Item 1.01. Entry into a Material Definitive Agreement. On April 8, 2005, Willis Group Holdings Limited ("Willis"), Willis North America Inc. and Willis of New York, Inc. (collectively, the "Company") entered into an Assurance of Discontinuance (the "AOD") with the Attorney General of the State of New York and the Superintendent of Insurance of the State of New York (collectively, the "NY State Agencies") to resolve all of the issues related to investigations conducted by the State Agencies. As part of the AOD, Willis has agreed to continue a number of practices that Willis had adopted previously. These include the ban on contingent commissions, which Willis announced in October 2004, as well as the implementation of a number of practices reflected in the Willis Client Bill of Rights that Willis issued in July 2004. The material terms of the AOD are as follows: 1. On or before July 1, 2005, Willis North America will pay $50 million into a fund (the "Fund") to be distributed to certain eligible policyholder clients. These payments are in full satisfaction of the Company's obligations under the AOD and the NY State Agencies have agreed not to impose any other financial obligation or liability on the Company in connection with their investigations. No portion of the payments by the Company is considered a fine or penalty. 2. The Fund, plus interest, will be used to compensate the Company's eligible policyholder clients according to procedures set out in the AOD. No amount paid to the Fund will be returned to the Company under any circumstances. 3. On or before July 31, 2005, the Company will calculate, in accordance with a formula approved by the Attorney General, the amount that each policyholder client is eligible to receive from the Fund. Clients eligible to participate in the Fund are those U.S. clients that engaged the Company to place, renew, consult on or service insurance with inception or renewal dates between January 1, 2001 through December 31, 2004 (the "Relevant Period") where such placement, renewal, consultation or servicing resulted in contingent commissions or overrides recorded by Willis during the Relevant Period (the "Eligible Policyholders"). 4. On or before August 20, 2005, the Company must send a notice to each Eligible Policyholder setting forth, among other things, the amount it will be paid from the Fund if it elects to participate (a "Participating Policyholder"). Participating Policyholders must tender a release of claims against the Company arising from acts, omissions, transactions or conduct that are the subject of the investigations by the NY State Agencies. 5. On February 1, 2006, each Participating Policyholder shall receive from the Fund as much of that Participating Policyholder's aggregate share of the Fund as possible with the monies then available in the Fund.

6. In the event that an Eligible Policyholder elects not to participate or otherwise does not respond by December 20, 2005 (a "Non-Participating Policyholder"), that client's allocated share may be used by the Company to satisfy any pending or other claims asserted by clients relating to the matters covered by the AOD. In no event shall a distribution be made from the Fund to any other client until all Participating Policyholders have been paid, nor shall total payments to any Non-Participating Policyholder exceed 80% of that policyholder's original allocated share. If any funds remain in the Fund as of February 20, 2006 such funds shall be distributed pro rata to the Participating Policyholders. 7. In no event shall any of the amounts paid into the Fund be used to pay attorneys' fees. 8. Within 60 days of the date of the AOD, the Company shall commence the implementation, to the extent not already undertaken, of certain business reforms, including the following: o To accept only a specific fee to be paid by the client, a specific percentage commission on premium to be paid by an insurer set at the time of purchase, renewal, placement or servicing of an insurance policy, or a combination of both. o To fully disclose in plain, unambiguous written language commissions in either dollars or percentage amounts. o Not to accept any other valuable compensation or consideration from an insurer other than as stated above, including contingent compensation and any compensation or preference in connection with the selection of insurers from which to solicit bids for clients. o Not to request or accept from any insurer any false, fictitious or inflated quote, or quote that does not represent the insurers' best evaluation at the time of the minimum premium the insurer would require to bind the insurance coverage sought by the client. o Not to request or accept from any insurer any promise or commitment for the use of our services, including reinsurance brokerage, agency or producing services, conditioned upon any arrangement to provide preferential treatment for any insurer. o Not to place, renew or service a client's business through a wholesale broker unless agreed to by the client after full disclosure of all the compensation to be received, any interest or contractual agreements we may have in the wholesale broker, and any alternative to using the wholesaler broker. o To fully disclose to each client all quotes received in connection with coverage of the client's risk with all terms and all commissions to be received for each quote, and to provide disclosure of and obtain clients written consent to all compensation arrangements.

o To disclose to each client at the end of each year all compensation received during the preceding year from any insurer or third party in connection with the client's policy. o To implement company-wide written standards of conduct regarding compensation from insurers consistent with the terms of the AOD and institute appropriate training of employees, including business ethics, professional obligations, conflicts of interest, antitrust and trade practices compliance and record keeping. o To establish a Compliance Committee of our Board of Directors that will monitor our compliance with the standards of conduct regarding compensation. o To maintain a record of all complaints regarding compensation from any insurer, and provide such record to the Compliance Committee. o To file annual reports with Superintendent for five years. 9. The Company shall not, directly or indirectly, seek or accept indemnification pursuant to any insurance policy with respect to any amounts payable under the AOD. The foregoing summary is qualified in its entirety by reference to the AOD. Also on April 8, 2005, the Willis announced that it had entered into an Assurance of Discontinuance with the Minnesota Attorney General (the "MN AOD"). Under the MN AOD, Willis North America will make an additional $1 million payment in a manner directed by the Minnesota Attorney General to clients who are located, headquartered or have a principle place of business in the State of Minnesota and that were clients of the Company at any time from January 1, 2001 to December 31, 2004. These payments are in addition to the payments to be made by the Company under the simultaneously executed national agreement with the New State Agencies. Willis also agreed to reforms that include additional disclosures to clients and greater transparency in insurance transactions. The foregoing summary is qualified in its entirety by reference to the MN AOD. Item 8.01. Other Events.

