                        REPORT OF FOREIGN PRIVATE ISSUER

                        FOR THE MONTH OF SEPTEMBER, 1999

AGREEMENT TO ACQUIRE INTERNATIONAL TELECOMMUNICATION DATA SYSTEMS, INC.

      On September 3, 1999, the registrant, Amdocs Limited ("Amdocs") entered
into an Agreement and Plan of Merger (the "Merger Agreement") with Ivan
Acquisition Corp. and International Telecommunication Data Systems, Inc.
("ITDS"). The Merger Agreement provides for a stock-for-stock merger in which
each ITDS common share will be exchanged for a number of Amdocs Ordinary Shares
equal to $10.50 divided by the ten-day average closing price of the Amdocs
shares immediately prior to the completion of the merger, subject to a maximum
exchange ratio of .4603 and a minimum exchange ratio of .3717. In addition,
Amdocs will convert ITDS options to Amdocs options according to the same
exchange ratio.

      Closing under the Merger Agreement is conditioned on, among other things,
approval by ITDS' shareholders and the expiration or termination of the waiting
period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as
amended. The Merger Agreement contains prohibitions on the solicitation of,
negotiations with respect to, or other activity to facilitate, competing
acquisition proposals involving ITDS, with exceptions for certain actions
determined to be required by the fiduciary duties of ITDS' board of directors.
The Merger Agreement further provides that if any of certain competing
transactions involving ITDS are consummated, ITDS is obligated to pay Amdocs a
break-up fee of $6.42 million. In addition, Amdocs is entitled to exercise
options on ITDS common shares representing in the aggregate 19.9 percent of
ITDS's outstanding common shares, as well as certain ITDS common shares
beneficially owned by a member of ITDS' management.

      The transaction contemplated by the Merger Agreement is intended to
qualify as a tax free reorganization for U.S. federal income tax purposes and
will be accounted for using the purchase accounting method under United States
generally accepted accounting principles.

      Attached and incorporated herein by reference in their entirety as
Exhibits are copies of the Merger Agreement, a related Stock Option Agreement
and Voting Agreement, and a press release announcing the merger.

                  AGREEMENT AND PLAN OF MERGER, dated as of September 3, 1999,
among AMDOCS LIMITED, a company organized under the laws of Guernsey, Channel
Islands ("Parent"), IVAN ACQUISITION CORP., a Delaware corporation and a
wholly-owned subsidiary of Parent ("Acquisition"), and INTERNATIONAL
TELECOMMUNICATION DATA SYSTEMS, INC., a Delaware corporation (the "Company").
The Company and Acquisition are hereinafter sometimes referred to as the
"Constituent Corporations" and the Company as the "Surviving Corporation."

                  WHEREAS the respective Boards of Directors of Parent,
Acquisition and the Company deem it advisable and in the best interests of their
respective stockholders that Parent acquire the Company pursuant to the terms
and conditions of this Agreement, and, in furtherance of such acquisition, such
Boards of Directors have approved the merger of Acquisition with and into the
Company in accordance with the terms of this Agreement and the General
Corporation Law of the State of Delaware (the "Delaware GCL"); and

                  WHEREAS Parent, Acquisition and the Company desire that all
outstanding shares of the capital stock of the Company be converted into the
right to receive fully paid and nonassessable Ordinary Shares, pound
sterling 0.01 par value, of Parent ("Parent Ordinary Shares"), as hereinafter
provided; and

                  WHEREAS concurrently with the execution and delivery of this
Agreement, and as a condition and inducement to Parent and Acquisition to enter
into this Agreement, the Company and Acquisition have entered into an agreement
in the form attached hereto as Exhibit A (the "Option Agreement"), pursuant to
which the Company has granted Acquisition an irrevocable option to purchase up
to 19.9% of the then outstanding shares of Common Stock, $.01 par value, of the
Company ("Company Common Stock"), on the terms and subject to the conditions set
forth therein; and

                  WHEREAS, concurrently with the execution and delivery of this
Agreement and as a condition and inducement to Parent and Acquisition to enter
into this Agreement, certain holders of shares of Company Common Stock have
entered into an agreement with Parent and Acquisition in the form attached
hereto as Exhibit B (the "Voting Agreement"), pursuant to which such holders
have agreed to vote such shares of the Company Common Stock in accordance with
the terms set forth in the Voting Agreement; and

                  WHEREAS, for federal income tax purposes, it is intended that
the merger of Acquisition with and into the Company shall qualify as a
reorganization within the meaning of Section 368(a) of the Internal Revenue Code
of 1986, as amended (the "Code");
<PAGE>   8
                  NOW, THEREFORE, in consideration of the mutual
representations, warranties, covenants, agreements and conditions contained
herein, and in order to set forth the terms and conditions of the merger and the
mode of carrying the same into effect, the parties hereto hereby agree as
follows:

                                    ARTICLE I

                                   THE MERGER

                  SECTION 1.01 The Merger. Subject to the terms and conditions
of this Agreement, at the Effective Time (as hereinafter defined), in accordance
with this Agreement and the Delaware GCL, Acquisition shall be merged with and
into the Company (the "Merger"), the separate existence of Acquisition shall
cease, and the Company shall continue as the surviving corporation under the
corporate name of "ITDS, Inc."

                  SECTION 1.02 Effect of the Merger. Upon the effectiveness of
the Merger, the Surviving Corporation shall succeed to and assume all the rights
and obligations of the Company and Acquisition in accordance with the Delaware
GCL and the Merger shall otherwise have the effects set forth in Section 259 of
the Delaware GCL.

                  SECTION 1.03 Consummation of the Merger. As soon as
practicable after the satisfaction or waiver of the conditions to the
obligations of the parties to effect the Merger set forth herein, provided that
this Agreement has not been terminated previously, the parties hereto will cause
the Merger to be consummated by filing with the Secretary of State of the State
of Delaware a properly executed certificate of merger in accordance with the
Delaware GCL, which shall be effective upon filing or on such later date as may
be specified therein (the time of such effectiveness being the "Effective
Time").

                  SECTION 1.04 Certificate of Incorporation; By-Laws; Directors
and Officers. (a) The Certificate of Incorporation of Acquisition in effect at
the Effective Time shall be the Certificate of Incorporation of the Surviving
Corporation (except that such Certificate of Incorporation shall be amended to
provide that the name of the Surviving Corporation shall be "ITDS, Inc."), until
thereafter amended in accordance with the provisions thereof and as provided by
the Delaware GCL. The By-Laws of Acquisition in effect at the Effective Time
shall be the By-Laws of the Surviving Corporation, until thereafter amended in
accordance with the provisions thereof and the Certificate of Incorporation of
the Surviving Corporation and as provided by the Delaware GCL.

                  (b) From and after the Effective Time and until their
respective successors are duly elected or appointed and qualified, (i) the
directors of Acquisition at the Effective Time shall be the directors of the
Surviving Corporation and (ii) the officers of the Company at the Effective Time
shall be the officers of the Surviving Corporation.

                            CONVERSION OF SECURITIES

                  SECTION 2.01 Conversion of Securities. By virtue of the Merger
and without any action on the part of either Constituent Corporation or any
holder of the capital stock thereof, at the Effective Time:

                           (a) Each share of Common Stock, $.01 par value, of
         Acquisition issued and outstanding immediately prior to the Effective
         Time shall be converted into and become one validly issued, fully paid
         and nonassessable share of Common Stock of the Surviving Corporation;

                           (b) Each share of Company Common Stock that is held
         in the treasury of the Company or of any Subsidiary (as hereinafter
         defined) shall be canceled and retired and no consideration shall be
         paid or delivered in exchange therefor; and

                           (c) Each remaining share of Company Common Stock
         issued and outstanding immediately prior to the Effective Time shall
         be converted into the right to receive a number of Parent Ordinary
         Shares equal to the Exchange Ratio (as hereinafter defined), subject to
         the payment of cash in lieu of fractional shares as provided in Section
         2.03(d) below. For this purpose, the "Exchange Ratio" shall be equal to
         the quotient (rounded to the nearest thousandth, or if there shall not
         be a nearest thousandth, to the next lower thousandth) derived by
         dividing:

                           (i) $10.50; by

                           (ii) the average of the closing prices per Parent
         Ordinary Share on the New York Stock Exchange during the ten
         consecutive trading days ending on the second trading day prior to the
         Effective Time (the "Pre-Closing Average Price");

         provided, however that in no event shall the Exchange Ratio be less
         than .3717 nor more than .4603. If, prior to the Effective Time, Parent
         should split or combine the outstanding Parent Ordinary Shares, or pay
         a stock dividend or other stock distribution in Parent Ordinary Shares,
         then the Exchange Ratio and the Pre-Closing Average Price shall be
         appropriately adjusted to reflect such split, combination, dividend or
         other distribution.

                  All such shares of Company Common Stock to be converted into
Parent Ordinary Shares pursuant to this Section 2.01(c) shall cease to be
outstanding and shall automatically be canceled and retired and shall cease to
exist, and each certificate previously evidencing any such shares shall
thereafter represent the right to receive, upon the surrender of such
certificate in accordance with the provisions of Section 2.03, certificates
evidencing such number of whole


                                       3
<PAGE>   10
Parent Ordinary Shares into which such shares were converted in accordance
herewith. The holders of such certificates previously evidencing such shares of
Company Common Stock outstanding immediately prior to the Effective Time shall
cease to have any rights with respect to such shares of Company Common Stock
except as otherwise provided herein or by law. No fraction of a Parent Ordinary
Share shall be issued and, in lieu thereof, a cash payment shall be made
pursuant to Section 2.03(d).

                  SECTION 2.02 Stock Plans. (a) At the Effective Time, each
stock option granted under the Company's 1996, 1997, 1998 and 1999 Stock
Incentive Plans (the "Company Stock Plans") that is outstanding immediately
prior to the Effective Time shall be assumed by Parent and converted
automatically into an option to purchase Parent Ordinary Shares (a "New Option")
in an amount and at an exercise price determined as provided below:

                  (i) The number of Parent Ordinary Shares to be subject to the
         New Option shall be equal to the product of the number of shares of
         Company Common Stock remaining subject (as of immediately prior to the
         Effective Time) to the original option and the Exchange Ratio, provided
         that any fractional shares resulting from such multiplication shall be
         rounded down to the nearest share; and

                  (ii) The exercise price per Parent Ordinary Share under the
         New Option shall be equal to the exercise price per share of Company
         Common Stock under the original option divided by the Exchange Ratio,
         provided that such exercise price shall be rounded up to the nearest
         cent.

The adjustment provided herein with respect to any options that are "incentive
stock options" (as defined in Section 422 of the Code) shall be and is intended
to be effected in a manner that is consistent with Section 424(a) of the Code.
After the Effective Time, each New Option shall be subject to the same terms and
conditions and shall be exercisable and shall vest upon the same terms and
conditions, as were applicable to the related Company Stock Option immediately
prior to the Effective Time, except that all references to the Company shall be
deemed to be references to Parent.

                  (b) As of the Effective Time, the 1996 Employee Stock Purchase
Plan shall terminate without the purchase of any additional shares of Company
Common Stock and all amounts contributed by participants in such plan shall be
returned to such participants in accordance with Section 16(b)(ii) thereof.

                  SECTION 2.03 Exchange of Certificates. (a) As of the Effective
Time, Parent shall deposit, or shall cause to be deposited, with or for the
account of a bank or trust company designated by Parent, which shall be
reasonably satisfactory to the Company (the "Exchange Agent"), for the benefit
of the holders of shares of Company Common Stock, for exchange in accordance
with this Article II, through the Exchange Agent, certificates evidencing the
Parent Ordinary Shares issuable pursuant to Section 2.01(c) in exchange for
outstanding shares of


                                       4
<PAGE>   11
Company Common Stock (such certificates for Parent Ordinary Shares, together
with any dividends or distributions thereto, being hereinafter referred to as
the "Exchange Fund").

                  (b) As soon as reasonably practicable after the Effective Time
(but in any event within five business days of the Effective Time), Parent will
instruct the Exchange Agent to mail to each holder of record of a certificate or
certificates which immediately prior to the Effective Time evidenced outstanding
shares of Company Common Stock (the "Certificates"), (i) a letter of transmittal
(which shall specify that delivery shall be effected, and risk of loss and title
to the Certificates shall pass, only upon proper delivery of the Certificates to
the Exchange Agent and shall be in such form and have such other provisions as
Parent may reasonably specify) and (ii) instructions to effect the surrender of
the Certificates in exchange for the certificates evidencing Parent Ordinary
Shares. Upon surrender of a Certificate for cancellation to the Exchange Agent
together with such letter of transmittal, duly executed, and such other
customary documents as may be required pursuant to such instructions, the holder
of such Certificate shall be entitled to receive in exchange therefor (A)
certificates evidencing that number of whole Parent Ordinary Shares which such
holder has the right to receive in accordance with Section 2.01(c) in respect of
the shares of Company Common Stock formerly evidenced by such Certificate, and
(B) cash in lieu of a fraction of a Parent Ordinary Share to which such holder
is entitled pursuant to Section 2.03(d) (the Parent Ordinary Shares and cash
described in clauses (A) and (B) being, collectively, the "Merger
Consideration"), and the Certificate so surrendered shall forthwith be canceled.
In the event of a transfer of ownership of shares of Company Common Stock which
is not registered in the transfer records of the Company, Parent Ordinary Shares
and cash (in lieu of a fraction of a Parent Ordinary Share) may be issued and
paid in accordance with this Article II to a transferee if the certificate
evidencing such shares of Company Common Stock is presented to the Exchange
Agent, accompanied by all documents required to evidence and effect such
transfer and by evidence that any applicable stock transfer taxes have been
paid. If any Certificate representing Parent Ordinary Shares is to be issued in
a name other than that in which the Certificate surrendered in exchange therefor
is registered, it shall be a condition of such exchange that the Certificate so
surrendered shall be properly endorsed and otherwise in proper form for transfer
and that the person requesting such exchange shall pay to the Exchange Agent any
transfer or other taxes required by reason of the issuance of certificates for
such Parent Ordinary Shares in a name other than that of the registered holder
of the Certificate surrendered, or shall establish to the satisfaction of the
Exchange Agent that such tax has been paid or is not applicable. Until
surrendered as contemplated by this Section 2.03, each Certificate shall be
deemed at any time after the Effective Time to evidence only the right to
receive upon such surrender the Merger Consideration.

