3.TERMINATION AND SEVERANCE

1.Termination.

(a)Nothing in this Agreement shall prevent the Company from terminating the Executive’s employment with the Company and this Agreement at any time, with or without “Cause.” “Cause” means: (i) conviction of the Executive of, or the Executive’s plea of nolo contendere to, a felony or crime involving moral turpitude; (ii) fraud, theft, or misappropriation by the Executive of any asset or property of any member of the Avadel Group of Companies, including, without limitation, any theft or embezzlement or any diversion of any corporate opportunity; (iii) breach by the Executive of any of the material obligations contained in this Agreement; (iv) conduct by the Executive materially contrary to the material policies of any member of the Avadel Group of Companies; (v) material failure by the Executive to meet the goals and objectives established by any member of the Avadel Group of Companies; provided that the Executive has failed to cure such failure within a reasonable period of time after written notice to him regarding such failure; or (vi) conduct by the Executive that results in a material detriment to any member of the Avadel Group of Companies, or its program, or goals or that is inimical to its reputation and interest; provided that the Executive has failed to cure such failure within a reasonable period of time after written notice to him regarding such conduct. Any reoccurrence of such acts constituting Cause within one (1) year of the original occurrence will require no such pre-termination right of the Executive to cure.

(b)The Executive may terminate the Executive’s employment with the Company and this Agreement for or other than for “Good Reason”. “Good Reason” means, without the Executive’s consent, any of the following: (i) the Company’s diminution in the Executive’s authority, duties or responsibilities with respect to Avadel plc or the Company in any material respect or the Company’s assignment to the Executive of duties or responsibilities that are materially inconsistent with the Executive’s position with Avadel plc or the Company as stated in this Agreement; (ii) a change in the location of the Executive’s employment which increases the Executive’s one-way commute by more than sixty (60) miles; or (iii) a material breach by the Company of this Agreement.

(c)In the event that the Executive desires to resign from the Company, he shall promptly give the Company written notice of the date that such resignation will be effective, provided that the notice period shall be no less than thirty (30) days; provided further, that the Company may unilaterally accelerate the date of termination and such acceleration shall not result in a termination by the Company for purposes of this Agreement. In the event that the Executive desires to resign from the Company for Good Reason, he shall provide the Company with written notice setting forth the acts constituting Good Reason within ninety (90) days of the initial occurrence of the Good Reason condition and providing that

the Company may cure such acts within thirty (30) days of receipt of such notice. If such condition is not remedied within such thirty- (30-) day cure period, any termination of employment by the Executive for “Good Reason” must occur within ninety (90) days after the period for remedying such condition has expired.

(d)In the event that the Company desires to terminate the Executive’s employment, with or without Cause, the Company shall give the Executive written notice thereof, and the termination shall be effective as of the date specified in the written notice.

(e)The Executive’s employment and this Agreement shall terminate automatically upon the Executive’s death. If the Company determines that the Executive is subject to an Incapacity (as hereinafter defined), the Company may terminate the Executive’s employment and this Agreement effective upon the Executive’s Incapacity. “Incapacity” shall mean the inability of the Executive to perform the essential functions of the Executive’s job, with or without reasonable accommodation, for a period of 90 days in the aggregate in any 180-day period.

(f)If the Executive’s employment is terminated for any reason, the Company shall pay to the Executive (or, after the Executive’s death, his estate) any accrued or awarded but unpaid annual bonus and accrued but unused vacation pay, expense reimbursement and other benefits due to the Executive under any Company-provided benefit plans, policies and arrangements, with such accrued but unpaid annual bonus and vacation pay and expense reimbursements payable no later than thirty (30) days after the date of termination of employment (sooner to the extent required by applicable law or to the extent the bonus is payable prior to such time) and any other benefits payable in accordance with the applicable terms of the benefit plans, policies and arrangements. The payments in this Section 3.1(f) are collectively referred to as the “Accrued Obligations.”

2.Severance. If the Executive terminates this Agreement and his employment with the Company for Good Reason or if the Executive’s employment with the Company is terminated by the Company without Cause or by non-renewal of this Agreement by the Company, the Company shall pay severance to the Executive as follows:

(i) severance pay in an amount equal to 1.0 times the Executive’s then-current annual base salary, such amount to be paid in a one-time installment; and

(ii) if the Executive elects continuation coverage pursuant to the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”), then the Company each month will pay for the Executive’s COBRA premiums for such coverage (at coverage levels in effect immediately prior to the Executive’s termination) until the earlier of: (A) the expiration of a period of twelve (12) months from the date of termination or (B) the date upon which the Executive becomes covered under similar plans of any subsequent employer or is otherwise ineligible for COBRA; provided, however, if the Company determines that it cannot pay such amounts to the group health plan provider or the COBRA provider (if applicable) without potentially violating applicable law (including, without limitation, Section 2716 of the Public Health Service Act), then the Company shall convert such payments to payroll payments directly to the Executive for the time period specified above. Such payments shall be subject to applicable tax-related deductions and withholdings and paid on the Company’s regular payroll dates.

