On October 10, 2025, the Company
entered into a certain securities purchase agreement (the “Purchase Agreement”) with certain non-affiliated institutional
investors (the “Purchasers”) pursuant to which the Company agreed to sell (1) 1,000,000 Class A ordinary shares (the “Ordinary
Shares”), and (2) in a concurrent private placement, restricted warrants to purchase an aggregate of up to 2,000,000 Ordinary Shares
(the “Investor Warrants”), for aggregate gross proceeds of approximately $2 million (the “Offering”). The Company
currently intends to use the net proceeds from the Offering for working capital and general corporate use. Additionally, some of the proceeds
from the Offering will be used to fund expenses expected to be incurred in connection with the Acquisition and for general working capital
of the two companies pending the anticipated closing of the Acquisition, which is subject to several closing conditions. The Offering
closed on October 14, 2025.

Each Investor Warrant is exercisable
immediately as of the date of issuance at an exercise price of $2.00 per Ordinary Share and expires twenty-four months from the effective
date of a registration statement registering for resale the Ordinary Shares underlying the Investor Warrants.

H.C. Wainwright & Co.,
LLC, acted as the exclusive placement agent (the “Placement Agent”), in connection with the Offering. The Company agreed to
pay the Placement Agent an aggregate cash fee equal to 7.0
