以上是我搜到的原文，可供参考。你所提问的句子在内。

由前文Any proposed or final settlement agreement shall include each of the following statements可知，和解协议要包含如下声明，其中（B）项是“诉讼之可能后果的声明”。

（B）项提到的第一种“可能的后果”，即“就损害赔偿的数额达成一致”，而第二种“可能的后果”是“无法就损害赔偿的数额达成一致”。

综览该网页上的全文，可知其涉及私有证券诉讼。据此，现将你提问的句子试译如下：

如果起诉方在本细目（subchapter）下提出的任何主张均获支持，从而使取得每股损害赔偿成为可能，并且和解各方在赔偿平均数额上达成一致，则就该可能之每股损害赔偿的平均数额出具一份声明。

你这里问到的句子确切地说不是完整的句子，类似于汉语这样说话：

请务必附上如下声明：1、如果就平均数额达成一致，关于平均数额的声明；2、如果无法就平均数额达成一致，关于存在问题的声明。

提醒：法律翻译属格式化专业翻译，我们最好量力而行，我的意思，不是万不得已，不是十分把握，不是具备了相关的法律知识，不要也无需轻易尝试。对专门法律语言的陌生与否并不足证明我们语言素养的高低。