                  (c) No dividends or other distributions declared or made after
the Effective Time with respect to Parent Ordinary Shares with a record date
after the Effective Time shall be paid to the holder of any unsurrendered
Certificate with respect to the Parent Ordinary Shares he is entitled to receive
until the holder of such Certificate shall surrender such Certificate, at which
time such dividends or distributions shall be paid. In no event shall the
persons entitled to receive


                                       5
<PAGE>   12
such dividends or other distributions be entitled to receive interest on such
dividends or other distributions.

                  (d) No certificates or scrip representing a fraction of a
Parent Ordinary Share shall be issued upon the conversion of Company Common
Stock pursuant to Section 2.01(c), and such fractional share interests shall not
entitle the owner thereof to vote or to any rights of a stockholder of Parent.
As promptly as practicable following the Effective Time, the Exchange Agent
shall determine the excess of (A) the number of Parent Ordinary Shares delivered
to the Exchange Agent by Parent pursuant to Section 2.03(a) over (B) the
aggregate number of whole Parent Ordinary Shares to be issued to holders of
Company Common Stock pursuant to Section 2.01(c) (such excess being herein
called the "Excess Shares"). As soon after the Effective Time as practicable,
the Exchange Agent, as agent for the holders of Company Common Stock, shall sell
the Excess Shares at then prevailing prices on the New York Stock Exchange (the
"NYSE"), all in the manner provided in this paragraph (d). The sale of the
Excess Shares by the Exchange Agent shall be executed on the NYSE and shall be
executed in round lots to the extent practicable. Until the net proceeds of such
sale or sales have been distributed to the holders of Company Common Stock
entitled thereto, the Exchange Agent shall hold such proceeds in trust for such
holders of Company Common Stock (the "Common Shares Trust"). The Exchange Agent
shall determine the portion of the Common Shares Trust to which each holder of a
Certificate shall be entitled, if any, by multiplying the amount of the
aggregate net proceeds comprising the Common Shares Trust by a fraction, the
numerator of which is the amount of the fractional share interest in a Parent
Ordinary Share to which such holder is entitled under Section 2.01(c) (or would
be entitled but for this Section 2.03(d)) and the denominator of which is the
aggregate amount of fractional interests in Parent Ordinary Shares to which all
holders of Company Common Stock are entitled.

                  (e) Any portion of the Exchange Fund that remains
undistributed to the holders of Company Common Stock for six months after the
Effective Time shall be delivered to Parent, upon demand, and any holders of
Company Common Stock who have not theretofore complied with this Article II
shall thereafter look only to Parent for the Merger Consideration to which they
are entitled pursuant to this Agreement and any dividends or distributions with
respect to the Merger Consideration.

                  (f) Neither Parent nor the Company shall be liable to any
holder of shares of Company Common Stock for any Parent Ordinary Shares (or
dividends or distributions with respect thereto) or cash from the Exchange Fund
delivered to a public official pursuant to any applicable abandoned property,
escheat or similar law.

                  (g) Parent or the Exchange Agent shall be entitled to deduct
and withhold from the consideration otherwise payable pursuant to this Agreement
to any holder of shares of Company Common Stock such amounts as Parent or the
Exchange Agent is required to deduct and withhold with respect to the making of
such payment under the Code, or any provision of state, local or foreign tax
law. To the extent that amounts are so withheld by Parent or the


                                       6
<PAGE>   13
Exchange Agent, such withheld amounts shall be treated for all purposes of this
Agreement as having been paid to the holder of the shares of Company Common
Stock in respect of which such deduction and withholding was made by Parent or
the Exchange Agent.

                  (h) If any Certificate shall have been lost, stolen or
destroyed, upon the making of an affidavit of that fact by the person or entity
claiming such Certificate to be lost, stolen or destroyed and, if required by
Parent or the Exchange Agent, the posting by such person or entity of a bond in
such reasonable amount as Parent or the Exchange Agent may direct as indemnity
against any claim that may be made against it with respect to such Certificate,
the Exchange Agent shall exchange for such lost, stolen or destroyed Certificate
the Merger Consideration pursuant to this Agreement.

                  SECTION 2.04 Stock Transfer Books. At the Effective Time, the
stock transfer books of the Company shall be closed, and there shall be no
further registration of transfers of shares of Company Common Stock thereafter
on the records of the Company.

                                   ARTICLE III

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

                  The Company represents and warrants to Parent and Acquisition
as follows:

                  SECTION 3.01 Organization and Qualification. The Company is a
corporation duly organized, validly existing and in good standing under the laws
of the State of Delaware and has all requisite corporate power and authority to
own or lease and operate its properties and assets and to carry on its business
as it is now being conducted. The Company is duly qualified as a foreign
corporation to do business, and is in good standing, in each jurisdiction in
which the character of its properties owned or leased or the nature of its
activities makes such qualification necessary, except where the failure to be so
qualified would not have a Material Adverse Effect (as hereinafter defined) on
the Company. As used herein, "Material Adverse Effect" shall mean, with respect
to any party, a material adverse effect on the business, operations, assets,
condition (financial or other) or operating results of such party and its
subsidiaries, taken as a whole.

                  SECTION 3.02 Subsidiaries. (a) Except for shares of the
Subsidiaries or as set forth on Schedule 3.02 hereto (as hereinafter defined),
the Company does not own of record or beneficially, directly or indirectly, (i)
any shares of outstanding capital stock or securities convertible into capital
stock of any other corporation or (ii) any participating interest in any
partnership, joint venture or other non-corporate business enterprise. Each
Subsidiary is a corporation duly organized, validly existing and in good
standing under the laws of its jurisdiction of incorporation and has all
requisite corporate power and authority to own or lease and operate its
properties and to carry on its business as it is now being conducted. Each
Subsidiary is duly qualified as a foreign corporation to do business, and is in
good standing, in each jurisdiction in


                                       7
<PAGE>   14
which the character of its properties owned or leased or the nature of its
activities makes such qualification necessary, except where the failure to be so
qualified would not have a Material Adverse Effect on the Company. Each
Subsidiary and its jurisdiction of formation is identified in the Company's
Annual Report on Form 10-K for the year ended December 31, 1998.

                  (b) Except as set forth on Schedule 3.02 hereto, all the
outstanding shares of capital stock of each Subsidiary are validly issued, fully
paid and nonassessable and are owned by the Company or by a wholly-owned
Subsidiary of the Company, free and clear of any liens, claims, charges,
encumbrances or adverse claims, and there are no proxies outstanding or
restrictions on voting with respect to any such shares.

                  (c) For purposes of this Agreement, the term "Subsidiary"
shall mean any corporation or other business entity of which securities or other
ownership interests having ordinary voting power to elect a majority of the
board of directors or other persons performing similar functions are at the time
owned by the Company and/or one or more other Subsidiaries.

                  SECTION 3.03 Authority Relative to Agreements. The Company has
all requisite corporate power and authority to execute and deliver this
Agreement and the Option Agreement and to perform its respective obligations
hereunder and thereunder. The execution, delivery and performance of this
Agreement and the Option Agreement by the Company and the consummation by it of
the transactions contemplated hereby and thereby have been duly authorized by
the Company's Board of Directors and no other corporate proceedings on the part
of the Company are necessary to authorize this Agreement and the Option
Agreement and the transactions contemplated hereby and thereby, other than the
approval of the Merger by a majority of the stockholders of the Company. This
Agreement and the Option Agreement have been duly executed and delivered by the
Company and, subject to such stockholder approval, constitute legal, valid and
binding obligations of the Company, enforceable against the Company in
accordance with their respective terms.

                  SECTION 3.04 Non-Contravention. Except as set forth on
Schedule 3.04, the execution and delivery of this Agreement and the Option
Agreement by the Company do not and the consummation by the Company of the
transactions contemplated hereby and thereby will not (i) conflict with any
provision of the Certificate of Incorporation or By-Laws of the Company; (ii)
result (with the giving of notice or the lapse of time or both) in any violation
of or default or loss of a benefit under, or permit the acceleration of any
obligation under, any mortgage, indenture, lease, agreement or other
instrument, permit, concession, grant, franchise, license, judgment, order,
decree, statute, law, ordinance, rule or regulation applicable to the Company or
any Subsidiary or their respective properties; or (iii) result in the creation
or imposition of any lien, charge or encumbrance of any nature whatsoever upon
any asset of the Company or any Subsidiary; other than (in the cases of clauses
(ii) and (iii) above) such as could not reasonably be expected, individually or
in the aggregate, to have a Material Adverse Effect on the Company.


                                       8
<PAGE>   15
                  SECTION 3.05 Capitalization. The authorized capital stock of
the Company consists of (i) 40,000,000 shares of Company Common Stock and (ii)
2,000,000 shares of Preferred Stock, $.01 par value ("Preferred Stock"). As of
August 4, 1999, 17,457,996 shares of Company Common Stock were issued and
outstanding, all of which were duly and validly issued, fully paid and
nonassessable, and no shares of Preferred Stock are outstanding. Except for
options to purchase an aggregate 3,141,270 shares of Company Common Stock
granted pursuant to the Company Stock Plans, no subscription, warrant, option,
convertible security, stock appreciation or other right (contingent or other) to
purchase or acquire, or any securities convertible into or exchangeable for, any
shares of any class of capital stock of the Company or any Subsidiary is
authorized or outstanding and there is not any commitment of the Company or any
Subsidiary to issue any shares, warrants, options or other such rights or to
distribute to holders of any class of its capital stock any evidences of
indebtedness or assets. Neither the Company nor any Subsidiary has any
obligation (contingent or other) to purchase, redeem or otherwise acquire any
shares of its capital stock or any interest therein or to pay any dividend or
make any other distribution in respect thereof.

                  SECTION 3.06 SEC Filings. The Company has provided or made
available to Parent and Acquisition true and complete copies of (i) the Annual
Reports of the Company on Form 10-K for the years ended December 31, 1996, 1997
and 1998, (ii) the Quarterly Reports of the Company on Form 10-Q for the three
months ended March 31, 1999 and June 30, 1999, (iii) its proxy or information
statements relating to meetings of, or actions taken without a meeting by, the
stockholders of the Company subsequent to January 1, 1997 and prior to the date
hereof, and (iv) all other reports, statements and registration statements filed
by the Company with the Securities and Exchange Commission (the "SEC")
subsequent to January 1, 1997 (collectively, the "Company SEC Filings"). The
Company SEC Filings (including, without limitation, any financial statements or
schedules included therein) (i) were prepared in compliance with the
requirements of the Securities Act of 1933, as amended (the "Securities Act"),
or the Securities Exchange Act of 1934, as amended (the "Exchange Act"), as the
case may be, and (ii) did not at the time of filing (or if amended, supplemented
or superseded by a filing prior to the date hereof, on the date of that filing)
contain any untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading. None of the Subsidiaries is required to file any forms, reports or
other documents with the SEC.

                  SECTION 3.07 Financial Statements. The consolidated financial
statements of the Company included in the Company SEC Filings have been prepared
in accordance with generally accepted accounting principles consistently applied
and consistent with prior periods, subject, in the case of unaudited interim
consolidated financial statements, to year-end adjustments (which consist of
normal recurring accruals) and the absence of certain footnote disclosures. The
consolidated balance sheets of the Company included in the Company SEC Filings
fairly present the financial position of the Company and the Subsidiaries as of
their respective dates, and the related consolidated statements of operations,
stockholders' equity and cash flows included in the Company SEC Filings fairly
present the results of operations of the


                                       9
<PAGE>   16
Company and the Subsidiaries for the respective periods then ended, subject, in
the case of unaudited interim financial statements, to year-end adjustments
(which consist of normal recurring accruals) and the absence of certain footnote
disclosures. Except for liabilities or obligations that are accrued or reserved
against in the Company's financial statements (or reflected in the notes hereto)
included in the Company SEC Filings made prior to the date hereof or that were
incurred subsequent to June 30, 1999 in the ordinary course of business and
consistent with past practice, and except as set forth on Schedule 3.07 hereto,
none of the Company and its Subsidiaries has any liabilities or obligations
(whether absolute, accrued, contingent or otherwise) of a nature required by
generally accepted accounting principles to be reflected in a consolidated
balance sheet (or reflected in the notes thereto) or which would have a Material
Adverse Effect on the Company.

