THIS AMENDMENT NUMBER 1 TO STOCKHOLDERS AGREEMENT (the "Stockholders Agreement")
AMONG IFX CORPORATION ("IFX"), UBS CAPITAL AMERICAS III, L.P., UBS CAPITAL LLC
(collectively "UBS"), INTERNATIONAL TECHNOLOGY INVESTMENTS, LC ("ITI"), JOEL
EIDELSTEIN ("Eidelstein"), MICHAEL SHALOM ("Shalom") and LEE S. CASTY ("Casty")
is entered into as of July 28, 2000, by and among the undersigned.

     WHEREAS, Casty has entered into that certain Stock Purchase Agreement dated
as of July 12, 2000, between Casty and Scott J. Bakal, not individually but
solely as Trustee of the Casty Grantor Subtrust (the "Subtrust"), pursuant to
which Casty will sell all of his shares of IFX to the Subtrust (the
"Transaction");

     WHEREAS, Casty desires to relinquish his ability to designate a director to
be elected to the Board of Directors of IFX; and

     WHEREAS, the undersigned are willing to agree that Casty shall not be
required to vote shares held by the Subtrust.

     NOW, THEREFORE, the undersigned agrees as follows:

     1.   In Section 1.1, the phrase "Casty Representative" shall be changed to
"Eidelstein Representative."

     2.   Section 2.1 is amended to read as follows:

     SECTION 2.1 Board Representation.
                 --------------------

          (a)  Effective on the date hereof, the Board shall, except as
     otherwise provided below, be comprised of seven (7) Directors of whom: (i)
     two (2) shall be designees of the Investor Stockholders (the "Investor
     Representatives"), (ii) one (1) shall be a designee of ITI (the "ITI
     Representative"), (iii) one (1) shall be a designee of Eidelstein (the
     "Eidelstein Representative"), (iv) one (1) shall be jointly designated by
     ITI and Eidelstein (the "Joint Representative") and (v) the others shall be
     Independent Directors acceptable to the Investor Stockholders (with such
     consent not to be unreasonably withheld) who, commencing with the election
     of Directors at the next annual meeting of stockholders, have been elected
     by the holders of a majority of the outstanding Voting Securities. The
     initial Investor Representatives shall be Charles W. Moore and Mark O.

                                                                   Exhibit 10.13

     shall be Joel Eidelstein, and the initial Joint Representative shall be
     Zalman Lekach. If, at any time, ITI and Eidelstein are unable to agree upon
     the designation of a Joint Representative, the Joint Representative shall
     be designated by Jose Leiman. Notwithstanding the foregoing, at such time
     as an Independent Director acceptable to the Investor Stockholders (with
     such consent not to be unreasonably withheld) and the holders of a majority
     of the outstanding Voting Securities has been elected to the Board, the
     Investor Stockholders shall only be entitled to designate one Investor
     Representative, and the Investor Stockholders shall thereafter, as promptly
     as practicable, take all action necessary to cause one of the Investor
     Representatives to resign from the Board.

          (b)  The Company shall take such action as may be required under
     applicable law (i) to cause the Board to consist of the number of Directors
     specified in clause (a), (ii) to include in the slate of nominees
     recommended by the Board the Investor Representatives, the ITI
     Representative, the Eidelstein Representative and the Joint Representative
     (collectively, the "Representatives"), with the remaining Directors to be
     Independent Directors acceptable to the Investor Stockholders (with such
     acceptance not to be unreasonably withheld) and (iii) to cause the Investor
     Representatives to be duly appointed in accordance with the foregoing and
     the Certificate of Designation. The Company agrees to use its reasonable
     best efforts to cause the election of the Representatives to the Board,
     including nominating such individuals to be elected as Directors as
     provided herein.

          (c)  Each of the Investor Stockholders, ITI and Casty agrees to vote,
     or act by written consent with respect to any Voting Securities
     beneficially owned by him or it, at each annual or special meeting of the
     stockholders of the Company at which Directors are to be elected or to take
     all actions by written consent in lieu of any such meeting as are necessary
     to cause the Representatives designated by the others in accordance with
     the terms of this Agreement to be elected to the Board and agrees to use
     his or its reasonable best efforts to cause the election of each such
     designee to the Board, including nominating such individuals to be elected
     as Directors.

