CDI CORP.

EMPLOYMENT AGREEMENT

This EMPLOYMENT AGREEMENT (the “Agreement”) is entered into as of the 1st day of January, 2008 between CDI Corp., a Pennsylvania corporation (the “Company”), and Roger H. Ballou (“Executive”).

BACKGROUND

Executive has been employed by the Company since October 1, 2001, and has most recently been employed pursuant to the terms of an Employment Agreement between Executive and the Company dated as of August 11, 2005 (the “2005 Agreement”).

The Company desires to continue the Executive’s employment without interruption, and the Executive is willing to be so employed by the Company, upon the terms and subject to the conditions hereinafter set forth, with the understanding that to the extent that the Company and the Executive have obligations to each other under the 2005 Agreement that by the terms of that agreement survive the expiration of that agreement, those obligations shall remain in effect except to the extent specifically modified by this Agreement.

NOW, THEREFORE, in consideration of the mutual covenants set forth herein, and intending to be legally bound hereby, the parties agree as follows:

TERMS

SECTION 1. Employment.

The Company hereby employs Executive, and Executive hereby accepts such employment and agrees to serve as the Company’s President and Chief Executive Officer, and to render services to the Company and its subsidiaries, divisions and affiliates, during the Employment Period set forth in Section 3, subject to the terms and conditions hereinafter set forth.

SECTION 2. Management & Board Duties.

As President and Chief Executive Officer of the Company during the Employment Period, Executive shall carry out such duties as are customarily associated with the position of president and chief executive officer, which duties shall however in all cases be subject to policies set by, and at the direction and control of, the Company’s Board of Directors (the “Board of Directors”). The Company shall use its best efforts to have Executive nominated and elected to the Board of Directors during the Employment Period. During the Employment Period, Executive shall be afforded the full protection of the indemnifications generally available to officers and directors under the Company’s by-laws.

If Executive’s employment terminates by reason of the expiration of the Employment Period on March 31, 2011, and provided Executive does not become employed by another company for one year following that date, Executive will be considered to have retired on March 31, 2011. Benefits under the Company’s benefit plans will be paid as retirement benefits following March 31, 2012 if Executive does not become employed by another company during that one year period and as resignation benefits payable following Executive’s becoming employed by another company during that one year period if he does become so employed. This Agreement survives any termination of the Employment Period.

SECTION 4. Extent of Services.

During the Employment Period, Executive shall devote his full time and attention and give his best efforts, skills and abilities exclusively to the management and operations of the Company and its business and the business of its subsidiaries, divisions and affiliates. Executive shall perform his services hereunder at the Company’s offices in Philadelphia, Pennsylvania and at such other places as are required for the effective management of the Company and its business and the business of its subsidiaries, divisions and affiliates. During the Employment Period, Executive shall, if elected or appointed, serve as a director of the Company and as an executive officer and/or director of any subsidiary, division or affiliate of the Company and shall hold, without any compensation other than that provided for in this Agreement, the offices in, and directorships of, the Company and any such subsidiary, division or affiliate to which Executive may, at any time or from time to time, be elected or appointed.

It is understood and agreed that, as of the date of this Agreement, Executive is a member of the Board of Directors of two companies unrelated to the Company, and that Executive shall be free to devote up to 10 days per year to participation in the meetings and other activities of that Board. It is also agreed that Executive will not seek or accept any other board positions during the Employment Period.

(c) Bonus Awards. Executive shall be eligible to receive bonus compensation during the Employment Period. The bonus award during Executive’s employment with the Company shall be determined as follows:

(i) Within a mutually agreeable time period before the beginning of each calendar year, Executive shall submit to the Board of Directors for its approval the Company’s operational plan, including a fiscal budget, for the next calendar year. The Compensation Committee, all of the voting members of which shall be outside directors as defined in regulations issued under §162(m) of the Internal Revenue Code of 1986, as amended (the “Code”), and the Executive shall establish mutually agreed goals

- 4 -

each year based on the approved operational plan provided that (A) the Executive’s agreement to the goals proposed by the Compensation Committee shall not be unreasonably withheld and (B) at the time such goals are established, it is substantially uncertain whether they will be achieved.

(ii) The goals established by the Compensation Committee shall include a Target Goal, a Maximum Performance Goal, and such other Goals as the Committee shall determine to be appropriate and will be reasonably consistent with the goals applicable to other senior executives of the Company. The extent to which the goals have been achieved for any year or portion thereof shall be determined by the Compensation Committee.

(iii) The bonus to be paid Executive upon attaining the Target Goal for any calendar year shall be 80% of the Executive’s Base Salary for that year and the Bonus to be paid to the Executive upon attaining the Maximum Performance Goal for any such year shall be 120% of Executive’s Base Salary for that year. An appropriately prorated portion, as determined by the Compensation Committee of the Bonus payable upon attainment of the Target Goal will be paid for any year in which the Executive’s performance does not attain the Target Goal, but attains at least the minimum level required for payment of a bonus under the Company’s Bonus Plan for key employees as in effect for the year in question. If the Executive’s performance for such year exceeds the Target Goal, but not the Maximum Performance Goal, the bonus payable to the Executive shall be appropriately prorated. In determining whether the Target Goal or the Maximum Performance Goal has been met in any year, the Committee shall give appropriate weight, in accordance with generally accepted accounting principles consistently applied, to the effect on those Targets, and the Executive’s ability to attain them, of strategic decisions, such as acquisitions, divestitures or other extraordinary transactions of similar magnitude.

(iv) Any of the Company’s financial results that are used to calculate bonuses under this Section 5(c) shall be taken only from the Company’s audited financial statements for the applicable year.

(v) All cash bonuses payable under this Section 5(c) shall be paid to Executive within two weeks after the delivery of audited financial statements to the Company for the prior calendar year. Notwithstanding the foregoing, in the case of 2011, provided Executive’s employment ends because of the expiration of this Agreement, a bonus based on the reviewed financial statements for the first quarter of 2011 will be paid to Executive within forty-five (45) days of the date of filing of the Form 10-Q for such quarter with the SEC. No bonuses will be paid to Executive, if Executive’s employment with the Company has terminated

- 5 -

before the bonus has been paid, regardless of whether he would have been entitled to a bonus based on the Company’s financial results for the prior year, unless (A) the Company terminates Executive without Cause or the Executive terminates for Good Reason, both as defined in Section 7 or (B) the Executive’s termination is the result of Executive’s retirement as defined in Section 3. In such case, the Executive shall be entitled to a pro-rated bonus for the year of termination based on the achievement of goals and the period of Executive’s actual performance.

(d) Employee Benefits. During the Employment Period, Executive shall be entitled to participate in all employee benefit plans and programs approved by the Board of Directors as the Company shall provide generally to other senior executive officers of the Company from time to time, other than any bonus plans.

(e) Withholding. All payments to Executive or his estate made pursuant to this Agreement shall be subject to such withholding as may be required by any applicable laws. With respect to any payment of Deferred Stock under Section 5(b) of this Agreement, the number of shares of common stock of the Company to be delivered to Executive upon vesting of the Deferred Stock (including shares relating to dividends) shall be reduced by the number of shares having a Fair Market Value equal to all taxes (including, without limitation, federal, state, local or foreign income or payroll taxes) required by law to be withheld in connection with the vesting of the Deferred Stock. The portion of any shares of common stock of the Company withheld pursuant to the applicable tax laws shall be determined by using the Fair Market Value of CDI Stock on the last trading day immediately prior to vesting.

SECTION 6. Expense Reimbursements.

During the Employment Period, the Company shall reimburse Executive for all reasonable and itemized out-of-pocket expenses incurred by Executive in the ordinary course of the Company’s business, provided such expenses are properly reported to the Company in accordance with its accounting procedures. Executive shall be reimbursed as soon as practicable, but no later than the end of the year following the year during which the applicable expense was incurred.

SECTION 7. Termination.

(a) The Employment Period may be terminated by either the Board on behalf of the Company or the Executive as provided in this Section 7(a). In addition to the scheduled expiration of the Employment Period set forth in Section 3, the Employment Period shall terminate upon the earliest to occur of the following:

(i) the Executive’s death or Disability;

- 6 -

(ii) the close of business on the day which is 30 days after delivery by the Company to Executive of written notice of the Company’s election to terminate Executive’s employment hereunder, for any reason whatsoever; or

(iii) the close of business on the day which is 30 days after the date on which the Executive shall have delivered to the Company written notice of Executive’s election to terminate Executive’s employment hereunder.

If either subsection (ii) or (iii) above applies, the Company may at its option, require that the Executive’s employment be terminated at any point within the 30 day notice period selected by the Company, provided that, if subsection (ii) applies, for purposes of all compensation and benefits hereunder, the Executive’s employment will be deemed to have terminated at the end of the notice period provided under subsection (ii).

(b) For purposes of this Agreement, “Disability” shall have the same meaning as “Total Disability” under the CDI Corporation Long Term Disability Benefits Program, or such other comparable program as may then be in effect that provides long term disability coverage to the Company’s management employees.

(c) For purposes of this Agreement, “Cause” means any one or more of the following bases for termination of Executive’s employment with the Company:

(i) Executive’s conviction of, or entry of a plea of either guilty or no contest to a charge of, commission of a felony or other crime involving moral turpitude;

(ii) Executive’s failure or refusal to satisfactorily perform such services as may be reasonably delegated or assigned to Executive, consistent with his position, by the Board of Directors; provided, however, that a termination under this Section 7(c)(ii) shall not be for Cause unless the Company provides written notice to Executive of its intention to terminate Executive for Cause under this Section 7(c)(ii), and Executive fails, to the reasonable satisfaction of the Company, to cure the defects stated in such written notice within ten days after the notice was given to Executive;

(iii) Executive’s willful misconduct or gross negligence in connection with the performance of his duties under this Agreement that materially adversely affects Executive’s ability to perform his duties for the Company or materially adversely affects the Company;

- 7 -

(iv) Executive’s material breach of any of the terms or conditions of this Agreement;

(d) Following any termination of Executive’s employment hereunder, all obligations of the Company under this Agreement shall terminate except (i) any obligations with respect to the payment of accrued and unpaid salary or expense reimbursements under Sections 5 or 6 hereof through the date of Executive’s termination of employment hereunder or (ii) any severance specifically provided under Section 7(e) or 7(g) as applicable. The termination of the Company’s obligations under this Agreement shall not, however, affect any obligations to Executive under any Company benefit plans or other agreements that, by their terms, survive, or provide for benefits following, Executive’s termination of employment.

(e) In the event of any termination of Executive’s employment by the Company without Cause, by Executive for Good Reason, or by reason of the Executive’s retirement upon the termination of the Employment Period, as defined in Section 3, the Company shall, provided that the Executive continues to make any required payments as in effect immediately before Executive’s termination of employment, continue to pay for medical benefit plans and programs for Executive comparable to those in which Executive participated and for which the Company paid immediately prior to Executive’s termination, for the period commencing as of the Executive’s termination and ending on the last day of the month during which the Executive attains age 65 or the date the Executive accepts employment with another company, if earlier. In addition to the foregoing, in the event the Executive’s employment is terminated by the Company without Cause or by the Executive for Good Reason, the Company shall continue to pay Executive his Base Salary in the same intervals and amounts that were in effect immediately prior to termination, until the expiration of the Severance Period, as defined below. The “Severance Period” shall be the lesser of the remaining Employment Period or 12 months. Notwithstanding the above, no amounts shall be paid or become payable to Executive during the Severance Period until Executive has executed a valid release and waiver of all claims and potential claims against the Company and other related parties in a form that is reasonably satisfactory to the Company, and any required waiting period under such release and waiver has expired and Executive has not revoked the release during such waiting period. For the avoidance of doubt, a termination of Executive’s employment and the termination of the Employment Period during the first quarter of 2011 shall not be considered a termination by the Company without Cause nor by the Executive for Good Reason.

(i) “Good Reason” exists if the Executive voluntarily terminates employment with the Company, including following a Change in Control, as hereinafter defined, because (A) Executive is assigned duties that are demeaning or otherwise

- 8 -

materially inconsistent with the position and duties described in Section 2 hereof, (B) Executive’s place of employment with the Company is moved outside the Philadelphia metropolitan area or, following a Change in Control (C) Executive’s title is changed or (D) Executive’s principal place of employment is relocated by more than 50 miles. Before the Executive terminates for Good Reason, he must notify the Company in writing, within 30 days of the event or occurrence giving rise to “Good Reason,” of his intention to terminate and the Company shall have 15 days after receiving such written notice to remedy the situation, if possible.

(ii) “Change in Control” shall be deemed to have occurred if any “person” (as such term is used in Sections 13(d) and 14(d) of the Act), other than (A) the Company, (B) any “person” who on the date hereof is a director or officer of the Company, (C) any “person” who on the date hereof is the beneficial owner of 5% or more of the voting power of the Company’s outstanding securities or an affiliate of any such person or (D) a trust established under an employee benefit plan for employees of the Company of its subsidiaries, is or becomes the “beneficial owner,” (as defined in Rule 13d-3 under the Act), directly or indirectly, of securities of the Company representing more than 50% of the combined voting power of the Company’s then outstanding securities.

(iii) Any termination by the Company or by Executive of Executive’s employment hereunder shall be communicated by written notice.

(f) Except as provided in (g) below, any severance compensation granted in this Section 7 shall be the sole and exclusive compensation or benefit due to Executive upon termination of Executive’s employment.

(g) If within one year following a Change in Control Executive’s employment is terminated by the Company for any reason other than Cause, or if Executive’s Employment is terminated by the Executive for Good Reason following a Change in Control, then, in addition to any other benefits, including pursuant to option agreements and employee benefit plans, to which Executive may be entitled following such a Change in Control, the Executive shall be entitled to, in lieu of payments under Section 7(e), the maximum amount of additional cash compensation that can be paid to the Executive without the imposition on such payments of any excise tax under section 4999 of the Code or any loss of deduction by the Company under section 280G of the Code taking into account in such calculation the accelerated vesting of any outstanding equity awards. If it shall be finally determined that payments in excess of those limits have been made to the Executive, such payments shall be considered to have been a loan to the Executive by the Company and shall be repaid, with interest at the short term annual rate established under section 1274 of the code, upon demand by the Company.

- 9 -

(h) Notwithstanding any provision to the contrary in this Agreement, if (i) Executive is a “specified employee” within the meaning of Code Section 409A for the period in which the payment or benefits under this Agreement would otherwise commence and (ii) any payment or benefit under this Agreement would otherwise subject Executive to any tax, interest or penalty imposed under Code Section 409A of the Department of Treasury Regulations or other guidance promulgated thereunder, if the payment or benefit would commence within six months of a termination of Executive’s employment with the Company, then such payment or benefit shall not commence until the earlier of (A) the first day which is at least six (6) months after Executive’s separation from service within the meaning of Code Section 409A or (B) the date of Executive’s death.

SECTION 8. Representations, Warranties and Acknowledgments of Executive.

(a) Executive represents and warrants that his experience and capabilities are such that the provisions of Section 9 will not prevent him from earning his livelihood, and acknowledges that it would cause the Company serious and irreparable injury and cost if Executive were to use his ability and knowledge in competition with the Company or to otherwise breach the obligations contained in Section 9.

BRACKETING OF TARGETS

It is recognized that economic conditions may dramatically change from what was presented in the Strategic Plan of the Company, that unusually large revenues may be secured, or other unforeseen situations can arise that would make it wise to allow for some alterations of targets, up or down. The following outlines the process and range of modification of LTI targets permitted under this Agreement:

1. Any lowering of budgets or targets must first be submitted by the CEO and CFO, in writing to the Finance Committee of the Board with appropriate justification. After review and discussion, the Finance Committee can approve or withhold approval. Any increase to targets must be initiated by the Chairman of the Board and approved or approval withheld by the Finance Committee.

2. If a proposed adjustment is approved by the Finance Committee, the Compensation Committee of the Board will review the matter. With respect to this Employment Agreement the Compensation Committee can modify LTI targets at a percentage equal to that approved by the Finance Committee. Any lowering of targets could include lowering of the minimum PTP, the target PTP or both; and the same for any increase, that is, increasing of minimum PTP, target PTP or both. LTI payouts will be made in accordance with the payout matrix above. Any alteration of targets shall apply to the then current year only, and will be reviewed again during the next budget process.

EXHIBIT D

CEO STOCK HOLDING POLICY AND AGREEMENT

It has been CDI policy that the CEO is required to hold a minimum of four times base pay in equity of the Company.

For purposes of this Agreement, it is agreed that Executive must hold $2,500,000.00 of CDI stock by December 31, 2008.

Executive will be in compliance with this Policy and Agreement if the number of shares of CDI common stock held by the Executive at December 31, 2008, multiplied by the greater of (a) the average CDI stock price over the previous two complete calendar years (using the closing price on the NYSE on the last trading day in each of the 8 quarters, including the last closing price of the year, in those 2 calendar years to calculate the average) or (b) $25.35, equals at least $2,500,000.

Following the termination of this Agreement, Executive agrees to hold $1 million of equity (based on the closing share price as of Tuesday, January 18, 2011) until August 31, 2012.
