Payment of Accrued Wages

With my consent, during several periods over the past two years, my employer, an Indiana restaurant corporation, accrued a substantial portion of my agreed salary because it had cash flow problems. The accrued wages were to be paid to me when cash flow permitted, or upon termination of my employment. I have been terminated. I was in charge of marketing and advertising, and the company indicated that its cash position did not allow continued investments in those areas. Today, the company's controller advised that $34,153.96 is accrued on the books as unpaid wages due to me, but that the she has no funds with which to pay me. The company is in a precarious financial situation and may be sold or bankrupt shortly, but it is making some payments to suppliers and creditors, and meeting current payroll. I have written a demand letter. What else should I do?
