The  following  are sets of Questions and Answers that were first posted on
Burlington  Resources  Inc.'s  intranet web site on the evening of March 7,
2006.

                         FREQUENTLY ASKED QUESTIONS

These  questions  and  answers  have been  written to provide  you with the
information  requested in employee  meetings  and on the Employee  Resource
Site.  Employee  questions that are similar in nature are grouped together,
rephrased  and answered by a team from Human  Resources.  Please note: If a
conflict is discovered between these Q&As and the Plan Documents,  the Plan
Documents  will  prevail.  For  specific  individual  questions,   you  are
encouraged to seek assistance from your Human Resources  representative for
answers related to your personal circumstances.

CHANGE IN CONTROL / SEVERANCE

Q:   DOES THE EMPLOYEE  CHANGE IN CONTROL  SEVERANCE  PLAN TAKE EFFECT ONLY
     UPON THE  MERGER,  OR DOES IT ALSO  COVER  THOSE WHO MIGHT BE  SEVERED
     BEFORE THE MERGER?

A:   The plan  generally  takes  effect  upon the actual  change in control
     which will occur on the date the merger is completed,  which we expect
     to  occur on  March  31.  The plan  also  protects  employees  who are
     terminated  before then, if they are terminated in anticipation of the
     merger.  However,  BR does not  expect to conduct  any  merger-related
     layoffs prior to the merger closing date.

Q:   FOR HOW LONG WILL THE EMPLOYEE CHANGE IN CONTROL  SEVERANCE PLAN BE IN
     PLACE?

A:   The Employee  Change in Control  Severance Plan will cover  triggering
     events that occur within a 24-month  period  following  the  Effective
     Time  of  the  merger,  which  is  expected  to be  March  31.  So the
     protection period would expire on March 31, 2008.

Q:   IF I AM ASKED TO WORK IN A TRANSITION  ROLE, AM I REQUIRED TO DO SO TO
     REMAIN ELIGIBLE FOR SEVERANCE?

A:   If you are asked to continue in a transition role in the same location
     and  there  is  not  a  substantial   reduction  in  the  position  or
     responsibilities  you  had  before  the  merger,  then  you may not be
     eligible  for  severance  until  such time as the  transition  role is
     completed  and your  employment is severed by  ConocoPhillips.  If you
     voluntarily  terminate your employment,  unless such decision is based
     on "Good  Reason" as that term is  defined  in the Plan,  you may lose
     eligibility for severance benefits under the Burlington Resources Inc.
     Employee Change In Control Severance Plan.

Q:   IF I ACCEPT A JOB WITH  CONOCOPHILLIPS  AND A YEAR LATER I AM ASKED TO
     TRANSFER TO A DIFFERENT POSITION OR LOCATION, WHAT ARE MY CHOICES?

A:   If you accept a position with  ConocoPhillips  and one year later were
     offered  a  transfer  to  a  different  position  with  a  substantial
     reduction in position or responsibilities or a transfer to a different
     location  greater  than 35 miles,  then you could  either  accept  the
     position or decline the position.  If you declined the  position,  you
     would only be eligible for severance  benefits if your employment were
     terminated  by  ConocoPhillips.   A  unilateral  decision  by  you  to
     terminate  your  employment  without  the  mutual  written  consent of
     ConocoPhillips  may  result  in  loss  of  eligibility  for  severance
     benefits  under  the  Burlington  Resources  Inc.  Employee  Change In
     Control Severance Plan, unless such decision is based on "Good Reason"
     as that term is defined in the Plan.

Q:   I AM AN EXPAT  AND WILL BE  REPATRIATED  IN TO MY HOME  BASE  SOMETIME
     DURING THE NEXT TWO YEARS.  IF I AM OFFERED A COP  POSITION  NOW WHICH
     WOULD REQUIRE ME TO RELOCATE TO MY HOME BASE CITY (BUT WITHIN 35 MILES
     OF BR'S  CURRENT  OFFICE  LOCATION IN MY HOME BASE CITY),  WILL I HAVE
     GOOD REASON UNDER THE EMPLOYEE  CHANGE IN CONTROL  SEVERANCE PLAN IF I
     CHOOSE NOT TO ACCEPT THAT POSITION?

A:   Unless  there is other cause for Good Reason  under the CIC  Severance
     Plan,  we do not  believe  your  repatriation  will  give rise to Good
     Reason. Your expat position is a temporary work assignment and you are
     being  returned  to your  home  base,  within  35 miles  of your  work
     location in the home base city. We do not believe  that,  for purposes
     of the Employee CIC Severance  Plan,  that situation would satisfy the
     35 mile relocation trigger in the "Good Reason" definition.

Q:   PLEASE  EXPLAIN  WHY AN  EMPLOYEE  WHO  DOES  NOT  WISH  TO  WORK  FOR
     CONOCOPHILLIPS WILL NOT BE ALLOWED TO VOLUNTEER FOR SEVERANCE?

A:   The  Employee  Change in  Control  Severance  Plan is meant to provide
     protection  where  employment is terminated as a result of the merger,
     either by the  Company  without  cause or by the  employee  if changes
     occur in their job that would constitute Good Reason. The plan was not
     intended to provide a general  benefit simply because of the change in
     control.   There  would  be  no  need  for  severance   protection  if
     ConocoPhillips has a business need to continue your employment and the
     position was substantially  similar to the position you had before the
     merger.

COMPENSATION PROGRAMS
---------------------

Q:   WHAT HAPPENS TO MY STOCK OPTIONS AFTER THE MERGER DATE?

A:   All BR  stock  options  will  convert  to  COP  stock  options  at the
     Effective  Time  of the  merger.  The  effect  of the  merger  on your
     particular  stock  options  depends  on when the  stock  options  were
     granted, under which plan (i.e., 1993 Stock Incentive Plan, 1997 Stock
     Incentive Plan or 2002 Stock Incentive Plan) the options were granted,
     and your employment status with ConocoPhillips.

     Vesting and conversion of stock options:
     ----------------------------------------

     o    If your  stock  options  were  granted  prior  to the date of the
          Merger  Agreement,  the options will vest at the "Effective Time"
          of the merger  which is  expected  to occur on March 31. In order
          for you to calculate the effect, a sample  calculation  worksheet
          is  provided  on the  Employee  Resource  site  under  the  Human
          Resources   Updates  heading  in  the  Company-Wide   Information
          section.

     o    If your stock options were granted after December 12, 2005, those
          options will not  automatically  vest at the Effective Time. They
          will  vest  on the  normal  schedule  or  sooner  if,  after  the
          Effective Time of the merger,  your  employment is  involuntarily
          terminated  by BR or COP without Cause or by you for Good Reason.
          At the Effective  Time of the merger,  these options will convert
          entirely  into  options  of COP.  You  will  receive  an  updated
          schedule showing your adjusted number of options in April.

     Stock option exercise period:
     -----------------------------

     o    If you are  involuntarily  terminated  and  receive  a Change  in
          Control severance benefit the following applies.

          o    If your  stock  options  were  granted  under the 1993 Stock
               Incentive  Plan and/or 2002 Stock  Incentive  Plan, you will
               have the lesser of three  years or the life of the option to
               exercise your options following your date of termination.

          o    If your  stock  options  were  granted  under the 1997 Stock
               Incentive  Plan , you will  have the  lesser of 12 months or
               the life of the option to  exercise  your  option  following
               your date of termination.

     o    If you continue your  employment  with  ConocoPhillips  the stock
          options may be exercised  according to the terms under which they
          were granted.

Q:   WHAT HAPPENS TO MY RESTRICTED STOCK AFTER THE MERGER DATE?

A:   The  effect of the  merger on  restricted  stock  depends  on when the
     restricted   stock  was  granted  and  your  employment   status  with
     ConocoPhillips.

     o    If your  restricted  shares were granted prior to the date of the
          Merger Agreement  (December 12, 2005),  these shares will vest at
          the "Effective  Time" of the merger which is expected to occur on
          March  31.  Each  of  these   shares  will   receive  the  merger
          consideration  of  $46.50  plus  0.7214  share of  ConocoPhillips
          stock.  In  order  for you to  calculate  the  effect,  a  sample
          calculation  worksheet is provided on the Employee  Resource site
          under the Human  Resources  Updates  heading in the  Company-Wide
          Information section.

     o    If your  restricted  shares were granted after December 12, 2005,
          those shares will not  automatically  vest at the Effective Time.
          They will vest on the normal  schedule  or sooner  if,  after the
          Effective Time of the merger,  your  employment is  involuntarily
          terminated  by BR or COP without Cause or by you for Good Reason.
          At the  Effective  Time of the merger,  these shares will convert
          entirely into shares of COP. You will receive an updated schedule
          showing your adjusted number of restricted shares in April.

Q:   WHAT HAPPENS TO MY RESTRICTED STOCK AND STOCK OPTIONS IF I VOLUNTARILY
     RESIGN OR AM TERMINATED FOR CAUSE?

A:   In the  instance  that an employee  either  voluntarily  resigns or is
     terminated for cause,  the treatment of options and  restricted  stock
     would be governed by the provisions of the respective  Stock Incentive
     Plan (1993,  1997,  or 2002).  Please  consult the Plan  documents you
     received with your grant for details.

Q:   WHAT DOES  "EXCELLENT"  LEVEL OF PERFORMANCE MEAN IN TERMS OF THE 2006
     BR BONUS PAYMENT?

A:   Payment at the  "excellent"  level of performance  means that you will
     receive 100% for the Company and Division components of your bonus and
     will also receive 100% for your individual component of the bonus. For
     example,  if your bonus  target is 9%, you will  receive  4.5% for the
     company/division  component and 4.5% for your individual component for
     a total of 9%.  In most  cases  however,  it is  anticipated  that the
     highest of the three most recent bonuses paid will be the bonus amount
     paid to employees within thirty days of close.

Q:   WILL THE POST CLOSE BONUS TO BE PAID IN ACCORDANCE  WITH THE INCENTIVE
     COMPENSATION PLAN WILL BE BENEFIT BEARING?

A:   For US  employees,  this bonus  payment  will be benefit  bearing with
     regard to the US Pension  Plan and to the Savings  Plan  provided  the
     employee has elected a deferral under the Plan.

     For  Canadian  employees,  the bonus  payment will be benefit  bearing
     with regard to the CHEL DB Plan.

BENEFIT PROGRAMS
----------------

Q:   DOES COP HAVE A STANDARD RELOCATION POLICY?

A:   Yes. The program includes items such as expense reimbursement,  travel
     allowances,  home purchase and sale assistance and moving expenses. An
     employee  who receives an offer which  requires a  relocation  will be
     provided with a copy of the policy at the time the offer is made.

Q:   WILL THE  BENEFITS  PROVIDED  TO  TERMINATED  EMPLOYEES  FOR 18 MONTHS
     FOLLOWING THEIR TERMINATION BE THE SAME BENEFITS THAT WE HAVE NOW?

A:   Section  4.2(c) of the  Employee  Change  in  Control  Severance  Plan
     states,  the medical,  dental,  vision,  pharmacy  and life  insurance
     benefits  provided to  terminated  employees  for 18 months  following
     their  termination  will be "no less  favorable"  in terms of amounts,
     deductibles  and costs in the  aggregate.  ConocoPhillips  intends  to
     provide the same  benefits  under the BR plan for a limited  period of
     time and will then convert employees over to  ConocoPhillips  benefits
     plans which are deemed to be equivalent to those provided by BR.

Q:   UNDER THE EMPLOYEE  CHANGE IN CONTROL  SEVERANCE PLAN, BR WILL PROVIDE
     BENEFITS FOR 18 MONTHS FOLLOWING AN EMPLOYEE'S  TERMINATION  DATE. ARE
     U.S.  EMPLOYEES  THEN  ELIGIBLE  FOR 18 MORE MONTHS OF COVERAGE  UNDER
     COBRA LAW?

