                                 IFX CORPORATION

                               PURCHASE AGREEMENT

     This Purchase Agreement is made and entered into as of the 15 day of June,
2000, by and among IFX Corporation, a Delaware corporation (the "Company"), and
each Person listed on the Schedule of Purchasers attached as Exhibit A hereto
(the "Schedule of Purchasers") who executes this Agreement as a Purchaser (such
Persons are referred to in this Agreement, collectively, as the "Purchasers" and
individually, as a "Purchaser"). Unless defined elsewhere herein, capitalized
and other defined terms shall have the meanings specified in Section 13.

                                    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 A Convertible
Preferred Stock determined in accordance with Section 2 and 3 hereof for a total
aggregate purchase price for all shares of Series A Preferred Stock purchased
hereunder equal to Twenty Five Million Dollars ($25,000,000) to be purchased in
two installments consisting of an initial investment of $14,900,000 (the
"Initial Share Aggregate Purchase Price") at the Initial Closing (as defined
below) and, subject to the terms and conditions herein, an additional investment
of $10,100,000 (the "Additional Share Aggregate Purchase Price") at the
Subsequent Closing (as defined below). The shares will constitute one hundred
percent (100%) of all the issued and outstanding shares of the Series A
Preferred Stock of the Company as of the date of the final closing thereof, all
on the terms and conditions set forth herein.

                                    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 A Preferred Stock. The Company has authorized the issuance
and sale pursuant to the terms and conditions of this Agreement of up to
2,030,869 shares of its Preferred Stock, $1.00 par value per share, to be
designated as Class I Series A Convertible Preferred Stock ("Class I Preferred")
or Class II Series A Preferred Stock ("Class II Preferred" and together with the
Class I Preferred, the "Series A Preferred Stock"), as provided herein. The
shares of Series A 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


<PAGE>   7

Other Rights of Series A Convertible Preferred Stock of IFX Corporation (the
"Certificate"), a copy of which, in the form to be filed with the Secretary of
State of the State of Delaware, is attached hereto as Exhibit B hereto. Upon
issuance, Shares of Series A Preferred Stock shall be designated either Class I
Preferred or Class II Preferred as provided in this Agreement.

         (b) Nature of Agreement. This Agreement insofar as it relates to the
purchase of a particular number of the Series A 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. Initial Sale and Purchase of Series A 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 Class I Preferred indicated
as the Initial Shares opposite such Purchaser's name on the Schedule of
Purchasers (the "Initial Shares") for a purchase price of Twelve and 31/00
Dollars ($12.31) per share (the "Initial Per Share Price"). The initial sale and
purchase of the Series A 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 "Initial Closing")
on the date hereof. At the Initial Closing, the Company will deliver to each
Purchaser the Series A 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 Initial 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 A Preferred Stock. If at the Initial Closing, the
Company shall fail to tender to any Purchaser the Series A 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. Subsequent Sale and Purchase of Preferred Stock. Subject to the terms
and conditions set forth in this Agreement, including, among other things,
receipt of HSR Approval, the Company agrees to sell to the Purchasers, and each
of the Purchasers severally and not jointly agrees to purchase from the Company,
such Purchaser's pro rata portion (based on the number of Initial Shares
purchased) of the number of shares of Class II Preferred (the "Additional
Shares") and for a per share price (the "Closing Per Share Price") determined as
follows:


                                      -2-
<PAGE>   8


         (a) If the Average Closing Price (as defined below) is less than or
equal to the Initial Per Share Price, then (i) the Closing Per Share Price shall
equal the Initial Per Share Price and (ii) the total number of Additional Shares
shall equal the Additional Share Aggregate Purchase Price divided by such
Closing Per Share Price.

         (b) If the Average Closing Price is greater than the Initial Per Share
Price but less than $14.29, then (i) the Closing Per Share Price shall equal the
Average Closing Price and (ii) the total number of Additional Shares shall equal
the Additional Share Aggregate Purchase Price divided by such Closing Per Share
Price.

         (c) If the Average Closing Price is greater than or equal to $14.29,
then (i) the Closing Per Share Price shall equal $18.74 and (ii) the total
number of Additional Shares shall equal 539,077 such that the weighted average
price per share of all shares purchased of the Initial Closing and the
Subsequent Closing shall be $14.29.

         (d) The "Average Closing Price" shall mean the average of the closing
prices per share of the Common Stock as reported on the NASDAQ Small Cap Market
and published in The Wall Street Journal for the period of five (5) consecutive
trading days ending with (and including) the trading day immediately preceding
the Subsequent Closing.

         The purchase and sale of such Additional Shares 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
"Subsequent Closing" and together with the Initial Closing, each a "Closing") to
be held as soon as practicable, but not more than ten (10) business days,
following receipt of HSR Approval. At the Subsequent Closing, the Company will
deliver to each Purchaser the Series A 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 Subsequent 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 A Preferred Stock. If at the Subsequent
Closing, the Company shall fail to tender to any Purchaser the Series A
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 be reason of such failure or such nonfulfillment.

