The following information is subject to the detailed provisions of (i) the Trust
Agreement of Burlington Resources Coal Seam Gas Royalty Trust (the "Trust
Agreement"), dated as of May 1, 1993, among Burlington Resources Inc., a
Delaware corporation ("Burlington Resources"), Burlington Resources Oil & Gas
Co., a Delaware corporation ("BROG"), as grantor, Mellon Bank (DE) National
Association, a national banking association (the "Delaware Trustee"), and
NationsBank of Texas, N.A., a national banking association (the "Trustee"), as
trustees, and (ii) the Net Profits Interest Conveyance (the "Conveyance") dated
effective as of May 1, 1993 from BROG to the Trust. Effective January 1, 1996,
MOPI was merged with and into Meridian Oil Inc. ("MOI"), a wholly owned
subsidiary of Burlington Resources. Effective July 11, 1996, MOI changed its
name to Burlington Resources Oil & Gas Company ("BROG") and Meridian Oil Trading
Inc. ("MOTI") and Meridian Oil Gathering Inc. ("MOGI"), both affiliates of MOI,
changed their names to Burlington Resources Trading Inc. ("BRTI") and Burlington
Resources Gathering Inc. ("BRGI"), respectively. Accordingly, in this Form 10-K
references prior to the date of such merger to BROG refer to MOPI, references to
BRTI refer to MOTI and references to BRGI refer to MOGI. Copies of the Trust
Agreement and of the Conveyance are filed as exhibits to this Form 10-K. The
provisions governing the Trust are complex and extensive and no attempt has been
made below to describe or reference all of such provisions. The following is a
general description of the basic framework of the Trust and a summary of the
material terms of the Trust Agreement, and detailed provisions concerning the
Trust may be found in the Trust Agreement.

CREATION AND ORGANIZATION OF THE TRUST

     All of the authorized units of beneficial interest in the Trust ("Units")
were issued to BROG on June 17, 1993. On that date, BROG transferred its Units
to its parent, Burlington Resources, by dividend. Burlington Resources, in turn,
sold, by means of a prospectus dated June 10, 1993, 7,700,000 Units on June 17,
1993, and an additional 1,100,000 Units on June 23, 1993, to the public through
various underwriters (the "Public Offering").

     The Trust has been formed under Delaware law pursuant to the terms of the
Trust Agreement to acquire and hold certain net profits interests (the "Royalty
Interests") in BROG's interest in the Fruitland coal formation underlying the
Northeast Blanco Unit (the "Underlying Properties"). The Royalty Interests were
conveyed to the Trust on June 17, 1993 pursuant to the Conveyance for the
benefit of the Unitholders. The Trustee has all powers to collect and distribute
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 or
are required by law 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. Neither BROG nor the
operator of the Underlying Properties has any contractual commitments to the
Trust to further develop the Underlying Properties, to remain as operator with
respect to the Northeast Blanco Unit or to maintain its ownership interest in
any of the properties. However, after the conveyance of the Royalty Interests,
BROG retained its interest in the Underlying Properties, which interest is
burdened by the Royalty Interests. BROG may sell its interest in the Underlying
Properties subject to and burdened by the Royalty Interests. For a description
of the Underlying Properties and other information relating to such properties,
see "Item 2 -- The Royalty Interests."

     The Delaware Trustee and the Trustee may resign at any time upon 60 days'
prior written notice or be removed with or without cause at any time by a vote
of a majority of the outstanding Units, provided in each
                                        5
<PAGE>   9

case that a successor trustee has been appointed and has accepted its
appointment. Any successor trustee must be a bank or trust company meeting
certain requirements including having combined capital, surplus and undivided
profits of at least $20,000,000, in the case of the Delaware Trustee, and
$100,000,000, in the case of the Trustee.

ASSETS OF THE TRUST

     The only assets of the Trust, other than cash and temporary investments
being held for the payment of expenses and liabilities and for distribution to
Unitholders, are the Royalty Interests. The Royalty Interests consist primarily
of a net profits interest (the "NPI") in the Underlying Properties, generally
entitling the Trust to receive 95 percent of the NPI Net Proceeds. "NPI Net
Proceeds" consists generally of the aggregate proceeds attributable to BROG's
net revenue interest in the Underlying Properties (other than its interest by
virtue of Infill Wells, as defined below) based on the sale at the Central
Gathering Point (as defined) of gas produced from the Underlying Properties,
less (i) BROG's working interest share of property, production and related taxes
(including severance taxes) on the Underlying Properties; (ii) BROG's working
interest share of lease operating expenses on the Underlying Properties; (iii)
BROG's working interest share of capital costs on the Underlying Properties
(other than capital costs incurred prior to January 1, 1994, which costs were
borne by BROG to the extent of its working interest share); (iv) royalties, if
any, required to be paid that are based on the value of Section 29 tax credits
attributable to such working interest share; and (v) interest on the unrecovered
portion, if any, of the foregoing costs at Citibank's Base Rate. The Royalty
Interests also include a net profits interest (the "Infill NPI") entitling the
Trust to receive a 20 percent interest in the Infill Net Proceeds, as defined
below, from the sale of production from any additional wells drilled on the
Underlying Properties after May 1, 1993 pursuant to a change in spacing rules or
a change allowing additional wells to be drilled on a spacing or proration unit
("Infill Wells"). "Infill Net Proceeds" consists generally of the aggregate
proceeds based on the price at the Central Gathering Point of gas attributable
to BROG's interest in any Infill Wells less BROG's working interest share of
taxes, lease operating expenses, capital costs, and interest on the unrecovered
portion, if any, of the foregoing costs. See "Item 2 -- The Royalty Interests"
for more information.

LIABILITIES OF THE TRUST

     Because of the passive nature of the Trust assets and the restrictions on
the activities of the Trustee, it is anticipated that the only liabilities the
Trust will incur are those for routine administrative expenses, such as the
trustees' fees and accounting, engineering, legal and other professional fees
and the administrative services fee paid to Burlington Resources. However, as
discussed under "-- Federal Income Taxation," if a court were to hold that the
Trust is taxable as a corporation, then the Trust would be subject to Federal
income taxes.

DUTIES AND LIMITED POWERS OF THE TRUSTEE

     Under the Trust Agreement, the Trustee receives the payments attributable
to the Royalty Interests and pays all expenses, liabilities and obligations of
the Trust. With respect to any liability that is contingent or uncertain in
amount or that otherwise is not currently due and payable, the Trustee has the
discretion to establish a cash reserve for the payment of such liability. The
Trustee is entitled to cause the Trust to borrow money to pay expenses,
liabilities and obligations that cannot be paid out of cash held by the Trust.
Any such borrowing may be from any source, including from the entity serving as
Trustee or Delaware Trustee, provided that the entity serving as Trustee or
Delaware Trustee shall not be obligated to lend to the Trust. To secure payment
of any such indebtedness (including any indebtedness to the entity serving as
Trustee or Delaware Trustee), the Trustee is authorized to (i) mortgage and
otherwise encumber the entire Trust estate or any portion thereof, including the
Royalty Interests; (ii) carve out and convey production payments; (iii) include
all terms, powers, remedies, covenants and provisions it deems necessary or
advisable, including confession of judgment and the power of sale with or
without judicial proceedings; and (iv) provide for the exercise of those and
other remedies available to a secured lender in the event of a default on such
loan. The terms of such indebtedness and security interest, if funds were loaned
by the entity serving as Trustee or Delaware Trustee, must be similar to the
terms which such entity would grant to a similarly situated commercial customer
with

                                        6
<PAGE>   10

whom it did not have a fiduciary relationship, and such entity shall be entitled
to enforce its rights with respect to any such indebtedness and security
interest as if it were not then serving as trustee.

     The Trustee is authorized and directed to sell and convey the Royalty
Interests without Unitholder approval in certain instances as described in the
Trust Agreement, including upon termination of the Trust. The Trustee is
empowered by the Trust Agreement to employ consultants and agents (including
BROG and Burlington Resources) and to make payments of all fees for services or
expenses out of the assets of the Trust. The Trust has no employees. The
administrative functions of the Trust are performed by the Trustee.

     The Trust Agreement authorizes the Trustee to take such action as in its
judgment is necessary or advisable to achieve the purposes of the Trust. The
Trustee is authorized to agree to modifications of the terms of the Conveyance
and to settle disputes with respect thereto, so long as such modifications or
settlements do not result in treatment of the Trust for Federal income tax
purposes as an association taxable as a corporation and such modifications or
settlements do not alter the nature of the Royalty Interests as a right to
receive a share of production or the proceeds of production from the Underlying
Properties which, with respect to the Trust, are free of any operating rights,
expenses or obligations. The Trust Agreement provides that cash being held by
the Trustee as a reserve for liabilities or for distribution at the next
distribution date will be placed in demand accounts, U.S. government
obligations, repurchase agreements secured by such obligations, or certificates
of deposit, but the Trustee is otherwise prohibited from acquiring any asset
other than the initial cash deposit and the Royalty Interests or engaging in any
business or investment activity of any kind whatsoever. The Trustee may deposit
funds awaiting distribution in an account with the Trustee or Delaware Trustee
provided the interest paid equals the amount paid by the Trustee or Delaware
Trustee, as the case may be, on similar deposits.

LIABILITIES OF THE DELAWARE TRUSTEE AND THE TRUSTEE

     Each of the Delaware Trustee and the Trustee may act in its discretion and
shall be personally or individually liable only for fraud or acts or omissions
in bad faith or which constitute gross negligence (and for taxes, fees and other
charges based on any fees, commissions or compensation received pursuant to the
Trust Agreement) and will not be otherwise liable for any act or omission of any
agent or employee unless such trustee has acted in bad faith or with gross
negligence in the selection or retention of such agent or employee. Each of the
Delaware Trustee and the Trustee (and their respective agents) is indemnified by
Burlington Resources and BROG and from the Trust assets for certain
environmental liabilities, and for any other liability, expense, claim, damage
or other loss incurred in performing its duties, unless resulting from gross
negligence, fraud or bad faith (each of the Delaware Trustee and the Trustee
being indemnified from the Trust assets against its own negligence which does
not constitute gross negligence), and will have a first lien against the assets
of the Trust as security for such indemnification and for reimbursements and
compensation to which it is entitled, provided that the Trustee and the Delaware
Trustee are generally required to first be indemnified from Trust assets before
seeking indemnification from Burlington Resources. Burlington Resources has also
indemnified the Trustee and the Delaware Trustee against certain securities laws
liabilities. Neither the Delaware Trustee nor the Trustee is entitled to
indemnification from Unitholders (except in connection with lost or destroyed
Unit certificates).

TERMINATION AND LIQUIDATION OF THE TRUST

     The Trust will not terminate prior to January 1, 2003, except upon the
affirmative vote of the holders of not less than 66 2/3% percent of the
outstanding Units to liquidate the Trust. Thereafter, and subject to Burlington
Resources' conditional right of repurchase (see "-- Description of
Units -- Conditional Right of Repurchase"), the Trust will terminate upon the
first to occur (such date, the "Termination Date") of (i) an affirmative vote of
the holders of not less than 66 2/3% percent of the outstanding Units to
terminate the Trust; (ii) such time as the ratio of the cash amounts received by
the Trust from the Royalty Interests (excluding deductions for capital
expenditures) to administrative costs of the Trust is less than 1.2 to 1.0 for
three consecutive quarters; (iii) such time as the Royalty Interests held by the
Trust have been sold by the Trust; (iv) March 1 of any calendar year if, based
on a reserve report as of December 31 of the prior year, it is determined that,
as of such date, the net present value (discounted at 10 percent) of the
estimated future net
                                        7
<PAGE>   11

revenues (calculated in accordance with criteria established by the Securities
and Exchange Commission (the "Commission") except that such calculation will
utilize as the gas price in such calculation the average monthly gas price
(before deduction of costs) paid under the Gas Purchase Contract for production
attributable to BROG's interest in the Underlying Properties during the 12
months ending on such December 31) of proved reserves attributable to the
Royalty Interests is equal to or less than $30 million; and (v) December 31,
2012. Following termination, the Trustee and the Delaware Trustee will continue
to act as trustees of the Trust until all remaining Trust assets have been sold
and the net proceeds from such sales distributed to Unitholders.

     Upon the termination of the Trust, the Trustee will use its best efforts
(as defined in the Trust Agreement) to sell any remaining Royalty Interests for
cash pursuant to the procedures described herein. The Trustee will retain an
investment banking firm (the "Advisor") on behalf of the Trust who will assist
the Trustee in selling the remaining Royalty Interests then owned by the Trust.
BROG has the right, but not the obligation, to purchase all remaining Royalty
Interests following termination of the Trust as described in the following
paragraph.

     BROG may, within 60 days following the Termination Date, make a cash offer
to purchase all of the remaining Royalty Interests then held by the Trust. In
the event such an offer is made by BROG, the Trustee will decide, based on the
recommendation of the Advisor, to either (i) accept such offer (in which case no
sale to BROG will be made unless a fairness opinion is given by the Advisor that
the purchase price is fair to the Unitholders) or (ii) defer action on the offer
for approximately 60 days and seek to locate other buyers for the remaining
Royalty Interests. If the Trustee defers action on BROG's offer, the offer will
be deemed withdrawn and the Trustee will then use best efforts (as defined in
the Trust Agreement), assisted by the Advisor, to locate other buyers for the
Royalty Interests. At the end of a 120-day period following the Termination
Date, the Trustee is required to notify BROG of the highest of any other offers
acceptable to the Trustee (which must be an all cash offer) received during such
period (the "Highest Offer Price"). BROG then has the right (whether or not it
made an initial offer), but not the obligation, to purchase all remaining
Royalty Interests for a cash purchase price computed as follows: (i) if the
Highest Offer Price is more than 105 percent of BROG's original offer (or if
BROG did not make an initial offer), the purchase price will be 105 percent of
the Highest Offer Price, or (ii) if the Highest Offer Price is equal to or less
than 105 percent of BROG's original offer, the purchase price will be equal to
the Highest Offer Price. If no other acceptable offers are received for all
remaining Royalty Interests, the Trustee may request BROG to submit another
offer for consideration by the Trustee and may accept or reject such offer.

     If a sale of the Royalty Interests is made or a definitive contract for
sale of the Royalty Interests is entered into within a 150-day period following
the Termination Date, the buyer of the Royalty Interests, and not the Trust or
Unitholders, will be entitled to all proceeds of production attributable to the
Royalty Interests following the Termination Date.

     In the event that BROG does not purchase the Royalty Interests, the Trustee
may accept any offer for all or any part of the Royalty Interests as it deems to
be in the best interests of the Trust and Unitholders and may continue, for up
to one calendar year after the Termination Date, to attempt to locate a buyer or
buyers of the remaining Royalty Interests in order to sell such interests in an
orderly fashion. If any Royalty Interests have not been sold or a definitive
agreement for sale has not been entered into by the end of such calendar year,
the Trustee is required to sell the remaining Royalty Interests at public
auction, which sale may be to BROG or any of its affiliates.

     BROG's purchase rights, as described, may be exercised by BROG and each of
its successors in interest and assigns. BROG's purchase rights are fully
assignable by BROG to any person or entity. The costs of liquidation, including
the fees and expenses of the Advisor, and the Trustee's liquidation fee will be
paid by the Trust. Unitholders are not entitled to any rights of appraisal or
similar rights in connection with the termination of the Trust.

ARBITRATION AND DERIVATIVE ACTIONS

     Pursuant to the Trust Agreement, any dispute, controversy or claim that may
arise between or among (i) Burlington Resources or BROG, on the one hand, and
the Trustee, the Delaware Trustee and the Trust, on the other hand, in
connection with or otherwise relating to the Trust Agreement or the application,
implementation, validity or breach of the Trust Agreement or any provision
thereof or (ii) BROG, on the one hand, and the Trust, on the other hand, in
connection with or otherwise relating to the Conveyance or the application,
implementation, validity or breach of the Conveyance or any provision thereof,
shall be finally, conclusively and exclusively settled by final and binding
arbitration in Houston, Texas in accordance with the Rules of Practice and
Procedure for the arbitration of commercial disputes of Judicial Arbitration &
Mediation Services, Inc. (or any successor thereto) then in effect. The Gas
Purchase Contract also includes a provision that will require BROG and BRTI to
submit any dispute regarding such contract to alternative dispute resolution
before litigating such matter.

     The procedures for the arbitration of disputes enumerated in the Trust
Agreement neither bar nor restrict the statutory right of any Unitholder under
Section 3816 of the Delaware Code to bring a derivative action. Pursuant to
Section 3816 of the Delaware Code, a derivative action in the right of the Trust
may be brought by a Unitholder in the Delaware Court of Chancery against
Burlington Resources or BROG (or any other person) to recover a judgment in
favor of the Trust if the Trustee has refused to bring such action or if an
effort to cause the Trustee to bring such action is not likely to succeed.

