                            STOCK PURCHASE AGREEMENT


         This Stock Purchase Agreement (the "Agreement") is entered into as of
_______________ ___, 1999, by and between Sirmon Commercial Finance, L.L.C.
("Seller") and KBK Capital Corporation (the "Purchaser").

                                    RECITALS

         WHEREAS, Seller is the owner of 483,795 shares (the "Stock") of Common
Stock, par value $.01 per share, of the Purchaser;

         WHEREAS, the Purchaser desires to acquire from Seller, and Seller
desires to sell to the Purchaser, the Stock;

         WHEREAS, Seller is making certain representations, warranties,
covenants and indemnities herein as an inducement for the Purchaser to enter
into this Agreement; and

         WHEREAS, capitalized terms not otherwise defined herein shall have the
meanings set forth in Exhibit A.

         NOW, THEREFORE, in consideration of the respective representations,
warranties and covenants contained herein and other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged,
the parties hereto hereby agree as follows:


                                   ARTICLE I
                      SALE AND PURCHASE OF STOCK; CLOSING

         1.1      SALE AND PURCHASE OF INITIAL SHARES. Subject to the terms and
conditions of this Agreement, Seller does hereby sell, assign, transfer and
deliver to the Purchaser, and the Purchaser does hereby purchase and acquire
from Seller an aggregate of 100,000 shares of the Stock (the "Initial Shares").

         1.2      SALE AND PURCHASE OF DEFERRED SHARES. Subject to the terms
and conditions of this Agreement, Seller hereby agrees to sell, assign,
transfer and deliver to the Purchaser, and the Purchaser hereby agrees to
purchase and acquire from Seller an aggregate of 383,795 shares of the Stock in
the amounts and on the dates set forth on Exhibit B (the "Deferred Shares").

         1.3      PURCHASE OF ADDITIONAL SHARES. At each Subsequent Closing (as
hereinafter defined), the Purchaser shall have the option, in its sole
discretion, to purchase a greater number of shares of Stock than that set forth
on Exhibit B with respect to the date of such Subsequent Closing (the

the same as that set forth on Exhibit B for the shares of Stock to be purchased
on such Subsequent Closing. If such greater number of shares is purchased, the
number of the remaining shares to be purchased at each Subsequent Closing
thereafter will be reduced on a pro rata basis, such that the aggregate number
of shares of Stock purchased by the Purchaser pursuant to this Agreement is
483,795.
