Item 4. Description of Securities.

          Not applicable.

Item 5. Interests of Named Experts and Counsel.

          Not applicable.

Item 6. Indemnification of Directors and Officers.

          The Registrant is incorporated in Bermuda. The Bye-laws of the Registrant provide for indemnification of the Registrant’s officers and directors against all liabilities, loss, damage or expense incurred or suffered by such party as an officer or director of the Registrant; provided that such indemnification shall not extend to any matter which would render it void pursuant to the Companies Act of 1981 as in effect from time to time in Bermuda.

However, the Companies Act also provides that any provision, whether contained in the Company’s bye-laws or in a contract or arrangement between the Company and the director, indemnifying a director against any liability which would attach to him in respect of his fraud or dishonesty will be void. The

Item 9. Undertakings.

(a) The undersigned Registrant hereby undertakes:

(1) to file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:

(i)	to include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;
(ii)	to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information in the registration statement. Notwithstanding the foregoing, any increase or decrease in the volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Securities and Exchange Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and
(iii)	to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) above do not apply if the registration statement is on Form S-3, Form S-8 or Form F-3, and the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the Company pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the registration statement.

(2)	that, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new Registration Statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
(3)	to remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(b) The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act that is incorporated by reference in the Registration Statement shall be deemed to be a new Registration Statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

3

(c) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

          Pursuant to the requirements of the Securities Act of 1933, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-8 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized in the City of New York, State of New York, on this 1st day of October, 2008.

Dear Sirs

Willis Group Holdings Limited (the “Company”)

We have acted as legal counsel in Bermuda to the Company in connection with the preparation and filing of registration statement on Form S-8 filed by the Company with the United States Securities and Exchange Commission pursuant to the Securities Act of 1933 on 1 October 2008 (the “Registration Statement”), to register 3,849,181 of the Company’s common shares of par value US$0.000115 each (the “Shares”), to be issued and sold under the following plans (the “Plans”):

(i)	the Hilb, Rogal and Hamilton Company 2000 Stock Incentive Plan, as amended and restated February 11, 2003;
(ii)	the Hilb Rogal & Hobbs Company 2007 Stock Incentive Plan;
(iii)	the Hilb Rogal & Hobbs Company Non-employee Directors Stock Incentive Plan, as amended and restated effective January 1, 2007;
(iv)	the Hilb Rogal & Hobbs Company Executive Voluntary Deferral Plan, as amended and restated effective January 1, 2005; and
(v)	the Hilb Rogal & Hobbs Company Outside Directors Deferral Plan, as amended and restated effective January 1, 2007.

For the purposes of this opinion we have examined and relied upon the documents listed, and in some cases defined, in the Schedule to this opinion (the “Documents”).

Assumptions

In stating our opinion we have assumed:

(a) the authenticity, accuracy and completeness of all Documents examined by us submitted to us as originals and the conformity to authentic original documents of all Documents and other such documentation submitted to us as certified, conformed, notarised, faxed or photostatic copies;

Willis Group Holdings Limited

(b)	that each of the Documents which was received by electronic means is complete, intact and in conformity with the transmission as sent;
(c)	the genuineness of all signatures on the Documents;
(d)	the authority, capacity and power of each of the persons signing the Documents (other than the Company);
(e)	that any representation, warranty or statement of fact or law, other than as to the laws of Bermuda made in any of the Documents is true, accurate and complete;
(f)	that there are no provisions of the laws or regulations of any jurisdiction other than Bermuda which would be contravened by the issuance of the Shares which would have any implication in relation to the opinions expressed herein;
(g)	that the Resolutions are in full force and effect, have not been rescinded, either in whole or in part, and accurately record the resolutions passed by the Board of Directors of the Company in a meeting which was duly convened and at which a duly constituted quorum was present and voting throughout and that there is no matter affecting the authority of the Directors to effect the issue of the Shares and the filing by the Company of the Registration Statement, not disclosed by the Constitutional Documents or the Resolutions, which would have any adverse implication in relation to the opinions expressed herein;
(h)	that, when the Directors of the Company passed the Resolutions, each of the Directors discharged his fiduciary duties to the Company and acted honestly and in good faith with a view to the best interests of the Company;
(i)	that the records which were the subject of the Company Search were complete and accurate at the time of such search and disclosed all information which is material for the purposes of this opinion and such information has not since the date of the Company Search been materially altered; and
(j)	that the records which were the subject of the Litigation Search were complete and accurate at the time of such search and disclosed all information which is

Willis Group Holdings Limited
1 October 2008

material for the purposes of this opinion and such information has not since the date of the Litigation Search been materially altered.

