TRADEMARK COLLATERAL ASSIGNMENT AND SECURITY AGREEMENT

      THIS TRADEMARK COLLATERAL ASSIGNMENT AND SECURITY AGREEMENT is made on the
30th day of March, 1998 between WARNER CHILCOTT (BERMUDA)  LIMITED,  an exempted
company incorporated under the laws of Bermuda having an address at P. O. Box HM
1022, Hamilton HMDX Bermuda  ("Assignor"),  and PNC BANK,  NATIONAL  ASSOCIATION
having an office at Two Tower Center, East Brunswick, New Jersey 08816, as Agent
for the  Lenders  under  the Loan  Agreement  (as  such  terms  are  hereinafter
defined).

      BACKGROUND.  Assignor has executed and delivered on even date herewith its
Continuing Limited Non-Recourse and Collateralized  Guaranty (the "Guaranty") to
the Lenders  guarantying  the Obligations of WARNER  CHILCOTT,  INC., a Delaware
corporation  (the  "Borrower"),  pursuant  to the terms of a  certain  Revolving
Credit and  Security  Agreement  dated of even date  herewith by and between 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").  In order to induce the  Lenders to execute  and  deliver  the Loan
Agreement,  Assignor has agreed to  collaterally  assign to the Lenders  certain
trademark rights.  This Agreement is being executed  contemporaneously  with the
Loan Agreement  under which the Lenders are being granted a lien on and security
interest in accounts receivable,  inventory,  equipment and certain other assets
("Other Assets") relating to products sold under the Trademarks (as such term is
defined in paragraph 1) whereby the Lenders shall have the right to foreclose on
the  Trademarks  and  the  Other  Assets  in the  event  of the  occurrence  and
continuance  of an Event of  Default  (as such  terms  are  defined  in the Loan
Agreement),  in order that the Lenders or any subsequent owner of the Trademarks
may continue to use the Trademarks in  substantially  the same manner as used by
Assignor or Borrower.

      NOW, THEREFORE,  in consideration of the premises,  Assignor hereby agrees
with the Lenders as follows:

            1. To secure the complete and timely satisfaction of all Obligations
      (as such term is defined in the Loan Agreement) and the liabilities of the
      Assignor  pursuant to the Guaranty,  Assignor  hereby grants,  assigns and
      conveys to the Lenders the Assignor's entire right,  title and interest in
      and to the  trademark  applications  and  trademarks  listed in Schedule A
      hereto (as the same may be  amended  pursuant  hereto  from time to time),
      including  without  limitation  all  renewals  thereof,  all  proceeds  of
      infringement  suits,  the  right  to sue  for  past,  present  and  future
      infringements and all rights  corresponding  thereto  throughout the world
      (all of the foregoing are collectively  called the "Trademarks"),  and the
      goodwill of the business to which each of the Trademarks relates.

            2. Assignor covenants and warrants that to the best of its knowledge
      (actual or constructive):

            (a)   The  Trademarks  are  subsisting  and have  not been  adjudged
                  invalid or unenforceable;

            (b)   Each of the Trademarks is valid and enforceable;

            (c)   No claim has been  made that the use of any of the  Trademarks
                  does or may violate the rights of any third person;



            (d)   Assignor  is the sole and  exclusive  owner of the  entire and
                  unencumbered  right,  title and interest in and to each of the
                  Trademarks,   free  and  clear  of  any  liens,   charges  and
                  encumbrances,    including   without    limitation    pledges,
                  assignments,   licenses,   registered   user   agreements  and
                  covenants by Assignor not to sue third persons, other than the
                  assignment to the Lenders pursuant to this Agreement;

            (e)   Assignor  has  the  unqualified   right  to  enter  into  this
                  Agreement and perform its terms;

            (f)   Assignor has used,  and will  continue to use for the duration
                  of this Agreement,  proper statutory notice in connection with
                  its use of the Trademarks;

            (g)   Assignor has used,  and will  continue to use for the duration
                  of this  Agreement,  consistent  standards  of  quality in its
                  manufacture or use of products sold under the Trademarks; and

            (h)   Assignor  (along with its  predecessors  in interest) does not
                  own any other Trademarks and/or patents,  trade names, service
                  marks or other intangible assets which are registered with the
                  United States Patent and Trademark Office in Washington, D.C.

            3.  Assignor  hereby  grants to the  Lenders and its  employees  and
      agents upon  reasonable  notice the right to visit  Assignor's  facilities
      which maintain or store products sold under any of the Trademarks,  and to
      inspect  the  products  and  quality  control  records  relating  thereto.
      Assignor shall do any and all acts  reasonably  required by the Lenders to
      ensure Assignor's compliance with paragraph 2(g).

            4. Assignor  agrees that,  until all of the  Obligations  shall have
      been satisfied in full, it will not enter into any agreement (for example,
      a license  agreement)  which is inconsistent  with Assignor's  obligations
      under this  Agreement,  without the Lenders' prior written  consent,  such
      consent not to be unreasonably withheld.