                  SECTION 3.08 Absence of Certain Changes or Events. Except as
disclosed in the Company SEC Filings made prior to the date hereof or as set
forth on Schedule 3.08 hereto, since December 31, 1998, neither the Company nor
any Subsidiary has (i) issued any stock, bonds or other corporate securities,
(ii) borrowed any amount or incurred any material liabilities (absolute or
contingent), except in the ordinary course of business, (iii) discharged or
satisfied any lien or incurred or paid any obligation or liability (absolute or
contingent) other than current liabilities shown on the consolidated balance
sheet of the Company and the Subsidiaries as of December 31, 1998 referred to in
Section 3.06 hereof and current liabilities incurred since the date of such
balance sheet in the ordinary course of business, (iv) declared or made any
payment or distribution to stockholders or purchased or redeemed any shares of
its capital stock or other securities, (v) mortgaged, pledged or subjected to
lien any of its assets, tangible or intangible, other than liens for current
real property taxes not yet due and payable, (vi) sold, assigned or transferred
any of its tangible assets, or canceled any debts or claims, except in the
ordinary course of business or as otherwise contemplated hereby, (vii) sold,
assigned or transferred any patents, trademarks, trade names, copyrights, trade
secrets or other intangible assets, (viii) made any changes in officer or
executive compensation, (ix) agreed, in writing or otherwise, to take any of the
actions listed in clauses (i) through (viii) above, (x) suffered any Material
Adverse Effect or waived any rights of substantial value, whether or not in the
ordinary course of business, or (xi) entered into any material transaction,
except in the ordinary course of business or as otherwise contemplated hereby.

                  SECTION 3.09 Governmental Approvals. No consent, approval,
order or authorization of, or registration, declaration or filing with, any
federal, state, local or foreign governmental or regulatory authority is
required to be made or obtained by the Company in connection with the execution
and delivery of this Agreement and the Option Agreement by the Company or the
consummation by the Company of the transactions contemplated hereby and thereby,
except for (i) compliance by the Company with the Hart-Scott-Rodino Antitrust
Improvements Act of 1976 (the "HSR Act"), (ii) the filing of a certificate of
merger with the Secretary of State of the State of Delaware in accordance with
the Delaware GCL, (iii) such as are listed on Schedule 3.09 hereto and (iv) such
consents, approvals, orders or authorizations which if not obtained, or
registrations, declarations or filings which if not made, would not materially
adversely affect the ability of the Company to consummate the transactions
contem-


                                       10
<PAGE>   17
plated hereby or by the Option Agreement or the ability of the Surviving
Corporation or any Subsidiary to conduct its business after the Effective Time
substantially as currently conducted by the Company or such Subsidiary.

                  SECTION 3.10 Compliance with Laws. Neither the Company nor any
Subsidiary is in default under or in violation of any order of any court,
governmental authority or arbitration board or tribunal to which the Company or
such Subsidiary is or was subject or in violation of any laws, ordinances,
governmental rules or regulations (including, but not limited to, those relating
to export controls, labor and employment matters and foreign corrupt practices)
to which the Company or any Subsidiary is or was subject, except for such
defaults or violations that, in the aggregate, could not reasonably be expected
to have a Material Adverse Effect on the Company. Neither the Company nor any
Subsidiary has failed to obtain any licenses, permits, franchises or other
governmental authorizations necessary to the ownership of its properties or to
the conduct of its business, which failure could reasonably be expected to have
a Material Adverse Effect on the Company, and, after giving effect to the
transactions contemplated hereby, all such licenses, permits, franchises and
other governmental authorizations will continue to be valid and in full force
and effect except where such failure to be in full force and effect would not
reasonably be expected to have a Material Adverse Effect on the Company.

                  SECTION 3.11 Disclosure Documents. None of the information to
be supplied by the Company for inclusion in (i) the Registration Statement to be
filed with the SEC by Parent on Form F-4 under the Securities Act for the
purpose of registering the Parent Ordinary Shares to be issued in connection
with the Merger (the "Registration Statement") or (ii) the proxy statement to be
distributed in connection with the Company's meeting of stockholders to vote

                  SECTION 3.12 Litigation. Except as set forth on Schedule 3.12
hereto, there is no action, suit, investigation, proceeding or claim pending or,

together with other similar actions, the outcome of which could be reasonably
expected to have a Material Adverse Effect on the Company.

                  SECTION 3.13 Title to Properties. The Company and the
Subsidiaries have good and valid title to the properties and assets reflected on
the consolidated balance sheet of the Company and the Subsidiaries as of June
30, 1999 referred to in Section 3.06 hereof (other than non-material properties
and assets disposed of in the ordinary course of business consistent with past
practice since the date of such balance sheet), and all such properties and
assets are free and clear of liens and encumbrances, except (i) as described on
Schedule 3.13 hereto, (ii) liens for current taxes not yet due and payable and
(iii) minor imperfections of title, if any, not material in amount and not
materially detracting from the value or impairing the use of the property
subject thereto or impairing the operations or proposed operations of the
Company or any of the Subsidiaries (collectively, "Permitted Liens").

                  SECTION 3.14 Real Property Interests. Schedule 3.14 hereto
sets forth a complete and accurate list of (i) the real properties owned by the
Company or any of the Subsidiaries having a net book value as of June 30, 1999
in excess of $500,000 (the "Fee Properties") and (ii) the real properties
leased by the Company or any of the Subsidiaries for annual rental payments in
excess of $500,000 (the "Leased Properties"). Complete and accurate copies of
all leases or other agreements relating to the Leased Properties have been
delivered to Parent and there have been no changes or amendments to such leases
or agreements since such delivery. Each lease or other agreement relating to the
Leased Properties is a valid and subsisting agreement, without any material
default of the Company or any Subsidiary thereunder and, to the best knowledge
of the Company, without any material default thereunder of the other party
thereto, and such leases and agreements give the Company and the Subsidiaries
the right to use or occupy, as the case may be, all real properties as are
sufficient and adequate to operate the business of the Company and the
Subsidiaries as it is currently being conducted. Except as set forth on Schedule
3.14, the Company's or any Subsidiary's possession of such property has not been
disturbed nor, to the best knowledge of the Company, has any claim been asserted
against the Company or such Subsidiary materially adverse to its rights in such
leasehold interests.

                  SECTION 3.15 Software. (a) Each of the Company and the
Subsidiaries has valid licenses to all copies of all software that is not owned
by it and is used by it in connection with the conduct of its business ("Third
Party Software"), and the use by the Company or such Subsidiary of such Third
Party Software, including, without limitation, all modifications and
enhancements thereto (whether or not created by the Company or such Subsidiary),
complies with such license (except for such noncompliance as could not,
individually or in the aggregate, be reasonably expected to have a Material
Adverse Effect on the Company). The Company or a Subsidiary owns all right,
title and interest in and to, or has sufficient rights in, all software used by
the Company and the Subsidiaries in providing services to customers and all
software marketed or licensed by the Company and the Subsidiaries to customers
or held for use or in development for marketing and licensing to customers
(collectively, "Proprietary Software"), and all such rights, titles and
interests will continue to be valid and in full force and effect after the
Effective Time.

                  (b) None of the Third Party Software or Proprietary Software,
no use thereof by the Company or any Subsidiary, and no permitted use thereof by
any licensee infringes upon or violates in any respect material to the business
of the Company any patent, copyright, trade secret or other intellectual
property or contractual right of any customer or other person or entity, and no
claim or demand with respect to any such infringement or violation has been made
or, to the knowledge of the Company, threatened.

                  (c) To the best knowledge of the Company, there are no viruses
in the Proprietary Software and there are no defects in the Proprietary Software
that would prevent such software from performing in all material respects the
tasks and functions that it was intended to perform except those that can be
cured without a Material Adverse Effect on the Company.

                  (d) Except as set forth on Schedule 3.15 hereto, all
Proprietary Software that contains or calls on a calendar function, including,
without limitation, any function that is indexed to a computer processing unit
clock or provides specific dates or calculates spans of dates, (i) is capable of
recognizing, processing, managing, representing, interpreting and manipulating
correctly date-related data for dates earlier and later than January 1, 2000,
(ii) has the ability to provide date recognition for any data element without
limitation, (iii) has the ability to function automatically into and beyond the
year 2000 without human intervention and without any change in operations
associated with the advent of the year 2000, (iv) has the ability to interpret
data, dates and time correctly into and beyond the year 2000, (v) has the
ability not to produce noncompliance in existing data, nor otherwise corrupt
such data, into and beyond the year 2000, (vi) has the ability to process
correctly after January 1, 2000, data containing dates before that date, and
(vii) has the ability to recognize all "leap year" dates, including February 29,
2000 ("Year 2000 Functionality"). The Company and the Subsidiaries are in
compliance with all commitments made to customers with respect to the Year 2000
Functionality of the Proprietary Software or Third Party Software used in the
operations of the Company and the Subsidiaries.

                  SECTION 3.16 Intellectual Property Rights. The Company and the
Subsidiaries own or hold, or are validly licensed or have a legal right to use,
all patents, trademarks and trade names, trademark and trade name registrations,
servicemark, brandmark and brand name registrations and copyrights, the
applications therefor and the licenses with respect thereto (collectively,
"Intellectual Property Rights") that are necessary to the conduct of the
business of the Company and the Subsidiaries as conducted as of the date hereof.
Except as set forth on Schedule 3.16 hereto, (i) the Company and the
Subsidiaries conduct such business in all material respects without infringement
or claim of infringement of any Intellectual Property Right of others and the
conduct by the Surviving Corporation after the Effective Time of such business,
in substantially the same manner as it is currently conducted, will not infringe
or misappropriate or otherwise violate in any respect material to the business
of the Company the Intellectual Property Rights of any other person or
constitute in any respect material to the business of the Company a breach or
violation of any agreement relating to the Intellectual Property Rights of the
Company and the Subsidiaries (other than as a result of agreements to which
Parent or any of its affiliates is a party); (ii) the Company or a Subsidiary
is, and after the consummation of the Merger will be,



                                       13
<PAGE>   20
the sole and exclusive owner of, or have a valid license or other legal right to
use, each Intellectual Property Right that is material to the business of the
Company and the Subsidiaries, in each case free and clear of any liens and
encumbrances (other than Permitted Liens) and, to the best knowledge of the
Company, no person is challenging, infringing, misappropriating or otherwise
violating any such Intellectual Property Rights or claiming that the conduct of
the business of the Company and the Subsidiaries, as conducted as of the date
hereof, infringes, misappropriates or otherwise violates the Intellectual
Property Rights of any third party; (iii) the Company is not aware of any
impediment to the registration of any material trademark that is currently the
subject of any application for registration ; and (iv) none of the material
Intellectual Property Rights of the Company and the Subsidiaries is the subject

                  SECTION 3.17 Trade Secrets. No third party has claimed or
notified the Company or any Subsidiary that any person employed by or otherwise
affiliated with the Company or any Subsidiary has, in respect of his or her
activities to date, violated any of the terms or conditions of his or her
employment contract with any third party, or disclosed or utilized any trade
secrets or proprietary information or documentation of any third party, or
interfered in the employment relationship between any third party and any of its
employees, and to the best knowledge of the Company, no person employed by or
otherwise affiliated with the Company or any Subsidiary has employed any trade
secrets or any information or documentation proprietary to any former employer,
or violated any confidential relationship which such person may have had with
any third party, in connection with the development or sale of any products of
the Company or any Subsidiary.

                  SECTION 3.18 Labor Matters. Neither the Company nor any of the
Subsidiaries is or has been a party to any collective bargaining or union
agreement, and no such agreement is or has been applicable to any employees of
the Company or any of the Subsidiaries. There are not any controversies between
the Company or any of the Subsidiaries and any of such employees that might
reasonably be expected to have a Material Adverse Effect on the Company, or any
unresolved labor union grievances or unfair labor practice or labor arbitration
proceedings pending, or, to the best knowledge of the Company, threatened
against the Company or any Subsidiary. To the best knowledge of the Company,
there are no labor unions or other organizations representing or purporting to
represent any employees of the Company or any of the Subsidiaries and there are
not any organizational efforts currently being made or threatened involving any
of such employees.

                  SECTION 3.19 Severance Arrangements. Except as set forth on

or any Subsidiary of the nature of any of the transactions contemplated by this
Agreement or (ii) providing severance benefits in excess of those generally

                                       14
<PAGE>   21
conditioned upon a change of control, after the termination of employment of
such employees regardless of the reason for such termination of employment.

nor any Subsidiary has incurred any material liability with respect to a Plan
that is currently due and owing and has not yet been satisfied, including,
without limitation, under ERISA (including, without limitation, Title I or Title
IV thereof), the Code or other applicable law, and no event has occurred, and,
to the best knowledge of the Company, there exists no condition or set of

                  SECTION 3.25 Certain Transactions. Except as disclosed in the
Company SEC Filings made prior to the date hereof or as set forth on Schedule
3.25 hereto, there are no existing or proposed material transactions or
arrangements between the Company or any Subsidiary and (i) any director or
executive officer of the Company or (ii) any other person or entity controlling
or under common control with the Company.

                  SECTION 3.26 Insurance. The Company and the Subsidiaries

insurance providing insurance coverage to or for the Company or any of the
Subsidiaries for events or occurrences arising or taking place, in the case of
occurrence type insurance, and for claims made and/or suits commenced, in the
case of claims-made type insurance, that provide insurance in such amounts and
against such risks as is customary for companies engaged in similar businesses
to protect the employees, properties, assets, businesses and operations of the
Company and the Subsidiaries. Except as set forth on Schedule 3.26 hereto, all
premiums with respect thereto covering all periods up to and including the date
hereof have been paid, and no notice of cancellation or termination has been
received with respect to any such policy. All such policies are in full force

will not in any way in any material respect be affected by, or terminate or
lapse by reason of, any of the transactions contemplated hereby.

