An "Equivalent Dividend," when used with reference to a dividend or distribution declared or paid on any class or series of Common Stock, shall mean a dividend in the same form and per share amount that is paid on another class or series of Common Stock, except that each class or series of Common Stock shall be considered to be identical to each other class or series in the case of dividends or distributions payable in capital stock or in debt or securities exchangeable or exercisable for, or convertible into, capital stock. 2. Liquidation. Subject to the provisions of law and the rights, if any, of the holders of any outstanding class or series of Preferred Stock or any class or series of stock having a preference over or right to participate with the Common Stock, in the event of any voluntary or involuntary liquidation, dissolution or winding up of the Corporation, the assets available for distribution to the holders of Common Stock shall be distributed to each of the holders of shares of all classes and series of Common Stock ratably on the basis of the number of shares held by such holder, without any preference or priority of any class or series over any other class or series. 3.

Notwithstanding the preceding sentence, the Corporation shall be required to indemnify a person described in such sentence in connection with any action, suit or proceeding (or part thereof) commenced by such person only if the commencement of such action, suit or proceeding (or part thereof) by such person was authorized by the Board of Directors of the Corporation.

If any provisions of this Article Sixth, Section 1 shall be found to be invalid or limited in application by reason of any law or regulation, such finding shall not affect the validity of the remaining provisions hereof.

Neither Harvest nor Investcorp shall have any duty not to (i) engage in, acquire or possess an interest in any other business venture of any kind, nature or description, independently or with others, whether or not such ventures are competitive with or in the same or similar lines of business as that of the Corporation or (ii) engage in business or other dealing with persons or entities transacting business with the Corporation. To the fullest extent permitted by Section 122(17) of the DGCL, the Corporation hereby renounces any interest or expectancy of the Corporation to participate in any such venture or business of Harvest or Investcorp, and acknowledges that none of Harvest, Investcorp or any Related Person shall be liable to the Corporation or its stockholders for breach of fiduciary duty solely by reason of the participation of Harvest or Investcorp, as applicable, in any such venture. 3. In the event that Harvest or Investcorp acquires knowledge of a potential transaction or matter which may constitute a corporate opportunity for either Harvest or Investcorp, on the one hand, and the Corporation, on the other hand, neither Harvest nor Investcorp shall have any duty to offer or communicate information regarding such corporate opportunity to the Corporation. To the fullest extent permitted by Section 122(17) of the DGCL, the Corporation hereby renounces any interest or expectancy of the Corporation in any such corporate opportunity and acknowledges neither Harvest nor Investcorp shall be liable to the Corporation or its stockholders for breach of any fiduciary duty as a stockholder of the Corporation by reason of the fact that Harvest or Investcorp pursues or acquires such corporate opportunity for itself, directs such corporate opportunity to another person or does not communicate information regarding such corporate opportunity to the Corporation. 4. In the event that a Related Person serving as an officer or director of the Corporation acquires knowledge of a potential transaction or matter which may constitute a corporate opportunity for both the Corporation, on the one hand, and Harvest or Investcorp, on the other hand, such officer or director shall have no duty to offer or communicate information regarding such corporate opportunity to the Corporation except as provided below. To the fullest extent permitted by Section 122(17) of the DGCL, the Corporation hereby renounces any interest or expectancy of the Corporation in any such corporate opportunity and acknowledges that such officer or director shall not be liable to the Corporation or its stockholders for breach of any fiduciary duty by reason of the fact that Harvest or Investcorp pursues or acquires such corporate opportunity for itself, directs such corporate opportunity to another person or does not communicate or offer information regarding such corporate opportunity to the Corporation; provided, however, that any corporate opportunity that is expressly offered to a Related Person in writing solely in his or her capacity as an officer or director of the Corporation shall belong to the Corporation. 5. Any person or entity purchasing or otherwise acquiring any interest in any shares of capital stock of the Corporation shall he deemed to have notice of, and to have consented to, the provisions of this Article Eighth.
