How many names needed for SAN Certificate for Exchange 2013 server with multiple name

We are trying to figure out on how many names will be sufficient to meet our requirements for a SAN certificate that will be installed on Microsoft Exchange server 2013. Below is a list of our domains (fictitious names):

Internal Domain - abc.abc.com (Mail server is  mail10.abc.abc.com)
External Domain - abc.com  (email domain)
Additional External Domain - xyz.com (users email address = user@xyz.com)

In our setup the AD domain is abc.abc.com, the email domain for most people is xyz.com, but we also have some people that have email addresses @abc.com.
So when I buy the SSL certificate, I assume I would need:

mail.abc.com
autodiscover.abc.com
mail.xyz.com
autodiscover.xyz.com

Is this correct or do i need more or less? Any input is appreciated.

You need only two names if you have one email domain.
which is you common name and autodiscover.
e.g. mail.domain.com and autodiscover.domain.com
