      This letter sets forth the terms of our agreement (this "Agreement") with
respect to your separation from employment with StarMedia Network, Inc. and its

President and Vice 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 and 2000 StarMedia Stock Option Plans,

except as otherwise provided 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:

      (a)   You will resign from your position as Vice Chairman of the Board
            of Directors of StarMedia effective as of the Separation Date.
            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.  You will resign as a
            member of the Board of Directors on or before December 31, 2001.
            StarMedia will pay any and all reasonable expenses incurred by
            you in connection with your service as a Director of the
            Company.  You will not receive any additional remuneration for
            service in that capacity.

      (b)   Until December 31, 2001, 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 mutually acceptable to you and StarMedia. However, after the
            Separation Date you will not be entitled to maintain an office at
            StarMedia.

      (c)   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 taxes and other legally
            required withholding amounts on or before August 9, 2001. Payment
            will be deemed made on the date you receive it.

      (d)   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 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.  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 coverage 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.

      (e)   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

            effect in accordance with its terms ("The Line of Credit").

including claims for compensation, bonuses, severance pay, stock options, tax
indemnity and all claims arising from your employment with StarMedia, whether

officer or director pursuant to Section VIII of the Amended and Restated
Certificate of Incorporation and/or Section 21 of the Employment Agreement,

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
