                         ------------------------------

Item 1.   Financial Statements.

     The financial statements included herein have been prepared by NationsBank
of Texas, N.A., as Trustee (the "Trustee") of Williams Coal Seam Gas Royalty
Trust (the "Trust"), pursuant to the rules and regulations of the Securities and
Exchange Commission.  Certain information and footnote disclosures normally
included in annual financial statements have been condensed or omitted pursuant
to such rules and regulations, although the Trustee believes that the
disclosures are adequate to make the information presented not misleading.  It
is suggested that these condensed financial statements be read in conjunction
with the financial statements and notes thereto incorporated by reference in the
Trust's Annual Report on Form 10-K for the year ended December 31, 1996.  The
December 31, 1996 balance sheet is derived from the audited balance sheet of
that date.  In the opinion of the Trustee, all adjustments, consisting only of
normal recurring adjustments, necessary to present fairly the assets,
liabilities and trust corpus of the Trust as of March 31, 1997, and the
distributable income and the changes in trust corpus for the three-month periods
ended March 31, 1997 and 1996, have been included.  The distributable income for
such interim periods is not necessarily indicative of the distributable income
for the full year.

     The financial statements as of March 31, 1997 and for the three-month
periods ended March 31, 1997 and 1996 included herein have been reviewed by
Ernst & Young LLP, independent public accountants, as stated in their report
appearing herein.

                     Independent Accountants' Review Report

NationsBank of Texas, N.A.,
  Trustee of Williams Coal Seam Gas Royalty Trust

We have reviewed the accompanying condensed statement of assets, liabilities and
trust corpus of the Williams Coal Seam Gas Royalty Trust as of March 31, 1997,
and the related condensed statements of distributable income and the statements
of changes in trust corpus for the three-month periods ended March 31, 1997 and
1996.  These financial statements are the responsibility of the Trustee.

We conducted our reviews in accordance with standards established by the
American Institute of Certified Public Accountants.  A review of interim
financial information consists principally of applying analytical procedures to
financial data, and making inquiries of persons responsible for financial and
accounting matters.  It is substantially less in scope than an audit conducted
in accordance with generally accepted auditing standards, which will be
performed for the full year with the objective of expressing an opinion
regarding the financial statements taken as a whole.  Accordingly, we do not
express such an opinion.

As described in Note 2 to the financial statements, these financial statements
have been prepared on a modified cash basis of accounting, which is a
comprehensive basis of accounting other than generally accepted accounting
principles.

Based on our reviews, we are not aware of any material modifications that should
be made to the accompanying condensed financial statements referred to above for
them to be in conformity with the basis of accounting described in Note 2.

We have previously audited, in accordance with generally accepted auditing
standards, the statement of assets, liabilities and trust corpus of the Williams
Coal Seam Gas Royalty Trust as of December 31, 1996, and the related statements
of distributable income and changes in trust corpus for the year then ended (not
presented herein) and in our report dated March 21, 1997, we expressed an
unqualified opinion on those financial statements.  In our opinion, the
information set forth in the accompanying condensed statement of assets,
liabilities and trust corpus as of December 31, 1996, is fairly stated, in all
material respects, in relation to the statement of assets, liabilities and trust
corpus from which it has been derived.

WILLIAMS COAL SEAM GAS ROYALTY TRUST

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
--------------------------------------------------------------------------------

1.  TRUST ORGANIZATION AND PROVISIONS

    Williams Coal Seam Gas Royalty Trust (the "Trust") was formed as a Delaware
business trust pursuant to the terms of the Trust Agreement of Williams Coal
Seam Gas Royalty Trust (as amended, the "Trust Agreement") entered into
effective as of December 1, 1992 by and among Williams Production Company, a
Delaware corporation ("WPC"), as trustor, The Williams Companies, Inc., a
Delaware corporation ("Williams"), and NationsBank of Texas, N.A., a national
banking association (the "Trustee"), and Chemical Bank Delaware, a Delaware
banking corporation (the "Delaware Trustee"), as trustees.  The trustees are
independent financial institutions.

