Saville Systems PLC
IDA Business Park
Dangan
Galway, Ireland



                                                                   July 30, 1999


Dear Shareholder:


    Holders of record of ordinary shares, nominal value U.S.$0.0025 per share,
of Saville Systems PLC, a public limited company incorporated under the laws of
Ireland ("Saville"), are cordially invited to attend a meeting (the "Scheme
Ordinary Meeting") convened by direction of the High Court of Ireland and an
extraordinary general meeting (the "Extraordinary General Meeting"), at which
shareholders will all be asked to vote on the proposals pursuant to which ADC
Telecommunications, Inc., a Minnesota corporation ("ADC"), will become the owner
of 100% of Saville's ordinary shares and deferred shares (the "Acquisition")
pursuant to the scheme of arrangement (the "Scheme") set out in an agreement,
dated as of June 19, 1999, between Saville and ADC (as amended on June 30, 1999,
the "Acquisition Agreement"). In addition, holders of record of deferred shares,
nominal value IRL1.00 per share, of Saville are cordially invited to attend a
meeting (the "Scheme Deferred Meeting") convened by direction of the High Court
at which they will be asked to vote on the Scheme.


    Upon completion of the Acquisition:

    - all issued and outstanding ordinary shares of Saville will be cancelled
      and the holders thereof will receive 0.358 share (the "Ordinary Share
      Allotment Ratio") of ADC common stock in consideration for each ordinary
      share so cancelled;

    - all issued and outstanding deferred shares of Saville will be cancelled
      and the holders thereof will receive 0.027 share (the "Deferred Share
      Allotment Ratio") of ADC common stock in consideration for each deferred
      share so cancelled;

    - all outstanding options to purchase ordinary shares of Saville will be
      assumed by ADC and converted into options to purchase a number of shares
      of ADC common stock determined by multiplying the number of ordinary
      shares subject to the Saville options by the Ordinary Share Allotment
      Ratio. The terms and conditions of the ADC options will be the same as the
      terms and conditions of the Saville options, except that the exercise
      price will be appropriately adjusted and, in accordance with the terms of
      the Saville options, the ADC options will be fully vested upon the change
      in control of Saville; and


    - upon reduction of the share capital of Saville created by the cancellation
      of the ordinary shares and the deferred shares as described above, the
      share capital of Saville will be increased by U.S.$98,034.8775 and
      IRL30,000 by the creation of 39,213,951 new ordinary shares and 30,000 new
      deferred shares, which will be allotted and issued, credited as fully
      paid, to ADC, and Saville will become a wholly owned subsidiary of ADC.


    Our Board of Directors has determined by a unanimous vote of disinterested
directors and by a unanimous vote of all directors that the terms of the
Acquisition Agreement and the Scheme are fair to, and in the best interests of,
our shareholders. In making this decision, the Board of Directors considered,
among other things, the written opinion, dated June 18, 1999, of Morgan Stanley
& Co. Incorporated, to the effect that, as of the date of the opinion and based
upon and subject to certain matters stated therein, the Ordinary Share Allotment
Ratio, as set forth in the Scheme, is fair, from a financial point of view, to
our shareholders. In addition, our Board of Directors has determined that the
Deferred Share Allotment Ratio as set forth in the Scheme, is fair, from a
financial point of view, to our shareholders. As a result of the foregoing, our
Board of Directors has approved the Acquisition Agreement and the Scheme.

           ordinary shares shall be subject to the terms of the Scheme and the
           holder or holders of such ordinary shares shall be bound by the
           Scheme accordingly.



       (c) If any ordinary shares, other than Scheme Shares, are allotted or
           issued to any person (a "new member") (other than to ADC or any

           may appoint any person to execute a form of transfer on behalf of the
           new member in favor of ADC and to agree for and on behalf of the new
           member to become a member of ADC. Pending the registration of ADC as
           the holder of any share to be transferred pursuant to this Article,
           ADC shall be empowered to appoint a person nominated by the Directors
           to act as attorney on behalf of each holder of the share in
           accordance with such directions as ADC may give in relation to any
           dealings with or disposal of such share (or any interest therein),
           exercising any rights attached thereto or receiving any distribution

           registered holders of such share shall exercise all rights attaching
           thereto in accordance with the directions of ADC but not otherwise."

other things, that where the intended procedure is being adopted, Saville must
send to all shareholders, along with notices summoning the necessary meetings, a
statement explaining the effect of the scheme being proposed and describing any
material interests of the directors of Saville (in their capacities as
directors, shareholder or creditors) and any effects which the Scheme will have
upon them which are different from the effects which it will have on others
affected by the Scheme.


    For the purpose of complying with the securities laws of the United States
(where Saville's ordinary shares in the form of American Depositary Shares
("ADSs") evidenced by American Depositary Receipts ("ADRs") are traded on the
Nasdaq National Market), this proxy statement has been prepared in accordance
with the requirements of those laws and the requirements of the U.S. Securities
and Exchange Commission. The Scheme itself is set out in Annex B. The proxy
statement contains detailed information as required by the laws of the United
States as to the Scheme which is proposed and the arrangements and circumstances
surrounding it. Saville advises shareholders that the whole of the document
should therefore be treated by them as the statement for the purposes of Section
202 and it urges them to study it if they wish to understand both what is being
proposed and the circumstances in which the proposal is made.


    For people accustomed to reading less detailed material in connection with
proposals of this kind and who wish to read only a more limited quantity of
material, Saville suggests that they study at least the following sections
particularly:


    QUESTIONS AND ANSWERS ABOUT THE ACQUISITION AND THE SCHEME (page 1)
    SUMMARY (which explains the contents of the whole document) (page 4)
    RISK FACTORS (page 23)
    THE ACQUISITION (page 35)
    THE ACQUISITION AGREEMENT AND THE SCHEME (page 51)
    DESCRIPTION OF ADC CAPITAL STOCK (page 63)
    COMPARISON OF SHAREHOLDER RIGHTS (page 64)



and those interested in studying the effects of the Scheme and the arrangements
generally upon directors should study particularly the text headed INTERESTS OF
CERTAIN PERSONS IN THE ACQUISITION on page 43; (this forms part of the section
THE ACQUISITION referred to above).


    SAVILLE STRESSES, HOWEVER, THAT THOSE WISHING TO CONSIDER THE MATERIAL BEING
SENT TO THEM FOR THE PURPOSES OF SECTION 202 SHOULD STUDY THE WHOLE OF THIS
DOCUMENT, INCLUDING THE ANNEXES HERETO.

           QUESTIONS AND ANSWERS ABOUT THE ACQUISITION AND THE SCHEME

Q: WHAT IS THE ACQUISITION?


A:  On June 19, 1999, Saville entered into an Acquisition Agreement with ADC
whereby, pursuant to the Scheme, Saville will become a wholly owned subsidiary
of ADC. 0.358 share (the "Ordinary Share Allotment Ratio") of ADC common stock
will be issued to the holders of Saville's ordinary shares in consideration for
the cancellation of each outstanding ordinary share, which represents a premium
of approximately 14.9% (based on the closing price of the ADC common stock as of
June 18, 1999) over the closing price for the American Depositary Receipts
("ADRs") evidencing American Depositary Shares ("ADSs") (which in turn represent
ordinary shares) on the Nasdaq National Market on June 18, 1999, the last
trading day prior to the public announcement of the proposed Acquisition.


    In addition, pursuant to the Acquisition Agreement and the Scheme, each
outstanding deferred share of Saville will be cancelled and the holders thereof
will receive 0.027 share (the "Deferred Share Allotment Ratio") of ADC common
stock and all options to purchase ordinary shares of Saville outstanding on the
closing date of the Acquisition will be assumed by ADC and will be converted on
the basis of the Ordinary Share Allotment Ratio into options to purchase shares
of ADC common stock.

    Following the consummation of the Acquisition, Saville's shareholders will
no longer own any interest in Saville.

Q: WHAT ARE THE MEETINGS?

A:  The Scheme Ordinary Meeting and the Scheme Deferred Meeting are meetings of
the holders of ordinary shares and the holders of deferred shares, respectively,
each of which has been convened by the direction of the High Court for the
purpose of considering, and, if thought fit, approving the Scheme. The
Extraordinary General Meeting for holders of ordinary shares has been convened
by Saville for the purpose of considering and, if thought fit, approving the
reduction of Saville's capital and certain other matters proposed in, or
incidental to, the Scheme.

Q: WHEN AND WHERE WILL THE MEETINGS TAKE PLACE?


A:  The Scheme Ordinary Meeting, the Scheme Deferred Meeting and the
Extraordinary General Meeting are scheduled to take place at 10:00 a.m., 10:05
a.m. and 10:10 a.m., respectively, local time (or, in each case, as soon
thereafter as the relevant preceding Meeting has concluded or been adjourned),
on August 31, 1999 at The Great Southern Hotel, Shannon, County Clare, Ireland.


Q: CAN I ATTEND THE MEETINGS?

A:  Holders of record of ordinary shares are entitled to attend and vote at the
Scheme Ordinary Meeting and the Extraordinary General Meeting either in person
or by proxy. Holders of record of deferred shares are entitled to attend and
vote at the Scheme Deferred Meeting either in person or by proxy.

Q: WHAT DO SHAREHOLDERS NEED TO DO NOW?


A:  Whether or not you intend to attend the relevant Meeting(s) in person, you
should indicate on the relevant proxy card(s) how you wish to vote and sign and
return the card(s) in the enclosed return envelope as soon as possible so that,
if you do not attend personally, you will be represented by proxy at the
relevant Meeting(s).


Q: WHAT DO HOLDERS OF ADSS NEED TO DO TO VOTE THEIR SHARES?


A:  Holders of ADSs are not entitled to attend the Meetings. Saville has made
arrangements with the Bank of New York, as Depositary for the ADRs, so that
Saville ADR holders will receive from the Depositary materials explaining the
Acquisition. These materials will include forms of instructions to the
Depositary for voting the ordinary shares represented by the ADSs at the Scheme
Ordinary Meeting and the Extraordinary General Meeting. These materials will
also advise ADR holders who wish to attend the Scheme Ordinary Meeting and the
Extraordinary General Meeting to take steps to present their ADRs to the
Depositary for cancellation and delivery of ordinary shares so as to become
record holders of ordinary shares prior to those Meetings.

<PAGE>

    Under the terms of Saville's agreement with the Depositary, Saville shall be
deemed to have received a proxy to vote those ordinary shares represented by
ADSs where the holders do not instruct the Depositary how to vote, and Saville
intends to vote all such ordinary shares represented by ADSs FOR the proposals
presented at the Meetings.


Q: WHAT DO SHAREHOLDERS WHO HAVE SENT IN A PROXY CARD DO IF THEY WANT TO CHANGE
  THEIR VOTE?

A:  Just mail a later-dated, signed proxy card or other instrument revoking your
proxy to be received by the time as set forth herein to the offices of Saville's
Registrar or to the registered office of Saville as described herein.
Shareholders who are record holders of ordinary shares or deferred shares may
also change their vote by attending the relevant Meeting and voting in person.

Q: IF MY ADRS ARE HELD IN "STREET NAME" BY MY BROKER, WILL MY BROKER VOTE MY
  SHARES FOR ME?


A:  Your broker will instruct the Depositary how to vote your ordinary shares
represented by ADSs for you only if you provide instructions on how to vote. You
should instruct your broker how to vote, following the directions provided by
your broker. Without instructions, your broker will not be able to instruct the
Depositary how to vote your ordinary shares represented by ADSs. As noted above,
under the terms of Saville's agreement with the Depositary, Saville shall be
deemed to have received a proxy to vote those ordinary shares represented by
ADSs where the holders do not instruct the Depositary how to vote, including
those ADRs in respect of which instructions are not received because a broker
has not received appropriate instructions on how to vote. Saville intends to
vote all such ordinary shares represented by ADSs FOR the proposals presented at
the Meetings.


Q: SHOULD I SEND IN MY SHARE CERTIFICATES OR ADRS NOW?

A:  No. If the Acquisition is consummated, you will receive written instructions
for exchanging your share certificates or ADRs.

Q: WHEN AND WHERE WILL THE HIGH COURT SANCTION HEARING TAKE PLACE?


A:  At this time, it is not possible to say on what date the hearing will take
place but it is expected to take place in October. The hearing will take place
at the Four Courts, Dublin 7, Ireland.


Q: CAN I ATTEND THE HIGH COURT SANCTION HEARING?


A:  All holders of ordinary shares and of deferred shares are entitled to attend
and be heard at the hearing in person or through a professional lawyer.


Q: WHEN IS THE ACQUISITION EXPECTED TO BE CONSUMMATED?


A:  We are working toward consummating the Acquisition as quickly as possible
following shareholder approval. However, in addition to shareholder approval, we
must also obtain judicial and regulatory approvals or exemptions, including
sanctioning of the Scheme by the High Court and certain U.S., Irish and other
antitrust approvals or waivers, among others. We hope to obtain the required
approvals or exemptions in time to consummate the Acquisition by October 31,
1999; however, it is possible that the Acquisition will not be completed until a
later date.


Q: WHAT ARE THE U.S. FEDERAL TAX CONSEQUENCES OF THE ACQUISITION ARRANGEMENT TO
  ME?

A:  Your receipt of shares of ADC common stock that are delivered to you in
consideration for the cancellation of your ordinary shares (or your ADSs)
pursuant to the Scheme will not be taxable in the United States.

                                       2
<PAGE>
Q: WHAT ARE THE IRISH TAX CONSEQUENCES OF THE ACQUISITION TO ME?


A:  The receipt of shares of ADC common stock in consideration for the
cancellation of ordinary shares or deferred shares will not give rise to Irish
capital gains tax.



    Saville and ADC intend to make an application to the Irish tax authorities
to obtain a ruling that the assumption of Saville options by ADC and their
conversion into ADC options is not a taxable event under Irish law. Saville and
ADC cannot predict whether such a ruling will be obtained.


Q: WHO CAN HELP ANSWER MY QUESTIONS?

A:  For additional information about the Acquisition, including information
about how to complete and return your proxy card, please contact Saville's
Investor Relations Department in the United States at 781-270-6500. For
additional information about ADC, please contact its Investor Relations
Department at 612-946-3630.

    Saville provides innovative, convergent customer care and billing solutions
to service providers in the global telecommunications and energy industries.
Saville offers products and services designed to enable telecommunications and
energy service providers to bring new service offerings to market quickly, and
to bill accurately and reliably for multiple services on one convergent invoice.


ADC TELECOMMUNICATIONS, INC.

    ADC is a global supplier of voice, video and data systems for telephone,
cable television, Internet, broadcast, wireless and private communications
networks. ADC's systems enable local access and high-speed transmission of
communications services from providers to consumers and businesses over
fiber-optic, copper, coaxial and wireless media.


THE ACQUISITION AGREEMENT AND THE SCHEME (PAGE 51)



    The Scheme and the Acquisition Agreement provide that, among other things,
all issued and outstanding ordinary shares of Saville will be cancelled and the
holders thereof will receive 0.358 share of ADC common stock in consideration
for each ordinary share so cancelled, and all issued and outstanding deferred
shares will be cancelled and the holders thereof will receive 0.027 share of ADC
common stock in consideration for each deferred share so cancelled. Upon
reduction of Saville's capital by the cancellation of the ordinary shares and
the deferred shares, the share capital of Saville will be increased by
U.S.$98,034.8775 and IRL30,000 by the creation of 39,213,951 new ordinary shares
and 30,000 new deferred shares, which will be allotted and issued, credited as
fully paid, to ADC. As a result of the Acquisition, Saville will become a wholly
owned subsidiary of ADC.



    In addition, the Saville options will be assumed by ADC and converted into
options to acquire the number of whole shares of ADC common stock equal to the
number of ordinary shares that were issuable upon exercise of the Saville option
immediately prior to the effective time of the Acquisition multiplied by the
Ordinary Share Allotment Ratio, rounded down to the nearest whole number of
shares of ADC common stock. The per share exercise price of shares of ADC common
stock issuable upon exercise of these ADC options will be equal to the exercise
price per share at which the Saville option was exercisable immediately prior to
the effective time divided by the Ordinary Share Allotment Ratio, rounded up to
the nearest whole cent. After conversion, the other terms and conditions of the
ADC options will be the same as the terms and conditions of the Saville options,
except that, in accordance with the terms of the Saville options, the ADC
options will be fully vested.

OUR REASONS FOR THE ACQUISITION (PAGE 36)


    We believe that the Acquisition, including the Ordinary Share Allotment
Ratio and the Deferred Share Allotment Ratio, is fair to, and in the best
interests of, our shareholders. We believe that Saville will be more competitive
as a result of economies of scale and synergies realized as a subsidiary of ADC,
and that the operations of the combined company will be better able to serve the
needs of Saville's customers. In addition, we believe that the combined company
will be better able to take advantage of marketing opportunities worldwide. We
believe the Acquisition will enable our shareholders to take advantage of this
opportunity by receiving an attractive price for their ordinary shares and
deferred shares.


OUR RECOMMENDATION TO SHAREHOLDERS (PAGES 32, 36 AND 38)


    Our Board of Directors believes that the Acquisition is in the best
interests of our shareholders and recommends that shareholders vote FOR approval
of the Scheme, the reduction of Saville's capital and other matters to be
proposed at the Meetings.


WHAT YOU WILL RECEIVE (PAGES 51 AND 54)


    Following consummation of the Acquisition:

    - each holder of ordinary shares (including ordinary shares represented by
      ADSs) will receive 0.358 share of ADC common stock in consideration for
      each ordinary share (or ADS representing one ordinary share) owned by such
      shareholder;

    - each holder of deferred shares will receive 0.027 share of ADC common
      stock in consideration for each deferred share owned by such shareholder;
      and

    - holders of Saville options will receive ADC options as described herein.


THE MEETINGS (PAGE 30)



    The Scheme Ordinary Meeting, the Scheme Deferred Meeting and the
Extraordinary General Meeting are being held at The Great Southern Hotel,
Shannon, County Clare, Ireland, on August 31, 1999 and are scheduled for 10:00
a.m., 10:05 a.m. and 10:10 a.m., local time, respectively (or, in each case, as
soon thereafter as the relevant preceding Meeting has been concluded or
adjourned). At each of the Scheme Ordinary Meeting and the Scheme Deferred
Meeting, shareholders of the relevant class will be asked to approve the Scheme.
At the Extraordinary General Meeting, shareholders will be asked to approve the
reduction of Saville's capital and certain other matters proposed in, or related
to, the Scheme.



SHAREHOLDERS ENTITLED TO VOTE (PAGE 31)



    Each holder of record of ordinary shares is entitled to vote either in
person or by proxy at the Scheme Ordinary Meeting and will be entitled at that
Meeting to one vote for every ordinary share held by him. Voting will be by way
of a poll.



    Lawrence Barker, John J. Boyle III, Michael Durance, Susan Ernst, Eric
Fredine, Christopher Hanson and Robin Winn (the "Excluded Officers"), each an
executive officer of Saville, have entered into employment agreements with ADC
pursuant to which they will receive, among other things, options to purchase
shares of ADC common stock. See "The Acquisition--Interests of Certain Persons
in the Acquisition". Accordingly, the interests of the Excluded Officers, each
of whom owns ADSs, differ or may differ from those of other persons owning
ordinary shares, and the Excluded Officers have therefore agreed to instruct the
Depositary not to exercise the voting rights attaching to the ordinary shares
represented by the ADSs owned by them and have agreed to be bound by the Scheme
in respect of those shares.


                                       5
<PAGE>

    Each holder of record of deferred shares, other than John J. Boyle III, is
entitled to vote either in person or by proxy at the Scheme Deferred Meeting and
will be entitled at that meeting to one vote for every deferred share held by
him. Voting will be by way of a poll. John J. Boyle III has entered into certain
employment and other agreements with ADC. See "The Acquisition--Interests of
Certain Persons in the Acquisition." As a result, Mr. Boyle, who owns deferred
shares, will not be entitled to vote at the Scheme Deferred Meeting but has
agreed to be bound by the Scheme in respect of those shares.



    Each holder of record of ordinary shares is entitled to vote in person or by
proxy at the Extraordinary General Meeting. On a show of hands, each shareholder
will have one vote, and on a poll, each shareholder will have one vote for each
ordinary share held by him.



QUORUM REQUIREMENTS (PAGE 31)



    Saville has been advised by McCann FitzGerald, its Irish counsel, that,
unless the High Court decides that the circumstances justify a different quorum,
two holders of record of ordinary shares or (as the case may be) deferred shares
(other than John J. Boyle III) entitled to vote at the relevant Meeting, each
appearing in person or by proxy, will constitute a quorum for the transaction of
business at the Scheme Ordinary Meeting or (as the case may be) the Scheme
Deferred Meeting.


    Three holders of record of ordinary shares, each appearing in person or
represented by proxy, will constitute a quorum for the transaction of business
at the Extraordinary General Meeting.


VOTES REQUIRED (PAGE 32)


    SCHEME ORDINARY MEETING.  In order to consummate the Acquisition, the Scheme
must be approved at the Scheme Ordinary Meeting by (i) a majority in number of
those holders of ordinary shares present and voting in person or by proxy and
(ii) 75% in value of those holders of ordinary shares present and voting in
person or by proxy. The custodian for the Depositary is the shareholder of
record in respect of those ordinary shares represented by ADSs.


    As of July 20, 1999 executive officers, directors and their affiliates
(other than the Excluded Officers) beneficially owned an aggregate of 1,893,348
ordinary shares, or approximately 4.8% of the outstanding ordinary shares.



    SCHEME DEFERRED MEETING.  In order to consummate the Acquisition, the Scheme
must be approved at the Scheme Deferred Meeting by (i) a majority in number of
those holders of deferred shares present and voting in person or by proxy and
(ii) 75% in value of those holders of deferred shares present and voting in
person or by proxy (other than John J. Boyle III, who will not be entitled to
vote at the Scheme Deferred Meeting but has agreed to be bound by the Scheme in
respect of those shares).



    As of July 20, 1999, executive officers, directors and their affiliates
(other than Mr. Boyle) beneficially owned an aggregate of 14,813 deferred
shares, or approximately 49.4% of the deferred shares.



    EXTRAORDINARY GENERAL MEETING.  In order to consummate the Acquisition, the
resolution to be proposed at the Extraordinary General Meeting must be approved
by not less than 75% of the votes cast at the Extraordinary General Meeting by
the holders of ordinary shares. The custodian for the Depositary is the
shareholder of record in respect of those ordinary shares represented by ADSs.



EFFECT OF ABSTENTIONS AND BROKER NON-VOTES (PAGE 32)



    Holders of shares that abstain from voting such shares and holders of ADRs
that instruct the Depositary not to vote the shares represented by ADSs which
their ADRs evidence as to a particular matter will not have such shares counted
as votes in favor of such matter, and such shares also will not be counted as
shares voted on such matter and may not count towards a quorum on such matter.
Accordingly, such abstentions will have no effect on the voting on the matters
presented for approval by the shareholders at any of the Meetings. Under the
terms of Saville's agreement with the Depositary, Saville


                                       6
<PAGE>

shall be deemed to have received a proxy to vote those ordinary shares
represented by ADSs where the holders do not instruct the Depositary how to
vote, including those ordinary shares represented by ADSs held in "street name"
by a broker or nominee who indicates on a form of instructions that he does not
have discretionary authority to instruct the Depositary how to vote as to a
particular matter. Saville intends to vote all such ordinary shares represented
by ADSs FOR the proposals presented at the Meetings. Accordingly, broker
non-votes will have the same effect as a vote for the matters presented for
approval at the Meetings.



REQUIREMENTS AS TO PROXIES (PAGE 33)



    To be valid, a proxy form for any of the Meetings must be deposited not less
than 48 hours prior to the time appointed for the holding of that Meeting at the
offices of Saville's Registrar, Computer Share Services (Ireland) Limited, Heron
House, Corrig Road, Sandyford Industrial Estate, Dublin 18, or the registered
office of Saville, IDA Business Park, Dangan, Galway, Ireland, or, in the case
of the Scheme Ordinary Meeting or the Scheme Deferred Meeting, delivered to the
Chairman of the relevant Meeting at such Meeting.


    Any proxy may be revoked at any time by a shareholder before its being voted
by:

    - voting in person at the relevant Meeting (although mere personal
      attendance at the relevant Meeting will not constitute a revocation of a
      proxy);


    - delivery of a subsequently dated proxy, provided that such subsequently
      dated proxy must be received at either of the above offices not less than
      48 hours prior to the time appointed for holding of the relevant Meeting,
      or, in the case of the Scheme Ordinary Meeting or the Scheme Deferred
      Meeting, delivered to the Chairman of the relevant Meeting at such
      Meeting; or


    - delivery of written revocation of such proxy, provided that such
      revocation must be received at either of the above offices not less than
      one hour prior to the time appointed for the holding of the relevant
      Meeting.


THE ACQUISITION AGREEMENT AND THE SCHEME (PAGE 51)


    The Acquisition Agreement is attached as Annex A to this Proxy Statement and
the Scheme is attached as Annex B to this Proxy Statement. We encourage you to
read the Acquisition Agreement and the Scheme as they are the legal documents
that govern the Acquisition.


INTERESTS OF CERTAIN PERSONS IN THE ACQUISITION (PAGE 43)



    A number of executive officers and directors of Saville have interests in
the Acquisition that are or may be different from or in addition to your
interests. Seven executive officers of Saville have executed employment
agreements with ADC which provide for certain benefits and the issuance of
shares of ADC common stock or the grant of additional options to purchase ADC
common stock. Certain executive officers and directors will also receive ADC
options in exchange for Saville options. These options will become fully vested
upon consummation of the Acquisition. In addition, ADC has agreed to make
severance payments to 21 executives of Saville if, within 12 months following
the Acquisition, the executive's employment with ADC is terminated by ADC
"without cause" or by the executive for "good reason" (as each such phrase is
defined in the severance arrangements).



CONDITIONS TO THE ACQUISITION (PAGE 54)


    The consummation of the Acquisition depends upon meeting a number of
conditions set forth in the Acquisition Agreement, including, among others, the
following:

    - obtaining the requisite approvals by our shareholders;

                                       7
<PAGE>
    - absence of governmental prohibitions to consummation of the Acquisition or
      governmental actions seeking any such prohibition;

    - obtaining required judicial, governmental and other regulatory
      authorizations, consents, orders, approvals of or declarations or filings
      with, or expiration or waiver of waiting periods imposed by any
      governmental entity or any applicable jurisdiction or exemptions,
      including the sanctioning of the Scheme and the confirmation of the
      reduction of Saville's capital by the High Court;

    - receipt by Saville and ADC of certain letters from their respective
      auditors with respect to the accounting treatment of the Acquisition as a
      "pooling of interests";

    - receipt of an opinion of legal counsel as to the U.S. federal income tax
      treatment of the Acquisition; and

    - absence of a material adverse change in Saville's business.

    Certain of the conditions to the consummation of the Acquisition may be
waived by the party entitled to the benefit of the condition.


TERMINATION OF THE ACQUISITION AGREEMENT AND ABANDONMENT OF THE SCHEME (PAGE 56)


    Saville and ADC can jointly agree to terminate the Acquisition Agreement and
abandon the Scheme at any time. Either party may also terminate the Acquisition
Agreement and abandon the Scheme under certain circumstances, including, among
others:

    - the Acquisition is not completed by December 31, 1999;

    - any governmental entity has taken action, which is final and binding, to
      prohibit the Acquisition;

    - Saville does not obtain the requisite shareholder approvals or sanction of
      the High Court;


    - judgments, orders, decrees, statutes, laws, ordinances, rules or
      regulations are entered, enacted, promulgated, enforced or issued by any
      court or government entity or other legal restraint or prohibition having
      certain material effects on Saville or ADC are in effect and are final and
      nonappealable; or


    - the other party materially breaches any representation, warranty, covenant
      or agreement in the Acquisition Agreement.

    In addition, under certain circumstances, either party may terminate the
Acquisition Agreement and abandon the Scheme if Saville enters into an agreement
to effect a Superior Proposal (as defined in the Acquisition Agreement) proposed
by a third party. ADC may also terminate the Acquisition Agreement if Saville
withdraws or modifies, in a manner adverse to ADC, its approval of the
Acquisition or if Saville approves an Acquisition Proposal (as defined in the
Acquisition Agreement), including a Superior Proposal.


OPINION OF SAVILLE'S FINANCIAL ADVISOR (PAGE 38)



    Morgan Stanley & Co. Incorporated ("Morgan Stanley"), acting as Saville's
financial advisor in connection with the Scheme, rendered its oral opinion
(which was subsequently confirmed by delivery of a written opinion dated June
18, 1999) to Saville's Board of Directors to the effect that, as of the date of
such opinion and based upon and subject to various conditions set forth in its
opinion, the Ordinary Share Allotment Ratio as set forth in the Scheme is fair,
from a financial point of view, to holders of Saville's ordinary shares. Morgan
Stanley's opinion is summarized on pages 38 to 42 and the full text of the
opinion is attached as Annex C to this Proxy Statement. Morgan Stanley's opinion
is not a recommendation as to how holders of ordinary shares or deferred shares
should vote at the Meetings. Saville encourages you to read Morgan Stanley's
opinion in its entirety.

THE HIGH COURT SANCTION HEARING (PAGE 43)



    The hearing by the High Court of Saville's application for the sanction of
the Scheme and the confirmation of the proposed reduction of capital will take
place on a day which will be appointed by the High Court following a separate
application for that purpose. At the same time as the High Court appoints the
day for hearing, it will direct how the date of the hearing should be
advertised. Saville will propose that such advertising should be placed in the
legal notices sections (or similar available alternative section) in the Wall
Street Journal and The Irish Times newspapers. All holders of ordinary shares
and of deferred shares are entitled to attend and be heard at the hearing in
person or through a professional lawyer. Submissions and arguments to the High
Court are generally made orally, but any facts other than those expressed in
Saville's own documents which a person wishes to put forward must be put forward
as evidence in the form of sworn written statements (an "affidavit" being the
standard form for this in Irish practice). Any person proposing to make
submissions or put forward evidence to the High Court at the hearing will be
requested to advise Saville's Irish lawyers in advance and they in turn will
advise the High Court. Individuals may make these submissions personally or by a
professional lawyer entitled to appear in High Court in Ireland (a "solicitor"
or "barrister" in Irish practice).



    The hearing will take place on the advertised date or on adjourned dates
then fixed by the High Court. The High Court will consider the submissions and
evidence presented to it so as to establish whether the requirements of Irish
law and Saville's corporate constitution (its "memorandum and articles of
association") so far as these are applicable have been complied with, whether
the necessary majorities of Saville's shareholders of record have voted in favor
of approving the Scheme and the resoluton for the reduction of Saville's
capital, and whether the Scheme and reduction of capital are fair and reasonable
in all circumstances. The High Court may announce its decision immediately after
the hearing or may defer this until a date to be announced later.



