                                      AND
                               OFFER TO PURCHASE
                    FOR CASH ANY AND ALL OF THE OUTSTANDING
                 8 1/4% CONVERTIBLE SUBORDINATED NOTES DUE 2002
                      OF REMINGTON OIL AND GAS CORPORATION
 
SUBJECT TO THE TERMS AND CONDITIONS SET FORTH IN THIS CHANGE IN CONTROL NOTICE
AND OFFER TO PURCHASE, THE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT 5:00 P.M.,
NEW YORK CITY TIME, ON FEBRUARY 19, 1999, UNLESS THE OFFER IS EXTENDED IN
ACCORDANCE WITH THE INDENTURE (AS DEFINED HEREIN) (SUCH TIME AND DATE OR THE
LATEST EXTENSION THEREOF, IF EXTENDED, THE "EXPIRATION DATE"). NOTES TENDERED IN
THE OFFER MAY BE WITHDRAWN AT ANY TIME PRIOR TO THE EXPIRATION DATE.
 
BECAUSE A CHANGE OF CONTROL AS DEFINED IN THE INDENTURE OCCURRED, THE COMPANY IS
REQUIRED TO MAKE THIS OFFER TO PURCHASE. IF NO CHANGE OF CONTROL HAD OCCURRED,
THE COMPANY WOULD NOT OFFER TO PURCHASE THE NOTES. THE COMPANY DOES NOT BELIEVE
THAT PURCHASING THE NOTES AT THIS TIME IS THE BEST USE OF THE COMPANY'S CAPITAL
OR CREDIT RESOURCES. NO ACTION BY THE NOTE HOLDER IS REQUIRED UNLESS THE NOTE
HOLDER WISHES TO TENDER NOTES UNDER THIS OFFER TO PURCHASE. NOTES NOT TENDERED
WILL REMAIN OBLIGATIONS OF THE COMPANY UNDER THE TERMS AND CONDITIONS OF THE
INDENTURE.
 
     Remington Oil and Gas Corporation (the "Company") hereby offers (the
"Offer") to purchase for the Purchase Price (as defined below) in cash, upon the
terms and subject to the conditions set forth in this Change in Control Notice
and Offer to Purchase (this "Offer to Purchase") and in the accompanying Letter
of Transmittal (the "Letter of Transmittal"), any and all of the outstanding
8 1/4% Convertible Subordinated Notes due 2002 of the Company (the "Notes"). The
"Purchase Price" is 100% of the principal amount of the Notes, plus accrued
interest (in the amount of $19.48 per $1,000 principal amount of Notes) through
February 25, 1999 (the "Payment Date"), or a later date if the Expiration Date
is extended as set forth in "The Offer -- Expiration Date; Extensions;
Amendments; Termination." The Company will not extend the Expiration Date unless
required by law. Unless the Company fails to pay the Purchase Price, any Notes
properly tendered pursuant to the Offer and accepted for payment will cease to
accrue interest after the Payment Date. ANY NOTES NOT SURRENDERED IN THE OFFER
(OR SURRENDERED AND WITHDRAWN PRIOR TO THE EXPIRATION DATE) WILL REMAIN
OBLIGATIONS OF THE COMPANY AND WILL CONTINUE TO ACCRUE INTEREST AND HAVE ALL OF
THE BENEFITS OF THE INDENTURE, INCLUDING BEING CONVERTIBLE INTO SHARES OF THE
COMMON STOCK OF THE COMPANY (THE "REMINGTON COMMON STOCK") AT A CONVERSION PRICE
OF $11.00 PER SHARE, SUBJECT TO THE TERMS OF THE INDENTURE.
 
                                                   (Continued on following page)
 
January 20, 1999
<PAGE>   2
(Continued from preceding page)
 
     Any holder of Notes (a "Holder") desiring to tender all or any portion of
such Holder's Notes must comply with the procedures for tendering Notes set
forth herein in "Procedures for Tendering Notes" and in the Letter of
Transmittal. Tenders of Notes may be withdrawn at any time prior to the
Expiration Date. In the event of a withdrawal of Notes, the Notes so withdrawn
will be promptly returned to the Holder.
 
     THIS OFFER TO PURCHASE IS REQUIRED TO BE MADE UNDER THE INDENTURE. THIS
OFFER TO PURCHASE IS GOVERNED BY THE INDENTURE AND APPLICABLE LAW AND DOES NOT
CONSTITUTE A REDEMPTION OF, OR AN ELECTION BY THE COMPANY TO REDEEM, THE NOTES.
HOLDERS HAVE AN ELECTION WHETHER OR NOT TO ACCEPT THE OFFER.
 
     The Offer is being made pursuant to the Indenture, dated as of December 1,
1992 (the "Indenture"), between the Company and United States Trust Company of
New York, as Trustee (the "Trustee"), which provides that, following a change in
control (as defined in the Indenture), each Holder will have the right, at such
Holder's option, to require the Company to repurchase all or a portion of such
Holder's Notes at the Purchase Price (a "Change in Control Right"). A Change in
Control (as defined herein) occurred on December 28, 1998, as a result of the
Company's recapitalization of its two classes of common stock into Remington
Common Stock, all the shares of which carry one vote (the "Recapitalization").
As a result of the Recapitalization, former holders of the Company's Class A
(Voting ) Stock no longer held a majority of the voting control of the Company,
triggering a change of control provision in the Indenture.
 
     Through January 15, 1999, the last closing price expressed as a percent of
principal amount of the Notes, as reported on the Nasdaq SmallCap Market was
97%. The last reported sale occurred on January 12, 1999. The closing price per
share of Remington Common Stock, as reported on the Nasdaq National Market
System was $3.188 on January 15, 1999.
 
     Tenders of Notes may be withdrawn at any time prior to the Expiration Date.
In the event of a termination of the Offer, the Notes tendered pursuant to the
Offer will be promptly returned to the tendering Holders.
 
     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) and applicable law, the Company will purchase by accepting for
payment, and will pay for, all Notes validly tendered (and not properly
withdrawn) pursuant to the Offer on the Payment Date, and such payment will be
made by the deposit of immediately available funds by the Company with United
States Trust Company of New York (the "Depositary"), which will act as agent for
tendering Holders for the purpose of receiving payment from the Company and
transmitting such payment to tendering Holders.
 
     No person has been authorized to give any information or to make any
representations directly related to this Offer other than those contained in
this Offer to Purchase and, if given or made, such information or
representations must not be relied upon as having been authorized. This Offer to
Purchase and related documents do not constitute an offer to buy or the
solicitation of an offer to sell securities in any circumstances in which such
offer or solicitation is unlawful. The delivery of this Offer to Purchase shall
not, under any circumstances, create any implication that the information
contained herein is current as of any time subsequent to the date of such
information.
 
     Any questions or requests for assistance or for additional copies of this
Offer to Purchase or related documents may be directed to the Depositary at one
of its telephone numbers set forth on the back cover page hereof. Any beneficial
owner owning interests in Notes may contact such beneficial owner's broker,

                                   THE OFFER
GENERAL
 
BECAUSE A CHANGE OF CONTROL AS DEFINED IN THE INDENTURE OCCURRED, THE COMPANY IS
REQUIRED TO MAKE THIS OFFER TO PURCHASE. IF NO CHANGE OF CONTROL HAD OCCURRED,
THE COMPANY WOULD NOT OFFER TO PURCHASE THE NOTES. THE COMPANY DOES NOT BELIEVE
THAT PURCHASING THE NOTES AT THIS TIME IS THE BEST USE OF THE COMPANY'S CAPITAL
OR CREDIT RESOURCES. NO ACTION BY THE NOTE HOLDER IS REQUIRED UNLESS THE NOTE
HOLDER WISHES TO TENDER NOTES UNDER THIS OFFER TO PURCHASE. NOTES NOT TENDERED
WILL REMAIN OBLIGATIONS OF THE COMPANY UNDER THE TERMS AND CONDITIONS OF THE
INDENTURE. SEE "BEST USE OF COMPANY'S RESOURCES."
 
     The Company hereby offers, upon the terms and subject to the conditions set
forth in this Offer to Purchase, to purchase for cash at the Purchase Price any
and all Notes that are properly tendered (and not properly withdrawn), pursuant
to the terms and conditions set forth herein, prior to the Expiration Date. The
Company will accept only tenders of Notes or a portion thereof which are in an
amount equal to $1,000 principal amount of Notes or integral multiples thereof.
Tenders of Notes may be withdrawn at any time prior to the Expiration Date. In
the event of a termination of the Offer, the Notes tendered pursuant to the
Offer will be returned promptly to the tendering Holders.
 
     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) and applicable law, on the Payment Date the Company will purchase
by accepting for payment, and will pay for, all Notes validly tendered (and not
properly withdrawn) pursuant to the Offer. Such payment will be made by the
deposit of immediately available funds by the Company with the Depositary, which
will act as agent for tendering Holders for the purpose of receiving payment
from the Company and transmitting such payment to tendering Holders.
 
     If less than all the principal amount of Notes held by a Holder is tendered
and accepted pursuant to the Offer, the Company will issue, and the Trustee will
authenticate and deliver to or on the order of the Holder thereof, at the
expense of the Company, new Notes of authorized denominations, in principal
amount equal to the portion of the Notes not tendered or not accepted, as the
case may be, as promptly as practicable after the Payment Date.
 
     No Note tendered pursuant to this Offer may be converted into shares of
Remington Common Stock after such Note has been properly tendered to the
Depositary unless the tender of such Note is properly withdrawn, the Company
defaults in payment of the Purchase Price, or the Offer is terminated without
the purchase of Notes.
 
     After the Expiration Date, the Company may purchase additional Notes in the
open market, in privately negotiated transactions, through subsequent tender or
exchange offers or otherwise, subject to compliance with applicable law. Any
future purchases may be on the same terms or on terms that may be more or less
favorable to Holders than the terms of the Offer. Any future purchases will
depend on various factors at that time.
 
PURPOSE AND EFFECTS OF THE OFFER
 
     The Offer is required to be made pursuant to the Indenture, which provides
that upon the occurrence of a Change in Control (as defined below) each Holder
of Notes will have the right, at such Holder's option, to require the Company to
purchase all or a portion of such Holder's Notes, in denominations of $1,000 or
integral multiples thereof, at a purchase price equal to 100% of the principal
amount thereof plus accrued and unpaid interest through the Payment Date. A
"Change in Control" is deemed to have occurred because the shares of the
Company's Class A (Voting) Common Stock and Class B (Non-Voting) Common Stock
were converted into shares of Remington Common Stock, all the shares of which
are entitled to one vote. Prior to the Recapitalization, the Company's Class A
(Voting) shares, while representing a minority of the total
<PAGE>   6
 
outstanding shares of the Company's stock, nonetheless had voting control.
Following the conversion to Remington Common Stock former holders of the Class A
(Voting) shares no longer held a majority of the voting common stock of the
Company. This change in the control status of the Class A (Voting ) stockholders
resulted in a change of control as defined in the Indenture.
 
     This Offer to Purchase serves as the "Change in Control Notice" required by
the Indenture.
 
     The Notes purchased in the Offer will cease to be outstanding and will be
delivered to the Trustee for cancellation immediately after such purchase. Any
Notes which remain outstanding after consummation of the Offer will continue to
be obligations of the Company and will continue to be convertible at the option
of the Holder thereof into shares of Remington Common Stock. The Indenture does
not contain any limitations on the ability of the Company to incur additional
indebtedness.
 
     Holders of Notes that are not tendered pursuant to the Offer will not have
the right after the Expiration Date to exercise their Change in Control Rights
relating to such Notes as a result of the recapitalization of the Company's
common stock. Depending upon, among other things, the amount of Notes
outstanding after the consummation of the Offer, the liquidity of untendered
Notes may be adversely affected by the Offer. If a market for the Notes
continues following the Offer, Notes may trade at a discount compared to present
trading prices depending on prevailing interest rates, the market for securities
with similar credit features, the performance of the Company and other factors.
In addition, if substantially all of the Notes are tendered pursuant to the
Offer, the Company may consider delisting the Notes from the NASDAQ SmallCap
Market. Accordingly, there is no assurance that an active market in the Notes
will exist following consummation of the Offer and no assurance as to the prices
at which the Notes may trade.
 
BEST USE OF COMPANY'S RESOURCES
 
     The Company does not believe that purchasing the Notes at this time is the
best use of the Company's capital or credit resources. Due to the recent and
substantial decline in oil and gas prices, the Company believes that there are,
and will continue to be, attractively priced asset acquisition opportunities
within the Company's core operating areas. Given the substantial cash, borrowing
capacity, and low debt levels of the Company, management and the directors
believe that the Company is positioned to take advantage of these opportunities.
Management believes that it can better pursue its objective of increasing value
to equity owners (including owners of derivative securities such as the Notes,
which are convertible into Remington Common Stock) by utilizing presently
available financial resources to take advantage of these asset acquisition
opportunities rather than using the financial resources to redeem the Notes.
 
EXPIRATION DATE; EXTENSIONS; AMENDMENTS; TERMINATION
 
     The Offer will expire on the Expiration Date, which pursuant to the
Indenture is the fourth business day next preceding the Payment Date, unless
extended pursuant to the procedures set forth herein. The Indenture does not
provide for extending the Offer unless required by law. During any extension of
the Offer, all Notes previously tendered pursuant to the Offer (and not properly
withdrawn) will remain subject to the Offer and may be accepted for payment by
the Company, subject to the withdrawal rights of Holders.
 
     The Company also expressly reserves the right, subject to the requirements
of the Indenture and applicable law, to amend the terms of the Offer in any
respect.
 
