                                 PROXY STATEMENT

                         ANNUAL MEETING OF STOCKHOLDERS

                               November ____, 2001

     The Board of Directors of IFX Corporation ("IFX" or the "Company") is
asking for your proxy for use at the annual meeting of stockholders of IFX to be
held on December 7, 2001 at 10:00 a.m. local time and at any postponements or
adjournments of the meeting. The meeting will be held at the principal executive
offices of the Company located at 15050 N.W. 79 Court, Suite 200, Miami Lakes,
Florida 33016. We are initially mailing this proxy statement and the enclosed
proxy to stockholders of IFX on or about November 28, 2001.

                                ABOUT THE MEETING

What is the purpose of the annual meeting?

     At our annual meeting, stockholders will act upon the matters outlined in
the accompanying notice of meeting, including the authorization of the amendment
of the Restated Certificate of Incorporation of the Company, authorization of
the issuance of the New Stock, authorization of the amendment of the
Certificates of Designation for the Company's Series A Convertible Preferred
Stock and Series B Convertible Preferred Stock, election of eight directors and
the ratification of Ernst & Young, LLP as our auditors.

What are IFX's voting recommendations?

     Our Board of Directors recommends that you vote your shares "FOR" the
amendment of the Restated Certificate of Incorporation, "FOR" the issuance of
the New Stock, "FOR" the amendment of the Series A Convertible Preferred Stock
and Series B Convertible Preferred Stock Certificates of Designation, "FOR" each
of the nominees to the Board of Directors and "FOR" the ratification of Ernst &
Young, LLP as our auditors.

Who is entitled to vote?

     Only stockholders of record at the close of business on November 1, 2001
are entitled to notice of the annual meeting and to vote at the annual meeting
or any postponements or adjournments thereof. Each share of Common Stock
entitles the holder to one vote on each matter to be voted on. For all matters
submitted to a vote of stockholders, each share of the Company's Series A
Preferred Stock and Series B Preferred Stock (collectively, the "Preferred
Stock") entitles the holder to one vote for each share of Common Stock into
which the holder's



Preferred Stock is convertible on the record date. For all matters submitted to
stockholders for a vote, the holders of the Preferred Stock vote with the
holders of Common Stock as a single class. However, holders of Class II Series B
Preferred Stock do not vote for directors. In addition, the holders of each of
the Series A Preferred Stock and Series B Preferred Stock, each voting as a
single class, must approve the amendment of the Restated Certificate of
Incorporation, the issuance of the New Stock and the amendments to the
Certificates of Designation. The holders of the Series A Preferred Stock voting
as a single class are entitled to designate two directors and the holders of the
Class I Series B Preferred Stock voting as a single class are entitled to
designate one director.

What constitutes a quorum?

     If stockholders holding a majority of the stock of the Company entitled to
vote on the record date are present at the annual meeting, either in person or
by proxy, we will have a quorum at the meeting, permitting the conduct of
business at the meeting. Any shares represented by proxies that are marked to
abstain from voting on a proposal will be counted as present for purposes of
determining whether we have a quorum. If a broker, bank, custodian, nominee or
other record holder of IFX Common Stock indicates on a proxy that it does not
have discretionary authority to vote certain shares on a particular matter, the
shares held by that record holder (referred to as "broker non-votes") will also
be counted as present in determining whether we have a quorum.

     As of the record date, there were 14,276,495 shares of Common Stock issued
and outstanding and entitled to vote, 2,030,869 shares of Series A Preferred
Stock issued and outstanding, 3,994,127 shares of Class I Series B Convertible
Preferred Stock issued and outstanding, and 424,135 shares of Class II Series B
Convertible Preferred Stock issued and outstanding. As of such date, the issued
and outstanding shares of Series A Preferred Stock were convertible into
7,142,857 shares of Common Stock giving the Series A Preferred Stock the right
to vote 7,142,857 shares. The issued and outstanding shares of Series B
Preferred Stock were convertible into 4,418,262 shares of Common Stock giving
the Series B Preferred Stock the right to vote 4,418,262 shares (3,994,127
shares in the election of directors because the Class II Series B Preferred
Stock do not vote in the election of directors).

What vote is required to approve each item?

     Director nominees must receive the affirmative vote of a plurality of the
shares represented at the meeting and entitled to vote, meaning that the eight
nominees for director with the most votes will be elected. The remaining
proposals require the affirmative vote of a majority of the votes entitled to be
cast by holders of shares of Common Stock and Preferred Stock represented at the
meeting. In addition, the proposals regarding amending the Restated Certificate
of Incorporation, the authorization of the issuance of the New Stock and
amending the Preferred Stock Certificates of Designation require the approval of
a majority of the Series A Preferred Stock and Series B Preferred Stock.
Abstentions and broker non-votes will not be counted for purposes of determining
whether an item has received the requisite number of votes for approval.

                                        2



     IFX, Lee S. Casty ("Casty"), Joel M. Eidelstein ("Eidelstein"),
International Technology Investments, LC ("ITI"), Michael Shalom ("Shalom"), and

Stockholders' Agreement (the "Current Stockholders' Agreement") dated as of May
7, 2001. Under the Current Stockholders' Agreement, Casty, Eidelstein, ITI,

nominated jointly by Mr. Eidelstein and ITI (currently, George Myers); and two

IFX, Casty, Eidelstein, ITI, Shalom, UBS and the Company have also entered into
a Voting Agreement dated as of October 11, 2001 (the "Voting Agreement"), in
which each of the parties agrees to vote their voting shares of the Company in
favor of the proposals to amend the Company's Restated Certificate of
Incorporation, to issue the New Stock, and to amend the Preferred Stock
Certificates of Designation.

     Under the terms of the Current Stockholders Agreement and the Voting
Agreement, the parties to such agreements have agreed to vote all of the stock
of the Company owned by such parties and entitled to vote on each of the
proposals (except for the ratification of our auditors) "FOR" each of the
proposals submitted by the Board of Directors and all such proposals will be
approved.

How do I vote?

     You may vote in person at the annual meeting or you may vote by proxy by
signing, dating and mailing the enclosed proxy card. If you vote by proxy, the
individuals named on the card as proxy holders will vote your shares in the
manner you indicate. If you sign and return the card without indicating your
instructions, your shares will be voted "FOR":

  .  The amendment to the Restated Certificate of Incorporation of the Company,
  .  The authorization of the issuance of the New Stock,
  .  The amendment of the Certificates of Designation for the Series A and B
     Preferred Stock,
  .  The election of the eight nominees for director, and
  .  The ratification of Ernst & Young as our auditors.

Can I vote by telephone or electronically?

     No.

Can I change my vote after I return my proxy card?

     Yes. Even after you have submitted your proxy, you may change your vote at
any time before the proxy is exercised at the annual meeting by delivering to
the Secretary of IFX a written notice of revocation or a properly signed proxy
bearing a later date, or by attending the annual meeting and voting in person
(although attendance at the meeting will not cause your previously granted proxy
to be revoked unless you specifically so request).

                                       3



What happens if additional proposals are presented at the meeting?

     Other than the matters described in this proxy statement, we do not expect
any additional matters to be presented for a vote at the annual meeting. If you
vote by proxy, your proxy grants the persons named as proxy holders the
discretion to vote your shares on any additional matters properly presented for
a vote at the meeting.

Who will bear the costs of soliciting votes for the meeting?

     IFX will bear the entire cost of the solicitation of proxies from its
stockholders. In addition to the mailing of these proxy materials, the
solicitation of proxies or votes may be made in person, by telephone or by
electronic communication by our directors, officers and employees, who will not
receive any additional compensation for such solicitation activities. We will
also reimburse brokerage houses and other custodians, nominees and fiduciaries
for their reasonable out-of-pocket expenses for forwarding proxy and
solicitation materials to our stockholders. Except as described above, IFX does
not presently intend to solicit proxies other than by mail.

                            PROPOSALS TO BE VOTED ON

     Background.

     In order to meet its working capital needs, on October 11, 2001, the
Company entered into an agreement (the "New Stock Purchase Agreement") with UBS
for the purchase by UBS of 3,833,333 shares of the Company's Series C
Convertible Preferred Stock (the "Series C Preferred

                                        5



Stock") in consideration of $7,000,000 in cash and the surrender to the Company
of 1,500,000 shares of Common Stock currently owned by UBS.

     The Company and UBS agreed in the New Stock Purchase Agreement to certain
conditions to the closing of the sale of Series C Preferred Stock to UBS (the
"Closing"). The Company agreed to amend its Restated Certificate of
Incorporation to authorize the issuance of more shares of capital stock and to
amend its Certificates of Designation for the Series A Preferred Stock and
Series B Preferred Stock to reflect the issuance of the Series C Preferred
Stock, add participation rights to the Series A Preferred Stock and Series B
Preferred Stock, and make certain other changes. At Closing, the Company and UBS
will enter into a Put Agreement (the "Put") granting UBS, as a stockholder of
Tutopia.com, Inc. ("Tutopia"), the right to exchange its equity investment in
Tutopia (in which IFX holds a minority investment) for additional shares of
convertible preferred stock of IFX within one year. IFX has agreed to permit the
other stockholders of Tutopia to exchange their shares of Tutopia for shares of
IFX if UBS exercises such right. The shares of Series C Preferred Stock to be
issued pursuant to the New Stock Purchase Agreement and the additional shares of
convertible preferred stock and common stock that may be issued in connection
with the Put are collectively the shares of "New Stock" referred to in Proposal
Two of this Proxy Statement. A Third Amended and Restated Stockholders Agreement
(the "New Stockholders Agreement"), by and among the Company, UBS, ITI,
Eidelstein, Shalom and Casty and a Second Amended and Restated Registration
Rights Agreement among the Company, UBS, ITI, Eidelstein and Casty will also be
entered into at the Closing. It is a further condition to the Closing that the
Company shall have restructured certain of its outstanding debt obligations.

     UBS has advanced $2,000,000 to IFX to date and may, but is not obligated
to, advance additional funds, to IFX prior to the Closing. This advance by UBS
will be applied against its purchase price for the Series C Preferred Stock. Any
interest owed by IFX to UBS as a result of the advances will be paid in the form
of additional shares of Series C Preferred Stock based on a purchase price of
$3.00 per share.

     The amendment of the Restated Certificate of Incorporation and the
Certificates of Designation requires the approval of the Company's stockholders
under the Delaware General Corporation Law. The issuance of the shares of New
Stock requires approval of the Company's stockholders according to the
stockholder approval requirements of Nasdaq.

     Effect On Ownership Percentage of Company.

