                                  CORPORATION

                                    PREAMBLE

     American   Home   Products   Corporation   ("AHP")   and  the   undersigned
representatives of the purported class and subclasses defined herein (the "Class
Representatives") (together, the "Parties") hereby agree to propose a nationwide
Class  Action  Settlement  which would  resolve,  on the terms set forth in this
Settlement Agreement,  "Settled Claims" against AHP and other "Released Parties"
arising  from  the  marketing,  sale,  distribution  and use of the  diet  drugs
Pondimin(R)and  Redux(TM),  pending in various courts, including but not limited
to claims  which have been made in the actions  that have been  transferred  for
coordinated or consolidated  pretrial  proceedings to the United States District
Court for the Eastern  District of  Pennsylvania  under Docket No. MDL 1203 (the
"Federal  District Court"),  in Vadino et al. v. AHP (Docket No.  MID-L-425-98),
and in the numerous other State Courts around the United States.  The Parties to
this Agreement are aware of the following  certified or conditionally  certified
nationwide or statewide classes involving Pondimin(R)and  Redux(TM)as of October

Diet  Drug  Products  Liability   Litigation,   MDL  1203)  (nationwide  medical
monitoring  class);  West  Virginia  (Burch  et al.  v. AHP,  Civil  Action  No.
97-C-204(1-11))  (statewide  personal  injury  and  medical  monitoring  class);
Illinois  (Rhyne  v.  AHP,  98  CH  4099)   (statewide   refund  and  monitoring

97-2-06368-4) (statewide medical monitoring class).

     This  Settlement  Agreement  shall not be construed as evidence of or as an
admission by AHP of any liability or wrongdoing whatsoever or as an admission by
the Class  Representatives  or members of the Settlement Class as defined herein
("Class Members") of any lack of merit in their claims.

         Accordingly, AHP and the Class Representatives hereby agree, subject to
Final Judicial  Approval  (except as to the  Accelerated  Implementation  Option
("AIO")  described  in  Section  V  below),  compliance  with  applicable  legal
requirements, and other conditions, all as set forth below, that Fund A and Fund
B shall be established, from which the benefits described herein will be paid to
the Class Members of the proposed Settlement Class and Subclasses,  and that the
Settled Claims against AHP and other Released Parties,  as defined herein,  will
be settled, compromised and released, in accordance with the following terms.

I.       DEFINITIONS

         For  purposes  of  this   Settlement   Agreement  the  following  terms
(designated by initial capitalization  throughout this Agreement) shall have the
meanings set forth in this Section.  Terms used in the singular  shall be deemed
to include the plural and vice versa.

     1.   "Adjusted  Maximum  Available  Fund B Amount"  shall  mean the  amount
          determined  by adding the balance in Fund A which was  transferred  to
          Fund B pursuant  to the terms of Section  III.A.4.  of the  Settlement
          Agreement  to the Maximum  Available  Fund B Amount as defined in this
          section. If there has been no such transfer, then the Adjusted Maximum
          Available Fund B Amount shall be equal to the Maximum Available Fund B
          Amount.  The "Maximum  Available  Fund B Amount" shall mean the amount
          determined by adding $2,550,000,000 and the Fund B Accretions,  and by
          then  subtracting  from the  resulting  sum:  (i) the  Fund B  Initial
          Payment under Section III.C.2; (ii) all amounts paid or transferred to
          the  Trustees  to pay Fund B  benefits  pursuant  to Fund B  Quarterly
          Notices under Section  III.C.3 and pursuant to Requests for Fund B AIO
          Payments under Section V.F; and (iii) Credits to which AHP is entitled
          under  Section   VII.A   (Opt-Out   Credits)  and  Section   VII.C.1.g
          (Cross-Claim  Credits),  provided  that Initial  Opt-Out  Credits,  as
          defined in Section  VII.A.2,  shall be applied to reduce the  Adjusted
          Maximum  Available  Fund B Amount only when and as provided in Section
          VII.A.  "Fund B Accretions" are determined as follows:  Beginning with
          the earlier of the Final  Judicial  Approval Date or the date on which
          it is determined  that Final  Judicial  Approval will not be obtained,
          the  Trustees  shall  calculate a quarterly  accretion  to the Maximum
          Available  Fund B Amount  which  will be one and  one-half  percent (1
          1/2%) of the  Maximum  Available  Fund B Amount  determined  as of the
          close of each AIO  Fiscal  Quarter  or Fiscal  Quarter,  whichever  is
          applicable.  Such accretions  shall be added to the Maximum  Available
          Fund B Amount as of the first day of the quarter following the quarter
          for which such accretion is calculated.

          Year shall be the partial calendar year beginning on the date on which

                    CH 4099);  and Texas  (Earthman v. AHP, No.  97-10-03970 CV,
                    Dist.  Ct.  Montgomery  Co.  Texas).  The  payment  of  said
                    compensation, relating to Fund A, to Plaintiffs' Counsel and
                    the certified State and Federal Court Class  Representatives
                    shall be in such  manner  and in such  amounts as the Court,
                    with advice and counsel of the State Court Judicial Advisory
                    Committee, may determine is appropriate,  as contemplated by
                    Sections  VIII.B.3 and  VIII.E.1.a  hereof and pursuant to a
                    Fund A Escrow Account  Agreement  substantially  in the form
                    attached  hereto as Exhibit  "2." AHP shall take no position
                    on the amount of such fees to be awarded as attorneys'  fees
                    or incentive  awards or the  allocation  thereof.  All Class
                    Members  shall have  standing  to object to or  support  the
                    award of  attorneys'  fees and  incentive  awards  for Class
                    Representatives  from the Fund A Escrow Account.  Any amount
                    in the Fund A Escrow Account not awarded in attorneys'  fees
                    shall be returned to AHP by order of the Court.

               4.   When the Trustees  decide that Fund A's  purposes  have been
                    met,  the  remaining  balance,  if any,  in Fund A shall  be
                    transferred to Fund B.

               5.   Any  transfer  from  Fund A to Fund B will  not  reduce  the
                    maximum obligation of AHP to make payments to Fund B.

         C.    FUND B

               1.   Fund B  Amounts.  Fund B shall  consist  of (i)  the  Fund B
                    Initial  Payment  under  Section  III.C.2;  (ii)  all Fund B
                    Deposit  Amounts paid  pursuant to Fund B Quarterly  Notices
                    under Section III.C.3;  (iii) all Fund B AIO Deposit Amounts
                    paid  pursuant to  Requests  for Fund B AIO  Payments  under
                    Section V.F;  and (iv) all interest and other income  earned
                    by the Trust on such amounts.

               2.   Fund B Initial  Payment.  No later than five  Business  Days
                    after  the  Preliminary  Approval  Date,  AHP  shall pay $25
                    million into Fund B.

               3.   Additional Fund B Deposits.  Beginning on the Final Judicial
                    Approval  Date,  the  Trustees  may  request in writing on a
                    quarterly  basis  (each  a  "Fund B  Quarterly  Notice")  an
                    additional  amount (such amount being referred to as a "Fund
                    B Deposit Amount"):

                    a.   to pay claims  received  which qualify for payment from
                         Fund B  pursuant  to Section  IV.B.,  awards of counsel
                         fees  and  costs   under   Section   VIII.E.1.b.,   and
                         authorized  administrative expenses which have not been
                         paid due to an  insufficient  cash  balance  in Fund B,
                         and/or

                    b.   to  maintain  a  $50  million  reserve  in  Fund  B for
                         administrative expenses (the "Administrative Reserve").

                           AHP shall pay each Fund B Deposit Amount so requested
                           no later  than 15 days  after  the date on which  AHP
                           receives from the Trustees a Fund B Quarterly  Notice
                           requesting  such  Fund B  Deposit  Amount;  provided,
                           however,  that AHP's obligation to pay Fund B Deposit
                           Amounts shall at all times be limited to the Adjusted
                           Maximum Available Fund B Amount.

               4.   Termination of AHP's Fund B Payment Obligations.

                    a.   AHP's  obligation  to  make  payments  to  Fund B shall
                         terminate  upon the  earlier  of: (i) the date of AHP's
                         payment  into Fund B of the  amount  that  reduces  the
                         Adjusted  Maximum  Available  Fund B Amount to zero; or
                         (ii) the date of AHP's  payment  to Fund B of the Final
                         Projected Amount under Section  III.C.4.b.  below. Such
                         payment  shall be referred to in this  Agreement as the
                         "Final Payment."

                    b.   The  Final  Projected  Amount  shall be  determined  as
                         follows:

                    (i)  As of  the  end  of  the  sixteenth  Fiscal  Year,  the
                         Trustees shall cause an actuarial  determination  to be
                         made, based on the experience of the Settlement  Trust,
                         as to the amount of  additional  funds,  if any,  which
                         will be required to fund  payments to Class Members who
                         have  qualified  or who are  likely to  qualify  in the
                         future for benefits from Fund B in accordance  with the
                         provisions of Section IV.B and Section IV.C, determined
                         without  regard to any  limitation on the obligation of
                         AHP to make Fund B payments under this  Agreement,  and
                         to  fund  the  payment  of  associated   administrative
                         expenses.   The   Trustees   shall   also   take   into
                         consideration   the  then  cash   balance   in  Fund  B
                         (including the Administrative  Reserve),  its projected
                         future investment and other income,  and an estimate of
                         required future administrative expenses.

                    (ii) No later  than 30 days  after  the  date on  which  the
                         Trustees  are  required  to  make  the  estimate  under
                         Section  III.C.4.a.(i),  the Trustees  shall  provide a
                         written report  ("Final  Projected  Amount  Report") to
                         Class  Counsel and to AHP setting  forth the  Trustees'
                         projection of the amount of additional  funds,  if any,
                         which will be necessary to meet the obligations of Fund
                         B as  described  in  Section  III.C.4.a.(i).  The Final
                         Projected  Amount Report shall  contain all  supporting
                         information necessary to allow Class Counsel and AHP to
                         evaluate  the  accuracy  and   reasonableness   of  the
                         estimate.  Such supporting  information  shall include,
                         without  limitation,   the  Trustees'  methodology  for
                         making the estimate and any assumptions  used in making
                         the  estimate.  AHP and/or Class Counsel shall have the
                         right  to  obtain  from  the  Trustees  any  additional
                         information  reasonably  requested by them  relating to
                         the estimate  contained in the Final  Projected  Amount
                         Report.

                    (iii)Within 30 days  after  the date of the Final  Projected
                         Amount Report,  Class Counsel and/or AHP may appeal the
                         Trustees' estimate to the Court, which shall modify the
                         Trustees'  estimate  to the extent  appropriate  upon a
                         judicial finding that the Trustees' estimate was either
                         unreasonable or lacking in substantial support. If such
                         an  appeal  is not  taken or if such an appeal is taken
                         and the Court  determines  not to modify the  Trustees'
                         estimate,  then the Trustees' estimate, as set forth in
                         the Final  Projected  Amount  Report,  will  become the
                         "Final   Projected   Amount"   for   purposes  of  this
                         Agreement.  If such an appeal of the Trustees' estimate
                         is taken and the Court modifies the estimated amount in
                         connection  with  such an  appeal,  then the  estimated
                         amount  determined  by the Court will become the "Final
                         Projected  Amount" for purposes of this Agreement.  The
                         Parties waive any right to appeal any  determination of
                         the Court with respect to the Final Projected Amount.

                    (iv) If the Adjusted  Maximum  Available Fund B Amount as of
                         the  date  on  which  the  Final  Projected  Amount  is
                         determined  exceeds the Final  Projected  Amount,  then
                         within  five  business  days  after  the  date  of  the
                         determination   of  the  Final   Projected   Amount  in
                         accordance with this Agreement, AHP shall pay the Final
                         Projected  Amount  into Fund B and such  payment  shall
                         constitute the Final Payment under this  Agreement.  If
                         the Final Projected Amount exceeds the Adjusted Maximum
                         Available  Fund B Amount  as of the  date on which  the
                         Final Projected Amount is determined,  then within five
                         business  days after the date of the  determination  of
                         the  Final  Projected  Amount in  accordance  with this
                         Agreement, AHP shall pay the Adjusted Maximum Available
                         Fund B  Amount  into  Fund  B and  such  payment  shall
                         constitute the Final Payment under this  Agreement.  In
                         no event  shall  AHP's  payment  into Fund B exceed the
                         Adjusted Maximum Available Fund B Amount.

                    c.   The monies held by Fund B shall be available  and shall
                         be used to pay all  benefits  payable  from Fund B, all
                         attorneys'  fees and  common  benefit  fees  and  costs
                         awarded  by the  Court  in  relation  to Fund B and all
                         proper  administrative  expenses  associated  with  the
                         administration  of the  Settlement  and the  Settlement
                         Trust  insofar  as they  relate  to Fund B, and for the
                         purposes described in Section III.C.4.d.

                    d.   The Trustees shall use any residual funds  remaining in
                         Fund B after the satisfaction of all Fund B obligations
                         to Class  Members to either pay for or create a reserve
                         for payment of all  administrative  expenses which have
                         been or will be incurred to wind up the  administration
                         of  the  Trust  on  behalf  of  the  Settlement  Class,
                         including   adequate   provision  for   maintaining  or
                         disposing of the database  created  pursuant to Section
                         VI.C.3.c,  and shall transfer any funds remaining after
                         satisfaction  of the foregoing to the Medical  Research
                         and Education Fund created under Section IV.A.3.a.

         D.   OTHER PROVISIONS

               1.   The  Settlement  Trust  shall be  structured  and managed to
                    qualify as a Qualified Settlement Fund under Section 468B of
                    the Internal  Revenue Code and related  regulations and will
                    contain  customary  provisions  for  such  trusts  including
                    obligations of the Settlement  Trust to make tax filings and
                    to  provide  to AHP  information  to  permit  AHP to  report
                    deductions properly for tax purposes.

               2.   The  Parties  agree  that  all of  the  amounts  being  paid
                    pursuant to the terms of this  Settlement  are being paid as
                    damages (other than punitive  damages) on account of alleged
                    physical  personal  injuries or alleged physical sickness of
                    the members of the Settlement  Class as described in Section
                    104(a)(2) of the Internal  Revenue Code of 1986,  as amended
                    (the "Code").  The Parties further agree that the claims set
                    forth in the  definition  of Settled  Claims in Section I.53
                    have their origin in such alleged physical personal injuries
                    or physical sickness.

               3.   Except  as  provided  in  Section V herein  relating  to the
                    Accelerated   Implementation   Option,  AHP  shall  have  no
                    financial  obligations under this Settlement Agreement other
                    than as  explicitly  set forth in this  Section  III  (AHP's
                    Payment  Obligations).  AHP shall have no responsibility for
                    the management of the  Settlement  Trust or any liability to
                    any Class Member  arising from the handling of claims by the
                    Trustees.

         E.    SECURITY ARRANGEMENTS

               1.   During  the  period  beginning  on the  first  Business  Day
                    following  the Trial Court  Approval  Date and ending on the
                    fifth  Business Day  following the Final  Judicial  Approval
                    Date, AHP shall maintain  credit  facilities in an aggregate
                    principal  amount of One  Billion  Dollars  ($1,000,000,000)
                    exclusively  as  security  for its  obligations  under  this
                    Settlement  Agreement over the sum of (1) the greater of (a)
                    the aggregate  minimum principal amount of credit facilities
                    that  would be  required  by  Moody's  Investors  Service to
                    satisfy  back-up   liquidity  on  AHP's   commercial   paper
                    obligations or (b) the aggregate minimum principal amount of
                    credit  facilities  that  would be  required  by  Standard &
                    Poor's  Rating  Services as  sufficient  to satisfy  back-up
                    liquidity on AHP's  commercial paper  obligations,  plus (2)
                    the amount of any uses (other than the  payments  under this
                    Settlement  Agreement) for which such credit facilities have
                    been  committed,  plus (3)  outstanding  drawings under such
                    credit facilities.

               2.   Fifteen days after the Final Judicial  Approval Date, or the
                    first Business Day thereafter if such fifteenth day is not a
                    Business Day, AHP shall establish and thereafter  maintain a
                    fund (the "Security Fund") consisting of cash and high-grade
                    marketable commercial securities (which shall consist of the
                    "Permitted  Investments,"  defined  herein)  selected by AHP
                    having  a  principal  value  equal to $370  million.  If the
                    credit rating for AHP as reported by both Moody's  Investors
                    Service  and  Standard  & Poor's  Rating  Services  is below
                    investment  grade at any time during which the Security Fund
                    must be maintained  hereunder,  AHP shall deposit additional
                    cash and  Permitted  Investments  selected  by AHP having an
                    aggregate principal value of an additional $180 million. For
                    purposes  of  this  Section  III.E,   the  term   "Permitted
                    Investments"  shall mean any of the  following:  (a) readily
                    marketable  direct  obligations  of the United States or any
                    agency   or    instrumentality    thereof   or   obligations
                    unconditionally  guaranteed  by the full faith and credit of

                    the  case  of  all  such   obligations   other  than  direct

                    of  deposit  or time  deposits  maturing  within 365 days of
                    purchase  with any  commercial  bank  that (1) has  deposits
                    insured by the Federal Deposit Insurance Corporation, (2) is
                    organized  under the laws of the United  States or any state
                    thereof, (3) has a minimum long-term rating of "A-3" (or the
                    then  equivalent)  by  Moody's   Investors   Service  and  a
                    long-term  rating  of  "A-"  (or  the  then  equivalent)  by
                    Standard  & Poor's  Rating  Services,  and (4) has  combined

                    more than 180 days from the date of acquisition  thereof; or
                    (d) investments,  classified as current assets of AHP or any
                    of its  subsidiaries  under  generally  accepted  accounting
                    principles,  in money market investment  programs registered
                    under the Investment Company Act of 1940, as amended,  which
                    are  administered  by financial  institutions  that have the
                    highest  rating  obtainable  from either  Moody's  Investors
                    Service  or  Standard  &  Poor's  Rating  Services,  and the
                    portfolios of which are limited solely to investments of the
                    character,  quality and  maturity  described in clauses (a),
                    (b) or (c) of this definition.

               3.   The Security Fund shall be terminated  upon AHP's making the
                    Final Payment provided for in Section III.C.4.a.

               4.   AHP shall be entitled to withdraw from the Security Fund all
                    income earned  thereby.  However,  in the event that, and so
                    long as, the credit  rating of AHP  reported by both Moody's
                    Investors  Service and Standard & Poor's Rating  Services is
                    below investment grade at any time during which the Security
                    Fund must be maintained,  AHP shall no longer be entitled to
                    withdraw from the Security  Fund the income earned  thereby,
                    except that AHP shall thereafter be entitled to withdraw, at
                    each tax payment  date,  such amount  thereof as shall equal
                    all  federal,  state and  local  taxes  payable  by AHP with
                    respect to or on account of the whole amount of the Security
                    Fund.  AHP  shall  be  responsible  for the  payment  of all
                    federal, state and local taxes payable with respect to or on
                    account of the Security Fund.

               5.   AHP  shall  grant  to  the  Trustees  a  perfected  security
                    interest  in the  Security  Fund  as  collateral  for  AHP's
                    obligations under the Settlement  Agreement  pursuant to the
                    terms of a Security  Fund and Escrow  Agreement  in the form
                    appended  hereto as Exhibit  "3"  hereto.  The assets in the
                    Security Fund shall at all times be owned by AHP, subject to
                    the rights of the Trust as a secured creditor.

               6.   For  purposes  of this  Settlement  Agreement,  an  "Uncured
                    Failure to Make Payment" is an event in which:

                    a.   AHP fails to make a payment to Fund B which was due and
                         not timely  paid,  and such failure to make payment was
                         due  to  either  a  financial  inability  to  pay  or a
                         deliberate  unwillingness  to pay, such  determinations
                         having  been  made  by  order  of the  Court  after  an
                         evidentiary hearing (a "Nonpayment Hearing"); and

                    b.   AHP fails to make that payment within thirty days after
                         such  order  becomes  final  after  exhaustion  of  all
                         appeals,  if any,  or AHP  fails to make  that  payment
                         thirty  days after a Trial  Court  order  declaring  an
                         Uncured Failure to Make Payment and is unable to obtain
                         a stay of that order pending an appeal from such order.

               7.   At least thirty days prior to any  Nonpayment  Hearing,  AHP
                    and Class  Counsel  shall have the right to receive from the
                    Trustees  such   information  as  they  reasonably   request
                    relating to the  Trustees'  claim that such  payment was due
                    and owing,  as to which  issue the  Trustees  shall have the
                    burden of proof.

               8.   In  the  event  of  an  Uncured  Failure  to  Make  Payment,
                    securities  and/or  cash  in  the  Security  Fund  having  a
                    principal  value equal to the entire  amount of the Security
                    Fund shall be  transferred  to the escrow agent of an escrow
                    account to be maintained  under the supervision of the Court
                    (the "Security Fund Escrow Account"),  without impairing the
                    security  interest of the Trust. The portion of the Security
                    Fund  Escrow   Account,   if  any,  needed  to  satisfy  the
                    obligations of AHP under the Settlement  Agreement  shall be
                    paid to the  Trust  pursuant  to  order  of the  Court or on
                    agreement of the Parties.  Any unused amount of the Security
                    Fund Escrow Account shall be returned to AHP at the time the
                    Final  Payment  is made or  deemed to have  been  made.  Any
                    income  earned on the account  shall  remain the property of
                    the account, and all federal,  state and local taxes payable
                    with respect to the Security  Fund Escrow  Account  shall be
                    paid  out  of  the  account.   Additional   conditions   and
                    procedures for the establishment, operation and distribution
                    of the Security Fund Escrow Account are set forth in Exhibit
                    "3," which is to be executed  substantially  in that form by
                    the escrow agent.

               9.   In the event of the following occurrences:

                    a.   The occurrence of more than one Uncured Failure to Make
                         Payment within a two-year period; and

                    b.   The  depletion of the amount of the assets which AHP is
                         required to have on deposit in the Security  Fund or in
                         the Security  Fund Escrow  Account  described  above by
                         more than fifty percent of the then-required  amount of
                         assets; and

                    c.   A  determination  by  the  Court  after  notice  and an
                         opportunity to be heard by all interested  parties that
                         the  remaining  assets in the  Security  Fund or in the
                         Security  Fund  Escrow  Account  are not  likely  to be
                         sufficient to pay the remaining  Fund B obligations  to
                         Class Members as of that point in time;

                           all Diet Drug  Recipients  who (i) are diagnosed by a
                           Qualified Physician as FDA Positive or as having Mild
                           Mitral  Regurgitation by an Echocardiogram  performed
                           between the commencement of Diet Drug use and the end
                           of the Screening  Period and who have  registered for
                           settlement  benefits by Date 2, or (ii) are diagnosed
                           as having Endocardial Fibrosis by September 30, 2005,
                           and have  registered  for Fund B benefits  by January
                           31,   2006,    together    with   their    associated
                           Representative and/or Derivative Claimants, will have
                           a right to opt out of the  Settlement  and pursue all
                           of their Settled  Claims (except for those claims set
                           forth in subparagraphs (e) and (g) of Section I.53 of
                           this  Agreement),  against AHP and the other Released
                           Parties,  including  claims for punitive and multiple
                           damages   (hereinafter   the  "Financial   Insecurity
                           Opt-Out Right"), provided such Class Members have not
                           received Matrix-Level V benefits set forth in Section
                           IV.B.2.

               10.  Within  thirty  (30)  days of the  date of the  entry of any
                    Order  determining that the remaining assets in the Security
                    Fund or in the Security  Fund Escrow  Account are not likely
                    to be sufficient to pay the remaining Fund B obligations, as
                    referred to in Sections III.E.6.a and III.E.9.c,  above, the
                    Trustees  and/or  Claims   Administrator(s)   shall  provide
                    written   notice  to  all  affected  Class  Members  of  the
                    circumstances   giving  rise  to  the  Financial  Insecurity
                    Opt-Out Right by first class mail,  postage prepaid.  Within
                    one-hundred  and twenty  (120) days of the  transmission  of
                    that notice, each Class Member who is eligible to exercise a
                    Financial Insecurity Opt-Out Right may send a written notice
                    advising the Trustees and/or Claims  Administrator(s) of the
                    Class Member's election to exercise the Financial Insecurity
                    Opt-Out Right on a form  prescribed  by the Trustees  and/or
                    Claims  Administrator(s).  In the event of such an  opt-out,
                    the Class  Member may pursue any and all claims  (except for
                    those  claims  set  forth  in  subparagraphs  (e) and (g) of
                    Section  I.53 of this  Agreement)  against  AHP in the legal
                    system,  and none of the  Released  Parties  may  assert any
                    defense to such claims  based on any statute of  limitations
                    or  repose,  the  doctrine  of  laches,  any  other  defense
                    predicated  on the failure to timely  pursue the claim,  any
                    defense based on "splitting" a cause of action,  any defense
                    based  on any  release  signed  pursuant  to the  Settlement
                    Agreement,  and/or any other  defense based on the existence
                    of the Settlement  Agreement,  except to the extent provided
                    in Section  III.E.9 of this  Agreement.  In any legal action
                    commenced  by a Class  Member  exercising a right of opt-out
                    under these circumstances, the Class Member shall reduce the
                    amount of his or her recovery by the amount of any cash that
                    the Class  Member  has  received  from AHP  and/or the Trust
                    under  any  terms  of  the  Settlement.  There  shall  be no
                    deduction, offset, or reduction for any Medical Screening or
                    Medical Services received by a Class Member.

               11.  Nothing  contained in this Section of the Agreement shall be
                    construed to be a waiver of or a limitation  on rights which
                    the Class Members,  Class  Representatives or Trustees would
                    otherwise have under the law in the event of a breach of the
                    Settlement Agreement.

               12.  Immediately  upon  termination  of the  Security  Fund under
                    Section III.E.3 above, any remaining balance in the Security
                    Fund, including any income earned thereon, shall be released
                    to AHP.

                    Fund A  possesses  sufficient  assets  to pay such  benefits
                    after  paying or creating a reserve for payment of all other

               reimbursement  benefits  will be  made  available  to  Diet  Drug
               Recipients or their Representative  claimants only if, and to the
               extent  that,  Fund A  possesses  sufficient  assets  to pay such

               Matrix B-1.

          f.   If a Diet Drug  Recipient  qualifies  for Matrix  payments due to
               more than one condition,  the Diet Drug  Recipient  and/or his or
               her associated  Representative and Derivative  Claimants who have
               registered (or who are deemed to have  registered) for settlement
               benefits by Date 2 shall be  entitled to receive  only the higher
               of such payments, but not both such payments.

          g.   Matrices  A-1 and B-1 set forth the maximum  aggregate  amount to
               which  the  Diet  Drug  Recipient  or his  or her  Representative
               Claimants are collectively entitled to receive from Fund B. Where
               there is more than one  Representative  Claimant  associated with
               any  particular  Diet Drug  Recipient  eligible  for such  Matrix
               Compensation     Benefits,    the    Trustees    and/or    Claims
               Administrator(s)  shall  allocate  this  amount  among all of the
               Representative  Claimants who have made a claim for such benefits
               according to applicable  law.  Matrices A-2 and B-2 set forth the
               maximum  aggregate  amount  to  which  all  Derivative  Claimants
               associated   with  any   particular   Diet  Drug   Recipient  are
               collectively entitled to receive from Fund B. Where there is more
               than one Derivative  Claimant associated with any particular Diet
               Drug Recipient  eligible for such Matrix  Compensation  Benefits,
               the Trustees  and/or Claims  Administrator(s)  shall allocate the
               Matrix amount, pro rata among all of the Derivative Claimants who
               have  made  a  claim  for  such  benefits,  to  the  extent  that
               applicable  state law recognizes  that they have a claim for loss
               of consortium, services or support.

               regurgitation)  and as having  Mild  Mitral  Regurgitation  by an
               Echocardiogram  performed  between the  commencement of Diet Drug
               use and the end of the Screening  Period and who have  registered
               for  settlement   benefits  by  Date  2,  and  their   associated
               Representative  and Derivative  Claimants who have registered (or
               who are deemed to have  registered)  for  settlement  benefits by
               Date 2, shall be eligible for Matrix  payments  based upon either
               the aortic or the mitral valve.

          k.   Diet Drug  Recipients  who have  been  diagnosed  by a  Qualified
               Physician as having  Endocardial  Fibrosis by September 30, 2005,
               and  have  registered  for  Matrix   Compensation   Benefits  for
               Endocardial  Fibrosis by January 31, 2006,  and their  associated
               Representative  and Derivative  Claimants who have registered (or
               who are deemed to have registered) for these settlement  benefits
               by  January  31,  2006,  shall  be  entitled  to the  Endocardial
               Fibrosis   benefits  as  set  forth  in  Sections   IV.B.2.a  and
               IV.B.2.c.(5)(a),  regardless  of  whether  or not the  Diet  Drug
               Recipient had valvular regurgitation.

               l.   A  Representative  Claimant is deemed to have registered for
                    settlement benefits either when the Representative  Claimant
                    registers  for  benefits or, if  applicable,  as of the date
                    when the Diet Drug  Recipient to which the claim relates has
                    registered for settlement benefits.

         C.       PAYMENT PROVISIONS

                    1.   The  Matrix  payment   amounts  set  forth  in  Section
                         IV.B.2.a  above will be  increased  by two percent (2%)
                         per year, compounded annually, beginning one year after
                         the Final Judicial Approval Date. In the event that the
                         Settlement does not receive Final Judicial  Approval or
                         is terminated  by AHP in accordance  with its terms for
                         any  other  reason,  then  for  purposes  of  providing
                         benefits to each Class  Member who has entered  into an
                         Individual   Agreement   pursuant  to  the  Accelerated
                         Implementation  Option  (described in Section V below),
                         the Matrix payment amounts shall be increased by 2% per
                         year, compounded annually, beginning in the second "AIO
                         Fiscal   Year"  (as  defined  in  Section  I.6  and  as
                         discussed in Section V.H.3 hereof).

                    2.   A "Matrix  Payment  Cut-Off  Date" is  established  for
                         purposes of this Settlement. The Matrix Payment Cut-Off
                         Date  shall be a date  which is 14 years from the Final
                         Judicial Approval Date or December 31, 2015,  whichever
                         is earlier. Those Class Members who fail to qualify for
                         payment on the Matrices by the Matrix  Payment  Cut-Off
                         Date  shall  have no  further  right to claim  benefits
                         under  Fund B or to  exercise a  Back-End  Opt-Out  (as
                         described in Section  IV.D.4 below).  However,  where a
                         Diet Drug  Recipient  does  qualify  for payment on the
                         Matrices by the Matrix  Payment  Cut-Off Date, the Diet
                         Drug Recipient and/or the associated Representative and
                         Derivative  Claimants  may  continue to receive  higher
                         amounts of Matrix Compensation Benefits, if any, if the
                         condition of the Diet Drug  Recipient  which  qualified
                         such  person  for  such  payment  progresses  to a more
                         severe condition after the Matrix Payment Cut-Off Date.

                    3.   Once a Diet Drug  Recipient has reached a  Matrix-Level
                         Condition  before the Matrix Payment  Cut-Off Date, the
                         Diet Drug Recipient and any  associated  Representative
                         and/or  Derivative  Claimants  can  step  up to  higher
                         Matrix-Level   Conditions   and   will  be   paid   the
                         incremental  dollar amount, if any, by which the Matrix
                         payment for the higher  Matrix-Level  Condition exceeds
                         the Matrix payment previously received. Notwithstanding
                         the  foregoing,  Class  Members who seek  benefits  for
                         Endocardial  Fibrosis  must  qualify for payment on the
                         Matrices for that  condition by September  30, 2005 and
                         register (or be deemed to have  registered)  for Matrix
                         Compensation   Benefits  for  Endocardial  Fibrosis  by
                         January 31, 2006.

                  4.       Prior to the  payment of Fund B benefits to any Class
                           Member,  the Trustees and/or Claims  Administrator(s)
                           shall  deduct  the  amount  provided  for in  Section
                           VIII.E.1.b for the payment of attorneys' fees.

          D.   OPT-OUT RIGHTS

               1.   DERIVATIVE  CLAIMANTS.  As to all  opt-outs,  where there is
                    both a Diet Drug Recipient or a Representative  Claimant and
                    one or more Derivative Claimants,  the Diet Drug Recipient's
                    or the  Representative  Claimant's  exercise  or  failure to
                    exercise an opt-out right shall be binding on the associated
                    Derivative Claimant(s).

               2.   INITIAL OPT-OUT

                    a.   ELIGIBILITY: All Class Members are eligible to exercise
                         an Initial Opt-Out right.

                    b.   METHOD OF EXERCISE:  Each Class  Member  wishing to opt
                         out from this  Settlement  must sign and submit  timely
                         written notice to the Claims  Administrator(s),  with a
                         copy to AHP,  clearly  manifesting  the Class  Member's
                         intent  to  opt  out  of  the  Settlement.  The  Claims
                         Administrator(s) shall then submit all Opt-Out forms to
                         the Court. The Court shall be the official  registry of
                         Opt-Outs.  This  written  notice  shall  be in the form
                         appended  hereto as Exhibit  "6" or in a  substantially
                         identical  written   manifestation  of  intent.  To  be
                         effective,  this  written  notice  must be  signed  and
                         submitted  by the  expiration  of the  Initial  Opt-Out
                         Period.  The  Parties  will  recommend  that the  Court
                         approve an Initial  Opt-Out Period of 120 days from the
                         date on which class notice commences.

                    c.   EFFECT OF  EXERCISE:  Any Class  Member  who timely and
                         properly   exercises  an  Initial   Opt-Out  right  may
                         initiate,  continue  with,  or otherwise  prosecute any
                         legal  claim  against  AHP  and  the  Released  Parties
                         without any  limitation,  impediment or defense arising
                         from the terms of the Settlement  Agreement and subject
                         to all  defenses  and rights which AHP and the Released
                         Parties  would  otherwise  have in the  absence  of the
                         Settlement  Agreement.  AHP agrees that it will not use
                         the Settlement  Agreement or any proceedings  connected
                         therewith to cause delay to any Class Member who timely
                         and properly  exercises  his/her  Initial Opt-Out right
                         and initiates,  continues with, or otherwise prosecutes
                         a  claim  against  AHP.  Lawsuits  initiated  by  Class
                         Members  who timely and  properly  exercise  an Initial
                         Opt-Out  shall be subject to the  provisions of Section
                         VIII.F.3.

                    d.   REVOCATION OF EXERCISE:  Any Class Member may revoke an
                         election  to  exercise a right of Initial  Opt-Out  and
                         thereby   receive  the  benefits  of  the   Settlement,
                         provided  that  the  revocation  takes  place  with the
                         written consent of AHP, which shall not be unreasonably
                         withheld.

          3.   INTERMEDIATE OPT-OUT

               a.   ELIGIBILITY:  All Diet Drug Recipients (other than those who
                    have entered into AIO Individual  Agreements pursuant to the
                    Accelerated  Implementation  Option)  who are not members of
                    Subclasses 2(a), 2(b) or 3, and who have been diagnosed by a
                    Qualified  Physician  as FDA  Positive by an  Echocardiogram
                    performed  between the commencement of Diet Drug use and the
                    end  of  the   Screening   Period,   and  their   associated
                    Representative and/or Derivative Claimants,  are eligible to
                    exercise a right to Intermediate Opt-Out

               b.   METHOD OF EXERCISE:  Each Class Member who wants to exercise
                    a right of  Intermediate  Opt-Out must do so by  completing,
                    signing, and timely submitting a written notice of the Class
                    Member's  intent  to do so in the form  appended  hereto  as
                    Exhibit  "7." This  written  notice must be submitted to the
                    Court, the Trustees and/or Claims  Administrator(s),  and to
                    AHP,  no later than Date 2. In that form,  the Class  Member
                    must clearly  express  his/her desire to exercise a right of
                    Intermediate Opt-Out,  certify that he/she is eligible to do
                    so,  and  expressly  acknowledge  an  understanding  of  the
                    Settlement  rights and benefits that will be relinquished by
                    the  exercise of the  Intermediate  Opt-Out  right.  A Class
                    Member may not exercise an Intermediate  Opt-Out right after
                    receiving either $6,000 in cash or any portion of $10,000 in
                    medical  services  in the case of members of  Subclass  1(b)
                    (pursuant to Section IV.A.1.c  above),  or $3,000 in cash or
                    any  portion  of $5,000 in medical  services  in the case of
                    members of  Subclass  1(a)  (pursuant  to  Section  IV.A.2.c
                    above).  If a member of Subclass  1(a) or 1(b) is  diagnosed
                    with a Matrix-Level Condition and exercises an opt-out right
                    after the end of the  Initial  Opt-Out  Period,  the opt-out
                    shall be deemed a Back-End Opt-Out.

               c.   EFFECT OF EXERCISE:  The Intermediate  Opt-Out is subject to
                    the  following  provisions.  A Class  Member  who timely and
                    properly exercises an Intermediate  Opt-Out right may pursue
                    all of his or her Settled  Claims  (except for those  claims
                    set forth in  subparagraphs  (e) and (g) of  Section  I.53),
                    against the AHP Released Parties and/or the Non-AHP Released
                    Parties,  but may only assert a claim  against AHP  Released
                    Parties  and/or the Non-AHP  Released  Parties  based on the
                    heart valve of the relevant  Diet Drug  Recipient  which was
                    diagnosed  by a Qualified  Physician  as FDA  Positive by an
                    Echocardiogram  performed  between the  commencement of Diet
                    Drug use and the end of the  Screening  Program.  If, at any
                    time after a Class Member exercises an Intermediate  Opt-Out
                    right,  the Class  Member  initiates  a lawsuit  seeking  to
                    pursue a Settled  Claim  against  AHP or any other  Released
                    Party, the Released Party shall have the right to challenge,
                    in such  lawsuit  only,  whether  the opt-out was timely and
                    proper,  including  whether the Class Member was eligible to
                    exercise such an opt-out  right.  With respect to each Class
                    Member who timely and properly  exercises  the  Intermediate
                    Opt-Out right and who initiates a lawsuit against any of the
                    Released  Parties within one year from the date on which the
                    Intermediate  Opt-Out right is  exercised,  the AHP Released
                    Parties shall not assert any defense based on any statute of
                    limitations  or repose,  the  doctrine of laches,  any other
                    defense  predicated  on the  failure  to timely  pursue  the
                    claim,  any defense based on  "splitting" a cause of action,
                    any  defense  based on any  release  signed  pursuant to the
                    Settlement Agreement,  and/or any other defense based on the
                    existence of the Settlement Agreement,  except to the extent
                    provided   herein.   A  Class  Member  timely  and  properly
                    exercising  an  Intermediate  Opt-Out  right  may  not  seek
                    punitive, exemplary, or any multiple damages against the AHP
                    Released Parties or the Non-AHP Released Parties;  provided,
                    however, as consideration for being a Non-AHP Released Party
                    and for  receiving  the benefit of this waiver of  punitive,
                    exemplary,  and multiple damages, the Non-AHP Released Party
                    must agree in writing not to assert any defense based on any
                    statute of limitations or repose, the doctrine of laches, or
                    any other defense predicated on the failure to timely pursue
                    the  claim,  any  defense  based on  "splitting"  a cause of
                    action,  any defense based on any release signed pursuant to
                    the Settlement Agreement,  and/or any other defense based on
                    the  existence of the  Settlement  Agreement,  except to the
                    extent  provided  herein;  and provided  further that if the
                    Non-AHP Released Party so agrees,  then the Class Member may
                    not  recover  more  than the total  amount  of  compensatory
                    damages  he or  she is  entitled  to  from  all  persons  or
                    entities in connection  with any claimed injury arising from
                    his/her use of Diet Drugs,  except where such  limitation is
                    inconsistent  with applicable law. A Class Member timely and
                    properly  exercising an  Intermediate  Opt-Out right may not
                    use any  previous  verdicts  or  judgments  against  the AHP
                    Released  Parties,  or factual  findings  necessary  to such
                    verdicts or judgments,  for purposes of establishing  claims
                    or facts in order to obtain a verdict  or  judgment  against
                    the  AHP  Released   Parties  under  the  doctrines  of  res
                    judicata, collateral estoppel or other doctrines of claim or
                    issue preclusion. Nor may a Class Member timely and properly
                    exercising an  Intermediate  Opt-Out right seek to introduce
                    into  evidence  against the AHP  Released  Parties,  for any
                    purpose,  such a  verdict,  judgment,  or  factual  finding.
                    Lawsuits  initiated by Class Members who timely and properly
                    exercise  an  Intermediate  Opt-Out  shall be subject to the
                    provisions of Section VIII.F.3.



          4.   BACK-END OPT-OUT

               a.   ELIGIBILITY:

                    (1)  As  to   Matrix-Level   claims   based  upon   valvular
                         regurgitation,  all Diet Drug  Recipients  (other  than
                         those who have entered into AIO  Individual  Agreements
                         pursuant to the Accelerated  Implementation Option) who
                         have been  diagnosed  by a Qualified  Physician  as FDA
                         Positive or as having Mild Mitral  Regurgitation  by an
                         Echocardiogram  performed  between the  commencement of
                         Diet Drug use and the end of the Screening Period,  and
                         who reach a Matrix-Level  Condition after September 30,
                         1999, but before the Matrix  Payment  Cut-Off Date, and
                         their  associated   Representative   and/or  Derivative
                         Claimants,  may  exercise  a  Back-End  Opt-Out  right,
                         provided  that the Class  Member has  registered  or is
                         deemed to have  registered for  settlement  benefits by
                         Date 2. Class  Members who knew prior to September  30,
                         1999, that they had injury to one or more of their left
                         side heart valves and a condition  which would  entitle
                         them to payments  on the  Matrices  may not  exercise a
                         Back-End Opt-Out.

                    (2)  As  to  Matrix-Level   claims  based  upon  Endocardial
                         Fibrosis,   all  Diet  Drug  Recipients  who  have  not
                         received the diagnosis of  Endocardial  Fibrosis from a
                         Qualified Physician by September 30, 1999, and who have
                         subsequently been diagnosed by a Qualified Physician as
                         having Endocardial  Fibrosis by September 30, 2005, and
                         their  associated   Representative   and/or  Derivative
                         Claimants, may exercise a Back-End Opt-Out.

                    (3)  Class   Members  who  are  not   eligible   for  Matrix
                         Compensation  Benefits  may not  exercise  the Back-End
                         Opt-Out right provided by this Settlement.

          b.   METHOD OF  EXERCISE:  Each Class  Member who wishes to exercise a
               right of Back-End Opt-Out must complete,  sign, and timely submit
               written  notice of the Class  Member's  intention to do so in the
               form appended  hereto as Exhibit "8." This written notice must be
               submitted   to   the   Court,    the   Trustees   and/or   Claims
               Administrator(s),  and to AHP,  within 120 days after the date on
               which the Class  Member  first  knows or should have known in the
               exercise of  reasonable  diligence  that the  relevant  Diet Drug
               Recipient  developed  a  Matrix-Level  Condition  or by  Date  2,
               whichever is later. In that notice, the Class Member must clearly
               express his or her decision to exercise a Back-End Opt-Out right,
               certify that he or she is eligible to do so, and  acknowledge  an
               understanding of the Settlement  rights and benefits that will be
               relinquished  by the  exercise of the Back-End  Opt-Out.  A Class
               Member may not exercise a Back-End  Opt-Out right after  claiming
               any Matrix Compensation Benefits.

          c.   EFFECT OF  EXERCISE:  The  Back-End  Opt-Out  is  subject  to the
               following  provisions.  A Class  Member who  timely and  properly
               exercises a Back-End Opt-Out may pursue all of his or her Settled
               Claims  (except for those claims set forth in  subparagraphs  (e)
               and (g) of Section I.53), against the AHP Released Parties and/or
               the Non-AHP Released Parties, but may only assert a claim against
               the AHP Released  Parties and/or the Non-AHP  Released Parties as
               follows:  (i)  if  such  person  has  opted  out by  reason  of a
               Matrix-Level Condition of one or more heart valves diagnosed by a
               Qualified Physician as FDA Positive or Mild Mitral  Regurgitation
               by an  Echocardiogram  performed between the commencement of Diet
               Drug use and the end of the  Screening  Period,  such lawsuit may
               only  assert a claim  based on that  heart  valve or  valves  and
               condition;  and (ii) if such  person  has  opted out by reason of
               Endocardial Fibrosis,  such lawsuit may only assert a claim based
               on  Endocardial  Fibrosis.  If, at any time after a Class  Member
               exercises a Back-End  Opt-Out right, the Class Member initiates a
               lawsuit  seeking  to pursue a Settled  Claim  against  AHP or any
               other Released Party,  the Released Party shall have the right to
               challenge,  in such lawsuit only,  whether the opt-out was timely
               and proper,  including  whether the Class  Member was eligible to
               exercise such an opt-out right. With respect to each Class Member
               who timely and properly  exercises the Back-End Opt-Out right and
               who  initiates  a lawsuit  against  any of the  Released  Parties
               within one year from the date on which the Back-End Opt-Out right
               is  exercised,  the AHP  Released  Parties  shall not  assert any
               defense  based on any  statute  of  limitations  or  repose,  the
               doctrine of laches,  any other defense  predicated on the failure
               to timely pursue the claim,  any defense  based on  "splitting" a
               cause of action, any defense based on any release signed pursuant
               to the  Settlement  Agreement,  and/or any other defense based on
               the existence of the Settlement  Agreement,  except to the extent
               provided herein. A Class Member timely and properly  exercising a
               Back-End  Opt-Out  may  not  seek  punitive,  exemplary,  or  any
               multiple  damages against the AHP Released Parties or the Non-AHP
               Released Parties; provided, however, as consideration for being a
               Non-AHP  Released  Party and for  receiving  the  benefit of this
               waiver of punitive,  exemplary, and multiple damages, the Non-AHP
               Released  Party must agree not to assert any defense based on any
               statute of limitations or repose,  the doctrine of laches, or any
               other  defense  predicated  on the  failure to timely  pursue the
               claim,  any defense based on  "splitting" a cause of action,  any
               defense based on any release  signed  pursuant to the  Settlement
               Agreement, and/or any other defense based on the existence of the
               Settlement  Agreement,  except to the extent provided herein; and
               provided  further that if the Non-AHP  Released  Party so agrees,
               then the Class  Member may not recover more than the total amount
               of compensatory damages he or she is entitled to from all persons
               or entities in connection  with any claimed  injury  arising from
               his/her  use of Diet  Drugs,  except  where  such  limitation  is
               inconsistent  with  applicable  law.  A Class  Member  timely and
               properly  exercising a Back-End  Opt-Out may not use any previous
               verdicts  or  judgments  against  the AHP  Released  Parties,  or
               factual  findings  necessary to such verdicts or  judgments,  for
               purposes  of  establishing  claims  or facts in order to obtain a
               verdict or judgment  against the AHP Released  Parties  under the
               doctrines of res judicata, collateral estoppel or other doctrines
               of claim or issue  preclusion.  Nor may a Class Member timely and
               properly  exercising a Back-End  Opt-Out  right seek to introduce
               into evidence against the AHP Released Parties,  for any purpose,
               such a verdict,  judgment, or factual finding. Lawsuits initiated
               by Class  Members  who  timely and  properly  exercise a Back-End
               Opt-Out shall be subject to the provisions of Section VIII.F.3.


V.   ACCELERATED IMPLEMENTATION OPTION

     A.   All Class Members shall be offered the option of obtaining  settlement
          benefits prior to the Final Judicial  Approval Date (the  "Accelerated
          Implementation  Option" or "AIO")  subject to the  conditions  defined
          below.

     B.   Any Class  Member  may elect the AIO at any time from the  Preliminary
          Approval  Date until the Final  Judicial  Approval Date or, unless AHP
          elects to extend  the offer date  thereafter,  the date on which it is
          determined  that  the  Settlement  Agreement  will not  receive  Final
          Judicial  Approval.  Persons  electing  the AIO will  begin  receiving
          benefits  thereunder  at such time as the Trial Court makes an oral or
          written ruling on the approval or non-approval of the Settlement or at
          such time as AHP exercises its "walkaway  rights"  pursuant to Section
          VII.E hereof. A Derivative  Claimant may not elect the AIO if the Diet
          Drug   Recipient   with  whom  he  or  she  is   associated   (or  the
          Representative  Claimant of the Diet Drug  Recipient)  has not elected
          the AIO.

     C.   In order to elect the AIO, a Class  Member must  complete and sign the
          "PINK FORM" appended to this  Settlement  Agreement as Exhibit "9" and
          submit it to the Trustees and/or Claims  Administrator(s).  Any person
          properly  executing the "PINK FORM" and  delivering it to the Trustees
          and/or  Claims  Administrator(s)  during  the  period  in which AHP is
          offering the AIO,  including any extension of the AIO offer, will have
          entered into an  individual  agreement  with AHP,  separate  from this
          Settlement  Agreement,  under which the parties thereto shall have all
          the same  rights,  benefits  and  obligations  to one  another  as the
          rights,  benefits and obligations accorded to Class Members and to AHP
          under the  Settlement  Agreement,  except  as  provided  below.  Class
          Members will have all the rights, benefits and obligations provided in
          Section IV.A, IV.B, and IV.C, except for Section IV.A.1.b herein.  AHP
          will have all the rights, benefits and obligations provided in Section
          VII., except  subsection E. thereof.  Such executed and delivered PINK
          FORMS shall be referred to as "Individual Agreements."

     D.   Such  Individual  Agreements  shall be  effective  prior to the  Final
          Judicial Approval Date and, even if AHP exercises its "walkaway right"
          under Section VII.E, the Individual  Agreements  entered into prior to
          the date of such exercise shall nevertheless be binding and effective.
          If AHP does not  exercise  its  "walkaway  right," and the  Settlement
          Agreement  with the  Settlement  Class does not receive Final Judicial
          Approval  or is  terminated  for any  other  reason,  such  Individual
          Agreements shall nevertheless continue to be effective and binding.

     E.   No person  exercising  an Initial  Opt-Out  right will be  eligible to
          enter into an Individual  Agreement,  unless such Initial  Opt-Out has
          been revoked with AHP's consent  pursuant to Section  IV.D.2.d hereof.
          Persons  signing  Individual  Agreements  will,  by entering into such
          Individual   Agreements,   knowingly  and   affirmatively   waive  all
          Intermediate and Back-End Opt-Out rights otherwise provided for by the
          Settlement  Agreement  regardless  of  whether  or not the  Settlement
          Agreement  receives  Final  Judicial  Approval.   Notwithstanding  the
          preceding sentence, Class Members who enter into Individual Agreements
          pursuant to the Accelerated  Implementation Option will be eligible to
          exercise the Financial  Insecurity  Opt-Out Right described in Section
          III.E.9 above.  In addition,  such persons will agree not to object to
          approval of the  Settlement  by the Court and will agree not to appeal
          from  Trial  Court  Approval.  The  Individual  Agreements  shall also
          provide for a  Screening  Period to commence on or about the AIO Start
          Date and to conclude 12 months after the date on which the  Settlement
          Agreement  obtains Final Judicial  Approval or the date on which it is
          determined  that  the  Settlement  Agreement  will not  receive  Final
          Judicial  Approval  or  is  otherwise   terminated.   Persons  signing
          Individual Agreements pursuant to the AIO shall also agree to be bound
          by the provisions contained in Sections VII.C.1 through VII.C.4 herein
          with  respect to the  protection  of AHP from  claims by  Non-Settling
          Defendants,  notwithstanding  the absence of any order  enjoining  and
          barring all Non-Settling Defendants from commencing or prosecuting any
          claim against AHP or any other Released Party for contribution  and/or
          non-contractual  indemnity  as set  forth  in  Section  VII.C.1.a  and
          Section VII.C.2 herein.

     F.   After  Trial Court  Approval  or in the event Trial Court  Approval is
          denied and an appeal from that denial is taken in a timely manner, but
          prior to the Final Judicial  Approval  Date, the following  provisions
          shall apply:

          1.   Fund A benefits for individuals accepting the AIO will be payable
               only out of Fund A of the Settlement  Trust and AHP's  obligation
               to make  payments to Fund A for this and any other  purpose shall
               be unchanged from that set forth in Section III.B. hereof;

          2.   Fund B benefits for eligible  individuals  accepting the AIO will
               be payable only out of Fund B of the Settlement Trust.  Beginning
               on the AIO Start Date,  the  Trustees may request in writing on a
               monthly basis (each a "Request for Fund B AIO  Payment")  payment
               of an amount  (such  amount  being  referred  to as a "Fund B AIO
               Deposit")   to  pay  claims  for  Fund  B  benefits  by  eligible
               individuals  who have  accepted  the AIO which have not been paid
               due to an  insufficient  cash  balance  in  Fund B and to pay the
               reasonable costs of administration associated with providing such
               benefits.  AHP  shall  pay  the  Fund  B AIO  Deposit  amount  so
               requested  no later  than 15 days  after  the  date on which  AHP
               receives  from the  Trustees  a  Request  for Fund B AIO  Payment
               requesting such Fund B AIO Deposit;  provided however, that AHP's
               obligation  to pay Fund B Deposits  shall at all times be limited
               to the Adjusted Maximum  Available Fund B Amount.  The payment of
               attorneys'  fees by AHP in the  circumstances  described  by this
               paragraph  shall  be  in  accordance  with  Sections   VIII.E.2.,
               VIII.E.3. and VIII.E.4.

     G.   In the event of Final  Judicial  Approval,  all benefits due under the
          AIO shall be paid from Fund A or Fund B, as applicable,  and AHP shall
          continue to have  obligations as set forth in Sections III.B and III.C
          hereof to make  payments  to Fund A and Fund B, but AHP shall  have no
          further  obligation to make any Fund B AIO Deposits to Fund B pursuant
          to  Section  V.F  above  for the  payment  of such AIO  benefits.  All
          Individual  Agreements  shall be  administered  after  Final  Judicial
          Approval in all respects as if they were part of the Settlement, other
          than as set forth in Section V.E hereof;  provided,  however, that all
          persons who have entered into Individual Agreements shall be deemed to
          have registered for all benefits under the Settlement Agreement.  Such
          persons  will  be  subject  to  the  requirements  for  submission  of
          documentation  and other  evidence to establish  their  entitlement to
          settlement  benefits,  including  but not limited to submission of the
          "GREEN FORM" in order to claim Matrix Compensation Benefits.

     H.   If  Final  Judicial  Approval  is not  obtained  or if the  Settlement
          Agreement  is  terminated  by  AHP  for  any  reason,   the  following
          provisions shall apply with respect to the Individual Agreements which
          have been entered into pursuant to the AIO:

          1.   The Settlement Trust shall not automatically terminate, but shall
               remain in effect to administer the Individual Agreements, subject
               to Sections V.H.2, V.H.3, V.H.4 and V.H.5 hereof.

          2.   Notwithstanding  the  provisions of Section V.H.1 hereof,  within
               five  Business  Days  after  the  date on  which  Final  Judicial
               Approval  is  not  obtained  or  the  date  on  which  Settlement
               Agreement is terminated for any other reason,  the Trustees shall
               transfer to AHP all amounts in the Settlement Trust after payment
               of any  charges  and  expenses  which  the  Settlement  Agreement
               expressly  authorized  or required to be  incurred  and  expended
               prior  thereto,  including  any  amounts  expended  to  assist in
               seeking  Final  Judicial  Approval,  except  that the Trust shall
               retain the sum of $50 million and any additional amount which the
               Trustees  reasonably  determine  to be required to provide Fund A
               and  Fund B  benefits  to  individuals  who  have  qualified  for
               benefits  pursuant  to  Individual  Agreements  but  have not yet
               received them. Thereafter,  and subject to any changes negotiated
               or determined by arbitration pursuant to Sections V.H.4 and V.H.5
               hereof, AHP shall make payments to the Trust on a quarterly basis
               of amounts  required  by the Trust to  provide  Fund A and Fund B
               benefits to  individuals  who have  qualified  for such  benefits
               pursuant to Individual  Agreements but have not yet received them
               and  to  maintain  a $50  million  Administrative  Reserve.  Such
               quarterly  payments  shall be based upon an AIO Fiscal Year.  For
               this purpose,  AHP agrees to pay into the  Settlement  Trust such
               amount as the Trustees may request in writing on such a quarterly
               basis, no later than 15 days after the date on which the Trustees
               provide  AHP with such a  quarterly  request,  subject to Section
               V.H.3 below.

          3.   AHP's   obligations  to  make  payments  pursuant  to  Individual
               Agreements,  including  but not  limited to payments to the Trust
               pursuant to Section  V.F and  pursuant  to Section  V.H.2  above,
               shall be subject in the aggregate to the same maximum limitations
               on its  obligations  as would have been  applicable to its Fund A
               and Fund B obligations to the Settlement Trust had the Settlement
               received  Final  Judicial  Approval,  subject  to  the  following
               modifications:

               a.   The payment  amounts  specified in Section  III.B.1.  hereof
                    shall be deemed  to be AHP's  maximum  aggregate  obligation
                    pursuant  to  all  Individual   Agreements  to  pay  for  or
                    otherwise provide benefits or other amounts which would have
                    been payable from Fund A had Final  Judicial  Approval  been
                    obtained and for the cost of administration thereof.

               b.   In calculating the Adjusted Maximum  Available Fund B Amount
                    (i) the AIO Fiscal  Year shall be used in lieu of the Fiscal
                    Year;  and (ii) no  deduction  shall be made for any Credits
                    pursuant  to  Section  VII.A  or  any  Cross-Claim   Credits
                    pursuant to Section VII.C hereof.

          4.   During  the  60-day  period  following  the  termination  of  the
               Settlement  Agreement,  AHP and the Class Counsel shall engage in
               good faith negotiations with respect to a mechanism to administer
               the  Individual  Agreements  in a manner  designed to assure that
               individuals electing the AIO have the same rights and benefits as
               the rights and  benefits  accorded  to Class  Members  under this
               Agreement  (except as provided in Section V.E hereof);  to reduce
               the cost of administering the Individual  Agreements to an amount
               which is reasonable in relation to the number of such  agreements
               which have been entered into;  and to assure that AHP obtains the
               most favorable tax treatment available under those circumstances,
               and to assure that AHP receives all  information  requested by it
               to permit it to take  appropriate  tax  deductions  and otherwise
               calculate its taxes.  Such  negotiations  shall address,  without
               limitation, the following matters:

               a.   whether a  different  mechanism  other  than the  Settlement
                    Trust should be established for administering the Individual
                    Agreements;   whether  such  an  alternative   mechanism  is
                    necessary to reduce the cost of administering the Individual
                    Agreements  to an amount which is  reasonable in relation to
                    the number of such agreements  which have been entered into;
                    or whether  the  Settlement  Trust  shall be retained as the
                    mechanism for administering the Individual  Agreements,  but
                    with  changes  in its  structure  or level of  expenditures;
                    provided  however that the Settlement  Trust shall remain in
                    effect,  as modified in accordance  with Sections  V.H.2 and
                    V.H.3 above,  unless and until such  changes or  alternative
                    mechanisms are agreed upon pursuant to this Section V.H.4 or
                    are determined pursuant to Section H.5;

               b.   whether  and  to  what  extent  an  alternative   means  for
                    resolving  disputes in the  administration of the Individual
                    Agreements,  including  but not  limited to  disputes  as to
                    whether or not AHP has failed to make any required  payment,
                    should be used in lieu of the resolution of such disputes by
                    the Court;

               c.   whether  and to what  extent  changes  should be made to the
                    Security Fund structure and terms  (including a reduction in
                    the amount of collateral  and the treatment of the Financial
                    Insecurity  Opt-Out  Right)  in light of the  number of such
                    agreements which shall have been entered into and to reflect
                    the different circumstances then in effect;

               d.   in the event that the  Settlement  Trust is retained for the
                    purpose of  administering  the  Individual  Agreements,  the
                    amount by which the Administrative  Reserve is to be reduced
                    to reflect the reasonable  administrative needs of the Trust
                    for the purpose of administering the Individual  Agreements,
                    which shall be  reasonable in relation to the number of such
                    agreements which have been entered into.

          5.   In the event  that  Class  Counsel  and AHP are not able to reach
               agreement  as to any or all of the matters  described  in Section
               V.H.4, such matters shall be resolved by binding arbitration by a
               panel of three arbitrators, one of whom shall be selected by AHP,
               one of whom shall be selected  by Class  Counsel and the third of
               whom shall be  selected  by the first two such  arbitrators.  The
               cost of such arbitration shall be paid by the Settlement Trust as
               an  administrative  expense.  Such arbitration shall be conducted
               under the rules of the American Arbitration Association and shall
               be  concluded in no more than 60 days after the end of the 60-day
               period  referred  to  in  Section  V.H.4  above,   including  the
               rendering of a decision by the arbitrators.

     I.   If AHP exercises its "walkaway right" under Section VII.E hereof,  the
          Individual  Agreements  previously  entered into shall nevertheless be
          binding  and  effective  on AHP and the  other  parties  thereto.  The
          exercise  of  the  "walkaway   right"  by  AHP  will  not  affect  its
          obligations  to those Class Members who have accepted the AIO prior to
          AHP's exercise of its "walkaway right" or during any subsequent period
          in which AHP  continues  to offer the AIO,  nor those  Class  Members'
          obligations to AHP thereunder.

     J.   The Parties  shall ask the Court to supervise  the award of attorneys'
          fees relating to the  Individual  Agreements,  as set forth in Section
          VIII.E hereof,  whether or not the Settlement  receives Final Judicial
          Approval.

VI.      CLAIMS ADMINISTRATION

     A.   THE INTERIM  ESCROW AGENT,  INTERIM  CLAIMS  ADMINISTRATOR(S),  CLAIMS

          select an  Interim  Escrow  Agent,  such  selection  being  subject to
          approval  by the  Court.  Until  such time as the Court  approves  the
          appointment  of Trustees,  the Interim  Escrow Agent shall have all of
          the rights and  responsibilities  of the Trustees under the Settlement
          Agreement  with  regard to the receipt and  investment  of  Settlement
          Funds and any  payments  which AHP is required to make to the Trustees
          shall be paid to the Interim Escrow Agent.

     2.   In  connection  with their  request  for  Preliminary  Approval of the
          Settlement,  AHP and the Class Counsel Representative(s) shall request
          that the Court  approve  the  appointment  of two (2)  Interim  Claims
          Administrators. The Interim Claims Administrators will be nominated by
          the Parties,  and each  nomination will be subject to agreement of the

          agreement of AHP and the Class Counsel Representative(s).  Four (4) of
          the  nominees  shall be subject to the approval by the Judges who will

          Agreement,  and the Trustees who shall serve until  December 31, 2004,
          shall  be  designated  as such on the  signature  pages  of the  Trust
          Agreement.  Beginning on January 1, 2005,  the Trust will be comprised
          of three (3) Trustees until the termination of the Trust.  All nominee
          Trustees  shall be subject to the approval of and  appointment  by the
          Federal  District Court.  AHP and the Class Counsel  Representative(s)
          shall use their best  efforts  to assure  that such  Trustees  will be
          appointed within 60 days of this Settlement Agreement.  If any nominee
          is not approved,  the Parties shall jointly  nominate another nominee,
          who  will  be  subject  to  agreement  of AHP and  the  Class  Counsel
          Representative(s).  If any  vacancy  occurs  among the  Trustees,  the
          successor  Trustee,  if any,  shall be  selected  in  accordance  with
          Article 3.06 of the Trust Agreement, subject to approval of the Court.

     4.   The Interim Escrow Agent,  Interim Claims  Administrator(s),  Trustees
          and Claims Administrator(s), shall have the following qualifications:

          a.   The  Interim   Claims   Administrator(s),   Trustees  and  Claims

               disclosure   of  any  and  all   disqualifications   under   this
               subsection,  said  disclosed  disqualifications  may be waived in
               writing  by the  Parties  to this  Agreement,  subject  to  Court
               approval.

     5.   The rights and duties of the Interim  Escrow  Agent shall be set forth
          in an escrow  agreement  substantially  in the form appended hereto as
          Exhibit "10."

     6.   Until  the   effective   date  of  the  Trust,   the  Interim   Claims
          Administrators  shall jointly  exercise all of the functions which are
          to be exercised by the Claims  Administrator(s)  and/or Trustees under
          the terms of this Settlement  Agreement,  except those functions which
          will be exercised by the Interim  Escrow  Agent.  Each Interim  Claims
          Administrator  that was or is a party,  or is  threatened to be made a
          party,  to any  threatened,  pending,  or  completed  action,  suit or
          proceeding of any kind, whether civil,  administrative or arbitrative,
          by reason of such Interim Claims Administrator being or having been an
          Interim  Claims  Administrator,  shall  be  indemnified  by the  Trust
          against  expenses,  costs and fees of  attorneys,  judgments,  awards,
          costs,  amounts  paid in  settlement,  and  liabilities  of all  kinds
          incurred by such Interim Claims  Administrator  in connection  with or
          resulting from such action,  suit, or proceeding if he or she acted in
          good  faith  and  in  a  manner  such  Interim  Claims   Administrator
          reasonably  believed to be in or not opposed to the best  interests of
          the Trust  and/or  the  Interim  Escrow  established  pursuant  to the
          Interim  Escrow  Agreement  contemplated  in this  Section  VI.A.  Any
          indemnification  under this  Section  VI.A.6 shall be made only upon a
          determination by the Court that indemnification of such Interim Claims
          Administrator  is proper in the  circumstances.  Reasonable  expenses,
          costs,  and fees of  attorneys  incurred by or on behalf of an Interim
          Claims  Administrator  in  connection  with any such action,  suit, or
          proceeding,  whether civil, administrative or arbitrative, may be paid
          by the Trust in advance of the final disposition  thereof upon receipt
          of an undertaking by or on behalf of such Interim Claims Administrator
          to repay such amount  unless it shall be  determined  ultimately  that
          such  Interim   Claims   Administrator   or  former   Interim   Claims
          Administrator  is  entitled  to be  indemnified  by the Trust.  If any
          disbursements  are  required to be made for  indemnification  purposes
          pursuant to this  Section  VI.A.6 prior to the  effective  date of the
          Trust,  and are ordered to be paid by the Court,  the  Interim  Escrow
          Agent shall have the authority to make  disbursements from the Interim
          Escrow  for such  purposes.  Each  Interim  Claims  Administrator  may
          purchase  and  maintain  reasonable  amounts  and  types of  insurance
          against  liability  asserted against or incurred by such individual in
          that  capacity or arising from his or her status as an Interim  Claims
          Administrator.  Each Interim Claims  Administrator  shall have a prior
          lien upon the Trust  and the  Interim  Escrow  Account  to secure  the
          payment of any amounts  payable to such Interim  Claims  Administrator
          pursuant to this Section  VI.A.6.  The Interim  Claims  Administrators
          shall not be required to post any bond or other form of surety  unless
          otherwise ordered by the Court.

     7.   In addition to the duties,  obligations  and  procedures  described in
          this Settlement Agreement,  the Interim Claim(s)  Administrator(s) (if
          required),  Claims Administrator(s) and Trustees shall hire personnel,
          including personnel qualified to provide expert medical advice.

     8.   Until the effective date of the Trust:

          a.   Disbursements for purposes of paying claims or providing benefits
               under  the  Settlement  Agreement  shall  be made by the  Interim
               Escrow  Agent  subject to the  direction  of the  Interim  Claims
               Administrators; and

          b.   Disbursements  for purposes of claims  administration,  including
               the cost of providing  notice to the Settlement  Class,  shall be
               made by the Interim  Escrow Agent subject to the joint  direction
               of AHP and Class Counsel.  All  disbursements  will be subject to
               review and approval by the Court.

     9.   As promptly as possible,  after the effective  date of the Trust,  for
          purposes of administering the Settlement Trust:

          a.   Control  over  Fund A and  Fund B  shall  be  transferred  by the
               Interim Escrow Agent to the Trustees and upon such transfer,  the
               Interim Escrow Agent shall cease to have any  responsibility  for
               the future receipt,  preservation,  maintenance,  investment, and
               disbursement of the Settlement funds;

          b.   The Trustees shall have  responsibility for each matter entrusted
               to the "Trustees and/or Claims  Administrator(s)" under the terms
               of  the   Settlement   Agreement.   Until  such  time  as  Claims
               Administrator(s)   are   appointed  and  approved  by  the  Court
               according to Section  VI.A.9.c  below,  the Trustees may delegate
               any portion of their responsibility for claims  administration to
               the Interim Claims Administrator(s);

          c.   The Trustees  shall have  responsibility  for  appointing  Claims
               Administrator(s)  within  120  days  of the  date  on  which  the
               Trustees are appointed by the Court,  and the  appointment of the
               Claims  Administrator(s)  shall be  subject  to  approval  of the
               Court.  At  the  time  of  such  approval,   the  Interim  Claims
               Administrator(s) shall have no further duties or responsibilities
               under the Settlement.

