EFFECT OF AN EVENT OF DEFAULT. If any Event of Default shall occur, except where otherwise provided in this Agreement or the Related Documents, all commitments and obligations of Lender under this Agreement or the Related Documents or any other agreement immediately will terminate (including any obligation to make further Loan Advances or disbursements), and, at Lender's option, all Indebtedness immediately will become due and payable, all without notice of any kind to Borrower, except that in the case of an Event of Default of the type described in the "Insolvency' subsection above, such acceleration shall be automatic and not optional.

References in the boxes above are for Lender's use only and do not limit the applicability of this document to any particular loan or item. Any item above containing “***” has been omitted due to text length limitations.


Principal Amount: $4,000,000.00	Date of Note: August 16, 2008

PROMISE TO PAY. Costar Video Systems, LLC ("Borrower") promises to pay to Bank of Texas, N.A. ("Lender"), or order, In lawful money of the United States of America, the principal amount of Four Million & 00/100 Dollars ($4,000,000.00) or so much as may be outstanding, together with interest on the unpaid outstanding principal balance of each advance. Interest shall be calculated from the date of each advance until repayment of each advance or maturity, whichever occurs first.

CHOICE OF USURY CEILING AND INTEREST RATE. The interest rate on this Note has been implemented under the "Quarterly Ceiling" as referred to in Section 303.006 of the Texas Finance Code. The terms, including the rate, or index, formula, or provision of law used to compute the rate on the Note, will be subject to revision as to current and future balances, from time to time by notice from Lender in compliance with Section 303.103 of the Texas Finance Code.

PAYMENT. Borrower will pay this loan in one payment of all outstanding principal plus all accrued unpaid interest on August 18, 2009. In addition, Borrower will pay regular monthly payments of all accrued unpaid interest due as of each payment date, beginning September 16, 2008, with all subsequent interest payments to be due on the same day of each month after that. Unless otherwise agreed or required by applicable law, payments will be applied first to any accrued unpaid interest; then to principal; and then to any unpaid collection costs. Borrower will pay Lender at Lender's address shown above or at such other place as Lender may designate in writing. Notwithstanding any other provision of this Note, Lender will not charge interest on any undisbursed loan proceeds. No scheduled payment, whether of principal or interest or both, will be due unless sufficient loan funds have been disbursed by the schedul ed payment date to justify the payment.

VARIABLE INTEREST RATE. The interest rate on this Note is subject to change from time to time based on changes In an index which is the BOKF National Prime Rate, described as the rate of interest set by BOK Financial Corporation, In its sole discretion, on a daily basis as published by BOK Financial Corporation ("BOKF') from time to time (the "Index"). The Index is not necessarily the lowest rate charged by Lender on its loans and is set by Lender In Its sole discretion. If the Index becomes unavailable during the term of this loan, Lender may designate a substitute index after notifying Borrower. Lender will tell Borrower the current Index rate upon Borrower's request. The interest rate change will not occur more often than each day. Borrower understands that Lender may make loans based on other rates as well. The index currently is 5.000% per annum. The Interest rate to be applied prior to maturity to the unpaid principal balance of this Note will be calculated as described in the "INTEREST CALCULATION METHOD" paragraph using a rate equal to the Index, resulting in an initial rate of 5.000% per annum based on a year of 360 days. NOTICE: Under no circumstances will the interest rate on this Note be more than (except for any higher default rate or Post Maturity Rate shown below) the lesser of 18.000% per annum or the maximum rate allowed by applicable law. For purposes of this Note, the "maximum rate allowed by applicable law' means the greater of (A) the maximum rate of Interest permitted under federal or other law applicable to the indebtedness evidenced by this Note, or (B) the "Quarterly Ceiling" as referred to In Section 303.006 of the Texas Finance Code.

INTEREST CALCULATION METHOD. Interest on this Note is computed on a 365/360 basis; that is, by applying the ratio of the Interest rate over a year of 360 days, multiplied by the outstanding principal balance, multiplied by the actual number of days the principal balance is outstanding, unless such calculation would result in a usurious rate, in which case interest shall be calculated on a per diem basis of a year of 365 or 366 days, as the case may be. All interest payable under WS Note is computed using this method.

PREPAYMENT. Borrower agrees that all loan fees and other prepaid finance charges are earned fully as of the date of the loan and will not be subject to refund upon early payment (whether voluntary or as a result of default), except as otherwise required by law. Except for the foregoing, Borrower may pay without penalty all or a portion of the amount owed earlier than It is due. Prepayment In full shall consist of payment of the remaining unpaid principal balance together with all accrued and unpaid interest and all other amounts, costs end expenses for which Borrower is responsible under this Note or any other agreement with Lender pertaining to this loan, and in no event will Borrower ever be required to pay any unearned interest. Early payments will not, unless agreed to by Lender in writing, relieve Borrower of Borrower's obligation to continue to make payments of accrued unpaid interest. Rather, early payments will reduce the principal balance due. Borrower agrees not to send Lender payments marked "paid in full", "without recourse", or similar language. If Borrower sends such a payment, Lender may accept it without losing any of Lender's rights under this Note, and Borrower will remain obligated to pay any further amount owed to Lender. All written communications concerning disputed amounts, including any check or other payment instrument that Indicates that the payment constitutes "payment in full" of the amount owed or that is tendered with other conditions or limitations or as full satisfaction of a disputed amount must be mailed or delivered to: Bank of Texas, N.A., P.O. Box 248818 Oklahoma City, OK 73124-8818.

POST MATURITY RATE. The Post Maturity Rate on this Note is the lesser of (A) the maximum rate allowed by law or (B) 18.000% per annum based on a year of 360 days. Borrower will pay interest on all sums due after final maturity, whether by acceleration or otherwise, at that rate.

Payment Default. Borrower falls to make any payment when due under this Note.
