APPOINTMENT OF THE CHAIRMAN OF THE EGM

The Board of Directors of Millicom proposes to appoint Mr. Jean-Michel
Schmit, a Partner at the law firm Nautadutilh Avocats Luxembourg, to
chair the EGM and to authorise him to elect a Secretary and a Scrutineer
of the EGM.

DIVIDEND PAYMENT

On a parent company basis, Millicom generated a profit of USD
623,392,030 for the year ended December 31, 2010. Of this amount, the
shareholders decided at the Annual General Meeting held on May 31, 2011
to allocate USD 60,719 to the legal reserve in accordance with the
requirements of the Luxembourg Law on commercial companies dated August
10, 1915, as amended (the "1915 Law"), to distribute as a dividend USD
188,111,642 and to carry forward the remaining part of the profit of USD
435,219,669.

At the December 2, 2011 EGM, the shareholders of Millicom will vote on
the resolution to distribute a per share gross cash dividend of USD 3 to
the shareholders in the manner provided in Article 21 and Article 23 of
the Articles.

The financial statements of Millicom as of December 31, 2010 drawn up by
Millicom's Board of Directors (the “2010 Financial Statements”) show
that Millicom has sufficient funds available, in accordance with
applicable law, to distribute the proposed USD 3 dividend per share
which represents an aggregate dividend of approximately USD 308,000,000.
The proposed dividend shall be paid out of the available carried forward
profits.

In accordance with Luxembourg income tax law, the payment of dividend to
the shareholders holding less than 10% of the share capital will be
subject to a 15% withholding tax. Millicom will withhold the 15%
withholding tax and pay this amount to the Luxembourg tax
administration. The dividend will be paid net of withholding tax. A
reduced withholding tax rate may be foreseen in a double tax treaty
concluded between Luxembourg and the country of residence of the
shareholder or an exemption may be available in case the Luxembourg
withholding tax exemption regime conditions are fulfilled. Shareholders
should contact their advisors regarding the procedure and the deadline
for a potential refund of the withholding tax from the Luxembourg tax
administration.

Eligible Millicom shareholders will receive their dividends in USD
(United States Dollars) whereas holders of Swedish Depository Receipts
(SDRs) will be paid exclusively in SEK (Swedish crowns). Millicom shall
arrange for a conversion of the dividend from USD to SEK. Such
conversion shall be effected at a market rate of exchange, no earlier
than eight and no later than two banking days before the payment date,
or the day on which the funds are made available to Euroclear Sweden AB
(Euroclear). The applicable rate of exchange shall be the rate of
exchange obtained through the combination of all foreign exchange
conversions.

The dividend will be paid to shareholders and SDR holders who are
registered in the shareholders and SDR registries kept by Millicom,
Euroclear or American Stock Transfer & Trust Company (AST) as of
December 7, 2011 (the “Dividend Payment Record Date”).