     Prior to the Closing, UBS holds 2,030,869 shares (or 100% of the issued and
outstanding shares) of Series A Preferred Stock, 4,418,262 shares (or 100% of
the issued and outstanding shares) of Series B Preferred Stock consisting of
Class I Series B Preferred Stock and Class II Series B Preferred Stock, and
1,500,000 shares of Common Stock. The Series A Preferred Stock is currently
convertible into 7,142,857 shares of Common Stock and the Series B Preferred
Stock is currently convertible into 4,418,262 shares of Common Stock. The Class
II Series B Preferred Stock is convertible into Class I Series B Preferred Stock
on a share for share basis beginning May 3, 2002. After the issuance of the
Series C Preferred Stock, the Series A Preferred Stock owned by UBS would be
convertible into 8,333,333 shares of Common Stock, the shares of Series B
Preferred Stock owned by UBS would be convertible into approximately 5,154,640

                                       6



shares of Common Stock, and the 3,833,333 shares of Series C Preferred Stock
would be convertible into 3,833,333 shares of Common Stock. If UBS and other
stockholders of Tutopia exercise the Put, additional shares of Common Stock and
an additional series of convertible preferred stock of the Company could be
issued that could, on a fully-converted basis, equal approximately 8.6 million
shares of Company stock (over 59% of the currently outstanding Common Stock).

     Effect On General Voting Power.

     In all matters requiring stockholder approval, in addition to any required
class vote of the Series A Preferred Stock or Series B Preferred Stock, the
holders of all shares of the Company's issued and outstanding classes of stock
vote together as a single class (other than Class II Series B Preferred Stock
which does not vote in the election of directors). Prior to the Closing, UBS
controls 13,061,119 votes (or approximately 50.3%). After the Closing, UBS will
control approximately 17,321,059 votes (or approximately 57.39%) assuming
certain IFX debt covenants are waived. If such covenants are not waived, UBS
will receive a portion of its additional equity in the form of non-voting
preferred stock and will own less than 50% of Company stock entitled to vote for
directors. If the Put is exercised by UBS, it would control approximately
22,931,056 votes (or approximately 59.1%).

     Effect On Vote For Election Of Directors.

     After the Closing, the holders of Common Stock, Series A Preferred Stock,
Class I Series B Preferred Stock and Class I Series C Preferred Stock will be
entitled to vote in the election of directors of the Company. If the Company
receives a waiver of certain outstanding debt covenants, holders of the Series A
Preferred Stock, Class I Series B Preferred Stock and Class I Series C Preferred
Stock will be entitled to designate four directors as a class. In such case, the
parties to the New Stockholders Agreement (who control 65% of the outstanding
voting stock) have agreed to elect, seven members to the Board, of whom three
shall be designated by UBS (initially, Charles W. Moore, Mark O. Lama and
Charles Delaney), one shall be the designated by ITI (initially, Michael
Shalom), one shall be designated by Casty (initially, Joel Eidelstein), one
shall be an independent director (as defined by the NASD) designated by UBS
(initially, Patrick Delhougne), and one shall be an independent director
reasonably acceptable to UBS, Casty and ITI (initially, Burton Meyer). Mr.
Moore, Mr. Lama, Mr. Delaney and Mr. Delhougne will each also initially count as
one of the four directors that the holders of the Preferred Stock are entitled
to elect as a class. If the Company does not receive a waiver of certain
outstanding debt covenants, the New Stockholders Agreement provides that the
Board will have nine directors, of whom five shall be designated by UBS
(initially, Charles W. Moore, Mark O. Lama, Charles Delaney and two additional
directors designated by UBS), one shall be designated by ITI (initially, Michael
Shalom), one shall be designated by Casty (initially, Joel Eidelstein) and two
shall be independent directors reasonably acceptable to UBS, Casty and ITI
(initially, Patrick Delhougne and Burton Meyer).

                                       7



                                  PROPOSAL ONE:
               AMENDMENT OF RESTATED CERTIFICATE OF INCORPORATION

     IFX's Restated Certificate of Incorporation authorizes the issuance of
50,000,000 shares of Common Stock, $.02 par value and 10,000,000 shares of
Preferred Stock, $1.00 par value. As of November 1, 2001, 14,276,495 shares of
Common Stock were issued and outstanding, and 17,058,887 shares of Common Stock
were reserved for issuance by the Company upon the exercise of options and
warrants and the conversion of the Preferred Stock. As of November 1, 2001,
6,449,131 shares of Preferred Stock were issued and outstanding, which shares
are divided into two series of Convertible Preferred Stock. After the Closing,
12,776,495 shares of Common Stock will be issued and outstanding and 10,282,464
shares of Preferred Stock will be issued and outstanding. If the Put is
exercised in full by UBS and other Tutopia stockholders, approximately
14,061,355 shares of Common Stock would be issued and outstanding and 17,559,131
shares of Preferred Stock would be issued and outstanding. The Board of
Directors recommends that the authorized number of shares of Common Stock be
increased from 50,000,000 shares to 60,000,000 shares, and also that the
authorized number of shares of Preferred Stock be increased from 10,000,000
shares to 20,000,000 shares.

     The transactions pursuant to the New Stock Purchase Agreement and the Put
require that the Company increase the number of common and preferred shares
available. The Board believes, based on the number of shares of Common Stock and
Preferred Stock currently outstanding and the number of shares the Company
reasonably expects to issue in financings, acquisitions, conversion of preferred
shares, and other transactions, that 50,000,000 is an insufficient number of
shares of Common Stock, and that 10,000,000 is an insufficient number of shares
of Preferred Stock for the Company to be authorized to issue without additional
stockholder approval. Accordingly, the Board of Directors believes that an
increase in the number of authorized shares of Common Stock and Preferred Stock
would be in the best interests of the Company and that 60,000,000 authorized
shares of Common Stock and 20,000,000 shares of Preferred Stock will suffice to
maintain the requisite amount of flexibility required by the Company's ongoing
activities as currently contemplated.

     If the amendments to the Restated Certificate of Incorporation are adopted,
Article 4 of the Restated Certificate of Incorporation will be amended and
restated to read as shown on Exhibit A.
                             ----------

     Vote Required

     The proposal to amend the Restated Certificate of Incorporation requires
the affirmative vote of the holders of a majority of the votes entitled to be
cast by holders of all outstanding shares of the Series A Preferred Stock and
the affirmative vote of the holders of a majority of the votes entitled to be
cast by holders of all outstanding shares of the Series B Preferred Stock. This
proposal also requires the affirmative vote of the holders of a majority of the
votes entitled to be cast by the holders of all outstanding shares of Common
Stock, Series A Preferred Stock and Series B Preferred Stock, voting together as
a single class.

     Under the terms of the Voting Agreement, the holders of all of the
Preferred Stock and the holders of approximately 65% of the outstanding shares
of the Common Stock have agreed to

                                       8



vote for the approval of the Amendment to the Restated Certificate of
Incorporation. Accordingly, the proposal will be approved at the Annual Meeting.

     Recommendation of the Board of Directors

     The Board of Directors recommends that stockholders vote FOR the amendment
to the Company's Restated Certificate of Incorporation to increase the number of
shares of Common Stock and Preferred Stock the Company is authorized to issue.

                                  PROPOSAL TWO:
                              ISSUANCE OF NEW STOCK

     The Company's listing agreement with Nasdaq requires stockholder approval
of the issuance of common stock, or stock convertible into common stock, if such
issuance will result in a change of control of the Company. Since upon the
issuance of the Series C Preferred Stock, UBS will be able to designate a
majority of the Board of Directors and may own over 50% of the Company's voting
stock, the Company is seeking the approval of stockholders for this issuance.

     Following the issuance of the Series C Preferred Stock, each share of
Series A Preferred Stock will be convertible into approximately 4.10 shares of
Common Stock, and each share of Series B Preferred Stock will be convertible
into approximately 1.17 shares of Common Stock. There are currently 14,276,495
shares of Common Stock which have been issued and are outstanding. Following
issuance of all of the Series C Preferred Stock and assuming the immediate
conversion of all of the Series A Preferred Stock, Series B Preferred Stock and
Series C Preferred Stock into Common Stock, the total number of shares of Common
Stock would increase to approximately 30 million shares, an increase of 210%.
UBS would hold approximately 17.3 million shares, or approximately 58%, of these
shares.

     In addition, if UBS and all other stockholders of Tutopia (other than the
Company) exercise the Put, additional shares of Common Stock and an additional
series of convertible preferred stock of the Company could be issued that, on a
fully-converted basis, equal approximately 8.6 million shares of Company stock
(over 59% of the currently outstanding Common Stock) at a price that could be
below the greater of book or market value of the Common Stock at the time of the
issuance of the new convertible preferred stock. Such an issuance would also
require the approval of stockholders under Nasdaq rules. Under the Put, the new
series of convertible preferred stock would have the same terms as the Series C
Preferred Stock as described below except for the participation feature in the
event of liquidation.

     Terms of the Series C Preferred Stock

     The following is a summary of the material terms of the Series C Preferred
Stock:

          Rank. For dividends or distribution of assets upon liquidation,
          dissolution or winding up of the Company, the Series C Preferred Stock
          will rank pari passu with the Series A Preferred Stock and the Series
          B Preferred Stock, and all three classes of Preferred Stock rank
          senior to the Common Stock.

                                        9



          Liquidation. In the event of any bankruptcy, liquidation, dissolution
          or winding up of the Company, the holders of the Series C Preferred
          Stock will receive a liquidation preference equal to the sum of (a)
          $3.00 per share plus all accrued but unpaid dividends (if any) plus
          $0.30 per share per year from the date of issuance of the shares to
          the liquidation date (the "Stated Preference"), plus (b) an amount
          equal to the per share amount the Series C Preferred Stock would have
          been paid if each share of Series C Preferred Stock and all other
          outstanding shares of Preferred Stock had been converted into Common
          Stock immediately prior to any such liquidation event, after the full
          payment of its Stated Preference and the stated preference of the
          other Preferred Stock.

          However, the amount payable per share of Series C Preferred Stock as a
          liquidation preference cannot exceed three and one-half (3-1/2)
          multiplied by the Stated Preference.

          Voting Rights. Each share of Series C Convertible Preferred Stock will
          be entitled to one vote for each share of Common Stock into which the
          Series C Preferred Stock is convertible. The holders of the Series C
          Preferred Stock are entitled to vote with the holders of the Common
          Stock, the holders of the Series A Preferred Stock and the holders of
          the Class I Series B Preferred Stock, as a single class, on all
          matters presented to the holders of the Common Stock. Additionally,
          the holders of the Series A, Class I Series B and Class I Series C
          Preferred Stock voting together as a class will be entitled to appoint
          a majority of the Board of Directors.

