sevarance and golden parachute for executive/officer

Can I get some help on Executive Officer Severance/compensation agreement and Golden Parachute/Exit Strategy agreement?
Situation. My company is 5 years old.
I own 50% of it with with partner.
He is ex banker. We are negotiating to sell our company to a new bank that will be heavily capitalized and I am not worried at all about bank default or failure in the next 5 - 10 years.
They are buying my company for $1.5 million of which $500k is debt payoff and $1.0 mil is stock in new bank with me being 12% bank owner/officer.
What I want is an agreement that says that I receive 3- 4 years of compensation if they let me go without cause and I want fair market value of stock paid also if that happens or at least retain rights to stock. Same or better agreement for merger or acquisition of another buyer if we sell out in future.
