Loan facility, borrowing capacity, description						On May 17, 2012, the agreement was amended and restated. The amended and restated documents reduced the interest rate to prime plus 6%, subject to a minimum of 9.25% and also not less than $8,000 per month. The loan facility allows borrowing of 90% of eligible domestic receivables. In addition, the loan facility now allows borrowing of 90% of eligible foreign receivables to a maximum of $500,000 and 25% of eligible inventory to a maximum of 20% of the amount available on receivables. The total credit line remains at $3,500,000

On December 18, 2012, the agreement was amended in exchange for a fee of $7,500 to reduce the Tangible Net Worth covenant to $1,300,000. However, if the Tangible Net Worth falls below $2,000,000, the amount available to borrow on inventory will be capped at $250,000 reduced from $500,000.
Tangible net worth							1,636,000

Liquidity disclosure	Management believes that the aggregate $3,500,000 available under this facility combined with current projected losses will not be sufficient to meet its current obligations and the Company will need to raise capital through borrowings or sales of equity securities. There can be no assurance that the Company will be able to obtain additional borrowings or complete a sale of equity securities.
