Item 1.01 Entry into a Material Definitive Agreement. As previously announced, on July 26, 2006, the Board of Directors of Willis Group Holding Limited ("Willis") authorized the repurchase of up to $1.0 billion of Willis' common shares. Purchases may be made from time to time in the open market or through negotiated sales with persons who are not affiliates of Willis. After the transaction described below, Willis remains authorized to repurchase from time to time up to $789 million of its shares pursuant to the pre-existing authority. Pursuant to that authorization, on November 16, 2006, Willis entered into an accelerated share repurchase agreement (the "Confirmation") with Lehman Brothers Finance S.A. ("Lehman Brothers") to purchase from Lehman Brothers approximately 3.8 million shares of its common stock pursuant to a private transaction for an initial aggregate purchase price of $150 million. Under the Confirmation dated November 16, 2006, which contains the principal terms and provisions governing the program between Willis and Lehman Brothers, the repurchased shares are subject to a price adjustment based on the volume weighted average share price ("VWAP") of Willis' common stock during the term of the program. Willis expects the program to be completed in February of 2007, although in certain limited circumstances the completion date may be accelerated or delayed. The repurchased shares will be recorded as a reduction in shareholders' equity on Willis' Consolidated Balance Sheet and will be retired on or before the completion of the program. In addition, the Confirmation contains other terms governing the program, including, but not limited to, the mechanism used to determine the final settlement of the transaction, the settlement method, the specific circumstances under which Lehman Brothers is permitted to make adjustments to valuation periods, the specific circumstances under which the program may be terminated early (including mergers, tender offers, and certain other events), definitions of terms used throughout the Confirmation, and various acknowledgements, representations and warranties made by Willis and Lehman Brothers to one another, including representations related to Rule 10b5-1 and intended compliance with the Rule 10b-18 volume and timing guidelines. In certain circumstances, Willis may receive from, or be required to pay, Lehman Brothers a termination payment in the event of an early termination. In the ordinary course of their business, Lehman Brothers and its affiliates have engaged, and may in the future engage, in financial advisory and/or investment banking transactions with Willis and its affiliates. They have received and will receive customary fees and commissions for these transactions. Item 7.01 Regulation FD Disclosure. On November 16, 2006, Willis issued a press release announcing the Confirmation. This press release is furnished as Exhibit 99.1 hereto. The information contained in Exhibit 99.1 is being furnished pursuant to Item 7.01 of this Current Report on Form 8-K, and shall not be deemed to be "filed" for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or otherwise subject to the liabilities under Section 18. Furthermore, the information contained in Exhibit 99.1 shall not be deemed to be incorporated by reference into the filings of Willis under the Securities Act of 1933, as amended, or the Exchange Act.

                    Willis Group Holdings Limited Announces
         Accelerated Share Repurchase of $150 Million of Common Shares


     NEW YORK--(BUSINESS WIRE)--Nov. 16, 2006--Willis Group Holdings Limited
(NYSE: WSH), the global insurance broker, today announced that it has entered
into an agreement to purchase approximately 3.8 million shares of its common
stock from an affiliate of Lehman Brothers, Inc. using an accelerated stock
repurchase program for an initial purchase price of $150 million. This
repurchase is part of Willis' previously announced stock repurchase program.

     "With significant financial flexibility, we are always considering how best
to manage and utilize our capital to serve the best interests of our
shareholders," said Joe Plumeri, Chairman and Chief Executive Officer Willis.
"This element of our stock repurchase program is one of the levers we have at
our disposal; it is both an economically attractive manner for us to deploy our
available cash while at the same time continuing to build shareholder value."

     Under the terms of the arrangement, the repurchased shares are subject to a
price adjustment based on the volume weighted average market price of Willis'
common shares during the term of the program. The Company expects the program to
be completed in the first quarter of 2007. All of the shares repurchased under
the agreement will be retired.

     Including this transaction, the company expects to repurchase 5.4 million
shares for $211 million during fiscal year 2006 and would have $789 million of
authorized share repurchases remaining under its existing buyback authorization.
