       In June 2007, the Company issued and sold $165.0&amp;#160;million
       aggregate principal amount of 3.25%&amp;#160;Convertible Senior
       Notes due 2027 (the &amp;#8220;Notes&amp;#8221;) in a public offering. The
       Notes bear interest at a rate of 3.25% per year on the principal
       amount, accruing from June&amp;#160;20, 2007. Interest is payable
       semi-annually on January 1 and July&amp;#160;1. The Company made
       interest payments of $2.7&amp;#160;million on each of June&amp;#160;30,
       2009, December&amp;#160;31, 2009 and July&amp;#160;1, 2010. The Notes
       will mature on July&amp;#160;1, 2027, subject to earlier conversion,
       redemption or repurchase.
   &lt;/div&gt;
   &lt;div style="margin-top: 4pt; 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 liability and equity components of the Notes are separately
       accounted for in a manner that reflects the Company&amp;#8217;s
       nonconvertible debt borrowing rate because their terms include
       partial cash settlement. The Company amortizes the resulting
       debt discount over the period the convertible debt is expected
       to be outstanding as additional non-cash interest expense. The
       Company has determined that its nonconvertible borrowing rate at
       the time the Notes were issued was 6.9%. Accordingly, the
       Company estimated the fair value of the liability (debt)
       component as $144.1&amp;#160;million upon issuance of the Notes. The
       Company allocated the excess of the proceeds received over the
       estimated fair value of the liability component totaling
       $20.9&amp;#160;million to the conversion (equity) component. The
       carrying amount of the equity component of the Notes was
       $8.2&amp;#160;million and $4.1&amp;#160;million at December&amp;#160;31,
       2009 and September&amp;#160;30, 2010, respectively, and is recorded
       as a debt discount and is netted against the remaining principal
       amount outstanding on the Company&amp;#8217;s unaudited consolidated
       balance sheets.
   &lt;/div&gt;
   &lt;div style="margin-top: 4pt; 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;
       In connection with obtaining the Notes, the Company incurred
       $4.5&amp;#160;million in debt issuance costs, of which
       $4.0&amp;#160;million was allocated to the liability component and
       $0.5&amp;#160;million was allocated to the equity component. The
       carrying amount of the liability component of the debt issuance
       costs was $0.6&amp;#160;million and $0.1&amp;#160;million at
       December&amp;#160;31, 2009 and September&amp;#160;30, 2010,
       respectively, and is recorded as a debt discount and is netted
       against the remaining principal amount outstanding on the
       Company&amp;#8217;s unaudited consolidated balance sheets.
   &lt;/div&gt;
   &lt;div style="margin-top: 4pt; font-size: 1pt"&gt;&amp;#160;

       The debt discount, which includes the equity component and the
       liability component of the debt issuance costs, is being
       amortized as interest expense using the effective interest
       method through July&amp;#160;1, 2011, the first redemption date of
       the Notes. The Company recorded total interest expense of
       approximately $2.9&amp;#160;million for each of the three months
       ended September&amp;#160;30, 2009 and 2010, which consisted of
       $1.3&amp;#160;million in interest expense at a rate of 3.25% per
       year and $1.6&amp;#160;million in amortization of the debt discount.
       The Company recorded total interest expense of approximately
       $8.8&amp;#160;million and $8.7&amp;#160;million for the nine months
       ended September&amp;#160;30, 2009 and 2010, respectively, which
       consisted of $4.0&amp;#160;million in interest expense at a rate of
       3.25% per year and $4.8&amp;#160;million and $4.7&amp;#160;million in
       amortization of the debt discount for the nine months ended
       September&amp;#160;30, 2009 and 2010, respectively.
   &lt;/div&gt;
   &lt;div style="margin-top: 4pt; font-size: 1pt"&gt;&amp;#160;

