              OFFER TO EXCHANGE ITS 11 5/8% SENIOR NOTES DUE 2003
    
   
                      WHICH HAVE BEEN REGISTERED UNDER THE
    
   
                   SECURITIES ACT OF 1933 FOR ANY AND ALL OF
    
   
                 ITS OUTSTANDING 11 5/8% SENIOR NOTES DUE 2003
    
 
   
THE EXCHANGE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT 5:00 P.M., NEW YORK CITY
TIME, ON AUGUST 23, 1996, UNLESS EXTENDED.
    
 
   
Benton Oil and Gas Company, a Delaware corporation (the "Company"), hereby
offers, upon the terms and subject to the conditions set forth in this
Prospectus (as the same may be amended or supplemented from time to time, the
"Prospectus") and the accompanying Letter of Transmittal (which together
constitute the "Exchange Offer"), to exchange up to $125 million aggregate
principal amount of its 11 5/8% Senior Notes due 2003 (the "New Notes"),
pursuant to a Registration Statement (as defined herein) of which this
Prospectus constitutes a part, for a like principal amount of its outstanding
11 5/8% Senior Notes due 2003 (the "Old Notes"), issued on May 2, 1996, of which
$125 million aggregate principal amount is outstanding.
    
 
   
The terms of the New Notes are identical in all material respects to the terms
of the Old Notes, except that (i) the New Notes have been registered under the
Securities Act of 1933, as amended (the "Securities Act") and therefore will not
be subject to certain restrictions on transfer applicable to the Old Notes, will
not contain certain legends relating thereto and will not be entitled to
registration rights, and (ii) the New Notes will not provide for any increase in
the interest rate thereon. In that regard, the Old Notes provide that if (i) a
registration statement relating to the Exchange Offer is not filed with the
Securities and Exchange Commission on or prior to July 1, 1996, (ii) the
registration statement for the Exchange Offer is not declared effective on or
prior to July 31, 1996, or (iii) the Exchange Offer is not consummated or a
registration statement with respect to resale of the Old Notes is not declared
effective on or prior to August 30, 1996, then additional interest (in addition
to the interest otherwise due on the Old Notes) will accrue at an annual rate of
0.50% on the Old Notes from May 1, 1996. See "Description of the Old Notes." The
New Notes are being offered for exchange in order to satisfy certain obligations
of the Company under the Registration Rights Agreement dated as of May 2, 1996
(the "Registration Rights Agreement") between the Company and the Initial
Purchaser (as defined herein) of the Old Notes. The New Notes will be issued
under the same Indenture (as defined herein) as the Old Notes and the New Notes
and the Old Notes will constitute a single series of debt securities under the
Indenture. In the event that the Exchange Offer is consummated, any Old Notes
which remain outstanding after consummation of the Exchange Offer and the New
Notes issued in the Exchange Offer will vote together as a single class for
purposes of determining whether holders of the requisite percentage in
outstanding principal amount of Notes (as defined herein) have taken certain
actions or exercise certain rights under the Indenture. The New Notes and the
Old Notes are collectively referred to herein as the "Notes" See "Description of
the New Notes" and "Description of the Old Notes."
    
 
Interest on the New Notes is payable semi-annually on May 1 and November 1 of
each year, (each, an "Interest Payment Date"), commencing on the first such date
following the original issuance date of the New Notes. The New Notes will mature
on May 1, 2003. The New Notes are not entitled to any sinking fund. The New
Notes will be redeemable at the option of the Company, in whole or in part, at
any time on or after May 1, 2000, at the redemption prices set forth herein,
together with accrued and unpaid interest to the redemption date. The Company
may also redeem at its option at any time prior to May 1, 1999 up to 25% of the
aggregate principal amount of the Notes then outstanding with the proceeds of
one or more public offerings of certain equity securities at a redemption price
equal to 111.625% of the principal amount of such Notes, plus accrued and unpaid
interest to the redemption date; provided that at least $93.75 million in
aggregate principal amount of Notes remains outstanding immediately after giving
effect to such redemption.
 
   
The New Notes will be senior unsecured obligations of the Company and will rank
senior in right of payment to all existing and future Subordinated Indebtedness
(as defined) and pari passu with all other Senior Indebtedness (as defined) of
the Company. The New Notes will be effectively subordinated to all liabilities
of the Company's subsidiaries and all secured indebtedness of the Company.

SEE "RISK FACTORS" BEGINNING ON PAGE 16 FOR A DISCUSSION OF CERTAIN RISK FACTORS
THAT SHOULD BE CONSIDERED BY HOLDERS PRIOR TO TENDERING THEIR OLD NOTES IN THE
EXCHANGE OFFER.
    
 
   
THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE SECURITIES
AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE
ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A
CRIMINAL OFFENSE.
    
 
   
                 The date of this Prospectus is July 12, 1996.

At March 31, 1996, $37.2 million of consolidated indebtedness and trade payables
would have been liabilities of the Company's subsidiaries or secured
indebtedness of the Company and ranked effectively senior to the Notes and the
Company would have had $6.4 million of outstanding indebtedness and trade
payables that would have ranked pari passu with the Notes. See "Capitalization"
and "Description of the New Notes -Ranking."
    
 
The Company is making the Exchange Offer in reliance on the position of the
staff of the Division of Corporation Finance of the Securities and Exchange
Commission (the "Commission") as set forth in certain interpretive letters
addressed to third parties in other transactions. However, the Company has not
sought its own interpretive letter and there can be no assurance that the staff
of the Division of Corporation Finance of the Commission would make a similar
determination with respect to the Exchange Offer as it has in such interpretive
letters to third parties. Based on these interpretations by the staff of the
Division of Corporation Finance, and subject to the two immediately following
sentences, the Company believes that the New Notes issued pursuant to this
Exchange Offer in exchange for Old Notes may be offered for resale, resold and
otherwise transferred by a holder thereof (other than a holder who is a
broker-dealer) without further compliance with the registration and prospectus
delivery requirements of the Securities Act, provided that such New Notes are
acquired in the ordinary course of such holder's business and that such holder
is not participating, and has no arrangement or understanding with any person to
participate, in a distribution (within the meaning of the Securities Act) of
such New Notes. However, any holder of Old Notes who is an "affiliate" of the
Company or who intends to participate in the Exchange Offer for the purpose of
distributing New Notes, or any broker-dealer who purchased Old Notes from the
Company to resell pursuant to Rule 144A under the Securities Act ("Rule 144A")
or any other available exemption under the Securities Act, (a) will not be able
to rely on the interpretations of the staff of the Division of Corporation
Finance of the Commission set forth in the above-mentioned interpretive letters,
(b) will not be permitted or entitled to tender such Old Notes in the Exchange
Offer and (c) must comply with the registration and prospectus delivery
requirements of the Securities Act in connection with any sale or other transfer
of such Old Notes unless such sale is made pursuant to an exemption from such
requirements. In addition, as described below, if any broker-dealer holds Old
Notes acquired for its own account as a result of market-making or other trading
activities and exchanges such Old Notes for New Notes, then such broker-dealer
must deliver a prospectus meeting the requirements of the Securities Act in
connection with any resales of such New Notes.
 
   
Each holder of Old Notes who wishes to exchange Old Notes for New Notes in the
Exchange Offer will be required to represent that (i) it is not an "affiliate"
of the Company, (ii) any New Notes to be received by it are being acquired in
the ordinary course of its business, (iii) it has no arrangement or
understanding with any person to participate in a distribution (within the
meaning of the Securities Act) of such New Notes, and (iv) if such holder is not
a broker-dealer, such holder is not engaged in, and does not intend to engage
in, a distribution (within the meaning of the Securities Act) of such New Notes.
Each broker-dealer that receives New Notes for its own account pursuant to the
Exchange Offer must acknowledge that it acquired the Old Notes for its own
account as the result of market-making activities or other trading activities
and must agree that it will deliver a prospectus meeting the requirements of the
Securities Act in connection with any resale of such New Notes. The Letter of
Transmittal states that by so acknowledging and by delivering a prospectus, a
broker-dealer will not be deemed to admit that it is an "underwriter" within the
meaning of the Securities Act. Based on the position taken by the staff of the
Division of Corporation Finance of the Commission in the interpretive letters
referred to above, the Company believes that broker-dealers who acquired Old
Notes for their own accounts, as a result of market-making activities or other
trading activities ("Participating Broker-Dealers") may fulfill their prospectus
delivery requirements with respect to the New Notes received upon exchange of
such Old Notes (other than Old Notes which represent an unsold allotment from
the original sale of the Old Notes) with a prospectus meeting the requirements
of the Securities Act, which may be the prospectus prepared for an exchange
offer so long as it contains a description of the plan of distribution with
respect to the resale of such New Notes. Accordingly, this Prospectus, as it may
be amended or supplemented from time to time, may be used by a Participating
Broker-Dealer during the period referred to below in connection with resales of
New Notes received in exchange for Old Notes where such Old Notes were acquired
by such Participating Broker-Dealer for its own account as a result of
market-making or other trading activities. Subject to certain provisions set
forth in the Registration Rights Agreement, the Company has agreed that this
Prospectus, as it may be amended or supplemented from time to time, may be used
by a Participating Broker-Dealer in connection with resales of such New Notes
for a period ending 180 days after the Expiration Date referred to below
(subject to extension under certain limited circumstances described below) or,
if earlier, when all such New Notes have been disposed of by such Participating
Broker-Dealer. See "Plan of Distribution." Any Participating Broker-Dealer who
is an "affiliate" of the Company may not rely on such interpretive letters and
must comply with the registration and prospectus delivery requirements of the
Securities Act in connection with any resale transaction. See "The Exchange
Offer -- Resales of New Notes."
    
 
   
In that regard, each Participating Broker-Dealer who surrenders Old Notes
pursuant to the Exchange Offer will be deemed to have agreed, by execution of
the Letter of Transmittal, that, upon receipt of notice from the Company of the
occurrence of any event or the discovery of any fact which makes any statement
contained or incorporated by reference in this Prospectus untrue in any material
respect or which causes this Prospectus to omit to state a material fact
necessary in order to make the statements contained or incorporated by reference
herein, in light of the circumstances under which they were made, not misleading
or of the occurrence of certain other events specified in the Registration
Rights Agreement, such Participating Broker-Dealer will suspend the sale of
    
 
                                        2
<PAGE>   3
 
   
(Cover page continued)
    
 
   
New Notes pursuant to this Prospectus until the Company has amended or
supplemented this Prospectus to correct such misstatement or omission and has
furnished copies of the amended or supplemented Prospectus to such Participating
Broker-Dealer or the Company has given notice that the sale of the New Notes may
be resumed, as the case may be. If the Company gives such notice to suspend the
sale of the New Notes, it shall extend the 180-day period referred to above
during which Participating Broker-Dealers are entitled to use this Prospectus in
connection with the resale of New Notes by the number of days during the period
from and including the date of the giving of such notice to and including the
date when Participating Broker-Dealers shall have received copies of the amended
or supplemented Prospectus necessary to permit resales of the New Notes or to
and including the date on which the Company has given notice that the sale of
New Notes may be resumed, as the case may be.
    
 
   
The New Notes will be a new issue of securities for which there currently is no
market. Although the Initial Purchaser has informed the Company that it
currently intends to make a market in the New Notes, it is not obligated to do
so, and any such market making may be discontinued at any time without notice.
Accordingly, there can be no assurance as to the development or liquidity of any
market for the New Notes. The Company currently does not intend to apply for
listing of the New Notes on any securities exchange or for quotation through the
National Association of Securities Dealers Automated Quotation System.
    
 
   
Any Old Notes not tendered and accepted in the Exchange Offer will remain
outstanding and will be entitled to all the same rights and will be subject to
the same limitations applicable thereto under the Indenture (except for those
rights which terminate upon consummation of the Exchange Offer). Following
consummation of the Exchange Offer, the holders of Old Notes will continue to be
subject to the existing restrictions upon transfer thereof and the Company will
have no further obligation to such holders to provide for registration under the
Securities Act of the Old Notes held by them. To the extent that Old Notes are
tendered and accepted in the Exchange Offer, a holder's ability to sell
untendered Old Notes could be adversely affected. See "Summary -- Certain
Consequences of a Failure to Exchange Old Notes."
    
 
THIS PROSPECTUS AND THE RELATED LETTER OF TRANSMITTAL CONTAIN IMPORTANT
INFORMATION. HOLDERS OF OLD NOTES ARE URGED TO READ THIS PROSPECTUS AND THE
RELATED LETTER OF TRANSMITTAL CAREFULLY BEFORE DECIDING WHETHER TO TENDER THEIR
OLD NOTES PURSUANT TO THE EXCHANGE OFFER.
 
   
Old Notes may be tendered for exchange on or prior to 5:00 p.m., New York City
time, on August 23, 1996 (such time on such date being hereinafter called the
"Expiration Date"), unless the Exchange Offer is extended by the Company (in
which case the term "Expiration Date" shall mean the latest date and time to
which the Exchange Offer is extended). Tenders of Old Notes may be withdrawn at
any time on or prior to the Expiration Date. The Exchange Offer is not
conditioned upon any minimum principal amount of Old Notes being tendered for
exchange. However, the Exchange Offer is subject to certain events and
conditions which may be waived by the Company and to the terms and provisions of
the Registration Rights Agreement. Old Notes may be tendered in whole or in part
in a principal amount of $1,000 and integral multiples thereof. The Company has
agreed to pay all expenses of the Exchange Offer. See "The Exchange
Offer -- Fees and Expenses." Each New Note will bear interest from the most
recent date to which interest has been paid or duly provided for on the Old Note
surrendered in exchange for such New Note or, if no such interest has been paid
or duly provided for on such Old Note, from May 1, 1996. Holders of the Old
Notes whose Old Notes are accepted for exchange will not receive accrued
interest on such Old Notes for any period from and after the last Interest
Payment Date to which interest has been paid or duly provided for on such Old
Notes prior to the original issue date of the New Notes or, if no such interest
has been paid or duly provided for, will not receive any accrued interest on
such Old Notes, and will be deemed to have waived the right to receive any
interest on such Old Notes accrued from and after such Interest Payment Date or,
if no such interest has been paid or duly provided for, from and after May 1,
1996.
    
 
   
Any waiver, extension or termination of the Exchange Offer will be publicly
announced by the Company through a release to the Dow Jones News Service and as
otherwise required by applicable law or regulations.
    
 
   
This Prospectus, together with the Letter of Transmittal, is being sent to all
registered holders of Old Notes as of July 23, 1996.
    
 
The Company will not receive any cash proceeds from the issuance of the New
Notes offered hereby. No dealer-manager is being used in connection with this
Exchange Offer. See "Use of Proceeds" and "Plan of Distribution."

                                    SUMMARY
    
 
   
The following summary information is qualified in its entirety by the more
detailed information and financial statements appearing elsewhere, or
incorporated by reference, in this Prospectus. Unless the context requires
otherwise, "Benton" or the "Company" refers to Benton Oil and Gas Company and
its subsidiaries. Capitalized terms in this summary under the caption "The
Exchange Offer" and "The New Notes" and not otherwise defined are defined under
the caption "Description of the New Notes -- Certain Definitions." See
"Glossary" for the definition of certain oil and gas terms used herein.
    
 
                                  THE COMPANY
GENERAL
 
Benton Oil and Gas Company is an independent energy company which has been
engaged in the development and production of oil and gas properties since 1989.
Although originally active only in the United States, the Company has developed
significant interests in Venezuela and Russia, and recently sold substantially
all of its remaining United States oil and gas interests. The Company's
operations are conducted principally through its 80%-owned Venezuelan
subsidiary, Benton-Vinccler, C.A. ("Benton-Vinccler"), which operates in the
South Monagas Unit in Venezuela, and its 34%-owned Russian joint venture,
GEOILBENT, which operates in the North Gubkinskoye Field in Siberia, Russia.
 
   
As of December 31, 1995, the Company had total assets of $214.8 million ($234.9
million at March 31, 1996), total estimated proved reserves of 96,212 MBOE, and
a standardized measure of discounted future net cash flow, before income taxes,
for total proved reserves of $372.3 million. For the year ended December 31,
1995 and the three months ended March 31, 1996, the Company had total revenues
of $65.1 million and $32.9 million, respectively and net income of $10.6 million
and $6.3 million, respectively.
    
 
The Company has been successful in increasing reserves, production, revenues and
earnings during the last two years. From year-end 1993 through 1995, estimated
proved reserves increased from 42,785 MBOE to 96,212 MBOE, and net production
increased from a total of 519 MBOE in 1993 to 6,647 MBOE in 1995. As production
has increased over this period, average lifting costs per Bbl have declined from
$7.26 to $1.19 in Venezuela, and from $16.22 to $5.63 in Russia. Between 1993
and 1995, the Company's annual revenues increased from $7.5 million to $65.1
million. During the same period, the Company's EBITDA (as defined in the
Indenture) increased from $0.5 million to $32.4 million. See "--Summary
Consolidated Financial Information."
 
The following table summarizes the Company's financial operating data, proved
reserves and production activity in Venezuela and Russia for each of the three
years ended December 31:

(1) Includes 100% of the reserve information, production activity and financial
    data, without deduction for minority interest. All Venezuelan reserves are
    attributable to an operating service agreement between Benton-Vinccler and
    Lagoven, S.A. ("Lagoven") an affiliate of the national oil company,
    Petroleos de Venezuela, S.A. ("PdVSA"), under which all mineral rights are
    owned by the Government of Venezuela. See "Business -- South Monagas Unit,
    Venezuela" and "-- Reserves."
 
   
(2) The Company's Russian operations are conducted through GEOILBENT, which is
    only 34%-owned by the Company and, consequently, does not qualify as a
    Restricted Subsidiary as defined in the Indenture. Accordingly, for purposes
    of the Indenture, the Company's Russian operations will be excluded from the
    calculation of covenants and Oil and Gas Reserve Estimate, as defined. See
    "Description of the New Notes -- Certain Covenants."
    
 
(3) The financial information related to Russia and included in the 1995
    presentation contains information for the nine months ended September 30,
    1995, the end of the fiscal period for GEOILBENT. See Note 15 to the
    Company's Consolidated Financial Statements.
 
(4) Expenses include lease operating costs and production taxes and depletion.

BUSINESS STRATEGY
 
The Company's business strategy is to identify and exploit new oil and gas
reserves in under-developed areas while seeking to minimize the associated risk
of such activities. Specifically, the Company endeavors to minimize risk by
employing the following strategies in its business activities: (i) seek new
reserves in areas of low geologic risk; (ii) use proven advanced technology in
both exploration and development to maximize recovery; (iii) establish a local
presence through joint venture partners and the use of local personnel; (iv)
commit capital in a phased manner to limit total commitments at any one time;
and (v) reduce foreign exchange risks through receipt of revenues in U.S.
currency.
 
- - SEEK NEW RESERVES IN AREAS OF LOW GEOLOGIC RISK. The Company has had
significant success in identifying under-developed reserves in the U.S. and
internationally. In particular, the Company has notable experience and expertise
in seeking and developing new reserves in countries where perceived potential
political and operating difficulties have sometimes discouraged other energy
companies from competing. As a result, the Company has established operations in
Venezuela and Russia which have significant reserves that have been acquired and
developed at relatively low costs. The Company is seeking similar opportunities
in other countries and areas which it believes have high potential.
 
- - USE OF PROVEN ADVANCED TECHNOLOGY IN BOTH EXPLORATION AND DEVELOPMENT. The
Company's use of 3-D seismic technology, in which a three dimensional image of
the earth's subsurface is created through the computer interpretation of seismic
data, combined with its experience in designing the seismic surveys and
interpreting and analyzing the resulting data, allow for a more detailed
understanding of the subsurface than do conventional surveys. Such technology
contributes significantly to field appraisal, development and production. The
3-D seismic information, in conjunction with subsurface geologic data from
previously drilled wells, is used by the Company's experienced in-house
technical team to identify previously undetected reserves. The 3-D seismic
information can also be used to guide drilling on a real-time basis, and has
been especially helpful in the horizontal drilling done in Venezuela in order to
take advantage of oil-trapping faults.
 
- - ESTABLISH A LOCAL PRESENCE THROUGH JOINT VENTURE PARTNERS AND THE USE OF LOCAL
PERSONNEL. The Company has sought to establish a local presence where it does
business to facilitate stronger relationships with local government and labor
through joint venture arrangements with local partners. Moreover, the Company
employs almost exclusively local personnel to run foreign operations both to
take advantage of local knowledge and experience and to minimize cost. These
efforts have created an expertise within Company management in forming effective
foreign partnerships and operating abroad. The Company believes that it has
gained access to new development opportunities as a result of its reputation as
a dependable partner.
 
- - COMMIT CAPITAL IN A PHASED MANNER TO LIMIT TOTAL COMMITMENTS AT ANY ONE
TIME. While the Company typically has agreed to a minimum capital expenditure or
development commitment at the outset of new projects, expenditures to fulfill
these commitments are phased over time. In addition, the Company seeks, where
possible, to use internally generated funds for further capital expenditures and
to invest in projects which provide the potential for an early return to the
Company.
 
- - REDUCE FOREIGN EXCHANGE RISKS. The Company seeks to reduce foreign currency
exchange risks by providing for the receipt of revenues by the Company in U.S.
dollars while most operating costs are incurred in local currency. Pursuant to
the operating agreement between the Company's Venezuelan subsidiary and the
state oil company, the operating fees earned by the Company are paid directly to
the Company's bank account in the U.S. in U.S. dollars. GEOILBENT receives
revenues from export sales in U.S. dollars paid to its account in Moscow. As the
Company expands internationally, it will seek to establish similar arrangements
for new operations.
 
THE VENEZUELAN OPERATIONS
 
South Monagas Unit
In July 1992, the Company and Venezolana de Inversiones y Construcciones
Clerico, C.A. ("Vinccler"), a Venezuelan construction and engineering company,
signed a 20-year operating service agreement with Lagoven to reactivate and
further develop the Uracoa, Tucupita and Bombal Fields, which are a part of the
South Monagas Unit. The oil and gas operations are conducted by Benton-Vinccler,
the Company's 80%-owned subsidiary. Under the terms of the operating service
agreement, Benton-Vinccler is a contractor for Lagoven and is responsible for
overall operations of the South Monagas Unit. Benton-Vinccler invoices Lagoven
each quarter based on Bbls of oil accepted by Lagoven during the quarter, using
quarterly adjusted contract service fees per Bbl, and receives payments from
Lagoven in U.S. dollars deposited directly into a U.S. bank account.
 
During March 1996, a total of approximately 50 wells were producing an average
of approximately 31.5 MBbls of oil per day in the Uracoa Field. Since 1992, 14
previously drilled wells have been reactivated and 42 new wells have been
drilled in the Uracoa Field, with 41, or 98%, completed and placed on
production. At December 31, 1995, proved reserves attributable to the Company's
Venezuelan operations were 73,593 MBOE, which represented approximately 76% of
the Company's proved reserves. During 1996, Benton-Vinccler plans to drill
approximately 7 vertical and 26 horizontal wells, 2 injection wells and one
 
                                        6

step-out well adjacent to the Uracoa Field at an anticipated cost of $40-45
million. In addition, Benton-Vinccler intends to expand the capacity of its
production facilities during 1996 at an anticipated cost of $21 million.
 
Before becoming inactive, Tucupita had been substantially developed and
produced; relatively few wells had been drilled at Uracoa and Bombal.
Benton-Vinccler intends to evaluate the potential of the Tucupita Field in 1996
by drilling a pilot oil well. Benton-Vinccler currently plans to reactivate and
develop the Bombal Field beginning in 1998.
 
Delta Centro Block
In January 1996, the Company and its bidding partners, Louisiana Land and
Exploration ("LL&E") and Norcen Energy Company ("Norcen"), were awarded the
right to explore and develop the Delta Centro Block in Venezuela. The Delta
Centro Block consists of approximately 2,100 square kilometers (526,000 acres)
located in the delta of the Orinoco River in the eastern part of Venezuela.
Although no significant exploratory activity has been conducted in the block,
PdVSA has estimated that the area may contain recoverable reserves of as much as
820 MMBbls, and may be capable of producing up to 160 MBbls of oil per day. The
general area of Venezuela in which the Delta Centro Block is located is known to
be a significant source of hydrocarbons, evidenced by the Orinoco tar sands to
the south and the recently discovered El Furrial light oil trend to the north.
 
The contract requires a minimum exploration work program consisting of
completing a 1,300 kilometer seismic survey and drilling three wells to depths
of 12,000 to 18,000 feet within five years. The Company will have a 30% interest
in the exploration venture, with LL&E and Norcen each owning a 35% interest,
with possible subsequent significant participation in development by an
affiliate of PdVSA. See "Business -- Delta Centro Block, Venezuela -- General."
 
THE RUSSIAN OPERATIONS
 
The Company operates in Russia through its 34% interest in the GEOILBENT joint
venture. The Company's partners in this venture are the local exploration
company, Purneftegasgeologia, and the local production company, Purneftegas,
each of which owns a 33% interest. GEOILBENT develops, produces and markets oil
from the North Gubkinskoye Field in the West Siberia region of Russia, located
approximately 2,000 miles northeast of Moscow. Before GEOILBENT commenced its
operations, North Gubkinskoye was one of the largest oil and gas fields in the
region not under commercial production.
 
Production from the field is delivered via the pipeline network owned by
Transneft, the state oil pipeline monopoly, to various points on the western
border of Russia. During 1995, the majority of GEOILBENT's crude sales were made
to purchasers in Germany. All export sales are paid in U.S. dollars directly
into GEOILBENT's account in Moscow. During March 1996, approximately 40 wells
were producing an average of approximately 8.4 MBbls of oil per day.
 
RECENT DEVELOPMENTS
 
   
On April 12, 1996, the Company sold to Shell Offshore Inc. ("Shell")
substantially all of its U.S. properties, including its interests in the West
Cote Blanche Bay, Rabbit Island and Belle Isle Fields in Louisiana, for a
purchase price of $35.4 million, with the sale effective as of December 31, 1995
(the "U.S. Property Sale"). The 1995 and 1996 consolidated financial data set
forth herein includes the results of operations from these properties. See Note
14 to the Company's Consolidated Financial Statements. Because the properties
were held for sale at December 31, 1995, the Company's reserve report excludes
all reserves attributable to these properties.
    
 
On April 22, 1996, the Venezuelan government announced the lifting of controls
on foreign exchange transactions, having announced the lifting of controls on
interest rates one week earlier. The Venezuelan government also announced a $1.4
billion preliminary loan accord with the International Monetary Fund. Although
these actions have led to the devaluation of the bolivar and a rise in interest
rates and are likely to lead to temporary increases in inflation, they are
generally viewed as likely to have a positive effect in the long term. Upon the
announcement, both the Venezuelan stock and bond markets showed strong gains and
it is expected that additional funds will be made available soon by the World
Bank and the Inter-American Development Bank.

