Share Unit Award Agreement

Exhibit A

1. For purposes of this Agreement, unless the context requires otherwise, the following terms shall have the meanings indicated:

a. “ Closing Price(s) ” shall on any date mean (i) the closing sale price per share (or if no closing sale price is reported, the average of the bid and ask prices or, if more than one in either case, the average of the average bid and the average ask prices) on that date as reported in the composite transactions table for the principal U.S. national or regional securities exchange on which the common stock is listed for trading; (ii) if the common stock is not listed for trading on a U.S. national or regional securities exchange on the relevant date, then the Closing Price of the common stock will be the average of the bid and ask prices (or, if more than one in either case, the average of the average bid and the average ask prices) for the common stock in the over-the-counter market on the relevant date as reported by OTC Markets Group Inc. or similar organization; and (iii) if the common stock is not so quoted, the Closing Price of the common stock will be such other amount as the Company may ascertain reasonably to represent such Closing Price. The Closing Price shall be determined without reference to extended or after-hours trading.

b. “ Final Stock Price ” shall mean the average of the Closing Prices for the ten (10) Trading Days during the period ending on and including the last Trading Day of the Measurement Period.

c. “ Initial Stock Price ” shall mean the average of the Closing Prices for the ten (10) Trading Days during the period preceding the first Trading Day of the Measurement Period.

d. “ Measurement Period ” shall mean the period commencing on and including the Date of Grant and ending on the Vesting Date (or, if earlier, the closing date of a Change in Control).

e. “ Peer Group ” shall be comprised of the following companies:

f. “ Trading Day(s) ” means a day on which (i) trading in the common stock generally occurs on the principal U.S. national or regional securities exchange on which the common stock is then listed or, if the common stock is not then listed on a U.S. national or regional securities exchange, on the principal other market on which the common stock is then traded, and (ii) a Closing Price for the common stock is available on such securities exchange or market.

Exhibit A – Page 1

g. “ TSR ” shall mean a company’s total shareholder return, which will be calculated by subtracting 1.0000 from the quotient obtained by dividing (i) the product of (A) the Final Stock Price for such company and (B) the number of Ending Shares (as determined below), by (ii) the Initial Stock Price. The “Ending Shares” shall be determined by calculating the total number of shares which would have been held at the end of the Measurement Period assuming: (a) the number of shares held at the beginning of the Measurement Period is 1.0000 and (b) each dividend and other distribution declared during the Measurement Period with respect to such shares (and any other shares previously received upon reinvestment of dividends or other distributions), without deduction for any taxes with respect to such dividends or other distributions or any charges in connection with such reinvestment, is reinvested into additional shares on the ex-dividend date at a price per share equal to the Closing Price on the trading day immediately preceding the ex-dividend date for such dividend or other distribution. The TSR of a component company in the Peer Group and of the Company shall be adjusted to take into account stock splits, reverse stock splits, and special dividends that occur during the Measurement Period. The determination of the TSR shall be subject to the following additional adjustments:

(I) If during the Measurement Period two component companies of the Peer Group merge or otherwise combine into a single entity, the surviving entity shall remain a component company of the Peer Group and the non-surviving entity shall be removed from the Peer Group.

(II) If during the Measurement Period a component company of the Peer Group merges into or otherwise combines with an entity that is not a component company of the Peer Group, such component company shall be removed from the Peer Group.

(III) If during the Measurement Period a component company of the Peer Group ceases to be a public company by becoming a private company through the “going dark” process, the Final Stock Price for such component company shall be measured over the last ten (10) Trading Days of the component company before it ceases to trade.

(IV) If during the Measurement Period a component company of the Peer Group files a petition for reorganization under Chapter 11 of the U.S. Bankruptcy Code or liquidation under Chapter 7 of the U.S. Bankruptcy Code, such component company shall remain as part of the Peer Group and be designated with a TSR of negative 100%.

