Company represents that the shares issuable pursuant to the valid exercise of
the options listed above will be registered pursuant to a Form S-8 prior to
Employee's exercise of such options. In the event that Company breaches this
obligation and if Employee exercises options (including payment in full of the
exercise price) at a time when the underlying shares are not freely salable
because Company has not



filed the applicable Form S-8, Company shall be obligated to pay Employee the
excess, if any, between the average of the daily high and low of Company stock
on the date the Company receives the completed notice of exercise and the
average of the daily high and low on the first date that Employee can freely
sell the underlying shares by virtue of Form S-8 or otherwise. All payments made
hereunder shall be subject to customary withholding and other employment taxes
required by law.

     Article 2.  Employee hereby agrees and acknowledges that the above Payments
represent the only payments of any kind that he is entitled to receive from the
Company, or any other Company affiliate, subsidiary, officer, director, agent,
successor, assign, attorney or related company or person (hereinafter
collectively referred to as the "IFX Parties") in relation to the Services or to
any other service provided by the Employee (or any company or person related to
the Employee) to the IFX Parties.

     Article 3.  Consequently, Employee hereby totally releases and forever and
irrevocably discharges all and each of the IFX Parties from any and all claims,
actions, causes of action, grievances, suits, charges, or complaints of any kind
or nature whatsoever, that he ever had or now has, whether fixed or contingent,
liquidated or unliquidated, known or unknown, suspected or unsuspected, and
whether arising in tort, contract, statute, or equity, before any federal,
state, local, or private court, agency, arbitrator, mediator, or other entity,
regardless of the relief or remedy. Without limiting the generality of the
foregoing, it being the intention of the parties to make this Payment and
Release Agreement as broad and as general as the law permits, this Payment and
Release Agreement specifically includes any and all subject matter and claims
arising from any alleged violation by the IFX Parties under Rule 10b-5 of the
Securities Act of 1933, as amended (15 U.S.C. (S) 78j(b)); the Age
Discrimination in Employment Act of 1967, as amended; Title VII of the Civil
Rights Act of 1964, as amended; the Civil Rights Act of 1866, as amended by the

as amended; the Employee Retirement Income Security Act of 1974, as amended; the
Americans with Disabilities Act; the Family and Medical Leave Act; the Equal Pay
Act; Executive Order 11246; Executive Order 11141; and any other statutory
claim, employment or other contract or implied contract claims (including, but
not limited to, any claims arising under the Employment Agreement, or any stock
option agreement between the Company and Employee), or common law claim for
fraud, wrongful discharge, breach of an implied covenant of good faith and fair
dealing, defamation, or invasion of privacy arising out of or involving his
employment with the Company, the termination of his employment with the Company,
or involving any continuing effects of his employment with the Company or
termination of employment with the Company. Employee further acknowledges that
he is aware that statutes exist that render null and void releases and
discharges of any claims, rights, demands, liabilities, action and causes of
action which are unknown to the releasing or discharging party at the time of
execution of the release and discharge. Employee hereby expressly waives,
surrenders and agrees to forego any protection to which he would otherwise be
entitled by virtue of their existence. Further, Employee hereby waives any
legal, civil, criminal, administrative or any other type of action, whether
contractual, tort, legal or otherwise, that Employee (or any of his heirs,
successors, assigns or affiliates) may have against any of the IFX Parties

     Article 4.  Employee acknowledges and agrees that notwithstanding the
termination of the employment relationship, the provisions of the Employment
Agreement set forth in Attachment A hereto remain in full force and effect.

     Article 5.  Employee acknowledges and agrees that he has had the
opportunity to have this Release and Payment Agreement reviewed by the legal
counsel of his choice. This Release Agreement shall be governed by and construed
in accordance with the laws of the State of Florida, USA.

     Article 6.  This Release Agreement may be executed in one or more
counterparts, and by the different Parties hereto in separate counterparts, each
of which when executed shall be deemed to be an original but all of which taken
together shall constitute one and the same agreement.