All payments and benefits set forth in the foregoing items (i) and (ii) hereof are defined as the “Severance Pay and Benefits.” The Executive’s receipt of the foregoing Severance Pay and Benefits is conditioned upon his execution and delivery to the Company of a separation and release agreement acceptable to the Company governing the termination of the employment relationship between the Executive and the

Company and the Executive’s release of all claims against all members of the Avadel Group of Companies and their employees, officers, directors, contractors and other related persons (the “Separation and Release Agreement”), and allowing the applicable revocation period required by law to expire without revoking or causing revocation of same, within the time period set forth in the Separation and Release Agreement and in no event more than sixty (60) days following the date of termination of the Executive’s employment. The amounts payable under this Section 3.2, to the extent taxable, shall be paid or commence to be paid within 60 days after the Executive’s date of termination; provided, however, that if the 60-day period spans more than one calendar year, any payments that the Executive is entitled to receive during such period shall be accumulated and paid in a lump sum only in the subsequent calendar year.

3.Change of Control.

(a)If the Executive terminates this Agreement and his employment with the Company for Good Reason or if the Executive’s employment with the Company is terminated by the Company without Cause or by non-renewal of this Agreement by the Company, and such termination occurs during a Change of Control Period (as hereinafter defined), then, in addition to the Executive being eligible for the Severance Pay and Benefits, subject to the terms of Section 3.2 above, and notwithstanding any other provision in any applicable equity compensation plan and/or individual stock option plan or agreement, the Executive’s outstanding and vested stock options as of the Executive’s termination of employment date will remain exercisable until the eighteen (18) month anniversary of the termination of employment date; provided, however, that the post-termination exercise period for any individual stock option right will not extend beyond its original maximum term as of the original date of the grant (the “Extended Exercise Period”).

(b)The Executive’s receipt of the foregoing Extended Exercise Period is conditioned upon his execution and delivery to the Company of the Separation and Release Agreement within the time period set forth in the Separation and Release Agreement and in no event more than sixty (60) days following the date of termination of the Executive’s employment.

4.Relief. The Executive agrees that it would be difficult to measure any damages caused to the Company that might result from any breach by the Executive of any portion of Sections 4.1 through 4.3, and that in any event money damages would be an inadequate remedy for any such breach.

2.Severability. If any term or provision of this Agreement or any application of this Agreement shall be declared or held invalid, illegal, or unenforceable, in whole or in part, whether generally or in any particular jurisdiction, such provision shall be deemed amended to the extent, but only to the extent, necessary to cure such invalidity, illegality, or unenforceability, and the validity, legality, and enforceability of the remaining provisions, both generally and in every other jurisdiction, shall not in any way be affected or impaired thereby.

3.Survival. Notwithstanding any expiration or termination of this Agreement, Section 2.4(c) hereof, Section 4 hereof and this Section 5 shall survive such expiration or termination to the extent necessary to effectuate the terms contained herein.

4.Interpretation of Agreement.

(a)Unless otherwise indicated to the contrary herein by the context or use thereof: (i) the words, “herein,” “hereto,” “hereof,” and words of similar import refer to this Agreement as a whole and not to any particular Article, Section, subsection, or paragraph hereof; (ii) words importing the masculine gender shall include the feminine and neuter genders and vice versa; and (iii) words importing the singular shall include the plural, and vice versa.

This Agreement has been prepared by all parties equally, and is to be interpreted according to its terms. No inference shall be drawn that the Agreement was prepared by or is the product of any particular party or parties.

5.Taxes.

(a)The parties hereto acknowledge that the requirements of Section 409A of the Internal Revenue Code (“Section 409A”) are still being developed and interpreted by government agencies and that the parties hereto have made a good faith effort to comply with current guidance under Section 409A. Notwithstanding anything in this Agreement to the contrary, in the event that amendments to this Agreement are necessary in order to continue to comply with future guidance or interpretations under Section 409A, including amendments necessary to ensure that compensation will not be subject to tax under Section 409A (which may require deferral of severance or other compensation), the Company and the Executive agree to negotiate in good faith the applicable terms of such amendments and to implement such negotiated amendments, on a prospective and/or retroactive basis as needed. Further, to the extent any amount or benefit under this Agreement is subject to the requirements of Section 409A, then, with respect to such amount or benefit, this Agreement will be interpreted in a manner to comply with the requirements of Section 409A.