                                               Tendering Old Notes -- Guaranteed Delivery."
RESALES OF NEW NOTES.........................  The Company is making the Exchange Offer in reliance
                                               on the position of the staff of the Division of
                                               Corporation Finance of the Commission as set forth in
                                               certain interpretive letters addressed to third
                                               parties in other transactions. However, the Company
                                               has not sought its own interpretive letter and there
                                               can be no assurance that the staff of the Division of
                                               Corporation Finance of the Commission would make a
                                               similar determination with respect to the Exchange
                                               Offer as it has in such interpretive letters to third
                                               parties. Based on these interpretations by the staff
                                               of the Division of Corporation Finance, and subject to
                                               the two immediately following sentences, the Company
                                               believes that New Notes issued pursuant to this
                                               Exchange Offer in exchange for Old Notes may be
                                               offered for resale, resold and otherwise transferred
                                               by a holder thereof (other than a holder who is a
                                               broker-dealer) without further compliance with the
                                               registration and prospectus delivery requirements of
                                               the Securities Act, provided that such New Notes are
                                               acquired in the ordinary course of such holder's
                                               business and that such holder is not participating,
                                               and has no arrangement or understanding with any
                                               person to participate, in a distribution (within the
                                               meaning of the Securities Act) of such New Notes.
                                               However, any holder of Old Notes who is an "affiliate"

                                               receives New Notes for its own account pursuant to the
                                               Exchange Offer must acknowledge that it acquired the

                                               Letter of Transmittal states that by so acknowledging
                                               and by delivering a prospectus, a broker-dealer will
                                               not be deemed to admit that it is an "underwriter"
                                               within the meaning of the Securities Act. Based on the

                                               that at least $93.75 million in aggregate principal

                                               See "Description of the New Notes -- Optional
                                               Redemption."
CHANGE IN CONTROL............................  Upon a Change in Control, each holder of the New Notes
                                               may require the Company to repurchase such holder's
                                               New Notes, in whole or in part, at a purchase price in

RANKING......................................  The New Notes will constitute senior unsecured debt
                                               obligations of the Company and will rank senior in
                                               right of payment to all existing and future
                                               Subordinated Indebtedness and pari passu with all
                                               other Senior Indebtedness. The New Notes will be
                                               effectively subordinated to secured indebtedness of
                                               the Company and all liabilities of the Company's
                                               subsidiaries, except to the extent that the Company is
                                               itself recognized as a creditor to such subsidiary, in
                                               which case the claims of the Company would still be
                                               subordinate to any security interest in the assets of
                                               such subsidiary, and indebtedness of such subsidiary
                                               senior to that held by the Company. At March 31, 1996,
                                               after giving pro forma effect to the U.S. Property
                                               Sale and the issuance of the Old Notes and the use of
                                               proceeds received from each transaction as set forth
                                               in "Capitalization," $37.2 million of consolidated
                                               indebtedness and trade payables would have been
                                               liabilities of the Company's subsidiaries or secured
                                               indebtedness of the Company and ranked effectively
                                               senior to the New Notes and the Company would have had
                                               $6.4 million of outstanding indebtedness and trade
                                               payables that would have ranked pari passu with the
                                               New Notes. In addition, the Company could have
                                               incurred up to $38.0 million of secured indebtedness
                                               under its revolving letter of credit and loan facility
                                               which would have ranked effectively senior to the New
                                               Notes. See "Description of the New Notes -- Ranking."
CERTAIN COVENANTS............................  The Indenture contains certain covenants that, among
                                               other restrictions, limit the ability of the Company
                                               and its Restricted Subsidiaries to incur additional
                                               indebtedness, pay dividends and make certain
                                               investments, engage in transactions with its
                                               affiliates, sell assets, incur or suffer to exist
                                               certain liens securing indebtedness unless the New
                                               Notes are equally and ratably secured, and engage in
                                               mergers and consolidations. The Indenture will also
                                               limit the amount of indebtedness the Company's
                                               Restricted Subsidiaries may assume or the amount of
                                               indebtedness of the Company they may guarantee unless
                                               such Restricted Subsidiaries simultaneously guarantee
                                               the payment of the New Notes. See "Description of the
                                               New Notes -- Certain Covenants."
USE OF PROCEEDS..............................  The Company will receive no proceeds from this
                                               Exchange Offer.
ABSENCE OF MARKET FOR THE NEW NOTES..........  The New Notes will be a new issue of securities for
                                               which there currently is no market. Although J.P.
                                               Morgan Securities Inc., the initial purchaser of the
                                               Old Notes (the "Initial Purchaser"), has informed the
                                               Company that it currently intends to make a market in
                                               the New Notes, it is not obligated to do so, and any
                                               such market making may be discontinued at any time
                                               without notice. Accordingly, there can be no assurance
                                               as to the development or liquidity of any market for
                                               the New Notes. The Company currently does not intend
                                               to apply for listing of the New Notes on any
                                               securities exchange or for quotation through the
                                               National Association of Securities Dealers Automated
                                               Quotation System.

            CERTAIN CONSEQUENCES OF A FAILURE TO EXCHANGE OLD NOTES
    
 
   
The sale of the Old Notes was not registered under the Securities Act or any
state securities laws and therefore the Old Notes may not be offered, sold or
otherwise transferred except in compliance with the registration requirements of
the Securities Act and any other applicable securities laws, or pursuant to an
exemption therefrom or in a transaction not subject thereto, and in each case in
compliance with certain other conditions and restrictions, including the
Company's and the Trustee's right in certain cases to require the delivery of
opinions of counsel, certifications and other information prior to any such
transfer. Old Notes which remain outstanding after consummation of the Exchange
Offer will continue to bear a legend reflecting such restrictions on transfer.
In addition, upon consummation of the Exchange Offer, holders of Old Notes which
remain outstanding will not be entitled to any rights to have the resale of such
Old Notes registered under the Securities Act or to any similar rights under the
Registration Rights Agreement. The Company currently does not intend to register
under the Securities Act the resale of any Old Notes which remain outstanding
after consummation of the Exchange Offer.
    
 
   
To the extent that Old Notes are tendered and accepted in the Exchange Offer, a
holder's ability to sell untendered Old Notes could be adversely affected. In
addition, although the Old Notes are eligible for trading in the Private
Offerings, Resale and Trading through Automatic Linkages ("PORTAL") market, to
the extent that Old Notes are tendered and accepted in connection with the
Exchange Offer, any trading market for Old Notes which remain outstanding after
the Exchange Offer could be adversely affected.
    
 
   
The New Notes and any Old Notes which remain outstanding after consummation of
the Exchange Offer will constitute a single series of debt securities under the
Indenture and, accordingly, will vote together as a single class for purposes of
determining whether holders of the requisite percentage in outstanding principal
amount thereof have taken certain actions or exercised certain rights under the
Indenture. See "Description of the New Notes -- General."
    
 
   
The Old Notes provide that, if the Exchange Offer is not consummated by August
31, 1996, the interest rate borne by the Old Notes will increase by 0.50% per
annum from May 1, 1996 until the Exchange Offer is consummated. See "Description
of the Old Notes." Following consummation of the Exchange Offer, the Old Notes
will not be entitled to any increase in the interest rate thereon. The New Notes
will not be entitled to any such increase in the interest rate thereon.

(1) The financial information related to Russia and included in the year end
    1995 presentation contains information for the nine months ended September
    30, 1995, the end of the fiscal period for GEOILBENT. Similarly, the 1996
    presentation contains information at, and for the three months ended
    December 31, 1995. See Note 15 to the Company's Consolidated Financial
    Statements.
    
 
   
(2) Assuming the U.S. Property Sale had occurred on January 1, 1995, pro forma
    effects on the consolidated statement of operations for the year ended
    December 31, 1995 would include reductions in oil and gas revenues, lease
    operating costs and production taxes, depletion and interest expense of $7.4
    million, $1.0 million, $4.0 million and $2.7 million, respectively. The pro
    forma effects on the consolidated statement of operations for the three
    months ended March 31, 1996 would include reductions in oil and gas
    revenues, lease operating costs and production taxes, depletion and interest
    expense of $4.1 million, $0.2 million, $1.4 million and $0.6 million,
    respectively.
    
 
   
(3) EBITDA has been calculated as defined in the Indenture and has been included
    solely to facilitate consideration of the covenants in the Indenture that
    are based, in part, on EBITDA. See "Description of the New Notes -- Certain
    Definitions." EBITDA is not intended to represent cash flow from operations
    as defined by generally accepted accounting principles ("GAAP") and should
    not be considered as an alternative to net income as an indicator of the
    Company's operating performance or to cash flow as a measure of liquidity.
    
 
   
(4) EBITDA/Interest Ratio has been calculated as defined in the Indenture. See
    "Description of the New Notes -- Certain Definitions."
    
 
   
(5) For purposes of determining the ratio of earnings to fixed charges,
    "earnings" represents income (loss) before income taxes plus fixed charges
    exclusive of capitalized interest, and "fixed charges" consists of interest,
    whether expensed or capitalized, amortization of debt expense and an
    estimated portion of rent expense representing interest costs. As a result
    of the losses incurred by the Company for the year ended December 31, 1993,
    earnings were insufficient to cover fixed charges by $4.8 million. After
    giving effect to the sale of the Old Notes, to the extent proceeds will be
    used to retire presently outstanding indebtedness, the pro forma ratio of
    earnings to fixed charges would have been 2.60 for the year ended December
    31, 1995 and 6.03 for the three months ended March 31, 1996.

(3) The Company values its reserves as of December 31 of each year, based on oil
    and natural gas prices as of that date. Market prices for both oil and
    natural gas are subject to a significant degree of variation both in
    domestic and international markets, and this variation will affect the
    calculation of future net cash flows reported by the Company at any specific
    date.

                                  RISK FACTORS
 
   
Prospective purchasers of the New Notes should read this entire Prospectus
carefully. Ownership of the Notes involves certain risks. In addition to the
other information contained in this Prospectus, investors should carefully
consider the following factors in connection with an investment in the Notes.
    
 
RISKS RELATED TO THE COMPANY
 
Risk from Substantial Concentration of Operations
The Company's cash flow-generating operations are substantially concentrated in
Venezuela. For 1995, the Company derived approximately 78% of its consolidated
oil and gas revenues and approximately 76% of its proved reserves from its
Venezuelan operations. If the Venezuelan operations are adversely effected, the
Company, due to its concentration in and reliance on the Venezuelan operations,
will experience an adverse impact on its financial condition and operations.
There are significant operating and economic risks associated with conducting
business in Venezuela. See "-- Risks Related to the Company -- Political and
Economic Risks of International Operations -- Venezuela."
 
Political and Economic Risks of International Operations -- General
Substantially all of the Company's oil and gas producing operations and
non-financial assets are in Venezuela and Russia and all operating income is
expected to be generated from these countries (absent any new investments). As a
result, the Company is subject to certain political, economic and other
uncertainties including risks of war, civil disturbance, expropriation,
nationalization, renegotiation or modification of existing contracts, taxation
policies, foreign exchange restrictions, international monetary fluctuations and
other hazards arising out of foreign governmental sovereignty over the Company's
operations.
 
Political and Economic Risks of International Operations -- Venezuela
The Company began to operate in Venezuela in 1992. For 1995, the Company derived
approximately 78% of its consolidated oil and gas revenues and approximately 76%
of its proved reserves from its Venezuelan operations. The petroleum industry in
Venezuela is highly regulated by the government with respect to such matters as
maximum daily production, methods of production and environmental matters, both
directly and indirectly through PdVSA. In addition, the timing and extent of the
Company's development activities are subject to the approval of Lagoven and the
Ministry of Energy and Mines. There can be no assurance that the government or
PdVSA will not impose significant new regulations regarding the petroleum
industry generally or that the development activities proposed by
Benton-Vinccler will receive the necessary approval. The Company also expects to
increase its exposure to Venezuela through the continued investment in
Benton-Vinccler and the Delta Centro consortium. While Benton-Vinccler has never
had a material dispute or payment interruption with Lagoven, PdVSA or the
Venezuelan government, the country of Venezuela has experienced significant
political and economic instability, high inflation, and shortages of foreign
currency.
 
Political and Economic Situation. In May 1993, the Venezuelan Senate voted to
authorize the impeachment of President Carlos Andres Perez. Subsequently, Rafael
Caldera was elected president and took office in February 1994. Upon assuming
the presidency, President Caldera was immediately faced with a solvency crisis
in the banking system which necessitated a government takeover of nine financial
institutions, including Banco Latino, one of the largest Venezuelan banks.
Consequently, the bolivar devalued sharply, inflation rose and gross domestic
product ("GDP") contracted. Though Venezuela experienced positive GDP growth for
1995, it was the first increase in three years, and the 1995 GDP figures did not
reflect the full effects of a currency devaluation at year end. Many independent
sources are predicting another GDP contraction in 1996. On April 22, 1996, the
Venezuelan government announced the lifting of controls on foreign exchange
transactions, having announced the lifting of controls on interest rates one
week earlier. The Venezuelan government also announced a $1.4 billion
preliminary loan accord with the International Monetary Fund. Although these
actions have led to the devaluation of the bolivar and a rise in interest rates
and are likely to lead to temporary increases in inflation, they are generally
viewed as likely to have a positive effect in the long term. There can be no
assurance, however, that such actions will be successful in resolving
Venezuela's economic difficulties.
 
Inflation and Currency Controls. Venezuela has experienced high levels of
inflation over the past decade. The consumer price inflation rate was
approximately 38% for calendar year 1993, 61% for 1994, and 60% for 1995. In
addition to increasing the Company's bolivar-denominated expenses with respect
to its Venezuelan operations, these high rates of inflation led the Venezuelan
government to devalue the bolivar by 41% on December 11, 1995. In July 1994, the
Venezuelan government imposed a program of currency exchange controls that was
lifted in April 1996. Pursuant to its agreement with Lagoven, Benton-Vinccler
receives its payments from Lagoven in U.S. dollars deposited directly into a
U.S. bank account. Although the lifting of currency controls is expected to lead
to increased economic stability in the long term, it is likely to lead to a
temporary rise in
 
                                       16
<PAGE>   17
 
inflation in Venezuela. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- Effects of Changing Prices, Foreign
Exchange Rates and Inflation."
 
Oil Production and OPEC. News reports speculate that Venezuela is currently
producing oil in excess of the output quota established by OPEC. While Venezuela
remains a member of OPEC and has yet to face any sanctions, there is a risk that
pressure from OPEC could cause Venezuela to cut oil production voluntarily to
comply with the established quotas or take action that could depress world oil
prices. Such compliance could require a significant reduction in Venezuelan oil
production and could have a material adverse impact on Benton-Vinccler.
 
Political and Economic Risks of International Operations -- Russia
Since the dissolution of the Soviet Union in 1991, Russia has experienced
periods of political unrest and instability, high inflation, wide currency
exchange rate swings, contractions in GDP, volatile tariff and taxation
policies, and the lack of a clear and stable legal and administrative
environment governing oil and gas licensing and operations. There can be no
assurance that any of these factors in addition to other factors may not persist
or worsen and therefore negatively effect the Company's operations in Russia.
 
In addition to the factors discussed above, Russia has established an export
tariff on all oil produced in and exported from Russia which, as imposed, has
the effect of reducing the potential profits to the Company and could render its
proved reserves attributable to Russia uneconomic. Russia has recently announced
that effective in July 1996, oil export tariffs will be terminated in accordance
with an IMF loan condition. However, Russia has proposed that such tariffs be
replaced by an excise, pipeline or other tax on producers which may equal or
exceed the export tariff, but it is unclear how such other tax rates and regimes
will be set and administered. The legislative and regulatory environment in
Russia continues to be subject to frequent change and uncertainty.
 
The Company believes it will not receive any significant distributions from
GEOILBENT for several years because substantially all of the money received by
GEOILBENT from the North Gubkinskoye Field will be reinvested to fund
development activities.
 
Properties Under Development
As of December 31, 1995, approximately 65% of the Company's proved reserves were
undeveloped and required development activities, consisting primarily of
development drilling and construction of production facilities. As a result, the
Company will require substantial capital expenditures to develop all of its
proved reserves. At December 31, 1995, the anticipated future development costs
for proved reserves in Venezuela and Russia were $76.4 million and $36.7
million, respectively. The Company does not currently have the capital to
develop all of these reserves, and if such capital does not otherwise become
available, the Company will either enter into joint ventures to develop the
projects, which will result in the Company retaining a smaller interest, or not
develop the reserves. There can be no certainty regarding the commercial
feasibility of developing these reserves, the availability of financing, or the
timing or costs associated therewith. If such capital is available, there can be
no assurance that the Company will be able to develop and produce sufficient
reserves to recover the costs expended and operate the wells profitably. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Capital Resources and Liquidity."
 
Engineers' Estimates of Reserves and Future Net Revenue
Estimates of economically recoverable oil and gas reserves and of future net
cash flows are based upon a number of variable factors and assumptions, all of
which are to some degree speculative and may vary considerably from actual
results. Therefore, actual production, revenues, taxes, and development and
operating expenditures may not occur as estimated. Future results of operations
of the Company will depend upon its ability to develop, produce and sell its oil
and gas reserves. The reserve data included herein are estimates only and are
subject to many uncertainties. Actual quantities of oil and gas may differ
considerably from the amounts set forth herein. In addition, different reserve
engineers may make different estimates of reserve quantities and cash flows
based upon the same available data. See "Business -- Reserves."
 
Development of Additional Reserves
The Company's future success may also depend upon its ability to find or acquire
additional oil and gas reserves that are economically recoverable. Except to the
extent that the Company conducts successful exploration or development
activities or acquires properties containing proved reserves, the proved
reserves of the Company will generally decline as reserves are produced. There
can be no assurance that the Company will be able to discover additional
commercial quantities of oil and gas, or that the Company will be able to
continue to acquire interests in under-developed oil and gas fields and enhance
production and reserves by drilling replacement wells and drilling development
wells, or that the Company will have continuing success drilling productive
wells and acquiring under-developed properties at low finding costs.
 
                                       17
<PAGE>   18
 
Retention and Attraction of Key Personnel
The Company depends to a large extent on the abilities and continued
participation of certain key employees, the loss of whose services could have a
material adverse effect on the Company's business. In an effort to minimize the
risk, the Company has entered into employment agreements with certain key
employees, and has purchased a $5.0 million key-man life insurance policy on the
life of A.E. Benton. There can be no assurance that the Company will be able to
attract and retain such personnel on acceptable terms and the failure to do so
could have a material adverse effect on the Company.
 
RISKS RELATED TO THE OIL AND GAS INDUSTRY
 
Risk of Oil and Gas Operations
The Company's operations are subject to all of the risks normally incident to
the operation and development of oil and gas properties and the drilling of oil
and gas wells, including encountering unexpected formations or pressures,
blowouts, cratering and fires, and, in horizontal wellbores, the increased risk
of mechanical failure and collapsed holes, the occurrence of any of which could
result in personal injuries, loss of life, environmental damage and other damage
to the properties of the Company or others. In addition, because the Company
acquires interests in under-developed oil and gas fields that have been operated
by others for many years, the Company may be liable for any damage or pollution
caused by any prior operations of such oil and gas fields. In accordance with
customary industry practice, the Company is not fully insured against these
risks, nor are all such risks insurable. Accordingly, there can be no assurance
that such insurance as the Company does maintain will be adequate to cover any
losses or exposure for liability.
 
Current Oil and Gas Industry Conditions
Historically, the markets for oil and natural gas have been volatile and are
likely to continue to be volatile in the future. Prices for oil and natural gas
are subject to wide fluctuation in response to relatively minor changes in
supply of and demand for oil and natural gas, market uncertainty and a variety
of additional factors that are beyond the control of the Company. These factors
include political conditions in the Middle East, the foreign supply of oil and
natural gas, the price of foreign imports, the level of consumer product demand,
weather conditions, domestic and foreign government regulations, the price and
availability of alternative fuels and overall economic conditions. Lower oil
prices also may reduce the amount of the Company's oil that is economic to
produce. In addition, the marketability of the Company's production depends upon
the availability and capacity of gathering systems and pipelines.
 
Government Regulation; Environmental Risks
The Company's business is regulated by certain federal, state, local and foreign
laws and regulations relating to the development, production, marketing and
transmission of oil and gas, as well as environmental and safety matters. There
can be no assurance that laws and regulations enacted in the future will not
adversely affect the Company's exploration for, or the production and marketing
of, oil and gas.
 
Oil and gas operations are subject to extensive foreign, federal, state and
local laws regulating the discharge of materials into the environment or
otherwise relating to the protection of the environment. Numerous governmental
departments issue rules and regulations to implement and enforce such laws which
are often difficult and costly to comply with and which carry substantial
penalties for failure to comply. The regulatory burden on the oil and gas
industry increases its cost of doing business and consequently affects its
profitability. These laws, rules and regulations affect the operations of the
Company. Compliance with environmental requirements generally could have a
material adverse effect upon the capital expenditures, earnings or competitive
position of the Company.
 
Competition
The oil and gas exploration and production business is highly competitive. A
large number of companies and individuals engage in the drilling for oil and
gas, and there is a high degree of competition for desirable oil and gas
properties suitable for drilling and for materials and third-party services
essential for their exploration and development. Many of the Company's
competitors have greater financial and other resources than does the Company.
 
   
RISKS RELATED TO AN INVESTMENT IN THE NOTES
    
 
Substantial Leverage
   
The Company will require substantial cash flow to meet its principal repayment
and interest obligations on the Notes. After giving effect to the sale of the
Old Notes and the U.S. Property Sale as if each had occurred on March 31, 1996,
the Company and its subsidiaries would have had total pro forma indebtedness of
approximately $154.0 million at such date. The Company expects to use a
substantial portion of the proceeds from the sale of the Old Notes for
development activities at its oil and gas properties which the Company
anticipates will increase oil and gas production and cash flow to enable the
Company to repay or refinance
    
 
                                       18

the Notes when due. However, there can be no assurance that expenditure of such
proceeds will result in sufficient increased cash flow to repay or refinance the
Notes when due. In addition, the Indenture will impose significant operating and
financial restrictions on the Company. Such restrictions will affect, and in
many respects limit or prohibit, among other things, the ability of the Company
and its Restricted Subsidiaries to incur additional indebtedness, pay dividends
and make certain investments, engage in transactions with affiliates, sell
assets, incur or suffer to exist certain liens securing indebtedness unless the
Notes are equally and ratably secured, and engage in mergers or consolidations.
The Indenture will also limit the amount of indebtedness the Company's
Restricted Subsidiaries may assume and the amount of indebtedness of the Company
they may guarantee unless such Restricted Subsidiaries simultaneously guarantee
the payment of the Notes. The leveraged position of the Company and the
restrictive covenants contained in the Indenture could significantly limit the
ability of the Company to respond to changing business or economic conditions or
to respond to substantial declines in operating results. See "Description of the
New Notes."
    
 
Liquidity Needs; Ability to Repay Notes
   
The Company may from time to time fund a portion of its working capital needs
and capital expenditure requirements from external financing. In addition, the
Company expects that in order to repay the principal amount of the Notes or to
purchase the Notes upon the occurrence of a Change in Control, it may be
required to seek additional financing or engage in asset sales or in similar
transactions. There can be no assurance that sufficient funds for any of the
foregoing purposes would be available to the Company at the time they were
required. See "Description of the New Notes."
    
 
Holding Company Structure
   
The New Notes will be and the Old Notes are obligations exclusively of the
Company. Because the Company's operations are conducted almost entirely through
its subsidiaries, the cash flow and the consequent ability of the Company to
service its debt, including the Notes, are dependent upon the earnings of the
Company's subsidiaries and the distribution of those earnings to the Company.
The subsidiaries are separate and distinct legal entities and have no
obligation, contingent or otherwise, to pay any amounts due pursuant to the
Notes or to make funds available therefore, whether by dividends, loans or other
payments. In addition, the payment of dividends and the making of loans and
advances to the Company by its subsidiaries may be subject to statutory or
contractual restrictions and are contingent upon the earnings of those
subsidiaries and subject to various business considerations. Currently, the
Company only has one operating subsidiary, Benton-Vinccler, that may be expected
to make funds available to the Company to pay any amounts due pursuant to the
Notes.
    
 
   
Lack of a Public Market for the New Notes
    
   
The New Notes will be a new issue of securities, and the Company does not intend
to list them on any securities exchange. If the New Notes are traded after their
initial issuance, they may trade at a discount from their initial offering price
depending upon prevailing interest rates, the market for similar securities and
other factors. J. P. Morgan Securities Inc. has informed the Company that it
currently intends to make a market in the New Notes. However, it is not
obligated to do so, and any such market making may be discontinued at any time
without notice. See "Plan of Distribution." There can be no assurance that an
active trading market for the New Notes will develop. See "Description of the
New Notes."

                                USE OF PROCEEDS
 
   
The Company will not receive any cash proceeds from the issuance of the New
Notes offered hereby. In consideration for issuing the New Notes in exchange for
Old Notes as described in this Prospectus, the Company will receive Old Notes in
like principal amount. The Old Notes surrendered in exchange for the New Notes
will be retired and cancelled. Accordingly, the issuance of the New Notes will
not result in any change in the indebtedness of the Company.
    
 
   
The net proceeds to the Company from the sale of the Old Notes was approximately
$120.8 million. The Company has used or intends to use such net proceeds: (i) to
prepay in full the $20.0 million aggregate principal amount of its outstanding
13% Senior Notes due 2007 and accrued interest thereon, with a prepayment
premium of approximately $7.4 million; (ii) to repay approximately $6.5 million
in trade financings; and (iii) for general corporate purposes, including the
Company's ongoing exploration and development programs. See "Business -- South
Monagas Unit, Venezuela -- Drilling and Development Activity," "-- Delta Centro
Block, Venezuela -- Drilling and Development Activity" and "-- North

                      SELECTED CONSOLIDATED FINANCIAL DATA
 
   
The following selected consolidated financial data for the Company for each of
the five years in the period ended December 31, 1995, are derived from the
Company's audited consolidated financial statements. The selected consolidated
financial data for the three months ended March 31, 1995 and 1996 are derived
from the Company's unaudited consolidated financial statements. In the opinion
of management, such unaudited consolidated financial statements contain all
adjustments (consisting of only normal recurring accruals) necessary for a fair
presentation of the consolidated financial condition and results of operations
as of and for the periods presented. Operating results for the three months
ended March 31, 1996 are not necessarily indicative of the results that may be
expected for the entire fiscal year ending December 31, 1996. The consolidated

- ---------------
 
(1) For the year ended December 31, 1991 the Company recorded income tax expense
    of $174,000 and an extraordinary item for the utilization of loss
    carryforward for the same amount.
 
   
(2) The financial information related to Russia and included in the year end
    1995 presentation contains information at, and for the nine months ended,
    September 30, 1995, the end of the fiscal period for GEOILBENT. See Note 15
    to the Company's Consolidated Financial Statements. Similarly, the 1996
    presentation contains information at, and for the three months ended
    December 31, 1995.
    
 
   
(3) Assuming the U.S. Property Sale had occurred on January 1, 1995, pro forma
    effects on the consolidated statement of operations for the year ended
    December 31, 1995 would include reductions in oil and gas revenues, lease
    operating costs and production taxes, depletion and interest expense of $7.4
    million, $1.0 million, $4.0 million and $2.7 million respectively. The pro
    forma effects on the consolidated statement of operations for the three
    months ended March, 31, 1996 would include reductions in oil and gas
    revenues, lease operating costs and production taxes, depletion and interest
    expense of $4.1 million, $0.2 million, $1.4 million and $0.6 million,
    respectively.
    
 
   
(4) EBITDA has been calculated as defined in the Indenture and has been included
    solely to facilitate consideration of the covenants in the Indenture that
    are based, in part, on EBITDA. See "Description of the New Notes -- Certain
    Definitions." EBITDA is not intended to represent cash flow from operations
    as defined by generally accepted accounting principles ("GAAP") and should
    not be considered as an alternative to net income as an indicator of the
    Company's operating performance or to cash flow as a measure of liquidity.
    
 
   
(5) EBITDA/Interest Ratio has been calculated as defined in the Indenture. See
    "Description of the New Notes -- Certain Definitions."
    
 
   
(6) For purposes of determining the ratio of earnings to fixed charges,
    "earnings" represents income (loss) before income taxes plus fixed charges
    exclusive of capitalized interest, and "fixed charges" consists of interest,
    whether expensed or capitalized, amortization of debt expense and an
    estimated portion of rent expense representing interest costs. As a result
    of the losses incurred by the Company for the years ended December 31, 1992
    and 1993, earnings were insufficient to cover fixed charges by $2.9 million
    and $4.8 million, respectively. After giving effect to the sale of the Old
    Notes, to the extent proceeds will be used to retire presently outstanding
    indebtedness, the pro forma ratio of earnings to fixed charges would have
    been 2.60 for the year ended December 31, 1995 and 6.03 for the three months
    ended March 31, 1996.
    
 
(7) No cash dividends were paid during the periods presented.

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS
 
GENERAL
 
Principles of Consolidation and Accounting Methods
   
The Company has included the results of operations of Benton-Vinccler in its
consolidated statement of operations since January 1, 1994 and has reflected the
50% ownership interest of Vinccler during January and February 1994 and the 20%
ownership interest of Vinccler subsequent thereto as a minority interest. Prior
to 1994, Benton-Vinccler was proportionately consolidated based on the Company's
50% ownership interest. Beginning in 1995, GEOILBENT has been included in the
consolidated financial statements based on a fiscal period ending September 30.
Results of operations in Russia reflect the twelve months ended December 31,
1993 and 1994, the nine months ended September 30, 1995 for 1995 and the three
months ended December 31, 1995 for the first quarter of 1996. The Company's
investment in GEOILBENT is proportionately consolidated based on the Company's
ownership interest, and for oil and gas reserve information, the Company reports
its 34% share of the reserves attributable to GEOILBENT.
    
 
The Company follows the full-cost method of accounting for its investments in
oil and gas properties. The Company capitalizes all acquisition, exploration,
and development costs incurred. The Company accounts for its oil and gas
properties using cost centers on a country by country basis. Proceeds from sales
of oil and gas properties are credited to the full-cost pools. Capitalized costs
of oil and gas properties are amortized within the cost centers on an overall
unit-of-production method using proved oil and gas reserves as audited by
independent petroleum engineers. Costs amortized include all capitalized costs
(less accumulated amortization), the estimated future expenditures (based on
current costs) to be incurred in developing proved reserves, and estimated
dismantlement, restoration and abandonment costs. See Note 1 to the Company's
Consolidated Financial Statements.
 
   
The following discussion of the financial condition and results of operations
for March 31, 1996, December 31, 1995 and 1994 and for each of the years in the
three year period ended December 31, 1995 and the three months ended March 31,
1996 and 1995, respectively, should be read in conjunction with the Company's
Consolidated Financial Statements and related Notes thereto.

