Rule to exclude a specific IP in Snort

I’m trying to modify the following Snort Rule:

Alert ip any any -> any any (msg:”BAD-TRAFFIC same SCR/DST”; sameip;
reference:cve,CVE-1999-0016;
reference:url,www.cert.org/advisories/CA-1997-28.html;
classtype:bad-unknown; sid:527; rev:4;)

I’m getting an alert on just one ip address and I know what the problem is.
So I’m trying to modify this rule so that it takes into account any internal
ip address except 192.168.10.37.

Hoe do I modify the rule?
