of

Inmune Bio Inc.

This subscription agreement (this “Subscription”) is dated          , 2018, by and between the investor identified on the signature page hereto (the “Investor”) and Inmune Bio Inc., a Nevada corporation (the “Company”). The parties agree as follows:

1. Subscription

Investor agrees to buy and the Company agrees to sell and issue to Investor such number of Company’s common stock (the “Shares”), par value $0.001 per share, as set forth on the signature page hereto, for an aggregate purchase price (the “Purchase Price”) equal to the product of (x) the aggregate number of Shares the Investor has agreed to purchase and (y) the Purchase Price per Share as set forth on the signature page hereto.

The Shares are being offered pursuant to a registration statement on Form S-1, File No. 333-27122 (the “Registration Statement”). The Registration Statement was declared effective by the Securities and Exchange Commission (the “Commission”) prior to issuance of any Shares and acceptance of Investor’s subscription. The prospectus (the “Prospectus”) which forms a part of the Registration Statement, however, is subject to change. A final prospectus and/or prospectus supplement will be delivered to the Investor as required by law.

The Shares are being offered by Univest Securities, LLC (the “Placement Agent”) as Placement Agent on a “best efforts, minimum/maximum” basis pursuant to an underwriting agreement (the “Placement Agent Agreement”). The completion of the purchase and sale of the Shares (the “Closing”) shall take place at a place and time (the “Closing Date”) to be specified by the Company and Placement Agents in accordance with Rule 15c6-1 promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Upon satisfaction or waiver of all the conditions to closing set forth in the Placement Agent Agreement and the Registration Statement declared effective by the Commission, at the Closing (i) the Purchase Price deposited by the Investor subsequent to the declaration of effectiveness of the Registration Statement by wire transfer or ACH transfer of immediately available funds to the Company’s escrow accounts shall be released to the Company, and (ii) the Company shall cause the Shares to be delivered to the Investor (A) through the facilities of The Depository Trust Company’s DWAC system in accordance with the instructions set forth on the signature page attached hereto under the heading “DWAC Instructions,” or (B) if requested by the Investor on the signature page hereto or if the Company is unable to make the delivery through the facilities of The Depository Trust Company’s DWAC system, through the DRS or book-entry delivery of Shares on the books and records of the transfer agent. If delivery is made by book entry on the books and records of the transfer agent, the Company shall send written confirmation of such delivery to the Investor at the address indicated on the Signature Page hereof.

The Placement Agent and any participating broker dealers (the “Members”) shall confirm, via the Placement Agent Agreement, selected dealer agreement or master selected dealer agreement, as applicable, that it will comply with Exchange Act Rule 15c2-4. Payments may only be made by wire transfer or electronic deposit, and no payments may be made by check. With regards to monies being wired or sent via ACH transfer from an investor’s bank account, the Members shall request the investors send their wires or ACH transfers by the business day immediately following the receipt of a completed subscription document. In regards to monies being sent from an investor’s account held at the participating broker, the funds will be “promptly transmitted” to the escrow agent following the receipt of a completed subscription document and completed instructions by the investor to send funds to the escrow accounts. Absent unusual circumstances, funds in customer accounts will be transmitted by noon of the next business day. In the event that the offering does not close for any reason prior to the termination date set forth in the Registration Statement, all funds deposited in the escrow accounts will be returned to investors promptly in accordance with the terms of the escrow agreements and applicable law.

2. Subscription Process.

To purchase our Shares in this offering, investors must complete and sign a subscription agreement. Investors will be required to pay for their Shares by wire or ACH transfer for the full purchase price of the Shares. China Merchants Bank New York Branch shall serve as escrow agent for any payments made via wire or ACH transfer.

Subscriptions will be effective only upon our acceptance of the subscriptions, and we reserve the right to reject any subscriptions in whole or in part. In compliance with Rule 15c2-4 under the Exchange Act, we and the Placement Agent will instruct investors to deliver all monies in the form of wire transfers or ACH transfers to the escrow agent. Upon the escrow agent’s receipt of such monies, they shall be credited to the escrow accounts. Pursuant to escrow agreements among us, Placement Agent and China Merchants Bank New York, as escrow agent, the funds received in payment for the Shares purchased in this offering will be wired to a non-interest bearing escrow account at China Merchants Bank New York Branch, and held until the escrow agent determines that the amount in the escrow account is equal to at least the minimum amount required to close this offering. Upon confirmation of receipt of the requested minimum subscription amount, the escrow agent will release the funds in accordance with the written instructions provided by us and Placement Agent, indicating the date on which the Shares purchased in this offering are to be delivered to the investors and the date the net proceeds are to be delivered to us.