(b)Further, a termination of employment shall not be deemed to have occurred for purposes of any provision of this Agreement providing for the payment of any amounts or benefits upon or as a result of a termination of employment unless such termination is also a “separation from service” within the meaning of Section 409A and, for purposes of any such provision of this Agreement, references to a “termination”, “termination of employment”, “Termination Date”, or the like shall mean “separation from service”.

(c)For purposes of this Agreement, all rights to payments and benefits hereunder shall be treated as rights to receive a series of separate payments and benefits to the fullest extent allowed by Section 409A of the Code.

(d)If the Executive is a key employee (as defined in Section 416(i) of the Code without regard to paragraph (5) thereof) and any of Avadel’s securities are publicly traded on an established securities market or otherwise, then payment of any amount or provision of any benefit under this Agreement which is considered deferred compensation subject to Section 409A of the Code shall be deferred for six (6) months after termination of Executive’s employment or, if earlier, Executive’s death, if and as required by Section 409A(a)(2)(B)(i) of the Code (the “409A Deferral Period”). In the event such payments are

otherwise due to be made in installments or periodically during the 409A Deferral Period, the payments which would otherwise have been made in the 409A Deferral Period shall be accumulated and paid in a lump sum as soon as the 409A Deferral Period ends, and the balance of the payments shall be made as otherwise scheduled. In the event benefits are required to be deferred, any such benefit may be provided during the 409A Deferral Period at the Executive’s expense, with the Executive having a right to reimbursement from the Company once the 409A Deferral Period ends, and the balance of the benefits shall be provided as otherwise scheduled.

(e)To the extent that some portion of the payments under this Agreement may be bifurcated and treated as exempt from Code Section 409A under the “short-term deferral” or “separation pay” exemptions, then such amounts shall be so treated as exempt from Code Section 409A (and in particular, the earliest amounts to be paid under Section 3 of the Agreement will be first treated as exempt from Code Section 409A under the short-term deferral exemption and then the separation pay exemption to the extent available).

(f)Any reimbursements, in-kind benefits or offset provided under this Agreement that constitutes deferred compensation under Code Section 409A shall be made or provided in accordance with the requirement of Code Section 409A, including, where applicable, the requirement that (i) any reimbursement is for expense incurred during the period of time specified in this Agreement, (ii) the amount of expense eligible for reimbursement, or in-kind benefits, provided during a calendar year may not affect the expense eligible for reimbursement, or in-kind benefits to be provided, in any other calendar year, (iii) the reimbursement of an eligible expense will be made no later than the last day of the calendar year following the calendar in which the expense is incurred, and (iv) the right to reimbursement or in-kind benefits is not subject to liquidation of exchange for another benefit.

(g)The Company makes no warranty regarding the tax treatment to the Executive of payments provided for under this Agreement, including the tax treatment of such payments that may be subject to Section 409A. The Executive will be responsible for paying all federal, state, and local income and employment taxes that may be due on such payment, provided that the Company will be responsible for any withholding obligations under applicable law. The Company will not be liable to the Executive if any payment or benefit which is to be provided pursuant to this Agreement and which is considered deferred compensation subject to Code Section 409A otherwise fails to comply with, or be exempt from, the requirements of Code Section 409A.

6.Mandatory Reduction of Payments in Certain Events. Anything in this Agreement to the contrary notwithstanding, in the event it shall be determined that any payment or distribution by the Company to or for the benefit of Executive (whether paid or payable or distributed or distributable pursuant to the terms of this Agreement or otherwise) (a “Payment”) would be subject to the excise tax (the “Excise Tax”) imposed by Section 4999 of the Code, then, prior to the making of any Payment to Executive, a calculation shall be made comparing (i) the net benefit to Executive of the Payment after payment of the Excise Tax to (ii) the net benefit to Executive if the Payment had been limited to the extent necessary to avoid being subject to the Excise Tax. If the amount calculated under (i) above is less than the amount calculated under (ii) above, then the Payment shall be limited to the extent necessary to avoid being subject to the Excise Tax (the “Reduced Amount”). In that event, cash payments shall be modified or reduced first from the latest amounts to be paid and then any other benefits. The determination of whether an Excise Tax would be imposed, the amount of such Excise Tax, and the calculation of the amounts referred to in clauses (i) and (ii) of the foregoing sentence shall be made by an independent accounting firm selected by Company and reasonably acceptable to the Executive, at the Company’s expense (the “Accounting Firm”), and the Accounting Firm shall provide detailed supporting calculations. Any determination by the Accounting Firm shall be binding upon the Company and the Executive. As a result of the uncertainty in the application of Section 4999 of the Code at the time of the initial determination by the Accounting Firm hereunder, it is possible that Payments which Executive was entitled to, but did not receive pursuant to this Section 5.6 could have been made without the imposition

of the Excise Tax (“Underpayment”). In such event, the Accounting Firm shall determine the amount of the Underpayment that has occurred and any such Underpayment shall be promptly paid by the Company to or for the benefit of the Executive.

