To Our Clients:

        Enclosed for your consideration are the Offer to Purchase, dated October 10, 2003, the letter of transmittal, and other related materials, in connection with the offer by Collins Industries, Inc., a Missouri corporation, to purchase for cash up to 1,100,000 shares of its common stock, par value $0.10 per share, at a price not greater than $4.50 nor less than $3.60 per share, net to the seller in cash, without interest, as specified by shareholders tendering their shares.

        Given the prices specified by tendering shareholders and the number of shares tendered and not properly withdrawn, Collins Industries, Inc. will select the lowest purchase price between $3.60 and $4.50 net per share in cash, without interest, that will allow it to purchase 1,100,000 shares, or, if a lesser number of shares are properly tendered, all shares that are properly tendered. All shares acquired in the tender offer will be purchased at the same price.

        Collins Industries, Inc.'s offer is being made upon the terms and subject to the conditions set forth in its Offer to Purchase, dated October 10, 2003, and in the related letter of transmittal, as either may be amended and supplemented from time to time.

        Only shares properly tendered at prices equal to or below the purchase price and not properly withdrawn will be purchased. However, because of the proration provisions described in the Offer to Purchase, all of the shares tendered at or below the purchase price may not be purchased if more than 1,100,000 shares are properly tendered. All shares tendered and not purchased, including shares tendered at prices above the purchase price and shares not purchased because of proration or the conditional tender procedures, will be returned at Collins Industries, Inc.'s expense as soon as practicable following the expiration date.

        Collins Industries, Inc. reserves the right, in its sole discretion, to purchase more than 1,100,000 shares pursuant to the offer, subject to applicable law. Upon the terms and conditions of Collins Industries, Inc.'s offer, if more than 1,100,000 shares are properly tendered at prices equal to or below the purchase price and not properly withdrawn, Collins Industries, Inc. will purchase properly tendered shares in the following order:

•

First, all shares properly tendered and not properly withdrawn by any "odd lot holder" (as defined below) who:



(i)

tenders all shares owned (beneficially or of record) by the odd lot holder at a price equal to or below the purchases price (tenders of less than all the shares owned will not qualify for this preference); and



(ii)

completes the section entitled "Odd Lots" in the letter of transmittal and, if applicable, in the notice of guaranteed delivery;

•

Second, all shares properly tendered and not properly withdrawn by any holder who would become an "odd lot holder" (as defined below) as a result of any proration and who tenders all shares owned by the holder at a price equal to or below the purchase price; and



•

Third, after the purchase of all the shares properly tendered by odd lot holders and by those who would become odd lot holders as a result of proration, all other shares properly tendered at prices equal to or below the purchase price, on a pro rata basis with appropriate adjustments to avoid purchases of fractional shares and subject to the conditional tender procedures described in Section 6 of the Offer to Purchase.
