Item 2.  Acquisition or Disposition of Assets
         ------------------------------------

         On June 18, 1999, CBT Group PLC, a public limited company organized
under the laws of the Republic of Ireland ("CBT"), closed its acquisition of
Knowledge Well Group Limited and Knowledge Well Limited, two private companies
formed under the laws of Ireland (collectively, "Knowledge Well"), pursuant to
the terms of a Share Purchase Agreement, dated as of November 30, 1998 as
amended and restated as of March 30, 1999 (the "Share Purchase Agreement"),
among CBT, Knowledge Well and the shareholders of Knowledge Well (the "Share
Exchange").

         To effect the acquisition, CBT is issuing CBT Ordinary Shares to the
shareholders of Knowledge Well in exchange for their ordinary shares of
Knowledge Well.  In addition, CBT has assumed the obligations of Knowledge Well
under all outstanding options to purchase ordinary shares of Knowledge Well such
that all such options are exercisable for CBT Ordinary Shares.  As a result, CBT
is issuing to the shareholders of Knowledge Well an aggregate of 4,375,574 CBT
Ordinary Shares (each represented by one American Depositary Share).  If all
assumed options vest and are exercised, CBT will issue to the option holders of
Knowledge Well an additional 461,635 CBT Ordinary Shares (each represented by
one American Depositary Share) in exchange for payment by the option holders of
the aggregate option exercise price.  As a result, CBT could issue a total of as
many as 4,837,209 shares in connection with the Share Exchange.  The number of
CBT Ordinary Shares issuable in exchange for each Knowledge Well ordinary share
(the "Exchange Ratio") was equal to the quotient obtained by dividing (x)
4,837,209 by (y) the sum of (1) the total number of Knowledge Well ordinary
shares in issue immediately prior to the closing of transaction plus (2) the
total number of shares of Knowledge Well of any class issuable upon exercise of
all options, warrants and similar rights outstanding immediately prior to the
closing of the Share Exchange.

    In connection with the Share Exchange, CBT deposited 402,000 of the CBT
Ordinary Shares (the "Escrow Shares") into an escrow fund to secure the
obligations of Knowledge Well's shareholders to indemnify CBT for any damages,
including reasonable attorneys' fees and expenses, resulting from any breach of
their representations and warranties under the Share Purchase Agreement. Subject
to certain conditions, the liability of the shareholders of Knowledge Well under
this indemnity, other than for damages caused by any breach of or inaccuracy in
any representations or warranties relating to taxes, will end two years from the
closing date. The liability of the shareholders of Knowledge Well under this
indemnity for damages caused by any breach of or inaccuracy in any
representations or warranties relating to taxes will end six years from the
closing date. In no event will any shareholder be liable under this indemnity or
any other theory of liability for damages in connection with the Share Exchange
for an amount greater than the lesser of (1) such shareholder's pro rata share
of the acquisition price or (2) such shareholder's pro rata share of the damages
suffered by CBT.

         CBT has agreed to use its reasonable best efforts to cause the CBT
Ordinary Shares to be registered under The Securities Act of 1933, as amended,
and has agreed to prepare and file with the Securities and Exchange Commission
(the "SEC") a registration statement covering all of such CBT Ordinary Shares
within 30 days after the closing to permit the resale of all of such CBT
Ordinary Shares. CBT has further agreed to maintain the effectiveness of the
registration statement for two years following the closing.

         Certain shareholders of Knowledge Well have agreed from the closing
until October 1, 1999 not to dispose of any CBT Ordinary Shares without the
prior written consent of the members of CBT's board of directors who are not
former shareholders of Knowledge Well. Additionally, these individuals have
agreed from October 1, 1999 to October 1, 2000 not to dispose of more than 50%
of these CBT Ordinary Shares without the prior written consent of the members of
CBT's board of directors who are not former shareholders of Knowledge Well.
<PAGE>

          William G. McCabe is a former Chief Executive Officer and the current
Chairman of CBT's board of directors and is also the founder and a former member
of the board of each of Knowledge Well Limited and Knowledge Well Group Limited.
Immediately prior to the closing of the Share Exchange, Mr. McCabe beneficially
owned approximately 69.0% (on a fully diluted basis) of Knowledge Well.

          Gregory M. Priest is CBT's former Vice President, Finance and Chief
Financial Officer and its current President and Chief Executive Officer and a
member of its board of directors. At the time the Share Purchase Agreement was
originally executed, Mr. Priest was the President and Chief Executive Officer
and a member of the board of each of Knowledge Well Limited and Knowledge Well
Group Limited. Immediately prior to the closing of the Share Exchange, Mr.
Priest beneficially owned approximately 9.7% of Knowledge Well (on a fully
diluted basis).

          John M. Grillos, CBT's current Chief Operating Officer and a member of
its board of directors, owned approximately 0.9% of Knowledge Well (on a fully
diluted basis). In addition, ITech Partners L.P., a venture capital limited
partnership of which Mr. Grillos serves as the sole general partner, owned
approximately 0.7% of Knowledge Well (on a fully diluted basis).

          The foregoing individuals did not participate in CBT's decision making
process with respect to approval of the Share Exchange.

Agreement, at the Share Exchange, CBT shall purchase from the Shareholders, and
the Shareholders, as beneficial owners, shall sell, assign, transfer and
deliver to CBT, the KnowledgeWell Shares free and clear of any pledge, lien,

Shareholders contained herein, and in consideration of the aforesaid sale,
assignment, transfer and delivery of the KnowledgeWell Shares, CBT shall pay to
each Shareholder, in full payment for each KnowledgeWell Share so sold,
assigned, transferred and delivered by such Shareholder and the agreements of
such Shareholder made in connection with the transactions contemplated hereby,

CBT Ordinary Shares or ADSs occurring after the date hereof and prior to the
Closing Date (as hereinafter defined).

   (d) No fraction of an Ordinary Share or ADS will be issued, but in lieu
thereof, each Shareholder who would otherwise be entitled to a fraction of an
Ordinary Share or ADS (after aggregating all fractional Ordinary Shares or ADSs
to be received by such Shareholder) shall be entitled to receive from CBT an
amount of cash (rounded to the nearest whole cent) equal to the product of (i)
such fraction, multiplied by (ii) the closing price of an ADS on November 27,
1998, as reported on the Nasdaq National Market.

   (a) Upon Closing, CBT shall make available to each Shareholder as payment of

Section 1.2(a) (the "Escrow Amount") to be deposited into an escrow account
pursuant to Section 8.3 below.

   (b) Notwithstanding Section 1.5(a), in the event that a Restricted ADR
Facility (the "Restricted ADR Facility") has been arranged with The Bank of New

shall make available to each Shareholder as payment of such Shareholder's part
of the Acquisition Price in accordance with this Article I Restricted American
Depositary Receipts ("ADRs") of CBT in the name of such Shareholder issued in
accordance with a Restricted Deposit Agreement among CBT, The Bank of New York,
as depository (the "Depository"), and all owners and beneficial owners of such
ADRs (the "Deposit Agreement"), which ADRs shall represent that number of ADSs
to be issued to that Shareholder as payment of such Shareholder's part of the
Acquisition Price in accordance with Section 1.2(a). Prior to or concurrent
with the Share Exchange, CBT shall deliver or cause to be delivered to the
Custodian (as defined in the Deposit Agreement), in accordance with the Deposit
Agreement, the Ordinary Shares represented by the ADSs to be issued in
connection with the Share Exchange, with instructions to the Depository to
create and deliver the ADRs representing the ADSs to each Shareholder as
provided above; provided, however, that CBT shall cause the ADRs representing
402,000 ADSs to be issued pursuant to Section 1.2(a) (the "Escrow Amount") to
be deposited into an escrow account pursuant to Section 8.3 below.

   (c) If any ADR or Ordinary Share, as the case may be, is to be issued in a
name other than that of the Shareholder entitled thereto pursuant to the Share
Exchange, it will be a condition of the issuance thereof that the person
requesting such exchange will have paid to CBT or any agent designated by it
any transfer or other taxes required by reason of the issuance of an ADR or
Ordinary Share in any name other than that of the registered holder of the
KnowledgeWell Certificate surrendered, or established to the satisfaction of
CBT or any agent designated by it that such tax has been paid or is not
payable.

   1.6 No Further Ownership Rights in KnowledgeWell Shares. All ADSs or
Ordinary Shares, as the case may be, issued in exchange for KnowledgeWell
Shares in accordance with the terms of this Agreement (including any cash paid
in respect of fractional shares) shall be deemed to have been issued in full
satisfaction of all rights pertaining to such KnowledgeWell Shares.

   1.7 Lost, Stolen or Destroyed KnowledgeWell Certificates. In the event any
KnowledgeWell Certificates evidencing KnowledgeWell Shares shall have been
lost, stolen or destroyed, then upon Closing, the holder thereof shall be

                                  ARTICLE III

         ADDITIONAL REPRESENTATIONS AND WARRANTIES OF THE SHAREHOLDERS

   Each Shareholder, severally and not jointly, represents and warrants to CBT
as of November 30, 1998 as follows:

   3.1 Authority. This Agreement and each agreement attached as an exhibit
hereto (collectively, the "Related Agreements") to which such Shareholder is a
party have been duly and validly executed and delivered by, or on behalf of,
Shareholder and, assuming due authorization, execution and delivery by the
other parties hereto and thereto, constitute valid and binding obligations of
Shareholder, enforceable against Shareholder in accordance with their
respective terms, subject to the laws of general application relating to
bankruptcy, insolvency and the relief of debtors and to rules of law governing
specific performance, injunctive relief or other equitable remedies.

   3.2 Conflicts. Neither the execution and delivery of each of this Agreement
and the Related Agreements to which such Shareholder is a party nor the
performance by Shareholder of his, her or its respective obligations hereunder
or thereunder, violate, conflict with, or constitute a default under any
agreement or commitment to which Shareholder is a party, or violate any statute
or law or any judgment, decree, order, regulation or rule of any court or other
Governmental Entity applicable to Shareholder that would preclude Shareholder
from entering into this Agreement or the Related Agreements to which such
Shareholder is a party or consummating the transactions contemplated hereby or
thereby.

<PAGE>

   3.3 Consents. No consent, waiver, approval, order or authorization of, or
declaration, filing or registration with, any Governmental Entity or any third
party is required to be made or obtained by Shareholder in connection with the
execution and delivery by Shareholder of each of this Agreement and the Related
Agreements to which such Shareholder is a party or the performance by
Shareholder of his, her or its obligations hereunder or thereunder or the
consummation by Shareholder of the transactions contemplated herein or therein.

   3.4 Title. Shareholder has the sole right to transfer the KnowledgeWell
Shares registered in his, her or its name to CBT. Upon delivery of
KnowledgeWell Certificates representing such KnowledgeWell Shares to CBT,
together with a duly executed transfer instrument, CBT will receive good title
to such KnowledgeWell Shares, free and clear of all Liens.

   3.5 Taxes. Shareholder has had an opportunity to review with his, her or its
respective tax advisors the tax consequences to Shareholder of the Share
Exchange and the transactions contemplated by this Agreement. Shareholder
understands that he, she or it must rely solely on his, her or its advisors and
not on any statements or representations by CBT, KnowledgeWell or any of their
respective agents. Shareholder understands that he, she or it (and not CBT or
KnowledgeWell) shall be responsible for his, her or its own tax liability that
may arise as a result of the Share Exchange or any other transactions
contemplated by this Agreement or the Related Agreements.

   3.6 Sufficient Assets. Shareholder will have sufficient assets, after sale
of the KnowledgeWell Shares owned by Shareholder as contemplated hereby, to
satisfy all of Shareholder's obligations to his, her or its creditors, as the
same become due and payable.

   3.7 Release of Liabilities. Shareholder has procured the release of
KnowledgeWell and the Subsidiary unconditionally from all liability whatsoever
(actual or contingent) to the Shareholder and/or to third parties in respect of
the liabilities and obligations of Shareholder, including, without prejudice to
the generality of the foregoing, all guarantees given by KnowledgeWell and/or
the Subsidiary to the bankers of the Shareholder.

   3.8 Investment Experience. Shareholder has substantial experience in
evaluating and investing in private placement transactions so that Shareholder
is capable of evaluating the merits and risks of receiving CBT's securities in
the Share Exchange. Shareholder, by reason of his, her or its business or
financial experience or the business or financial experience of its
professional advisors who are unaffiliated with and who are not compensated by
CBT or any affiliate of CBT, directly or indirectly, has the capacity to
protect its own interests in connection with the Share Exchange.

   3.9 Investment. Shareholder is acquiring CBT's shares for investment for
Shareholders' own account, not as a nominee or agent, and not with the view to,
or for resale in connection with, any distribution thereof. Shareholder
understands that the CBT shares to be received in the Share Exchange have not
been, and will not be, registered under the United States Securities Act of
1933, as amended (the "Securities Act") by reason of a specific exemption from
the registration provisions of the Securities Act which depends upon, among
other things, the bona fide nature of the investment intent and the accuracy of
Shareholder's representations as expressed herein. If Shareholder is not an
individual, Shareholder has not been formed for the specific purpose of
acquiring CBT's shares in the Share Exchange.

   3.10 Rule 144. Shareholder acknowledges that the CBT shares to be received
are characterized as "Restricted Securities" and must be held indefinitely
unless subsequently registered under the Securities Act or an exemption from
such registration is available. Shareholder is aware of the provisions of Rule
144 promulgated under the Securities Act, which permit limited resale of
securities purchased in a private placement subject to the satisfaction of
certain conditions, including (except as limited by Rule 144(k)), among other
things, the existence of a public market for the shares, the availability of
certain current public information about CBT, the resale occurring at least one
year after a party has purchased and paid for the security to be sold, the sale
being effected through a "broker's transaction" or in transactions directly
with a "market maker" (as provided by Rule 144(f)) and the number of shares
being sold during any three-month period not exceeding specified limitations.

<PAGE>

   3.11 Nature of Solicitation; Access to Data. Shareholder has had the
opportunity to ask questions of and receive answers from CBT or a person acting
on its behalf concerning the terms and conditions of this transaction as well
as to obtain any information requested by Shareholder. Shareholder has asked
such questions and received such answers as were necessary to enable him or it
to make an informed decision as to whether to participate in the Share
Exchange. Shareholders' decision to so participate is based in part on the
answers to such questions as Shareholder and its representatives have raised
concerning the transaction and on his or its own evaluation of the risks and
merits of CBT's business activities. Shareholder confirms that at no time was
Shareholder presented with or solicited by or through any leaflet, public
promotional meeting, television advertisement or any other form of general
advertising in connection and concurrently with such communicated offer.

   3.12 Accredited Shareholder. Shareholder is an "Accredited Investor" as that
term is defined in Rule 501 of Regulation D, promulgated by the United States
Securities and Exchange Commission under the Securities Act.

   3.13 Shelf Registration Statement Information. The information supplied by
Shareholder for inclusion in the registration statement contemplated by the
Rights Declaration does not contain, and will not contain at the effective date
of such registration statement, any untrue statement of a material fact or
omit, and will not omit at the effective date of such registration statement,
to state any material fact required to be stated therein or necessary in order
to make the statements therein not misleading.

   3.14 Representations Complete. None of the statements furnished by
Shareholder in or in connection with documents mailed or delivered to the
shareholders of CBT in connection with soliciting their approval of this
Agreement, contains or will contain at the Closing Date, the date of such
mailing or delivery or the date of the CBT vote, any untrue statement of a
material fact, or omits or will omit at the Closing Date, the date of such
mailing or delivery or the date of the CBT vote to state any material fact
necessary in order to make the statements contained herein or therein, in the
light of the circumstances under which they were made, not misleading.

into this Agreement and the Related Agreements to which CBT is a party and to
consummate the transactions contemplated hereby and thereby. The execution and
delivery of this Agreement and the Related Agreements to which CBT is a party
and the consummation of the transactions contemplated hereby and thereby have
been duly authorized by all necessary corporate action on the part of CBT and
no further action is required on the part of CBT to authorize the Share
Exchange, this Agreement, the Related Agreements to which CBT is a party and
the transactions contemplated hereby or thereby, except for approval by the
shareholders of CBT and as expressly set forth elsewhere herein. This Agreement
and each Related Agreement to which CBT is a party has been duly executed and
delivered by CBT and, assuming due authorization, execution and delivery by
other parties hereto, constitute the valid and binding obligations of CBT,
enforceable in accordance with their respective terms, except as such
enforceability may be limited by principles of public policy and subject to the
laws of general application relating to bankruptcy, insolvency and the relief
of debtors and rules of law governing specific performance, injunctive relief
or other equitable remedies.

<PAGE>

   4.3 No Conflict. The execution and delivery of this Agreement and the
Related Agreements to which CBT is a party do not, and the consummation of the
transactions contemplated hereby and thereby will not, conflict with, or result
in any violation of, or default under (with or without notice or lapse of time,

indenture, lease, contract or other agreement or instrument, permit,
concession, franchise, license, judgment, order, decree, statute, law,
ordinance, rule or regulation applicable to CBT or its properties or assets,
other than any such conflicts, violations, defaults, terminations,
cancellations or accelerations which would not have a material adverse effect
on the ability of CBT to consummate the transactions contemplated hereby and
thereby.

   4.4 Consents. No consent, approval, order or authorization of, or
registration, declaration or filing with, any Governmental Entity, or any third
party is required by or with respect to CBT in connection with the execution
and delivery of this Agreement and the Related Agreements to which CBT is a
party by CBT or the consummation by CBT of the transactions contemplated hereby
and thereby, except for (i) such consents, approvals, orders, authorizations,
registrations, declarations and filings as may be required under applicable
state and federal securities laws and the laws of any foreign country, and (ii)
such other consents, authorizations, filings, approvals and registrations which
if not obtained or made would not have a material adverse effect on the ability
of CBT to consummate the transactions contemplated hereby and thereby.

   (a) The authorized share capital of CBT is IR(Pounds)11,250,000 divided into
120,000,000 Ordinary Shares, par value IR(Pounds)9.375 pence per share, of
which 44,355,890 shares were issued and outstanding as of October 31, 1998. No
shares of preferred stock are issued or outstanding. All such shares of CBT
have been duly authorized and validly issued, and all such issued and
outstanding shares are fully paid and nonassessable. An aggregate of 4,049,007
Ordinary Shares are subject to outstanding, unexercised options issued to
employees, directors and consultants pursuant to CBT employee benefit plans,
and 3,640,537 shares remain available for future grant. There are no other
options, warrants, calls, rights, commitments or agreements of any character to
which CBT is a party or by which it is bound obligating CBT to issue, deliver,
sell, repurchase or redeem, or cause to be issued, delivered, sold, repurchased
or redeemed, any shares of the capital stock of CBT or obligating CBT to grant,
extend or enter into any such option, warrant, call, right, commitment or
agreement.

   (b) The CBT Ordinary Shares to be issued pursuant to the Share Exchange will
be, at the Share Exchange, duly authorized, validly issued, fully paid, not
subject to any call, preemptive or similar rights and nonassessable. Upon
issuance of the Ordinary Shares issued pursuant to Article I, the right, title
and interest to such Ordinary Shares will be transferred to the Shareholders,
free and clear of all liens, charges, encumbrances, security interests and
claims.

   (c) CBT meets all requirements for the qualification of the inclusion and
quotation of ADSs on the Nasdaq National Market System ("NMS"). ADSs to be
issued pursuant to the Share Exchange or in connection with the resale of
Ordinary Shares issued in the Share Exchange, as the case may be, will be
included and quoted in the NMS.

   4.6 SEC Documents; CBT Financial Statements. CBT has made available to each
Shareholder true and complete copies of CBT's annual report on Form 10-K for
the fiscal year ended December 31, 1997 and quarterly reports on Form 10-Q for
each of the three fiscal quarters in the period ended September 30, 1998, which
CBT filed under the United States Securities Exchange Act of 1934, as amended
(the "Exchange Act"), with the Securities and Exchange Commission (the "SEC")
and of its registration statement on Form S-4 (Registration Statement No. 333-
51159), which CBT filed under the Securities Act with the SEC (collectively,
the "SEC Documents"). As of their respective dates, the SEC Documents complied
in all material respects with the requirements of the Exchange Act and the
Securities Act, as applicable, and the SEC Documents did not contain any untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements made therein, in light of
the circumstances in which they were made, not

included in the SEC Documents (the "CBT Financial Statements") comply as to
form in all material respects with applicable accounting requirements and with
the published rules and regulations of the SEC with respect thereto, have been
prepared in accordance with generally accepted accounting principles in the
United States consistently applied and fairly present in all material respects
the consolidated financial position of CBT at the dates thereof and of its
operations and cash flows for the periods then ended. Except as set forth in
Schedule 4.6, since September 30, 1998, there have not been any changes in the
assets, liabilities, financial condition, business or operations of CBT from
that reflected in the SEC Documents except changes which have not been, either
individually or in the aggregate, materially adverse to CBT. Except as set
forth in Schedule 4.6, since September 30, 1998, there has not been, occurred
or arisen any event or condition which has had a material adverse effect on the
business, assets (including intangible assets), financial conditions or results
of operations of CBT and subsidiaries, taken as a whole. Since September 30,
1998, CBT has filed all forms, reports and documents with the SEC required to
be filed by it pursuant to the U.S. federal securities laws and the rules and
regulations of the SEC (collectively, "Securities Laws"), each of which
complied as to form, at the time such form, document or report was filed, in
all material respects with the applicable requirements of all Securities Laws,
except for such failures to file or to comply with Securities Laws as are not,
individually or in the aggregate, materially adverse to CBT and its
subsidiaries, taken as a whole. None of the statements made by CBT in or in
connection with documents mailed or delivered to the shareholders of CBT in
connection with soliciting their approval of this Agreement contains or will
contain at the Closing Date or the date of the CBT shareholder vote, any untrue
statement of a material fact, or omits or will omit at the Closing Date or the
date of the CBT shareholder vote to state any material fact necessary in order
to make the statements contained herein or therein, in the light of the
circumstances under which they were made, not misleading.

identifying all persons who are "affiliates" (as that term is used in
paragraphs (c) and (d) of Rule 145 under the Securities Act) of KnowledgeWell
(collectively, the "KnowledgeWell Affiliates").

   (b) Prior to the Exchange Date, KnowledgeWell shall cause each KnowledgeWell
Affiliate to execute and deliver a written agreement in the form attached as
Exhibit C (the "Affiliate Agreement"), that he will not sell, offer to sell, or
otherwise dispose of any of the Ordinary Shares or ADSs, as the case may be,
issued to him pursuant to the Share Exchange, except in compliance with Rule
145 or another exemption for the registration requirements of the Securities
Act. CBT shall be entitled to place appropriate legends on the certificates
evidencing any Ordinary Shares or ADSs, as the case may be, or other CBT
securities to be received by KnowledgeWell Affiliates, and to issue appropriate
stop transfer instructions to the transfer agent for CBT Ordinary Shares and,
if applicable, the Depositary consistent with the terms of such Affiliate
Agreement.

