To Brokers, Dealers, Commercial Banks, Trust Companies and Other Nominees:

         Intelligent Systems Corporation, a Georgia corporation, has appointed
American Stock Transfer and Trust Co. to act as the Information Agent in
connection with its offer to purchase for cash, up to 1,000,000 shares of its
common stock, par value $0.01 per share, at the price of $5.25 per share, net to
the seller in cash, without interest, under the terms and conditions set forth
in its Offer to Purchase dated June 1, 2001, and in the related Letter of
Transmittal which together present the tender offer.

         All shares properly tendered before the expiration date (as defined in
Section 1 of the Offer to Purchase), and not properly withdrawn, will be
purchased by ISC at the purchase price, net to the seller in cash, without
interest, under the terms and conditions of the tender offer, including the odd
lot and proration provisions thereof. See Sections 1 and 2 of the Offer to
Purchase. Shares not purchased because of proration will be returned at ISC's
expense to the shareholders who tendered such shares as promptly as practicable
after the expiration date. ISC reserves the right, in its sole discretion, to
purchase more than 1,000,000 shares under the tender offer, subject to
applicable law.

         If, at the expiration date, more than 1,000,000 shares, or such greater
number of shares as ISC may elect to purchase in accordance with applicable law,
are properly tendered and not properly withdrawn, ISC will, under the terms and
conditions of the tender offer, accept shares for purchase first from "odd lot
holders" (as defined in Section 2 of the Offer to Purchase) who properly tender
all of their shares and then on a pro rata basis from all other shareholders
whose shares are properly tendered and not properly withdrawn.

         The tender offer is not conditioned on any minimum number of shares
being tendered. The tender offer is, however, subject to other conditions. See
Section 7 - Conditions of the Tender Offer, of the Offer to Purchase.

         For your information and for forwarding to your clients for whom you

enclosing the following documents:
