A. General questions on the Transaction and structure

1. What is happening? / What is the Scheme of Arrangement between GW and Jazz?

GW and Jazz announced on the 3^rd of February 2021 that they had entered into a definitive agreement for Jazz Pharmaceuticals UK Holdings Limited, or “Bidco”, a wholly-owned subsidiary of Jazz, to acquire GW. The Transaction is to be effected by means of a scheme of arrangement under Part 26 of the Companies Act, the details for which you will find in the proxy statement.

The GW Shareholder Meetings will be held on 23 April 2021. The GW Shareholder Meetings will consist of (1) a Court Meeting to consider and vote on the Scheme of Arrangement, which is convened with the permission of the High Court of England and Wales, and which will be immediately followed by (2) a General Meeting of the GW shareholders.

The Transaction is conditional on, among other things, GW shareholders approving the Scheme of Arrangement at the Court Meeting and, at the General Meeting, approving the resolution to (i) authorize the GW board of directors to take all action necessary or appropriate for carrying the Scheme of Arrangement into effect and (ii) make certain amendments to the GW Articles of Association.

Under the terms of the agreement, holders of GW ordinary shares will be entitled to receive sixteen point six-six and two-thirds dollars ($16.66 2/3) for each GW ordinary share, plus an amount of Jazz ordinary shares determined by the exchange ratio [Agent to refer to Question 12].

2. What is a Scheme of Arrangement?

A “scheme of arrangement” is a court-sanctioned arrangement between an English company (such as GW) and its shareholders under Part 26 of the Companies Act, which can be used as a transaction structure to effect an acquisition, takeover or other business combination.

A scheme of arrangement enables a buyer to acquire the entire issued share capital of a target company if the scheme of arrangement has been approved by the requisite majorities of the target company’s shareholders and the scheme of arrangement has been sanctioned by the Court.

3. What are the Shareholder Meetings? / What am I being asked to vote on?

GW is holding two separate shareholder meetings in connection with the Transaction:

Court Meeting: In order for the Scheme of Arrangement to become effective, the Scheme of Arrangement must, among other requirements, be approved by the requisite majorities of Scheme Shareholders. This approval is to be obtained at the Court Meeting, which is convened with the permission of the High Court of England and Wales. The purpose of the Court Meeting is to allow the Court to ascertain whether Scheme Shareholders are in favour of the Scheme of Arrangement.

General Meeting: In addition to the approval of the Scheme of Arrangement at the Court Meeting, the following additional resolutions regarding the Transaction are proposed to be approved at the General Meeting:

• The Scheme Implementation Proposal to (i) authorize the GW board of directors to take all action necessary or appropriate for carrying the Scheme of Arrangement into effect and (ii) make certain amendments to the GW Articles of Association in order to facilitate the Transaction; and

• The Non-Binding Advisory Proposal to Approve Certain Compensation Arrangements which approves, on an advisory, non-binding basis, the compensation that may be paid or become payable to GW’s named executive officers in connection with the Transaction.

4. Why did I receive two forms of proxy? (ORD Holders)

Each registered holder of GW ordinary shares has been sent a blue form of proxy for use in respect of the Court Meeting and a yellow form of proxy for use in respect of the General Meeting. If you have not received two forms of proxy, please contact the registrar Link Group at +44 371 664 0321.

General Meeting

GW shareholders are also being asked to consider and approve the Scheme Implementation Proposal and the Non-Binding Advisory Proposal to Approve Certain Compensation Arrangements at the General Meeting.

The Scheme Implementation Proposal will be proposed as a special resolution at the General Meeting, which means that the Scheme Implementation Proposal must be approved by at least 75% of the votes cast by GW ordinary shareholders present and voting (and entitled to vote), either remotely or by proxy.

The Non-Binding Advisory Proposal to Approve Certain Compensation Arrangements will be proposed as an ordinary resolution at the General Meeting, which means that the Non-Binding Advisory Proposal to Approve Certain Compensation Arrangements must be approved by a simple majority of the votes cast by GW ordinary shareholders present and voting (and entitled to vote), either remotely or by proxy.

14. What happens if I am eligible to receive a fraction of a Jazz ordinary share?

If you make a valid currency election to receive cash consideration in British pounds instead of US dollars, any cash in lieu of fractional Jazz ordinary shares will also be paid in British pounds.

Actual results and the timing of events could differ materially from those anticipated in such forward-looking statements as a result of these risks and uncertainties, which include, without limitation, risks and uncertainties associated with GW’s and Jazz’s ability to complete the acquisition on the proposed terms or on the anticipated timeline, or at all, including: risks and uncertainties related to securing the necessary regulatory and shareholder approvals, the sanction of the High Court of Justice of England and Wales and satisfaction of other closing conditions to consummate the acquisition; the occurrence of any event, change or other circumstance that could give rise to the termination of the definitive transaction agreement relating to the acquisition; risks related to diverting the attention of GW and Jazz management from ongoing business operations; failure to realize the expected benefits of the acquisition; significant transaction costs and/or unknown or inestimable liabilities; the risk of shareholder litigation in connection with the acquisition, including resulting expense or delay; the risk that GW’s business will not be integrated successfully or that such integration may be more difficult, time-consuming or costly than expected; Jazz’s ability to obtain the expected financing to consummate the acquisition; risks related to future opportunities and plans for the combined company, including the uncertainty of expected future regulatory filings, financial performance and results of the combined company following completion of the acquisition; GW’s or the combined company’s dependence on the successful commercialization of Epidiolex or Epidyolex (the trade name for Epidiolex in Europe) and the uncertain market potential of Epidiolex/Epidyolex; pharmaceutical product development and the uncertainty of clinical success; the regulatory approval process, including the risks that GW or Jazz may be unable to submit anticipated regulatory filings on the timeframe anticipated, or at all, or that GW or the combined company may be unable to obtain regulatory approvals of any product candidates, including nabiximols and Epidiolex/Epidyolex for additional indications, in a timely manner or at all; disruption from the acquisition, making it more difficult to conduct business as usual or maintain relationships with customers, employees, distributors, suppliers or other third parties; effects relating to the announcement of the acquisition or any further announcements or the consummation of the acquisition on the market price of Jazz ordinary shares, GW American depositary shares or GW ordinary shares; the possibility that, if Jazz does not achieve the perceived benefits of the acquisition as rapidly or to the extent anticipated by financial analysts or investors, the market price of Jazz ordinary shares could decline; regulatory initiatives and changes in tax laws; market volatility; and other risks and uncertainties affecting GW and Jazz, including those described from time to time under the caption “Risk Factors” and elsewhere in GW’s and Jazz’s U.S. Securities and Exchange Commission (the “SEC”) filings and reports, including GW’s Annual Report on Form 10-K for the fiscal year ended December 31, 2020, Jazz’s Annual Report on Form 10-K for the fiscal year ended December 31, 2020, GW’s definitive proxy statement filed with the SEC on March 15, 2021 and future filings and reports by either company. In addition, while GW and Jazz expect the COVID-19 pandemic to continue to adversely affect their respective business operations and financial results, the extent of the impact on the combined company’s ability to generate sales of and revenues from its approved products, execute on new product launches, its clinical development and regulatory efforts, its corporate development objectives and the value of and market for its ordinary shares, will depend on future developments that are highly uncertain and cannot be predicted with confidence at this time.
