                        ANNUAL MEETING OF STOCKHOLDERS

                               December 7, 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 26, 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.

   IFX, Lee S. Casty ("Casty"), Joel M. Eidelstein ("Eidelstein"),
International Technology Investments, LC ("ITI"), Michael Shalom ("Shalom"),
and UBS Capital Americas III, L.P. and UBS Capital LLC (together with UBS
Capital Americas III, L.P., "UBS") have entered into a Second Amended and
Restated Stockholders' Agreement (the "Current Stockholders' Agreement") dated
as of May 7, 2001. Under the Current Stockholders' Agreement, Casty,
Eidelstein, ITI, Shalom and UBS have agreed to vote their shares to elect to
the Board of Directors three persons nominated by UBS (currently, Mark Lama,
Charles Delaney and Charles Moore); one person nominated by ITI (currently,
Michael Shalom); one person nominated by Lee S. Casty (currently, Joel M.
Eidelstein); one person nominated jointly by Mr. Eidelstein and ITI (currently,
George Myers); and two other independent directors (currently, Burton Meyer and
Patrick Delhougne). 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

                                      2



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).

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.

   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 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 $3,000,000 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
shares of Common Stock, and the 3,833,333 shares of

                                      5



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 17,321,557 votes (or approximately 57.6%) 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
22,931,557 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).

                                 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.

                                      6



   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 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
110%. UBS would hold approximately 17.3 million shares, or approximately 58%,
of these shares.

                                      7



   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.

      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 2.3356 votes. 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

          approve the annual budget of the Company;

                                      8



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

          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.

   Although this Proxy Statement contains a summary of the Series C Preferred
Stock, this summary is not intended to be complete and reference should be made
to Exhibit B to this Proxy Statement for the complete text of the form of the
Series C Preferred Stock Certificate of Designation.

Vote Required

   The proposal to issue the New Stock 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 vote for the issuance of the New Stock.
Accordingly, the proposal will be approved at the Annual Meeting.

Recommendation of the Board of Directors

   The Board of Directors of the Company unanimously recommends that the
stockholders vote FOR the issuance of the New Stock.

                                      9

Changes to Reflect Issuance of Series C Preferred Stock

   Upon issuance of the Series C Preferred Stock, certain material terms of the
Series A Preferred Stock and Series B Preferred Stock with respect to rank,
liquidation preference (including the addition of a participating preference),
voting rights, conversion rate and adjustments to conversion rate will change
as follows:

          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. 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 have been
       paid if each share of the Series A 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.

                                      11



          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 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 A Preferred Stock and
       Series B Preferred Stock as a liquidation preference cannot exceed three
       and one-half (3-1/2) multiplied by the applicable Stated Preference.

          Voting Rights. Each share of Series A Preferred Stock will be
       entitled to one vote and each share of Series B Preferred Stock will be
       entitled to 1.4344 votes. The holders of the Series A Preferred Stock,
       the Series B Preferred Stock and the Series C Preferred Stock are

as a single class.

   Under the terms of the Voting Agreement, the holders of all of the Preferred

                             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 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.

                                      13



   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
this occurs, George Myers has agreed to resign from the Board. If the Company

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

                                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.

                                      15



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.

   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

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.

   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.

                                      16



   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 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.

                                      17



   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 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

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

with this transaction), $15 million of preferred stock in Tutopia.com, Inc. in

        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 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.


                                          SUBMITTED BY THE COMPENSATION
                                          COMMITTEE OF THE BOARD OF

         COMPARISON OF CUMULATIVE TOTAL RETURN AMONG IFX CORPORATION,
               THE NASDAQ STOCK MARKET INDEX AND INDUSTRY INDEX

   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.

   The graph below compares the cumulative total shareholder return on the
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).

    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 owns 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 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. IFX
has received approximately $46,000 with respect to this acquisition, of which
approximately $16,000 is payable to Casty.

   UBS Capital Americas. Mr. Delaney is the President, Mr. Moore is a partner
and Mr. Lama a principal, of UBS Capital Americas, LLC, an affiliate of UBS

million of IFX Preferred Stock in June and July 2000 (UBS received a $750,000
private equity fee in connection with this transaction), $15.4 million of IFX
Preferred Stock in May 2001 (UBS received a $462,000 private equity fee in
connection with this transaction), $15 million of preferred stock in
Tutopia.com, Inc. in August 2000 and $1.83 million of Tutopia stock in 2001. 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.

                                      24

                        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

                     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
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 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 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

                                      B-2



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.

   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

                                      B-3



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:

          (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 restated
from time to time (the "Certificate of Incorporation"), and any voting rights
provided by law, the holders of shares of Series C Convertible Preferred Stock
shall have the following voting rights:

   (a) Election of Directors.

   [Section 4(a) shall read as follows if certain of the Company's indebtedness
has been restructured in a manner satisfactory to UBS and the Company:

      (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

                                      B-4



   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 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 designation forming a part
   thereof), the Bylaws of the Corporation, or any successor certificate of
   incorporation or bylaws or this Certificate of Designation, Number, Powers,
   Preferences and Relative, Participating, Optional and Other Rights of Series
   C Convertible Preferred Stock (the "Certificate of Designation");

      (B) authorize or permit the Corporation or any subsidiary of the
   Corporation to issue any capital stock or any options, warrants or other
   rights exchangeable or exercisable therefor, other than (i) shares of Series

5. CONVERSION.

   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.

   (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

                                      B-8



   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 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 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.


                                      B-9



      (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.

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

      (i) Beginning on the first anniversary of the date of filing of this
   Certificate, each holder of shares of Class II Series C 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 C Preferred Stock for each share of Class
   II Series C Preferred Stock surrendered for conversion. The holder of each
   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 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 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 effecting the conversion of the
   shares of the Class II Series C Preferred Stock.

