Offer. The Purchaser will pay all charges and expenses of Jefferies & Company,
Inc., as the Dealer Manager (the "Dealer Manager"), The Bank of New York, as the

     The purpose of the Offer is to acquire, together with Units already owned

liquidated and sold as then required by the terms of the Trust Agreement, among
Meridian Oil Production Inc., Burlington Resources Inc., Mellon Bank (DE)
National Association and NationsBank of Texas, N.A., dated May 1, 1993 (the
"Trust Agreement"), and the eventual distribution to the Unit holders of the
proceeds from the sale of the assets of the Trust. Pursuant to the Trust
Agreement, the affirmative vote by the holders of not less than 66 2/3% of all
of the Units outstanding shall be required to terminate the Trust. See "THE
TENDER OFFER -- 12. Purpose and Structure of the Offer; Plans for the Trust."
 
     Consummation of the Offer is conditioned upon there being validly tendered
and not withdrawn prior to the expiration of the Offer at least the Minimum
Number of Units (the "Minimum Condition"). Purchaser reserves the right (subject
to the applicable rules and regulations of the Securities and Exchange
Commission (the "Commission")), which it currently has no intention of
exercising, to waive or reduce the Minimum Condition and to elect to purchase,
pursuant to the Offer, fewer than the Minimum Number of Units. See
<PAGE>   4
 
"THE TENDER OFFER -- 1. Terms of Offer" and "THE TENDER OFFER -- 14. Certain
Conditions of the Offer."
 
     The Purchaser has filed a Schedule 14D-1 and Schedule 13D with the
Commission in connection with the Offer (the "Purchaser Schedule 14D-1"). The
Purchaser Schedule 14D-1 contains additional information, including exhibits,
relating to the Offer and the Purchaser and may be inspected and copies of such
document may be obtained at the same places and in the same manner as set forth
in "THE TENDER OFFER -- 6. Certain Information Concerning the Trust."
 
     THIS OFFER TO PURCHASE AND THE LETTER OF TRANSMITTAL CONTAIN IMPORTANT
INFORMATION WHICH SHOULD BE READ CAREFULLY BEFORE ANY DECISION IS MADE WITH
RESPECT TO THE OFFER.
 
     TO THE KNOWLEDGE OF THE PURCHASER, AS OF THE DATE OF THIS OFFER TO
PURCHASE, THE TRUSTEE (AS DEFINED BELOW) HAS MADE NO RECOMMENDATION WITH RESPECT
TO THE OFFER.
 
     Holders of record of Units on the record date for any regular quarterly
cash distribution declared by the Trust prior to the transfer to the Purchaser
on the Trust's transfer records of the Units purchased pursuant to the Offer
will be entitled to receive and retain any such regular quarterly cash
distribution. See "THE TENDER OFFER -- 8. Price Range of Units; Cash
Distributions."
 
                                THE TENDER OFFER
 
     1. TERMS OF OFFER. Upon the terms and subject to the conditions of the
Offer (including, if the Offer is extended or amended, the terms and conditions
of any such extension or amendment), the Purchaser will accept and purchase the
Minimum Number of Units that are validly tendered on or prior to the Expiration
Date (as hereinafter defined) and not withdrawn in accordance with "THE TENDER
OFFER -- 3. Withdrawal Rights." The term "Expiration Date" means 12:00 midnight,
New York City time, on Tuesday, February 17, 1998, unless and until the
Purchaser, in its sole discretion, shall have extended the period of time for
which the Offer is open, in which event the term "Expiration Date" shall mean
the latest time and date on which the Offer, as so extended by the Purchaser,
shall expire.
 
     Proration. If more than the Minimum Number of Units is validly tendered in
accordance with the procedures specified in "THE TENDER OFFER -- 2. Procedures
for Tendering Units" and not properly withdrawn in accordance with the
procedures specified in "THE TENDER OFFER -- 3. Withdrawal Rights," the
Purchaser will, upon the terms and subject to the conditions of the Offer, take
into account the number of Units so tendered, accept for payment and pay for the
Minimum Number of Units, pro rata, according to the number of Units validly
tendered by each Unit holder and not properly withdrawn on or prior to the
Expiration Date, with appropriate adjustments to avoid purchases of fractional
Units.
 
     Because of the difficulty of determining the precise number of Units
validly tendered and not withdrawn, if proration of the tendered Units is
required, Purchaser does not expect to be able to announce the final results of
the proration until at least approximately seven business days after the
Expiration Date. The Purchaser does not intend to pay for any Units accepted for
payment pursuant to the Offer until the final proration or other adjustment
results are known.
 
     Satisfaction of Certain Conditions. The Offer is subject to certain
conditions, including, among other things, satisfaction of the Minimum
Condition. See "THE TENDER OFFER -- 14. Certain Conditions of the Offer." If the
Minimum Condition is not satisfied, or if any or all of the other events set
forth in "THE TENDER OFFER -- 14. Certain Conditions of the Offer" shall have
occurred, prior to the Expiration Date, the Purchaser reserves the right (but
shall not be obligated) in its sole discretion to (i) decline to purchase any of
the Units tendered in the Offer, terminate the Offer and return all tendered
Units to the tendering Unit holders, (ii) waive or reduce the Minimum Condition,
or waive or amend any or all other conditions to the Offer to the extent
permitted by applicable law and, subject to complying with applicable rules and
regulations of the Commission, purchase all Units validly tendered, (iii) extend
the Offer and, subject to the right of the
 
                                        2
<PAGE>   5
 
Unit holders to withdraw Units until the Expiration Date, retain the Units that
have been tendered during the period or periods for which the Offer is extended
or (iv) amend the Offer.
 
     Modification of Minimum Number or Consideration. The Purchaser also
reserves the right (but shall not be obligated) to accept for payment more than
the Minimum Number of Units pursuant to the Offer. The Purchaser has no present
intention of exercising such right. If, prior to the Expiration Date, the
Purchaser should decide to increase or decrease the number of Units being sought
or to increase or decrease the consideration being offered in the Offer, subject
to any requirement to extend the period of time during which the Offer is open,
such increase or decrease in the number of Units being sought or such increase
or decrease in the consideration being offered will be applicable to all Unit
holders whose Units are accepted for payment pursuant to the Offer.
 
     Right to Extend or Amend Offer. The Purchaser expressly reserves the right,
in its sole discretion, at any time or from time to time and regardless of
whether or not any of the events set forth in "THE TENDER OFFER -- 14. Certain
Conditions of the Offer" shall have occurred or shall have been determined by
the Purchaser to have occurred, (i) to extend the period of time during which
the Offer is open and thereby delay acceptance for payment of, and the payment
for, all Units validly tendered by giving oral or written notice of such
extension to the Depositary and (ii) to amend the Offer in any respect, by
giving oral or written notice of such extension or amendment to the Depositary.
The rights reserved by the Purchaser in this paragraph are in addition to the
Purchaser's rights to terminate the Offer pursuant to "THE TENDER OFFER -- 14.
Certain Conditions of the Offer." UNDER NO CIRCUMSTANCES WILL INTEREST BE PAID
ON THE PURCHASE PRICE FOR TENDERED UNITS, WHETHER OR NOT THE PURCHASER EXERCISES
ITS RIGHTS TO EXTEND THE OFFER.
 
     Result of Material Modification. If the Purchaser makes a material change
in the terms of the Offer or in the information concerning the Offer or waives a
material condition of the Offer, the Purchaser will disseminate additional
tender offer materials and extend the Offer to the extent required by Rules
14d-4(c) and 14d-6(d) promulgated under the Securities Exchange Act of 1934, as
amended (the "Exchange Act"). The minimum period during which an offer must
remain open following material changes in the terms of the Offer or information
concerning the Offer, other than a change in price or a change in percentage of
securities sought, will depend upon the facts and circumstances, including the
relative materiality of the terms or information changed. With respect to a
change in price or a change in percentage of securities sought, if at the time
notice of such increase or decrease in the number of Units being sought or such
increase or decrease in the consideration being offered is first published, sent
or given to holders of such Units, the Offer is scheduled to expire at any time
earlier than the period ending on the tenth business day from and including the
date that such notice is first so published, sent or given, the Offer will be
extended at least until the expiration of such ten business day period. For
purposes of the Offer, a "business day" means any day other than a Saturday,
Sunday or federal holiday and consists of the time period from 12:01 a.m.
through 12:00 midnight, New York City time.
 
     Announcements. Any extension, amendment or termination will be followed as
promptly as practicable by public announcement thereof, the announcement in the
case of an extension to be issued no later than 9:00 a.m., New York City time,
on the next business day after the previously scheduled Expiration Date in
accordance with the public announcement requirements of Rule 14d-4(c)
promulgated under the Exchange Act. Without limiting the obligation of the
Purchaser under such rule or the manner in which the Purchaser may choose to
make any public announcement, the Purchaser currently intends to make
announcements by issuing a release to the Dow Jones News Service.
 
     Delay of Payments. If the Purchaser extends the Offer, or if the Purchaser
(whether before or after its acceptance for payment of Units) is delayed in its
purchase of or payment for Units or is unable to pay for Units pursuant to the
Offer for any reason, then, without prejudice to the Purchaser's rights under
the Offer, the Depositary may retain tendered Units on behalf of the Purchaser,
and such Units may not be withdrawn except to the extent tendering Unit holders
are entitled to withdrawal rights as described in "THE TENDER OFFER -- 3.
Withdrawal Rights." However, the ability of the Purchaser to delay the payment
for Units that the Purchaser has accepted for payment is limited by Rule
14e-1(c) under the Exchange Act, which requires
 
                                        3
<PAGE>   6
 
that a bidder pay the consideration offered or return the securities deposited
by or on behalf of the holders of securities promptly after the termination or
withdrawal of such bidder's offer.
 
     Request for Unit Holder List. A request has been made to NationsBank of
Texas, N.A. (the "Trustee"), for the use of the Trust's Unit holder list and
security position listings for the purpose of disseminating the Offer to holders
of Units. Once the Trust has provided such list and listings or otherwise
complied with such request, this Offer to Purchase and the Letter of Transmittal
and other relevant materials will be mailed to record holders of Units and will
be furnished to brokers, dealers, commercial banks, trust companies and similar
persons whose names, or the names of whose nominees, appear on the Unit holder
list or, if applicable, who are listed as participants in a clearing agency's
security position listing for subsequent transmittal to beneficial owners of
Units by the Purchaser.
 
     2. PROCEDURES FOR TENDERING UNITS.
 
     Valid Tender of Units. Except as set forth below, for Units to be validly
tendered pursuant to the Offer, a Letter of Transmittal (or facsimile thereof),
properly completed and duly executed, together with any required signature
guarantees, or an Agent's Message in connection with a book-entry delivery of
Units, and any other documents required by the Letter of Transmittal must be
received by the Depositary at one of its addresses set forth on the back cover
page of this Offer to Purchase on or prior to the Expiration Date. In addition,
either (i) certificates for Units representing tendered Units must be received
by the Depositary along with the Letter of Transmittal, or such Units must be
tendered pursuant to the procedure for book-entry transfer described below and a
Book-Entry Confirmation (as defined below) must be received by the Depositary,
in each case prior to the Expiration Date, or (ii) the tendering Unit holder
must comply with the guaranteed delivery procedures set forth below.
 
