4 The decision to publish Conversion Versions rest solely with the Publishers.

5 If the Conversion Versions shall be prepared at the Publisher’s expense, the Author shall make available all reasonable documentation and other assistance. In the circumstances, the royalties payable shall be as follows:

Physical sales: 2 per cent
