Transactions by Mr. Bennett

Mr. Bennett received an award of 6,358 restricted shares of Common Stock on January 4, 2010 under the Patriot 2007 Long-Term Equity Incentive Plan (the "Plan"). The restricted stock awarded under the Plan will ratably vest in annual installments over a period of three years following the grant date; i.e., 33.33% of the award will be vested on the first anniversary of the grant date, 66.66% of the award will be vested on the second anniversary of the grant date and 100% of the award will be vested on the third anniversary of the grant date. The restricted stock will become fully vested if the Mr. Bennett terminates employment with the Issuer because of death or disability, or if a change in control occurs. In the event that Mr. Bennett's employment is terminated without cause or by Mr. Bennett for good reason, the restricted stock will vest with respect to the percentage of shares of Common Stock of the Issuer that would have otherwise vested on the next vesting date.

Mr. Bennett also received 12,716 non-qualified stock options on January 4, 2010 at an exercise price of $17.30 per share under the Plan.   The stock options will be 33.33% exercisable on January 4, 2011, 33.33% exercisable on January 4, 2012 and 33.34% exercisable on January 4, 2013 or earlier if Mr. Bennett terminates employment with the Issuer because of death or disability, or if a change in control occurs.  In the event that Mr. Bennett's employment is terminated without cause or by Mr. Bennett for good reason, the stock options will vest and become exercisable with respect to the percentage of shares of Common Stock of the Issuer that would have otherwise vested on the next vesting date.  Except as provided in the preceding sentence, any part of the stock options that are not exercisable will be terminated if Mr. Bennett terminates employment with The Issuer for any reason other than death or disability prior to the time such stock options have become vested and exercisable.  No stock options can be exercised more than ten years after the date of grant, but the ability to exercise the stock options may terminate sooner upon the occurrence of certain events.

Finally, Mr. Bennett received 6,538 performance-based restricted stock units (the "RSUs") under the Plan.  The RSU's granted are subject to satisfaction of certain performance-based parameters tied to total shareholder return ("TSR") relative to a peer group (or satisfaction of a specified TSR (the "Minimum TSR")), as described in the award agreement.  The RSUs will vest on December 31, 2012, or earlier if Mr. Bennett terminates employment with the Issuer because of death or disability, or if a change in control occurs.  The number of shares reported represent the minimum number of shares that may be awarded if the actual TSR exceeds the Minimum TSR.  All unvested RSUs will be forfeited if Mr. Bennett terminates employment with the Issuer for any reason other than death or disability, provided however, in the event that Mr. Bennett's employment is terminated without cause or by Mr. Bennett for good reason, a pro rata portion of the RSUs will vest.

In addition, Mr. Vining received an award of 23,121 restricted shares of Common Stock on January 4, 2010 under the Patriot 2007 Long-Term Equity Incentive Plan (the "Plan"). The restricted stock awarded under the Plan will ratably vest in annual installments over a period of three years following the grant date; i.e., 33.33% of the award will be vested on the first anniversary of the grant date, 66.66% of the award will be vested on the second anniversary of the grant date and 100% of the award will be vested on the third anniversary of the grant date. The restricted stock will become fully vested if the Mr. Vining terminates employment with the Issuer because of death or disability, or if a change in control occurs. In the event that Mr. Vining's employment is terminated without cause or by Mr. Vining for good reason, the restricted stock will vest with respect to the percentage of shares of Common Stock of the Issuer that would have otherwise vested on the next vesting date.

Mr. Vining also received 46,242 non-qualified stock options on January 4, 2010 at an exercise price of $15.45 per share under the Plan.  The stock options will be 33.33% exercisable on January 4, 2011, 33.33% exercisable on January 4, 2012 and 33.34% exercisable on January 4, 2013 or earlier if Mr. Vining terminates employment with the Issuer because of death or disability, or if a change in control occurs.  In the event that Mr. Vining's employment is terminated without cause or by Mr. Vining for good reason, the stock options will vest and become exercisable with respect to the percentage of shares of Common Stock of the Issuer that would have otherwise vested on the next vesting date.  Except as provided in the preceding sentence, any part of the stock options that are not exercisable will be terminated if Mr. Vining terminates employment with the Issuer for any reason other than death or disability prior to the time such stock options have become vested and exercisable.  No stock options can be exercised more than ten years
 
 

 
 
after the date of grant, but the ability to exercise the stock options may terminate sooner upon the occurrence of certain events.

Finally, Mr. Vining received 23,121 performance-based restricted stock units (the "RSUs") under the Plan.  The RSUs are subject to satisfaction of certain performance-based parameters tied to total shareholder return ("TSR") relative to a peer group (or satisfaction of a specified TSR (the "Minimum TSR")), as described in the award agreement.  The RSUs will vest on December 31, 2012, or earlier if Mr. Vining terminates employment with the Issuer because of death or disability, or if a change in control occurs.  The number of shares reported represent the minimum number of shares that may be awarded if the actual TSR exceeds the Minimum TSR.  All unvested RSUs will be forfeited if Mr. Vining terminates employment with the Issuer for any reason other than death or disability, provided however, in the event that Mr. Vining's employment is terminated without cause or by Mr. Vining for good reason, a pro rata portion of the RSUs will vest.
