[1] | Revolving Line of Credit Amounts advanced under the Revolving Line bear interest at an annual rate equal to the greater of (a) 4.25% or (b) the Wall Street Journal prime rate plus 1%. Interest is payable on a monthly basis, with the balance payable at the maturity of the Revolving Line. The current interest rate is 4.25%. Under the Amendment, amounts advanced under the Revolving Line bear interest at an annual rate equal to the greater of (a) 6.25% or (b) the Wall Street Journal prime rate plus 3% . Under the Loan Agreement, we paid the Lenders an upfront fee of $20,000, and will pay the Lenders an additional commitment fee of $20,000 on each anniversary of the Effective Date during the term of the Revolving Line. In addition, a fee of 0.5% per year is payable quarterly on the unused portion of the Revolving Line. The Revolving Line matures on September 1, 2016.
[2] | Term Loan We received $4.0 million under the Term Loan on the Effective Date. We are required to make interest-only payments under the Term Loan through December 31, 2013 and principal and interest payments on a monthly basis, beginning on January 1, 2014, over 33 months using a straight-line amortization rate. Interest under the Term Loan will accrue at the annual rate of one month LIBOR plus 6.1%, subject to a LIBOR floor of 3%. The current interest rate is 9.1%.We paid the Lenders an upfront fee of $40,000 for the Term Loan, and will pay the Lenders an additional final payment of $120,000 at maturity or prepayment of the Term Loan. In addition, if we repay the Term Loan prior to maturity, we will pay the Lenders a prepayment penalty of 5% of the total outstanding balance under the Term Loan if the prepayment occurs within one year after the Effective Date, 2.5% of the total outstanding balance under the Term Loan if the prepayment occurs between one and two years after the Effective Date, and 1% of the total outstanding balance under the Term Loan if the prepayment occurs thereafter.Additional TermsThe Loan Agreement contains affirmative and negative covenants. Under the Term Loan, we are required to maintain a minimum liquidity ratio and achieve a minimum amount of revenue, and we also agreed not to (i) pledge or otherwise encumber our assets other than to the Lenders, (ii) enter into additional borrowings or guarantees, (iii) repurchase our capital stock, or (iv) enter into certain mergers or acquisitions without the Lenders' consent. Additionally, the Loan Agreement contains a subjective acceleration clause at the discretion of the Lenders.To secure the repayment of any amounts borrowed under the Revolving Line and the Term Loan, we granted the Lenders a security interest in all of our assets. The occurrence of an event of default under the Loan Agreement could result in the acceleration of our obligations under the Loan Agreement and would increase the applicable interest rate under the Revolving Line or the Term Loan (or both) by 5%, and permit the Lenders to exercise remedies with respect to the collateral under the Loan Agreement.
[3] | The First Note was a three year senior secured promissory note payable to PGxHealth, LLC entered into on December 29, 2010 in conjunction with our acquisition of the FAMILION family of genetic tests. Interest was payable at 10% per year with quarterly interest payments through March 29, 2012. Thereafter, quarterly installments include both principal and interest through December 30, 2013. The First Note was paid in full on March 13, 2013.