     Book-Entry Transfer. The Depositary will make a request to establish an
account with respect to the Units at The Depository Trust Company (the
"Book-Entry Transfer Facility") for purposes of the Offer within two business
days after the date of this Offer to Purchase, and any financial institution
which is a participant in the Book-Entry Transfer Facility's system may make
book-entry delivery of Units by causing the Book-Entry Transfer Facility to
transfer such units into the Depositary's account at the Book-Entry Transfer
Facility in accordance with its procedures for transfer. However, although
delivery of Units may be effected through book-entry transfer at the Book-Entry
Transfer Facility, the Letter of Transmittal (or facsimile thereof), with any
required signature guarantees, or an Agent's Message in connection with a
book-entry transfer, and any other required documents must, in any case, be
transmitted to and received by the Depositary at one of its addresses set forth
on the back cover page of this Offer to Purchase prior to the Expiration Date,
or the guaranteed delivery procedures described below must be complied with.
 
     Delivery of documents to the Book-Entry Transfer Facility in accordance
with its procedures does not constitute delivery to the Depositary. None of the
Purchaser, the Purchaser's affiliates or assigns, the Depositary, the Dealer
Manager, the Information Agent or any other person will assume any
responsibility for, or will be under any duty to give notification of, the
failure by the Book-Entry Transfer Facility to forward documents to the
Depositary.
 
     Signature Guarantees. Signatures on all Letters of Transmittal must be
guaranteed by a firm that is a bank, broker, dealer, credit union, savings
association or other entity that is a member in good standing of the Securities
Transfer Agent's Medallion Program ("STAMP"), the Stock Exchange Medallion
Program ("SEMP") or the New York Stock Exchange, Inc. Medallion Signature
Program ("MSP") (each, an "Eligible Institution"), unless the Units tendered
thereby are tendered (i) by a registered holder of Units who has not completed
either the box labeled "Special Delivery Instructions" or the box labeled
"Special Payment Instructions" on the Letter of Transmittal or (ii) for the
account of an Eligible Institution. See Instruction 1 of the Letter of
Transmittal.
 
     If the certificates for Units are registered in the same name of a person
other than the signer of the Letter of Transmittal, or if payment is to be made
to, or certificates for unpurchased Units are to be issued or returned to, a
person other than the registered owner, then the tendered certificates must be
endorsed or accompanied by appropriate transfer powers, in either case signed
exactly as the name or names of the
 
                                        4
<PAGE>   7
 
registered owner or owners appear on the certificates, with the signatures on
the certificates or transfer powers guaranteed by an Eligible Institution as
described above. See Instructions 1 and 5 of the Letter of Transmittal.
 
     Guaranteed Delivery. If a Unit holder desires to tender Units pursuant to
the Offer and certificates for such Units are not immediately available, or time
will not permit all required documents to reach the Depositary on or prior to
the Expiration Date, or the procedures for book-entry transfer cannot be
completed on a timely basis, such Units may nevertheless be tendered if all of
the following guaranteed delivery procedures are duly complied with:
 
          (i) such tender is made by or through an Eligible Institution;
 
          (ii) a properly completed and duly executed Notice of Guaranteed
     Delivery, substantially in the form provided by the Purchaser herewith, is
     received by the Depositary, as provided below, on or prior to the
     Expiration Date; and
 
          (iii) the certificates (or a Book-Entry Confirmation) representing all
     tendered Units, in proper form for transfer, together with a properly
     completed and duly executed Letter of Transmittal (or facsimile thereof),
     with any required signature guarantees (or, in the case of a book-entry
     transfer, an Agent's Message) and any other documents required by the
     Letter of Transmittal, are received by the Depositary within three New York
     Stock Exchange ("NYSE") trading days after the date of the execution of
     such Notice of Guaranteed Delivery.
 
     The Notice of Guaranteed Delivery may be delivered by hand or transmitted
by telegram, facsimile transmission or mailed to the Depositary and must include
a guarantee by an Eligible Institution in the form set forth in such Notice of
Guaranteed Delivery.
 
     THE METHOD OF DELIVERY OF UNITS, THE LETTER OF TRANSMITTAL AND ANY OTHER
REQUIRED DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING UNIT HOLDER. IF
DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY
INSURED, IS RECOMMENDED.
 
     Notwithstanding any other provision hereof, payment for the Units accepted
for payment pursuant to the Offer will in all cases be made only after timely
receipt by the Depositary of certificates for, or of Book-Entry Confirmation
with respect to, such Units, a properly completed and duly executed Letter of
Transmittal (or facsimile thereof), together with any signature guarantees (or,
in the case of a book-entry transfer, an Agent's Message) and any other
documents required by the Letter of Transmittal. Accordingly, payment might not
be made to all tendering Unit holders at the same time and will depend upon when
Units are received into the Depositary's account at the Book-Entry Transfer
Facility.
 
     Backup Federal Tax Withholding. Under the federal income tax laws, the
Depositary will be required to withhold 31% of the amount of any payments made
to certain Unit holders pursuant to the Offer. TO PREVENT BACKUP FEDERAL INCOME
TAX WITHHOLDING WITH RESPECT TO PAYMENT OF THE PURCHASE PRICE OF UNITS SOLD
PURSUANT TO THE OFFER, A TENDERING UNIT HOLDER MUST PROVIDE THE DEPOSITARY WITH
HIS OR HER CORRECT TAXPAYER IDENTIFICATION NUMBER OR CERTIFY THAT HE OR SHE IS
NOT SUBJECT TO BACKUP FEDERAL INCOME TAX WITHHOLDING BY COMPLETING THE
SUBSTITUTE FORM W-9 INCLUDED IN THE LETTER OF TRANSMITTAL.
 
     Appointment as Proxy. By executing a Letter of Transmittal as set forth
above, a tendering Unit holder irrevocably appoints designees of the Purchaser
as his attorneys-in-fact and proxies, in the manner set forth in the Letter of
Transmittal, each with full power of substitution, to the full extent of such
Unit holder's rights with respect to the Units tendered by the Unit holder and
accepted for payment by the Purchaser and with respect to any and all other
Units or other securities, rights or distributions, other than regular cash
distributions declared by the Trust having a record date prior to the date of
transfer to the Purchaser on the Trust's transfer records of the Units tendered
(such Units or other securities, rights or distributions other than such regular
cash distributions being referred to herein as "Distributions"), issued or
issuable in respect of such Units on or after the date of this Offer to
Purchase. All such powers of attorney and proxies shall be considered
irrevocable and coupled with an interest in the tendered Units. This appointment
will be effective when, and only to the extent that, the Purchaser pays for such
Units by depositing the Purchase Price therefor with the Depositary. Upon such
payment, all powers of attorney and proxies given by such Unit holder with
                                        5
<PAGE>   8
 
respect to such Units and any Distributions will, without further action, be
revoked, and no subsequent powers of attorney or proxies may be given by such
Unit holder (and, if given, will not be deemed effective). The designees of the
Purchaser will, with respect to the Units and any Distribution, be empowered to
exercise all voting and other rights of such Unit holder with respect to such
Units and any Distributions as they, in their sole discretion, may deem proper
at any meeting of the Unit holders, or any adjournment or postponement thereof,
or by written consent or otherwise. The Purchaser reserves the right to require
that, in order for Units to be deemed validly tendered, immediately upon the
Purchaser's acceptance for payment of such Units, the Purchaser must be able to
exercise full voting rights with respect to such Units, including voting at any
meeting of Unit holders.
 
     Determination of Validity. All questions as to the form of documents,
validity, eligibility (including time of receipt) and acceptance for payment of
any tender of Units pursuant to any of the procedures described above will be
determined by the Purchaser, in its sole discretion, whose determination will be
final and binding. The Purchaser reserves the absolute right to reject any or
all tenders of any Units determined by it not to be in proper form or the
acceptance of or payment for which may, in the opinion of the Purchaser's
counsel, be unlawful. The Purchaser also reserves the absolute right to waive
any of the conditions of the Offer or any defect or irregularity in any tender
of Units of any particular Unit holder.
 
     The Purchaser's interpretation of the terms and conditions of the Offer
(including the Letter of Transmittal and the instructions thereto) will be final
and binding. No tender will be deemed to have been validly made until all
defects and irregularities with respect to such tender have been cured or
waived. None of the Purchaser, the Purchaser's affiliates or assigns, the
Depositary, the Dealer Manager, the Information Agent or any other person will
be under any duty to give notification of any defects or irregularities in
tenders or incur any liability for failure to give such notification.
 
     A tender of Units pursuant to any one of the procedures described above
will constitute the tendering Unit holder's acceptance of the terms and
conditions of the Offer, as well as the tendering Unit holder's representation
and warranty that (i) such Unit holder has full power and authority to tender,
sell, assign and transfer such Units, (ii) the tender of the tendered Units
complies with Rule 14e-4 under the Exchange Act and (iii) when the same are
accepted for payment by the Purchaser, the Purchaser will acquire good,
marketable and unencumbered title thereto, free and clear of all liens,
restrictions, charges and encumbrances and will not be subject to any adverse
claim. The Purchaser's acceptance for payment of Units tendered pursuant to the
Offer will constitute a binding agreement between the tendering Unit holder and
the Purchaser upon the terms and subject to the conditions to the Offer.
 
     3. WITHDRAWAL RIGHTS. Except as otherwise provided in this Section 3,
tenders of Units made pursuant to the Offer are irrevocable, provided that Units
tendered pursuant to the Offer may be withdrawn at any time prior to the
Expiration Date and, unless theretofore accepted for payment by the Purchaser as
provided herein, may also be withdrawn at any time after March 20, 1998, or at
such later time as may apply if the Offer is extended.
 
     If, for any reason whatsoever, acceptance for payment of Units tendered
pursuant to the Offer is delayed, or the Purchaser is unable to accept for
payment or pay for Units tendered pursuant to the Offer, then, without prejudice
to the Purchaser's rights set forth herein, the Depositary may, nevertheless, on
behalf of the Purchaser, retain tendered Units, and such Units may not be
withdrawn except to the extent that the tendering Unit holder is entitled to and
duly exercises withdrawal rights as described in this Section 3. Any such delay
will be by an extension of the Offer to the extent required by law.
 
     For a withdrawal to be effective, a written, telegraphic or facsimile
transmission notice of withdrawal must be timely received by the Depositary at
one of its addresses specified on the back cover of this Offer to Purchase. Any
such notice of withdrawal must specify the name of the person who tendered the
Units to be withdrawn, the number of Units to be withdrawn, and (if certificates
for Units have been tendered) the name of the registered holder of the Units as
set forth in the certificate for the Unit, if different from the name of the
person who tendered such Units. If certificates for Units to be withdrawn have
been delivered or otherwise identified to the Depositary, then, prior to the
release of such certificates, the serial numbers shown on such certificates must
be submitted to the Depositary and, unless such Units have been tendered by an
Eligible
                                        6
<PAGE>   9
 
Institution, the signatures on the notice of withdrawal must be guaranteed by an
Eligible Institution. If Units have been tendered pursuant to the procedure for
book-entry transfer as set forth in "THE TENDER OFFER -- 2. Procedures for
Tendering Units," any notice of withdrawal must also specify the name and number
of the account at the Book-Entry Transfer Facility to be credited with the
withdrawn Units and otherwise comply with the Book-Entry Transfer Facility's
procedures.
 
