and its subsidiaries ("CUSTOMER").

WHEREAS, Provider is an Internet service provider offering a wide range of
services for businesses in  Latin America; and

WHEREAS, CUSTOMER wishes to purchase Hourly Dial Access services ("Service")
from Provider in Latin America  for the purpose of reselling such Service to its
customers (each of which shall be an "END-USER" as defined below and,
collectively, the "END-USERS") under a private label.

NOW, THEREFORE, in consideration of the foregoing and of the mutual covenants
and promises set forth herein, the parties, intending to be legally bound,
hereby agree as follows:

                                                                   Exhibit 10.15

          1.8  Service Agreement

 "Service Agreement" means a legally binding agreement between CUSTOMER and an

 Agreement.

  .

     2.  Resale of Services.

          2.1  General.

 On the terms and conditions set forth herein, CUSTOMER shall purchase from
 Provider, and Provider shall sell to CUSTOMER for resale to its END-USERS,
 Service, as described herein, at the prices described in Schedule A.  Provider
 also agrees to provide such Services under the minimum service standards set
 forth in Schedule B.  Provider shall invoice CUSTOMER in accordance with
 Section 4 for Service commencing on the first day END-USER accesses the
 Network.

          2.2  Service.

 Provider shall provide to CUSTOMER, for resale to its END-USERS, Hourly Dial
 Access through dialup telephone service through the POPs in which Provider
 provides Service, for the fees set forth in Schedule A.  Each END-USER will be
 solely and exclusively responsible for obtaining analog telephone service to
 place the data call to Provider's POP, and for all charges relating to such
 service (unless CUSTOMER assumes such obligations on behalf of its END-USERS).
 Provider assumes no liability or responsibility to CUSTOMER, END-USER or any
 third party for long distance toll charges, or any government applied charges,
 incurred by CUSTOMER, END-USER or any third party using the Service.  Customer
 shall include a disclaimer to this effect in its Terms of Usage with each End
 User.

          2.3  Limits on Orders.

 As of the Effective Date, CUSTOMER may order Service on behalf of its present
 or future END-USERS and there shall be no limit on the number of END-USERS who
 may use the Network.  CUSTOMER acknowledges, however, that Network capacity
 cannot be guaranteed.  Therefore, Provider may limit CUSTOMER'S requests to add
 additional hours if there is insufficient capacity on the Network or in the POP
 to provide such number of hours requested by reasonable prior written notice to
 CUSTOMER, subject to Provider's obligation to provide the Minimum Services
 pursuant to Section 3.4.  Notwithstanding the foregoing, Provider shall use
 commercially reasonable efforts to accommodate any request from CUSTOMER to
 increase the hours above the amounts Provider agreed to provide pursuant to
 Section 3.4 below, provided that Provider cannot make any guarantee regarding
 its ability to meet such requests.  To increase the likelihood that Provider
 can fulfill such request,  Provider shall maintain excess network capacity at
 least sufficient to support capacity in a given month based on the average
 growth rate of the previous 3 months + / - 5% of such average.

          2.5  Addition of Provider Services.

 The parties may agree to include additional Provider services, to include DSL,
 Web Hosting, and Co-location services when available, under this Agreement from
 time to time.  If so, such additional Provider services shall be added only
 after mutual agreement on pricing and by a written modification to this
 Agreement.

           2.6  License for Services.

                    2.6.1  Grant of License.
Subject to the terms of this Agreement, Provider hereby grants to CUSTOMER,
within the territories in which Provider operates from time to time, a non-
exclusive, revocable license to, market, distribute and resell the Service
directly to END-USERS under CUSTOMER'S private label, subject to the terms and
conditions hereof. Customer may not resell the Service to anyone who is not an
END-USER.

                    2.6.2  Limitations on License.

The grant of the foregoing license shall not entitle or in any way be construed
to entitle CUSTOMER to: (a) use Provider's trademarks, trade names, copyrighted
material, service marks and/or logos in connection with CUSTOMER'S sales,
advertisements and promotion of the Services, except in materials provided (or
approved prior to CUSTOMER'S use thereof) by Provider; (b) sublicense or assign
any of its rights under this Agreement, except as may be expressly permitted by
this Agreement; or (c) make any agreement or incur any liability for or on
behalf of Provider, except as may be expressly permitted by this Agreement.

