WHEREAS, the Company and KAF desire to amend the Forward Stock Purchase
Agreement (the “Purchase Agreement”), dated October 1, 2019, as provided below.

NOW, THEREFORE, in consideration of the premises, representations, warranties
and the mutual covenants contained in this Amendment, and for other good and
valuable consideration, the receipt, sufficiency and adequacy of which are
hereby acknowledged, the parties hereto agree as follows:

Agreement

1.    Amendment to Purchase Agreement. Section 5.b. of the Purchase Agreement is
hereby amended and restated in its entirety as follows:

“Option to Purchase Additional Rights. The Company hereby acknowledges that
nothing in this Purchase Agreement shall prohibit KAF from purchasing up to an
additional 3,750,000 Rights (the “Additional Rights”) after October 1, 2019 and
prior to the closing of the Business Combination. Any such Additional Rights
shall convert into additional Shares (the “Additional Shares”) upon the Business
Combination. KAF’s Additional Shares shall be purchased by the Company in
accordance with Section 1.”

2.    Effect of Amendment. Except as specifically set forth in this Amendment,
all the terms, conditions and covenants set forth in the Purchase Agreement
shall remain unmodified and in full force and effect and are ratified in all
respects.

3.    General Provisions.

a.    After the effective date of this Amendment, any reference to the Purchase
Agreement shall mean the Purchase Agreement as supplemented by this Amendment.
Notwithstanding anything to the contrary in the Purchase Agreement, in the event
of a conflict between the terms and conditions of this Amendment and those
contained within the Purchase Agreement, the terms and conditions of this
Amendment shall prevail.

b.    By signing below, each of the signatories hereto represent that they have
the authority to execute this Amendment and to bind the party on whose behalf
this Amendment is executed.

c.    This Amendment may be executed in two or more counterparts, each of which
