     5.1 Full Description of Material Change

VANCOUVER, BC, Canada, August 1, 2007 - Dynamotive Energy Systems
Corporation ("Dynamotive") (OTCBB: DYMTF), and Mitsubishi Corporation
("Mitsubishi"), Japan's largest general trading and investment company
(sogo shosha) with over 200 bases of operations in approximately 80
countries worldwide, signed a letter of agreement ("LOA") whereby
development and strategic opportunities for cooperation are identified
and protocols are established to jointly advance them.

The comprehensive LOA between Mitsubishi's New Energy Business Unit,
Business Innovation Group, and Dynamotive lays out the framework for
exploring areas of cooperation in project development, finance,
technology development, product research and application, and fuel
supply and trading. It also recognizes Dynamotive's market potential in
the field of cellulose based fuels providing it and its partners a
unique opportunity for growth.

The Companies have worked cooperatively for the past 18 months, having
previously signed a Memorandum of Understanding with Mitsubishi Canada
Ltd. ("Mitsubishi Canada", see announcement Dec. 20, 2005), and have
identified projects and commercial opportunities that are earmarked for
early development. Each opportunity described in the LOA is subject to
negotiation of a definitive agreement between Dynamotive and the
corresponding business unit of Mitsubishi.

Included in the project opportunities are the current development in
Argentina (see announcement May 10, 2007) and other projects in Latin
America, project development in China where Dynamotive has worked in
cooperation with the National Development and Reform Commission (see
announcement Dec. 12, 2006), project opportunities in the US where
Dynamotive has an operating subsidiary and new project opportunities in
Japan and South East Asia, among others that are introduced by
Mitsubishi.

In addition, the LOA envisages project finance and supply of equipment
by Mitsubishi in line with the previous MOU signed between Dynamotive
and Mitsubishi Canada.  Specifically, the Companies have agreed to
initiate preliminary discussion for the refinancing of Dynamotive's
current plant and equity participation in West Lorne. This plant has an
asset value of approximately U.S. $18 million, with the full output of
West Lorne contractually committed.

Fuel supply and trading:  the LOA framework establishes parameters for
the possibility to supply BioOil(R ) from Evolution Biofuels (Guelph
Plant) to Mitsubishi for testing and market development purposes as part
of an overall expansion strategy. Plant production is rated at 50,000
tonnes annually.

Technology licensing: Mitsubishi has requested the licensing of
Dynamotive's technology for small plant capacity (20 tonnes and under)
for fabrication and marketing in Japan.  Dynamotive is evaluating, as a
result of this request, the opportunity to deliver a 15 tonne per day
plant to Mitsubishi. Dynamotive currently has a plant of this capacity
that could be refurbished for this purpose.

About Dynamotive

Dynamotive Energy Systems Corporation is an energy solutions provider
headquartered in Vancouver, Canada, with offices in the USA, UK and
Argentina. Its carbon/greenhouse-gas-neutral fast pyrolysis technology uses
medium temperatures and oxygen-free conditions to turn dry, waste cellulosic
biomass into BioOil for power and heat generation. BioOil can be further
converted into vehicle fuels and chemicals.  The final stages of the
commissioning process at the Guelph plant and the reconstruction of the West
Lorne plant may be seen by viewing photographs regularly posted on the
company's website at www.dynamotive.com


About BioOil(R)

BioOil is an industrial fuel produced from cellulose waste material. When
combusted it produces substantially less smog-precursor nitrogen oxides
('NOx') emissions than conventional oil as well as little or no sulfur oxide
gases ('SOx'), which are a prime cause of acid rain.  BioOil and BioOil
Plus(tm) are price-competitive replacements for heating oils #2 and #6 that are
widely used in industrial boilers and furnaces. They have been EcoLogo
certified, having met stringent environmental criteria for industrial fuels
as measured by Environment Canada's Environmental Choice Program. BioOil can
be produced from a variety of residue cellulosic biomass resources and is
not dependent on food-crop production.