     Withdrawals of tenders of Units may not be rescinded and any Units properly
withdrawn will thereafter be deemed not validly tendered for purposes of the
Offer. However, withdrawn Units may be retendered by again following one of the
procedures described in "THE TENDER OFFER -- 2. Procedures for Tendering Units"
at any time prior to the Expiration Date.
 
     All questions as to the form and validity (including time of receipt) of
notices of withdrawal will be determined by the Purchaser, in its sole
discretion, whose determination will be final and binding. None of the
Purchaser, the Purchaser's affiliates or assigns, the Depositary, the Dealer
Manager, the Information Agent or any other person will be under any duty to
give notification of any defects or irregularities in any notice of withdrawal
or incur any liability for failure to give such notification.
 
     4. ACCEPTANCE FOR PAYMENT AND PAYMENT FOR UNITS. Upon the terms and subject
to the conditions of the Offer (including, if the Offer is extended or amended,
the terms and conditions of any such extension or amendment), the Purchaser will
purchase, by accepting for payment, and will pay for the Minimum Number of Units
validly tendered prior to the Expiration Date (and not properly withdrawn in
accordance with "THE TENDER OFFER -- 3. Withdrawal Rights") as promptly as
practicable after the Expiration Date.
 
     UNDER NO CIRCUMSTANCE WILL INTEREST ON THE PURCHASE PRICE BE PAID,
REGARDLESS OF ANY EXTENSION OF THE OFFER OR ANY DELAY IN MAKING SUCH PAYMENT.
 
     The Purchaser expressly reserves the right, in its sole discretion, to
delay acceptance for payment of, or, subject to the requirements of Rule
14e-1(c) referred to in "THE TENDER OFFER -- 1. Terms of the Offer," payment
for, Units in order to comply in whole or in part with any applicable law or
condition. See "THE TENDER OFFER -- 14. Certain Conditions of the Offer." In all
cases, payment for Units purchased pursuant to the Offer will be made only after
timely receipt by the Depositary of (i) certificates for such Units or timely
confirmation (a "Book-Entry Confirmation") of a book-entry transfer of such
Units into the Depositary's account at the Book-Entry Transfer Facility pursuant
to the procedures set forth in "THE TENDER OFFER -- 2. Procedures for Tendering
Units," (ii) the Letter of Transmittal (or facsimile thereof), properly
completed and duly executed, with any required signature guarantees, or an
Agent's Message (as defined below) in connection with a book-entry transfer, and
(iii) any other documents required by the Letter of Transmittal.
 
     The term "Agent's Message" means a message, transmitted by the Book-Entry
Transfer Facility to, and received by, the Depositary and forming a part of a
Book-Entry Confirmation, which states that the Book-Entry Transfer Facility has
received an express acknowledgment from the participant in the Book-Entry
Transfer Facility tendering the Units which are the subject of such Book-Entry
Confirmation that such participant has received and agrees to be bound by the
terms of the Letter of Transmittal and that the Purchaser may enforce such
agreement against such participant.
 
     For purposes of the Offer, the Purchaser will be deemed to have accepted
for payment (and thereby purchased) Units validly tendered and not withdrawn as,
if and when the Purchaser gives oral or written notice to the Depositary of the
Purchaser's acceptance of such Units for payment pursuant to the Offer. Upon the
terms and subject to the conditions of the Offer, payment for Units purchased
pursuant to the Offer will be made by deposit of the Purchase Price therefor
with the Depositary, which will act as agent for tendering Unit holders for the
purpose of receiving payment from the Purchaser and transmitting payment to
tendering Unit holders. Under no circumstances will interest on the Purchase
Price be paid by the Purchaser by reason of any delay in making such payment.
 
     If any tendered Units are not purchased pursuant to the Offer for any
reason, or if certificates are submitted representing more Units than are
tendered, certificates for tendered Units not purchased or tendered will be
returned, without expense to the tendering Unit holder (or, in the case of Units
tendered by
                                        7
<PAGE>   10
 
book-entry transfer into the Depositary's account at the Book-Entry Transfer
Facility pursuant to the procedures set forth in "THE TENDER OFFER -- 2.
Procedures for Tendering Units," such Units will be credited to the account
maintained at the Book-Entry Transfer Facility), as promptly as practicable
after the expiration, termination or withdrawal of the Offer.
 
     If, on or prior to the Expiration Date, the Purchaser shall increase the
consideration offered to Unit holders pursuant to the Offer, such increased
consideration shall be paid to all Unit holders whose Units have previously been
accepted for payment pursuant to the Offer.
 
     5. CERTAIN FEDERAL INCOME TAX CONSEQUENCES. The following summary of
federal income tax consequences is based upon laws, regulations, interpretive
rulings and judicial decisions in effect on the date hereof, all of which are
subject to change (possibly with retroactive effect). This summary does not
discuss all aspects of federal income taxation that may be relevant to a
particular taxpayer in light of its personal investment circumstances or to
certain types of taxpayers subject to special treatment under the federal income
tax laws (such as life insurance companies, banks, tax-exempt organizations,
nonresident aliens and foreign corporations). This summary also does not discuss
any aspect of state, local or foreign taxation. Accordingly, each Unit holder is
urged to consult with its own tax advisor as to the tax ramifications of
tendering Units pursuant to the Offer.
 
     Tendering Unit Holders. Each tendering Unit holder will be treated, for
federal income tax purposes, as having disposed of an undivided interest in each
of the assets of the Trust. As a result, each tendering Unit holder will
recognize gain or loss, for federal income tax purposes, measured by the
difference between the amount realized on the sale and the Unit holder's tax
basis in the Unit sold. A Unit holder's tax basis in its Units will generally
include its allocable share of the debts of the Trust, if any, at the time that
the Unit holder acquired its Units, and such tax basis must be reduced, but not
below zero, by any depletion deductions that the Unit holder has been allowed. A
Unit holder's amount realized will generally include an allocable share of the
debts of the Trust, if any, at the time the Units are sold pursuant to the
Offer. The character of the gain or loss as ordinary income or loss or as
capital gain or loss (and, if capital gain or loss, as long-term or short-term)
will be determined by reference to the Royalty Interests (as defined in "THE
TENDER OFFER -- 6. Certain Information Concerning the Trust"), rather than by
reference to the Units (with the result, inter alia, that the depletion
recapture rules will generally require a Unit holder to recharacterize, as
ordinary income, any capital gain recognized in connection with the sale of
Units, but not in excess of the depletion deductions previously allowed to the
Unit holder that were applied to reduce tax basis). A tendering Unit holder who
has taken a Section 29 tax credit will not have to recapture as ordinary income
any amount previously taken as a credit. While net capital gains are taxed, in
the case of corporate taxpayers, at the same rates that apply to ordinary
income, such gains are taxed, in the case of individual taxpayers, at a maximum
rate of (i) 28% if the relevant holding period is more than 12 months but no
more than 18 months and (ii) 20% if the relevant holding period is more than 18
months. Capital losses may be used, for federal income tax purposes, to offset
only capital gains and may not be used to offset ordinary income (subject to a
$3,000 exemption in the case of individual taxpayers).
 
     The Trust will allocate its income, gain, loss, deduction and credit for
1998 between a tendering Unit holder and the Purchaser based on the number of
monthly record dates of regular cash distributions by the Trust that each such
person held the Unit during the year.
 
     Non-Tendering Unit Holders. The Trust will continue to be classified as a
grantor trust subsequent to the consummation of the Offer and will not be
required to close its taxable year, change its method of accounting or otherwise
be adversely affected as a result of the Offer. Upon the successful consummation
of the Offer, the Purchaser intends to call a meeting of the Unit holders within
one year from the date of this Offer to Purchase for the purpose of voting on
the termination of the Trust. See "THE TENDER OFFER -- 12. Purpose and Structure
of the Offer; Plans for the Trust." In the event of dissolution, each Unit
holder will directly own and control its interests in the Royalty Interests. The
tax treatment of directly holding such Royalty Interests will be substantially
similar to the tax treatment of indirectly owning such properties through the
Trust, except that the rules of administrative convenience imposed by the Trust,
such as allocation of the Section 29 credit on a quarterly basis, will no longer
be applicable.

     THE FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE IS INCLUDED FOR GENERAL
INFORMATION ONLY. UNIT HOLDERS ARE URGED TO CONSULT THEIR TAX ADVISORS WITH
RESPECT TO THE TAX CONSEQUENCES TO THEM OF THE OFFER, INCLUDING THE EFFECTS OF
FEDERAL, STATE AND LOCAL TAX CONSEQUENCES THEREOF.
 
     6. CERTAIN INFORMATION CONCERNING THE TRUST. According to the Trust's
Annual Report on Form 10-K for the fiscal year ended December 31, 1996 (the
"Trust 10-K"), the Trust was created under the laws of the State of Delaware.
According to the Trust 10-Q, the Trust maintains its principal offices at the

pursuant to the terms of the Trust Agreement to acquire and hold certain net
profits interests (the "Royalty Interests") in Meridian Oil Production Inc.'s
interest in the Fruitland coal formation underlying the Northeast Blanco Unit
(the "Underlying Properties"). The Purchaser believes that the name of Meridian
Oil Production Inc. has been changed to Burlington Resources Oil & Gas Company
("BROG").
 
     The Trust is subject to the information and reporting requirements of the
Exchange Act and in accordance therewith files reports and other information

     Loan Agreement. The Purchaser has entered into an Advancing Term Credit
Agreement dated January 15, 1998 (the "Loan Agreement") with the Lender. The
following is a summary of the Loan Agreement, a copy of which is attached to the
Purchaser Schedule 14D-1 as Exhibit (b) and is incorporated by reference herein.
All references to and summaries of the Loan Agreement herein are qualified in
their entirety by reference to the Loan Agreement. The Loan Agreement provides
that the Lender will provide up to $25 million in financing (the "Loan") to the
Purchaser, subject to satisfaction of certain conditions discussed below. The
material terms of the Loan Agreement are as follows:
 
     Pursuant to the Loan Agreement, the Lender will lend to the Purchaser an
amount equal to the lesser of $25 million or 50% of the purchase price of the
Units purchased by Purchaser, up to a certain specified purchase price. The
facility may only be used as bridge financing in support of the Offer.
 
     The Loan Agreement provides that the Loan will be secured by a first lien
security interest in substantially all of the assets of Purchaser, including,
but not limited to, the Units acquired by the Purchaser, Purchaser's rights and
interests under the Trust and all of the dividends, disbursements,
distributions, products and proceeds thereof.
 
     The Loan Agreement provides that the interest rate for the Loan will be, at
the option of the Purchaser, LIBOR plus 2% per annum, based on 30, 60 and 90 day
options, or the Bank One base rate (the "Base Rate"). Draws can be made through
January 1, 1999. Interest on the loan will be due and payable quarterly for all
Loan amounts accruing interest at the Base Rate or at the maturity of individual
LIBOR tranches.
 