     Any extension, termination or amendment of the Offer will be followed as
promptly as practicable by a public announcement thereof. Without limiting the
manner in which the Company may choose to make a public announcement of any
extension, termination or amendment of the Offer, the Company shall have no
obligation to publish, advertise or otherwise communicate any such public
announcement, other than by issuing a release to the Dow Jones News Service,
except in the case of an announcement of an extension of the Offer, in which
case the Company shall have no obligation to publish, advertise or otherwise
communicate such announcement other than by issuing a notice of such extension
by press release or other public announcement, which notice shall be issued no
later than 9:00 a.m., New York City time, on the next business day following the
previously scheduled Expiration Date.

ACCEPTANCE FOR PAYMENT
 
     Upon the terms and subject to the conditions to the Offer (including if the
Offer is extended or amended, the terms of such extension or amendment) and
applicable law, the Company will purchase by accepting for payment, and will pay
for, all Notes properly tendered (and not properly withdrawn) pursuant to the
Offer, on the Payment Date. In all cases, payment by the Depositary to tendering
Holders will be made only after timely receipt by the Depositary of the
documentation described under "Procedures for Tendering Notes -- Tendering
Notes."
 
     For purposes of the Offer, the Company shall be deemed to have accepted for
payment (and thereby to have purchased) tendered Notes, if and when the Company
gives oral or written notice to the Depositary of the Company's acceptance of
such Notes for payment. Subject to the terms and conditions of the Offer,
payment for Notes so accepted will be made by deposit of the consideration
therefor with the Depositary. The Depositary will act as agent for tendering
Holders for the purpose of receiving payment from the Company and then
transmitting payment to such tendering Holders.
 
                         PROCEDURES FOR TENDERING NOTES
 
TENDERING NOTES
 
     The tender of Notes pursuant to any of the procedures set forth in this
Offer to Purchase and in the Letter of Transmittal will constitute a binding
agreement between the tendering Holder and the Company upon the terms and
subject to the conditions of the Offer. The tender of Notes will constitute an
agreement to deliver good and marketable title to all tendered Notes prior to
the Expiration Date free and clear of all liens, charges, claims, encumbrances,
interests and restrictions of any kind.
 
     EXCEPT AS PROVIDED IN "-- GUARANTEED DELIVERY PROCEDURES," UNLESS THE NOTES
BEING TENDERED ARE DEPOSITED BY THE HOLDER WITH THE DEPOSITARY PRIOR TO THE
EXPIRATION DATE (ACCOMPANIED BY A PROPERLY COMPLETED AND DULY EXECUTED LETTER OF
TRANSMITTAL), THE COMPANY MAY, AT ITS OPTION, REJECT SUCH TENDER. PAYMENT FOR
NOTES WILL BE MADE ONLY AGAINST DEPOSIT OF TENDERED NOTES AND DELIVERY OF ALL
OTHER REQUIRED DOCUMENTS.
 
     Only record Holders of Notes are authorized to exercise a Change in Control
Right and tender their Notes pursuant to the Offer. Accordingly, to properly
exercise a Change in Control Right and tender Notes or cause Notes to be
tendered, the following procedures must be followed:
 
          NOTES HELD THROUGH DTC. Each beneficial owner of Notes who wishes to
     tender Notes held through a participant (a "DTC Participant") of The
     Depository Trust Company ("DTC") (i.e., a custodian bank, depositary,
     broker, trust company or other nominee) must instruct such DTC Participant
     to cause its Notes to be tendered in accordance with the procedures set
     forth in this Offer to Purchase.
 
          Pursuant to an authorization given by DTC to the DTC Participants,
     each DTC Participant that holds Notes through DTC must (i) transmit its
     acceptance through the DTC Automated Tender Offer Program ("ATOP") (for
     which the transaction will be eligible), and DTC will then edit and verify
     the acceptance, execute a book-entry delivery to the Depositary's account
     at DTC and send an Agent's Message (as defined below) to the Depositary for
     its acceptance or (ii) comply with the guaranteed delivery procedures set
     forth in this Offer to Purchase. Promptly after the date of this Offer to
     Purchase, the Depositary will establish accounts at DTC for purposes of the
     Offer with respect to Notes held through DTC, and any financial institution
     that is a DTC Participant may make book-entry delivery of interests in
     Notes into the Depositary's account through ATOP. Although delivery of
     interests in the Notes may be effected through book-entry transfer into the
     Depositary's account through ATOP, an Agent's Message in connection with
     such book-entry transfer, and any other required documents, must, in any
     case, be transmitted to and received by the Depositary at its address set
     forth on the back cover of this Offer to Purchase, or the guaranteed
     delivery procedures set forth below must be complied with, in each case,
     prior to the Expiration Date. Delivery of documents to DTC does not
     constitute delivery to the
 
                                        3
<PAGE>   8
 
     Depositary. The confirmation of a book-entry transfer into the Depositary's
     account at DTC, as described above, is referred to herein as a "Book-Entry
     Confirmation."
 
          The term "Agent's Message" means a message transmitted by DTC to, and
     received by, the Depositary and forming a part of the Book-Entry
     Confirmation, which states that DTC has received an express acknowledgment
     from each DTC Participant tendering through ATOP that such DTC Participant
     has received a Letter of Transmittal and agrees to be bound by the terms of
     the Letter of Transmittal and that the Company may enforce such agreement
     against such DTC Participant.
 
          All Notes currently held through DTC have been issued in the form of a
     global note registered in the name of Cede & Co., DTC's nominee (the
     "Global Note"). At or as of the Expiration Date, DTC will deliver to the
     Depositary a properly completed and duly executed Letter of Transmittal
     with respect to the aggregate principal amount of Notes as to which it has
     delivered Agent's Messages, and Cede & Co. will deliver to the Depositary
     the Global Note. At or as of the close of business on the third business
     day after the Expiration Date, DTC will deliver to the Depositary a
     properly completed and duly executed Letter of Transmittal for the
     aggregate principal amount of Notes as to which it has delivered Agent's
     Messages relating to Notices of Guaranteed Delivery as described under
     "-- Guaranteed Delivery Procedures." Thereafter, the aggregate principal
     amount of the Global Note will be reduced to represent the aggregate
     principal amount of Notes held through DTC and not tendered pursuant to the
     Offer, and the Global Note will be returned to Cede & Co.
 
          NOTES HELD BY RECORD HOLDERS. Each record Holder who wishes to tender
     Notes must complete and sign a Letter of Transmittal and mail or deliver
     such Letter of Transmittal and any other documents required by the Letter
     of Transmittal together with certificate(s) representing all tendered
     Notes, to the Depositary at its address set forth on the back cover page of
     this Offer to Purchase, or the Holder must comply with the guaranteed
     delivery procedures set forth in this Offer to Purchase.
 
          All signatures on a Letter of Transmittal must be guaranteed by a
     recognized participant in the Securities Transfer Agents Medallion Program,
     the NYSE Medallion Signature Program or the Stock Exchange Medallion
     Program; provided, however, that signatures on a Letter of Transmittal need
     not be guaranteed if such Notes are tendered for the account of an Eligible
     Institution (as defined herein). If a Letter of Transmittal or any Note is
     signed by a trustee, executor, administrator, guardian, attorney-in-fact,
     agent, officer of a corporation or other person acting in a fiduciary or
     representative capacity, such person must so indicate when signing and
     submit proper evidence satisfactory to the Company of the authority of such
     person so to act.
 
          No alternative, conditional, irregular or contingent tenders will be
     accepted (unless waived). By executing a Letter of Transmittal or
     transmitting an acceptance through ATOP, each tendering Holder waives any
     right to receive any notice of the acceptance for purchase of its Notes.
 
          LOST OR MISSING CERTIFICATES. If a record Holder desires to tender
     Notes pursuant to the Offer, but the certificates representing such Notes
     have been mutilated, lost, stolen or destroyed, such Holder should write to
     or telephone the Trustee about procedures for obtaining replacement
     certificates representing such Notes, arranging for indemnification or any
     other matter which requires handling by the Trustee.
 
          BACKUP FEDERAL INCOME TAX WITHHOLDING. Under the "backup withholding"
     provisions of federal income tax law, unless a tendering Holder or his or
     her assignee (in either case, the "Payee") satisfies the conditions
     described in Instruction 5 of the Letter of Transmittal or is otherwise
     exempt, the aggregate purchase price may be subject to backup withholding
     tax at a rate of 31%. To prevent backup withholding, each Payee should
     complete and sign the Substitute Form W-9 provided in the Letter of
     Transmittal. See Instruction 5 of the Letter of Transmittal.
 
          EFFECT OF LETTER OF TRANSMITTAL. Subject to, and effective upon the
     acceptance for, purchase of and payment for Notes tendered thereby, by
     executing and delivering a Letter of Transmittal a tendering Holder (i)
     irrevocably sells, assigns and transfers to the Company, all right, title
     and interest in and to all Notes tendered thereby, (ii) waives any and all
     rights with respect to such Notes (including without
                                        4
<PAGE>   9
 
     limitation any existing or past defaults and their consequences with
     respect to such Notes and the Indenture), (iii) releases and discharges the
     Company from any and all claims such Holder may have now or may have in the
     future arising out of, or related to, such Notes, including without
     limitation any claim that such Holder is entitled to receive additional
     principal or interest payments with respect to such Notes or to participate
     in any redemption or defeasance of the Notes and (iv) irrevocably
     constitutes and appoints the Depositary the true and lawful agent and
     attorney-in-fact of such Holder with respect to any such Notes, with full
     power of substitution and resubstitution (such power of attorney being
     deemed to be an irrevocable power coupled with an interest) to (a) deliver
     certificates representing such Notes, or transfer ownership of such Notes,
     on the account books maintained by DTC, together, in any such case, with
     all accompanying evidences of transfer and authenticity, to the Company,
     (b) present such Notes for transfer on the relevant security register and
     (c) receive all benefits or otherwise exercise all rights of beneficial
     ownership of such Notes (except that the Depositary will have no rights to,
     or control over, funds from the Company, except as agent for the Company,
     for the Purchase Price for any tendered Notes that are purchased by the
     Company), all in accordance with the terms of the Offer.
 
          All questions as to the validity, form, eligibility (including time of
     receipt) and acceptance of tendered Notes will be resolved by the Company,
     whose determination will be final and binding. The Company reserves the
     absolute right to reject any or all tenders that are not in proper form or
     the acceptance of which may, in the opinion of counsel for the Company, be
     unlawful. The Company also reserves the absolute right to waive any
     condition to the Offer and any irregularities or conditions of tender as to
     particular Notes. The Company's interpretation of the terms and conditions
     of the Offer (including the instructions in the Letter of Transmittal) will
     be final and binding. Unless waived, any irregularities in connection with
     tenders must be cured within such time as the Company shall determine. The
     Company and the Depositary shall not be under any duty to give notification
     of defects in such tenders and shall not incur liabilities for failure to
     give such notification. Tenders of Notes will not be deemed to have been
     made until such irregularities have been cured or waived. Any Notes
     received by the Depositary that are not properly tendered and as to which
     the irregularities have not been cured or waived will be returned by the
     Depositary to the tendering Holder, unless otherwise provided in the Letter
     of Transmittal, as soon as practicable following the Expiration Date.
 
     LETTERS OF TRANSMITTAL AND NOTES MUST BE SENT ONLY TO THE DEPOSITARY. DO
NOT SEND LETTERS OF TRANSMITTAL OR NOTES TO THE COMPANY.
 
     THE METHOD OF DELIVERY OF NOTES AND LETTERS OF TRANSMITTAL, ANY REQUIRED
SIGNATURE GUARANTEES AND ALL OTHER REQUIRED DOCUMENTS, INCLUDING DELIVERY
THROUGH DTC AND ANY ACCEPTANCE THROUGH ATOP, IS AT THE ELECTION AND RISK OF THE
PERSONS TENDERING AND DELIVERING ACCEPTANCES OR LETTERS OF TRANSMITTAL, AND,
EXCEPT AS OTHERWISE PROVIDED IN THE LETTER OF TRANSMITTAL, DELIVERY WILL BE
DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE DEPOSITARY. IF DELIVERY IS BY
MAIL, IT IS SUGGESTED THAT THE HOLDER USE PROPERLY INSURED, REGISTERED MAIL WITH
RETURN RECEIPT REQUESTED, AND THAT THE MAILING BE MADE SUFFICIENTLY IN ADVANCE
OF THE EXPIRATION DATE TO PERMIT DELIVERY TO THE DEPOSITARY PRIOR TO THE
EXPIRATION DATE.
 
GUARANTEED DELIVERY PROCEDURES
 
     DTC PARTICIPANTS. A DTC Participant who wishes to cause its Notes to be
tendered, but who cannot transmit its acceptance through ATOP prior to the
Expiration Date, may cause a tender to be effected if:
 
          (a) guaranteed delivery is made by or through a firm or other entity
     identified in Rule 17Ad-15 under the Exchange Act (an "Eligible
     Institution"), including (as such terms are defined therein): (i) a bank;
     (ii) a broker, dealer, municipal securities dealer, municipal securities
     broker, government securities dealer or government securities broker; (iii)
     a credit union; (iv) a national securities exchange, registered securities

     participant in a Securities Transfer Association recognized program; and
 
          (b) prior to 12:00 noon, New York City time, on the Expiration Date,
     the Depositary receives from such Eligible Institution a properly completed
     and duly executed Notice of Guaranteed Delivery (by
 
                                        5
<PAGE>   10
 
     mail, hand delivery, facsimile transmission or overnight courier)
     substantially in the form provided herewith; and
 
          (c) Book-Entry Confirmation of the transfer into the Depositary's
     account at DTC, and all other documents required by the Letter of
     Transmittal, are received by the Depositary within three New York Stock
     Exchange trading days after the date of receipt by the Depositary of such
     Notice of Guaranteed Delivery.
 
     RECORD HOLDERS. A record Holder who wishes to tender its Notes but (x)
whose Notes are not immediately available and will not be available for
tendering prior to the Expiration Date or (y) who cannot deliver its Notes, the
Letter of Transmittal, or any other required documents to the Depositary prior
to the Expiration Date, may effect a tender if:
 
          (a) the tender is made by or through an Eligible Institution; and
 
          (b) prior to 12:00 noon, New York City time, on the Expiration Date,
     the Depositary receives from such Eligible Institution a properly completed
     and duly executed Notice of Guaranteed Delivery (by mail, hand delivery,
     facsimile transmission or overnight courier) substantially in the form
     provided herewith; and
 
          (c) a properly completed and executed Letter of Transmittal, as well
     as the certificate(s) representing all tendered Notes in proper form for
     transfer, and all other documents required by the Letter of Transmittal,
     are received by the Depositary within three New York Stock Exchange trading
     days after the date of receipt by the Depositary of such Notice of
     Guaranteed Delivery.
 
     Under no circumstances will interest be paid by the Company by reason of
any delay in making payment to any person using the guaranteed delivery
procedures described above.
 
WITHDRAWAL RIGHTS
 
     Tenders of Notes (or any portion of such Notes in integral multiples of
$1,000) may be withdrawn at any time prior to the Expiration Date.
 
     NOTES HELD THROUGH DTC. A DTC Participant who has transmitted its
acceptance through ATOP of Notes held through DTC may, prior to the Expiration
Date, withdraw the instruction given thereby by (i) withdrawing its acceptance
through ATOP or (ii) delivering to the Depositary by mail, hand delivery or
facsimile transmission a notice of withdrawal of such instruction. Such notice
of withdrawal must contain the name and number of the DTC Participant, the
principal amount of Notes to which such withdrawal relates and the signature of
the DTC Participant. Withdrawal of such an instruction will be effective upon
receipt of such notice of withdrawal by the Depositary.
 
     NOTES HELD BY RECORD HOLDERS. A Holder may withdraw its tender of Notes,
prior to the Expiration Date, by delivering to the Depositary by mail, hand
delivery or facsimile transmission a notice of withdrawal. Any such notice of
withdrawal must (i) specify the name of the person who tendered the Notes to be
withdrawn, (ii) contain a description of the Notes to be withdrawn and identify
the certificate number or numbers shown on the particular certificates
evidencing such Notes and the aggregate principal amount represented by such
Notes and (iii) be signed by the Holder of such Notes in the same manner as the
original signature on the Letter of Transmittal by which such Notes were
tendered (including any required signature guarantees), or be signed by another
person and accompanied by (x) documents of transfer in a form acceptable to the
Company, in its sole discretion, and (y) a properly completed irrevocable proxy
that authorizes such person to effect such revocation on behalf of such Holder.
If the Notes to be withdrawn have been delivered or otherwise identified to the
Depositary, a signed notice of withdrawal is effective immediately upon receipt
by the Depositary even if physical release is not yet effected. Any Notes
properly withdrawn will be deemed not to be validly tendered for purposes of the
Offer.
 
     All signatures on a notice of withdrawal must be guaranteed by a recognized
participant in the Securities Transfer Agents Medallion Program, the NYSE
Medallion Signature Program or the Stock Exchange
 
                                        6
<PAGE>   11
 
Medallion Program; provided, however, that signatures on the notice of
withdrawal need not be guaranteed if the Notes being withdrawn are held for the
account of an Eligible Institution.
 
     A withdrawal of an instruction or a withdrawal of a tender must be executed
by a DTC Participant or a Holder, as the case may be, in the same manner as the
person's name appears on its transmission through ATOP or Letter of Transmittal,
as the case may be, to which such withdrawal relates. If a notice of withdrawal
is signed by a trustee, partner, executor, administrator, guardian,
attorney-in-fact, agent, officer of a corporation or other person acting in a
fiduciary or representative capacity, such person must so indicate when signing
and must submit with the revocation appropriate evidence of authority to execute
the notice of withdrawal. A Holder or DTC Participant may withdraw a tender only
if such withdrawal complies with the provisions of this Offer to Purchase.
 
     A withdrawal of an instruction previously given pursuant to the
transmission of an acceptance through ATOP or a withdrawal of a tender by a
Holder may be rescinded only by (i) a new transmission of acceptance through

                   CERTAIN INFORMATION CONCERNING THE COMPANY
 
     The Company is an independent exploration and production company primarily
engaged in the exploration for, and the development of, oil and natural gas. The
Company was initially organized in 1981 as OKC Limited Partnership (the
"Predecessor Partnership") and converted to a corporation in 1992. The Company's
name was changed from Box Energy Corporation to Remington Oil and Gas
Corporation in December 1997. The Company is a Delaware corporation with
executive offices located at 8201 Preston Road, Suite 600, Dallas, Texas
75225-6211, telephone number (214) 210-2650.
 
                              RECENT DEVELOPMENTS
 
CHANGE IN CONTROL
 
     The Company filed a Certificate of Merger and Restated Certificate of
Incorporation with the Secretary of State of the State of Delaware effective
December 28, 1998. Under the Certificate of Merger, S-Sixteen Holding Company
("SSHC") was merged into the Company pursuant to the Agreement and Plan of
Merger between the Company and SSHC dated as of June 22, 1998 (the "Merger
Agreement"). In addition, the Merger Agreement and the Company's Restated
Certificate of Incorporation provided for the recapitalization of the Company's
Common Stock from two classes of common stock, only one class of which carried
voting rights, to a single class of common stock, all the shares of which have
an equal vote. The Merger Agreement was approved by the Company's Stockholders
on December 23, 1998. The Recapitalization was effective on December 28, 1998.
Prior to the Recapitalization, the Company's Class A Stock, while representing
only 15.8% of the outstanding equity of the Company, held exclusive voting
rights. Following the Recapitalization, the Class A (Voting) shares were
converted into shares of the Company's Common Stock representing approximately
17.3% of the outstanding equity (the "Conversion Percentage"). Because the
Conversion Percentage is less than 50% following the Recapitalization, a change
of control provision in the Indenture was triggered.
 
OPERATIONS UPDATE
 
                          FORWARD-LOOKING INFORMATION
 
     This Offer to Purchase includes forward-looking statements within the
meaning of Section 27A of the Securities Act and Section 21E of the Exchange
Act. All statements other than statements of historical fact included in this
Offer to Purchase are forward-looking statements. Although Remington believes
that its expectations are based upon reasonable assumptions, no assurance can be
given that actual results may not differ materially from those in the
forward-looking statements. Important factors that could cause actual
                                        7
<PAGE>   12
 
results to vary materially from the expectations of Remington include, among
other things, the prices received or the demand for oil and gas, the uncertainty
of reserve estimates, operating hazards, competition and the effects of
governmental and environmental regulation and conditions in the capital and
equity markets as well as other factors discussed or incorporated by reference
in this Offer to Purchase.
 
     During 1997 and 1998, the management of the Company repositioned the
Company. As compared to 1996, the Company estimates that 1998 results of
operations will include reductions of operating costs by approximately 33%,
general and administrative expenses by approximately 50%, and dry hole costs by
approximately 87%. At January 1, 1998, quantities of oil and gas reserves were
approximately 7% higher than at January 1, 1997. Management expects another
increase in quantities of reserves at January 1, 1999. In addition to reducing
overall general and administrative costs significantly, the Company has been
staffed with highly qualified technical personnel who have been provided an
extensive 3-d seismic data base and the computer software and hardware to
efficiently utilize this data base. The Company's capital budget in early 1999
is dedicated to projects that are expected to result in near term production
increases, which the Company believes will help to achieve its goal of a 35%
production increase in 1999 over 1998 levels. Drilling has commenced at Main
Pass 262 in the Gulf of Mexico, where if the planned sidetrack and deepening of
the #3 well is successful, production through the existing platform can be
commenced immediately after completing the well. Additional developmental
drilling is planned in South Pass Block 87 and Eugene Island 135 to commence
late in January or early February 1999. If the drilling is successful,
production can be commenced through existing platforms immediately after
completing these wells. Two wells are planned in south Texas on an extensive 3-d
survey conducted in 1997 and 1998. If successful, production can be established
quickly on these properties. Approximately $15 million of the Company's $25
million budget for 1999 is dedicated to projects that can result in near term
production increases. The remainder of the Company's planned budget for 1999,
which is designed to stay within available cash flow, will be dedicated to
longer term investments in acreage and prospects for the future.
 
NOTES CONVERTIBLE INTO SHARES OF REMINGTON COMMON STOCK
 
     As a result of the Recapitalization, the Notes are now convertible into
shares of Remington Common Stock, all the shares of which have an equal vote,
and are no longer convertible into shares of the Class B (Non-Voting) Common
Stock. A Supplemental Indenture regarding this change will be filed by the
Company with the Trustee of the Notes.
 
BANK CREDIT AGREEMENT
 
     On September 30, 1998, the Company extended and increased its bank
revolving credit facility with Comerica Bank -- Texas. The extended credit
facility provides for a maximum of $50 million and has a term of 18 months. The
initial borrowing base under the facility is $15 million with an automatic
increase to $20 million in the event no more than $10 million of the Notes are
tendered. The borrowing base is also subject to amortization of $1.25 million
per month ($1.67 million in case of a $20 million borrowing base) starting in
April 1999, if the Company fails to increase reserves as specified in the credit
agreement. Likewise, the borrowing base is subject to increase as reserves
increase in accordance with the loan agreement. Up to $15 million of the funds
available through the credit facility may be used for general corporate
purposes. Amounts advanced in excess of the $15 million may be used to acquire
producing oil and gas properties. The Company's oil and gas properties serve as
collateral for the credit facility. The Company is in discussions with the bank
regarding an increase in the borrowing base under the credit facility based on
reserve additions associated with the 1998 drilling program, along with the
properties acquired from UPRC in December 1998 and the oil pipeline acquired in
the merger and Recapitalization completed December 28, 1998. As of January 18,
1999, the loan balance was $3.5 million, and letters of credit aggregating
$250,000 were outstanding under the facility.
 
     Borrowings under the credit facility bear interest at the lender's floating
base rate plus up to one-half percentage point depending on utilization as
defined in the credit agreement. The present interest rate is 7.75% per annum.
The Company also has an option to borrow at rates based on the London Interbank
Offered Rates ("LIBOR"). To date the Company has not utilized the LIBOR option.

                          SOURCES AND AMOUNT OF FUNDS
 
     The precise amount of funds required by the Company to purchase Notes
tendered pursuant to the Offer and to pay the fees and expenses related to the
Offer will not be known until the Expiration Date. If all outstanding Notes were
tendered and purchased, the aggregate amount of funds required to pay the
Purchase Price would be $39,118,467. The Company has not arranged permanent
financing to fund the purchase of the Notes. Management anticipates utilizing
available working capital and current revolving bank line of credit financing
plus, to the extent necessary, arranging additional bank credit and/or issuing
preferred stock sufficient to cover amounts in excess of currently available
funds. There can be no assurance, however, that sufficient additional bank
credit will be made available to the Company.

                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
     The following discussion is for general information only and is based on
the federal income tax law now in effect, which is subject to change, possibly
retroactively. This summary does not discuss all aspects of federal income
taxation which may be relevant to any particular Holder in light of such
Holder's individual investment circumstances or to certain types of Holders
subject to special tax rules (e.g., financial institutions, broker-dealers,
insurance companies, tax-exempt organizations, and foreign taxpayers), nor does
it address specific state, local or foreign tax consequences. This summary
assumes that Holders have held their Notes as "capital assets" under the
Internal Revenue Code of 1986, as amended. EACH HOLDER IS URGED TO CONSULT SUCH
HOLDER'S TAX ADVISOR REGARDING THE SPECIFIC FEDERAL, STATE, LOCAL, AND FOREIGN
INCOME AND OTHER TAX CONSEQUENCES OF THE OFFER.
 
     The receipt of cash by a Holder in exchange for Notes will be a taxable
transaction for federal income tax purposes and may also be a taxable
transaction under applicable state, local or foreign tax laws. Such Holder will
recognize gain or loss in an amount equal to the difference between (i) the
amount of cash received (other than that representing accrued interest) and (ii)
such Holder's adjusted tax basis in the Notes. Subject to the market discount
rules discussed below, such gain or loss will be capital gain or loss. If the
Holder has held such Notes for more than 12 months, the gain will be long-term
gain with a maximum federal income tax rate of 20%. Any capital loss will be
short-term loss if the Notes have been held for 12 months or less and long-term
loss if the Notes have been held for more than 12 months.
 
     The payment of accrued interest on a Note generally will be treated as
ordinary income.
 
     An exception to the capital gain treatment described above applies to a
Holder who holds a Note with a "market discount." Market discount is the amount
by which the Holder's basis in the Note immediately after its acquisition is
exceeded by the stated redemption price of the Note at maturity. A Note,
however, will be considered to have no market discount if such excess is less
than 1/4 of 1% of the stated redemption price of the Note at maturity multiplied
by the number of complete years from the Holder's acquisition date of the Note
to its maturity date. The gain realized by the Holder of a market discount Note
on its purchase by the Company will be treated as ordinary income to the extent
that a market discount has accrued (on a straight line basis or, at the election
of the Holder, on a constant interest basis) from the Holder's acquisition date
to the date of sale, unless the Holder has elected to include market discount in
income currently as it accrues. Gain in excess of such accrued market discount
will be subject to the capital gains rules described above.

Ladies and Gentlemen:
 
    Upon the terms and subject to the conditions of the Offer, the undersigned
hereby tenders to the Company the principal amount of Notes indicated above.
 
