1990-1 PARTNERSHIP

         Common Stock and Warrants of Benton are being offered on a
proportionate basis to owners of Partnership Units in the 1990-1 Partnership, on
the basis of $5,000 original investment interest (the "1990-1 Units") in
exchange for their 1990-1 Units at the rate of 77 shares of Common Stock and
Warrants to purchase 249 shares of Common Stock with an exercise price of $12.37
per share for each 1990-1 Unit. In connection with the Exchange Offer, a
proposal (the "1990-1 Proposal") is being submitted to the Investors in the
1990-1 Partnership to amend the partnership agreement of the 1990-1 Partnership
(the "1990-1 Partnership Agreement") to provide for the transfer of all assets
and liabilities of the 1990-1 Partnership to Benton in exchange for 109,277
shares of Common Stock and 353,378 Warrants and the pro rata distribution of the
Common Stock and Warrants in liquidation of the 1990-1 Partnership. EACH
INVESTOR IN THE 1990-1 PARTNERSHIP WHO TENDERS HIS 1990-1 UNITS WILL, BY THAT
TENDER, CONSENT TO THE 1990-1 PROPOSAL.

1991-1 PARTNERSHIP

         Common Stock and Warrants of Benton are being offered on a
proportionate basis to owners of Partnership Units in the 1991-1 Partnership, on
the basis of $5,000 original investment interest (the "1991-1 Units") in
exchange for their 1991-1 Units at the rate of 92 shares of Common Stock and
Warrants to purchase 282 shares of Common Stock with an exercise price of $12.37
per share for each 1991-1 Unit. In connection with the Exchange Offer, a
proposal (the "1991-1 Proposal") is being submitted to the Investors in the
1991-1 Partnership to amend the partnership agreement of the 1991-1 Partnership
(the "1991-1 Partnership Agreement") to provide for the transfer of all assets
and liabilities of the 1991-1 Partnership to Benton in exchange for 25,927
shares of Common Stock and 79,472 Warrants and the pro rata distribution of the
Common Stock and Warrants in liquidation of the 1991-1 Partnership. EACH
INVESTOR IN THE 1991-1 PARTNERSHIP WHO TENDERS HIS 1991-1 UNITS WILL, BY THAT
TENDER, CONSENT WITH THE 1991-1 PROPOSAL.

         ADOPTION OF EACH OF THE PROPOSALS REQUIRES THE CONSENT OF INVESTORS OF
SUCH PARTNERSHIP HOLDING 75% OF THE PARTNERSHIP UNITS. BENTON OIL AND GAS
COMPANY, IN ADDITION TO BEING MANAGING GENERAL PARTNER OF THE THREE
PARTNERSHIPS, OWNS 2.8182 1989-1 UNITS, 14.192 1990-1 UNITS AND 2.8182 1991-1
UNITS AND WILL VOTE SUCH UNITS THE SAME AS A MAJORITY OF INVESTORS VOTE THEIR
UNITS. INVESTORS WILL RECEIVE THE CONSIDERATION SET FORTH HEREIN, AND THE
RESPECTIVE PARTNERSHIP WILL BE DISSOLVED.

         ASSUMING CONSUMMATION OF THE EXCHANGE OFFER, ALL OF THE INVESTORS IN A
PARTNERSHIP WHICH HAS APPROVED THE PROPOSAL PRESENTED TO SUCH PARTNERSHIP,
WHETHER OR NOT THEY TENDER THEIR UNITS AND THUS VOTE IN FAVOR OF THE PROPOSAL,
WILL RECEIVE THE SAME NUMBER OF SHARES OF COMMON STOCK AND WARRANTS AS THEY
WOULD HAVE RECEIVED HAD THEY TENDERED THEIR PARTNERSHIP UNITS AND THE RESPECTIVE
PARTNERSHIP WILL BE DISSOLVED.

         THE EXCHANGE OFFER INVOLVES VARIOUS RISKS THAT SHOULD BE CONSIDERED BY
INVESTORS. SEE "RISK FACTORS AND MATERIAL CONSIDERATIONS," BEGINNING ON PAGE 34
OF THIS PROSPECTUS. IN PARTICULAR, INVESTORS SHOULD CONSIDER THE FOLLOWING
FACTORS:

           *   INVESTORS HAD RECEIVED CASH DISTRIBUTIONS FROM THE PARTNERSHIPS,
               BUT WILL RECEIVE NO CASH DISTRIBUTIONS OR DIVIDENDS IN THE
               FORESEEABLE FUTURE FROM BENTON.



<PAGE>   7

           *   THE MARKET PRICE OF THE COMMON STOCK COULD DECLINE BELOW THE
               MARKET PRICE USED FOR CALCULATION OF THE RESPECTIVE EXCHANGE
               RATES, EXPOSING INVESTORS TO A REDUCED RETURN ON THEIR
               INVESTMENT.

           *   THE EXCHANGE VALUE OF THE PARTNERSHIP UNITS WAS DETERMINED BY
               BENTON, WHICH HAS INHERENT CONFLICTS OF INTEREST, AND MAY NOT
               REFLECT THE VALUE OF THE NET ASSETS OF THE RESPECTIVE PARTNERSHIP
               IF SOLD TO AN UNAFFILIATED THIRD PARTY IN AN ARM'S LENGTH
               TRANSACTION.

           *   BENTON HAS ATTRIBUTED A PRESENT VALUE TO THE WARRANTS, USING THE
               BLACK-SCHOLES OPTION PRICING MODEL. HOWEVER, THE ACTUAL VALUE, IF
               ANY, A HOLDER MAY REALIZE FROM THE WARRANTS WILL DEPEND ON THE
               EXCESS OF THE MARKET PRICE OF THE COMMON STOCK OVER THE EXERCISE
               PRICE OF THE WARRANT ON THE DATE THE WARRANT IS EXERCISED.

           *   BENTON'S DETERMINATIONS OF THE RESPECTIVE EXCHANGE VALUES WERE
               BASED PRIMARILY ON THE ESTIMATED PRESENT VALUE OF EACH
               PARTNERSHIP'S PROVED OIL AND GAS RESERVES, WHICH INVOLVES MANY
               UNCERTAINTIES AND COULD RESULT IN AN UNDERVALUATION OF
               PARTNERSHIP UNITS, AND AN INDEPENDENT OFFER FOR THE PURCHASE OF
               SUBSTANTIALLY ALL OF THE ASSETS OF EACH OF THE PARTNERSHIPS.

           *   THE ALTERNATIVES OF CONTINUING THE PARTNERSHIPS OR LIQUIDATING
               THEIR ASSETS COULD POTENTIALLY BE MORE BENEFICIAL TO INVESTORS
               THAN THE EXCHANGE OFFER.

           *   NO INDEPENDENT REPRESENTATIVE WAS ENGAGED TO REPRESENT THE
               UNAFFILIATED INVESTORS IN NEGOTIATING THE TERMS OF THE EXCHANGE
               OFFER, WHICH MAY BE INFERIOR TO THOSE THAT COULD HAVE BEEN
               NEGOTIATED BY AN INDEPENDENT REPRESENTATIVE.

           *   INVESTORS HAVE NO DISSENTER'S RIGHTS IN THE EXCHANGE OFFER,
               OTHER THAN LIMITED DISSENTERS' RIGHTS FOR CALIFORNIA RESIDENTS,
               AND THEREFORE CANNOT ELECT TO RECEIVE CASH FOR THEIR PARTNERSHIP
               UNITS.

           *   OWNERSHIP OF COMMON STOCK MAY INVOLVE GREATER RISK THAN AN
               INVESTMENT IN THE PARTNERSHIP UNITS BECAUSE OF BENTON'S BROADER
               OPERATIONS, INCLUDING FOREIGN OPERATIONS, AND ITS USE OF DEBT TO
               FINANCE ONGOING OPERATIONS.

           *   FUTURE EQUITY OFFERINGS BY BENTON COULD POTENTIALLY BE DILUTIVE
               TO INVESTORS HOLDING COMMON STOCK OR WARRANTS.

         Benton has determined that the Total Exchange Value of all (i) 1989-1
Units is $364,226 or $1,292 per 1989-1 Unit; (ii) 1990-1 Units is $2,553,119 or
$1,799 per 1990-1 Unit; and (iii) 1991-1 Units is $591,623 or $2,099 per 1991-1
Unit (collectively, the "Exchange Values"). The number of shares of Common Stock
offered in exchange for Partnership Units has been determined by dividing the
estimated cash proceeds from the offer for the purchase of the Umbrella Point
Field, as described herein, plus the estimated fair value of the remaining
tangible Partnership assets by a Common Stock price of $12.37, subject to
rounding adjustments. The Common Stock price of $12.37 is the closing price of
the Common Stock on the National Association of Securities Dealers,
Inc.-National Market System ("NASDAQ-NMS") on July 17, 1995. The number of
Warrants to be issued in exchange for Partnership Units has been determined by
dividing the estimated value of the General Intangibles of the Partnership, as
described herein, by the estimated present value per Warrant. Benton has used
the Black-Scholes 




<PAGE>   8

option pricing model to calculate the present value of the Warrants, which
yielded a present value of $3.38 per Warrant. The Warrants are exercisable at a
price of $12.37 per share and will expire three years from the date of issuance.
See "Method of Determining Exchange Values." On July 24, 1995, the last reported
sales prices of the Common Stock, as reported on NASDAQ-NMS, was $12.375.

         The Exchange may be withdrawn at any time prior to its scheduled
expiration date if Benton determines that a material change affecting the
Partnerships or the Company has occurred. THE EXCHANGE WILL ONLY BE CONSUMMATED
FOR THOSE PARTNERSHIPS IN WHICH THE PROPOSAL HAS BEEN APPROVED BY THE INVESTORS.
The assets and liabilities of any Partnership which approves the respective
Proposal and adopts the Exchange Offer will be transferred to Benton effective
as of December 31, 1994 (the "Effective Date").

THE EXCHANGE OFFER EXPIRES AT 5:00 P.M. PACIFIC TIME ON ____________, 1995
UNLESS EXTENDED.
             ______________________________________________________

                                     SUMMARY

         The following is a brief summary of certain information contained
elsewhere in this Prospectus. This summary is not intended to be a complete
description of the matters covered in this Prospectus and is subject to and
qualified in its entirety by reference to the more detailed information and
financial statements contained elsewhere in this Prospectus, including the
Supplement and Exhibits hereto and the documents incorporated herein by
reference. Investors are urged to read carefully the entire Prospectus,
including the Supplement and Exhibits. See Glossary included elsewhere in this
Prospectus for definitions of certain oil and gas terms.

                                   THE PARTIES

         BENTON OIL AND GAS COMPANY

         Benton Oil and Gas Company ("Benton" or the "Company") is primarily
engaged in the development and production of oil and gas properties. The
Company's operations are focused on the eastern region of Venezuela, the Gulf
Coast region of Louisiana and the West Siberia region of Russia. Benton's
business strategy is to seek new reserves in areas of low geologic risk and to
exploit underdeveloped existing oil and gas fields. The Company implements the
exploitation strategy through the in-house design and interpretation of 3-D
seismic surveys and through workovers, recompletions, redrilling and exploration
and development drilling.

         Internationally, the Company seeks projects with significant reserve
potential in areas with low geologic risk and known proved reserves where, in
certain situations, the Company can add value by employing modern exploration,
drilling, completion and production techniques. To reduce risk, control costs,
and facilitate local transactions, the Company has formed ventures with local
foreign partners.

         Domestically, the Company integrates 3-D seismic technology with
subsurface geologic data from previously drilled wells. This geophysical
evaluation enables the Company to discover previously undetected reserves in
existing fields. The Company believes that it enjoys a competitive advantage in
finding and developing reserves on an economic basis because of its
concentration on 3-D seismic technology, the training and qualifications of its
in-house technical team and the practical experience and knowledge which this
team has acquired over past years. The Company's recognized technical expertise
has afforded it access to projects it otherwise would not have enjoyed.

         In the ordinary course of its business, the Company continues to
evaluate acquisition, joint venture and other opportunities that would enable it
to further its business strategy.

Principal Areas of Activity

         The following table summarizes the Company's proved reserves at
December 31, 1994 by principal geographic area:

(1)      All Venezuelan reserves are attributable to an operating service
         agreement between Benton-Vinccler and Lagoven, S.A. under which all
         mineral rights are owned by the Government of Venezuela.

(2)      The Company's engineering estimates, which have been prepared by the
         Company and audited by Huddleston & Co., Inc., independent petroleum
         engineers, indicate that approximately 18 Bcf of natural gas reserves
         (net to the Company's interest) will be developed and produced in
         association with the development and production of the Company's proved
         undeveloped oil reserves in Russia. The Company expects that, due to
         current market conditions, it will initially reinject or flare such
         associated natural gas production and, accordingly, no future net
         reserves have been assigned to these reserves. Under the joint venture
         agreement, such reserves are owned by the Company in the same
         proportion as all other hydrocarbons in the North Gubkinskoye Field,
         and subsequent changes in conditions could result in the assignment of
         value to these reserves.

VENEZUELA

         In July 1992, the Company and Vinccler, a Venezuelan construction and
engineering company, signed an operating service agreement with Lagoven, S.A.
("Lagoven"), an affiliate of the national oil company, Petroleos de Venezuela
S.A. ("PDVSA"), to reactivate and further develop the Uracoa, Bombal and
Tucupita Fields (the "Fields"), which are a part of the South Monagas Unit (the
"Unit"). Of the 230 foreign companies responding to Venezuela's initial call for
indications of interest, the Company was one of three foreign companies
ultimately awarded an operating service agreement to reactivate existing fields
by PDVSA. The Company was the first U.S. company since 1976 to be granted such
an oil field development contract in Venezuela.

         Under the terms of the operating service agreement, Benton-Vinccler,
the Company's 80% owned Venezuelan subsidiary, 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. 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. During each quarter of 1994, the adjusted maximum total fee was less
than the adjusted 



                                       2
<PAGE>   16

operating fee, resulting in no capital recovery fee. The Company cannot predict 
the extent to which future maximum total fee adjustments will provide for a 
capital recovery fee.

         The Unit is in the southeastern part of the state of Monagas in eastern
Venezuela. The Unit is approximately 51 miles long, eight miles wide and
consists of 157,843 acres, of which the Fields comprise approximately one-half.
Benton-Vinccler intends to explore the remaining portions of the Unit for
possible development activities. At December 31, 1994, Proved Reserves
attributable to the Company's Venezuelan operations were 60.7 MMBOE, which
represented 75% of the Company's Proved Reserves, all of which were located in
the Uracoa and Bombal Fields. Benton-Vinccler has reactivated fifteen previously
drilled wells and completed 21 new wells using modern drilling and completion
techniques that have not previously been utilized on the Fields. Benton-Vinccler
also has installed specialized production facilities commonly used in heavy oil
production in the United States but not previously utilized extensively in
Venezuela to process crude oil of similar gravity or quality. Benton-Vinccler
commenced production during the second quarter of 1993. During 1994, average
daily production steadily increased from 3,400 Bbl of oil during the first
quarter to 6,700 Bbl in the second quarter, 7,200 Bbl in the third quarter and
10,200 Bbl in the fourth quarter. Currently, 36 wells are producing
approximately 14,000 Bbl of oil per day.

        Benton-Vinccler intends to completely develop the Uracoa Field by
drilling approximately 90 to 100 wells. It also plans to reactivate and
completely develop the Bombal Field by drilling approximately 25-30 wells and
to evaluate the potential of the Tucupita Field in 1996 by testing 3 wells.
During the first quarter of 1995, Benton-Vinccler shot 150 kilometers of
seismic and is currently interpreting the data. Following the initial
interpretations of such seismic, Benton-Vinccler may also 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. Budget and
development plans submitted by Benton-Vinccler have been approved by Lagoven in
the past and the Company believes that such approvals will be granted in the
future.

         In June 1994, the Venezuelan government, amid economic uncertainties
and bank crises, suspended certain constitutional rights and implemented certain
exchange and price controls. Currently, exchange and price controls remain in
place, with no indication of when such controls will be lifted. To date, neither
the current economic uncertainties nor the exchange and price controls have had
an adverse effect on the Company's operations in Venezuela. The Company has
applied for insurance to cover the risk of currency repatriation and
inconvertibility, expropriation and interference with operations for its
Venezuelan operations with OPIC, an agency of the United States government.
While OPIC has indicated that such insurance is available, there can be no
assurance that the Company will be able to obtain this insurance.

UNITED STATES

Louisiana

         The Company has successfully pursued acquisition and joint venture
opportunities in the United States which have become more readily available as
major oil and gas companies continue to consolidate operations and focus
exploration and development activities outside the United States. At December
31, 


                                       3
<PAGE>   17
1994, Proved Reserves of the Company attributable to the United States were
2.9 MMBOE, which represented 4% of the Company's Proved Reserves. Substantially
all of the Company's domestic activities are located in the Louisiana Gulf Coast
at the West Cote Blanche Bay, Rabbit Island and Belle Isle Fields. The Company,
Texaco, Inc. ("Texaco") and Oryx Energy Company ("Oryx") are currently producing
from and further developing 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 has 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.

         Several key elements common to the three fields include their discovery
and initial development prior to World War II, peak production periods occurring
prior to 1960, extremely complex geology, relatively little modern exploration
technology being applied, and long-term natural gas sales contracts at prices
below $0.30 per Mcf which discouraged any significant drilling and development
until the contracts expired in the last few years.

         The state leases relating to these fields were subject to litigation
between Texaco and the State of Louisiana. Although the Company was not a party
to this litigation, its interests in the three fields were subject to the
litigation. In February 1994, Texaco and the State entered into a Global
Settlement Agreement. As a result of this agreement, Texaco committed to certain
acreage development and drilling obligations which may affect the Company and
certain of its Louisiana properties. The Company believes that the settlement
should have no effect on its proved reserves and will have no material adverse
effect on the Company.

         West Cote Blanche Bay Field

         The West Cote Blanche Bay Field is located on 5,892 acres in a shallow
bay in St. Mary Parish, approximately 125 miles southwest of New Orleans with
water depths averaging seven to eight feet. The field was discovered in 1938 by
Texaco, which continues to operate the field. The Company believes that, at
approximately 3.5 miles long and two miles wide, the West Cote Blanche Bay Field
contains one of the largest salt domes in the Gulf Coast. More than 300 separate
oil and gas reservoirs have been identified by Texaco and the Company from a
total of approximately 680 wellbores in 180 different sandstone formations, at
depths from 1,700 to 13,000 feet. At December 31, 1994, the field had
cumulatively produced over 181 MMBbl of oil and 225 Bcf of natural gas.

         Since the Company's first acquisition of an interest in the West Cote
Blanche Bay Field, it has worked with Texaco in the technical evaluation of the
field. Until late 1994, the prospect evaluations covered all depths and included
the drilling wells and a substantial number of recompletions and replacement
wells in oil reservoirs at depths of 2,000 to 10,500 feet. As a result of
ongoing evaluation, in late 1994 the Company decided to focus almost exclusively
on exploitation of gas and oil reservoirs at depths below 10,000 feet, utilizing
the results of the 3-D seismic interpretations. To mitigate the risk of
concentrating on deeper, more expensive wells, the Company sold approximately
25% of its working interest to Tenneco. Also, in March 1995, the Company and its
affiliates and Tenneco sold their interests in the shallower oil depths (above
approximately 10,575 feet) to WRT Energy Corporation, another working interest
owner in the field.


                                       4

         Rabbit Island Field

         Rabbit Island is located in state waters in Iberia and St. Mary
Parishes, approximately 95 miles southwest of New Orleans. The dome was
discovered in 1939 by Texaco which continues to operate the field. Compared to
West Cote Blanche Bay, on whose 5,892 acres more than 800 wells have been
drilled, just over 200 wells have been drilled on the 27,909 acres of the Rabbit
Island Field. Cumulative production through December 31, 1994 was 48 MMBbl of
oil and 1.2 Tcf of gas from 51 productive zones.

         In 1992, the Company signed an agreement with Texaco to fund and
conduct a 3-D seismic program covering approximately 105 square miles over the
Rabbit Island project area. The estimated cost to the Company of this program is
approximately $6.0 million, substantially all of which has been expended. The
seismic survey has been shot, processed and is currently being interpreted.

         Pursuant to the agreement, the Company may drill five wells over a
period of up to five years. As identified below, the first well has been
drilled. Assuming the remaining four wells are drilled in accordance with the
terms set forth in the agreement, the Company will earn a 50% working interest
in the entire field (other than among other things, wells previously drilled by
Texaco). The first well in the drilling program was successfully completed in
January 1995 and is currently producing approximately 9.5 MMcf of natural gas
per day. The Company expects to drill up to four additional wells during 1995 at
Rabbit Island at a cost of up to $4 million.

         Certain of the Company's rights and 50% of its interest in the Field
were sold to Tenneco in July 1993. In May, 1995, the Company and Tenneco signed
an agreement in principle with Texaco to expand the acreage under the Rabbit
Island Field agreement by 10,452 acres in exchange for an increase in the number
of earning wells to be drilled by the Company from 5 to 8 wells.

         Belle Isle Field

         The Belle Isle Field is located on the shore of the Atchafalaya Bay,
approximately 75 miles southwest of New Orleans, in St. Mary Parish. The field
was discovered in 1941 and developed by Sun Oil Company. Currently, 12,000 acres
on the north portion of the field are operated by Oryx, and 6,400 acres on the
south portion of the field are operated by Apache Corporation (previously
operated by Texaco). As of December 31, 1994, the Belle Isle Field had
cumulatively produced over 50 MMBbl of oil and 1 Tcf of natural gas.

         In 1990, the Company reached an agreement with Oryx to shoot a 3-D
seismic survey over its portion of the field. Pursuant to the agreement, upon
completing the survey and processing the seismic data, Oryx granted the Company
the right to participate in the drilling of wells on Oryx's portion of the field
and the Company will have a 33% working interest in any well so drilled from the
top of the deep sands known as the "Rob L Sands" (at a depth of 12,500 feet) and
below. Under the agreement, up to two exploratory wells and two development
wells may be drilled in any calendar year. In the event that Oryx decides to
solicit the participation of a third party in certain drilling operations above
the Rob L Sands, 


                                       5
<PAGE>   19
Oryx has granted the Company a right of first refusal to participate in such 
drilling and receive a 33% working interest in the resulting wells.

         In 1991, the Company reached an agreement with Texaco to evaluate 5,500
acres on the southern portion of the field by extending the 3-D seismic survey.
Pursuant to this agreement, upon the Company's completion of the seismic survey
and its drilling of an initial test well in accordance with the terms set forth
in the agreement, Texaco assigned to the Company a 50% working interest in its
entire 6,400 acre portion of the Belle Isle Field (other than, among other
things, existing wells previously drilled by Texaco).

         In 1992, the Company completed a 55.75 square mile 3-D seismic survey
over the Belle Isle Field, thereby satisfying the survey obligations that are
prerequisites for earning working interests in the Texaco portion of the Field
and the Oryx wells. The survey was reprocessed in 1993 and is being evaluated on
an ongoing basis. In 1993, the Company satisfied the drilling requirements under
the agreement with Texaco, thereby earning its 50% working interest on the
Texaco portion of the field.

         In October 1994, the Company completed the Belle Isle State Lease 340
No. 1 well. This well is currently producing at rates of approximately 6 MMcf of
natural gas per day. The Company has until September 1, 1997 to exercise its
right to participate in any future Oryx wells. If the Company has participated
in the drilling of a producing well by that time, the Company's right to
participate in future wells will continue. Certain of the Company's rights and
50% of its interest in the Field were sold to Tenneco in July 1993.

         In January 1995 Texaco sold its interest in Belle Isle to Apache
Corporation. The Company is unable at this time to assess the impact on the
development of the field as a result of this sale.

         Tenneco Agreements

         In June 1993, the Company entered into an agreement with Tenneco which
provided for payments to the Company of approximately $6.7 million in exchange
for a 50% interest in the Company's operations at the Rabbit Island and Belle
Isle Fields. The agreement also provided Tenneco with a five year option to
participate on a promoted basis as a 50% partner in any future ventures that the
Company acquired in the Gulf Coast area, except for the West Cote Blanche Bay
Field. The Company also has granted an option in favor of Tenneco to purchase,
at a market price, all of the Company's gas produced from the Gulf Coast.
Tenneco has exercised its option to purchase the Company's share of natural gas
production from all three fields.

         In November 1994, the Company sold to Tenneco a 10.8% working interest
(24.9% of the Company's 43.3% working interest) in the West Cote Blanche Bay
Field for approximately $5.8 million and future consideration of up to $3.7
million.

         WRT Agreement

         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.

OTHER PROPERTIES

         At December 31, 1994, the Company had proved reserves of 180 MBOE and 6
MBOE in the Umbrella Point Field in Texas and certain fields in Louisiana and
Mississippi, respectively. In July 1995, the Company sold its interest in the
Umbrella Point Field.

         Actual exploration and development activities in the United States
could ultimately vary from those currently projected by the Company, depending,
among other factors, on the availability of drilling rigs, the availability of
financing, the success of the activities and the continued concurrence of
working interest partners as to the timing and extent of such activities.

RUSSIA

         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. The Company's partners are the official exploration and
production bodies which have been discovering and operating fields in the region
covered by the joint venture for many years, and which have access to pipelines,
railroads and other vital infrastructure. GEOILBENT develops, produces and
markets oil and condensate from the North Gubkinskoye Field in the West Siberia
region of Russia, 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 zones) and is
surrounded by large proven fields. Before commencement of GEOILBENT's
operations, North Gubkinskoye was one of the largest non-producing fields in the
region. At December 31, 1994, the Proved Reserves attributable to the North
Gubkinskoye Field were 17.5 MMBOE, which represented 22% of the Company's Proved
Reserves.

         During the third quarter of 1992, GEOILBENT commenced initial
operations which included the construction of a 37 mile oil pipeline and
installation of temporary production facilities. Completed in April 1993, with a
design capacity of 75,000 Bbl of oil per day, the pipeline transports oil from
the North Gubkinskoye Field south to the main Russian oil pipeline network. The
venture has been exporting oil since the fourth quarter of 1993.

         GEOILBENT identified nine previously existing delineation wells that
were capable of being reentered and placed these on production. These
delineation wells were not originally intended by Purneftegasgeologia to be
commercial producers. Therefore, completion procedures for optimum production
were not employed. The Company believes that production rates from future wells
using western completion technologies will be significantly greater. GEOILBENT
has commenced drilling a series of development wells in the North Gubkinskoye
Field. Three Russian drilling rigs are drilling development wells offsetting
previously drilled exploration wells.

         GEOILBENT is utilizing Russian equipment and personnel whenever
feasible. Supervision is provided jointly by an American and Russian management
team. Russian equipment, including Russian rigs, are being upgraded by certain
western technology and materials including shaker screens, monitoring equipment
and drilling and completion fluids. Such measures, along with paying for Russian
equipment and personnel in rubles, allows GEOILBENT to minimize its investment
and operating expenses.

         Russia has established an export tariff on all oil exported from Russia
which, as imposed, has the effect of significantly reducing the cash flows and
potential profits to the Company. However, Russia has 


                                       7
<PAGE>   21

issued or drafted various decrees and legislation under which certain oil and
gas joint ventures, including GEOILBENT, are eligible for relief from such oil
export tariff until such time as they have recovered their capital investment.
GEOILBENT has received a waiver from the export tariff for 1995, and expects to
apply for renewal of such waiver for 1996 and 1997. However, there can be no
assurance that any such renewals can be obtained. Furthermore, after the waiver
for 1995 was issued to GEOILBENT, a new Russian law came into force which
repeals all tax and customs benefits previously granted to participants in
foreign economic activities, except for those granted pursuant to certain
federal laws, including the law "On Customs Tariff". While it is not clear
whether the repeal applies to GEOILBENT'S waiver for 1995, GEOILBENT believes
that its waiver should be regarded as granted pursuant to the law "On Customs
Tariff". The legislative and regulatory environment in Russia continues to be
subject to frequent change and uncertainty. The Company believes that the joint
venture partners will continually assess regulatory and economic conditions
affecting the Russian operations, make investment decisions accordingly and make
adjustments to the amount and/or timing of contribution requirements as
appropriate and permitted under the law. In addition, the license which grants
GEOILBENT the right to develop the North Gubkinskoye Field sets forth required
levels of oil and gas production through the year 2000 and requires GEOILBENT to
make additional royalty payments in the event that such production levels are
not achieved during any three year period.

         As part of its plan to fund the development of the North Gubkinskoye
Field, the Company has retained Morgan Guaranty to act as financial advisor to
the Company and GEOILBENT in obtaining project debt financing. Morgan Guaranty
has assisted the Company in approaching multilateral financial institutions and
export finance agencies. Any retainer and percentage success fees paid to Morgan
Guaranty will be credited as the Company's capital contribution. There can be no
assurance that such financing will become available on terms acceptable to the
Company or GEOILBENT.

         GEOILBENT has been successful, on a limited basis, in obtaining working
capital funding from certain institutions in Moscow. NAFTA Moscow, the exporter
which handles GEOILBENT's oil sales, made a short-term production payment
advance during the quarter ended March 31, 1995 of $3.0 million. International
Moscow Bank, which is majority owned by non-Russian European banks, has made two
short-term loans to GEOILBENT totaling $7 million. The bank loans were
guaranteed by the Company, which is providing certain portions of the cash for
such debt service during 1995 to complete its charter fund obligation.

will, by that tender, consent to the Proposal. If a Partnership adopts the
Proposal by the consent of 75% of the Partnership Units, all Investors in that
Partnership, whether or not they tendered their Units in the Exchange Offer,
will receive the same amount of Common Stock and Warrants they would have
received had they tendered their Partnership Units. CONSUMMATION OF THE EXCHANGE
OFFER FOR A PARTNERSHIP IS CONDITIONED UPON APPROVAL BY THAT PARTNERSHIP OF THE
PROPOSAL. APPROVAL OF THE PROPOSAL AND ADOPTION OF THE EXCHANGE OFFER IS NOT
CONDITIONED UPON APPROVAL AND ACCEPTANCE BY ANY OTHER PARTNERSHIP. See "The
Exchange Offer and Proposal." Holders of Units in the Partnerships who elect to
accept the Exchange Offer may choose to accept cash in lieu of the Common Stock
to be issued, BUT CASH WILL BE 


                                       9
<PAGE>   23

DISTRIBUTED TO THE HOLDER ONLY IF THE SALE OF THE UMBRELLA POINT FIELD TO
GOLDKING TRINITY BAY CORP. ("GOLDKING"), AS DESCRIBED HEREIN, IS ACTUALLY
CONSUMMATED. A holder should make a decision to accept the Exchange Offer based
solely upon an investment decision in the Common Stock, because there can be no
assurance from Benton that the Goldking sale will be consummated. See "The
Exchange Offer and Proposal--Election to Receive Cash in Lieu of Common Stock"
and "Consent Procedures--Solicitation of Letters of Transmittal."

         Common Stock issued in the Exchange will be freely transferable
immediately following issuance. There will be no market for the Warrants. The
Exchange Offer may be withdrawn if Benton determines, in its sole discretion,
that a material change affecting the Partnerships has occurred. See "The
Exchange Offer and Proposal."

         1989-1 Partnership. Each holder of a 1989-1 Unit who tenders his Units
in connection with the Exchange Offer will receive 104 shares of Common Stock,
$.01 par value per share, of Benton (the "Common Stock"). No Warrants will be
issued in exchange for 1989-1 Units. Fractional shares of Common Stock will not
be issued in connection with the Exchange Offer or liquidation of the 1989-1
Partnership. A Partner in the 1989-1 Partnership otherwise entitled to a
fractional share of Common Stock will be paid in cash in lieu of such fractional
shares.

         In connection with the Exchange Offer, Benton is submitting a Proposal
to Investors in the 1989-1 Partnership to amend the 1989-1 Partnership Agreement
to provide for the transfer of all of the assets and liabilities of the 1989-1
Partnership to Benton as of the December 31, 1994 Effective Date in exchange for
Common Stock in the amount set forth above and the pro rata distribution of such
consideration in liquidation of the 1989-1 Partnership. EACH INVESTOR WHO
TENDERS HIS 1989-1 UNITS PURSUANT TO THE EXCHANGE OFFER WILL, BY THAT TENDER,
CONSENT TO THE 1989-1 PROPOSAL. If the 1989-1 Partnership adopts the Proposal by
the consent of 75% of the 1989-1 Units, all Investors in the 1989-1 Partnership,
whether or not they tendered their 1989-1 Units in the Exchange Offer, will
receive the same amount of Common Stock they would have received had they
tendered their 1989-1 Units. CONSUMMATION OF THE EXCHANGE OFFER FOR INVESTORS
WHO HAVE TENDERED THEIR 1989-1 UNITS IS CONDITIONED UPON APPROVAL OF THE 1989-1
PROPOSAL. APPROVAL OF THE 1989-1 PROPOSAL AND ADOPTION OF THE EXCHANGE OFFER IS
NOT CONDITIONED UPON APPROVAL AND ACCEPTANCE BY ANY OTHER PARTNERSHIP. See "The

Stock, and (ii) Warrants to purchase 249 shares of Common Stock with an exercise
price of $12.37 per share. Fractional shares of Common Stock will not be issued
in connection with the Exchange Offer or liquidation of the 1990-1 Partnership.
A Partner in the 1990-1 Partnership otherwise entitled to a fractional share of
Common Stock will be paid in cash in lieu of such fractional shares. Warrants to
be issued will be rounded to the nearest whole number of Warrants and no
fractional interests will be issued.

in connection with the Exchange Offer or liquidation of the 1991-1 Partnership.
A Partner in the 1991-1 Partnership otherwise entitled to a fractional share of
Common Stock will be paid in cash in lieu of such fractional shares. Warrants to
be issued will be rounded to the nearest whole number of Warrants and no
fractional interests will be issued.

         In connection with the Exchange Offer, Benton is submitting a Proposal
to Investors in the 1991-1 Partnership to amend the 1991-1 Partnership Agreement

                    RISK FACTORS AND MATERIAL CONSIDERATIONS

         The Exchange Offer. In addition to the information included in this
Prospectus, the Investors should carefully consider the following factors in
determining whether to accept the Exchange Offer and consent to the Proposal.
The risks and effects of the Exchange will not be different for investors based
solely upon the Partnership in which he has invested. The risk factors
summarized below are described in further detail elsewhere in this Prospectus at
"Risk Factors and Material Considerations," beginning at page 34.

         Lack of Arm's Length Negotiations and Uncertainties in the Method of
         Determining Exchange Values. The Exchange Values were determined by
         Benton, based in part on an offer for the purchase of substantially all
         of the assets of the Partnerships from an unaffiliated third party, but
         may not reflect the actual value of the net assets of the respective
         Partnerships. The primary assets of each of the Partnerships considered
         by Benton when determining the Exchange Value were the proved oil and
         gas reserves of that Partnership (the "Proved Reserves") and the
         present value of associated future net cash flow as of December 31,
         1994, as well as the offer to purchase the Umbrella Point Field,
         described herein. There are many uncertainties inherent in estimating
         quantities of Proved Reserves, and the present value attributed to each
         Partnership's Proved Reserves may be less than the discounted future
         net cash flows actually received from that Partnership's interest in
         its wells. In that event, the use of this valuation methodology will
         have 


                                       11
<PAGE>   25

         resulted in an undervaluation of the Partnership Units. See "Method of
         Determining Exchange Values."

         Potential Decline in Market Price of Common Stock. Access to an active
         trading market by exchanging Investors may result in a relatively large
         number of shares of Common Stock offered for sale immediately after the
         Closing Date. This may tend to lower the market price for the Common
         Stock. Future market conditions in the oil and gas industry in general
         or the effect of the conditions on Benton in particular could also
         adversely affect the market price of the Common Stock and thus the
         value of the Warrants. There can be no assurance regarding the
         potential appreciation in the market price of the Common Stock. Any
         decline in the market price of the Common Stock could reduce the
         Investor's return on investment or increase the loss on the Investor's
         original investment.

         Potential Benefits of Alternatives to the Exchange. The alternatives to
         the Exchange Offer are the continuation of the Partnerships or the
         liquidation of the Partnerships' assets and distribution of the
         liquidation proceeds to Investors, either of which could potentially be
         more beneficial to Investors than the Exchange by avoiding the risks
         associated with ownership of Benton Common Stock and, in the case of a
         liquidation of the Partnerships, by providing an immediate cash return
         to Investors. See " Reasons for the Exchange Offer --Recommendation of
         the Managing General Partner" and "--Alternatives to the Exchange."

         Lack of Independent Representatives for Investors; No Fairness Opinion.
         No independent representative was selected or hired to represent the
         interests of the Investors in negotiating the terms of the Exchange
         Offer. The Exchange Values and other terms of the Exchange Offer may
         therefore be inferior to those that could have been negotiated by an
         independent representative. Benton did not retain an independent third
         party to render an opinion regarding the fairness of the terms of the
         Exchange Offer to the Investors.

         Limited Dissenters' Rights or Appraisal Rights. Investors who are
         California residents and who oppose the Proposal will have limited
         dissenters' rights. Other Investors who oppose the Proposal will have
         no dissenters' rights or appraisal rights, and therefore, no option to
         receive cash based on a separate appraisal of the Partnership assets in
         lieu of the Common Stock and Warrants based on the Exchange Values
         determined by Benton. The Managing General Partner could have provided
         all Investors with appraisal rights in structuring the Exchange Offer
         but elected not to do so, primarily because such rights are not
         provided for in the Partnership Agreements. The absence of these rights
         limit the options that would otherwise be available to Investors
         opposing the Exchange Offer.

         Investors residing in California will be afforded limited dissenters'
         rights in accordance with the requirements for roll-up transactions
         under the California Code. By voting against the Proposal, Investors in
         the State of California will be deemed to exercise their dissenters'
         rights and will receive the number of shares of Common Stock and
         Warrants equal to the Exchange Value of their interests divided by the
         closing price of the Common Stock on the NASDAQ-NMS during the twenty
         days immediately after the Closing Date. If that average price is lower
         than the Exchange Price, dissenting California Investors will receive
         more shares of Common Stock than they would otherwise receive in the
         Exchange Offer. California Investors hold a substantial portion of the
         interests in the 1989-1 Partnership, the 1990-1 Partnership and the
         1991-1 Partnership, and the impact of the exercise of dissenters'
         rights could materially increase the number of shares of Common Stock
         issued by Benton in connection with the Exchange Offer.



                                       12

         Benton will furnish to any Investor, upon oral or written request, a
         current alphabetized listing of the names and addresses of all
         Investors of the Partnership in which the requesting Investor owns an
         interest. Requests should be addressed to Benton Oil and Gas Company,
         Investor Relations, 1145 Eugenia Place, Suite 200, Carpinteria,
         California 93013, telephone number (805) 566-5600. Investors also have
         the right under the Partnership Agreements to inspect the books and
         records of the Partnership.

         Conflicts of Interest of Benton. Benton is the Managing General Partner
         of each of the Partnerships and its determination of the Exchange
         Values involves an inherent conflict of interest. As Managing General
         Partner, Benton owes fiduciary duties to the Investors in the
         Partnerships. In addition, it owes a duty to its stockholders. While
         Benton believes that it has fulfilled these obligations in its
         determination of the Exchange Values, which is supported, in part, by a
         reserve report audited by an independent petroleum engineer, no degree
         of objectivity or professional competence can eliminate the inherent
         conflict of interest. See "Reasons for the Exchange Offer--Fiduciary
         Duties of Benton."

         Benton Dividend Policy. Benton's policy is to retain its earnings to
         support the growth of Benton's business. Accordingly, the Board of
         Directors of Benton has never declared cash dividends on its Common
         Stock and does not plan to do so in the foreseeable future.
         Furthermore, the terms of Benton's debt agreements prohibit Benton from
         paying cash dividends on its Common Stock. Thus, upon consummation of
         the Exchange, Investors will no longer receive cash distributions and
         it is unlikely that cash dividends will be paid on the Benton Common
         Stock at any time in the foreseeable future.

         No Fractional Shares. No fractional shares will be issued in connection
         with the Exchange Offer. An Investor who would otherwise be entitled to
         a fractional share of Common Stock will be paid cash in lieu of such
         fractional shares. Warrants issued in connection with the Exchange
         Offer will be rounded to the nearest whole number of Warrants and no
         fractional interest will be issued.

         Risks Associated with Ownership of Common Stock of Benton. In addition
to the information included in this Prospectus, the Investors should carefully
consider the following factors related to Benton in determining whether to
accept the Exchange Offer. The risk factors summarized below are described in
further detail elsewhere in this Prospectus at "Risk Factors and Material
Considerations."

         Losses From Benton's Operations. The historical financial data for
         Benton reflects net losses and decreased revenues for the years ended
         December 31, 1992 and 1993. Benton's ability to maintain its financing
         arrangements, produce its oil and gas reserves and service its debt
         obligations would be adversely affected by a lack of profitability.

         Foreign Operations. Almost all of Benton's oil and gas revenues and
         Proved Reserves are attributable to its operations in Venezuela and
         Russia. Benton's Venezuelan and Russian operations are subject to
         political, economic and other uncertainties inherent in the development
         of foreign properties.

         Properties Under Development. A substantial amount of Benton's Proved
         Reserves are undeveloped and require development activities and/or are
         proved developed behind-pipe or shut-in and require additional
         development activities. As a result, Benton will require substantial
         capital expenditures to develop all of its Proved Reserves.



                                       13
<PAGE>   27

         Engineers' Estimates of Reserves and Future Net Revenue. This
         Prospectus contains, and incorporates by reference, estimates of
         Benton's and the Partnerships' oil and gas reserves and future net
         revenues therefrom. Estimates of commercially recoverable oil and gas
         and the future net cash flows derived therefrom are based upon a number
         of variable factors and assumptions. Estimates to some degree are
         speculative and estimates of the commercially recoverable reserves of
         oil and natural gas, and the future net cash flows therefrom, prepared
         by different engineers or by the same engineer at different times, may
         vary substantially. The difficulty of making precise estimates is
         accentuated because most of Benton's Proved Reserves were non-producing
         at December 31, 1994.

         Development of Additional Reserves. Benton's future success may also
         depend upon its ability to find or acquire additional oil and gas
         reserves that are economically recoverable. There can be no assurance
         that Benton will be able to discover additional commercial quantities
         of oil and gas, or that Benton will be able to continue to acquire
         interests in underdeveloped oil and gas fields and enhance production
         and reserves therefrom.

         Partnership Litigation. Certain limited partners in Benton's oil and
         gas limited partnerships, including the Partnerships that are the
         subject of this Exchange Offer, filed suit against Benton and others
         alleging breaches of contract, fiduciary duty and fraud. This suit has
         been voluntarily dismissed, subject to an agreement among the parties
         to arbitrate the issues and claims which were the subject of the claim.
         See "The Exchange Offer and Proposal--Litigation and Related Matters."

         In addition, investors in partnerships which were sponsored by a third
         party have sued Benton on the theory that since it provided oil and gas
         drilling prospects to those partnerships and operated substantially all
         of their properties, it was responsible for alleged violations of
         securities laws in connection with the offer and sale of interests,
         contractual breach of fiduciary duty and fraud. See "The Exchange Offer
         and Proposal--Litigation and Related Matters."

         Retention and Attraction of Key Personnel. Benton 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 Benton's business.

         Regulation. The oil and gas industry is subject to broad and frequently
         changing regulations that could adversely affect the operations of
         Benton.

         In spite of the foregoing risks, Benton initiated and proposed the
Exchange Offer and recommends adoption of the Proposals by each of the
Partnerships to enable Benton to acquire the assets and liabilities of each of
the Partnerships and to provide Investors with the potential benefits summarized
below under the caption "Reasons for the Exchange Offer."

                   BACKGROUND AND ALTERNATIVES TO THE EXCHANGE

         Background. Each of the Partnerships has completed its respective
drilling operations and acquisitions. Benton has received inquiries and concerns
from Investors and determined that the Partnerships had each reached the stage
in its production history where consideration of the Exchange Offer became
appropriate. That determination was based on the following factors:


                                       14
<PAGE>   28

   *     Production Declines. Since 1993, the Partnerships' oil production
         volumes have declined from peak levels reached in 1992. Gas production
         began to decline in 1993 and 1994. These reductions are due to the
         natural decline occurring in the Umbrella Point Field, the
         Partnerships' most significant asset. Production volumes are expected
         to decline further in subsequent periods due to ongoing depletion of
         the Partnerships' wells. The decline in production rates due to
         depletion of reserves is neither unusual nor unexpected in the oil and
         gas industry.

   *     Declining Distribution Rates. The Partnerships' production declines
         commencing in 1993 and 1994 contributed to the Partnerships' declining
         distribution rates in 1993 and 1994.

   *     Partnership Litigation. Litigation, in the form of arbitration, has
         been instituted against Benton by certain investors in the Partnerships
         which are the subject of this Exchange Offer. The claims made by the
         investors have not been clearly defined. However, in general terms, the
         investors allege that the Company failed to comply with the
         requirements of the Partnership Agreements with respect to the reports
         to be sent to individual partners, including audited financial
         statements and reserve reports, commingling of funds, breach of its
         fiduciary duties, fraudulent inducement to invest, conversion and
         negligent representation. The Company intends to vigorously defend its
         actions related to these Partnerships. However, the Company does
         believe that it is in its best interest and the best interests of the
         partners to resolve these issues, as it relates to the Partnerships,
         and to terminate the Partnerships on the terms set forth herein. The
         Company anticipates that if the Exchange Offer is approved, this will
         lessen the chance of additional litigation with respect to the
         Partnerships and may limit the potential damages with respect to the
         existing arbitration.

   *     Benton's Acquisition of the Partnership Properties. Although Benton has
         executed agreements for the sale of each of the Partnership's
         respective interests in the Umbrella Point Field, which constitutes
         substantially all of the assets of the Partnerships, there can be no
         assurance that the contemplated sale will be consummated. Benton has
         made the Exchange Offer to acquire the assets of these Partnerships
         approving the Proposals, and then intends to sell the Umbrella Point
         Field to Goldking on the terms described herein. Benton is a natural
         acquisition candidate for various reasons, including Benton's (i)
         interest in reducing the overhead involved in administration of the
         Partnerships as Managing General Partner, (ii) greater diversification
         and capital resources enabling Benton to fund liabilities and expenses
         necessary for the full development of the Partnerships' properties
         (iii) interest in responding to the Investor's concerns about the
         future prospects of the Partnerships, since many of the Investors are
         also stockholders of Benton, and (iv) ability to assume the risk that
         the sale to Goldking will not be consummated. Although the acquisition
         of the Partnership's assets pursuant to the Exchange Offer will result
         in a charge against Benton's income, Benton does not expect that this
         one time charge will have a significant adverse affect on the market
         value of the Benton Common Stock.

Alternatives to the Exchange. Although Benton has considered the continuation of
the Partnerships or liquidation of the Partnerships as potential alternatives to
the Exchange Offer, these alternatives were rejected for various reasons,
including the following:

   *     Solicitation of Offers to Purchase Partnership Properties. Benton has
         solicited bidders for the assets of each of the Partnerships. The
         interest in purchasing the assets of the Partnerships was limited. As
         discussed herein, Benton has received an offer to purchase the working
         interest of each of the Partnerships in the Umbrella Point Field from
         Goldking, for cash. The estimated cash proceeds to the 1989-1
         Partnership, the 1990-1 Partnership and the 1991-1 Partnership are
         $375,643, 



                                       15
<PAGE>   29

         $1,081,589 and $215,280, respectively, as of March 31, 1995 subject to
         adjustments. In addition to the Goldking offer, Benton had received an
         offer to purchase the working interests in the Umbrella Point Field
         from Hunter Resources, Inc. ("Hunter") in October 1994. Pursuant to the
         terms of that offer, Hunter would have paid a total of $8,000,000 in
         cash and $1,000,000 in the form of a promissory note. Pursuant to this
         offer, the 1989-1 Partnership, the 1990-1 Partnership and the 1991-1
         Partnership would have received aggregate cash consideration in the
         amount of $394,313, $1,135,346 and $225,980, respectively, and a
         promissory note in the aggregate amount of $49,289, $141,918 and
         $28,248, respectively. The offer was subsequently withdrawn due to
         Hunter's inability to secure financing for the transaction. Although
         several other companies reviewed reserve information, production
         records and well data, no other serious inquiries were received by
         Benton for the purchase of the Partnerships' assets and Benton believes
         that no offer to purchase the assets of the Partnerships will be in
         excess of the Total Exchange Values.

   *     Lack of Partnership Resources and Declining Reserves. Continuation of
         the Partnerships, while avoiding the risks associated with the Exchange
         Offer and the discontinuance of cash distributions, would result in
         declining operating results and distribution rates for each of the
         Partnerships because: (i) reserves will be depleted in the ordinary
         course from ongoing production, (ii) General and administrative
         expenses will remain the same regardless of the operating results of
         the Partnership assets, and (iii) the Partnership would have to incur
         the cost of plugging and abandoning Partnership wells when they become
         uneconomic or any future sale of the Partnership's wells would be at a
         price which would reflect the anticipated costs of such plugging and
         abandonment expenses.

   *     Management's Conclusions Regarding Likelihood of Unaffiliated Bidders
         at Comparable Values. Benton has solicited bidders for the assets of
         the Partnerships, and none of the bids were in excess of the
         liquidation values of the Partnerships. Benton has concluded that,
         while an asset sale in liquidation might generate limited third party
         interest, a sale of the assets of the Partnerships would not provide
         immediate cash returns to Investors in excess of the liquidation value
         of the Partnerships and would likely result in valuations by a third
         party bidder below the Total Exchange Values of the Partnership Units.
         Benton has undertaken an analysis of the current liquidation value of
         each of the Partnerships. Results of that liquidation analysis reflect
         liquidation values for the 1989-1 Partnership, the 1990-1 Partnership
         and the 1991-1 Partnership estimated at $1,152, $807 and $946,
         respectively, or approximately 11%, 55% and 55%, respectively, less
         than the Total Exchange Values. In view of the uncertainties inherent
         in the Managing General Partner's analysis and the lack of an
         independent appraisal of the value, however, there can be no assurance
         that obtaining additional bids for arm's length sales of assets of the
         Partnerships would not result in valuations that would be comparable to
         or higher than the Total Exchange Values, while also avoiding the risks
         associated with ownership of the Common Stock.

         REASONS FOR THE EXCHANGE OFFER; RECOMMENDATION OF THE MANAGING 
GENERAL PARTNER

         1989-1 Partnership. The Managing General Partner believes that the
Exchange Offer is fair to and in the best interests of the 1989-1 Partnership
and its Investors, and recommends that the Investors in the 1989-1 Partnership
consent to the Proposal and accept the Exchange Offer. See "Background of
Exchange Offer." The recommendation is based on a number of factors discussed in
this Prospectus. See "Reasons for the Exchange Offer--Recommendation of the
Managing General Partner." If the Exchange is not consummated, the 1989-1
Partnership will continue to operate its properties and the Managing General
Partner will review alternatives that may come available from time to time.

         1990-1 Partnership. The Managing General Partner believes that the
Exchange is fair to and in the best interests of the 1990-1 Partnership and its
Investors, and recommends that the Investors in the 1990-1 Partnership consent
to the Proposal and accept the Exchange Offer. See "Background of Exchange
Offer." The recommendation is based on a number of factors discussed in this
Prospectus. See "Reasons for the Exchange Offer--Recommendation of the Managing
General Partner." If the Exchange is not consummated, the 1990-1 Partnership
will continue to operate its properties and the Managing General Partner will
review alternatives that may come available from time to time.

         1991-1 Partnership. The Managing General Partner believes that the
Exchange Offer is fair to and in the best interests of the 1991-1 Partnership
and its Investors, and recommends that the Investors in the 1991-1 Partnership
consent to the Proposal and accept the Exchange Offer. See "Background to
Exchange Offer." The recommendation is based on a number of factors discussed in
this Prospectus. See "Reasons for the Exchange Offer--Recommendation of the
Managing General Partner." If the Exchange is not consummated, the 1991-1
Partnership will continue to operate its properties and the Managing General
Partner will review alternatives that may come available from time to time.