     The Loan Agreement states that the Loan will have a maturity date of
January 2, 1999, provided that the maturity date will be automatically extended
to July 1, 1999, if (i) on January 2, 1999, no event of default or event which,
with the giving of notice or passage of time or both, would become an event of
default, has occurred and is continuing, (ii) on or before January 2, 1999 (a)
the Purchaser has paid to the Lender an additional fee in the amount of 0.25% of
the amount of the loan commitment then in effect, (b) the owners of
 
                                       16
<PAGE>   19
 
66.67% of the Units have voted to liquidate the Trust and (c) the Trustee has
taken certain actions described in Section 9.03(b) of the Trust Agreement,
including the making of certain notices required in the Trust Agreement and
retaining an investment banking firm on behalf of the Trust to help value the
Trust's assets, evaluate offers to purchase Trust assets, seek buyers for the
Trust's assets and render certain fairness opinions. At maturity, the
outstanding principal balance on the Loan will be due and payable. Mandatory
prepayments will be required if the Loan balance exceeds the lesser of (i) a
specified borrowing base or (ii) 70% of the per Unit price at which Units are
trading, multiplied by the number of Units owned by the Purchaser.
 
     The funding of the Loan is conditioned upon the following items: (i) the
Trust has good and defensible title to its assets, free and clear of all liens,
encumbrances and adverse claims; (ii) receipt and acceptance by the Lender of a
satisfactory funding request; (iii) satisfactory evidence that all of the
Purchaser's representations and warranties are true, that it is not in default
of any of its covenants and that no event of default has occurred under any of
the loan documents; (iv) the contemporaneous acquisition by the Purchaser of the
Units on which the Borrowing base was calculated; and (v) that no material
adverse change shall have occurred since the date of the Loan Agreement in the
condition, financial or otherwise, of the Purchaser or Trust.
 
     Pursuant to the Loan Agreement, the Lender received a facility fee paid at
closing of $125,000, and will receive a fee payable on each funding equal to
$1,406.25. Purchaser also paid a $10,000 engineering and underwriting fee. In
addition, at closing, the Purchaser paid the Lender a $52,500 fee and a $15,000
retainer for legal fees to the Lender's counsel.
 
     Pursuant to the Loan Agreement, the Purchaser is subject to certain
periodic reporting requirements to the Lender and must disclose other
information as required by the Lender from time to time. The Purchaser also is
subject to certain representations and warranties, covenants and events of
default, including covenants (i) that, if the Trustee is not actively pursuing
liquidation of the Trust by September 1, 1998 to the satisfaction of the Lender,
within 45 days thereafter the Purchaser shall have completed a tax credit
monetization transaction, 100% of the net proceeds of which shall be paid into a
cash collateral account established with the Lender, (ii) that general and
administrative expenses of the Purchaser will not exceed $100,000 per year,
(iii) that the Purchaser will comply with applicable laws and regulations
(including applicable environmental laws), pay taxes, accounts payable and other
uncontested obligations of the Purchaser, including certain fees, maintain its
existence and good standing, maintain its material tangible property and
maintain customary insurance, and (iv) that require average year-to-date
distributions from the Trust to the Purchaser with respect to each Unit owned by
the Purchaser to be equal to at least $0.15 per Unit per calendar quarter.
Negative covenants in the Loan Agreement restrict the Purchaser's ability, with
certain limited exceptions, to incur debt, make loans or other investments,
create liens or security interests on its assets, materially change the nature
of its business, sell assets, declare or pay dividends, allow the termination of
any insurance policy, change its corporate structure, permit any change in the
legal or beneficial ownership of the Purchaser or enter into transactions with
any of its affiliates other than arm's-length transactions. Purchaser has also
agreed to indemnify and to reimburse the Lender for certain expenses.
 
     It is anticipated that the indebtedness incurred pursuant to the Loan
Agreement will be repaid from funds generated by the Trust and distributed to
the Unit holders and by the liquidation of the Trust. See "THE TENDER
OFFER -- 12.  Purpose and Structure of the Offer; Plans for the Trust." To the
extent that the equity financing and the Loan Agreement do not provide
sufficient funds to consummate the Offer, the Purchaser will attempt to arrange
for additional financing or equity sources to satisfy such obligations. The
Purchaser has not made any arrangements for such additional financing or equity,
and there can be no assurance that such financing or equity will be available
or, if available, on terms favorable to the Purchaser.
 
     Because the Loan has a maturity date of January 2, 1999 and is subject to
extension to July 1, 1999 if the Trust has not terminated and its assets have
not been distributed in a sufficient amount to satisfy all amounts due
thereunder by such date, the Purchaser will be required to seek an additional
extension of the Loan from the Lender. In the event that the Lender does not
extend the Loan, the Purchaser will attempt to arrange for additional financing
or equity sources to repay the Loan in full by such maturity date. If the
Purchaser is unable to obtain such additional financing, however, the Purchaser
may be required to liquidate some or all of
 
                                       17
<PAGE>   20
 
the Units it has acquired either pursuant to the Offer or prior to the
commencement of the Offer to satisfy its payment obligations under the Loan.
 
     The Lender is an affiliate of Banc One Capital Partners VIII, Ltd., which
is the general partner of BOCP. BOCP is one of the Acquirors.
 
     11. BACKGROUND OF THE OFFER; PAST CONTACTS, TRANSACTIONS OR NEGOTIATIONS
WITH THE TRUST. During the week of October 13, 1997, Scott W. Smith, a
consultant to O'Sullivan Oil and a member and manager of Smith Funding, spoke
with Ron E. Hooper, Vice President of the Trustee, pursuant to a telephone
conversation. During such conversation, Mr. Smith, on behalf of C. N.
O'Sullivan, President of O'Sullivan Oil, requested an opportunity to review the
ownership ledger of the Trust. Mr. Hooper requested that Mr. Smith provide
written notice of such request.
 
     On October 20, 1997, Mr. Smith sent the following letter by overnight
courier to the Trustee:
 
     October 20, 1997                                            Federal Express
 
     Nationsbank of Texas, N.A., Trustee
     Burlington Resources Coal Seam Gas Royalty Trust
     910 Main Street, Suite 1700
     Dallas, Texas 75202
 
     Attention: Mr. Ron Hooper
 
     Re: Inspection of Books
 
     Gentlemen:
 
     Pursuant to Article 12.01 of the Trust Agreement of the Burlington
     Resources Coal Seam Gas Royalty Trust dated May 1, 1993, by and between
     Meridian Oil Production, Inc., Burlington Resources, Inc., Mellon Bank
     National Association and Nationsbank of Texas, N.A., Chris N. O'Sullivan,
     as the owner of 20,000 units of said trust is hereby requesting the
     opportunity to review the ownership ledger of the trust at your earliest
     convenience.
 
     Mr. O'Sullivan owns these units in Account No. 32004087 at the firm of
     Morgan Keegan & Company, Inc. Should you have any questions concerning his
     position, please contact Mr. William Vaseliades at (713) 840-3628.
 
     We are looking forward to hearing from you as soon as possible to schedule
     a mutually agreeable appointment.
 
     Very truly yours,
 
     Scott W. Smith
 
     SWS/ncy
 
     On or about October 21, 1997, Mr. Smith contacted Mr. Hooper by telephone
regarding the request to review the ownership ledger of the Trust. Mr. Hooper
responded that the Trustee would confer with its counsel concerning the
Trustee's response to the request.
 
     During the week of October 27, 1997, Mr. Smith contacted the Trustee by
telephone. During this telephone conversation with Mr. Hooper, a meeting date of
November 11, 1997, was set for Mr. Smith to review the ownership ledger
concerning the Units.
 
                                       18
<PAGE>   21
 
     On November 11, 1997, at the offices of the Trustee, Mr. Smith reviewed a
Unit ownership ledger, dated as of September 2, 1997.
 
     On November 24, 1997, Mr. Smith contacted the Trustee by telephone. Mr.
Smith requested information concerning the calculation of the tax credit
allocation in connection with the 1997 fourth quarter distribution, which was
announced on November 1, 1997. Donald Yuchs, a representative of the Trustee, in
response to the request of Mr. Smith, faxed Mr. Smith several sheets regarding
the cash and tax credit allocation for the fourth quarter distribution.
 
     Except as described in this Offer to Purchase, there have been no contacts,
transactions or negotiations between any of the Acquirors or the Acquiror
Affiliates, or, to the best of any Acquiror's knowledge, any of their respective
affiliates or subsidiaries or any of the persons listed on Schedule I, on the
one hand, and the Trust or any of its affiliates, on the other hand, concerning
a merger, consolidation or acquisition, a tender offer or other acquisition of
securities, an election of directors, or sale or other transfer of a material
amount of the Trust's assets.
 
     12. PURPOSE AND STRUCTURE OF THE OFFER; PLANS FOR THE TRUST. The purpose of
the Offer is to acquire a significant number of Units as the first step in the
ultimate termination of the Trust. The Purchaser is conducting the Offer and
pursuing the termination of the Trust with the intention of making a profit;
consequently, the interests of the Purchaser and the other Acquirors may be
adverse to the interests of other Unit holders.
 
     Subsequent to the successful consummation of the Offer, the Purchaser
currently intends to call a meeting of the Unit holders within one year of the
date of this Offer to Purchase for the purpose of voting on the termination of
the Trust. If a meeting of the Unit holders is held concerning the termination
of the Trust, the Purchaser intends to vote any Units it holds at the time of
such meeting in favor of terminating the Trust.
 
     The information in the following paragraphs of this Section 12 has been
taken or derived from the Trust Agreement, which was filed as Exhibit 3.1 to the
Registration Statement on Form S-3 (Registration No. 33-61164), as amended,
filed by Burlington Resources Inc. with the Commission on its own behalf and as
sponsor of the Trust. More comprehensive information concerning meetings of Unit
holders and the termination of the Trust is included in the Trust Agreement, and
the information set forth below is qualified in its entirety by reference to the
Trust Agreement.
 
     According to the terms of the Trust Agreement, the Trust may terminate
prior to January 1, 2003, only upon the affirmative vote in favor of termination
of the Trust by the holders of at least 66 2/3% of the outstanding Units. A
meeting of the Unit holders may be called by Unit holders owning of record not
less than 10% of the then outstanding Units. After the successful conclusion of
the Offer, the Purchaser intends to call a special meeting of the Unit holders
for the purpose of voting to terminate the Trust pursuant to a notice
distributed to all of the Unit holders of record. The notice of such meeting
must be distributed at least 20, but not more than 60, days prior to the date of
the meeting. At such meeting, if the holders of at least 66 2/3% of the Units
vote to terminate the Trust, the Trustee will commence the liquidation process,
and the Trust will still continue until all of the affairs of the Trust are
liquidated and wound up.
 
     Within five business days of the date the Unit holders vote to terminate
the Trust (the "Termination Date"), the Trustee must (i) provide BROG,
Burlington Resources Inc. and Mellon Bank (DE) National Association (the
"Delaware Trustee") or its successor with written notice of the termination of
the Trust and (ii) engage an investment banking firm (the "Advisor") to assist
the Trustee in selling the remaining Royalty Interests then owned by the Trust
(the "Remaining Royalty Interests").
 