     10.  The Trustees  (and the Interim  Claims  Administrator(s))  and Interim
          Escrow  Agent  prior to the  effective  date of the Trust  shall  make
          reports to the Court, AHP, and Class Counsel as follows:

          a.   Annual Reporting Obligations

               (1)  On an annual (calendar year) basis, the Trustees shall cause
                    an audit to be  performed by a Certified  Public  Accountant
                    upon the calendar year  financial  statements of each of the
                    following  (each  financial   statement  being  prepared  in
                    accordance with generally  accepted  accounting  principles)
                    and shall  issue a report  stating  the  result of each such
                    audit:

                    (a)  the   Settlement   Trust  and  each  Fund   established
                         thereunder;

                    (b)  the Security Fund; and

                    (c)  each   escrow   account   then  in   effect   hereunder
                         (including, as to the Security Fund Escrow Account, the
                         amounts  transferred  from the  Security  Fund  upon an
                         Uncured Failure to Make Payment).

               (2)  On an annual basis based on the calendar  year, the Trustees
                    shall provide AHP with  information  sufficient to allow AHP
                    to calculate  in a timely  fashion its  estimated  taxes and
                    taxes in connection  with payments made by AHP to the Trust,
                    including without limitation the actual payments made by the
                    Trust.

               (3)  The Trustees  shall provide  annual  reports for each Fiscal
                    Year  to be sent to AHP  and to  Class  Counsel,  reporting,
                    among other appropriate items, the following:

                    (i)  the total  amount paid out of each of Fund A and Fund B
                         for each category of benefit  payable by each such Fund
                         for  that  Fiscal  Year  and   cumulatively   from  the
                         Preliminary Approval Date;

                    (ii) the  amounts   incurred  by  the  Settlement  Trust  in
                         administrative  expenses and for any other  purpose for
                         that Fiscal Year and cumulatively  from the Preliminary
                         Approval  Date,  and how such  disbursements  have been
                         allocated between Fund A and Fund B;

                    (iii)the amount of cash and other liquid  assets held by the
                         Settlement Trust at the end of that Fiscal Year;

                    (iv) the Trustees' calculation of the Fund B amounts paid by

     C.   CLAIMS ADMINISTRATION AND CRITERIA FOR BENEFITS DETERMINATIONS.

          1.   ECHOCARDIOGRAM CRITERIA.

               a.   Where  a Diet  Drug  Recipient  has  had  an  Echocardiogram
                    between the  commencement of Diet Drug use and September 30,
                    1999, the results of that Echocardiogram as contained in the
                    written report issued by a Qualified Physician shall be used
                    by the  Trustees/Claims  Administrator(s)  to determine  the
                    level of mitral and/or  aortic  valvular  regurgitation  for
                    that   Diet   Drug   Recipient   as  of  the   date  of  the
                    Echocardiogram    for    purposes   of   Fund   A   benefits
                    determinations  under the Settlement  Agreement,  except (i)
                    where the  report  of the  Echocardiogram  does not  clearly
                    state the level of  valvular  regurgitation  for the  mitral
                    and/or  aortic  valves or (ii)  where in an audit  conducted
                    pursuant  to  Section  VI.E,  it  is  determined   that  the
                    conclusions  of the written  report are not supported by the
                    videotape or disk of the Echocardiogram or a Board-Certified
                    Cardiothoracic Surgeon.

                    Such an  Echocardiogram  shall not be used to qualify a Diet
                    Drug Recipient for Matrix Compensation Benefits unless, upon
                    re-reading,  it is  determined  (i) that prior to the end of
                    the  Screening  Period,  the  Diet  Drug  Recipient  met the
                    definition  for "FDA  Positive" set forth in Section  I.22.b
                    and (ii) the  Echocardiogram  met the  criteria set forth in
                    Section VI.C.1.b below.  Such a determination may be made by
                    the Trustees and/or Claims  Administrator(s) upon submission
                    of a GRAY FORM  (appended  hereto as Exhibit "20") which has
                    been completed by a Board-Certified Cardiologist.

               b.   Each  Echocardiogram  performed  after  September  30, 1999,
                    which is used to determine  whether the  condition of a Diet
                    Drug Recipient qualifies a Class Member for Fund A or Fund B
                    (Matrix) settlement benefits, shall be one which was:

                    (1)  conducted in accordance with the standards and criteria
                         as outlined in Feigenbaum (1994)39 or Weyman (1994);40

                    (2)  evaluated  following  the  grading  system of  valvular
                         regurgitation defined in Singh (1999);41

                    (3)  conducted by a Diagnostic  Cardiac  Sonographer  who is
                         able to  produce  and  evaluate  ultrasound  images and
                         related  data  used by  physicians  to render a medical
                         diagnosis; and

                    (4)  conducted  under  the  supervision  of,  and  read  and
                         interpreted  by,  a  Board-Certified   Cardiologist  or
                         Board-Certified  Cardiothoracic  Surgeon  with  level 2
                         training  in   echocardiography  as  specified  in  the
                         Recommendations    of   the    American    Society   of
                         Echocardiography  Committee  on  Physician  Training in
                         Echocardiography.42

          c.   A Diet Drug  Recipient who  demonstrates  to the Trustees  and/or
               Claims  Administrator(s)  that  he or she  had an  Echocardiogram
               conducted between September 30, 1999 and the date of commencement
               of Class Notice which a Qualified  Physician  reported as showing
               that  he or she  had  FDA  Positive  regurgitation  shall  not be
               disqualified   from   receiving   settlement   benefits   if  the
               Echocardiogram  does not meet all of the  requirements of Section
               VI.C.1.b above.

          d.   A claimant who  qualifies  for a particular  Matrix  payment,  by
               virtue  of a  properly  interpreted  Echocardiogram  showing  the
               required levels of  regurgitation  and/or  complicating  factors,
               after exposure to fenfluramine and/or dexfenfluramine,  shall not
               be  disqualified  from receiving that Matrix payment in the event
               that a subsequent  Echocardiogram  shows that the required levels
               of  regurgitation  and/or  complicating  factors  are  no  longer
               present.

          a.   Each Claim for Benefits under the Settlement  Agreement  shall be
               made on one of two forms  signed and  submitted  to the  Trustees
               and/or Claims Administrator(s), as follows:

               (1)  The "PINK FORM"  appended  to the  Settlement  Agreement  as
                    Exhibit "9" shall be used by Class Members who want to elect
                    the AIO; and

               (2)  The "BLUE FORM"  appended  to the  Settlement  Agreement  as
                    Exhibit  "21" shall be used by all other  Class  Members who
                    wish to make a claim for the  benefits  available  under the
                    Settlement Agreement.

          b.   Submission  of a PINK FORM or BLUE  FORM that has not been  fully
               completed  shall be sufficient to "register" the Class Member for
               benefits, provided, however, that the missing information must be
               submitted  in order for the Class  Member to receive any benefits
               under this Settlement Agreement.

          c.   In  addition,  each  person  who wants to make a claim for Matrix
               Compensation  Benefits  under  Section  IV.B  of  the  Settlement
               Agreement or pursuant to the AIO must  complete and submit to the
               Trustees and/or Claims Administrator(s) the "GREEN FORM" which is
               appended to this Settlement Agreement as Exhibit "22."

          d.   In order to complete the submission of a Claim and to qualify for
               any benefits  under the Settlement  Agreement,  each Class Member
               must  submit  documentary  proof to the  Trustees  and/or  Claims
               Administrator(s)  of the  period of time for which the Diet Drugs
               Pondimin(R) and/or Redux(TM) were prescribed and dispensed to the
               Diet Drug  Recipient who is the subject of the Claim.  This proof
               must include one of the following:

               (1)  If the diet drug was  dispensed by a pharmacy,  the identity
                    of each pharmacy that  dispensed Diet Drugs to the Diet Drug
                    Recipient,   including  its  name,  address,  and  telephone
                    number, and a copy of the prescription  dispensing record(s)
                    from each  pharmacy,  which  should  include the  medication
                    name,  quantity,  frequency,  dosage  and  number of refills
                    prescribed,    prescribing    physician's   name,   assigned
                    prescription number,  original fill date and each subsequent
                    refill date; or,

               (2)  If the diet drug was  dispensed  directly by a physician  or
                    weight  loss   clinic,   or  the   pharmacy   record(s)   is
                    unobtainable,  the identity of each  prescribing  physician,
                    including the prescribing  physician's  name,  address,  and
                    telephone  number  and  a  copy  of  the  medical  record(s)
                    prescribing  or  dispensing  the diet  drug(s).  The medical
                    record(s) must include  records which identify the Diet Drug
                    Recipient,  the Diet Drug name, the date(s) prescribed,  the
                    dosage, and duration the drug was prescribed or dispensed;

               (3)  If  the   pharmacy   records   and   medical   records   are
                    unobtainable, an affidavit under penalty of perjury from the
                    prescribing physician or dispensing pharmacy identifying the
                    Diet Drug  Recipient,  the drug(s)  prescribed or dispensed,
                    the  date(s),  quantity,  frequency,  dosage  and  number of
                    prescriptions or refills of the Diet Drug(s).

          e.   In order to complete  the  submission  of a Claim and qualify for
               Fund A benefits  under the  Settlement  Agreement,  where a Class
               Member relies on a result of an  Echocardiogram to establish that
               a Diet Drug Recipient had FDA Positive levels of regurgitation by
               the end of the  Screening  Period and where  that  Echocardiogram
               took  place  between  the  commencement  of  Diet  Drug  use  and
               September  30,  1999,  the Class Member must provide the Trustees
               and/or Claims  Administrator(s)  with a copy of the report of the
               results of the  Echocardiogram  and the  videotape or disk of the
               Echocardiogram.  In order to complete the  submission  of a Claim
               and qualify for Matrix Compensation Benefits under the Settlement
               Agreement,  where  a  Class  Member  relies  on a  result  of  an
               Echocardiogram  to establish  that a Diet Drug  Recipient had FDA
               Positive levels of regurgitation or Mild Mitral  Regurgitation by
               the end of the  Screening  Period and where  that  Echocardiogram
               took  place  between  the  commencement  of  Diet  Drug  use  and
               September  30,  1999,  the Class Member must provide the Trustees
               and/or Claims  Administrator(s)  with a copy of the report of the
               results of the  Echocardiogram  and the  videotape or disk of the
               Echocardiogram and a certification from a Qualified  Physician on
               the GRAY FORM which is appended to the  Settlement  Agreement  as
               Exhibit  "20" or a  certification  regarding  the  results of the
               Echocardiogram  on  the  GREEN  FORM  which  is  appended  to the
               Settlement  Agreement as Exhibit "22.".  If the Class Member does
               not have custody of such videotape or disk, the Class Member must
               submit an executed  authorization  which will allow the  Trustees
               and/or Claims  Administrator(s)  to obtain a videotape or disk of
               the Echocardiogram from the physician or health care provider who
               has  custody  of  such  videotape  or  disk  as  a  condition  to
               considering  the  Class  Member's  Claims  for  Benefits.  If the
               videotape  or disk is no longer in  existence,  the Class  Member
               must supply an affidavit under penalty of perjury from the person
               who last had custody of the  videotape  or disk  stating that the
               videotape or disk is no longer in existence  and  describing  the
               circumstances under which it came to be misplaced or destroyed.

          f.   In order to complete  the  submission  of a Claim and qualify for
               benefits  under the  Settlement  Agreement,  where a Class Member
               relies on the results of an  Echocardiogram  to establish  that a
               Diet Drug  Recipient  had FDA  Positive  regurgitation  levels of
               regurgitation  or  Mild  Mitral  Regurgitation  by the end of the
               Screening Period and where that  Echocardiogram  took place after
               September  30,  1999,  and where that  Echocardiogram  took place
               outside of the  Screening  Program,  the Class Member must report
               the results of the  Echocardiogram  to the Trustees and/or Claims
               Administrator(s)   in  the  form  of  a   certification   from  a
               Board-Certified  Cardiologist  on the GRAY FORM which is appended
               to the Settlement  Agreement as Exhibit "20," or a  certification
               regarding  the  results of the  Echocardiogram  on the GREEN FORM
               which is appended to the  Settlement  Agreement as Exhibit  "22,"
               and provide the Trustees  and/or Claims  Administrator(s)  with a
               copy of the  videotape or disk which  reflects the results of the
               Echocardiogram. If the Class Member does not have custody of such
               videotape  or disk,  the Class  Member  must  submit an  executed
               authorization   which  will  allow  the  Trustees  and/or  Claims
               Administrator(s)   to   obtain  a   videotape   or  disk  of  the
               Echocardiogram from the physician or health care provider who has
               custody of such  videotape or disk as a condition to  considering
               the Class Member's  Claim for Benefits.  If the videotape or disk
               is no  longer  in  existence,  the Class  Member  must  supply an
               affidavit  under  penalty of perjury from the person who last had
               custody of the  videotape or disk  stating that the  videotape or
               disk is no longer in existence and describing  the  circumstances
               under which it came to be misplaced or destroyed.

          g.   Each    Cardiologist    who   is   responsible   for   performing
               Echocardiograms  pursuant to the Screening Program  provisions of
               the  Settlement  Agreement  shall  report  the  results  of those
               Echocardiograms to the Trustees and/or Claims Administrator(s) on
               the "GRAY FORM" which is appended to the Settlement  Agreement as
               Exhibit "20" and shall supply a copy of the  videotape or disk of
               the results of the Echocardiogram to the Claims  Administrator(s)
               and/or Trustees. If a Class Member submits to the Trustees and/or
               Claims  Administrators a GREEN FORM with the Doctor's  Evaluation
               Form in Part II of such Form (or the  equivalent  section  of the
               GREEN FORM in any  subsequent  printing of such  forms)  properly
               completed  and  signed  by  a  Board-Certified   Cardiologist  or
               Cardiothoracic  Surgeon,  that Class  Member and  Board-Certified
               Cardiologist or Cardiothoracic Surgeon are not required to submit
               a GRAY FORM to report on the same  Echocardiogram  referenced  in
               such GREEN FORM. If, however, a Cardiologist  submits a GRAY FORM
               reporting on an  Echocardiogram  performed on a Class Member,  in
               order to seek Matrix  Compensation  Benefits,  such Class  Member
               must  submit  a  complete  GREEN  FORM,  including  the  Doctor's
               Evaluation  Form in Part II (or its  equivalent in any subsequent
               printings) completed and signed by a Board-Certified Cardiologist
               or Cardiothoracic Surgeon.

          h.   In order to complete  the  submission  of a claim and qualify for
               benefits  under the Settlement  Agreement,  each Class Member who
               submits a claim as a  Representative  Claimant  must  supply  the
               Trustees and/or Claims  Administrator(s)  with written proof that
               such  person  has  legal  authority  to act  in a  representative
               capacity.

          i.   In order to complete  submission of a Claim for  reimbursement of
               the actual  amount paid for an  Echocardiogram  by a Class Member
               pursuant to Sections IV.A.1.b, IV.A.2.b.(2), or IV.A.3.d above, a
               Class Member must submit the following documents:

               (1)  A copy of the report of the Echocardiogram;

               (2)  A copy of the bill or invoice reflecting the charges for the
                    Echocardiogram; and

               (3)  A copy of the cancelled check or other documentary  evidence
                    of the  amount  actually  paid by the Class  Member  for the
                    Echocardiogram.

          j.   In order to complete the  submission of a Claim by a Class Member
               who has ingested Pondimin(R) and/or Redux(TM) for 60 days or less
               to receive an Echocardiogram and interpretive physician visit for
               compassionate and humanitarian reasons pursuant to the provisions
               of Section IV.A.2.b(3),  the Class Member must submit documentary
               proof  supporting  the Claim  that  there are  compassionate  and
               humanitarian  reasons  which would  justify the  Trustees  and/or
               Claims  Administrator(s)  to exercise their discretion to provide
               the Diet  Drug  Recipient  with the  benefit  of a  Transthoracic
               Echocardiogram and associated interpretive physician visit.

          k.   In order to  complete  the  submission  of a claim and qualify to
               receive an Echocardiogram after Trial Court Approval but prior to
               Final Judicial  Approval by reason of "true  financial  hardship"
               pursuant to Section IV.A.3.c of the Settlement Agreement,  a Diet
               Drug   Recipient   must  provide  the  Trustees   and/or   Claims
               Administrator(s)   with  documentary   proof  of  the  Diet  Drug
               Recipient's financial situation including a copy of the Diet Drug
               Recipient's  most  recent  federal  income  tax  return  or other
               documentary  proof of the Diet Drug Recipient's  income where the
               Diet Drug Recipient submits a sworn declaration, under oath, that
               he or she has not filed such tax returns.

     3.   GENERAL CLAIMS PROCESSING PROCEDURES AND THE REGISTRY.

          a.   Within thirty (30) days of the date on which the Trustees  and/or
               Claims Administrator(s) receive a Claim for Benefits from a Class
               Member, the Claims Administrator(s) shall:

               (1)  assign a unique identifying number to the Claim;

               (2)  review the Claim  which has been  submitted,  together  with
                    supporting documentation, and determine whether the Claim is
                    complete or requires a submission of additional  information
                    to make it complete;

               (3)  confirm that any required physician  certification submitted
                    in support of a claim for Matrix  Compensation  Benefits was
                    submitted by a physician  who actually is a  Board-Certified
                    Cardiologist,     Cardiothoracic    Surgeon,    Pathologist,
                    Neurologist or Neurosurgeon; and

               (4)  inform  the  Class  Member,   in  writing,   of  the  unique
                    identifying  number assigned to the Class Member's Claim and
                    the  information  which the Class  Member must submit to the
                    Trustees  and/or Claims  Administrator(s),  if any, in order
                    for the claim to be completed and ready for processing.

                    During the first full twelve (12) calendar months  following
                    the   AIO   Start   Date,   the   Trustees   and/or   Claims
                    Administrator(s)  shall take these actions within sixty (60)
                    days of the date on which they  receive a Claim for Benefits
                    from a Class  Member,  rather  than  the  thirty-day  period
                    stated above.

          b.   With respect to each Claim submitted by a Class Member as part of
               the claims  administration  process,  the Trustees  and/or Claims
               Administrator(s)  shall  afford each Class  Member at least three
               (3)  separate  opportunities  to supply  any  missing  or omitted
               information  and  documentation  which are necessary to support a
               Claim for Benefits under the Settlement Agreement.

          c.   All information submitted by Class Members to the Trustees and/or
               Claims  Administrator(s)  shall  be  recorded  in a  computerized
               database suitable for use with standard medical research software
               such as SAS and for all purposes of claims  administration.  This
               database,  throughout the duration of its use, shall be kept in a
               form  that can be  accessed  and read,  which  may in the  future
               involve, as evolving technology warrants, placing the information
               in a more modern database.

          d.   The database created pursuant to the preceding paragraph shall be
               maintained  as a  "Registry"  for purposes of  administering  the
               Settlement  and for purposes of medical  education  and research.
               After taking appropriate steps to maintain the confidentiality of
               Class Members, the Trustees and/or Claims  Administrator(s) shall
               make the database, or any portion thereof, available to qualified
               scientists,  physicians,  and other  researchers  subject  to the
               following conditions:

               (1)  First,  the Trustees  and/or Claims  Administrator(s)  shall
                    make  the  deidentified43  database  available  only to such
                    persons who:

                    (a)  provide the  Trustees  and/or  Claims  Administrator(s)
                         with written proof of their  training,  qualifications,
                         and   experience  to  conduct   medical  or  scientific
                         research;

                    (b)  provide a research  protocol setting forth the purposes
                         for which  they seek  access to the  Registry/database,
                         their  research  methodology,   source  of  funding,  a
                         description  of how the proposed  research will benefit
                         the Settlement Class and any other information that may
                         be   requested   by   the   Trustees    and/or   Claims
                         Administrator(s);

                    (c)  undertake,  in writing,  to use the  information  which
                         they  receive  from the  Registry/database  solely  for
                         medical,  scientific,  and educational purposes and not
                         to disclose  confidential  information  concerning  any
                         Class   Member   in  the   event   that   they   should
                         inadvertently come into possession of such confidential
                         information through their access to the database;

                    (d)  undertake,  in writing, to provide,  upon completion of
                         the    research,    the    Trustees    and/or    Claims
                         Administrator(s),  the Court,  AHP,  and Class  Counsel
                         with a copy of any published or  unpublished  abstract,
                         article, or report which is based, in whole or in part,
                         on the information contained in the Registry/ database;
                         and

                    (e)  undertake,  in  writing,  not to testify at any time on
                         behalf of any party in any lawsuit  relating to the use

                    setting  forth an opinion to a reasonable  degree of medical
                    certainty that (a) the Diet Drug Recipient has the condition
                    which  qualifies  the Class Member for a  particular  Matrix
                    payment,  including,  where  applicable,  that the causation
                    requirements  applicable  to  conditions  (b)(v)  and (c) of

                    was  not  present  prior  to  usage  of  Pondimin(R)  and/or
                    Redux(TM);  and (c) all the  conditions set forth in Section
                    IV.B.2.d.  which  determine  whether  Matrix  A-1  or B-1 is

               (5)  a   declaration    under   penalty   of   perjury   from   a

                    if applicable;

               (7)  any other  documentation  which the Trustees  and/or  Claims
                    Administrator(s)  are otherwise  authorized to request under
                    this Settlement Agreement; and

               (8)  for  an  Echocardiogram  that  took  place  outside  of  the
                    Screening  Program,  and if not  previously  submitted  in a
                    GREEN FORM, a  certification  from a Qualified  Physician on
                    the GRAY FORM which is appended to the Settlement  Agreement
                    as  Exhibit  "20"  that  the  Diet  Drug  Recipient  met the
                    criteria for having FDA Positive regurgitation as defined in
                    Section  I.22 or Mild  Mitral  Regurgitation  as  defined in
                    Section I.38 prior to the end of the Screening Period.

               The  records  and  information  described  in  (1)  through  (8),
               inclusive,   together  with,  if  applicable,   the   information
               described  in Section  VI.C.4.b  below,  are  referred  to as the
               "Medical  Information."  Subject  to the  provisions  of  Section
               VI.C.4.b,  a Claim for Matrix Compensation  Benefits shall not be
               considered  completed  within the  meaning of Section  VI.C.2 and
               Section  VI.C.4 and ready for  determination  until the  Trustees
               and/or Claims  Administrator(s)  have  received,  either from the
               Class Member or the  healthcare  provider or  applicable  records
               custodian,  all  Medical  Information  and a  properly  and fully
               completed  GREEN FORM (and GRAY FORM, if applicable)  relating to
               such Claim.

          b.   If the Class Member  seeking a Matrix payment is unable to obtain
               the  documentation   described  above  through  the  exercise  of
               reasonable  efforts,  the Trustees  and/or  Claims  Administrator
               shall have the right to consider other  supporting  documentation
               including  but not  limited to  declarations  of other  Qualified
               Physician(s) under penalty of perjury setting forth opinion(s) to
               a  reasonable  degree of medical  certainty  to support the claim
               that the Class Member's condition entitles him or her to a Matrix
               payment,  subject  to review by the Court as set forth in Section
               VIII.D. If this evidence establishes the Class Member's condition
               to   the    satisfaction    of   the   Trustees   and/or   Claims
               Administrator(s),  the Class  Member shall be entitled to receive
               the appropriate Matrix Compensation Benefits.

          c.   Upon  receiving  a claim for Matrix  Compensation  Benefits,  the
               Trustees   and/or  Claims   Administrator(s)   shall  obtain  the
               following information from the Class Member:

               (1)  A copy of any fee agreement between the Class Member and the
                    attorney  representing  that  Class  Member  which  shall be
                    submitted and maintained in confidence;

               (2)  A verified statement of the out-of-pocket  costs incurred by
                    the  Class  Member's  individual  attorney,  which  shall be
                    submitted and maintained in confidence;

               (3)  A written  representation  by the Class  Member or the Class
                    Member's attorney,  made subject to penalties of perjury, as
                    to  whether  or not a  subrogation  lien or  claim  has been
                    asserted with respect to the Class Member's right to receive
                    benefits  under the  Settlement  and, if so, the name of the
                    subrogee; and

               (4)  If the Class Member is a Representative Claimant, such court
                    approvals or authorizations as may be necessary to authorize
                    that person to consummate a Settlement  in a  representative
                    capacity.

