Scope of Services

For

Consulting

This Scope of Services is subject to the terms and conditions of the Consulting Agreement by and between TFF Pharmaceuticals, Inc. (“Company”), and James Brian Windsor (“Consultant”), dated to be effective as of January 24, 2018 (the “Agreement”), and shall be attached to and incorporated into such Agreement as Exhibit A. This Scope of Services does not supersede the Agreement, which defines the terms and conditions of the business arrangement between Company and Consultant.

Compensation will be $37,500 per quarter for providing services as acting Chief Science Officer and Secretary. Consultant shall be paid this amount for the duration of the Initial Compensation Period. For purposes of this Scope of Services, the “Initial Compensation Period” shall begin January 7, 2018 through the date the Company has completed its initial round of financing (such initial round must be for a minimum of $500,000, herein the “Initial Round Closing”), has hired a replacement Chief Science Officer, and such Chief Science Officer has begun full-time employment. Notwithstanding the foregoing, in no event shall the Initial Compensation Period be less than six months. Consultant is not expecting a bonus nor any need to be provided with health benefits. Also, Consultant will not be considered an employee of the Company. Consultant will not invoice the Company for the Services until after the Initial Round Closing.

Following the Initial Compensation Period, Consultant’s compensation shall change to $25,000 per quarter, with such compensation period lasting until the Company has completed an initial public offering (IPO) or 12 months following the closing of the Initial Compensation Period, whichever is later. This period shall be referred to herein as the “Middle Compensation Period.” Following the Middle Compensation Period, Consultant will continue to provide services for $12,500 per quarter, for a minimum of one year.

Consultant will be granted an option to purchase 20,000 shares of the Company’s common stock, equal to 0.5% of the Company’s common stock. The option strike price will be determined pursuant to a valuation of the Company’s common stock performed by an independent third party valuation specialist for purposes of compliance with Internal Revenue Code Section 409A after the Initial Round Closing. Subsequent to the IPO, Consultant will receive additional grants to ensure that Consultant maintains at least 0.5% ownership of the Company. Any subsequent sale of shares of the Company after the IPO will result in dilution of Consultant’s equity position with the Company’s other stockholders

Prior to the Initial Round Closing, Lung Therapeutics, Inc. (LTI), the parent of the Company, will provide D&O insurance coverage for Consultant and all Board members and Officers of the Company of no less than $5 million for which the Company will reimburse LTI immediately following the Initial Round Closing.

LTI will reimburse Consultant for any travel that occurs related to the Company prior to the Initial Round Closing and LTI will be subsequently reimbursed after the funds from the initial financing have been received by the Company.
