This Promissory Note (this “Note”) is the Promissory Note described in that certain Loan Agreement dated of even date herewith between Borrower and Lender (the “Loan Agreement”).

a.           Absent the occurrence and continuation of an Event of Default (defined below) or until receipt of written notice from Lender of Lender’s termination of the Loan in accordance with section 1.1b below, Borrower may request advances and re-advances of the Loan, in accordance with the Loan Agreement.

b.           Unless earlier accelerated, all principal, interest, costs and fees under this Note shall be due and payable in full on the date that is thirty-six (36) months following the date hereof (such date being hereinafter referred to as the “Maturity Date”).

1.2.         Interest Rate. Interest shall accrue on the principal balance outstanding from time to time on this Note at a fixed interest rate at all times equal to five percent (5%) per annum. Interest shall be calculated on the basis of 360 days per year factor applied to the actual days on which there exists a principal balance outstanding under this Note. Interest shall be charged on a per diem basis.

a.           Beginning on the date that is one (1) month following disbursement of any amounts, and continuing on the same day of each consecutive month thereafter until the Maturity Date, Borrower shall make monthly payments of accrued interest only, in arrears, on the then-outstanding principal balance of this Note.

b.           On the Maturity Date, Borrower shall pay in full all sums due under this Note, including principal, all accrued and unpaid interest, and any applicable charges and fees.

All payments hereon shall be payable in lawful money of the United States and in immediately available funds. All payments received shall be applied to this Note as follows: (i) first, to payment of accrued and unpaid interest, if any; (ii) second, to payment of any principal then due, if any; (iii) third to late charges, if any; (iv) fourth, to attorney’s fees and costs of collection; and (v) fifth, to reduce the outstanding principal balance of this Note until such principal shall have been fully repaid. All payments hereunder shall be made without offset, demand, counterclaim, deduction, abatement, defense, or recoupment, each of which Borrower hereby waives.

1.4.         Late Charge. If any payment due under this Note is not received by Lender within ten (10) calendar days of its due date, Borrower shall pay a late charge equal to five percent (5%) of the amount of such payment.

1.5.         Prepayment. This Note may be prepaid, in whole or in part, at any time without premium or penalty.

2.1.         Events of Default. Each of the following shall constitute an event of default under this Note (each an “Event of Default”):

a.           A default in the payment of any sum within ten (10) days of when due under this Note.

b.           A default in the performance of any of the covenants, conditions or terms of this Note, the Loan Agreement or any other agreement or document executed by Borrower for the benefit of Lender or any holder in connection with the Loan (collectively, the “Loan Documents”) beyond any applicable notice and cure periods.

2.2.         Remedies. Upon the occurrence and continuation of an Event of Default, in addition to all other rights and remedies available to Lender under the Loan Documents and applicable law, Lender shall have the following rights and remedies:

a.           Acceleration. Lender, in Lender’s sole discretion and without notice or demand, may declare the entire principal balance outstanding under this Note, plus accrued interest and all other sums owed in connection therewith, immediately due and payable.

b.           Default Interest Rate. Lender, in Lender’s sole discretion and without notice or demand, may raise the rate of interest accruing on the principal balance outstanding hereunder by five (5) percentage points above the rate of interest otherwise applicable, independent of whether Lender elects to accelerate the principal balance outstanding under this Note.

2.3.         Expenses of Collection and Attorneys’ Fees. If this Note is referred to an attorney for collection, whether or not judgment has been confessed or suit has been filed, Borrower shall pay all of Lender’s costs, fees and expenses, including reasonable attorneys’ fees, resulting from such referral.

3.1.         Assignability. This Note may be assigned by Lender or any holder at any time or from time to time. This Note shall inure to the benefit of and be enforceable by Lender and Lender’s successors and assigns and any other person to whom Lender or any holder may grant an interest in Borrower’s obligations under this Note, and shall be binding and enforceable against Borrower and Borrower’s personal representatives, successors and assigns.

3.2.         Negotiable Instrument. Borrower agrees that this Note shall be deemed negotiable instruments even if this Note would not qualify under applicable law, absent this Section, as a negotiable instrument.

3.4.         Unconditional Obligations. Borrower’s obligations under this Note shall be the absolute and unconditional duty and obligation of Borrower and shall be independent of any rights of set-off, recoupment or counterclaim which Borrower might otherwise have against the holder of this Note, and Borrower shall pay absolutely the payments of principal, interest, fees and expenses required under this Note, free of any deductions and without abatement, diminution or set-off.

3.8.         Set-off. In addition to all liens upon, and rights of set-off against the money, credit, stocks, bonds and/or securities or other property of any nature whatsoever of Borrower given to the Lender by law, the Lender shall have a lien upon and a right of set-off against all money, credit, stocks, bonds and/or securities and other property of any nature whatsoever of Borrower now or hereafter on deposit with, or held by, or in the possession of or on account with the Lender (excluding accounts maintained by Borrower with Lender for the benefit of Borrower’s customers, any joint accounts or other business accounts), whether held in a general or special account or deposit, or for safe-keeping or otherwise; and every such lien and right of set-off may be exercised without demand upon or notice to Borrower, upon an Event of Default under this Note or any of the Loan Documents. No lien or right of set-off shall be deemed to have been waived by any act or conduct on the part of the Lender, or by any neglect to exercise such right of set-off or to enforce such lien, or by any delay in so doing, and every right of set-off and lien shall continue in full force and effect until such right of set-off or lien is specifically waived or released by an instrument in writing executed by the Lender.

3.9.         Partial Invalidity. In the event any one or more of the provisions contained in this Note or in any other of the Loan Documents shall for any reason be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provision of this Note or of any other of the Loan Documents, but this Note and all other of the Loan Documents shall be construed as if such invalid, illegal or unenforceable provision had never been contained herein or therein.
