1. OTHER EVENTS

    O2Micro International Limited today announced that it filed a registration
statement on Form F-3 with the United States Securities and Exchange Commission
for a public offering of a maximum of $115 million of the company's ordinary
shares, all of which are being offered by the company. The company proposes to
list the ordinary shares offered pursuant to the registration statement on The
Stock Exchange of Hong Kong Limited ("HKSE"). An application has been made to
the HKSE for the listing of, and permission to deal in, such ordinary shares.
There is no assurance whether or when such application will be approved. In
preparation for the proposed offering and Hong Kong listing, O2Micro proposes to
effect a share split and establish an American depositary receipt ("ADR")
program. The entire transaction described above is subject to shareholder
approval as described below and there is no assurance that the proposed
offering, the listing on the HKSE or the establishment of the ADR program will
ultimately be effected. The press release announcing the filing of the
registration statement is attached hereto as Exhibit 99.1.

     In connection with the proposed listing on the HKSE, our Board of Directors
has also called an extraordinary general meeting of shareholders to be held on
November 14, 2005 at the offices of Maples and Calder, Ugland House, South
Church Street, George Town, Grand Cayman, Cayman Islands at 3:00 pm local time.
The purpose of the extraordinary general meeting is to approve the following
proposals:

     Proposal I   To approve as a special resolution the adoption of Amended and
Restated Articles of Association for our company.

     Proposal II  To approve as an ordinary resolution, the following:

                  1.   The public offering of ordinary shares;

                  2.   The primary listing of ordinary shares on the HKSE;

                  3.   Adoption of the 2005 Share Option Plan and 2005 Share
                       Incentive Plan;

                  4.   Adoption of a general mandate (the "Sale Mandate") to
                       allot, issue and deal with such number of unissued
                       ordinary shares not exceeding the sum of (i) 20% of the
                       total nominal amount of the share capital of our company
                       in issue and to be issued; and (ii) the total amount of
                       the share capital of our company repurchased by us (if
                       any) pursuant to the repurchase mandate described below
                       following the grant of the Sale Mandate;

                  5.   Adoption of a general mandate to exercise all powers of
                       the company to repurchase such number of ordinary shares

                       company's outstanding classes of shares and the
                       implementation of an ADR  program with respect to all
                       ordinary shares quoted on Nasdaq with each ADS
                       representing 50 ordinary shares.
