Press Release Summary: Rotoblock\'s (OTCBB: ROTB) $25 Million Acquisition of China\'s
Hikom Gottell Targets Global Market for Energy Efficient and Environmental Equipment
Manufacturing

Press Release Body: SAN FRANCISCO & NANJING, China - Engine technology firm
Rotoblock Corp. (OTCBB: ROTB) and Nanjing\'s Hikom Gottell announce joint plans to
open a modern manufacturing facility that will produce advanced energy efficient and
environmental machinery and equipment, including small engines, heat pumps and
air-conditioning for global markets.

Last week, Rotoblock announced an agreement to purchase controlling interest in
Hikom Gottell for US$25 Million ($25,000,000). Rotoblock will purchase the hard
assets of Hikom Gottell\'s 10-acre manufacturing complex in Nanjing, its land,
factories, manufacturing equipment, testing facilities and delivery trucks as well
as the name Hikom Gottell and its distribution network.

\"We intend to market Hikom Gottell\'s current and future product lines globally under
the Rotoblock name,\" said CEO Mr. Chin Chih Liu. \"Working together I believe we can
expand the business and enter new markets.\"

Mr. Liu also noted, \"The household central air conditioning units are a
new-generation of products manufactured by Hikom Gottell. With intelligent and
flexible controls, this line meets a new standard of efficiency, comfort, and
safety, while bringing the enjoyment of central air conditioning. Small, quiet, and
convenient, these units are ideal for stores, offices, hotels, hospitals, shopping
malls, restaurants and entertainment venues.\"

Ground source heat pump central air-conditioner systems are also one of the main
products provided of Hikom Gottell. The system, through its advanced heat pump
units, changes low level heat energy absorbed from solar energy, then contained in
the soil, ground water, and surface water (such as water in rivers, lakes, and seas)
into utilizable high level heat energy which is supplied to buildings for cooling or
heating purposes.

According to Mr. Liu, \"Hikom Gottell has developed a reputation as a leader in
air-conditioning and heat pumps with its nationwide sales network and quality
assurance after-market support. These products, many of which are developed
independently, have all earned international certifications of quality, including
the \'Famous Chinese Brand with Perfect Quality\' distinction among its peer
companies. By doing this, Hikom Gottell has earned many respected customers
throughout China.\"
