Altira extends its leadership role in alternative fuel investing by funding transportable nuclear power manufacturer Hyperion Power Generation


Denver, CO., April 16, 2008 — Altira Group LLC, the pioneer and leader in venture capital and
private equity funding for energy technology companies announced today an investment in Hyperion
Power Generation, Inc. (HPG), of Santa Fe, New Mexico. HPG is developing a new type of small, self-
contained, transportable nuclear power reactor to produce heat, steam and electricity for a variety of
commercial applications that require reliable power independent of the common grid.

Altiras investment in HPG was made out of the recently closed Altira Technology Fund
V — a $176 Million fund focused on venture capital for energy technologies.

Hyperion Power Generation (beta.gen4energy.com) has licensed
technology from the Los Alamos National Laboratory (LANL). Under the Technology
Transfer Program, HPG has the commercialization rights to introduce, license,
manufacture, market and distribute the reactor invented at LANL.

About 4,000 units of the initial design will be manufactured at a new U.S. site yet to be
determined. The initial rector will be a compact, self-regulating, self-contained design
with no moving parts and about the size of a hot tub. Sealed at the factory, the module is
not opened until it is time for the unit to be refueled at the factory approximately
every five years or so. This helps guard against tampering.

Since it is portable, the reactor can be deployed virtually anywhere power is needed —
remote industrial operations such as the Alberta oil sands, military installations or
communities looking to supplement grid-supplied power. Once deployed, the Hyperion
module delivers approximately 70 megawatts (MW) of heat (thermal energy) and 25
megawatts (MW) of electrical power via steam turbine. This is enough power to provide
electricity for a community of 20,000 average-sized, American-style homes. Hyperion
modules can also be “ganged” to provide even more power.

“For over a decade Altira has been committed to providing equity capital for the energy
world of the future,” said Peter Edwards, partner at Altira and a board member of
Hyperion Power Generation. “We look to partner with companies who are developing
transformative technology to meet increasing global demand. HPGs technology will
have a prominent role in the energy world of the future, providing a safe, compact, near-
zero-emission, waste-efficient source for thermal and electrical energy.”

“We are excited to have Altira as a partner, said John R. (Grizz) Deal, President and
CEO of Hyperion Power Generation. “They are a seasoned investment firm with a good
track record of partnering with companies and achieving success. This investment will
help us reach our vision of bringing the benefits of nuclear power to locations where the
option was never available before. Its also a big opportunity to create new jobs and
assist the U.S. in securing its position as a leader in the quest for clean energy.”
