HTTP TO HTTPS (with exception urls)

I have several domains hosted on one server. I recently bought an SSL certificate which can only secure FIVE of these domains, so I need some code that will create EXCEPTIONS for the domains that are not secure.

The main code to redirect all domains to HTTPS is this:

RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

How do I add an exception for unsecured domains called "myexception1.com" and "myexception2.com?

In other words I DO NOT want "myexception1.com" and "myexception2.com" to be redirected to HTTPS like the rest of the domains. I want them to open up as HTTP urls (unsecured).

Thanks in advance!
