Rental fees for international long distance leased line rental fees are generally based on transmission speed and distance. 

We continue to experience a decline in rental fees for all of our leased line products. The decline in rental fees since 2000 has been substantial, particularly for international leased lines, partly as a result of competition from new international leased line service providers. In response, we continue to implement marketing and service campaigns to retain our high-value corporate customers. 

## International Data Services 

Our international data services include international IP VPN services and Taiwan internet gateway services. Total revenues for international data services were NT$0.7 billion, NT$0.8 billion and NT$1.0 billion (US$35.8 million) for 2008, 2009, 2010 respectively. Due to growth of the international corporations in Taiwan, we expect demand for IP VPN and Taiwan internet gateway services to continue to increase and our revenues from our international data services to continue to grow. 

## Satellite Services 

We are a 50% owner of the ST-1 telecommunications satellite. Singapore Telecommunications Ltd. owns the remaining 50%. ST-1 was launched on August 26, 1998 and began commercial operations on December 1, 1998. We lease out transponder capacity on ST-1 and provide satellite lease circuits. In addition, we have two satellite communication centers that enable us to provide satellite value-added services and backup systems for use in major emergencies. We also provide satellite services to Southeast Asia. We are currently constructing the ST-2 telecommunications satellite together with Singapore Telecommunications Ltd. and plan to launch this satellite by the second quarter of 2011. We expect to retire the ST-1 telecommunications satellite after the launch of the ST-2 telecommunications satellite. 

Chunghwa entered into a contract with ST-2 Satellite Ventures Pte., Ltd. on March 12, 2010 to lease capacity on the ST-2 satellite. The lease term is 15 years starting from the official start of operations of the ST-2 satellite, and the total contract value is approximately NT$6.0 billion (US$187.8 million). We have already prepaid NT$2.5 billion (US$86.4 million), which was classified as other assets – others. As of December 31, 2010, the ST-2 satellite is still under construction.
