Debt financing in place
To date, $130 million of tax-exempt debt financing has been raised from institutional
lenders in support of construction of these projects.
Investors in the 2006 Texas bond issue purchased California bonds in September 2008
(Release of California and certain Texas bond proceeds remains subject to satisfaction of
certain performance and further financing conditions).
Tax-exempt debt financing required analysis by independent third-party experts.

prices
recognizing
“green”
value
of our gas to provide certainty of revenue streams.
Carbon credit revenue opportunity
In the current U.S. voluntary market, we see $2.00 to $7.00/metric ton depending on demand.
Utility executives are planning on $12.00 to $30.00/metric ton under proposed mandatory
markets; market will dictate price.
Typical
lagoon-based
635,000

from
the
farm
or
industry.
Substrate
(organic
materials)
We
pay
transport,
but
may
get

XERGI $3 MILLION INVESTMENT
AND NEW COOPERATION AGREEMENT
20
EPC has renegotiated its licensing arrangement with Danish Biogas Technology, A.S.
and its parent, Xergi. The new Cooperation Agreement better reflects the Company’s
build / own / operate business model and will provide substantial long-term savings in
reduced license fees to EPC and Microgy, Inc.
Pursuant
to
the
new
Cooperation
Agreement,
Xergi
acquired
$3
million
of
EPC’s
14%
convertible notes, having the same terms as the $5 million of our convertible notes
issued in March 2009, in payment of certain license fees.
We
believe
this
reflects
a
knowledgeable
party’s
commitment
to
EPC’s
business
model
and growth.


LONG-TERM PREMIUM PRICE AGREEMENTS WITH
MAJOR UTILITY SUPPORTS FUTURE PROJECTS
21
Our sales agreement with Xcel, like the comparable one with Pacific Gas & Electric,
highlights that our RNG
®
product is sold and priced as RENEWABLE ENERGY,
not
a
natural
gas substitute.
In
March
2009,
we
announced
a
long-term
RNG
®
supply
agreement
to
Xcel
Energy
(NYSE: XEL).  The ten-year contract, which is renewable for an additional ten years,
is
for
a
fixed
price
reflecting
the
value
of
our
green
RNG
®
versus
other
renewable
alternatives.
Xcel will use our RNG
®
product to generate carbon-neutral electricity.
The
agreement
will
help
Xcel
continue
to
meet
its
mandates
under
the
Colorado’s
Renewable Energy Standard and support the company’s efforts to reduce carbon dioxide
emissions.
The Colorado PUC has approved the agreement.

PROJECTS ARE PROFITABLE AND SCALABLE

Project portfolio build-out plan
Our
business
model
is
to
develop,
build
and
own
RNG
®
and
biogas
facilities
designed to be individually profitable and scalable in number, with the profitability of
any one facility not dependent upon the number of facilities.
We are encouraged by the drop in prices for metals and other commodities, which is
expected to lower construction costs on pending and planned projects.
Our rate of growth is dependent upon how quickly we can raise capital to construct
our existing shovel-ready projects and further develop our pipeline of projects which
we are ready to pursue.
Our
debt
service
requirements,
as
well
as
our
resources
for
debt
service
are
expected to scale in proportion to the number of projects we pursue.
Therefore, Ziegler bond funds are focused on the next two Texas projects and Swift;
projects
for
which
bond
financing
is
in
place
and
accessible
and
construction
is
underway.
Marathon’s process will determine what funds are initially available to complement
Ziegler’s efforts.


CALIFORNIA BOND TEST
25
What will be evaluated by bondholders on June 30, 2009:
Results of 60-day financial and operating performance test at Huckabay; and
Ability to raise new equity in the amount of $39 million ($45 million if Bar 20 had
been financed).
Discussion
The June 30
date is a point in time for bondholders to evaluate our performance
against the criteria established in September 2008.  The bondholders can then
determine their course of action. 
We
intend
to
discuss
our
performance
against
these
criteria
with
the
bondholders
and
what,
if any, accommodations we may require.
The tax-exempt bondholders are aware of the various initiatives to meet the
criteria and ultimately may be satisfied with progress toward meeting the
milestones.  However, should they decide to call the bonds, we would focus the
funds raised through Ziegler on the next two projects in the Texas portfolio and
Swift, which are unencumbered by the test, and build out those projects. 
We would then seek alternative financing for the California projects as the various
contracts remain in place and only spend a limited amount of funds until greater
certainty develops as to their financing. 
th


GOING-CONCERN QUALIFICATION
26
As is typical for start-up growth companies, going-concern qualifications are an
accounting disclosure requirement that results from the need to raise additional funding. 
The
amount
of
our
funding
requirements
is
based
on
our
projected
build-out
plans,
as
well as our ongoing General and Administration (G&A) requirements. Sources of capital
are expected to come from various initiatives discussed previously.  Funds raised are to
be
focused
on
Texas,
California,
or
Swift
projects
projects
that
have
initiated
construction
or
are
shovel
ready.
We have implemented significant steps to reduce our G&A expenses, but will need to
raise funds during the first half of 2009 in order to cover ongoing G&A, as well as interest
and dividend requirements.
We are actively seeking additional sources of capital to meet these financing needs and
requirements of our projects in development