    Subject to and effective upon the acceptance for purchase of and payment for
Notes tendered thereby, by executing and delivering a Letter of Transmittal a
tendering Holder (i) irrevocably sells, assigns and transfers to the Company,
all right, title and interest in and to all Notes tendered thereby and (ii)
waives any and all rights with respect to such Notes (including without
limitation any existing or past defaults and their consequences with respect to
such Note and the Indenture under which the Notes were issued), (iii) releases
and discharges the Company from any and all claims such Holder may have now, or
may have in the future arising out of, or related to, such Notes including
without limitation any claims that such Holder is entitled to receive additional
principal or interest payments with respect to such Notes or to participate in
any redemption or defeasance of the Notes and (iv) irrevocably constitutes and
appoints the Depositary the true and lawful agent and attorney-in-fact of such
Holder with respect to any such tendered Notes, with full power of substitution
and resubstitution (such power of attorney being deemed to be an irrevocable
power coupled with an interest) to (a) deliver certificates representing such
Notes, or transfer ownership of such Notes, on the account books maintained by
DTC, together, in any such case, with all accompanying evidences of transfer and
authenticity, to the Company, (b) present such Notes for transfer on the
relevant security register and (c) receive all benefits or otherwise exercise
all rights of beneficial ownership of such
<PAGE>   4
 
Notes (except that the Depositary will have no rights to, or control over, funds
from the Company, except as agent for the Company, for the purchase price for
any tendered Notes that are purchased by the Company), all in accordance with
the terms of the Offer.
 
    The undersigned understands that tenders of Notes may be withdrawn by
written notice of withdrawal received by the Depositary at any time prior to the
Expiration Date. See Instruction 1.
 
    The undersigned hereby represents and warrants that the undersigned (i) owns
the Notes tendered and is entitled to tender such Notes and (ii) has full power
and authority to tender, sell, assign and transfer the Notes tendered hereby and
that when such Notes are accepted for purchase and payment by the Company, the
Company will acquire good title thereto, free and clear of all liens,
restrictions, charges and encumbrances and not subject to any adverse claim or
right. The undersigned will, upon request, execute and deliver any additional
documents deemed by the Depositary or the Company to be necessary or desirable
to complete the sale, assignment and transfer of the Notes tendered hereby.
 
    For the purposes of the Offer, the undersigned understands that the Company
will be deemed to have accepted for purchase validly tendered Notes (or
defectively tendered Notes with respect to which the Company has waived such
defect) only if, as and when the Company gives oral or written notice thereof to
the Depositary. Payment for Notes purchased pursuant to the Offer will be made
by deposit of the purchase price for such Notes with the Depositary, which will
act as agent for tendering Holders for the purpose of receiving payments from
the Company and transmitting such payments to such Holders.
 
    All authority conferred or agreed to be conferred by this Letter of
Transmittal shall survive the death or incapacity of the undersigned, and every
obligation of the undersigned under this Letter of Transmittal shall be binding
upon the undersigned's heirs, personal representatives, executors,
administrators, successors, assigns, trustees in bankruptcy and other legal
representatives.
 
    The undersigned understands that valid tender of Notes pursuant to any one
of the procedures described under "Procedures for Tendering Notes" in the Offer
to Purchase and in the instructions hereto will constitute a binding agreement
between the undersigned and the Company upon the terms and subject to the
conditions of the Offer, including the undersigned's waiver of any existing
defaults and their consequences with respect to the Notes and the Indenture
(including, without limitation, a default in the payment of interest).
 
    The undersigned understands that the delivery and surrender of Notes is not
effective, and the risk of loss of the Notes does not pass to the Depositary,
until receipt by the Depositary of this Letter of Transmittal, or a facsimile
hereof, properly completed and duly executed, together with all accompanying
evidences of authority and any other required documents in form satisfactory to
the Company. All questions as to the validity, form, eligibility (including time
of receipt) and acceptance for payment of any tender of Notes pursuant to the
procedures described in the Offer to Purchase and the form and validity
(including time of receipt of notices of withdrawal) of all documents will be
determined by the Company, in its sole direction, which determination shall be
final and binding on all parties.
 
    Unless otherwise indicated herein under "Special Issuance or Payment
Instructions," the undersigned hereby requests that any Notes representing
principal amounts not tendered be issued in the name(s) of the undersigned, and
checks constituting payments for Notes purchased in connection with the Offer be
issued to the order of the undersigned. Similarly, unless otherwise indicated
herein under "Special Delivery Instructions," the undersigned hereby requests
that any Notes representing principal amounts not tendered and checks
constituting payments for Notes to be purchased in connection with the Offer be
delivered to the undersigned at the address(es) shown herein. In the event that
the "Special Issuance or Payment Instructions" box or the "Special Delivery
Instructions" box, or both, are completed, the undersigned hereby requests that
any Notes representing principal amounts not tendered be issued in the name(s)
of, certificates for such Notes be delivered to, and checks constituting
payments for Notes purchased in connection with the Offer be issued in the
name(s) of, and be delivered to, the person(s) at the address(es) so indicated,
as applicable. The undersigned recognizes that the Company has no obligation
pursuant to the "Special Issuance or Payment Instructions" box to transfer any
Notes from the name of the registered Holder(s) thereof if the Company does not
accept for purchase any of the principal amount of such Notes so tendered.

                                  INSTRUCTIONS
 
             FORMING PART OF THE TERMS AND CONDITIONS OF THE OFFER
 
    1.  Procedures for Tendering Notes; Guaranteed Delivery Procedures;
Withdrawal of Tenders. To tender Notes in the Offer, certificates representing
such Notes, together with a properly completed and duly executed copy (or
facsimile) of this Letter of Transmittal, and any other documents required by
this Letter of Transmittal must be received by the Depositary at one of its
addresses set forth herein prior to the Expiration Date. The method of delivery
of this Letter of Transmittal, certificates for Notes and all other required
documents to the Depositary is at the election and risk of Holders. If such
delivery is to be made by mail, it is suggested that Holders use properly
insured registered mail, return receipt requested, and that the mailing be made
sufficiently in advance of the Expiration Date to permit delivery to the
Depositary prior to such date. Except as otherwise provided below, the delivery
will be deemed made when actually received or confirmed by the Depositary. THIS
LETTER OF TRANSMITTAL AND NOTES SHOULD BE SENT ONLY TO THE DEPOSITARY, AND NOT
TO THE COMPANY OR THE TRUSTEE.
 
    This Letter of Transmittal is also being supplied for informational purposes
only to persons who hold notes in book-entry form through the facilities of DTC.
Tender of Notes held through DTC must be made pursuant to the procedures
described under "Procedures for Tendering Notes -- Tendering Notes -- Notes Held
Through DTC" in the Offer to Purchase.
 
    Except as provided herein for the book-entry or guaranteed delivery
procedures, unless the Notes being tendered are deposited with the Depositary on
or prior to the Expiration Date (accompanied by the appropriate, properly
completed and duly executed Letter of Transmittal and any required signature
guarantees and other documents required by this Letter of Transmittal), the
Company may, in its sole discretion, reject such tender. Payment for Notes will
be made only against deposit of tendered Notes.
 
    By executing this Letter of Transmittal (or a facsimile thereof), a
tendering Holder waives any right to receive any notice of the acceptance for
payment of tendered Notes.
 
    For a full description of the procedures for tendering Notes, see
"Procedures for Tendering Notes -- Tendering Notes" in the Offer to Purchase.
 
    If a Holder desires to tender Notes pursuant to the Offer and (i)
certificates representing such Holder's Notes are not lost but are not
immediately available or time will not permit this Letter of Transmittal,
certificates representing Notes or other required documents to reach the
Depositary on or prior to the Expiration Date or (ii) the procedures for
book-entry transfer cannot be completed on or prior to the Expiration Date, such
Holder may effect a tender of such Notes in accordance with the guaranteed
delivery procedures described under "Procedures for Tendering
Notes -- Guaranteed Delivery Procedures" in the Offer to Purchase.
 
    Tenders of Notes may be withdrawn at any time prior to the Expiration Date
pursuant to the procedures described under "Procedures For Tendering
Notes -- Withdrawal Rights" in the Offer to Purchase.
 
    2.  Partial Tenders. Tenders of Notes pursuant to the Offer will be accepted
only in principal amounts equal to $1,000 or integral multiples thereof. If less
than the entire principal amount of any Notes evidenced by a submitted
certificate is tendered, the tendering Holder must fill in the principal amount
tendered in the last column of the box entitled "Description of Notes" herein.
The entire principal amount represented by the certificates for all Notes
delivered to the Depositary will be deemed to have been tendered unless
otherwise indicated. If the entire principal amount of all Notes is not
tendered, certificates for the principal amount of Notes not tendered will be
sent to the Holder unless otherwise provided in the appropriate box on this
Letter of Transmittal (see Instruction 4), promptly after the Notes are accepted
for purchase.
 
    3.  Signatures on this Letter of Transmittal; Bond Powers and Endorsement;
Guarantee of Signatures. If this Letter of Transmittal is signed by the
registered Holder(s) of the Notes 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 THIS LETTER OF TRANSMITTAL IS EXECUTED BY A HOLDER WHO IS NOT THE
REGISTERED HOLDER, THEN THE REGISTERED HOLDER MUST SIGN A VALID POWER OF
ATTORNEY, WITH THE SIGNATURE OF SUCH REGISTERED HOLDER GUARANTEED BY AN ELIGIBLE
INSTITUTION.
 
    If any of the Notes tendered hereby are owned of record by two or more joint
owners, all such owners must sign this Letter of Transmittal. If any tendered
Notes are registered in different names on several certificates, it will be
necessary to complete, sign and submit as many copies of this Letter of
Transmittal and any necessary accompanying documents as there are different
names in which certificates are held.
 
    If this Letter of Transmittal is signed by the Holder, and the certificates
for any principal amount of Notes not tendered for purchase are to be issued (or
if any principal amount of Notes that is not tendered for purchase is to be
reissued or returned) to the Holder, and checks constituting payments for Notes
to be purchased in connection with the Offer are to be issued to the order of
the Holder, then the Holder need not endorse any certificates for tendered Notes
nor provide a separate bond power. In any other case (including if this Letter
of Transmittal is not signed by the Holder), the Holder must either properly
endorse the certificates for Notes tendered or transmit a separate properly
completed bond power with this Letter of Transmittal (in either case, executed
exactly as the name(s) of the registered Holder(s) appear(s) on such Notes),
with the signature on the endorsement or bond power guaranteed by an Eligible
Institution, unless such certificates or bond powers are executed by an Eligible
Institution.
<PAGE>   8
 
    If this Letter of Transmittal or any certificates representing Notes or bond
powers are signed by trustees, executors, administrators, guardians,
attorneys-in-fact, officers of corporations or others acting in a fiduciary or
representative capacity, such persons should so indicate when signing, and
submit proper evidence satisfactory to the Company of their authority so to act
with this Letter of Transmittal.
 
    Endorsements on certificates for Notes and signatures on bond powers
provided in accordance with this Instruction 3 by registered Holders not
executing this Letter of Transmittal must be guaranteed by an Eligible
Institution.
 
    No signature guarantee is required if: (i) this Letter of Transmittal is
signed by the registered Holder(s) of the Notes tendered herewith and the
payments for the Notes to be purchased are to be made, or any Notes for
principal amounts not tendered for purchase are to be issued, directly to such
registered Holder(s) and neither the "Special Issuance or Payment Instructions"
box nor the "Special Delivery Instructions" box of this Letter of Transmittal
has been completed; or (ii) such Notes are tendered for the account of an
Eligible Institution. In all other cases, all signatures on Letters of
Transmittal accompanying Notes must be guaranteed by an Eligible Institution.
 
    4.  Special Issuance or Payment and Special Delivery Instructions. Tendering
Holders should indicate in the applicable box or boxes the name and address to
which Notes for principal amounts not tendered or not accepted for purchase or
checks constituting payments for Notes to be purchased in connection with the
Offer are to be issued or sent, if different from the name and address of the
Holder signing this Letter of Transmittal. In the case of issuance in a
different name, the taxpayer identification or social security number of the
person named must also be indicated. If no instructions are given, Notes not
tendered or not accepted for purchase will be returned to the Holder of the
Notes tendered.
 
    5.  Taxpayer Identification Number and Substitute Form W-9. Each tendering
Holder is required to provide the Depositary with the Holder's correct taxpayer
identification number ("TIN"), generally the Holder's social security or federal
employer identification number, on Substitute Form W-9, which is provided under
"Important Tax Information" below, or, alternatively, to establish another basis
for exemption from backup withholding. A Holder must cross out item (2) in the
Certification box on Substitute Form W-9 if such Holder is subject to backup
withholding. Failure to provide the information on the form may subject the
tendering Holder to 31% federal income tax backup withholding on the payments
made to the Holder or other payee with respect to Notes purchased pursuant to
the Offer. The box in Part 3 of the form should be checked if the tendering
Holder 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 3 is checked and the Depositary
is not provided with a TIN within 60 days, thereafter the Depositary will
withhold 31% from all such payments with respect to the Notes to be purchased
until a TIN is provided to the Depositary.
 
    6.  Transfer Taxes. The Company will pay all transfer taxes, if any, payable
on the purchase and transfer of Notes purchased pursuant to the Offer, except in
the case of deliveries of certificates for Notes for principal amounts not
tendered for payment that are to be registered or issued in the name of any
person other than the Holder of Notes tendered hereby, in which case the amount
of any transfer taxes (whether imposed on the registered Holder or such other
person) 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 stamps to be affixed to the certificates listed in this Letter of
Transmittal.
 
