“Tag-along”翻译为“随售权”，Tag用作动词时是“紧随、尾随”的意思，随售权条款是出售权条款中的一种，通常约定当大股东出售其股权时，小股东有权选择以相同价格同等条件向受让大股东股权的买方出让股权，即“跟随”大股东一起出售股权，也称“共同出售权”（Co-sale）”。

“Drag-along”翻译为“拖售权”或“领售权”，Drag用作动词时是“拖、拽”的意思，拖售权是指如果有第三方向股权投资基金发出股权收购要约，且股权股权投资基金接受该要约，则其有权要求其他股东一起按照相同的出售条件和价格向该第三方转让股权。

Don't let yourself be confused by a lawyer because you don't know what "liquidation preference," "right of first refusal," or "drag along/tag along" means.

不要因为自己不懂“清算优先权”(liquidation preference)、“优先承购权”(right of first refusal)，或者是“拖带权”(drag along/tag along)的含义，而被律师搞的晕头转向。
