                           Who is Covered by this Code

This Code of Business Conduct and Ethics (this "Code") applies to all Pioneer
employees, officers and directors and all contractors working at Pioneer
facilities or on behalf of Pioneer. Unless stated otherwise or the context
otherwise requires, when the term "employee" is used in this Code, it includes
all employees (including temporary employees and interns), officers and
directors and all contractors working at Pioneer facilities or on behalf of
Pioneer. When used in this Code, "Pioneer" or the "Company" means Pioneer
Natural Resources Company and its subsidiaries and affiliates.

                                  Getting Help

Our high ethical expectations and those of our stockholders require that Pioneer
employees work together to comply with this Code. All Pioneer employees have a
responsibility to read and understand this Code and report any action or
occurrence that does not meet the expectations of this Code.

This Code may not answer all of your questions. Or you may, during your
employment or interaction with Pioneer, encounter a situation not addressed by
this Code. You may also face a situation that makes you wonder if you or someone
else has a conflict of interest and can not act solely in Pioneer's best
interest.

It is your responsibility to read and become familiar with the contents of this
Code and to recognize and comply with the policies, rules and guidelines
contained in it. You are also responsible for seeking out answers about the
application of this Code. Pioneer is serious about the expectations set out in
this Code; therefore, a lack of understanding the Code will not be an excuse for
violating it.

There are several ways to ask questions or to report a concern related to this
Code. Use the method you are most comfortable with, but let someone in the list
below know. And if that person does not respond in a way that satisfies you, let
someone else on the list know.

*  Talk to your supervisor or another supervisor.

*  Talk to someone in the Human Resources Department.

*  Talk to the Company's Chief Compliance Officer or someone in the Legal
   Department by calling the corporate headquarters office at +1-972-444-9001
   or 1-800-242-2607.

*  Talk to someone in the Global Security Department by calling the corporate
   headquarters office at +1-972-444-9001 or 1-800-242-2607.

*  Contact the Compliance Line

   o  In the U.S.:       1-800-750-4972

   o  Outside the U.S.:  +1-704-973-0365 (call collect)

The Compliance Line is available 24 hours a day, 7 days a week. No one making a
report to the Compliance Line will be required to provide their name or other
identifying information, and no caller I.D. or recording devices will be used.

A means for interested parties to contact the Board of Directors directly
(including the Lead Director) has been established and is published on the
Company's website at www.pxd.com.
                                                                               5


                                  Introduction

Pioneer's longstanding policy is to comply with the letter and spirit of the
laws that govern the Company's business. Pioneer's commitment to honest and
ethical conduct extends beyond compliance with all laws and regulations. Pioneer
expects each employee to also act with integrity in everything he or she does.
Thus, Pioneer requires all employees to comply with the standards set forth in
this Code.

Pioneer cares about how business results are obtained, not just that they are
obtained. Pioneer will support any employee who passes up an opportunity or
advantage that would sacrifice our ethical standards.

In assessing whether an opportunity or advantage would risk sacrificing those
standards, Pioneer employees should consider the following:

*  Do I have enough information to adequately assess the possible benefits or
   risks of the opportunity or advantage? Have I provided all of the pertinent
   information that Pioneer's decision makers will need to evaluate whether or
   not Pioneer can ethically and legally approve this opportunity or
   advantage?

*  Would taking the opportunity or advantage:

   o  violate the letter or spirit of any applicable law or regulation?

   o  create a conflict between my personal interests and the interests of the
      Company, or otherwise violate the letter or spirit of this Code?

   o  cause any individual or the Company to fail to meet any of his, her or its
      commitments?

   o  be consistent with my personal principles?

*  Would I feel uncomfortable:

   o  telling my family about my decision or action?

   o  telling a government investigator or a jury about my decision or action?

   o  seeing my photograph in my local newspaper next to a report about my
      decision or action?

Pioneer employees who have any uncertainty about whether taking any action would
violate our ethical standards should discuss the matter with their supervisor
(or in the case of directors, with fellow directors) or seek advice from those
listed in the "Getting Help" section of this Code.

As part of Pioneer's commitment to maintaining the highest standards of conduct,
each Pioneer employee has an obligation to report possible violations of this
Code so that the conduct can be examined and Pioneer can be assured the conduct
complies with its culture of integrity.

In addition, directors, officers and supervisors of other employees are
responsible for

*  setting the proper tone through their own conduct, and

*  ensuring those who report to them understand the laws and policies that
   apply to their jobs and have taken necessary training on relevant
   compliance matters.

In particular, directors, officers and supervisors have a special duty of candor
in these areas; attempts by them to conceal information from other members of
higher management might be seen
                                                                               6


by subordinates or others as a signal that Pioneer's policies and rules can be
disregarded when inconvenient.

In selecting contractors, Pioneer will take into account the ability and
willingness of contractor candidates to comply with this Code. In selecting
vendors, Pioneer will take into account the vendor candidate's commitment not to
place Pioneer employees in situations that would cause them to violate this
Code.

Violations of this Code or other Pioneer policies will subject the violating
employee to discipline, which may include, without limitation, a warning,
suspension with or without pay and termination of employment.


================================================================================
                                   Please Note

*  This Code does not set out every one of Pioneer's policies, nor all the
   details of policies related to the topics described. If this Code conflicts
   with another Pioneer policy, you should seek clarification and direction
   from your supervisor.

