  VASTAR RESOURCES, INC., a corporation duly organized and existing under the laws of the State of Delaware (herein called the
"Company," which term includes any successor Person under the Indenture, as hereinafter defined), for value received, hereby
promises to pay to Cede & Co., or registered assigns, the principal sum of TWO HUNDRED MILLION DOLLARS on April 1, 2009 (the "Stated
Maturity"), and to pay interest thereon from March 31, 1999, or from the most recent Interest Payment Date (as hereinafter defined)
to which interest has been paid or duly provided for, semi-annually in arrears on April 1 and October 1 in each year (each an
"Interest Payment Date"), commencing October 1, 1999, at the rate of 6.50% per annum, until the principal hereof is paid or made
available for payment. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as
provided in the Indenture, be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered
at the close of business on the Regular Record Date for such interest, which shall be the March 15 or September 15 (whether or not a
Business Day), as the case may be, next preceding such Interest Payment Date. Any such Interest not so punctually paid or duly
provided for on any Interest Payment Date (herein called "Defaulted Interest") will forthwith cease to be payable to the Holder on
the relevant Regular Record Date and may either be paid to the Person in whose name this Security (or one or more Predecessor
Securities) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed
by the Trustee, notice of which shall be given to Holders of Securities of this series not less than 10 days prior to such Special
Record Date, or be paid by the Company at any time in any other lawful manner not inconsistent with the requirements of any
securities exchange on which the Securities of this series may be listed, and upon such notice as may be required by such exchange,
all as more fully provided in the Indenture.

  Payment of the principal of (and premium, if any, on) and interest payable at Stated Maturity on this Security will be made in
immediately available funds at the office or agency of the Company in the Borough of Manhattan, The City of New York, New York, in
such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private
debts, provided that this Security is presented to the Paying Agent in time for the Paying Agent to make such payments in such funds
in accordance with its normal procedures. Periodic payments of interest will be made by check mailed to the address of the Person
entitled thereto as it appears in the Security Register as of the applicable Regular Record Date or, at the option of the Company,
by wire transfer to an account maintained by such Person with a bank located in the United States.

  REFERENCE IS HEREBY MADE TO THE FURTHER PROVISIONS OF THIS SECURITY SET FORTH ON THE REVERSE HEREOF, WHICH FURTHER PROVISIONS
SHALL FOR ALL PURPOSES HAVE THE SAME EFFECT AS IF SET FORTH AT THIS PLACE.

  Unless the certificate of authentication hereon has been executed by the Trustee referred to on the reverse hereof by manual
signature, this Security shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

  IN WITNESS WHEREOF, the Company has caused this instrument to be duly executed under its corporate seal.

                         6.50% NOTES DUE APRIL 1, 2009

  This Security is one of a duly authorized issue of securities of the Company
(referred to herein as the "Securities"), issued and to be issued in one or more
series under an Indenture dated as of January 1, 1995 and as amended by
Supplemental Indentures dated as of May 18, 1995 and April 16, 1998 (and as it
may be further supplemented or amended from time to time, referred to herein as
the "Indenture") among the Company and Harris Trust and Savings Bank (successor
to NationsBank of Texas, N.A.), as trustee (referred to herein as the "Trustee,"
which term includes any successor trustee under the Indenture), and the Bank of
Montreal Trust Company, as paying agent (the "Paying Agent," which term includes
any successor paying agent under the Indenture), to which Indenture and all
indentures supplemental thereto reference is hereby made for a statement of the
respective rights, limitations of rights, duties and immunities thereunder of
the Company, the Trustee and the Holders of the Securities and of the terms upon
which the Securities are, and are to be, authenticated and delivered.  This
Security is one of the series designated on the face hereof, limited in
aggregate principal amount to $300,000,000.

  If an Event of Default with respect to Securities of this series shall occur
and be continuing, the principal of the Securities of this series may be
declared due and payable in the manner and with the effect provided in the
Indenture.

