PART III

ITEM 10.  DIRECTORS AND EXECUTIVE OFFICERS OF THE REGISTRANT

         The information required by Item 10 regarding directors and executive
officers of the Company is included in the "Directors and Executive Officers of
the Company" section of Part I, except that information regarding compliance
with Section 16(a) of the Exchange Act is set forth below.

         Section 16(a) of the Exchange Act requires the Company's officers and
directors, and persons who own more than 10% of the Company's Common Stock, to
file with the Securities and Exchange Commission reports of ownership and
changes in ownership and to provide copies of such reports to the Company and to
the NASDAQ Stock Market. Based solely on a review of the copies of such reports
furnished to the Company, or written representations that no reports on Form 5

beneficial owners complied with all Section 16(a) filing requirements during

Compensation of Directors

         Directors do not receive cash compensation in connection with their
duties as directors, but may be reimbursed for expenses incurred by them in
connection with their services as directors.

         The Company grants stock options under our Directors Stock Option Plan
to each director who is not an IFX employee and who is not a beneficial owner of
5% or more of the Company's Common Stock (as determined in accordance with Rule
13d-3 of the Securities Exchange Act of 1934). Under this plan, we grant each
non-employee director an option to buy 450 shares of our Common Stock when the
director is first elected and an option to buy an additional 450 shares of
Common Stock at each annual meeting until he or she is no longer a director. If
a director serves on a committee of the board, he or she is granted an
additional option to buy 75 shares for each year of service. The exercise price
for the options is equal to 100% of the fair market value of our Common Stock on
the date of grant. The options cannot be exercised until six months after the
date of grant. Each option terminates on the earlier of a director's termination
for cause, one year after a director's death, or ten years from the date of
grant. During the fiscal year ended June 30, 2002, the directors received
options as follows:

                   Director        Amount     Exercise Price      Date Granted
                   --------        ------     --------------      ------------

          Patrick Delhougne         450           $0.80         December 7, 2001

         Mr. Eidelstein and Mr. Shalom, as employees, and Richard Capone, George
Duarte, Charles Delaney (director until June 2002), Charles Moore (director
until June 2002), and Mark Lama, as 5% or more beneficial owners, did not
receive any options under this plan.

                                        4

<PAGE>

the number of whole and fractional years remaining until the end of the
employment agreement's term multiplied by three times his annualized current
salary and highest previous annual bonus. The agreement prohibits Mr. Eidelstein
from disclosing confidential information regarding the Company, and during the
period of his employment with the Company and for one year thereafter, being
involved in any capacity with any business competitive with the Company in the
United States, Latin America or in any other market in which the Company is then

         Mr. Shalom serves as the Chief Executive Officer of the Company for a

salary plus bonus for the prior year. If Mr. Shalom is terminated within two
years after a "Change of Control", he receives an amount equal to the product of
the number of whole and fractional years remaining until the end of the
employment agreement's term multiplied by three times his annualized current
salary and highest previous annual bonus. The agreement prohibits Mr. Shalom
from disclosing confidential information regarding the Company, and during the
period of his employment with the Company and for one year thereafter being

         Jose Leiman serves as the General Counsel (and served as Chief
Financial Officer until July 31, 2002) pursuant to a two-year employment
agreement which commenced on May 7, 2001. The term of the employment agreement
is subject to automatic extension unless notified otherwise by either the
Company or Mr. Leiman. Mr. Leiman's base salary is $235,000 per year for the

the employment agreement's term multiplied by his annualized current salary plus
bonus for the prior year. If Mr. Leiman is terminated within two years after a
"Change of Control" (as defined in the employment agreement), he receives an
amount equal to the product of the number of whole and fractional years
remaining until the end of the employment agreement's term multiplied by three
times his annualized current salary and highest previous annual bonus. The
agreement prohibits Mr. Leiman from disclosing confidential information
regarding the Company, and during the period of his employment with the Company
and for one year thereafter from being involved in any capacity with any
business competitive with the Company in the United States, Latin America or in
any other market in which the Company is then conducting business.

         Under the agreements of Messrs. Eidelstein, Shalom and Leiman, a
"Change in Control" means the occurrence of any one of the following events: (a)

of IFX will be controlled by another corporation; (b) any sale, lease, exchange
or transfer (in one transaction or series of related transactions) of all or

of the Securities Exchange Act of 1934), or two or more persons acting in
concert, of beneficial ownership (within the meaning of Rule 13d-3 promulgated
under the Exchange Act) of 50% or more of the outstanding shares of voting stock
of IFX; provided, however, that for purposes of the foregoing, "person" excludes
UBS Capital Americas III, L.P., UBS Capital LLC, Lee S. Casty, the Casty
Grantor Subtrust, International Technology Investments, LC or any of their
affiliates, any

