Make dns2 a master server for the "unixlab1.company.com" zone, and put that
IP address in that zone file.  Have it use "forwarders { <dns1>; };" to
look up everything else through dns1.  I.e. named.conf will contain:

zone "unixlab1.company.com" {
  type master;
  file "db.unixlab1";
};

and the file db.unixlab1 will look like:

@ IN SOA ...
  IN NS dns2.company.com.
  IN A 192.168.254.15
