   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;Operating segments are components of an enterprise for which separate discrete financial
   information is available for evaluation by the chief operating decision-maker in making decisions
   on how to allocate resources and assess performance. The Company&amp;#8217;s chief operating decision-maker
   is its Chief Executive Officer. ATG views its operations and manages its business as one segment
   with three product offerings: software licenses, recurring services, and professional and education
   services. ATG evaluates these product offerings based on their respective revenues and gross
   margins. As a result, the financial information disclosed in the consolidated financial statements
   represents the material financial information related to our principal operating segment.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;Revenues from foreign sources were approximately $13.4&amp;#160;million and $14.7&amp;#160;million for the three
   months ended June&amp;#160;30, 2010 and 2009, respectively and $25.1&amp;#160;million and $25.4&amp;#160;million for the six
   months ended June&amp;#160;30, 2010 and 2009 respectively. Revenues from foreign sources were primarily
   generated from customers located in Europe and the Asia/Pacific region. All of the Company&amp;#8217;s
   product sales for the three and six months ended June&amp;#160;30, 2010 and 2009 were delivered from ATG&amp;#8217;s
   headquarters located in the United States.
   &lt;/div&gt;
