Interest will accrue at a simple rate of 12% per annum. Unless earlier converted into Conversion Shares (as defined below), the principal and accrued interest of this Note will be due and payable by the Company at any time on or after November 22, 2019 (the “Maturity Date”) at the Company's election or upon demand by the Holder. Capitalized terms not otherwise defined in this Note will have the meanings set forth in Section 3.1.

Background

WHEREAS, Paramount Trading, Ltd., a company owned by the Holder (“Paramount”), previously extended to the Company loans (the “Loans”) in the aggregate principal amount of $276,825.03 with interest accruing at 5% per annum (the “Loan Balance”); and

WHEREAS, Paramount was dissolved in September 2016; and

WHEREAS, the Company and the Holder desires to amend and restate the terms of the Loans by entering into this Note, which reflects the Loan Balance as of the date hereof, which as a result of Paramount’s liquidation, are owed to the Holder.

NOW, THEREFORE, for good and valuable consideration, the receipt, sufficiency and adequacy of which are hereby acknowledged, intending to be legally bound, the parties hereby agree as follows:

1.       Payment. All payments will be made in lawful money of the United States of America, in immediately available funds, by such method and at such place as the Holder may from time to time designate in writing to the Company. Payment of principal and interest will be credited first to accrued interest due and payable, with any remainder applied to principal. Prepayment of principal, together with accrued interest, may be made at any time without premium or penalty (subject to the provisions of Section 3 hereof).

2.       Security. This Note is a general unsecured obligation of the Company.

3.       Conversion. This Note will be convertible into Equity Securities pursuant to the following terms.

3.1       Definitions.

(a)       “Common Stock” means the Company's common stock, par value US $0.0001 per share.

(b)       “Conversion Shares” (for purposes of determining the type of Equity Securities issuable upon conversion of this Note) means:

(i)       with respect to a conversion pursuant to Section 3.2, shares of the Equity Securities issued in the Next Equity Financing;

(ii)      with respect to a conversion pursuant to Section 3.3, shares of the Equity Securities issued in the Corporate Transaction; and

(iii)     with respect to a conversion pursuant to Section 3.4, shares of Common Stock.

(c)       “Conversion Price” means (rounded to the nearest 1/100th of one cent):

(i)       with respect to a conversion pursuant to Section 3.2, the price per security issued in a Next Equity Financing;

(ii)      with respect to a conversion pursuant to Section 3.3, a conversion price that is equal to the enterprise value of the Company, as established by the consideration payable in the Corporate Transaction, so as to permit the Holder to receive the cash, securities or other property to which the Holder would be entitled in the Corporate Transaction on account of the Holder’s ownership of the Common Stock; and

(iii)     with respect to a conversion pursuant to Section 3.4, the quotient resulting from dividing (x) the Valuation Cap by (y) the Fully Diluted Capitalization immediately prior to such conversion.

(d)       “Corporate Transaction” means:

(i)       the closing of the sale, transfer or other disposition, in a single transaction or series of related transactions, of all or substantially all of the Company's assets;

(ii)       the consummation of a merger or consolidation of the Company with or into another entity (except a merger or consolidation in which the holders of capital stock of the Company immediately prior to such merger or consolidation continue to hold a majority of the outstanding voting securities of the capital stock of the Company or the surviving or acquiring entity immediately following the consummation of such transaction); or

(iii)      the closing of the transfer (whether by merger, consolidation or otherwise), in a single transaction or series of related transactions, to a “person” or “group” (within the meaning of Section 13(d) and Section 14(d) of the Exchange Act), of the Company's capital stock if, after such closing, such person or group would become the “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act) of more than 50% of the outstanding voting securities of the Company (or the surviving or acquiring entity).

For the avoidance of doubt, a transaction will not constitute a “Corporate Transaction” if its sole purpose is to change the state of the Company's incorporation or to create a holding company that will be owned in substantially the same proportions by the persons who held the Company's securities immediately prior to such transaction. Notwithstanding the foregoing, the sale of Equity Securities in a bona fide financing transaction will not be deemed a “Corporate Transaction.”

(e)       “Equity Securities” means (i) Common Stock; (ii) any securities conferring the right to purchase Common Stock; or (iii) any securities directly or indirectly convertible into, or exchangeable for (with or without additional consideration) Common Stock. Notwithstanding the foregoing, the following will not be considered “Equity Securities”: (A) any security granted, issued or sold by the Company to any director, officer, employee, consultant or adviser of the Company for the primary purpose of soliciting or retaining their services; (B) any convertible promissory notes (including this Note) issued by the Company; and (C) any SAFEs that have been issued by the Company.

