2018 Pay-for-Performance
Overview

A significant portion of target total direct compensation for our CEO and other NEOs is structured in the form of
at-risk compensation, consisting of annual performance bonus and equity incentive awards, with the performance bonus payouts and equity award values dependent upon our company performance. This
aligns our executives interests with those of our shareholders for near- and long-term performance. Target total direct compensation for 2018, as shown below, reflects annual base salary paid, annual target performance bonus, the cash signing
bonus Mr. Swisher received in connection with his appointment as President and COO and the grant date fair value of equity awards granted during the year (as such equity awards are reported in the Summary Compensation Table).

Compensation Philosophy and Objectives

Our executive compensation program is designed with the following objectives and philosophy:



| |  | Attract, incentivize, reward and retain diverse, talented individuals with relevant experience in the life sciences
industry through a competitive pay structure. We reward individuals fairly over time and seek to retain those individuals who continue to meet our high expectations.
|- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | Deliver balanced total compensation packages to accomplish our business objectives and mission.Our executive
compensation program focuses on total compensation, combining short- and long-term components, cash and equity, and fixed and variable payments, in the proportions that we believe are the most appropriate to incentivize and reward our
executive officers for achieving our corporate goals while minimizing incentives for excessive risk-taking or unethical conduct.
|- |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | Align pay with our performance.Our annual bonus awards are not earned unless
pre-determined levels of performance are achieved against annual corporate objectives approved by our board of directors at the beginning of the year. Likewise, our stock option awards will not provide
realizable value and our restricted stock unit, or RSU, awards will not provide increased value unless there is an increase in the value of our shares, which benefits all shareholders. We also have executive share ownership guidelines to further
support our ownership culture and align the interests of executive officers and shareholders.

How We Determine
Executive Compensation

Role of Our Compensation Committee and Executive Officers

The compensation committee is (and was at all times during 2018) composed entirely of independent directors, as defined by Rule 5605(a)(2) of the Nasdaq listing
standards. Our compensation committee meets as often as it determines necessary to carry out its duties and responsibilities through regularly scheduled meetings and, if necessary, special meetings. Our compensation committee also has the authority
to take certain actions by written consent of all members. The agenda for each compensation committee meeting is usually developed by members of our human resources department and our CEO, with input from members of our legal department, and is
reviewed and finalized with the chairperson of the compensation committee. In 2018, the compensation committee met six times and did not act by unanimous written consent. As of the date of this report, in 2019, the compensation committee has met
twice and has not acted by unanimous written consent.

##### Table of Contents

The compensation committee reviews and oversees our compensation policies, plans and programs and reviews and generally
determines the compensation to be paid to the executive officers, including the NEOs. Either the compensation committee or the independent members of our board of directors, upon recommendation from the compensation committee, who receives input and
advice from its independent compensation consultant, approve the compensation of our CEO. References in this Compensation Discussion and Analysis to our board of directors approving our CEOs compensation are to the independent members of our
board of directors. The compensation committee does not delegate any of its functions to others in determining executive compensation.

In making other executive
compensation determinations, the compensation committee considers recommendations from our CEO. In making his recommendations, our CEO receives input from our human resources department and from the individuals who manage or report directly to the
other executive officers, and he reviews various third party compensation surveys and compensation data provided by the independent compensation consultant to the compensation committee, as described below. While our CEO discusses his
recommendations for the other executive officers with the compensation committee, he does not participate in the deliberations and recommendations to our board of directors concerning, or our board of directors determination of, his own
compensation. Members of our human resources and legal departments also attend compensation committee meetings.

Below are the highlights of the annual cycle our
compensation committee follows in reviewing and making decisions with respect to our executive compensation program.

Role of the Independent Compensation Consultant

The compensation committee engages an independent compensation consultant each year to provide a competitive compensation assessment with respect to the executive
officers to assist the compensation committee in making annual compensation decisions. Since 2010, Radford, a business area within Aon plc, has been engaged by the compensation committee each year to provide peer company and industry compensation
data and provide the compensation committee with advice regarding executive officers compensation, including base salaries, performance-based bonuses and long-term equity compensation, and similar advice regarding non-employee directors compensation. The compensation committee has also consulted with Radford to update the peer company and industry compensation data on an annual basis and as needed with respect to
specific questions that arise and on an advisory basis with respect to addressing other responsibilities arising under the compensation committee charter, including trends and best practices regarding executive compensation and compensation
committees, in order to help inform the compensation committees decisions. Radford reports directly to the compensation committee, which maintains the authority to direct Radfords work and engagement, and advises the compensation
committee and our human resources department on projects from time to time. Radford interacts with management to gain access to company information that is required to perform services and to understand the culture and policies of the organization.
Radford attends compensation committee meetings, and the compensation committee and Radford meet in executive session with no members of management present, as needed, to address various compensation matters, including deliberations regarding our
CEOs compensation.

In assessing Radfords independence from management in providing executive compensation services to the compensation committee, the
compensation committee considered that Radford is only engaged by, takes direction from, and reports to, the compensation committee for such services and, accordingly, only the compensation committee has the right to terminate or replace Radford as
its compensation consultant at any time. The compensation committee also analyzed whether the work of Radford as a compensation consultant with respect to executive and director compensation raised any conflict of interest, taking into consideration
the following factors:



|  |  |                                                                                                                                                    |  |  |  |   |  |

The compensation committee has determined, based on its analysis of the above factors, that the work of Radford and the
individual compensation advisors employed by Radford as compensation consultants to our company has not created any conflict of interest.

Competitive Assessment of Compensation  Peer Companies and Market Data

Because we aim to attract and retain the most highly qualified executive
officers in an extremely competitive market, the compensation committee believes that it is important when making its compensation decisions to be informed as to the current practices of comparable public companies with which we compete for top
talent. To this end, the compensation committee reviews market data for each executive officers position, compiled by Radford as described below, including information relating to the mix and levels of compensation for executive officers in
the life sciences industry, with a focus on target total direct compensation in line with the compensation committees holistic approach to executive compensation.

2018 Peer Group. When developing a proposed list of peer companies to be used in connection with making compensation decisions for 2018, Radford re-examined our compensation philosophy and peer group criteria and companies to recommend changes to our 2017 peer group company list to reflect our growth, the increase in our revenues and market capitalization
and the consolidation in our industry. Radford recommended considering companies:



| |  | in the life sciences industry (specifically biotechnology and specialty bio/pharma companies) with commercial products on
the market;
|- |  | -------------------------------------------------------------------------------------------------------------------------------------



| |  | with revenue of approximately one-fourth (0.25x) to three times (3x) our
then-projected revenue (resulting in a range of $375 million to $5 billion in revenue);
|- |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | with market values of approximately one-fourth (0.25x) to four times (4x) our
market capitalization at the time (resulting in a range of between $2.3 billion to $36 billion in market capitalization); and
|- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | primarily located in the U.S. with a secondary focus on companies that are headquartered in Europe.
|- |  | ---------------------------------------------------------------------------------------------------

Based on these criteria, in August 2017, to form our 2018 peer group, Radford recommended, and our compensation committee approved, eliminating Actelion Ltd. and
Medivation, Inc. (which were acquired since the 2017 peer group company list was approved) from our peers and adding Bioverativ Inc. to form our 2018 peer group.

2019 Peer Group. When developing a proposed list of peer companies to be used in connection with making compensation decisions for 2019, Radford recommended
companies based on the same criteria used for the 2018 peer group, adjusted for then-current revenue and market values. Based on these criteria, in October 2018, Radford recommended, and our compensation committee approved, eliminating Bioverativ
Inc. (which was acquired since the 2018 peer group company list was approved), Shire plc (which announced its intent to be acquired in May 2018) and The Medicines Company (which fell below the then-current revenue criteria) from our peers and adding
Exelixis, Inc. (which met both the revenue and market capitalization criteria) and Nektar Therapeutics, Neurocrine Biosciences, Inc. and Sarepta Therapeutics, Inc. (which each met the market capitalization criteria) to form our 2019 peer group.

The Jazz percentile ranks shown above reflect trailing 12 months revenue and 30-day average
market capitalization for our company and the median of each peer group, measured as of the time Radford prepared its final recommendations regarding each peer group for the compensation committee.

2018 Market Data. In early 2018, Radford completed an assessment of executive compensation based on our 2018 peer group to inform the compensation
committees determinations of executive compensation for 2018. This assessment used market data that was compiled from multiple sources, including: (i) data from the Radford Global Life Sciences Survey with respect to the 2018 peer group
companies listed above, or the peer survey data; (ii) the 2018 peer group companies publicly disclosed information, or public peer data; and (iii) data from public biotechnology and pharmaceutical companies in the Radford Global Life
Sciences Survey that had revenue from $375 million to $5 billion, or the general survey data, which included survey data with respect to our selected 2018 peer group companies. The components of the market data were based on the
availability of sufficient comparative data for an executive officers position. Generally, peer survey data and public peer data are used in establishing market data reference points, and the general survey data is used when there is a lack of
peer survey data and public peer data for an executive officers position. The peer survey data, the general survey data, and the public peer data, collectively referred to in this report as market data, were reviewed by the compensation
committee, with the assistance of Radford, and used as one reference point, in addition to other factors, in setting our NEOs compensation.

Use of 2018
Market Data. The compensation committee reviews target total direct compensation, comprising both target total cash compensation and equity compensation, against the market data described above primarily to ensure that our executive compensation
program, as a whole, is positioned competitively to attract and retain the highest caliber of executive officers and that the total direct compensation opportunity for the executive officer group is aligned with our corporate objectives and
strategic needs. The compensation committee does not target a specific percentile for setting the level of compensation for the NEOs and does not otherwise use a formulaic approach to setting pay against the market data; rather, the compensation
committee reviews a range of market reference points (generally at the 25th, 50th, 60th
and 75th percentiles of the market data) for target total direct compensation including the elements of pay (base salary, target annual performance bonus and equity awards) as one factor before
making compensation determinations. The

compensation committee believes that over-reliance on benchmarking can result in compensation that is unrelated to the value delivered by our executive officers because compensation benchmarking
does not take into account company-to-company variations among actual roles with similar titles or the specific performance of the executive officers.

Factors Used in Determining Executive Compensation

Our compensation committee sets the compensation of our executive officers at levels that the compensation committee determines to be competitive and appropriate for
each NEO, using the compensation committees professional experience and judgment. The compensation committees pay decisions are not driven by a particular target level of compensation to market data, and the compensation committee does
not otherwise use a formulaic approach to setting executive pay. Instead, the compensation committee believes that executive pay decisions require consideration of multiple relevant factors, which may vary from year to year. The figure below
reflects the factors the compensation committee considers in determining and approving the amount, form and mix of pay for our NEOs.

2018 Advisory Vote on Executive Compensation and Shareholder Engagement

At our 2018 annual meeting, the shareholders approved, on an advisory basis, the compensation of the NEOs, as disclosed in the proxy statement for that meeting pursuant
to the compensation disclosure rules of the SEC. The compensation committee reviewed the final vote results for the proposal, and, given the significant level of shareholder support (92% of total votes cast with respect to the advisory proposal),
concluded that our compensation program continues to provide a competitive pay-for-performance package that effectively incentivizes the NEOs and encourages long-term
retention. Accordingly, the compensation committee and, with respect to our CEOs compensation, our board of directors, determined not to make any significant changes to our executive compensation policies or decisions as a result of the vote.
Our compensation committee and, with respect to our CEOs compensation, our board of directors, will continue to consider the outcome of our say-on-pay votes and
our shareholders views when making future compensation decisions for the NEOs.

We also engage with our shareholders when they have topics of particular
concern, which may include issues related to executive compensation. Shareholder feedback is reported to our compensation committee throughout the year. The following graphic describes our typical shareholder outreach and engagement cycle.

Key Components and Design of the Executive Compensation Program

Total Direct Compensation

Our compensation
program focuses on target total direct compensation, which consists of base salary, target bonus opportunity (which, together with base salary, we refer to as target total cash compensation), and long-term equity awards (valued based on an
approximation of grant date fair value).



LOGO

We also offer our executive officers severance benefits upon certain types of involuntary terminations in connection with a change in
control. The table below captioned Components of Total Direct Compensation provides an explanation of key features of each of the primary components of our executive compensation program and why we provide the particular
compensation component.

The compensation committee takes a holistic approach to compensation and seeks to ensure that the aggregate level of pay across all of the
pay elements is meeting the companys desired objectives for each executive officer. The compensation committee does not have any formal policies for allocating compensation among salary, performance bonus opportunity and equity grants.
Instead, the compensation committee uses its experience and business judgment to establish a total compensation program for each NEO that is a mix of current, short-term and long-term incentive compensation, and cash and non-cash compensation, which it believes appropriate to achieve the goals of our executive compensation program and our corporate goals.

Because we believe it is important to our success to pursue long-term corporate objectives, to avoid excessive risk-taking, and to preserve our cash resources, a
significant portion of the NEOs total direct compensation is comprised of at-risk compensation, consisting of performance-based bonus opportunities and long-term equity awards, which align
the executive officers incentives with the interests of our shareholders. This allocation between at-risk and fixed compensation is consistent with our pay-for-performance philosophy.