    The Trust was formed to acquire and hold certain net profits interests (the
"Royalty Interests") in proved natural gas properties located in the San Juan
Basin of New Mexico and Colorado (the "Underlying Properties") owned by WPC.
The Trust was initially created effective as of December 1, 1992 with a $100
contribution by WPC.  On January 21, 1993, the Royalty Interests were conveyed
to the Trust by WPC pursuant to the Net Profits Conveyance (the "Conveyance")
dated effective as of October 1, 1992 by and among WPC, Williams, the Trustee
and the Delaware Trustee, in consideration for all the 9,700,000 authorized
units of beneficial interest in the Trust ("Units").  WPC transferred its Units
by dividend to its parent, Williams, which sold an aggregate of 5,980,000 Units
to the public through various underwriters in January and February 1993 (the
"Public Offering").  During the second quarter of 1995 Williams transferred its
Units to Williams Holdings of Delaware, Inc. (WHD), a separate holding company
for Williams' non regulated businesses.  Substantially all of the production
attributable to the Underlying Properties is from the Fruitland coal formation
and constitutes "coal seam" gas that entitles the owners of such production,
provided certain requirements are met, to tax credits for Federal income tax
purposes pursuant to Section 29 of the Internal Revenue Code of 1986, as
amended.

    The Trustee has the power to collect and distribute the proceeds received by
the Trust and to pay Trust liabilities and expenses.  The Delaware Trustee has
only such powers as are set forth in the Trust Agreement and is not empowered to
otherwise manage or take part in the business of the Trust.  The Royalty
Interests are passive in nature and neither the Delaware Trustee nor the Trustee
has any control over or any responsibility relating to the operation of the
Underlying Properties.

    The Trust will terminate no later than December 31, 2012, subject to earlier
termination under certain circumstances described in the Trust Agreement (the
"Termination Date").  Cancellation of the Trust will occur on or following the
Termination Date when all Trust assets have been sold and the net proceeds
thereof distributed to Unitholders.

    The only assets of the Trust, other than cash and cash equivalents being
held for the payment of expenses and liabilities and for distribution to
Unitholders, are the Royalty Interests.

                                       7
<PAGE>
 
The Royalty Interests consist primarily of a net profits interest (the "NPI") in
the Underlying Properties.  The NPI generally entitles the Trust to receive 81
percent of the NPI Net Proceeds, as defined below, attributable to (i) gas
produced and sold from WPC's net revenue interests (working interests less lease
burdens) in the properties in which WPC has a working interest (the "WI
Properties") and (ii) the revenue stream received by WPC attributable to its 35
percent net profits interest in 5,348 gross acres in La Plata County, Colorado
(the "Farmout Properties").  The Royalty Interests also include a 20 percent
interest in WPC's Infill Net Proceeds, as defined below, from the sale of
production if well spacing rules are effectively modified and additional wells
are drilled on producing drilling blocks on the WI Properties (the "Infill
Wells") during the term of the Trust.  No Infill Wells have been drilled on the
WI Properties to date.  "NPI Net Proceeds" consists generally of the revenue
stream received by WPC from its 35 percent net profits interest in the Farmout
Properties, plus the aggregate proceeds attributable to WPC's net revenue
interest, based on the price paid at or in the vicinity of the wellhead (the
"Wellhead"), of gas produced from the WI Properties, less WPC's share of certain
taxes and costs.  "Infill Net Proceeds" consists generally of the aggregate
proceeds, based on the price at the Wellhead, of gas produced from WPC's net
revenue interest in any Infill Wells less certain taxes and costs.  The NPI
percentage is subject to certain future downward adjustments based on a rate of
return computation once cumulative aggregate production targets are met.  The
complete definitions of NPI Net Proceeds and Infill Net Proceeds are set forth
in the Conveyance.