   6.10 Additional Documents and Further Assurances. Each party hereto, at the
request of the other party hereto, shall execute and deliver such other
instruments and do and perform such other acts and things as may be reasonably
necessary or desirable for effecting completely the consummation of this

and agrees that on or prior to the Closing Date he will acquire all of the "C"
Ordinary Shares of IR25p each in the capital of KW Limited in issue from the
holder thereof. Mr. McCabe hereby further covenants and agrees that following
such acquisition, and in any event not later than the Closing Date, he will
exercise the options held by him pursuant to the Option Agreements dated August
31, 1998 in respect of shares in each of KW Limited and KW Group and that in
the event of his failing to exercise such options as aforesaid, such options
shall forthwith lapse and shall be of no further force and effect. Any shares
issued to Mr. McCabe pursuant to the exercise of the foregoing options shall be
deemed to be "KnowledgeWell Shares" for purposes of this Agreement.

   6.14 Tax-Free Reorganization. The parties hereto shall not take any action
either prior to or after the Closing that could reasonably be expected to cause
the Share Exchange to fail to qualify as a "reorganization" under Section
368(a) of the Code.

   6.15 Resale Registration Statement. CBT shall file, within thirty (30) days
following the Closing Date, a registration statement on Form S-3 with the SEC
covering the resale of the Ordinary Shares and the ADSs representing such
Ordinary Shares received by the Shareholders hereunder. CBT shall use its
reasonable best efforts to cause such registration statement to be declared
effective under the Securities Act as promptly as

<PAGE>

reasonably practicable. Any such registration shall be subject to the terms and
conditions set forth in the Rights Declaration. CBT covenants that with respect
to information contained in the registration statement and supplied by CBT in
connection therewith, such information will not contain any untrue statement of
a material fact or omit to state any material fact required to be stated
therein or necessary in order to make the statements therein not misleading, or
omit to state a material fact necessary to make the statements therein, in
light of the circumstances under which they were made, not misleading. Each
Shareholder covenants that with respect to information contained in the
registration statement and supplied in writing by such Shareholder in
connection therewith, such information will not contain any untrue statement of
a material fact or omit to state any material fact required to be stated
therein or necessary in order to make the statements therein not misleading, or
omit to state a material fact necessary to make the statements therein, in
light of the circumstances under which they were made, not misleading.

   6.16 Restricted ADR Facility. CBT shall use its reasonable best efforts to
arrange a Restricted ADR Facility at the Bank of New York with respect to the
Ordinary Shares to be issued to the Shareholders hereunder, such that at the
Closing the Shareholders will receive Restricted ADSs (each representing one
restricted Ordinary Share) in lieu of restricted Ordinary Shares.

                                  ARTICLE VIII

         SURVIVAL OF REPRESENTATIONS AND WARRANTIES; ESCROW; INDEMNITY

   8.1 Survival of Representations, Warranties and Covenants. All
representations and warranties in this Agreement or in any instrument delivered
pursuant to this Agreement and all covenants to be performed prior to the
Closing Date shall not in any respect be extinguished or affected by the
Closing shall survive the Share Exchange for a period ending at 5:00 p.m.,
California time, on the date two (2) years from the Closing Date, provided that
representations and warranties related to Tax shall survive the Share Exchange
for a period ending at 5:00 p.m., California time, on the date six (6) years
from the Closing Date.

   8.2 Agreement to Indemnify.

   (a) Each Shareholder agrees, jointly and severally, to indemnify and hold
CBT and its affiliates, officers, directors, employees and shareholders
(collectively, the "CBT Indemnitees") harmless against any losses, claims,
damages, costs, expenses or other liabilities (including reasonable attorneys'
fees and expenses) (collectively, "Damages") resulting from (i) any breach of
or inaccuracy in any representations and warranties of the Shareholders set
forth in Article II of this Agreement or in any certificate delivered by the
Shareholders or KnowledgeWell pursuant to this Agreement, or (ii) any breach or
default by KnowledgeWell or the Shareholders of any covenant, obligation or
other agreement of KnowledgeWell or the Shareholders set forth in this
Agreement (each, a "CBT Indemnifiable Claim," which term shall include a claim
made pursuant to the following sentence). In addition, each Shareholder agrees,
severally and not jointly, to indemnify and hold the CBT Indemnitees harmless
against any Damages resulting from any breach of or inaccuracy in any
representations and warranties of such Shareholder set forth in Article III of
this Agreement.

   (b) Subject to Section 8.4, the liability of the Shareholders under this
indemnity (other than in respect of Damages resulting from any breach of or
inaccuracy in any representations or warranties of the Shareholders relating to
Tax) shall expire at 5:00 p.m., California time, on the second anniversary of
the Closing Date (the "Two-Year Indemnity Termination Date"), and the liability
of the Shareholders under this indemnity in respect of Damages resulting from
any breach of or inaccuracy in any representations or warranties of the
Shareholders relating to Tax shall expire at 5:00 p.m., California time, on the
sixth anniversary of the Closing Date (the "Six-Year Indemnity Termination
Date" and, collectively with the Two-Year Indemnity Termination Date, the
"Indemnity Termination Dates").

   8.3 Escrow Arrangements; Limits of Liability.

   (a) In no event shall (i) any Shareholder be liable to CBT, any other CBT
Indemnitees or anyone claiming through either of them under this Article VIII
or any other theory of liability for Damages or other amounts in connection
with the transactions contemplated by this Agreement or any of the Related
Agreements in excess of the lesser of (A) such Shareholder's pro rata share
(assuming exercise of all of such Shareholder's Knowledge Well Options assumed
by CBT regardless of whether such options are vested or unvested) of the

<PAGE>

Acquisition Price and (B) such Shareholder's pro rata share (assuming exercise
of all of such Shareholder's Knowledge Well Options assumed by CBT regardless
of whether such options are vested or unvested) of the aggregate amount of such
Damages or other amounts or (ii) any CBT Indemnitee be reimbursed for any
Damages under this Article VIII or any other theory of liability in connection
with the transactions contemplated by this Agreement or any of the Related
Agreements until the aggregate of all Damages exceeds US$500,000 (after which
the all Damages, including such US$500,000, shall become payable in accordance
with the provisions of this Article VIII). As partial security for the
obligations of each Shareholder pursuant to this Article VIII, the Escrow
Amount shall be deposited with an escrow agent and shall be controlled pursuant
to the terms of the escrow agreement (the "Escrow Agreement") in substantially
the form attached hereto as Exhibit E.

   (b) For purposes of determining the amount of any Damages incurred by the
CBT Indemnitees, the amount of any Damages shall be reduced to the extent of
(i) any net tax benefit actually realized by the CBT Indemnitees arising from
the incurrence or payment by the CBT Indemnitees of the indemnifiable loss to
which such Damages relate and after giving full effect to the actual tax effect
of receipt of the indemnification payments to the CBT Indemnitees, if any, and
(ii) any amounts previously received by the CBT Indemnitees pursuant to this
Article VIII for losses resulting from the same facts or events.

   (c) Nothing in this Agreement shall in any way diminish any obligation on
the part of CBT under applicable law to attempt to mitigate its loss. If the
amount of any Damages, at any time subsequent to the making of a payment
hereunder in respect thereof, is reduced (i) by recovery, settlement or
otherwise under or pursuant to any insurance coverage or (ii) pursuant to any
claim, recovery, settlement or otherwise against or with any person or entity
that is not an affiliate of a CBT Indemnitee, the amount of such reduction, in
each case less any costs or expenses of recovery (including attorney's fees and
expenses), will be repaid by the CBT Indemnitees to (A) the Escrow Agent to be
controlled pursuant to the terms of the Escrow Agreement if such repayment is
made prior to the Two-Year Indemnity Termination Date or (B) the Shareholders
if such repayment is made after the Two-Year Indemnity Termination Date.

   (d) CBT confirms to the Shareholders that, as of November 30, 1998, it had
not formulated nor is it in the process of formulating any claim under this
Agreement. The information supplied by Knowledge Well or its professional
advisers to the Shareholders or their agents, representatives or advisors in
connection with the representations and warranties and indemnities in this
Agreement and the contents of the Knowledge Well Disclosure Letter or otherwise
in relation to the business or affairs of Knowledge Well shall not be deemed a
representation, warranty or guarantee of its accuracy by Knowledge Well to the
Shareholders, and the Shareholders hereby irrevocably waive any claim against
Knowledge Well (and its employees and agents) which any of them might otherwise
have in respect of it.

   8.4 Survival of Indemnity; Indemnification Procedures; Time Limits.

   (a) The indemnification obligations of each Shareholder pursuant to Section
8.2 for amounts up to the Escrow Amount shall apply only to those claims for
indemnification as to which CBT has given written notice thereof pursuant to
the terms of the Escrow Agreement on or prior to the relevant Indemnity
Termination Date; provided that the foregoing shall not limit the liability of
such Shareholder for Damages incurred by CBT Indemnitees after the relevant
Indemnity Termination Date that result from a CBT Indemnifiable Claim if CBT
Indemnitees have given written notice of such CBT Indemnifiable Claim prior to
the relevant Indemnity Termination Date. CBT and each Shareholder agree that
the indemnification procedures set forth in the Escrow Agreement shall apply to
all claims for Damages up to the Escrow Amount resulting from a CBT
Indemnifiable Claim. Notwithstanding the foregoing, any claim for Damages in
respect of any breach of or inaccuracy in any representation or warranties of
the Shareholders relating to Tax made after the Two-Year Indemnity Termination
Date shall be administered in accordance with paragraph (c) of this Section 8.4
regardless of whether the amount is less than or exceeds the Escrow Amount.

   (b) The indemnification obligations of each Shareholder pursuant to Section
8.2 for amounts in excess of the Escrow Amount shall apply only to those claims
for indemnification as to which CBT has given written

<PAGE>

notice thereof pursuant to the terms of paragraph (c) of this Section 8.4 on or
prior to the relevant Indemnity Termination Date; provided that the foregoing
shall not limit the liability of such Shareholder for Damages incurred by CBT
Indemnitees after the relevant Indemnity Termination Date that result from a
CBT Indemnifiable Claim if CBT Indemnitees have given written notice of such
CBT Indemnifiable Claim prior to the relevant Indemnity Termination Date. CBT
and each Shareholder agree that the indemnification procedures set forth in
paragraph (c) of this Section 8.4 shall apply to all claims for Damages in
excess of the Escrow Amount resulting from a CBT Indemnifiable Claim.

   (c) If any CBT Indemnitee shall incur Damages that exceed the Escrow Amount,
there shall be delivered to each Shareholder a certificate signed in good faith
on behalf of CBT by an officer of CBT or by a member of the Special Committee
(an "Officer's Certificate") stating that a CBT Indemnitee has paid, properly
accrued, or reasonably anticipates that it will have to pay or accrue Damages
in an amount specified in such Officer's Certificate, with the basis for such
claim set forth in reasonable detail. Each Officer's Certificate shall be
delivered to each Shareholder in the manner specified in Section 10.1 hereof.
In the event CBT becomes aware of a third-party claim which CBT believes may
result in a demand which exceeds the Escrow Amount, CBT shall, as soon as
reasonably practicable, notify each Shareholder of such claim, and each
Shareholder shall be entitled, at their individual expense, to participate in
any defense of such claim. Delay in providing such notice shall not eliminate
such claim except to the extent that the Shareholders are prejudiced thereby.
CBT shall have the right in its sole discretion to settle any such claim;
provided, however, that except with the consent of a given Shareholder, no
settlement of any such claim with third-party claimants shall be determinative
of the validity and quantum of any claim against such Shareholder. In the event
that a given Shareholder has consented to any such settlement, such Shareholder
shall have no power or authority to object to the amount of any claim by CBT
against such Shareholder with respect to such settlement.

   8.5 Representative; Power of Attorney.

   (a) Each Shareholder hereby appoints Gethin Taylor of Peregrine Company
Managers Limited as agent and attorney-in-fact (the "Representative") for such
Shareholder to give and receive notices and communications, to authorize
delivery to CBT of ADSs or Ordinary Shares, as the case may be, from the Escrow
Amount in satisfaction of claims by CBT, to object to such deliveries, to agree
to, negotiate, enter into settlements and compromises of, such claims, to
perform such other obligations and make such other decisions as are set forth
in the Escrow Agreement, and to take all actions necessary or appropriate in
the judgment of the Representative for the accomplishment of the foregoing.
Such agency may be changed by the Shareholders from time to time upon not less
than thirty (30) days prior written notice to CBT; provided that the
Representative may not be removed unless holders of a two-thirds interest of
the Escrow Amount agree to such removal and to the identity of the substituted
agent. The Representative may resign upon not less than thirty (30) days prior
written notice to CBT and to all holders of an interest in the Escrow Amount.
Any vacancy in the position of the Representative may be filled by approval of
the holders of a majority in interest of the Escrow Amount. No bond shall be
required of the Representative, and the Representative shall not receive
compensation for his or her services. Notices or communications to or from the
Representative shall constitute notice to or from each of the Shareholders.

   (b) The Representative shall not be liable for any act done or omitted
hereunder as Representative while acting in good faith and without
recklessness. The Shareholders shall severally indemnify the Representative and
hold the Representative harmless against any loss, liability or expense
incurred without recklessness or bad faith on the part of the Representative
and arising out of or in connection with the acceptance or administration of
the Representative's duties hereunder, including the reasonable fees and
expenses of any legal counsel retained by the Representative.

   (c) A decision, act, consent or instruction of the Representative shall be
final, binding and conclusive upon each of such Shareholders, and the Escrow
Agent and CBT may rely upon any such decision, act, consent or instruction of
the Representative as being the decision, act, consent or instruction of each
Shareholder. The Escrow Agent and CBT are hereby relieved from any liability to
any person for any acts done by them in accordance with such decision, act,
consent or instruction of the Representative.

   9.1 Termination. Except as provided in Section 9.2 below, this Agreement may
be terminated and the Share Exchange abandoned at any time prior to the Closing
Date:

     (a) by mutual consent of the Shareholders or their attorneys and CBT;

     (b) by CBT or by William G. McCabe and/or Gregory M. Priest, as the
  representatives on behalf of the Shareholders, if: (i) the Closing Date has
  not occurred by June 30, 1999 (provided that the right to terminate this
  Agreement under this clause 9.1(b)(i) shall not be available to any party
  whose willful failure to fulfill any obligation hereunder has been the
  cause of, or resulted in, the failure of the Closing Date to occur on or
  before such date); (ii) there shall be a final nonappealable order of a
  federal or state court in the United States or a court in Ireland in effect
  preventing consummation of the Share Exchange; or (iii) there shall be any
  statute, rule, regulation or order enacted, promulgated or issued or deemed
  applicable to the Share Exchange by any Governmental Entity that would make
  consummation of the Share Exchange illegal;

     (c) by CBT if there shall be any action taken, or any statute, rule,
  regulation or order enacted, promulgated or issued or deemed applicable to
  the Share Exchange, by any Governmental Entity, which would: (i) prohibit
  CBT's or KnowledgeWell's ownership or operation of any material portion of
  the business of KnowledgeWell or (ii) compel CBT or KnowledgeWell to
  dispose of or hold separate, as a result of the Share Exchange, any
  material portion of the business or assets of KnowledgeWell or CBT;

     (d) by CBT if it is not in material breach of its obligations under this
  Agreement and there has been a breach of any representation, warranty,
  covenant or agreement contained in this Agreement on the part of
  KnowledgeWell or any Shareholder and as a result of such breach the
  conditions set forth in Section 7.3(a) or 7.3(b), as the case may be, would
  not then be satisfied; provided, however, that if such breach is curable by
  KnowledgeWell or such Shareholder within thirty (30) days through the
  exercise of its reasonable best efforts, then for so long as KnowledgeWell
  or such Shareholder continues to exercise such reasonable best efforts CBT
  may not terminate this Agreement under this Section 9.1(d) unless such
  breach is not cured within thirty (30) days (but no cure period shall be
  required for a breach which by its nature cannot be cured);

     (e) by William G. McCabe and/or Gregory M. Priest, as the
  representatives on behalf of the Shareholders, if KnowledgeWell and the
  Shareholders are not in material breach of their respective obligations
  under this Agreement and there has been a breach of any representation,
  warranty, covenant or agreement contained in this Agreement on the part of
  CBT and as a result of such breach the conditions set forth in Section
  7.2(a) or 7.2(b), as the case may be, would not then be satisfied;
  provided, however, that if such breach is curable by CBT within thirty (30)
  days through the exercise of its reasonable best efforts, then for so long
  as CBT continues to exercise such reasonable best efforts Messrs. McCabe
  and/or Priest, as the representatives on behalf of the Shareholders, may
  not terminate this Agreement under this Section 9.1(e) unless such breach
  is not cured within thirty (30) days (but no cure period shall be required
  for a breach which by its nature cannot be cured).

   Where action is taken to terminate this Agreement pursuant to this Section
9.1, it shall be sufficient for such action to be authorized by the Independent
Committee of the Board of Directors of CBT on behalf of CBT or by William G.
McCabe and/or Gregory M. Priest, as the representatives on behalf of the
Shareholders, as the case may be.

   9.2 Effect of Termination. In the event of termination of this Agreement as
provided in Section 9.1, this Agreement shall forthwith become void and there
shall be no liability or obligation on the part of CBT, KnowledgeWell or the
Shareholders, or their respective officers, directors or shareholders, provided
that each party shall remain liable for any breaches of this Agreement prior to
its termination; and provided further that the provisions of Sections 6.3 and
Article X of this Agreement shall remain in full force and effect and survive
any termination of this Agreement.

<PAGE>

shareholders of CBT approve this Agreement, this Agreement may be amended by
the parties hereto at any time by execution of an instrument in writing signed
on behalf of each of the parties hereto.

   9.4 Extension; Waiver. At any time prior to the Closing Date, CBT, on the
one hand, and KnowledgeWell and William G. McCabe and/or Gregory M. Priest, as
the representatives on behalf of the Shareholders, on the other, may, to the
extent legally allowed, (i) extend the time for the performance of any of the
obligations of the other party hereto, (ii) waive any inaccuracies in the
representations and warranties made to such party contained herein or in any
document delivered pursuant hereto, and (iii) waive compliance with any of the
agreements or conditions for the benefit of such party contained herein. Any
agreement on the part of a party hereto to any such extension or waiver shall
be valid only if set forth in an instrument in writing signed on behalf of CBT
by a member of the Independent Committee of the Board of Directors, on behalf
of KnowledgeWell by an officer or director of KW Limited or KW Group, and on
behalf of the Shareholders by William G. McCabe and/or Gregory M. Priest, as

   (d) if to a Shareholder, at such Shareholder's address as is specified on
Exhibit A to this Agreement.

   10.2 Interpretation. The words "include," "includes" and "including" when
used herein shall be deemed in each case to be followed by the words "without
limitation." The word "agreement" when used herein shall be deemed in each case
to mean any contract, commitment or other agreement, whether oral or written,
that is legally binding. As used in this Agreement, the phrase "to the best of
[a party's] knowledge," "to [a party's] knowledge," "[a party] is not aware,"
and similar phrases shall mean the actual knowledge of such party, or of the
officers and directors of such party, after careful consideration of the
matters set forth in the representation that is so qualified and after
performing or causing to be performed a reasonably diligent review of all
files, documents, agreements and other materials in such person's possession or
subject to his or her control. The table of contents and headings contained in
this Agreement are for reference purposes only and shall not affect in any way
the meaning or interpretation of this Agreement.

   10.3 Counterparts. This Agreement may be executed in one or more
counterparts, all of which shall be considered one and the same agreement and
shall become effective when one or more counterparts have been signed by each
of the parties and delivered to the other party, it being understood that all
parties need not sign the same counterpart.

   10.4 Entire Agreement; Successors; Assignment. This Agreement, the schedules
and Exhibits hereto, and the documents and instruments and other agreements
among the parties hereto referenced herein: (a) constitute the entire agreement
among the parties with respect to the subject matter hereof and supersede all
prior agreements and understandings, both written and oral, among the parties
with respect to the subject matter hereof; (b) are not intended to confer upon
any other person any rights or remedies hereunder; and (c) shall not be
assigned by operation of law or otherwise except as otherwise specifically
provided. Notwithstanding the foregoing, this Agreement shall be binding upon
and enforceable against administrators, executors, representatives, heirs,
legatees and devisees of the Shareholders.

   10.5 Severability. In the event that any provision of this Agreement or the
application thereof, becomes or is declared by a court of competent
jurisdiction to be illegal, void or unenforceable, the remainder of this
Agreement will continue in full force and effect and the application of such
provision to other persons or circumstances will be interpreted so as
reasonably to effect the intent of the parties hereto. The parties further
agree to replace such void or unenforceable provision of this Agreement with a
valid and enforceable provision that will achieve, to the extent possible, the
economic, business and other purposes of such void or unenforceable provision.

   10.6 Other Remedies. Except as otherwise provided herein, any and all
remedies herein expressly conferred upon a party will be deemed cumulative with
and not exclusive of any other remedy conferred hereby, or by law or equity
upon such party, and the exercise by a party of any one remedy will not
preclude the exercise of any other remedy. Notwithstanding any provision of
this Agreement to the contrary, the parties expressly agree that reasonable
attorney's fees may be recoverable in connection with any action to enforce
contractual rights under Section 6.15 of this Agreement.

   10.7 Governing Law; Jurisdiction. This Agreement shall be governed by and
construed in accordance with the laws of the State of California, regardless of
the laws that might otherwise govern under applicable

<PAGE>

principles of conflicts of laws thereof. Each of the parties hereto hereby
consents to the jurisdiction and venue of any state or U.S. federal court in
California with respect to matters arising out of or related to this Agreement,
agrees that process may be served upon them in any manner authorized by the
laws of the State of California for such persons and waives and covenants not
to assert or plead any objection which they might otherwise have to such
jurisdiction and such process.

   10.8 Rules of Construction. The parties hereto agree that they have been
represented by counsel during the negotiation and execution of this Agreement
and, therefore, waive the application of any law, regulation, holding or rule
of construction providing that ambiguities in an agreement or other document
will be construed against the party drafting such agreement or document.

