                          BP DEFERRED COMPENSATION PLAN
                     (As amended and restated effective for
                  deferral elections made after July 31, 2001)



1.   PURPOSE

     The purpose of the BP Deferred Compensation Plan, as amended and restated,
     (the "Plan") is to provide eligible employees of BP Corporation North
     America Inc. (the "Company") and certain of its Affiliates an opportunity
     to defer receipt of Compensation. The Company is a wholly owned, indirect
     subsidiary of BP p.l.c. ("BP").

2.   DEFINITIONS

     (a)  "Administrator" means the Senior Vice President of Human Resources of
          the Company or, upon the resignation or removal of such Senior Vice
          President, any successor officer who performs substantially similar
          duties with respect to the administration of employee benefits
          (whether assigned a different title by the Company or not). The
          Administrator is a "Designated Officer" as such term is defined in the
          Savings Plan and may delegate his duties hereunder.

     (b)  "ADS" means an American Depositary Share of BP, which currently
          represents six ordinary shares of BP.

     (c)  "Affiliate" means any entity that directly or indirectly through one
          or more intermediaries Controls, or is Controlled by, or is under
          common Control with the Company (or with another corporation in the BP
          Group as applicable). Solely for purposes of this Plan, CH-20 will be
          deemed to be an Affiliate.

     (d)  "Base Salary" means the base salary of an eligible employee (as
          defined in Section 3), as adjusted from time to time.

     (e)  "Benchmark Interest Rate" means the rate of interest equivalents
          credited on the balance in a Cash Account. The Benchmark Interest Rate
          is determined, and may be changed, by the Administrator. The prime
          rate on the first day of the month as charged by Bank One, N.A. is the
          current Benchmark Interest Rate.

     (f)  "Beneficiary" means the beneficiary or beneficiaries designated from
          time to time by the Participant to receive his Participant Account in
          the event of his death prior to distribution. A Participant may
          designate, or change the designation of, a Beneficiary under the Plan
          by making the designation in the form and manner and at the time
          determined by the Administrator. No such designation will be effective
          until and unless it is timely received by the Administrator. Unless
          otherwise designated on the Participant's beneficiary designation
          form, if the Participant designated more than one Beneficiary and if a
          Beneficiary predeceases the Participant, then all amounts which would
          have been paid to such deceased Beneficiary on the Participant's death
          will be paid in equal amounts to any remaining Beneficiaries in that
          class of Beneficiaries. If the Participant dies without having filed a
          valid Beneficiary designation, his Beneficiary will be his surviving
          spouse, or if none, his estate.

          Compensation is awarded or Base Salary is deferred.

     (l)  "Company"  means BP Corporation  North America Inc. The Company is the

          50% of the equity of a corporation, or more than 50% of the ownership
          interests in a non-corporate entity, or the ability through share
          ownership or otherwise to elect a majority of the board of directors
          of a corporation.

     (o)  "Dividend Equivalent" means the amount which is the equivalent to the
          net dividend paid on an ADS which amount is credited to a
          Participant's Phantom ADS Account on the dividend payment date for
          ADSs.

     (p)  "Fair Market Value" means, as of any specified date, the average of
          the highest and lowest quoted selling prices of ADSs as reported on
          the composite tape for issues listed on the New York Stock Exchange on

          date, the average of the highest- and lowest-quoted selling prices of
          ADSs on the most recent date prior to the specified date on which
          sales of ADSs were so reported.

          Section 3) means:

          (2) a sign-on bonus; (3) a retention bonus; or; (4) a comparable
          arrangement, as determined by the Administrator.

     (r) "Investment Option" means:

          (1) Until  December 31,  2001:
               (A)  for a Participant's 1999 Account "Investment Option" means
                    the choice between: (i) a Phantom ADS Account with Dividend
                    Equivalents, or (ii) a Cash Account with interest
                    equivalents at the Benchmark Interest Rate (with all or a
                    portion of the Cash Account or Phantom ADS Account converted

                    once every three calendar months); and

               (B)  for a Participant's 2000 Account "Investment Option" means a
                    Cash Account with interest equivalents at the Benchmark
                    Interest Rate.