                           SUMMARY OF TAX CONSEQUENCES

         Upon consummation of the Exchange, Investors will realize gain in an
amount equal to the excess of the fair market value of the Common Stock and
Warrants received by them over their respective bases in the Partnership Units
they hold.

         Assuming the Investor has held his Interest for more than one year and
assuming his Units have not been held for sale in the ordinary course of the
Investor's trade or business, any gain or loss realized upon the transfer of the
Partnership Units will be taxed as long term capital gain or loss, except to the
extent that the consideration received is attributable to his allocable share of
substantially appreciated inventory items and unrealized receivables (including
depreciation recapture and excess intangible drilling and development costs) of
the Partnerships. The portion of any gain attributable to these items will be
taxed to the Investor as ordinary income.

         Investors should read the more detailed discussion of the federal
income tax consequences contained in "Certain Federal Tax Consequences" and are
also urged to consult with their own tax advisors with respect to the tax
consequences to them of the transaction, including the application of state,
local and foreign tax laws.

                              ACCOUNTING TREATMENT

         The Exchange will be accounted for as a purchase by Benton.
Accordingly, the purchase price will be allocated to assets and liabilities
based on their estimated values as of the date of acquisition.

 BUSINESS OF BENTON AND THE PARTNERSHIPS AFTER THE CONSUMMATION OF THE EXCHANGE

         Benton is an independent oil and gas company engaged in the acquisition
of producing properties and the exploration, development and production of oil
and gas, primarily in the eastern region of Venezuela, the Gulf Coast of
Louisiana and the West Siberia region of Russia. Upon consummation of the
Exchange Transactions, Benton will operate the acquired Partnership assets as it
operates its oil and gas properties or may sell such assets to third parties at
any time. See "Background of Exchange Offer--Goldking Offer."

                     COMPARATIVE RIGHTS OF SECURITY HOLDERS

         For a comparison of the rights of Benton stockholders under Delaware
law and Benton's Certificate of Incorporation and Bylaws with the rights of the
Partners of each of the Partnerships under California law and the respective
Partnership Agreements, see "Comparative Rights of Security Holders."

                               DISSENTERS' RIGHTS

         Investors residing in states other than California will not be afforded
any dissenters' or appraisal rights. Under the rules adopted by the National
Association of Securities Dealers, Inc. ("NASD"), investors in roll-up
transactions such as the Exchange Offer are entitled to certain dissenters'
rights unless the sponsor adopts a 75% approval requirement for the transaction
or other procedures designed to protect the rights of investors. Although
adoption of the Proposals by each of the Partnerships would require the consent
under the Partnership Agreements of the holders of only a majority of the
Partnership Units, the Managing General Partner has adopted a 75% approval
procedure instead of providing dissenters' rights.

         Investors residing in California will be afforded limited dissenters'
rights in accordance with the requirements for roll-up transactions under the
California Code. By voting against the Proposal, Investors in the State of
California will be deemed to exercise their dissenters' rights and will receive
the number of shares of Common Stock and Warrants equal to the Exchange Value of
their interests divided by the closing price of the Common Stock on the
NASDAQ-NMS during the twenty days immediately after the Closing Date. If that
average price is lower than the Exchange Price, dissenting California Investors
will receive more shares of Common Stock than they would otherwise receive in
the Exchange Offer. California Investors hold a substantial portion of the
interests in the 1989-1 Partnership, the 1990-1 Partnership and the 1991-1
Partnership and the impact of the exercise of dissenters' rights could
materially increase the number of shares of Common Stock issued by Benton in
connection with the Exchange Offer.

         Benton will furnish to any Investor, upon oral or written request, a
current alphabetized listing of the names and addresses of all Investors of the
Partnership in which the requesting Investor owns an interest. Requests should
be addressed to Benton Oil and Gas Company, Investor Relations, 1145 Eugenia
Place, Suite 200, Carpinteria, California 93013, telephone number (805)
566-5600. Investors also have the right under the Partnership Agreements to
inspect the books and records of the Partnership.

                         RESALES OF BENTON COMMON STOCK

         The shares of Common Stock that will be issued to Investors in
connection with the Exchange and upon liquidation of the Partnerships have been
registered under the Securities Act. All shares of Common Stock received by
Investors will be freely tradable by those Investors.

                           DESCRIPTION OF THE WARRANTS

         To holders of 1990-1 Units and 1991-1 Units who accept the Exchange
Offer, Benton will issue Warrants to purchase shares of Common Stock. Each
Warrant issued pursuant to the Exchange Offer will entitle the holder to
purchase one share of Common Stock for each Warrant held, at an exercise price
of $12.37 per share, subject to adjustment in certain circumstances. The
Warrants will be issued pursuant to a Warrant Agreement, the form of which is
attached hereto as Exhibit A. Pursuant to the terms of the 


                                       18
<PAGE>   32

Warrant Agreement, the Warrants will expire three years from the date issuance.
The number of shares of Common Stock and the exercise price of the Warrants is
subject to adjustment under certain circumstances, as described therein,
including issuance of Common Stock or securities convertible into Common Stock
to all holders of Benton Common Stock, exchange of Common Stock of Benton for
other securities, issuance of Common Stock or other securities to all holders
upon merger, reorganization, or sale of assets. The Warrants are not subject to
redemption or call by Benton. If the Exchange Offer is accepted by more than 75%
of the holders of the 1990-1 Units and the 1991-1 Units, Benton will issue to
all holders of such Units, Warrants to purchase an aggregate of 432,850 shares
of Common Stock. On July 17, 1995, there were Warrants to purchase an aggregate
of 1,919,752 shares of Common Stock issued and outstanding. See "Description of
Securities."

         The number of Warrants to be issued in exchange for 1990-1 Units and
1991-1 Units has been determined by dividing the estimated value of the General
Intangibles of the Partnership by the estimated present value of $3.38 per
Warrant. Benton has used the Black-Scholes option pricing model to calculate the
present value of the Warrants. THE ACTUAL VALUE, IF ANY, A HOLDER MAY REALIZE
FROM THE WARRANTS WILL DEPEND ON THE EXCESS OF THE MARKET PRICE OF THE COMMON
STOCK OVER THE EXERCISE PRICE OF THE WARRANT ON THE DATE THE WARRANT IS
EXERCISED, SO THAT THERE IS NO ASSURANCE THE VALUE REALIZED BY A HOLDER WILL BE
AT OR NEAR THE VALUE ESTIMATED BY THE BLACK-SCHOLES OPTION PRICING MODEL. The
estimated values under the model for the Warrants are based on assumptions that
include (i) a stock price volatility of 30%, (ii) a risk-free rate of return
based on a three-year swap curve rate of 5.88%, and (iii) a Warrant exercise
term of three years. The Securities and Exchange Commission requires disclosure
of the value of consideration offered in connection with the Exchange Offer.
BENTON'S USE OF THE BLACK-SCHOLES MODEL TO INDICATE THE PRESENT VALUE OF THE
WARRANTS TO BE ISSUED IS NOT AN ENDORSEMENT OF THIS VALUATION, WHICH IS BASED
UPON CERTAIN ASSUMPTIONS, INCLUDING THE ASSUMPTION THAT THE WARRANT WILL BE HELD
FOR THE FULL THREE-YEAR TERM PRIOR TO EXERCISE.

       MATERIAL ADVANTAGES AND DISADVANTAGES OF THE EXCHANGE AND PROPOSALS

         In considering the Exchange, the Managing General Partner took into
account various advantages and disadvantages of the Exchange to each of the
Partnerships and its respective Investors. The advantages the Managing General
Partner considered included:

         (a) the total consideration to be received by each of the Partnerships
represents a premium over the standardized measure of discounted net cash flows
relating to each of the Partnerships Proved Reserves at December 31, 1994 plus
working capital;

         (b)  Benton's historical financial results and future prospects;

         (c) the consideration to be received by each of the Partnerships in
connection with the Exchange represents consideration to the Investors in excess
of that which could be expected from continued cash distributions;

         (d) the Investors will receive the benefit of any future growth in the
value of their equity interest in Benton rather than receiving cash
distributions from the Partnerships, which are likely to decrease rapidly as the
remaining oil and natural gas reserves of the Partnerships are depleted;

         (e) liquidity of the Common Stock of Benton compared to the lack of
liquidity of the Partnership Units; and


                                       19
<PAGE>   33

         (f) the ability of the investors to choose to receive cash in lieu of
Common Stock of Benton, if the sale of Umbrella Point Field to Goldking is
consummated.

         The Managing General Partner also considered certain disadvantages that
included:

         (a) the possibility that the price of oil and gas could increase,
thereby increasing the value of the assets of the Partnerships, which could have
a more direct effect to the Investors if owned by the Partnerships rather than
Benton;

         (b) Benton is restricted under certain credit agreements from paying
cash dividends to its stockholders and the Investors could continue to receive
cash distributions from the Partnerships;

         (c) tax consequences to the Investors in connection with the Exchange
and liquidation of the Partnerships;

         (d) the possibility that the reserve estimates for the Partnerships
could be undervalued; and

         (e)  risks associated with the market value of Benton Common Stock.

         See "Reasons for the Exchange Offer." For other relevant factors, see
also "Risk Factors and Material Considerations."

             OFFER TO PURCHASE INTERESTS IN THE UMBRELLA POINT FIELD

         In June 1995, Benton received an offer from Goldking Trinity Bay Corp.
("Goldking") to purchase all of the right, title and interest owned by each of
the Partnerships and Benton in the Umbrella Point Field. The financing of the
Goldking acquisition was subject to the ability of Goldking to acquire at least
75% of the working interests in the Field, and therefore, to preserve the offer
for the Partnerships, Benton sold its corporate interest in the Umbrella Point
Field (11.77% working interest) to Goldking for $756,872. Benton entered into
agreements, on behalf of each of the Partnerships, with Goldking for the sale of
the Partnerships' interests in the Umbrella Point Field, subject to approval of
the Partnerships. In consideration of the sale, the 1989-1 Partnership, the
1990-1 Partnership and the 1991-1 Partnership would receive anticipated net
proceeds in the aggregate of $375,643, $1,081,589 and $215,280, respectively, if
the sale were consummated as of March 31, 1995.

           METHOD OF DETERMINING EXCHANGE VALUE FOR 1989-1 PARTNERSHIP

         Components of the Exchange Value. The most significant assets
considered by Benton in determining the Exchange Value of the 1989-1 Units were
the anticipated net proceeds from the sale of the Umbrella Point Field. The
Exchange Values represent the sum of (i) the estimated cash proceeds from the
anticipated sale to Goldking of the Umbrella Point Field, and (ii) the tax-basis
balances of equipment as of December 31, 1994 and the net book value of current
assets and liabilities (reflected on the unaudited balance sheet) of the 1989-1
Partnership as of March 31, 1995. These components represent all of the assets
and liabilities of the 1989-1 Partnership and were determined as of March 31,
1995 to conform with the SEC reporting requirements for unaudited financial
information.

         The following unaudited table sets forth (i) the components of the
Exchange Values of the 1989-1 Units and (ii) the Exchange Value per 1989-1 Unit
held by an Investor. This information was compiled by Benton from the 1989-1
Partnership's tax records for the year ended December 31, 1994 and financial
statements for the three months ended March 31, 1995.

         Anticipated Sales Proceeds. In July 1995, Benton, on behalf of the
1989-1 Partnership, and Goldking executed an agreement whereby Goldking will
purchase a 4.93% working interest in the Umbrella Point Field from the 1989-1
Partnership, subject to approval of the participants of the Partnership. Upon
execution of the agreement, Goldking made an earnest money deposit in favor of
the Partnership. Subject to closing adjustments, as of March 31, 1995 the
Partnership's estimated cash proceeds from the sale would be $375,643, or $1,333
per 1989-1 Unit. Benton has made this Exchange Offer in contemplation of such
sale, but the Exchange Offer is not conditioned upon consummation of such sale.

           METHOD OF DETERMINING EXCHANGE VALUE FOR 1990-1 PARTNERSHIP

         Components of the Exchange Value. The most significant assets
considered by Benton in determining the Exchange Value of the 1990-1 Units were
the anticipated net proceeds from the sale of the Umbrella Point Field and
Proved Reserves of the 1990-1 Partnership. The Exchange Values represent the sum
of (i) the estimated cash proceeds from the anticipated sale of Umbrella Point
Field to Goldking, (ii) the estimated present value of future net cash flows
from the Proved Reserves of the 1990-1 Partnership as of December 31, 1994,
discounted at 10% per year and calculated without escalation of prices and
costs, as reflected in the reserve report for the 1990-1 Partnership as of that
date prepared by Benton and audited by Huddleston & Co., Inc., independent
petroleum engineers ("Huddleston"), (iii) the tax-basis balances of equipment as
of December 31, 1994 and the net book value of current assets and liabilities
(reflected on the unaudited balance sheet) of the 1990-1 Partnership as of March
31, 1995, and (iv) the value of General Intangibles. These components represent
all of the assets and liabilities of the 1990-1 Partnership and were determined
as of the year end and March 31, 1995 to conform with the SEC reporting
requirements for reserve information and unaudited financial information,
respectively. Since the year-end reserve information is audited, the Exchange
Values were derived from that information.

         The following unaudited table sets forth (i) the components of the
Exchange Values of the 1990-1 Units and (ii) the Exchange Value per 1990-1 Unit
held by an Investor. This information was compiled by Benton from the 1990-1
Partnership's reserve report as of December 31, 1994 (a summary of which is
included in Exhibit B to this Prospectus) and the 1990-1 Partnership's tax
records for the year ended December 31, 1994 and financial statements for the
three months ended March 31, 1995.

(1)      No exchange value is attributable to Managing General Partner's
         interest.
(2)      Obtained by dividing the Total Exchange Value by 1,419.129 partnership
         units.
(3)      Value of estimated future net cash flows from Proved Reserves of the
         Partnership excluding the Umbrella Point Field, as of December 31,
         1994, as reflected in the reserve report for the Partnership as of that
         date.
(4)      Net book value of current assets and liabilities at March 31, 1995.
(5)      Tax-basis balances of equipment, excluding Umbrella Point Field
         equipment, at December 31, 1994.
(6)      Obtained by dividing the Exchange Value attributable to stock by the
         Common Stock price of $12.37, subject to rounding adjustments.
(7)      Obtained by dividing the estimated value of General Intangibles by the
         estimated present value of the Warrants ($3.38 per Warrant). Benton has
         determined the value attributed to General Intangibles based solely
         upon its evaluation of the success to date of the Partnership, total
         consideration paid to date to the participants and the value to Benton
         in dissolving and liquidating the Partnership.

         Anticipated Sales Proceeds. In July 1995, Benton, on behalf of the
1990-1 Partnership, and Goldking executed an agreement whereby Goldking will
purchase a 14.19% working interest in the Umbrella Point Field from the 1990-1
Partnership, subject to approval of the participants of the Partnership. Upon
execution of the agreement, Goldking made an earnest money deposit in favor of
the partnership. Subject to closing adjustments, as of March 31, 1995 the
Partnership's estimated cash proceeds from the sale would be $1,081,589, or $762
per 1990-1 Unit. Benton has made this Exchange Offer in contemplation of such
sale, but the Exchange Offer is not conditioned upon consummation of such sale.

         Proved Reserves. Proved Reserves of the 1990-1 Partnership and the
estimated net cash flows attributable thereto were derived from a reserve report
for the 1990-1 Partnership prepared by Benton and audited by Huddleston. The
reserve estimates were prepared in accordance with SEC regulations, with
estimated future net cash flows from Proved Reserves based on prices as of the
date of the report held constant over the estimated life of the reserves and
discounted at the prescribed rate of 10% per annum ("SEC PV 10"). No risk
adjustment factor was applied to the estimated future net cash flows from the
Proved Reserves of the 1990-1 Partnership to account for uncertainties inherent
in projecting future production rates, and no adjustment was made to take into
account fluctuations in oil and gas prices after December 31, 1994.

         General Intangibles. In determining the value attributed to General
Intangibles, Benton evaluated the success to date of the 1990-1 Partnership,
total consideration paid to date to the participants and the value to Benton of
dissolving and liquidating the 1990-1 Partnership so that Benton can focus on
its current operations and reduce the administrative burdens associated with
operating the Partnership.

From inception through July 1995, the 1990-1 Partnership has made cash
distributions to participants aggregating $2,452,364, or $1,728 per 1990-1 Unit.
Benton acknowledges the concerns raised by the Investors in the 1990-1
Partnership with regard to operations of the Partnership, the lack of success
and thus the disappointing returns on investment by the Investors. Because many
of the Investors are or were stockholders of Benton, Benton desires to maintain
a good relationship with these stockholders, many of whom have been strong
supporters of Benton from inception, and Benton desires to avoid future claims
against it by participants relating to the management of the Partnership. See
"The Exchange Offer and Proposal -- Litigation and Related Matters." Assuming
that the Investor in the 1990-1 Partnership elects to hold his or her shares of
Common Stock and exercises his or her Warrants at the end of the three-year
term, and the market price of the Common Stock is at or above approximately
$19.50 per share, Benton believes that the Investors in the 1990-1 Partnership
will have received consideration in the form of cash distributions, Common Stock
and Warrants in excess of the initial investment in the 1990-1 Partnership,
without regard to any tax benefits received by the participants. The value of
the General Intangibles of the Partnership is not subject to valuation by third
parties since the General Intangibles do not represent actual assets of the
Partnership. Benton believes that the participants in the Partnership will not
receive any value for the General Intangibles in any alternative to the
Exchange.

         Uncertainties Inherent in Valuation Methodology. There are numerous
uncertainties inherent in estimating quantities and production rates of
hydrocarbons. Estimates of the 1990-1 Partnership's Proved Reserves by
independent petroleum engineers other than Huddleston could result in higher or
lower valuations than those determined by Benton and audited by Huddleston. The
Exchange Values may not reflect the value of the 1990-1 Units or the value of
the properties attributable to the 1990-1 Units if sold to an unaffiliated third
party in an arm's length transaction.

           METHOD OF DETERMINING EXCHANGE VALUE FOR 1991-1 PARTNERSHIP

         Components of the Exchange Value. The most significant assets
considered by Benton in determining the Exchange Value of the 1991-1 Units were
the anticipated net proceeds from the sale of the Umbrella Point Field and
Proved Reserves of the 1991-1 Partnership. The Exchange Values represent the sum
of (i) the estimated cash proceeds from the anticipated sale of Umbrella Point
Field to Goldking, (ii) the estimated present value of future net cash flows
from the Proved Reserves of the 1991-1 Partnership as of December 31, 1994,
discounted at 10% per year and calculated without escalation of prices and
costs, as reflected in the reserve report for the 1991-1 Partnership as of that
date prepared by Benton and audited by Huddleston & Co., Inc., independent
petroleum engineers ("Huddleston"), (iii) the tax-basis balances of equipment as
of December 31, 1994 and the net book value of current assets and liabilities
(reflected on the unaudited balance sheet) of the 1991-1 Partnership as of March
31, 1995, and (iv) the value of General Intangibles. These components represent
all of the assets and liabilities of the 1991-1 Partnership and were determined
as of year end and March 31, 1995 to conform with the SEC reporting requirements
for reserve information and unaudited financial information, respectively. Since
the year-end reserve information is audited, the Exchange Values were derived
from that information.

         The following unaudited table sets forth (i) the components of the
Exchange Values of the 1991-1 Units and (ii) the Exchange Value per 1991-1 Unit
held by an Investor. This information was compiled by Benton from the 1991-1
Partnership's reserve report as of December 31, 1994 (a summary of which is
included in Exhibit B to this Prospectus) and the 1991-1 Partnership's tax
records for the year ended December 31, 1994 and financial statements for the
three months ended March 31, 1995.

                 CERTAIN HISTORICAL AND PRO FORMA FINANCIAL DATA

         Benton Selected Historical and Unaudited Pro Forma Consolidated
Financial Data. The following selected consolidated financial data for Benton
Oil and Gas Company as of and for each of the years in the five year period
ended December 31, 1994 are derived from Benton's audited consolidated financial
statements. The selected consolidated financial data for the three months ended
March 31, 1994 and 1995 are derived from Benton's unaudited financial
statements. In the opinion of management, such unaudited financial statements
contain all adjustments (consisting of only normal recurring accruals) necessary
for a fair presentation of the financial condition and results of operations as

(1)      The share information for the Company has been adjusted to reflect
         two-for-one stock splits in the form of 100% stock dividends effective
         July 9, 1990 and February 26, 1991.
(2)      The weighted average common shares outstanding for the Company have
         been adjusted for the effect of common stock equivalents for the years
         ended December 31, 1991 and 1990 and for the three months ended March
         31, 1995.
(3)      For the years ended December 31, 1991 and 1990 the Company recorded
         income tax expense of $174,000 and $41,000 respectively, and an
         extraordinary item for the utilization of loss carryforward for the
         same amounts.
(4)      No cash dividends were paid during any period presented.
(5)      For purposes of computing the ratio, "earnings" represents income
         (loss) from operations before income taxes and extraordinary items 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 losses incurred by the Company for the
         years ended December 31, 1993 and 1992 and the three months ended March
         31, 1994, earnings did not cover fixed charges by $4,829,000,
         $2,909,000 and $1,142,000, respectively.

                    RISK FACTORS AND MATERIAL CONSIDERATIONS

         In addition to the material contained elsewhere herein, the following
factors should be carefully considered.

RISKS RELATED TO THE EXCHANGE OFFER

         Elimination of Cash Distributions. The Exchange will result in the
Investors holding shares of Common Stock of Benton. Benton has paid no cash
dividends on its Common Stock and does not anticipate paying cash dividends on
its Common Stock in the foreseeable future. The cash distributions paid by the
1989-1 Partnership, the 1990-1 Partnership and the 1991-1 Partnership were $54,
$22 and $100 per $5,000 Unit, respectively, for each of the first three quarters
of 1994. Despite the elimination of cash distributions to the Partners in
connection with the Exchange, Benton believes that if the Partnerships were to
continue operations, the cash distributions that Investors would receive from
the Partnerships would rapidly decline as the reserves of the Partnerships are
depleted.

         Potential Decline in Market Price of the Common Stock. The Exchange
Values, together with the cumulative distributions paid by the Partnerships,
reflect a loss on an Investor's initial investment of $696, $1,473 and $1,701
per 1989-1 Unit, 1990-1 Unit and 1991-1 Unit, respectively. Investors will be
exposed to a greater loss on their investment if the market price for the Common
Stock declines below the Unit Exchange Price. The market price for the Common
Stock fluctuated during 1994 from a high of $9.125 per share to a low of $4.25
per share, with an average daily trading volume of 163,855 shares, and has
fluctuated from a high of $15.13 per share to a low of $8.63 per share during
1995. See "Price Range of Common Stock, Dividends and Distributions." There may
be a large number of shares of Common Stock offered for sale immediately after
the Closing Date for various reasons, including the liquidity that the Exchange
will afford to Investors, who have not had access to a trading market for the
Partnership Units and may wish to liquidate their investment at the first
opportunity. This may tend to lower the market price for the Common Stock. Any
return to depressed conditions in the oil and gas industry in general and the
effect of those conditions on Benton in particular could also adversely affect
the market price of the Common Stock. A downturn in the general economic and
stock market conditions or in the drilling record and production performance of
Benton or results of operations for Benton that are lower than expected by the
marketplace could be expected to have a similar impact on the Common Stock. The
number of shares of Common Stock offered in exchange for Partnership Units has
been determined by dividing the Exchange Value of the tangible assets of the
Partnerships by the Common Stock Exchange Price of $12.37, subject to rounding
adjustments. The Common Stock Exchange Price is based upon the closing price of
the Common Stock July 17, 1995, and will not be adjusted to reflect any
subsequent increase or decrease in the market price of the Common Stock after
that date, except to the extent required by dissenters' rights for California
residents. See "The Exchange Offer and Proposal--Dissenters' Rights."

         Lack of Arm's Length Negotiations to Determine Value of Partnership
Units. The Exchange Values of the Partnership Units ($1,292 for 1989-1 Units,
$1,799 for 1990-1 Units and $2,099 for 1991-1 Units) were determined by Benton
based, in part, on the estimated present value of each of the Partnerships'
Proved Reserves and Benton's valuation of the General Intangibles of each
Partnership (as described herein) and, as a result of Benton's inherent conflict
of interests and uncertainties involved in estimating reserve quantities and
values, may not reflect the value of the oil and gas properties and other assets
of each of the Partnerships if all such assets were sold to an unaffiliated
third party in an arm's length transaction. See "Uncertainties in the Method of
Determining Exchange Values" and "Valuation 


                                       34
<PAGE>   48

Conflict of Interest" below. While Benton believes that the methodology employed
in determining the Exchange Values is fair to Investors, resulting in valuations
that exceed the estimated liquidation values of each of the Partnerships
($324,663 for the 1989-1 Partnership, $1,145,428 for the 1990-1 Partnership and
$266,638 for the 1991-1 Partnership), these liquidation values were determined
by Benton, without an independent appraisal of such liquidation values.

         Uncertainties in the Method of Determining Exchange Values. While
Benton believes that the method of determining the Exchange Values represents a
fair, reasonable and proper method of valuing the Partnership Units, the method
of determining the Exchange Values is subject to various uncertainties and may
have resulted in a valuation that would differ from offers made by independent
bidders. The components of the Exchange Value and the factors underlying these
uncertainties are described below.

                  Other Assets and Liabilities. The method of determining the
         Exchange Values takes into account the estimated value of other assets
         and liabilities of each of the Partnerships as of March 31, 1995. In
         calculating the Exchange Values, the net book value of current assets
         and liabilities of the respective Partnerships was derived from that
         Partnership's unaudited balance sheet as of March 31, 1995, prepared on
         the accrual basis. The value of the Partnerships' wells and other
         equipment was derived from the respective Partnership's tax-basis
         balances at year end. These balances reflect the cost of the equipment
         less accumulated depreciation for tax accounting purposes. The
         tax-basis value of the equipment and the balance sheet book value of
         current assets and liabilities used by Benton in the calculation of
         Exchange Values may be higher or lower than the fair market value of
         those assets and liabilities.

                  Subsequent Events. Exchange Values will not be adjusted to
         reflect changes in the present value of the estimated future net cash
         flows attributable to the Proved Reserves of the Partnerships after
         December 31, 1994, although oil and gas prices in subsequent periods
         may differ from the prices used on the date of the reserve reports.

         No Fractional Shares. No fractional shares will be issued in connection
with the Exchange Offer. An Investor who would otherwise be entitled to a
fractional share of Common Stock will be paid cash in lieu of such fractional
shares. Warrants issued in connection with the Exchange Offer will be rounded to
the nearest whole number of Warrants and no fractional interest will be issued.

         Potential Benefits of Alternatives to the Exchange. Instead of
proposing the Exchange, Benton could instead continue to operate the
Partnerships, or with the approval of the Investors of each of the Partnerships,
seek to liquidate the Partnerships' assets and distribute the liquidation
proceeds in accordance with the provisions of the Partnership Agreements,
enabling Investors to reinvest proceeds from the asset sales in the case of a
liquidation and avoid the market risks associated with the ownership of Benton
Common Stock to be received in the Exchange. Both alternatives were rejected by
Benton based on its analysis of their comparative results and values. Benton
believes that continuation of the Partnerships would result in substantial
additional reductions in the cash distribution rates for each of the
Partnerships due primarily to expected production declines from depletion of
reserves. Benton's analysis of continuing the Partnerships in light of these
factors, based on average oil and gas prices received in 1994 and reserve data
as of December 31, 1994, reflects declines in annual distribution rates (i) per
1989-1 Unit from $600 in 1993 to $162 in 1994, to $114 in 1995, to $146 in 1996,
to $91 in 1997 and $7 in 1998, (ii) per 1990-1 Unit from $400 in 1993 to $66 in
1994, to $97 in 1995, to $119 in 1996, to $76 in 1997 and $30 in 1998, and (iii)
per 1991-1 Unit from $400 in 1993 to $300 in 1994, to $61 in 1995, to $83 in
1996, to $40 in 1997 and to $0 in 1998. However, each Partnership's future
performance will depend on actual oil and gas prices and production levels,
which could materially affect Benton's 


                                       35
<PAGE>   49

continuation analysis in either direction. In addition, the liquidation values
estimated by Benton were based on an actual third party offer received by Benton
for the purchase and sale of the Umbrella Point Field. These liquidation
valuations estimated by Benton could, however, prove to be incorrect since the
estimates are based on various pricing and other market related assumptions.

         Inherent Uncertainties in Estimating Reserves and Future Net Cash
Flows. The present value of estimated future net cash flows from the Proved
Reserves of the Partnerships, a significant factor considered in determining the
Exchange Values, cannot be determined with a high degree of certainty. There are
numerous uncertainties inherent in estimating quantities of Proved Reserves and
on projecting future rates of production, future development, recompletion and
workover expenditures, prices to be received upon the sale and costs to be
incurred in production. The data set forth in the audit letter which summarizes
the reserve report for each of the Partnerships included in Exhibit B to this
Prospectus represent estimates only and may vary materially from the quantities
of oil and gas actually recovered and the future net cash flows received upon
the sale thereof. Benton's use of these estimates in determining the Exchange
Values for the Partnerships could therefore result in an undervaluation of the
Partnership Units.

         Valuation Conflict of Interest. The determination of the Exchange
Values by Benton involves a conflict of interest because of Benton's duties as
Managing General Partner of the Partnerships and its purchase of the assets.
Accordingly, Benton's determination may not reflect the value of the
Partnership's net assets if all such assets were sold to an unaffiliated third
party in an arm's length transaction. As Managing General Partner of the
Partnerships, Benton owes fiduciary duties to the Investors, and also owes a
duty to the stockholders of Benton. While Benton believes that it has fulfilled
these obligations in its determination of the Exchange Values, no degree of
objectivity or professional competence can eliminate the inherent conflict of
interest.

         Lack of Independent Representative; No Fairness Opinion. Benton did not
engage an independent representative to negotiate the terms of the Exchange
Offer on behalf of the Investors. As a result, the Exchange Values and other
terms of the Exchange Offer may not be as favorable as the terms that an
independent representative might have obtained. In addition, Benton did not
retain an independent third party to render an opinion with regard to the
fairness of the Exchange Offer to the Investors and the Partnerships.

         Limited Dissenters' or Appraisal Rights. Investors residing in states
other than California will not be afforded any dissenters' or appraisal rights.
Under the rules adopted by the NASD, investors in roll-up transactions such as
the Exchange Offer are entitled to certain dissenters' rights unless the sponsor
adopts a 75% approval requirement for the transaction or other procedures
designed to protect the rights of investors. Although adoption of the Proposals
by each of the Partnerships would require the consent under the Partnership
Agreements of the holders of only a majority of the Partnership Units, the
Managing General Partner has adopted a 75% approval procedure instead of
providing dissenters' rights.

         Investors residing in California will be afforded limited dissenters'
rights in accordance with the requirements for roll-up transactions under the
California Code. By voting against the Proposal, Investors in the State of
California will be deemed to exercise their dissenters' rights and will receive
the number of shares of Common Stock and Warrants equal to the Exchange Value of
their interests divided by the closing price of the Common Stock on the
NASDAQ-NMS during the twenty days immediately after the Closing Date. If that
average price is lower than the Exchange Price, dissenting California Investors
will receive more shares of Common Stock than they would otherwise receive in
the Exchange Offer. California Investors hold a substantial portion of the
interests in the 1989-1 Partnership, the 1990-



                                       36
<PAGE>   50

1 Partnership and the 1991-1 Partnership and the impact of the exercise of
dissenters' rights could materially increase the number of shares of Common
Stock issued by Benton in connection with the Exchange Offer.

         Risks Relating to Certain Federal Income Tax Considerations. Upon
consummation of the Exchange, Investors will recognize gain in the amount equal
to the excess of the fair market value of the Common Stock and Warrants received
by them over their respective bases in the Partnership Units they hold. Further,
the Internal Revenue Service may seek to recharacterize the transaction as a
transfer of assets by the Partnerships in exchange for Common Stock and Warrants
and subsequent liquidation of the Partnerships and distribution of their
remaining assets. Such a recharacterization of the transaction may adversely
affect the characterization of income recognized by Investors upon consummation
of the Exchange. In addition, under such circumstances, the tax consequences
realized by an Investor consenting to the Exchange may differ from that realized
by Investors who do not participate in the Exchange but rather receive Common
Stock and Warrants upon liquidation of the Partnerships.

RISKS RELATED TO BENTON

         Losses From Operations. The historical financial data for Benton
reflect net losses of $2,909,335 and $4,828,590 for the years ended December 31,
1992 and 1993, respectively and $1,142,126 for the three months ended March 31,
1994, and net income of $2,954,161 for the year ended December 31, 1994, and
$2,041,108 for the three months ended March 31, 1995. Benton had total revenues
of $8,622,109, $7,503,796 and $34,704,806 for the years ended December 31, 1992,
1993 and 1994, respectively, and $3,682,173 and $12,661,166 for the three months
ended March 31, 1994 and 1995, respectively. The decreased revenues for the year
ended December 31, 1993 compared to the year ended December 31, 1992 was due in
part to the sale by Benton of certain non-strategic oil and gas properties.
During 1992 and 1993, Benton made a significant amount of capital expenditures
for infra-structure, production facilities, pipelines and 3-D seismic surveys.
Such expenditures did not immediately increase production from Benton's oil and
gas properties. However, Benton believes that with this infra-structure
complete, Benton will focus its capital expenditures on development of its oil
and gas properties, which Benton expects will continue the trend of increased
revenues from the year ended December 31, 1993 to December 31, 1994. As Benton's
revenues increase, and the capital expenditures related to infra-structure
decrease, Benton expects to improve its profitability. Benton's ability to
maintain its financing arrangements, produce its oil and gas reserves and
service its debt obligations would be adversely affected by a lack of
profitability. Any improvement in profitability of Benton will be dependent upon
improvement in the development of reserves, revenues from the sale of oil and
gas reserves and oil and gas pricing, and there can be no assurance that such
improvement will occur.

         Foreign Operations. During 1994, Benton derived approximately 78% of
its consolidated oil and gas revenues and approximately 97% of its Proved
Reserves from its foreign operations in Venezuela and Russia. Benton's
Venezuelan and Russian operations are subject to political, economic and other
uncertainties inherent in the development of foreign properties including,
without limitation, risks of war, revolution, expropriation, cancellation,
renegotiation or modification of existing contracts, export and transportation
regulations and tariffs, taxation and royalty policies, foreign exchange
restrictions, adverse changes in currency value, international monetary
fluctuations, environmental controls and other hazards arising out of foreign
governmental sovereignty over certain areas in which Benton plans to conduct
operations.

         Benton's operations have not been materially affected to date by
political instability or the recent banking crisis in Venezuela. Similarly, to
date, Benton's operations have not been materially adversely 


                                       37
<PAGE>   51

affected by the recent political or economic instability in Russia. However,
there can be no assurance that Benton's operations will not be materially
adversely affected by political or economic instability or burdensome taxation
in the future. Benton currently carries no insurance against political
instability. However, Benton has applied for insurance to cover the risk of
currency inconvertibility for its Venezuelan operations with the Overseas
Private Investment Corporation ("OPIC"), an agency of the United States
government. There can be no assurance that Benton will be able to obtain this
insurance.

         Benton has limited experience in conducting oil and gas operations in
Venezuela and Russia. Benton formed ventures with local partners in Venezuela
and Russia in an attempt to reduce some of the risks associated with conducting
operations in such countries and to facilitate local transactions. Benton may
encounter unforeseen difficulties in Venezuela and Russia, including problems
related to production and deliverability of oil and gas, and any such
difficulties could have a material adverse effect on Benton.

         Furthermore, the timing and extent of Benton's development activities
in Venezuela are subject to the approval of Lagoven and the Ministry of Energy
and Mines. There can be no assurance that the development activities proposed by
Benton-Vinccler will receive the necessary approval. In addition, pursuant to
the Articles of Incorporation/By-Laws of Benton-Vinccler, the consent of both
Benton and Vinccler is a prerequisite to certain corporation transactions and
other matters relating to Benton-Vinccler, including, without limitation, any
sale of corporate assets, any assignment or sub-contracting of the operating
service agreement with Lagoven, any change in Benton-Vinccler's corporate
capital, duration or corporate purpose, any merger between Benton-Vinccler and
another company as well as certain amendments to Benton-Vinccler's Articles of
Incorporation/By-Laws. There can be no assurance that Benton and Vinccler will
agree upon any such proposed transactions or matters.

         In addition to the factors discussed above, Russia has established an
export tariff on all oil exported from Russia, which, as imposed, has the effect
of reducing the cash flows and potential profits to Benton. However, Russia has
issued or drafted various decrees and legislation under which certain oil and
gas ventures, including GEOILBENT, are eligible for relief from such oil export
tariff until such time as they have recovered their capital investment.
GEOILBENT has received a waiver from the export tariff for 1995, and expects to
apply for renewal of such waiver for 1996 and 1997. However, there can be no
assurance that any such renewals can be obtained. Furthermore, after the waiver
for 1995 was issued to GEOILBENT, a new Russian law came into force which
repeals all tax and custom benefits previously granted to participants in
foreign economic activities, except for those granted pursuant to certain
federal laws, including the law "On Customs Tariff." While it is not clear
whether the repeal applies to GEOILBENT's waiver for 1995, GEOILBENT believes
that its waiver should be regarded as granted pursuant to the law "On Customs
Tariff." The legislative and regulatory environment in Russia continues to be
subject to frequent change and uncertainty.

         In addition, the license which grants GEOILBENT the right to develop
the North Gubkinskoye Field sets forth required levels of oil and gas production
through the year 2000 and requires GEOILBENT to make additional royalty payments
in the event that such production levels are not achieved during any three year
period. As a result of the recent volatility in net wellhead oil prices and the
export tariff, GEOILBENT's production for 1994 was significantly lower than that
required for 1994, and, if such adverse conditions were to continue, GEOILBENT
might produce significantly less oil and gas then required under the license
during the next few years, which could result in GEOILBENT paying significantly
higher royalties under the license.


                                       38
<PAGE>   52

         Benton will not receive distributions from GEOILBENT until it has
expended its capital requirements under the terms of the joint venture
agreement. As of March 31, 1995, Benton has spent approximately $20.1 million of
the $25.8 million it has committed to spend by the end of 1995. However, oil and
gas production in Russia has been adversely affected by recent volatility of net
wellhead oil prices and the oil export tariff. If these conditions continue,
Benton believes that the joint venture agreement may be modified to reduce that
amount or to extend the due date of its obligation and modify other terms.
Benton believes that after it has satisfied such capital commitments, 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 future development activities.

         Properties Under Development. As of December 31, 1994, approximately
79% of Benton's Proved Reserves were undeveloped and required development
activities consisting primarily of recompletions, drilling of replacement wells
and other development drilling. In addition, approximately 3% of Benton's Proved
Reserves were proved developed behind-pipe or shut-in, requiring additional
development work. As a result, Benton will require substantial capital
expenditures to develop all of its proved reserves. At December 31, 1994, the
anticipated future development costs for Proved Reserves in Venezuela, Russia
and the United States were $79.5 million, $25.4 million and $2.0 million,
respectively. Benton does not have the capital to develop all of these reserves.
Benton expects to finance these future development costs through cash flow from
operations, sales of property interests, non-recourse project financing and the
offering of debt or equity securities. If such capital is not available, Benton
will either enter into joint ventures to develop the projects, which will result
in Benton 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 profitability. In addition, Benton may not
be able to control the development activities in fields either operated by
industry partners or in which development activities are subject to approval by
its partners. If Benton and its industry partners are not able to meet the
financial and development obligations in these fields, the interests in the
affected properties may be sold, farmed out or forfeited.

         Engineers' Estimates of Reserves and Future Net Revenue. This
Prospectuses contains or incorporates by reference estimates of Benton's oil and
gas reserves and the future net revenues therefrom which have been prepared by
Benton and audited by Huddleston & Co., Inc., independent petroleum engineers.
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
government 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 and natural gas 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 82% of Benton's total Proved Reserves were non-producing as of
December 31, 1994. Therefore, Benton's actual production, revenues, severance
and excise taxes, export tariffs, development expenditures, workover and
remedial expenditures, 


                                       39
<PAGE>   53

abandonment expenditures and operating expenditures with respect to its reserves
will likely vary from such 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 and natural gas,
availability and capacity of gas gathering systems and pipelines, curtailments
in consumption by natural gas purchasers, changes in governmental regulations or
taxation and the impact of inflation on costs. The timing of actual future net
revenues 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 SEC 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.

         Development of Additional Reserves. Benton'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 Benton conducts
successful exploration or development activities or acquires properties
containing proved reserves, the proved reserves of Benton will generally decline
as reserves are produced. There can be no assurance that Benton will be able to
discover additional commercial quantities of oil and gas, or that Benton will be
able to continue to acquire interests in underdeveloped oil and gas fields and
enhance production and reserves by conducting workovers and recompletions,
drilling replacements wells and drilling development wells, or that Benton will
have continuing success drilling productive wells and acquiring underdeveloped
properties at low finding costs.

         Litigation. In June 13, 1994, certain partners in the Partnerships and
certain other investors in oil and gas limited partnerships sponsored by Benton,
including the Partnerships that are the subject of this Exchange Offer, filed
suit against Benton in the Ventura Superior Court. The allegations in the
complaint related to Benton's operation of the Partnerships and original sale of
the Partnership Units. In an effort to resolve the concerns raised by these
partners, Benton agreed to submit the matter to arbitration, conditioned upon
the execution of a mutually satisfactory arbitration agreement. After
discussions between Benton and the agent for the partners failed to produce a
satisfactory arbitration agreement, Benton filed an answer to the complaint. The
parties have now voluntarily dismissed the action and submitted the issues and
claims to arbitration. Benton believes that the allegations made by the partners
in the arbitration are without merit and intends to vigorously defend this
action.

In addition, investors in partnerships which were sponsored by a third party
have sued Benton on the theory that since it provided oil and gas drilling
prospects to those partnerships and operated substantially all of their
properties, it was responsible for alleged violations of securities laws in
connection with the offer and sale of interests, contractual breach of fiduciary
duty and fraud. See "The Exchange Offer and Proposal--Litigation and Related
Matters."

         Retention and Attraction of Key Personnel. Benton 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 Benton's
business. In an effort to minimize the risk, Benton 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. Furthermore, as a result of
Benton's recent growth, Benton currently is seeking additional accounting and
operating personnel. There can be no assurance that 


                                       40
<PAGE>   54

Benton 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 Benton.

RISKS RELATED TO THE OIL AND GAS INDUSTRY

         Risk of Oil and Gas Operations. Benton'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 damages and other damage to the properties of Benton or
others. In addition, because Benton acquires interests in underdeveloped oil and
gas fields that have been operated by others for many years, Benton may be
liable for any damage or pollution caused by any prior operations of such oil
and gas fields. Moreover, offshore operations are subject to a variety of
operating risks peculiar to the marine environment--such as hurricanes or other
adverse weather conditions--to more extensive governmental regulation, including
certain regulations that may, in certain circumstances, impose absolute
liability for environmental damage, and to interruption or termination of
business activities by government authorities based upon environmental or other
considerations. In accordance with customary industry practice, Benton is not
fully insured against these risks, nor are all such risks insurable.
Accordingly, there can be no assurance that such insurance as Benton 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 Benton. 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
governmental regulations, the price and availability of alternative fuels and
overall economic conditions. Lower oil and natural gas prices also may reduce
the amount of Benton's oil and natural gas that is economic to produce. In
addition, the marketability of Benton's production depends upon the availability
and capacity of gas gathering systems and pipelines.

         Government Regulation; Environmental Risks. Benton'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 Benton'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
Benton. Compliance with environmental requirements generally could have a
material adverse effect upon the capital expenditures, earnings or competitive
position of Benton.

         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 


                                       41
<PAGE>   55

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 Benton's competitors have greater financial and other
resources than does Benton.

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

         Benton's policy is to retain its earnings to support the growth of
Benton's business. Accordingly, the Board of Directors of Benton has never
declared cash dividends on its Common Stock and does not plan to do so in the
foreseeable future. Furthermore, the terms of Benton's debt agreements prohibit
the payment of cash dividends on Benton's Common Stock.

         The Partnerships do make cash distributions to the Investors from
Partnership cash flow. The following table sets forth the amount of cash
distributions paid per Unit by each Partnership to its Investors during the
periods indicated.

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

         The last cash distribution made by any of the Partnerships was in
August 1994. The reasons for the lack of distributions include (i) declining oil
and gas production combined with higher lease operating expenses and production
taxes for 1994, compared to 1993; (ii) continued capital expenditures at the
Umbrella Point Field; and (iii) lower natural gas prices. As an example, the
Umbrella Point Field's natural gas price ranged from $1.84 to $2.77 per Mcf for
1993, compared to $1.47 to $2.42 per Mcf for 1994. During the first four months
of 1995, natural gas prices at Umbrella Point Field have continued to decline to
a range of $1.43 to $1.61 per Mcf.

         On July 24, 1995, the last full trading day preceding the filing of the
Exchange Offer, the closing price of Benton's Common Stock on the NASDAQ-NMS was
$12.375 per share.

         Because the market price for Benton's Common Stock is subject to
fluctuation, the total Exchange Value that an Investor will receive in
connection with the Exchange Offer may increase or decrease prior to the
Exchange. Holders of Partnership Units are urged to obtain current market
quotations for the Benton Common Stock.

                          BACKGROUND OF EXCHANGE OFFER

1989 - 1 PARTNERSHIP

         The 1989-1 Partnership commenced business on September 1, 1989, the
effective date the 1989-1 Partnership was formed. Benton, as managing general
partner and sponsor of the 1989-1 Partnership, sold an aggregate of $1,409,091
in 1989-1 Units. At March 31, 1995, total cash distributions to holders of
1989-1 Units was $848,836. The 1989-1 Partnership owns a 4.93% working interest
in the Umbrella Point Field located in the northern end of Upper Galveston Bay,
in Texas state waters. The 1989-1 Partnership also owns a 6.57% working interest
in East Cameron Block 229, located off the coast of Grand Chenier, Louisiana in
the Gulf of Mexico. As of April 1995, the Umbrella Point Field had ten wells
producing at combined average daily rates of 342 Bbl of oil and 3.4 MMcf of
natural gas. At January 1, 1995, the 1989-1 Partnership's interest in East
Cameron Block 229 was determined to be uneconomic. See "Information Concerning
1989-1 Partnership - Description of Oil and Gas Properties."

         The 1989-1 Partnership has paid cumulatively $3,012 in cash
distributions per 1989-1 Unit to date. Since inception through December 31,
1994, the 1989-1 Partnership has produced and sold approximately 215,196 Mcf
of natural gas and 29,044 Bbl of oil.

         Since 1993, the Partnerships' oil production volumes have declined from
peak levels reached in 1992. Gas production began to decline in 1994. These
reductions are due to the natural decline occurring in the Umbrella Point Field,
the Partnerships' most significant asset. Production volumes are expected to
decline further in subsequent periods due to ongoing depletion of the
Partnerships' wells.

         The total amount of reserves encountered by and economically produced
from the wells acquired or drilled was substantially less than anticipated. In
addition, recent fluctuations in gas prices has impacted the 1989-1
Partnership. Prices received for the sale of natural gas from the Umbrella Point
Field, the most significant Partnership property, ranged from $1.84 to $2.77 per
Mcf during 1993, compared to $1.47 to $2.42 per Mcf during 1994. During the
first four months of 1995, prices received for the sale of natural gas from the
Umbrella Point Field has continued to decline to a range of $1.43 to $1.61 per
Mcf. During these periods of declining natural gas prices, the 1989-1
Partnership's cash flow was reduced while operating costs and third party costs
did not decline. Also as a result of lower natural gas prices, the amount of the
1989-1 Partnership's reserves that can be produced economically is reduced
substantially.

         In addition, many of the Investors in the 1989-1 Partnership have
expressed concern regarding the historical performance and continued operation
of the 1989-1 Partnership and its properties. See "The Exchange Offer and
Proposal--Litigation and Related Matters." In response to these concerns, the
Managing General Partner analyzed and evaluated the 1989-1 Partnership's
original objectives, current status and future prospects. The Managing General
Partner retained an independent petroleum engineer to prepare an updated
estimate of the remaining reserves of the 1989-1 Partnership properties and
the value of such reserves. In addition, the Managing General Partner made
available to third parties the 1989-1 Partnership well, production, reserve
and property information for the purpose of soliciting third party bids for the
purchase of the 1989-1 Partnership's assets. See "Reasons for the Exchange
Offer--Recommendation of the Managing General Partner--Alternatives to the
Exchange" for a discussion of the third party bids received by the Managing
General Partner.

        As the Private Placement Memorandum used to sell the 1989-1 Units
explained, oil and gas exploration and production have many risks, including the
risk that exploring for and producing natural gas and oil is highly speculative.
The search for oil and gas can result in unprofitable efforts not only from the
drilling of dry holes but from wells which, although initially productive, do
not produce oil and gas in sufficient amounts to return a profit on the costs
expended. In addition, there is a risk that oil and gas prices could decline and
the quantities of oil and gas discovered might not be sufficient to return the
initial investment. Based on the geological and geophysical information
available prior to the drilling and acquisition of the 1989-1 Partnership's
properties, the Managing General Partner believed that the 1989-1
Partnership's wells would be able to provide economic benefit. However, based on
the current evaluation of the 1989-1 Partnership reserves and future
prospects, the Managing General Partner believes the most logical economic
course is to exchange the remaining assets as soon as possible pursuant to the
terms of the Exchange Offer.

1990 - 1 PARTNERSHIP

         The Partnership commenced business on November 29, 1990, the effective
date the 1990-1 Partnership was formed. Benton, as managing general partner
and sponsor of the 1990-1 Partnership, sold an aggregate of $7,095,960 of 1990-1
Units. Through March 31, 1995, the Partnership has made cash distributions in
the aggregate of $2,452,364. The 1990-1 Partnership purchased an 8.4% working
interest in 32 producing wells in the Round Mountain Field, located in the San
Joaquin Basin of California. The 1990-1 Partnership sold its interest in Round
Mountain in September 1992. The 1990-1 Partnership owned a 38% working interest
in the Hopper Canyon 12-1 well, located in Ventura County, California. In April
1992, the 1990-1 Partnership sold its interest in the well to Fortune Petroleum
for cash and shares of common stock, which were subsequently sold. The 1990-1
Partnership also owned a 44.67% working interest in the North Fisher Reef No.
13-16A well. Although this prospect had multiple objectives, all objectives were
determined to be non-commercial and the well was plugged and abandoned. The
1990-1 Partnership had a 12.5% working interest in the Prather 43-1 well. Once
the well was drilled to total depth, it was determined to be uneconomic and was
plugged and abandoned.

         The 1990-1 Partnership currently owns a 14.19% working interest in the
Umbrella Point Field located in the Upper Galveston Bay, in Texas state waters.
The Partnership also owns a 22.85% working interest in the East Cameron Block
229, located off the coast of Grand Chenier, Louisiana in the Gulf of Mexico. As
of April 1995, the Umbrella Point Field had ten wells producing at combined
average daily rates of 342 Bbl of oil and 3.4 MMcf of natural gas. At January 1,
1995, the 1990-1 Partnership's interest in East Cameron Block 229 was determined
to be uneconomic. See "Information Concerning 1990-1 Partnership-Description of
Oil and Gas Properties."

         The 1990-1 Partnership originally purchased a 0.38% working interest in
the West Cote Blanche Bay Field, located in a shallow bay in St. Mary Parish,
Louisiana. In 1991, the Partnership sold a 0.06% working interest in the West
Cote Blanche Bay Field to the 1991-1 Partnership. In March 1995, the Partnership
sold its 0.32% working interest in wells above the depth of approximately 10,575
feet. As of April 1995, the 1990-1 Partnership currently owns a 0.32% working
interest in 3 wells in the West Cote Blanche Bay Field which are currently
producing at a combined rate of approximately 7 MMcf of natural gas per day. See
"Information Concerning 1990-1 Partnership - Description of Oil and Gas
Properties."

