Securities Subscription Agreement

On April 19, 2018, the Issuer issued to the Sponsor an aggregate of 10,750,000 Class B ordinary shares (“Founder Shares”) in exchange for a capital contribution of $25,000 pursuant to a securities subscription agreement, dated as of April 19, 2018 (the “Securities Subscription Agreement”). The foregoing description of the Securities Subscription Agreement is qualified in its entirety by reference to the Securities Subscription Agreement, which is attached hereto as Exhibit 1.

The Founder Shares will automatically convert into Class A Ordinary Shares on the first business day following the consummation of the Issuer’s initial business combination at a ratio such that the total number of Class A Ordinary Shares issuable upon conversion of all Founder Shares will equal, on an as-converted basis, 20% of the sum of (i) the total number of Class A Ordinary Shares, plus (ii) the sum of  (a) the total number of Class A Ordinary Shares issued or deemed issued or issuable upon conversion or exercise of any equity-linked securities or rights issued or deemed issued by the Issuer in connection with or in relation to the consummation of the Issuer’s initial business combination (including the Forward Purchase Shares (as defined below), but not the Forward Purchase Warrants (as defined below)), excluding any Class A Ordinary Shares or equity-linked securities exercisable for or convertible into Class A Ordinary Shares issued, or to be issued, to any seller in the initial business combination and any warrants issued in a private placement to the Sponsor or an affiliate of the Sponsor upon conversion of working capital loans, minus (b) the number of Class A Ordinary Shares included in the units sold in the Issuer’s initial public offering redeemed in connection with the Issuer’s initial business combination.

Letter Agreement

On June 27, 2018, the Reporting Persons agreed, pursuant to a letter agreement with the Issuer (the “Letter Agreement”), to (i) waive their redemption rights with respect to their Founder Shares and Class A Ordinary Shares in connection with the completion of the Issuer’s initial business combination, (ii) waive their redemption rights with respect to their Founder Shares and Class A Ordinary Shares in connection with a shareholder vote to approve an amendment to the Issuer’s amended and restated memorandum and articles of association to modify the substance or timing of the Issuer’s obligation to redeem 100% of the Class A Ordinary Shares if the Issuer has not consummated an initial business combination within 24 months from the closing of its initial public offering and (iii) waive their rights to liquidating distributions from the trust account with respect to their Founder Shares if the Issuer fails to complete its initial business combination within 24 months from the closing of its initial public offering (although they will be entitled to liquidating distributions from the trust account with respect to any Class A Ordinary Shares they hold if the Issuer fails to complete its initial business combination within the prescribed time frame). If the Issuer submits its initial business combination to its shareholders for a vote, the Reporting Persons have agreed to vote their Founder Shares in favor of the initial business combination, and the Reporting Persons have also agreed to vote any Class A Ordinary Shares in favor of the initial business combination.

In addition, pursuant to the Letter Agreement, the Sponsor, Mr. Leung and Mr. Wu agreed not to transfer, assign or sell any of its or his Founder Shares and any Class A Ordinary Shares issued upon conversion thereof until the earlier of (a) one year after the completion of the Issuer’s initial business combination with respect to 50% of its or his Founder Shares and any Class A Ordinary Shares issued upon conversion thereof, (b) two years after the completion of the Issuer’s initial business combination with respect to the remaining 50% of its or his Founder Shares and any Class A Ordinary Shares issued upon conversion thereof, and (c) the date on which the Issuer completes a liquidation, merger, share exchange or other similar transaction after its initial business combination that results in all of its shareholders having the right to exchange their Class A Ordinary Shares for cash, securities or other property. Notwithstanding the foregoing, the lock-up provisions do not apply to transfers, assignments or sales (a) to the Issuer’s officers or directors, any affiliate or family member of any of the Issuer’s officers or directors, any affiliate of the Sponsor or to any member of the Sponsor or any of their affiliates or shareholders, (b) in the case of an individual, as a gift to such person’s immediate family or to a trust, the beneficiary of which is a member of such person’s immediate family, an affiliate of such person or to a charitable organization; (c) in the case of an individual, by virtue of laws of descent and distribution upon death of such person; (d) in the case of an individual, pursuant to a qualified domestic relations order; (e) by private sales or transfers made in connection with any forward purchase agreement or similar arrangement or in connection with the consummation of a business combination at prices no greater than the price at which the shares were originally purchased; (f) by virtue of the laws of the Cayman Islands upon dissolution of the Sponsor, (g) in the event of the Issuer’s liquidation prior to the consummation of its initial business combination; or (h) in the event that, subsequent to the consummation of an initial business combination, the Issuer completes a liquidation, merger, share exchange or other similar transaction which results in all of the Issuer’s shareholders having the right to exchange their Class A Ordinary Shares for cash, securities or other property; provided, however, that in the case of clauses (a) through (f) these permitted transferees must enter into a written agreement agreeing to be bound by these transfer restrictions and the other restrictions contained in the Letter Agreement.

Under the Letter Agreement, the Sponsor has agreed to transfer to each of the Issuer’s independent directors for services rendered as board members prior to the completion of the Issuer’s initial business combination 10,000 Founder Shares if such directors elect to receive such shares in lieu of $50,000 per year from the Issuer in cash.

In addition, the Letter Agreement provides that in order to finance transaction costs in connection with an intended initial business combination, the Sponsor or its affiliate may, but is not obligated to, loan to the Issuer funds as may be required on a non-interest basis. If the Issuer completes an initial business combination, the Issuer would repay such loaned amounts. In the event that the initial business combination does not close, the Issuer may use a portion of the working capital held outside its trust account to repay such loaned amounts but no proceeds from its trust account would be used for such repayment. Up to $2,000,000 of such loans may be convertible into warrants of the post business combination entity at a price of  $1.00 per warrant at the option of the lender. The warrants would be identical to the Private Placement Warrants (defined below). Except as set forth above, the terms of such loans, if any, have not been determined and no written agreements exist with respect to such loans.

