       During the three months ended March&amp;#160;31, 2011, the Company
       acquired the outstanding equity of txttools Limited
       (&amp;#8220;txttools&amp;#8221;) pursuant to the Share Purchase Agreement,
       for &amp;#163;3.85&amp;#160;million in cash, or approximately
       $6.1&amp;#160;million at the time of closing, net of cash acquired.
       Transaction costs of approximately $0.1&amp;#160;million are
       reflected in general and administrative expenses in the
       consolidated statements of operations.
   &lt;/div&gt;
   &lt;div style="margin-top: 6pt; font-size: 1pt"&gt;&amp;#160;
   &lt;/div&gt;
   &lt;div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"&gt;
       txttools is a provider of mass notification solutions in the
       United Kingdom and Ireland for educational and government
       organizations that allow clients to record, schedule, send and
       track voice, email, text and short message service (SMS)
       communications to their constituents. The Company believes the
       acquisition of txttools supports the Company&amp;#8217;s long-term
       strategic direction and the demands for innovative technology in
       the education industry. Management believes that the acquisition
       of txttools will help the Company meet the growing demands of
       its clients in the United Kingdom and Ireland, including the
       ability to send mass communications and notifications via
       various means.
   &lt;/div&gt;
   &lt;div style="margin-top: 6pt; font-size: 1pt"&gt;&amp;#160;
   &lt;/div&gt;
   &lt;div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"&gt;
       The Company has accounted for the merger under the acquisition
       method of accounting. Of the total estimated purchase price of
       $6.2&amp;#160;million, a preliminary estimate of $1.3&amp;#160;million
       was allocated to net tangible liabilities assumed, and
       $5.1&amp;#160;million was allocated to definite-lived intangible
       assets acquired. Definite-lived intangible assets of
       $5.1&amp;#160;million consist of the value assigned to
       txttools&amp;#8217; customer relationships of $4.5&amp;#160;million and
       developed and core technology of $0.6&amp;#160;million. The Company
       will amortize the value of txttools&amp;#8217; customer relationships
       over seven years and the developed and core technology over
       three years. Approximately $2.4&amp;#160;million has been allocated
       to goodwill and is not deductible for tax purposes. Goodwill
       represents factors including expected synergies from combining
       operations. The results of operations of txttools during the
       three months ended March&amp;#160;31, 2011 were not material to the
       Company&amp;#8217;s consolidated financial statements.
   &lt;/div&gt;
   &lt;div style="margin-top: 12pt; font-size: 1pt"&gt;&amp;#160;
   &lt;/div&gt;
   &lt;div align="left" style="margin-left: 2%; margin-right: 0%; font-size: 10pt; font-family: Arial, Helvetica; color: #000000; background: transparent"&gt;
       &lt;b&gt;&lt;i&gt;&lt;font style="font-family: 'Times New Roman', Times"&gt;Saf-T-Net,
       Inc. Merger&lt;/font&gt;&lt;/i&gt;&lt;/b&gt;
   &lt;/div&gt;
   &lt;div style="margin-top: 6pt; font-size: 1pt"&gt;&amp;#160;
   &lt;/div&gt;
   &lt;div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"&gt;
       On March&amp;#160;19, 2010, the Company completed its merger with
       Saf-T-Net, Inc. (&amp;#8220;Saf-T-Net&amp;#8221;) pursuant to the
       Agreement and Plan of Merger dated March&amp;#160;7, 2010. Pursuant
       to the Agreement and Plan of Merger, the Company paid merger
       consideration of $34.4&amp;#160;million. The effective cash portion
       of the purchase price of Saf-T-Net before transaction costs of
       approximately $0.5&amp;#160;million was $34.2&amp;#160;million, net of
       Saf-T-Net&amp;#8217;s March&amp;#160;19, 2010 cash balance of
       $0.2&amp;#160;million. The transaction costs are reflected in
       general and administrative expenses in the consolidated
       statements of operations.
   &lt;/div&gt;
   &lt;div style="margin-top: 6pt; font-size: 1pt"&gt;&amp;#160;
   &lt;/div&gt;
   &lt;div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"&gt;
       Saf-T-Net was the provider of AlertNow, a leading messaging and
       mass notification solution for the K-12 marketplace. The Company
       believes the merger with Saf-T-Net supports the Company&amp;#8217;s
       long-term strategic direction and the demands for innovative
       technology in the education industry. The Company believes that
       the merger with Saf-T-Net will help the Company meet the growing
       demands of its clients, including the ability to send mass
       communications via various means.
   &lt;/div&gt;

   &lt;/div&gt;
   &lt;div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"&gt;
       The Company accounted for the merger under the acquisition
       method of accounting. Of the total purchase price of
       $34.4&amp;#160;million, $6.9&amp;#160;million has been allocated to net
       tangible liabilities acquired, and $15.7&amp;#160;million has been
       allocated to definite-lived intangible assets acquired.
       Definite-lived intangible assets consist of the value assigned
       to
   Saf-T-Net&amp;#8217;s customer relationships of $12.7&amp;#160;million,
       developed and core technology of $2.3&amp;#160;million, and
       trademarks of $0.7&amp;#160;million. The Company amortizes the value
       of Saf-T-Net&amp;#8217;s customer relationships over seven years and
       the developed and core technology and trademarks, each over
       three years. Approximately $25.6&amp;#160;million has been allocated
       to goodwill and is not deductible for tax purposes. Goodwill
       represents factors including expected synergies from combining
       operations and is the excess of the purchase price of an
       acquired business over the fair value of the net tangible and
       intangible assets acquired. The Company included the financial
       results of Saf-T-Net in its consolidated financial statements
       beginning March&amp;#160;20, 2010.
