Purchase and sale agreement description         Purchase and Sale Agreement will automatically expire, and the payment of Royalties from the Royalty Sub to HCR will cease, when HCR has received payments of the Royalties equal to 3.4 times the aggregate amount of payments under the Purchase and Sale Agreement (the “Cap Amount”). In the event of a change in control, acquiror will have the option to make a payment to HCR of the Cap Amount, less the aggregate amount of Royalty payments made by Royalty Sub to HCR under the Purchase and Sale Agreement as a one-time payment at which time, payment of Royalties to HCR will cease. Alternatively, in the event of a change in control, the acquiror will have the option to make an initial payment of 1.0 times the aggregate amount of payments made by HCR under the Purchase and Sale Agreement as of the date of such change in control, then in that event, payment of Royalties from Royalty Sub to HCR will cease when HCR has received total Royalties payments (including the initial payment) equal to the Cap Amount. After the Purchase and Sale Agreement expires, all rights to receive the Royalties return to Royalty Sub.