           2.7  Second-Level Technical Support.

Provider, through its staff or through a third party reasonably acceptable to
CUSTOMER, shall provide directly to CUSTOMER'S designated technical contacts
only (as identified by CUSTOMER on a Provider-provided form), at no additional
charge, reasonable second-level technical support for the Services provided
herein and for Network problems. However, under no circumstances shall Provider
be obligated to provide any type of technical support, customer service, or
problem escalation support directly to END-USERS. CUSTOMER shall not disclose to
its END-USERS any of the contact information for Provider's or the third party's
staff provided to CUSTOMER for its exclusive use.

           2.8  Provider POPs.

Provider may change the location of an existing POP, and/or change the means for
accessing such POP (i.e., access numbers) as it, in its sole discretion, deems
appropriate; provided, however, that if the effect of such change is to
materially diminish the geographical coverage or capacity (on the same Dial-In
basis) as serviced by the POP prior to such change, CUSTOMER shall have the
right, in its sole discretion, to provide access from another service provider
for such POP, without any penalty, upon thirty (30) days written notice. In the
event Provider deems it necessary to close an existing POP, Provider shall
provide CUSTOMER with sixty (60) days prior written notice thereof.

     3.  CUSTOMER'S Obligations.

           3.1  Technical Support, Customer Service, and Problem Escalation
     Support
CUSTOMER shall be exclusively responsible for all technical support, customer
service, and problem escalation support for its END-USERS. Under no
circumstances shall CUSTOMER refer END-USER phone calls, e-mail, or other
communications to any Provider or third party staff. All communications by
CUSTOMER relating to END-USER problems or concerns shall be made directly and
exclusively between Provider (or its designated third party) and CUSTOMER's
designated technical contacts.

           3.2  END-USER Billing.
CUSTOMER shall be responsible for all pricing and service plans, taxes and other
governmental charges, billing and collections with respect to END-USERS.
CUSTOMER is responsible for payment of all Provider charges, pursuant to Section
4 hereof, regardless of whether Customer is paid by its END-USERs.
To the extent that Provider has the ability to determine what the END USER pays
for local telephone access costs, Provider and CUSTOMER shall mutually agree on
the discounts or other benefits that

                                      -3-

                                                                   Exhibit 10.15

 Provider will make available to the END
 USER. Such discounts or benefits shall be at least equal to the best discounts
 or benefits that other  free ISP's in the same market offer to their end users.

          3.3  Limitation on Warranties and Representations.

 Neither CUSTOMER nor its agents shall offer warranties or representations for
 the Service which would obligate or otherwise bind Provider beyond any warranty
 or representation expressly set forth in this Agreement.

          3.4  Forecast and Request.

 Prior to the end of each month, CUSTOMER shall send to Provider, a three month
 rolling forecast (each, a "Forecast") of the number of END-USERS and  hours
 expected to be utilized by Customer under this Agreement and the POPs to which
 they are expected to connect in the following three months.  The Forecast shall
 determine the number of hours that Provider shall provide to Customer during
 the last month of the Forecast (the first two months of the Forecast to be used
 by Provider solely for planning purposes only).  The  Forecast may indicate an
 increase or decrease over prior periods.  With respect to the final month of
 each Forecast, Provider may either fully agree with the Forecast (an "Agreed
 Forecast"), partially agree with the Forecast (a "Partially Agreed Forecast")
 or reject the Forecast (a "Rejected Forecast"). The parties agree that Provider
 will not disagree with any Forecast with respect to any month below 4.5 million
 hours ("Minimum Services").

 The first forecast must be delivered within 15 days of the Effective Date.

 With respect to an Agreed Forecast, Provider shall provide the Hours forecasted
 for the third month of the Forecast.