    7.  Irregularities. All questions as to the validity, form, eligibility
(including the time of receipt) and acceptance for payment of any tenders of
Notes pursuant to the procedures described in the Offer to Purchase and the form
and validity (including the time of receipt of notices of withdrawal) of all
documents will be determined by the Company, in its sole discretion, which
determination shall be final and binding on all parties. The Company reserves
the absolute right to reject any or all tenders determined by it not to be in
proper form or the acceptance of or payment for which may be unlawful. The
Company also reserves the absolute right to waive any of the conditions of the
Offer and any defect or irregularity in the tender of any particular Notes. The
Company's interpretations of the terms and conditions of the Offer (including
without limitation the instructions in this Letter of Transmittal) shall be
final and binding. No alternative, conditional or contingent tenders will be
accepted. Unless waived, any irregularities in connection with tenders must be
cured within such time as the Company shall determine. None of the Company, the
Depositary or any other person will be under any duty to give notification of
any defects or irregularities in such tenders or will incur any liability to
Holders for failure to give such notification. Tenders of such Notes shall not
be deemed to have been made until such irregularities have been cured or waived.
Any Notes received by the Depositary that are not properly tendered and as to
which the irregularities have not been cured or waived will be returned by the
Depositary to the tendering Holders, unless such Holders have otherwise provided
herein, as promptly as practical following the Expiration Date.
 
    8.  Mutilated, Lost, Stolen or Destroyed Certificates for Notes. Any Holder
whose certificates for Notes have been mutilated, lost, stolen or destroyed
should contact the Depositary at the address indicated above for further
instructions.
 
    9.  Requests for Assistance or Additional Copies. Questions relating to the
procedure for tendering Notes and requests for assistance or additional copies
of the Offer to Purchase and this Letter of Transmittal may be directed to, and
additional information about the Offer may be obtained from the Depositary,
whose address and telephone number appears herein.
<PAGE>   9
 
                           IMPORTANT TAX INFORMATION
 
    Under federal income tax laws, a Holder whose tendered Notes are accepted
for payment is required by law to provide the Depositary (as payer) with such
Holder's correct TIN on Substitute Form W-9 included herein or otherwise
establish a basis for exemption from backup withholding. If such Holder is an
individual, the TIN is his social security number. If the Depositary is not
provided with the correct TIN, a $50 penalty may be imposed by the Internal
Revenue Service, and payments made with respect to Notes purchased pursuant to
the Offer may be subject to backup withholding. Failure to comply truthfully
with the backup withholding requirements also may result in the imposition of
severe criminal and/or civil fines and penalties.
 
    Certain Holders (including, among others, all corporations and certain
foreign persons) are not subject to these backup withholding and reporting
requirements. Exempt Holders should furnish their TIN, write "Exempt" on the
face of the Substitute Form W-9, and sign, date and return the Substitute Form
W-9 to the Depositary. A foreign person, including entities, may qualify as an
exempt recipient by submitting to the Depositary a properly completed Internal
Revenue Service Form W-8, signed under penalties of perjury, attesting to that
Holder's foreign status. A Form W-8 can be obtained from the Depositary. 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 payments made to the Holder or other payee. Backup withholding is not an
additional federal income tax. Rather, the federal income 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.
 
PURPOSE OF SUBSTITUTE FORM W-9
 
    To prevent backup withholding on payments made with respect to Notes
purchased pursuant to the Offer, the Holder is required to provide the
Depositary with either: (i) the Holder's correct TIN by completing the form
included herein, certifying that the TIN provided on Substitute Form W-9 is
correct (or that such Holder is awaiting a TIN) and that (A) the Holder has not
been notified by the Internal Revenue Service that the Holder is subject to
backup withholding as a result of failure to report all interest or dividends or
(B) the Internal Revenue Service has notified the Holder that the Holder is no
longer subject to backup withholding; or (ii) an adequate basis for exemption.
<PAGE>   10
 
NUMBER TO GIVE THE DEPOSITARY
 
    The Holder is required to give the Depositary the TIN (e.g., social security
number or employer identification number) of the registered Holder of the Notes.
If the Notes are held in more than one name or are held not in the name of the
actual owner, consult the enclosed "Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9" for additional guidance on which
number to report.

To our clients:
 
     Enclosed for your consideration is a Change in Control Notice and Offer to
Purchase, dated January 20, 1999 (as the same may be amended from time to time,
the "Offer to Purchase"), and a form of Letter of Transmittal and instructions

all of its outstanding 8 1/4% Convertible Subordinated Notes due 2002 (the
"Notes") at 100% of the principal amount thereof, plus accrued interest thereon

     The materials are being forwarded to you as the beneficial owner of Notes
carried by us for your account or benefit but not registered in your name. A
tender of any Notes may only be made by us as the registered Holder and pursuant
to your instructions.
 
     Accordingly, we request instructions as to whether you wish us to tender

Transmittal. We urge you to read carefully the Offer to Purchase and Letter of

to Purchase, at any time prior to the Expiration Date.

     the Company to redeem, the Notes. Holders have an election whether or not
     to accept the Offer. As stated above and discussed in the accompanying
     materials, the Company does not believe that purchasing the Notes at this
     time is the best use of the Company's capital or credit resources.
 
          2. The Offer is for any and all outstanding Notes.
 
          3. The Offer and withdrawal rights will expire on the Expiration Date.

     tendering Holder to the Company will be paid by the Company, except as
     provided in the Offer to Purchase and the instructions to the Letter of
     Transmittal.

account or benefit, please so instruct us by completing, executing and returning
to us the instruction form that appears below. If you authorize the tender of
your Notes, all such Notes will be tendered unless otherwise specified below.
THE ACCOMPANYING LETTER OF TRANSMITTAL IS FURNISHED TO YOU FOR INFORMATIONAL

REGISTERED IN OUR NAME FOR YOUR ACCOUNT OR BENEFIT.

                              AMENDED AND RESTATED
                   SECURED AND REVOLVING CREDIT LOAN AGREEMENT


         THIS AMENDED AND RESTATED SECURED REVOLVING CREDIT LOAN AGREEMENT is
entered into September 30, 1998 by and between REMINGTON OIL AND GAS

                                   ARTICLE II
                              REVOLVING CREDIT LOAN


         2.1      REVOLVING LOAN COMMITMENT.

                  Subject to and upon the terms and conditions herein set forth,
Bank agrees to lend funds to Borrower and to issue Letters of Credit for the
account of Borrower at any time and from time to time during the Availability
Period (each advance made by Bank hereunder called an "Advance", and the
aggregate balance of Advances made by Bank hereunder, less repayments of
principal, are herein collectively called the "Revolving Credit Loan"), provided
that the sum of the aggregate Revolving Credit Loans and Letter of Credit
Exposure outstanding at any time shall not exceed the lesser of (i) $50,000,000
or (ii) the Borrowing Base from time to time in effect (such lesser amount being
the "Commitment"). Subject to the foregoing limitations and the requirements set
forth in Section 2.4 hereof, Borrower may borrow, repay without penalty or
premium (other than required in certain events by Section 3.3(h) and reborrow
hereunder, during the Availability Period.

         2.2      BORROWING BASE CONSIDERATIONS.

                  (a)      Initial Borrowing Base.

                           Commencing on the date hereof the Borrowing Base 
shall be $15,000,000.00 until redetermined in accordance with this Section 2.2;
provided, however, if the Merger occurs on or prior to December 31, 1998 and if,
as a result of the Merger, no more than an aggregate $10,000,000 in face amount
of the Subordinated Indebtedness is tendered by the holders thereof for payment
within the time alloted therefor in the Indenture governing such Subordinated
Indebtedness, then, as of the Business Day next succeeding the last Business Day
on which such Indebtedness may be tendered for payment as a result of the
Merger, the Borrowing Base shall automatically increase to $20,000,000;
provided, further, that the Borrowing Base will automatically and without any
action by Bank decline by $1,250,000 ($1,667,667 if the Borrowing Base on March
30, 1999 is $20,000,000) on the first day of each and every month commencing
April 1, 1999 unless such reduction schedule is revised by Bank pursuant to
Section 2.2(b). Such automatic reductions in the Borrowing Base may require
payments by Borrower pursuant to Section 2.2(d).

                  (b)      Subsequent Determination of Borrowing Base.

                           The Borrowing Base, and the amount of the automatic,
monthly reductions in the Borrowing Base, shall be redetermined as of each March
30 and September 30 during the Availability Period (the "Determination Date").
Borrower shall deliver to Bank on or before each January 31 and July 31, (i)
such information, reports and other data pertaining to the reserves


                                        2

<PAGE>   7



attributable to the Mortgaged Properties, in form and substance acceptable to
Bank and as Bank shall reasonably require, which information, reports and other
data shall evaluate (A) the reserves attributable to the Mortgaged Properties,
and (B) the reserves attributable to such other Mineral Interests as Borrower
desires to be considered for Borrowing Base purposes (such evaluation shall
include, without limitation, a description of reserves, rates of production,
gross revenues, operating expenses, ad valorem taxes, capital costs, net
revenues and present value of future net revenues attributable to such reserves
and production therefrom, and a statement of the assumptions upon which such
determinations were made)(provided that the information delivered to Bank on
January 31 of each year shall include a reserve report on the Mortgaged
Properties from a firm of independent petroleum engineers acceptable to Bank
prepared in accordance with customary standards and procedures of the petroleum
industry), (ii) title opinions, satisfactory to Bank for those additional
Mineral Interests referred to in (B) above, and (iii) executed mortgage
instruments, satisfactory in form and substance to Bank and its counsel,
mortgaging such additional Mineral Interests to Bank. Within forty-five (45)
days after the receipt of such reports Bank shall determine the Borrowing Base
for the Determination Date and the amount of the automatic monthly reductions
and give written notice thereof to Borrower. Bank's determination of the
Borrowing Base and the amount of the automatic monthly reductions shall be in
Bank's sole discretion, according to its customary engineering practices, based
on Bank's independent appraisal of the loan value of proved, developed,
producing oil and gas properties comprising the Mortgaged Properties taking into
account, among other things, Borrower's contingent liabilities arising in
connection with any pending litigation.

                  (c)      Special Determination of Borrowing Base.

                           In addition to the determinations of the Borrowing
Base required pursuant to Section 2.2(b) hereof, special determinations thereof
may be made at the option of Bank if it in good faith believes that events have
occurred and conditions exist that could decrease the then current Borrowing
Base, and may at any time be requested by Borrower if it, in good faith, (i)
believes that events have occurred or conditions exist that could increase the
then current Borrowing Base or (ii) desires to mortgage additional Mineral
Interests to increase the Borrowing Base. Upon any special determination of the
Borrowing Base, if requested by Bank, Borrower shall submit both (i) a current
report of a firm of independent petroleum engineers acceptable to Bank, prepared
in accordance with customary standards and procedures of the petroleum industry
which report shall (A) evaluate the Mineral Interests subject to such special
redetermination (in the same manner as provided in Section 2.2(b)) and (B) be
dated within sixty (60) days of such requested special redetermination, and,
(ii) title opinions, acceptable to Bank, for those additional Mineral Interests
which Borrower desires to be considered within the Borrowing Base. Adjustments
to the Borrowing Base based upon the addition of Mineral Interests shall not be
effective prior to the date of filing and recording of such Collateral Documents
as required by Bank.

                  (d)      Borrowing Base Deficiency.

                           If at any time the sum of the principal outstanding
as a Revolving Credit Loan plus the Letter of Credit Exposure exceeds the then
effective Borrowing Base, Borrower shall, within ten (10) days after receipt by
Borrower of demand from Bank, pay to Bank the sum equal to the amount of such
excess so that the sum of the principal outstanding as a Revolving Credit Loan
plus the Letter of Credit Exposure after such payment is not in excess of the
then effective Borrowing Base.

         2.3      MANNER OF BORROWING.

                  The amount and date of each Advance shall be designated by the
Borrower's execution of a Notice of Borrowing to be received by Bank, with
respect to Contract Rate Loans, not later than 10:00 a.m. Dallas time one (1)
Business Day prior to, and, with respect to LIBOR Rate Loans, not later than
10:00 a.m. Dallas time three (3) Business Days prior to, the date of such
requested Advance (which Notice of Borrowing shall be sent as provided in
Section 10.3 hereof, and shall be irrevocable and effective upon receipt by
Bank), except the initial Advance. Each such notice shall be deemed to
constitute a representation and warranty by Borrower that the representations
and warranties set forth in Article VI hereof are true and correct on and as of
the date of such notice, with the same force and effect as if made on and as of
such date, and that no Event of Default or condition, event or act which with
the giving of notice or lapse of time, or both, would constitute an Event of
Default, exists and is continuing at such date. Each Advance requested to be
made by Bank hereunder shall be in the aggregate principal amount of $100,000.00
or any higher integral multiple thereof, except that any requested Advance which
would exhaust the Commitment may be made in an amount of the unused portion of
the Commitment.

         2.4      USE OF PROCEEDS.

                  The proceeds of the Revolving Credit Loan shall be used for
Borrower's working capital and general corporate purposes; provided, however,
every dollar advanced in excess of an aggregate $15,000,000 outstanding shall be
used only for the acquisition of producing Mineral Interests.

         2.5      COMMITMENT FEE.

         During the Availability Period, Borrower shall pay to the Bank a
commitment fee determined at the rate of three-eighths percent (.375%) per annum
(computed on the basis of the actual number of days elapsed in a year consisting
of 365 or, if appropriate, 366 days), on the average daily unused portion of the
Commitment (the Letter of Credit Exposure shall be considered a used portion of
the Commitment). Such commitment fee shall accrue from and after the first day
of the Availability Period and shall be payable in quarterly installments on the
last Business Day of each December, March, June and September during the term
hereof, commencing December 31, 1998, and on the Commitment Termination Date.
Borrower and Bank acknowledge and agree that the commitment fees payable
hereunder are bona fide commitment fees and are intended as reasonable
compensation


                                        4

<PAGE>   9



to Bank for committing to make funds available to Borrower as described herein
and for no other purpose.