The foregoing description of the Letter Agreement is qualified in its entirety by reference to the Letter Agreement which is attached hereto as Exhibit 2.

Private Placement Warrants Purchase Agreement

On June 27, 2018, the Sponsor purchased from the Issuer an aggregate of 7,750,000 warrants (the “Private Placement Warrants”) pursuant to the terms of a private placement warrants purchase agreement, dated as of June 27, 2018 (the “Private Placement Warrants Purchase Agreement”). Each private placement warrant entitles the holder thereof to purchase one Class A Ordinary Share at $11.50 per share. The Private Placement Warrants (including the Class A Ordinary Shares issuable upon exercise of the Private Placement Warrants) are not transferable, assignable or salable until 30 days after the completion of the Issuer’s initial business combination, and they will be non-redeemable so long as they are held by the Sponsor or its permitted transferees. Otherwise, the Private Placement Warrants have terms and provisions that are identical to those of the warrants sold as part of the units in the Issuer’s initial public offering. The foregoing description of the Private Placement Warrants Purchase Agreement is qualified in its entirety by reference to the Private Placement Warrants Purchase Agreement which is attached hereto as Exhibit 3.

Registration Rights Agreement

On June 27, 2018, the Issuer and the Sponsor entered into a registration rights agreement (the “Registration Rights Agreement”) which provides for registration rights for the holders of the Founder Shares, Private Placement Warrants purchased by the Sponsor and warrants that may be issued to the Sponsor or an affiliate of the Sponsor upon conversion of working capital loans. These holders are entitled to make up to three demands, excluding short form registration demands, that the Issuer register such securities for sale under the Securities Act of 1933, as amended (the “Securities Act”). In addition, these holders will have certain “piggy-back” registration rights with respect to registration statements filed subsequent to the Issuer’s completion of its initial business combination. However, the Registration Rights Agreement provides that the Issuer will not permit any registration statement filed under the Securities Act to become effective until termination of the applicable lockup period relating to such securities. The foregoing description of the Registration Rights Agreement is qualified in its entirety by reference to the Registration Rights Agreement which is attached hereto as Exhibit 4.

Forward Purchase Agreements

On June 4, 2018 and June 29, 2018, the Issuer entered into forward purchase agreements pursuant to which certain investors (the “Anchor Investors”) agreed to purchase an aggregate of 19,000,000 Class A Ordinary Shares (“Forward Purchase Shares”) plus an aggregate of 4,750,000 redeemable warrants (“Forward Purchase Warrants”) in a private placement to occur concurrently with the closing of the Issuer’s initial business combination.

Among such forward purchase agreements, the Issuer entered into a forward purchase agreement with (i) Carnival Investments Limited, an entity controlled by Mr. Leung, providing for the sale of 1,400,000 Forward Purchase Shares and 350,000 Forward Purchase Warrants for an aggregate purchase price of $10.00 per forward purchase share, or $14,000,000 and (ii) Max Rising International Limited, an entity controlled by Mr. Wu, providing for the sale of 700,000 Forward Purchase Shares and 175,000 Forward Purchase Warrants for an aggregate purchase price of $10.00 per forward purchase share, or $7,000,000. In connection with the forward purchase agreements, the Sponsor transferred to certain of the Anchor Investors 2,262,500 Founder Shares, including 175,000 to Carnival Investments Limited and 87,500 to Max Rising International Limited.

Pursuant to the forward purchase agreements, the Issuer agreed to use its commercially reasonable efforts (i) to file within 30 days after the closing of its initial business combination, or following announcement of the results of the shareholder vote relating to its initial business combination or the results of its offer to shareholders to redeem their Class A Ordinary Shares in connection with its initial business combination (whichever is later) (the “disclosure date”), a registration statement with the U.S. Securities and Exchange Commission for a secondary offering of the Forward Purchase Shares and the Forward Purchase Warrants (and underlying Class A Ordinary Shares), (ii) to cause such registration statement to be declared effective promptly thereafter, but in no event later than 60 days after the closing of the initial business combination or the disclosure date, as the case may be and (iii) to maintain the effectiveness of such registration statement until the earliest of  (A) the date on which the anchor investor ceases to hold the securities covered thereby and (B) the date all of the securities covered thereby can be sold publicly without restriction or limitation under Rule 144 under the Securities Act, subject to certain conditions and limitations set forth in the forward purchase agreements.

The foregoing description of the forward purchase agreements is qualified in its entirety by reference to the form of forward purchase agreement which is attached hereto as Exhibit 5.

On June 12, 2018, the Sponsor forfeited 475,000 Founder Shares to the Issuer for no consideration. On June 18, 2018 and June 27, 2018, the Issuer effected share capitalizations resulting in the Sponsor holding an aggregate of 9,450,000 Founder Shares, after giving effect to the transfer of 2,262,500 Founder Shares described above.

Units Purchased in Initial Public Offering

On June 28, 2018, Mr. Leung and Mr. Wu purchased 600,000 and 300,000 units, respectively, in the Issuer’s initial public offering. Each unit consists of one Class A Ordinary Share and one-half of one redeemable warrant, with each whole warrant entitling the holder thereof to purchase one Class A Ordinary Share at a price of $11.50 per share. The warrants will become exercisable on the later of 30 days after the completion of the Issuer’s initial business combination or 12 months from the closing of the Issuer’s initial public offering. The warrants will expire five years after the completion of the Issuer’s initial business combination or earlier upon redemption or liquidation.
