      Re:  SEPARATION AGREEMENT INCLUDING A GENERAL RELEASE

Dear Fernando:

      This letter sets forth the terms of our agreement (this "Agreement") with
respect to your separation from employment with StarMedia Network, Inc. and its
subsidiaries (collectively, "StarMedia"), and the end of your tenure as Chief
Executive Officer and Chairman of the Board of StarMedia.

      1. Your final date of employment with StarMedia will be August 7, 2001
(the "Separation Date"). As of the Separation Date, except as specifically
provided in this Agreement, all compensation, including bonuses, and all other
benefits and perquisites of employment with StarMedia, including the vesting of
Stock Options pursuant to the 1997, 1998, 1999 and 2000 StarMedia Stock Option
Plans, will cease. As of the Separation Date, all of StarMedia's and your
obligations, except as otherwise provided in this Agreement, under the
Employment Agreement dated as of December 28, 2000 (the "Employment Agreement"),
between you and StarMedia, will cease.

      If the terms of this Agreement are accepted by you and if you return a
fully executed original of this Agreement as described below you will be
entitled to the following:

      You may remain Chairman of the Board of Directors of StarMedia until
November 7, 2001. During the period that you are Chairman (the "Transition
Period"), you agree to the following:

<Page>

Page 2

            o    You will only speak about StarMedia in StarMedia scheduled
                 and managed interviews or at public speaking events, other
                 than to respond to questions asked of you. During StarMedia
                 scheduled and managed interviews and public speaking events,
                 ("StarMedia venues"), you will limit your statements to
                 pre-written and pre-approved messages and statements provided
                 by StarMedia ("the StarMedia messages"). In the event you are
                 asked questions about StarMedia during non-StarMedia venues,
                 you agree to keep your comments to the StarMedia messages.
                 If StarMedia receives press inquiries directed at you
                 personally and not in your capacity as a representative of
                 StarMedia, StarMedia agrees to refer such inquiries to you;

            o    You understand and agree that you are not entitled or
                 authorized to and thus agree that you will not commit
                 StarMedia to any business opportunities.

            o    StarMedia will make available to you your current office for
                 your use during the Transition Period to conduct StarMedia
                 business. StarMedia will provide to you limited and reasonable
                 administrative support from the staff of StarMedia and
                 maintain for you an e-mail account on StarMedia's server and
                 voicemail at your former extension which will contain an
                 outgoing message acceptable to you and StarMedia. However,
                 after the Transition Period you will not be entitled to
                 maintain an office at StarMedia nor entitled to any further
                 administrative support or any other services.

      (b)   On or before November 7, 2001, you agree that you will resign from
            your position as Chairman of the Board of Directors of StarMedia.
            You will not receive any additional remuneration for service in
            that capacity. You may remain a member of the Board of Directors.

      (c)   On or before the Separation Date, StarMedia will pay you any unpaid
            salary through the Separation Date and all reasonable unpaid
            expenses incurred by you in connection with service to the Company
            on or prior to the Separation Date. StarMedia will pay any and all
            reasonable expenses incurred by you in connection with your service
            as Chairman of the Board during the Transition Period or thereafter
            as a Director of the Company.

      (d)   StarMedia will pay you, via wire transfer to an account designated
            by you, a one time payment in the amount of Six Hundred and
            Fifty-Thousand Dollars ($650,000.00), less applicable taxes and
            other legally required withholding amounts within two days of the
            Separation Date. Payment will be deemed made on the date you receive
            it.

      (e)   In addition, in the event that you elect COBRA coverage, for the
            initial eighteen (18) months of the period provided pursuant to
            COBRA, commencing on

<Page>

Page 3

            September 1, 2001 and ending February 28, 2003, StarMedia will pay
            the applicable COBRA premiums on your behalf (including your
            immediate family). As of March 1, 2003, you will be solely
            responsible for all applicable COBRA premiums. In addition,
            commencing on September 1, 2001 and ending February 28, 2003,
            StarMedia will pay all applicable premiums on your behalf (including
            your immediate family) to continue StarMedia's dental and vision
            coverage on the same terms as active employees of StarMedia to the
            extent such plans allow for continuation coverage. StarMedia
            reserves the right to alter and amend its benefit plans at any time.
            Your entitlement to COBRA continuation coverage paid for by
            StarMedia shall cease if comparable coverage is made available to
            you and your immediate family through your employment or your
            spouse's employment or if the COBRA continuation period ends sooner
            as provided in Section 4980(B) of the Internal Revenue Code of 1986
            as amended. Likewise, your entitlement to continued dental or vision
            coverage shall cease if comparable dental or vision coverage is made
            available to you and your immediate family through your employment
            or your spouse's employment.

      (f)   The Line of Credit provided pursuant to the letter agreement dated
            December 28, 2000 between you and StarMedia, as amended and restated
            by the letter agreement dated January 31, 2001, will remain in full
            force and effect in accordance with its terms ("The Line of
            Credit").

