If the stock price is between two stock price amounts in the table or the effective date is between two effective dates in the table, the number of additional shares will be determined by a straight-line interpolation between the number of additional shares set forth for the higher and lower stock price amounts and the two dates, as applicable, based on a 365-day year. In addition, if the stock price is greater than $300 per share (subject to adjustment), the exchange rate will not be adjusted. If the stock price is less than $93.15 per share (subject to adjustment), the exchange rate will not be adjusted. Notwithstanding the foregoing, in no event will the total number of shares of Boston Properties common stock issuable upon exchange exceed 10.7353 per $1,000 principal amount of notes, subject to adjustments.