     BROG may, but is not obligated to, make a written cash offer to purchase
the Remaining Royalty Interests, which offer must be delivered to the Trustee
within 60 days following the Termination Date (the "Option Period Termination
Date"). If BROG does make an offer to purchase the Remaining Royalty Interests,
the Trustee must decide, based on the recommendation of the Advisor, whether to
accept the offer. The Trustee must provide written notice to BROG of the
decision by the later of (i) the Option Period Termination Date or (ii) the
tenth business day after the date the Trustee receives BROG's offer. The
Trustee's notice must state that the Trustee (i) accepts the offer (which
acceptance is conditional on the
                                       19
<PAGE>   22
 
receipt of an opinion of the Advisor of the fairness of BROG's offer to the Unit
holders from a financial point of view) or (ii) defers action on the offer. If
the Trustee accepts BROG's offer, BROG and the Trustee must use their best
efforts to close the purchase within 30 days of BROG's receipt of notice of
acceptance.
 
     If the Trustee defers action on BROG's offer, the Trustee must use its best
efforts, with the Advisor's assistance, to obtain other cash offers for the
Remaining Royalty Interests. The Trustee must notify BROG of the highest offer,
if any, received by the Trust within 120 days following the Termination Date. If
the highest offer is more than 105% of BROG's original offer, or if BROG did not
make an offer, BROG may, but is not obligated to, purchase all of the Remaining
Royalty Interests for a cash purchase price equal to 105% of the highest offer.
If the highest offer is equal to or less than 105% of BROG's original offer,
BROG may, but is not obligated to, purchase all of the Remaining Royalty
Interests for a cash purchase price equal to the highest offer. BROG must
provide written notice of its election to purchase the Remaining Royalty
Interests within five business days of BROG receipt of notice of the highest
offer. BROG and the Trustee must use their best efforts to close the purchase
within 30 days of BROG's receipt of notice of the highest offer.
 
     If no other acceptable cash offers are received for the Remaining Royalty
Interests, the Trustee may request that BROG submit another offer. If BROG makes
an offer, and the Trustee accepts it, the acceptance will be conditional upon
receipt of an opinion of the Advisor of the fairness of the offer to the Unit
holders. BROG and the Trustee must use their best efforts to close the purchase
within 30 days of BROG's receipt of notice of acceptance of the offer.
 
     If any assets or property of the Trust estate have not been sold, or no
definitive agreement for their sale has been entered into, within one year after
the Termination Date, the Trustee will cause the property to be sold at public
auction to the highest bidder (which may be BROG or any of its affiliates).
Notice of such auction must be mailed to each Unit holder at least 30 days prior
to the sale.
 
     Although the Purchaser has not made any determination to do so, the
Purchaser or one of its affiliates may seek to purchase assets of the Trust. If
the Purchaser or one of its affiliates do not buy the assets of the Trust in the
event of the proposed termination of the Trust, there can be no assurance that a
buyer could be found for the assets of the Trust. Furthermore, there can be no
assurance as to whether or when any such transaction might be proposed by the
Purchaser or its affiliates or as to the purchase price which might be offered
by the Purchaser or its affiliates or by any third party in any such
transaction.
 
     The Purchaser and its affiliates also reserve the right, following
termination of the Offer, to purchase additional Units, either in open market or
privately negotiated transactions, in one or more additional tender offers or
otherwise, or to sell all or any portion of the Units owned by them. Any such
sales or purchases would depend upon current market prices for the Units,
prevailing industry and general economic and market conditions, the business,
financial condition and results of operations of the Trust and other relevant
factors, and would be on such terms and at such prices as the Purchaser or its
affiliates may then determine.
 
     The Trust Agreement provides that, under certain circumstances, the Trustee
and the Delaware Trustee may be removed by a majority vote of the Unit holders.
The Purchaser has no present plans to vote its Units for the removal of either
the Trustee or the Delaware Trustee.
 
     Currently, the Purchaser has no intention to materially change the
distributions of the Trust, except as set forth in this Offer to Purchase.
 
     The Purchaser is not, pursuant to the Offer, requesting votes by Unit
holders in favor of terminating the Trust or on any other matters. Such a
request, if any, will occur pursuant to a proxy statement prepared in accordance
with applicable law, distributed to Unit holders after the successful
consummation of the Offer, and in the event the Purchaser shall deliver to the
Unit holders a notice of meeting in accordance with the Trust Agreement and
applicable law.
 
     13. EFFECT OF THE OFFER ON THE MARKET FOR UNITS; NYSE LISTING AND EXCHANGE
ACT REGISTRATION; MARGIN REGULATIONS. The purchase of Units pursuant to the
Offer will reduce the number of Units that might otherwise trade publicly and
the number of holders of Units and could adversely affect the liquidity and
market value of the remaining Units held by the public. The purchase of Units
pursuant to the Offer can also be expected to reduce the number of holders of
Units.
 
                                       20
<PAGE>   23
 
     In addition, if the Trust is dissolved, as described in "THE TENDER
OFFER -- 12. Purpose and Structure of the Offer; Plans for the Trust," the Units
may be delisted by the NYSE, and the registration of the Units under the
Exchange Act would be terminated.
 
     Stock Exchange Listing. According to the NYSE's published guidelines, the
NYSE would consider delisting the Units if, among other things, the number of
record holders of at least 100 Units should fall below 1,200 (the number of
beneficial holders of Units held in nominee form through an NYSE member being
considered for such purpose), the number of publicly held Units (exclusive of
holdings of officers, directors, their immediate families and other concentrated
holdings of 10% or more ("NYSE Excluded Holdings")) should fall below 600,000,
or the aggregate market value of such Units should fall below $5,000,000.
 
     Depending on the number of Units purchased pursuant to the Offer, the Units
may no longer meet the requirements of the NYSE for continued listing and may,
therefore, be delisted from such exchange. If, as a result of the purchase of
Units pursuant to the Offer or otherwise, the Units no longer meet the
requirements of the NYSE for continued listing and/or trading and such trading
of the Units were discontinued, the market for such Units could be adversely
affected.
 
     In the event of the delisting of the Units by the NYSE (which the Purchaser
intends to cause the Trust to seek following the Offer if the continued listing
criteria of the NYSE are no longer satisfied), it is possible that the Units
would continue to trade on another securities exchange or in the
over-the-counter market and that price quotations would be reported by such
exchange, by the National Association of Securities Dealers, Inc. (the "NASD")
through the NASD Automated Quotation System ("Nasdaq") or by other sources. The
extent of the public market for Units and the availability of such quotations
would, however, depend upon such factors as the number of Unit holders remaining
at such time, the interest in maintaining a market in such Units on the part of
securities firms, the possible termination of registration under the Exchange
Act as described below and other factors.
 
     Exchange Act Registration. The Units are currently registered under the
Exchange Act. The purchase of the Units pursuant to the Offer may result in the
Units becoming eligible for deregistration under the Exchange Act. Registration
of the Units under the Exchange Act may be terminated upon application of the
Trust to the Commission if the Units are not listed on a national securities
exchange and there are fewer than 300 record holders of the Units. Termination
of registration of the Units under the Exchange Act would substantially reduce
the information required to be furnished by the Trust to Unit holders and to the
Commission and would make certain provisions of the Exchange Act, such as the
short-swing profit recovery provisions of Section 16(b) of the Exchange Act and
the requirements of furnishing a proxy statement in connection with Unit
holders' meeting pursuant to Section 14(a) of the Exchange Act, no longer
applicable to the Trust. If the Units are no longer registered under the
Exchange Act, the requirements of Rule 13e-3 under the Exchange Act with respect
to "going private" transactions would no longer be applicable to the Trust.
Furthermore, the ability of "affiliates" of the Trust and persons holding
"restricted securities" of the Trust to dispose of such securities pursuant to
Rule 144 promulgated under the Securities Act of 1933, as amended, may be
impaired or eliminated. In addition, if registration of the Units under the
Exchange Act were terminated, the Units would no longer be eligible for listing
or Nasdaq reporting.
 
     It is the present intention of the Purchaser to seek to cause the Trust to
make such an application for termination of registration of the Units as soon as
possible following the Offer if the requirements for termination of registration
are met.
 
     Margin Regulations. The Units are presently "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System (the
"Federal Reserve Board"), which has the effect, among other things, of allowing
brokers to extend credit on the collateral of such Units for the purpose of
buying, carrying or trading in securities ("Purpose Loans"). Depending upon
factors such as the number of record holders of the Units and the number and
market value of publicly held Units, following the purchase of Units pursuant to
the Offer, the Units may no longer constitute margin securities for purposes of
the Federal Reserve Board's margin regulations and, therefore, could no longer
be used as collateral for Purpose Loans made by brokers. In addition, if
registration of the Units under the Exchange Act were terminated, the Units
would no longer constitute margin securities.

     14. CERTAIN CONDITIONS OF THE OFFER. Notwithstanding any other provisions
of the Offer and in addition to (and not in limitation of) the Purchaser's
rights to extend and amend the Offer at any time in its sole discretion, the
Purchaser shall not be required to accept for payment, purchase or pay for,
subject to Rule 14e-1(c) under the Exchange Act and any other applicable rules
and regulations of the Commission, any Units not theretofore accepted for
payment or paid for and may terminate or amend the Offer as to such Units unless
(i) the Minimum Condition is satisfied, (ii) the satisfaction of the conditions
to the funding of the Loan, as described in "THE TENDER OFFER -- 10. Financing
of the Offer," and (iii) approvals required by law to be obtained prior to the
consummation of the Offer under any antitrust or competition laws relating to
the purchase of the Units pursuant to the Offer shall have been obtained.
Furthermore, notwithstanding any other term of the Offer, the Purchaser shall
not be required to accept for payment or to pay for any Units not theretofore
accepted for payment or paid for, and may terminate or amend the Offer if at any
time prior to the expiration of the Offer, any of the following conditions exist
or shall occur and remain in effect:
 
          (a) there shall be threatened, instituted or pending any action or
     proceeding by or before any court or governmental, administrative or
     regulatory agency or authority or any other person, domestic or foreign,
     challenging the making of the Offer or the acquisition by the Purchaser of
     any Units, or otherwise directly or indirectly relating to the Offer or, in
     the sole judgment of the Purchaser, otherwise adversely affecting the
     Trust, the Purchaser, any of the other Acquirors or any of their respective
     subsidiaries or affiliates; or
 
          (b) any change shall have occurred or be threatened in the properties,
     financial condition, operations, results of operations or prospects of the
     Trust or the Royalty Interests that, in the sole judgment of the Purchaser,
     is or may be materially adverse to the Trust or the Royalty Interests, or
     the Purchaser shall have become aware of any facts that, in the sole
     judgment of the Purchaser, have or may have material adverse significance
     with respect to the value of the Trust or the Royalty Interests or the
     value of the Units to the Purchaser; or
 
          (c) a tender or exchange offer for some portion or all of the Units
     shall have been publicly proposed to be made or shall have been made by
     another person, or it shall have been publicly disclosed or the Purchaser
     shall have learned that (i) any person or "group" (as defined in Section
     13(d)(3) of the Exchange Act) shall have acquired or proposed to acquire
     more than 5% of the outstanding Units, other than acquisitions for bona
     fide arbitrage purposes and other than acquisitions by persons or groups
     who have publicly disclosed such ownership on or prior to the date of this
     Offer to Purchase or (ii) any such person or group who has publicly
     disclosed any such ownership of more than 5% of the Units prior to such
     date shall have acquired or proposed to acquire additional Units
     constituting more than 1% of the outstanding Units or shall have been
     granted any option or right to acquire more than 1% of the outstanding
     Units; or
 
          (d) there shall have been any action taken, or any statute, rule,
     regulation or order proposed, promulgated, enacted, entered or deemed
     applicable to the Offer, by any domestic or foreign government or
     governmental authority or by any court, domestic or foreign, that, in the
     sole judgment of the Purchaser, might (i) make the acceptance for payment
     of or payment for some or all of the Units illegal or otherwise restrict or
     prohibit consummation of the Offer, or impose material obligations upon the
     Purchaser as a result of any such acceptance or payment, (ii) result in a
     delay in the ability of the Purchaser, or render the purchaser unable, to
     accept for payment or pay for some or all of the Units, (iii) require the
     Purchaser or the Trust or any of their respective affiliates to hold
     separate or to divest itself of all or any portion of the business, assets
     or property of any of them or any Units or impose any limitation on the
     ability of any of them to conduct their business and own such assets,
     properties and Units, (iv) impose material limitations on the ability of
     the Purchaser to acquire, hold or exercise effectively all rights of
     ownership of the Units, including the right to vote any Units purchased by
     it on all matters properly presented to the Unit holders or (v) otherwise
     adversely affect the Purchaser, any of the other Acquirors, the Trust or
     the Units; or
 
                                       22
<PAGE>   25
 
          (e) there shall have been proposed or adopted by the Trustee or any
     Unit holder any amendment to the Trust Agreement, any proposal to terminate
     the Trust or any proposal for the sale or transfer by the Trust of all or
     any portion of the Royalty Interests; or
 
          (f) there shall occurred (i) any general suspension of trading, or
     limitation on prices for, securities on any national securities exchange or
     in the over-the-counter market in the United States, (ii) a declaration of
     a banking moratorium or any suspension of payments in respect of banks in
     the United States, (iii) the commencement of war, armed hostilities or
     other international or national calamity directly or indirectly involving
     the United States, (iv) any limitation (whether or not mandatory) by any
     United States governmental authority or agency on the extension of credit

     or (vi) in the case of any of the situations described in the clauses (i)
     through (iv) inclusive, existing at the date of the commencement of the

which, in the sole judgment of the Purchaser, in any such case, and regardless
of the circumstances (including any action or inaction by the Purchaser, the
other Acquirors or any of their affiliates) giving rise to any such condition,
makes it inadvisable to proceed with the Offer or with acceptance for payment or
payment for Units.
 
     The foregoing conditions are for the sole benefit of the Purchaser, the
other Acquirors and their respective affiliates and may be asserted by the
Purchaser, in whole or in part, at any time and from time to time in the sole
judgment of the Purchaser. The failure by the Purchaser at any time to exercise
its rights under any of the foregoing conditions shall not be deemed a waiver of
any such rights and each such right shall be deemed an ongoing right which may
be asserted at any time or from time to time. Any determination by the Purchaser
concerning the events described in this Section shall be final and binding on
all parties.
 
     15. APPRAISAL RIGHTS. Holders of Units do not have appraisal rights in
connection with the Offer.
 
     16. CERTAIN TRANSACTIONS. Effective as of September 1, 1997, O'Sullivan Oil
and Scully Oil & Gas Company acquired a 0.0572% non-operated working/0.05033%
net revenue interest in the Underlying Properties. The president and sole
shareholder of Scully Oil & Gas Company is Christopher P. Scully. Each of
Christopher P. Scully and O'Sullivan Oil are Acquirors.
 
     17. CERTAIN LEGAL MATTERS.
 
     General. Except as set forth in this Offer to Purchase, including but not
limited to this Section 17, based upon an examination of publicly available
information filed by the Trust with the Commission and other publicly available
information with respect to the Trust, the Purchaser is not aware of any license
or any other regulatory permit that appears to be material to the business of
the Trust, that might be adversely affected by the Purchaser's acquisition of
the Units as contemplated herein or, except as disclosed below, of any filing,
approval or other action by or with any state, federal or foreign governmental,
administrative or regulatory agency that would be required prior to the
acquisition of Units pursuant to the Offer as contemplated herein. Should any
such approval or other action be required, the Purchaser currently contemplates
that such approval or other action will be sought. While the Purchaser does not
currently intend to delay the acceptance for payment of Units tendered pursuant
to the Offer pending the outcome of any such matter, there can be no assurance
that any such approval or other action, if needed, would be obtained or would be
obtained without substantial conditions or that failure to obtain any such
approval or other action might not result in consequences adverse to the
properties and assets of the Trust or that certain of the Trust's properties and
assets might not have to be disposed of in the event that such approvals were
not obtained or such other actions were not taken in order to obtain any such
approval or other action. If certain types of adverse action are taken with
respect to the matters discussed below, the Purchaser could decline to accept
for payment or pay for any Units tendered. See "THE TENDER OFFER -- 14. Certain
Conditions of the Offer" for certain conditions to the Offer, including
conditions with respect to litigation and governmental action.
 
                                       23
<PAGE>   26
 
     State Takeover Statutes. Based upon its knowledge of the assets of the
Trust and upon publicly available information with respect to the Trust, the
Purchaser does not believe that any state takeover statutes or regulations are
applicable to the Offer. In the event that it is asserted that one or more state
takeover statutes or regulations is applicable to the Offer, and an appropriate
court does not determine that it is inapplicable or invalid as applied to the
Offer, the Purchaser might be required to file certain information with, or
receive approvals from, the relevant state authorities, and the Purchaser might
be unable to purchase or pay for Units tendered pursuant to the Offer or might
be delayed in continuing or consummating the Offer. In such case, the Purchaser
may not be obligated to accept Units for payment. See "THE TENDER
OFFER -- 14. Certain Conditions of the Offer."
 
     Antitrust. Under the Hart-Scott-Rodino Antitrust Improvements Act of 1976,
as amended (the "HSR Act"), certain acquisition transactions may not be
consummated unless certain information has been furnished to the Antitrust
Division of the Department of Justice (the "Antitrust Division") and the Federal
Trade Commission (the "FTC") and certain waiting period requirements have been
satisfied. The Purchaser believes that the acquisition of Units pursuant to the
Offer is not subject to the HSR Act or such requirements. However, if the HSR
Act is applicable to the purchase of Units pursuant to the Offer, the Purchaser
intends to take all action necessary to comply with the HSR Act, which could
result in a delay in the consummation of the Offer pending the satisfaction of
the waiting period requirements of the HSR Act.
 
     The Antitrust Division and the FTC frequently scrutinize the legality under
the antitrust laws of transactions such as the acquisition of Units by the
Purchaser pursuant to the Offer. At any time before or after the consummation of
the transaction, the Antitrust Division or the FTC could take such action under
the antitrust laws as it deems necessary or desirable in the public interest,
including seeking to enjoin the transaction or seeking divestiture of the Units
so acquired or divestiture of substantial assets of the Purchaser or the Trust.
 
     The Purchaser believes that the acquisition of the Units pursuant to the
Offer would not violate the antitrust laws. However, there can be no assurance
that a challenge to the Offer on antitrust grounds will not be made, or if such
a challenge is made, what the result will be. See "THE TENDER OFFER -- 14.
Certain Conditions of the Offer" for certain conditions to the Offer, including
conditions with respect to litigation and certain governmental actions.
 
     18. FEES AND OTHER EXPENSES. The Purchaser has retained Jefferies &
Company, Inc. in connection with the Offer to provide advice and assistance to
Purchaser with respect to defining objectives, and to act as the Dealer Manager
in connection with the Offer. The terms of such engagement are set forth in a
Dealer Manager Agreement (herein so called) dated January 20, 1998. Jefferies &
Company, Inc. was not asked to, and did not, provide any report, opinion or
appraisal in connection with the Offer.
 
     Pursuant to the Dealer Manager Agreement, a fee of $75,000 became payable
to the Dealer Manager upon the Dealer Manager's engagement thereunder. The
Dealer Manager is entitled to an additional $0.02 per Unit tendered and accepted
by Purchaser pursuant to the Offer. In the event that the Trust is terminated
and the Trust assets are liquidated following completion of the Offer, the
Dealer Manager also will be entitled to an additional of $0.04 for each Unit (i)
purchased by the Purchaser pursuant to the Offer or (ii) acquired by the
Purchaser in an open market transaction after January 7, 1998, solely through
brokerage services provided by the Dealer Manager. The Purchaser has also agreed
to reimburse the Dealer Manager for its out-of-pocket expenses and to indemnify
the Dealer Manager against certain liabilities and expenses, including certain
liabilities under the federal securities laws. In the ordinary course of its
business, the Dealer Manager may actively trade the Units for its own account
and for the account of customers and, accordingly, may at any time hold a long
or short position in such securities.
 
     The Purchaser also has retained Morrow & Co., Inc. to act as the
Information Agent and The Bank of New York to act as the Depositary in
connection with the Offer. The Information Agent may contact holders of Units by
mail, telephone, telex, telecopy, telegraph and personal interview and may
request banks, brokers, dealers and other nominee Unit holders to forward
materials relating to the Offer to beneficial holders. Each of the Information
Agent and the Depositary will receive reasonable and customary compensation for
its services,
 
                                       24
<PAGE>   27
 
will be reimbursed for certain reasonable out-of-pocket expenses and will be
indemnified against certain liabilities and expenses in connection therewith.
 
     Brokers, dealers, commercial banks and trust companies will, upon request
only, be reimbursed by the Purchaser for customary mailing and handling expenses
incurred by them in forwarding material to their customers. Except as set forth
above, the Purchaser will not pay any fees or commissions to any broker, dealer
or other person (other than to the Dealer Manager and to the Information Agent)
for soliciting tenders of Units pursuant to the Offer.
 
     19. MISCELLANEOUS. The Offer is not being made to (nor will tenders be
accepted from or on behalf of) holders of Units residing in any jurisdiction in
which the making of the Offer or the acceptance thereof would not be in
compliance with the securities, blue sky or other laws of such jurisdiction. The
Purchaser is not aware of any jurisdiction in which the making of the Offer or
the acceptance thereof would not be in compliance with the laws of such
jurisdiction. To the extent the Purchaser becomes aware of any state law that
would limit the class of offerees in the Offer, the Purchaser may, in its
discretion, take such action as it may deem necessary to make the Offer in any
jurisdiction and extend the Offer to holders of Units in such jurisdiction.
 
     In any jurisdiction where the securities, blue sky or other laws require
the Offer to be made by a licensed broker or dealer, the Offer will be deemed to
be made on behalf of the Purchaser by one or more registered brokers or dealers
that are licensed under the laws of such jurisdiction.
 