REGULATORY FILINGS AND APPROVALS (PAGE 46)


    In order to consummate the Acquisition, both ADC and Saville must make
certain filings and receive authorizations from various governmental agencies.
These include, but are not limited to:

    - the sanctioning of the Scheme by the High Court after a hearing on the
      fairness of the Acquisition;

    - the expiration or termination of the applicable waiting period, or any
      extensions thereof, pursuant to the U.S. Hart-Scott-Rodino Antitrust
      Improvements Act of 1976 (the "HSR Act");

    - written clearance from the Irish Minister for Enterprise, Trade and
      Employment (or elapsing of the relevant waiting period) under the Mergers,
      Takeovers and Monopolies (Control) Act, 1978, as amended (the "Irish
      Control Act"); and

    - similar orders or expiration of the applicable waiting periods from the
      appropriate authorities in Canada and Australia.

    It is possible that some of these governmental authorities may impose
conditions for granting approval. We cannot predict whether we will obtain all
of the required regulatory approvals within the time frame contemplated by the
Acquisition Agreement or without burdensome conditions.


EFFECTIVE TIME OF THE ACQUISITION (PAGE 43)



    The Acquisition will be consummated upon delivery to the Registrar of
Companies in Dublin, Ireland, of a copy of the final order of the High Court
sanctioning the Scheme and confirming the reduction of Saville's capital, and
the registration by the Registrar of the order confirming the reduction of
Saville's capital.

U.S. FEDERAL INCOME TAX CONSEQUENCES (PAGE 48)


    Saville intends that the Acquisition will be treated as a tax-free
reorganization. If it qualifies as a reorganization U.S. Holders (as defined
herein) will not recognize a gain or loss as a result of the consummation of the
Acquisition and the receipt of shares of ADC common stock in exchange for your
ordinary shares or deferred shares.


IRISH TAX CONSEQUENCES (PAGE 50)



    The receipt of ADC common stock in consideration for the cancellation of
ordinary shares or deferred shares will not give rise to Irish capital gains
tax.



    The assumption of Saville options by ADC and their conversion into ADC
options is not a taxable event under Irish law.



ACCOUNTING TREATMENT (PAGE 47)



    ADC and Saville intend for the Acquisition to be treated as a pooling of
interests for accounting and financial reporting purposes. Under this method of
accounting, the recorded assets and liabilities of Saville will be carried
forward to ADC at their recorded amounts, income of ADC will include income or
loss of Saville for the entire fiscal year in which the combination occurs and
the reported income or loss of the separate companies for prior periods will be
combined and restated as income or loss of ADC. Saville received a letter from
PricewaterhouseCoopers LLP, its independent accountants, dated June 18, 1999,
stating that Saville will qualify as a party to a pooling of interests
transaction. ADC received a letter from Arthur Andersen LLP, its independent
accountants, dated June 18, 1999, stating that ADC will qualify as a party to a
pooling of interests transaction. It is a condition to consummation of the
Acquisition that neither of these letters be withdrawn or modified in any
respect as of the Effective Date (as defined in the Scheme) and that ADC shall
have received a letter from Arthur Andersen LLP, dated as of the Effective Date,
stating that the Acquisition will qualify as a pooling of interests transaction
under Accounting Principles Board Opinion No. 16 and applicable regulations of
the U.S. Securities and Exchange Commission (the "Commission").



TERMINATION FEE (PAGE 56)


    Pursuant to the Acquisition Agreement, Saville has agreed to pay ADC's
actual expenses up to $1,500,000 if the Acquisition Agreement is terminated in
certain circumstances, including:

    - as a result of Saville's shareholders' failure to approve the Acquisition
      and if, after the date of the Acquisition Agreement and prior to its
      termination date, an Acquisition Proposal (as defined in the Acquisition
      Agreement) occurs;

    - if Saville breaches a representation or warranty of the Acquisition
      Agreement which breach has or is reasonably likely to have a material
      adverse effect on Saville or Saville fails to perform its covenants or
      agreements, and fails to cure such breach within 30 days following receipt
      of notice thereof from ADC;

    - Saville's Board of Directors withdraws or modifies in any manner adverse
      to ADC its recommendation of the Scheme; or

    - Saville enters into an agreement to effect a Superior Proposal (as defined
      in the Acquisition Agreement) prior to termination of the Acquisition
      Agreement.

    In addition, Saville has agreed to pay ADC a fee of $21,000,000 if the
Acquisition Agreement is terminated in certain other circumstances, including:


    - if the Acquisition Agreement is terminated due to the failure to obtain
      shareholder approval or if Saville breaches a representation or warranty
      that has or is likely to have a material adverse effect


                                       10
<PAGE>

      on Saville or fails to perform its covenants or agreements, and fails to
      cure such breach within 30 days after receiving notice of such breach, and
      (1) concurrently or within nine months after such termination, Saville
      enters into an agreement, arrangement or binding understanding with
      respect to an Acquisition Proposal or a tender offer or exchange offer or
      similar transaction directly with Saville's shareholders for the
      acquisition of a majority of the outstanding ordinary shares which has
      been unilaterally commenced by a third party that made an Acquisition
      Proposal at or prior to the time of such termination shall have become
      unconditional or irrevocable, or (2) within six months after such a
      termination, if some other third party made an Acquisition Proposal at or
      prior to the time of such termination, and either Saville shall enter into
      a Third Party Deal (as defined in the Acquisition Agreement) with any
      other third party or a Hostile Tender (as defined in the Acquisition
      Agreement) commenced by any other third party shall have become
      unconditional or irrevocable;


    - the breach by Saville of its non-solicitation covenant;

    - Saville's entering into an agreement or understanding to effect a Superior
      Proposal (as defined in the Acquisition Agreement); or

    - the withdrawal by the Board of Directors of Saville of its approval or
      recommendation of the Acquisition Agreement or the Acquisition or the
      approval or recommendation by Saville's Board of Directors of an
      Acquisition Proposal. See "The Acquisition Agreement and the
      Scheme--Termination; Termination Fees and Expenses."


SHARE OPTION (PAGE 58)


    Saville has granted ADC an option to purchase up to 7,799,805 ordinary
shares of Saville (which represented 19.9% of the issued and outstanding
ordinary shares as of the date of the Acquisition Agreement) exercisable if the
Acquisition Agreement is terminated and the Scheme is abandoned under certain
circumstances. The exercise price of this option is $17.50 per share, payable in
cash. The option agreement contains other features which, among other things,
permit ADC to require Saville to purchase the option from ADC for cash and limit
the profit which ADC can realize in connection with the option and Termination
Fee combined to $21,000,000.


NO RIGHT TO DISSENT (PAGE 32 AND 48)


    Under Irish law, after the Effective Time (as defined in the Scheme) you
will not have a right to dissent and obtain payment of the "fair value" for, or
otherwise seek approval of the value of, your ordinary shares, deferred shares
or Saville options with respect to the Acquisition.


SURRENDER OF SHARE CERTIFICATES AND ADRS (PAGE 48)



    Following the Effective Time, ADC will cause a letter of transmittal to be
mailed to all holders of ordinary shares (including those represented by ADSs
evidenced by ADRs) and deferred shares containing instructions for surrendering
their certificates representing ordinary shares and deferred shares and ADRs.
CERTIFICATES AND ADRS SHOULD NOT BE SURRENDERED UNTIL THE LETTER OF TRANSMITTAL
IS RECEIVED, FULLY COMPLETED AND RETURNED BY SUCH HOLDER AS INSTRUCTED IN THE
LETTER OF TRANSMITTAL.



CERTAIN EFFECTS OF THE ACQUISITION (PAGES 63 AND 64)



    Upon consummation of the Acquisition, holders of Saville's ordinary shares
and deferred shares will become shareholders of ADC. The internal affairs of ADC
are governed by the Minnesota Business Corporation Act and ADC's Restated
Articles of Incorporation and Bylaws. The Acquisition will result in certain
differences in the rights of holders of Saville ordinary shares and deferred
shares. See "Description of ADC Capital Stock" and "Comparison of Shareholder
Rights."

                  UNAUDITED PRO FORMA COMBINED FINANCIAL DATA


    The following unaudited pro forma financial statements give effect to the
Acquisition to be accounted for as a pooling of interests. The unaudited pro
forma condensed balance sheet presents the combined financial position of ADC
and Saville as of April 30, 1999 assuming that the proposed Acquisition had
occurred as of April 30, 1999. Such pro forma information is based upon the
historical balance sheet data of ADC as of April 30, 1999 and Saville as of
March 31, 1999. The unaudited pro forma condensed statements of income give
effect to the proposed Acquisition by combining the results of operations of ADC
for the three years ended October 31, 1998 and for the six months ended April
30, 1999 with the results of operations of Saville for the three years ended
September 30, 1998 and the six months ended March 31, 1999, respectively, on a
pooling of interests basis. These unaudited pro forma financial statements
should be read in conjunction with the historical financial statements of ADC
and Saville and notes thereto included elsewhere in this Proxy Statement.

                                 THE COMPANIES

SAVILLE

    Saville provides innovative convergent customer care and billing solutions
to service providers in the global telecommunications and energy industries.
Saville offers products and services designed to enable telecommunications and
energy service providers to bring new service offerings to market quickly, and
to bill accurately and reliably for multiple services on one convergent invoice.
In order to meet the current and evolving billing requirements of its customers,
Saville continuously refines its sophisticated convergent billing platform
(CBP-Registered Trademark-) software products for both the
UNIX/Oracle-Registered Trademark- and DB2/400 platforms. The customer can either
license CBP from Saville or CBP can be provided by a Company-operated service
bureau. Saville has also introduced facilities management services, which allow
customers to license CBP from Saville and have Saville manage the operation of
the software on customer owned hardware. Additionally, Saville has developed
relationships with authorized integrators to assist it in providing
implementation services to purchasers of CBP products. Saville also offers its
interconnect billing platform (IBP-TM-) software product which allows
telecommunications companies to bill for carrier-to-carrier transactions and its
SavilleCare-TM- product and SavilleExpress-TM- GSM products. SavilleCare allows
telecommunications service providers to integrate the SavilleCare call center
desktop with the providers' billing and other business support systems.
SavilleExpress GSM is a pre-configured module that, through the SavilleExpress
modular billing platform, supports the billing of services using the Global
Systems for Mobile Communications (GSM) standard for wireless
telecommunications. Each of these three products was developed from technologies
purchased in 1998.

    In addition to its product offerings, Saville provides its customers with a
full range of professional services, including assisting a customer in analyzing
its requirements and then designing, developing and implementing a customer care
and billing solution. Saville assists its customers on an ongoing basis by
addressing their changing business needs through future enhancements and
developments to their customer care and billing solutions.

    For a more detailed description of the business of Saville, see the
descriptions thereof set forth in Saville's Annual Report on Form 10-K for the
year ended December 31, 1998 and Quarterly Report on Form 10-Q for the quarter
ended March 31, 1999. See "Where You Can Find More Information."

ADC

    ADC offers a broad range of products and services that enable its customers
to construct and upgrade their communications networks to support increasing
user demand for voice, Internet/data and video services. Telephone companies,
cable television operators, wireless service providers and other public
communications network service providers are building the infrastructure
required to offer high-speed Internet access, data, video, telephony and other
interactive multimedia services to residential and business customers. Broader
network bandwidths are required for these services, and ADC's development
efforts and product offerings are focused on "unlocking the capacity of the
local loop" by eliminating bottlenecks and increasing the speed and efficiency
of the network. The local loop is the portion of the public communications
network from the local service providers' offices through the network equipment
that connects to the subscribers' equipment at their residence or business.

    ADC offers hardware, software, services and integrated solutions within the
following three product groups: Broadband Connectivity, Broadband Transport and
Access, and Integrated Solutions. Broadband Connectivity products are designed
for use in twisted-pair, coaxial, fiber optic or wireless transmission networks
and are sold to both public and private global service providers. ADC's
Broadband Connectivity products provide the physical contact points for
connecting different communications system components and gaining access to
communications system circuits for the purpose of installing, testing,
monitoring, accessing, managing, reconfiguring, splitting and multiplexing such
circuits within global public and private networks. Broadband Transport and
Access products enable incumbent local exchange carrier (ILEC),

                                       21
<PAGE>

competitive local exchange carriers (CLEC), inter-exchange carriers (IXC),
community antenna television (CATV) and wireless service providers to transport
and/or provide access to the services they sell to their business and
residential customers. These products are best categorized as "Service Delivery
Infrastructure," and the services being delivered include voice, data (including
Internet services), and video. Broadband Transport and Access transport products
operate in the Interoffice and/or Loop Transport portion of the service
provider's network and include Soneplex-Registered Trademark-, Cellworx-TM-,
Homeworx-TM-, DV6000-TM- and BroadAccess-TM-. Integrated Solutions products and
services consist of project management, technical consulting design,
implementation, reliability, performance and training services, and software
systems, which support multidivision and multi-vendor solutions. ADC's customers
include: public network providers, which consist of the U.S. Regional Bell
Operating Companies (RBOCs), post telephone and telegraph companies (PTTs),
other telephone companies, long distance carriers, wireless service providers,
cable TV operators, Internet service providers and other international and
domestic public network providers; private and governmental network providers
(such as various large business customers and governmental agencies); and
communications original equipment manufacturers (OEMs).


    For a more detailed description of the business of ADC, see the descriptions
thereof set forth in ADC's Annual Report on Form 10-K for the year ended October
31, 1998 and Quarterly Reports on Form 10-Q for the quarters ended January 31,
1999 and April 30, 1999, respectively. See "Where You Can Find More

                                  RISK FACTORS

    The following risk factors relating to the Acquisition and the ownership of
ADC common stock should be considered carefully by shareholders and in addition
to the other information contained in or to which you are referred in this Proxy
Statement.

RISKS RELATING TO THE ACQUISITION

    FLUCTUATION IN VALUE OF ADC COMMON STOCK

    The market price of ADC common stock is inherently subject to fluctuation.
The Ordinary Share Allotment Ratio and the Deferred Share Allotment Ratio were
each fixed as of the close of business on June 18, 1999, the last trading day
prior to the date that the Acquisition Agreement was executed by Saville and
ADC. Therefore, the value of the ADC common stock to be issued in connection
with the Acquisition may increase or decrease prior to or after the effective
time of the Acquisition.

    Fluctuations in the market price of ADC's common stock may be the result of
market assessments of the prospects of ADC or its competitors and of the
likelihood and timing of closing the Acquisition. These assessments may be
unsubstantiated. In addition, general market conditions and other factors, many
of which are beyond the control of ADC or Saville, may also affect the market
price of ADC's common stock.

    Based on the trading history of its stock, ADC believes factors such as
announcements of new products by ADC or its competitors, quarterly fluctuations
in ADC's financial results or the financial results of its competitors, customer
contract awards, developments in telecommunications regulation, general
conditions in the telecommunications equipment industry, general economic
conditions and general conditions in financial markets have caused and are
likely to continue to cause the market price of ADC's common stock to fluctuate
substantially. In addition, telecommunications equipment company stocks have
experienced significant price and volume fluctuations that often have been
unrelated to the operating performance of such companies. This market volatility
may adversely affect the market price of ADC's common stock.

    CONDITIONS TO CONSUMMATION OF THE ACQUISITION

    The consummation of the Acquisition is subject to the approval of the
shareholders of Saville, as well as other conditions, including sanctioning of
the Scheme by the High Court and U.S., Irish and certain other regulatory
approvals and consents. Saville and ADC cannot predict whether such approvals
will be obtained and there can be no assurance that the Acquisition will be
consummated. See "The Acquisition Agreement and the Scheme--Conditions." There
can be no assurance that the High Court will render the Final Court Order (as
defined in the Acquisition Agreement) even if the Scheme is approved by the
requisite votes at the Meetings. The High Court has broad discretion under
Section 201 of the Companies Act in sanctioning the Scheme and objections to the
approval of the Scheme may be submitted to the High Court by shareholders and
other parties. The High Court is authorized, at its discretion, to issue an
order rejecting the Scheme or approving the Scheme subject to modifications.
Among other factors, the High Court considers the fairness of the Scheme and any
objections filed by objecting parties.

    UNCERTAINTY AS TO APPROVAL OF ANTITRUST AUTHORITIES


    A condition to the consummation of the Acquisition is that Saville and ADC
provide certain required information to each of the Irish Minister for
Enterprise, Trade and Employment, the United States Federal Trade Commission and
Department of Justice, the Australian Treasurer and the Commissioner of
Competition (Canada). Applicable waiting periods must then expire or the parties
must then receive approvals or consents from each of the regulatory authorities
described in the foregoing sentence. At any time before of after consummation of
the Acquisition, regulatory authorities could take action under antitrust laws
as each deems necessary or desirable in the public interest, including seeking
to enjoin the


                                       23
<PAGE>

consummation of the Acquisition or seeking divestiture of assets of Saville or
ADC. Private parties may also seek to take legal action under the antitrust laws
under certain circumstances. There can be no assurance that a challenge to the
consummation of the Acquisition on antitrust grounds will not be made or that,
if such a challenge were made, Saville or ADC would prevail or would not be
required to accept certain conditions, including the divestiture of assets
and/or commitments as to future business practices and other matters in order to
consummate the Acquisition.


RISKS RELATING TO ADC

    RAPID TECHNOLOGICAL CHANGE AND IMPORTANCE OF NEW PRODUCTS

    The telecommunications equipment industry is characterized by rapid
technological change, evolving industry standards, changing market conditions
and frequent new product introductions and enhancements. The introduction of
products using new technologies or the adoption of new industry standards can
make existing products or products under development obsolete or unmarketable.
In order to grow and remain competitive, ADC will need to anticipate changes in
technology and industry standards and successfully develop and introduce new
products on a timely basis. New product development often requires long-term
forecasting of market trends, development and implementation of new technologies
and processes and a substantial capital commitment. ADC has recently invested
and continues to invest substantial resources for the development of new
products. Development and customer acceptance of new products is inherently
uncertain. As a result, ADC cannot predict whether it will successfully develop
new products on a timely basis or whether the products will be commercially
successful. If ADC fails to anticipate or respond on a cost-effective and timely
basis to technological developments, changes in industry standards or customer
requirements, or if ADC has any significant delays in product development or
introduction, ADC's business, operating results and financial condition could be
materially, adversely affected.

    UNCERTAIN MARKET FOR BROADBAND COMMUNICATIONS PRODUCTS AND SERVICES

    In the past, ADC's principal product offerings have been copper-based and
fiber-optic-based products designed to connect and transmit information on
traditional telephony networks. With the growth of multimedia applications and
the development of enhanced voice, video and Internet/data services, ADC's
recent product offerings and research and development efforts have been and are
focused on new technologies and hardware, software and service offerings for
broadband telecommunications applications. The market for broadband
telecommunications hardware, software and services is rapidly changing. ADC's
future growth is dependent in part on its ability to successfully develop and
commercially introduce new products for this market. ADC's future will also
depend on the growth of this market. The growth in the market for broadband
telecommunications products is dependent on a number of factors. These factors
include the amount of capital expenditures by public network providers,
regulatory and legal developments, changes to capital expenditure rates by the
other network providers (which could result from consolidation of customers in
the market as well as the addition of new customers to the market) and end-user
demand for integrated voice, video, Internet/data and other network services.
ADC cannot predict whether the market for broadband telecommunications products
will develop rapidly. ADC also cannot predict technological trends or new
products in this market. In addition, to the extent this market develops, ADC
cannot predict whether its products will meet with market acceptance or be
profitable. ADC may not be able to compete successfully, and competitive
pressures may materially and adversely affect its business, operating results
and financial condition.

    COMPETITION

    Competition in the telecommunications equipment industry is intense. ADC
believes that competition may increase substantially with the increased use of
broadband networks and recent regulatory changes. Many of ADC's foreign and
domestic competitors have more extensive engineering, manufacturing,

                                       24
<PAGE>
marketing, financial and personnel resources than ADC has. ADC believes its
success in competing with other manufacturers of telecommunications products
will depend primarily on its engineering, manufacturing and marketing skills,
the price, quality and reliability of its products, and its delivery and service
capabilities. ADC anticipates increasing pricing pressures from current and
future competitors. In addition, ADC believes that technological change, the
increasing addition of Internet/data, video and other services to networks,
continuing regulatory change and industry consolidation or new entrants will
continue to cause rapid evolution in the competitive environment. The full scope
and nature of these changes is difficult to predict at this time. Increased
competition could result in price reductions, reduced margins and loss of market
share by ADC. ADC cannot predict whether it will be able to compete successfully
with its existing products or with new competitors. Competitive pressures faced
by ADC could materially and adversely affect its business, operating results and
financial condition.

    FLUCTUATIONS IN OPERATING RESULTS

    ADC's operating results may vary significantly from quarter to quarter due
to several factors, including, without limitation, the volume and timing of
orders from, and shipments to, major customers, the timing of and the ability to
obtain new customer contracts, the timing of new product announcements and the
availability of product by ADC or its competitors, overall level of capital
expenditures by public network providers, market acceptance of new and enhanced
versions of ADC's products, variations in the mix of products ADC sells or its
sales channels, and the availability and cost of key components. Many of these
factors are affected by the changing competitive environment in which ADC's
customers operate and may be affected by consolidation among telecommunications
service providers. In addition, ADC is growing through acquisition and
expansion, and its recent results of operations may not be indicative of results
to be achieved in future periods. ADC's expense levels are based in part on
expectations of future revenues. If revenue levels in a particular period do not
meet expectations, operating results will be adversely affected. In addition,
ADC's results of operations are subject to seasonal factors. ADC historically
has experienced a stronger demand for its products in the fourth fiscal quarter,
primarily as a result of ADC year-end incentives and customer budget cycles, and
has experienced a weaker demand for its products in the first fiscal quarter,
primarily as a result of the number of holidays in late November, December and
early January and a general industry slowdown during that period. ADC cannot
predict if historical seasonal trends will continue in the future. In addition,
it is possible that some of ADC's customers may reduce their level of
expenditures for ADC's products, particularly software products, in the last
half of calendar year 1999 as a precautionary measure relating to the year 2000
problem with computer systems in general.

    CHANGING REGULATORY ENVIRONMENT

    The telecommunications industry is subject to regulation in the United
States and other countries. ADC's business is dependent upon the continued
growth of the telecommunications industry in the United States and
internationally. Federal and state regulatory agencies regulate most of ADC's
domestic customers. In early 1996, the U.S. Telecommunications Act of 1996 (the
"Telecommunications Act") was enacted. The Telecommunications Act lifted certain
restrictions on the ability of companies, including RBOCs and other customers of
ADC, to compete with one another. The Telecommunications Act also made other
significant changes in the regulation of the telecommunications industry. While
ADC believes that the changes could increase ADC's opportunities to provide
solutions for its customers' voice, data and video needs, this result is
dependent on the reaction of ADC's existing and prospective customers to these
new regulatory trends. To date, increased competition among telecommunications
service providers as contemplated by the Telecommunications Act has not been
fully realized, and ADC cannot predict the timing and intensity of new
competition. The effect on the market for ADC's products is difficult to
predict, and ADC does not know whether competition in its product market will
not intensify as a result of the changes in regulation. Changes in current or
future laws or regulations, in the United States or elsewhere could materially
and adversely affect ADC's business.

                                       25

    INTERNATIONAL OPERATIONS

    Export sales accounted for 20% of ADC's net sales in fiscal 1998, 21% of
ADC's net sales in each of fiscal 1997 and 1996, and 21.5% of ADC's net sales in
the six months ended April 30, 1999. ADC expects export sales to increase as a
percentage of net sales in the future. In addition to sales and distribution
activities in numerous countries, ADC owns or subcontracts operations located in
Australia, China, Finland, Israel, Mexico, and the United Kingdom. Due to its
export sales and its international manufacturing operations, ADC is subject to
the risk of conducting business internationally. These risks include unexpected
changes in or impositions of legislative or regulatory requirements,
fluctuations in the U.S. dollar, and tariffs and other barriers and
restrictions. Other potential risks include longer payment cycles, greater
difficulty in accounts receivable collection, potentially adverse taxes, and the
burdens of complying with a variety of foreign laws and telecommunications
standards. ADC also is subject to general geopolitical risks, such as political
and economic instability and changes in diplomatic and trade relationships. ADC
maintains business operations and has sales in many international markets,
including Asia and Latin America. Economic conditions in these markets represent
significant risks to ADC. ADC cannot predict whether its sales and business
operations in these markets will be adversely affected by these conditions.
Instability in foreign markets, particularly in Asia and Latin America, could
negatively impact ADC's results of operations. Potential turmoil in the Middle
East could also negatively impact ADC's results of operations and asset
valuation for its Israeli subsidiary, Teledata Communications Ltd. In addition
to the effect of international economic instability on foreign sales, domestic
sales to U.S. customers having significant foreign operations could be adversely
affected by these economic conditions. ADC cannot predict whether or not these
factors will not materially and adversely affect ADC's operations in the future.
In addition, the laws of certain foreign countries may not protect ADC's
proprietary technology to the same extent as to the laws of the United States.

    DEPENDENCE ON PROPRIETARY TECHNOLOGY

    ADC's future success depends in part upon its proprietary technology.
Although ADC attempts to protect its proprietary technology through patents,
copyrights and trade secrets, its future success will depend upon product
development, technological expertise and distribution channels. ADC cannot
predict whether it can protect its technology, or whether competitors can
develop similar technology independently. ADC has received and may continue to
receive from third parties, including some of its competitors, notices claiming
that it is infringing third-party patents or other proprietary rights. ADC
cannot predict that it will prevail in any litigation over third-party claims,
or that it would be able to license any valid and infringed patents on
commercially reasonable terms. Furthermore, litigation, regardless of its
outcome, could result in substantial cost to and diversion of effort by ADC. Any
litigation or successful infringement claims by third parties could materially
and adversely affect ADC's business, operating results and financial condition.

    YEAR 2000 MATTERS

    Many currently installed computer systems and software are coded to accept
only two digit entries in date code fields. These date code fields will need to
accept four-digit entries to distinguish 21st century dates from 20th century
dates. This problem could result in system failures or miscalculations causing
disruptions of business operations (including a temporary inability to process
transactions, send invoices or engage in other business activities). As a
result, many companies' computer systems and software will need to be upgraded
or replaced in order to comply with Year 2000 requirements. The potential global
impact of the Year 2000 problem is not known, and, if not corrected in a timely
manner, could affect ADC and the U.S. and world economy generally. ADC's product
development processes currently contain steps to include Year 2000 readiness
verification for all current and future products. ADC believes that most of
ADC's products are currently Year 2000 ready. A few of ADC's products, which
contain minor Year 2000 issues, will be phased out prior to the Year 2000. A few
other ADC products contain minor performance

                                       26
<PAGE>
issues that do not affect performance or service. Although there can be no
assurance, ADC believes that readiness for any of its other products that are
not Year 2000 ready will be achieved prior to January 1, 2000.

    On June 18, 1999, the last trading day before public announcement of the
execution of the Acquisition Agreement, the closing price of Saville's ADRs was
$15.625 per share and the closing price of ADC's common stock was $50.125 per
share, in each case, as quoted on the Nasdaq National Market. On July 20, 1999,
the most recent practicable date prior to printing this Proxy Statement, the
closing price of Saville's ADRs was $13.1875 per share and the closing price of
ADC's common stock was $41.8125 per share, in each case, as quoted on the Nasdaq
National Market.



    Because the market price of ADC's common stock is subject to fluctuation,
the market value of ADC's common stock that holders of Saville's ordinary shares
(including holders of Saville's ADSs) and deferred shares will receive in the
Acquisition may increase or decrease prior to the Acquisition.


    Prior to its initial public offering, Saville paid a cash dividend of $3.0
million on its ordinary shares on September 25, 1995. Saville paid this dividend
because of certain tax liabilities incurred by its majority shareholders as a
result of their ownership interests in Saville and Saville's classification at
the time as a "Controlled Foreign Corporation." Saville has never declared or
paid any other cash dividends on its

                                       28
<PAGE>
ordinary shares or deferred shares, and pursuant to the Acquisition Agreement,
has agreed not to declare or pay any dividends prior to consummation of the
Acquisition.

    ADC has never declared or paid any cash dividends on ADC's common stock, and
pursuant to the Acquisition Agreement, has agreed not to declare or pay any
dividends in excess of $1.00 per share prior to consummation of the Acquisition.

    SHAREHOLDERS ARE URGED TO OBTAIN CURRENT MARKET QUOTATIONS FOR SAVILLE'S
ADRS AND ADC'S COMMON STOCK.

                                  THE MEETINGS

GENERAL


    The Acquisition is to be effected principally by means of a scheme of
arrangement under Section 201 of the Companies Act, 1963. The Scheme will
require the approval of the holders of ordinary shares at the Scheme Ordinary
Meeting and the approval of the holders of the deferred shares (other than John
J. Boyle III) at the Scheme Deferred Meeting. Both of those Meetings are being
held at the direction of the High Court. The Acquisition also requires the
approval of the holders of ordinary shares at the Extraordinary General Meeting
of the reduction of Saville's capital and certain other matters proposed in or
incidental to the Scheme.



    This Proxy Statement is being furnished to holders of ordinary shares,
including those represented by ADSs by directions given to the Depositary, and
holders of deferred shares (i) for the purposes of soliciting proxies by and on
behalf of Saville's Board of Directors for use at the Scheme Ordinary Meeting,
the Scheme Deferred Meeting and the Extraordinary General Meeting to be held at
10:00 a.m., 10:05 a.m. and 10:10 a.m. respectively, local time (or, in each
case, as soon thereafter as the relevant preceding Meeting has concluded or been
adjourned), on August 31, 1999 at The Great Southern Hotel, Shannon, County
Clare, Ireland, and at any adjournment thereof and (ii) to explain the effect of
the Scheme and to describe any material interests of the directors of Saville
and any effects which the Scheme will have upon them which are different from
the effects which it will have on others affected by the Scheme. This Proxy
Statement and the accompanying notices and proxy card(s) are first being mailed
on or about July 30, 1999 to holders of ordinary shares, including those
represented by ADSs, and deferred shares whose names appear on Saville's
register of shareholders at the time of mailing.


    The obligations of Saville and ADC to consummate the Acquisition are subject
to, among other things, the condition that the shareholders of Saville, by the
requisite votes thereof, approve the Scheme and the other matters to be proposed
at the Meetings. See "The Acquisition Agreement and the Scheme-- Conditions."

    The Board of Directors is not aware of any matters other than those set
forth in the Notices of the Meetings transmitted with this Proxy Statement that
may be brought before the Meetings.

    SHAREHOLDERS ARE REQUESTED PROMPTLY TO COMPLETE, DATE, SIGN AND RETURN THE
ACCOMPANYING SHAREHOLDERS' PROXY CARD(S) IN THE ENCLOSED POSTAGE-PAID ENVELOPE.

    SHAREHOLDERS SHOULD NOT FORWARD ANY CERTIFICATES (INCLUDING ADR
CERTIFICATES) REPRESENTING ORDINARY SHARES OR DEFERRED SHARES WITH THEIR PROXY
CARDS. IN THE EVENT THE ACQUISITION IS CONSUMMATED, CERTIFICATES SHOULD BE
DELIVERED IN ACCORDANCE WITH INSTRUCTIONS SET FORTH IN A LETTER OF TRANSMITTAL
WHICH WILL BE SENT TO SHAREHOLDERS PROMPTLY AFTER THE CONSUMMATION OF THE
ACQUISITION.

