ITEM 2. ACQUISITION OR DISPOSITION OF ASSETS.
 
    THE CURRENT REPORT ON FORM 8-K CONTAINS FORWARD LOOKING STATEMENTS WITHIN
THE MEANING OF SECTION 27A OF THE SECURITIES ACT OF 1933, AS AMENDED (THE
"SECURITIES ACT") AND SECTION 21E OF THE SECURITIES EXCHANGE ACT OF 1934, AS
AMENDED, RELATED TO ZAMBA CORPORATION (F/K/A RACOTEK, INC.), A DELAWARE
CORPORATION ("ZAMBA"), AND ZAMBA'S ACQUISITION OF QUICKSILVER GROUP, INC., A
CALIFORNIA CORPORATION ("QUICKSILVER"), THAT MAY INVOLVE SUBSTANTIAL RISKS AND
UNCERTAINTIES. THESE UNCERTAINTIES INCLUDE RISKS RELATING TO THE INTEGRATION OF
ZAMBA AND QUICKSILVER. ACTUAL RESULTS AND DEVELOPMENTS THEREFORE MAY DIFFER
MATERIALLY FROM THOSE DESCRIBED OR INCORPORATED BY REFERENCE IN THIS REPORT. FOR
MORE INFORMATION ABOUT ZAMBA AND RISKS ARISING WHEN INVESTING IN ZAMBA, YOU ARE
DIRECTED TO ZAMBA'S MOST RECENT REPORTS ON FORM 10-K AND FORM 10-Q, AS FILED
WITH THE SECURITIES AND EXCHANGE COMMISSION (THE "COMMISSION").
 
    On July 6, 1998, an Agreement and Plan of Merger and Reorganization (the
"Original Agreement"), among Zamba, Quicksilver Acquisition Corp., a California
corporation ("Merger Sub") and QuickSilver was entered into and, on September 2,
1998, an addendum (the "Addendum") was added to the original agreement
(together, the Original Agreement and Addendum constitute the "Agreement").
Pursuant to the Agreement, QuickSilver merged with and into Merger Sub, the
separate existence of QuickSilver ceased and Merger Sub continued as the
surviving corporation. The terms of the Agreement, including the consideration
paid, were determined through arms' length negotiations between Zamba and
QuickSilver. Zamba is a customer care consulting company. QuickSilver is a
provider of software integration services.
 
    The merger of QuickSilver with and into Merger Sub (the "Merger") became
effective on September 22, 1998, at the time of the filing of a Certificate of
Merger with the California Secretary of State (the "Effective Time"). At the
Effective Time: (a) QuickSilver ceased to exist; (b) Merger Sub, the surviving
corporation in the Merger, continued to be a wholly-owned subsidiary of Zamba;
(c) Zamba paid $500,470 in cash from general corporate funds and $2,161,675 in
promissory notes and issued 2,337,992 shares of Common Stock in an exchange,
under Regulation D of the Securities Act, for all outstanding shares of
QuickSilver capital stock; and (d) the stock options and warrants of QuickSilver
outstanding at the Effective Time were converted into options and warrants of
Zamba. The Merger is intended to be a tax-free reorganization under the Internal
Revenue Code of 1986, as amended, and will be accounted for as a purchase. The
foregoing discussion regarding the Agreement and the Merger is qualified in its
entirety by reference to the Original Agreement and the Addendum, copies of
which are attached hereto as Exhibits 2 and 3, respectively, and which are
hereby incorporated by reference.
 
    The Merger will result in the integration of two companies that have
previously operated independently. As soon as practicable following the Merger,
Zamba intends to integrate certain aspects of the operations of QuickSilver.
However, there can be no assurance that Zamba will successfully integrate the
operations of QuickSilver with those of Zamba or that all of the benefits
expected from such integration will be realized. Any delays or unexpected costs
incurred in connection with such integration could have an adverse effect on
Zamba's business, operating or financial condition. Furthermore, there can be no
assurance that the operations, management and personnel of the two companies
will be compatible or that Zamba will not experience the loss of key personnel
and clients. There can be no assurance that combining the business of Zamba and
QuickSilver, even if achieved in an efficient and effective manner, will result
in combined results of operations and financial condition superior to what would
have been achieved by Zamba or QuickSilver independently. In addition, certain
costs are generally associated with transactions such as the Merger. While these
costs have not been currently identified, any such costs will adversely affect
operating results of Zamba in the period in which they are incurred. Finally,
the parties intend that the transaction will be eligible for tax-free treatment,
but failure to obtain such status could increase the costs of the transaction.