Plan, which is at-risk because the realized value is dependent upon our share price 
  Awards are discretionary and reviewed and generally granted annually, early in the year, at time of
hire or promotion or in other rare circumstances such as recognition of outstanding performance 
  Awards to executive officers are granted shortly after annual or quarterly financial results released to
public    Stock options and RSUs
generally vest over a 4-year period subject to executive officers continued service with us; stock option exercise price is set equal to fair market value on date of grant (i.e., closing price on
Nasdaq Global Select Market)    We
have executive share ownership guidelines to further support our ownership culture and align the interests of executive officers and shareholders |  |   Fosters ownership culture 
  Links compensation to long-term success
   Stock options are a key aspect of our pay-for-performance culture, by providing a return to our executive officers only if the market price of our ordinary shares appreciates over the stock option term
   RSU awards cover fewer shares than the
stock options that deliver a similar value to an executive officer, and as a result, RSU awards enable the company to minimize dilution to shareholders while reinforcing the importance of shareholder value creation
   RSU awards provide a return based on
the market price of our ordinary shares; if our share price declines, RSU awards correspondingly decline in value but still maintain value, and therefore, a mix of RSU awards and stock options aligns executive officers interests with those of
shareholders by minimizing incentive for short-term risk-taking at the expense of realizing long-term value

Other Benefits. Executive officers based in the United States are eligible to participate in all of our benefit
plans, such as the 401(k) Plan (see the section below Description of Compensation Arrangements401(k) Plan), our medical, dental, vision, short-term disability, long-term disability and group life insurance plans, in each
case generally on the same basis as other employees. Executive officers based in the United States or Ireland are eligible to participate in our Employee Stock Purchase Plan, or ESPP, generally on the same basis as other employees. We also have a
section 125 flexible benefits healthcare plan and a flexible benefits childcare plan under which employees can set aside pre-tax funds to pay for qualified healthcare expenses and qualified childcare
expenses not reimbursed by insurance. We do not currently offer pension or other retirement benefits in the United States, but do offer pension or other retirement benefits in certain other countries.

Severance Benefits upon Change in Control. Executive officers based in the United States are also eligible to participate in our Amended and Restated Executive
Change in Control and Severance Benefit Plan, or thechange in control plan, which is described below under the headings Additional Compensation InformationChange in Control Plan and Potential
Payments upon Termination or Change in ControlAmended and Restated Executive Change in Control and Severance Benefit Plan. The change in control plan provides certain severance benefits to participants, in connection with
specified involuntary termination events, including termination without cause and constructive termination, following a change in control. Certain executive officers who are not employed by our U.S. affiliates receive comparable change in control
benefits pursuant to their employment agreements. The compensation committee believes these severance benefits are important from a retention perspective to provide some level of protection to our executives who might be terminated following a
change in control and that the amounts are reasonable and maintain the competitiveness of our executive compensation and retention program. The compensation committee believes this structure serves to mitigate the distraction and loss of key
executive officers that may occur in connection with rumored or actual fundamental corporate changes. Such payments protect the interests of our shareholders by enhancing executive focus during rumored or actual change in control activity, retaining
executives despite the uncertainty that generally exists while a transaction is under consideration and encouraging the executives responsible for negotiating potential transactions to do so with independence and objectivity. We do not provide any
tax gross up payments on severance benefits.

Clawback Requirement. As a public company, if we are required to restate our financial results due to our
material noncompliance with any financial reporting requirements under the federal securities laws as a result of misconduct, our CEO and CFO may be legally required to reimburse our company for any bonus or other incentive-based or equity-based
compensation they receive in accordance with the provisions of section 304 of the Sarbanes-Oxley Act of 2002.

2018 Performance
Bonus Program

The corporate objectives and relative weightings established by the board of directors for the 2018 performance bonus program that were
communicated to the NEOs in early 2018 are described in the chart below. The total revenue objective described below included stretch goals with the opportunity to earn up to an additional 15% bonus program funding.



LOGO

Following the end of the year, after adding together the resulting bonus pool funding percentages for the quantitative and qualitative
objectives based on their relative weightings of 70% and 30%, respectively, the compensation committee approved an overall bonus pool funding percentage of 100.1% of the target bonus pool for the 2018 plan year, as further described below.

##### Table of Contents

The compensation committee did not set specific objectives for individual executive officers. Each executive officer is
responsible for contributing to the corporate objectives, individually and as part of the leadership team, with each objective deemed to be important in determining the level of the companys performance during the year. In approving individual
bonus awards, the compensation committee considers the individual contribution towards the companys achievement of the corporate objectives by each executive officer (other than our CEO). The actual bonus payments approved for each of the NEOs
for 2018 are described below under 2018 Compensation Decisions for Our Named Executive Officers.

Quantitative
Objectives

Each of the three main quantitative, or objectively measurable, objectives for 2018, with a total relative overall weighting of 70%, is described
in the table and accompanying footnotes below, including each objectives weighting, actual results and performance multipliers, as well as the total bonus pool funding percentage resulting from the level of achievement of the quantitative
objectives.

The compensation committee approved an algorithm with respect to each main quantitative objective (as well as the total revenue stretch goals discussed
below) for calculating the bonus pool funding attributable to the extent of achievement for each such objective. With respect to the total revenue objective, the compensation committee approved three related additional, or stretch, goals, each with
its own individual weighting. The compensation committee set specific threshold and maximum levels of achievement for the total revenue objective and the related stretch goals, which are described in the footnotes to the table below. For the
quantitative product development objectives, the compensation committee established various objectively measurable target goals within these objectives but did not set a threshold performance level; rather, an overall achievement of between 0% and
200%, measured against the multiple targets as described in more detail below, was determined by the compensation committee and used to calculate the applicable bonus pool funding percentage attributable to the product development objectives.

|(1) | If the specified threshold annual performance level was met (90% of target for the total revenue objective and the
adjusted net income objective), then a pre-established scaled performance multiplier (ranging from 50% to 150% for the total revenue objective and 50% to 200% for the adjusted net income objective) would be
used to calculate the applicable bonus pool funding percentage attributable to such quantitative objective. The performance multiplier would be zero if performance was below the threshold level, 50% if performance was at the threshold level, and
then scaled for performance above 50% up to the applicable maximum level. The performance multiplier was capped for performance above the specified maximum performance level (110% of target for the total revenue objective and 120% of target for the
adjusted net income objective).

$1,890.9 million was increased by approximately $7.7 million to adjust for certain budgeted revenues following the closing of the sale of our Prialt® (ziconotide) intrathecal
infusion, or Prialt, assets and reduced by approximately $0.5 million to adjust for the impact of foreign currency exchange rates that were more favorable than the budgeted rates.

|(4) | With respect to the Xyrem total bottle growth stretch goal, 3.8% annual bottle volume growth would have resulted in 3.5%
added to the total bonus pool funding percentage, and 4.8% annual bottle volume growth would have resulted in another 3.5% added to the total bonus pool funding percentage. Actual achievement of 5.5% bottle volume growth for 2018 was above the
threshold level of achievement.

|(5) | With respect to the Vyxeos U.S. sales volume stretch goal, the performance levels were set at achievement above the
budgeted U.S. sales volume. This stretch goal was inherently difficult to achieve from the outset given that we are still in the early stages of our launch of Vyxeos in a competitive and complex marketplace for AML. Exceeding the sales volume budget
by 5% would have resulted in 2.875% added to the total bonus pool funding percentage, and exceeding the sales volume budget by 10% would have resulted in another 2.875% added to the total bonus pool funding percentage. Actual Vyxeos U.S. sales
volume for 2018 was below the budgeted U.S. sales volume.

|(6) | With respect to the Vyxeos market access stretch goal, the performance goal consisted of achievement of market access for
Vyxeos in three European countries: UK, France and Germany. Achieving market access in each of those countries would result in 0.75% per country being added to the total bonus pool funding percentage, for a potential total of 2.25%. We were able to
achieve market access only in the UK in 2018, which resulted in 0.75% added to the total bonus pool funding percentage.

| |  | Sleep Therapeutic Area Clinical Activities               |  | This performance category consisted of the following goals: (i) FDA approval of Sunosi (solriamfetol) by the fourth quarter of 2018; (ii) solriamfetol MAA submission in EU by the fourth quarter of 2018;
(iii) achieving last patient out in Phase 2 trial of Sunosi for the treatment of excessive sleepiness in Parkinsons disease by the fourth quarter of 2018; (iv) supplemental NDA, or sNDA, and pediatric written request submission for Xyrem by
the second quarter of 2018; (v) achieving NDA submission readiness for JZP-507 by mid-2018; and (vi) completion of patient randomization in Phase 3 trial of JZP-258 by the fourth quarter of 2018. The compensation committee determined that we had met each of the performance goals for this category except for FDA approval of Sunosi by the end of 2018.                                  
| |  | Hematology/Oncology Therapeutic Area Clinical Activities |  | This performance category consisted of the following goals: (i) receiving regulatory approval from European Commission for Vyxeos for adults with newly-diagnosed t-AML or AML-MRC by the fourth quarter of 2018; (ii) cumulative enrollment of 200 patients in Phase 3 trial of defibrotide for prevention of veno-occlusive disease by the third quarter of 2018; (iii) first patient enrolled
in Phase 2 trial of defibrotide for prevention of acute Graft versus Host Disease by the first quarter of 2018; (iv) specific progress on a new recombinant crisantaspase program; and (v) selection of formulation for investigational new drug-,
or IND-, enabling activities for a new CombiPlex product candidate by the fourth quarter of 2018. The compensation committee determined that we had met each of these performance goals for this
category.
| |  | Molecule Strategies                                      |  | This performance category consisted of the following goals: (i) delivering updated integrated molecule strategy plans and 2018 portfolio recommendations by the fourth
quarter of 2018 and (ii) delivering a plan to generate data to inform use in specific patient subpopulations by the second quarter of 2018. The compensation committee determined that we had met each of these performance goals for this
category.                                                                                                                                                                                                                                                                                                                                                                                                                                   

With respect to the product development objectives, each of the three top priority goals  those relating to FDA
approval of Sunosi, JZP-258 Phase 3 trial patient randomization and EU regulatory approval of Vyxeos  carried a 20% weight, for a collective weight of 60%. The three high priority goals
 those relating to sNDA and pediatric written request submission for Xyrem, specific progress on a new recombinant crisantaspase program and selection of formulation for IND-enabling activities for CombiPlex  collectively carried a 20%
weight. The molecule strategy development goals collectively carried a 10% weight. All other goals carried a 10% weight.

In determining that the actual achievement
by the company was 90% for the product development objective, the compensation committee employed a holistic analysis that took into account the compensation committees assessment of the degree to which the product development objective
criteria were met as a whole against the backdrop of competing development priorities. In this regard, the compensation committee took into account the fact that the company had multiple planned milestones in 2018 and that the Xyrem sNDA submission
and regulatory approval and the solriamfetol MAA submission in particular required dedication of significant development resources

that made achieving the established performance criteria more difficult. In addition, certain of the 2018 development criteria were aggressive and set at challenging levels. Although we had
achieved 12 out of our 13 performance criteria, the compensation committee considered that the FDAs decision on approval of Sunosi, one of the three top priority goals, was postponed to 2019 through an extension of the Prescription
Drug User Fee Act date resulting from a submission we made during the course of discussions with the FDA regarding draft labeling. After considering the extent to which the performance criteria had been met as a whole against the backdrop of
competing priorities, and after factoring in the difficulty of achievement of the performance criteria that were met and that were not met, the compensation committee determined that, on balance, the achievement by the company was at the 90% level.

Qualitative Objectives

The qualitative
corporate objectives approved by the board of directors fell into two categories: (1) progress on corporate development activities, with a relative weighting of 20%, and (2) a demonstrated commitment to and progress on certain
organizational goals, with a relative weighting of 10%. Achievement of the qualitative objectives is inherently less objectively measurable than with respect to the quantitative objectives.

Corporate Development Objective.The objective relating to progress on corporate development activities consisted of identifying and implementing new
collaborations and acquisitions and expanding our development and commercial portfolio of innovative products through a range of strategic and partnering transactions with a focus on sleep, hematology/oncology and identification of additional
therapeutic area opportunities. The multiplier applied to the corporate development objective ranged from 0% to 200%, based on the compensation committees determination of the extent to which the corporate development objective was achieved
during the year. In considering the companys corporate development accomplishments in 2018, the compensation committee noted that we had identified one significant opportunity which we ultimately determined not to pursue and completed a
significant strategic partnership deal with Codiak, Inc., which closed in the first week of 2019, that we believe will allow us to potentially develop multiple new therapies as we seek to add long-term value for patients and shareholders. The
compensation committee weighed heavily our successful divestiture of our Prialt assets, our efforts to enhance our internal corporate development approval process and governance structure, our successful refinancing of our credit agreement, and our
active and thoughtful corporate development process that led to the evaluation of several other opportunities during the year. However, because we were not able to close at least one significant corporate development transaction, the compensation
committee determined that, as a whole, our achievement resulted in a multiplier of 60% and, therefore, a 12% bonus pool funding percentage for the 2018 corporate development objective.

Organizational Objective. With respect to the organizational objective, the compensation committee established three
sub-goals. Because the sub-goals are not objectively measurable, they were not assigned individual weightings. The multiplier applied to the organizational corporate
objective ranged from 0% to 200%, based on the compensation committees determination of the extent to which the aggregate organizational corporate objective, including sub-goals, were achieved, as a
whole, during the year. The organizational corporate objective sub-goals were:



| | developing, implementing and recognizing inclusive people leadership practices and behaviors across the company;
|- | ----------------------------------------------------------------------------------------------------------------



| | continuing to attract and retain talent to drive execution of initiatives in line with the companys strategy,
mission and values; and
|- | --------------------------------------------------------------------------------------------------------------------------------------



| | enhancing our differentiating capabilities and driving organizational efficiencies.
|- | -----------------------------------------------------------------------------------

In evaluating the organizational objective, the compensation committee determined that, among other things, the following organizational and operational accomplishments
were relevant: entry into innovative settlement agreements with our remaining Xyrem ANDA filers which provide additional clarity related to our Xyrem intellectual property; refinement of our global molecule team and project team structures to
enhance accountability for strategy development and execution and to achieve a more scalable, streamlined and thoughtful portfolio management process; specified hiring quality scores and voluntary turnover rates at or below certain thresholds; and
implementation of a launch framework for Vyxeos in the EU and Sunosi in the U.S. After taking into consideration both our accomplishments and challenges with respect to these sub-goals, the compensation
committee determined that as a whole, our overall achievement resulted in a multiplier of 100% and therefore, a 10% bonus pool funding percentage for the 2018 organizational objective.

2018 Compensation Decisions for Our Named Executive Officers

General Approach

In making compensation
decisions for 2018, the compensation committee considered the factors discussed in Factors Used in Determining Executive Compensation above and the compensation committees specific compensation objectives for 2018. Our
compensation committee did not use a formula or assign a particular weight to any one factor in determining each NEOs target total direct compensation. Rather, our compensation committees determination of the target total direct
compensation, mix of cash and equity and fixed and at-risk pay opportunities was a subjective, individualized decision for each NEO. The compensation committee reviewed and considered each element
of pay in the context of the overall target total direct compensation for each NEO. When the compensation committee made changes to one element of pay, those changes were made in the context of the levels of the other elements of pay, and the
resulting target total direct compensation for each NEO. As a result, the 2018 pay decisions for each NEO are presented holistically in this section.

The
compensation committee also reviewed market data with respect to target total direct compensation for similarly-situated executives of our peer companies, and also had access to market data with respect to target total cash compensation and target
equity award grants. However, as described above, the compensation committee believes that over-reliance on benchmarking can result in compensation that is unrelated to the value delivered by our executive officers because compensation benchmarking
does not take into account company-by-company variations among actual roles with similar titles or the specific performance of our executive officers.

Summary of 2018 Compensation Decisions

Target Total Cash Compensation. The compensation committee increased each NEOs base salary for 2018, and the new base salary rates were effective
February 17, 2018. There were no changes to the 2018 target performance bonuses (expressed as a percentage of base salary) for any of the NEOs because the compensation committee determined the current percentages remained at appropriate levels
and were consistent with our philosophy that the target percentages should generally vary based on each NEOs job level in order to promote internal equity for positions of similar scope and impact and to reinforce teamwork across the executive
group. Mr. Cozadds annual target performance bonus (as a percentage of salary) was set at a higher percentage than the percentages for other NEOs to reflect that he has ultimate responsibility for our companys performance.
Mr. Cozadds target bonus percentage has remained the same since 2012.

Target Equity Compensation and Impact on Target Total Direct Compensation.
In determining the appropriate size of 2018 equity award grants, at the time the compensation committee (and the board of directors, with respect to Mr. Cozadd) made its decisions, after careful consideration, the compensation committee aimed
to deliver equity awards to each executive officer of a similar value to those delivered in 2017 to balance the need to manage overall dilution to our shareholders, maintain equity opportunities competitive with the market and serve the retention
and incentive purposes of the awards. As a result of our share price decreasing slightly between when the compensation committee approved the equity awards and when the equity awards were granted pursuant to our equity incentive grant policy, as
further described below under Equity Grant Timing and Equity Plan Information, certain NEOs equity award grant date values, and resulting target total direct compensation for 2018, were modestly lower than in 2017, as shown
in the tables below.

Form and Mix of Equity Awards and Share Amount Determinations. The compensation committee intended to deliver approximately 50% of the
potential value of each NEOs equity award in the form of stock options and 50% of the potential value in the form of RSUs, in each case based on an approximation of grant date fair value, using an approximately 2.5 to 1 ratio of stock option
grants to RSUs, in order to mitigate dilution and to reflect the increased value of receiving shares at full value without the payment of an exercise price. The 50/50 value split was consistent with our historical practices for both our executive
officers and other employees and took into consideration peer practices and market data. The actual share amounts granted to each executive officer were determined by applying the companys 90-day average
share price (as of December 31, 2017) to the grant date fair value of the award, which the compensation committee and, in the case of Mr. Cozadd, the board of directors, intended to deliver (dividing such value by the average share price,
in the case of RSUs, and applying a Black-Scholes option pricing model calculation using the average share price, in the case of stock options). A 90-day average share price was used, rather than a single day
share price, in order to provide a more stabilized share value less susceptible to possible swings in the market. The exercise price of each stock option is equal to our closing share price on Nasdaq Global Select Market on the date of grant. The
compensation committee understands that this process can result in the actual reported grant date value of an award being higher or lower than the intended value approved by the compensation committee, but has considered, in consultation with
Radford, various approaches to granting equity awards, each of which have advantages and disadvantages, and determined that the



23

##### Table of Contents

process described above, which has been used historically by the compensation committee, is the most appropriate for the company at this time. The shares subject to the option awards vest over
four years, with 25% vesting on the one-year anniversary of the grant date and the remainder vesting in equal monthly installments thereafter over the remaining 36 months. The RSUs vest over four years in
equal annual installments.

On an annual basis, the compensation committee reviews market trends, including market peer use of performance-based vesting for equity
awards, which are often favored by proxy advisory firms and certain institutional investors. For 2018, the compensation committee determined that equity awards vesting over time continued to be the most appropriate incentive structure for our
executive officers to reward performance over time and achieve our retention objectives. Our time-based vesting schedules deliver retention incentives for the company over the long-term and, unlike awards that vest based on pre-determined operational or market goals, do not create incentives for inappropriate short-term risk-taking at the expense of realizing long-term value or the potential incentive for unethical conduct. In
addition, we deliver a meaningful portion of compensation in the form of annual incentive compensation that is directly tied to, and incentivizes our executives to work towards, achievement of our key corporate goals. The key purposes served by
time-vesting options and RSUs for 2018 are further discussed above in the chart captioned Components of Total Direct Compensation.

Individual NEO Compensation Decisions

Below are summaries, for each NEO individually, of the compensation committees decisions about 2018 target
total direct compensation and the changes from each NEOs 2017 target total direct compensation. As described above, when making the 2018 compensation decisions, the compensation committee focused primarily on the target total direct
compensation for each NEO while considering the factors set forth in the section titled Factors Used in Determining Executive Compensation and the compensation committees specific compensation objectives for 2018. The
footnotes to the tables also include the actual performance bonus paid to each of the NEOs for 2018 and how that actual bonus compared to each NEOs target bonus.

|(1) | Reflects where the 2018 target total direct compensation (annual base salary, target performance bonus and the target
equity compensation value approved by the compensation committee) fell within the market data at the time reviewed and approved by the compensation committee. The target equity compensation delivered (as presented in the chart) reflects the fair
value of the awards as of the grant date, in accordance with FASB Accounting Standards Codification Topic 718, CompensationStock Compensation, or ASC 718, which was modestly lower than the target equity compensation value approved by
the compensation committee as a result of the timing of the grant and a slight decrease in our share price as of the grant date, as described above.

|(3) | Target amounts are as reported in the Grants of Plan-Based Awards Table for 2017 and 2018, respectively, and reflect the
target percentage of base salary earned for each fiscal year. The 2018 amount reflects a target performance bonus of 100% of base salary earned, unchanged from the target performance bonus percentage for 2017. The actual 2018 performance bonus paid
was $980,300, reflecting 100.1% of the target performance bonus, based entirely on the overall 2018 bonus pool funding percentage of 100.1%. The compensation committee (with approval from the board of directors) determined that the overall 2018
bonus pool funding percentage of 100.1% was applicable to Mr. Cozadd, because, as CEO, Mr. Cozadd is responsible for the company meeting all of its objectives.

|(4) | Target equity compensation dollar amounts represent the grant date fair value of each stock option and RSU award, as
applicable, and have been calculated in accordance with ASC 718 as reported in the Grants of Plan-Based Awards Table for 2017 and 2018, respectively. See the Grants of Plan-Based Awards Table for the number of shares subject to each award.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(5) | The compensation committee and board of directors designed Mr. Cozadds target total direct compensation to be
competitive compared to the market data, appropriate from an internal equity perspective and more heavily weighted towards equity compensation, in line with our
pay-for-performance philosophy. The compensation committee believed it was appropriate to provide a modest increase to his base salary and an increase in the value of
equity awards granted to Mr. Cozadd in 2018 in recognition of his individual performance, the performance of the company under his leadership and an assessment of internal equity and to remain in line with general market increases. As described
above, Mr. Cozadds target bonus percentage remained the same as in 2017, and while the increase in his base salary resulted in a higher target performance bonus opportunity, Mr. Cozadds target total direct compensation for 2018
did not exceed the median of the market data.

|(2) | Reflects where the 2018 target total direct compensation (annual base salary, target performance bonus and the target
equity compensation value approved by the compensation committee) fell within the market data for a newly hired President and COO at the time reviewed and approved by the compensation committee. The target equity compensation delivered (as presented

to such achievement. Specifically, the compensation committee considered that Mr. Swisher oversaw a large and complex function, and, with the vacancy in the companys role of head of research and development for the majority of the year,
the compensation committee took into account Mr. Swishers scope of responsibility and the criticality of his role.

applicable, and have been calculated in accordance with ASC 718 as reported in the Grants of Plan-Based Awards Table for 2018. See the Grants of Plan-Based Awards Table for the number of shares subject to each award. As a result of the timing of
Mr. Swishers new-hire equity awards, he was not eligible to receive regular annual equity awards during 2018.
|--- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(7) | The compensation committee designed Mr. Swishers target total direct compensation to be competitive compared
to the market data, appropriate from an internal equity perspective and more heavily weighted towards equity compensation, in line with our pay-for-performance
philosophy. In determining his compensation package, the compensation committee considered the companys executive compensation program and received advice from Radford to design a competitive, market-based compensation package appropriate
for a senior executive with Mr. Swishers skills and experience.

|--- | -----------------------------------------------------------



|(3) | Target amounts are as reported in the Grants of Plan-Based Awards Table for 2017 and 2018, respectively, and reflect the
target percentage of base salary earned for each fiscal year. The 2018 amount reflects a target performance bonus of 55% of base salary earned, unchanged from the target performance bonus percentage for 2017. The actual 2018 performance bonus paid
was $365,000, reflecting 115% of target performance bonus, based on the overall 2018 bonus pool funding percentage of 100.1% and Mr. Youngs significant individual contributions to such achievement. Specifically, the compensation committee
considered Mr. Youngs overall leadership across the company, including our finance organization, investor relations, facilities and information technology, his performance with respect to the execution of corporate development and capital
financing priorities in 2018, particularly with respect to the refinancing of our credit agreement and in light of the vacancy in the companys role of head of corporate development for a majority of the year, and his criticality to the
companys business as a whole.

applicable, and have been calculated in accordance with ASC 718 as reported in the Grants of Plan-Based Awards Table for 2017 and 2018, respectively. See the Grants of Plan-Based Awards Table for the number of shares subject to each award.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(5) | The compensation committee designed Mr. Youngs target total direct compensation to be competitive compared to
the market data, appropriate from an internal equity perspective and more heavily weighted towards equity compensation, in line with our pay-for-performance philosophy.
Consistent with the approach for 2018 equity award grants described above, the compensation committee generally aimed to deliver equity awards to the executive vice presidents of a similar grant date value to those delivered to executive vice
presidents in 2017. Mr. Youngs target equity award grant date value and resulting target total direct compensation for 2018 were comparable to 2017. The compensation committee determined it was appropriate to increase
Mr. Youngs base salary from an internal pay equity perspective, in an amount that reflects his knowledge and expertise in the role and the criticality of Mr. Youngs role as our CFO and to bring his base salary closer to other
NEOs who contribute similarly. In addition, the compensation committee considered the retention value of his compensation given Mr. Youngs criticality to the companys business development strategy and the breadth of his impact on
the business. As described above, Mr. Youngs target bonus percentage remained the same as in 2017, and the increase in his base salary resulted in the higher target performance bonus opportunity shown above.

value of the awards as of the grant date, in accordance with ASC 718, which was modestly lower than the target equity compensation value approved by the compensation committee as a result of the timing of the grant and a slight decrease in our share

target percentage of base salary earned for each fiscal year. The 2018 amount reflects a target performance bonus of 55% of base salary earned, unchanged from the target performance bonus percentage for 2017. The actual 2018 performance bonus paid
was $400,000, reflecting 126.0% of target performance bonus, based on the overall 2017 bonus pool funding percentage of 100.1% and Ms. Hoopers significant individual contributions to such achievement. Specifically, the compensation
committee considered Ms. Hoopers leadership in settling the companys litigation with the last remaining Xyrem ANDA filers, her oversight of complex strategic matters relating to Xyrem and our other products and her performance with
respect to executing financing priorities in 2018.

|(5) | The compensation committee designed Ms. Hoopers target total direct compensation to be competitive compared to
the market data, appropriate from an internal equity perspective and more heavily weighted towards equity compensation, in line with our pay-for-performance philosophy.
Consistent with the approach for 2018 equity award grants described above, the compensation committee generally aimed to deliver equity awards to the executive vice presidents of a similar grant date value to those delivered to executive vice
presidents in 2017. Ms. Hoopers target equity award grant date value and resulting target total direct compensation for 2018 were comparable to 2017. Ms. Hoopers resulting target total direct compensation fell between the 50th and 60th percentile of the market data, which the compensation committee determined was appropriate because of Ms. Hoopers experience,
her oversight of multiple functions including legal, compliance, corporate affairs and government relations, and her sustained contribution and overall criticality to our business. The compensation committee determined it was appropriate to
increase Ms. Hoopers base salary because of her contributions to achieving strategic initiatives in line with corporate objectives. As described above, Ms. Hoopers target bonus percentage remained the same as in 2017, and
the increase in her base salary resulted in the higher target performance bonus opportunity shown above. In January 2019, Ms. Hooper notified us of her decision to resign from her position as Executive Vice President and GC, effective as of
March 1, 2019. Ms. Hooper continues to be employed by us as a part-time, non-executive employee during a transition period.

Additional Compensation Information

Ownership Guidelines for Executive Officers

We maintain share ownership guidelines for our CEO and certain other employees who serve on our executive committee, including our NEOs. Under the guidelines, which were
amended in May 2018, these individuals are expected to own a number of the companys ordinary shares with a value equal to six times base salary (increased from three times base salary) for the companys Chief Executive Officer, two times
base salary (increased from one times base salary) for each other member of the companys executive committee who is an officer for purposes of Section 16 of the Exchange Act, and one times base salary for each other member of the
companys executive committee. The guidelines provide that the officers are expected to establish the minimum ownership levels within five years of first becoming subject to the guidelines (and, with respect to the increased amounts established
by the amended guidelines, by the last day of 2021 for officers who were subject to the guidelines as of January 1, 2018). Each of our continuing NEOs was in compliance with the guidelines as of March 31, 2019, except as noted below.

|(1) | Actual ownership calculated based on (a) value of shares owned as of March 31, 2019, using the closing price of
the companys ordinary shares on March 29, 2019 of $142.95, divided by (b) 2019 base salary. Under the guidelines as amended in May 2018, once an officer has reached his or her compliance deadline, such officers share ownership will
be assessed annually at the end of each fiscal year using the average closing price of the companys ordinary shares over the 90-day period ending on the last day of the companys
immediately preceding fiscal year.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(2) | Mr. Swisher was appointed our President and COO as of January 3, 2018 and, accordingly, has five years from his
appointment, or until 2023, to comply with the guidelines.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Shares that count toward satisfaction of these guidelines include: shares owned
outright by the individual (including RSUs that have vested but not yet settled, net of taxes); shares retained after an option exercise or issuance under another type of equity award granted under the companys equity incentive plans; shares
retained after purchase under the ESPP; and shares held in trust for the benefit of the individual. The compensation committee has discretion to develop an alternative individual guideline or an alternative method of complying with the applicable
individual guideline for an individual covered by the guidelines if compliance would place a significant hardship on such individual.

Change in Control Plan

Our compensation
committee periodically reviews the terms of our change in control plan, including its double-trigger structure and benefits, against market data to ensure that the benefits we offer remain appropriate.

The compensation committee last made refinements to the program in 2016 to provide greater clarity, reflect market practice and improvements for both the executives and
our company and updates in applicable law since the plan was originally adopted in 2007. Only our executive officers who are employees of our U.S. affiliates are eligible to participate in the change in control plan, which includes all of our NEOs.
Certain executive officers who are not employed by our U.S. affiliates receive comparable change in control benefits pursuant to their employment agreements. The compensation committee believes that the change in control benefits we provide are
representative of market practice, both in terms of design and cost, and are sufficient to retain our current executive team and to recruit talented executive officers in the future. The terms of the change in control plan are described below under
the heading Potential Payments upon Termination or Change in ControlAmended and Restated Executive Change in Control and Severance Benefit Plan.

Equity Grant Timing and Equity Plan Information

Our equity incentive grant policy, which was initially approved by our board of directors after the Azur Merger and amended and restated most recently in November 2017,
provides that all equity grants that are approved for executive officers will be granted on the second trading day following the filing date of our next quarterly or annual report filed under the Exchange Act that occurs after the date on which such
grants are approved by our board of directors or compensation committee, as applicable. Accordingly, our equity incentive grant policy requires that grants to our executive officers, if



30



---

##### Table of Contents

any, be made shortly after we have released information about our financial performance to the public for the applicable annual or quarterly period, so that the market will have an opportunity to
absorb the financial and other information included in our annual and periodic reports before such grants are awarded. As a result, the timing of equity awards is not coordinated in a manner that intentionally benefits our executive officers;
rather, the policy is designed with the objective that the market price of our ordinary shares at the time of grant can generally be expected to reflect our then-current results and prospects.

We currently grant equity awards to the NEOs, including stock options and RSUs, under the 2011 Equity Incentive Plan, or the 2011 Plan. The 2011 Plan was adopted by Jazz
Pharmaceuticals, Inc.s board of directors and approved by Jazz Pharmaceuticals, Inc.s stockholders in connection with their approval of the Azur Merger in December 2011 and was assumed by us upon the completion of the Azur Merger. Before
the 2011 Plan was adopted, we granted stock options under our 2007 Equity Incentive Plan, or the 2007 Plan, which was adopted by Jazz Pharmaceuticals, Inc.s board of directors and approved by Jazz Pharmaceuticals, Inc.s stockholders in
connection with Jazz Pharmaceuticals, Inc.s initial public offering. Awards granted under the 2007 Plan continue to be governed by the terms of the 2007 Plan, but subsequent equity awards have been, and continue to be, awarded under the 2011
Plan. The 2011 Plan affords the compensation committee the flexibility to utilize a broad array of equity incentives and performance cash incentives in order to secure and retain the services of employees of our company and its subsidiaries and to
provide long-term incentives that align the interests of employees with the interests of our shareholders.

Additional long-term equity incentives are provided
through the ESPP, which we assumed upon the completion of the Azur Merger. Pursuant to the ESPP, all eligible employees, including the NEOs, may allocate up to 15% of their base salary to purchase our stock at a 15% discount to the market price,
subject to specified limits.

Accounting and Tax Considerations

Under ASC 718, the company is required to estimate and record an expense for each award of equity compensation (including stock options and RSUs) over the vesting period
of the award. We record share-based compensation expense on an ongoing basis according to ASC 718. The compensation committee has considered, and may in the future consider, the grant of performance-based or other types of stock awards to executive
officers in lieu of or in addition to stock option and time-based RSU grants in light of the accounting impact of ASC 718 and other considerations.

Under
Section 162(m) of the Internal Revenue Code, or Section 162(m), compensation paid to any publicly held corporations covered employees that exceeds $1 million per taxable year for any covered employee is generally non-deductible for tax purposes.

Prior to the enactment of the U.S. Tax Act, Section 162(m) provided a performance-based
compensation exception, pursuant to which the deduction limit under Section 162(m) did not apply to any compensation that qualified as performance-based compensation under Section 162(m). Pursuant to the U.S. Tax Act, the
performance-based compensation exception under Section 162(m) was repealed with respect to taxable years beginning after December 31, 2017, except that certain transition relief is provided for compensation paid pursuant to a written
binding contract which was in effect on November 2, 2017 and which is not modified in any material respect on or after such date.

Compensation paid to each of
the companys covered employees in excess of $1 million per taxable year generally will not be deductible unless it qualifies for the performance-based compensation exception under Section 162(m) pursuant to the transition
relief described above. Because of certain ambiguities and uncertainties as to the application and interpretation of Section 162(m), as well as other factors beyond the control of the compensation committee, no assurance can be given that any
compensation paid by the company will be eligible for such transition relief and be deductible by the company in the future. Although the compensation committee will continue to consider tax implications as one factor in determining executive
compensation, the compensation committee also looks at other factors in making its decisions and retains the flexibility to provide compensation for the companys named executive officers in a manner consistent with the goals of the
companys executive compensation program and the best interests of the company and its stockholders, which may include providing for compensation that is not deductible by the company due to the deduction limit under Section 162(m). The
compensation committee also retains the flexibility to modify compensation that was initially intended to be exempt from the deduction limit under Section 162(m) if it determines that such modifications are consistent with the companys
business needs.

Risk Assessment Concerning Compensation Practices and Policies

The compensation committee annually reviews the companys compensation policies and practices to assess whether they encourage employees to take inappropriate
risks. After reviewing each of the companys compensation plans, and the checks and balances built into, and oversight of, each plan, in February 2019, the compensation committee determined that any risks arising from our compensation policies
and practices for our employees are not reasonably likely to have a material adverse effect on our company as a whole. In addition, the compensation committee believes that



31

##### Table of Contents

the mix and design of the elements of executive compensation do not encourage management to assume excessive risks, and significant compensation decisions, as well as decisions concerning the
compensation of the companys executive officers, include subjective considerations by the compensation committee or the board of directors, which restrain the influence of formulae or objective factors on excessive risk-taking. Finally, the
mix of short-term compensation (in the form of salary and annual bonus, if any), and long-term compensation (in the form of stock options and RSUs) also prevents undue focus on short-term results and helps align the interests of the companys
executive officers with the interests of our shareholders.

Reconciliations of Non-GAAP
Financial Measures

To supplement our financial results presented in accordance with U.S. generally accepted accounting principles (GAAP), we use certain non-GAAP (also referred to as non-GAAP adjusted) financial measures in this Compensation Discussion and Analysis. In particular, we present
non-GAAP adjusted net income (and the related per share measures), which exclude certain items from reported GAAP net income and reported GAAP net income attributable to Jazz Pharmaceuticals plc (and the
related per share measures), as applicable, as detailed in the reconciliation table that follows, adjust for the income tax effect of the non-GAAP adjustments and, for the 2017 and 2018 periods, adjust for the
U.S. Tax Act benefit, and finally, for the 2015 period, adjust for the amount attributable to non-controlling interests.

We
believe that each of these non-GAAP financial measures provides useful supplementary information to, and facilitates additional analysis by, investors and analysts. In particular, we believe that each of these
non-GAAP financial measures, when considered together with our financial information prepared in accordance with GAAP, can enhance investors and analysts ability to meaningfully compare our results
from period to period, and to identify operating trends in our business. In addition, these non-GAAP financial measures are regularly used by investors and analysts to model and track our financial
performance. Our management also regularly uses these non-GAAP financial measures internally to understand, manage and evaluate our business and to make operating decisions, and compensation of our executives
is based in part on these non-GAAP financial measures. Because these non-GAAP financial measures are important internal measurements for our management, we also believe
that these non-GAAP financial measures are useful to investors and analysts since these measures allow for greater transparency with respect to key financial metrics we use in assessing our own operating
performance and making operating decisions.

These non-GAAP financial measures are not meant to be considered in isolation or
as a substitute for comparable GAAP measures; should be read in conjunction with our consolidated financial statements prepared in accordance with GAAP; have no standardized meaning prescribed by GAAP; and are not prepared under any comprehensive
set of accounting rules or principles. In addition, from time to time in the future, there may be other items that we may exclude for purposes of our non-GAAP financial measures, and we have ceased, and may in
the future cease, to exclude items that we have historically excluded for purposes of our non-GAAP financial measures. Likewise, we may determine to modify the nature of our adjustments to arrive at our non-GAAP financial measures. Because of the non-standardized definitions of non-GAAP financial measures, the non-GAAP financial measures as used by us in this Compensation Discussion and Analysis have limits in their usefulness to investors and may be calculated differently from, and therefore may not be directly
comparable to, similarly titled measures used by other companies.

|(1) | This column sets forth the target bonus amount for each NEO for the year ended December 31, 2018 under the
performance bonus plan. There are no thresholds or maximum bonus amounts for each individual officer established under the performance bonus plan. Target bonuses were set as a percentage of each NEOs base salary earned for the fiscal year
ended December 31, 2018 and were 100% for Mr. Cozadd and 55% for each of Messrs. Swisher, Young and Miller and Ms. Hooper. The dollar value of the actual bonus award earned for the year ended December 31, 2018 for each NEO is set
forth in the Summary Compensation Table above. As such, the amounts set forth in this column do not represent either additional or actual compensation earned by the NEOs for the year ended December 31, 2018. For a description of the performance
bonus plan, see Compensation Discussion and Analysis2018 Performance Bonus Program above.

|(2) | Annual stock options and RSU awards were granted under the 2011 Plan. In January 2018, Mr. Swisher joined the company
as President and COO, and received a new hire grant of stock option and RSU awards, which were granted under the 2011 Plan. Each of the annual stock option awards listed in the table above vested as to 25% of the ordinary shares underlying the stock
options upon the one year anniversary of the applicable grant date and vest as to the remainder of the shares in 36 equal monthly installments thereafter. Each of the annual RSU awards vest in four equal annual installments on the anniversary of the
vesting commencement date of March 5, 2018. Mr. Swishers initial stock option award vested as to 25% of the ordinary shares underlying the stock options upon the one year anniversary of his hire date of January 3, 2018 and vests
as to the remainder of the shares in 36 equal monthly installments thereafter. His initial RSU award vests in four equal annual installments on the anniversary of his hire date of January 3, 2018. As a general matter, the vested portion of
stock options granted to the NEOs will expire three months after each NEOs last day of service, subject to extension upon certain termination situations, such as death or disability, and RSUs will cease vesting upon each NEOs last day of
service. Stock option and RSU awards are subject to potential vesting acceleration as described below under the headings Description of Compensation ArrangementsEquity Compensation Arrangements2011 Equity Incentive
Plan and Potential Payments upon Termination or Change in ControlAmended and Restated Executive Change in Control Plan and Severance Benefit Plan below. See also Description of Compensation
ArrangementsEquity Compensation Arrangements2011 Equity Incentive Plan below for a general description of the material terms of the 2011 Plan.

|(3) | Stock options were granted with an exercise price equal to 100% of the fair market value on the date of grant which was
$140.67 per share for the March 1, 2018 annual grants.
|--- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(4) | The dollar amounts in this column represent the grant date fair value of each stock option and RSU award, as applicable,
granted to the NEOs in 2018. These amounts have been calculated in accordance with ASC 718. The grant date fair value of each stock option is calculated using the Black-Scholes option-pricing model and excluding the effect of estimated forfeitures.
Assumptions used in the calculation of these amounts are included in the notes to our audited consolidated financial statements included in the companys 2018 Annual Report on Form 10-K. The grant date
fair value of each RSU award is measured based on the closing price of our ordinary shares on the date of grant.

Description of Compensation Arrangements

Executive Employment and Severance Agreements

We do not have
employment agreements currently in effect with any of our NEOs. Like other employees, executive officers are eligible for annual salary increases, participation in the performance bonus plan and discretionary equity grants. We have employment
agreements in effect with certain employees based outside of the United States.

From time to time, we have provided an offer letter in connection with the
commencement of employment of an executive officer based in the United States, which describes such executive officers initial terms of employment. For example, in November 2017, we provided an offer letter to Mr. Swisher that included
his initial base salary and a hiring bonus of $125,000 payable in connection with commencement of employment. The employment of Mr. Swisher, as is the case for all of our employees based in the United States, is
at-will and not governed by the terms of his offer letter. We do not have agreements currently in effect with any of our NEOs entitling such individuals to severance benefits (other than in connection with a
change in control pursuant to our change in control plan described below).