     The Acquirors have filed with the Commission a Tender Offer Statement on
the Purchaser Schedule 14D-1, together with exhibits thereto, furnishing certain
additional information with respect to the Offer, and may file amendments
thereto from time to time. The Schedules and any amendments thereto, including
exhibits, may be examined and copies may be obtained from the offices of the
Commission in the manner set forth in "THE TENDER OFFER -- 6. Certain
Information Concerning the Trust" (except that such information will not be
available at the regional offices of the Commission).
 
     NO PERSON HAS BEEN AUTHORIZED TO GIVE ANY INFORMATION OR MAKE ANY
REPRESENTATION ON BEHALF OF THE PURCHASER NOT CONTAINED IN THIS OFFER TO
PURCHASE OR IN THE LETTER OF TRANSMITTAL, AND, IF GIVEN OR MADE, ANY SUCH
INFORMATION OR REPRESENTATION MUST NOT BE RELIED ON AS HAVING BEEN AUTHORIZED.
NEITHER THE DELIVERY OF THE OFFER TO PURCHASE NOR ANY PURCHASE PURSUANT TO THE
OFFER SHALL, UNDER ANY CIRCUMSTANCES, CREATE ANY IMPLICATION THAT THERE HAS BEEN
NO CHANGE IN THE AFFAIRS OF THE PURCHASER OR THE TRUST SINCE THE DATE AS OF
WHICH INFORMATION IS FURNISHED OR THE DATE OF THIS OFFER TO PURCHASE.

Ladies and Gentlemen:
 
          The undersigned hereby tenders to San Juan Partners, L.L.C., a Texas
limited liability company (the "Purchaser"), the above-described Units of
Beneficial Interest (the "Units") of Burlington Resources Coal Seam Gas Royalty
Trust, a Delaware business trust (the "Trust"), pursuant to the Purchaser's
offer to purchase 5,446,860 Units at a price of $8.25 per unit, net to the
seller in cash, without interest thereon (the "Purchase Price"), upon the terms
and subject to the conditions set forth in the Purchaser's Offer to Purchase
dated January 20, 1998, as amended from time to time (the "Offer to Purchase"),
receipt of which is hereby acknowledged, and this Letter of Transmittal (which,
together with any amendments or supplements to such documents, constitute the
"Offer").
 
          Subject to, and effective upon, the acceptance for payment of, and
payment for, the Units tendered herewith in accordance with the terms and
subject to the conditions of the Offer (including, if the Offer is extended or
amended, the terms and conditions of any such extension or amendment), the
undersigned hereby sells, assigns and transfers to, or upon the order of, the
Purchaser all right, title and interest in and to all the Units that are being
tendered hereby (and any and all other Units, other securities, rights or
distributions issued or issuable in respect to such Units on or after the date
of the Offer to Purchase, other than regular cash distributions declared by the
Trust having a record date prior to the date of transfer to the Purchaser or its
nominees or assignees on the Trust's transfer records of the Units tendered
herewith as provided in the Offer to Purchase (such Units or other securities,
rights or distributions other than such regular cash distributions being
referred to herein as "Distributions")) and irrevocably constitutes and appoints
the Depositary the true and lawful agent and attorney-in-fact of the undersigned
with respect to such Units (and any Distributions), with full power of
substitution (such power of attorney being deemed to be an irrevocable power
coupled with an interest), to: (a) deliver certificates for such Units (and any
Distributions) or transfer ownership of such Units (and any Distributions) on
the account books maintained by the Book-Entry Transfer Facility together, in
either such case, with all accompanying evidences of transfer and authenticity,
to, or upon the order of, the Purchaser, (b) present such Units (and any
Distributions) for transfer on the Trust transfer records and (c) receive all
benefits and otherwise exercise all rights of beneficial ownership of such Units
(and any Distributions), all in accordance with the terms of the Offer.
 
          The undersigned hereby irrevocably appoints C. N. O'Sullivan and Scott
W. Smith, and each of them, and any other designees of the Purchaser, the
attorneys-in-fact and proxies of the undersigned, each with full power of
substitution, to exercise all voting and other rights of the undersigned,
including the execution of any written consent, in such manner as each such
attorney-in-fact and proxy or his substitute shall, in his sole discretion, deem
proper with respect to all of the Units tendered hereby (and any Distributions)
which have been accepted for payment by the Purchaser prior to the time of any
vote or other action at any meeting of Unit holders of the Trust. This power of
attorney and proxy are irrevocable, and are granted in consideration of, and are
effective upon, the acceptance for payment of such Units in accordance with the
terms of the Offer. Such acceptance for payment shall, without further action,
revoke all prior powers of attorney and proxies appointed by the undersigned at
any time with respect to such Units (and any Distributions) and no subsequent
powers of attorney or proxies will be appointed by the undersigned (and if given
or executed, will not be deemed effective). The Purchaser expressly reserves the
right to require that, in order for Units (and any Distributions) to be validly
tendered, immediately upon the acceptance for payment of such Units (and any
Distributions), the Purchaser must be able to exercise full voting rights with
respect to such Units (and any Distributions).
 
          The undersigned hereby represents and warrants that the undersigned
has full power and authority to tender, sell, assign and transfer the Units
tendered hereby (and any Distributions), the tender of the tendered Units
complies with Rule 14e-4 under the Securities Exchange Act of 1934, as amended,
and, when the same are accepted for payment by the Purchaser, the Purchaser will
acquire good, marketable and unencumbered title thereto, free and clear of all
liens, restrictions, charges and encumbrances, and the same will not be subject
to any adverse claim. The undersigned will, upon request, execute and deliver
any additional documents deemed by the Depositary or the Purchaser to be
necessary or desirable to complete or confirm the sale, assignment and transfer
of the Units tendered hereby (and any Distributions).

          All authority conferred or agreed to be conferred pursuant to this
Letter of Transmittal shall be binding upon the personal representatives,
successors, assigns, heirs, executors, administrators, trustees in bankruptcy
and legal representatives of the undersigned and shall not be affected by, and
shall survive, the death or incapacity of the undersigned. Except as stated in
the Offer to Purchase, this tender is irrevocable.
 
          The undersigned understands that tenders of Units pursuant to any one
of the procedures described in "THE TENDER OFFER -- 2. Procedures for Tendering
Units" of the Offer to Purchase and in the instructions hereto will constitute
an agreement between the undersigned and the Purchaser upon the terms and
subject to the conditions of the Offer. Without limiting the foregoing, if the
Offer Price is amended in accordance with the Offer, the price to be paid to the
undersigned will be the amended price notwithstanding the fact that a different
price is stated in this Letter of Transmittal. The undersigned recognizes that,
under certain circumstances set forth in the Offer to Purchase, the Purchaser
may not be required to accept for payment any of the Units tendered hereby.
 
          The undersigned acknowledges that, subject to the applicable rules of
the Securities and Exchange Commission (the "Commission"), the Purchaser
expressly reserves the right, in its sole discretion, at any time or from time
to time and regardless of whether or not any of the events set forth in "THE
TENDER OFFER -- 14. Certain Conditions of the Offer" of the Offer to Purchase
shall have occurred or shall have been determined by the Purchaser to have
occurred, (i) to extend the period of time during which the Offer is open and
thereby delay acceptance for payment of, and the payment for, all Units validly
tendered by giving oral or written notice of such extension to the Depositary
and (ii) to amend the Offer in any respect, by giving oral or written notice of
such extension or amendment to the Depositary. The undersigned acknowledges that
these rights reserved by the Purchaser are in addition to the Purchaser's rights
to terminate the Offer pursuant to "THE TENDER OFFER -- 14. Certain Conditions
of the Offer" of the Offer to Purchase. UNDER NO CIRCUMSTANCES WILL INTEREST BE
PAID ON THE PURCHASE PRICE FOR TENDERED UNITS, WHETHER OR NOT THE PURCHASER
EXERCISES ITS RIGHTS TO EXTEND THE OFFER.
 
          The undersigned also acknowledges that, subject to the applicable
rules of the Commission, if the Minimum Condition (as defined in the Offer to
Purchase) is not satisfied, or if any or all of the other events set forth in
"THE TENDER OFFER -- 14. Certain Conditions of the Offer" of the Offer to
Purchase shall have occurred prior to the Expiration Date, the Purchaser
reserves the right (but shall not be obligated) in its sole discretion to (i)
decline to purchase any of the Units tendered in the Offer, terminate the Offer
and return all tendered Units to the tendering Unit holders, (ii) waive or
reduce the Minimum Condition, or waive or amend any or all other conditions to
the Offer to the extent permitted by applicable law and, subject to complying
with applicable rules and regulations of the Commission, purchase all Units
validly tendered, (iii) extend the Offer and, subject to the right of the Unit
holders to withdraw Units until the Expiration Date, retain the Units that have
been tendered during the period or periods for which the Offer is extended or
(iv) amend the Offer.
 
          Unless otherwise indicated herein under "Special Payment
Instructions," please issue the check for the Purchase Price of any Units
purchased, and return any certificates for Units not tendered or not purchased,
in the name(s) of the undersigned (and, in the case of Units tendered by

Facility). Similarly, unless otherwise indicated under "Special Delivery
Instructions," please mail the check for the Purchase Price for any Units
purchased, and return any certificates for Units not tendered or not purchased

Delivery Instructions and the Special Payment Instructions are completed, please

certificates for Units not tendered or not purchased, in the name(s) of, and
mail said check and any certificates to, the person(s) so indicated. Unless
otherwise indicated under "Special Payment Instructions," please credit any
Units tendered herewith by book-entry transfer that are not accepted for payment
by crediting the account at the Book-Entry Transfer Facility. The undersigned
recognizes that the Purchaser has no obligation, pursuant to the Special Payment
Instructions, to transfer any Units from the name of the registered holder(s)
thereof if the Purchaser does not accept for payment any of the Units so
tendered.

             FORMING PART OF THE TERMS AND CONDITIONS OF THE OFFER
 
     1. GUARANTEE OF SIGNATURES. Except as otherwise provided below, signatures

exactly as the name or names of the registered owner or owners appear on the

     2. DELIVERY OF LETTER OF TRANSMITTAL AND CERTIFICATES; GUARANTEED DELIVERY
PROCEDURES. This Letter of Transmittal is to be completed by Unit holders either

of the Offer to Purchase. Certificates for all physically delivered Units, or a
confirmation of a book-entry transfer into the Depositary's account at the

Agent's Message in the case of a book-entry transfer, must be received by the
Depositary at its address set forth on the front page of this Letter of
Transmittal on or prior to the Expiration Date.
 