                  SECTION 3.27 State Takeover Statute. Prior to the date hereof,
the Board of Directors of the Company has approved this Agreement, the Option
Agreement and the Merger and the other transactions contemplated hereby and
thereby, and such approval is sufficient to render inapplicable to the Merger
and any of such other transactions the provisions of Section 203 of the Delaware
GCL.

by the holders of Company Common Stock is fair to such holders from a financial
point of view, a copy of which opinion has been delivered to Parent.

                  SECTION 3.29 Brokers. No person is entitled to any brokerage
or finder's fee or commission in connection with the transactions contemplated
by this Agreement as a result of any action taken by or on behalf of the
Company, other than Lehman Brothers Inc. pursuant to an engagement letter dated

                                   ARTICLE IV

                    REPRESENTATIONS AND WARRANTIES OF PARENT

                  Parent represents and warrants to the Company as follows:

                  SECTION 4.01 Organization and Qualification. Parent is a
company duly organized, validly existing and in good standing under the laws of
Guernsey, Channel Islands and has all requisite corporate power and authority to
own or lease and operate its properties and assets and to carry on its business
as it is now being conducted. Parent is duly qualified as a foreign corporation
to do business, and is in good standing, in each jurisdiction in which the
character of its properties owned or leased or the nature of its activities
makes such qualification necessary, except where the failure to be so qualified
would not have a Material Adverse Effect on Parent.

                  SECTION 4.02 Subsidiaries. Each subsidiary of Parent is a
corporation duly organized, validly existing and, where applicable, in good
standing under the laws of its jurisdiction of incorporation and has all
requisite corporate power and authority to own or lease and operate its
properties and to carry on its business as it is now being conducted. Each
subsidiary of Parent is duly qualified as a foreign corporation to do business,
and is in good standing, in each jurisdiction in which the character of its
properties owned or leased or the nature of its activities makes such
qualification necessary, except where the failure to be so qualified would not
have a Material Adverse Effect on Parent.

                  SECTION 4.03 Authority Relative to Agreement. Parent has all
requisite corporate power and authority to enter into this Agreement and to
perform its obligations



                                       20
<PAGE>   27
hereunder. The execution and delivery of this Agreement by Parent and the
consummation by Parent of the transactions contemplated hereby have been duly
authorized by the Board of Directors of Parent, and no other corporate
proceedings on the part of Parent (including, without limitation, any action by
its stockholders) are necessary to authorize this Agreement and the transactions
contemplated hereby. This Agreement has been duly executed and delivered by
Parent and constitutes the legal, valid and binding obligation of Parent,
enforceable against Parent in accordance with its terms.

                  SECTION 4.04 Non-Contravention. The execution and delivery of
this Agreement by Parent and the consummation by Parent of the transactions
contemplated hereby will not (i) conflict with any provision of the Memorandum
or Articles of Association of Parent or (ii) result (with the giving of notice
or the lapse of time or both) in any violation of or default or loss of a
benefit under, or permit the acceleration of any obligation under, any mortgage,
indenture, lease, agreement or other instrument, permit, concession, grant,
franchise, license, judgment, order, decree, statute, law, ordinance, rule or
regulation applicable to Parent or any of its properties, other than any such
violation, default, loss or acceleration that would not materially adversely
affect the ability of Parent to consummate the transactions contemplated hereby
and which would not otherwise have a Material Adverse Effect on Parent.

                  SECTION 4.05 Capitalization. The authorized capital stock of
Parent consists of (i) 500,000,000 Ordinary Shares, pound sterling 0.01 par
value, (ii) 50,000,000 Ordinary Nonvoting Shares, pound sterling 0.01 par value,
and (iii) 25,000,000 Preferred Shares, pound sterling 0.01 par value. As of
August 24, 1999, 174,589,951 Ordinary Shares and 24,210,073 Ordinary Nonvoting
Shares were issued and outstanding, all of which were duly and validly issued,
fully paid and nonassessable, and no Preferred Shares were outstanding. Except
for options to purchase an aggregate 6,600,000 Ordinary Shares granted pursuant
to Parent's Stock Option Plans, as of the date hereof no subscription, warrant,
option, convertible security, stock appreciation or other right (contingent or
other) to purchase or acquire, or any securities convertible into or
exchangeable for, any shares of any class of capital stock of Parent or any
subsidiary thereof is authorized or outstanding and as of the date hereof there
is not any commitment of Parent or any such subsidiary to issue any shares,
warrants, options or other such rights or to distribute to holders of any class
of its capital stock any evidences of indebtedness or assets. As of the date
hereof, neither Parent nor any of its subsidiaries has any obligation
(contingent or other) to purchase, redeem or otherwise acquire any shares of its
capital stock or any interest therein or to pay any dividend or to make any
other distribution in respect thereof.

                  SECTION 4.06 SEC Filings. Parent has provided to the Company
true and complete copies of (i) the Annual Report of Parent on Form 20-F for the
year ended September 30, 1998, (ii) the Quarterly Reports of Parent on Form 6-K
for the three months ended December 31, 1998, March 31, 1999 and June 30, 1999,
(iii) its proxy or information statements relating to meetings of, or actions
taken without a meeting by, the stockholders of the Company subsequent to June
1, 1998, and (iv) all other reports, statements and registration statements
filed by Parent with the SEC subsequent to June 1, 1998 (collectively, the
"Parent SEC Filings"). The Parent



                                       21
<PAGE>   28
SEC Filings (including, without limitation, any financial statements or
schedules included therein) (i) were prepared in compliance with the
requirements of the Securities Act or the Exchange Act, as the case may be, and
(ii) did not at the time of filing (or if amended, supplemented or superseded by
a filing prior to the date hereof, on the date of that filing) contain any
untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary in order to make the statements therein, in the
light of the circumstances under which they were made, not misleading.

                  SECTION 4.07 Financial Statements. The consolidated financial
statements of Parent included in the Parent SEC Filings have been prepared in
accordance with generally accepted accounting principles consistently applied
and consistent with prior periods, subject, in the case of unaudited interim
consolidated financial statements, to year-end adjustments (which consist of
normal recurring accruals) and the absence of certain footnote disclosures. The
consolidated balance sheets of Parent included in the Parent SEC Filings fairly
present the financial position of Parent and its subsidiaries as of their
respective dates, and the related consolidated statements of operations,
stockholders' equity and cash flows included in the Parent SEC Filings fairly
present the results of operations of Parent and its subsidiaries for the
respective periods then ended, subject, in the case of unaudited interim
financial statements, to year-end adjustments (which consist of normal recurring
accruals) and the absence of certain footnote disclosures. Except for
liabilities or obligations that are accrued or reserved against in the Company's
financial statements (or reflected in the notes thereto) included in the Company
SEC Filings made prior to the date hereof or that were incurred subsequent to
June 30, 1999 in the ordinary course of business and consistent with past
practice, none of the Company and its Subsidiaries has any liabilities or
obligations (whether absolute, accrued, contingent or otherwise) of a nature
required by generally accepted accounting principles to be reflected in a
consolidated balance sheet (or reflected in the notes thereto) or which would
have a Material Adverse Effect on Parent.

                  SECTION 4.08 Governmental Approvals. No consent, approval,
order or authorization of, or registration, declaration or filing with, any
federal, state, local or foreign governmental or regulatory authority is
required to be made or obtained by Parent in connection with the execution and
delivery of this Agreement by Parent or the consummation by Parent of the
transactions contemplated hereby, except for (i) compliance by Parent with the
HSR Act, (ii) filings pursuant to Securities Act and the Exchange Act and the
rules and regulations promulgated by the SEC thereunder, as contemplated by
Section 6.02 hereof, (iii) the filing of a certificate of merger with the
Secretary of State of the State of Delaware in accordance with the Delaware GCL,
and (iv) such consents, approvals, orders or authorizations which if not
obtained, or registrations, declarations or filings which if not made, would not
materially adversely affect the ability of Parent to consummate the transactions
contemplated hereby.

                  SECTION 4.09 Disclosure Documents. None of the information to
be supplied by Parent or Acquisition for inclusion in the Registration Statement
or the Proxy Statement will, in the case of the Registration Statement, at the
time it becomes effective and at the Effective



                                       22
<PAGE>   29
Time, or, in the case of the Proxy Statement or any amendments thereof or
supplements thereto, at the time of the mailing of the Proxy Statement and any
amendments or supplements thereto, and at the time of the meeting of
stockholders of the Company to be held in connection with the Merger, 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, in light of the circumstances under which they are made, not
misleading. The Registration Statement will comply as to form in all material
respects with the applicable provisions of the Securities Act, and the rules and
regulations promulgated thereunder, except that no representation is made by
Parent with respect to statements made therein based on information supplied by
the Company, or its respective representatives for inclusion in the Registration
Statement or the Proxy Statement or with respect to information concerning the
Company or any of the Subsidiaries incorporated by reference in the Registration
Statement or the Proxy Statement.

                  SECTION 4.10 Compliance with Laws. Neither Parent nor any
subsidiary of Parent is in default under or in violation of any order of any
court, governmental authority or arbitration board or tribunal to which Parent
or such subsidiary is or was subject or in violation of any laws, ordinances,
governmental rules or regulations (including, but not limited to, those relating
to export controls, labor and employment matters and foreign corrupt practices)
to which Parent or any subsidiary of Parent is or was subject, except for such
defaults or violations that, in the aggregate, could not reasonably be expected
to have a Material Adverse Effect on Parent. Neither Parent nor any subsidiary
of Parent has failed to obtain any licenses, permits, franchises or other
governmental authorizations necessary to the ownership of its properties or to
the conduct of its business, which failure could reasonably be expected to have
a Material Adverse Effect on Parent, and, after giving effect to the
transactions contemplated hereby, all such licenses, permits, franchises and
other governmental authorizations will continue to be valid and in full force
and effect except where such failure to be in full force and effect would not
reasonably be expected to have a Material Adverse Effect on Parent.

                  SECTION 4.11 Litigation. There is no action, suit,
investigation, proceeding or claim pending or, to the best knowledge of Parent,
threatened against or affecting Parent or any subsidiary of Parent, or their
respective properties or rights, before any governmental body or arbitration
board or tribunal, either alone or together with other similar actions, the
outcome of which could be reasonably expected to have a Material Adverse Effect
on Parent.

                  SECTION 4.12 Brokers. No person is entitled to any brokerage
or finder's fee or commission in connection with the transactions contemplated
by this Agreement as a result of any action taken by or on behalf of Parent or
Acquisition, other than Goldman Sachs & Co.

and delivered by Acquisition and constitutes the legal, valid and binding
obligation of Acquisition, enforceable against Acquisition in accordance with
its terms.

Certificate of Incorporation or By-Laws of Acquisition or (ii) result (with the
giving of notice or the lapse of time or both) in any violation of or default or
loss of a benefit under, or permit the acceleration of any obligation under, any
mortgage, indenture, lease, agreement, license, judgment, order, decree,
statute, law, ordinance, rule or regulation applicable to Acquisition or its
properties, other than any such violation, default, loss or acceleration that
would not materially adversely affect the ability of Acquisition to consummate
the transactions contemplated hereby.

                  SECTION 5.04 Governmental Approvals. No consent, approval,
order or authorization of, or registration, declaration or filing with, any
federal, state, local or foreign governmental or regulatory authority is
required to be made or obtained by Acquisition in connection with the execution
and delivery of this Agreement by Acquisition or the consummation by Acquisition

contemplated by Section 6.02 hereof, (iii) the filing of a certificate of merger
with the Secretary of State of the State of Delaware in accordance with the
Delaware GCL, and (iv) such consents, approvals, orders or



                                       24
<PAGE>   31
authorizations which if not obtained, or registrations, declarations or filings
which if not made, would not materially adversely affect the ability of
Acquisition to consummate the transactions contemplated hereby.

be declared and paid on the Parent Ordinary Shares to be issued in the Merger;

                  (b) neither Parent nor any of its subsidiaries shall take any
action that would make any representation or warranty of Parent or Acquisition
hereunder inaccurate in any material respect at, or as of any time prior to, the

notice of and convene a meeting (the "Company Meeting") of its stockholders to
consider and vote upon the approval and adoption of this Agreement and the
Merger and for such other purposes as may be necessary or desirable. The Board
of Directors of the Company has determined that the Merger is advisable and in
the best interests of the stockholders of the Company and shall, subject to its
fiduciary duties as advised by counsel, recommend that the stockholders of the
Company vote to approve and adopt this Agreement and the Merger and any other
matters to be submitted to stockholders in connection therewith.

                  (b) Parent and the Company shall, as promptly as practicable,

connection with the vote of the Company's stockholders with respect to the
Merger and the issuance of Parent Ordinary Shares pursuant to the Merger (such
proxy statement/prospectus, together with any amendments thereof or supplements
thereto, in each case in the form or forms mailed to the Company's stockholders,
is herein referred to as, the "Proxy Statement"). Parent will, as promptly as
practicable, prepare and file with the SEC a registration statement on Form F-4
containing the Proxy Statement, in connection with the registration under the
Securities Act of the Parent Ordinary Shares issuable upon conversion of the
shares of Company Common Stock and the other transactions contemplated hereby.
Parent and the Company shall use their best efforts to have or cause the
Registration Statement declared effective as promptly as practicable, including,
without limitation, causing their accountants to deliver necessary or required
instruments such as opinions and certificates, and will take any other action
required or necessary to be taken under federal or state



                                       27
<PAGE>   34
securities laws or otherwise in connection with the registration process. The
Company will use its reasonable best efforts to cause the Proxy Statement to be
mailed to stockholders of the Company at the earliest practicable date and shall
use its reasonable best efforts to hold the Company Meeting as soon as
practicable after the date hereof.