                                        5

underwriter purchasing shares of IFX with the intent of reselling them, or (e)
if, during any period of 24 consecutive calendar months commencing on the date
of these agreements, those individuals (the "Continuing Directors") who either
(i) were directors of IFX on the first day of each such period, or (ii)
subsequently became directors of IFX and whose actual election or initial
nomination for election subsequent to that date was approved by a majority of
the Continuing Directors then on the board of directors of IFX, cease to

ITEM 13.  CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

         Index Futures Group, Inc., a wholly-owned subsidiary of the
Company, and LC Management, Inc., a corporation controlled by Lee S. Casty, who
owns more than 5% of IFX, have entered into an Amended and Restated Consulting
Agreement dated as of July 1, 2002. Under the terms of the Consulting Agreement,
Mr. Casty is available to provide consulting services regarding operational
matters of IFX and its affiliates for a fee of $5,000 per month. Such consulting
services include attendance once each quarter at a two-day meeting with IFX
management in Miami, Florida. Mr. Casty is responsible for his own travel
expenses. The Consulting Agreement may be terminated by either party on at least
30 days notice after June 1, 2003.

         The INTCOMEX Group ("INTCOMEX") is a group of companies which is a
Latin American wholesale distributor of microcomputers, networking products,
mass storage products, multimedia products, computer peripheral equipment and
computer components. INTCOMEX is owned by family members of Michael Shalom, the
Company's Chief Executive Officer and a director. Mr. Shalom was a principal of
INTCOMEX until July 1999. During fiscal year 2002, IFX sold connectivity
services for approximately $55,200 to INTCOMEX and purchased equipment from
INTCOMEX at a cost of approximately $225,400.

         Joel M. Eidelstein, the President and a director of the Company, has
received loans for personal expenses from the Company and Tutopia.com, Inc. (of
which IFX owns approximately a 44% interest on an "as converted" basis, assuming
the outstanding preferred stock of Tutopia was converted to common stock),
pursuant to two promissory notes to the Company and two promissory notes to
Tutopia. The promissory notes to the Company in the amount of $20,000 and
$10,000 were made on August 4, 1999 and November 4, 1999, respectively. Interest
in the amount of 5% per annum, compounds monthly, from the date of each note.
Principal and interest on both notes was due on August 4, 2000. Any principal or
interest not paid when due bears interest at the rate of 8% per annum. The
promissory notes to Tutopia, each in the amount of $15,000, were made on January
22, 2001 and September 11, 2001. The January 22, 2001 note to Tutopia accrues
interest at a rate of 5% per annum from the date of the note and any amount not
paid when due bears interest at a rate of 10% per annum. Interest on the January
22, 2001 note was payable semi-annually beginning on July 22, 2001. All
principal and interest was due on January 22, 2002. The September 11, 2001 note
to Tutopia accrues interest at a rate of 5% per annum from the date of the note
and any amount not paid when due bears interest at a rate of 15% per annum. All
outstanding principal and interest was due on September 11, 2002. As of
September 30, 2002, Mr. Eidelstein owed $37,100 in principal and interest to the
Company and $32,800 in principal and interest to Tutopia, the largest amount
outstanding on such loans since they were made.

         On an as converted basis at June 30, 2002, UBS owned approximately 63%
of the Company and approximately 37% of Tutopia. Mr. Capone and Mr. Duarte are
partners and Mr. Lama is a principal of UBS Capital Americas, LLC, an affiliate
of UBS. Since Mr. Capone, Mr. Duarte and Mr. Lama (and Mr. Delaney and Mr. Moore
until June 2002) have an investment interest in UBS, they may benefit from
transactions between UBS on the one hand and IFX and its subsidiaries on the
other. Sales to Tutopia accounted for 25.6% of the Company's total revenues for
fiscal year 2002. On February 19, 2002, UBS invested $7 million of cash and
surrendered 1.5 million shares of IFX's common stock held by UBS in exchange for
approximately 3.8 million shares of IFX Series C Convertible Preferred Stock. On
June 28, 2002, UBS, International Technology Investments, LC ("ITI"), LSC, LLC
("LSC"), and Jak Bursztyn ("Bursztyn"), the President of Tutopia, invested a
total of $5 million and surrendered shares of IFX's preferred stock and common
stock in exchange for 6,432,608 shares of IFX's Series D Convertible Preferred
Stock ("Series D Preferred Stock"). ITI is an affiliate of Michael Shalom and
LSC is an affiliate of Lee S. Casty. In this transaction, UBS invested
approximately $3.33 million in cash and surrendered 750,000 shares of Series C
Preferred Stock in exchange for 4,652,778 shares of Series D Preferred Stock.
Each of ITI and LSC invested approximately $812,500 in cash and surrendered
approximately 333,000 shares of common stock in exchange for 843,808 shares of
Series D Preferred Stock. Mr. Bursztyn invested approximately $47,000 in cash
and surrendered approximately 10,000 shares of common stock in exchange for
approximately 43,273 shares of Series D Preferred Stock.
