Exhibit 10.4

This STOCK PURCHASE AGREEMENT (the “Agreement”) is made as of February 19, 2018, by and between Blockchain Industries, Inc., a Nevada corporation with its principal place of business at 53 Calle Palmeras, Suite 802, San Juan, PR 00901 (“BII”) and LegatumX, Inc. (“LegatumX”), a Delaware corporation (each a Party”, and collectively, the “Parties”).

THE PARTIES HEREBY AGREE AS FOLLOWS:

1.                  Purchase and Sale of Stock. Subject to the terms and conditions hereof (including Sections 2, 8 and 9 below), LegatumX shall sell to BII, and BII shall purchase from LegatumX [●] shares of LegatumX’s common stock, par value $0.0001 per share, (the “Initial Shares”) at a price of [●] per share for an aggregate purchase price of One Million Three Hundred Thousand (USD $1,300,000) Dollars (the “Purchase Price”). The Initial Shares shall equal, on a Fully- Diluted Basis (as hereinafter defined), Thirty (30%) percent of the outstanding capital stock of LegatumX immediately following the Closing Date (as hereinafter defined). “Fully-Diluted Basis” means the aggregate number of shares in LegatumX calculated as if all outstanding stock options, warrants and convertible securities have been exercised for or converted into common stock and all options reserved for issuance in the option pool have been issued and exercised for common stock. **[NTD: The Purchase Price, and the corresponding number of Initial Shares, presumably, will correspond to a total ascribed value of LegatumX equal to USD

$4,333,333.33].

2.               Consideration and Issuance of LegatumX Shares. The Purchase Price shall consist of Cash Consideration and Stock Consideration, respectively, each as hereinafter defined.

a.                Cash Consideration. The payments (“Cash Consideration”) to be made by BII to Legatum, and the corresponding number of Initial Shares allocable thereto, shall be as follows:

b.               Stock Consideration. LegatumX shall receive One Hundred Thousand (100,000) shares of common stock of BII (the “BII Stock”) in exchange for such number of Initial Shares equal to Five (5%) percent of the outstanding capital stock LegatumX on a Fully- Diluted Basis.

c.                Earnout Adjustment. The Parties acknowledge that BII anticipates filing with the Securities Exchange Commission (“SEC”) a Form 10 for the registration of the common stock of BII pursuant to Section 12(b) of the Exchange Act (the “Registration Statement”). BII shall use its commercially reasonable efforts to have the Registration Statement declared effective by the SEC on or before December 31, 2018 (the “Registration Deadline”). During the one-year period beginning on the date that the Registration Statement is declared effective by the SEC and ending on the one-year anniversary thereof (the “Earnout Period”), BII and LegatumX shall cooperate with each other, in good faith, in order to determine a mutually-agreeable manner and timing for LegatumX to sell the BII Stock (the “Earnout Period Sales”). If LegatumX realizes gross proceeds on the Earnout Period Sales equal to or exceeding Two Million Three Hundred Thousand (USD $2,300,000) Dollars, BII shall receive additional shares of LegatumX’s common stock equal to Five (5%) percent of the outstanding capital stock LegatumX on a Fully- Diluted Basis (the “Lower Threshold Earnout Shares”). Alternatively, if LegatumX realizes gross proceeds on the Earnout Period Sales equal to or exceeding Ten Million One Hundred Thousand (USD $10,100,000) Dollars, BII shall receive additional shares of LegatumX’s common stock equal to Ten (10%) percent of the outstanding capital stock LegatumX on a Fully- Diluted Basis (the “Higher Threshold Earnout Shares”, and together with the Lower Threshold Earnout Shares, the “Earnout Shares”).

d.               Mandatory Loan. If, as of the Registration Deadline, BII does not have an effective Registration Statement, reasonably promptly thereafter, BII shall make a cash advance, or series of cash advances, to LegatumX in the amount of One Million (USD $1,000,000) Dollars (the “Mandatory Loan”). The Mandatory Loan shall be secured by a first lien priority security interest in all of the BII Stock and shall bear no interest. The Mandatory Loan shall become immediately due and payable upon the earlier to occur of (i) the date the Registration Statement is declared effective by the SEC (the “Registration Effective Date”) or (ii) the sale or issuance by LegatumX of New Securities (as defined in Section 8 below) for cash in a single transaction or series of transaction resulting in gross proceeds equal to or in excess of Five Million (USD $5,000,000) Dollars (a “Qualified Capital Raise”). In the event that a Qualified Capital Raise shall precede and occur prior to the Registration Effective Date, LegatumX repay the full amount of the Mandatory Loan from the proceeds of the Qualified Capital Raise. Upon the Registration Effective Date, LegatumX shall repay the Mandatory Loan if and in such amount as the Mandatory Loan shall remain outstanding and unpaid, and the provisions of Section 2.c. above automatically shall apply with respect to the sale of BII Stock by LegatumX or an affiliate.

3.               Closing. The consummation of the transactions contemplated by this Agreement is herein referred to as the “Closing”, and the date on which the Closing occurs is herein referred to as the “Closing Date.” The Closing shall take place via the electronic exchange of documents and signatures at such other time and place as the BII and LegatumX may mutually agree. At the Closing, LegatumX shall deliver to BII a certificate representing the Initial Shares against payment by BII of the Cash Consideration by check or wire transfer and delivery by BII of a certificate representing the BII Stock to LegatumX.

