(“GGE”) entered into a long-term service agreement (the “LTSA”) with respect to GGE’s 58.8 MW fuel cell power platform in Hwaseong-si, Korea (the “GGE Platform”). The GGE Platform is comprised of 21 SureSource 3000 molten carbonate fuel cells (each a “Plant”). Each Plant is comprised of two 1.4-MW carbonate fuel cell modules. Pursuant to the LTSA, GGE and the Company have agreed that (i) GGE will purchase from the Company 42 1.4-MW carbonate fuel cell modules to replace existing fuel cell modules at the GGE Platform, (ii) the Company will provide certain balance of plant replacement components if and to the extent the parties reasonably determine existing components should be replaced, and (iii) the Company will provide long term operations and maintenance services for the GGE Platform.

The term of the LTSA with respect to each Plant will continue for seven years from the date of commissioning of the replacement fuel cell modules for such Plant.