*  Pioneer policies can be created or changed at any time, and Pioneer can
   interpret its policies in its discretion. Pioneer requires its employees to
   understand all the details of those policies and to comply with any new or
   changed policies as they are communicated.

*  For employees working in foreign jurisdictions, if complying with this Code
   would violate local law, those employees must follow local law. If local
   custom or policy conflicts with this Code, Pioneer expects this Code to be
   followed, even if the price is the loss of business for Pioneer.
================================================================================

Disclosures and Approvals

The forms for use in making the disclosures and obtaining the approvals required
by this Code are available on the Pioneer portal or from the Chief Compliance
Officer. Unless otherwise specified, whenever this Code requires the approval of
any relationship, investment, action or event, approval must be obtained in
advance from a member of the Pioneer Management Committee, if sought by an
employee other than a director or member of the Management Committee; from the
CEO, if sought by another member of the Management Committee; or from the Board
of Directors or its authorized committee, if sought by the CEO or a director.

To the extent that any relationship, investment, action or event was disclosed
or approved pursuant to a prior code of conduct of the Company, it need not be
disclosed or approved again following the adoption of this Code. Relationships,
investments, actions or events existing or pending at the time that this Code is
adopted that were not required to be disclosed or approved under a prior code of
conduct but are required to be disclosed or approved under this Code shall be
disclosed as soon as practicable, although approval shall not be required.

Waivers of this Code

Waivers of this Code are disfavored and will not be granted to executive
officers or directors. Waivers of this Code for other employees will only be
granted when exceptional circumstances apply. As a case may dictate, a waiver
may be accompanied by additional requirements or controls put in place to
protect Pioneer's interests.
                                                                               7


It is recognized that there will be questions about the application of this Code
to specific situations and requests for the approvals permitted under this Code.
In determining that the Code is not applicable or by granting a permitted
approval, the Company is not waiving the provisions of this Code. Additionally,
it shall not constitute a violation of this Code if a director or executive
officer of the Company makes a disclosure or requests an approval required under
this Code after the occurrence of the related investment, action or event, so
long as (i) the executive officer or director timely discloses the investment,
action or event, (ii) the investment, action or event does not otherwise
constitute a violation of this Code or require a waiver of this Code and (iii)
if approval is required, the investment, action or event is approved (or
ratified) in accordance with this Code.

In certain instances this Code speaks to the need for employees to comply with
other Company policies and procedures, either generally or specifically. In
doing so, it is not intended that a violation or waiver of another Company
policy will constitute a violation or waiver of this Code. Rather, such matters
will be addressed under the specific terms of those policies and procedures and
the Company's disciplinary procedures.

To ensure that waivers of this Code will be considered at the highest levels of
the Company, only the Pioneer Management Committee is authorized to grant
waivers permitted by this Code.

For employees other than executive officers and directors, requests for waivers
along with any supporting documentation should be submitted in writing to the
Pioneer Management Committee member to whom the employee ultimately reports with
copies to the Chief Compliance Officer and the General Counsel. A Pioneer
Management Committee member receiving a request for a waiver will distribute a
copy of the request and supporting material to the full Committee.

Any waiver will be disclosed to the extent and in the manner required by
applicable law and regulation.

                               The Places We Work
Safety

Pioneer's goal is to conduct its operations in a manner that protects the safety
of employees, others involved in its operations and the public. Accident
prevention is everyone's job and Pioneer employees each have a responsibility
not to endanger themselves or others. Pioneer employees must learn the safety
procedures relevant to their jobs and not begin or continue with any work
activity that is contrary to those procedures. Any Pioneer employee uncertain of
the safety procedures relevant to an operation must seek out a supervisor and be
trained in those procedures before beginning the operation. In addition, Pioneer
employees must use safety equipment as required by law, regulation and Pioneer
procedures, manuals, handbooks and guidelines.

Pioneer employees are expected to correct or report safety hazards as required
by law, regulation and Pioneer procedures, and to report all workplace accidents
no matter how minor. Supervisors are responsible for ensuring that Pioneer
complies with workplace accident reporting regulations.

Pioneer employees must learn emergency procedures for accidents and natural
disasters at their work sites. Supervisors are expected to ensure the employees
who report to them are aware of these emergency procedures.

In order to promote safety at Pioneer facilities, the Company reserves the right
to conduct searches on its property and to authorize searches by law enforcement
on its property, in either case with or without employees being present. As
circumstances warrant and as is consistent with applicable law,
                                                                               8


any person or vehicle entering a Pioneer facility is subject to search for
weapons, alcohol, drugs or any other prohibited items or substances.

Toxic Substances

Because an accident could have serious consequences, Pioneer employees must pay
special attention to safety and legal requirements for the storage, use and
disposal of toxic substances. Pioneer recognizes that the misuse of toxic
substances could have a substantial adverse effect on its employees, people
living or working near a Pioneer facility and the environment, and Pioneer is
committed to safe practices with regard to toxic substances.

Discrimination

Pioneer provides equal employment opportunity to each individual qualified to
perform the Company's job requirements, regardless of the individual's race,
color, sex, religion, national origin, age, disability, pregnancy, veteran or
marital status or status in any other group protected by law. Pioneer recognizes
that its greatest assets are its employees and that the proper utilization,
development and protection of Pioneer's human resources are the keys to
continued success. Pioneer will not tolerate illegal discrimination in hiring,
work assignments, promotion, compensation or any other aspect of the employment
relationship.