          Restrictions. Without the consent of a majority of the holders of the
          Series A Preferred Stock, Series B Preferred Stock and Series C
          Preferred Stock voting together as a single class, the Company may not
          take any of the following actions:

               amend, repeal, modify or supplement any provision of the
               Company's Certificate of Incorporation or Bylaws;

               issue any capital stock or any options, warrants or other rights
               exchangeable or exercisable therefor (with certain permitted
               exceptions);

               pay any dividends on or repurchase, redeem or retire the Common
               Stock;

               reclassify any class or series of any Common Stock into shares
               having any preference or priority as to dividends or liquidation
               superior to or on a parity with any such preference or priority
               of Series C Preferred Stock;

               authorize a liquidation, winding up or dissolution of the Company
               or any acquisition of the Company;

               become party to any agreement where any Company shareholder
               transfers stock to a third party which results in the third party
               possessing the voting power to elect a majority of the Company's
               Board of Directors

                                       10



               approve the annual budget of the Company;

               amend any existing Company stock option plan or (except as
               approved by the Compensation Committee of the Board of Directors)
               adopt any new stock-based compensation plan;

               enter into any financial commitment over and above those approved
               in the annual budget in excess of $15 million in the aggregate;

               dismiss or hire or modify or enter into any employment agreement,
               or other compensation arrangements with any senior officer of the
               Company;

               permit the creation or existence of any lien on any of the
               Company's assets with an aggregate value in excess of $15
               million;

               make any capital expenditure in any fiscal year in excess of $15
               million in the aggregate except as prescribed in the approved
               annual budget;

               acquire any assets or equity or other interest in any other
               entity with a value in excess of $15 million in the aggregate
               except as prescribed in the approved annual budget;

               incur indebtedness in excess of $15 million in the aggregate,
               except as prescribed in the approved annual budget;

               dispose of or acquire assets with a value in excess of $15
               million other than in the normal course of business;

               change in any material respect the nature of the Company's
               business;

               enter into any understanding with any affiliate of the Company,
               other than a wholly-owned subsidiary of the Company; or

               solicit or negotiate any proposals with respect to Latin Guide,
               Inc., a subsidiary of the Company, or Tutopia or any of its
               subsidiaries.

          Conversion. Each share of Series C Preferred Stock will initially be
          convertible into one share of Common Stock.

          Adjustments. The conversion rights of the Series C Preferred Stock are
          subject to adjustment in the case of certain events to prevent any
          dilution in the holdings of the holders of the Series C Preferred
          Stock (including, but not limited to, certain issuances of Company
          equity securities at less than $3.00 per share).

          Preemptive Right. Each holder of the Series C Preferred Stock has the
          right to purchase its pro rata share of certain new securities issued
          by the Company.

                                       11

               Stock will rank pari passu with the Series A Preferred Stock and
               the Series B Preferred Stock. All three classes of Preferred
               Stock will rank senior to the Common Stock.

               Liquidation Preference. In the event of any bankruptcy,
               liquidation, dissolution or winding up of the Company, the
               holders of the Series A Preferred Stock will receive a
               liquidation preference equal to the sum of (a) $12.31 per share
               plus all accrued but unpaid dividends (if any) plus $1.23 per
               share per year from the date of issuance of the shares to the
               liquidation date (the "Stated Preference"), plus (b) an amount
               equal to the per share amount the Series A Preferred Stock would

               converted into Common Stock immediately prior to any such
               liquidation event, after the full payment of its Stated
               Preference and the stated preference of the other Preferred
               Stock.

               The holders of the Series B Preferred Stock will receive a
               liquidation preference equal to the sum of (a) $3.50 per share
               plus all accrued but unpaid dividends (if any) plus $0.35 per
               share per year from the date of issuance of the shares to the
               liquidation date (the "Stated Preference"), plus (b) an amount
               equal to the per share amount the Series B Preferred Stock would
               have been paid if each share of the Series B Preferred Stock and

               B Preferred Stock will be entitled to one vote for each share of

               holders of the Series A Preferred Stock, the Series B Preferred
               Stock and the Series C Preferred Stock are entitled to vote with
               the holders of the Common Stock, as a single class, on all

     Recommendation of the Board of Directors

     The Board of Directors of the Company unanimously recommends that the

                                 PROPOSAL FOUR:
                              ELECTION OF DIRECTORS

     Eight directors will be elected at the Annual Meeting to serve for one-year
terms. Except as described below, the Board of Directors has no reason to
believe that any of the nominees will

                                       17



not be a candidate or, if elected, will be unable or unwilling to serve as a
director. In no event will the proxies be voted for a greater number of persons
than the number of nominees named.

     Upon the Closing, under the New Stockholders Agreement, the Board will be
restructured. The parties to the New Stockholders Agreement (who control 65% of
the outstanding voting stock) have agreed to elect, if the Company receives a
waiver of certain outstanding debt covenants, seven members to the Board. If the
Company does not receive a waiver of certain outstanding debt covenants, the New
Stockholder Agreement provides that the Board shall have nine directors and UBS
shall designate the two additional directors. The Board of Directors has
nominated and urges you to vote "FOR" the election of the eight nominees listed
below. In the event a nominee is not available to serve for any reason when the
election occurs, it is intended that the proxies will be voted for the election
of the other nominees and may be voted for any substitute nominee.

                                 PROPOSAL FIVE:
                        RATIFICATION OF THE ENGAGEMENT OF
                                  ERNST & YOUNG

     Ernst & Young LLP audited the Company's financial statements for fiscal
year 2001. The Board of Directors has engaged Ernst & Young LLP to audit the
financial statements of the Company for fiscal year 2002, subject to
ratification by the stockholders.

     It is expected that a representative of Ernst & Young LLP will be available
during the Annual Meeting and will have an opportunity to make a statement, if
such representative so desires, and to respond to appropriate questions.

     Audit Fees

     The aggregate fees billed to the Company by Ernst & Young, LLP as the
Company's independent public accountants for the audit of the fiscal year 2001
financial statements and for the review of the interim financial statements
included in the Company's fiscal year 2001 quarterly reports on Form 10-Q
totaled $474,390.

     Financial Information System Design and Implementation Fees

     The Company did not engage Ernst & Young to provide professional services
to the Company relating to financial information systems design and
implementation during fiscal year 2001.

     All Other Fees

     The aggregate fees billed to the Company by Ernst & Young for services
rendered to the Company during fiscal year 2001, other than the services
described under "Audit Fees" and "Financial Information Systems Design and
Implementation Fees," totaled $94,456. These fees were for tax consulting
services.

                                       20



     As set forth in the Audit Committee Report on page 23, the Audit Committee
has considered the provision of non-audit services described in "All Other Fees"
and has determined it is compatible with maintaining the independence of Ernst &
Young. The Audit Committee will consider in advance of the provision of any
significant non-audit services by Ernst & Young whether the provision of such
services is compatible with maintaining the independence of such accountants.

     _______

     Vote Required

     The ratification of Ernst & Young LLP as independent auditors requires the
affirmative vote of the holders of a majority of the votes entitled to be cast
by holders of all outstanding shares of the Series A Preferred Stock and the
affirmative vote of the holders of a majority of the votes entitled to be cast
by holders of all outstanding shares of the Series B Preferred Stock. This
proposal also requires the affirmative vote of the holders of a majority of the
votes entitled to be cast by the holders of all outstanding shares of Common
Stock, Series A Preferred Stock and Series B Preferred Stock, voting together as
a single class.

     Recommendation of the Board of Directors

     The Board of Directors of the Company unanimously recommends that
stockholders vote FOR ratification of Ernst & Young LLP as independent auditors.

                        BOARD STRUCTURE AND COMPENSATION

     Board of Directors

     Directors are elected on an annual basis. Each director of the Company
holds office until the next annual meeting of stockholders or until that
director's successor has been elected and qualified. The number of directors
that constitute the full board is fixed from time to time by resolution of the
Board of Directors. There are eight persons currently serving as directors.

     After the Closing, the holders of Common Stock, Series A Preferred Stock,
Class I Series B Preferred Stock and Class I Series C Preferred Stock will be
entitled to vote in the election of directors of the Company. If the Company
receives a waiver of certain outstanding debt covenants, holders of the Series A
Preferred Stock, Class I Series B Preferred Stock and Class I Series C Preferred
Stock will be entitled to designate four directors as a class. In such case, the
parties to the New Stockholders Agreement (who control 65% of the outstanding
voting stock) have agreed to elect seven members to the Board, of whom three
shall be designated by UBS (initially, Charles W. Moore, Mark O. Lama and
Charles Delaney), one shall be the designated by ITI (initially, Michael
Shalom), one shall be designated by Casty (initially, Joel Eidelstein), one
shall be an independent director (as defined by the NASD) designated by UBS
(initially, Patrick Delhougne), and one shall be an independent director
reasonably acceptable to UBS, Casty and ITI (initially, Burton Meyer). If this
occurs, George Myers has agreed to resign from the Board.

                                       21



     If the Company does not receive a waiver of certain outstanding debt
covenants, the New Stockholder Agreement provides that the Board shall have nine
directors, of whom five shall be designated by UBS (initially, Charles W. Moore,
Mark O. Lama, Charles Delaney and two additional directors designated by UBS),
one shall be designated by ITI (initially, Michael Shalom), one shall be
designated by Casty (initially, Joel Eidelstein) and two shall be independent
directors reasonably acceptable to UBS, Casty and ITI (initially, Patrick
Delhougne and Burton Meyer. If this occurs, George Myers has agreed to resign
from the Board.

     During fiscal year 2001, the Board of Directors held six meetings and took
all other actions pursuant to unanimous written consents in lieu of meetings.
Each of the current directors attended at least 75% of all meetings of the Board
of Directors during fiscal year 2001 called during the time he or she served.

     Compensation of Directors

     Directors do not receive cash compensation in connection with their duties
as directors, but may be reimbursed for expenses incurred by them in connection
with their services as directors.

     The Company grants stock options under our Directors Stock Option Plan to
each director who is not an IFX employee and who is not a beneficial owner of 5%
or more of the Company's Common Stock (as determined in accordance with Rule
13d-3 of the Securities Exchange Act of 1934). Under this plan, we grant each
non-employee director an option to buy 450 shares of our Common Stock when the
director is first elected and an option to buy an additional 450 shares of
Common Stock at each annual meeting until he or she is no longer a director. If
a director serves on a committee of the board, he or she is granted an
additional option to buy 75 shares for each year of service. The exercise price
for the options is equal to 100% of the fair market value of our Common Stock on
the date of grant. The options cannot be exercised until six months after the
date of grant. Each option terminates on the earlier of a director's termination
for cause, one year after a director's death, or ten years from the date of
grant. Mr. Myers and Mr. Meyer have each been granted options to purchase 1,200
shares of Company Common Stock for their services as directors since November 9,
1999. Mr. Delhougne was granted 450 shares upon his election to the Board on May
2, 2001. Mr. Eidelstein and Mr. Shalom, as employees, and Mr. Delaney, Mr. Moore
and Mr. Lama, as 5% or more beneficial owners, did not receive any options under
the plan.

     Committees of the Board of Directors

     The Board of Directors has a standing Audit Committee and Compensation
Committee to assist the Board in the discharge of its responsibilities. The
current members of the Audit Committee are George A. Myers, Burton J. Meyer and
Mark O. Lama. Mr. Myers. and Mr. Meyer are independent directors as defined by
Rule 4200(a)(15) of the NASD Listing Rules. Under Rule 4460(d)(2)(B) of the
NASD's listing Rules, the Board of Directors believes that it is in the best
interest of IFX and its stockholders to appoint Mr. Lama to the Audit Committee
even though Mr. Lama is not "independent" of IFX according to the NASD Rules.
Mr. Lama's experience and knowledge of the Company through his work with UBS
make him a valuable member of the Audit Committee. Each of the Audit Committee
and the Compensation

                                       22



Committee held one meeting during fiscal year 2001 which was attended by all of
its respective members.

