The closing of the sale and purchase of the Units (the “ Closing ”), shall take place electronically upon the satisfaction (such date, the “ Closing Date ”) of the conditions to set forth in Section 5 hereof. Subject to the foregoing, at the Closing, the Company shall issue, on a pro rata basis to the Purchasers, up to $5,500,000 of Units to be delivered to the Escrow Agent in accordance with the terms of the Escrow Agreement (as defined below). In the event that a Closing for at least $3,500,000 has not occurred by August 30, 2017, this Agreement will terminate and the Company shall cause any of the Purchase Price that has been funded into the Escrow Account (as defined below) to be returned to the Purchasers. Provided that a Closing for at least $3,500,000 has occurred, the Company may hold additional closings, each a “Closing”, at which time additional Units may be sold until $5,500,000 is raised. The Escrow Agreement which is attached as Exhibit E hereto contains provisions governing the release of the escrowed funds and Units from the Escrow Account following Closing. Until released to the Company in accordance with the Escrow Agreement, the Purchasers will have a first security interest in the funds in the Escrow Account which shall be perfected by the filing of a UCC-1financial statement which the Company hereby consents to.
