I need help with syntax

[Quest]

here's a new challenge.

I'm looking to build a syntax that would cover certain criteria.
A capture.hccap is the target. I'm using cudaHashcat 1.30

- 8 character long.
- first character is both a Capitalized letter and a lower case (-u -l).
- last four characters are numbers, Capitalized letters, lower case (all except symbols (-u -l -d)).
- between the first position and the last four, all lower case (-l).