MATTERS TO BE CONSIDERED AT THE MEETINGS

    Each of the Scheme Ordinary Meeting and the Scheme Deferred Meeting has been
convened to consider and, if thought fit, approve the Scheme.

    The Extraordinary General Meeting has been convened to consider and, if
thought fit, pass a special resolution to approve the reduction of Saville's
capital and the subsequent creation and issuance by Saville of new shares to ADC
in accordance with the Scheme.


    It is also proposed, as part of the resolution to be considered at the
Extraordinary General Meeting, to amend Saville's articles of association to
ensure that ordinary shares issued upon the exercise of options or otherwise
between the commencement of the Scheme Ordinary Meeting and 5:00 p.m. on the day


                                       30
<PAGE>

before the Final Court Order is made will be subject to the Scheme. It is also
proposed to amend Saville's articles of association so that any ordinary shares
issued to any person other than ADC, its subsidiary undertakings or any person
on behalf of them at or after 5:00 p.m. on the day before the Final Court Order
is made will be automatically exchanged for shares of ADC common stock on the
same terms as under the Scheme. Part (ii) of the resolution set out in the
notice of the Extraordinary General Meeting included in this document seeks
shareholder approval for such amendments.


BOARD RECOMMENDATION

    The Board of Directors has determined by a unanimous vote of its
disinterested directors and a unanimous vote of all of its directors that the
Acquisition is fair to, and in the best interests of, Saville and its
shareholders and has approved the Acquisition, the Acquisition Agreement and the
Scheme. ACCORDINGLY, THE BOARD OF DIRECTORS RECOMMENDS THAT SHAREHOLDERS VOTE
"FOR" APPROVAL OF THE SCHEME, THE REDUCTION OF SAVILLE'S CAPITAL AND THE OTHER
MATTERS TO BE PROPOSED AT THE MEETINGS.

SHAREHOLDERS ENTITLED TO VOTE


    Each holder of record of ordinary shares is entitled to vote either in
person or by proxy at the Scheme Ordinary Meeting and will be entitled at that
Meeting to one vote for every ordinary share held by him. Voting will be by way
of a poll.



    Lawrence Barker, John J. Boyle III, Michael Durance, Susan Ernst, Eric
Fredine, Christopher Hanson and Robin Winn, each an executive officer of
Saville, have entered into employment agreements with ADC pursuant to which they
will receive, among other things, options to purchase shares of ADC common
stock. See "The Acquisition--Interests of Certain Persons in the Acquisition".
Accordingly, the interests of the Excluded Officers, each of whom owns ADSs,
differ or may differ from those of other persons owning ordinary shares, and the
Excluded Officers have therefore agreed to instruct the Depositary not to
exercise the voting rights attaching to the ordinary shares represented by the
ADSs owned by them and have agreed to be bound by the Scheme in respect of those
shares.



    Each holder of record of deferred shares, other than John J. Boyle III, is
entitled to vote either in person or by proxy at the Scheme Deferred Meeting and
will be entitled at that meeting to one vote for every deferred share held by
him. Voting will be by way of a poll. Mr. Boyle has entered into certain
employment and other agreements with ADC. See "The Acquisition--Interests of
Certain Persons in the Acquisition." As a result, Mr. Boyle, who owns deferred
shares, will not be entitled to vote at the Scheme Deferred Meeting but has
agreed to be bound by the Scheme in respect of those shares.



    Each holder of record of ordinary shares is entitled to vote in person or by
proxy at the Extraordinary General Meeting. On a show of hands, each shareholder
will have one vote, and on a poll, each shareholder will have one vote for each
ordinary share held by him.


VOTING SECURITIES


    As of the close of business on July 20, 1999, there were outstanding and
entitled to vote an aggregate of 39,213,951 ordinary shares and 30,000 deferred
shares of Saville.


QUORUM


    The Companies Act does not specify the quorum for the transaction of
business at the Scheme Ordinary Meeting or the Scheme Deferred Meeting. However,
Saville has been advised by McCann FitzGerald, its Irish counsel, that, unless
the High Court decides that the circumstances justify a different quorum, two
holders of record of ordinary shares or (as the case may be) deferred shares
(other than John J. Boyle III) entitled to vote at the relevant Meeting, each
appearing in person or by proxy, will


                                       31
<PAGE>
constitute a quorum for the transaction of business at the Scheme Ordinary
Meeting or (as the case may be) the Scheme Deferred Meeting.

    Three holders of record of ordinary shares, each appearing in person or
represented by proxy, will constitute a quorum for the transaction of business
at the Extraordinary General Meeting.

VOTES REQUIRED

    In order to consummate the Acquisition, the affirmative vote of shareholders
is required at each of the Scheme Ordinary Meeting, the Scheme Deferred Meeting
and the Extraordinary General Meeting.


    The Scheme must be approved at the Scheme Ordinary Meeting by (i) a majority
in number of those holders or ordinary shares present and voting in person or by
proxy and (ii) 75% in value of those holders of ordinary shares present and
voting in person or voting by proxy. The custodian of the Depositary is the
shareholder of record in respect of those ordinary shares represented by ADSs.



    As of July 20, 1999, executive officers, directors (other than the Excluded
Officers) and their affiliates beneficially owned an aggregate of 1,893,348
ordinary shares, or approximately 4.8% of the outstanding ordinary shares.



    The Scheme must be approved at the Scheme Deferred Meeting by (i) a majority
in number of those holders of deferred shares present and voting in person or by
proxy and (ii) 75% in value of those holders of deferred shares present and
voting in person or by proxy (other than John J. Boyle III, who for reasons
described above will not be entitled to vote at the Scheme Deferred Meeting but
has agreed to be bound by the Scheme in respect of those shares).



    As of July 20, 1999, executive officers, directors and their affiliates
(other than Mr. Boyle) beneficially owned 14,813 deferred shares, or
approximately 49.4% of the outstanding deferred shares. Mr. Boyle has agreed to
vote all the deferred shares owned by him in favor of the Scheme in his separate
vote as a holder of deferred shares.


    The resolution to be proposed at the Extraordinary General Meeting must, in
order to be passed, be approved by not less than 75% of the votes cast at the
Extraordinary General Meeting by the holders of ordinary shares. The custodian
of the Depositary is the shareholder of record in respect of those ordinary
shares represented by ADSs.


    Holders of shares that abstain from voting such shares and holders of ADRs
that instruct the Depositary not to vote the shares represented by ADSs which
their ADRs evidence as to a particular matter will not have such shares counted
as votes in favor of such matter, and such shares also will not be counted as
shares voted on such matter and may not count towards a quorum on such matter.
Accordingly, such abstentions will have no effect on the voting on the matters
presented for approval by the shareholders at any of the Meetings. Under the
terms of Saville's agreement with the Depositary, Saville shall be deemed to
have received a proxy to vote those ordinary shares represented by ADSs where,
the holders do not instruct the Depositary how to vote, including those ordinary
shares represented by ADSs held in "street name" by a broker or nominee who
indicates on a proxy that he does not have discretionary authority to instruct
the Depositary how to vote as to a particular matter. Saville intends to vote
all such ordinary shares represented by ADSs FOR the proposals presented at the
Meetings. Accordingly, broker non-votes will have the same effect as a vote for
the matters presented for approval at the Meetings.


NO RIGHT TO DISSENT

    If the shareholders of Saville approve the Scheme and the reduction of
Saville's capital in accordance therewith, and the High Court sanctions the
Scheme and confirms the reduction of Saville's capital, then, subject to the
Scheme becoming effective in accordance with its terms, each of Saville's
ordinary shares and deferred shares will be automatically deemed cancelled in
consideration for the right to receive that

                                       32
<PAGE>
number of shares of ADC common stock as determined by the Ordinary Share
Allotment Ratio or the Deferred Share Allotment Ratio, as the case may be, and
each Saville option will be automatically assumed and converted into an ADC
option as provided herein, and no holder of any of the foregoing securities will
have a right under Irish law to dissent or obtain the "full value" of, or
otherwise seek a court appraisal of the value of, such securities.

VOTING; PROXIES; REVOCATION OF PROXIES

    Voting at the Scheme Ordinary Meeting and the Scheme Deferred Meeting will
be by way of a poll (I.E. a written vote). Voting at the Extraordinary General
Meeting will be by way of a show of hands unless a poll is duly demanded.
Pursuant to Saville's agreement with the Depositary, the Depositary or its
authorized representative will demand a poll for each matter proposed at the
Extraordinary General Meeting. In the case of each Meeting, votes may be given
either personally or by proxy. In the case of the Scheme Ordinary Meeting and
the Scheme Deferred Meeting, each shareholder present in person or by proxy will
be entitled to one vote for each ordinary share or (as the case may be) deferred
share held by him. In the case of the Extraordinary General Meeting, on a show
of hands each holder of ordinary shares present in person or by proxy will have
one vote but so that no individual can have more than one vote and on a poll
each holder of ordinary shares will have one vote for each share held by him.
Where there is an equality of votes at the Extraordinary General Meeting, the
Chairman of the meeting is entitled to a casting vote in addition to any other
vote he may have.


    To be valid, a proxy form for any of the Meetings must be deposited not less
than 48 hours prior to the time appointed for the holding of that Meeting at the
offices of Saville's Registrar, Computer Share Services (Ireland) Limited, Heron
House, Corrig Road, Sandyford Industrial Estate, Dublin 18 or the registered
office of Saville, IDA Business Park, Dangan, Galway, Ireland, or, in the case
of the Scheme Ordinary Meeting or the Scheme Deferred Meeting, delivered to the
Chairman of the relevant Meeting at such Meeting. Any proxy may be revoked at
any time by a shareholder before it is voted by:


    - voting in person at the relevant Meeting (although mere personal
      attendance at the relevant Meeting will not constitute a revocation of a
      proxy);


    - delivery of a subsequently dated proxy to either of the above offices,
      provided that such subsequently dated proxy must be received at either of
      the above offices not less than 48 hours prior to the time appointed for
      holding of the relevant Meeting or, in the case of the Scheme Ordinary
      Meeting or the Scheme Deferred Meeting, delivered to the Chairman of the
      relevant Meeting at such Meeting; or


    - delivery of written revocation of such proxy, provided that such
      revocation must be received at either of the above offices not less than
      one hour prior to the time appointed for the holding of the relevant
      Meeting.


    The custodian of the Depositary is the shareholder of record in respect of
those ordinary shares represented by ADSs. Saville has requested the Depositary,
and the Depositary is required pursuant to Saville's agreement with the
Depositary, to mail to all owners of ADRs evidencing ADSs of Saville (the
"Owners") a notice, the form of which notice will be in the sole discretion of
the Depositary, containing (a) the information included in the notice of meeting
received by the Depositary from Saville, (b) a statement that the Owners as of
the close of business on a specific record date will be entitled, subject to any
applicable provision of Irish law and of the Memorandum and Articles of
Association of Saville, to instruct the Depositary as to the exercise of the
voting rights, if any, pertaining to the amount of ordinary shares or other
deposited securities represented by their respective ADSs, (c) a statement that
Owners who instruct the Depositary as to the exercise of their voting rights
will be deemed to have instructed the Depositary or its authorized
representative to call for a poll (I.E., a written vote) with respect to each
matter for which instructions are given, subject to any applicable provisions of
Irish law and of Saville's Memorandum and Articles of Association and (d) a
statement as to the manner in which such instructions


                                       33
<PAGE>
may be given, including an express indication that instructions may be given or
deemed given to the Depositary to give a discretionary proxy to a person
designated by Saville, as described in the next paragraph. Upon the written
request of an Owner, received on or before the date established by the
Depositary for such purpose, the Depositary will endeavor, insofar as
practicable, to vote or cause to be voted the amount of ordinary shares or other
deposited securities represented by the ADSs evidenced by such Owner's ADRs in
accordance with the nondiscretionary instructions set forth in such request.
Accordingly, pursuant to Saville's Memorandum and Articles of Association and
applicable Irish law, the Depositary will cause its authorized representative to
attend the Extraordinary General Meeting and call for a poll as instructed in
accordance with clause (c) above for the purpose of effecting such vote. The
Depositary will not vote or attempt to exercise the right to vote that attaches
to the ordinary shares or other depositary securities, other than in accordance
with such instructions or deemed instructions received.


    The Deposit Agreement provides that if no instructions are received by the
Depositary from any Owner with respect to any of the deposited securities
represented by the ADSs evidenced by such Owner's ADRs (including those ADSs
held in "street name" by a broker or nominee who indicates on a proxy that he or
she does not have discretionary authority to vote as to a particular matter) on
or before the date established by the Depositary for such purpose, the
Depositary will deem such Owner to have instructed the Depositary to give, and
the Depositary will give, a discretionary proxy to a person designated by
Saville to vote such deposited securities, under circumstances and according to
the terms as set forth in the Deposit Agreement. Saville intends to vote all
ordinary shares represented by such ADSs FOR the proposals presented at the
Meetings.


SOLICITATION OF PROXIES


    Saville will bear the costs of soliciting proxies in the accompanying forms
from shareholders. In addition to soliciting proxies by mail, directors,
officers and employees of Saville, without receiving additional compensation
therefor, may solicit proxies by telephone, by telegram or in person.
Arrangements will be made with brokerage firms and other custodians, nominees
and fiduciaries to forward solicitation materials to the beneficial owners of
ordinary shares (or ADSs) held of record by such persons, and Saville will
reimburse such brokerage firms, custodians, nominees and fiduciaries for
reasonable out-of-pocket expenses incurred by them in connection therewith.

                                THE ACQUISITION

BACKGROUND OF THE ACQUISITION


    Over the past year, Saville has been approached at various times by other
companies in the telecommunications industry about the possibility of pursuing
various business combinations. Saville has from time to time reviewed its
position in its industry with respect to potential expansion of operations into
new markets, competition and consolidation in the industry and the goal of
maximizing shareholder value. In January 1999, the Board of Directors authorized
a subcommittee of the Board of Directors of Saville (made up of John A.
Blanchard, III, Brian E. Boyle, John J. Boyle III and John W. Sidgmore) to
initially evaluate and respond to certain proposals brought to the attention of
Saville for a business combination. In addition, in January 1999, the Board
authorized Saville to retain Morgan Stanley as financial advisor in connection
with possible business combinations.


    On January 29, 1999, Morgan Stanley was formally retained by Saville to
advise it on potential business combinations.


    In the course of the past several months, Saville has had ongoing
discussions, at varying levels of intensity, with ADC (commencing on March 18,
1999) and certain other potential acquirors with respect to the possible
acquisition of Saville. These discussions were prompted by, on the one hand,
increased consolidation in Saville's industry, a desire to accelerate Saville's
basic longer term growth strategy and a desire to better serve the needs of
existing and prospective customers and, on the other hand, with respect to ADC,
ADC's desire to further enhance its multi-service network strategy by expanding
its communications software solutions with that offered by Saville. On March 22,
1999, a confidentiality agreement was entered into between Saville and ADC.
Saville also entered into similar agreements with other potential acquirors.



    During certain periods beginning on March 31, 1999 and continuing in April
and May 1999, discussions were held primarily between John J. Boyle III,
Chairman, Chief Executive Officer and then President of Saville and William J.
Cadogan, Chairman, Chief Executive Officer and President of ADC, with respect to
a potential acquisition of Saville by ADC. Mr. Boyle also held similar
discussions with a selected group of other potential acquirors during this time.



    On April 19, 1999, ADC delivered a letter to Saville expressing its interest
in an acquisition of Saville at a price of $17.50 per share. Other potential
acquirors also expressed interest. During the week of April 19, 1999, a group of
members of ADC's senior management and legal advisors met with the senior
management of Saville to conduct a business, financial, legal and technical due
diligence review of Saville. Saville also had similar meetings with the other
potential acquirors at that time. In the discussions held between Saville and
ADC and between Saville and the other potential acquirors after such meetings,
the parties did not reach an agreement with respect to the terms of the proposed
acquisition.


    In early May 1999, various telephone conversations were held among ADC,
Saville and their respective financial advisors with respect to a potential
acquisition. Based on a telephone conversation between representatives of
Saville and ADC held on May 13, 1999, the parties agreed to proceed with
intensified negotiations toward a goal of a transaction at a per share price of
$17.50.

    On May 27, 1999, ADC's legal counsel provided a draft acquisition agreement
to Saville and its legal counsel. Commencing on May 27, 1999, and continuing
through June 19, 1999 representatives of Saville and ADC and their respective
financial advisors and legal counsel proceeded to negotiate the terms of the
Scheme and the Acquisition Agreement.


    On June 12, 1999, a special meeting of the Board of Directors of Saville was
held in order to discuss the possibility of a sale of all of the shares of
Saville. John J. Boyle III updated the members of Saville's Board on the
developments in the discussions with ADC and described the terms of the proposed


                                       35
<PAGE>
transaction. No formal action was taken at such meeting; however, Saville's
management was requested to continue to work toward a definitive agreement.


    On June 18, 1999, the Board of Directors of ADC held a special meeting and
considered the proposed Acquisition Agreement and the transactions contemplated
thereby, including the Scheme. Members of ADC's management and representatives
of Credit Suisse First Boston, ADC's financial advisor, each made presentations
to the ADC Board concerning the terms of the proposed transaction. Following
significant discussion, the Board of Directors of ADC concluded that the
Acquisition Agreement and the Scheme were in the best interests of ADC, and
approved the Scheme and the formula for determining the Allotment Ratios,
subject to the finalization of the transaction documents, and authorized the
officers of ADC to enter into the Acquisition Agreement and related agreements.


    On June 18, 1999, the Board of Directors of Saville held a special meeting
to consider the proposed Acquisition Agreement and the transactions contemplated
thereby, including the Scheme. At such meeting certain members of Saville's
management and its legal counsel made presentations regarding various aspects of
the proposed transaction. Morgan Stanley reviewed with the Board of Directors
the financial analyses performed by Morgan Stanley in connection with its
evaluation of the Ordinary Share Allotment Ratio. Morgan Stanley also rendered
to the Board an oral opinion (which opinion was subsequently confirmed by
delivery of a written opinion dated June 18, 1999) to the effect that, as of the
date of such opinion and based upon and subject to certain matters stated
therein, the Ordinary Share Allotment Ratio as set forth in the Scheme was fair,
from a financial point of view, to the holders of Saville's ordinary shares.

    In the meeting, the Board of Directors of Saville resolved to approve and
authorize the Acquisition Agreement and the Scheme. The resolution was adopted
both by a unanimous vote of all disinterested directors and by a unanimous vote
of all members of the Board, including the interested directors. Thereafter,
Saville and ADC executed the Acquisition Agreement and issued a joint press
release announcing the execution of the Acquisition Agreement.

SAVILLE'S REASONS FOR THE ACQUISITION

    Saville's Board of Directors has determined, both by a unanimous vote of its
disinterested directors and by a unanimous vote of all directors, that the
Acquisition Agreement and the Scheme are fair to and in the best interests of
Saville and its shareholders and has by such votes approved the Acquisition
Agreement and the Scheme. Accordingly, the Board of Directors recommends that
shareholders vote FOR approval of the Scheme, the reduction of Saville's capital
and the other matters to be proposed at the Meetings.

    In reaching its determination, the Board of Directors considered a number of
factors, including, without limitation, the following:

        (1) the effectiveness of the Acquisition in implementing and
    accelerating Saville's basic longer term growth strategy;

        (2) the present and anticipated environment of the telecommunications
    and energy billing industry, including the ability of Saville to compete
    effectively as an independent company, the growing consolidation in the
    industry and the position of Saville within the industry which led the Board
    of Directors to conclude that Saville would be in a better position to
    compete within the industry as part of a larger, better-capitalized entity;

        (3) the expectation that the operations of the combined company will be
    better able to serve the needs of customers, which typically seek a single
    supplier for "a complete solution" rather than multiple suppliers, and the
    expectation that the combined company will be better able to take advantage
    of marketing opportunities;

                                       36
<PAGE>
        (4) the impact of the economic fluctuations in various markets targeted
    by Saville, on the ability of Saville to meet its desired levels of revenues
    in the future;


        (5) the historical market prices and trading information with respect to
    the ordinary shares, and that (based on the closing price of the ADC common
    stock as of June 18, 1999) the 0.358 share of ADC common stock to be issued
    in consideration for each ordinary share represents (i) a premium of
    approximately 14.9% over the $15.625 closing price of the ADRs on the Nasdaq
    National Market on June 18, 1999, the last day prior to the public
    announcement of the execution of the Acquisition Agreement and (iii) a
    premium of approximately 115.9% over the $8.3125 closing price of the ADRs
    on the Nasdaq National Market, 45 trading days prior to the date on which
    the Ordinary Share Allotment Ratios was fixed, which led the directors to
    conclude that the Acquisition would provide an opportunity for shareholders
    to receive a significant premium to current and recent trading prices for
    the ordinary shares;


        (6) the expectations of management with respect to Saville's future
    growth and the opportunities for accelerated growth resulting from the
    acquisition and the indications made by ADC with respect to its intention to
    grow Saville's business in the future;

        (7) the opportunity of the optionholders to participate in the combined
    company through the conversion of Saville options into ADC options;

        (8) the financial condition, result of operations, business and
    prospects of Saville, including the nature of the markets in which Saville
    operates and its position in such markets, which helped the directors
    evaluate whether the Acquisition is in the best interests of Saville and
    whether it is an appropriate time to engage in the proposed transaction;

        (9) the expectation that the Acquisition will be a tax-free transaction
    to Saville and its shareholders and will be accounted for as a pooling of
    interests transaction under U.S. GAAP;

        (10) the likelihood of the Acquisition being approved by the appropriate
    regulatory authorities;

        (11) the terms and conditions of the Acquisition Agreement and the
    Scheme, including the amount and form of the consideration to be received by
    the shareholders and the optionholders and the conditions to the closing of
    the transaction, which led the directors to conclude that there was a high
    possibility that the Acquisition would be consummated;

        (12) the financial presentation of Morgan Stanley to the Board of
    Directors of Saville, including Morgan Stanley's oral opinion (which opinion
    was subsequently confirmed by delivery of a written opinion dated June 18,
    1999) to the effect that, as of the date of such opinion and based upon and
    subject to certain matters stated therein, the Ordinary Share Allotment
    Ratio, as set forth in the Scheme, was fair, from a financial point of view,
    to such holders of Saville's ordinary shares; and


        (13) in its determination that the Deferred Share Allotment Ratio is
    fair, from a financial point of view, to the holders of Saville's deferred
    shares, the Directors had regard to the limited rights attaching to the
    deferred shares, which: (i) do not entitle their holders to any dividends or
    to receive notice of or to attend or vote at general meetings, (ii) Saville
    is entitled to acquire at any time for no consideration and (iii) on a
    liquidation entitle their holders to a payment of IRL1.00 per share but only
    if every holder of ordinary shares has been paid, in addition to the amount
    paid up on such ordinary shares, an additional sum of $100,000 for every
    $0.000025 paid up on each ordinary share held by him.


    The foregoing discussion of the information and factors considered by
Saville's Board of Directors is not meant to be exhaustive but includes the
material factors considered by the Board of Directors. Saville's Board of
Directors did not quantify or attach any particular weight to the various
factors that it considered in reaching its determination that the Acquisition
Agreement and the Scheme are fair to and in the best interests of Saville. As a
result of its consideration of the foregoing and other relevant considerations,
the

                                       37
<PAGE>
Board of Directors determined by a unanimous vote of its disinterested directors
and by a unanimous vote of all directors that the Acquisition Agreement and the
Scheme are fair to and in the best interests of Saville and its shareholders and
approved the Acquisition Agreement and the Scheme. In considering the
recommendation of the Board of Directors with respect to the Acquisition,
shareholders should be aware that the interests of certain directors and
executive officers with respect to the Acquisition are or may be different from
or in addition to the interests of Saville and its shareholders generally. The
Board of Directors was aware of these interests, and took these interests into
account in approving the Acquisition Agreement, the Scheme and the transactions
contemplated thereby. See "--Interests of Certain Persons in the Acquisition."

    ACCORDINGLY, THE BOARD OF DIRECTORS RECOMMENDS THAT SHAREHOLDERS VOTE "FOR"
APPROVAL OF THE SCHEME, THE REDUCTION OF SAVILLE'S CAPITAL AND THE OTHER MATTERS
TO BE PROPOSED AT THE MEETINGS.

OPINION OF SAVILLE'S FINANCIAL ADVISOR


    Morgan Stanley & Co. Incorporated was retained by Saville to act as
financial advisor in connection with the Scheme. Morgan Stanley was selected by
Saville based on its qualifications and expertise in the industry. At the June
18, 1999 meeting of the Saville Board, Morgan Stanley rendered its oral opinion,
subsequently confirmed in writing, that, as of June 18, 1999 and based upon and
subject to the various considerations set forth in its opinion, the Ordinary
Share Allotment Ratio as set forth in the Scheme is fair from a financial point
of view to holders of Saville's ordinary shares.


THE FULL TEXT OF MORGAN STANLEY'S WRITTEN OPINION DATED JUNE 18, 1999, WHICH
SETS FORTH, AMONG OTHER THINGS, ASSUMPTIONS MADE, PROCEDURES FOLLOWED, MATTERS
CONSIDERED AND THE LIMITATIONS ON THE SCOPE OF THE REVIEW UNDERTAKEN, IS
ATTACHED AS ANNEX C TO THIS PROXY STATEMENT. HOLDERS OF ORDINARY SHARES ARE
URGED TO, AND SHOULD, READ THE OPINION CAREFULLY AND IN ITS ENTIRETY. MORGAN
STANLEY'S OPINION IS DIRECTED TO SAVILLE'S BOARD OF DIRECTORS AND ADDRESSES THE
FAIRNESS OF THE ORDINARY SHARE ALLOTMENT RATIO AS SET FORTH IN THE SCHEME FROM A
FINANCIAL POINT OF VIEW TO THE HOLDERS OF ORDINARY SHARES AND IT DOES NOT
ADDRESS ANY OTHER ASPECT OF THE SCHEME NOR DOES IT CONSTITUTE A RECOMMENDATION
TO ANY HOLDER OF ORDINARY SHARES OR DEFERRED SHARES AS TO HOW TO VOTE AT THE
MEETINGS. THE SUMMARY OF THE OPINION OF MORGAN STANLEY SET FORTH IN THIS PROXY
STATEMENT IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF ITS
OPINION.


    In connection with rendering its opinion, Morgan Stanley, among other
things:



    - reviewed certain publicly available financial statements and other
      business and financial information of Saville and ADC, respectively;


    - reviewed certain internal financial statements and other financial and
      operating data concerning Saville and ADC prepared by the managements of
      Saville and ADC, respectively;

    - discussed certain financial projections prepared by the managements of
      Saville and ADC, respectively;

    - discussed the past and current operations and financial condition and the
      prospects of Saville, including information relating to certain strategic,
      financial and operational benefits anticipated from the Scheme, with
      senior executives of Saville;

    - discussed the past and current operations and financial condition and the
      prospects of ADC with senior executives of ADC;

                                       38
<PAGE>
    - reviewed the pro forma impact of the Scheme on ADC's earnings per share
      and other financial ratios;

    - reviewed the reported prices and trading activity for the ADRs;

    - discussed with the senior managements of Saville and ADC certain research
      analyst projections for Saville and ADC, respectively;

    - compared the financial performance of Saville and ADC and the prices and
      trading activity of Saville's ADRs and ADC's common stock with that of
      certain other publicly-traded companies and their securities;

    - reviewed the financial terms, to the extent publicly available, of certain
      acquisition transactions deemed relevant;

    - participated in discussions and negotiations among representatives of
      Saville and ADC and their financial and legal advisors;

    - reviewed the June 17, 1999 draft of the Acquisition Agreement and certain
      related documents; and

    - considered such other factors as Morgan Stanley deemed appropriate.


    In arriving at its opinion, Morgan Stanley assumed and relied upon, without
independent verification, the accuracy and completeness of the information
reviewed by it for the purposes of its opinion. With respect to the internal
financial statements and other financial and operating data and discussions
relating to strategic, financial and operational benefits anticipated from the
Scheme provided by Saville and ADC, Morgan Stanley assumed that they have been
reasonably prepared on bases reflecting the best currently available estimates
and judgments of the prospects of Saville and ADC, respectively. Morgan Stanley
relied upon the assessment by the managements of Saville and ADC of their
ability to retain key employees of Saville. Morgan Stanley also relied upon,
without independent verification, the assessment by the managements of Saville
and ADC of (i) the strategic and other benefits expected to result from the
Scheme, (ii) Saville's and ADC's technologies and products, (iii) the timing and
risks associated with the integration of Saville with ADC, and (iv) the validity
of, and risks associated with, Saville's and ADC's existing and future products
and technologies. Morgan Stanley did not make any independent valuation or
appraisal of the assets or liabilities or technology of Saville or ADC, nor had
Morgan Stanley been furnished with any such appraisals. In addition, Morgan
Stanley assumed that the Scheme will be accounted for as a
"pooling-of-interests" business combination in accordance with U.S. GAAP and the
Scheme will be treated as a tax-free reorganization and/or exchange pursuant to
the U.S. Internal Revenue Code of 1986, as amended, and will be consummated in
accordance with the terms set forth in the Acquisition Agreement and the Scheme.
Morgan Stanley's opinion is necessarily based on financial, economic, market and
other conditions as in effect on, and the information made available to Morgan
Stanley as of the date of its opinion.


    The following is a brief summary of certain analyses performed by Morgan
Stanley in connection with its oral opinion and the preparation of its written
opinion letter dated June 18, 1999. Certain of these summaries of financial
analyses include information presented in tabular format. In order to fully

    All earnings and growth estimates are based on the estimates from securities

    No company utilized in the peer group comparison analysis as a comparison is
identical to Saville or ADC. In evaluating the peer groups, Morgan Stanley made
judgments and assumptions with regard to industry performance, general business,
economic, market and financial conditions and other matters,

many of which are beyond the control of Saville or ADC, such as the impact of
competition on the business of Saville or ADC and the industry generally,
industry growth and the absence of any material adverse change in the financial
condition and prospects of Saville or ADC or the industry or in the financial
markets in general. Mathematical analysis (such as determining the average or
median) is not in itself a meaningful method of using peer group data.

    ANALYSIS OF SELECTED PRECEDENT TRANSACTIONS.  Morgan Stanley reviewed a
number of telecommunications software transactions and compared certain
statistics for the telecommunications software transactions to the relevant
financial statistics for Saville based on the value of Saville implied by the
Ordinary Share Allotment Ratio and the closing price for Saville's ADRs and
ADC's common stock as of June 16, 1999. The following table presents the implied
values, using the low, median and high multiples of next twelve months'
estimated earnings, the 45 trading day prior to announcement offer price
premiums, the 45 trading day prior exchange ratios and the 60 trading day
average exchange ratios for the telecommunications software transactions,
compared to the respective earnings multiple and offer price premium and
Ordinary Share Allotment Ratio for the transaction implied by the offer as of
June 16, 1999.