4.               Optional Loan Agreement. In consideration of LegatumX entering into this Agreement (and not in consideration of any purchase of the Initial Shares or with respect to the Earnout Shares), LegatumX shall have the option to obtain a loan from BII in the principal amount of up to Five Hundred Thousand (USD $500,000) Dollars (the “Optional Loan”) during the second calendar quarter of 2019. The Optional Loan shall be evidenced by a promissory note, subject to a commercially reasonable rate of interest, as mutually agreed upon by the Parties, and secured by a pledge of the BII Stock. The Optional Loan term and maturity schedule shall be determined in the discretion of BII, and the Optional Loan shall be subject to such other terms and conditions as LegatumX and BII set forth in writing (the “Loan Agreement”). The Parties shall enter into an “Optional Loan Agreement”, and the full amount of the Optional Loan shall be transferred to LegatumX, within a commercially reasonable amount of time after written notice requesting the Optional Loan is provided by LegatumX to BII. For the avoidance of doubt, LegatumX shall have no obligation to accept the Optional Loan.

All action on BII’s part required for the lawful execution and delivery of this Agreement has been taken. Upon its execution and delivery, this Agreement will be valid and binding obligations of BII, enforceable in accordance with their terms, except as limited by applicable bankruptcy, insolvency, reorganization, moratorium or other laws of general application affecting enforcement of creditors’ rights.

d.               Full Disclosure. BII has provided LegatumX with all information requested by LegatumX in connection with its decision to enter into this Agreement. Neither this Agreement, the exhibits hereto nor any related agreements contain any untrue statement of a material fact nor, to the BII’s knowledge, omit to state a material fact necessary in order to make the statements contained herein or therein not misleading.

7.               Board Composition: Prior to the completion of a “Qualified Financing” (as hereinafter defined), the board of directors of LegatumX shall be set and remain at Three (3) directors. BII will have the right (the “Designation Right”) to elect at any meeting of shareholders of LegatumX at which directors are to be elected, designated and appointed one (1) member of the board of directors. The parties acknowledge and agree that One (1) member of the board of directors (the “Independent Director”) shall have no material relationship with either LegatumX or BII. The Independent Director shall be designated by the mutual agreement of BII and LegatumX. BII shall have no Designation Right following the completion of a Qualified Financing. A “Qualified Financing” means the sale or issuance by LegatumX of New Securities (as defined in Section 8 below) for cash in a single transaction or series of transactions resulting in gross proceeds equal to or in excess of $100 million.

8.               Anti-Dilution Protection. If BII shall, at any time or from time to time after the Closing Date, but on or before the completion of a Qualified Financing, issue or sell, agree to issue or sell, or be deemed to have issued or sold, any New Securities (as hereinafter defined), where the price per share paid upon purchase or exercise is, or resultant upon conversion into common stock of Legatum (taking into account any and all warrants or other securities and other consideration issued in connection therewith when determining the value of such price per share) would be, less than the Purchase Price, then as a condition precedent to any such issuance or sale (or deemed issuance or sale), LegatumX shall be required to issue to BII additional shares of common stock (the “Adjustment Shares”) to maintain BII’s ownership attributable to both (i) the Initial Shares at Thirty (30%) Percent of LegatumX’s total capital stock on a Fully-Diluted Basis and (ii) the Lower Threshold Earnout Shares, if applicable, at Five (5%) Percent of LegatumX’s total capital stock on a Fully-Diluted Basis, or alternatively the Higher Threshold Earnout Shares, if applicable, at Ten (10%) Percent of LegatumX’s total capital stock on a Fully-Diluted Basis. “New Securities” means shares of the common stock of LegatumX, any other securities, options, warrants or other rights where upon exercise or conversion the purchaser or recipient receives shares of common stock, or other securities with similar rights to the common stock. Within thirty (30) days of the sale or issuance of any such New Securities, LegatumX shall deliver to BII certificates evidencing any Adjustment Shares BII is entitled to hereunder.

9.               Most Favored Nation. Prior to the issuance of any New Securities in an offering (“New Offering”), LegatumX shall provide BII with a notice (the “MFN Notice”) which shall include a copy of the offering documentation provided by LegatumX to solicit investment in the New Offering. The MFN Notice shall also describe in reasonable detail the procedures affording BII the right (“Anti-Dilution Right”) to participate in the New Offering on substantially similar terms with respect to the average price per share of common stock that an investor pays assuming the full conversion or exercise of warrants or similar rights that are issued in the New Offering. BII may exercise its Anti-Dilution Right by providing a notice to such effect to LegatumX on or prior to the date that is thirty (30) days after the date that BII received the MFN Notice. For avoidance of doubt, the Anti-Dilution Right shall terminate on the date that is the earlier of the date that the BII does not duly and timely exercise its Anti-Dilution Right as described in this Section 9 or upon the completion of a Qualified Financing.

15.            Specific Enforcement. The parties hereto acknowledge that money damages would not be an adequate remedy at law if any party fails to perform in any material respect any of its obligations hereunder, and accordingly agree that each party, in addition to any other remedy to which it may be entitled at law or in equity, shall be entitled to seek to compel specific performance of the obligations of the other party under this Agreement, without the posting of any bond, in accordance with the terms and conditions of this Agreement in any court of the United States or any State thereof having jurisdiction, and if any action should be brought in equity to enforce any of the provisions of this Agreement, none of the parties hereto shall raise the defense that there is an adequate remedy at law.