               Until the  submission  of all of the  information  referred to in
               Section VI.C.2,  a Claim for Matrix  Compensation  Benefits shall
               not be considered "completed" and ready for determination.

          d.   Subject to the audit  provisions  of this  Settlement  Agreement,
               Section  VI.E  and  Section  VI.F,  the  Trustees  and/or  Claims
               Administrator(s) shall make Matrix Benefits  Determinations based
               upon the Medical  Information  provided to them by an appropriate
               Board-Certified  physician  on  or  with  a  properly  and  fully
               completed GREEN FORM. In making Matrix  Benefits  Determinations,
               if the Trustees  and/or  Claims  Administrator(s)  determine  any
               inconsistency  in the  information  provided in a Claim Form, the
               Trustees and/or Claims  Administrator(s) shall review the Medical
               Information  relating to such Claim to  determine  if the Medical
               Information resolves such inconsistency.

          e.   No earlier than thirty (30) days after AHP receives access to the
               documents   provided  to  AHP  by  the  Trustees   and/or  Claims
               Administrator(s)  pursuant to Section  VI.F.1,  and no later than
               sixty  (60) days after  receiving  a  completed  Claim for Matrix
               Compensation     Benefits,    the    Trustees    and/or    Claims
               Administrator(s) shall make a tentative determination:

               (1)  As  to  whether   the  Class   Member(s)   is   entitled  to
                    compensation  under the  Matrices,  and if so, the amount of
                    compensation to which the individual is entitled,  including
                    an  apportionment   among   Derivative  and   Representative
                    Claimants to the extent necessary;

               (2)  The   amount  of   counsel   fees  to  which  the   attorney
                    representing  the  Class  Member  is  entitled,  making  the
                    appropriate  deduction of 9% to account for the fees paid to
                    Class  Counsel as required by Section  VIII.E.1.b or Section
                    VIII.E.3 of this Agreement, whichever is applicable;

               (3)  The amount of reasonable  out-of-pocket  expenditures  which
                    should be reimbursed to the individual attorney representing
                    the Class Member;

               (4)  The amount to which any  subrogee is entitled in  accordance
                    with the provisions of Section VII.D.2 hereof; and

               (5)  The net amount to which the Class  Member is entitled  after
                    making    appropriate    deductions    for   counsel   fees,
                    reimbursement  of  litigation  expenses,  and payment of all
                    appropriate subrogation liens.

          f.   Immediately  upon  making  the  determination   required  by  the
               preceding paragraph,  the Trustees and/or Claims Administrator(s)
               shall  notify  the Class  Members;  the  attorneys  for the Class
               Members,  if any; and the subrogrees if any, of the determination
               and  provide  them with a period of thirty  (30) days in which to
               contest the tentative determination by the Trustees and/or Claims
               Administrator(s),   and   to   provide   additional   information
               concerning the level of Matrix Compensation Benefits which should
               be paid as well as the  distribution  and  apportionment of those
               benefits.  At the same time as this notice,  the Trustees  and/or
               Claims  Administrators shall also notify AHP of the determination
               required by the preceding paragraph.

          g.   Within sixty (60) days of receiving any explanatory or supporting
               information  pursuant to the preceding paragraph or within ninety
               (90) days of receiving a completed Claim for Matrix  Compensation
               Benefits,   whichever  is  later,   the  Trustees  and/or  Claims
               Administrator(s) shall make a final determination:

               (1)  As to whether the Class  Member is entitled to  compensation
                    under the Matrices,  and, if so, the amount of  compensation
                    to  which  the  Class  Member  is  entitled,   including  an
                    apportionment among Derivative and Representative  Claimants
                    to the extent necessary;

               (2)  The   amount  of   counsel   fees  to  which  the   attorney
                    representing  the  Class  Member  is  entitled,  making  the
                    appropriate  deduction of 9% to account for the fees paid to
                    Class  Counsel as  required  by Section  VIII.E.3 or Section
                    VIII.E.1.b of this Agreement, whichever is applicable;

               (3)  The amount of reasonable  out-of-pocket  expenditures  which
                    should be reimbursed to the individual attorney representing
                    the Class Member;

               (4)  The amount to which any  subrogee is entitled in  accordance
                    with the provisions in Section VII.D hereof; and

               (5)  The net amount to which the Class  Member is entitled  after
                    making    appropriate    deductions    for   counsel   fees,
                    reimbursement  of  litigation  expenses,  and payment of all
                    appropriate subrogation liens.

               At the  same  time as  notice  is  given  to the  affected  Class
               Member(s),   attorney(s),   and/or   subrogees   of   the   final
               determination under Section VI.C.4.g,  the Trustees and/or Claims
               Administrators shall also notify AHP of such final determination.

               During the first full twelve (12) calendar  months  following the
               AIO Start Date, the Trustees and/or Claims Administrator(s) shall
               make this final determination within sixty (60) days of receiving
               any  explanatory  or supporting  information  pursuant to Section
               VI.C.4.f above or within 105 days of receiving a completed  Claim
               for Matrix Compensation Benefits, whichever is later, rather than
               the sixty and ninety day periods stated above.

          h.   Within   fifteen   (15)   days  of   receiving   notice   of  the
               Trustees/Claims Administrators' final determination, the affected
               Class Member(s),  attorney(s),  and/or subrogee(s) may appeal the
               determination  by filing a Notice of Appeal in the form  appended
               hereto as Exhibit "24" with the Trial Court and serving a copy on
               the Trustees and/or Claims Administrator(s).

          i.   In the event of such an appeal,  the Court shall refer the matter
               to Arbitration by a single Arbitrator appointed by the Court from
               a panel of  arbitrators  appointed by the Court for that purpose.
               With  respect  to an appeal  by a Class  Member  relating  to the
               determination of the gross amount of Matrix Compensation Benefits
               to which  the Class  Member is  entitled,  the  Arbitrator  shall
               determine  whether the Trustees  and/or  Claims  Administrator(s)
               have  properly  applied the criteria set forth in the  Settlement
               Agreement  to the  information  submitted  by the Class Member in
               support  of the claim and shall  enter a report  and award  which
               either  affirms  the  decision  of  the  Trustees  and/or  Claims
               Administrator(s)  or directs a different  payment than that which
               was  determined by the Trustees  and/or Claims  Administrator(s).
               With respect to an appeal relating to the distribution of counsel
               fees and costs,  the Arbitrator shall determine the amount of the
               attorneys  fees to which  the  attorney  is  entitled  under  the
               provisions  of the  applicable  state law after  deducting  9% as
               required by Section  VIII.E.1.b of this  Agreement and the extent
               to  which  the  attorney   should   receive   reimbursement   for
               out-of-pocket  costs  from  the  Class  Member's  recovery  under
               applicable  state  law.  In the case of an appeal  relating  to a
               subrogation  issue,  the Arbitrator shall determine the amount to
               which  the  subrogee  is  entitled  to  under  applicable  law to
               consistent  with  the  provisions  of  Section  VII.D.2  of  this
               Agreement.

               The  costs  of  such  Arbitration,  including  the  fees  of  the
               Arbitrator,  shall  be taxed  by the  Arbitrator  in favor of the
               party  who  substantially  prevails  in  the  Arbitration  if the
               Arbitrator  finds  that the  appeal  was taken or  maintained  in
               violation  of  the  standards  set  forth  in  Fed.R.Civ.P.11(b).
               Otherwise,  the  costs of such  Arbitration  shall be paid by the
               Trust.  Any party may  appeal  from the  report  and award of the
               Arbitrator to the Court.

          j.   If there is no appeal initiating an Arbitration process, then the
               decision of the  Trustees  and/or  Claims  Administrator(s)  with
               respect to the gross  amount to be paid on account of a Claim for
               Matrix  Compensation  Benefits shall be final,  unless there is a
               documented  change  in the  physical  condition  of the Diet Drug
               Recipient   after   submission  of  the  claim  which   justifies
               consideration for a greater level of Matrix Compensation Benefits
               than  previously  applied  for  or  justifies  consideration  for
               payment at the same level as previously  applied for by reason of
               a different physical condition than that which was the subject of
               the prior Claim for Benefits by the Class Member.

          k.   If there is no appeal initiating an Arbitration process, then the
               decision of the  Trustees  and/or  Claims  Administrator(s)  with
               respect to the  distribution of any portion of any amount paid on
               account  of a  Claim  for  Matrix  Compensation  Benefits  to any
               attorney or subrogee shall be final.

          l.   If an appeal initiating arbitration is taken, the decision of the
               Arbitrator  or, if an  appeal  from the  report  and award of the
               Arbitrator is taken, the decision of the Court shall be final and
               binding  with  respect  to:  (a) The  gross  amount to be paid on
               account of a Claim for Matrix Compensation  Benefits unless there
               is a documented change in the physical condition of the Diet Drug
               Recipient  after  the  submission  of the claim  which  justifies
               consideration for a greater level of Matrix Compensation Benefits
               than that previously applied for or for payment at the same level
               as  previously  applied  for by  reason of a  different  physical
               condition  than that which was the subject of the prior Claim for
               Benefits by the Class  Member;  and (b) the  distribution  of any
               portion of the gross  amount to be paid for  Matrix  Compensation
               Benefits  to  any  attorney  or  subrogee  for  attorneys'  fees,
               reimbursement of litigation expenses, or subrogation claims.

          m.   Within  forty-five  (45)  days  after  the end of  each  calendar
               quarter or AIO Fiscal Quarter, whichever is applicable, after the
               AIO Start Date and prior to Final Judicial Approval, the Trustees
               and/or Claims  Administrator(s) shall pay the Matrix Compensation
               Benefit claims of all Class Members who:

               (1)  have  completed  Claims  for  Matrix  Compensation  Benefits
                    during  the  period  prior  to  the   commencement   of  the
                    above-referenced  calendar  quarter or AIO  Fiscal  Quarter,
                    whichever  is  applicable,  which  have not been  previously
                    paid; and

               (2)  have executed Individual Agreements pursuant to the AIO; and

               (3)  whose  rights to Matrix  Compensation  Benefits  have become
                    final during the  above-referenced  calendar  quarter or AIO
                    Fiscal Quarter,  whichever is applicable  under this Section
                    and are not then the  subject of an audit under the terms of
                    the Settlement Agreement.

               In distributing the amount due with respect to a claim for Matrix
               Compensation    Benefits,    the   Trustees   and/or   Settlement
               Administrator(s)  shall  pay  all  sums  due  to  the  individual
               attorney  for the Class  Member for  payment of counsel  fees and
               reimbursement  of  litigation  expenses,  and all sums due to any
               subrogee as  determined by the above  procedures.  The net amount
               remaining  after deducting such payments from the gross amount of
               the  Matrix  Compensation  Benefits  to which a Class  Member  is
               determined  to be  entitled,  shall be  distributed  to the Class
               Member.

          n.   Upon Final Judicial Approval,  the preceding paragraph will cease
               to be  effective  and the  following  schedule  will apply to the
               payment of all claims for Matrix Compensation Benefits. Within 45
               days after the close of each Fiscal Quarter,  the Trustees and/or
               Claims  Administrator(s)  shall  pay all  Claims  for the  Matrix
               Compensation Benefits of all Class Members who:

               (1)  have  completed  Claims  for  Matrix  Compensation  Benefits
                    during the period  prior to the  commencement  of the above-
                    referenced 45-day time period which have not been previously
                    paid; and

               (2)  whose  rights to Matrix  Compensation  Benefits  have become
                    final  during  the  above-referenced  Fiscal  Quarter  under
                    Section  VI.C.5,  and are not then the  subject  of an audit
                    under the terms of the Settlement Agreement.

               In distributing the amount due with respect to a claim for Matrix
               Compensation    Benefits,    the   Trustees   and/or   Settlement
               Administrator(s)  shall  pay  all  sums  due  to  the  individual
               attorney  for the Class  Member for  payment of counsel  fees and
               reimbursement  of  litigation  expenses,  and all sums due to any
               subrogee as  determined by the above  procedures.  The net amount
               remaining  after deducting such payments from the gross amount of
               the  Matrix  Compensation  Benefits  to which a Class  Member  is
               determined  to be  entitled,  shall be  distributed  to the Class
               Member.

          o.   The  payment  obligations  in  paragraphs  (m) and (n)  above are
               subject to the provisions of Section III.C.

     5.   Beginning on the Preliminary Approval Date, the Trustees and/or Claims
          Administrators  shall take the steps  reasonably  necessary to receive
          and  process  Claims  for  Benefits  according  to the  terms  of this
          Agreement,  but the time  periods  provided  in  Section  VI.C for the
          processing  of  Claims by Class  Members  and for any  actions  by the
          Trustees and/or Claims Administrator(s)  relating to such Claims shall
          not apply to any Claim until the later of September  30, 2000,  or the
          AIO Start  Date.  Further,  such time  periods  shall not apply to the
          Claims  of Class  Members  who have  submitted  BLUE  FORMS  until the
          earlier  of the Final  Judicial  Approval  Date or  February  1, 2001;
          provided,  however,  that the Trustees and/or Claims  Administrator(s)
          shall have the  authority  to process the Claims of Class  Members who
          have  submitted  BLUE FORMS  before such time if  warranted to achieve
          cost savings in the  processing of Claims.  At any time, the Court may
          extend  any time  period in  Section  VI.C for good  cause  shown upon
          application by the Parties, Trustees, Claims Administrator(s),  and/or
          Interim Claims Administrators, after notice to AHP and Class Counsel.

     D.   PROCEDURE FOR RECOGNITION OF CREDITS.

                    Credit"),  AHP  shall  supply  the  Trustees  and/or  Claims
                    Administrator(s)    with   the   following   documents   and
                    information:

                    (4)  a  copy  of  the  release(s)   executed  by  the  Class
                         Member(s) in favor of AHP;

                         Cardiothoracic Surgeon;

                    (6)  all  hospital  reports  of the  admitting  history  and
                         physical   examination  of  the  Diet  Drug  Recipient,

                         results which,  in whole or in part, form the basis for
                         the Request for Credit;

                    (8)  a   declaration   under   penalty  of  perjury  from  a
                         Board-Certified Cardiologist or Cardiothoracic Surgeon,
                         regardless of whether that  Cardiologist was originally
                         retained by AHP,  the  plaintiff  or  neither,  setting
                         forth an  opinion  to a  reasonable  degree of  medical
                         certainty  that (1) the  Diet  Drug  Recipient  has the
                         condition which would otherwise  qualify a Class Member
                         for  a  particular  Matrix  payment,  including,  where
                         applicable,  that the causation requirements applicable
                         to conditions  (b)(v) and (c) of Matrix-Level V, either
                         are or  are  not  present;  (2) to  the  best  of  such
                         physician's  knowledge after reasonable  inquiry,  such
                         condition  which  would  otherwise  qualify  the  Class
                         Member for a particular  Matrix payment was not present
                         prior to usage of Pondimin(R) and/or Redux(TM); and (3)
                         all the conditions  which determine  whether Matrix A-1
                         or B-1 are  applicable,  either are  present or are not
                         present;

                    (9)  a   declaration   under   penalty  of  perjury  from  a
                         Board-Certified  Cardiologist,  Cardiothoracic Surgeon,
                         Neurologist   or   Neurosurgeon   with  regard  to  the
                         functional outcome which the patient has had six months
                         after a stroke, if applicable;

                    (10) a   declaration   under   penalty  of  perjury  from  a
                         Board-Certified  Cardiologist,  Cardiothoracic Surgeon,
                         or   Pathologist   regarding   the   existence  of  the
                         pathological  criteria for Endocardial Fibrosis defined
                         in Section I.21 if applicable; and,

                    (11) any  other  documentation  which  the  Trustees  and/or
                         Claims  Administrators(s)  are otherwise  authorized to
                         request under this Settlement Agreement.

                    The records and  information  described in (1) through (11),
                    inclusive,  and/or  the  information  described  in  Section
                    VI.D.1.b. below are referred to as the "Credit Information."
                    Subject to the provisions of Section VI.D.1.b, a Request for
                    Credit shall not be considered  completed within the meaning
                    of Section VI.D.1.c.  and ready for determination  until the
                    Trustees  and/or Claims  Administrator(s)  have received all
                    Credit  Information  and a properly and fully  completed RED
                    FORM relating to such Request for Credit.

               b.   If AHP is unable to obtain the documentation described above
                    through the  exercise of  reasonable  efforts,  the Trustees
                    and/or  Claims  Administrator(s)  shall  have  the  right to
                    consider other  supporting  documentation  including but not
                    limited to  declaration(s)  of other Qualified  Physician(s)
                    under  penalty  of perjury  setting  forth  opinion(s)  to a
                    reasonable  degree of medical certainty to support the claim
                    that the  Class  Members'  condition  would  have  otherwise
                    entitled him or her to a Matrix  payment for which AHP would
                    be entitled  to a Credit,  subject to review by the Court as
                    set forth in Section VI.D.1.g.  If this evidence establishes
                    the Class  Member's  condition  to the  satisfaction  of the
                    Trustees  and/or  Claims  Administrator(s),   AHP  shall  be
                    entitled to receive the appropriate credit.

               c.   Within forty-five (45) days of receiving a completed Request
                    for   Credit   from  AHP,   the   Trustees   and/or   Claims
                    Administrator(s)  shall make a preliminary  determination as
                    to whether  AHP is  entitled  to a Credit,  and,  if so, the
                    amount of the  Credit to which  AHP is  entitled,  and shall
                    advise  AHP  and  Class   Counsel,   in  writing,   of  this
                    determination.

               d.   AHP and Class Counsel shall have  forty-five  (45) days from
                    the date of receiving  such a preliminary  determination  to
                    submit  additional  information  concerning  the question of
                    whether and to what extent a Credit should be given to AHP.

               e.   Within   sixty  (60)  days  of  receiving   any   additional
                    information  which is  submitted  pursuant to the  preceding
                    paragraph  or  within   ninety  (90)  days  of  receiving  a
                    completed  Request for Credit from AHP,  whichever is later,
                    the Trustees and/or Claims Administrators shall make a final
                    determination as to whether AHP is entitled to a Credit and,
                    if so,  the amount of Credit to which AHP is  entitled,  and
                    shall  advise  AHP and  Class  Counsel  in  writing  of this
                    determination.

               f.   Within  fifteen  (15)  days  of  receiving   notice  of  the
                    Trustees' determination, AHP may appeal the determination by
                    filing a notice of the appeal in the form appended hereto as
                    Exhibit  "24"  with the Trial  Court  and  serving a copy on
                    Class    Counsel,    and   the   Trustees    and/or   Claims
                    Administrator(s).

               g.   In the event of such an appeal,  the Court  shall  refer the
                    matter to  Arbitration by a single  Arbitrator  appointed by
                    the Court for that purpose.  The Arbitrator  shall determine
                    whether the Trustees have properly  applied the criteria set
                    forth  in  the  Settlement   Agreement  to  the  information
                    supplied  by AHP in  support of the  Request  for Credit and
                    shall  enter a report and award,  which  either  affirms the
                    decision of the  Trustees,  directs a different  Credit than
                    that which was  determined by the Trustees,  or directs that
                    no Credit shall be given to AHP. If the  Arbitrator  affirms
                    the  decision of the  Trustees or awards a lower Credit than
                    had been  awarded by the  Trustees and finds that the appeal
                    was taken or maintained by AHP in violation of the standards
                    set  forth  in   Fed.R.Civ.P.   11(b),   the  cost  of  this
                    Arbitration shall be borne by AHP.  Otherwise,  the costs of
                    such  Arbitration  shall be paid by the Trust. Any party may
                    appeal  from the report and award of the  Arbitrator  to the
                    Court.

               h.   If there is no appeal  initiating  an  Arbitration  process,
                    then the  decision of the  Trustees  with respect to a claim
                    for  a  Credit  shall  be  final.  If an  appeal  initiating
                    Arbitration is taken,  the decision of the Arbitrator or, if
                    an appeal  from the  report and award of the  Arbitrator  is
                    taken,  the  decision  of the  Court,  shall  be  final  and
                    binding.

          2.   Beginning on the  Preliminary  Approval Date, the Trustees and/or
               Claims  Administrators  shall take the steps reasonably necessary
               to receive and process  Requests  for  Credits  according  to the
               terms of this Agreement, but the time periods provided in Section
               VI.D for the  processing  of Requests  for Credits by AHP and for
               any   actions   by   AHP   and   the   Trustees   and/or   Claims
               Administrators(s) relating to such Requests for Credits shall not
               apply until the later of  September  30,  2000,  or the AIO Start
               Date.  At any  time,  the  Court may  extend  any time  period in
               Section  VI.D  for  good  cause  shown  upon  application  by the
               Parties, Trustees, Claims Administrator(s), and/or Interim Claims
               Administrators, after notice to AHP and Class Counsel.

     E.   AUDITS OF CLAIMS BY TRUSTEES AND/OR CLAIMS ADMINISTRATOR(S)

          1.   After the AIO  Start  Date,  on a  quarterly  basis the  Trustees
               and/or Claims  Administrator(s)  shall audit five percent (5%) of
               the total  Claims  for  Matrix  Compensation  Benefits  completed
               (within  the  meaning of Section  VI.C.2 and  Section  VI.C.4) by
               Class Members during the prior quarter,  and ten percent (10%) of
               the total  Requests  for  Credits  made by AHP  during  the prior
               quarter. Claims for Matrix Compensation Benefits and Requests for
               Credits  shall be selected for audit  pursuant to this Section of
               the Settlement Agreement as follows:

               a.   The Trustees and/or Claims Administrator(s) shall retain one
                    or more Board-Certified Cardiologists, who have successfully
                    completed  level  three  training in  echocardiography,  for
                    purposes  of  reviewing   claims  for  Matrix   Compensation
                    Benefits made by Class Members and Requests for Credits made
                    by  AHP  (hereinafter  "the  Reviewing  Cardiologist").  The
                    Reviewing  Cardiologist  shall review a total of ten percent
                    (10%) of the total Claims for Matrix  Compensation  Benefits
                    completed  (within the meaning of Section VI.C.2 and Section
                    VI.C.4) by Class Members during the prior  quarter,  and ten
                    percent (10%) of the total  Requests for Credits made by AHP
                    during the prior  quarter.  This review  shall  consist of a
                    comparison   between   the  Medical   Information   and  the
                    information  on the GREEN FORM  submitted  by a Class Member
                    (in the case of a Claim for Matrix Compensation Benefits) or
                    a  comparison   between  the  Credit   Information  and  the
                    information on the RED FORM submitted by AHP (in the case of
                    a Request for Credit) for  purposes of  determining  whether
                    there is a  material  discrepancy  between  the  Medical  or
                    Credit  Information  submitted in connection with a Claim or
                    Request  for  Credit and the  information  on the GREEN FORM
                    submitted  by a Class  Member or the RED FORM  submitted  by
                    AHP. In the event that the Reviewing Cardiologist determines
                    that there is such a material discrepancy, then the Claim or
                    Request for Credit shall be referred  for audit  pursuant to
                    this section of the Settlement Agreement.

               b.   In addition to the procedure  provided in Section  VI.E.1.a,
                    the Trustees  and/or  Claims  Administrator(s)  shall select
                    additional Claims for Matrix Compensation  Benefits by Class
                    Members  and  Requests  for  Credits by AHP during the prior
                    quarter for audit pursuant to an audit plan which shall take
                    into account, among other things:

                    (1)  The fact that certain Class Members are  represented by
                         attorneys who represent what the Trustees and/or Claims
                         Administrator(s)  determine  to  be a  disproportionate
                         number of Class Members;

                    (2)  The fact that certain  Class Members or AHP rely on the
                         certifications    of   doctors   who   have    provided
                         certifications  for what  the  Trustees  and/or  Claims
                         Administrator(s)  determine  to  be a  disproportionate
                         number of Class Members or Requests for Credits; and

                    (3)  The need to incorporate  random sampling into the Audit
                         Plan;

                    provided  however,  that under  this  Section  VI.E.1.b  and
                    Section VI.E.1.a  combined the Trustees shall not audit more
                    than  five  percent  (5%) of the  total  Claims  for  Matrix
                    Compensation  Benefits completed by Class Members during the
                    prior quarter and ten percent (10%) of the total Request for
                    Credits made by AHP during the prior quarter, subject to the
                    provisions of Section VI.F.

          2.   A Claim  may not be paid and a Credit  may not be  allowed  while
               that Claim or Credit is  subject of an audit or a request  for an
               audit.  If a Claim of a Diet  Drug  Recipient  or  Representative
               Claimant  is  subject to audit or a request  for audit,  then the
               Claims of all  Derivative  Claimant(s)  based on that Claim shall
               also be subject to the audit or audit  request,  but shall not be
               considered  as part of the  percentage of Claims to be audited by
               the Trustees and/or Claims Administrator(s) in that quarter.

          3.   With respect to Claims which are selected for audit, the Trustees
               and/or  Claims   Administrator(s)  may  require  that  the  Class
               Member(s)  provide  them  with  the  following  information  as a
               condition to consideration of the Claim:

               a.   Identification   of  all   general   practitioners,   family
                    physicians,   primary   care   providers,    internists   or
                    sub-specialists   in   internal   medicine,    surgeons   or
                    sub-specialists    in   surgery,    and   obstetricians   or
                    gynecologists  who, at any time  during the  10-year  period
                    prior to the filing of the Claim subject to audit,  rendered
                    any medical  care to and/or were  consulted by the Diet Drug
                    Recipient  whose Claim forms the basis of the Claim  subject
                    to audit;

               b.   Fully completed and executed authorizations which will allow
                    the Trustees and/or Claims Administrator(s) to obtain copies
                    of the Class Member's medical records; and

               c.   Such other  relevant  documents  or  information  within the
                    Class  Member's  custody,  possession,  or  control  as  may
                    reasonably  be  requested  by  the  Trustees  and/or  Claims
                    Administrator(s).

                    If the Class Member unreasonably fails or refuses to provide
                    any material  documents or information  after being afforded
                    an adequate  opportunity  to do so, the Class Member's Claim
                    shall be denied.

          4.   With respect to requests for Credit which are selected for audit,
               the Trustees and/or Claims  Administrator(s) may require that AHP
               provide  them with the  following  information  as a condition to
               consideration of a Request for Credit:

               a.   All  medical  records  relating  to the Diet Drug  Recipient
                    whose  condition  is the  subject of the Request for Credit,
                    which are in the custody,  possession, or control of AHP and
                    its counsel;

               b.   All  depositions,  interrogatories,  fact  sheets,  and like
                    documents relating to the condition and circumstances of the
                    Diet Drug  Recipient  whose  condition is the subject of the
                    Request for Credit, which are in the custody,  possession or
                    control of AHP and its counsel;

               c.   Such other relevant documents or information within AHP's or
                    its  counsel's   custody,   possession  or  control  as  may
                    reasonably  be  requested  by  the  Trustees  and/or  Claims
                    Administrator(s).

          5.   If AHP  unreasonably  fails or refuses to  provide  any  material
               documents or  information  after being afforded an opportunity to
               do so, its Request for Credit shall be denied.

          6.   In  conducting  an audit of those  Claims and Requests for Credit
               selected for audit,  the Trustees and/or Claims  Administrator(s)
               shall   follow   the   following   procedure:   All   Accelerated
               Implementation   Option   acceptance   form(s)   ("PINK   FORM"),
               registration  form(s)  ("BLUE  FORM"),  videotapes  or  disks  of
               Echocardiograms, medical reports, and other information submitted
               by AHP in support of a Request for Credit or by a Class Member in
               support  of a  Claim,  together  with  a copy  of the  claimant's
               medical records, and Echocardiogram  videotapes or disks obtained
               by the Trustees/Claims  Administrator(s)  shall be forwarded to a
               highly-  qualified,  independent,   Board-Certified  Cardiologist
               (hereinafter referred to as the "Auditing Cardiologist") selected
               by  the   Trustees/Claims   Administrator(s).   After  thoroughly
               reviewing these materials, the Auditing Cardiologist shall make a
               determination as to whether or not there was a reasonable medical
               basis for the representations made by any physician in support of
               the Claim or Request for Credit.

          7.   If the Auditing  Cardiologist  makes the determination that there
               was a  reasonable  medical  basis to support  the Class  Member's
               Claim or AHP's Request for Credit and if there is no  substantial
               evidence  that  the  Class  Member  or AHP  intentionally  made a
               material  misrepresentation of fact in connection with a Claim or
               a Request for Credit,  then the Claim or Credit shall be allowed.
               If,  on the  other  hand,  the  Auditing  Cardiologist  makes the
               determination  that  there  was no  reasonable  medical  basis to
               support any of the material representations made by any physician
               in  support  of the Class  Member's  Claim or AHP's  Request  for
               Credit,  or  if  the  Trustees  and/or  Claims   Administrator(s)
               determine  that the  Class  Member  or AHP  intentionally  made a
               material  misrepresentation  of fact, the Trustees  and/or Claims
               Administrator(s)  shall not pay the Claim or allow the Credit and
               shall apply to the Court for an order to show cause why the Claim
               should be paid or the Credit should be allowed,  and for an order
               to show  cause as to why other  Claims or Credits  involving  the
               same attorney and/or physician should not be subject to an audit.

          8.   If the Court  determines  that  there was no  reasonable  medical
               basis to support a material representation made by a physician in
               support of a Claim or Request for Credit or that the Class Member
               or AHP intentionally made a material misrepresentation of fact in
               connection with Claim or Request for Credit, after the entry of a
               show  cause  order  and  a  hearing  pursuant  to  the  preceding
               paragraph, the Court may grant such relief as may be appropriate,
               including any of the following:

               a.   an order disallowing the Claim or Credit;

               b.   an order  directing an  additional  audit of other Claims or
                    credits  involving the same attorneys and/or  physicians who
                    were  involved in the Claim or Request for Credit  which was
                    the subject of the show cause order;

               c.   an order  directing such other  additional  audits as may be
                    appropriate in light of the Court's findings;

               d.   an order  imposing  penalties  including  the payment of the
                    Trustees' and/or Claims Administrators' costs and attorneys'
                    fees to the extent permitted by law; and/or

               e.   an order  making a  referral  of the  matter  to the  United
                    States   Attorney  or  other   appropriate  law  enforcement
                    officials  for  possible  criminal  prosecution  if there is
                    probable  cause to  believe  that the  Claim  was  submitted
                    fraudulently.

               For good cause shown, including without limitation the results of
               audits  conducted  on any one or more  Claims,  groups of Claims,
               and/or  requests  for Credits made by AHP, the Court at any time,
               upon its own motion  after  notice to AHP and Class  Counsel,  or
               upon motion by any party and after such notice and hearing as the
               Court  may  direct,   may  order  the  Trustees   and/or   Claims
               Administrators  to perform such  additional  audits  and/or adopt
               such  additional  claims  administration  procedures as the Court
               deems appropriate.

     F.   AHP-INITIATED AUDITS OF CLAIMS

          1.   AHP may  have  access  to all  Claim  Forms  for Fund A or Fund B
               benefits submitted to the Trustees and/or Claims Administrator(s)
               and   to  all   medical   records,   videotapes   or   disks   of
               Echocardiograms,  forms  submitted  by  Class  Members,  pharmacy
               records and all other  documents  submitted  by Class  Members in
               support of their Claims, upon reasonable request to the Trustees.
               Access to such documents shall be provided to AHP by the Trustees
               and/or Claim Administrator(s) no later than five (5) days after a
               Claim is  completed  (within  the  meaning of Section  VI.C.2 and
               Section VI.C.4).

          2.   AHP  shall   have  no  right  to   participate   in  the   claims
               determination  process for a particular Class Member as described
               in Section VI.C above; provided, however, that AHP shall have the
               right to  submit  particular  Claims  or  groups of Claims to the
               Trustees and/or Claims  Administrator(s) for audit, up to a total
               per  quarter of 10% of the total  Claims for Matrix  Compensation
               Benefits  and  10% of  the  total  claims  for  Fund  A  Benefits
               completed by Class Members during the prior  quarter.  Along with
               such  submissions,  AHP shall identify to or provide the Trustees
               and/or Claims  Administrator(s)  information or  documentation in
               its possession that it believes establishes either that there was
               no reasonable  medical basis to support the Class  Member's Claim
               or that the Class  Member  made a material  misrepresentation  of
               fact in connection with a Claim.

          3.   The  Trustees  and/or  Claims  Administrator(s)  shall  audit all
               Claims  properly  submitted by AHP for audit under Section VI.F.2
               above in a particular  quarter.  Such Claims shall be in addition
               to and  different  from the 5% of Claims  audited by the Trustees
               and/or  Claims  Administrators  per  quarter  pursuant to Section
               VI.E.1.  Should  any of the  Claims  submitted  for  audit by AHP
               include   those   selected   by  the   Trustees   and/or   Claims
               Administrators  for audit in the same quarter,  then the Trustees
               and/or Claims  Administrators shall select other Claims for audit
               to ensure  their audit of 5% of Claims per quarter as required by
               Section  VI.E.1 in  addition to the Claims  submitted  by AHP for
               audit.

          4.   If Class  Counsel or AHP has a good faith belief that an Auditing
               Cardiologist  employed  by the  Trustees  has  failed to  perform
               his/her duties in accordance  with accepted  standards of medical
               practice,  they may apply to the Court  for  appropriate  relief,
               including an order disqualifying the Auditing  Cardiololgist from
               any further  participation in any audits and requiring a re-audit
               of those  Claims or  Requests  for Credit for which the  Auditing
               Cardiologist made a determination.

          5.   In  connection  with any audit  initiated  by AHP  under  Section
               VI.F.2,  AHP shall have the right to obtain,  at its expense,  an
               independent Transthoracic Echocardiogram of a Diet Drug Recipient
               who has made a claim for  Matrix  Benefits  under  the  following
               circumstances:

               a.   where AHP presents  evidence to the Trustees  and/or  Claims
                    Administrator(s) that the center or physician from which the
                    Echocardiogram was obtained has a disproportionate number of
                    FDA Positive or Matrix-Level Claims; or

               b.   where AHP  submits a  certification  from a  Board-Certified
                    Cardiologist under penalty of perjury that the report of the
                    Echocardiogram   and/or  the   videotape   or  disk  deviate
                    materially from accepted standards of practice in the fields
                    of Cardiology or Echocardiography; or

               c.   where   AHP   submits   to  the   Trustees   and/or   Claims
                    Administrator(s)  evidence  that  the  Class  Member  or any
                    physician  making  representations  in  support  of a  Class
                    Member's Claim made material misrepresentations of fact; or

               d.   where AHP  submits a  certification  from a  Board-Certified
                    Cardiologist  under penalty of perjury that the videotape or
                    disk of the  Echocardiogram  cannot properly be read for any
                    reason,  including,  but not limited to,  poor  quality,  or
                    improper setting.

          6.   Independent  AHP  Echocardiograms  conducted  pursuant to Section
               VI.F.5 above, shall be subject to the following conditions:

               a.   the  affected  Class Member will be afforded at least ninety
                    (90) days within which to schedule the  Echocardiogram  at a
                    time convenient to the Class Member;

               b.   the   Echocardiogram   shall   take   place  not  more  than
                    twenty-five  (25)  miles  from the Class  Member's  place of
                    residence  unless AHP  provides  transportation,  but, in no
                    event, more than 100 miles;

               c.   AHP shall pay for the Echocardiogram;

               d.   Echocardiogram shall be conducted pursuant to the procedures
                    set forth in Section I.54.

               e.   a report of the  Echocardiogram  together with a copy of the
                    videotape and/or disk of the Echocardiogram results shall be
                    submitted to the Trustees and/or Claims Administrator(s) and
                    to the  Diet  Drug  Recipient  who  was the  subject  of the
                    Echocardiogram.

                    If  the  results  of  the  report  of  the  Independent  AHP
                    Echocardiogram  obtained by AHP  pursuant to this  paragraph
                    differ  materially  and  significantly  from the  results or
                    report of the  Echocardiogram  submitted by the Class Member
                    in support of the Class  Member's  Claim for Benefits,  then
                    the Trustees  and/or  Claims  Administrator(s)  may in their
                    discretion take the results into consideration in connection
                    with their audit.




VII.     AHP RIGHTS AND BENEFITS

     A.   CREDITS

          1.   If a Class  Member  timely and  properly  exercises an Initial or
               Back-End  Opt-Out  right  pursuant  to Section  IV.D.2 or Section
               IV.D.4  hereof,  asserts a claim and obtains any payment from AHP
               as a result of such claim (whether  pursuant to a pre-Judgment or
               post-Judgment  settlement of such claim or pursuant to a judgment
               on such  claim),  AHP shall  receive  Credits  against its Fund B
               obligations  to the  extent  set  forth  in  this  Section  VII.A
               ("Credits").

          2.   With respect to an Initial Opt-Out,  if (a) a Diet Drug Recipient
               (or his or her Representative Claimants) timely and properly opts
               out of this  Settlement as an Initial  Opt-Out during the Initial
               Opt-Out  Period and the Diet Drug  Recipient  has a  Matrix-Level
               Condition at the time of such Initial  Opt-Out or payment by AHP,
               and/or (b) a Derivative  Claimant of such Diet Drug  Recipient is
               deemed to have opted out of this  Settlement  pursuant to Section
               IV.D.2,  then AHP shall receive a Full Credit with respect to any
               amounts  paid by AHP to such Diet Drug  Recipient  (or his or her
               Representative  Claimants)  and/or  to  the  Derivative  Claimant
               ("Initial Opt-Out Credits"),  regardless of whether such payments
               were made pursuant to a Judgment or pre-Judgment or post-Judgment
               settlement, subject to the following:

               a.   Initial   Opt-Out  Credits  shall  not  exceed  the  sum  of
                    $300,000,000, in the aggregate.

               b.   Initial  Opt-Out  Credits  shall be  applied  to reduce  the
                    Adjusted Maximum  Available Fund B Amount upon the later of:
                    (i) the date  that is five  calendar  years  after the Final
                    Judicial  Approval  Date;  or (ii)  the  date on  which  the
                    determination  of the Initial  Opt-Out  Credit becomes final
                    under Section VI.D.1.

               c.   Even though the  application of Initial  Opt-Out  Credits to
                    reduce  the  Adjusted  Maximum  Available  Fund B Amount  is
                    deferred pursuant to Section VII.A.2.b above, there shall be
                    no  accretions  on  Initial  Opt-Out  Credits  (or any other
                    Credits due AHP) under this Agreement.

          3.   With respect to a Back-End Opt-Out,  if (a) a Diet Drug Recipient
               (or his or her  Representative  Claimants)  timely  and  properly
               exercises a Back-End  Opt-Out under this Agreement,  and the Diet
               Drug  Recipient has a  Matrix-Level  Condition at the time of the
               exercise  of  such  Back-End  Opt-Out,  and/or  (b) a  Derivative
               Claimant of such Diet Drug  Recipient is deemed to have opted out
               of this Agreement  pursuant to Section IV.D.4 or otherwise,  then
               AHP shall receive a Full Credit ("Back-End  Opt-Out Credit") with
               respect to any  amounts  paid by AHP to such Diet Drug  Recipient
               (or his or her Representative Claimants) and/or to the Derivative
               Claimant,  regardless of whether such payments were made pursuant
               to  a  Judgment  or  pre-Judgment  or  post-Judgment  settlement.
               Back-End  Opt-Out Credits shall be applied to reduce the Adjusted
               Maximum  Available  Fund B Amount  as of the  date on  which  the
               determination  of the Back-End Opt-Out Credit becomes final under
               Section VI.D.1.

          4.   For purposes of this Section VII.A:

               "Judgment" shall mean any decision by a court of law or any other
               authorized tribunal.

               "Full Credit" shall mean a Credit in the amount of the lesser of:

               (a)  the amount of payment to the Diet Drug  Recipient (or his or
                    her Representative Claimant) and/or Derivative Claimant; or

               (b)  the Matrix  payment for which such Diet Drug  Recipient  (or
                    his  or  her  representative   Claimant)  and/or  Derivative
                    Claimant  would have  qualified  (as  determined at the time
                    such  individual  opted out of this Agreement or at the time
                    of payment of such amount, whichever is higher), less Common
                    Benefit  Attorney's  fees  (such  fees  not to  exceed  nine
                    percent (9%) of such Matrix payment).

               "Back-End Opt-Out" includes any Class Member who has exercised or
               purported to exercise  any opt-out  right under the terms of this
               Agreement  where:  (i) the opt-out right was exercised  after the
               end of the Initial  Opt-Out  Period;  (ii) the relevant Diet Drug
               Recipient was first diagnosed with a Matrix-Level Condition after
               September 30, 1999, and before the Matrix  Payment  Cut-Off Date;
               and (iii) the Class Member meets the  eligibility  criteria for a
               Back-End  Opt-Out  under  Section  IV.D.4.a  of  this  Agreement,
               regardless of the manner in which the Class Member  characterized
               the opt-out.

          5.   In order to qualify for any of these  Credits,  AHP must  provide
               the Trustees and/or Claims  Administrator(s) with the appropriate
               Credit Information described in Section VI.D.1.a above.

     B.   EFFECT ON CLAIMS

          1.   Effective  upon Final Judicial  Approval,  every Settled Claim of
               each Class Member  against AHP or any other  Released Party shall
               be conclusively compromised,  settled and released, and each such
               Class  Member  shall be  barred  from  initiating,  asserting  or
               prosecuting  any Settled Claim against AHP or any other  Released
               Party,   except  to  the  extent  permitted  by  this  Settlement
               Agreement  for any  Class  Member  who has  timely  and  properly
               exercised any applicable opt-out right.

          2.   To confirm the  provisions set forth in Section  VII.B.1,  above,
               within  five  days  after  Final  Judicial  Approval,  the  Class
               Representatives,  individually  and on behalf  of the  Settlement
               Class and all of the  Subclasses,  shall  deliver  to AHP a fully
               executed  Release and Covenant Not to Sue in the form attached as
               Exhibit "27" .

          3.   Each Class  Member  shall be  required  to execute an  individual
               Release and Covenant Not to Sue as part of the forms  required to
               be submitted by Class Members in order to seek to  participate in
               the benefits of the Settlement.  Such  individual  releases shall
               become  ineffective,   null  and  void  in  the  event  that  the
               Settlement  fails to obtain  Final  Judicial  Approval  or in the
               event that AHP terminates  this  Agreement for any reason,  other
               than as to persons entering into AIO Individual Agreements.  Such
               individual  releases shall  furthermore be ineffective,  null and
               void as to all Settled  Claims  except those set forth in I.53(e)
               and (g) above,  with  respect to any Class  Member who timely and
               properly  exercises any applicable  opt-out right granted by this
               Agreement subsequent to the execution of the releases.

          4.   For purposes of any statute of  limitations  or similar time bar,
               the AHP  Released  Parties  shall not assert that a Class  Member
               actually  had PPH  unless  and until the  condition  of the Class
               Member meets the definition of PPH set forth in Section I.46.

          5.   In the event that a Class Member  initiates a claim based on PPH,
               the AHP  Released  Parties  shall not  assert a defense  based on
               "splitting" of claims,  causes of action and/or parties by virtue
               of the fact that the Class Member is included in the  Settlement,
               but the claim based on PPH is not a Settled Claim.

          6.   The forms of release  necessary to effectuate this Settlement and
               the Accelerated  Implementation Option set forth in Section V are
               set forth in the PINK FORM (for Class Members  accepting the AIO)
               and the BLUE FORM (for all other Class Members)  appended  hereto
               as Exhibits "9" and "21" respectively.

          7.   The amended  complaint in Sheila  Brown,  et al. v. American Home
               Products  Corporation,  Civil Action No. 99-20593 (E.D. Pa.), and
               all  Settled  Claims  which  were or could  have  been  asserted,
               including  claims  for  punitive   damages,   on  behalf  of  the
               Settlement  Class or any subclass against AHP and/or any Released
               Parties  shall be  dismissed  with  prejudice  upon  Trial  Court
               Approval.  Such  dismissal  will be vacated in the event that the
               Settlement does not receive Final Judicial Approval.

          8.   After Date 2, the  following  persons shall have no further right
               to any benefits  under the  Settlement and shall have no right to
               pursue any  Settled  Claims  against AHP or any  Released  Party,
               except to the extent such persons  timely and properly  exercise,
               or  have  exercised,  an  Initial,   Intermediate,   Back-End  or
               Financial Insecurity Opt-Out:

               a.   with  respect  to  all  Settled  Claims  against  AHP or any
                    Released   Party  other  than  those  based  on  Endocardial
                    Fibrosis, any Class Member asserting a claim based on a Diet
                    Drug  Recipient  who:  (a)  has  not  been  diagnosed  by  a
                    Qualified  Physician  as FDA  Positive  nor as  having  Mild
                    Mitral Regurgitation by an Echocardiogram  performed between
                    the  commencement  of  Diet  Drug  use  and  the  end of the
                    Screening  Period,  or (b) has been diagnosed by a Qualified
                    Physician   as  FDA   Positive  or  as  having  Mild  Mitral
                    Regurgitation  by an  Echocardiogram  performed  between the
                    commencement  of Diet Drug use and the end of the  Screening
                    Period,  but the Class  Member  has not  registered  or been
                    deemed to have registered for settlement benefits by Date 2.

               b.   with respect to Settled  Claims  against AHP or any Released
                    Party  based  on  Endocardial  Fibrosis,  any  Class  Member
                    asserting a claim based on a Diet Drug  Recipient  who:  (a)
                    has not been  diagnosed  by a Qualified  Physician as having
                    Endocardial  Fibrosis by September 30, 2005, or (b) has been
                    diagnosed  by a Qualified  Physician  as having  Endocardial
                    Fibrosis by September 30, 2005, but the Class Member has not
                    registered or been deemed to have  registered for settlement
                    benefits by January 31, 2006.