     The Compensation Committee develops and oversees the Company's compensation
policy and approves salaries and annual bonuses for senior management of the
Company. The Compensation Committee currently consists of George Myers, Burton
J. Meyer and Charles W. Moore.

     Report of the Audit Committee

          The Audit Committee of the Board of Directors is composed of two
     independent directors and one non-independent director as defined by and in
     accordance with NASD rules. The Audit Committee operates under a written
     charter adopted by the Board of Directors (attached as Exhibit E to this
                                                            ---------
     Proxy Statement). The Audit Committee recommends to the Board of Directors,
     subject to stockholder ratification, the selection of the Company's
     independent accountants.

          Management is responsible for the Company's internal controls and the
     financial reporting process. The independent accountants are responsible
     for performing an independent audit of the Company's consolidated financial
     statements in accordance with generally accepted auditing standards and to
     issue a report thereon. The Audit Committee's responsibility is to monitor
     and oversee these processes.

          In this context, the Audit Committee held discussions with management
     and the independent accountants. Management represented to the Audit
     Committee that the Company's consolidated financial statements were
     prepared in accordance with generally accepted accounting principles, and
     the Audit Committee has reviewed and discussed the consolidated financial
     statements with management and the independent accountants. The Audit
     Committee discussed with the independent accountants matters required to be
     discussed by Statement on Auditing Standards No. 61 (Communication with
     Audit Committees).

          The Company's independent accountants also provided to the Audit
     Committee the written disclosures required by Independence Standards Board
     Standard No. 1 (Independence Discussions with Audit Committees), and the
     Audit Committee discussed with the independent accountants the firm's
     independence. Additionally, the Audit Committee has considered whether the
     independent public accountant's provision of "other non-audit services" to
     the Company is compatible with the auditor's independence. The members of
     the Audit Committee are not professionally engaged in the practice of
     auditing or accounting and are not experts in the fields of accounting or
     auditing, including in respect of auditor independence. Members of the
     Audit Committee rely without verification on the information provided to
     them and on the representations made by management and the independent
     auditors.

          Based on the Audit Committee's discussion with management and the
     independent accountants and the Audit Committee's review of the
     representation of management and the report of the independent accountants
     to the Audit Committee, the

                                       23



     Audit Committee recommended that the Board of Directors include the audited
     consolidated financial statements in the Corporation's Annual Report on
     Form 10-K for the fiscal year ended June 30, 2001 filed with the Securities
     and Exchange Commission.

                               SUBMITTED BY THE AUDIT COMMITTEE OF
                               THE BOARD OF DIRECTORS

                               Burton J. Meyer
                               Mark O. Lama

     Compensation Committee Interlocks and Insider Participation

     The current members of the compensation committee are George Myers, Burton
J. Meyer and Charles W. Moore. Mr. Meyer previously served as an officer of IFX
from 1987 to June 1996. On July 1, 1996, IFX sold assets to E.D.& F. Man
International, Inc. Burton J. Meyer, served as Executive Vice President of E.D.&
F. Man International, Inc. from July 1996 to June 30, 2000.

     Mr. Delaney is the Chief Executive Officer, Mr. Moore is a director and Mr.
Lama a principal, of UBS Capital Americas, LLC, an affiliate of UBS Capital
Americas III, L.P. and UBS Capital LLC, which together purchased $25 million of
IFX Preferred Stock in June and July 2000, $15.4 million of IFX Preferred Stock
in May 2001 and $15 million of preferred stock in Tutopia.com, Inc. in August
2000. If approved at the Annual Meeting, UBS will purchase IFX Preferred Stock
in exchange for $7 million and 1.5 million shares of Common Stock currently
owned by UBS. UBS will have the right to put its interest in Tutopia to IFX in
exchange for additional IFX Preferred Stock Mr. Delaney, Mr. Moore and Mr. Lama
have an investment interest in UBS and thus may benefit from transactions
between UBS on the one hand and IFX and its subsidiaries on the other.

                      REPORT OF THE COMPENSATION COMMITTEE
                            ON EXECUTIVE COMPENSATION

     The Compensation Committee of the Board of Director, among other things,
develops and oversee the Company's compensation policy and approve salaries and
annual bonuses for senior management of the Company. The Compensation Committee
currently consists of George Myers, Burton J. Meyer and Charles W. Moore.

     The Company's compensation policy for senior management historically
consisted almost exclusively of cash salaries and, from time to time,
discretionary performance bonuses. In fiscal year 1999, the Board of Directors
implemented a change in the Company's compensation policy to add a significant
long-term equity component to the compensation paid to its senior management.
The Board's goal was to strengthen the Company's ability to recruit, motivate
and retain highly-qualified individuals. The Compensation Committee believes
that stock options and restricted stock, which vest over time and will be
subject to forfeiture, better align the interests of the Company's senior
management with the interests of the Company's stockholders. The Compensation
Committee also believes that substantial equity ownership by

                                       24



individuals in leadership positions within the Company will help to ensure that
such individuals remain focused on building stockholder value.

     In reviewing annual salary, salary increases and equity compensation for
individual executive officers, including the chief executive officer, the
Compensation Committee consider various factors, such as the executive's
contribution to the Company's operating effectiveness and profitability; the
executive's achievement of pre-established goals and performance targets; the
level of responsibility, scope and complexity of such executive's position
relative to other executive management; and the salary levels of other companies
in the same industry.

     IFX's primary business was providing commodity brokerage services until
July 1996 when we sold substantially all of these assets. From July 1996 through
February 1999, IFX's revenues consisted primarily of payments and earnings
related to these discontinued operations. In November 1998, the Company started
its Internet business in Latin America.

Common Stock since the Company's fiscal year ended June 1996 with the cumulative
total return of the Nasdaq Stock Market and the cumulative total return of the
MG Industry Group 850 Internet Service Providers over the same period (assuming
the investment on June 30, 1996 of $100 in each of the Common Stock, the Nasdaq
Stock Market and the MG Industry 850 Internet Service Providers).

years after a "Change of Control", he receives an amount equal to the product of
the number of whole and fractional years remaining until the end of the
employment agreement's term multiplied by three times his annualized current
salary and highest previous annual bonus. The agreement prohibits Mr. Shalom
from disclosing confidential information regarding the Company, and during the
period of his employment with the Company and for one year thereafter being
involved in any capacity with any business competitive with the Company in the
United States, Latin America or in any other market in which the Company is then
conducting business.

     Jose Leiman serves as the Chief Financial Officer of the Company pursuant
to a two-year employment agreement which commenced on May 7, 2001. The term of
the employment agreement is subject to automatic extension unless notified
otherwise by either the Company or Mr. Leiman. Mr. Leiman's base salary is
$235,000 per year for the first year of the agreement and $260,000 per year
thereafter. He received a performance bonus of $250,000 for his service during
the past two years and will receive a minimum bonus of $50,000 per fiscal year
up to a maximum of $125,000 per year. If Mr. Leiman is involuntarily terminated
during the term of the employment agreement (except for "cause"), he receives a
lump sum amount of accrued but unpaid salary and a pro-rata bonus and all of his
options under the 1998 Stock Option Plan immediately vest. He also receives an
amount equal to the product of the number of whole and

                                       27



fractional years remaining until the end of the employment agreement's term
multiplied by his annualized current salary plus bonus for the prior year. If
Mr. Leiman is terminated within two years after a "Change of Control" (as
defined in the employment agreement), he receives an amount equal to the product
of the number of whole and fractional years remaining until the end of the
employment agreement's term multiplied by three times his annualized current
salary and highest previous annual bonus. The agreement prohibits Mr. Leiman
from disclosing confidential information regarding the Company, and during the
period of his employment with the Company and for one year thereafter from being
involved in any capacity with any business competitive with the Company in the
United States, Latin America or in any other market in which the Company is then
conducting business.

     Under the agreements of Messrs. Eidelstein, Shalom and Leiman, a "Change in
                                                                       ---------

succeeding corporation in substantially the same proportions, or which
contemplates that all or substantially all of the business and/or assets of IFX
will be controlled by another corporation; (b) any sale, lease, exchange or
transfer (in one transaction or series of related transactions) of all or
substantially all of the assets of IFX; (c) approval by the stockholders of IFX
of any plan or proposal for the liquidation or dissolution of IFX, unless such
plan or proposal is abandoned within 60 days following such approval; (d) the
acquisition by any "person" (as such term is used in Sections 13(d) and 14(d)(2)
of the Securities Exchange Act of 1934), or two or more Persons acting in
concert, of beneficial ownership (within the meaning of Rule 13d-3 promulgated
under the Exchange Act) of 50% or more of the outstanding shares of voting stock
of IFX; provided, however, that for purposes of the foregoing, "person" excludes
        --------  -------

commencing on the date of this Agreement, those individuals (the "Continuing
                                                                  ----------
Directors") who either (i) were directors of IFX on the first day of each such

period, or (ii) subsequently became directors of IFX and whose actual election
or initial nomination for election subsequent to that date was approved by a
majority of the Continuing Directors then on the board of directors of IFX,
cease to constitute a majority of the board of directors of IFX.

     On June 15, 2001, IFX entered into a Payment and Release Agreement with
Zalman Lekach, the Company's Chief Operating Officer, who voluntarily resigned
from IFX. Under the terms of this Payment and Release Agreement, Mr. Lekach
received a severance payment of $41,236.21 and the right to exercise vested
options in the amount of 263,030 at exercise prices ranging from $8.75 to $20.00
was extended until June 30, 2003. Mr. Lekach released IFX from any claims he may
have against IFX.

(2)  The amounts shown in these columns are the result of calculations at
     assumed annual rates required by the SEC and are not intended to forecast
     possible future appreciation, if any, of the price of the Company's Common
     Stock. The Company did not use an alternative formula for a grant date
     valuation, as the Company is not aware of any formula that will determine
     with reasonable accuracy a present value based on future unknown or
     volatile factors.

             SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

     Section 16(a) of the Exchange Act requires the Company's officers and
directors, and persons who own more than 10% of the Company's Common Stock, to
file with the Securities and Exchange Commission reports of ownership and
changes in ownership and to provide copies of such reports to the Company and to
the Nasdaq Stock Market. Based solely on a review of the copies of such reports
furnished to the Company, or written representations that no reports on Form 5
were required, the Company believes that all officers, directors and 10%
beneficial owners complied with all Section 16(a) filing requirements during
fiscal year 2001.

                              CERTAIN TRANSACTIONS

     Facilito.com IFX owned approximately a 49.9% interest in Facilito, a
company which provides e-commerce solutions. The remaining 50.1% interest in
Facilito is held by The Intcomex Group. The Intcomex Group is owned by family
members of Michael Shalom, IFX's Chief Executive Officer. Facilito is currently
in the process of redeeming the interest held by IFX for aggregate payments
equaling $75,000.

     Yupi Shares. Pursuant to an Amended and Restated Stock Purchase Agreement,
dated as of June 12, 2000, between IFX Online, Inc., a subsidiary of the
Company, and Lee Casty, a then significant stockholder of IFX, IFX Online sold a
part of its shares of Yupi Preferred Stock to Mr. Casty for a total purchase
price of $5 million. The proceeds were used for the Company's working capital.
During August 2001, a subsidiary of Microsoft Corporation acquired Yupi.