Amended and Restated Executive Change in Control and Severance Benefit Plan

Each of the NEOs is a participant in the change in control plan, a description of which is included below under the heading Potential Payments upon
Termination or Change in ControlAmended and Restated Executive Change in Control and Severance Benefit Plan.

Equity Compensation Arrangements

Since the Azur Merger, we have granted stock options and RSU awards to employees, including the NEOs, under the 2011 Plan. From the initial public offering
of Jazz Pharmaceuticals, Inc. until the Azur Merger, we granted stock options to our employees, including some of the NEOs, under the 2007 Plan. For more information on our current equity compensation program and decisions regarding the grants of
equity awards in 2018 for our NEOs, see Compensation Discussion and Analysis2018 Compensation Decisions for Our Named Executive Officers. The following is a brief summary of the material terms of each of our equity
compensation plans.

2011 Equity Incentive Plan

In connection with the
Azur Merger, Jazz Pharmaceuticals, Inc.s board of directors adopted the 2011 Plan in October 2011, and its stockholders approved the 2011 Plan at the special meeting of the stockholders held in December 2011. The 2011 Plan became effective
immediately before the consummation of the Azur Merger and was assumed and adopted by us upon the consummation of the Azur Merger and most recently amended and restated by the board of directors in November 2016. The following is a brief summary of
the material terms of the 2011 Plan, as amended and restated.

Administration. The board of directors has delegated its authority to administer
the 2011 Plan to the compensation committee. Subject to the terms of the 2011 Plan, the board of directors or a committee authorized by the board determines recipients, dates of grant, the numbers and types of stock awards to be granted, and the
terms and conditions of the stock awards, including the period of their exercisability and vesting. The compensation committee has the authority to delegate its administrative powers under the 2011 Plan to a subcommittee consisting of members of the
compensation committee and may, at any time, revest in itself some or all of the power previously delegated to the subcommittee. Our board of directors may also delegate to one or more of our officers the authority to designate employees who are not
officers to be recipients of certain stock awards and the number of shares subject to such stock awards, provided that our board of directors must specify the total number of shares that may be subject to the stock awards granted by such officer(s)
and such officer(s) may not grant a stock award to himself or herself.

Types of Awards. The 2011 Plan provides for the grant of incentive stock
options, nonstatutory stock options, stock appreciation rights, restricted stock awards, RSU awards, other stock awards, and performance awards that may be settled in cash, shares, or other property, which may be granted to employees, including
officers.

Corporate Transactions. In the event of certain significant corporate transactions (as defined in the
2011 Plan and described below), our board of directors will have the discretion to take one or more of the following actions with respect to outstanding stock awards (contingent upon the closing or completion of such corporate transaction), unless
otherwise provided in the stock award agreement or other written agreement with the participant or unless otherwise provided by our board of directors at the time of grant:



| |  | arrange for assumption, continuation, or substitution of a stock award by a surviving or acquiring corporation (or its
parent company);
|- |  | ---------------------------------------------------------------------------------------------------------------------------------------



| |  | arrange for the assignment of any reacquisition or repurchase rights applicable to any shares issued pursuant to a stock
award to the surviving or acquiring corporation (or its parent company);
|- |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | accelerate the vesting, in whole or in part, and exercisability of a stock award and provide for its termination if it is
not exercised at or prior to the corporate transaction;
|- |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | arrange for the lapse of any reacquisition or repurchase rights applicable to any shares issued pursuant to a stock award;
|- |  | --------------------------------------------------------------------------------------------------------------------------



| |  | cancel or arrange for the cancellation of a stock award, to the extent not vested or exercised prior to the effective time
of the corporate transaction, in exchange for such cash consideration, if any, as the board of directors may consider appropriate; or
|- |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | make a payment equal to the excess, if any, of (a) the value of the property that the participant would have received
upon the exercise of the stock award over (b) any exercise price payable in connection with such exercise.
|- |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Our board of directors need not
take the same action for each stock award or with regard to all participants.

For purposes of the 2011 Plan, a corporate transaction generally means
(i) a sale or disposition of all or substantially all our assets or a sale or disposition of at least 90% of our outstanding securities; (ii) a merger, consolidation or similar transaction after which we are not the surviving corporation;
or (iii) a merger, consolidation or similar transaction after which we are the surviving corporation but our ordinary shares are converted or exchanged into other property.

Change in Control. The board of directors has the discretion to provide additional acceleration of vesting and exercisability upon or after a change
in control (as defined in the 2011 Plan and described below) as may be provided in a stock award agreement or any other written agreement between us or any of our affiliates and a participant. The forms of stock option agreement and RSU award
agreement adopted by the board of directors under the 2011 Plan provide that in the event a participants service relationship with us or a successor entity is terminated due to an involuntary termination without cause (as defined in the stock
award agreement and as described below) within 12 months following, or one month prior to, the effective date of a change in control, the vesting (and in the case of stock options, exercisability) of the stock award will accelerate in full.

For purposes of the 2011 Plan and the forms of stock option agreement and RSU award agreement issued thereunder, a change in control generally means
(i) a person or group acquires ownership of more than 30% of the combined voting power of our outstanding securities (other than directly from our company); (ii) certain compromises or arrangements sanctioned by the Irish courts, certain
schemes, contracts or offers that have become binding on all of our shareholders, certain takeover bids, certain offers or reverse takeover transactions or a reorganization, merger, statutory share exchange, consolidation or similar transaction
involving us, and (A) after which our shareholders do not own more than 50% of the combined voting power of the surviving entity or its parent in substantially the same proportion as their ownership of our outstanding voting securities
immediately before the transaction, (B) a person or group acquires ownership of more than 30% of the combined voting power of the surviving entity or its parent, or (C) at least a majority of the members of the board of directors of the
parent (or the surviving entity, if there is no parent) following such transaction are not incumbent board members (as defined in (v) below) at the time our board of directors approves the transaction; (iii) our shareholders or our board
of directors approves a complete dissolution or liquidation of our company, or a complete dissolution or liquidation of our company otherwise occurs (except for a liquidation into a parent company); (iv) a sale, lease, exclusive license or
other disposition of all or substantially all of our assets, other than to certain entities; or (v) individuals who were members of our board of directors on the date of adoption of the 2011 Plan (or members of our board of directors approved
or recommended by a majority vote of such members still in office), referred to as incumbent board members, cease to constitute at least a majority of our board of directors.

An involuntary termination without cause generally means that a participants service relationship with us is terminated for any reason other than for
the following reasons (and not upon a participants death or disability): (i) participants commission of any felony or crime involving fraud, dishonesty or moral turpitude under the laws of the United States or any state thereof
(with respect to Irish participants, the participants conviction for any criminal offense (other than an offense under any road traffic legislation in Ireland, the United Kingdom or elsewhere for which a fine or
non-custodial penalty is imposed) or any offense under any regulation or legislation relating to insider dealing, fraud or dishonesty); (ii) participants attempted commission of or participation in
a fraud or act of dishonesty against us; (iii) participants intentional, material violation of any contract or agreement with us or of any statutory duty owed to us; (iv) participants unauthorized use or disclosure of our
confidential information or trade secrets; or (v) participants gross misconduct.

2007 Equity Incentive Plan

The
2007 Plan, which was initially adopted by the Jazz Pharmaceuticals, Inc. board of directors and approved by the Jazz Pharmaceuticals, Inc. stockholders in connection with its initial public offering, was continued and assumed by us upon consummation
of the Azur Merger. The 2007 Plan expired in April 2017, and accordingly, no new grants can be awarded under the 2007 Plan. The following is a brief summary of the material terms of the 2007 Plan.

Administration. The board of directors delegated its authority to administer the 2007 Plan to the compensation committee. Subject to the terms of the
2007 Plan, the board of directors or a committee authorized by the board determined recipients, dates of grant, the numbers and types of stock awards to be granted, and the terms and conditions of the stock awards, including the period of their
exercisability and vesting.

Types of Awards. The 2007 Plan provided for the grant of incentive stock options, nonstatutory stock options,
restricted stock awards, RSU awards, stock appreciation rights, performance stock awards and other forms of equity compensation, which may be granted to employees, including officers, non-employee directors,
and consultants. Incentive stock options were granted only to employees, including executive officers. Since the Azur Merger, all of the new grants under the 2007 Plan were granted to non-employee directors,
vest ratably over service periods of one to three years and expire no more than 10 years after the date of grant.

Corporate
Transactions. Pursuant to the 2007 Plan, in the event of a corporate transaction (as defined in the 2007 Plan and described below), the board of directors will have the discretion to take one or more of the following actions with
respect to outstanding stock awards (contingent upon the closing or completion of such corporate transaction), unless otherwise provided in the stock award agreement or other written agreement with the participant or unless otherwise provided by our
board of directors at the time of grant:



| |  | arrange for assumption, continuation, or substitution of a stock award by a surviving or acquiring corporation (or its
parent company);
|- |  | ---------------------------------------------------------------------------------------------------------------------------------------



| |  | arrange for the assignment of any reacquisition or repurchase rights applicable to any shares issued pursuant to a stock
award to the surviving or acquiring corporation (or its parent company);
|- |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | accelerate the vesting and exercisability of a stock award and provide for its termination if it is not exercised at or
prior to the corporate transaction;
|- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | arrange for the lapse of any reacquisition or repurchase rights applicable to any shares issued pursuant to a stock award;
|- |  | --------------------------------------------------------------------------------------------------------------------------



| |  | cancel or arrange for the cancellation of a stock award, to the extent not vested or exercised prior to the effective time
of the corporate transaction, in exchange for such cash consideration as the board of directors may consider appropriate; or
|- |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | make a payment equal to the excess, if any, of (a) the value of the property that the participant would have received
upon the exercise of the stock award over (b) any exercise price payable in connection with such exercise.
|- |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The board of directors need not
take the same action for each stock award or with respect to all participants. For purposes of the 2007 Plan, a corporate transaction generally means (i) a sale or disposition of all or substantially all our assets or a sale or
disposition of at least 90% of our outstanding securities; (ii) a merger, consolidation or similar transaction after which we are not the surviving corporation; or (iii) a merger, consolidation or similar transaction after which we are the
surviving corporation but our ordinary shares are converted or exchanged into other property.

Change in Control. The board of directors has the
discretion to provide additional acceleration of vesting and exercisability upon or after a change in control (as defined in the 2007 Plan and described below) as may be provided in a stock award agreement or any other written agreement between us
or any of our affiliates and a participant. The forms of stock option agreement and RSU award agreement adopted by the board of directors under the 2007 Plan provide that in the event a participants service relationship with us or a successor
entity is terminated due to an involuntary termination without cause (as defined in the stock award agreement and as described below) within 12 months following, or one month prior to, the effective date of a change in control, the vesting (and in
the case of stock options, exercisability) of the stock award will accelerate in full. For purposes of the 2007 Plan and the forms of stock option agreement and RSU award agreement issued thereunder, a change in control generally means
(i) a person or group acquires ownership of more than 50% of the combined voting power of our outstanding securities (other than in connection with a financing or a repurchase program); (ii) a merger, consolidation or similar transaction
involving us, after which our shareholders do not own more than 50% of the combined voting power of the surviving entity or its parent in substantially the same proportion as their ownership of our outstanding voting securities immediately before
the transaction; (iii) our shareholders or our board of directors approves a complete dissolution or liquidation of our company, or a complete dissolution or liquidation

of our company otherwise occurs (except for a liquidation into a parent company); (iv) a sale, lease, exclusive license or other disposition of all or substantially all of our assets, other than
to certain entities; or (v) individuals who are members of our board of directors on the date of adoption of the 2007 Plan (or members of our board of directors approved or recommended by a majority vote of such members still in office) cease
to constitute at least a majority of our board of directors.

The term involuntary termination without cause has a similar meaning as under the 2011
Plan, as described above.

2007 Employee Stock Purchase Plan

Additional
long-term equity incentives are provided through the ESPP, which was amended and restated by Jazz Pharmaceuticals, Inc.s board of directors in October 2011 and approved by its stockholders in December 2011, to be effective immediately prior to
the Azur Merger, and, in October 2012, amended and restated by our compensation committee. The ESPP was assumed by us upon the consummation of the Azur Merger. The ESPP is intended to qualify as an employee stock purchase plan within the
meaning of section 423 of the Internal Revenue Code, or the Code. Under the ESPP, all of our regular employees and employees of any of our parent or subsidiary companies designated by the board of directors as eligible to participate may
participate and may contribute, normally through payroll deductions, up to 15% of their earnings up to a total of $15,000 per purchase period for the purchase of our ordinary shares under the ESPP. The ESPP is currently offered to our regular
employees in Ireland, Canada and the United States, including the NEOs. The ESPP is implemented through a series of offerings of purchase rights to eligible employees. Under the ESPP, we may specify offerings with a duration of not more than 27
months, and may specify shorter purchase periods within each offering. Each offering will have one or more purchase dates on which our ordinary shares will be purchased for employees participating in the offering. Unless otherwise determined by the
board of directors, ordinary shares are purchased for accounts of employees participating in the ESPP at a price per share equal to the lower of (a) 85% of the fair market value of an ordinary share on the first date of an offering or
(b) 85% of the fair market value of an ordinary share on the date of purchase.

Performance Bonus Plan

We maintain a performance bonus plan to reward executive officers and other employees for successful achievement of company-wide performance objectives and individual
contributions toward those objectives on an annual basis. More information regarding the performance bonus plan is provided above under the headings Compensation Discussion and Analysis2018 Performance Bonus Program and
Compensation Discussion and Analysis2018 Compensation Decisions for Our Named Executive Officers.

