The mortgagee and the mortgagor may,upon agreement, modify such content as the place in the order of mortgage and the amount of secured claim, provided that such modification shall not have any adverse effect on any other mortgagee without the written consent of any other mortgagee. 抵押权人与抵押人可以协议变更抵押权顺位以及被担保的债权数额等内容。但是，抵押权的变更未经其他抵押权人书面同意的，不得对其他抵押权人产生不利影响。 Where the debtor creates mortgage with the property thereof, if the mortgage waives the mortgage or place in the order of mortgage or makes any modification in respect of the mortgage thereof, other guarantors shall be exempted from the suretyship to the extent that the mortgagee forfeits the priority of compensation, unless other guarantors are still committed to the suretyship. 债务人以自己的财产设定抵押，抵押权人放弃该抵押权、抵押权顺位或者变更抵押权的，其他担保人在抵押权人丧失优先受偿权益的范围内免除担保责任，但是其他担保人承诺仍然提供担保的除外。
