All sums are payable by personal delivery or by mail to Lender at the address listed above, or at such other address as Lender may designate to Borrower. This note is provided pursuant to the Revolving Credit Agreement dated July 30, 2010 as amended by the First Amendment dated January 24, 2011 and the Second Amendment dated February 4, 2011, by and between Xxxxxx and Xxxxxxxx.

1. Interest. The unpaid principal balance under this Revolving Unsecured Promissory Note (“Promissory Note”) shall bear interest from the date hereof at an annual rate equal to the London Interbank Offered Rate (LIBOR) plus six percent (6%) (the “Applicable Rate”). The Applicable Rate shall be adjusted quarterly on the first day of each calendar quarter while any principal balance hereunder remains unpaid, based on the LIBOR in effect on the business day immediately preceding such adjustment date.

2. Payment of Principal and Interest. The principal of this Promissory Note, together with all accrued interest thereon, shall be due and payable on July 30, 2012. Any portion of the principal of this Promissory Note may be prepaid, together with the accrued interest with respect to such principal payment, prior to maturity, without penalty. Any payment made under this Promissory Note shall be applied first to accrued interest and then to principal. Payment of principal and interest shall be made in such coin or currency of the United States of America that, at the time of payment, constitutes legal tender for the payment of public and private debt.

3. Events of Default. The occurrence of any of the following events shall constitute an “Event of Default”:

(a) the failure of Borrower to pay all or any portion of the principal and interest due and payable under this Promissory Note and such failure continues for five (5) business days after the Lender notifies Borrower in writing of such failure;

(b) the filing against Borrower of an involuntary petition or other pleading seeking the entry of a decree or order for relief under the United States Bankruptcy Code or any similar federal or state insolvency or other similar law ordering: (i) the liquidation of Borrower, (ii) a reorganization of Borrower or the business and affairs of Borrower, or (iii) the appointment of a receiver, liquidator, assignee, custodian, trustee or similar official for Borrower or the property of Xxxxxxxx, and the failure to have such petition or other pleading denied or dismissed within thirty (30) days from the date of filing;

(c) the commencement by Borrower of a voluntary case under the United States Bankruptcy Code or any similar federal or state insolvency or other similar law, (ii) the consent by Borrower to the appointment or taking possession by a receiver, liquidator, assignee, trustee, custodian or similar official for Borrower or any of the property of Borrower, or (iii) the making by Borrower of an assignment for the benefit of creditors.

(d) the breach of any term of any of the Loan Documents as defined in that Revolving Credit Agreement of July 30, 2010 by and between Borrower and Lender.

4. Rights and Remedies Upon Default. Upon the occurrence of an Event of Default, the principal and all accrued but unpaid interest due under this Promissory Note shall, at the option of Lender, become immediately due and payable and may be collected forthwith without notice to Borrower, regardless of the stipulated date of maturity and, in that event, Borrower promises to pay, in addition to the unpaid principal and interest hereunder, all costs, including reasonable attorneys’ fees, paralegals’ fees and expenses for any primary, appellate, bankruptcy and post-judgment proceedings, that Xxxxxx may incur or be put to in the collection of such amounts. Any overdue payment of principal or interest due under this Promissory Note shall bear interest from the due date at twelve percent (12%) per annum.

5. Waiver. Borrower hereby waives protest, demand, presentment and notice of dishonor, notice of the maturity, nonpayment, and all requirements necessary to hold it liable as the maker of this Promissory Note, and agrees that this Promissory Note may be extended in whole or in part without limit as to the number of such extensions or the period or periods thereof, and without notice to it and without affecting its liability hereunder. Failure to accelerate the debt in the event of any default hereunder, or other indulgence granted from time to time, shall not be construed as a novation of this Promissory Note or a waiver of the right of Lender to thereafter insist upon strict compliance with the terms of this Promissory Note without previous written notice of such intention being given to Borrower.

6. Compliance With Usury Laws. All agreements between Borrower and Lender are hereby expressly limited so that in no event shall the amount paid or agreed to be paid to Lender for the use, forbearance, or detention of the money loaned under this Promissory Note exceed the maximum amount permissible under the laws of the State of Florida. If, at the time of any interest payment, the payment amount due under this Promissory Note is in excess of the legal limit, the obligation shall be reduced to the legal limit. If Borrower should ever receive, as interest, an amount that exceeds the highest lawful rate, the amount that would be excessive as interest shall be applied to the reduction of the principal amount owing under this Promissory Note, and not to the payment of interest.

7. Waiver of Jury Trial. XXXXXXXX HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED HEREON, OR ARISING OUT OF, UNDER OR IN CONJUNCTION WITH, THIS PROMISSORY NOTE AND ANY OTHER AGREEMENT CONTEMPLATED TO BE EXECUTED IN CONJUNCTION HEREWITH, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER VERBAL OR WRITTEN) OR ACTIONS OF EITHER PARTY.

8. Choice of Law; Venue. The laws of the State of Florida, excluding its choice of law provisions if such laws would result in the application of laws other than the laws of the State of Florida, shall govern any disputes with respect to this Promissory Note, the validity of this Promissory Note, the construction of its terms, and the interpretation of the rights and duties of Xxxxxxxx and Lender hereunder. The forum selected for any proceeding or suit related to a dispute between Borrower and Lender related to this Promissory Note shall be in a federal or state court of competent jurisdiction located in Hillsborough County, Florida. Xxxxxxxx consents to said courts’ personal jurisdiction over it and waives any defense, whether asserted by motion or pleading, that Hillsborough County, Florida is an improper or inconvenient venue.

9. Notice. Any notice, demand or other communication to Borrower that is permitted or required hereunder shall be given in writing, and shall be deemed to have been duly delivered (i) when delivered by personal delivery, (ii) three (3) days after being deposited with the United States Postal Service for mailing by first class mail, postage prepaid, certified mail, with return receipt requested (regardless of whether the return receipt is subsequently received), or (iii) one business day after being deposited with a nationally recognized courier service for overnight delivery; and in each case addressed by Xxxxxx to Borrower at the address for Borrower first listed above, or to such other address as Borrower may notify Lender in writing in conformity with the provisions of this Section.
