price. To the extent permitted under Regulation it of the Federal Reserve Board,

broker in a so-called "cashless exercise" whereby the broker sells the Option
shares and delivers cash sales proceeds to the Company in payment of the

unless and until shares of Stock are in fact issued to such person in connection
with the exercise of the Option. Nothing in this Option Agreement shall

terminate the Optionee's employment at any time, nor confer upon the Optionee
any right to continue in the employ of the Company or any Subsidiary.

     6. Stock-Reserve. The Company shall at all times during the term of this

Re:  Exercise of Non-Qualified Stock Option

I elect to purchase        shares of Common Stock of Acsys, Inc. pursuant to the
                   -------
Acsys, Inc. Non-Qualified Stock Option Agreement dated       and the Acsys, Inc.

Exercise Date, which will be as soon as practicable following the date this
notice and all other necessary forms and payments are received by the Company,

     On or before the Exercise Date, I will pay the full exercise price in the
form specified below (check one):

[ ] Cash Only: by delivering a certified or a cashier's check to Acsys, Inc. for

    my endorsement for shares of Acsys Stock that I have owned for at least six
    months. If the number of shares of Acsys Stock
<PAGE>
 
    represented by such stock certificate exceeds the number needed to pay the
    exercise price (based on the Fair Market Value of the Acsys Stock on the
    date of delivery), the Company will issue me a new stock certificate for
    the excess.

    months. If the number of shares of Acsys Stock represented by such stock
    certificate exceeds the number needed to pay the exercise price (based on
    the Fair Market Value of the Acsys Stock on the date of delivery), the
    Company will issue me a new stock certificate for the excess.

[ ] Cash From Broker: by delivering the purchase price from          a broker,
    ----------------                                       ----------
    dealer or other "creditor" as defined by Regulation it issued by the Board
    of Governors of the Federal Reserve System (the "Broker"). I authorize the

    Company from the Broker and to deliver such stock certificate directly to
    the Broker (or to any other party specified in the instructions from the

Please deliver the stock certificate to me (unless I have chosen to pay the
purchase price through a broker).

                                       Very truly yours,
