2.   Put Option.
     ----------

     (a) From and after the date hereof until the first (1st) anniversary of the
date hereof (the "Expiration Date"), UBS shall have the right from time to time,
upon written notice thereof, specifying the Tutopia Shares to be put (the "UBS
Put Notice"), to put to the Company all or any portion of its Tutopia Shares
(the "Put Option") at a price per share equal to the Exchange Ratio.

     (b) Within ten (10) days after each receipt of a UBS Put Notice, the
Company shall promptly make an offer to all other holders of Tutopia Shares who
are parties to the Tutopia Stockholders Agreement (except Latin Guide, Inc.), by
written notice thereof, to purchase a Pro Rata Portion of the Tutopia Shares
held by each such holder thereof at a price per share equal to the Exchange
Ratio and on the other terms and conditions set forth herein.  UBS and all such
other holders of Tutopia Shares who deliver a put notice (collectively with the
UBS Put Notice, the "Put Notices") to the Company within fifteen (15) days after
receipt of a notice from the Company pursuant to this Section 2(b), shall be
considered to have exercised the Put Option simultaneously as of the date the
Company received the UBS Put Notice for purposes of this Agreement.

     (c) Within thirty (30) days following the date of a UBS Put Notice, the
Company shall purchase or cause one or more of its subsidiaries to purchase and
each Seller (as defined below) shall sell to the Company the Tutopia Shares put
pursuant to the Put Notices (subject to the Sellers' complying with any rights
of first refusal or other restrictions on transfer of such Tutopia Shares).

     (d) At the closing of a purchase of Tutopia Shares pursuant this Agreement
(a "Closing"), UBS and each of the other holders of Tutopia Shares which

UBS, the "Sellers") shall deliver the certificate or certificates representing
the Tutopia Shares owned by such Seller to be sold to the Company, free and
clear of all liens and encumbrances (other than pursuant to the Tutopia
Stockholders Agreement), and the Company, as payment therefor, will issue and
deliver to such Seller the appropriate number of shares of IFX Preferred Stock
or IFX Common Stock, as the case may be, in the form of a single certificate (or
such greater number of certificates representing such shares as such Seller may
request), each dated the date of Closing and registered in such Seller's name
(or in the name of such Seller's nominee(s)).  Each Seller which is to be issued
shares of IFX Preferred Stock as payment for its Tutopia Shares shall be issued
such shares of IFX Preferred Stock in such proportions between shares of voting

     (e) At each Closing, each Seller which is not then a party to the
Stockholders Agreement or the Registration Rights Agreement (as such terms are
defined in the Preferred

                                      -2-
<PAGE>

Stock Purchase Agreement) shall become a party to each such agreement by
executing and delivering to the Company a counterpart signature page thereof. In
addition, at each Closing, each Seller shall represent and warrant to the
Company that it is acquiring the shares of IFX Preferred Stock or IFX Common
Stock, as the case may be, for its own account, for investment purposes only,
and with no present intention of distributing, selling or otherwise disposing of
them, and each other holder of Tutopia Shares shall waive any further rights
under the Tutopia Stockholders Agreement as a condition to participating in the
Put Option. In the event that any Seller refuses or fails to become a party to
such agreements or make such representation and warranty or otherwise fails to
comply with all of the obligations of a Seller hereunder, then such Seller shall
be deemed to have revoked the exercise of its Put Option and shall not be
entitled to have its Pro Rata Portion of Tutopia Shares purchased by the Company
at the Closing.