 With respect to a Partially Agreed Forecast, Provider shall provide the Hours
 agreed for the third month of the Forecast to the extent that Provider agrees
 with the Forecast.  To the extent that Provider does not agree with the
 Forecast, Customer may elect to choose another Provider for such non-agreed
 hours.

 With respect to a Rejected Forecast, CUSTOMER shall be free to pick a different
 Provider of Service for the third month of the Forecast.

 CUSTOMER may request additional hours in excess of the amount set forth in any
 Forecast for the first two months of any Forecast.  However, if Provider is not
 willing to provide such level of Service, Customer may purchase such Service
 elsewhere.

 With respect to an Agreed or Partially Agreed Forecast or request, the Customer
 will pay for the hours used as described in Schedule A and in accordance with
 Section 4.

 With respect to a Partially Agreed Forecast or a Rejected Forecast, Customer
 may at its sole option choose to force Provider to satisfy the Forecast (an
 "Enforced Forecast"), up to the lower  of: a) the Forecast or b) a projected
 compounded monthly growth of 25%.

 If Customer elects to make Provider accept an "Enforced Forecast" with respect
 to the third month of the Forecast, Customer will pay Provider for such month
 the higher of: (a) the total amount of hours committed to be provided by the
 Provider multiplied by the effective hourly rate set forth in Section 3 of
 Schedule A, divided by 1.25 for the first six months after the date of this
 Agreement, 1.175 for the next six months, and 1.10 for the second year and the
 third year, whether or not such hours are actually used, and (b) the pricing
 schedule set forth in Schedule A in accordance with Section 4.  Noncompliance
 of this section by Provider shall not be considered a material breach of this
 Agreement if Provider maintains an accessibility level above 95% as required by
 the second paragraph of Schedule B of this Agreement.

With respect to a Partially Agreed Forecast or a Rejected Forecast, Provider
shall have, in the following month, the priority to provide all rejected hours
that Customer has not purchased from third parties.
In addition, when any commitment with such third parties expires, Provider shall
have priority to provide any such hours that CUSTOMER still requires.

     3.5  Customer's Obligation to Provider.
Provider will have priority as Customer's Hourly Dial Access service provider in
those POPs in Latin America in which Provider has a presence at the time of the
Effective Date (with the express exclusion of the US) (the "Regions"); provided
that (i) the quality and availability of the Services in the applicable Region
shall be at least equal to those available to Customer from any other
telecommunications service provider and to the extent that sufficient
telecommunications capacity is available to adequately service Customer's
forecast and/or requests in the Regions, and (ii) Provider is in compliance with
this Agreement. Provider's services will be provided through Provider's wholly-
owned or controlled in-country subsidiaries.

     4.  Payment.

           4.1  Payment Terms.
Provider shall invoice CUSTOMER monthly, in arrears for Service provided
hereunder, including any amounts in excess of the Minimum Revenue Commitment. In
every case, CUSTOMER agrees to pay for all Service utilized by CUSTOMER, subject
to the terms and conditions hereof. All invoices will be payable within thirty
(30) days of date of invoice (the "Due Date").

           4.2  Late Payment Charges.
Delinquent payments are subject to a late payment charge accruing from the Due
Date at the rate of one percent (1%) per month, of the amount due (but not to
exceed the maximum lawful rate). Late payment charges shall be automatically
added to the next invoice. Late payments shall also be indexed for inflation
based on the local consumer price index.

          4.3  Consequences of Non-Payment.
In the event CUSTOMER does not remit payment for "Undisputed Charges" (defined
as all charges invoiced to CUSTOMER except for any specified amounts which
CUSTOMER disputes in good faith, with reference to specific provisions of this
Agreement, and with supporting factual documentation, if any) within fifteen
(15) days after the Due Date, Provider shall give 15 days prior written notice,
delivered via fax transmission and overnight courier, for CUSTOMER to cure such
breach. After expiration of such period, Provider may, at its option and in
addition to the late payment charges set forth in Section 4.2, suspend Service
to CUSTOMER and/or END-USERS. Provider shall resume providing Service as soon as
commercially reasonable upon receipt of such payment (including late payment
charges), and in such event CUSTOMER shall pay Provider a reasonable
reconnection fee (if applicable), which shall be invoiced and paid in accordance
with this Section. Notwithstanding anything to the contrary contained in this
Agreement, CUSTOMER shall be responsible for payment due to the extent that such
amounts relate to CUSTOMER failure to reach the Minimum Revenue Commitment as
set forth in Schedule A. CUSTOMER shall not offset or deduct any amount owed to
Customer from END-USERS notwithstanding that Customer has not received payment
from END-USERS.

