Form of Payment

•Directors may elect to receive all or a portion of their cash retainers (but not meeting fees) in the form of fully vested shares of common stock (election may be made in increments of 25%).

•The cash/stock election must be made prior to the last day of the calendar year preceding the year to which the retainers relate

•If a director fails to make a valid cash/stock election, all of his or her retainers will be paid in cash.

•If a director elects to receive all or a portion of his or her cash retainers in the form of fully vested shares of common stock, such shares will be issued to the director on the first day of each calendar quarter, in advance (and in the case of a newly-elected or appointed director, on the first day of his or her service for the then-current quarter).

•The number of shares of common stock to be issued to a director will be determined by dividing (1) the cash retainers to be paid in the form of fully vested shares of common stock, by (2) the "Trailing 60 Trading Day Weighted Average Price" (as defined below) for the Determination Period (as defined below)

up to and including the last day of the preceding calendar quarter, rounded up to the nearest whole share.

•The shares issued pursuant to a cash/stock election shall be granted under and shall be subject to the terms and provisions of the Parsons Corporation Incentive Award Plan (the “2019 Plan”), and, if a deferral election is made with respect to such shares, shall be granted subject to the execution and delivery of award agreements in substantially the forms previously approved by the Board.

•For purposes of this summary, the "Trailing 60 Trading Day Weighted Average Price" will be calculated by (1) first multiplying (A) the closing price per share of Parsons common stock for each trading day in the Determination Period, by (B) the closing volume of shares of Parsons common stock traded on such day, then (2) adding together the results in clause (1) for all of the trading days in the Determination Period, then (3) adding together the share volume in clause (B) for all of the trading days in the Determination Period, then (4) dividing the amount determined under clause (2) by the amount determined under clause (3).  The "Determination Period" will be the 60 trading days preceding the date of determination (e.g., if the Trailing 60 Day Weighted Average Price is to be determined for purposes of a grant date of January 1, the Determination Period will be the 60 trading days up to and including the preceding December 31).

Director Fee Deferral Plan

Each non-employee director is entitled annually to defer part or all of the retainer fee(s) and meeting fees, whether to be paid in cash or stock pursuant to a cash/stock election, in accordance with the deferral alternatives set forth in the Parsons Corporation Board of Directors Fee Deferral Plan for Outside Directors (the “Fee Deferral Plan”).  Any shares deferred pursuant to such a deferral election will be issued in the form of a deferred fee award consisting of a number of restricted stock units under the 2019 Plan determined in accordance with the formula above and reflecting the director’s deferral election.

Long-Term Incentive Compensation

From and after July 15, 2019:

On July 15, 2019 and on the first day of each calendar quarter occurring prior to the first annual shareholders' meeting, commencing October 1, 2019, each non-employee director will be granted such number of restricted stock units as is equal to (1) $40,000 divided by (2) the Trailing 60 Trading Day Weighted Average Price for the Determination Period up to and including the last day of the preceding calendar quarter, rounded up to the nearest whole share, as compensation for services during the preceding quarter.

From and after the first annual shareholders' meeting following the Effective Date, on the date of each annual shareholders' meeting, each non-employee director will be granted such number of restricted stock units as is equal to (1)

the annual target dollar amount (plus, with respect to the first annual shareholders' meeting following the Effective Date, a prorated quarterly

target dollar amount for the portion of the calendar quarter in which such meeting occurs preceding the date of such meeting), divided by (2) the Trailing 60 Trading Day Weighted Average Price for the Determination Period up to and including the last day preceding the date of grant, rounded up to the nearest whole share.

All restricted stock units will vest on the first anniversary of the date of grant (e.g., if the date of grant is October 1, 2019, the award will vest on September 30, 2020).  The restricted stock units will also vest upon a Change in Control (as defined in the 2019 Plan), or a non-employee director's death or disability, where disability shall mean an illness or other incapacitation which the Board determines is not a Section 409A Disability, but precludes such non-employee director from fully discharging his or her responsibilities as a member of the Board.  "Section 409A Disability" means, with respect to any non-employee director, a disability as defined in Treasury Regulation Section 1.409A-3(i)(4)(i), as such term is defined in Section 409A of the Internal Revenue Code.

Restricted stock unit award agreements for awards granted for 2019 service will include automatic deferral provisions pursuant to the form previously approved by the Board.  Restricted stock unit award agreements for awards granted for service in 2020 and after will permit deferrals of the restricted stock unit awards on terms similar to those under the Fee Deferral Plan.

The awards described above shall be granted under and shall be subject to the terms and provisions of the 2019 Plan, and shall be granted subject to the execution and delivery of award agreements in substantially the forms approved by the Board.

in the form of restricted stock units