2.  BASIS OF ACCOUNTING

    The financial statements of the Trust are prepared on a modified cash basis
and are not intended to present financial position and results of operations in
conformity with generally accepted accounting principles ("GAAP").  Preparation
of the Trust's financial statements on such basis includes the following:

    Revenues are recognized in the period in which amounts are received by the
    Trust.  General and administrative expenses are recognized on an accrual
    basis.

    Amortization of the Royalty Interests is calculated on a unit-of-production
    basis and charged directly to trust corpus.

    Distributions to Unitholders are recorded when declared by the Trustee (see
    Note 4).

    The financial statements of the Trust differ from financial statements
prepared in accordance with GAAP because royalty income is not accrued in the
period of production and amortization of the Royalty Interests is not charged
against operating results.

    Williams sold an aggregate of 5,980,000 Units of the Trust's authorized
9,700,000 Units in the Public Offering at the offering price of $20 per Unit,
retaining 3,720,000 Units.  Subsequently, Williams sold an additional 151,209
Units for $23.50 per Unit.  Accordingly, the condensed statements of assets,
liabilities and trust corpus reflect the sale of these Units at the respective
sale prices thereof, as well as the remaining 3,568,791 Units at Williams'
historical cost.  During the second quarter of 1995 Williams transferred its
Units to WHD, a separate holding company for Williams' non regulated businesses.
If WHD, in the future, should sell

                                       8
<PAGE>
 
all or a portion of its retained Units, at that time, the carrying value on the
Trust's statements of assets, liabilities and trust corpus would again be
adjusted from WHD's historical cost to the subsequent sale price with respect to
the Units sold.

3.  FEDERAL INCOME TAXES

    The Trust is a grantor trust for Federal income tax purposes.  As a grantor
trust, the Trust will not be required to pay Federal or state income taxes.
Accordingly, no provision for income taxes has been made in these financial
statements.

    Because the Trust will be treated as a grantor trust, and because a
Unitholder will be treated as directly owning an interest in the Royalty
Interests, each Unitholder will be taxed directly on his per Unit pro rata share
of income attributable to the Royalty Interests consistent with the Unitholder's
method of accounting and without regard to the taxable year or accounting method
employed by the Trust.

    Production from coal seam gas wells drilled after December 31, 1979 and
prior to January 1, 1993, qualifies for the Federal income tax credit for
producing nonconventional fuels under Section 29 of the Internal Revenue Code.
This tax credit is calculated annually based on each year's qualified production
through the year 2002.  Such credit, based on the Unitholder's pro rata share of
qualifying production, may not reduce his regular tax liability (after the
foreign tax credit and certain other non-refundable credits) below his
alternative minimum tax.  Any part of the Section 29 credit not allowed for the
tax year solely because of this limitation is subject to certain carryover
provisions.  Each Unitholder should consult his tax advisor regarding Trust tax
compliance matters.

4.  DISTRIBUTIONS TO UNITHOLDERS

    The Trustee determines for each quarter the amount of cash available for
distribution to Unitholders.  Such amount (the "Quarterly Distribution Amount")
is an amount equal to the excess, if any, of the cash received by the Trust, on
or prior to the last day of the month following the end of each calendar quarter
from the Royalty Interests, plus, with certain exceptions, any other cash
receipts of the Trust during such quarter, over the liabilities of the Trust
paid during such quarter, subject to adjustments for changes made by the Trustee
during such quarter in any cash reserves established for the payment of
contingent or future obligations of the Trust.

    The Quarterly Distribution Amount for each quarter is payable to Unitholders
of record on the 45th day following the end of such calendar quarter unless such
day is not a business day in which case the record date is the next business day
thereafter.  The Trustee distributes the Quarterly Distribution Amount within 60
days after the end of each calendar quarter to each person who was a Unitholder
of record on the associated record date, together with interest estimated to be
earned on such amount from the date of receipt thereof by the Trustee to the
payment date.

    In addition to the regular quarterly distributions, under certain
circumstances specified in the Trust Agreement (such as upon a purchase price
adjustment, if any, or pursuant to the sale

                                       9
<PAGE>
 
of a Royalty Interest), the Trust would make a special distribution (a "Special
Distribution Amount").  A Special Distribution Amount would be made when amounts
received by the Trust under such circumstances aggregated in excess of
$9,000,000.  The record date for a Special Distribution Amount will be the 15th
day following receipt of amounts aggregating a Special Distribution Amount by
the Trust (unless such day is not a business day in which case the record date
will be the next business day thereafter) unless such day is within 10 days of
the record date for a Quarterly Distribution Amount in which case the record
date will be the date as is established for the next Quarterly Distribution
Amount.  Distribution to Unitholders of a Special Distribution Amount will be
made no later than 15 days after the Special Distribution Amount record date.

5.    SUBSEQUENT EVENTS

    Subsequent to March 31, 1997, the Trust declared the following distribution:

             <S>                  <C>                  <C>
                                          
              May 15               May 30                $.617428
</TABLE>

    The distribution per unit increased from $.408865 in the first quarter of
1997 to $.617428 in the second quarter of 1997. The increase in distributions
was mainly the result of higher payments from the Farmout Properties. The
Farmout Properties are paid at the Blanco Hub Spot Price. 

    Expansions of federal unit acreage can either increase or decrease the
Trust's ownership of particular wells resulting in potential adjustments of
production for prior periods and associated distributions to unitholders can
either increase or decrease. Federal unit acreage expansions are determined by
the commercial value of the property as valued by the operator and approved by
the U.S. Bureau of Land and Mines (BLM). WPC does not operate any wells in these
federal acreage units.

6.  CONTINGENCIES

    Under the terms of the gas purchase contract entered into by WPC and WFS Gas
Resources Company ("WFSGR"), an affiliate of WPC, as amended (the "Gas Purchase
Contract"), additional revenues may be paid to the Trust to meet the minimum gas
price provision of 97 percent of $1.75 per MMBtu (the "Minimum Purchase Price").
This additional revenue is subject to recoupment by the purchaser from future
revenues received from production commencing January 1, 1994 when the applicable
index price exceeds the Minimum Purchase Price as long as the Minimum Purchase
Price commitment is in effect.  The primary term of the Gas Purchase Contract
runs to December 31, 1997 at which time the WFSGR may elect to discontinue
paying the Minimum Purchase Price by giving notice of its election to pay solely
on an index price.

    The applicable index price was above the Minimum Purchase Price in January
and February of 1997 and was below the Minimum Purchase Price in March of 1997.
Pursuant to the terms of the Gas Purchase Contract, WPC established a price
credit account. WPC estimates that, as of March 31, 1997, WFSGR had aggregate
price credits in the price credit account of approximately $21.6 million of
which the Trust's 81 percent interest was approximately $17.5 million. The
applicable index price was below the Minimum Purchase Price in April 1997.

                                       10
<PAGE>
 
    The entitlement of WFSGR to recoup the price credits means that if and when
the applicable Blanco Hub Spot Price rises above $1.75 per MMBtu, future royalty
income paid to the Trust would be reduced until such time as such price credits
have been fully recouped.  Corresponding cash distributions to Unitholders would
also be reduced.

7.  TRANSACTION INVOLVING UNDERLYING PROPERTIES SUBSEQUENT TO MARCH 31, 1997

    On May 7, 1997, WPC sold the Underlying Properties to Quatro Finale LLC
pursuant to the Purchase and Sale Agreement dated as of May 1, 1997 between WPC
and Quatro Finale LLC (the "Purchase Agreement"), subject to the terms and
conditions set forth in the Purchase Agreement and the agreements entered into
pursuant to the Purchase Agreement (the "Transaction").  The information and
descriptions set forth in this Form 10-Q do not give any effect to the
Transaction, which was consummated subsequent to March 31, 1997.  The Trust
plans to file a Current Report on Form 8-K to describe the Transaction.
 
Item 2.  Trustee's Discussion and Analysis of Financial Condition
         and Results of Operations.

