Side Letter



to the Addendum to Licence Agreement of 12 May 2000



Microgy Cogeneration Systems, Inc. (Microgy) and Danish Biogas Technology A/S (DBT) have on 14 day of April 2003 entered into an Addendum to the
Licence Agreement of 12 May 2000 between the said parties.



The purpose of this
side letter is to Illustrate Microgy and DBTs mutual understanding of the limitation of liability clause (sections 6.1. and 6.2) by the examples listed below. The examples are only included for Illustrative purposes and shall in no
circumstance be viewed as an exhaustive reproduction of the limitation of liability clauses (sections 6.1 and 6.2):



|1. | In the event that DBT delivers defective construction drawings or renders defective consultancy advice, e.g., valves pointing in the wrong direction, then DSTs liability for
such defect is subject to the limitation of liability in section 6.1, regardless of the time of ascertaining such defects or the costs Involved in remedying such defects. Thus section 6.2 does not apply to the defect.
|-- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|2. | In the event that DBT does not deliver the requested construction drawings or does not have 1-2 engineers at the construction site as provided for in the Addendum, and DBT continues
not to deliver the construction drawings or not to have 1-2 engineers at the construction site and does not acknowledge this breach and commences to cure this breach within 30 days after Microgy has given DBT 30 days notice and subsequently
continues not to cure this breach with reasonable diligence until this breach has been cured, then DBTs liability for this breach of the provisions in the Addendum Is not subject to the limitations of liability in section 6.1, cf. section 6.
|-- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|3. | In the event that DBT delivers defective process and Instrument diagrammes and process control system descriptions, then DBTs liability for defects is subject to the
limitations of liability In section 6.1 regardless of the time of ascertaining such defect or the costs Involved in remedying such defects. Thus, section 6.2 does not apply.
|-- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|4. | In the event that DBT does not deliver the requested process and instrument diagrammes and the process control system descriptions as provided for in the Addendum, and DBT continues
not to deliver the process and instrument diagrammes and the process control system descriptlons, and DBT does not acknowledge this breach and commences to cure this breach within 30 days after Microgy has given DBT 30 days notice and
subsequently continues not to cure this breach with reason able diligence until this breach has been cured by delivering the process and instrument diagrammes and the process control system descriptions after Microgy has given DBT 30 days
notice, then DBTs liability for breach of the provisions in the Addendum is not subject to the limitation of liability in section 6.1, cf, section 6.2.
|-- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



Regardless of the fact that the above-mentioned examples do not concern DSTs obligation provided for in section 3.1.1. and section
3.1.5, these sections shall be construed as provided for above.
