Information About the Plan

ELIGIBILITY AND ENROLLMENT

1. How does a Kelly Services shareholder enroll in the Plan?

the Plan simply by completing and returning an Authorization Form.

2. I already own shares, but they are held by my bank or broker and
registered in "street name". How can I participate?

bank or broker to have at least one share registered directly in your name in
order to be eligible to participate. Once the shares are registered in your

5. Who may participate in the Plan?

All U.S. citizens are eligible to participate, whether or not they are currently

ADDITIONAL INVESTMENTS

6. What are the minimum and maximum amounts for additional investments?

The minimum amount for additional investments is $50.00 and the maximum amount
is $100,000.00 during any calendar year.

7. How do I make an additional investment?

You may send a check or money order payable in U.S. dollars to Kelly Services
Shareholder Investment Plan. Checks must be drawn against a U.S. bank or U.S.
bank affiliate. Cash and third-party checks are not allowed. Checks or money
orders must be accompanied by the appropriate section of your account
statement and mailed to The Kelly Services Shareholder Investment Plan, c/o
Mellon Bank, N.A., P.O. Box 3315, South Hackensack, NJ 07606-3315.

8. May I have additional investments automatically deducted from my bank
account?

Yes. You may authorize monthly automatic deductions from an account at a
financial institution that is a member of the National Automated Clearing
House Association.

 .    To initiate this service, you must send an Authorization Form, with the
     "Automatic Deduction Service" section completed, to the Plan Administrator.
 .    To change any aspect of the instruction, you must send a revised
     Authorization Form, with the "Automatic Deduction Service" section
     completed, to the Plan Administrator.
 .    To terminate the deductions, you must notify the Plan Administrator in
     writing.

Initial set-up, changes and terminations to the automatic deduction instructions
will be made as soon as practicable. Once effective, funds will be deducted from
your designated account on the 15th day of each month, or the next business day
if the 15th is not a business day.

9. Will I be charged fees for additional investments?

Yes. For any investment made by check or money order, an investment fee of $5.00
will be deducted at the time of the investment. An investment fee of $2.00 per

per share, which includes brokerage commissions.

                                        5



10. How are payments with "insufficient funds" handled?

If the Plan Administrator does not receive a payment because of insufficient
funds or incorrect draft information, the requested purchase will be deemed
void, and the Plan Administrator will immediately remove from your account any
shares purchased in anticipation of receiving such funds. If the net proceeds
from the sale of such shares are insufficient to satisfy the balance of the
uncollected amounts, the Plan Administrator may sell additional shares from your
account as necessary to satisfy the uncollected balance.

In addition, an "insufficient funds" fee of $25.00 will be charged. The Plan
Administrator may place a hold on the Plan account until the "insufficient
funds" fee is received from you, or may sell shares from your account to satisfy
any uncollected amounts.

11. When will shares be purchased?

The Plan Administrator will buy shares on Friday of each week (or the next
business day) if your funds are received no later than two business days before
that day.

12. What is the price of shares purchased under the Plan?

The purchase price for shares purchased by the Plan Administrator in the open
market will be the average weighted price per share paid by the Plan
Administrator for all purchases made that week for Plan participants. The
purchase price for shares purchased from or sold to Kelly Services will be the
average of the high and low sales price reported on the Nasdaq National Market
for the day of the transaction.

For automatic monthly purchases, shares will be purchased during the week after
the week of the 15th, beginning on Friday of that week, if your enrollment
material is received by the last business day of the previous month.

The Plan Administrator will use your investment to purchase as many full shares
as possible and will use any amount remaining to purchase a fraction of a share.

DIVIDENDS

13. Must my dividends be reinvested automatically?

No. You may elect partial or no reinvestment of your dividends by completing the
appropriate form obtained from the Plan Administrator. Unless you make an
election, all cash dividends on shares you hold outside of the Plan will be paid
to you, and dividends on shares in your Plan account will be reinvested
automatically in additional shares of Kelly Services Class A Common Stock. If
you choose partial investment, you must identify the percentage of shares in
your account on which you would like to receive cash payments for dividends.

                                        6



14. When will my dividends be reinvested and at what price?

The reinvestment of your dividends will generally be completed within five
business days of the dividend payment date. The price of shares purchased with
the dividends will be the weighted average price of all shares purchased with
reinvested dividends.

SOURCE OF STOCK

15. What is the source of Kelly Services stock purchased through the Plan?

At Kelly Services' option, share purchases will be made in the open market or
directly from Kelly Services. Share purchases on the open market may be made on
any stock exchange where Kelly Services Class A Common Stock is traded or by
negotiated transactions on such terms as the Plan Administrator may reasonably
determine. Neither Kelly Services nor any participant will have any authority or
power to direct the date, time or price at which shares may be purchased by the
Plan Administrator.

SALE OF SHARES

16. How do I sell my shares?

You can sell some or all of the Plan shares you hold in book-entry form by
providing written instructions to the Plan Administrator. Each account statement
you receive will have a form for this purpose. You can also sell your shares by
calling the Plan Administrator.

