HRH Hilb Rogal & Hobbs

Hilb Rogal & Hobbs Company (NYSE:HRH), one of the world�s largest insurance and risk management intermediaries, today reiterated that the election deadline for HRH shareholders to make merger consideration elections in connection with the proposed merger with Willis Group Holdings Limited (NYSE:WSH) is 5 p.m., New York City time, on September 29, 2008. HRH shareholders of record wishing to make an election regarding the form of consideration they would prefer to receive must deliver to Mellon Investor Services LLC, the exchange agent in the merger, the following: properly completed election forms, together with stock certificates, if any, or a properly completed notice of guaranteed delivery. These must be received by Mellon by the election deadline of 5 p.m., New York City time, on September 29, 2008. HRH shareholders who hold their shares in �street name,� hold restricted share awards, or hold shares through the Employee Stock Purchase Plan or Retirement Savings Plan may have an election deadline earlier than September 29, 2008. They should carefully review any materials they received to determine the election deadline applicable to them. HRH shareholders are entitled to make an election about the type of merger consideration (cash or shares of Willis common stock) they prefer to receive for each share of HRH common stock exchanged in the merger. In each case, such consideration will have a value approximately equal to $46.00. Based on the $35.81 average price per share of Willis common stock on the NYSE during the ten trading day period ending on June 5, 2008, and based on the $31.61 average price per share of Willis common stock on the NYSE during the ten trading day period ending on August 21, 2008, the date of the proxy statement, the per share merger consideration was $46.00 per share and $46.00 per share, respectively. The implied value of the merger consideration will fluctuate with the market price of Willis�s common stock under certain circumstances described in the proxy statement/prospectus; however, the implied value of the merger consideration, based on a ten-day average pre-closing Willis common stock trading price, will be the same regardless of whether a HRH shareholder elects to receive cash or stock in exchange for their shares of HRH common stock. All elections are subject to the proration procedures provided in the merger agreement. As a result, HRH shareholders who elect to receive entirely cash or entirely Willis common stock may receive a combination of cash and common stock, and HRH shareholders who elect to receive a combination of cash and Willis common stock may receive cash and common stock in a different proportion from what they elected. Shareholders who do not submit a properly completed election form to Mellon by the election deadline will be deemed to have no preference as to the form of consideration they will receive and will receive cash, Willis shares of common stock or a combination of both, depending on the elections of other HRH shareholders. After HRH shareholders have made their elections and tendered their HRH shares of common stock to Mellon, they will be unable to sell or transfer their shares of HRH common stock unless they validly revoke their election prior to the election deadline. All of the documents necessary to make an election were previously mailed to HRH shareholders of record on or about August 27, 2008. HRH shareholders of record may obtain additional copies of the election documents by contacting the Information Agent, Georgeson Inc., toll-free at (888) 631-9679 or (212) 440-9800 from outside of the U.S. A more complete description of the merger consideration and the proration procedures applicable to elections is contained in the proxy statement/prospectus dated August 21, 2008, mailed to HRH shareholders of record on or about August 27, 2008. HRH shareholders are urged to read the proxy statement/prospectus carefully and in its entirety.
