Amazon Kindle Direct Publishing exclusivity question?

[Peter]

This is already described in KDP help:
"What does it mean to publish exclusively on Kindle?
When you choose KDP Select for a book, you’re committing to make the digital format of that book available exclusively through the Kindle Store. When your book is enrolled in KDP Select, you cannot distribute your book digitally anywhere else, including on your website, blogs, etc. However, you can continue to distribute your book in physical format, or in any format other than digital. If your KDP Select-enrolled book is found to be available elsewhere in digital format, it may not be eligible to remain in the program. See the KDP Select Terms and Conditions for more information."

So - in short you can, but only if digital version is only KDP.