Consistent with this Code and legal requirements, Pioneer will make reasonable
accommodations to the known limitations of qualified employees or applicants
with disabilities, unless doing so would create undue hardship on the operation
of the business or cause a threat to the safety of co-workers or others.

Harassment

Harassment or intimidation on any basis, including race, gender or disability,
is unacceptable at any Pioneer workplace or Company-sponsored event and will not
be tolerated. Pioneer expects each employee to contribute to a workplace that
encourages respect for the contribution of co-workers to Pioneer's operations
and that is free of derogatory or discriminatory materials, statements or
remarks. The Company will not tolerate harassing, intimidating, offensive or
hostile comments or behavior based on a co-worker's (or anyone else's) race,
color, sex, religion, national origin, citizenship, age, disability, pregnancy,
veteran or marital status or status in any other group protected by law. Pioneer
also will not tolerate situations in which an employee must submit to
inappropriate conduct of this type to obtain or maintain employment,
compensation or promotion.

================================================================================
Supervisors and managers have a particular responsibility to maintain a
workplace free from discrimination and harassment and to promptly identify and
resolve any such issues.
================================================================================


Prohibited Substances

No one may use, possess, manufacture, distribute, dispense, conceal, receive,
transport or be under the influence of alcoholic beverages, controlled
substances, illegal drugs, drug paraphernalia or prescription drugs prescribed
for another during working hours, or at any time at a Pioneer facility, in
Company vehicles, while on Company business or, except as described below, at
Company-sponsored functions. In addition, Pioneer may restrict the work activity
or presence at a Pioneer facility of anyone taking a properly prescribed drug
that produces
                                                                               9


hazardous or unsafe effects, or affects an individual's job performance or
safety. Employees should inform their supervisor if they are taking any
medication that may produce these effects.

It is recognized that on occasion Pioneer may serve alcoholic beverages in
connection with a Company-sponsored function. In those situations, employees are
expected to exercise good judgment and moderation in their personal consumption.

To the extent consistent with applicable law, Pioneer employees may also be
required to submit to testing to determine the presence of illegal or
unauthorized substances.

Workplace Violence

Pioneer will not tolerate threats or acts of violent behavior against
co-workers, vendors, customers or others while conducting Company business or at
Company-sponsored functions, in or out of the workplace, on or off the clock.
Any Pioneer employee who becomes aware of a threat or act of violent behavior
(including by a third party) that has affected or may affect a Pioneer facility
or the people at or near the facility, should immediately notify his or her
supervisor of the details of the act or threat. Supervisors who receive such a
notification should immediately notify Pioneer's Global Security Department.
Nothing in this Code prevents or discourages a report being made directly to any
regulatory body or law enforcement agency.

Firearms and Weapons

Only authorized persons are permitted to possess (on their person or in a locker
or Company or personal vehicle) firearms or weapons on Company premises or while
on Company business. No Pioneer employee may possess (on their person or in a
locker or Company or personal vehicle) firearms, weapons, explosives or other
dangerous items or substances of any kind on Company premises or while on
Company business, unless approved.

================================================================================
                                   Quick Study

*  Learn the safety and emergency procedures relevant to your job and workplace.

*  Do not begin or continue with work activity that is contrary to those
   procedures. If you are unsure whether a work activity complies with these
   procedures, stop and ask.

*  Pay special attention to safety and legal requirements for the storage, use
   and disposal of toxic substances.

*  Illegal discrimination in hiring, work assignments, promotion, compensation
   or any other aspect of the employment relationship is unacceptable.

*  Do not harass or intimidate anyone on any basis at any Pioneer workplace or
   Company-sponsored event.

*  Do not use, possess, manufacture, distribute, dispense, conceal, receive,
   transport or be under the influence of alcoholic beverages, controlled
   substances, illegal drugs, drug paraphernalia or prescription drugs
   prescribed for another during working hours, or at any time at a Pioneer
   facility, in Company vehicles, while on Company business or at
   Company-sponsored functions (although moderate consumption of alcohol served
   at Company-sponsored functions is permitted).

*  Notify your supervisor of any threat of violent behavior, or an act of
   violent behavior, that has affected or may affect a Pioneer facility or the
   people at or near the facility.

*  Do not possess (on your person or in a locker or Company or personal vehicle)
   firearms, weapons, explosives or other dangerous items or substances of any
   kind on Company premises or while on Company business unless approved to do
   so.
================================================================================
                                                                              10


                           Our Relationship to Pioneer

Pioneer employees have been entrusted with the success of the Company. This
trust requires care in the way we act towards the Company, its assets and its
business.

Conflicts of Interest

Pioneer employees shall avoid any conflict between their personal interests and
the interests of the Company, and may not have any outside interest, investment
or business relationship that dilutes their loyalty to the Company. A "conflict
of interest" is any situation that prohibits an employee from working solely in
Pioneer's best interests. It is not feasible to identify every activity that
might give rise to a conflict of interest. The most common conflicts of interest
occur in the areas of outside activities, investments, loans, gifts and
entertainment, and personal use of corporate opportunities.

Pioneer recognizes that a conflict of interest could arise without the willful
action of an individual. A Pioneer employee who senses involvement in a possible
conflict of interest situation is required to disclose that matter to his or her
supervisor (or, in the case of a director, to the Board of Directors or its
authorized committee), making a full report of all pertinent facts and
circumstances. Each situation will be judged on its merits considering the
duties of the employee and the relative significance of the factors involved. To
avoid a possible conflict of interest, Pioneer may propose to modify the duties
(and, if advisable, the compensation) of an employee found to have a possible
conflict of interest until such time as the possible conflict is resolved.
Supervisors who receive such reports are specially charged with ensuring that
all appropriate Pioneer personnel are aware of the possible conflict.

Outside Activities

Employment. Unless approved, no Pioneer employee may undertake employment with,
or serve as a director or trustee of or a consultant to any organization that
does business, seeks to do business or competes with Pioneer. Pioneer employees
must disclose to their supervisor (or, in the case of a director, to the Board
of Directors or its authorized committee) when an immediate family member
(child, stepchild, parent, stepparent, spouse, sibling or in-law) is employed
by, is a director or trustee of, or is a consultant to, any organization that
does business, seeks to do business or competes with Pioneer. The Pioneer
employee may not participate in any decisions that relate to that organization.

Service on Other Boards. Service as a director, trustee or similar position for
a private for-profit entity requires approval. Service as a director, trustee or
similar position for a publicly-traded entity is generally discouraged and
requires the consent of the Board of Directors or its authorized committee. No
review or approval is required for service on the board of a not-for-profit
charitable, educational or community organization whose activities are unrelated
to Pioneer's business or activities. Employees may serve as directors, trustees
or in similar positions of affiliated companies and such service may be part of
their normal work assignments. This section is not applicable to members of the
Company's Board of Directors, whose service on other boards is governed by the
Company's Corporate Governance Guidelines.
                                                                              11


Industry Activities. Pioneer employees participating in or taking positions with
industry trade associations must receive the prior written approval of their
supervisor. When acting on behalf of an industry or trade organization, Pioneer
employees should take care to ensure that their actions are seen as those of the
organization and not of Pioneer.

Investments

In order to preserve the loyalty of Pioneer's employees, the following
investments require approval (or, if such an investment is made without willful
action on the part of the employee, the investment shall be disclosed):

*  Ownership, by an employee or any immediate family member, of any financial
   interest in any non-public enterprise that does business, seeks to do
   business or competes with Pioneer.

*  Ownership, by an employee or immediate family member, of 2% or more of the
   outstanding shares of any publicly-traded entity that does business, seeks to
   do business or competes with Pioneer, or ownership of any lesser financial
   interest in a publicly-traded entity where the employee is in a position to
   influence decisions with respect to that entity and the investment is of a
   size or nature that tends to influence the employee's business decisions or
   compromise the employee's independent judgment.

*  Ownership, by an employee or immediate family member, of a contractual or
   real property interest (including royalty, working interest, net profits
   interest, etc.) in any property owned or operated by Pioneer, other than an
   interest acquired through a Pioneer-sponsored program.

*  Any other personal investment that has the effect of diluting the employee's
   loyalty to Pioneer.

Loans

Loans to, or guarantees of obligations of, directors, executive officers, or
members of their families are specifically prohibited to the full extent
required by applicable law or regulation or by the listing standards of the New
York Stock Exchange. Pioneer employees may make loans with financial
institutions with which Pioneer does business (or that seek to do business with
Pioneer) only on arms-length terms available to similarly situated individuals
in the general public. Pioneer employees may not otherwise make loans with, or
accept guarantees of loans from, organizations that do business, seek to do
business or compete with Pioneer.

Accepting Gifts and Entertainment

Neither Pioneer employees nor their immediate family members will solicit or
accept gifts or entertainment or business courtesies of a size or nature that
tends to influence the Pioneer employee's business decisions or compromise the
Pioneer employee's independent judgment from organizations doing business,
seeking to do business or competing with Pioneer. Nor will Pioneer employees or
their immediate family members solicit or accept gifts, entertainment or
business courtesies (1) where the full facts are concealed by the employee, (2)
resulting in special or favored treatment for the donor, (3) creating or
implying a business obligation, or (4) otherwise creating a conflict between the
Pioneer employee's personal interests and the best interests of Pioneer. Under
no circumstances may cash gifts be solicited or accepted.

Subject to the limitations above, Pioneer employees may accept customary
business courtesies such as meals and refreshments for immediate consumption and
entertainment, and routine promotional
                                                                              12


gifts and other items having a value that would not tend to influence business
decisions or compromise the employee's independent judgment. Employees should
take care that the frequency and value of these courtesies do not imply a
business obligation or otherwise create a conflict of interest.

To avoid the appearance that the giving of gifts to Pioneer employees or their
immediate family members is the way to obtain or maintain Pioneer business,
Pioneer will require disclosure of gifts or entertainment of a size or nature
that could be seen as capable of influencing business decisions or compromising
independent judgment. Examples of such gifts or entertainment include:

*  Discounts outside the ordinary course of the grantor's business

*  Golf, hunting or fishing trips or outings

*  Tickets to performances or sporting events

*  Services, sponsorships or contributions

*  Any gift, entertainment, sponsorship or contribution solicited by the
   employee

*  Any other special or unusual favors or considerations

Pioneer employees should familiarize themselves with all other Company policies
and procedures regarding the acceptance and disclosure of gifts.

Pioneer employees and their immediate family members should consider seeking
approval prior to soliciting or accepting any gifts, entertainment, sponsorships
or contributions from organizations doing business, seeking to do business or
competing with Pioneer, since a determination after solicitation or acceptance
that the action violates this Code would subject the employee to discipline.


Corporate Opportunities

Pioneer employees must not make use of business opportunities discovered or
learned through the use of Pioneer property, information or the employee's
position at Pioneer for personal gain or for the benefit of an immediate family
member, except under the limited circumstances described below. Pioneer expects
every employee to work to promote the business and legitimate interests of the
Company. No Pioneer employee may take personal advantage of a business
opportunity learned through the use of Pioneer property, information or the
employee's position at Pioneer unless such opportunity has been rejected in
writing by the Company and the employee would not be prohibited from taking
advantage of the opportunity by this Code or any other Company policy. The
Company's rejection must be received from the Management Committee (or, if a
Management Committee member or a director wishes to take advantage of the
opportunity, from the Board of Directors or its authorized committee).
                                                                              13


================================================================================
                                   Quick Study

*  Avoid any conflict between your personal interests and the interests of the
   Company.

*  Obtain approval prior to serving as an employee, director, trustee or
   consultant of any organization that does business, seeks to do business or
   competes with Pioneer. Disclose to your supervisor when an immediate family
   member has such a position.

*  Do not serve as a director, trustee or similar position with any other public
   or private for-profit entity without approval.

*  Obtain your supervisor's approval prior to participating in or taking a
   position with an industry trade association.

*  Obtain approval (or provide disclosure, as required) of personal investments
   by you or immediate family members that have the effect of diluting your
   loyalty to Pioneer, including:

   o  Ownership of any financial interest in a non-public enterprise that does
      business, seeks to do business or competes with Pioneer;

   o  Ownership of 2% or more of the outstanding shares of a public entity that
      does business, seeks to do business or competes with Pioneer, or ownership
      of any lesser financial interest in a public entity where the investment
      is of a size or nature that tends to influence the employee's business
      decisions;

   o  Ownership of an interest in any real property owned or operated by
      Pioneer, other than an interest acquired through a Pioneer-sponsored
      program.

*  Loans with financial institutions with which Pioneer does business (or that
   seek to do business with Pioneer) must be on arms-length terms. Do not
   otherwise make loans with or accept guarantees of loans from organizations
   that do business, seek to do business or compete with Pioneer.

*  Do not solicit or accept gifts of a size or nature that tends to influence
   your business decisions or compromise your independent judgment from any
   organization that does business, seeks to do business or competes with
   Pioneer.

   capable of influencing business decisions, such as golf, hunting or fishing
   trips or outings; gifts, entertainment, sponsorships or contributions
   solicited from others by you; tickets to performance or sporting events;
   services, sponsorships or contributions; or other special or unusual favors
   or considerations.

   the use of Pioneer property, information or position, unless rejected by
   Pioneer.

                                                                              14


Confidentiality of Pioneer Information

Pioneer employees must protect from unauthorized disclosure all confidential
information disclosed to them by or on behalf of the Company or otherwise
acquired during the course of employment. This includes information disclosed by
Pioneer's customers, partners, vendors and agents. Pioneer has invested
significant resources in the development of business plans and processes that
give it a competitive advantage in the market. The investment in these assets
must be protected. Pioneer employees must comply with all Company security
procedures related to its information assets and systems.

Consistent with Pioneer's privacy policies, Pioneer employees should be given
access to employee personal data and personal information only on a "need to
know" basis, and employees with such access must limit their use of the
information to the business purpose for which they were given access.

In addition, Pioneer has an obligation to protect the confidential information
given to the Company by others. Pioneer employees given access to such
information must limit their use of that information to the purpose for which
they were given access.

The obligation to preserve confidential, proprietary or privileged Pioneer
information continues even after the employment or contractual relationship with
Pioneer ends.

Protection of Company Assets

Pioneer expects its employees to comply with all Company security procedures for
protecting Company assets and to use them for business purposes. Pioneer expends
considerable resources to develop and maintain assets used in its business.
Pioneer equipment and supplies are not acquired or maintained for personal use
by employees.

All Pioneer employees must protect Pioneer assets and ensure their efficient
use. Waste, carelessness and theft all have a direct impact on Pioneer's
profitability.

Pioneer employees must use the Company's assets, especially personal electronic
devices such as computers, PDAs and mobile phones, and electronic information or
access, in a manner consistent with the legitimate business interests of the
Company and Company policies. Any incidental personal use should be limited and
must not interfere with the Company's operations. Employees should not have any
expectation of privacy when using Company assets.

Protecting Pioneer's assets includes the obligation to ensure that, in dealing
with vendors, Pioneer gets the value for which it paid. Employees should remain
vigilant that invoices are accurate and materials and services meet the required
specifications.

Records Creation

Pioneer employees must prepare records accurately, completely and on time. All
funds, assets, receipts and disbursements of the Company must be properly
recorded on the books of the Company. In particular:

*  No accounts will be established or maintained for purposes that are not
   fully, fairly and accurately reflected on Pioneer's books and records.

*  No funds or other assets will be received or disbursed without being fully,
   fairly and accurately reflected on Pioneer's books and records.
                                                                              16


*  No false, fictitious or intentionally misleading entries will be made on
   Pioneer's books or records, and no false or misleading reports pertaining to
   Pioneer or its operations shall be prepared or distributed.

The falsification or alteration of a Company record to impede an investigation,
audit or lawsuit may result in significant criminal penalties for the individual
involved and Pioneer.

Any Pioneer employee who is asked, encouraged or coerced into preparing an
inaccurate record must immediately report that fact utilizing one of the avenues
listed in the "Getting Help" section of this Code.

