E received a loan from the Industrial Bank of Korea on May 24, 2002, and offered all of the steel towers, containers, and interior facilities (hereinafter “communication facilities”) for communications installed in six relay stations as security for transfer, and as E fails to repay the above loan, the Industrial Bank of Korea sold facilities to F Co., Ltd.

G was granted a loan of KRW 370 million from the Korea Credit Guarantee Fund under Defendant D’s joint and several sureties in 2000. Since G was unable to pay KRW 216 million out of the above loans, G entered into an agreement on the transfer of partnership shares with the effect that Defendant D would transfer 30 million of the above loans to Defendant D, in return for Defendant D’s repayment of KRW 216 million of the above loans, G would transfer 30 million of the above loans to Defendant B, who is the wife of Defendant D.
