Item 1.01 Entry into a Material Definitive Agreement.

On August 11, 2017, an indirect wholly owned subsidiary (the "Avadel Licensee") of Avadel Pharmaceuticals plc (the "Company") entered into an exclusive right of negotiation agreement (the "Exclusivity Agreement") with Serenity Pharmaceuticals, LLC ("Serenity"). Under the Exclusivity Agreement, Serenity agreed to negotiate exclusively with the Avadel Licensee regarding the proposed transaction described below (the "Proposed Transaction") until the earliest to occur of (i) 11:59 p.m. (U.S. East Coast Time) on September 7, 2017, or, under certain circumstance as described below, 11:59 p.m. (U.S. East Coast Time) on September 14, 2017 (such date, the "Expiration Date"), (ii) receipt by either party of a written notice from the other party that such other party is terminating negotiations with respect to the proposed Exclusive License Agreement (as defined below), or (iii) the date the proposed Exclusive License Agreement is executed.

If the Avadel Licensee continues to engage with Serenity in good faith negotiations relating to the Proposed Transaction and circumstances beyond the control of the parties make it unlikely that the parties will execute and deliver the Exclusive License Agreement by 11:59 p.m. on September 7, 2017, then, if at such time it is reasonable to assume that continuation of such negotiations will result in the execution and delivery by the parties of the Exclusive License Agreement by 11:59 p.m. on September 14, 2017, then the Expiration Date shall be extended to that later date.

Under the Proposed Transaction, Serenity would grant to the Avadel Licensee an exclusive license, under certain rights of Serenity in and to certain intellectual property (the "IP Rights"), to develop and commercialize the drug desmopressin acetate (the "Drug") in the United States, Canada, and their respective territories and possessions (the "Territory") for the treatment of certain medical conditions characterized by abnormalities or disorders in voiding and other urinary functions of a subject to control urination (the "Field") pursuant to a proposed exclusive license and assignment agreement in substantial form and substance as set forth on an exhibit to the Exclusivity Agreement (the "Exclusive License Agreement"). In addition, under the Exclusive License Agreement, Serenity would assign to the Avadel Licensee the New Drug Application for the Drug approved by the U.S. Food and Drug Administration (the "NDA"), and certain supply agreements relating to the Drug (the "Supply Agreements").

Either Serenity or the Avadel Licensee may terminate the Exclusivity Agreement at any time prior to the Expiration Date by notice to the other party; however, if Serenity receives an unsolicited offer for an alternative transaction on terms that are superior to the Proposed Transaction, Serenity will provide Avadel with the opportunity to match such offer within five (5) Business Days of being notified by Serenity of such alternative transaction.

Under the Exclusivity Agreement, the Avadel Licensee will deposit Five Million U.S. Dollars (US$5,000,000) (the "Escrow Amount") with an escrow agent, to be held and transferred by the escrow agent as follows:

(a) If the parties execute and deliver the Exclusive License Agreement prior to the Expiration Date, the Escrow Amount will be transferred to Serenity in partial satisfaction of any upfront payment to be made by the Avadel Licensee to Serenity under the Exclusive License Agreement.

(b) If the Exclusivity Agreement is terminated by the Avadel Licensee without Cause (as defined below with respect to such termination by the Avadel Licensee) or by Serenity with Cause (as defined below with respect to such termination by Serenity), or the parties fail to execute and deliver the Exclusive License Agreement by the Expiration Date (notwithstanding Serenity's good faith efforts to do so and provided that the Exclusive License Agreement is in substantial form and substance as set forth on the exhibit to the Exclusivity Agreement), then the Escrow Amount will be transferred to Serenity, and the Avadel Licensee will also pay to Serenity an additional amount of Five Million U.S. Dollars (US$5,000,000). The sum of the Escrow Amount and the additional $5,000,000 payment to be transferred by the Avadel Licensee to Serenity (i.e., an aggregate of $10,000,000) will be consideration, in part, to Serenity for granting the Avadel Licensee the exclusive negotiating rights under the Exclusivity Agreement.

(c) If the Exclusivity Agreement is terminated by the Avadel Licensee with Cause or by Serenity without Cause, then the full amount of the Escrow Amount will be returned to the Avadel Licensee; and in addition, if Serenity terminates the Exclusivity Agreement without Cause, then Serenity will pay to the Avadel Licensee the additional amount of Ten Million U.S. Dollars (US$10,000,000), as consideration for the Avadel Licensee's time, effort, and resources to evaluate, pursue, and negotiate the Proposed Transaction.

