                              TRANSACTION AGREEMENT

            This TRANSACTION AGREEMENT (this "Agreement") dated as of May 4,
2000 is entered into by Galen Holdings PLC, a Northern Ireland public limited
company ("Galen"), and Warner Chilcott, PLC, an Irish public limited company
("Warner").

            WHEREAS, the respective Boards of Directors of Galen and Warner have
approved the combination of the businesses of Galen and Warner on the terms and
subject to the conditions set forth in this Agreement and the Scheme; and

            WHEREAS, Galen has received executed Employment Agreements in form
and substance satisfactory to Galen;

            WHEREAS, such combination is proposed to be effected, subject to the
sanction of the High Court of Ireland (the "Court"), by means of a scheme of
arrangement in substantially the form attached hereto as Exhibit A (the
"Scheme") under Section 201 of the Companies Act, 1963, of Ireland (the "Irish
Companies Act"), whereby (i) all of the ordinary shares of US$0.05 each in the
capital of Warner ("Warner Shares"), excluding any Warner Shares held by or on
behalf of Galen or any Subsidiary of Galen (as more particularly described in
the Scheme, "Scheme Shares"), will be cancelled in consideration for the issue
to the holders of Scheme Shares of a number of new ordinary shares of 10p each
in the capital of Galen ("Galen Shares") determined as set forth herein and (ii)
the reserve arising on cancellation of the Scheme Shares will be applied to pay
up in full an issue of new shares in Warner to Galen, such that Warner will
become a wholly-owned subsidiary of Galen; and it is proposed that, in
conjunction with the Scheme, certain amendments will be made to the Articles of
Association of Warner (the "Amendments") so as to ensure that any Warner Shares
issued after the Effective Time (as defined in the Scheme) other than to Galen
or its nominee will be exchanged for Galen Shares on the same basis as under the
Scheme, and that arrangements will be made under which Options (as defined
herein) may be converted into options to acquire Galen Shares upon the terms and
subject to the conditions set forth herein and in accordance with the relevant
laws;

            WHEREAS, Warner has previously (i) deposited Warner Shares with The
Bank of New York (the "Depositary") and (ii) caused the Depositary to issue
American Depositary Shares, each representing one Warner Share (the "Warner
ADS's") in respect thereof; and

            WHEREAS, Galen intends to (i) deposit Galen Shares with the
Depositary and (ii) cause the Depositary to issue American Depositary Shares
(the "Galen ADSs") in respect thereof; and

            WHEREAS, under the terms of the Scheme, holders of Scheme Shares
(including the Scheme Shares represented by the Warner ADSs) will receive 2.5
Galen Shares for each Warner Share subject to adjustment as provided by the
Scheme (as more particularly defined in the Scheme the "Per Share
Consideration"); and

            WHEREAS, the parties intend to enter into arrangements whereby
holders of


                                       1
<PAGE>   4
Warner ADSs representing Scheme Shares will receive Galen ADSs in respect of the
Per Share Consideration for such Scheme Shares; and

            WHEREAS, the Boards of Directors of Galen and Warner have approved
the acquisition of Warner by Galen pursuant to the Scheme (the "Acquisition")
and the other transactions contemplated hereby (collectively the
"Transactions"), in accordance with the laws of Ireland ("Irish Law") and upon
the terms and subject to the conditions set forth in this Agreement; and

            WHEREAS under the terms of the Scheme all the issued Deferred Shares
in the capital of Warner will be cancelled in consideration of the issue of one
new Galen Share; and

            WHEREAS, concurrently with the execution of this Agreement and as an
inducement to Warner to enter into this Agreement, certain shareholders of Galen
have entered into shareholder agreements (each, a "Galen Shareholder Agreement")
in the form attached hereto as Annex A, pursuant to which, among other things,
such shareholders have agreed, pursuant to the terms thereof, to support, and
vote their Galen Shares in favor of, the Transactions; and

            WHEREAS, Galen and Warner desire to make certain representations,
warranties, covenants and agreements in connection with the Transactions and
also to prescribe various conditions to the implementation of the Scheme set
forth herein; and

            WHEREAS, for U.S. federal income tax purposes, the parties expect
that the Transactions will qualify as a reorganization within the meaning of
Section 368(a)(1)(B) of the U.S. Internal Revenue Code of 1986, as amended (the
"Code"); and

            WHEREAS, certain capitalized terms used in this Agreement have the
meaning as set forth or referred to in Article X hereof.

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

               ARTICLE I -- THE ACQUISITION, INCLUDING THE SCHEME

            SECTION 1.01 Implementation of the Scheme.

                  (a) Warner and Galen shall take all such steps and actions
reasonably within their respective powers and shall prepare, execute, agree,
settle, publish and/or announce (and use their reasonable best efforts to
procure to be prepared, executed, agreed, settled, published and announced), all
such documents as may be necessary or appropriate for the implementation of the
Scheme and the Transactions in accordance with the terms and conditions of this
Agreement and the requirements of applicable law, the United States Securities
and Exchange Commission ("SEC"), the UK Listing Authority (as hereinafter
defined), the London


                                       2
<PAGE>   5
Stock Exchange ("LSE"), the Nasdaq National Market ("Nasdaq") and the Court. The
parties shall respectively use their reasonable best efforts to cause the
Effective Date (as defined in the Scheme) to occur on or before August 31, 2000.
Notwithstanding the foregoing, if the Effective Date does not occur on or before
August 31, 2000, the parties shall use their respective reasonable 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.

                  (b) (i) As promptly as practicable after the date of this
Agreement, Warner shall prepare a Proxy Statement (the "Proxy Statement")
complying with all requirements of applicable law, the Court and the SEC and
without limitation containing:

                              (1) the text of the Scheme;

                              (2) an explanatory statement in relation to the
                        Scheme as required by Irish Law;

                              (3) a notice convening a meeting or meetings of
                        holders of Warner Shares pursuant to an order of the
                        Court for the purpose of voting on the Scheme (such
                        meetings, including any adjournment thereof, being the
                        "Court Meeting");

                              (4) a notice convening an extraordinary general
                        meeting of Warner for the purpose of voting on a Special
                        Resolution ("the Warner EGM Resolution") to approve the
                        reduction and cancellation of capital of Warner (the
                        "Capital Reduction") and creation and issue of new
                        Warner Shares to Galen contemplated by the Scheme and
                        the Amendments (such meeting, including any adjournment
                        thereof, being the "Warner EGM");

                              (5) such other information as may be required by
                        the SEC, Nasdaq, the Court or applicable law.

                        (ii) Warner shall give Galen and its advisers all
                  reasonable opportunity to review and comment on drafts of and
                  approve the final forms of drafts, and final forms of all
                  documents to be filed with the Court, including those
                  documents referred to in paragraph (b)(i) of this Section
                  1.01, prior to the filing thereof by Warner (such approval not
                  to be unreasonably withheld or delayed) and will duly take
                  account of any comments thereon made by Galen and its
                  advisers. Warner shall consult with Galen regarding the
                  conduct of all court proceedings and shall advise Galen's
                  counsel of the dates of any hearings.

                  (c) Galen shall be represented in the Court by solicitors or
counsel on


                                       3
<PAGE>   6
the hearing of the Petition and any other hearings, and shall give such
undertakings, subject to the Scheme becoming effective, as are required by the
Court for the purposes of assuring the Court that Galen shall perform those acts
which the Scheme provides that it shall perform.

                  (d) The Proxy Statement will set forth, and Warner hereby
represents, that the Board of Directors of Warner (the "Warner Board") at a
meeting duly called and held, has (i) determined that the Scheme is fair to and
in the best interests of Warner and Warner Shareholders; and (ii) recommended
approval by Warner Shareholders of the Scheme and the Warner EGM Resolution
(such recommendation to the Warner Shareholders being referred to as the "Warner
Board Recommendation" and references to the Warner Board Recommendation herein
to include, where the context so allows, a recommendation against any proposed
adjournment of the Court Meeting or the Warner EGM other than due to practical
difficulties); provided, however, that the Warner Board recommendation may be
withdrawn, modified or amended to the extent that the Warner Board determines in
good faith, after taking due account of advice from its outside counsel as to
legal matters and from its independent financial adviser as to financial
matters, that its fiduciary duties would be likely to require it to do so.
Warner further represents that Credit Suisse First Boston Corporation ("CSFB")
has delivered to the Warner Board its written opinion to the effect that, as of
the date thereof, the Per Share Consideration to be offered to the holders of
Warner Shares and Warner ADSs (other than Galen and its affiliates) pursuant to
the Scheme is fair to such holders from a financial point of view.

                  (e) On the terms and subject to the conditions of this
Agreement, Warner shall promptly take or cause to be taken such steps as are
within its power and necessary or reasonably required to implement the Scheme,
including the following:

                        (i) Warner shall issue proceedings requesting the Court
                  to order that the Court Meeting be convened;

                        (ii) upon the giving by the Court of any directions in
                  that respect, and the Proxy Statement and related forms of
                  proxy for use at the Court Meeting and the Warner EGM being
                  approved (to the extent required) by the Court, Warner shall,
                  in accordance with the directions of the Court, promptly
                  dispatch the Proxy Statement and proxy forms to the Warner
                  Shareholders and thereafter publish and/or post the requisite
                  advertisements and such other documents and information as the
                  Court may approve or direct from time to time in connection
                  with the implementation of the Scheme in accordance with
                  applicable law;

                        (iii) (subject to the attendance of a quorum) Warner
                  shall hold the Court Meeting and the Warner EGM and, provided
                  the necessary resolutions are duly passed at such meetings (by
                  the requisite votes required under Section 201(3) of the Irish
                  Companies Act ("Section 201"), in the case of the Court
                  Meeting) promptly after such vote has been taken present a
                  petition or petitions (the "Petition") and issue a notice of
                  motion


                                       4
<PAGE>   7
                  for directions and file any grounding affidavits required
                  requesting the Court to issue directions in relation to the
                  date to be fixed for the hearing of the Petition and for an
                  order of the Court directing the manner of advertisement of
                  the hearing of the Petition and for such further and other
                  orders as the Court deems fit. Warner shall as soon as
                  practicable thereafter proceed with the Petition for the
                  purpose of obtaining an order or orders of the Court (the
                  "Final Court Order") sanctioning the Scheme and confirming the
                  Capital Reduction; and

                        (iv) within three business days after the perfection of
                  the Final Court Order, Warner shall cause a copy of the Final
                  Court Order and the minute required by Section 75 of the Irish
                  Companies Act to be duly delivered to the Registrar of
                  Companies in Ireland and obtain from such Registrar a
                  certificate of registration in relation to the Capital
                  Reduction.

                  (f) Warner hereby represents and warrants to Galen that the
Proxy Statement will comply in all material respects with the provisions of
applicable federal securities laws, and on the date filed with the SEC, on the
date first published, sent or given to Warner's stockholders and on the date of
the Warner EGM, shall not contain any untrue statement of a material fact or
omit to state any material fact required to be stated therein or necessary in
order to make the statements made therein, in light of the circumstances under
which they were made, not misleading (provided that for the purposes of this
Agreement Warner makes no representation or warranty with respect to any
information concerning Galen and its Subsidiaries supplied by Galen for
inclusion in the Proxy Statement). Warner and Galen agree promptly to correct
any information provided by either of them for use in the Proxy Statement if and
to the extent that it shall have become false or misleading, and Warner further
agrees to take all steps necessary to cause the Proxy Statement as so corrected
to be filed with the SEC and to be disseminated to the holders of the Warner
Shares, in each case, as and to the extent required by applicable federal
securities law.

