Application note for LPS25H?

I am interested in the LPS25H MEMS barometer chip, but I am having a hard time figuring out the footprint of the HCLGA-10L package.

Here is what is called out in the datasheet:

I cannot decipher from his what the dimensions of the pads should be.  I believe that e1/2 might give me the width, but I cannot determine the length.  Maybe that's what B is supposed to mean, but I don't see it.

Also, I found that there is a good app note for the LPS331AP but cannot find one for the LPS25H.  I realize it's a very new part, but this would help -- it provides some guidance on how the pads should be laid out.

Can someone more mechanically inclined parse this for me?

Thanks.