                  (c) Parent and the Company shall notify each other of the
receipt of any comments of the staff of the SEC and of any requests by the staff
for amendments or supplements to the Proxy Statement or the Registration

material respect, any of its covenants or agreements contained herein, the
Company shall pay to Parent, within two business days following such
termination, the fees and expenses referred to in clause (ii) of the preceding
sentence; provided that the fees and expenses described in clauses (i) and (ii)

its covenants or agreements contained herein.

<PAGE>   37

Effective Time and (ii) any material failure of the Company, Parent or
Acquisition, as the case may be, or any officer, director, employee or agent
thereof, to comply with or satisfy any covenant, condition or agreement to be
complied with or satisfied by it hereunder; provided, however, that failure to
give such notice shall not constitute a waiver of any defense that may be
validly asserted.

and after the Effective Time, Parent and the Surviving Corporation shall,

time prior to the date of this Agreement or who becomes prior to the Effective
Time, an officer, director or employee of the Company or any of the Subsidiaries
(the "Indemnified Parties") against all losses, claims, damages, costs,
expenses, liabilities or judgments or amounts that are paid in settlement with
the approval of the indemnifying party (which approval shall not be unreasonably
withheld or delayed) of or in connection with any claim, action, suit,
proceeding or investigation based in whole or in part on or arising in whole or
in part out of the fact that such person is or was a director, officer or
employee of the Company or any of the Subsidiaries, whether pertaining to any
matter existing or occurring at or prior to the Effective Time and whether
asserted or claimed prior to, or at or after, the Effective Time ("Indemnified
Liabilities"), including all losses, claims, damages, costs, expenses,
liabilities or judgments based in whole or in part on, or arising in whole or in
part out of, or pertaining to this Agreement or the transactions contemplated
hereby, in each case to the full extent a corporation is permitted under the
Delaware GCL to indemnify its own directors, officers and employees, as the case
may be (the Company, Parent and the Surviving Corporation, as the case may be,
will pay expenses in advance of the final disposition of any such action or
proceeding to each Indemnified Party to the full extent permitted by law upon
receipt of an undertaking contemplated by Section 145(e) of the Delaware GCL).
Without limiting the foregoing, in the event any such claim, action, suit,
proceeding or investigation is brought against any Indemnified Party (whether
arising before or after the Effective Time), (i) the Indemnified Parties may
retain counsel satisfactory to them and the Company (or them and Parent and the
Surviving Corporation after the Effective Time), (ii) the Company (or after the
Effective Time, Parent and the Surviving Corporation) shall pay all reasonable
fees and expenses of such counsel for the Indemnified Parties promptly as
statements therefor are received, and (iii) the Company (or after the Effective

assist in the vigorous defense of any such matter, provided that none of the
Company, Parent or the Surviving Corporation shall be liable for any settlement
of any claim effected without its written consent, which consent, however, shall
not be unreasonably withheld or delayed. Any Indemnified Party wishing to claim
indemnification under this Section 6.08, upon learning of any such claim,
action, suit or proceeding or investigation, shall promptly notify the Company,
Parent or the Surviving Corporation (but the failure to so notify an
indemnifying party shall not relieve it from any liability which it may have had
under this Section 6.08 except to the extent such failure prejudices such
party), and shall deliver to the Company (or after the Effective Time, Parent
and the Surviving Corporation) the undertaking contemplated by Section 145(e) of
the Delaware GCL. The Indemnified Parties as a group may retain only one law
firm to represent them with respect to each such matter unless there is, under
applicable standards of professional conduct, a

                                       31
<PAGE>   38

Indemnified Parties. The obligations of the parties set forth in this Section
6.08(a) shall be in furtherance of and not in limitation of succeeding
paragraphs of this Section 6.08.

                  (b) From and after the Effective Time, the Surviving
Corporation and Parent will fulfill, assume and honor in all respects the
obligations of the Company pursuant to the Company's Certificate of
Incorporation, Bylaws and any indemnification agreement between the Company and
the Company's directors and officers existing and in force as of the Effective
Time.

                  (c) Parent and the Surviving Corporation shall, until the
sixth anniversary of the Effective Time or such earlier date as may be mutually
agreed upon by Parent, the Surviving Corporation and the applicable Indemnified
Party, cause to be maintained in effect, to the extent available, the policies
of directors' and officers' liability insurance maintained by the Company and
the Subsidiaries as of the date hereof (or policies of at least the same
coverage and amounts containing terms that are not less advantageous to the
insured parties) with respect to claims arising from facts or events that
occurred on or prior to the Effective Time. In lieu of the purchase of such
insurance by Parent or the Surviving Corporation, the Company may purchase a
six-year extended reporting period endorsement ("reporting tail coverage") under
its existing directors' and liability insurance coverage. In no event shall
Parent or the Surviving Corporation be obligated to expend in order to maintain
or procure insurance coverage pursuant to this paragraph (c) any amount per year
in excess of 150% of the aggregate premiums paid by the Company and the
Subsidiaries in the fiscal year ending December 31, 1999 for directors' and
officers' liability insurance.

                  (d) This Section 6.08 shall survive the consummation of the

use its commercially reasonable efforts to cause each such affiliate to deliver
to Parent, on or prior to the Effective Time, a written agreement that the
affiliate will not sell, pledge, transfer or otherwise dispose of shares of
Parent Common Stock issued to such affiliate pursuant to the Merger, except in
compliance with Rule 145 or an exemption from the registration requirements of
the Securities Act.

                  SECTION 6.10 NYSE Listing. Parent shall use its best efforts

the SEC a registration statement on Form S-8 (or other appropriate form) or a
post-effective amendment to

                                       32

the Registration Statement and shall take any action required to be taken under
state securities "blue sky" laws for purposes of registering all shares of
Parent Common Stock issuable after the Effective Time upon exercise of the New

efforts to have such registration statement or post-effective amendment become

Time, but not later than 30 days after the Effective Time. The Company Stock
Plans shall terminate effective as of the Effective Time. Parent shall reserve

substance for letters delivered by independent public accountants in connection
with registration statements similar to the Registration Statement.

                  SECTION 6.13 Stay Bonuses. The Parent and the Company agree
that from and after the date hereof, the Company and Parent shall allocate cash
and options with an aggregate value of approximately $3,500,000 in "stay
bonuses" (of which at least $2,000,000 will be payable in cash) to be paid to
key employees of the Company identified by the Company upon consultation with
Parent. Such stay bonuses shall be in such amounts and payable on such dates,
beginning three months after the Effective Time, as determined by the Company
upon consultation with Parent to such key employees who remain employees in good
standing with the Company.

None of the representations and warranties in this Agreement or in any

of the other incident to the negotiation, preparation and execution of this
Agreement, including the fees and expenses of counsel, accountants, investment

expenses incurred by Acquisition, provided, however, that if this Agreement

which event such party shall consult with the other prior to making such
disclosure).

in this Agreement to the contrary, nothing in this Agreement, expressed or
implied, is intended to confer on any person other than the parties hereto or
their respective permitted successors and assigns, any rights, remedies,
obligations or liabilities under or by reason of this Agreement; provided,
however, that the provisions of Section 6.07 hereof shall accrue to the benefit
of, and shall be enforceable by, each of the current and former directors and
officers of the Company.

                  SECTION 9.10 Assignability. Neither this Agreement nor any of
the parties' rights hereunder shall be assignable by any party hereto without
the prior written consent of the other parties hereto.

                  SECTION 9.11 Amendments. This Agreement may be varied, amended
or supplemented at any time before or after the approval and adoption of this
Agreement by the stockholders of the Company by action of the respective boards
of directors of the Company, Parent and Acquisition, without action by the
stockholders thereof; provided that, after approval and adoption of this
Agreement by the Company's stockholders, no such variance, amendment or
supplement shall, without consent of such stockholders if such action is
required by law, reduce the amount or alter the form of the consideration that
the holders of the capital stock of the Company shall be entitled to receive
upon the Effective Time pursuant to Section 2.05 hereof. Without limiting the
generality of the foregoing, this Agreement may only be amended, varied or
supplemented by an instrument in writing, signed by the parties hereto.

                             STOCK OPTION AGREEMENT


                  STOCK OPTION AGREEMENT, dated as of September 3, 1999, between
INTERNATIONAL TELECOMMUNICATION DATA SYSTEMS, INC., a Delaware corporation
("Issuer"), and AMDOCS LIMITED, a company organized under the laws of Guernsey,
Channel Islands ("Grantee").

                  WHEREAS, Issuer and Grantee have entered into an Agreement and
Plan of Merger, dated as of the date hereof (the "Merger Agreement"), providing
for, among other things, upon the terms and subject to the conditions thereof,
the merger of a newly-formed subsidiary of Grantee with and into Issuer (the
"Merger"); and

                  WHEREAS, as a condition and inducement to Grantee's
willingness to enter into the Merger Agreement, Grantee has requested that
Issuer agree, and Issuer has agreed, to grant Grantee the Option (as defined
below);

                  NOW, THEREFORE, in consideration of the foregoing and the
respective representations, warranties, covenants and agreements set forth
herein, Issuer and Grantee agree as follows:

                  Capitalized terms used but not defined herein shall have the
meanings set forth in the Merger Agreement.

                  1. Grant of Option. (a) Upon the terms and subject to the
conditions set forth herein, Issuer hereby grants to Grantee an unconditional,
irrevocable option (the "Option") to purchase up to 19.9% of the outstanding
shares, at the time of exercise (the "Option Shares"), of Issuer's Common Stock,
$0.01 par value ("Issuer Common Stock"), at a price of $8.125 per share (the
"Exercise Price"), subject to adjustment as set forth herein. Notwithstanding
the foregoing, if at any time that the Option is exercisable pursuant to the
terms and conditions of this Agreement an Alternative Transaction has
theretofore been consummated for a value per share of Issuer Common Stock below
the Exercise Price, then the Exercise Price will be adjusted to such lower
price.

                  (b) In the event that any additional shares of Issuer Common
Stock are either (i) issued or otherwise become outstanding after the date of
this Agreement (other than pursuant to this Agreement) or (ii) redeemed,
repurchased, retired or otherwise cease to be outstanding after the date of the
Agreement, the number of Option Shares shall be increased or decreased, as
<PAGE>   2
appropriate, so that, after such events, the number of Option Shares equals
19.9% of the number of shares of Issuer Common Stock then issued and
outstanding, without giving effect to any shares subject to or issued pursuant
to the Option. Nothing contained in this Section 1(b) or elsewhere in this
Agreement shall be deemed to authorize Issuer or Grantee to breach any provision
of the Merger Agreement.

                  2. Exercise of Option. (a) Grantee may exercise the Option,
with respect to any or all of the Option Shares at any time and from time to
time, subject to the provisions of Section 2(c), upon and subsequent to the
occurrence of a Payment Event under the Merger Agreement, except that (i)
subject to the last sentence of this Section 2(a), the Option will terminate and
be of no further force and effect upon the earliest to occur of (A) six months
after the date of the Payment Event and (B) termination of the Merger Agreement
in accordance with its terms prior to the occurrence of a Payment Event, unless,
in the case of clauses (A) and (B), Grantee could be entitled to receive the
fees and expenses payable pursuant to the first sentence of paragraph (b) of
Section 6.06 of the Merger Agreement following such time or termination upon the
occurrence of certain events, in which case the Option will not terminate until
the later of (x) six months following the time such fees and expenses become
payable and (y) the expiration of the period in which the Grantee has such right
to receive such fees and expenses and (ii) any purchase of Option Shares upon
exercise of the Option will be subject to compliance with the HSR Act and the
obtaining or making of any consents, approvals, orders, notifications or
authorizations, the failure of which to have obtained or made would have the
effect of making the issuance of Option Shares illegal (the "Regulatory
Approvals") and no preliminary or permanent injunction or other order by any
court of competent jurisdiction prohibiting or otherwise restraining such
issuance shall be in effect. Notwithstanding the termination of the Option,
Grantee will be entitled to purchase the Option Shares if it has exercised the
Option in accordance with the terms hereof prior to the termination of the
Option, and the termination of the Option will not affect any rights hereunder
which by their terms do not terminate or expire prior to or as of such
termination.

                  (b) In the event that Grantee wishes to exercise the Option,
it will send to Issuer a written notice (an "Exercise Notice"; the date of which
being herein referred to as the "Notice Date") to that effect specifying (i) the
number of Option Shares, if any, Grantee wishes to purchase pursuant to this
Section 2(b), (ii) the number of Option Shares, if any, with respect to which
Grantee wishes to exercise its Cash-Out Right (as defined herein) pursuant to
Section 7(c), (iii) the denominations of the certificate or certificates
evidencing the Option Shares which Grantee wishes to purchase pursuant to this
Section 2(b) and (iv) a date not earlier than three business days nor later than
30 days from the Notice Date for the closing (an "Option Closing") of such
purchase (an "Option Closing Date"). Any Option Closing will be at an agreed
location and time in New York, New York on the applicable Option Closing Date or
at such later date as may be necessary so as to comply with clause (ii) of
Section 2(a).

