     5. Events of Default and Remedies. The entire unpaid principal balance of and all accrued interest on this Note shall immediately become due and payable, without notice or demand which are hereby waived, upon the occurrence of any one or more of the following events of default (individually or collectively, herein called a “Default”):

     (a) The failure or refusal of Borrower to pay all or any part of the principal of or accrued interest on this Note as and when same becomes due and payable in accordance with the terms hereof; or

     (b) Borrower shall: (i) become insolvent within the meaning of the Bankruptcy Code of the United States, as amended, (ii) admit in writing its inability to pay or otherwise fail to pay its or his or her debts generally as they become due, (iii) voluntarily seek consent to, or acquiesce in the benefit or benefits of any Debtor Relief Law, or (iv) be made the subject of any proceeding provided for by any Debtor Relief Law that could suspend or otherwise affect any of the rights of the holder hereof.

     (c) The nonpayment when due of any material indebtedness owed by Borrower, or the occurrence of any event under any document or instrument evidencing, securing, or executed in connection with any such indebtedness which could give the holder thereof the right to declare such indebtedness or any part thereof due prior to its scheduled maturity; or

     (d) The discovery by the holder hereof that any statement, representation, or warranty made by Borrower in any writing, document, or instrument ever delivered to the holder hereof in connection herewith was at the time made false, misleading, or erroneous in any material respect.

     Upon the occurrence of a Default, the holder of this Note may: (a) offset against this Note any sum or sums owed by the holder hereof to Borrower and (b) proceed to protect and enforce its rights either by suit in equity and/or by action at law, or by other appropriate proceedings, whether for the specific performance of any covenant or agreement contained in this Note or any document or instrument executed and delivered by Borrower in connection with this Note or in aid of the exercise of any power or right granted by this Note or any document or instrument executed and delivered by Borrower in connection with this Note or to enforce any other legal or equitable right of the holder of this Note.

     6. Cumulative Rights. No delay on the part of the holder of this Note in the exercise of any power or right under this Note, or under any document or instrument executed in connection herewith, shall operate as a waiver thereof, nor shall a single or partial exercise of any other power or right. Enforcement by the holder of this Note of any security for the payment hereof shall not constitute an election by it of remedies so as to preclude the exercise of any other remedy available to it.

     7. Waiver.

     8. Attorneys’ Fees and Costs. In the event that a Default shall occur, and in the event that thereafter this Note is placed in the hands of an attorney for collection, or in the event this Note is collected in whole or in part through legal proceedings of any nature, then and in any such case Borrower promises to pay all costs of collection, including, but not limited to, reasonable attorneys’ fees incurred by the holder hereof on account of such collection, whether or not suit is filed.

Any notice or demand given hereunder by the holder shall be deemed to have been given and received (a) when actually received by Borrower, if delivered in person or by courier or messenger, or (b) two (2) Business Days (as hereinafter defined) after a letter containing such notice, certified or registered, with postage prepaid, addressed to Borrower, is deposited in the United States Mail. The address of Borrower is 1227 South Patrick Drive, Building 2A, Satellite Beach, Florida 32937 or such other address as Borrower shall advise the holder hereof by certified or registered letter.

     10. Governing Law. The laws of New York shall govern the construction, validity, enforcement and interpretation of this Note, except to the extent federal laws otherwise govern the validity, construction, enforcement and interpretation hereof.

     11. Headings. The headings of the sections of this Note are inserted for convenience only and shall not be deemed to constitute a part hereof.

     12. Successors and Assigns. All of the covenants, stipulations, promises and agreements contained in this Note by or on behalf of Borrower shall bind its successors and assigns, whether so expressed or not; provided, that Borrower may not, without the prior written consent of the holder hereof, assign any rights, duties, or obligations under this Note.

     13. Maximum Interest Rate. Regardless of any provision contained herein, or in any other document executed in connection herewith, the holder hereof shall never be entitled to receive, collect or apply, as interest hereon, any amount in excess of the maximum rate of interest permitted to be charged from time to time by applicable law, and in the event the holder hereof ever receives, collects or applies, as interest, any such excess, such amount which would be excessive interest shall be deemed a partial prepayment of the principal hereof and treated hereunder as such; and, if the principal hereof is paid in full, any remaining excess shall forthwith be paid to Borrower. In determining whether or not the interest paid or payable, under any specified contingency, exceeds the highest lawful rate, Borrower and the holder hereof shall, to the maximum extent permitted under applicable law, (a) characterize any nonprincipal payment as an expense, fee, or premium rather than as interest, (b) exclude voluntary prepayments and the effects thereof, and (c) spread the total amount of interest throughout the entire contemplated term hereof; provided, that if the indebtedness evidenced hereby is paid and performed in full prior to the end of the full contemplated term thereof, and if the interest received for the actual period of existence thereof exceeds the maximum lawful rate, the holder hereof shall refund to Borrower the amount of such excess or credit the amount of such excess against the principal hereof, and in such event, the holder hereof shall not be subject to any penalties provided by any laws for contracting for, charging, or receiving interest in excess of the maximum lawful rate.