     Pursuant to Section 3816 of the Delaware Code, a plaintiff in a derivative
action must be a beneficial owner at the time such action is brought and (a) at
the time of the transaction subject to such complaint or (b) the plaintiff's
status as a beneficial owner must have devolved upon it by operation of law or
pursuant to the terms of the governing instrument of the trust from a person or
entity who was a beneficial owner at the time of the transaction giving rise to
the complaint. If a derivative action is successful, in whole or in part, or if
anything is received by the trust as a result of a judgment, compromise or
settlement of any such action, the Delaware Chancery Court may award the
plaintiff reasonable expenses, including reasonable attorney's fees. If any
award is so received by the plaintiff, the Delaware Chancery Court shall make
such award of the plaintiff's expenses payable out of those proceeds and direct
plaintiff to remit to the trust the remainder thereof. If the proceeds are
insufficient to reimburse plaintiff's reasonable expenses in bringing the
derivative action, the Delaware Chancery Court may direct that any such award of
plaintiff's expenses or a portion thereof be paid by the trust. In addition,
under Section 3816 a beneficial owner's right to bring a derivative action may
be subject to such additional standards and restrictions, if any, as are set
forth in the governing instrument of the trust, including, without limitation,
the requirement that beneficial owners owning a specified beneficial interest in
the trust join in the bringing of the derivative action. The rights of the
Unitholders to bring a derivative action on behalf of the Trust provided
pursuant to Section 3816 of the Delaware Code are substantially similar to the
derivative rights afforded stockholders under Section 327 of Chapter 8 of the
Delaware General Corporation Law and applicable Delaware case law.

     Despite the latitude afforded pursuant to Section 3816, the Trust Agreement
does not impose any such additional standards or restrictions on a Unitholder
with respect to its right to bring a derivative action (other than as discussed
below with respect to "BROG Payment Obligations" and "BRTI Payment Obligations"
(as such terms are defined herein)). In the event that any Unitholder was
successful in bringing a derivative action on behalf of the Trust to enforce
rights on behalf of the Trust against Burlington Resources or BROG, then such
Unitholder could, on behalf of the Trust, pursue such rights against Burlington
Resources or BROG, as the case may be, in the Delaware Chancery Court. The Trust
Agreement does not require, and expressly provides that it shall not be
construed to require, arbitration of a claim or dispute solely between the
Trustee and the Delaware Trustee or of any claim or dispute brought by any
person or entity, including, without limitation, any Unitholder (whether in its
own right or through a derivative action in the right of the Trust), who is not
a party to the Trust Agreement.

     The right of a Unitholder to bring a derivative action on behalf of the
Trust with respect to Burlington Resources' obligation to cure any deficiency in
BROG Payment Obligations or BRTI Payment Obligations is subject to the
restriction that such right may only be exercised by Unitholders owning of
record not less than

                                        9
<PAGE>   13

25 percent of the Units then outstanding (treated as a single class) and then
only absent action by the Trustee to enforce any such obligation within 10 days
following receipt by the Trustee of a written request served upon the Trustee by
such Unitholders to take such action. In such an event, Unitholders owning of
record not less than 25 percent of the Units then outstanding may, acting as a
single class and on behalf of the Trust, seek to enforce such obligations.

                              DESCRIPTION OF UNITS

     Each Unit represents an equal undivided share of beneficial interest in the
Trust and is evidenced by a transferable certificate issued by the Trustee. Each
Unit entitles its holder to the same rights as the holder of any other Unit, and
the Trust has no other authorized or outstanding class of equity security. At
March 13, 1998, there were 8,800,000 Units outstanding. The Trust may not issue
additional Units.

DISTRIBUTIONS AND INCOME COMPUTATIONS

     The Trustee determines for each quarter the amount of cash available for
distribution to Unitholders. Such amount (the "Quarterly Distribution Amount")
is equal to the excess, if any, of the cash received by the Trust, on or prior
to the last business day before the 50th day following the end of each calendar
quarter ending prior to the dissolution of the Trust from the Royalty Interests
then held by the Trust attributable to production during such quarter, plus,
with certain exceptions, any other cash receipts of the Trust during such
quarter (which might include sales proceeds not sufficient in amount to qualify
for special distribution (as described in the next paragraph) and interest),
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. Based on the payment procedures relating to the Royalty Interests, cash
received by the Trustee in a particular quarter from the Royalty Interests
generally represents proceeds from the sale of gas produced during the preceding
calendar quarter. The Quarterly Distribution Amount for each quarter is payable
to Unitholders of record on the 63rd day following the end of such calendar
quarter unless such day is not a business day in which case the record date will
be the next business day thereafter. The Trustee distributes the Quarterly
Distribution Amount on or prior to 75 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 Quarterly
Distribution Amount from the date of receipt thereof by the Trustee to the
payment date.

     The Royalty Interests may be sold under certain circumstances and will be
sold following termination of the Trust. Any proceeds from sales of the Royalty
Interests, less liabilities and expenses of the Trust and amounts used for cash
reserves, will be distributed, together with any interest expected to be earned
thereon, to Unitholders of record on the record date established for such
distribution. A special distribution will be made of undistributed sales
proceeds and other amounts received by the Trust aggregating in excess of
$10,000,000 (a "Special Distribution Amount"). 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 will be made no later than 15 days after the Special Distribution
Amount record date.

     The terms of the Trust Agreement seek to assure to the extent practicable
that gross income attributable to cash being distributed will be reported by the
Unitholder who receives such distributions assuming that such Unitholder is the
owner of record on the applicable record date. In certain circumstances,
however, a Unitholder will not receive the cash giving rise to such income. For
example, the Trustee maintains a cash reserve, and is authorized to borrow money
under certain conditions, in order to pay or provide for the payment of Trust
liabilities. Income associated with the cash used to increase that reserve or to
repay any such borrowing must be reported by the Unitholder, even though that
cash is not distributed to him. Likewise, if a portion of a cash distribution is
attributable to a reduction in the cash reserve maintained by the Trustee, such

                                       10
<PAGE>   14

cash is treated as a reduction to the Unitholder's basis in his Units and is not
treated as taxable income to such Unitholder (assuming such Unitholder's basis
exceeds the amount of the distribution of cash reserve).

CONDITIONAL RIGHT OF REPURCHASE

     Burlington Resources and any of its successors and affiliates retain in the
Trust Agreement the right to repurchase all (but not less than all) outstanding
Units at any time at which 15 percent or less of the outstanding Units is owned
by persons or entities other than Burlington Resources and its affiliates.
Subject to the following sentence, any such repurchase would be at a price equal
to the greater of (i) the highest price at which Burlington Resources or any of
its affiliates acquired Units during the 90 days immediately preceding the date
(the "Determination Date") which is three New York Stock Exchange trading days
prior to the date on which notice of such exercise is delivered to Unitholders
and (ii) the average closing price of Units on the New York Stock Exchange for
the 30 trading days immediately preceding the Determination Date. If Burlington
Resources or any of its affiliates acquires Units (other than an acquisition
from Burlington Resources or any affiliate) during the period that is three
trading days after the Determination Date at a price per Unit greater than that
at which an acquisition was made during the 90-day period referred to in clause
(i) of the preceding sentence, then for purposes of clause (i) of the preceding
sentence the highest price used therein shall be such greater price. Any such
repurchase would be conducted in accordance with applicable Federal and state
securities laws.

     In the event that Burlington Resources elects to purchase all Units,
Burlington Resources and the Trustee will, prior to the date fixed for purchase,
give all Unitholders of record not less than 15 days' nor more than 60 days'
written notice specifying the time and place of such repurchase, calling upon
each such Unitholder to surrender to Burlington Resources on the repurchase date
at the place designated in such notice its certificate or certificates
representing the number of Units specified in such notice of repurchase. On or
after the repurchase date, each holder of Units to be repurchased must present
and surrender its certificates for such Units to Burlington Resources at the
place designated in such notice and thereupon the purchase price of such Units
shall be paid to or on the order of the person or entity whose name appears on
such certificate or certificates as the owner thereof. In no event may fewer
than all of the outstanding Units represented by the certificates be repurchased
(except for any Units held by Burlington Resources and any of its affiliates).

     If Burlington Resources and the Trustee give a notice of repurchase and if,
on or before the date fixed for repurchase, the funds necessary for such
repurchase shall have been set aside by Burlington Resources, separate and apart
from its other funds, in trust for the pro rata benefit of the holders of the
Units so noticed for repurchase then, notwithstanding that any certificate for
such Units has not been surrendered, at the close of business on the repurchase
date the holders of such Units shall cease to be Unitholders and shall have no
interest in or claims against Burlington Resources, BROG, the Trust, the
Delaware Trustee or the Trustee by virtue thereof and shall have no voting or
other rights with respect to such Units, except the right to receive the
purchase price payable upon such repurchase, without interest thereon and
without any other distributions for record dates after the date of notice of the
repurchase, upon surrender (and endorsement, if required by Burlington
Resources) of their certificates, and the Units evidenced thereby shall no
longer be held of record in the names of such Unitholders. Subject to applicable
escheat laws, any monies so set aside by Burlington Resources and unclaimed at
the end of two years from the repurchase date shall revert to the general funds
of Burlington Resources, after which reversion the holders of such Units so
noticed for repurchase could look only to the general funds of Burlington
Resources for the payment of the purchase price. Any interest accrued on funds
so deposited would be paid to Burlington Resources from time to time as
requested by Burlington Resources.

     In the event that Burlington Resources exercises and consummates its right
of repurchase, then at its option it may cause the Trust to be terminated by
providing written notice thereof to the Trustee and the Delaware Trustee. Within
30 days following written notice of Burlington Resources' decision to terminate
the Trust, the Trustee and the Delaware Trustee must cause all Royalty Interests
(and, subject to the rights of Unitholders with respect to the receipt of
distributions for which a record date has been determined, all proceeds of
production attributable to the Royalty Interests) and any other assets of the
Trust to be conveyed

                                       11
<PAGE>   15

to Burlington Resources or its assignee (subject to the right of such trustees
to create reasonable reserves in connection with the liquidation of the Trust).

POSSIBLE DIVESTITURE OF UNITS

     The Trust Agreement imposes no restrictions based on nationality or other
status of Unitholders. However, the Trust Agreement provides that in the event
of certain judicial or administrative proceedings seeking the cancellation or
forfeiture of any property in which the Trust has an interest, or asserting the
invalidity of or otherwise challenging any portion of the Royalty Interests,
because of the nationality, citizenship or any other status of any one or more
Unitholders, the Trustee will give written notice thereof to each Unitholder
whose nationality, citizenship or other status is an issue in the proceeding,
which notice will constitute a demand that such Unitholder dispose of his Units
within 30 days. If any Unitholder fails to dispose of his Units within 90 days
after expiration of the 30 day period, the Trustee shall cancel all outstanding
certificates issued in the name of such Unitholder, transfer all Units held by
such Unitholder to the Trustee and sell such Units (including by private sale).
The proceeds of such sale (net of sales expenses), pending delivery of
certificates representing the Units, will be held by the Trustee in a
non-interest-bearing escrow account for the benefit of the Unitholder and will
be paid to the Unitholder upon surrender of such certificates. Cash
distributions payable to such Unitholder will also be held in a
non-interest-bearing escrow account pending disposition by the Unitholder of the
Units or cancellation of certificates representing the Units by the Trustee.

PERIODIC REPORTS TO UNITHOLDERS

     Within 75 days following the end of each of the first three calendar
quarters of each calendar year, the Trustee mails to each person or entity who
was a Unitholder of record (i) on the quarterly record date for such quarter or
(ii) on each Special Distribution Amount record date occurring during such
quarter, a report which shows in reasonable detail the assets and liabilities
and receipts and disbursements of the Trust and the revenues and direct
operating expenses of BROG's interest in the Underlying Properties for such
quarter. Within 120 days following the end of each fiscal year or such shorter
period of time as may be required by the rules of the New York Stock Exchange,
the Trustee mails to Unitholders of record as of a date to be selected by the
Trustee an annual report containing audited financial statements relating to the
Trust and BROG's interest in the Underlying Properties.

     The Trustee files such returns for Federal income tax purposes as it is
required to comply with applicable law. The Trustee mails to each person or
entity who was a Unitholder of record (i) on the quarterly record date for such
quarter or (ii) on each Special Distribution Amount record date occurring during
such quarter, a report which shows in reasonable detail the information
necessary to permit each Unitholder to make all calculations reasonably
necessary for tax purposes. The Trustee treats all income, credits and
deductions recognized during each calendar quarter during the term of the Trust
as having been recognized by holders of record on the quarterly record date
established for the distribution unless otherwise advised by counsel. Available
year-end tax information permitting each Unitholder to make all calculations
reasonably necessary for tax purposes is distributed by the Trustee to
Unitholders no later than March 15 of the following year.

     Each Unitholder and his duly authorized agents and attorneys have the right
during reasonable business hours upon reasonable prior notice to examine and
inspect records of the Trust, the Trustee and the Delaware Trustee.

VOTING RIGHTS OF UNITHOLDERS

     While Unitholders have certain voting rights as provided in the Trust
Agreement, such rights differ from and are more limited than those of
stockholders of a corporation. For example, there is no requirement for annual
meetings of Unitholders or for annual or other periodic re-election of the
Trustee or the Delaware Trustee.

     Meetings of Unitholders may be called by the Trustee or by Unitholders
owning not less than 10 percent in number of the outstanding Units. All such
meetings shall be held in Houston, Texas and written notice of
                                       12
<PAGE>   16

every such meeting setting forth the time and place of the meeting and the
matters proposed to be acted upon shall be given not more than 60 nor less than
20 days before such meeting. The presence in person or by proxy of Unitholders
representing a majority of the outstanding Units is necessary to constitute a
quorum. Unitholders have the right to vote at all meetings of Unitholders and
each Unitholder shall be entitled to one vote for each Unit owned by such
Unitholder. The Trustee will call such meetings to consider amendments, waivers,
consents and other changes relating to the Gas Purchase Contract, the Gas
Gathering Contract or the Conveyance, if requested in writing by BROG. No matter
other than that stated in the notice of the Unitholder meeting shall be voted on
and no action by the Unitholders may be taken without a meeting.

     Generally, amendments to the Trust Agreement require approval of a majority
of the outstanding Units (except that amendment of required voting percentages
requires approval of at least 80 percent of the outstanding Units), but no
provision of the Trust Agreement may be amended that would (i) increase the
power of the Delaware Trustee or the Trustee to engage in business or investment
activities or (ii) alter the rights of the Unitholders as among themselves.
Without the written consent of Burlington Resources and the approval of not less
than 66 2/3% percent of the outstanding Units, no provision of the Trust
Agreement may be amended with respect to (a) the sale or disposition of all or
any part of the Trust estate, including the Royalty Interests, except as
specifically provided in the Trust Agreement, (b) termination of the Trust and
the disposition of Trust assets upon liquidation of the Trust or (c) BROG's
right of first refusal with respect to purchase of any remaining Royalty
Interests upon termination of the Trust. Without the written consent of
Burlington Resources and the approval of a majority of the outstanding Units, no
amendment may be made to the Trust Agreement that would alter Burlington
Resources' conditional right to repurchase all outstanding Units at any time at
which 15 percent or less of the outstanding Units is owned by persons or
entities other than Burlington Resources and its affiliates. Additionally, any
amendment that increases the obligations, duties or liabilities of or affects
the rights of the Delaware Trustee or the Trustee must be consented to by such
entity. The Trustee, the Delaware Trustee, Burlington Resources and BROG may,
without approval of the Unitholders, from time to time supplement or amend the
Trust Agreement in order to cure any ambiguity or to correct or supplement any
defective or inconsistent provisions, provided such supplement or amendment is
not adverse to the interests of the Unitholders. In addition, Burlington
Resources may direct the Trustee to change the name of the Trust without
approval of the Unitholders. Removal of the Trustee and the Delaware Trustee,
approval of amendments, waivers, consents and other changes relating to the Gas
Purchase Contract, the Gas Gathering Contract and the Conveyance, and the
approval of the merger or consolidation of the Trust into one or more entities
require approval of a majority of the outstanding Units. Except as set forth
under "-- Description of the Trust -- Termination and Liquidation of the Trust,"
all other actions may be approved by a majority vote of the Units represented at
a meeting at which a quorum is present or represented.

LIABILITY OF UNITHOLDERS

     Consistent with Delaware law, the Trust Agreement provides that the
Unitholders will have the same limitation on personal liability as is accorded
under the laws of such state to stockholders of a corporation for profit. No
assurance can be given, however, that the courts in jurisdictions outside of
Delaware will give effect to such limitation.

TRANSFER AGENT

     The Trustee has appointed Boston Equiserve Shareholder Service transfer
agent and registrar for the Units (the "Transfer Agent").

                            FEDERAL INCOME TAXATION

     THE TAX CONSEQUENCES TO A UNITHOLDER OF THE OWNERSHIP AND SALE OF UNITS
WILL DEPEND IN PART ON THE UNITHOLDER'S TAX CIRCUMSTANCES. EACH UNITHOLDER
SHOULD THEREFORE CONSULT THE UNITHOLDER'S TAX ADVISOR ABOUT THE FEDERAL, STATE
AND LOCAL TAX CONSEQUENCES TO THE UNITHOLDER OF THE OWNERSHIP OF UNITS.