                  (g) As promptly as practicable after the date hereof, Galen
and Warner shall prepare and file with the SEC (i) either a "no action" request
letter seeking an exemption from the registration requirements of the Securities
Act with respect to Galen Shares to be issued under the Scheme or (ii) at
Galen's discretion or in the event that a "no action" request letter is denied
or withdrawn a registration statement meeting, in all material respects, the
requirements of Form F-4 under the Securities Act, in which the Proxy Statement
will be included as part of a proxy statement/prospectus (in substantially the
form mailed to Warner's shareholders, the "PS/P") and in either case any other
documents required or mutually agreed by Galen and Warner to be necessary to
discharge their respective obligations under United States and Irish securities
laws, in connection with the Transactions. Galen hereby represents and warrants
that the PS/P shall not include any untrue statement (provided that for the
purposes of this Agreement Galen makes no representation or warranty with
respect to any information concerning Warner and its subsidiaries supplied by
Warner) of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements made therein, in light of the


                                       5
<PAGE>   8
circumstances under which they are made, not misleading. The written statements
supplied by Warner specifically for inclusion in the PS/P 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 made therein, in light
of the circumstances under which they were made, not misleading. Galen and
Warner shall use all commercially reasonable efforts to have such Form F-4
declared effective under the Securities Act as promptly as practicable after
filing. Galen shall also take any action required to be taken under any
applicable provincial or state securities laws (including United States "Blue
Sky" laws) in connection with the issuance of the Galen Shares in the
Acquisition; provided, however, that neither Galen nor Warner shall be required
to register or qualify as a foreign corporation or to take any action that would
subject it to service of process in any jurisdiction where any such entity is
not now so subject.

                  (h) Each of Warner and Galen shall use its reasonable best
efforts to cause all conditions precedent set forth herein to be fulfilled and
to avoid the occurrence of, or cure, any event which may prevent such conditions
precedent set forth herein from being fulfilled.

            SECTION 1.02 Additional Actions and Undertakings.

                  (a) Galen agrees to be bound by, and allot and issue Galen
Shares pursuant to, the Scheme upon its becoming effective and upon and subject
to the terms and conditions of this Agreement to cooperate fully with Warner in
providing such information and executing such documents and taking such other
actions reasonably within Galen's power as may be necessary or desirable for the
purpose of giving effect to the Scheme.

                  (b) As promptly as practicable following the date of this
Agreement, Galen shall file with the SEC a registration statement on Form 20-F
(the "Registration Statement") under the U.S. Securities Exchange Act of 1934
(the "Exchange Act"). Galen hereby represents and warrants to Warner that the
Registration Statement and all information concerning Galen and its Subsidiaries
supplied by Galen for inclusion in the Proxy Statement will comply in all
material respects with the provisions of applicable federal securities laws, and
on the date filed with the SEC, on the date first published, sent or given to
Warner Shareholders, shall not contain any untrue statement of a material fact
or omit to state any material fact required to be stated therein or necessary in
order to make the statements made therein, in light of the circumstances under
which they were made, not misleading (provided that for the purposes of this
Agreement Galen makes no representation or warranty with respect to any
information concerning Warner and its Subsidiaries supplied by Warner for
inclusion in the Registration Statement). Each of Galen and Warner agrees
promptly to correct any information provided by it for use in the Proxy
Statement or the Registration Statement, if and to the extent that it shall have
become false or misleading in any material respect and Galen further agrees to
take all steps necessary to cause the Registration Statement as so corrected to
be filed with the SEC, in each case, as and to the extent required by applicable
federal securities laws.

                  (c) Galen shall, as soon as practicable after the date of this
Agreement


                                       6
<PAGE>   9

limitation the listing rules made pursuant to the Financial Services Act 1986
(the "Listing Rules"):

                        (i) duly convene and hold an extraordinary general
                  meeting (such meeting, including any adjournment thereof,
                  being the "Galen Meeting") of holders of Galen Shares (the
                  "Galen Shareholders"), for the purpose of considering and
                  voting upon (among other things) an ordinary resolution to (A)
                  approve this Agreement and the Transactions; (B) increase the
                  authorized share capital of Galen to create additional Galen
                  Shares; and (C) authorize the directors of Galen to allot
                  Galen Shares pursuant to the Scheme and the Transactions and
                  to take such other actions, if any, as may be necessary to
                  give effect to this Agreement, the Scheme and the Transactions
                  (the passing of such a resolution by a majority of the votes
                  cast at the Galen Meeting being referred to in this Agreement
                  as the "Galen Shareholder Approval");

                        (ii) prepare and submit to the competent authority for
                  listing in the United Kingdom for purposes of Part IV of the
                  Financial Services Act 1986 (the "UK Listing Authority" or
                  "UKLA") for approval a document or documents comprising (A) a
                  class one circular to Galen Shareholders (or such other
                  document as may be required by the UKLA), including a notice
                  convening the Galen Meeting and (B) listing particulars in
                  respect of the new Galen Shares to be issued pursuant to the
                  Scheme, in each case containing all information required by
                  applicable law and the Listing Rules (such document or
                  documents collectively the "Listing Particulars");

                        (iii) give Warner and its advisers all reasonable
                  opportunity to review and comment on drafts of the Listing
                  Particulars before such drafts are submitted to the UKLA, duly
                  take account of any comments made thereon in relation to
                  information on Warner and in relation to the Transactions and,
                  to the extent reasonably practicable, provide copies of
                  comments from the UKLA thereon to Warner and its advisers as
                  soon as practicable after the same are received;

                        (iv) subject to final approval by the UKLA, procure that
                  the Listing Particulars are duly delivered to the Registrar of
                  Companies in Northern Ireland, published in accordance with
                  applicable law and the Listing Rules and dispatched to Galen
                  Shareholders in a manner sufficient to give lawful notice of
                  the Galen Meeting;

                        (v) apply for admission of the Galen Shares to be issued
                  pursuant to the Transactions to trading on the LSE in
                  accordance with the LSE's Admission and Disclosure Standards
                  for Listed Companies, or other relevant requirements, as
                  applicable.


                                       7
<PAGE>   10
Without prejudice to any right it may have to terminate this Agreement, Galen
shall, if necessary under applicable law and the Listing Rules, promptly publish
supplementary Listing Particulars and, if required by the UKLA or the LSE or
applicable law, re-solicit votes of Galen Shareholders in support of the
Transactions. The provisions of paragraphs (c)(ii) to (iv) above shall apply in
the same manner in relation to any supplementary listing particulars and for
purposes of this Agreement references to the Listing Particulars shall where
appropriate include any such supplementary listing particulars.

                  (d) Galen shall include in the Listing Particulars the
recommendation of the Board of Directors of Galen (the "Galen Board") to Galen
Shareholders to vote in favor of the resolutions to be proposed at the Galen
Meeting referred to in Section 1.02(c)(i) (such recommendation to the Galen
Shareholders being referred to as the "Galen Board Recommendation" and
references to the Galen Board Recommendation herein to include, where the
context so allows, a recommendation against any proposed adjournment of the
Court Meeting or the Galen EGM other than due to practical difficulties);
provided, however, that such recommendation may be withdrawn, modified or
amended to the extent the Galen Board determines, in good faith, after taking
due account of advice from its outside counsel as to legal matters and from its
independent financial advisers as to financial matters, that its fiduciary
duties would be likely to require it to do so.

                  (e) Warner shall cooperate with Galen in the preparation of
the Listing Particulars and provide in a timely manner such information about
Warner and its subsidiaries and the directors, employees, business, prospects
and finances thereof as may be necessary or reasonably requested in connection
therewith.

                           ARTICLE II -- ADS EXCHANGE

Prior to the posting of the Proxy Statement to Warner Shareholders, Warner and
Galen shall, so far as lies within their respective powers, take such actions
and enter into such agreements or arrangements with the Depositary, on terms
reasonably satisfactory to Warner and Galen, as may be necessary or appropriate
to provide for holders of Warner ADSs to receive (at no additional cost to such
holders) whole Galen ADSs representing (as nearly as practicable) the number of
Galen Shares comprised in the consideration received by the Depositary in
respect of the Scheme Shares represented by their Warner ADSs in accordance with
reasonable and customary exchange procedures for securities traded on Nasdaq.

                       ARTICLE III -- OPTIONS AND WARRANTS

            SECTION 3.01. Warner and Galen shall use their respective reasonable
best efforts to implement arrangements whereby each and every option and warrant
to purchase Warner Shares granted under the Warner Option Plan or pursuant to
any other arrangement adopted by the Warner Board to provide options, warrants
or other rights to acquire share capital of Warner (in any such case an
"Option") which is outstanding prior to the Effective Time shall be adjusted or
otherwise modified so as to become, with effect from the Effective Time, an


                                       8
<PAGE>   11
option, warrant or other such right as aforesaid to acquire such number of Galen
Shares (a "Substitute Option") at such exercise price per Galen Share as shall
be determined by applying the following formulae:

Every one Warner share subject to an Option immediately prior to the Effective
Time shall be multiplied by the Per Share Consideration (rounded down to the
nearest whole number, if necessary) and the exercise price per Warner Share
immediately prior to the Effective Time shall be divided by the Per Share
Consideration (rounded up to the nearest cent) and except as provided above in
this Section 3.01, each Substitute Option shall after the Effective Time
continue to be subject to the provisions of the Warner Option Plan and shall be
exercisable upon the same terms and conditions as were applicable under the
Warner Option Plan immediately prior to the Effective Time. It is the intention
of the parties that the above formulae shall be applied in a manner consistent
with Section 424(a) of the Code. Galen shall take all corporate action necessary
to reserve for issuance a sufficient number of Galen Shares for delivery upon
exercise of Substitute Options. Promptly following the Effective Time, Galen
shall file a registration statement on Form S-8 or another appropriate form with
respect to the Galen Shares subject to such options and shall use its reasonable
best efforts to maintain the effectiveness of such registration statement or
registration statements (and maintain the current status of the prospectus or
prospectuses contained therein) for so long as such options remain outstanding.
With respect to those individuals who subsequent to the Transactions will be
subject to the reporting requirements under Section 16(a) of the Exchange Act,
where applicable, to the extent that the arrangements referred to in Section
3.01 are implemented Galen shall cause its Board of Directors to specifically
approve the transactions in this Article III and shall administer options in a
manner that complies with Rule 16b-3 promulgated under the Exchange Act to the
extent the Warner Option Plan complied with such rule prior to the Transactions.

            SECTION 3.02. Warner shall procure that no amendments shall be made
to the Warner Option Plan other than as reasonably necessary to effect the
provisions of Section 3.01 above.


             ARTICLE IV -- REPRESENTATIONS AND WARRANTIES OF WARNER

            Except as disclosed in the letter delivered to Galen concurrently
herewith and designated therein as the Warner Disclosure Letter (the "Warner
Disclosure Letter"), in each case with specific reference to the Section to
which exception is taken, and except as disclosed in the Warner SEC Documents,
Warner hereby represents and warrants to Galen as follows:

            SECTION 4.01 Corporate Organization.

