OTHER EVENTS

Notice of Default from JBS Swift

On March 31, 2010, Microgy Grand Island, LLC (“MGH”), a subsidiary of Environmental Power Corporation (the “Company”), received notice from JBS Swift & Co. (“Swift”) that Swift considers MGH to be in default under the terms of that certain Biogas Agreement, dated as of September 1, 2006, between Swift and MGH, as amended to date (as so amended, the “Biogas Agreement”) and the Lease Agreement, dated September 1, 2006, between Swift and MGH (the “Lease Agreement”). The Biogas Agreement and the Lease Agreement relate to MGH’s biogas facility located at Swift’s Grand Island, Nebraska beef processing plant. In the notice, Swift cited MGH’s failure to make biogas deliveries and to make liquidated damages payments pursuant to the Biogas Agreement, as well as MGH’s failure to provide adequate assurances that its financial condition will permit it to complete the biogas facility as defaults under the Biogas Agreement. A default under the Biogas Agreement is a default under the Lease Agreement. Swift stated in its notice that if these defaults are not cured within the 60-day cure period provided for in the Biogas Agreement, it reserves the right to terminate the Biogas Agreement and the Lease and to exercise its rights under the agreements and the law.

MGH believes that it has defenses to these claims of default and expects to contest such claims if necessary, and also expects to meet with Swift to attempt to resolve them.
