(hereinafter “Plaintiff Distribution”), among the remainder claim 350 million won under the instant sales contract (hereinafter “instant remainder claim”), and the Plaintiff Co., Ltd.

2. The parties' assertion

A. The purchase price stipulated in the purchase and sale contract of this case alleged by the plaintiffs is 2.95 billion won, and the defendant paid only 2.6 billion won to E.

E, as above, transfers 350 million won of the balance claim of this case which has not been paid yet to the plaintiffs, and completed the procedure of notification of the assignment of the claim, so the defendant is obligated to pay the plaintiffs the above amount of 350 million won and damages for delay.

B. The Defendant’s assertion that the sales amount stipulated in the instant sales contract is KRW 2.6 billion, and the Defendant paid the above sales amount to E.

Since E does not have any existing claim for the remainder of this case that it transferred to the plaintiffs, the plaintiffs' claim for the takeover of this case is without merit.

3. Determination No. 1-2 and No. 9 are written in each judgment No. 1-9.