2. Subject to certain restrictions and conditions set forth in the Plan and the Agreement, if, on the Vesting Date, the Company’s Percentile Rank (as defined below) within the Peer Group equals 35%, then 50% of the Target Units shall become Vested Units, and for every increase in the Company’s Percentile Rank within the Peer Group over 35%, a proportionate percentage of Target Units shall become Vested Units (up to 200% of the Target Units) on the Vesting Date (calculated on the basis of straight-line interpolation applied on the change in performance between threshold (35%) and target (50%), and between target (50%) and maximum (75%) levels of Percentile Rank), in accordance with the following schedule:

Exhibit A – Page 2

3. The Company shall calculate the TSR for the Company and each component company of the Peer Group over the Measurement Period. The Company and each company within the Peer Group shall be ranked from highest to lowest based on the TSR for each company. The percentile rank of the TSR of the Company will then be determined relative to the TSR ranking of each component company in the Peer Group (the “ Company’s Percentile Rank ”). In determining the number of companies in each percentile ranking, fractional numbers shall be rounded to the nearest whole number. The Company’s Percentile Rank will then be utilized, as shown in the table above, to determine the percentage, if any, of the Awarded Units that will vest under the Award and become Vested Units. Any fractional units created by such vesting will be rounded to the nearest whole unit.

4. The determination by the Company with respect to the achievement of the Company’s Percentile Rank for vesting of the Awarded Units shall occur as soon as administratively practicable after the Vesting Date or if earlier, the closing date of a Change in Control (and in all events on or before the date that is sixty (60) days following the Vesting Date or, if earlier, the closing date of a Change in Control).

If any arbitrator appointed hereunder shall die, resign, refuse, or become unable to act before an arbitration decision is rendered, then the vacancy shall be filled by the method set forth in this Section 25(b) for the original appointment of such arbitrator.

c. Each party shall bear its own arbitration costs and expenses. The arbitration hearing shall be held in Dallas, Texas at a location designated by a majority of the arbitrators. The Commercial Arbitration Rules of the American Arbitration Association shall be incorporated by reference at such hearing and the substantive laws of the State of Texas (without regard to conflict of laws principles) shall apply.

d.

The arbitration provisions of this Agreement shall, with respect to any such claim, controversy, or dispute, survive the termination or expiration of this Agreement.

f. No party to an arbitration may disclose the existence or results of any arbitration hereunder without the prior express written consent of the other party to this Agreement nor shall any party to an arbitration disclose to any third party any confidential information disclosed by any other party to such arbitration in the course of an arbitration hereunder without the prior express written consent of such other party.

g. Notwithstanding anything in this Section 25 to the contrary, any party may seek from a court any provisional remedy that may be necessary to protect any rights or property of such party pending the establishment of the arbitral tribunal or its determination of the merits of the claim, controversy, or dispute or to enforce the rights of such party under this Section 25 .

Share Unit Award Agreement

Exhibit A

1. For purposes of this Agreement, unless the context requires otherwise, the following terms shall have the meanings indicated:

a. “ Closing Price(s) ” shall on any date mean (i) the closing sale price per share (or if no closing sale price is reported, the average of the bid and ask prices or, if more than one in either case, the average of the average bid and the average ask prices) on that date as reported in the composite transactions table for the principal U.S. national or regional securities exchange on which the common stock is listed for trading; (ii) if the common stock is not listed for trading on a U.S. national or regional securities exchange on the relevant date, then the Closing Price of the common stock will be the average of the bid and ask prices (or, if more than one in either case, the average of the average bid and the average ask prices) for the common stock in the over-the-counter market on the relevant date as reported by OTC Markets Group Inc. or similar organization; and (iii) if the common stock is not so quoted, the Closing Price of the common stock will be such other amount as the Company may ascertain reasonably to represent such Closing Price. The Closing Price shall be determined without reference to extended or after-hours trading.

b. “ Final Stock Price ” shall mean the average of the Closing Prices for the ten (10) Trading Days during the period ending on and including the last Trading Day of the Measurement Period.

c. “ Initial Stock Price ” shall mean the average of the Closing Prices for the ten (10) Trading Days during the period preceding the first Trading Day of the Measurement Period.

d. “ Measurement Period ” shall mean the period commencing on and including the Date of Grant and ending on the Vesting Date (or, if earlier, the closing date of a Change in Control or the date of a Qualifying Termination).

e. “ Peer Group ” shall be comprised of the following companies:

f. “ Trading Day(s) ” means a day on which (i) trading in the common stock generally occurs on the principal U.S. national or regional securities exchange on which the common stock is then listed or, if the common stock is not then listed on a U.S. national or regional securities exchange, on the principal other market on which the common stock is then traded, and (ii) a Closing Price for the common stock is available on such securities exchange or market.

