一、立約人之授信，其擔保維持率依授信總餘額合併計算整戶擔保維持率。其維持率之計算為：擔保上市有價證券現行市值／授信總餘額×一○○％。

二、如因質押標的物市價變動致擔保維持率低於　　 ％時，由　貴行通知立約人補繳差額。

三、經　貴行通知日後二個營業日內，整戶擔保維持率仍未達第二條之維持率，且未經立約人補繳差額時，對　貴行所負之債務，即表失期限利益，視同全部到期，　貴行得自該營業日起在公開市場上拍賣或變賣質押標的物，以抵償所欠本息。有關質押物處分之方法及價格，概委託由　貴行全權處理，並以本條款為授權之證明。

五、立約人雖未補繳差額或僅補繳一部份而整戶擔保維持率回升至第二條維持率加計三十％以上或於處分質押標的物前立約人陸續繳納差額合計達到通知之補繳差額者，則取銷該次追補記錄，但　貴行有權不受本條之拘束。

六、立約人所提供之質押標的物，　貴行同意其孳息由出質人領取，惟立約人同意自該孳息之除權息基準日前七個營業日起，以除權息後之參考價格作為計算整戶擔保維持率之標準。

七、倘立約人或擔保物發行公司的業務、財務及信用發生狀況，以致損害　貴行之權利並損及借款人或出質人之利益，借款人或出質人同意　貴行經自行評估認為可能損及債權時，貴行得依民法第八九二條拍賣質物，以賣得價金，代充質物。

前項之拍賣，因情形急迫時，借款人或出質人同意免除　貴行之通知義務。

第一項拍賣與否，係　貴行之權利，　貴行無拍賣之義務。