3.   Covenants of the Company.  The Company hereby covenants to UBS as follows:
     ------------------------

     (a) As soon as practicable following receipt of the UBS Put Notice, but in
any event no later than twenty (20) days thereafter, the Company shall file with
the Secretary of State of the State of Delaware a Certificate of Designation,
Number, Powers, Preferences and Relative, Participating and Other Rights (the
"IFX Preferred Certificate") authorizing a new series of preferred stock of the
Company (the "IFX Preferred Stock") substantially in the form of the Series C
Certificate (as defined below).  The IFX Preferred Stock shall have all of the
rights, preferences, privileges and restrictions of the Company's Series C
Convertible Preferred Stock (the "Series C Preferred Stock") set forth in the
Certificate of Designation, Number, Powers, Preferences and Relative,
Participating, Optional and Other Rights of Series C Convertible Preferred Stock
of the Company filed with the Secretary of State of the State of Delaware on
February 19, 2002, as amended from time to time (the "Series C Certificate");
provided, however, that upon a bankruptcy, liquidation, dissolution or winding
up of the Company, the holders of IFX Preferred Stock shall not be entitled to
receive out of the assets or funds of the Company by reason of their ownership
of such IFX Preferred Stock amounts in excess of the Stated Preference as is
provided with respect to the Series C Preferred Stock in Section 3(a)(i) of the
Series C Certificate.

     (b) At each Closing, (i) the shares of IFX Preferred Stock and/or IFX
Common Stock to be issued and sold to each Seller at such Closing shall have
been duly authorized and, when delivered, will be duly and validly issued and

defined in the Preferred Stock Purchase Agreement), other than the Stockholders
Agreement, (ii) the IFX Common Stock issuable upon conversion of the IFX
Preferred Stock will have been duly authorized, will have been reserved for

be free of Encumbrances, other than pursuant to the Stockholders Agreement, and
(iii) the shares of Common Stock issuable upon conversion of the IFX Preferred
Stock to be issued and sold to such Seller at the Closing and any shares of IFX

                                   RECITALS

     The Company desires to sell to the Purchasers, and the Purchasers desire to
purchase from the Company such number of shares of Series D Convertible
Preferred Stock set forth in Section 2 hereof, all on the terms and conditions
set forth herein.

     Simultaneously with the execution and delivery of this Agreement, the
Requisite Stockholders have consented to certain of the transactions
contemplated hereby.

                                   AGREEMENT

     In consideration of the premises and the mutual covenants, agreements,
hereinafter set forth, the parties to this Agreement agree as follows:

     1.   Authorization of the Securities; Nature of Agreement.
          ----------------------------------------------------

          (a)       Series D Preferred Stock. The Company has authorized the
                    ------------------------
issuance pursuant to the terms and conditions of this Agreement of shares of its
Preferred Stock, $1.00 par value per share, to be designated as Series D
Convertible Preferred Stock (the "Series D Preferred Stock"), as provided
                                  ------------------------
herein. The shares of Series D Preferred Stock have all of the rights,
preferences, privileges and restrictions set forth in the Certificate of
Designation, Number, Powers, Preferences and Relative, Participating, Optional
and Other Rights of Series D Convertible Preferred Stock of IFX Corporation (the
"Series D Certificate"), a copy of which, in the form to be filed with the
 --------------------
Secretary of State of the State of Delaware, is attached as Exhibit B hereto.
                                                            ---------

          (b)       Nature of Agreement. This Agreement insofar as it relates to
                    -------------------
the acquisition of a particular number of shares of the Series D Preferred Stock
by any Purchaser is a separate agreement between that Purchaser and the Company.
But this Agreement insofar as it relates to the rights, duties and remedies of
the Company and the Purchasers, from and after the Closing, shall be deemed to
be one Agreement.
<PAGE>