The Plan Administrator will sell shares daily. The sale price for your shares
will be the average weighted price per share received by the Plan Administrator
for all sales made that day for Plan participants. A $15.00 service charge and a
service fee of $.12 per share, which includes brokerage commissions, will be
deducted from your sale proceeds.

Please note that the Plan Administrator is not able to accept instructions to
sell on a specific day or at a specific price.

If you prefer, you can withdraw shares from the Plan, at no cost to you, and
sell them through a broker of your own choosing. Shares will normally be mailed
to you within five business days of receipt of your instructions. If you sell a
portion of your shares, the Plan Administrator will continue to reinvest the
dividends on the percentage of shares previously authorized by you.

HOW SHARES ARE HELD

17. How does the safekeeping service (book-entry shares) work?

All shares of Kelly Services stock that are purchased through the Plan will be
held by the Plan Administrator and registered in book-entry form in your Plan
account on the records of the Plan Administrator. If you hold Kelly Services
Class A Common Stock certificates outside the Plan you may also, at any time,
deposit those certificates for safekeeping with the Plan Administrator,

                                        7



and the shares represented by the deposited certificates will be included in
book-entry form in your Plan account.

18. How do I deposit my Kelly Services stock certificates with the Plan
Administrator?

To deposit certificates into the Plan, you should send your certificates, by
registered and insured mail, to the Plan Administrator at P.O. Box 3315, South
Hackensack, NJ 07606-3315, with written instructions to deposit those shares
in your Plan account. The certificates should not be endorsed and the assignment
section should not be completed.

19. Are there any charges associated with this custodial service?

No. There is no cost to you either for having the Plan Administrator hold the
shares purchased for you through the Plan or for having the Plan Administrator
deposit the stock certificates you hold into your account.

20. How can I receive a stock certificate?

Normally, stock certificates for shares purchased under the Plan will not be
issued; rather shares will be registered in the name of the Plan Administrator
or its nominee and credited to your Plan account. However, you may request a
stock certificate by indicating your preference on the stub attached to your
account statement and forwarding it to the Plan Administrator. There is no
charge for this service. Stock certificates for fractional shares will not be
issued under any circumstances.

TRANSFERS OF SHARES

21. Can I transfer shares that I hold in the Plan to someone else?

Yes. You may transfer ownership of some or all of your Plan shares by sending
the Plan Administrator written transfer instructions. Your signature must be
"Medallion Guaranteed" by a financial institution. Most banks and brokers
participate in the Medallion Guarantee program. The Medallion Guarantee program
ensures that the individual signing is in fact the owner of the participant's
account.

You may transfer shares to new or existing Kelly Services shareholders. However,
a new Plan account will not be opened for a transferee as a result of a transfer
of less than one full share. If you are opening a new Plan account for a
transferee, you must include an Authorization Form with the transfer
instructions. If no indication is given, the new Plan account will be coded for
full dividend reinvestment.

                                        8



WITHDRAWAL FROM THE PLAN

22. How do I close my Plan account?

You may terminate your participation in the Plan either by giving written notice
to the Plan Administrator or by completing the appropriate section of your
account statement and returning it to the Plan Administrator. Upon termination,
you must elect either to receive a certificate for the number of whole shares
held in your Plan account and a check for the value of any fractional shares, or
to have all of the shares in your Plan account sold for you as described above
and pay applicable fees and commissions.

The Plan Administrator will send you your proceeds, without interest, or your
certificates as soon as is practicable. If a notice of withdrawal is received on
or after the record date, but before the related dividend payment date, the Plan
Administrator will not process your request until after the dividend
reinvestment has posted to your account. Thereafter, cash dividends on shares
you physically hold will be paid out to you and not reinvested in Kelly Services
Class A Common Stock.

ADMINISTRATION

23. Who administers the Plan?

The Plan is administered by Mellon Bank N.A., the service provider for Mellon
Investor Services, Kelly Services' stock transfer agent. As Plan Administrator,
Mellon acts as agent for Plan participants and keeps records, sends statements
and performs other duties relating to the Plan.

Purchase and sales of Kelly Services Class A Common Stock under the Plan are
made by an independent broker-dealer acting as purchasing agent for Plan
participants. To the extent required by applicable law in certain jurisdictions,
shares offered under the Plan are offered through an independent broker-dealer.

24. How do I contact the Plan Administrator?

To request enrollment packages or for other questions, please call
(866) 249-2607

         or write to:
                  The Kelly Services Shareholder Investment Plan
                  c/o Mellon Bank N.A.
                  P.O. Box 3315
                  South Hackensack, NJ 07606-3315

         or refer to the Plan Administrator's website:
                  www.melloninvestor.com

                                        9



When communicating with the Plan Administrator, you should have available your
account number and taxpayer identification number.

25. What kind of reports will be sent to participants in the Plan?

You will receive a quarterly statement of account activity. Supplemental account
statements will be provided for any month in which you make a cash investment or
deposit or transfer or withdraw shares. You will also receive transaction
statements promptly after each sale of shares under the Plan. You should retain
these statements in order to establish the cost basis of shares purchased under
the Plan for income tax and other purposes.