         Since 1993, the Partnerships' oil production volumes have declined from
peak levels reached in 1991 and 1992. Gas production began to decline in 1994.
These reductions are due to the natural decline occurring in the Umbrella Point
Field, the Partnerships' most significant asset. Production 


                                       46
<PAGE>   60

volumes are expected to decline further in subsequent periods due to ongoing
depletion of the Partnerships' wells.

         The 1990-1 Partnership has paid cumulatively $1,728 in cash
distributions per 1990-1 Unit to date. Since inception through December 31,
1994, the 1990-1 Partnership has produced and sold approximately 615,027 Mcf
of natural gas and 102,165 Bbl of oil.

         The total amount of reserves encountered by and economically produced
from the wells acquired or drilled was substantially less than anticipated. In
addition, recent fluctuations in gas prices has impacted the 1990-1
Partnership. Prices received for the sale of natural gas from the Umbrella Point
Field, the most significant Partnership property, ranged from $1.84 to $2.77 per
Mcf during 1993, compared to $1.47 to $2.42 per Mcf during 1994. During the
first four months of 1995, prices received for the sale of natural gas from the
Umbrella Point Field has continued to decline to a range of $1.43 to $1.61 per
Mcf. During these periods of declining natural gas prices, the 1990-1
Partnership's cash flow was reduced while operating costs and third party costs
did not decline. Also as a result of lower natural gas prices, the amount of the
1990-1 Partnership's reserves that can be produced economically is reduced
substantially.

         In addition, many of the Investors in the 1990-1 Partnership have
expressed concern regarding the historical performance and continued operation
of the 1990-1 Partnership and its properties. See "The Exchange Offer and
Proposal -- Litigation and Related Matters." In response to these concerns, the
Managing General Partner analyzed and evaluated the 1990-1 Partnership's
original objectives, current status and future prospects. The Managing General
Partner retained an independent petroleum engineer to prepare an updated
estimate of the remaining reserves of the 1990-1 Partnership properties and
the value of such reserves. In addition, the Managing General Partner made
available to third parties the 1990-1 Partnership well, production, reserve
and property information for the purpose of soliciting third party bids for the
purchase of the 1990-1 Partnership's assets. See "Reasons for the Exchange
Offer -- Recommendation of the Managing General Partner -- Alternatives to the

General Partner.

terms of the Exchange Offer.

1991-1 PARTNERSHIP

         The Partnership commenced business on July 30, 1991, the effective date
the 1991-1 Partnership was formed. Benton, as managing general partner and
sponsor of the 1991-1 Partnership, sold an aggregate of $1,409,091 of 1991-1
Units. At March 31, 1995, the 1991-1 Partnership had distributed an aggregate of
$338,182 to participants. The 1991-1 Partnership owned a 38.0% working interest
in the 


                                       47
<PAGE>   61

Hopper Canyon 12-1 well, located in Ventura County, California. The 1991-1
Partnership subsequently sold its interest in this well to Fortune Petroleum,
for cash proceeds and shares of common stock, which were subsequently sold. The
1991-1 Partnership also owned a 17.5% working interest in the Prather 43-1 well,
located in Acadia Parish, Louisiana. This well was drilled to total depth and it
was determined to be uneconomical, and was therefore plugged and abandoned.

         The 1991-1 Partnership owns a 2.83% working interest in the Umbrella
Point Field, located in the Upper Galveston Bay, in Texas state waters. As of
April 1995, the Umbrella Point Field had 10 wells producing at combined average
daily rates of 342 Bbl of oil and 3.4 MMcf of natural gas.

         The 1991-1 Partnership purchased a 0.06% working interest in the West
Cote Blanche Bay Field, located in a shallow bay in St. Mary Parish, Louisiana,
from the 1990-1 Partnership. In March 1995, the Partnership sold its 0.06%
working interest in certain depths (above approximately 10,575 feet) in the West
Cote Blanche Bay Field. The 1991-1 Partnership has a 0.06% working interest in 3
wells below the depth of approximately 10,575 feet. These wells are currently
producing at a combined rate of approximately 7 MMcf of natural gas per day. See
"Information Concerning 1991-1 Partnership -- Description of Oil and Gas
Properties."

         Since 1993, the Partnerships' oil production volumes have declined from
peak levels reached in 1992. Gas production declined in 1993. These reductions
are due to the natural decline occurring in the Umbrella Point Field, the
Partnerships' most significant asset. Production volumes are expected to decline
further in subsequent periods due to ongoing depletion of the Partnerships'
wells.

         The 1991-1 Partnership has paid cumulatively $1,200 in cash
distributions per 1991-1 Unit to date. Since inception through December 31,
1994, the 1991-1 Partnership has produced and sold approximately 69,222 Mcf of
natural gas and 15,109 Bbl of oil.

         The total amount of reserves encountered by and economically produced
from the wells acquired or drilled was substantially less than anticipated. In
addition, recent fluctuations in gas prices has impacted the 1991-1
Partnership. Prices received for the sale of natural gas from the Umbrella Point
Field, the most significant Partnership property, ranged from $1.84 to $2.77 per
Mcf during 1993, compared to $1.47 to $2.42 per Mcf during 1994. During the
first four months of 1995, prices received for the sale of natural gas from the
Umbrella Point Field has continued to decline to a range of $1.43 to $1.61 per
Mcf. During these periods of declining natural gas prices, the 1991-1

the value of such reserves. In addition, the Managing General Partner made
available to third parties the 1991-1 Partnership well, production, reserve
and property information for the purpose of soliciting third party bids for the

GOLDKING OFFER

         In June 1995, Benton received an offer from Goldking to purchase all of
the right, title and interest owned by each of the Partnerships and Benton in
the Umbrella Point Field. Goldking made a similar offer to all other working
interest owners in the Umbrella Point Field. Goldking's intent is to own 100% of
the working interests in the Field. To obtain financing for the purchase of the
working interests, Goldking was required to acquire not less than a 75% working
interest in the Field. In order to preserve the offer for the Partnerships,
Benton sold its corporate interest in the Umbrella Point Field (11.77% working
interest) for $756,872. Benton entered into agreements, on behalf of each of the
Partnerships, with Goldking for the sale of the Partnerships' interests in the
Umbrella Point Field, subject to approval of the Partnerships. In consideration
of this sale, the 1989-1 Partnership, the 1990-1 Partnership and the 1991-1
Partnership would receive anticipated net proceeds determined as of March 31,
1995 in the aggregate of $375,643, $1,081,589 and $215,280, respectively, if the
sale were consummated, subject to adjustments for revenues, expenses and capital
expenditures after that date.

                         THE EXCHANGE OFFER AND PROPOSAL

DESCRIPTION OF THE EXCHANGE OFFER

         General. Benton is offering to exchange Common Stock and Warrants for
Partnership Units in the 1989-1 Partnership, the 1990-1 Partnership and the
1991-1 Partnership (the "Exchange"). Investors who tender their Partnership
Units will receive the number of shares of Common Stock and Warrants set forth
below for the respective Partnership Units. In connection with the Exchange
Offer, Benton is submitting Proposals to Investors in each of the Partnerships
to amend the respective Partnership Agreements to provide for the transfer of
all of the assets and liabilities of the Partnerships to Benton as of the
December 31, 1994 Effective Date in exchange for Common Stock and Warrants in
the amounts set forth below and the pro rata distribution of such consideration
in liquidation of the Partnership.

         1989-1 Partnership. If the Exchange Offer is consummated, each holder
of a 1989-1 Unit who tenders his Units in connection with the Exchange Offer
will receive 104 shares of Common Stock. Fractional shares of Common Stock will
not be issued in connection with the Exchange Offer or liquidation of the 1989-
1 Partnership. A Partner in the 1989-1 Partnership otherwise entitled to a
fractional share of Common Stock will be paid in cash in lieu of such fractional
shares.

         1990-1 Partnership. If the Exchange Offer is consummated, each holder
of a 1990-1 Unit who tenders his Units in connection with the Exchange Offer
will receive (i) 77 shares of Common Stock and (ii) Warrants to purchase 249
shares of Common Stock with an exercise price of $12.37 per share. Fractional
shares of Common Stock will not be issued in connection with the Exchange Offer
or liquidation of the 1990-1 Partnership. A Partner in the 1990-1
Partnership otherwise entitled to a fractional share of Common Stock will be
paid in cash in lieu of such fractional shares. Warrants to be issued will be
rounded to the nearest whole number of Warrants and no fractional interests will
be issued.

         1991-1 Partnership. If the Exchange Offer is consummated, each holder
of a 1991-1 Unit who tenders his Units in connection with the Exchange Offer
will receive (i) 92 shares of Common Stock and (ii) Warrants to purchase 282
shares of Common Stock with an exercise price of $12.37 per share. Fractional
shares of Common Stock will not be issued in connection with the Exchange Offer
or liquidation of the 1991-1 Partnership. A Partner in the 1991-1
Partnership otherwise entitled to a fractional share of Common Stock will be
paid in cash in lieu of such fractional shares. Warrants to be issued will be
rounded to the nearest whole number of Warrants and no fractional interests will
be issued.

THE PROPOSAL

         Description of Proposal. Benton is submitting to the Investors in each
of the Partnerships the proposal to adopt an amendment to each of the
Partnerships' Partnership Agreements annexed as Exhibit C to this Prospectus.
The respective amendments, if adopted by each of the Partnerships in accordance
with the amendment procedures in the Partnership Agreement will provide for the
following steps:

    *    The transfer to Benton in exchange for the Common Stock and Warrants
         set forth below, of all of the assets of the Partnership and the
         assumption by Benton of all liabilities of the Partnership effective as
         of the Effective Date.


                                       50
<PAGE>   64

   *     The dissolution of each of the Partnerships and the distribution to
         the Investors of the Common Stock and Warrants allocable to their
         interests in liquidation promptly following the Closing Date.

         Each Investor who tenders his Partnership Units pursuant to the
Exchange Offer will by that tender, consent to the proposal for that
Partnership. If a Partnership adopts the proposal by the consent of 75% of the
Partnership Units for the respective Partnership, all Investors in that
Partnership, whether or not they tendered their Units in the Exchange Offer,
will receive the same amount of Common Stock and Warrants as they would have
received had they tendered their Partnership Units. Consummation of the Exchange
Offer for a partnership is conditioned upon approval by that partnership of the
proposal. Approval of the proposal and adoption of the Exchange Offer is not
conditioned upon approval or acceptance by any other partnership. Investors who
do not return a completed Letter of Transmittal will not receive Benton Common
Stock or Warrants until Benton has distributed immediately after the closing
date and investors have return an executed Transfer Application issuable to them
in the exchange, which may result in a delay in receiving the Common Stock and
Warrants if the transfer application is not properly returned.

         Timing of Common Stock Issuance. Assuming that the proposal is adopted
and the Exchange Offer is consummated, Benton will have the benefit of each of
the Partnership's assets and associated cash flows commencing on the effective
date of December 31, 1994. The Common Stock and Warrants issued in the exchange
will be freely transferable immediately following issuance.

         On the Closing Date, Benton will cause certificates representing the
Common Stock and the Warrants issuable in the Exchange to be registered in the
name of the holders who have accepted the Exchange Offer. Benton will also cause
a certificate representing the shares of Common Stock and Warrants that will be
issued to participants upon liquidation of each of the Partnerships to be issued
in the name of the Partnership, pending dissolution, liquidation and winding-up
of the Partnerships. Immediately thereafter, Benton will cause the shares of
Common Stock and Warrants issued in the name of the Partnership to be
transferred into certificates representing Common Stock and Warrants, registered
in the names of the individual participants remaining in the Partnerships
following liquidation.

         Conditions. Benton may, in it sole discretion, at any time on or prior
to the closing date, refuse to consummate, abandon or terminate the exchange
offer and withdraw the proposal if after the date of this prospectus, in the
sole judgment of Benton, a material change shall have occurred or been
threatened (or any development shall have occurred or been threatened involving
a prospective material change) affecting (or likely to affect) the business or
properties of Benton or the partnerships or if Benton shall have become aware of
any facts or circumstances that have or may have material significance with
respect to Benton's operations. If any event shall occur or any matter shall
have been brought to the attention of Benton, that, in the sole judgment of
Benton materially affects the partnerships, whether adversely or otherwise, or
the exchange offer for interest in the partnerships, Benton may refuse to accept
tenders of interest in the partnerships, or may modify or amend the Exchange
Offer to take the event or matter into account.

         The absence of the material change affecting Benton or the Partnerships
is the only material condition to the exchange offer. If that condition has not
been fulfilled or the exchange offer is withdrawn by Benton, each letter of
transmittal tendering an interest or consenting to the proposal will be void and
no Common Stock or Warrants will be issued in exchange for the interests in the
respective partnership.

DISSENTERS' RIGHTS

         Investors residing in states other than California will not be afforded
any dissenters' or appraisal rights. Under the rules adopted by the National
Association of Securities Dealers, Inc., ("NASD"), investors in roll-up
transactions such as the Exchange Offer are entitled to certain dissenters'
rights unless the sponsor adopts a 75% approval requirement for the transaction
or other procedures designed to protect the rights of investors. Although
adoption of the Proposals by each of the Partnerships would require the consent
under the Partnership Agreements of the holders of only a majority of the
Partnership Units, the Managing General Partner has adopted a 75% approval
procedure instead of providing dissenters' rights.

         Investors residing in California will be afforded limited dissenters'
rights in accordance with the requirements for roll-up transactions under the
California Code. By voting against the Proposal, Investors in the State of
California will be deemed to exercise their dissenters' rights and will receive
the number of shares of Common Stock and Warrants equal to the Exchange Value of
their interests divided by the closing price of the Common Stock on the
NASDAQ-NMS during the twenty days immediately after the Closing Date. If that
average price is lower than the Exchange Price, dissenting California Investors
will receive more shares of Common Stock than they would otherwise receive in
the Exchange Offer. California Investors hold a substantial portion of the
interests in the 1989-1 Partnership, the 1990-1 Partnership and the 1991-1
Partnership and the impact of the exercise of dissenters' rights could
materially increase the number of shares of Common Stock issued by Benton in
connection with the Exchange Offer.

DISTRIBUTION OF COMMON STOCK AND WARRANTS

         Each Investor who returns a completed Letter of Transmittal, even if he
withholds consent to the Proposal, will thereby have provided to Benton the
necessary information to issue the Common Stock and Warrants provided the
Exchange Offer is consummated. Assuming that the Proposals are adopted by the
Partnerships and the Exchange Offer is consummated, Investors who have returned
a completed Letter of Transmittal will receive the Common Stock and Warrants
issuable to them in the Exchange promptly after the Closing Date.

         An Investor who does not return a completed Letter of Transmittal will
not be eligible to receive the Common Stock and Warrants after the Closing Date.
Instead, the Common Stock and Warrants, attributable to that Investor's
Partnership Units will be held of record by the respective Partnerships.
Immediately after the Closing Date, Benton will deliver a Transfer Notice to
each Investor who has not returned a Letter of Transmittal. The Transfer Notice
should be completed and returned to Benton promptly. Upon return of the executed
Transfer Notice, Benton will have the Common Stock and Warrants transferred and
delivered to the Investor.

ELECTION TO RECEIVE CASH IN LIEU OF COMMON STOCK

         Holders of Units in the Partnerships who elect to accept the Exchange
Offer may elect to receive cash in lieu of shares of Common Stock to be issued,
BUT CASH WILL BE DISTRIBUTED TO HOLDERS MAKING SUCH ELECTION ONLY IF THE SALE OF
THE UMBRELLA POINT FIELD TO GOLDKING, AS DESCRIBED HEREIN, IS ACTUALLY
CONSUMMATED. If the sale of the Umbrella Point Field working interests to
Goldking is consummated, a holder who elects to receive cash in lieu of Common
Stock will receive $1,292 for each 1989-1 Unit, $957 for each 1990-1 Unit and
$1,146 for each 1991-1 Unit, with Warrants in the amounts described herein.
There can be no assurance from Benton that the sale of the Umbrella Point Field
to 


                                       52
<PAGE>   66

Goldking will be consummated, and therefore, an Investor should make a decision
to accept the Exchange Offer based solely upon a decision to receive Common
Stock and Warrants in the amounts set forth herein.

INTERESTS OF CERTAIN PERSONS IN THE EXCHANGE AND PROPOSALS

         In considering the recommendation of the Managing General Partner, the
Investors should be aware that the Managing General Partner has interests in the
Exchange that are in addition to the interests of the Partnerships and the
Investors generally. Benton is the Managing General Partner of each of the
Partnerships and its determination of the Exchange Values involves an inherent
conflict of interest. As Managing General Partner, Benton owes fiduciary duties
to the Investors in the Partnerships. In addition, it owes a duty to its
stockholders. While Benton believes that it has fulfilled these obligations in
its determination of the Exchange Values, which is supported, in part, by a
reserve report audited by an independent petroleum engineer, no degree of
objectivity or professional competence can eliminate the inherent conflict of
interest.

RESALE OF BENTON COMMON STOCK

         The issuance of the Benton Common Stock to be received by the Investors
who tender their Partnership Units and the shares to be received by Investors in
liquidation of the Partnerships, as well as the issuance of the Common Stock
upon exercise of the Warrants, has been registered under the Securities Act.
Such shares may be traded freely and without restriction by those Investors of
the Partnerships not deemed to be "affiliates" of the Partnerships, as that term
is defined in the rules under the Securities Act. "Affiliates" are generally
defined as persons who control, are controlled by or are under common control
with the Partnership at the time of the Exchange. Accordingly, "affiliates"
generally will include the Managing General Partner and any Investor who owns in
excess of 10% of the Partnership interests. Benton Common Stock received by
those Investors who are deemed to be "affiliates" of a Partnership may be resold
without registration as provided by Rules 144 and 145, or as otherwise
permitted, under the Securities Act. This Prospectus does not cover any resales
of Benton Common Stock received by affiliates of the Partnerships or by certain
family members or related interests. Any Investor who becomes an affiliate of
Benton will be subject to similar restrictions under Rule 144.

FRACTIONAL SHARES

         No fractional shares of Benton Common Stock will be issued. Fractional
share interests which would otherwise be issuable shall entitle the holder
thereof to receive, in lieu of such fractional interest, an amount of cash equal
to the product of such fraction multiplied by the closing price of the Benton
Common Stock on the NASDAQ-NMS on the Closing Date. Warrants to be issued will
be rounded to the nearest whole number of Warrants and no fractional interests
will be issued.

STOCK EXCHANGE LISTING

         All of the currently issued and outstanding shares of Common Stock of
Benton are admitted for trading and quoted on the NASDAQ-NMS, and application
has been made to the NASDAQ-NMS for admission for trading of the shares of
Common Stock to be issued in connection with the Exchange Offer and the shares
of Common Stock issuable upon exercise of the Warrants. There is currently no
trading market for the Warrants, and Benton does not expect a trading market to
develop.

ACCOUNTING TREATMENT

         The Exchange will be accounted for as a purchase by Benton.
Accordingly, the purchase price will be allocated to assets and liabilities
based on their estimated fair values as of the date of acquisition.

CLOSING DATE

         The Exchange Offer is expected to be consummated on the Closing Date,
which will be no more than five days following the Expiration Date. Benton may
withdraw the Exchange Offer at any time prior to the Expiration Date under
certain circumstances, including the existence of any state or federal statute,
rule, regulation or order, or entry of any judicial or administrative order that
would prohibit the transactions contemplated by the Exchange Offer and the
Proposals.

         1989-1 Partnership. The Exchange Offer to the 1989-1 Partnership is
conditioned upon consent of 75% of the 1989-1 Units to the 1989-1 Proposal
and the absence of any material adverse development affecting the 1989-1
Partnership, as determined by Benton in its sole discretion. On the Closing
Date, subject to satisfaction of these conditions, Benton intends to accept all
1989-1 Units validly tendered and not withdrawn pursuant to the Exchange
Offer.

         1990-1 Partnership. The Exchange Offer to the 1990-1 Partnership is
conditioned upon consent of 75% of the 1990-1 Units to the 1990-1 Proposal
and the absence of any material adverse development affecting the 1990-1
Partnership, as determined by Benton in its sole discretion. On the Closing
Date, subject to satisfaction of these conditions, Benton intends to accept all
1990-1 Units validly tendered and not withdrawn pursuant to the Exchange
Offer.

         1991-1 Partnership. The Exchange Offer to the 1991-1 Partnership is
conditioned upon consent of 75% of the 1991-1 Units to the 1991-1 Proposal
and the absence of any material adverse development affecting the 1991-1
Partnership, as determined by Benton in its sole discretion. On the Closing
Date, subject to satisfaction of these conditions, Benton intends to accept all
1991-1 Units validly tendered and not withdrawn pursuant to the Exchange
Offer.

OPERATIONS AFTER THE EXCHANGE

         Benton is an independent oil and gas company engaged in the acquisition
of producing properties and exploration, development and production of oil and
gas, primarily in the eastern region of Venezuela, the Gulf Coast of Louisiana
and the West Siberia region of Russia. Upon consummation of the Exchange, Benton
intends to sell the working interests in the Umbrella Point Field to Goldking on
the terms described herein. If, however, such sale is not consummated, Benton
will operate the acquired Partnership assets as it operates its oil and gas
properties, or may sell those assets to another third party.

EXPENSES; FEES

         All expenses incurred in connection with the Exchange Offer and the
Proposals and the transactions contemplated thereby will be paid by Benton.
Benton will pay the expenses incurred in connection with tender offer to the
Investors of the Partnerships and will pay all fees and expenses in connection
with this Prospectus, including fees and expenses payable in connection with the
Registration Statement of which this Prospectus is a part.


                                       54
<PAGE>   68

BENTON'S DIVIDEND POLICY

         Benton's policy is to retain its earnings to support the growth of
Benton's business. Accordingly, the Board of Directors of Benton has never
declared cash dividends on its Common Stock and does not plan to do so in the
foreseeable future. Furthermore, the terms of a note agreement prohibit the
payment of cash dividends on Benton's Common Stock.

LITIGATION AND RELATED MATTERS

         On June 13, 1994, certain partners in the Partnerships and certain
other investors in oil and gas limited partnerships sponsored by Benton,
including the Partnerships that are the subject of this Exchange Offer, filed
suit against Benton in the Ventura Superior Court. The allegations in the
complaint related to Benton's operation of the Partnerships and original sale of
the Partnership Units. In an effort to resolve the concerns raised by these
partners, Benton agreed to submit the matter to arbitration, conditioned upon
the execution of a mutually satisfactory arbitration agreement. After
discussions between Benton and the agent for the partners failed to produce a
satisfactory arbitration agreement, Benton filed an answer to the complaint. The
parties have now voluntarily dismissed the action and submitted the issues and
claims to arbitration. Benton believes that the allegations made by the partners
in the arbitration are without merit and intends to vigorously defend this
action.

         Acceptance of the Exchange Offer and approval of the Proposals by the
Investors of the Partnerships will result in the dissolution of any Partnership
obtaining such approval and the net proceeds from the Exchange will be
distributed, in liquidation, to the Investors of such Partnership who did not
tender their Partnership Units. YOUR CONSENT TO THE PROPOSAL MAY AFFECT YOUR
RIGHTS IN THE ARBITRATION DISCUSSED ABOVE AND EACH INVESTOR IS ENCOURAGED TO
CONSULT HIS OR HER LEGAL ADVISOR TO DETERMINE THE EFFECT OF ANY CONSENT ON THE
PROPOSAL.

                      METHOD OF DETERMINING EXCHANGE VALUES

GENERAL

         The Exchange Values have been assigned to the Partnership Units to
determine the number of shares of Common Stock and Warrants to be offered for
each Partnership Unit. The Exchange Values were determined by Benton and are not
the result of negotiations with independent representatives of the Partnerships.
Accordingly, the Exchange Values may not reflect the value of the Partnership
Units or the value of the Partnership properties if all the assets were to be
sold to an unaffiliated third party in an arm's length transaction. Benton did
seek third party bids for the sale of the Partnerships' assets and received an
offer to purchase the Partnerships' working interests in the Umbrella Point
Field from Goldking. The Exchange Values are based in part on this third party
offer. Management of Benton has substantial experience in evaluating and
operating oil and gas properties in the Partnerships' production areas and
believes on the basis of that experience that the methodology employed in
determining the Exchange Values is fair to Investors and considered in the oil
and gas industry as being favorable to sellers of producing properties.

         The number of shares of Common Stock and Warrants to be issued pursuant
to the Exchange Offer has been determined relative to a Total Exchange Value
assigned to the 1989-1 Partnership Units, the 1990-1 Partnership Units and
the 1991-1 Partnership Units aggregating $364,226, $2,553,119, and $591,623,
respectively. The number of shares of Common Stock offered in exchange for
Partnership Units has been determined by dividing the Exchange Value of the
tangible assets of the Partnership by a Common Stock price of $12.37, subject to
rounding adjustments. The Common Stock price is based upon the closing price of
the Common Stock on NASDAQ-NMS on July 17, 1995 and will not reflect any
subsequent increase or decrease in the market price for the Common Stock after
that date, except to the extent required by dissenters' rights for California
residents. The number of Warrants to be assigned to each Partnership Unit was
determined by dividing the estimated value of the General Intangibles of the
Partnership by the estimated present value per Warrant. Benton has used the
Black-Scholes option pricing model to calculate the present value of the
Warrants, which yielded a value of $3.38 per Warrant. The Warrants are
exercisable at a price of $12.37 per share and will expire three years from the
date of issuance.

         The most significant assets considered in determining the Exchange
Values were the anticipated cash proceeds from the sale of Umbrella Point Field
and the Proved Reserves of the Partnerships. The Exchange Values reflect these
oil and gas assets and all other assets and liabilities of the Partnerships.
These components reflect (i) the estimated cash proceeds from the sale of
Umbrella Point Field to Goldking, (ii) the estimated present value of future net
cash flows from Proved Reserves of the Partnership as of December 31, 1994,
discounted 10% per year and calculated without escalation of prices and costs,
(iii) the net book value of current assets and liabilities of the Partnership as
of March 31, 1995, (iv) the tax-basis balances of equipment as of December 31,
1994, and (v) the General Intangibles of the Partnership. Based on management's
experience in evaluating reserve acquisition opportunities and transactions in
the Partnerships' production areas, Benton believes that the components of the
Exchange Values reflect all appropriate valuation criteria for the Partnerships
in accordance with industry practice. Each component of the Exchange Value,
estimated on the basis of interim data, is presented for each of the
Partnerships in the tables and discussions below.

1989-1 PARTNERSHIP EXCHANGE VALUE COMPONENTS

         General. The following table sets forth each of the Exchange Value

</TABLE>

         Other Assets and Liabilities. The tax-basis balances of the 1989-1
Partnership's equipment, excluding Umbrella Point field equipment, aggregated
$4,563 at December 31, 1994, and the net book value of its current assets and
liabilities as of March 31, 1995 reflect a deficit of $15,980 after deducting
1994 distributions aggregating $45,655. The equipment value and current net
assets are based upon the 1989-1 Partnership's 1994 year-end tax accounting
records and March 31, 1995 unaudited financial statements, respectively,
maintained in accordance with the applicable provisions of the 1989-1
Partnership Agreement.

         Benton believes that valuing the 1989-1 Partnership's equipment
(comprised of oil and gas production and transportation facilities) at its tax-
basis balances is favorable to the sellers of the producing properties since
many purchasers in transactions evaluated by Benton, as part of its on-going
involvement in the production area, allocate nominal value to well equipment on
the theory that its salvage value at the end of the commercial lives of acquired
wells will approximate the cost of plugging and abandoning the wells. Benton
believes that the original cost of the equipment less the deductions computed
through 1994 year end for tax purposes represents a reasonable approximation of
the fair market value of the equipment to Benton. Benton also believes that
valuing the current assets and liabilities of the 1989-1 Partnership
(comprised of cash and intercompany payable) at their book value as of March 31,
1995 is appropriate to reflect the fair market value of these items, which are
expected to be collected and paid to Benton, to the extent outstanding, in the
stated amounts reflected in the 1989-1 Partnership's unaudited balance sheet
as of that date.

<PAGE>   71


         Proved Reserves. The calculation of the present value of the 1990-1
Partnership's Proved Reserves for the purpose of determining the Exchange Value
complies with the rules and regulations of the SEC relating to the calculation
of the present value of future net cash flows determined as of December 31, 1994
attributable to proved oil and gas reserves for disclosure and financial
reporting purposes. The regulations governing these reserves do not permit the
use of escalated prices and costs except in accordance with existing contractual
arrangements, and the resulting SEC PV 10 calculations may overestimate or
underestimate the actual future cash flows from the production and sale of oil
and gas and, consequently, the present value thereof.

         The gross quantities of Proved Reserves attributable to the 1990-1
Partnership's interest in its wells, together with the estimated present value
of those reserves, were estimated on an SEC PV 10 basis as of December 31, 1994
in a reserve report prepared by Benton and audited by Huddleston. A summary of
the report and a copy of the audit letter, setting forth the criteria and
assumptions used in evaluating the 1990-1 Partnership's Proved Reserves, are
included in Exhibit B.

         There are numerous uncertainties inherent in estimating quantities of
Proved Reserves. Huddleston audited the data and computations used by Benton's
petroleum engineer in their evaluation of the total Proved Reserves attributable
to all of the wells in which the 1990-1 Partnership had an interest as of
December 31, 1994. Estimates by other independent petroleum engineers could vary
from Benton's estimates and could result in higher or lower valuations.

         The estimates of the 1990-1 Partnership's future gross revenues
attributable to its estimated Proved Reserves as of December 31, 1994 were
calculated based on natural gas and crude oil prices in effect on that date.
Those prices had a weighted average of $1.63 per Mcf for natural gas and $15.94
per Bbl for oil.

         Future operating and development costs were based on the 1990-1
Partnership's operating and development costs as of December 31, 1994 and were
used without escalation. Future severance (production) and ad valorem (property)
taxes were calculated using rates prevailing at December 31, 1994. The estimated
future gross revenues, future operating and development costs and production
taxes were allocated to the 1990-1 Partnership in accordance with its interest
in oil and gas properties, taking into account applicable reversionary and
overriding royalty interests.

         The present values of the estimated net cash flows attributable to the
1990-1 Partnership's Proved Reserves of other properties were calculated by
discounting the future net cash flows to present value at the rate of 10% per
year, as prescribed by SEC regulations covering reserve reporting for financial
disclosure purposes. The discount factor is intended to reflect the timing of
future net cash flows. No further discount or risk adjustment was applied.
Present value, regardless of the discount rate used, is materially affected by
assumptions as to timing of future production, which may prove to have been
inaccurate.

         A summary of the reserve report for the 1990-1 Partnership and a copy
of the related audit letter are included in Exhibit B to this Prospectus.
Estimates of the 1990-1 Partnership's Proved Reserves and of the present value
of future net cash flows from the reserves are estimates only and are based on
numerous assumptions and conditions of these estimates.

         Other Assets and Liabilities. The tax-basis balances of the 1990-1
Partnership's equipment, excluding Umbrella Point Field equipment, aggregated
$13,037 at December 31, 1994, and the net book value of its current assets and
liabilities as of March 31, 1995 reflect a balance of $143,839 after 


                                       58
<PAGE>   72

deducting 1994 distributions aggregating $93,667. The equipment value and
current net assets are based upon the 1990-1 Partnership's 1994 year-end tax
accounting records and March 31, 1995 unaudited financial statements,
respectively, maintained in accordance with the applicable provisions of the
1990-1 Partnership Agreement.

         Benton believes that valuing the 1990-1 Partnership's equipment
(comprised of oil and gas production and transportation facilities) at its tax-
basis balances is favorable to the sellers of the producing properties since
many purchasers in transactions evaluated by Benton, as part of its on-going
involvement in the production area, allocate nominal value to well equipment on
the theory that its salvage value at the end of the commercial lives of acquired
wells will approximate the cost of plugging and abandoning the wells. Benton
believes that the original cost of the equipment less the deductions computed
through 1994 year end for tax purposes represents a reasonable approximation of
the fair market value of the equipment to Benton. Benton also believes that
valuing the current assets and liabilities of the 1990-1 Partnership
(comprised of cash and intercompany receivable) at their book value as of March
31, 1995 is appropriate to reflect the fair market value of these items, which
are expected to be collected and paid to Benton, to the extent outstanding, in
the stated amounts reflected in the 1990-1 Partnership's unaudited balance
sheet as of that date.

         General Intangibles. In determining the value attributed to General
Intangibles, Benton evaluated the success to date of the 1990-1 Partnership,
total consideration paid to date to the participants and the value to Benton of
dissolving and liquidation the 1990-1 Partnership so that Benton can focus on
its current operations and reduce the administrative burdens associated with
operating the Partnership. From inception through July 1995, the 1990-1
Partnership has made cash distributions to participants aggregating $2,452,364,
or $1,728 per 1990-1 Unit. Benton acknowledges the concerns raised by the
Investors in the 1990-1 Partnership with regard to operations of the
Partnership, the lack of success and thus the disappointing returns on
investment by the Investors. Because many of the Investors are or were
stockholders of Benton, Benton desires to maintain a good relationship with
these stockholders, many of whom have been strong supporters of Benton from
inception, and Benton desires to avoid future claims against it by participants
relating to the management of the Partnership. See "The Exchange Offer and
Proposal--Litigation and Related Matters." Assuming that the Investor in the
1990-1 Partnership elects to hold his or her shares of Common Stock and
exercises his or her Warrants at the end of the three-year term, and the market
price of the Common Stock is at or above approximately $19.50 per share, Benton
believes that the Investors in the 1990-1 Partnership, will have received
consideration in the form of cash distributions, Common Stock and Warrants in
excess of the initial investment in the 1990-1 Partnership, without regard to
any tax benefits received by the participants. The value of the General
Intangibles of the Partnership is not subject to valuation by third parties
since the General Intangibles do not represent actual assets of the Partnership.
Benton believes that the participants in the Partnership will not receive any
value for the General Intangibles in any alternative to the Exchange.

         Subsequent Adjustments. The Exchange Values will not be adjusted to
reflect changes after December 31, 1994 in the present value of the estimated
future net cash flows attributable to the 1990-1 Partnership's Proved
Reserves. No adjustments will be made to the Exchange Values on account of
changes in demand for or costs or prices of oil and gas that differ from the
assumptions employed or other market related events after December 31, 1994,
although those could affect the value of the 1990-1 Units.

         Proved Reserves. The calculation of the present value of the 1991-1
Partnership's Proved Reserves of other properties for the purpose of determining
the Exchange Value complies with the rules and regulations of the SEC relating
to the calculation of the present value of future net cash flows determined as
of December 31, 1994 attributable to proved oil and gas reserves for disclosure
and financial reporting purposes. The regulations governing these reserves do
not permit the use of escalated prices and costs except in accordance with
existing contractual arrangements, and the resulting SEC PV 10 calculations may
overestimate or underestimate the actual future cash flows from the production
and sale of oil and gas and, consequently, the present value thereof.

         The gross quantities of Proved Reserves attributable to the 1991-1
Partnership's interest in its wells, together with the estimated present value
of those reserves, were estimated on an SEC PV 10 basis as of December 31, 1994
in a reserve report prepared by Benton and audited by Huddleston. A summary of
the report and a copy of the audit letter, setting forth the criteria and
assumptions used in evaluating the 1991-1 Partnership's Proved Reserves, are
included in Exhibit B.

         There are numerous uncertainties inherent in estimating quantities of
Proved Reserves. Huddleston audited the data and computations used by Benton's
petroleum engineer in their evaluation of the total Proved Reserves attributable
to all of the wells in which the 1991-1 Partnership had an interest as of
December 31, 1994. Estimates by other independent petroleum engineers could vary
from Benton's estimates and could result in higher or lower valuations.

         The estimates of the 1991-1 Partnership's future gross revenues
attributable to its estimated Proved Reserves as of December 31, 1994 were
calculated based on natural gas and crude oil prices in effect on that date.
Those prices had a weighted average of $1.63 per Mcf for natural gas and $15.94
per Bbl for oil.

         Future operating and development costs were based on the 1991-1
Partnership's operating and development costs as of December 31, 1994 and were
used without escalation. Future severance (production) and ad valorem (property)
taxes were calculated using rates prevailing at December 31, 1994. The estimated
future gross revenues, future operating and development costs and production
taxes were allocated to the 1991-1 Partnership in accordance with its interest
in oil and gas properties, taking into account applicable reversionary and
overriding royalty interests.

<PAGE>   74

         The present values of the estimated net cash flows attributable to the
1991-1 Partnership's Proved Reserves were calculated by discounting the future
net cash flows to present value at the rate of 10% per year, as prescribed by
SEC regulations covering reserve reporting for financial disclosure purposes.
The discount factor is intended to reflect the timing of future net cash flows.
No further discount or risk adjustment was applied. Present value, regardless of
the discount rate used, is materially affected by assumptions as to timing of
future production, which may prove to have been inaccurate.

         A summary of the reserve report for the 1991-1 Partnership and a copy
of the related audit letter are included in Exhibit B to this Prospectus.
Estimates of the 1991-1 Partnership's Proved Reserves and of the present value
of future net cash flows from the reserves are estimates only and are based on
numerous assumptions and conditions of these estimates.

         Other Assets and Liabilities. The tax-basis balances of the 1991-1
Partnership's equipment, excluding the Umbrella Point field equipment,
aggregated $2,555 at December 31, 1994, and the net book value of its current
assets and liabilities as of March 31, 1995 reflect a balance of $81,359 after
deducting 1994 distributions aggregating $84,545. The equipment value and
current net assets are based upon the 1991-1 Partnership's 1994 year-end tax
accounting records and March 31, 1995 unaudited financial statements,
respectively, maintained in accordance with the applicable provisions of the
1991-1 Partnership Agreement.

         Benton believes that valuing the 1991-1 Partnership's equipment
(comprised of oil and gas production and transportation facilities) at its tax-
basis balances is favorable to the sellers of the producing properties since
many purchasers in transactions evaluated by Benton, as part of its on-going
involvement in the production area, allocate nominal value to well equipment on
the theory that its salvage value at the end of the commercial lives of acquired
wells will approximate the cost of plugging and abandoning the wells. Benton
believes that the original cost of the equipment less the deductions computed
through 1994 year end for tax purposes represents a reasonable approximation of
the fair market value of the equipment to Benton. Benton also believes that
valuing the current assets and liabilities of the 1991-1 Partnership
(comprised of cash and intercompany receivable) at their book value as of March
31, 1995 is appropriate to reflect the fair market value of these items, which
are expected to be collected and paid to Benton, to the extent outstanding, in
the stated amounts reflected in the 1991-1 Partnership's unaudited balance
sheet as of that date.

         General Intangibles. In determining the value attributed to General
Intangibles, Benton evaluated the success to date of the 1991-1 Partnership,
total consideration paid to date to the participants and the value to Benton of
dissolving and liquidation the 1991-1 Partnership so that Benton can focus on
its current operations and reduce the administrative burdens associated with
operating the Partnership. From inception through July 1995, the 1991-1
Partnership has made cash distributions to participants aggregating $338,182, or
$1,200 per 1991-1 Unit. Benton acknowledges the concerns raised by the
Investors in the 1991-1 Partnership with regard to operations of the
Partnership, the lack of success and thus the disappointing returns on
investment by the Investors. Because many of the Investors are or were
stockholders of Benton, Benton desires to maintain a good relationship with
these stockholders, many of whom have been strong supporters of Benton from
inception, and Benton desires to avoid future claims against it by participants
relating to the management of the Partnership. See "The Exchange Offer and
Proposal--Litigation and Related Matters." Assuming that the Investor in the
1991-1 Partnership elects to hold his or her shares of Common Stock and
exercises his or her Warrants at the end of the three-year term, and the market
price of the Common Stock is at or above approximately $19.50 per share, Benton
believes that the Investors in the 1991-1 Partnership, will have received
consideration in the form of cash distributions, Common Stock and Warrants in
excess of the initial investment in the 1991-1 Partnership, 


                                       61
<PAGE>   75

without regard to any tax benefits received by the participants. The value of
the General Intangibles of the Partnership is not subject to valuation by third
parties since the General Intangibles do not represent actual assets of the
Partnership. Benton believes that the participants in the Partnership will not
receive any value for the General Intangibles in any alternative to the
Exchange.

         Subsequent Adjustments. The Exchange Values will not be adjusted to
reflect changes after December 31, 1994 in the present value of the estimated
future net cash flows attributable to the 1991-1 Partnership's Proved
Reserves. No adjustments will be made to the Exchange Values on account of
changes in demand for or costs or prices of oil and gas that differ from the
assumptions employed or other market related events after December 31, 1994,
although those could affect the value of the 1991-1 Units.


                         REASONS FOR THE EXCHANGE OFFER

RECOMMENDATION OF THE MANAGING GENERAL PARTNER

         As Managing General Partner, Benton initiated and has proposed the
Exchange Offer and has recommended the approval of the Proposals. Benton's
decision is based on its conclusion that the Exchange will be more beneficial to
Investors than the alternatives of continuing the Partnerships or liquidating
all of the assets of the Partnerships and that the terms of the Exchange Offer
and related Proposals, including the method used to determine the Exchange
Values and the procedures involved in the Proposals, are both fair and
appropriate.

         The Managing General Partner, in reaching its conclusion to recommend
that each of the Investors accept the Exchange Offer and approve the Proposals,
considered a number of factors, including, without limitation, the following:

         (a)       The consideration to be received by each of the Partnerships
represents a premium over the standardized measure of discounted net cash flows
relating to each of the Partnership's proved reserves at December 31, 1994.

         (b)       The financial condition, results of operations and cash flows
of Benton and each of the Partnerships, both on a historical and a prospective
basis. In this regard, the Managing General Partner believes that Benton
historically, and on a pro forma basis after acquisition of the Partnerships'
assets, has been and is likely to continue in the future to be a strong company,
with prospects that could continue to show significant increases in results of
operations and cash flow.

         (c)       The consideration to be received by each of the Partnership's
Investors in connection with the Exchange Offer, and the distributions to the
Investors in liquidation, represents a significantly higher distribution to the
Investors than could be expected from continued total cash distributions.
Specifically, the Managing General Partner estimates that cash distributions for
the life of the respective Partnerships, if such Partnerships were to continue
operations, would be $358, $332 and $184 per Unit for the 1989-1 Partnership,
the 1990-1 Partnership and the 1991-1 Partnership, respectively.

         (d)       Current market conditions and historical market prices,
volatility and trading information with respect to the Common Stock of Benton,
compared to the lack of a trading market for the Partnership Units. In this
regard, the Managing General Partner considered the potential growth rate and
market price to earnings potential of Benton. The Managing General Partner
believes that the Investors will receive the benefit of any future growth in the
value of their equity interest in Benton rather than 


                                       62
<PAGE>   76

receiving cash distributions from the Partnerships, which are likely to decrease
rapidly as the remaining oil and natural gas reserves of the Partnerships are
depleted.

         (e)       Distributions to the Investors now allow for distributions
undiminished by ongoing Partnership plugging costs, which the Managing General
Partner estimates through the life of the Partnership to be $247, $160 and $56
per Unit for the 1989-1 Partnership, the 1990-1 Partnership and the 1991-1
Partnership, respectively.

         (f)       Liquidity of the Common Stock of Benton compared to the lack
of liquidity of the Partnership Units. The Common Stock of Benton has an active
trading market on NASDAQ-NMS. However, the Warrants that will be received in
the Exchange Offer do not currently have a public trading market. The
Partnership Units have no liquidity, and the Partnership Agreement restricts
transfer of the Partnership Units.

         (g)       The terms and conditions of the Exchange Offer, including the
amount of consideration to be paid the Investors and the form of the
consideration, the parties' representations, warranties, covenants and
agreements, and the conditions to their respective obligations set forth in the
Exchange Offer. The Managing General Partner deemed that the Exchange Offer is
favorable to each of the Partnerships' Investors. In reaching this conclusion,
the Managing General Partner noted the nature of the representations and
warranties and the limited number of conditions in the Exchange Offer. The
Managing General Partner believes that in the absence of extraordinary or
unforeseen circumstances, there is a high likelihood that the transaction will
be completed, subject to the requisite approval of the Partnerships' Investors.
Accordingly, the Managing General Partner believes that the Exchange Offer is
more favorable to each of the Investors than purchase and sale agreements that
are customarily entered into.

         (h)       The review of other alternatives for the Partnerships,
including possible sales of Partnership assets to third parties, continued
operation of the Partnerships and liquidation of the Partnerships. The Managing
General Partner did not believe that the sale of all of the assets of any of the
Partnerships were as attractive to the Partnerships as the Exchange Offer
because of the premium over the value of the reserves being offered by Benton in
the Exchange Offer, the uncertainty that a third party purchaser could be found
for all of the assets, and if found, whether a purchase and sale agreement could
be negotiated on terms favorable to the Partnerships. The only third party offer
received by the Managing General Partner which resulted in an agreement for
purchase of a substantial portion of the Partnerships' properties was the cash
offer from Goldking, described herein. If the Goldking sale is consummated, an
Investor may elect to receive cash in lieu of the Common Stock he would receive
in the Exchange Offer, if such election is made on the Letter of Transmittal to
be used in accepting the Exchange Offer. The Managing General Partner did not
believe that the continued operation of the Partnerships was as attractive to
the Partnerships as the Exchange Offer because the Managing General Partner
believes that the continued cash distributions made by the Partnerships are
likely to decrease rapidly as the remaining oil and natural gas reserves are
depleted. The Managing General Partner did not believe that liquidation of the
Partnership was as attractive to the Partnerships as the Exchange Offer because
the estimated liquidation values of the Partnerships are substantially less than
the consideration to be received by each of the Investors under the Exchange
Offer.

         (i)       The uncertainties and risks in the oil and gas industry and
the possibility that changes in the industry or continued volatility of oil and
gas prices could have a significantly greater effect on the Partnerships due to
the size of the Partnerships compared to Benton and the greater diversification
of oil 


                                       63
<PAGE>   77

and gas properties and prospects of Benton. The Managing General Partner also
considered the possibility that such uncertainties could be disadvantages to
Benton and advantages to the Partnerships.

         (j)       Benton is restricted under certain credit agreements from
paying cash dividends to its stockholders and the Investors could continue to
receive cash distributions from the Partnership. However, the Managing General
Partner believes that the cash distributions to the Investors from each of the
Partnerships will likely decrease rapidly as the remaining oil and natural gas
reserves are depleted.

         (k)       The tax consequences to the Partners in connection with the 
Exchange Offer and liquidation of the Partnerships.

         (l)       The Managing General Partner also considered the concerns
expressed by the many Investors in the Partnerships regarding the historical
performance and continued operation of each of the Partnerships and their
respective properties, including the litigation instituted by certain of the
Investors.

         In view of the wide variety of factors considered in connection with
its evaluation of the terms of the Exchange, the Managing General Partner did
not find it practicable to, and did not, quantify or otherwise attempt to assign
relative weights to the specific factors considered in reaching its
determination.

         THE MANAGING GENERAL PARTNER OF EACH OF THE PARTNERSHIPS HAS DETERMINED
THAT THE EXCHANGE IS FAIR AND IS IN THE BEST INTERESTS OF THE PARTNERSHIPS AND
THEIR RESPECTIVE PARTNERS AND HAS RECOMMENDED THAT THE PARTNERS OF EACH OF THE
PARTNERSHIPS TENDER THEIR PARTNERSHIP UNITS AND CONSENT TO THE PARTNERSHIP
PROPOSALS. THE EXCHANGE OFFER IS NOT CONDITIONED UPON ACCEPTANCE AND APPROVAL BY
ALL OF THE PARTNERSHIPS AND THE MANAGING GENERAL PARTNER BELIEVES THAT THE OFFER
IS FAIR TO ALL INVESTORS, REGARDLESS OF WHICH OR THE NUMBER OF PARTNERSHIPS
WHICH ACCEPT THE EXCHANGE OFFER FOR THE REASONS SET FORTH ABOVE.

ALTERNATIVES TO THE EXCHANGE

         The Managing General Partner's analysis of the most probable results of
continuing the Partnerships indicate that, while continuing the Partnerships
would avoid the risks associated with the ownership of Common Stock in Benton,
Investors will receive potentially greater values by participating in the
Exchange than the values they would derive from this alternative. Benton
estimates that continuing the 1989-1 Partnership under market and operating
conditions prevailing in 1994 would likely generate decreasing annual
distributions of $114 per 1989-1 Unit in 1995, $146 in 1996, $91 in 1997 and $7
in 1998. Benton estimates that the remaining economic life of the 1989-1
Partnership is 3.5 years. Benton estimates that continuing the 1990-1
Partnership under market and operating conditions prevailing in 1994 would
likely generate decreasing annual distributions of $97 per 1990-1 Unit in 1995,
$119 in 1996, $76 in 1997 and $30 in 1998. Benton estimates that the remaining
economic life of the 1990-1 Partnership is 5.5 years. Benton estimates that
continuing the 1991-1 Partnership under market and operating conditions
prevailing in 1994 would likely generate decreasing annual distributions of $61
per 1991-1 Unit in 1995, $83 in 1996, $40 in 1997 and $0 in 1998. Benton
estimates that the remaining economic life of the 1991-1 Partnership is 2.5
years.

         The Managing General Partner also believes that, while liquidating the
Partnerships would provide an immediate cash return and avoid the risks
associated with owning Benton Common Stock, the Exchange will provide Investors
with greater values than they would likely receive in liquidation of the

                                       64
<PAGE>   78

Partnerships. Benton's liquidation analysis reflects an estimated liquidation
value of approximately $324,663, $1,145,428 and $266,639 of the 1989-1
Partnership, the 1990-1 Partnership and the 1991-1 Partnership,
respectively, or $1,152, $807 and $946 per 1989-1 Unit, 1990-1 Unit and 1991-1
Unit, respectively. Benton received an independent offer to purchase each of
the Partnership's interest in the Umbrella Point Field (which represents 115.4%,
102.3% and 102.3% of the total Proved Reserves of the 1989-1 Partnership, the
1990-1 Partnership and the 1991-1 Partnership, respectively) for an
estimated total purchase price in cash of $1,672,512 as of March 31, 1995,
subject to adjustments. This estimated purchase price would represent potential
cash distributions to the Investors equal to $1,333, $762 and $764 per 1989-1
Unit, 1990-1 Unit and 1991-1 Unit, respectively. Benton's liquidation
analysis is based on the anticipated proceeds from the sale of the Umbrella
Point Field to Goldking, plus working capital for the Partnership at March 31,
1995, less estimated general and administrative costs involved in liquidation of
the Partnership. For purposes of determining the general and administrative
costs to the Partnership, Benton estimated that general and administrative
expenses would approximate the general and administrative expenses incurred by
the Partnership during the year ended December 31, 1994.

         The following tables summarize the results of Benton's liquidation
analysis in comparison to the Exchange Values for the Partnership Units
determined by Benton. The table also includes valuation data derived from
Benton's analysis of continuing the Partnerships. Benton did not undertake its
continuation analysis for the purpose of valuing the Partnerships, but solely to
illustrate the likelihood of decreasing distributions based on oil and gas
prices at December 31, 1994. However, because SEC disclosure standards for roll
up transactions require a comparison of the value of the consideration offered
in the transaction with the value of the consideration estimated for each
alternative to the transaction, the tables also reflect the results of extending
Benton's continuation analysis for the balance of the estimated life of the
Partnerships' Proved Reserves, and discounting the projected stream of
distributions to present value at the same 10% discount rate used in Benton's
liquidation analysis to account for the timing of cash flows as well as
production and concentration risks.

(1) The Exchange Value and liquidation value attribute no value to Managing
    General Partners' interests. The continuation analysis assumes continued
    distributions to the Managing General Partner pursuant to the terms of the
    Partnership Agreement.