          (d)  In the event that a vacancy is created at any time by the death,
     disability, retirement, resignation or removal (with or without cause) of
     any Representative, the remaining Directors and the Company shall cause the
     vacancy created thereby to be filled by a new designee of the party or
     parties that designated such Director as soon as possible, who is
     designated in the manner specified in this Section 2.1. Each of the
     Company, each Investor Stockholders, ITI and Casty hereby agrees to take,
     at any time and from time to time, all actions necessary to accomplish the
     same. Upon the written request of the Investor Stockholders, ITI and/or
     Eidelstein, as the case may be, each of the others shall vote, or act by
     written consent with respect to all Voting Securities beneficially owned by
     him or it and otherwise take or

                                       2

                                                                   Exhibit 10.13

     cause to be taken all actions necessary to remove any Director designated
     by the former. Unless the Investor Stockholders, ITI and/or Eidelstein, as
     the case may be, shall otherwise request in writing, none of the others
     shall take any action to cause the removal of any Director designated by
     the former.

          (e)  Without the written consent of the Investor Stockholders, each of
     the Company, ITI and Casty agrees not to take any action that would cause
     the number of Directors constituting the entire Board to be other than
     seven (7).

          (f)  The covenants and agreements set forth herein shall be subject to
     the fiduciary obligations of the designees of the Investor Stockholders,
     ITI and Eidelstein now or hereafter serving on the Board and shall not
     prevent the designees of the Investor Stockholders, ITI or Eidelstein now
     or hereafter serving on the Board from taking any action or refraining to
     take any action while acting in the capacity as a Director of the Company.
     The foregoing shall not limit the obligations of the Investor Stockholders,
     ITI and Eidelstein in their capacity as stockholders of the Company
     hereunder.

     3.   Section 3.4 is amended to read as follows:

     SECTION 3.4  Transfers by Casty.
                  ------------------

          (a)  Casty agrees that neither he nor any of his Affiliates shall
     Transfer more than the number of Shares of Common Stock permitted under
     Rule 144(e) of the Securities Act without the written consent of the
     Investor Stockholders, which consent shall not be unreasonably withheld or
     delayed or without compliance with Sections 3.5 and 3.6. Notwithstanding
     the foregoing, Casty may Transfer all or any of his Equity Securities (a)
     to any member of such Stockholder's family or to any trust for the benefit
     of any such family member of such Stockholder or to any other Affiliate,
     provided that any such transferee shall agree in writing with the Company
     and the Investor Stockholders as a condition to such Transfer, to be bound
     by all of the provisions of this Agreement to the same extent as if such
     transferee were such Stockholder, or (b) by will or the laws of descent and
     distribution, and further any transferee of Casty may Transfer Equity
     Securities to Casty; provided, however, in such event each such transferee
     shall be bound by all of the provisions of this Agreement to the same
     extent as if such transferee were such Stockholder; and provided, further,
     that each such transferee (other than the Subtrust) shall execute an
     irrevocable proxy appointing the original Stockholder (except in the case
     of death of the original Stockholder) transferring such shares as proxy to
     vote all such shares so transferred, such appointment shall be coupled with
     an interest, and all stock certificates representing such shares shall bear
     a legend providing notice of such appointment of proxy and the restrictions
     contained in this Agreement.

          (b)  The provisions of this Section 3.4 shall terminate upon the
     earlier of: (i) a Qualified Public Offering and (ii) the time at which the
     Investor

                                       3

                                                                   Exhibit 10.13

Stockholders and the other Holders own fewer than 50% of the number of shares of
Common Stock (determined on an as converted basis) that the Investor
Stockholders owned as of the Subsequent Closing (adjusted for stock splits,
combinations, stock dividends and the like).

     4.   The undersigned waive any of their rights under Sections 3.5 and 3.6
with respect to Transfers between Casty and the Subtrust.

     5.   Casty represents and warrants that as of the date hereof, he
individually owns 3,061,410 shares of the $.02 par value Common Stock of IFX and
that immediately after the effectiveness of the Transaction, that he will own no
shares.

     6.   The Subtrust represents and warrants that as of the date hereof, it
owns no shares of IFX and that immediately after the Transaction, it will own
3,061,410 Shares. The Subtrust further represents and warrants that the sole
beneficiaries of the Subtrust are Affiliates of Lee S. Casty.

