on March 31, 1999, for the purposes of presenting the pro forma balance sheet.

The Unaudited Pro Forma Condensed Consolidated Financial Statements are based
on, and should be read in conjunction with, the audited historical financial
statements and the notes thereto of CBT included in the fiscal 1998 Annual
Report on Form 10-K, as amended by Form 10-K/A, and the unaudited financial

adjusted to reflect their fair values in the pro forma condensed consolidated
balance sheet as of January 31, 1999. The effects resulting from these
adjustments have been reflected in the pro forma condensed consolidated
statements of operations. The pro forma adjustments include, in the opinion of
management, all adjustments necessary to give pro forma effect to the
acquisition as though such transaction had occurred on January 1, 1998 for the
purpose of presenting the pro forma statements of operations and on March 31,
1999 for the purposes of presenting the pro forma balance sheet.

The unaudited pro forma consolidated financial information is not necessarily
indicative of how the Company's balance sheet and results of operations would
have been presented had the transaction referenced above actually been
consummated at the assumed dates, nor is it necessarily indicative of
presentation of the Company's balance sheet and results of operations for any
future period.

(1)  The per share data has been restated to reflect the effects of the Ordinary
     Share Split (i) and the Knowledge Well Share Split (ii).

     (i)  On May 22, 1998, CBT effected a split of each of its issued and
          outstanding ordinary shares of IR37.5p into four ordinary shares of
          IR9.375p, "Ordinary Share Split". As a consequence of this ordinary
          share split, each American Depositary Share represents and is
          exchangeable for one ordinary share.

     (ii) On August 31, 1998, Knowledge Well Limited effected a split of each of
          its issued and outstanding ordinary shares of $1.00 into four ordinary
          shares of $0.25 each, "Knowledge Well Share Split".

  NOTES TO THE UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS


The unaudited pro forma condensed consolidated financial statements have been
prepared in accordance with generally accepted accounting principles in the
United States after eliminating all material intercompany accounts and

purchase method of accounting.

The purchase price of Knowledge Well is $60.2 million and has been allocated as

                                                          =======

The purchase consideration has been arrived at by calculating the fair market
value of the shares to be issued and the fair value of the options using
a Black-Scholes option pricing model. The fair market value per share used in
the valuation was $12.93, which was CBT's average share price for the period
beginning five days prior to, and ending five days following, the announcement
of the acquisition.

The following pro forma adjustments have been recorded to reflect the
acquisition:

Condensed Consolidated Balance Sheet - adjustments to reflect the occurrence of
the acquisition on March 31, 1999

(a)  The issuance of 4.8 million CBT ordinary shares for the issued and
     outstanding ordinary shares of Knowledge Well at a purchase consideration
     of $60.2 million. The ordinary shares of CBT Group PLC will increase by
     approximately $605,000 and Additional Paid In Capital will increase by the
     remainder of the purchase consideration, approximately $59.6 million.

                                       7


(b)  The $5.9 million of acquired in-process research and development will be
     written off to expense in the three months ended June 30, 1999, the period
     in which the closing of the acquisition occurred. This write off of in-
     process research and development is not reflected in the Unaudited Pro
     Forma Consolidated Statements of Operations as pro forma adjustments are
     limited to those events that are expected to have a continuing impact.

     The $5.9 million of acquired in-process research and development represents
     our management's estimate of the current fair value of those specifically
     identified Knowledge Well research and development projects for which
     technological feasibility has not been established and for which
     alternative future uses do not exist.  In estimating such current fair
     value, management considered the estimated future after-tax cash flows
     attributable to these projects, which were then discounted to present value
     utilizing appropriate discount rates commensurate with the risks of
     reaching technological feasibility, completing the in-process projects, and
     achieving the estimated cash flows (the discount rate was 25%).


(c)  Elimination of Knowledge Well pre acquisition shareholder's equity, as
     follows:

     The following are the assumptions used in determining the method and term
     of amortization of each of the intangibles noted above:

     (i)   The assembled workforce intangible will be amortized on a straight-
           line basis over a period of five years. The assembled workforce has
           been allocated a useful life of five years based on an expected
           employee turnover rate of 20% per year, which is a rate consistent
           with historical turnover rates for CBT employees;

     (ii)  The Kansas State University license agreement intangible will be
           amortized on a straight-line basis over a period of ten years. We
           have conservatively allocated a useful life of ten years to this
           license based on its initial ten-year term;

     (iii) The Hamilton College license agreement intangible will be amortized
           on a straight-line basis over a period of five years. We have
           conservatively allocated a useful life of five years to this license
           based on its initial five year term;

     (iv)  The implied goodwill will be amortized on a straight-line basis over
           a period of ten years. The goodwill has been allocated a useful life
           of ten years consistent with the period allocated to the Kansas State
           University license, which is the most significant of the acquired
           intangibles.


(i)  Amortization of goodwill and other identifiable assets are non-tax
     deductible.


The actual financial position and results of operations may differ from the pro
forma amounts reflected herein because of various factors, including, without
limitation, access to additional information, changes in value and changes in
operating results between the date of preparation of the unaudited pro forma
consolidated financial information and the date on which the acquisition closes.
However, in the opinion of management any final adjustments will not be material
to the future financial position and/or results of operation.
