Help with mask

Hi,

I'm trying to crack a 7z password. I have the hash and have a started a brute force, but as i'm fairly sure what teh make up of the password is I thought a mask would be easier (currently estimated 124 years!!!!).

Could someone help me out?

What I know:

1. It contains a static 5 letter word. I know what the word is but for the example lets say its 'boats'
   
2. Any letter can be uppercase or lower case i.e Boats / BoAts / bOATS
   
3. It can have up to 4 numbers before and/or after and im failry certain they are either 1 or 0 ie. 0101boats / 0101boats0101 / 01boats01 / boats01
   
4. It may or may not have an '!' mark at the end ie. boats01!
   

This it the code I'm running at the moment
C:\hashcat1>Hashcat64.exe -a 3 -m 11600 hash.txt

I have the beta installed 4.1.1-2
Windows 10

Thanks
