Shire to Introduce a New UK Listed Holding Company

BASINGSTOKE, England and PHILADELPHIA, Pennsylvania, April 15 /PRNewswire-FirstCall/ -- THIS ANNOUNCEMENT IS AN ADVERTISEMENT AND NOT A PROSPECTUS AND INVESTORS SHOULD NOT SUBSCRIBE FOR OR PURCHASE ANY SECURITIES REFERRED TO IN THIS ANNOUNCEMENT EXCEPT ON THE BASIS OF INFORMATION TO BE CONTAINED IN THE PROSPECTUS EXPECTED TO BE PUBLISHED BY SHIRE LIMITED IN CONNECTION WITH THE PROPOSED SCHEME. THE PROSPECTUS WILL BE PUBLISHED AND MADE AVAILABLE ON SHIRE'S WEBSITE AND WILL BE AVAILABLE FOR INSPECTION AT THE UK LISTING AUTHORITY'S DOCUMENT VIEWING FACILITY

Shire plc ("Shire") (LSE: SHP, NASDAQ: SHPGY) announces a proposed Court sanctioned scheme of arrangement relating to the corporate structure and organisation of Shire, including the creation of a new UK listed, Jersey incorporated holding company for the group (the "Proposals").

The Proposals will not result in any changes in the day to day conduct of Shire's business, its strategy or dividend policy. The new holding company will have its primary listing on the London Stock Exchange ("LSE") and its American Depositary Shares ("ADS") will be traded on NASDAQ. It is not planned that the Proposals will result in any job losses or relocation of existing Shire personnel out of the UK.

Through a series of transactions over the last ten years, the Shire group's business has been transformed, from a primarily UK business to an international business, with the vast majority of its revenues generated from outside the UK. Shire has concluded that its business and its shareholders would be better served by having an international holding company with a group structure that is designed to help protect the group's taxation position, and better facilitate the group's financial management. The Directors believe that the most appropriate structure is for the new group parent company to be tax-resident in the Republic of Ireland.

The new holding company, which is to be called Shire Limited, will have the same Board and management team as Shire and there will be no substantive changes to corporate governance and investor protection measures. As is the case for Shire, Shire Limited will have its primary listing on the London Stock Exchange and, upon listing, will be included in FTSE's UK Index Series. Shire Limited also intends that its American Depositary Shares will be traded on NASDAQ, in place of Shire's existing ADS program.

Annual General Meeting

Assuming the Scheme becomes effective, this year's annual general meeting for the Shire group will be an annual general meeting of Shire Limited which is expected to be held in September.

Terms of the Scheme

Under the terms of a scheme of arrangement pursuant to sections 895 to 899 of the UK Companies Act 2006 (the "Scheme"), Shire Limited will issue Shire Limited ordinary shares to holders of Shire ordinary shares on a one-for-one basis. The Proposals do not involve any payment for the new ordinary shares.

The effect of the Proposals will therefore be as follows:

- Shire will become a subsidiary of Shire Limited (Shire Limited will be listed on the LSE in Shire's place);

- each Shire ordinary shareholder will own an identical number of new ordinary shares in Shire Limited as was owned in Shire; and

- Shire Limited's share capital will subsequently be reduced by a Jersey Court process to create distributable reserves.

It is expected that a Circular setting out full details of the Proposals will be sent to shareholders tomorrow, 16th April, 2008. A prospectus in relation to Shire Limited (the "Prospectus") will also be published and both documents will be available on Shire's website, http://www.shire.com.

ADS Holders

The ordinary shares underlying Shire ADSs will participate in the Scheme, if approved, like all other ordinary shares in Shire. In conjunction with the Scheme, Shire ADSs will become Shire Limited ADSs on a one-for-one basis, without any action being required on the part of Shire ADS holders, and with each Shire Limited ADS representing three ordinary shares in Shire Limited. The Proposals do not involve any payment for the new ADSs. It is intended that the Shire Limited ADSs will be traded on NASDAQ in place of the Shire ADSs.

Income Access Share Arrangements

Shire Limited intends to put into place, after completion of the Scheme and subject to the passing of a board resolution by Shire Limited, income access share arrangements.

If these arrangements are adopted, then for so long as they remain in operation:

- Shire Limited ordinary shareholders, other than ADS holders, will be able to choose whether they receive their dividends from a company resident for tax purposes in the UK (i.e. Shire) or from a company resident for tax purposes in the Republic of Ireland (i.e. Shire Limited);

- The ADS depositary will be required to elect on behalf of all holders of Shire Limited ADSs to receive their dividends from a company resident for tax purposes in the UK (i.e. Shire);

- Shire Limited ordinary shareholders who hold 25,000 or fewer Shire Limited ordinary shares at the time the Scheme becomes effective, and who do not make a contrary election, will be deemed to have elected to receive their dividends from a company resident for tax purposes in the UK (i.e. Shire); and

- Shire Limited ordinary shareholders who acquire their Shire Limited ordinary shares after the Scheme becomes effective, who hold 25,000 or fewer Shire Limited ordinary shares on the first dividend record date after they become Shire Limited ordinary shareholders and who do not make a contrary election, will be deemed to have elected to receive their dividends from a company resident for tax purposes in the UK (i.e. Shire).

Issuer Substitution under Shire's Convertible Bonds

In connection with the Scheme, Shire Limited will be substituted in place of Shire, with effect from immediately prior to the Scheme becoming effective, as principal obligor under the US$1,100 million 2.75 per cent. convertible bonds due 2014 originally issued by Shire on 9 May 2007. On and from such substitution, the bonds will be convertible into ordinary shares of Shire Limited.

Conditions to the Implementation of the Proposals

The Scheme will require the approval of Shire ordinary shareholders at a shareholder meeting to be convened at the direction of the High Court (the "Court Meeting"). The approval required at the Court Meeting is a majority in number of Shire ordinary shareholders present and voting (whether in person or by proxy) representing not less than 75% in value of those Shire ordinary shareholders who vote at the meeting.

The Scheme will also require separate approval by not less than 75% of all Shire shareholders who vote (whether in person or by proxy) at an extraordinary general meeting of Shire (the "EGM").

In addition to the approvals mentioned above, the Scheme will be conditional upon the sanction of the Scheme by the High Court. The subsequent reduction of capital of Shire Limited will also require approval at a later hearing of the Royal Court of Jersey.

This timetable is based on the Board's expectations and may be subject to change. Any changes to the timetable will be the subject of a further announcement. Key dates relevant to the holders of Shire ADSs may differ from those above and will be set out in full in the Circular.

Morgan Stanley & Co. International plc is acting as sponsor to Shire Limited's listing and as joint corporate broker. Deutsche Bank AG London is acting as joint corporate broker.
