1.5           The Investor agrees and covenants that all amounts the Investor may be entitled to receive in respect of proceeds received by the Company pursuant to its past and future transactions with Adapt Pharma Operations Limited and its affiliates (“Adapt”) with respect to the Product, shall be the responsibility and obligation solely of the Company or its successor. The Investor agrees and covenants, for the benefit of the Company and Adapt, Adapt’s successors, assigns and sublicensees and each of their respective shareholders, directors, officers and employees (the “Adapt Parties”), that it shall under no circumstances seek payment or other compensation for any such amount directly from any Adapt Party or assert any claim against any Adapt Party in relation to the Company’s past and future transactions with Adapt with respect to the Product. The Company and the Investor agree that the Adapt Parties are express third party beneficiaries of the Investor’s covenants contained herein and may enforce the provisions hereof.

2.           Net Profit Audits, Updates, Distributions and Other Transactions.

2.1           The Company shall provide the Investor with an annual audit of Net Profits (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 Investor 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 Investor with a written or electronic statement of the estimated Net Profit represented by the Interest and represented by the Additional Interest, if there is an Additional Interest.

2.3           After the end of each of the first three quarters of the calendar year, the Company shall distribute to the Investor eighty percent (80%) of such calendar quarter’s Net Profits represented by the Interest and the Additional Interest, if there is an Additional 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 Investor the Net Profits represented by the Interest and the Additional Interest, if there is an Additional Interest, for the fourth quarter of the calendar year. In the event that the Audit for such calendar year determines the Net Profits represented by the Interest and the Additional Interest, if there is an Additional Interest, for the first three quarters of the calendar year (the “Audited NP”) to be greater than the estimated Net Profits represented by the Interest and the Additional Interest, if there is an Additional Interest, actually paid to the Investor for the first three calendar quarters (the “Estimated NP”), then the Company shall distribute to the Investor 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 Investor shall receive 75/100ths of one percent (0.75%) 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 Investor shall receive 75/100ths of one percent (0.75%) of such amount after the deduction of all expenses and costs related to such sale. If there is an Additional Interest, then in the event that the Product is sold by the Company, then the Investor shall receive one and one half of one percent (1.50%) 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. If there is an Additional Interest, then 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 Investor shall receive one and one half of one percent (1.50%) 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 Investor.