     The sections entitled "Federal Income Tax Consequences" and "Risk
Factors -- Risks Associated With the Units -- Tax Considerations" appearing in
the Prospectus (the "Public Offering Prospectus") dated June 10, 1993, which
constitutes a part of the Registration Statement on Form S-3 of Burlington
Resources (Registration No. 33-61164) filed in connection with the registration
of the Units under the Securities Act of 1933 for offer and sale in the Public
Offering, set forth, respectively, a summary of Federal income tax matters of
general application that addresses all material tax consequences of the
ownership and sale of the Units acquired in the Public Offering and a discussion
of certain risk factors associated with matters of Federal income taxation as
applied to the Trust and such Unitholders. A copy of such sections of the Public
Offering Prospectus is filed as an exhibit to this Form 10-K.

     In connection with the registration of the Units for offer and sale in the
Public Offering, Burlington Resources and the underwriters of the Units received
certain opinions of counsel to Burlington Resources (upon which the Trustee and
the Delaware Trustee were entitled to rely), including, without limitation,
opinions as to the material Federal income tax consequences of the ownership and
sale of the Units acquired in the Public Offering. The opinions of counsel to
Burlington Resources as to such Federal income tax consequences were based on
provisions of the Internal Revenue Code of 1986, as amended (the "IRC"), as of
June 17, 1993, the date of the closing of the Public Offering, existing and
proposed regulations thereunder and administrative rulings and court decisions
as of June 17, 1993, all of which are subject to changes that may or may not be
retroactively applied. Some of the applicable provisions of the IRC have not
been interpreted by the courts or the Internal Revenue Service ("IRS"). In
addition, such opinions of counsel to Burlington Resources were based on various
representations as to factual matters made by Burlington Resources and BROG in
connection with the Public Offering. As is typically the case, these opinions
were limited in their application to certain investors purchasing Units in the
Public Offering and, as a result, provide no assurance to investors purchasing
Units following the Public Offering.

     Neither counsel to the Trust, the Trustee nor the Delaware Trustee,
respectively, has rendered any opinions with respect to any tax matters
associated with the Trust or the Units.

     No ruling was requested by Burlington Resources, as the sponsor of the
Trust, from the IRS with respect to any matter affecting the Trust or
Unitholders. No assurance can be provided that the opinions of counsel to
Burlington Resources (which do not bind the IRS) will not be challenged by the
IRS or will be sustained by a court if so challenged.

SUMMARY OF CERTAIN FEDERAL INCOME TAX CONSEQUENCES

     The following summary of certain Federal income tax consequences of
acquiring, owning and disposing of Units is based on the opinions of counsel to
Burlington Resources on Federal income tax matters, which are set forth in the
Public Offering Prospectus, and is qualified in its entirety by express
reference to the sections of the Public Offering Prospectus identified in the
first paragraph of this "Federal Income Taxation" section. Although the Trust
believes that the following summary contains a description of all of the
material matters discussed in the opinions referenced above, the summary is not
exhaustive and many other provisions of the Federal tax laws may affect
individual Unitholders. Furthermore, the summary does not purport to be complete
or to address the tax issues potentially affecting Unitholders acquiring Units
other than by purchase through the Public Offering. Each Unitholder should
consult the Unitholder's tax advisor with respect to the effects of the
Unitholder's ownership of Units on the Unitholder's personal tax situation.

Classification and Taxation
of the Trust...............  The Trust will be treated as a grantor trust and
                             not as an association taxable as a corporation. As
                             a grantor trust, the Trust will not be subject to
                             Federal income tax. There can be no assurance that
                             the IRS will not challenge this treatment. The tax
                             treatment of the Trust and Unitholders could be
                             materially different if the IRS were to
                             successfully challenge this treatment.

Taxation of Unitholders....  Each Unitholder will be taxed directly on his
                             proportionate share of income, deductions, and
                             credits of the Trust attributable to the Royalty
                             Interests consistent with such Unitholder's taxable
                             year and method of

                                       14
<PAGE>   18

                             accounting, and without regard to the taxable year
                             or method of accounting employed by the Trust.

Income and Deductions......  The income of the Trust consists primarily of a
                             specified share of the proceeds from the sale of
                             coal seam gas produced from the Underlying
                             Properties. During 1997, the Trust earned interest
                             income on funds held for distribution and made
                             adjustments to the cash reserve maintained for the
                             payment of contingent or future obligations of the
                             Trust. The deductions of the Trust consist of
                             severance taxes and administrative expenses. In
                             addition, each Unitholder is entitled to depletion
                             deductions. See "Unitholder's Depletion Allowance"
                             below.

Limits on Deductions and
  Credits..................  Generally, a taxpayer is entitled to claim
                             deductions and tax credits generated by an
                             investment only if the investment has economic
                             substance. The application of this principle in the
                             context of the production and sale of
                             nonconventional fuels (like coal seam gas) which
                             generate the Section 29 tax credit is uncertain
                             because such application has not been addressed
                             either by a court or the IRS. An investment has
                             economic substance if the investor can demonstrate
                             that there is a reasonable possibility of deriving
                             an economic profit from the investment in excess of
                             a de minimis amount, apart from tax benefits. In
                             many cases, economic profit has been computed by
                             comparing the taxpayer's total cash investment to
                             the total cash reasonably expected to be received
                             by the taxpayer as a result of the investment. At
                             the time of the Public Offering, Burlington
                             Resources, after consultation with its counsel,
                             expressed its belief only in connection with the
                             Public Offering that the purchaser of a Unit in the
                             Public Offering, who did not borrow funds in order
                             to purchase his Unit, had a reasonable possibility
                             of deriving an economic profit in excess of a de
                             minimis amount apart from tax benefits associated
                             with ownership of the Unit. No assurance is given
                             either by the Trustee or counsel to the Trustee to
                             a purchaser of Units in or following the Public
                             Offering as to whether (and to what extent) such
                             purchaser will be entitled to claim deductions and
                             the Section 29 tax credit generated with respect to
                             such Units.

Section 29 Tax Credit......  Unitholders will be entitled, provided certain
                             requirements are met, to claim tax credits pursuant
                             to Section 29 of the IRC with respect to sales of
                             coal seam gas production attributable to the NPI,
                             the gross income from which is included in their
                             taxable income. The Section 29 tax credit provides
                             to a taxpayer a dollar-for-dollar reduction in his
                             regular Federal income tax liability, and,
                             therefore, generally provides to him a greater
                             benefit than a deduction which merely reduces the
                             amount of his taxable income. The Section 29 tax
                             credit applies to coal seam gas produced and sold
                             prior to January 1, 2003 from qualifying wells. For
                             a Unitholder who owned the same Units of record on
                             all four quarterly record dates during 1997, the
                             available Section 29 tax credit is approximately
                             $.826537 per Unit, based on the first estimate of
                             the GNP implicit price deflator published by the
                             Bureau of Economic Analysis.

                             The availability of Section 29 tax credits is
                             dependent upon meeting a number of requirements,
                             many of which are factual in nature. Burlington
                             Resources represented only in connection with the
                             Public Offering that those factual requirements
                             were met and Burlington Resources expressed its
                             belief in connection with the Public Offering that
                             substantially all of the production attributable to
                             the NPI from the coal seam gas wells
                                       15
<PAGE>   19

                             identified in the reserve estimate as of May 1,
                             1993, prepared by BROG in connection with the
                             Public Offering, qualified for Section 29 tax
                             credits. At the time of the Public Offering,
                             counsel to Burlington Resources opined as to those
                             requirements which are statutory or legal in
                             nature. If any of the factual requirements are not
                             met, or the opinion not followed, some or all of
                             the expected Section 29 tax credits may not be
                             available.

                             In addition, if the production units or
                             participating areas are expanded to include
                             additional production which does not qualify for
                             the Section 29 tax credit, the amount of Section 29
                             tax credits available to a Unitholder will be
                             reduced even though his share of production does
                             not diminish. Neither BROG nor the Trust can
                             control whether a production unit or participating
                             area is expanded.

                             No Section 29 tax credits will be available under
                             current law to a Unitholder with respect to
                             production attributable to the Infill NPI even if
                             an Infill Well recovers a portion of the reserves
                             that prior to the drilling and completion of an
                             Infill Well were recoverable from a well burdened
                             by the NPI that qualified for Section 29 tax
                             credits.

Limits on Unitholder's Use
of Credits.................  In any year, a Unitholder is permitted to reduce
                             his regular Federal income tax liability by the
                             Section 29 tax credits allocated to such Unitholder
                             for such year on a dollar-for-dollar basis, but
                             only to the extent such Unitholder's regular tax
                             liability exceeds his alternative minimum tax
                             liability (with certain adjustments). Any amount of
                             Section 29 tax credit in excess of a Unitholder's
                             total regular Federal income tax liability for a
                             year is permanently lost. Section 29 tax credits
                             cannot be used to reduce a Unitholder's liability
                             for any alternative minimum tax for any taxable
                             year but can be carried forward to reduce his
                             regular tax liability in a subsequent year (subject
                             to the applicable rules governing such
                             carryforward(s)).

Quarterly Allocations......  Under the IRC, a Unitholder is entitled to Section
                             29 tax credits only to the extent that he is an
                             owner of the economic interest at the time the coal
                             seam gas is produced. The Trustee allocates the
                             income received by the Trust for a quarter, and the
                             Section 29 tax credit allocable to such income, to
                             Unitholders of record on the quarterly record date
                             for such quarter. Such an allocation may be
                             challenged by the IRS, but any challenge is likely
                             to have a material adverse effect only if
                             successful and only for Unitholders who do not own
                             Units for a full quarter for each record date,
                             particularly Unitholders who acquire Units shortly
                             before a record date and sell shortly after a
                             record date.

Unitholder's Depletion
  Allowance................  Each Unitholder is entitled to amortize the cost of
                             the Units through cost depletion over the life of
                             the NPI (or if greater, through percentage
                             depletion equal to 15 percent of gross income). If
                             any portion of the NPI is treated as a production
                             payment or is not treated as an economic interest,
                             however, a Unitholder will not be entitled to
                             depletion in respect of such portion.

Non-Passive Activity
Income, Credits and Loss...  The income, credits and expenses of the Trust will
                             not be taken into account in computing the passive
                             activity losses and income under Section 469 of the
                             IRC for a Unitholder who acquires and holds Units
                             as

                                       16

                             an investment and did not acquire them in the
                             ordinary course of a trade or business. Section 29
                             tax credits generated by an investment in Units,
                             therefore, can be utilized to offset regular tax
                             liability on income from any source, whether active
                             or passive, subject to other limitations discussed
                             herein or arising from the individual tax
                             circumstances of each Unitholder. See "Limits on
                             Unitholder's Use of Credits" above.

Unitholder Reporting
  Information..............  The Trustee furnishes to Unitholders tax
                             information concerning royalty income, depletion
                             and the Section 29 tax credits on an annual basis.
                             Year-end tax information is furnished to
                             Unitholders no later than March 15 of the following
                             year. See the second paragraph under "Description
                             of Units -- Periodic Reports to Unitholders."

Tax Shelter Registration...  The Trust is registered as a "tax shelter" and its
                             tax shelter registration number is 93-147000231.
                             Issuance of a tax shelter registration number does
                             not indicate that the investment in Units or the
                             claimed tax benefits have been reviewed, examined
                             or approved by the IRS.

Substantial Understatement
  Penalty..................  Section 6662 of the IRC imposes a penalty in
                             certain circumstances for a substantial
                             understatement of taxes if a taxpayer's tax
                             liability is understated by more than the greater
                             of (a) 10 percent of the taxes required to be shown
                             on the return and (b) $5,000 ($10,000 for most
                             corporations). The penalty (which is not
                             deductible) is 20 percent of the understatement.

                             Except in the case of understatements attributable
                             to "tax shelter" items, which are subject to
                             special rules discussed below, an item of
                             understatement will not give rise to the penalty
                             if: (i) there is or was "substantial authority" for
                             the taxpayer's treatment of the item or (ii) all
                             the facts relevant to the tax treatment of the item
                             are adequately disclosed on the return or on a
                             statement attached to the return and there is a
                             reasonable basis for the tax treatment of such
                             item. In the case of Units, an individual
                             Unitholder may make adequate disclosure with
                             respect to particular tax items if certain
                             conditions are met. Special rules enacted in
                             December 1994 could affect the application of these
                             provisions with regard to a corporation acquiring
                             Units after December 8, 1994, to the extent such
                             provisions were found to apply to the ownership of
                             Units.

                             In the case of understatements attributable to "tax
                             shelter" items, the substantial understatement
                             penalty may be avoided only if the taxpayer
                             establishes that, in addition to having substantial
                             authority for his position, he reasonably believed
                             that the treatment claimed was more likely than not
                             the proper treatment of the item. A "tax shelter"
                             item is one that arises from a form of investment
                             if its principal purpose was the avoidance or
                             evasion of Federal income tax. Regulations
                             promulgated by the IRS indicate that an entity or
                             person has a principal purpose of avoidance or
                             evasion of Federal income tax if that purpose
                             "exceeds any other purpose." No assurance is given
                             either by the Trustee or counsel to the Trustee as
                             to the possible application of this penalty, in
                             part because such application depends largely upon
                             the individual circumstances under which the Units
                             were acquired. As a result, purchasers of Units in
                             and after the Public Offering should consult with
                             their personal tax advisors.

                              ERISA CONSIDERATIONS

     The section entitled "ERISA Considerations" appearing in the Public
Offering Prospectus sets forth certain information regarding the applicability
of the Employee Retirement Income Security Act of 1974, as amended, and the IRC
to pension, profit-sharing and other employee benefit plans, and is incorporated
herein by reference.

     Due to the complexity of the prohibited transaction rules and the penalties
imposed upon persons involved in prohibited transactions, it is important that
potential Qualified Plan investors consult with their counsel regarding the
consequences under ERISA and the IRC of their acquisition and ownership of
Units.

                            STATE TAX CONSIDERATIONS

     The following is intended as a brief summary of certain information
regarding state income taxes and other state tax matters affecting individuals
who are Unitholders. Unitholders are urged to consult their own legal and tax
advisors with respect to these matters.

     Unitholders should consider state and local tax consequences of holding
Units. The Trust owns Royalty Interests burdening gas properties located in New
Mexico. New Mexico has an income tax applicable to individuals. In addition to
any tax reporting and payment obligations of his state of residence, a
Unitholder is generally required to file state income tax returns and/or pay
taxes in New Mexico and may be subject to penalties for failure to comply with
such requirements. In addition, New Mexico in the future may require the Trust
to withhold tax from distributions to Unitholders. Unitholders should consult
their own tax advisors to determine their income tax filing requirements in New
Mexico with respect to their share of income of the Trust.

     The Trust has been structured to cause the Units to be treated for certain
state law purposes, including state taxation other than income taxation,
essentially the same as other securities, that is, as interests in intangible
personal property rather than as interests in real property. If the Units are
held to be real property or an interest in real property under the laws of New
Mexico, a Unitholder, even if not a resident of such state, could be subject to
devolution, probate and administration laws, and inheritance or estate and
similar taxes, under the laws of such state.

                             REGULATION AND PRICES

REGULATION OF NATURAL GAS

     The production, transportation and sale of natural gas from the Underlying
Properties are subject to Federal and state governmental regulation, including
regulation of tariffs charged by pipelines, taxes, the prevention of waste, the
conservation of gas, pollution controls and various other matters. The United
States has governmental power to impose pollution control measures.

     Federal Regulation of Gas. The Underlying Properties are subject to the
jurisdiction of the Federal Energy Regulatory Commission ("FERC") with respect
to various aspects of gas operations including marketing and production of gas.
As a result of the Natural Gas Policy Act of 1978 ("NGPA") and the Natural Gas
Wellhead Decontrol Act of 1989 ("NGWDA"), as of January 1, 1993, the wellhead
price for natural gas is no longer subject to federal regulation. All sales of
natural gas produced from the Underlying Properties are considered under NGPA
and NGWDA to be sold at the wellhead (as opposed to downstream sales or resales)
for purposes of pricing and therefore are not subject to federal regulation.

                                       18
<PAGE>   22

     The transportation of natural gas in interstate commerce is subject to
federal regulation by FERC under the Natural Gas Act ("NGA") and the NGPA. FERC
has initiated a number of regulatory policy initiatives that may affect the
transportation of natural gas from the wellhead to the market and thus may
affect the marketing of natural gas. Such initiatives include regulations which
are intended to further open access to interstate pipelines by requiring such
pipelines to unbundle their transportation services from sales services and
allow customers to choose and pay for only the services they require, regardless
of whether the customer purchases natural gas from such pipelines or from other
suppliers. Although these regulations should generally facilitate the
transportation of natural gas produced from the Underlying Properties to natural
gas markets, the impact of these regulations on marketing production from the
Underlying Properties cannot be predicted at this time, and such impacts could
be significant.