     7.   The Subtrust acknowledges that it is subject to the provisions of the
Stockholders Agreement (including but not limited to Sections 3.4 and 2.1), to
the same extent as if it were Casty.

     8.   Casty acknowledges that he shall be subject to Sections 3.4 and 2.1 of
the Stockholders Agreement with respect to Shares that he acquires after the
date hereof.

     9.   The undersigned affirm and hereby ratify all other provisions of the
Agreement.

  IN WITNESS WHEREOF, the parties hereto have executed the AMENDMENT NUMBER 1 TO
STOCKHOLDERS AGREEMENT as of the date set forth in the first paragraph hereof.

                               TUTOPIA.COM, INC.

                               PURCHASE AGREEMENT

     This Purchase Agreement is made and entered into as of the 7th day of
August, 2000, by and among IFX Corporation, a Delaware corporation ("IFX"),
Latin Guide, Inc., a Delaware corporation ("Latin Guide") and Tutopia.com, Inc.,
a Delaware corporation (the "Company;" IFX, Latin Guide and the Company are
hereinafter collectively referred to as the "Sellers" and individually as a
"Seller"), 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 12.

                                    RECITALS

     The Company desires to sell to the Purchasers, and the Purchasers desire to
purchase from the Company, an aggregate of up to 11,890,606 shares (the
"Shares") of the Series A Convertible Preferred Stock, 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
11,890,606 shares of its Preferred Stock, $.001 par value per share, to be
designated as Series A Convertible Preferred Stock (the "Series A Preferred
Stock"). The shares of Series A Preferred Stock shall 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 A Convertible Preferred Stock of Tutopia.com, Inc., 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 (the "Certificate").

          (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.   Sale and Purchase of Series A Preferred Stock.
          ---------------------------------------------
<PAGE>

                                                                   Exhibit 10.14

          (a) Purchase and Sale at the Initial Closing. 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 A Preferred Stock
indicated opposite such Purchaser's name on the Schedule of Purchasers for a
price of $2.1025 per share. The 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") to occur as soon as practicable after
satisfaction or waiver of the conditions to Closing set forth in Sections 6 and
7. At the Initial Closing, the Company will deliver to each Purchaser the Series
A 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 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
Purchaser, or any of the conditions specified in Section 6 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. The closing of the purchase and sale of Shares
by any party exercising his/her/its co-investment rights under the Existing
Stockholders Agreement during the Stockholder Solicitation Period shall occur
simultaneously with the Initial Closing. At the Initial Closing, each such party
shall become a party to this Agreement and the Restated Stockholders Agreement
by signing such agreements and such party shall not be deemed a party to such
agreements until such Initial Closing.

          (b) Purchases and Sales Subsequent to the Initial Closing. If less
than all of the Shares are sold at the Initial Closing, subject to the terms and
conditions of this Agreement and, with the written consent of UBS, the Company
may sell up to the balance of the authorized but unissued Shares (the "Remaining
Shares") to such institutional investors, venture capital or private equity
firms or funds or strategic investors as the Company may determine with the
consent of UBS, at the same price per share as the Shares purchased and sold at
the Initial Closing. Any such sale shall be upon the same terms and conditions
as those contained herein, may occur in one or more closings ("Subsequent
Closing(s)") and such persons or entities shall become parties to this
Agreement, and the Restated Stockholders Agreement, and shall have the rights
and obligations of a Purchaser hereunder and thereunder. Such persons or
entities may become parties to such agreements by (i) executing copies of such
agreements by appending additional signature pages to such agreements containing
their signatures and (ii) appending additional pages to or revising Exhibit A
hereto. Any Subsequent Closing shall take place at a location and on a date and
time as the Company and such purchaser of Remaining Shares shall mutually agree
which shall be a Business Day no later than thirty

<PAGE>

                                                                   Exhibit 10.14

(30) days from the Initial Closing. The Initial Closing and any Subsequent
Closing are individually referred to herein as a "Closing" and, collectively, as
the "Closings."