(2) The assumed natural gas and oil prices are the prices used for preparation
    of the Partnership's reserve report at December 31, 1994. The continuation
    analysis was calculated based upon Benton's estimate of the remaining
    economic life of the Partnership, estimated to be 2.5 years.

         The actual amount that Investors would receive if the Partnerships
continued their respective operations would depend on production levels, which
cannot be predicted with certainty. In addition, the actual amount that
Investors would receive under either of the alternatives to the Exchange would
depend on future oil and gas prices. To the extent that future prices for those
commodities are materially higher or lower than the pricing assumptions made by
the Managing General Partner, those fluctuations would likely have a similar
effect on the operating results, distribution rates and market value of the
Partnership Units, largely negating the effect of price changes on a comparison
between the Exchange and either alternative of continuing the Partnerships or
liquidating their assets. In addition, Benton believes that liquidating the
Partnerships would deprive Investors of the opportunity to benefit from any
future upturn in oil and gas prices.

BENEFITS OF CONTINUED OPERATIONS

         The 1989-1 Partnership. Continuing to operate the 1989-1
Partnership could benefit the Investors by avoiding many of the risks associated
with owning Benton Common Stock. In addition, Benton does not pay cash dividends
on its shares of Common Stock and does not anticipate paying dividends in the
foreseeable future. However, Benton's continuation analysis reflects a present
value that is $322 per 1989-1 Unit, or $970 per 1989-1 Unit below the Exchange
Value. Accordingly, Benton believes that Investors are likely to receive less
value if the 1989-1 Partnership continues in its present form than they would
receive by participating in the Exchange. While this conclusion is supported by
Benton's analysis of continuing the 1989-1 Partnership, there can be no
assurance that the Exchange will be more beneficial to Investors than continuing
the 1989-1 Partnership.

         In determining that the 1989-1 Partnership had reached the stage in
its production history when consideration of the Exchange Offer became
appropriate, the Managing General Partner evaluated the anticipated results of
continuing the 1989-1 Partnership.

         The Managing General Partners' continuation analysis for the 1989-1
Partnership is based upon the Partnership's reserve report at December 31, 1994,
prepared by the Managing General Partner and audited by Huddleston. The
continuation analysis assumes revenues, taxes and expenses will be allocated to
participants and the Managing General Partners in the percentages set forth in
the 1989-1 Partnership Agreement. Based upon these assumptions, and further
discounted at 10%, the cash flow to the participants for the years indicated are
as follows:

BENEFITS OF LIQUIDATION

         The 1989-1 Partnership. If the 1989-1 Partnership liquidated its
assets and completed a dissolution upon the sale of its assets for cash, the
Investors would benefit by receiving an immediate cash return without continuing
to be subject to the risks of owning Benton Common Stock and risks of
participation in oil and gas operations. In addition, if the 1989-1
Partnership were liquidated in a cash transaction, the Investors could reinvest
the proceeds in similar or different investments. For the reasons described
below, however, Benton believes that liquidating the 1989-1 Partnership would
not provide Investors with greater values than those they would receive in the
Exchange. Although Benton made 


                                       70
<PAGE>   84

various assumptions that it believes to be reasonable in conducting the
liquidation analysis supporting this conclusion, there can be no assurance that
those assumptions would ultimately prove to be correct and that proceeds of a
cash sale would not exceed the value of the Common Stock and Warrants issuable
in the Exchange.

         Benton's decision to recommend the approval of the Proposal is
supported by its internal liquidation analysis, reflecting a liquidation value
of $324,663 or $1,152 per 1989-1 Unit. It is further supported by an
independent offer to purchase the 1989-1 Partnership's interest in the
Umbrella Point Field (which represents 115.4% of the total Proved Reserves of
the 1989-1 Partnership) for a total purchase price in cash of $375,643. This
purchase price would represent cash distributions to the Investors, following
satisfaction of current liabilities, equal to $1,276 per 1989-1 Unit. Based on
these factors, Benton has concluded that, while an asset sale in liquidation of
the 1989-1 Partnership might result in limited third-party interest in the
1989-1 Partnership's most significant asset, and a sale of the Partnership's
properties as a whole would provide an immediate cash return to Investors, it
would likely result in valuations by an unaffiliated bidder below the Total
Exchange Value, and further, any cash received would likely be equal to or less
than the liquidation value after payment of transaction costs and costs
associated with liquidation and dissolution, if another third party was willing
to purchase only the assets of the 1989-1 Partnership. Benton has not
conditioned this Exchange Offer on approval by the other Partnerships described
herein, but believes that a third party would significantly discount the value
of the Partnership's properties if it could not purchase the working interests
owned by all three Partnerships. Additionally, Benton has assumed sale
responsibility for payment of all transaction costs associated with the Exchange
Offer, allowing distribution of consideration without deduction for such costs.
Benton believes it unlikely that a third party would offer to purchase the
Partnership's assets, and also assume responsibility for payment of transaction
costs.

         (1)      At March 31, 1995, the 1989-1 Partnership had current assets,

                  $25,933, resulting in a working capital deficit of $15,980,

                  was determined based upon the actual expenses incurred by the
                  1989-1 Partnership for general and administrative expense for
                  the year ended December 31, 1994.

         (3)      Obtained by dividing the net aggregate liquidation value by
                  281.8182 Partnership Units. No liquidation value has been
                  attributed to the Managing General Partners' interest.

         Benton's liquidation analysis assumed that a Majority in Interest of
the Investors would approve the sale of all or substantially all of the 1989-1
Partnership's assets, as required under the 1989-1 Partnership Agreement.
Based on this analysis, the Managing General Partner concluded that Investors
would benefit more from the Exchange than a potential liquidation of the 1989-1
Partnership.

         The 1990-1 Partnership. If the 1990-1 Partnership liquidated its
assets and completed a dissolution upon the sale of its assets for cash, the
Investors would benefit by receiving an immediate cash return without continuing
to be subject to the risks of owning Benton Common Stock and risks of
participation in oil and gas operations. In addition, if the 1990-1
Partnership were liquidated in a cash transaction, the Investors could reinvest
the proceeds in similar or different investments. For the reasons described
below, however, Benton believes that liquidating the 1990-1 Partnership would
not provide Investors with greater values than those they would receive in the
Exchange. Although Benton made various assumptions that it believes to be
reasonable in conducting the liquidation analysis supporting this conclusion,
there can be no assurance that those assumptions would ultimately prove to be
correct and that proceeds of a cash sale would not exceed the value of the
Common Stock and Warrants issuable in the Exchange.

         Benton's decision to recommend the approval of the Proposal is
supported by its internal liquidation analysis, reflecting a liquidation value
of $1,145,428 or $807 per 1990-1 Unit. It is further 


                                       72
<PAGE>   86

supported by an independent offer to purchase the 1990-1 Partnership's
interest in the Umbrella Point Field (which represents 102.3% of the total
Proved Reserves of the 1990-1 Partnership) for an estimated total purchase
price in cash of $1,081,589. This purchase price would represent cash
distributions to the Investors equal to $762 per 1990-1 Unit. Based on these
factors, Benton has concluded that, while an asset sale in liquidation of the
1990-1 Partnership might result in limited third-party interest in the 1990-1
Partnership's most significant asset, a sale of the Partnership's properties
as a whole would provide an immediate cash return to Investors but would likely
result in valuations by an unaffiliated bidder below the total Exchange Value,
and further, any cash received would likely be equal to or less than the
liquidation value after payment of transaction costs and costs associated with
liquidation and dissolution. Benton has not conditioned this Exchange Offer on
approval by the other Partnerships described herein, but believes that a third
party would significantly discount the value of the Partnership's properties if
it could not purchase the working interests owned by all three Partnerships.
Additionally, Benton has assumed sale responsibility for payment of all
transaction costs associated with the Exchange Offer, allowing distribution of
consideration without deduction for such costs. Benton believes it unlikely that
a third party would offer to purchase the Partnership's assets, and also assume
responsibility for payment of transaction costs.

         (1)      At March 31, 1995, the 1990-1 Partnership had current assets,
                  less property held for sale, of $143,839 and liabilities of
                  $0, resulting in a working capital balance of $143,839,
                  excluding the property held for sale.

         (2)      Estimated expenses to the Partnership in preparing the
                  Partnership financial statements, tax returns, investor tax
                  statements and similar administrative matters. This estimate
                  was determined based upon the actual expenses incurred by the
                  1990-1 Partnership for general and administrative expense for
                  the year ended December 31, 1994.

         (3)      Obtained by dividing the net aggregate liquidation value by
                  1,419.192 Partnership Units. No liquidation value has been
                  attributed to the Managing General Partners' interests.

         Material changes in Benton's liquidation analysis did not take into
account additional discount factors that an unaffiliated buyer might apply to
reflect the 1990-1 Partnership's concentration of production and value in one
major property or its lack of a majority working interest in its wells. In
addition, Benton did not attempt to quantify the potential impact of being able
to secure a single buyer for all of the 1990-1 Partnership's properties under
the circumstances where the only available purchaser limited its bid to the
1990-1 Partnership's most significant property interest and excluded less 
desirable properties.

         Benton's liquidation analysis assumed that a Majority in Interest of
the Investors would approve the sale of all or substantially all of the 1990-1
Partnership's assets, as required under the 1990-1 Partnership Agreement.
Based on this analysis, the Managing General Partner concluded that Investors
would benefit more from the Exchange than a potential liquidation of the 1990-
1 Partnership.

         The 1991-1 Partnership. If the 1991-1 Partnership liquidated its
assets and completed a dissolution upon the sale of its assets for cash, the
Investors would benefit by receiving an immediate cash return without continuing
to be subject to the risks of owning Benton Common Stock and risks of
participation in oil and gas operations. In addition, if the 1991-1
Partnership were liquidated in a cash transaction, the Investors could reinvest
the proceeds in similar or different investments. For the reasons described
below, however, Benton believes that liquidating the 1991-1 Partnership would
not provide 


                                       74

Investors with greater values than those they would receive in the Exchange.
Although Benton made various assumptions that it believes to be reasonable in
conducting the liquidation analysis supporting this conclusion, there can be no
assurance that those assumptions would ultimately prove to be correct and that
proceeds of a cash sale would not exceed the value of the Common Stock and
Warrants issuable in the Exchange.

         Benton's decision to recommend the approval of the Proposal is
supported by its internal liquidation analysis, reflecting a liquidation value
of $266,639 or $946 per 1991-1 Unit. It is further supported by an independent
offer to purchase the 1991-1 Partnership's interest in the Umbrella Point
Field (which represents 102.3% of the total Proved Reserves of the 1991-1
Partnership) for a total purchase price in cash of $215,280. This purchase price
would represent cash distributions to the Investors equal to $764 per 1991-1
Unit. Based on these factors, Benton has concluded that, while an assets sale in
liquidation of the 1991-1 Partnership might result in limited third-party
interest in the 1991-1 Partnership's most significant asset, a sale of the
Partnership's properties as a whole would provide an immediate cash return to
Investors but would likely result in valuations by an unaffiliated bidder below

LACK OF INDEPENDENT REPRESENTATIVE

         Benton did not engage an independent representative to negotiate the
terms of the Exchange Offer on behalf of the Investors, since Benton believed
that the Exchange Values for each of the Partnerships is in excess of the fair
value of the assets of the Partnerships. In addition, Benton did not want to
provide fees to a third party to negotiate the terms of the Exchange. As a
result, the Exchange


                                       76
<PAGE>   90

Values and other term of the Exchange Offer may not be as favorable as the terms
that an independent representative might have obtained.

BOARD OF DIRECTORS OF BENTON; BENTON'S REASONS FOR THE EXCHANGE

         At a meeting held on April 26, 1995, the Board of Directors of Benton
unanimously approved the Exchange Offer and the issuance of Benton Common Stock
and Warrants in connection with the Exchange. The Delaware Corporation Law does
not require that the Benton stockholders approve the Exchange Offer or the
issuance of Benton Common Stock or Warrants, and no such approval is being
sought.

         In reaching its conclusion to approve the Exchange Offer, the Board of
Directors of Benton determined that the purchase of the Partnership assets by
Benton is consistent with and in furtherance of the long-term business
strategy of Benton. In addition, the Board believes that the Exchange Offer
provides the Investors in the Partnerships, many of whom are Benton
stockholders, the opportunity to benefit from the continued growth of Benton and
consideration in excess of the liquidation value of each of the Partnerships.
The Board understands the significant risks associated with the oil and gas
industry and drilling for oil and natural gas, but acknowledges the concerns
raised by the Investors in the Partnerships with regard to the disappointing
returns on investment by the Investors. Because many of the Investors are also
stockholders of Benton, the Board believes it prudent to maintain a good
relationship with these stockholders, who have been strong supporters of Benton
from inception, and the consideration to be given under the Exchange Offer is
indicative of Benton's desire to address the concerns of its Investors and
stockholders. The Board of Directors believes that the Exchange Offer may serve
to resolve the issues and claims made by certain Investors in the Litigation and
may forestall any further litigation surrounding or arising from the
Partnerships. In addition, the Board believes that dissolution of the
Partnerships upon consummation of the Exchange and adoption of the Proposals by
each of the Partnerships will allow Benton to focus its resources on the core
assets and projects of Benton.

FIDUCIARY DUTIES OF BENTON

         General. Benton's fiduciary duties to the Investors include legal
responsibilities of loyalty, care and good faith. As Managing General Partner of
the Partnerships, Benton may not profit by any conduct or transaction in
contravention of its fiduciary obligations to the Investors. Rights of action by
or on behalf of the Investors for any breach of these duties are provided under
most state limited partnership or other laws. Under California law, which is the
choice of law provided in the Partnership Agreements, a limited partner may
bring action against a general partner, upon a showing of the breach of its
fiduciary duty, to recover his capital contribution or to seek an accounting and
dissolution of the partnership. While a general partner would have the burden of
dispelling all doubts concerning its conduct, simple negligence or an error in
judgment not amounting to a breach of fiduciary duty would constitute a defense
to the limited partner's actions under California law. Benton believes that it
has complied with its fiduciary duties in the management of each of the
Partnerships and in connection with the Exchange Offer.

         Remedies for Breach of Fiduciary Duties. Under California law, except
as described below, if a non-consenting Investor believes that adoption of the
Proposal or consummation of the Exchange would constitute a breach of the
General Partner's fiduciary duties, the Investor could institute legal action
against the General Partner to enjoin the Exchange or implementation of the
Amendments contemplated by the Proposal or to recover damages resulting from the
consummation of the Exchange. In appropriate 


                                       77
<PAGE>   91

circumstances, a limited partner may institute a class action against its
general partner on behalf of himself and the other similarly situated limited
partners or a derivative action against a general partner on behalf of the
partnership to recover damages for a breach of a general partner's fiduciary
duties. This is a developing area of the law, and Investors who have questions
concerning the General Partner's duties should consult with their own legal
counsel.

         Limitations on Investors' Remedies. The Partnership Agreements provide
that the General Partner and its affiliates will not be liable to the
Partnership or the Investors for errors of judgment or any acts or omissions
that do not constitute negligence or misconduct. In addition, the Partnership
Agreements provide generally that, to the extent permitted by law, the
Partnership will indemnify the General Partner and its affiliates providing
services on behalf of the Partnerships against judgments and amounts paid in
settlement, plus costs and expenses (including reasonable attorneys' fees and
expenses) actually and reasonably incurred, if the indemnitee acted in good
faith and in a manner reasonably believed to be in, or not opposed to, the best
interests of the Partnership. In the opinion of the SEC, indemnification for
liabilities arising under the Securities Act is against public policy and
therefore unenforceable.

ACCESS TO INVESTOR LIST AND PROGRAM RECORDS.

         Benton will provide free of charge to any Investor, upon written
request, a current alphabetized listing of all Investors' names and addresses of
the Investors in a Partnership in which the requesting Investor owns a
Partnership Unit. Investors are afforded this right under the Partnership
Agreement and federal and state law. Investors also have the right under the
Partnership Agreement to inspect the books and records of his Partnership at all
reasonable times.


                        FAILURE TO APPROVE THE PROPOSALS

         In the event that the Investors of any of the Partnerships fail to
approve the Proposal, as set forth in this Prospectus, the Exchange of
Partnership Units tendered pursuant to the Exchange offer will not be
consummated and the assets of that Partnership will not be transferred to
Benton. However, the assets of any Partnership whose Investors do approve the
Proposal and accept the Exchange will be transferred to Benton. In the event the
Investors of a Partnership fail to approve the Proposal, that Partnership would
continue in its business as heretofore operated. However, it is possible that a
new offer might be negotiated between such Partnership and Benton. No such other
terms have been discussed or agreed upon. In addition, the Managing General
Partner may also explore other alternatives, such as the sale of that
Partnership's assets to a third party. However, there is no assurance that the
Managing General Partner could find a third party interested in purchasing such
assets or that the terms and conditions of such a purchase and sale agreement
would be as favorable as the terms offered pursuant to the Exchange Offer.

         Pursuant to the terms of the purchase agreements with Goldking, the
seller or purchaser may terminate the agreement if the closing has not occurred
on or before December 31, 1995. If the Partnerships do not approve the
Proposals, there can be no assurance that a sale of the Partnerships' assets for
cash pursuant to the Goldking Agreement can be accomplished prior to such
termination date.

                               CONSENT PROCEDURES

WRITTEN CONSENT AND VOTE REQUIRED

         Investors may tender their Partnership Units or vote against the
Proposal by properly completing and executing the Letter(s) of Transmittal
accompanying this Prospectus and attached as Exhibit D in accordance with the
instructions contained therein, and delivering it, together with any requisite
supporting documents indicated in the Letter of Transmittal, prior to the
Expiration Date, to Benton at the following address:

                           Benton Oil and Gas Company
                           1145 Eugenia Place, Suite 200
                           Carpinteria, California 93013
                           Telephone: (805) 566-5600

         PARTNERSHIP UNITS WILL NOT BE VALIDLY TENDERED UNLESS THE LETTER OF
TRANSMITTAL HAS BEEN COMPLETELY AND FULLY EXECUTED IN ACCORDANCE WITH THE
INSTRUCTIONS THERETO AND ACCOMPANIED BY ALL OTHER REQUIRED DOCUMENTS IN FORM AND
SUBSTANCE SATISFACTORY TO BENTON. All questions concerning the validity, form
and eligibility (including time of receipt) of tenders will be determined by
Benton, whose determination will be final and binding.

CONSENT TABULATION

         All votes consenting to the Proposal and withholding consent, as
directed in the Letter of Transmittal submitted by Investors, will be tabulated
by First Interstate Bank. First Interstate Bank has agreed to make the
tabulation available to Investors upon request to Benton.

EXPIRATION OF EXCHANGE OFFER

         The Exchange Offer will be held open for 60 days from the date of this
Prospectus and will expire at 5:00 p.m. Pacific Time on the Expiration Date. The
Expiration Date will be ___________, 1995, unless extended by Benton for a 
period of up to 60 days. Notice of extension of the Exchange Offer, if made,
will be given by mail to each Investor. An extension will be effective upon
mailing of notice.

AMOUNT TENDERED

         Benton will not accept tenders of less than all of an Investor's
Partnership Units.

REVOCABILITY OF TENDERS

         Tenders of Partnership Units and consents to the Proposal may be
revoked at any time prior to the Expiration Date by sending notice of revocation
to Benton at 1145 Eugenia Place, Suite 200, Carpinteria, California 93013,
Attention: Toni L. Jackson. The notice should identify the Investor, indicate
the Partnership Units for which he is revoking his tender and indicate an
intention to revoke a prior tender and withhold consent to the Proposal. If this
Prospectus is amended to reflect a material adverse development, the Expiration
Date will be extended, if required, to afford at least 20 days for Investors to
revoke their prior tender of Partnership Units.

SOLICITATION OF LETTERS OF TRANSMITTAL

         Benton intends to enter into an agreement with participating NASD
broker/dealers ("Solicitating Dealer") to assist in the solicitation of Letters
of Transmittal for the Exchange Offer. Each Solicitating Dealer who executes an
agreement with Benton will be entitled to receive a fee from Benton equal to 2%
of the aggregate Exchange Value of Units held by Investors who return a
completed Letter of Transmittal (whether they vote for or against the Proposal)
as a result of its solicitation effort (or an aggregate for all Solicitating
Dealers of up to $70,179), as evidenced by the appearance of its name on the
Letter of Transmittal in the space provided for that purpose. Total fee and
expense reimbursements to the Solicitating Dealers will not exceed 2% of the
Total Exchange Value.

         Benton has agreed to indemnity Solicitating Dealers against certain
civil liabilities, including liabilities under the Securities Act. The
Solicitating Dealers may be deemed to be underwriters within the meaning of the
Securities Act.

         Holders of Units in the Partnerships who elect to accept the Exchange
Offer may elect to receive cash in lieu of shares of Common Stock to be issued,
BUT CASH WILL BE DISTRIBUTED TO HOLDERS MAKING SUCH ELECTION ONLY IF THE SALE OF
THE UMBRELLA POINT FIELD TO GOLDKING, AS DESCRIBED HEREIN, IS ACTUALLY
CONSUMMATED. A holder who wishes to accept the Exchange Offer and make an
election to receive cash in lieu of shares of Common Stock should properly
indicate such election on the Letter of Transmittal. If the sale of the Umbrella
Point Field working interests to Goldking in consummated, a holder who elects to
receive cash in lieu of Common Stock will receive $1,292 for each 1989-1 Unit,
$957 for each 1990-1 Unit and $1,146 for each 1991-1 Unit, with Warrants in the
amounts described herein. There can be no assurance from Benton that the sale of
the Umbrella Point Field to Goldking will be consummated, and therefore, an
Investor should make a decision to accept the Exchange Offer based solely upon a
decision to receive Common Stock and Warrants in the amounts set forth herein.

ACCEPTANCE OF TENDERS

         On the Closing Date, subject to the satisfaction or waiver of the
conditions to the Exchange Offer, Benton will accept all Partnership Units
properly tendered pursuant to the Exchange Offer. If the Partnerships accept the
Proposals, Benton will, on behalf of the approving Partnerships, cause the
assets of such Partnerships, subject to associated liabilities, to be withdrawn
from the Partnership and contributed to Benton, effective as of the Effective
Date, in exchange for the Common Stock and Warrants which will be issued and
delivered promptly after the Closing Date.

         On the Closing Date, Benton will cause certificates representing the
Common Stock and the Warrants issuable in the Exchange to be registered in the
name of the holders who have accepted the Exchange Offer. Benton will also cause
a certificate representing the shares of Common Stock and Warrants that will be
issued to participants upon liquidation of each of the Partnerships to be issued
in the name of the Partnership, pending dissolution, liquidation and winding-up
of the Partnerships. Immediately thereafter, Benton will cause the shares of
Common Stock and Warrants issued in the name of the Partnership to be
transferred into certificates representing Common Stock and Warrants, registered
in the names of the individual participants remaining in the Partnerships
following liquidation.

SPECIAL REQUIREMENTS FOR CERTAIN INVESTORS

         Some of the Investors are entities such as estates, trusts,
corporations, limited partnerships or general partnerships. With respect to a
Partnership Unit tendered by an Investor other than an individual, 


                                       80
<PAGE>   94

Benton may elect, at its option, to require that each Letter of Transmittal be
accompanied by evidence that the Investor has met all requirements of its
governing instruments, such as applicable partnership or joint venture
agreements, and is authorized to tender its Partnership Units under the laws of
the jurisdiction in which the entity was organized. With respect to most trusts,
including individual retirement accounts, Benton expects to require only that
the named trustee (or authorized representative thereof) execute the Letter of
Transmittal.

REPRESENTATIONS AND COVENANTS

         Each Investor represents in the Letter of Transmittal that he has, and
will have as of the Closing Date, the right and authority to transfer his
Partnership Unit, and that his Partnership Unit is free and clear of all liens,
encumbrances and adverse claims. The Letter of Transmittal also contains a
covenant by the Investor to execute any additional documents and instruments
that may be reasonably required to more effectively transfer to and to vest in
Benton the assets underlying the tendered Partnership Units and a power of
attorney to Benton to permit Benton, as Managing General Partner, to execute on
his behalf any additional documents necessary to consummate the Exchange,
including any documents on behalf of the Investors that may be necessary to
withdraw the assets of the Partnership and contribute those assets to Benton.

VALIDITY OF TENDERS

         All questions concerning the validity, form, eligibility (including
time of receipt) and acceptance of the Partnership Units tendered will be
determined by Benton, whose determination will be final and binding. The
interpretation by Benton of the terms and conditions of the Exchange Offer
(including the instructions to the Letter of Transmittal) will also be final and
binding. Benton reserves the right to waive any irregularities or conditions
regarding the manner of tender. Any irregularities in connection with such
tenders must be cured within such time as Benton determines unless waived by

                        CERTAIN FEDERAL TAX CONSEQUENCES

         The following tax discussion summarizes certain federal income tax
consequences of the Exchange. This summary reflects the advice of Emens, Kegler,
Brown, Hill & Ritter Co., L.P.A., counsel to Benton in connection with the
Exchange. It is intended to provide only a general summary and does not include
a complete analysis of the consequences that may vary with or are contingent
upon individual circumstances, such as a taxpayer who is subject to special
provisions of the Internal Revenue Code. This discussion does not address the
federal income tax treatment of other transactions related to the Exchange, any
aspect of state, local or foreign tax laws, or any federal laws other than those
pertaining to income tax.

         None of the parties have requested a ruling from the Internal Revenue
Service with respect to the federal income tax consequences of the Exchange. No
assurance can be given that future legislation, regulations, administrative
pronouncements or court decisions will not significantly change the law and
materially affect the conclusions expressed herein. Any such change, even though
made after the consummation of the Exchange, could be applied retroactively.

TAX CONSEQUENCES OF THE EXCHANGE

         Upon the exchange of the Partnership Units for Common Stock and
Warrants, Investors shall recognize gain equal to the amount by which the fair
market value of the Common Stock and Warrants received by them exceeds their
respective bases in the Partnership Units exchanged therefor. Similarly, those
Investors who do not participate in the Exchange, but rather receive Common
Stock and Warrants upon liquidation of the Partnerships, should be deemed to
have transferred their Partnership Units for Common Stock and Warrants.

         It is possible that the Internal Revenue Service may argue that the
transaction constitutes a transfer of assets of the Partnership to Benton for
Common Stock and Warrants with the Common Stock and Warrants then distributed to
the Investors in liquidation of their interests in the Partnerships. Under such
a characterization of the transactions, the Partnerships would recognize gain on
the disposition of the assets which would be allocated to the Investors. Such a
characterization could affect the amount of gain recognized by the Investor.
However, courts evaluating the transfer of all of the assets of a partnership
followed by a termination of the business of the partnership have generally held
that such transactions will be characterized as a transfer of partnership
interests in exchange for the assets received rather than a transfer by the
partnership of assets and subsequent liquidation. Therefore, the treatment
afforded Investors not consenting to the Exchange should not differ from the tax
treatment realized by Investors who agree to exchange their Partnership Units
for Common Stock and Warrants.

         Assuming the Investor has held his Interest for more than one year and
assuming his Interest has not been held for sale in the ordinary course of the
Investor's trade or business, any gain or loss realized upon the transfer of the
Partnership Units will be taxed as long term capital gain or loss, except to the
extent that the consideration received is attributable to his allocable share of
substantially appreciated inventory items and unrealized receivables (including
depreciation recapture and excess intangible drilling and development costs) of
the Partnerships. The portion of any gain attributable to these items will be
taxed to the Investor as ordinary income. In addition, in the event of a
recharacterization of the transaction as a transfer of assets, additional
ordinary income could be recognized by the Partnerships which would be allocable
to Investors.

<PAGE>   97

REALIZATION OF SUSPENDED PASSIVE LOSSES

         Upon disposition of the Partnership Units, the Investors will have
completely disposed of their Interest in the Partnerships. Any Investor who has
any suspended passive losses resulting from the ownership of Partnership Units
will realize those suspended passive losses upon consummation of the Exchange.

BASIS IN STOCK AND WARRANTS

         Upon consummation of the Exchange, the basis of the Investors in the
Common Stock and Warrants received by them shall be equal to the fair market
value of such securities as of the date of consummation of the Exchange.

         THE PRECEDING DISCUSSION IS INTENDED ONLY AS A SUMMARY OF CERTAIN
FEDERAL INCOME TAX CONSEQUENCES OF THE EXCHANGE AND DOES NOT PURPORT TO BE A
COMPLETE ANALYSIS OR DISCUSSION OF ALL POTENTIAL TAX EFFECTS RELEVANT THERETO.
THUS, INVESTORS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS AS TO THE SPECIFIC
TAX CONSEQUENCES TO THEM OF THE EXCHANGE, INCLUDING TAX RETURN REPORTING
REQUIREMENTS, THE APPLICABILITY AND EFFECT OF FEDERAL, STATE, LOCAL AND OTHER
APPLICABLE TAX LAWS AND THE EFFECT OF ANY PROPOSED CHANGES IN THE TAX LAWS.

The participants are given the option of accepting cash or shares of the
Company's common stock in exchange for their partnership units. The pro forma
balance sheet above assumes that the participants accept stock in exchange for
their partnership units. If the participants accept cash rather than shares,
cash would be reduced to $20,619,904 and $20,421,720 for the minimum and maximum
pro forma balance sheets, respectively. Common shares outstanding would be
reduced to 24,931,862, common stock would be reduced to $249,319 and additional
paid in capital would be reduced to $92,833,257 and $94,028,217 in the minimum
and maximum pro forma balance sheets, respectively.

The participants are given the option of accepting either cash or shares of the
Company's common stock in exchange for their partnership units. The pro-forma
statements of operations above assume that the participants accept stock in
exchange for their partnership units. If the participants accept cash rather
than shares, the weighted average number of shares would be 26,037,055 for both
the minimum and maximum pro-forma statements of operations.

             (e) Record roll-up expenses and payments associated with the
                 acquisition of partnership units. Included as roll-up expenses
                 and payments are the value of the warrants issued to the
                 participants and issuance and distribution expenses which will
                 be charged to paid in capital in connection with the issuance
                 of the securities.

The participants' are given the option of accepting either cash or shares of the
Company's common stock in exchange for their partnership units. The pro-forma
statements of operations above assume that the participants accept stock in
exchange for their partnership units. If the participants accept cash rather
than shares the weighted average number of shares would be 24,850,922 for both
the minimum and maximum pro forma statements of operations.

BUSINESS

         Benton Oil and Gas Company ("Benton" or the "Company") is primarily
engaged in the development and production of oil and gas properties. The
Company's operations are focused on the eastern region of Venezuela, the Gulf
Coast region of Louisiana and the West Siberia region of Russia. Benton's
business strategy is to seek new reserves in areas of low geologic risk and to
exploit underdeveloped existing oil and gas fields. The Company implements the
exploitation strategy through the in-house design and interpretation of 3-D
seismic surveys and through workovers, recompletions, redrilling and exploration
and development drilling.

         Internationally, the Company seeks projects with significant reserve
potential in areas with low geologic risk and known proved reserves where, in
certain situations, the Company can add value by employing modern exploration,
drilling, completion and production techniques. To reduce risk, control costs,
and facilitate local transactions, the Company has formed ventures with local
foreign partners.

<PAGE>   114

         Domestically, the Company integrates 3-D seismic technology with
subsurface geologic data from previously drilled wells. This geophysical
evaluation enables the Company to discover previously undetected reserves in
existing fields. The Company believes that it enjoys a competitive advantage in
finding and developing reserves on an economic basis because of its
concentration on 3-D seismic technology, the training and qualifications of
its in-house technical team and the practical experience and knowledge which
this team has acquired over past years. The Company's recognized technical
expertise has afforded it access to projects it otherwise would not have
enjoyed.

         In the ordinary course of its business, the Company continues to
evaluate acquisition, joint venture and other opportunities that would enable it
to further its business strategy.

(1)   All Venezuelan reserves are attributable to an operating service agreement
      between Benton-Vinccler and Lagoven, S.A. under which all mineral rights
      are owned by the Government of Venezuela.
(2)   The Company's engineering estimates, which have been prepared by the
      Company and audited by Huddleston & Co., Inc., independent petroleum
      engineers, indicate that approximately 18 Bcf of natural gas reserves (net
      to the Company's interest) will be developed and produced in association
      with the development and production of the Company's proved undeveloped
      oil reserves in Russia. The Company expects that, due to current market
      conditions, it will initially reinject or flare such associated natural
      gas production and, accordingly, no future net reserves have been assigned
      to these reserves. Under the joint venture agreement, such reserves are
      owned by the Company in the same proportion as all other hydrocarbons in
      the North Gubkinskoye Field, and subsequent changes in conditions could
      result in the assignment of value to these reserves.

VENEZUELA

         In July 1992, the Company and Vinccler, a Venezuelan construction and
engineering company, signed an operating service agreement with Lagoven, S.A.
("Lagoven"), an affiliate of the national oil company, PDVSA, to reactivate and
further develop the Uracoa, Bombal and Tucupita Fields (the "Fields"), which are
a part of the South Monagas Unit (the "Unit"). Of the 230 foreign companies
responding to Venezuela's initial call for indications of interest, the Company
was one of three foreign companies ultimately awarded an operating service
agreement to reactivate existing fields by PDVSA. The Company was the first U.S.
company since 1976 to be granted such an oil field development contract in
Venezuela.

         Under the terms of the operating service agreement, Benton-Vinccler,
the Company's 80% owned Venezuelan subsidiary, is a contractor for Lagoven and
is responsible for overall operations of



                                      101
<PAGE>   115
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. 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. During each quarter of 1994, the
adjusted maximum total fee was 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 a capital recovery fee.

         The Unit is in the southeastern part of the state of Monagas in eastern
Venezuela. The Unit is approximately 51 miles long, eight miles wide and
consists of 157,843 acres, of which the Fields comprise approximately one-
half. Benton-Vinccler intends to explore the remaining portions of the Unit
for possible development activities. At December 31, 1994, Proved Reserves
attributable to the Company's Venezuelan operations were 60.7 MMBOE, which
represented 75% of the Company's Proved Reserves, all of which were located in
the Uracoa and Bombal Fields. Benton-Vinccler has reactivated fifteen
previously drilled wells and completed 21 new wells using modern drilling and
completion techniques that have not previously been utilized on the Fields.
Benton-Vinccler also has installed specialized production facilities commonly
used in heavy oil production in the United States but not previously utilized
extensively in Venezuela to process crude oil of similar gravity or quality.
Benton-Vinccler commenced production during the second quarter of 1993. During
1994, average daily production steadily increased from 3,400 Bbl of oil during
the first quarter to 6,700 Bbl in the second quarter, 7,200 Bbl in the third
quarter and 10,200 Bbl in the fourth quarter. Currently, 36 wells are producing
approximately 14,000 Bbl of oil per day.

        Benton-Vinccler intends to completely develop the Uracoa Field by
drilling approximately 90 to 100 wells. It also plans to reactivate and
completely develop the Bombal Field by drilling approximately 25-30 wells and
to evaluate the potential of the Tucupita Field in 1996 by testing 3 wells.
During the first quarter of 1995, Benton-Vinccler shot 150 kilometers of
seismic and is currently interpreting the data. Following the initial
interpretations of such seismic, Benton-Vinccler may also 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. Budget and
development plans submitted by Benton-Vinccler have been approved by Lagoven in
the past and the Company believes that such approvals will be granted in the
future.

         In June 1994, the Venezuelan government, amid economic uncertainties
and bank crises, suspended certain constitutional rights and implemented certain
exchange and price controls. Currently, exchange and price controls remain in
place, with no indication of when such controls will be lifted. To date, neither
the current economic uncertainties nor the exchange and price controls have had
an adverse effect on the Company's operations in Venezuela. The Company has
applied for insurance to cover the risk of currency repatriation and
inconvertibility, expropriation and interference with operations for its


                                      102
<PAGE>   116

Venezuelan operations with OPIC, an agency of the United States government.
While OPIC has indicated that such insurance is available, there can be no
assurance that the Company will be able to obtain this insurance.

UNITED STATES

Louisiana

         The Company has successfully pursued acquisition and joint venture
opportunities in the United States which have become more readily available as
major oil and gas companies continue to consolidate operations and focus
exploration and development activities outside the United States. At December
31, 1994, Proved Reserves of the Company attributable to the United States were
2.9 MMBOE, which represented 4% of the Company's Proved Reserves. Substantially
all of the Company's domestic activities are located in the Louisiana Gulf Coast
at the West Cote Blanche Bay, Rabbit Island and Belle Isle Fields. The Company,
Texaco and Oryx are currently producing from and further developing 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 whereby Tenneco has 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.

         Several key elements common to the three fields include their discovery
and initial development prior to World War II, peak production periods occurring
prior to 1960, extremely complex geology, relatively little modern exploration
technology being applied, and long-term natural gas sales contracts at prices
below $0.30 per Mcf which discouraged any significant drilling and development
until the contracts expired in the last few years.

         The state leases relating to these fields were subject to litigation
between Texaco and the State of Louisiana. Although the Company was not a party
to this litigation, its interests in the three fields were subject to the
litigation. In February 1994, Texaco and the State entered into a Global
Settlement Agreement. As a result of this agreement, Texaco committed to certain
acreage development and drilling obligations which may affect the Company and
certain of its Louisiana properties. The Company believes that the settlement
should have no effect on its proved reserves and will have no material adverse
effect on the Company.

         West Cote Blanche Bay Field

         The West Cote Blanche Bay Field is located on 5,892 acres in a shallow
bay in St. Mary Parish, approximately 125 miles southwest of New Orleans with
water depths averaging seven to eight feet. The field was discovered in 1938 by
Texaco, which continues to operate the field. The Company believes that, at
approximately 3.5 miles long and two miles wide, the West Cote Blanche Bay Field
contains one of the largest salt domes in the Gulf Coast. More than 300 separate
oil and gas reservoirs have been identified by Texaco and the Company from a
total of approximately 680 wellbores in 180 different sandstone formations, at
depths from 1,700 to 13,000 feet. At December 31, 1994, the field had
cumulatively produced over 181 MMBbl of oil and 225 Bcf of natural gas.

         Since the Company's first acquisition of an interest in the West Cote
Blanche Bay Field, it has worked with Texaco in the technical evaluation of the
field. Until late 1994, the prospect evaluations covered all depths and included
the drilling wells and a substantial number of recompletions and replacement
wells in oil reservoirs at depths of 2,000 to 10,500 feet. As a result of
ongoing evaluation, in late 1994 the Company decided to focus almost exclusively
on exploitation of gas and oil reservoirs at depths below 10,000 feet, utilizing
the results of the 3-D seismic interpretations. To mitigate the risk of
concentrating on deeper, more expensive wells, the Company sold approximately
25% of its working interest to Tenneco. Also, in March 1995, the Company and its
affiliates and Tenneco sold their interests in the shallower oil depths (above
approximately 10,575 feet) to WRT Energy Corporation, another working interest
owner in the field.

         Rabbit Island Field

         Rabbit Island is located in state waters in Iberia and St. Mary
Parishes, approximately 95 miles southwest of New Orleans. The dome was
discovered in 1939 by Texaco which continues to operate the field. Compared to
West Cote Blanche Bay, on whose 5,892 acres more than 800 wells have been
drilled, just over 200 wells have been drilled on the 27,909 acres of the Rabbit
Island Field. Cumulative production through December 31, 1994 was 48 MMBbl of
oil and 1.2 Tcf of gas from 51 productive zones.

         In 1992, the Company signed an agreement with Texaco to fund and
conduct a 3-D seismic program covering approximately 105 square miles over the
Rabbit Island project area. The estimated cost to the Company of this program is
approximately $6.0 million, substantially all of which has been expended. The
seismic survey has been shot, processed and is currently being interpreted.

         Pursuant to the agreement, the Company may drill five wells over a
period of up to five years. As identified below, the first well has been
drilled. Assuming the remaining four wells are drilled in accordance with the
terms set forth in the agreement, the Company will earn a 50% working interest
in 

                                      104
<PAGE>   118
the entire field (other than among other things, wells previously drilled by
Texaco). The first well in the drilling program was successfully completed in
January 1995 and is currently producing approximately 9.5 MMcf of natural gas
per day. The Company expects to drill up to four additional wells during 1995 at
Rabbit Island at a cost of up to $4 million.

         Certain of the Company's rights and 50% of its interest in the Field
were sold to Tenneco in July 1993. In May, 1995, the Company and Tenneco signed
an agreement in principle with Texaco to expand the acreage under the Rabbit
Island Field agreement by 10,452 acres in exchange for an increase in the number
of earning wells to be drilled by the Company from 5 to 8 wells.

         Belle Isle Field

         The Belle Isle Field is located on the shore of the Atchafalaya Bay,
approximately 75 miles southwest of New Orleans, in St. Mary Parish. The field
was discovered in 1941 and developed by Sun Oil Company. Currently, 12,000 acres
on the north portion of the field are operated by Oryx, and 6,400 acres on the
south portion of the field are operated by Apache Corporation (previously
operated by Texaco). As of December 31, 1994, the Belle Isle Field had
cumulatively produced over 50 MMBbl of oil and 1 Tcf of natural gas.

         In 1990, the Company reached an agreement with Oryx to shoot a 3-D
seismic survey over its portion of the field. Pursuant to the agreement, upon
completing the survey and processing the seismic data, Oryx granted the Company
the right to participate in the drilling of wells on Oryx's portion of the field
and the Company will have a 33% working interest in any well so drilled from the
top of the deep sands known as the "Rob L Sands" (at a depth of 12,500 feet) and
below. Under the agreement, up to two exploratory wells and two development
wells may be drilled in any calendar year. In the event that Oryx decides to
solicit the participation of a third party in certain drilling operations above
the Rob L Sands, Oryx has granted the Company a right of first refusal to
participate in such drilling and receive a 33% working interest in the resulting
wells.

         In 1991, the Company reached an agreement with Texaco to evaluate 5,500
acres on the southern portion of the field by extending the 3-D seismic
survey. Pursuant to this agreement, upon the Company's completion of the seismic
survey and its drilling of an initial test well in accordance with the terms set
forth in the agreement, Texaco assigned to the Company a 50% working interest in
its entire 6,400 acre portion of the Belle Isle Field (other than, among other
things, existing wells previously drilled by Texaco).

         In 1992, the Company completed a 55.75 square mile 3-D seismic survey
over the Belle Isle Field, thereby satisfying the survey obligations that are
prerequisites for earning working interests in the Texaco portion of the Field
and the Oryx wells. The survey was reprocessed in 1993 and is being evaluated on
an ongoing basis. In 1993, the Company satisfied the drilling requirements under
the agreement with Texaco, thereby earning its 50% working interest on the
Texaco portion of the field.

         In October 1994, the Company completed the Belle Isle State Lease 340
No. 1 well. This well is currently producing at rates of approximately 6 MMcf of
natural gas per day. The Company has until September 1, 1997 to exercise its
right to participate in any future Oryx wells. If the Company has participated
in the drilling of a producing well by that time, the Company's right to
participate in future wells will continue. Certain of the Company's rights and
50% of its interest in the Field were sold to Tenneco in July 1993.


                                      105
<PAGE>   119
         In January 1995 Texaco sold its interest in Belle Isle to Apache
Corporation. The Company is unable at this time to assess the impact on the
development of the field as a result of this sale.

         Tenneco Agreements

         In June 1993, the Company entered into an agreement with Tenneco which
provided for payments to the Company of approximately $6.7 million in exchange
for a 50% interest in the Company's operations at the Rabbit Island and Belle
Isle Fields. The agreement also provided Tenneco with a five year option to
participate on a promoted basis as a 50% partner in any future ventures that the
Company acquired in the Gulf Coast area, except for the West Cote Blanche Bay
Field. The Company also has granted an option in favor of Tenneco to purchase,
at a market price, all of the Company's gas produced from the Gulf Coast.
Tenneco has exercised its option to purchase the Company's share of natural gas
production from all three fields.

         In November 1994, the Company sold to Tenneco a 10.8% working interest
(24.9% of the Company's 43.3% working interest) in the West Cote Blanche Bay
Field for approximately $5.8 million and future consideration of up to $3.7
million.

         WRT Agreement

         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.

OTHER PROPERTIES

         At December 31, 1994, the Company had proved reserves of 180 MBOE and 6
MBOE in the Umbrella Point Field in Texas and certain fields in Louisiana and
Mississippi, respectively. In July 1995, the Company sold its interest in the
Umbrella Point Field.

         Actual exploration and development activities in the United States
could ultimately vary from those currently projected by the Company, depending,
among other factors, on the availability of drilling rigs, the availability of
financing, the success of the activities and the continued concurrence of
working interest partners as to the timing and extent of such activities.

RUSSIA

         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. The Company's partners are the official exploration and
production bodies which have been discovering and operating fields in the region
covered by the joint venture for many years, and which have access to pipelines,
railroads and other vital infrastructure. GEOILBENT develops, produces and
markets oil and condensate from the North Gubkinskoye Field in the West Siberia
region of Russia, 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 zones) and is
surrounded by large proven fields. Before commencement of GEOILBENT's
operations, North Gubkinskoye was one of the largest non-producing fields in
the region. At December 31, 1994, the Proved Reserves attributable to the North
Gubkinskoye Field were 17.5 MMBOE, which represented 22% of the Company's Proved
Reserves.


                                      106
<PAGE>   120
         During the third quarter of 1992, GEOILBENT commenced initial
operations which included the construction of a 37 mile oil pipeline and
installation of temporary production facilities. Completed in April 1993, with a
design capacity of 75,000 Bbl of oil per day, the pipeline transports oil from
the North Gubkinskoye Field south to the main Russian oil pipeline network. The
venture has been exporting oil since the fourth quarter of 1993.

         GEOILBENT identified nine previously existing delineation wells that
were capable of being reentered and placed these on production. These
delineation wells were not originally intended by Purneftegasgeologia to be
commercial producers. Therefore, completion procedures for optimum production
were not employed. The Company believes that production rates from future wells
using western completion technologies will be significantly greater. GEOILBENT
has commenced drilling a series of development wells in the North Gubkinskoye
Field. Three Russian drilling rigs are drilling development wells offsetting
previously drilled exploration wells.

         GEOILBENT is utilizing Russian equipment and personnel whenever
feasible. Supervision is provided jointly by an American and Russian management
team. Russian equipment, including Russian rigs, are being upgraded by certain
western technology and materials including shaker screens, monitoring equipment
and drilling and completion fluids. Such measures, along with paying for Russian
equipment and personnel in rubles, allows GEOILBENT to minimize its investment
and operating expenses.

         Russia has established an export tariff on all oil exported from Russia
which, as imposed, has the effect of significantly reducing the cash flows and
potential profits to the Company. However, Russia has issued or drafted various
decrees and legislation under which certain oil and gas joint ventures,
including GEOILBENT, are eligible for relief from such oil export tariff until
such time as they have recovered their capital investment. GEOILBENT has
received a waiver from the export tariff for 1995, and expects to apply for
renewal of such waiver for 1996 and 1997. However, there can be no assurance
that any such renewals can be obtained. Furthermore, after the waiver for 1995
was issued to GEOILBENT, a new Russian law came into force which repeals all tax
and customs benefits previously granted to participants in foreign economic
activities, except for those granted pursuant to certain federal laws, including
the law "On Customs Tariff". While it is not clear whether the repeal applies to
GEOILBENT'S waiver for 1995, GEOILBENT believes that its waiver should be
regarded as granted pursuant to the law "On Customs Tariff". The legislative and
regulatory environment in Russia continues to be subject to frequent change and
uncertainty. The Company believes that the joint venture partners will
continually assess regulatory and economic conditions affecting the Russian
operations, make investment decisions accordingly and make adjustments to the
amount and/or timing of contribution requirements as appropriate and permitted
under the law. In addition, the license which grants GEOILBENT the right to
develop the North Gubkinskoye Field sets forth required levels of oil and gas
production through the year 2000 and requires GEOILBENT to make additional
royalty payments in the event that such production levels are not achieved
during any three year period.

         As part of its plan to fund the development of the North Gubkinskoye
Field, the Company has retained Morgan Guaranty to act as financial advisor to
the Company and GEOILBENT in obtaining project debt financing. Morgan Guaranty
has assisted the Company in approaching multilateral financial institutions and
export finance agencies. Any retainer and percentage success fees paid to Morgan
Guaranty will be credited as the Company's capital contribution. There can be no
assurance that such financing will become available on terms acceptable to the
Company or GEOILBENT.


                                      107
<PAGE>   121
         GEOILBENT has been successful, on a limited basis, in obtaining working
capital funding from certain institutions in Moscow. NAFTA Moscow, the exporter
which handles GEOILBENT's oil sales, made a short-term production payment
advance during the quarter ended March 331, 1995 of $3.0 million. International
Moscow Bank, which is majority owned by non-Russian European banks, has made
two short-term loans to GEOILBENT totaling $6 million. The bank loans were
guaranteed by the Company, which is providing certain portions of the cash for
such debt service during 1995 to complete its charter fund obligation.

RECENT EVENTS

         On June 30, 1995, Benton issued $20 million in 13% senior unsecured
notes due June 30, 2007. Interest is payable semi-annually on June 30 and
December 30, beginning December 30, 1995. Annual principal payments of $4
million are due on June 30 of each year, beginning June 30, 2003. The proceeds
from the note offering will be used primarily for the continued development of
Benton's Venezuelan project and for working capital purposes.

                   INFORMATION CONCERNING 1989-1 PARTNERSHIP

GENERAL

         Objectives. The 1989-1 Partnership is a limited partnership which was
formed to invest in oil and natural gas activities by acquiring proven producing
properties that have additional development potential, recompleting previously
drilled wells and drilling new wells. The primary financial objective of the
1989-1 Partnership is to make quarterly distributions to its Investors from
available cash flow while replacing and expanding its reserves on a
cost-effective basis. The Partnership made regular distributions to partners
through August 1994, but has not made subsequent cash distributions due to
declining oil and gas production combined with higher lease operating expenses
and production taxes, continued capital expenditures and lower natural gas
prices.

         Management. Benton Oil and Gas Company and a wholly-owned subsidiary,
Benton Oil and Gas Company of Louisiana, are the Co-Managing General Partners.
Benton makes all decisions regarding the business and operations of the 1989-1
Partnership, including production, development and other activities, and any
sale of properties and the acquisition of additional properties.

         The Managing General Partners receive 1.0% of the oil and gas revenues
on proven producing wells, 25.75% of the oil and gas revenues on recompleted
wells and 35.65% of the oil and gas revenues on new wells. In addition, Benton
and its subsidiary own 2.8182 Units in the 1989-1 Partnership.

         The Co-Managing General Partners do not receive any management fees or
other fees from the 1989-1 Partnership. The 1989-1 Partnership pays the
Co-Managing General Partners for lease operating expenses, well costs and
general and administrative expenses incurred on behalf of the Partnership.
Benton pays the 1989-1 Partnership for revenues collected on behalf of the
Partnership.

         Organization. Benton, as managing general partner and sponsor of the
1989-1 Partnership, sold an aggregate of $1,409,091 in 1989-1 Units. Of the net
proceeds raised of $1,260,214 which were available for partnership activities,
$815,526 was used in oil and gas activities of the Partnerships, as contemplated
in the private placement memorandum for the offering, and the remaining proceeds
were distributed to the participants.

DESCRIPTION OF OIL AND GAS PROPERTIES

         The following table sets forth certain information as of January 1,
1995 related to the 1989-1 Partnership's interest in its oil and gas

</TABLE>

         Additional information regarding these fields is set forth below.

         Umbrella Point Field. The Umbrella Point Field is located in State
Tracts 74 and 87, which consist of 1,280 acres in the northern end of Upper
Galveston Bay, in Texas state waters. Sun Oil Co. discovered the field in May,
1957. Oil and gas production is from fifteen stacked Frio sands ranging in depth
from the F-1 sand at 7,612 feet to the F-15 sand at 8,994 feet. The 1989-1
Partnership has a 4.93% working interest in the Umbrella Point Field with 10
wells producing, as of April 1995, at combined average daily rates of 342 Bbl of
oil and 3.4 MMcf of natural gas.