                  (a) Warner is a public limited company duly incorporated and
validly existing under the laws of Ireland. Warner has the corporate power and
authority to own or lease all of its properties and assets and to carry on its
business as it is now being conducted, and is duly licensed or qualified to do
business in each jurisdiction in which the nature of the business


                                       9
<PAGE>   12
conducted by it or the character or location of the properties and assets owned
or leased by it makes such licensing or qualification necessary, except where
the failure to be so licensed or qualified would not have or is not likely to
have with due regard to all circumstances a Material Adverse Effect on Warner.
As used in this Agreement, the term "Material Adverse Effect" means, with
respect to Galen or Warner, as the case may be, a material adverse effect on (i)
the business, operations, results of operations or financial condition of such
party and its Subsidiaries taken as a whole or (ii) the ability of such party to
consummate the transactions contemplated hereby. As used in this Agreement, the
word "Subsidiary" means any corporation, partnership, limited liability company,
joint venture or other legal entity of which Galen or Warner, as the case may be
(either alone or through or together with any other Subsidiary), (A) owns,
directly or indirectly, 50% or more of the stock or other equity interests the
holders of which are generally entitled to vote for the election of the board of
directors or other governing body of such corporation, partnership, limited
liability company, joint venture or other legal entity, (B) is a general
partner, trustee or other entity or person performing similar functions or (C)
has control (as defined in Rule 405 under the Securities Act). For all purposes
of this Agreement, a "wholly-owned Subsidiary" shall be deemed to include those
entities which, for regulatory or other local law purposes, have issued nominal
ownership interests to persons other than Warner or Galen or their respective
Subsidiaries. True and complete copies of the Memorandum and Articles of
Association (the "Warner Memorandum and Articles") of Warner, as in effect as of
the date of this Agreement, have previously been made available by Warner to
Galen.

                  (b) The only Subsidiaries of Warner are those listed in
Section 4.01(b) of the Warner Disclosure Letter. Each Warner Subsidiary (i) is
duly organized and validly existing under the laws of its jurisdiction of
organization, (ii) is duly qualified to do business and in good standing (where
applicable) in all jurisdictions (whether federal, state, local or foreign)
where its ownership or leasing of property or the conduct of its business
requires it to be so qualified and in which the failure to be so qualified would
have or be likely to have a Material Adverse Effect on Warner and (iii) has all
requisite corporate power and authority to own or lease its properties and
assets and to carry on its business as now conducted.

                  (c) Save as disclosed in Section 4.01(c) of the Warner
Disclosure Letter the minute books of Warner are fully up-to-date and accurately
reflect in all material respects all material corporate actions held or taken
since January 1, 1999 of its shareholders and Board of Directors (including
committees of the Board of Directors of Warner).

            SECTION 4.02   Capitalization.

                  (a) The authorized share capital of Warner consists of
50,000,000 shares of Warner Shares, of which, as of April 30, 2000, 12,391,827
shares were issued and outstanding and (ii) 30,000 Deferred Shares, par value
one Irish punt per share, of Warner (the "Warner Deferred Shares"), all of
which, as of April 30, 2000, were designated, issued and outstanding. All of the
issued and outstanding Warner Shares have been duly authorized and validly
issued and are fully paid, non-assessable and free of preemptive rights, with no
personal liability attaching to the ownership thereof. As of April 30, 2000,
except pursuant to the terms of


                                       10
<PAGE>   13
options issued pursuant to the Warner Incentive Share Option Scheme (the "Warner
Option Plan") and Options and Warrants listed in Section 4.02 of the Warner
Disclosure Letter, Warner does not have and is not bound by any outstanding
subscriptions, options, warrants, calls, commitments or agreements of any
character calling for the purchase, transfer, sale or issuance of any Warner
Shares or any other equity securities of Warner or any securities representing
the right to purchase or otherwise receive any Warner Shares or Warner Deferred
Shares. As of April 30, 2000, no Warner Shares are reserved for issuance, except
for 1,573,707 Warner Shares reserved for issuance upon exercise of share options
granted pursuant to the Warner Option Plan (the "Warner Stock Options") and the
2,619,023 Warner Shares reserved for issuance under the Warrants described in
Section 4.02 of the Warner Disclosure Letter. Save as referred to in Section
4.02 of the Warner Disclosure Letter since December 31, 1999, Warner has not
issued any shares in its capital or any securities convertible into or
exercisable for any shares in its capital, other than pursuant to the exercise
of Warner Stock Options granted prior to such date.

                  (b) Warner owns, directly or indirectly, all of the issued and
outstanding shares in its capital or other equity ownership interests of each of
the Warner Subsidiaries as set forth in Section 4.02(b) of the Warner Disclosure
Letter, free and clear of any Liens other than as set forth in Section 4.02(b)
of the Warner Disclosure Letter, and all of such shares or equity ownership
interests are duly authorized and validly issued and are fully paid,
non-assessable and free of preemptive rights, with no personal liability
attaching to the ownership thereof. No Warner Subsidiary has or is bound by any
outstanding subscriptions, options, warrants, calls, commitments or agreements
of any character calling for the purchase or issuance of any shares in its
capital or any other equity security of such Subsidiary or any securities
representing the right to purchase or otherwise receive any shares in its
capital or any other equity security of such Subsidiary.

            SECTION 4.03   Authority; No Violation.

                  (a) Subject to passing of the resolutions to be proposed at
the Court Meeting and the Warner EGM and to the issue of the Final Court Order
and registration thereof by the Registrar of Companies in Ireland, Warner has
all requisite corporate power and authority to execute and deliver this
Agreement and to consummate the transactions contemplated hereby, and no other
corporate proceedings on the part of Warner are necessary to approve and adopt
this Agreement and to consummate the transactions contemplated hereby. Without
prejudice to any other provisions of this Agreement, the consummation of the
transactions contemplated hereby has been duly and validly approved and declared
advisable by the Warner Board. This Agreement has been duly and validly executed
and delivered by Warner and (assuming due authorization, execution and delivery
by Galen of this Agreement) constitutes a valid and binding obligation of
Warner, enforceable against Warner in accordance with its terms.

                  (b) Neither the execution and delivery of this Agreement by
Warner nor the consummation by Warner of the transactions contemplated hereby,
nor compliance by Warner with any of the terms or provisions hereof, will (i)
violate any provision of the Warner Memorandum and Articles or similar
bylaw/organizational documents of its Subsidiaries or (ii)


                                       11
<PAGE>   14
assuming that the consents and approvals, filings or waiting times referred to
in Section 4.04 are duly obtained, made or elapsed respectively (x) violate any
statute, code, ordinance, rule, regulation, judgment, order, writ, decree or
injunction applicable to Warner or any of its Subsidiaries or any of their
respective properties or assets, or (y) violate, conflict with, result in a
breach of any provision of or the loss of any benefit under, constitute a
default (or an event which, with notice or lapse of time, or both, would
constitute a default) under, result in the termination of or a right of
termination or cancellation under, accelerate the performance required by, or
result in the creation of any Lien upon any of the respective properties or
assets of Warner or any of its Subsidiaries under, any of the terms, conditions
or provisions of any note, bond, mortgage, indenture or other agreement,
instrument for borrowed money, any guarantee of any agreement or instrument for
borrowed money or any license, lease or any other agreement or instrument
("Material Agreement") to which Warner or any of its Subsidiaries is a party, or
by which they or any of their respective properties or assets may be bound or
affected, except (in the case of clause (y) above) for such violations,
conflicts, breaches or defaults which, either individually or in the aggregate,
will not have and is not likely to have a Material Adverse Effect on Warner.

            SECTION 4.04 Consents and Approvals. Except (i) in connection, or in
compliance, with the provisions of the Hart-Scott-Rodino Antitrust Improvements
Act of 1976, as amended (the "HSR Act"), (ii) for the filing of any required
applications or notices with any state or foreign agencies and approval of such
applications and notices (the "State and Foreign Approvals"), (iii) in
connection with applicable requirements of the Mergers Act, (iv) for such
filings and approvals as are required to be made or obtained under the

issuance or listing of the shares of Galen Shares pursuant to this Agreement,
(v) for the approval of this Agreement by the requisite vote of the shareholders
of Galen, (vi) in connection, or in compliance, with the Securities Act or
Exchange Act, and (vii) the passing of the resolutions to be proposed at the

registration thereof by the Registrar of Companies in Ireland, no consents or
approvals of or filings or registrations with any court, administrative agency
or commission or other governmental authority or instrumentality (each a
"Governmental Entity") or with any third party are necessary in connection with
(A) the execution and delivery by Warner of this Agreement and (B) the
consummation by Warner of the Transaction and the other transactions
contemplated by this Agreement, failure at which to make or obtain could not
reasonably be expected to have a Material Adverse Effect on Warner or impair or
delay the ability of either party to consummate the Transactions contemplated
hereby.

            SECTION 4.05 SEC Documents and Other Reports. Warner has filed all
required documents with the SEC since January 1, 1999 (the "Warner SEC
Documents"). As of their respective dates, the Warner SEC Documents complied in
all material respects with the requirements of the Securities Act or the
Exchange Act, as the case may be, and, at the respective times they were filed,
none of the Warner SEC Documents contained any untrue statement of a material
fact or omitted to state a material fact required to be stated therein or
necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading. The consolidated financial
statements (including, in each case, any notes thereto) of


                                       12
<PAGE>   15
Warner included in the Warner SEC Documents complied as to form in all material
respects with applicable accounting requirements and the published rules and
regulations of the SEC with respect thereto as of their respective dates of
filing, were prepared in accordance with generally accepted accounting

involved (except as may be indicated therein or in the notes thereto) and fairly
presented in all material respects the consolidated financial position of Warner
and its consolidated Subsidiaries as of the respective dates thereof and the
consolidated results of their operations and their consolidated cash flows for
the periods then ended (subject, in the case of unaudited statements, to normal
year-end audit adjustments and to any other adjustments described therein).
Except as disclosed in the Warner SEC Documents or as required by U.S. GAAP,
Warner has not, since December 31, 1999, made any change in the accounting
practices or policies applied in the preparation of its financial statements.

            SECTION 4.06   Registration Statement; Listing Particulars

                   (a) None of the information supplied or to be supplied by
Warner for inclusion or incorporation by reference in the Registration Statement
at the time it becomes effective under the Exchange Act, or the Registration
Statement on Form F-4 (if filed) at the time it becomes effective under the
Securities Act, will contain any untrue statement of a material fact or omit to
state any material fact required to be stated therein or necessary in order to
make the statements therein not misleading.

                  (b) All the information supplied or to be supplied by Warner

particulars required to be published) on the date the Listing Particulars (or,
if applicable, supplementary listing particulars) are first mailed to

approval of the Transactions will be true and accurate in all material respects,
will not be misleading in any material respect, and will not omit any
information known or which could on reasonable enquiry have been known to the

or in Section 4.07 of the Warner Disclosure Letter and except for the

certificates, approvals and orders of any Governmental Entity (collectively,
"Permits") necessary for Warner or any of its Subsidiaries to own, lease and
operate its properties or to carry on its business as it is now being conducted
(the "Warner Permits"), except where the failure to have any of the Warner
Permits would not, individually or in the aggregate, have or be likely to have a
Material Adverse Effect on Warner, and, as of the date of this Agreement, no
suspension or cancellation of any of the Warner Permits is pending or, to the
Knowledge of Warner, threatened, except where the suspension or cancellation of
any of the Warner Permits, individually or in the aggregate, would not have or
be likely to have a Material Adverse Effect on Warner. Neither Warner nor any of
its Subsidiaries is in violation of (i) its charter, by-laws or equivalent
documents, (ii) any applicable law, ordinance, administrative or governmental
rule or regulation or (iii) any order, decree or judgment of any Governmental

Tax Returns required to have been filed or appropriate extensions therefor have
been properly obtained, and to the Knowledge of Warner such Tax Returns are

in excess of US$100,000 (in aggregate), (iii) Warner and each of its
Subsidiaries have complied in all material respects with all rules and

Warner; (iv) neither Warner nor any of its Subsidiaries has waived any statute

            SECTION 4.12   ERISA.

                  (a) Section 4.12(a)(X) of Warner Disclosure Letter contains a
list of each Warner Plan. With respect to each Warner Plan, Warner has made
available to Galen a true and correct copy of (i) the most recent annual report
(Form 5500) filed with the IRS, (ii) such Warner Plan and all amendments
thereto, (iii) each trust agreement, insurance contract or administration
agreement relating to such Warner Plan, (iv) the most recent summary plan
description for each Warner Plan for which a summary plan description is
required, (v) the most recent actuarial report or valuation relating to a Warner
Plan subject to Title IV of the Employee Retirement Income Security Act of 1974
and the regulations promulgated thereunder ("ERISA"), (vi) the most recent
determination letter, if any, issued by the IRS with respect to any Warner Plan
intended to be qualified under Section 401(a) of the Code, (vii) any request for
a determination currently pending before the IRS and (viii) all correspondence
with the IRS, the Department of Labor or the Pension Benefit Guaranty
Corporation relating to any outstanding controversy. Each Warner Plan complies
with ERISA, the Code and all other applicable statutes and governmental rules
and regulations, except any failure to comply as would not have or be likely to
have, individually or in the aggregate, a Material Adverse Effect on Warner.
Except as set forth in Section 2.12(a)(Y) of the Warner Disclosure Letter, (i)
no "reportable event" (within the meaning of Section 4043 of ERISA) has occurred
within the past three years with respect to any Warner Plan which could result
in liability to Warner, (ii) neither Warner nor any of its ERISA Affiliates (as
hereinafter defined) has withdrawn from any Warner Multiemployer Plan (as
hereinafter defined) at any time or instituted, or is currently considering
taking, any action to do so, and (iii) no action has been taken, or is currently
being considered, to terminate any Warner Plan subject to Title IV of ERISA.

                  (b) There has been no failure to make any contribution or pay
any amount due to any Warner Plan as required by Section 412 of the Code,
Section 302 of ERISA, or the terms of any such Plan, and no Warner Plan, nor any
trust created thereunder, has incurred any "accumulated funding deficiency" (as
defined in Section 302 of ERISA), whether or not waived.

                  (c) With respect to Warner Plans, no event has occurred and,
to the Knowledge of Warner, there exists no condition or set of circumstances in
connection with which Warner or any of its ERISA Affiliates would be subject to
any liability under the terms of such Warner Plans, ERISA, the Code or any other
applicable law which has had, or would have or be likely to have, individually
or in the aggregate, a Material Adverse Effect on Warner. Except as listed on
Section 2.12(c) of the Warner Disclosure Letter, all Warner Plans that are


                                       16
<PAGE>   19
intended to be qualified under Section 401(a) of the Code have been determined
by the IRS to be so qualified, or a timely application for such determination is
now pending or will be filed on a timely basis and, except as listed on Section
2.12(c) of the Warner Disclosure Letter, to the Knowledge of Warner there is no
reason why any Warner Plan is not so qualified in operation. Neither Warner nor
any of its ERISA Affiliates has been notified by any Warner Multiemployer Plan
that such Warner Multiemployer Plan is currently in reorganization or insolvency
under and within the meaning of Section 4241 or 4245 of ERISA or that such
Warner Multiemployer Plan intends to terminate or has been terminated under
Section 4041A of ERISA. To the Knowledge of Warner, neither the termination of
any Warner Multiemployer Plan nor the complete or partial withdrawal by Warner
or any of its ERISA Affiliates from any Warner Multiemployer Plan would result
in any liability of Warner or any of its ERISA Affiliates that would have or be
likely to have, individually or in the aggregate, a Material Adverse Effect on
Warner. Except as set forth in Section 2.12(c) of the Warner Disclosure Letter,
neither Warner nor any of its ERISA Affiliates has any liability or obligation
under any welfare plan to provide life insurance or medical benefits after
termination of employment to any employee or dependent other than as required by
(i) Part 6 of Title I of ERISA or (ii) the laws of a jurisdiction outside the
United States.

                  (d) As used in this Agreement, (i) "Warner Plan" means a
"pension plan" (as defined in Section 3(2) of ERISA (other than a Warner
Multiemployer Plan (as hereinafter defined))), "Welfare Plan" means a welfare
plan as defined in Section 3(1) of ERISA, or any material bonus, profit sharing,
deferred compensation, incentive compensation, stock ownership, stock purchase,
stock option, phantom stock, vacation, severance, death benefit, insurance or
other plan, arrangement or understanding, in each case established or maintained
or contributed to by Warner or any of its ERISA Affiliates or as to which Warner
or any of its ERISA Affiliates or otherwise may have any liability, whether or
not covered by ERISA (other than a Warner Ex-U.S. Pension Plan (as hereinafter
defined)), (ii) "Warner Multiemployer Plan" means a "multiemployer plan" (as
defined in Section 4001(a)(3) of ERISA) to which Warner or any of its ERISA
Affiliates is or has been obligated to contribute or otherwise may have any
liability, and (iii) with respect to any person, "ERISA Affiliate" means any
corporation or trade or business (whether or not incorporated) which is under
common control, or otherwise would be considered a single employer with such
person pursuant to Section 414(b), (c), (m) or (o) of the Code and the
regulations promulgated thereunder or pursuant to Section 4001(b) of ERISA and
the regulations promulgated thereunder.

                  (e) Section 4.12(e) of the Warner Disclosure Letter contains a
list of each Warner Ex-U.S. Pension Plan (as hereinafter defined) and Warner has
provided to Galen a copy of any written plan document. Except as would not have,
nor be likely to have, individually or in the aggregate, a Material Adverse
Effect on Warner, each such plan has been maintained in compliance with all
applicable laws, orders and regulations, and the fair market value of the assets
of each such plan which is intended to be a funded Warner Ex-U.S. Pension Plan
or arrangement equals or exceeds the value of the accrued benefits. As used in
this Agreement, the term "Warner Ex-U.S. Pension Plan" shall mean any
arrangement (other than a Warner Plan) providing retirement pension benefits
that is established or maintained by Warner


                                       17
<PAGE>   20
or any Subsidiary for the benefit of employees who are or were employed outside
the United States.

                  (f) Section 4.12(f) of the Warner Disclosure Letter contains a
list, as of the date of this Agreement, of all (i) severance and employment
agreements with officers of Warner and each ERISA Affiliate, (ii) severance
programs and policies of Warner with or relating to its employees and (iii)
plans, programs, agreements and other arrangements of Warner with or relating to
its employees which contain change of control or similar provisions, in each
case involving a severance or employment agreement or arrangement with an
individual officer or employee, only to the extent such agreement or arrangement
provides for minimum annual payments in excess of US$100,000. Warner has
provided to Galen a true and complete copy of each of the foregoing.

            SECTION 4.13 Labor Matters. Except as disclosed in Section 4.13 of
the Warner Disclosure Letter, neither Warner nor any of its Subsidiaries is
party to any collective bargaining agreement or other labor agreement with any
union or labor organization and no union or labor organization has been
recognized by Warner or any of its Subsidiaries as an exclusive bargaining
representative for employees of Warner or any of its Subsidiaries. Neither
Warner nor any of its Subsidiaries is the subject of any material proceeding
asserting that it or any of its Subsidiaries has committed an unfair labor
practice or is seeking to compel it to bargain with any labor union or labor
organization nor is there pending or, to the Knowledge of Warner, threatened,
nor has there been for the past three years, any labor strike, dispute, walkout,
work stoppage, slow-down or lockout involving it or any of its Subsidiaries,
except in each case as would not, individually or in the aggregate, have or be
likely to have a Material Adverse Effect on Warner.

            SECTION 4.14 Intellectual Property. Except as set forth in Section
4.14 of the Warner Disclosure Letter, Warner and its Subsidiaries own or have a
valid, enforceable right to use free from any encumbrances, other than those
that would not have or be likely to have a Material Adverse Effect on Warner,

trade names, service marks, trade secrets, trade dress, corporate names, logos
and slogans (and all translations, adaptations, derivations and combinations of
the foregoing), design rights, database rights, copyrights, inventions,

registration or registrations of any of the foregoing and other proprietary
intellectual property rights (collectively, "Intellectual Property Rights")
necessary to conduct the business of Warner and its Subsidiaries, taken as a
whole, except where the failure to have such Intellectual Property Rights,
individually or in the aggregate, would not have or be likely to have a Material
Adverse Effect on Warner. Except as set forth in Section 4.14 of the Warner
Disclosure Letter, neither Warner nor any of its Subsidiaries has infringed any
Intellectual Property Rights of any third party other than any infringements
that, individually or in the aggregate, would not have a or be likely to have
Material Adverse Effect on Warner. Neither Warner nor its Subsidiaries are aware
of any infringement or misappropriation by any person


                                       18
<PAGE>   21
with respect to the Intellectual Property Rights owned or used by Warner or its
Subsidiaries other than any such infringement or misappropriation that would not
have or be likely to have a Material Adverse Effect on Warner. All Intellectual
Property Rights owned or used by Warner or its Subsidiaries as of the date
hereof will be owned or available for use by Warner and its Subsidiaries on
terms and conditions immediately following the Effective Date that are not
materially different from those existing prior to the Effective Date.

            SECTION 4.15 Environmental and Safety Matters.

                  (a) Except as set forth in Section 4.15 of the Warner
Disclosure Letter, the operations of Warner and Subsidiaries have complied and
are in compliance with all applicable federal, state, local, regional and
foreign laws, rules and regulations, orders, decrees, common law, judgments,
permits and licenses relating to public and worker health and safety
(collectively, "Worker Safety Laws") and relating to the protection, regulation

individually or in the aggregate, have not had, and would not have, a Material
Adverse Effect on Warner. To the best of Warner's Knowledge with respect to
properties and assets of Warner including any previously owned, leased or
operated properties or assets, there are no past, present or reasonably
anticipated future events, conditions, circumstances, activities, practices,
incidents, actions or plans of Warner or any of its predecessors or Subsidiaries
that would interfere with or prevent compliance or continued compliance with or
give rise to any liabilities or investigatory, corrective or remedial
obligations under applicable Worker Safety Laws or Environmental Laws, other

individually or in the aggregate, has not had, and would not have, a Material
Adverse Effect on Warner.

with all Environmental Laws and Worker Safety Laws, other than any such activity
that, individually or in the aggregate, has not had, and would not have, a
Material Adverse Effect on Warner. Warner and its Subsidiaries have not reported
to any Governmental Entity, or been notified by any Governmental Entity of the
existence of, any material violation of an Environmental Law or any release,
discharge or emission of any hazardous or toxic materials, substances, wastes,
pollutants or contaminants, other than any such violation, release, discharge or
emission that, individually or in the aggregate, has not had, and would not
have, a Material Adverse Effect on Warner.

