On June 19, 2018, PetroTerra Corp. (the “ Company ”) entered into a securities purchase agreement (the “ Purchase Agreement ”), whereby it issued to an institutional investor (the “ Lender ”) a senior secured convertible note in the aggregate principal amount of $2,497,502.50 (the “ Note ”), for an aggregate purchase price of $1,665,000.00. The principal due under the Note accrues interest at a rate of 10% per annum. Interest is payable monthly over the term of the Note in cash or common stock of the Company, at the Lender’s discretion. The principal amount of the Note amortizes beginning on the sixth month following the original issue date of the Note, until the maturity date. All principal and accrued interest under the Note is convertible into shares of the Company’s common stock, par value $0.001 (“ Common Stock ”), at a conversion price equal to the lower of $0.006 and 65% of the lowest traded price during the fifteen trading days immediately prior to the conversion date. The Note includes anti-dilution protection, as well as customary events of default, including non-payment of the principal or accrued interest due on the Note. Upon an event of default, all obligations under the Note will become immediately due and payable and the Company will be required to make certain payments to the Lender. In addition, the Lender was issued a warrant, with a term of two years, to purchase up to 4.75% of the fully-diluted outstanding Common Stock of the Company, for an aggregate purchase price of $100.00 (the “ Warrant ”).

The Lender was granted a right of first refusal on future financing transactions of the Company while the Note remains outstanding, plus an additional three months thereafter. In connection with the issuance of the Note, the Company entered into a security agreement with the Lender (the “ Security Agreement ”) pursuant to which the Company agreed that obligations under the Note and related documents will be secured by all of the assets of the Company. In addition, all of the Company’s subsidiaries are guarantors of the Company’s obligations to the Lender pursuant to the Note and have granted a similar security interest over substantially all of their assets. The proceeds of the Note were used to acquire 100% of the membership interests of Prime EFS LLC, a New Jersey limited liability company (“ Prime ”).

On June 18, 2018, the Company entered into a Stock Purchase Agreement (the “ Stock Agreement ”) with all of the holders of the membership interests of Prime, whereby they agreed to sell, and the Company agreed to purchase, all of the issued and outstanding membership interests of Prime. The purchase price paid by the Company is an aggregate of $1,000,000.00 in cash, 1,500,000 shares of the Company’s Common Stock, and shares of a newly designated series of preferred stock of the Company intended to true-up the value of the Common Stock issued to the Prime sellers such that the aggregate value of the securities they receive equals the trailing twelve-month gross profit of the Company, to be calculated as of December 31, 2018. In addition, the Company is obligated to provide Prime with a certain amount of working capital both at closing and over the next six months.
