Hi Valery,

Yes, unfortunately we hit some issues and the GEM production is
extending longer than hoped/expected.

Kondo and Nilanga's people are working hard to get out of there as
soon as possible, but I expect it will be at least a few more weeks
at minimum.  I've had a few short conversations with the other folks
that are working in the NW corner/side of the cleanroom and are trying
to stay out of their way.

I have a meetings from 1:30--3pm on Thursday, but would be happy to meet
with you either at the Cleanroom or via Bluejeans outside that period
to discuss the situation.  Just let me know.