     Unit holders whose certificates for Units are not immediately available or
who cannot deliver their certificates and all other required documents to the
Depositary or complete the procedures for book-entry transfer prior to the
Expiration Date must tender their Units pursuant to the guaranteed delivery
procedures set forth in "THE TENDER OFFER -- 2. Procedures for Tendering Units"
of the Offer to Purchase. Pursuant to such procedures: (a) such tender must be
made by or through an Eligible Institution; (b) a properly completed and duly
executed Notice of Guaranteed Delivery, substantially in the form provided by
the Purchaser, must be received by the Depositary on or prior to the Expiration
Date; and (c) the certificates for all tendered Units, in proper form for
tender, or Book-Entry Confirmation of a transfer into the Depositary's account
at the Book-Entry Transfer Facility of all Units delivered electronically, as
well as a properly completed and duly executed Letter of Transmittal (or
facsimile thereof), and any other documents required by this Letter of
Transmittal, or an Agent's Message in the case of a book-entry transfer, must be
received by the Depositary within three New York Stock Exchange ("NYSE") trading
days after the date of execution of such Notice of Guaranteed Delivery, all as

     THE METHOD OF DELIVERY OF UNITS, THIS LETTER OF TRANSMITTAL AND ALL OTHER
REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH THE BOOK-ENTRY TRANSFER FACILITY,
IS AT THE OPTION AND RISK OF THE TENDERING UNIT HOLDER. UNITS WILL BE DEEMED
DELIVERED ONLY WHEN ACTUALLY RECEIVED BY THE DEPOSITARY (INCLUDING, IN THE CASE
OF A BOOK-ENTRY TRANSFER, BY BOOK-ENTRY CONFIRMATION). IF DELIVERY IS BY MAIL,
REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY INSURED, IS RECOMMENDED.
IN ALL CASES, AMPLE TIME SHOULD BE ALLOWED FOR SUCH DOCUMENTS TO REACH THE
DEPOSITARY.
 
     No alternative, conditional or contingent tenders will be accepted, and no
fractional Units will be purchased. All tendering Unit holders, by execution of
this Letter of Transmittal (or facsimile thereof), waive any right to receive
any notice of the acceptance of their Units for payment.

<PAGE>   9
 
     3. INADEQUATE SPACE. If the space provided herein is inadequate, the
certificate numbers and/or the number of Units should be listed on a separate
signed schedule attached hereto.
 
     4. PARTIAL TENDERS (NOT APPLICABLE TO UNIT HOLDERS WHO TENDER BY BOOK-ENTRY
TRANSFER). If fewer than all the Units evidenced by any certificate submitted
are to be tendered, fill in the number of Units that are to be tendered in the
box entitled "Number of Units Tendered." In such a case, new certificate(s) for
the remainder of the Units that were evidenced by the old certificate(s) will be
sent to the person(s) signing this Letter of Transmittal, unless otherwise
provided in the appropriate box on this Letter of Transmittal, as soon as
practicable after the expiration of the Offer. All Units represented by
certificates delivered to the Depositary will be deemed to have been tendered
unless otherwise indicated.
 
     5. SIGNATURES ON LETTERS OF TRANSMITTAL; STOCK POWERS AND ENDORSEMENTS. If
this Letter of Transmittal is signed by the registered holder(s) of the Units
tendered hereby, the signature(s) must correspond with the name(s) as written on
the face of the certificate(s) without alteration, enlargement or any change
whatsoever.
 
     If any of the Units tendered hereby are owned of record by two or more
persons, all such owners must sign this Letter of Transmittal.
 
     If any tendered Units are registered in different names on several
certificates, it will be necessary to complete, sign and submit as many separate
Letters of Transmittal as there are different registrations of certificates.
 
     If this Letter of Transmittal or any certificates or stock powers are
signed by a trustee, executor, administrator, guardian, attorney-in-fact,
officer of a corporation or other person acting in a fiduciary or representative
capacity, such person should so indicate when signing, and proper evidence
satisfactory to the Purchaser of such authority so to act must be submitted.
 
     When this Letter of Transmittal is signed by the registered holder(s) of
Units listed and transmitted hereby, no endorsements of certificates or separate
stock powers are required unless payment is to be made to, or certificates for
Units not tendered or accepted for payment are to be issued to, a person other
than the registered holder(s). Signatures on such certificates or stock powers
must be guaranteed by an Eligible Institution.
 
     If this Letter of Transmittal is signed by a person other than the
registered holder(s) of certificates listed, the certificates must be endorsed
or accompanied by appropriate stock powers, in either case signed exactly as the
name or names of the registered owner or owners appear on the certificates.
Signatures on such certificates or stock powers must be guaranteed by an
Eligible Institution.
 
     6. STOCK TRANSFER TAXES. Except as set forth in this Instruction 6, the
Purchaser will pay any stock transfer taxes with respect to the transfer and
sale of Units to it, or to its order, pursuant to the Offer. If, however,
payment of the Purchase Price is to be made to, or if certificates for Units not
tendered or accepted for payment are to be registered in the name of, any person
other than the registered holder(s), or if tendered certificates are registered
in the name of any person other than the person(s) signing this Letter of
Transmittal, the amount of any stock transfer taxes (whether imposed on the
registered holder(s) or such other person or otherwise) payable on account of
the transfer to such person will be deducted from the Purchase Price unless
satisfactory evidence of the payment of such taxes, or exemption therefrom, is
submitted.
 
     EXCEPT AS PROVIDED IN THIS INSTRUCTION 6, IT WILL NOT BE NECESSARY FOR
TRANSFER TAX STAMPS TO BE AFFIXED TO THE CERTIFICATES LISTED IN THIS LETTER OF
TRANSMITTAL.
 
     7. SPECIAL PAYMENT AND DELIVERY INSTRUCTION. If a check for the Purchase
Price of any Units purchased is to be issued, or any Units not tendered or not
purchased are to be returned, in the name of a person other than the person(s)
signing this Letter of Transmittal, or if the check or any certificates for
Units not tendered or not purchased are to be mailed to someone other than the
person(s) signing this Letter of Transmittal or to the person(s) signing this
Letter of Transmittal at an address other than that shown above, the appropriate
boxes on this Letter of Transmittal should be completed. Unit holders tendering
Units by book-entry transfer may request that Units not purchased be credited to
such account at the Book-Entry Transfer Facility as such
                                        9
<PAGE>   10
 
Unit holder may designate under "Special Payment Instructions." If no such
instructions are given, any such Units not purchased will be returned by
crediting the account at the Book-Entry Transfer Facility designated above.
 
     8. REQUEST FOR ASSISTANCE OR ADDITIONAL COPIES. Requests for assistance may
be directed to the Information Agent or the Dealer Manager at their respective
addresses set forth below. Additional copies of the Offer to Purchase, this
Letter of Transmittal and the Notice of Guaranteed Delivery may be obtained from
the Information Agent or the Dealer Manager at their respective addresses set
forth below or from your broker, dealer, commercial bank, trust company or other
nominee.
 
     9. WAIVER OF CONDITIONS. Subject to the applicable rules and regulations of
the Commission, the conditions of the Offer may be waived by the Purchaser, in
whole or in part, at any time and from time to time in the Purchaser's sole
discretion, in the case of any Units tendered.
 
     10. SUBSTITUTE FORM W-9. Under U.S. federal income tax law, a Unit holder
whose tendered Units are accepted for payment is required to provide the
Depositary with such Unit holder's correct taxpayer identification number
("TIN") on Substitute Form W-9 above. If such Unit holder is an individual, the
TIN is such Unit holder's social security number. If the Depositary is not
provided with the correct TIN, the Internal Revenue Service may subject the Unit
holder or other payee to a $50 penalty. In addition, payments that are made to
such Unit holder or other payee with respect to Units purchased pursuant to the
Offer may be subject to 31% backup withholding.
 
     Certain Unit holders (including, among others, all corporations and certain
foreign individuals) are not subject to these backup withholding and reporting
requirements. In order for a foreign individual to qualify as an exempt
recipient, that Unit holder must submit a statement, signed under penalty of
perjury, attesting to that individual's exempt status. Such statements may be
obtained from the Depositary. All exempt recipients (including foreign persons
wishing to qualify as exempt recipients) should see the enclosed Guidelines for
Certification of Taxpayer Identification Number on Substitute Form W-9 for
additional instructions.
 
     If backup withholding applies, the Depositary is required to withhold 31%
of any such payments made to the Unit holder or other payee. Backup withholding
is not an additional tax. Rather, the tax liability of persons subject to backup
withholding will be reduced by the amount of tax withheld. If withholding
results in an overpayment of taxes, a refund may be obtained from the Internal
Revenue Service.
 
     The box in Part III of the Substitute Form W-9 may be checked if the
tendering Unit holder or other payee has not been issued a TIN and has applied
for a TIN or intends to apply for a TIN in the near future. If the box in Part
III is checked, the Unit holder or other payee must also complete the
Certificate of Awaiting Taxpayer Identification Number below in order to avoid
backup withholding. Notwithstanding that the box in Part III is checked and the
Certificate of Awaiting Taxpayer Identification Number is completed, the
Depositary will withhold 31% on all payments made prior to the time a properly
certified TIN is provided to the Depositary. However, such amounts will be
refunded to such Unit holder if a TIN is provided to the Depositary within 60
days.
 
     The Unit holder is required to give the Depositary the TIN (e.g., social
security number or employer identification number) of the record holder of the
Units or of the last transferee appearing on the transfers attached to, or
endorsed on, the Units. If the Units are in more than one name or are not in the
name of the actual holder, consult the enclosed "Guidelines for certification of
Taxpayer Identification Number on Substitute Form W-9" for additional guidance
on which number to report.
 
     IMPORTANT: THIS LETTER OF TRANSMITTAL OR A FACSIMILE COPY THEREOF (TOGETHER
WITH CERTIFICATES FOR, OR A BOOK-ENTRY CONFIRMATION WITH RESPECT TO, TENDERED
UNITS WITH ANY REQUIRED SIGNATURE GUARANTEES AND ALL OTHER REQUIRED DOCUMENTS)
MUST BE RECEIVED BY THE DEPOSITARY, OR THE NOTICE OF GUARANTEED DELIVERY MUST BE
RECEIVED BY THE DEPOSITARY, PRIOR TO THE EXPIRATION DATE.

discretion, at any time or from time to time and regardless of whether or not
any of the events set forth in "THE TENDER OFFER -- 14. Certain Conditions of
the Offer" of the Offer to Purchase shall have occurred or shall have been
determined by the Purchaser to have occurred, (i) to extend the period of time
during which the Offer is open and thereby delay acceptance for payment of, and
the payment for, all Units validly tendered by giving oral or written notice of
such extension to the Depositary and (ii) to amend the Offer in any respect, by
giving oral or written notice of such extension or amendment to the Depositary.
These rights reserved by the Purchaser are in addition to the Purchaser's rights

     Subject to the applicable rules of the Commission, if the Minimum Condition
(as defined in the Offer to Purchase) is not satisfied, or if any or all of the
other events set forth in "THE TENDER OFFER -- 14. Certain Conditions of the
Offer" of the Offer to Purchase shall have occurred prior to the Expiration
Date, the Purchaser reserves the right (but shall not be obligated) in its sole
discretion to (i) decline to purchase any of the Units tendered in the Offer,
terminate the Offer and return all tendered Units to the tendering Unit holders,

conditions to the Offer to the extent permitted by applicable law and, subject
to complying with applicable rules and regulations of the Commission, purchase
all Units validly tendered, (iii) extend the Offer and, subject to the right of
the Unit holders to withdraw Units until the Expiration Date, retain the Units
that have been tendered during the period or periods for which the Offer is

maintained at the Book-Entry Transfer Facility (as described in the Offer to

Transmittal and the Offer to Purchase.
 
     If holders of Units wish to tender, but it is impracticable for them to
forward their certificates for Units or other required documents on or prior to
the Expiration Date or to comply with the book-entry transfer procedures on a
timely basis, a tender may be effected by following the guaranteed delivery
