&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company entered into a licensing agreement
with a biomedical entity during the year ended December 31, 2005 and received an initial license fee of $50,000. This fee is deferred
and recognized on a straight-line basis over the life of the license agreement of 7 years. The Company recognized revenue of approximately
$1,250 for this agreement during each of the three months ended June 30, 2013 and 2012. The Company recognized revenue of approximately
$2,500 for this agreement during each of the six months ended June 30, 2013 and 2012.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;On October 30, 2012, the Company and MG Energy
LLC, a Delaware limited liability company (&amp;#147;MG Energy&amp;#148;) , a company in which a shareholder of the Company holds a position,
entered into a License and Supply Agreement (the &amp;#147;Agreement&amp;#148;), effective October 26, 2012, pursuant to which the Company
licensed certain intellectual property and improvements thereto to MG Energy, for use in the manufacture and sale of energy recovery
ventilators (&amp;#147;ERV&amp;#148;) and certain other HVAC systems for installation in commercial, residential or industrial buildings
in North America and South America in exchange for the cancellation of $2,034,521 of debt due to MG Energy. MG Energy also agreed
to purchase its requirements of certain ConsERV products from the Company for MG Energy&amp;#146;s use, pursuant to the terms and
conditions of the Agreement. MG Energy will also pay royalties, as defined, to the Company on the net sales of each product or
system sold. The term of the Agreement will expire upon the last to expire of the underlying patent rights for the licensed technology.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company has identified all of the deliverables
under the Agreement and has determined significant deliverables to be the license for the intellectual property and the supply
services. In determining the units of accounting, the Company evaluated whether the license has stand alone value to MG Energy
based upon consideration of the relevant facts and circumstances of the Agreement. The Company determined that the license does
not have stand alone value to the licensee and, therefore, should be combined with the supply agreement as one unit of accounting.
The initial payment for the license agreement will be treated as an advance payment and recognized over the performance period
of the supply agreement. Royalties will be recognized as revenue when earned. The Company recognized revenue of $29,920 in license
fees and $316,791 in product sales relating to this Agreement during the three months ended June 30, 2013. The Company recognized
revenue of $59,839 in license fees and $792,078 in product sales relating to this Agreement during the six months ended June 30,
2013.&lt;/p&gt;

Deferred revenue is a liability as of the balance sheet date related to a revenue producing activity for which revenue has not yet been recognized. Generally, an entity records deferred revenue when it receives consideration from a customer before achieving certain criteria that must be met for revenue to be recognized in conformity with GAAP.</ElementDefenition><ElementReferences>Reference 1: http://www.xbrl.org/2003/role/presentationRef