     5. Term and Termination.

           5.1 Term.
The initial term of this Agreement shall be three  (3) years beginning on the
Effective Date of this agreement.

          5.2 Renewal.

 Following the initial three (3) year term, this Agreement will be renewed for a
 one-year term if either  party hereto so elects in writing within 90 days prior
 to the end of the initial term, provided, that a Change of Control (as defined
 below) has not taken place.   If a Change of Control of either party has
 occurred prior to the end of the initial three (3) year term such party shall
 have the right to terminate this Agreement upon expiration of the three (3)
 year term and the other party shall not have the right to extend for the one
 (1) year renewal term as provided above.  If this Agreement is  so renewed,
 Customer shall be obliged to purchase from Provider during each month of the
 renewal term the lower of: a) 20% of the total hours to be used by Customer for
 providing internet service to its End Users or b) four (4) million hours per
 month for sale to Customer's End Users.  The price for such services shall be
 as provided in Schedule A .  After the first 12 month renewal term, this
 Agreement shall automatically continue upon the same terms and conditions for
 subsequent one-year periods unless terminated by either party upon  written
 notice given at least sixty (60) days prior to the end of the applicable one-
 year period.

          5.3 Termination.

               5.3.1  By Either Party.

 Either party may terminate this Agreement if the other party has materially
 breached this Agreement and has failed to cure such breach within thirty (30)
 days after the non-breaching party has given written notice by fax transmission
 and overnight courier  clearly specifying such breach.  Further, Customer  may
 terminate this Agreement as set forth in Schedule B.

               5.3.2  Other Termination.

(a)  Upon termination of this Agreement for any reason at the end of the initial
     or any subsequent term, Provider, upon request of CUSTOMER shall continue
     to provide Services under the terms herein for no more than three (3)
     commencing at the end of the term then in effect, provided that CUSTOMER
     shall continue to make payments for such Services rendered as set forth in
     Section 4, at the applicable rates described in Schedule A.

(b)  In case of termination as a result of failure of the parties to reach an
     acceptable "re-negotiated" price, as provided for in Schedule A, then
     CUSTOMER shall transfer all of its End-Users off of the Provider Network
     within a minimum period of  three (3) months after the date of termination,
     and Provider shall continue to provide Services for this three (3) month
     period, as set forth herein.

     8.  Indemnity Provisions.

           8.1  By Provider.
Provider will defend, indemnify and hold CUSTOMER harmless from and against any
losses arising out of any claim by an END-USER which is based on any warranty,
promise or representation made by Provider to Customer under this Agreement
relating to Provider's obligations to provide the Service. Failure by the
CUSTOMER to include in its Service Agreements with END-USERS the provisions
required by this Agreement (Sections 2.2 and 7.2) shall relieve Provider from
the responsibilities set forth in this Section 8.1 to the extent such failure is
reasonably related to the alleged losses.

