Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 5(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) In accordance with that certain Escrow Agreement, dated as of January 18, 2012 (the "Escrow Agreement"), among Jazz Pharmaceuticals plc (the "Issuer"), Jazz Pharmaceuticals, Inc., the Reporting Person, as representative of the indemnitors, and Deutsche Bank National Trust Company, as escrow agent, 10% of these ordinary shares are subject to an escrow and are held by the escrow agent as security for the indemnification obligations under that certain Agreement and Plan of Merger and Reorganization, dated as of September 19, 2011 (the "Merger Agreement"), by and among the Issuer (formerly known as Azur Pharma Limited), Jazz Pharmaceuticals Inc., Jaguar Merger Sub Inc. and the Reporting Person, as representative of the indemnitors (as defined therein).
(2) The shareholders owning ordinary shares subject to the escrow, including the Reporting Person, have the right to vote the escrowed ordinary shares and to receive all dividends on the escrowed ordinary shares, other than certain dividends paid in capital stock of the Issuer. Any shares of capital stock of the Issuer issuable in respect of or in exchange for any escrowed ordinary shares, whether by way of share splits, dividends, or otherwise, will be issued in the name of the escrow agent and held under the escrow agreement, subject to certain exceptions. The shareholders owning ordinary shares subject to such escrow, including the Reporting Person, are also entitled to remove their ordinary shares from the escrow account provided they replace the removed ordinary shares with cash having an equivalent value.
(3) The escrow agent is permitted to sell ordinary shares held in the escrow account for the purpose of satisfying indemnification claims that may arise from time to time upon receipt of proper instructions and direction pursuant to the terms of the Escrow Agreement. Subject to the existence of any pending claims, ordinary shares retained in the escrow account as of July 18, 2013, the termination date for the escrow, will be released to the respective owners thereof. If there are unresolved indemnification claims as of the termination date, the escrow agent will retain a number of ordinary shares in escrow having a value sufficient to cover the amount of such pending claims until such claims are resolved. The escrow agent may not sell or otherwise dispose of ordinary shares held in the escrow account other than as described above or pursuant to joint written instructions of Jazz Pharmaceuticals, Inc. and the Reporting Person, as indemnitors' representative.
(4) The Reporting Person has entered into agreements to transfer 72,080 ordinary shares at a purchase price of two hundred Euros (EUR 200) and 360,397 ordinary shares at a purchase price of one thousand Euros (EUR 1,000) at some mutually agreeable time prior to December 31, 2013, to Barrymore Trust, a family discretionary trust, the beneficiaries of which are the Reporting Person, his wife and his children.
(5) Represents shares that are held by the Reporting Person on behalf of his wife, Deirdre Mallon. Ms. Mallon has also agreed to transfer, prior to December 31, 2013, 432,477 ordinary shares to the family discretionary trust.
(6) Represents shares that are held by the Reporting Person in trust for nineteen other individuals. The Reporting Person exercises sole voting, but no dispositive power, over these shares. Except for the Reporting Person's voting interest with respect to these shares, the Reporting Person disclaims all beneficial ownership of these securities.
