| | Re: | Executive Secondment to Deltek, Inc.
| | --- | ------------------------------------

Dear Hugo,

As you know, on November 30,
2010, the United States Citizenship and Immigration Services approved the L-1A visa application relating to your secondment to the US. The purpose of this letter is to confirm the general terms of your secondment from Maconomy A/S in Copenhagen,
Denmark to Deltek, Inc. (Deltek) in Herndon, Virginia, beginning December 1, 2010 through December 31, 2012. This secondment letter describes the terms specifically relating to your secondment to Deltek, Inc.

During the secondment, your service agreement dated 26 April 2005 including any addenda (the Service Agreement) will be suspended, and
the terms and conditions set out in this letter (including any appendices) will constitute your employment terms during the secondment. Although your Service Agreement will be suspended during this period, you will still be eligible to receive, as
provided by the Service Agreement, your 2010 bonus under the Maconomy bonus plan as well as the loyalty bonus you would be entitled to relating to Delteks acquisition of Maconomy.

Upon completion of the term of the secondment, you will return to Maconomy A/S, at which time the Service Agreement will enter into force again. Deltek
warrants that Maconomy A/S will accept both the suspension of the Service Agreement under the terms and conditions set out in this letter and the later re-instating of the Service Agreement.

I. Secondment



| | A. | Position

person as the CEO of Deltek shall designate.



| | B. | Term

Subject to mutual agreement between you and Deltek, the secondment may be extended by up
to 11 months.

II. Compensation

Your total current compensation is DKK 3,306,177. The components of your current compensation are salary and cash bonus. Based on the average exchange rate for the 180 days through December 14, 2010
(which is 5.65672:1), your current compensation is:



|             |  |     |           |  |     |  |         | 
|------------ |  | --- | --------- |  | --- |  | ------- | 
|             |  | DKK |           |  | USD | 
|Salary       |  |     | 2,361,555 |  |     |  | 417,478 | 
|Bonus Target |  |     | 944,622   |  |     |  | 166,992 | 
|             |  |     |           |  |     |  |         | 
|Total        |  |     | 3,306,177 |  |     |  | 584,470 | 

Consistent with
Delteks executive compensation program, as an EVP with revenue responsibility for AE/PS, your 2011 compensation will be split approximately 60% to salary and 40% to bonus. Based on your current compensation, as stated above, this would have
changed your 2010 compensation as follows:



|             |  |     |           |  |     |  |         | 
|------------ |  | --- | --------- |  | --- |  | ------- | 
|             |  | DKK |           |  | USD | 
|Salary       |  |     | 2,036,419 |  |     |  | 360,000 | 
|Bonus Target |  |     | 1,269,758 |  |     |  | 224,470 | 
|             |  |     |           |  |     |  |         | 
|Total        |  |     | 3,306,177 |  |     |  | 584,470 |

Deltek or the expiration thereof, the Service Agreement will be re-instated.

If both the secondment and your employment under
the Service Agreement are terminated by Deltek without Cause (as defined in Annex A), you will be entitled to (i) 90 days notice under this secondment letter, and (ii) an additional 12 months notice pay, consistent with
the terms of your Service Agreement.

In addition, in the unlikely event of your death, Deltek agrees to pay to your family an
amount equivalent to six months of your then-current base salary.

VIII. Miscellaneous

As a condition of the foregoing benefits, you will execute and deliver Delteks standard Employee Confidential Information,
Intellectual Property, and Non-Competition Agreement, which is attached as Annex B. As we have discussed, the commencement date for your obligations with respect to non-solicitation and non-competition under the Employee Confidential
Information, Intellectual Property, and Non-Competition Agreement shall begin on the notice date relating to the termination of the Service Agreement.

Your secondment to Deltek Inc., including the terms and conditions set out in this letter together with Annex A, is made and entered in the Commonwealth of Virginia. During the term of the secondment, the
terms of this letter shall be governed by, and interpreted under, the laws of the Commonwealth of Virginia, regardless of any principles of conflicts of laws or choice of laws of any jurisdiction, and the parties submit to the exclusive jurisdiction
of the state or federal courts of the Commonwealth of Virginia for such purposes. However, upon a termination of the secondment by Deltek, the terms of this letter shall then be governed by, and interpreted under, the laws of the Kingdom of Denmark,
regardless of any principles of conflicts of laws or choice of laws of any jurisdiction, and the parties submit to the exclusive jurisdiction of the City Court of Copenhagen for such purposes.

Hugo, we are excited to have you joining our team in the United States and look forward to growing the Company together.

Sincerely,

/s/ Kevin T. Parker

Kevin T. Parker

President and Chief Executive
Officer

Annex B

CONFIDENTIAL INFORMATION, INTELLECTUAL PROPERTY,

AND NON-COMPETITION
AGREEMENT

This Confidential Information, Intellectual Property, and Non-Competition Agreement (this
Agreement) is made and entered, as of the date set forth below, by and between Deltek, Inc. (Deltek) and
 (Employee). As a condition of Employees employment with Deltek, and in consideration for such employment, Employee agrees to the following terms:

1. Delteks Confidential Information.

a. Employee understands that, in the normal course of employment with Deltek, Employee will have access to, and in some cases will prepare
and create for Deltek, trade secrets and other confidential and proprietary information relating to the business and operations of Deltek and Delteks clients, including but not limited to: client and customer lists; information with respect to
the name, address, contact person, requirements, or potential needs of customers or clients; other information relating to clients and prospective clients from whom Deltek has solicited business or plans to solicit business; business plans and
strategies; research and development; technology; company processes and methodology; proprietary computer software and associated programs; information related to Delteks relationships with its partners, vendors, and/or suppliers; accounting
information; company policies; products and product design; technical matters; pricing and pricing structures; costs of doing business; business affairs, methods, objectives, and strategies; marketing plans; personnel information; and financial
information relating to Deltek and/or its clients or customers (collectively Confidential Information).

b.
Employee acknowledges and agrees that Confidential Information is developed by and for Deltek at considerable expense; that this information is a valuable Deltek asset and part of its goodwill; and that this information is vital to Delteks
success and is the sole property of Deltek. Employee acknowledges and agrees that Deltek is engaged in a highly competitive enterprise, so that any unauthorized disclosure or unauthorized use of the Confidential Information protected under this
Agreement, whether during Employees employment with Deltek or after Employees employment ends, would cause immediate, substantial and irreparable injury to the business and goodwill of Deltek. Employee acknowledges and agrees that such
Confidential Information, regardless of whether it is reduced to writing, is the exclusive property of Deltek.

c. Employee
will not, either during Employees employment or at any time after the termination of Employees employment with Deltek for any reason, on Employees own behalf or as a partner, officer, director, employee, agent, administrator,
advisor or consultant of any other person or entity, use, reproduce, or disclose Delteks Confidential Information to any person or entity other than as authorized by Deltek in the course of performing work for Deltek. Employee also will not
aid others in obtaining or using any such Confidential Information for any reason not in the best interests of Deltek. Employee agrees that he/she shall use the utmost care to protect the secrecy and confidentiality of Delteks Confidential
Information and shall take steps to ensure that unauthorized persons do not have access to Confidential Information.

2. Intellectual Property

a. Attached hereto as Exhibit A is a list describing all inventions, whether patentable or not, original works of authorship, sales lists,
software, computer code, development, improvements, and trade secrets which were made by Employee prior to Employees employment with Deltek, which relate to Delteks proposed business and products, and which are not assigned to Deltek;
or, if no such list is attached, Employee represents that there are no such inventions.

b. Employee agrees that Employee will
promptly make full written disclosure to Deltek, will hold in trust for the sole right and benefit of Deltek, and hereby assigns to Deltek all right, title, and interest in and to any and all inventions, original works of authorship, developments,
improvements or trade secrets which Employee has solely or jointly conceived or developed or reduced to practice, or caused to be conceived or developed or reduced to practice, during the period of time Employee has been in the employ of Deltek or
which Employee may solely or jointly conceive or develop or reduce to practice, during the period of time Employee shall be in the employ of Deltek. Employee acknowledges that all original works of authorship which have been and will be made by
Employee (solely or jointly with others) within the scope of employees employment and which are protectable by copyright are works made for hire, as that term is defined in the United States Copyright Act (17 USCA
Section 101).

c. Employee agrees to keep and maintain adequate and current written records of all inventions and
original works of authorship made by Employee (solely or jointly with others) during the term of employment with Deltek. The records will be in the form of notes, sketches, drawings, and any other format that may be specified by Deltek. The records
will be available to and remain the sole property of Deltek at all times.

d. Employee agrees that Employees obligation
to assist Deltek to obtain United States or foreign letters patent and copyright registrations covering inventions and original works of authorship assigned hereunder to Deltek shall continue beyond the termination of employment, but Deltek shall
compensate Employee at a reasonable rate for time actually spent by Employee at Delteks request on such assistance. If Deltek is unable because of Employees mental or physical incapacity or for any other reason to secure Employees
signature to apply for or to pursue any application for any United States or foreign letters patent or copyright registrations covering inventions or original works of authorship assigned to Deltek as above, then Employee hereby irrevocably
designates and appoints Deltek and its duly authorized officers and agents as Employees agent and attorney in fact, to act for and in Employees behalf and stead, to execute and further the prosecution and issuance of letters patent or
copyright registrations thereon with the same legal force and effect as if executed by Employee. Employee hereby waives and quitclaims to Deltek any and all claims, of any nature whatsoever, which Employee now or may hereafter have for infringement
of any patents or copyright resulting from any such application for letters patent or copyright registration assigned hereunder to Deltek.

3. Non-Competition

a. During Employees employment with Deltek and for a period of one (1) year after termination thereof, regardless of reason,
Employee will not engage in Competition with Deltek. For purposes of this Agreement, Competition shall mean:

(i) providing licensing, maintenance and/or consulting services with respect to Delteks proprietary software;

(ii) becoming engaged as a partner, officer, director, employee, agent, contractor, or consultant of any other person or entity that
provides licensing, maintenance and/or consulting services with respect to Delteks proprietary software, unless Employee is engaged in a capacity that does not include any of the duties that Employee performed for Deltek in the final two years
of Employees employment with Deltek, and that will not, whether intentionally or inevitably, involve any use or reliance on the Deltek Confidential Information in Employees possession;

and/or

(iii)
becoming engaged as a partner, officer, director, employee, agent, contractor, or consultant of a Competitor unless Employee is engaged in a capacity that does not include any of the duties that Employee performed for Deltek in the final two years
of Employees employment with Deltek, and that will not, whether intentionally or inevitably, involve any use or reliance on the Deltek Confidential Information in Employees possession.

For purposes of this Agreement, a Competitor is an individual or entity that (1) offers to business customers,
for sale or license, Deltek proprietary software or project-oriented computer software that provides similar functionality to the proprietary software offered by Deltek; and/or (2) provides maintenance and/or consulting services directly
related to such software.

b. Notwithstanding the foregoing, should Employee wish to become employed or otherwise engaged by a
Deltek business partner, Employee may be granted written permission to accept such an engagement, depending on the facts and circumstances involved. Employee should direct any request for such permission to the office of the General Counsel of
Deltek.

c. Nothing in this Agreement shall be construed to prohibit Employee from owning not more than one percent
(1%) of the total outstanding stock of any publicly held company.

4. Non-Solicitation

a. During Employees employment with Deltek and for a period of one (1) year after termination thereof, regardless of reason,
Employee will not solicit, personally or by assisting others, on behalf of a Competitor (defined above), any customer of Deltek with whom Employee had Material Contact during his/her employment with Deltek. Employee will be deemed to have had
Material Contact with a customer if, during the final two years of Employees employment with



11



---

LOGO



Deltek, Employee (i) directly interacted with such customer; (ii) supervised an employee who interacted with such customer; and/or (iii) obtained or received non-public information
related specifically to Delteks business or prospective business with such customer. Notwithstanding the foregoing, this Agreement shall not prevent Employee from soliciting customers on behalf of a Competitor if the Competitor engages in
multiple lines of business, including lines of business that are not covered by the definition of Competitor set forth above, and Employees solicitation relates exclusively to such other line(s) of business.

b. During Employees employment with Deltek and for a period of one (1) year after termination thereof, regardless of reason,
Employee will not solicit, personally or by assisting others, on behalf of a Competitor (as defined above), any employee, business partner, or contractor of Deltek with whom Employee had Material Contact during his/her employment with Deltek.
Employee will be deemed to have had Material Contact with an employee, business partner, or contractor if, during the final two years of Employees employment with Deltek, Employee (i) directly interacted with such employee,
business partner, or contractor; (ii) supervised such employee or contractor; or (iii) obtained or received non-public information specifically related to such employees employment, or such business partners or
contractors engagement, with Deltek.

5. Reasonableness of Restrictions.

a. Employee recognizes and agrees that Deltek has a legitimate need to protect its Confidential Information and its customer goodwill by
restricting, in the manner set forth in this Agreement, competition from persons to whom Deltek has given access to its Confidential Information and/or access to its existing and prospective customers.

b. With respect to customer goodwill, Employee acknowledges and agrees that any customer relationships developed, nurtured, fostered, or
generated by Employee during Employees employment with Deltek represent goodwill belonging to Deltek and are entitled to the protection afforded by the limited restrictions set forth in this Agreement, even if some such relationships existed
prior to Employees employment with Deltek.

c. With respect to the scope of Delteks business, Employee recognizes
that Delteks business is global in scope and that limiting the geographic scope of certain restrictions placed upon Employee would not adequately protect Delteks legitimate interests.

6. Employees Ability to Earn a Living.

By Employees signature below, Employee represents that, prior to signing this Agreement, Employee has (a) had an opportunity to
seek legal counsel if Employee so desired; (b) had an opportunity to ask questions of Deltek regarding this Agreement and the purpose for it; and (c) considered how the restrictions contained herein will affect Employees ability to
earn a living after his or her employment with Deltek ends. Employee acknowledges and agrees that, after reviewing the terms of this Agreement, Employee has concluded that the restrictions placed upon him/her in this Agreement are reasonable, and
that Employee possesses skills that will allow Employee to earn a living after leaving Deltek without violating the obligations set forth in this Agreement.

7. Return of Property

Employee agrees that, upon termination of Employees employment with Deltek for any reason, Employee is required to immediately
return to Deltek all property of Deltek, including without limitation: (i) all electronic and hard copy files in Employees possession that relate to Employees employment with Deltek, including e-mails; (ii) all manuals and
other documents relating to Delteks proprietary software; (iii) all computers and other electronic devices, such as Blackberries, issued by Deltek to employee; (iv) all security badges and keys; and (v) all other company
property that Employee received or obtained in the course of employment with Deltek. Employee specifically understands and agrees that Employee is not permitted to copy or erase any data from his/her computer, or any computer server of Deltek, prior
to or upon leaving employment with Deltek, other than in the normal course of Employees employment. Should Employee wish to copy or erase any electronic files from a company computer or server that Employee believes are personal to Employee,
Employee must request and obtain written permission from Deltek prior to copying or erasing any such data.

8. No
Other Agreements

By Employees signature below, Employee represents and warrants that (i) he/she is not
bound by the terms of any agreement with any previous employer or other party to refrain from competing, directly or indirectly, with the business of such previous employer or other party; (ii) to the best of Employees knowledge,
Employees performance of all of the terms of this Agreement and as an employee of Deltek does not and will not breach any agreement to keep in confidence proprietary information, knowledge or data acquired by Employee in confidence prior to
Employees employment with Deltek; and (iii) Employee will not knowingly disclose to Deltek, use on Delteks behalf, or induce Deltek to use any confidential or proprietary information or material belonging to any previous employer or
other party.

9. Employment At Will

Subject to the terms of the Secondment Letter, dated December 14, 2010, Employee acknowledges and agrees that Employees
employment with Deltek is at will, meaning that either Employee or Deltek may terminate the employment relationship, with or without cause and with or without advance notice, at any time. No agreement for employment for any specific period of time
is valid unless made in writing and signed by Employee and the Chief Executive Officer or Senior Vice President, Human Resources of Deltek.

10. Injunctive Relief

Employee acknowledges and agrees that
any breach of the provisions contained in this Agreement will cause Deltek immediate, material and irreparable injury, harm and damage, for which there may be no adequate remedy at law. Accordingly, in the event of any actual or threatened breach by
Employee of any of the provisions of this Agreement, in addition to any other remedies it may have at law or in equity, Deltek shall be entitled to seek enforcement of this Agreement in a court of competent jurisdiction by means of a decree of
specific performance, an injunction without the posting of a bond or the requirement of any other guarantee, and any other form of equitable relief.

This Agreement constitutes the entire agreement between the parties with respect to the matters addressed herein and supersedes all prior
agreements and understandings, whether written or oral, relating to the subject matter of this Agreement. This Agreement may be amended or modified only by a written instrument executed by both the Chief Executive Officer of Deltek and Employee. No
person has any authority to make any representation or promise on behalf of Deltek not set forth herein, and this Agreement has not been executed in reliance upon any representation or promise except those herein.

12. Severability.

This Agreement shall be enforceable to the fullest extent allowed by law. In the event that a court holds any provision of this Agreement to be invalid or unenforceable, Employee agrees that, if allowed
by law, that provision shall be deemed severable from the remainder of this Agreement, and the remaining provisions contained in this Agreement shall be construed to preserve to the maximum permissible extent the intent and purposes of this
Agreement.

the Eastern District of Virginia, shall have jurisdiction to hear and determine any dispute or controversy arising under or concerning this Agreement.

14. No Waiver.

Employee acknowledges and agrees that the
failure by Deltek to enforce any term of this Agreement shall not constitute a waiver of any rights or deprive Deltek of the right to insist thereafter upon strict adherence to that or any other term of this Agreement, nor shall a waiver of any
breach of this Agreement constitute a waiver of any preceding or succeeding breach. A waiver or consent given by Deltek on any one occasion shall be effective only in that instance and shall not be construed as a bar or waiver of any right on any
other occasion. No waiver of a right under any provision of this Agreement shall be binding on Deltek unless made in writing and signed by Deltek.