   10.9 Specific Performance. The parties hereto agree that irreparable damage
would occur in the event that any of the provisions of this Agreement were not
performed in accordance with their specific terms or were otherwise breached.
It is accordingly agreed that the parties shall be entitled to an injunction or
injunctions to prevent breaches of this Agreement and to enforce specifically
the terms and provisions hereof in any court of the United States or any state
having jurisdiction, this being in addition to any other remedy to which they
are entitled at law or in equity.

   10.10 Share Legends. All certificates representing any of the CBT Ordinary
Shares or ADRs to be issued pursuant to this Agreement shall have endorsed
thereon a restrictive legend substantially as follows:

     (a) "THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT
  OF 1933, AS AMENDED, OR UNDER ANY STATE SECURITIES LAWS. THEY MAY NOT BE
  SOLD, OFFERED FOR SALE, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN

  OPINION OF COUNSEL SATISFACTORY TO THE CORPORATION THAT SUCH REGISTRATION
  IS NOT REQUIRED."

     (b) Any legend required to be placed thereon by applicable blue sky laws
  of any state or under the laws of Ireland.

   10.11 California Corporate Securities Law. THE SALE OF THE SECURITIES WHICH

                                    ANNEX B

            AMENDED AND RESTATED DECLARATION OF REGISTRATION RIGHTS

<PAGE>

           EXHIBIT B TO AMENDED AND RESTATED SHARE PURCHASE AGREEMENT

            AMENDED AND RESTATED DECLARATION OF REGISTRATION RIGHTS

   This Amended and Restated Declaration of Registration Rights ("Declaration")
is made as of March 30, 1999 by CBT Group PLC, a public limited company
organized under the laws of Ireland ("CBT" or the "Company") in connection with
an Amended and Restated Share Purchase Agreement (the "Share Purchase
Agreement") of even date herewith among the Company, Knowledge Well Group
Limited and Knowledge Well Limited, two private companies formed under the laws
of Ireland (collectively "KnowledgeWell"), and the shareholders of
KnowledgeWell ("Shareholders"). The Share Purchase Agreement provides for the
acquisition of all of the ordinary shares in the capital of KnowledgeWell by
the Company (the transaction hereinafter referred to as the "Share Exchange").
This Declaration amends and restates that certain declaration made as of
November 30, 1998 (the "Prior Declaration") by CBT. All rights and obligations
under the Prior Declaration are terminated in their entirety and superseded and
governed by this Declaration.

   1. Definitions. As used in this Declaration:

     (a) "CBT ADSs" means American Depositary Shares of CBT, each
  representing one CBT Ordinary Share.

     (b) "Exchange Act" means the United States Securities Exchange Act of
  1934, as amended.

     (c) "Form S-3" means such form under the Securities Act as in effect on
  the date hereof or any registration form under the Securities Act
  subsequently adopted by the SEC which similarly permits inclusion or
  incorporation of substantial information by reference to other documents
  filed by the Company with the SEC.

     (d) "Registrable Securities" means the CBT Ordinary Shares (or
  restricted CBT ADSs) issued to Shareholders pursuant to the Share Purchase
  Agreement, including all CBT ADSs into which such CBT Ordinary Shares may
  be converted, together with all other CBT Ordinary Shares issued in respect
  thereof (by way of stock split, dividend or otherwise).

     (e) "SEC" means the United States Securities and Exchange Commission.

     (f) "Securities Act" means the United States Securities Act of 1933, as
  amended.

   Capitalized terms not otherwise defined herein have the meanings given to
them in the Share Purchase Agreement.

   2. Registration. CBT shall use its reasonable best efforts to cause the
Registrable Securities issued pursuant to the transactions contemplated by the
Share Purchase Agreement to be registered under the Securities Act so as to
permit the resale thereof, and in connection therewith shall prepare and file
with the SEC within thirty (30) days following the closing of the Share
Exchange and shall use its reasonable best efforts to cause to become effective
a registration statement on Form S-3 or on such other form as is then available
under the Securities Act covering the Registrable Securities; provided,
however, that Shareholders shall provide CBT with all such information as may
be necessary under the Securities Act with respect to ownership of the
Registrable Securities for use in connection with any such registration
statement or prospectus. Such provision of information is a condition precedent
to the obligations of CBT pursuant to this Declaration. CBT shall not be
required to effect more than one (1) registration under this Declaration. The
offering made pursuant to such registration shall not be underwritten.

   3. Postponement of Registration. Notwithstanding Section 2 above, CBT shall
be entitled to postpone filing the registration statement pursuant to Section 2
for a reasonable period of time, but not in excess of forty-five (45) calendar
days after the applicable deadline, if the board of directors of CBT, acting in
good faith, determines that there exists material nonpublic information about
CBT which the board of directors does not wish to disclose in a registration
statement but which information would otherwise be required by the Securities
Act to be disclosed in the registration statement.

<PAGE>

   4. Obligations of CBT.

     (a) Subject to the limitations of Sections 2 and 3 above and Section 10
  below, CBT shall (i) prepare and file with the SEC the registration
  statement in accordance with Section 2 hereof with respect to the
  Registrable Securities and shall use its reasonable best efforts to cause
  such registration statement to become effective as promptly as practicable
  after filing and to keep such registration statement effective until the
  second anniversary of the closing of the Share Exchange; (ii) prepare and
  file with the SEC such amendments and supplements to such registration
  statement and the prospectus used in connection therewith as may be
  necessary, and to comply with the provisions of the Securities Act with
  respect to the sale or other disposition of all securities proposed to be
  registered in such registration statement until the second anniversary of
  the closing of the Share Exchange; (iii) furnish to Shareholders such
  number of copies of any prospectus (including any preliminary prospectus
  and any amended or supplemented prospectus) in conformity with the
  requirements of the Securities Act, and such other documents, as
  Shareholders may reasonably request in order to effect the offering and
  sale of the shares of the Registrable Securities to be offered and sold,
  but only while CBT shall be required under the provisions hereof to cause
  the registration statement to remain current; and (iv) use its reasonable
  best efforts to register or qualify the shares of the Registrable
  Securities covered by such registration statement under the securities or
  blue sky laws of such jurisdictions as Shareholders shall reasonably
  request (provided that CBT shall not be required in connection therewith or
  as a condition thereto to qualify to do business or to file a general
  consent to service of process in any such jurisdiction where it has not
  been qualified).

     (b) CBT shall notify Shareholders (i) when a prospectus or any
  prospectus supplement or post-effective amendment has been filed, and, with
  respect to the registration statement or any post-effective amendment, when
  the same has become effective; (ii) of any request by the SEC or any other
  federal or state governmental authority during the period of effectiveness
  of the registration statement for amendments or supplements to the
  registration statement or related prospectus or for additional information
  relating to the registration statement; (iii) of the issuance by the SEC or
  any other federal or state governmental authority of any stop order
  suspending the effectiveness of the registration statement or the
  initiation of any proceedings for that purpose; (iv) of the receipt by CBT
  of any notification with respect to the suspension of the qualification or
  exemption from qualification of any of the Registrable Securities for sale
  in any jurisdiction or the initiation or threatening of any proceeding for
  such purpose; or (v) of the happening of any event which makes any
  statement made in the registration statement or related prospectus or any
  document incorporated or deemed to be incorporated therein by reference
  untrue in any material respect or which requires the making of any changes
  in the registration statement or prospectus so that, in the case of the
  registration statement, it will not contain any untrue statement of a
  material fact or omit to state any material fact required to be stated
  therein or necessary to make the statements therein not misleading, and
  that in the case of the prospectus, it will not contain any untrue
  statement of a material fact or omit to state any material fact necessary
  to make the statements therein, in the light of the circumstances under
  which they were made, not misleading. CBT may, upon the happening of any
  event (A) of the kind described in clauses (ii), (iii), (iv), or (v) hereof
  or, (B) that, in the judgment of CBT's board of directors, renders it
  advisable to suspend use of the prospectus for no more than ninety (90)
  days in the aggregate in any twelve (12) month period of time due to
  pending corporate developments, public filings with the SEC or similar
  events, suspend use of the prospectus on written notice to Shareholders, in
  which case Shareholders shall discontinue disposition of Registrable
  Securities covered by the registration statement or prospectus until copies
  of a supplemented or amended prospectus are distributed to Shareholders or
  until Shareholders are advised in writing by CBT that the use of the
  applicable prospectus may be resumed. CBT shall use its reasonable best
  efforts to ensure that the use of the prospectus may be resumed as soon as
  practicable. CBT shall use its reasonable best efforts to obtain the
  withdrawal of any order suspending the effectiveness of the registration
  statement, or the lifting of any suspension of the qualification (or
  exemption from qualification) of any of the Registrable Securities for sale
  in any jurisdiction, at the earliest practicable moment. CBT shall,
  promptly following the occurrence of any event contemplated by clause (v),
  prepare a supplement or post-effective amendment to the registration
  statement or a supplement to the related prospectus or any document
  incorporated therein by reference or

<PAGE>

  file any other required document so that, as thereafter delivered to the
  purchasers of the Registrable Securities being sold thereunder, such
  prospectus will not contain an untrue statement of a material fact or omit
  to state a material fact necessary to make the statements therein, in light
  of the circumstances under which they were made, not misleading.

     (c) In connection with any offering of Registrable Securities registered
  pursuant to this Declaration, CBT shall (x) furnish Shareholders, at CBT's
  expense, with un-legended certificates representing ownership of the
  Registrable Securities being sold in such denominations as Shareholders
  shall request and (y) instruct the transfer agent and registrar of the
  Registrable Securities to release any stop transfer orders with respect to
  the Registrable Securities being sold.

   5. Availability of Form S-3. CBT represents that if Form S-3 (or a successor
form) is not available for use by CBT, CBT shall use its reasonable best
efforts to satisfy the requirements of Form S-3 at the earliest possible time.
CBT further represents that it believes it is currently eligible to utilize
Form S-3 and currently believes that there is no material nonpublic information
which would preclude it from filing a registration statement on Form S-3.

   6. Expenses. CBT shall pay all of the out-of-pocket expenses incurred in
connection with any registration of Registrable Securities pursuant to this
Declaration, including all SEC, NASD and blue sky registration and filing fees,
printing expenses, transfer agents' and registrars' fees, and the reasonable
fees and disbursements of CBT's outside counsel and independent accountants.
Notwithstanding the foregoing, Shareholders shall pay any and all brokerage
fees, applicable transfer taxes, if any (including stamp transfer taxes imposed
by Irish law) and depositary fees, if any, in connection with the deposit of
the Registrable Securities, if applicable, and the subsequent sale by
Shareholders of the Registrable Securities.

   7. Additional Obligations of CBT; Reports under the Exchange Act. CBT agrees
to:

     (a) use its reasonable best efforts to file with the SEC in a timely
  manner all reports and other documents required of CBT under the Securities
  Act and the Exchange Act; and

     (b) furnish to Shareholders forthwith upon request (i) a written
  statement by CBT that it has complied with the reporting requirements of
  the Securities Act and the Exchange Act, or that it qualifies as a
  registrant whose securities may be resold pursuant to Form S-3 (at any time
  after it so qualifies), (ii) a copy of the most recent annual or quarterly
  report of CBT and (iii) such other information as may be reasonably
  requested in availing Shareholders of any rule or regulation of the SEC
  which permits the selling of any Registrable Securities pursuant to Form S-
  3.

   8. Assignment of Registration Rights. The rights, duties and obligations of
CBT pursuant to this Declaration may not be assigned. The rights, duties and
obligations of Shareholders pursuant to this Declaration may not be assigned or
transferred except (x) by will or the laws of descent and distribution, or (y)
to a family member of a Shareholder, or a trust of which a family member is the
beneficiary; provided however, in the event of an assignment or transfer
pursuant to clauses (i), or (ii), such assignee or transferee gives CBT notice
that he, she or it is an assignee or transferee of Registrable Securities under
this Section 8, provides CBT with his, her or its name and address and the
number of Registrable Securities acquired, and agrees to be bound as a
Shareholder by all of the terms of this Declaration. Nothing herein shall be
construed to modify Shareholders' obligations under the Affiliate's Agreement
signed by Shareholders pursuant to the Share Purchase Agreement.

   9. Amendment of Registration Rights. The registration rights granted
hereunder may only be amended by a written amendment signed by Shareholders
holding a majority of the Registrable Securities and CBT.

   10. Termination. The registration rights set forth in this Declaration shall
terminate with respect to Shareholders (and the shares held by Shareholders
shall cease to constitute Registrable Securities) upon the earlier of (i) such
time as all of the Registrable Securities then held by Shareholders can be sold
by Shareholders in a three (3) month period in accordance with Rule 144 under
the Securities Act and (ii) the second anniversary of the closing of the Share
Exchange.

<PAGE>

   11. Obligations of Shareholders. By exercising any rights hereunder, a
Shareholder shall be deemed to assume all obligations hereunder as though such
Shareholder was a signatory hereto.

and superseded and governed by this Escrow Agreement.

                                    RECITALS

   WHEREAS, CBT, the Shareholders and KnowledgeWell have entered into a Share
Purchase Agreement dated as of November 30, 1998, as amended and restated as of
March 30, 1999 (the "Share Purchase Agreement").

   WHEREAS, Article VIII of the Share Purchase Agreement provides that the

contemplated by the Share Purchase Agreement.

   NOW, THEREFORE, in consideration of the promises contained herein and in the
Share Purchase Agreement and other good and valuable consideration, the receipt
of which is hereby acknowledged, the parties hereto agree as follows:

   1. Share Purchase Agreement. The Escrow Agent hereby acknowledges receipt of

not charged with any duties or responsibilities with respect thereto.
Capitalized terms used and not defined herein shall have the meanings set forth
in the Share Purchase Agreement unless the context requires otherwise.

   2. Purpose; Effectiveness. This Escrow Agreement has been executed and
delivered, and the deposit of the Escrow Amount hereunder will be made, for the
purpose of reimbursing and providing compensation for those Damages (as defined
in the Share Purchase Agreement) that CBT or any of its affiliates has incurred
or reasonably anticipates incurring by reason of any CBT Indemnifiable Claim
(as defined in the Share Purchase Agreement). Transfers of Escrow Shares (as
defined below) to Jack Hayes, as Trustee under the Trust Agreement attached
hereto as Exhibit A (the "Trust Agreement"), shall be the non-exclusive remedy
of CBT against each of the Shareholders for any such CBT Indemnifiable Claim.
This Escrow Agreement shall become effective at the Closing Date.

   3. Escrow Fund.

      (b) Upon effectiveness of this Escrow Agreement, CBT shall deliver or
cause to be delivered to the Escrow Agent such number of ADSs or Ordinary

<PAGE>

Agreement. Each Shareholder shall also execute and deliver an Irrevocable
Assignment Separate from Certificate in the form attached hereto as Exhibit B

the date of determination, remain subject to this Escrow Agreement. The Escrow
Agent shall not be required to inquire as to or examine the number of Escrow
Shares it receives pursuant to the Share Purchase Agreement. The Escrow Fund

hereinafter set forth.

      (b) Each Shareholder shall be responsible for any tax liability
attributable to the placement of the Escrow Shares in the escrow and the
payment of any dividends or other amounts payable to the Shareholders with
respect to the Escrow Shares. Each Shareholder, severally and not jointly,
agrees to assume any and all obligations relating to his, her or its Escrow
Shares imposed now or hereafter by any applicable tax law with respect to the
transfer of Escrow Shares under this Escrow Agreement, and to indemnify and
hold the Escrow Agent harmless from and against any liability relating to his,
her or its Escrow Shares on account of taxes, assessments, additions for late
payment, interest, penalties and other expenses, or other governmental charges
to which the Escrow Agent may be or become subject in connection with or which
arises out of this Escrow Agreement, including reasonable costs and expenses
(including reasonable legal fees and expenses), interest and penalties.

   4. Escrow Stock. The number of ADSs or Ordinary Shares representing the
Escrow Amount is listed on Schedule A hereto.

   5. Representative.

      (a) The Representative shall have full power and authority to represent
the Shareholders and their successors with respect to all matters arising under
this Escrow Agreement, including, without limitation, the execution and
delivery of any forms or other documents to effect a transfer of all or part of
the Escrow Shares to the Trustee pursuant to Section 7 hereof, and all actions
taken by the Representative hereunder shall be binding upon the Shareholders
and their successors as if expressly done by, or confirmed and ratified in
writing by, each of them. Without limiting the generality of the foregoing, the
Representative shall have full power and authority to interpret all the terms
and provisions of this Escrow Agreement and to consent to any amendment hereof
on behalf of the Shareholders and such successors. All action to be taken by
the Representative hereunder shall be taken by or at his or her written
direction or pursuant to such other method as the Representative, by written
notice to CBT and the Escrow Agent, shall designate.

      (b) The Representative may act upon any instrument or other writing
believed by such Representative in good faith to be genuine and to be signed or
presented by the proper person and shall not be liable in connection with the
performance by him or her of his or her duties pursuant to the provisions of
this Escrow Agreement, except for his or her own willful default or
recklessness. The Representative shall be, and hereby is, indemnified and saved
harmless, jointly and severally, by the Shareholders from all losses, costs and
expenses that may be incurred by the Representative as a result of such
Representative's involvement in any arbitration or litigation arising from
performance of his or her duties hereunder, provided that such arbitration or
litigation shall not result from any action taken or omitted by the
Representative as a result of his or her willful default or recklessness.

      (c) The Representative shall not be entitled to compensation for his or
her services rendered hereunder. However, the Representative shall be
reimbursed by Shareholders for reasonable counsel fees and other reasonable
out-of-pocket expenses incurred in connection with the provisions of this
Escrow Agreement.

      (d) The Representative, or any successor to him or her hereafter
appointed, may resign and shall be discharged of such Representative's duties
hereunder upon the appointment of a successor Representative as hereinafter
provided. In case of the Representative's resignation, death or inability to
act as Representative, upon receipt of notice thereof, a successor or
successors shall be named by the remaining Shareholders. Each successor
Representative shall have all the power, authority, rights and privileges
hereby conferred upon the original Representative, and the term
"Representative" as used herein shall be deemed to include each such successor
Representative.

<PAGE>

      (e) The Representative shall take all actions, execute all documents and
otherwise cooperate fully with any request by CBT or the Trustee to transfer
Escrow Shares as required by this Agreement or to otherwise effect the purpose
of this Escrow Agreement.

   6. Escrow Period; Distribution Upon Termination of Escrow Period. The Escrow
Fund shall remain in existence two (2) years after the Closing Date (the
"Escrow Period"). At the close of business on the date the Escrow Period
terminates (the "Termination Date"), the Escrow Period shall terminate with
respect to all of the Escrow Fund; provided, however, that the amount of the
Escrow Fund which in the reasonable judgment of the Special Committee of the
Board of Directors of CBT formed in connection with the Share Exchange (the
"Special Committee"), subject to objection of the Representative and the
subsequent arbitration of the matter in the manner provided in Section 7
hereof, is necessary to satisfy any unsatisfied CBT Indemnifiable Claim
specified in any Officer's Certificate (as hereafter defined) delivered to the
Escrow Agent prior to termination of the Escrow Period with respect to facts
and circumstances existing prior to the termination of such Escrow Period,
shall remain in the Escrow Fund (and the Escrow Fund shall remain in existence)
until such claims have been resolved. As soon as all such claims have been
resolved, the Escrow Agent shall deliver to the Shareholders all Escrow Shares
remaining in the Escrow Fund and not required to satisfy such claims. Any
delivery of Escrow Shares pursuant to this Section 6 shall be of full shares,
and the Escrow Agent shall sell the number of Escrow Shares that shall equal
the aggregate of all fractions to which the Shareholders would otherwise be
entitled. The Escrow Agent shall distribute the remaining Escrow Shares and the
proceeds of such sale to each Shareholders as is pro rata to his or her
proportional ownership in the KnowledgeWell Shares sold to CBT pursuant to the
Share Purchase Agreement; provided that, if a Shareholder shall have been
severally and not jointly liable for a CBT Indemnifiable Claim under the terms
of the Share Purchase Agreement, such Shareholder's pro rata distribution of
Escrow Shares shall be appropriately reduced.

   7. Assertion of Claims.

      (a) If any CBT Indemnitee shall incur Damages within the Escrow Period,
there shall be delivered to the Escrow Agent and the Representative a
certificate signed in good faith on behalf of CBT by an officer of CBT or by a
member of the Special Committee (an "Officer's Certificate") stating that a CBT
Indemnitee has paid, properly accrued, or reasonably anticipates that it will
have to pay or accrue Damages in an amount specified in such Officer's
Certificate, with the basis for such claim set forth in reasonable detail.
Subject to Sections 7(b), 7(c), 8 and 9 hereof, as soon as practicable (but not
earlier than fifteen (15) calendar days, nor later than thirty (30) calendar
days, after delivery to the Escrow Agent and the Representative of such
Officer's Certificate) the Escrow Agent shall transfer, deliver and assign to
Jack Hayes, as Trustee under the Trust Agreement, such number of the Escrow
Shares (rounded down to the nearest whole share) as is equal to the number
resulting from dividing the amount of such Damages by the closing price of an
ADS on the trading day immediately prior to the Closing Date, as reported on
the Nasdaq National Market. Each Officer's Certificate shall be delivered to
the Escrow Agent and the Representative in the manner specified in Section 11
hereof, and shall contain thereon a representation of the mailing of a copy
thereof to the Representative.

      (b) Unless, within fifteen (15) calendar days after delivery to the
Escrow Agent and the Representative of any Officer's Certificate, the
Representative gives written notice to CBT and the Escrow Agent, and said
written notice is received by both CBT and the Escrow Agent within said fifteen
(15) calendar day period, that he or she disputes in good faith the claim set
forth in such Officer's Certificate, with the basis for such dispute set forth
in reasonable detail, such Officer's Certificate shall constitute full
authority to the Escrow Agent to take the action provided for by the preceding
paragraph and shall be conclusive on all parties hereto. If the Representative
gives such notice, the Escrow Agent shall not transfer, deliver or assign to
the Trustee any Escrow Shares pursuant to this Section 7 until either (i) it
receives the written consent of the Representative or (ii) there is a final
decision of an arbitration panel appointed in accordance with the provisions of
Section 9 and the Escrow Agent receives the written final decision in
accordance with Section 9 hereof.

      (c) Nothing in this Escrow Agreement shall create or be deemed to create
any interest by way of charge or otherwise in favor of CBT in the Escrow Shares
or Escrow Fund.

