THE OFFER EXPIRES AT 12:00 MIDNIGHT EASTERN TIME ON OCTOBER 20, 2000, UNLESS

    Neither the Fund nor its Board of Directors nor Credit Suisse Asset
Management, LLC (the Fund's investment advisor) is making any recommendation to
any holder of Shares as to whether to tender Shares. Each shareholder is urged
to consult the shareholder's own investment and tax advisors before deciding
whether to tender Shares. If, after considering the Offer to Purchase and Letter
of Transmittal, you wish to tender your Shares pursuant to the Offer, if you are
the record owner of Shares, you should follow the instructions contained in the
Offer to Purchase and Letter of Transmittal, and, if the Shares are held of
record in the name of a broker, dealer, commercial bank, trust company or other
nominee, you should contact that firm to effect the tender for you.

    Your attention is called to the following:

     1. Unless extended, the Offer and withdrawal rights expire at 5:00 P.M.
        Eastern Time on October 20, 2000.

     2. The Offer is subject to certain conditions set forth in the Offer to
        Purchase. Under certain circumstances, the Fund will not be required to
        accept for payment, purchase or pay for any Shares tendered, and the
        Fund may also amend, extend or terminate the Offer.

     3. If more than 3,125,120 Shares are duly tendered (and not timely
        withdrawn), the Fund will purchase Shares from tendering shareholders,
        in accordance with the terms and subject to the conditions specified in
        the Offer to Purchase, on a pro rata basis (disregarding fractions) in
        accordance with the number of Shares duly tendered by each shareholder
        during the period the Offer is open (and not timely withdrawn), unless
        the Fund determines not to purchase any Shares.

    The Offer is not being made to (nor will tenders be accepted from or on
behalf of) holders of Shares in any jurisdiction in which the Offer or its
acceptance would violate the laws of such jurisdiction. In any jurisdiction
where the securities, blue sky or other laws require the Offer to be made by a
licensed broker or dealer, the Offer shall be deemed to be made on behalf of the
Fund by one or more registered brokers or dealers licensed under the laws of
that jurisdiction.

    Should you have any other questions concerning the enclosed material, please
contact your broker, dealer, commercial bank, trust company or other nominee, or
call the Depositary at the number indicated in the Offer to Purchase.

                                          Very truly yours,

                                          The Latin America Investment Fund,
                                          Inc.
