3. Debt

In June 2012, the Company entered into a $3 million loan and security agreement with Silicon Valley Bank (“SVB”), collateralized by the Company’s personal property. The agreement also contained non-financial covenants. By January 2013, the Company had been advanced the entire $3 million. Interest on advances under the agreement was at a fixed interest rate equal to 4.50%. Advances under the loan and security agreement had an interest-only period through December 31, 2013, and had a 24-month payback period that commenced in January 2014. On May 23, 2014, the Company repaid the outstanding principal and accrued interest of approximately $2.4 million to SVB. In addition, the Company expensed approximately $38,000 of unamortized debt discount costs upon the repayment of the loan. With such payoff, the SVB loan agreement and the documents entered into in connection therewith were deemed to be terminated. SVB’s security interest in substantially all of the Company’s assets was also terminated.

On May 28, 2014 (the “closing date”), the Company entered into a loan and security agreement (the “credit facility”) with Square 1 Bank (“Square 1”), pursuant to which Square 1 agreed to make term loans available to the Company for general corporate and working capital purposes and for capital expenditures, in a principal amount of up to $4.5 million.

In December 2014, the Company drew down the entire $4.5 million. The credit facility bears interest at a fixed annual rate of 5.50%. The Company is required to make interest-only payments through November 28, 2015 on the credit facility. The outstanding principal balance plus interest will begin amortizing at the end of the interest-only period, with monthly payments of principal and interest being made by the Company to Square 1 in consecutive monthly installments following November 28, 2015 until the credit facility matures on November 28, 2017. At the Company’s option, it may prepay the outstanding principal balance of the credit facility before November 28, 2017 without penalty or premium.

The credit facility includes affirmative and negative covenants applicable to the Company and any subsidiaries it creates in the future. The affirmative covenants include, among others, covenants requiring the Company to maintain its legal existence and governmental approvals, deliver certain financial reports, maintain insurance coverage and meet certain covenants with respect to enrollment and results of its EVK-001 Phase 3 trial. After the Company receives positive results from the Phase 3 trial, if at all, it must either maintain a ratio of its cash at Square 1 to its cash burn over the preceding month of at least 3.00 to 1.00, or it must deliver evidence of a forthcoming financing or strategic partnership arrangement to Square 1, in each case in an amount satisfactory to Square 1. The negative covenants include, among others, restrictions on the Company’s transferring collateral, incurring additional indebtedness, engaging in mergers or acquisitions, paying dividends or making other distributions, making investments, creating liens and selling assets, in each case subject to certain exceptions.

The credit facility also includes events of default, the occurrence and continuation of which provide Square 1 with the right to exercise remedies against the Company and the collateral securing the term loans under the credit facility, including foreclosure against the Company’s properties securing the credit facilities, including its cash. These events of default include, among other things, the Company’s failure to pay any amounts due under the credit facility, a breach of covenants under the credit facility, the Company’s insolvency, a material adverse change, the occurrence of any default under certain other indebtedness in an amount greater than $400,000 and a final judgment against the Company in an amount greater than $400,000.

In connection with the funding of the term loan, the Company issued to Square 1 a warrant to purchase 22,881 shares of the Company’s common stock at an exercise price of $5.90 per share, the closing price of the Company’s common stock on the day of funding of the credit facility. The warrant expires ten years from its date of issuance. If the warrant has not been exercised prior to its expiration date, it will be deemed to automatically convert by “cashless” conversion. In the event that the Company is acquired, the warrant will be exercisable or deemed automatically converted, which shall be determined based upon whether the Company’s successor assumes the obligations of the warrant.

The estimated fair value of the warrant issued to Square 1 was determined on the date of issuance using the Black-Scholes option-pricing valuation model with the following assumptions:

Risk free interest rate		2.17%
Expected warrant term	10 Years
Expected volatility of common stock		77.19%
Expected dividend yield		0.00%

The value determined for the warrant of $108,122 has been recorded as a debt discount, as well as to equity. The debt discount will be amortized to interest expense over the remaining term of the loan.

The Company incurred approximately $83,000 of loan origination costs related to this credit facility. Such costs have been capitalized and are being amortized to interest expense over the 42 month term of the credit facility.

Future maturities of long-term debt and interest payments under the credit facility as of December 31, 2014 are set forth below:

2015		436,375
2016		2,433,505
2017		2,119,935
Total minimum payments		4,989,815
Less amounts representing interest		(489,815	)
Gross balance of outstanding debt	$	4,500,000
Less debt discount ⁽¹⁾		(108,122	)
Total carrying value	$	4,391,878

Total carrying value, long-term portion	$	4,241,448

Total interest incurred under the loan and security agreements for the years ended December 31, 2014 and 2013 (excluding amortization of debt discount and loan origination costs) was $47,165 and $136,625, respectively.
