2.Definitions. Any capitalized terms used but not otherwise defined herein shall have the meanings ascribed thereto in the Agreement.

3.Interpretations. In this Amendment, unless a clear contrary intention appears, (a) the words “herein,” “hereof” and “hereunder” and other words of similar import refer to this Amendment as a whole and not to any particular Article, Section or other subdivision; (b) reference to any Article or Section, means such Article or Section hereof; and (c) the word “including” (and with correlative meaning “include”) means including, without limiting the generality of any description preceding such terms.

ARTICLE II

AGREEMENT

The parties hereby mutually agree to the following terms as reflected below.

2.1Term.  Notwithstanding the provision contained in Section 2.1 of the Agreement that the “Agreement may be extended for an additional period at the end of the Initial Term (“Renewal Term”) upon the mutual agreement of the parties entered into at least 30 days prior to the end of the Initial Term”, the Parties do hereby mutually agree to waive and delete the “30 days prior” requirement and do hereby mutually agree that Section 2.1 of the Agreement shall, effective at the end of the Initial Term and forever thereafter be supersede and replaced with the following:

“The term of this Agreement will commence on the Effective date of this Agreement and end on March 31, 2013 (the “Initial Term”); however, the Agreement is hereby extended for (a) an additional two (2) year period commencing April 1, 2013 and ending on March 31, 2015, and (b) for such other subsequent periods of time as from time to time may be mutually agreed between the Parties prior to the end of any such respective extended term.”

2.2Compensation.

Base Salary.  During the Initial Term, the Key Employee has received one or more increases in Base Salary and therefore it is appropriate to reflect said increase(s) in the Base Salary provision of the Agreement and, as a result, the Parties do hereby mutually agree that Section 2.3 (a) of the Agreement shall, effective at the end of the Initial Term and forever thereafter be supersede and replaced with the following:

“(a) Base Salary.  Key Employee will receive an initial Base Salary at the rate of Two Hundred Seventy-Four Thousand, Nine Hundred Ninety-Nine Dollars and Ninety-Two cents ($274,999.92) per annum payable in periodic installments in accordance with the Company’s normal payroll practices and procedures, which base salary may be increased (but not decreased) by the Company from time to time.”