<PAGE>

   8. Third-Party Claims. In the event CBT becomes aware of a third-party claim
which CBT believes may result in a demand against the Escrow Fund, CBT shall
notify the Representative of such claim, and any of the Representative or each
Shareholder shall be entitled, at their individual expense, to participate in
any defense of such claim. Delay in providing such notice shall not eliminate
such claim except to extent that the Shareholders are prejudiced thereby. CBT
shall have the right in its sole discretion to settle any such claim; provided,
however, that except with the consent of the Representative, no settlement of
any such claim with third-party claimants shall be determinative of the
validity and quantum of any claim against the Escrow Fund. In the event that
the Representative has consented to any such settlement, the Representative
shall have no power or authority to object under any provision of this Escrow
Agreement to the amount of any claim by CBT against the Escrow Fund with
respect to such settlement.

   9. Arbitration. If the Representative delivers to CBT and the Escrow Agent a
timely notice pursuant to Section 7(b) above disputing in good faith the amount
of any claim or that any claim is covered hereby or if any other dispute arises
with respect to this Escrow Agreement, then a CBT (in consultation with the
members of the Special Committee) and the Representative shall use their best
efforts to resolve such dispute. In the event of resolution of such dispute,
CBT and the Representative shall both execute a memorandum setting forth such
resolution and, if applicable, the amount of any damages payable to the Trustee
on behalf of CBT, and shall furnish such memorandum to the Escrow Agent. In the
event CBT and the Representative are unable to resolve such dispute within
twenty (20) calendar days from CBT's receipt of the Representative's written
notice disputing a claim or from the date of receipt of written notice with
respect to any other dispute arising with respect to this Escrow Agreement,
then either party may demand, by written notice to the other, that such issue
shall be settled by binding arbitration to be held in San Francisco, California
(an "Arbitration Demand"). All claims shall be settled by three arbitrators in
accordance with the Commercial Arbitration Rules then in effect of the American
Arbitration Association (the "Arbitration Rules"). The Representative and CBT
shall each designate one (1) arbitrator within fifteen (15) calendar days after
the delivery of the Arbitration Demand. Such designated arbitrators shall
mutually agree upon and shall designate a third arbitrator (the "third
arbitrator"). The final decision of a majority of the arbitrators shall be
furnished to the Representative, CBT and the Escrow Agent in writing and shall
constitute a conclusive determination of the issue in question, binding upon
all parties and shall not be contested by any of them. Each party shall bear
its own fees (including its designated arbitrator's fees and attorney's fees)
and other expenses associated with the arbitration. The non-prevailing party
shall bear all other fees and costs associated with such arbitration, except
that the parties shall each pay fifty percent (50%) of the fees of the third
arbitrator.

   10. Adjustments to Escrow Shares; Dividends; Voting.

       (a) If the Escrow Agent shall receive any securities in respect of or in
exchange for any of the Escrow Shares held by it, whether by way of dividends,
share splits, recapitalizations, liquidations, mergers, consolidations, split-
ups, spin-offs, redemptions, exchanges or conversions of shares and the like
("New Shares"), the Escrow Agent shall hold in escrow such securities and the
same shall be subject to all of the provisions of this Escrow Agreement
relating to the Escrow Fund. Notwithstanding the foregoing, the Shareholders
shall retain the rights to receive any cash dividends or distributions payable
with respect to their Escrow Shares, and such cash dividends or distributions
shall be distributed currently to the Shareholders. New Shares issued in
respect of Escrow Shares which have been released from the Escrow Fund, if any,
shall not be added to the Escrow Fund, but shall be distributed to the holders
of such released Escrow Shares.

       (b) Each Shareholder shall have all voting rights with respect to the
Escrow Shares contributed to the Escrow Fund on behalf of each of them for so
long as such Escrow Shares are held in the Escrow Fund.

   12. Escrow Agent's Protection. In performing any duties under this
Agreement, the Escrow Agent shall not be liable to any party for consequential
damages, (including, without limitation lost profits) losses, or expenses,
except for gross negligence or willful misconduct on the part of the Escrow
Agent. The Escrow Agent shall not incur any such liability for (i) any act or
failure to act made or omitted in good faith, or (ii) any action taken or
omitted in reliance upon any written instrument, including any written
statement or affidavit provided for in this Agreement that the Escrow Agent
shall in good faith believe to be genuine, nor will the

<PAGE>

Escrow Agent be liable or responsible for forgeries, fraud, impersonations, or
determining the scope of any representative authority. The Escrow Agent shall
not act on the oral instructions of any party. In addition, the Escrow Agent
may consult with legal counsel in connection with the Escrow Agent's duties
under this Escrow Agreement and shall be fully protected in any act taken,
suffered, or permitted by him/her in good faith in accordance with the advice
of counsel. The Escrow Agent is not responsible for determining and verifying
the authority of any person acting or purporting to act on behalf of any party
to this Escrow Agreement.

   13. Controversies. If any controversy arises among the parties to this
Escrow Agreement, or with any other party, concerning the subject matter of

required to determine the controversy or to take any action regarding it. The
Escrow Agent may hold all documents and Escrow Shares and may wait for
settlement of any such controversy pursuant to the provisions of Section 9 of
this Escrow Agreement. In such event, the Escrow Agent will not be liable for
interest or damages. Furthermore, the Escrow Agent may, at its option, file an
action of interpleader requiring the parties to such controversy to answer and
arbitrate pursuant to Section 9 of this Escrow Agreement any claims and rights
among themselves. The Escrow Agent is authorized to deposit with the clerk of
the court all documents and Escrow Shares held in escrow, except all costs,
expenses, charges and reasonable attorney fees incurred by the Escrow Agent due

losses, claims, damages, liabilities, and expenses, including reasonable costs
of investigation, counsel fees, including allocated costs of in-house counsel
and disbursements that may be imposed on the Escrow Agent or incurred by the
Escrow Agent in connection with the performance of his or her duties under this
Escrow Agreement, including but not limited to any litigation arising from this
Escrow Agreement or involving its subject matter (but excluding any and all
losses, claims, damages, liabilities, and expenses attributable to the gross
negligence or wilful misconduct of the Escrow Agent).

   15. Escrow Agent Fees. Reasonable fees and expenses for the services
rendered by the Escrow Agent pursuant to the provisions of this Escrow
Agreement (including reasonable fees and disbursements of its counsel incurred
in connection with the performance by it of such services) shall be paid to the
Escrow Agent. Such fees and expenses shall be paid by CBT.

   16. Successor Escrow Agent. The Escrow Agent may resign at any time upon
giving at least thirty (30) days written notice to CBT and the Representative;
provided, however, that no such resignation shall become effective until the
appointment of a successor escrow agent, which shall be accomplished as
hereinafter provided. CBT and the Representative shall use their best efforts

receiving such notice. If CBT and the Representative fail to agree upon a
successor escrow agent within such time, the Escrow Agent shall have the right
to appoint a successor escrow agent, which shall be a bank or trust company
organized under the laws of the United States of America or of the State of
California and have a combined capital and surplus of not less than
US$10,000,000. The successor escrow agent shall execute and deliver to CBT and
the Representative a written instrument accepting such appointment and it
shall, without further acts, be vested with the estates, properties, rights,
powers, and duties of the predecessor Escrow Agent as if originally named as
Escrow Agent. Upon such appointment, the Escrow Agent shall be discharged from
any further duties and liability under this Agreement.

representatives, and the Representative and his or her successors.

     APPLICABLE SECURITIES LAWS OF THE UNITED STATES AND ANY STATE OF

     SATISFACTORY WRITTEN OPINION FROM U.S. COUNSEL, AND (C) IN EACH
     CASE UPON THE DELIVERY OF A TRANSFER CERTIFICATE SUBSTANTIALLY IN
     THE FORM ATTACHED TO THE RESTRICTED DEPOSIT AGREEMENT AS ANNEX II
     DULY EXECUTED AND COMPLETED BY THE TRANSFEROR. THE BENEFICIAL
     OWNER OF ORDINARY SHARES RECEIVED UPON CANCELLATION OF ANY
     RESTRICTED AMERICAN DEPOSITARY RECEIPTS MAY NOT DEPOSIT OR CAUSE
     TO BE DEPOSITED SUCH ORDINARY SHARES INTO ANY DEPOSITARY RECEIPT
     FACILITY ESTABLISHED OR MAINTAINED BY A DEPOSITARY BANK
     (INCLUDING ANY SUCH FACILITY MAINTAINED BY THE DEPOSITARY FOR THE
     RESTRICTED AMERICAN DEPOSITARY RECEIPTS), OTHER THAN A RESTRICTED
     DEPOSITARY RECEIPT FACILITY, SO LONG AS SUCH ORDINARY SHARES ARE
     "RESTRICTED SECURITIES" WITHIN THE MEANING OF RULE 144(a)(3)
     UNDER THE SECURITIES ACT OR ARE OTHERWISE SUBJECT TO THE TRANSFER
     RESTRICTIONS OF RULE 144 OR RULE 145 UNDER THE SECURITIES ACT.
     EACH OWNER AND BENEFICIAL OWNER, BY ITS ACCEPTANCE OF THIS
     RESTRICTED AMERICAN DEPOSITARY RECEIPT, REPRESENTS AND AGREES

be required by the Depositary or required to comply with any applicable law or
regulations thereunder or with the rules and regulations of any securities
exchange upon which Restricted American Depositary Shares may be listed or to
conform with any usage with respect thereto, or to indicate any special
limitations or restrictions to which any particular Receipts are subject by
reason of the date of issuance of the underlying Deposited Securities or
otherwise.

          The Receipts shall bear a CUSIP number that is different from any
CUSIP number that is or may be assigned any other depositary receipt facility
relating to the Shares.

Shares evidenced thereby), when properly endorsed or accompanied by proper
instruments of transfer, and transferred in accordance with the terms of this
Restricted Deposit Agreement, including without limitation Sections 2.04, 2.06
and 2.09, shall be transferable by delivery with the same effect as in the case
of a negotiable instrument

under the laws of New York; provided, however, that the Depositary,
                            --------  -------
notwithstanding any notice to the contrary, may treat the Owner thereof as the
absolute owner thereof for the purpose of determining the person entitled to
distribution of dividends or other distributions or to any notice provided for
in this Restricted Deposit Agreement and for all other purposes.

          SECTION 2.02.  Deposit of Shares.  (a) Subject to the terms and
                         -----------------
conditions of this Restricted Deposit Agreement, Shares may be deposited under
this Restricted Deposit Agreement by delivery thereof to any Custodian
hereunder, accompanied by any appropriate instrument or instruments of transfer,
or endorsement, in form satisfactory to the Custodian, together with a duly
executed and completed written certification and agreement ("Depositor
Certificate"), in substantially the form attached as Annex I hereto, by the
beneficial owner of the Restricted American Depositary Shares to be issued upon
deposit of such Shares, and all such certifications or opinions of counsel as
may be required by the Depositary or the Custodian in accordance with the
provisions of this Restricted Deposit Agreement, and, if the Depositary
requires, together with a written order directing the Depositary to execute and
deliver to, or upon the written order of, the person or persons stated in such
order (which shall be the beneficial owner furnishing the Depositor
Certificate), a Receipt or Receipts for the number of Restricted American
Depositary Shares representing such deposit.

          No Share shall be accepted for deposit unless accompanied by evidence
satisfactory to the Depositary that any necessary approval has been granted by
any governmental body in The Republic of Ireland which is then performing the
function of the regulation of currency exchange. If required by the Depositary,
Shares presented for deposit at any time, whether or not the transfer books of
the Company or the Foreign Registrar, if applicable, are closed, shall also be
accompanied by an agreement or assignment, or other instrument satisfactory to
the Depositary, which will provide for the prompt transfer to the Custodian of
any dividend, or right to subscribe for additional Shares or to receive other
property which any person in whose name the Shares are or have been recorded may
thereafter receive upon or in respect of such deposited Shares, or in lieu
thereof, such agreement of indemnity or other agreement as shall be satisfactory
to the Depositary.

          At the request and risk and expense of any person proposing to deposit
Shares, and for the account of such person, the Depositary may receive
certificates for Shares to be deposited, together with the other instruments
herein specified, for the purpose of forwarding such Share certificates to the
Custodian for deposit hereunder.

          Upon each delivery to a Custodian of a certificate or certificates for
Shares to be deposited hereunder, together with the other documents above
specified, such Custodian shall, as soon as transfer and recordation can be
accomplished, present such

                                      -7-
<PAGE>

certificate or certificates to the Company or the Foreign Registrar, if
applicable, for transfer and recordation of the Shares being deposited in the
name of the Depositary or its nominee or such Custodian or its nominee.

          (b) Deposited Securities shall be held by the Depositary or by a
Custodian for the account and to the order of the Depositary or at such other
place or places as the Depositary shall determine. The Depositary agrees to
instruct the Custodian to place all Shares accepted for deposit under this
Restricted Deposit Agreement into segregated accounts separate from any Shares
of the Company that may be held by such Custodian under any other depositary
receipt facility relating to the Shares.

          SECTION 2.03.  Execution and Delivery of Receipts.  Upon receipt by
                         ----------------------------------
any Custodian of any deposit pursuant to Section 2.02 hereunder (and in
addition, if the transfer books of the Company or the Foreign Registrar, if
applicable, are open, the Depositary may in its sole discretion require a proper
acknowledgment or other evidence from the Company that any Deposited Securities
have been recorded upon the books of the Company or the Foreign Registrar, if
applicable, in the name of the Depositary or its nominee or such Custodian or
its nominee), together with the other documents required as above specified,
such Custodian shall notify the Depositary of such deposit and the person or
persons to whom or upon whose written order a Receipt or Receipts are
deliverable in respect thereof and the number of Restricted American Depositary
Shares to be evidenced thereby. Such notification shall be made by letter or, at
the request, risk and expense of the person making the deposit, by cable, telex
or facsimile transmission. Upon receiving such notice from such Custodian, or
upon the receipt of Shares by the Depositary, in either case together with a
duly executed and completed Depositor Certificate in substantially the form
attached hereto as Annex I, the Depositary, subject to the terms and conditions
of this Restricted Deposit Agreement, shall execute and deliver at its Corporate
Trust Office, to or upon the order of the person or persons named in the notice
delivered to the Depositary (which shall be the beneficial owner furnishing the
Depositor Certificate), a Receipt or Receipts, registered in the name or names
and evidencing any authorized number of Restricted American Depositary Shares
requested by such person or persons, but only upon payment to the Depositary of
the fees and expenses of the Depositary for the execution and delivery of such
Receipt or Receipts as provided in Section 5.09, and of all taxes and
governmental charges and fees payable in connection with such deposit and the
transfer of the Deposited Securities.

          SECTION 2.04.  Transfer of Receipts; Combination and Split-up of
                         -------------------------------------------------
Receipts.  Upon receipt by the Depositary of (a) a written opinion of U.S.
- --------
counsel satisfactory to the Depositary in connection with a transfer pursuant to
an effective registration statement registering the resale of the Restricted
American Depositary Shares or in accordance with paragraphs (c), (e), (f), (g)
and, if applicable, (h) of Rule 144 under the Securities Act, pursuant to either
Rule 144 or Rule 145 under the Securities Act,

                                      -8-
<PAGE>

without regard to any termination of certain restrictions by operation of
paragraph (k) of that rule, and (b) a duly executed and completed written
certification and agreement ("Transfer Certificate"), in substantially the form
attached as Annex II hereto and as hereinafter described, in connection with a
transfer pursuant to an effective registration statement registering the resale
of the Restricted American Depositary Shares or in accordance with paragraphs
(c), (e), (f), (g) and, if applicable, (h) of Rule 144 under the Securities Act,
without regard to any termination of certain restrictions by operation of
paragraph (k) of that rule, the Depositary, subject to the terms and conditions
of this Restricted Deposit Agreement, including payment of the fees of the
Depositary as provided in Section 5.09, shall exchange, upon any surrender of a
Receipt, by the Owner in person or by a duly authorized attorney, properly
endorsed or accompanied by proper instruments of transfer, and duly stamped as
may be required by the laws of the State of New York and of the United States of
America, the Receipts evidencing Restricted American Depositary Shares for ADRs
evidencing ADSs issued pursuant to the ADR Deposit Agreement, subject to the
provisions of Section 2.09 of this Restricted Deposit Agreement. The Depositary
shall not be required to register any transfer of a Receipt unless it shall have
received from the Beneficial Owner a duly executed and completed Transfer
Certificate, in form and substance satisfactory to the Depositary.

          The Depositary, subject to the terms and conditions of this Restricted
Deposit Agreement, including, if the Depositary shall so require, delivery of a
written opinion of U.S. counsel and a duly executed and completed Transfer
Certificate substantially in the form of Annex II hereto, shall upon surrender
of a Receipt or Receipts for the purpose of effecting a split-up or combination
of such Receipt or Receipts, execute and deliver a new Receipt or Receipts for
any authorized number of Restricted American Depositary Shares requested,
evidencing the same aggregate number of Restricted American Depositary Shares as
the Receipt or Receipts surrendered.

          The representations and warranties included within the Transfer
Certificate in the form of Annex II to be delivered shall survive such transfer,
surrender and withdrawal, split-up or combination of the Shares or Receipts.

          The Depositary may appoint one or more co-transfer agents for the
purpose of effecting transfers, combinations and split-ups of Receipts at
designated transfer offices on behalf of the Depositary.  In carrying out its
functions, a co-transfer agent may require evidence of authority and compliance
with applicable laws and other requirements by Owners or persons entitled to
Receipts and will be entitled to protection and indemnity to the same extent as
the Depositary.

          SECTION 2.05.  Surrender of Receipts and Withdrawal of Shares.  Upon
                         ----------------------------------------------
surrender of a Receipt at the Corporate Trust Office of the Depositary for the
purpose of withdrawal of the Deposited Securities represented by the Restricted
American

                                      -9-
<PAGE>

Depositary Shares evidenced by such Receipt, and upon payment of the fee of the
Depositary for the surrender of Receipts as provided in Section 5.09 and payment
of all taxes and governmental charges payable in connection with such surrender
and withdrawal of the Deposited Securities, and subject to the terms and
conditions of this Restricted Deposit Agreement, the Owner of such Receipt shall
be entitled to delivery, to him or upon his order, of the amount of Deposited
Securities at the time represented by the Restricted American Depositary Shares
evidenced by such Receipt. Delivery of such Deposited Securities may be made by
the delivery of (a) certificates in the name of such Owner or as ordered by him
or certificates properly endorsed or accompanied by proper instruments of
transfer to such Owner or as ordered by him and (b) any other securities,
property and cash to which such Owner is then entitled in respect of such
Receipts to such Owner or as ordered by him. Such delivery shall be made, as
hereinafter provided, without unreasonable delay.

          Notwithstanding the foregoing, no Deposited Securities may be
withdrawn upon the surrender of a Receipt unless at or prior to the time of
surrender, the Depositary shall have received (a) a written opinion of U.S.
counsel satisfactory to the Depositary, and (b) a duly executed and completed
written certificate and agreement ("Withdrawal Certificate"), in substantially
the form attached as Annex III hereto, by or on behalf of the person
surrendering such Receipt who after such withdrawal will be the beneficial owner
of such Deposited Securities; provided, however, that no Withdrawal Certificate
                              --------  -------
shall be required for a withdrawal in connection with a transfer pursuant to an
effective registration statement registering the resale of the Restricted
American Depositary Shares or in accordance with paragraphs (c), (e), (f), (g)
and, if applicable, (h) of Rule 144 under the Securities Act, pursuant to either
Rule 144 or Rule 145 under the Securities Act, without regard to any termination
of certain restrictions by operation of paragraph (k) of that Rule, in which
case the terms and provisions of Section 2.09 of this Restricted Deposit
Agreement shall apply.

          A Receipt surrendered for such purposes may be required by the
Depositary to be properly endorsed in blank or accompanied by proper instruments
of transfer in blank, and if the Depositary so requires, the Owner thereof shall
execute and deliver to the Depositary a written order directing the Depositary
to cause the Deposited Securities being withdrawn to be delivered to or upon the
written order of a person or persons designated in such order. Thereupon the
Depositary shall direct the Custodian to deliver at the Dublin, Ireland office
of such Custodian, subject to Sections 2.06, 3.01 and 3.02 and to the other
terms and conditions of this Restricted Deposit Agreement, to or upon the
written order of the person or persons designated in the order delivered to the
Depositary as above provided, the amount of Deposited Securities represented by
the Restricted American Depositary Shares evidenced by such Receipt, except that
the Depositary may make delivery to such person or persons at the Corporate
Trust Office of the Depositary of any dividends or distributions with respect to
the Deposited Securities

                                      -10-
<PAGE>

represented by the Restricted American Depositary Shares evidenced by such
Receipt, or of any proceeds of sale of any dividends, distributions or rights,
which may at the time be held by the Depositary.

          At the request, risk and expense of any Owner so surrendering a
Receipt, and for the account of such Owner, the Depositary shall direct the
Custodian to forward any cash or other property (other than rights) comprising,
and forward a certificate or certificates and other proper documents of title
for, the Deposited Securities represented by the Restricted American Depositary
Shares evidenced by such Receipt to the Depositary for delivery at the Corporate
Trust Office of the Depositary.  Such direction shall be given by letter or, at
the request, risk and expense of such Owner, by cable, telex or facsimile
transmission.

          Notwithstanding the foregoing, each Owner acknowledges that, and each
of the Depositary and Custodian agrees that, neither the Custodian nor the
Depositary will make any actual delivery of Shares to any Owner at an address
within the United States.

          SECTION 2.06.  Limitations on Execution and Delivery, Transfer and
                         ---------------------------------------------------
Surrender of Receipts.  As a condition precedent to the execution and delivery,
- ---------------------
registration of transfer, split-up, combination or surrender of any Receipt or
withdrawal of any Deposited Securities, the Depositary, Custodian or Registrar
may require payment from the depositor of Shares or the presenter of the Receipt
of a sum sufficient to reimburse it for any tax or other governmental charge and
any stock transfer or registration fee with respect thereto (including any such
tax or charge and fee with respect to Shares being deposited or withdrawn) and
payment of any applicable fees as herein provided, may require the production of
proof satisfactory to it as to the identity and genuineness of any signature and
may also require compliance with any regulations the Depositary may establish
consistent with the provisions of this Restricted Deposit Agreement, including,
without limitation, this Section 2.06.

          The delivery of Receipts against deposit of Shares generally or
against deposit of particular Shares may be suspended, or the transfer of
Receipts in particular instances may be refused, or the registration of transfer
of outstanding Receipts generally may be suspended, during any period when the
transfer books of the Depositary are closed, or if any such action is deemed
necessary or advisable by the Depositary or the Company at any time or from time
to time because of any requirement of law or of any government or governmental
body or commission, or under any provision of this Restricted Deposit Agreement,
or for any other reason.