     2.   Sale and Purchase of Series D Preferred Stock. (a) Subject to the
          ---------------------------------------------
terms and conditions set forth in this Agreement, the Company agrees to sell to
the Purchasers, and each of the Purchasers severally and not jointly agrees to
purchase from the Company, the number of shares of Series D Preferred Stock
indicated opposite such Purchaser"s name on the Schedule of Purchasers (the
"Shares"), for a purchase price set forth in Section 3. The sale and purchase
 ------
of the Series D Preferred Stock shall take place at the offices of Kaye Scholer
LLP, 425 Park Avenue, New York, New York 10022, at 10:00 a.m., New York City
time, at a closing (the "Closing") to occur as soon as practicable after
                         --------
satisfaction or waiver of the conditions to Closing set forth in Sections 7 and
8. At the Closing, the Company will deliver to each Purchaser the Series D
Preferred Stock to be purchased by such Purchaser in the form of a single
certificate (or such greater number of certificates representing such shares as
such Purchaser may request), each dated the date of Closing and registered in
such Purchaser"s name (or in the name of such Purchaser"s nominee(s)), against
delivery by such Purchaser of the purchase price set forth in Section 3. If at
the Closing, the Company shall fail to tender to any Purchaser the Series D
Preferred Stock to be purchased by such Purchaser, or any of the conditions
specified in Section 7 shall not have been fulfilled to the satisfaction of such
Purchaser, such Purchaser shall, at its election, be relieved of all further
obligations under this Agreement, without thereby waiving any other rights such
Purchaser may have by reason of such failure or such nonfulfillment.

     3.   Purchase Price. At the Closing, each Purchaser shall pay a purchase
          --------------
price for the Shares to be purchased by it hereunder in an amount equal to the
sum of (a) the cash consideration indicated opposite such Purchaser"s name on
the Schedule of Purchasers plus (b) the transfer and assignment to the Company
of the shares of Series C Preferred Stock or Common Stock, as the case may be,
owned by such Purchaser indicated opposite such Purchaser"s name on the Schedule
of Purchasers. The cash portion of the purchase price shall be payable by the
payment to the Company or its order of immediately available funds and/or
conversion of indebtedness (subject to the following sentence) in the aggregate
amount of such cash portion of the purchase price. In the event that a portion
of such cash consideration is paid by a Purchaser in the form of conversion of
indebtedness, then (i) the principal amount of such converted indebtedness shall
be applied toward the payment of such cash portion of the purchase price, and
(ii) any accrued interest on such converted indebtedness shall be applied to the
purchase, at a purchase price equal to One Dollar and Twenty Cents ($1.20) per
share of shares of Series D Preferred Stock, in addition to the number of Shares
to be purchased by such Purchaser as set forth on the Schedule of Purchasers. In
addition, at the Closing, each Purchaser shall surrender the certificate or
certificates representing the shares of Series C Preferred Stock or Common Stock
owned by such Purchaser indicated opposite such Purchaser"s name, as the case
may be, to be assigned to the Company as part of the purchase price for the
Shares, which certificates shall be accompanied by appropriate stock powers.

          ---------------------------------------------
exceptions set forth in the Schedule of Exceptions attached as Exhibit C hereto
                                                               ---------

Company and each of its Subsidiaries has full power and authority (corporate and
other) to own, lease and operate its properties and assets and to operate the
Business as currently being operated.

               (i)   Except as set forth on the Schedule of Exceptions, the

limitation the Certificate) in connection with the consummation of the

Exceptions, neither the Company nor any Subsidiary is obligated or under any
liability whatsoever to make any payments by way of royalties, fees or otherwise
to any owner, licensor of, or other claimant to, any Intellectual Property, with
respect to the use thereof or in connection with the conduct of the Business, or
otherwise. The Company and each of its Subsidiaries has taken reasonable steps
to protect, maintain and safeguard the Intellectual Property material to the

disclosure would impair its value or validity, and has executed and has had
executed appropriate nondisclosure and confidentiality agreements and made all

the negotiation or consummation of this Agreement or the Other Agreements or any
of the transactions contemplated hereby or thereby. All such negotiations or the
consummation of this Agreement or the Other Agreements or any of the

claim against the Company, any Subsidiary or any of the Purchasers for any
brokerage or finder's commission, fee or similar compensation.

