 Section 1. Grant of Option. The Company grants to
the Optionee the right and option (the “Option”) to purchase all or any part of an aggregate of such number of shares of Common Stock as is set forth in the Grant Notice (subject to adjustment as provided in Section 7 of the
Plan) on the terms and conditions set forth in this Agreement and in the Deltek Systems, Inc. 2005 Stock Option Plan (the “Plan”), a copy of which is being delivered to the Optionee concurrently herewith and is made a part hereof as
if fully set forth herein. Except as otherwise defined herein, capitalized terms used in this Agreement shall have the same definitions as set forth in the Plan. The Option is not intended to qualify as an Incentive Stock Option within the meaning
of Section 422 of the Code. 
 Section 2. Purchase Price. The price (the “Option Price”) at which the Optionee
shall be entitled to purchase shares of Common Stock upon the exercise of this Option shall be the price per share set forth in the Grant Notice (subject to adjustment as provided in Section 7 of the Plan). 
 Section 3. Duration of Option. The Option shall be exercisable to the extent and in the manner provided herein for a period of 10 years
after the date of grant; provided, however, that the Option may be earlier terminated as provided in Section 4, 6, 7, 8 or 9 below. 
 Section 4. Exercisability of Option. 
 4.1. Amount of Exercise. Subject to the
provisions of this Agreement and the Plan, the Option shall be exercisable in accordance with the following schedule: 
 (a) Prior to the
first anniversary of [Insert either (i) For new hires, the first day of employment or (ii) in all other situations, the grant date set forth in the Grant Notice] (the “Vesting Commencement Date,” the Option may not be
exercised; 
 (b) on or after the first anniversary of such Vesting Commencement Date but before the second anniversary of such Vesting
Commencement Date, the Option may be exercised to acquire up to 25% of the aggregate number of shares of Common Stock that may be purchased pursuant to the Option as set forth in Section 1, less any shares previously acquired pursuant to the
Option; 
 (c) on or after the second anniversary of such Vesting Commencement Date but before the third anniversary of such Vesting
Commencement Date, the Option may be exercised to acquire up to 50% of the aggregate number of shares of Common Stock that may be purchased pursuant to the Option as set forth in Section 1 hereof, less any shares previously acquired pursuant to
the Option; 







 (d) on or after the third anniversary of such Vesting Commencement Date but before the fourth anniversary
of such Vesting Commencement Date, the Option may be exercised to acquire up to 75% of the aggregate number of shares of Common Stock that may be purchased pursuant to the Option as set forth in Section 1 hereof, less any shares previously
acquired pursuant to the Option; and 
 (e) on or after the fourth anniversary of such Vesting Commencement Date, the Option may be exercised
to acquire up to 100% of the aggregate number of shares of Common Stock that may be purchased pursuant to the Option as set forth in Section 1 hereof, less any shares previously acquired pursuant to the Option. 
 4.2. Sales or Other Events. The Company shall give the Optionee at least five business days’ notice (or, if not practicable,
such shorter notice as may be practicable) (the “Sale Notice”) prior to the anticipated date of the consummation of a sale by the NMP Entities of any of their shares of Common Stock to a Third Party (an “NMP Sale”).
The Optionee shall be permitted to exercise the Option to the extent provided in this Section 4.2 in order to participate in the NMP Sale; provided, that, in the event of an NMP Sale in which the Optionee would be required to participate
pursuant to Section 3.5 of the Optionee Shareholders’ Agreement were the Optionee then a party to such agreement, the Company may require the Optionee to exercise the Option to the extent necessary to enable the Optionee to participate
therein or forfeit the Option (or portion thereof, as applicable). Notwithstanding anything in Section 4.1 to the contrary, in connection with an NMP Sale, the Option may be exercised to the extent of the excess, if any, of (a) the number
of shares with respect to which the Optionee would be entitled to, or is being required to, participate in an NMP Sale, and will so participate, over (b) the number of shares previously issued to the Optionee upon exercise of the Option and not
previously disposed of. Unless the Company elects to allow an earlier exercise of the Option, the exercise of an Option in connection with an NMP Sale shall be made in accordance with Section 5 and shall be made concurrently with the
consummation of the NMP Sale, and, in the event the NMP Sale is not consummated, any notice of exercise submitted in connection with the NMP Sale shall be of no force or effect and the Option shall be exercisable thereafter to the extent it would
have been exercisable if no Sale Notice or notice of exercise had been given. In lieu of permitting the Optionee to participate in a Public Offering of all or a portion of the shares of Common Stock owned by the NMP Entities (a “Secondary
Public Offering”), the Company, at its option, may instead cause the Option and the underlying shares to be registered under applicable securities laws, or make other arrangements consistent with such laws, so as to permit the Optionee to
sell for a period of time after the Secondary Public Offering the same number of shares that the Optionee would have been able to sell in the Secondary Public Offering but for this sentence. 
 4.3. Termination of Option. Subject to the provisions of Section 9 hereof, the Option shall terminate simultaneously with the
consummation of a Total Sale to the extent that the Option has not theretofore been exercised.

 4.4. Exercises Under Multiple Option Agreements. Notwithstanding anything herein to the contrary,
if, in connection with an NMP Sale, the Optionee shall be entitled to acquire shares of Common Stock pursuant to Section 4.2 hereof and pursuant to the analogous provisions of one or more other stock option agreements between the Optionee and
the Company (any such agreement, including this Agreement, an “Option Agreement”), then the Company shall have the right, at its option, to designate the Option Agreement or Option Agreements pursuant to which the Optionee may
exercise options for purposes of the Optionee’s participation in an NMP Sale, provided that in no event shall any such determination reduce the aggregate number of shares that the Optionee would otherwise be entitled to sell in
connection with such NMP Sale. 
 Section 5. Manner of Exercise and Payment. 
 5.1. Notice of Exercise. Subject to the terms and conditions of this Agreement and the Plan, the Option may be exercised by delivery of
written notice (the “Exercise Notice”) to the Company, provided, however, that until the Company has filed a Registration Statement on Form S-1, the Optionee shall give 90 days’ advance notice to the Company of the

of Common Stock in respect of which the Option is being exercised and shall be signed by the Optionee or, where applicable, by the Optionee’s Legal Representative. 
 5.2. Deliveries. The notice of exercise described in Section 5.1 shall be accompanied by (a) payment of the full purchase price for the shares in respect of which the Option is being exercised,

immediately available funds to an account designated by the Company, or other form of payment that is acceptable to the Company and (b) a fully executed Optionee Shareholders’ Agreement (a copy of which, in the form to be executed by the
Optionee (which may differ from optionee to optionee and from time to time), will be supplied to the Optionee upon request) and the undated stock power referred to in Section 6.14(a)(ii) of the Optionee Shareholders’ Agreement.

Option is being exercised and a fully executed Optionee Shareholders’ Agreement and stock power, and subject to Section 9 of the Plan, the Company shall take such action as may be necessary under applicable law to effect the issuance to
the Optionee of the number of shares of Common Stock as to which such exercise was effected. No fractional shares of Common Stock (or cash in lieu thereof) shall be issued upon exercise of an Option, and the number of shares of Common Stock that may
be purchased upon exercise shall be rounded to the nearest whole number.
