   &lt;div align="left" style="font-size: 10pt; margin-top: 12pt"&gt;&lt;b&gt;Note 8 &amp;#8212; Borrowings&lt;/b&gt;
   &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;In February&amp;#160;2009, the Company entered into a credit agreement with Bank of America, which
   provided for a one-year senior secured revolving credit facility in an amount of up to $180.0
   million that is subject to a borrowing base formula. The revolving credit facility has a sub-limit
   for the issuance of letters of credit in a face amount of up to $10.0&amp;#160;million. Advances under the
   revolving credit facility were used to consummate the Company&amp;#8217;s acquisition of Tepnel and are also
   available for other general corporate purposes. At the Company&amp;#8217;s option, loans accrue interest at a
   per annum rate based on, either: the base rate (the base rate is defined as the greatest of (i)&amp;#160;the
   federal funds rate plus a margin equal to 0.50%, (ii)&amp;#160;Bank of America&amp;#8217;s prime rate and (iii)&amp;#160;the
   London Interbank Offered Rate (&amp;#8220;LIBOR&amp;#8221;) plus a margin equal to 1.00%); or LIBOR plus a margin equal
   to 0.60%, in each case for interest periods of 1, 2, 3 or 6&amp;#160;months as selected by the Company. In
   connection with the credit agreement, the Company also entered into a security agreement, pursuant
   to which the Company secured its obligations under the credit agreement with a first priority
   security interest in the securities, cash and other investment property held in specified accounts
   maintained by Merrill Lynch, Pierce, Fenner &amp;#038; Smith Incorporated, an affiliate of Bank of America.
   In connection with the execution of the credit agreement with Bank of America, the Company
   terminated the commitments under its unsecured bank line of credit with Wells Fargo Bank, N.A.,
   effective as of February&amp;#160;27, 2009. There were no amounts outstanding under the Wells Fargo Bank
   line of credit as of the termination date.
   &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;In March&amp;#160;2009, the Company borrowed $170.0&amp;#160;million under the revolving credit facility in
   anticipation of funding its acquisition of Tepnel. Also in March&amp;#160;2009, the Company and Bank of
   America amended the credit agreement to increase the amount that the Company can borrow from time
   to time under the credit agreement from $180.0&amp;#160;million to $250.0&amp;#160;million. In April&amp;#160;2009, the
   Company borrowed an additional $70.0&amp;#160;million under its revolving credit facility with Bank of
   America.
   &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;In February&amp;#160;2010, the Company entered into a second amendment to its credit agreement with
   Bank of America, pursuant to which, among other things, the maturity date of the Company&amp;#8217;s senior
   secured revolving credit facility was extended for an additional one-year period. As extended, the
   credit facility now expires on February&amp;#160;25, 2011. As of September&amp;#160;30, 2010, the total principal
   amount outstanding under the revolving credit facility was $240.0&amp;#160;million and the interest rate
   payable on such outstanding amount was approximately 0.86%.

   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;As a result of the Tepnel acquisition, the Company assumed Tepnel&amp;#8217;s pre-existing fixed-rate
   term loan, which accrues interest at an effective rate of 6.6% and is to be repaid in quarterly
   installments through February&amp;#160;2018. As of September&amp;#160;30, 2010, the outstanding principal amount
   under this loan was &amp;#163;0.5&amp;#160;million, or $0.8&amp;#160;million based on the exchange rate of &amp;#163;1 to $1.58 as of
   the balance sheet date. Of this outstanding amount, $0.2&amp;#160;million and $0.6&amp;#160;million was classified as
   short-term and long-term, respectively, as of September&amp;#160;30, 2010.
