                           OPTION ROLLOVER AND LOCK-UP
                                    AGREEMENT

         THIS OPTION ROLLOVER AND LOCK-UP AGREEMENT (the "Agreement") is made as
of May 4, 2000, between GALEN HOLDINGS PUBLIC LIMITED COMPANY, a public limited
company organized under the laws of Northern Ireland (the "Company"), and James
Andress ("Executive").

                                    RECITALS

                  WHEREAS, Executive is currently employed by Warner Chilcott
         Public Limited Company ("Warner"); and

                  WHEREAS, Executive holds options to purchase 100,000 shares of
         common stock of Warner (the "WC OPTIONS") pursuant to the Warner
         Chilcott plc Incentive Share Option Scheme (the "WC OPTION SCHEME");
         and

                  WHEREAS, Executive holds warrants to purchase 500,000 shares
         of common stock of Warner, pursuant to certain Warrant Agreements by
         and between Executive and Warner (the "WARRANTS"); and

                  WHEREAS, the Company and Warner have entered into a
         transaction agreement pursuant to which the Company will exchange all
         of the outstanding securities of Warner for ordinary shares in the
         Company pursuant to a scheme of arrangement pursuant to Section 201 of
         the Irish Companies Act (the "ACQUISITION");

                  WHEREAS, pursuant to the terms of the WC Option Scheme and an
         Employment Agreement, dated August 1, 1999 by and between Warner and
         the Executive upon consummation of the Acquisition, the Executive shall
         be fully vested in all WC Options; and

                  WHEREAS, on February 28, 2000 the Executive entered into an
         arrangement with Warner to receive 150,000 options to purchase ordinary
         shares of Warner (the "Pending Options"); and

                  WHEREAS, Executive and the Company have agreed to enter into
         an Severance Agreement dated May 4, 2000 (the "SEVERANCE AGREEMENT") by
         and between the Executive and Warner in relation to the Employment
         Agreement as mentioned above; and

                  WHEREAS, the Company and the Executive mutually desire to
         enter into this Agreement regarding the exercise and treatment of
         Executive's WC Options and the Warrants in connection with the
         Acquisition and the shares of the stock to be acquired upon the
         exercise of the WC Options and the Warrants.

<PAGE>   2

                  NOW, THEREFORE, in consideration of the Severance Agreement
         and the mutual covenants and agreements contained herein, the parties
         agree as follows:

1.       VESTING AND OPTION ROLLOVER.

         (a) Executive and the Company hereby agree that upon the Acquisition
all of the Executive's WC Options and Warrants, to the extent not all ready
vested, shall become fully vested and exercisable.

         (b) Each WC Option and Warrant which is outstanding and unexercised
immediately prior to the effective time of the Acquisition shall cease to
represent a right to acquire shares of Warner common stock ("WC STOCK") and
shall automatically become the right to purchase the number of shares of Company
common stock ("COMPANY STOCK") into which the shares of WC Stock subject to such
WC Option and/or Warrant would have been converted into at the effective time of
the Acquisition (rounded down to the nearest full number of shares of Company
Stock) for an exercise price equal to the result of dividing the per share
exercise price of such WC Option and/or Warrant by the exchange ratio in the
Acquisition (rounded down to the nearest full cent). Except for the adjustments
provided for in this Section 1 the WC Options shall continue to be governed by,
and be subject to, the terms of the WC Option Scheme and agreements pursuant to
which such WC Options and Warrants were granted.

2.       LOCK UP.

         The Executive hereby undertakes that from the date of issue until the
date of publication of the interim financial results of the Company for the six
month period ending 31 March 2001, he shall not exercise or transfer any of the
WC Options and/or Warrants or any such options or warrants over company stock
issued to the Executive pursuant to section 1(b) hereof (the "RESTRICTED
OPTIONS") except with the prior written consent of an independent majority of
the Board of the Company, which such consent will not be unreasonably withheld
or delayed.

         In the event that a Change in Control of Galen occurs prior to the
expiry of this lock-up period, this undertaking shall cease and determine with
immediate effect. For the purposes of this section "Change in Control" shall be
deemed to have occurred if any person (or persons "acting in concert" as defined
in the UK's City Code on Takeovers and Mergers) obtains "control" (as that term
is defined in s.840 of the UK Income and Corporation Taxes Act 1988) of Galen
and that control is unconditional in all respects; but excluding any
reconstruction or amalgamation of Galen.

3.       PENDING OPTIONS.

         Executive hereby waives all right to the Pending Options. In
consideration for such waiver, the Company hereby agrees to grant to Executive
an option to purchase ordinary shares of the Company, as set forth in the
Severance Agreement.

<PAGE>   3

4.       NO CONTRADICTION AND COMPLETE AGREEMENT.

No action taken by the Board of Warner or the compensation committee of that
Board on or after the date of this Agreement in relation to the WC Option Scheme
shall apply to the WC Options, if such action would otherwise contradict with
the provisions of this Agreement and Severance Agreement. This Agreement,
together with any other agreements referred to herein, constitutes the complete
agreement and understanding among the parties and supersedes and preempts any
prior understandings, agreements or representations by or among the parties,
written or oral, which may have related to the subject matter hereof in any way.

5.       NO STRICT CONSTRUCTION. The language used in this Agreement shall be
deemed to be the language chosen by the parties hereto to express their mutual
intent, and no rule of strict construction shall be applied against any party.

6.       COUNTERPARTS.
This Agreement may be executed in separate counterparts, each of which is deemed
to be an original and all of which taken together constitute one and the same
agreement.

7.       SUCCESSORS AND ASSIGNS. This Agreement is intended to bind and inure to
the benefit of and be enforceable by Executive, the Company and their respective
heirs, successors and assigns, except that Executive may not assign his rights
or delegate his obligations hereunder without the prior written consent of the
Company. The Company will require any successor to all or substantially all of
the business and/or assets of the Company to assume expressly and agree to
perform this Agreement in the same manner and to the same extent that the
Company would be required to perform it if no such succession had taken place.

8.       CHOICE OF LAW.
All issues and questions concerning the construction, validity, enforcement and
interpretation of this Agreement and the exhibits and schedules hereto shall be
governed by, and construed in accordance with, the laws of the State of New
Jersey without giving effect to any choice of law or conflict of law rules or
provisions that would cause the application of the laws of any jurisdiction
other than the State of New Jersey.

9.       AMENDMENT AND WAIVER.
The provisions of this Agreement may be amended or waived only with the prior
written consent of the Company and Executive, and no course of conduct or
failure or delay in enforcing the provisions of this Agreement shall affect the
validity, binding effect or enforceability of this Agreement.

10.      TERMINATION. This Agreement shall automatically terminate in the event
the Transaction Agreement is terminated in accordance with its terms.

         IN WITNESS WHEREOF, the parties hereto have executed this Agreement as

J Andress Series C No. W01
Execution Copy

     SUPPLEMENTAL AGREEMENT NO. 1 TO WARNER CHILCOTT PUBLIC LIMITED COMPANY
                               WARRANT CERTIFICATE

            WHEREAS, James Andress (the "Warrant Holder") is the holder of
certain warrants (the "Warrants") of Warner Chilcott Public Limited Company
("WC") as set forth in a certificate numbered SERIES C NO. W01 (the "Warrant
Certificate");

            WHEREAS, on September 29, 2000 WC and Galen Holdings PLC ("Galen"),
consummated a change of control transaction (the "Acquisition") by means of a
scheme of arrangement under the laws of the Republic of Ireland (the "Scheme")
whereby Galen exchanged all of the outstanding securities of WC for ordinary
shares in Galen; and

            WHEREAS, unless otherwise defined herein, capitalized terms used
herein will have the meanings set forth in the Warrant Certificate.