                                       30



IFX has received approximately $45,000 with respect to this acquisition, of
which approximately $15,000 is payable to Casty.

     UBS Capital Americas. Mr. Delaney is the Chief Executive Officer, Mr. Moore
is a director and Mr. Lama a principal, of UBS Capital Americas, LLC, an
affiliate of UBS Capital Americas III, L.P. and UBS Capital LLC, which together
purchased $25 million of IFX Preferred Stock in June and July 2000, $15.4
million of IFX Preferred Stock in May 2001 and $15 million of preferred stock in
Tutopia.com, Inc. in August 2000. If approved at the Annual Meeting, UBS will
purchase IFX Preferred Stock in exchange for $7 million and 1.5 million shares
of Common Stock currently owned by UBS. UBS will have the right to put its
interest in Tutopia to IFX in exchange for additional IFX Preferred Stock. Mr.
Delaney, Mr. Moore and Mr. Lama have an investment interest in UBS and thus may
benefit from transactions between UBS on the one hand and IFX and its
subsidiaries on the other.

     Other Tutopia Share Purchases. On August 31, 2000, James Casty, a brother
of Lee S. Casty, a significant stockholder of the Company purchased 53,591
shares of preferred stock of Tutopia. On August 31, 2000, an entity controlled
by Lee Casty, purchased approximately 2,317,500 preferred shares of Tutopia.com,
Inc. in exchange for $4.9 million. The purchase was made pursuant to a private
placement of $20,000,000 of preferred stock of Tutopia.

     Patrick A. Delhougne. In April 2001, the Company engaged Ray & Berndtson to
conduct an executive search for candidates for the Board of Directors of IFX.
The fees for this engagement were $50,000, plus expenses. Mr. Delhougne is a
partner in Ray & Berndtson.

                         DISSENTERS' RIGHTS OF APPRAISAL

     No action was taken in connection with the Proposals by the Board of
Directors or the voting stockholders for which the Delaware General Corporation
  Law, the Company's Certificate of Incorporation, as amended, or the Company's
Bylaws, as amended, provide a right of a stockholder to dissent and obtain
appraisal of or payment for such stockholder's shares.

         INTEREST OF OFFICERS AND DIRECTORS IN MATTERS TO BE ACTED UPON

     Mark Lama and Charles Moore and Charles Delaney are affiliates of UBS and
therefore can benefit indirectly from UBS' investment.

     No other officer or director of the Company has any substantial interest in
the Proposals, except insofar as such officers or directors may be stockholders,
or holders of derivative securities, of the Company, in which case the
implementation of the Proposals will affect them in the same manner as its
affect all other stockholders, or holders of derivative securities, of the
Company.

                         FINANCIAL AND OTHER INFORMATION

         The Company's financial statements are incorporated herein by reference
to the Company's Annual Report on Form 10-K for the fiscal year ended June 30,
2001 (filed with the SEC on October 15, 2001).

                                     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 and Class II Preferred each have a
stated value of Twelve and 31/100 Dollars ($12.31) (the "Stated Value") per
share. The Corporation has also previously authorized 4,418,262 shares of its
Series B Convertible Preferred Stock, par value $1.00 per share, consisting of
4,418,262 shares of Class I Series B Convertible Preferred Stock ("Class I
Series B Preferred") and 424,135 shares of Class II Series B Convertible
Preferred Stock ("Class II Series B Preferred" and, collectively, the "Series B
Convertible Preferred Stock") having the number, powers, preferences and
relative, participating, optional and other rights as set forth in the Amended
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"). The
Corporation has also authorized __________ shares of its Series C Convertible
Preferred Stock, par value $1.00 per share, consisting of ________ shares of
Class I Series C Convertible Preferred Stock ("Class I Series C Preferred") and
_______ shares of Class II Series C Convertible Preferred Stock ("Class II

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 C Certificate"). The Series A Convertible Preferred Stock,
the Series B Convertible Preferred Stock, the Series C Convertible Preferred
Stock and shares of any other class or series of preferred stock of the
Corporation which is convertible, directly or indirectly, into Common Stock,
whether at the time of issuance or upon passage of time or the occurrence of
some future event, are collectively referred to herein as "Convertible Preferred
Stock."

     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

                                       -3-



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
and had all other holders of Convertible Preferred Stock converted such shares
into Common Stock.

               (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

                         (i)  (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 ((x) and
(y), collectively, the "Stated Preference"); plus

                         (ii) an amount equal to such amount per share of Series
A Preferred Stock as would have been payable had each share of Series A
Preferred Stock and all outstanding shares of Convertible Preferred Stock been
converted into Common Stock immediately prior to such bankruptcy, liquidation,
dissolution or winding up of the Corporation after giving effect to the full
payment of the Stated Preference under the preceding paragraph (i) and the
stated preference of the other Convertible Preferred Stock;

provided, that if the amount payable per share of Series A Convertible Preferred
Stock pursuant to the foregoing paragraphs (i) and (ii) exceeds three and
one-half (3-1/2) multiplied by the Stated Preference (the "Maximum Amount"),
each holder of Series A Convertible Preferred Stock shall only be entitled to
receive such Maximum Amount. The sum of the amounts in (i) and (ii) above is
referred to herein as the "Liquidation Preference".

                                       -4-



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 Liquidation Preference, 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 Liquidation Preference 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 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 Capital Americas III, L.P. or UBS Capital LLC (together with any such
Affiliate, "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 B
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 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:

                                       -5-



                                    (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
         Convertible Preferred Stock, voting as a single class.

                                    (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 Convertible Preferred Stock, voting as a single
class.

         4.       VOTING RIGHTS.

                  In addition to any voting rights provided elsewhere herein or
in the Corporation's Certificate of Incorporation, as it may be amended or

class or series of Convertible Preferred Stock, the terms of which expressly
entitle the holder thereof to vote in the election of directors designated by
holders of Convertible Preferred Stock (collectively, "Voting Preferred Stock")
shall have the right to elect four (4) directors, one (1) of which shall be an
Independent Director (as defined below). Such directors shall be elected by the
holders of at least a majority of the voting power of all then outstanding
shares of Voting Preferred Stock, voting as a single class. "Independent
Director" has the meaning specified in Rule 4200(a)(14) of the NASD listing

supplemented, or in any successor rule or regulation.

                                    (ii) Any director elected by the holders of
Voting Preferred Stock shall be referred to herein as a "Preferred Director."
Subject to Section 4(a)(v), the initial term of any director to be appointed
pursuant to Section 4(a)(i) will commence upon his/her election by the holders
of Voting Preferred Stock and shall expire at the first annual meeting of

the initial term of

                                       -6-



such Preferred Director, so long as the Voting Preferred Stock is outstanding,
the holders of such Voting Preferred Stock shall have the right to elect 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 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 Preferred Director elected under Section
4(a)(i) shall serve until such 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 Preferred Director shall be selected as provided in Section 4(a)(i).

                                    (iii) A Preferred Director may be removed
by, and shall not be removed except by, the vote of at least a majority of the
voting power of all then outstanding shares of Voting Preferred Stock, voting as
a single class.

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

                                    (v)   This Section 4(a) shall survive a
Qualified Public Offering (as defined in Section 5(b) below) and until such time
thereafter as less than an aggregate of 25% of the authorized Convertible
Preferred Stock remains outstanding.

[Section 4(a) shall read as follows if certain of the Company's indebtedness has
NOT been restructured in a manner satisfactory to UBS and the Company:

The holders of shares of Series A Preferred Stock shall be entitled to vote in
elections of directors.]

                  (b) Certain Corporate Actions. Until a Qualified Public
Offering or until such time as less than an aggregate of 25% of the authorized
Convertible Preferred Stock remains outstanding, the Corporation shall not, and
shall not permit any of its subsidiaries to, without first obtaining the
affirmative vote or written consent of the holders of at least a majority of the
voting power of all then outstanding shares of Convertible Preferred Stock,
voting as a single class:

                                    (A)   amend, repeal, modify or supplement
         any provision of the Certificate of Incorporation (including any
         certificate of designation forming a part thereof), the Bylaws of the
         Corporation, or any successor certificate of incorporation or bylaws or
         this Amended Certificate of Designation, Number, Powers, Preferences
         and Relative, Participating, Optional and Other Rights of Series A
         Convertible Preferred Stock (the "Certificate of Designation");

         5.    CONVERSION.

               Shares of Series A Convertible Preferred Stock may be converted
into shares of Common Stock, on the terms and conditions set forth in this
Section 5.


                                      -10-



                (a) Optional Conversion.

                                    (i)  At any time and from time to time, each
holder of shares of Series A Preferred Stock may, upon written 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 Preference 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).

                                    (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 Stated Preference 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
Series A Convertible Preferred Stock shall be Three and 00/100 Dollars ($3.00),
subject to adjustment as provided in Section 6 hereof.

                (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 of Series A Preferred Stock 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

                                      -11-



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 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.

                                       -12-



                (f) Reservation of Stock Issuable Upon Conversion. 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, 8,333,332 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 restrictions
thereon, that the Series A Convertible Preferred Stock had immediately prior to
such transaction.

         6.     ADJUSTMENTS.

                The Conversion Price shall be subject to adjustment from time to
time as set forth in this Section 6. The Corporation shall give holders of

Convertible Securities, whether or not the rights to exchange or convert

                                      -16-



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,

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, and

                                      -17-



                          (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 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 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

                                      -18-



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.

                          (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 holders of a majority of the outstanding shares of
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 C Convertible
Preferred Stock, the number of shares of Common Stock or other stock into

                                      -19-



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 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

                                      -20-



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 Second Amended and Restated
Registration Rights Agreement, dated as of ________ __, 2001, among the
Corporation, UBS and certain other stockholders of the Corporation, and such
failure shall continue for a period of 30 days after notice from any such
holder.

                (e) Preferred Stock Purchase Agreement. The Corporation shall
fail to comply with Section 6(f) or 6(g) of the Preferred 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 Preferred 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 Preferred Stock Purchase Agreement shall
prove to have been incorrect or misleading in any substantial material respect
when made.

                (f) There shall have occurred and be continuing a "Triggering
Event" pursuant to the terms of any other class or series of Convertible
Preferred Stock.

                (g) Notwithstanding the foregoing, if a majority of the
[Preferred Directors] 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) [Section 8(b) shall read as follows if certain of the
Company's indebtedness has been restructured in a manner satisfactory to UBS and
the Company:

Upon the occurrence and during the continuance of any Triggering Event, to the
extent the Preferred Directors do not already constitute a majority of the Board
of Directors, 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 "Preferred Directors," would result in such Preferred Directors
constituting a majority of the Board of Directors, and the holders of Voting
Preferred Stock shall be entitled to appoint such newly created directors by
vote of the holders of at least a majority of the voting power of all then
outstanding shares of Voting Preferred Stock, voting as a single class.]

