     SECTION 4. DEFERRED COMPENSATION PARTICIPANT

     Prior to the beginning of any calendar  quarter in each calendar  year, any
Director  who is not an  employee  of the  Company  may  defer  the  receipt  of
Compensation to be earned by the Director  during such calendar  quarter and the
ensuing calendar quarters by filing with the Company a written election that:

          (i) defers  payment of a designated  amount (of One  Thousand  Dollars
     ($1,000) or more) or a  percentage  of his/her  Compensation  for  services
     attributable to such calendar quarters (the "Deferred Amount");

          (ii) specifies the payment option selected by the Participant pursuant
     to Section 7.2 hereof for such Deferred Amount; and

          (iii) specifies the options  selected by the  Participant  pursuant to
     Section 5 hereof for such Deferred Amount.

     The amount  deferred  may not exceed the  Director's  Compensation  for the
period of deferral.  Notwithstanding the foregoing, any individual who is not an
employee of the  Company,  and who is newly  elected or  appointed to serve as a
Director  may,  not later  than  thirty  (30) days  after  his/her  election  or
appointment  as a  Director  becomes  effective,  elect in  accordance  with the
preceding  provisions  of this  Section 4, to defer the receipt of  Compensation
earned during the portion of the current  calendar  quarter that follows his/her
filing of the election  with the Company.  Any  elections  made pursuant to this
Section 4 shall be irrevocable  when made.  Notwithstanding  the foregoing,  the
Board  of  Directors  in its  sole  discretion,  may  make a  distribution  to a
Participant  under either  Section  7.2(i)(a) or 7.4. If a Participant  fails to
discontinue an election under Section 5 with respect to his/her  Deferred Amount
for a future period, the Participant's  current election shall remain in effect,
provided,  however, that the Participant may thereafter make a new election with
regard to a future period at any time in accordance  with the first paragraph of
this Section 4.

                SECTION 5. FORM OF DEFERRED COMPENSATION CREDITS

     5.1. Deferred Compensation Account.  Except with respect to the deferral of
Compensation for a quarter in which a Deferred  Compensation  Participant elects
to have all or a  percentage  of the  Deferred  Amount  credited  in  Shares  in
accordance with Section 5.2 hereof,  the Deferred Amount shall be denominated in
U.S. dollars and credited to the  Participant's  Deferred  Compensation  Account
pursuant to Section 6.1 hereof.

     5.2.  Shares.  Prior to the beginning of any calendar  quarter,  a Deferred
Compensation  Participant may elect, by filing a written election with the Board
of  Directors,  to have  all or a  percentage  of the  Deferred  Amount  for the
following  calendar quarter and/or ensuing calendar  quarters  credited in Share
Equivalents and allocated to the Participant's  Vested Share Account pursuant to
Section 6.2 hereof.  Any  elections  made  pursuant to this Section 5.2 shall be
irrevocable  when made. If a Participant  fails to discontinue an election under
this  Section 5 with  respect to his/her  Deferred  Amount for a future  period,
his/her current  election shall remain in effect,  provided,  however,  that the
Participant may thereafter make a new election with regard to a future period at
any time.

     5.3.  Transfer of Deferred  Compensation  Account Balance to Share Account.
Prior to the effective date of the Plan, a Deferred Compensation Participant may
elect to have all or a portion of his/her final credited  account balance in the
Prior  Plan ( i.e.,  the  balance  as of  April  30,  1997)  converted  to Share
Equivalents  and  credited  to the  Participant's  Vested  Share  Account.  Such
conversion  shall  take place as of May 1, 1997,  based on the  Average  Closing
Price as of May 1, 1997.

     5.4. Transfer of Present Value of Accrued Benefits Under Retirement Plan to
Share Account Prior to the effective  date of the Plan, a Deferred  Compensation
Participant  shall have allocated to his/her  Unvested  Share  Account,  or if a
Participant has satisfied the vesting  requirements set forth in Section 5.5(ii)
hereof,  to  his/her  Vested  Share  Account,  the  number of Share  Equivalents
(maintained  in  fractions  and  rounded to three (3) decimal  places)  having a
market value  (calculated  as set forth below)  equal to the  actuarial  present
value  as of May 1,  1997,  of the  amount  that  would  have  been  due to such
Participant  under the American Home Products  Corporation  Retirement  Plan for
Outside Directors at the time of his/her earliest  retirement date assuming that
the Participant  has then satisfied the vesting  requirements  thereunder.  Such
actuarial  present  value  calculation  shall be performed by the Company in its
discretion  and shall be  converted  to Share  Equivalents  and  credited to the
Participant's  Unvested  or  Vested  Share  Account,  as the case  may be.  Such
conversion  shall  take place as of May 1, 1997,  based on the  Average  Closing
Price as of that date.