Records Management

Every Pioneer employee is expected to be familiar with the requirements of
Pioneer's information management policies. Any employee with a question about
whether a Pioneer record must be retained or may be disposed of should contact
the Records Management Department.

The disposal or alteration of a Company record to impede an investigation, audit
or lawsuit may result in significant criminal penalties for the individual
involved and Pioneer. Any Pioneer employee who is asked, encouraged or coerced
into destroying a Company record for these purposes must immediately report that
fact to the Legal Department or the Compliance Line.

Cooperation with Company Investigations

Each Pioneer employee has a duty to assist the Company in investigating possible
violations of this Code or Company policy. Intentionally misleading a Company
investigation is a serious matter most likely to result in termination; in some
instances, it may be illegal and could result in criminal penalties.

Cooperation with Auditors

Pioneer employees and persons acting under their direction must never directly
or indirectly take action to fraudulently influence, coerce, manipulate or
mislead any independent or external accountant engaged in the performance of an
audit or review of financial statements. The Compliance Line (1-800-750-4972 in
the United States and collect at +1-704-973-0365 outside the United States) is
available to make reports regarding accounting, internal accounting controls or
auditing matters or for the confidential, anonymous submission by employees of
concerns regarding questionable accounting or auditing matters.

                                                                              16


================================================================================
                                   Quick Study

*  Protect confidential information acquired from the Company or others from
   unauthorized disclosure.

*  Comply with all Company security procedures related to its information
   assets and systems.

*  Give access to employee personal data and personal information only on a
   "need to know" basis.

   investigation, audit or lawsuit should be reported to the Legal Department
   or the Compliance Line.

   matters to the Compliance Line.
================================================================================


                        Pioneer's Relationship to Others

The Environment

Pioneer is dedicated to a healthy environment. The Company will comply with the
environmental laws and policies of the communities where it does business and
will make environmental issues and concerns a key part of its business decisions
and actions.

Pioneer employees are expected at a minimum to learn and follow the
environmental laws that govern at their work sites. Over and above these minimum
standards, Pioneer employees should take care to minimize, to the extent
reasonable in the circumstances, the impact of operations on the environment.

Pioneer employees are also expected to learn and follow the procedures and
safety standards for handling, disposing and transporting hazardous materials.
To the full extent required by law, regulation or facility procedure, Pioneer
employees must respond to and report spills or releases and take appropriate
remediation measures to minimize the impact on the environment.

Public and Securities Markets; Preservation of Pioneer's Reputation

Insider Trading.  Pioneer employees in possession of material, non-public
information regarding any company are prohibited from:

*  trading in that company's stock while in possession of that inside
   information;

                                                                              17


*  using the inside information for their own advantage or the advantage of
   others; or

*  "tipping" others who may buy or sell securities using the inside information.

The consequences for anyone accused of insider trading are severe. The mere
occurrence of an investigation for insider trading can destroy an employee's
reputation and effectively end a career with public companies. A conviction or
civil action can result in ruinous criminal or civil penalties.

Authorized Public Disclosure. Pioneer employees responsible for preparing
disclosures in financial reports and documents that the Company submits to the
United States Securities and Exchange Commission and in other public
communications are specially charged to ensure those disclosures and reports are
full, fair, accurate, timely and understandable. Any Pioneer employee who learns
that information in a disclosure or filing was untrue or misleading at the time
of the disclosure or filing or who becomes aware of information that may affect
future disclosures or filings should notify a member of the Pioneer Management
Committee or the Pioneer Disclosure Committee or call the Compliance Line.

In order to ensure that there are no inadvertent disclosures that would cause
the Company to be in violation of its obligations, only executive officers and
employees authorized to do so by the Corporate Communications Department, the
Investor Relations Department or a member of the Management Committee may make
public statements on behalf of Pioneer. Requests made of any Pioneer employee
for information about the business results of the Company should be referred to
the Investor Relations Department.

Unauthorized Corporate Communications. Pioneer employees speaking to friends or
associates, or in a public setting, need to bear in mind that their statements
may be seen as those of the Company. Written statements, emails, web postings
and blogs in the public realm may be associated with the Company. Employees
should be sure it is clear that they are expressing their own views and not
those of the Company.

Fair Dealing

No employee should take advantage of anyone through manipulation, concealment,
abuse of privileged information, misrepresentation of material facts or any
other technique or practice that would constitute unfair dealing. Employees
should take care to understand and observe Pioneer's contractual commitments.

Competitors and the Oil and Gas Market

Pioneer is committed to a marketplace of vigorous and fair competition for
suppliers and customers. Pioneer recognizes that violation of U.S. or foreign
competition laws is a serious matter and could place the Company or its
employees at risk of substantial criminal penalties. Pioneer employees must
avoid actions that undermine full and fair competition. Pioneer employees will
not:

*  disparage competitors;

*  misrepresent the attributes of Pioneer products or services or the products
   or services of competitors;

*  condition purchases or sales on reciprocal dealing;

*  agree with its competitors on the terms of any bids or other prices;

*  divide or allocate markets or customers; or
                                                                              18


*  agree with others to boycott other economic entities.

Employees should be especially mindful of these restrictions in connection with
participation in trade associations and in other situations in which employees
are interacting directly with the Company's competitors.