- ------------------------

(1) Based on analysts' estimates.

    No transaction utilized as a comparison in the precedent transactions
analysis is identical to the Acquisition Agreement and the Scheme. In evaluating
the precedent transactions, Morgan Stanley made judgments and assumptions
regarding industry performance, general business, economic, market and financial
conditions and other matters, many of which are beyond the control of Saville or
ADC, such as the impact of competition on Saville or ADC and the industry
generally, industry growth and the absence of any material adverse change in the
financial condition and prospects of Saville or ADC or the industry or in the
financial markets in general. Mathematical analysis (such as determining the
average or median) is not in itself a meaningful method of using comparable
transaction data.

    DISCOUNTED EQUITY ANALYSIS.  Morgan Stanley reviewed the present value per
share of Saville's respective future trading prices based on ranges of the
following assumptions: earnings per share estimates for the calendar year 2000
and the calendar year 2002; illustrative multiples of earnings per share,
ranging from 12.0x to 16.0x; and illustrative discount rates ranging form 18.0%
to 22.0%. Based on these assumptions, Morgan Stanley calculated the present
value of future theoretical trading values, ranging from approximately $8.00 to
$17.00 per Saville share.


    PRO FORMA ANALYSIS OF THE SCHEME.  Morgan Stanley analyzed the pro forma
impact of the Scheme on earnings per share for ADC for calendar years 1999
through 2000. The pro forma results were calculated as if the Scheme had closed
at the beginning of calendar 1999, and were based on projected earnings derived
from First Call Estimates. The pro forma analysis also took into account the
pooling accounting assumptions and followed U.S. GAAP in deriving earnings.
Morgan Stanley noted that, without including synergies, on a U.S. GAAP basis,
the Scheme would be slightly dilutive to ADC's earnings per share in calendar
1999 and accretive to ADC's earnings per share in calendar 2000.


                                       41
<PAGE>
    The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to a partial analysis or summary description. In
arriving at its opinion, Morgan Stanley considered the results of all of its
analyses as a whole and did not attribute any particular weight to any
particular analysis or factor considered by it. Furthermore, Morgan Stanley
believes that selecting any portion of Morgan Stanley's analyses, without
considering all analyses, would create an incomplete view of the process
underlying Morgan Stanley's opinion. In addition, Morgan Stanley may have deemed
various assumptions more or less probable than other assumptions, so that the
ranges of valuations resulting from any particular analysis described above
should not be taken to be Morgan Stanley's view of the actual value of Saville
or ADC.

    In performing its analysis, Morgan Stanley made numerous assumptions with
respect to industry performance, general business and economic conditions and
other matters, many of which are beyond the control of Saville or ADC. The
analyses performed by Morgan Stanley are not necessarily indicative of actual
values, which may be significantly more or less favorable than suggested by such
analyses. Such analyses were prepared solely as a part of Morgan Stanley's
analysis of the fairness from a financial point of view of the Ordinary Share
Allotment Ratio as set forth in the Scheme and were provided to Saville's Board
of Directors in connection with the delivery of Morgan Stanley's opinion. The
analyses do not purport to be appraisals of value or to reflect the prices at
which Saville or ADC might actually be sold. In addition, as described above,
Morgan Stanley's opinion was one of the many factors taken into consideration by
Saville's Board of Directors in making its determination to approve the
Acquisition. The Ordinary Share Allotment Ratio pursuant to the Scheme was
determined through arms'-length negotiations between Saville and ADC and was
approved by Saville's Board of Directors.

    Morgan Stanley is an internationally recognized investment banking and
advisory firm. Morgan Stanley, as part of its investment banking business, is
regularly engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions, negotiated underwritings, competitive
biddings, secondary distributions of listed and unlisted securities, private
placements and valuations for corporate, estate and other purposes. In the
ordinary course of its trading, brokerage and financing activities, Morgan
Stanley and its affiliates may, at any time, have a long or short position in,
and buy and sell the debt or equity securities and senior loans of Saville or
ADC for its account or the account of its customers.

    Pursuant to an engagement letter dated January 29, 1999, Saville has agreed
to pay Morgan Stanley (i) an advisory fee which is payable in the event that the
Scheme is not completed, and (ii) if the Scheme is completed, a transaction fee
of approximately $5,000,000. Saville has also agreed to reimburse Morgan Stanley
for all expenses incurred in connection with the services provided by Morgan
Stanley. Saville has agreed to indemnify Morgan Stanley and its affiliates,
their respective directors, officers, agents and employees, and each person, if
any, controlling Morgan Stanley or any of its affiliates against certain
liabilities and expenses, including liabilities under the federal securities
laws arising out of or in connection with Morgan Stanley's engagement and any
related transactions.

THE HIGH COURT SANCTION HEARING


    The hearing by the High Court of Saville's application for the sanction of
the Scheme and the confirmation of the proposed reduction of capital will take
place on a day which will be appointed by the High Court following a separate
application for that purpose. At the same time as the High Court appoints the
day for hearing, it will direct how the date of the hearing should be
advertised. Saville will propose that such advertising should be placed in the
legal notices sections (or similar available alternative section) in the Wall
Street Journal and The Irish Times newspapers. All holders of ordinary shares
and of deferred shares are entitled to attend and be heard at the hearing in
person or through a professional lawyer. Submissions and arguments to the High
Court are generally made orally, but any facts other than those expressed in
Saville's own documents which a person wishes to put forward must be put forward
as evidence in the form of a sworn written statement (an "affidavit" being the
standard form for this in Irish practice). Any person proposing to make
submissions or put forward evidence to the High Court at the hearing will be
requested to advise Saville's Irish lawyers in advance and they in turn will
advise the High Court. Individuals may make these submissions personally or by a
professional lawyer entitled to appear in High Court in Ireland (a "solicitor"
or "barrister" in Irish practice).



    The hearing will take place on the advertised date or on adjourned dates
then fixed by the High Court. The High Court will consider the submissions and
evidence presented to it so as to establish whether the requirements of Irish
law and Saville's corporate constitution (its `memorandum and articles of
association') so far as these are applicable have been complied with, whether
the necessary majorities of Saville's shareholders of record have voted in
favour of approving the Scheme and the resolution for the reduction of Saville's
capital, and whether the Scheme and reduction of capital are fair and reasonable
in all circumstances. The High Court may announce its decision immediately after
the hearing or may defer this until a date to be announced later.



EFFECTIVE TIME OF THE ACQUISITION



    The Acquisition will be consummated upon delivery to the Registrar of
Companies in Dublin, Ireland, of a copy of the final order of the High Court
sanctioning the Scheme and confirming the reduction of Saville's capital, and
the registration by the Registrar of the order confirming the reduction of
Saville's capital.


INTERESTS OF CERTAIN PERSONS IN THE ACQUISITION

    In considering the recommendation of the Board of Directors with respect to
the Scheme, shareholders of Saville should be aware that certain executive
officers and directors of Saville have certain interests in the Acquisition that
may be substantial or in addition to the interests of shareholders of Saville
generally. The disinterested directors of the Board and the Board of Directors
were aware of these interests and considered them, among other factors, in
approving the Acquisition Agreement and the Scheme. The interests are summarized
below.

    INTERESTS OF EXECUTIVE OFFICERS


    INTERESTS IN ORDINARY SHARES.  As of July 20, 1999, the executive officers
of Saville and their respective affiliates (other than John J. Boyle III whose
shares are included in the director totals described below), beneficially owned
an aggregate of 12,966 ordinary shares, which will be treated in the same manner
as ordinary shares held by other shareholders. The executive officers of Saville
and their respective affiliates will receive an aggregate of 4,641 shares of ADC
common stock in the Acquisition. See "Security Ownership of Management and
Certain Other Beneficial Owners" on pages 59 to 62.



    INTERESTS IN SAVILLE OPTIONS.  Certain executive officers of Saville hold
Saville options. As of July 20, 1999, the executive officers of Saville and
their respective affiliates (other than John J. Boyle III whose


                                       43
<PAGE>

options are included in the director totals below), held Saville options to
purchase an aggregate of 1,587,335 ordinary shares that will be treated in the
same manner as Saville options held by other optionholders. Of the Saville
options held by executive officers, 407,333 were vested and 1,180,002 were
unvested as of July 20, 1999. All unvested Saville options, including those held
by Saville's executive officers and their respective affiliates, will become
exercisable in full upon completion of the Acquisition. See "Security Ownership
of Management and Certain Other Beneficial Owners" on pages 59 to 62.



    EMPLOYMENT AGREEMENTS.  Lawrence S. Barker, Michael Durance, Susan Ernst,
Eric Fredine, Christopher Hanson and Robin Winn, all of whom are executive
officers of Saville, each have entered into an Employment Agreement with ADC,
which will take effect on the business day following the Effective Time. Other
than Mr. Hanson's Employment Agreement which has a six-month term, each
Employment Agreement has a two-year term, which will end on the last day of the
month in which falls the two-year anniversary of the effective date of such
agreement. Each Employment Agreement provides for an annual base salary, stock
option grants, bonus arrangements and other benefits. In addition, Saville has
paid each such executive a retention bonus of 50% of his or her current base
salary (25% in the case of Mr. Hanson), which amount must be repaid by the
executive in the event the executive is not an employee of Saville at the
Effective Time, and ADC has agreed to pay each such executive an additional
retention bonus of 50% of his or her current base salary (25% in the case of Mr.
Hanson) within thirty days of the Effective Time. ADC will also pay the
executive a specified amount equal to 100% of the amount of the target bonus the
executive might have earned under the incentive bonus plan established by
Saville for the 1999 calendar year. This bonus payment will be made within 60
days after the end of the 1999 calendar year, provided the executive is employed
by ADC on the date the payment is to be made. The executive will also be
eligible to participate in any management incentive plan ("MIP") ADC establishes
for any fiscal year, according to the targets and guidelines, and the terms and
conditions ADC establishes to govern the MIP for that fiscal year. ADC will
recommend to ADC's Compensation and Organization Committee that the executive be
granted options to purchase shares of ADC common stock, in accordance with the
terms of the ADC 1991 Stock Incentive Plan and a stock option agreement to be
entered into by the executive. Each year during the term of the Employment
Agreement, the executive will be eligible to participate in ADC's executive
stock option plan for such year. In addition, as a further incentive for the
executive to contribute to the effective performance of ADC's Software Systems
Division, ADC will recommend to the ADC Compensation and Organization Committee
that the executive be granted an option to purchase additional shares of ADC's
common stock. The vesting of this option (the "Performance Option") will be
contingent upon the Software Systems Division of ADC meeting the financial
performance goals ADC establishes for the Software Systems Division for each
fiscal year. Upon the termination of the executive's employment by ADC for any
reason, all Performance Options that have not yet vested will expire and the
executive will have no right to exercise those options. The Employment Agreement
also provides that if the executive's employment is terminated either (i) by ADC
with Cause (as defined in the Employment Agreement) or (ii) upon the death or
disability of the executive, then the executive will not be entitled to receive
any further compensation after the date of termination, subject to applicable
law. If ADC terminates the executive's employment without cause, ADC shall pay
to the executive as severance pay an amount equal to the executive's annual base
salary on the termination date, computed on a monthly basis, multiplied by
twelve (12) months and a pro rata portion of the incentive target percentage for
the fiscal year in effect when the termination is effective.



    John J. Boyle III, Saville's Chairman of the Board and Chief Executive
Officer, has also entered into an Employment Agreement and a Restricted Stock
Rollover Agreement with ADC as described below.


    SEVERANCE ARRANGEMENTS


    Each executive officer (other than the executive officers who have entered
into employment agreements with ADC as described above) and certain other
officers of Saville (for a combined total of 20 officers) will become eligible
for certain severance payments under specified conditions from ADC upon


                                       44
<PAGE>

consummation of the Acquisition. Pursuant to these severance arrangements, ADC
would be obligated to pay 12 months' base salary to any such person whose
employment with ADC is terminated within 12 months after the Effective Time by
ADC without Cause (as defined in the severance arrangement) or by the employee
for Good Reason (as defined in the severance arrangement).


    INTERESTS OF DIRECTORS


    INTERESTS IN ORDINARY SHARES.  As of July 20, 1999, the directors of Saville
and their respective affiliates beneficially owned an aggregate of 1,937,582
ordinary shares, which will be treated in the same manner as ordinary shares
held by other shareholders. The directors of Saville and their respective
affiliates will receive an aggregate of 693,654 shares of ADC common stock in
the Acquisition. See "Security Ownership of Management and Certain Other
Beneficial Owners" on pages 59 to 62.



    INTERESTS IN SAVILLE OPTIONS.  Certain directors of Saville hold Saville
options. As of July 20, 1999, the directors of Saville and their respective
affiliates, held Saville options to purchase an aggregate of 1,517,000 ordinary
shares that will be treated in the same manner as Saville options held by other
optionholders. Of the Saville options held by directors, 1,260,334 were vested
and 256,666 were unvested as of July 20, 1999. All unvested Saville options,
including those held by Saville's directors and their respective affiliates,
will become exercisable in full upon completion of the Acquisition. See
"Security Ownership of Management and Certain Other Beneficial Owners" on pages
59 to 62.



    EMPLOYMENT AGREEMENTS.  John J. Boyle III, Saville's Chairman of the Board
and Chief Executive Officer, has entered into an Employment Agreement with ADC
on substantially the same terms as those of the executive officers described in
the preceding subsection, with the following exceptions: the employment
agreement will terminate six months after the first business day following the
Effective Time; Mr. Boyle will serve as a Senior Vice President of ADC; Mr.
Boyle will receive an annualized salary of $380,000; on the date Mr. Boyle's
Employment Agreement takes effect, ADC will grant to Mr. Boyle 6,000 shares of
ADC Restricted Stock (which shall fully vest in favor of Mr. Boyle if he is
employed by ADC on the date the Employment Agreement terminates, and which grant
shall become null and void if Mr. Boyle's employment is terminated for any
reason before the end of the term of the Employment Agreement); and ADC may
terminate Mr. Boyle at any time and for any reason, and without notice, provided
ADC pays to Mr. Boyle his base salary for the remaining period of the term of
the Employment Agreement, a severance payment of $300,000 and a special
incentive payment in the amount of $125,000.



    STOCK RESTRICTION AGREEMENT.  John J. Boyle III, Saville's Chairman of the
Board and Chief Executive Officer, is party to a Stock Restriction Agreement
with Saville dated December 1, 1997, pursuant to which Mr. Boyle owns 30,000
ordinary shares. Mr. Boyle is required to contribute to the capital of Saville
any shares that have not vested at the time that Mr. Boyle ceases to be a member
of Saville's Board of Directors. Mr. Boyle is prohibited from transferring any
of the shares for so long as they are not vested. ADC and Mr. Boyle have entered
into a Restricted Stock Rollover Agreement, pursuant to which the shares of ADC
common stock to be received in the Acquisition by Mr. Boyle upon cancellation of
the 30,000 ordinary shares subject to his Stock Restriction Agreement will be
subject to the same vesting and transfer restrictions as are contained in the
existing Stock Restriction Agreement after the Acquisition.


    INDEMNIFICATION OF DIRECTORS AND OFFICERS

    All rights to indemnification existing in favor of the present or former
directors and officers of Saville, as in effect on the date of the Acquisition
Agreement, with respect to matters occurring through the Effective Time, shall
survive the Acquisition and shall continue in full force and effect for a period
of six years from the Effective Time. In addition, pursuant to the Acquisition
Agreement, for not less than six years after the Effective Time, ADC has agreed
to maintain the current policies of directors' and officers' liability insurance
historically maintained by Saville and its subsidiaries with respect to matters
occurring

                                       45
<PAGE>
prior to the Effective Time; provided, that, (i) ADC may substitute policies
with substantially the same or better coverage containing terms and conditions
which are not less advantageous, in any material respect, to such parties and
(ii) ADC will not be required to pay an annual premium in excess of 200% of the
annual premium in effect immediately prior to the Effective Time.


    ADC BOARD SEATS.  Subsequent to the execution of the Acquisition Agreement
by ADC and Saville, ADC's board of directors has considered whether it would be
in the best interests of ADC and its shareholders to invite certain members of
Saville's board of directors to serve as members of ADC's board of directors
following the Acquisition. While no invitation has been extended to any of
Saville's board members as of the date of this Proxy Statement, invitations to
serve on ADC's board of directors may be made prior to the completion of the
Acquisition, with any appointment to be effective following consummation of the
Acquisition.


REGULATORY FILINGS AND APPROVALS


    In addition to the High Court proceedings described under "The Acquisition,"
the obligation of each party to fulfill its respective obligations under the
Acquisition Agreement is subject to obtaining the prior approval or consent of
the following governmental agencies:



    Under the Irish Control Act, the Acquisition may not be consummated until
notifications have been given and certain information has been furnished to the
Minister for Enterprise, Trade and Employment (the "Minister") and either the
Minister has stated in writing that he does not intend to make an order under
Section 6 of the Irish Control Act with respect to the Acquisition or the
relevant period within the meaning of Section 6 of the Irish Control Act has
elapsed. ADC and Saville filed the appropriate notification forms and
information with the Minister on July 23, 1999.



    Under the HSR Act and the rules promulgated thereunder by the United States
Federal Trade Commission (the "FTC"), the Acquisition may not be consummated
until notifications have been given and certain information has been furnished
to the FTC and the Antitrust Division of the Department of Justice (the
"Antitrust Division") and specified waiting period requirements have been
satisfied or approval granted. On July 15, 1999, the FTC granted ADC and Saville
early termination of the waiting period under the HSR Act.


    The Acquisition Agreement also provides that certain approvals must be
obtained from applicable Canadian and Australian antitrust authorities or
applicable waiting periods must have expired prior to consummation of the
Acquisition.

    At any time before or after consummation of the Acquisition, the antitrust
authorities described above could take such action under their respective
antitrust laws as they deem necessary or desirable in the public interest,
including seeking to enjoin the consummation of the Acquisition or seeking
divesture of assets of ADC or Saville. In addition, at any time after the
Effective Time of the Acquisition, any state could take such action under its
antitrust laws as it deems necessary or desirable in the public interest. Such
action could include seeking to enjoin the consummation of the Acquisition or
seeking divestiture of assets of ADC or Saville. Private parties may also seek
to take legal action under the antitrust laws under certain circumstances.

    Based on information available to them, ADC and Saville believe that the
Acquisition can be effected in compliance with Irish, United States federal and
state, Canadian and Australian antitrust laws. However, there can be no
assurance that a challenge to the consummation of the Acquisition on antitrust
grounds will not be made or that, if such a challenge were made, ADC and Saville
would prevail or would not be required to accept certain conditions, including
the divestiture of assets and/or commitments as to future business practices and
other matters in order to consummate the Acquisition.

                                       46
<PAGE>
ACCOUNTING TREATMENT

    ADC and Saville intend for the Acquisition to be treated as a pooling of
interests for accounting and financial reporting purposes. Under this method of
accounting, the recorded assets and liabilities of Saville will be carried
forward to ADC at their recorded amounts, income of ADC will include income or
loss of Saville for the entire fiscal year in which the combination occurs and
the reported income or loss of the separate companies for prior periods will be
combined and restated as income or loss of ADC. Saville received a letter from
PricewaterhouseCoopers LLP, its independent accountants, dated June 18, 1999,
stating that, based in part on analysis prepared by management, Saville will
qualify as a party to a pooling of interests transaction. ADC received a letter
from Arthur Andersen LLP, its independent accountants, dated June 18, 1999,
stating that, based in part on analysis prepared by management, ADC will qualify
as a party to a pooling of interests transaction. It is a condition to
consummation of the Acquisition that neither of these letters be withdrawn or
modified in any respect as of the Effective Date and that ADC shall have
received a letter from Arthur Andersen LLP, dated as of the Effective Date,
stating that, based in part on the letter of PricewaterhouseCoopers LLP and its
familiarity with ADC, the Acquisition will qualify as a pooling of interests
transaction under Accounting Principles Board Opinion No. 16 and applicable
regulations of the Commission. See "The Acquisition Agreement and the
Scheme--Conditions."


    To help ensure that Saville and ADC meet the prerequisites for pooling of
interests accounting treatment, the affiliates of Saville and the affiliates of
ADC will each execute a letter agreement to the effect that such person will not
sell, transfer or otherwise dispose of, or reduce such person's interest in or
risk relating to, any of Saville's ordinary shares or shares of ADC common stock
from the date that is 30 days prior to the Effective Time (or the termination of
the Acquisition Agreement), and thereafter will not sell any shares of ADC
common stock received in the transaction or otherwise beneficially owned by such
person until ADC publicly releases combined financial results which reflect 30
days of combined operations of ADC and Saville.


FEDERAL SECURITIES LAW CONSEQUENCES


    All shares of ADC common stock received by shareholders of Saville in the
Acquisition will be issued pursuant to an exemption from registration under
Section 3(a)(10) under the U.S. Securities Act of 1933, as amended (the
"Securities Act"), and will therefore be freely transferable, except that shares
of ADC common stock received by persons who are deemed to be affiliates of
Saville prior to the Acquisition may be resold by them in the U.S. only in
transactions permitted by the resale provisions of Rule 145 promulgated under
the Securities Act (or Rule 144 in the case of such persons who become
affiliates of ADC) or otherwise in compliance with (or pursuant to an exemption
from) the registration requirements of the Securities Act. Persons deemed to be
affiliates of Saville or ADC are those individuals or entities that control, are
controlled by, or are under common control with, such party and generally
include executive officers and directors of such party as well as certain
principal shareholders of such party. The Acquisition Agreement requires Saville
to use its best efforts to cause each of its affiliates to execute a written
agreement to the effect that such person will not offer or sell or otherwise
dispose of any of the shares of ADC common stock issued to such person in or
pursuant to the Acquisition except in compliance with the Securities Act and the
rules and regulations promulgated by the Commission thereunder.


STOCK MARKET QUOTATION

    It is a condition to the Acquisition that the shares of ADC common stock to
be issued pursuant to the Scheme be approved for quotation on the Nasdaq
National Market. An application will be filed for listing the shares of ADC
common stock to be issued in the Scheme on the Nasdaq National Market.

                                       47

NO RIGHT TO DISSENT


    If the shareholders of Saville approve the Scheme and the reduction of
Saville's capital in accordance therewith, and the High Court sanctions the
Scheme and confirms the reduction of Saville's capital, then, subject to the
Scheme becoming effective in accordance with its terms, each of Saville's
ordinary shares and deferred shares will be automatically deemed cancelled in
consideration for the right to receive that number of shares of ADC common stock
as determined by the Ordinary Share Allotment Ratio or the Deferred Share
Allotment Ratio, as the case may be, and each Saville option will be
automatically assumed and converted into an ADC option, and no holder of any of
the foregoing securities will have a right under Irish law to dissent or obtain
the "full value" of, or otherwise seek a court appraisal of the value of, such
securities.



SURRENDER OF SHARE CERTIFICATES AND ADRS



    Following the Effective Time, ADC will cause a letter of transmittal to be
mailed to all holders of ordinary shares (including those represented by ADSs
evidenced by ADRs) and deferred shares containing instructions for surrendering
their certificates representing ordinary shares and deferred shares and ADRs.
CERTIFICATES AND ADRS SHOULD NOT BE SURRENDERED UNTIL THE LETTER OF TRANSMITTAL
IS RECEIVED, FULLY COMPLETED AND RETURNED BY SUCH HOLDER AS INSTRUCTED IN THE
LETTER OF TRANSMITTAL.


CERTAIN TAX CONSIDERATIONS

    UNITED STATES FEDERAL INCOME TAX CONSEQUENCES


    The following discussion summarizes the U.S. federal income tax consequences
to U.S. Holders (as defined below) of (i) the receipt of shares of ADC common
stock in consideration for the cancellation of ordinary shares and deferred
shares and (ii) the assumption of Saville options and the conversion thereof
into ADC options, as described in the Acquisition Agreement. The discussion is
based on the Internal Revenue Code of 1986, as amended (the "Code"), Treasury
regulations, judicial decisions and published positions of the IRS, all as in
effect on the date hereof, and all of which are subject to change, possibly with
retroactive effect. This discussion does not address all aspects of U.S. federal
income taxation (including potential application of the alternative minimum tax)
that may be relevant to a particular shareholder or optionholder based on such
holder's particular circumstances and does not address any aspect of state,
local or non-U.S. tax laws. Further, with respect to the discussion of ordinary
shares and deferred shares, this summary generally considers only U.S. Holders
that hold their ordinary shares as capital assets (generally, assets held for
investment) and may not apply to all shareholders. In particular, the discussion
may not apply to shareholders (i) who acquired their ordinary shares pursuant to
the exercise of employee stock options or other compensation arrangements with
Saville; (ii) who are subject to special tax treatment under the Code (such as
broker-dealers, insurance companies, tax-exempt organizations, financial
institutions, and regulated investment companies); (iii) who hold the ordinary
shares as part of a "straddle," "hedge," or "conversion transaction," or to
holders whose functional currency is not the U.S. dollar; (iv) who own, or have
owned, directly, indirectly, or through attribution, currently or during the
past five years, 10% or more of the ordinary shares; or (v) who are certain
expatriates or former long-term residents of the U.S.


    For purposes of this discussion, a "U.S. Holder" is any holder of ordinary
shares or deferred shares of Saville who is (i) a citizen or resident of the
U.S.; (ii) a corporation or other entity taxable as a corporation organized
under the laws of the U.S. or of any state thereof or the District of Columbia;
(iii) an estate the income of which is included in gross income for U.S. federal
income tax purposes regardless of source; (iv) a trust, if a U.S. court is able
to exercise primary supervision over its administration and one or more U.S.
persons have the authority to control all of its substantial decisions; or (v)
any other person who is subject to U.S. federal income tax on a net income basis
with respect to the ordinary shares or deferred shares. In the case of a holder
of ordinary shares or deferred shares that is a partnership for U.S. federal

                                       48
<PAGE>
income tax purposes, each partner of such partnership will take into account its
allocable share of income or loss from the ordinary shares or deferred shares,
and will take such income or loss into account under the rules of taxation
applicable to such partner, taking into account the activities of the
partnership and the partner.

   ISSUANCE OF ADC COMMON STOCK IN CONSIDERATION FOR CANCELLATION OF ORDINARY
   SHARES AND DEFERRED SHARES

    Hale and Dorr LLP has acted as counsel to Saville in connection with the
Acquisition. In the opinion of Hale and Dorr LLP, as of the date hereof, the
Scheme will constitute a reorganization within the meaning of Section 368(a) of
the Code (a "Reorganization"). This opinion is based on factual representations
of Saville and ADC and which are customarily given in transactions of this type.

    Based on the conditions and assumptions referred to above, as a result of
the Scheme qualifying as a Reorganization, no gain or loss will be recognized by
U.S. Holders of ordinary shares or deferred shares solely as the result of the
cancellation of their ordinary shares or deferred shares in consideration for
shares of ADC common stock pursuant to the Scheme. The aggregate tax basis of
the shares of ADC common stock received pursuant to the Scheme will be the same
as the aggregate tax basis of the ordinary shares or deferred shares cancelled
in consideration therefor pursuant to the Scheme. The holding period of the
shares of ADC common stock received will include the holding period of the
ordinary shares or deferred shares cancelled in consideration therefor pursuant
to the Scheme.

    Neither Saville nor ADC has requested a ruling from the IRS with regard to
any of the U.S. federal income tax consequences of the Acquisition, and the IRS
is not precluded from successfully asserting that the cancellation of ordinary
shares or deferred shares pursuant to the Scheme is not a Reorganization,
contrary to the opinion of counsel.


    A successful IRS challenge to the Reorganization status of the Scheme would
result in a U.S. Holder of ordinary shares or deferred shares recognizing
taxable gain or loss with respect to each ordinary share or deferred share
cancelled equal to the difference between (i) the fair market value, as of the
time of the consummation of the Scheme, of the shares of ADC common stock
received and (ii) the U.S. Holder's basis in the ordinary shares or deferred
shares cancelled. In that event a U.S. Holder's basis in the shares of ADC
common stock received in the Scheme would equal its fair market value as of the
time of the consummation of the Scheme and the U.S. Holder's holding period for
that stock will begin on the day after the day of the consummation of the
Scheme.


    Provided the consummation of the Scheme qualifies as a Reorganization,
neither Saville nor ADC will recognize gain or loss as the result of the Scheme.

    CONVERSION OF SAVILLE OPTIONS TO ADC OPTIONS

    Saville believes that the assumption and conversion by ADC of Saville
options pursuant to the Acquisition will be treated as an exchange of such
Saville options for U.S. federal income tax purposes. In general, the receipt by
U.S. Holders of ADC options in exchange for outstanding Saville options, as
described in the Acquisition Agreement, will not be a taxable event to U.S.
Holders of Saville options for U.S. federal income tax purposes. The ADC options
received by U.S. Holders in substitution for Saville Options are "non-qualified
stock options" for U.S. federal tax purposes and will be treated as
non-qualified stock options.

    THE TAX DISCUSSION SET FORTH ABOVE IS INCLUDED FOR GENERAL INFORMATION ONLY.
DUE TO THE INDIVIDUAL NATURE OF TAX CONSEQUENCES, SHAREHOLDERS ARE URGED TO
CONSULT THEIR TAX ADVISORS AS TO THE SPECIFIC TAX CONSEQUENCES TO THEM OF THE
SCHEME, INCLUDING THE APPLICATION TO THEM OF ANY PENDING LEGISLATION, TAX
REPORTING REQUIREMENTS, THE ALTERNATIVE MINIMUM TAX AND THE EFFECTS OF
APPLICABLE STATE, LOCAL OR FOREIGN INCOME OR OTHER TAX LAWS.

    IRISH TAX CONSEQUENCES


    The following summary is general in character and is based on certain
aspects of current Irish law, regulations, rulings and decisions and Irish
Revenue practice, all of which are subject to change. Any such change may be
applied retroactively and may adversely affect the summary. This summary does
not address all possible tax consequences relating to the Scheme. Attention is
drawn to the fact that the summary is not comprehensive and that shareholders
and optionholders should consider their individual situation with their usual
tax adviser.


    ISSUANCE OF ADC COMMON STOCK IN CONSIDERATION FOR CANCELLATION OF ORDINARY
     SHARES AND DEFERRED SHARES


    The receipt of ADC common stock in consideration for the cancellation of
ordinary shares or deferred shares will not give rise to Irish capital gains
tax. Holders of ordinary shares or deferred shares will be treated as having
acquired the ADC common stock on the same date and for the same cost as the
ordinary shares or deferred shares.



    CONVERSION OF SAVILLE OPTIONS TO ADC OPTIONS



    The assumption of Saville options by ADC and their conversion into ADC
options is not a taxable event under Irish law.


    THE DISCUSSION SET FORTH ABOVE IS INCLUDED FOR GENERAL INFORMATION ONLY.
EACH SHAREHOLDER OF SAVILLE SHOULD CONSULT HIS OR HER OWN TAX ADVISOR WITH
RESPECT TO THE SPECIFIC TAX CONSEQUENCES OF THE ACQUISITION TO HIM OR HER.