Exhibit A – Page 1

g. “ TSR ” shall mean a company’s total shareholder return, which will be calculated by subtracting 1.0000 from the quotient obtained by dividing (i) the product of (A) the Final Stock Price for such company and (B) the number of Ending Shares (as determined below), by (ii) the Initial Stock Price. The “Ending Shares” shall be determined by calculating the total number of shares which would have been held at the end of the Measurement Period assuming: (a) the number of shares held at the beginning of the Measurement Period is 1.0000 and (b) each dividend and other distribution declared during the Measurement Period with respect to such shares (and any other shares previously received upon reinvestment of dividends or other distributions), without deduction for any taxes with respect to such dividends or other distributions or any charges in connection with such reinvestment, is reinvested into additional shares on the ex-dividend date at a price per share equal to the Closing Price on the trading day immediately preceding the ex-dividend date for such dividend or other distribution. The TSR of a component company in the Peer Group and of the Company shall be adjusted to take into account stock splits, reverse stock splits, and special dividends that occur during the Measurement Period. The determination of the TSR shall be subject to the following additional adjustments:

(I) If during the Measurement Period two component companies of the Peer Group merge or otherwise combine into a single entity, the surviving entity shall remain a component company of the Peer Group and the non-surviving entity shall be removed from the Peer Group.

(II) If during the Measurement Period a component company of the Peer Group merges into or otherwise combines with an entity that is not a component company of the Peer Group, such component company shall be removed from the Peer Group.

(III) If during the Measurement Period a component company of the Peer Group ceases to be a public company by becoming a private company through the “going dark” process, the Final Stock Price for such component company shall be measured over the last ten (10) Trading Days of the component company before it ceases to trade.

(IV) If during the Measurement Period a component company of the Peer Group files a petition for reorganization under Chapter 11 of the U.S. Bankruptcy Code or liquidation under Chapter 7 of the U.S. Bankruptcy Code, such component company shall remain as part of the Peer Group and be designated with a TSR of negative 100%.

2. Subject to certain restrictions and conditions set forth in the Plan and the Agreement, if, on the Vesting Date, the Company’s Percentile Rank (as defined below) within the Peer Group equals 35%, then 50% of the Target Units shall become Vested Units, and for every increase in the Company’s Percentile Rank within the Peer Group over 35%, a proportionate percentage of Target Units shall become Vested Units (up to 200% of the Target Units) on the Vesting Date (calculated on the basis of straight-line interpolation applied on the change in performance between threshold (35%) and target (50%), and between target (50%) and maximum (75%) levels of Percentile Rank), in accordance with the following schedule:

Exhibit A – Page 2

3. The Company shall calculate the TSR for the Company and each component company of the Peer Group over the Measurement Period. The Company and each company within the Peer Group shall be ranked from highest to lowest based on the TSR for each company. The percentile rank of the TSR of the Company will then be determined relative to the TSR ranking of each component company in the Peer Group (the “ Company’s Percentile Rank ”). In determining the number of companies in each percentile ranking, fractional numbers shall be rounded to the nearest whole number. The Company’s Percentile Rank will then be utilized, as shown in the table above, to determine the percentage, if any, of the Awarded Units that will vest under the Award and become Vested Units. Any fractional units created by such vesting will be rounded to the nearest whole unit.

4. The determination by the Company with respect to the achievement of the Company’s Percentile Rank for vesting of the Awarded Units shall occur as soon as administratively practicable after the Vesting Date or if earlier, the closing date of a Change in Control or the date of a Qualifying Termination (and in all events on or before the date that is sixty (60) days following the Vesting Date or, if earlier, the closing date of a Change in Control or the date of a Qualifying Termination).