                  (c) With respect to Warner, neither this Agreement nor the
consummation of the transactions that are the subject of this Agreement will
result in any


                                       19

warranties of Warner with respect to all matters arising under Environmental
Laws and Worker Safety Laws.

            SECTION 4.16 Insurance. Warner and its Subsidiaries have in effect

premiums, types and risks insured, constitutes reasonably adequate coverage
against all risks customarily insured against by companies of comparable size
and with similar operations.

            SECTION 4.17 Opinion of Financial Advisor. Warner has received the
written opinion of CSFB to the effect that, as of the date thereof, the
consideration to be offered to the holders of Warner Shares and Warner ADSs
(other than Galen and its affiliates) pursuant to the Scheme is fair to such
holders from a financial point of view, a copy of which opinion has been
delivered to Galen.

            SECTION 4.18 Broker's Fees. Except as set forth in the engagement
letter agreement between Warner and CSFB, a true and complete copy of which has
previously been provided to Galen, neither Warner nor any Warner Subsidiary nor
any of their respective officers or directors has employed any broker or finder
or incurred any liability for any broker's fees, commissions or finder's fees in
connection with the Transactions or related transactions contemplated by this
Agreement.

                  (a) Section 4.19(a) of the Warner Disclosure Letter lists each
material parcel of real property owned by Warner or any of its Subsidiaries (the

first refusal to purchase such Warner Owned Property or any portion thereof or
interest therein, and (iii) Warner or Subsidiary is not a party to any agreement

                                       20
<PAGE>   23
and leased property of either Warner or Galen ("Real Property"): (A) real estate
taxes, assessments and other governmental levies, fees or charges imposed with
respect to such Real Property which are not due and payable as of the Effective
Time or which are being contested by appropriate proceedings; (B) mechanics
liens and similar liens for labor, materials or supplies provided with respect
to such Real Property incurred in the ordinary course of business for amounts
which are not delinquent and which would not, individually or in the aggregate,
have a material adverse effect on the business or which are being contested by
appropriate proceedings; (C) zoning, building codes and other land use Laws
regulating the use or occupancy of such Real Property or the activities

violation of which would not have a material adverse effect on the business; (D)
easements, covenants, conditions, restrictions and other similar matters
affecting title to such Real Property and other title defects which do not
materially impair the use or occupancy of such Real Property or the operation of
the business.

                  (b) Section 4.19(b) of the Warner Disclosure Letter sets forth
a list of all material leases, subleases and other occupancy agreements,
including all amendments, extensions and other modifications (the "Warner
Leases") for real property (the "Warner Leased Property"; the Warner Owned

Subsidiary has a good and valid leasehold interest in and to all of the Warner
Leased Property, subject to no Liens except Permitted Liens as described in
Section 4.19(b) of the Warner Disclosure Letter. Each Warner Lease is in full
force and effect and is enforceable in accordance with its terms. There exists
no default or condition which, with the giving of notice, the passage of time or
both, could become a default under any Warner Lease in any case, that would have
a Material Adverse Effect on Warner or materially impair Warner's rights to or
ability to use any such property. Warner has previously delivered to Galen true
and complete copies of all the Warner Leases. Except as described on Section
4.19(b) of the Warner Disclosure Letter, no consent, waiver, approval or
authorization is required from the landlord under any Warner Lease as a result
of the execution of this Agreement or the consummation of the transactions
contemplated hereby the failure to obtain would have a Material Adverse Effect
on Warner or materially impair Warner's rights to or ability to use any such
property.

                  (c) Real Property Used in The Business. The Warner Owned
Property identified in Schedule 4.19(a) and the Warner Leased Property
identified in Schedule 4.19(b) comprise all of the real property used or
intended to be used in, or otherwise related to, the Warner business.

            SECTION 4.20 Material Contracts. There have been made available to
Galen, its affiliates and their representatives true and complete copies of all
of the following contracts to which Warner or any of its Subsidiaries is a party
or by which any of them is bound (collectively, the "Warner Material
Contracts"): (i) contracts with any current officer or director of Warner or any
of its Subsidiaries; (ii) contracts for the sale of any of the assets of Warner
or any of its


                                       21
<PAGE>   24
Subsidiaries other than in the ordinary course of business or for the grant to
any person of any preferential rights to purchase any of its assets other than
inventory in the ordinary course of business; (iii) contracts containing
covenants of Warner or any of its Subsidiaries not to compete in any line of
business or with any person in any geographical area or covenants of any other

agreements, mortgages, promissory notes, and all contracts relating to the
borrowing of money; and (v) all other agreements contracts or instruments which,
in the reasonable opinion of Warner, are material to Warner or any of its
Subsidiaries. Except as set forth in Section 4.20 of the Warner Disclosure
Letter or as would not have or be likely to have a Material Adverse Effect on
Warner, all of the Warner Material Contracts are in full force and effect and
are the legal, valid and binding obligation of Warner or its Subsidiaries,
enforceable against them in accordance with their respective 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 as set forth
in Section 4.20 of the Warner Disclosure Letter, neither Warner nor any
Subsidiary is in default in any material respect under any Warner Material
Contract nor, to the Knowledge of Warner, is any other party to any Warner
Material Contract in default thereunder in any material respect except, in each
case, for those defaults that, individually or in the aggregate, would not have
or be likely to have a Material Adverse Effect on Warner.

            SECTION 4.21 Compliance with Laws. Warner has conducted its business
and operations in compliance with, and obtained all permits, licenses and other
authorizations required under, all applicable laws, rules, regulations, orders,
ordinances, judgments and decrees of all governmental authorities (foreign,
federal, state and local) (collectively "Laws") including, where applicable, all
requirements imposed by the U.S. Food and Drug Administration (the "FDA"),
except for such non-compliance which Warner does not reasonably expect would
have or would be likely to have a Material Adverse Effect. To the Knowledge of
Warner, Warner has not within the past 24 months received written notice of any
non-compliance with respect to, or potential liability under, any Laws, which
has not been satisfied or otherwise resolved, and there are no circumstances to
the Knowledge of Warner which are reasonably likely to give rise to any such
non-compliance except for such non-compliance which Warner does not reasonably
expect would have a Material Adverse Effect.


            SECTION 4.22 Warner Approvals. The approval of the Scheme by Warner
Shareholders at the Court Meeting and the passing of the Warner EGM Resolution
and the sanction of the Scheme by the Court are the only actions required by

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 as
set forth in Section 5.19 of the Galen Disclosure Letter, neither Galen nor any
Subsidiary is in default in any material respect under any Galen Material
Contract nor, to the Knowledge of Galen, is any other party to any Galen
Material Contract in default thereunder in any material respect except, in each
case, for those defaults that, individually or in the aggregate, would not have
a Material Adverse Effect on Galen.

            SECTION 5.20 Compliance with Laws. Galen has conducted its business
and operations in compliance with, and obtained all permits, licenses and other
authorizations required under, all Laws, including, without limitation, all
requirements imposed by the FDA and comparable foreign regulatory authorities,
including, where applicable, the Medicines Act 1968 and the rules made and
marketing authorizations granted thereunder and the regulations of the UK
Department of Health governing the sale of products to the National Health
Service, except for such non-compliance which Galen does not reasonably expect
would have or be likely to have a Material Adverse Effect. To the Knowledge of
Galen, Galen has not within the past 24 months received written notice of any
non-compliance with respect to, or potential liability under, any Laws, which
has not been satisfied or otherwise resolved, except for such non-


                                       32
<PAGE>   35
compliance which Galen does not reasonably expect would have or would be likely
to have a Material Adverse Effect and there are no circumstances to the
Knowledge of Galen which are reasonably likely to give rise to any such
non-compliance.

                  (e) declare, set aside, make or pay any dividend or other
distribution, payable in cash, stock, property or otherwise, with respect to any
of its share capital (except for dividends paid by any direct or indirect
wholly-owned Subsidiary of Galen to Galen or to any other direct or indirect
wholly-owned Subsidiary of Galen and except for any interim or final cash

practice and any other acquisitions for consideration that (i) is, in the
aggregate, in excess of US$25,000,000; or (ii) would not be able to be financed
by way of Galen's own internal resources available and subsisting as at the date
of this Agreement provided that any proceeds receivable pursuant to an issue of
shares allowed pursuant to this section 6.02 shall be treated for the purposes
of this sub-section (ii) as internal financial resources available and
subsisting;

                  (h) take any action that would, individually or in the
aggregate, reasonably be expected to make any representation and warranty of

            SECTION 6.03 Access to Information.

                  (a) From the date of this Agreement until the Effective Time,
Warner will, and will cause its Subsidiaries, and each of their respective
officers, directors, counsel, advisors and representatives (collectively, the
"Warner Representatives") to, give Galen and its officers, employees, counsel,
advisors and representatives (collectively, the "Galen Representatives") full
access (subject, however, to existing confidentiality and similar non-disclosure
obligations and the preservation of attorney client and work product privileges
or any further confidentiality assurances which may be required to update or
extend existing confidentiality agreements between the parties in order to
protect Warner's legitimate business interests), during normal business hours,
to the offices and other facilities and to the books and records of Warner and
its Subsidiaries and will cause the Warner Representatives to furnish Galen and
the Galen Representatives to the extent available with such financial and
operating data and such other information with respect to the business and
operations of Warner and its Subsidiaries as Galen may from time to time
reasonably request provided that Galen shall demonstrate to the Warner
Representatives a legitimate interest or purpose in relation to the consummation
of the Transactions for access to such information. Prior to the Closing,
neither Galen nor the Galen Representatives shall contact or in any manner
communicate with the employees, customers, lessors and suppliers of Warner and
its Subsidiaries with respect to any matter related to the transaction
contemplated hereby, except with the prior consent of Warner.

                  (b) From the date of this Agreement until the Effective Time,
Galen will, and will cause its Subsidiaries, and each Galen Representative to,
give Warner and the Warner Representatives full access (subject, however, to
existing confidentiality and similar non-disclosure obligations and the
preservation of attorney client and work product privileges or any further
confidentiality assurances which may be required to update or extend existing
confidentiality agreements between the parties in order to protect Galen's
legitimate business interests), during normal business hours, to the offices and
other facilities and to the books and records of Galen and its Subsidiaries and
will cause the Galen Representatives to furnish Warner and the Warner
Representatives to the extent available with such financial and operating data
and such other information with respect to the business and operations of Galen
and its Subsidiaries as Warner may from time to time reasonably request,
provided that Warner shall demonstrate to


                                       37
<PAGE>   40
the Galen Representatives a legitimate interest or purpose in relation to the
consummation of the Transactions for access to such information. Prior to the
Closing, neither Warner nor the Warner Representatives shall contact or in any
manner communicate with the employees, customers, lessors and suppliers of Galen
and its Subsidiaries with respect to any matter related to the transaction
contemplated hereby, except with the prior consent of Galen.

            SECTION 6.04   Reasonable Best Efforts.

                  (a) Subject to the terms and conditions herein provided and to
applicable legal requirements, each of the parties hereto agrees to use
reasonable best efforts to take, or cause to be taken, all action, and to do, or
cause to be done (consistent with the fiduciary duties of the Board of Directors
of Warner and Galen under applicable law), and to assist and cooperate with the
other parties hereto in doing, as promptly as practicable, all things necessary,
proper, desirable or advisable under applicable laws and regulations to ensure
that the conditions set forth in Article VII are satisfied and to consummate and
make effective the transactions contemplated by the Scheme and this Agreement.