            (i) The Company and each of its Subsidiaries is an entity duly

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

operate the Business as currently being operated.

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

committees thereof) since the date of its incorporation.

     (b) Authorization. The Company has all requisite right, power and authority
(corporate or otherwise) to execute and deliver this Agreement and each of the
other agreements and instruments referred to herein to be entered into by the
Company at or prior to a Closing (including the Certificate) in 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 A Preferred Stock to be purchased by each
Purchaser at the Initial Closing and Subsequent 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.

            (i) 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.

shares of Preferred Stock are issued and outstanding; and (B) immediately after

            (v) The Schedule of Exceptions sets forth a true and correct list of

<PAGE>   12

Applicable Law, (ii) any term of its Certificate of Incorporation or Bylaws (or
equivalent documents in its jurisdiction of organization), or (iii) any Contract
to which it is subject and which is material to the Business (collectively, the
"Material Instruments"). The execution and delivery by the Company of this
Agreement and the Other Agreements, the performance by the Company of its
obligations hereunder and thereunder and the consummation by the Company of the
transactions contemplated hereby and thereby, including the issuance and sale of
the Series A Preferred Stock, the issuance of the Conversion Shares and the
taking of any other action contemplated by this Agreement or the Other
Agreements, will not (i) result in (A) any violation of any Applicable Law, or
(B) any violation of any term of the Company's or any of its Subsidiaries'
Certificate of Incorporation or Bylaws (or equivalent documents), or (C) any
violation of or any conflict with or a default (with or without notice, lapse of
time or both) under any of the Material Instruments, which violation, conflict
or default might reasonably be expected to materially adversely affect the
ability of the Company or any of its Subsidiaries to satisfy its obligations
under this Agreement, any of the Other Agreements or any of the Material
Instruments, (ii) accelerate or constitute an event entitling the holder of any
indebtedness of the Company or any of its Subsidiaries to accelerate the
maturity of any such indebtedness or to increase the rate of interest presently
in effect with respect to such indebtedness, or (iii) result in the creation of
any Encumbrance upon any of the material properties or assets of the Company or
any of its Subsidiaries. The performance by the Company or any of its
Subsidiaries of its obligations and the enforcement of its rights under the
Material Instruments will not have a Material Adverse Effect.

         (f) Good Title. Except as set forth on the Schedule of Exceptions, the
Company and each of its Subsidiaries has good title to, a valid license to, or a
valid leasehold interest in, the properties and assets used by it, in each case
free and clear of all Encumbrances, except liens for current property taxes not
yet due and payable and any immaterial workmen's, repairmen's, warehouseman's
and carriers' liens arising in the ordinary course of business. The buildings,
equipment and other tangible assets of the Company and each of its Subsidiaries
are in all material respects in good operating condition and repair, free from
any known defects and are usable in the ordinary course of the Business; and the
Company and each of its Subsidiaries owns, or has a valid leasehold interest in
or license to use, all assets necessary for the conduct of the Business as
presently conducted.

         (g) Litigation.

            (i) Except as set forth on the Schedule of Exceptions, there are no

Company or any Subsidiary (or, to the best knowledge of the Company, any basis
therefor or threat thereof).

all Tax returns that are required to have been filed by it with all appropriate
Governmental Authorities (and all such Tax returns are true, complete and
correct in all material respects), (ii) has timely paid all Taxes owed by it or
withheld and remitted to the appropriate Governmental Authority all Taxes which
it is obligated to withhold and remit from amounts owing to any employee
(including social security taxes), creditor, customer or third party, and (iii)
has not waived any statute of limitations with respect to Taxes or agreed to any
extension of time with respect to a Tax assessment or deficiency. The assessment
of any additional Taxes for periods for which returns have been filed is not
expected to exceed the recorded liability therefor, and there are no material
unresolved questions or claims concerning the Tax liability of the Company or
any Subsidiary. There is no pending dispute with, or notice from, any taxing
authority relating to any of the Tax returns which, if determined adversely to
the Company or any Subsidiary, would result in the assertion by any taxing
authority of any valid deficiency in a material amount for Taxes, and to the
knowledge of the Company, there is no proposed liability for a deficiency in any
Tax to be imposed upon the properties or assets of the Company, the Business or
any Subsidiary. There are no federal, state, local or foreign Tax Encumbrances
on any asset of the Company, the Business or any Subsidiary (other than
Encumbrances for Taxes not yet due and payable).

Exceptions and the Registration Rights Agreement, the Company is not a party to
any agreement or commitment which obligates the Company to register under the
Securities Act of 1933, as amended (the "Securities Act"), or any other
securities law of any jurisdiction, any of its presently outstanding securities
or any of its securities which may hereafter be issued.