                    THE ACQUISITION AGREEMENT AND THE SCHEME

    THE FOLLOWING IS A BRIEF SUMMARY OF CERTAIN ASPECTS OF THE ACQUISITION
AGREEMENT AND THE SCHEME. THIS SUMMARY DOES NOT PURPORT TO BE COMPLETE AND IS
QUALIFIED IN ITS ENTIRETY BY THE ACQUISITION AGREEMENT AND THE SCHEME, WHICH ARE
ATTACHED TO THIS PROXY STATEMENT AS ANNEX A AND ANNEX B, RESPECTIVELY. WE HAVE
NOT FILED WITH THE COMMISSION ALL EXHIBITS OR OTHER AGREEMENTS REFERRED TO IN
THE ACQUISITION AGREEMENT OR THE SCHEME. CAPITALIZED TERMS USED HEREIN AND NOT
OTHERWISE DEFINED HEREIN HAVE THE RESPECTIVE MEANINGS ASCRIBED TO SUCH TERMS IN
THE ACQUISITION AGREEMENT.

GENERAL


    The Scheme provides that, following approval by the shareholders of Saville
and the sanctioning of the Scheme by the High Court, all of the issued ordinary
shares and deferred shares of Saville will be cancelled and the holders thereof
will be allotted a number of shares of ADC common stock, as described herein.


CANCELLATION AND ALLOTMENT OF SHARES


    Upon sanction of the Scheme, the share capital of Saville will be reduced by
the cancellation of Saville's ordinary shares and deferred shares, and the
holders of the ordinary shares and deferred shares will be allotted shares of
ADC common stock. In consideration for the cancellation of the ordinary shares
and deferred shares, ADC will issue (i) 0.358 share of ADC common stock to the
holders of ordinary shares for each ordinary share outstanding at the Effective
Time and (ii) 0.027 share of ADC common stock to the holders of deferred shares
for each deferred share outstanding at the Effective Time. No fractional shares
of ADC common stock will be issued to any holder of ordinary shares or deferred
shares. Any fractional shares will be rounded up to the next whole share of ADC
common stock in the case of record holders of ordinary shares or deferred shares
and rounded down to the next whole share of ADC common stock in the case of ADRs
and Saville options being exchanged for ADC options.

recent financial statements of Saville included in Saville's SEC Reports or
incurred in the ordinary course of business consistent with past


                                       52
<PAGE>
practice; or (u) will not authorize, recommend, propose, agree or announce an
intention to do any of the foregoing or enter into any contract, agreement,
commitment or arrangement to do any of the foregoing.

NO SOLICITATION


    The Acquisition Agreement provides that Saville will (and will cause its
officers, directors, employees, investment bankers, attorneys and other agents
to) cease all discussions, negotiations, responses to inquiries and other
communications relating to any potential business combination with all third
parties who, prior to the date of the Acquisition Agreement, may have expressed
or otherwise indicated any interest in pursuing an acquisition with Saville.
Saville will not, nor shall it authorize or permit any officers, directors or
employees of, or any investment bankers, attorneys or other agents retained by
or acting on behalf of, Saville to (i) initiate, solicit or encourage, directly
or indirectly, any inquiries or the making of any proposal that constitutes an
Acquisition Proposal, (ii) engage or participate in negotiations or discussion
with, or furnish any information or data to, or take any other action to,
facilitate any inquiries or making any proposal by, any third party relating to
an Acquisition Proposal, or (iii) enter into any agreement with respect to any
Acquisition Proposal or approve an Acquisition Proposal. Prior to the Meetings,
Saville and its Board of Directors may participate in discussions or
negotiations with or furnish information to any third party making an
unsolicited acquisition proposal (a "Potential Acquiror") or approve or
recommend an unsolicited acquisition proposal if both (A) a majority of the
directors of Saville, without including directors who have a financial interest
in such Acquisition Proposal or who are or may be considered Affiliates (as
defined in Rule 405 under the Securities Act) or "connected persons" (as defined
in Section 26 of the Irish Companies Act, 1990), of any person making an
Acquisition Proposal ("disinterested directors") determines in good faith, after
receiving advice from its financial advisor, that a Potential Acquiror has
submitted to Saville an Acquisition Proposal that is a Superior Proposal, and
(B) a majority of the disinterested directors determines in good faith, after
receiving advice from reputable outside legal counsel experienced in such
matters, that the failure to participate in such discussions or negotiations or
to furnish such information is inconsistent with the directors' fiduciary duties
under applicable law.


    For purposes of the Acquisition Agreement, a "Superior Proposal" means any
BONA FIDE Acquisition Proposal to acquire (including by means of a scheme of
arrangement), directly or indirectly, for consideration consisting of cash
and/or securities, more than 50% of the ordinary shares then outstanding or all
or substantially all of the assets of Saville, and otherwise on terms that a
majority of the disinterested directors determines, in good faith, to be more
favorable to Saville and its shareholders than the Scheme, after receiving
advice from Morgan Stanley, Saville's independent financial advisor, and for
which financing, to the extent required, is then committed. In the event that
Saville receives any Acquisition Proposal, it must within 24 hours after receipt
of the Acquisition Proposal, furnish to ADC the identity of the recipient of the
information and of the Potential Acquiror, the terms of the Acquisition Proposal
and copies of all related information. If Saville delivers to ADC a written
notice of its intention to enter into an agreement with another acquiror to
effect the Acquisition Proposal, then ADC may propose amendments to the terms of
the Acquisition Agreement to be at least as favorable as the Acquisition
Proposal. If three days after the date notice of the Acquisition Proposal was
delivered to ADC by Saville, Saville believes that the Acquisition Proposal is a
Superior Proposal, then Saville may terminate the Acquisition Agreement and pay
the Termination Fee (described below).

RELATED MATTERS AFTER THE ACQUISITION


    At the Effective Time, Saville will become a wholly owned subsidiary of ADC.
ADC will own 100% of the issued and outstanding share capital of Saville. After
the Effective Time, all ordinary shares represented by ADSs and evidenced by
ADRs will cease to be listed on the Nasdaq National Market, and ADC will
terminate the registration of Saville under the U.S. Securities Exchange Act of
1934, as amended.


                                       53
<PAGE>
STOCK OPTIONS AND EMPLOYEE BENEFITS

    At the Effective Time, pursuant to the terms of Saville's 1995 Share Option
Plan and the agreements representing the Saville options and with no further
action by or on behalf of the holders of the Saville options, each option to
purchase Saville ordinary shares issued by Saville pursuant to the 1995 Share
Option Plan or otherwise, outstanding and unexercised, whether or not vested or
exercisable, shall be assumed by ADC. Each Saville option will become an option
to acquire, on the same terms and conditions as were applicable under the
Saville option (after giving effect to the accelerated vesting provisions
contained in the applicable agreements or the Share Option Plan), the number of
whole shares of ADC common stock equal to the number of Saville ordinary shares
that were issuable upon exercise of such Saville option immediately prior to the
Effective Time multiplied by the Ordinary Share Allotment Ratio, rounded down to
the nearest whole number of shares of ADC common stock, and the per share
exercise price of the shares of ADC common stock issuable upon exercise of such
ADC option shall be equal to the exercise price per share of Saville ordinary
shares at which such Saville option was exercisable immediately prior to the
Effective Time divided by the Ordinary Share Allotment Ratio, rounded up to the
nearest whole cent. ADC has agreed to cause the ADC common stock issuable upon
exercise of the ADC options to be listed on the Nasdaq National Market. On or
immediately following the Effective Time, ADC will file a registration statement
with the Commission on Form S-8 with respect to the ADC common stock underlying
such ADC options.

    ADC has agreed in the Acquisition Agreement to provide, during the period
commencing at the Effective Time and ending on the first anniversary thereof, to
the employees of Saville and its Subsidiaries who become employees of ADC as of
the Effective Time a package of benefits under employee benefit plans that are
not materially less favorable, in the aggregate, to those employees than the
benefits currently provided, in the aggregate, by Saville and its Subsidiaries
to those employees (excluding any benefits under Saville's Employee Stock
Purchase Plan).

INDEMNIFICATION

    The Acquisition Agreement provides that, as of the date of the Acquisition
Agreement and for a period of six years thereafter, ADC will indemnify and hold
harmless from and against all claims, damages, losses, obligations or
liabilities ("Losses") any persons who were directors or officers of Saville,
prior to the Effective Time to the fullest extent such person could have been
indemnified for such Losses under applicable law or under the governing
documents of Saville in effect immediately prior to the date of the Acquisition
Agreement, with respect to any act or failure to act by any such indemnified
person prior to the Effective Time. ADC shall maintain in effect for not less
than six years from the Effective Time the current policies of directors' and
officers' liability insurance maintained by Saville with respect to all matters,
including the transactions contemplated by the Acquisition Agreement, occurring
prior to, and including the Effective Time; provided that, in the event that any
Claim is asserted or made within such six-year period, such insurance will be
continued in respect of any such Claim until final disposition of any and all
such Claims; and provided, further, that ADC will not be obligated to make
annual premium payments for such insurance to the extent such premiums exceed
200% of the premiums paid as of the date of the Acquisition Agreement by Saville
or any Subsidiary for such insurance. In such case, ADC will purchase as much
coverage as possible for 200% of the premiums paid as of the date of the
Acquisition Agreement for such insurance, which coverage will be at least as
favorable as that provided by ADC to its directors.

CONDITIONS

    The respective obligations of ADC and Saville to effect the Acquisition is
subject to the satisfaction or waiver on or prior to the Effective Date of the
following conditions: (a) requisite shareholder approvals shall have been
obtained on the matters proposed at the Meetings; (b) no judgment, order,
decree, statute, law, ordinance, rule or regulation entered, enacted,
promulgated, enforced or issued by any court or other

                                       54
<PAGE>
governmental entity or competent jurisdiction or other legal restraint or
prohibition shall be in effect (i) imposing or seeking to impose material
limitations on the ability of ADC to acquire or hold or to exercise full rights
of ownership of any ordinary shares of Saville; (ii) imposing or seeking to
impose material limitations on the ability of ADC and its affiliates to combine
and operate the business and assets of Saville; (iii) imposing or seeking to
impose other material sanctions, damages, or liabilities directly arising out of
the Acquisition on ADC or Saville; (iv) requiring or seeking to require
divestiture by ADC of all or any material portion of the business, assets or
property of Saville; or (v) preventing the consummation of the Acquisition; (c)
no action or proceeding shall be instituted by any governmental entity seeking
to prevent consummation of the Acquisition, asserting the illegality of the
Acquisition or the Acquisition Agreement or seeking material damages directly
arising out of the transactions contemplated thereby which continues to be
outstanding; (d) all necessary authorizations, consents, orders or approvals of,
or declarations or filings with, or expiration or waiver of waiting periods
imposed by, any governmental entity of any applicable jurisdiction required for
the consummation of the transactions contemplated by the Acquisition Agreement
shall have been filed, expired or obtained which the failure to obtain, make or
occur would have the effect of making the Scheme or the Acquisition Agreement or
any of the transactions contemplated thereby illegal or which individually or in
the aggregate would have a material adverse effect on ADC.

    In addition, the obligation of ADC to effect the Acquisition is further
subject to satisfaction or waiver of the following conditions: (a) the
representations and warranties of Saville shall be true and correct both when
made and at and as of the Effective Date, as if made at and as of such time,
except where the failure of such representations and warranties to be so true
and correct does not have, and would not, individually or in the aggregate,
reasonably be expected to have a material adverse effect on Saville; (b) Saville
shall have performed in all material respects all obligations required to be
performed by it under the Acquisition Agreement at or prior to the Effective
Time; (c) since the date of the Acquisition Agreement, there shall not have been
a material adverse effect on Saville, nor any change, event or condition that,
with the passage of time, would reasonably be expected to result in a material
adverse effect on Saville; (d) Saville shall have delivered to ADC a certificate
of the President and Chief Financial Officer of Saville, and a copy of the
Memorandum of Association of Saville certified by the Secretary of Saville; (e)
ADC shall have received the resignations of certain directors and officers of
Saville; (f) Saville and ADC shall have received certain letters from
PricewaterhouseCoopers LLP and Arthur Andersen LLP, respectively, with respect
to the accounting treatment of the Acquisition as a pooling of interests; (g)
ADC shall have received certain letters by certain affiliates of Saville; (h)
any outstanding minority ownership interest in Saville's subsidiaries shall be
transferred to Saville, for no consideration; and (i) Saville's Executive

satisfaction or waiver of the following conditions: (a) the representations and
warranties of ADC shall be true and correct both when made and at and as of the
Effective Date, as if made at and as of such time, except where the failure of
such representations and warranties to be so true and correct does not have, and
would not, individually or in the aggregate, reasonably be expected to have a
material adverse effect on ADC; (b) ADC shall have performed in all material
respects all its obligations required to be performed by it under the
Acquisition Agreement; (c) ADC shall have delivered to Saville a certificate of
the President and the Chief Financial Officer of ADC; and (d) Saville shall have

Acquisition will be treated for U.S. federal income tax purposes as a
reorganization within the meaning of Section 368(a) of the Code (but if Hale and
Dorr LLP does not provide the opinion, Dorsey & Whitney LLP may do so).

                            SAVILLE OPTION AGREEMENT

    THE FOLLOWING IS A BRIEF SUMMARY OF CERTAIN ASPECTS OF THE OPTION AGREEMENT.
THIS SUMMARY DOES NOT PURPORT TO BE COMPLETE AND IS QUALIFIED IN ITS ENTIRETY BY
THE OPTION AGREEMENT, WHICH IS INCORPORATED IN THIS PROXY STATEMENT BY
REFERENCE. THE OPTION AGREEMENT IS ATTACHED TO THIS PROXY STATEMENT AS ANNEX D.


    Pursuant to the Option Agreement, ADC has the right (the "Option"), under
the circumstances described below, to acquire up to 7,799,805 of the authorized
but unissued ordinary shares of Saville (the "Option Shares") (or approximately
19.9% of the outstanding ordinary shares as of June 19, 1999), at a per share
exercise price of $17.50 (the "Option Price"), payable in cash. The Option
Agreement could have the effect of making an acquisition of Saville by a third
party more costly because of the need to acquire in any such transaction the
Option Shares issued under the Option Agreement, and could also jeopardize the
ability of a third party to acquire Saville in a transaction to be accounted for
as a pooling of interests.


    The Option may be exercised by ADC, in whole or in part, at any time or from
time to time after the occurrence of an event that would entitle ADC, upon
termination of the Acquisition Agreement, to payment of the Termination Fee (as
described in "The Acquisition Agreement and the Scheme-- Termination;
Termination Fees and Expenses") and in certain other circumstances in which a
third party acquires, commences a tender offer for, announces the acquisition of
or receives an option to acquire more than 20% of the outstanding ordinary
shares of Saville. In lieu of the payment of the Option Price and the receipt of
the Option Shares, under certain circumstances, ADC may require Saville to
repurchase the Option (the "Put") at a cash purchase price equal to the product
determined by multiplying (A) the number of Option Shares as to which the Option
has not yet been exercised by (B) the excess of (i) the fair market value of the
ordinary shares (as determined in accordance with the terms of the Option
Agreement) over (ii) the Option Price.

    The Option Agreement further provides that if ADC desires to sell any of the
Option Shares and such sale requires the registration of such shares under the
Securities Act, Saville will be required to prepare and file (subject to certain
limitations) a registration statement under the Securities Act for the purpose
of permitting such sale of shares by ADC.

    Notwithstanding any other provision of the Option Agreement, in no event
shall ADC's Total Profit (as defined below) exceed $21,000,000 and, if it
otherwise would exceed such amount, ADC, at its sole election, shall either (i)
deliver to Saville for cancellation Option Shares previously acquired by ADC,
(ii) pay cash or other consideration to Saville or (iii) undertake any
combination thereof, in each case, so that ADC's Total Profit does not exceed
$21,000,000. "Total Profit" means the sum (before taxes) of the following: (A)
the amount of cash received by ADC pursuant to the Put, (B)(1) the net cash
amounts received by ADC pursuant to the sale of Option Shares (or any other
securities into which such Option Shares are converted or exchanged) to any
unaffiliated party, less (2) the aggregated Option Price paid for all Option
Shares acquired by ADC and (C) any Termination Fee received pursuant to the
Acquisition Agreement.

    The Option shall terminate upon the earlier of (i) the Effective Time and
(ii) the termination of the Acquisition Agreement (unless the Acquisition
Agreement is terminated under circumstances requiring Saville to pay ADC the
Termination Fee and such Termination Fee has not been paid).

                        DESCRIPTION OF ADC CAPITAL STOCK

GENERAL

    The rights of the shareholders of ADC are governed by the Minnesota Business
Corporation Act (the "MBCA"), the Restated Articles of Incorporation of ADC, as
amended (the "ADC Articles"), and the Composite Restated Bylaws of ADC, as
amended (the "ADC Bylaws"). The following does not purport to be a complete
statement of the rights of ADC shareholders under applicable Minnesota law and
the ADC Articles and ADC Bylaws.


    The ADC Articles authorize ADC to issue up to 310,000,000 shares, divided
into 300,000,000 shares of ADC common stock, and 10,000,000 shares of Preferred
Stock, no par value (the "ADC Preferred Stock"). As of June 18, 1999, there were
135,636,594 shares of ADC common stock outstanding and no shares of ADC
Preferred Stock were outstanding. Shares of ADC Preferred Stock may be issued
from time to time in one or more series, and before any shares of any such
series of ADC Preferred Stock are issued, the Board of Directors of ADC shall
fix and determine the designations, powers, preferences and relative
participating, optional and other special rights, and the qualifications,
limitations and restrictions thereof. Although ADC's Board of Directors has no
current plans for any issuance of ADC Preferred Stock, such ADC Preferred Stock
could have dividend, liquidation, voting and other rights superior to those of
ADC common stock.


SHAREHOLDER RIGHTS PLAN


    ADC has adopted a Shareholder Rights Plan (the "Shareholder Rights Plan")
under which the Board of Directors declared a dividend of one right (each, a
"Right") for each outstanding share of ADC common stock. The Shareholder Rights
Plan provides, among other things, that if any person or group acquires 15% or
more of ADC common stock, each Right not owned by such person or group will
entitle its holder to purchase, at the Right's then-current purchase price
(U.S.$62.50 for each one-half share of ADC common stock at October 31, 1998),
ADC common stock having a value equal to twice the Right's purchase price. The
Rights will not be triggered, however, if the acquisition of 15% or more of ADC
common stock is pursuant to a tender offer or exchange offer for all outstanding
shares of ADC common stock which is determined by the independent directors of
ADC to be fair and in the best interests of ADC and its shareholders. The Rights
are redeemable at U.S.$0.01 per Right at any time prior to the time they become
exercisable. The Rights will expire on November 28, 2005, if not previously
redeemed or exercised.

<PAGE>
                        COMPARISON OF SHAREHOLDER RIGHTS

SHAREHOLDER MEETINGS

    Under the MBCA and the ADC Bylaws, holders of ADC common stock are entitled
to at least 10 days' prior written notice for each regular meeting and special
meeting to consider any matter, except that the ADC Bylaws require that notice
of a meeting at which an agreement of merger or exchange is to be considered
shall be mailed to shareholders of record, whether entitled to vote or not, at
least 14 days prior to such meeting.

    Under Irish law and the articles of association of Saville (the "Saville
articles"), holders of ordinary shares are entitled to 21 days' prior written
notice of an annual general meting and of an extraordinary general meeting at
which a special resolution is to be proposed and to 14 days' prior written
notice of an extraordinary general meeting at which only ordinary resolutions
are to be proposed. A "special resolution", in order to be passed, requires the
approval of at least 75% of the votes cast at the relevant meeting and is
necessary for such proposals as changing the name of the company, altering its
objects (purposes clause) or articles of association or reducing its issued
share capital. An "ordinary resolution", in order to be passed, requires the
approval of a majority of the votes cast and is necessary for all proposals that
do not require a special resolution.

PROXIES

    Under the MBCA, a proxy is invalid after 11 months from its date, unless the
proxy provides for a longer period.

    Neither Irish law nor the Saville articles specify a period of time beyond
which an appointment of a proxy will not be valid.

RIGHT TO CALL SPECIAL MEETINGS

    Under the MBCA, a special meeting of shareholders may be called by the Chief
Executive Officer, the Chief Financial Officer, any two or more directors, a
person authorized in the articles or bylaws to call special meetings, or a
shareholder or shareholders holding 10% or more of all shares entitled to vote,
except that a special meeting called for the purpose of considering any action
to directly or indirectly facilitate or effect a business combination, including
any action to change or otherwise affect the composition of the board of
directors for that purpose, must be called by 25% or more of the voting power of
all shares entitled to vote. Under the ADC Bylaws, a special meeting may be
called by the Chairman of the Board, the President, the Treasurer, any two
directors or a shareholder or shareholders holding 10% or more of the voting
power of all shares entitled to vote, except that a special meeting called for
the purpose of considering any action to directly or indirectly facilitate or
effect a business combination, including any action to change or otherwise
affect the composition of the Board of Directors for that purpose must be called
by a shareholder or shareholders holding 25% or more of the voting power of all
shares entitled to vote.

    Under the Saville articles, the Board of Directors may call extraordinary
general meetings. Such a meeting may also be called by shareholders holding not
less than 10% of the paid up capital of the company carrying voting rights at
general meetings.

SHAREHOLDERS' DISSENTERS' RIGHTS

    Under the MBCA, shareholders may exercise a right of dissent from certain
actions of the corporation and obtain payment for the fair value of their
shares. This remedy is an exclusive remedy, except where the corporate action is
fraudulent with regard to the complaining shareholder.

                                       64
<PAGE>
    Under the MBCA, shareholders of a Minnesota corporation may exercise
dissenters' rights in connection with (i) an amendment of the articles of
incorporation that materially and adversely affects the rights or preferences of
the shares held by the dissenting shareholder, (ii) a disposition of all or
substantially all of the corporation's property and assets not in the usual
course of business, (iii) a plan of merger in which the shareholders may vote,
(iv) a plan of exchange involving the acquisition of the corporation's shares,
if the shareholder is entitled to vote on the plan and (v) any other corporate
action taken pursuant to a shareholder vote with respect to which the articles,
bylaws or a resolution approved by the board of directors directs that
dissenting shareholders may obtain payment for their shares. Shareholders of a
Minnesota corporation do not have the right to dissent if a vote of the
shareholders of the corporation is not necessary to authorize the merger or
other corporate action.

    Irish law does not generally provide for dissenters' rights (but see Mergers
and Consolidations below).

BOARD OF DIRECTORS

    The MBCA provides that the board of directors of a Minnesota corporation
shall consist of one or more directors as fixed by the articles of incorporation
or bylaws. The ADC Board currently consists of 11 directors (including two
vacant seats). The ADC Articles provide that the Board is divided into three
classes. The number of directors may be increased or decreased from time to time
by resolution adopted by the affirmative vote of the shareholders holding 80% of
the outstanding shares of capital stock entitled to vote generally in the
election of directors (the "Voting Stock"), unless the proposed increased or
decrease has been expressly approved by a majority vote of all members of the
Board of Directors, in which case such an increase or decrease shall require the
affirmative vote of the shareholders holding a majority of the outstanding
shares of Voting Stock.

    The MBCA provides that, unless modified by the articles or bylaws of the
corporation or by shareholder agreement, the directors may be removed with or
without cause by the affirmative vote of that proportion or number of the voting
power of the shares of the classes or series the director represents which would
be sufficient to elect such director (with an exception for corporations with
cumulative voting). The ADC Articles require the affirmative vote of the
shareholders holding 80% of the Voting Stock to remove a director, unless the
removal has been expressly approved by the majority vote of all members of the
Board of Directors, in which case the removal shall require the affirmative vote
of the shareholders holding a majority of the outstanding shares of Voting
Stock. Shareholders of ADC do not have the right to cumulative voting in the
election of directors.

    Under Irish law, a company must have at least two directors. Under the
Saville articles, the number of directors must not be less than two or more than
12. Saville's Board of Directors currently consists of 10 directors. Under the
Saville articles, the Board of Directors is divided into three classes. The
number of directors may be increased from time to time by an ordinary resolution
or by a majority vote of the Board.

    Under Irish law, shareholders have the right, irrespective of the provisions
of the articles of association, to remove a director by ordinary resolution,
provided that notice of the intention to propose the resolution has been given
to the company not less than 28 days before the relevant meeting.

    Shareholders of Saville do not have the right to cumulative voting in the
election of directors.

AMENDMENTS TO BYLAWS AND ARTICLES

    The MBCA and the ADC Bylaws provide that the power to adopt, amend or repeal
the bylaws is vested in the board (subject to certain notice requirements set
forth in the ADC Bylaws). The MBCA provides that the authority in the board of
directors is subject to the power of the shareholders to change or repeal such
bylaws by a majority vote of the shareholders at a meeting of the shareholders
called for such purpose, and the board of directors shall not make or alter any
bylaws fixing a quorum for meetings of shareholders, prescribing procedures for
removing directors or filling vacancies in the board of directors,

                                       65
<PAGE>
or fixing the number of directors or their classifications, qualifications or
terms of office. Under the MBCA, a shareholder or shareholders holding 3% or
more of the voting shares entitled to vote may propose a resolution to amend or
repeal bylaws adopted, amended or repealed by the board, in which event such
resolutions must be approved pursuant to the procedures for amending the
articles of incorporation.

    The MBCA provides that a proposal to amend the articles of incorporation may
be presented to the shareholders of a Minnesota corporation by a resolution (i)
approved by the affirmative vote of a majority of the directors present or (ii)
proposed by a shareholder or shareholders holding 3% or more of the voting
shares entitled to vote thereon. Under the MBCA, any such amendment must be
approved by the affirmative vote of a majority of the shareholders entitled to
vote thereon, except that the articles may provide for a specified proportion or
number larger than a majority. The ADC Articles provide that the affirmative
vote of the holders of at least 80% of the shares of Voting Stock is required in
order to amend provisions of the ADC Articles concerning the election and
removal of directors (unless the proposed change has been expressly approved by
a majority of all members of the ADC Board of Directors, in which case such
change shall be approved by a majority of the shares of Voting Stock), and that
the affirmative vote of the holders of 80% of the outstanding shares of Voting
Stock is required in order to amend provisions concerning certain mergers,
consolidations and other business combinations and reorganizations.


    Under Irish law, shareholders have the authority to alter most provisions of
a company's memorandum and all provisions of its articles of association by a
special resolution subject, in the case of certain amendments to the memorandum
of association, to the right of dissenting shareholders to apply to the courts
to cancel the amendments. Under Irish law the board of directors is not
authorized to change the memorandum or the articles of association. Amendments
affecting the rights of the holders of any class of shares may, depending on the
rights attached to such class and the nature of the amendments, also require
approval of the class affected at a separate class meeting, although an
amendment so approved will be subject to confirmation by the court if the
holders of at least 10% of the shares of that class apply to the court for the
cancellation of the amendment.


INDEMNIFICATION

    The MBCA provides that, unless prohibited or limited by a corporation's
articles or bylaws, a corporation shall indemnify its directors, officers and
employees made or threatened to be made a party to a proceeding because of such
person's acting as a director, officer or employee if the person (a) has not
been indemnified by another organization or employee benefit plan, (b) acted in
good faith, (c) received no improper personal benefit and the MBCA statute
concerning director conflicts of interest has been satisfied, if applicable, (d)
in the case of a criminal proceeding, had no reasonable cause to believe the
conduct was unlawful and (e) either reasonably believed that the conduct was in
the best interests of the corporation, or with respect to a director, officer or
employee of the corporation who was serving at the request of the corporation as
a director, officer, partner, trustee, employee or agent of another organization
or employee benefit plan or whose duties in that positions involved service as a
director, officer, partner, trustee, employee or agent of another organization
or employee benefit plan, reasonably believed that the conduct was not opposed
to the best interests of the corporation. The ADC Bylaws expressly adopt the
indemnification provisions of the MBCA. In addition, the MBCA requires the
corporation to report the indemnification payments to its shareholders not later
than the next meeting of shareholders.

    Irish law does not permit a company to indemnify a director or an officer of
the company or any person employed by the company as auditor against any
liability of such person by virtue of any rule of law in respect of his
negligence, default, breach of duty or breach of trust in relation to the
company except any liability incurred by such person in defending any legal
proceedings (whether civil or criminal) in which judgment is given in his favor
or in which he is acquitted or in certain proceedings brought by him in which,
although he is liable, a court finds that he acted honestly and reasonably and
that having regard to all the

                                       66
<PAGE>
circumstances he ought fairly to be excused and relief is granted by the court.
The Saville articles contain such an indemnity in respect of such persons.

LIABILITIES OF DIRECTORS

    Under the MBCA, a director may be liable to the corporation for
distributions made in violation of the MBCA or a restriction contained in the
corporation's articles or bylaws.

    The ADC Articles provide that a director shall not be personally liable to
ADC or its shareholders for monetary liability relating to breach of fiduciary
duty as a director, unless the liability relates to (i) a breach of the
director's duty of loyalty to the corporation or its shareholders, (ii) acts or
omissions involving a lack of good faith or which involve intentional misconduct
or a knowing violation of law, (iii) liability for illegal distributions and
unlawful sales of ADC securities, (iv) transactions where the director gained an
improper personal benefit, or (v) any acts or omissions occurring prior to the
date on which the liability limitation provisions of the ADC Articles became
effective. The ADC Articles provide that any repeal or modification of the
foregoing provisions shall not adversely affect any right or protection of a
director of ADC existing at the time of such repeal or modification.

    Irish law does not permit a company to exempt any director from any
liability which by virtue of any rule of law would otherwise attach to him in
respect of any negligence, default, breach of duty or breach of trust of which
he may be guilty in relation to the company.

MERGERS AND CONSOLIDATIONS

    The MBCA provides that a resolution containing a plan of merger or exchange
must be approved by the affirmative vote of a majority of the directors present
at a meeting of the board and must then be submitted to the shareholders of each
merging corporation (with certain statutory exceptions) and approved by the
affirmative vote of the holders of a majority of the voting power of all shares
entitled to vote. The MBCA requires that a class of shares of a corporation must
approve the plan if any provisions of the plan would, if contained in a proposed
amendment to the corporation's articles of incorporation, entitle such class to
vote as a class.


    Irish law provides for schemes of arrangement, which are arrangements or
compromises between a company and any class of its shareholders (or any class of
its creditors) and are used for certain types of reconstructions, amalgamations,
capital reorganizations or takeovers. They require the approval at a specially
convened meeting of a majority of the shareholders in number representing 75% in
value of the relevant class of shares present and voting, either in person or by
proxy, and the sanction of the court. Once so approved and sanctioned, all
shareholders of the relevant class are bound by the terms of the scheme; a
dissenting shareholder would have no dissenters' rights.


    Under another procedure, one public limited company may acquire all of the
assets and liabilities of another public limited company in exchange for the
issue of shares to the shareholders in the acquired company which will
subsequently be dissolved. This procedure requires the approval of a special
resolution of each company and the sanction of the court. In this case a
shareholder in either company who votes against the relevant special resolution
will have dissenters' rights and may require the acquiring company to acquire
his shares for cash.

