                          ----------

                                   RECITALS

     The Company desires to sell to the Purchasers, and the Purchasers desire to
purchase from the Company such number of shares of the Series B Convertible
Preferred Stock set forth in Section 2 hereof for a total purchase price for all
shares of Series B Preferred Stock purchased hereunder equal to Fifteen Million
Four Hundred Sixty Three Thousand Nine Hundred Seventeen Dollars ($15,463,917).
The shares will constitute one hundred percent (100%) of all the issued and
outstanding shares of the Series B Preferred Stock of the Company as of the date
of the final closing thereof, all on the terms and conditions set forth herein.

     Simultaneously with the execution and delivery of this Agreement, the
Requisite Stockholders have executed and delivered a written consent to certain
of the transactions contemplated hereby, including an increase in the authorized
shares for the Stock Option Plan, adoption of the Performance-Based Stock Plan
and the issuance of shares in accordance with the Nasdaq rules and regulations.

                                   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 B Preferred Stock.  The Company has authorized the issuance
              ------------------------
and sale pursuant to the terms and conditions of this Agreement of 4,418,262
shares of its Preferred Stock, $1.00 par value per share, to be designated as
Series B Convertible Preferred Stock (the "Series B Preferred Stock"), as
                                           ------------------------
provided herein.  The shares of Series B 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 B Convertible Preferred Stock of IFX Corporation (the
"Series B 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
              -------------------
purchase of a particular number of the Series B 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.

     2.   Sale and Purchase of Series B Preferred Stock.  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 B Preferred Stock
indicated opposite such Purchaser's name on the Schedule of Purchasers (the
"Shares") for a purchase price of Three and 50/100 Dollars ($3.50) per share
 ------
(the "Per Share Price").  The sale and purchase of the Series B Preferred Stock
      ---------------
shall take place at the offices of Kaye, Scholer, Fierman, Hays & Handler, 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 B Preferred Stock
to be purchased by such Purchasers 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 the Closing and registered in such Purchaser's
name (or in the name of such Purchaser's nominee(s)), against delivery by such
Purchaser to the Company or its order of immediately available funds in the
amount of the purchase price for such shares of Series B Preferred Stock. If at
the Closing, the Company shall fail to tender to any Purchaser the Series B
Preferred Stock to be purchased by such Purchasers, 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.   [Intentionally Omitted].
           ---------------------

     4.   Representations and Warranties of the Company.  Subject to the
          ---------------------------------------------

standing under such laws (to the extent the concept of good standing is
recognized under the laws of such jurisdictions).  The Company and each of its
Subsidiaries is qualified, licensed or domesticated as a foreign corporation in
all jurisdictions where the failure to be so qualified, licensed or domesticated
would have a Material Adverse Effect. The 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.

                                       2

              -------------

connection with the consummation of the transactions contemplated by this
Agreement (the "Other Agreements") and to perform its obligations and consummate
                ----------------
all of the transactions contemplated hereunder and thereunder, including the
sale and issuance of the shares of Series B Preferred Stock to be purchased by
each Purchaser at the Closing.  All corporate proceedings have been taken and
all corporate authorizations have been secured which are necessary on the part
of the Company and each of its Subsidiaries to authorize the execution, delivery
and performance of this Agreement and each of the Other Agreements.

               (ii) This Agreement has been duly executed and delivered and
constitutes, and each of the Other Agreements when executed and delivered by the
Company, will constitute, legal, valid and binding obligations of the Company,
enforceable in accordance with their respective 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.

               (iii) The shares of the Series B Preferred Stock to be purchased
by each Purchaser at the Closing have been duly authorized and, when delivered,

hereof relating to premises currently or previously owned, leased or operated by
the Company or any of its Subsidiaries.  Complete and accurate copies of each
such report, or the results of each such investigation or audit, have been
provided to the Purchasers.

          (s)  Certain Practices.  Neither the Company nor any Subsidiary (nor
               -----------------
any constituent corporation of any merger of which the Company or any Subsidiary
is a surviving corporation, or other Person of which the Company or any
Subsidiary is the surviving corporation) nor any of their respective officers,
employees, directors, representatives or agents

                                      12


has, since the inception of the Business by the Company or any of its
Subsidiaries (or their predecessors): (i) taken any action in furtherance of any
boycott not sanctioned by the United States; (ii) entered into any contract or
agreement to conduct any transaction with any Governmental Authority, agent,
representative or resident of, or any Person based or resident in, any of the
following countries: Angola (UNITA); Burma (Myanmar); Cuba; Iran; Iraq; Libya;

such official in his official capacity; (2) inducing such official to do or omit
to do any act in violation of the lawful duty of such official; (3) receiving an
improper advantage; or (4) inducing such official to use his influence with a
Governmental Authority to affect or influence any act or decision of such
Governmental Authority; in order to assist the Company or any Subsidiary in
obtaining or retaining business for or with, or directing business to, any
person.