     Legislative Proposals. In the past, Congress has been very active in the
area of gas regulation. Legislation enacted in recent years repeals incremental
pricing requirements and gas use restraints previously applicable. At the
present time, it is impossible to predict what proposals, if any, might actually
be enacted by Congress or the various state legislatures and what effect, if
any, such proposals might have on the Underlying Properties and the Trust.

     State Regulation. Many state jurisdictions have at times imposed
limitations on the production of gas by restricting the rate of flow for gas
wells below their actual capacity to produce and by imposing acreage limitations
for the drilling of a well. States may also impose additional regulation of
these matters. Most states regulate the production of gas, including
requirements for obtaining drilling permits, the method of developing new
fields, provisions for the unitization or pooling of gas properties, the
spacing, operation, plugging and abandonment of wells and the prevention of
waste of gas resources. The rate of production may be regulated and the maximum
daily production allowable from gas wells may be established on a market demand
or conservation basis or both.

     Several states have in recent years enacted or proposed regulations
intended to revise significantly current systems of prorationing gas production.
If modified in New Mexico, such modified rules may decrease the total amount of
gas produced in New Mexico, and could result in an increase in market prices for
gas. The foregoing developments have fostered debate regarding the purpose and
effect of the new prorationing rules, with opponents of such rules arguing that
the primary purpose thereof is to increase gas prices by withholding supplies
from the market. The Trustee cannot predict what effect, if any, proration rules
will have on the availability of or prices for the Underlying Properties' gas
supplies.

ENVIRONMENTAL REGULATION

     General. Activities on the Underlying Properties are subject to existing
Federal, state and local laws (including case law), rules and regulations
governing health, safety, environmental quality and pollution control. It is
anticipated that, absent the occurrence of an extraordinary event, compliance
with existing Federal, state and local laws, rules and regulations regulating
health, safety, the release of materials into the environment or otherwise
relating to the protection of the environment will not have a material adverse
effect upon the Trust or Unitholders. The Trustee cannot predict what effect
additional regulation or legislation, enforcement policies thereunder, and
claims for damages to property, employees, other persons and the environment
resulting from operations on the Underlying Properties could have on the Trust
or Unitholders. However, any costs or expenses incurred by BROG in connection
with environmental liabilities arising out of or relating to activities
occurring on, in or in connection with, or conditions existing on or under, the
Underlying Properties before June 17, 1993 will be borne by BROG and not the
Trust (and BROG has indemnified the Trust with respect thereto) and such costs
and expenses will not be deducted in calculating NPI Net Proceeds or Infill Net
Proceeds. Any environmental costs or expenses that are attributable to BROG's
interest in the Underlying Properties that do not fall within the preceding
sentence (including indemnification obligations payable to or on behalf of the
Trustee or the Delaware Trustee relating to matters occurring on or after June
17, 1993) will be paid by BROG but will be deducted in calculating NPI Net
Proceeds or Infill Net Proceeds and will, therefore, reduce amounts payable to
the Trust.

                                       19
<PAGE>   23

     Solid and Hazardous Waste. The Underlying Properties are carved out of
leasehold interests in certain properties that have produced gas from other
formations for many years. Burlington Resources and BROG have advised the
Trustee that to their knowledge the operator of the Underlying Properties has
utilized operating and disposal practices that were standard in the industry at
the time, although hydrocarbons or other solid or hazardous wastes may have been
disposed or released on or under the Underlying Properties by the current or
previous operators. Federal, state and local laws applicable to gas-related
wastes and properties have become increasingly more stringent. Under these laws,
the operator of the Underlying Properties or the working interest owners could
be required to remove or remediate previously disposed wastes or property
contamination (including groundwater contamination) or to perform remedial
plugging operations to prevent future contamination.

     The operations of the Underlying Properties may generate wastes that are
subject to the Federal Resource Conservation and Recovery Act ("RCRA") and
comparable state statutes. The Environmental Protection Agency (the "EPA") has
limited the disposal options for certain hazardous wastes and may adopt more
stringent disposal standards for nonhazardous wastes.

     The operations of the Underlying Properties include the disposal of
produced saltwater by reinjection into the subsurface. Such operations are
subject to Federal and state regulations concerning Class II underground
injection control disposal systems, which are used to dispose of fluids in
connection with oil or natural gas production. To protect against contamination
of drinking water, existing regulations contain stringent requirements relating
to the construction, operation, monitoring, plugging and abandonment of
underground injection wells. If the operator of the reinjection wells fails to
maintain the mechanical integrity of the reinjection wells, the operator of the
Underlying Properties or the working interest owners could be required to cease
injection and perform additional construction, operation, monitoring or
corrective action.

     Superfund. The Comprehensive Environmental Response, Compensation and
Liability Act ("CERCLA"), also known as the "superfund" law, imposes liability,
regardless of fault or the legality of the original conduct, on certain classes
of persons that contributed to the release of a "hazardous substance" into the
environment. These persons include the current or previous owner and operator of
a site and companies that disposed, or arranged for the disposal, of the
hazardous substance found at a site. CERCLA also authorizes the EPA and, in some
cases, private parties to take actions in response to threats to the public
health or the environment and to seek recovery from such responsible classes of
persons of the costs of such action. In the course of its operations, the
operator of the Underlying Properties has generated and will generate wastes
that may fall within CERCLA's definition of "hazardous substances." The operator
of the Underlying Properties or the working interest owners may be responsible
under CERCLA for all or part of the costs to clean up sites at which such
substances have been disposed. Any such CERCLA liabilities borne by BROG may be
passed on, proportionately, to the Trust (through deduction of such amounts in
calculating NPI Net Proceeds) only to the extent that any such liability relates
to activities occurring on or under, or in connection with, or conditions
existing on or under, the Underlying Properties on or after June 17, 1993. All
other CERCLA liabilities in connection with BROG's interest in the Underlying
Properties were retained by BROG.

     Air Emissions. The operations of the Underlying Properties are subject to
Federal, state and local regulations concerning the control of emissions from
sources of air contaminants. Administrative enforcement actions for failure to
comply strictly with air regulations or permits are generally resolved by
payment of a monetary penalty and correction of any identified deficiencies.
Regulatory agencies could require the operators to forego or modify construction
or operation of certain air emission sources.

     OSHA. The operations of the Underlying Properties are subject to the
requirements of the Federal Occupational Safety and Health Act ("OSHA") and
comparable state statutes. The OSHA hazard communication standard, the EPA
community right-to-know regulations under Title III of the Federal Superfund
Amendment and Reauthorization Act and similar state statutes require that
information be organized and maintained about hazardous materials used or
produced in the operations. Certain of this information must be provided to
employees, state and local government authorities and citizens.

COMPETITION, MARKETS AND PRICES

     The revenues of the Trust and the amount of cash distributions to
Unitholders depend upon, among other things, the effect of competition and other
factors in the market for natural gas. The gas industry is highly competitive in
all of its phases. BROG encounters competition from major oil and gas companies,
independent oil and gas concerns, and individual producers and operators. Many
of these competitors have greater financial and other resources than BROG.
Competition may also be presented by alternative fuel sources, including heating
oil and other fossil fuels.

     Demand for natural gas production has historically been seasonal in nature
and prices for gas fluctuate accordingly. Due to unseasonably warm weather over
the last several years and the ability of markets to access storage, lower
prices have been received by producers than in prior years. Consequently, on an
energy equivalent basis, gas has sold at a discount to oil for the past several
years. However, during 1997 inventories were down and various market conditions
created more demand for natural gas throughout the year. Such price fluctuations
and the continuation of a variable market for natural gas will directly impact
Trust distributions, estimates of Trust reserves and estimated future net
revenue from Trust reserves.

     Prices for natural gas are subject to wide fluctuations in response to
relatively minor changes in supply, market uncertainty and a variety of
additional factors that are beyond the control of the Trust and Burlington
Resources. These factors include political conditions in the Middle East, the
price and quantity of imported oil and gas, the level of consumer product
demand, the severity of weather conditions, government regulations, the price
and availability of alternative fuels and overall economic conditions.
Additionally, lower natural gas prices may reduce the amount of gas that is
economic to produce from the Underlying Properties. In view of the many
uncertainties affecting the supply and demand for natural gas, the Trust and
Burlington Resources are unable to make reliable predictions of future gas
prices and demand or the overall effect they will have on the Trust.

ITEM 2. PROPERTIES.

                             THE ROYALTY INTERESTS

     The Royalty Interests conveyed to the Trust entitle the Unitholders to
receive 95 percent of the NPI Net Proceeds attributable to BROG's interest in
the Underlying Properties and 20 percent of BROG's interest in the Infill Net
Proceeds attributable to any Infill Wells that may be drilled after May 1, 1993.
The Royalty Interests were conveyed to the Trust by means of a single instrument
of conveyance. The Conveyance was recorded in the appropriate real property
records in San Juan and Rio Arriba counties in New Mexico so as to give notice
of the Royalty Interests to creditors and any transferees, who would take an
interest in the Underlying Properties subject to the Royalty Interests. The
Conveyance was intended to convey the Royalty Interests as real property
interests under New Mexico law.

     Burlington Resources, through BROG, owns an interest in the Underlying
Properties subject to and burdened by the Royalty Interests conveyed to the
Trust pursuant to the Conveyance. BROG receives all payments relating to its
interest in the Underlying Properties and is required, pursuant to the
Conveyance, to pay to the Trust the portion thereof attributable to the Royalty
Interests. Under the Conveyance, the amounts payable by BROG with respect to the
Royalty Interests are computed with respect to each calendar quarter ending
prior to termination of the Trust, and such amounts are to be paid to the Trust
not later than the 50th day following the end of each calendar quarter. The
amounts paid to the Trust will not include interest on any amounts payable with
respect to the Royalty Interests which are held by BROG prior to payment to the
Trust. BROG is entitled to retain all amounts attributable to its interest in
the Underlying Properties which are not required to be paid to the Trust with
respect to the Royalty Interests.

     The following description contains a summary of the material terms of the
Conveyance and is subject to and qualified by the more detailed provisions of
the Conveyance, a copy of which is filed as an exhibit to this 10-K.

THE UNDERLYING PROPERTIES

     The Royalty Interests were conveyed by BROG to the Trust out of its net
revenue interest in the Underlying Properties. All of the production from the
Underlying Properties is from the Northeast Blanco Unit in the Fruitland coal
formation in the San Juan Basin in San Juan and Rio Arriba counties in New
Mexico. For the purpose of determining the extent of the Underlying Properties,
as used in this Form 10-K the term "Northeast Blanco Unit" comprises the
Northeast Blanco Unit, a 32,595 acre unit originally formed on July 16, 1951, as
well as rights in one communitized gross well with acreage in both the Northeast
Blanco Unit and the adjoining San Juan 30-6 Unit. The Underlying Properties do
not include BROG's interest in formations other than the Fruitland coal
formation underlying the Northeast Blanco Unit. The Northeast Blanco Unit is
located in the north-central portion of the San Juan Basin. The San Juan Basin
has been an active area for coal seam gas development, and wells have been
drilled on each of the 320 acre drill blocks within the Northeast Blanco Unit.

     The Royalty Interests transferred in the Conveyance to the Trust do not
burden the mineral interests or overriding royalty interests owned by El Paso
Production Company (a wholly owned subsidiary of Burlington Resources), the
royalty and overriding royalty interests owned by Southland Royalty Company (a
wholly owned subsidiary of Burlington Resources and the sponsor of the San Juan
Basin Royalty Trust) or the interests owned by the San Juan Basin Royalty Trust,
respectively, in the Northeast Blanco Unit. El Paso Production Company owns a
 .138 percent working interest and a .178 percent net revenue interest in the
Northeast Blanco Unit attributable to its mineral interests and overriding
royalty interests. Southland Royalty Company owns a .221 percent net revenue
interest in the Northeast Blanco Unit attributable to its royalty interests and
overriding royalty interests. Both entities were merged into Burlington
Resources Oil & Gas Company in 1996.

     Unitized Areas. Pursuant to the Federal Mineral Leasing Act of 1920, as
amended, and applicable state regulations, owners of oil and gas leases in New
Mexico created large unitized areas consisting of numerous contiguous sections
for the orderly development and conservation of oil and gas reserves. All of the
Fruitland coal seam gas wells on the Underlying Properties are located within
such a unitized area. Operation and development of the Northeast Blanco Unit is
governed by a unit agreement and a unit operating agreement (collectively, the
"Unit Agreement"). Under the Unit Agreement and applicable government
regulations, the unit operator requests regulatory approval from the New Mexico
Commission of Public Lands, the New Mexico Oil Conservation Division and the
Bureau of Land Management of the U.S. Department of Interior (the "Bureau of
Land Management") to establish or expand participating areas which produce oil
and gas in paying quantities from designated formations. The working interests
of participants in a participating area are based on the surface acreage
included in the participating area. Under the terms of the Unit Agreement, the
operator, selected by a vote of the respective working interest owners, performs
all operating functions.

     The Underlying Properties currently include 101 gross coal seam wells. One
additional previously existing well in the Northeast Blanco Unit has ceased
production, and no reserves have been attributed to such well in the December
31, 1997 Reserve Report. If subsequently deemed appropriate by the Northeast
Blanco Unit working interest owners, such well could be redrilled and, if
returned to production, BROG's interest in that well would be burdened by the
NPI. BROG's working interest share of the capital costs of any such redrilling
would be deducted in calculating NPI Net Proceeds and would, therefore, reduce
amounts payable to the Trust. In addition, any production from that redrilled
well would not entitle Unitholders to Section 29 tax credits. As of December 31,
1997, BROG had a working interest of approximately 16.5 percent in the
Underlying Properties and a net revenue interest of approximately 19.8 ercent in
the Underlying Properties. The operator of the Underlying Properties is
Blackwood & Nichols Co. ("B&N"), an affiliate of Devon Energy Corporation
("Devon") (although the single communitized well included within the Underlying
Properties is operated by BROG).

<PAGE>   26

     Adjacent Properties. In addition to the San Juan 30-6 Unit, BROG and its
affiliates own significant interests in five other Federal units and eleven
non-unitized wells that are adjacent to the Northeast Blanco Unit. Two of the
Federal units (the San Juan 30-6 Unit and the Allison Unit) are operated by BROG
or its affiliates. It is possible that production from these properties could
drain coal seam gas from the Underlying Properties and therefore reduce
production from the wells burdened by the Royalty Interests. However, if
drainage were to occur it should be insignificant because of the well spacing
rules and well "set back" rules that have been established by the New Mexico Oil
Conservation Division. These rules are designed to protect the correlative
rights of each owner by limiting the number of wells that can be drilled and
establishing a reasonable distance from adjoining lease or unit boundaries that
each well can be drilled. Currently, the rules in effect for the Fruitland coal
formation provide for one well to be drilled on a 320 acre drillblock and
require each well to be drilled no closer than 790 feet from the adjacent lease
boundary.

     Working Interest Owners. The following is a list of working interest owners
in the Underlying Properties owning at least a one percent working interest as
of December 31, 1997.

THE NPI

     The NPI generally entitles the Trust to receive 95 percent of the NPI Net
Proceeds attributable to BROG's interest in the Underlying Properties, subject
to possible decrease as described under "-- Possible NPI Percentage Reduction."

     BROG will pay its working interest share of capital costs incurred on the
Underlying Properties. Such capital costs will be equal to BROG's working
interest share of the amounts expended by the operator of the Northeast Blanco
Unit and BROG will be invoiced for its share of those costs by the operator.
However, the operator and working interest owners of the wells could elect at
any time to implement measures to increase the producible reserves. These
measures, if implemented, could involve additional compression or enhanced or
secondary recovery operations requiring substantial capital expenditures which
would be proportionately borne by the NPI. During 1997 significant capital
expenditures were made in conjunction with the installation of a looped gas
gathering system.

     All cumulative lease operating expenses paid after May 1, 1993, and capital
expenses paid on or after January 1, 1994, attributable to BROG's working
interest in the Underlying Properties (other than any environmental liabilities
related to activities occurring on or under, or in connection with, or
conditions existing on or under, the Underlying Properties before June 17, 1993,
which liabilities will be borne by BROG and for which BROG has indemnified the
Trust) will be deducted in calculating NPI Net Proceeds and, therefore, will
reduce amounts payable to the Trust.

                                       23
<PAGE>   27

     If, during any calendar quarter, costs and expenses paid by BROG and
deducted in calculating the NPI Net Proceeds exceed gross proceeds (such excess
referred to as a "Deficit"), neither the Trust nor Unitholders will be liable to
pay such Deficit directly, but the Trust will receive no payments for
distribution to Unitholders (although BROG will pay to the Trust amounts
sufficient to pay the administrative expenses of the Trust) until future gross
proceeds exceed future costs and expenses plus the cumulative Deficit and
interest on such cumulative Deficit at Citibank's Base Rate; provided, however,
that in any calendar quarter in which the cumulative Deficit at the end of such
quarter is less than $3,000,000, BROG will pay to the Trust for distribution to
Unitholders no less than 20 percent of such quarter's NPI Net Proceeds
(calculated before deducting capital costs for such calendar quarter); and
provided further, that if at the end of any calendar quarter, the cumulative
Deficit is $3,000,000 or more, BROG will not be obligated to make any payment to
the Trust for distribution to Unitholders (although BROG will pay to the Trust
amounts sufficient to pay the administrative expenses of the Trust) until such
cumulative Deficit is reduced to less than $3,000,000. As of December 31, 1997
no such deficit existed.