    Acquisitions of companies in Ireland are commonly effected by way of a
tender offer. Irish law provides that where a take-over offer is made for the
shares of a certain class of a company incorporated in Ireland and, within four
months of the date of the offer, the offeror has, by virtue of acceptances of
the offer, acquired or contracted to acquire not less than 80% in value of the
shares to which the offer relates, the offeror may before the expiration of six
months after the date of the offer by notice compulsorily require shareholders
of the relevant class who do not accept the offer to transfer their shares on
the terms of the offer. A dissatisfied shareholder may apply to the court within
one month of the date on which such

                                       67
<PAGE>
notice was given objecting to the compulsory transfer or its terms. The court is
unlikely (in the absence of fraud or oppression) to exercise its discretion to
order that the compulsory transfer not take effect, but it may vary the terms of
the transfer if it thinks fit.

BUSINESS COMBINATIONS AND CONTROL SHARE ACQUISITIONS

    The MBCA prohibits certain business combinations (as defined in the MBCA)
between a Minnesota corporation with at least 100 shareholders, or a publicly
held corporation that has at least 50 shareholders, and an "interested
shareholder" for a four-year period following the share acquisition date by the
interested shareholder, unless certain conditions are satisfied or an exemption
is found. An "interested shareholder" is generally defined to include a person
who beneficially owns at least 10% of the votes that all shareholders would be
entitled to cast in an election of directors of the corporation. The MCBA also
limits the ability of a shareholder who acquires beneficial ownership of more
than certain thresholds of the percentage voting power of a Minnesota
corporation (starting at 20%) from voting those shares in excess of the
threshold unless such acquisition has been approved by a majority of the voting
power held by shareholders unaffiliated with such shareholder.

    The ADC Articles require the affirmative vote of at least 80% of the
outstanding shares of ADC Voting Stock in order to effect certain business
combinations, including a merger, consolidation, exchange of shares, sale of all
or substantially all of the assets of ADC or other similar transactions (a
"Business Combination"), with a person who, together with its affiliates, owns
15% or more of the outstanding Voting Stock of ADC (a "Related Person").
However, the 80% voting requirement will not be applicable if a majority of the
continuing directors approve the Business Combination and the cash or fair
market value of the property, securities or other consideration to be received
per share by holders of ADC common stock other than the Related Person is not
less than the highest per share price paid by the Related Person in acquiring
any of its holdings of ADC common stock.

    Neither Irish law nor the Saville articles contain provisions analogous to
those above.

OTHER ANTI-TAKEOVER PROVISIONS

    The MBCA provides that during any tender offer, a publicly held corporation
may not enter into or amend an agreement (whether or not subject to
contingencies) that increases the current or future compensation of any officer
or director. In addition, under the MBCA, a publicly held corporation is
prohibited from purchasing any voting shares owned for less than two years from
a 5% shareholder for more than the market value unless the transaction has been
approved by the affirmative vote of the holders of a majority of the voting
power of all shares entitled to vote or unless the corporation makes a
comparable offer to all holders of shares of the class or series of stock held
by the 5% shareholder and to all holders of any class or series into which such
securities may be converted.

    It should be noted that in addition to the anti-takeover measures discussed
above, the provisions of the ADC Articles and Bylaws (i) providing for a
staggered board of directors (discussed above), (ii) requiring a vote of 80% of
the outstanding Voting Stock to amend certain provisions of the ADC Articles
concerning the election and removal of directors and concerning certain Business
Combinations (discussed above under "Amendments to Articles" and "Business
Combinations"), (iii) limiting the right of shareholders to call a special
meeting of shareholders involving a business combination, or any change in the
composition of the board of directors as a result of such business combination,
to require the request of holders of at least 25% of the outstanding shares
(discussed above), and (iv) providing for certain shareholder rights in the
event that any person or group acquires 15% or more of ADC's common stock
(discussed above under "Shareholder Rights Plan") may make it more difficult to
effect a change in control of ADC and may discourage or deter a third party from
attempting a takeover.

    The rules (the "Irish Takeover Rules") made by the Irish Takeover Panel
pursuant to the Irish Takeover Panel Act, 1997, prohibit an Irish company which
is listed on the Irish Stock Exchange and is the

                                       68
<PAGE>
subject of a takeover offer from issuing shares or options over shares, making
material acquisitions or disposals, entering into contracts otherwise than in
the ordinary course of business or otherwise taking any action likely to
frustrate the making or implementation of the offer, except with the consent of
the Panel or the approval of the company's shareholders in general meeting.

    At a time when an Irish company is not subject to a takeover and is
therefore not subject to the Irish Takeover Rules, the fiduciary duties of the
directors (particularly the duty to exercise their powers only for their
intended purpose) may render it difficult for the directors to introduce
anti-takeover arrangements without shareholder approval.

           CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

    Certain information contained or incorporated by reference in this Proxy
Statement as to the future financial or operating performance of Saville both
before and after the acquisition by ADC, and of ADC, may constitute
"forward-looking statements." The Private Securities Litigation Reform Act of
1995 provides certain "safe harbor" protections for forward-looking statements
in order to encourage companies to provide prospective information about their
businesses. Forward-looking statements include statements concerning plans,
objectives, goals, strategies, future events or performance, and underlying
assumptions and other statements which are other than statements of historical
facts.

    ADC and Saville desire to take advantage of the "safe harbor" provisions of
the Private Securities Litigation Reform Act of 1995 and are including this
cautionary statement in connection with such safe harbor legislation. This Proxy
Statement, any Form 10-K, Form 10-Q, Current Report on Form 8-K filed by ADC or
Saville, as applicable, with the Commission or any other written or oral
statements made by or on behalf of ADC or Saville may include forward-looking
statements which reflect ADC's or Saville's current views with respect to future
events and financial performance. The words "believe," "expect," "anticipate,"
"intends," "estimate," "forecast," "project" and similar expressions identify
forward-looking statements.

    The forward-looking statements set forth or incorporated by reference in
this Proxy Statement are based upon various assumptions, many of which are
based, in turn, upon further assumptions, including without limitation,
management's examination of historical operating trends, data contained in
Saville's or ADC's records and other data available from third parties. Although
ADC and Saville believe that such assumptions were reasonable when made, because
such assumptions are inherently subject to significant uncertainties and
contingencies which are difficult or impossible to predict and are beyond
Saville's and ADC's control, there can be no assurance, and no representation or
warranty is made, that the expectations, beliefs or projections will result or
be achieved or accomplished. In addition to the other important factors and
matters discussed elsewhere herein and in the documents incorporated by
reference herein, important factors that, in the view of Saville, could cause
actual results to different materially from those discussed in the
forward-looking statements include completion of the transactions describe
herein, the achievement of the anticipated levels of profitability, growth, cost
and synergy, the timely development and acceptance of new products, the impact
of competitive pricing, the ability to obtain necessary regulatory approvals,
the impact of general business and global economic conditions and other
important factors described from time to time in the reports filed with the
Commission by Saville and ADC, including the factors described under the caption
"Certain Factors That May Affect Future Operating Results" in Saville's
Quarterly Report on Form 10-Q for the quarter ended March 31, 1999 and in
Exhibit 99-A to ADC's Quarterly Report on Form 10-Q for the fiscal quarter ended
April 30, 1999.

    None of ADC, Saville nor any of their respective agents, employees or
advisors intend or have any duty or obligation to supplement, amend, update or
revise any of the forward-looking statements contained or incorporated by
reference in this Proxy Statement.

(iii) the Company Options (as defined in Section 1.1(c) hereof) shall be assumed
by Buyer and converted into options for the purchase of shares of Buyer Common
Stock upon the terms and subject to the conditions set forth herein and in
Exhibit A, and, with respect to the Scheme, in accordance with the laws of
Ireland; and

    WHEREAS, for United States federal income tax purposes, the parties intend
that the Scheme and the other transactions described in the preceding Recital
(collectively, the "Acquisition") shall qualify as a "reorganization" under
Section 368(a) of the Internal Revenue Code of 1986, as amended (the "CODE"),
and that this Agreement constitute a "plan of reorganization" within the meaning
of the Code; and

    WHEREAS, for financial reporting purposes, the parties intend that the
Acquisition shall be accounted for as a "pooling of interests." The Company has
provided to Buyer an opinion letter from its independent accountants,
PricewaterhouseCoopers LLP, addressed to the Company, stating that, after
appropriate review of this Agreement and based on its familiarity with the
Company, the Company will qualify as a party to a pooling-of-interests
transaction under Opinion 16 of the Accounting Principles Board and applicable
SEC rules and regulations (collectively, "OPINION 16"). Buyer has provided to
the Company an opinion letter from its independent accountants, Arthur Andersen
LLP, addressed to Buyer, stating that, as of the date of such letter, based on
its familiarity with Buyer, Buyer will qualify as a party to a
pooling-of-interests transaction under Opinion 16; and

    WHEREAS, the Board of Directors of the Company deems it desirable and in the
best interest of the Company and its shareholders that the Company enter into
this Agreement with Buyer, pursuant to which, subject to the directions of the
High Court, the Company will propose to its shareholders to agree to the Scheme,
subject to the conditions set forth herein; and

    WHEREAS, for the purpose of implementing the Scheme, it will be necessary
for the Company to reduce and cancel the existing share capital of the Company,
and the Company will accordingly propose to its shareholders that, subject to
the confirmation of the High Court, the capital of the Company should be
appropriately reduced and cancelled; and

    WHEREAS, as a condition to, and immediately after the execution of, this
Agreement, Buyer and the Company are concurrently entering into the Stock Option
Agreement (the "COMPANY OPTION AGREEMENT") in substantially the form attached
hereto as EXHIBIT B, pursuant to which the Company will grant Buyer an option
exercisable upon the occurrence of certain events; and

    WHEREAS, as an inducement to Buyer to enter into this Agreement, John J.
Boyle III has agreed to enter into an agreement in substantially the form of
EXHIBIT C hereto to roll over all shares of unvested

                                      A-5
<PAGE>
restricted stock ("RESTRICTED STOCK") of the Company into a number of restricted
shares ("BUYER RESTRICTED STOCK") of Buyer Common Stock equal to the number of
shares of unvested Restricted Stock multiplied by the Ordinary Allotment Ratio
(as defined in Exhibit A hereto); and

    WHEREAS, the Board of Directors of Buyer deems it desirable and in the best
interest of Buyer and its shareholders that Buyer consummate the Acquisition,
including effecting the Scheme, and enter into this Agreement, pursuant to
which, among other things, (i) subject to the confirmation of the High Court,
all of the issued and outstanding Company Ordinary Shares shall be canceled and
the holders thereof shall be allotted a number of shares of Buyer Common Stock,
(ii) subject to the confirmation of the High Court, all of the issued and
outstanding Company Deferred Shares shall be canceled and the holders thereof
shall be allotted a number of shares of Buyer Common Stock, (iii) the Company
Options shall be assumed by Buyer in exchange for newly issued Buyer Options (as
defined in Section 1.1(c) hereof) (assuming the Scheme is effected), and (iv)
subject to the sanction of the Scheme by the High Court, the Company shall make
an issuance of the New Ordinary Shares and the New Deferred Shares (as each such
term is defined in Exhibit A hereto) to Buyer, on the terms and conditions
hereinafter set forth.

    NOW, THEREFORE, in consideration of the premises and of the mutual covenants
and agreements herein contained, the parties hereto, intending to be legally
bound, agree as follows:

                                      A-6
<PAGE>
                                   ARTICLE I
                     THE ACQUISITION, INCLUDING THE SCHEME

    1.1. THE ACQUISITION.  Subject to the fulfillment or waiver of the
conditions set forth in Article VII hereof:

    (a) The Company and Buyer shall, as soon as is practicable, effect the
Scheme, the terms of which, in the form attached hereto as Exhibit A or in such
other form as the Buyer and the Company shall mutually agree, are hereby
incorporated herein by reference. The parties shall use their respective best
efforts to cause the Effective Date (as defined in Exhibit A) to occur on or
before September 30, 1999. The foregoing notwithstanding, if the Effective Date
does not occur on or prior to September 30, 1999, the parties shall use their
respective best efforts to cause the Effective Date to occur as soon as
practicable thereafter. In any event, the parties shall comply with any time
limits which may be specified in the Final Court Order (as defined in Section
1.2 hereof).

    (b) The Company shall proceed in accordance with the provisions of Article V
hereof to seek the agreement of the Company's shareholders and the sanction of
the High Court for the Scheme and to seek the adoption by the Company and the
confirmation by the High Court of the resolution as to the reduction of the
capital of the Company (a "CAPITAL REDUCTION" or, together with such other
resolutions, if any, as may be brought before the shareholders at a meeting duly
called and held for such purpose, a "CAPITAL REDUCTION RESOLUTION," as the
context may require) and, subject to such agreement, sanction, adoption and
confirmation being given, shall perform all acts as are required of it by the
Scheme.

    (c) Subject to the agreement and adoption by the Company as above referred
to having been procured, to the Company proceeding with the Petition as
described (and defined) in Article V hereof and to the Scheme becoming
effective, Buyer shall perform all acts as are expressed in the Scheme to be
performed by it.

    (d) At the Effective Time (as defined in Exhibit A hereto), pursuant to the
terms of the Share Option Plan and the agreements representing the Company
Options (each as defined below) and with no further action by or on behalf of
the holders of the Company Options, each option to purchase Company Ordinary
Shares (each a "COMPANY OPTION") issued by the Company pursuant to the Company's
1995 Share Option Plan (the "SHARE OPTION PLAN") or otherwise, outstanding and
unexercised, whether or not vested or exercisable, shall be assumed by Buyer.
Each Company Option shall be deemed to constitute an option to acquire, on the
same terms and conditions as were applicable under such Company Option (after
giving effect to the accelerated vesting provisions contained in the applicable
agreements or the Share Option Plan), the number of whole shares of Buyer Common
Stock equal to the number of Company Ordinary Shares that were issuable upon
exercise of such Company Option immediately prior to the Effective Time
multiplied by the Ordinary Allotment Ratio, rounded down to the nearest whole
number of shares of Buyer Common Stock (a "BUYER OPTION"), and the per share
exercise price of the shares of Buyer Common Stock issuable upon exercise of
such Buyer Option shall be equal to the exercise price per share of Company
Ordinary Shares at which such Company Option was exercisable immediately prior
to the Effective Time divided by the Ordinary Allotment Ratio, rounded up to the
nearest whole cent. It is the intention of the parties that any assumption of
"incentive stock options" (as defined in Section 422 of the Code ("ISOS")) shall
comply with Section 424 of the Code such that ISOs so assumed by Buyer shall
qualify following the Effective Time as ISOs if and to the extent that such
Company Options qualified as ISOs prior to the Effective Time.

    (e) The parties acknowledge that the Company's 1996 Employee Stock Purchase
Plan (the "ESPP") shall continue to operate in accordance with its terms
following the execution of this Agreement, except as provided below. The Company
shall not make an Offering (as defined in the ESPP) under the ESPP for any Plan
Period (as defined in the ESPP) beginning on or after September 1, 1999.
Effective as of one business day prior to the Effective Time, the Company shall
cause the ESPP, to terminate in accordance

                                      A-7
<PAGE>
with Section 19 of the ESPP, and no purchase rights shall be subsequently
granted or exercised under the ESPP. The Company shall take all actions
necessary to ensure that the ESPP will not be amended or modified in any respect
after the date hereof, except to effect the terms of this Section 1.1(e).

    (f) If, between the date of this Agreement and the Effective Time, shares of
Buyer Common Stock shall be changed into a different number of shares or a
different class of shares by reason of any reclassification, recapitalization,
split-up, combination, exchange of shares or readjustment, or if a stock
dividend thereon shall be declared with a record date within such period, or if
a cash dividend thereon of more than $1.00 per share of Buyer Common Stock shall
be declared with a record date within such period (a "COMMON STOCK ADJUSTMENT"),
then the Ordinary Allotment Ratio shall be adjusted appropriately so as to
maintain the proportional interests of the owners of American Depositary
Receipts ("ADRS") evidencing American Depositary Shares of the Company (the
"COMPANY ADSS") (representing underlying Company Ordinary Shares) in the
outstanding shares of Buyer Common Stock in effect immediately prior to the
Common Stock Adjustment.

    (g) No fractional shares of Buyer Common Stock and no certificates or scrip
certificates therefor shall be issued to represent any such fractional interest,
and any such fractional interest shall be rounded down to the next whole share
and issued to any holder of such fractional share interest.

    (h) If, between the date of this Agreement and the Effective Time, the
Company ADSs shall be changed into a different number of shares or a different
class of shares by reason of any reclassification, consolidation, division,
subdivision or cancellation (other than the cancellation contemplated by Section
1.1(b) of this Agreement), or if a share dividend thereon shall be declared with
a record date within such period (the "ADS ADJUSTMENT"), then the Ordinary
Allotment Ratio in respect of the ADSs shall be adjusted appropriately so as to
maintain the proportional interests of the owners of the Company ADSs in the
outstanding shares of Buyer Common Stock in effect immediately prior to the ADS
Adjustment.

    1.2. DELIVERY OF ORDER.  As soon as practicable after the fulfillment or
waiver of the conditions set forth in Article VII hereof, or on such later date
as may be mutually agreed to between Buyer and the Company, the Company and
Buyer will cause to be delivered to the Registrar of Companies in Dublin,
Ireland, a copy of the final court order of the High Court sanctioning the
Scheme and the order of the High Court confirming the Capital Reduction (the
"FINAL COURT ORDER") and the minute required by Section 75 of the Companies Act,
as described in Article V hereof.

                    EXCHANGE OF AMERICAN DEPOSITARY RECEIPTS
                       AND ASSUMPTION OF COMPANY OPTIONS

    2.1. APPOINTMENT OF ALLOTMENT AGENT.  Buyer shall authorize a commercial
bank, trust company or other financial institution, which may be the Custodian
(as defined in the Deposit Agreements between the Company and the holders of
ADRs (the "DEPOSIT AGREEMENT") or the Depositary (as defined in the Deposit
Agreement), to act as Allotment Agent ("ALLOTMENT AGENT") for the holders of
ADRs prior to the hearing on the Petition which authorization shall be subject
to the approval of the Company, which approval shall not be unreasonably
withheld or delayed. In accordance with and subject to the provisions of this
Agreement and the Allotment Agent Agreement between Buyer and the Allotment
Agent, if any, or the Deposit Agreement, as the case may be, at the Effective
Time, Buyer shall deliver, or cause to be delivered, a number of shares of Buyer
Common Stock equal to the Ordinary Allotment Ratio multiplied by the total
number of issued and outstanding Company ADSs as of the Effective Time (together
with any dividends or distributions with respect to the Buyer Common Stock, the
"ALLOTMENT FUND") to the Allotment Agent. The Allotment Agent shall hold the
Allotment Fund for the benefit of holders of ADRs evidencing Company ADSs. The
Allotment Agent shall distribute the Allotment Fund pursuant to this Article II.

    2.2. SURRENDER AND ALLOTMENT PROCEDURE.  The surrender and allotment
procedure for the ADRs pursuant to the terms of the Acquisition shall be as set
forth below, subject to the terms of the Deposit Agreement(s), or as may be
mutually agreed upon by the Company, the Buyer and the Depositary (as defined in
Section 2.2(b) below).

    (a) At and after the Effective Time (subject to Section 2.2(h) hereof), each
holder of record of any outstanding Company ADSs shall be entitled, upon
surrender to the Allotment Agent of the ADRs representing Company ADSs and such
other documents as the Allotment Agent may request, to receive therefor an
allotment of shares of Buyer Common Stock equal to the Ordinary Allotment Ratio
multiplied by the number of Company Ordinary Shares underlying the Company ADSs
evidenced by such ADRs so surrendered, as shall be more particularly provided in
the Allotment Agent Agreement.

    (b) On or before the third business day following the Effective Time, Buyer
will cause the Allotment Agent to send a notice and a transmittal form to the
Depositary for the Company ADSs, advising such holder of the terms of the
Acquisition and the procedure for the surrender of ADRs evidencing the Company
ADSs and allotment of the shares of Buyer Common Stock as provided in the
Allotment Agent Agreement.

    (c) Upon receipt from the Depositary of the completed transmittal form and
the ADRs, Buyer shall cause the Allotment Agent to deliver to the Depositary the
requisite number of shares of Buyer Common Stock from the Allotment Fund for
distribution to the holders of the Company ADSs. Subject to the terms of the
Deposit Agreement(s), Buyer shall cause the Depositary to send each holder of
the Company ADSs a notice informing such holders that the Deposit Agreement(s)
will terminate one year after the Effective Time and instructing each such
holder to surrender the ADRs evidencing their Company ADSs to the Depositary in
exchange for the allotment of shares of Buyer Common Stock. Upon receipt of such
ADRs, Buyer shall cause the Depositary to deliver the number of shares of Buyer
Common Stock allotted for each Company ADS received to the holders thereof.

    (d) No dividends or other distributions declared or made with respect to
Buyer Common Stock with a record date after the Effective Time shall be paid to
the holder of any unsurrendered ADR with respect to the shares of Buyer Common
Stock represented thereby until the holder of such ADR shall surrender such ADR.
Subject to the effect of escheat, tax or other applicable laws, following
surrender of any such ADR, there shall be paid to the holder, without interest,
(i) the amount of dividends or other distributions with a record date after the
Effective Time theretofore paid with respect to the whole shares of Buyer Common

                                      A-9
<PAGE>
Stock which the holder was allotted pursuant to the Acquisition, and (ii) at the
appropriate payment date, the amount of dividends or other distributions, with a
record date after the Effective Time but prior to surrender and a payment date
occurring after surrender, payable with respect to the whole shares of Buyer
Common Stock which the holder was allotted pursuant to the Acquisition.

    (e) All shares of Buyer Common Stock issued upon cancellation of the Company
Ordinary Shares underlying the Company ADSs in accordance with the Scheme and
the terms of this Agreement (including any cash paid pursuant to Section 2.2(d)
hereof) shall be deemed to have been issued in full satisfaction of all rights
pertaining to such Company ADSs.

    (f) Neither Buyer nor the Company shall be liable to any holder of ADRs
evidencing Company ADSs for any such shares of Buyer Common Stock (or dividends
or distributions with respect to such shares) or cash delivered to a public
official in compliance with any abandoned property, escheat or similar law.

    (g) From the Effective Time, each ADR that, prior to the Effective Time,
represented Company ADSs shall cease to be of any value and shall not entitle
the holders thereof to any rights whatsoever, except to evidence the right to
receive the allotment of shares of Buyer Common Stock equal to the Ordinary
Allotment Ratio multiplied by the number of Company Ordinary Shares underlying
the Company ADSs evidenced by such ADR. No interest shall be paid with respect
to the allotments of shares of Buyer Common Stock pursuant to the Acquisition,
regardless of when delivered to the holders of ADRs.

    (h) Any portion of the Allotment Fund that remains unclaimed by the former
ADR holders of the Company for one (1) year after the Effective Time shall be
delivered by the Allotment Agent to Buyer, upon demand of Buyer, and any former
ADR holders of the Company shall thereafter look only to Buyer for satisfaction
of their claim for an allotment of shares of Buyer Common Stock in respect of
Company ADSs pursuant to the terms of this Section 2.2.

    (i) Any person claiming an ADR to have been lost, stolen or destroyed shall
comply with the applicable terms of the Deposit Agreements.

    2.3. EXCHANGE OF SHARE OPTIONS.

    (a) As soon as practicable after the Effective Time, but no later than two
business days after the Effective Time, Buyer shall inform in writing the
holders of Company Options of their rights pursuant to the Share Option Plan and
the agreements evidencing the grants of such Company Options shall continue in
effect on the same terms and conditions (subject to the adjustments required by
Section 1.1(d) hereof), after giving effect to the Acquisition and the
assumption by Buyer as set forth herein.

    (b) Buyer shall take all corporate action necessary to reserve for issuance
a sufficient number of shares of Buyer Common Stock for delivery upon exercise
of the Company Options assumed in accordance with Section 1.1(d) hereof and to
file all documents required to be filed to cause the shares of Buyer Common
Stock issuable upon exercise of the Buyer Options to be listed on the Nasdaq
National Market. Promptly after the Effective Time, but no later than one (1)
day after the Effective Date, Buyer shall file a registration statement with the
U.S. Securities and Exchange Commission (the "SEC") on Form S-8 (or any
successor form) or another appropriate form with respect to shares of Buyer
Common Stock subject to such options and Buyer shall use all reasonable efforts
to maintain the effectiveness of such registration statement or registration
statements (and maintain the current status of the prospectuses contained
therein) for so long as any such options remain outstanding.

                                  ARTICLE III
                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

    The Company represents and warrants to Buyer that the statements contained
in this Article III are true and correct, except as set forth in the letter
delivered by the Company to Buyer on the date hereof (the "COMPANY DISCLOSURE
LETTER") (which Company Disclosure Letter sets forth the exceptions to the
representations and warranties contained in this Article III). The Company
Disclosure Letter shall be arranged in sections corresponding to the Sections in
this Article III to which the exceptions apply and the disclosure in any such
section shall qualify the other Sections in this Article III to the extent that
it is reasonably apparent from a reading of such disclosure that it also
qualifies or applies to such other Sections; PROVIDED that the Company shall use
commercially reasonable efforts, including specific cross-references to the
Sections, to identify the other Sections to which such disclosure applies.

    3.1. ORGANIZATION AND QUALIFICATION.  Each of the Company and its
Subsidiaries (as defined below) is a company (or similar entity with corporate
characteristics including limited liability of shareholders) duly organized,
validly existing, duly registered and, if applicable, in good standing under the
laws of the jurisdiction of its organization and each such entity has all
requisite corporate power and authority to own, lease and operate its properties
and to carry on its business as now being conducted, except where any failure
would not reasonably be expected to have a Company Material Adverse Effect (as
defined below). Each of the Company and its Subsidiaries is duly qualified or
licensed to carry on its business as it is now being conducted, and is qualified
to conduct business, in each jurisdiction where the character of its properties
owned or leased or the nature of its activities makes such qualification
necessary, except for failures to be so qualified that would not, individually
or in the aggregate, have, or would not reasonably be expected to have, a
Company Material Adverse Effect. Neither the Company nor any of its Subsidiaries
is in violation of any of the provisions of its Memorandum and Articles of
Association, Certificate of Incorporation or other applicable charter document
(any such document of any business entity hereinafter referred to as its
"CHARTER DOCUMENT") or its Memorandum of Association, ByLaws, or other
applicable governing document (any such documents of any business entity
hereinafter referred to as its "GOVERNING DOCUMENT"). The Company has made
available to Buyer accurate and complete copies of the respective Charter
Documents and Governing Documents, as currently in effect, of each of the
Company and its Subsidiaries. As used in this Agreement, the term "COMPANY
MATERIAL ADVERSE EFFECT" means any change, effect, event or condition that (i)
has a material adverse effect on the business, results of operations or
financial condition of the Company and its Subsidiaries, taken as a whole (other
than any such change, effect, event or condition that results or arises from:
(A) the announcement of this Agreement or the transactions contemplated hereby
and the consequences of such announcement, to the extent directly related
thereto; (B) changes or conditions effecting the industry in which the Company
markets its products and services generally, except to the extent such changes
or conditions disproportionately affect the Company and its Subsidiaries, taken
as a whole; (C) changes in general economic, regulatory or political conditions,
except to the extent such changes or conditions disproportionately affect the
Company and its Subsidiaries, taken as a whole; or (D) any action taken by Buyer
or any of its directors, officers, employees, agents or affiliates; and PROVIDED
that, a failure by the Company to meet the revenue or earnings predictions of
equity analysts as reflected in the First Call consensus estimate or any other
revenue or earnings predictions or expectations for any period ending on or
after the date of this Agreement shall not, in and of itself, be deemed to
constitute a Company Material Adverse Effect), or (ii) prevents or materially
delays the Company's ability to consummate the transactions contemplated hereby.
As used in this Agreement, the term "SUBSIDIARY" when used with respect to any
party means any corporation or other organization, whether incorporated or
unincorporated, of which such party directly or indirectly owns or controls at
least a majority of the securities or other interests having by their terms
ordinary voting power to elect a majority of the board of directors or others
performing similar functions.

    3.2. CAPITAL STOCK OF SUBSIDIARIES.  Neither the Company nor any of its
Subsidiaries owns, controls or holds with the power to vote, directly or
indirectly, of record, beneficially or otherwise, any share capital,

                                      A-11
<PAGE>
capital stock or any equity or ownership interest in any company, corporation,
partnership, association, joint venture, business, trust or other entity, except
for the Subsidiaries described in the Company SEC Reports (as defined in Section
3.6(a) hereof) or as listed in Section 3.2 of the Company Disclosure Letter, and
except for ownership of securities in any publicly traded company held for
investment by the Company or any of its Subsidiaries and comprising less than
five percent of the outstanding stock of such company. Except as set forth in
Section 3.2 of the Company Disclosure Letter, the Company is directly or
indirectly the registered, record and beneficial owner of all of the outstanding
share capital or shares of capital stock (or other ownership interests having by
their terms ordinary voting power to elect a majority of directors or others
performing similar functions with respect to such Subsidiary) of each of its
Subsidiaries, there are no proxies with respect to such shares, and no equity
securities of any of such Subsidiaries are or may be required to be issued by
reason of any options, warrants, scrip, rights to subscribe for, calls or
commitments of any character whatsoever relating to, or securities or rights
convertible into or exchangeable for, share capital or shares of any capital
stock of any such Subsidiary, and there are no contracts, commitments,
understandings or arrangements by which the Company or any such Subsidiary is
bound to issue, transfer or sell any share capital or shares of such capital
stock or securities convertible into or exchangeable for such shares. Other than
as set forth in Section 3.2 of the Company Disclosure Letter, all of such shares
so owned by the Company are validly issued, fully paid and nonassessable and are
owned by it free and clear of any claim, lien, pledge, security interest or
other encumbrance of any kind (collectively "LIENS") with respect thereto.