401(k) Plan

Our employees based in the United States are eligible to participate in the 401(k) Plan. The 401(k) Plan is intended to qualify as a
tax-qualified plan under section 401 of the Code. Employee contributions are held and invested by the 401(k) Plans trustee. The 401(k) Plan provides that each participant may contribute a portion of
his or her pre-tax compensation, up to a statutory annual limit, which was $18,500 for employees under age 50, and $24,500 for employees age 50 and over in 2018. The 401(k) Plan also permits us to make
discretionary contributions and matching contributions, subject to established limits and a vesting schedule. In 2013, we began making discretionary matching contributions, which for 2018, consisted of a match of 50% of up to the first 6% of
eligible compensation contributed by each employee toward his or her 401(k) plan.

Additional Benefits

The NEOs are eligible to participate in our benefit plans generally available to all employees, as described in Compensation Discussion and AnalysisKey
Components and Design of the Executive Compensation Program.

Pension Benefits

Other than with respect to tax-qualified defined contribution plans such as the 401(k) Plan, the NEOs do not participate in any
plan that provides for retirement payments and benefits, or payments and benefits that will be provided primarily following retirement.

Nonqualified Deferred
Compensation

During the year ended December 31, 2018, the NEOs did not contribute to, or earn any amounts with respect to, any defined contribution or
other plan sponsored by us that provides for the deferral of compensation on a basis that is not tax-qualified.

Potential Payments upon Termination or Change in Control

Amended and Restated Executive Change in Control and Severance Benefit Plan

The change in control plan provides that, in the event that an executives employment terminates due to an involuntary termination without cause or a constructive
termination, in each case upon or within 12 months following a change in control (as such terms are defined in the change in control plan and described generally below), and assuming all of the other conditions of the change in control plan are met,
each executive who is a participant in the change in control plan (including each of our NEOs) would be entitled to the following benefits under the change in control plan:



| |  | A single, lump sum cash severance payment equal to the sum of: (i) the applicable base salary described below,
multiplied by the applicable percentage set forth below; plus (ii) the product of (A) the applicable base salary, (B) the applicable bonus percentage described below and (C) the applicable percentage set forth below;
plus (iii) the product of (A) the applicable base salary, (B) the applicable bonus percentage and (C) the quotient obtained by dividing the number of full months that an executive is employed in the year of the termination
by 12.
|- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ¡ |  | The applicable base salary is the higher of the executives base salary in effect (i) on the date of
termination (without giving effect to any reduction in base salary that would constitute grounds for a constructive termination) or (ii) immediately prior to the change in control, without giving effect to any voluntary pay reduction taken by
the executive during the 12 months preceding the date of termination or the change in control.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ¡ |  | The applicable percentage is 200% for our CEO, executive chairman or president, 150% for senior vice presidents
and above and 100% for vice presidents.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

| | ¡ |  | The applicable bonus percentage is the greater of (i) the highest amount of any annual bonus paid to the
executive for either of the last two calendar years prior to (A) the date of termination or (B) the change in control, in each case expressed as a percentage of the executives base salary for the applicable year, and (ii) the
higher of the executives target bonus for the calendar year in which (A) the termination occurs or (B) the change in control occurs, in each case expressed as a percentage of the executives base salary for such year.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | Full payment of all of the applicable COBRA premiums for any health, dental or vision plan sponsored by us for a period of
up to (i) 24 months for our CEO, executive chairman or president, (ii) 18 months for executive vice presidents and senior vice presidents, and (iii) 12 months for vice presidents, provided that the executive timely elects continued
coverage.
|- |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | Acceleration in full of the vesting and exercisability, as applicable, of outstanding stock options and other equity awards
held by the executive.
|- |  | --------------------------------------------------------------------------------------------------------------------------------------------------

The following key terms are defined in the change in control plan:



| |  | A change in control generally means: (i) a person or group acquires ownership of more than 30% of the
combined voting power of our outstanding securities (other than directly from our company); (ii) certain compromises or arrangements sanctioned by the Irish courts, certain schemes, contracts or offers that have become binding on all of our
shareholders, certain takeover bids, certain offers or reverse takeover transactions, or a reorganization, merger, statutory share exchange, consolidation or similar transaction involving us, after which our shareholders do not own more than 50% of
the combined voting power of the surviving entity or its parent in substantially the same proportion as their ownership of our outstanding voting securities immediately before the transaction, or a person or group acquires ownership of more than 30%
of the combined voting power of the surviving entity or its parent, or at least a majority of the members of the board of directors of the parent (or the surviving entity, if there is no parent) following such transaction are not incumbent board
members (as defined in (v) below) at the time our board of directors approves the transaction; (iii) our shareholders or our board of directors approves a complete dissolution or liquidation of our company, or a complete dissolution or
liquidation of our company otherwise occurs (except for a liquidation into a parent company); (iv) a sale, lease, exclusive license or other disposition of all or substantially all of our assets, other than to certain entities; or
(v) individuals who were members of our board of directors as of February 10, 2016 (or members of our board of directors approved or recommended by a majority vote of such members still in office), referred to as incumbent board
members, cease to constitute at least a majority of the board of directors.

| |  | An involuntary termination without cause generally means an executives employment is terminated for any
reason other than for the following reasons: (i) the executives unauthorized use or disclosure of confidential information or trade secrets which causes material harm to us; (ii) the executives material breach of any agreement
with us (or the executives material violation of any statutory duty owed to us) after an opportunity to cure; (iii) the executives material failure to comply with our written policies or rules after an opportunity to cure;
(iv) the executives conviction or plea of guilty or no contest to any crime involving fraud, dishonesty or moral turpitude; (v) the executives gross misconduct; (vi) the executives continued failure to perform his or
her assigned duties after notification; or (vii) the executives failure to reasonably cooperate in good faith with any governmental or internal investigation of us or our directors, officers or employees. An involuntary termination
without cause also includes an executives termination of employment due to death or disability.

| |  | A constructive termination generally means an executive resigns employment after any of the following actions
are taken or events occur without the executives written consent: (i) one or more reductions in the executives base salary that results in a total reduction in the executives base salary, as in effect immediately prior to the
change in control or any higher base salary in effect following the change in control, by more than 10%; (ii) a relocation of the executives principal place of employment that increases the executives
one-way commute by more than 35 miles; (iii) a substantial reduction in the executives authority, duties or responsibilities that are in effect immediately prior to the change in control, provided
that if the executive holds the same position but the size of the executives employing entity or business unit has decreased significantly or our company or the executives employing entity ceases to be a publicly-traded corporation, the
executives authority, duties and responsibilities will be considered to be substantially reduced; (iv) a reduction in the executives title; or (v) a substantial increase in executives required business travel as compared
with the executives required business travel prior to the change in control.
|- |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

We benefit by requiring the executive to execute an effective
general waiver and release of claims in order to be eligible to receive benefits under the change in control plan. All other benefits (such as life insurance, disability coverage and 401(k) Plan eligibility) will terminate as of the executives
termination date.

The change in control plan does not provide for the gross up of any excise taxes imposed by section 4999 of the Code. If any of the severance
benefits payable under the change in control plan would constitute a parachute payment within the meaning of section 280G of the Code, subject to the excise tax imposed by section 4999 of the Code, the change in control plan
provides for a best after-tax analysis with respect to such payments, under which the executive will receive

whichever of the following two alternative forms of payment would result in executives receipt, on an after-tax basis, of the greater amount of the
transaction payment notwithstanding that all or some portion of the transaction payment may be subject to the excise tax: (i) payment in full of the entire amount of the transaction payment, or (ii) payment of only a part of the
transaction payment so that the executive receives the largest payment possible without the imposition of the excise tax.

The executive would not receive benefits
under the change in control plan in certain circumstances, including if (i) the executive voluntarily terminates employment with us to accept employment with another entity that is controlled, directly or indirectly, by us or is otherwise
affiliated with us; (ii) the executive does not confirm in writing that he or she is subject to agreements with us relating to proprietary and confidential information and our code of conduct; or (iii) the executive does not return all
company property. In addition, benefits would be terminated under the change in control plan if the executive willfully breaches his or her agreements with us relating to proprietary and confidential information or our code of conduct or engages in
certain solicitation or business interference activities.

The structure and amount of benefits provided under the change in control plan are intended to balance our
goals of attracting and retaining highly qualified individuals, providing the appropriate incentive for such individuals to perform in the best interests of our shareholders and maintaining responsible pay practices. Our compensation committee
periodically reviews market data to gain a general understanding of the change in control benefits offered by our competitors and reviews the benefits offered under the change in control plan against such market data to ensure that the benefits
under the change in control plan remain appropriate.

Equity Compensation Plans

The 2011 Plan and 2007 Plan and award agreements thereunder provide for potential vesting acceleration upon an executives termination in connection with a change
in control and, at the discretion of the board of directors, upon certain change in control events, as further described above under the heading Description of Compensation ArrangementsEquity Compensation Arrangements. In
addition, under the terms of the 2011 Plan and 2007 Plan and the option award agreements thereunder, the vested portion of stock options granted to the NEOs will generally expire three months after the applicable NEOs termination of service,
subject to extension under limited circumstances such as if the sale of shares during such time was prohibited by our insider trading policy or if exercise would result in violation of securities registration requirements. We refer to the period
following the NEOs termination during which he or she can continue to exercise his or her vested stock options as the post-termination exercise period. However, in termination situations involving the death or disability of an NEO, the
post-termination exercise period is generally extended up to 12 months in connection with a termination due to disability and up to 18 months in connection with a termination due to death. As the value of such extended post-termination exercise
periods is not quantifiable, such value is not included in the table below.

Potential Payments upon Termination or Change in Control Table

The following table estimates the potential severance payments and benefits under the change in control plan to which the NEOs would have been entitled in connection
with specified termination events, calculated as if each NEOs employment had terminated as of December 31, 2018. In addition, the table sets forth the amounts to which the NEOs would have been entitled under the 2011 Plan and 2007 Plan
if, upon a corporate transaction or change in control transaction, the board of directors had exercised its discretion to accelerate the vesting and exercisability of stock options and the vesting of RSU awards, and such event had occurred on
December 31, 2018.

There are no other agreements, arrangements or plans that entitle any NEOs to severance, perquisites or other benefits upon termination of
employment or a change in control. For purposes of the table below, we have assumed that none of the potential severance benefits payable under the change in control plan would be subject to the excise tax imposed by section 4999 of the Code
and therefore would not be reduced in accordance with the terms of the change in control plan.

|(1) | These benefits would be payable under the change in control plan if the involuntary termination without cause or
constructive termination occurred upon or within 12 months following a change in control and assuming such termination took place on December 31, 2018. The forms of stock option and RSU agreements under the 2011 Plan and the 2007 Plan provide
for the same vesting acceleration benefit as shown here under the change in control plan, therefore no separate vesting acceleration benefit is listed. Pursuant to the change in control plan, an involuntary termination without cause also includes an
individuals death or disability.

|(2) | These benefits would be payable under the 2011 Plan and the 2007 Plan if, upon a corporate transaction event, the board of
directors exercised its discretion to accelerate the vesting and exercisability of outstanding stock options and RSU awards, assuming the vesting acceleration took place on December 31, 2018. For a description of the potential vesting
acceleration provisions in the 2011 Plan and the 2007 Plan, see Description of Compensation ArrangementsEquity Compensation Arrangements above.

|(3) | The value of stock option and RSU award vesting acceleration is based on the closing price of $123.96 per ordinary share
as of December 31, 2018, minus, in the case of stock options, the exercise price of the unvested stock option shares subject to acceleration.

|(4) | Ms. Hooper resigned from her position as Executive Vice President and GC, effective as of March 1, 2019. There
were no severance payments or other severance benefits provided to Ms. Hooper resulting from her resignation, though Ms. Hooper continues to be employed by us as a part-time, non-executive employee
during a transition period.

Pay Ratio Disclosure

Under SEC rules, we are required to calculate and disclose the annual total compensation of our median employee, as well as the ratio of the annual total compensation of
our median employee as compared to the annual total compensation of our CEO, or our CEO pay ratio. Consistent with the process adopted for 2017, to identify our median employee for 2018, we used the following methodology:



| |  |  | To determine our total population of employees, we included all full-time, part-time, regular and temporary employees as of
October 1, 2018.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | To identify our median employee from our employee population, we calculated the annual target amount of each
employees 2018 base salary (using a reasonable estimate of the hours worked and no overtime for hourly employees) and bonus or commission, as applicable, and added the estimated value of all equity awards granted during 2018. For purposes of
base salaries, bonuses and commissions, we used an estimate based on the rates in effect on October 1, 2018. To estimate the value of stock options, we multiplied the number of shares subject to each stock option by the estimated per share
Black-Scholes value based on assumptions disclosed in our 2018 Annual Report on Form 10-K, and to estimate the value of other equity awards, we used the same methodology we use for reporting the value of
equity awards granted to our NEOs in our Summary Compensation Table.

| |  |  | In making this determination, we annualized the base salaries, bonuses and commissions of employees who were employed by us
for less than the entire calendar year.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Compensation paid in foreign currencies was converted to U.S. dollars based on the average daily exchange rates for the
year to date period ending on October 1, 2018.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------

Using this approach, we determined our median employee and then calculated the annual total
compensation of this employee for 2018 in accordance with the requirements of the Summary Compensation Table.

For 2018, the median of the annual total compensation
of our employees (other than our CEO) was $216,797 and the annual total compensation of our CEO, as reported in our Summary Compensation Table, was $11,443,133. Based on this information, the ratio of the annual total compensation of our CEO to the
median of the annual total compensation of all employees was 53 to 1.

The CEO pay ratio above represents our reasonable estimate calculated in a manner consistent
with SEC rules and applicable guidance. SEC rules and guidance provide significant flexibility in how companies identify the median employee, and each company may use a different methodology and make different assumptions particular to that company.
As a result, and as explained by the SEC when it adopted these rules, in considering the pay ratio disclosure, shareholders should keep in mind that the rule was not designed to facilitate comparisons of pay ratios among different companies, even
companies within the same industry, but rather to allow shareholders to better understand and assess each particular companys compensation practices and pay ratio disclosures.