Willis Reaches Agreement with New York Attorney General and New York Insurance
Department; USD50 Million Resolution Reached Without AG Bringing Lawsuit

     NEW YORK--(BUSINESS WIRE)--April 8, 2005--Willis Group Holdings (NYSE: WSH)
has reached a comprehensive agreement with the New York Attorney General and the
Superintendent of Insurance for New York to resolve issues raised by the
industry-wide investigation into contingent commissions.
     Willis is the only insurance broker to resolve these matters with the New
York Attorney General without the commencement of a lawsuit against the company,
and is also the only broker to resolve these matters without being required to
issue an apology.
     Joe Plumeri, Chairman and Chief Executive Officer of Willis Group Holdings,
said: "Willis is pleased to have resolved this matter with the New York Attorney
General and the New York Insurance Superintendent, and we welcome the Attorney
General's conclusion that it was not appropriate to file a complaint against our
company based on the findings of his investigation. We also are pleased that the
investigation found no evidence of the practice of bid-rigging or tying.
     "We appreciate the comments of Attorney General Spitzer," said Plumeri.
     "Willis moved quickly to remedy its problems," said Attorney General
Spitzer. "Its actions will help bring about greater transparency and
accountability in the insurance industry. Willis chairman Joseph Plumeri has
demonstrated admirable leadership in spearheading Willis's response to the
issues raised in our investigation and in implementing reforms at the company."
     Plumeri continued, "We believe that the regulatory investigations have been
a catalyst for positive change in the industry. We strongly support the reforms
that the Attorney General has advocated, and we previously had voluntarily
implemented many as part of our Client Bill of Rights. We also were the first
major broker in the industry to end the use of contingents, which we have
abolished on a worldwide basis, and we believe that all insurance brokers and
insurers should relinquish the use of contingent agreements."
     The company agreed to an Assurance of Discontinuance (AOD), under which
Willis will create a USD50 million fund, prior to July 1, 2005, to compensate
U.S. clients who retained Willis to place insurance between January 1, 2001 and
December 31, 2004, which resulted in contingent commissions. No portion of the
fund represents a fine or a penalty, and Willis admitted no wrongdoing or
liability.
     As part of the AOD, Willis has agreed to continue a number of practices
that Willis had adopted previously. These include the ban on contingent
commissions, which Willis announced in October 2004, as well as the
implementation of a number of practices reflected in the Willis Client Bill of
Rights that Willis issued in July 2004, including:

     --   Always acting in the best interest of the client;

     --   Fully disclosing all compensation that Willis receives for its
          services, which the company has been doing since January 2005;

     --   Providing enhanced training for its Associates on their duty of care
          to clients, which began in November 2004;

     --   Prohibiting Associates from accepting compensation, gifts,
          entertainment or trips from insurers, a policy which was formalized in
          July 2004; and,

     --   Enforcing these principles through rigorous internal controls and
          compliance reviews.

     Mr. Plumeri added: "The agreement that we are announcing today recognizes
the material differences between Willis' conduct and that of our major
competitors. We intend to continue the commitment to reform and transparency
that distinguishes us in the marketplace."
     Today at noon, Eastern Time, Mr. Plumeri will host a conference call to
discuss the agreement. Interested parties may access the conference call by

Minnesota Attorney General and Willis Group Holdings Resolve Insurance
Investigation

     NEW YORK--(BUSINESS WIRE)--April 8, 2005--Minnesota Attorney General Mike
Hatch and Willis Group Holdings, Ltd. Chairman and CEO Joe Plumeri today
announced an agreement relating to Willis' insurance brokerage practices.
     Under the agreement, Willis will make payments to its Minnesota clients of
an additional USD1 million on top of the payments to be made by Willis under a

Office and the New York Superintendent of Insurance. Willis also agreed to
reforms that include additional disclosures to clients and greater transparency
in insurance transactions.
     Joe Plumeri, Chairman and Chief Executive Officer of Willis Group Holdings,
said: "Willis is pleased to have resolved this investigation with Attorney
General Hatch and to put it behind our company. Through his direct, personal
involvement, Attorney General Hatch brought to our attention a number of
concerns, which we have addressed. Willis was the first major broker in the
industry to end the use of contingents. We believe that all insurance brokers
and insurers should relinquish the use of contingent agreements."
     "We are pleased to have reached this agreement with Willis. I commend Mr.
Plumeri for coming to Minnesota to discuss these issues with me directly and,
through his hands-on involvement, forging this agreement," said Hatch.
     Under the terms of the agreement, Willis will be contacting by letter
Minnesota policyholders who may be eligible for payments.
     The agreement between Willis and Minnesota Attorney General Hatch resolves
the issues raised in the Attorney General's March 8, 2005 court filings. Under