                  (c) Notwithstanding anything to the contrary contained herein,
any exercise of the Option and purchase of Option Shares shall be subject to
compliance with applicable laws and

                                        2
<PAGE>   3
regulations, which may prohibit the purchase of all the Option Shares specified
in the Exercise Notice without first obtaining or making certain Regulatory
Approvals. In such event, if the Option is otherwise exercisable and Grantee
wishes to exercise the Option, the Option may be exercised in accordance with
Section 2(b) and Grantee shall acquire the maximum number of Option Shares
specified in the Exercise Notice that Grantee is then permitted to acquire under
the applicable laws and regulations, and if Grantee thereafter obtains the
Regulatory Approvals to acquire the remaining balance of the Option Shares
specified in the Exercise Notice, then Grantee shall be entitled to acquire such
remaining balance. Issuer agrees to use it reasonable best efforts to assist
Grantee in seeking the Regulatory Approvals. In the event (i) Grantee receives
official notice that a Regulatory Approval required for the purchase of any
Option Shares will not be issued or granted or (ii) such Regulatory Approval has
not been issued or granted within six months of the date of the Exercise Notice,
Grantee shall have the right to exercise its Cash-Out Right (as defined herein)
pursuant to Section 7(c) with respect to the Option Shares for which such
Regulatory Approval will not be issued or granted or has not been issued or
granted.

                  (d) If Grantee receives in aggregate (i) the fee payable
pursuant to Section 6.06 of the Merger Agreement, (ii) amounts from the sale or
other disposition of the Option Shares, and (iii) amounts paid pursuant to
Section 7(c) hereof, and the aggregate of such amounts is in excess of the sum
of (A) $8,250,000 plus (B) the amounts paid by Grantee to purchase any Option
Shares, then Grantee, at is sole election, shall either (1) reduce the number of
Option Shares, (2) deliver to the Issuer for cancellation Option Shares
previously purchased by Grantee (valued, for the purposes of this Section 2(d)
at the average closing sale price per share of Issuer Common Stock (or if there
is no sale on such date then the average between the closing bid and ask prices
on any such day) as reported on the NASDAQ National Market System (as reported
in The Wall Street Journal (Northeast edition), or, if not reported thereby, any
other authoritative source) for the ten consecutive trading days preceding the
day on which the amount received by Grantee pursuant to clauses (d)(i), (ii) and
(iii) above exceeds the sum of the of the amounts in clauses (A) and (B) above),
(3) pay cash to the Issuer or (4) any combination thereof, so that the amount
received by Grantee pursuant to clauses (d)(i), (ii) and (iii) above shall not
exceed the sum of the amounts in clauses (A) and (B) above after taking into
account the foregoing actions. Notwithstanding any other provision of this
Agreement, nothing in this Agreement shall affect the ability of Grantee to
receive nor relieve Issuer's obligation to pay the fee or expenses payable
pursuant to Section 6.06 of the Merger Agreement.

                  3. Payment and Delivery of Certificates. (a) At any Option
Closing, Grantee will pay to Issuer in same day funds by wire transfer to a bank
account designated in writing by Issuer an amount equal to the Exercise Price
multiplied by the number of Option Shares to be purchased at such Option
Closing.

                  (b) At any Option Closing, simultaneously with the delivery of
same day funds as provided in Section 3(a), Issuer will deliver to Grantee a
certificate or certificates representing the Option Shares to be purchased at
such Option Closing, which Option Shares will be free and clear of all liens,
claims, charges and encumbrances of any kind whatsoever. If at the time of

                                        3
<PAGE>   4
issuance of Option Shares pursuant to an exercise of the Option hereunder,
Issuer shall have issued any securities similar to rights under a shareholder
rights plan, then each Option Share issued pursuant to such exercise will also
represent such a corresponding right with terms substantially the same as and at
least as favorable to Grantee as are provided under any Issuer shareholder
rights agreement or any similar agreement then in effect.

                  (c) Certificates for the Option Shares delivered at an Option
Closing will have typed or printed thereon a restrictive legend which will read
substantially as follows:

                  "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
                  REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND
                  MAY BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED ONLY IF
                  SO REGISTERED OR IF AN EXEMPTION FROM SUCH REGISTRATION IS
                  AVAILABLE."

It is understood and agreed that the above legend will be removed by delivery of
substitute certificate(s) without such reference if such Option Shares have been
sold in compliance with the registration and prospectus delivery requirements of
the Securities Act, such Option Shares have been sold in reliance on and in
accordance with Rule 144 under the Securities Act or Grantee has delivered to
Issuer a copy of a letter from the staff of the SEC, or an opinion of counsel in
form and substance reasonably satisfactory to Issuer and its counsel, to the
effect that such legend is not required for purposes of the Securities Act.

                  4. Incorporation of Representations and Warranties of Issuer
and Grantee. The representations and warranties of Issuer and Grantee contained
in Articles III and IV of the Merger Agreement are hereby incorporated by
reference herein with the same force and effect as though made pursuant to this
Agreement.

                  5. Representations and Warranties of Issuer. Issuer hereby
additionally represents and warrants to Grantee that Issuer has taken all
necessary corporate and other action to authorize and reserve and, subject to
the expiration or termination of any required waiting period under the HSR Act,
to permit it to issue, and, at all times from the date hereof until the
obligation to deliver Option Shares upon the exercise of the Option terminates,
shall have reserved for issuance, upon exercise of the Option, shares of Issuer
Common Stock necessary for Grantee to exercise the Option, and Issuer will take
all necessary corporate action to authorize and reserve (and shall at all times
maintain, free from pre-emptive rights, sufficient authorized and reserved
shares) for issuance all additional shares of Issuer Common Stock or other
securities which may be issued pursuant to Section 7 upon exercise of the
Option. The shares of Issuer Common Stock to be issued upon due exercise of the
Option, including all additional shares of Issuer Common Stock or other
securities which may be issued pursuant to Section 7, upon issuance pursuant
hereto, will be duly and validly issued, fully paid and nonassessable, and will
be delivered free and clear of all liens, claims, charges and encumbrances of
any kind or nature whatsoever, including, without limitation, any preemptive
rights of any stockholder of Issuer.

                                        4
<PAGE>   5
                  6. Representations and Warranties of Grantee. Grantee hereby
additionally represents and warrants to Issuer that any Option Shares or other
securities acquired by Grantee upon exercise of the Option will not be, and the
Option is not being, acquired by Grantee with a view to the public distribution
thereof. Neither the Option nor any of the Option Shares will be offered, sold,
pledged or otherwise transferred except in compliance with, or pursuant to an
exemption from, the registration requirements of the Securities Act.

                  7. Adjustment upon Changes in Capitalization, Etc. (a) In the
event of any changes in Issuer Common Stock by reason of a stock dividend, stock
split, reverse stock split, stock issuance, merger, recapitalization,
combination, exchange of shares, or similar transaction, the type and number of
shares of securities subject to the Option, and the Exercise Price therefor,
will be adjusted appropriately, and proper provision will be made in the
agreements governing such transaction, so that Grantee will receive upon
exercise of the Option the number and class of shares or other securities or
property that Grantee would have received with respect to Issuer Common Stock if
the Option had been exercised immediately prior to such event or the record date
therefor, as applicable.

                  (b) Without limiting the parties' relative rights and
obligations under the Merger Agreement, in the event that Issuer enters into an
agreement (i) to consolidate with or merge into any person, other than Grantee
or one of its subsidiaries, and Issuer will not be the continuing or surviving
corporation in such consolidation or merger, (ii) to permit any person, other
than Grantee or one of its subsidiaries, to merge into Issuer and Issuer will be
the continuing or surviving corporation, but in connection with such merger, the
shares of Issuer Common Stock outstanding immediately prior to the consummation
of such merger will be changed into or exchanged for stock or other securities
of Issuer or any other person or cash or any other property, or the shares of
Issuer Common Stock outstanding immediately prior to the consummation of such
merger will, after such merger, represent less than 50% of the outstanding
voting securities of the merged company, or (iii) to sell or otherwise transfer
all or substantially all of its assets to any person, other than Grantee or one
of its subsidiaries, then, and in each such case, the agreement governing such
transaction will make proper provision so that the Option will, upon the
consummation of any such transaction and upon the terms and condition set forth
herein, be converted into, or exchanged for, an option with identical terms
appropriately adjusted to acquire the number and class of shares or other
securities or property that Grantee would have received in respect of Issuer
Common Stock if the Option has been exercised immediately prior to such
consolidation, merger, sale, or transfer, or the record date therefor, as
applicable and make any necessary adjustments.

                  (c) If, at any time during the period commencing on the
occurrence of a Payment Event and ending on the termination of the Option in
accordance with Section 2, Grantee sends to Issuer an Exercise Notice indicating
Grantee's election to exercise its right (the "Cash-Out- Right") pursuant to
this Section 7(c) then Issuer shall pay to Grantee, on the Option Closing Date,
in exchange for the cancellation of the Option with respect to such number of
Option Shares as Grantee specifies in the Exercise Notice, an amount in cash
(the "Cash-Out-

                                        5
<PAGE>   6
Price") equal to the amount by which (A) the highest of (i) the price per share
of Issuer Common Stock at which a tender offer or exchange offer therefor has
been made, (ii) the highest price per share of Issuer Common Stock to be paid by
any third-party pursuant to an agreement with the Issuer, (iii) the highest
closing price within the six month period immediately preceding the Notice Date
per share of Issuer Common Stock as reported on the NASDAQ National Market
System (as reported in The Wall Street Journal (Northeast edition), or, if not
reported thereby, any other authoritative source) and (iv) in the event of a
sale of all or a substantial portion of Issuer's assets, the sum of the price
paid in such sale for such assets and the current market value of the remaining
assets of Issuer as determined by a nationally recognized investment banking
firm selected by Grantee, and reasonably acceptable to Issuer, divided by the
number of shares of Issuer Common Stock outstanding at the time of such sale
exceeds (B) the Exercise Price multiplied by the number of shares for which this
Option is then exercised. In determining the Cash-Out Price, the value of
consideration other than cash shall be determined by a nationally recognized
investment banking firm selected by Grantee and reasonably acceptable to Issuer.
Grantee will cooperate with the valuation work of any investment banking firm
selected pursuant to this Section 7(c). Notwithstanding the termination of the
Option, Grantee will be entitled to exercise its rights under this Section 7(c)
if it has exercised such rights in accordance with the terms hereof prior to the
termination of the Option.

                  8. Registration Rights. (a) At any time and from time to time
within three years of date hereof, Grantee may by written notice (a
"Registration Notice") to Issuer request Issuer to register under the Securities
Act all or part of any Issuer Common Stock acquired hereunder and beneficially
owned by Grantee (collectively, the "Registrable Securities") in order to permit
the sale or other disposition of such securities pursuant to, at the option of
Grantee, (i) a shelf registration or (ii) a bona fide, firm commitment
underwritten public offering in which Grantee shall have the right, including
with respect to any takedown off the shelf, to select the managing underwriter,
which shall be reasonably acceptable to Issuer, and shall effect as wide a
distribution of such Registrable Securities as is reasonably practicable;
provided, however, that any such Registration Notice must relate to a number of
shares equal to at least 40% of the Option Shares.

                  (b) Issuer shall use reasonable best efforts to effect, as
promptly as practicable, the registration under the Securities Act of the
Registrable Securities requested to be registered in the Registration Notice and
to keep such registration statement current; provided, however, that (i) Grantee
shall not be entitled to more than an aggregate of two effective registration
statements hereunder and (ii) Issuer will not be required to file any such
registration statement during any period of time (not to exceed 60 days after a
Registration Notice in the case of clause (A) below or 120 days after a
Registration Notice in the case of clauses (B) and (C) below) when (A) Issuer is
in possession of material non-public information which it reasonably believes
would be detrimental to be disclosed at such time and, based upon the advice of
outside securities counsel to Issuer, such information would have to be
disclosed if a registration statement were filed at that time; (B) Issuer would
be required under the Securities Act to prepare audited financial statements for
any period in such registration statement; or (C) Issuer determines, in its

                                       6
<PAGE>   7
reasonable judgment, that such registration would interfere with any financing,
acquisition or other material transaction involving Issuer; provided that the
filing of such registration statement may not be delayed more than an aggregate
of 120 days after the Registration Notice. If the consummation of the sale of
any Registrable Securities pursuant to a registration statement therefor does
not occur, the provisions of this Section shall again be applicable to any
proposed registration thereafter, it being understood that Grantee shall not be
entitled to more than an aggregate of two effective registration statements
hereunder. Issuer will use reasonable best efforts to cause each such
registration statement to become effective, to obtain all consents or waivers of
other parties which are required therefor, and to keep such registration
statement effective for such period not in excess of 180 calendar days from the
day such registration statement first becomes effective as may be reasonably
necessary to effect such sale or other disposition. Issuer shall use reasonable
best efforts to cause any Registrable Securities registered pursuant to this
Section to be qualified for sale under the securities or blue sky laws of such
jurisdictions as Grantee may reasonably request and shall continue such
registration or qualification in effect in such jurisdictions; provided,
however, that Issuer shall not be required to qualify to do business in, or
consent to general service of process in, any jurisdiction.

                  (c) If Issuer effects a registration under the Securities Act
of Issuer Common Stock for its own account or for any other stockholders of
Issuer (other than on Form S-4 or Form S-8, or any successor form), it will
allow Grantee the right to participate in such registration with its Registrable
Securities, and such participation will not affect the obligation of Issuer to
effect demand registration statements for Grantee under this Section 8, except
that, if the managing underwriters of such offering advise Issuer in writing
that in their opinion the number of shares of Issuer Common Stock requested to
be included in such registration exceeds the number which can be sold in such
offering, Issuer will include that portion of the shares requested to be
included therein equal to the product obtained by multiplying (i) the number of
shares which the underwriter has informed the Issuer can be included in the
offering and (ii) the percentage obtained by dividing (x) the total number of
shares of Issuer Common Stock held by Grantee and (y) the total number of shares
of Issuer outstanding.