RESERVE REPORT

     The following table summarizes net proved reserves estimated as of December
31, 1997, and certain related information for the Royalty Interests and BROG's
interest in the Underlying Properties from the December 31, 1997 Reserve Report
prepared by Netherland, Sewell & Associates, Inc., independent petroleum
engineers. All of such reserves constitute proved developed reserves. Summaries
of the December 31, 1997 Reserve Report, the Prior Reserve Reports and the Prior
Tax Credit Reports are filed as exhibits to this Form 10-K and incorporated
herein by reference. See Note 9 of the Notes to Financial Statements included in
Item 8 hereof for additional information regarding the net proved reserves of
the Trust.

     A net profits interest does not entitle the Trust to a specific quantity of
gas but to a portion of gas sufficient to yield a specified portion of the net
proceeds derived therefrom. Proved reserves attributable to a net profits
interest are calculated by deducting an amount of gas sufficient, if sold at the
prices used in preparing the reserve estimates for such net profits interest, to
pay the future estimated costs and expenses deducted in the calculation of the
net proceeds of such interest. Accordingly, the reserves presented for the
Royalty Interests reflect quantities of gas that are free of future costs and
expenses if the price and cost assumptions used in the December 31, 1997 Reserve
Report occur. The December 31, 1997 Reserve Report was prepared in accordance
with criteria established by the Securities and Exchange Commission. At December
31, 1997, the price the Trust was entitled to receive under the Gas Purchase
Contract was $2.07 per MMBtu subject to accrued and unrecouped Price Credits in
the Price Credit Account (see "-- The Royalty Interests -- Gas Purchase
Contract"). For purposes of the preparation of the December 31, 1997 Reserve
Report, however, pricing was held constant at the Minimum Purchase Price of
$1.60 per MMBtu until the accrued Price Credits were recouped by BRTI, after
which $2.07 per MMBtu was utilized for the remaining life of the Royalty
Interests.

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

(a)  Although the prices utilized in preparing the estimates in this table are
     in accordance with criteria established by the Securities and Exchange
     Commission, those prices were influenced by seasonal demand for natural gas
     and other factors and may not be the most representative prices for
     estimating future net revenues or related reserve data. In addition,
     changes in gas prices have an effect on net reserve data for the NPI at any
     given level of costs assumed, because such changes in the cost of gas per
     MMBtu result in changes in the number of MMBtu required to pay a given
     level of costs. Since December 31, 1997, the Blanco Hub Spot Price has
     remained above the minimum price.

                                       24
<PAGE>   28

(b)  The gas reserves were estimated by Netherland, Sewell & Associates, Inc. by
     applying volumetric and decline curve analyses.

(c)  Estimated future net revenues are defined as the total revenues
     attributable to BROG's interest in the Underlying Properties and to the
     Royalty Interests less the relevant share (BROG's interest share, in the
     case of BROG's interest in the Underlying Properties, and 95 percent
     thereof, in the case of the Royalty Interests) of royalties, production,
     property and related taxes (including severance taxes), lease operating
     expenses and future capital expenditures. Overhead costs (beyond the
     standard overhead charges for the nonoperated properties) have not been
     included, nor have the effects of depreciation, depletion and Federal
     income tax. Estimated future net revenues and discounted estimated future
     net revenues are not intended and should not be interpreted as representing
     the fair market value for the estimated reserves.

     Based upon the production estimates used in the December 31, 1997 Section
29 Tax Credit Report for the January 1, 1998 through December 31, 2002 period,
and assuming constant future Section 29 tax credits at the estimated 1997 rate
of $1.0758 per MMBtu, the estimated total future tax credits available from the
production and sale of the net proved reserves from the Royalty Interests would
be approximately $31.6 million, having a discounted present value (assuming a 10
percent discount rate) of approximately $25.9 million.

     There are many uncertainties inherent in estimating quantities and values
of proved reserves and in projecting future rates of production and the timing
of development expenditures. The reserve data set forth herein are estimates
only, and actual quantities and values of natural gas are likely to differ from
the estimated amounts set forth herein. In addition, the reserve estimates for
the Royalty Interests will be affected by future changes in sales prices for
natural gas produced and costs that are deducted in calculating NPI Net Proceeds
and Infill Net Proceeds. Further, the discounted present values shown herein
were prepared using guidelines established by the Securities and Exchange
Commission for disclosure of reserves and should not be considered
representative of the market value of such reserves or the Units. A market value
determination would include many additional factors.

POSSIBLE NPI PERCENTAGE REDUCTION

     If there has been cumulative production after April 30, 1993 (other than
production attributable to Infill Wells) of at least 161.8 Bcf of natural gas
attributable to BROG's interest in the Underlying Properties burdened by the
NPI, the percentage of NPI Net Proceeds payable in respect of the NPI will be
reduced with respect to any additional production from BROG's interest in the
Underlying Properties if the IRR of the "After-tax Cash Flow per Unit" (as
defined below) exceeds 11 percent (or if, as set forth below, a greater amount
of gas has been produced and certain other financial tests are met). For
purposes hereof, "After-tax Cash Flow per Unit" is equal to the sum of the
following amounts that a hypothetical purchaser of a Unit in the Public Offering
would have received or been allocated if such Unit were held through the date of
such determination: (a) total cash distributions per Unit plus (b) total tax
credits available per Unit under Section 29 of the IRC less (c) the total net
taxes payable per Unit (assuming a 31 percent tax rate, the

                                       25
<PAGE>   29

highest effective Federal income tax rate applicable to individuals at the time
of the Public Offering). IRR is the annual discount rate (compounded quarterly)
that equates the present value of the After-tax Cash Flow per Unit to the $20.50
initial price to the public of the Units in the Public Offering. Set forth below
is a table that reflects the cumulative production from BROG's interest in the
Underlying Properties after April 30, 1993 (other than production attributable
to Infill Wells) and the corresponding percentage of NPI Net Proceeds
represented by the NPI and the retained interest of BROG in the NPI Net
Proceeds:

</TABLE>

     In addition to the foregoing, the percentage of NPI Net Proceeds payable to
the Trust will be reduced to 25 percent and BROG's retained percentage of NPI
Net Proceeds will be increased to 75 percent (whether or not the IRR of the
After-tax Cash Flow per Unit exceeds 11 percent) if (i)(a) after April 30, 1993
there has been total production (other than production attributable to Infill
Wells) attributable to BROG's interest in the Underlying Properties of more than
191.2 Bcf of natural gas, (b) a hypothetical purchaser of a Unit in the Public
Offering would have received a cash return (equal to total cash distributions
per Unit) of not less than the $20.50 initial offering price in the Public
Offering and (c) total capital expenditures (excluding capital expenditures in
connection with any Infill Wells) incurred between May 1, 1993 and December 31,
2002 and attributable to BROG's interest in the Underlying Properties do not
exceed $20 million (adjusted for inflation between May 1, 1993 and December 31,
2002), or (ii)(a) after April 30, 1993 there has been total production (other
than production attributable to Infill Wells) attributable to BROG's interest in
the Underlying Properties of more than 220.7 Bcf of natural gas and (b) a
hypothetical purchaser of a Unit in the Public Offering would have received a
cash return satisfying the criteria set forth in (i)(b) above.

     The percentage of NPI Net Proceeds payable in respect of the NPI will be
reduced at any time and from time to time in the amounts set forth above if the
criteria specified in the preceding paragraphs are met. If a reduction in the
percentage of NPI Net Proceeds constituting the NPI occurs, that reduced
percentage shall continue in effect thereafter unless and until a further
reduction occurs. As of December 31, 1997 none of the criteria described above
had been met.

GAS PURCHASE CONTRACT

     Under the terms of the Gas Purchase Contract, BRTI is obligated to purchase
the natural gas attributable to BROG's interest in the Underlying Properties at
the Central Gathering Point. The Gas Purchase Contract commenced as of May 1,
1993, and expires on the termination of the Trust. The monthly price to be paid
by BRTI for natural gas purchased pursuant to the Gas Purchase Contract is,
subject to applicable adjustment, (i) the $1.60 per MMBtu Minimum Purchase Price
less (ii) all costs to be incurred in connection with gathering and/or
transportation charges, taxes, treating and processing costs and other costs
payable in connection with such services from the Central Gathering Point to
main line delivery (collectively, "Deductible Costs"). Additionally, if BRTI's
arrangements for gathering, treating, processing and transporting gas from the
Central Gathering Point are altered by any governmental order, decree,
legislation or regulation relating generally to gathering and transportation
arrangements in the natural gas industry and such alterations materially
increase BRTI's costs of performing its obligations under the Gas Purchase
Contract, such increased costs shall be included in Deductible Costs to the
extent that such increased costs are not recouped by BRTI from its gas
purchaser. The monthly price is subject to adjustments under certain
circumstances as described below:

          (a) If the Index Price in any month is greater than the $2.04 per
     MMBtu Sharing Price, then BRTI will pay BROG an amount for each MMBtu of
     gas purchased equal to the Sharing Price for such month, less the
     Deductible Costs for such month, plus 50 percent of the excess of the Index
     Price for such month

                                       26
<PAGE>   30

     over the Sharing Price (the "Price Differential") for such month, provided
     BRTI has no accrued and unrecouped Price Credits (defined below) in the
     Price Credit Account (defined below). If BRTI has accrued and unrecouped
     Price Credits in the Price Credit Account, then BRTI will be entitled to
     reduce the amount in excess of the Minimum Purchase Price (before deducting
     the Deductible Costs) that otherwise would be payable for such month by the
     quotient of the balance of accrued and unrecouped Price Credits in the
     Price Credit Account as of the beginning of such month divided by the
     quantity of BROG's gas purchased for such month under the Gas Purchase
     Contract.

          (b) If the Index Price in any month is greater than or equal to the
     Minimum Purchase Price but less than or equal to the Sharing Price for such
     month, then BRTI will pay BROG an amount for each MMBtu of gas purchased
     during such month equal to the Index Price for such month less the
     Deductible Costs for such month provided BRTI has no accrued and unrecouped
     Price Credits in the Price Credit Account. If BRTI has accrued and
     unrecouped Price Credits in the Price Credit Account, then BRTI will be
     entitled to reduce the amount in excess of the Minimum Purchase Price
     (before deducting the Deductible Costs) that otherwise would be payable for
     such month by the quotient of the balance of accrued and unrecouped Price
     Credits in the Price Credit Account as of the beginning of such month
     divided by the quantity of BROG's gas purchased for such month under the
     Gas Purchase Contract.

          (c) If the Index Price in any month commencing after December 31, 1993
     is less than the Minimum Purchase Price, then BRTI will pay for each MMBtu
     of gas purchased the Minimum Purchase Price less the Deductible Costs for
     such month, and BRTI will receive a credit (a "Price Credit") from BROG for
     each MMBtu of natural gas so purchased by BRTI equal to the difference
     between the Minimum Purchase Price and the Index Price. BRTI is required to
     establish and maintain an account (the "Price Credit Account") containing
     the accrued and unrecouped amount of such Price Credits.

     The Index Price was below the Minimum Purchase Price from 1995 through
1996, with the exception of the months of August, November and December of 1996.
The Index Price was above the Minimum Purchase Price during 1997 except for
March and April of 1997, resulting in a net reduction of the Price Credit
Account of $3.3 million. BRTI estimates that, as of December 31, 1997, BRTI had
aggregate Price Credits in the Price Credit Account of approximately $5.6
million of which the Trust's 95 percent interest was approximately $5.3 million.

     This entitlement to recoup the Price Credits means that if and when the
Index Price is above the Minimum Purchase Price, 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.

     Each of the Minimum Purchase Price and the Sharing Price will increase by
2.5 percent per annum as of May 1 of each year commencing in 2003.

     The Central Gathering Point price in the Gas Purchase Contract is
determined by utilizing a published price (which is before deduction of
Deductible Costs), and then deducting Deductible Costs. As used herein, "Index
Price" means for each month 97 percent of the Blanco Hub Spot Price (such 3
percent deduction constituting a discount to compensate BRTI for marketing the
gas). The Blanco Hub Spot Price is a posted index price in dollars per MMBtu on
a dry basis published in the first issue of such month in Inside FERC's Gas
Market Report for "El Paso Natural Gas Company, San Juan." Pursuant to the Gas
Purchase Contract, BRTI will have a one-time option to elect to substitute for
the foregoing as the Blanco Hub Spot Price either (i) the average of the two
posted index prices reported each month in Inside FERC's Gas Market Report for
"El Paso Natural Gas Company, San Juan" or (ii) the Blanco Hub posted index
price reported by Inside FERC's Gas Market Report, if either such price is then
published in such publication. All prices used as index prices are delivered
prices at the specified point of delivery and are, therefore, before deducting
Deductible Costs.

     In any month in which BRTI recoups Price Credits under the Gas Purchase
Contract, BROG may be required to calculate royalty payments attributable to
production from the Underlying Properties based on the higher price BRTI
receives when it resells the gas production instead of the lower price payable
by BRTI to
                                       27
<PAGE>   31

BROG under the Gas Purchase Contract (which price takes into account the Price
Credits recouped by BRTI in such month). Royalties that are payable by BROG in
respect of such higher gas price will not reduce the NPI Net Proceeds payable to
the Trust. However, the portion of the recouped Price Credits that is
attributable to the royalty percentage of the gas sold in such month shall be
returned to the Price Credit Account by BRTI and recouped by BRTI in future
months.

     The Underlying Properties are subject to a gas balancing agreement which,
under certain circumstances, allows any working interest owner (including BROG)
to take more or less than his working interest share of gas produced. NPI Net
Proceeds and Infill Net Proceeds are calculated on an "entitlements basis,"
whereby the aggregate proceeds from the sale of gas are determined by BROG as if
BROG had produced and sold its share of production from the Underlying
Properties, even if the actual volumes delivered to and sold by BROG are
different from its entitled interest volumes. The effect of such an entitlements
basis calculation is that NPI Net Proceeds or Infill Net Proceeds and,
therefore, the amount thereof paid to the Trust, may include amounts in respect
of production not taken by BROG because of an imbalance (an imbalance is where
an interest owner is delivered more or less than the actual share of production
to which it is entitled). Likewise, in the event BROG actually takes and sells
more than its share of production but pays the NPI Net Proceeds or the Infill
Net Proceeds on an entitlements basis, BROG will receive revenues in excess of
those distributed to the Trust. In the event the price of gas is lower when the
other interest owners make-up the overproduction taken and sold by BROG than the
price received by BROG, BROG will retain the excess of such higher price over
the lower price.

     BROG bases such entitlements calculations upon production estimates
furnished to BROG by the operator of the Underlying Properties, which estimates
may be subject to subsequent adjustment by the operator after the collection and
evaluation of field data. Because the operator may not determine that such an
adjustment is required until several months after the original estimates are
furnished to BROG, it is possible that an adjustment with respect to a
particular quarter will not be made until cash amounts have been distributed,
and depletion and Section 29 tax credits have been allocated to Unitholders by
the Trust. BROG will take such an adjustment into account for the quarter in
which BROG is advised of such adjustment. The cash distributions made, and
depletion deductions and Section 29 tax credits allocated, in respect of a
future quarterly period on a Unit could be based in part upon such an
adjustment, notwithstanding that the owner of such Unit did not own the Unit
during the quarter in respect of which such adjustment is made.

     BRTI's obligation to purchase natural gas pursuant to the Gas Purchase
Contract (as well as BROG's obligation to sell such gas) may be suspended to the
extent affected by the occurrence of any event that renders the affected party
unable to perform its obligations under the Gas Purchase Contract if the event
could not have been prevented with reasonable foresight, at reasonable cost and
by the exercise of reasonable diligence including: (i) acts of God, lightning,
fires, explosions and other casualties, (ii) strikes and other industrial
disturbances, (iii) acts of the public enemy, wars, epidemics, restraints of
government, civil disturbances, and acts, orders and regulations of governmental
agencies, (iv) inability to acquire or delay in acquiring materials, equipment,
rights-of-way and approvals of regulatory bodies, (v) physical constraint or
restriction of, or accident or blockage of or to, equipment or lines of pipe and
(vi) interruption of BRTI's gathering, treating, processing or transportation
arrangements relating to production from the Underlying Properties, including
such arrangements under the Gas Gathering Contract. Following any such event,
the affected party's obligations under the Gas Purchase Contract will be
suspended during the period of its inability to perform, and such party will use
reasonable efforts to remedy the event and resume full performance as quickly as
reasonably practical.