Three Months ended March 31, 1996 and 1995
    
   
The Company had revenues of $32.9 million for the three months ended March 31,
1996. Expenses incurred during the period consisted of lease operating costs and
production taxes of $4.1 million, depletion, depreciation and amortization
expense of $7.7 million, general and administrative expense of $3.7 million,
interest expense of $2.3 million, partnership exchange expense of $2.1 million,
income tax expense of $4.4 million and a minority interest of $2.3 million. Net
income for the period was $6.3 million or $0.22 per share.
    
 
   
By comparison, the Company had revenues of $12.7 million for the three months
ended March 31, 1995. Expenses incurred during the period consisted of lease
operating costs and production taxes of $2.2 million, depletion, depreciation
and amortization expense of $3.1 million, general and administrative expense of
$1.7 million, interest expense of $1.6 million, income tax expense of $1.1
million and a minority interest of $0.9 million. Net income for the period was
$2.0 million or $0.08 per share.
    
 
   
Revenues increased $20.2 million, or 159%, during the three months ended March
31, 1996 compared to the corresponding period of 1995 primarily due to increased
oil sales in Venezuela. Sales quantities for the three months ended March 31,
1996 from Venezuela and Russia were 2,623,444 and 223,397 Bbl, respectively,
compared to 1,062,093 and 118,864 Bbl, respectively, for the three months ended
March 31, 1995. Prices for crude oil averaged $9.63 per Bbl (pursuant to terms
of an operating service agreement) from Venezuela and $10.32 per Bbl from Russia
for the three months ended March 31, 1996 compared to $9.02 per Bbl from
Venezuela and $13.12 per Bbl from Russia for the corresponding period of 1995.
Domestic sales quantities for the three months ended March 31, 1996 were 5,163
Bbl of crude oil and condensate and 1,249,128 Mcf of natural gas compared to
32,317 Bbl of crude oil and condensate and 346,548 Mcf of natural gas for the
three months ended March 31, 1995. Domestic prices for crude oil and natural gas
averaged $19.94 per Bbl and $3.26 per Mcf during the three months ended March
31, 1996 compared to $17.10 per Bbl and $1.62 per Mcf during the corresponding
period of 1995. Revenues for the three months ended March 31, 1996 were reduced
by a loss of $0.4 million related to a commodity hedge agreement compared to a
loss of $0.2 million during the corresponding period of 1995. Revenues for the
three months ended March 31, 1996 were increased by a foreign exchange gain of
$1.1 million compared to a gain of $0.1 million during the corresponding period
of 1995.
    
 
   
Lease operating costs and production taxes increased $1.9 million, or 86%,
during the three months ended March 31, 1996 compared to the three months ended
March 31, 1995 primarily due to the growth of the Company's Venezuelan
operations, but decreased as a percentage of total revenues. Depletion,
depreciation and amortization increased $4.6 million, or 148%, during the three
months ended March 31, 1996 compared to the corresponding period of 1995
primarily due to the increased oil production in Venezuela, but decreased as a
percentage of total revenues. Depletion expense per barrel of oil equivalent
produced from Venezuela, Russia and the United States during the three months
ended March 31, 1996 was $2.09, $3.52 and $6.47, respectively, compared to
$1.99, $2.76 and $6.97, respectively, during the corresponding period of the
previous year. General and administrative expenses increased $2.0 million, or
118%, during the three months ended March 31, 1996 compared to the corresponding
period of 1995 primarily due to the implementation of certain consulting and
related arrangements among Benton-Vinccler, the Company and Vinccler, Venezuelan
municipal taxes (which are a function of growing oil revenues) and the Company's
increased corporate activity associated with the growth of the Company's
business; but decreased slightly as a percentage of total revenues. Interest
expense increased $0.7 million, or 44%, during the three months ended March 31,
1996 compared to the three months ended March 31, 1995 primarily due to
increased borrowing to fund operations in Venezuela and Russia, but decreased
substantially as a percentage of total revenues. The Company incurred
partnership exchange expenses of $2.1 million during the three months ended
March 31, 1996 as a result of the completion of an exchange offer resulting in
the liquidation of three limited partnerships. Income tax expense increased $3.3
million, or 300%, during the three months ended March 31, 1996 compared to the
corresponding period of 1995 due primarily to increases in profitability in
Venezuela, the United States and Russia. The net income attributable to the
minority interest increased $1.4 million, or 156%, for the three months ended
March 31, 1996 compared to the three months ended March 31, 1995 as a result of
the increased profitability of Benton-Vinccler's operations in Venezuela.
    
 
Years Ended December 31, 1995 and 1994
The Company had revenues of $65.1 million for the year ended December 31, 1995.
Expenses incurred during the period consisted of lease operating costs and
production taxes of $10.7 million, depletion, depreciation and amortization
expense of $17.4 million, general and administrative expense of $9.4 million,
interest expense of $7.5 million, litigation settlement expenses of $1.7
million, income tax expense of $2.5 million and a minority interest of $5.3
million. Net income for the period was $10.6 million or $0.40 per share.
 
By comparison, the Company had revenues of $34.7 million for the year ended
December 31, 1994. Expenses incurred during the period consisted of lease
operating costs and production taxes of $9.5 million, depletion, depreciation
and amortization
 
                                       24

expense of $10.3 million, general and administrative expense of $5.2 million,
interest expense of $3.9 million, income tax expense of $0.7 million and a
minority interest of $2.1 million. The net income for the period was $3.0
million or $0.12 per share.
 
Revenues increased $30.4 million, or 87%, during the year ended December 31,
1995 compared to the corresponding period of 1994 primarily due to increased oil
sales in Venezuela. Sales quantities for the year ended December 31, 1995 from
Venezuela and Russia were 5,456,473 and 490,960 Bbls, respectively, compared to
2,519,514 and 294,364 Bbls, respectively, for the year ended December 31, 1994.
Prices per Bbl for crude oil averaged $9.01 (pursuant to terms of an operating
service agreement) from Venezuela and $12.25 from Russia for the year ended
December 31, 1995 compared to $8.52 and $11.93 from Venezuela and Russia,
respectively, for the year ended December 31, 1994. Domestic sales quantities
for the year ended December 31, 1995 were 68,975 Bbls of crude oil and
condensate and 3,784,830 Mcf of natural gas compared to 225,954 Bbls of crude
oil and condensate and 2,061,892 Mcf of natural gas for the year ended December
31, 1994. Domestic prices for crude oil and natural gas averaged $15.79 per Bbl
and $1.77 per Mcf during the year ended December 31, 1995 compared to $14.46 per
Bbl and $1.79 per Mcf during the year ended December 31, 1994. Revenues for the
year ended December 31, 1995 were reduced by a loss of $0.7 million related to a
commodity hedge agreement compared to a loss of $0.3 million in 1994. Revenues
for the year ended December 31, 1995 were increased by a foreign exchange gain
of $1.0 million compared to a gain of $1.4 million in 1994.
 
Lease operating costs and production taxes increased $1.2 million, or 12%,
during the year ended December 31, 1995 compared to 1994 primarily due to the
growth of the Company's Venezuelan operations, partially offset by the sale of
certain of the Company's interests in the West Cote Blanche Bay Field.
Depletion, depreciation and amortization increased $7.1 million, or 69%, during
the year ended December 31, 1995 compared to the corresponding period in 1994
primarily due to the increased oil production in Venezuela. Depletion expense
per BOE produced from Venezuela, United States and Russia during the year ended
December 31, 1995 was $2.09, $5.98 and $3.08, respectively, compared to $1.98,
$7.46 and $2.85, respectively, during the previous year. The increase in general
and administrative expenses of $4.2 million, or 80%, during the year ended
December 31, 1995 compared to 1994 was primarily due to the Company's increased
corporate activity associated with the growth of the Company's business. The
Company incurred litigation settlement expenses of $1.7 million during the year
ended December 31, 1995 as a result of a settlement agreement reached with
investors in partnerships which were sponsored by a third party. See Note 5 to
the Company's Consolidated Financial Statements. Interest expense increased $3.6
million, or 93%, in 1995 compared to 1994 primarily due to increased borrowing
to fund operations in Venezuela and Russia. Income tax expense increased $1.8
million, or 255%, during the year ended December 31, 1995 compared to 1994
primarily due to increased income taxes in Venezuela and Russia. The net income
attributable to the minority interest increased $3.2 million, or 153%, for 1995
compared to 1994 as a result of the increased profitability of Benton-Vinccler's
operations in Venezuela.
 
Years Ended December 31, 1994 and 1993
The Company had revenues of $34.7 million for the year ended December 31, 1994.
Expenses incurred during the period consisted of lease operating costs and
production taxes of $9.5 million, depletion, depreciation and amortization
expense of $10.3 million, general and administrative expense of $5.2 million,
interest expense of $3.9 million, income tax expense of $0.7 million, and a
minority interest of $2.1 million. The net income for the period was $3.0
million or $0.12 per share.
 
By comparison, the Company had revenues of $7.5 million for the year ended
December 31, 1993. Expenses incurred during the period consisted of lease
operating costs and production taxes of $5.1 million, depletion, depreciation
and amortization expense of $2.6 million, general and administrative expense of
$2.6 million and interest expense of $2.0 million. The net loss for the period
was $4.8 million or $0.26 per share.
 
Revenues increased $27.2 million, or 362%, during the year ended December 31,
1994 compared to the corresponding period of 1993 primarily due to increased
revenues from Benton-Vinccler's operations in Venezuela, the Company's increased
ownership of Benton-Vinccler, the initiation of oil sales in Russia in late
1993, gain on exchange rates in Venezuela and Russia, gas sales from the #831
well in the West Cote Blanche Bay Field and increased investment earnings. The
increase was partially offset by lower oil sales from the West Cote Blanche Bay
Field, lower sales prices and the sale of the Company's interest in the Pershing
property in 1993. Sales quantities for the year ended December 31, 1994 from
Venezuela and Russia were 2,519,514 and 294,364 Bbls, respectively, compared to
160,425 and 28,263 Bbls, respectively, for the year ended December 31, 1993.
Prices per Bbl for crude oil averaged $8.52 (pursuant to terms of an operating
service agreement) from Venezuela and $11.93 from Russia for the year ended
December 31, 1994 compared to $8.31 and $11.46 from Venezuela and Russia,
respectively, for the year ended December 31, 1993. Domestic sales quantities
for the year ended December 31, 1994 were 225,954 Bbls of crude oil and
condensate and 2,061,892 Mcf of natural gas compared to 292,266 Bbls of crude
oil and condensate and 232,677 Mcf of natural gas for the year ended December
31, 1993. Domestic prices for crude oil and natural gas averaged $14.46 per Bbl
and $1.79 per Mcf during the year ended December 31, 1994 compared to $17.30 per
 
                                       25
<PAGE>   26
 
Bbl and $2.19 per Mcf during the year ended December 31,1993. The Company has
realized net foreign exchange gains during 1994 primarily as a result of the
decline in the value of the Venezuelan bolivar and Russian rouble during periods
when Benton-Vinccler and GEOILBENT had substantial net monetary liabilities
denominated in bolivares and roubles.
 
Lease operating costs and production taxes increased $4.4 million, or 87%,
during the year ended December 31, 1994 compared to 1993 primarily due to the
growth of the Company's Venezuelan and Russian operations and were partially
offset by the sale of the Company's interest in certain property in 1993 and
reduced operating costs at the West Cote Blanche Bay Field. Depletion,
depreciation and amortization increased $7.7 million, or 291%, during the year
ended December 31, 1994 compared to 1993 primarily due to increased oil
production in Venezuela, gas sales from the #831 well in the West Cote Blanche
Bay Field and the initiation of oil production in Russia. Depletion expense per
BOE produced from the United States, Venezuela and Russia during the year ended
December 31, 1994 was $7.46, $1.98 and $2.85, respectively, compared to $6.47,
$1.43 and $3.51 during 1993. The increase in general and administrative expense
of $2.6 million, or 99%, in 1994 compared to 1993 was primarily due to the
growth of and the Company's increased ownership of Benton-Vinccler, the
commencement of operations in Russia and increased corporate activity associated
with the growth of the Company's business. Interest expense increased $1.9
million, or 99%, in 1994 compared to 1993 primarily due to increased borrowing
to fund operations in Venezuela and Russia.
 
The Company has included the results of operations of Benton-Vinccler in its
consolidated statement of income since January 1, 1994 and has reflected the 50%
ownership interest of Vinccler during January and February and the 20% ownership
interest of Vinccler thereafter as a minority interest. For the year ended
December 31, 1994, net income attributable to the minority interest was $2.1
million.
 
INTERNATIONAL OPERATIONS
 
The Company's costs of operations in Venezuela and Russia in 1993, 1994 and 1995
include certain fixed or minimum office, administrative, legal and personnel
related costs and certain start up costs, including short term facilities
rentals, organizational costs, contract services and consultants. Such costs are
expected to grow over time as operations increase. In the last two years such
costs have become less significant on a unit of production basis, but such costs
can be expected to fluctuate in the future based upon a number of factors. In
Venezuela, for the year ended December 31, 1993, the operating costs and general
and administrative expenses were $7.26 and $2.25 per Bbl, respectively. For the
year ended December 31, 1995 the operating costs and general and administrative
expenses for Venezuela decreased to $1.19 and $0.63 per Bbl, respectively. The
Company's Venezuelan operations grew considerably during 1994 and 1995, and are
expected to continue to grow, and its operating costs and general and
administrative expenses are expected to increase both in the aggregate and on a
per unit basis. In Russia, for the year ended December 31, 1993, the operating
costs and general and administrative expenses were $16.22 and $12.96 per Bbl,
respectively, decreasing to $5.63 and $1.16 per Bbl, respectively, for the year
ended December 31, 1995. The Company's Russian operations grew less
significantly than the Venezuelan operations during 1994 and 1995. Capital
expenditures through 1993 in both Venezuela and Russia focused on start-up
infrastructure items such as roads, pipelines, and facilities rather than
drilling. Beginning in 1994, a higher proportion of capital expenditures have
been and will continue to be spent on drilling and production activities. See
"Business -- South Monagas Unit, Venezuela -- Drilling and Development Activity"
and "-- North Gubkinskoye, Russia -- Drilling and Development Activity."
 
   
As a private contractor, Benton-Vinccler is subject to a statutory income tax
rate of 34%. However, Benton-Vinccler reported significantly lower effective tax
rates for 1994 and 1995 due to significant non-cash tax deductible expenses
resulting from devaluations in Venezuela when Benton-Vinccler had net monetary
liabilities in U.S. dollars. The Company cannot predict the timing or impact of
future devaluations in Venezuela. Any Company operations related to Delta Centro
will be subject to profit sharing, royalties and oil and gas industry taxation.
See "Summary -- Recent Developments" and "Business -- Delta Centro Block,
Venezuela."
    
 
GEOILBENT is subject to a statutory income tax rate of 35%. GEOILBENT has also
been subject to various other tax burdens, including an oil export tariff. The
export tariff was 30 ECU's per ton through 1995, although GEOILBENT obtained an
exemption from such tariff for 1995. The tariff was reduced to 20 ECU's per ton
in January 1996, and Russia has recently announced that effective July 1996, oil
export tariffs will be terminated. The Company anticipates that the tariff on
oil exporters may be replaced by an excise, pipeline or other tax levied on all
oil producers, but it is currently unclear how such other tax rates and regimes
will be set and administered.
 
EFFECTS OF CHANGING PRICES, FOREIGN EXCHANGE RATES AND INFLATION
 
The Company's results of operations and cash flow are affected by changing oil
and gas prices. However, the Company's Venezuelan revenues are based on a fee
adjusted quarterly by the percentage change of a basket of crude oil prices
instead of by
 
                                       26
<PAGE>   27
 
absolute dollar changes, which dampens both any upward and downward effects of
changing prices on the Company's Venezuelan revenues and cash flows. If the
price of oil and gas increases, there could be an increase in the cost to the
Company for drilling and related services because of increased demand, as well
as an increase in revenues. Fluctuations in oil and gas prices may affect the
Company's total planned development activities and capital expenditure program.
 
   
Effective May 1, 1994, the Company entered into a commodity hedge agreement with
Morgan Guaranty Trust Company of New York ("Morgan Guaranty") designed to reduce
a portion of the Company's risk from oil price movements. Pursuant to the hedge
agreement, with respect to the period from May 1, 1994 through the end of 1996,
the Company will receive from Morgan Guaranty $16.82 per Bbl and the Company
will pay to Morgan Guaranty the average price per Bbl of West Texas Intermediate
Light Sweet Crude Oil ("WTI") determined in the manner set forth in the hedge
agreement. Such payments will be made with respect to production of 1,000 Bbls
of oil per day for 1994, 1,250 Bbls of oil per day for 1995, and 1,500 Bbls of
oil per day for 1996. During the quarter ended March 31, 1996, the average price
per Bbl of WTI was $19.57 and the Company's net exposure for the quarter was
$0.4 million. The Company's total exposure for the year ended December 31, 1995,
under the hedge agreement was $0.7 million. The Company's oil production is not
materially affected by seasonality. The returns under the hedge agreement are
affected by world-wide crude oil prices, which are subject to wide fluctuation
in response to a variety of factors that are beyond the control of the Company.
    
 
   
There are presently no restrictions on conversion of currency in either
Venezuela or Russia. However, from June 1994 through April 1996, Venezuela
implemented exchange controls which significantly limited the ability to convert
local currency into U.S. dollars. Because payments made to Benton-Vinccler are
made in U.S. dollars into its United States bank account, and Benton-Vinccler is
not subject to regulations requiring the conversion or repatriation of those
dollars back into the country, the exchange controls did not have a material
adverse effect on Benton-Vinccler or the Company.
    
 
Within the United States, inflation has had a minimal effect on the Company, but
is potentially an important factor in results of operations in Venezuela and
Russia. With respect to Benton-Vinccler and GEOILBENT, substantially all of the
sources of funds, including the proceeds from oil sales, the Company's
contributions and credit financings, are denominated in U.S. dollars, while
local transactions in Russia and Venezuela are conducted in local currency.
Following the announcement of Venezuela's preliminary loan accord with the IMF
and the lifting of exchange controls, inflation will likely rise temporarily in
Venezuela and could be expected to have an adverse effect on Benton-Vinccler.
 
   
During the year ended December 31, 1995 and the three months ended March 31,
1996, the Company realized net foreign exchange gains, primarily as a result of
the decline in the value of the Venezuelan bolivar during periods when
Benton-Vinccler had substantial net monetary liabilities denominated in
bolivares. During the year ended December 31, 1995, the Company's net foreign
exchange gains attributable to its Venezuelan operations were $1.0 million and
net foreign exchange losses attributable to its Russian operations were $0.1
million. During the three months ended March 31, 1996, the Company's net foreign
exchange gains attributable to its Venezuelan and Russian operations were $1.0
million and $0.1 million, respectively. However, there are many factors
affecting foreign exchange rates and resulting exchange gains and losses, many
of which are beyond the influence of the Company. The Company has recognized
significant exchange gains and losses in the past, resulting from fluctuations
in the relationship of the Venezuelan and Russian currencies to the U.S. dollar.
It is not possible to predict the extent to which the Company may be affected by
future changes in exchange rates and exchange controls.
    
 
CAPITAL RESOURCES AND LIQUIDITY
 
The oil and gas industry is a highly capital intensive business. The Company
requires capital principally to fund the following costs: (i) drilling and
completion costs of wells and the cost of production and transportation
facilities; (ii) geological, geophysical and seismic costs; and (iii)
acquisition of interests in oil and gas properties. The amount of available
capital will affect the scope of the Company's operations and the rate of its
growth.

The net funds raised and/or used in each of the operating, investing and
financing activities for each of the years in the three year period ended
December 31, 1995 and the three months ended March 31, 1995 and 1996 are
summarized in the following table and discussed in further detail below:

At March 31, 1996, the Company had current assets of $64.2 million (including
$19.3 million and $2.0 million of cash restricted as collateral for loans to
Benton-Vinccler and GEOILBENT, respectively), and current liabilities of $61.5
million (including loans of $19.3 million and $0.6 million collateralized by
restricted cash), resulting in working capital of $2.7 million and a current
ratio of 1.04:1. This compares to the Company's working capital deficit of $2.9
million at December 31, 1995. The increase of $5.6 million was due primarily to
working capital generated from operations in excess of capital expenditures.
    
 
Cash Flow from Operating Activities
   
During the three months ended March 31, 1996 and the years ended December 31,
1995 and 1994, net cash provided by operating activities was approximately $15.8
million, $32.4 million and $13.5 million, respectively, and during 1993, net
cash used in operating activities was approximately $1.8 million. Cash flow from
operating activities increased by $18.9 million and $15.3 million in 1995 and
1994, respectively, over the prior year, and $10.4 million during the three
months ended March 31, 1996 compared to the corresponding period of the prior
year, due primarily to increased oil and gas production in Venezuela.
    
 
Cash Flow from Investing Activities
   
During the three months ended March 31, 1996, the Company had drilling and
production related capital expenditures of approximately $17.4 million, of which
$12.0 million was attributable to the development of the South Monagas Unit in
Venezuela, $1.8 million related to the development of the North Gubkinskoye
Field in Russia, $1.7 million related to drilling activity in the West Cote
Blanche Bay, Rabbit Island and Belle Isle Fields in Louisiana, and $1.9 million
was attributable to other projects. During 1995, 1994 and 1993, the Company had
drilling and production related capital expenditures of approximately $68.3
million, $39.6 million and $26.2 million, respectively. Of the 1995
expenditures, $49.0 million was attributable to the development of the South
Monagas Unit in Venezuela, $12.4 million related to the development of the North
Gubkinskoye Field in Russia, $6.0 million related to drilling activity in the
West Cote Blanche Bay, Rabbit Island and Belle Isle Fields in Louisiana, and
$0.9 million was attributable to other projects. The Company also sold certain
oil and gas properties for net proceeds of approximately $1.3 million, $15.4
million, $5.8 million and $7.8 million during the three months ended March 31,
1996 and the years ended December 31, 1995, 1994 and 1993, respectively.
    
 
In April 1996, the Company sold to Shell all of its interests in the West Cote
Blanche Bay, Rabbit Island and Belle Isle Fields for a purchase price of $35.4
million. Proceeds of the sale will be used to repay debt as described below and
for working capital purposes in Venezuela and other international activities.
 
Cash Flow from Financing Activities
   
In May 1996, the Company issued $125 million in aggregate principal amount of
Old Notes. A portion of the proceeds therefrom was used to repay certain long
term indebtedness and the remainder will be used for repayment of certain short
term obligations and for capital expenditure and working capital purposes.
    
 
   
On June 30, 1995, the Company issued $20 million in senior unsecured notes due
June 30, 2007, with interest at 13% per annum. The note agreement contained
financial covenants and provided for limitations on sales of assets. The Company
prepaid these senior unsecured notes from the proceeds of the sale of the Old
Notes and paid a prepayment premium of approximately $7.4 million. The holders
of the senior notes provided consent to the sale of the U.S. properties and such
consent requires payment of the notes on or before June 30, 1996.
    
 
On September 30, 1994, the Company issued $15 million in senior unsecured notes
due September 30, 2002, with interest at 13% per annum. The note agreement
contained financial covenants and provided for limitations on sales of assets.
Upon

consummation of the U.S. Property Sale, the Company prepaid the outstanding
principal and accrued interest on these senior notes, with a prepayment premium
of approximately $3.2 million.
 
On December 27, 1994, the Company entered into a revolving secured credit
facility with a commercial bank. Under the terms of the credit agreement, the
Company could borrow up to $15 million, with the initial available principal
limited to $10 million. The credit facility was secured by the U.S. properties.
The Company repaid the principal outstanding of approximately $5 million, with
accrued interest, and made a payment for the net profits interest of $1.8
million upon closing the U.S. Property Sale.
 
In February 1994, the Company and Benton-Vinccler entered into a six month loan
arrangement with Morgan Guaranty to repay commercial paper and for working
capital requirements, which has subsequently been renewed on a monthly basis.
Under such arrangement, Benton-Vinccler may borrow up to $25 million, of which
$10 million may be borrowed on a revolving basis. Borrowings under this loan
arrangement are secured by cash collateral in the form of a time deposit from
the Company. The loan arrangement contains no restrictive covenants and no
financial ratio requirements. The principal amount of such loan outstanding at
December 31, 1995 was $19.3 million. Benton-Vinccler can borrow an additional
$5.7 million under the loan arrangement if the Company provides a time deposit
to secure such additional borrowings.
 
In October 1995, the Company and GEOILBENT entered into a loan arrangement with
Morgan Guaranty for working capital requirements. Under such arrangement,
GEOILBENT may borrow up to $10 million on a revolving basis. Borrowings under
this loan arrangement are secured by cash collateral in the form of a time
deposit by the Company. The loan arrangement contains no restrictive covenants
and no financial ratio requirements. The principal amount of such loan
outstanding at December 31, 1995 was $0.6 million.
 
   
On May 30, 1996, the Company entered into a Credit Agreement with Morgan
Guaranty. The Credit Agreement provides for the issuance of a letter of credit
in the amount of $18,000,000 to be used to secure the Company's performance
under its agreements related to the development of the Delta Centro Block in
Venezuela. The letter of credit will be secured by cash collateral in the form
of a time deposit from the Company. Morgan Guaranty will receive an arrangement
fee and will receive a fee of .25% per annum computed on the daily average
maximum available amount of the letter of credit. In addition, the Credit
Agreement provides for a $20,000,000 unsecured revolving credit facility which
must be repaid on or before March 14, 1998. Borrowings under such facility
accrue interest at per annum rate equal to the sum of the Euro-Dollar margin
plus the Adjusted London Interbank Offered Rate for such interest period. The
Euro-Dollar margin will be 3% until September 14, 1997 and 3.75% per annum
thereafter. The revolving credit facility is secured by a guarantee by the
Company's subsidiary Benton-Vinccler, C.A. and a security interest in all
payments made to Benton-Vinccler, C.A. under its Service Agreement with Fagoven,
S.A. The Credit Agreement contains covenants and restrictions that are
substantially the same as those provided in the Indenture.
    
 
   
The Company expects 1996 capital expenditures to be approximately $100 million,
including $12 million in expenditures for Russia (net to the Company's interest)
which is dependent on proposed EBRD or other financing, which may or may not be
obtained. See "Business -- North Gubkinskoye, Russia -- Drilling and Development
Activity." Funding is expected to come from the proceeds from the sale of the
Old Notes, cash flow from operations, sales of property interests, or project
and trade financing sources. There can be no assurance that such financing will
become available under terms and conditions acceptable to the Company, which may
result in reduced capital expenditures in the Company's principal areas of
operations.

GENERAL
 
The Company is an independent energy company which has been engaged in the
development and production of oil and gas properties since 1989. Although
originally active only in the United States, the Company has developed
significant interests in Venezuela and Russia, and recently sold substantially
all of its remaining United States oil and gas interests. The Company's
operations are conducted principally through its 80%-owned Venezuelan
subsidiary, Benton-Vinccler which operates in the South Monagas Unit in
Venezuela, and its 34%-owned Russian joint venture, GEOILBENT, which operates in
the North Gubkinskoye Field in Siberia, Russia.
 
   
As of December 31, 1995, the Company had total assets of $214.8 million ($234.9
million at March 31, 1996), total estimated proved reserves of 96,212 MBOE, and
a standardized measure of discounted future net cash flow, before income taxes,
for total proved reserves of $372.3 million. For the year ended December 31,
1995 and the three months ended March 31, 1996, the Company had total revenues
of $65.1 million and $32.9 million, respectively and net income of $10.6 million
and $6.3 million, respectively.
    
 
The Company has been successful in increasing reserves, production, revenues and
earnings during the last two years. From year end 1993 through 1995, estimated
proved reserves increased from 42,785 MBOE to 96,212 MBOE and net production
increased from a total of 519 MBOE in 1993 to 6,647 MBOE in 1995. As production
has increased over this period, average lifting costs per Bbl have declined from
$7.26 to $1.19 in Venezuela, and from $16.22 to $5.63 in Russia. Over the same
period, earnings per share have increased from a loss of $0.26 per share in 1993
to income of $0.40 per share for the year ended December 31, 1995.
 
The Company was incorporated in Delaware in September 1988 and its principal
executive offices are located at 1145 Eugenia Place, Suite 200, Carpinteria,
California 93013, and its telephone number is (805) 566-5600.
 
BUSINESS STRATEGY
 
The Company's business strategy is to identify and exploit new oil and gas
reserves in under-developed areas while seeking to minimize the associated risk
of such activities. Specifically, the Company endeavors to minimize risk by
employing the following strategies in its business activities: (i) seek new
reserves in areas of low geologic risk; (ii) use proven advanced technology in
both exploration and development to maximize recovery; (iii) establish a local
presence through joint venture partners and the use of local personnel; (iv)
commit capital in a phased manner to limit total commitments at any one time;
and (v) reduce foreign exchange risks through receipt of revenues in U.S.
currency.
 
