all times and to indemnify and fully hold Alesis and its successors and assigns harmless in the
event of any failure to so perform.
Your purchase of the Manual shall be for your own ultimate use and shall not be for purposes of
resale or other transfer.

or (ii) to any third parties for any purpose.
You shall not make any warranties or guarantees with respect to the products of Alesis or the use
thereof on behalf of Alesis or in your own name.