7.Governing Law. Notwithstanding the place where this Agreement may be executed by any of the parties hereto, the parties expressly agree that all of the terms and provisions hereof shall be construed in accordance with and governed by the laws of the State of Missouri, or, to the extent applicable the laws of the United States of America, in each case without giving effect to the principles of choice or conflicts of laws thereof. Each of the parties hereto consents and agrees to the exclusive personal jurisdiction of any state or federal court sitting in the State of Missouri, and waives any objection based on venue or forum non conveniens with respect to any action instituted therein, and agrees that any dispute concerning the conduct of any party in connection with this Agreement shall be heard only in the courts described above.

8.Binding Arbitration.

(a)All disputes arising under this Agreement or arising out of or relating to the Executive’s employment relationship with the Company shall be submitted to final and binding arbitration. Arbitration of such matters shall proceed consistent with the Employment Arbitration Rules and Mediation Procedures as established by the American Arbitration Association (“AAA”). Venue for any arbitration shall be St. Louis, Missouri or any other location mutually agreed upon by the Executive and the Company.

(b)The arbitration shall be conducted using the Expedited Procedures of the AAA Rules, regardless of the amount in dispute.

(c)The disputing parties shall agree on an arbitrator qualified to conduct AAA arbitration. If the disputing parties cannot agree on the choice of arbitrator, then each party shall choose one independent arbitrator. The two arbitrators so chosen shall jointly select a third arbitrator, who shall conduct the arbitration.

(d)All disputes relating to this Agreement shall be governed by the laws of the State of Missouri, and the arbitrator shall apply such law without regard to the principles of choice or conflicts of laws thereof.

(e)All aspects of the arbitration shall be treated as confidential.

(f)The Company and the Executive shall each pay 50% of the arbitrator’s fees and costs. Each party shall pay its own deposition, witness, expert, and attorneys’ fees and other expenses to the same extent as if the matter were being heard in court. However, if any party prevails on a statutory claim that affords the prevailing party attorneys’ fees and costs, or if there is a written agreement providing for attorneys’ fees and costs to be awarded to the prevailing party, the arbitrator may award reasonable attorneys’ fees in accordance with the applicable statute or written agreement. The arbitrator shall resolve any dispute as to the reasonableness of any fees or costs awarded under this paragraph.

(g)The decision of the arbitrator shall be final, and the parties agree to entry of such decision as judgments in all courts of appropriate jurisdiction.

(h)Notwithstanding the foregoing, this Section 5.8 shall not preclude either party from pursuing a court action for the sole purpose of obtaining a temporary restraining order or a preliminary injunction in circumstances in which such relief is appropriate, including, without limitation, relief sought under Section 4 of this Agreement; provided that any other relief shall be pursued through an arbitration proceeding pursuant to this Section 5.8.

9.Amendments. This Agreement shall not be modified or amended except by a writing signed by all of the parties.

10.Binding Effect. This Agreement shall be binding upon and shall inure to the benefit of the successors and assigns of each party hereto.

11.Assignment.

(a)This Agreement and all of the Executive’s rights and obligations hereunder are personal to the Executive and may not be transferred or assigned by him at any time, except that any assets accruing to the Executive in connection with this Agreement shall accrue to the benefit of the Executive’s heirs, executors, administrators, successors, permitted assigns, trustees, and legal representatives.

(b)The Company may assign its rights under this Agreement to any entity that assumes the Company’s obligations hereunder in connection with a merger, consolidation or sale or transfer of all or substantially all of the Company’s assets to such entity; provided further, that the Company will require any successor to the Company in the case of a merger, consolidation or sale or transfer of all or substantially all of the assets of Avadel plc or the Company to assume this Agreement.

12.Waiver. Any of the terms or conditions of this Agreement may be waived at any time by the party or parties entitled to the benefit thereof, but only by a writing signed by the party or parties waiving such terms or conditions. No waiver of any provision of this Agreement or of any right or benefit arising hereunder shall be deemed to constitute or shall constitute a waiver of any other provision of this Agreement (whether or not similar), nor shall any such waiver constitute a continuing waiver, unless otherwise expressly so provided in writing.

13.Counterparts. This Agreement may be executed in counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. Signatures on this Agreement may be conveyed by facsimile or other electronic transmission and shall be binding upon the parties so transmitting their signatures. Counterparts with original signatures shall be provided to the other parties following the applicable facsimile or other electronic transmission; provided, that failure to provide the original counterpart shall have no effect on the validity or the binding nature of this Agreement.

IN WITNESS WHEREOF, the parties hereto have executed this Employment Agreement as of the date and year first above written.