ITEM 5. OTHER EVENTS.
 
    As previously reported, the Company transferred certain wireless mobile
computing technology and assets to NextNet, Inc. ("NextNet"), a corporation
formed to develop this technology, which received $8 million in financing from
third-party investors as part of its initial capitalization. The Company
obtained 2,400,000 shares of Common Stock of NextNet in exchange for the
transfer of its wireless mobile computing technology, representing approximately
44% of the outstanding shares of NextNet. The press release issued by Racotek,
Inc. dated September 23, 1998 is incorporated by reference herein. The foregoing
discussion regarding NextNet is qualified in its entirety by reference to
Exhibits 5 through 9, which are hereby incorporated by reference.
 
    Pursuant to a Certificate of Ownership and Merger, which provides for the
merger of Zamba Corporation, a Delaware corporation and wholly owned subsidiary
of Racotek, Inc., filed with the Delaware Department of Corporations and
declared effective on October 5, 1998, the corporate name of Racotek, Inc. has
been changed to "Zamba Corporation." All agreements, actions, filings and
reports made after October 5, 1998 shall bear the name "Zamba Corporation." The
symbol for the Company's common stock as reported on the Nasdaq National Market
shall be "ZMBA."

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Stockholders
QuickSilver Group, Inc.
 
    In our opinion, the accompanying balance sheets and the related statements
of operations, of stockholders' equity and of cash flows, present fairly, in all
material respects, the financial position of QuickSilver Group, Inc. at December
27, 1996 and December 26, 1997, and the results of its operations and its cash
flows for each of the two years in the period ended December 26, 1997, in
conformity with generally accepted accounting principles. These financial
statements are the responsibility of the Company's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these statements in accordance with
generally accepted auditing standards which require that we plan and perform the
audit to obtain reasonable assurance about whether the financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for the opinion expressed
above.
 
    As discussed in Note 13, subsequent to December 26, 1997, the Company
entered into a definitive merger agreement with Racotek, Inc.

                         NOTES TO FINANCIAL STATEMENTS
 
1. COMPANY BACKGROUND:
 
    QuickSilver Group, Inc. (the "Company") is an information technology
professional services company. The Company provides solutions for improving
customer and technical support to companies in high technology industries
throughout the United States. The Company maintains offices in Cupertino,
California and Boston, Massachusetts.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
    BASIS OF PRESENTATION:
 
    The Company's fiscal year end is the 52 or 53 week period ending on the last
Friday in December. The years ended December 27, 1996 and December 26, 1997
contain 52 weeks.
 
    FINANCIAL INSTRUMENTS:
 
    The amounts reported for cash and cash equivalents, accounts receivable,
other assets, accounts payable and accrued liabilities approximate their fair
values due to their short maturities.
 
    USE OF ESTIMATES:
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
    CASH AND CASH EQUIVALENTS:
 
    The Company considers all highly liquid investments with original maturities
of three months or less to be cash equivalent.
 
    INTANGIBLE ASSETS:
 
    Intangible assets consists primarily of goodwill and a software license
acquired from a third party. Goodwill is the excess of net assets acquired in
business combinations over their fair value. Intangible assets are amortized on
a straight-line basis over a five-year period. Amortization expense was $19,000
and $54,000 for fiscal years 1996 and 1997, respectively. Amortization expense
of $54,000 for fiscal year 1997 included $35,000 resulting from the write-off of
a software license originally acquired in 1997.
 