- - SEEK NEW RESERVES IN AREAS OF LOW GEOLOGIC RISK. The Company has had
significant success in identifying under-developed reserves in the U.S. and
internationally. In particular, the Company has notable experience and expertise
in seeking and developing new reserves in countries where perceived potential
political and operating difficulties have sometimes discouraged other energy
companies from competing. As a result, the Company has established operations in
Venezuela and Russia which have significant reserves that have been acquired and
developed at relatively low costs. The Company is seeking similar opportunities
in other countries and areas which it believes have high potential.
 
- - USE OF PROVEN ADVANCED TECHNOLOGY IN BOTH EXPLORATION AND DEVELOPMENT. The
Company's use of 3-D seismic technology, in which a three dimensional image of
the earth's subsurface is created through the computer interpretation of seismic
data, combined with its experience in designing the seismic surveys and
interpreting and analyzing the resulting data, allow for a more detailed
understanding of the subsurface than do conventional surveys. Such technology
contributes significantly to field appraisal, development and production. The
3-D seismic information, in conjunction with subsurface geologic data from
previously drilled wells, is used by the Company's experienced in-house
technical team to identify previously undetected reserves. The 3-D seismic
information can also be used to guide drilling on a real-time basis, and has
been especially helpful in the horizontal drilling done in Venezuela in order to
take advantage of oil-trapping faults.
 
- - ESTABLISH A LOCAL PRESENCE THROUGH JOINT VENTURE PARTNERS AND THE USE OF LOCAL
PERSONNEL. The Company has sought to establish a local presence where it does
business to facilitate stronger relationships with local government and labor
 
                                       30
<PAGE>   31
 
through joint venture arrangements with local partners. Moreover, the Company
employs almost exclusively local personnel to run foreign operations both to
take advantage of local knowledge and experience and to minimize cost. These
efforts have created an expertise within Company management in forming effective
foreign partnerships and operating abroad. The Company believes that it has
gained access to new development opportunities as a result of its reputation as
a dependable partner.
 
- - COMMIT CAPITAL IN A PHASED MANNER TO LIMIT TOTAL COMMITMENTS AT ANY ONE
TIME. While the Company typically has agreed to a minimum capital expenditure or
development commitment at the outset of new projects, expenditures to fulfill
these commitments are phased over time. In addition, the Company seeks, where
possible, to use internally generated funds for further capital expenditures and
to invest in projects which provide the potential for an early return to the
Company.
 
- - REDUCE FOREIGN EXCHANGE RISKS. The Company seeks to reduce foreign currency
exchange risks by providing for the receipt of revenues by the Company in U.S.
dollars while most operating costs are incurred in local currency. Pursuant to
the operating agreement between Benton-Vinccler and Lagoven, the operating fees
earned by the Company are paid directly to the Company's bank account in the
U.S. in U.S. dollars. GEOILBENT receives revenues from export sales in U.S.
dollars paid to its account in Moscow. As the Company expands internationally,
it will seek to establish similar arrangements for new operations.

SOUTH MONAGAS UNIT, VENEZUELA
 
General
In July 1992, the Company and Vinccler, a Venezuelan construction and
engineering company, signed a 20-year operating service agreement with Lagoven,
an affiliate of the national oil company, PdVSA, to reactivate and further
develop the Uracoa, Tucupita and Bombal Fields, which are a part of the South
Monagas Unit (the "Unit"). At that time, the Company was one of three foreign
companies ultimately awarded an operating service agreement to reactivate
existing fields by PdVSA, and was the first U.S. company since 1976 to be
granted such an oil field development contract in Venezuela.
 
The oil and gas operations in the Unit are conducted by Benton-Vinccler, the
Company's 80%-owned subsidiary. The remaining 20% of the outstanding capital
stock of Benton-Vinccler is owned by Vinccler. The Company, through its majority
ownership of
 
                                       31
<PAGE>   32
 
stock in Benton-Vinccler, makes all operational and corporate decisions related
to Benton-Vinccler, subject to certain super-majority provisions of
Benton-Vinccler's charter documents related to mergers, consolidations, sales of
substantially all of its corporate assets, change of business and similar major
corporate events. Vinccler has an extensive operating history in Venezuela. It
provided the Company with initial financial assistance and continues to provide
ongoing assistance with construction services and governmental and labor
relations.
 
Under the terms of the operating service agreement, Benton-Vinccler is a
contractor for Lagoven and is responsible for overall operations of the South
Monagas Unit, including all necessary investments to reactivate and develop the
fields comprising the Unit. The Venezuelan government maintains full ownership
of all hydrocarbons in the fields. In addition, Lagoven maintains full ownership
of equipment and capital infrastructure following its installation.
Benton-Vinccler invoices Lagoven each quarter based on Bbls of oil accepted by
Lagoven during the quarter, using quarterly adjusted contract service fees per
Bbl, and receives its payments from Lagoven in U.S. dollars deposited directly
into a U.S. bank account. The operating service agreement provides for
Benton-Vinccler to receive an operating fee for each Bbl of crude oil delivered
and a capital recovery fee for certain of its capital expenditures, provided
that such operating fee and capital recovery fee cannot exceed the maximum total
fee per Bbl set forth in the agreement. The operating fee is subject to periodic
adjustments to reflect changes in the special energy index of the U.S. Consumer
Price Index, and the maximum total fee is subject to periodic adjustments to
reflect changes in the average of certain world crude oil prices. Since
commencement of operations, the adjusted maximum total fee has been cumulatively
less than the adjusted operating fee, resulting in no capital recovery fee. The
Company cannot predict the extent to which future maximum total fee adjustments
will provide for capital recovery components in the fees it receives, and has
recorded no income or asset for capital recovery fees.
 
Under the terms of the operating service agreement, Benton-Vinccler was
obligated to make certain capital and operating expenditures prior to December
31, 1995. Benton-Vinccler has satisfied all such obligations under the operating
service agreement and no further capital commitments are contractually required.
However, in order to expand operations, the Company will need to continue to
make capital expenditures. See "-- South Monagas Unit, Venezuela -- Drilling and
Development Activity."
 
Since 1992, when Venezuela solicited initial calls for indications of interest
related to the reactivation and further development of certain fields in
Venezuela, the country has continued to invite foreign assistance in Venezuelan
oil and gas exploration, development and production. Management believes that
Venezuela continues to provide potential business opportunities for the Company.
See "-- Delta Centro Block, Venezuela."
 
Location and Geology
The Unit is located in the southeastern part of the state of Monagas in eastern
Venezuela. The Unit is approximately 51 miles long and eight miles wide and
consists of 157,843 acres, of which the fields comprise approximately one-half.
At December 31, 1995, proved reserves attributable to the Company's Venezuelan
operations were 73,593 MBOE, which represented approximately 76% of the
Company's proved reserves. Benton-Vinccler is currently developing the Oficina
sands in the Uracoa Field, which contain 92.4% of the Unit's proved reserves.
The associated natural gas which is produced is currently being reinjected into
the field, as no ready market exists for the natural gas.
 
Drilling and Development Activity
   
Uracoa Field. Benton-Vinccler has been developing the Uracoa Field since 1992.
During May 1996, approximately 63 wells were producing an average of
approximately 33.6 MBbls of oil per day in the Uracoa Field. The following table
sets forth Uracoa drilling activity and production information for each of the
quarters presented:

Benton-Vinccler contracts with third parties for drilling and completion of
wells. Currently, Helmerich & Payne International Drilling Co. and Exeter
Drilling Co. are performing drilling services for Benton-Vinccler under
contract. The Company's technical personnel identify drilling locations, specify
the drilling program and equipment to be used and monitor the drilling
activities. To date, 14 previously drilled wells have been reactivated and 46
new wells have been drilled in the Uracoa Field using modern drilling and
completion techniques that had not previously been utilized on the field, with
45, or 98%, completed and placed on production. Two drilling rigs are currently
working in the field. In the Company's recent experience, each vertical deviated
well, drilled to an average depth of 5,600 feet, has been drilled in
approximately 10 days and completed in approximately 6 days, and each horizontal
well, drilled to an average depth of 6,500 feet, has been drilled in 20 days and
completed in 3 days. Benton-Vinccler plans to drill approximately 7 vertical and
26 horizontal wells, 2 injection wells and one step-out well adjacent to the
Uracoa Field during 1996, at an anticipated cost of $40-45 million.
    
 
In December 1993, Benton-Vinccler commenced drilling the first horizontal well
in the Uracoa Field. Since the completion of this well, the Company has
successfully integrated modern technology and modern drilling and completion
techniques to improve the ultimate recovery. The Company has conducted a 3-D
seismic survey and interpreted the seismic data over the Uracoa Field. As a
horizontal well is drilled, information regarding formations encountered by the
drill bit is transmitted to the Company. Geologists, engineers and geophysicists
at the Company can determine the location of the drill bit by comparing the
information about the formations being drilled with the 3-D seismic data. The
Company then directs the movement of the drill bit to more accurately direct the
well to the expected reservoir. The Company intends to continue this method of
horizontal drilling in the development of the field.
 
Once oil is produced in the Uracoa Field, it is transported to production
facilities, which were designed in the United States and installed by
Benton-Vinccler. These production facilities are of the type commonly used in
heavy oil production in the United States, but not previously used extensively
in Venezuela to process crude oil of similar gravity or quality. The current
production facilities are capable of processing 30-35 MBbls of oil per day.
Benton-Vinccler intends to expand the capacity of the production facilities in
1996 to a total capacity of 40-45 MBbls of oil per day. The Company anticipates
capital expenditures of $21 million during 1996 to complete such expansion.
 
   
Tucupita and Bombal Fields. Before becoming inactive, only Tucupita had been
substantially developed and produced; relatively few wells had been drilled at
Uracoa and Bombal. Benton-Vinccler has completed a 67-square mile 3-D seismic
survey over portions of the Unit and is currently interpreting the data. Based
on the interpretations of the seismic data, Benton-Vinccler may drill one or
more wells to extend the boundaries of the three known fields or to confirm the
existence of additional fields previously undetected in the area. Further
analysis of the Unit indicates that significant reserves may remain in the
Tucupita Field. Benton-Vinccler intends to evaluate the potential of the
Tucupita Field in 1996 by drilling one oil well, and will expand existing
production facilities in such field. Based on the performance of this pilot oil
well, and if the Company's assumptions prove to be correct, the production
facilities will be further expanded, and a pipeline to the Uracoa Field will be
installed. The pipeline will also be used for production from the Bombal Field
when it is developed. Benton-Vinccler currently plans to begin to reactivate and
develop the Bombal Field beginning later in 1996. During 1996, the Company
expects capital expenditures of $5-7 million for drilling and construction of
facilities in the Tucupita and Bombal Fields.
    
 
Customers and Market Information
Oil produced in Venezuela is delivered to Lagoven under the terms of an
operating service agreement for an operating service fee. Benton-Vinccler has
constructed a 25-mile oil pipeline from its oil processing facilities at Uracoa
to Lagoven's storage facility, which is the custody transfer point. The service
agreement specifies that the oil stream may contain no more than 1% base
sediment and water, and quality measurements are conducted both at
Benton-Vinccler's facilities and at Lagoven's storage facility. A continuous
flow measuring unit is installed at Benton-Vinccler's facility, so that quantity
is monitored constantly. Lagoven provides Benton-Vinccler with a daily
acknowledgment regarding the amount of oil accepted the previous day, which is
reconciled to Benton-Vinccler's measurement. At the end of each quarter,
Benton-Vinccler prepares an invoice to Lagoven for that quarter's deliveries.
Lagoven pays the invoice at the end of the second month after the end of the
quarter. Invoice amounts and payments are denominated in U.S. dollars. Payments
are wire transferred into Benton-Vinccler's account in New York.
 
Employees; Community Relations
Benton-Vinccler seeks to employ nationals rather than bring expatriates into the
country. Presently, there are five full-time expatriates working with
Benton-Vinccler and 121 local employees. Benton-Vinccler also conducts ongoing
community relations programs, providing medical care, training, equipment and
supplies, and support for local schools, in both states in which the South
Monagas Unit falls.

DELTA CENTRO BLOCK, VENEZUELA
 
General
In January 1996, the Company and its bidding partners, LL&E and Norcen, were
awarded the right to explore and develop the Delta Centro Block in Venezuela.
The contract requires a minimum exploration work program consisting of
completing a 1,300 kilometer seismic survey and drilling three wells to depths
of 12,000 to 18,000 feet within five years. PdVSA estimates that this minimum
exploration work program will cost $60 million, and will require that the
Company, LL&E and Norcen each post a performance surety bond or standby letter
of credit for its pro rata share of the estimated work commitment expenditures.
The Company will have a 30% interest in the exploration venture, with LL&E and
Norcen each owning a 35% interest. Under the proposed terms of the operating
agreement, which establishes the management company for the project, LL&E will
be the operator of the field and therefore the Company will not be able to
exercise control of the operations of the venture. It is currently proposed that
Corporacion Venezolana del Petroleo, S.A. ("CVP"), an affiliate of the national
oil company, will have a 35% interest in the management company, which will
dilute the voting power of the partners on a pro rata basis.
 
If areas within the block are deemed to be commercially viable, then the group
has the right to enter into further agreements with CVP to develop those areas
during the next 20-25 years. CVP would participate in the revenues and costs
with an interest between 1-35%, at CVP's discretion. Any oil and gas produced by
the Delta Centro consortium will be sold at market prices and will be subject to
the oil and gas taxation regime in Venezuela and to the terms of a profit
sharing agreement with PdVSA. Under the current oil and gas tax law, a royalty
of up to 16.67% will be paid to the state. Under the contract bid terms, 41% of
the pre-tax income will be shared with PdVSA for the period during which the
first $1 billion of revenues is produced; thereafter, the profit sharing amount
may increase to up to 50% according to a formula based on return on assets.
Currently, the statutory income tax rate for oil and gas enterprises is 66.7%.
Royalties and shared profits are currently deductible for tax purposes.
 
Location and Geology
The Delta Centro block consists of approximately 2,100 square kilometers
(526,000 acres) located in the delta of the Orinoco River in the eastern part of
Venezuela. Although no significant exploratory activity has been conducted on
the block, PdVSA has estimated that the area may contain recoverable reserves of
as much as 820 MMBbls, and may be capable of producing up to 160 MBbls of oil
per day. The general area of Venezuela in which the Delta Centro Block is
located is known to be a significant source of hydrocarbons, evidenced by the
Orinoco tar sands to the south and the recently discovered El Furrial light oil
trend to the north. Based on its geological studies of the basins in this area,
the Company's technical staff believes that hydrocarbons have essentially
migrated over time from the deeper Maturin basin area of Venezuela southward
toward the shallower Orinoco tar belt area. If so, then potential trapping
structures and/or faults in the path of the migrating oil would serve as traps
for the migrating oil and have the opportunity to be filled to their spill
points. Delta Centro is directly in line with this migration path, making it an
attractive exploration area. The area is mostly swampy in nature, with terrain
ranging from forest in the north to savannah in the south. The marshlands in the
block are similar to the transition zone areas in the Gulf of Mexico in which
the Company has significant experience in seismic and drilling operations.
 
Drilling and Development Activity
The venture intends to conduct a 3-D seismic survey over the southwestern
portion of the Delta Centro Block beginning in 1996, at an expected total cost
to the Company of approximately $6-7 million, of which $2 million is expected to
be spent in 1996. Following the initial interpretation of the seismic data, the
venture intends to drill an initial exploration well during 1997, at a cost to
the Company of approximately $1.5-2 million. Seismic and drilling programs
during 1998-2000 will be based on the results of the 1996-1997 activity.
 
OVERVIEW OF VENEZUELAN OIL AND GAS INDUSTRY
 
Oil and gas is a vital industry in Venezuela, currently representing 25% of the
economy. Estimates by the Economist Intelligence Unit indicate that the oil
sector grew 6.0% in 1995 and 4.6% in 1994. Oil, gas and petroleum product
exports for 1995 reached $13.3 billion, accounting for almost 73% of total
exports. In addition, such estimates indicate that PdVSA expects oil and gas
product exports to total approximately $15.6 billion in 1996.
 
PdVSA is one of the largest oil companies in the world based on several factors,
including reserves, production capacity and product sales. At the end of 1995,
PdVSA's proved crude oil reserves were approximately 64 BBbls, more reserves
than any other company or country in the Western hemisphere. PdVSA is seeking to
double its current production capacity over the next ten years, with private
investment as a key source of capital to achieve such growth.
 
In 1992, Venezuela initiated a field re-activation program, which was an
important first step for the reentrance of private investment to the oil and gas
sector. Service contracts for 15 underdeveloped units were awarded, nine of
which currently produce

<PAGE>   35
 
a total of 100 MBbls per day. Benton-Vinccler currently provides approximately
30% of this total production. In the beginning of 1996, Venezuela opened the oil
and gas sector for profit sharing contracts. Ten areas were offered for auction
at the end of January, marking the first time that exploration and production
rights had been officially offered to the private sector since the
nationalization of the oil industry in 1976. The Delta Centro consortium was one
of the successful bidders.
 
NORTH GUBKINSKOYE, RUSSIA
 
General
In December 1991, the joint venture agreement forming GEOILBENT among the
Company (34% interest) and two Russian partners, Purneftegasgeologia and
Purneftegas (each having a 33% interest), was registered with the Ministry of
Finance of the USSR. In November 1993, the agreement was registered with the
Russian Agency for International Cooperation and Development. Although GEOILBENT
may only take action through the unanimous vote of the partners, the Company
believes that it has developed a good relationship with its partners and has not
experienced any disagreement with its partners on major operational matters. Mr.
A.E. Benton, Chief Executive Officer of the Company, serves as Chairman of the
Board of GEOILBENT.
 
Location and Geology
GEOILBENT develops, produces and markets crude oil from the North Gubkinskoye
Field in the West Siberia region of Russia, located approximately 2,000 miles
northeast of Moscow. The field, which covers an area approximately 15 miles long
and 4 miles wide, has been delineated with over 60 exploratory wells (which
tested 26 separate reservoirs) and is surrounded by large proven fields. Before
commencement of GEOILBENT's operations, North Gubkinskoye was one of the largest
oil and gas fields in the region not under commercial production. The field is a
large anticlinal structure with multiple pay sands. The development to date has
focused on the BP 8, 9, 10, 11 and 12 reservoirs. The natural gas which is
produced is currently being flared in accordance with environmental regulations.
 
Drilling and Development Activity
   
GEOILBENT commenced initial operations in the field during the third quarter of
1992 with the construction of a 37-mile oil pipeline and installation of
temporary production facilities. During May 1996, approximately 38 wells were
producing an average of approximately 6.4 MBbls of oil per day. The following
table sets forth drilling activity and production information for each of the
quarters presented:

GEOILBENT contracts with third parties for drilling and completion of wells.
Supervised by a joint American and Russian management team, GEOILBENT identifies
drilling locations, then uses Russian drilling rigs, upgraded by certain western
technology and materials including shaker screens, monitoring equipment and
drilling and completion fluids, to drill and complete a well. To date, 12
previously drilled wells have been reactivated and 38 wells have been drilled in
the field, with 37, or 97%, completed and placed on production. Four drilling
rigs are currently working on pads in the field, and once all wells on the pad
have been drilled, each such well will be tested for completion. Each well is
drilled to an average depth of approximately 10,000 feet measured depth and
8,000 feet true depth.
    
 
Once oil is produced from the North Gubkinskoye Field, it is transported to
production facilities constructed and owned by GEOILBENT. Oil is then
transferred to GEOILBENT's 37-mile pipeline which transports the oil from the
North Gubkinskoye Field south to the main Russian oil pipeline network.
 
                                       35
<PAGE>   36
 
   
The current production facilities are operating at or near capacity and would
need to be expanded to accommodate any increased production. Subject to
obtaining financing, GEOILBENT has a 1996 capital expenditure budget of
approximately $35 million, of which $21 million would be used to drill
approximately 36 wells in the North Gubkinskoye Field and $14 million for
construction of production facilities. Although no assurance can be given that
such financing will be obtained, GEOILBENT and the Company continues discussions
with the European Bank for Reconstruction and Development ("EBRD") for a
proposed credit facility, which would be non-recourse to the Company, to be used
for development of the North Gubkinskoye Field, including the production
facility expansion. If EBRD or other financing is not completed, minimal capital
expenditures are anticipated and production from the field is expected to
experience a natural decline.
    
 
Customers and Market Information
GEOILBENT's 37-mile pipeline runs from the field to the main pipeline in the
area where GEOILBENT transfers the oil to Transneft, the state oil pipeline
monopoly. Transneft can transport the oil to the western border of Russia. All
oil production is for export and all oil sales are handled by trading companies
such as Russoil or NAFTA Moscow. During 1995, most of GEOILBENT's crude sales
were made to purchasers in Germany. All sales have been paid in U.S. dollars
into GEOILBENT's account in Moscow.
 
Employees; Community and Country Relations
Having access to the oilfield labor base in West Siberia, GEOILBENT employs
Russian nationals almost exclusively. Presently, there are three full-time
expatriates working with GEOILBENT and over 200 local employees. The Company
conducts an ongoing community relations program in Russia, providing medical
care, training, equipment and supplies in towns in which GEOILBENT personnel
reside and also for the nomadic indigenous population which resides in the area
of oilfield operations.
 
Alternatives for Natural Gas Reserves
The Company and GEOILBENT estimate that substantial recoverable associated gas
and condensate reserves exist in the North Gubkinskoye Field. In addition, there
are substantial non-associated natural gas reserves in the field. Currently,
there exists no ready market for these reserves, and therefore there are no
plans to produce these gas and condensate reserves. Associated gas and
condensate are flared in allowable amounts under permits with the Ministry of
Fuel and Energy. If no market develops for the gas and condensate, then over
time GEOILBENT plans to begin reinjecting them back into the reservoirs.
GEOILBENT currently has no rights to develop the gas caps in the field. However,
GEOILBENT has recently entered into discussions with Gazprom, the state natural
gas monopoly, for development and production of the solution gas, which is
estimated by the Company to be 550-600 Bcf. Implementation of such a development
plan would include construction of processing facilities and of a natural gas
pipeline from the field area to the main transmission pipeline. Feasibility
studies are currently in process and anticipated to be completed by year end
1996. Further development, subject to approval of all parties, will depend upon
available financing.
 
Importance of Russian Oil and Gas Industry
Although estimates vary widely, it is believed that a substantial amount of oil
and natural gas reserves are located in Russia. In 1994 and 1995, energy and
fuels (including primarily oil, oil products, natural gas, and hard coal)
accounted for approximately 45% and 41%, respectively, of total Russian exports,
as reported by the Economist Intelligence Unit. These fuel and energy exports
are important sources of hard currency. In the last several years, the Russian
oil and gas industry has attracted a notable amount of foreign investment,
including that of the Company.
 
OTHER PROPERTIES
 
Prior to 1996, the Company had successfully pursued acquisition and joint
venture opportunities in the United States as major oil and gas companies
continued to consolidate operations and focus exploration and development
activities outside the United States. Substantially all of the Company's
domestic activities were located in the Louisiana Gulf Coast at the West Cote
Blanche Bay, Rabbit Island and Belle Isle Fields. The Company entered into
agreements with Texaco, Inc. ("Texaco") and Oryx Energy Company ("Oryx") to
produce the fields by using 3-D seismic technology integrated with subsurface
geologic data from previously drilled wells. In addition, the Company entered
into certain agreements with Tenneco Ventures Corporation ("Tenneco") whereby
Tenneco purchased certain interests in the Company's operations in the three
fields and was given the right to participate as a 50% partner in certain of the
Company's future activities in the Gulf Coast for the next five years.
 
In March 1995, the Company and its affiliates and Tenneco sold to WRT Energy
Corporation a 43.75% working interest in the shallower depths (above
approximately 10,575 feet) in the West Cote Blanche Bay Field for an aggregate
purchase price of $20 million. Of this aggregate purchase price, the Company
received $14.9 million.
 
                                       36
<PAGE>   37
 
On April 12, 1996, the Company sold to Shell all of its interests in the West
Cote Blanche Bay, Rabbit Island and Belle Isle Fields, effective December 31,
1995, for a purchase price of $35.4 million. Because the properties were held
for sale, the Company's reserve report excludes all reserves attributable to
these properties.
 
At December 31, 1995, the Company had proved reserves of 1 MBOE in the Scott
Field in Louisiana.
 
EVALUATION OF ADDITIONAL OPPORTUNITIES
 
The Company continues to evaluate and pursue additional international
opportunities which fit within the Company's business strategy. The Company is
currently evaluating certain development and/or acquisition opportunities, but
it is not presently known whether, or on what terms, such evaluations will
result in future agreements or acquisitions.

(1) Includes 100% of the reserve information, without deduction for minority
    interest. All Venezuelan reserves are attributable to an operating service
    agreement between Benton-Vinccler and Lagoven, under which all mineral
    rights are owned by the Government of Venezuela. See "-- South Monagas Unit,
    Venezuela."
 
(2) Although the Company estimates that there are substantial natural gas
    reserves in the North Gubkinskoye Field, no natural gas reserves have been
    recorded because of a lack of a ready market.
 
(3) The Company has entered into an agreement to sell substantially all of its
    U.S. reserves and acreage positions. See "-- Other Properties." The table
    excludes the reserves to be sold.
 
Estimates of commercially recoverable oil and gas reserves and of the future net
cash flows derived therefrom are based upon a number of variable factors and
assumptions, such as historical production from the subject properties,
comparison with other producing properties, the assumed effects of regulation by
governmental agencies and assumptions concerning future operating costs,
severance and excise taxes, export tariffs, abandonment costs, development costs
and workover and remedial costs, all of which may vary considerably from actual
results. All such estimates are to some degree speculative, and various
classifications of reserves are only attempts to define the degree of
speculation involved. For these reasons, estimates of the commercially
recoverable reserves of oil attributable to any particular property or group of
properties, the classification, cost and risk of recovering such reserves and
estimates of the future net cash flows expected therefrom, prepared by different
engineers or by the same engineers at different times, may vary substantially.
The difficulty of making precise estimates is accentuated by the fact that 65%
of the Company's total proved reserves were non-producing as of December 31,
1995. Therefore, the Company's actual production, revenues, severance and excise
taxes, export tariffs, development expenditures, workover and remedial
expenditures, abandonment expenditures and operating expenditures with respect
to its reserves will likely vary from estimates, and such variances may be
material.
 
In addition, actual future net cash flows will be affected by factors such as
actual production, supply and demand for oil, availability and capacity of
gathering systems and pipelines, changes in governmental regulations or taxation
and the impact of inflation on costs. The timing of actual future net revenue
from proved reserves, and thus their actual present value, can be affected by
the timing of the incurrence of expenditures in connection with development of
oil and gas properties. The 10% discount factor, which is required by the
Commission to be used to calculate present value for reporting purposes, is not
necessarily the most appropriate discount factor based on interest rates in
effect from time to time and risks associated with the oil and gas industry.
Discounted present value, no matter what discount rate is used, is materially
affected by assumptions as to the amount and timing of future production, which
may and often do prove to be inaccurate.

REGULATION
 
General
The Company's operations are affected by political developments and laws and
regulations in the areas in which it operates. In particular, oil and gas
production operations and economics are affected by price controls, tax and
other laws relating to the petroleum industry, by changes in such laws and by
changing administrative regulations and the interpretations and application of
such rules and regulations. In addition, various federal, state, local and
international laws and regulations covering the discharge of materials into the
environment, the disposal of oil and gas wastes, or otherwise relating to the
protection of the environment, may affect the Company's operations and costs.
Oil and gas industry legislation and agency regulation is periodically changed
for a variety of political, economic, environmental and other reasons. Numerous
governmental departments and agencies issue rules and regulations binding on the
oil and gas industry, some of which carry substantial penalties for the failure
to comply. The regulatory burden on the oil and gas industry increases the
Company's cost of doing business.
 
Venezuela
Venezuela requires environmental and other permits for certain operations
conducted in oil field development, such as site construction, drilling, and
seismic activities. As a contractor to Lagoven, Benton-Vinccler submits capital
and operating budgets to Lagoven for approval. Capital expenditures to comply
with Venezuelan environmental regulations relating to the reinjection of gas in
the field and water disposal are expected to approximate $7.8 million in 1996
and $14.4 million in 1997, respectively. Benton-Vinccler also submits requests
for permits for drilling, seismic and operating activities to Lagoven, which
then obtains such permits from the Ministry of Energy and Mines and Ministry of

    oil wells, of which 11 gross (4.781 net) were completed as producers, and
    one gross (.435 net) gas well, which was completed as a producer. In March
    1995, the Company sold certain of its interests in the field, a result of
    which was to substantially eliminate the Company's future participation in
    recompletion and redrilling activities and in April 1996, the Company sold
    the remainder of its interests in the field. See "-- Other Properties."
 
