STYLE="margin-top:6px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2"><U>Site Work Agreement between Red River Environmental Products, LLC and BE&amp;K Construction Company, LLC </U></FONT></P> <P
STYLE="margin-top:12px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2">On January&nbsp;27, 2009, through our indirect subsidiary Red River Environmental Products, LLC (&#147;Red River&#148;), we concluded a Site Work Agreement with BE&amp;K
Construction Company, LLC (&#147;BE&amp;K&#148;) in connection with the activated carbon manufacturing facility we are building in Red River Parish, Louisiana (the &#147;Project&#148;). As previously disclosed (in our Form 10-K dated March&nbsp;14,
2008, Form 8-K dated September&nbsp;12, 2008 and Form 10-Q dated November&nbsp;7, 2008), Red River has entered into two other related agreements with BE&amp;K: (1)&nbsp;an Engineering, Procurement and Construction Agreement, dated as of
January&nbsp;29, 2008, as supplemented by two Letter Agreements entered into in conjunction therewith, which provided for certain preliminary design, engineering and site work for the Project (the &#147;Preliminary EPC Agreement&#148;); and
(2)&nbsp;an Amended and Restated Engineering, Procurement and Construction Agreement, dated as of September&nbsp;8, 2008, which provided for certain engineering, design, procurement, construction, construction management, testing, commissioning and
related services for the Project (the &#147;Amended EPC Agreement&#148;). The Site Work Agreement further amends, and with the Amended EPC Agreement, fully replaces the Preliminary EPC Agreement. Pursuant to the Site Work Agreement, BE&amp;K will
perform services to ensure that stormwater controls are in place, Project site access, laydown and other areas for construction, multi-hearth furnace (&#147;MHF&#148;) foundations and the Project site and MHF foundations for MHF erection and
construction of the balance of the Project are prepared for construction, which construction is to be performed by BE&amp;K pursuant to the terms, and subject to the conditions of, the Amended EPC Agreement (the &#147;Site Work&#148;). Under the
Site Work Agreement, Red River will reimburse BE&amp;K for subcontracts let to effect the &#147;Site Work&#148; (the &#147;Contractor Subcontracts&#148;). BE&amp;K is obligated to provide to Red River for its approval any proposed change under any
of the Contractor Subcontracts which change(s), in the aggregate, may cause the aggregate amount for which Red River shall reimburse BE&amp;K for costs BE&amp;K incurs under the Contractor Subcontracts to exceed the Red River&#146;s target cost of
Nine Million Six Hundred Thirty-six Thousand Four Hundred Twenty-three dollars ($9,636,423). The Site Work performed by BE&amp;K shall be in accordance with the Amended EPC Agreement&#146;s Project Schedule, and upon completion and payment, the Site
Work shall become &#147;Work,&#148; as defined under the Amended EPC Agreement, and thus subject to the performance test, warranty and all other requirements and obligations of BE&amp;K under the Amended EPC Agreement. All amounts paid to BE&amp;K
under the Site Work Agreement will be counted as part of the &#147;Total Work Cost,&#148; as such term is defined under the Amended EPC Agreement. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2">We will
file the Site Work Agreement as an Exhibit to our Form 10-K for the fiscal year ended December&nbsp;31, 2008. </FONT></P>
