Through DBA agreement with Jiahong, Largo Vista is engaged in the business of purchasing and reselling liquid petroleum gas ("LPG") in the retail and wholesale markets to both residential and commercial consumers. Largo Vista operated a storage depot and has an office headquarters in the City of Zunyi. Largo Vista has found the storage depot operations to be unprofitable, and therefore has terminated those operations in order to concentrate its resources on supplying LPG in bottles and through pipelines.

In February 2002, Largo Vista's China operations entered into an agreement with the Zunyi Municipal Government to design and install LPG pipeline systems in residential areas in the city of Zunyi. In exchange for installing the pipeline, the agreement provides for the Largo Vista to be the sole LPG supplier for those households for 40 years. Largo Vista substantially completed the installation of the LPG pipeline in 2002 and continues to operate the pipeline.

In May 2003, Largo Vista's China operations entered into its second agreement with Zunyi Municipal Government to design and install more LPG pipeline systems in residential areas in the city of Zunyi, China. The pipeline project was substantially completed in December of 2004. These two pipelines currently serve approximately 720 customers. When natural gas becomes available to the area, these pipelines will be in place to deliver that commodity to the same customers.
