                              OPINION OF COUNSEL

I am Vice President, General Counsel and Secretary of Vastar Resources, Inc.
(the "Company") and have acted as counsel for the Company in connection with
its Registration Statement on Form S-8 (the "Registration Statement")
relating to the registration under the Securities Act of 1933, as amended, of
an additional 200,000 shares of the Company's common stock, $0.01 par value (the
"Common Stock") issuable pursuant to the Company's Amended and Restated
Executive Long-Term Incentive Plan (the "Plan").

As the basis for the opinion hereinafter expressed, I have examined such
statutes, regulations, records and documents, certificates of corporate and
public officials and other instruments as I have deemed necessary or
advisable for the purposes of this opinion.  In such examination, I have
assumed the authenticity of all documents submitted to me as originals and
the conformity with the original documents of all documents submitted to me
as copies.

Based on the foregoing, certain consultations with officers, employees and
agents of the Company and on such legal considerations as I deem relevant, I
am of the opinion that the shares of Common Stock to be issued by the Company
pursuant to the Plan, when issued in accordance with the terms of the Plan,
will be validly issued, fully paid and nonassessable.

I am a member of the Bars of the States of Colorado, Missouri and Texas and I am
familiar with the general corporation law of the State of Delaware and the
federal laws of the United States, insofar as necessary for purposes of
rendering this opinion. I hereby consent to the use of this opinion as an
exhibit to the Registration Statement.

                                       Very truly yours,

                                       /s/  Albert D. Hoppe