(f)       “Exchange Act” means the Securities Exchange Act of 1934, as amended.

(g)       “Fully Diluted Capitalization” means the number of issued and outstanding shares of the Company's capital stock, assuming the conversion or exercise of all of the Company's outstanding convertible or exercisable securities, including shares of convertible Preferred Stock and all outstanding vested or unvested options or warrants to purchase the Company's capital stock. Notwithstanding the foregoing, “Fully Diluted Capitalization” excludes: (A) any convertible promissory notes (including this Note) issued by the Company; (B) any SAFEs (as defined below) issued by the Company; and (C) any Equity Securities that are issuable upon conversion of any outstanding convertible promissory notes or SAFEs.

(h)       “Next Equity Financing” means any subsequent sales by the Company of its Equity Securities, in one or a series of related transactions, following the date of issuance of this Note from which the Company receives aggregate gross proceeds of not less than US$7,500,000.00 (excluding, for the avoidance of doubt, the aggregate principal amount of this Note).

(i)       “Preferred Stock” means all series of the Company's preferred stock, whether now existing or hereafter created.

(j)       “SAFE” means any simple agreement for future equity (or other similar agreement) which is issued by the Company for bona fide financing purposes and which may convert into the Company's capital stock in accordance with its terms.

(k)       “Securities Act” means the Securities Act of 1933, as amended.

(l)       “Valuation Cap” means US$20,000,000.

3.2       Next Equity Financing Conversion. In the event that, at any time while this Note shall remain outstanding, a Next Equity Financing shall occur, the Holder, at its sole option, may elect in writing to convert the principal balance and unpaid accrued interest on this Note upon the closing of the Next Equity Financing. Notwithstanding the foregoing, the Company may, at its option, pay any unpaid accrued interest on this Note in cash at the time of conversion. The number of Conversion Shares the Company issues upon such conversion will equal the quotient (rounded down to the nearest whole share) obtained by dividing (x) the outstanding principal balance and unpaid accrued interest under this Note on the date of conversion by (y) the applicable Conversion Price. At least five (5) days prior to the closing of the Next Equity Financing, the Company will notify the Holder in writing of the terms of the Equity Securities that are expected to be issued in such financing. The issuance of Conversion Shares pursuant to the conversion of this Note will be on, and subject to, the same terms and conditions applicable to the Equity Securities issued in the Next Equity Financing.

3.3       Corporate Transaction Conversion. In the event of a Corporate Transaction prior to the conversion of this Note pursuant to Section 3.2 or Section 3.4 or the repayment of this Note, at the closing of such Corporate Transaction, the Holder may elect that either: (a) the Company will pay the Holder an amount equal to the sum of (x) all accrued and unpaid interest due on this Note and (y) the outstanding principal balance of this Note; or (b) this Note will convert into that number of Conversion Shares equal to the quotient (rounded down to the nearest whole share) obtained by dividing (x) the outstanding principal balance and unpaid accrued interest of this Note on the date of conversion by (y) the applicable Conversion Price.

3.4       Maturity Conversion. At any time on or after the Maturity Date, at the election of the Holder, this Note will convert into that number of Conversion Shares equal to the quotient (rounded down to the nearest whole share) obtained by dividing (x) the outstanding principal balance and unpaid accrued interest of this Note on the date of such conversion by (y) the applicable Conversion Price.

3.5       Mandatory Conversion. In the event that, at any time while this Note shall remain outstanding, a conversion of the senior and junior debts of Titan CNG LLC represented by those certain promissory notes set forth on Exhibit A attached hereto (collectively, the “Debts”) shall occur, the entire outstanding principal amount and all interest accrued and unpaid on the Note shall automatically convert upon the full conversion of the Debts, with no further action by the Holder, on the same terms and conditions as those received by the holders of the Debts. For the avoidance of doubt, the Holder shall receive a conversion on the most favorable terms and conditions provided to any holder of the Debts. Notwithstanding anything to the contrary, this Section 3.5 shall be effective only as of the effective time of that certain Agreement and Plan of Securities Exchange by and among the Company, Titan CNG LLC and the Members of Titan CNG LLC identified therein, dated as of November 22, 2016.

3.6       Conversion Mechanism.

(a)       Financing Agreements. The Holder acknowledges that the conversion of this Note into Conversion Shares pursuant to Section 3.2 or Section 3.5 may require the Holder's execution of certain agreements relating to the purchase and sale of the Conversion Shares, as well as registration rights, rights of first refusal and co-sale, rights of first offer and voting rights, if any, relating to such securities (collectively, the “Financing Agreements”). The Holder agrees to execute all of the Financing Agreements in connection with a Next Equity Financing.