     Although BRTI will likely utilize the natural gas purchased from BROG
pursuant to the Gas Purchase Contract to satisfy its obligations under a number
of resale agreements with third parties, none of the gas purchased by BRTI
pursuant to any gas purchase agreement (including the Gas Purchase Contract) has
been dedicated to any particular resale agreement, and the arrangements made by
BRTI with respect to reselling any gas purchased by it vary from time to time.
The prices to be paid by third party purchasers, therefore, may also be expected
to vary from time to time, and may be either less than or greater than the price
paid by BRTI pursuant to the Gas Purchase Contract. At times when the Minimum
Purchase Price exceeds the Index Price, BRTI will be required to purchase gas at
a price based on the Minimum Purchase Price. At times when the
                                       28
<PAGE>   32

Index Price exceeds the Sharing Price, BRTI will receive a benefit from being
able to resell gas at prices generally reflecting the full amount of the excess
of the Index Price over the Sharing Price, while paying BROG and, therefore, the
Trust an amount generally reflecting only 50 percent of such excess.

     The Gas Purchase Contract may not be terminated without the consent of BRTI
and BROG. Further, it may not be amended in a manner that would materially
adversely affect the revenues to the Trust without the approval of the holders
of a majority of the Units then outstanding. The Gas Purchase Contract is filed
as an exhibit to this Form 10-K. The foregoing summary of the material
provisions of the Gas Purchase Contract is qualified in its entirety by
reference to the terms of such agreement as set forth in such exhibit.

GAS GATHERING CONTRACT

     The prices to be paid to BROG pursuant to the Gas Purchase Contract are
prices payable for the value of gas purchased for production at the Central
Gathering Point. Title to the gas purchased pursuant to the Gas Purchase
Contract, therefore, passes to BRTI at the Central Gathering Point. BRTI is
responsible for gathering, treating, processing and marketing from the Central
Gathering Point all gas purchased pursuant to the Gas Purchase Contract. The
price paid by BRTI pursuant to the Gas Purchase Contract is after deducting
Deductible Costs from the Central Gathering Point. Pursuant to the Gas Gathering
Contract, BRGI gathers, treats and processes all of the production attributable
to BROG's interest in the Underlying Properties (excluding production
attributable to five wells) from the Central Gathering Point. BRGI, under the
Gas Gathering Contract, treats the gas gathered for BRTI to remove carbon
dioxide and water and to otherwise bring the gas into compliance with the
specifications of the Gas Gathering Contract. At December 31, 1997, BRGI's rates
for performing its services under the Gas Gathering Contract varied from
approximately $.34 to approximately $.45 per Mcf, depending upon the specific
point of delivery to BRGI. BRTI reduces the price that it pays for the gas by
the value of gas used by BRGI as fuel for compression and other facilities.
These reductions can not exceed 6.5 percent of the value of volumes of gas
gathered for BRTI. The rates payable to BRGI pursuant to the Gas Gathering
Contract are subject to annual adjustment on January 1 of each year on the basis
of increases or decreases in a published index measuring consumer prices.
Additionally, these rates may be increased by the amount of any additional costs
incurred by BRGI as a direct result of any governmental action relating
generally to gathering and/or treating agreements in the natural gas industry.
The term of the Gas Gathering Contract will continue until December 31, 2012;
thereafter, such contract will continue in effect on a month-to-month basis.

     All of the gas gathered pursuant to the Gas Gathering Contract must first
be gathered from the wellhead to the Central Gathering Point by a unit gathering
system owned by the working interest owners of the Northeast Blanco Unit. The
costs of such initial gathering (including maintenance of the gathering system)
are borne by such working interest owners (including BROG) and deducted as lease
operating expenses in calculating the NPI Net Proceeds or Infill Net Proceeds,
as the case may be. BROG does not anticipate any changes in the manner in which
gas will be gathered at the wellhead and transported to the Central Gathering
Point, or in the arrangements relating to use and maintenance of the Northeast
Blanco Unit gathering system.

     The Gas Gathering Contract may not be amended in a manner that would
materially adversely affect the revenues to the Trust without the approval of
the holders of a majority of the Units then outstanding. The Gas Gathering
Contract is filed as an exhibit to this Form 10-K. The foregoing summary of the
material provisions of the Gas Gathering Contract is qualified in its entirety
by reference to the terms of such agreement as set forth in such exhibit.

FEDERAL LANDS

     Approximately 80 percent of the Underlying Properties are burdened by
royalty interests held by the Federal government. Royalty payments due to the
U.S. government for gas produced from Federal lands included in the Underlying
Properties must be calculated in conformance with a working interest owner's
interpretation of regulations issued by the Minerals Management Service ("MMS"),
a subagency of the U.S. Department of the Interior that administers and receives
revenues from Federal royalties on behalf of the U.S. government. The MMS
regulations cover both valuation standards which establish the basis for placing
a

                                       29
<PAGE>   33

value on production and cost allowances which define those post-production costs
that are deductible by the lessee.

     Where gas is sold by a lessee to an affiliate such as BRTI, the MMS
regulations (as well as state regulations with respect to severance taxes) may
ignore the lessee-affiliate transaction and consider the arm's-length sale by
the affiliate as the point of valuation for royalty purposes. Accordingly, BROG
may be required to calculate royalty payments and severance taxes based on the
price BRTI receives when it markets the gas production (the "Resale Price"),
notwithstanding the price payable by BRTI to BROG pursuant to the Gas Purchase
Contract. Although the NPI Net Proceeds, 95 percent of which is payable to the
Trust, will reflect the deduction of all royalty and overriding royalty burdens
and state severance taxes, to the extent that the Resale Price exceeds the price
paid for production purchased under the Gas Purchase Contract, NPI Net Proceeds
will not be reduced by the royalties, but will be reduced by the severance
taxes, payable in respect of such excess. Royalties payable in respect of such
excess will be borne by BROG.

     The MMS regulations permit a lessee to deduct from its gross proceeds its
reasonable actual costs of transportation and processing to transport the gas
from the lease to the point of sale in calculating the market value of its
production. Although BROG will deduct (i) the Deductible Costs paid by BRTI
pursuant to the Gas Gathering Contract and (ii) the gathering charges payable by
BROG as a working interest owner of the Northeast Blanco Unit gathering system
in calculating the wellhead price of gas produced by BROG, the MMS could
disallow the deduction of some portion of such charges after review of such
charges on audit of BROG's royalty as discussed below. If some portion of such
charges is disallowed, the MMS will likely demand additional royalties plus
interest on the amount of the underpayment.

     The Trustee has been advised by BROG that the MMS has from time to time
considered the inclusion of the value of the Section 29 tax credits attributable
to coal seam gas production in the calculation of gross proceeds for purposes of
calculating the royalty that is payable to the MMS. On August 30, 1993, the U.S.
Office of the Inspector General (the "OIG") issued an audit report stating the
view that Section 29 tax credits should be included in the calculation of gross
proceeds and recommending that the MMS pursue collection of additional royalties
with respect to past and future production. On December 8, 1993, however, the
Office of the Solicitor of the U.S. Department of the Interior gave its opinion
to the MMS that the report of the OIG was incorrect and that Section 29 tax
credits are not part of gross proceeds for the purpose of federal royalty
calculations. BROG believes that any inclusion of the value of Section 29 tax
credits for purposes of calculating royalty payments required to be made on
Federal lands would be inappropriate since all mineral interest owners,
including royalty owners, are entitled to Section 29 tax credits for their
proportionate share of qualifying coal seam gas production. BROG has advised the
Trustee that it would vigorously oppose any attempt by the MMS to require the
inclusion of the value of Section 29 tax credits in the calculation of gross
proceeds. However, if regulations so to include such value were adopted and
upheld, royalty payments would be increased which would decrease NPI Net
Proceeds and, therefore, amounts payable to the Trust. The reduction in amounts
payable to the Trust would cause a corresponding reduction in associated Section
29 tax credits available to Unitholders.

     The MMS generally audits royalty payments within a six-year period.
Although BROG calculates royalty payments in accordance with its interpretation
of the then applicable MMS regulations, BROG does not know whether the royalty
payments made to the U.S. government are totally in conformity with MMS
standards until the payments are audited. If an MMS audit, or any other audit by
a Federal or state body, results in additional royalty charges, together with
interest, relating to production from and after the consummation of the Public
Offering in respect of BROG's interest in the Underlying Properties, certain of
such charges and interest will be deducted in calculating NPI Net Proceeds for
the quarter in which the charges are paid and in each quarter thereafter until
the full amount of the additional royalty charges and interest have been
recovered.

     The Trust is subject to certain rules of the Bureau of Land Management
under which the holding of interests in leases by persons other than citizens,
nationals and legal resident aliens of the United States ("Eligible Citizens")
may be limited. As a result, non-Eligible Citizens may be prohibited from owning
Units. If any Units are acquired by persons or entities not constituting
Eligible Citizens, such Unitholders may be

                                       30
<PAGE>   34

required to sell such Units pursuant to a procedure set forth in the Trust
Agreement. See "Item 1 -- Description of Units -- Possible Divestiture of
Units."

SALE AND ABANDONMENT OF UNDERLYING PROPERTIES

     BROG does not have the right to abandon its interest in any well on the
Underlying Properties. However, BROG does not have control over any decisions
which may be made by the operator and other working interest owners of the
Underlying Properties to abandon any well or property on the Underlying
Properties (although BROG does exercise influence over such decisions to the
extent of its working interest). Since BROG does not operate any of the wells on
the Underlying Properties (although BROG operates a single communitized well),
BROG does not normally control the timing of plugging and abandoning wells. The
Conveyance provides that BROG's working interest share of the costs of plugging
and abandoning uneconomic wells will be deducted in calculating NPI Net Proceeds
or Infill Net Proceeds, as the case may be.

     BROG may sell its interest in the Underlying Properties, subject to and
burdened by the Royalty Interests, without the consent of the Trust or the
Unitholders. Any purchaser of such interest will be subject to the same
standards, and will possess the same influence, set forth in the preceding
paragraph. Under the Trust Agreement, BROG has certain rights (but not the
obligation) to purchase the Royalty Interests upon termination of the Trust. See
"Item 1 -- Description of the Trust -- Termination and Liquidation of the
Trust."

THE INFILL NPI

     The Royalty Interests include the Infill NPI, a net profits interest in any
Infill Wells completed on the Underlying Properties. No Infill Wells have been
drilled and none will be drilled unless, prior to any decision to drill any such
wells by the working interest owners of the Underlying Properties, the well
spacing limitations for coal seam wells in the San Juan Basin are reduced. If
such changes occur and Infill Wells are drilled, the Infill NPI will entitle the
Trust to receive 20 percent of the Infill Net Proceeds. No reserves have been
attributed in the December 31, 1997 Reserve Report or the Prior Reserve Reports
to any Infill Wells.

     The Trustee has been advised by Burlington Resources that it believes,
although no assurances are given, that Infill Wells will be drilled on the
Underlying Properties only if the owners of the working interests in such
properties believe that the expenditures required to drill and complete such
Infill Wells will be justified by the expected increase in recoverable reserves
therefrom. Infill Wells may recover a portion of the reserves producible from
wells burdened by the NPI. Accordingly, the drilling of Infill Wells may reduce
the proved reserves attributable to wells burdened by the NPI, although
Burlington Resources has advised the Trustee that it believes that such
reduction will be offset, at least in part, by the reserves then attributable to
such Infill NPI. Because the NPI generally entitles the Trust to 95 percent of
the NPI Net Proceeds and the Infill NPI entitles the Trust to only 20 percent of
the Infill Net Proceeds, no assurance can be given that amounts payable to the
Trust will not be reduced if Infill Wells are drilled. Further, under current
law no Section 29 tax credits will be available with respect to production
attributable to the Infill NPI even if an Infill Well recovers a portion of the
reserves that qualified for Section 29 tax credits because prior to the drilling
and completion of such Infill Well, they were recoverable from a well burdened
by the NPI.

     BROG's working interest share of capital expenditures and operating
expenses relating to any Infill Wells will be deducted in calculating the Infill
Net Proceeds. Such amounts bear no relation to capital and operating costs which
will be deducted in calculating the NPI Net Proceeds. See " -- The NPI." During
the term of the Trust, BROG will account for each of the NPI and the Infill NPI
separately, with the result that no amounts deductible in calculating the NPI
Net Proceeds will be deducted from the Infill NPI revenue stream, and vice
versa. If, during any period, costs and expenses (including interest expenses)
deductible in calculating the portion of the Infill Net Proceeds payable to the
Trust exceed gross proceeds with respect to Infill Wells, neither the Trust nor
Unitholders will be liable for such excess, but the Trust will receive no
payments for distribution to Unitholders with respect to the Infill NPI until
future gross proceeds with respect to such wells exceed future costs and
expenses with respect thereto plus the cumulative excess of such costs and
expenses plus interest thereon at Citibank's Base Rate.

BURLINGTON RESOURCES' PERFORMANCE ASSURANCES

     Pursuant to the Trust Agreement, Burlington Resources has agreed to pay
each of the following to the extent not paid by BROG when due and payable: (i)
all liabilities and capital and lease operating expenses which BROG is required
under the Conveyance to pay as a working interest owner of the Underlying
Properties; (ii) all NPI Net Proceeds, Infill Net Proceeds and other amounts
which BROG is obligated to pay to the Trust under the Conveyance; (iii) any
proceeds from a sale of any remaining Royalty Interests that BROG may elect to
purchase upon termination of the Trust; and (iv) certain indemnification
obligations relating to environmental liabilities in connection with BROG's
interest in the Underlying Properties (collectively, "BROG Payment
Obligations"). Burlington Resources has also agreed to pay, to the extent not
paid by BRTI when due and payable, all amounts which BRTI is required to pay to
BROG in respect of production attributable to the Royalty Interests pursuant to
the terms of the Gas Purchase Contract ("BRTI Payment Obligations"). Burlington
Resources may assign such performance assurance obligations, and may be relieved
of such obligations, upon the occurrence of certain events and to an entity or
entities meeting certain criteria.

TITLE TO PROPERTIES

     Burlington Resources has advised the Trustee that it believes that BROG's
title to its interest in the Underlying Properties is, and the Trust's title to
the Royalty Interests is, good and defensible in accordance with standards
generally accepted in the gas industry, subject to such exceptions which, in the
opinion of Burlington Resources, are not so material as to detract substantially
from the use or value of BROG's interest in the Underlying Properties or the
Royalty Interests.

     The Underlying Properties are typically subject, in one degree or another,
to one or more of the following: (i) royalties and other burdens and
obligations, expressed and implied, under oil and gas leases; (ii) overriding
royalties and other burdens created by BROG or its predecessors in title; (iii)
a variety of contractual obligations (including, in some cases, development
obligations) arising under operating agreements, farmout agreements, production
sales contracts and other agreements that may affect the properties or their
titles; (iv) liens that arise in the normal course of operations, such as those
for unpaid taxes, statutory liens securing unpaid suppliers and contractors and
contractual liens under operating agreements; (v) pooling, unitization and
communitization agreements, declarations and orders; (vi) irregularities or
ambiguities in the instruments of title; and (vii) easements, restrictions,
rights-of-way and other matters that commonly affect property. To the extent
that such burdens and obligations affect BROG's rights to production and the
value of production from the Underlying Properties, they have been taken into
account in calculating the Trust's interests and in estimating the size and
discounted net present value of the reserves attributable to the Royalty
Interests. Except as noted below, Burlington Resources believes that the burdens
and obligations affecting BROG's interest in the Underlying Properties and
Royalty Interests are conventional in the industry for similar properties, do
not, in the aggregate, materially interfere with the use of the Underlying
Properties and will not materially and adversely affect the discounted net
present value of the Royalty Interests.

     Although the matter is not entirely free from doubt, Burlington Resources
has advised the Trustee that it believes (based upon the opinions of local
counsel to Burlington Resources with respect to matters of New Mexico law) that
the Royalty Interests should constitute property interests under applicable
state law. Consistent therewith, the Conveyance states that the Royalty
Interests constitute property interests and it was recorded in the appropriate
real property records of San Juan and Rio Arriba counties, New Mexico, the
counties in which the Underlying Properties are located, in accordance with
local recordation provisions. If, during the term of the Trust, BROG becomes
involved as a debtor in bankruptcy proceedings under the Federal Bankruptcy
Code, it is not entirely clear that all of the Royalty Interests would be
treated as property interests under the laws of New Mexico. If in such a
proceeding a determination were made that the Royalty Interests constitute
property interests, the Royalty Interests should be unaffected in any material
respect by such bankruptcy proceeding. If in such a proceeding a determination
were made that the Royalty Interests constitute executory contracts (a term
used, but not defined, in the Federal Bankruptcy Code to refer to a contract
under which the obligations of both the debtor and the other party to such
contract are so unsatisfied that the failure of either to complete performance
would constitute a material breach excusing performance by
                                       32
<PAGE>   36

the other) and not a property interest under applicable state law, and if such
contract were not to be assumed in a bankruptcy proceeding involving BROG, the
Trust would be entitled to damages for breach of such contract covered by the
termination of such contract in such bankruptcy proceeding and, with respect to
such entitlement, the Trust would be treated as an unsecured creditor of BROG in
the pending bankruptcy. Although no assurance is given, Burlington Resources
does not believe that the Royalty Interests should be subject to rejection in a
bankruptcy proceeding as executory contracts.