     C.   PROTECTION OF AHP FROM CLAIMS BY NON-SETTLING DEFENDANTS

          1.   It is the intent of this Settlement  Agreement that no Settlement
               Class Member shall recover, directly or indirectly,  any sums for
               Settled  Claims from AHP or any  Released  Party other than those
               received under the  Settlement  Agreement and that AHP shall make
               no payments to any third party defined  herein as a  Non-Settling
               Defendant for any amounts  arising out of a Settled Claim brought
               by a Class Member against such Non-Settling Defendant,  except to
               the extent that Class  Members  timely and  properly  exercise an
               Initial,  Intermediate, or Back-End Opt-Out right provided by the
               Settlement Agreement. It is the further intent of this Settlement
               Agreement  that  Settlement  Class  Members  agree to reduce  any
               judgments   against   Non-Settling   Defendants   to  the  extent
               necessary,  under applicable law, to relieve AHP and the Released
               Parties  of  liability  for   contribution   or   non-contractual
               indemnity to any Non-Settling Defendant. In particular:

               a.   The Parties shall seek an order from the Court,  which shall
                    be a condition to AHP's  obligations under this Agreement as
                    set forth in Section  VIII.D  hereof,  enjoining and barring
                    all  Non-Settling  Defendants from commencing or prosecuting
                    any  claim  against  AHP or any  other  Released  Party  for
                    contribution and/or non-contractual  indemnity,  arising out
                    of a claim against such Non-Settling  Defendant on behalf of
                    any Class Member asserting  Settled Claims in any present or
                    future  litigation,  other  than any  Class  Member  who has
                    timely and properly  exercised an Initial,  Intermediate  or
                    Back-End  Opt-Out  right  provided  by  this  Agreement  and
                    subject to the provisions of Section VII.C.2 below.

               b.   Nothing in this  Agreement is intended to  adversely  affect
                    any  Non-Settling  Defendant's  right, if any, to set-off or
                    judgment   reduction  under  any  state  contribution  among
                    tortfeasors  act  or  other  applicable  law.   Non-Settling
                    Defendants  will be  entitled,  at a  minimum,  to  whatever
                    set-off or judgment  reduction is afforded them by operation
                    of  applicable  law.  Settlement  Class  Members  who do not
                    timely  and  properly  exercise  Initial,   Intermediate  or
                    Back-End  Opt-Out rights agree that all defendants are joint
                    tortfeasors in cases in which  Settlement Class Members have
                    joined  Non-Settling  Defendants,  AHP,  and/or the Released
                    Parties  or in any other  case in which a  Settled  Claim is
                    asserted.

               c.   The Parties  recognize  that,  under the law of some states,
                    claims for contribution or non-contractual indemnity against
                    a  settling   defendant  survive  a  Settlement  unless  the
                    Settlement  provides  set-off or judgment  reduction  rights
                    that go beyond those that would otherwise exist by operation
                    of applicable  law. In those cases,  the Parties intend that
                    Non-Settling  Defendants shall be entitled to the additional
                    set-off or judgment reduction necessary under applicable law
                    to extinguish  Non-Settling  Defendants' claims, if any, for
                    contribution or  non-contractual  indemnity  against AHP and
                    the  Released  Parties  arising  from  Settled  Claims only.
                    Settlement  Class Members,  however,  reserve their right to
                    contend that, due to the nature of the theories of liability
                    alleged or  presented  against the  Non-Settling  Defendants
                    (i.e.,  conspiracy  or  concert  of  action),   Non-Settling
                    Defendants have no right to contribution or  non-contractual
                    indemnity  from AHP or the  Released  Parties as a matter of
                    law even though they are joint tortfeasors.

               d.   In the event  that any claim that a  Non-Settling  Defendant
                    would have for  contribution  or  non-contractual  indemnity
                    against AHP or the  Released  Parties in the absence of this
                    Settlement  Agreement  with respect to a Settled Claim would
                    not be extinguished  under  applicable law by the set-off or
                    judgment reduction to which the Non-Settling Defendant would
                    be entitled by operation of law, any Settlement Class Member
                    who recovers a judgment against any  Non-Settling  Defendant
                    with  respect  to a Settled  Claim for which AHP  and/or any
                    Released  Party would be liable by a claim for  contribution
                    or non-contractual  indemnity but for the provisions of this
                    Settlement Agreement,  shall reduce his judgment against the
                    Non-Settling Defendant by the amount,  percentage,  or share
                    of such judgment necessary, under applicable law, to relieve
                    AHP and the Released  Parties of liability for  contribution
                    or  non-contractual  indemnity.  By way of example,  under a
                    statute   modeled  on  the  1939   version  of  the  Uniform
                    Contribution Among Tortfeasors Act, Settlement Class Members
                    would reduce their judgments against Non-Settling Defendants
                    in the situation  described in this Section to the extent of
                    the pro rata shares (as determined  under applicable law) of
                    AHP and any  relevant  Released  Party.  In the absence of a
                    statute,   Settlement   Class  Members  would  reduce  their
                    judgments against  Non-Settling  Defendants in the situation
                    described  in this  Section by the  amount,  percentage,  or
                    share of such judgment that would  lawfully be  attributable
                    to AHP and/or  the  Released  Party or  Parties  but for the
                    provisions of this Settlement Agreement.

               e.   To  avoid  inconvenience  and  expense  to  AHP,  the  other
                    Released Parties,  and the Settlement Class Members,  and to
                    eliminate  the objection  that certain  states' law requires
                    that AHP and the  Released  Parties  remain as  parties in a
                    lawsuit  to  facilitate  the  adjudication  of  Non-Settling
                    Defendants'   set-off  or  judgment  reduction  rights  with
                    respect to a Settled Claim, the releases provided under this
                    Settlement  Agreement  shall  incorporate,   to  the  extent
                    required by applicable law, what is known in Pennsylvania as
                    a "Griffin  release"  and/or what is known in Wisconsin  and
                    elsewhere  as a  "Pierringer  release."  By this  provision,
                    Settlement  Class Members and Class Counsel acting on behalf
                    of  Settlement  Class  Members  agree  that  the  lack  of a
                    judicial  determination  that the  settling  defendant  is a
                    joint tortfeasor does not preclude  Non-Settling  Defendants
                    from  obtaining  set-off or judgment  reduction  rights they
                    would otherwise have under  applicable law in the absence of
                    this Agreement.  See Griffin v. United States, 500 F.2d 1059
                    (3d Cir.  1974);  Pierringer v. Hoger,  124 N.W.2d 106 (Wis.
                    1963). By this provision, Settlement Class Members and Class
                    Counsel acting on behalf of Settlement Class Members further
                    agree to waive any  rights  that  they  might  have  against
                    Non-Settling Defendants, the assertion of which would, under
                    applicable  law,  allow  Non-Settling  Defendants  to add or
                    retain AHP  and/or the  Released  Parties as  defendants  in
                    actions   brought  by  Settlement   Class  Members   against
                    Non-Settling  Defendants  with respect to Settled Claims for
                    the purpose of adjudicating Non-Settling Defendants' rights,
                    if any, to set-off or judgment reduction.  This provision is
                    intended to obviate the  necessity and expense of having AHP
                    and the Released  Parties  added or remain as parties on the
                    record and obliged to  participate in a trial merely for the
                    purpose of determining  if in fact they were  tortfeasors so
                    as to  entitle  other  tortfeasors  to a  reduction  of  any
                    verdict.  This provision,  however, in no way constitutes an
                    admission of liability by AHP and the Released Parties or an
                    admission by Settlement  Class Members that any Non-Settling
                    Defendant  is entitled to  contribution  or  non-contractual
                    indemnity from AHP or a Released Party.

               f.   The Parties intend that this Settlement  Agreement result in
                    the termination or bar of all claims for contribution and/or
                    non-contractual  indemnity  against  AHP  and  the  Released
                    Parties with respect to Settled  Claims.  To the extent that
                    the   Parties'   intent  is  not  fully   realized,   and  a
                    Non-Settling  Defendant  obtains a judgment for contribution
                    or  non-contractual  indemnity against AHP and/or a Released
                    Party  with  respect  to Settled  Claims,  Settlement  Class
                    Members agree to reduce their judgments against Non-Settling
                    Defendants  by the  amount,  percentage,  or  share  of such
                    judgment   necessary   to  satisfy  any  such   judgment  or
                    non-contractual  indemnity for the benefit of AHP and/or the
                    Released Party.  If, despite the provisions of this section,
                    AHP or any  Released  Party  incurs any  judgments  due to a
                    claim for  contribution or  non-contractual  indemnification
                    arising out of a claim brought by a Settlement  Class Member
                    against a  Non-Settling  Defendant,  such  Settlement  Class
                    Member shall indemnify AHP and the Released Parties for such
                    amount,  provided  that AHP and the Released  Parties  shall
                    have made all  reasonable  efforts  to avoid  liability  for
                    contribution    and/or    non-contractual    indemnity    to
                    Non-Settling  Defendants under the Settlement Agreement.  In
                    this regard,  AHP shall have the right to recover  indemnity
                    obligations  from any unpaid Matrix payments that may be due
                    to the Class Member.

               g.   If,  despite  the  provisions  of this  section,  AHP or any
                    Released  Party  makes a payment  of any  judgment  due to a
                    claim  for  contribution  and/or  non-contractual  indemnity
                    arising out of a claim brought by a Settlement  Class Member
                    against a  Non-Settling  Defendant with respect to a Settled
                    Claim,  such Settlement Class Member shall indemnify AHP and
                    the  Released  Parties for such  amount,  and AHP shall make
                    reasonable  efforts to reduce such indemnity  obligations to
                    judgment  in  the   underlying   litigation   involving  the
                    Non-Settling  Defendant. To the extent that, for any reason,
                    a Settlement Class Member has failed to satisfy an indemnity
                    obligation   arising  under  this  paragraph  or  the  prior
                    paragraph  (either  directly or through recovery of payments
                    for Matrix-Level  Conditions otherwise due the Class Member)
                    within 90 days after AHP makes any such payment, AHP may, at
                    any time thereafter, assign its indemnity rights against the
                    Class  Member to the  Trustees  and,  in such  event,  shall
                    receive  a  credit  against  its Fund B  obligations  in the
                    amount  of  the  unsatisfied  portion  of the  indemnity  (a
                    "Cross-Claim Credit").  Cross-Claim Credits shall be applied
                    to reduce the Adjusted Maximum Available Fund B Amount as of
                    the  date on  which  the  determination  of the  Cross-Claim
                    Credit becomes final.

          2.   To protect further the Non-Settling  Defendants'  interests,  the
               Parties  have  agreed that the bar order  shall  incorporate  the
               following provisions:

               a.   If,   despite  the  provisions  of  Section   VII.C.1,   (i)
                    applicable  law  precludes  a  Non-Settling  Defendant  from
                    obtaining  a  set-off  or  judgment  reduction  to  which  a
                    Non-Settling  Defendant  would  otherwise be entitled  under
                    applicable law in an individual case brought by a Settlement
                    Class Member with respect to a Settled Claim without  naming
                    AHP or a Released Party as a party in the lawsuit,  and (ii)
                    the  Non-Settling  Defendant and the Settlement Class Member
                    cannot reach agreement on this issue sufficient to eliminate
                    the Non-Settling  Defendant's  alleged need to name AHP or a
                    Released Party in the lawsuit,  the  Non-Settling  Defendant
                    may apply to the Court for relief from the bar order.

               b.   The Non-Settling  Defendant's application to the Court shall
                    set forth with  specificity (i) the facts and law that would
                    give rise to a claim for contribution and/or non-contractual
                    indemnity  but  for  the   provisions  of  this   Settlement
                    Agreement;  (ii) the efforts that the Non-Settling Defendant
                    has made to reach an accommodation with the Settlement Class
                    Member  with  respect  to the need to name AHP or a Released
                    Party as a defendant in the case;  and (iii) the factual and
                    legal  bases for the  Non-Settling  Defendant's  claim that,
                    under the  particular  facts of the case and the  particular
                    provisions of  applicable  law, the  Non-Settling  Defendant
                    must be  permitted  to name AHP or a  Released  Party in the
                    case despite the bar order.

               c.   A copy of the  Non-Settling  Defendant's  application to the
                    Court  shall be served on Class  Counsel  and on counsel for
                    AHP.

               d.   The  Court   shall   modify   the  bar  order  to  permit  a
                    Non-Settling  Defendant to name AHP or a Released Party in a
                    particular case brought against a Non-Settling  Defendant by
                    a Settlement  Class Member with respect to a Settled  Claim,
                    only  where  doing so is  essential  to  protect  set-off or
                    judgment   reduction   rights  to  which  the   Non-Settling
                    Defendant would be entitled under applicable law but for the
                    provisions of this Settlement Agreement. Any order modifying
                    the bar order  will  contain  provisions  that  protect  the
                    interests of AHP and the Released  Parties in finality under
                    this Settlement  Agreement,  including,  among other things,
                    provisions  affirming that the  Settlement  Class Member has
                    agreed (i) to forego any direct or  indirect  recovery  from
                    AHP or the  Released  Parties  of sums over and above  those
                    received under this Settlement Agreement and (ii) to give up
                    any portion of any judgment  obtained against a Non-Settling
                    Defendant  that is attributed  to AHP or any Released  Party
                    with respect to a Settled Claim.

               e.   Applications    made   by   Non-Settling    Defendants   for
                    modification  of  the  bar  order  will  be  subject  to the
                    provisions of Fed. R. Civ. P. 11.

          3.   For purposes of this Section VII.C of the Settlement Agreement:

               a.   "Non-Settling  Defendant"  shall  mean any  person or entity
                    that is not  AHP or a  Released  Party  as  defined  herein,
                    against  whom  or  which  a  Settled  Claim  has  been or is
                    hereafter made, asserted or commenced.  A physician or other
                    Released  Party may be a  Non-Settling  Defendant  as to any
                    claim with respect to which he, she, or it is not a Released
                    Party.  The term  Non-Settling  Defendant  is not limited to
                    persons or  entities  who are sued in an action in which AHP
                    or another Released Party is also a party.

               b.   "Non-Contractual      Indemnity"     or     "Non-Contractual
                    Indemnification"  means a right of indemnity  based upon the
                    relationship between or conduct of the parties.  These terms
                    include,  and the protections  provided AHP and the Released
                    Parties  herein  apply  to,  a  contractual   obligation  of
                    indemnification voluntarily assumed by AHP to the extent AHP
                    would have been liable to such claimant for indemnity in the
                    absence of such contractual indemnification.

               c.   "Settlement  Class  Member"  shall  mean any  member  of the
                    Settlement  Class who has not timely and properly  exercised
                    an Initial Opt-Out right,  an Intermediate  Opt-Out right, a
                    Back-End  Opt-Out right, or a Financial  Insecurity  Opt-Out
                    right  pursuant  to the  terms of this  Agreement.  Upon the
                    timely and proper exercise of any such opt-out  rights,  the
                    provisions of this Section VII.C shall become ineffective in
                    connection  with any action brought by each Class Member who
                    has timely and properly exercised any such right of opt-out.

          4.   To implement  the bar order  provided for in this Section  VII.C,
               all claims pending against AHP or any other Released Party in any
               court which are  prohibited  by such bar order shall be dismissed
               with prejudice upon Trial Court Approval. Such dismissals will be
               vacated in the event that the  Settlement  does not receive Final
               Judicial Approval.

          5.   In the event any Class  Member who has  received a payment  for a
               Matrix-Level  Condition under this Agreement subsequently obtains
               a judgment or award against a Non-Settling Defendant,  other than
               a physician,  and the Non-Settling Defendant successfully asserts
               a  contractual  indemnity  claim  against  AHP  and/or a Released
               Party,  then,  to the extent not  already  required  by  Sections
               VII.C.1-4  above,  the Class  Member shall reduce the judgment or
               award  against the  Non-Settling  Defendant by the  percentage of
               fault,   liability   or   other    liability-producing    conduct
               attributable to AHP and/or a Released Party. In the event a Class
               Member  who  has  not  received  a  payment  for  a  Matrix-Level
               Condition under this Agreement subsequently obtains a judgment or
               award against a Non-Settling  Defendant,  other than a physician,
               and the Non-Settling Defendant successfully asserts a contractual
               indemnity claim against AHP and/or a Released Party, then, to the
               extent not  already  required by Sections  VII.C.1-4  above,  the
               Class  Member  shall  reduce the  judgment  or award  against the
               Non-Settling  Defendant by the percentage of fault,  liability or
               other  liability-producing  conduct  attributable to AHP and/or a
               Released Party or, in the  alternative,  shall waive any claim to
               additional benefits under this Agreement,  including payments for
               a Matrix-Level Condition.


     D.   PROTECTION OF AHP FROM POSSIBLE SUBROGATION CLAIMS

          1.   To the extent that any person has rights of subrogation by virtue
               of a  payment  or  payments  made  to or for the  benefit  of any
               specific Class Member who has not properly and timely exercised a
               right of opt-out, such rights of subrogation may be asserted with
               respect to the  Trustees'  obligation  to make  payments  to that
               Class  Member  from  Fund B but shall  not be  asserted  directly
               against  AHP and/or  the  Released  Parties  except to the extent
               required by  applicable  Federal or State law. AHP will  promptly
               notify  the  Trustees  and/or  Claims  Administrator(s),  and the
               affected  Class  Member of the  assertion  of such a  subrogation
               claim  against  AHP.  The  Parties  shall  move the  Court,  upon
               granting Trial Court  Approval,  to enter a bar order to preclude
               the assertion of such  subrogation  claims against AHP and/or the
               Released  Parties,   except  to  the  extent  that  it  would  be
               impermissible  to bar such claims under  provisions of applicable
               law.

          2.   The Trustees and/or Claims  Administrator(s) shall provide notice
               of subrogation  claims received by the Trustees to affected Class
               Members and afford  them an  opportunity  to  contest,  otherwise
               object to or compromise any such claims.  In making  distribution
               of any amounts to which Class  Members are entitled  from Fund B,
               the Trustees shall recognize and pay subrogation  claims from the
               amount  otherwise  payable to such Class Member,  but only to the
               extent that the  subrogation  claim is  recognized  by applicable
               law. Unless the law clearly sets forth different principles,  the
               Trustees shall not recognize a subrogation  claim unless:  (1) it
               is affirmatively brought to their attention prior to distribution
               of  Funds  to a  Class  Member;  (2) it is  based  on a  positive
               provision  of  law  or a  valid  enforceable  contract;  (3)  the
               putative subrogee clearly  establishes that the subrogee actually
               made a payment  or  payments  to or for the  benefit of the Class
               Member  which is of a type that the  putative  subrogee  would be
               entitled to recover against AHP and/or the Released Parties,  and
               then (4) only to the  extent of the actual  payment  made less an
               equitable  debit for attorneys'  fees, and any other allowable or
               appropriate charges against the putative subrogee.

     E.   WALKAWAY RIGHTS

          1.   AHP shall  have the option to  terminate  and  withdraw  from the
               Settlement  Agreement,  in its sole  discretion,  based  upon the
               number of persons who have timely and properly elected during the
               Initial Opt-Out Period to be excluded from the Settlement  Class.
               If AHP elects to exercise this  "walkaway  right," it shall do so
               by giving written notice to the Court and to Class Counsel within
               30 days of the close of the  Initial  Opt-Out  Period.  AHP shall
               seek to reach  its  decision  with  respect  to  exercise  of its
               "walkaway right"

          2.   The exercise of this "walkaway  right" by AHP will not affect its
               obligation  to provide the  benefits  to those Class  Members who
               have  accepted  the  Accelerated  Implementation  Option prior to
               AHP's  exercise of its "walkaway  right" or during any subsequent
               period in which AHP continues to offer the AIO.

     F.   LIMITATION ON FINANCIAL OBLIGATIONS

          1.   The maximum  amount that AHP shall be obligated to pay under this
               Settlement  Agreement  shall  be  AHP's  obligation  to make  the
               payments to Fund A and the Escrow  Agent as  specified in Section
               III.B  and  AHP's  obligation  to  make  payments  to  Fund  B in
               accordance with Section III.C. These limitations shall also apply
               to AHP's  obligations  under Individual  Agreements  entered into
               pursuant to the Accelerated Implementation Option.

VIII.    SETTLEMENT IMPLEMENTATION

     A.   GENERAL

          1.   In order to become  effective,  the Settlement must receive Final
               Judicial  Approval,  except as to the Accelerated  Implementation
               Option and as otherwise expressly provided herein.

          2.   The  Parties  recommend  that the  Court  establish  an  Advisory
               Committee  of Class  Counsel,  which  would  consist  of  counsel
               actively involved in State and Federal Diet Drug Litigation.  The
               purpose of the Advisory  Committee of Class  Counsel  would be to
               advise  the  Trustees   concerning   the  proper   operation  and
               implementation of the Settlement Agreement.

     B.   JURISDICTION


          1.   The United  States  District  Court for the  Eastern  District of
               Pennsylvania  will have original and exclusive  jurisdiction over
               all  provisions  of this  Agreement,  including  the creation and
               operation  of the  Settlement  Trust and the award of  attorneys'
               fees  and  reimbursement  of  litigation  expenses,   subject  to
               appropriate participation by State Courts in the manner set forth
               herein.  The Parties  agree and intend that the Court retain such
               exclusive  jurisdiction  for all such  purposes:  (i)  during the
               pendency  of any appeal  taken from Trial  Court  Approval or the
               denial  of Trial  Court  Approval;  and  (ii) if  Final  Judicial
               Approval  is  not  obtained,  subject  to  Section  V.H  of  this
               Agreement.

          2.   In order to  become  effective  as to  Class  Members  who do not
               exercise the Accelerated  Implementation  Option,  the Settlement
               contemplated  by this  Settlement  Agreement  must receive  Final
               Judicial Approval within the federal judicial system.

          3.   A State Court  Judicial  Advisory  Committee  will be established
               within 15 days of  Preliminary  Approval  and will consist of the
               judges from the State Courts  which,  as of October 7, 1999,  had
               issued any order certifying  state-wide class actions in relation
               to the effects of Pondimin(R) and/or Redux(TM).

          4.   The State Court Judicial Advisory  Committee shall provide advice
               and  counsel  to  the  Federal  District  Court  on  all  matters
               pertinent   to  the   Settlement,   including   approval  of  the
               Settlement,  which affect Class Members residing in the States of
               each committee member. In addition,  prior to making any award of
               counsel  fees  and  reimbursement  of  litigation  expenses,  the
               Federal  District  Court shall consult with and give  substantial
               deference  to the  views of the  State  Court  Judicial  Advisory
               Committee  concerning the actual  contribution  which was made to
               the overall  resolution of the  litigation by the attorneys  with
               whom the members of the committee are familiar.