     On May 7, 1997, Williams Production Company ("WPC") sold the Underlying
Properties (as defined herein) to Quatro Finale LLC pursuant to the Purchase and
Sale Agreement dated as of May 1, 1997 between WPC and Quatro Finale LLC (the
"Purchase Agreement"), subject to the terms and conditions set forth in the
Purchase Agreement and the agreements entered into pursuant to the Purchase
Agreement (the "Transaction").  The information and descriptions set forth in
this Form 10-Q do not give any effect to the Transaction.  The Trust plans to
file a Current Report on Form 8-K to describe the Transaction.

     The Trust makes quarterly cash distributions to holders of units of
beneficial interest ("Units") in the Trust ("Unitholders").  The only assets of
the Trust, other than cash and cash equivalents being held for the payment of
expenses and liabilities and for distribution to Unitholders, are net profits
interests (the "Royalty Interests") in certain proved coal seam gas properties
located in the San Juan Basin of New Mexico and Colorado (the "Underlying
Properties").  The Royalty Interests owned by the Trust burden the Underlying
Properties, which are owned by WPC and not the Trust.

     Distributable income of the Trust consists of the excess of royalty income
plus interest income over the general and administrative expenses of the Trust.
Upon receipt by the Trust, royalty income is invested in short-term investments
in accordance with the Trust Agreement (as defined in Note 1 to the financial
statements of the Trust appearing elsewhere in this Form 10-Q ("Note 1")) until
its subsequent distribution to Unitholders.

                                       11
<PAGE>
 
     The amount of distributable income of the Trust for any quarter may differ
from the amount of cash available for distribution to Unitholders in such
quarter due to differences in the treatment of the expenses of the Trust in the
determination of those amounts.  The financial statements of the Trust are
prepared on a modified cash basis pursuant to which the expenses of the Trust
are recognized when incurred.  Consequently, the reported distributable income
of the Trust for any quarter is determined by deducting from the income received
by the Trust the amount of expenses incurred by the Trust during such quarter.
The amount of cash available for distribution to Unitholders, however, is
determined in accordance with the provisions of the Trust Agreement and reflects
the deduction from the income actually received by the Trust of the amount of
expenses actually paid by the Trust and adjustments for changes in reserves for
unpaid liabilities.  See Note 4 to the financial statements of the Trust
appearing elsewhere in this Form 10-Q for additional information regarding the
determination of the amount of cash available for distribution to Unitholders.

Three Months Ended March 31, 1997 Compared to Three Months Ended March 31, 1996
-------------------------------------------------------------------------------

     For the quarter ended March 31, 1997, royalty income received by the Trust
amounted to $4,103,814 as compared to $6,529,043 received for the same quarter
in 1996.  The decrease in royalty income is primarily due to adjustments
resulting from expansion of federal units within the Underlying Properties.
Production related to the royalty income received by the Trust in the first
quarter of 1997 was 4,834,264 MMBtu as compared to 8,050,702 MMBtu for the same
quarter in 1996.  Interest income for the quarter ended March 31, 1997 was
$12,186 compared to $23,980 for the same quarter in 1996.  General and
administrative expenses during the first quarter of 1997 amounted to $187,134
compared to $159,457 for the same quarter in 1996.

     Distributable income for the quarter ended March 31, 1997 was $3,928,866 or
$.41 per Unit compared to $6,393,566 or $.66 per Unit for the first quarter of
1996.  This decrease was the result of adjustments resulting from expansion of
federal units within the Underlying Properties.  A distribution of $.408865 per
Unit was made on February 28, 1997 to Unitholders of record on February 14,
1997.

     Because the Trust incurs administrative expenses throughout a quarter but
receives its royalty income only once in a quarter, the Trustee established in
the first quarter of 1993 a cash reserve for the payment of expenses and
liabilities of the Trust.  The Trustee thereafter has adjusted the amount of
such reserve in certain quarters as required for the payment of the Trust's
expenses and liabilities, in accordance with the provisions of the Trust
Agreement.  The Trustee anticipates that it will maintain for the foreseeable
future a cash reserve which will fluctuate as expenses are paid and royalty
income is received.