                  (d) The registration rights set forth in this Section are
subject to the condition that Grantee shall provide Issuer with such information
with respect to Grantee, the Registrable Securities, the plan for distribution
thereof, and such other information with respect to Grantee as, in the
reasonable judgment of counsel for Issuer, is necessary to enable Issuer to
include in an registration statement all material facts required to be disclosed
with respect to a registration hereunder.

                  (e) A registration effected under this Section shall be
effected at Issuer's expense, except for underwriting discounts and commissions
and the fees and expenses of Grantee's counsel, and Issuer shall provide to the
underwriters such documentation as such underwriters may reasonably require. In
connection with any registration, Grantee and Issuer agree to enter into an
underwriting agreement reasonably acceptable to each such party, in form and
substance customary for transactions of this type.

                                       7
<PAGE>   8
                  (f) In connection with a registration effected under this
Section 8, Issuer shall indemnify and hold harmless Grantee, its affiliates and
controlling persons and their respective officers, directors, agents and
representatives from and against any and all losses, claims, damages,
liabilities and expenses (including, without limitation, all out-of-pocket
expenses, investigation expenses, expenses incurred with respect to any
judgement and fees and disbursements of counsel and accountants) arising out of
or based upon any statements contained in, or omissions or alleged omissions
from, each registration statement (and related prospectus) filed pursuant to
this Section 8; provided, however, that Issuer shall not be liable in any such
proceeding to the extent such loss or expense arises out of or is based upon an
untrue statement contained in, or omissions or alleged omission from, such
registration statement or prospectus in reliance upon and in conformity with,
written information furnished to Issuer specifically for use in the preparation
thereof by Grantee.

                  (g) In connection with a registration effected under this
Section 8, Grantee shall indemnify and hold harmless Issuer, its affiliates and
controlling persons, and their respective officers, directors, agents and
representatives from and against any and all losses, claims, damages,
liabilities and expenses (including, without limitation, all out-of-pocket
expenses, investigation expenses, expenses incurred with respect to any
judgement and fees and disbursement of counsel and accountants) arising out of
or based upon any statements contained in, or omissions or alleged omissions
from, each registration statement (and related prospectus) filed pursuant to
this Section 8 that arises out of or is based upon an untrue statement contained
in, or omission or alleged omission from, such registration statement or
prospectus in reliance upon, and in conformity with, written information
furnished to Issuer specifically for use in the preparation thereof by Grantee.

                  9. Listing. If Issuer Common Stock or any other securities to
be acquired upon exercise of the Option are then listed on a national securities
exchange or national securities quotation system, Issuer, upon the request of
Grantee, will promptly file an application to list the shares of Issuer Common
Stock on such national securities exchange or national securities quotation
system and will use reasonable efforts to obtain approval of such listing as
promptly as practicable.

                  10.      Miscellaneous.

                  (a) Expenses. Except as otherwise provided in the Merger
Agreement, each of the parties hereto will pay all costs and expenses incurred
by it or on its behalf in connection with the transactions contemplated
hereunder, including fees and expenses of its own financial advisors, investment
bankers, accountants and counsel.

                  (b) Amendment. This Agreement may not be amended, except by an
instrument in writing signed on behalf of each of the parties.

                                       8
<PAGE>   9
                  (c) Extension; Waiver. Any agreement on the part of a party to
waive any provision of this Agreement, or to extend the time for performance,
will be valid only if set forth in an instrument in writing signed on behalf of
such party. The failure of any party to this Agreement to assert any of its
rights under this Agreement or otherwise will not constitute a waiver of such
rights.

                  (d) Entire Agreement; No Third-Party Beneficiaries. This
Agreement and the Merger Agreement (i) constitute the entire agreement, and
supersede all prior agreements and understandings, both written and oral,
between the parties with respect to the subject matter of this Agreement, and
(ii) are not intended to confer upon any person other than the parties any
rights or remedies in respect of this Agreement.

                  (e) Counterparts. This Agreement may be executed in two or
more counter parts, all of which shall be considered one and the same agreement
and shall become effective when two or more counterparts have been signed by
each of the parties and delivered to the other parties.

                  (f) GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF DELAWARE WITHOUT GIVING
EFFECT TO THE PRINCIPLES OF CONFLICTS OR CHOICE OF LAW THEREOF OR OF ANY OTHER
JURISDICTION.

                  (g) Notices. All notices and other communications hereunder

                                    ARTICLE I

<PAGE>   2
applicable) all of such Stockholder's Subject Shares in favor of the adoption of
the Merger Agreement and in favor of any other matter necessary for the
consummation of the transactions contemplated by the Merger Agreement and
considered and voted upon at such meeting or made the subject of such written
consent, as applicable. At any meeting of the stockholders of the Company called

                  Section 1.2  Irrevocable Proxy.

                  (a) Grant of Proxy. THE STOCKHOLDER HEREBY APPOINTS PARENT AND
ANY DESIGNEE OF PARENT, EACH OF THEM INDIVIDUALLY, SUCH STOCKHOLDER'S PROXY AND
ATTORNEY-IN-FACT PURSUANT TO THE PROVISIONS OF SECTION 212 OF THE DELAWARE
GENERAL CORPORATION LAW, WITH FULL POWER OF SUBSTITUTION AND RESUBSTITUTION, TO
VOTE OR ACT BY WRITTEN CONSENT WITH RESPECT TO SUCH STOCKHOLDER'S SUBJECT SHARES
IN ACCORDANCE WITH SECTION 1.1 HEREOF. THIS PROXY IS GIVEN TO SECURE THE
PERFORMANCE OF THE DUTIES OF SUCH STOCKHOLDER UNDER THIS AGREEMENT. THE
STOCKHOLDER AFFIRMS THAT THIS PROXY IS COUPLED WITH AN INTEREST AND SHALL BE
IRREVOCABLE. THIS PROXY SHALL REMAIN IN EFFECT THROUGH AND INCLUDING THE EARLIER
OF (A) THE EFFECTIVE TIME AND (B) SIXTY DAYS AFTER THE TERMINATION OF THE MERGER
AGREEMENT. THE STOCKHOLDER SHALL TAKE SUCH OTHER ACTION OR EXECUTE SUCH OTHER
INSTRUMENTS AS MAY BE NECESSARY TO EFFECTUATE THE INTENT OF THIS PROXY.

                  (b) Other Proxies Revoked. The Stockholder represents that any
proxies heretofore given in respect of such Stockholder's Subject Shares are not
irrevocable, and that all such proxies are hereby revoked.

                                   ARTICLE II

                  Section 2.1 Grant of Option. The Stockholder hereby grants to
Parent an irrevocable option (the "Option") to purchase such Stockholder's
Subject Shares on the terms and subject to the conditions set forth herein, in
exchange for the number of Ordinary Shares, pound sterling0.01 par value, of
Parent ("Parent Ordinary Shares") equal to the product of (a) the Exchange Ratio
(as such term is defined in the Merger Agreement), and (b) the number of Subject
Shares to be purchased upon any particular exercise of such Option (such product
being the "Option Consideration"), with the type and number of shares,
securities or other property subject to the Option, and the Option Consideration
payable therefor, being subject to adjustment as provided


                                        2
<PAGE>   3
herein. For purposes of this Agreement, the "Pre-Closing Average Price" used to
determine the Exchange Ratio shall be determined on the basis of the average of
the closing prices per Parent Ordinary Share during the ten consecutive trading
days ending on the second trading day prior to the Option Closing (as
hereinafter defined). In the event that the grant or exercise of the Option
shall result in liability to the Stockholder under Section 16(b) of the
Securities Exchange Act of 1934, as amended, Parent shall hold such stockholder
harmless for such liability (on an after-tax basis), subject to accuracy of the
information previously provided to Parent concerning recent stock transactions
by the Stockholder.

                  Section 2.2 Exercise of Option. Parent may exercise all or any
of the Option, in whole or in part, at any time or from time to time during the
period (the "Option Period") from and including the date hereof through and
including the earlier of (i) the Effective Time and (ii) sixty days after the
termination of the Merger Agreement. The purchase of any Subject Shares upon
exercise of an Option shall be subject to compliance with the HSR Act (as such
term is defined in the Merger Agreement), to the extent that the HSR Act is
applicable to such purchase. Notwithstanding the expiration of the Option
Period, Parent shall be entitled to purchase all Subject Shares in respect of
which an Option shall have been exercised prior to the expiration of the Option
Period, and the expiration of the Option Period shall not affect any rights
hereunder which by their terms do not terminate or expire prior to or as of such
expiration.

                  If Parent wishes to exercise an Option, it shall deliver to
the Stockholder (the "Selling Stockholder") a written notice to that effect
which specifies (i) the number of Subject Shares to be purchased from such
Selling Stockholder and (ii) a date not earlier than three business days nor
later than 20 business days from the date such notice is delivered for the
consummation of the purchase and sale of such Subject Shares (the "Option
Closing Date"); provided, however, that (x) if the consummation of the purchase
and sale of such Subject Shares (the "Option Closing") cannot be effected by
reason of any applicable judgment, decree, order, law or regulation, the period
of time that otherwise would run pursuant to this sentence shall run instead
from the date on which such restriction on consummation has expired or been
terminated and (y) without limiting the foregoing, if prior notification to or
approval of any regulatory authority is required in connection with such
purchase, Parent and the applicable Selling Stockholder shall promptly file the
required notice or application for approval and shall cooperate in the
expeditious filing of such notice or application, and the period of time that
otherwise would run pursuant to this sentence shall run instead from the date on
which any required notification period has expired or been terminated, any
required approval has been obtained and any requisite waiting period has expired
or been terminated. The place of the Option Closing shall be at the offices of
Reboul, MacMurray, Hewitt, Maynard & Kristol, 45 Rockefeller Plaza, New York,
New York 10111, and the time of the Option Closing shall be 10:00 a.m. (New York
Time) on the Option Closing Date.

                  Section 2.3 Parent and Delivery of Certificates, At any Option
Closing, Parent shall deliver to the Selling Stockholder a certificate or
certificates evidencing the Option Consideration payable in respect of the
Subject Shares to be purchased from such Selling

                                        3
<PAGE>   4
Stockholder at the Option Closing, and the Selling Stockholder shall deliver to
Parent such Subject Shares, free and clear of all liens and encumbrances, with
the certificate or certificates evidencing such Subject Shares being duly
endorsed for transfer by such Selling Stockholder and accompanied by all powers
of attorney and/or other instruments necessary to convey valid and unencumbered
title thereto to Parent, and shall assign to Parent (pursuant to a written
instrument in form and substance satisfactory to Parent) all rights that such
Selling Stockholder may have to require Company to register such Subject Shares
under the Securities Act of 1933, as amended (the "Securities Act"). Transfer
taxes, if any, imposed as a result of the exercise of an Option shall be borne
by the Selling Stockholder.

                  Section 2.4 Adjustment upon Changes in Capitalization, Etc. In
the event of any change in the capital stock of either the Company or Parent by
reason of a stock dividend, split-up, merger, recapitalization, combination,
exchange of shares, extraordinary distribution or similar transaction, the type
and number of shares, securities or other property subject to the Option, and
the Option Consideration payable therefor, shall be adjusted appropriately, and
proper provision shall be made in the agreements governing such transaction, so
that (a) Parent shall receive upon exercise of any Option the number and class
of shares, securities or property that Parent would have received in respect of
the applicable Selling Stockholder's Subject Shares if the Option had been
exercised immediately prior to such event relating to the Company or the record
date therefor, as applicable, and (b) the applicable Selling Stockholder shall
receive upon exercise of any Option granted by such Selling Stockholder the
number and class of shares, securities or other property that such Selling
Stockholder would have received in respect of such Selling Stockholder's Subject
Shares if the Option had been exercised immediately prior to such event relating
to Parent or the record date therefor, as applicable.

                  Section 3.1 Certain Representations and Warranties of the

                           (b)      Due Authorization.  Such Stockholder has all
requisite power and authority to enter into this Agreement and to consummate the
transactions contemplated hereby. The execution and delivery of this Agreement

moratorium and similar laws affecting creditors' rights generally and to general
principles of equity.

                           (c)      No Conflicts.  The execution and delivery of
this Agreement do not, and, subject to compliance with the HSR Act, to the
extent applicable, the consummation of the transactions contemplated hereby and
compliance with the provisions of this Agreement will not, conflict with, result
in a breach or violation of or default (with or without notice or lapse of time
or both) under, or give rise to a material obligation, a right of termination,
cancellation, or acceleration of any obligation or a loss of a material benefit
under, or require notice to or the consent of any person under any agreement,
instrument, undertaking, law, rule, regulation, judgment, order, injunction,
decree, determination or award binding on such Stockholder, other than any such

individually or in the aggregate would not (i) impair the ability of such
Stockholder to perform such Stockholder's obligations under this Agreement or
(ii) prevent or delay the consummation of any of the transactions contemplated
hereby.

                           (d)      Purchase Not for Distribution.  The Parent
Ordinary Shares to be acquired by such Stockholder upon Parent's exercise of an
Option shall be so acquired without a view to the public distribution thereof
and such shares shall not be transferred or otherwise disposed of except in a
transaction registered or exempt from registration under the Securities Act and
in compliance with applicable state securities laws.

                  Section 3.2 Representations and Warranties of Parent. Parent
hereby represents and warrants to the Stockholder that:

                           (a)      Due Authorization.  Parent has all requisite
corporate power and authority to enter into this Agreement and to consummate the
transactions contemplated hereby. The execution and delivery of this Agreement

in accordance with its terms, subject to applicable bankruptcy, insolvency,
fraudulent conveyance, reorganization, moratorium and similar laws affecting
creditors' rights generally and to general principles of equity.