    PROPERTY AND EQUIPMENT:
 
    Property and equipment are stated at cost. Depreciation is determined using
the straight-line method over the estimated useful lives of the assets which is
generally three years. Leasehold improvements and assets under capital leases
are amortized over the shorter of the asset's related lease term or estimated
useful life. Gains and losses on disposal of property and equipment are
recognized in the period the assets are disposed of.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
    REVENUE RECOGNITION:
 
    Revenues from consulting services include systems integration services and
training services. Revenues on variable rate contracts are recognized as the
services are performed and invoiced. Revenues on fixed rate contracts are
deferred and recognized ratably over the contract period in accordance with the
performance of the underlying services.
 
    ADVERTISING:
 
    The Company expenses advertising costs as they are incurred. Advertising
expense for fiscal years 1996 and 1997 approximated $41,000 and $68,000,
respectively.
 
    INCOME TAXES:
 
    The Company utilizes the asset and liability method of accounting for income
taxes whereby deferred taxes are determined based on the difference between the
financial statement and tax bases of assets and liabilities using enacted tax
rates in effect for the years in which the differences are expected to reverse.
Valuation allowances are established when necessary to reduce deferred tax
assets to the amount expected to be realized. Income tax expense represents
taxes payable for the current period, plus the net change in the deferred tax
assets and liabilities during the period.
 
    CERTAIN RISKS AND CONCENTRATIONS OF CREDIT RISK:
 
    The Company markets and sells its services primarily to end-users and to
independent software vendors in the software industry. The Company performs
ongoing credit evaluations of its customers' financial condition and does not
require collateral. The Company maintains an allowance for doubtful accounts
based upon the expected collectability of such receivables. At December 27,
1996, 54% of accounts receivable, were due from four customers. At December 26,
1997, 53% of accounts receivable were due from four customers.
 
    Four customers accounted for 13%, 13%, 11% and 10% of total revenues in
1996. Three customers accounted for 17%, 14% and 10% of total revenues in 1997.
 
    STOCK-BASED COMPENSATION:
 
    The Company accounts for stock-based compensation using the intrinsic value
method prescribed in Accounting Principles Board (APB) Opinion No. 25,
"Accounting for Stock Issued to Employees," and related interpretations. The
Company has elected to adopt the disclosure only provisions of Statement of
Financial Accounting Standards No. 123 (SFAS 123), "Accounting for Stock Based
Compensation," which requires pro forma disclosures in the financial statements
as if the measurement provisions of SFAS 123 had been adopted. Compensation cost
for stock options granted to non-employees is measured as the fair value of the
option at the date of grant. Such compensation costs, if any, are amortized on a
straight-line basis over the underlying option vesting terms.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
    RECENT ACCOUNTING PRONOUNCEMENTS:
 
    In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 130 (SFAS 130), "Reporting Comprehensive
Income." This Statement establishes requirements for disclosure of comprehensive
income and becomes effective for the Company for its fiscal year 1999, with
reclassification of earlier financial statements for comparative purposes.
Comprehensive income generally represents all changes in shareholders' equity
except those resulting from investments or contributions by shareholders. The
Company does not expect this pronouncement to materially impact the Company's
results of operations.
 
    In March 1998, the American Institute of Certified Public Accountants issued
Statement of Position 98-1 ("SOP 98-1") "Accounting for the Costs of Computer
Software Developed or Obtained for Internal Use." SOP 98-1 provides guidance for
determining whether computer software is internal-use software and on accounting
for the proceeds of computer software originally developed or obtained for
internal use and then subsequently sold to the public. It also provides guidance
on capitalization of the costs incurred for computer software developed or
obtained for internal use. The Company has not yet determined the impact, if
any, of adopting this statement. The disclosures prescribed by SOP 98-1 will be
effective for the Company's fiscal year 2000.

    LICENSE AGREEMENT:
 
    In August 1997, the Company entered into an agreement with Montreaux
Services, Inc. (Montreaux) whereby the Company was granted a perpetual,
exclusive right and license to use all of the proprietary information and trade
secrets belonging to Montreaux. Under the terms of the agreement, the Company
was required to pay a fixed licensing fee to Montreaux of $70,000 payable in six
equal monthly installments commencing September 1, 1997. In fiscal 1997, the
Company made three payments totaling $35,000 prior to verbally terminating the
agreement with Montreaux's principals. The Company expects to enter into a
formal termination agreement with Montreaux eliminating any further obligations
by either party under this arrangement.