Commercial Kickbacks

No Pioneer funds or assets may be paid, loaned or otherwise disbursed as
kickbacks or other payments designed to influence or compromise the conduct of
the recipient. No Pioneer employee may accept any funds (other than compensation
from Pioneer) or other assets for assisting or obtaining business or securing
special concessions from Pioneer or any other person or entity. Pioneer insists
its employees conduct its business based on arms-length relationships. Among
others, the following conduct is expressly prohibited:

*  Payment or receipt of money, gifts, loans or other courtesies that, with
   respect to Pioneer, may tend to influence business decisions or compromise
   independent judgment.

*  Payment or receipt of rebates or kickbacks for obtaining business for or
   from Pioneer.

Pioneer may, consistent with its policies, the law and applicable regulation,
pay normal and reasonable commissions to agents, take normal and commercially
available prompt payment discounts, or give or receive gifts or services that
are consistent with customary social amenities and that do not tend to
compromise the independent conduct of the recipient.

Pioneer may, consistent with its policies, the law and applicable regulation,
entertain customers or other third parties with whom Pioneer deals in a manner
consistent with customary business practices. Customary business practices do
not include entertainment that would compromise impartiality or raise questions
about Pioneer's intentions or integrity. Pioneer employees are expected to
comply with any known restrictions on gifts or entertainment imposed by the
recipient's employer.

Any Pioneer employee who is solicited to make or accept a kickback or other
payment must immediately disclose the solicitation to his or her supervisor.
Supervisors notified of such solicitations have a special responsibility to
inform superiors and Pioneer's Global Security or Legal Department and to seek
their advice on the appropriate resolution of the solicitation.

Trade Secrets of Others

Pioneer employees must not improperly use or disclose any privileged,
confidential or proprietary information, intellectual property or trade secrets
of any former or concurrent employers or any other person.. Pioneer employees
must never request or encourage anyone to divulge the privileged, proprietary or
confidential information of their current or prior employers or any other
person.

Pioneer employees must collect information regarding the market or competitors
using only legitimate resources. Pioneer employees may never use methods that
are illegal or are contrary to the high standards of integrity expected of them
or that could cause embarrassment to Pioneer.

Intellectual Property of Others

Pioneer must fully comply with the terms of licensing agreements and laws (in
the United States and abroad) protecting copyrighted materials. Unauthorized
copying or transmission of

                                                                              19


copyrighted material is illegal. Employees must not reproduce or transmit
copyrighted material (including, but not limited to, written material, artwork,
photographs and software) without authorization or license. The Company
maintains licenses to make print and digital copies of certain publications for
internal use. Pioneer employees should contact the Legal Department to inquire
as to whether these licenses cover the intended action.

================================================================================

U.S. Government and Elected Officials

Pioneer's successful operations depend, to a great degree, on the Company's
ability to build relationships with government officials and employees based on
honesty and integrity.

Political Contributions. No Pioneer funds may be used for political
contributions in the United States. Pioneer employees who participate in
political campaigns must be careful to ensure that their activities do not cause
Pioneer to be deemed to have made an illegal contribution of

                                                                              20


Company funds, or an illegal in-kind contribution through the use of Company
property or services, or the use of Company employee work time.

Pioneer funds will not be used to buy tickets to special political dinners or
political fundraising events.

Pioneer employees will not solicit political contributions by or through
suppliers, customers or agents.

Personal political contributions to political parties, political action
committees or candidates are a matter of individual decision. No Pioneer
employee may represent that a personal political contribution is being made on
behalf of the Company.

No Pioneer employee may seek reimbursement, direct or indirect, from Pioneer for
any political contribution or purchase of a ticket to a political dinner or
political fundraising event.

Sponsorship by the Company of political action committees will be undertaken in
full compliance with applicable laws. Participation in any political action
committee sponsored by Pioneer is voluntary, and Pioneer will not favor or
disadvantage any employee by reason of the amount of his or her contribution or
decision not to contribute.

Foreign Governments and Elected Officials

Pioneer is committed to complying with the laws governing its foreign
operations.

Bribery of Government Officials. Pioneer employees are required to comply
strictly with the U.S. Foreign Corrupt Practices Act and the similar laws of
other countries that prohibit the bribery of government officials.

These laws prohibit Pioneer employees from offering, promising, paying or giving
money, gifts or anything with value: (i) to a government official in order to
influence him or her to act or not act or to direct business to Pioneer, or (ii)
to any person if the employee knows or is aware of a likelihood that all or any
part of the money, gift or thing with value will be used to influence a
government official.

"Government official" includes all government employees, ministers, members of
the legislature, armed forces personnel, employees, managers and directors of
government agencies and state-owned companies (including state oil companies),
political parties, party officials, candidates for political office, and
officials of public international organizations.

No Pioneer funds may be used for political contributions in any foreign country
unless approved by the Board of Directors or its authorized committee or by a
member of the Management Committee. Pioneer employees who participate in foreign
political campaigns must be careful to ensure that their activities comply with
Pioneer's policies and do not cause Pioneer to be deemed to have made an illegal
contribution of Company funds, or an illegal in-kind contribution through the
use of Company property or services, or the use of Company employee work time. A
Pioneer employee must request approval from the Legal Department prior to making
any political contribution in a country in which the employee is not permitted
to vote.

Pioneer employees must notify the Legal Department if (1) they are informed by
any person that making a payment or gift would assist Pioneer's efforts in doing
business or (2) they learn of the possibility that a payment or gift was made to
a government official to assist Pioneer's efforts in doing business.