East Cameron Block 229. East Cameron Block 229 is located on 5,000 acres in
federal waters eighty miles off the coast of Grand Chenier, Louisiana in the
Gulf of Mexico. The 1989-1 Partnership has a 6.57% working interest in East
Cameron Block 229. Cumulative expenditures by the 1989-1 Partnership on East
Cameron Block 229 are $145,775. As of January 1, 1995, the 1989-1
Partnership's interest in East Cameron Block 229 was determined to be
uneconomic.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF 
OPERATIONS

General

         Benton Oil & Gas Combination Partnership 1989-1, L.P. was formed July
31, 1989 for the purpose of investing in oil and natural gas activities by
acquiring proven producing properties, recompleting previously drilled wells and
developing and drilling oil and gas wells in the state waters of Texas and
off-shore Louisiana. Benton Oil and Gas Company and a wholly owned subsidiary
are the Co-Managing General Partners, and as such, conduct, direct and exercise
full control over all activities of the Partnership.

         Oil and gas properties are accounted for using the successful efforts
methods. Under this method, costs of drilling exploratory wells are initially
capitalized pending determination of whether the well can produce proved
reserves. All costs relating to the non-productive exploratory wells are
expensed. Costs relating to productive exploratory wells and all development
wells are capitalized and depleted on a unit-of-production basis over the life
of the remaining proved developed reserves. Delay rentals and geological and
geophysical costs are expensed as incurred.

         Under the terms of the 1989-1 Partnership Agreement, the participants
pay 99% of the lease acquisition, geophysical and seismic costs, well costs,
general and administrative expenses, and organization and offering expenses,
including commissions, while the Co-Managing General Partners pay 1% of such
costs. Revenues, production taxes and lease operating expenses on proven
producing wells are allocated 99% to the participants and 1% to the Co-Managing
General Partners. Revenues, production taxes and lease operating expenses on
recompleted wells are allocated 74.25% to the participants and 25.75% to the
Co-Managing General Partners. One new wells drilled, revenues, production taxes
and lease operating expenses are allocated 64.35% to the participants and 35.65%
to the Co-Managing General Partners.

Results of Operations

         Three Months Ended March 31, 1995 and 1994. For the three months ended
March 31, 1995, the 1989-1 Partnership had revenues of $30,781 compared to
$41,522 for the same period in 1994, representing a decrease of 26%. This
decrease was primarily due to reduced oil and gas sales from the Umbrella Point
Field due to the field's natural production decline. The production for the
three months ended March 31, 1995 was 1,007 Bbl of crude oil and condensate and
8,758 Mcf of natural gas compared to production of 1,476 Bbl of crude oil and
condensate and 9,440 Mcf of natural gas for the comparable period in 1994. For
the three months ended March 31, 1995, crude oil and natural gas prices, net of
severance taxes, averaged $16.89 per Bbl and $1.57 per Mcf, respectively,
compared to $13.24 per Bbl and $2.27 per Mcf, respectively, during the
comparable period.

         Lease operating costs and production taxes for the period ended March
31, 1995 were $15,203, an increase of 5% from $14,433 in the comparable period.
The increase was primarily due to increases in associated production overhead
and taxes at the Umbrella Point Field. Depletion, impairment and amortization
expenses were $42,934 for the period ended March 31, 1995, an increase of 96%
from $21,880 for the comparable period primarily due to the impairment of the
Umbrella Point Field as a result of the proposed sale of the property. General
and administrative expenses were $17,752 for the period ended March 31, 1995, a
decrease of 4% from $18,469 for the comparable period.


                                      112
<PAGE>   126

         For the reasons discussed above, the net loss for the three months
ended March 31, 1995 was $45,108, compared to a loss of $13,260 for the period
ended March 31, 1994.

         Years Ended December 31, 1994 and 1993. For the year ended December 31,
1994, the 1989-1 Partnership had total revenues of $160,413 compared to $203,380
for the same period in 1993, representing a decrease of 21%, primarily due to
decreased prices. The production for the year ended December 31, 1994 was 5,475
Bbl of crude oil and condensate and 38,044 Mcf of natural gas compared to
production of 5,773 Bbl of crude oil and condensate and 47,433 Mcf of natural
gas for the comparable period in 1994. For the year ended December 31, 1994,
crude oil and natural gas prices, net of severance taxes, averaged $15.47 per
Bbl and $1.95 per Mcf, respectively, compared to $17.09 per Bbl and $2.12 per
Mcf, respectively, during the comparable period.

         Lease operating costs and production taxes for the year ended December
31, 1994 were $79,479, an increase of 3% from $76,855 in the comparable period.
Depletion, impairment and amortization expenses were $77,895 for the year ended
December 31, 1994, an increase of 8% from $72,453 for the comparable period.
General and administrative expenses were $33,654 for the year ended December 31,
1994, a decrease of 12% from $38,432 for the comparable period.

         For the reasons discussed above, the net loss for the year ended
December 31, 1994 was $31,404, compared to net income of $13,749 for the year
ended December 31, 1993.

         Years Ended December 31, 1993 and 1992. For the year ended December 31,
1993, the 1989-1 Partnership had total revenues of $203,380 compared to $225,460
for the same period in 1992, representing a decrease of 10%. The production for
the year ended December 31, 1993 was 5,773 Bbl of crude oil and condensate and
47,433 Mcf of natural gas compared to production of 6,947 Bbl of crude oil and
condensate and 47,323 Mcf of natural gas for the comparable period in 1992. For
the year ended December 31, 1993, crude oil and natural gas prices, net of
severance taxes, averaged $17.09 per Bbl and $2.12 per Mcf, respectively,
compared to $18.72 per Bbl and $1.79 per Mcf, respectively, during the
comparable period.

         Depletion, impairment and amortization expenses were $72,453 for the
year ended December 31, 1993, compared to $111,050 for the same period in 1992,
representing a decrease of 35%. This decrease was primarily due to the complete
depletion of the East Cameron Field in 1992 and was partially offset by
increased depletion of the Umbrella Point Field. General and administrative
expenses for the year ended December 31, 1993 were $38,432 an increase of 20%
from $32,110 in the comparable period.

         For the reasons discussed above, the net income for the year ended
December 31, 1993 was $13,749, compared to net income of $7,364 for the year
ended December 31, 1992.

Capital Resources and Liquidity

         The oil and gas industry is a highly capital intensive business. The
Partnership requires capital principally to fund the following costs: (i)
drilling and completion costs of wells and the cost of production and
transportation facilities; (ii) purchase of leases and other interests in oil
and gas producing properties; and (iii) general and administrative expenses. The
amount of available capital significantly affects the scope of the Partnership's
operations.

         In June 1995, the Partnership entered into an agreement to sell its
principal remaining oil and gas properties (see Note 4 to the 1989-1 Partnership
Financial Statements). Assuming the sale is completed, 

                                      113
<PAGE>   127


the Partnership will have no further oil and gas activities. If the sale is not
completed, the properties have a remaining economic life of approximately 3.5
years.

Effects of Inflation and Changing Prices

         The 1989-1 Partnership's results of operations and cash flow are
affected by changing oil and gas prices. If the price of oil and gas increases,
there could be a corresponding increase in the cost to the Partnership for
drilling and related services as well as an increase in revenues. To date,
inflation has had a minimal effect on the Partnership.

                   INFORMATION CONCERNING 1990-1 PARTNERSHIP

GENERAL

         Objectives. The 1990-1 Partnership is a limited partnership which was
formed to invest in oil and natural gas activities by primarily acquiring proven
producing properties that have additional development potential, recompleting
previously drilled wells and drilling new wells. The primary financial objective
of the 1990-1 Partnership is to make quarterly distributions to its Investors
from available cash flow while replacing and expanding its reserves on a
cost-effective basis. The Partnership made regular cash distributions to
partners through August 1994, but has not made subsequent cash distributions due
to declining oil and gas production combined with higher lease operating costs
and production taxes, continued capital expenditures and lower natural gas
prices.

         Management. Benton Oil and Gas Company and a wholly-owned subsidiary,
Benton Oil and Gas Company of Louisiana, are the Co-Managing General Partners.
Benton makes all decisions regarding the business and operations of the 1990-1
Partnership, including production, development and other activities, and any
sale of properties and the acquisition of additional properties.

         The Managing General Partners receive 25.5236% of the oil and gas
revenues from the 1990-1 Partnership. In addition, Benton and its subsidiary
own 14.192 Units in the 1990-1 Partnership.

         The Co-Managing General Partners do not receive any management fees or
other fees from the 1990-1 Partnership. The 1990-1 Partnership pays the
Co-Managing General Partners for lease operating expenses, well costs and
general and administrative expenses incurred on behalf of the Partnership.
Benton pays the 1990-1 Partnership for revenues collected on behalf of the
Partnership.

         Organization. Benton, as managing general partner and sponsor of the
1990-1 Partnership, sold an aggregate of $7,088,000 of 1990-1 Units. Of the net
proceeds raised of $6,070,551 which were available for partnership activities,
$5,007,909 was used in oil and gas activities of the Partnership, as
contemplated in the private placement memorandum for the offering, and the
remaining proceeds were distributed to the participants.

         Additional information regarding these fields is set forth below.

         Umbrella Point Field. The Umbrella Point Field is located in State
Tracts 74 and 87, which consist of 1,280 acres in the northern end of Upper
Galveston Bay, in Texas state waters. Sun Oil Co. discovered the field in May,
1957. Oil and gas production is from fifteen stacked Frio sands ranging in depth
from the F-1 sand at 7,612 feet to the F-15 sand at 8,994 feet. The 1990-1
Partnership originally acquired a 17.02% working interest in the Umbrella Point
Field in 1990 for. However, in 1991, it sold a 2.83% working interest to the
1991-1 Partnership for $373,205 prior to closing adjustments. The 1990-1
Partnership has a 14.19% working interest in the Umbrella Point Field with 10
wells producing, as of April 1995, at combined average daily rates of 342 Bbl of
oil and 3.4 MMcf of natural gas.

         West Cote Blanche Bay Field. The West Cote Blanche Bay Field is located
on 5,892 acres in a shallow bay in St. Mary Parish, Louisiana, approximately 125
miles southwest of New Orleans with water depths averaging seven to eight feet.
The field was discovered in 1938 by Texaco, which continues to operate the
field. More than 300 separate oil and gas reservoirs have been identified by
Texaco and the Company from a total of approximately 680 wellbores in 180
different sandstone formations, at depths from 1,700 to 13,000 feet. The 1990-1
Partnership originally purchased a 0.38% working interest in the West Cote
Blanche Bay Field in 1990. However, in 1991, it sold a 0.06% working interest to
the 1991-1 Partnership for $94,352 prior to closing adjustments. In March
1995, the Partnership sold a 0.32% working interest in certain depths (above
approximately 10,575 feet), in the West Cote Blanche Bay Field for a purchase
price of $146,900. The 1990-1 Partnership has a 0.32% working interest in three
wells below the depth of approximately 10,575 feet. These wells are currently
producing at a combined rate of approximately 7 MMcf of natural gas per day.

         East Cameron Block 229. East Cameron Block 229 is located on 5,000
acres in federal waters eighty miles off the coast of Grand Chenier, Louisiana
in the Gulf of Mexico. The 1990-1 Partnership has a 22.85% working interest in
East Cameron Block 229. Cumulative expenditures by the 1990-1 Partnership on
East Cameron Block 229 are $946,078. As of January 1, 1995, the 1990-1
Partnership's interest in East Cameron Block 229 was determined to be
uneconomic.

         The following is a description of properties in which the 1990-1
Partnership owned an interest, but subsequently sold or abandoned.

         Round Mountain Field. The Round Mountain Field is located on the
southeast flank of the San Joaquin Basin of Kern County, California,
approximately 10 miles northeast of Bakersfield. The field was discovered in
1927 and average drilling depths range from 1,400 feet to 2,100 feet. The
1990-1 Partnership purchased an 8.40% working interest in 32 producing wells 
in the Round Mountain Field. However, due to the inability to significantly
increase production and after $787,595 in cumulative expenditures, Benton
determined it was in the best interest of the Partnership to sell its working
interest in Round Mountain Field. In September 1992, the 1990-1 Partnership
sold its interest in Round Mountain to Nahama & Weagant Energy Company for
$19,386.
        
         Hopper Canyon 12-1 Well. The Hopper Canyon 12-1 well is located in
Ventura County, California. This well was successfully drilled and completed in
the fourth quarter of 1991. The well produced at rates of approximately 24 Bbl
of oil and 45 MMcf of gas per day. However, Benton determined it was in the best
interest of the Partnership to sell its 38.0% working interest in the well. In
April 1992, the 1990-1 Partnership sold its interest in the 12-1 well to
Fortune Petroleum. Proceeds from the sale were $17,881, consisting of $3,461 in
cash and stock of Fortune Petroleum with a fair market value of $14,420 (the
stock was subsequently sold in November 1994 with the 1990-1 Partnership
receiving $7,672). In addition, the 1990-1 Partnership retained a production
payment of $8,845 which was paid from monthly net income from the 12-1 well. The
1990-1 Partnership's cumulative expenditures on the Hopper Canyon 12-1 well
were $211,134.

         Prather 43-1 Well. This prospect was located in Acadia Parish,
Louisiana. This well was drilled to a total depth of approximately 11,000 feet.
It was determined to be uneconomical and was plugged and abandoned. The 1990-1
Partnership had a 12.5% working interest in this well with total expenditures of
$96,225.

         North Fisher Reef #13-16A Well. This prospect was located in Trinity
Bay, Chambers County, Texas. This offshore oil and gas prospect was drilled to a
total depth of 11,000 feet in February 1991. This prospect had multiple
objectives, however, all objectives were determined to be non-commercial and the
well was plugged and abandoned. The 1990-1 Partnership had a 44.67% working
interest in this well with cumulative expenditures of $134,715.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF 
OPERATIONS

General

         The 1990-1 Partnership was formed November 29, 1990 for the purpose of
investing in oil and natural gas activities by acquiring proven producing
properties, recompleting previously drilled wells and developing and drilling
new oil and gas wells. Benton Oil and Gas Company and a wholly owned subsidiary
are the Co-Managing General Partners, and as such, conduct, direct and exercise
full control over all activities of the Partnership.

         Oil and gas properties are accounted for using the successful efforts
methods. Under this method, costs of drilling exploratory wells are initially
capitalized pending determination of whether the well can produce proved
reserves. All costs relating to non-productive exploratory wells are expensed.
Costs relating to productive exploratory wells and all development wells are
capitalized and depleted on a unit-of-production basis over the life of the
remaining proved developed reserves. Delay rentals and geological and
geophysical costs are expensed as incurred.

         Under the terms of the 1990-1 Partnership Agreement, the participants
pay 99% of the lease acquisition, geophysical and seismic costs, well costs, and
organization and offering expenses, including commissions, while the Co-Managing
General Partners pay 1% of such costs. General and administrative expenses and
lease operating expenses are shared 74.25% by the participants and 25.75% by the
Co-Managing General Partners. Revenues and production taxes are allocated
73.5974% to the participants and 25.5236% to the Co-Managing General Partners
and 0.879% to broker/dealers who met certain minimum sales requirements in the
initial offering of the 1990-1 Units.

Results of Operations

         Three Months Ended March 31, 1995 and 1994. For the three months ended
March 31, 1995, the 1990-1 Partnership had revenues of $96,623 compared to
$129,996 for the same period in 1994, representing a decrease of 22%. This
decrease was primarily due to reduced oil and gas sales from the Umbrella Point
Field due to the field's natural production decline. The production for the
three months ended March 31, 1995 was 3,151 Bbl of crude oil and condensate and
27,325 Mcf of natural gas compared to production of 4,656 Bbl of crude oil and
condensate and 28,917 Mcf of natural gas for the comparable period in 1994. For
the three months ended March 31, 1995, crude oil and natural gas prices, net of
severance taxes, averaged $16.98 per Bbl and $1.57 per Mcf, respectively,
compared to $13.44 per Bbl and $2.25 per Mcf, respectively, during the
comparable period.

         Lease operating costs and production taxes for the period ended March
31, 1995 were $50,961, an increase of 6% from $48,007 in the comparable period.
The increase was primarily due to increases in associated production overhead
and taxes at the Umbrella Point Field. Depletion, impairment and amortization
expenses were $68,276 for the period ended March 31, 1995, an increase of 20%
from $56,795 for the comparable period primarily due to the impairment of the
East Cameron Field as a result of the proposed property sale. General and
administrative expenses were $37,251 for the period ended March 31, 1995, an
increase of 27% from $29,314 for the comparable period.

         For the reasons discussed above, the net loss for the three months
ended March 31, 1995 was $62,086, compared to a loss of $5,289 for the period
ended March 31, 1994.

         Years Ended December 31, 1994 and 1993. For the year ended December 31,
1994, the 1990-1 Partnership had total revenues of $524,786 compared to $645,459
for the same period in 1993, representing a decrease of 19%, primarily due to
price decreases. The production for the year ended December 31, 1994 was 17,179
Bbl of crude oil and condensate and 127,779 Mcf of natural gas compared to
production of 18,518 Bbl of crude oil and condensate and 146,746 Mcf of natural
gas for the comparable period in 1993. For the year ended December 31, 1994,
crude oil and natural gas prices, net of severance taxes, averaged $15,83 per
Bbl and $1.93 per Mcf, respectively, compared to $17.31 per Bbl and $2.11 per
Mcf, respectively, during the comparable period.

         Lease operating costs and production taxes for the year ended December
31, 1994 were $263,957, an increase of 4% from $254,903 in the comparable
period. Depletion, impairment and amortization expenses were $224,635 for the
year ended December 31, 1994, an increase of 19% from $189,309 for the
comparable period primarily due to impairment of the West Cote Blanche Bay 
Field.  General and administrative expenses were $78,547 for the year ended 
December 31, 1994, a decrease of 21% from $99,967 for the comparable period.

         For the reasons discussed above, the net loss for the year ended
December 31, 1994 was $48,960, compared to net income of $91,710 for the year
ended December 31, 1993.

         Years Ended December 31, 1993 and 1992. For the year ended December 31,
1993, the 1990-1 Partnership had total revenues of $645,459 compared to $770,517
for the same period in 1992, representing a decrease of 16%. This decrease was
primarily due to reduced oil and gas sales from the Umbrella Point and East
Cameron Fields due to the fields' natural production decline and sales of the
Round Mountain and Hopper Canyon properties. The production for the years ended
December 31, 1993 was 18,518 Bbl of crude oil and condensate and 146,746 Mcf of
natural gas compared to production of 26,184 Bbl of crude oil and condensate and
145,477 Mcf of natural gas for the comparable period in 1992. For the year ended
December 31, 1993, crude oil and natural gas prices, net of severance taxes,
averaged $17.31 per Bbl and $2.11 per Mcf, respectively, compared to $18.02 per
Bbl and $1.78 per Mcf, respectively, during the comparable period.

         Lease operating costs and production taxes for the year ended December
31, 1993 were $254,903 a decrease of 11% from $285,840 in the comparable period.
Depletion, impairment and amortization expenses were $189,309 for the year ended
December 31, 1993, compared to $1,560,665 for the same period in 1992,
representing a decrease of 88%. This decrease was primarily due to the
impairment of the Round Mountain Field in 1992 as a result of its sale and the
complete depletion of the East Cameron Field in 1992. These decreases were
partially offset by increased depletion of the Umbrella Point Field in 1993.
General and administrative expenses for the year ended December 31, 1993 were
$99,967 an increase of 44% from $69,510 in the comparable period, primarily
related to increased professional fees.

         For the reasons discussed above, the net income for the year ended
December 31, 1993 was $91,710, compared to net loss of $1,212,036 for the year
ended December 31, 1992.

Capital Resources and Liquidity

         The oil and gas industry is a highly capital intensive business. The
Partnership requires capital principally to fund the following costs: (i)
drilling and completion costs of wells and the cost of production and
transportation facilities; (ii) purchase of leases and other interests in oil
and gas producing properties; and (iii) general and administrative expenses. The
amount of available capital significantly effects the scope of the Partnership's
operations.

<PAGE>   133

         In June 1995, the Partnership entered into an agreement to sell its
principal remaining oil and gas properties (see Note 4 to the 1990-1 Partnership
Financial Statements). Assuming the sale is completed, the Partnership will have
very limited remaining oil and gas activities. If the sale is not completed, 
the properties have a remaining economic life of approximately 5.5 years.

Effects of Inflation and Changing Prices

         The 1990-1 Partnership's results of operations and cash flow are
affected by changing oil and gas prices. If the price of oil and gas increases,
there could be a corresponding increase in the cost to the Partnership for
drilling and related services as well as an increase in revenues. To date,
inflation has had a minimal effect on the Partnership.

                   INFORMATION CONCERNING 1991-1 PARTNERSHIP

GENERAL

         Objectives. The 1991-1 Partnership is a limited partnership which was
formed to invest in oil and natural gas activities by primarily acquiring proven
producing properties that have additional development potential, recompleting
previously drilled wells and drilling new wells. The primary financial objective
of the 1991-1 Partnership is to make quarterly distributions to its Investors
from available cash flow while replacing and expanding its reserves on a
cost-effective basis. The Partnership made regular cash distributions to
partners through August 1994, but has not made subsequent cash distributions due
to declining oil and gas production combined with higher lease operating costs
and production taxes, continued capital expenditures and lower natural gas
prices.

         Management. Benton Oil and Gas Company and a wholly-owned subsidiary,
Benton Oil and Gas Company of Louisiana, are the Co-Managing General Partners.
Benton makes all decisions regarding the business and operations of the 1991-1
Partnership, including development and other activities, and any sale of
properties and the acquisition of additional properties.

         The Managing General Partners receive 25.6438% of the oil and gas
revenues from the 1991-1 Partnership. In addition, Benton and its subsidiary
own 2.8182 Units in the 1991-1 Partnership.

         The Co-Managing General Partners do not receive any management fees or
other fees from the 1991-1 Partnership. The 1991-1 Partnership pays the
Co-Managing General Partners for lease operating expenses, well costs and
general and administrative expenses incurred on behalf of the Partnership.
Benton pays the 1991-1 Partnership for revenues collected on behalf of the
Partnership.

         Organization. Benton, as managing general partner and sponsor of the
1991-1 Partnership, sold an aggregate of $1,409,091 of 1991-1 Units. Of the net
proceeds raised of $1,055,886 which were available for partnership activities,
$927,510 was used in oil and gas activities of the Partnership, as contemplated
in the private placement memorandum for the offering, and the remaining proceeds
were distributed to the participants.

         Additional information regarding these fields is set forth below.

         Umbrella Point Field. The Umbrella Point Field is located in State
Tracts 74 and 87, which consist of 1,280 acres in the northern end of Upper
Galveston Bay, in Texas state waters. Sun Oil Co. discovered the field in May,
1957. Oil and gas production is from fifteen stacked Frio sands ranging in depth
from the F-1 sand at 7,612 feet to the F-15 sand at 8,994 feet. The 1991-1
Partnership acquired a 2.83% working interest in the Umbrella Point Field from
the 1990-1 Partnership for $373,205 prior to closing adjustments. As of April
1995, the Umbrella Point Field had 10 wells producing at combined average daily
rates of 342 Bbl of oil and 3.4 MMcf of natural gas.

         West Cote Blanche Bay Field. The West Cote Blanche Bay Field is located
on 5,892 acres in a shallow bay in St. Mary Parish, Louisiana, approximately 125
miles southwest of New Orleans with water depths averaging seven to eight feet.
The field was discovered in 1938 by Texaco, which continues to operate the
field. More than 300 separate oil and gas reservoirs have been identified by
Texaco and the Company from a total of approximately 680 wellbores in 180
different sandstone formations, at depths from 1,700 to 13,000 feet. The 1991-1
Partnership purchased a 0.06% working interest in the West Cote Blanche Bay
Field from the 1990-1 Partnership for $94,352 prior to closing adjustments. In
March 1995, the Partnership sold its 0.06% working interest in certain depths
(above approximately 10,575 feet) in the West Cote Blanche Bay Field for a
purchase price of $29,200. The 1991-1 Partnership has a 0.06% working interest
in three wells below the depth of approximately 10,575 feet. These wells are
currently producing at a combined rate of approximately 7 MMcf of natural gas
per day.

         The following is a description of properties the 1991-1 Partnership
at one time had an interest in but subsequently sold or abandoned.

         Hopper Canyon 12-1 Well. The Hopper Canyon 12-1 well is located in
Ventura County, California. This well was successfully drilled and completed in
the fourth quarter of 1991. The well produced at rates of approximately 24 Bbl
of oil and 45 MMcf of gas per day. However, Benton determined it was in the best
interest of the Partnership to sell its 38.0% working interest in the well. In
April 1992, the 1991-1 Partnership sold its interest in the 12-1 well to
Fortune Petroleum. Proceeds from the sale were $17,881, consisting of $3,461 in
cash and stock of Fortune Petroleum with a fair market value of $14,420 (the
stock was subsequently sold in November 1994 with the 1991-1 Partnership
receiving $7,699). In addition, the 1991-1 Partnership retained a production
payment of $8,845 which was paid from monthly net income from the 12-1 well. The
1991-1 Partnership's cumulative expenditures on the Hopper Canyon 12-1 well
were $211,132.

         Prather 43-1 Well. This prospect was located in Acadia Parish,
Louisiana. This well was drilled to a total depth of approximately 11,000 feet.
It was determined to be uneconomical and was plugged and abandoned. The 1991-1
Partnership had a 17.5% working interest in this well with total cumulative
expenditures of $134,715.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF 
OPERATIONS

General

         The 1991-1 Partnership was formed for the purpose of investing in oil
and natural gas activities by acquiring proven producing properties,
recompleting previously drilled wells and developing and drilling new oil and
gas wells. Benton Oil and Gas Company and a wholly owned subsidiary are the
Co-Managing General Partners, and as such, conduct, direct and exercise full
control over all activities of the Partnership.

         Oil and gas properties are accounted for using the successful efforts
methods. Under this method, costs of drilling exploratory wells are initially
capitalized pending determination of whether the well can produce proved
reserves. All costs relating to non-productive exploratory wells are expensed.
Costs relating to productive exploratory wells and all development wells are
capitalized and depleted on a unit-of-production basis over the life of the
remaining proved developed reserves. Delay rentals and geological and
geophysical costs are expensed as incurred.

         Under the terms of the 1991-1 Partnership Agreement, the participants
pay 99% of the lease acquisition, geophysical and seismic costs, well costs, and
organization and offering expenses, including commissions, while the Co-Managing
General Partners pay 1% of such costs. For the first twelve months of the
Partnership, general and administrative expenses are covered by a fee, equal to
3% of the initial capital raised, paid by the Partnership to Benton. The fee is
paid 99% by the participants and 1% by the Co-Managing General Partners. General
and administrative expenses after the first twelve months and lease operating
expenses are shared 74.25% by the participants and 25.75% by the Co-Managing
General Partners. Revenues and Production taxes are allocated 73.944% to the
participants and 25.6438% to the Co-Managing General Partners, and 0.4122% to
broker/dealers who met certain minimum sales requirements in the initial
offering of 1991-1 Units.

Results of Operations

         Three Months Ended March 31, 1995 and 1994. For the three months ended
March 31, 1995, the 1991-1 Partnership had revenues of $18,430 compared to
$23,753 for the same period in 1994, representing a decrease of 22%. This
decrease was primarily due to reduced oil and gas sales from the Umbrella Point
Field due to the field's natural production decline. The production for the
three months ended March 31, 1995 was 625 Bbl of crude oil and condensate and
4,599 Mcf of natural gas compared to production of 926 Bbl of crude oil and
condensate and 4,155 Mcf of natural gas for the comparable period in 1994. For
the three months ended March 31, 1995, crude oil and natural gas prices, net of
severance taxes, averaged $17.04 per Bbl and $1.61 per Mcf, respectively,
compared to $14.09 per Bbl and $2.35 per Mcf, respectively, during the
comparable period.

         Lease operating costs and production taxes for the period ended March
31, 1995 were $6,596, an increase of 5% from $6,264 in the comparable period.
The increase was primarily due to increases in associated production overhead
and taxes at the Umbrella Point Field. Depletion, impairment and amortization
expenses were $92,063 for the period ended March 31, 1995, an increase of 463%
from $16,350 for the comparable period primarily due to the impairment of the
Umbrella Point Field as a result of the proposed sale of the property. General
and administrative expenses were $14,602 for the period ended March 31, 1995, a
decrease of 21% from $18,395 for the comparable period. The 1991-1 Partnership
had a loss on sale of oil and gas property of $225 for the period ended March
31, 1995.

                                      124
<PAGE>   138

         For the reasons discussed above, the net loss for the three months
ended March 31, 1995 was $95,234, compared to a loss of $17,489 for the period
ended March 31, 1994.

         Years Ended December 31, 1994 and 1993. For the year ended December 31,
1994, the 1991-1 Partnership had total revenues of $98,644 compared to $112,524
for the same period in 1993, representing a decrease of 12%, primarily due to
price decreases. The production for the year ended December 31, 1994 was 3,420
Bbl of crude oil and condensate and 19,815 Mcf of natural gas compared to
production of 3,686 Bbl of crude oil and condensate and 18,256 Mcf of natural
gas for the comparable period in 1993. For the year ended December 31, 1994,
crude oil and natural gas prices, net of severance taxes, averaged $16.83 per
Bbl and $1.94 per Mcf, respectively, compared to $18.14 per Bbl and $2.21 per
Mcf, respectively, during the comparable period.

         Lease operating costs and production taxes for the year ended December
31, 1994 were $38,002, an increase of 5% from $36,276 in the comparable period.
Depletion, impairment and amortization expenses were $95,497 for the year ended
December 31, 1994, an increase of 58% from $60,503 for the comparable period
primarily due to impairment of the West Cote Blanche Bay Field. General and
administrative expenses were $28,823 for the year ended December 31, 1994, a
decrease of 36% from $45,195 for the comparable period.

         For the reasons discussed above, the net loss for the year ended
December 31, 1994 was $64,447, compared to net loss of $30,734 for the period
ended December 31, 1993.

         Years Ended December 31, 1993 and 1992. For the year ended December 31,
1993, the 1991-1 Partnership had total revenues of $112,524 compared to $160,321
for the same period in 1992, representing a decrease of 30%. This decrease was
primarily due to reduced oil and gas sales from the Umbrella Point and West Cote
Blanche Bay Fields due to the fields' natural production decline and sale of the
Hopper Canyon property. The production for the year ended December 31, 1993 was
3,686 Bbl of crude oil and condensate and 18,256 Mcf of natural gas compared to
production of 4,727 Bbl of crude oil and condensate and 19,222 Mcf of natural
gas for the comparable period in 1994. For the year ended December 31, 1993,
crude oil and natural gas prices, net of severance taxes, averaged $18.14 per
Bbl and $2.21 per Mcf, respectively, compared to $20.02 per Bbl and $1.84 per
Mcf, respectively, during the comparable period.

         Lease operating costs and production taxes for the year ended December
31, 1993 were $36,276, a decrease of 10% from $40,093 in the comparable period.
Depletion, impairment and amortization expenses were $60,503 for the year ended
December 31, 1993, compared to $65,241 for the same period in 1992, representing
a decrease of 7%. General and administrative expenses for the year ended
December 31, 1993 were $45,195 an increase of 57% from $28,876 in the comparable
period, primarily related to increased professional fees.

         For the reasons discussed above, the net loss for the year ended
December 31, 1993 was $30,734, compared to net loss of $42,359 for the year
ended December 31, 1992.

Capital Resources and Liquidity

         The oil and gas industry is a highly capital intensive business. The
Partnership requires capital principally to fund the following costs: (i)
drilling and completion costs of wells and the cost of production and
transportation facilities; (ii) purchase of leases and other interests in oil
and gas 

                                      125
<PAGE>   139

producing properties; and (iii) general and administrative expenses. The amount
of available capital significantly effects the scope of the Partnership's
operations.

         In June 1995, the Partnership entered into an agreement to sell its
principal remaining oil and gas properties (see Note 4 to the 1991-1
Partnership Financial Statements). Assuming the sale is completed, the
Partnership will have very limited remaining oil and gas activities. If the
sale is not completed, the properties have a remaining economic life of
approximately 2.5 years.

Effects of Inflation and Changing Prices

         The 1991-1 Partnership's results of operations and cash flow are
affected by changing oil and gas prices. If the price of oil and gas increases,
there could be a corresponding increase in the cost to the Partnership for
drilling and related services as well as an increase in revenues. To date,
inflation has had a minimal effect on the Partnership.

                            DESCRIPTION OF SECURITIES

         Benton is authorized to issue 40,000,000 shares of Common Stock and
5,000,000 shares of Preferred Stock.

         Common Stock. The holders of Common Stock are entitled to one vote per
share for each share held of record on all matters submitted to a vote of the
stockholders and are entitled to receive ratably such dividends as are declared
by the Board of Directors out of funds legally available therefor. In the event
of liquidation, dissolution or winding up of Benton, holders of the Common Stock
have the right to a ratable portion of the assets remaining after payment of
liabilities and liquidation preferences of any outstanding shares of Preferred
Stock. The holders of Common Stock have no preemptive rights or rights to
convert their Common Stock into other securities and are not subject to future
calls or assessments by Benton. All outstanding shares of Common Stock are fully
paid and nonassessable. All shares of Common Stock to be issued in connection
with the Sale will be fully paid and nonassessable.

         Preferred Stock. The Board of Directors may, without further action of
the stockholders, issue preferred Stock in one or more series and fix rights and
preferences thereof, including dividend rights, dividend rates, conversion
rights, voting rights, terms of redemption, redemption price or prices,
liquidation preferences and the number of shares constituting any series or the
designation of such series (provided that the Board of Directors has no
authority to issue more than 5,000,000 shares of Preferred Stock). No shares of
Preferred Stock are currently outstanding.

         The rights of the holders of Common Stock will be subject to, and may
be adversely affected by, the rights of the Preferred Stock, which while
providing desirable flexibility in achieving corporate objectives, could have
the effect of making it more difficult for a person to acquire, or of
discouraging a person from acquiring, a majority of the voting stock of Benton.

                                    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 COSTS. "Finding Cost," expressed in dollars per BOE, is
calculated by dividing the amount of total capital expenditures incurred related
to acquisitions, exploration and development costs (reduced by proceeds from 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
non-producing 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.


                                      129
<PAGE>   143

         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.

         MMBTU. "MMBtu" means one million British thermal units. A British
thermal unit is the amount of heat needed to raise the temperature of one pound
of water one degree Fahrenheit.

         NET ACRES OR WELLS. A party's "Net Acre" 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.

         OIL AND GAS LEASE. An "Oil and Gas Lease" is an agreement whereby the
grantee receives for a period of time the full or partial interest in oil and
gas properties, oil and gas mineral rights, fee rights or other rights of the
grantor granting the grantee the right to drill for, produce and sell oil and
gas upon payment of rentals, bonuses and/or royalties. Oil and Gas Leases are
generally acquired from private landowners and federal and state governments.

         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 BEHIND-PIPE RESERVES. "Proved Developed 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.

         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 DISCOUNTED FUTURE NET CASH FLOWS, BEFORE
PROVISION FOR INCOME TAXES. The "Standardized measure of discounted future net
cash flows, before provision for income taxes" is a method of determining the
present value of Proved Reserves. Future net revenues from Proved Reserves are
estimated assuming that oil and gas prices and production and development costs
remain constant. The resulting stream of revenues, before provision for income
taxes, 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
aerially collected seismic data. 3-D surveys allow for a more detailed
understanding of the subsurface than do conventional surveys and contributed
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.

                                      130
<PAGE>   144

         WORKING INTEREST. A "Working Interest" is the operating interest under
an Oil and Gas Lease which gives the owner the right to drill, produce and
conduct operating activities on the property and a share of production, subject
to all royalties, overriding royalties and other burdens and to all costs of
exploration, development and operations and all risks in connection therewith.

         In this Prospectus, natural gas volumes are stated at the legal
pressure base of the state or area in which the reserves are located at 60
degrees Fahrenheit.

                          INDEPENDENT AUDITORS' REPORT
 
Benton Oil and Gas Company
Carpinteria, California
 
     We have audited the accompanying consolidated balance sheets of Benton Oil
and Gas Company and subsidiaries as of December 31, 1994 and 1993, and the
related consolidated statements of operations, stockholders' equity, and cash
flows for each of the three years in the period ended December 31, 1994. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, such consolidated financial statements present fairly, in
all material respects, the financial position of Benton Oil and Gas Company and
subsidiaries as of December 31, 1994 and 1993, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1994 in conformity with generally accepted accounting principles.

                   THREE MONTHS ENDED MARCH 31, 1995 AND 1994
 
NOTE 1 -- ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Benton Oil and Gas Company (the "Company") engages in the exploration,
development, production and management of oil and gas properties.
 
     The Company and its subsidiary Benton Oil and Gas Company of Louisiana,
formerly Energy Partners, participate as the managing general partner of three
oil and gas limited partnerships formed during 1989 through 1991. Under the
provisions of the limited partnership agreements, the Company receives
compensation as stipulated therein, and functions as an agent for the
partnerships to arrange for the management, drilling, and operation of
properties, and assumes customary contingent liabilities for partnership
obligations.
 
     The consolidated financial statements include the accounts of the Company
and its subsidiaries. The Company's investments in limited partnerships, the
Russia joint venture ("GEOILBENT") and the Venezuela joint venture (through
December 31, 1993) are proportionately consolidated based on the Company's
ownership interest. Effective January 1, 1994, the Venezuela joint venture was
incorporated and, as a result of the Company's acquisition of additional capital
stock of such corporation (See Note 11), has been fully consolidated. All
material intercompany profits, transactions and balances have been eliminated.
 
  Cash and Cash Equivalents
 
     Cash equivalents include money market funds and short term certificates of
deposit with original maturity dates of less than three months.
 
  Accounts Receivable
 
     The Company's accounts receivable are considered fully collectible;
therefore, no allowance is considered necessary.
 
  Other Assets
 
     Other assets consist principally of costs associated with the issuance of
long term debt. Debt issue costs are amortized on a straight-line basis over the
life of the debt.
 
  Property and Equipment
 
     The Company follows the full cost method of accounting for oil and gas
properties. Accordingly, all costs associated with the acquisition, exploration,
and development of oil and gas reserves are capitalized as incurred, including
exploration overhead of $1,696,330, $1,736,678 and $1,412,170 for the years
ended December 31, 1994, 1993 and 1992, respectively and $526,161 and $371,530
for the three months ended March 31, 1995 and 1994, respectively. Only overhead
which is directly identified with acquisition, exploration or development
activities is capitalized. All costs related to production, general corporate
overhead and similar activities are expensed as incurred. The costs of oil and
gas properties are accumulated in cost centers on a country by country basis,
subject to a cost center ceiling (as defined by the Securities and Exchange
Commission).
 
     All capitalized costs of oil and gas properties (excluding unevaluated
property acquisition and exploration costs) and the estimated future costs of
developing proved reserves, are depleted over the estimated useful lives of the
properties by application of the unit-of-production method using only proved oil
and gas reserves. Depletion expense attributable to the United States cost
center for the years ended December 31, 1994, 1993 and 1992 was $4,247,304,
$2,142,133 and $2,937,887 ($7.46, $6.47 and $5.71 per equivalent barrel),
respectively and for the three months ended March 31, 1995 and 1994 was $628,270
and $485,064 ($6.97 and

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
$6.49 per equivalent barrel), respectively. Depletion expense attributable to
the Venezuelan cost center for the years ended December 31, 1994 and 1993 was
$4,998,213 and $229,080 ($1.98 and $1.43 per equivalent barrel), respectively
and for the three months ended March 31, 1995 and 1994 was $2,109,428 and
$549,518 ($1.99 and $1.79 per equivalent barrel), respectively. Depletion
expense attributable to the Russian cost center for the years ended December 31,
1994 and 1993 was $837,818 and $99,207 ($2.85 and $3.51 per equivalent barrel),
respectively and for the three months ended March 31, 1995 and 1994 was $328,136
and $84,324 ($2.76 and $3.13 per equivalent barrel), respectively. Depreciation
of furniture and fixtures is computed using the straight-line method, with
depreciation rates based upon the estimated useful life applied to the cost of
each class of property. Depreciation expense was $185,336, $123,623 and $65,213
for the years ended December 31, 1994, 1993 and 1992, respectively and $57,477
and $43,888 for the three months ended March 31, 1995 and 1994, respectively.
 
  Taxes on Income
 
     Deferred income taxes reflect the net tax effects, calculated at currently
effective rates, of (a) future deductible/taxable amounts attributable to events
that have been recognized on a cumulative basis in the financial statements and
(b) operating loss and tax credit carryforwards. A valuation allowance is
recorded, if necessary, to reduce net deferred income tax assets to the amount
expected to be recoverable.
 
  Foreign Currency
 
     Russia and Venezuela are considered highly inflationary economies.
Therefore, all foreign operations are remeasured in United States dollars and
any currency gains or losses are recorded in the statement of operations.
 
  Fair Value of Financial Instruments
 
     The Company's financial instruments consist primarily of cash, accounts
receivable and payable, commercial paper and other short-term borrowings and
debt instruments. In addition, in 1994 the Company entered into a commodity
hedge agreement (See Note 15). The book values of all financial instruments,
other than debt instruments, are representative of their fair values due to
their short-term maturity. The book values of the Company's debt instruments,
except the convertible subordinated debentures and notes, are considered to
approximate their fair values because the interest rates of these instruments
are based on current rates offered to the Company. Based on the last trading on
December 31, 1994, the convertible subordinated debentures had a fair value of
approximately $6,685,000. There is no active market for the convertible
subordinated notes. Based on discounting the future cash flows related to the
notes at interest rates currently offered to the Company, approximately 13%, the
notes would have a fair value of approximately $3,600,000 at December 31, 1994.
The fair value of the hedge agreement is the estimated amount the Company would
have to pay to terminate the agreement, taking into account current oil prices
and the current creditworthiness of the hedge counterparties. The estimated
termination cost associated with the hedge agreement at December 31, 1994 is
approximately $1,132,000.
 
  Interim Reporting
 
     In the opinion of the Company, the accompanying unaudited consolidated
financial statements contain all adjustments (consisting of only normal
recurring accruals) necessary to present fairly the financial position as of
March 31, 1995, and the results of operations for the three month periods ended
March 31, 1995 and 1994.

NOTE 2 -- ACQUISITIONS AND SALES
 
     In February 1992, the Company sold its interests in its Colorado properties
for net proceeds of approximately $0.8 million. Proceeds of the sale were used
primarily to repay portions of the Company's long term debt.
 
     In March 1992, the Company acquired additional working interests in several
oil and gas properties in Louisiana, California and Texas in which the Company
already had an interest. The purchase price was approximately $2.7 million.
After giving effect to certain closing adjustments, including adjustment of
joint interest receivables, the Company issued 213,957 shares of common stock to
the seller as full consideration for the acquisition.
 
     In September 1992, the Company sold the majority of its interests in its
California properties for net proceeds of $2.1 million, which were used to repay
debt.
 
     In June 1993, the Company sold 50% of its interests in the Belle Isle and
Rabbit Island Fields in exchange for reimbursement of certain expenditures
incurred through the closing date plus the additional reimbursement of certain
future costs as incurred. As of December 31, 1994, $6.5 million of the Company's
costs have been reimbursed. Additionally, in May 1993, the Company sold its
interest in the South Scott Prospect in Lafayette Parish, Louisiana for $1.5
million. The proceeds from these sales were used for working capital purposes.
 
     In March 1994, the Company acquired capital stock from Vinccler
representing an additional 30% ownership interest in Benton-Vinccler for $3
million in cash, $10 million in non-interest bearing notes payable (with a
present value of $9.2 million assuming a 10% interest rate) payable in various
installments over 24 months and 200,000 shares of the Company's common stock.
The excess of the purchase price over the book value of the 30% interest was
allocated to oil and gas properties.
 
     In November 1994, the Company sold a 10.8% working interest (24.9% of the
Company's 43.3% working interest) in the West Cote Blanche Bay Field for
approximately $5.8 million and future consideration of up to $3.7 million.
 
     In March 1995, the Company sold its 32.5% working interest in certain
depths (above approximately 10,575 feet) in the West Cote Blanche Bay Field for
a purchase price of approximately $14.9 million. The sales price has been
reflected as property held for sale at December 31, 1994.

     On September 30, 1994, the Company issued $15 million in senior unsecured
notes due September 30, 2002, with interest at 13% per annum. Interest is
payable semi-annually on March 30 and September 30 beginning March 30, 1995.
Annual principal payments of $3 million are due on September 30 of each year
beginning on September 30, 1998. Early payment of the notes could result in a
substantial prepayment penalty. The note agreement contains financial covenants
including a minimum ratio of current assets to current liabilities and a maximum
ratio of liabilities to net worth or domestic oil and gas reserves. The note
agreement also provides for limitations on liens, additional indebtedness,
certain capital expenditures, dividends, sales of assets and mergers.
Additionally, in connection with the issuance of the notes, the Company issued
warrants entitling the holder to purchase 250,000 shares of common stock at
$9.00 per share, subject to adjustment in certain circumstances, that are
exercisable on or before September 30, 2002.
 
     On December 27, 1994, the Company entered into a revolving secured credit
facility. Under the credit agreement, the Company may borrow up to $15 million,
with the initial available principal limited to $10 million, on a revolving
basis for two years, at which time the facility will become a term loan due

December 31, 1999. Borrowings under the credit agreement are secured in part by
mortgages on the Company's U.S. properties and in part by a guarantee provided
by the financial institution which arranged the credit facility. Interest on
borrowings under the credit agreement accrues, at the Company's option, at
either a floating rate (higher of prime rate plus 3% or the Federal Funds Rate
plus 5%) or a fixed rate (rate of interest at which deposits of dollars are
available to lender in the interbank eurocurrency market plus 4.5%). The
floating rate borrowings may be prepaid at any time without penalty and the
fixed rate borrowings may be repaid on the last day of an interest period
without penalty, or at the option of the Company during an interest period upon
payment of a make-whole premium. The credit agreement contains financial
covenants including a minimum ratio of current assets to current liabilities and
maximum ratio of liabilities to net worth or domestic oil and gas reserves, and
also provides for limitations on liens, dividends, sales of assets and mergers.
Additionally, in exchange for the credit enhancement, the arranging financial
institution and commercial bank received warrants entitling the holder to
purchase 50,000 shares of common stock at $12.00 per share, subject to
adjustment in certain circumstances, that are exercisable on or before December
2004, and the arranging institution receives a 5% net profits interest in the
Company's properties whose development is financed by the facility.
 
     In May 1992, the Company issued $6,428,000 aggregate principal amount of
publicly offered 8% Convertible Subordinated Debentures due May 1, 2002,
convertible at the option of the holder at 101.157 shares per $1,000 principal
amount with interest payments due May 1 and November 1. Net proceeds to the
Company were approximately $5,711,000 and were used primarily to repay certain
indebtedness. At the Company's option, it may redeem the debentures in whole or
in part at any time on or after May 1, 1994, at 105% of par plus accrued
interest, declining annually to par on May 1, 1999. The debentures also provide
that the holders can redeem their debentures following a change in control (as
defined) of the Company. The Company has the option to pay the repurchase price
in cash or shares of its common stock.
 
     In October 1991, the Company issued $4,662,000 aggregate principal amount
of privately placed 8% Convertible Subordinated Notes ("Notes") due October 1,
2001, convertible at the option of the note holder at 85.259 shares per $1,000
principal amount with interest payments due April 1 and October 1. Net proceeds
to the Company were approximately $4,237,000. At the Company's option it may
prepay the Notes in whole or in part at any time on or after October 1, 1993 at
105% of the principal amount plus accrued interest declining annually to the
principal amount on October 1, 1998. The Notes also provide that the holders can
redeem their Notes in cash following a change in control (as defined) of the
Company.
 
     In August 1994, GEOILBENT entered into an agreement with International
Moscow Bank for a $4 million loan with the following terms: 14 monthly payments,
interest at LIBOR plus 7.5%, with interest only payments for the first four
months and monthly principal and interest payments thereafter. In connection
with this agreement, the Company provided to International Moscow Bank a
guarantee of payment under which the Company has agreed to pay such loan in full
if GEOILBENT fails to make the scheduled payments. At December 31, 1994, the
Company's share of the outstanding balance was $1.3 million. In March 1995,
GEOILBENT's credit facility with International Moscow Bank was expanded by $3
million to $6 million, with interest only payments on the additional $3 million
for 3 months and monthly principal and interest payments thereafter. The Company
has similarly guaranteed this indebtedness, through which the Company intends to
fulfill substantially all of its remaining charter fund contribution
requirements. At March 31, 1995, the Company's share of the outstanding balance
was approximately $2.0 million.

NOTE 4 -- COMMERCIAL PAPER AND OTHER SHORT TERM BORROWINGS
 
     In October 1993, Benton-Vinccler issued $15 million in commercial paper,
with interest at 8.5%, for project financing. At December 31, 1993, the
Company's share of the commercial paper outstanding was approximately $7.3
million. At the February 1994 maturity date of the commercial paper,
Benton-Vinccler borrowed $15 million from Morgan Guaranty Trust Company of New
York ("Morgan Guaranty") to repay the commercial paper. Benton-Vinccler
subsequently borrowed from the same bank an additional $7 million for working
capital requirements. The credit facility is collateralized in full by time
deposits from the Company, bears interest at LIBOR plus 3/4%, and is renewed on
a monthly basis. Under the loan arrangement, Benton-Vinccler may borrow up to
$25 million, of which $10 million may be borrowed on a revolving basis. The loan
arrangement contains no restrictive covenants and no financial ratio covenants.
Benton-Vinccler made a payment of $2.75 million in September 1994, leaving a
balance of $19.25 million. The Company is presently pursuing several options for
long term financing for Benton-Vinccler.
 
     During the fourth quarter of 1994 and the first quarter of 1995,
Benton-Vinccler acquired approximately $4.1 million of drilling and production
equipment from trading companies and suppliers under terms which include
repayment within a 12-month period in monthly and quarterly installments at
interest rates from 6.7% to 10%. The outstanding balances at March 31, 1995 and
December 31, 1994 related to these transactions were approximately $3.0 and $1.5
million, respectively.
 
     In June 1994, GEOILBENT entered into a production payment advance agreement
with NAFTA Moscow, the export agency which markets GEOILBENT's oil production to
purchasers in Europe. The payment advance of $2.5 million against future oil
shipments, which bore an effective discount rate of 12% was repaid through
withholdings from oil sales on a monthly basis through December 1994. During the
quarter ended March 31, 1995, GEOILBENT received $3.0 million in production
payment advances pursuant to a similar agreement with NAFTA Moscow containing
similar terms. At March 31, 1995, the Company's share of the unpaid advances was
approximately $1.0 million.
 
NOTE 5 -- COMMITMENTS AND CONTINGENCIES
 
     The state leases relating to the West Cote Blanche Bay Field, the portion
of the Belle Isle Field owned by Texaco and the Rabbit Island Field, were the
subject of litigation between Texaco and the State of Louisiana. The Company's
interests in the Fields, which include substantially all of the Company's
domestic reserves, were originally owned by Texaco under certain leases granted
by the State. Although the Company was not a party to this litigation, its
interests in the Fields were subject to the litigation. In February 1994, the
State and Texaco entered into a Global Settlement Agreement to settle all
disputes related to this litigation. As a result of this agreement, Texaco has
committed to certain acreage development and drilling obligations which may
affect the Company and certain of its Louisiana properties. The Company believes
that the settlement and the

subsequent sale of the working interest by Texaco to Apache Corporation should
have no effect on its proved reserves and should have no material adverse effect
on the Company.
 