     3.   Representations and Warranties of the Company. Subject to the
exceptions set forth in the Schedule of Exceptions attached as Exhibit C hereto
(the "Schedule of Exceptions"), the Sellers (jointly and severally, except that
the Company shall have no liability for representations and warranties relating
to IFX or Latin Guide) represent and warrant to each of the Purchasers that:

     (a)  Organization and Good Standing.

          (i)  Except as set forth in the Schedule of Exceptions, the Company
and each of its Subsidiaries is an entity duly organized and validly existing
under and by virtue of the laws of its state or country of incorporation and is
in good 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.

          (ii) The minute books of the Company and each of its Subsidiaries,
as previously made available to the Purchasers, contain accurate records of all
meetings of and resolutions of, or written consents by, its shareholders and its
board of directors (or committees thereof) since the date of its incorporation.

     (b)  Authorization.  Except as set forth in the Schedule of Exceptions:

          (i)  Each Seller (x) 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 such
party at or prior to any 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 (y) all corporate proceedings and
corporate authorizations which are necessary on the part of such Seller and each
of its Subsidiaries have been taken or secured to authorize the execution,
delivery and performance of this Agreement and each of the Other Agreements by
such Seller, it being understood and agreed that any sale pursuant to Section
2(b) hereof shall require approval of the Board of Directors of the Company.

          (ii) This Agreement has been duly executed and delivered and
constitutes, and each of the Other Agreements when executed and delivered by
each Seller

<PAGE>

party thereto, will constitute the legal, valid and binding obligations of such
Seller, 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 A Preferred Stock to be purchased by
each Purchaser at the applicable Closing have been duly authorized and, when
delivered, will be duly and validly issued and outstanding, fully paid and
nonassessable, and will be free of Encumbrances, other than those contained in
this Agreement, the Existing Stockholders Agreement, the Restated Stockholders
Agreement and the Certificate, existing under applicable securities laws or
created by the Purchasers. The New Common Stock of the Company issuable upon
conversion of the Series A Preferred Stock (the "Conversion Shares"), as of the
applicable Closing, will (x) be duly authorized, (y) be reserved for issuance
upon conversion of the Series A Preferred Stock issued at the applicable
Closing, and (z) when issued, be duly and validly issued and outstanding, fully
paid and nonassessable and free of Encumbrances, other than those contained in
this Agreement, the Existing Stockholders Agreement, the Restated Stockholders
Agreement and the Certificate, existing under applicable securities laws or
created by the Purchasers.

     (c)  Capital Stock.

          (i) (A) On the date hereof, the authorized capital stock of the
Company consists of (1) ten (10) million shares of Class A Common Stock, par
value $.001 per share (the "Class A Common Stock"), of which ten (10) million
shares of Class A Common Stock are issued and outstanding, (2) twenty-five (25)
million shares of Class B Common Stock, par value $.001 per share (the "Class B

which 11,833,333.34 shares of New Common Stock will be issued and outstanding,
and (2) twenty (20) million shares of Preferred Stock, of which 11,890,606

of which 11,890,606 shares of Series A Preferred Stock will be issued and
outstanding. (The Class A Common Stock, Class B Common Stock and New Common
Stock are collectively referred to herein as the "Common Stock.")

          (ii) Except as set forth in the Schedule of Exceptions or as expressly
contemplated hereby, the Company has not (A) issued or granted, (B) agreed to

Stock, or any other security of the Company or any of its Subsidiaries. Except

its Subsidiaries have been duly authorized and validly issued, are fully paid,
nonassessable and free of preemptive rights (other than those preemptive rights
set forth in the Schedule of Exceptions) and other Encumbrances other than those
existing under the Existing Stockholders Agreement, the Restated Stockholders
Agreement and organizational documents of the relevant entity or by virtue of
Applicable Laws, and were issued in compliance with all Applicable Laws,
including those regulating the offer, sale or issuance of securities.

          (iv) Except as set forth in the Schedule of Exceptions, no Person has
any rights of first refusal or similar rights or any preemptive rights in
connection with the issuance of the shares of Series A Preferred Stock or
Conversion Shares, or with respect to any future offer, sale or issuance of
securities by the Company, any of its Subsidiaries or any of its stockholders,

     (d)  Subsidiaries.