(2) In addition to the activities set forth in the table, the Company
    participated in the successful recompletion of five gross (4.0 net) oil
    wells in Venezuela during the year ended December 31, 1994. The Company
    participated in the successful reactivation of nine gross (4.5 net) oil
    wells in Venezuela during the year ended December 31, 1993.
 
(3) In addition to the activities set forth in the table, the Company
    participated in the successful reactivation of one gross (.34 net) oil well
    in Russia during the year ended December 31, 1995. The Company participated
    in the successful reactivation of six gross (2.04 net) oil wells in Russia
    during the year ended December 31, 1994. The Company participated in the
    successful reactivation of four gross (1.36 net) oil wells in Russia during
    the year ended December 31, 1993.
 
(4) The information related to producing wells reflects wells the Company
    drilled, wells the Company participated in drilling and producing wells the
    Company acquired.
 
At December 31, 1995, the Company was participating in the drilling of 2 wells
in Venezuela, and 4 wells in Russia.
 
All of the Company's drilling activities are conducted on a contract basis with
independent drilling contractors. The Company does not own any drilling
equipment.
 
From commencement of operations through December 31, 1995, the Company added,
net of production and property sales, approximately 96,180 MBOE of proved
reserves through purchases of reserves-in-place, discoveries of oil and natural
gas reserves, extensions of existing producing fields and revisions of
previously estimated reserves. The Company's finding and development costs for
its proved reserves from inception to December 31, 1995 were $1.75 per BOE. The
Company's estimate of future development costs for its undeveloped proved
reserves at December 31, 1995 was $1.80 per BOE. The estimated future
development costs are based upon the Company's anticipated cost of developing
its non-producing proved reserves, which costs are calculated using historical
costs for similar activities.

    positions. The table excludes the acreage sold. See "-- Other Properties."
 
COMPETITION
 
The Company encounters strong competition from major oil and gas companies and
independent operators in acquiring properties and leases for exploration for
crude oil and natural gas. The principal competitive factors in the acquisition
of such oil and gas properties include the staff and data necessary to identify,
investigate and purchase such leases, and the financial resources necessary to
acquire and develop such leases. Many of the Company's competitors have
financial resources, staffs and facilities substantially greater than those of
the Company.
 
EMPLOYEES AND CONSULTANTS
 
At December 31, 1995, the Company had 43 employees and one independent
consultant. Benton-Vinccler had 109 employees and GEOILBENT had 220 employees.
 
TITLE TO DEVELOPED AND UNDEVELOPED ACREAGE
 
All Venezuelan reserves are attributable to an operating service agreement
between Benton-Vinccler and Lagoven, under which all mineral rights are owned by
the Government of Venezuela. With regard to Russian acreage, GEOILBENT has
obtained certain documentation from appropriate regulatory bodies in Russia
which the Company believes is adequate to establish GEOILBENT's right to
develop, produce and market oil and gas from the North Gubkinskoye Field in
Russia.
 
At the time of acquisition of undeveloped acreage in the United States, the
Company conducted a limited title investigation. A title opinion from a
qualified law firm was obtained prior to drilling any given U.S. prospect. Title
to presently producing properties had been investigated by a qualified law firm
prior to purchase. The Company believes its method of investigating the title to
these domestic properties was consistent with general practices in the oil and
gas industry and was designed to enable the Company to acquire title which was
generally considered to be acceptable in the oil and gas industry.
 
LEGAL PROCEEDINGS
 
On June 13, 1994, Charles Agnew and other limited partners in several limited
partnerships formed by the Company brought an action in the Superior Court of
California, County of Ventura, against the Company for alleged actions and
omissions of the Company in operating the partnerships and alleged
misrepresentations made by the Company in selling the limited partnership
interests. The claimants seek an unspecified amount of actual and punitive
damages. On May 17, 1995, the Company agreed to a binding arbitration proceeding
with respect to such claims, which is currently in the discovery stage. The
Company will be forced to spend time and financial resources to defend or
resolve these matters. In January 1996, the Company acquired all of the
interests in three of the limited partnerships which are the subject of the
arbitration, in exchange for shares of, and warrants to purchase shares of, the
Company's common stock. In the arbitration proceeding, if any liability is found
to exist, the arbitrator will determine the amount of any damages, and may
consider all distributions made to the partners, including the consideration
received in the exchange offer, in determining the extent of damages, if any.
However, there can be no assurance that an arbitrator will consider such factors
in his or her determination of damages if the allegations are found to be true
and damages are awarded.
 
The Company is also subject to ordinary litigation that is incidental to its
business.

                               THE EXCHANGE OFFER
    
 
   
PURPOSE OF THE EXCHANGE OFFER
    
 
   
In connection with the sale of the Old Notes, the Company entered into the
Registration Rights Agreement with the Initial Purchaser, pursuant to which the
Company agreed to use its best efforts to file with the Commission a
registration statement with respect to the exchange of the Old Notes for debt
securities with terms identical in all material respects to the terms of the Old
Notes, except that (i) the offer and sale of the New Notes have been registered
under the Securities Act and therefore the New Notes will not be subject to
certain restrictions on transfer applicable to the Old Notes, will not contain
certain legends relating thereto and will not be entitled to registration and
other rights under the Registration Rights Agreement, and (ii) the New Notes
will not provide for any increase in the interest rate thereon. In that regard,
the Old Notes provide, among other things, that, if the Exchange Offer is not
consummated by August 31, 1996, the interest rate borne by the Old Notes from
May 1, 1996 will increase by 0.50% per annum until the Exchange Offer is
consummated. Upon consummation of the Exchange Offer, holders of Old Notes will
not be entitled to any increase in the rate of interest thereon or any further
registration rights under the Registration Rights Agreement. See
"Summary -- Certain Consequences of a Failure to Exchange Old Notes" and
"Description of the Old Notes."
    
 
The Exchange Offer is not being made to, nor will the Company accept tenders for
exchange from, holders of Old Notes in any jurisdiction in which the Exchange
Offer or the acceptance thereof would not be in compliance with the securities
or blue sky laws of such jurisdiction.
 
   
TERMS OF THE EXCHANGE
    
 
   
The Company hereby offers, upon the terms and subject to the conditions set
forth in this Prospectus and in the accompanying Letter of Transmittal, to
exchange up to $125 million aggregate principal amount of New Notes for a like
aggregate principal amount of Old Notes properly tendered on or prior to the
Expiration Date (as defined below) and not properly withdrawn in accordance with
the procedures described below. The Company will issue, promptly after the
Expiration Date, an aggregate principal amount of up to $125 million of New
Notes in exchange for a like principal amount of outstanding Old Notes tendered
and accepted in connection with the Exchange Offer.
    
 
   
The Exchange Offer is not conditioned upon any minimum principal amount of Old
Notes being tendered. As of the date of this Prospectus $125 million aggregate
principal amount of Old Notes is outstanding.
    
 
Holders of Old Notes do not have any appraisal or dissenters' rights in
connection with the Exchange Offer. Old Notes which are not tendered for
exchange or are tendered but not accepted in connection with the Exchange Offer
will remain outstanding and be entitled to the benefits of the Indenture, but
will not be entitled to any further registration rights under the Registration
Rights Agreement.
 
If any tendered Old Notes are not accepted for exchange because of an invalid
tender, the occurrence of certain other events set forth herein or otherwise,
certificates for any such unaccepted Old Notes will be returned, without
expense, to the tendering holder thereof promptly after the Expiration Date.
 
Holders who tender Old Notes in connection with the Exchange Offer will not be
required to pay brokerage commissions or fees or, subject to the instructions in
the Letter of Transmittal, transfer taxes with respect to the exchange of Old
Notes in connection with the Exchange Offer. The Company will pay all charges
and expenses, other than certain applicable taxes described below, in connection
with the Exchange Offer. See " -- Fees and Expenses."
 
NEITHER THE BOARD OF DIRECTORS OF THE COMPANY NOR THE COMPANY MAKES ANY
RECOMMENDATION TO HOLDERS OF OLD NOTES AS TO WHETHER TO TENDER OR REFRAIN FROM
TENDERING ALL OR ANY PORTION OF THEIR OLD NOTES PURSUANT TO THE EXCHANGE OFFER.
IN ADDITION, NO ONE HAS BEEN AUTHORIZED TO MAKE ANY SUCH RECOMMENDATION. HOLDERS
OF OLD NOTES MUST MAKE THEIR OWN DECISION WHETHER TO TENDER PURSUANT TO THE
EXCHANGE OFFER AND, IF SO, THE AGGREGATE AMOUNT OF OLD NOTES TO TENDER AFTER
READING THIS PROSPECTUS AND THE LETTER OF TRANSMITTAL AND CONSULTING WITH THEIR
ADVISERS, IF ANY, BASED ON THEIR OWN FINANCIAL POSITION AND REQUIREMENTS.

<PAGE>   45
 
   
EXPIRATION DATE; EXTENSIONS; AMENDMENTS
    
 
   
The term "Expiration Date" means 5:00 p.m., New York City time, on August 23,
1996 unless the Exchange Offer is extended by the Company (in which case the
term "Expiration Date" shall mean the latest date and time to which the Exchange
Offer is extended).
    
 
The Company expressly reserves the right in its sole and absolute discretion,
subject to applicable law, at any time and from time to time, (i) to delay the
acceptance of the Old Notes for exchange, (ii) to terminate the Exchange Offer
(whether or not any Old Notes have theretofore been accepted for exchange) if
the Company determines, in its sole and absolute discretion, that any of the
events or conditions referred to under "-- Certain Conditions to the Exchange
Offer" have occurred or exist or have not been satisfied, (iii) to extend the
Expiration Date of the Exchange Offer and retain all Old Notes tendered pursuant
to the Exchange Offer, subject, however, to the right of holders of Old Notes to
withdraw their tendered Old Notes as described under "-- Withdrawal Rights," and
(iv) to waive any condition or otherwise amend the terms of the Exchange Offer
in any respect. If the Exchange Offer is amended in a manner determined by the
Company to constitute a material change, or if the Company waives a material
condition of the Exchange Offer, the Company will promptly disclose such
amendment by means of a prospectus supplement that will be distributed to the
registered holders of the Old Notes, and the Company will extend the Exchange
Offer to the extent required by Rule 14e-1 under the Exchange Act.
 
Any such delay in acceptance, extension, termination or amendment will be
followed promptly by oral or written notice thereof to the Exchange Agent and by
making a public announcement thereof, and such announcement in the case of an
extension will be made no later than 9:00 a.m., New York City time, on the next
business day after the previously scheduled Expiration Date. Without limiting
the manner in which the Company may choose to make any public announcement and
subject to applicable law, 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.
 
   
ACCEPTANCE FOR EXCHANGE AND ISSUANCE OF NEW NOTES
    
 
Upon the terms and subject to the conditions of the Exchange Offer, the Company
will exchange, and will issue to the Exchange Agent, New Notes for Old Notes
validly tendered and not withdrawn (pursuant to the withdrawal rights described
under "-- Withdrawal Rights") promptly after the Expiration Date.
 
In all cases, delivery of New Notes in exchange for Old Notes tendered and
accepted for exchange pursuant to the Exchange Offer will be made only after
timely receipt by the Exchange Agent of (i) Old Notes or a book-entry
confirmation of a book-entry transfer of Old Notes into the Exchange Agent's
account at The Depositary Trust Company ("DTC"), (ii) the Letter of Transmittal
(or facsimile thereof), properly completed and duly executed, with any required
signature guarantees, and (iii) any other documents required by the Letter of
Transmittal.
 
The term "book-entry confirmation" means a timely confirmation of a book-entry
transfer of Old Notes into the Exchange Agent's account at DTC.
 
Subject to the terms and conditions of the Exchange Offer, the Company will be
deemed to have accepted for exchange, and thereby exchanged, Old Notes validly
tendered and not withdrawn as, if and when the Company gives oral or written
notice to the Exchange Agent of the Company's acceptance of such Old Notes for
exchange pursuant to the Exchange Offer. The Exchange Agent will act as agent
for the Company for the purpose of receiving tenders of Old Notes, Letters of
Transmittal and related documents, and as agent for tendering holders for the
purpose of receiving Old Notes, Letters of Transmittal and related documents and
transmitting New Notes to validly tendering holders. Such exchange will be made
promptly after the Expiration Date. If for any reason whatsoever, acceptance for
exchange or the exchange of any Old Notes tendered pursuant to the Exchange
Offer is delayed (whether before or after the Company's acceptance for exchange
of Old Notes) or the Company extends the Exchange Offer or is unable to accept
for exchange or exchange Old Notes tendered pursuant to the Exchange Offer,
then, without prejudice to the Company's rights set forth herein, the Exchange
Agent may, nevertheless, on behalf of the Company and subject to Rule 14e-1(c)
under the Exchange Act, retain tendered Old Notes and such Old Notes may not be
withdrawn except to the extent tendering holders are entitled to withdrawal
rights as described under "-- Withdrawal Rights."
 
Pursuant to the Letter of Transmittal, a holder of Old Notes will warrant and
agree in the Letter of Transmittal that it has full power and authority to
tender, exchange, sell, assign and transfer Old Notes, that the Company will
acquire good, marketable and unencumbered title to the tendered Old Notes, free
and clear of all liens, restrictions, charges and encumbrances, and the Old
Notes tendered for exchange are not subject to any adverse claims or proxies.
The holder also will warrant and agree that it will, upon request, execute and
deliver any additional documents deemed by the Company or the Exchange Agent to
be necessary or desirable to complete the exchange, sale, assignment, and
transfer of the Old Notes tendered pursuant to the Exchange Offer.

<PAGE>   46
 
   
PROCEDURES FOR TENDERING OLD NOTES
    
 
   
Valid Tender.  Except as set forth below, in order for Old Notes to be validly
tendered pursuant to the Exchange Offer, a properly completed and duly executed
Letter of Transmittal (or facsimile thereof), with any required signature
guarantees and any other required documents, must be received by the Exchange
Agent at one of its addresses set forth under "-- Exchange Agent," and either
(i) tendered Old Notes must be received by the Exchange Agent, or (ii) such Old
Notes must be tendered pursuant to the procedures for book-entry transfer set
forth below and a book-entry confirmation must be received by the Exchange
Agent, in each case on or prior to the Expiration Date, or (iii) the guaranteed
delivery procedures set forth below must be complied with.
    
 
If less than all of the Old Notes are tendered, a tendering holder should fill
in the amount of Old Notes being tendered in the appropriate box on the Letter
of Transmittal. The entire amount of Old Notes delivered to the Exchange Agent
will be deemed to have been tendered unless otherwise indicated.
 
THE METHOD OF DELIVERY OF CERTIFICATES, THE LETTER OF TRANSMITTAL AND ALL OTHER
REQUIRED DOCUMENTS, IS AT THE OPTION AND SOLE RISK OF THE TENDERING HOLDER, AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE EXCHANGE AGENT.
IF DELIVERY IS BY MAIL, REGISTERED MAIL, RETURN RECEIPT REQUESTED, PROPERLY
INSURED, OR AN OVERNIGHT DELIVERY SERVICE IS RECOMMENDED. IN ALL CASES,
SUFFICIENT TIME SHOULD BE ALLOWED TO ENSURE TIMELY DELIVERY.
 
   
Book-Entry Transfer.  The Exchange Agent will establish an account with respect
to the Old Notes at DTC for purposes of the Exchange Offer within two business
days after the date of this Prospectus. Any financial institution that is a
participant in DTC's book-entry transfer facility system may make a book-entry
delivery of the Old Notes by causing DTC to transfer such Old Notes into the
Exchange Agent's account at DTC in accordance with DTC's procedures for
transfers. However, although delivery of Old Notes may be effected through
book-entry transfer into the Exchange Agent's account at DTC, the Letter of
Transmittal (or facsimile thereof), properly completed and duly executed, with
any required signature guarantees and any other required documents, must in any
case be delivered to and received by the Exchange Agent at its address set forth
under "-- Exchange Agent" on or prior to the Expiration Date, or the guaranteed
delivery procedure set forth below must be complied with.
    
 
   
DELIVERY OF DOCUMENTS TO DTC IN ACCORDANCE WITH DTC'S PROCEDURES DOES NOT
CONSTITUTE DELIVERY TO THE EXCHANGE AGENT.
    
 
   
Signature Guarantees.  Certificates for the Old Notes need not be endorsed and
signature guarantees on the Letter of Transmittal are unnecessary unless (a) a
certificate for the Old Notes is registered in a name other than that of the
person surrendering the certificate or (b) such registered holder completes the
box entitled "Special Issuance Instructions" or "Special Delivery Instructions"
in the Letter of Transmittal. In the case of (a) or (b) above, such certificates
for Old Notes must be duly endorsed or accompanied by a properly executed bond
power, with the endorsement or signature on the bond power and on the Letter of
Transmittal guaranteed by a firm or other entity identified in Rule 17Ad-15
under the Exchange Act as an "eligible guarantor institution," including (as
such terms are defined therein): (i) a bank; (ii) a broker, dealer, municipal
securities broker or dealer or government securities broker or dealer; (iii) a
credit union; (iv) a national securities exchange, registered securities
association or clearing agency; or (v) a savings association that is a
participant in a Securities Transfer Association (an "Eligible Institution"),
unless surrendered on behalf of such Eligible Institution. See Instruction 1 to
the Letter of Transmittal.
    
 
   
Guaranteed Delivery.  If a holder desires to tender Old Notes pursuant to the
Exchange Offer and the certificates for such Old Notes are not immediately
available or time will not permit all required documents to reach the Exchange
Agent on or before the Expiration Date, or the procedures for book-entry
transfer cannot be completed on a timely basis, such Old Notes may nevertheless
be tendered, provided that all of the following guaranteed delivery procedures
are complied with:
    
 
(i) such tenders are made by or through an Eligible Institution;
 
(ii) a properly completed and duly executed Notice of Guaranteed Delivery,
substantially in the form accompanying the Letter of Transmittal, is received by
the Exchange Agent, as provided below, on or prior to the Expiration Date; and
 
(iii) the certificates (or a book-entry confirmation) representing all tendered
Old Notes, in proper form for transfer, together with a properly completed and
duly executed Letter of Transmittal (or facsimile thereof), with any required
signature guarantees and any other documents required by the Letter of
Transmittal, are received by the Exchange Agent within three New York Stock
Exchange trading days after the date of execution of such Notice of Guaranteed
Delivery.
 
                                       46
<PAGE>   47
 
The Notice of Guaranteed Delivery may be delivered by hand, or transmitted by
facsimile or mail to the Exchange Agent and must include a guarantee by an
Eligible Institution in the form set forth in such notice.
 
Notwithstanding any other provision hereof, the delivery of New Notes in
exchange for Old Notes tendered and accepted for exchange pursuant to the
Exchange Offer will in all cases be made only after timely receipt by the
Exchange Agent of Old Notes, or of a book-entry confirmation with respect to
such Old Notes, and a properly completed and duly executed Letter of Transmittal
(or facsimile thereof), together with any required signature guarantees and any
other documents required by the Letter of Transmittal. Accordingly, the delivery
of New Notes might not be made to all tendering holders at the same time, and
will depend upon when Old Notes, book-entry confirmations with respect to Old
Notes and other required documents are received by the Exchange Agent.
 
The Company's acceptance for exchange of Old Notes tendered pursuant to any of
the procedures described above will constitute a binding agreement between the
tendering holder and the Company upon the terms and subject to the conditions of
the Exchange Offer.
 
   
Determination of Validity.  All questions as to the form of documents, validity,
eligibility (including time of receipt) and acceptance for exchange of any
tendered Old Notes will be determined by the Company, in its sole discretion,
whose determination shall be final and binding on all parties. The Company
reserves the absolute right, in its sole and absolute discretion, to reject any
and all tenders determined by it not to be in proper form or the acceptance of
which, or exchange for, may, in the view of counsel to the Company, be unlawful.
The Company also reserves the absolute right, subject to applicable law, to
waive any of the conditions of the Exchange Offer as set forth under "-- Certain
Conditions to the Exchange Offer" or any condition or irregularity in any tender
of Old Notes of any particular holder whether or not similar conditions or
irregularities are waived in the case of other holders.
    
 
The Company's interpretation of the terms and conditions of the Exchange Offer
(including the Letter of Transmittal and the instructions thereto) will be final
and binding. No tender of Old Notes will be deemed to have been validly made
until all irregularities with respect to such tender have been cured or waived.
Neither the Company, any affiliates or assigns of the Company, the Exchange
Agent nor any other person shall be under any duty to give any notification of
any irregularities in tenders or incur any liability for failure to give any
such notification.
 
   
If any Letter of Transmittal, endorsement, bond power, power of attorney, or any
other document required by the Letter of Transmittal is signed by a trustee,
executor, administrator, guardian, attorney-in-fact, officer of a corporation or
other person acting in a fiduciary or representative capacity, such person
should so indicate when signing, and unless waived by the Company, proper
evidence satisfactory to the Company, in its sole discretion, of such person's
authority to so act must be submitted.
    
 
A beneficial owner of Old Notes that are held by or registered in the name of a
broker, dealer, commercial bank, trust company or other nominee or custodian is
urged to contact such entity promptly if such beneficial holder wishes to
participate in the Exchange Offer.
 
   
RESALES OF NEW NOTES
    
 
The Company is making the Exchange Offer in reliance on the position of the
staff of the Division of Corporation Finance of the Commission as set forth in
certain interpretive letters addressed to third parties in other transactions.
However, the Company has not sought its own interpretive letter and there can be
no assurance that the staff of the Division of Corporation Finance of the
Commission would make a similar determination with respect to the Exchange Offer
as it has in such interpretive letters to third parties. Based on these
interpretations by the staff of the Division of Corporation Finance, and subject
to the two immediately following sentences, the Company believes that New Notes
issued pursuant to this Exchange Offer in exchange for Old Notes may be offered
for resale, resold and otherwise transferred by a holder thereof (other than a
holder who is a broker-dealer) without further compliance with the registration
and prospectus delivery requirements of the Securities Act, provided that such
New Notes are acquired in the ordinary course of such holder's business and that
such holder is not participating, and has no arrangement or understanding with
any person to participate, in a distribution (within the meaning of the
Securities Act) of such New Notes. However, any holder of Old Notes who is an
"affiliate" of the Company or who intends to participate in the Exchange Offer
for the purpose of distributing New Notes, or any broker-dealer who purchased
Old Notes from the Company to resell pursuant to Rule 144A or any other
available exemption under the Securities Act, (a) will not be able to rely on
the interpretations of the staff of the Division of Corporation Finance of the
Commission set forth in the above-mentioned interpretive letters, (b) will not
be permitted or entitled to tender such Old Notes in the Exchange Offer and (c)
must comply with the registration and prospectus delivery requirements of the
Securities Act in connection with any sale or other transfer of such Old Notes
unless such sale is made pursuant to an exemption from such requirements. In
addition, as described below, if any broker-dealer holds Old Notes acquired for
its own account as a result of market-making or other trading activities and
exchanges
 
                                       47
<PAGE>   48
 
such Old Notes for New Notes, then such broker-dealer must deliver a prospectus
meeting the requirements of the Securities Act in connection with any resales of
such New Notes.
 
Each holder of Old Notes who wishes to exchange Old Notes for New Notes in the
Exchange Offer will be required to represent that (i) it is not an "affiliate"
of the Company, (ii) any New Notes to be received by it are being acquired in
the ordinary course of its business, (iii) it has no arrangement or
understanding with any person to participate in a distribution (within the
meaning of the Securities Act) of such New Notes, and (iv) if such holder is not
a broker-dealer, such holder is not engaged in, and does not intend to engage
in, a distribution (within the meaning of the Securities Act) of such New Notes.
Each broker-dealer that receives New Notes for its own account pursuant to the
Exchange Offer must acknowledge that it acquired the Old Notes for its own
account as the result of market-making activities or other trading activities
and must agree that it will deliver a prospectus meeting the requirements of the
Securities Act in connection with any resale of such New Notes. The Letter of
Transmittal states that by so acknowledging and by delivering a prospectus, a
broker-dealer will not be deemed to admit that it is an "underwriter" within the
meaning of the Securities Act. Based on the position taken by the staff of the
Division of Corporation Finance of the Commission in the interpretive letters
referred to above, the Company believes that broker-dealers who acquired Old
Notes for their own accounts as a result of market-making activities or other
trading activities ("Participating Broker-Dealers") may fulfill their prospectus
delivery requirements with respect to the New Notes received upon exchange of
such Old Notes (other than Old Notes which represent an unsold allotment from
the original sale of the Old Notes) with a prospectus meeting the requirements
of the Securities Act, which may be the prospectus prepared for an exchange
offer so long as it contains a description of the plan of distribution with
respect to the resale of such New Notes. Accordingly, this Prospectus, as it may
be amended or supplemented from time to time, may be used by a Participating
Broker-Dealer during the period referred to below in connection with resales of
New Notes received in exchange for Old Notes where such Old Notes were acquired
by such Participating Broker-Dealer for its own account as a result of
market-making or other trading activities.
 
   
Subject to certain provisions set forth in the Registration Rights Agreement,
the Company has agreed that this Prospectus, as it may be amended or
supplemented from time to time, may be used by a Participating Broker-Dealer in
connection with resales of such New Notes for a period ending 180 days after the
Expiration Date (subject to extension under certain limited circumstances
described below) or, if earlier, when all such New Notes have been disposed of
by such Participating Broker-Dealer. See "Plan of Distribution." Any
Participating Broker-Dealer who is an "affiliate" of the Company may not rely on
such interpretive letters and must comply with the registration and prospectus
delivery requirements of the Securities Act in connection with any resale
transaction.
    
 
   
In that regard, each Participating Broker-Dealer who surrenders Old Notes
pursuant to the Exchange Offer will be deemed to have agreed, by execution of
the Letter of Transmittal, that, upon receipt of notice from the Company of the
occurrence of any event or the discovery of any fact which makes any statement
contained or incorporated by reference in this Prospectus untrue in any material
respect or which causes this Prospectus to omit to state a material fact
necessary in order to make the statements contained or incorporated by reference
herein, in light of the circumstances under which they were made, not misleading
or of the occurrence of certain other events specified in the Registration
Rights Agreement, such Participating Broker-Dealer will suspend the sale of New
Notes pursuant to this Prospectus until the Company has amended or supplemented
this Prospectus to correct such misstatement or omission and has furnished
copies of the amended or supplemented Prospectus to such Participating
Broker-Dealer or the Company has given notice that the sale of the New Notes may
be resumed, as the case may be. If the Company gives such notice to suspend the
sale of the New Notes, it shall extend the 180-day period referred to above
during which Participating Broker-Dealers are entitled to use this Prospectus in
connection with the resale of New Notes by the number of days during the period
from and including the date of the giving of such notice to and including the
date when Participating Broker-Dealers shall have received copies of the amended
or supplemented Prospectus necessary to permit resales of the New Notes or to
and including the date on which the Company has given notice that the sale of
New Notes may be resumed, as the case may be.
    
 
   
WITHDRAWAL RIGHTS
    
 
Except as otherwise provided herein, tenders of Old Notes may be withdrawn at
any time on or prior to the Expiration Date.
 
In order for a withdrawal to be effective a written, telegraphic, telex or
facsimile transmission of such notice of withdrawal must be timely received by
the Exchange Agent at one of its addresses set forth under "-- Exchange Agent"
on or prior to the Expiration Date. Any such notice of withdrawal must specify
the name of the person who tendered the Old Notes to be withdrawn, the aggregate
principal amount of Old Notes to be withdrawn, and (if certificates for such Old
Notes have been tendered) the name of the registered holder of the Old Notes as
set forth on the Old Notes, if different from that of the person who tendered
such Old Notes. If Old Notes have been delivered or otherwise identified to the
Exchange Agent, then prior to the physical release of such Old Notes, the
tendering holder must submit the serial numbers shown on the particular Old
Notes to be withdrawn and the
 
                                       48
<PAGE>   49
 
   
signature on the notice of withdrawal must be guaranteed by an Eligible
Institution, except in the case of Old Notes tendered for the account of an
Eligible Institution. If Old Notes have been tendered pursuant to the procedures
for book-entry transfer set forth in "-- Procedures for Tendering Old Notes,"
the notice of withdrawal must specify the name and number of the account at DTC
to be credited with the withdrawal of Old Notes, in which case a notice of
withdrawal will be effective if delivered to the Exchange Agent by written,
telegraphic, telex or facsimile transmission. Withdrawals of tenders of Old
Notes may not be rescinded. Old Notes properly withdrawn will not be deemed
validly tendered for purposes of the Exchange Offer, but may be retendered at
any subsequent time on or prior to the Expiration Date by following any of the
procedures described above under "-- Procedures for Tendering Old Notes."
    
