If you choose to submit a check, please make sure to include the contribution form from your Program statement and mail it to the address specified on the statement.

Will I be charged fees for additional investments? No. Any service fees or brokerage fees for purchases after the initial purchase will be paid for by Kelly Services. 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 $35.00 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 one business day 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 one week 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 two 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? If you own Kelly Services, Inc. Class A common stock in certificate form, you may deposit your certificates for those shares with the Administrator, free of charge. The Administrator will provide mail loss insurance coverage for certificates with a value not exceeding $100,000 in any one shipping package that is mailed to its address at 85 Challenger Road, Ridgefield Park, NJ 07660 by USPS registered mail or by any of the following overnight couriers: Airborne, DHL, Emery, ExpressMail, FedEx, Purolator, TNT and UPS. Note: Mail loss insurance covers only the replacement of shares of stock and in no way protects against any loss resulting from fluctuations in the value of such shares. 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.

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.