     In the normal course of its business, the Company may periodically become
subject to actions threatened or brought by its investors or partners in
connection with the operation or development of its properties or the sale of
securities. Prior to 1992, the Company was engaged in the formation and
operation of oil and gas limited partnership interests. In 1992, the Company
ceased raising funds through such sales. In connection with its continuing role
as managing general partner of certain limited partnerships, the Company may
become subject to actions brought by limited partners of these partnerships.
Certain of such limited partners have brought an action against the Company in
connection with the Company's operation of the limited partnerships as managing
general partner. The plaintiffs seek actual and punitive damages for alleged
actions and omissions by the Company in operating the partnerships and alleged
misrepresentations made by the Company in selling the limited partnership
interests. The Company intends to vigorously defend this action and does not
believe the claims raised are meritorious. However, new developments could alter
this conclusion at any time. The Company will be forced to expend time and
financial resources to defend or resolve any such matters. The Company is also
subject to ordinary litigation that is incidental to its business. None of the
above matters are expected to have a material adverse effect on the Company.
 
     The Company's aggregate rental commitments and related sub-leases, for
noncancellable agreements at December 31, 1994, are as follows:

     The provision for income taxes for 1994 consists primarily of foreign
income taxes currently payable. The Company is providing for deferred income
taxes on undistributed earnings of foreign subsidiaries.
 
     The Company has provided a valuation allowance for the excess benefits of
operating loss and tax credit carryforwards. As of December 31, 1994, the
Company had, for federal income tax purposes, operating loss carryforwards of
approximately $32.4 million, expiring in the years 2003 through 2009. If the
carryforwards are ultimately realized, approximately $3.0 million will be
credited to additional paid-in capital for tax benefits associated with
deductions for income tax purposes related to stock options. The Company has
available approximately $12.4 million and approximately $1.5 million of net
operating loss carryforwards for state and foreign income tax purposes,
respectively.
 
NOTE 7 -- STOCK OPTIONS
 
     The Company adopted its 1988 Stock Option Plan in December 1988 authorizing
options to acquire up to 418,824 shares of common stock. Under the plan,
incentive stock options were granted to key employees and other options, stock
or bonus rights were granted to key employees, directors, independent
contractors and consultants at prices equal to or below market price,
exercisable over various periods.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     The Company adopted its 1989 Nonstatutory Stock Option Plan during 1989
covering 2,000,000 shares of common stock which were granted to key employees,
directors, independent contractors and consultants at prices equal to or below
market prices, exercisable over various periods. The plan was amended during
1990 to add 1,960,000 shares of common stock to the plan.
 
     As shares became exercisable under the 1988 and 1989 plans, the Company
recorded compensation expense (a portion of which is associated with exploration
overhead and is therefore capitalized) to the extent that the market price on
the date of grant exceeded the option price. For years ended December 31, 1993
and 1992, compensation expense of $142,420 and $329,103, respectively, has been
recorded.
 
     In September 1991, the Company adopted the 1991-1992 Stock Option Plan and
the Directors' Stock Option Plan. The 1991-1992 Stock Option Plan permits the
granting of stock options to purchase up to 2,500,000 shares of the Company's
common stock in the form of incentive stock options ("ISOs") and nonqualified
stock options ("NQSOs") to officers and employees of the Company. Options may be
granted as ISOs, NQSOs or a combination of each, with exercise prices not less
than the fair market value of the common stock on the date of the grant. The
amount of ISOs that may be granted to any one participant is subject to the
dollar limitations imposed by the Internal Revenue Code of 1986, as amended. In
the event of a change in control of the Company, all outstanding options become
immediately exercisable to the extent permitted by the 1991-1992 Stock Option
Plan. All options granted to date under the 1991-1992 Stock Option Plan vest
ratably over a three-year period from their dates of grant.
 
     The Directors' Stock Option Plan permits the granting of nonqualified stock
options ("Director NQSOs") to purchase up to 200,000 shares of common stock to
nonemployee directors of the Company. Upon election as a director and annually
thereafter, each individual who serves as a nonemployee director automatically
is granted an option to purchase 10,000 shares of common stock at a price not
less than the fair market value of common stock on the date of grant. All
Director NQSOs vest automatically on the date of the grant of the options.

NOTE 10 -- RUSSIA JOINT VENTURE
 
     In December 1991, a joint venture agreement forming GEOILBENT, Limited,
between the Company and two Russian partners, Purneftegasgeologia and
Purneftegas, was approved by the appropriate regulatory bodies in Russia.
GEOILBENT's charter is to explore, develop, produce and market oil, condensate
and natural gas from the North Gubkinskoye field in the West Siberia region of
Russia, approximately two thousand miles northeast of Moscow. At the time of
GEOILBENT's formation, the field, which covers an area approximately 15 miles
long and 4 miles wide, had been delineated with over 60 wells, had been
production tested and had logged numerous oil and gas sands, but had never been
commercially produced. The joint venture agreement calls for the Company to have
a 34% working interest and the two Russian partners each to have a 33% working
interest in the joint venture. Production commenced during the third quarter of
1993.
 
     The Company is obligated under the terms of the GEOILBENT charter agreement
with its partners to make contributions of approximately $25.8 million by
December 31, 1995. At December 31, 1994, the Company's contributions totaled
approximately $19.4 million. During the first part of 1994, a combination of

development of the field by GEOILBENT. For the year ended December 31, 1994, the
Company recorded an expense for the export tariff of $1,397,317 which is
included in lease operating expenses and production taxes. In September 1994,
GEOILBENT received a recommendation from the Interdepartmental Commission of the
Ministry of Fuel and Energy for a waiver for one year from the export tariff.
Such waiver was received in March 1995, effective retroactively to January 1,
1995. The Russian regulatory environment continues to be volatile and the
Company is unable to predict the availability of the waiver during the remainder
of 1995 or for the future.
 
NOTE 11 -- VENEZUELA JOINT VENTURE
 
     On July 31, 1992, the Company and its partner, Venezolana de Inversiones y
Construcciones Clerico, C.A. ("Vinccler"), signed an operating service agreement
to reactivate and further develop three Venezuelan oil fields with Lagoven,
S.A., an affiliate of the national oil company, Petroleos de Venezuela, S.A. The
operating service agreement covers the Uracoa, Bombal and Tucupita fields that
comprise the South Monagas unit. Under the terms of the operating service
agreement, Benton-Vinccler, a corporation owned 80% by the Company and 20% by
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. Benton-Vinccler receives an operating
fee in U.S. dollars deposited into a U.S. commercial bank account for each
barrel of crude oil produced (subject to periodic adjustments to reflect changes
in a special energy index of the U.S. Consumer Price Index) and is reimbursed
according to a prescribed formula in U.S. dollars for its capital costs,
provided that such operating fee and cost recovery fee cannot exceed the maximum
dollar amount per barrel set forth in the agreement (which amount is
periodically adjusted to reflect changes in the average of certain world crude
oil prices). The Venezuelan government maintains full ownership of all
hydrocarbons in the fields.
 
     Pursuant to the original joint venture agreement, the Company and Vinccler
each owned a 50% interest in a joint venture which operated the South Monagas
unit. Effective January 1, 1994, the operating service agreement and the joint
venture assets and liabilities were transferred to Benton-Vinccler, a
corporation in which the Company and Vinccler each owned 50% of the capital
stock. On March 4, 1994, the Company acquired capital stock from Vinccler
representing an additional 30% ownership interest in Benton-Vinccler for $3
million in cash, $10 million in non-interest bearing notes payable (with a
present value of $9.2 million assuming a 10% interest rate) payable in various
installments over 24 months and 200,000 shares of the Company's common stock.
The excess of the purchase price over the book value of the 30% interest was
allocated to oil and gas properties.
 
     Prior to the acquisition of the additional 30% interest in Benton-Vinccler,
the Company's interest in the Venezuelan joint venture was proportionately
consolidated based on its ownership interest. Effective with the acquisition of
the additional 30% interest in Benton-Vinccler, the Company has included
Benton-Vinccler in its consolidated financial statements, with the 20% owned by
Vinccler reflected as a minority interest.

for the Company for the year ended December 31, 1994 and 1993 as though the
acquisition of the 30% interest had been completed and Benton-Vinccler had been

NOTE 12 -- RELATED PARTY TRANSACTIONS
 
     On December 31, 1993, the Company guaranteed a loan made to Mr. A.E.
Benton, its President and Chief Executive Officer for $300,000. In January 1994,
the Company loaned $800,000 to Mr. Benton with interest at prime plus 1% payable
in November 1995, or on demand by the Company, whichever occurs first; in
September 1994, Mr. Benton made a payment of $207,014 against this loan.
 
NOTE 13 -- EARNINGS (LOSS) PER SHARE
 
     Primary earnings per common share are computed by dividing net income
(loss) by the weighted average number of common and common equivalent shares
outstanding. Common equivalent shares are shares which may be issuable upon
exercise of outstanding stock options and warrants; however, they are not
included in the computation for the years ended December 31, 1993 and 1992,
since their effect would be to reduce the net loss per share and for the year
ended December 31, 1994, because their effect would result in dilution of less
than 3%. Total weighted average shares outstanding during the years ended
December 31, 1994, 1993 and 1992 were 24,850,922, 18,608,770 and 12,981,105,
respectively. Total weighted average common and common equivalent shares
outstanding during the three months ended March 31, 1995 and 1994 were
26,037,055 and 24,736,848, respectively
 
     Fully diluted earnings per common share are not presented since the
conversion of the Company's 8% Convertible Subordinated Notes and 8% Convertible
Subordinated Debentures would have an anti-dilutive effect.
 
NOTE 14 -- MAJOR CUSTOMERS
 
     The Company is principally involved in the business of oil and gas
exploration and production. Oil and gas purchasers that represent more than 10%
of oil and gas revenues for the year ended December 31, 1994 were Lagoven, S.A.
(67%) and Texon Corporation (10%); for the year ended December 31, 1993 were
Texon Corporation (63%) and Lagoven, S.A. (18%); and for the year ended December
31, 1992 were Plains Marketing and Transportation, Inc. formerly Sunnybrook
Transmission, Inc. (60%) and Texon Corporation (11%).

     In May 1994, the Company entered into a commodity hedge agreement designed
to reduce a portion of the Company's risk from oil price movements. Pursuant to
the hedge agreement, the Company will receive $16.82 per Bbl and will pay the
average price per Bbl of West Texas Intermediate Light Sweet Crude Oil. Such
payments will be made with respect to production of 1,000 Bbl of oil per day for
1994, 1,250 Bbl of oil per day in 1995 and 1,500 Bbl of oil per day for 1996.
During the year ended December 31, 1994, the Company incurred losses of $328,868
under the hedge agreement. The Company is exposed to credit loss in the event of
non-performance by the counterparty. The Company anticipates, however, that the
counterparty will be able to fully satisfy its obligation under the contract.
 
  Quantities of Oil and Gas Reserves (unaudited)
 
     Proved reserves are estimated quantities of crude oil, natural gas, and
natural gas liquids which geological and engineering data demonstrate with
reasonable certainty to be recoverable from known reservoirs under existing
economic and operating conditions. Proved developed reserves are those which are
expected to be recovered through existing wells with existing equipment and
operating methods. All Venezuelan reserves are attributable to an operating
service agreement between the Company and Lagoven, S.A., under which all mineral
rights are owned by the government of Venezuela. Sales of reserves in place in
1994 include reserves related to the United States properties sold in March 1995
(See Note 2).
 
     The evaluations of the oil and gas reserves as of December 31, 1992, 1993
and 1994 were audited by Huddleston & Co., Inc., independent petroleum
engineers.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     (1) The Securities and Exchange Commission requires the reserve
presentation to be calculated using year-end prices and costs and assuming a
continuation of existing economic conditions. Proved reserves cannot be measured
exactly, and the estimation of reserves involves judgmental determinations.
Reserve estimates must be reviewed and adjusted periodically to reflect
additional information gained from reservoir performance, new geological and
geophysical data and economic changes. The above estimates are based on current
technology and economic conditions, and the Company considers such estimates to
be reasonable and consistent with current knowledge of the characteristics and
extent of production. The estimates include only those amounts considered to be
Proved Reserves and do not include additional amounts which may result from new
discoveries in the future, or from application of secondary and tertiary
recovery processes where facilities are not in place.
 
     (2) Proved Developed Reserves are reserves which can be expected to be
recovered through existing wells with existing equipment and operating methods.
This classification includes:
 
          (a) Proved developed producing reserves which are reserves expected to
     be recovered through existing completion intervals now open for production
     in existing wells; and
 
          (b) Proved developed nonproducing reserves which are reserves that
     exist behind the casing of existing wells which are expected to be produced
     in the predictable future, where the cost of making such oil and gas
     available for production should be relatively small compared to the cost of
     a new well.
 
     Any reserves expected to be obtained through the application of fluid
injection or other improved recovery techniques for supplementing primary
recovery methods are included as Proved Developed Reserves only after testing by
a pilot project or after the operation of an installed program has confirmed
through production response that increased recovery will be achieved.
 
     (3) Proved Undeveloped Reserves are Proved Reserves which are expected to
be recovered from new wells on undrilled acreage or from existing wells where a
relatively major expenditure is required for recompletion. Reserves on undrilled
acreage are limited to those drilling units offsetting productive units, which
are reasonably certain of production when drilled.
 
     Proved Reserves for other undrilled units are claimed only where it can be
demonstrated with certainty that there is continuity of production from the
existing productive formation. No estimates for Proved Undeveloped Reserves are
attributable to or included in this table for any acreage for which an
application of fluid injection or other improved recovery technique is
contemplated unless proved effective by actual tests in the area and in the same
reservoir.
 
     (4) The Company's engineering estimates indicate that approximately 18 Bcf
of natural gas reserves (net to the Company's interest) will be developed and
produced in association with the development and production of the Company's
proved oil reserves in Russia. The Company expects that, due to current market
conditions, it will initially reinject or flare such associated natural gas
production, and accordingly, no future net revenue has been assigned to these
reserves. Under the joint venture agreement, such reserves are owned by the
Company in the same proportion as all other hydrocarbons in the field, and
subsequent changes in conditions could result in the assignment of value to
these reserves.
 
     (5) Changes in previous estimates of proved reserves result from new
information obtained from production history and changes in economic factors.
 
  Standardized Measure of Discounted Future Net Cash Flows Relating to Proved
Oil and Gas Reserve
  Quantities (unaudited)
 
     The standardized measure of discounted future net cash flows is presented
in accordance with the provisions of SFAS No. 69. In preparing this data,
assumptions and estimates have been used, and the Company cautions against
viewing this information as a forecast of future economic conditions.

     Future cash inflows were estimated by applying year-end prices, adjusted
for fixed and determinable escalations provided by contract, to the estimated
future production of year-end proved reserves. Future cash inflows were reduced
by estimated future production and development costs to determine pre-tax cash
inflows. Future income taxes were estimated by applying the year-end statutory
tax rates to the future pre-tax cash inflows, less the tax basis of the
properties involved, and adjusted for permanent differences and tax credits and
allowances. The resultant future net cash inflows are discounted using a ten
percent discount rate.
 
     Russia has established an export tariff on all oil produced in and exported
from Russia. GEOILBENT has received a waiver from the export tariff for 1995.
For purposes of estimating future net cash flows, the export tariff has been
applied to the Company's Russian production for the remainder of the life of the
operations after 1995, although the Company believes that additional waivers may
be obtained in the future. The discounted value of the waiver net to the
Company's interest as of December 31, 1994 was approximately $3 million.

                          INDEPENDENT AUDITORS' REPORT
 
Benton Oil & Gas Combination Partnership 1989-1, L.P.
Carpinteria, California
 
We have audited the accompanying balance sheets of Benton Oil & Gas Combination
Partnership 1989-1, L.P. as of December 31, 1994 and 1993, and the related
statements of operations, partners' capital, and cash flows for each of the
three years in the period ended December 31, 1994. These financial statements
are the responsibility of the Partnership's management. Our responsibility is to
express an opinion on these financial statements based on our audits.
 
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
In our opinion, such financial statements present fairly, in all material
respects, the financial position of Benton Oil & Gas Combination Partnership
1989-1, L.P. at December 31, 1994 and 1993, and the results of its operations
and its cash flows for each of the three years in the period ended December 31,
1994 in conformity with generally accepted accounting principles.

NOTE 1 -- ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Benton Oil & Gas Combination Partnership 1989-1, L.P. (Partnership) was
formed for the purpose of investing in oil and natural gas by acquiring proven
producing properties, recompleting previously drilled wells and developing and
drilling oil and gas wells in the state waters of Texas and offshore Louisiana.
 
     Benton Oil and Gas Company (Benton) and a wholly owned subsidiary are the
Co-Managing General Partners and as such conduct, direct and exercise full
control over all activities of the Partnership.
 
  Oil and Gas Properties
 
     Oil and gas properties are accounted for using the successful efforts
method. Under this method, costs of drilling exploratory wells are initially
capitalized pending determination of whether the well can produce proved
reserves. All costs relating to nonproductive exploratory wells are expensed.
Costs relating to productive exploratory wells and all development wells are
capitalized and depleted on a units-of-production basis over the life of the
remaining proved developed reserves. Delay rentals and geological and
geophysical costs are expensed as incurred.
 
  Organization Costs
 
     Organization costs are amortized over a period of five years using the
straight-line method.
 
  Income Taxes
 
     No provision has been made for income taxes as the liability for such taxes
is that of the partners rather than of the Partnership.
 
  Interim Reporting
 
     In the opinion of the Partnership, the accompanying unaudited consolidated
financial statements contain all adjustments (consisting of only normal
recurring accruals) necessary to present fairly the financial position as of
March 31, 1995, and the results of operations for the three month periods ended
March 31, 1995 and 1994.
 
     The results of operations for the three month period ended March 31, 1995
are not necessarily indicative of the results to be expected for the full year.
 
NOTE 2 -- PARTICIPATION IN COSTS AND REVENUES
 
     Under the terms of the Partnership agreement, the general and limited
partners (Participants) pay 99% of the lease acquisition, geophysical and
seismic costs, well costs, general and administrative expenses, and organization
and offering expenses, including commissions, while the Co-Managing General
Partners pay 1% of such costs. Revenues, production taxes and lease operating
expenses on proven producing wells are allocated 99% to the Participants and 1%
to the Co-Managing General Partners. Revenues, production taxes and lease
operating expenses on recompleted wells are allocated 74.25% to the Participants
and 25.75% to the Co-Managing General Partners. On new wells drilled, revenues,
production taxes and lease operating expenses are allocated 64.35% to the
Participants and 35.65% to the Co-Managing General Partners.
 
NOTE 3 -- RELATED PARTY TRANSACTIONS
 
     The Partnership pays the Co-Managing General Partners for general and
administrative expenses, lease operating expenses and well costs incurred on
behalf of the Partnership. Benton pays the Partnership for revenues collected on
behalf of the Partnership.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
NOTE 4 -- OIL AND GAS PROPERTIES
 
     In June 1995, the Partnership entered into an agreement to sell its
principal oil and gas properties. The sales price is subject to adjustments for
revenues, expenses and capital expenditures related to the properties until the
closing date. The agreement is subject to the approval of 75% of the partners. A
provision for impairment was made at March 31, 1995 to reflect the excess of
book value at that date over the adjusted sales price of $375,643. The adjusted
sales price has been reflected as property held for sale at March 31, 1995.
 
NOTE 5 -- COMMITMENTS AND CONTINGENCIES
 
     On June 13, 1994, certain limited partners of the Partnership, with limited
partners of other Benton partnerships, brought an action against Benton in
connection with its operation of the partnerships as managing general partner.
The parties have agreed to submit the dispute to arbitration and the lawsuit has
been dismissed. The plaintiffs seek actual and punitive damages for alleged
actions and omissions of Benton in connection with operating the partnerships
and alleged misrepresentations made by Benton in selling the limited partnership
interests. At this time, the Partnership has not been named a defendant in this
action. However, if the Partnership is added as a defendant, the Partnership
would be forced to expend financial resources to defend or resolve any such
matters. Benton does not believe that the Partnership will be adversely affected
by this action.
 
NOTE 6 -- OIL AND GAS ACTIVITIES
 
     Total costs incurred in oil and gas exploration and development were:

QUANTITIES OF OIL AND GAS RESERVES (UNAUDITED)
 
     Proved reserves are estimated quantities of crude oil, natural gas and
natural gas liquids which geological and engineering data demonstrate with
reasonable certainty to be recoverable from known reservoirs under existing
economic and operating conditions. Proved developed reserves are those which are
expected to be recovered through existing wells with existing equipment and
operating methods.
 
     The evaluations of the oil and gas reserves were prepared by J.C. White, an
independent petroleum engineer until January 1, 1993, when he became an employee
of Benton.

- ---------------
(1) The Securities and Exchange Commission requires the reserve presentation to
    be calculated using year-end prices and costs and assuming a continuation of
    existing economic conditions. Proved reserves cannot be measured exactly,
    and the estimation of reserves involves judgmental determinations. Reserve
    estimates must be reviewed and adjusted periodically to reflect additional
    information gained from reservoir performance, new geological and
    geophysical data and economic changes. The above estimates are based on
    current technology and economic conditions, and Benton considers such
    estimates to be reasonable and consistent with current knowledge of the
    characteristics and extent of production. The estimates include only those
    amounts considered to be Proved Reserves and do not include additional
    amounts which may result from new discoveries in the future, or from
    application of secondary and tertiary recovery processes where facilities
    are not in place.
 
(2) Proved Developed Reserves are reserves which can be expected to be recovered
    through existing wells with existing equipment and operating methods. This
    classification includes:
 
        (a) Proved developed producing reserves which are reserves expected to
            be recovered through existing completion intervals now open for
            production in existing wells; and
 
        (b) Proved developed nonproducing reserves which are reserves that exist
            behind the casing of existing wells which are expected to be
            produced in the predictable future, where the costs of making such
            oil and gas available for production should be relatively small
            compared to the cost of a new well.
 
            Any reserves expected to be obtained through the application of
            fluid injection or other improved recovery techniques for
            supplementing primary recovery methods are included as Proved
            Developed Reserves only after testing by a pilot project or after
            the operation of an

            installed program has confirmed through production response that
            increased recovery will be achieved.
 
(3) Proved Undeveloped Reserves are Proved Reserves which are expected to be
    recovered from new wells on undrilled acreage or from existing wells where a
    relatively major expenditure is required for recompletion. Reserves on
    undrilled acreage are limited to those drilling units offsetting productive
    units, which are reasonably certain of production when drilled.
 
     Proved Reserves for other undrilled units are claimed only where it can be
     demonstrated with certainty that there is continuity of production from the
     existing productive formation. No estimates for Proved Undeveloped Reserves
     are attributable to or included in this table for any acreage for which an
     application of fluid injection or other improved recovery technique is
     contemplated unless proved effective by actual tests in the area and in the
     same reservoir.
 
(4) Changes in previous estimates of proved reserves result from new information
    obtained from production history and changes in economic factors.
 
STANDARDIZED MEASURE OF DISCOUNTED FUTURE NET CASH FLOWS RELATING TO PROVED OIL
AND GAS RESERVE QUANTITIES (UNAUDITED)
 
     The standardized measure of discounted future net cash flows is presented
in accordance with the provisions of SFAS No. 69. In preparing this data,
assumptions and estimates have been used, and Benton cautions against viewing
this information as a forecast of future economic conditions.
 
     Future cash inflows were estimated by applying year-end prices, adjusted
for fixed and determinable escalations provided by contract, to the estimated
future production of year-end proved reserves. Future cash inflows were reduced
by estimated future production and development costs to determine pre-tax cash
inflows. The resultant future net cash inflows are discounted using a ten
percent discount rate.

We have audited the accompanying balance sheets of Benton Oil & Gas Combination
Partnership 1990-1, L.P. as of December 31, 1994 and 1993, and the related
statements of operations, partners' capital, and cash flows for each of the
three years in the period ended December 31, 1994. These financial statements
are the responsibility of the Partnership's management. Our responsibility is to
express an opinion on these financial statements based on our audits.
 
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
In our opinion, such financial statements present fairly, in all material
respects, the financial position of Benton Oil & Gas Combination Partnership
1990-1, L.P. at December 31, 1994 and 1993, and the results of its operations
and its cash flows for each of the three years in the period ended December 31,
1994 in conformity with generally accepted accounting principles.

NOTE 1 -- ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Benton Oil & Gas Combination Partnership 1990-1, L.P. (Partnership) was
formed to invest in oil and natural gas by acquiring proven producing
properties, recompleting previously drilled wells and developing and drilling
new wells.
 
     Benton Oil and Gas Company (Benton) and a wholly owned subsidiary are the
Co-Managing General Partners and as such conduct, direct and exercise full
control over all activities of the Partnership.
 
  Marketable Equity Securities
 
     Marketable equity securities are stated at the lower of aggregate cost or
market. At December 31, 1993, the cost of marketable equity securities was
$14,420 with a valuation allowance of $9,013 for an approximate market value of
$5,407. Marketable equity securities were sold in November 1994 for $7,672 for a
realized gain of $2,265.
 
  Oil and Gas Properties
 
     Oil and gas properties are accounted for using the successful efforts
method. Under this method, costs of drilling exploratory wells are initially
capitalized pending determination of whether the well can produce proved
reserves. All costs relating to nonproductive exploratory wells are expensed.
Costs relating to productive exploratory wells and all development wells are
capitalized and depleted on a units-of-production basis over the life of the
remaining proved developed reserves. Delay rentals and geological and
geophysical costs are expensed as incurred.
 
  Organization Costs
 
     Organization costs are amortized over a period of five years using the
straight-line method.
 
  Income Taxes
 
     No provision has been made for income taxes as the liability for such taxes
is that of the partners rather than of the Partnership.
 
  Interim Reporting
 
     In the opinion of the Partnership, the accompanying unaudited consolidated
financial statements contain all adjustments (consisting of only normal
recurring accruals) necessary to present fairly the financial position as of
March 31, 1995, and the results of operations for the three month periods ended
March 31, 1995 and 1994.
 
     The results of operations for the three month period ended March 31, 1995
are not necessarily indicative of the results to be expected for the full year.
 
NOTE 2 -- PARTICIPATION IN COSTS AND REVENUES
 
     Under the terms of the Partnership agreement, the general and limited
partners (Participants) pay 99% of the lease acquisition, geophysical and
seismic costs, well costs, and organization and offering expenses, including
commissions, while the Co-Managing General Partners pay 1% of such costs.
General and administrative expenses and lease operating expenses are shared
74.25% by the Participants and 25.75% by the

Co-Managing General Partners. Revenues and production taxes are allocated
73.5974% to the Participants, 25.5236% to the Co-Managing General Partners and
0.879% to broker/dealers (Special Limited Partners) who met certain minimum
sales requirements in the initial offering of the Partnership units.
 
NOTE 3 -- RELATED PARTY TRANSACTIONS
 
     The Partnership pays the Co-Managing General Partners for general and
administrative expenses, lease operating expenses and well costs incurred on
behalf of the Partnership. Benton pays the Partnership for revenues collected on
behalf of the Partnership.
 
NOTE 4 -- OIL AND GAS PROPERTIES
 
     During 1992, a provision for impairment of oil and gas properties was made
to reflect reductions in the estimated value of reserves.
 
     In April 1992, a working interest in a California well was sold. Proceeds
from the sale of the Partnership's interest were $17,881, consisting of cash and
stock of the company purchasing the well. In addition, the Partnership retained
a production payment of $8,845 to be paid from monthly net income from the well.
 
     In September 1992, the Partnership's interest in its remaining California
oil and gas wells were sold for net proceeds of $19,386.
 
     In March 1995, the Partnership sold its 0.32% working interest in certain
depths (above approximately 10,575 feet) in the West Cote Blanche Bay Field for
a purchase price of $146,900. The sales price has been reflected as property
held for sale at December 31, 1994. Impairment of $13,569 has been recorded to
reflect the anticipated loss in connection with the sale of the property.
 
     In June 1995, the Partnership entered into an agreement to sell its
principal oil and gas properties. The sales price is subject to adjustments for
revenues, expenses and capital expenditures related to the properties until the
closing date. The agreement is subject to the approval of 75% of the partners.
The adjusted sales price as of March 31, 1995 is $1,081,589 and the net book
value of the property has been reflected as property held for sale at March 31,
1995.
 
NOTE 5 -- COMMITMENTS AND CONTINGENCIES
 
     On June 13, 1994, certain limited partners of the Partnership, with limited
partners of other Benton partnerships, brought an action against Benton in
connection with its operation of the partnerships as managing general partner.
The parties have agreed to submit the dispute to arbitration and the lawsuit has
been dismissed. The plaintiffs seek actual and punitive damages for alleged
actions and omissions of Benton in connection with operating the partnerships
and alleged misrepresentations made by Benton in selling the limited partnership
interests. At this time, the Partnership has not been named a defendant in this
action. However, if the Partnership is added as a defendant, the Partnership
would be forced to expend financial resources to defend or resolve any such
matters. Benton does not believe that the Partnership will be adversely affected
by this action.

QUANTITIES OF OIL AND GAS RESERVES (UNAUDITED)
 
     Proved reserves are estimated quantities of crude oil, natural gas and
natural gas liquids which geological and engineering data demonstrate with
reasonable certainty to be recoverable from known reservoirs under existing
economic and operating conditions. Proved developed reserves are those which are
expected to be recovered through existing wells with existing equipment and
operating methods.

- ---------------
(1) The Securities and Exchange Commission requires the reserve presentation to
    be calculated using year-end prices and costs and assuming a continuation of
    existing economic conditions. Proved reserves cannot be measured exactly,
    and the estimation of reserves involves judgmental determinations. Reserve
    estimates must be reviewed and adjusted periodically to reflect additional
    information gained from reservoir performance, new geological and
    geophysical data and economic changes. The above estimates are based on
    current technology and economic conditions, and Benton considers such
    estimates to be reasonable and consistent with current knowledge of the
    characteristics and extent of production. The estimates include only those
    amounts considered to be Proved Reserves and do not include additional
    amounts which may result from new discoveries in the future, or from
    application of secondary and tertiary recovery processes where facilities
    are not in place.
 
(2) Proved Developed Reserves are reserves which can be expected to be recovered
    through existing wells with existing equipment and operating methods. This
    classification includes:
 
          (a) Proved developed producing reserves which are reserves expected to
              be recovered through existing completion intervals now open for
              production in existing wells; and
 
          (b) Proved developed nonproducing reserves which are reserves that
              exist behind the casing of existing wells which are expected to be
              produced in the predictable future, where the cost of making such
              oil and gas available for production should be relatively small
              compared to the cost of a new well.
 
              Any reserves expected to be obtained through the application of
              fluid injection or other improved recovery techniques for
              supplementing primary recovery methods are included as Proved
              Developed Reserves only after testing by a pilot project or after
              the operation of an installed program has confirmed through
              production response that increased recovery will be achieved.
 
(3) Proved Undeveloped Reserves are Proved Reserves which are expected to be
    recovered from new wells on undrilled acreage or from existing wells where a
    relatively major expenditure is required for
 
                                      F-48

    recompletion. Reserves on undrilled acreage are limited to those drilling
    units offsetting productive units, which are reasonably certain of
    production when drilled.
 
     Proved Reserves for other undrilled units are claimed only where it can be
     demonstrated with certainty that there is continuity of production from the
     existing productive formation. No estimates for Proved Undeveloped Reserves
     are attributable to or included in this table for any acreage for which an
     application of fluid injection or other improved recovery technique is
     contemplated unless proved effective by actual tests in the area and in the
     same reservoir.
 
(4) Changes in previous estimates of proved reserves result from new information
    obtained from production history and changes in economic factors. Also,
    additional production data at West Cote Blanche Bay enabled Benton to better
    conform estimates of future production to historical trends.
 
STANDARDIZED MEASURE OF DISCOUNTED FUTURE NET CASH FLOWS RELATING TO PROVED OIL
AND GAS RESERVE QUANTITIES (UNAUDITED)
 
     The standardized measure of discounted future net cash flows is presented
in accordance with the provisions of SFAS No. 69. In preparing this data,
assumptions and estimates have been used, and Benton cautions against viewing
this information as a forecast of future economic conditions.
 
     Future cash inflows were estimated by applying year-end prices, adjusted
for fixed and determinable escalations provided by contract, to the estimated
future production of year-end proved reserves. Future cash inflows were reduced
by estimated future production and development costs to determine pre-tax cash
inflows. The resultant future net cash inflows are discounted using a ten
percent discount rate.

                          INDEPENDENT AUDITORS' REPORT
 
Benton Oil & Gas Combination Partnership 1991-1, L.P.
Carpinteria, California
 
We have audited the accompanying balance sheets of Benton Oil & Gas Combination
Partnership 1991-1, L.P. as of December 31, 1994 and 1993, and the related
statements of operations, partners' capital, and cash flows for each of the
three years in the period ended December 31, 1994. These financial statements
are the responsibility of the Partnership's management. Our responsibility is to
express an opinion on these financial statements based on our audits.
 
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
In our opinion, such financial statements present fairly, in all material
respects, the financial position of Benton Oil & Gas Combination Partnership
1991-1, L.P., at December 31, 1994 and 1993, and the results of its operations
and its cash flows for each of the three years in the period ended December 31,
1994 in conformity with generally accepted accounting principles.

NOTE 1 -- ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Benton Oil & Gas Combination Partnership 1991-1, L.P. (Partnership) was
formed to invest in oil and natural gas by acquiring proven producing
properties, enhancing production of previously drilled wells and drilling new
wells.
 
     Benton Oil and Gas Company (Benton) and a wholly owned subsidiary are the
Co-Managing General Partners and as such conduct, direct and exercise full
control over all activities of the Partnership.
 
  Marketable Equity Securities
 
     Marketable equity securities are stated at the lower of aggregate cost or
market. At December 31, 1993, the cost of marketable equity securities was
$14,420 with a valuation allowance of $9,013 for an approximate market value of
$5,407. Marketable equity securities were sold in November 1994 for $7,699 for a
realized gain of $2,292.
 
  Oil and Gas Properties
 
     Oil and gas properties are accounted for using the successful efforts
method. Under this method, costs of drilling exploratory wells are initially
capitalized pending determination of whether the well can produce proved
reserves. All costs relating to nonproductive exploratory wells are expensed.
Costs relating to productive exploratory wells and all development wells are
capitalized and depleted on a units-of-production basis over the life of the
remaining proved developed reserves. Delay rentals and geological and
geophysical costs are expensed as incurred.
 
  Organization Costs
 
     Organization costs are amortized over a period of five years using the
straight-line method.
 
  Income Taxes
 
     No provision has been made for income taxes as the liability for such taxes
is that of the partners rather than of the Partnership.
 
  Interim Reporting
 
     In the opinion of the Partnership, the accompanying unaudited consolidated
financial statements contain all adjustments (consisting of only normal
recurring accruals) necessary to present fairly the financial position as of
March 31, 1995, and the results of operations for the three month periods ended
March 31, 1995 and 1994.
 
     The results of operations for the three month period ended March 31, 1995
are not necessarily indicative of the results to be expected for the full year.
 
NOTE 2 -- PARTICIPATION IN COSTS AND REVENUES
 
     Under the terms of the Partnership agreement, the general and limited
partners (Participants) pay 99% of the lease acquisition, geophysical and
seismic costs, well costs, and organization and offering expenses, including
commissions, while the Co-Managing General Partners pay 1% of such costs. For
the first twelve months of the Partnership, general and administrative expenses
are covered by a fee, equal to 3% of initial capital raised, paid by the
Partnership to Benton. The fee is paid 99% by the Participants and 1% by the Co-

Managing General Partners. General and administrative expenses after the first
twelve months and lease operating expenses are shared 74.25% by the Participants
and 25.75% by the Co-Managing General Partners. Revenues and production taxes
are allocated 73.944% to the Participants, 25.6438% to the Co-Managing General
Partners, and .4122% to broker/dealers (Special Limited Partners) who met
certain minimum sales requirements in the initial offering of the Partnership
units.
 
NOTE 3 -- RELATED PARTY TRANSACTIONS
 
     The Partnership pays the Co-Managing General Partners for syndication
costs, organization costs, general and administrative expenses, lease operating
expenses and well costs incurred on behalf of the Partnership. Benton pays the
Partnership for revenues collected on behalf of the Partnership.
 
NOTE 4 -- OIL AND GAS PROPERTIES
 
     In April 1992, a working interest in a California well was sold. Proceeds
from the sale of the Partnership's interest were $17,881 consisting of cash and
stock of the company purchasing the well. In addition, the Partnership retained
a production payment of $8,845 to be paid from monthly net income from the well.
 
     In March 1995, the Partnership sold its 0.06% working interest in certain
depths (above approximately 10,575 feet) in the West Cote Blanche Bay Field for
a purchase price of $29,200. The sales price has been reflected as property held
for sale at December 31, 1994. Impairment of $34,371 has been recorded to
reflect the anticipated loss in connection with the sale of the property.
 
     In June 1995, the Partnership entered into an agreement to sell its
principal oil and gas properties. The sales price is subject to adjustments for
revenues, expenses and capital expenditures related to the properties until the
closing date. The agreement is subject to the approval of 75% of the partners. A
provision for impairment was made at March 31, 1995 to reflect the excess of
book value at that date over the sales price of $215,280. The adjusted sales
price has been reflected as property held for sale at March 31, 1995.
 
NOTE 5 -- COMMITMENTS AND CONTINGENCIES
 
     On June 13, 1994 certain limited partners of the Partnership, with limited
partners of other Benton and partnerships, brought an action against Benton in
connection with its operation of the partnerships as managing general partner.
The parties have agreed to submit the dispute to arbitration and the lawsuit has
been dismissed. The plaintiffs seek actual and punitive damages for alleged
actions and omissions of Benton in connection with operating the partnerships
and alleged misrepresentations made by Benton in selling the limited partnership
interests. At this time, the Partnership has not been named a defendant in this
action. However, if the Partnership is added as a defendant, the Partnership
would be forced to expend financial resources to defend or resolve any such
matters. Benton does not believe that the Partnership will be adversely affected
by this action.

QUANTITIES OF OIL AND GAS RESERVES (UNAUDITED)
 
     Proved reserves are estimated quantities of crude oil, natural gas and
natural gas liquids which geological and engineering data demonstrate with
reasonable certainty to be recoverable from known reservoirs under existing
economic and operating conditions. Proved developed reserves are those which are
expected to be recovered through existing wells with existing equipment and
operating methods.

- ---------------
(1) The Securities and Exchange Commission requires the reserve presentation to
    be calculated using year-end prices and costs and assuming a continuation of
    existing economic conditions. Proved reserves cannot be measured exactly,
    and the estimation of reserves involves judgmental determinations. Reserve
    estimates must be reviewed and adjusted periodically to reflect additional
    information gained from reservoir performance, new geological and
    geophysical data and economic changes. The above estimates are based on
    current technology and economic conditions, and Benton considers such
    estimates to be reasonable and consistent with current knowledge of the
    characteristics and extent of production. The estimates include only those
    amounts considered to be Proved Reserves and do not include additional
    amounts which may result from new discoveries in the future, or from
    application of secondary and tertiary recovery processes where facilities
    are not in place.
 
(2) Proved Developed Reserves are reserves which can be expected to be recovered
    through existing wells with existing equipment and operating methods. This
    classification includes:
 
          (a) Proved developed producing reserves which are reserves expected to
              be recovered through existing completion intervals now open for
              production in existing wells; and
 
          (b) Proved developed nonproducing reserves which are reserves that
              exist behind the casing of existing wells which are expected to be
              produced in the predictable future, where the cost of making such
              oil and gas available for production should be relatively small
              compared to the cost of a new well.
 
            Any reserves expected to be obtained through the application of
            fluid injection or other improved recovery techniques for
            supplementing primary recovery methods are included as Proved
            Developed Reserves only after testing by a pilot project or after
            the operation of an installed program has confirmed through
            production response that increased recovery will be achieved.
 
(3) Proved Undeveloped Reserves are Proved Reserves which are expected to be
    recovered from new wells on undrilled acreage or from existing wells where a
    relatively major expenditure is required for

    recompletion. Reserves on undrilled acreage are limited to those drilling
    units offsetting productive units, which are reasonably certain of
    production when drilled.
 
    Proved Reserves for other undrilled units are claimed only where it can be
    demonstrated with certainty that there is continuity of production from the
    existing productive formation. No estimates for Proved Undeveloped Reserves
    are attributable to or included in this table for any acreage for which an
    application of fluid injection or other improved recovery technique is
    contemplated unless proved effective by actual tests in the area and in the
    same reservoir.
 
(4) Changes in previous estimates of proved reserves result from new information
    obtained from production history and changes in economic factors. Also,
    additional production data at West Cote Blanche Bay enabled Benton to better

AND GAS RESERVE QUANTITIES (UNAUDITED)
 
     The standardized measure of discounted future net cash flows is presented
in accordance with the provisions of SFAS No. 69. In preparing this data,
assumptions and estimates have been used, and Benton cautions against viewing
this information as a forecast of future economic conditions.
 
     Future cash inflows were estimated by applying year-end prices, adjusted
for fixed and determinable escalations provided by contract, to the estimated
future production of year-end proved reserves. Future cash inflows were reduced
by estimated future production and development costs to determine pre-tax cash
inflows. The resultant future net cash inflows are discounted using a ten
percent discount rate.

<PAGE>   206
         WARRANT AGREEMENT dated as of __________________, 1995, between Benton
Oil and Gas Company, a Delaware corporation (the "Company") and
_________________________ ("Holder").

         WHEREAS, the Company proposes to issue to the Holder common stock
purchase warrants (the "Warrants") to purchase up to ________ shares (the
"Warrant Shares") of the Company's Common Stock, par value $.01 per share (the
"Common Stock"), each Warrant entitling the holder thereof to purchase one
share of Common Stock.

         NOW, THEREFORE, in consideration of the premises and the mutual
agreements herein and in the Agreement set forth and for other good and
valuable consideration, the parties hereto agree as follows:


         1.      ISSUANCE OF WARRANTS; FORM OF WARRANT.  The Company will issue
and deliver the Warrants to Holder, in consideration for, and as part of the
compensation to Holder in connection with the sale of the assets of the
Partnership.  The number of Warrants to be issued and delivered shall be
________.  No cash consideration will be paid by Holder for the Warrants.  The
text of each Warrant, of the purchase form and of each assignment form to be
printed on the reverse thereof shall be substantially as set forth in Exhibit A
attached hereto.  The Warrants shall be executed on behalf of the Company by
the manual or facsimile signature of the present or any future Chairman of the
Board, President, Treasurer or Vice President of the Company, under its
corporate seal, affixed or in facsimile, attested by the manual or facsimile
signature of the present or future Secretary or an Assistant Secretary of the
Company.  A Warrant bearing the manual or facsimile signature of individuals
who were at any time the proper officers of the Company shall bind the Company
notwithstanding that such individuals or any of them shall have ceased to hold
such offices prior to the delivery of such Warrant or did not hold such offices
on the date of this Agreement.

         Warrants shall be dated as of the date of execution thereof by the
Company either upon initial issuance or upon division, exchange, substitution
or transfer.

         2.      REGISTRATION.    The Warrants shall be numbered and shall be
registered on the books of the Company (the "Warrant Register") as they are
issued.  The Company shall be entitled to treat the registered holder of any
Warrant on the Warrant Register (the "Holder") as the owner in fact thereof for
all purposes and shall not be bound to recognize any equitable or other claim
to or interest in such Warrant on the part of any other person, and shall not
be liable for any registration or transfer of Warrants which are registered or
to be registered in the name of a fiduciary or the nominee of a fiduciary
unless made with the actual knowledge that a fiduciary or nominee is committing
a breach of trust in                                 
                                      

                                      1





                                       
<PAGE>   207
requesting such registration or transfer, or with knowledge of such facts
that its participation therein amounts to bad faith.  The Warrants shall be
registered initially in the name of Holder in such denominations as Holder may
request in writing to the Company.


         3.      EXCHANGE OF WARRANT CERTIFICATES.   Subject to any restriction
upon transfer set forth in this Agreement, each Warrant certificate may be
exchanged at the option of the Holder thereof for another certificate or
certificates of different denominations entitling the Holder thereof to
purchase upon surrender to the Company or its duly authorized agent a like
aggregate number of Warrant Shares as the certificate or certificates
surrendered then entitle such Holder to purchase.  Any Holder desiring to
exchange a Warrant certificate or certificates shall make such request in
writing delivered to the Company, and shall surrender, properly endorsed, the
certificate or certificates to be so exchanged.  Thereupon, the Company shall
execute and deliver to the person entitled thereto a new Warrant certificate or
certificates, as the case may be, as so requested.  Any Warrant issued upon
exchange, transfer or partial exercise of the Warrants shall be the valid
obligation of the Company, evidencing the same generic rights and entitled to
the same generic benefits under this Agreement as the Warrants surrendered for
such exchange, transfer or exercise.

         4.      TERM OF WARRANTS; EXERCISE OF WARRANTS.

                 (a) Each Warrant entitles the Holder thereof to purchase one
         share of Common Stock subject to adjustment in accordance with Section
         9 hereof at any time from 9:00 A.M., Los Angeles time, 
         on __________________, 1995 until 5:00 P.M., Los Angeles time, 
         on _________________, 1998 (the "Expiration Date") at a purchase 
         price of $_________ per share.

                 (b)      The Warrant Price and the number of shares issuable
         upon exercise of Warrants are subject to adjustment upon the
         occurrence of certain events, pursuant to the provisions of Section 9
         of this Agreement.  Subject to the provisions of this Agreement, each
         Holder shall have the right, which may be exercised as expressed in
         such Warrants, to purchase from the Company (and the Company shall
         issue and sell to such Holder) the number of fully paid and
         nonassessable shares of Common Stock specified in such Warrants, upon
         surrender to the Company, or its duly authorized agent, of such
         Warrants, with the purchase form on the reverse thereof duly filled in
         and signed, and upon payment to the Company of the Warrant Price, as
         adjusted in accordance with the provisions of Section 8 of this
         Agreement, for the number of shares in respect of which such 
         Warrants are then exercised.  Payment of such Warrant Price may be
         made only in cash, or by certified or official bank check.

                                      2
<PAGE>   208

         Upon such surrender of Warrants, and payment of the Warrant Price as
aforesaid, the Company shall issue and cause to be delivered with all
reasonable dispatch to or upon the written order of the Holder and (subject to
receipt of evidence of compliance with the Act in accordance with the
provisions of Section 11 of this Agreement) in such name or names as the Holder
may designate, a certificate or certificates for the number of full shares of
Common Stock so purchased upon the exercise of such Warrants, together with
cash, as provided in Section 10 of this Agreement, in respect of any fraction
of a share of such stock otherwise issuable upon such surrender.  Such
certificate or certificates shall be deemed to have been issued and any person
so designated to be named therein shall be deemed to have become a holder of
record of such shares as of the date of the surrender of such Warrants and
payment of the Warrant Price as aforesaid; PROVIDED, HOWEVER, that if, at the
time of surrender of the Warrant and payment of such Warrant Price, the
transfer books for the Common Stock or other class of stock purchasable upon
the exercise of the Warrants shall be closed, the certificates for the shares
in respect of which the Warrants are then exercised shall be issuable as of the
date on which such books shall next be opened whether before, on or after the
Expiration Date and until such date the Company shall be under no duty to
deliver any certificate for such shares; PROVIDED, FURTHER, however, that the
transfer books shall not be closed at any one time for a period longer than
five days unless otherwise required by law.  The rights of purchase represented
by the Warrants shall be exercisable, at the election of the Holders thereof,
either in full or from time to time in part and, in the event that any Warrant
is exercised in respect of less than all of the shares purchasable on such
exercise at any time prior to the Expiration Date, a new certificate evidencing
the remaining Warrant or Warrants will be issued.


         4.1.    COMPLIANCE WITH GOVERNMENT REGULATIONS.  The Company covenants
that if any shares of Common Stock required to be reserved for purposes of
exercise or conversion of Warrants require, under any Federal or state law or
applicable governing rule or regulation of any national securities exchange,
registration with or approval of any governmental authority, or listing on any
such national securities exchange, before such shares may be issued upon
exercise, the Company will in good faith and as expeditiously as possible
endeavor to cause such shares to be duly registered, approved or listed on the
relevant national securities exchange, as the case may be, PROVIDED, HOWEVER,
that in no event shall such shares of Common Stock be issued, and the Company
is hereby authorized to suspend the exercise of all Warrants, for the period
during which such registration, approval or listing is required but not in
effect.





                                      3
<PAGE>   209

         5.      PAYMENT OF TAXES.  The Company will pay all documentary stamp
taxes, if any, attributable to the initial issuance of Warrant Shares upon the
exercise of Warrants and any securities issued pursuant to Section 8 hereof;
PROVIDED, HOWEVER, that the Company shall not be required to pay any tax or
taxes which may be payable in respect of any transfer involved in the issue or
delivery of any Warrants or certificates for Warrant Shares and any securities
issued pursuant to Section 8 hereof in a name other than that of the Holder of
such Warrants.


         6.      MUTILATED OR MISSING WARRANTS.  In case any of the Warrants
shall be mutilated, lost, stolen or destroyed, the Company may in its
discretion issue and deliver in exchange and substitution for and upon
cancellation of the mutilated Warrant, or in lieu of and in substitution for
the Warrant lost, stolen or destroyed, a new Warrant of like tenor and
representing an equivalent right or interest; but only upon receipt of evidence
reasonably satisfactory to the Company of such loss, theft or destruction of
such Warrant and indemnity or bond, if requested, also reasonably satisfactory
to the Company.  An applicant for such substitute Warrants shall also comply
with such other reasonable regulations and pay such other reasonable charges as
the Company may prescribe.


         7.      RESERVATION OF WARRANT SHARES; PURCHASE AND CANCELLATION OF
WARRANTS.  There have been reserved out of the authorized and unissued shares
of Common Stock, a number of shares sufficient to provide for the exercise of
the rights of purchase represented by the Warrants, and the transfer agent for
the Common Stock ("Transfer Agent") and every subsequent transfer agent for any
shares of the Company's capital stock issuable upon the exercise of any of the
rights of purchase aforesaid are hereby irrevocably authorized and directed at
all times until the Expiration Date to reserve such number of authorized and
unissued shares as shall be requisite for such purpose.  The Company will keep
a copy of this Agreement on file with the Transfer Agent and with every
subsequent transfer agent for any shares of the Company's capital stock
issuable upon the exercise of the rights of purchase represented by the
Warrants.  The Company will supply the Transfer Agent and any such subsequent
transfer agent with duly executed stock certificates for such purpose and will
itself provide or otherwise make available any cash which may be issuable as
provided in Section 9 of this Agreement.  The Company will furnish to the
Transfer Agent and any such subsequent transfer agent a copy of all notices of
adjustments, and certificates related thereto, transmitted to each Holder
pursuant to Section 9.3 hereof.  All Warrants surrendered in the exercise of
the rights thereby evidenced shall be cancelled, and such cancelled Warrants 
shall constitute sufficient evidence of the number of shares
of stock which have been issued upon the exercise of such Warrants (subject


                                      4
<PAGE>   210
to adjustment as herein provided).  No shares of stock shall be subject to
reservation in respect of the Warrants subsequent to the Expiration Date except
to the extent necessary to comply with the terms of this Agreement.


         8.      ADJUSTMENT OF WARRANT PRICE AND NUMBER OF WARRANT SHARES.  The
number and kind of securities purchasable upon the exercise of each Warrant and
the Warrant Price shall be subject to adjustment from time to time upon the
occurrence of certain events, as hereafter defined.


         8.1.    MECHANICAL ADJUSTMENTS.  The number of Warrant Shares
purchasable upon the exercise of each Warrant and the Warrant Price shall be
subject to adjustment as follows:

                 (a)      In case the Company shall (i) pay a dividend in
         shares of Common Stock or make a distribution in shares of Common
         Stock, (ii) subdivide its outstanding shares of Common Stock, (iii)
         combine its outstanding shares of Common Stock into a smaller number
         of shares of Common Stock or (iv) issue by reclassification of its
         shares of Common Stock other securities of the Company (including any
         such reclassification in connection with a consolidation or merger in
         which the Company is the surviving corporation), the number of Warrant
         Shares purchasable upon exercise of each Warrant immediately prior
         thereto shall be adjusted so that the Holder of each Warrant shall be
         entitled to receive the kind and number of Warrant Shares or other
         securities of the Company which he would have owned or have been
         entitled to receive after the happening of any of the events described
         above, had such Warrant been exercised immediately prior to the
         happening of such event or any record date with respect thereto
         regardless of whether the Warrants are exercisable at the time of the
         happening of such event or at the time of any record date with respect
         thereto.  An adjustment made pursuant to this paragraph (a) shall
         become effective immediately after the effective date of such event
         retroactive to the record date, if any, for such event.

