shall be calculated applying the formula defined below:
 
P = (OC / US) * MS, where
 
P – milestone payment due to Licensor in connection with obtaining regulatory
approval in any Other Country;
 
OC – the size of the pharmaceutical market of the Other Country in US dollars at
the time;

applicable annual DSM Group (located at 7/2, 5-th Yamskogo Polya St. Moscow
125040 Russia) report or other generally accepted annual market data report.
However, if a milestone that was first reached in an Other Country is
subsequently achieved or surpassed in the United States, such as by relying on
foreign clinical trials to support United States Food and Drug Administration
(“FDA”) approval, CBL shall pay CCF the difference between what was paid for the
milestone in all Other Countries, if any, and what would have been due under the
applicable section if the milestone had first occurred in the United
States.  For purposes of clarity, the maximum amount of milestone payments CBL
shall be obligated to pay to CCF pursuant to this Agreement shall be the
aggregate of the amounts set forth in the applicable subsection of Section 4.B.