         2.6      TERMINATION OR REDUCTION OF COMMITMENT.

                  Borrower shall have the right, at any time and from time to
time, upon not less than five (5) Business Days' prior written notice to Bank
(which notice shall be irrevocable and effective upon receipt), to terminate or
permanently reduce (in whole or in part) the unborrowed portions of the
Commitment; provided that each partial reduction of the Commitment shall be in
the aggregate of at least $100,000; and provided further, that any such
reduction shall be accompanied by the payment in full of any commitment fee then
accrued on the amount of such reduction.

         2.7      LETTER OF CREDIT FACILITY.

                  Bank will, from time to time, upon request by Borrower, issue
Letters of Credit provided that (i) Letter of Credit Exposure at the time
(including the amount of the requested Letter of Credit) does not exceed
$1,000,000, (ii) Borrower would be entitled to an Advance under Section 2.1 in
the amount of the requested Letter of Credit, (iii) any Letter of Credit issued
hereunder shall have an expiration date no later than one year from issuance and
on or earlier than ten (10) calendar days prior to the Commitment Termination
Date and (iv) Borrower pays an issuance fee of the greater of (a) one percent of
the face amount of the requested Letter of Credit or (b) $500 and such other
clerical fees as Bank customarily charges to its customers for issuance of a
letter of credit. Borrower shall execute and deliver Bank's customary Letter of
Credit application for each Letter of Credit, and each Letter of Credit shall be
issued in form satisfactory to Bank. If any Letter of Credit is presented for
payment by the beneficiary thereof, Bank shall be entitled to cause an Advance
as a Revolving Credit Loan to be made to reimburse Bank for the payment under
such Letter of Credit, whether or not Borrower would be entitled to an Advance
for such amount pursuant to Section 2.1.

                                   ARTICLE III
                           THE NOTE AND NOTE PAYMENTS

         3.1      REVOLVING CREDIT NOTE.

                  The Revolving Credit Loan made by Bank hereunder shall be
evidenced by a Revolving Credit Note (the "Note") of Borrower, which shall (a)
be dated the date hereof, (b) be in the amount of $50,000,000.00, (c) be payable
to the order of Bank at its principal office as provided in Sections 3.2 and
3.4, (d) bear interest in accordance with Section 3.3 hereof, and (e) be in the
form of Exhibit 3.1 attached hereto with blanks appropriately completed in
conformity herewith.



                                        5

<PAGE>   10



         3.2      PAYMENT OF PRINCIPAL OF THE NOTE.

                  Borrower shall pay the unpaid principal balance of the
Revolving Credit Loan on the Commitment Termination Date and shall make such
other principal payments as may be required by Section 2.2(d).

         3.3      PAYMENT OF INTEREST ON THE NOTE.

                  (a) Contract Rate. The unpaid principal balance of the Note
outstanding from time to time shall bear interest at a fluctuating rate per
annum from day to day equal to the lesser of (i) the Maximum Rate or (ii) the
Contract Rate (subject to the provisions of Section 3.3(b) below).

                  (b) LIBOR Option. The Interest Option shall be exercisable by
Borrower, only in the manner provided below and subject to the conditions and
limitations set forth herein, to designate a portion of the unpaid principal
balance of the Note as a LIBOR Rate Loan:

                           (i)      On the date hereof, Borrower shall give Bank
written notice (an "Interest Notice") specifying the initial Interest Option(s)
and the respective initial amounts of the Contract Rate Loan and the LIBOR Rate
Loan or LIBOR Rate Loans designated by Borrower; provided, no LIBOR Rate Loan
designated by Borrower for any Interest Period shall be less than $500,000.00.
If the required Interest Notice shall not have been timely received by Bank or
fails to designate all or a portion of the unpaid principal amount hereof as
either a Contract Rate Loan or a LIBOR Rate Loan in accordance with the terms
and provisions of this Agreement, Borrower shall be deemed conclusively to have
designated such amounts to be a Contract Rate Loan and to have given Bank notice
of such designation.

                           (ii) By 10:00 a.m. Dallas time on the date at least
three (3) Business Days prior to the termination of any Interest Period for a
LIBOR Rate Loan, Borrower shall give Bank an Interest Notice specifying the
Interest Option which is to be applicable to such LIBOR Rate Loan upon the
expiration of such Interest Period. If the required Interest Notice shall not
have been received by Bank by the time specified in the immediately preceding
sentence, Borrower shall be deemed conclusively to have continued such LIBOR
Rate Loan for a comparable Interest Period immediately upon the expiration of
such Interest Period and to have given Bank notice of such continuation.

                           (iii) Borrower shall have the right, exercisable on
any Business Day, to convert an eligible portion of the Contract Rate Loan to a
LIBOR Rate Loan by giving Bank an Interest Notice of such designation at least
three (3) Business Days prior to the effective date of such exercise; provided,
however, the minimum amount of any LIBOR Rate Loan shall be $500,000.
Additionally, upon termination of any Interest Period, Borrower shall have the
right to convert all or a portion of such principal amount from a LIBOR Rate
Loan to a Contract Rate


                                        6

<PAGE>   11



Loan by giving Bank an Interest Notice of such election at least three (3)
Business Days prior to the effective date of such exercise.

                           (iv)     Borrower may not exercise an Interest Option
if the last day of the Interest Period for such LIBOR Rate Loan would be after
the Commitment Termination Date.

                           (v)      Notwithstanding any provision to the 
contrary contained herein, there shall not exist or be outstanding at any time
more than four LIBOR Tranches. For purposes of this Section 3.3(b)(v), LIBOR
Tranches having different Interest Periods, regardless of whether such LIBOR
Rate Loans commence on the same date, shall be considered separate LIBOR
Tranches.

                  (c)      Limitation on Fluctuating Rate.

                           Notwithstanding the foregoing, if at any time the
Applicable Rate on a given Type of Loan exceeds the Maximum Rate, and,
therefore, the rate of interest on such Loan is limited to the Maximum Rate,
then any subsequent reductions in the Applicable Rate shall not reduce the rate
of interest on such Loan below the Maximum Rate until the total amount of
interest accrued on such Loan equals the amount of interest which would have
accrued thereon if the Applicable Rate had at all times been in effect.

                  (d)      Change in Rate; Past Due Amounts; Calculations of
Interest.

                           Each change in the Contract Rate under the Note shall
become effective without prior written notice to Borrower automatically as of
the opening of business of Bank on the date of each change in the Base Rate.
Interest shall be calculated on the bases of actual days elapsed in a year
consisting of 365 or, if appropriate, 366 days. If any principal of, or interest
on, the Note is not paid when due, then (in lieu of the interest rate provided
in Section 3.3(a)(i) above) such past due principal and interest on the Note
shall bear interest at a rate equal to the Default Rate.

                  (e)      Interest Payment Dates.

                           Interest on the Note shall be due and payable monthly
as it accrues, on the last Business Day of each calendar month during the term
of the Note, and on the date the Availability Period terminates; provided,
however, with respect to any LIBOR Rate Loan, interest shall be payable on the
last day of the applicable Interest Period unless such Interest Period is longer
than three months in which case interest shall be payable on each day which is
three months or a whole multiple thereof after the first day of such Interest
Period and on the last day of such Interest Period.

                  (f)      Illegality. If the adoption of any applicable law,
rule or regulation, or any change therein, or any change in the interpretation
or administration thereof by any governmental authority, central bank or
comparable agency charged with the interpretation or administration thereof, or
compliance by Bank with any request or directive (whether or not having the
force of



                                        7

<PAGE>   12



law) of any such authority, central bank or comparable agency shall make it
unlawful or impractical Bank to make or maintain a LIBOR Rate Loan, Bank shall
so notify Borrower and any then-existing LIBOR Rate Loan of Bank shall
automatically convert to a Contract Rate Loan either (i) on the last day of the
then-current Interest Period applicable to such LIBOR Rate Loan, if Bank may
lawfully continue to maintain and fund such LIBOR Rate Loan to such day, or (ii)
immediately, if Bank may not lawfully continue to maintain such LIBOR Rate Loan
to such day.

                  (g) Requirements of Law. If either (i) the adoption of any
applicable law, rule or regulation, or any change therein, or any change in the
interpretation or administration thereof by any governmental authority, central
bank or comparable agency charged with the interpretation or administration
thereof, or compliance by Bank, with any request or directive (whether or not
having the force of law) of any such authority, central bank or comparable
agency shall subject Bank to any tax (including without limitation any United
States interest equalization or similar tax, however named), duty or other
charge with respect to any LIBOR Rate Loan, this Agreement or Bank's obligation
to compute interest on the principal balance of a Note at a rate based upon the
LIBOR Based Rate, or shall change the basis of taxation of payments to Bank of
the principal of or interest on any LIBOR Rate Loan or any other amounts due
under its Note in respect of any LIBOR Rate Loan or Bank's obligation to compute
the interest on the balance of its Note at a rate based upon the LIBOR Based
Rate, or (ii) any governmental authority, central bank or other comparable
authority shall at any time impose, modify or deem applicable any reserve
(including, without limitation, any imposed by the Board of Governors of the
Federal Reserve System), special deposit or similar requirement against assets
of, deposits with or for the account of, or credit extended by, Bank, or shall
impose on Bank (or its eurodollar lending office) or any relevant interbank
eurodollar market any other condition affecting any LIBOR Rate Loan, the Note or
Bank's obligation to compute the interest on the balance of its Note at a rate
based upon the LIBOR Based Rate; and the result of any of the foregoing is to
increase the cost to Bank of maintaining any LIBOR Rate Loan, or to reduce the
amount of any sum received or receivable by Bank under the Note by an amount
deemed by Bank to be material, then upon demand by Bank, Borrower shall pay to
Bank such additional amount or amounts as will compensate Bank for such
increased cost or reduction. Bank will promptly notify Borrower of any event of
which it has knowledge, occurring after the date hereof, which will entitle Bank
to compensation pursuant to this paragraph. A certificate of Bank claiming
compensation under this paragraph and setting forth the calculation of such
additional amount or amounts to be paid to Bank hereunder shall be presumed
correct in the absence of manifest error.

                  (h) Breakage Costs. Borrower may not repay any LIBOR Rate Loan
or convert all or any portion of a LIBOR Rate Loan to a Contract Rate Loan prior
to the expiration of the applicable Interest Period, unless (i) such repayment
or conversion is specifically required by the terms of the Note, (ii) Bank
demands that such repayment or conversion be made, or (iii) Bank, in its sole
discretion, consents to such repayment or conversion. If for any reason any
LIBOR Rate Loan is repaid or converted prior to the expiration of the
corresponding Interest Period, Borrower shall pay to Bank on demand any amounts
required to compensate Bank for any losses, reasonable costs or expenses which
it may incur as a result of such repayment or conversion. A certificate of


                                        8

<PAGE>   13



Bank claiming compensation under this paragraph and setting forth the
calculation of any additional amount or amounts to be paid to Bank hereunder
shall be presumed correct in the absence of manifest error.

                  (i) Taxes. (1) All payments made by the Borrower under this
Agreement and the Note shall be made free and clear of, and without deduction or
withholding for or on account of, any present or future income, stamp or other
taxes, levies, imposts, duties, charges, fees, deductions or withholdings, now
or hereafter imposed, levied, collected, withheld or assessed by any
Governmental Authority, excluding net income taxes, franchise taxes (imposed in
lieu of net income taxes) and doing business taxes imposed on Bank as a result
of a present or former connection between Bank and the jurisdiction of the
Governmental Authority imposing such tax or any political subdivision or taxing
authority thereof or therein (other than any such connection arising solely from
Bank having executed, delivered or performed its obligations or received a
payment under, or enforced, this Agreement or the Note). If any such
non-excluded taxes, levies, imposts, duties, charges, fees, deductions or
withholdings ("Non-Excluded Taxes") are required to be withheld from any amounts
payable to Bank hereunder or under the Note, the amounts so payable to Bank
shall be increased to the extent necessary to yield to Bank (after payment of
all Non-Excluded Taxes) interest or any such other amounts payable hereunder at
the rates or in the amounts specified in this Agreement, provided, however, that
Borrower shall not be required to increase any such amounts payable to any
Non-U.S. Lender if such Non-U.S. Lender fails to comply with the requirements of
paragraph (2) of this subsection. Whenever any Non-Excluded Taxes are payable by
Borrower, as promptly as possible thereafter, Borrower shall send to Bank a
certified copy of an original official receipt received by Borrower showing
payment thereof. If, when Borrower is required by this Section 3.3(i)(1) to pay
any Non-Excluded Taxes, Borrower fails to pay any Non-Excluded Taxes when due to
the appropriate taxing authority or fails to remit to Bank the required receipts
or other required documentary evidence, Borrower shall indemnify Bank for any
incremental taxes, interest or penalties that may become payable by Bank as a
result of any such failure. The agreements in this subsection shall survive the
termination of this Agreement and the payment of the Obligations and all other
amounts payable hereunder.

                             (2) Any Transferee that is not a citizen or
resident of the United States of America, a corporation, partnership or other
entity created or organized in or under the laws of the United States of
America, or any estate or trust that is subject to federal income taxation
regardless of the source of its income (a "Non-U.S. Lender") shall deliver to
the Borrower and Bank two copies of either U.S. Internal Revenue Service Form
1001 or Form 4224, or, in the case of a Non-U.S. Lender claiming exemption from
U.S. federal withholding tax under Section 871(h) or 881(c) of the Code with
respect to payments of "portfolio interest," a Form W-8, or any subsequent
versions thereof or successors thereto (and, if such Non-U.S. Lender delivers a
Form W-8, an annual certificate representing that such Non-U.S. Lender (i) is
not a"bank" for purposes of Section 881(c) of the Code (and is not subject to
regulatory or other legal requirements as a bank in any jurisdiction, and has
not been treated as a bank in any filing with or submission made to any
Governmental Authority or rating agency), (ii) is not a 10%



                                        9

shareholder (within the meaning of Section 871(h)(3)(B) of the Code) of Borrower
and (iii) is not a controlled foreign corporation related to Borrower (within
the meaning of Section 864(d)(4) of the Code)), properly completed and duly
executed by such Non-U.S. Lender claiming complete exemption from U.S. federal
withholding tax on all payments by Borrower under this Agreement and the other
Loan Documents, along with such other additional forms as the Borrower or Bank
may reasonably request to establish the availability of such exemption. Such
forms shall be delivered by each Non-U.S. Lender on or before the date it
becomes a party to this Agreement (or, in the case of any Participant, on or
before the date such Participant purchases the related participation). In
addition, and provided that such Non-U.S. Lender is legally able to do so, each
Non-U.S. Lender shall deliver such forms promptly upon the obsolescence or
invalidity of any form previously delivered by such Non-U.S. Lender. Each
Non-U.S. Lender shall promptly notify Borrower at any time it determines that it
is no longer in a position to provide any previously delivered certificate to
Borrower (or any other form of certification adopted by the U.S. taxing
authorities for such purpose).

