  NOTES TO

  1.
    BASIS OF
    ACCOUNTING    
    Royalty income recorded for a month is the amount computed and
    paid with respect to the Trusts 75% net overriding royalty
    interest (the Royalty) in certain oil and gas
    leasehold and royalty interests (the Underlying
    Properties) by Burlington Resources Oil & Gas
    Company LP (BROG), the present owner of the
    Underlying Properties, to the Trustee for the Trust. Royalty
    income consists of the proceeds received by BROG from the sale
    of production from the Underlying Properties less accrued
    production costs, development and drilling costs, applicable
    taxes, operating charges, and other costs and deductions,
    multiplied by 75%. The calculation of net proceeds by BROG for
    any month includes adjustments to proceeds and costs for prior
    months and impacts the Royalty income paid to the Trust and the
    distribution to Unit Holders for that month.
    Trust expenses recorded are based on liabilities paid and cash
    reserves established from Royalty income for liabilities and
    contingencies.
    Distributions to Unit Holders are recorded when declared by the
    Trustee.
    The conveyance which transferred the Royalty to the Trust
    provides that any excess of development and production costs
    applicable to the Underlying Properties over gross proceeds from
    such properties must be recovered from future net proceeds
    before Royalty income is again paid to the Trust.  unit-of-production
