5. Interest. Interest shall accrue on the outstanding principal balance at a rate of Seven Percent (7%) per annum. Notwithstanding the foregoing, upon an Event of Default (as defined below), this Note shall bear interest on and after the date of such Event of Default pursuant to Section 7.b below.

6. Application of Payments. All payments made hereunder shall be applied first to accrued interest, and then to principal or in such other order or proportion as the Payee of this Note may elect.

7. Default:

a. Each of the following events shall constitute an “Event of Default”:

i. The Payor’s failure to pay to the Payee any of the Obligations when and as due under this Note, if such failure continues for a period of at least five (5) Business Days;

ii. The Payor: (1) applies for or consents to the appointment of a receiver, trustee, custodian or liquidator of it or any of its property, (2) files a voluntary petition in bankruptcy; (3) files an answer seeking reorganization or an arrangement with creditors; (4) otherwise seeks to take advantage of any bankruptcy, reorganization, insolvency, readjustment of debt, dissolution, liquidation or other similar laws or statutes; (5) files any answer admitting the material allegations of a petition filed against it in any proceeding under any such laws identified in subsection 7.a.ii(4), or (6) makes a general assignment for the benefit of its creditors;

iii.

iv. There is a Change of Control of the Payor.

b. Default Interest. Upon an Event of Default, and unless and until cured, the rate of interest accruing on the unpaid principal balance shall be Nine Percent (9%) per annum, independent of whether the Payee of this Note elects to accelerate the unpaid principal balance as a result of such default.

c. Remedies on Event of Default. Upon an Event of Default and at any time thereafter during the continuance of such Event of Default, at the election of the Payee, the Obligations shall immediately become due and payable, without notice, presentment, demand, or protest, all of which are hereby expressly waived. In case any one or more Events of Default shall occur and be continuing and acceleration of this Note shall have occurred, the Payee may, inter alia, proceed to protect and enforce its rights by an action at law, suit in equity or other appropriate proceeding, whether for the specific performance of any agreement contained in this Note, or for an injunction against a violation of any of the terms hereof or thereof or in and of the exercise of any power granted hereby or thereby or by law.