                           (3) If any Transferee shall become aware that it is
entitled to receive a refund in respect of Non-Excluded Taxes paid by Borrower,
or as to which it has been indemnified by Borrower, which refund in the good
faith judgment of such Transferee is allocable to such payment made pursuant to
this Section 3.3(i), it shall promptly notify Borrower of the availability of
such refund and shall, within 30 days after the receipt of a request by
Borrower, apply for such refund. If any Transferee receives a refund in respect
of any Non-Excluded Taxes paid by Borrower, or as to which it has been
indemnified by Borrower, which refund in good faith judgment of such Transferee
is allocable to such payment made pursuant to this Section 3.3(i), it shall
promptly notify Borrower of such refund and shall, within 15 days after receipt,
repay such refund to Borrower net of all out-of-pocket expenses of such
Transferee; provided, however, that Borrower, upon the request of such
Transferee, agrees to repay the amount paid over to Borrower (plus penalties,
interest or other charges) to such Transferee in the event such Transferee is
required to repay such refund to such Governmental Authority. The agreements in
this Section 3.3(i) shall survive the termination of this Agreement and the
payment of the Obligations and all other amounts payable hereunder.

         3.4      PAYMENTS ON THE NOTE.

                  All payments of principal of, and interest on, the Note shall
be made by Borrower to Bank before 11:00 a.m. (Dallas time) in federal or other
immediately available funds at Bank's principal banking office in Dallas, Texas.
Funds received after 11:00 a.m. (Dallas time) shall be treated for all purposes
as having been received by Bank on the first Business Day next following receipt
of such funds. All payments made on the Note shall be credited, to the extent of
amount thereof, in the following manner: (a) first, against all due but unpaid
costs, expenses and other fees (including attorneys' fees) arising under the
terms hereof, (b) second, against the amount of interest accrued and unpaid on
the Note as of the date of such payment, (c) third, against all principal due
and owing on the Note as of the date of such payment, and (d) fourth, to all
other amounts constituting a portion of the Obligations.

         3.5      PREPAYMENTS.

                  Borrower shall have the right, without premium or penalty, at
any time and from time to time, upon one (1) Business Day's prior notice to Bank
with respect to Contract Rate Loans and three (3) Business Days' prior notice to
Bank with respect to LIBOR Rate Loans, to prepay the aggregate principal amount
of the Note in whole or in part; provided that (a) any partial prepayment must
be at least $100,000.00 or an integral multiple thereof, (b) any prepayment
shall be accompanied by the payment of the interest accrued on the amount being
prepaid to the date of payment and (c) Borrower shall be liable for all breakage
costs, if any, as provided in Section 3.3(h).


                                   ARTICLE IV
                                    SECURITY

         4.1      LIENS AND SECURITY INTEREST.

                  To secure performance by Borrower of the payment of the Note
and the Obligations, Borrower shall grant to Bank a first, prior security
interest and lien in all of Borrower's Mineral Interests described in Exhibit
4.1 attached hereto and the oil, gas and mineral production therefrom or
attributable thereto, and in all operating agreements and oil or gas purchase
contracts (now existing or hereafter arising) relating to Borrower's Mineral
Interests and in related personal properties, fixtures and other properties,
pursuant to mortgages, deeds of trust, assignments of production, security
agreements, financing statements and other documents satisfactory to Bank (said
documents and any documents and instruments from time to time amending or
supplementing the same are herein sometimes collectively called the "Collateral
Documents"). Borrower's Mineral Interests and all related personal properties
and rights to payments or proceeds thereon or therefrom, and all other
properties in which Borrower, now or hereinafter, grants or purports to grant to
Bank a security interest or lien in accordance with this Article IV in order to
secure the Note and the Obligations, are hereinafter collectively called the
"Mortgaged Properties."

         4.2      COLLATERAL ACCOUNT.

                  In order to secure further the performance by Borrower of the
Obligations and to effect and facilitate Bank's right of offset, immediately
following Bank's request, Borrower shall execute such forms, authorizations,
documents and instruments, and do such other things, as Bank shall request, in
order to require that pipeline companies, operators of the Mortgaged Properties
and others (collectively, the "Purchasers") purchasing (or acting as agents for,
or making payments on behalf of, those purchasing) the oil, gas and other
minerals produced or to be produced from, or relating to, the Borrower's Mineral
Interests deliver to a post office box number specified by Bank all royalties,
production payments, checks, cash, proceeds and monies now or hereafter payable
by


                                       11

<PAGE>   16


the Purchasers (or any of them) on account of oil, gas or other minerals
produced from or relating to the Borrower's Mineral Interests or otherwise with
respect to the Borrower's Mineral Interest. Bank shall not deliver such
instruments or take other action to collect from the Purchasers until an Event
of Default occurs. Borrower agrees that after an Event of Default all such
royalties, payments and monies delivered to such post office box shall be
deposited by Bank in a cash collateral account at Bank styled "Remington
Production Account." After an Event of Default, Borrower shall, upon receipt,
deposit in the Remington Production Account all such royalties, payments and
monies which Borrower receives directly from the Purchasers. Borrower hereby
irrevocably authorizes and directs Bank to charge from time to time the
Remington Production Account and any other accounts of Borrower at Bank for
amounts due to the Bank hereunder, under the Note and all reimbursement
obligations with respect to Letters of Credit. Bank is hereby authorized, in its
own name or the name of the Borrower, at any time after an Event of Default, to
notify any or all parties obligated to Borrower with respect to the Borrower's
Mineral Interests to make all payments due or to become due thereon directly to
the Bank, or such other person or officer as Bank may require whereupon the
power and authority of the Borrower to collect the same in the ordinary course
of its business shall be deemed to be immediately revoked and terminated. With
or without such general notification after an Event of Default, Bank may take or
bring in Borrower's name or that of the Bank all steps, actions, suits or
proceedings deemed by the Bank necessary or desirable to effect possession or
collection of payments, may complete any contract or agreement of the Borrower
in any way related to any of the Borrower's Mineral Interests, may make
allowances or adjustments related to the Borrower's Mineral Interests, may
compromise any claims related to the Borrower's Mineral Interests or may issue
credit in its own name or the name of the Borrower. Regardless of any provision
hereof, however, Bank shall never be liable for its failure to collect or for
its failure to exercise diligence in the collection, possession, or any
transaction concerning, all or part of the Borrower's Mineral Interests or sums
due or paid thereon, nor shall it or they be under any obligation whatsoever to
anyone by virtue of its security interests and liens relating to the Mortgaged
Properties.

                  Issuance by the Bank of a receipt to any Person obligated to
pay any amounts to Borrower shall be a full and complete release, discharge and
acquittance to such Person to the extent of any amount so paid to the Bank. The
Bank is hereby authorized and empowered on behalf of the Borrower to endorse the
name of the Borrower upon any check, draft, instrument, receipt, instruction or
other document or items, including, but not limited to, all items evidencing
payment upon any indebtedness of any Person to the Borrower coming into the
Bank's possession, and to receive and apply the proceeds therefrom in accordance
with the terms hereof. The Bank is hereby granted an irrevocable Power of
Attorney, which is coupled with an interest, to execute all checks, drafts,
receipts, instruments, instructions or other documents, agreements or items on
behalf of the Borrower, either before or after demand of payment on the Note, as
shall be deemed by the Bank to be necessary or advisable, in the sole discretion
of the Bank, to protect its security interests and liens in the Borrower's
Mineral Interests or the repayment of the Obligations, and the Bank shall not
incur any liability in connection with or arising from its exercise of such
Power of Attorney.

<PAGE>   17



                  The application by Bank of such funds shall, unless Bank shall
agree otherwise in writing, be first to the payment of costs and expenses due
Bank under this Loan Agreement, second to the payment of accrued interest due on
the Note and last to the payment of the principal of the Note and reimbursement
obligations relating to any Letters of Credit. Borrower acknowledges that all
funds so transferred into the Remington Production Account shall be the property
of Borrower only and not subject to any claim by any party other than Bank.

         4.3      BANK OFFSET.

                  In addition to the rights granted to the Bank under Section
4.2 hereof, Borrower hereby grants to Bank a right of offset, to secure
repayment of the Obligations, upon any and all monies, securities or other
property of Borrower and the proceeds therefrom, now or hereafter held or
received by or in transit to Bank, from or for the account of Borrower, whether
for safekeeping, custody, pledge, transmission, collection or otherwise, and
also upon any and all deposits (general or specified) and credits of Borrower,
and any and all claims of Borrower against Bank at any time existing, provided,
however, that Bank's right of offset set forth in this Section 4.3 shall,
without limitation, cover and include account no. 43-01-100-0109802 maintained
by Bank under the terms of that certain Custody Agreement dated January 21,
1994, executed by and between Borrower and Bank. Bank is hereby authorized at
any time and from time to time, without notice to Borrower, to offset,
appropriate, apply and enforce such right of offset against any and all items
hereinabove referred to against the Obligations. Borrower shall be deemed
directly indebteded to Bank in the full amount of the Obligations, and Bank
shall be entitled to exercise the rights of offset provided for above.

         4.4      AGREEMENT TO DELIVER ADDITIONAL COLLATERAL DOCUMENTS.

                  Borrower shall deliver such deeds of trust, mortgages,
security agreements, financing statements, assignments and other collateral
documents (including title opinions and other title assurances) (all of which
shall be deemed part of the "Collateral Documents"), in form and substance
satisfactory to Bank, as Bank may reasonably request from time to time for the
purpose of granting to, or maintaining or perfecting in favor of Bank, mortgage
liens and security interests in any of the Mortgaged Properties, together with
other assurances of the enforceability and priority of Bank's liens and
assurances of due recording and documentation of the Collateral Documents, as
Bank may reasonably require to avoid material impairment of the liens and
security interests granted or purported to be granted pursuant to this Article
IV.

                                   ARTICLE VI
                         REPRESENTATIONS AND WARRANTIES

         To induce Bank to make the Revolving Credit Loan hereunder, Borrower
represents and warrants to Bank that:

         6.1      ORGANIZATION AND GOOD STANDING.

                  Borrower is a corporation duly organized and existing in good
standing under the laws of the State of Delaware, is duly qualified as a foreign
corporation and in good standing in Texas, Mississippi and Louisiana and all
other states in which it is doing business and has the



                                       16

<PAGE>   21



corporate power and authority to own its properties and assets and to transact
the business in which it is engaged and is or will be qualified in those states
wherein it proposes to transact business in the future.

         6.2      AUTHORIZATION AND POWER.

                  Borrower has the corporate power and requisite authority to
execute, deliver and perform this Loan Agreement, the Note and the other Loan
Documents to be executed by Borrower; Borrower is duly authorized to, and has
taken all corporate action necessary to authorize Borrower to, execute, deliver
and perform this Loan Agreement, the Note and such other Loan Documents and is
and will continue to be duly authorized to perform this Loan Agreement, the Note
and such other Loan Documents.

         6.3      NO CONFLICTS OR CONSENTS.

                  Neither the execution and delivery of this Loan Agreement, the
Note or the other Loan Documents, nor the consummation of any of the
transactions herein or therein contemplated, nor compliance with the terms and
provisions hereof or with the terms and provisions thereof, will contravene or
materially conflict with any provision of law, statue or regulation to which
Borrower is subject or any judgment, license, order or permit applicable to
Borrower, or any indenture, mortgage, deed of trust, oil and gas lease,
operating agreement, or other agreement or instrument to which Borrower is a
party or by which Borrower may be bound, or to which Borrower may be subject, or
violate any provision of the Certificate of Incorporation or Bylaws of Borrower.
No consent, approval, authorization or order of any court or governmental
authority or third party is required in connection with the execution and
delivery by Borrower of the Loan Documents or to consummate the transactions
contemplated hereby or thereby.

         6.4      ENFORCEABLE OBLIGATIONS.

         This Loan Agreement, the Note and the other Loan Documents are the
legal and binding obligations of Borrower, enforceable in accordance with their
respective terms, except as limited by bankruptcy, insolvency or other laws of
general application relating to the enforcement of creditors' rights.

         6.5      PRIORITY OF LIENS.

                  As of the date hereof, Bank shall have valid, enforceable,
perfected, first priority liens in the Mortgaged Properties, subject only to the
Permitted Liens.

         6.6      NO LIENS.

                  Except for Permitted Liens, all of the properties and assets
of Borrower (including without limitation the Mineral Interests) are free and
clear of all mortgages, liens, encumbrances and



                                       17

<PAGE>   22



other adverse claims of any nature, and Borrower has and will have good and
marketable title to such properties and assets.

