Maximum Percentage. Notwithstanding anything to the contrary set forth herein, the Company shall not effect any conversion of Preferred Stock issued under the Plan, and no Participant shall have the right to convert any Preferred Stock, to the extent that after giving effect to such conversion, the beneficial owner of such shares (together with such Participant's affiliates) would have acquired, through conversion of such Preferred Stock or otherwise, beneficial ownership of a number of shares of Common Stock that exceeds 9.99% (the "Maximum Percentage") of the number of shares of Common Stock outstanding immediately after giving effect to such conversion. The Company shall not give effect to any voting rights of such Preferred Stock, and any Participant shall not have the right to exercise voting rights with respect to any Preferred Stock pursuant hereto, to the extent that giving effect to such voting rights would result in such Participant (together with its affiliates) being deemed to beneficially own in excess of the Maximum Percentage of the number of shares of Common Stock outstanding immediately after giving effect to such exercise, assuming such exercise as being equivalent to conversion. For purposes of the foregoing, the number of shares of Common Stock beneficially owned by a Participant and its affiliates shall include the number of shares of Common Stock issuable upon conversion of the Preferred Stock with respect to which the determination of such sentence is being made, but shall exclude the number of shares of Common Stock which would be issuable upon # conversion of the remaining, nonconverted shares of Preferred Stock beneficially owned by such Participant or any of its affiliates and # exercise or conversion of the unexercised or unconverted portion of any other securities of the Company (including, without limitation, any notes or warrants) subject to a limitation on conversion or exercise analogous to the limitation contained in this [Section 6B(g)] beneficially owned by such Participant or any of its affiliates. Except as set forth in the preceding sentence, for purposes of this [Section 6B(g)], beneficial ownership shall be calculated in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended. For purposes of this [Section 6B(g)], in determining the number of outstanding shares of Common Stock, a Participant may rely on the number of outstanding shares of Common Stock as reflected in # the Company's most recent Form 10-K, Form 10-Q, or Form 8-K, as the case may be, # a more recent public announcement by the Company, or # any other notice by the Company or its transfer agent setting forth the number of shares of Common Stock outstanding. For any reason at any time, upon the written request of any Participant, the Company shall within one (1) business day following the receipt of such notice, confirm orally and in writing to any such Participant the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the Company, including the Preferred Stock, by such Holder and its affiliates since the date as of which such number of outstanding shares of Common Stock was reported. By written notice to the Company, the Participant may from time to time increase or decrease the Maximum Percentage to any other percentage not in excess of 9.99% specified in such notice; provided, that # any such increase will not be effective until the sixty-first (61st) day after such notice is delivered to the Company, and # any such increase or decrease will apply only to the Holder providing such written notice and not to any other Holder. In the event that the Company cannot pay any portion of any dividend, distribution, grant or issuance hereunder to a Participant solely by reason of this [Section 6B(g)] (such shares, the "Limited Shares"), notwithstanding anything to the contrary contained herein, the Company shall not be required to pay cash in lieu of the payment that otherwise would have been made in such Limited Shares, but shall hold any such Limited Shares in abeyance for such Holder until such time, if ever, that the delivery of such Limited Shares shall not cause the Participant to exceed the Maximum Percentage, at which time such Participant shall be delivered such Limited Shares to the extent as if there had been no such limitation. The provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this [Section 6B(g)] to correct this paragraph (or any portion hereof) which may be defective or inconsistent with the intended beneficial ownership limitation herein contained or to make changes or supplements necessary or desirable to properly give effect to such limitation.

Maximum Rate. In no contingency or event whatsoever shall the aggregate of all amounts deemed interest under this Agreement charged or collected pursuant to the terms of this Agreement exceed the highest rate permissible under any Applicable Law which a court of competent jurisdiction shall, in a final determination, deem applicable hereto. In the event that such a court determines that the Lenders have charged or received interest hereunder in excess of the highest applicable rate, the rate in effect hereunder shall automatically be reduced to the maximum rate permitted by Applicable Law and the Lenders shall at the Administrative Agent’s option # promptly refund to the Borrower any interest received by the Lenders in excess of the maximum lawful rate or # apply such excess to the principal balance of the Obligations. It is the intent hereof that the Borrower not pay or contract to pay, and that neither the Administrative Agent nor any Lender receive or contract to receive, directly or indirectly in any manner whatsoever, interest in excess of that which may be paid by the Borrower under Applicable Law.

The term “Maximum Limit” is defined as the largest amount which would result in no Payment being subject to any excise tax under the Golden Parachute Laws. The Executive and the ​ agree that, if the aggregate of all the Payments exceeds the Maximum Limit, the Executive would only be entitled to a portion of the Payments that he/she is eligible such that the total of the Payments that he/she receives would not exceed the Maximum Limit. The Executive has the discretion to determine which specific Payment or portion thereof he/she chooses to receive such that the aggregate of all Payments that he/she receives does not exceed the Maximum Limit.