         (j) Offering. Subject to the accuracy of the Purchasers'
representations in Section 5 of this Agreement, the offer, issuance and sale of
the Series A Preferred Stock and the Conversion Shares constitute, and will
constitute, transactions exempt from the registration and prospectus delivery
requirements of Section 5 of the Securities Act and analogous provisions of the
Applicable Laws of all other jurisdictions, and the Company has obtained (or is
exempt from the requirement to obtain) all qualifications, permits and other
consents required by all Applicable Laws governing the offer, sale or issuance
of securities.

         (k) Insurance. The Schedule of Exceptions contains a true, complete and
correct list of all insurance policies covering the Business and the respective
material

maintains in full force and effect such insurance policies. Neither the Company
nor any Subsidiary is in default with respect to any provision contained in any
insurance policy. Neither the Company nor any Subsidiary has failed to give any
notice under any insurance policy in due time.

         (l) Certain Transactions. Except as set forth in the Schedule of

                                      -13-

No past, current, or planned activity, service or product of the Company or any

any Intellectual Property owned by the Company or any Subsidiary and material to
the operation of the Business which is the subject of any Encumbrance or other
agreement granting rights therein to any third party. Except as set forth on the
Schedule of 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 Business, including any Intellectual Property for which improper

appropriate filings and registrations in connection with the foregoing. Neither
the Company nor any Subsidiary has knowledge of any infringement by any third
party of any Intellectual Property of the Company or any Subsidiary. There has
been no judgment, decree, injunction, rule, or order rendered by any
Governmental Authority, and no claim made against the Company or any Subsidiary,
asserting the invalidity, abuse, misuse or unenforceability of any Intellectual
Property material to the operation of the Business, or that would limit, cancel,
or question the validity of, or the rights of the Company or any Subsidiary in,
any Intellectual Property material to the operation of the Business.

            (r) Environmental Matters.

request by any Governmental Authority, relating to any Environmental Law
involving the Company or any of its Subsidiaries.

                (ii) Neither the Company, nor to the knowledge of the Company,
any third party has released any Materials of Environmental Concern into the

owned, leased, operated or controlled by the Company. The Company is not aware
of any releases of Materials of Environmental Concern at parcels of real
property or facilities other than those owned, leased, operated or controlled by

property or facilities owned, leased, operated or controlled by the Company.

                (iii) Set forth in the Schedule of Exceptions is a list of all
environmental reports, investigations and audits of which the Company is aware

other third party) issued or conducted during the five years preceding the date
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

is the surviving corporation) nor any of their respective officers, employees,
directors, representatives or agents 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

Montenegro); or (iii) knowingly offered, promised, authorized or made, directly
or indirectly, (A) any unlawful payments under Applicable Laws, or (B) any
payments or other inducements (whether or not unlawful), to any government
official, including any official of an entity owned or controlled by a
government, political party or official thereof or any candidate for political
office, with the intent or purpose of: (1) influencing any act or decision of
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 A 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).

     5. Representations and Warranties of the Purchasers. Each Purchaser
severally (and not jointly) represents and warrants to the Company that:

         (a) Investment Intent. The shares of Series A Preferred Stock to be
purchased 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 A Preferred Stock to be purchased by it
pursuant to this Agreement and can afford to sustain a total loss of such
investment, and has such

                                      -19-
<PAGE>   25

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 A Preferred Stock.

         (c) Illiquidity. Such Purchaser understands that there is no public
market for the shares of Series A Preferred Stock to be purchased 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"
within the meaning of Regulation D promulgated under the Securities Act. In
addition (but without limiting the effect of the Company's representations and
warranties contained herein), such Purchaser has received such information as it
considers necessary or appropriate for deciding whether to purchase its
respective shares of Series A Preferred Stock.

         (e) Brokers. No finder, broker, agent, financial advisor or other
intermediary has acted on behalf of such Purchaser in connection with the
transactions contemplated by this Agreement or the Other Agreements.

         (f) Requisite Power and Authority. Each Purchaser has all necessary
power and authority to execute and deliver this Agreement and the Other
Agreements to which it is a party and to carry out their provisions. This
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.

         (g) 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
such Purchaser.

     6. Covenants.

1976, as amended (the "HSR Act") in connection with the consummation of the sale
of the Additional Shares contemplated herein and the acquisition by UBS of
preferred stock of Tutopia.com, Inc. The parties shall promptly respond to any
inquiries received from the Federal Trade Commission or the Antitrust Division
of the Department of Justice in connection with such filings and shall cooperate
and use their reasonable best efforts to cause the expiration or early
termination of the waiting period in connection therewith ("HSR Approval"). The

shall be deemed a condition precedent to the consummation of the sale of the
Additional Shares in addition to the conditions precedent applicable thereto set
forth in Section 7 and elsewhere in this Agreement. The costs and expenses
thereof (including filing fees) shall be borne by the Company.

         (c) Covenants Pending Subsequent Closing. Pending the Subsequent
Closing, neither the 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 advise 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.
