LINE OF CREDIT, NOTES PAYABLE AND LIQUIDITY

On

March 18, 2013,

the Company entered into a

$2,000,000

revolving Line of Credit with The Northern Trust Company ("Line of Credit") guaranteed by Cornelis F. Wit, our then Chief Executive Officer and Director ("Mr. Wit"). Mr. Wit receives

2.0%

interest (approximately

$9,500

per month) on the assets pledged for the Line of Credit. On

December 18, 2013

the Company renewed the Line of Credit and increased the available balance to

$4,000,000.

On

February 3, 2015

the Company renewed the Line of Credit and increased the available balance to

$5,000,000.

On

April 7, 2017

the Company renewed the Line of Credit. The Line of Credit matures on

April 7, 2020 

and carries a variable interest rate based on the prime rate. At

December 31, 2018,

$2,900,000

was outstanding on the Line of Credit at an interest rate of

4.5%.

Our primary sources of working capital are funds from operations and borrowings under our Line of Credit. In the event that the Line of Credit is called for any reason, Mr. Wit has pledged to replace the borrowing capacity under the Line of Credit with a promissory note that utilizes the same maturity date and interest rate as the Line of Credit.

To satisfy our capital requirements, we

may

seek additional financing. There can be

no

assurance that any such funding will be available to us on favorable terms or at all. If adequate funds are

not

available when needed, we

may

be required to delay, scale back or eliminate some or all of our research and product development and marketing programs. If we are successful in obtaining additional financings, the terms of such financings

may

have the effect of diluting or adversely affecting the holdings or the rights of the holders of our common and preferred stock or result in increased interest expense in future periods.

December 31, 2018,

On

February

29,

2016,

the Company issued a promissory note in the principal amount of

$450,000

and warrants to purchase

1,800,000

shares of common stock of the Company at an exercise price of

$0.25

per share with an expiration date of

April 1, 2019

to our then Chief Executive Officer and Director, Cornelis F. Wit (“Mr. Wit”), in exchange for accrued interest in the amount of

$450,000.

The note carries an interest rate of

12%

per annum and has a maturity date of

April 1, 2019.

On

December 5, 2016

Mr. Wit sold

1,000,000

of the warrants to an employee of the Company. On

December 27, 2018,

the Company and Mr. Wit cancelled the remaining outstanding

$400,000

in principal in exchange for the exercise price of

$400,000

for 

1,600,000

warrants of the

2,000,000

warrants with an exercise price of

$0.25

per share that he exercised on that date.

This issuance caused us to calculate and record a derivative liability for the warrant liability. The warrants were valued using the Black Scholes option pricing model. A value of

$325,689

was calculated and allocated to the warrants and recorded as a liability to the issuance of the note payable. As a result of the liability we recorded a discount to the note payable. The carrying amount of the note at the time of issuance was therefore

$124,311.

The warrant liability (discount) will be amortized over the

37

month duration of the note payable. The Company will continue to perform a fair value calculation quarterly on the warrant liability and accordingly the warrant liability is increased or decreased based on the fair value calculation. The resulting increase or decrease is reflected in the statement of operations as an unrealized gain or loss on changes in derivative liabilities.
