I think the annual sale of300 pianos for a sole distributorship in Canada is rather conservative. 我認為對加拿大整個地區的獨家經銷來說,年銷售量三百架鋼琴未免太保守了。
Any change amendment or modification to this EXCLUSIVE DISTRIBUTORSHIP shall not be valid and binding unless the same is reduced in writing duly signed by all. 任何改變修正或修改這一獨家經銷不得有效和有約束力的,除非同時減少書面正式簽署所有。
