Does anyone have any experience using Mezzanine debt in an acquisition? Currently exploring a potential acquisition that would be in the $15M range. Goal would be to structure as follows:

~$12M bank financing
~$2-3M Mezz
~Cross collateralize current business in same industry w/ ~$1M value
~Put in around $500k - $1M cash

Ideally like to keep investors out if at all possible (hence this structure...) any input if its within reason?
