LibreOffice Licence - quick questions


I work for an OEM company.
Can someone please answer me tthis:

  1. Can we freely include LibreOffice 4.XX (latest version) in our MS W*ndows machines?

  2. Do we need to include LibreOffice source code as well (LibreOffice will be distributed “as is” - without any modifications).

  3. What other things should we take into consideration (if any exist) in order to distribute MS W*ndows+LibreOffice to our customers?

Thank you.