     IN WITNESS WHEREOF, each of the Parties have executed this Release
Agreement or caused to be executed by its duly authorized officer or legal
representative, as of the date written above.

executive staff of Employer, whose duties will include the formulation and
execution of management policy. Employee, for and in consideration of the
payments, rights and benefits provided herein, agrees that so long as he is
employed by Employer and, if Employer terminates his employment for Cause or if
Employee voluntarily terminates his employment with Employer, for a period of
one (1) year thereafter, Employee shall not (i) work, (ii) assist, (iii) own any
interest, directly or indirectly and whether individually or as a joint
venturer, partner, member, officer, director, shareholder, consultant, employee
or otherwise, in or (iv) make a financial investment, whether in the form of
equity or debt, in any business that is directly or substantially competitive

Employer is terminated, with respect to Employer's clients or customers.

          (b) Notwithstanding the foregoing, nothing herein shall prohibit
Employee from holding five percent (5%) or less of any class of voting
securities of any entity whose equity securities are listed on a national
securities exchange or regularly traded in the over-the-counter market and for

Dealers Automated Quotation system.



          (c) Upon the termination of Employee's employment with Employer, and
for one (1) year thereafter, Employee shall immediately notify Employer of each

business of which is directly or indirectly, similar to or in competition with
the Business. The provisions of this Section 10 shall survive termination of
this Agreement for any reason.

          (d) Employee agrees that the restrictions contained in this Section 10
are reasonable as to time and geographic scope because of the nature of the
Business and Employee agrees, in particular, that the geographic scope of this
restriction is reasonable because companies in the same industry as the

in direct competition with all other companies that provide services and
products similar to Employer's products and services throughout the United
States, Latin America and other markets in which Employer may be conducting the

          (a) Employee acknowledges that Employer has invested substantial time
and effort in assembling its present staff of personnel. Employee agrees that so
long as he is employed by Employer and, if Employer terminates his employment
for Cause or if Employee voluntarily terminates his employment with Employer,
for a period of one (1) year thereafter, Employee shall not either directly or
indirectly employ, solicit for employment, or advise or recommend to any other
person that such other person employ or solicit for employment, any of
Employer's employees.

          (b) Employee acknowledges that all customers of Employer, which
Employee has serviced or hereafter services during Employee's employment by
Employer and all prospective customers from whom Employee has solicited or may
solicit business while in the employ of Employer, shall be solely the customers
of Employer. Employee agrees that so long as he is employed by Employer and, if
Employer terminates his employment for Cause or if Employee voluntarily
terminates his employment with Employer, for a period of one (1) year
thereafter, Employee shall not either directly or indirectly solicit business,
as to products or services competitive with the Business of Employer, from any
of Employer's customers with whom Employee had contact during his employment
with Employer.

          (c) Employee agrees that so long as he is employed by Employer and, if
Employer terminates his employment for Cause or if Employee voluntarily
terminates his employment with Employer, for a period of one (1) year
thereafter, Employee shall not either directly or indirectly interfere with any
relationship between Employer and any of its suppliers, clients or employees.
Employee agrees that during such one (1) year period, he will not influence or
attempt to influence any of the customers or clients of Employer not to do
business with Employer.

          (d) Employee agrees that the restrictions contained in this Section 11
are reasonable as to time and geographic scope because of the nature of the
Business and Employee agrees, in particular, that the geographic scope of this
restriction is reasonable because companies in the same industry as the Business
compete on a nationwide basis. Employee acknowledges that Employer is in direct
competition with all other companies that provide services and products similar
to Employer's products and services on an outsourced basis throughout the United
States, Latin America and other markets in which Employer may be conducting the
Business at the time Employee's employment with Employer is terminated and,
because of the nature of the Business, Employee expressly agrees that the
covenants contained in this Section 11 cannot reasonably be limited to any
smaller geographic area.