                  (b) If at any time prior to the Closing any event or
circumstance relating to either Warner or Galen or any of their respective
Subsidiaries, should be discovered by Warner or Galen, as the case may be, and
which should be set forth in an amendment or supplement to the Proxy Statement
or the Registration Statement or the Listing Particulars, the discovering party
will promptly inform the other party of such event or circumstance. If at any
time after the Effective Time any further action is necessary or desirable to
carry out the purposes of this Agreement, including the execution of additional
instruments, the proper officers and directors of each party to this Agreement
shall take all such necessary action.

            SECTION 6.05 Consents.

                  (a) Each of the parties will use its reasonable best efforts
to obtain as promptly as practicable all consents of any Governmental Entity or
any other person required in connection with, and waivers of any violations that
may be caused by, the consummation of the transactions contemplated by the this
Agreement. Warner and Galen shall promptly prepare and file as soon as
practicable after the date hereof all documents required to be filed (i) with
the United States Federal Trade Commission and the Department of Justice in
order to comply with the HSR Act and (ii) any other documents which are required
under any non-United States laws regulating competition, antitrust, investment
or exchange controls. Warner and Galen shall promptly furnish all materials
thereafter required in connection therewith.

                  (b) In furtherance and not in limitation of the foregoing,
Galen and Warner shall use their respective best efforts to resolve such
objections, if any, as may be asserted with respect to the transactions
contemplated by this Agreement under any antitrust, competition or trade
regulatory laws, rules or regulations of any domestic or foreign government or
governmental authority or any multinational authority ("Antitrust Laws"). If any
suit is instituted challenging any of the transactions contemplated by this
Agreement as violative of any


                                       38
<PAGE>   41
Antitrust Law, Galen shall use its reasonable best efforts to take such action
as may be required (a) by the applicable government or governmental or
multinational authority (including, without limitation, the Antitrust Division
of the United States Department of Justice, the Federal Trade Commission, the
Irish Department of Enterprise, Trade and Employment or the Competition
Authority of Ireland in order to resolve such objections or (b) by any domestic
or foreign court or similar tribunal, in any suit brought by a private party or
governmental or multinational authority challenging the transactions
contemplated by this Agreement as violative of any Antitrust Law, in order to
avoid the entry of, or to effect the dissolution of, any injunction, temporary
restraining order or other order that has the effect of preventing the
consummation of any of such transactions, provided always that, for the
avoidance of doubt, Galen shall not be obliged by this Section 6.05 to hold
separate or divest any businesses, product lines or assets of Galen or Warner or
any of their Subsidiaries or to agree to do so or to undertake to any such
bodies so to do.

                  (c) Any party hereto shall promptly inform the others of any
material communication from the United States Federal Trade Commission, the
Department of Justice or any other domestic or foreign government or
governmental or multinational authority regarding any of the transactions
contemplated by this Agreement. If any party or any affiliate thereof receives a
request for additional information or documentary material from any such
government or authority with respect to the transactions contemplated by this
Agreement, then such party will endeavor in good faith to make, or cause to be
made, as soon as reasonably practicable and after consultation with the other
party, an appropriate response in compliance with such request. Galen will
advise Warner promptly in respect of any understandings, undertakings or
agreements (oral or written) which Galen proposes to make or enter into with the
Federal Trade Commission, the Department of Justice, or any other domestic or
foreign government or governmental or multinational authority in connection with
the transactions contemplated by this Agreement.

            SECTION 6.06 Public Announcements. The initial press release with
respect to the execution of this Agreement shall be a joint press release
acceptable to Warner and Galen. Thereafter, so long as this Agreement is in
effect, Warner and Galen shall consult with each other before issuing any press
release or otherwise making any public statements with respect to the
Transactions or this Agreement and shall not issue any such press release or
make any such public statement without the prior consent of the other party,
which shall not be unreasonably withheld; provided, however, that a party may,
without the prior consent of the other party, issue such press release or make
such public statement as may upon the advice of counsel be required by law,
Nasdaq, the LSE or the ISE if it has used all reasonable best efforts to consult
with the other party.

            SECTION 6.07 Employee Benefit Arrangements. Galen agrees that it
will honor, or cause Warner to honor, all obligations under employee
arrangements (the "Employee Arrangements") to which Warner or any of its
Subsidiaries is presently a party which are listed in the Employee Arrangements
Schedule. Notwithstanding the foregoing, from and after the Effective Time,
subject to the remaining provisions of this Section 6.07, Galen shall have the


                                       39
<PAGE>   42
right to amend, modify, alter or terminate any Employee Arrangements of Warner;
provided, that any such action shall not in the reasonable opinion of Galen
adversely affect the rights of any employees or other beneficiaries which shall
have arisen (1) under the Warner Option Plan; (2) under any Employee Arrangement
prior to such amendment, modification, alteration or termination; or (3) under
any agreement which requires the consent of the employee or any other party or
beneficiary for amendment, modification, alteration or termination, without
obtaining such consent. Notwithstanding the foregoing, for a period of one year
following the Effective Time, Galen shall continue to provide to employees of
Warner and its Subsidiaries (excluding employees covered by collective
bargaining agreements) broad-based employee benefit plans and arrangements which
are in the aggregate in the reasonable opinion of Galen no less favorable than
those provided to such employees as of the date hereof, provided always that
nothing in this section shall obligate Galen to continue (or procure to be
continued) the employment of any particular employee or employees during such
period. Solely for purposes of eligibility and vesting under Employee
Arrangements (including without limitation plans or programs of Galen and its
affiliates after the Closing), all service with Warner or any of its
Subsidiaries or their predecessors prior to the Closing shall be treated as
service with Galen and its affiliates.

            SECTION 6.08   Indemnification.

                  (a) Galen agrees that all rights to indemnification now
existing in favor of any director or officer of Warner and its Subsidiaries (the
"Indemnified Parties") as provided in their respective charters or by-laws or,
in an agreement between an Indemnified Party and Warner or one of its
Subsidiaries, shall survive the Transactions and shall continue in full force
and effect for a period of not less than six years from the Effective Time;
provided, that in the event any claim or claims are asserted or made within such
six-year period, all rights to indemnification in respect of any such claim or
claims shall continue until final disposition of any and all such claims. After
the Effective Time, Galen agrees to cause Warner to honor all rights to
indemnification referred to in the preceding sentence. Without limitation of the
foregoing, in the event any such Indemnified Party is or becomes involved in any
capacity in any action, proceeding or investigation in connection with any
matter, including, without limitation, the transactions contemplated by this
Agreement, occurring prior to, and including, the Effective Time, Warner will
cause to be paid in accordance with the applicable charters, by-laws and
agreements, as incurred such Indemnified Party's legal and other expenses
(including the cost of any investigation and preparation) incurred in connection
therewith. Galen shall pay all reasonable expenses, including attorneys' fees,
that may be incurred by any Indemnified Party in enforcing the indemnity and
other obligations provided for in this Section 6.08 subject to the limitations
of Northern Ireland law to the extent applicable.

                  (b) Galen agrees that Warner shall cause to be maintained in
effect for not less than six years from the Effective Time the current policies
of the directors' and officers' liability insurance maintained by Warner;
provided, that Galen may substitute therefor other policies not less
advantageous (other than to a de minimus extent) to the beneficiaries of the
current policies and provided that such substitution shall not result in any
gaps or lapses in coverage with respect to matters occurring prior to the
Effective Time; and provided, further, that


                                       40
<PAGE>   43
Galen shall not be required to pay an annual premium in excess of 300% of the
last annual premium paid by Warner prior to the date hereof and if Galen is
unable to obtain the insurance required by this Section 6.08(b) it shall obtain
as much comparable insurance as possible for an annual premium equal to such
maximum amount.

                  (c) Galen, unless prevented by laws or regulations in any
relevant jurisdiction, LSE, UKLA or SEC, shall take, prior to the Effective
Time, all appropriate actions within their remit to appoint to the Galen Board
Messrs. Boissoneault and Herendeen with effect from the Effective Time, provided
that neither of these individuals nor Warner shall have taken any action or
omitted to fulfill any obligation which would result in the termination of his
Employment Agreement or affect the ability of his Employment Agreement to become
unconditional. Galen further agrees (to the extent permitted by law) to
indemnify and hold harmless Roger Boissonneault and Paul Herendeen against and
in respect of all actions, claims, liabilities and losses which they may suffer
or incur as persons responsible for the Listing Particulars to the same extent
as Galen is permitted under applicable law to indemnify its existing directors.

                  (d) Galen agrees that with effect from the publication of the
Listing Particulars it will procure that Roger Boissonneault and Paul Herendeen
shall be covered by Galen's existing Directors and Officers liability insurance
policy in respect of liabilities as proposed Directors of Galen to the same
extent as Galen's existing Directors are so covered.

            SECTION 6.09 Notification of Certain Matters. Galen and Warner shall
promptly notify each other of (a) the occurrence or non-occurrence of any fact
or event which would be reasonably likely (i) to cause any representation or
warranty of any party hereto contained in this Agreement to be untrue or
inaccurate in any material respect at any time from the date hereof to the
Effective Time or (ii) to cause any material covenant, condition or agreement of
any party hereto under this Agreement not to be complied with or satisfied in
all material respects and (b) any failure of any party hereto to comply with or
satisfy any covenant, condition or agreement to be complied with or satisfied by
it hereunder in any material respect; provided, however, that no such
notification shall affect the representations or warranties of any party or the
conditions to the obligations of any party hereunder .

            SECTION 6.10 No Solicitation; Termination Right.

                  (a) Warner agrees that, during the term of this Agreement or,
if sooner, until the date upon which this Agreement is terminated, it shall not,
and shall not authorize or permit any of its Subsidiaries or any of its or its
Subsidiaries' directors, officers, employees, agents or representatives,
directly or indirectly, to solicit, initiate, or furnish or disclose non-public
information in furtherance of, any inquiries or the making of any proposal with
respect to any recapitalization, merger, consolidation or other business
combination involving Warner, or acquisition of any capital (other than upon
exercise of the Options or Warrants which are outstanding as of the date hereof)
or any material portion of the assets (except for acquisition of assets in the
ordinary course of business consistent with past practice) of Warner and its

Subsidiaries, or any combination of the foregoing (a "Competing Transaction"),
or negotiate, or otherwise engage in discussions with any person (other than
Galen or their respective directors, officers, employees, agents and
representatives) with respect to any Competing Transaction or enter into any
agreement, arrangement or understanding requiring it to abandon, terminate or
fail to consummate the Acquisition or any other transactions contemplated by
this Agreement; provided, that prior to the hearing of the Petition, and having
complied with Section 6.10(b) hereof, Warner may furnish information to, and
negotiate or otherwise engage in discussions with, any party who initiates
contact with Warner regarding a Competing Transaction if and so long as the
Board of Directors of Warner determines in good faith, after being advised as to
legal matters by its outside counsel and as to financial matters from its
independent financial adviser, that failing to consider and cooperate with such
other party regarding such Competing Transaction would be likely to constitute a
breach of the fiduciary duties of the Board under applicable law.