          5.   The  costs  incurred  by  members  of the  State  Court  Judicial
               Advisory Committee in fulfillment of their  obligations,  such as
               expenses  for  travel,  shall  be  reimbursed  as  administrative
               expenses of the Settlement Trust.

          6.   During  the  period  of time  from the date on which the Trust is
               established until December 31, 2004, the majority of the Trustees
               or  Administrators  shall be approved by the State Court Judicial
               Advisory Committee.

     C.   APPROVAL PROCESS AND NOTICE PROVISIONS

          1.   Within 10 days after executing this Agreement,  the Parties shall
               jointly  move the  Court,  by filing a motion for the entry of an
               order  granting  Preliminary  Approval,  in the form  attached as
               Exhibit "11". Such Order shall  preliminarily  and  conditionally
               appoint the  Plaintiffs in Sheila Brown,  et al. v. American Home
               Products   Corporation  as  the  Class   Representatives  of  the
               Settlement Class and of each of Subclasses 1(a), 1(b), 2(a), 2(b)
               and 3;  preliminarily and conditionally  appoint counsel for such
               plaintiffs   as  Class   Counsel   for  the   Settlement   Class;
               preliminarily and conditionally certify the Settlement Class, for
               Settlement  purposes  only;  grant  Preliminary  Approval of this
               Agreement;  approve the  appointment  of the Interim Escrow Agent
               and Interim Claims Administrator(s);  authorize the dissemination
               of the Settlement notice in accordance with Section VI.B. hereof;
               designate the Initial  Opt-Out  Period to terminate 90 days after
               the date on which  publication  and/or  mailing of the Settlement
               notice   commences  in   accordance   with  the  Order   granting
               Preliminary Approval;  schedule the date for filing objections to
               the Settlement;  and schedule a formal fairness hearing to review
               comments  concerning  this  Agreement,  to consider its fairness,
               reasonableness  and  adequacy  under Fed. R. Civ. P. 23(e) and to
               determine whether an Order should be entered granting Trial Court
               Approval.

          2.   Fund A will pay 50%,  and Fund B will pay 50% of the total  costs
               of printing,  publishing and otherwise  disseminating the notice.
               In the event that the Settlement  does not receive Final Judicial
               Approval,   the  costs  of  printing,   publishing  or  otherwise
               disseminating  notice shall be borne by AHP,  and the  Settlement
               Trust will  therefore have no obligation to return or refund such
               costs to AHP.

          3.   AHP shall  retain its right to contest  class  certification  for
               litigation purposes.

          4.   The Parties shall  cooperate and assist in all of the filings and
               proceedings  relating to the obtaining of Preliminary Approval as
               well as Trial  Court  Approval  and in any  further  filings  and
               proceedings  necessary to obtain Final  Judicial  Approval of the
               Settlement, and in any related appeals.

          5.   Upon Final  Judicial  Approval,  the Class  Counsel and all Class
               Members shall  cooperate with AHP and any other Released Party to
               cause the dismissal,  with  prejudice and without  costs,  of any
               action  against  AHP or any  Released  Party  asserting a Settled
               Claim  brought  by or on behalf of any Class  Member  who has not
               timely and properly exercised an Initial Opt-Out right, including
               but not limited to class  actions,  whether or not  certified  as
               such,  which are  pending  in any state,  federal or  territorial
               court. Upon Trial Court Approval,  the Class Counsel and all such
               Class Members  shall  cooperate  with AHP and any other  Released
               Party to cause further proceedings in all such settled actions in
               which the Class Members did not timely and properly opt out to be
               stayed pending Final Judicial Approval.

     D.   CONDITIONS

          1.   AHP's   obligations   under  this   Agreement,   other  than  its
               obligations to Class Members who accept the AIO during the period
               in which it is available for  acceptance,  will be subject to the
               following conditions:

               a.   Trial Court Approval of the Settlement, which approval order
                    or orders shall:

                         23(c)(1) and 23(e), for Settlement purposes only;

                    (2)  Confirm the  appointment  of the  plaintiffs  in Sheila

                         non-collusive;

                    (4)  Dismiss with  prejudice  and without  costs the Amended
                         Complaint  in Sheila  Brown,  et al. v.  American  Home
                         Products  Corporation,  as well as all other  claims or
                         actions  asserting  Settled  Claims against AHP pending
                         before  the  Court,   with  the  condition   that  such
                         complaints  may be  reinstated  in the event that Final
                         Judicial Approval is not obtained;

                    (5)  Bar and  enjoin all Class  Members  who have not timely
                         and  properly   exercised   an  Initial   Intermediate,
                         Back-End,  or Financial  Insecurity  Opt-Out right from
                         asserting and/or continuing to prosecute against AHP or

                         which the Class  Member  had,  has,  or may have in the
                         future in any federal, state or territorial court;

                    (6)  Bar and enjoin the commencement  and/or  prosecution of
                         any  claim  for  contribution  and/or   non-contractual
                         indemnity, pursuant to Section VII.C hereof and subject
                         to the provisions of Section  VII.C.2,  in any federal,
                         state or  territorial  court  against  AHP or any other
                         Released Party by any  Non-Settling  Defendant  arising
                         from or relating to any Settled  Claim  asserted by any

                    (7)  Bar and enjoin the commencement  and/or  prosecution of
                         any claim or action  against AHP in any federal,  state
                         or territorial  court based on rights of subrogation by
                         virtue  of a  payment  or  payments  made to or for the
                         benefit of a Class Member arising out of or in relation
                         to any  Settled  Claims,  except to the extent  that it
                         would  be   impermissible  to  bar  such  claims  under
                         provisions of applicable law;

                    (8)  Reserve   the   Court's    continuing   and   exclusive
                         jurisdiction  over the Parties,  including  AHP and the
                         Class Members, to administer, supervise, interpret, and
                         enforce this Agreement in accordance with its terms and
                         to supervise the operation of the Settlement Trust; and

                    (9)  Enter such other orders as are needed to effectuate the
                         terms of the Settlement;

          2.   AHP may at its election  terminate this  Settlement  Agreement if
               the Final Judicial  Approval does not meet all the conditions set
               forth in Section VIII.D.1.a above.

     E.   ATTORNEYS' FEES

          1.   In  the  event  that  the  Settlement   receives  Final  Judicial
               Approval,  the Court  shall  award  counsel  fees and  litigation
               expenses  from  the  Settlement  funds  to  those  attorneys  who
               actually  contributed  to the  creation of the  Settlement  funds
               through  work devoted to the "common  benefit" of Class  Members,
               including any attorney who actually  conferred  benefits upon the
               class through State Court litigation ("Common Benefit Attorneys")
               and may award Class Action  Representative  Incentive Fees to the
               certified  State  and  Federal  Court  Class  Representatives  in
               accordance with  applicable  principles of law and subject to the
               following provisions.

               a.   As  provided  in this  Section,  AHP  agrees to pay to Class
                    Counsel,  Common Benefit  Attorneys and the certified  State
                    and  Federal  Class  Action   Representatives   fees  in  an
                    aggregate  amount of up to  $200,000,000,  together with any
                    accrued  interest  thereon from the date of deposit into the
                    Fund A Escrow Account,  for the services  related to Fund A,
                    subject to  approval  by the Court.  To the extent that such
                    fees are  awarded  by the  Court,  they shall be paid by the
                    Escrow  Agent  from the  escrow  account  into  which AHP is
                    required to deposit  said amounts for that  purpose,  as set
                    forth above in Section III.B.3 (Fund A Escrow Account)

               b.   Attorneys'  fees  relating to Fund B shall be paid from Fund
                    B. For purposes of awarding attorneys' fees from Fund B, AHP
                    agrees that  attorneys' fees should be awarded and paid as a
                    percentage of or otherwise  based on the net present  value,
                    as of the  Final  Judicial  Approval  Date,  of the  maximum
                    amounts which AHP may be legally  obligated to pay to Fund B
                    for the benefit of the Settlement  Class,  regardless of the
                    amount of claims  actually  paid at any given point in time,
                    pursuant to the  principle  expressed  in the case law,  see
                    Boeing v. Van  Gemert,  444 U.S.  472  (1980).  The  Parties
                    stipulate that, only for purposes of calculating  payment of
                    attorneys'  fees,  the net  present  value,  as of the Final
                    Judicial Approval Date, of the maximum amounts which AHP may
                    be legally obligated to pay to Fund B for the benefit of the
                    class is $2,550,000,000.  The Parties further agree that the
                    attorneys'  fees  payable  from  Fund B to  counsel  for the
                    Settlement  Class  ("Class   Counsel")  and  Common  Benefit
                    Attorneys  from Fund B shall not exceed $229 million,  which
                    is 9% of the  $2,550,000,000  dollar  amount,  and  that the
                    actual amount of  attorneys'  fees shall be as determined by
                    the Court.  An amount  shall be deducted  from each  payment
                    made to a Class  Member from Fund B in an amount equal to 9%
                    of the total Matrix  payment due the Class Member before any
                    deductions.  Individual Class Members who are represented by
                    attorneys  entitled  to a  contingent  fee  under  any valid
                    written  contingent  fee  agreement  with such Class  Member
                    shall be subject to a further  reduction for attorneys' fees
                    due to their  attorney.  The  amount to be paid to the Class
                    Member's  attorney  shall be the  total  attorneys'  fee due
                    under the terms of the contingency  fee arrangement  less 9%
                    of the total Matrix  payment due to the Class Member  before
                    any    deductions.    Fund   B   payments    to   any   such
                    individually-represented Class Members shall also be reduced
                    by the  amount  of  reasonable  out-of-pocket  costs of such
                    Class  Member's  attorney  to the extent  authorized  in the
                    document  evidencing  such  attorney's   retention  and  the
                    individual attorneys' agreement with the Class Member and to
                    the extent  permitted or allowed by applicable  law in which
                    the agreement was entered.  It is expected that the Trustees
                    will  not  honor  contingent  fee  agreements  with  private
                    counsel  which were entered into in violation of  applicable
                    law.  In the event that the Trial  Court has not entered any
                    order with  respect to the payment of  attorneys'  fees from
                    Fund B by the end of the first Fiscal  Quarter,  then within
                    five  business  days  after  the  end  of the  first  Fiscal
                    Quarter,  AHP shall  establish  and  thereafter  maintain an
                    interest-bearing escrow account (the "Fund B Attorneys' Fees
                    Account") in the amount of $229 million,  for payment of the
                    maximum  attorneys'  fees payable  under this  section.  The
                    establishment  and  funding of such Fund B  Attorneys'  Fees
                    Account shall reduce the Adjusted  Maximum  Available Fund B
                    Amount  as of that  time  in the  same  fashion  as a Fund B
                    Deposit  Amount.  All income earned by the Fund B Attorneys'
                    Fees  Account  shall  remain  in and be  added to the Fund B
                    Attorneys'  Fees  Account,  except that any taxes payable on
                    such income shall be paid out of such income.  The amount in
                    the Fund B Attorneys'  Fees Account shall be available to be
                    distributed  as  attorneys'  fees as  directed  by the Trial
                    Court or by a court with  appellate  jurisdiction  over such
                    ruling.  Any  portion  of the  total  balance  in the Fund B
                    Attorneys'  Fees Account not finally  awarded as  attorneys'
                    fees shall be paid to AHP within  five  business  days after
                    the order regarding such fees becomes final and the Adjusted
                    Maximum Available Fund B Amount shall be increased as of the
                    date of such payment by the total amount paid to AHP.

               c.   If the Court awards less than 9% of the present value amount
                    stated  above as payment  for the  attorneys'  fees of Class
                    Counsel and Common Benefit  Attorneys from Fund B, the Court
                    shall  direct that  appropriate  adjustments  be made in the
                    distribution  of Fund B amounts to Class  Members  and their
                    individual attorneys,  including,  if necessary,  additional
                    payments  to Class  Members  and  individual  attorneys  who
                    received Fund B distributions  prior to the Court's decision
                    concerning  the award of counsel  fees to Class  Counsel and
                    Common Benefit Attorneys.

          2.   In the event that the Settlement  does not receive Final Judicial
               Approval or is terminated by AHP for any reason, AHP shall make a
               payment for attorneys'  fees for Fund A benefits paid or provided
               under the AIO to an  account  to be  established,  subject to the
               supervision of the Court.  The first such payment shall be in the
               amount of 20% of the dollar value of all Fund A benefits  paid or
               provided to individuals  under the AIO as of the date of such fee
               payment.  At quarterly intervals  thereafter,  AHP shall pay into
               the  account an amount  equal to 20% of the  dollar  value of all
               Fund A benefits  paid or  provided to  individuals  under the AIO
               during the preceding quarter.  Any amounts paid into this account
               which are not awarded in attorneys' fees shall be returned to AHP
               by order of the Court. Any attorney who reasonably  believes that
               he or she actually conferred  benefits upon individuals  electing
               the AIO through  State Court  litigation,  may apply to the Court
               for a portion of the amount  deposited  in such  account  and may
               receive  payment of such common  benefit fees in accordance  with
               applicable  provisions  of law.  Those  accepting  the  AIO  must
               expressly  agree to this provision  regarding fees as a condition
               to exercising the option.  This paragraph  shall not be construed
               to require AHP to make any payment for attorneys' fees for Fund A
               benefits prior to Final Judicial  Approval  unless this Agreement
               is terminated prior to that date.

          3.   Prior to the time that the  Settlement  receives  Final  Judicial
               Approval  or in the event that the  Settlement  does not  receive
               Final  Judicial  Approval or is terminated by AHP for any reason,
               AHP shall deduct from any Fund B benefits paid to those accepting
               the AIO an amount equal to 9% of the total Matrix  payment due to
               the Class Member  before any  deductions  and shall  deposit such
               amounts in the  account  to be  established  pursuant  to Section
               VIII.E.2 above.  At such time as the Settlement  fails to receive
               Final  Judicial  Approval or is terminated by AHP for any reason,
               any  attorney  who  reasonably  believes  that he or she actually
               conferred  benefits  upon  individuals  electing  the AIO through
               State Court  litigation,  may apply to the Court for a portion of
               the amount  deposited in such account and may receive  payment of
               such common benefit fees and costs in accordance  with applicable
               provisions of law.  Individual  Class Members who are represented
               by attorneys entitled to a contingent fee under any valid written
               contingent  fee agreement with such Class Member shall be subject
               to a further reduction for attorneys' fees due to their attorney.
               The amount to be paid to the Class Member's attorney shall be the
               total  attorneys' fee due under the terms of the  contingency fee
               arrangement  less 9% of the total Matrix payment due to the Class
               Member before any  deductions.  Payment of Fund B benefits to any
               such individually-represented  Class Member shall also be reduced
               by the  amount of  reasonable  out-of-pocket  costs of such Class
               Member's  attorney  to the  extent  authorized  in  the  document
               evidencing  such attorney's  retention and individual  attorney's
               agreement  with the Class  Member and to the extent  permitted or
               allowed by law. Those  accepting the AIO must expressly  agree to
               this  provision  regarding  fees as a condition to exercising the
               option.  If the Court  awards  less than 9% of the amount  stated
               above as payment  for the  attorneys'  fees of Class  Counsel and
               Common  Benefit  Attorneys  from the amount  paid to  individuals
               accepting  the AIO,  the  Court  shall  direct  that  appropriate
               adjustments be made in the  distribution of these fund amounts to
               individuals  accepting  the AIO and their  individual  attorneys,
               including,  if necessary,  additional payments to individuals who
               accepted  the AIO and their  individual  attorneys  who  received
               payment  prior to the Court's  decision  concerning  the award of
               counsel fees to Class Counsel and Common Benefit Attorneys.

          4.   In  the  event  that  the  Settlement   receives  Final  Judicial
               Approval,  no additional  attorneys' fees or litigation  expenses
               shall be paid for  benefits  conferred on those  individuals  who
               accepted the AIO.

          5.   The  Parties  shall  recommend  that  the  Court  enter  an Order
               precluding a Class Member's individual attorney from recovering a
               fee in  connection  with the  recovery of the $3,000 cash benefit
               provided by Section  IV.A.2.c or the $6,000 cash benefit provided
               by Section  IV.A.1.c,  which is greater than 20% of such amounts.
               This 20% fee for a Class Member's  individual  attorney shall not
               be  affected  by fees paid to Class  Counsel  or  Common  Benefit
               Attorneys, pursuant to the Court's order.

     F.   OTHER PROVISIONS

          1.   Any  information  provided  by or  regarding  a Class  Member  or
               otherwise  obtained  pursuant  to this  Agreement  shall  be kept
               confidential  and shall not be  disclosed  except to  appropriate
               persons to the  extent  necessary  to  process  Claims or provide
               benefits under this Agreement or as otherwise  expressly provided
               in this  Agreement.  All  Class  Members  shall be deemed to have
               consented  to  the  disclosure  of  this  information  for  these
               purposes.

          2.   This Settlement  Agreement shall be binding on the successors and
               assigns of the Parties.

          3.   The  Parties  to the  Settlement,  including  AHP,  the  Released
               Parties, or any Class Member,  shall not seek to introduce and/or
               offer  the  terms of the  Settlement  Agreement,  any  statement,
               transaction  or proceeding in  connection  with the  negotiation,
               execution or  implementation  of this Settlement  Agreement,  any
               statements in the notice  documents  appended to this  Settlement
               Agreement,  stipulations,   agreements,  or  admissions  made  or
               entered  into in  connection  with the  fairness  hearing  or any
               finding of fact or conclusion of law made by the Trial Court,  or
               otherwise rely on the terms of this  Settlement,  in any judicial
               proceeding,  except  insofar as it is  necessary  to enforce  the
               terms of the  Settlement.  If a Class  Member  who has timely and
               properly  exercised an Opt-Out  right seeks to  introduce  and/or
               offer any of the matters described herein in any proceeding,  the
               restrictions  of this Section  shall not be applicable to AHP and
               the Released Parties with respect to that Class Member.

          4.   Neither this  Agreement  nor any exhibit,  document or instrument
               delivered  hereunder  nor  any of the  statements  in the  notice
               documents appended to this Settlement  Agreement or in connection
               herewith,  nor  any  statement,   transaction  or  proceeding  in
               connection with the negotiation,  execution or  implementation of
               this  Agreement,  is intended to be or shall be  construed  as or
               deemed to be evidence of an admission or concession by AHP or the
               Released  Parties of any  liability or wrongdoing or of the truth
               of any allegations  asserted by any plaintiff against it or them,
               or as an admission by the Class Representatives or members of the
               Settlement  Class of any lack of  merit in their  claims,  and no
               such statement,  transaction or proceeding shall be admissible in
               evidence  for any such  purpose  except for purposes of obtaining
               approval  of this  Settlement  Agreement  in  this  or any  other
               proceeding.

          5.   The headings of the sections and paragraphs of this Agreement are
               included  for  convenience  only  and  shall  not  be  deemed  to
               constitute part of this Agreement or to affect its construction.

          6.   As soon as  practicable  after the  execution  of the  Settlement
               Agreement,  the Parties shall take all steps which are reasonably
               necessary to enable the Trustees  and/or Claims  Administrator(s)
               promptly to provide Fund A benefits upon Final Judicial  Approval
               to all Class Members not exercising Initial Opt-Out rights.  This
               includes   reasonable  and  necessary   steps  to  establish  the
               Settlement  Trust;  to  establish  a  mechanism  to  operate  the
               Settlement Trust and administer  claims; to solicit,  receive and
               process  claims from Class  Members  which will be  necessary  to
               provide  benefits to Class  Members;  to establish a mechanism to
               provide  medical  screening,  services and cash to members of the
               class;  to  communicate  with Class Members and like  activities.
               These  expenses  shall not exceed  $45  million,  or such  higher
               amount as may be  requested  in  writing  by the  Interim  Claims
               Administrators  and/or Trustees,  agreed upon by the Parties, and
               approved by the Court.  In the event that the  Settlement  is not
               approved,  AHP will  not be  entitled  to a refund  of any of the
               money spent for these purposes.

          7.   Any notice, request, instruction or other document to be given by
               AHP to Class  Counsel or Class Counsel to AHP shall be in writing
               and delivered  personally or sent by Federal Express or facsimile
               as follows,  or as otherwise  instructed by a notice delivered to
               the other Party pursuant to this subsection:

               a.   If to AHP:

                    Louis L. Hoynes, Jr., Esquire
                    Senior Vice President and General Counsel
                    American Home Products Corporation
                    5 Giralda Farms
                    Madison, NJ 07940-0874

               b.   If to the Class Representatives or Class Counsel:

                    Arnold Levin, Esquire
                    Levin, Fishbein, Sedran & Berman
                    510 Walnut Street
                    Suite 500
                    Philadelphia, PA 19106

                    Gene Locks, Esquire
                    Greitzer & Locks
                    1500 Walnut Street
                    20th Floor
                    Philadelphia, PA  19102

          8.   Any form or other  documentation  required to be submitted  under
               this Agreement  shall be deemed timely if postmarked on or before
               the date by which  it is  required  to be  submitted  under  this
               Settlement   Agreement.   Subject   to   other   provisions   for
               eligibility,  a properly  completed  and executed AIO  Individual
               Agreement  or Opt-Out  Form will be  effective  on the date it is
               postmarked.

          9.   No provision of this Settlement  Agreement or any Exhibit thereto
               is  intended  to  create  any  third-party  beneficiary  to  this
               Settlement Agreement.

          10.  Upon execution of the Memorandum of  Understanding  dated October
               7, 1999  ("MOU"),  AHP and Class  Counsel  jointly  established a
               toll-free  telephone  number and website  for persons  requesting
               additional information regarding the Settlement.  This number and
               website  has been and shall  continue  to be used to  record  the
               names and addresses of such individuals and other information, so
               that individual  notice concerning the Settlement may be provided
               to  them.  These  names  and  addresses  shall  be kept  strictly
               confidential and shall not be disclosed to any person or used for
               any purpose  other than for  issuance of  settlement  notice upon
               prior  order of the Court  pursuant to Section  VI.B.1.f(3).  AHP
               shall pay all costs relating to the toll-free  telephone line and
               website. In the event that the settlement receives Final Judicial
               Approval,  all  expenditures  made  by  AHP  in  relation  to the
               toll-free   telephone   line  and  website  shall  be  considered
               administrative expenses of Fund A, and AHP shall receive a credit
               in the amount of all such  expenditures  in calculating  its next
               payment to Fund A.

          11.  This Agreement  contains the entire Agreement between the Parties
               with  respect to the subject  matter  hereof and  supersedes  and
               cancels all previous Agreements, negotiations, and commitments in
               writings  between the Parties  hereto with respect to the subject
               matter  hereof,   including  without  limitation  the  MOU.  This
               Agreement  may not be changed or modified in any manner unless in
               writing and signed by a duly  authorized  officer of AHP and by a
               duly authorized representative of the Class Representatives.

IN WITNESS WHEREOF,  the Parties have duly executed this Nationwide Class Action
Settlement  Agreement  between American Home Products  Corporation and the Class
Representatives,  by their respective  counsel as set forth below, on this _____
day of November, 1999.
