Overseas jurisdictions

The availability of the Acquisition to JLT Shareholders who are not resident in and citizens of the UK may be affected by the laws of the relevant jurisdictions in which they are located or of which they are citizens. Persons who are not resident in the UK should inform themselves of, and observe, any applicable legal or regulatory requirements of their jurisdictions. Further details in relation to Overseas Shareholders will be contained in the Scheme Document.

The release, publication or distribution of this announcement in jurisdictions other than the United Kingdom may be restricted by law and therefore any persons who are subject to the laws of any jurisdiction other than the United Kingdom should inform themselves about, and observe any applicable requirements. Any failure to comply with the applicable restrictions may constitute a violation of the securities laws of any such jurisdiction. To the fullest extent permitted by applicable law, the companies and persons involved in the Acquisition disclaim any responsibility or liability for the violation of such restrictions by any person. This announcement has been prepared for the purpose of complying with English law and the City Code and the information disclosed may not be the same as that which would have been disclosed if this announcement had been prepared in accordance with the laws of jurisdictions outside the United Kingdom.

Copies of this announcement and any formal documentation relating to the Acquisition are not being, and must not be, directly or indirectly, mailed or otherwise forwarded, distributed or sent in or into or from any Restricted Jurisdiction and persons receiving such documents (including custodians, nominees and trustees) must not mail or otherwise forward, distribute or send it in or into or from any Restricted Jurisdiction. If the Acquisition is implemented by way of an Offer (unless otherwise permitted by applicable law and regulation), the Offer may not be made directly or indirectly, in or into, or by the use of mails or any means or instrumentality (including, but not limited to, facsimile, e-mail or other electronic transmission, telex or telephone) of interstate or foreign commerce of, or of any facility of a national, state or other securities exchange of any Restricted Jurisdiction and the Offer may not be capable of acceptance by any such use, means, instrumentality or facilities.

US holders of JLT Shares should note that the Acquisition relates to the shares of an English company and is being made by means of a scheme of arrangement provided for under English company law. An acquisition effected by means of a scheme of arrangement is not subject to the tender offer rules or the proxy solicitation rules under the US Exchange Act. Accordingly, the Acquisition is subject to the disclosure requirements and practices applicable in the United Kingdom to schemes of arrangement which differ from the disclosure requirements of United States tender offer and proxy solicitation rules. If, in the future, MMC BidCo exercises the right to implement the Acquisition by way of an Offer and determines to extend the Offer into the United States, the Acquisition will be made in compliance with applicable United States laws and regulations. Financial information included in this announcement and the Scheme Documentation has been or will have been prepared in accordance with accounting standards applicable in the United Kingdom that may not be comparable to financial information of US companies or companies whose financial statements are prepared in accordance with generally accepted accounting principles in the United States.

It may be difficult for US holders of JLT Shares to enforce their rights and any claim arising out of the US federal laws, since MMC BidCo and JLT are located in a non-US jurisdiction, and some or all of their officers and directors may be residents of a non-US jurisdiction. US holders of JLT Shares may not be able to sue a non-US company or its officers or directors in a non-US court for violations of the US securities laws. Further, it may be difficult to compel a non-US company and its affiliates to subject themselves to a US court's judgement.

The receipt of cash pursuant to the Acquisition by US holders of JLT Shares as consideration for the transfer of its Scheme Shares pursuant to the Scheme may be a taxable transaction for US federal income tax purposes and under applicable US state and local, as well as foreign and other, tax laws. Each US holder of JLT Shares is urged to consult his independent professional adviser immediately regarding the tax consequences of the Acquisition applicable to him.