ITEM 7. TRUSTEE'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS.

     The Trust makes quarterly cash distributions 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. The Royalty Interests owned by the Trust burden the net
revenue interest in the Underlying Properties that is owned by BROG 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 until its subsequent distribution to
Unitholders.

     The amount of distributable income of the Trust for any calendar year may
differ from the amount of cash available for distribution to the Unitholders in
such year 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 paid or reserves are established for them. Consequently, the
reported distributable income of the Trust for any year is determined by
deducting from the income received by the Trust the amount of expenses paid by
the Trust during such year. 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 adjustment
for changes in reserves for unpaid liabilities. See Note 5 to the financial
statements of the Trust appearing elsewhere in this Form 10-K for additional
information regarding the determination of the amount of cash available for
distribution to Unitholders.

     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 BROG'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. For additional information concerning the
reserves please refer to Note 9 "Supplemental Oil and Gas Information" of the
financial statements.

     The year 1997 marked the fourth full year of operations for the Trust.
Royalty income for 1997 was $6,270,303 as compared to $10,671,428 for 1996 and
$14,076,780 for 1995. Production of 10,389,400 Mcf for 1997 declined from
12,122,587 Mcf for 1996 and 14,212,659 Mcf for 1995 due to the natural decline
of production from the coal seam formation. Natural gas prices received for 1997
were $1.00 per Mcf compared to $1.06 per Mcf for 1996 and $1.08 per Mcf for
1995. During 1997, 1996 and 1995, the Trust was charged $2,108,110, $1,037,445,
and $240,702, respectively, of capital costs related to various capital projects
such as installation of gas gathering loop systems on specific units. The
Royalty income presented for those years is net of these capital expenditures.
While future capital expenditures are expected, these costs are expected to be
at lower levels in future years.

     Royalty income received by the Trust in a given calendar year will
generally reflect the proceeds from the sale of gas produced from the Underlying
Properties during the first three quarters of that year and the fourth quarter
of the preceding calendar year less any operating and capital costs.
Accordingly, the royalty income included in distributable income for the years
ended December 31, 1997, 1996 and 1995 was based on production volumes and
natural gas prices for the twelve months ended September 30, 1997, 1996 and
1995, respectively, in accordance with the terms of the conveyance of the
Royalty Interests to the Trust, as shown in the table below. The production
volumes included in the table are actual net production volumes attributable

                                       34
<PAGE>   38

to BROG's interest in the Underlying Properties, and not production attributable
to the Royalty Interests owned by the Trust.

     At December 31, 1995 and 1994, the Trust's net carrying value of its
investment in royalty interests exceeded the sum of the future net cash flows
plus the estimated future Section 29 tax credit benefits from the production of
the Trust's reserves by $561,809 and $995,048, respectively. Accordingly, the
Trust was required to record an impairment allowance in 1995 and 1994 to reduce
its carrying value of royalty interests in gas reserves. The reduction in the
carrying value of its investments was charged directly to trust corpus. For
further discussion of impairment, please refer to Notes 2 and 10 in the
financial statements. There was no impairment writedown required to be recorded
in 1996 or 1997. Trust management routinely reviews its royalty interests in oil
and gas properties for impairment whenever events or circumstances indicate that
the carrying amount of an asset may not be recoverable. If an impairment event
occurs and it is determined that the carrying value of the Trust's royalty
interests may not be recoverable, an impairment will be recognized as measured
by the amount by which the carrying amount of the royalty interests exceeds the
fair value of these assets, which would likely be measured by discounting
projected cash flows. Should the aggregate dollar amount of the Trust's reserves
and Section 29 credits decline, an additional impairment provision, which could
be material, will be required. There can be no assurance such a writedown will
not occur.

     Production attributable to BROG's interest in the Underlying Properties is
generally sold pursuant to a gas purchase contract between BROG and Burlington
Resources Trading Inc. ("BRTI"). The gas purchase contract provides certain
protections in the form of price credits for Unitholders when the applicable
Blanco Hub Spot Price falls below $1.65 per MMBtu and provides certain benefits
for BRTI when the Blanco Hub Spot Price exceeds $2.10 per MMBtu. The gas
purchase contract also provides that the price paid for gas by BRTI is reduced
by the amount of gathering and/or transportation charges, taxes, treating and
processing costs and all other costs in connection with such services from the
central gathering point to main line delivery paid by BRTI. For more detailed
information regarding the terms and conditions of the gas purchase contract, see
"Item 2. Properties -- Gas Purchase Contract."

     The Blanco Hub Spot Price was above $1.65 per MMBtu for all months of 1997
except March and April 1997, resulting in a net reduction in the Price Credit
Account of approximately $3.3 million. The Blanco Hub Spot Price was below $1.65
per MMBtu for all months during 1996 except August, November and December and
was below such price in each month during 1995. However, pursuant to the terms
of the gas purchase contract, BRTI continued to purchase gas attributable to
BROG's interest in the Underlying Properties at the $1.60 per MMBtu minimum
purchase price, less deductible costs paid by BRTI, established by the gas
purchase contract; and BRTI received a price credit from BROG for each MMBtu of
natural gas so purchased by BRTI equal to the difference between the $1.60 per
MMBtu minimum purchase price and the applicable index price (which price is
equal to 97 percent of the applicable Blanco Hub Spot Price). BRTI estimates
that, as of December 31, 1997, BRTI had aggregate price credits of approximately
$5.6 million of which the Trust's 95 percent interest was approximately $5.3
million. The Blanco Hub Spot Price was above $1.65 per MMBtu in January and
February 1998. With the Blanco Hub Spot Price being above the minimum purchase
price for several months of 1997, BRTI accrued additional price credits of $.2
million and recouped

                                       35
<PAGE>   39

price credits totaling $3.5 million for a net reduction in the price credit of
$3.3 million. The entitlement of BRTI to recoup the price credits means that if
and when the applicable Blanco Hub Spot Price is above $1.65 per MMBtu, future
royalty income paid to the Trust would be reduced until such time as all accrued
and unrecouped price credits have been recovered by BRTI. Corresponding cash
distributions to Unitholders would also be reduced.

     General and Administrative Expenses remained relatively stable for 1997
compared to 1996 and 1995. For the years ended December 31, 1997, 1996 and 1995,
General and Administrative Expenses totaled $664,555, $659,226 and $711,959
respectively.

YEAR 2000

     Many existing computer programs use only two digits to identify a year in
the date field. These programs were designed and developed without considering
the impact of the upcoming change in the century. If not corrected, many
computer applications could fail or create erroneous results by or at the Year
2000. The Year 2000 issue affects virtually all companies and organizations. If
a company or organization does not successfully address its Year 2000 issues, it
may face material adverse consequences.

     The Trust is reliant on the performance of BROG and third party vendors for
the receipt of Royalty income, payment of expenses and disbursement of
distributable income. The Trustee can provide no assurance as to whether BROG
and third party vendors will successfully address the Year 2000 issue. Any
failure by BROG or any of the third party vendors to successfully address the
Year 2000 issue could have a material adverse impact on the Trust and its
Unitholders.

TENDER OFFERS

     On January 20, 1998, the parties listed in the Security Ownership of
Certain Beneficial Owners table (the "Ownership Table") set forth in Item 12 of
this Form 10-K (such parties, collectively, "San Juan") filed a Schedule 14D-1
with the Securities and Exchange Commission in connection with a tender offer to
purchase exactly (and not less than) 5,446,860 Units. On February 13, 1998, a
Schedule 14D-1 was filed in connection with a separate tender offer by another
party to purchase any and all Units. These tender offers expired on February 17,
1998 and March 13, 1998, respectively.

     Following the expiration of its tender offer, San Juan has acquired through
a series of open market transactions additional Units resulting in total
holdings as set forth in the Ownership Table. According to the Offer to Purchase
filed by San Juan as an exhibit to its Schedule 14D-1, the purpose of San Juan's
tender offer was to acquire 67% of the outstanding Units so that it could affect
a vote to terminate the Trust, causing a liquidation of the Trust's assets and a
resulting distribution to Unitholders (see "Item 1 -- Description of the
Trust -- Termination and Liquidation").

FORWARD-LOOKING STATEMENTS

     This Form 10-K includes "forward-looking statements" within the meaning of
Section 21E of the Securities Exchange Act of 1934, which are intended to be
covered by the safe harbor created thereby. All statements other than statements
of historical fact included in this Form 10-K are forward-looking statements.
Such statements include, without limitation, certain reserve information and
other statements contained in Item 2, "Properties", and certain statements
regarding the Trust's financial position, industry conditions and other matters
contained in "Trustee's Discussion and Analysis" in this Item 7. Although the
Trustee believes that the expectations reflected in such forward-looking
statements are reasonable, such expectations are subject to numerous risks and
uncertainties and the Trustee can give no assurance that they will prove
correct. There are many factors, none of which is within the Trustee's control,
that may cause such expectations not to be realized, including, among other
things, factors identified in this Form 10-K affecting oil and gas prices and
the recoverability of reserves, general economic conditions, actions and
policies of petroleum-producing nations and other changes in the domestic and
international energy markets.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA.

                          INDEPENDENT AUDITORS' REPORT

NationsBank of Texas, N.A.,
as Trustee of Burlington Resources Coal Seam Gas Royalty Trust

     We have audited the accompanying statements of assets, liabilities and
trust corpus of Burlington Resources Coal Seam Gas Royalty Trust as of December
31, 1997 and 1996, and the related statements of distributable income and
changes in trust corpus for each of the three years in the period ended December
31, 1997. These financial statements are the responsibility of the Trustee. Our
responsibility is to express an opinion on these financial statements based on
our audits.

     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our 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.

     In our opinion, the financial statements referred to above present fairly,
in all material respects, the assets, liabilities and trust corpus of Burlington
Resources Coal Seam Gas Royalty Trust at December 31, 1997, and 1996, and the
distributable income and changes in trust corpus for each of the three years in
the period ended December 31, 1997, on the basis of accounting described in Note
2.

1. TRUST ORGANIZATION AND PROVISIONS

     Burlington Resources Coal Seam Gas Royalty Trust (the "Trust") was formed
as a Delaware business trust pursuant to the terms of the Trust Agreement of
Burlington Resources Coal Seam Gas Royalty Trust (the "Trust Agreement") entered
into effective as of May 1, 1993 by and among Burlington Resources Oil & Gas
Company, a Delaware corporation ("BROG"), as trustor, Burlington Resources Inc.,
a Delaware corporation ("Burlington Resources"), and NationsBank of Texas, N.A.,
a national banking association (the "Trustee"), and Mellon Bank (DE) National
Association, a national banking association (the "Delaware Trustee"), as
trustees. The trustees are independent financial institutions.

     The Trust is a grantor trust formed to acquire and hold certain net profits
interests (the "Royalty Interests") in BROG's interest in the Fruitland coal
formation underlying the Northeast Blanco Unit in the San Juan Basin of New
Mexico (the "Underlying Properties"). The Trust was initially created by the
filing of a Certificate of Trust with the Secretary of State of Delaware on May
5, 1993. In accordance with the Trust Agreement, BROG contributed $1,000 as the
initial trust corpus of the Trust. On June 17, 1993, the Royalty Interests were
conveyed to the Trust by BROG pursuant to the Net Profits Interest Conveyance
(the "Conveyance") dated effective as of May 1, 1993, in consideration for all
8,800,000 authorized units of beneficial interest ("Units") in the Trust. BROG
transferred its Units by dividend to its parent, Burlington Resources, Inc.,
which transferred such Units by dividend to its parent, Burlington Resources,
which sold such Units to the public through various underwriters in June 1993
(the "Public Offering"). All of the production attributable to the Underlying
Properties is from the Fruitland coal formation and currently constitutes "coal
seam" gas that entitles the owners of such production, provided certain
requirements are met, to tax credits pursuant to Section 29 of the Internal
Revenue Code of 1986, as amended.

     Royalty income to the Trust is attributable to the sale of depleting
assets. All of the Underlying Properties burdened by the NPI (as hereinafter
defined) consist of producing properties. Accordingly, the proved reserves
attributable to BROG'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.

     The Trustee has all powers to collect and distribute 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 or are required by law
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 or BROG's interest therein.

     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 are distributed to the 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. The Royalty Interests consist primarily
of a net profits interest (the "NPI") in BROG's interest in the Underlying
Properties. The NPI generally entitles the Trust to receive 95 percent of the
NPI Net Proceeds, as defined below. The Royalty Interests also include a 20
percent interest in the 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 in the Northeast Blanco Unit ("Infill
Wells") during the term of the Trust. With respect to the NPI, the term "NPI Net
Proceeds" generally means the aggregate proceeds attributable to BROG's net
revenue interest in the Underlying Properties (excluding the proceeds, if any,
from Infill Wells) calculated at the price paid by BRTI at any one of four
central delivery points in the Northeast Blanco Unit gathering system or either
of two wellhead delivery points (collectively, the "Central Gathering Point")
for the entitled volume of gas produced and sold from BROG's interest in the
Underlying Properties less BROG's working interest share

                                       39
<PAGE>   43

of (i) property, production and related taxes (including severance taxes); (ii)
lease operating expenses; (iii) capital costs (if paid after January 1, 1994);
(iv) royalties, if any, required to be paid that are based on the value of
Section 29 tax credits attributable to such working interest share; and (v)
interest on the unrecovered portion, if any, of the foregoing costs at a rate
equal to the base rate (compounded quarterly) as announced from time to time by
Citibank, N.A. ("Citibank's Base Rate"). The term "Infill Net Proceeds"
generally means the aggregate proceeds attributable to BROG's net revenue
interest calculated at the price paid by BRTI at the Central Gathering Point for
the entitled volume of gas produced and sold from BROG's interest in any Infill
Wells less BROG's working interest share of (a) property, production and related
taxes (including severance taxes) on such Infill Wells; (b) lease operating
expenses with respect to such Infill Wells; (c) capital costs with respect to
such Infill Wells; and (d) interest on the unrecovered portion, if any, of the
foregoing costs at Citibank's Base Rate. The complete definitions of NPI Net
Proceeds and Infill Net Proceeds are set forth in the Conveyance.

     Because of the passive nature of the Trust and the restrictions and
limitations on the powers and activities of the Trustee contained in the Trust
Agreement, the Trustee does not consider any of the officers and employees of
the Trustee to be "officers" or "executive officers" of the Trust as such terms
are defined under the applicable rules and regulations adopted under the
Securities Exchange Act of 1934.

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:

     - Royalty income and interest income are recorded in the period in which
       amounts are received by the Trust rather than in the months of
       production.

     - General and administrative expenses recorded are based on liabilities
       paid and cash reserves established out of cash received.

     - Amortization of the Royalty Interests is calculated on a
       unit-of-production basis and charged directly to trust corpus based upon
       when revenues are received.

     - Distributions to Unitholders are recorded when declared by the Trustee
       (see Note 5).

     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, general and administrative expenses recorded are based on
liabilities paid and cash reserves established rather than on an accrual basis,
and amortization and impairment of the Royalty Interests is not charged against
operating results.

     Burlington Resources sold an aggregate of 8,800,000 Units in the Public
Offering. Accordingly, the carrying value of the Trust's Royalty interest in oil
and gas properties at December 31, 1997 and 1996 reflect 8,800,000 Units at the
public offering price of $20.50 per Unit, less accumulated amortization and
impairment.

USE OF ESTIMATES

     The preparation of financial statements in conformity with the basis of
accounting described above requires management to make estimates and assumptions
that affect reported amounts of certain assets, liabilities, revenues and
expenses as of and for the reporting periods. Actual results may differ from
such estimates.

IMPAIRMENT

     Trust management routinely reviews its royalty interests in oil and gas
properties for impairment whenever events or circumstances indicate that the
carrying amount of an asset may not be recoverable. The net amount of royalty
interests in gas properties is limited to the sum of the future net cash flows
attributable

                                       40
<PAGE>   44

to the Trust's gas reserves at year end using current product prices plus the
estimated future Section 29 credits for federal income tax purposes. If the net
cost of royalty interests in gas properties exceeds this amount, an impairment
provision is recorded and charged to the trust corpus.

     If an impairment event occurs and it is determined that the carrying value
of the Trust's royalty interests may not be recoverable, an impairment will be
recognized as measured by the amount by which the carrying amount of the royalty
interests exceeds the fair value of these assets, which would likely be measured
by discounting projected cash flows. Should the aggregate dollar amount of the
Trust's reserves and Section 29 credits decline, an additional impairment
provision, which could be material, will be required. There can be no assurance
such a writedown will not occur.