     5.5. Vesting of Unvested Share Account.

          (i)  All  amounts  transferred   pursuant  to  Section  5.4  shall  be
     maintained  in a Vested Share  Account to the extent  vested at the time of
     transfer.  All  amounts  which are not vested  will be held in an  Unvested
     Share  Account  until the  Participant  shall have  satisfied  the  vesting
     requirements  set forth in Section  5.5(ii),  at which time such amounts in
     the  Participant's  Unvested Share Account shall be  transferred  from such
     Unvested  Share  Account  and  shall  become  a part of or be  added to the
     Participant's Vested Share Account.

          (ii) A Participant shall have satisfied the vesting  requirements upon
     completion  of at least ten (10) Years of  Service  and  attainment  of age
     sixty-five (65), provided,  however,  that a Participant who ceases to be a
     Director prior to attainment of age sixty-five  (65) with at least ten (10)
     Years of Service shall be deemed to have satisfied the vesting requirements
     upon the  first to occur of (1)  attainment  of age  sixty-five  (65),  (2)
     death, or (3) Disability.

                         SECTION 6. INDIVIDUAL ACCOUNTS

     The  Company  shall  maintain  Individual  Accounts  for  Participants,  as
follows:

     6.1. Deferred  Compensation  Account. The Company shall maintain a Deferred
Compensation Account in the name of each Deferred Compensation  Participant with
respect to any amounts  deferred under the Plan which the Deferred  Compensation
Participant  does not elect to have  credited in Share  Equivalents  pursuant to
Section 5.2 or 5.3 hereof.  The opening balance of each  Participant's  Deferred
Compensation  Account on the  effective  date of this Plan shall be equal to the
closing balance on the immediately  preceding date of the corresponding  account
maintained  on the  Participant's  behalf under the Prior Plan, if any, less any
portion of such account  converted  to Share  Equivalents  and  allocated to the
Participant's  Vested Share Account pursuant to Section 5.3 hereof. The Deferred
Compensation  Account  shall be  denominated  in U.S.  dollars,  rounded  to the
nearest  whole cent.  A Deferred  Amount  allocated  to a Deferred  Compensation
Account  pursuant  to  Section  5.1 hereof  shall be  credited  to the  Deferred
Compensation Account as of the Deferral Allocation Date.

     6.2. Share Accounts.  The Company shall maintain Share Accounts  consisting
of (i) a Vested  Share  Account and (ii) an Unvested  Share  Account.  The Share
Accounts shall be denominated in Share  Equivalents,  and shall be maintained in
fractions rounded to three (3) decimal places. Share Equivalents  allocated to a
Deferred  Stock  Participant's  Vested  Share  Account  in  accordance  with the
Participant's  election  under  Section  5.2  hereof,  shall be  credited to the
Participant's  Vested  Share  Account as of the  Deferral  Allocation  Date next
occurring  in  January,  April,  July or  October  (each a  "Quarterly  Deferral
Allocation Date"), provided that a Deferred Amount so credited shall be credited
with deemed  interest at the Company Credit rate  calculated in accordance  with
Section 6.3 from the actual Deferral  Allocation  Date, if different,  until the
day preceding the next Quarterly  Deferral  Allocation Date.  Share  Equivalents
and,  if  necessary,  fractional  Share  Equivalents,  shall  be  credited  to a
Participant's  Vested Share  Account  based on the Average  Closing Price at the
Deferral Allocation Date.

     6.3.  Accrual  of  Company  Credit.  The  Treasurer  of the  Company  shall
determine  the annual  rate of Company  Credit on or before  December 31 of each
calendar year. This rate shall be effective for the following calendar year. The
Company  Credit shall be compounded  and credited to each Deferred  Compensation
Account  as of the last day of each  calendar  quarter  for each  month (or part
thereof) that the Participant serves as a Director during such calendar quarter.
If a Participant  elects the payment  option under either  Section  7.2(i)(b) or
Section 7.2(i)(c) below, the Company Credit shall continue to be credited to the
Participant's account until distributed.

     6.4. Cash Dividends.  Cash dividends paid on Shares shall be deemed to have
been  paid  on the  Share  Equivalents  allocated  to each  Participant's  Share
Accounts and shall be treated as if the allocated Share  Equivalents were actual
Shares issued and  outstanding  on the Dividend  Record Date. An amount equal to
the amount of such  dividends  shall be  credited in Share  Equivalents  to each
Share Account as of each Dividend  Allocation  Date based on the Average Closing
Price at the Dividend Allocation Date.

     6.5.  Capital  Adjustments.  The number of Share  Equivalents  allocated to
Share  Accounts  shall  be  adjusted  by the  Board  of  Directors,  as it deems
appropriate,  to  reflect  stock  dividends,  stock  splits,  reclassifications,
spinoffs, and other extraordinary  distributions,  as if those Share Equivalents
were actual Shares.

     6.6. Account Statements. Within a reasonable time following the end of each
calendar  year,   the  Company  shall  provide  an  annual   statement  to  each
Participant.  The annual statement for each Participant  shall report the number
of  Share  Equivalents  credited  to each of the  Participant's  Share  Accounts
(together with the dollar amount of any cash accruing  interest pending the next
Quarterly Deferral  Allocation Date) and shall report the dollar amount credited
to the  Participant's  Deferred  Compensation  Account as of December 31 of that
year.

                          SECTION 7. PAYMENT PROVISIONS

     7.l.   Method  of  Payment.   All  payments  to  a  Participant  (or  to  a
Participant's  Beneficiary  or estate,  as the case may be) with  respect to the
Participant's  Deferred  Compensation  Account and Vested Share Account shall be
paid in cash only,  with Share  Equivalents  valued as set forth in Section  7.2
below.

     7.2. Payment Options

          (i) At the time  each  Director  elects  to make a  deferral  or,  for
     Participants  who are Directors on May 1, 1997, prior to the effective date
     of the Plan, the Participant  shall select a payment option with respect to
     the payment of the  Participant's  Individual  Accounts  from the following
     payment options:

               (a) a lump sum paid on the  first  business  day of the  calendar
          quarter following the calendar quarter in which the Participant ceases
          to be a Director;

               (b) payments in substantially  equal annual  installments  over a
          period  of  between  two (2) to ten  (10)  years,  as  elected  by the
          Participant  at the time  he/she  makes  his/her  election  under this
          paragraph (i)(b), commencing in January of the calendar year following
          the calendar year during which the Participant ceases to be a Director
          with Share  Equivalents  in the  Participant's  Vested  Share  Account
          treated as described in paragraph (iii) below; or

               (c) payments in annual  installments over a period of between two
          (2) to ten (10) years as elected by the Participant at the time he/she
          makes his/her  election  under this  paragraph  (i)(c),  commencing in
          January of the calendar year  following the calendar year during which
          the Participant ceases to be a Director, with Share Equivalents in the
          Participant's  Vested Share Account  treated as described in paragraph
          (iv) below.

          (ii) If the payment  option  described in  paragraph  (i)(a) above has
     been elected,  the amount of the lump sum with respect to the Participant's
     Deferred  Compensation Account shall be equal to the amount credited to the
     Participant's  Deferred Compensation Account as of the last business day of
     the calendar quarter  preceding the date of payment,  and the amount of the
     lump sum with respect to the  Participant's  Vested Share  Account shall be
     equal to the Average  Closing Price as of last business day of the calendar
     quarter  preceding  the date of payments  multiplied by the number of Share
     Equivalents  credited to the Participant's  Vested Share Account as of such
     date plus any cash accruing  interest  pending the next Quarterly  Deferral
     Allocation Date.

