock or Series B Convertible Preferred Stock, (iv) securities issued
as consideration for any acquisition approved by a majority of the Board of
Directors (including the affirmative vote of the Series A Preferred Directors ),
(v) the Spinway Warrant, (vi) 210,000 shares of Common Stock upon exercise of
the Spinway Warrant, (vii) shares of Common Stock in exchange for shares of
Tutopia Stock upon a change-in-control of the Corporation pursuant to the
Tutopia Stockholders Agreement, or (viii) any shares of capital stock of the
Corporation, rights, options or warrants to purchase capital stock and
securities of any type whatsoever that are, or may become convertible into or
exchangeable for capital stock after first receiving the affirmative vote or
written consent of the holders of a majority of the shares of Series A
Convertible Preferred Stock.

          (c)  In the event the Corporation proposes to undertake an issuance of
New Securities, it shall give each holder of Series A Convertible Preferred
Stock or Common Stock issued upon conversion of Series A Convertible Preferred
Stock written notice of its intention, describing the type of New Securities and
the price and the terms upon which the Corporation proposes to issue the same.
Each such holder shall have twenty (20) business days from the date of receipt
of any such notice to agree to purchase its pro rata share of such New
Securities for the price and upon the terms specified in the notice by giving
written notice to the Corporation and stating therein the quantity of New
Securities to be purchased.

                                      21


          (d)  The Corporation shall have ninety (90) days after expiration of
the twenty (20) business day period described in Section 9(c) to sell any New
Securities with respect to which a Preemptive Right was not exercised, at a
price not less than and upon terms no more favorable in the aggregate to the
purchasers thereof than specified in the Corporation's notice. To the extent the
Corporation does not sell all the New Securities offered within said ninety (90)
day period, the Corporation shall not thereafter issue or sell such New
Securities without first again offering such securities to each holder of Series
A Convertible Preferred Stock or Common Stock issued upon conversion of Series A
Convertible Preferred Stock in the manner provided above.

          (e)  The rights granted under this Section 9 to each holder of Series
A Convertible Preferred Stock or Common Stock issued upon conversion of Series A
Convertible Preferred Stock shall expire upon the earlier of (i) the closing of
a Qualified Public Offering and (ii) such time as there is no longer outstanding
at least 50% of the number of shares of Series A Convertible Preferred Stock
(including, for this purpose, Common Stock issued upon conversion of the Series
A Convertible Preferred Stock) issued pursuant to the Series A Stock Purchase
Agreement (as adjusted in connection with the events described in Section 6)
determined after the Subsequent Closing (as defined in the Series A Stock
Purchase Agreement).


     10.  RANKING.

          The Series A Convertible Preferred Stock shall rank pari passu with
the Series B Convertible Preferred Stock of the Corporation (which shall
constitute Parity Securities for purposes hereof) with respect to amounts
receivable upon a Liquidation Event, dividends, rights and remedies upon
Triggering Event or for any other purpose.

                                      22
