(d) Credit Facility

The Company has a revolving line of credit agreement with Western Alliance Bank, which provides for a $15.0 million revolving secured credit facility maturing on June 30, 2018. Amounts outstanding under the line of credit bear interest at the prime rate plus 0.75% with accrued interest payable on a monthly basis and outstanding and unpaid principal due upon maturity. Western Alliance Bank maintains a security interest in substantially all of the Company’s tangible and intangible assets, excluding intellectual property, to secure any outstanding amounts under the loan agreement. The loan agreement contains customary events of default, conditions to borrowing and covenants, including restrictions on the Company’s ability to dispose of assets, make acquisitions, incur debt, incur liens and make distributions and dividends to stockholders. The loan agreement also includes a financial covenant related to the Company’s recurring revenue renewal rate. During the continuance of an event of default, Western Alliance Bank may accelerate amounts outstanding, terminate the credit facility and foreclose on the collateral.

In June 2018 the Company extended the line of credit with the same terms as above except for a change in maturity date to September 28, 2018.

As of June 30, 2018, no amounts had been drawn under the credit facility.