    3.3. CAPITALIZATION.  The authorized share capital of the Company is US
$187,500 divided into 75,000,000 Ordinary Shares of $0.0025 each, and IRL30,000
divided into 30,000 Deferred Shares of IRL1.00 each. As of the close of business
on May 31, 1999 (the "COMPANY MEASUREMENT DATE"), (a) 39,194,170 Company
Ordinary Shares were issued and outstanding, (b) 30,000 Company Deferred Shares
were issued and outstanding, (c) the Company had no treasury shares within the

Ordinary Shares were reserved for issuance under the Share Option Plan and the
ESPP, (e) Company Options had been granted and remain outstanding under the
Share Option Plan to purchase 7,023,719 Company Ordinary Shares in the
aggregate, and (f) except for the Company Options and rights to the issuance of
367,954 Company Ordinary Shares in the aggregate under the ESPP, there are no
outstanding Rights (defined below). Since the Company Measurement Date, no
additional shares in the Company have been issued, except pursuant to the
exercise of Company Options and the ESPP and no Rights have been granted. Except
as described in the preceding sentence, the Company has no outstanding bonds,
debentures, notes or other securities or obligations the holders of which have
the right to vote or which are convertible into or exercisable for securities
having the right to vote on any matter on which any shareholder of the Company
has a right to vote. All issued and outstanding Company Ordinary Shares are duly
authorized, validly issued, fully paid, nonassessable and free of preemptive
rights. There are not at the date of this Agreement any existing options,
warrants, calls, subscriptions, convertible securities or other rights which
obligate the Company or any of its Subsidiaries to issue, exchange, transfer or
sell any shares in the capital of the Company or any of its Subsidiaries other
than Company Ordinary Shares issuable pursuant to Company Options and the ESPP,
or awards granted pursuant thereto (collectively, "RIGHTS"). As of the Company
Measurement Date, there were no outstanding contractual obligations of the
Company or any of its Subsidiaries to repurchase, redeem or otherwise acquire
any shares in the capital of the Company or any of its Subsidiaries. As of the
Company Measurement Date, there were no outstanding contractual obligations of
the Company to vote or to dispose of any shares in the capital of any of its
Subsidiaries.

    3.4. AUTHORITY RELATIVE TO THIS AGREEMENT.  The Company has the requisite
corporate power and authority to execute and deliver, and perform its
obligations under, this Agreement and the Company Option Agreement, subject to
obtaining the necessary approvals of its shareholders and of the High Court as
referred to in Section 3.5(b)(i)(B) hereof, under applicable law. The execution
and delivery of this Agreement and the Company Option Agreement and the
consummation of the Scheme and other transactions contemplated hereby and
thereby have been duly and validly authorized by the Board of

                                      A-12
<PAGE>
Directors of the Company and no other corporate proceedings on the part of the
Company are necessary to authorize this Agreement or the Company Option
Agreement or to consummate the Scheme or other transactions contemplated hereby
and thereby (other than approvals by the Company's shareholders required by
applicable law, and the making of the Final Court Order). This Agreement and the
Company Option Agreement have been duly and validly executed and delivered by
the Company and, assuming the due authorization, execution and delivery hereof
by Buyer, each constitutes a valid and binding agreement of the Company,
enforceable against the Company in accordance with its terms, except to the
extent that its enforceability may be limited by applicable bankruptcy,
insolvency, reorganization, moratorium or other laws affecting the enforcement
of creditors rights generally or by general equitable principles.

    3.5. NO CONFLICT; REQUIRED FILINGS AND CONSENTS.

    (a) Assuming that all filings, permits, authorizations, consents and
approvals or waivers thereof have been duly made or obtained as contemplated by
Section 3.5(b) hereof, neither the execution and delivery of this Agreement or
the Company Option Agreement by the Company nor the consummation of the Scheme
or other transactions contemplated hereby nor compliance by the Company with any
of the provisions hereof will (i) violate, conflict with, or result in a breach
of any provision of, or constitute a default (or an event which, with notice or
lapse of time or both, would constitute a default) under, or result in the
termination or suspension of, or accelerate the performance required by, or
result in a right of termination or acceleration under, or result in the
creation of any Lien upon any of the properties or assets of the Company or any
of its Subsidiaries under, any of the terms, conditions or provisions of (x)
their respective Charter Documents or Governing Documents, (y) any note, bond,
charge, lien, pledge, mortgage, indenture or deed of trust to which the Company
or any such Subsidiary is a party or to which they or any of their respective
properties or assets may be subject, or (z) any license, lease, agreement or
other instrument or obligation to which the Company or any such Subsidiary is a
party or to which they or any of their respective properties or assets may be
subject, or (ii) violate any judgment, ruling, order, writ, injunction, decree,
statute, rule or regulation applicable to the Company or any of its Subsidiaries
or any of their respective properties or assets, except, in the case of clauses
(i) (y) and (z) and (ii) above, for such violations, conflicts, breaches,
defaults, terminations, suspensions, accelerations, rights of termination or
acceleration or creations of liens, security interests, charges or encumbrances
which would not, individually or in the aggregate, reasonably be expected to
have a Company Material Adverse Effect.

Material Adverse Effect, and neither the Company nor any Subsidiary is in
default in any material respect with respect to any such Order.

    3.10. CERTAIN CONTRACTS.  Neither the Company nor any of its Subsidiaries
has breached, or received in writing any claim or notice that it has breached,
any of the terms or conditions of (i) any agreement, contract or commitment
required to be filed as an exhibit to the Company SEC Reports (including any

required to be filed by the Company with the SEC in any report covering the
period ending June 30, 1999), (ii) any agreements, contracts or commitments with
customers of the Company pursuant to which the Company recognized revenues in

ability of the Company or any of its

                                      A-15
<PAGE>
Subsidiaries to compete in any line of business or with any Person (as defined
in Section 9.5 hereof), or that include any exclusivity provision or involve any
restriction on the geographic area in which the Company or any of its
Subsidiaries may carry on its business (collectively, "COMPANY MATERIAL
CONTRACTS"), in such a manner as, individually or in the aggregate, has had or
would reasonably be expected to have a Company Material Adverse Effect. Section
3.10 of the Company Disclosure Letter lists each Company Material Contract
described in clauses (ii) and (iii) of the preceding sentence. Each Company
Material Contract that has not expired by its terms is in full force and effect
and is the legal, valid and binding obligation of the Company and/or its
Subsidiaries, enforceable against them in accordance with its terms, subject to
applicable bankruptcy, insolvency, reorganization, moratorium and similar laws
affecting creditors' rights and remedies generally and subject, as to
enforceability, to general principles of equity (regardless of whether
enforcement is sought in a proceeding at law or in equity), except where the
failure of such Contract to be in full force and effect or to be legal, valid,
binding or enforceable against the Company and/or its Subsidiaries has not had
and would not, individually or in the aggregate, reasonably be expected to have
a Company Material Adverse Effect. Except as set forth in Section 3.10 of the
Company Disclosure Letter, no consent, approval, waiver or authorization of, or
notice to any Person is needed in order that each such Company Material Contract
shall continue in full force and effect in accordance with its terms without
penalty, acceleration or rights of early termination by reason of the
consummation of the Scheme and the other transactions contemplated by this
Agreement.

    3.11. COMPLIANCE WITH LAW.  All activities of the Company and its
Subsidiaries have been, and are currently being, conducted in compliance in all
material respects with all applicable Irish, Canadian, Australian, United States
federal, state and local and other foreign laws, ordinances, regulations,
interpretations, judgments, decrees, injunctions, permits, licenses,
certificates, governmental requirements, Orders and other similar items of any
court or other Governmental Entity or any nongovernmental self-regulatory
agency, and no notice has been received by the Company of any claims filed
against the Company alleging a violation of any such laws, regulations or other
requirements which would be required to be disclosed in the Company SEC Reports.
The Company and its Subsidiaries have all permits, licenses and franchises from
Governmental Entities required to conduct their businesses as now being
conducted, except for such permits, licenses and franchises the absence of which
has not had and would not, individually or in the aggregate, reasonably be
expected to have a Company Material Adverse Effect.

    3.12. INTELLECTUAL PROPERTY RIGHTS.

    (a) The Company and its Subsidiaries own, or are licensed or otherwise
possess legally enforceable rights to use, all patents, trademarks, trade names,

processes, formulae, methods, schematics, technology, know-how, computer
software programs or applications and tangible or intangible proprietary
information or material that are necessary to conduct the business of the
Company and its Subsidiaries as currently conducted, or planned to be conducted,
the absence of which would be reasonably likely to have a Company Material
Adverse Effect (the "COMPANY INTELLECTUAL PROPERTY RIGHTS"). The Company and its
Subsidiaries have taken all reasonably necessary action to protect the Company
Intellectual Property Rights, including without limitation, use of reasonable
secrecy measures to protect the trade secrets included in the Company
Intellectual Property Rights.

    (b) The execution and delivery of this Agreement and consummation of the
transactions contemplated hereby will not result in the breach of, or create on
behalf of any third party the right to terminate or modify, any license,
sublicense or other agreement relating to the Company Intellectual Property
Rights, or any material licenses, sublicenses or other agreements as to which
the Company or any of its Subsidiaries is a party and pursuant to which the
Company or any of its Subsidiaries is authorized to use any third party patents,
trademarks, copyrights or trade secrets ("COMPANY THIRD PARTY INTELLECTUAL
PROPERTY RIGHTS"), including software that is used in the manufacture of,
incorporated in, or forms a part of any

                                      A-16

Subsidiaries, the breach of which would, individually or in the aggregate, be
reasonably likely to have a Company Material Adverse Effect.

    (c) All patents, registered trademarks, service marks and copyrights which
are held by the Company or any of its Subsidiaries, the loss or invalidity of
which would reasonably be expected to cause a Company Material Adverse Effect,
are valid and subsisting. The Company (i) has not been sued in any suit, action
or proceeding, or received in writing any claim or notice, which involves a
claim of infringement of any patents, trademarks, service marks, copyrights or
violation of any trade secret or other proprietary right of any third party; and

its products infringes any patent, trademark, service mark, copyright, trade
secret or other proprietary right of any third party, which infringement in the

be expected to have a Company Material Adverse Effect.

    interruption before, during and after January 1, 2000, without any change of
    operations associated with the advent of the new century;

referencing this Section 3.15(c), no condition, agreement or plan provision or,

that would not, individually or in the aggregate, reasonably be expected to have
a Company Material Adverse Effect, and (ii) neither the Company nor any of its
Subsidiaries, directors, officers, employees or other "fiduciaries," as such
term is defined in Section 3(21) of ERISA, have committed any breach of
fiduciary responsibility imposed by ERISA or any other applicable law with
respect to the plans which would subject the Company, Subsidiary, Buyer, or any
of its directors, officers or employees to any liability under ERISA or any
applicable law, except any breach that would not, individually or in the

                                   ARTICLE IV
                    REPRESENTATIONS AND WARRANTIES OF BUYER

    Buyer represents and warrants to the Company that the statements contained
in this Article IV are true and correct.

    4.1. ORGANIZATION AND QUALIFICATION.  Buyer is a corporation duly organized,
validly existing, duly registered and in good standing under the laws of the
State of Minnesota, with the corporate power and authority to own, lease and
operate its properties and to carry on its business as now being conducted,
except where any failure would not have a Buyer Material Adverse Effect (as
defined below). Buyer is duly qualified or licensed to carry on its business as
it is now being conducted, and is qualified to conduct business, in each
jurisdiction where the character of its properties owned or leased or the nature
of its activities makes such qualification necessary, except for failures to be
so qualified that would not, individually or in the aggregate, have, or would
not reasonably be expected to have, a Buyer Material Adverse Effect. Buyer is
not in violation of any of the provisions of its Charter Document or its
Governing Document. As used in this Agreement, the term "BUYER MATERIAL ADVERSE
EFFECT" means any change, effect, event or condition that (i) has a material
adverse effect on the business, results of operations or financial condition of
Buyer and its Subsidiaries, taken as a whole (other than any such change,
effect, event or condition that results or arises from: (A) the announcement of
this Agreement or the transactions contemplated hereby and the consequences of
such announcement, to the extent directly related thereto; (B) changes or
conditions effecting the industry in which Buyer markets its products and
services generally, except to the extent such changes or conditions
disproportionately affect Buyer and its Subsidiaries, taken as a whole; (C)
changes in general economic, regulatory or political conditions, except to the
extent such changes or conditions disproportionately affect Buyer and its
Subsidiaries, taken as a whole; or (D) any action taken by the Company or any of
its directors, officers, employees, agents or affiliates; and PROVIDED that, a
failure by Buyer to meet the revenue or earnings predictions of equity analysts
as reflected in the First Call consensus estimate or any other revenue or
earnings predictions or expectations for any period ending on or after the date
of this Agreement shall not, in and of itself, be deemed to constitute a Buyer
Material Adverse Effect), or (ii) prevents or materially delays Buyer's ability
to consummate the transactions contemplated hereby.

    4.2. CAPITALIZATION.  The authorized capital stock of Buyer consists of
310,000,000 shares, divided into 300,000,000 shares of Buyer Common Stock and
10,000,000 shares of Preferred Stock, no par value. As of the close of business
on June 18, 1999 (the "Buyer Measurement Date"), (a) 135,636,594 shares of Buyer
Common Stock were issued and outstanding, (b) no shares of Preferred Stock were
issued and outstanding, (c) 25,400,846 shares of Buyer Common Stock were
reserved for issuance under the stock-based benefit plans of the Buyer (the

ESPP") and rights to acquire shares of Buyer Common Stock pursuant to the Second
Amended and Restated Rights Agreement, dated as of November 28, 1995, between
Buyer and Norwest Bank, Minnesota, National Association (the "BUYER SRP PLAN",

Measurement Date, no additional shares of Buyer Common Stock have been issued
and are outstanding, except pursuant to the exercise of Buyer Options and the
Buyer ESPP, and no Buyer Rights have been granted (other than additional Buyer
SRP Rights issued upon the issuance of shares of Buyer Common Stock). All issued
and outstanding shares of Buyer Common Stock are duly authorized, validly
issued, fully paid, nonassessable and free of preemptive rights created by the
Minnesota Business Corporation Act or Buyer's Charter Document or Governing
Document. There are not at the date of this Agreement any existing options,
warrants, calls, subscriptions, convertible securities or other rights which
obligate Buyer or any of its Subsidiaries to issue, exchange, transfer or sell
any shares of capital stock of Buyer or any of its Subsidiaries, other than
shares of Buyer Common Stock issuable under the Buyer Stock Plans and the Buyer
ESPP, or awards granted pursuant

                                      A-22
<PAGE>
thereto, and other than Buyer SRP Rights issued upon the issuance of additional
shares of Buyer Common Stock (collectively, "BUYER RIGHTS"). As of the Buyer
Measurement Date, there were no outstanding contractual obligations of Buyer or
any of its Subsidiaries to repurchase, redeem or otherwise acquire any shares of
capital stock of Buyer or any of its Subsidiaries. As of the Buyer Measurement
Date, there were no outstanding contractual obligations of Buyer to dispose of
any shares of capital stock of any of its Subsidiaries.

principles. The shares of Buyer Common Stock to be issued by Buyer and allotted
pursuant to the Acquisition, as well as the Buyer Options and the shares of

of any country other than the United States and the Republic of Ireland, or (ii)
where the failure to obtain any such consents, approvals, authorizations or

the aggregate, reasonably be expected to have a Buyer Material Adverse Effect.

    (a) Buyer has filed all forms, reports, schedules, statements and other
documents required to be filed by it since October 31, 1996 to the date hereof

material respects with all applicable requirements of the Securities Act and the
Exchange Act, as the case may be, and (ii) did not at the time they were filed
contain any untrue statement of a material fact or omit to state any material

requirements which

                                      A-24
<PAGE>
would be required to be disclosed in the Buyer SEC Reports. Buyer has all
permits, licenses and franchises from Governmental Entities required to conduct
its business as now being conducted, except for such permits, licenses and
franchises the absence of which would not, individually or in the aggregate,
reasonably be expected to have a Buyer Material Adverse Effect.

circumstances, that (without regard to any action taken or agreed to be taken by
the Company or any of its affiliates) would prevent the business combination to
be effected by the Acquisition from constituting a transaction qualifying as a

(other than written statements supplied by Buyer in writing specifically for

statements supplied by Buyer specifically for inclusion in the Proxy Statement
shall not include 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

Company and to the extent permitted by applicable laws, including the Companies
Acts 1963-1990 of Ireland, the Company's Board of Directors shall state that it
recommends that the Company's shareholders approve the Scheme and the Capital
Reduction Resolution. The Proxy Statement shall be reviewed and approved by

as mutually agreed by Buyer and Company to be necessary to discharge their
respective obligations under United States and Irish

publication of any press release or make any other public announcement with
respect to the transactions contemplated by this Agreement without the consent
of the other party, which consent shall not be unreasonably withheld or delayed.
Buyer and the Company will cooperate with each other in the development and
distribution of all press releases and other public announcements with respect
to this Agreement and the transactions

                                      A-30
<PAGE>
contemplated hereby, and will furnish the other with drafts of any such releases
and announcements as far in advance as possible.

    6.6. NO SOLICITATION.

    (a) Immediately upon execution of this Agreement, the Company shall (and
shall cause its officers, directors, employees, investment bankers, attorneys
and other agents to) cease all discussions, negotiations, responses to inquiries
(except as set forth in the proviso to this sentence) and other communications
relating to any potential business combination with all third parties who, prior
to the date hereof, may have expressed or otherwise indicated any interest in
pursuing an Acquisition Proposal with the Company; PROVIDED that, if any such
inquiries are made after the date hereof, the Company shall respond by stating
that it is a party to a binding agreement with Buyer and is prohibited thereby
from further responding to such inquiries.

    (b) Prior to termination of this Agreement pursuant to Article VIII hereof,
the Company and its Subsidiaries will not, nor shall the Company authorize or
permit any officers, directors or employees of, or any investment bankers,
attorneys or other agents retained by or acting on behalf of, the Company or any
of its Subsidiaries to, (i) initiate, solicit or encourage, directly or
indirectly, any inquiries or the making of any proposal that constitutes an
Acquisition Proposal (as hereinafter defined), (ii) except as permitted below,
engage or participate in negotiations or discussions with, or furnish any
information or data to, or take any other action to, facilitate any inquiries or
making any proposal by, any third party relating to an Acquisition Proposal, or
(iii) except as permitted below, enter into any agreement with respect to any
Acquisition Proposal or approve an Acquisition Proposal. Notwithstanding
anything to the contrary contained in this Section 6.6 or in any other provision
of this Agreement, prior to the Company Shareholders Meeting, the Company and
its Board of Directors (the "COMPANY BOARD") may participate in discussions or
negotiations with or furnish information to any third party making an
unsolicited Acquisition Proposal (a "POTENTIAL ACQUIROR") or approve or
recommend an unsolicited Acquisition Proposal if both (A) a majority of the
directors of the Company Board, without including directors who have a financial
interest in such Acquisition Proposal or who are or may be considered Affiliates
(as defined in Rule 405 under the Securities Act), or "connected persons" (as
defined in Section 26 of the Irish Companies Act, 1990), of any person making an
Acquisition Proposal ("DISINTERESTED DIRECTORS") determines in good faith, after
receiving advice from its financial advisor, that a Potential Acquiror has
submitted to the Company an Acquisition Proposal that is a Superior Proposal (as
hereinafter defined), and (B) a majority of the disinterested directors of the
Company Board determines in good faith, after receiving advice from reputable
outside legal counsel experienced in such matters (and the parties hereto agree
that the law firms of Hale and Dorr LLP and McCann FitzGerald are so
experienced), that the failure to participate in such discussions or
negotiations or to furnish such information is inconsistent with the Company
Board's fiduciary duties under applicable law. In the event that the Company
shall receive any Acquisition Proposal, it shall promptly (and in no event later
than 24 hours after receipt thereof) furnish to Buyer the identity of the
recipient of such information and of the Potential Acquiror, the terms of such
Acquisition Proposal, copies of all such information, and shall further promptly
inform Buyer in writing as to the fact such information is to be provided after
compliance with the terms of the preceding sentence. Nothing contained herein
shall prevent the Company from complying with Rules 14d-9 and 14e-2 promulgated
under the Exchange Act with regard to an Acquisition Proposal or making any
disclosure to the Company's shareholders if, in the good faith judgment of the
Company Board, after receiving advice from reputable outside legal counsel
experienced in such matters (and the parties hereto agree that the law firms of
Hale and Dorr LLP and McCann FitzGerald are so experienced), such disclosure is
required by applicable law. Without limiting the foregoing, the Company
understands and agrees that any violation of the restrictions set forth in this
Section 6.6(b) shall be deemed to be a breach of this Section 6.6(b) sufficient
to enable Buyer to terminate this Agreement pursuant to Section 8.1(d)(i)
hereof.

        (c) DELIVERY OF CLOSING DOCUMENTS. At or prior to the Effective Time,
    the Buyer shall have delivered to the Company a certificate of the President
    and the Chief Financial Officer of Buyer, dated as of the Effective Date,
    stating that the conditions precedent set forth in Sections 7.3(a) and (b)
    hereof have been satisfied.

        (d) TAX OPINION. The Company shall have received the opinion of Hale and
    Dorr LLP, counsel to the Company, to the effect that the Acquisition will be
    treated for U.S. federal income tax purposes as a reorganization within the
    meaning of Section 368(a) of the Code and that accordingly, solely for U.S.
    federal tax purposes; PROVIDED that, if Hale and Dorr LLP does not render
    such opinion, this condition shall nonetheless be deemed satisfied if Dorsey
    & Whitney LLP renders such opinion to the Company (it being agreed that
    Buyer and the Company shall each provide reasonable cooperation, including
    making reasonable representations, to Hale and Dorr LLP or Dorsey & Whitney
    LLP, as the case may be, to enable them to render such opinion).

Agreement pursuant to this Section 8.1(iv) unless (a) the Company has delivered
to Buyer a written notice of the Company's intent to enter into such an
agreement to effect such Acquisition Proposal, which notice shall include,
without limitation, the material terms and conditions of the Acquisition
Proposal and the identity of the Person making the Acquisition Proposal, and (b)

period, the Board of Directors of the Company continues reasonably to believe

and warranties contained in Article IV hereof which breach has or is reasonably
likely to have a Buyer Material Adverse Effect or Buyer shall have breached or

agreements contained in this Agreement, in each case, which breach or failure to
perform has not been cured by Buyer within thirty (30) days following receipt of
notice thereof from the Company; or

    (d) by Buyer:

    (i) if the Company shall have breached any of its representations and
warranties contained in Article III hereof which breach has or is reasonably
likely to have a Company Material Adverse Effect or the Company shall have
breached or failed to perform in any material respect any of its covenants or
other agreements contained in this Agreement, in each case, which breach or
failure to perform has not been cured by the Company within thirty (30) days

recommendation of the Scheme, the Capital Reduction Resolution or this
Agreement, or approved or recommended an Acquisition Proposal (including a
Superior Proposal), or (b) the Board of Directors of the Company or any
committee thereof shall have resolved to take any of the foregoing actions; or

                                      A-38

    (iii) at any time after 6:00 a.m. Minneapolis time on June 21, 1999, if the
Company Option Agreement shall not have been executed and delivered by the
Company to Buyer prior to such termination.

    8.2. EFFECT OF TERMINATION.  The termination of this Agreement pursuant to
the terms of Section 8.1 hereof shall become effective upon delivery to the
other party of written notice thereof. In the event of the termination of this
Agreement pursuant to the foregoing provisions of this Article VIII, this
Agreement shall become void and have no effect, with no liability on the part of
either party (except as provided in Section 8.3 hereof) or its shareholders or
directors or officers in respect thereof, EXCEPT for agreements which survive
the termination of this Agreement, EXCEPT for liability that Buyer or the
Company might have to the other party arising from a breach of this Agreement
due to termination of this Agreement in accordance with Sections 8.1(c) or
8.1(d); or due to the fraudulent or willful misconduct of such party, and EXCEPT
that any termination shall not affect the Company Option Agreement.

    8.3. FEES AND EXPENSES.

    (a) Except as provided in this Section 8.3, whether or not the Acquisition

8.1(d)(i) or 8.1(d)(ii) hereof then, in each case, the Company shall (without
prejudice to any other rights Buyer may have against the Company for breach of
this Agreement), reimburse Buyer upon demand for all out-of-pocket fees and
expenses incurred or paid by or on behalf of Buyer or any Affiliate of Buyer in
connection with this Agreement, the Scheme and transactions contemplated herein,
including all fees and expenses of counsel, investment banking firms,
accountants and consultants, up to a maximum aggregate amount of $1,500,000.

    (c) Notwithstanding any other provision in this Agreement to the contrary,
if (x) this Agreement is terminated by the Company or Buyer at a time when Buyer
is entitled to terminate this Agreement pursuant to Section 8.1(b)(ii) or
8.1(d)(i) (other than due to a breach of Section 6.6(b) hereof) and,
concurrently with or (1) within nine months after such a termination, (A) the
Company shall enter into an agreement, arrangement or binding understanding with
respect to an Acquisition Proposal (which shall include, for this purpose, the
commencement by a third party of a tender offer or exchange offer or similar
transaction other than a Hostile Tender Offer (as defined below) directly with
the Company's shareholders) (collectively, a "Third Party Deal") with a third
party which made an Acquisition Proposal at or prior to the time of such
termination, or (B) a tender offer or exchange offer or similar transaction
directly with the Company's shareholders for the acquisition of a majority of
the outstanding Ordinary Shares (or ADRs representing such majority) which has
been unilaterally commenced by a third party (a "Hostile Tender") which made an
Acquisition Proposal at or prior to the time of such termination shall have
become unconditional or irrevocable, or (2) within six months after such a
termination, if a third party made an Acquisition Proposal at or prior to the
time of such termination, and either (A) the Company shall enter into a Third
Party Deal with any other third party, or (B) a Hostile Tender commenced by any
other third party shall have become unconditional or irrevocable, or (y) this
Agreement is terminated pursuant to Section 8.1(d)(i) (if such termination
results from a breach of Section 6.6(b) hereof), or Section

                                      A-39
<PAGE>
8.1(b)(iv) or 8.1(d)(ii), then, in each case, the Company shall (in addition to
any obligation under Section 8.3(b) hereof and without prejudice to any other
rights that Buyer may have against the Company for a breach of this Agreement)
pay to Buyer U.S. $21,000,000 (the "TERMINATION FEE") in cash, such payment to
be made promptly, but in no event later than the second business day following,
in the case of clause (x), the later to occur of such termination and the entry
into of such Third Party Deal, or, in the case of clause (y), such termination.

    (d) Notwithstanding any provision in this Agreement to the contrary, if this
Agreement is terminated by the Company pursuant to Section 8.1(c) hereof, then
Buyer shall (without prejudice to any other rights the Company may have against
Buyer for breach of this Agreement), reimburse the Company upon demand for all
out-of-pocket fees and expenses incurred or paid by or on behalf of the Company
or any Affiliate of the Company in connection with this Agreement and the
transactions contemplated herein, including all fees and expenses of counsel,
investment banking firms, accountants and consultants, up to a maximum aggregate
amount of $1,500,000.

    (e) The parties acknowledge that the agreements contained in Sections
8.3(b), (c) and (d) hereof are an integral part of the transactions contemplated
by this Agreement, and that, without these agreements, Buyer, on the one hand,
and the Company, on the other, would not enter into this Agreement. Accordingly,
if the Company fails promptly to pay the amounts due pursuant to Sections 8.3(b)
and (c) hereof, or if Buyer fails promptly to pay the amounts due pursuant to
Section 8.3(d) hereof, (i) the party failing to so pay shall pay interest on
such amounts at the prime rate announced by U.S. Bank National Association,
Minneapolis office, in effect on the date the Termination Fee (or fees and
expenses) were required to be made, and (ii) if in order to obtain such payment
a party commences a suit or takes other action which results in a judgment or
other binding determination against the Company for the fees and expenses in
Sections 8.3(b) or 8.3(d) hereof or the Termination Fee, the nonpaying party
shall also pay to the party entitled to receive payment thereunder (as the case
may be) its costs and expenses (including reasonable attorneys' fees) in
connection with such suit, together with interest payable under the preceding
clause (i).

THE SCHEME

1.  CANCELLATION OF SCHEME SHARES

    (A) At the Effective Time, the share capital of Saville shall be reduced by
       the cancellation of the Scheme Shares and the holders of the Scheme
       Shares shall be allotted shares of ADC common stock in accordance with
       Clause 2(A).

    (B) Forthwith and contingently upon the reduction of capital referred to in
       sub-clause (A) taking effect:


        (i) the share capital of Saville shall be increased by $98,034.8775 and
            IRL30,000 by the creation of 39,213,951 new Saville ordinary shares
            and 30,000 new Saville deferred shares (together,


                                      B-3
<PAGE>

            the "New Shares"), such New Shares to confer the same respective
            rights and be subject to the same respective restrictions as the
            Scheme Shares of the same class; and


        (ii) Saville shall apply the requisite amount of the reserve arising as
             a result of such reduction of capital in paying up in full the New
             Shares created pursuant to Clause 1(B)(i), which shall be allotted
             and issued, and credited as fully paid, to ADC and/or its
             nominee(s).

2.  CONSIDERATION FOR THE CANCELLATION OF SCHEME SHARES


    (A) In consideration for the cancellation of the Scheme Shares, ADC shall,
       subject to Clause 4(C):


        (i) allot and issue new shares of ADC common stock credited as fully
            paid to and amongst the Relevant Holders of Scheme ordinary shares
            on the following basis (the "Ordinary Allotment Ratio"):

        for each Scheme Ordinary Share 0.358 of one share of ADC common stock;
    and

        (ii) allot and issue new shares of ADC common stock credited as fully
             paid to and amongst the Relevant Holders of Scheme deferred shares
             on the following basis (the "Deferred Allotment Ratio"):

        for each Scheme Deferred Share 0.027 of one share of ADC common stock;

           PROVIDED that no fractional shares of ADC common stock shall be
           issued to any such Relevant Holder of Scheme Shares and if, but for
           this provision, any such Relevant Holder would be entitled to a
           fractional share of ADC common stock, such fractional share of ADC
           common stock shall be rounded up to the next whole share of ADC
           common stock which shall be allotted and issued to such Relevant
           Holder.

    (B) If, between June 19, 1999 and the Effective Time, Saville ordinary
       shares shall be changed into a different number of shares or a different
       class of shares by reason of any reclassification, consolidation,
       division, subdivision or cancellation (other than the cancellation
       contemplated by Clause 1) or if a share dividend thereon shall be
       declared with a record date within such period (an "Ordinary Share
       Adjustment"), then the Ordinary Allotment Ratio shall be adjusted
       appropriately so as to maintain the proportional interests of the holders
       of Scheme ordinary shares in the outstanding shares of ADC common stock
       in effect immediately prior to the Ordinary Share Adjustment.

    (C) If, between June 19, 1999 and the Effective Time, Saville deferred
       shares shall be changed into a different number of shares or a different
       class of shares by reason of any reclassification, consolidation,
       division, subdivision or cancellation (other than the cancellation
       contemplated by Clause 1), or if a share dividend thereon shall be
       declared with a record date within such period (a "Deferred Share
       Adjustment"), then the Deferred Allotment Ratio shall be adjusted
       appropriately so as to maintain the proportional interests of the holders
       of Scheme deferred shares in the outstanding shares of ADC common stock
       in effect immediately prior to the Deferred Share Adjustment.

    (D) If, between June 19, 1999 and the Effective Time, shares of ADC common
       stock shall be changed into a different number of shares or a different
       class of shares by reason of any reclassification, recapitalization,
       split-up, combination, exchange of shares or readjustment, or if a stock
       dividend thereon shall be declared with a record date within such period,
       or if a cash dividend thereon of more than $1.00 per share of ADC common
       stock shall be declared with a record date within such period (a "common
       stock Adjustment"), then each of the Ordinary Allotment Ratio and the
       Deferred Allotment Ratio shall be adjusted appropriately so as to
       maintain the respective proportional interests of the holders of Scheme
       Shares in the outstanding ADC common stock in effect immediately prior to
       the common stock Adjustment.

