3.           Default.  The occurrence of any of the following events shall constitute default under this Note, and the Lender, at his option, exercise any or all rights, powers and remedies afforded under the Note and by law, including the right to declare the unpaid balance of principal and accrued interest on this Note at once mature and payable:

(a)

any part of the Note is not paid when due, whether by lapse of time or acceleration or otherwise.

(b)

any action, suit or proceeding shall be commenced against or affecting Borrower, at law or in equity, or before any governmental authority, which in Lender's judgment, impairs or would impair Lender's ability to collect the Note when due or the enforceability of this Note.

(c)

Borrower shall be in default under or in violation of any law, statute, ordinance, decree, requirement, order, judgment, rule or regulation (or interpretation of any of them) of the United States of America, any State of the United States of America or any political subdivision of any of them, or of any agency, department, commission, board, bureau or court or other tribunal having jurisdiction over any such party or any such party's property.

4            No Delay.  No delay or omission of Lender or any other holder hereof to exercise any power, right or remedy accruing to Lender or any other holder hereof shall impair any such power, right or remedy or shall be construed to be a waiver of the right to exercise any such power, right or remedy.  Lender's right to accelerate this Note for any late payment or Borrower’s failure to timely fulfill its other obligations hereunder shall not be waived or deemed waived by Lender by Lender's having accepted a late payment or late payments in the past or Lender otherwise not accelerating this note or exercising other remedies for Borrower's failure to timely perform its obligations hereunder.  Lender shall not be obligated or be deemed obligated to notify Borrower that it is requiring Borrower to strictly comply with the terms and provisions of this note before accelerating this note and exercising its other remedies hereunder because of Borrower's failure to timely perform its obligations under this Note.

5.           Expenses of Collection.  The Borrower  agrees, subject only to any limitation imposed by applicable law, to pay all expenses, including reasonable attorneys' fees and reasonable legal expenses, incurred by the holder of this Note in endeavoring to collect any amounts payable hereunder which are not paid when due.

7.           Invalidity.  If any provision of this Note is held to be illegal, invalid or unenforceable under present or future laws, the legality, validity and enforceability of the remaining provisions of this Note shall not be affected thereby, and this Note shall be liberally construed so as to carry out the intent of the parties to it.  Each waiver in this Note is subject to the overriding and controlling rule that it shall be effective only if and to the extent that (a) it is not prohibited by applicable law and (b) applicable law neither provides for nor allows any material sanctions to be imposed against Lender for having bargained for and obtained it.
