organized  under the laws of the United States,  having an office located at Two
Tower Center  Boulevard,  East  Brunswick,  New Jersey  08816,  as Agent for the

                              W I T N E S S E T H:

      WHEREAS,  pursuant to a certain  Revolving  Credit and Security  Agreement
dated of even date  herewith by and between  Warner  Chilcott,  Inc., a Delaware
corporation (the  "Borrower"),  PNC Bank,  National  Association and one or more
financial  institutions  named therein or which hereafter become a party thereto
(together with PNC Bank, National Association,  collectively, the "Lenders") and
PNC Bank, National  Association as the agent for the Lenders (PNC Bank, National
Association in such capacity,  the "Agent") (as such may be amended from time to
time, the "Loan  Agreement"),  the Lenders have agreed to make certain Revolving
Advances to the Borrower; and

      WHEREAS,  as a condition precedent to the making of the Revolving Advances
by the Lenders to the  Borrower,  Warner has agreed to  financially  support the
operations  of  the  Borrower  in  accordance   with  the   provisions  of  this
Undertaking; and

      WHEREAS,  the  Borrower  is a wholly  owned  subsidiary  of Warner PLC and
Warner  PLC  and  Warner  Bermuda  will  derive   benefits  from  the  financial
accommodations  being accorded the Borrower by the Lenders pursuant to the terms
of the Loan Agreement.

      NOW,  THEREFORE,  in  consideration of the premises and in order to induce
the Lenders to make and/or continue to make the Revolving Advances (as each such
term is defined in the Loan  Agreement),  and in  consideration of the Revolving
Advances made pursuant to the terms of the Loan  Agreement and Other  Documents,
and to enable  the  Revolving  Advances  to be  maintained  or  obtained  by the
Borrower  under the terms of the Loan  Agreement,  Warner hereby agrees with the
Lenders as follows:

            1. Warner shall,  on a consolidated  basis  (exclusive of Borrower's
      accounts), establish and maintain during the term of the Loan Agreement, a
      balance in an amount of not less than $15,000,000  consisting of unpledged
      and  unencumbered   cash  and  cash  equivalents  in  form  and  substance
      reasonably satisfactory to the Lenders. Warner will provide to the Lenders
      from time to time, at the request of the Lenders, evidence satisfactory to
      the  Lenders  that  such  balance  has  been   established  and  is  being
      maintained.

            2. Warner shall monitor the financial  condition of the Borrower and
      provide the  Borrower  with  sufficient  funds to ensure that the Borrower
      maintains,  at all times, Undrawn Availability as determined by the Agent,
      of not less than $1,500,000.  In the event that Agent determines that such
      Undrawn  Availability  is  less  than  $1,500,000  and so  advises  Warner
      pursuant to Section 9 hereof,  Warner  shall,  within five (5) days of the
      sending of notice,  provide the Borrower with sufficient funds to maintain
      Undrawn Availability of $1,500,000.

            3. In addition to and independent of its other obligations described
      herein,  including, but not limited to those set forth in paragraphs 1 and
      2 above,  in the event the Borrower  suffers  Cash Losses (as  hereinafter
      defined) based upon the Quarterly Financial  Statements to be delivered to
      the Lenders by the Borrower pursuant to Section 9.8 of the Loan Agreement,
      Warner shall, on a quarterly basis and within three (3) days of receipt of



      notice from the Lenders,  provide the Borrower by wire  transfer with cash
      funds in an amount equal to: (a) Fifty  percent  (50%) of such Cash Losses
      with  respect to the first  $7,000,000  of actual  cumulative  Cash Losses
      incurred from the date hereof;  and (b) One Hundred  percent (100%) of all
      Cash  Losses  incurred  in  excess of  $7,000,000,  less  amounts  of cash
      provided by Warner to the Borrower during the applicable quarterly period.
      For the purposes hereof,  the term "Cash Losses" shall mean and be defined
      as  Borrower's  net losses (or income)  after  taxes,  plus  depreciation,
      amortization and non-cash interest  expense,  less all non-cash income and
      less all distributions permitted under the Loan Agreement.