                           (b)      No Conflicts.  The execution and delivery of
this Agreement do not, and, subject to compliance with the HSR Act, to the
extent applicable, the consummation of the transactions contemplated hereby and
compliance with the provisions of this Agreement will not, conflict with, result

under, or require notice to or the consent of any person under any agreement,
instrument, undertaking, law, rule, regulation,



                                        5
<PAGE>   6
judgment, order, injunction, decree, determination or award binding on Parent,
other than any such conflicts, breaches, violations, defaults, obligations,
rights or losses that individually or in the aggregate would not (i) impair the
ability of Parent to perform its obligations under this Agreement or (ii)
prevent or delay the consummation of any of the transactions contemplated
hereby.

                           (c)      Purchase Not for Distribution.  The Option
and the Subject Shares to be acquired upon exercise of the Option are being and
shall be acquired by Parent without a view to the public distribution thereof
and neither the Option nor any Subject Shares to be acquired upon exercise

                                   ARTICLE IV

                Section 4.1 Certain Covenants of the Stockholder.

                           (a)      Restriction on Transfer of Subject Shares,
Proxies and Noninterference. No Stockholder shall directly or indirectly: (i)
except pursuant to the terms of this Agreement or the Merger Agreement, offer
for sale, sell, transfer, tender, pledge, encumber, assign or otherwise dispose
of, or enter into any contract, option or other arrangement or understanding
with respect to or consent to the offer for sale, sale, transfer, tender,
pledge, encumbrance, assignment or other disposition of, any or all of such
Stockholder's Subject Shares; (ii) except pursuant to the terms of this
Agreement, grant any proxies or powers of attorney, deposit any of such
Stockholder's Subject Shares into a voting trust or enter into a voting
agreement with respect to any of such Stockholder's Subject Shares; or (iii)
take any action that would make any representation or warranty contained herein
untrue or incorrect or have the effect of impairing the ability of such
Stockholder to perform such Stockholder's obligations under this Agreement or
preventing or delaying the consummation of any of the transactions contemplated
hereby.

                           (b)      Restrictions on Transfer of Parent Ordinary
Shares. Prior to the first anniversary of the Effective Time or the second
anniversary of any Option Closing, no Stockholder shall sell, assign or
otherwise dispose of any of the Parent Ordinary Shares received by such
Stockholder pursuant to the Merger or such Option Closing, as the case may be,
except (i) pursuant to an effective registration statement under the Securities
Act, (ii) in conformity with the volume limitations and other provisions of SEC
Rule 145, or (iii) in a transaction which, in the opinion of counsel reasonably
satisfactory to Parent, is not required to be registered under the Securities
Act. The Stockholder understands and acknowledges that, except as provided in
Section 4.2, Parent shall not be required to maintain the effectiveness of any
registration statement under the Securities Act for the purpose of facilitating
the resale of any Parent Ordinary Shares by such Stockholder. In the event of a
sale, assignment or other disposition by any Stockholder of Parent Ordinary
Shares pursuant to SEC Rule 145, such Stockholder shall supply Parent with



                                        6
<PAGE>   7
evidence of compliance with such Rule, in the form of a letter in the form of
Annex I hereto and the opinion of counsel referred to above. The Stockholder
understands and acknowledges that Parent may instruct its transfer agent to
withhold the transfer of any Parent Ordinary Shares disposed of by any
Stockholder, but that (provided such transfer is not prohibited by any other
provision of this Agreement) upon receipt of such evidence of compliance, Parent
shall cause the transfer agent to effectuate the transfer of the Parent Ordinary
Shares sold as indicated in such letter.

                           (c)      Tax Treatment.  No Stockholder shall or
shall permit any affiliate of such Stockholder to take any position on any
federal, state or local income tax return, or take any other action or reporting
position, that is inconsistent with the treatment of the Merger as a
reorganization within the meaning of Section 368(a) of the Internal Revenue Code
of 1986, as amended (the "Code"), or with the representations made in this
Agreement, unless otherwise required pursuant to a "determination" (as defined
in Section 1313(a)(1) of the Code).

                  Section 4.2 Registration Rights. (a) On the terms and subject
to the conditions set forth in this Section 4.2, within 30 days after the
earlier of the Effective Time (as defined in the Merger Agreement) and the first
Option Closing, Parent shall file, and shall thereafter use its reasonable best
efforts to cause to become and remain effective, for so long as the Parent
Ordinary Shares held by the Stockholder continue to be Registrable Securities
(as hereinafter defined), a registration statement registering for purposes of
the Securities Act the resale of all Registrable Securities held by the
Stockholder (the "Registration Statement"). For so long as Parent is required to
cause the Registration Statement to remain in effect, Parent shall use its
reasonable best efforts to cause the Parent Ordinary Shares to be (x) registered
or qualified (to the extent not exempt from such registration or qualification)
for sale under the blue sky laws of such states as any Stockholder may
reasonably request (provided that Parent shall not be required to qualify to do
business in, or consent to general service of process in, any jurisdiction by
reason thereof) and (y) listed on a national securities exchange or accepted for
quotation on the National Association of Securities Dealers Automated Quotation
System.

                           (b)      The obligations of Parent hereunder to file
the Registration Statement and to maintain its effectiveness may be suspended
for one or more periods of time not exceeding 90 calendar days in the aggregate
if the Board of Directors of Parent shall have determined that the filing of the
Registration Statement or the maintenance of its effectiveness would require
disclosure of nonpublic information that would materially and adversely affect
Parent or would materially interfere with any financing, acquisition or other
transaction involving Parent. The preparation and filing of the Registration
Statement, and any sale covered thereby, will be at Parent's expense, except for
underwriting discounts or commissions, brokers' fees and the fees and
disbursements of counsel for any Stockholder related thereto.

                           (c)      The Stockholder shall provide all
information reasonably requested by Parent for inclusion in the Registration
Statement and any related prospectus (a "Prospectus"). In connection with the
sale or other disposition of Registrable Securities to be effected pursuant


                                        7
<PAGE>   8
to the Registration Statement, Parent and the Stockholder will provide each
other and any underwriter with customary representations, warranties, covenants,
indemnification and contribution.

                           (d)      The Stockholder shall use its reasonable
best efforts to cause, and to cause any underwriters of any sale or other
disposition to cause, any sale or other disposition of Parent Ordinary Shares
pursuant to the Registration Statement to be effected on as widely a distributed
basis as practicable.

                           (e)      For purposes of this Agreement, the term
"Registrable Securities" means Parent Ordinary Shares acquired by any
Stockholder as a result of the conversion of shares of Common Stock pursuant to
the Merger or as Option Consideration at any Option Closing; provided, however,
that Registrable Securities will cease to be Registrable Securities when and to
the extent that (i) a registration statement covering such Registrable
Securities has been declared effective under the Securities Act and such
Registrable Securities have been disposed of pursuant to such effective
registration statement, (ii) one year has elapsed since the acquisition of such
Registrable Securities by the applicable Stockholder, or (iii) such Registrable
Securities are sold or transferred by a Stockholder otherwise than to another
Stockholder. The Stockholder shall promptly notify Parent when any of such
Stockholder's Parent Ordinary Shares shall have ceased to be Registrable
Securities.

                           (f)      Parent will notify the Stockholder as
promptly as practicable of (i) any request by the SEC or any other federal or
state governmental authority for amendments or supplements to the Registration
Statement or any Prospectus or for additional information, (ii) 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, (iii) 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, and (iv) the occurrence of any
event which makes any statement made in the Registration Statement or a
Prospectus untrue in any material respect or which requires the making of any
changes in the Registration Statement or a Prospectus or other documents so that
(A) 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
(B) in the case of a Prospectus, 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, in light of the circumstances under
which they were made, not misleading. The Stockholder will be deemed to have
agreed that, upon receipt of any notice from Parent of the occurrence of any
event of the kind described in the immediately preceding sentence, such
Stockholder will discontinue offers, sales and other dispositions of Registrable
Securities covered by the Registration Statement or a Prospectus until such
Stockholder's receipt of the copies of a supplemented or amended Prospectus or
until such Stockholder is advised in writing by Parent that the use of the
applicable



                                        8
<PAGE>   9
Prospectus may be resumed and has received copies of any additional or
supplemental filings that are incorporated or deemed to be incorporated by
reference in such Prospectus.

                  Section 5.1 Fees and Expenses. Except to the extent otherwise

except by an instrument in writing signed on behalf of each of the parties
hereto.

                  Section 5.3 Extension Waiver. Any agreement on the part of a
party to waive any provision of this Agreement, or to extend the time for any
performance hereunder, shall be valid only if set forth in an instrument in
writing signed on behalf of such party. The failure of any party to this
Agreement to assert any of its rights under this Agreement or otherwise shall
not constitute a waiver of such rights.

                  Section 5.4 Legend. The Stockholder acknowledges and agrees
that the legend set forth below shall be placed on certificates representing
Parent Ordinary Shares received by such Stockholder in connection with the
Merger or any Option Closing, or held by a transferee thereof of such
Stockholder, which legend shall be removed by delivery of substitute
certificates upon receipt the first anniversary of the Effective Time or the
second anniversary of such Option Closing, as the case may be, or upon (a) the
earlier sale of such Parent Ordinary Shares (i) pursuant to an effective
registration statement under the Securities Act or (iii) in conformity with the
provisions of SEC Rule 145, or (b) the receipt by Parent of an opinion in form
and substance reasonably satisfactory to Parent from independent counsel
reasonably satisfactory to Parent to the effect that such legend is no longer
required for purposes of the Securities Act.

                  There shall be placed on the certificates for Parent Ordinary
Shares issued to the Stockholder, or any substitutions therefor, a legend
stating in substance:

         "THE SHARES REPRESENTED BY THIS CERTIFICATE WERE ISSUED IN A
TRANSACTION TO WHICH RULE 145 PROMULGATED UNDER THE SECURITIES ACT OF 1933
APPLIES. THE SHARES HAVE NOT BEEN ACQUIRED BY THE HOLDER WITH A VIEW TO, OR FOR
RESALE IN CONNECTION WITH, ANY DISTRIBUTION THEREOF WITHIN THE MEANING OF THE
SECURITIES ACT OF 1933. THE SHARES MAY NOT BE SOLD, PLEDGED OR OTHERWISE
TRANSFERRED EXCEPT IN ACCORDANCE WITH THE REGISTRATION REQUIREMENTS OF THE
SECURITIES ACT OF 1933 OR AN EXEMPTION THEREFROM."

      AMDOCS LIMITED TO ACQUIRE INTERNATIONAL TELECOMMUNICATION DATA SYSTEMS,
      INC.

      INDUSTRY LEADER IN CUSTOMER CARE AND BILLING SOLUTIONS EXPANDS OUTSOURCING
      CAPABILITIES

      ST. LOUIS and STAMFORD, Conn.-- Sept. 6, 1999 --Amdocs Limited (NYSE: DOX
      news), a global leader in customer care, billing and order management
      solutions for the telecom industry, and International Telecommunication
      Data Systems, Inc. (NASDAQ: ITDS - news), a leading provider of
      outsourcing and service bureau solutions to telecom companies, today
      jointly announced an agreement for Amdocs Limited to acquire International
      Telecommunication Data Systems, Inc. (ITDS) for approximately $182 million
      in Amdocs shares.

      The combination expands the scope of Amdocs' solution services through the
      enhancement of outsourcing capabilities for telecom customer care and
      billing operations. Amdocs expects the transaction to be accretive to its
      earnings immediately upon close of the transaction.

      "The deal brings together powerful, scalable customer care and billing
      systems from Amdocs with proven billing outsourcing capabilities from
      ITDS," said Avi Naor, President and Chief Executive Officer of Amdocs
      Management Limited. "Amdocs currently supports its customer care and
      billing customers with a rich services offering including customization,
      implementation, system integration and ongoing support. With the
      acquisition of ITDS, we will be expanding our services capabilities in the
      outsourcing area."

      Naor added, "In our target market, which comprises high-end and mid-tier
      providers of wireless, wireline, data and convergence services, we are
      witnessing demand for outsourcing as well as in-house solutions. The ITDS
      acquisition allows Amdocs to expedite the expansion of our outsourcing
      services offering. In addition, ITDS' focus on establishing long-term
      relationships with their customers is consistent with our business model
      and the high visibility of our business performance."

      "The deal is a good fit for both companies, complementing our respective
      capabilities," said Lewis Bakes, Chairman of the Board of ITDS. "The
      combined company will expand the total market currently addressed by
      Amdocs and ITDS, based on a set of systems and outsourcing capabilities
      that is unmatched in the industry. Our collective scalable software and
      data processing solutions will be very attractive to carriers and
      resellers, both domestically and internationally."

      Under the terms of the agreement, Amdocs will acquire all outstanding
      shares of ITDS in a stock-for-stock merger transaction that will be
      accounted for using the purchase accounting method under U.S. GAAP rules.
      In the merger, each ITDS common share will be exchanged for a number of
<PAGE>   2
      Amdocs Ordinary Shares equal to $10.50 divided by the ten-day average
      closing price of the Amdocs shares immediately prior to the completion of
      the merger, subject to a maximum exchange ratio of .4603 and a minimum
      exchange ratio of .3717. In addition, Amdocs will convert ITDS options to
      Amdocs options according to the same exchange ratio. To complete the
      transaction, Amdocs will file a registration statement for the issuance of
      approximately 6.6 million shares, based on a recent closing price of
      $27.50 for Amdocs' shares. Closing of the transaction is subject to the
      approval of ITDS shareholders and required regulatory approvals as well as
      certain other customary closing conditions. Amdocs expects the transaction
      to close by the end of December 1999.