                                                                              21



Some statutes may, in limited circumstances, allow for certain small
"facilitating" payments for routine governmental actions normally performed by
low-ranking officials engaged in ministerial duties. Pioneer employees must
obtain the approval of the Legal Department before making any such payment,
unless the payment is made in the context of an imminent threat to the health,
safety or welfare of a Pioneer employee, a member of his or her family, or a
co-worker. Any payment that is made under these circumstances must be reported
as soon as practicable to the Legal Department and must be properly recorded on
Pioneer's books and records.

The U.S. Foreign Corrupt Practices Act also requires Pioneer to maintain a
system of internal controls and keep adequate books and records to ensure that
cash and other assets are used for bona fide business purposes and are
transferred only in accordance with established Pioneer policies.

The Company has adopted procedures to support compliance with the U.S. Foreign
Corrupt Practices Act, which require, among other things, that specified due
diligence be performed with respect to certain partners, agents and vendors.
Pioneer employees should take care to understand their obligations under these
procedures and should contact the Legal Department with any questions as to
compliance with the Act.

Export Controls. Pioneer employees must comply with U.S. export control laws
that prohibit the export, re-export or transfer of certain goods, software or
technology to foreign countries and foreign nationals.

U.S. export laws require that export licenses be obtained from the U.S.
government in advance of exporting, re-exporting (shipping or transmitting from
one foreign country to another foreign country) or transferring certain goods,
software (including software with encryption capabilities) and technology
(including technical information) to foreign countries or foreign nationals. In
addition to the physical transfer or shipment of items, the law also covers the
"release" of technology to a foreign national, even inside the United States.
The "release" of technology can occur when foreign nationals visit Pioneer
facilities, engage with Pioneer employees in technical discussions or email
correspondence, or are parties with Pioneer in technical study and other
arrangements. The law even applies to foreign nationals who are employees and
representatives of, or consultants to, Pioneer in the U.S. and abroad.

Because an analysis of license requirements can be complex, employees should
contact the Legal Department before agreeing to export, transfer or release
sensitive goods or any software or technology to a foreign country or foreign
national.

U.S. Anti-boycott Law. No Pioneer employee will act in furtherance of any
boycott of any country, business or person that is prohibited by U.S. law.
Pioneer employees must report promptly to the Legal Department any received
request or instruction to act in furtherance of a boycott, or any inquiry as to
whether or not Pioneer already participates in such a boycott. Employees should
contact the Legal Department if they are unsure about the requirements of U.S.
anti-boycott law.

                                                                              22


U.S. Sanctions / Prohibited Parties. All Pioneer employees must comply with U.S.
laws that prohibit business and dealings with sanctioned countries and blocked
companies and individuals.

The U.S. maintains comprehensive, country-based sanctions against certain
countries from time to time. These comprehensive sanctions generally prohibit
all business and dealings with sanctioned countries and citizens of sanctioned
countries.

In addition, the U.S. government maintains the "Specially Designated Nationals
and Blocked Persons List," which identifies individuals and companies with whom
Pioneer is prohibited from conducting business. This List includes many
individuals and companies that are located outside of sanctioned countries,
including some located in the U.S.

Pioneer employees who have questions about the applicability of U.S. sanctions
should contact the Legal Department.

Cooperation in Government Investigations

Pioneer and its employees will cooperate whenever possible in governmental
investigations and will comply with valid and reasonable governmental requests
and demands for information. If government investigators want to inspect Company
premises, do not attempt to bar their entry into Company facilities. Immediately
contact the Legal Department or the Global Security Department, and maintain a
respectful demeanor without interfering with the investigators. Defer questions
to the highest ranking Company representative working at the facility or to the
Legal Department.

If contacted at home, you are free to speak or not speak with the government
investigator at that time or at some other time. You should strongly consider
whether you want a lawyer with you during any questioning and whether you want
to put off any questioning until you have consulted a lawyer. If you are
contacted at home, notify the Legal Department or the Global Security Department
at the earliest opportunity.

                                                                              23


================================================================================
                                  Quick Study:

*  No Pioneer funds may be used for political contributions in the United
   States or, without approval, in any foreign country.

*  Be careful your political activities do not cause Pioneer to be deemed to
   have made an illegal contribution of Company funds, or an illegal in-kind
   contribution through the use of Company property or services, or the use of
   Company employee work time.

*  Do not solicit political contributions by or through Pioneer suppliers,
   customers or agents.

*  Do not represent that a personal political contribution is being made on
   behalf of the Company.

*  Do not seek reimbursement, direct or indirect, from Pioneer for any
   political contribution or purchase of a ticket to a political dinner or
   political fundraising event.

*  Do not offer, promise or pay, directly or indirectly, bribes, gifts,
   gratuities, commissions, or the like to government officials (or for their
   benefit) to obtain favorable treatment for Pioneer.

*  Notify the Legal Department if informed by any person that making a payment
   or gift would assist Pioneer's efforts in doing business.

*  Obtain Legal Department approval before making any "facilitating" payment,
   unless doing so is not possible due to an imminent threat to health, safety
   or welfare.

*  Seek the advice of the Legal Department before agreeing to an export of
   sensitive goods or the transfer of technology.

*  Notify the Legal Department immediately if you are asked to participate in
   a boycott of any country or person or provide information in furtherance of
   a boycott.

*  Contact the Legal Department or the Global Security Department if
   government inspectors want to enter a Company facility, but do not attempt
   to bar their entry.