          (iii) If the payment  option  described in paragraph  (i)(b) above has
     been elected,  the value of the Participant's Vested Share Account shall be
     added to the amount in such  Participant's  Deferred  Compensation  Account
     based on the Average Closing Price at the date of the first payment and the
     amount of each  installment  with  respect  to the  Participant's  Deferred
     Compensation   Account   (including   the  amount   transferred   from  the
     Participant's  Vested Share Account and any cash accruing  interest pending
     the next Quarterly  Deferral  Allocation  Date) shall be paid annually,  in
     substantially equal installment amounts. The determination of the amount of
     substantially   equal  installment   payments  shall  be  a  fixed  annuity
     computation  determined based on the amount of the  Participant's  Deferred
     Compensation   Account   (including   the  amount   transferred   from  the
     Participant's  Vested Share Account) at the time of the first payment,  the
     annual  rate  of the  Company  Credit  at  that  time  and  the  number  of
     installments  selected,  assuming  compounding  of the Company  Credit on a
     quarterly basis.

          (iv) If the payment  option  described in  paragraph  (i)(c) above has
     been  elected,   the  amount  of  each  installment  with  respect  to  the
     Participant's  Deferred  Compensation Account and Vested Share Account (and
     any cash accruing interest pending the next Quarterly  Deferral  Allocation
     Date) shall be paid  annually,  in  installment  amounts.  The amount to be
     distributed annually with respect to Share Equivalents shall be computed by
     dividing the number of Share Equivalents in the Participant's  Vested Share
     Account by the number of installment payments selected,  with the resulting
     number of Share  Equivalents  paid in cash,  based on the  Average  Closing
     Price as of the December 31 preceding each date of payment.  Any additional
     amounts in respect of Share  Equivalents  relating to dividend  equivalents
     during the duration of installment payments shall be included with and paid
     as part of the last installment.

          (v) If the  Participant  fails to elect a payment  option,  the amount
     credited  to the  Participant's  Deferred  Compensation  Account and Vested
     Share Account  shall be  distributed  in a lump sum in accordance  with the
     payment option  described in paragraph (i)(a) and paragraph (ii) above. If,
     at the time a Participant ceases to be a Director, the amount credited to a
     Participant's   Deferred  Compensation  Account  and  the  value  of  Share
     Equivalents credited to a Participant's Share Accounts is less than $25,000
     in the aggregate,  the Board of Directors, in its sole discretion,  may pay
     out  the  amount  credited  to  such  Account  in a  lump  sum  as if  such
     Participant elected distribution under paragraph (i)(a) above.

          (vi)  Notwithstanding  the foregoing,  any amounts in a  Participant's
     Unvested Share Account at the time the Participant  ceases to be a Director
     shall be (a)  forfeited if the  Participant  has not completed at least ten
     (10) Years of Service, or (b) if the Participant has completed at least ten
     (10)  Years of  Service,  shall be paid to the  Participant,  in the manner
     selected in paragraph  (i)(a),  (i)(b),  or (i)(c) above, upon the first to
     occur  of  (1)  attainment  of age  sixty-five  (65),  or  (2)  Disability,
     provided, however, that if the payment option described in paragraph (i)(a)
     above has been selected,  the value of such Unvested Share Account shall be
     determined  based  on the  Average  Closing  Price  as of the  December  31
     preceding  the date of payment , and  thereafter  shall be treated as if it
     were  part  of the  Participant's  Deferred  Compensation  Account.  If the
     payment  option  described  in paragraph  (i)(b)  above has been  selected,
     payment shall be made in accordance with Section  7.2(iii).  If the payment
     option in paragraph  (i)(c) above has been selected,  payment shall be made
     in accordance  with Section  7.2(iv).  Notwithstanding  the foregoing,  any
     benefits in the Unvested Share Account at the date of a Participant's death
     shall be paid to the  Participant's  Beneficiary or estate, as the case may
     be, in accordance with Section 7.3.

     7.3. Payment Upon Death. Notwithstanding any other provision of the Plan to
the  contrary,  within a  reasonable  period  of time  following  the death of a
Participant,  the amount  credited to the  Participant's  Deferred  Compensation
Account and all of the Share  Equivalents  credited to the  Participant's  Share
Accounts  shall  be  paid  by the  Company  in a lump  sum to the  Participant's
Beneficiary.  For  purposes  of this  Section  7.3,  the amount  credited to the
Participant's  Deferred  Compensation Account, and the number and value of Share
Equivalents credited to the Participant's Share Accounts, shall be determined as
of the date of payment  using the  Average  Closing  Price.  A  Participant  may
designate  a  Beneficiary,  in  writing,  in a form  acceptable  to the Board of
Directors. A Participant may revoke a prior designation of a Beneficiary and may
also  designate  a  new  Beneficiary  without  the  consent  of  the  previously
designated  Beneficiary,   provided,  however,  that  such  revocation  and  new
designation  (if any)  are in  writing,  in a form  acceptable  to the  Board of
Directors, and filed with the Board of Directors before the Participant's death.
If the  Participant  does  not  designate  a  Beneficiary,  or if no  designated
Beneficiary  survives  the  Participant,  any  amount  not  distributed  to  the
Participant  during the  Participant's  life shall be paid to the  Participant's
estate in a lump sum in accordance with this Section 7.3.