                 (b)      In case the Company shall issue rights, options or
         warrants to all holders of its outstanding Common Stock, without any
         charge to such holders, entitling them (for a period expiring within
         60 days after the record date mentioned below) to subscribe for or
         purchase shares of Common Stock at a price per share which is lower at
         the record date mentioned below than the then current market price per
         share of Common Stock (as determined in accordance with paragraph (e)
         below), the number of Warrant Shares thereafter purchasable upon the
         exercise of each Warrant shall be determined by multiplying the 
         number of Warrant Shares theretofore purchasable upon





                                      5

<PAGE>   211
         exercise of each Warrant by a fraction, of which the numerator
         shall be the number of shares of Common Stock outstanding on the date
         of issuance of such rights, options or warrants plus the number of
         additional shares of Common Stock offered for subscription or
         purchase, and of which the denominator shall be the number of shares
         of Common Stock outstanding on the date of issuance of such rights,
         options or warrants plus the number of shares which the aggregate
         offering price of the total number of shares of common stock so
         offered would purchase at the current market price per share of Common
         Stock at such record date.  Such adjustment shall be made whenever
         such rights, options or warrants are issued, and shall become
         effective immediately after the record date for the determination of
         stockholders entitled to receive such rights, options or warrants.

                 (c)      In case the Company shall distribute to all holders
         of its shares of Common Stock evidences of its indebtedness or assets
         (excluding cash dividends or distributions payable out of consolidated
         earnings or earned surplus and dividends or distributions referred to
         in paragraph (a) above or in the paragraph immediately following this
         paragraph) or rights, options or warrants, or convertible or
         exchangeable securities containing the right to subscribe for or
         purchase shares of Common Stock (excluding those referred to in
         paragraph (b) above), then in each case the number of Warrant Shares
         thereafter purchasable upon the exercise of each Warrant shall be
         determined by multiplying the number of Warrant Shares theretofore
         purchasable upon the exercise of each Warrant by a fraction, of which
         the numerator shall be the then current market price per share of
         Common Stock (as determined in accordance with paragraph (e) below) on
         the date of such distribution, and of which the denominator shall be
         the then current market price per share of Common Stock, less the then
         fair value (as determined in good faith by the Board of Directors of
         the Company, whose determination shall be conclusive) of the portion
         of the assets or evidences of indebtedness so distributed or of such
         subscription rights, options or warrants, or of such convertible or
         exchangeable securities applicable to one share of Common Stock.  Such
         adjustment shall be made whenever any such distribution is made, and
         shall become effective on the date of distribution retroactive to the
         record date for the determination of stockholders entitled to receive
         such distribution.

                 In the event of distribution by the Company to all holders of
         its shares of Common Stock of stock of a subsidiary or securities
         convertible into or exercisable for such stock, then in lieu of an
         adjustment in the number of Warrant Shares purchasable upon the
         exercise of each Warrant, the Holder of each Warrant, upon the
         exercise thereof at any time after such distribution, shall be 
         entitled to receive from the Company,

                                      6
<PAGE>   212
         such subsidiary or both, as the Company shall determine, the
         stock or other securities to which such Holder would have been
         entitled if such Holder had exercised such Warrant immediately prior
         thereto regardless of whether the Warrants are exercisable at such
         time, all subject to further adjustment as provided in this subsection
         8.1; PROVIDED, HOWEVER, that no adjustment in respect of dividends or
         interest on such stock or other securities shall be made during the
         term of a Warrant or upon the exercise of a Warrant.

                 (d)      In case the Company shall sell and issue shares of
         Common Stock (other than pursuant to rights, options, warrants, or
         convertible securities initially issued before the date of this
         Agreement) or rights, options, warrants or convertible securities
         containing the right to subscribe for or purchase shares of Common
         Stock (excluding shares, rights, options, warrants or convertible
         securities issued in any of the transactions described in paragraphs
         (a), (b) or (c) above) at a price per share of Common Stock
         (determined, in the case of such rights, options, warrants or
         convertible securities, by dividing (w) the total of the amount
         received or receivable by the Company (determined as provided below)
         in consideration of the sale and issuance of such rights, options,
         warrants or convertible securities, by (x) the total number of shares
         of Common Stock covered by such rights, options, warrants or
         convertible securities) lower than the then current market price per
         share of Common Stock (as determined in accordance with paragraph (e)
         below) in effect immediately prior to such sale and issuance, then the
         number of Warrant Shares thereafter purchasable upon the exercise of
         the Warrants shall be determined by multiplying the number of Warrant
         Shares theretofore purchasable upon exercise by a fraction, of which
         the numerator shall be the number of shares of Common Stock
         outstanding on the date of issuance of such shares, rights, options,
         warrants or convertible securities plus the number of additional
         shares of Common Stock sold or subject to issuance pursuant to such
         rights, options, warrants or convertible securities, and of which the
         denominator shall be the number of shares of Common Stock outstanding
         on the date of issuance of such shares, rights, options, warrants or
         convertible securities plus the number of shares of Common Stock which
         the aggregate consideration received or receivable (determined as
         provided below) for such sale or issuance would purchase at such
         current market price per share.  Such adjustment shall be made
         successively whenever such an issuance is made.  For the purposes of
         such adjustments, the consideration received or receivable by the
         Company for rights, options, warrants or convertible securities shall
         be deemed to be the consideration received by the Company for such
         rights, options, warrants or convertible securities, plus the
         consideration or premiums stated in such rights,
         options, warrants or convertible securities to be paid for the shares





                                      
                                      7

         of Common Stock covered thereby.  In case the Company shall
         sell and issue shares of Common Stock, or rights, options, warrants or
         convertible securities containing the right to subscribe for or
         purchase shares of Common Stock, for a consideration consisting, in
         whole or in part, of property other than cash or its equivalent, then
         in determining the "price per share of Common Stock" and the
         "consideration received or receivable by the Company" for purposes of
         the first sentence of this paragraph (d), the Board of Directors shall
         determine, in its discretion, the fair value of said property, and
         such determination, if made in good faith, shall be binding upon all
         Holders.

                (e)      For the purpose of any computation under paragraphs
         (b), (c) and (d) of this Section, the current market price per share
         of Common Stock at any date shall be the daily closing price of the
         Company's Common Stock, as reported by the American Stock Exchange.
         The closing price for such day shall be the last such reported sales
         price regular way or, in case no such reported sale takes place on
         such day, the average of the closing bid and asked prices regular way
         for such day, in each case on the principal national securities
         exchange on which the shares of Common Stock are listed or admitted to
         trading or, if not listed or admitted to trading, the average of the
         closing bid and asked prices of the Common Stock in the
         over-the-counter market as reported by NASDAQ or any comparable
         system.  In the absence of one or more such quotations, the Board of
         Directors of the Company shall determine the current market price, in
         good faith, on the basis of such quotations as it considers
         appropriate.  Notwithstanding the foregoing, for the purpose of any
         calculation under paragraph (d) above (A) with respect to any issuance
         of options under the Company's employee or director compensation stock
         option plans as in effect or as adopted by the Board of Directors of
         the Company on the date hereof, the term "current market price" in
         such instances shall mean the fair market price on the date of the
         issuance of any such option determined in accordance with the
         Company's employee compensation stock option plans as in effect or as
         adopted by the Board of Directors of the Company on the date hereof;
         (B) with respect to any issuances of Common Stock (or rights, options,
         warrants or convertible securities containing the right to subscribe
         for or purchase shares of Common Stock) in connection with bona fide
         corporate transactions (other than issuances in such transactions for
         cash or similar consideration), the term "fair market price" shall
         mean the fair market price per share as determined in arm's-length
         negotiations by the Company and such other parties (other than
         affiliates or subsidiaries of the Company) to such transactions as
         reflected in the definitive documentation with respect thereto, unless
         such reasonably related to the closing market price on the date of
         such





                                      8
<PAGE>   214
         determination; and (c) with respect to any issuance of the
         Company's common stock for cash or similar consideration in a firm
         commitment underwriting, the current fair market price shall be the
         price the shares are sold at, regardless of whether such price is
         higher or lower than the quoted price on the date of the sale and
         therefore no adjustment will be made.

                (f)      In any case in which this Section 8.1 shall require
         that any adjustment in the number of Warrant Shares be made effective
         as of immediately after a record date for a specified event, the
         Company may elect to defer until the occurrence of the event the
         issuing to the Holder of any Warrant exercised after that record date
         the shares of Common Stock and other securities of the Company, if
         any, issuable upon the exercise of any Warrant over and above the
         shares of Common Stock and other securities of the Company, if any,
         issuable upon the exercise of any Warrant prior to such adjustment;
         PROVIDED, HOWEVER, that the Company shall deliver to the holder a due
         bill or other appropriate instrument evidencing the holder's right to
         receive such additional shares or securities upon the occurrence of
         the event requiring such adjustment.

                (g)      No adjustment in the number of Warrant Shares
         purchasable hereunder shall be required unless such adjustment would
         require an increase or decrease of at least one percent (1%) in the
         number of Warrant Shares purchasable upon the exercise of each
         Warrant; PROVIDED, HOWEVER, that any adjustments which by reason of
         this paragraph (g) are not required to be made shall be carried
         forward and taken into account in any subsequent adjustment.  All
         calculations shall be made to the nearest one-thousandth of a share.

                (h)      Whenever the number of Warrant Shares purchasable upon
         the exercise of each Warrant is adjusted, as herein provided, the
         Warrant Price payable upon the exercise of each Warrant shall be
         adjusted by multiplying such Warrant Price immediately prior to such
         adjustment by a fraction, of which the numerator shall be the number
         of Warrant Shares purchasable upon the exercise of such Warrant
         immediately prior to such adjustment, and of which the denominator
         shall be the number of Warrant Shares purchasable immediately
         thereafter.

                (i)      No adjustment in the number of Warrant Shares
         purchasable upon the exercise of each Warrant need be made under
         paragraphs (b), (c) and (d) if the Company issues or distributes to
         each Holder of Warrants the rights, options, warrants, or convertible
         or exchangeable securities, or evidences of indebtedness or assets
         referred to in those paragraphs which each Holder of Warrants would
         have been 



                                      9
<PAGE>   215
         entitled to receive had the Warrants been exercised prior to
         the happening of such event or the record date with respect thereto
         regardless of whether the Warrants are exercisable at the time of the
         happening of such event or at the time of any record date with respect
         thereto.  No adjustment need be made for a change in the par value of
         the Warrant Shares.

                (j)      For the purpose of this Section 8.1, the term "shares
         of Common Stock" shall mean (i) the class of stock designated as the
         Common Stock of the Company at the date of this Agreement, or (ii) any
         other class of stock resulting from successive changes or
         reclassifications of such shares consisting solely of changes in par
         value, or from par value to no par value, or from no par value to par
         value.  In the event that at any time, as a result of an adjustment
         made pursuant to paragraph (a) above, the Holders shall become
         entitled to purchase any securities of the Company other than shares
         of Common Stock, thereafter the number of such other securities so
         purchasable upon exercise of each Warrant and the Warrant Price of
         such securities shall be subject to adjustment from time to time in a
         manner and on terms as nearly equivalent as practicable to the
         provisions with respect to the Warrant Shares contained in paragraphs
         (a) through (i), inclusive, above, and the provisions of Section 5 and
         Sections 8.2 through 8.5, inclusive, with respect to the Warrant
         Shares, shall apply on like terms to any such other securities.

                (k)      Upon the expiration of any rights, options, warrants
         or conversion or exchange privileges, if any thereof shall not have
         been exercised, the Warrant Price and the number of shares of Common
         Stock purchasable upon the exercise of each Warrant shall, upon such
         expiration, be readjusted and shall thereafter be such as it would
         have been had it been originally adjusted (or had the original
         adjustment not been required, as the case may be) as if (A) the only
         shares of Common Stock so issued were the shares of Common Stock, if
         any, actually issued or sold upon the exercise of such rights,
         options, warrants or conversion or exchange rights and (B) such shares
         of Common Stock, if any, were issued or sold for the consideration
         actually received by the Company upon such exercise plus the aggregate
         consideration, if any, actually received by the Company for the
         issuance, sale or grant of all such rights, options, warrants or
         conversion or exchange rights whether or not exercised; PROVIDED,
         HOWEVER, that no such readjustment shall have the effect of increasing
         the Warrant Price or decreasing the number of Warrant Shares by an
         amount in excess of the amount of the adjustment initially made with
         respect to the issuance, sale or grant of such rights, options,
         warrants or conversion or exchange rights.

         8.2.    VOLUNTARY ADJUSTMENT BY THE COMPANY.  The Company may, at its
option, at any time during the term of the Warrants, reduce the then current
Warrant Price to any amount determined appropriate by the Board of Directors of
the Company.


         8.3.    NOTICE OF ADJUSTMENT.  Whenever the number of Warrant Shares
purchasable upon the exercise of each Warrant or the Warrant Price of such
Warrant Shares is adjusted, as herein provided, the Company shall promptly mail
by first class, postage prepaid, to each Holder notice of such adjustment or
adjustments and a certificate of a firm of independent public accountants
selected by the Board of Directors of the Company (who may be the regular
accountants employed by the Company) setting forth the number of Warrant Shares
purchasable upon the exercise of each Warrant and the Warrant Price of such
Warrant Shares after such adjustment and setting forth a brief statement of the
facts requiring such adjustment and setting forth the computation by which such
adjustment was made.  Such certificate, absent manifest error, shall be
conclusive evidence of the correctness of such adjustment.


         8.4.    NO ADJUSTMENT FOR DIVIDENDS.  Except as provided in Section
8.1, no adjustment in respect of any dividends shall be made during the term of
a Warrant or upon the exercise of a Warrant.


         8.5.    PRESERVATION OF PURCHASE RIGHTS UPON MERGER, CONSOLIDATION,
ETC.  In case of any consolidation of the Company with or merger of the Company
into another corporation or in case of any sale, transfer or lease to another
corporation of all or substantially all the property of the Company, the
Company or such successor or purchasing corporation, as the case may be, shall
execute with each Holder an agreement that each Holder shall have the right
thereafter upon payment of the Warrant Price in effect immediately prior to
such action to purchase upon exercise of each Warrant the kind and amount of
shares and other securities and property which he would have owned or have been
entitled to receive after the happening of such consolidation, merger, sale,
transfer or lease had such Warrant been exercised immediately prior to such
action regardless of whether the Warrants are exercisable at the time of such
action; PROVIDED, HOWEVER, that no adjustment in respect of dividends, interest
or other income on or from such shares or other securities and property shall
be made during the term of a Warrant or upon the exercise of a Warrant.  Such
agreement shall provide for adjustments, which shall be as nearly equivalent as
may be practicable to the adjustments provided for in this Section 8.
The provisions of this Section 8.5 shall similarly apply to successive
consolidations, mergers, sales, transfers or leases.





                                      11
<PAGE>   217

         8.6.    STATEMENT ON WARRANTS.  Irrespective of any adjustments in the
Warrant Price or the number or kind of shares purchasable upon the exercise of
the Warrants, Warrants theretofore or thereafter issued may continue to express
the same price and number and kind of shares as are stated in the Warrants
initially issuable pursuant to this Agreement.


         9.      FRACTIONAL INTERESTS.  The Company shall not be required to
issue fractional Warrant Shares on the exercise of Warrants.  If more than one
Warrant shall be presented for exercise in full at the same time by the same
Holder, the number of full Warrant Shares which shall be issuable upon the
exercise thereof shall be computed on the basis of the aggregate number of
Warrant Shares purchasable on exercise of the Warrants so presented.  If any
fraction of a Warrant Share would, except for the provisions of this Section 9,
be issuable on the exercise of any Warrant (or specified portion thereof), the
Company shall pay an amount in cash equal to the closing price for one share of
the Common Stock, as determined in accordance with paragraph (e) of Section
8.1, on the trading day immediately preceding the date the Warrant is presented
for exercise, multiplied by such fraction.


         10.     REGISTRATION UNDER THE SECURITIES ACT OF 1933.  Holder
represents and warrants to the Company that Holder will not dispose of any such
Warrants or Warrant Shares except pursuant to (i) an effective registration
statement, or (ii) an applicable exemption from registration under the
Securities Act of 1933 (the "Act").  In connection with any sale by Holder
pursuant to clause (ii) of the preceding sentence, Holder shall furnish to the
Company an opinion of counsel reasonably satisfactory to the Company to the
effect that such exemption from registration is available in connection with
such sale.

         11.     NO RIGHTS AS STOCKHOLDERS; NOTICE TO HOLDERS.  Nothing
contained in this Agreement or in any of the Warrants shall be construed as
conferring upon the Holders or their transferees the right to vote or to
receive dividends or to consent or to receive notice as stockholders in respect
of any meeting of stockholders for the election of directors of the Company or
any other matter, or any rights whatsoever as stockholders of the Company.  If,
however, at any time prior to the expiration of the Warrants and prior to their
exercise, any of the following events shall occur:

                 (a)      the Company shall declare any dividend payable in any
         securities upon its shares of Common Stock or make any distribution
         (other than a cash dividend) to the holders of its shares of Common
         Stock; or




                                      12
<PAGE>   218


                 (b)      the Company shall offer to the holders of its shares
         of Common Stock any additional shares of Common Stock or securities
         convertible into or exchangeable for shares of Common Stock or any
         right to subscribe to or purchase any thereof; or

                 (c)      a dissolution, liquidation or winding up of the
         Company (other than in connection with a consolidation, merger, sale,
         transfer or lease of all or substantially all of its property, assets,
         and business as an entirety) shall be proposed,

then in any one or more of said events the Company shall (a) give notice in
writing of such event to the Holders as provided in Section 15 hereof and (b)
if there are more than 100 Holders, cause notice of such event to be published
once in The Wall Street Journal (national edition), such giving of notice and
publication to be completed at least 15 days prior to the date fixed as a
record date or the date of closing the transfer books for the determination of
the stockholders entitled to such dividend, distribution, or subscription
rights, or for the determination of stockholders entitled to vote on such
proposed dissolution, liquidation or winding up.  Such notice shall specify
such record date or the date of closing the transfer books, as the case may be.
Failure to publish, mail or receive such notice or any defect therein or in the
publication or mailing thereof shall not affect the validity of any action
taken in connection with such dividend, distribution or subscription rights, or
such proposed dissolution, liquidation or winding up.


         12.     NOTICES.  Any notice pursuant to this Agreement to be given or
made by the Holder of any Warrant or Warrant Shares to or on the Company shall
be sufficiently given or made if sent by first-class mail, postage prepaid,
addressed as follows:

<PAGE>   219
         13.     GOVERNING LAW.  This Agreement shall be governed by and
construed in accordance with the laws of the State of California, without
giving effect to principles of conflict of laws.


         14.     SUPPLEMENTS AND AMENDMENTS.       The Company and the Holders
may from time to time supplement or amend this Agreement in order to cure any
ambiguity or to correct or supplement any provision contained herein which may
be defective or inconsistent with any other provision herein, or to make any
other provisions in regard to matters or questions arising hereunder which the
Company and the Holder may deem necessary or desirable and which shall not be
inconsistent with the provisions of the Warrants and which shall not adversely
affect the interests of the Holders.  Any amendment to this Agreement may be
effected with the consent of Holders of at least 66 2/3% of the Warrants (for
this purpose Warrant Shares shall be deemed to be Warrants in the proportion
that Warrant Shares are then issuable upon the exercise of Warrants); provided
that, any amendment which shall have the effect of materially adversely
affecting the interests of any Holder shall not be effective with respect to
such Holder if such Holder shall not have consented thereto.


         15.     SUCCESSORS.      All the covenants and provisions of this
Agreement by or for the benefit of the Company or the Holders shall bind and
inure to the benefit of their respective successors and assigns hereunder.


         16.     MERGER OR CONSOLIDATION OF THE COMPANY.    So long as this
Agreement remains in effect, the Company will not merge or consolidate with or
into, or sell, transfer or lease all or substantially all of its property to,
any other corporation unless the successor or purchasing corporation, as the
case may be (if not the Company), shall expressly assume, by supplemental
agreement executed and delivered to the Holders, the due and punctual
performance and observance of each and every covenant and condition of this
Agreement to be performed and observed by the Company.


         17.     BENEFITS OF THIS AGREEMENT.       Nothing in this Agreement
shall be construed to give to any person or corporation other than the Company
and the Holders, any legal or equitable right, remedy or claim under this
Agreement, but this Agreement shall be for the sole and exclusive benefit of
the Company and the Holders of the Warrants and Warrant Shares.

         18.     CAPTIONS.        The captions of the sections and subsections
of this Agreement have been inserted for convenience and shall have no
substantive effect.

         19.     COUNTERPARTS.    This Agreement may be executed in any number
of counterparts, each of which so executed shall be deemed to be an original;

                                             Estimated Reserves and Revenues As 
                                             of January 1, 1995

Dear Mr. Benton:

Pursuant to your request, we have audited estimates of future reserves and
associated revenues for certain properties owned by the Benton Oil & Gas
Combination Partnership 1989-1 L.P. (the Partnership).  These projections were
originally prepared by the Benton Oil and Gas Company (Benton) engineering
staff and have been audited by Huddleston & Co., Inc. (Huddleston).  Properties
reviewed in detail by our firm for the purposes of this audit include Umbrella

REPORTING REQUIREMENTS
- ----------------------

Securities and Exchange Commission (SEC) Regulation S-K, Item 102 and
REgulation S-X, Rule 4-10 and Financial Accounting Standards Board (FASB)
Statement No. 69 require oil and gas reserve information to be reported by
publicly held entities as supplemental financial data.  These regulations and
standards provide for estimates of Proved reserves and associated revenues
discounted at 10% based on product prices being received on the effective date
of the report.

The Society of Petroleum Engineers (SPE) requires Proved reserves to be
economically recoverable with costs and prices in effect on the "as of" date of
the report.  In addition, the SPE has issued Standards Pertaining to the
Estimating and Auditing of Oil and Gas Reserve Information which sets standards
for the qualification and independence of reserve estimators and auditors and
accepted methods for estimating and scheduling future reserves.  

In our opinion, both the audit performed by huddleston and the estimates
prepared by Benton have been performed in accordance with all applicable SEC,
FASB, and SPE regulations and requirements.  It should be noted that the
reserve estimates shown herein are consistent with estimates prepared by Benton
as of January 1, 1995.
        
REPORT PREPARATION
- ------------------

The estimated reserves and revenues provided for this review were initially
prepared by Benton and have been reviewed in detail by our firm for the
purposes of this audit.  Where there were significant differences in the
estimated reserves and revenues, Huddleston has suggested revisions in the
Benton estimates and Benton has revised its projections accordingly.  In our
opinion, estimates for the properties, individually and in aggregate, are not
materially different from those which would have been rendered by Huddleston
had we independently projected the reserve volumes.

In performing our audit we have utilized certain geological and petrophysical
studies which were prepared by Benton and representatives of the current and
previous operators.  We have reviewed these studies and have found them to be
reasonable with respect to the subject reservoirs; however, we have not
attempted to independently prepare geological interpretations or estimates of
reservoir parameters.  In some cases we have utilized information from our
files relating to previous studies of certain properties shown herein.

The projections which were reviewed for the purposes of this audit represent
100% of the total future revenues as projected by Benton.  Huddleston has not
attempted to review projections for the remaining properties in detail;
however, these properties have not been assigned any future reserves.  We do
not believe that a review of these properties would result in a material
revision of the total estimated reserves and revenues.

The projections shown herein were based on performance data from public sources
available in June 1994; however, data of this type is subject to delays as a
result of regulatory reporting requirements and the timing of the commercial
sources providing such data.

The cash flow projections were prepared utilizing a commercially available
software package marketed by David P. Cook & Associates.  We have generally
reviewed the output of the calculation procedures utilized by the program and
believe them to be mathematically correct for the purposes of this audit.

PRODUCT PRICES
- --------------

It is our understanding that SEC regulations require future revenues to be
projected on the basis of product prices in effect on the "as of" date of the
report without further escalations or reductions.  However, certain variations
in product prices, attributable to contractual provisions, may be utilized in
the preparation of the cash flows where the prices are specified by the
contract.

The projections shown herein have been based on actual prices being received on
December 31, 1994.  These prices were held constant over the life of the
properties.

Market prices for both oil and gas continue to be subject to a significant
degree of variation in both domestic and international markets and reductions
in the market prices for oil volumes have materially affected the value of our
previous reserve estimates.

A comparison of the average product prices, weighted as a composite for all
properties, is as follows:

The estimated reserves and revenues have been projected on a calendar year
basis with the first time period being January 1, 1995, through December 31,
1995.


RESERVES ESTIMATES
- ------------------

Reserve estimates for the properties reviewed for the purpose of this audit
have been prepared with consideration of the available data and the nature of
the producing horizons.  The projections have been based on performance data
for the existing completions, analogy to other completions in the subject
reservoirs, and volumetric calculations.  Estimates prepared on the basis of
analogy and volumetric calculations will be subject to much greater variation
than those prepared for depletion drive reservoirs having established
production trends.

UMBRELLA POINT FIELD - This property operated by French Production,
Incorporated, is located in state waters offshore Chambers County, Texas, and
produces from multiple reservoirs.  Projections for this property were based
primarily on the extrapolation of production data with consideration for water
cut and pressure information, where available.  We have also utilized
information from our files from previous studies prepared by our firm relating
to this property.  In general, the productive reservoirs for this property are
in the latter stages of depletion and future recoveries may be influenced by
both mechanical and reservoir factors.

OTHER PROPERTIES - We have not attempted to independently prepare estimates of
future reserves for the remaining properties located in East Cameron Block 229
Field; however, we have reviewed the projections with consideration for
historical production levels.  The Benton estimates are consistent with recent
performance and Benton has projected that the properties do not have any future
economically recoverable reserves.

GENERAL CONCLUSIONS - On an overall basis, we have not encountered materials
differences in our reserve estimates and those prepared by Benton.  However,
the projected reserves shown herein have been extracted from the total Benton
report and represent minor values relative to all properties owned by Benton.
The properties shown have therefore been studied to a much lesser extent than
if reserves had been prepared separately.  In cases where we have encountered
significant differences in estimated recoveries, Benton has consented to the
revision of its reserve estimates to be consistent with projections by
Huddleston.

The reserve estimates for the properties owned by the Partnership will be
subject to a significant degree of variation due to the nature of the producing
reservoirs and the stage of depletion of the properties.


OPERATING AND CAPITAL COSTS
- ---------------------------

Huddleston has reviewed operating costs utilized by Benton and believes they
are appropriate for the subject properties.  Severance and ad valorem taxes
were deducted from gross revenues in accordance with statutory rates.  All
taxes (excluding income taxes) were estimated by Benton and have been deducted
from future revenues.

All capital costs were based on information provided by Benton.  Huddleston has
generally reviewed these costs and believes they are reasonable with respect to
the proposed operations and properties.

All capital and operating expenditures were held constant over the life of the
properties.


FACTORS NOT INCLUDED
- --------------------

Values were not assigned to nonproducing acreage or to the salvage of surface
and subsurface equipment.

General office overhead, income taxes, and allowances for depletion,
depreciation, and amortization have not been deducted from future revenues.


REPORT QUALIFICATIONS
- ---------------------

THE ESTIMATED REVENUES AND PRESENT VALUE OF THESE REVENUES ARE NOT REPRESENTED
AS MARKET VALUE.

Estimates for individual completions should be considered in context with the
overall or total estimated revenues.  Actual individual lease performances will
vary considerably from the projections particularly in comparison to the total
estimated production from all properties.

We did not inspect the properties or conduct independent well tests.
Ownership, product prices, and other factual data have been accepted as
represented by Benton.  We have generally tested these data and believe the
information is correct.

Dear Mr. Benton:

Pursuant to your request, we have audited estimates of future reserves and
associated revenues for certain properties owned by the Benton Oil & Gas
Combination Partnership 1990-1 L.P.  These projections were originally prepared
by the Benton Oil & Gas Company (Benton) engineering staff and have been
audited by Huddleston & Co., Inc. (Huddleston).  The reviewed properties are
located in West Cote Blanche Bay Field, St. Mary Parish, Louisiana, and
Umbrella Point Field, Chambers County, Texas.  Estimates of future reserves and
revenues for 100% of the discounted future revenues were audited by our firm.

A summary of the estimated reserves and revenues attributable to the subject
properties is as follows:

REPORTING REQUIREMENTS
- ----------------------

Securities and Exchange Commission (SEC) Regulation S-K, Item 102 and
Regulation S-X, Rule 4-10 and Financial Accounting Standards Board (FASB)
Statement No. 69 require oil and gas reserve information to be reported by
publicly held entities as supplemental financial data. These regulations and
standards provide for estimates of Proved reserves and associated revenues
discounted at 10% based on product prices being received on the effective date
of the report.

The Society of Petroleum Engineers (SPE) requires Proved reserves to be
economically recoverable with costs and prices in effect on the "as of" date of
the report.  In addition, the SPE has issued Standards Pertaining to the
Estimating and Auditing of Oil and Gas Reserve Information which sets standards
for the qualifications and independence of reserve estimators and auditors and
accepted methods for estimating and scheduling future reserves.

In our opinion, both the audit performed by Huddleston, and the estimates
prepared by Benton have been performed in accordance with all applicable SEC,
FASB, and SPE regulations and requirements.  It should be noted that the
reserve estimates shown herein are consistent with estimates prepared by Benton
as of January 1, 1995.

REPORT PREPARATION
- ------------------

The estimated reserves and revenues provided for this review were initially
prepared by Benton and have been reviewed in detail by our firm for the
purposes of this audit.  Where there were significant differences in the
estimated reserves and revenues, Huddleston has suggested revisions in the
Benton estimates and Benton has revised its projections accordingly.  In our
opinion, estimates for the properties, individually and in aggregate, are not
materially different from those which would have been rendered by Huddleston
had we independently projected the reserve volumes.

In performing our audit we have utilized certain geological and petrophysical

attempted to independently prepare geological interpretations or estimates of
reservoir parameters.  In some cases we have utilized information from our
files relating to previous studies of certain properties shown herein.

The projections which were reviewed for the purposes of this audit represent
100% of the total future revenues as projected by Benton.

The projections shown herein were based on performance data derived from public
sources available in January 1995; however, data of this type is subject to
delays as a result of regulatory reporting requirements and the timing of the
commercial sources providing such data.

The cash flow projections were prepared utilizing a commercially available
software package marketed by David P. Cook & Associates.  We have generally
reviewed the output of the calculation procedures utilized by the program and
believe them to be mathematically correct for the purposes of this audit.

PRODUCT PRICES
- --------------

It is our understanding that SEC regulations require future revenues to be
projected on the basis of product prices in effect on the "as of" date of the
report without further escalations or reductions.  However, certain variations
in product prices, attributable to contractual provisions, may be utilized in
the preparation of the cash flows where the prices are specified by the
contract.

The projections shown herein were based on actual product prices being received
on December 31, 1994.  These prices were held constant over the life of the
properties.

Market prices for both oil and gas continue to be subject to a significant
degree of variation in both domestic and international markets.  Future
variations in the projected prices may materially affect our projections of
economically recoverable reserves and associated revenues.

A comparison of the average product prices, weighted as a composite for all
properties, is a follows:

PROPERTY SALE
- -------------

The projections shown herein reflect the divestiture of interests owned by the
partnership in the Shallow Oil Reservoirs in West Cote Blanche Bay Field which
was effective January 1, 1995.  The partnership retained interests in the Gas
Cap Reservoirs in this property.

RESERVE ESTIMATES
- -----------------

Reserve estimates for the properties reviewed for the purpose of this audit
have been prepared with consideration of the available data and the nature of
the producing horizons.  The projections have been based on performance data
for the existing completions, analogy to other completions in the subject
reservoirs, and volumetric calculations.  Estimates prepared on the basis of
analogy and volumetric calculations will be subject to much greater variation
than those prepared for depletion drive reservoirs having established
production trends.

UMBRELLA POINT FIELD - This property operated by French Production,
Incorporated, is located in state waters offshore Chambers County, Texas, and
produces from multiple reservoirs.  Projections for this property were based
primarily on the extrapolation of production data with consideration for water
cut and pressure information where available.  We have also utilized
information from our files from previous studies prepared by our firm relating
to this property.  In general, the productive reservoirs for this property are
in the latter stages of depletion and future recoveries may be influenced by
both mechanical and reservoir factors.

WEST COTE BLANCHE BAY FIELD - Estimated reserves for the gas cap reservoirs
have been assigned on the basis of volumetric calculations for eight horizons
ranging in depth from 9,000 to 12,000 feet in three fault blocks.  The
volumetric calculations have been based on log-derived parameters and
geological interpretations prepared on the basis of subsurface information,
pressure information, and geophysical interpretations based on 3-D seismic
data.  Subsequent to our previous review, revised geological interpretations
have resulted in the transfer of reserves for the 12,600' reservoir to location
1-A (#868) from well #720 with no change in the estimated recoverable reserves.
Additional recoverable reserves have been assigned to the 38 and 38A reservoirs
based on geologic interpretations with consideration for historical performance
data.

The projected reserves for the #831 gas well, 13,900' reservoir, have been
revised relative to our July 1, 1994, evaluation on the basis of performance
data to reflect an ultimate recovery of 6,400 MMcf.  The remaining reserves for
this reservoir have been transferred to location 1- A (#868).

OTHER PROPERTIES - We have not attempted to independently prepare estimates of
future reserves for the remaining properties located in East Cameron Block 229
Field.  However, we have reviewed the projections with consideration for
historical production levels.  The Benton estimates are consistent with recent
rates of production and Benton has projected that the properties do not have
any additional economically recoverable reserves.

GENERAL CONCLUSIONS - On an overall basis, we have not encountered material
differences in our reserve estimates and those prepared by Benton.  In cases
where we have encountered significant differences in estimated recoveries,
Benton has consented to the revision of its reserve estimates to be consistent
with projections by Huddleston.  The projected reserves shown herein will be
subject to a significant level of variation due to the nature of the subject
reservoirs, the stage of depletion of the producing horizons, the reserve
estimation techniques, and the actual schedule of future remedial and
development operations.

Huddleston has relied on Benton to provide development schedules.  The
scheduling of future operations will be influenced by a variety of factors
including economic and market conditions, political considerations,
availability of funds, alternative investment opportunities, leasehold
obligations, and internal decision making.  Variations in the execution of
these development plans may have a material impact on the economic value of
both the discounted and undiscounted revenue streams.


OPERATING AND CAPITAL COSTS
- ---------------------------

Huddleston has reviewed operating costs utilized by Benton and believes they
are appropriate for the subject properties.  Costs for all properties were
consistent with historical levels.  Severance and ad valorem taxes were
deducted from gross revenues in accordance with statutory rates.  All taxes
(excluding income taxes) were estimated by Benton and have been deducted from
future revenues.

All capital costs were based on information provided by Benton.  Huddleston has
generally reviewed these costs and believes they are reasonable.  The capital
costs shown for the remedial operations for West Cote Blanche Bay Field have
been adjusted to reflect the statistical success rates of remedial operations
and variations in the depth of the historical and proposed operations.

All capital and operating expenditures were held constant over the life of the
properties.

Dear Mr. Benton:

Pursuant to your request, we have audited estimates of future reserves and
associated revenues for certain properties owned by the Benton Oil & Gas
Combination Partnership 1991-1 L.P.  These projections were originally prepared
by the Benton Oil & Gas Company (Benton) engineering staff and have been
audited by Huddleston & Co., Inc. (Huddleston).  The reviewed properties are
located in West Cote Blanche Bay Field, St. Mary Parish, Louisiana, and
Umbrella Point Field, Chambers County, Texas.  Estimates of future reserves and
revenues for 100% of the discounted future revenues were audited by our firm.

A summary of the estimated reserves and revenues attributable to the subject
properties is as follows:

REPORTING REQUIREMENTS
- ----------------------

Securities and Exchange Commission (SEC) Regulation S-K, Item 102 and
Regulation S-X, Rule 4-10 and Financial Accounting Standards Board (FASB)
Statement No. 69 require oil and gas reserve information to be reported by
publicly held entities as supplemental financial data.  These regulations and
standards provide for estimates of Proved reserves and associated revenues
discounted at 10% based on product prices being received on the effective date
of the report.

The Society of Petroleum Engineers (SPE) requires Proved reserves to be
economically recoverable with costs and prices in effect on the "as of" date of
the report.  In addition, the SPE has issued Standards Pertaining to the
Estimating and Auditing of Oil and Gas Reserve Information which sets standards
for the qualification and independence of reserve estimators and auditors and
accepted methods for estimating and scheduling future reserves.  

In our opinion, both the audit performed by Huddleston, and the estimates
prepared by Benton have been performed in accordance with all applicable SEC,
FASB, and SPE regulations and requirements.  It should be noted that the
reserve estimates shown herein are consistent with estimates prepared by Benton
as of January 1, 1995.
        
REPORT PREPARATION
- ------------------

The estimated reserves and revenues provided for this review were initially
prepared by Benton and have been reviewed in detail by our firm for the
purposes of this audit.  Where there were significant differences in the
estimated reserves and revenues, Huddleston has suggested revisions in the
Benton estimates and Benton has revised its projections accordingly.  In our
opinion, estimates for the properties, individually and in aggregate, are not
materially different from those which would have been rendered by Huddleston
had we independently projected the reserve volumes.

In performing our audit we have utilized certain geological and petrophysical
studies which were prepared by Benton and representatives of the current and
previous operators.  We have reviewed these studies and have found them to be
reasonable with respect to the subject reservoirs; however, we have not
attempted to independently prepare geological interpretations or estimates of
reservoir parameters.  In some cases we have utilized information from our
files relating to previous studies of certain properties shown herein.

The projections which were reviewed for the purposes of this audit represent
100% of the total future revenues as projected by Benton.

The projections shown herein were based on performance data derived from public
sources available in January 1995; however, data of this type is subject to
delays as a result of regulatory reporting requirements and the timing of the
commercial sources providing such data.

The cash flow projections were prepared utilizing a commercially available
software package marketed by David P. Cook & Associates.  We have generally
reviewed the output of the calculation procedures utilized by the program and
believe them to be mathematically correct for the purposes of this audit.

PRODUCT PRICES
- --------------

It is our understanding that SEC regulations require future revenues to be
projected on the basis of product prices in effect on the "as of" date of the
report without further escalations or reductions.  However, certain variations
in product prices, attributable to contractual provisions, may be utilized in
the preparation of the cash flows where the prices are specified by the
contract.

The projections shown herein have been based on actual prices being received on
December 31, 1994.  These prices were held constant over the life of the
properties.

Market prices for both oil and gas continue to be subject to a significant
degree of variation in both domestic and international markets.  Future
variations in the projected prices may materially affect our projections of
economically recoverable reserves and associated revenues.

A comparison of the average product prices, weighted as a composite for all
properties, is as follows:

<TABLE>

          Average Over Life             15.94       1.63
</TABLE>

PROJECTIONS
- -----------

The estimated reserves and revenues have been projected on a calendar year
basis with the first time period being January 1, 1995, through December 31,
1995.

PROPERTY SALE
- -------------

The projections shown herein reflect the divestiture of interests owned by the
partnership in the Shallow Oil Reservoirs in West Cote Blanche Bay Field which
was effective January 1, 1995.  The partnership retained interests in the Gas
Cap Reservoirs in this property.

RESERVES ESTIMATES
- ------------------

Reserve estimates for the properties reviewed for the purpose of this audit
have been prepared with consideration of the available data and the nature of
the producing horizons.  The projections have been based on performance data
for the existing completions, analogy to other completions in the subject
reservoirs, and volumetric calculations.  Estimates prepared on the basis of
analogy and volumetric calculations will be subject to much greater variation
than those prepared for depletion drive reservoirs having established
production trends.

UMBRELLA POINT FIELD - This property operated by French Production,
Incorporated, is located in state waters offshore Chambers County, Texas, and
produces from multiple reservoirs.  Projections for this property were based
primarily on the extrapolation of production data with consideration for water
cut and pressure information, where available.  We have also utilized
information from our files from previous studies prepared by our firm relating
to this property.  In general, the productive reservoirs for this property are
in the latter stages of depletion and future recoveries may be influenced by
both mechanical and reservoir factors.

WEST COTE BLANCHE BAY FIELD - Estimated reserves for the gas cap reservoirs
have been assigned on the basis of volumetric calculations for eight horizons
ranging in depth from 9,000 to 12,000 feet in three fault blocks.  The
volumetric calculations have been based on log-derived parameters and
geological interpretations prepared on the basis of subsurface information,
pressure information, and geophysical interpretations based on 3-D seismic
data.  Subsequent to our previous review, revised geological interpretations
have resulted in the transfer of reserves for the 12,600' reservoir to location
1-A (#868) from well #720 with no change in the estimated recoverable reserves.
Additional recoverable reserves have been assigned to the 38 and 38A reservoirs
based on geologic interpretations with consideration for historical performance
data.

The projected reserves for the #831 gas well, 13,900' reservoir, have been
revised relative to our July 1, 1994, evaluation on the basis of performance
data to reflect an ultimate recovery of 6,400 MMcf.  The remaining reserves for
this reservoir have been transferred to location 1- A (#868).


GENERAL CONCLUSIONS - On an overall basis, we have not encountered materials
differences in our reserve estimates and those prepared by Benton.  In cases
where we have encountered significant differences in estimated recoveries,
Benton has consented to the revision of its reserve estimates to be consistent
with projections by Huddleston.  The projected reserves shown herein will be
subject to a significant level of variation due to the nature of the subject
reservoirs, the stage of depletion of the producing horizons, the reserve
estimation techniques, and the actual schedule of future remedial and
development operations.

Huddleston has relied on Benton to provide development schedules.  The
scheduling of future operations will be influenced by a variety of factors
including economic and market conditions, political considerations,
availability of funds, alternative investment opportunities, leasehold
obligations, and internal decision making.  Variations in the execution of
these development plans may have a material impact on the economic value of
both the discounted and undiscounted revenue streams.


OPERATING AND CAPITAL COSTS
- ---------------------------

Huddleston has reviewed operating costs utilized by Benton and believes they
are appropriate for the subject properties.  Costs for all properties were
consistent with historical levels.  Severance and ad valorem taxes were
deducted from gross revenues in accordance with statutory rates.  all taxes
(excluding income taxes) were estimated by Benton and have been deducted from
future revenues.

All capital costs were based on information provided by Benton.  Huddleston has
generally reviewed these costs and believes they are reasonable.  The capital
costs shown for the remedial operations for West Cote Blanche Bay Field have
been adjusted to reflect the statistical success rates of remedial operations
and variations in the depth of the historical and proposed operations.

All capital and operating expenditures were held constant over the life of the
properties.

FACTORS NOT INCLUDED
- --------------------

Values were not assigned to nonproducing acreage or to the salvage of surface
and subsurface equipment.

General office overhead, income taxes, and allowances for depletion,
depreciation, and amortization have not been deducted from future revenues.

REPORT QUALIFICATIONS
- ---------------------

THE ESTIMATED REVENUES AND PRESENT VALUE OF THESE REVENUES ARE NOT REPRESENTED
AS MARKET VALUE.

Estimates for individual completions should be considered in context with the
overall or total estimated revenues.  Actual individual lease performances will
vary considerably from the projections particularly in comparison to the total
estimated production from all properties.

We did not inspect the properties or conduct independent well tests.
Ownership, product prices, and other factual data have been accepted as
represented by Benton.  We have generally tested these data and believe the
information is correct.

                                  Respectfully submitted,

                                    PART VI


                                  INSTRUCTIONS


         1.  Previously Transferred Interests.  If an Investor has transferred,
whether by sale, gift, death or otherwise, the beneficial ownership of any
Interest of which he has been named a holder of record in the accompanying
Letter of Transmittal without previously notifying Benton or complying with the
procedures set forth in the Partnership Agreement for transferring his Interest
in the Partnership, he should notify Benton of that fact and identify the
Interest transferred, the date of transfer and the name, address and tax
identification number of the assignee.  Benton will then send the Investor and
the assignee revised Letters of Transmittal and request from the Investor or
assignee such other documents as it may require in order to facilitate the
tender, if desired, of an assignee's interest in the Partnership.

         2.  Participation in Exchange.  To be entitled to receive the Common
Stock and Warrants in the Exchange, even if consent to the Proposal is
withheld, an Investor must deliver one copy of the Letter of Transmittal,
completed, dated and signed in the Signature Box in Part IV or the Signature
Box in Part V for Non-consenting California residents.  Delivery is at the risk
of the Investor.  A tender will be effective only when the Letter is actually
received by the Exchange Agent.  The Letter must be received by the Exchange
Agent on or before 5:00 p.m. Eastern Time, on ________________ unless the
Exchange Offer is extended, in which event the Letter must be received by the
latest time and date on which the Exchange Offer, as so extended, will expire.

         3.  Signatures.  The Letter must be signed by the Investor whose name
appears in Part I of the Letter.  If the Interest is held in the names of two
or more persons, all such persons must sign the Letter.  With respect to
Interests held by entities such as trusts, joint ventures, limited partnerships
or general partnerships, Benton may require that the Letter of Transmittal be
accompanied by evidence acceptable to Benton that the entity has met all
requirements of its governing instruments, such as applicable partnership or
joint venture agreements, and that the person signing the Letter is authorized
to sign for the Investor under the laws of the jurisdiction in which the entity
was organized.

         TO PARTICIPATE IN THE EXCHANGE OFFER, AN INVESTOR MUST SIGN IN THE
SIGNATURE BLOCK IN PART IV (OR PART V FOR CALIFORNIA INVESTORS), EVEN IF HE
OBJECTS TO THE EXCHANGE OFFER AND ELECTS TO WITHHOLD HIS CONSENT TO THE
PROPOSAL.  INVESTORS WILL NOT RECEIVE UNITS IN THE EXCHANGE UNTIL A SIGNED
LETTER OF TRANSMITTAL IS RETURNED.

         4.  Conditional Tenders.  No alternative, conditional or contingent
             tenders will be accepted.

         5.  Withdrawal of Tenders.  Tenders of Interests and consents to the
Proposal are revocable at any time prior to the Expiration Date by delivering a
notice of withdrawal to Benton.

         6.  Validity of Tenders.  All questions on the validity, form,
eligibility (including time of receipt) and acceptance of Interests will be
determined by Benton, and its determination will be final and binding.
Interpretation by Benton of the terms and conditions of the Exchange Offer
(including the instructions to the Letter of Transmittal) will also be final
and binding.  Benton reserves the right to waive any irregularities or
conditions on the manner of tender, and the interpretation by Benton of the
terms and conditions of the Exchange Offer (including the instructions in the
Letter of Transmittal) shall be final and binding.  Any irregularities in
connection with tenders must be cured within such time as Benton shall
determine unless waived by it.
<PAGE>   244
         Tenders will be deemed not to have been made until any irregularities
have been cured or waived.  Any Letter of Transmittal which is not properly
completed and executed, and as to which irregularities are not cured or waived,
will be returned by Benton to the Investor as soon as practicable.  Benton is
under no duty to give notification of defects in tenders and will not incur any
liability for failure to give notification.

         Benton will not accept tenders of less than all of an Investor's
Interest in the Partnership.

         7.  Consents to Proposal.  A tender of an Interest constitutes a
consent to the Proposal.  Only persons who are holders of record of Partnership
Interests on the date of the Prospectus may vote on the Proposal.

         8.  Dissenters' Rights for California Residents.  Investors residing
in California have limited dissenters' rights in accordance with the
requirements for rollup transactions.  By signing Part V and thereby
withholding consent to the Proposal, Investors in that State will be deemed to
exercise their dissenters' rights and will receive the number of Shares of
Common Stock equal to the Exchange Value of their Interests divided by the
average closing prices of the Units on NASDAQ-NMS during the twenty trading
days immediately after the Closing Date.  Each California Investor withholding
consent to the Proposal will also be deemed to have tendered his Interest for
that number of Units and therefore will not be required to separately submit an
executed Transfer Application.  If the average price of the Units during the
specified period after the Closing Date is lower than the Exchange Price,
dissenting California Investors will receive more for their Interests than they
would otherwise receive in the Exchange Offer.  Any increase in the market
price of the Common Stock during that period relative to the Exchange Price,
however, would reduce the number of shares that dissenting California Investors
will receive in the Exchange Offer.

         Although the rollup requirements for California residents entitle them
to an appraisal in rollup transactions involving their investments, Investors
residing in California who exercise these dissenters' rights will not be
entitled to a separate appraisal for their Interests because the Exchange Value
of the Common Stock determined by Benton exceeds the liquidation value assigned
to the Partnership's net assets in an independent appraisal already performed
in accordance with the Partnership Agreement.

            BENTON OIL AND GAS COMBINATION PARTNERSHIP 1990 - 1 L.P.


         Capitalized terms used but not defined herein have the meanings given
to them in the Prospectus of Benton Oil and Gas Company, as supplemented or
amended (the "Prospectus").  General instructions are included in Part VI.

         This Letter of Transmittal must be received by the Exchange Agent on
or before 5:00 p.m. Eastern Time, on ______________, 1995 unless the Exchange
Offer is extended.  To accept the Exchange Offer or withhold consent to the
related Proposal, please complete this Letter in accordance with the
Instructions in Items IV and VI, and send or deliver the completed Letter of
Transmittal to the Exchange Agent.  Neither accepting the Exchange Offer nor
withholding consent to the Proposal will prevent an Investor from challenging
the fairness of the Exchange Offer.

         Adoption of the Proposal requires consent by Investors holding 75% of
the units in the Partnership.  Assuming consummation of the Exchange Offer, all
of the partners of the Partnership, whether or not they tender their Interests,
will receive the same number of shares of Common Stock and Warrants they would
have received had they tendered their Interests, except that California
investors exercising their limited dissenters' rights may receive a higher or
lower number of shares or warrants.  See Part V below and "The Exchange Offer
and Proposal" in the Prospectus.

                                    PART VI


                                  INSTRUCTIONS


         1.  Previously Transferred Interests.  If an Investor has transferred,
whether by sale, gift, death or otherwise, the beneficial ownership of any
Interest of which he has been named a holder of record in the accompanying
Letter of Transmittal without previously notifying Benton or complying with the
procedures set forth in the Partnership Agreement for transferring his Interest
in the Partnership, he should notify Benton of that fact and identify the
Interest transferred, the date of transfer and the name, address and tax
identification number of the assignee.  Benton will then send the Investor and
the assignee revised Letters of Transmittal and request from the Investor or
assignee such other documents as it may require in order to facilitate the
tender, if desired, of an assignee's interest in the Partnership.

         2.  Participation in Exchange.  To be entitled to receive the Common
Stock and Warrants in the Exchange, even if consent to the Proposal is
withheld, an Investor must deliver one copy of the Letter of Transmittal,
completed, dated and signed in the Signature Box in Part IV or the Signature
Box in Part V for Non-consenting California residents.  Delivery is at the risk
of the Investor.  A tender will be effective only when the Letter is actually
received by the Exchange Agent.  The Letter must be received by the Exchange
Agent on or before 5:00 p.m. Eastern Time, on ________________ unless the
Exchange Offer is extended, in which event the Letter must be received by the
latest time and date on which the Exchange Offer, as so extended, will expire.

         3.  Signatures.  The Letter must be signed by the Investor whose name
appears in Part I of the Letter.  If the Interest is held in the names of two
or more persons, all such persons must sign the Letter.  With respect to
Interests held by entities such as trusts, joint ventures, limited partnerships
or general partnerships, Benton may require that the Letter of Transmittal be
accompanied by evidence acceptable to Benton that the entity has met all
requirements of its governing instruments, such as applicable partnership or
joint venture agreements, and that the person signing the Letter is authorized
to sign for the Investor under the laws of the jurisdiction in which the entity
was organized.