 
All questions as to the validity, form and eligibility (including time of
receipt) of such withdrawal notices will be determined by the Company, in its
sole discretion, whose determination shall be final and binding on all parties.
Neither the Company, any affiliates or assigns of the Company, the Exchange
Agent nor any other person shall be under any duty to give any notification of
any irregularities in any notice of withdrawal or incur any liability for
failure to give any such notification. Any Old Notes which have been tendered
but which are withdrawn will be returned to the holder thereof promptly after
withdrawal.
 
   
INTEREST ON THE NEW NOTES
    
 
   
Each New Note will bear interest at the rate of 11 5/8% per annum from the most
recent date to which interest has been paid or duly provided for on the Old Note
surrendered in exchange for such New Note or, if no interest has been paid or
duly provided for on such Old Note, from May 1, 1996. Interest on the New Notes
will be payable semiannually on May 1 and November 1 of each year, commencing on
the first such date following the original issuance date of the New Notes.
    
 
Holders of Old Notes whose Old Notes are accepted for exchange will not receive
accrued interest on such Old Notes for any period from and after the last
Interest Payment Date to which interest has been paid or duly provided for on
such Old Notes prior to the original issue date of the New Notes or, if no such
interest has been paid or duly provided for, will not receive any accrued
interest on such Old Notes, and will be deemed to have waived the right to
receive any interest on such Old Notes accrued from and after such Interest
Payment Date or, if no such interest has been paid or duly provided for, from
and after May 1, 1996.
 
   
CERTAIN CONDITIONS TO THE EXCHANGE OFFER
    
 
Notwithstanding any other provisions of the Exchange Offer, or any extension of
the Exchange Offer, the Company will not be required to accept for exchange, or
to exchange, any Old Notes for any New Notes, and, as described below, may
terminate the Exchange Offer (whether or not any Old Notes have theretofore been
accepted for exchange) or may waive any conditions to or amend the Exchange
Offer, if any of the following conditions have occurred or exists or have not
been satisfied:
 
(a) the Exchange Offer, or the making of any exchange by a holder, violates any
applicable law or any applicable interpretation of the staff of the Commission;
 
(b) any action or proceeding shall have been instituted or threatened in any
court or by or before any governmental agency or body with respect to the
Exchange Offer which, in the Company's judgment, would reasonably be expected to

(c) any law, statute, rule or regulation shall have been adopted or enacted
which, in the Company's judgment, would reasonably be expected to impair the

The Company has agreed to pay the Exchange Agent reasonable and customary fees
for its services and will reimburse it for its reasonable out-of-pocket expenses
in connection therewith. The Company will also pay brokerage houses and other

Offer, then the amount of any such transfer taxes (whether imposed on the
registered holder or any other persons) will be payable by the tendering holder.
If satisfactory evidence of payment of such taxes or exemption therefrom is not
submitted with the Letter of Transmittal, the amount of such transfer taxes will
be billed directly to such tendering holder.
 
The Company will not make any payment to brokers, dealers or others soliciting
acceptances of the Exchange Offer.
 
   
                    DESCRIPTION OF OUTSTANDING INDEBTEDNESS
    
 
   
The summaries contained herein of certain provisions of the indebtedness of the
Company do not purport to be complete and, except in the case of the short term
debt, are qualified in their entirety by the provisions of the various
agreements and indentures related thereto.
    
 
   
CREDIT AGREEMENT
    
 
   
On May 30, 1996, the Company entered into a Credit Agreement with Morgan
Guaranty. The Credit Agreement provides for the issuance of a letter of credit
in the amount of $18,000,000 to be used to secure the Company's performance
under its agreements related to the development of the Delta Centro Block in
Venezuela. The letter of credit will be secured by cash collateral in the form
of a time deposit from the Company. Morgan Guaranty will receive an arrangement
fee and will receive a fee of .25% per annum computed on the daily average
maximum available amount of the letter of credit. In addition, the Credit
Agreement provides for a $20,000,000 unsecured revolving credit facility which
must be repaid on or before March 14, 1998. Borrowings under such facility
accrue interest at per annum rate equal to the sum of the Euro-Dollar margin
plus the Adjusted London Interbank Offered Rate for such interest period. The
Euro-Dollar margin will be 3% until September 14, 1997 and 3.75% per annum
thereafter. The revolving credit facility is secured by a guarantee by the
Company's subsidiary Benton-Vinccler, C.A. and a security interest in all
payments made to Benton-Vinccler, C.A. under its Service Agreement with Fagoven,
    
 
                                       50
<PAGE>   51
 
   
S.A. The Credit Agreement contains covenants and restrictions that are
substantially the same as those provided in the Indenture.
    
 
SHORT-TERM DEBT
 
   
The Company, through Benton-Vinccler, has entered into a six month loan
arrangement with Morgan Guaranty which has subsequently been renewed on a
monthly basis. Under such arrangement, Benton-Vinccler may borrow up to $25
million, $10 million of which may be borrowed on a revolving basis. Borrowings
under this loan arrangement are secured by cash collateral in the form of a time
deposit from the Company. The loan arrangement contains no restrictive covenants
and no financial ratio requirements. The principal amount of such loan
outstanding at March 31, 1996 was $19.3 million. Benton-Vinccler can borrow an
additional $5.7 million under the loan arrangement if the Company provides a
time deposit to secure such additional borrowings. Interest on borrowings under
the loan facility accrues, at the borrower's option, at either a fixed rate or a
floating rate. The borrower also has the option to change or continue the type
of interest rate borne by the loan. Floating rate borrowings (domestic loans)
accrue interest at the higher of Morgan Guaranty's prime rate or the sum of .50%
plus the Federal Funds Rate and may be prepaid at any time without penalty.
Fixed rate borrowings (Eurodollar loans) accrue interest at an adjusted LIBOR
rate plus a margin of .75%. A Eurodollar loan may not be repaid at the Company's
option on a date other than the last day of an interest period. Events of
default include failure to pay principal and interest when due, failure to pay
principal or interest on any other indebtedness of Benton-Vinccler or any of its
subsidiaries when due or upon acceleration thereof and insolvency of
Benton-Vinccler or any subsidiary thereof.
    
 
   
In October 1995, the Company and GEOILBENT entered into a loan arrangement with
Morgan Guaranty for working capital requirements. Under such arrangement,
GEOILBENT may borrow up to $10 million on a revolving basis. Borrowings under
this loan arrangement are secured by cash collateral in the form of a time
deposit by the Company. The loan arrangement contains no restrictive covenants
and no financial ratio requirements. The principal amount of such loan
outstanding at March 31, 1996 was $2.1 million.
    
 
8% CONVERTIBLE SUBORDINATED DEBENTURES DUE MAY 1, 2002
 
   
In May 1992, the Company issued $6,428,000 principal amount of publicly offered
8% Convertible Subordinated Debentures due May 1, 2002, convertible into Common
Stock at the option of the holder at any time prior to maturity at 101.157
shares per $1,000 principal amount of Debentures with interest payments due May
1 and November 1. On May 18, 1996 the Company called all of its outstanding
Debentures at a redemption price of 103% of the principal amount, together with
accrued interest, payable in cash. Prior to July 23, 1996, holders may elect to
convert their Debentures into Common Stock. As of June 4, 1996, approximately
55.4% of the outstanding Debentures have been converted into Common Stock,
resulting in the issuance of 263,283 shares of the Company's Common Stock.
    
 
The Indenture does not contain any restrictions on the payment of dividends, the
repurchase of any securities of the Company or any financial covenants nor does
the Indenture require any sinking fund or reserves for payment of the
Debentures. The Indenture does not contain any limitation on senior indebtedness
or any other indebtedness, secured or unsecured.
 
   
Events of default include failure to pay principal and interest when due, breach
of covenants, failure to pay principal of or interest on or any material
indebtedness of the Company when due or upon acceleration thereof and bankruptcy
or insolvency of the Company. At March 31, 1996, the aggregate principal amount
outstanding was $4.3 million.

                          DESCRIPTION OF THE NEW NOTES
    
 
GENERAL
 
   
The Old Notes were issued and the New Notes are to be issued pursuant to an
Indenture (the "Indenture") between the Company and First Trust of New York,
National Association, as trustee (the "Trustee") dated as of May 2, 1996. The
terms of the New Notes include those stated in the Indenture and those made part
of the Indenture by reference to the Trust Indenture Act of 1939, as amended
(the "Trust Indenture Act"). The Old Notes and New Notes are subject to all such
terms, and holders of Notes are referred to the Indenture and the Trust
Indenture Act for a statement thereof. A copy of the Indenture will be made
available to holders upon request. The following summary of certain provisions
of the Indenture does not purport to be complete and is qualified in its
entirety by reference to the Indenture including the definitions therein of
certain terms used below. The definitions of certain terms used in the following
summary are set forth below under "-- Certain Definitions" or are otherwise
defined in the Indenture.
    
 
   
The Old Notes and the New Notes will constitute a single series of debt
securities under the Indenture. If the Exchange Offer is consummated, holders of
the Old Notes who do not exchange their Old Notes for New Notes will vote
together with the holders of New Notes for all relevant purposes under the
Indenture. In that regard, the Indenture requires that certain actions by the
holders thereunder (including acceleration following an Event of Default) must
be taken, and certain rights must be exercised, by specified minimum percentages
of the aggregate principal amount of the outstanding debt securities. In
determining whether holders of the requisite percentage in principal amount have
given any notice, consent or waiver or taken any other action permitted under
the Indenture, any Old Notes which remain outstanding after the Exchange Offer
will be aggregated with the New Notes and the holders of such Old Notes and New
Notes will vote together as a single series for all such purposes. Accordingly,
all references herein to specified percentages in aggregate principal amount of
the outstanding Notes shall be deemed to mean, at any time after the Exchange
Offer is consummated, such percentage in aggregate principal amount of the Old
Notes and New Notes then outstanding.
    
 
   
The New Notes and the Old Notes are sometimes referred to as, collectively, the
"Notes" and, individually, a "Note."
    
 
   
The New Notes will mature on May 1, 2003, will be limited to $125 million
aggregate principal amount at maturity and will be unsecured senior debt
obligations of the Company. The principal amount at maturity of each New Note
will be $1,000 or any integral multiple thereof. The New Notes will be presented
for registration of transfer or exchange at the office of the registrar, which
initially will be the Trustee. No service charge will be made for any
registration of transfer or exchange of a New Note. However, the Company may
require payment by a holder of a sum sufficient to cover any tax or other
governmental charge payable in connection with the registration of such transfer
or exchange.
    
 
   
Interest on the New Notes will be payable semi-annually on May 1 and November 1
to holders of record on the close of business on the immediately preceding April
15 and October 15. Interest on the New Notes will accrue at the rate of 11 5/8%
per annum from the most recent date to which interest has been paid or duly
provided for on the Old Note surrendered in exchange for such New Note or, if no
interest has been paid or duly provided for on such Old Note, from May 1, 1996,
payable semianually on May 1 and November 1 of each year (each, an "Interest
Payment Date"), commencing with the first Interest Payment Date occurring after
the date of original issuance of such New Note, to the person in whose name such
New Note is registered at the close of business on the April 15 or October 15
next preceding such Interest Payment Date. Any overdue principal, premium, if
any, or interest will bear interest, to the extent lawful, at 13 5/8% per annum.
Interest will be computed on a basis of a 360-day year consisting of twelve
30-day months. Principal and interest will be payable at the office or agency of
the Company maintained for that purpose within the City and State of New York
or, at the option of the Company, payment of interest may be made by check
mailed to the holders of the New Notes. The New Notes will not provide for any
increase in the interest rate thereon. For a discussion for the circumstances
under which the interest rate on the Old Notes may be temporarily increased, see
"Description of the Old Notes."
    
 
RANKING
 
   
The New Notes will be senior unsecured debt obligations of the Company and will
rank senior in right of payment to all existing and future Subordinated
Indebtedness and pari passu with all other Senior Indebtedness.
    
 
   
The New Notes are obligations exclusively of the Company. Because the Company's
operations are conducted almost entirely through its Subsidiaries and joint
ventures, the cash flow and the consequent ability of the Company to service its
debt, including the New Notes and the Old Notes, are dependent upon the earnings
of the Company's Subsidiaries and joint ventures and the distribution of those
earnings to the Company. The Subsidiaries and joint ventures are separate and
distinct legal entities and have no obligation, contingent or otherwise, to pay
any amounts due pursuant to the Notes or to make funds available therefor,
    
 
                                       52
<PAGE>   53
 
whether by dividends, loans or other payments. In addition, the payment of
dividends and the making of loans and advances to the Company by its
Subsidiaries and joint ventures may be subject to statutory or contractual
restrictions and subject to various business considerations. Currently, the
Company only has one operating subsidiary, Benton-Vinccler, that may be expected
to make funds available to the Company to pay any amounts due pursuant to the
Notes.
 
   
The New Notes will be effectively subordinated to secured indebtedness of the
Company and all liabilities of the Company's Subsidiaries, including trade
payables and the liquidation value of Preferred Stock, if any, except to the
extent that the Company is itself recognized as a creditor of such Subsidiary,
in which case the claims of the Company would still be subordinate to any
security interest in the assets of such Subsidiary and any indebtedness of such
Subsidiary senior to that held by the Company. At March 31, 1996, after giving
pro forma effect to the U.S. Property Sale and the issuance of the Old Notes and
the use of proceeds received from each such transaction, $37.2 million of
consolidated indebtedness and trade payables would have been liabilities of the
Company's subsidiaries or secured indebtedness of the Company and ranked
effectively senior to the Notes and the Company would have had $6.4 million of
outstanding indebtedness and trade payables that would have ranked pari passu
with the Notes. In addition, the Company could have incurred up to $38.0 million
of secured indebtedness under its revolving letter of credit and loan facility
which would have ranked effectively senior to the Notes.
    
 
OPTIONAL REDEMPTION
 
   
Commencing May 1, 2000, the New Notes will be subject to redemption at the
option of the Company, in whole or in part, at any time and from time to time,
upon not less than 30 nor more than 60 days' notice, at the redemption prices
(expressed in percentages of the principal amount) set forth below plus accrued
and unpaid interest to the redemption date, if redeemed during the 12-month
period beginning on May 1 of the year indicated below:

                2001                                    102.906%
                2002                                    100.000%
</TABLE>
 
   
No sinking fund is provided for the New Notes.
    
 
At any time before May 1, 1999, the Company may also redeem up to 25% of the
aggregate principal amount of Notes then outstanding with the proceeds of a
public offering of Capital Stock (other than Disqualified Stock and a public
offering pursuant to a registration statement on Form S-8) of the Company within
90 days of such public offering at a redemption price equal to 111.625% of the
principal amount of such Notes, plus accrued and unpaid interest to the
redemption date; provided that at least $93.75 million in aggregate principal
amount of Notes remain outstanding immediately after giving effect to such
redemption.
 
If less than all the Notes are to be redeemed, the particular Notes or portions
thereof to be redeemed shall be selected by the Trustee from the outstanding
Notes not previously called for redemption, either pro rata, by lot or by any
other method the Trustee shall deem fair and reasonable, and the aggregate
principal amount to be redeemed must be equal to $1,000 or any integral multiple
thereof.
 
   
CERTAIN COVENANTS
    
 
The Indenture contains a number of covenants which restrict the ability of the
Company and its Restricted Subsidiaries to engage in certain activities. For
purposes of such covenants and the related definitions, the term Company shall
mean Benton Oil and Gas Company only, and shall not refer to any Subsidiary or
Affiliate of Benton Oil and Gas Company. In addition, whenever such covenants or
related definitions require any calculation of the income, interest expense,
discounted future net revenues attributable to proved oil and gas reserves or
other financial data of the Company or any Restricted Subsidiary, such
calculation shall, except to the extent that such covenants or definitions
provide to the contrary, exclude the income, interest expense, discounted future
net revenues attributable to proved oil and gas reserves or other financial data
of any Unrestricted Subsidiary or Affiliate of the Company (including GEOILBENT)
or such Restricted Subsidiary, as the case may be.
 
GEOILBENT, which is only 34%-owned by the Company, does not qualify as a
Subsidiary as defined in the Indenture and, consequently, the Indenture does not
restrict the Incurrence of Indebtedness by GEOILBENT. However, Indebtedness of
the Company and its Restricted Subsidiaries includes Indebtedness of any other
person, including GEOILBENT, to the extent that such Indebtedness is guaranteed
by, or secured by the assets of, the Company or any of its Restricted
Subsidiaries and, as a result, the Incurrence of any such guaranteed or secured
Indebtedness by GEOILBENT will, to the extent of the amount so guaranteed or
secured, be subject to the provisions of the Indenture described under
"Limitation on Indebtedness." In the event of any liquidation of GEOILBENT, the
claims of GEOILBENT's creditors would have to be satisfied prior to the
Company's receiving any distributions with respect to its 34% ownership interest
in GEOILBENT.
 
                                       53
<PAGE>   54
 
The Indenture contains, among others, the following covenants:
 
Limitation on Indebtedness.  The Company will not, and will not permit any of
its Restricted Subsidiaries to, Incur any Indebtedness (including any Acquired
Indebtedness) unless (i) no Default or Event of Default under the Indenture
shall have occurred and be continuing at the time or as a consequence of the
Incurrence of such Indebtedness, (ii) after giving effect thereto (including, in
connection with any acquisition being financed through the Incurrence of such
Indebtedness, any Acquired Indebtedness and any proved oil and gas reserves
being acquired in connection therewith) the EBITDA/Interest Ratio would be
greater than 3.0 to 1.0, (iii) in the event such Indebtedness would be Incurred
by the Company but would not be Permitted Company Secured Indebtedness, such
Indebtedness would have an Average Life greater than the Average Life of the
Notes and a stated maturity later than the Stated Maturity of the Notes, and
(iv) in the event such Indebtedness would be Incurred by a Restricted
Subsidiary, such Indebtedness would also qualify as Permitted Restricted
Subsidiary Indebtedness.
 
Notwithstanding the foregoing, the Company and its Restricted Subsidiaries may
Incur Permitted Indebtedness if no Default or Event of Default under any other
provision of the Indenture shall have occurred and be continuing at the time or
as a consequence of the Incurrence of such Indebtedness.
 
For purposes of calculating the amount of any Indebtedness of the Company and
its Restricted Subsidiaries, (i) any Indebtedness of a Restricted Subsidiary
that is fully and unconditionally guaranteed by the Company or secured by a
deposit of cash or Cash Equivalents of the Company shall be deemed to be
Indebtedness of such Restricted Subsidiary, and (ii) the Vinccler Notes shall be
deemed to be Indebtedness of the Company.
 
Limitation on Indebtedness of Unrestricted Subsidiaries.  The Company will not
permit any Unrestricted Subsidiary to Incur any Indebtedness (including Acquired
Indebtedness) other than Non-Recourse Indebtedness.
 
Limitation on Restricted Payments.  The Company will not, and will not permit
any of its Restricted Subsidiaries to, directly or indirectly, make any
Restricted Payment, if at the time of such Restricted Payment or after giving
effect to such Restricted Payment (i) the Company would not be able to Incur at
least $1.00 of additional Indebtedness (excluding Permitted Indebtedness)
pursuant to the provisions of the Indenture described above under "Limitation on
Indebtedness," and (ii) the aggregate amount expended for all Restricted
Payments (excluding any payments permitted by clauses (ii) through (ix) of the
immediately succeeding paragraph) (the amount of any such Restricted Payment, if
other than cash, as determined by the Board of Directors, whose determination
shall be evidenced by a board resolution) exceeds the sum of:
 
   
        (a) 50% of the aggregate Consolidated Net Income of the Company and its
     Restricted Subsidiaries (or, if such aggregate Consolidated Net Income
     shall be a loss, minus 100% of such loss) accrued for the period (taken as
     one accounting period) beginning on July 1, 1996 and ending on the last day
     of the Company's last fiscal quarter ending prior to the date of such
     proposed Restricted Payment, plus
    
 
        (b) 100% of the aggregate Net Proceeds received by the Company after
     June 30, 1996 from the issuance and sale (other than to a Subsidiary of the
     Company) of (1) Capital Stock (including options, warrants or other rights
     to acquire Capital Stock) other than any such Capital Stock convertible
     into or exchangeable for (whether at the option of the Company or the
     holder thereof) a security other than Capital Stock and other than any such
     Capital Stock issued for any purpose specified in clauses (vi) or (vii) of
     the succeeding paragraph and (2) Indebtedness convertible into or
     exchangeable for Capital Stock but only to the extent such Indebtedness has
     been converted or exchanged, plus
 
        (c) the aggregate amount of any Repaid Investments and Restricted
     Subsidiary Investments but only to the extent such amount did not otherwise
     increase the amount available for Restricted Payments pursuant to (a) above
     or clause (iv) of the immediately succeeding paragraph, plus
 
        (d) $15,000,000.
 
The foregoing provisions shall not be violated by reason of (i) the payment of
any dividend within 60 days after the date of declaration thereof, if at the
date of declaration such payment would comply with the foregoing provision, (ii)
any Investment in the Company by any Restricted Subsidiary and any Investment in
any Restricted Subsidiary or any person which concurrently with such Investment
becomes a Restricted Subsidiary by the Company or another Restricted Subsidiary,
(iii) any dividend payable to the Company by any Restricted Subsidiary or to any
Restricted Subsidiary by another Restricted Subsidiary, (iv) any dividend
payable to a holder (other than the Company or another Restricted Subsidiary) of
Capital Stock (other than Preferred Stock) of a Restricted Subsidiary; provided
that such dividend is paid concurrently with the payment of a dividend by such
Restricted Subsidiary to the Company or another Restricted Subsidiary and the
amount of such dividend does not exceed such holder's pro rata share (based on
such holder's percentage ownership of the outstanding Capital Stock (other than
Preferred Stock) of such Restricted Subsidiary) of the aggregate amount of the
dividend payable to all holders of Capital Stock of such Restricted Subsidiary,
(v) any dividend, distribution or other payment on or with respect to Capital
Stock of the Company
 
                                       54
<PAGE>   55
 
to the extent payable solely in shares of Capital Stock of the Company, (vi) any
purchase, redemption or other acquisition or retirement for value or any
defeasance of any Subordinated Indebtedness, in exchange for, by conversion into
or from the Net Proceeds of the substantially concurrent sale (other than to a
Subsidiary of the Company) of Capital Stock of the Company or new Subordinated
Indebtedness; provided the Average Life of such new Subordinated Indebtedness is
greater than the Average Life of the Notes, the stated maturity of such new
Subordinated Indebtedness is later than the Stated Maturity of the Notes and the
new Subordinated Indebtedness is subordinated to the Notes to at least the
extent that the Subordinated Indebtedness being purchased, redeemed, acquired,
retired or defeased was subordinated to the Notes, (vii) any purchase,
redemption or other acquisition or retirement for value of any shares of Capital
Stock of the Company in exchange for, by conversion into or from the Net
Proceeds of the substantially concurrent sale (other than to a Subsidiary of the
Company) of Capital Stock of the Company, (viii) any Investment in a person that
represents the portion of the consideration for an Asset Sale that is not, and
is not required to be pursuant to the provisions of the Indenture described
below under "Disposition of Proceeds of Asset Sales," cash or Cash Equivalents
and (ix) payments or distributions pursuant to or in connection with a
consolidation, merger or transfer of assets that complies with the provisions of
the Indenture described below under "Consolidation, Merger, Conveyance, Transfer
or Lease"; provided that, in the case of any of the foregoing, no Default or
Event of Default has occurred and is continuing or shall occur as a consequence
thereof.
 
Limitation on Transactions with Affiliates.  The Company will not, and will not
permit any Subsidiary to, directly or indirectly, enter into any transaction or
series of related transactions (including, without limitation, the sale,
purchase, exchange or lease of assets, property or services) (such a transaction
or series of related transactions, an "Affiliate Transaction") with (i) any
Affiliate of the Company or any Subsidiary or (ii) any officer, director or
employee of the Company or any Subsidiary or any Affiliate thereof unless (i)
such Affiliate Transaction is on terms that are no less favorable to the Company
or such Subsidiary, as the case may be, than those that would have been
available in a comparable arm's-length transaction with an unaffiliated third
party, and (ii) (a) with respect to any Affiliate Transaction involving
aggregate payments equal to or in excess of $1 million (or, in the case of any
loan or advance to any officer, director or employee of the Company or its
Restricted Subsidiaries, $100,000), but less than $5 million, such Affiliate
Transaction shall have received the approval of a majority of the Disinterested
Directors (as evidenced by a board resolution of such Disinterested Directors)
and (b) with respect to any Affiliate Transaction involving aggregate payments
equal to or greater than $5 million, the Company shall have obtained a written
opinion of an Independent Financial Advisor stating that the terms of such

be, from a financial point of view.
 
The foregoing limitations shall not apply to (i) any transaction between the
Company and any Restricted Subsidiary or between Restricted Subsidiaries, (ii)
the payment of reasonable and customary regular fees to directors of the Company
who are not employees of the Company, (iii) any employment contract to which any
officer, director or employee is a party or stock option plan or grant of any

involving aggregate payments (or in the case of any option grant, with an
aggregate exercise price) equal to or in excess of $100,000 shall have received
the approval of the Compensation Committee of the Board of Directors (as
evidenced by a resolution of such Committee) which Committee shall be comprised
of Disinterested Directors, or (iv) any Permitted Investment or any Restricted
Payments not prohibited by the provisions of the Indenture described above under
"Limitation on Restricted Payments."
 
Disposition of Proceeds of Asset Sales.  The Company will not, and will not
permit any Restricted Subsidiary to, make any Asset Sale unless (i) such Asset
Sale is for not less than the fair market value of the properties and assets
sold, (ii) at least 85% of the consideration (not including the assumption of
any Indebtedness of the Company or any Restricted Subsidiary (other than
Subordinated Indebtedness)) consists of cash, Cash Equivalents or Publicly
Traded Stock (so long as prior to such Asset Sale the Board of Directors has
made a determination as evidenced by a board resolution, to sell such Publicly
Traded Stock for cash within ten Business Days after the date of such Asset Sale
and such Publicly Traded Stock does not constitute more than 30% of such 85%),
except (a) in the case of an Asset Sale involving oil and gas properties, the
consideration may consist solely or in part of tangible properties or direct or
indirect interests in tangible properties to be used in the Company's or its
Restricted Subsidiaries' Oil and Gas Business ("Tangible Business Properties")
having a fair market value at least equal to the fair market value of the assets
exchanged and (b) the Company and its Restricted Subsidiaries may enter into
farm-out transactions consistent with industry standards and otherwise in
accordance with the terms of the Indenture including, but not limited to, the
provisions described above under "Limitation on Transactions with Affiliates"

has made a determination, as evidenced by a board resolution, to use all of the
Net Cash Proceeds of such Asset Sale that consist of cash and Cash Equivalents
to permanently repay or prepay Senior Indebtedness or Indebtedness of a
Restricted Subsidiary within thirty days after the date of such Asset Sale, the
Company could Incur an additional $1.00 of Indebtedness (other than Permitted
Indebtedness) pursuant to the provisions of the Indenture described above under
"Limitation on Indebtedness," (iv) within ten Business Days after the date of
such Asset Sale, any Publicly Traded Stock
 
                                       55
<PAGE>   56
 
required by a board resolution to be sold for cash, is sold for cash, and (v)
the requirements set forth below are met. For purposes of the foregoing, in the
case of any required fair market value determination with respect to any Asset
Sale or Tangible Business Properties or Publicly Traded Stock acquired in
connection with such Asset Sale having a fair market value in excess of $5
million, such determination shall be made by the Board of Directors as evidenced
by a board resolution.
 
Subject to clause (iii) above, within twelve months of any Asset Sale, the
Company shall either (x) apply or cause the application of an amount equal to
the Net Cash Proceeds of such Asset Sale, or a portion thereof, to the permanent
repayment or prepayment of Senior Indebtedness or Indebtedness of any Restricted
Subsidiary or (y) invest such Net Cash Proceeds, or a portion thereof, in the
acquisition or development of Tangible Business Properties. The amount of such
Net Cash Proceeds not applied, used or invested as set forth in clause (x) or
(y) above shall constitute "Excess Proceeds."
 
If the aggregate amount of Excess Proceeds, together with any remaining Excess
Proceeds from any prior Asset Sale, equals or exceeds $25 million, the Company
shall so notify the Trustee in writing and shall offer to purchase from all
holders of the Notes (an "Asset Sale Offer"), and shall purchase from holders
accepting such Asset Sale Offer on the date fixed for such Asset Sale Offer (the
"Asset Sale Offer Date"), the maximum amount (expressed in integral multiples of
aggregate principal amount of $1,000) of Notes that may be purchased out of the
Excess Proceeds, in accordance with the procedures set forth in the Indenture,
at an offer price in cash in an amount equal to 100% of the principal amount
thereof plus accrued and unpaid interest, if any, to the Asset Sale Offer Date.
To the extent that the aggregate amount of Notes tendered pursuant to an Asset
Sale Offer is less than the Excess Proceeds relating thereto (such shortfall
constituting a "Deficiency"), then the Company may use such Deficiency, or a
portion thereof, for general corporate purposes. Upon completion of an Asset
Sale Offer, the amount of Excess Proceeds shall be reset at zero.
 