Associates Ltd. in exchange for 80,000 shares of The Quicksilver Group, Inc.
common stock (valued at $105,000). The acquisition was accounted for as a
purchase. Accordingly, the purchase price was allocated to the acquired assets

goodwill which is being amortized over a period of five years, in accordance
with the Company's accounting policies.

10. SHAREHOLDERS' EQUITY:
 
    1995 STOCK APPRECIATION RIGHTS PLAN:
 
    In May 1995, the Company adopted the QSG Stock Appreciation Rights ("SAR")
Plan. The plan provided for the granting of SARs which permit the holders to
receive the excess of the fair value per share of common stock on the date a SAR
is exercised over the beginning fair value. Under this plan, the Board of
Directors may grant SARs at the fair value of the Company's common stock, as
determined by the Board of Directors, at the grant date. SARs granted under the
plan have a term of ten years and generally become exercisable with respect to
25% of the shares on the first anniversary of the vesting commencement date and
thereafter at the rate of 25% of the shares per year. At December 27, 1996,
302,000 shares were outstanding. During 1996, a pre-tax charge of $23,019 was
incurred related to SARs due to an increase in the value of the Company's stock
and the increased number of outstanding SARs. During 1997, 169,200 SARs were
issued to employees. In July 1997, the Company terminated the 1995 Stock
Appreciation Rights Plan and adopted the 1997 Stock Option Plan ("the Plan").
All SARs outstanding were terminated during fiscal 1997 and reissued as stock
option grants under the Plan. As discussed below, these stock options were
granted with exercise prices less than fair value.
 
    1997 STOCK OPTION PLAN:
 
    At December 26, 1997, the Company had reserved 500,000 shares of common
stock for issuance under it's Stock Option Plan. Under the Plan, the Board of
Directors may award options to employees, directors and consultants of the
Company. Incentive stock options may be granted at prices not less than 85% of
the value of the Company's common stock at the date of grant, as determined by
the Board of Directors. Options granted under the 1997 Stock Option Plan have a
term of ten years and become exercisable at least 20% per year over five years
from the date the options are granted. As discussed below, stock options granted
during 1997 were granted with exercise prices less than fair value.
 
    Activity under the Company's stock option plan is set forth below:

    DEFERRED STOCK COMPENSATION:
 
    The stock options issued to employees under the 1997 Stock Option Plan were
made at exercise prices below the estimated market value of the Company's common
stock at the date of grant. In accordance with the requirements of APB 25, the
Company has recorded deferred compensation for the difference between the
exercise price of the stock options and the fair value of the Company's stock at
the date of grant. This deferred compensation is amortized to expense over the
period during which the options become exercisable, generally over periods up to
four years. At December 26, 1997, the Company recorded deferred compensation
related to these options in the total amount of $423,250, of which $45,477 was
amortized to expense during fiscal 1997.
 
    EMPLOYEE STOCK PURCHASE PLAN:
 
    During 1996, the Company adopted an Employee Stock Purchase Agreement (the
Agreement) under which 60,000 shares of common stock have been reserved for
issuance. The Agreement allows employees to receive a portion of their bi-annual
profit sharing payments in common stock. Employees can elect to take their
profit-sharing contribution in the form of cash, stock or a combination of cash
and stock. Under the Agreement, 31,596 shares of common stock with an estimated
market value of $45,000 were issued in fiscal year 1997.
 
    PRO FORMA STOCK COMPENSATION:
 
    Had compensation cost been determined based on the fair value at the grant
date for awards 1997 consistent with the provisions of SFAS 123, the Company's
net income for the year ended December 1997 would have been as follows (IN
THOUSANDS):
 


                                                                                          1997

10. SHAREHOLDERS' EQUITY: (CONTINUED)
 
    In accordance with the provisions of SFAS 123, the fair value of each option
is estimated using the minimum value option pricing method allowable for
non-public companies and using the following assumptions for option grants
during fiscal year 1997; dividend yield of 0%, risk-free interest rates of
between 5.72% to 5.98% at the date of grant, and an expected term of periods up
to four years.
 