          (2)  Effective January 1, 2002, "Investment Option" means the
               hypothetical equivalent of each investment option under the
               Savings Plan. To the extent appropriate for the hypothetical
               Investment Options available under this Plan (determined in the
               sole discretion of the Administrator), the Administrator will
               apply the same values, rules, and procedures used by the plan
               administrator of the Savings Plan in determining hypothetical
               gains and losses for Investment Options under this Plan.
               Transactions and hypothetical investments under this Plan will be
               processed using the same time frames as apply in the Savings
               Plan. The Administrator will apply any transitional rules
               approved in the Savings Plan to this Plan where investment
               options are frozen, added or dropped, or where daily values are
               not available. Notwithstanding the foregoing, to the extent
               maintained as a Cash Account as of December 31, 2001, a
               Participant's 1999 or 2000 Account may remain in a Cash Account;
               provided, however, that no hypothetical exchanges may be made
               into a Cash Account after December 31, 2001.

     (s)  "1999 Account", or "2000 Account" means an account maintained with
          respect to a Participant's 1999 or 2000 Incentive Compensation
          deferred under this Plan and awarded in 2000 and/or 2001,
          respectively.

     (t)  "Participant" means an eligible employee (as provided in Section 3)
          who has elected, under the terms and conditions of the Plan, to defer
          receipt of all or a portion of his Compensation. An individual will
          cease being a Participant as of the date his entire Participant
          Account has been distributed.

     (u)  "Participant Account" means an unfunded account maintained on behalf
          of a Participant by the Administrator to reflect all Compensation
          deferred by the Participant under this Plan and any hypothetical gains
          or losses relating to such deferrals.

     (v)  "Participating Employer" means the Company and any of its Affiliates
          which have been determined in writing by the Administrator to be a
          Participating Employer. Effective January 1, 2002, in order to be a
          Participating Employer, an Affiliate must use the same payroll system
          as the Company, except to the extent otherwise provided by the
          Administrator.

     (w)  "Phantom ADS Account" means the account for the Investment Option
          which is Phantom ADS Units established under a Participant's 1999
          Account. In the event that ADSs (or any successor equity) cease
          trading on the New York Stock Exchange ("NYSE"), the Fair Market Value
          of each Participant's Phantom ADS Account will automatically be
          converted to the Participant's Cash Account. Effective as of the close
          of business on the NYSE on December 31, 2001, each Participant's
          Phantom ADS Account will automatically be converted to the
          hypothetical BP Stock Fund Investment Option by valuing the Phantom
          ADSs in the Participant's Account at the closing price of the NYSE
          used for the valuation of ADSs in the Savings Plan's BP Stock Fund and
          by dividing the resulting Phantom ADS Account value by the December
          31, 2001 unit price to yield the number of units of the hypothetical
          BP Stock Fund in the Participant's Account at conversion.

     (x)  "Phantom ADS Unit" means, on or before December 31, 2001, the
          equivalent of an ADS in corresponding value which is credited to a
          Participant's Phantom ADS Account.

     (y)  "Savings Plan" means the BP Employee Savings Plan, as amended, and any
          successor plan.

     (z) "Service Period" means:

          (1)  for purposes of deferring an award under an eligible incentive
               plan, the eligible employee must remain employed by the BP Group
               through the last business day of the calendar year in which the
               award was earned;
          (2)  for purposes of deferring a retention bonus, the eligible
               employee must remain employed by the BP Group through the last
               day of the retention period; or
          (3)  other periods, as determined by the Administrator.

     (aa) "Termination" means an employee's termination of employment from the
          BP Group for any reason other than death.

     (bb) "Timely Election" means:

          (1)  for purposes of deferring an award under an eligible incentive
               plan, an election made during the annual election period as
               determined by the Administrator; provided, however, that the
               deferral will not be considered as timely if the award is payable
               in the calendar year in which the deferral election is made;
          (2)  for purposes of deferring Base Salary on initial eligibility, an
               election made during the initial 45 day period following the date
               of initial eligibility;
          (3)  for purposes of deferring Base Salary after initial eligibility,
               an election made by the last business day of the calendar year
               for salary deferral commencing during the following calendar
               year;
          (4)  for purposes of deferring  sign-on  bonuses,  an election made by
               the first day worked for the  Company  or an  Affiliate;
          (5)  for purposes of deferring a retention bonus, an election made
               within 30 days of the start of the retention period, provided
               however, that the election must be on file no later than 60 days
               prior to the end of the retention bonus Service Period; or
          (6)  other elections, as determined by the Administrator.