          SECTION 2.07.  Lost Receipts, etc.  In case any Receipt shall be
                         -------------------
mutilated, destroyed, lost or stolen, the Depositary shall execute and deliver a
new Receipt of like tenor in exchange and substitution for such mutilated
Receipt upon

                                      -11-
<PAGE>

cancellation thereof, or in lieu of and in substitution for such destroyed, lost
or stolen Receipt. Before the Depositary shall execute and deliver a new Receipt
in substitution for a destroyed, lost or stolen Receipt, the Owner thereof shall
have (a) filed with the Depositary (i) a request for such execution and delivery
before the Depositary has notice that the Receipt has been acquired by a bona
fide purchaser and (ii) a sufficient indemnity bond and (b) satisfied any other
reasonable requirements imposed by the Depositary.

          SECTION 2.08.  Cancellation and Destruction of Surrendered Receipts.
                         ----------------------------------------------------
All Receipts surrendered to the Depositary shall be cancelled by the Depositary.
The Depositary is authorized to destroy Receipts so cancelled.

          SECTION 2.09.  Exchange of Restricted American Depositary Shares for
                         -----------------------------------------------------
ADSs.
- ----

          (a)  Subject to applicable law and the terms and conditions of this
Restricted Deposit Agreement, upon receipt by the Depositary of a written
opinion of U.S. counsel satisfactory to the Depositary and a duly executed and
completed Transfer Certificate pursuant to Section 2.04 of this Restricted
Deposit Agreement, Restricted American Depositary Shares sold or otherwise
transferred pursuant to an effective registration statement registering the
resale of the Restricted American Depositary Shares or in accordance with
paragraphs (c), (e), (f), (g) and, if applicable, (h) of Rule 144 under the
Securities Act, pursuant to either Rule 144 or Rule 145 under the Securities
Act, without regard to any termination of certain restrictions by operation of
paragraph (k) of that Rule, shall be exchanged for ADSs issued pursuant to the
ADR Deposit Agreement. In connection therewith, the Depositary shall (i) cancel
such Restricted American Depositary Shares issued hereunder and issue a
corresponding number of ADSs pursuant to the ADR Deposit Agreement to the Owners
entitled thereto and (ii) make arrangements to transfer any position held under
the CUSIP number relating to the Restricted American Depositary Shares issued
hereunder to the CUSIP number relating to such ADSs issued under the ADR Deposit
Agreement. The Depositary shall further instruct the Custodian to deliver all
such Deposited Securities held by it hereunder to the custodian under the ADR
Deposit Agreement for deposit thereunder. The transferees of interests of Owners
and Beneficial Owners of Receipts hereunder shall thereafter be owners and
beneficial owners of ADRs issued pursuant to the ADR Deposit Agreement and shall
have all of the rights and obligations set forth under the ADR Deposit Agreement
and the ADRs. In connection with an Exchange, all Owners and Beneficial Owners
of Receipts issued hereunder shall be deemed to have made the representations
and warranties set forth in Section 3.03 of the ADR Deposit Agreement.

          (b)  Each Owner and Beneficial Owner acknowledges and agrees that
there can be no assurance that applicable laws will permit the Depositary to
effect an Exchange as described in paragraph (a) above. In the event that the
Depositary determines in its

                                      -12-
<PAGE>

sole discretion that an Exchange cannot be so effected, the Depositary and the
Company shall negotiate in good faith to amend the Restricted Deposit Agreement
as they deem necessary to either (i) permit an Exchange on such terms as they
may agree in accordance with applicable law or (ii) make such other arrangements
as they deem desirable.


                                   ARTICLE 3

                  CERTAIN OBLIGATIONS OF OWNERS AND BENEFICIAL
                               OWNERS OF RECEIPTS

          SECTION 3.01.  Filing Proofs, Certificates and Other Information.  Any
                         -------------------------------------------------
person presenting Shares for deposit or any Owner or Beneficial Owner of a
Receipt may be required from time to time to file with the Depositary or the
Custodian such proof of citizenship or residence, exchange control approval, or
such information relating to the registration on the books of the Company or the
Foreign Registrar, if applicable, to execute such certificates and to make such
representations and warranties, as the Depositary may deem necessary or proper.
The Depositary may withhold the delivery or registration of transfer of any
Receipt or the distribution of any dividend or sale or distribution of rights or
of the proceeds thereof or the delivery of any Deposited Securities until such
proof or other information is filed or such certificates are executed or such
representations and warranties made. The Depositary shall, at the request of the
Company, advise the Company of the availability of any such proofs, certificates
or other information and shall provide copies thereof to the Company as promptly
as practicable upon request by the Company, unless such disclosure is prohibited
by law.

          SECTION 3.02.  Liability of Owner or Beneficial Owner for Taxes.  If
                         ------------------------------------------------
any tax or other governmental charge shall become payable by the Custodian or
the Depositary with respect to any Receipt or any Deposited Securities
represented by any Receipt, such tax or other governmental charge shall be
payable by the Owner or Beneficial Owner of such Receipt to the Depositary. The
Depositary may refuse to effect any transfer of such Receipt or any withdrawal
of Deposited Securities represented by Restricted American Depositary Shares
evidenced by such Receipt until such payment is made, and may withhold any
dividends or other distributions, or may sell for the account of the Owner or
Beneficial Owner thereof any part or all of the Deposited Securities represented
by the Restricted American Depositary Shares evidenced by such Receipt, and may
apply such dividends or other distributions or the proceeds of any such sale in
payment of such tax or other governmental charge and the Owner or Beneficial
Owner of such Receipt shall remain liable for any deficiency.

          SECTION 3.03.  Warranties on Deposit of Shares.  Every person
                         -------------------------------
depositing Shares under this Restricted Deposit Agreement shall be deemed
thereby to

                                      -13-
<PAGE>

represent and warrant, in addition to such representations and warranties as are
set forth in the Depositor Certificate, that such Shares and each certificate
therefor are validly issued, fully paid, nonassessable and free of any
preemptive rights of the holders of outstanding Shares and that the person
making such deposit is duly authorized so to do. Such representations and
warranties shall survive the deposit of Shares and issuance of Receipts.


                                   ARTICLE 4

                           THE DEPOSITED SECURITIES

          SECTION 4.01.  Cash Distributions.  Whenever the Depositary shall
                         ------------------
receive any cash dividend or other cash distribution on any Deposited
Securities, the Depositary shall, subject to the provisions of Section 4.05,
convert such dividend or distribution into Dollars and shall distribute the
amount thus received (net of the fees and expenses of the Depositary as provided
in Section 5.09) to the Owners entitled thereto, in proportion to the number of
Restricted American Depositary Shares representing such Deposited Securities
held by them respectively; provided, however, that in the event that the Company
                           --------  -------
or the Depositary shall be required to withhold and does withhold from such cash
dividend or such other cash distribution an amount on account of taxes, the
amount distributed to the Owner of the Receipts evidencing Restricted American
Depositary Shares representing such Deposited Securities shall be reduced
accordingly.  The Depositary shall distribute only such amount, however, as can
be distributed without attributing to any Owner a fraction of one cent.  Any
such fractional amounts shall be rounded to the nearest whole cent and so
distributed to Owners entitled thereto.  The Company or its agent will remit to
the appropriate governmental agency in The Republic of Ireland all amounts
withheld and owing to such agency.  The Depositary will forward to the Company
or its agent such information from its records as the Company may reasonably
request to enable the Company or its agent to file necessary reports with
governmental agencies, and the Depositary or the Company or its agent may file
any such reports necessary to obtain benefits under the applicable tax treaties
for the Owners of Receipts.

          SECTION 4.02.  Distributions Other Than Cash, Shares or Rights.
                         -----------------------------------------------
Subject to the provisions of Sections 4.11 and 5.09, whenever the Depositary
shall receive any distribution other than a distribution described in Section
4.01, 4.03 or 4.04, the Depositary shall cause the securities or property
received by it to be distributed to the Owners entitled thereto, after deduction
or upon payment of any fees and expenses of the Depositary or any taxes or other
governmental charges, in proportion to the number of Restricted American
Depositary Shares representing such Deposited Securities held by them
respectively, in any manner that the Depositary may deem equitable and
practicable

                                      -14-
<PAGE>

for accomplishing such distribution; provided, however, that if in the opinion
                                     --------  -------
of the Depositary such distribution cannot be made proportionately among the
Owners entitled thereto, or if for any other reason (including, but not limited
to, any requirement that the Company or the Depositary withhold an amount on
account of taxes or other governmental charges or that such securities must be
registered under the Securities Act in order to be distributed to Owners or
Beneficial Owners) the Depositary deems such distribution not to be feasible,
the Depositary may adopt such method as it may deem equitable and practicable
for the purpose of effecting such distribution, including, but not limited to,
the public or private sale of the securities or property thus received, or any
part thereof, and the net proceeds of any such sale (net of the fees and
expenses of the Depositary as provided in Section 5.09) shall be distributed by
the Depositary to the Owners entitled thereto, all in the manner and subject to
the conditions described in Section 4.01. Each beneficial owner of Receipts or
Shares so distributed shall be deemed to have acknowledged that the Shares have
not been registered under the Securities Act and to have agreed to comply with
the restrictions on transfer described in the form of legend set forth in
Section 2.01 hereof.

          SECTION 4.03.  Distributions in Shares.  If any distribution upon any
                         -----------------------
Deposited Securities consists of a dividend in, or free distribution of, Shares,
the Depositary may distribute to the Owners of outstanding Receipts entitled
thereto, in proportion to the number of Restricted American Depositary Shares
representing such Deposited Securities held by them respectively, additional
Receipts evidencing an aggregate number of Restricted American Depositary Shares
representing the amount of Shares received as such dividend or free
distribution, subject to the terms and conditions of the Restricted Deposit
Agreement with respect to the deposit of Shares and the issuance of Restricted
American Depositary Shares evidenced by Receipts, including the withholding of
any tax or other governmental charge as provided in Section 4.11 and the payment
of the fees and expenses of the Depositary as provided in Section 5.09.  The
Depositary may withhold any such distribution of Receipts if it has not received
satisfactory assurances from the Company that such distribution does not require
registration under the Securities Act or is exempt from registration under the
provisions of such Act.  In lieu of delivering Receipts for fractional
Restricted American Depositary Shares in any such case, the Depositary shall
sell the amount of Shares represented by the aggregate of such fractions and
distribute the net proceeds, all in the manner and subject to the conditions
described in Section 4.01.  If additional Receipts are not so distributed, each
Restricted American Depositary Share shall thenceforth also represent the
additional Shares distributed upon the Deposited Securities represented thereby.
Each beneficial owner of Receipts or Shares so distributed shall be deemed to
have acknowledged that the Shares have not been registered under the Securities
Act and to have agreed to comply with the restrictions on transfer described in
the form of legend set forth in Section 2.01 hereof.

                                      -15-
<PAGE>

          SECTION 4.04.  Rights.  In the event that the Company shall offer or
                         ------
cause to be offered to the holders of any Deposited Securities any rights to
subscribe for additional Shares or any rights of any other nature, the
Depositary shall have discretion as to the procedure to be followed in making
such rights available to any Owners or in disposing of such rights on behalf of
any Owners and making the net proceeds available to such Owners or, if by the
terms of such rights offering or for any other reason, the Depositary may not
either make such rights available to any Owners or dispose of such rights and
make the net proceeds available to such Owners, then the Depositary shall allow
the rights to lapse.  If at the time of the offering of any rights the
Depositary determines in its discretion that it is lawful and feasible to make
such rights available to all or certain Owners but not to other Owners, the
Depositary may distribute to any Owner to whom it determines the distribution to
be lawful and feasible, in proportion to the number of Restricted American
Depositary Shares held by such Owner, warrants or other instruments therefor in
such form as it deems appropriate.

          In circumstances in which rights would otherwise not be distributed,
if an Owner of Receipts requests the distribution of warrants or other
instruments in order to exercise the rights allocable to the Restricted American
Depositary Shares of such Owner hereunder, the Depositary will make such rights
available to such Owner upon written notice from the Company to the Depositary
that (a) the Company has elected in its sole discretion to permit such rights to
be exercised and (b) such Owner has executed such documents as the Company has
determined in its sole discretion are reasonably required under applicable law.

          If the Depositary has distributed warrants or other instruments for
rights to all or certain Owners, then upon instruction from such an Owner
pursuant to such warrants or other instruments to the Depositary from such Owner
to exercise such rights, upon payment by such Owner to the Depositary for the
account of such Owner of an amount equal to the purchase price of the Shares to
be received upon the exercise of the rights, and upon payment of the fees and
expenses of the Depositary and any other charges as set forth in such warrants
or other instruments, the Depositary shall, on behalf of such Owner, exercise
the rights and purchase the Shares, and the Company shall cause the Shares so
purchased to be delivered to the Depositary on behalf of such Owner.  As agent
for such Owner, the Depositary will cause the Shares so purchased to be
deposited pursuant to Section 2.02 of this Restricted Deposit Agreement, and
shall, pursuant to Section 2.03 of this Restricted Deposit Agreement, execute
and deliver Receipts to such Owner.  In the case of a distribution pursuant to
the second paragraph of this section, such Receipts shall be legended in
accordance with applicable U.S. laws, and shall be subject to the appropriate
restrictions on sale, deposit, cancellation, and transfer under such laws.

          If the Depositary determines in its discretion that it is not lawful
and feasible to make such rights available to all or certain Owners, it may sell
the rights,

                                      -16-
<PAGE>

warrants or other instruments in proportion to the number of Restricted American
Depositary Shares held by the Owners to whom it has determined it may not
lawfully or feasibly make such rights available, and allocate the net proceeds
of such sales (net of the fees and expenses of the Depositary as provided in
Section 5.09 and all taxes and governmental charges payable in connection with
such rights and subject to the terms and conditions of this Restricted Deposit
Agreement) for the account of such Owners otherwise entitled to such rights,
warrants or other instruments, upon an averaged or other practical basis without
regard to any distinctions among such Owners because of exchange restrictions or
the date of delivery of any Receipt or otherwise.

          The Depositary will not offer rights to Owners unless both the rights
and the securities to which such rights relate are either exempt from
registration under the Securities Act with respect to a distribution to all
Owners or are registered under the provisions of such Act; provided, that
                                                           --------
nothing in this Restricted Deposit Agreement shall create, any obligation on the
part of the Company to file a registration statement with respect to such rights
or underlying securities or to endeavor to have such a registration statement
declared effective.  If an Owner of Receipts requests the distribution of
warrants or other instruments, notwithstanding that there has been no such
registration under such Act, the Depositary shall not effect such distribution
unless it has received an opinion from recognized counsel in the United States
for the Company upon which the Depositary may rely that such distribution to
such Owner is exempt from such registration.

          The Depositary shall not be responsible for any failure to determine
that it may be lawful or feasible to make such rights available to Owners in
general or any Owner in particular.

          SECTION 4.05.  Conversion of Foreign Currency.  Whenever the
                         ------------------------------
Depositary or the Custodian shall receive foreign currency, by way of dividends
or other distributions or the net proceeds from the sale of securities, property
or rights, and if at the time of the receipt thereof the foreign currency so
received can in the judgment of the Depositary be converted on a reasonable
basis into Dollars and the resulting Dollars transferred to the United States,
the Depositary shall convert or cause to be converted, by sale or in any other
manner that it may determine, such foreign currency into Dollars, and such
Dollars shall be distributed to the Owners entitled thereto or, if the
Depositary shall have distributed any warrants or other instruments which
entitle the holders thereof to such Dollars, then to the holders of such
warrants and/or instruments upon surrender thereof for cancellation.  Such
distribution may be made upon an averaged or other practicable basis without
regard to any distinctions among Owners on account of exchange restrictions, the
date of delivery of any Receipt or otherwise and shall be net of any expenses of
conversion into Dollars incurred by the Depositary as provided in Section 5.09.

                                      -17-
<PAGE>

          If such conversion or distribution can be effected only with the
approval or license of any government or agency thereof, the Depositary shall
file such application for approval or license, if any, as it may deem desirable.

          If at any time the Depositary shall determine that in its judgment any
foreign currency received by the Depositary or the Custodian is not convertible
on a reasonable basis into Dollars transferable to the United States, or if any
approval or license of any government or agency thereof which is required for
such conversion is denied or in the opinion of the Depositary is not obtainable,
or if any such approval or license is not obtained within a reasonable period as
determined by the Depositary, the Depositary may distribute the foreign currency
(or an appropriate document evidencing the right to receive such foreign
currency) received by the Depositary to, or in its discretion may hold such
foreign currency uninvested and without liability for interest thereon for the
respective accounts of, the Owners entitled to receive the same.

          If any such conversion of foreign currency, in whole or in part,
cannot be effected for distribution to some of the Owners entitled thereto, the
Depositary may in its discretion make such conversion and distribution in
Dollars to the extent permissible to the Owners entitled thereto and may
distribute the balance of the foreign currency received by the Depositary to, or
hold such balance uninvested and without liability for interest thereon for the
respective accounts of, the Owners entitled thereto.

          SECTION 4.06.  Fixing of Record Date.  Whenever any cash dividend or
                         ---------------------
other cash distribution shall become payable or any distribution other than cash
shall be made, or whenever rights shall be issued with respect to the Deposited
Securities, or whenever the Depositary shall receive notice of any meeting of
holders of Shares or other Deposited Securities, or whenever for any reason the
Depositary causes a change in the number of Shares that are represented by each
Restricted American Depositary Share, or whenever the Depositary shall find it
necessary or convenient, the Depositary shall fix a record date, which shall be
the record date, if any, established by the Company for such purpose or, if
different, as close thereto as practicable, (a) for the determination of the
Owners who shall be (i) entitled to receive such dividend, distribution or
rights or the net proceeds of the sale thereof or (ii) entitled to give
instructions for the exercise of voting rights at any such meeting, or (b) on or
after which each Restricted American Depositary Share will represent the changed
number of Shares.  Subject to the provisions of Sections 4.01 through 4.05 and
to the other terms and conditions of this Restricted Deposit Agreement, the
Owners on such record date shall be entitled, as the case may be, to receive the
amount distributable by the Depositary with respect to such dividend or other
distribution or such rights or the net proceeds of sale thereof in proportion to
the number of Restricted American Depositary Shares held by them respectively
and to give voting instructions and to act in respect of any other such matter.

          SECTION 4.07.  Voting of Deposited Securities.  Upon receipt of notice
                         ------------------------------
of any meeting of holders of Shares or other Deposited Securities, if requested
in writing by the Company, the Depositary shall, as soon as practicable
thereafter, mail to the Owners a notice, the form of which notice shall be in
the sole discretion of the Depositary, which shall contain (a) all of the
information contained in such notice of meeting received by the Depositary from
the Company, (b) a statement that the Owners as of the close of business on a
specified record date will be entitled, subject to any applicable provision of
Irish law and of the Memorandum and Articles of Association of the Company, to
instruct the Depositary as to the exercise of the voting rights, if any,
pertaining to the amount of Shares or other Deposited Securities represented by
their respective Restricted American Depositary Shares, (c) a statement that
Owners who instruct the Depositary as to the exercise of their voting rights
will be deemed to have instructed the Depositary or its authorized
representative to call for a poll with respect to each matter for which such
instructions are given, subject to any applicable provisions of Irish law and of
the Memorandum and Articles of Association of the Company and (d) if applicable,
a statement as to the manner in which such instructions may be given, including
an express indication that instructions may be given or deemed given in
accordance with the last sentence of this paragraph if no instruction is
received, to the Depositary to give a discretionary proxy to a person designated
by the Company.  Upon the written request of an Owner on such record date,
received on or before the date established by the Depositary for such purpose,
the Depositary shall endeavor, in so far as practicable, to vote or cause to be
voted the amount of Shares or other Deposited Securities represented by the
American Depositary Shares evidenced by such Receipt in accordance with the
instructions set forth in such request.  Accordingly, pursuant to the Company's
Memorandum and Articles of Association and applicable Irish law, the Depositary
will cause its authorized representative to attend each meeting of holders of
Shares and call for a poll as instructed in accordance with clause (c) above for
the purpose of effecting such vote.  The Depositary shall not vote or attempt to
exercise the right to vote that attaches to the Shares or other Deposited
Securities, other than in accordance with such instructions or deemed
instructions.  If no instructions are received by the Depositary from any Owner
with respect to any of the Deposited Securities represented by the American
Depositary Shares evidenced by such Owner's Receipts on or before the date
established by the Depositary for such purpose, the Depositary will deem such
Owner to have instructed the Depositary to give a discretionary proxy to a
person designated by the Company with respect to such Deposited Securities and
the Depositary will give a discretionary proxy to a person designated by the
Company to vote such Deposited Securities; provided, that no such instructions
                                           --------
will be deemed given and no such discretionary proxy will be given when the
Company notifies the Depositary (and the Company agrees to provide such notice
as promptly as practicable in writing) that the matter to be voted upon is one
of the following:

                                      -19-
<PAGE>

          1.  is a matter not submitted to shareholders by means of a proxy
          statement comparable to that specified in Schedule 14-A of the
          Commission;

          2.  is the subject of a counter-solicitation, or is part of a proposal
          made by a shareholder which is being opposed by management (i.e., a
                                                                      - -
          contest);

          3.  relates to a merger or consolidation (except when the Company's
          proposal is to merge with its own wholly-owned subsidiary, provided
          its shareholders dissenting thereto do not have rights of appraisal);

          4.  involves right of appraisal;

          5.  authorizes mortgaging of property;

          6.  authorizes or creates indebtedness or increases the authorized
          amount of indebtedness;

          7.  authorizes or creates preferred shares or increases the authorized
          amount of existing preferred shares;

          8.  alters the terms or conditions of any shares of the Company's
          stock then outstanding or existing indebtedness;

          9.  involves waiver or modification of preemptive rights (except when
          the Company's proposal is to waive such rights with respect to
          ordinary shares being offered pursuant to stock option or purchase
          plans involving the additional issuance of not more than 5% of the
          Company's outstanding ordinary shares (see Item 12 below));

          10. alters voting provisions or the proportionate voting power of a
          class of shares, or the number of its votes per share (except where
          cumulative voting provisions govern the number of votes per share for
          election of directors and the Company's proposal involves a change in
          the number of its directors by not more than 10% or not more than
          one);

          11. changes existing quorum requirements with respect to shareholder
          meetings;

          ordinary shares, to directors, officers, or employees in an amount
          which exceeds 5% of the total amount of the class outstanding (when no
          plan is

          amended to extend its duration, the Company shall factor into the
          calculation the number of ordinary shares that remain available for
          issuance, the number of ordinary shares subject to outstanding options
          and any ordinary shares being added; should there be more than one
          plan being considered at the same meeting, all ordinary shares are
          aggregated);

          13.  authorizes

               (a) a new profit-sharing or special remuneration plan, or a new
               retirement plan, the annual cost of which will amount to more
               than 10% of average annual income before taxes for the preceding
               five years; or

               (b) the amendment of an existing plan which would bring its costs
               above 10% of such average annual income before taxes (should
               there be more than one plan being considered at the same meeting,
               all costs are aggregated; exceptions may be made in cases of (a)
               retirement plans based on agreement or negotiations with labor
               unions (or which have been or are to be approved by such unions);
               and (b) any related retirement plan for benefit of non-union
               employees having terms substantially equivalent to the terms of
               such union-negotiated plan, which is submitted for action of
               stockholders concurrently with such union-negotiated plan);

          14.  changes the purposes or powers of the Company to an extent which
          would permit it to change a materially different line of business and
          it is the Company's stated intention to make such a change;

          15.  authorizes the acquisition of property, assets, or a company,
          where the consideration to be given has a fair value of 20% or more of
          the market value of the previously outstanding shares;

          16.  authorizes the sale or other disposition of assets or earning
          power of 20% or more of those existing prior to the transaction;

          17.  authorizes a transaction not in the ordinary course of business
          in which an officer, director or substantial security holder has a
          direct or indirect interest;

          18.  reduces earned surplus by 51% or more, or reduces earned surplus
          to an amount less than the aggregate of three years' ordinary share
          dividends computed at the current dividend rate.