                                      B-4

3.  ALLOTMENT AND ISSUE OF SHARES OF ADC COMMON STOCK

    (A) The shares of ADC common stock to be issued pursuant to Clause 2 shall
       rank PARI PASSU in all respects with all other shares of ADC common stock
       in issue on the Effective Date and shall rank for all dividends or
       distributions made, paid or declared on shares of ADC common stock
       following the Effective Date.

    (B) ADC shall issue to each Relevant Holder one or more certificates
       representing the shares of ADC common stock to be issued to such Relevant
       Holder pursuant to Clause 2 only upon surrender to ADC by such Relevant

    (C) No dividends or other distributions declared or made with respect to ADC
       common stock with a record date after the Effective Time shall be paid to

       shall surrender such certificate. Subject to the effect of attachment,
       tax or other applicable laws, following surrender of any such
       certificate, there shall be paid to the holder, without interest, (i) the

       at the appropriate payment date, the amount of dividends or other
       distributions, with a record date after the Effective Time but prior to
       surrender and a payment date occurring after surrender, payable with
       respect to the whole shares of ADC common stock which the holder was
       allotted pursuant to Clause 2.

    (D) If any certificate shall have been lost, stolen or destroyed, upon the
       making of an affidavit of that fact, in form and substance acceptable to
       ADC, by the person claiming such certificate to be lost, stolen or
       destroyed, and complying with such other conditions as ADC may reasonably
       impose (including the posting of an indemnity bond or other surety in
       favor of ADC with respect to the certificate alleged to be lost, stolen
       or destroyed), ADC will deliver to such person the number of shares of
       ADC common stock to which that person is entitled pursuant to Clause 2.

    (E) All deliveries of notices, documents of title and cheques required to be
       made by this Scheme shall be effected by posting the same in prepaid
       envelopes addressed to the persons respectively entitled thereto at their
       respective addresses as appearing in the relevant register of members
       (or, in the case of joint holders, to the address of that one of the
       joint holders whose name stands first in the said register of members in
       respect of the joint holding) immediately prior to the date of their
       despatch or to such other addresses (if any) as such persons may
       respectively direct in writing.

    (F) Neither Saville nor ADC shall be responsible for any loss or delay in
       the transmission of the documents of title or cheques posted in
       accordance with Clause 3(E), which shall be posted at the risk of the
       addressee.


    (G) As from the Effective Time, all certificates representing holdings of
       Scheme Shares shall cease to be valid for any purpose and each holder of
       Scheme Shares shall be bound on the request of Saville or ADC to deliver
       up to Saville or ADC, or to any person appointed by Saville or ADC to
       receive the same, for cancellation the certificate(s) for his/her Scheme
       Shares.


    (H) All shares of ADC common stock issued upon cancellation of the Scheme
       Shares in accordance with Clause 2 (including any cash paid pursuant to
       Clause 3(C)) shall be deemed to have been issued in full satisfaction of
       all rights pertaining to such Scheme Shares.

    (I) Neither ADC nor Saville shall be liable to any holder of Scheme Shares
       for any such shares of ADC common stock (or dividends or distributions
       with respect to such shares) or cash delivered to a public official in
       compliance with any law permitting attachment of money or property or
       similar law.

                           OPINION OF MORGAN STANLEY

June 18, 1999
Board of Directors
Saville Systems PLC
One Van de Graff DriveBurlington, MA 01803
Members of the Board:

We understand that Saville Systems PLC ("Saville" or the "Company") and ADC
Telecommunications, Inc. ("ADC") propose to enter into an agreement,
substantially in the form of the draft dated as of June 17, 1999 (the
"Agreement"), which provides, among other things, for a scheme of arrangement
(the "Scheme") in which all of the issued and outstanding ordinary shares,
nominal value $0.0025 per share (the "Saville ordinary shares"), of the Company
other than shares held by ADC or any subsidiary of ADC shall be canceled and the
holders thereof shall be allotted 0.358 (the "Ordinary Allotment Ratio") shares
of common stock, par value $0.20 per share, of ADC (the "ADC common stock") per
Saville Ordinary Share. The terms and conditions of the Scheme are more fully
set forth in the Agreement.

You have asked for our opinion as to whether the Ordinary Allotment Ratio
pursuant to the Agreement is fair from a financial point of view to the holders
of the Saville ordinary shares.

For purposes of the opinion set forth herein, we have, among other things:

    (i) reviewed certain publicly available financial statements and other
        business and financial information of Saville and ADC, respectively;

    (ii) reviewed certain internal financial statements and other financial and
         operating data concerning Saville and ADC prepared by the managements
         of Saville and ADC, respectively;

   (iii) discussed certain financial projections prepared by the managements of
         Saville and ADC, respectively;

    (iv) discussed the past and current operations and financial condition and
         the prospects of Saville, including information relating to certain
         strategic, financial and operational benefits anticipated from the
         Scheme, with senior executives of Saville;

    (v) discussed the past and current operations and financial condition and
        the prospects of ADC with senior executives of ADC;

    (vi) reviewed the pro forma impact of the Scheme on ADC's earnings per share
         and other financial ratios;

   (vii) reviewed the reported prices and trading activity for the American
         Depositary Receipts of Saville (the "Saville ADRs") representing
         American Depositary Shares of Saville, each representing one Saville
         Ordinary Share and the ADC common stock;

  (viii) discussed with the senior managements of Saville and ADC certain
         research analyst projections for Saville and ADC, respectively;

    (ix) compared the financial performance of Saville and ADC and the prices
         and trading activity of the Saville ADRs and the ADC common stock with
         that of certain other publicly-traded companies and their securities;

    (x) reviewed the financial terms, to the extent publicly available, of
        certain acquisition transactions deemed relevant;

                                      C-1
<PAGE>
    (xi) participated in discussions and negotiations among representatives of
         Saville and ADC and their financial and legal advisors;

   (xii) reviewed the Agreement and certain related documents; and

  (xiii) considered such other factors as Morgan Stanley deemed appropriate.

We have assumed and relied upon without independent verification the accuracy
and completeness of the information reviewed by us for the purposes of this
opinion. With respect to the internal financial statements and other financial
and operating data and discussions relating to strategic, financial and
operational benefits anticipated from the Scheme provided by Saville and ADC, we
have assumed that they have been reasonably prepared on bases reflecting the
best currently available estimates and judgements of the prospects of Saville
and ADC, respectively. We have relied upon the assessment by the managements of
Saville and ADC of their ability to retain key employees of Saville. We have
also relied upon, without independent verification, the assessment by the
managements of Saville and ADC of (i) the strategic and other benefits expected
to result from the Scheme, (ii) Saville's and ADC's technologies and products,
(iii) the timing and risks associated with the integration of Saville with ADC,
and (iv) the validity of, and risks associated with, Saville's and ADC's
existing and future products and technologies. We have not made any independent
valuation or appraisal of the assets or liabilities or technology of Saville or
ADC, nor have we been furnished with any such appraisals. In addition, we have
assumed that the Scheme will be accounted for as a "pooling-of-interests"
business combination in accordance with U.S. generally accepted accounting
principles and the Scheme will be treated as a tax-free reorganization and/or
exchange pursuant to the Internal Revenue Code of 1986 and will be consummated
in accordance with the terms set forth in the Agreement. Our opinion is
necessarily based on financial, economic, market and other conditions as in
effect on, and the information made available to us as of, the date hereof.

We have acted as financial advisor to the Board of Directors of the Company in
connection with this transaction and will receive a fee for our services. In the
ordinary course of our business we may actively trade the securities of Saville
and ADC for our own account and for the accounts of our customers and,
accordingly, may at any time hold a long or short position in such securities.

It is understood that this letter is for the information of the Board of
Directors of the Company and may not be used for any other purpose without our
prior written consent, except that this opinion may be included in its entirety
in any filing made by the Company with the Securities and Exchange Commission or
the High Court of Ireland in respect of the transaction. In addition, this
opinion does not in any manner address the prices at which the Saville ADRs or
the ADC common stock will actually trade at any time and we express no
recommendation or opinion as to how the holders of the Saville ordinary shares
should vote at the shareholders' meeting held in connection with the Scheme.

    Based upon and subject to the foregoing, we are of the opinion on the date
hereof that the Ordinary Allotment Ratio as set forth in the Agreement is fair
from a financial point of view to the holders of the Saville ordinary shares.

                                Very truly yours,
                                MORGAN STANLEY & CO. INCORPORATED

and agreements set forth herein and in the Acquisition Agreement, the parties
hereto agree as follows:

    1. DEFINED TERMS.  Capitalized terms which are used but not defined herein
shall have the meanings ascribed to them in the Acquisition Agreement.

    2. THE OPTION; EXERCISE; ADJUSTMENTS.

    (a) The Company hereby grants to Optionee an irrevocable option (the
"OPTION") to purchase from time to time up to 7,799,805 authorized and unissued
Ordinary Shares, nominal value $.0025 per share, of the Company (the "COMPANY
ORDINARY SHARES") (which shall be evidenced by ADRs) upon the terms and subject
to the conditions set forth herein (the "OPTIONED SHARES," which represent 19.9%
of the issued and outstanding Company Ordinary Shares as of the date hereof).

    (b) Subject to the terms and conditions set forth in this Agreement, the
Option may be exercised by Optionee in whole or, from time to time, in part, at
any time after the date hereof that the conditions in Section 3(a) hereof are
satisfied and prior to the termination of the Option in accordance with Section
12 hereof. In the event Optionee wishes to exercise the Option, Optionee shall
send a written notice to the Company (the "STOCK EXERCISE NOTICE") specifying
the total number of Optioned Shares it wishes to purchase and a date for the
closing of such purchase (the "CLOSING DATE"). Optionee may revoke an exercise
of the Option at any time prior to the Closing Date by written notice to the
Company. At any Closing Date, the Company will deliver to Optionee a certificate
or certificates representing the Optioned Shares in the denominations designated
by Optionee in its Stock Exercise Notice, free and clear of all liens and
encumbrances and subject to no preemptive rights, as well as an executed new
agreement with the same terms as this Agreement evidencing the right to purchase
the balance of the Optioned Shares purchasable hereunder, if any. After payment
of the Exercise Price for the Optioned Shares covered by the Stock Exercise
Notice, the Option shall be deemed exercised to the extent of the Optioned
Shares specified in the Stock Exercise Notice as of the date such Stock Exercise
Notice is given to the Company.

    (c) In the event of any change in the number of issued and outstanding
Company Ordinary Shares by reason of any share dividend, reclassification,
consolidation, division, subdivision or cancellation or other change in the
corporate or capital structure of the Company, the number of Optioned Shares
subject to the

                                      D-1
<PAGE>
Option and the Exercise Price (as hereinafter defined) per Optioned Share shall
be appropriately adjusted. In the event that any additional Company Ordinary
Shares are issued after the date of this Agreement (other than pursuant to an
event described in the preceding sentence or pursuant to this Agreement), the
number of Optioned Shares subject to the Option shall be adjusted so that, after
such issuance, it equals at least 19.9% of the number of Company Ordinary Shares
then issued and outstanding (without considering any shares subject to the
Option).

    3. CONDITIONS TO EXERCISE OF OPTION AND DELIVERY OF OPTIONED SHARES.

    (a) Optionee's right to exercise the Option is subject to the following
conditions:

        (i) No preliminary or permanent injunction or other order having been
    issued by any federal or state court of competent jurisdiction in the United

    as amended (the "EXCHANGE ACT")), acquires or becomes the beneficial owner
    of 20% or more of the outstanding Company Ordinary Shares; (B) any new group

    than Optionee or its affiliates) shall have commenced a tender or exchange

    other similar business combination involving the Company; (D) any Person
    (other than Optionee or its affiliates) is granted any option or right,

    Shares beneficially owned by such Person, results or would result in such
    Person being the beneficial owner of 20% or more of the outstanding Company
    Ordinary Shares; or (E) any event or circumstance occurs that would entitle
    Optionee to receive the Termination Fee provided for in Section 8.3(c) of
    the Acquisition Agreement. For purposes of this subparagraph (iii), the
    terms "group" and "beneficial owner" shall be defined by reference to
    Section 13(d) of the Exchange Act.

exercise of the Option, and the Company's obligation to deliver the Optioned
Shares, are subject to the conditions that:

    Republic of Ireland prohibiting the delivery of the Optioned Shares shall be
    in effect;

        (ii) The purchase of the Optioned Shares will not violate Rule 10b-13
    promulgated under the Exchange Act;

in immediately available funds.

and warrants to Optionee as follows:

contemplated. This Agreement has been duly executed and delivered by the Company
and constitutes a valid and binding obligation of the Company enforceable
against the Company in accordance with its terms except to the extent that its
enforceability may be limited to applicable bankruptcy, insolvency, fraudulent
transfer, reorganization, moratorium or other laws affecting creditors' rights
generally and to general equitable principles.

    (b) SHARES RESERVED FOR ISSUANCE. The Company has taken all necessary
corporate action to authorize and reserve and permit it to issue, and at all
times from the date hereof through the termination of this Agreement in
accordance with its terms, will have reserved for issuance upon exercise of this
Option, that number of Optioned Shares equal to the maximum number of Company
Ordinary Shares at any time and from time to time purchasable upon exercise of
the Option, and the Optioned Shares, when issued and delivered by the Company to
Optionee upon exercise of the Option, will be duly authorized, validly issued,
fully paid and nonassessable, free and clear of all liens or encumbrances, free
of preemptive rights, and the ADRs evidencing such Company Ordinary Shares shall
be listed on the Nasdaq National Market.

    (c) CONSENTS; NO VIOLATIONS. Except as otherwise required by the HSR Act,

of this Agreement by the Company and the consummation by it of the transactions
contemplated hereby do not and will not require the consent, approval or
authorization of, or filing with, any Person or public authority and (i) will
not violate, breach or conflict with the Company's Articles or Memorandum of
Association or (ii) result in the acceleration or termination of, or constitute

regulation, judgment, order or other restriction binding upon or applicable to
the Company or any of its subsidiaries or any of their respective properties or
assets, except, with respect to clause (ii) hereof, for any acceleration,

reasonably be expected to have a Company Material Adverse Effect.

    6. REPRESENTATIONS AND WARRANTIES OF OPTIONEE.  Optionee represents and
warrants to the Company as follows:

    (a) CORPORATE AUTHORITY. The execution and delivery of this Agreement by
Optionee and the consummation by it of the transactions contemplated hereby have
been duly authorized by all necessary corporate action on the part of Optionee
and this Agreement has been duly executed and delivered by Optionee and
constitutes a valid and binding agreement of Optionee, except to the extent that
its enforceability may be limited to applicable bankruptcy, insolvency,
fraudulent transfer, reorganization, moratorium or other laws affecting
creditors' rights generally and to general equitable principles.

    (b) INVESTMENT REPRESENTATIONS. Optionee is acquiring the Option and, if and
when it exercises the Option, will be acquiring the Optioned Shares issuable
upon the exercise thereof, for its own account and not with a view to
distribution or resale in any manner which would be in violation of the
Securities Act of 1933, as amended (the "SECURITIES ACT"), or any rule or
regulation under the Securities Act, and will not sell

                                      D-3
<PAGE>
or otherwise dispose of the Optioned Shares except pursuant to an effective
registration statement under the Securities Act or a valid exemption from
registration under the Securities Act.

    7. THE CLOSING.  Any closing hereunder shall take place on the Closing Date
specified by Optionee in its Stock Exercise Notice pursuant to Section 2 at
10:00 a.m., U.S. Eastern Time, or the first business day thereafter on which all
of the conditions in Section 3 are met, at the executive office of the Company
located in Burlington, Massachusetts, or at such other time and place as the
parties hereto may agree.

    8. FILINGS RELATED TO OPTIONED SHARES.  The Company will make such filings
with the SEC as are required by the Exchange Act, and will make all necessary
filings by the Company under the HSR Act and the Irish Control Act and to list
the Optioned Shares (as evidenced by ADRs) on the Nasdaq National Market.

    9. REGISTRATION RIGHTS.

    (a) DEMAND REGISTRATION RIGHTS. The Company shall, subject to the conditions
of Section 9(c) below, if requested by Optionee, or any permitted transferee
acquiring at least 10% of the Company Ordinary Shares represented by the Option
on the date hereof (each, a "SELLING SHAREHOLDER"), as expeditiously as possible
prepare and file a registration statement under the Securities Act if such
registration is necessary in order to permit the sale or other disposition of
any or all Company Ordinary Shares or other securities that have been acquired
by or are issuable to the Selling Shareholder upon exercise of the Option in
accordance, subject to the terms and conditions of this Section 9, with the
intended method of sale or other disposition stated by the Selling Shareholder
in such request, including without limitation a "shelf" registration statement
under Rule 415 under the Securities Act or any successor provision ("RULE 415"),
and the Company shall use its best efforts to qualify such shares or other
securities for sale under any applicable state securities laws; PROVIDED,
HOWEVER, that the Company shall not be required to consent to general
jurisdiction or qualify to do business in any state where it is not otherwise
required to so consent to such jurisdiction or to so qualify to do business.

    (b) ADDITIONAL REGISTRATION RIGHTS. If the Company, at any time after the
exercise of the Option, proposes to register any securities of the Company or
rights representing securities of the Company under the Securities Act, the
Company will promptly give written notice to the Selling Shareholders of its
intention to do so and, upon the written request of any Selling Shareholder
given within thirty (30) days after receipt of any such notice (which request
shall specify the number of Company Ordinary Shares intended to be included in
such public offering by the Selling Shareholder), the Company will cause all
such shares for which a Selling Shareholder requests participation in such
registration, to be so registered and included in such public offering;
PROVIDED, HOWEVER, that the Company may elect not to cause any such shares to be
so registered (i) if such public offering is to be underwritten and the
underwriters in good faith object for valid business reasons, or (ii) in the
case of a registration solely to implement an employee benefit plan or a
registration filed on Form S-4 of the Securities Act or any successor Form;
PROVIDED, FURTHER, HOWEVER, that such election pursuant to (i) may only be made
twice. If some but not all of the Company Ordinary Shares with respect to which
the Company shall have received requests for registration pursuant to this
Section 9(b) shall be excluded from such registration, the Company shall make
appropriate allocation of shares to be registered among the Selling Shareholders
desiring to register their shares pro rata in the proportion that the number of
shares requested to be registered by each such Selling Shareholder bears to the
total number of shares requested to be registered by all such Selling
Shareholders then desiring to have Company Ordinary Shares registered for sale.

    (c) CONDITIONS TO REQUIRED REGISTRATION. The Company shall use all
reasonable efforts to cause each registration statement referred to in Section
9(a) above to become effective and to obtain all consents or waivers of other
parties which are required therefor and to keep such registration effective;
PROVIDED, HOWEVER, that the Company may delay any registration of Option Shares
required pursuant to Section 9(a) above for a period not exceeding seventy-five
(75) days PROVIDED the Company shall in good faith

                                      D-4
<PAGE>
determine that any such registration would adversely affect the Company
(provided that this right may not be exercised more than once during any twelve
(12) month period), and the Company shall not be required to register Option
Shares under the Securities Act pursuant to Section 9(a) above:

        (i) on more than one occasion during any calendar year;

        (ii) on more than two occasions in total;

        (iii) within ninety (90) days after the effective date of a registration
    referred to in Section 9(b) above pursuant to which the Selling Shareholder
    or Selling Shareholders concerned were afforded the opportunity to register
    such shares under the Securities Act and such shares were registered as
    requested;

        (iv) unless a request therefor is made to the Company by Selling
    Shareholders that hold at least 25% or more of the aggregate number of
    Option Shares

           (including Company Ordinary Shares issuable upon exercise of this
           Option) then outstanding; or

        (v) if all the Option Shares proposed to be registered could be sold by
    the Selling Shareholders in a ninety (90) day period in accordance with Rule
    144.

    In addition to the foregoing, the Company shall not be required to maintain
the effectiveness of any registration statement, other than a registration
statement filed under Rule 415, after the expiration of six (6) months from the
effective date of such registration statement. The Company shall use all
reasonable efforts to make any filings, and take all steps, under all applicable
state securities laws to the extent necessary to permit the sale or other
disposition of the Option Shares so registered in accordance with the intended
method of distribution for such shares; PROVIDED, HOWEVER, that the Company
shall not be required to consent to general jurisdiction or qualify to do
business in any state where it is not otherwise required to so consent to such
jurisdiction or to so qualify to do business.

    (d) EXPENSES. Except where applicable state law prohibits such payments, the
Company will pay all expenses (including without limitation registration fees,
qualification fees, blue sky fees and expenses (including the fees and expenses
of counsel), legal expenses, including the reasonable fees and expenses of one
counsel to the holders whose Option Shares are being registered, printing
expenses and the costs of special audits or "cold comfort" letters, expenses of
underwriters, excluding discounts and commissions but including liability
insurance if the Company so desires or the underwriters so require, and the
reasonable fees and expenses of any necessary special experts) in connection
with each registration pursuant to Section 9(a) or 9(b) above (including the
related offerings and sales by holders of Option Shares) and all other
qualifications, notifications or exemptions pursuant to Section 9(a) or 9(b)
above.

    (e) INDEMNIFICATION. In connection with any registration under Section 9(a)
or 9(b) above, the Company hereby indemnifies the Selling Shareholders, and each
underwriter thereof, including each person, if any, who controls such Optionee
or underwriter within the meaning of Section 15 of the Securities Act, against
all expenses, losses, claims, damages and liabilities caused by any untrue, or
alleged untrue, statement of a material fact contained in any registration
statement or prospectus or notification or offering circular (including any
amendments or supplements thereto) or any preliminary prospectus, or caused by
any omission, or alleged omission, to state therein a material fact required to
be stated therein or necessary to make the statements therein not misleading,
except insofar as such expenses, losses, claims, damages or liabilities of such
indemnified party are caused by any untrue statement or prospectus or
notification or offering circular (including any amendments or supplements
thereto) in reliance upon and in conformity with, information furnished in
writing to the Company by such indemnified party expressly for use therein, and
the Company and each officer, director and controlling person of the Company
shall be indemnified by such Selling Shareholders, or by such underwriter, as
the case may be, for all such expenses, losses, claims, damages and liabilities
caused by any untrue, or alleged untrue, statement, that

                                      D-5
<PAGE>
was included by the Company in any such registration statement or prospectus or
notification or offering circular (including any amendments or supplements
thereto) in reliance upon, and in conformity with, information furnished in
writing to the Company by or on behalf of such Selling Shareholder or such
underwriter, as the case may be, expressly for such use.

    Promptly upon receipt by a party indemnified under this Section 9(e) of
notice of the commencement of any action against such indemnified party in
respect of which indemnity or reimbursement may be sought against any
indemnifying party under this Section 9(e), such indemnified party shall notify
the indemnifying party in writing of the commencement of such action, but the
failure so to notify the indemnifying party shall not relieve it or any
liability which it may otherwise have to any indemnified party under this
Section 9(e) except to the extent the indemnified party is materially prejudiced
thereby. In case notice of commencement of any such action shall be given to the
indemnifying party as above PROVIDED, the indemnifying party shall be entitled
to participate in and, to the extent it may wish, jointly with any other
indemnifying party similarly notified, to assume the defense of such action at
its own expense, with counsel chosen by it and reasonably satisfactory to such
indemnified party. The indemnified party shall have the right to employ separate
counsel (other than reasonable costs of investigation) shall be paid by the
indemnified party unless (i) the indemnified party either agrees to pay the
same, (ii) the indemnifying party fails to assume the defense of such action
with counsel reasonably satisfactory to the indemnified party, or (iii) the
indemnified party has been advised by counsel that one or more legal defenses
may be available to the indemnifying party that may be contrary to the interest
of the indemnified party, in which case the indemnifying party shall be entitled
to assume the defense of such action notwithstanding its obligation to bear fees
and expenses of such counsel. No indemnifying party shall be liable for any
settlement entered into without its consent, which consent may not be
unreasonably withheld.

    If the indemnification provided for in this Section 9(e) is unavailable to a
party otherwise entitled to be indemnified in respect of any expenses, losses,
claims, damages or liabilities referred to herein, then the indemnifying party,
in lieu of indemnifying such party otherwise entitled to be indemnified, shall
contribute to the amount paid or payable by such party to be indemnified as a
result of such expenses, losses, claims, damages or liabilities in such
proportion as is appropriate to reflect the relative benefits received by the
Company, the Selling Shareholders and the underwriters from the offering of the
securities and also the relative fault of the Company, the Selling Shareholders
and the underwriters in connection with the statements or omissions which
resulted in such expenses, losses, claims, damages or liabilities, as well as
any other relevant equitable considerations. The amount paid or payable by a
party as a result of the expenses, losses, claims, damages and liabilities
referred to above shall be deemed to include any legal or other fees or expenses
reasonably incurred by such party in connection with investigating or defending
any action or claim; PROVIDED, HOWEVER, that in no case shall any Selling
Shareholder be responsible, in the aggregate, for any amount in excess of the
net offering proceeds attributable to its Option Shares included in the
offering. No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Securities Act) shall be entitled to contribution from
any person who was not guilty of such fraudulent misrepresentation.

    Any obligation by any Selling Shareholder to contribute shall be several and
not joint with other holders.

    In connection with any registration pursuant to Section 9(a) or 9(b) above,
the Company and each Selling Shareholder (other than Optionee) shall enter into
an agreement containing the indemnification provisions of this Section 9(e). In
the event of an underwritten public offering pursuant to Section 9(b), the
Company and the Selling Shareholders shall enter into an underwriting agreement
containing customary terms and provisions; PROVIDED that the contribution
provisions as they relate to Selling Shareholders shall contain substantially
the same limitations as the provisions set forth herein.

    (f) MISCELLANEOUS REPORTING. The Company shall comply with all reporting
requirements and will do all other such things as may be necessary to permit the
expeditious sale at any time of any Option Shares by

                                      D-6
<PAGE>
the Selling Shareholders thereof in accordance with and to the extent permitted
by any rule or regulation promulgated by the SEC from time to time, including,
without limitation, Rule 144. The Company shall at its expense provide the
Selling Shareholders with any information necessary in connection with the
completion and filing of any reports or forms required to be filed by them under
the Securities Act or the Exchange Act, or required pursuant to any state
securities laws or the rules of any stock exchange.

    (g) ISSUE TAXES. The Company will pay all stamp taxes in connection with the
issuance and the sale of Option Shares and in connection with the exercise of
the Option, and will hold the Selling Shareholders harmless, without limitation
as to time, against any and all liabilities, with respect to all such taxes.

    10. OPTIONAL PUT.  Prior to the termination of the Option in accordance with
Section 12 hereof, if the Option has become exercisable pursuant to Section 2(b)
hereof and pursuant to the second sentence of this Section 10, Optionee shall
have the right, upon three (3) business days' prior written notice to the
Company, to require the Company to purchase the Option from Optionee (the "PUT
RIGHT") at a cash purchase price (the "PUT PRICE") equal to the product
determined by multiplying (A) the number of Optioned Shares as to which the
Option has not yet been exercised by (B) the Spread (as defined below). As used
herein, the term "SPREAD" shall mean the excess, if any, of (i) the greater of
(x) the highest price (in cash or fair market value of securities or other
property) per Company Ordinary Share (whether or not evidenced by ADRs) paid or
to be paid within twelve (12) months preceding the date of exercise of the Put
Right for any Company Ordinary Shares (whether or not evidenced by ADRs)
beneficially owned by any Person who shall have acquired or become the
beneficial owner of 20% or more of the outstanding Company Ordinary Shares
(whether or not evidenced by ADRs) after the date hereof or (y) the weighted (by
volume of shares represented by ADRs traded each day during the measurement
period described herein) average closing price of the Company Ordinary Shares
(evidenced by ADRs) during the 15-day period ending on the trading day
immediately preceding the written notice of exercise of the Put Right over (ii)
the Exercise Price. This Put Right shall become exercisable with respect to the
events described in clauses (A), (B), (C) and (D) of Section 3(a)(ii) hereof
only if the beneficial ownership by the Person or group referenced in such
clauses equals or exceeds 30% of the outstanding Company Ordinary Shares. Upon
exercise of Optionee's right to receive cash pursuant to this Section 10, the
obligation of the Company to deliver Optioned Shares pursuant to this Agreement
shall terminate with respect to such number of Optioned Shares for which
Optionee shall have elected to be paid in cash under this Section 10.

                                      D-7
<PAGE>
    11. PROFIT LIMITATION.

    (a) Notwithstanding any other provision of this Agreement, in no event shall
Optionee's Total Profit (as hereinafter defined) exceed $21 million and, if it
otherwise would exceed such amount, Optionee, at its sole election, shall either
(i) deliver to the Company for cancellation Optioned Shares previously acquired
by Optionee pursuant to this Agreement, (ii) pay cash or other consideration to
the Company, or (iii) undertake any combination thereof, in each case, so that
Optionee's Total Profit shall not exceed $21 million after taking into account
the foregoing actions.

    (b) As used herein, the term "Total Profit" shall mean the sum (before
taxes) of the following: (i) the amount of cash received by Optionee pursuant to
Section 10 hereof, (ii)(A) the net cash amounts received by Optionee pursuant to
the sale of Optioned Shares (or any other securities into which such Optioned
Shares are converted or exchanged) to any unaffiliated party, less (B) the
aggregate Exercise Price paid for all Optioned Shares acquired by Optionee
hereunder, and (iii) any Termination Fee received pursuant to the Acquisition
Agreement.

    12. TERMINATION.  This Agreement and the Option shall terminate upon the
earlier of (i) the Effective Time (as defined in the Acquisition Agreement) and
(ii) the termination of the Acquisition Agreement in accordance with its terms;
PROVIDED, HOWEVER, the Option shall not terminate pursuant to clause (ii)
immediately above if (A) the Acquisition Agreement is terminated by Optionee
pursuant to Section 8.1(d)(i) or (d)(ii) thereof or (B) the Acquisition
Agreement is terminated by Optionee or the Company pursuant to Section
8.1(b)(ii) or (b)(iv) thereof and, in each such case, the Company has not paid
to Optionee the Termination Fee which the Company is then obligated to pay.

    13. EXPENSES.  Each party hereto shall pay its own expenses incurred in
connection with this Agreement, except as otherwise provided in Section 9 hereof
or as specified in the Acquisition Agreement.

    14. SPECIFIC PERFORMANCE.  The parties hereto agree that irreparable damage
would occur in the event that any of the provisions of this Agreement were not
performed in accordance with their specific terms or were otherwise breached. It
is accordingly agreed that the parties shall be entitled to an injunction or
injunctions to prevent breaches of this Agreement, without the necessity of
proving damages or posting any bond, and to enforce specifically the terms and
provisions hereof in any court of the Republic of Ireland or the United States
or any state thereof having jurisdiction, this being in addition to any other
remedy to which they are entitled at law or in equity.

    15. NOTICE.  All notices, requests, demands and other communications
hereunder shall be deemed to have been duly given and made if in writing and if