   &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 principal amount of the liability component of the Notes was
       $165.0&amp;#160;million at each of December&amp;#160;31, 2009 and
       September&amp;#160;30, 2010. The unamortized debt discount was
       $8.8&amp;#160;million and $4.2&amp;#160;million at December&amp;#160;31,
       2009 and September&amp;#160;30, 2010, respectively. The net carrying
       amount of the liability component of the Notes was
       $156.2&amp;#160;million and $160.8&amp;#160;million at December&amp;#160;31,
       2009 and September&amp;#160;30, 2010, respectively. As the first
       redemption date of the Notes is July&amp;#160;1, 2011, the Company
       reclassified the net carrying amount of the liability component
       to current liabilities in the unaudited consolidated balance
       sheet as of September&amp;#160;30, 2010.
   &lt;/div&gt;

       The Company has evaluated whether certain features of the Notes
       cause the Notes to be considered to be indexed to the
       Company&amp;#8217;s own stock using a two-step approach to evaluate
       the Notes&amp;#8217; contingent exercise and
   settlement provisions. The Company has determined that the
       Notes&amp;#8217; embedded conversion options are indexed to the
       Company&amp;#8217;s own stock and, therefore, do not require
       bifurcation and separate accounting.
   &lt;/div&gt;

       On August&amp;#160;4, 2010, the Company entered into a five-year
       $175.0&amp;#160;million senior secured revolving credit facility
       agreement with a syndicate of banks led by JPMorgan Chase Bank,
       N.A. as administrative agent, which is available until
       August&amp;#160;4, 2015 (the &amp;#8220;Credit Agreement&amp;#8221;).
       Borrowings under the Credit Agreement are available for general
       corporate purposes which may include outstanding debt repayments
       and acquisitions. Loans under the Credit Agreement bear interest
       at a rate per annum equal to, at the election of the Company,
       (i)&amp;#160;the Adjusted LIBO Rate (as defined in the Credit
       Agreement) plus a margin which will vary between 2.25% and 3.00%
       based on the Company&amp;#8217;s Leverage Ratio (as defined in the
       Credit Agreement) or (ii)&amp;#160;an Alternate Base Rate (as
       defined in the Credit Agreement) plus a margin which will vary
       between 1.25% and 2.00% based on the Company&amp;#8217;s Leverage
       Ratio. Overdue amounts under the Credit Agreement bear interest
       at a rate per annum equal to 2% plus the rate otherwise
       applicable to such loan.
   &lt;/div&gt;
   &lt;div style="margin-top: 4pt; 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 is required to pay a commitment fee at a rate per
       annum which will vary between 0.30% and 0.50% based on the
       Company&amp;#8217;s Leverage Ratio on the average daily unused amount
       of the credit facility commitments during the period for which
       payment is made, payable quarterly in arrears. The Company
       records this fee in interest expense. The Company may optionally
       prepay loans or reduce the credit facility commitments at any
       time, without penalty.
   &lt;/div&gt;
   &lt;div style="margin-top: 4pt; 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;
       In connection with obtaining the senior secured credit facility,
       the Company incurred $1.7&amp;#160;million in debt issuance costs in
       August 2010, which is amortized as interest expense over the
       term of the senior secured credit facility using the effective
       interest method. The Company recorded total interest expense of
       approximately $0.1&amp;#160;million, for the three and nine months
       ended September&amp;#160;30, 2010.
   &lt;/div&gt;
   &lt;div style="margin-top: 4pt; 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;
       Under the terms of the Credit Agreement and related loan
       documents, the loans and other obligations of the Company are
       guaranteed by the material domestic subsidiaries of the Company,
       and are secured by substantially all of the tangible and
       intangible assets of the Company and each material domestic
       subsidiary guarantor (including, without limitation,
       intellectual property and the capital stock of certain
       subsidiaries). In addition, the Credit Agreement contains
       customary affirmative and negative covenants applicable to the
       Company and its subsidiaries with respect to its operations and
       financial conditions, including a leverage ratio, a senior
       leverage ratio, an interest coverage ratio and a minimum
       liquidity covenant. The Company continues to be in full
       compliance with all covenants contained in the Credit Agreement.
   &lt;/div&gt;
   &lt;div style="margin-top: 4pt; font-size: 1pt"&gt;&amp;#160;

       As of September&amp;#160;30, 2010 and November&amp;#160;5, 2010, no
       amounts were outstanding under the credit facility.
   &lt;/div&gt;
   &lt;/div&gt;