     14. Business Day; Payments. As used herein, (a) “Business Day” means any day other than Saturday, Sunday or other day on which the Federal Reserve Bank of New York is closed and (b) “Nonbusiness Day” means every day that is not a Business Day. The principal of, or accrued interest on, this Note shall be due and payable in lawful money of the United States of America, in Andover, Massachusetts at the office of Lender, 3000 Minuteman Road, Andover, Massachusetts 01810 in funds which are or will be available for immediate use by Lender at such office at or before 12:00 p.m., Eastern time (daylight or standard, as applicable) on the day payment hereof is due. In any case where a payment of principal or interest hereon is due on a Nonbusiness Day, Borrower shall be entitled to delay such payment until the next succeeding Business Day, but interest shall continue to accrue until the payment is, in fact, made.

     15. Offering. Borrower will use its commercially reasonable efforts to conduct a rights offering (the “Offering”) as soon as is reasonably practical, which Offering shall consist of the offering of approximately 13,000,000 Units (as hereinafter defined, which number of Units excludes the number of Units that may be acquired pursuant to this Note) at a price of $1.006 per Unit. Each unit (a “Unit”) will consist of one share (a “Series D Preferred Share”) of Borrower’s newly designated Series D Non-Convertible Preferred Stock, which Preferred Shares shall have the designations, powers, preferences and rights set forth in the form of Certificate of Designation attached hereto as Exhibit A (the “Series D Certificate of Designation”), and that portion of a Warrant representing the right to purchase one share of Borrower’s common stock for $6.00 per share, which Warrant shall be substantially in the form of Exhibit B attached hereto (the “Warrant”). Borrower will use its commercially reasonable efforts to cause the Series D Certificate of Designation to be filed with the Delaware Secretary of State in substantially the form attached hereto as Exhibit A as soon as is reasonably practical.

     16. Automatic Conversion; Purchase Option.

     (a) If: (i) the registration statement for the Offering is declared effective by the Securities and Exchange Commission prior to the Maturity Date, or (ii) Pegasus Partners IV, L.P. (“Pegasus IV”) voluntarily converts the outstanding principal and interest outstanding under that certain Convertible Note Agreement, dated as of August 28, 2009 (the “Pegasus Note”), by and between Pegasus IV and Borrower (the “Pegasus Conversion”) into a number of Units equal to one Unit for each $1.006 of the then outstanding principal and interest under the Pegasus Note, then Lender shall be deemed to have converted all of the then outstanding principal balance and accrued and unpaid interest of this Note (the “Convertible Debt”), into a number of Units equal to one Unit for each $1.006 of Convertible Debt (the “Automatic Conversion”). Notwithstanding anything herein to the contrary, Lender agrees and acknowledges that any Warrants issued to Lender pursuant to this Note shall be in the form of Exhibit B attached hereto; provided, that the exercise price of such Warrants shall be equal to $12.00 per share.

     (b) The Automatic Conversion shall be deemed to occur on the earlier of: (i) the date the Offering is consummated or (ii) the first Business Day immediately following the date on which Borrower provides Lender with written notice that the Pegasus Conversion has occurred (in either case, the “Effective Date”). The Automatic Conversion shall constitute a binding agreement between Lender and Borrower, in which Lender shall be deemed, without further action on its part, to subscribe for the number of Units it is entitled to receive upon such conversion (which number of Units shall be reduced by the number of Units, if any, Lender receives in accordance with paragraph 0 hereof), and in payment and satisfaction of such subscription, to release Borrower from all liability hereon in respect of the repayment of principal and/or accrued and unpaid interest hereof being converted.

     (c) Borrower shall not be required to issue fractions of Units upon conversion of this Note (or portion thereof). If any fractional interest in a Unit would be delivered upon the conversion of this Note, Borrower shall purchase such fractional interest for an amount in cash equal to $1.006 multiplied by the amount of such fractional interest.

     (e) As soon as practicable after the Effective Date, and in any event, within five (5) Business Days thereafter, Borrower shall issue and deliver to the Lender: (i) a certificate or certificates for the number of Series D Preferred Shares and a Warrant or Warrants issuable upon the conversion of this Note in accordance with the provisions hereof, and (ii) a check or cash in respect of any fraction of a Unit.

     17. Optional Conversion. Paragraph 0 notwithstanding, at any time after the Series D Certificate of Designation is filed and becomes effective, Lender may, at its option, convert all or a portion of the Convertible Debt into a number of Units equal to one Unit for each $1.006 of Convertible Debt (with such conversion first being applied to the portion of Convertible Debt consisting of accrued interest and then being applied to the portion of Convertible Debt consisting of principal) (the “Optional Conversion”). Borrower shall not be required to issue fractions of Units pursuant to the Optional Conversion. If any fractional interest in a Unit would be delivered pursuant to the Optional Conversion, Borrower shall purchase such fractional interest for an amount in cash equal to $1.006 multiplied by the amount of such fractional interest. In the event that (i) Lender exercises its option pursuant to the Optional Conversion prior to the record date of the Offering or (i) Lender is forced to convert all or a portion of the Convertible Debt as a result of the Pegasus Conversion prior to the record date of the Offering, Lender shall not receive any rights in the Offering with respect to the securities of Borrower underlying the Units issued to Lender pursuant to such conversion. Conversion pursuant to

this paragraph 0 shall release Borrower from liability to the extent of the repayment of principal and/or accrued and unpaid interest being converted upon payment in satisfaction of the subscription for the number of Units Lender is entitled to receive pursuant to such conversion.

     18. Legends. Each Series D Preferred Share issuable upon conversion of this Note shall bear the legend set forth below:
