CDI CORP. STOCK PURCHASE PLAN FOR MANAGEMENT EMPLOYEES AND NON-EMPLOYEE DIRECTORS Article 1. General Description The CDI Corp. Stock Purchase Plan for Management Employees and Non-Employee Directors (the "Plan") provides designated management employees and non-employee members of the Company's Board of Directors with the opportunity to purchase CDI Stock on a pre-tax basis. In addition, many Participants will be eligible to receive an additional contribution of CDI Stock from the Company. Under the Plan, management employees use a portion of their Annual Bonus Awards and non-employee directors use a portion of their Directors' Fees to purchase "units", each of which represents a share of CDI Stock. After a Vesting Period elapses, a number of shares of CDI Stock equal to the number of "units" which have vested will be delivered to the Participant. Article 2. Purpose and Effective Date 2.1.

Participation is either mandatory or voluntary. 4.1 Mandatory Participation. Certain senior executives designated by the Committee are required to participate in the Plan and will automatically have 25%, or such other percentage as the Committee may determine, of the pre-tax amount of their Annual Bonus Awards withheld and used to purchase SPP Units. 4.2 Voluntary Participation. Any Eligible Employee may participate on a voluntary basis by electing to have up to 25%, or such other maximum percentage as the Committee may determine, of the pre-tax amount of his or her Annual Bonus Award withheld and used to purchase SPP Units. For those Eligible Employees subject to mandatory participation, this amount is in addition to the automatic, required withholding described in 4.1. 4.3 Company Matching Contributions. Unless otherwise determined by the Committee, the Company will make a matching contribution to an Employee Participant's SPP Account of one SPP Unit for every three SPP Units purchased by the Employee Participant through voluntary, but not mandatory, participation. 4.4 Calculation of SPP Units and Crediting of SPP Accounts. The number of SPP Units which will be credited to an Employee Participant's SPP Account will be calculated by dividing the amount of the Employee Participant's Annual Bonus which is being used to purchase SPP Units by the Fair Market Value of a share of CDI Stock on the date the Employee Participant's SPP Account is credited. Employee Participants' SPP Accounts will be so credited as promptly as is practicable following the public release of the Company's audited financial results for the Fiscal Year for which the applicable Annual Bonus Award is being calculated. 4.5 Employee Participant Elections. On or before June 30th of each year, or such other date as the Committee may determine, an Employee Participant must notify the Company of (i) that percentage of the Employee Participant's Annual Bonus Award, if any, which the Employee Participant will earn for that year which the Employee Participant elects to use to purchase SPP Units, and (ii) the number of years which the Employee Participant elects to have in the Vesting Period for those SPP Units. If the Employee Participant fails to make such an election, the Employee Participant will be 4 deemed to have elected not to make any voluntary purchases of SPP Units for that year and to have elected a three year vesting period for any SPP Units purchased through mandatory participation for that year. Article 5. Director Participation An Eligible Director participates in the Plan by using a portion of his or her Director's Fees to purchase SPP Units. Participation is either mandatory or voluntary. 5.1 Mandatory Participation.

Eligible Directors may voluntarily elect to have up to 100% of the pre-tax amount of their Director's Fees withheld and used to purchase SPP Units. 5.3 Company Matching Contributions. Unless otherwise determined by the Committee, the Company will make a matching contribution to a Director Participant's SPP Account of one SPP Unit for every three SPP Units purchased by the Director Participant through voluntary, but not mandatory, participation. 5.4 Calculation of SPP Units and Crediting of SPP Accounts. The number of SPP Units that will be credited to a Director Participant's SPP Account will be calculated by dividing the amount of the Director's Fees that are being used to purchase SPP Units by the Fair Market Value of a share of CDI Stock on the date the Director Participant's SPP Account is credited. 5.5 Director Participant Elections. Prior to the first day of a Director Year, the Director Participant must notify the Company of (i) that percentage of such Director's Fees for that Director Year, if any, that the Director Participant elects to use to purchase SPP Units, and (ii) the number of years which the Director Participant elects to have in the Vesting Period for those SPP Units. If the Director Participant fails to make such an election, the Director Participant will be deemed to have elected not to make any voluntary purchases of SPP Units for that year and to have elected a three year vesting period for any SPP Units purchased through mandatory participation for that year. Article 6. Vesting 6.1 All SPP Units purchased or contributed to a Participant's SPP Account for a particular year will be subject to a Vesting Period of from three to ten years, as chosen by the Participant. A Vesting Period chosen for a particular year's SPP Units will be 5 applicable to all SPP Units acquired for that year - whether through mandatory or voluntary purchase or through matching Company contribution - and will run from the date the SPP Units are credited to the Participant's SPP Account. 6.2 When a Vesting Period elapses, a certificate for a number of shares of CDI Stock equal to the number of SPP Units which were subject to the elapsed Vesting Period will be delivered to the Participant, and the SPP Units will be cancelled. 6.3 SPP Units may not be sold, pledged or transferred during the Vesting Period. 6.4 If a Participant's employment or service with the Company terminates before the Vesting Period applicable to any SPP Units has elapsed, the following will apply: (i) if the termination occurs less than three years after the purchase of the SPP Units and is by the Company for Cause or as a result of the Participant's resignation (other than for retirement), the Participant will receive, in cash and not CDI Stock, the lesser of the amount paid for the SPP Units or the then current market price of the underlying shares of CDI Stock. (Participants will forfeit any SPP Units credited to his or her account as a result of matching Company contributions); or (ii) if the termination occurs more than three years after the purchase of the SPP Units for any reason whatsoever, or if the termination occurs at any time after the purchase of the SPP Units due to the retirement of the Participant or for reasons other than termination by the Company for Cause or the Participant's resignation, then the unvested SPP Units will immediately vest and a number of shares of CDI Stock equal to the number of such SPP Units will be delivered to the Participant or his or her Personal Representative (For this purpose, a Director's choice not to stand for re-election as a Director will be treated as a retirement).

No such amendment, suspension, or termination shall alter or impair any outstanding SPP Units without the consent of the Participant adversely affected thereby. 9.5 Nonuniform Determinations. The Committee's determinations under the Plan, including without limitation, the determination of Eligible Employees, need not be uniform and may be made by it selectively among Participants whether or not such Participants are similarly situated. 9.6 No Right to Employment or Continued Service. Neither the action of the Company in establishing the Plan, nor any action taken by it or by the Board or the Committee under the Plan, nor any provision of the Plan or any Agreement, shall be construed as giving to any person the right to be retained in the employ of the Company. 9.7 Funding; Unsecured Status. The Company will not be required to segregate or hold separately from its general assets any amounts credited to a Participant's SPP Account, and shall be under no obligation whatsoever to fund in advance any amounts under the Plan.