      2.    You and StarMedia agree to the following General Release:

            (a) In return for the payments and other benefits described above as
well as the mutual promises contained herein, you completely release StarMedia
from all claims, other than the Excluded Claims as defined below, of any kind,
known and unknown, which you may now have or have ever had against StarMedia,
including claims for compensation, bonuses, severance pay, stock options, tax
indemnity and all claims arising from your employment with StarMedia, whether
based on contract, tort, statute, local or municipal ordinance, regulation or
any comparable law in any jurisdiction ("Released Claims"). By way of example
and not in limitation, the Released Claims shall include any claims arising
under Title VII of the Civil Rights Act of 1964, as amended, the Americans with
Disabilities Act, and the New York Human Rights Law, as well as any claims
asserting wrongful termination, breach of contract, negligent or intentional
infliction of emotional distress, negligent or intentional misrepresentation,
negligent or intentional interference with contract, and defamation.

            As used in this paragraph (a), the term "Excluded Claims" means (i)
any and all claims for indemnification or insurance claims, including without
limitation claims under any of StarMedia's directors and officers liability
insurance policies, arising out of your service to StarMedia as an officer or
director pursuant to Section VIII of the Amended and Restated Certificate of
Incorporation and/or Section 21 of the Employment Agreement, (ii) any claims

including without limitation claims arising out of this Agreement. StarMedia
reserves the right to amend and alter its directors and officers liability
insurance policies at any time, but in no event shall StarMedia reduce the
amount of such coverage for acts or omissions prior to the Separation Date.

            (b) You represent that you have not filed or permitted to be filed
on your behalf any claims, administrative proceedings or lawsuits against
StarMedia, and you agree that you will not do so at any time in the future with
respect to the subject matter of the Released Claims. Prior to December 31,
2001, you agree that you will not participate in or commence any election
contest as defined in Rule 14-11 of Regulation 14A of the Securities and
Exchange Act of 1934. If you violate this Agreement by instituting any such
claims, proceedings or lawsuits, you agree to pay all costs and expenses
incurred by StarMedia in defending against the claim, proceeding or lawsuit,
including its reasonable attorneys' fees, disbursements and costs.

            (c) StarMedia completely releases you from any and all claims,
causes of action, suits, proceedings, debts, accounts, accountings, demands,
liabilities, acts, omissions, and all other controversies of every type, kind,
nature, description and character whatsoever, whether known or unknown, foreseen
or unforeseen, liquidated or unliquidated, and whether based upon facts now
known or unknown, direct or derivative, in law, equity or bankruptcy, other than
the StarMedia Excluded Claims, arising at any time on or prior to the Separation
Date (collectively, the "StarMedia Released Claims").

            As used in this paragraph (c), the term "StarMedia Excluded Claims"
means any claims under the Line of Credit.

            (d) StarMedia represents that it has not filed or permitted to be
filed on its behalf any claims, administrative proceedings or lawsuits against
you, and it agrees that it will not do so at any time in the future with respect
to the subject matter of the StarMedia Released Claims. If StarMedia violates
this Agreement by instituting any such claims, proceedings or lawsuits,
StarMedia agrees to pay all costs and expenses incurred by you in defending
against the claim, proceeding or lawsuit, including your reasonable attorneys'
fees, disbursements and costs.

      3.    Other than as provided in this Agreement, you understand and agree
that you are not entitled to any additional severance, loan forgiveness and tax
indemnity from StarMedia as originally provided under any agreement with
StarMedia. You agree that you will not borrow any additional money under any
agreement with StarMedia.

      4.    You hereby represent and warrant to StarMedia that:

            (a) As of the Separation Date, you were and are the record and
beneficial owner of the Collateral, as such term is defined in the Line of
Credit, free and clear of all liens, charges, pledges, encumbrances,

default under any such indenture, agreement or other instrument, or result in
the creation or imposition of any Lien of any nature whatsoever upon any of your
properties or assets.

            (c) There is no action, suit, investigation or proceeding pending
or, to your knowledge, threatened against or affecting you before any court or
arbitrator or any governmental body which in any manner relates to your
ownership of the Collateral.

            (d) This Agreement has been duly executed and delivered by you and

further agree not to engage in any Disparagement to anyone regarding StarMedia
or its technical abilities, product plans, market plans, state of development,

aware of this Agreement, become aware.

      7.    You and the Board of Directors agree to characterize your separation
from employment as a resignation in order for you to pursue other interests. You
and the Board of Directors will approve, in writing, language for any press
release or public statement regarding your separation. Each Party may withhold
such approval in its sole discretion.

      8.    You understand and acknowledge that as of the last day of the
Transition Period, you are not authorized to represent StarMedia or to hold
yourself out as an employee or representative of StarMedia. You further agree to
refer all strategic inquiries regarding StarMedia to the Chief Executive Officer
of StarMedia.

      9.    You represent that you have returned to StarMedia, all Company
