direct a highly skilled and motivated management team, (iii) provide an
effective means for selected management personnel to acquire and maintain
ownership of CDI Stock, (iv) motivate selected management personnel to achieve
long-range performance goals and objectives, and (v) provide incentive

The Committee will be composed entirely of persons who are both an "Outside
Director" (as such term is defined or interpreted for purposes of Section 162(m)
of the Internal Revenue Code of 1986, as amended) and an "Independent Director"
(as such term is defined or interpreted for purposes of Rule 16b-3 under the
Securities Exchange Act of 1934, as amended). Except with respect to Retainer
Fee Options, the Committee may determine from time to time which eligible
persons shall be granted Options under the Plan, the number of shares of CDI
Stock to be subject to the Option in each case and the other substantive
provisions of each Option. However, any Options, other than Retainer Fee
Options, granted to a member of the Board must also be approved by a majority of
the Board not including the recipient.

        6.   Retainer Fee Options.

             (a) All or a portion of the Retainer Fee payable to Eligible
Directors may, at the election of the Director, be paid in the form of Options.
Prior to the beginning of each Retainer Fee Year, each Eligible Director may
elect to receive Options in lieu of all or a portion of the cash Retainer Fee
that such Director would otherwise be paid for his/her service as a Director
during such Retainer Fee Year. On the first business day of each Retainer Fee
Year each Director who has made such an election will be granted an Option for
that number of shares of CDI Stock which will result in the Option having the
value chosen by the Director, using a Black-Scholes valuation as of such date of
grant. Such number of shares will be subject to adjustment as provided in
Paragraph 14.

             (b) The Committee may determine from time to time the terms of the
Retainer Fee Options, provided such terms are consistent with the terms of the
Plan. Unless otherwise determined by the Committee, (i) Retainer Fee Options
shall vest (and therefore will be exercisable) upon the completion of the
Retainer Fee Year for which the Retainer Fee Options have been granted, (ii) if
an Eligible Director ceases to be a member of the Board for any reason, unvested
Retainer Fee Options shall expire and be unexercisable and the portion of the
Eligible Director's Retainer Fee earned as of the date of cessation that is
represented by such unvested Retainer Fee Options shall be paid in cash and
(iii) vested Retainer Fee Options will not terminate until the expiration of the
options' full terms notwithstanding an earlier termination of a Director's
service as a Director of the Company.

        7.   Eligibility.  The Committee may, from time to time, subject to the
provisions of the Plan and such terms and conditions as the Committee may
prescribe, award Options to any Eligible Employee or Eligible Consultant.  Only
Eligible Directors shall be eligible to receive Retainer Fee Options pursuant to
Paragraph 6.

        8.   Option Exercise Price.

             (a) The price at which CDI Stock may be purchased on exercise of an
Option shall be determined in each case by the Committee, but may not be less
than 100% of the Fair Market Value of the CDI Stock on the last trading date
immediately preceding the Date of Grant; provided, however, that the price at
which CDI Stock may
<PAGE>
                                                                              64

be purchased on exercise of a Retainer Fee Option shall be the Fair Market Value
of CDI Stock on the last trading day immediately preceding the Date of Grant.

             (b) Upon exercise of any Option granted pursuant to the Plan, the
Optionee shall pay the Option price in cash or, in whole or in part, through the
transfer to the Company of shares of CDI Stock that have been held by the
Optionee for at least six months. In the event such Option price is paid in
whole or in part with shares of CDI Stock, the portion of the Option price so
paid shall be equal to the Fair Market Value of CDI Stock on the last trading
day immediately preceding such date of exercise.

        9.   Issuance of Certificates; Payment of Cash.

             (a) Upon payment of the Option price and satisfaction of the tax
payment obligation set forth in Paragraph 9(b), a certificate for the number of
whole shares of CDI Stock to which the Optionee is entitled shall be delivered
to such Optionee by CDI Corp.

             (b) The Company shall not issue or transfer CDI Stock upon exercise
of an Option until the Option price is fully paid and the tax withholding
obligations with respect to the exercise of the Option have been satisfied. The
Optionee may satisfy any statutory amounts required to be withheld under
applicable federal, state and local income, payroll, social security and similar
tax laws in effect from time to time by remitting the required amount of cash to
the Company or by electing to have the Company withhold that number of shares of
CDI Stock being purchased through the exercise of the Option which have a Fair
Market Value equal to the amount of tax to be paid.

        10.  Term.  Unless otherwise determined by the Committee, Options
granted under the Plan shall not be exercisable after the Termination Date.

        11.  Vesting.  Unless otherwise determined by the Committee, Options
granted under the Plan will vest as follows:

             (a) Subject to the accelerated vesting provision of Paragraph
11(b), Options will vest at the rate of 20% per year on each of the first five
anniversaries of the Date of Grant;

             (b) If an Optionee's employment with the Company terminates as a
result of the Optionee's Retirement, death or Total and Permanent Disability,
the Option will vest as to all unvested shares as of the date of such event.