     7.4. Payment on Unforeseeable Emergency. The Board of Directors may, in its
sole discretion, direct payment to a Participant of all or of any portion of the
vested portion of a  Participant's  Accounts,  notwithstanding  an election of a
payment option under Section 7.2 above,  at any time that the Board of Directors
determines that such Participant has an unforeseeable  emergency,  and then only
to the extent reasonably  necessary to meet the emergency.  For purposes of this
section,  "unforeseeable  emergency"  means  severe  financial  hardship  to the
Participant  resulting from a sudden and  unexpected  illness or accident of the
Participant  or of a dependent  of the  Participant,  loss of the  Participant's
property due to  casualty,  or other  similar  extraordinary  and  unforeseeable
circumstances  arising  as  a  result  of  events  beyond  the  control  of  the
Participant.

                         SECTION 8. OWNERSHIP OF SHARES

     A  Participant  shall have no rights as a  shareholder  of the Company with
respect to any Shares represented by the Share Equivalents described hereunder.

                     SECTION 9. PROHIBITION AGAINST TRANSFER

     The right of a Participant  to receive  payments  under the Plan may not be
transferred  except by will or applicable  laws of descent and  distribution.  A
Participant may not assign, sell, pledge, or otherwise transfer amounts to which
he/she is entitled hereunder prior to payment thereof to the Participant.

                         SECTION 10. GENERAL PROVISIONS

     10.1. Director's Rights Unsecured.  The Plan is unfunded.  The right of any
Participant  to receive  payments of cash under the provisions of the Plan shall
be an unsecured claim against the general assets of the Company.

     10.2.  Administration.  Except as otherwise  provided in the Plan, the Plan
shall be administered by the Board of Directors,  which shall have the authority
to adopt  rules and  regulations  for  carrying  out the Plan,  and which  shall
interpret,  construe,  and  implement the  provisions of the Plan.  This Plan is
intended to comply with Section 16 of the  Securities  Exchange Act of 1934,  as
amended  (the "Act") and the rules  promulgated  thereunder.  Any  election by a
Participant  which  would be in  violation  of the Act or the  rules  thereunder
causing  short-swing  liability shall be deemed  ineffective under the Plan, and
such election shall be deemed to be null and void.

     10.3.  Legal  Opinions.  The Board of  Directors  may  consult  with  legal
counsel,  who may be counsel for the Company or other  counsel,  with respect to
its  obligations  and duties  under the Plan,  or with  respect  to any  action,
proceeding, or any questions of law, and shall not be liable with respect to any
good faith  action  taken,  or  omitted,  by it  pursuant  to the advice of such
counsel.

     10.4.  Liability.  Any  decision  made or  action  taken  by the  Board  of
Directors,  or any employee of the Company or any of its  subsidiaries,  arising
out of or in connection with the construction,  administration,  interpretation,
or  effect  of the  Plan,  shall  be  absolutely  discretionary,  and  shall  be
conclusive  and binding on all parties.  Neither the Board of Directors  nor any
employee of the Company or any of its  subsidiaries  shall be liable for any act
or action hereunder,  whether of omission or commission,  by any other member or
employee or by any agent to whom duties in connection with the administration of
the Plan have been  delegated or, except in  circumstances  involving bad faith,
for anything done or omitted to be done.

     10.5.  Withholding.  The  Company  shall have the right to deduct  from all
payments  hereunder any taxes required by law to be withheld from such payments.
The  recipients of such payments  shall bear all taxes on amounts paid under the
Plan to the extent that no taxes are withheld  thereon,  irrespective of whether
withholding is required.