            4. All cash funds provided by Warner  pursuant to clauses 2 and 3 of
      this  Agreement  shall be  contributed to the Borrower as either equity or
      subordinated  debt in form and substance  reasonably  satisfactory  to the
      Agent and shall be deposited in Borrower's  account at the Agent,  Account
      #8008995934.  All such cash funds provided by Warner pursuant to clauses 2
      and 3 of this Undertaking shall remain with Borrower and may not be repaid
      or otherwise  returned to Warner as long as the Loan Agreement  remains in
      effect and any Obligations of Borrower remain outstanding.

            5.  Warner PLC shall  provide to the Agent  within  thirty (30) days
      after  the end of each of  Warner  PLC's  fiscal  quarters,  Warner  PLC's
      financial  statements  in form and  substance  satisfactory  to the Agent,
      together with all documentation  submitted by Warner PLC to the Securities
      and Exchange Commission, including all Form 20Fs, as well as a Certificate
      by the Chief Financial  Officer of Warner  certifying as to all cash funds
      contributed by Warner to the Borrower,  as well as  specifically:  (a) all
      cash funds delivered to the Borrower  pursuant to the terms hereof and (b)
      all cash  funds  returned  to Warner by  Borrower  other than cash paid to
      Warner for goods and services provided.

            6.  The  failure  of  Warner  to  comply  with  any of the  terms or
      conditions  contained herein shall be deemed an Event of Default under the
      Loan Agreement.

            7. This  Undertaking is a continuing  Undertaking  and nothing shall
      terminate,  discharge or satisfy the liability of Warner  hereunder  until
      the Obligations of the Borrower have been satisfied in full.

            8. The Lenders  may,  in their  reasonable  discretion,  enforce the
      Obligations  of Warner as  contained  herein  and  exercise  any rights or
      remedies which the Lenders may have by law (such rights and remedies being
      cumulative  and  not  alternative  or  exclusive)   without   pursuing  or
      exhausting  any rights or remedy the Lenders may have against the Borrower
      or any other  person or entity for which the Lenders  have with respect to
      any  collateral  or any  guaranty or any or all of such  Obligations.  The
      Lenders  need not join the  Borrower  or any  other  person or entity as a
      party in any action  brought to enforce  the  provisions  hereof;  and the
      Lenders  may  exercise  any right or remedy  which  they have  under  this
      Undertaking  without regard to any actions or omissions of the Borrower or
      any other person or entity.

            9. All notices,  requests and other communications  pursuant to this
      Undertaking shall be in writing, to be either delivered by hand, overnight
      delivery,  or sent certified mail, return receipt requested,  addressed to
      the Agent at its  office  located  at Two  Tower  Center  Boulevard,  East
      Brunswick, New Jersey 08816, ATTENTION:  Business Credit Department, or to
      Warner at the address set forth on page 1 of this Undertaking,  or at such
      other  address as either may give notice to the other as herein  provided.
      Any notice,  request or  communication  hereunder  shall be deemed to have
      been given when delivered.  However, and notwithstanding any other term or
      provision contained herein to the contrary, Warner Bermuda hereby appoints
      Warner PLC as its Agent to receive all  service of process  arising out of
      any dispute relating to this Undertaking.

            10. Any capitalized term not otherwise defined herein shall have the
      meaning ascribed thereto in the Loan Agreement.

            11. This  Undertaking  shall be  construed  in  accordance  with and
      governed by the laws of the State of New Jersey.



            12. This  Undertaking  shall be binding upon Warner,  as well as its
      successors  or assigns  and inure to the  benefit of the  Lenders  and the
      Lenders' successors and assigns.

            13. WARNER HEREBY  IRREVOCABLY  CONSENTS TO THE  JURISDICTION OF THE
      COURTS  OF THE  STATE  OF NEW  JERSEY  AND,  TO THE  EXTENT  PERMITTED  BY
      APPLICABLE LAW, OF ANY FEDERAL COURT LOCATED IN THE STATE OF NEW JERSEY IN
      CONNECTION WITH ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THE
      UNDERTAKINGS.  WARNER HEREBY  WAIVES THE DEFENSES OF FORUM NON  CONVENIENS
      AND IMPROPER VENUE.

            14.  WARNER  EXPRESSLY  WAIVES  THE  RIGHT  TO  TRIAL BY JURY IN ANY
      LITIGATION  RELATING  TO,  IN  CONNECTION  WITH,  OR  ARISING  OUT OF THIS
      UNDERTAKING OR ANY OTHER DOCUMENT  DELIVERED IN CONNECTION WITH ANY OF THE
