1例句一

If the Company shall default in making payment in full in respect of any Bonds, the Conversion Right attaching to such Bond will continue to be exercisable up to the earlier of (a)the close of business (at the place where the Bond is deposited for conversion) on the date upon which the full amount of the moneys payable in respect of such Bond has been duly received by the Bondholder, or (b)if such full amount has been received by the Paying Agent, on the date upon which notice of such receipt has been duly given to the relevant Bondholder(s).