          SECTION 4.08.  Changes Affecting Deposited Securities.  In
                         --------------------------------------
circumstances where the provisions of Section 4.03 do not apply, upon any change
in nominal value, change in par value, split-up, consolidation or any other
reclassification of Deposited Securities, or upon any recapitalization,
reorganization, merger or consolidation or sale of assets affecting the Company
or to which it is a party, any securities which shall be received by the
Depositary or a Custodian in exchange for or in conversion of or in respect of
Deposited Securities, shall be treated as new Deposited Securities under this
Restricted Deposit Agreement, and Restricted American Depositary Shares shall
thenceforth represent, in addition to the existing Deposited Securities, the
right to receive the new Deposited Securities so received in exchange or
conversion, unless additional Receipts are delivered pursuant to the following
sentence.  In any such case the Depositary may execute and deliver additional
Receipts as in the case of a dividend in Shares, or call for the surrender of
outstanding Receipts to be exchanged for new Receipts specifically describing
such new Deposited Securities.

          SECTION 4.09.  Reports.  The Depositary shall make available for
                         -------
inspection by Owners at its Corporate Trust Office any reports and
communications, including any proxy soliciting material, received from the
Company which are both (a) received by the Depositary as the holder of the
Deposited Securities and (b) made generally available to the holders of such
Deposited Securities by the Company.  The Depositary shall also send to the
Owners copies of such reports when furnished by the Company pursuant to Section
5.06. Any such reports and communications, including any such proxy soliciting
material, furnished to the Depositary by the Company shall be furnished in
English, to the extent such materials are required to be translated into English
pursuant to any regulations of the Commission.

          SECTION 4.10.  Lists of Owners.  Promptly upon request by the Company,
                         ---------------
the Depositary shall, at the expense of the Company, furnish to it a list, as of
a recent date, of the names, addresses and holdings of Restricted American
Depositary Shares by all persons in whose names Receipts are registered on the
books of the Depositary.

          SECTION 4.11.  Withholding.  In the event that the Depositary
                         -----------
determines that any distribution in property (including Shares and rights to
subscribe therefor) is subject to any tax or other governmental charge which the
Depositary is obligated to withhold, the Depositary may by public or private
sale dispose of all or a portion of such property (including Shares and rights
to subscribe therefor) in such amounts and in such manner as the Depositary
deems necessary and practicable to pay such taxes or charges and the Depositary
shall distribute the net proceeds of any such sale after deduction of such taxes
or charges to the Owners entitled thereto in proportion to the number of
Restricted American Depositary Shares held by them respectively.

                THE DEPOSITARY, THE CUSTODIANS AND THE COMPANY

          SECTION 5.01.  Maintenance of Office and Transfer Books by the
                         -----------------------------------------------
Depositary.  Until termination of this Restricted Deposit Agreement in
- ----------
accordance with its terms, the Depositary shall maintain in the Borough of
Manhattan, The City of New York, facilities for the execution and delivery,
registration, registration of transfers and surrender of Receipts in accordance
with the provisions of this Restricted Deposit Agreement.

          The Depositary shall keep books, at its Corporate Trust Office, for
the registration of Receipts and transfers of Receipts which at all reasonable
times shall be open for inspection by the Owners, provided that such inspection
shall not be for the purpose of communicating with Owners in the interest of a
business or object other than the business of the Company or a matter related to
this Restricted Deposit Agreement or the Receipts.

          The Depositary may close the transfer books, at any time or from time
to time, when deemed expedient by it in connection with the performance of its
duties hereunder.

          If any Receipts or the Restricted American Depositary Shares evidenced
thereby are listed on one or more stock exchanges in the United States, the
Depositary shall act as Registrar or appoint a Registrar or one or more co-
registrars for registry of such Receipts in accordance with any requirements of
such exchange or exchanges.

          SECTION 5.02.  Prevention or Delay in Performance by the Depositary or
                         -------------------------------------------------------
the Company.  Neither the Depositary nor the Company nor any of their respective
- -----------
directors, employees, agents or affiliates shall incur any liability to any
Owner or Beneficial Owner of any Receipt, if by reason of any provision of any
present or future law or regulation of the United States or any other country,
or of any governmental or regulatory authority or stock exchange, or by reason
of any provision, present or future, of the Memorandum and Articles of
Association of the Company, or by reason of any provision of any securities
issued or distributed by the Company, or any offering or distribution thereof,
or by reason of any act of God or war or other circumstances beyond its control,
the Depositary or the Company shall be prevented, delayed or forbidden from, or
be subject to any civil or criminal penalty on account of, doing or performing
any act or thing which by the terms of this Restricted Deposit Agreement or
Deposited Securities it is provided shall be done or performed; nor shall the
Depositary or the Company or any of their respective directors, employees,
agents or affiliates incur any liability to any

                                      -23-
<PAGE>

Owner or Beneficial Owner of any Receipt by reason of any nonperformance or
delay, caused as aforesaid, in the performance of any act or thing which by the
terms of this Restricted Deposit Agreement it is provided shall or may be done
or performed, or by reason of any exercise of, or failure to exercise, any
discretion provided for in this Restricted Deposit Agreement. Where, by the
terms of a distribution pursuant to Section 4.01, 4.02, or 4.03 of the
Restricted Deposit Agreement, or an offering or distribution pursuant to Section
4.04 of the Restricted Deposit Agreement, or for any other reason, such
distribution or offering may not be made available to Owners, and the Depositary
may not dispose of such distribution or offering on behalf of such Owners and
make the net proceeds available to such Owners, then the Depositary shall not
make such distribution or offering, and shall allow any rights, if applicable,
to lapse.

          SECTION 5.03.  Obligations of the Depositary, the Custodian and the
                         ----------------------------------------------------
Company.  The Company assumes no obligation nor shall it be subject to any
- -------
liability under this Restricted Deposit Agreement to Owners or Beneficial
Owners, except that it agrees to perform its obligations specifically set forth
in this Restricted Deposit Agreement without negligence or bad faith.

          The Depositary assumes no obligation nor shall it be subject to any
liability under this Restricted Deposit Agreement to any Owner or Beneficial
Owner (including, without limitation, liability with respect to the validity or
worth of the Deposited Securities), except that it agrees to perform its
obligations specifically set forth in this Restricted Deposit Agreement without
negligence or bad faith.

          Neither the Depositary nor the Company shall be under any obligation
to appear in, prosecute or defend any action, suit or other proceeding in
respect of any Deposited Securities or in respect of the Receipts, which in its
opinion may involve it in expense or liability, unless indemnity satisfactory to
it against all expense and liability shall be furnished as often as may be
required, and the Custodian shall not be under any obligation whatsoever with
respect to such proceedings, the responsibility of the Custodian being solely to
the Depositary.

          Neither the Depositary nor the Company shall be liable for any action
or nonaction by it in reliance upon the advice of or information from legal
counsel, accountants, any person presenting Shares for deposit, any Owner or any
other person believed by it in good faith to be competent to give such advice or
information.

          The Depositary shall not be liable for any acts or omissions made by a
successor depositary whether in connection with a previous act or omission of
the Depositary or in  connection with any matter arising wholly after the
removal or resignation of the Depositary, provided that in connection with the
issue out of which

                                      -24-
<PAGE>

such potential liability arises the Depositary performed its obligations without
negligence or bad faith while it acted as Depositary.

          The Depositary shall not be responsible for any failure to carry out
any instructions to vote any of the Deposited Securities, or for the manner in
which any such vote is cast or the effect of any such vote, provided that any
such action or nonaction is in good faith.

          No disclaimer of liability under the Securities Act is intended by any
provision of this Restricted Deposit Agreement.

          SECTION 5.04.  Resignation and Removal of the Depositary.  The
                         -----------------------------------------
Depositary may at any time resign as Depositary hereunder by written notice of
its election so to do delivered to the Company, such resignation to take effect
upon the appointment of a successor depositary and its acceptance of such
appointment as hereinafter provided.

          The Depositary may at any time be removed by the Company by written
notice of such removal effective upon the appointment of a successor depositary
and its acceptance of such appointment as hereinafter provided.

          In case at any time the Depositary acting hereunder shall resign or be
removed, the Company shall use its best efforts to appoint a successor
depositary, which shall be a bank or trust company having an office in the
Borough of Manhattan, The City of New York.  Every successor depositary shall
execute and deliver to its predecessor and to the Company an instrument in
writing accepting its appointment hereunder, and thereupon such successor
depositary, without any further act or deed, shall become fully vested with all
the rights, powers, duties and obligations of its predecessor; but such
predecessor, nevertheless, upon payment of all sums due it and on the written
request of the Company shall execute and deliver an instrument transferring to
such successor all rights and powers of such predecessor hereunder, shall duly
assign, transfer and deliver all right, title and interest in the Deposited
Securities to such successor, and shall deliver to such successor a list of the
Owners of all outstanding Receipts.  Any such successor depositary shall
promptly mail notice of its appointment to the Owners.

          Any corporation into or with which the Depositary may be merged or
consolidated shall be the successor of the Depositary without the execution or
filing of any document or any further act.

          SECTION 5.05.  The Custodians.  The Custodian shall be subject at all
                         --------------
times and in all respects to the directions of the Depositary and shall be
responsible solely to it.  Any Custodian may resign and be discharged from its
duties hereunder by written

                                      -25-
<PAGE>

notice of such resignation delivered to the Depositary at least 30 days prior to
the date on which such resignation is to become effective. If upon such
resignation there shall be no Custodian acting hereunder, the Depositary shall,
promptly after receiving such notice, appoint a substitute custodian or
custodians, each of which shall thereafter be a Custodian hereunder. Whenever
the Depositary in its discretion determines that it is in the best interest of
the Owners to do so, it may appoint a substitute or additional custodian or
custodians, each of which shall thereafter be one of the Custodians hereunder.
Upon demand of the Depositary any Custodian shall deliver such of the Deposited
Securities held by it as are requested of it to any other Custodian or such
substitute or additional custodian or custodians. Each such substitute or
additional custodian shall deliver to the Depositary, forthwith upon its
appointment, an acceptance of such appointment satisfactory in form and
substance to the Depositary.

          Upon the appointment of any successor depositary hereunder, each
Custodian then acting hereunder shall forthwith become, without any further act
or writing, the agent hereunder of such successor depositary and the appointment
of such successor depositary shall in no way impair the authority of each
Custodian hereunder; but the successor depositary so appointed shall,
nevertheless, on the written request of any Custodian, execute and deliver to
such Custodian all such instruments as may be proper to give to such Custodian
full and complete power and authority as agent hereunder of such successor
depositary.

          SECTION 5.06.  Notices and Reports.  On or before the first date on
                         -------------------
which the Company gives notice, by publication or otherwise, of any meeting of
holders of Shares or other Deposited Securities, or of any adjourned meeting of
such holders, or of the taking of any action in respect of any cash or other
distributions or the offering of any rights, the Company agrees to transmit to
the Depositary and the Custodian a copy of the notice thereof in the form given
or to be given to holders of Shares or other Deposited Securities.

          The Company will arrange for the translation into English, if not
already in English, to the extent required pursuant to any regulations of the
Commission, and the prompt transmittal by the Company to the Depositary and the

          SECTION 5.07.  Distribution of Additional Shares, Rights, etc.  The
                         -----------------------------------------------
Company agrees that in the event of any issuance or distribution of (1)
additional Shares, (2) rights to subscribe for Shares, (3) securities
convertible into Shares, or (4) rights to subscribe for such securities (each a
"Distribution"), the Company will promptly furnish to the Depositary a written
opinion from U.S. counsel for the Company, which counsel shall be satisfactory
to the Depositary, stating whether or not the Distribution requires a
Registration Statement under the Securities Act to be in effect prior to making
such Distribution available to Owners entitled thereto.  If in the opinion of
such counsel a Registration Statement is required, such counsel shall furnish to
the Depositary a written opinion as to whether or not there is a Registration
Statement in effect which will cover such Distribution.

          The Company agrees with the Depositary that neither the Company nor
any person controlled by, controlling or under common control with the Company
will at any time deposit any Shares, either originally issued or previously
issued and reacquired by the Company or any such affiliate, unless a
Registration Statement is in effect as to such Shares under the Securities Act.

          SECTION 5.08.  Indemnification.  The Company agrees to indemnify the
                         ---------------
Depositary, its directors, employees, agents and affiliates and any Custodian
against, and hold each of them harmless from, any liability or expense
(including, but not limited to, the fees and expenses of counsel) which may
arise out of acts performed or omitted, in accordance with the provisions of
this Restricted Deposit Agreement and of the Receipts, as the same may be
amended, modified or supplemented from time to time, (i) by either the
Depositary or a Custodian or their respective directors, employees, agents and
affiliates, except for any liability or expense arising out of the negligence or
bad faith of either of them, or (ii) by the Company or any of its directors,
employees, agents and affiliates.

          The Depositary agrees to indemnify the Company, its directors,
employees, agents and affiliates and hold them harmless from any liability or
expense which may arise out of acts performed or omitted by the Depositary or
its Custodian or their respective directors, employees, agents and affiliates
due to their negligence or bad faith.

          SECTION 5.09.  Charges of Depositary.  The Company agrees to pay the
                         ---------------------
fees, reasonable expenses and out-of-pocket charges of the Depositary and those
of any Registrar only in accordance with agreements in writing entered into
between the Depositary and the Company from time to time.  The Depositary shall
present its statement for such charges and expenses to the Company once every
three months.  The charges and expenses of the Custodian are for the sole
account of the Depositary.

          SECTION 6.01.  Amendment.  The form of the Receipts and any provisions
                         ---------
of this Restricted Deposit Agreement may at any time and from time to time be
amended by agreement between the Company and the Depositary without the consent
of Owners or Beneficial Owners of Receipts in any respect which they may deem
necessary or desirable, including, without limitation, amendments agreed upon
pursuant to Section 2.09(b) hereof.  Any amendment which shall impose or
increase any fees or charges (other than taxes and other governmental charges,
registration fees, cable, telex or facsimile transmission costs, delivery costs
or other such expenses), or which shall otherwise prejudice any substantial
existing right of Owners, shall, however, not become effective as to outstanding
Receipts until the expiration of thirty days after notice of such amendment
shall have been given to the Owners of outstanding Receipts.  Every Owner, at
the time any amendment so becomes effective, shall be deemed, by continuing to
hold such Receipt, to consent and agree to such amendment and to be bound by the
Restricted Deposit Agreement as amended thereby.  In no event shall any
amendment impair the right of the Owner of any Receipt to surrender such Receipt
and receive therefor the Deposited Securities represented thereby, except in
order to comply with mandatory provisions of applicable law.

          SECTION 6.02.  Termination.  The Depositary shall, at any time at the
                         -----------
direction of the Company, terminate this Restricted Deposit Agreement by mailing
notice of such termination to the Owners of all Receipts then outstanding at
least 90 days prior to the date fixed in such notice for such termination.  The
Depositary may likewise terminate this Restricted Deposit Agreement by mailing
notice of such termination to the Company and the Owners of all Receipts then
outstanding, if at any time 90 days shall have expired after the Depositary
shall have delivered to the Company a written notice of its election to resign
and a successor depositary shall not have been appointed and accepted its
appointment as provided in Section 5.04.  On and after the date of termination,
the Owner of a Receipt will, upon (a) surrender of such Receipt at the Corporate
Trust Office of the Depositary, (b) payment of the fee of the Depositary for the
surrender of Receipts referred to in Section 2.05, and (c) payment of any
applicable taxes or governmental charges, be entitled to delivery, to him or
upon his order, of the amount of Deposited Securities represented by the
American Depositary Shares evidenced by such Receipt.  If any Receipts shall
remain outstanding after the date of termination, the Depositary thereafter
shall discontinue the registration of transfers of Receipts, shall suspend the
distribution of dividends to the Owners thereof, and shall not give any further
notices or perform any further acts under this Restricted Deposit Agreement,
except that the Depositary shall continue to collect dividends and other
distributions pertaining to Deposited Securities, shall sell rights and other
property as provided in this Restricted Deposit Agreement, and shall continue to
deliver Deposited Securities, together with any dividends or other distributions
received with respect thereto and the net proceeds of the sale of any rights or
other property, in exchange for Receipts surrendered to the Depositary (after
deducting, in each case, the fee of the Depositary for the surrender of a

                                     -29-
<PAGE>

Receipt, any expenses for the account of the Owner of such Receipt in accordance
with the terms and conditions of this Restricted Deposit Agreement, and any
applicable taxes or governmental charges).  At any time after the expiration of
one year from the date of termination, the Depositary may sell the Deposited
Securities then held hereunder and may thereafter hold uninvested the net
proceeds of any such sale, together with any other cash then held by it
hereunder, unsegregated and without liability for interest, for the pro rata
benefit of the Owners of Receipts which have not theretofore been surrendered,
such Owners thereupon becoming general creditors of the Depositary with respect
to such net proceeds. After making such sale, the Depositary shall be discharged
from all obligations under this Restricted Deposit Agreement, except to account
for such net proceeds and other cash (after deducting, in each case, the fee of
the Depositary for the surrender of a Receipt, any expenses for the account of
the Owner of such Receipt in accordance with the terms and conditions of this
Restricted Deposit Agreement, and any applicable taxes or governmental charges).
Upon the termination of this Restricted Deposit Agreement, the Company shall be
discharged from all obligations under this Restricted Deposit Agreement except
for its obligations to the Depositary under Sections 5.08 and 5.09 hereof.

                  Certification and Agreement of Acquirors of
                  Receipts Upon Deposit of Shares Pursuant to
             Section 2.02 of the Restricted Deposit Agreement (B)


          We refer to the Restricted Deposit Agreement (B), dated as of June 8,
1999, (the "Restricted Deposit Agreement"), among CBT GROUP PLC (the "Company"),
THE BANK OF NEW YORK, as Depositary, and Owners and Beneficial Owners of
Restricted American Depositary Receipts (the "Receipts") issued thereunder.
Capitalized terms used but not defined herein shall have the meanings given them

          1.  This certification and agreement is furnished in connection with
the deposit of Shares and issuance of Restricted American Depositary Shares to
be evidenced by one or more Receipts pursuant to Section 2.02 of the Restricted
Deposit Agreement.

          2.   We represent that, if the Shares being deposited were not
registered under the Securities Act of 1933, as amended (the "Act"), we acquired
the Shares in a transaction exempt from registration under the Act.

          3.  We acknowledge that the offer and sale of the Receipts, the
Restricted American Depositary Shares evidenced thereby and the Shares which may
be received upon surrender of Receipts or cancellation of American Depositary
Shares have not been and will not be registered under the Securities Act of
1933, as amended (the "Act") and may not be offered, sold, pledged or otherwise
transferred unless registered under the Act or unless an exemption from
registration is available.

          4.  We acknowledge that each Receipt (i) will be in physical form and
legended, (ii) will be registered in the name of the beneficial owner furnishing
this Deposit Certificate, (iii) will not be eligible for acceptance in any book-
entry settlement system, and (iv) may only be transferred in accordance with

          5.  We acknowledge that the Receipts, the Restricted American
Depositary Shares evidenced thereby, and the Shares which may be received upon
surrender of Receipts or cancellation of American Depositary Shares may be
subject to different and less favorable restrictions on transfer than those
applicable to the Shares hereby being deposited, including, without limitation,
the unavailability of transfer based on the satisfaction of a holding period
pursuant to paragraphs (d) or (k) of Rule 144 under the Securities Act.

          6.   We certify that either:

[_]  C.   the Shares have been or are subject to restrictions on transfer by us
          pursuant to the holding period requirements of Rule 144(d) under the

          holding period; and we have attached an opinion of counsel
          satisfactory to the Depositary stating that after deposit of the
          Shares, all of the Receipts, the American Depositary Shares, and all
          other deposited Shares may after the deposit of our Shares still be

and at the time the Receipts are issued will be, the beneficial owner of the
Shares and of the Restricted American Depositary Shares evidenced by such
Receipt or Receipts and if the Shares were acquired in a transaction exempt from

United States (within the meaning of Regulation S under the Act) and acquired,
or have agreed to acquire and will have acquired, the Shares to be deposited
outside the United States (within the meaning of Regulation S).

          8.   We agree that the Receipts, the Restricted American Depositary
Shares evidenced thereby and the Shares represented thereby may not be offered,
sold, pledged or otherwise transferred except pursuant to an effective

Depositary Shares or in accordance with the transfer restrictions imposed by
paragraphs (c), (e), (f), (g) and, if applicable, (h) of Rule 144 under the Act,

                Certification and Agreement of Certain Persons
                       Transferring Receipts Pursuant to
                           Sections 2.01 and 2.04 of
                     the Restricted Deposit Agreement (B)


          We refer to the Restricted Deposit Agreement (B), dated as of June 8,
1999 (the "Restricted Deposit Agreement"), among CBT GROUP PLC (the "Company"),
THE BANK OF NEW YORK, as Depositary thereunder (the "Depositary"), and Owners
and Beneficial Owners of Restricted American Depositary Receipts (the
"Receipts") issued thereunder.  Capitalized terms used but not defined herein
shall have the meanings given them in the Restricted Deposit Agreement.