                  (b) Warner shall, and shall cause its Subsidiaries, directors,
officers, employees, agents and representatives immediately to cease all
existing activities, discussions and negotiations with any parties conducted
heretofore with respect to any Competing Transaction. Warner agrees that neither
the Board of Directors nor any committee thereof will, during the period
referenced in the first sentence of Subsection (a), (A) withdraw or modify, or
propose publicly to withdraw or modify, in a manner adverse to Galen, the Warner
Board Recommendation, or (B) approve or recommend, or propose publicly to
approve or recommend, any Competing Transaction, unless the Board of Directors
of Warner (after being advised as referred to in Section 6.10(a) hereof)
determines in good faith that failure to do so would be likely to result in
breach of its fiduciary duties under applicable law. During the period
referenced in the first sentence of Subsection (a), Warner shall immediately
advise Galen orally (so far as is reasonably practicable) and in writing of the
receipt, directly or indirectly, of any inquiries, discussions, negotiations, or
proposals relating to a Competing Transaction, such advice to include the
material terms and details thereof (so far as then known to Warner), provided
that, for the avoidance of doubt, Warner shall not be obliged to disclose the
identity of any third party involved in any such possible Competing Transaction
unless and until notice is given by Warner pursuant to sub-section (d) of this
Section 6.10 of an intention to take any action referred to in (A) or (B) above
in connection with such Competing Proposal. Warner will keep Galen reasonably
informed of the status and details (including amendments or proposed
amendments)of any such inquiries, discussions, negotiations or proposals
relating to a Competing Transaction.

                  (c) Notwithstanding the foregoing, in the event that the
Warner Board receives a proposal for a Competing Transaction that it determines
in good faith is reasonably capable of being completed, taking into account all
legal, financial, regulatory and other aspects of the proposal and which would,
if completed, result in a transaction (involving at least 50% of the Warner
Shares in issue and/or 50% of the assets of Warner and its Subsidiaries as the
case may be) which is determined by a majority of the members of the Warner
Board (being, where relevant, a majority of those members who shall be
disinterested in the proposal), in good faith (after receiving advice from
Warner's independent financial adviser that the proposal for a


                                       42
<PAGE>   45
Competing Transaction is more favorable to the Warner Shareholders, from a
financial point of view, than the Scheme and the Transactions), to be more
favorable to Warner Shareholders than the Scheme and the Transactions (a
"Superior Proposal"), the Warner Board may terminate this Agreement pursuant to
Section 8.01(e)hereof and may take any of the actions described in sub-section
(A) and (B) in Section 6.10(b) above in relation to the Superior Proposal and
enter into a letter of intent, agreement-in-principle, acquisition agreement or
other similar agreement, but in any case only after complying with the
provisions of sub-section (d) below.

                  (d) At such time as Warner intends to take any action as set
forth in Section 6.10(b) (A) or (B) in relation to a Superior Proposal, Warner
shall provide to Galen written notice advising Galen that the Warner Board is
prepared to accept a Superior Proposal, specifying the material terms and
conditions of such Superior Proposal and identifying the person making such
Superior Proposal and confirming that such proposal is capable of creating a
legally binding agreement upon Termination of this Agreement. Until the expiry
of a period of five Business Days following receipt of such written notice (the
"Period of First Refusal") or, if earlier, until receipt of a Refusal Notice,
Warner hereby undertakes not to proceed in any way with the Superior Proposal,
including taking any action as set out in clause 6.10(b)(A) or (B) above. During
this period, Galen shall be able to (A) present in writing to Warner a revised
proposal (capable of creating a legally binding amendment to this Agreement upon
acceptance by Warner within the Period of First Refusal) to continue with the
Acquisition (the "Revised Proposal") or (B) present in writing to Warner notice
that Galen does not intend to revise the current proposals as set out in this
Agreement in response to notice of such Superior Proposal (the "Refusal
Notice"). On receipt of the Revised Proposal Warner shall procure that a meeting
of the Warner Board shall consider the terms thereof. In the event that the
Revised Proposal is determined by a majority of the members of the Warner Board
(being, where relevant, a majority of such members who shall be disinterested in
the Superior Proposal) in good faith (after receiving advice from Warner's
independent financial adviser that the Revised Proposal is more favorable to
Warner Shareholders, from a financial point of view, than the Superior Proposal)
to be more favorable to Warner's shareholders than the Superior Proposal, taking
into account all legal, financial, regulatory and other aspects of the proposal,
Warner undertakes to and to procure that its subsidiaries, directors, officers,
employees, agents and representatives shall cease all existing activities,
discussions and negotiations with any party with respect to the Superior
Proposal ) save that the provisions of this Section 6.10 shall apply ab initio
in relation to any proposed amendment to such Superior Proposal). Otherwise, (x)
in the event that the Revised Proposal is determined (on the same bases as
stated in the previous sentence) by the Warner Board to be less favorable than
the Superior Proposal, or (y) in the event that a Refusal Notice is served on
Warner, or (z) on the expiry of the Period of First Refusal without service of a
Revised Proposal or a Refusal Notice, Warner shall be entitled to terminate this
agreement as provided by Section 6.10(c) above and to proceed with any such
actions as set forth in clause 6.10(b)(A) and (B) above.

            SECTION 6.11 Termination of Scheme. Galen hereby covenants and
agrees that in the event that this Agreement is terminated, Galen will provide
all such reasonable cooperation to Warner in relation to any steps reasonably
necessary to or appropriate in


                                       43

                   (a) If the Irish Takeover Panel Act, 1997 (Takeover) Rules,
1997 or any other takeover statute ("Takeover Statute") shall become applicable
to the transactions contemplated hereby, Warner and Galen and the members of
their respective Boards of Directors of Warner, subject to their respective
fiduciary duties, shall grant such approvals and take such actions as are
necessary so that the transactions contemplated hereby may be consummated as
promptly as practicable on the terms contemplated hereby (which shall include
the provision by Warner and its directors and officers of all suitable
assistance and information which may be necessary to or reasonably requested by
Galen in connection with the preparation of any offer document required to be
published by the Irish Takeover Panel, which shall be given in a prompt fashion)
and otherwise act to eliminate or minimize the effects of such Takeover Statute
on the transactions contemplated hereby.

                  (b) Galen shall ensure that Warner shall have access to
sufficient funds which may be required pursuant to any rights of the holders of
Warner's outstanding 12 5/8% Senior Notes due 2008 (the "Notes") triggered by
the entering into by Warner of the Transactions and, to the extent required by
the terms of the Notes, will, with effect from the Effective Time, comply, or
cause Warner to comply, in all respects with Warner's obligations under the
indenture governing the Notes.

                  (c) Galen shall use its reasonable best efforts to cause the
Galen ADSs to be listed for trading on Nasdaq at the Effective Time.

                  (d) Prior to the Effective Time Galen shall procure the
adoption of a new share option scheme for the benefit of US employees on terms
mutually acceptable to it and Warner (in each case acting reasonably) which
scheme shall have due regard to the requirements of both US and UK law,
regulation, custom and practice.

Scheme and the Transactions may be abandoned at any time prior to the making of
the Final Court Order:

                  (a) by the mutual written consent of Galen and Warner;

                  (b) by Warner or Galen pursuant to the relevant provisions of
this Section 8.01, provided, however, that neither Warner or Galen may terminate
this Agreement pursuant to this Section 8.01 if such party shall have materially
breached this Agreement.

                  (c) by Galen or Warner if any court or other Governmental
Entity shall have issued, enacted, entered, promulgated or enforced any order,
judgment, decree, injunction, or ruling or taken any other action restraining,
enjoining or otherwise prohibiting the Transactions and such order, judgment,
decree, injunction, ruling or other action shall have become final and
nonappealable; provided, that the party seeking to terminate the Agreement shall
have used its reasonable best efforts to remove or lift such order, decree or
ruling;

                  (d) by Galen if the Warner Board shall have withdrawn or
modified in a manner adverse to Galen, or refrained from making the Warner Board
Recommendation, or shall have publicly disclosed its intention to change such
recommendation, unless Warner is at such time entitled to terminate this
Agreement pursuant to any of sub-sections (e),(f), or (k) of this Section 8.01;

                  (e) by Warner, pursuant to and in accordance with Section
6.10(c) and (d);

                  (f) by Warner in the event of any breach of the covenants
and/or representations and warranties of Galen contained in this Agreement which
has a Material Adverse Effect on Galen (and for this purpose a breach of
representation/warranty shall be regarded as having a Material Adverse Effect on
Galen if the actual state of affairs, when compared to the position as
represented/warranted, amounts to a change having such a Material Adverse
Effect) ;

                  (g) by Warner if the Galen Shareholder Approval has not been
obtained on or prior to October 31, 2000;


                                       48
<PAGE>   51
                  (h) by Warner if the Galen Board shall have withdrawn or
modified in a manner adverse to Warner, or refrained from making the Galen Board
Recommendation, or shall have publicly disclosed its intention to change such
recommendation, unless Galen is at such time entitled to terminate this
Agreement pursuant to any of sub-sections (i), (j)or (l) of this Section 8.01;

                  (i) by Galen in the event of any breach of the covenants
and/or representations and warranties of Warner contained in this Agreement
which has a material adverse effect on Warner (and for this purpose a breach of
representation/warranty shall be regarded as having a Material Adverse Effect on
Warner if the actual state of affairs, when compared to the position as
represented/warranted, amounts to a change having such a Material Adverse
Effect);

                  (j) by Galen if the Warner Shareholder approval as referred to
in Section 7.01 (f) (i) and (ii) has not occurred on or prior to October 31,
2000;

                  (k) by Warner if (otherwise than as referred to in sub-section
(f) of this Section 8.01), there shall have occurred a change, condition, event
or development that would constitute a Material Adverse Effect on Galen;

                  (l) by Galen if (otherwise than as referred to in sub-section
(i) of this Section 8.01), there shall have occurred a change, condition, event
or development that would constitute a Material Adverse Effect on Warner; and

                  (m) by Warner if CSFB shall have withdrawn its written
fairness opinion referred to in Section 1.01(d) hereof.


In the event that the Scheme does not become effective as a result of a failure
of any of the conditions set forth in Article VII hereof to be satisfied or
(where applicable) waived, within the time provided by Article VII, this
Agreement shall terminate automatically. For the avoidance of doubt, if this
Agreement terminates pursuant to this provision due to non-satisfaction or
(where applicable) waiver of the Galen Shareholder approval condition set forth
in Section 7.01(c) (unless Galen is at the time entitled to terminate this
Agreement pursuant to any of sub-sections 8.01(i) or (l)), or the Warner
Shareholder approval conditions set forth in Section 7.01(f)(i) and (ii) (unless
Warner is at the time entitled to terminate this Agreement pursuant to
sub-section 8.01(f) or (k)), such termination shall be treated in the same
manner as if notice of termination had been given pursuant to Section 8.01(g) or
(j), as the case may be and the corresponding provisions of Section 8.02(c) or,
as the case may be, (e) shall apply accordingly.


            SECTION 8.02 Effect of Termination; Fees and Expenses.

                  (a) In the event of the termination of this Agreement pursuant
to


                                       49
<PAGE>   52
Section 8.01, this Agreement shall forthwith become void and have no effect
without any liability on the part of any party or its directors, officers or
shareholders, other than as provided by this Section 8.02 and Sections 6.06,
8.03 and 8.04 and Articles IX and X, which shall survive any such termination.
In the event of such termination, the provisions of this Section 8.02 shall
constitute the sole and exclusive remedies of the parties, provided always that
nothing contained in this Section 8.02 shall relieve any party from liability
for any breach of this Agreement or the Confidentiality Agreement. Following
such termination the sole remedy for breach of this Agreement (other than
Section 6.06) shall lie in damages, provided that if it shall be judicially
determined that termination of this Agreement was caused by an intentional
breach of this Agreement, then in addition to damages for such breach, the party
so found to have intentionally breached this Agreement shall indemnify and hold
harmless the other party for its respective costs, fees and expenses of its
counsel, accountants, financial advisers and other experts and advisers incident
to negotiation and preparation of this Agreement.