ADDITIONAL INFORMATION

26. How would a stock split or stock dividend affect my account?

Any shares resulting from a stock split or stock dividend paid on shares held in
custody for you by the Plan Administrator will be credited to your book-entry
position. Of course, you may request a certificate at any time for any or all of
your shares.

27. Can I vote my Plan shares?

Under the Plan, participants may purchase only shares of Kelly Services Class A
Common Stock. As a general rule, shares of Class A Common Stock are non-voting.
As a result, you will generally not be sent a proxy statement in connection with
meetings of Kelly Services shareholders, including the annual meeting, and will
not be entitled to vote at those meetings.

Under the Delaware General Corporation Law, however, there are certain
conditions where shares of Class A Common Stock would have a right to vote.
Please refer to the Section below entitled "Description of Capital Stock Voting"
for more information on the limited voting rights of shares of Class A Common
Stock. In that case, you will be sent a proxy statement, together with a proxy
card. This proxy card, when duly signed and returned, will be voted as you
indicate. Fractional shares will be aggregated and voted in accordance with the
participant's directions. If the proxy card is not returned or if it is returned
unsigned, the shares will not be voted.

28. Can the Plan be changed?

We may add to, modify or discontinue the Plan at any time. We will send you
written notice of any significant changes.

Upon discontinuance of the Plan, we will return to you any uninvested automatic
deductions from your bank account, any uninvested optional cash investments or
initial investment, issue free of charge a certificate for full shares credited
to your account and pay you in cash for any fractional shares credited to your
account.

                                       10



29. What are the responsibilities of Kelly Services and the Plan
Administrator?

Neither Kelly Services nor the Plan Administrator, Mellon Bank N.A., will be
liable for any act, or for any failure to act as long as they have made good
faith efforts to carry out the terms of the Plan, as described in this
Prospectus and on the forms that accompany each investment or activity.

Participants should recognize that neither Kelly Services nor the Plan
Administrator can promise a profit or protect against a loss on the Class A
Common Stock purchased under the Plan.

Although the Plan provides for the reinvestment of dividends, the declaration
and payment of dividends will continue to be determined by Kelly Services Board
of Directors at its discretion, depending upon future earnings, the financial
condition of Kelly Services and other factors. The amount and timing of
dividends may be changed, or the payment of dividends terminated, at any time
without notice.

FEDERAL INCOME TAX CONSEQUENCES

You should consult with your tax advisor for a complete analysis of the tax
consequences of participating in the Plan. Cash dividends reinvested under the
Plan will be taxable for U.S. Federal income tax purposes as having been
received by you even though you have not actually received them in cash. You
will receive an annual statement from the Plan Administrator indicating the
amount of reinvested dividends reported to the U.S. Internal Revenue Service as
dividend income.

You will not realize a gain or loss for U.S. Federal income tax purposes upon a
transfer of shares to the Plan or the withdrawal of whole shares from the Plan.
You will, however, generally realize a gain or loss when shares are sold. The
amount of gain or loss will be the difference between the amount that you
receive for the shares sold and your tax basis thereof. In order to determine
the tax basis for shares in your account, you should retain all account and
transaction statements.

Plan participants who are non-resident aliens or non-U.S. corporations,
partnerships or other entities generally are subject to a withholding tax on
dividends paid on shares held in the Plan. The Plan Administrator is required to
withhold from dividends paid the appropriate amount determined in accordance
with Internal Revenue Service regulations. Where applicable, this withholding
tax is determined by treaty between the U.S. and the country in which the
participant resides. In addition, dividends paid on shares in Plan accounts are
subject to the backup withholding provisions of the Internal Revenue code.
Accordingly, the amount of any dividends, net of the applicable withholding tax,
will be credited to participant Plan accounts for investment in additional
shares of Kelly Services Class A Common Stock.

USE OF PROCEEDS

Kelly Services will receive proceeds from the purchase of Class A Common Stock
pursuant to the Plan only to the extent that such purchases are made directly
from it, and not from open

                                       11



market purchases by the Administrator. Proceeds received by Kelly Services (the
amount of which cannot be estimated) will be used for general corporate
purposes.

be declared unless the Board of Directors at the same time declares a cash
dividend on the shares of the Class A Common Stock at a rate which is not less
than the rate of the cash dividend payable on the shares of the Class B Common
Stock (but a cash dividend may be declared on the Class A Common Stock without
declaring a cash dividend on the Class B Common Stock), and (2) no dividend
payable in shares of the Class B Common Stock can be declared on the Class A

Preemptive Rights.

Holders of Class B Common Stock have the preemptive right to purchase additional

convertible into voting stock) issued at anytime by Kelly Services. Holders of
Class A Common Stock do not have preemptive rights to purchase additional
securities if Kelly Services issues additional securities.

INDEMNIFICATION OF DIRECTORS AND OFFICERS

Section 145 of the General Corporation Law of the State of Delaware and the

Services pursuant to the foregoing provisions, Kelly Services has been informed
that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Securities Act of
1933 and is therefore unenforceable.
