The Amended Loan Agreement also contains events of default that include, among other things, non-payment defaults, covenant defaults, insolvency defaults, cross-defaults to other indebtedness and material obligations, judgment defaults, inaccuracy of representations and warranties, and a material adverse change default. Any default that is not cured or waived could result in the acceleration of the obligations under the credit facility, an increase in the applicable interest rate under the credit facility to a per annum rate equal to 5.00% above the applicable interest rate, and would permit Pacific Western Bank to exercise remedies with respect to all of the collateral that is securing the credit facility. The Amended Loan Agreement will continue in full force and effect for so long as any obligations remain outstanding thereunder, provided, that, Pacific Western Bank has the right to terminate its obligation to make further advances to us immediately and without notice upon the occurrence and during the continuance of an event of default. We may terminate the formula revolving line or the non-formula revolving line at any time prior to the maturity date, upon two business days written notice to Pacific Western Bank, at which time all then outstanding obligations arising under the Amended Loan Agreement, including any unpaid interest thereon, will accelerate and become immediately due and payable.