                  (b) The prevailing party in any legal action undertaken to
enforce this Agreement or any provision hereof shall be entitled to recover from
the other party the costs and expenses (including attorneys' and expert witness
fees) incurred in connection with such action.

                  (c) Notwithstanding any provision in this Agreement to the
contrary, if this Agreement terminates pursuant to Section 8.01(d), (e), or
(unless Warner is at the time entitled to terminate this Agreement pursuant to
sub-section (f) or (k) of Section 8.01) (m), Warner shall pay to Galen on demand
a sum equivalent to the reasonable and documented costs and expenses incurred by
Galen in connection with this Agreement and all matters provided for or referred
to herein, including but not limited to the fees and expenses of its lawyers and
merchant banking advisors and any value added tax or similar tax on any such
costs and expenses (which shall include any fees payable in respect of the
facility arrangement put in place by Galen prior to the date of this Agreement
pursuant to its obligations under section 6.13(c) of this Agreement), provided
that the aggregate amount payable pursuant to this Section 8.02(c) shall not
exceed US$4.25 million. The provisions of this sub-section (c) shall also apply
if this Agreement terminates pursuant to Section 8.01(j) (unless, the average of
the closing middle market prices for one Galen Share as reflected by the London
Stock Exchange Daily Official List for the three Business Days prior to the date
of the Court Meeting and the Warner EGM (or the later of the two if different)

commences a suit or takes other action which results in a judgment or other
binding determination against such party for the fees and expenses in Sections
8.02(c) or 8.02(e) hereof or the Termination Fee, the non-paying party shall
also pay to the party entitled to receive payment thereunder (as the case may

[WARNER CHILCOTT LETTERHEAD]

                                                                    NEWS RELEASE


Dublin, Ireland                                                      May 4, 2000
Rockaway, NJ

                GALEN HOLDINGS PLC TO ACQUIRE WARNER CHILCOTT PLC
                             NASDAQ LISTING OF GALEN
    BUILDING AN INTERNATIONAL SPECIALTY PHARMACEUTICAL PRODUCTS AND SERVICES
                                    BUSINESS

May 4, 2000...The Boards of Warner Chilcott (Nasdaq:WCRX) and Galen (LSE:GAL)
announce today that they have entered into an agreement (the "Transaction
Agreement") under which Warner Chilcott will become a wholly owned subsidiary of
Galen. The acquisition is to be effected by way of a scheme of arrangement to be
proposed to Warner Chilcott shareholders (the "Scheme"). The Scheme is subject
to sanction by the High Court of Ireland.

Under the Transaction Agreement, Galen proposes to issue 2.5 new Galen shares
for each Warner Chilcott share (equivalent to 2.5 Galen shares for each Warner
Chilcott ADS) pursuant to the terms of the Scheme. The proposed acquisition of
Warner Chilcott in consideration for new Galen shares (the "Transaction") is
expected to be tax free to Warner Chilcott's US, UK and Republic of Ireland
shareholders and ADS holders.


Galen will seek the listing of the new Galen shares on Nasdaq in American
Depositary Share ("ADS") form.


Based on the closing mid-market price per Galen share of 612.5p ($9.58) on May
3, 2000, the terms of the Transaction value each Warner Chilcott share at $23.94
(1,531.3p) and the total current issued share capital of Warner Chilcott at
approximately $296.5 million ((pound sterling) 189.6 million) (or $406.3 million
((pound sterling) 259.9 million) on a fully diluted basis). The terms of the
Transaction represent a premium of 33.0 % over the closing price of $18.00 per
Warner Chilcott ADS on Nasdaq on May 3, 2000 and a premium of 57.0 % over the
average closing price of a Warner Chilcott ADS for the last 30 business days
ended 3rd May, 2000.


The scheme will require the approval of Warner Chilcott shareholders. Due to the
size of the Transaction, Galen will seek the approval of its shareholders at an
EGM. Subject to appropriate regulatory clearances in the US, Republic of Ireland
and UK, it is currently the intention of Warner Chilcott and Galen to send the
relevant documentation to their respective shareholders in July 2000. The Scheme
is currently expected to become effective and the Transaction to complete by the
end of August 2000.

Credit Suisse First Boston served as financial adviser to Warner Chilcott in
this transaction and Merrill Lynch served as financial adviser to Galen. Hoare
Govett Limited are sole UK and European broker to Galen, Goodbody Stockbrokers
are broker to Galen in Ireland and Merrill Lynch are broker to Galen in the US.

Merger Will Create a Fully Integrated, International Pharmaceutical Company

The Transaction will create a significant international specialty pharmaceutical
products and services group with combined pro forma revenues of $233.2 million
((pound sterling) 143.1 million), with a sales force of approximately 260
servicing the US and approximately 65 servicing the UK and Ireland. Based on the
closing mid-market price per Galen share of (pound sterling) 612.5p ($9.58) on
May 3, 2000, the pro forma combined market capitalization of the combined group
would be approximately $1.5 billion ((pound sterling) 969.1 million).

Major benefits of the combination include:

     -    Strengthened women's healthcare portfolio. The combined entity will
          benefit from the combination of Galen's pipeline of proprietary
          women's healthcare products and Warner Chilcott's women's healthcare
          focused sales and marketing organization in the US. In particular, the
          transaction will enable Galen both to commercialize its intravaginal
          ring drug delivery system ("IVR"), and, by retaining the distribution
          margin, to achieve a greater economic stake in any future success of
          products using the IVR platform technology. The strength of Warner
          Chilcott's US sales and marketing organization will be improved by
          Galen's pipeline of proprietary products, enhanced product development
          capability and current GMP (good manufacturing practice) manufacturing
          capacity.

     -    Greater opportunities for growth and acquisitions. With its greater
          scale and profitability, the combined entity expects to pursue
          acquisitions both in the UK and the US as well as to seek selective
          in-licensing opportunities from the pharmaceutical industry.

     -    An international management team with extensive pharmaceutical
          expertise. The executive management of the combined entity, which will
          be continue to be called Galen Holdings PLC, will consist of two
          members each from Galen and Warner Chilcott. Dr. John King will be
          Chairman of the Board, Roger Boissonneault will be Chief Executive
          Officer, Geoffrey Elliott will be Chief Financial Officer and Paul
          Herendeen will be Executive Vice President and Director of Business
          Development. All four executives will serve on the Board of Directors.

     -    Increased investor profile and enhanced liquidity. The combined entity
          will have listings in London, Dublin and Nasdaq and will offer
          investors an opportunity to invest in a larger company with a growing
          international presence and geographical reach.

Commenting, Roger Boissonneault, President and Chief Operating Officer of Warner
Chilcott, said:

"The most exciting element of this transaction is the opportunity to combine the
complementary strengths of our management teams. With the scale to be
competitive in segments of both the UK and the US markets we will have access to
a broad range of initiatives and the strength to capitalize on those we choose
to pursue. Warner Chilcott's Board of Directors is unanimous in its support for
the Offer and believes that it is in the best interests of Warner Chilcott
shareholders, customers and employees. Our entire senior management team is
looking forward to developing the business as a combined entity."

Commenting on the Offer, Dr. John King, Chief Executive Officer of Galen, said:

"This transaction is a major step in internationalizing the Galen business and
provides Galen with immediate product marketing and distribution strength in the
US, the world's largest pharmaceutical market. The combination will allow us to
geographically expand the distribution of our women's healthcare portfolio,
including our IVR product, within Galen without having to give away value from
out-licensing deals. The enlarged group will have a larger therapeutic and
geographic base with significant combined sales forces in the US, UK and Ireland
providing a strong platform to take the enlarged business forward."

Galen Holdings, PLC

Galen is an integrated pharmaceutical company, based in Northern Ireland. The
company was founded in 1968 and was listed on the London Stock Exchange in 1997.
Galen develops and manufactures branded prescription pharmaceutical products,
which are promoted by its 65 person sales and marketing organisation in the
United Kingdom and Ireland. Galen's Ethical Pharmaceutical Services division
supplies and distributes clinical trial materials internationally, operates a
drug reconciliation business and uses computer-based interactive voice response
systems to permit the more efficient management of the clinical trial process.
The Services division also provides a 'bench-to-pilot-scale' specialist chemical
synthesis service for the research-based pharmaceutical industry through its
SynGal and QuChem units. In 1997, Galen opened its first pharmaceutical services
facility in the United States to meet the needs of a global marketplace.

Galen's research and development activity focuses on the development of
proprietary drug delivery applications and technologies. Galen has a solid
pipeline of proprietary products in development for the women's healthcare
market including an intravaginal ring drug delivery system (IVR) that is
designed to deliver a consistent dose of a wide range of medicines over extended
periods of time.

The company has lodged its first marketing authorization application in the UK,
for the estradiol-based IVR for hormone replacement therapy (HRT), and
anticipates the UK launch of the product during the second half of 2000, with
the European launch expected to follow in late 2001. Galen is also targeting a
US NDA application for late 2000. A phase III trial for the estradiol/progestin
IVR for continuous combined HRT is planned for the current financial year, with
anticipated marketing authorization applications in the US and UK during 2002,
with Europe one year later. Galen has also developed proprietary topical drug
delivery technology based on the improved skin penetrating properties of
eutectic mixtures of pharmacologically active agents.

Galen has an impressive track record of profitable growth generated both
organically and through acquisition. Since 1995 revenues have nearly tripled
from (pound sterling) 23.3 million to (pound sterling) 67.0 million ($36.9
million to $109.2 million) while profit before taxation and exceptional items
increased five-fold from (pound sterling) 3.6 million to (pound sterling) 18.4
million ($5.7 million to $30.0 million).

Warner Chilcott, PLC

Warner Chilcott develops and markets branded prescription pharmaceutical
products in the United States, primarily focused on the women's health
therapeutic category. The company was formed in 1992 and its shares became
publicly traded in ADS form on Nasdaq in 1997. Through its national US sales
force of approximately 260 representatives, Warner Chilcott markets branded
pharmaceutical products directly to physician specialists across the US,
particularly obstetrician/gynecologists and urologists. The Company's principal
offices are in Dublin, Ireland and Rockaway, New Jersey. On February 15, 2000,
Warner Chilcott acquired three women's healthcare products from Bristol-Myers
Squibb for a total consideration of $175.1 million. The acquired brands, which
generated nearly $50 million in revenues during 1999, are Estrace(R) vaginal
cream, an estrogen replacement therapy product, and two oral contraceptives,
Ovcon(R) 35 and Ovcon(R) 50.

On a pro forma basis after giving effect to the recent acquisition of the three
branded pharmaceutical products from Bristol-Myers Squibb and the financing
thereof, Warner Chilcott would have had, on a US GAAP basis, total revenues and
income before taxes for the twelve months ended December 31, 1999 of $124.0
million ((pound sterling) 76.1 million) and $4.8 million ((pound sterling) 3.0
million), respectively and would have had net assets as at December 31, 1999 of
$98.3 million ((pound sterling) 60.3 million).