[Section 8(b) shall read as follows if certain of the Corporation's indebtedness
has NOT been restructured in a manner satisfactory to UBS and the Company:

                                      -21-



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 appointed by the
holders of Voting Preferred Stock, would result in such directors constituting a
majority of the Board of Directors, and the holders of Voting Preferred Stock
shall be entitled to appoint such newly created directors by vote of the holders
of at least a majority of the voting power of all then outstanding shares of
Voting Preferred Stock, voting as a single class.]

                (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 Stock may, by notice to the
Corporation, withdraw the repurchase demand contained in the Put Notice.
Notwithstanding the foregoing, the holders of Series A Preferred Stock shall not
be entitled to exercise their repurchase rights hereunder unless the holders of
Convertible Preferred Stock elect to exercise such repurchase rights by vote of
the holders of at least a majority of the voting power of all then outstanding
shares of Convertible Preferred Stock, voting as a single class.

                (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.

                                      -22-



                (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, whether or
not then currently convertible, 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 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, whether or not then
currently convertible, 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, whether or not then currently convertible, 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.

                                      -23-



                (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 Convertible Preferred
Stock, (iv) shares of Class I Series B Preferred Stock issued upon conversion of
Class II Series B Preferred Stock, (v) shares of Class I Series C Preferred
Stock issued upon conversion of Class II Series C Preferred Stock, (vi)
securities issued as consideration for any acquisition approved by a majority of
the Board of Directors (including the affirmative vote of the [Preferred
Directors]), (vii) the Spinway Warrant, (viii) 210,000 shares of Common Stock
upon exercise of the Spinway Warrant, (ix) 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, (x) shares of Common Stock and/or
Convertible Preferred Stock issued pursuant to the Tutopia Put Agreement, or
(xi) 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 that have been
approved in advance by the holders of at least a majority of the voting power of
all then outstanding shares of Convertible Preferred Stock, voting as a single
class.

                (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) 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.

                (d) The Corporation shall have ninety (90) days after expiration
of the twenty (20) 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 shall expire upon
the earlier of (i) the closing of a Qualified Public Offering and (ii) such time
as less than an aggregate of 25% of the authorized Convertible Preferred Stock
remains outstanding.

         10.    RANKING.

                                      -24-



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

         11.    AMENDMENTS.

                This Certificate of Designation may not be amended without first
obtaining the affirmative vote or written consent of the holders of at least a
majority of the voting power of all then outstanding shares of Convertible
Preferred Stock, voting together as a single class, including the affirmative
vote or written consent of the holders of a majority of the shares of Series A
Convertible Preferred Stock.

                      SERIES B CONVERTIBLE PREFERRED STOCK

                The powers, designations, preferences and relative,
participating, optional or other rights of the Series B 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 B
Convertible Preferred Stock" and shall be divided into two classes: Class I
Series B Convertible Preferred Stock ("Class I Series B Preferred Stock") and
Class II Series B Convertible Preferred Stock ("Class B Series B Preferred

Designation filed with the Secretary of State of the State of Delaware on the

$1.00 per share, consisting of _______ shares of Class I Series C Convertible
Preferred Stock ("Class I Series C Preferred") and _______ shares of Class II
Series C Convertible Preferred Stock ("Class II Series C Preferred" and,

         2.     DIVIDENDS.

                (a) Right to Receive Dividends. Holders of Series B 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 B

                                       -2-



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 B
Convertible Preferred Stock into Common Stock and had all other holders of
Convertible Preferred Stock converted such shares into Common Stock.

                  (c) Dividend Preference. Dividends on the Series B 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 B 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 B 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 B 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 B 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
B Convertible Preferred Stock equal to the sum of

                          (i)  (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 ((x) and
(y), collectively, the "Stated Preference"); plus

                          (ii) an amount equal to such amount per share of
Series B Preferred Stock as would have been payable had each share of Series B
Preferred Stock and all outstanding shares of Convertible Preferred Stock been
converted into Common Stock immediately prior to such bankruptcy, liquidation,
dissolution or winding up of the Corporation after giving effect to the full
payment of the Stated Preference under the preceding paragraph (i) and the
stated preference of the other Convertible Preferred Stock;

provided, that if the amount payable per share of Series B Convertible Preferred
Stock pursuant to the foregoing paragraphs (i) and (ii) exceeds three and
one-half (3-1/2) multiplied by the Stated Preference (the "Maximum Amount"),
each holder of Series B Convertible Preferred Stock shall only be entitled to
receive such Maximum Amount. The sum of the amounts in (i) and (ii) above is
referred to herein as the "Liquidation Preference". For purposes of the
foregoing, shares of Class I Series B Preferred Stock issued upon conversion of
the Class II Series B Preferred Stock shall be deemed to have been issued at the
time such shares of Class II Series B Preferred Stock were issued.


                                       -3-



After the payment of the full Liquidation Preference on account of all shares of
Series B 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 B
Convertible Preferred Stock shall be insufficient to permit the payment to the
holders of the full aforesaid Liquidation Preference, then the assets and funds
shall be distributed ratably among holders of Series B Convertible Preferred
Stock in proportion to the number of shares of Series B 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 Liquidation Preference and amounts payable to holders of outstanding
Parity Securities, the holders of Series B 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 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 Capital Americas III, L.P. or UBS Capital LLC (together with any such
Affiliate, "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 B
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 B
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 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:

                                       -4-



                                    (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
         Convertible Preferred Stock, voting as a single class.

                                    (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 Convertible Preferred Stock, voting as a single
class.

          4.    VOTING RIGHTS.

                In addition to any voting rights provided elsewhere herein or in

expressly entitle the holder thereof to vote in the election of directors

term of any director to be appointed pursuant to Section 4(a)(i) will commence
upon his/her election by the holders of Voting Preferred Stock and shall expire

director's earlier removal as provided in Section 4(a)(iii) or death or
resignation and, in the event a vacancy occurs, a replacement Preferred Director
shall be selected as provided in Section 4(a)(i).

                          (iii) A Preferred Director may be removed by, and
shall not be removed except by, the vote of at least a majority of the voting
power of all then outstanding shares of Voting Preferred Stock, voting as a
single class.

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

                          (v)   This Section 4(a) shall survive a Qualified
Public Offering (as defined in Section 5(b) below) and until such time
thereafter as less than an aggregate of 25% of the authorized Convertible
Preferred Stock remains outstanding.

                          (vi)  The holders of shares of Class II Series B

shall not permit any of its subsidiaries to, without first obtaining the
affirmative vote or written consent of the holders of at least a majority of the
voting power of all then outstanding shares of Convertible Preferred Stock,

          (a) Optional Conversion.

                   (i)  At any time and from time to time, each holder of shares
of Class I Series B Preferred Stock may, upon written 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
Preference 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).

                   (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 B Convertible Preferred
Stock shall automatically be converted into such number of shares of Common
Stock as is determined by dividing (x) the Stated Preference 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 B Convertible Preferred Stock shall not be deemed to have converted such
Series B Convertible Preferred Stock until the closing of such offering.

          (c) Conversion Price. The Conversion Price per share for the Series B
Convertible Preferred Stock shall be Three and 00/100 Dollars ($3.00), subject
to adjustment as provided in Section 6 hereof.

                                      -10-



          (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 Class I Series B
Preferred Stock into shares of Common Stock pursuant to Section 5(a) (or, in the
case of an automatic conversion of Class I Series B Preferred Stock and Class II
Series B Preferred Stock 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 B 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 B
Convertible Preferred Stock. At the Corporation's discretion, in the event the
Corporation determines not to issue fractional

                                      -11-



shares, in 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. 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 B Convertible Preferred Stock, 5,154,639 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 B Convertible Preferred Stock without regard to whether the
holders of Series B 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 B 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 B 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 B 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 B
Convertible Preferred Stock, the Series B 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 restrictions thereon, that the
Series B Convertible Preferred Stock had immediately prior to such transaction.

                                      -12-



          (h) Conversion of Class II Series B Preferred Stock.

                   (i)  Beginning on May 3, 2002 each holder of shares of Class
II Series B Preferred Stock may at any time convert all or any portion of such
shares held by such holder into one share of Class I Series B Preferred Stock
for each share of Class II Series B Preferred Stock surrendered for conversion.
The holder of each share of Class II Series B Preferred Stock to be converted
shall surrender the certificate or certificates therefor, duly endorsed for
transfer, at any time during normal business hours, to Payment Office,
accompanied by written notice to the Corporation of such holder's election to
convert. Within 5 Trading Days of such surrender the Corporation will deliver or
cause to be delivered at the Payment Office, certificates representing the
number of shares of Class I Series B Preferred 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.

                   (ii) The Corporation shall reserve and keep available out of
its authorized but unissued shares of Class I Series B Preferred Stock, solely
for the purpose of effecting the conversion of the shares of the Class II Series
B Preferred Stock, 424,135 shares of Class I Series B Preferred Stock. If at any
time the number of authorized but unissued shares of Class I Series B Preferred
Stock shall not be sufficient to effect the conversion of all then outstanding
shares of the Class II Series B Preferred Stock without regard to whether the
holders of Class II Series B 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 Class I
Series B Preferred 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 stockholders, holding stockholders
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 Class II Series B Preferred Stock.

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

               (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

                                      -16-



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,

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, and

                          (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.

                                      -17-



               (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 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 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

                                      -18-



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; Class II Series B Preferred
Stock Adjustments. 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. For the
avoidance of doubt, shares of Class I Series B Preferred Stock issued upon
conversion of Class II Series B Preferred Stock shall be entitled to the same
adjustments to the Conversion Price, the number of shares of Common Stock
issuable upon conversion thereof or otherwise under this Section 6, as if such
shares of Class I Series B Preferred Stock had been issued at the time such
shares of Class II Series B Preferred Stock were issued.

                  (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.

                  (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 B
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 holders of a majority of the outstanding shares of
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 B Convertible
Preferred Stock, the number of shares of Common Stock or other stock into

                                      -19-



which such shares of Series B 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 B 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 B 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 B Convertible Preferred Stock are 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 B 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 B Convertible Preferred
Stock or any prospective purchaser of shares of Series B 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 B 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
B Convertible Preferred Stock without obtaining the requisite approval of the
holders of the Series B Convertible Preferred Stock.

                  (c) Failure to Convert.  The Corporation shall fail for any
reason to issue Common Stock or Class I Series B Preferred Stock, as applicable,
as required under Section 5

                                      -20-



upon the request of any holder of Class I Series B Preferred Stock or Class II
Series B Preferred Stock, as the case may be, 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 B
Convertible Preferred Stock pursuant to the Second Amended and Restated
Registration Rights Agreement, dated as of _______, 2001, among the Corporation,
UBS and certain other stockholders of the Corporation, and such failure shall
continue for a period of 30 days after notice from any such holder.

                  (e) Preferred Stock Purchase Agreement. The Corporation shall
fail to comply with Section 6(f) or 6(g) of the Preferred 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 Preferred 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 Preferred Stock Purchase Agreement shall
prove to have been incorrect or misleading in any substantial material respect
when made.

                  (f) There shall have occurred and be continuing a "Triggering
Event" pursuant to the terms of any other class or series of Convertible
Preferred Stock.