          (u)            No Undisclosed Liabilities.  Except as set forth on the

Subsidiary has any liabilities, obligations, claims, commitments or debts of any
nature, whether known or unknown, whether due or becoming due, or asserted or
unasserted (whether fixed, accrued, absolute, contingent, secured or otherwise).
The Schedule of Exceptions sets forth a true and complete schedule of accrued
liabilities and future payments due with respect to any acquisitions by the
Company or any Subsidiary of any equity securities or assets of any Person.

          (v)            Disclosure.  This Agreement (including the Schedules
                         ----------
and Exhibits hereto) does not contain any untrue statement of any material fact
or omits to state a material fact necessary in order to make the statements

material fact required to be stated therein or necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading.

          (a)    Investment Intent. The shares of Series D Preferred Stock to be
                 -----------------
acquired by and issued to the Purchaser pursuant to this Agreement are being
acquired by the Purchaser solely for its own account, for investment purposes
only, and with no present intention of distributing, selling or otherwise
disposing of them.

          (b)    Sophistication. Such Purchaser is able to bear the economic
                 --------------
risk of an investment in shares of the Series D Preferred Stock to be acquired
by it pursuant to this Agreement and can afford to sustain a total loss of such
investment, and has such knowledge and experience in financial and business
matters that it is capable of evaluating the merits and risks of the proposed
investment and therefore has the capacity to protect its own interests in
connection with the purchase of its respective shares of Series D Preferred
Stock.

          (c)    Illiquidity. Such Purchaser understands that there is no public
                 -----------
market for the shares of Series D Preferred Stock to be acquired by it and that
there may never be a public market for such stock, and that even if a market
develops for such stock such Purchaser may have to bear the risk of its
investment in such stock for a substantial period of time.

          (d)    Accredited Investor. Such Purchaser is an "accredited investor"
                 -------------------

warranties contained herein), such Purchaser has received such information as it
considers necessary or appropriate for deciding whether to acquire its
respective shares of Series D Preferred Stock.

          (e)    Brokers. No finder, broker, agent, financial advisor or other
                 -------
intermediary has acted on behalf of such Purchaser in connection with the

by each Purchaser, and each of the Other Agreements when executed and delivered
by each Purchaser who is a party thereto, will constitute the legal, valid and
binding obligations of such Purchaser, enforceable in accordance with their
terms, subject to applicable bankruptcy, insolvency, or other similar laws
affecting the enforceability of creditors rights generally and court decisions
with respect thereto, and the discretion of courts in granting equitable
remedies.

          (h)    No Conflict. The execution and delivery by each Purchaser of
                 -----------
this Agreement and the consummation of the transactions contemplated hereby by
each Purchaser will not result in any violation of or default under, any
provision of the organizational documents of such Purchaser, any contract to
which such Purchaser is a party or any applicable law, rule or regulation, which
violation or default could reasonably be expected to (i) affect the validity of
this Agreement or any agreement entered into pursuant hereto, (ii) affect in any
material respect any action taken or to be taken by such Purchaser pursuant to
this Agreement or any agreement entered into pursuant hereto or (iii) have a
material adverse effect on the properties, assets, business or operations of

Company nor any Subsidiary will, without the Purchasers' prior written consent,
take any action which would result in any of the representations or warranties
made by the Company in this Agreement not being true in any material respect at
and as of the time immediately after such action, or in any of the covenants
contained in this Agreement becoming incapable of performance. The Company will
promptly notify the Purchasers of any action or event of which it becomes aware
which has the effect of making incorrect any of such representations or
warranties in any material respect or which has the effect of rendering any of
such covenants incapable of performance. The giving of such notice shall not
relieve the Company of any liability or the failure of any condition to the
obligations of the Purchasers hereunder.

occur any event that should be set forth in an amendment or supplement to the
Information Statement, the Company will promptly prepare and mail to its
stockholders such an amendment or supplement. The Company will not mail any
Information Statement, or any amendment or supplement thereto, to which the
Purchasers reasonably object. Except with respect to information provided in
writing by UBS, LSC or ITI, the Company covenants that the Information