NEW ACCOUNTING STANDARDS

     The Trust has adopted the new computation and disclosure requirements of
Statement of Financial Accounting Standards ("SFAS") No. 128 -- "Earnings Per
Share." Basic earnings per share is computed by dividing net income by the
weighted average shares outstanding. Earnings per share assuming dilution is
computed by dividing net income by the weighted average number of shares and
equivalent shares outstanding. The Trust had no equivalent shares outstanding
for any period presented and accordingly, the adoption of SFAS No. 128 had no
impact on previously reported distributable income per unit. Basic and assuming
dilution distributable income per Unit are the same.

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 share of
income attributable to the Royalty Interests consistent with the Unitholder's
method of accounting 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. RELATED PARTY TRANSACTIONS

     Burlington Resources provides accounting, bookkeeping and informational
services to the Trust in accordance with an Administrative Services Agreement
effective May 1, 1993. The fee is $75,000 per quarter, adjusted annually, based
upon the change in the Producer's Price Index each January 1 commencing January
1, 1994. Aggregate fees paid by the Trust to Burlington Resources in 1997, 1996
and 1995 were $322,877, $313,157 and $305,695, respectively.

     Aggregate fees paid by the Trust to the Trustee in 1997, 1996 and 1995 were
$39,699, $39,147 and $38,192, respectively. The Delaware Trustee was paid a flat
fee of $10,000 for each of the respective years.

     BROG's production from the Underlying Properties is gathered, treated and
processed under the terms of the Gas Gathering, Dehydrating and Treating
Agreement between BROG and Burlington Resources Gathering Inc. ("BRGI") dated
May 3, 1990, as amended May 1, 1993 ("Gas Gathering, Dehydrating and Treating
Agreement"). The fees charged by BRGI to BROG totaled approximately $3.9
million, $4.1 million, and $4.8 million for the calendar years ended December
31, 1997, 1996, and 1995, respectively, and are in accordance with the rates
defined in the Gas Gathering Dehydrating and Treating Agreement.  These fees are
deducted in arriving at the net revenues of the Underlying Properties.

5. 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 before the last business day before the 50th day following the end of each
calendar quarter from the Royalty Interests attributable to production during
such quarter, plus, with certain

                                       41
<PAGE>   45

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 63rd 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 on or prior to the 75th day 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.

     The Royalty Interests may be sold under certain circumstances and will be
sold following termination of the Trust. A special distribution will be made of
undistributed net sales proceeds and other amounts received by the Trust
aggregating in excess of $10,000,000 (a "Special Distribution Amount"). 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 prior to 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.

6. CONTINGENCIES

     Under the terms of the gas purchase contract entered into between BROG and
an affiliate of BROG (the "Gas Purchase Contract"), additional revenues may be
paid to the Trust to meet the minimum purchase price provision of $1.60 per
MMBtu (the "Minimum Purchase Price") (less applicable deductions). This
additional revenue is subject to recoupment by BROG from future revenues
received from production, with respect to any month commencing after December
31, 1993, when the applicable index price in such month exceeds the Minimum
Purchase Price.

     The applicable index price was above the Minimum Purchase Price during 1997
except for March and April of 1997 resulting in a net reduction in the Price
Credit Account of $3.3 million. The applicable index price was below the Minimum
Purchase Price during 1996 except for the months of August, November and
December, and in each month during 1995. Pursuant to the terms of the Gas
Purchase Contract, BRTI established a price credit account. BRTI estimates that,
as of December 31, 1997, BRTI had aggregate price credits in the price credit
account of approximately $5.6 million of which the Trust's 95 percent interest
was approximately $5.3 million. The applicable index price was above the Minimum
Purchase Price in January and February 1998.

     The Trustee has been advised by BROG that the Minerals Management Service
("MMS"), a subagency of the U.S. Department of the Interior, has from time to
time considered the inclusion of the value of the Section 29 tax credits
attributable to coal seam gas production in the calculation of gross proceeds
for purposes of calculating the royalty that is payable to the MMS. On August
31, 1993, the U.S. Office of the Inspector General (the "OIG") issued an audit
report stating the view that Section 29 tax credits should be included in the
calculation of gross proceeds and recommended that the MMS pursue collection of
additional royalties with respect to past and future production. On December 8,
1993, however, the Office of the Solicitor of the U.S. Department of the
Interior gave its opinion to the MMS that the report of the OIG was incorrect
and that Section 29 tax credits are not part of gross proceeds for the purpose
of Federal royalty calculations. BROG believes that any inclusion of the value
of Section 29 tax credits for purposes of calculating royalty payments required
to be made on Federal lands would be inappropriate since all mineral interest
owners, including royalty owners, are entitled to Section 29 tax credits for
their proportionate share of qualifying coal seam gas production. BROG has
advised the Trustee that it would vigorously oppose any attempt by the MMS to
require the inclusion of the value of Section 29 tax credits in the calculation
of gross proceeds. However, if such regulations were adopted and upheld, royalty
payments would be increased which would decrease NPI Net Proceeds and,
therefore, amounts payable to the Trust. The reduction in amounts payable

                                       42
<PAGE>   46

to the Trust would cause a corresponding reduction in associated Section 29 tax
credits available to Unitholders.

     BROG produced and sold more gas than its entitled share based upon its
working interest in the Underlying Properties, and thus is in an overproduced
position of approximately 29 million cubic feet ("MMcf"), 297 MMcf, and 258 MMcf
as of December 31, 1997, 1996, and 1995, respectively.

     Per the terms of the Gas Purchase Contract, all royalty income of the Trust
was derived from BROG.

7. SUBSEQUENT EVENTS

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

     The Trustee has estimated the Section 29 tax credit associated with the
March 16, 1998 quarterly distribution to be $.20 per Unit (unaudited.)

     Subsequent to December 31, 1997, two tender offers were made to purchase
outstanding Units held by Unitholders (see "Item 12 -- Security Ownership of
Certain Beneficial Owners and Management").

     Due to the significant upward revision in estimated reserve quantities (see
Note 9) estimated amortization of royalty interests was adjusted downward by
approximately $1.7 million during the fourth quarter of 1997. This adjustment
did not have an impact on the Trust's distributable income.

9. SUPPLEMENTAL OIL AND GAS INFORMATION (UNAUDITED)

     The net proved reserves attributable to the Royalty Interests, all located
within the United States, have been estimated as of December 31, 1997, 1996 and
1995 and January 1, 1995 by independent petroleum engineers.

     In accordance with Statement of Financial Accounting Standards No. 69,
estimates of future net revenues from proved reserves have been prepared either
using end-of-period or contractual gas prices as appropriate and related costs.
The standardized measure of future net revenues from the gas reserves is
calculated based on discounting such future net revenues at an annual rate of 10
percent. At December 31, 1997, the price the Trust was entitled to receive under
the Gas Purchase Contract was $2.07 per MMBtu subject to accrued and unrecouped
price credits (see Note 6). For purposes of preparation of the reserve report as
of December 31, 1997, however, the price was held constant at the minimum
purchase price ($1.60 per MMBtu) until the accrued price credits were recouped,
after which the $2.07 per MMBtu price was utilized for the remaining life of the
Royalty Interests.

     Numerous uncertainties are inherent in estimating volumes and value of
proved developed reserves and in projecting future production rates. Such
reserve estimates are subject to change as additional information becomes
available. The reserves actually recovered and the timing of production may be
substantially different from the original estimates.

     The reserve estimates for the Royalty Interests are based on a percentage
share of NPI Net Proceeds payable to the Trust of 95 percent. A net profits
interest does not entitle the Trust to a specific quantity of gas but to a
portion of gas sufficient to yield a specified portion of the net proceeds
derived therefrom. Proved reserves attributable to a net profits interest are
calculated by deducting an amount of gas sufficient, if sold at the prices used
in preparing the reserve estimates for such profits interest, to pay the future
established costs and expenses deducted in the calculation of the net proceeds
of such interest. Accordingly, the reserves presented for the Royalty Interests
reflect quantities of gas that are free of future costs and expenses if the
price and cost assumptions used in the reserve report prepared as of December
31, 1997 occur.

     All proved reserve estimates presented above are proved developed.

     Proved reserves are estimated quantities of natural gas which geological
and engineering data indicate with reasonable certainty to be recoverable in
future years from known reservoirs under existing economic and operating
conditions. Proved developed reserves are proved reserves which can be expected
to be recovered through existing wells with existing equipment and operating
methods.

     The above reserves do not include undiscounted Section 29 tax credits of
approximately $31,572,000 as estimated by an independent petroleum engineer. The
present discounted (10%) value of these tax credits is approximately
$25,890,000.

     Subsequent to year end 1997, the prices of gas decreased slightly. As of
March 18, 1998, published natural gas prices were approximately $2.01 per MMBtu
as compared to prices utilized in the Trust's calculation of its year end
standardized measure of discounted future net cash flow. The use of prices
currently being received would result in a lower standardized measure of
discounted future net cash flows.

10. IMPAIRMENT OF ROYALTY INTERESTS

     At December 31, 1995, the Trust's net carrying value of its investment in
royalty interests exceeded the sum of the future net cash flows plus the
estimated future Section 29 tax credit benefits from the production of the
Trust's reserves by $561,809. Accordingly, the Trust was required to record an
impairment allowance during 1995 to reduce its carrying value of royalty
interests in gas reserves. The reduction in the carrying value of its
investments was charged directly to trust corpus. There was no impairment
writedown required to be recorded in 1996 or 1997. Trust management routinely
reviews its long lived assets for impairment whenever events or circumstances
indicate that the carrying amount of an asset may not be recoverable. If an
impairment event occurs and it is determined that the carrying value of the
Trust's royalty interests may not be recoverable, an impairment will be
recognized as measured by the amount by which the carrying amount of the royalty
interests exceeds the fair value of these assets, which would likely be measured
by discounting projected cash flows. Should the aggregate dollar amount of the
Trust's reserves and Section 29 credits decline, an additional impairment
provision, which could be material, will be required. There can be no assurance
such a writedown will not occur.

                                    PART III

ITEM 10. DIRECTORS AND EXECUTIVE OFFICERS OF THE REGISTRANT.

     The Trust has no directors or executive officers. Each of the Trustee and
the Delaware Trustee is a corporate trustee that may be removed as trustee under
the Trust Agreement, with or without cause, at a meeting duly called and held by
the affirmative vote of Unitholders of not less than a majority of all the Units
then outstanding. Any such removal of the Delaware Trustee shall be effective
only at such time as a successor Delaware Trustee fulfilling the requirements of
Section 3807(a) of the Delaware Code has been appointed and has accepted such
appointment, and any such removal of the Trustee shall be effective only at such
time as a successor Trustee has been appointed and has accepted such
appointment.

ITEM 11. EXECUTIVE COMPENSATION.

     The following is a description of certain fees and expenses anticipated to
be paid or borne by the Trust, including fees expected to be paid to Burlington
Resources, the Trustee, the Delaware Trustee, the Transfer Agent, or their
affiliates.

     Ongoing Administrative Expenses. The Trust is responsible for paying all
legal, accounting, engineering and stock exchange fees, printing costs and other
administrative and out-of-pocket expenses incurred by or at the direction of the
Trustee or Delaware Trustee and the out-of-pocket expenses of the Transfer
Agent.

     Compensation of the Trustee, Delaware Trustee and Transfer Agent. The Trust
Agreement provides for compensation to the Trustee and the Delaware Trustee for
administrative services, out of the Trust assets. The Trustee was paid a 1997
base amount of $39,699, plus an hourly charge for services in excess of a
combined total of 300 hours annually at the Trustee's then standard rate. The
Trustee received total compensation for 1997 of $39,699. The Trustee's annual
base fee escalates at the rate of 3 percent per year. The Delaware Trustee is
paid a fixed annual amount of $10,000. The Trustee and the Delaware Trustee are
each entitled to reimbursement for out-of-pocket expenses. Upon termination of
the Trust, the Trustee will receive, in addition to its out-of-pocket expenses,
a termination fee in the amount of $10,000. If a trustee resigns and a successor
has not been appointed in accordance with the terms of the Trust Agreement
within 210 days after the notice of resignation is received, the fees payable to
that trustee will increase significantly until a new trustee is appointed.

     The Transfer Agent receives a transfer agency fee of $5.30 annually per
account (minimum of $15,000 annually), subject to increase or decrease each
December, based upon the change in the Producers' Price Index as published by
the Department of Labor, Bureau of Labor Statistics, plus $1.00 for each
certificate issued in excess of 10,000 annually. The total of fees paid by the
Trust to the Transfer Agent in 1997 was $7,384.

     Fees to Burlington Resources. Burlington Resources will receive throughout
the term of the Trust, an administrative services fee for accounting,
bookkeeping and other administrative services relating to the Royalty Interests
as described below in "Item 13 -- Administrative Services Agreement".

     On January 20, 1998, the parties listed in the above Security Ownership of
Certain Beneficial Owners table (collectively, "San Juan") filed a Schedule
14D-1 with the Securities and Exchange Commission in connection with a tender
offer to purchase exactly (and not less than) 5,446,860 Units. On February 13,
1998, a Schedule 14D-1 was filed in connection with a separate tender offer by
another party to purchase any and all Units. These tender offers expired on
February 17, 1998 and March 13, 1998, respectively.

     Following the expiration of its tender offer, San Juan has acquired through
a series of open market transactions additional Units resulting in total
holdings as set forth in the above table. According to the Offer to Purchase
filed by San Juan as an exhibit to its Schedule 14D-1, the purpose of San Juan's
tender offer was to acquire 67% of the outstanding Units so that it could effect
a vote to terminate the Trust, causing a liquidation of the Trust's assets and a
resulting distribution to Unitholders (see "Item 1 -- Description of the
Trust -- Termination and Liquidation").

     (b) Security Ownership of Management. The Trust has no directors or
executive officers. As of March 13, 1998, NationsBank of Texas, N.A., the
Trustee, did not beneficially own any Units. As of March 13, 1998, Mellon Bank
(DE) National Association, the Delaware Trustee, did not beneficially own any
Units.

     (c) Changes in Control. The Trustee knows of no arrangements the operation
of which may at a subsequent date result in a change in control of the Trust.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS.

ADMINISTRATIVE SERVICES AGREEMENT

     Pursuant to the Trust Agreement, Burlington Resources and the Trust entered
into an Administrative Services Agreement effective May 1, 1993. A copy of the
Administrative Services Agreement is filed as an exhibit to this Form 10-K.

     The Administrative Services Agreement obligates the Trust to pay to
Burlington Resources each quarter an administrative services fee for accounting,
bookkeeping and other administrative services relating to the Royalty Interests
and the Underlying Properties. The annual fee for 1997, payable in equal
quarterly installments, was $322,877, and the fee will be adjusted annually,
based upon the change in the Producers' Price Index.

BURLINGTON RESOURCES' CONDITIONAL RIGHT OF REPURCHASE

     Burlington Resources retains in the Trust Agreement the right to repurchase
all (but not less than all) outstanding Units at any time at which 15 percent or
less of the outstanding Units is owned by persons or entities other than
Burlington Resources and its affiliates. Any such repurchase would generally be
at a price equal to the greater of (i) the highest price at which Burlington
Resources or any of its affiliates acquired Units during the 90 days immediately
preceding the Determination Date and (ii) the average closing price of Units on
the New York Stock Exchange for the 30 trading days immediately preceding the
Determination Date. Any such repurchase would be conducted in accordance with
applicable Federal and state securities laws. See "Item 1 -- Description of
Units -- Conditional Right of Repurchase."

POTENTIAL CONFLICTS OF INTEREST

     The interests of Burlington Resources and its subsidiaries and the
interests of the Trust and the Unitholders with respect to the Underlying
Properties could at times be different. As an interest owner in the Underlying
Properties, BROG could have interests that conflict with the interests of the
Trust and Unitholders. For example, such conflicts could be due to a number of
factors including, but not limited to, future budgetary considerations and the
absence of any contractual obligation on the part of BROG to spend for
development of the Underlying Properties, except as noted herein. Such decisions
may have the effect of changing the amount or timing of future distributions to
Unitholders. BROG's interest may also conflict with those of the Trust and
Unitholders in situations involving the sale or abandonment of Underlying
Properties.

                                       48
<PAGE>   52

BROG has the right at any time, pursuant to the terms of the Conveyance, to sell
any of its interest in the Underlying Properties subject to the Royalty
Interests. Such sales may not be in the best interest of the Trust. Except for
amendments to the Gas Purchase Contract, the Gas Gathering Contract or the
Conveyance which must be approved by the vote of the holders of a majority of
all Units then outstanding if such amendment would materially adversely affect
Trust revenues, no mechanism or procedure has been included to resolve potential
conflicts of interest between the Trust and Burlington Resources, BROG, BRTI or
BRGI. To the extent that any matters are brought to a vote of Unitholders where
the interests of Burlington Resources conflict, or potentially conflict, with
the interests of the Trust or Unitholders, Burlington Resources can be expected
to vote in its own self interest. See "Item 2 -- The Royalty Interests -- Sale
and Abandonment of Underlying Properties," "-- Gas Purchase Contract" and
"-- Gas Gathering Contract."