          (t)  Brokers.  No finder, broker, agent, financial advisor or other
               -------
intermediary has acted on behalf of the Company or any of its Affiliates in
connection with the offering of the Series B Preferred Stock or 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
transactions contemplated hereby or thereby will not give rise to any valid
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 Schedule
               --------------------------
of Exceptions or in the SEC Reports, neither the Company nor any 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 contained herein
or therein, in light of the circumstances under which they were made, not
misleading.  To the Company's knowledge, there are no facts that, individually
or in the aggregate, would have a Material Adverse Effect that have not been set
forth in this Agreement (including the Schedule of Exceptions).

          (w)  SEC Filings.  Since January 1, 1997, the Company has timely filed
               -----------
all forms, reports and documents with the SEC required to be filed by it
pursuant to the Federal securities laws and the rules and regulations of the SEC
thereunder, all of which complied in all material respects with all applicable
requirements of the Securities Act and the Exchange Act and

                                      13


the rules and regulations of the SEC thereunder. The above referenced forms,
reports and documents of the Company are sometimes collectively referred to
herein as the "SEC Reports." A true and complete list of the SEC Reports is set
forth in the Schedule of Exceptions. All documents required to be filed as
exhibits to the SEC Reports have been timely filed. None of the SEC Reports,
including without limitation any financial statements or schedules included
therein, at the time filed contained any untrue statement of a material fact or
omitted to state a 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.

          (x)  Financial Statements.  The consolidated balance sheets and the
               --------------------
related consolidated statements of income, stockholders' equity and cash flows
(including the related notes thereto) of the Company and its Subsidiaries
included in the SEC Reports complied as to form in all material respects with
the applicable accounting requirements and published rules and regulations of
the SEC with respect thereto, have been prepared in accordance with GAAP,
applied on a basis consistent with prior periods except as otherwise noted
therein, present fairly the consolidated financial position of the Company and
its Subsidiaries as of their respective dates, and the consolidated results of
their operations and their cash flows for the periods presented therein, and
reflect all adjustments necessary for the fair presentation of results for the
periods presented except as set forth on the Schedule of Exceptions.

          (y)  Availability and Transfer of Foreign Currency.  All requisite
               ---------------------------------------------
foreign exchange control approvals and other authorizations, if any, by any
Governmental Authority have been validly obtained and are in full force and
effect to assure:  (a) the ability of the Company and its Subsidiaries to make
any and all payments necessary to (i) each Purchaser for dividend payments on
the Common Stock and the Series B Preferred Stock, or (ii) any other party in
order to conduct the Business; (b) the ability of the Company's Subsidiaries to
make any and all payments of dividends and other distributions to the Company
and any and all other intercompany payments to or from the Company; and (c) the
availability of dollars to enable each Purchaser to convert its investment to
dollars, if necessary, if such Purchaser liquidates its investment in the Series
B Preferred Stock or the Common Stock.

          (z)  Absence of Changes.  Except as set forth in the Schedule of
               ------------------
Exceptions, since June 30, 2000, neither the Company nor any Subsidiary has:

               (i)    suffered any Material Adverse Effect;

aggregate;

               (vii)  transferred or granted  any rights under, or entered into
any settlement regarding the breach, misappropriation, infringement or violation

          (bb) Investment Company Act.  The Company is not, nor is it directly
               ----------------------
or indirectly controlled by or acting on behalf of, any Person that is an
"investment company" within the meaning of the United States Investment Company
Act of 1940, as amended.

purchased by and issued to the Purchaser pursuant to this Agreement are being be
cquired by the Purchaser solely for its own account, for investment purposes

          (c)  Illiquidity.  Such Purchaser understands that there is no public
               -----------
public market for the shares of Series B Preferred Stock to be purchased by it

               -------------------

Agreement has been duly executed and delivered 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

                                      17


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

stockholders such an amendment or supplement. The Company will not mail any
Information Statement, or any amendment or supplement thereto, to which the