                  (g) Notwithstanding the foregoing, if a majority of the
[Preferred Directors] 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 B 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 B 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 and without regard to whether such shares of Series B Convertible
Preferred Stock are then currently convertible into Common Stock at the option
of the holder).

(b) [Section 8(b) shall read as follows if certain of the Company's indebtedness
has been restructured in a manner satisfactory to UBS and the Company: Upon the
occurrence and during the continuance of any Triggering Event, to the extent the
Preferred Directors do not already constitute a majority of the Board of
Directors, 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 "Preferred Directors," would result in such Preferred Directors
constituting a majority of the Board of Directors, and the holders of Voting
Preferred Stock shall be entitled to appoint such newly created directors by
vote of the holders of

                                      -21-



at least a majority of the voting power of all then outstanding shares of Voting
Preferred Stock, voting as a single class.]

[Section 8(b) shall read as follows if certain of the Company's indebtedness has
NOT been restructured in a manner satisfactory to UBS and the Company:

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 appointed by the
holders of Voting Preferred Stock, would result in such directors constituting a
majority of the Board of Directors, and the holders of Voting Preferred Stock
shall be entitled to appoint such newly created directors by vote of the holders
of at least a majority of the voting power of all then outstanding shares of
Voting Preferred Stock, voting as a single class.]

     (c) Upon the occurrence and during the continuance of any Triggering Event,
any holder of shares of Series B 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 B 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 B Convertible Preferred Stock
specified in the Notice. On the date of any repurchase of shares of Series B
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
B 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 B 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 B Convertible Preferred Stock may, by notice to the Corporation, withdraw
the repurchase demand contained in the Put Notice. Notwithstanding the
foregoing, the holders of Series B Preferred Stock shall not be entitled to
exercise their repurchase rights hereunder unless the holders of Convertible
Preferred Stock elect to exercise such repurchase rights by vote of the holders
of at least a majority of the voting power of all then outstanding shares of
Convertible Preferred Stock, voting as a single class.

     (d) The Corporation stipulates that the remedies at law of each holder of
Series B 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.

                                       -22-



          (e) Any holder of Series B 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 B
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 B Convertible Preferred Stock or Common
Stock issued upon conversion of Series B 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 B Convertible Preferred Stock or Common Stock issued upon conversion
of Series B 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 B Convertible Preferred Stock, whether or not then currently
convertible, 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 B Convertible Preferred Stock or Common Stock issued upon conversion
of Series B 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 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 B
Convertible Preferred Stock, whether or not then currently convertible, 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 B Convertible Preferred Stock or Common Stock issued upon
conversion of Series B Convertible Preferred Stock (including all shares
issuable upon conversion of the Series B Convertible Preferred Stock, whether or
not then currently convertible, 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 B Convertible Preferred Stock or Common

                                       -23-



Stock issued upon conversion of Series B 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 Convertible Preferred Stock, (iv) shares of
Class I Series B Preferred Stock issued upon conversion of Class II Series B
Preferred Stock, (v) shares of Class I Series C Preferred Stock issued upon
conversion of Class II Series C Preferred Stock, (vi) securities issued as
consideration for any acquisition approved by a majority of the Board of
Directors (including the affirmative vote of the [Preferred Directors]), (vii)
the Spinway Warrant, (viii) 210,000 shares of Common Stock upon exercise of the
Spinway Warrant, (ix) 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, (x) shares of Common Stock and/or Convertible Preferred
Stock issued pursuant to the Tutopia Put Agreement, or (xi) 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 that have been approved in
advance by the holders of at least a majority of the voting power of all then
outstanding shares of Convertible Preferred Stock, voting as a single class.

     (c) In the event the Corporation proposes to undertake an issuance of New
Securities, it shall give each holder of Series B Convertible Preferred Stock or
Common Stock issued upon conversion of Series B 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) 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.

     (d) The Corporation shall have ninety (90) days after expiration of the
twenty (20) 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 B Convertible Preferred
Stock or Common Stock issued upon conversion of Series B Convertible Preferred
Stock in the manner provided above.

                                       -24-



          (e) The rights granted under this Section 9 shall expire upon the
earlier of (i) the closing of a Qualified Public Offering and (ii) such
time as less than an aggregate of 25% of the authorized Convertible
Preferred Stock remains outstanding.

     10.  RANKING.

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

     11.  AMENDMENTS.

          This Certificate of Designation may not be amended without first
obtaining the affirmative vote or written consent of the holders of at
least a majority of the voting power of all then outstanding shares of
Convertible Preferred Stock, voting together as a single class, including
the affirmative vote or written consent of the holders of a majority of the
shares of Series B Convertible Preferred Stock.

                      SERIES C CONVERTIBLE PREFERRED STOCK

         The powers, designations, preferences and relative, participating,
optional or other rights of the Series C 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 C
Convertible Preferred Stock" and shall be divided into two classes: Class I
Series C Convertible Preferred Stock ("Class I Series C Preferred Stock") and
Class II Series C Convertible Preferred Stock ("Class II Series C Preferred
Stock", and together with the Class I Series C Preferred Stock, the "Series C
Convertible Preferred Stock"). The Series C Convertible Preferred Stock shall
have $1.00 par value per share. The number of authorized shares of the Class I
Series C Convertible Preferred Stock shall be ________ shares. The number of
authorized shares of the Class II Series C Preferred Stock shall be ________
shares. Shares of the Series C Convertible Preferred Stock shall have a stated
value of Three and 00/100 Dollars ($3.00) per share (the "Stated Value"). The
Corporation has previously authorized (i) 2,030,869 shares of its Series A
Convertible Preferred Stock, par value $1.00 per share (the "Series A
Convertible Preferred Stock") having the number, powers, preferences and
relative, participating, optional and other rights as set forth in the Amended
Certificate of Designation filed with the Secretary of State of the State of
Delaware on the date of the filing hereof (the "Series A Certificate") and (ii)
4,418,262 shares of its Series B Convertible Preferred Stock, par value $1.00
per share, consisting of 3,994,127 shares of Class I Series B Convertible
Preferred Stock ("Class I Series B Preferred") and 424,135 shares of Class II
Series B Convertible Preferred Stock ("Class II Series B Preferred" and,
collectively, the "Series B Convertible Preferred Stock") having the number,
powers, preferences and relative, participating, optional and other rights as
set forth in the Amended Certificate of Designation filed with the Secretary of
State of the State of Delaware on the date of the filing hereof (the "Series B

Convertible Preferred Stock, the Series C Convertible Preferred Stock and shares
of any other class or series of preferred stock of the Corporation which is
convertible, directly or indirectly, into Common Stock, whether at the time of
issuance or upon passage of time or the occurrence of some future event, are
collectively referred to herein as "Convertible Preferred Stock."

     2.  DIVIDENDS.

         (a) Right to Receive Dividends. Holders of Series C 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 C

                                       -2-



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 C
Convertible Preferred Stock into Common Stock and had all other holders of
Convertible Preferred Stock converted such shares into Common Stock.

         (c) Dividend Preference. Dividends on the Series C 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 C 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 C 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 C 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 C
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 C Convertible
Preferred Stock equal to the sum of

             (i)  (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 ((x) and
(y), collectively, the "Stated Preference"); plus

             (ii) an amount equal to such amount per share of Series C Preferred
Stock as would have been payable had each share of Series C Preferred Stock and
all outstanding shares of Convertible Preferred Stock been converted into Common
Stock immediately prior to such bankruptcy, liquidation, dissolution or winding
up of the Corporation after giving effect to the full payment of the Stated
Preference under the preceding paragraph (i) and the stated preference of the
other Convertible Preferred Stock;

provided, that if the amount payable per share of Series C Convertible Preferred
Stock pursuant to the foregoing paragraphs (i) and (ii) exceeds three and
one-half (3-1/2) multiplied by the Stated Preference (the "Maximum Amount"),
each holder of Series C Convertible Preferred Stock shall only be entitled to
receive such Maximum Amount. The sum of the amounts in (i) and (ii) above is
referred to herein as the "Liquidation Preference". For purposes of the
foregoing, shares of Class I Series C Preferred Stock issued upon conversion of
the Class II Series C Preferred Stock shall be deemed to have been issued at the
time such shares of Class II Series C Preferred Stock were issued.

                                       -3-



After the payment of the full Liquidation Preference on account of all shares of
Series C 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 C
Convertible Preferred Stock shall be insufficient to permit the payment to the
holders of the full aforesaid Liquidation Preference, then the assets and funds
shall be distributed ratably among holders of Series C Convertible Preferred
Stock in proportion to the number of shares of Series C 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 Liquidation Preference and amounts payable to holders of outstanding
Parity Securities, the holders of Series C 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 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 Capital Americas III, L.P. or UBS Capital LLC (together with any such
Affiliate, "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 C
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 C
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 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:

                                      -4-



                         (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 Convertible Preferred Stock,
         voting as a single class.

                         (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 Convertible Preferred Stock, voting as a single class.

         4.  VOTING RIGHTS.

             In addition to any voting rights provided elsewhere herein or in

                         (i) Subject to the terms hereof, the holders of the
Class I Series C Preferred Stock, together with the holders of any other class
or series of Convertible Preferred Stock, the terms of which expressly entitle
the holder thereof to vote in the election of directors designated by holders of
Convertible Preferred Stock (collectively, "Voting Preferred Stock") shall have
the right to elect four (4) directors, one (1) of which shall be an Independent
Director (as defined below). Such directors shall be elected by the holders of
at least a majority of the voting power of all then outstanding shares of Voting
Preferred Stock, voting as a single class. "Independent Director" has the
meaning specified in Rule 4200(a)(14) of the NASD listing standards, as in
effect on the date hereof and as the same may be amended or supplemented, or in
any successor rule or regulation.

                         (ii) Any director elected by the holders of Voting
Preferred Stock shall be referred to herein as a "Preferred Director." Subject
to Section 4(a)(v), the initial


                                       -5-



term of any director to be appointed pursuant to Section 4(a)(i) will commence
upon his/her election by the holders of Voting 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 Preferred Director, so
long as the Voting Preferred Stock is outstanding, the holders of such Voting
Preferred Stock shall have the right to elect 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 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 Preferred Director elected under Section 4(a)(i) shall serve until
such 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 Preferred Director
shall be selected as provided in Section 4(a)(i).

                         (iii) A Preferred Director may be removed by, and shall
not be removed except by, the vote of at least a majority of the voting power of
all then outstanding shares of Voting Preferred Stock, voting as a single class.

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

                         (v)   This Section 4(a) shall survive a Qualified
Public Offering (as defined in Section 5(b) below) and until such time
thereafter as less than an aggregate of 25% of the authorized Convertible
Preferred Stock remains outstanding.

                         (vi)  The holders of shares of Class II Series C
Preferred Stock shall not be entitled to vote in elections of directors.]

             [Section 4(a) shall read as follows if certain of the Company's
indebtedness to Lucent has NOT been restructured in a manner satisfactory to UBS
and the Company:

The holders of shares of Class I Series C Preferred Stock shall be entitled to
vote in elections of directors. The holders of shares of Class II Series C
Preferred Stock shall not be entitled to vote in elections of directors.]

