  <p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">On
  June&nbsp;3, 2008, Aon Corporation and its subsidiaries and affiliates
  (collectively, the &#147;Company&#148;) entered into an Amendment No.&nbsp;6 (&#147;Amendment&#148;)
  to the Agreement among the Attorney General of the State of New York, the
  Superintendent of Insurance of the State of New York, the Attorney General of
  the State of Connecticut, the Illinois Attorney General, the Director of the
  Division of Insurance, Illinois Department of Financial and Professional Regulation
  (collectively, the &#147;State Agencies&#148;) dated March&nbsp;4, 2005 (the &#147;Settlement
  Agreement&#148;).&#160; The Amendment amends the
  Settlement Agreement to permit the Company, after acquiring a controlling
  interest in an insurance brokerage that accepts contingent compensation, to
  continue to accept contingent compensation from the acquired company&#146;s existing
  customers for three years from the effective date of acquisition, subject to
  certain restrictions.</font></p>
  
  <p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
  
  <p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The
  Amendment requires that if the Company accepts contingent compensation from the
  existing customers of an acquired company during this three-year phase-out
  period, the Company must, among other things, prohibit the acquired company
  from accepting contingent compensation with respect to business from its
  existing clients for which it was not receiving contingent compensation at the
  time of the acquisition or any new clients.&#160;
  The Amendment further requires the Company to subject an acquired
  company that receives contingent commissions to other business reforms agreed
  to in the Settlement Agreement within 180 days of the effective date of the
  acquisition or at the later renewal of each policy if compliance can not be
  completed with regard to a policy within the 180-day time frame.&#160; The Amendment provides that, after acquiring
  such an insurance brokerage, the Company must disclose on its website and in
  other public pronouncements that it accepts contingent compensation as to the
  acquired company and provide information regarding the acquired company and the
  applicable three-year transition period.</font></p>

  Item 1.01.              Entry
  into a Material Definitive Agreement.
  On
  June 3, 2008, Aon Corporation and its subsidiaries and affiliates
  (collectively, the "Company") entered into an Amendment No. 6 ("Amendment")
  to the Agreement among the Attorney General of the State of New York, the
  Superintendent of Insurance of the State of New York, the Attorney General of
  the State of Connecticut, the Illinois Attorney General, the Director of the
  Division of Insurance, Illinois Department of Financial and Professional Regulation
  (collectively, the "State Agencies") dated March 4, 2005 (the "Settlement
  Agreement").  The Amendment amends the
  Settlement Agreement to permit the Company, after acquiring a controlling
  interest in an insurance brokerage that accepts contingent compensation, to
  continue to accept contingent compensation from the acquired company's existing
  customers for three years from the effective date of acquisition, subject to
  certain restrictions.
  The
  Amendment requires that if the Company accepts contingent compensation from the
  existing customers of an acquired company during this three-year phase-out
  period, the Company must, among other things, prohibit the acquired company
  from accepting contingent compensation with respect to business from its
  existing clients for which it was not receiving contingent compensation at the
  time of the acquisition or any new clients. 
  The Amendment further requires the Company to subject an acquired
  company that receives contingent commissions to other business reforms agreed
  to in the Settlement Agreement within 180 days of the effective date of the
  acquisition or at the later renewal of each policy if compliance can not be
  completed with regard to a policy within the 180-day time frame.  The Amendment provides that, after acquiring
  such an insurance brokerage, the Company must disclose on its website and in
  other public pronouncements that it accepts contingent compensation as to the
  acquired company and provide information regarding the acquired company and the
  applicable three-year transition period.
  The
  foregoing summary is qualified in its entirety by reference to the Amendment, a
  copy of which is attached hereto as Exhibit 10.1 and is incorporated
  herein by reference.  Aon Corporation
  filed the Settlement Agreement as Exhibit 10.1 to its Form 8-K filed
  with the Securities and Exchange Commission on March 7, 2005.
