As an NES but not a teacher, I would personally not be unhappy with the original and option 1.
With option 2, I would replace "shall" with "will" or "can".
I personally would use "shall" for requirements that I place on others (in commercial contracts), whereas I would use "will" for things that I do, as part of my normal operation, to help the operation of the contract, particularly where government agencies are concerned.
In your case I would feel that "can" is probably the better option, other than omitting the word, as previously.
Hope this helps