          1.  The undersigned Beneficial Owner is surrendering a Receipt or
Receipts in accordance with the terms of the Restricted Deposit Agreement for
the purpose of transferring its beneficial interest in Restricted American
Depositary Shares pursuant to Section 2.04 and 2.09 of the Restricted Deposit
Agreement.

          2.  The undersigned Beneficial Owner acknowledges that the Receipts,
the Restricted American Depositary Shares evidenced thereby and the ordinary
shares of the Company which may be received upon surrender of this Receipt or
cancellation of the Restricted American Depositary Shares have not been and will
not be registered under the Securities Act of 1933, as amended (the "Act") and
may not be offered, sold, pledged or otherwise transferred unless registered
under the Act or unless an exemption from registration is available.

          3.  The undersigned Beneficial Owner certifies that we have sold or
otherwise transferred, or agreed to sell or otherwise transfer, the Shares
pursuant to an effective registration statement registering the resale of the
Restricted American Depositary Shares or in accordance with paragraphs (c), (e),
(f), (g) and, if applicable, (h) of Rule 144 under the Act, without regard to
any termination of any such restriction by operation of paragraph (k) of Rule
144, in accordance with any applicable securities laws of any state of the
United States, and are surrendering a Receipt or Receipts for the purpose of
cancellation thereof. In connection therewith and as a condition precedent
thereto, we have delivered to the Depositary a written opinion of U.S. counsel
satisfactory to the Depositary.  The Depositary, subject to applicable law and
the terms and conditions of the Restricted Deposit Agreement, shall exchange
Receipts evidencing Restricted American Depositary Shares surrendered hereunder
in connection with a transfer pursuant to an effective registration statement
registering the resale of the Restricted American Depositary Shares or in
accordance with paragraphs (c), (e), (f), (g) and, if applicable, (h)


                                  Annex II-1
<PAGE>

of Rule 144 under the Act, for ADRs evidencing ADSs issued pursuant to the ADR
Agreement.

          4.  The undersigned Beneficial Owner certifies that we have no reason
to believe that the person to whom a beneficial interest in Restricted
Depositary Shares is hereby to be transferred is an affiliate of the Company,
within the meaning of Rule 144 under the Securities Act.

          This certification and agreement may be signed in counterparts.

                           Very truly,

          Upon surrender at the Corporate Trust Office of the Depositary of this
Receipt, and upon payment of the fee of the Depositary provided in this Receipt,
and subject to the terms and conditions of the Restricted Deposit Agreement, the
Owner hereof is entitled to delivery, to him or upon his order, of the Deposited

for which this Receipt is issued.  Delivery of such Deposited Securities may be
made by the delivery of (a) certificates in the name of the Owner hereof or as
ordered by him or certificates properly endorsed or accompanied by proper
instruments of transfer and (b) any other securities, property and cash to which
such Owner is then entitled in respect of this Receipt.  Such delivery will be
made at the option of the Owner hereof, either at the office of the Custodian or
at the Corporate Trust Office of the Depositary, provided that the forwarding of
certificates for Shares or other Deposited Securities for such delivery at the
Corporate Trust Office of the Depositary shall be at the risk and expense of the
Owner hereof.  Notwithstanding anything to the contrary in the Restricted
Deposit Agreement, no Deposited Securities may be withdrawn upon the surrender
of this Receipt unless the Depositary shall have received (a) a written opinion
of U.S. counsel satisfactory to the Depositary in connection with a withdrawal
in accordance with Rule 144 or Rule 145 under the Securities Act, and (b) a duly
executed and completed written certificate and agreement, in substantially the
form annexed to the Restricted Deposit Agreement as Annex III, by or on behalf
of the person surrendering such Receipt who after such withdrawal will be the
beneficial owner of such Deposited Securities; provided, however, that no such
                                               --------  -------
certificate and agreement shall be required for a withdrawal in connection with
a transfer pursuant to an effective registration statement registering the
resale of the Restricted American Depositary Shares or in accordance with
paragraphs (c), (e), (f), (g) and, if applicable, (h) of Rule 144 under the
Securities Act, without regard to any termination of certain restrictions by
operation of paragraph (k) of that Rule, in which case the terms and provisions
of Section 2.09 of the Restricted Deposit Agreement and Article 4 hereof shall
apply.

          3.  TRANSFERS, SPLIT-UPS, AND COMBINATIONS OF RECEIPTS.

          Upon receipt by the Depositary of (a) a written opinion of U.S.
counsel satisfactory to the Depositary in connection with a transfer pursuant to
an effective registration statement registering the resale of the Restricted
American Depositary Shares or in accordance with paragraphs (c), (e), (f), (g)
and, if applicable, (h) of Rule 144 under

                                      A-4
<PAGE>

the Securities Act, pursuant to either Rule 144 or Rule 145 under the Securities
Act, without regard to any termination of certain restrictions by operation of
paragraph (k) of that Rule, and (b) a duly executed and completed written
certification and agreement ("Transfer Certificate"), in substantially the form
attached as Annex II to the Restricted Deposit Agreement, upon surrender of this
Receipt properly endorsed for transfer or accompanied by proper instruments of
transfer and funds sufficient to pay any applicable transfer taxes and the
expenses of the Depositary as provided in Section 5.09 of the Restricted Deposit
Agreement and upon compliance with such regulations, if any, as the Depositary
may establish for such purpose the Depositary shall effect an exchange of this
Receipt in accordance with the terms and conditions of the Restricted Deposit
Agreement. This Receipt may be split into other such Receipts, or may be
combined with other such Receipts into one Receipt, evidencing the same
aggregate number of Restricted American Depositary Shares as the Receipt or
Receipts surrendered. As a condition precedent to the execution and delivery,
registration of transfer, split-up, combination, or surrender of any Receipt or
withdrawal of any Deposited Securities, the Depositary, the Custodian, or
Registrar may require payment from the depositor of the Shares or the presenter
of the Receipt of a sum sufficient to reimburse it for any tax or other
governmental charge and any stock transfer or registration fee with respect
thereto (including any such tax or charge and fee with respect to Shares being
deposited or withdrawn) and payment of any applicable fees as provided in this
Receipt, may require the production of proof satisfactory to it as to the
identity and genuineness of any signature and may also require compliance with
any regulations the Depositary may establish consistent with the provisions of
the Restricted Deposit Agreement or this Receipt, including, without limitation,
this Article 3.

          The representations and warranties included within the Transfer
Certificate in the form of Annex II to be delivered shall survive such transfer,
surrender and withdrawal, split-up or combination of the Shares and Receipts.

          The delivery of Receipts against deposit of Shares generally or
against deposit of particular Shares may be suspended, or the transfer of
Receipts in particular instances may be refused, or the registration of transfer
of outstanding Receipts generally may be suspended, during any period when the
transfer books of the Depositary are closed, or if any such action is deemed
necessary or advisable by the Depositary or the Company at any time or from time
to time because of any requirement of law or of any government or governmental
body or commission, or under any provision of the Restricted Deposit Agreement
or this Receipt, or for any other reason.

          4.  EXCHANGE OF RESTRICTED AMERICAN DEPOSITARY SHARES FOR ADSs.

          Subject to applicable law and the terms and conditions of the
Restricted Deposit Agreement and this Receipt, upon receipt by the Depositary of
a written opinion

<PAGE>

of U.S. counsel satisfactory to the Depositary and a duly executed and completed
Transfer Certificate substantially in the form annexed to the Restricted Deposit
Agreement, Restricted American Depositary Shares sold or otherwise transferred
pursuant to an effective registration statement registering the resale of the
Restricted American Depositary Shares or in accordance with paragraphs (c), (e),
(f), (g) and, if applicable (h) of Rule 144 under the Securities Act, pursuant
to either Rule 144 or Rule 145 under the Securities Act, without regard to any
termination of certain restrictions by operation of paragraph (k) of that Rule,
shall be exchanged for ADSs issued pursuant to the ADR Deposit Agreement. The
transferees of the interests of Owners and Beneficial Owners of Receipts under
the Restricted Deposit Agreement shall thereafter be owners and beneficial
owners of ADRs issued pursuant to the ADR Deposit Agreement and shall have all
of the rights and obligations set forth under the ADR Deposit Agreement and the
ADRs. In connection with an Exchange, all Owners and Beneficial Owners of
Receipts issued under the Restricted Deposit Agreement shall be deemed to have
made the representations and warranties set forth in Section 3.03 of the ADR
Deposit Agreement. Each Owner and Beneficial Owner acknowledges and agrees that
there can be no assurance that applicable laws will permit the Depositary to
effect an Exchange as described herein and in the Restricted Deposit Agreement.

          5.  LIABILITY OF OWNER OR BENEFICIAL OWNER FOR TAXES.

          If any tax or other governmental charge shall become payable by the
Custodian or the Depositary with respect to any Receipt or any Deposited
Securities represented hereby, such tax or other governmental charge shall be
payable by the Owner or Beneficial Owner hereof to the Depositary.  The
Depositary may refuse to effect any transfer of this Receipt or any withdrawal
of Deposited Securities represented by Restricted American Depositary Shares
evidenced by such Receipt until such payment is made, and may withhold any
dividends or other distributions, or may sell for the account of the Owner or
Beneficial Owner hereof any part or all of the Deposited Securities represented
by the Restricted American Depositary Shares evidenced by this Receipt, and may
apply such dividends or other distributions or the proceeds of any such sale in
payment of such tax or other governmental charge and the Owner or Beneficial
Owner hereof shall remain liable for any deficiency.

          6.  WARRANTIES ON DEPOSIT OF SHARES.

          Every person depositing Shares under the Restricted Deposit Agreement
shall be deemed thereby to represent and warrant, in addition to such
representations and warranties as may be required pursuant to Section 2.02 of
the Restricted Deposit Agreement, that such Shares and each certificate therefor
are validly issued, fully paid, non-assessable, and free of any preemptive
rights of the holders of outstanding Shares and that the person making such
deposit is duly authorized so to do.  Such representations and warranties shall
survive the deposit of Shares and issuance of Receipts.

                                      A-6
<PAGE>

          7.  FILING PROOFS, CERTIFICATES, AND OTHER INFORMATION.

          Any person presenting Shares for deposit or any Owner or Beneficial
Owner of a Receipt may be required from time to time to file with the Depositary
or the Custodian such proof of citizenship or residence, exchange control
approval, or such information relating to the registration on the books of the
Company or the Foreign Registrar, if applicable, to execute such certificates
and to make such representations and warranties, as the Depositary may deem
necessary or proper.  The Depositary may withhold the delivery or registration
of transfer of any Receipt or the distribution of any dividend or sale or
distribution of rights or of the proceeds thereof or the delivery of any
Deposited Securities until such proof or other information is filed or such
certificates are executed or such representations and warranties made.  No Share
shall be accepted for deposit unless accompanied by evidence satisfactory to the
Depositary that any necessary approval has been granted by any governmental body
in The Republic of Ireland which is then performing the function of the
regulation of currency exchange.

          8.  CHARGES OF DEPOSITARY.

          The Company agrees to pay the fees, reasonable expenses and out-of-
pocket charges of the Depositary and those of any Registrar only in accordance
with agreements in writing entered into between the Depositary and the Company
from time to time.  The Depositary shall present its statement for such charges
and expenses to the Company once every three months.  The charges and expenses
of the Custodian are for the sole account of the Depositary.

          The following charges shall be incurred by any party depositing or
withdrawing Shares or by any party surrendering Receipts or to whom Receipts are
issued (including, without limitation, issuance pursuant to a stock dividend or

Receipts or Deposited Securities or a distribution of Receipts pursuant to
Section 4.03 of the Restricted Deposit Agreement), whichever applicable: (1)
taxes and other governmental charges, (2) such registration fees as may from
time to time be in effect for the registration of transfers of Shares generally
on the Share register of the Company or Foreign Registrar and applicable to
transfers of Shares to the name of the Depositary or its nominee or the
Custodian or its nominee on the making of deposits or withdrawals under the
terms of the Restricted Deposit Agreement, (3) such cable, telex and facsimile

<PAGE>

thereof) for any cash distribution made pursuant to Sections 4.01 through 4.04
of the Restricted Deposit Agreement and (7) a fee for the distribution of
securities pursuant to Section 4.02 of the Restricted Deposit Agreement, such
fee being in an amount equal to the fee for the execution and delivery of
Restricted American Depositary Shares referred to above which would have been
charged as a result of the deposit of such securities (for purposes of this
clause 7 treating all such securities as if they were Shares), but which
securities are instead distributed by the Depositary to Owners and (8) a fee not
in excess of $1.50 per certificate for a Receipt or Receipts for transfers made
pursuant to the terms of the Restricted Deposit Agreement.

          The Depositary, subject to Article 8 hereof, may own and deal in any

          9.   TITLE TO RECEIPTS.

          It is a condition of this Receipt and every successive Owner and
Beneficial Owner of this Receipt by accepting or holding the same consents and
agrees, that title to this Receipt when properly endorsed or accompanied by
proper instruments of transfer, including, without limitation, any
certifications and agreements and opinions of counsel as may be required
pursuant to the terms and conditions of certificates and opinions required under
the Restricted Deposit Agreement, is transferable by delivery with the same
effect as in the case of a negotiable instrument under the laws of New York;
provided, however, that the Depositary, notwithstanding any notice to the
- --------  -------
contrary, may treat the person in whose name this Receipt is registered on the
books of the Depositary as the absolute owner hereof for the purpose of
determining the person entitled to distribution of dividends or other
distributions or to any notice provided for in the Restricted Deposit Agreement
or for all other purposes.

          10.  VALIDITY OF RECEIPT.

          This Receipt shall not be entitled to any benefits under the

this Receipt shall have been executed by the Depositary by the manual signature
of a duly authorized signatory of the Depositary; provided, however that such
                                                  --------  -------
signature may be a facsimile if a Registrar for the Receipts shall have been

made generally available to

                                      A-8

the holders of such Deposited Securities by the Company. The Depositary will
also send to Owners of Receipts copies of such reports when furnished by the
Company pursuant to the Restricted Deposit Agreement. Any such reports and
communications, including any such proxy soliciting material, furnished to the
Depositary by the Company shall be furnished in English to the extent such
materials are required to be translated into English pursuant to any regulations
of the Commission.

          The Depositary will keep books, at its Corporate Trust Office, for the
registration of Receipts and transfers of Receipts which at all reasonable times
shall be open for inspection by the Owners of Receipts provided that such
inspection shall not be for the purpose of communicating with Owners of Receipts
in the interest of a business or object other than the business of the Company
or a matter related to the Restricted Deposit Agreement or the Receipts.

          12.  DIVIDENDS AND DISTRIBUTIONS.

          Whenever the Depositary receives any cash dividend or other cash
distribution on any Deposited Securities, the Depositary will, if at the time of
receipt thereof any amounts received in a foreign currency can in the judgment
of the Depositary be converted on a reasonable basis into United States dollars
transferable to the United States, and subject to the Restricted Deposit
Agreement, convert such dividend or distribution into dollars and will
distribute the amount thus received (net of the fees and expenses of the
Depositary as provided in Article 7 hereof and Section 5.09 of the Restricted
Deposit Agreement) to the Owners of Receipts entitled thereto; provided,
                                                               --------
however, that in the event that the Company or the Depositary is required to
- -------
withhold and does withhold from any cash dividend or other cash distribution in
respect of any Deposited Securities an amount on account of taxes, the amount
distributed to the Owners of the Receipts evidencing Restricted American
Depositary Shares representing such Deposited Securities shall be reduced
accordingly.

          Subject to the provisions of Section 4.11 and 5.09 of the Restricted
Deposit Agreement, whenever the Depositary receives any distribution other than
a distribution described in Section 4.01, 4.03 or 4.04 of the Restricted Deposit
Agreement, the Depositary will cause the securities or property received by it
to be distributed to the Owners entitled thereto, in any manner that the
Depositary may deem equitable and practicable for accomplishing such
distribution; provided, however, that if in the opinion of the Depositary such
              --------  -------
distribution cannot be made proportionately among the Owners of Receipts
entitled thereto, or if for any other reason the Depositary deems such
distribution not to be feasible, the Depositary may adopt such method as it may
deem equitable and practicable for the purpose of effecting such distribution,
including, but not limited to, the public or private sale of the securities or
property thus received, or any part thereof, and the net proceeds of any such
sale (net of the fees and expenses of the Depositary as provided in Article 7
hereof and Section 5.09 of the Restricted Deposit Agreement) will

                                      A-9
<PAGE>

be distributed by the Depositary to the Owners of Receipts entitled thereto all
in the manner and subject to the conditions described in Section 4.01 of the
Restricted Deposit Agreement.

          If any distribution consists of a dividend in, or free distribution
of, Shares, the Depositary may distribute to the Owners of outstanding Receipts
entitled thereto, additional Receipts evidencing an aggregate number of
Restricted American Depositary Shares representing the amount of Shares received
as such dividend or free distribution subject to the terms and conditions of the
Restricted Deposit Agreement with respect to the deposit of Shares and the
issuance of Restricted American Depositary Shares evidenced by Receipts,
including the withholding of any tax or other governmental charge as provided in
Section 4.11 of the Restricted Deposit Agreement and the payment of the fees and
expenses of the Depositary as provided in Article 7 hereof and Section 5.09 of
the Restricted Deposit Agreement.  The Depositary may withhold any such
distribution of Receipts under Section 4.03 of the Restricted Deposit Agreement
if it has not received satisfactory assurances from the Company that such
distribution does not require registration under the Securities Act or is exempt
from registration under the provisions of such Act.  In lieu of delivering
Receipts for fractional Restricted American Depositary Shares in any such case,
the Depositary will sell the amount of Shares represented by the aggregate of
such fractions and distribute the net proceeds, all in the manner and subject to
the conditions described in Section 4.01 of the Restricted Deposit Agreement.
If additional Receipts are not so distributed, each Restricted American
Depositary Share shall thenceforth also represent the additional Shares
distributed upon the Deposited Securities represented thereby.  Each beneficial
owner of Receipts or Shares so distributed shall be deemed to have acknowledged
that the Receipts or Shares have not been registered under the Securities Act
and to have agreed to comply with the restrictions on transfer set forth on the
face of this Receipt.

          In the event that the Depositary determines that any distribution in
property (including Shares and rights to subscribe therefor) is subject to any
tax or other governmental charge which the Depositary is obligated to withhold,
the Depositary may by public or private sale dispose of all or a portion of such
property (including Shares and rights to subscribe therefor) in such amounts and
in such manner as the Depositary deems necessary and practicable to pay any such
taxes or charges, and the Depositary shall distribute the net proceeds of any
such sale after deduction of such taxes or charges to the Owners of Receipts
entitled thereto.

          13.  RIGHTS.

          In the event that the Company shall offer or cause to be offered to
the holders of any Deposited Securities any rights to subscribe for additional
Shares or any rights of any other nature, the Depositary shall have discretion
as to the procedure to be followed in making such rights available to any Owners
or in disposing of such rights on

                                     A-10
<PAGE>

behalf of any Owners and making the net proceeds available to such Owners or, if
by the terms of such rights offering or for any other reason, the Depositary may
not either make such rights available to any Owners or dispose of such rights
and make the net proceeds available to such Owners, then the Depositary shall
allow the rights to lapse. If at the time of the offering of any rights the
Depositary determines in its discretion that it is lawful and feasible to make
such rights available to all or certain Owners but not to other Owners, the
Depositary may distribute to any Owner to whom it determines the distribution to
be lawful and feasible, in proportion to the number of Restricted American
Depositary Shares held by such Owner, warrants or other instruments therefor in
such form as it deems appropriate.

          In circumstances in which rights would otherwise not be distributed,
if an Owner of Receipts requests the distribution of warrants or other
instruments in order to exercise the rights allocable to the Restricted American
Depositary Shares of such Owner hereunder, the Depositary will make such rights
available to such Owner upon written notice from the Company to the Depositary
that (a) the Company has elected in its sole discretion to permit such rights to
be exercised and (b) such Owner has executed such documents as the Company has
determined in its sole discretion are reasonably required under applicable law.

          If the Depositary has distributed warrants or other instruments for
rights to all or certain Owners, then upon instruction from such an Owner
pursuant to such warrants or other instruments to the Depositary from such Owner
to exercise such rights, upon payment by such Owner to the Depositary for the
account of such Owner of an amount equal to the purchase price of the Shares to
be received upon the exercise of the rights, and upon payment of the fees and
expenses of the Depositary and any other charges as set forth in such warrants
or other instruments, the Depositary shall, on behalf of such Owner, exercise
the rights and purchase the Shares, and the Company shall cause the Shares so
purchased to be delivered to the Depositary on behalf of such Owner.  As agent
for such Owner, the Depositary will cause the Shares so purchased to be
deposited pursuant to Section 2.02 of the Restricted Deposit Agreement, and
shall, pursuant to Section 2.03 of the Restricted Deposit Agreement, execute and
deliver Receipts to such Owner.  In the case of a distribution pursuant to the
second paragraph of this Article 13, such Receipts shall be legended in
accordance with applicable U.S. laws, and shall be subject to the appropriate
restrictions on sale, deposit, cancellation, and transfer under such laws.

          If the Depositary determines in its discretion that it is not lawful
and feasible to make such rights available to all or certain Owners, it may sell
the rights, warrants or other instruments in proportion to the number of
Restricted American Depositary Shares held by the Owners to whom it has
determined it may not lawfully or feasibly make such rights available, and
allocate the net proceeds of such sales (net of the fees and expenses of the
Depositary as provided in Section 5.09 of the Restricted Deposit

                                     A-11
<PAGE>

Agreement and all taxes and governmental charges payable in connection with such
rights and subject to the terms and conditions of the Restricted Deposit
Agreement) for the account of such Owners otherwise entitled to such rights,
warrants or other instruments, upon an averaged or other practical basis without
regard to any distinctions among such Owners because of exchange restrictions or
the date of delivery of any Receipt or otherwise.

          The Depositary will not offer rights to Owners unless both the rights
and the securities to which such rights relate are either exempt from
registration under the Securities Act with respect to a distribution to all
Owners or are registered under the provisions of such Act; provided, that
                                                           --------
nothing in this Restricted Deposit Agreement shall create, any obligation on the
part of the Company to file a registration statement with respect to such rights
or underlying securities or to endeavor to have such a registration statement
declared effective.  If an Owner of Receipts requests the distribution of
warrants or other instruments, notwithstanding that there has been no such
registration under such Act, the Depositary shall not effect such distribution
unless it has received an opinion from recognized counsel in the United States
for the Company upon which the Depositary may rely that such distribution to
such Owner is exempt from such registration.

          The Depositary shall not be responsible for any failure to determine
that it may be lawful or feasible to make such rights available to Owners in
general or any Owner in particular.