             (b) Certain Corporate Actions. Until a Qualified Public Offering or
until such time as less than an aggregate of 25% of the authorized Convertible
Preferred Stock remains outstanding, the Corporation shall not, and shall not
permit any of its subsidiaries to, without first obtaining the affirmative vote
or written consent of the holders of at least a majority of the voting power of
all then outstanding shares of Convertible Preferred Stock, voting as a single
class:

                         (A)   amend, repeal, modify or supplement any provision
         of the Certificate of Incorporation (including any certificate of

         greater of (1) the Stated Value (as adjusted for stock splits,

              Shares of Series C Convertible Preferred Stock may be converted
into shares of Common Stock, on the terms and conditions set forth in this
Section 5.

              (a) Optional Conversion.

                         (i) At any time and from time to time, each holder of
shares of Class I Series C Preferred Stock may, upon written 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 Preference 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).

                         (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 C Convertible
Preferred Stock shall automatically be converted into such number of shares of
Common Stock as is determined by dividing (x) the Stated Preference 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 C Convertible Preferred Stock shall not be deemed to have converted such
Series C Convertible Preferred Stock until the closing of such offering.

              (c) Conversion Price. The Conversion Price per share for the
Series C Convertible Preferred Stock shall be Three and 00/100 Dollars ($3.00),
subject to adjustment as provided in Section 6 hereof.

                                      -10-



              (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 Class I Series C
Preferred Stock into shares of Common Stock pursuant to Section 5(a) (or, in the
case of an automatic conversion of Class I Series C Preferred Stock and Class II
Series C Preferred Stock 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 C 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 C
Convertible Preferred Stock. At the Corporation's discretion, in the event the
Corporation determines not to issue fractional

                                       -11-



shares, in 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

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 C Convertible Preferred Stock, ________ 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 C Convertible Preferred Stock without regard to whether the holders of
Series C 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 C 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 C 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 C 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 C Convertible Preferred Stock, the Series C 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 restrictions
thereon, that the Series C Convertible Preferred Stock had immediately prior to
such transaction.

share of Class II Series C Preferred Stock to be converted shall surrender the
certificate or certificates therefor, duly endorsed for transfer, at any time

Payment Office, certificates representing the number of shares of Class I Series
C Preferred 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.

                    (ii)  The Corporation shall reserve and keep available out
of its authorized but unissued shares of Class I Series C Preferred Stock,
solely for the purpose of effecting the conversion of the shares of the Class II
Series C Preferred Stock, __________ shares of Class I Series C Preferred Stock.
If at any time the number of authorized but unissued shares of Class I Series C
Preferred Stock shall not be sufficient to effect the conversion of all then
outstanding shares of the Class II Series C Preferred Stock without regard to
whether the holders of Class II Series C 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
Class I Series C Preferred 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 stockholders, holding stockholders
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

          (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 conversion or exchange of such Convertible Securities.

          (e)  Issuance of Convertible Securities. Except with respect to

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

                                      -16-



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,

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, and

                    (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.

                                      -17-



          (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 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
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

                                      -18-



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; Class II Series C
Preferred Stock Adjustments. 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. For the
avoidance of doubt, shares of Class I Series C Preferred Stock issued upon
conversion of Class II Series C Preferred Stock shall be entitled to the same
adjustments to the Conversion Price, the number of shares of Common Stock
issuable upon conversion thereof or otherwise under this Section 6, as if such
shares of Class I Series C Preferred Stock had been issued at the time such
shares of Class II Series C Preferred Stock were issued.

                    (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.

                    (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 C
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 holders of a majority of the outstanding shares of
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 C Convertible
Preferred Stock, the number of shares of Common Stock or other stock into

                                      -19-



which such shares of Series C 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 C 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 C 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 C Convertible Preferred
Stock are 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 C 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 C Convertible Preferred Stock or any
prospective purchaser of shares of Series C Convertible Preferred Stock
designated by such holders.

     7.   TRIGGERING EVENTS.

Event" for purposes hereof:

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

          (g)  Notwithstanding the foregoing, if a majority of the [Preferred
Directors] 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 C 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 C 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 and without regard to whether such shares of Series C Convertible Preferred
Stock are then currently convertible into Common Stock at the option of the
holder).

          (b)  [Section 8(b) shall read as follows if certain of the Company's
indebtedness has been restructured in a manner satisfactory to UBS and the
Company:

Upon the occurrence and during the continuance of any Triggering Event, to the
extent the Preferred Directors do not already constitute a majority of the Board
of Directors, 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 "Preferred Directors," would result in such Preferred Directors
constituting a majority of the Board of Directors, and the holders of Voting
Preferred Stock shall be entitled to appoint such newly created directors by
vote of the holders of

                                      -21-



at least a majority of the voting power of all then outstanding shares of Voting
Preferred Stock, voting as a single class.]

[Section 8(b) shall read as follows if certain of the Company's indebtedness has
NOT been restructured in a manner satisfactory to UBS and the Company:

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 appointed by the
holders of Voting Preferred Stock, would result in such directors constituting a
majority of the Board of Directors, and the holders of Voting Preferred Stock
shall be entitled to appoint such newly created directors by vote of the holders
of at least a majority of the voting power of all then outstanding shares of
Voting Preferred Stock, voting as a single class.]

          (c)  Upon the occurrence and during the continuance of any Triggering
Event, any holder of shares of Series C 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 C 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 C Convertible
Preferred Stock specified in the Notice. On the date of any repurchase of shares
of Series C 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 C 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 C 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 C Convertible Preferred Stock may, by notice to the
Corporation, withdraw the repurchase demand contained in the Put Notice.
Notwithstanding the foregoing, the holders of Series C Preferred Stock shall not
be entitled to exercise their repurchase rights hereunder unless the holders of
Convertible Preferred Stock elect to exercise such repurchase rights by vote of
the holders of at least a majority of the voting power of all then outstanding
shares of Convertible Preferred Stock, voting as a single class.

          (d)  The Corporation stipulates that the remedies at law of each
holder of Series C 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.

                                      -22-



          (e)  Any holder of Series C 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 C
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 C Convertible Preferred Stock or Common
Stock issued upon conversion of Series C 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 C Convertible Preferred Stock or Common Stock issued upon conversion
of Series C 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 C Convertible Preferred Stock, whether or not then currently
convertible, 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 C Convertible Preferred Stock or Common Stock issued upon conversion
of Series C 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 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 C
Convertible Preferred Stock, whether or not then currently convertible, 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 C Convertible Preferred Stock or Common Stock issued upon
conversion of Series C Convertible Preferred Stock (including all shares
issuable upon conversion of the Series C Convertible Preferred Stock, whether or
not then currently convertible, 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 C Convertible Preferred Stock or Common

                                      -23-



Stock issued upon conversion of Series C 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 Convertible Preferred
Stock, (iv) shares of Class I Series B Preferred Stock issued upon conversion of
Class II Series B Preferred Stock, (v) shares of Class I Series C Preferred
Stock issued upon conversion of Class II Series C Preferred Stock, (vi)
securities issued as consideration for any acquisition approved by a majority of
the Board of Directors (including the affirmative vote of the [Preferred
Directors]), (vii) the Spinway Warrant, (viii) 210,000 shares of Common Stock
upon exercise of the Spinway Warrant, (ix) 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, (x) shares of Common Stock and/or
Convertible Preferred Stock issued pursuant to the Tutopia Put Agreement, or
(xi) 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 that have been
approved in advance by the holders of at least a majority of the voting power of
all then outstanding shares of Convertible Preferred Stock, voting as a single
class.

          (c)  In the event the Corporation proposes to undertake an issuance of
New Securities, it shall give each holder of Series C Convertible Preferred
Stock or Common Stock issued upon conversion of Series C 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) 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.

          (d)  The Corporation shall have ninety (90) days after expiration of
the twenty (20) 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 C Convertible Preferred
Stock or Common Stock issued upon conversion of Series C Convertible Preferred
Stock in the manner provided above.

                                      -24-



          (e)  The rights granted under this Section 9 shall expire upon the
earlier of (i) the closing of a Qualified Public Offering and (ii) such time as
less than an aggregate of 25% of the authorized Convertible Preferred Stock
remains outstanding.

     10.  RANKING.

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

     11.  AMENDMENTS.

          This Certificate of Designation may not be amended without first
obtaining the affirmative vote or written consent of the holders of at least a
majority of the voting power of all then outstanding shares of Convertible
Preferred Stock, voting together as a single class, including the affirmative
vote or written consent of the holders of a majority of the shares of Series C
Convertible Preferred Stock.

                                                                       ---------

I.   Purpose
     -------

     The primary function of the Audit Committee (the "Committee") of the Board
of Directors of IFX Corporation (the "Corporation") is to assist the Board of
Directors in fulfilling its oversight responsibilities by:

     .         Serving as an independent and objective party to monitor the
Corporation's financial reporting processes and internal control systems;

     .         Reviewing and appraising the audit efforts of the Corporation's
independent accountants and internal auditors; and

     .         Providing an open avenue of communication among the Corporation's

Board of Directors.

The Committee will primarily fulfill these responsibilities by carrying out the
activities enumerated in Section III of this Charter.

II.  Composition
     -----------

     The Committee shall be comprised of three or more directors as determined
by the Board, each of whom shall be independent directors, and free from any
relationship that, in the opinion of the Board, would interfere with the
exercise of his or her independent judgment as a member of the Committee. All
members of the Committee shall have a working familiarity with basic finance and
accounting practices, and at least one member of the Committee shall have
accounting or related financial management expertise.

III. Responsibilities and Duties
     ---------------------------

     To fulfill its responsibilities and duties, the Audit Committee will:

          1.   Hold such regular meetings as may be necessary and such special
               meetings as may be called by the Chairman of the Committee or at
               the request of the independent accountants;

          2.   Review and update, as necessary, the Committee's Charter
               annually;

          4.   Recommend to the Board of Directors the independent accountants
               to be nominated, approve the compensation of the independent

               independent accountants;

          5.   Review and concur in the appointment, replacement, reassignment,
               or dismissal of the director of internal auditing;

               the independent accountants, including a review of management
               consulting services and related fees provided by the independent
               accountants;

          7.   Meet with the independent accountants and financial management to
               review the scope of the proposed audit for the current year and

               annual audit, review with the independent accountants and
               financial management:

                      are to be communicated to the Committee under generally
                      accepted auditing standards.

          8.   Review with the independent accountants, the internal auditors
               and financial and accounting personnel the adequacy and

               such controls.

          9.   Discuss with the independent accountants and financial management
               their qualitative judgments about the appropriateness, not just
               the acceptability, of accounting principles and financial

               aggressiveness or conservatism of such practices;

          10.  Review the internal audit function of the Corporation, including

               independent accountants to meet with the Committee without
               members of management present to discuss any matters that the
               Committee or these groups believe should be discussed privately;

          13.  Review accounting and financial human resources and succession
               planning within the Corporation;

          14.  Conduct or authorize investigations into any matters within the

               any such investigation;

          15.  Report through its Chairman to the Board of Directors following
               the meetings of the Audit Committee; and

          16.  Maintain minutes or other records of meetings of the Audit