For purposes of the Exclusivity Agreement, "Cause" means:

(i) with respect to termination by the Avadel Licensee with Cause, (a) the receipt by the Avadel Licensee of an opinion of counsel, which counsel shall be reasonably acceptable to Serenity, that the Avadel Licensee will not have freedom to commercialize the Drug in the United States as contemplated by the draft Exclusive License Agreement because of intellectual property rights held by third parties, (b) a change affecting the IP Rights, the NDA, or the Supply Agreements that would have a material and adverse effect on the contemplated commercialization by the Avadel Licensee of the Drug in the United States, (c) a material misstatement or omission by Serenity in its disclosures to the Avadel Licensee about the IP Rights, the NDA, or the Supply Agreements, (d) the bankruptcy or insolvency of Serenity, (e) the breach of Serenity's covenant to negotiate exclusively with the Avadel Licensee, or (f) Serenity does not agree to execute the Exclusive License Agreement in substantial form and substance as set forth on the exhibit to the Exclusivity Agreement by the Expiration Date (notwithstanding the Avadel Licensee's good faith effort to do so); and

(ii) with respect to termination by Serenity with Cause, (a) a material adverse change in the business, operations, or financial condition of Avadel, (b) a material misstatement or omission by the Avadel Licensee in its disclosures to Serenity about the Avadel Licensee or the Avadel Licensee's intentions with respect to the Proposed Transaction, that has a material and adverse effect on the Proposed Transaction or (c) the bankruptcy or insolvency of the Avadel Licensee.

The form of Exclusive License Agreement attached as an exhibit to the Exclusivity Agreement provides that:

Serenity will grant the Avadel Licensee an exclusive license to commercialize, develop and manufacture the Drug for use in the Field throughout the Territory. The Avadel Licensee may sublicense the licensed rights in Canada immediately and in the U.S. beginning two years after the effective date of the license, in all cases subject to Serenity's prior written consent which may not be unreasonably withheld, conditioned, or delayed.

The Avadel Licensee will use its commercially reasonable efforts at all times to commercialize the rights licensed to it under the Exclusive License Agreement. The Avadel Licensee is responsible for the costs associated with all regulatory activities, including development activities undertaken to support obtaining or maintaining regulatory approvals. Within 120 days of the effective date of the Exclusive License Agreement, the Avadel Licensee will provide Serenity with a plan with respect to the commercialization of the Drug in the Field in the Territory.

Within 180 days following the effective date of the Exclusive License Agreement, the Avadel Licensee will notify Serenity of its decision to undertake development of the Drug for the "Nocturia Indication" (i.e., nocturia due to nocturnal polyuria) in Canada and the PNE Indication (i.e., bed-wetting) in the United States and/or Canada. Serenity will have the right to develop and commercialize the Drug for the PNE Indication in the Territory and the Nocturia Indication in Canada if the Avadel Licensee decides not to undertake such development.

·	The Avadel Licensee will be required to pay Serenity an initial payment upon execution of the Exclusive License Agreement, and royalty payments based on net sales of the products in the Territory.

The Avadel Licensee will indemnify Serenity for losses arising out of its (a) gross negligence or willful misconduct by the Avadel Licensee in connection with its performance or obligations arising under the Exclusive License Agreement, (b) any material breach of obligations, representations, warranties or covenants by the Avadel Licensee under the Exclusive License Agreement, (c) development and commercialization activities in respect of the Drug undertaken by the Avadel Licensee, (d) failure by the Avadel Licensee to comply with applicable laws, and (e) any allegation that personal injury or death, or damage to property was caused by a manufacturing defect in the Drug manufactured by the Avadel Licensee or its third-party suppliers.

Serenity will indemnify the Avadel Licensee for losses arising out of its (a) gross negligence or willful misconduct by Serenity in connection with its performance or obligations arising under the Exclusive License Agreement, (b) any material breach of obligations, representations, warranties or covenants by Serenity under the Exclusive License Agreement, (c) development and commercialization activities in respect of the Drug undertaken by Serenity, and (d) failure by Serenity to comply with applicable laws.

The Exclusive License Agreement includes various other representations, warranties, covenants, indemnities and other provisions customary for transactions of this nature.

The foregoing summary of the Exclusivity Agreement, including the description of the form of Exclusive License Agreement attached thereto as an exhibit, does not purport to be complete and is subject to, and qualified in its entirety by, the Exclusivity Agreement, and the form of Exclusive License Agreement attached thereto as an exhibit. The Avadel Licensee intends to submit a FOIA Confidential Treatment Request with the Securities and Exchange Commission pursuant to Rule 24b-2 under the Securities Exchange Act of 1934, as amended, for certain portions of the form of Exclusive License Agreement attached as an exhibit to the Exclusivity Agreement. The Exclusivity Agreement, with the form of Exclusive License Agreement attached as an exhibit and subject to confidential treatment, will be filed as an exhibit to the Company's Quarterly Report on Form 10-Q for the quarter ending September 30, 2017.