        12.  Exercise of Options. Unless otherwise determined by the Committee,
the vested portion of an Option may be exercised in whole or in part during its
term, but only as to whole shares, provided that an Option shall be exercisable
only by an Optionee during his lifetime, by his Personal Representative in the
event of the Optionee's death or Total and Permanent Disability, or by any
permitted transferee under Paragraph 13.

                                                                              65

        13. Transferability of Options. No Option may be transferred, in whole
or in part, unless the Option is transferred (i) by will or the applicable laws
of descent and distribution, or (ii) to the extent allowed under the terms of
the Agreement, to the spouse or descendant of an Optionee or to a trust for the
benefit of the spouse or descendant of an Optionee.

        14. Adjustment on Change in Capitalization. In case the number of
outstanding shares of CDI Stock is changed as a result of a stock dividend,
stock split, recapitalization, combination, subdivision, issuance of rights or
other similar corporate change, and unless the Board determines otherwise,
there shall be an automatic adjustment in (a) the aggregate number of shares of
CDI Stock which may be issued under the Plan, (b) the per individual annual
limitation set forth in Paragraph 3 above, and (c) the number of shares of CDI
Stock subject to, and the Option price of, any then outstanding Options.

        15. Certain Corporate Transactions.  If during the term of any Option,
CDI Corp. or any Subsidiary Company shall be merged into or consolidated with
or otherwise combined with or acquired by another person or entity, or there is
a divisive reorganization or a liquidation or partial liquidation of CDI Corp.,
CDI Corp. may (but shall not be required to) take any of the following courses
of action:

            (a) Not less than 10 days nor more than 60 days prior to any such
transaction, all Optionees shall be notified that their Options shall expire on
the 10th day after the date of such notice, in which event all Optionees shall
have the right to exercise all of their Options prior to such new expiration
date; or

            (b) CDI Corp. shall provide in any agreement with respect to any
such merger, consolidation, combination or acquisition that the surviving, new
or acquiring corporation shall grant options to the Optionees to acquire shares
in such corporation provided that the excess of the fair market value of the
shares of such corporation immediately after the consummation of such merger,
consolidation, combination or acquisition over the option price, shall not be
less than the excess of the Fair Market Value of CDI Stock over the exercise
price of Options, immediately prior to the consummation of such merger,
consolidation, combination or acquisition; or

            (c) CDI Corp. shall take such other action as the Board shall
determine to be reasonable under the circumstances in order to permit Optionees
and Eligible Directors to realize the value of rights granted to them under the
Plan.

        16.  Plan Not to Affect Relationship With the Company.  Neither the Plan
nor any Option shall confer upon any person any right to continue in the service
of the Company.

        17. Cancellation of Options and Repayment of Gains. Notwithstanding any
other provision of this Plan, the Board may, in its sole discretion and to the
extent allowed in an Optionee's Agreement, cancel the outstanding Options held
by such Optionee and/or require the Optionee to pay to the Company an amount
equal to any


<PAGE>
                                                                              66

gains derived from the exercise of any Options previously granted to and
exercised by such Optionee if the Board, in its sole discretion, determines that
such Optionee has entered into or intends to enter into competition with any
member of the Company.

        18. Shareholder Rights and Privileges.  An Optionee shall have no rights
as a shareholder with respect to any shares of CDI Stock covered by an Option
until the issuance of a stock certificate to the Optionee representing such
shares.

        19. Amendment.  The Board may at any time terminate the Plan or make
such changes therein as it shall deem advisable.  No outstanding Option shall be
affected by any such amendment without the written consent of the Optionee or
other person then entitled to exercise such Option.

        20. Securities Laws. The Committee shall make each grant under the Plan
subject to such conditions as shall cause both the grant and exercise of an
Option to comply with the then-existing requirements of Rule 16b-3 (or any
similar rule) of the Securities and Exchange Commission.

        21. Performance-Based Compensation. Unless otherwise provided by the
Committee in its discretion, it is intended that all compensation income
recognized by Eligible Employees as the result of the exercise of Options, or
the disposition of CDI Stock acquired on exercise of Options, shall be
considered performance-based compensation excludable from such Eligible
Employee's "applicable employee remuneration" pursuant to section 162(m)(4)(C)
of the Internal Revenue Code of 1986, as amended.

        22. General. Each Option granted shall be evidenced by an Agreement
containing such terms and conditions not inconsistent with the Plan as the
Committee may determine. The issuance of CDI Stock on the exercise of an Option
shall be subject to all of the applicable requirements of the Pennsylvania
Business Corporation Law and other applicable laws. Among other things, an
Optionee may be required to deliver an investment representation to the Company
in connection with any exercise of an Option or to agree to refrain from selling
or otherwise disposing of the CDI Stock acquired for a specified period of time.