A:   No. COP's  practice is that the 18 months of continued  coverage  that
     will be provided under the Change in Control plan to eligible  severed
     U.S. employees  satisfies the COBRA requirements under the Alternative
     Coverage rules.

Q:   CAN  EMPLOYEES  WHO ARE  TERMINATED  DUE TO THE CHANGE IN CONTROL MAKE
     CHANGES  IN THEIR  BENEFIT  ELECTIONS  FOR THE 18 MONTHS  OF  EXTENDED
     COVERAGE?

A:   Only if a qualified  family  status change  occurs,  such as marriage,
     divorce, the birth of children, etc., changes to the benefit elections
     could be made.  Definitions of these status changes are in the summary
     plan description posted on the BR intranet on the Employee  Info/Human
     Resources/Corporate Benefits pages.

Q:   WILL U.S. BR EMPLOYEES BE REQUIRED TO CLOSE THEIR BR U.S. SAVINGS PLAN
     ACCOUNTS AFTER THE CHANGE IN CONTROL?

A:   No. The change in control  itself  will not trigger any changes in the
     BR U.S. Savings Plan. However,  employees who are terminated will have
     the option of leaving  their  balance in the plan,  rolling over their
     balance  into  another  qualified  IRA  plan,  or  taking  a  lump-sum
     distribution (which might be taxable).

Q:   WILL THE  AMOUNT OF MY  VACATION  CHANGE IF I BECOME A  CONOCOPHILLIPS
     EMPLOYEE?

A:   Your vacation will not change. If you have 3 weeks of vacation with BR
     your service for vacation  purposes  will be  recognized  and you will
     have three weeks of vacation with  ConocoPhillips.  You can learn more
     about ConocoPhillips' vacation policy at one of the upcoming town hall
     or small group meetings.

RETIREMENT / PENSION
--------------------

Q:   IF AN EMPLOYEE IS TERMINATED AND HE OR SHE IS ELIGIBLE TO RETIRE,  CAN
     HE  OR  SHE  RECEIVE  THE  SEVERANCE  PAYMENT,  THE  PENSION  LUMP-SUM
     DISTRIBUTION AND THE 18 MONTHS OF MEDICAL INSURANCE?

A:   If an employee is terminated  and is eligible for  severance  benefits
     under the Employee  Change in Control  Severance  Plan,  the resulting
     severance   payment  would  not  impact   eligibility  for  retirement
     benefits,   provided   that  the   employee   meets  the   eligibility
     requirements for the particular pension plan involved.

EMPLOYMENT
----------

Q:   HOW  WILL   FUTURE  BR   EMPLOYMENT   VERIFICATION   BY   HANDLED   BY
     CONOCOPHILLIPS?

A:   After  the  merger  closing  date and the  final  assumption  of human
     resources responsibilities by ConocoPhillips,  calls seeking to verify
     past  employment  with BR should be  directed  to the Human  Resources
     Department of ConocoPhillips.

Q:   ARE  CONTRACT  OR  TEMPORARY  EMPLOYEES  GOING  TO BE  CONSIDERED  FOR
     REGULAR, FULL-TIME COP POSITIONS?

A:   Contract and  temporary  employees  are invited to apply for full-time
     ConocoPhillips  positions  through the career  site on  ConocoPhillips
     internet.

Q:   WHEN I  RECEIVE  MY OFFER  LETTER,  WHO  SHOULD  I TALK TO  ABOUT  ANY
     QUESTIONS I MIGHT HAVE?

A:   You should work with the  individual  who supplied  the letter  and/or
     your local HR  Business  Partner  (HRBP) to address any  questions  or
     concerns.

Q:   I MISSED THE EMPLOYEE PROFILE DEADLINE. CAN I STILL SUBMIT A PROFILE?

A:   The Employee Profile process has been closed.  If you are contacted by
     someone from ConocoPhillips who would like to know what your interests
     are or  would  like  to see a copy  of your  resume,  you may  send it
     directly to them if you like.
