NOTE 5. BANK DEBT

Union Bank Credit Facility

On February 4, 2011, we entered into a credit facility agreement with Union Bank that provides for the following:

•

A revolving credit line of up to $1.5 million in borrowing availability, under which no amounts have been borrowed;

•

A non-revolving credit line of up to $350,000 in borrowing availability for the purchase of equipment, which expired unused on February 4, 2012; and

•

A term loan of $1,250,000, of which $863,000 was outstanding as of March 31, 2012.

The maximum amount of borrowing under the revolving credit line is the lesser of:

(a)

$1,500,000; or

(b)

the sum of 80% of eligible domestic accounts receivable, plus the lesser of:

(i)

$400,000; or

(ii)

15% of the eligible raw materials and finished goods inventories.

Based on the foregoing, at March 31, 2012 we had the ability to borrow up to approximately $1.4 million on the revolving line of credit.

The revolving credit line's terms require monthly interest payments based on borrowed amounts at a floating interest rate, calculated as Union Bank's Reference Rate plus 0.5% (an aggregate interest rate of 3.75% at March 31, 2012). The line's initial term expires on December 15, 2012, after which it is renewable annually at Union Bank's option. Should Union Bank decide not to renew the line, it must give us a 60-day notice of such decision.

The terms of the $1.25 million term loan, the proceeds of which were used to pay off in full the Wells Fargo term loan described below, require monthly principal payments of $29,762, plus interest over its 42-month term. The term loan bears interest at a floating rate, calculated as Union Bank's Reference Rate plus 0.5% (an aggregate interest rate of 3.75% at March 31, 2012).

All personal property assets of the Company collateralize the outstanding borrowings under the Union Bank credit facility.

The Union Bank credit facility agreement contains financial covenants that require us to comply with minimum quarterly liquidity and annual profitability thresholds, non-financial covenants that include monthly, quarterly and annual reporting requirements, and certain operational restrictions. At March 31, 2012, we were in compliance with these covenants and requirements.

Wells Fargo Bank Credit Facility

From November 2008 until February 4, 2011, we had a credit facility with Wells Fargo Bank consisting of the following:

•

A revolving credit line of up to $1.0 million in borrowing availability, under which no amounts were outstanding during its term; and

•

A five-year term loan with an initial balance of $2.0 million, of which $1.17 million was outstanding at December 31, 2010. On February 4, 2011, the term loan was paid off in full, as discussed further above.

Union Bank Mortgage

In March 2006, we entered into a ten-year mortgage with Union Bank for $1.65 million. The principal balance of the mortgage bore interest at a fixed annual rate of 6.73%. Payments on the mortgage were $11,379 per month (based on a 25-year amortization), with the balance of $1.3 million in principal due on April 1, 2016. The mortgage was collateralized by our Carson City, Nevada, land and building. On September 16, 2010, we paid the remaining $1.5 million balance due on the Union Bank mortgage, fully retiring such indebtedness.