     Royalty income to the Trust is attributable to the sale of depleting
assets.  All of the Underlying Properties burdened by the Royalty Interests
consist of producing properties.  Accordingly, the proved reserves attributable
to WPC's interest in the Underlying Properties are expected to decline
substantially during the term of the Trust and a portion of each cash
distribution made by the Trust will, therefore, be analogous to a return of
capital.  Accordingly, cash yields attributable to the Units are expected to
decline over the term of the Trust.

                                       12
<PAGE>
 
     Royalty income received by the Trust in a given calendar quarter will
generally reflect the sum of (i) proceeds from the sale of gas produced from the
WI Properties during the preceding calendar quarter, plus (ii) cash received by
WPC with respect to the Farmout Properties either (a) during the preceding
calendar quarter or (b) if received in sufficient time to be paid to the Trust,
in the month immediately following such calendar quarter.  Accordingly, the
royalty income included in distributable income for the quarter ended March 31,
1997 was based on production volumes and natural gas prices for the period
October 1996 through December 1996, as shown in the table below.  Due to delays
associated with the receipt of income related to the Farmout Properties, the
Trust's royalty income for the 1997 first quarter reflects estimated production
volumes from the Farmout Properties for the months of September 1996 through
November 1996, as shown in the table below.  The production volumes included in
the table below are for production attributable to the Underlying Properties,
and not for production attributable to the Trust's Royalty Interests and are net
of the amount of production attributable to WPC's royalty obligations to third
parties, which is determined by contractual arrangement with such parties.

     Production from the WI Properties is generally sold pursuant to a gas
purchase contract between WPC and WFS Gas Resources Company ("WFSGR") (as
successor in interest to Williams Gas Marketing Company).  The gas purchase
contract provides certain protections for WFSGR in the form of price credits
(for production purchased by WFSGR on or after January 1, 1994) and for
Unitholders when the applicable Blanco Hub Spot Price falls below $1.75 per
MMBtu and provides certain benefits for WFSGR when the Blanco Hub Spot Price
exceeds $2.00 per MMBtu.  The gas purchase contract also provides that the price
paid for gas by WFSGR is reduced by the amount of gathering, processing and
certain other costs paid by WFSGR.

                                       13
<PAGE>
 
     The Blanco Hub Spot Price was above $1.75 per MMBtu during January and
February 1997 and below $1.75 per MMBtu in March 1997.  However, pursuant to the
terms of the gas purchase contract, WFSGR continued to purchase gas produced
from the WI Properties at the $1.70 minimum purchase price, less certain
gathering, processing and delivery costs paid by WFSGR, established by the gas
purchase contract; and WFSGR received a price credit from WPC for each MMBtu of
natural gas so purchased by WFSGR equal to the difference between the $1.70
minimum purchase price and the applicable index price (which price is equal to
97 percent of the applicable Blanco Hub Spot Price).  WPC estimates that, as of
March 31, 1997, WFSGR had aggregate price credits of approximately $21.6 million
of which the Trust's 81 percent interest was approximately $17.5 million.  The
Blanco Hub Spot Price was below $1.75 per MMBtu in April 1997.

     The entitlement of WFSGR to recoup the price credits means that if and when
the applicable Blanco Hub Spot Price rises above $1.75 per MMBtu, future royalty
income paid to the Trust would be reduced until such time as such price credits
have been fully recouped.  Corresponding cash distributions to Unitholders would
also be reduced.

     The information in this Form 10-Q concerning production and prices relating
to the Underlying Properties is based on information prepared and furnished by
WPC to the Trustee.  The Trustee has no control over and no responsibility
relating to the operation of the Underlying Properties.

     This report on Form 10-Q includes "forward-looking statements" within the
meaning of Section 27A of the Securities Act of 1933, as amended, and Section
21E of the Securities Exchange Act of 1934, as amended.  All statements other

Although the Trustee believes that the expectations reflected in such forward-
looking statements are reasonable, it can give no assurance that such
expectations will prove to have been correct.