Limitation on Liens Securing Indebtedness.  The Company will not, and will not
permit any Restricted Subsidiary to, create, incur, assume or suffer to exist
any Lien of any kind upon any of their respective assets or properties now owned
or acquired after the date of the Indenture, or any income or profits therefrom,
securing any Indebtedness of the Company or any Restricted Subsidiary (other
than Permitted Liens) without making provision for all of the Notes to be
equally and ratably secured with (or prior to) such Indebtedness, provided,
however that if such Lien securing such Indebtedness ceases to exist, such equal
and ratable (or prior) Lien for the benefit of the holders of the Notes shall
cease to exist; provided, further, that the Lien securing any Subordinated
Indebtedness shall be subordinated to the Lien securing the Notes to at least
the extent that such Subordinated Indebtedness is subordinated to the Notes.
 
Limitation on Conduct of Business.  The Company will operate and will cause its
Restricted Subsidiaries to be operated in a manner such that their business
activities will be the Oil and Gas Business.
 
Limitation on Dividends and Other Payment Restrictions Affecting Restricted
Subsidiaries.  The Company will not, and will not permit any Restricted
Subsidiary to, create or otherwise cause or suffer to exist or become effective
any consensual encumbrance or restriction on the ability of any Restricted
Subsidiary to (i) pay dividends or make any other distributions on Capital Stock
of any Restricted Subsidiary or any Redeemable Stock of any Restricted
Subsidiary owned by the Company or any Restricted Subsidiary, (ii) pay any
Indebtedness owed to the Company or any Restricted Subsidiary, (iii) make any
Investment in the Company or any Restricted Subsidiary or (iv) transfer any of
its property or assets to the Company or any Restricted Subsidiary, except (a)
any encumbrance or restriction pursuant to an agreement in effect on the date of
the Indenture, (b) any encumbrance or restriction with respect to any person
that is not a Restricted Subsidiary on the date of the Indenture, in existence
at the time such person becomes a Restricted Subsidiary and not created in
connection with, or in contemplation of, such person becoming a Restricted
Subsidiary so long as such encumbrance or restriction is not applicable to any
person or the property or assets of any person other than the person becoming a
Restricted Subsidiary, (c) any encumbrance or restriction pursuant to any
agreement that extends, refinances, renews or replaces any agreement containing
any encumbrance or restriction described in the foregoing clauses (a) and (b),
provided, however, that the terms and conditions of any such encumbrance or
restriction are not less favorable to the holders of the Notes than those
contained in the agreement evidencing the restriction or encumbrance so
extended, refinanced, renewed or replaced, (d) any encumbrance or restriction
arising under law and (e) any restriction arising under customary non-assignment
and nonsubletting clauses in leases. Nothing contained in the provisions of the
Indenture described in this paragraph shall prevent the Company or any
Restricted Subsidiary from entering into any agreement permitting the incurrence
of Liens otherwise permitted under the provisions of the Indenture described
above under the "Limitation on Liens Securing Indebtedness."
 
Limitation on Guarantees.  The Company will not permit any Restricted
Subsidiary, directly or indirectly, to assume, guarantee or in any other manner
become liable with respect to the payment of any Indebtedness of the Company
unless such Restricted Subsidiary simultaneously executes and delivers a
supplemental indenture to the Indenture providing for a guarantee of the payment
of the Notes by such Restricted Subsidiary; provided, however, in the case of
such Restricted Subsidiary's assumption, guarantee, or other liability with
respect to Subordinated Indebtedness, such guarantee, assumption or other
liability shall be
 
                                       56
<PAGE>   57
 
subordinated to such Restricted Subsidiary's guarantee of the Notes to at least
the extent that such Subordinated Indebtedness is subordinated to the Notes; and
provided, further, that the provisions of the Indenture described in this
paragraph shall not be applicable to any guarantee, assumption or other
liability with respect to the payment of any Indebtedness of the Company by any
Restricted Subsidiary (i) in existence on the date of the Indenture, (ii) to the
extent such Indebtedness of the Company could be Incurred by such Restricted
Subsidiary as Permitted Restricted Subsidiary Indebtedness, or (iii) that (x)
existed at the time such person became a Restricted Subsidiary of the Company
and (y) was not Incurred in connection with, or in contemplation of, such person
becoming a Restricted Subsidiary. Notwithstanding the foregoing, any such
guarantee of the Notes by a Restricted Subsidiary shall provide by its terms
that it shall be automatically and unconditionally released and discharged upon
the release or discharge of such guarantee of such Indebtedness, other than a
release or discharge by, or as a result of, any payment under such guarantee by
such Restricted Subsidiary.
 
CHANGE IN CONTROL
 
If there shall have occurred a Change in Control, Notes shall be purchased by
the Company, at the option of the holder thereof, in whole or in part in
integral multiples of aggregate principal amount of $1,000, on a date that is
not earlier than 45 days nor later than 60 days from the date the Change in
Control Notice is given to holders or such later date as may be necessary for
the Company to comply with requirements under the Exchange Act (such date or
such later date, being the "Change in Control Purchase Date"), at a purchase
price in cash (the "Change in Control Purchase Price") equal to 101% of the
principal amount thereof plus accrued and unpaid interest, if any, to any Change
in Control Purchase Date subject to satisfaction by or on behalf of the holder
of the requirements established pursuant to the Indenture. The Company shall
comply with any applicable tender offer rules then in effect, including Section
14(e) of the Exchange Act and Rule 14e-1 promulgated thereunder (or any
successor provisions), in connection with a Change in Control offer. In the
event of any conflict between such tender offer rules and the provisions set
forth in the Indenture, such tender offer rules shall control.
 
"Change in Control" of the Company means the occurrence of any of the following:
(i) any "person" (as such term is used in Sections 13(d) and 14(d) (or any
successor provisions) of the Exchange Act) is or becomes the "beneficial owner"
(as defined in Rules 13d-3 and 13d-5 (or any successor provisions) under the
Exchange Act) of 50% or more of the total voting power of the Voting Stock of
the Company, (ii) there shall be consummated any consolidation or merger of the
Company (a) in which the Company is not the continuing or surviving corporation
or (b) pursuant to which the outstanding Voting Stock of the Company would be
converted into cash, securities or other property, in each case other than a
consolidation or merger of the Company in which (1) the outstanding Voting Stock
of the Company is changed into or exchanged for Voting Stock of the continuing
or surviving corporation and (2) the holders of the Company's Voting Stock
immediately prior to the consolidation or merger own, directly or indirectly, at
least a majority of the Voting Stock of the continuing or surviving corporation
immediately after the consolidation or merger, (iii) the Company sells,
transfers or otherwise disposes of all or substantially all of its assets, (iv)
the cessation of Continuing Directors for any reason to constitute a majority of
the Board of Directors then in office, (v) so long as any Indebtedness remains
outstanding under the Convertible Debenture Indenture, a Fundamental Change as
defined therein, (vi) the Company ceases to own on a fully diluted basis,
directly or indirectly through one or more Restricted Subsidiaries that are
Wholly Owned Subsidiaries of the Company, 51% of the outstanding Voting Stock of
Benton-Vinccler, and (vii) Benton-Vinccler sells, transfers or otherwise
disposes of a substantial part of its assets; provided that neither of the
events described in clause (vi) or (vii) will constitute a "Change in Control"
if (x) during the four full fiscal quarters ended immediately prior to the
occurrence of such event, the EBITDA of the Company and its Restricted
Subsidiaries attributable to Benton-Vinccler, as a percentage of the EBITDA of
the Company and its Restricted Subsidiaries, was less than 20% and (y)
immediately prior to such event, the Oil and Gas Reserve Estimate of the Company
and its Restricted Subsidiaries attributable to Benton-Vinccler as a percentage
of the Oil and Gas Reserve Estimate of the Company and its Restricted
Subsidiaries, is less than 20%.
 
In connection with clause (vii) of the preceding paragraph, a sale, transfer or
other disposition of assets of Benton-Vinccler shall be deemed to be a sale,
transfer or other disposition of a "substantial part" of the assets of
Benton-Vinccler if such assets, when added to all other assets of
Benton-Vinccler sold, transferred or otherwise disposed of (other than the
disposition of hydrocarbons or other mineral products in the ordinary course of
business) during the immediately preceding twelve months either (i) exceed
(based on the book value of all assets so sold, transferred or otherwise
disposed of during such twelve months) 25% of the net tangible assets of
Benton-Vinccler as of the end of its most recently completed full fiscal quarter
for which financial information is available determined in accordance with GAAP
or (ii) contributed more than 25% of the net income of Benton-Vinccler during
its most recently completed four full fiscal quarters for which financial
information is available determined in accordance with GAAP.
 
The Company's ability to repurchase the Notes will be dependent upon the
availability of cash and other financing sources to consummate such a
repurchase. The Company currently expects to incur additional Indebtedness to
finance its capital
 
                                       57
<PAGE>   58
 
expenditure requirements and, therefore, the Company's ability to incur
additional Indebtedness to repurchase the Notes may be adversely affected by
what might then be a higher debt to equity ratio. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations -- Capital
Resources and Liquidity." The failure of the Company to repurchase all Notes
tendered will constitute an Event of Default.
 
The Change in Control provisions of the Indenture may make more difficult or
discourage a takeover of the Company and the removal of incumbent management.
The Change in Control provision is not the result of management's knowledge of
any specific effort to accumulate shares of Common Stock or to obtain control of
the Company by means of a merger, tender offer, solicitation or otherwise, nor
is it part of a plan by management to adopt an anti-takeover provision.
 
CONSOLIDATION, MERGER, CONVEYANCE, TRANSFER OR LEASE
 
The Company may not, without the consent of the holders of all Notes then
outstanding, consolidate with, merge into or convey, sell, transfer, lease,
exchange or otherwise dispose of all of its assets and properties substantially
as an entirety to, any other person unless (i) the successor is a corporation or
partnership organized under the laws of the United States or any political
subdivision thereof or therein, (ii) the successor assumes all obligations of
the Company under the Indenture and the Notes, (iii) after giving effect to such
consolidation, merger, conveyance, sale, transfer, lease, exchange or other
disposition, no Default or Event of Default, shall have occurred and be
continuing, (iv) the successor would have a pro forma Consolidated Net Worth
after giving effect to such consolidation, merger, conveyance, sale, transfer,
lease, exchange or other disposition and prior to any purchase accounting
adjustments at least equal to the Consolidated Net Worth of the Company prior to
such consolidation, merger, conveyance, sale, transfer, lease, exchange or other
disposition, and (v) the Company could Incur, immediately prior to such
consolidation, merger, conveyance, sale, transfer, lease, exchange or other
disposition, and the successor would be able to Incur, after giving effect to
such consolidation, merger, conveyance, sale, transfer, lease, exchange or other
disposition, an additional $1.00 of Indebtedness (excluding Permitted
Indebtedness) pursuant to the provisions of the Indenture described above under
"Certain Covenants -- Limitation on Indebtedness."
 
Upon any consolidation or merger or any conveyance, sale, transfer, lease,
exchange or other disposition of the properties and assets of the Company
substantially as an entirety to any person in accordance with the provisions
described above, the successor formed by such consolidation or into which the
Company is merged or to which such conveyance, sale, transfer, lease, exchange
or other disposition is made shall succeed to, and be substituted for, and may
exercise every right and power of, the Company under the Indenture with the same
effect as if such successor had been named as the Company in the Indenture; and
thereafter, except in the case of a conveyance, sale, transfer, lease, exchange
or other disposition of properties to another person, the predecessor person
shall be released from all obligations and covenants under the Indenture and the
Notes.
 
PROVISION OF FINANCIAL INFORMATION
 
   
To the extent permitted under the Exchange Act, whether or not the Company is
required to comply with Section 13(a) or 15(d) (or any successor provision) of
the Exchange Act, the Company will file with the Commission the annual reports,
quarterly reports and other documents which the Company would have been required
to file with the Commission pursuant to such Section 13(a) or 15(d) (or any
successor provision) if the Company were so required, such documents to be filed
with the Commission on or prior to the respective dates (the "Required Filing
Dates") by which the Company would have been required to file such documents if
the Company were so required. The Company will also in any event (i) within 15
days of each Required Filing Date transmit by mail to all holders of New Notes,
without cost to such holders, copies of the annual reports, quarterly reports
and other documents which the Company would have been required to file with the

permitted under the Exchange Act, promptly upon written request supply copies of

     or any Restricted Subsidiary which require the payment in money, either
     individually or in an aggregate amount, of more than $500,000 shall remain
     unsatisfied or unstayed for 30 consecutive days after any such judgment or
     order becomes final and nonappealable; or
 
        (f) the entry of a decree or order by a court having jurisdiction in the
     premises (i) for relief in respect of the Company or any Material
     Subsidiary in an involuntary case or proceeding under any applicable
     bankruptcy, insolvency or other similar law now or hereafter in effect, or
     (ii) adjudging the Company or any such Material Subsidiary as bankrupt or
     insolvent, or seeking reorganization, arrangement, adjustment or
     composition of or in respect of the Company or any such Material Subsidiary
     under any such law, or (iii) appointing a custodian, receiver, liquidator,
     assignee, trustee, sequestrator (or other similar official) of the Company
     or any such Material Subsidiary or of any substantial part of any of their
     properties, or ordering the winding up or liquidation of any of their
     affairs, and the continuance of any such decree or order unstayed and in
     effect for a period of 60 consecutive days; or
 
                                       67
<PAGE>   68
 
        (g) the institution by the Company or any Material Subsidiary of a
     voluntary case or proceeding under any applicable bankruptcy, insolvency or
     other similar law now or hereafter in effect, or the consent by the Company
     or any Material Subsidiary to the entry of a decree or order for relief in
     respect of the Company or any Material Subsidiary in any involuntary case
     or proceeding under any such law or to the institution of bankruptcy or
     insolvency proceedings against the Company or such Material Subsidiary, or
     the filing by the Company or any Material Subsidiary of a petition or
     answer or consent seeking reorganization or relief under any such law, or
     the consent by the Company or any Material Subsidiary to the filing of any
     such petition or to the appointment of or taking possession by a custodian,
     receiver, liquidator, assignee, trustee, sequestrator (or other similar
     official) of any of the Company or such Material Subsidiary or any
     substantial part of any of their properties, or the making by the Company
     or any Material Subsidiary of an assignment for the benefit of creditors,
     or the admission by the Company or any Material Subsidiary in writing of an
     inability to pay any of their debts generally as they become due or the
     taking of corporate action by the Company or any Material Subsidiary in
     furtherance of any such action.
 
If an Event of Default with respect to the Notes (other than as specified in
clauses (f) and (g) above) occurs and is continuing, either the Trustee or the
holders of at least 25% in aggregate principal amount of the Notes then
outstanding, by written notice to the Company (and to the Trustee if such notice
is given by holders) may, and the Trustee at the request of such holders shall,
declare the Notes and the accrued interest thereon to be immediately due and
payable, as specified below. Upon a declaration of acceleration, such amount
shall be due and payable immediately after receipt by the Company of such
written notice. If an Event of Default specified in clause (f) or (g) above
occurs and is continuing, then the Notes and the accrued interest thereon shall
become and be immediately due and payable without any declaration or other act
on the part of the Trustee or any holder. At any time after such declaration of
acceleration has been made and before a judgment or decree for payment of the
money due has been obtained by the Trustee, the holders of a majority in
aggregate principal amount of the Notes outstanding, by written notice to the
Company and the Trustee, may rescind and annul such declaration and its
consequences if: (a) the Company has paid or deposited with the Trustee a sum
sufficient to pay (i) all sums paid or advanced by the Trustee and the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel and (ii) the amounts payable in respect of any Notes
which have become due otherwise than by such declaration of acceleration and
overdue interest thereon (to the extent of such overdue interest at the rate
borne by the Notes) and (b) the rescission would not conflict with any judgment
or decree and (c) all existing Events of Default, other than the nonpayment of
the principal amount of the Notes which have become due solely by such
declaration of acceleration, have been cured or waived. No such rescission shall
affect any subsequent Default or impair any right consequent thereon provided in
the following paragraph.
 
The holders of not less than a majority in aggregate principal amount of the
outstanding Notes, by notice to the Trustee (and without notice to any other
holder) on behalf of the holders of all the Notes may waive any past default or
Event of Default under the Indenture with respect to such Notes and its
consequences, except (i) an Event of Default described in clause (b) of the
first paragraph under this section or (ii) a default in the payment of interest
on any Notes or in respect of a covenant or provision that under the terms of
the Indenture cannot be modified or amended without the consent of the holder of
each outstanding Note affected thereby. Upon any such waiver, such default shall
cease to exist, and any Event of Default arising therefrom shall be deemed to
have been cured, for every purpose of the Indenture; but no such waiver shall
extend to any subsequent or other default or impair any right consequent
thereto.
 
In the Indenture, (i) the Company will covenant that (to the extent that it may
lawfully do so) it will not at any time insist upon, or plead, or in any manner
whatsoever claim or take the benefit or advantage of, any stay or extension law
wherever enacted, now or at any time hereafter in force, which may affect the
covenants or the performance of the Indenture and the Company will expressly
waive (to the extent that it may lawfully do so) all benefit or advantage of any
such law and (ii) the Company will covenant that it will not hinder, delay or
impede the execution of any power granted to the Trustee under the Indenture and
will suffer and permit the execution of every such power as though no such law
had been enacted.
 
DEFEASANCE; SATISFACTION AND DISCHARGE
 
The Indenture will provide that (i) the Company may be discharged from any and
all obligations in respect of the outstanding Notes or (ii) the Company may omit
to comply with certain restrictive covenants and that such omission shall not be
deemed to be an Event of Default under the Indenture and the Notes in the case
of either clause (i) or (ii) upon irrevocable deposit with the Trustee, in
trust, of money and/or U.S. government obligations which will provide money in
an amount sufficient in the opinion of a nationally recognized firm of
independent certified accountants to pay the principal of and each installment
of interest, if any, on the outstanding Notes. With respect to clause (ii), the
obligations under the Indenture other than with respect to such covenants and
the Events of Default other than the Event of Default relating to such covenants
shall remain in full force and effect. Such trust may only be established if,
among other things (a) with respect to clause (i), the Company has delivered to
the Trustee an Opinion of Counsel stating that the Company has received from, or
there has been published by, the Internal
 
                                       68
<PAGE>   69
 
Revenue Service a ruling or there has been a change in law, and based thereon
such Opinion of Counsel confirms that holders of the Notes will not recognize
gain or loss for federal income tax purposes as a result of such deposit,
defeasance and discharge and will be subject to federal income tax on the same
amount, in the same manner and at the same times as would have been the case if
such deposit, defeasance and discharge had not occurred or, with respect to
clause (ii), the Company has delivered to the Trustee an Opinion of Counsel to
the effect that the holders of the Notes will not recognize gain or loss for
federal income tax purposes as a result of such deposit and defeasance and will
be subject to federal income tax on the same amount, in the same manner and at
the same times as would have been the case if such deposit and defeasance had
not occurred; (b) no Event of Default or Default shall have occurred or be
continuing; (c) the Company has delivered to the Trustee an Opinion of Counsel
to the effect that such deposit shall not cause the Trustee or the trust so
created to be subject to the Investment Company Act of 1940, as amended; and (d)
certain other customary conditions precedent are satisfied.
 
The Indenture will cease to be of further effect (except as to surviving rights
of registration of transfer or exchange of Notes, substitution of apparently
mutilated, defaced, destroyed, lost or stolen Notes, rights of holders to
receive payments of principal and interest and rights of holders of Notes to
funds deposited with the Trustee) as to all outstanding Notes when either (i)
all such Notes theretofore authenticated and delivered (except lost, stolen or
destroyed Notes which have been replaced or paid) have been delivered to the
Trustee for cancellation, (ii) the Company has paid the principal of and
interest on all Notes outstanding under the Indenture as and when the same shall
have become due and payable, or (iii) all such Notes not theretofore delivered
to the Trustee for cancellation (a) have become due and payable, or (b) will
become due and payable within one year, or (c) are to be called for redemption
within one year, and (x) the Company has irrevocably deposited or caused to be
deposited with the Trustee funds in an amount sufficient to pay the entire
indebtedness on such Notes not theretofore delivered to the Trustee for
cancellation, for principal (and premium, if any) and interest to the date of
deposit (if such Notes are then due and payable) or to the applicable maturity
or redemption date (as the case may be), (y) no default or Event of Default
shall have occurred or be continuing and (z) such deposit would not result in a
breach or violation of, or constitute a default under, the Indenture or any
other agreement or instrument to which the Company is a party or by which it is
bound, and the Company has paid all sums payable by it under the Indenture.
 
GOVERNING LAW
 
The Indenture and the Notes will be governed by the laws of the State of New
York.
 
MODIFICATION OF INDENTURE
 
The Indenture contains provisions permitting the Company and the Trustee in
limited circumstances, and otherwise, with the consent of the holders of not
less than a majority in aggregate principal amount of Notes at the time
outstanding, to execute supplemental indentures adding any provisions to or
changing in any manner or eliminating any of the provisions of the Indenture or
any supplemental indenture or modifying in any manner the rights of the holders
of the Notes; provided that no such supplemental indenture shall (i) extend the
final maturity of any Note, or reduce the principal amount thereof, or reduce
the rate or extend the time of payment of interest thereon, or reduce any amount
payable on redemption of any Notes or upon an Event of Default, or reduce the
Change in Control Purchase Price of the Asset Sale Offer Price, or impair or
affect the right of any holder to institute suit for the payment thereof without
the consent of the holder of each Note so affected, or (ii) reduce the aforesaid
percentage of Notes, the consent of the holders of which is required for any
supplemental indenture, without the consent of the Holders of all Notes then
outstanding.
 
THE TRUSTEE
 
The Indenture provides that, except during the continuance of an Event of
Default, the Trustee will perform only such duties as are specifically set forth
in the Indenture. During the existence of an Event of Default, the Trustee will
exercise such rights and powers vested in it under the Indenture and use the
same degree of care and skill in its exercise as a prudent person would exercise
under the circumstances in the conduct of such person's own affairs.
 
   
THE GLOBAL NOTES
    
 
Upon the issuance of the Regulation S Global Note and the Restricted Global Note
(each a "Global Note" and together the "Global Notes"), DTC or its custodian
will credit, on its internal system, the respective principal amount of the
individual beneficial interests represented by such Global Note to the accounts
of persons who have accounts with such depositary. Such accounts initially will
be designated by or on behalf of the Initial Purchaser. Ownership of beneficial
interests in a Global Note will be limited to persons who have accounts with DTC
("participants") or persons who hold interests through participants. Ownership
of beneficial interests in a Global Note will be shown on, and the transfer of
that ownership will be effected only
 
                                       69
<PAGE>   70
 
through, records maintained by DTC or its nominee (with respect to interests of
participants) and the records of participants (with respect to interests of
persons other than participants). Qualified institutional buyers may hold their
interests in a Global Note directly through DTC if they are participants in such
system, or indirectly through organizations which are participants in such
system.
 
Investors may hold their interests in the Regulation S Global Note directly
through Cedel or Euroclear, if they are participants in such systems, or
indirectly through organizations that are participants in such system. Beginning
40 days after the later of the commencement of the offering and the Closing Date
(but not earlier), investors may also hold such interests through organizations
other than Cedel or Euroclear that are participants in the DTC system. Cedel and
Euroclear will hold interests in the Regulation S Global Note on behalf of their
participants through DTC.
 
So long as DTC, or its nominee, is the registered owner of holder of a Global
Note, DTC or such nominee, as the case may be, will be considered the sole owner
or holder of the Notes represented by such Global Note for all purposes under
the Indenture and the Notes. No beneficial owner of an interest in a Global Note
will be able to transfer that interest except in accordance with the procedures
provided for under "Notice to Investors," as well as DTC's applicable
procedures, and, if applicable, those of Euroclear and Cedel.
 
Payments of the principal of, and interest on, the Global Notes will be made to
DTC or its nominee, as the case may be, as the registered owner thereof. None of
the Company, the Trustee or any Paying Agent will have any responsibility or
liability for any aspect of the records relating to or payments made on account
of beneficial ownership interests in the Global Notes or for maintaining,
supervising or reviewing any records relating to such beneficial ownership
interests.
 
The Company expects that DTC or its nominee, upon receipt of any payment of
principal or interest in respect of a Global Note will credit participants'
accounts with payments in amounts proportionate to their respective beneficial
interests in the principal amount of such Global Note as shown on the records of
DTC or its nominee. The Company also expects that payments by participants to
owners of beneficial interests in such Global Note held through such
participants will be governed by standing instructions and customary practices,
as is now the case with securities held for the accounts of customers registered
in the name of nominees for such customers. Such payments will be the
responsibility of such participants.
 
Transfers between participants in DTC will be effected in the ordinary way in
accordance with DTC rules and will be settled in same-day funds. If a holder
requires physical delivery of a Certificated Note for any reason, including to
sell Notes to persons in states which require such delivery of such Notes or to
pledge such Notes, such holder must transfer its interest in the Global Note in
accordance with the normal procedures of DTC and the procedures set forth in
"Transfer Restrictions." Transfers between participants in Euroclear and Cedel
will be effected in the ordinary way in accordance with their respective rules
and operating procedures.
 
DTC has advised the Company that it will take any action permitted to be taken
by a holder of Notes (including the presentation of Notes for exchange as
described below) only at the direction of one or more participants to whose
accounts the DTC interests in the Global Notes is credited and only in respect
of such portion of the aggregate principal amount of Notes as to which such
participant or participants has or have given such direction. However, if there
is an Event of Default (as defined below) under the Notes, DTC will exchange the
Global Notes for Certificated Notes, which it will distribute to its
participants and which, if representing interests in the Restricted Global Note
or the Temporary Regulation S Global Note, will be legended as set forth under
the heading "Notice to Investors."
 
DTC has advised the Company as follows: DTC is a limited purpose trust company
organized under the laws of the State of New York, a "banking organization"
within the meaning of New York Banking Law, a member of the Federal Reserve
System, a "clearing corporation" within the meaning of the Uniform Commercial
Code and a "Clearing Agency" registered pursuant to the provisions of Section
17A of the Exchange Act. DTC was created to hold securities for its participants
and facilitate the clearance and settlement of securities transactions between
participants through electronic book-entry changes in accounts of its
participants, thereby eliminating the need for physical movement of
certificates. Participants include securities brokers and dealers, banks, trust
companies and clearing corporations and certain other organizations. Indirect
access to the DTC system is available to others such as banks, brokers, dealers
and trust companies that clear through or maintain a custodial relationship with
a participant, either directly or indirectly ("indirect participants").
 
Although DTC, Euroclear and Cedel have agreed to the foregoing procedures in
order to facilitate transfers of interests in the Global Notes among
participants of DTC, Euroclear and Cedel, they are under no obligation to
perform or continue to perform such procedures, and such procedures may be
discontinued at any time. Neither the Company nor the Trustee will have any
responsibility for the performance by DTC, Euroclear or Cedel or their
respective participants or indirect participants of their respective obligations
under the rules and procedures governing their operations.
 
                                       70
<PAGE>   71
 
CERTIFICATED NOTES
 
If DTC is at any time unwilling or unable to continue as a depositary for the
Global Notes and a successor depositary is not appointed by the Company within
90 days, the Company will issue Certificated Notes in exchange for the Global
Notes which, in the case of Notes issued in exchange for the Restricted Global
Note will bear the legend referred to under the heading "Notice to Investors."
 
   
                          DESCRIPTION OF THE OLD NOTES
    
 
   
The terms of the Old Notes are identical in all material respects to the New
Notes, except that (i) the sale of the Old Notes was not registered under the
Securities Act, therefore the Old Notes are subject to certain restrictions on
transfer, contain certain legends relating thereto and are entitled to certain
registration rights under the Registration Rights Agreement (which rights will
terminate upon consummation of the Exchange Offer); and (ii) the New Notes will
not provide for any increase in the interest rate thereon. In that regard, the
Old Notes provide that, in the event that the Exchange Offer is not consummated
or a shelf registration statement (the "Shelf Registration Statement") with
respect to the resale of the Old Notes is not declared effective on or prior to
August 31, 1996, or if the Exchange Offer is not consummated on or prior to
August 31, 1996, the interest rate on the Old Notes will increase by 0.50% per
annum until the Exchange Offer is consummated. Upon the consummation of the
Exchange Offer or the effectiveness of a Shelf Registration Statement, as the
case may be, after August 31, 1996, the interest rate on any Old Notes which
remain outstanding will be reduced, from the date of such consummation or
effectiveness, as the case may be, to 11 5/8% per annum and the Old Notes will
not thereafter be entitled to any increase in the interest rate thereon. The New
Notes are not entitled to any such increase in the interest rate thereon. In
addition, the Old Notes and the New Notes will constitute a single series of
debt securities under the Indenture. See "Description of the New
Notes -- General." Accordingly, holders of Old Notes should review the
information set forth under "Summary -- Certain Consequences of a Failure to
Exchange Old Notes" and "Description of the New Notes."
    