    Of the options granted during fiscal year 1997, options to purchase 147,000
shares of the Company's common stock, with a weighted-average exercise price of
$2.25 per share and a weighted-average fair value of $0.15 per share, were
granted with exercise prices equal to the estimated fair value at the date of
grant; 303,200 options with a weighted-average exercise price of $0.85 and a
weighted-average fair value of $0.09 per share were granted with an exercise
price below the estimated fair value at the date of grant.

                             ZAMBA AND QUICKSILVER
               UNAUDITED PRO FORMA CONDENSED FINANCIAL STATEMENTS
 
    The accompanying unaudited pro forma condensed financial statements give
effect to the merger of Zamba Corporation (f/k/a Racotek, Inc.) and QuickSilver
Group, Inc., a California corporation, ("QuickSilver"), using the purchase
method of accounting. The unaudited pro forma condensed financial statements are
derived from and should be read in conjunction with Zamba Corporation's (Zamba)
historical financial statements provided in Zamba's most recent reports on Form
10-K and Form 10-Q, and QuickSilver's financial statements which are included in
Item 7(a) of this Form 8-K, and in the notes hereto. The unaudited pro forma
condensed balance sheet combines Zamba's June 30, 1998 unaudited condensed
balance sheet with QuickSilver's June 30, 1998 unaudited condensed balance
sheet. The unaudited pro forma condensed statements of operations combine
Zamba's historical condensed statements of operations for fiscal year 1997 and
the unaudited six-month period ended June 30, 1998 with the corresponding
QuickSilver historical condensed statements of operations for fiscal year 1997
and the six-month period ended June 30, 1998, respectively. The pro forma
adjustments have been applied to the financial information derived from the
financial statements of Zamba and QuickSilver to account for the merger as a
purchase; accordingly, assets acquired and liabilities assumed are reflected at
their estimated fair values which are subject to further refinement.
 
    The unaudited pro forma condensed financial statements have been prepared on
the basis of assumptions described in the notes thereto and include assumptions
relating to the allocation of the consideration paid for the assets and
liabilities of QuickSilver based on preliminary estimates of their fair value.
The actual allocation of such consideration may differ from that reflected in
the unaudited pro forma condensed financial statements after certain decisions
are made, and after certain procedures to be performed after the closing of the
merger are completed. In the opinion of Zamba, all adjustments necessary to
present fairly such unaudited pro forma condensed financial statements have been
made based on the proposed terms and structure of the merger.
 
    The unaudited pro forma information is presented for illustrative purposes
only and is not necessarily indicative of the operating results or financial
position that would have occurred if the merger had been consummated at the
beginning of the periods presented, nor is it necessarily indicative of future
operating results or financial position.

         ZAMBA CORPORATION (F/K/A RACOTEK, INC.) AND QUICKSILVER GROUP
 
       NOTES TO THE PRO FORMA CONDENSED BALANCE SHEET AS OF JUNE 30, 1998

    consists of the following:
 

                                                                   
Issuance of 2,337,992 restricted common shares......................  $   3,397
Issuance of convertible promissory notes............................      2,162
Issuance of stock options with exercise prices below market value...        506
Issuance of warrant with exercise price below market value..........        881
Cash paid, including transaction costs..............................        800
                                                                      ---------
                                                                      $   7,746
                                                                      ---------
                                                                      ---------

 
        The purchase price will increase by $257 if the stock options granted to
    former QuickSilver employees vest. At the time of vesting, the purchase
    price increase will be reflected as an increase in additional paid-in
    capital and goodwill. The above purchase price computation assumes a fair
    value of $1.45 per share of common stock, which reflects a 25% discount, due
    to restrictions on the trading of these shares.
 
(B) To eliminate the QuickSilver Group's historical equity.
 
(C) To increase the carrying value of the QuickSilver debt to its estimated fair
    value.