3.   ELIGIBILITY

     The following classes of employees are eligible to participate in the Plan:

     (a)  An  employee  of a  Participating  Employer  on  a  U.S.  payroll  who
          participates in a U.S. qualified pension plan sponsored by the Company
          who is in grade F or  higher  (or an  equivalent  grade  if the  grade
          system is changed or different terminology is used); or

     (b)  Any other  employee  of the BP Group as  determined  in writing by the
          Administrator.


     Notwithstanding the foregoing, eligibility will be determined at the time
     the election is solicited, at the sole discretion of the Administrator.



4.   TERMS OF DEFERRAL ELECTIONS

     (a)  An eligible employee must make a Timely Election if he wishes to defer
          receipt of Compensation.

     (b)  An eligible employee may elect to defer:

          (1)  all  or  a  portion  of  Incentive  Compensation  (in  1  percent
               increments; and
          (2)  up to 50 percent  of Base  Salary in  increments  of 1 percent as
               determined for each payroll period during the period of deferral.

          The  Administrator   reserves  the  right  to  unilaterally  reduce  a
          Participant's  deferral  election in order to satisfy  other  required
          payroll deductions, or otherwise.

     (c)  A Timely  Election  to defer  Compensation  will be  considered  to be
          received if it is made in accordance  with  procedures  established by
          the  Administrator.  Except as otherwise  stated herein,  elections to
          defer become irrevocable at the end of the applicable  election period
          for Timely Elections.

     (d)  Notwithstanding   the  foregoing,   no  election  to  defer  Incentive
          Compensation  will be effective  unless the eligible  employee remains
          employed by the BP Group  through the last business day of the Service
          Period during which the Incentive Compensation was earned.

     (e)  Deferrals of Base Salary are effective through December 31 annually. A
          Deferral of Base Salary election will end earlier on the Participant's
          death,  Termination  or  transfer  to  an  Affiliate  that  is  not  a
          Participating  Employer.   Further,  during  the  deferral  period,  a
          Participant  can elect to rescind  prospectively  (but not increase or
          decrease) his Base Salary deferral election;  provided,  however, that
          he will not be considered an eligible employee under this Plan for the
          remainder of the calendar year and for the following calendar year and
          such rescission  will  invalidate any other pending  election to defer
          Incentive Compensation under the Plan.

     (f)  Deferred  Compensation  will be adjusted  for  hypothetical  earnings,
          gains or losses based on  hypothetical  investment in accordance  with
          Participant's   Investment   Option   elections   on  file   with  the
          Administrator.  In the event that either no Investment Option has been
          elected  as an  investment  election,  or that an  elected  Investment
          Option is no longer available,  the default  Investment Option will be
          the Investment Option  equivalent to the default  investment option in
          the Savings Plan at that time.

     (g)  At the time of the deferral election, the eligible employee must elect
          to have deferral distributions commence either: (1) in a specific year
          --  even  if  the  Participant  is  then  employed  by  the  BP  Group
          ("In-Service  Deferral"),  or  (2)  after  Termination  ("Post-Service
          Deferral").

     (h)  For each  separate  element of  Compensation  deferred  during a Class
          Year, the eligible  employee must elect either an In-Service  Deferral
          or a Post-Service  Deferral.  Compensation  deferred with respect to a
          separate  element of Compensation  deferred during a particular  Class
          Year may not be allocated among In-Service  Deferrals and Post-Service
          Deferrals.

     (i)  In-Service Deferrals, including the distribution schedule elected, are
          irrevocable when made, notwithstanding Termination before commencement
          of  scheduled  distributions;  provided,  however,  that  as  soon  as
          administratively  practicable  (as  determined by the  Administrator),
          In-Service  Deferrals  will  automatically   convert  to  Post-Service
          Deferrals on the earlier of a Participant's  Termination or death, and
          further provided,  that this provision will only apply if the eligible
          employee has notice of this condition at the time of deferral.

     (j)  Notwithstanding  Section 4(i), a Participant,  may exercise a one-time
          election  to  convert  an  In-Service   Deferral  with  respect  to  a
          particular  Class Year to a  Post-Service  Deferral if the election to
          convert is made (in accordance with the Administrator's  requirements)
          at least  one year  prior to the  earliest  date  that the  In-Service
          Deferral for the Class Year would have been payable.