           8.2  By CUSTOMER.
CUSTOMER will defend, indemnify and hold Provider harmless from and against all
claims, complaints, losses, costs and expenses asserted by third parties to the
extent they arise out of or in connection with (a) CUSTOMER'S breach of or
default of any covenant or provision of this Agreement, (b) any grossly
negligent or willful act or omission or violation of Section 3.4 by CUSTOMER or
any of its END-USERS, or their respective directors, officers, owners, employees
or agents, or (c) any violation or alleged violation by CUSTOMER or END-USERS of
any and all applicable rules, regulations, statutes, codes, ordinances and other
requirements, whether federal, state, local, foreign, or international, in
connection with the matters contemplated by this Agreement. Provider will
defend, indemnify and hold CUSTOMER harmless from and against all claims,
complaints, losses, costs and expenses asserted by third parties to the extent
they arise out of or in connection with (a) Provider's breach of or default of
any covenant or provision of this Agreement, (b) any grossly negligent or
willful act or omission or violation of Section 3.4 by Provider or its
directors, officers, owners, employees or agents, or (c) any violation or
alleged violation by Provider of any and all applicable rules, regulations,
statutes, codes, ordinances and other requirements, whether federal, state,
local, foreign, or international, in connection with the matters contemplated by
this Agreement.

           8.3  Defense Obligations.
The indemnifying party under Section 8.1 or 8.2, above, shall assume the defense
of any claim qualifying for indemnification with counsel reasonably satisfactory
to the other party, and the other party shall cooperate to the extent reasonably
requested by the indemnifying party. The other party may employ its own counsel
in any such case, and shall pay such counsel's fees and expenses. The
indemnifying party shall have the right to settle any claim for which
indemnification is available; provided, however, that to the extent that such
settlement requires the other party to take or refrain from taking any action or
purports to obligate the other party, then the indemnifying party shall not
settle such claim without the prior written consent of the other party, which
consent shall not be unreasonably withheld, conditioned or delayed.

     9.  Nondisclosure.

           9.1 Confidential Information.
Provider and CUSTOMER agree that all information (whether in writing, orally or
in any other format) disclosed by either of them to the other during the
negotiation of this Agreement or to be disclosed during the performance of this
Agreement including all such exchanges which have taken place prior to the
execution of this Agreement (without regard to whether information has been
expressly marked or otherwise designated as confidential or proprietary) shall
constitute "Confidential Information"; provided, however, that Confidential
Information shall not include information that is or becomes publicly known
through no wrongful act of either Party (or any of its employees), has been
approved for release by written authorization of the originating Party, or has
been disclosed pursuant to a requirement of a government agency or of law.
During the term of this Agreement, and at all times thereafter, the Party to
whom Confidential Information has been imparted shall maintain such information
as confidential and shall not disclose or permit the same to be disclosed to any
person or entity. Each Party shall take all reasonable steps to minimize the
risks of disclosure of Confidential Information. Each of the Parties further
agree that the unauthorized disclosure by it of Confidential Information
received from the other shall cause irreparable harm and significant injury to
the other which may be difficult to ascertain. Accordingly, each Party agrees
that the other shall be entitled to equitable relief, including, without
limitation, an immediate injunction enjoining any breach by it of this Section,
in addition to all other remedies available to such Party at law or in equity.
The Parties agree that the obligations in this Section shall survive the
termination or expiration of this Agreement.

fire, catastrophe, governmental prohibitions or regulations, telephone company
equipment failure or delays, international bandwidth provider failure or delays,
viruses which did not result from the acts or omissions of Provider, its
employees or agents, national emergencies, power failures, insurrections, riots

incurred as a result of such act of force majeure, and Provider shall act with
diligence to correct such force majeure.

international bandwidth provider failure or delays, Provider shall contract with

nor shall it be construed to be a waiver of any such breach or default, or an
acquiescence therein, or of any similar breach or default thereafter occurring;
nor shall any waiver of any single breach or default be deemed a waiver of any
other breach or default theretofore or thereafter occurring.  Any waiver,
permit, consent or approval of any kind or character on the part of either party
of any breach or default under this Agreement, or any waiver on the part of
either party of any provisions or conditions of this Agreement must be made in

                           Revenue Sharing Agreement

          This Revenue Sharing Agreement (this "Agreement") dated as of August
31, 2000 is entered into by IFX Corporation (together with its subsidiaries,
"provider") and Tutopia.com, Inc. (together with its subsidiaries "customer").

