En-Tan-Mo IEO Sale Rule

I. Participation

The subscription-allotment process will continue to be implemented on OK Jumpstart. However, a 2nd Subscription Session will be added to the token sale. The token sale will follow the procedure of subscription > allotment > result announcement, and only OKB holders can participate in the sale. Participation steps are as follows:

Step 1: Prepare and Hold OKB

OKB is the only token accepted for subscription and settlement. To be eligible to participate in the 2nd token sale, you are required to have a minimum of 500 OKB for your 15-day Average OKB Holding Amount. The more the OKB you hold, the greater the allotment you can get (details below). Your account will be snapshotted daily at a random time (starting Apr 25, HKT). From the 3rd token sale and onwards, you are required to have a minimum of 500 OKB for your 30-day Average OKB Holding Amount for participation. The individual cap of subscription will be announced prior to the token sale.

Step 2: Subscribe (2 Sessions available)

1st Session:Over-subscription limit Session time limit is 10 minutes. However, the session will end early once the over-subscription limit is reached. 2nd Session: NO over-subscription limit. Session time limit is 10 minutes. Users who subscribe successfully within this time frame will get an allotment. Allotment calculation and result announcement follow after each session ends. The token allocation for the 1st and 2nd sessions will be made known in each round�s token sale announcement.

Step 3: Allotment

Once the allotment calculation is done, tokens will be credited to users� OKEx Assets Account and the corresponding amount of OKB will be deducted. Any OKB on hold for unallotted subscription will be released. Allotment for the 1st session will be carried out before the 2nd session The OKB on hold for unallotted subscription in the 1st session will be released and can be used for the 2nd session.

Note:

Minimum threshold for participating in 2 nd token sale: 15-day Average Holding Amount ? 500 OKB

for participating in 2 token sale: For maximum allotment, a user will have to reach ? 2,500 OKB for the 15-day Average Holding Amount. An allotment coefficient mechanism is adopted. Details are listed in the later part of this announcement.

for the 15-day Average Holding Amount. An allotment coefficient mechanism is adopted. Details are listed in the later part of this announcement. If your OKB holding amount decreases or you stop holding OKB during the 15-day period, you may consider buying back a large amount of OKB before the token sale�s last random snapshot time to reach the participation threshold.

II. Listing

All projects launched on OK Jumpstart will be supported by OKEx and its global partners:

The project listed on OKEx will be launched with trading pair(s) against OKB, BTC, ETH, and USDT. At least one of these trading pairs will be launched on the subscription day.

If the project matches the compliance and other requirements of OKEx�s partners, OKEx may refer the project to fiat-exchanges, such as OKCoin Korea and OKCoin.com, which may offer priority listing opportunities to the project.

IV. Subscription Rules

1. Allotment Coefficient

The allotment of each user is determined by the allotment coefficient, which is based on the user�s Average OKB Holding Amount. In a nutshell, the more the Average OKB Holding Amount you have, the higher the allotment coefficient you will get, and the greater the allotment you will receive.

2. Allotment Formula

Both the 1st and 2nd sessions will follow the same allotment formula below:

3. Example

When the token sale opens, user A, B, C, and D wish to participate in the subscription sessions. Let�s assume their Average OKB Holding Amounts are: A = 500, B = 1,000, C = 3,000, D = 200. According to the table above, the allotment coefficient of user A, B, C, and D will be 1, 2, 5, and 0 respectively. Since the allotment coefficient of user D is 0, he is not eligible for the subscription.

We further assume that the session supply is 300 tokens, and the subscription amount user A, B, and C entered are 800, 300, and 400 respectively. The allotment will be as follows:
