SUPPLEMENTAL NOTICE OF ANNUAL GENERAL MEETING

Reference is made to the notice (the ''Initial Notice'') of annual general meeting (''AGM'') dated 27 April 2021, by which AsiaInfo Technologies Limited (the ''Company'') convenes the AGM to be held at AsiaInfo Plaza, Dong Qu, 10 Xibeiwang Dong Lu, Haidian District, Beijing, PRC on Friday, 28 May 2021 at 10 a.m. and this supplemental notice shall be read together with the Initial Notice.

THIS SUPPLEMENTAL NOTICE IS HEREBY GIVEN that the following proposed resolution will be considered and, if thought fit, approved (with or without modification) by shareholders of the Company at the AGM, in addition to the proposed resolutions set out in the Initial Notice:

6. ''THAT subject to and conditional upon the Listing Committee of The Stock Exchange of Hong Kong Limited granting listing of, and permission to deal in, the Shares to be issued upon the exercise of share options which may be granted under the Company's share option scheme adopted by the Company on 25 November 2019 (the ''2019 Share Option Scheme''), the existing scheme mandate limit in respect of the granting of share options to subscribe for Shares under the 2019 Share Option Scheme be refreshed and renewed so that the total number of Shares which may be allotted and issued pursuant to the grant and exercise of the share options under the 2019 Share Option Scheme and any other share option schemes of the Company shall not exceed 10% of the total number of Shares in issue as at the date of passing of this resolution (the ''Refreshed Limit'') and that the Directors be and are hereby authorized, subject to compliance with the Listing Rules, to grant share options under the 2019 Share Option Scheme up to the Refreshed Limit and to exercise all

- 1 -

the powers of the Company to allot, issue and deal with Shares pursuant to the exercise of such options and to do such acts and execute such documents for or incidental to such purpose.''

By Order of the Board

AsiaInfo Technologies Limited

Dr. TIAN Suning

Chairman of the Board and Executive Director

Hong Kong, 7 May 2021

Notes:

1. A shareholder entitled to attend and vote at the above meeting is entitled to appoint one or more proxies to attend, speak and vote in his/her stead. The proxy does not need to be a shareholder of the Company.
2. Where there are joint registered holders of any shares, any one of such persons may vote at the above meeting (or at any adjournment of it), either personally or by proxy, in respect of such shares as if he/she were solely entitled thereto but the vote of the senior holder who tenders a vote, whether in person or by proxy, will be accepted to the exclusion of the vote(s) of the other joint holders and, for this purpose, seniority shall be determined by the order in which the names stand in the register of members of the Company in respect of the relevant joint holding.
3. Since the proxy form (the ''First Proxy Form'') sent together with the Initial Notice does not contain the proposed resolution for the refreshment of the scheme mandate limit of the 2019 Share Option Scheme set out in this supplemental notice, a new proxy form (the ''Second Proxy Form'') has been prepared and is sent together with the Company's supplemental circular of which this supplemental notice of AGM forms part.
4. Shareholders are requested to complete and return the Second Proxy Form in accordance with the instructions printed thereon to the Hong Kong share registrar of the Company, Computershare Hong Kong Investor Services Limited, at 17M Floor, Hopewell Centre, 183 Queen's Road East, Wan Chai, Hong Kong not less than 48 hours before the time appointed for holding the AGM or any adjournment thereof.
5. A shareholder who has not yet lodged the First Proxy Form with the Company is requested to lodge the Second Proxy Form if he/she wishes to appoint proxies to attend the AGM on his/her behalf. In this case, the First Proxy Form should not be lodged with the Company.
6. A shareholder who has already lodged the First Proxy Form with the Company should note that:
7. 1. if no Second Proxy Form is lodged with the Company, the First Proxy Form will be treated as a valid proxy form lodged by him/her if correctly completed. The proxy so appointed by the shareholder will be entitled to vote at his/her discretion or to abstain from voting on any resolution properly put to the AGM, including the resolution for, among other matters, the proposed refreshment of the scheme mandate limit of the 2019 Share Option Scheme, as set out in this supplemental notice of AGM;

- 2 -

1. 1. if the Second Proxy Form is lodged with the Company 48 hours prior to the time appointed for holding the AGM (the ''Closing Time''), the Second Proxy Form will revoke and supersede the First Proxy Form previously lodged by him/her. The Second Proxy Form will be treated as a valid proxy form lodged by the shareholder if correctly completed; and
   2. if the Second Proxy Form is lodged with the Company after the Closing Time, the Second Proxy Form will be invalid. However, it will revoke the First Proxy Form previously lodged by the shareholder, and any vote that may be cast by the purported proxy (whether appointed under the First Proxy Form or the Second Proxy Form) will not be counted in any poll which will be taken on a proposed resolution. Accordingly, shareholders are advised not to lodge the Second Proxy Form after the Closing Time. In such case, if such shareholders wish to vote at the AGM, they will have to attend in person and vote at the AGM themselves.
2. Shareholders are reminded that completion and delivery of the First Proxy Form and/or the Second Proxy Form will not preclude shareholders from attending and voting in person at the AGM or at any adjourned meeting should they so wish.
3. Shareholders are reminded to refer to other notes contained in the Initial Notice.

As at the date of this notice, the Board comprises:

Executive Directors:	Dr. TIAN Suning, Mr. DING Jian and Mr. GAO Nianshu
Non-executive Directors:	Mr. ZHANG Yichen, Mr. XIN Yuesheng,
	Mr. ZHANG Liyang, Mr. YANG Lin and Ms. LIU Hong
