actions required or permitted under the law of Texas to permit the payment of dividends on the Series B Preferred Stock, including, without limitation, through the revaluation of the Corporation’s assets in accordance with the law of Texas.

or other distribution with respect to any Junior Stock or (b) redeem, purchase or otherwise acquire for consideration any Junior Stock through a sinking fund or otherwise, unless (i) all accrued and unpaid dividends with respect to the

otherwise while any shares of Series B Preferred Stock remain outstanding. 
 7. No dividend shall be declared or paid on any Parity Stock
unless full cumulative dividends have been paid on the Series B Preferred Stock for all prior Dividend Periods; provided, however, if accrued dividends on the Series B Preferred Stock for all prior Dividend Periods have not been paid
in full then any dividend declared on the Series B Preferred Stock for any Dividend Period and on any Parity Stock shall be declared ratably in proportion to accrued and unpaid dividends on the Series B Preferred Stock and such Parity Stock.

 8. Notwithstanding anything herein to the contrary, the Corporation may declare and pay dividends on Junior Stock which are payable solely
in additional shares of or by the increase in the liquidation value of Junior Stock, as applicable, or repurchase, redeem or otherwise acquire Junior Stock in exchange for Junior Stock. 
 9. Unless the Corporation has previously exercised its optional redemption right with respect to all of the shares of Series B Preferred Stock then
outstanding, if a Debt Satisfaction Offer Default has occurred or a Fundamental Change Offer Default has occurred, then the Corporation shall pay to each holder of Series B Preferred Stock additional dividends computed by increasing the Applicable
Dividend Rate-Series B for the period from the Specified Debt Satisfaction Date or the date of such Fundamental Change, as the case may be, until the date the related Debt Satisfaction Offer Default or Fundamental Change Offer Default, as the case
may be, shall be cured, by (a) five percent per annum above the then Applicable Dividend Rate-Series B from the Specified Debt Satisfaction Date or the date of such Fundamental Change, as the case may be, through and including the Dividend
Payment Date for the first Dividend Period (such first Dividend Period, the “Initial Escalation Period”) that commences after the Specified Debt Satisfaction Date or the date of such Fundamental Change and (b) by an
additional five percent per annum above the then Applicable Dividend Rate-Series B (up to a maximum dividend rate of 25% per annum) at the beginning of each Dividend Period after the Initial Escalation Period.

Stock on the date required pursuant to the procedures described herein, such failure shall be deemed a Debt Satisfaction Offer Default or a Fundamental Change Offer Default, as applicable, for purposes hereof. If the Corporation makes a Debt
Satisfaction Offer or a Fundamental Change Offer and purchases all validly tendered shares of Series B Preferred Stock on the date required pursuant to the procedures described herein, then the Corporation shall have no obligation to pay additional
dividends with respect to any shares of Series B Preferred Stock which are not so tendered and purchased. 
 11. All such additional
dividends shall be paid in cash; provided, however, that any such additional dividends that are payable as a result of the occurrence of a Fundamental Change Offer Default or a Debt Satisfaction Offer Default prior to the Cash Payment
Date shall be deemed paid by increasing the periodic adjustments to the Accumulated Amount-Series B as set forth in the definition thereof. All references herein, in any context, to any dividend or other amount payable on or with respect to the
shares of the Series B Preferred Stock shall be deemed to include any additional dividend payable as described above. 
 12. All cash
dividends with respect to the Series B Preferred Stock pursuant to this paragraph D are payable when, as and if declared by the Board of Directors out of funds legally available therefor.

winding-up or dissolution of the Corporation, each holder of Series B Preferred Stock shall be entitled to receive and to be paid out of the Corporation’s assets available for distribution to the Corporation’s shareholders, before any
payment or distribution is made to holders of Junior Stock, an amount equal to the Series B Liquidation Preference per share of the Series B Preferred Stock held by such holder, plus accrued and unpaid dividends on the shares to the date fixed for
liquidation, winding-up or dissolution. If, upon the Corporation’s voluntary or involuntary liquidation, winding-up or dissolution, the amounts payable with respect to the Series B Preferred Stock and all Parity Stock are not paid in full, the
holders of the Series B Preferred Stock and the Parity Stock shall share equally and ratably in any distribution of the Corporation’s assets available for distribution to the Corporation’s shareholders in proportion to the full liquidation
preference and accrued and unpaid dividends to which they are entitled. After payment of the full amount of the Series B Liquidation Preference and accrued and unpaid dividends to which they are entitled, the holders of the Series B Preferred Stock
shall have no right or claim to any of the Corporation’s remaining assets. For purposes of this paragraph E, neither the sale of all or substantially all of the Corporation’s assets or business (other than in connection with the
liquidation, winding-up or dissolution of the Corporation), nor the merger or consolidation of the Corporation into or with any other person, shall be deemed to be a voluntary or involuntary liquidation, winding-up or dissolution of the Corporation.

 THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO THE PROVISIONS OF A STATEMENT OF
RESOLUTIONS ESTABLISHING AND DESIGNATING THE SERIES B PREFERRED STOCK OF THE CORPORATION. THESE SECURITIES MAY NOT BE TRANSFERRED EXCEPT IN ACCORDANCE WITH SUCH STATEMENT OF RESOLUTIONS. 
 3. No holder of Series B Preferred Stock may transfer, and the Corporation shall not register the transfer of, any shares of Series B Preferred Stock,
whether by sale, assignment, gift, bequest, appointment or otherwise, except to a U.S. Holder. 
 4. A holder of Series B Preferred Stock
may, subject to the other provisions of this paragraph L and applicable law, pledge such holder’s shares of Series B Preferred Stock to a pledgee pursuant to a bona fide pledge of such shares as collateral security for Indebtedness due to the
pledgee, provided that such shares shall not be transferred to or registered in the name of the pledgee. In the event of foreclosure or other similar action by the pledgee, such pledged shares of Series B Preferred Stock may only be transferred to a
U.S. Holder. 
 5. Any purported transfer of shares of Series B Preferred Stock not permitted hereunder shall be void and of no effect and
the purported transferee shall have no rights as a stockholder of the Corporation and no other rights against or with respect to the Corporation. The Corporation may, as a condition to the transfer or the registration of transfer of any shares of

exercised its termination option, additional dividends will not accrue on the Series B Preferred Stock, and the holders shall not be entitled to designate directors because of a Trigger Event or appoint a representative to the Board of Directors if
an event of default occurs under the Existing Term Loan Facility. In order to exercise its termination option, the Corporation shall irrevocably deposit in trust with the Transfer Agent, for the sole benefit of holders of the Series B Preferred
Stock, cash for the payment of the full redemption price and accrued and unpaid dividends to the redemption date.
