Microsot Threat Management Gateway 2010

Can someone give me a diagram of the location of TMG (Threat Management Gateway) when it is used to work with Exchange 2010.

for instance :
Firewall->TMG-Exchange Edge->Firewal-> Hub/CAS - Mailbox

I believe it is preferred to put TMG in the DMZ along with Exchange Edge Server. in this case, Where should I install Anti Spam , Anti Virus, Anti Malware ? should I install them on TMG server or Edge Server? and do I need 2 TMG servers and 2 Edge servers for fault tolerance and/or Load balancing?

Any help will be very much appreciated.

Do you have a link to a diagram or you can just describe the lay out of TMG with Exchange 2010.

for instance:
Firewall->TMG-Exchange Edge->Firewal-> Hub/CAS - Mailbox
if you have the capability i.e. money, infrastructure etc then

External Firewall
Two Load Balanced TMG
Exchange Edge x 2
Internal Firewall

A point to bear in mind there is no more TMG after 2014, and unless you already have the licences you will be unlikely to get hold of it.

you will need to consider some other kind of reverse proxy to replace TMG
