I paid significant C-Corp expenses out of pocket, am a minority shareholder (non-employee), and will not be reimbursed - How do I recognize/deduct these expenses on 1040?

The largest chunk of these expenses were to cover company legal fees; however, there were additional expenses related to misc business meetings as well as a few expenses tied to marketing the business to potential acquirers.  Schedule C doesn't seem to cover C-corporations, and I can't figure out where to put these expenses so that they become deductions to my taxable income.  Thanks in advance for your help.