  The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities of each series to be
affected under the Indenture at any time by the Company and the Trustee with the
consent of the Holders of not less than a majority in principal amount of all
Securities at the time Outstanding of each series to be affected.  The Indenture
also contains provisions permitting the Holders of not less than a majority in
principal amount of the Outstanding Securities of any such series, on behalf of
the Holders of all Outstanding Securities of that series, to waive compliance by
the Company with certain provisions of the Indenture and certain past defaults
under the Indenture and their consequences.  Any such consent or waiver by the
Holder of this Security shall be conclusive and binding upon such Holder and
upon all future Holders of this Security and of any Security issued upon the
registration of transfer hereof or in exchange or substitution herefor or in
lieu hereof, whether or not notation of such consent or waiver is made upon this
Security.

  The Indenture contains provisions for the defeasance at any time of the entire
indebtedness of the Company on this Security upon compliance by the Company with
certain conditions set forth therein.

  As set forth in, and subject to, the provisions of the Indenture, no Holder of
any of the Securities of any series will have any right to institute any
proceeding, judicial or otherwise, with respect to the Indenture or for any
remedy thereunder, unless such Holder shall have previously given to the Trustee
written notice of a continuing Event of Default with respect to the Securities
of that series, the Holders of not less than 25% in aggregate principal amount
of the Outstanding Securities of that series shall have made written request to
the Trustee to institute such proceeding in respect of such Event of Default in
its own name as Trustee under the Indenture, such Holder or Holders have offered
to the Trustee reasonable indemnity against the costs, expenses and liabilities
to be incurred in compliance with such request, the Trustee shall have failed to
institute such proceeding within 60 days of receipt of such notice, request and
offer of indemnity, and the Trustee shall not have received from the Holders of
a majority in principal amount of the Outstanding Securities of that series a
direction inconsistent with such written request during the 60-day period;
provided, however, that such limitations do not apply to a suit instituted by
the Holder for the enforcement of payment of the principal of, premium, if any,
or interest on this Security on or after the respective due date expressed
herein.

  No reference herein to the Indenture and no provision of this Security or of
the Indenture shall, without the consent of the Holder, alter or impair the
obligation of the Company, which is absolute and unconditional, to pay the
principal of (and premium, if any) and interest on this Security at the times,
place and rate, and in the coin or currency, herein prescribed.

  As provided in the Indenture and subject to certain limitations therein set
forth, and except as otherwise restricted by a legend printed on the face
hereof, if any, the transfer of this Security may be registered in the Security
Register, upon surrender of this Security for registration of transfer at the
office or agency of the Company in any place where the principal of (and
premium, if any) and interest on this Security are payable, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the
Company, the Trustee and the Security Registrar duly executed by, the Holder
hereof or his attorney duly authorized in writing, and thereupon one or more new
Securities of this series, of authorized denominations and for the same
aggregate principal amount, will be issued to the designated transferee or
transferees.

  The Securities of this series are issuable only in registered form without
coupons in denominations of $1,000 and any integral multiple thereof.  As
provided in the Indenture and subject to certain limitations therein set forth,
and except as otherwise restricted by a legend printed on the face hereof, if
any, Securities of this series are exchangeable for a like aggregate principal
amount of Securities of this series of a different authorized denomination, as
requested by the Holder surrendering the same.

  No service charge shall be made for any such registration of transfer or
exchange, but the Company may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.  Expenses may
be charged for replacing mutilated, destroyed, lost or stolen Securities,
provided the requirements for replacement are satisfied.

  Prior to due presentment of this Security for registration of transfer, the
Company, the Trustee and any agent of the Company or the Trustee may treat the
Person in whose name this Security is registered as the owner hereof for all
purposes, whether or not this Security be overdue; and none of the Company, the
Trustee or any such agent shall be affected by notice to the contrary.

ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE
AND TO BE PERFORMED IN THAT STATE.

  All terms used in this Security which are defined in the Indenture shall have
the meanings assigned to them in the Indenture.
