FINANCIAL RESOURCES OF MANDARIN FOR THE AGREEMENTS

On 9th September, 2005, PCCW Services Limited, an indirect wholly-owned subsidiary of PCCW, entered into a facility agreement on normal commercial terms with Mandarin, which amount is sufficient to pay the consideration payable under all three agreements.

Accordingly, Mandarin has the necessary financial resources available to it under the above facilities to pay the consideration under each of the agreements.

SECURITY/GUARANTEES

No security or guarantee has been given by the Company as part of, or in connection with, the entering into of any of the agreements referred to above or the respective transactions contemplated by them.

REASONS FOR, AND BENEFITS TO, THE GROUP

To compete more effectively in the 2G mobile telecommunications services market, the Group considers it desirable to upgrade Mandarin's 2G Network to provide more advanced features and enhance network quality and to increase its capacity. Accordingly, Mandarin has entered into the agreements with Nortel to purchase certain equipment, software and services to upgrade the infrastructure systems and enhance the coverage and quality of Mandarin's 2G Network.

The Directors believe that the terms of the agreements are fair and reasonable and in the interests of the Company and its shareholders as a whole.

INFORMATION ABOUT THE GROUP AND NORTEL

The Group is a developer and provider of wireless communications and data services in Hong Kong, holding both the 2G Licence and the 3G Licence.

Nortel delivers innovative technology solutions encompassing end-to-end broadband, Voice over IP, multimedia services and applications, and wireless broadband designed to help people solve the world's greatest challenges.

To the best of the Directors' knowledge, information and belief, after having made all reasonable enquiries, Nortel and the ultimate beneficial owner of Nortel are third parties independent of the Company and the connected persons of the Company.

LETTER FROM THE BOARD

FINANCIAL EFFECTS

It is expected that the total assets and total liabilities of the Group would be increased upon completion of the agreements since the purchase of the equipment is to be funded by loan. The Directors believe that the immediate effect on the earnings of the Group currently cannot be ascertained as it will depend on the incremental revenue derived from the upgraded 2G Network.

LISTING RULES IMPLICATIONS

The consideration payable under the agreements in aggregate is an amount of US$16,500,000 (HK$128,700,000). Accordingly, pursuant to Chapter 14 of the Listing Rules, the agreements when aggregated constitute a discloseable transaction for the Company.

FURTHER INFORMATION

Your attention is drawn to the information set out in the Appendix to this circular.

Yours faithfully,

By Order of the Board

SUNDAY COMMUNICATIONS LIMITED