Neither the compensation committee nor our management used our CEO pay ratio measure in making compensation decisions.

DIRECTOR COMPENSATION

Non-Employee Director Compensation Policy

Pursuant to our non-employee director compensation policy, or director compensation policy, each
non-employee director was entitled to receive the following cash compensation for board services, as applicable, for 2018:



| |  | a $60,000 annual retainer for service as a member of our board of directors (paid quarterly);
|- |  | ---------------------------------------------------------------------------------------------



| |  | a supplemental $50,000 annual retainer for service as the Lead Independent Director (paid quarterly);
|- |  | -----------------------------------------------------------------------------------------------------



| |  | a supplemental annual retainer for the chairs of the following board committees in the following amounts: $25,000 for the
chairperson of the audit committee, $22,500 for the chairperson of the compensation committee, $20,000 for the chairperson of the nominating and corporate governance committee and $22,500 for the chairperson of the transaction committee (each paid
quarterly); and
|- |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | a supplemental annual retainer for each member of the following board committees other than the chairs, in the following
amounts: $15,000 for service as a member of the audit committee, $12,500 for service as a member of the compensation committee, $10,000 for service as a member of the nominating and corporate governance committee and $12,500 for service as a member
of the transaction committee (each paid quarterly).
|- |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Our director compensation policy was originally approved by our board of directors in May 2013
and has been amended as follows: in August 2013 to, among other things, provide for cash retainers for the chairperson and members of the transaction committee; in May 2014 to provide for compensation to our Lead Independent Director and revise the
number of initial and continuing equity grants; in October 2014 to provide for a tax equalization payment on any Irish tax that may be paid on company reimbursement of reasonable travel, lodging and meal expenses related to service on the board of
directors; in April 2015 to revise the number of initial and continuing equity grants; in May 2016 to increase the annual retainer for service as a member of our board of directors, increase the annual retainer for service as our Lead Independent
Director and revise the number of initial and continuing RSU awards; and in May 2018 to replace the fixed number of initial and continuing option and RSU awards with a specified grant date dollar value.

The director compensation policy currently provides for the automatic grant of equity awards to our non-employee directors over
the period of their service on our board of directors. Any individual who first becomes a non-employee director is automatically granted the following: (a) an initial option to purchase ordinary shares
that vests with respect to one-third of the shares on the first anniversary of the date of such individuals election or appointment to the board of directors, and, with respect to the balance, in a
series of 24 successive equal monthly installments thereafter and (b) an initial RSU award that vests in equal annual installments over three years from the date of such individuals election or

##### Table of Contents

appointment to the board of directors, subject in each case to the non-employee directors continuous service through such dates. The grant date value
of the initial option together with the initial RSU award is equal to approximately $600,000, with generally 50% of the value delivered as an initial option and 50% of the value delivered as an initial RSU award, using the applicable ratio of stock
option grants to RSUs that is approved by the compensation committee on an annual basis, with the actual share amounts for the initial option and initial RSU award to be determined by applying the value methodology used by the compensation committee
for determining equity grants for employees generally. If a non-employee director does not stand for reelection at an annual general meeting of our shareholders in the year in which his or her term expires or
otherwise resigns effective at an annual general meeting of our shareholders and, in either case, the non-employee directors continuous service terminates at such meeting, then effective as of the date
of such meeting, any unvested portion of the initial option award will become vested and exercisable, and any unvested portion of the initial RSU award will become vested, in each case with respect to the portion of the award that would have vested
through the anniversary of the awards vesting commencement date in the year of that meeting.

Under the current director compensation policy, each continuing non-employee director will automatically be granted the following continuing grants in connection with each annual general meeting: (a) a continuing option to purchase ordinary shares that vests in a series of
12 successive equal monthly installments beginning on the first day of the calendar month following the date of the annual general meeting of our shareholders with respect to which the option is granted and (b) a continuing RSU award that vests
in full on the first anniversary of the date of the annual general meeting of our shareholders with respect to which the RSU award is granted, subject in each case to the non-employee directors
continuous service through such dates. The grant date value of the continuing option together with the continuing RSU award is equal to approximately $400,000, with generally 50% of the value delivered as a continuing option and 50% of the value
delivered as a continuing RSU award, using the applicable ratio of stock option grants to RSUs that is approved by the compensation committee on an annual basis, with the actual share amounts for the continuing option and continuing RSU award to be
determined by applying the value methodology used by the compensation committee for determining equity grants for employees generally. If a director is elected or appointed as a director for the first time other than at an annual general meeting, in
order to receive automatic continuing grants, the director must have first joined the board at least four calendar months before the date of the applicable annual general meeting. If a director is elected or appointed as a director for the first
time at an annual general meeting, the director will not receive automatic continuing grants for such meeting. If a non-employee director does not stand for reelection at an annual general meeting of our
shareholders in the year in which his or her term expires or otherwise resigns effective at an annual general meeting of our shareholders and, in either case, the non-employee directors continuous
service terminates at such meeting, then effective as of the date of such meeting, any unvested portion of the continuing option award will become vested and exercisable in full and any unvested portion of a continuing RSU award will become vested
in full.

The automatic initial and continuing options and RSU awards are granted under the Amended and Restated 2007
Non-Employee Directors Stock Award Plan, or 2007 Directors Plan.

The grant date of these equity awards is the second trading
day following the filing date of our next quarterly or annual report filed under the Exchange Act that occurs after the date the director first joined our board of directors (with respect to the automatic initial option and RSU awards) or the date
of our annual general meeting (with respect to the automatic continuing option and RSU awards). The other terms and conditions applicable to equity awards made to our non-employee directors are included below
under the heading Equity Compensation Plans.

In addition, our non-employee directors are reimbursed for
travel and other reasonable expenses incurred in attending board or committee meetings, as are our employees who serve as directors. If any reimbursement payment is subject to tax imposed by the Irish Revenue Commissioners, each non-employee director is also entitled to a tax equalization payment in order to allow them to retain the full reimbursement payment.

Directors Continuing Education

In furtherance of our ongoing commitment to
the continuing education of our directors, our nominating and corporate governance committee adopted a policy for the reimbursement of director continuing education in February 2013, as amended in February 2014. Under this policy, we will pay or
reimburse each director for enrollment fees and reasonable expenses incurred in connection with attending and participating each year in one director continuing education program and in one healthcare industry continuing education program, each
sponsored by an outside provider.

Directors Deferred Compensation Plan

In May 2007, the Jazz Pharmaceuticals, Inc. board of directors adopted the Directors Deferred Compensation Plan, which was amended and restated in August 2010. The
Directors Deferred Compensation Plan, as amended and restated, is referred to in this report as the Directors Deferred Plan. We continued and assumed the Directors Deferred Plan in connection with the Azur Merger. The Directors Deferred Plan allows
each non-employee director to elect to defer receipt of all or a portion of his or her annual retainer fees to a future date or dates. Amounts deferred under the Directors



46

##### Table of Contents

Deferred Plan are credited as our ordinary shares to a phantom stock account, and the number of shares credited is based on the amount of the retainer fees deferred divided by the market value of
our ordinary shares on the first trading day of the first open window period following the date the retainer fees were deemed earned. On the tenth business day following the day of separation from the board of directors or the occurrence of a change
in control, or as soon thereafter as practical once the non-employee director has provided the necessary information for electronic deposit of the deferred shares, each
non-employee director will receive (or commence receiving, depending upon whether the director has elected to receive distributions from his phantom stock account in a lump sum or in installments over time) a
distribution from his phantom stock account in our ordinary shares. The Directors Deferred Plan may be amended or terminated at any time by the board of directors. The Directors Deferred Plan in form and operation is intended to be compliant with
section 409A of the Code.

Although we continue to maintain the Directors Deferred Plan, since the closing of the Azur Merger we have not permitted our non-employee directors to defer any annual retainer fees under the Directors Deferred Plan.

Ownership Guidelines for Directors

We maintain share ownership guidelines for our non-employee directors, originally adopted in February 2013 and
amended in May 2018. Under the guidelines, giving effect to an amendment in May 2018, each non-employee director is expected to own a number of the companys ordinary shares with a value equal to
five times his or her annual cash retainer (increased from three times the annual cash retainer prior to May 2018). The guidelines provide that the individuals subject to the guidelines are expected to establish the minimum ownership levels within
five years of first becoming subject to the guidelines (and, with respect to the amended guidelines in May 2018, by the last day of 2021 for individuals subject to the guidelines as of January 1, 2018). As of March 31, 2019, each non-employee director was in compliance with his or her share ownership requirement under the guidelines, except for Ms. ORiordan who joined our board of directors in February 2019 and,
accordingly, has five years from her appointment, or until 2024, to comply with the guidelines.

Equity Compensation Plans

The 2007 Directors Plan, which was initially adopted by the Jazz Pharmaceuticals, Inc. board of directors and approved by the Jazz Pharmaceuticals, Inc. stockholders in
connection with its initial public offering, was continued and assumed by us upon the consummation of the Azur Merger. The automatic initial and continuing stock awards under our director compensation policy described above are granted under the
2007 Directors Plan.

With respect to options granted under the 2007 Directors Plan and 2007 Plan, if a non-employee
directors service relationship with us or any of our affiliates, whether as a non-employee director or subsequently as our employee, director or consultant or that of any of our affiliates, ceases for
any reason other than disability or death, or, with respect to options granted under the 2007 Directors Plan only, after any 12-month period following a change in control, the optionee may exercise any vested
options for a period of three months following the cessation of service. If such optionees service relationship with us, or any of our affiliates, ceases due to disability or death (or an optionee dies within a certain period following
cessation of service), the optionee or a beneficiary may exercise the option for a period of 12 months in the event of disability, and 18 months in the event of death. With respect to options granted under the 2007 Directors Plan, if such
optionees service terminates within 12 months following a specified change in control transaction, the optionee may exercise any vested portion of the option for a period of 12 months following the effective date of such a transaction. The
option term may be extended in the event that exercise of the option following termination of service is prohibited by applicable securities laws. In no event, however, may an option be exercised beyond the expiration of its term.

With respect to RSU awards granted under the 2007 Directors Plan and 2007 Plan, if a non-employee directors service
relationship with us or any of our affiliates, whether as a non-employee director or subsequently as our employee, director or consultant or that of any of our affiliates, ceases for any reason, any RSU awards
that were unvested as of the date of such termination will be forfeited.

In the event of certain significant corporate transactions (which generally have a meaning
similar to corporate transaction under the 2011 Plan), all outstanding awards under the 2007 Directors Plan may be assumed, continued or substituted for by any surviving or acquiring entity (or its parent company). If the surviving or
acquiring entity (or its parent company) elects not to assume, continue or substitute for such awards, then (a) with respect to any such awards that are held by participants then performing services for us or our affiliates, the vesting and
exercisability of such awards will be accelerated in full and such awards will be terminated if not exercised (if applicable) prior to the effective date of the corporate transaction and (b) all other outstanding awards will terminate if not
exercised prior to the effective date of the corporate transaction. The board of directors may also provide that the holder of an outstanding award not assumed in the corporate transaction will surrender such award in exchange for a payment equal to
the excess of (i) the value of the property that the holder would have received upon exercise of the award, over (ii) the exercise price otherwise payable in connection with the exercise. In addition, the vesting and exercisability of
awards under the 2007 Directors Plan held by

non-employee directors who are either required to resign their position as a condition of a specified change in control transaction (which generally has a
similar meaning as a change in control under the 2011 Plan) or are removed from their position in connection with such a change in control will be accelerated in full.

The treatment of outstanding options and RSU awards under the 2007 Plan in the event of certain significant corporate transactions or a specified change in control
transaction is described above under the heading Executive CompensationDescription of Compensation ArrangementsEquity Compensation Arrangements2007 Equity Incentive Plan.

2018 Equity Grants

In accordance with our
non-employee director compensation policy described above, we made automatic continuing grants to each of our non-employee directors as a result of their continuing on
the board of directors through our annual general meeting in August 2018, which continuing grants were comprised of an option to purchase 3,735 ordinary shares and an RSU award covering 1,495 ordinary shares. All options and RSUs granted to non-employee directors during 2018 were granted under the 2007 Directors Plan.

Director Compensation Table

The following table sets forth certain information with respect to the compensation of all of our non-employee directors for the
fiscal year ended December 31, 2018.