         6.7      FINANCIAL CONDITION.

                  Borrower has delivered to Bank copies of the balance sheet of
Borrower as of December 31, 1997, and the related statements of income, changes
in stockholders' equity, and cash flows for the year ended on such date, audited
by Arthur Andersen LLP, independent certified public accountants; such financial
statements are true and correct, fairly present the financial condition of
Borrower as of such date and have been prepared in accordance with Generally
Accepted Accounting Principles applied on a basis consistent with that of prior
periods; as of the date hereof, there are no obligations, liabilities or
indebtedness (including contingent and indirect liabilities and obligations or
unusual forward or long-term commitments) of Borrower which are (separately or
in the aggregate) material and are not reflected in such financial statements;
no changes having a Material Adverse Effect have occurred in the financial
condition or business of Borrower since December 31, 1997.

         6.8      FULL DISCLOSURE.

                  There is no material fact that Borrower has not disclosed to
Bank which could have a Material Adverse Effect on the properties (including the
Mineral Interests), business, prospects or condition (financial or otherwise) of
Borrower. Neither the financial statements referred in Section 6.7 hereof, nor
any certificate or statement delivered herewith or heretofore by Borrower to
Bank in connection with negotiations of this Loan Agreement, contains any untrue
statement of a material fact or omits to state any material fact necessary to
keep the statements contained herein or therein from being misleading.

against Borrower that would, if adversely determined, have a Material Adverse
Effect on Borrower's financial condition, business or properties.

         6.12     LEASES.

                  The leases which underlie or constitute part of the Mineral

requested reports (prepared by independent petroleum engineers), which have been
obtained by Borrower and concern the estimated oil and gas reserves and future
net revenues attributable to the Mineral Interests. The statements of fact
contained in said reports with respect to the character and ownership of the
Mineral Interests (including, without limitation, the revenue interest and
working interest of Borrower stated therein) and the other factual data
furnished by Borrower as a basis for the estimates set forth therein are true
and correct and do not omit any material fact necessary to make said statements
not misleading.

as used herein, meaning the right to explore for, drill and produce oil, gas or

marketing of oil, gas and other minerals borne by Borrower with respect to each
respective property.

         6.15     NET REVENUE INTEREST.

                  Borrower owns a "net revenue interest" in each of the

term "net revenue interest," as used herein, meaning the proportionate share of
the production of oil, gas or other minerals to which Borrower is entitled after
deduction of all royalties, overriding royalties and other interests payable
from or measured by production.

         6.16     BURDENSOME CONTRACTS.

                  Borrower is not a party to, or bound by, any contract which in

INDEMNITEE HEREUNDER FOR ANY LEGAL OR OTHER EXPENSE SUBSEQUENTLY INCURRED BY
SUCH INDEMNITEE IN CONNECTION WITH THE DEFENSE THEREOF OTHER THAN REASONABLE

                  10.5     INVALID PROVISIONS.

                           If any provision of this Loan Agreement is held to be
illegal, invalid, or unenforceable under present or future laws effective during
the term of this Loan Agreement, such provision shall be fully severable and
this Loan Agreement shall be construed and enforced as if such illegal, invalid
or unenforceable provision had never comprised a part of this Loan Agreement,
and the remaining provisions of this Loan Agreement shall remain in full force
and effect and shall not be affected by the illegal, invalid or unenforceable
provision or by its severance from this Loan Agreement, unless such continued
effectiveness of this Loan Agreement, as modified, would be contrary to the
basic understandings and intentions of the parties as expressed herein. If any
provision of this Loan Agreement shall conflict with or be inconsistent with any
provision of any of the other Loan Documents, then the terms, conditions and
provisions of this Loan Agreement shall prevail.

                  10.6     INTEREST RATE.

                           Regardless of any provisions contained in this Loan
Agreement, the Note or in any of the other Loan Documents, Bank shall never be
deemed to have contracted for or be entitled to receive, collect or apply as
interest on the Note, any amount in excess of the maximum rate of interest
permitted to be charged by applicable law, and, in the event that Bank ever
receives, collects or applies as interest any such excess, such amount which
would be excessive interest shall be applied to the reduction of the unpaid
principal balance of the Note, and, if the principal balance of the Note is paid
in full, any remaining excess shall forthwith be paid to Borrower. In
determining whether or not the interest paid or payable under any specific
contingency exceeds the highest lawful rate, Borrower and Bank shall, to the
maximum extent permitted under applicable law, (i) characterize any
non-principal payment (other than payments which are expressly designated as
interest payments hereunder) as an expense, fee, or premium, rather than as
interest, (ii) exclude voluntary prepayments and the effect thereof, and (iii)
spread the total amount of interest throughout the entire contemplated term of
the Note so that the interest rate is uniform throughout such term.

                  10.7     PARTIES BOUND; ASSIGNMENT.

                           (a)      The provisions of this Loan Agreement shall
be binding upon and inure to the benefit of the parties hereto and their
respective successors and assigns, except Borrower may neither assign nor
otherwise transfer any of its rights or obligations under this Loan Agreement
without the prior written consent of Bank.

                           (b)      Bank may at any time grant to one or more 
banks or other institutions (each a "Participant") a participating interest in
the Commitment or any or all of the Revolving Credit Loan. In the event of any
such grant by Bank of a participating interest to a Participant, Bank shall
remain responsible for the performance of its obligations hereunder, and
Borrower shall remain responsible for the performance of its obligations
hereunder, and Borrower shall continue to deal solely and directly with Bank in
connection with Bank's rights and obligations under this Loan


                                       39

<PAGE>   44



Agreement. Any agreement pursuant to which Bank may grant such a participating
interest shall provide that Bank shall retain the sole right and responsibility
to enforce the Obligations hereunder including, without limitation, the right to
approve any amendment, modification or waiver of any provision of this Loan
Agreement. An assignment or other transfer which is not permitted by subsection
(c) below shall be given effect for purposes of this Loan Agreement only to the
extent of a participating interest granted in accordance with this subsection
(b).

                           (c)      Bank may at any time assign to one or more 
lending institutions (each an "Assignee") all or a proportionate part of all, of
its rights and obligations under this Loan Agreement and the Note, and such
Assignee shall assume such rights and obligations, pursuant to an Assignment and
Acceptance Agreement; provided, however, that the foregoing shall not be
applicable in the case of, and this subsection (c) shall not restrict, an
assignment or other transfer by Bank to an Affiliate of Bank. Upon execution and
delivery of such Assignment and Acceptance Agreement and payment by such
Assignee to Bank of an amount equal to the purchase price agreed between Bank
and such Assignee, such Assignee shall be a Lender party to this Loan Agreement
and shall have all the rights and obligations of the Bank with a Commitment as
set forth in such Assignment and Acceptance Agreement, and the Bank shall be
released from its obligations hereunder to a corresponding extent, and no
further consent or action by any party shall be required. Upon the consummation
of any assignment pursuant to this subsection (c), the Bank, and Borrower shall
make appropriate arrangements so that, if required, a new Note is issued to such
Assignee and Bank.

                           (d)      Bank shall maintain at its principal offices
in Dallas, Texas or at such other location as the Bank shall designate in
writing to Borrower, a copy of each Assignment and Acceptance Agreement
delivered to and accepted by it and a register for the recordation of the names
and addresses of the Assignees, the amount of each Assignees' Pro Rata
Percentage and its Commitment, and the name and address of each Assignee's agent
for service of process (the "Register"). The entries in the Register shall be
conclusive and binding for all purposes, absent manifest error, and Borrower and
the Bank may treat each person or entity whose name is recorded in the Register
as a Lender hereunder for all purposes of this Loan Agreement. The Register
shall be available for inspection and copying by Borrower during normal business
hours upon reasonable prior notice to the Bank. Upon receipt of any Assignment
and Acceptance Agreement, Bank shall, if such Assignment and Acceptance
Agreement has been completed and fully-executed (i) accept such an Assignment
and Acceptance Agreement, (ii) record the information contained therein in the
Register, and (iii) give prompt notice thereof to Borrower.

                  10.8     HEADINGS.

                           Section headings are for convenience of reference
only and shall in no way affect the interpretation of this Loan Agreement.

Business Days prior to the first day of such Interest Period. In the event that

principal balance from the date of the initial advance under the Loan Agreement
until maturity at the varying rates per annum and on the dates, as determined in
accordance with the provisions of Section 3.3 of the Loan Agreement. Payments of
both principal and interest herein shall be made to Payee at its principal
office in Dallas, Texas, in lawful money of the United States of America and in
immediately available funds.

         This Fifth Renewal and Extension Revolving Credit Note has been
executed and delivered pursuant to, and is subject to certain terms and
conditions set forth in that certain Amended and Restated Secured Revolving
Credit Loan Agreement (as the same may be amended, modified or restated from
time to time, the "Loan Agreement") by and between Maker and Payee, dated as of
the date hereof and is the "Note" referred to therein. This Note is secured by
certain Collateral Documents covering certain Mineral Interests of Borrower.
Reference is hereby made to the Loan Agreement for: (i) a statement of the
rights and obligations of Maker; (ii) a statement of the events upon which the
maturity of this Note may be accelerated; and (iii) the rights of Payee upon the
occurrence of an Event of Default.

         Capitalized terms not otherwise defined herein shall have the meaning 
respectively assigned to them in the Loan Agreement, unless the context hereof 
otherwise requires or provides.

         If this Note is placed in the hands of an attorney for collection, or
if it is collected through any legal proceedings, at law or in equity, or in
bankruptcy, receivership or other court proceedings, Maker agrees to pay all
costs of collection, including but not limited to court costs and reasonable
attorneys' fees.

         Maker and each surety, endorser, guarantor and any other party now or
hereafter liable for payment of any sums of money payable on this Note, jointly
and severally waive presentment and demand for payment, protest, notice of
protest and nonpayment, notice of intent to accelerate, notice of acceleration
and all other notices, filing of suit and diligence in collecting this Note or
enforcing any security with respect to same, and agree that their liability
under this Note shall not be affected by any renewal or extension in the time of
payment hereof, or in any indulgences, or by any release, substitution or change
in any security for the payment of this Note, and hereby consent to any and all
renewals, extensions, indulgences, releases or changes, regardless of the number
of such renewals, extensions, indulgences, releases or changes.

         Any provision herein, or in the Loan Agreement, or any other document
executed in connection herewith, or in any other agreement or commitment,
whether written or oral, express or implied, to the contrary notwithstanding,
neither Payee nor any holder hereof shall in any event be entitled to receive or
collect, nor shall or may amounts received hereunder be credited, so that Payee
or any holder hereof shall have collected or be paid, as interest, a sum greater
than the Maximum Rate. If any construction of this Note or the Loan Agreement,
or any and all other papers, agreements or commitments, indicates a different
right given to Payee or any holder hereof to ask for, demand or receive any
larger sum as interest, such is a mistake in calculation or wording, which this
clause shall override and control, it being the intention of the parties that
this Note, the Loan Agreement and all other instruments securing the payment of
this Note shall in all things comply with applicable law and proper adjustments
shall automatically be made accordingly. In the event that Payee or any holder
hereof ever receives, collects or applies as interest any sum in excess of the
Maximum Rate, such excess amount shall be applied to the reduction of the unpaid
principal balance of this Note and if this Note is paid in full, any remaining
excess shall be paid to Maker. In determining whether or not the interest paid
or payable, under any specific contingency, exceeds the Maximum Rate, Maker and
Payee or any holder hereof shall, to the maximum extent permitted by applicable
law (a) characterize any non-principal payment as an expense or fee rather than
as interest, (b) exclude voluntary prepayments and the effects thereof, and (c)
"spread" the total amount of interest throughout the entire term of this Note;
provided, that if this Note is paid and performed in full prior to the end of
the full contemplated term thereof, and if the interest received for the actual
period of existence hereof exceeds the Maximum Rate, Payee or any holder hereof
shall refund to the Maker the amount of such excess or credit the amount of such
excess against the aggregate unpaid principal balance of all Loans made by the
Payee or any holder hereof under this Note at the time in question. To the
extent federal law permits Payee to contract for, charge or receive a greater
amount of interest, Payee will rely on federal law instead of the Texas Finance
Code, as supplemented by Texas Credit Title, for the purpose of determining the
Maximum Rate. Additionally, to the maximum extent permitted by applicable law
now or hereafter in effect, Payee may, at its option and from time to time,
implement any other method of computing the Maximum Rate under the Texas Finance
Code, as supplemented by Texas Credit Title, or under other applicable law, by
giving notice, if required, to Maker as provided by applicable law now or
hereafter in effect. Notwithstanding anything to the contrary contained herein
or in any of the other Loan Documents, it is not the intention of Payee to
accelerate the maturity of any interest that has not accrued at the time of such
acceleration or to collect unearned interest at the time of such acceleration.

         In no event shall Chapter 346 of the Texas Finance Code (which
regulates certain revolving loan accounts and revolving tri-party accounts)
apply to this note. To the extent that Chapter 303 of the Texas Finance Code is
applicable to this note, the "weekly ceiling" specified in such Chapter 303 is
the applicable ceiling; provided that, if any applicable law permits greater
interest, the law permitting the greatest interest shall apply.

         This Note has been prepared, is being executed and delivered, and is to
be performed in the State of Texas, and the substantive laws of such state and
the applicable federal laws of the United States of America shall govern the
validity, construction, enforcement and interpretation of this Note.

         All Advances made by Payee to Maker pursuant to the Loan Agreement and
all payments

of the principal thereof shall be noted by Payee on the schedule attached
hereto, or on a continuation of such schedule attached hereto; provided,
however, that the failure of Payee to make any such notation shall not limit or
otherwise affect the obligations of Maker hereunder or under the Loan Agreement.

         This Note is given in renewal, extension and increase of, but not in
extinguishment of, that certain Fourth Renewal and Extension Revolving Credit
Note in the original principal amount of $25,000,000.00 dated as of June 1, 
1998 from Borrower to Payee (the "Prior Note"). The execution of this Note is 
not intended to and shall not cause or result in a novation with regard to the 
indebtedness evidenced by the Prior Note.
