                     Re: Form S-1 Registration Statement SEC File No: 33-98042

Gentlemen:

       We have acted as counsel to National Energy Resources, Inc., a
California corporation ("Company"), in connection with the registration under
the Securities Act of 1933, as amended ("Act"), of certain beneficiary
interests in grantor trusts ("Trust Units") to be formed by investors as
beneficiaries and Boatmen's Trust Company ("Trustee") as trustee pursuant to
the form of Trust Agreement included in the Registration Statement upon the
closing of the offering for each Trust.  The total number of Trust Units
included in the Registration Statement is 6,000 with each Trust Unit
representing a contribution of $1,000 to the Trust.  Up to twelve Trusts may be
formed with each Trust issuing a minimum of 500 Trust Units.

       A Registration Statement on Form S-1 (Sec File No. 33-98042) under the
Act with respect to the Trust Units was filed with the Securities and Exchange
Commission on October 11, 1995 and amended by Amendment No. 1 filed June 13,
1996, and Amendment No. 2 filed October 4, 1996.

       We have examined and are familiar with originals or copies, the
authenticity of which has been established to our satisfaction, of all such
documents, corporate records, and other instruments as we have deemed necessary
to express the opinion hereinafter set forth.

       Based on the foregoing, it is our opinion that the Trust Units to be
sold by the Company in the manner described in the Registration Statement,
will, upon payment therefor and delivery thereof, be validity issued securities
of each of the Trusts, fully paid and non-assessable.

       You have further requested that we advise you of the anticipated United
States Federal income tax consequences of the Trusts.  The opinions in this
letter are based upon our interpretation of existing law, including legislative
history and proposed regulations relating to certain recent statutory changes.
Such existing law is subject to retroactive or prospective change by
legislation, administrative action or judicial decisions.  As to certain recent
statutory provisions, our opinion is based upon legislative history and
proposed Treasury Regulations which may be affected by final regulations.
These opinions are also based upon an analysis of the Trust Agreement and the
Company's representation that operations will adhere to the provisions of such
Agreement.  It is our opinion that the following Federal income tax

consequences will result (all references are to the Internal Revenue Code of
1986 (the "Code"), as amended, unless otherwise stated):

       1.     The Trust will be taxable as a grantor trust and not as an
              association taxable as a corporation.  As a grantor trust, the
              Trust will not be subject to tax at the trust level.  For tax
              purposes, the grantors (in this case, the Trust Unitholders) will
              be considered to own the Trust's income and principal as though
              no trust were in existence.

       2.     Each Trust Unitholder will be taxed directly on his pro rata
              share of the income of the Trust and will be entitled to claim
              his pro rata share of the deductions of the Trust.  The income of
              the Trust will be deemed to have been received or accrued by the
              Trust Unitholders at the time such income is received or accrued
              by the Trust and not when distributed by the Trust.

       3.     Based on representations made by National Energy, the reserves to
              be burdened by each Production Payment acquired by a Trust and
              the expected term of each Production Payment will be such that
              the Production Payments will meet the definition of a "production
              payment" under Section 636(a) of the Code.

       4.     It is more likely than not that all or substantially all of the
              state and local taxes imposed on the Trusts and the
              administrative expenses of the Trustee are deductible in
              computing adjusted gross income and, therefore, are not the type
              of miscellaneous itemized deductions that are allowable only to
              the extent that the aggregate of such deductions exceeds 2% of
              adjusted gross income.

       5.     The income and expenses of the Trust will not be taken into
              account in computing the passive activity losses and income under
              Code Section 469 for a Trust Unitholder who acquires and holds
              Trust Units as an investment.

       6.     A Trust Unitholder will realize gain or loss on the sale or
              exchange of his Trust Units measured by the difference between
              the amount realized on the sale or exchange and his adjusted
              basis for such Trust Units.  Gain or loss on the sale of Trust
              Units by a Trust Unitholder who is not a dealer with respect to
              such Trust Units and who has a holding period for the Trust Units
              of more than one year will be treated as long-term capital gain
              or loss under Subtitle A, Ch. 1 P. Part III of the Code, except
              possibly to the extent of ordinary income, if any, from accrued
              but undistributed income.  A Trust Unitholder's basis in his
              Trust Units will be equal to the amount paid for such Trust Units
              pursuant to this offering or pursuant to market transactions.

       7.     Distributions of Trust income generally will not be subject to
              "backup withholding" unless: (i) the Trust Unitholder is an
              individual or other noncorporate taxpayer and (ii) such Trust
              Unitholder fails to comply with certain reporting procedures and
              requirements under Code Section 3406.

       8.     The Production Payment shall be treated under Code Section 636(a)
              as if it were a mortgage loan on the property and shall not
              qualify as an economic interest in the mineral property.  Code
              Section 1275(d) gives the Treasury Secretary the power to
              prescribe regulations to carry out the purposes of the original
              issue discount ("OID") of the Code "where by reasons of varying
              rates of interest, put or call options, indefinite maturities,
              contingent payments, assumptions of debt instruments or other
              circumstances" the statutory provisions do not adequately carry
              out such purposes.  None of the proposed or final OID regulations
              provide any specific reference to or guidance with respect to
              production payments or deal with contingent payments as might
              reasonably be applied to production payments.  In the absence of
              final OID Regulation, the Production Payment under the offer
              appears to be governed by Code Section 636 and 483 and the
              regulations thereunder.

       The opinion expressed herein is as of the date hereof, is rendered
solely to National Energy Resources, Inc. in connection with the transaction
described herein, and may be relied upon only by National Energy Resources,
Inc. for the specific purposes herein set forth.  Any other use of this opinion
without our express consent is prohibited.

       We consent to the use of this opinion as an Exhibit to the above
mentioned Registration Statement and to the use of our name in such
Registration Statement and the Prospectus included therein under the heading
"Legal Matters".




                                                Very truly yours,

                                              ROBERTSON & WILLIAMS,
                                            A Professional Corporation