 
   
            CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS
    
 
The following summary describes certain United States Federal income tax
considerations to holders of the New Notes who are subject to U.S. net income
tax with respect to the New Notes ("U.S. persons") and who will hold the New
Notes as capital assets. There can be no assurance that the U.S. Internal
Revenue Service (the "IRS") will take a similar view of the purchase, ownership
or disposition of the New Notes. This discussion is based upon the provisions of
the Internal Revenue Code of 1986, as amended, and regulations, rulings and
judicial decisions now in effect, all of which are subject to change. It does
not include any description of the tax laws of any state, local or foreign
governments or any estate or gift tax considerations that may be applicable to
the New Notes or holders thereof. It does not discuss all aspects of U.S.
Federal income taxation that may be relevant to a particular investor in light
of his particular investment circumstances or to certain types of investors
subject to special treatment under the U.S. Federal income tax laws (for
example, dealers in securities or currencies, S corporations, life insurance
companies, tax-exempt organizations, taxpayers subject to the alternative
minimum tax and non-U.S. persons) and also does not discuss New Notes held as a
hedge against currency risks or as part of a straddle with other investments or
as part of a "synthetic security" or other integrated investment (including a
"conversion transaction") comprised of a New Note and one or more other
investments, or situations in which the functional currency of the holders is
not the U.S. dollar.
 
Holders of Old Notes contemplating acceptance of the Exchange Offer should
consult their own tax advisors with respect to their particular circumstances
and with respect to the effects of state, local or foreign tax laws to which
they may be subject.
 
   
EXCHANGE OF NOTES
    
 
The exchange of Old Notes for New Notes should not be a taxable event to holders
for federal income tax purposes. The exchange of Old Notes for the New Notes
pursuant to the Exchange Offer should not be treated as an "exchange" for
federal income tax purposes because the New Notes should not be considered to
differ materially in kind or extent from the Old Notes. If, however, the
exchange of the Old Notes for the New Notes were treated as an exchange for
federal income tax purposes, such exchange should constitute a recapitalization
for federal income tax purposes. Accordingly, a holder should have the same
adjusted basis and holding period in the New Notes as it had in the Old Notes
immediately before the exchange.
 
   
INTEREST ON THE NEW NOTES
    
 
A holder of a New Note will be required to report as ordinary interest income
for U.S. Federal income tax purposes interest earned on the New Note in
accordance with the holder's method of tax accounting.
 
                                       71
<PAGE>   72
 
   
DISPOSITION OF NEW NOTES
    
 
   
A holder's tax basis for a New Note generally will be the holder's purchase
price for the Old Note. Upon the sale, exchange, redemption, retirement or other
disposition of a New Note, a holder will recognize gain or loss equal to the
difference (if any) between the amount realized and the holder's tax basis in
the New Note. Such gain or loss will be long-term capital gain or loss if the
New Note has been held for more than one year (including the period the Old Note
was held) and otherwise will be short-term capital gain or loss (with certain
exceptions to the characterization as capital gain if the New Note was acquired
at a market discount).
    
 
   
BACKUP WITHHOLDING
    
 
A holder of a New Note may be subject to backup withholding at the rate of 31%
with respect to interest paid on the New Note and proceeds from the sale,
exchange, redemption or retirement of the New Note, unless such holder (a) is a
corporation or comes within certain other exempt categories and, when required,
demonstrates that fact or (b) provides a correct taxpayer identification number,
certifies as to no loss of exemption from backup withholding and otherwise
complies with applicable requirements of the backup withholding rules. A holder
of a New Note who does not provide the Company with his correct taxpayer
identification number may be subject to penalties imposed by the IRS.
 
A holder of a New Note who is not a U.S. person will generally be exempt from
backup withholding and information reporting requirements, but may be required
to comply with certification and identification procedures in order to obtain an
exemption from backup withholding and information reporting.
 
Any amount paid as backup withholding will be creditable against the holder's
U.S. Federal income tax liability.
 
   
                              PLAN OF DISTRIBUTION
    
 
   
Each Participating Broker-Dealer that receives New Notes for its own account in
connection with the Exchange Offer must acknowledge that it will deliver a
prospectus in connection with any resale of such New Notes. This Prospectus, as
it may be amended or supplemented from time to time, may be used by
Participating Broker-Dealers during the period referred to below in connection
with resales of New Notes received in exchange for Old Notes if such Old Notes
were acquired by such Participating Broker-Dealers for their own accounts as a
result of market-making activities or other trading activities. The Company has
agreed that this Prospectus, as it may be amended or supplemented from time to
time, may be used by a Participating Broker-Dealer in connection with resales of
such New Notes for a period ending 180 days after the Expiration Date (subject
to extension under certain limited circumstances described herein) or, if
earlier, when all such New Notes have been disposed of by such Participating
Broker-Dealer. See "The Exchange Offer -- Resales of New Notes."
    
 
   
The Company will not receive any cash proceeds from the issuance of the New
Notes offered hereby. New Notes received by broker-dealers for their own
accounts in connection with the Exchange Offer may be sold from time to time in
one or more transactions in the over-the-counter market, in negotiated
transactions, through the writing of options on the New Notes or a combination
of such methods of resale, at market prices prevailing at the time of resale, at
prices related to such prevailing market prices or at negotiated prices. Any
such resale may be made directly to purchasers or to or through brokers or
dealers who may receive compensation in the form of commissions or concessions
from any such broker-dealer and/or the purchasers of any such New Notes. Any
broker-dealer that resells New Notes that were received by it for its own
account in connection with the Exchange Offer and any broker-dealer that
participates in a distribution of such New Notes may be deemed to be an
"underwriter" within the meaning of the Securities Act, and any profit on any
such resale of New Notes and any commissions or concessions received by any such
persons may be deemed to be underwriting compensation under the Securities Act.
The Letter of Transmittal states that by acknowledging that it will deliver and
by delivering a prospectus, a broker-dealer will not be deemed to admit that it
is an "underwriter" within the meaning of the Securities Act.
    
 
   
For a period of 180 days after the Expiration Date, the Company will promptly
send additional copies of this Prospectus and any amendment or supplement to
this Prospectus to any broker-dealer that requests such documents in the Letter
of Transmittal. The Company has agreed to pay all expenses incident to the
Exchange Offer other than commissions or concessions of any brokers or dealers
and will indemnify the holders of Old Notes (including any broker-dealers)
against certain liabilities, including liabilities under the Securities Act.
    
 
   
                                 LEGAL MATTERS
    
 
   
The validity of the issuance of the Notes will be passed upon for the Company by
Emens, Kegler, Brown, Hill & Ritter, Co., L.P.A., Columbus, Ohio.

                                    GLOSSARY
 
When the following terms are used in the text they have the meanings indicated.
 
MCF.  "Mcf" means thousand cubic feet. "Mmcf" means million cubic feet. "Bcf"
means billion cubic feet. "Tcf" means trillion cubic feet.
 
BBL.  "Bbl" means barrel. "MBbl" means thousand barrels. "MMBbl" means million
barrels. "BBbl" means billion barrels.
 
BOE.  "BOE" means barrels of oil equivalent, which are determined using the
ratio of one barrel of crude oil, condensate or natural gas liquids to six Mcf
of natural gas so that six Mcf of natural gas is referred to as one barrel of
oil equivalent or "BOE". "MBOE" means thousands of barrels of oil equivalent.
"MMBOE" means millions of barrels of oil equivalent.
 
CAPITAL EXPENDITURES.  "Capital Expenditures" means costs associated with
exploratory and development drilling (including exploratory dry holes);
leasehold acquisitions; seismic data acquisitions; geological, geophysical and
land-related overhead expenditures; delay rentals; producing property
acquisitions; and other miscellaneous capital expenditures.
 
COMPLETION COSTS.  "Completion Costs" means, as to any well, all those costs
incurred after the decision to complete the well as a producing well. Generally,
these costs include all costs, liabilities and expenses, whether tangible or
intangible, necessary to complete a well and bring it into production, including
installation of service equipment, tanks, and other materials necessary to
enable the well to deliver production.
 
DEVELOPMENT WELL.  A "Development Well" is a well drilled as an additional well
to the same reservoir as other producing wells on a lease, or drilled on an
offset lease not more than one location away from a well producing from the same
reservoir.
 
EXPLORATORY WELL.  An "Exploratory Well" is a well drilled in search of a new
and as yet undiscovered pool of oil or gas, or to extend the known limits of a
field under development.
 
FINDING COST.  "Finding Cost", expressed in dollars per BOE, is calculated by
dividing the amount of total capital expenditures related to acquisitions,
exploration and development costs (reduced by proceeds for any sale of oil and
gas properties) by the amount of total net reserves added or reduced as a result
of property acquisitions and sales, drilling activities and reserve revisions
during the same period.
 
FUTURE DEVELOPMENT COST.  "Future Development Cost" of proved nonproducing
reserves, expressed in dollars per BOE, is calculated by dividing the amount of
future capital expenditures related to development properties by the amount of
total proved non-producing reserves associated with such activities.
 
GROSS ACRES OR WELLS.  "Gross Acres or Wells" are the total acres or wells, as
the case may be, in which an entity has an interest, either directly or through
an affiliate.
 
LIFTING COSTS.  "Lifting Costs" are the expenses of lifting oil from a producing
formation to the surface, consisting of the costs incurred to operate and
maintain wells and related equipment and facilities, including labor costs,
repair and maintenance, supplies, insurance, production, severance and windfall
profit taxes.
 
NET ACRES OR WELLS.  A party's "Net Acres" or "Net Wells" are calculated by
multiplying the number of gross acres or gross wells in which that party has an
interest by the fractional interest of the party in each such acre or well.
 
PRODUCING PROPERTIES OR RESERVES.  "Producing Reserves" are Proved Developed
Reserves expected to be produced from existing completion intervals now open for
production in existing wells. "Producing Properties" are properties to which
Producing Reserves have been assigned by an independent petroleum engineer.
 
PROVED DEVELOPED RESERVES.  "Proved Developed Reserves" are Proved Reserves
which can be expected to be recovered through existing wells with existing
equipment and operating methods.
 
PROVED RESERVES.  "Proved Reserves" are the estimated quantities of crude oil,
natural gas and natural gas liquids which geological and engineering data
demonstrate with reasonable certainty to be recoverable in future years from
known oil and gas reservoirs under existing economic and operating conditions,
that is, on the basis of prices and costs as of the date the estimate is made
and any price changes provided for by existing conditions.
 
PROVED UNDEVELOPED RESERVES.  "Proved Undeveloped Reserves" are Proved Reserves
which can be expected to be recovered from new wells on undrilled acreage, or
from existing wells where a relatively major expenditure is required for
recompletion.
 
                                       74
<PAGE>   75
 
RESERVES.  "Reserves" means crude oil and natural gas, condensate and natural
gas liquids, which are net of leasehold burdens, are stated on a net revenue
interest basis, and are found to be commercially recoverable.
 
ROYALTY INTEREST.  A "Royalty Interest" is an interest in an oil and gas
property entitling the owner to a share of oil and gas production (or the
proceeds of the sale thereof) free of the costs of production.
 
STANDARDIZED MEASURE OF FUTURE NET CASH FLOWS.  The "Standardized Measure of
Future Net Cash Flows" is a method of determining the present value of Proved
Reserves. The future net revenues from Proved Reserves are estimated assuming
that oil and gas prices and production costs remain constant. The resulting
stream of revenues is then discounted at the rate of 10% per year to obtain a
present value.
 
3-D SEISMIC.  "3-D Seismic" is the method by which a three dimensional image of
the earth's subsurface is created through the interpretation of seismic data.
3-D surveys allow for a more detailed understanding of the subsurface than do
conventional surveys and contribute significantly to field appraisal,
development and production.
 
UNDEVELOPED ACREAGE.  "Undeveloped Acreage" is oil and gas acreage (including,
in applicable instances, rights in one or more horizons which may be penetrated
by existing wellbores, but which have not been tested) to which Proved Reserves
have not been assigned by independent petroleum engineers.

(the "New Notes"), upon the terms and subject to the conditions set forth in the
Prospectus dated July 12, 1996 (as the same may be amended or supplemented from
time to time, the "Prospectus"), receipt of which is acknowledged, and in this
Letter of Transmittal (which, together with the Prospectus, constitute the
"Exchange Offer"). The Exchange Offer has been registered under the Securities
Act of 1933, as amended (the "Securities Act").
    
 
     Subject to and effective upon the acceptance for exchange of all or any
portion of the Old Notes tendered herewith in accordance with the terms and
conditions of the Exchange Offer (including, if the Exchange Offer is extended
or amended, the terms and conditions of any such extension or amendment), the
undersigned hereby sells, assigns and transfers to or upon the order of the
Company all right, title and interest in and to such Old Notes as are being
tendered herewith. The undersigned hereby irrevocably constitutes and appoints
the Exchange Agent as its agent and attorney-in-fact (with full knowledge that
the Exchange Agent is also acting as agent of the Company in connection with the
Exchange Offer) with respect to the tendered Old Notes, with full power of
substitution (such power of attorney being deemed to be an irrevocable power
coupled with an interest), subject only to the right of withdrawal described in
the Prospectus, to (i) deliver Certificates for Old Notes to the Company
together with all accompanying evidences of transfer and authenticity to, or
upon the order of, the Company, upon receipt by the Exchange Agent, as the
undersigned's agent, of the New Notes to be issued in exchange for such Old
Notes, (ii) present Certificates for such Old Notes for transfer, and to
transfer the Old Notes on the books of the Company, and (iii) receive for the
account of the Company all benefits and otherwise exercise all rights of
beneficial ownership of such Old Notes, all in accordance with the terms and
conditions of the Exchange Offer.
 
     THE UNDERSIGNED HEREBY REPRESENTS AND WARRANTS THAT THE UNDERSIGNED HAS
FULL POWER AND AUTHORITY TO TENDER, EXCHANGE, SELL, ASSIGN AND TRANSFER THE OLD
NOTES TENDERED HEREBY AND THAT, WHEN THE SAME ARE ACCEPTED FOR EXCHANGE, THE
COMPANY WILL ACQUIRE GOOD, MARKETABLE AND UNENCUMBERED TITLE THERETO, FREE AND
CLEAR OF ALL LIENS, RESTRICTIONS, CHARGES AND ENCUMBRANCES, AND THAT THE OLD
NOTES TENDERED HEREBY ARE NOT SUBJECT TO ANY ADVERSE CLAIMS OR PROXIES. THE

NECESSARY IN ORDER TO MAKE THE STATEMENTS CONTAINED OR INCORPORATED BY REFERENCE

BROKER-DEALER OR THE COMPANY HAS GIVEN NOTICE THAT THE SALE OF THE NEW NOTES MAY

         FORMING PART OF THE TERMS AND CONDITIONS OF THE EXCHANGE OFFER
 
     1. DELIVERY OF LETTER OF TRANSMITTAL AND CERTIFICATES; GUARANTEED DELIVERY
PROCEDURES. This Letter of Transmittal is to be completed either if (a)
Certificates are to be forwarded herewith or (b) tenders are to be made pursuant
to the procedures for tender by book-entry transfer set forth in "The Exchange
Offer -- Procedures for Tendering Old Notes" in the Prospectus. Certificates, or
timely confirmation of a book-entry transfer of such Old Notes into the Exchange
Agent's account at DTC, as well as this Letter of Transmittal (or facsimile
thereof), properly completed and duly executed, with any required signature
guarantees, and any other documents required by this Letter of Transmittal, must
be received by the Exchange Agent at one of its addresses set forth herein on or
prior to the Expiration Date. Old Notes may be tendered in whole or in part in
the principal amount of $1,000 and integral multiples of $1,000.
 
   
     Holders who wish to tender their Old Notes and (i) whose Old Notes are not
immediately available or (ii) who cannot deliver their Old Notes, this Letter of
Transmittal and all other required documents to the Exchange Agent on or prior
to the Expiration Date or (iii) who cannot complete the procedures for delivery
by book-entry transfer on a timely basis, may tender their Old Notes by properly
completing and duly executing a Notice of Guaranteed Delivery pursuant to the

below); (ii) a properly completed and duly executed Notice of Guaranteed
Delivery, substantially in the form made available by the Company, must be
received by the Exchange Agent on or prior to the Expiration Date; and (iii) the

representing all tendered Old Notes, in proper form for transfer, together with
a Letter of Transmittal (or facsimile thereof), properly completed and duly
executed, with any required signature guarantees and any other documents
required by this Letter of Transmittal, must be received by the Exchange Agent
within five business days after the date of execution of such Notice of
Guaranteed Delivery, all as provided in "The Exchange Offer -- Procedures for

     The Notice of Guaranteed Delivery may be delivered by hand or transmitted
by facsimile or mail to the Exchange Agent, and must include a guarantee by an
Eligible Institution in the form set forth in such Notice. For Old Notes to be
properly tendered pursuant to the guaranteed delivery procedure, the Exchange

     THE METHOD OF DELIVERY OF CERTIFICATES, THIS LETTER OF TRANSMITTAL AND ALL
OTHER REQUIRED DOCUMENTS IS AT THE OPTION AND SOLE RISK OF THE TENDERING HOLDER
AND THE DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE EXCHANGE
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED,
PROPERLY INSURED, OR OVERNIGHT DELIVERY SERVICE IS RECOMMENDED. IN ALL CASES,
SUFFICIENT TIME SHOULD BE ALLOWED TO ENSURE TIMELY DELIVERY.
 
     The Company will not accept any alternative, conditional or contingent
tenders. Each tendering holder, by execution of a Letter of Transmittal (or
facsimile thereof), waives any right to receive any notice of the acceptance of
such tender.
 
     2. GUARANTEE OF SIGNATURES. No signature guarantee on this Letter of
Transmittal is required if:
 
          (i) this Letter of Transmittal is signed by the registered holder
     (which term, for purposes of this document, shall include any participant
     in DTC whose name appears on a security position listing as the owner of
     the Old Notes) of Old Notes tendered herewith, unless such holder(s) has
     completed either the box entitled "Special Issuance Instructions" or the
     box entitled "Special Delivery Instructions" above, or
 
          (ii) such Old Notes are tendered for the account of a firm that is an
     Eligible Institution.
 
     In all other cases, an Eligible Institution must guarantee the signature(s)
on this Letter of Transmittal. See Instruction 5.
 
     3. INADEQUATE SPACE. If the space provided in the box captioned
"Description of Old Notes" is inadequate, the Certificate number(s) and/or the
principal amount of Old Notes and any other required information should be
listed on a separate signed schedule which is attached to this Letter of
Transmittal.
 
   
     4. PARTIAL TENDERS AND WITHDRAWAL RIGHTS. Tenders of Old Notes will be
accepted only in the principal amount of $1,000 and integral multiples thereof.
If less than all the Old Notes evidenced by any Certificate submitted are to be
tendered, fill in the principal amount of Old Notes which are to be tendered in
the box entitled "Principal Amount of Old Notes Tendered (if less than all)." In
such case, new Certificate(s) for the remainder of the Old Notes that were
evidenced by your old Certificate(s) will only be sent to the holder of the Old
Note, promptly after the Expiration Date. All Old Notes represented by
Certificates delivered to the Exchange Agent will be deemed to have been
tendered unless otherwise indicated.

<PAGE>   84
 
     Except as otherwise provided herein, tenders of Old Notes may be withdrawn
at any time on or prior to the Expiration Date. In order for a withdrawal to be
effective on or prior to that time, a written, telegraphic, telex or facsimile
transmission of such notice of withdrawal must be timely received by the
Exchange Agent at one of its addresses set forth above or in the Prospectus on
or prior to the Expiration Date. Any such notice of withdrawal must specify the
name of the person who tendered the Old Notes to be withdrawn, the aggregate
principal amount of Old Notes to be withdrawn, and (if Certificates for Old
Notes have been tendered) the name of the registered holder of the Old Notes as
set forth on the Certificate for the Old Notes, if different from that of the
person who tendered such Old Notes. If Certificates for the Old Notes have been
delivered or otherwise identified to the Exchange Agent, then prior to the
physical release of such Certificates for the Old Notes, the tendering holder
must submit the serial numbers shown on the particular.
 
     Certificates for the Old Notes to be withdrawn and the signature on the
notice of withdrawal must be guaranteed by an Eligible Institution, except in
the case of Old Notes tendered for the account of an Eligible Institution. If
Old Notes have been tendered pursuant to the procedures for book-entry transfer
set forth in "The Exchange Offer -- Procedures for Tendering Old Notes," the
notice of withdrawal must specify the name and number of the account at DTC to
be credited with the withdrawal of Old Notes, in which case a notice of
withdrawal will be effective if delivered to the Exchange Agent by written,
telegraphic, telex or facsimile transmission. Withdrawals of tenders of Old
Notes may not be rescinded. Old Notes properly withdrawn will not be deemed
validly tendered for purposes of the Exchange Offer, but may be retendered at
any subsequent time on or prior to the Expiration Date by following any of the
procedures described in the Prospectus under "The Exchange Offer -- Procedures
for Tendering Old Notes."
 
     All questions as to the validity, form and eligibility (including time of
receipt) of such withdrawal notices will be determined by the Company, in its
sole discretion, whose determination shall be final and binding on all parties.
Neither the Company, any affiliates or assigns of the Company, the Exchange
Agent nor any other person shall be under any duty to give any notification of
any irregularities in any notice of withdrawal or incur any liability for
failure to give any such notification. Any Old Notes which have been tendered
but which are withdrawn will be returned to the holder thereof without cost to
such holder promptly after withdrawal.
 
     5. SIGNATURES ON LETTER OF TRANSMITTAL, ASSIGNMENTS AND ENDORSEMENTS. If
this Letter of Transmittal is signed by the registered holder(s) of the Old
Notes tendered hereby, the signature(s) must correspond exactly with the name(s)
as written on the face of the Certificate(s) without alteration, enlargement or
any change whatsoever.
 
     If any of the Old 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 Old Notes are registered in different name(s) on several
Certificates, it will be necessary to complete, sign and submit as many separate
Letters of Transmittal (or facsimiles thereof) as there are different
registrations of Certificates.
 
     If this Letter of Transmittal or any Certificates 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 must submit proper evidence
satisfactory to the Company, in its sole discretion, of such persons' authority
to so act.
 
   
     When this Letter of Transmittal is signed by the registered owner(s) of the
Old Notes listed and transmitted hereby, no endorsement(s) of Certificate(s) or
separate bond power(s) are required unless New Notes are to be issued in the
name of a person other than the registered holder(s). Signature(s) on such
Certificate(s) or bond power(s) must be guaranteed by an Eligible Institution.
    
 
     If this Letter of Transmittal is signed by a person other than the
registered owner(s) of the Old Notes listed, the Certificates must be endorsed
or accompanied by appropriate bond powers, signed exactly as the name or names
of the registered owner(s) appear(s) on the Certificates, and also must be
accompanied by such opinions of counsel, certifications and other information as
the Company or the Trustee for the Old Notes may require in accordance with the
restrictions on transfer applicable to the Old Notes. Signatures on such
Certificates or bond powers must be guaranteed by an Eligible Institution.
 
     6. SPECIAL ISSUANCE AND DELIVERY INSTRUCTIONS. If New Notes are to be
issued in the name of a person other than the signer of this Letter of
Transmittal, or if New Notes are to be sent to someone other than the signer of
this Letter of Transmittal or to an address other than that shown above, the
appropriate boxes on this Letter of Transmittal should be completed.
Certificates for Old Notes not exchanged will be returned by mail or, if
tendered by book-entry transfer, by crediting the account indicated above
maintained at DTC. See Instruction 4.
 
     7. IRREGULARITIES. The Company will determine, in its sole discretion, all
questions as to the form of documents, validity, eligibility (including time of
receipt) and acceptance for exchange of any tender of Old Notes, which
determination shall be final and binding on all parties. The Company reserves
the absolute right to reject any and all tenders determined by it not to be in
proper form or the acceptance of which, or exchange for, may, in the view of
counsel to the Company, be unlawful. The Company also reserves the absolute
right, subject to applicable law, to waive any of the conditions of the Exchange
Offer set forth in the Prospectus under "The Exchange Offer -- Certain
Conditions to the Exchange Offer" or any conditions or irregularity in any
tender of Old Notes of any particular holder whether or not similar conditions
or irregularities are waived in the case of other holders.
 
     The Company's interpretation of the terms and conditions of the Exchange
Offer (including this Letter of Transmittal and the instructions hereto) will be
final and binding. No tender of Old Notes will be deemed to have been validly
made until all irregularities with respect to such tender have been cured or
waived. Neither the Company, any affiliates or assigns of the Company, the
Exchange
 
                                        8

Agent, nor any other person shall be under any duty to give notification of any
irregularities in tenders or incur any liability for failure to give such
notification.
 
     8. QUESTIONS, REQUESTS FOR ASSISTANCE AND ADDITIONAL COPIES. Questions and
requests for assistance may be directed to the Exchange Agent at its address and
telephone number set forth on the front of this Letter of Transmittal.
Additional copies of the Prospectus, the Notice of Guaranteed Delivery and the
Letter of Transmittal may be obtained from the Exchange Agent or from your
broker, dealer, commercial bank, trust company or other nominee.
 
   
     9. 31% BACKUP WITHHOLDING; SUBSTITUTE FORM W-9. Under U.S. Federal income
tax law, a holder whose tendered Old Notes are accepted for exchange is required
to provide the Exchange Agent with such holder's correct taxpayer identification
number ("TIN") on Substitute Form W-9 below. If the Exchange Agent is not
provided with the correct TIN, the Internal Revenue Service (the "IRS") may
subject the holder or other payee to a $50 penalty. In addition, payments to
such holders or other payees with respect to Old Notes exchanged pursuant to the
Exchange Offer may be subject to 31% backup withholding.
    
 
     The box in Part 2 of the Substitute Form W-9 may 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 2 is checked, the
holder or other payee must also complete the Certificate of Awaiting Taxpayer
Identification Number below in order to avoid backup withholding.
Notwithstanding that the box in Part 2 is checked and the Certificate of
Awaiting Taxpayer Identification Number is completed, the Exchange Agent will
withhold 31% of all payments made prior to the time a properly certified TIN is
provided to the Exchange Agent. The Exchange Agent will retain such amounts
withheld during the 60 day period following the date of the Substitute Form W-9.
If the holder furnishes the Exchange Agent with its TIN within 60 days after the
date of the Substitute Form W-9, the amounts retained during the 60 day period
will be remitted to the holder and no further amounts shall be retained or
withheld from payments made to the holder thereafter. If, however, the holder
has not provided the Exchange Agent with its TIN within such 60 day period,
amounts withheld will be remitted to the IRS as backup withholding. In addition,
31% of all payments made thereafter will be withheld and remitted to the IRS
until a correct TIN is provided.
 
     The holder is required to give the Exchange Agent the TIN (e.g., social
security number or employer identification number) of the registered owner of
the Old Notes or of the last transferee appearing on the transfers attached to,
or endorsed on, the Old Notes. If the Old Notes are registered in more than one
name or are 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.
 
     Certain holders (including, among others, corporations, financial
institutions and certain foreign persons) may not be subject to these backup
withholding and reporting requirements. Such holders should nevertheless
complete the attached Substitute Form W-9 below, and write "exempt" on the face
thereof, to avoid possible erroneous backup withholding. A foreign person may
qualify as an exempt recipient by submitting a properly completed IRS Form W-8,
signed under penalties of perjury, attesting to that holder's exempt status.
Please consult the enclosed "Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9" for additional guidance on which
holders are exempt from backup withholding.
 
     Backup withholding is not an additional U.S. Federal income tax. Rather,
the U.S. Federal income tax liability of a person 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.
 
     10. LOST, DESTROYED OR STOLEN CERTIFICATES. If any Certificate(s)
representing Old Notes have been lost, destroyed or stolen, the holder should
promptly notify the Exchange Agent. The holder will then be instructed as to the
steps that must be taken in order to replace the Certificate(s). This Letter of
Transmittal and related documents cannot be processed until the procedures for
replacing lost, destroyed or stolen Certificate(s) have been followed.
 
     11. SECURITY TRANSFER TAXES. Holders who tender their Old Notes for
exchange will not be obligated to pay any transfer taxes in connection
therewith. If, however, New Notes are to be delivered to, or are to be issued in
the name of, any person other than the registered holder of the Old Notes
tendered, or if a transfer tax is imposed for any reason other than the exchange
of Old Notes in connection with the Exchange Offer, then the amount of any such
transfer tax (whether imposed on the registered holder or any other persons)
will be payable by the tendering holder. If satisfactory evidence of payment of
such taxes or exemption therefrom is not submitted with the Letter of
Transmittal, the amount of such transfer taxes will be billed directly to such
tendering holder.
