2.3 Interest on the CONSTRUCTION NOTE. Interest on the CONSTRUCTION NOTE shall accrue at the LIBOR RATE, plus three hundred ten basis points prior to acceleration or maturity, and nine hundred ten basis points in excess of the LIBOR RATE in effect from time to time after maturity, whether by acceleration or otherwise.

2.5 EXPANSION TERM LOANS. The existing balance on the EXPANSION LOAN, as of COMPLETION DATE will be restated and said balance will be paid by three new promissory notes, hereafter called “FIXED RATE NOTE” (which will be the result of fifty {50%} percent of the EXPANSION LOAN), “VARIABLE RATE NOTE”, and “LONG TERM REVOLVING NOTE” in the forms attached hereto as Exhibits “D”, “E”, and “F”, which are by this reference made a part hereof.

b.	next to accrued interest on VARIABLE RATE NOTE;

All unpaid principal and accrued interest under the EXPANSION TERM LOANS shall be due and payable on LOAN TERMINATION DATE, if not sooner paid.

2.6 REVOLVING LOAN. BANK agrees to lend $5,000,000.00 to BORROWER pursuant to this facility. BANK will credit proceeds of this revolving loan (“REVOLVING LOAN”) first to repay the NOTE previously evidencing the REVOLVING LOAN, and thereafter to BORROWER’s deposit account with the BANK, bearing number 110150455. Subject to the terms hereof, the BANK will lend the BORROWER, from time to time until the LOAN TERMINATION DATE, such sums as the BORROWER may request by reasonable same day notice to the BANK, received by the BANK not later than 11:00 A.M. of such day, but which shall not exceed in the aggregate principal amount at any one time outstanding, $5,000,000.00 (the “LOAN COMMITMENT”). The BORROWER may borrow, repay without penalty or premium and reborrow hereunder, from the date of this AGREEMENT until the LOAN TERMINATION DATE, either the full amount of the LOAN COMMITMENT or any lesser sum. It is the intention of the parties that the outstanding balance of the REVOLVING LOAN shall not exceed the BORROWING BASE, and if at any time said balance exceeds the BORROWING BASE, BORROWER shall forthwith pay BANK sufficient funds to reduce the balance of the REVOLVING LOAN until it is in compliance with this requirement.

2.7 THE REVOLVING NOTE. The LOAN COMMITMENT shall be evidenced by a REVOLVING NOTE having stated maturity on the LOAN TERMINATION DATE, in the form attached hereto as Exhibit “C”.

2.9 TERM NOTE C, TERM NOTE D, AND TERM NOTE E. The existing TERM NOTE C, TERM NOTE D, and TERM NOTE E, executed pursuant to the 2003 AGREEMENT constitute OBLIGATIONS, and will be paid by BORROWER according to the following schedule:

     On the first day of each quarter, commencing September 20, 2006, BORROWER shall pay to BANK the scheduled principal payment shown in Schedule I, attached hereto and by this reference

BANK will issue its letters of credit at BORROWER’s request, on BORROWER’s account, pursuant to the BANK’s customary policies and with its standardized documents, in amounts outstanding at no time exceeding $1,000,000.00 in the aggregate. This facility will be reviewed by BANK and is subject to BANK’s annual renewal of the facility.

2.11 Payments and Prepayments. All principal, interest and fees due under this AGREEMENT, the NOTES and the LOAN DOCUMENTS shall be paid in immediately available funds as contracted in this AGREEMENT and no later than the payment due date set forth in the periodic statements mailed to the BORROWER by the BANK. Should a payment come due on a day other than a BANKING DAY, then the payment shall be made no later than the next BANKING DAY and interest shall continue to accrue during the extended period.

     On the occasion of any prepayment of TERM NOTE C or TERM NOTE D, BORROWER will pay to BANK a prepayment fee equal to one (1%) percent of the original principal amount of such NOTE. On the occasion of any prepayment of CONSTRUCTION NOTE, or FIXED RATE NOTE and VARIABLE RATE NOTE, in full, BORROWER will pay to BANK a prepayment fee calculated as follows: If the prepayment occurs during the construction of the PROJECT or within the first three years of the FIXED RATE NOTE or the VARIABLE RATE NOTE, a fee of Four Hundred Sixty-Three Thousand ($463,000.00) shall be paid to BANK.

     The NOTES evidencing the OBLIGATIONS may also include requirements for compensation to the BANK for prepayment of such NOTES evidencing fixed interest rates.

2.12 Fees. At CLOSING, the BORROWER shall pay to the BANK a commitment fee of $231,500.00, which fee BORROWER agrees and acknowledges has been earned by BANK. On September 20, 2006, and the same date in each year thereafter, the BORROWER shall pay to the BANK an Annual Servicing Fee of $20,000.00, which fee BORROWER agrees and acknowledges has been earned by BANK; provided, however, an Annual Servicing Fee shall not be due and payable on the LOAN TERMINATION DATE and the BANK shall refund the Annual Servicing Fee on a pro rata basis if the Loan Termination Date occurs other than on an anniversary of the COMPLETION DATE. The Annual Servicing Fee set forth in this paragraph 2.12 replaces any obligation of BORROWER to pay a servicing fee pursuant to the 2003 AGREEMENT.

     BORROWER agrees to pay BANK an unused commitment fee on the unused portion of the REVOLVING LOAN and of the LONG TERM REVOLVING LOAN, calculated and payable on a quarterly basis in arrears. In the case of the LONG TERM REVOLVING LOAN, such unused commitment fee shall only be calculated and due following COMPLETION DATE. Such unused

- 11 -

commitment fee shall vary, depending on BORROWER’s ratio of INDEBTEDNESS to NET WORTH during the quarter being measured.

2.13 Appraisal. The BANK will obtain, at BORROWER’s expense, an appraisal from Natwick Associates Appraisal Services, Inc. of the PROJECT and PROPERTY providing values obtained by use of the cost approach, the income approach and the replacement cost approach. If such appraisal shows that the outstanding EXPANSION LOAN amount at that time exceeds the value of the PROJECT and PROPERTY as determined by the appraisal, using the replacement cost approach, then the BORROWER shall, within thirty (30) days of notice by the BANK and without penalty or premium, pay the difference between the outstanding EXPANSION LOAN amount and the appraised value amount of the PROJECT and PROPERTY as determined by such appraisal, and no further advances shall be made on the EXPANSION LOAN thereafter until such time as the appraised value of the PROJECT and PROPERTY exceeds the EXPANSION LOAN amount.

2.14 Incentive Pricing. The interest rate applicable to certain of the NOTES may be subject to reduction based on the business results of BORROWER. In the event that BORROWER maintains the ratios set forth in this section 2.14, as measured at the end of each calendar quarter, the interest rate for such NOTES containing an Incentive Pricing feature will be reduced accordingly.