          (i) The name of each Subsidiary of the Company, the jurisdiction of

                                                                   Exhibit 10.14

          (e) Compliance With Material Instruments. Except as set forth in the
Schedule of Exceptions, the Company and each Subsidiary is not in violation of
(i) any 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 (in the case of the
Company, as amended by the Restated Certificate of Incorporation and Restated
By-Laws) (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. 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) There are no actions, proceedings, investigations (civil,
criminal, regulatory or otherwise), arbitrations, claims, demands or grievances
("Actions") pending against the Company or any Subsidiary (or, to the best
knowledge of the Company, any basis therefor or threat thereof).

<PAGE>

                                                                   Exhibit 10.14

          (ii)  There are no judgments unsatisfied against the Company or any
Subsidiary or consent decrees or injunctions to which the Company, any
Subsidiary or any assets of the Business are subject.

      (h) Tax Matters.  The Company and each of its Subsidiaries (i) has timely
filed (including extensions) 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 best 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).

      (i)    Registration Rights. Except as set forth in the Schedule of Excep
tions and the Restated Stockholders 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 4 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 assets of the Company and each Subsidiary. IFX and certain Subsidiaries
of IFX maintain 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
<PAGE>

                                                                   Exhibit 10.14

Company nor any Subsidiary has failed to give anynotice under any insurance
policy in due time.

      (l)    Certain Transactions. Except as set forth in the Schedule of
Exceptions, neither the Company nor any of its Subsidiaries is indebted, either
directly or indirectly, to any of the officers, directors, advisory board
members or stockholders of the Company or any Subsidiary, or to any Affiliates
of the foregoing, in any amount whatsoever, other than for payment of salary for
services rendered and reasonable expenses; except as set forth on the Schedule
of Exceptions, none of said officers, directors, advisory board members,
stockholders and their respective Affiliates are indebted to the Company or any
Subsidiary or, to the best knowledge of the Company, have any direct or indirect
ownership interest in, or any contractual relationship with, any Affiliates of
the Company or any Subsidiary or with any Person with which the Company or any
Subsidiary has a business relationship, or any Person which, directly or
indirectly, competes with the Company or any Subsidiary. Except as set forth in
the Schedule of Exceptions, no such officer, director, advisory board member or
stockholder, nor any of their respective Affiliates, is, directly or indirectly,
a party to or otherwise an interested party with respect to any contract,
agreement, arrangement or understanding with the Company or any Subsidiary other
than agreements for the issuance of stock options to any such Person or
Optionholder.

      (m)    Contracts.

             (i)  Except as expressly contemplated by this Agreement, or as set
forth in the Schedule of Exceptions, the Company and each of its Subsidiaries is
not a party to, or bound by, and none of their respective assets is or will be
subject to, any written or oral agreement, contract, commitment, order, license,
lease or other instrument and arrangement of the types described below (the
"Contracts"):

                  (A)    any pension, profit sharing, stock option, employee
      stock purchase or other plan providing for deferred, incentive or other

                  (o) Officers, Employees and Labor.

                        (i) The Company and each of its Subsidiaries has

plan which is required to be funded under Applicable Law. The Company has
delivered to the Purchasers true, correct and complete copies of all documents,
summary plan descriptions, insurance contracts, third party administration

            (v) Except for required contributions for the current plan year, no
material liability has been or is expected to be incurred by the Company under

knowledge of the Company, no event, transaction or condition has occurred or
exists that could result in any such liability to the Company or any of its
Subsidiaries or, following the Closing, the Company, its Subsidiaries, the
Purchasers or any such Benefit Plan.

            (vi) Except as set forth on the Schedule of Exceptions, each of the
Benefit Plans listed in the Schedule of Exceptions is and has at all times been
in compliance in all material respects with all applicable provisions of
Applicable Laws.

            (vii) Except as specifically set forth in the Schedule of
Exceptions, the execution and performance of the transactions contemplated by
this Agreement will not (either alone or upon the occurrence of any currently
planned additional or subsequent event) constitute an event under any Benefit
Plan or individual agreement that will or may result in any payment (whether of
severance pay or otherwise), acceleration, vesting or increase in material
benefits with respect to any employee, former employee, consultant, agent or
director of the Company or any Subsidiary.

     (p) Compliance with Laws. The Company and each of its Subsidiaries is not,
in any material respects, in violation of any Applicable Laws and has not
received notice of any such violation.