     (k)  An election to make a Post-Service Deferral becomes irrevocable at the
          end  of  the  election  period  for  Timely  Elections;  however,  the
          distribution schedule may be modified consistent with the Plan's terms
          if a timely  request  to  change is  effectuated  in  accordance  with
          Section 4(n).

     (l)  Payout of deferred Compensation may be as follows:

          (1)  In an  In-Service  Deferral:  (A) in a lump sum or (B) in up to 5
               annual installments, provided that all payments must be completed
               by April 1 of the 15th calendar year beginning after the deferral
               date; or

          (2)  In a Post-Service  Deferral: (A) in a lump sum or (B) in up to 15
               annual, 60 quarterly, or 180 monthly installments,  provided that
               all payments  must be  completed by April 1 of the 15th  calendar
               year beginning after Termination.  If a Post-Service  Deferral is
               elected  without  the  election  of  a  permissible  distribution
               schedule,  payment  will  be  made  in a  lump  sum  as  soon  as
               administratively  practicable after the first day of the calendar
               quarter 18 months  following  the  Participant's  Termination  or
               death.

     (m)  Notwithstanding Subsection (l) above:

          (1)  In  the  event  of  a  Participant's   death,  the  Participant's
               Beneficiary  will be deemed to be the Participant for purposes of
               determining  when the  Participant's  Account will be distributed
               and, with regard to a Participant who dies during employment with
               the BP Group,  the  Participant's  death will be deemed to be his
               Termination for purposes of triggering any Post-Service  Deferral
               election  on  file;  provided,  however,  that  any  distribution
               payable to the Participant's estate will be made in a lump sum as
               soon as practicable  following the  Participant's  death.  To the
               extent  that  a   Beneficiary   has  a  right  to  maintain   the
               Participant's  Account,  the Beneficiary will be deemed to be the
               Participant  for purposes of making  exchanges  among  Investment
               Options.

          (2)  At the sole discretion of the Administrator,  if the balance in a
               Participant's  Participant  Account does not exceed $25,000 after
               the earlier of his Termination date or his death, the balance may
               be  mandatorily  paid  out in a lump  sum as soon  as  reasonably
               practicable, notwithstanding any distribution schedule elected by
               the Participant.

          (3)  A Participant or Beneficiary  may request  acceleration of payout
               of all or a portion  of the  Participant's  Account  to a date or
               dates  sooner than  elected in the case of  unanticipated  severe
               financial  hardship  beyond  the  control of the  Participant  or
               Beneficiary.  Such payment will be made at the sole discretion of
               the Administrator. Any such accelerated payout will be limited to
               the amount deemed necessary by the  Administrator to alleviate or
               remedy the Participant's or Beneficiary's financial hardship.

          (4)  Notwithstanding  (m)(3) above, a Participant  or Beneficiary  may
               request  acceleration  of  payment  of  all or a  portion  of the
               Participant  Account  to a date or  dates  sooner  than  elected,
               without  regard to any hardship  need,  upon the  imposition of a
               forfeiture of 20 percent of the amount to be  distributed  early.
               Such  request  must  be  made  in  accordance   with   procedures
               established  by the  Administrator.  The  Administrator  has sole
               discretionary authority to grant or deny any such requests.

     (n)  A  Participant  who has elected a  Post-Service  Deferral  pursuant to
          Section  4(l)(2) may (in accordance  with any  procedures  that may be
          established by the Administrator) request that the Administrator alter
          the distribution schedule previously established for the Participant's
          Participant Account,  provided that: (1) any such request must be made
          no later than 12 months prior to the date when any distribution  could
          have  commenced  under the prior  distribution  election  (or  default
          distribution  date in Section 4(l) in the event no valid  Post-Service
          Deferral  election  was timely  received),  and (2) if such request is
          granted,  the  first  distribution  to be made  under a  Participant's
          distribution  schedule may be made no sooner than 12 months after such
          changed Post-Service  Deferral distribution schedule is filed with the
          Administrator.  Further,  an  otherwise  valid  Post-Service  Deferral
          election will become invalid if the participant  subsequently incurs a
          Termination  and the requested  distribution  election is scheduled to
          commence within 12 months of when the Post-Service  Deferral  election
          form was filed.

