The Committee has sole and absolute authority and discretion to decide the time and manner in which STI Awards, if any, shall be paid under the Plan, but in no event shall any such STI Awards be paid later than the March 15 following the calendar year to which such STI Awards relate. The Committee's determination as to the time and manner of payment is binding and conclusive on all Eligible Employees. Generally, however, the following provisions apply:

(a)Payment Form: Each STI Award under the Plan will be paid in cash in one lump sum, less withholding for all applicable federal, state or local taxes and other deductions, if any, in effect when such STI Award is paid.

(b)Adjustments: The Partnership may exercise its discretion to adjust (upward or downward, including to zero) any STI Award at any time before such STI Award has been paid for any reason or for no reason whatsoever.

(c)Termination, Death or Disability: STI Awards will be paid only to Eligible Employees who are employed by the Partnership or one of its Affiliates on the applicable payment date. An Eligible Employee shall forfeit all unpaid STI Awards granted to such Eligible Employee if his or her employment terminates for any reason other than the circumstances described in Section 8(c)(i) or (ii) before the applicable payment date. All amounts that would otherwise have been payable in respect of STI Awards that are forfeited shall be allocated and paid in such manner as the Committee determines, in its sole discretion, to one or more Eligible Employees or to one or more employees of the Partnership or any of its Affiliates pursuant to another bonus or short-term incentive plan or arrangement sponsored or maintained by the Partnership or one of its Affiliates from time to time, including, without limitation, the Boardwalk Operating GP, LLC Non-Exempt Employee Annual Short-Term Incentive Plan.

(i)If an Eligible Employee's employment terminates due to such Eligible Employee's death, Disability or Retirement on or before the last day of a calendar year, the Eligible Employee (or, if applicable, the Eligible Employee's estate) will be paid a pro-rata portion of each STI Award granted to such Eligible Employee for such calendar year based upon the number of days during such calendar year that such Eligible Employee was employed by the Partnership or one of its Affiliates. A prorated payment of an STI Award for a particular calendar year will be made at the same time and in the same form that payments of STI Awards for such calendar year are paid to all other Eligible Employees who remain actively employed by the Partnership or one of its Affiliates.

(ii)If an Eligible Employee's employment terminates due to such Eligible Employee's death, Disability or Retirement after the end of a calendar year but before the STI Award payment date with respect to such calendar year, then such Eligible Employee (or, if applicable, such Eligible Employee's estate) will receive the full amount of the STI Award to which he or she would otherwise be entitled. Payment shall be made at the same time and in the same form that payments of STI Awards for such calendar year are paid to all other Eligible Employees who remain actively employed by the Partnership or one of its Affiliates.

(iii)Notwithstanding any provision in the Plan to the contrary:

(A)An Eligible Employee's employment shall not be deemed to terminate because such Eligible Employee is absent from active employment due to short-term disability, authorized paid time off, temporary leaves of absence granted by the Partnership for professional advancement, education, health or government service or military leave for any period if the Eligible Employee returns to active employment within 90 days after military leave terminates, or during any period required to be treated as a leave of absence by any valid law or agreement; and

(B)The Committee, in its sole discretion, may waive all or part of the provisions of this Section 8 with respect to STI Awards whenever the Committee, in its sole discretion, deems such waiver to be appropriate. Any such waiver shall not be binding on the Committee, the Partnership or any of the Partnership's Affiliates with respect to any other Eligible Employee, whether or not similar circumstances exist.

(d)Section 409A of the Code: It is intended that the STI Awards under the Plan qualify as short-term deferrals exempt from the requirements of Section 409A of the Code. In the event that any STI Award does not qualify for treatment as an exempt short-term deferral, it is intended that such amount will be paid in a manner that satisfies the requirements of Section 409A of the Code. The Plan shall be interpreted and construed in accordance with such intent.

(e)No Trust: The establishment of the Plan shall not be deemed to create a trust. The Plan shall constitute an unfunded, unsecured liability of the Partnership to make payments in accordance with the provisions of the Plan, and no individual shall have any security or other interest in any assets of the Partnership or any of its Affiliates or in the equity interests of the Partnership or otherwise.

11.No Guaranteed Employment.

Neither the maintenance of the Plan nor any action taken hereunder shall confer on any Person the right to continued employment by the Partnership or any of its Affiliates for any definite period of time, or affect in any way the right of the Partnership or any of its Affiliates to terminate such employment at any time.
