      &lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;On

      March 6, 2013 the Company completed its acquisition of

      of $1,214,330.&amp;#160;&amp;#160;Sabio provides air quality

      monitoring products including ambient air instrumentation and

      continuous emission monitoring systems.&amp;#160;&amp;#160;The

      acquisition of Sabio was accounted for using the acquisition

      method of accounting and, accordingly, assets acquired,

      liabilities assumed and consideration paid were recorded at

      their estimated fair values as of the acquisition

      date.&lt;/font&gt;