     (o)  Payouts of Participant Accounts will be made only in cash by check (or
          by other method approved by the Administrator) and will not be made by
          payment in ADSs or other securities.

     (p)  The  most  recent  distribution  schedule  election  accepted  by  the
          Administrator  from  a  Participant  with  respect  to a  Post-Service
          Deferral  will  apply to all  Post-Service  Deferrals  elected  by the
          Participant  under  this  Plan  without  regard  to  the  elements  of
          Compensation so deferred.

5.   PARTICIPANT ACCOUNTS

     (a)  In General

          The   Administrator   will   maintain   records   which  reflect  each
          Participant's  deferrals,  hypothetical  gains and losses  applying to
          such  deferrals  based  on  the  applicable   Investment  Options  and
          distributions  made from the Account.  The Administrator will maintain
          separate  subaccounts  under a  Participant  Account as he  determines
          appropriate for proper administration,  including,  but not limited to
          In-Service  Deferrals,  Post-Service  Deferrals,  Investment  Options,
          elements of Compensation  deferred with respect to a particular  Class
          Year,  1999  Accounts and 2000  Accounts.

     (b)  Special Rules for 1999 Accounts and 2000 Accounts

          (1)  Interest  Equivalents  on  Cash  Accounts

               A  Participant's  Cash  Account  will be credited  with  interest
               equivalents  and  compounded  monthly at the  Benchmark  Interest
               Rate.

          (2)  Phantom ADS Account/Dividend Equivalent

               The value of  Phantom  ADS  Units for  purposes  of  crediting  a
               Participant  Account  with  periodic  Dividend   Equivalents  and
               reinvesting  such amounts in additional  Phantom ADS Units is the
               Fair  Market  Value of ADSs on the  applicable  dividend  payment
               date. Any Phantom ADS Units will be maintained in the Participant
               Account. The number of Phantom ADS Units in a Phantom ADS Account
               will be adjusted  to give  effect to any  increase or decrease in
               the number of issued and outstanding ADSs through the declaration
               of a stock dividend or through  recapitalization  resulting in an
               ADS or ordinary share split,  combination or exchange of ordinary
               shares or the like.  Phantom  ADS Units do not entitle any person
               to the rights of a holder of ADSs or ordinary shares of BP.

          (3)  Conversion of 1999  Participant  Account Prior to January 1, 2002

               Prior to January 1, 2002, a Participant with a 1999 Account,  may
               request  conversion  of all or a portion of his Cash  Account (to
               his Phantom  ADS  Account) or all or a portion of his Phantom ADS
               Account  (to  his  Cash  Account).  Subject  to  approval  by the
               Administrator,  a conversion  requested  will be effective on the
               date the request is allocated by the Administrator.

          (4)  Conversion   of   Cash   Account   After    December   31,   2001

               After  December 31, 2001, a  Participant  with a Cash Account may
               direct the  Administrator to convert all or a portion of his Cash
               Account to one or more Investment  Options in accordance with the
               applicable conversion procedures established by the Administrator
               from time to time.  No  conversions  may be directed  into a Cash
               Account after December 31, 2001.

6.   PAYMENT OF DEFERRED COMPENSATION

     (a)  Except  as  provided  in  Section  4(m)(4)  and in  Section  12,  each
          Participant  is  entitled  to  receive  the  value of his  Participant
          Account at the date of distribution  (less taxes, if any,  required to
          be withheld by the federal or any state or local  government  and paid
          over to such  government for the  Participant) in accordance with such
          Participant's election(s).

     (b)  If installments are elected, the amount of the first payment will be a
          fraction  of the  balance  in the  Participant  Account  as of the day
          preceding  each  payment,  the  numerator  of  which  is one  and  the
          denominator of which is the total number of installments elected minus
          the number of installments previously paid.

7.   UNFUNDED OBLIGATION OF BP

     Obligations to make payments to Participants under this Plan are unsecured,
     general obligations of BP.  Notwithstanding  the foregoing,  payments under
     this Plan may be made from the general  funds of  Participating  Employers,
     BP, or any affiliate of BP. No special or separate fund will be established
     and no other  segregation  of assets  will be made to assure the payment of
     any deferrals or earnings  thereon.  Nothing  contained in this Plan and no
     action taken pursuant to its provisions,  creates or should be construed to
     create a trust or escrow of any kind or a fiduciary relationship between BP
     or any of its Affiliates and any other person.  To the extent a Participant
     or any other  person has a right to receive  payments  under this Plan such
     right   ranks  parri  passu  with  other   unsecured   and   unsubordinated
     indebtedness of BP.