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.

                                     B-13



   (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 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.

                                     B-14



      (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 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.

                                     B-15



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 C 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
   C Convertible Preferred Stock without obtaining the requisite approval of
   the holders of the Series C Convertible Preferred Stock.

      (c) Failure to Convert. The Corporation shall fail for any reason to
   issue Common Stock or Class I Series C Preferred Stock, as applicable, as
   required under Section 5 upon the request of any holder of Class I Series C
   Preferred Stock or Class II Series C 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 C
   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 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

                                     B-16



   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 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.

   (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.

                                     B-17



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 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.

                                     B-18



   (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.

   (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.

                     SERIES A CONVERTIBLE PREFERRED STOCK

   The powers, designations, preferences and relative, participating, optional

1.  DESIGNATION AND AMOUNT.

   This series of preferred stock shall be designated as "Series A Convertible

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

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

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 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

                                      C-2



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".

   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

                                      C-3



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:

          (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 restated
from time to time (the "Certificate of Incorporation"), and any voting rights
provided by law, the holders of shares of Series A Convertible Preferred Stock
shall have the following voting rights:

   (a) Election of Directors.

      (i) Subject to the terms hereof, the holders of the Series A Preferred
   Stock, together with the holders of any other class or series 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

   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

   (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

   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

   (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 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

                                      C-8



   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.

   (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

                                      C-9



   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.

   number of shares of Common Stock,

then the applicable Conversion Price immediately after the occurrence of any

immediately prior to the occurrence of such event and (B) a fraction, the
numerator of which shall be the number of Fully Diluted Outstanding shares of
Common Stock immediately prior to the occurrence of such event and the

                                     C-11



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

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

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

                                     C-12



   (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.

   (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

                                     C-13



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

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

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

      (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 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.

                                     C-14



   (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 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.

                                     C-15



      (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:

      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.

                                     C-16



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

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

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

9. PREEMPTIVE RIGHT.

   (a) Each holder of Series A Convertible Preferred Stock or Common Stock
issued upon conversion of Series A Convertible Preferred Stock, shall have a
right of first refusal (the "Preemptive Right") to purchase its pro rata share,
based on such holder's percentage ownership interest in the Corporation, of New
Securities (as defined below) which the Corporation, from time to time,
proposes to sell and issue (subject to such requirements and restrictions
imposed by the Securities Act of 1933, as amended, and state securities laws
and to the actual issuance of the New Securities). The pro rata shares of any
holder of Series A Convertible Preferred Stock or Common Stock issued upon
conversion of Series A Convertible Preferred Stock, for purposes of this
Preemptive Right, shall be the ratio of (i) the number of shares of Common
Stock owned, of record or beneficially, by such holder (including all shares
issuable upon conversion of the Series A Convertible Preferred Stock, 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.

   (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

                                     C-17



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.

   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.

                                          Title: President

                                          ATTEST:

                                          Title:

                                    ANNEX A

                     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 Stock", and
together with the Class I Series B Preferred Stock, the "Series B Convertible
Preferred Stock"). The Series B Convertible Preferred Stock shall have $1.00
par value per share. The number of authorized shares of the Class I Series B
Preferred Stock shall be 4,418,262 shares. The number of authorized shares of
the Class II Series B Preferred Stock shall be 424,135 shares. Shares of the
Series B Convertible Preferred Stock shall have a stated value of Three and
50/100 Dollars ($3.50) per share (the "Stated Value"). The Corporation has
previously authorized and issued 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 Second 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"). 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 Series C Preferred" and,
collectively, the "Series C Convertible Preferred Stock") having the number,
powers, preferences and relative, participating, optional and other rights as
set forth in the Certificate of Designation filed with the Secretary of State
of the State of Delaware on the date of the filing hereof (the "Series 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 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 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

                                      D-2



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.

   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

                                      D-3



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:

          (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 restated
from time to time (the "Certificate of Incorporation"), and any voting rights
provided by law, the holders of shares of Series B Convertible Preferred Stock
shall have the following voting rights:

   (a) Election of Directors.

   [Section 4(a) shall read as follows if certain of the Company's indebtedness
has been restructured in a manner satisfactory to UBS and the Company:

      (i) Subject to the terms hereof, the holders of the Class I Series B
   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

                                      D-4



   (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 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 B 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
has NOT been restructured in a manner satisfactory to UBS and the Company:

      The holders of shares of Class I Series B Preferred Stock shall be
   entitled to vote in elections of directors. The holders of shares of Class
   II Series B 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 designation forming a part
   thereof), the Bylaws of the Corporation, or any successor certificate of

   (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.

   (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

                                      D-8



   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 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.

                                      D-9



   (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.

   (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.

have been issued and outstanding, (ii) the price per share for such Additional
Shares of Common Stock shall be deemed to be the lowest price per share at
which such Additional Shares of Common Stock are issuable to such holders, and
(iii) the Corporation shall have received all of the consideration, if any,
payable for such warrants or other rights as of the date of the actual issuance
thereof. No further adjustments of the Conversion Price shall be made upon the
actual issue of such Common Stock or of such Convertible Securities upon
exercise of such warrants or other rights or upon the actual issue of such
Common Stock upon such conversion or exchange of such Convertible Securities.

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

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

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

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

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

                                     D-13



   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.

   (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 satisfaction of any
   dividends upon any class of stock other than Common Stock, the Corporation

                                     D-14



   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 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

                                     D-15



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 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).

                                     D-16



   (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 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.

   (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

                                     D-17



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 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

                                     D-18



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.

   (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.

                                                                      Exhibit E