            5. If,  before the  Obligations  shall have been  satisfied in full,
      Assignor   shall  obtain  rights  to  any  new   trademarks  or  trademark
      applications  the  provisions  of  paragraph 1 shall  automatically  apply
      thereto and Assignor shall give the Lenders prompt written notice thereof.

            6.  Assignor  authorizes  the  Lenders to modify this  Agreement  by
      amending  Schedule  A to  include  any  future  trademarks  and  trademark
      applications covered by paragraphs 1 and 5.

            7. Unless and until  there shall have  occurred an Event of Default,
      the Lenders hereby grant to Assignor the exclusive,  nontransferable right
      and license to use the Trademarks on and in connection  with products sold
      by Assignor or Borrower,  for  Assignor's  own benefit and account and for
      none  other.  Assignor  agrees not to sell or assign its  interest  in, or
      grant any  sublicense  under,  the  license  granted to  Assignor  in this
      paragraph  7,  without  the prior  written  consent of the  Lenders  which
      consent shall not be unreasonably withheld.

            8. If any Event of Default shall have occurred,  Assignor's  license
      under  the  Trademarks,  as set  forth in  paragraph  7,  shall  terminate
      forthwith, and the Lenders shall have, in addition to all other rights and
      remedies  given to them by this  Agreement and the Loan  Agreement,  those
      rights  and  remedies  allowed by law and the  rights  and  remedies  of a
      secured  party  under  the  Uniform  Commercial  Code  as  enacted  in any
      jurisdiction in which the Trademarks may be located and,  without limiting
      the  generality of the  foregoing,  the Lenders may  immediately,  without
      demand of  performance  and without other notice (except as set forth next
      below) or demand whatsoever to Assignor, all of which are hereby expressly
      waived,  and  without  advertisement,  sell at public or  private  sale or
      otherwise realize upon in a commercially  reasonable  manner,  all



      or from  time to time any of the  Trademarks,  or any  interest  which the
      Assignor may have therein,  and after  deducting from the proceeds of sale
      or other disposition of the Trademarks all reasonable  expenses (including
      all reasonable  expenses for broker's fees and legal services),  may apply
      the  residue  of such  proceeds  to the  payment of the  Obligations.  Any
      remainder of the proceeds after payment in full of the  Obligations  shall
      be paid over to the Assignor.  Notice of any sale or other  disposition of
      the Trademarks  shall be given to Assignor at least five (5) Business Days
      (as such term is  defined  in the Loan  Agreement)  before the time of any
      intended public or private sale or other  disposition of the Trademarks is
      to be made, which notice Assignor hereby agrees shall be reasonable notice
      of such sale or other disposition.  At any such sale or other disposition,
      the  Lenders  or the  holder  of any of the  notes  or  other  instruments
      evidencing the Obligations may, to the extent permissible under applicable
      law,  purchase the whole or any part of the Trademarks sold, free from any
      right or equity of  redemption  on the part of  Assignor,  which right and
      equity of redemption are hereby waived and released.

            9. At such time as  Borrower  shall  completely  satisfy  all of the
      Obligations,  this Agreement shall terminate and the Lenders shall execute
      and deliver to Assignor at Assignor's  expense all deeds,  assignments and
      other  instruments  as may be  necessary  or proper to re-vest in Assignor
      full title to the Trademarks, subject to any disposition thereof which may
      have been made by the Lenders pursuant hereto.

            10. Any and all  reasonable  fees,  costs and expenses,  of whatever
      kind or nature,  including  reasonable  attorney  fees and legal  expenses
      incurred  by the  Lenders  in  connection  with  the  preparation  of this
      Agreement and all other documents  relating hereto and the consummation of
      this transaction,  the filing or recording of any documents (including all
      taxes in connection therewith) in public offices, the payment or discharge
      of any taxes,  counsel fees,  maintenance fees,  encumbrances or otherwise
      protecting,  maintaining  or preserving  the  Trademarks,  in defending or
      prosecuting  any actions or  proceedings  arising out of or related to the
      Trademarks,  or in the  enforcement by the Lenders of any of its rights or
      remedies  under this  Agreement,  the Guaranty,  the Loan Agreement or any
      Other  Document (as such term is defined in the Loan  Agreement)  shall be
      borne and paid by  Assignor  on demand  by the  Lenders  and until so paid
      shall be added to the principal  amount of the  Obligations and shall bear
      interest  at the  Default  Rate  (as  such  term is  defined  in the  Loan
      Agreement).

            11.  Assignor  shall  have  the  duty,  through  counsel  reasonably
      acceptable  to  the  Lenders,   to  prosecute   diligently  any  trademark
      applications of the Trademarks pending as of the date of this Agreement or
      thereafter  until the  Obligations  shall have been paid in full,  to make
      federal  application on registrable but unregistered  Trademarks,  to file
      and prosecute  opposition and  cancellation  proceedings and to do any and
      all acts which are  necessary  or  desirable  to preserve and maintain all
      rights in the  Trademarks.  Any expenses  incurred in connection  with the
      Trademarks shall be borne by Assignor.  The Assignor shall not abandon any
      Trademark  without the consent of the Lenders,  which consent shall not be
      unreasonably withheld.

