AMENDED AND RESTATED CONSULTING AGREEMENT

This Amended and Restated Consulting Agreement (the “Agreement”) is entered into on October 25, 2016 (the “Execution Date”), and made effective as of July 17, 2013 (the “Effective Date”), by and between LYL Holdings Inc., a corporation and successor in interest to this Agreement (the “Consultant”), and Opiant Pharmaceuticals, Inc., a Nevada corporation (the “Company”).

WHEREAS, on the Effective Date, the Company entered into that certain consulting agreement (the “Initial Consulting Agreement”), as amended by a subsequent letter agreement dated October 15, 2014, by and between the Company and two third party consultants (the “Letter Agreement” and, together with the Initial Consulting Agreement, the “Initial Agreement”), whereby the third party consultants, using their expertise in the biopharmaceutical space, provided certain consulting and advisory services to the Company during the period commencing on the Effective Date through the three (3) year anniversary of the Effective Date (the “Services”);

WHEREAS, the Company has developed a treatment to reverse opioid overdoses (known as NARCAN® (naloxone hydrochloride) Nasal Spray (the “Product”);

WHEREAS, pursuant to the Initial Agreement, the Company, in exchange for the Services provided by the third party consultants, assigned the third party consultants the right to receive a certain amount of the financial return produced by the Product; and

WHEREAS, the third party consultants have since assigned their rights and obligations under the Initial Agreement to the Consultant and the Consultant and the Company now desire to amend and restate the Initial Agreement to (i) reflect the occurrence of events since the Effective Date, (ii) incorporate the terms of the Letter Agreement and (iii) add the Consultant, and remove the third party consultants, as a party to this Agreement.

NOW, THEREFORE, with reference to the foregoing facts, the Company and the Consultant agree as follows:

1.1         In exchange for the Services provided by the third party consultants, the Consultant shall receive the right to receive, pro rata, five percent (5%) of the Net Profit generated from the Product in perpetuity from the Effective Date (the “Interest”). “Net Profit” shall be defined as any pre-tax revenue received by the Company that was derived from the sale of the Product less any and all expenses incurred by and payments made by the Company in connection with the Product, including but not limited to an allocation of Company overhead based on the proportionate time, expenses and resources devoted by the Company to Product-related activities, which allocation shall be determined in good faith by the Company.

2.1         The Company shall provide the Consultant with an annual audit of Net Profit (the “Audit”), which Audit shall be completed after the end of each calendar year.  Notwithstanding the foregoing, this Paragraph 2.1 shall not be applicable until the Product generates Net Profit.

2.2         After the end of each quarter of the calendar year, the Company shall provide the Consultant with a written or electronic update with respect to the status of the Product. If the Product generates Net Profit, then the Company shall also provide the Consultant with a written or electronic statement of the estimated Net Profit represented by the Interest.

2.3         After the end of each of the first three quarters of the calendar year, the Company shall distribute to the Consultant eighty percent (80%) of such calendar quarter’s Net Profit represented by the Interest, which amount shall be estimated in good faith by the Company. Upon the completion of the Audit for such calendar year, the Company shall distribute to the Consultant the Net Profit represented by the Interest for the fourth quarter of the calendar year. In the event that the Audit for such calendar year determines the Net Profit represented by the Interest for the first three quarters of the calendar year (the “Audited NP”) to be greater than the estimated Net Profit represented by the Interest actually paid to the Consultant for the first three calendar quarters (the “Estimated NP”), then the Company shall distribute to the Consultant the difference between the Audited NP and the Estimated NP. In the event that the Audit for such calendar year determines the Audited NP to be less than the Estimated NP, then the Company shall deduct the difference between the Estimated NP and the Audited NP from the distribution for the fourth quarter of such calendar year and, if required, each following distribution until such amount is fully deducted.

2.4         In the event that the Product is sold by the Company, then the Consultant shall receive five percent (5%) of the net proceeds of such sale, pro rata, and in the form of such net proceeds, after the deduction of all expenses and costs related to such sale. In the event that the Company is sold, then the Company shall engage an independent financial or accounting firm to determine the fair value of the Company which is directly attributable to the Product and the Consultant shall receive five percent (5%) of such amount after the deduction of all expenses and costs related to such sale. All other material transactions involving the Product not addressed herein shall be addressed in good faith by the Company and the Consultant.

The Company represents and warrants to the Consultant that:

3.1         The Company is a public company duly organized, validly existing and in good standing under the laws of Nevada and has all requisite power and authority to own, lease and operate its properties and assets and to carry on its business as now being conducted and as proposed to be conducted.

3.2         This Agreement has been duly executed and delivered by the Company and constitutes a valid and legally binding obligation of the Company enforceable against the Company in accordance with its terms, subject to the effect of bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance and other similar laws relating to or affecting creditors' rights generally, or the availability of equitable remedies.
