manner at all times and to indemnify and fully hold Alesis and its successors and assigns
harmless in the event of any failure to so perform.

resale or other transfer.
As the owner of the copyright to the Manual, Alesis does not give you the right to copy the
Manual, and you agree not to copy the Manual without the written authorization of Alesis. Alesis
has no obligation to provide to you any correction of, or supplement to, the Manual, or any new
or superseding version thereof.

use thereof on behalf of Alesis or in your own name.