            12.   Assignor   shall  have  the  right  to  bring  any  opposition
      proceedings,  cancellation  proceedings  or  lawsuit  in its  own  name to
      enforce or protect the  Trademarks,  in which  event the  Lenders  may, if
      necessary, be joined as a nominal party to such suit if Lenders shall have
      been satisfied  that they are not incurring any risk of liability  because
      of such  joinder.  Assignor  shall  promptly,  upon demand,  reimburse and
      indemnify Lenders for all damages, costs and expenses,  including attorney
      fees,  incurred by Lenders in the  fulfillment  of the  provisions of this
      paragraph  12. The  obligations  of the Assignor  under this  paragraph 12
      shall survive the termination of this Agreement.

            13.  In the  event of the  occurrence  of a  Default  or an Event of
      Default under the Loan Agreement,  Assignor hereby authorizes and empowers
      the  Lenders to make,  constitute  and appoint any officer or agent of the
      Lenders as the Lenders may select,  in its sole discretion,  as Assignor's
      true and lawful  attorney-in-fact,  with the power to  endorse  Assignor's
      name on all applications,  documents, papers and instruments necessary for
      the Lenders to use the  Trademarks,  or to grant or issue any exclusive or
      nonexclusive license 



      under the  Trademarks  to anyone else, or necessary for Lenders to assign,
      pledge, convey or otherwise transfer title in or dispose of the Trademarks
      to anyone else.  Assignor  hereby  ratifies all that such  attorney  shall
      lawfully do or cause to be done by virtue  hereof.  This power of attorney
      shall be irrevocable for the life of this Agreement.

            14.  If  Assignor  fails  to  comply  with  any of  its  obligations
      hereunder,  the Lenders may do so in  Assignor's  name or in the  Lenders'
      name, but at Assignor's  expense,  and Assignor hereby agrees to reimburse
      the  Lenders in full for all  expenses,  including  reasonable  attorney's
      fees, incurred by the Lenders in protecting, defending and maintaining the
      Trademarks.

            15. No course of dealing between  Assignor and the Lenders,  nor any
      failure  to  exercise,  nor any  delay in  exercising,  on the part of the
      Lenders,  any  right,  power or  privilege  hereunder  or  under  the Loan
      Agreement  shall  operate  as a waiver  thereof;  nor shall any  single or
      partial exercise of any right, power or privilege  hereunder or thereunder
      preclude  any other or further  exercise  thereof or the  exercise  of any
      other right, power or privilege.

            16. All of the  Lenders'  rights and  remedies  with  respect to the
      Trademarks,  whether  established  hereby  or  by  the  Guaranty  or  Loan
      Agreement,  or by any other agreement(s) or by law shall be cumulative and
      may be exercised singly or concurrently.

            17. The  provisions  of this  Agreement  are  severable,  and if any
      clause or provision shall be held invalid and unenforceable in whole or in
      part in any jurisdiction,  then such invalidity or unenforceability  shall
      affect  only  such  clause  or  provision,   or  part  thereof,   in  such
      jurisdiction,  and shall not in any manner affect such clause or provision
      in any other  jurisdiction,  or any  other  clause  or  provision  of this
      Agreement in any jurisdiction.

            18.  This  Agreement  is subject to  modification  only by a writing
      signed by the parties, except as provided in paragraph 6.

            19. The  benefits and burdens of this  Agreement  shall inure to the
      benefit of and be binding upon the  respective  successors  and  permitted
      assigns of the parties.

            20. The validity and interpretation of this Agreement and the rights
      and  obligations of the parties shall be governed by the laws of the State
      of New Jersey.

            21. THE PARTIES HERETO AGREE TO THE  JURISDICTION OF THE FEDERAL AND
      STATE COURTS  LOCATED IN NEW JERSEY IN CONNECTION  WITH ANY MATTER ARISING
      HEREUNDER, INCLUDING THE COLLECTION AND ENFORCEMENT HEREOF.

            THE ASSIGNOR AND THE LENDERS EACH HEREBY IRREVOCABLY WAIVE ALL RIGHT
      TO TRIAL BY JURY IN ANY ACTION,  PROCEEDING OR COUNTERCLAIM ARISING OUT OF
      OR RELATING TO THIS  AGREEMENT OR ANY OTHER LOAN  DOCUMENTS OR THE ACTIONS
      OF THE LENDERS.  THIS WAIVER IS MADE KNOWINGLY AND IN CONSIDERATION OF THE
      ADVANCES MADE UNDER THE LOAN AGREEMENT.

            22. This Agreement,  the Guaranty, the Other Documents and the other
      Loan Documents embody the entire agreement and  understanding  between the
      Assignor  and  the  Lenders  and  supersedes  all  prior   agreements  and
      understandings relating to the subject matter hereof and thereof.