          Provider is an Internet service provider offering a wide range of
services for business in Latin America. Provider and Customer have entered into
that certain Dial Access Agreement effective as of the date hereof (the "Dial
Access Agreement") under which Customer has agreed to purchase Hourly Dial
Access services from Provider in Latin America and Provider has agreed to sell
such Services to Provider. Capitalized terms used but not defined herein shall
have the meanings given to them in the Dial Access Agreement.

          In connection with providing the Services to Customer, Provider may
receive Telco Revenues (as defined below) from one or more local telephone
carriers or other telecommunications infrastructure providers ("Telcos") which
Provider has engaged to "terminate" (as such term is commonly used by
telecommunications companies) calls made by Customer's End-Users in accessing
Provider's Network. This Revenue Sharing Agreement is being entered into by the
parties in order to set forth how such Telco Revenues will be shared by Provider
and Customer.

          Accordingly, Provider and Customer hereby agree as follows:

          1.   "Telco Revenue" means any and all cash payments or credits paid
or granted by a Telco to or for the benefit of Provider as an inducement to
terminate telecommunication calls at such Telco. In connection with the
negotiation of call termination arrangements with Telcos, Provider will use its
reasonable best efforts to obtain the agreement of the Telco to provide any
consideration or benefit granted as an inducement to terminate telecommunication
calls at such Telco in the form of a direct cash payment or credit from the
Telco to Provider.

          2.   All Telco Revenues received by Provider that are based on the
number of hours and/or minutes "terminated" by Telcos as a result of Network
traffic generated by Customer pursuant to the Dial Access Agreement ("Tutopia
Generated Telco Revenues") shall be shared by Provider and Customer as follows:

          (a)  with respect to Tutopia Generated Telco Revenues generated from
               the date of this Agreement through December 31, 2000, Provider
               shall be entitled to receive 100% of Tutopia Generated Telco
               Revenues; and

          (b)  with respect to Tutopia Generated Telco Revenues generated from
               January 1, 2001 through the first (1st) anniversary of the date
               of this Agreement, Customer shall be entitled to receive 75% of
               Tutopia Generated Telco Revenues and Provider shall be entitled
               to receive 25% of Tutopia Generated Telco Revenues.

          3.   Provider shall deliver a monthly statement to Customer itemizing
all Tutopia Generated Telco Revenues reported by Telcos to Provider since the
previous statement. Such monthly statement shall be provided by Provider to
Customer as soon as practicable but in any event no later than 30 days after the
end of each calendar month.

          4.   Provider shall pay to Customer the amount of each Tutopia
Generated Telco Revenue within thirty (30) days of Provider's receipt thereof
from the applicable Telco.

          5.   From time to time Customer shall have the right to audit
Provider's records relating to the determination of Tutopia Generated Telco
Revenues (including without limitation all oral or written agreements with
Telcos relating to the termination of calls), and discuss such records with
Provider personnel, upon reasonable advance notice of no less than five (5)
business days and during normal business hours, but not more often than once in
any six (6) month period. In connection with any such audit, to the extent
reasonably requested by Customer, Provider shall use its reasonable best efforts
to provide access to the books and records of any Telco utilized by

                                                                   EXHIBIT 10.16

Provider to "terminate" calls (to the extent such books and records relate to
the provision of services by such Telco to Provider) and to such Telco's
personnel. Customer shall bear the cost of any such audit unless it is
determined that the Tutopia Generated Telco Revenues were misstated in
Provider's favor during the period audited by more than five percent (5%), in
which case, Provider shall bear the cost of such audit. Customer shall keep all
such records (as well as any other information disclosed by Provider to Customer
pursuant to this Agreement) confidential, except as required by applicable law.

          6.   This Agreement and any issues arising out of or in relation
thereto shall be governed by the law of Florida applicable to contracts to
performed wholly within that state. Customer and Provider agree to the exclusive
jurisdiction of the courts of Florida for any action or proceeding arising out
of or in relation to this Agreement. This Agreement may be executed in
counterparts, each counterpart shall be deemed to be an original and all
counterparts individually or together shall constitute on and the same
instrument.

          7.   No partnership, agency or joint venture is intended or created by
this Agreement.