Opinion

Based upon and subject to the foregoing and subject to the reservations set out below and to any matters not disclosed to us, we are of the opinion that:

(1) The Company is an exempted company incorporated with limited liability and existing under the laws of Bermuda. The Company possesses the capacity to sue and be sued in its own name and is in good standing under the laws of Bermuda.

(2) All necessary corporate action required to be taken by the Company in connection with the issue by the Company of the Shares pursuant to Bermuda law has been taken by or on behalf of the Company, and all necessary approvals of Governmental authorities in Bermuda have been duly obtained for the issue by the Company of the Shares.

(3) When issued pursuant to the Resolutions and delivered against payment therefor in the circumstances referred to or summarised in the Registration Statement and the Merger Agreement, the Shares will be validly issued, fully paid and non-assessable shares in the capital of the Company.

(4) There are no taxes, duties or other charges payable to or chargeable by the Government of Bermuda, or any authority or agency thereof in respect of the issue of the Shares.

Reservations

We have the following reservations:

(a) We express no opinion as to any law other than Bermuda law and none of the opinions expressed herein relates to compliance with or matters governed by the laws of any jurisdiction except Bermuda. This opinion is limited to Bermuda law as applied by the Courts of Bermuda at the date hereof.

1 October 2008

(b) Searches of the Register of Companies at the office of the Registrar of Companies and of the Supreme Court Causes Book at the Registry of the Supreme Court are not conclusive and it should be noted that the Register of Companies and the Supreme Court Causes Book do not reveal:

(i)	details of matters which have been lodged for filing or registration which as a matter of best practice of the Registrar of Companies or the Registry of the Supreme Court would have or should have been disclosed on the public file, the Causes Book or the Judgment Book, as the case may be, but for whatever reason have not actually been filed or registered or are not disclosed or which, notwithstanding filing or registration, at the date and time the search is concluded are for whatever reason not disclosed or do not appear on the public file, the Causes Book or Judgment Book;
(ii)	details of matters which should have been lodged for filing or registration at the Registrar of Companies or the Registry of the Supreme Court but have not been lodged for filing or registration at the date the search is concluded;
(iii)	whether an application to the Supreme Court for a winding-up petition or for the appointment of a receiver or manager has been prepared but not yet been presented or has been presented but does not appear in the Causes Book at the date and time the search is concluded;
(iv)	whether any arbitration or administrative proceedings are pending or whether any proceedings are threatened, or whether any arbitrator has been appointed; or
(v)	whether a receiver or manager has been appointed privately pursuant to the provisions of a debenture or other security, unless notice of the fact has been entered in the Register of Charges in accordance with the provisions of the Act.

Furthermore, in the absence of a statutorily defined system for the registration of charges created by companies incorporated outside Bermuda (“overseas

Page 4

Willis Group Holdings Limited

	companies”) over their assets located in Bermuda, it is not possible to determine definitively from searches of the Register of Charges maintained by the Registrar of Companies in respect of such overseas companies what charges have been registered over any of their assets located in Bermuda or whether any one charge has priority over any other charge over such assets.
(c)	In order to issue this opinion we have carried out the Company Search as referred to in the Schedule to this opinion and have not enquired as to whether there has been any change since the date of such search.
(d)	In order to issue this opinion we have carried out the Litigation Search as referred to in the Schedule to this opinion and have not enquired as to whether there has been any change since the date of such search.
(e)	In paragraph (1) above, the term “good standing” means that the Company has received a Certificate of Compliance from the Registrar of Companies.
(f)	Any reference in this opinion to shares being “non-assessable” shall mean, in relation to fully paid shares of the Company and subject to any contrary provision in any agreement in writing between such company and the holder of such shares, that no shareholder shall be bound by an alteration to the Memorandum of Association or Bye-laws of the Company after the date on which he became a shareholder, if and so far as the alteration requires him to take, or subscribe for additional shares, or in any way increases his liability to contribute to the share capital of, or otherwise to pay money to, the Company.

Disclosure

This opinion is addressed to you in connection with the filing by the Company of the Registration Statement with the United States Securities and Exchange Commission solely for the benefit of the Company and (save as referred to in the following paragraph), is not to be relied upon for any other purpose or quoted, or referred to in any public document, or filed with any governmental agency or person without our prior written consent, except as may be required by law.

We consent to the inclusion of this opinion as an exhibit to the Registration Statement.

This opinion speaks as of its date and is strictly limited to the matters stated herein and we assume no obligation to review or update this opinion if applicable law or the existing facts or circumstances should change.

This opinion is governed by and is to be construed in accordance with Bermuda law. It is given on the basis that it will not give rise to any legal proceedings with respect thereto in any jurisdiction other than Bermuda.

Yours faithfully