8.   NON-ASSIGNABILITY

     The right of a Participant to receive any unpaid portion of the Participant
     Account may not be  voluntarily  or  involuntarily  assigned,  transferred,
     pledged  or  encumbered  or be  subject  in any  manner  to  alienation  or
     anticipation, except as provided in Section 12.

9.   ADMINISTRATION

     The  Administrator  has the sole  discretionary  authority  to adopt rules,
     regulations  and  procedures  for carrying out this Plan,  to interpret and
     implement its provisions and to grant or deny any and all claims hereunder.
     The  Administrator  may  correct  any  defect or  supply  any  omission  or
     reconcile any  inconsistency in the Plan in the manner and to the extent he
     deems expedient to carry it into effect. The Administrator's determinations
     are final and binding on all  persons.  The  Administrator  may delegate to
     other persons the responsibility of performing  operational and ministerial
     acts in furtherance of the Plan's purposes,  but only the Administrator may
     act on any aspect of the Plan  affecting (a) any officer or director of the
     Company who is an  employee of the Company or (b) any  employee to whom the
     Administrator  delegates authority with respect to the Plan.  However,  any
     action  that would  otherwise  result in  self-approval  on the part of the
     Administrator with regard to participation in the Plan requires approval by
     the Board of Directors.  Subject to Section 10, the  determinations  of the
     Administrator with regard to all Plan matters are final and conclusive.

10.  AMENDMENT AND TERMINATION

     This Plan may at any time be amended by the Administrator or any officer of
     the Company or BP Group designated by the Board of Directors as having such
     authority,  subject to such  restrictions  and conditions on such rights as
     the Board of Directors  may impose.  The Plan may at any time be amended or
     terminated  by the Board of Directors  or BP. No  amendment or  termination
     will,  without  the  consent  of  a  Participant,   adversely  affect  such
     Participant's  rights with respect to amounts  credited to his  Participant
     Account on the effective date of such amendment or termination.

11.  NO EMPLOYMENT RIGHTS CONFERRED

     Nothing  contained in the Plan (a) confers upon any employee any right with
     respect to continuation of employment  with any  Participating  Employer or
     the BP Group, (b) interferes in any way with the right of any Participating
     Employer to terminate any employee's employment at any time, or (c) confers
     upon any  employee or other  person any claim or right to any  distribution
     under the Plan except in accordance with its terms.

12.  WITHHOLDING/RIGHT OF OFFSET

     All accounts,  payments or distributions  under the Plan are subject to all
     such income and  employment  taxes as are required,  in the judgment of the
     Participating  Employer,  to be  withheld,  deducted,  or collected by such
     Participating Employer under applicable federal, state, local or other laws
     then in effect. Such taxes may also include  hypothetical taxes and related
     amounts  under the BP Group's tax  policies  (as amended from time to time)
     for expatriates and secondees.  The Participating  Employer may collect any
     debt,  obligation,  tax  or  liability  owed  by  the  Participant  to  the
     Participating  Employer,  as  determined  in the  sole  discretion  of such
     Participating Employer, by any of the following means:

     (a)  withholding from payroll;

     (b)  collecting payment by check;

     (c)  deducting from the person's Participant Account; or

     (d)  deducting  from  the  net  proceeds  payable  to  a  Participant,  his
          Beneficiary, or his Personal Representative.

13.  OTHER DEFERRED COMPENSATION PLANS

     Other  deferred  compensation  plans of the Company will continue in effect
     until  such  time as they may be  terminated  by the  Board  of  Directors;
     provided,  that (a) no further amount may be deferred  pursuant to any such
     plan after so  determined  in writing  by the Board of  Directors,  (b) the
     Board of  Directors  may provide that any amounts  deferred  under any such
     plan may be credited to Participant  Accounts under the Plan subject to the
     provisions of such other plan, and (c) the Board of Directors may determine
     such other  conditions as it may deem  appropriate to effect the transition
     from such plans to the Plan.

     are used herein in the masculine gender, they are to be construed as though
     they were also used in the feminine  gender,  and vice versa;  wherever any