     10.6.  Legal  Holidays.  If any day on (or on or before) which action under
the Plan must be taken  falls on a  Saturday,  Sunday,  or legal  holiday,  such
action may be taken on (or on or before) the next  succeeding  day that is not a
Saturday,  Sunday, or legal holiday;  provided,  however, that this Section 10.6
shall not permit any action that must be taken in one calendar  year to be taken
in any subsequent calendar year.

               SECTION 11. AMENDMENT, SUSPENSION, AND TERMINATION

     The  Board of  Directors  shall  have the  right at any  time,  and for any
reason, to amend,  suspend, or terminate the Plan,  provided,  however,  that no
amendment,   suspension,  or  termination  shall  reduce  the  number  of  Share
Equivalents or the cash balance in an Individual Account.

                           SECTION 12. APPLICABLE LAW

     The Plan shall be governed by, and construed in accordance  with,  the laws
of the State of Delaware,  except to the extent that such laws are  preempted by
federal law.

<PAGE>

                           SECTION 13. EFFECTIVE DATE

     The  effective  date of this  Plan is May 1,  1997.  Nothing  herein  shall
invalidate or adversely affect any previous election, designation,  deferral, or
accrual in accordance with the terms of the Prior Plan that were in effect prior
to the effective date of this Plan.

                          SECTION 14. CHANGE IN CONTROL

     Upon the  occurrence  of a Change in Control,  all Accounts  under the Plan
that are not fully vested as of the date of such  occurrence (and which have not
previously   been   forfeited)   will   become   fully   vested.    Furthermore,
notwithstanding any prior election by a Participant to the contrary, at any time
following a Change in Control a Participant  may elect to accelerate  any or all
payments  due under  the Plan to a single  sum  payment  to be made on a date at
least twelve (12) months subsequent to such election;  provided,  however,  that
such an election may be made for an immediate  single sum payment,  in which six
percent  (6%) of the  amount of the  accelerated  payment  shall be  permanently
forfeited to the Company.  For purposes of this  provision,  a Change in Control
will be deemed to have occurred if:

          (i) any person or persons acting in concert (excluding Company benefit
     plans) becomes the beneficial  owner of securities of the Company having at
     least 20% of the voting power of the Company's then outstanding  securities
     (unless the event causing the 20% threshold to be crossed is an acquisition
     of voting common securities directly from the Company); or

          (ii) the  consummation of any merger or other business  combination of
     the Company,  sale or lease of the Company's  assets or  combination of the
     foregoing  transactions  (the  "Transactions")  other  than  a  Transaction
     immediately  following  which the  shareholders  of the  Company  who owned
     shares  immediately  prior to the  Transaction  (including  any  trustee or
     fiduciary  of any Company  employee  benefit  plan) own, by virtue of their
     prior ownership of the Company's  shares, at least 65% of the voting power,
     directly or indirectly, of (a) the surviving corporation in any such merger
     or other business combination; (b) the purchaser or lessee of the Company's
     assets;  or (c) both the surviving  corporation and the purchaser or lessee
     in the event of any combination of Transactions; or

          (iii)  within any 24 month  period,  the  persons  who were  directors
     immediately before the beginning of such period (the "Incumbent Directors")
     shall  cease (for any reason  other than  death) to  constitute  at least a
     majority  of the  Board or the board of  directors  of a  successor  to the
     Company.  For this  purpose,  any  director  who was not a director  at the
     beginning  of such period  shall be deemed to be an  Incumbent  Director if
     such director was elected to the Board by, or on the  recommendation  of or
     with  the  approval  of,  at least  two-thirds  of the  directors  who then
     qualified  as  Incumbent  Directors  (so  long  as  such  director  was not
     nominated  by a person  who has  expressed  an intent to effect a Change in
     Control or engage in a proxy or other control contest).Equity Loan Agreement

Employee Name: Ulf Wiinberg
Loan Amount: $250,000.00                        Dates Issued:    (1) 4/4/02

