   &lt;div align="left" style="font-size: 10pt; margin-top: 12pt"&gt;&lt;b&gt;4. Line of Credit:&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;On December&amp;#160;20, 2010, the Company entered into a credit agreement with Bank of America, N.A.,
   as administrative agent, and a syndicate of lenders named therein (the &amp;#8220;Credit Agreement&amp;#8221;). Under
   the terms of the Credit Agreement, the credit facility includes an aggregate principal amount
   available of $407.5&amp;#160;million which
   consists of a $50&amp;#160;million fixed rate loan that matures on May&amp;#160;4, 2012, which was transferred
   from the Company&amp;#8217;s then existing credit agreement, and a $357.5&amp;#160;million revolving credit facility
   that matures on December&amp;#160;20, 2014. The revolving credit facility will be automatically increased
   by $50&amp;#160;million upon the maturity and repayment of the fixed rate loan. The fixed rate loan bears
   interest at a rate of 6.8% per annum, payable monthly in arrears. The revolving loans accrue
   interest, at the option of the Company, at either the base rate plus 1.75% per annum or the
   Eurodollar rate (as defined in the Credit Agreement) for the applicable term plus 2.75% per annum.
   The base rate is the highest of (a)&amp;#160;the Federal Funds Rate plus 0.50%, (b)&amp;#160;Bank of America&amp;#8217;s prime
   rate, and (c)&amp;#160;the Eurodollar rate plus 1.00%. Interest is payable on base rate loans quarterly in
   arrears and on Eurodollar loans in arrears on the last day of each interest period or, if such
   interest period exceeds three months, every three months. The Company&amp;#8217;s revolving credit facility
   includes a $20&amp;#160;million swingline loan sublimit and a $20&amp;#160;million letter of credit sublimit. It
   also contains an accordion loan feature that allows the Company to request an increase of up to
   $142.5&amp;#160;million in the amount available for borrowing under the revolving credit facility, whether
   from existing or new lenders, subject to terms of the Credit Agreement. No existing lender is
   obligated to increase its commitment. The Credit Agreement is secured by a first priority lien on
   substantially all of the Company&amp;#8217;s assets. The Credit Agreement contains restrictive covenants and
   events of default including the following:
   &lt;/div&gt;

   facility as of March&amp;#160;31, 2011 and December&amp;#160;31, 2010, respectively, of which $50&amp;#160;million represented
