    &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;In June&amp;#160;2006, our shareholders approved the Hudson City Bancorp, Inc. 2006 Stock Incentive
    Plan (the &amp;#8220;SIP Plan&amp;#8221;) authorizing us to grant up to 30,000,000 shares of common stock. In July
    2006, the Compensation Committee of the Board of Directors of Hudson City Bancorp (the
    &amp;#8220;Committee&amp;#8221;), authorized grants to each non-employee director, executive officers and other
    employees to purchase shares of the Company&amp;#8217;s common stock, pursuant to the SIP Plan. Grants of
    stock options made through December&amp;#160;31, 2010 pursuant to the SIP Plan amounted to 23,120,000
    options at an exercise price equal to the fair value of our common stock on the grant date, based
    on quoted market prices. Of these options, 6,067,500 have vesting periods ranging from one to five
    years and an expiration period of ten years. The remaining 17,052,500 shares have vesting periods
    ranging from two to three years if certain financial performance measures are met. Subject to
    review and verification by the Committee, we believe we attained these performance measures and
    have therefore recorded compensation expense for these grants.
    &lt;/div&gt;
    &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;Compensation expense related to our outstanding stock options amounted to $2.2&amp;#160;million and $2.6
    million for the three months ended March&amp;#160;31, 2011 and 2010, respectively.
    &lt;/div&gt;
    &lt;div align="left" style="font-size: 10pt; margin-top: 12pt"&gt;&lt;i&gt;Stock Awards&lt;/i&gt;
    &lt;/div&gt;
    &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;During 2009, the Committee granted performance-based stock awards (the &amp;#8220;2009 stock awards&amp;#8221;)
    pursuant to the SIP Plan for 847,750 shares of our common stock. These shares were issued from
    treasury stock and will vest in annual installments over a three-year period if certain performance
    measures are met and employment continues through the vesting date. None of these shares may be
    sold or transferred before their January&amp;#160;2012 vesting date. We have determined that it is probable
    these performance measures will be met and have therefore recorded compensation expense for the
    2009 stock awards. Expense for the 2009 stock awards is recognized over the vesting period and is
    based on the fair value of the shares on the grant date which was $12.03. In addition to the 2009
    stock awards, grants were made in 2010 (the &amp;#8220;2010 stock awards&amp;#8221;) pursuant to the SIP Plan for
    18,000 shares of our common stock. Expense for the 2010 stock awards is recognized over the
    vesting period of three years and is based on the fair value of the shares on the grant date which
    was $13.12. Total compensation expense for stock awards amounted to $870,000 and $1.2&amp;#160;million for
    the three months ended March&amp;#160;31, 2011 and 2010, respectively.
