                          DEREGISTRATION OF SECURITIES

         The 4,957,937 shares of common stock, par value $0.01 per share, (the
"Shares"), of Zamba Corporation (the "Company") registered on the Registration
Statement on Form S-3 (File No. 333-66999) (the "Registration Statement") were
issued as follows: (a) (i) 2,337,992 Shares, (ii) notes with an aggregate
principal value of $2,161,674.82 that are convertible into Shares at their
current market value, and (iii) warrants to purchase 462,247 Shares at an
exercise price of $0.0066623 per Share, issued in connection with the Company's
merger with QuickSilver Group, Inc. ("QuickSilver') (the "Merger"), and (b)
1,000,000 shares of Series A Junior Participating Preferred Stock, which are
convertible into 1,000,000 Shares, were issued and sold in a private placement.
Pursuant to these transactions, the Company agreed to register the Shares under
the Securities Act of 1933, as amended (the "Securities Act"), and use its best
efforts to cause the Registration Statement covering the Shares to remain
effective until such time as the holders of the Shares may sell the Shares
without registration pursuant to Rule 144 under the Securities Act. As of the
date hereof, a total of 3,353,536 shares have been sold pursuant to the
Registration Statement, and each of the holders may now sell the Shares without
registration pursuant to Rule 144 under the Securities Act, subject to
compliance with the requirements set forth therein. Accordingly, the Company
hereby amends the Registration Statement to deregister 1,604,401 unsold Shares
under the Registration Statement. The Company intends to carry forward any
excess registration fees it paid in connection with the Registration Statement
to be used for future registrations.