(b)       Certificates. As promptly as practicable after the conversion of this Note and the issuance of the Conversion Shares, the Company (at its expense) will issue and deliver a certificate or certificates evidencing the Conversion Shares (if certificated) to the Holder, or if the Conversion Shares are not certificated, will deliver a true and correct copy of the Company's share register reflecting the Conversion Shares held by the Holder. The Company will not be required to issue or deliver the Conversion Shares until the Holder has surrendered this Note to the Company (or provided an instrument of cancellation or affidavit of loss). The conversion of this Note pursuant to Section 3.2 and Section 3.3 may be made contingent upon the closing of the Next Equity Financing and Corporate Transaction, respectively.

4.       Representations and Warranties of the Company. In connection with the transactions contemplated by this Note, the Company hereby represents and warrants to the Holder as follows:

4.1       Due Organization; Qualification and Good Standing. The Company is a corporation duly organized, validly existing and in good standing under the laws of the State of Delaware and has all requisite corporate power and authority to carry on its business as now conducted. The Company is duly qualified to transact business and is in good standing in each jurisdiction in which the failure to so qualify or to be in good standing would have a material adverse effect on the Company.

5.1       Authorization. The Holder has full power and authority (and, if an individual, the capacity) to enter into this Note and to perform all obligations required to be performed by it hereunder. This Note, when executed and delivered by the Holder, will constitute the Holder's valid and legally binding obligation, enforceable in accordance with its terms, except (a) as limited by applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance and any other laws of general application affecting enforcement of creditors' rights generally, and (b) as limited by laws relating to the availability of specific performance, injunctive relief or other equitable remedies.

5.2       Purchase Entirely for Own Account. The Holder acknowledges that this Note is made with the Holder in reliance upon the Holder's representation to the Company, which the Holder hereby confirms by executing this Note, that this Note, the Conversion Shares, and any Common Stock issuable upon conversion of the Conversion Shares (collectively, the “Securities”) will be acquired for investment for the Holder's own account, not as a nominee or agent (unless otherwise specified on the Holder's signature page hereto), and not with a view to the resale or distribution of any part thereof, and that the Holder has no present intention of selling, granting any participation in, or otherwise distributing the same. By executing this Note, the Holder further represents that the Holder does not have any contract, undertaking, agreement or arrangement with any person to sell, transfer or grant participations to such person or to any third person, with respect to the Securities.

In deciding to acquire the Securities, the Holder is not relying on the advice or recommendations of the Company and has made its own independent decision that the investment in the Securities is suitable and appropriate for the Holder. The Holder understands that no federal or state agency has passed upon the merits or risks of an investment in the Securities or made any finding or determination concerning the fairness or advisability of this investment.

5.4       Investment Experience.

5.6       Restricted Securities. The Holder understands that the Securities have not been, and will not be, registered under the Securities Act or state securities laws, by reason of specific exemptions from the registration provisions thereof which depend upon, among other things, the bona fide nature of the investment intent and the accuracy of the Holder's representations as expressed herein. The Holder understands that the Securities are “restricted securities” under U.S. federal and applicable state securities laws and that, pursuant to these laws, the Holder must hold the Securities indefinitely unless they are registered with the Securities and Exchange Commission (“SEC”) and registered or qualified by state authorities, or an exemption from such registration and qualification requirements is available. The Holder acknowledges that the Company has no obligation to register or qualify the Securities for resale and further acknowledges that, if an exemption from registration or qualification is available, it may be conditioned on various requirements including, but not limited to, the time and manner of sale, the holding period for the Securities, and on requirements relating to the Company which are outside of the Holder's control, and which the Company is under no obligation, and may not be able, to satisfy.

5.7       No General Solicitation. The Holder, and its officers, directors, employees, agents, stockholders or partners have not either directly or indirectly, including through a broker or finder solicited offers for or offered or sold the Securities by means of any form of general solicitation or general advertising within the meaning of Rule 502 of Regulation D under the Securities Act or in any manner involving a public offering within the meaning of Section 4(a)(2) of the Securities Act. The Holder acknowledges that neither the Company nor any other person offered to sell the Securities to it by means of any form of general solicitation or advertising within the meaning of Rule 502 of Regulation D under the Securities Act or in any manner involving a public offering within the meaning of Section 4(a)(2) of the Securities Act.