          14.  CONVERSION OF FOREIGN CURRENCY.

          Whenever the Depositary or the Custodian shall receive foreign
currency, by way of dividends or other distributions or the net proceeds from
the sale of securities, property or rights, and if at the time of the receipt
thereof the foreign currency so received can in the judgment of the Depositary
be converted on a reasonable basis into Dollars and the resulting Dollars
transferred to the United States, the Depositary shall convert or cause to be
converted, by sale or in any other manner that it may determine, such foreign
currency into Dollars, and such Dollars shall be distributed to the Owners
entitled thereto or, if the Depositary shall have distributed any warrants or
other instruments which entitle the holders thereof to such Dollars, then to the
holders of such warrants and/or instruments upon surrender thereof for
cancellation.  Such distribution may be made upon an averaged or other
practicable basis without regard to any distinctions among Owners on account of
exchange restrictions, the date of delivery of any Receipt or otherwise and
shall be net of any expenses of conversion into Dollars incurred by the
Depositary as provided in Section 5.09 of the Restricted Deposit Agreement.

                                     A-12
<PAGE>

          If such conversion or distribution can be effected only with the
approval or license of any government or agency thereof, the Depositary shall
file such application for approval or license, if any, as it may deem desirable.

          If at any time the Depositary shall determine that in its judgment any
foreign currency received by the Depositary or the Custodian is not convertible
on a reasonable basis into Dollars transferable to the United States, or if any
approval or license of any government or agency thereof which is required for
such conversion is denied or in the opinion of the Depositary is not obtainable,
or if any such approval or license is not obtained within a reasonable period as
determined by the Depositary, the Depositary may distribute the foreign currency
(or an appropriate document evidencing the right to receive such foreign
currency) received by the Depositary to, or in its discretion may hold such
foreign currency uninvested and without liability for interest thereon for the
respective accounts of, the Owners entitled to receive the same.

          If any such conversion of foreign currency, in whole or in part,
cannot be effected for distribution to some of the Owners entitled thereto, the
Depositary may in its discretion make such conversion and distribution in
Dollars to the extent permissible to the Owners entitled thereto and may
distribute the balance of the foreign currency received by the Depositary to, or
hold such balance uninvested and without liability for interest thereon for the
respective accounts of, the Owners entitled thereto.

          15.  RECORD DATES.

          Whenever any cash dividend or other cash distribution shall become
payable or any distribution other than cash shall be made, or whenever rights
shall be issued with respect to the Deposited Securities, or whenever the
Depositary shall receive notice of any meeting of holders of Shares or other
Deposited Securities, or whenever for any reason the Depositary causes a change
in the number of Shares that are represented by each Restricted American
Depositary Share, or whenever the Depositary shall find it necessary or
convenient, the Depositary shall fix a record date, which shall be the record
date, if any, established by the Company for such purpose or, if different, as
close thereto as practicable, (a) for the determination of the Owners of
Receipts who shall be (i) entitled to receive such dividend, distribution or
rights or the net proceeds of the sale thereof or (ii) entitled to give
instructions for the exercise of voting rights at any such meeting, or (b) on or
after which each Restricted American Depositary Share will represent the changed
number of Shares, subject to the provisions of the Restricted Deposit Agreement.

          16.  VOTING OF DEPOSITED SECURITIES.

          Upon receipt of notice of any meeting of holders of Shares or other
Deposited Securities, if requested in writing by the Company, the Depositary
shall, as

                                     A-13
<PAGE>

soon as practicable thereafter, mail to the Owners of Receipts a notice, the
form of which notice shall be in the sole discretion of the Depositary, which
shall contain (a) all of the information contained in such notice of meeting
received by the Depositary from the Company, (b) a statement that the Owners of
Receipts as of the close of business on a specified record date will be
entitled, subject to any applicable provision of law and of the Memorandum and
Articles of Association of the Company, to instruct the Depositary as to the
exercise of the voting rights, if any, pertaining to the amount of Shares or
other Deposited Securities represented by their respective Restricted American
Depositary Shares, (c) a statement that Owners who instruct the Depositary as to
the exercise of their voting rights will be deemed to have instructed the
Depositary or its authorized representative to call for a poll with respect to
each matter for which such instructions are given, subject to any applicable
provisions of Irish law and of the Memorandum and Articles of Association of the
Company and (d) if applicable, a statement as to the manner in which such
instructions may be given, including an express indication that instructions may
be given or deemed given in accordance with the last sentence of this paragraph
if no instruction is received, to the Depositary to give a discretionary proxy
to a person designated by the Company. Upon the written request of an Owner of a
Receipt on such record date, received on or before the date established by the
Depositary for such purpose, the Depositary shall endeavor insofar as
practicable to vote or cause to be voted the amount of Shares or other Deposited
Securities represented by such Restricted American Depositary Shares evidenced
by such Receipt in accordance with the instructions set forth in such request.
Accordingly, the Depositary will cause its authorized representative to attend
each meeting of holders of Shares and call for a poll as instructed in
accordance with clause (c) above for the purpose of effecting such vote. The
Depositary shall not vote or attempt to exercise the right to vote that attaches
to the Shares or other Deposited Securities, other than in accordance with such
instructions. If no instructions are received by the Depositary from any Owner
with respect to any of the Deposited Securities represented by the Restricted
American Depositary Shares evidenced by such Owner's Receipts on or before the
date established by the Depositary for such purpose, the Depositary will deem
such Owner to have instructed the Depositary to give a discretionary proxy to a
person designated by the Company with respect to such Deposited Securities and
the Depositary will give a discretionary proxy to a person designated by the
Company to vote such Deposited Securities; provided, that no such instructions
will be deemed given and no such discretionary proxy will be given when the
Company notifies the Depositary (and the Company agrees to provide such notice
as promptly as practicable in writing) that the matter to be voted upon is one
of the following:

          1.  is a matter not submitted to shareholders by means of a proxy
          statement comparable to that specified in Schedule 14-A of the
          Commission;

                                     A-14
<PAGE>

          2.  is the subject of a counter-solicitation, or is part of a proposal
          made by a shareholder which is being opposed by management (i.e., a
          contest);

          3.  relates to a merger or consolidation (except when the Company's
          proposal is to merge with its own wholly-owned subsidiary, provided
          its shareholders dissenting thereto do not have rights of appraisal);

          4.  involves right of appraisal;

          5.  authorizes mortgaging of property;

          6.  authorizes or creates indebtedness or increases the authorized
          amount of indebtedness;

          7.  authorizes or creates preferred shares or increases the authorized
          amount of existing preferred shares;

          8.  alters the terms or conditions of any shares of the Company's
          stock then outstanding or existing indebtedness;

          9.  involves waiver or modification of preemptive rights (except when
          the Company's proposal is to waive such rights with respect to
          ordinary shares being offered pursuant to stock option or purchase
          plans involving the additional issuance of not more than 5% of the
          Company's outstanding ordinary shares (see Item 12 below));

          10.  alters voting provisions or the proportionate voting power of a
          class of shares, or the number of its votes per share (except where
          cumulative voting provisions govern the number of votes per share for
          election of directors and the Company's proposal involves a change in
          the number of its directors by not more than 10% or not more than one)

          11.  changes existing quorum requirements with respect to shareholder
          meetings;

          12.  authorizes issuance of ordinary shares, or options to purchase
          ordinary shares, to directors, officers, or employees in an amount
          which exceeds 5% of the total amount of the class outstanding (when no
          plan is amended to extend its duration, the Company shall factor into
          the calculation the number of ordinary shares that remain available
          for issuance, the number of ordinary shares subject to outstanding
          options and any ordinary shares being added; should there be more than
          one plan being considered at the same meeting, all ordinary shares are
          aggregated).

                                     A-15
<PAGE>

          13.  authorizes

               (a) a new profit-sharing or special remuneration plan, or a new
               retirement plan, the annual cost of which will amount to more
               than 10% of average annual income before taxes for the preceding
               five years, or

               (b) the amendment of an existing plan which would bring its costs
               above 10% of such average annual income before taxes (should
               there be more than one plan being considered at the same meeting,
               all costs are aggregated; exceptions may be made in cases of (a)
               retirement plans based on agreement or negotiations with labor
               unions (or which have been or are to be approved by such unions);
               and (b) any related retirement plan for benefit of non-union
               employees having terms substantially equivalent to the terms of
               such union-negotiated plan, which is submitted for action of
               stockholders concurrently with such union-negotiated plan);

          14.  changes the purposes or powers of the Company to an extent which
          would permit it to change a materially different line of business and
          it is the Company's stated intention to make such a change;

          15.  authorizes the acquisition of property, assets, or a company,
          where the consideration to be given has a fair value of 20% or more of
          the market value of the previously outstanding shares;

          16.  authorizes the sale or other disposition of assets or earning
          power of 20% or more of those existing prior to the transaction;

          17.  authorizes a transaction not in the ordinary course of business
          in which an officer, director or substantial security holder has a
          direct or indirect interest;

          18.  reduces earned surplus by 51% or more, or reduces earned surplus
          to an amount less than the aggregate of three years' ordinary share
          dividends computed at the current dividend rate.

          17.  CHANGES AFFECTING DEPOSITED SECURITIES.

          In circumstances where the provisions of Section 4.03 of the
Restricted Deposit Agreement do not apply, upon any change in nominal value,
change in par value, split-up, consolidation, or any other reclassification of
Deposited Securities, or upon any recapitalization, reorganization, merger or
consolidation, or sale of assets affecting the

                                     A-16
<PAGE>

Company or to which it is a party, any securities which shall be received by the
Depositary or a Custodian in exchange for or in conversion of or in respect of
Deposited Securities shall be treated as new Deposited Securities under the
Restricted Deposit Agreement, and Restricted American Depositary Shares shall
thenceforth represent, in addition to the existing Deposited Securities, the
right to receive the new Deposited Securities so received in exchange or
conversion, unless additional Receipts are delivered pursuant to the following
sentence. In any such case the Depositary may execute and deliver additional
Receipts as in the case of a dividend in Shares, or call for the surrender of
outstanding Receipts to be exchanged for new Receipts specifically describing
such new Deposited Securities.

          18.  LIABILITY OF THE COMPANY AND DEPOSITARY.

          Neither the Depositary nor the Company nor any of their respective
directors, employees, agents or affiliates shall incur any liability to any
Owner or Beneficial Owner of any Receipt, if by reason of any provision of any
present or future law or regulation of the United States or any other country,
or of any other governmental or regulatory authority, or by reason of any
provision, present or future, of the Memorandum and Articles of Association of
the Company, or by reason of any provision of any securities issued or
distributed by the Company, or any offering or distribution thereof, or by
reason of any act of God or war or other circumstances beyond its control, the
Depositary or the Company shall be prevented, delayed or forbidden from or be
subject to any civil or criminal penalty on account of doing or performing any
act or thing which by the terms of the Restricted Deposit Agreement or Deposited
Securities it is provided shall be done or performed; nor shall the Depositary
or the Company or any of their respective directors, employees, agents or
affiliates incur any liability to any Owner or Beneficial Owner of a Receipt by
reason of any non-performance or delay, caused as aforesaid, in the performance
of any act or thing which by the terms of the Restricted Deposit Agreement it is
provided shall or may be done or performed, or by reason of any exercise of, or
failure to exercise, any discretion provided for in the Restricted Deposit
Agreement.  Where, by the terms of a distribution pursuant to Section 4.01, 4.02
or 4.03 of the Restricted Deposit Agreement, or an offering or distribution
pursuant to Section 4.04 of the Restricted Deposit Agreement, such distribution
or offering may not be made available to Owners of Receipts, and the Depositary
may not dispose of such distribution or offering on behalf of such Owners and
make the net proceeds available to such Owners, then the Depositary shall not
make such distribution or offering, and shall allow any rights, if applicable,
to lapse.  Neither the Company nor the Depositary assumes any obligation or
shall be subject to any liability under the Restricted Deposit Agreement to
Owners or Beneficial Owners of Receipts, except that they agree to perform their
obligations specifically set forth in the Restricted Deposit Agreement without
negligence or bad faith.  The Depositary shall not be subject to any liability
with respect to the validity or worth of the Deposited Securities.  Neither the
Depositary nor the Company shall be under any obligation to appear in, prosecute
or defend any action, suit, or other

                                     A-17
<PAGE>

proceeding in respect of any Deposited Securities or in respect of the Receipts,
which in its opinion may involve it in expense or liability, unless indemnity
satisfactory to it against all expense and liability shall be furnished as often
as may be required, and the Custodian shall not be under any obligation
whatsoever with respect to such proceedings, the responsibility of the Custodian
being solely to the Depositary. Neither the Depositary nor the Company shall be
liable for any action or nonaction by it in reliance upon the advice of or
information from legal counsel, accountants, any person presenting Shares for
deposit, any Owner or Beneficial Owner of a Receipt, or any other person
believed by it in good faith to be competent to give such advice or information.
The Depositary shall not be responsible for any failure to carry out any
instructions to vote any of the Deposited Securities, or for the manner in which
any such vote is cast or the effect of any such vote, provided that any such
action or nonaction is in good faith. The Depositary shall not be liable for any
acts or omissions made by a successor depositary whether in connection with a
previous act or omission of the Depositary or in connection with a matter
arising wholly after the removal or resignation of the Depositary, provided that
in connection with the issue out of which such potential liability arises, the
Depositary performed its obligations without negligence or bad faith while it
acted as Depositary. The Company agrees to indemnify the Depositary, its
directors, employees, agents and affiliates and any Custodian against, and hold
each of them harmless from, any liability or expense (including, but not limited
to, the expenses of counsel) which may arise out of acts performed or omitted,
in accordance with the provisions of the Restricted Deposit Agreement and of the
Receipts, as the same may be amended, modified, or supplemented from time to
time, (i) by either the Depositary or a Custodian or their respective directors,
employees, agents and affiliates, except for any liability or expense arising
out of the negligence or bad faith of either of them, or (ii) by the Company or
any of its directors, employees, agents and affiliates. No disclaimer of
liability under the Securities Act is intended by any provision of the
Restricted Deposit Agreement.

          19.  RESIGNATION AND REMOVAL OF THE DEPOSITARY; APPOINTMENT OF
SUCCESSOR CUSTODIAN.

          The Depositary may at any time resign as Depositary hereunder by
written notice of its election so to do delivered to the Company, such
resignation to take effect  upon the appointment of a successor depositary and
its acceptance of such appointment as provided in the Restricted Deposit
Agreement.  The Depositary may at any time be removed by the Company by written
notice of such removal, effective upon the appointment of a successor depositary
and its acceptance of such appointment as provided in the Restricted Deposit
Agreement.  Whenever the Depositary in its discretion determines that it is in
the best interest of the Owners of Receipts to do so, it may appoint a
substitute or additional custodian or custodians.

                                     A-18
<PAGE>

          20.  AMENDMENT.

          The form of the Receipts and any provisions of the Restricted Deposit
Agreement may at any time and from time to time be amended by agreement between
the Company and the Depositary without the consent of Owners or Beneficial
Owners of Receipts in any respect which they may deem necessary or desirable,
including, without limitation, amendments agreed upon pursuant to Section 2.09
of the Restricted Deposit Agreement.  Any amendment which shall impose or
increase any fees or charges (other than taxes and other governmental charges,
registration fees and cable, telex or facsimile transmission costs, delivery
costs or other such expenses), or which shall otherwise prejudice any
substantial existing right of Owners of Receipts, shall, however, not become
effective as to outstanding Receipts until the expiration of thirty days after
notice of such amendment shall have been given to the Owners of outstanding
Receipts.  Every Owner of a Receipt at the time any amendment so becomes
effective shall be deemed, by continuing to hold such Receipt, to consent and
agree to such amendment and to be bound by the Restricted Deposit Agreement as
amended thereby.  In no event shall any amendment impair the right of the Owner
of any Receipt to surrender such Receipt and receive therefor the Deposited
Securities represented thereby except in order to comply with mandatory
provisions of applicable law.

          21.  TERMINATION OF RESTRICTED DEPOSIT AGREEMENT.

          The Depositary at any time at the direction of the Company, shall
terminate the Restricted Deposit Agreement by mailing notice of such termination
to the Owners of all Receipts then outstanding at least 90 days prior to the
date fixed in such notice for such termination.  The Depositary may likewise
terminate the Restricted Deposit Agreement by mailing notice of such termination
to the Company and the Owners of all Receipts then outstanding if at any time 90
days shall have expired after the Depositary shall have delivered to the Company
a written notice of its election to resign and a successor depositary shall not
have been appointed and accepted its appointment as provided in the Restricted
Deposit Agreement.  On and after the date of termination, the Owner of a Receipt
will, upon (a) surrender of such Receipt at the Corporate Trust Office of the
Depositary, (b) payment of the fee of the Depositary for the surrender of
Receipts referred to in Section 2.05 of the Restricted Deposit Agreement, and
(c) payment of any applicable taxes or governmental charges, be entitled to
delivery, to him or upon his order, of the amount of Deposited Securities
represented by the Restricted American Depositary Shares evidenced by such
Receipt.  If any Receipts shall remain outstanding after the date of
termination, the Depositary thereafter shall discontinue the registration of
transfers of Receipts, shall suspend the distribution of dividends to the Owners
thereof, and shall not give any further notices or perform any further acts
under the Restricted Deposit Agreement, except that the Depositary shall
continue to collect dividends and other distributions pertaining to Deposited
Securities, shall sell rights and other property as provided in the Restricted
Deposit Agreement, and shall continue to deliver Deposited

                                     A-19

Securities, together with any dividends or other distributions received with
respect thereto and the net proceeds of the sale of any rights or other
property, in exchange for Receipts surrendered to the Depositary (after
deducting, in each case, the fee of the Depositary for the surrender of a
Receipt, any expenses for the account of the Owner of such Receipt in accordance
with the terms and conditions of the Restricted Deposit Agreement, and any
applicable taxes or governmental charges). At any time after the expiration of
one year from the date of termination, the Depositary may sell the Deposited
Securities then held under the Restricted Deposit Agreement and may thereafter
hold uninvested the net proceeds of any such sale, together with any other cash
then held by it thereunder, unsegregated and without liability for interest, for
the pro rata benefit of the Owners of Receipts which have not theretofore been
surrendered, such Owners thereupon becoming general creditors of the Depositary
with respect to such net proceeds. After making such sale, the Depositary shall
be discharged from all obligations under the Restricted Deposit Agreement,
except to account for such net proceeds and other cash (after deducting, in each
case, the fee of the Depositary for the surrender of a Receipt, any expenses for
the account of the Owner of such Receipt in accordance with the terms and
conditions of the Restricted Deposit Agreement, and any applicable taxes or
governmental charges). Upon the termination of the Restricted Deposit Agreement,
the Company shall be discharged from all obligations under the Restricted
Deposit Agreement except for its obligations to the Depositary with respect to
indemnification, charges, and expenses.

          22. DISCLOSURE OF INTERESTS.

          Notwithstanding any other provision of this Receipt or the Deposit
Agreement, each Owner and Beneficial Owner agrees to be bound by and subject to
Irish law and the Memorandum and Articles of Association of the Company (to the
same extent as if such Restricted American Depositary Shares evidenced by such
Receipt were the Shares represented by such Restricted American Depositary
Shares evidenced by such Receipt, provided, however, that such provisions shall
apply to such persons only to the extent feasible), and to provide such
information to the Company relating to ownership of the Shares as may be
required thereunder. Under Irish law, as in effect on the date of the Deposit
Agreement, a person who acquires an interest in 5% or more of the Shares, must
notify the Company within five business days of its interest and of certain
circumstances affecting that interest. In addition, such person must give notice
of any change in its interest above the 5% level and any reduction thereof below
the 5% level. Failure of an Owner or Beneficial Owner to provide the required
information within the prescribed time period and in the prescribed manner is an
offense under Irish law and will result in no right or interest in respect of
the relevant shares being enforceable by action or legal proceedings under Irish
law (including voting rights and certain rights as to dividends in respect of
the Shares represented by such American Depositary Shares).

          If the Company requests information from the Depositary or the
Custodian, as the registered owners of Shares, pursuant to Irish law or the
Memorandum

                                     A-20
<PAGE>

and Articles of Association of the Company, the obligations of the Depositary or
the Custodian, as the case may be, shall be limited to disclosing to the Company
such information relating to the Shares in question as has in each case been
recorded by it pursuant to the terms of the Deposit Agreement.

CBT Group Completes Acquisition of Knowledge Well

CBT Group Gains Access to Major New Market Opportunities Through Knowledge Well
Business Offerings

REDWOOD CITY, Calif., June 24 /PRNewswire/ -- CBT Group (Nasdaq: CBTSY - news),
                                                                 -----   ----
a leading provider of interactive education software for information technology
training, today announced that it has completed the acquisition of Knowledge
Well, a provider of business, management and professional education using online
learning technologies.  The acquisition was approved overwhelmingly by CBT's
shareholders earlier this month, with approximately 99 percent of the
shareholders that voted ratifying the acquisition.

"This is a major development for CBT Group," commented William G. McCabe, CBT
Group chairman. "CBT Group was instrumental in creating and defining the
interactive education software space in the information technology arena and has
continually advanced the boundaries of that marketplace.  Knowledge Well has
also been a leader, creating a new model for the delivery of business degrees
and business and professional education using online learning technologies.
This acquisition brings together an established industry powerhouse and an
innovative pioneer.  We expect the combination to be a powerful one."

"We now have a major opportunity to apply online learning technologies to a
broader professional marketplace," added Gregory M. Priest, CBT Group's
president and chief executive officer.  "The completion of our acquisition of
Knowledge Well is an important step in our ongoing strategy to move CBT Group
forward into the next century.  CBT Group has established itself in the
marketplace by creating a powerful development process and organization and
strong customer relationships.  Throughout the different areas of our business,
CBT Group has made further major strides forward over the last few quarters.  We
have established what we believe is a very strong foundation from which to
address the opportunities that lie before us.  We confidently expect Knowledge
Well to be an important part of our future."

Under the terms of the acquisition agreement signed late last year, CBT Group
issued approximately four million shares in exchange for all of the outstanding
capital stock of Knowledge Well.  In addition, CBT Group assumed outstanding
Knowledge Well options.

The Company expects to account for the transaction as a purchase.  Accordingly,
the company expects to record a one-time charge of approximately $8 million
during the second quarter in connection with the write-off of acquired in-
process research and development, as well as professional fees and other costs
associated with the acquisition.  CBT Group will also record goodwill in
connection with the acquisition, which it plans to amortize at the rate of
approximately

$2 million per quarter. Knowledge Well's results will be included in CBT Group's
financial reports beginning on the closing date.