     (q) Intellectual Property. Except as set forth in the Schedule of

and is validly licensed under, all Intellectual Property material to the
operation of the Business, as conducted in the past, as presently conducted and
as contemplated to be conducted. Any such licenses are in full force and effect.
No past, current, or planned activity, service or product of the Company or any
Subsidiary infringes or conflicts with the Intellectual Property of any third
party. The Company and its Subsidiaries have taken appropriate steps and
measures to establish and preserve ownership of or right to use all Intellectual
Property material to the operation of the Business. The Company owns all rights
in and to any and all Intellectual Property used or planned to be used by the
Company or any Subsidiary, or covering or embodied in any past, current or
planned activity, service or product of the Company or any Subsidiary, which
Intellectual Property was made, developed, conceived, created or written by any
consultant retained, or any employee employed, by the Company or any Subsidiary.
To the Company's knowledge, no former or current employee, and no former or
current consultant, of the Company or any Subsidiary has any rights in any
Intellectual Property made, developed, conceived, created
<PAGE>

or written by the aforesaid employee or consultant during the period of his
retention by the Company or the Subsidiary which can be asserted against the
Company or any Subsidiary. The Company owns, or has full and unrestricted rights
to use, any and all domain names containing the word "Tutopia" (including the
word "Tutopia" in combination with any non-military extension, including
Tutopia.com, Tutopia.net and Tutopia.org.). The domain name Tutopia.com does not
and will not receive an amount of Internet traffic intended for any website or
webpage of the Company that would have a Material Adverse Effect. Except as set
forth on the Schedule of Exceptions, neither the Company nor any Subsidiary has
knowledge of 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 or unauthorized disclosure would impair
its value or validity, and has executed and has had executed appropriate
nondisclosure and confidentiality agreements and made all 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.

            (i)  The Company has complied in all material respects with all
applicable Environmental Laws. There is no pending or, to the knowledge of the
Company, threatened civil or criminal litigation, written notice of violation,
formal administrative proceeding, or investigation, inquiry or information
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
environment at any parcel of real property or any facility formerly or currently
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
the Company that could reasonably be expected to have an impact on the real
property or facilities owned, leased, operated or controlled by the Company.

               (iii) The Company is not aware of any environmental reports,
investigations and audits (whether conducted by or on behalf of the Company or a
third party, and whether done at the initiative of the Company or directed by a
Governmental Authority or 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.

          (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 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

(Myanmar); Cuba; Iran; Iraq; Libya; North Korea; Sudan; Syria; and the Federal
Republic of Yugoslavia (Serbia and 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 in the Schedule of
Exceptions or in the Financial Statements, 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
<PAGE>

                                                                   Exhibit 10.14

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) Financial Statements. The Company has provided the Purchasers with

financial projections of the Company and its Subsidiaries for the period from
July 1, 2000 through August 31, 2001, copies of which are attached hereto as

Statements (excluding any projections) fairly present the true, complete and
correct financial position, results of operation and statements of cash flow of
the Company and its Subsidiaries on a consolidated basis as of the dates and for
the periods indicated therein and have been prepared in accordance with GAAP
(except as otherwise indicated therein), subject to customary year-end
adjustments and without notes. The financial projections referred to in clause
(B) above have been prepared in good faith based upon the Company's books and
records and assumptions, which the Company believes are reasonable as of the
date of this Agreement.

          (x) 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 A 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
A Preferred Stock or the Common Stock.

          (y) Absence of Changes. Except as set forth in the Schedule of

     4.   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 and the
related Conversion Shares 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.
<PAGE>

                                                                   Exhibit 10.14

          (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 the related Conversion Shares 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 A Preferred Stock and the related Conversion Shares.

          (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 the
related Conversion Shares 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"

     unenforceable covenant shall be deemed eliminated from these provisions for
     the purpose of those proceedings to the extent necessary to permit the

     only third party ordinary course accounts payable ("Permitted
     Indebtedness"). To the extent that ordinary course accounts payable as of
     the Initial Closing are in an amount less than $2 million, then, upon

     constituting all or a portion of such difference by LGI or IFX, the Company
     shall reimburse IFX and/or LGI, as the case may be, for the cost thereof,
     within five (5) business days of the presentation of such receipts to the
     Company. Any amount owed to IFX or any Subsidiary thereof (other than the