Mr. Cozadd, our Chairman and CEO, is not listed in the following table because he is our employee.
Mr. Cozadds compensation is described under Executive Compensation. Mr. Cozadd received no additional compensation for serving on our board of directors in 2018. In addition, Ms. ORiordan, who joined our
board of directors in February 2019, is not listed in the following table since she received no compensation from Jazz Pharmaceuticals in any capacity during the fiscal year ended December 31, 2018.

|(1) | The dollar amounts in this column represent each non-employee directors
actual annual cash retainer earned for board services in 2018, which is equal to the aggregate of his or her annual retainer of $60,000 plus his or her annual retainers for service on one or more board committees, and for Mr. Winningham, for
service as Lead Independent Director. Each non-employee directors total fees were earned and payable in four quarterly installments subject to the non-employee
directors continuous service at the end of each quarter. Fees paid to each of Ms. McSharry and Messrs. Gray, Mulligan and Schnee were paid in Euro. The conversion to U.S. dollars was calculated based on the average exchange rate for each
quarter as reported by the OANDA Corporation. Following the Azur Merger, the board of directors did not permit cash retainer fees to be deferred by our non-employee directors pursuant to the Directors Deferred
Plan. The total number of ordinary shares previously credited to each individual non-employee directors phantom stock account under the Directors Deferred Plan as of December 31, 2018 was as
follows: 4,691 shares for Mr. Berns; 9,929 shares for Mr. Enright; 22,249 shares for Mr. OKeefe; and no shares for the other non-employee directors.

|(2) | The dollar amounts in this column reflect the aggregate grant date fair value of RSU awards computed in accordance with
ASC 718. The grant date fair value of each RSU award is measured based on the closing price of our ordinary shares on the date of grant. These amounts do not necessarily correspond to the actual value recognized or that may be recognized by the non-employee directors.

|(3) | The aggregate number of shares subject to outstanding stock options and RSU awards held by the non-employee directors listed in the table above as of December 31, 2018 was as follows: 26,280 shares subject to outstanding stock options and 1,495 shares subject to outstanding RSUs for each of Messrs. Berns
and Mulligan; 7,150 shares subject to outstanding stock options and 1,495 shares subject to outstanding RSUs for Mr. Enright; 29,780 shares subject to outstanding stock options and 1,495 shares subject to outstanding RSUs for Dr. Sohn;
21,780 shares subject to outstanding stock options and 1,495 shares subject to outstanding RSUs for Mr. OKeefe; 25,280 shares subject to outstanding stock options and 1,495 shares subject to outstanding RSUs for each of Ms. McSharry,
Mr. Gray and Dr. Riedel; 17,280 shares subject to outstanding stock options and 1,495 shares subject to outstanding RSUs for Mr. Winningham; and 18,980 shares subject to outstanding stock options and 1,495 shares subject to

Compensation Committee Report(1)

The compensation committee has reviewed and discussed with management the Compensation Discussion and Analysis contained herein. Based on this review and discussion, the
compensation committee has recommended to the board of directors that the Compensation Discussion and Analysis be included in our proxy statement for the 2019 annual general meeting of shareholders and be included in the companys Annual Report
on Form 10-K we filed with the SEC for the fiscal year ended December 31, 2018.

Respectfully submitted,

The Compensation Committee of the Board of Directors

Dr. Norbert G. Riedel, Ph.D. (Chair)

Mr. Paul L. Berns

Mr. Patrick G. Enright

Dr. Catherine A. Sohn,Pharm.D.

and is not to be incorporated by reference in any filing of the registrant under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended, whether made before or after the date hereof and irrespective of any general

Compensation Committee Interlocks and Insider Participation

During 2018, our compensation committee was composed of four directors: Messrs. Berns and Enright, Dr. Riedel and Dr. Sohn. During 2018, none of the members of
our compensation committee was at any time our officer or employee. None of our executive officers serve, or in the past fiscal year served, as a member of the board of directors or the compensation committee of any entity that has one or more of
its executive officers serving on our board of directors or compensation committee.

Compensation Consultant Fees

The compensation committee engages an independent compensation consultant each year to provide a competitive compensation assessment with respect to the executive
officers to assist the compensation committee in making annual compensation decisions. Since 2010, Radford has been engaged by the compensation committee each year to provide peer company and industry compensation data and provide the compensation
committee with advice regarding executive officers compensation, including base salaries, performance-based bonuses and long-term equity compensation, and similar advice regarding directors compensation. In 2018, the cost of
Radfords executive compensation and director compensation consulting services provided to the compensation committee was approximately $204,000. In addition, in 2018 management also engaged Radford to provide survey data relating to non-executive employee compensation and other affiliates of Aon to provide director and officer liability insurance-related services, pension-related services, other insurance brokerage services and risk services.
The aggregate cost of such other consulting services provided in 2018 by Radford and other affiliates of Aon (not related to Radfords executive compensation and director compensation consulting services provided to the compensation committee)
was approximately $97,000, of which approximately $86,000 related to various insurance-related and benefits consulting services and approximately $11,000 related to general survey data. Although the compensation committee was aware of the nature of
the services performed by affiliates of Aon and the non-executive employee compensation survey data provided by Radford, the compensation committee did not review and approve such services and surveys, as
those were reviewed and approved by management in the ordinary course of business.

|(1) | Each of the equity compensation plans set forth in this table was originally adopted by Jazz Pharmaceuticals, Inc. and
assumed and adopted by us in connection with the Azur Merger. In addition, each option that was outstanding under Jazz Pharmaceuticals, Inc.s equity compensation plans was converted into an option to acquire, on substantially the same terms
and conditions as were applicable under such option before the Azur Merger, the number of our ordinary shares equal to the number of shares of Jazz Pharmaceuticals, Inc.s common stock subject to such option immediately prior to the Azur
Merger, at an exercise price per ordinary share equal to the exercise price per share of Jazz Pharmaceuticals, Inc.s common stock otherwise purchasable pursuant to such option, and each other equity award that was outstanding under Jazz
Pharmaceuticals, Inc.s equity compensation plans was converted into a right to receive, on substantially the same terms and conditions as were applicable under such equity award before the Azur Merger, the number of our ordinary shares equal
to the number of shares of Jazz Pharmaceuticals, Inc.s common stock subject to such equity award immediately prior to the Azur Merger. Other than with respect to the Directors Deferred Plan, each of the equity compensation plans set forth in
this table was approved by Jazz Pharmaceuticals, Inc.s stockholders.

the disposition of 4,988,277 ordinary shares, and shared power to dispose or direct the disposition of 56,589 shares. The Schedule 13G/A also indicates that Vanguard Fiduciary Trust Company, a wholly-owned subsidiary of Vanguard, is the beneficial

P. Johnson. According to the Schedule 13G/A, as of December 31, 2018, FMR has sole power to vote or direct the vote of 301,552 ordinary shares and the sole power to dispose or direct the disposition of 4,734,301 ordinary shares, and
Ms. Johnson has the sole power to dispose or direct the disposition of 4,734,301 ordinary shares. The Schedule 13G/A indicates that FMR is acting as a parent holding company or control person for a number of its relevant entities that
beneficially owned the ordinary shares being reported, including FMR Co., Inc., an investment adviser reported as beneficially owning 5% or greater of our ordinary shares. In addition, Ms. Johnson is a Director, the Chairman, and the Chief
Executive Officer of FMR. Ms. Johnson and members of her family are the predominant owners, directly or through trusts, of Series B voting common shares of FMR, representing 49% of the voting power of FMR. The Johnson family group and all other
Series B shareholders have entered into a shareholders voting agreement under which all Series B voting common shares will be voted in accordance with the majority vote of Series B voting common shares. Accordingly, through their ownership of
voting common shares and the execution of the shareholders voting agreement, members of the Johnson family may be deemed, under the Investment Company Act of 1940, or Investment Company Act, to form a controlling group with respect to FMR.
Neither FMR nor Ms. Johnson has the sole power to vote or direct the voting of the shares owned directly by the various investment companies registered under the Investment Company Act, or the Fidelity Funds, advised by Fidelity
Management & Research Company, or FMRC, a wholly owned subsidiary of FMR, which power resides with the Fidelity Funds Boards of Trustees. FMRC carries out the voting of the shares under written guidelines established by the Fidelity
Funds Boards of Trustees. The Schedule 13G/A provides information only as of December 31, 2018 and, consequently, the beneficial ownership of the above-mentioned persons and entities may have changed between December 31, 2018 and

|Item 13. | Certain Relationships and Related Transactions, and Director Independence
|-------- | -------------------------------------------------------------------------

Policy and Procedures for Review of Related Party Transactions

We have
adopted a Related Party Transaction Policy that sets forth our procedures for the identification, review, consideration and approval or ratification of related-person transactions. For purposes of our policy, a related-person
transaction is a transaction, arrangement or relationship (or any series of similar transactions, arrangements or relationships) in which we are, were or will be a participant, and the amount involved exceeds $120,000, and any related
person had, has or will have a direct or indirect material interest (other than solely as a result of being a director or a beneficial owner of less than 10% of any class of a companys voting securities). Transactions involving
compensation for services provided to us as an employee or director are not covered by this policy. A related person is any executive officer, director or beneficial owner of more than 5% of any class of our voting securities, including
any of their immediate family members and any entity owned or controlled by such persons.

Under the policy, if a transaction has been identified as a related-person
transaction (including any transaction that was not a related-person transaction when originally consummated or any transaction that was not initially identified as a related-person transaction prior to consummation), our management must present
information regarding the related-person transaction to our audit committee (or, if audit committee approval would be inappropriate, to another independent body of our board of directors) for review, consideration and approval or ratification. The
presentation must include a description of, among other things, the material facts, the interests, direct and indirect, of the related person(s), the benefits to us of the transaction and whether the transaction is on terms that are comparable to
the terms available to or from, as the case may be, an unrelated third party or to or from employees generally. Under the policy, we will, on an annual basis, collect information that our GC deems reasonably necessary from each director, executive
officer and (to the extent feasible) significant shareholder to enable us to identify any existing or potential related-person transactions and to effectuate the terms of the policy. In addition, under our code of conduct, our employees and
directors have an affirmative responsibility to disclose any transaction or relationship that reasonably could be expected to give rise to a conflict of interest to our GC, or, if the employee is an executive officer, to our board of directors. In
considering related-person transactions, our audit committee (or other independent body of our board of directors) will take into account the relevant available facts and circumstances including, but not limited to, the risks, costs and benefits to
us, the terms of the transaction, the availability of other sources for comparable services or products and, if applicable, the impact on a directors independence in the event that the related person is a director, immediate family member of a
director or an entity with which a director is affiliated.

##### Table of Contents

The policy requires that, in determining whether to approve, ratify or reject a related-person transaction, our audit
committee (or other independent body of our board of directors) must consider, in light of known circumstances, whether the transaction is in, or is not inconsistent with, our best interests and those of our shareholders, as our audit committee (or
other independent body of our board of directors) determines in the good faith exercise of its discretion.

Transactions with Related Persons; Indemnification

Transactions with Related Persons.Since January 1, 2018, we have not engaged in any transactions, nor are any such transactions currently proposed,
in which we were a participant and the amount involved exceeded $120,000, and in which any related person had or will have a direct or indirect material interest.

Indemnification. We have entered into indemnification agreements with our directors, executive officers and certain other of our officers and employees. These
indemnification agreements require us, under the circumstances and to the extent provided for therein, to indemnify such persons to the fullest extent permitted by applicable law against certain expenses and other amounts incurred by any such person
as a result of such person being made a party to certain actions, suits, proceedings and other actions by reason of the fact that such person is or was a director, officer, employee, consultant, agent or fiduciary of our company or any of our
subsidiaries or other affiliated enterprises. The rights of each person who is a party to an indemnification agreement are in addition to any other rights such person may have under our Amended and Restated Memorandum and Articles of Association,
the Irish Companies Act 2014, any other agreement, a vote of the shareholders of our company, a resolution of directors of our company or otherwise. We believe that these agreements are necessary to attract and retain qualified persons as our
officers and directors. We also maintain directors and officers liability insurance.

Director Independence

As required under the Nasdaq listing standards, a majority of the members of a listed companys board of directors must qualify as independent, as
affirmatively determined by the board of directors. Our board of directors consults with counsel to ensure that the boards determinations are consistent with relevant securities and other laws and regulations regarding the definition of
independent, including those set forth in the applicable Nasdaq listing standards, as in effect from time to time. Consistent with these considerations, after review of all relevant transactions or relationships between each director, or
any of his or her family members, and our company, our senior management and our independent registered public accounting firm, the board of directors affirmatively determined that all of our current directors are independent directors within the
meaning of the applicable Nasdaq listing standards, except that Mr. Cozadd, our Chairman and CEO, is not independent by virtue of his employment with our company. In addition, our board of directors has determined that each member of the audit
committee, compensation committee and nominating and corporate governance committee meets the applicable Nasdaq and SEC rules and regulations regarding independence and that each member is free of any relationship that would impair his
or her individual exercise of independent judgment with regard to the company. In determining that Seamus Mulligan is independent within the meaning of the applicable Nasdaq listing standards, the Board considered Mr. Mulligans former
employment relationship with us, which ended more than six years ago.

##### Table of Contents

Audit Fees: Consists of fees and expenses for professional services in respect of the audit of the companys
consolidated financial statements and of our internal control over financial reporting, the review of quarterly consolidated financial statements and statutory audits.

Audit-Related Fees: Consists of fees for assurance and services related to audit and other attestation services performed by KPMG as required by statute,
regulation or contract and which are not reported under Audit Fees.

Tax Fees: Consists of fees and expenses for professional services for tax
compliance, tax advice and tax planning. Tax compliance services consist of professional services related to domestic and international tax compliance, and assistance with domestic and international tax return preparation. Tax advisory service fees
relate to tax advice and planning services provided to us in connection with certain transactions undertaken by the company in 2018 and 2017. During the year ended December 31, 2018, fees and expenses of approximately $930,000 were billed in
connection with tax compliance services, and fees and expenses of approximately $16,000 were billed in connection with tax advice and planning services. During the year ended December 31, 2017, fees and expenses of approximately $1,000,000
were billed in connection with tax compliance services, and fees and expenses of approximately $119,000 were billed in connection with tax advice and planning services.

All Other Fees: Consists of fees for products and services other than the services described above. For the year ended December 31, 2018, these fees were
paid in connection with access to the online accounting and tax research tool of KPMG. For the year ended December 31, 2017, these fees were paid in connection with forensic accounting services and access to the online accounting and tax
research tool of KPMG.

All of the services and fees described above were approved by our audit committee.

As shown in the table above, less than 1% of the total fees that KPMG billed us for in 2018 were for services other than audit, audit-related and tax compliance
services.

Pre-Approval Policies and Procedures

Our audit committee has a policy and procedures for the pre-approval of audit and
non-audit services rendered by our independent registered public accounting firm. Our policy generally requires the pre-approval of specified services in the defined
categories of audit services, audit-related services, and tax services up to specified amounts. Pre-approval may also be given as part of the audit committees approval of the scope of the engagement of
the independent auditor or on an individual explicit case-by-case basis before the independent auditor is engaged to provide each service. The pre-approval of services
may be delegated to one or more of the audit committees members, but the decision must be reported to the full audit committee at its next scheduled meeting.

Our audit committee determined that the rendering of the services other than audit services by our independent registered public accounting firm is compatible with
maintaining the principal accountants independence.