            NOW THEREFORE, the parties agree as follows:

            1. Change in Number and Purchase Price of Warrants. Under the
Scheme, holders of warrants to purchase WC's American Depository Receipts
("ADR's"), evidencing WC's American Depository Shares ("ADS's") will, upon
exercise, receive ordinary shares of Warner Chilcott, each of which will
immediately be exchanged pursuant to the Scheme for 2.5 ordinary shares of
Galen, to be held in the form of Galen ADR's evidencing Galen ADS's. Each Galen
ADS currently represents four Galen ordinary shares. As a result, (a) each
holder of warrants to purchase WC ADR's will, upon such exercise and immediate
exchange, receive 0.625 Galen ADR's for each WC ADR, with fractions of ADR's
being rounded as appropriate, and (b) the effective purchase price for these
Galen ADR's shall be derived by dividing the Purchase Price of WC ADR's by
0.625. Therefore, the Warrant Certificate will hereinafter have the effect of
entitling the Warrant Holder to purchase 250,000 Galen ADR's at a purchase price
of $32.00.

            2. Net Exercise. The following language shall be added to the end of
Section 2(e) of the Warrant Certificate:

            "IN LIEU OF PAYMENT OF THE PURCHASE PRICE AS SET FORTH IN THE FIRST
            SENTENCE OF THIS SECTION 2(e), THE WARRANT HOLDER MAY EXERCISE THIS
            WARRANT BY DELIVERING A NOTICE OF NET EXERCISE IN THE FORM OF
            EXHIBIT A HERETO ELECTING TO RECEIVE, WITHOUT CASH PAYMENT BY THE
            WARRANT HOLDER OF ANY ADDITIONAL CONSIDERATION, ORDINARY SHARES THAT
            WILL IMMEDIATELY BE EXCHANGED FOR GALEN ADR'S EQUAL TO THE VALUE OF
            THE WARRANTS (OR THE PORTION THEREOF BEING CANCELED) BY SURRENDER OF
            THIS WARRANT CERTIFICATE TOGETHER WITH THE FORM OF NET EXERCISE
            (ATTACHED HERETO AS EXHIBIT A) DULY EXECUTED, IN WHICH EVENT THE
            COMPANY SHALL ISSUE TO THE WARRANT HOLDER HEREOF (UPON THE IMMEDIATE
            EXCHANGE OF

            ORDINARY SHARES PURSUANT TO THE SCHEME) A NUMBER GALEN ADR'S
            COMPUTED USING THE FOLLOWING FORMULA:

                                        X= Y (A-B)
                                           -------
                                             A

            WHERE:      X=THE NUMBER OF GALEN ADR'S TO BE ISSUED TO THE
                        WARRANT HOLDER PURSUANT TO THIS NET EXERCISE;

                        Y= THE NUMBER OF GALEN ADR'S IN RESPECT OF WHICH THE
                        NET ISSUE ELECTION IS MADE;

                        A= THE FAIR MARKET VALUE OF ONE GALEN ADR AT THE TIME
                        THE NET ISSUE ELECTION IS MADE; AND

                        B= THE PURCHASE PRICE (AS ADJUSTED TO THE DATE OF THE
                        NET ISSUANCE) DIVIDED BY 0.625.

            FOR PURPOSES OF THIS SECTION 2(e), THE FAIR MARKET VALUE OF ONE
            GALEN ADR AS OF A PARTICULAR DATE SHALL BE DETERMINED BY USING THE
            AVERAGE OF THE CLOSING PRICES OF THE GALEN ADR'S TRADED ON THE
            NASDAQ NATIONAL MARKET (OR ANY SUCCESSOR UNITED STATES NATIONAL
            MARKET THE GALEN ADR'S TRADE ON) OVER THE TWENTY (20) DAY PERIOD
            ENDING THREE (3) DAYS PRIOR TO THE NET EXERCISE ELECTION."

            3. Deposit Agreement. The reference to "Deposit Agreement" in
Section 3 of the Warrant Certificate shall be amended so that it refers instead
to the Amended and Restated Deposit Agreement among WC, Galen and The Bank of
New York as Depositary, dated September 29, 2000.
