Item 4   Summary of Material Change
         --------------------------

VANCOUVER, CANADA, May 24, 2007 - Dynamotive Energy Systems
Corporation ("Dynamotive") (OTCBB: DYMTF), a leader in biomass-
to-biofuel technology, today reported its first quarter 2007
results.  For the three months ended March 31, 2007, the company
reported a loss of $3.2 million or $0.02 per share, compared with
a loss of $3.3 million or $0.03 a share for the same period a
year earlier. When stock-based compensation is excluded,
Dynamotive's Q1 2007 net loss was $2.4 million, compared with
$2.0 million during 2006. The slightly lower loss for the quarter
is due mainly to the lower stock based compensation, largely
offset by increased activity in most business areas. (All figures
are in US dollars.)  As at March 31, 2007, the company had cash
and cash equivalents of $4.4 million, compared to $11.7 million
at March 31, 2006. The lower cash level is mainly due to capital
expenditures for building the new, modular intermediate BioOil(R)
production plant at Guelph, Ontario, and upgrading the
established West Lorne, Ontario, facility.

5.1  Full Description of Material Change

VANCOUVER, CANADA, May 24, 2007 - Dynamotive Energy Systems
Corporation ("Dynamotive") (OTCBB: DYMTF), a leader in biomass-
to-biofuel technology, today reported its first quarter 2007
results.

For the three months ended March 31, 2007, the company reported a
loss of $3.2 million or $0.02 per share, compared with a loss of
$3.3 million or $0.03 a share for the same period a year earlier.
When stock-based compensation is excluded, Dynamotive's Q1 2007
net loss was $2.4 million, compared with $2.0 million during
2006. The slightly lower loss for the quarter is due mainly to
the lower stock based compensation, largely offset by increased
activity in most business areas. (All figures are in US dollars.)

As at March 31, 2007, the company had cash and cash equivalents
of $4.4 million, compared to $11.7 million at March 31, 2006. The
lower cash level is mainly due to capital expenditures for
building the new, modular intermediate BioOil(R) production plant at
Guelph, Ontario, and upgrading the established West Lorne,
Ontario, facility.

Commenting on the company's activities during the quarter
President and CEO Andrew Kingston said: "We continued our steady
progress in the first quarter of 2007 with the commissioning of
our Guelph plant under way and work on West Lorne accelerating.
We have now completed our initial production run of intermediate-
grade biofuel - BioOil Plus - at Guelph and we expect to have
both plants operational in the third quarter; signalling full
commercial operation.  Furthermore, our activities in Europe, the
U.S., Latin America and China continued at an increased pace,
with commercial project prospects in each of these markets.

"Strategically, we continue to have constructive discussions with
Mitsubishi, and we are consolidating our partnerships with
Consensus Business Group, Evolution Biofuels and Tecna.
Internally, we continue to grow our capabilities in every area of
the Dynamotive organization, and our progress can be easily
monitored through our website, which we update regularly,"
continued Kingston.

Outlook

"During the balance of 2007, we expect to achieve key milestones
with our existing project opportunities and add to them.  Having
two plants in operation later this year will give us a strong
competitive advantage in the marketplace, demonstrating the
production of cellulose-based fuels at commercial levels well
ahead of our competitors. We have noted, too, that there has been
specific growing interest in fast pyrolysis in the marketplace,
as well as an increasing recognition that this technology can co-
exist and support ethanol and biodiesel operations," concluded
Kingston.

Recent Highlights for 2007.

- -Hot commissioning commenced at new Guelph plant, followed by
completion of first intermediate-grade BioOil(R) production run May 23.

- -Major equipment delivered to West Lorne site as upgrading of
plant begins

- -Dynamotive announces project for up to six biofuel plants in
Argentina, subject to financing

- -First Resources Corporation developing partnerships with First
Nations People in Canada

- -Dynamotive contracts with Ontario Power Authority for green
electricity supply from West Lorne
