I have another model, a 2006 lexor- I was able to access from the cabinet below the sink.
I removed the whole thing to fix it- I could have done the repair with it in place- mine was leaking from the base of the ball lever, but the previous owner had been under there and i wanted to check his work.
I couldn't see any brand name on it
once the handle is removed you can get to the valving seals below it.
I took the parts and matched up
I was able to get the seals I needed from home depot in a blister pack I think from DANCO- I looked, and i guess I didn;t keep the packaging
as I recall- the faucet seats worked well, but the springs in the kits were too long, so i re-used the original springs.
with the design of the valve, it may be possible that all you need to do is tighten the top of the assembly and put more pressure on the faucet seats- rather than open it up and start replacing parts