For value received, the undersigned, Ulf and Gunilla Wiinberg (hereinafter
"Makers"), jointly and severally, promise to pay to Wyeth (hereinafter
"Lender"), or its order, at its designated office or at such other place within
the United States of America that Lender may designate in writing to the
undersigned, the principal sum of Two Hundred and Fifty Thousand Dollars
($250,000.00), payable as follows: (i) $145,000 payable on the date the Makers
sign this Note (the "Downpayment") and (ii) the remainder payable in accordance
with the contract dated March 13, 2002 (the "Contract") between the Makers and
George and Diane Garrison). The principal sum together with interest at the rate
of 2.88% per annum shall be payable in three installments, 25% on March 15,
2003, 25% on March 15, 2004 and 50% on March 15, 2005, provided, however, that
if Mr. Wiinberg's employment with Wyeth terminates for any reason whatsoever
such principal sum together with interest thereon shall be repaid within 90 days
following such date of termination. If the Contract is not consummated, the
Downpayment will be immediately due and payable to the Lender.

In consideration of Lender's entering into this agreement and promissory note
(hereinafter, collectively referred to as this "Note"):

(a)  The Makers represent that the loan will be used solely for the purpose of
     purchasing a new principal residence in connection with a transfer to a new
     principal place of employment and that neither the former nor the new
     principal residence is or will be located outside the United States.
(b)  The Makers represent that the Makers have no intention of converting
     Makers' new principal residence to business or investment use.
(c)  The Makers agree that the obligations and benefits under this Note are
     personal to the Makers and may not be transferred, assigned or otherwise
     disposed of to any person.
(d)  The Makers agree that their new principal residence will not be made
     subject to any further lien, indebtedness or encumbrance by either Makers'
     affirmative act or failure to act subsequent to signing this Note.
(e)  The Makers  hereby  represent  that they intend to and will  itemize  their
     deductions on the Federal Income Tax returns.

This Note shall be subordinate to the primary mortgage entered into by the
Makers upon the closing of the Contract but shall be superior to any other
indebtedness made by the Makers with respect to the property that is the
collateral security for this Note.

This Note may be prepaid in full or in part at any time without premium or
penalty. All prepayments shall be applied first to the payment of any costs of
collection that may be due hereunder, and the balance shall be applied to
principal.

If all or any portion of the indebtedness evidenced hereby is not paid when due
(i) Lender or holder may immediately exercise any right of setoff and enforce
any lien or security interest securing payment hereof and (ii) this Note shall
accrue interest at a rate equal to the lower of seven percent (7%) per annum or
the highest maximum rate permitted by applicable law.

Time is of the essence. No delay or omission on the part of the holder in
exercising any right hereunder shall operate as a waiver of such right or of any
other remedy under this Note. A waiver on any occasion shall not be construed as
a bar to or waiver of any such right or remedy on a future occasion.

The Makers, endorsers, sureties, guarantors and all other persons liable for all
or any part of the indebtedness evidenced by this Note jointly and severally
waive valuation and appraisement, presentment for payment, protest, notice of
protest, dishonor, notice of dishonor, demand, notice of non-payment, and the
benefit of all laws now or hereafter enacted affording any right to a stay of
execution or extension of time for payment or exempting any property of such
person from levy and sale upon execution of any judgment obtained by the holder
under this Note. Such parties hereby consent without affecting their liability
to extension or alteration of the time or terms of payment hereof, any renewal,
any release of any or all part of any security given for the payment hereof, any
acceptance of additional security of any kind, and any release of, or resort to,
any party liable for payment hereof, and such parties shall remain bound in the
same capacities as prior thereto upon each such event.

Makers agree that the obligation to pay all principal and other amounts owing
hereunder is absolute and unconditional under all circumstances. In the event of
any litigation in connection with this Note, Makers waive any right to trial by
jury and agrees not to assert any counterclaim, defense, offset or abatement of
any nature.

Makers and any endorsers and guarantors hereof, and all others who may become
liable for all or any part of this obligation, severally waive Makers agree to
pay the holder hereof all out-of-pocket expenses and costs of collection
including, but not limited to, reasonable attorneys' fees incurred by the holder
hereof in enforcing or attempting to enforce this Note (whether or not a suit is
commenced); and such costs, fees and expenses shall be added to the principal
amount due under this Note.

This Note may not be changed or modified in any way, nor may any provision
hereof be waived, except by a written instrument duly executed by the holder
hereof.

This Note will inure to the benefit of the Lender, its legal representatives,
successors, transferees and assigns. This Note may be transferred and assigned
by Lender at any time.

This Note shall be governed by the laws of the State of New Jersey.