         TO PARTICIPATE IN THE EXCHANGE OFFER, AN INVESTOR MUST SIGN IN THE
SIGNATURE BLOCK IN PART IV (OR PART V FOR CALIFORNIA INVESTORS), EVEN IF HE
OBJECTS TO THE EXCHANGE OFFER AND ELECTS TO WITHHOLD HIS CONSENT TO THE
PROPOSAL.  INVESTORS WILL NOT RECEIVE UNITS IN THE EXCHANGE UNTIL A SIGNED
LETTER OF TRANSMITTAL IS RETURNED.

         4.  Conditional Tenders.  No alternative, conditional or contingent
tenders will be accepted.

         5.  Withdrawal of Tenders.  Tenders of Interests and consents to the
Proposal are revocable at any time prior to the Expiration Date by delivering a
notice of withdrawal to Benton.

         6.  Validity of Tenders.  All questions on the validity, form,
eligibility (including time of receipt) and acceptance of Interests will be
determined by Benton, and its determination will be final and binding.
Interpretation by Benton of the terms and conditions of the Exchange Offer
(including the instructions to the Letter of Transmittal) will also be final
and binding.  Benton reserves the right to waive any irregularities or
conditions on the manner of tender, and the interpretation by Benton of the
terms and conditions of the Exchange Offer (including the instructions in the
Letter of Transmittal) shall be final and binding.  Any irregularities in
connection with tenders must be cured within such time as Benton shall
determine unless waived by it.
<PAGE>   251
         Tenders will be deemed not to have been made until any irregularities
have been cured or waived.  Any Letter of Transmittal which is not properly
completed and executed, and as to which irregularities are not cured or waived,
will be returned by Benton to the Investor as soon as practicable.  Benton is
under no duty to give notification of defects in tenders and will not incur any
liability for failure to give notification.

         Benton will not accept tenders of less than all of an Investor's 
Interest in the Partnership.

         7.  Consents to Proposal.  A tender of an Interest constitutes a
consent to the Proposal.  Only persons who are holders of record of Partnership
Interests on the date of the Prospectus may vote on the Proposal.

         8.  Dissenters' Rights for California Residents.  Investors residing
in California have limited dissenters' rights in accordance with the
requirements for rollup transactions.  By signing Part V and thereby
withholding consent to the Proposal, Investors in that State will be deemed to
exercise their dissenters' rights and will receive the number of Shares of
Common Stock equal to the Exchange Value of their Interests divided by the
average closing prices of the Units on NASDAQ-NMS during the twenty trading
days immediately after the Closing Date.  Each California Investor withholding
consent to the Proposal will also be deemed to have tendered his Interest for
that number of Units and therefore will not be required to separately submit an
executed Transfer Application.  If the average price of the Units during the
specified period after the Closing Date is lower than the Exchange Price,
dissenting California Investors will receive more for their Interests than they
would otherwise receive in the Exchange Offer.  Any increase in the market
price of the Common Stock during that period relative to the Exchange Price,
however, would reduce the number of shares that dissenting California Investors
will receive in the Exchange Offer.

         Although the rollup requirements for California residents entitle them
to an appraisal in rollup transactions involving their investments, Investors
residing in California who exercise these dissenters' rights will not be
entitled to a separate appraisal for their Interests because the Exchange Value
of the Common Stock determined by Benton exceeds the liquidation value assigned
to the Partnership's net assets in an independent appraisal already performed
in accordance with the Partnership Agreement.

                                  INVESTORS IN
            BENTON OIL AND GAS COMBINATION PARTNERSHIP 1991 - 1 L.P.


         Capitalized terms used but not defined herein have the meanings given
to them in the Prospectus of Benton Oil and Gas Company, as supplemented or
amended (the "Prospectus").  General instructions are included in Part VI.

         This Letter of Transmittal must be received by the Exchange Agent on
or before 5:00 p.m. Eastern Time, on ______________, 1995 unless the Exchange
Offer is extended.  To accept the Exchange Offer or withhold consent to the
related Proposal, please complete this Letter in accordance with the
Instructions in Items IV and VI, and send or deliver the completed Letter of
Transmittal to the Exchange Agent.  Neither accepting the Exchange Offer nor
withholding consent to the Proposal will prevent an Investor from challenging
the fairness of the Exchange Offer.

         Adoption of the Proposal requires consent by Investors holding 75% of
the units in the Partnership.  Assuming consummation of the Exchange Offer, all
of the partners of the Partnership, whether or not they tender their Interests,
will receive the same number of shares of Common Stock and Warrants they would
have received had they tendered their Interests, except that California
investors exercising their limited dissenters' rights may receive a higher or
lower number of shares or warrants.  See Part V below and "The Exchange Offer
and Proposal" in the Prospectus.

                                    PART VI


                                  INSTRUCTIONS


         1.  Previously Transferred Interests.  If an Investor has transferred,
whether by sale, gift, death or otherwise, the beneficial ownership of any
Interest of which he has been named a holder of record in the accompanying
Letter of Transmittal without previously notifying Benton or complying with the
procedures set forth in the Partnership Agreement for transferring his Interest
in the Partnership, he should notify Benton of that fact and identify the
Interest transferred, the date of transfer and the name, address and tax
identification number of the assignee.  Benton will then send the Investor and
the assignee revised Letters of Transmittal and request from the Investor or
assignee such other documents as it may require in order to facilitate the
tender, if desired, of an assignee's interest in the Partnership.

         2.  Participation in Exchange.  To be entitled to receive the Common
Stock and Warrants in the Exchange, even if consent to the Proposal is
withheld, an Investor must deliver one copy of the Letter of Transmittal,
completed, dated and signed in the Signature Box in Part IV or the Signature
Box in Part V for Non-consenting California residents.  Delivery is at the risk
of the Investor.  A tender will be effective only when the Letter is actually
received by the Exchange Agent.  The Letter must be received by the Exchange
Agent on or before 5:00 p.m. Eastern Time, on ________________ unless the
Exchange Offer is extended, in which event the Letter must be received by the
latest time and date on which the Exchange Offer, as so extended, will expire.

         3.  Signatures.  The Letter must be signed by the Investor whose name
appears in Part I of the Letter.  If the Interest is held in the names of two
or more persons, all such persons must sign the Letter.  With respect to
Interests held by entities such as trusts, joint ventures, limited partnerships
or general partnerships, Benton may require that the Letter of Transmittal be
accompanied by evidence acceptable to Benton that the entity has met all
requirements of its governing instruments, such as applicable partnership or
joint venture agreements, and that the person signing the Letter is authorized
to sign for the Investor under the laws of the jurisdiction in which the entity
was organized.

         TO PARTICIPATE IN THE EXCHANGE OFFER, AN INVESTOR MUST SIGN IN THE
SIGNATURE BLOCK IN PART IV (OR PART V FOR CALIFORNIA INVESTORS), EVEN IF HE
OBJECTS TO THE EXCHANGE OFFER AND ELECTS TO WITHHOLD HIS CONSENT TO THE
PROPOSAL.  INVESTORS WILL NOT RECEIVE UNITS IN THE EXCHANGE UNTIL A SIGNED
LETTER OF TRANSMITTAL IS RETURNED.

         4.  Conditional Tenders.  No alternative, conditional or contingent
tenders will be accepted.

         5.  Withdrawal of Tenders.  Tenders of Interests and consents to the
Proposal are revocable at any time prior to the Expiration Date by delivering a
notice of withdrawal to Benton.

         6.  Validity of Tenders.  All questions on the validity, form,
eligibility (including time of receipt) and acceptance of Interests will be
determined by Benton, and its determination will be final and binding.
Interpretation by Benton of the terms and conditions of the Exchange Offer
(including the instructions to the Letter of Transmittal) will also be final
and binding.  Benton reserves the right to waive any irregularities or
conditions on the manner of tender, and the interpretation by Benton of the
terms and conditions of the Exchange Offer (including the instructions in the
Letter of Transmittal) shall be final and binding.  Any irregularities in
connection with tenders must be cured within such time as Benton shall
determine unless waived by it.
<PAGE>   258
         Tenders will be deemed not to have been made until any irregularities
have been cured or waived.  Any Letter of Transmittal which is not properly
completed and executed, and as to which irregularities are not cured or waived,
will be returned by Benton to the Investor as soon as practicable.  Benton is
under no duty to give notification of defects in tenders and will not incur any
liability for failure to give notification.

         Benton will not accept tenders of less than all of an Investor's
Interest in the Partnership.

         7.  Consents to Proposal.  A tender of an Interest constitutes a
consent to the Proposal.  Only persons who are holders of record of Partnership
Interests on the date of the Prospectus may vote on the Proposal.

         8.  Dissenters' Rights for California Residents.  Investors residing
in California have limited dissenters' rights in accordance with the
requirements for rollup transactions.  By signing Part V and thereby
withholding consent to the Proposal, Investors in that State will be deemed to
exercise their dissenters' rights and will receive the number of Shares of
Common Stock equal to the Exchange Value of their Interests divided by the
average closing prices of the Units on NASDAQ-NMS during the twenty trading
days immediately after the Closing Date.  Each California Investor withholding
consent to the Proposal will also be deemed to have tendered his Interest for
that number of Units and therefore will not be required to separately submit an
executed Transfer Application.  If the average price of the Units during the
specified period after the Closing Date is lower than the Exchange Price,
dissenting California Investors will receive more for their Interests than they
would otherwise receive in the Exchange Offer.  Any increase in the market
price of the Common Stock during that period relative to the Exchange Price,
however, would reduce the number of shares that dissenting California Investors
will receive in the Exchange Offer.

         Although the rollup requirements for California residents entitle them
to an appraisal in rollup transactions involving their investments, Investors
residing in California who exercise these dissenters' rights will not be
entitled to a separate appraisal for their Interests because the Exchange Value
of the Common Stock determined by Benton exceeds the liquidation value assigned
to the Partnership's net assets in an independent appraisal already performed
in accordance with the Partnership Agreement.

                                     PART II

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Under provisions of the Certificate of Incorporation and Bylaws of the
Company, each person who is or was a director or officer of the Company shall be
indemnified by the Company as a matter of right to the full extent permitted or
authorized by law. The effects of the Certificate of Incorporation, Bylaws and
General Corporation Law of Delaware may be summarized as follows:

                  (a) Under Delaware law, to the extent that such a person is
         successful on the merits in defense of a suit or proceeding brought
         against him by reason of the fact that he is a director or officer of
         the Company, he shall be indemnified against expenses (including
         attorneys' fees) reasonably incurred in connection with such action.

                  (b) If unsuccessful in defense of a third-party civil suit or
         a criminal suit, or if such a suit is settled, such a person shall be
         indemnified under such law against both (1) expenses (including
         attorneys' fees) and (2) judgments, fines and amounts paid in
         settlement if he acted in good faith and in a manner he reasonably
         believed to be in, or not opposed to, the best interests of the
         Company, and with respect to any criminal action, had no reasonable
         cause to believe his conduct was unlawful.

                  (c) If unsuccessful in defense of a suit brought by or in the
         right of the Company, or if such suit is settled, such a person shall
         be indemnified under such law only against expenses (including
         attorneys' fees) incurred in the defense or settlement of such suit if
         he acted in good faith and in a manner he reasonably believed to be in,
         or not opposed to, the best interests of the Company except that if
         such a person is adjudged to be liable in a suit in the performance of
         his duty to the Company, he cannot be made whole even for expenses
         unless the court determines that he is fairly and reasonably entitled
         to indemnity for such expenses.

                  (d) The Company may not indemnify a person in respect of a
         proceeding described in (b) or (c) above unless it is determined that
         indemnification is permissible because the person has met the
         prescribed standard of conduct by any one of the following: (i) the
         Board of Directors, by a majority vote of a quorum consisting of
         directors not at the time parties to the proceeding, (ii) if a quorum
         of directors not parties to the proceeding cannot be obtained, or, if
         obtainable but the quorum so directs, by independent legal counsel
         selected by the Board of Directors or the committee thereof; or (iii)
         by the stockholders.

ITEM 22.  UNDERTAKINGS.

         a.       The undersigned registrant hereby undertakes:

                  (1)      To file, during any period in which offers or sales
                           are being made, a post-effective amendment to this
                           registration statement:

                           (i)      To include any prospectus required by
                                    Section 10(a)(3) of the Securities Act of
                                    1993;

                           (ii)     To reflect in the prospectus any facts or
                                    events arising after the effective date of
                                    the registration statement (or the most
                                    recent post-effective amendment thereof)
                                    which, individually or in the aggregate,
                                    represents a fundamental change in the
                                    information set forth in the registration
                                    statement;

                           (iii)    To include any material information with

                  (2)      That, for the purpose of determining any liability
                           under the Securities Act of 1933, each such
                           post-effective amendment shall be deemed to be a new
                           registration

                           statement relating to the securities offered therein
                           and the offering of such securities at that time
                           shall be deemed to be the initial bona fide offering
                           thereof.

                  (3)      To remove from registration by means of a
                           post-effective amendment any of the securities being
                           registered which remain unsold at the termination of
                           the offering.

                  (4)      If the registrant is a foreign private
                           issuer, to file a post-effective amendment
                           to the registration statement to include any
                           financial statements required by Section 210.3-19 of
                           this chapter at the start of any delayed offering of
                           throughout a continuous offering. Financial
                           statements and information otherwise required by
                           Section 10(a)(3) of the Act need not be furnished,
                           provided that the registrant includes in the
                           prospectus, by means of a post-effective amendment,
                           financial statements required pursuant to this
                           paragraph (a)(4) and other information necessary to
                           ensure that all other information in the prospectus
                           is at least as current as the date of those
                           financial statements.

         b.       The undersigned registrant hereby undertakes to deliver or
                  cause to be delivered with the prospectus, to each person to
                  whom the prospectus is sent or given, the latest annual report
                  to security holders that is incorporated by reference in the
                  prospectus and furnished pursuant to and meeting the
                  requirements of Rule 14a-3 or Rule 14c-3 under the Securities
                  Exchange Act of 1934; and, where interim financial information
                  required to be presented by Article 3 of Regulation S-X are
                  not set forth in the prospectus, to deliver, or cause to be
                  delivered to each person to whom the prospectus is sent or
                  given, the latest quarterly report that is specifically
                  incorporated by reference in the prospectus to provide such
                  interim financial information.

         c.       (1)      The undersigned registrant hereby undertakes as
                           follows: that prior to any public reoffering of the
                           securities registered hereunder through use of a
                           prospectus which is a part of this registration
                           statement, by any person or party who is deemed to be
                           an underwriter within the meaning of Rule 145(c), the
                           issuer undertakes that such reoffering prospectus

of a well when total depth has been reached, appropriate tests have been made
and a decision must be made to run and set production casing or production
liner, as the case may be, and a decision to commence attempting to complete
the well is made or the well is plugged and abandoned. 

        COMPLETION COSTS. "Completion Costs" means, as to any well, all those
costs incurred after Casing Point.  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.

        COST.  When used in connection with selling undeveloped leases and
other interests to the Partnership or providing for the drilling of a
Partnership well by Benton, EPC and their Affiliates, "Cost" shall mean the sum
of (1) the amounts paid by Benton, EPC or their Affiliates to unaffiliated
third parties for the property, including bonuses; (2) title insurance or title
examination costs, brokers' commissions, filing fees, recording costs, transfer
taxes, if any, and like charges in connection with the acquisition of the
property; (3) delay rentals and ad valorem taxes paid with respect to the
property to the date of its transfer to the Partnership; (4) interest on funds
used to acquire or maintain the property; (5) equipment, drilling, seismic and

services, including a share of compensation of employees or officers, allocated
to the property in accordance with generally accepted and customary industry
practices, and screening costs paid to third parties for geological,
geophysical and seismic evaluations of Benton's, EPC's or their Affiliates'
lease inventory, to the extent such evaluations condemn the acreage prior to
selection for the Partnership.  Delay rentals, ad valorem taxes, interest on
funds used to acquire or maintain properties and direct expenses will not be
included in "Cost" when such expenses were incurred by Benton, EPC or their
Affiliates in connection with the past drilling of wells which are not
producers of sufficient quantities of oil or gas to make commercially
reasonable their continued operation, or when such expenses, as enumerated in
subsections (3) and (4) hereof, were incurred more than 36 months prior to the
purchase of the property interest by the Partnership.  When used with respect
to services, "Cost" means the reasonable, necessary and actual expenses
incurred by Benton, EPC or their Affiliates on behalf of the Partnership in
providing such services, determined in accordance with generally accepted and
customary industry practices.  Except as otherwise indicated or as the context
requires, "cost" means the price paid by Benton, EPC or their Affiliates in a
fair or arm's length transaction.

                      ARTICLE IV. CAPITAL OF THE PARTNERS
            
        A.   CAPITAL CONTRIBUTIONS 

                                      5
<PAGE>   9
                (1)      Each Participant has made a capital contribution to
         the Partnership in cash equal to the amount set forth in the
         Subscription Agreement submitted to EPC by the Participants and
         accepted by EPC.  A Participant's interest in the Partnership,
         including his interest in undistributed profits, will be subject to
         the debts of the Partnership. 

                (2)      Benton and EPC will make a capital contribution to the
         Partnership as required to pay their share of costs as provided in
         Article V hereof, and in return for such payments, Benton, EPC and
         other General Partners shall be entitled to share in all items of
         income, gain, loss, deduction or credit allocated to the respective
         Partners as provided in Article VI. 

                (3)      Benton and EPC will make a capital contribution as a 1%
         General Partner if no other Participants subscribe for general
         partnership units.  Otherwise, Benton and EPC will make no capital
         contribution for their interest. 

                (4)      Each investor is subject to assessments in the amount
         of up to 25% of the amount of their original capital contribution.  

        B. DETERMINATION OF CAPITAL ACCOUNTS 

        A single capital account shall be maintained for each Partner (or
transferee of a Partner, which transferee shall have the capital account of his
transferor, as of the effective date of the transfer).  The capital account for
each Partner will be determined based on the Regulations regarding maintenance
of capital accounts promulgated under {704(b) of the Internal Revenue Code. 
Generally, these Regulations provide that capital accounts of Partners shall be
increased by (1) the amount of money contributed by a partner to the
partnership, (2) the fair market value of property contributed by a partner to
the partnership, (3) allocation to a partner of partnership income and gain (or
items thereof), and (4) interest earned on Subscriptions after formation of the
Partnership.  Capital accounts will be decreased by (1) the amount of money
distributed to a Partner by the Partnership, (2) the fair market value of
property distributed to a Partner by the Partnership, (3) allocations of
Partnership loss and deduction (or items thereof), and (4) organizational and
syndication costs which are not amortized. 

        In the event of a distribution in kind of any property, the capital
accounts of the Partners shall first be adjusted to reflect the manner in which
the unrealized income, gain, or loss inherent in the property (which has not
been previously reflected in capital accounts) would be allocated among the
Partners if there were a taxable disposition of the property at its fair market
value. 

        C.      SIMULATED DEPLETION ACCOUNT

        Solely for purposes of maintaining capital accounts, depletion with
respect to oil and gas properties shall be computed at the Partnership level.
The Partnership shall compute a simulated depletion allowance on each oil or
gas property using the percentage depletion method.  The Partnership's
simulated depletion allowance shall reduce the Partners' capital accounts in
the 

                                      6
<PAGE>   10
same proportion as such Partners (or their predecessors in interest) were
allocated adjusted basis with respect to such property.  The aggregate capital
account adjustments for simulated depletion allowances with respect to an oil
or gas property shall not exceed the Partnership's adjusted tax basis in such
property.  Upon the taxable disposition of an oil or gas property by the
Partnership, the Partnership's simulated gain or loss shall be determined by
subtracting its simulated adjusted basis in such property from the amount
realized from such disposition.  (The Partnership's simulated adjusted basis in
an oil and gas property is determined in the same manner as adjusted tax basis
except that simulated depletion allowances are taken into account instead of
actual depletion allowances.)  Any resultant simulated gain shall be allocated
to the Partners in the same manner as that portion of the amount realized from
such disposition which exceeds the Partnership's simulated adjusted basis in
such property is allocated to such Partners and shall increase such Partners'
capital accounts accordingly.  Any resultant simulated loss shall be allocated
to the Partners in proportion to the Partners' allocable shares of the total
amount realized from the disposition of such property that represents recovery
of the Partnership's simulated adjusted basis in such property, and shall
reduce such Partners' capital accounts accordingly.

        D.       INTEREST ON CAPITAL 

        No interest shall be paid on the capital account of or capital
contributed by any Partner either before or after the time repayment should be
made.

                     ARTICLE V. COSTS CHARGED TO PARTNERS

        The accounts of the Partners shall be charged as follows for items
expended by the Partnership, provided that costs paid out of assessments shall
only be charged to Partners who paid such assessments:

        A.      PARTNERSHIP COSTS 

        All Partnership Well Costs, including completion costs, costs of
Recompletion Wells, costs of acquiring Proven Producing Properties, geological,
geophysical and seismic costs and Organization and Offering Expenses shall be
allocated one hundred percent (100%) to the Participants. 

        B.      OPERATING COSTS 

        The expenses of operating Partnership wells are to be shared in the
same ratio that revenues are shared in such wells, pursuant to paragraph A of
Article VI.  In addition, operating costs shall include the costs of
recompleting Partnership Wells.

                                      7
<PAGE>   11
        C.      OTHER COSTS  

        All costs which are not otherwise specifically
provided for in Article V(A) above, including, but not limited to General and
Administrative and Direct Expenses, shall be allocated one hundred percent
(100%) to the Participants. 

        Costs charged to Participants and the Co-Managing General Partners 
will be allocated among the Participants as provided below in paragraph C of 
Article VI. 

        D.      LOSS ON SALE OF PARTNERSHIP ASSETS 

        If the Partnership sells any oil and gas property at a price which is
less than its undepleted cost, the Partnership shall allocate the loss on such
sale to the Partners in the ratio of their remaining undepleted bases in such
property at the time of sale. 

        If the Partnership sells any asset, other than an oil and gas property,
at a price which is less than its undepreciated cost, the Partnership shall
allocate the loss on such sale to the Partners who bore the cost of such asset. 

         ARTICLE VI. ALLOCATION OF REVENUES AND DISTRIBUTIONS OF CASH

        A. REVENUES      

        All Partnership Revenues from Proven Producing Properties shall be
allocated one hundred percent (100%) to the Participants.  All Partnership
Revenues from Recompleted Wells shall be allocated seventy-five percent (75%)
to the Participants and twenty-five percent (25%) to the Co-Managing General
Partners.  All Partnership revenues from Partnership Wells shall be allocated
sixty-five percent (65%) to the Participants and thirty-five percent (35%) to
the Co-Managing General Partners.  For Partnership purposes, "Revenues" shall
mean funds received by the Partnership from all sources, except capital
contributions, borrowings, assessments and interest on subscriptions, whether
occurring during the term of the Partnership or occurring as part of any plan
of dissolution and liquidation of the Partnership.  Provided, however, that the
portion of the revenues generated by the taxable disposition of a Partnership
oil and gas property that represents recovery of its simulated adjusted tax
basis therein will be allocated to the Partners in the same proportion such
Partners (or their predecessors in interest) were allocated the basis of such
property pursuant to paragraph C of Article IV.  Provided further, that the
portion of the revenues generated by the taxable disposition of a Partnership
asset, other than an oil and gas property, equal to the Partnership's adjusted
tax basis in such property shall be allocated to the Partners in the same
proportion that the Partners bore the cost of such asset.

                                      8
<PAGE>   12
        B.      CASH DISTRIBUTIONS

        (1)      The Partnership expects to distribute quarterly, or on a more
current basis if so determined by the Co-Managing General Partners, amounts to
the Participants equal to approximately the difference between revenues
allocated to the respective Partners as provided in this Article, and costs
charged to the Partners as provided in Article V.  This provision shall not,
however, serve as a limitation on Benton's right to retain, pledge or use so
much of the revenues or other assets of the Partnership, including amounts
required to eliminate any capital deficit of the Partners, to conduct
additional operations of the Partnership, to establish reserves for anticipated
expenditures, or to repay any amounts borrowed by the Partnership to finance
the conduct of such operations.

        (2)      Upon the sale of any Partnership property at a gain, a
Partner's share of any gain may be applied to reduction of any deficits in
capital accounts of Partners caused by distribution in excess of their share of
Partnership profits and losses.





        C.      ALLOCATIONS AMONG PARTICIPANTS AND CO-MANAGING GENERAL PARTNERS

         All allocations of income, gain, loss and deduction to the
Participants as a class shall be allocated among the Participants based on the
ratio of their respective paid capital contributions, including assessments.
Expenses and other costs paid from assessments shall be allocated only to those
Partners who paid the assessment.  All allocations of income, gain, loss,
deduction and all capital contributions and assessments to the Co-Managing
General Partners will be divided 80% to Benton and 20% to EPC.


              ARTICLE VII. ELECTIONS AND ALLOCATION OF DEDUCTIONS

              For purposes of federal income taxes, and appropriate state or 
local income taxes, the following allocations shall be made:


        A.    To the extent permitted by law, all income, gain, losses and      
deductions shall be allocated to the party who has been charged with the
expenditures or credited with the revenues giving rise to such deductions or
income; and to the extent permitted by law, such party shall be entitled to
such deductions and income in computing taxable income or tax liabilities to
the exclusion of any other party.

        B.      The basis of Partnership properties for purposes of Code
Section 613A(c)(7)(D) shall be allocated in the same ratio as Partnership Costs
are allocated.

        C.      Notwithstanding the foregoing, however, production required to
be allocated for the purpose of computing the depletion deduction (including
percentage depletion in excess of the depletable basis of the property) shall
be allocated in the ratio in which the related revenues are shared.

                                      9
<PAGE>   13
        D.      All tax credits and tax credit recapture shall be allocated in
the ratio in which revenues are shared at the time the expenditure giving rise
to such tax credit arises. 

        E.      The Partnership shall make an election to deduct intangible
drilling and development costs on its federal income tax return in accordance
with the option granted by the Internal Revenue Code of 1986.  No election
shall be made by the Partnership to be excluded from the application of the
provisions of Subchapter K of the Internal Revenue Code of 1986. 

        F.      In the event of the transfer of an interest in the Partnership,
or in the event of the distribution of property to any party hereto, the
Partnership may (but is not required to) file an election in accordance with
the applicable Treasury Regulations to cause the basis of the Partnership's
assets to be adjusted for federal income tax purposes as provided by {{734 and
743 of the Internal Revenue Code of 1986. 

        G.      Notwithstanding any other provision of this Article VII, if the
capital accounts of all Participants are not equal and if any allocation of
loss or deduction to a Partner would reduce such Participant's capital account
balance below zero or would increase the negative balance in such Participant's
capital account at a time when another Participant has a positive capital
account balance, as determined at the close of the period in respect of which
the loss or deduction, as the case may be, is to be allocated, such excess
shall instead be allocated pro rata to Participants having positive capital
account balances until such capital account balances are reduced to zero;
provided, however, that in no event shall there be a reallocation of any item
of income, gain, loss or deduction allocated among the Partners pursuant to
this Agreement for prior years.


        Notwithstanding any other provision of this Article VII, if any
allocation of loss or deduction would cause the capital account balances of any
Participant to be negative (or would increase the negative balance of a
Participant's capital account) at a time when no other Participant has a
positive capital account balance, such loss or deduction shall instead be
allocated to the Co-Managing General Partners. 

        For purposes of determining a Participant's capital account balance
under this Paragraph G, distributions made prior to or contemporaneous with any
allocation to a Participant shall be reflected in such Participant's capital
account prior to making such allocation to such Participant.  For purposes of
this paragraph G, a Partner's capital account shall be reduced for: 

                (1)      Adjustments that, as of the end of each Partnership
         year, reasonably are expected to be made to such Partner's capital
         account under paragraph (b)(2)(iv)(k) of Treas. Reg. {1.704-1 for
         depletion allowances with respect to oil and gas properties of the
         Partnership, and
                 
                (2)      Allocations of loss and deduction which, as of the end
         of such year, are reasonably expected to be allocated to such Partner
         pursuant to Code Section 704(e)(2), Code Section 706(d) and Treas.
         Reg. {1.751-1(b)(2)(ii), and

                                      10
<PAGE>   14
                (3)     Distributions that, as of the end of such year,
         reasonably are expected to be made to such Partner to the extent they
         exceed offsetting increases to such Partner's capital account that
         reasonably are expected to occur during (or prior to) the Partnership
         taxable years in which such distributions reasonably are expected to
         be made. 

        For purposes of determining the amount of expected distributions and
expected capital account increases described in (3) above:  (i) the rule set
forth in Treas. Reg. {1.704-1(b)(2)(iii)(c) concerning the presumed value of
Partnership property shall apply, and (ii) gross income or items of income or
gain allocated to a Partner pursuant to paragraph H hereof shall be taken into
account. For purposes of this paragraph G and paragraph H, a Partner's
capital account shall be increased to the extent that such Partner is obligated
to fund deficits in such Partner's capital account upon liquidation of the
Partnership (or is treated as obligated to so restore such deficits pursuant to
Treas. Reg. {1.704-1(b)(2)(ii)(c)). 

        H.      In the event any Partners unexpectedly receive any adjustments,
allocations, or distributions described in Treas. Reg.{1.704-1(b)(2)(ii)(d)(4),
1.704(b)(2)(ii)(d)(5), or 1.704-1(b)(2)(ii)(d)(6) so as to cause a deficit, or
increase a deficit, in the Partner's capital account, items of Partnership
income and gains shall be specially allocated to such Partners in an amount and
manner sufficient to eliminate the deficit balances in their capital accounts
created by such adjustments, allocations, or distributions as quickly as
possible.  Any special allocations of income, gain, loss or deduction pursuant
to paragraph G and this paragraph H shall be taken into account in computing
subsequent allocations of income, gain, loss and deduction pursuant to this
Article VII, so that the net amount of any items so allocated and the income,
gain, loss and deduction and all other items allocated to each Partner pursuant
to this Article VII shall, to the extent possible, be equal to the net amount
that would have been allocated to each such Partner pursuant to the provisions
of this Article VII if the reallocations provided in paragraphs G and H had not
occurred. 
        
                     ARTICLE VIII. APPLICATION OF PROCEEDS

        All Net Proceeds will be used solely for the conduct of Partnership
operations. 


        In view of the fact that any Partnership activities will not commence
until sales are closed and Partnership operations commence, Benton and EPC
reserve the right to change the estimated allocation of Proceeds, as described
below, in the best interest of the Partnership.  However, it is anticipated
that the Net Proceeds will be applied by the Partnership, on the basis of
approximately the following percentages:

         Notwithstanding the foregoing, Benton and EPC reserve the right to
vary substantially the percentage of Net Proceeds allocated towards the various
activities described above, depending upon the total amount of Proceeds raised
by Benton,  EPC and others from offerings which will raise funds to participate
on the same Prospects as that anticipated to be acquired, developed or reworked
by this Partnership.
                         

            ARTICLE IX. TERM AND CONVERSION OF GENERAL PARTNER UNITS
         

         A.      The term of the Partnership will commence on the date of
execution of this Agreement, and will continue until December 31, 2039, and will
terminate at such earlier time as all of the interests and properties acquired
for the Partnership have been fully depleted, disposed of, sold or abandoned,
unless sooner terminated as set forth in Article XV or XVII of this Agreement.

         The calendar year is the Partnership's fiscal year, subject to change
by Benton and EPC.
        
         B.      As soon as practicable after the completion of the
Partnership's drilling activity, and subject to the receipt of the opinion of
counsel described below, the General Partner Units shall be converted to
Limited Partner Units.  Such conversion shall occur automatically upon
compliance with this section.  All other rights and obligations under this
Agreement shall not be affected by such conversion.  Prior to any such
conversion, Benton and EPC shall obtain an opinion of tax counsel to the
Partnership to the effect that such conversion would not result in any material
adverse federal tax consequences to the Partnership or the General Partners. In
order to accomplish such conversion, Benton and EPC will (i) amend this Limited
Partnership Agreement with such changes therein or amendments thereto as are
deemed appropriate by Benton and EPC and that do not adversely affect the
General Partners, (ii) file an amended Certificate of Limited Partnership with
the Secretary of State for the State of California and (iii) take such other
actions as are necessary or appropriate to accomplish conversion of the General
Partner interests. Notwithstanding the foregoing, Benton and EPC shall not be
obligated to cause 

                                      12
<PAGE>   16

conversion of the Partnership or may delay such conversion if Benton
and EPC or their tax counsel determine that conversion at that time would not
be in the best interests of the General Partners.

              ARTICLE X. RIGHTS AND OBLIGATIONS OF BENTON AND EPC

        A.      Benton and EPC shall be the Co-Managing General Partners of the
Partnership and as such shall conduct, direct and exercise full control over
all activities of the Partnership.  Generally, Benton shall be primarily
responsible for all of the Partnership's oil and gas activities and EPC shall
be primarily responsible for all the Partnership's administrative activities.
In order to carry out the purposes of the Partnership as set forth in Article
III of this Agreement all Participants agree that Benton and EPC have the
rights and obligations set forth below.

                (1)      Benton may purchase or sell any oil and gas interest
         and may execute on behalf of the Partnership any and all documents or

         amendments thereto, which relate to the affairs of the Partnership;

               (2)       EPC shall maintain complete and accurate books of
         account for the Partnership; said books shall be kept at the principal
         office of the Partnership and shall be open to inspection after
         reasonable notice and request by any Partner or his authorized
         representative, at his own expense, at any time during the ordinary
         business hours;

               (3)       Within one hundred twenty (120) days after the end of
         the fiscal year, EPC shall provide each Participant on an annual
         basis, commencing at the end of the second full year of Partnership
         operations, an independent petroleum engineer's appraisal of the
         status of the properties;

               (4)       EPC shall provide each Participant with an annual
         report (copies of which, together with a report on oil and gas
         reserves and a tax information report, shall be furnished to
         appropriate state securities administrators, as required) within
         ninety (90) days after the close of the Partnership's fiscal year,
         containing the following information:

                        (a)     Financial statements, including the balance
                 sheet and statements of operations, Partners' equity and
                 changes in financial position, prepared in accordance with
                 generally accepted accounting principles and accompanied by an
                 auditor's report containing the opinion of an independent
                 certified public accountant;

                                      13
<PAGE>   17
                        (b)        A description of each Prospect in which the
                 Partnership owns an interest, including the cost, location,
                 number of acres under lease and interest owned by the
                 Partnership, except that succeeding reports will contain only
                 material changes from the preceding report; 

                        (c)      A summary itemization by type and/or
                 classification of the total fees, reimbursements and
                 compensation paid by the Partnership, or indirectly on behalf
                 of the Partnership, to Benton, EPC, or their Affiliates during
                 the period; and 

                        (d)       A schedule reflecting the total Partnership
                 costs, and where applicable, the costs pertaining to each
                 Prospect, the costs paid by Benton and the costs paid by the
                 Participants, the total Partnership revenues, the revenues
                 received or credited to Benton, and the revenues received or
                 credited to the Participants during the period; 

       (5)       EPC shall furnish a report to each Participant by March 15 of
each year, containing such information as EPC deems necessary for the proper
presentation of federal income tax returns; 

       (6)       EPC shall maintain, at the principal office of the
Partnership, copies of the Partnership's federal, state and local income tax
returns and reports for the three (3) most recent years; 

       (7)       Benton will purchase, at the expense of the Partnership,
liability  and other insurance to protect the Partnership's properties and
business; 

       (8)       Benton and EPC may enter into any agreement for the borrowing
of money from a commercial bank or other lending institution for payment of
expenses of drilling and completion activities on wells started with Proceeds
and for payment of General and Administrative Expenses, including the purchase
and lease of oil and gas properties or equipment, and are authorized to assign
any portion of, or all of, the Partnership's properties and revenues therefrom
for the purpose of securing any such borrowed money; provided, however, that
such borrowing shall not exceed, in principal amount, twenty-five percent (25%)
of the Proceeds plus all paid assessments and providedthat in no event will the
lender have the election to convert its position as creditor into an equity
interest in the Partnership or in Benton, EPC or in any of their Affiliates;
                 
       (9)      Benton and EPC may, in the sole exercise of their discretion,
make unsecured loans and advances to the Partnership at Benton's and EPC's
interest cost and may otherwise borrow money and assign to the lender
Partnership properties and production therefrom as security; and, provided
further, that the interest on loans and advances made by Benton and EPC or
their Affiliates shall not exceed the amounts which 

                                      14
<PAGE>   18



would be charged by unrelated banks (without regard to financial
abilities or guarantees) on comparable loans for the same purpose, and no fees,
points or other financing charges will be charged to the Partnership by Benton,
EPC or their Affiliates; 

       (10)      In the states where the Partnership conducts activities, EPC
may file any necessary instruments required to qualify the Partnership to do
business in the particular state as a Limited Partnership, or to cause the
limited partnership status of the entity to be recognized;
                 

       (11)      Benton may cause title to Partnership property to be held in
the name of Benton or an Affiliate, or the Partnership or a nominee chosen by
Benton; provided, that if property is held in the name of Benton, an Affiliate
or a nominee, an unrecorded assignment to the Partnership shall be made and
maintained in the Partnership's files and, provided further, that if it is
prohibited from making an assignment of record, the Partnership will enter into
an agreement with the record owner indicating that the properties are being
held for the benefit of the Partnership and are not subject to the debts,
obligations or liabilities of Benton or its Affiliates;
                 

       (12)      Benton and EPC may admit Participants or substituted
Participants without the consent of other Participants; provided, that any
transferee of a Unit will receive a right to share in the profits and capital
of the Partnership but will not be a substituted Participant without the prior
written consent of Benton and EPC and, provided further, that Benton and EPC
will withhold their written consent in the event that it has reasonably
determined in its sole discretion that such substitution could have an adverse
effect on the business activities or the legal or tax status of the
Partnership, under either state or federal law;
                 

       (13)      Benton and EPC may admit one or more additional managing
general partners which may become a successor entity to Benton and EPC and take
action which would have the effect of providing an additional and/or a
successor managing general partner, if the holders of a majority of the Units
outstanding approve; provided, however, that such approval of the holders of
Units shall not be necessary if the additional managing general partner
proposed by Benton or EPC is (1) an Affiliate of Benton or EPC; (2) an entity
with which Benton or EPC has merged; or (3) a person or entity that has
purchased all or substantially all the assets of Benton or EPC;
                 

       (14)      EPC may call for a vote of the Participants to be taken on the
items set forth in Article XV;

                                      15
<PAGE>   19

       (16)      EPC and Benton may amend the Agreement, including amending the
Agreement to alter the Partnership's form so that it becomes a different type
of business entity, for business and tax reasons, subject to the provisions of
Article XV;

       (17)      EPC and Benton may do any and all things necessary or
appropriate in order to accomplish the purpose of the Partnership, subject to
the provisions of this Agreement;

       (18)      EPC and Benton may conduct other oil and gas drilling and
acquisition programs or income programs which may commence prior to, during or
subsequent to the Partnership;

       (19)     Benton may purchase assets from the Partnership in connection
with a dissolution of the Partnership, at a price which is the greater of the
then fair market value (which term shall mean the value of the assets as
determined by an independent oil an gas engineer) or the highest bona fide
offer for such assets by a third party, if any, regardless of any difference
between such fair market value and the original cost to the Partnership of such
assets (subject to the approval of a majority in interest of the Participants
if the asset represents five percent (5%) or more of the value of the assets of
the Partnership);  

       (20)      EPC may make any and all elections for purposes of federal,
state or local income taxes that it deems appropriate; and 
         
       (21)   Benton and EPC may submit a partnership claim or liability to
arbitration or reference, assign the Partnership property and trust for
creditors or on the assignee's promise to pay the debts of the partnership,
confess a judgment or dispose of the goodwill of the Partnership for adequate
consideration.  

B.      Benton and EPC shall have no authority on behalf of the Partnership or 
themselves to:

       (1)       Do any act in contravention of this Agreement;

       (2)       Use Partnership property or commingle any Partnership bank
accounts or monies with funds of Benton, EPC or their Affiliates, or to make
advances to Benton, EPC or its Affiliates, except where necessary to secure tax
benefits of prepaid drilling and completion costs, and in no event will such
advances include non-refundable payments for capital completion costs prior to
the time that a decision is made that the well warrants such equipment;

       (3)       Take any action with respect to Partnership assets or property
which does not primarily benefit the Partnership, including, among other
things, the utilization of Partnership funds as compensating balances for their
own benefit, and the commitment of future production if not in the best
interests of the Partnership;

                                      16
<PAGE>   20
       (4)       Make any loans of Partnership funds to Benton, EPC or their
Affiliates;
        
       (5)       Make or institute any marketing arrangements or other
relationships affecting the property of the Partnership where the benefits are
not fairly and equitably apportioned according to the respective interests of
all parties; or
                 
       (6)       Knowingly enter into any arrangements involving working
interests in any oil and gas property which commit the working interest to be
held in an entity which limits the liability of the Participants as to the
working interest so as to cause the working interest to be considered a passive
activity so that losses from the working interest may only offset passive
activity income as set forth in Section 469 of the Code.

C.      The following prohibitions and restrictions shall be applicable to
Benton:

       (1)       If Benton sells, transfers or conveys all or any portion of a
lease to the Partnership, Benton must, at the same time, sell, transfer, or
convey to the Partnership an equal proportionate interest in all its other
leases in the same Prospects.  If Benton or any Affiliate of Benton
subsequently proposes to acquire a lease on a Prospect in which that
Partnership owns an interest, or on a Prospect abandoned by the Partnership
within one (1) year preceding such proposed acquisition, Benton or its
Affiliate shall offer to the Partnership an equivalent interest in such lease
as the Partnership had in the Prospect before the proposed acquisition, or
before the abandonment; and, if cash or financing is not available to enable
the Partnership to acquire such interest, neither Benton nor any of its
Affiliates shall acquire the lease.  For the purposes of this paragraph, the
term "Affiliate" shall not include another partnership whether the interest of
the Benton is identical to, or less than, Benton's interest in the Partnership. 
The restrictions described in this paragraph cease with regard to the
Partnership five (5) years after the Partnership's formation.  The geological
limits of the Prospect shall be enlarged or contracted on the basis of
subsequently acquired geological data to define the productive limits of a
reservoir, and must include all of the acreage determined by the subsequent
data to be encompassed by such reservoir; provided, however, that the
Partnership shall not be required to expend additional funds unless they are
available from the initial capitalization of the Partnership or if Benton
believes it is prudent to borrow for the purpose of acquiring such additional
acreage.  If the geological limits of a Prospect, as so enlarged, encompass any
interest held by Benton or an Affiliate, that interest will be sold to the
Partnership in accordance with the provisions of this Article;
                 

       (2)       A sale, transfer, or conveyance to the Partnership of less
than all of the ownership of Benton or its Affiliates in any portion of a lease
(the "Subject Portion") is prohibited unless the interest retained by Benton or
its Affiliates is a working interest, the respective obligations of Benton or
its Affiliates and the Partnership to pay costs with respect to the Subject
Portion are proportionate to their respective working interests after the
transfer, and Benton's or its Affiliates' interest in the revenues does not
exceed any amount proportionate to its retained working interest.  Benton or
its Affiliates may not

                                      17
<PAGE>   21
retain any overrides or other burdens on the Subject Portion, and may
not enter into any Farmout arrangements with respect to its retained interest,
except to nonaffiliated third parties or other partnerships sponsored by
Benton.  For the purposes of this paragraph, the term "Affiliate" shall not
include another partnership where the interest of Benton is identical to, or
less than, Benton's interest in the Partnership.

       (3)       Purchases and sales of leases among oil and gas partnerships
sponsored by Benton are prohibited except for transactions between the
Partnership and another partnership for which Benton or any of its Affiliates
acts as sponsor, whereby a lease is transferred in exchange for the
transferee's obligation to conduct oil and gas drilling activities on such
lease, or the property is operated pursuant to a joint venture among such
partnerships, which are permitted only if the respective obligations and
revenue sharing of all parties to the transaction are substantially the same
and the compensation arrangement of Benton and any Affiliate is the same in the
Partnership and each such partnership or, if different, the aggregate
compensation of Benton and its Affiliates therefrom does not exceed the lowest
compensation Benton and its Affiliates would have received through any one of
the relevant partnerships, taking into consideration varying participation by
Benton or its Affiliates.
                 
       (4)      Partnership funds may not be used to prove up adjacent
properties in any Prospect belonging to Benton or its Affiliates.
                 
       (5)      Benton and its Affiliates (other than other public or private
partnerships and programs) are not permitted to purchase any producing leases
from the Partnership, but this prohibition will not prohibit the purchase by
Benton or an Affiliate of such producing leases in connection with a
dissolution or sale of substantially all of the assets.  If any non-producing
lease is to be purchased from the Partnership by Benton or its Affiliates, such
purchase must be at the higher of its fair market value or the cost of such
lease to the Partnership.
                 
       (6)     Benton and its Affiliates (excluding partnerships in which
Benton's interest is equal to or less than its interest in the Partnership) may
not acquire, retain, or drill for their own account any oil and gas interest on
any Prospect in which the Partnership has an interest, except as permitted by
the terms of clause (2), above. This restriction also continues for one (1)
year after abandonment as to any Prospect by the Partnership.  If a Prospect is
enlarged by reason of subsequently obtained geological data to include an
interest held by Benton or its Affiliates, a portion of the interest shall be
sold to the Partnership concerned in accordance with the terms of clause A.,
above.
                                  
       (7)     Benton may never profit by drilling in contravention of its
fiduciary obligation to the Partners.  All services provided to the Partnership
by Benton or its Affiliates will be embodied in a written contract which
precisely describes the services to be rendered and all compensation to be
paid.

                                      18
<PAGE>   22
                  ARTICLE XI. COMPENSATION OF BENTON AND EPC

        Benton maintains a staff of geologists, engineers and land personnel 
who are responsible for screening and acquisition of leases and for conducting
drilling and producing operations.  The costs incurred in maintaining these
departments, including salaries of personnel, are allocable in part to the
Partnership's activities and are included in Partnership Costs.  Such costs
shall be paid or reimbursed by the Partnership out of Proceeds or revenues.
        
        Benton and EPC will be reimbursed for an allocable portion of actual
General and Administrative Expenses, which will be paid as incurred and which
includes actual and necessary costs of their offices, including office
overhead, salaries, telephone, secretarial, travel, costs of accounting
services and other costs and expenses not directly related to a specific
Partnership activity.  Such expense reimbursement is estimated not to exceed
three percent (3%) of the Subscriptions during the first twelve (12) months of
operations.  These reimbursements will be subject to audit on an annual basis.

        As set forth in Article VI, Benton and EPC will share in Partnership
revenues in an amount in excess of their contribution to Partnership costs. The
Participants consent to the receipt by Benton, EPC and their Affiliates of the
benefits and profits set forth in this Article.

                    ARTICLE XII. PROTECTION OF THE PARTIES

        In any threatened, pending or completed action, suit or proceeding to
which the Co-Managing General Partners were or are a party or is threatened to
be made a party by reason of the fact that they were or are a Co-Managing
General Partner of the Partnership (other than an action by or in the right of
the Partnership) involving any alleged cause of action for damages arising from
the performance of oil and gas activities, including exploration, development,
completion, operation, or other activities relative to management and
disposition of oil and gas properties or production from such properties, the
Partnership will indemnify the Co-Managing General Partners against expenses,
including attorneys' fees, judgments and amounts paid in settlement actually
and reasonably incurred by them in connection with such action, suit or
proceeding if they acted in good faith and in a manner they reasonably believed
to be in or not opposed to the best interests of the Partnership, and provided
that their conduct does not constitute negligence, misconduct, or a breach of
their fiduciary obligations to the Participants.  The termination of any
action, suit or proceeding by judgment, order or settlement shall not, of
itself, create a presumption that Benton or EPC did not act in good faith and
in a manner which they reasonably believed to be in or not opposed to the best
interests of the Partnership.


        In any threatened, pending or completed action or suit by the
Partnership in the right of the Partnership, to which a Co-Managing General
Partner was or is a party or is threatened to be made a party, involving an
alleged cause of action by a Participant(s) for damages arising from the
activities of a Co-Managing General Partner in the performance of management of
the internal affairs of the Partnership as prescribed by this Agreement, the
Partnership will indemnify 

                                      19

<PAGE>   23
the Co-Managing General Partner against expenses, including attorneys'
fees, actually and reasonably incurred by it in connection with the defense or
settlement of such action or suit if it acted in good faith and in a manner it
reasonably believed to be in or not opposed to the best interests of the
Partnership, as specified in this paragraph, except that no indemnification
shall be made in respect of any claim, issue or matter as to which a
Co-Managing General Partner shall have been adjudged to be liable for
negligence, misconduct, or breach of fiduciary obligation in the performance of
its duty to the Partnership unless and only to the extent that the court in
which such action or suit was brought shall determine upon application, that,
despite the adjudication of liability, but in view of all circumstances of the
case, a Co-Managing General Partner is fairly and reasonably entitled to
indemnity for such expenses which the court shall deem proper.

        To the extent that a Co-Managing General Partner has been successful on
the merits or otherwise in defense of any action, suit or proceeding referred
to above, or in defense of any claim, issue or matter therein, the Partnership
shall indemnify a Co-Managing General Partner against the expenses, including
attorneys' fees, actually and reasonably incurred by it in connection
therewith.  Any such indemnification of a Co-Managing General Partner shall be
prohibited unless the Co-Managing General Partner has determined in good faith
that the course of conduct which caused the loss or liability was in the best
interest of the Partnership; that such liability or loss was not the result of
negligence or misconduct by a Co-Managing General Partner; and that
indemnification of a Co-Managing General Partner or its Affiliates will not be
allowed for any liability imposed by judgment, and costs associated therewith,
including attorneys' fees, arising from or out of violation of state or federal
securities laws associated with the offer and sale of Partnership Units.
Indemnification will be allowed for settlements and related expenses of a
lawsuit alleging securities law violations, and for expenses incurred in
successfully defending such lawsuits, provided that a court either:  (a)
approves the settlement and finds indemnification of the settlement and related
costs should be made or (b) approves indemnification of litigation costs if a
successful defense is made.

        Any indemnification, unless ordered by a court, shall be made by the
Partnership only as authorized in the specific case and only upon a
determination by independent legal counsel in a written opinion that
indemnification of a Co-Managing General Partner is proper in the circumstances
because a Co-Managing General Partner has met the applicable standard of
conduct set forth above.

        The indemnification of a Co-Managing General Partner shall be limited
to and recoverable only out of the assets of the Partnership and not against
any Limited Partner or General Partner and indemnification of the Co-Managing
General Partners as to a third party is only with respect to such loss,
liability or damage not otherwise compensated for by insurance carried for the
benefit of the Partnership.

        The Partnership may not incur the cost of that portion of insurance
which insures a Co-Managing General Partners from any liability as to which the
Co-Managing General Partner is prohibited from being indemnified under this
Article.  
                                      20
<PAGE>   24
        The Participants hereby agree that each shall be solely and
individually responsible only for their pro rata share of the liabilities and
obligations of the Partnership, and any Participant who incurs liability in
excess of his pro rata share shall be entitled to contribution from the other
Participants.  Pursuant thereto, each Co-Managing General Partner further
agrees to indemnify each Participant from paying any liabilities or obligations
of the Partnership in excess of such Participant's capital contribution.
Furthermore, although the Participants may be personally liable for the
liabilities and obligations of the Partnership, all such liabilities and
obligations shall be paid or discharged first with Partnership assets
(including insurance proceeds) before the Participants shall be obligated to
pay or discharge any liability or obligation with their personal assets.

                         ARTICLE XIII. RELATED PARTIES
 
        Benton and EPC and their Affiliates or related persons or entities may
be engaged or employed by the Partnership to render or perform services for the
Partnership and/or may sell property of any kind or description to it, or may
otherwise engage in transactions with the Partnership.  All such engagements,
employments and other transactions shall not be invalidated by reason of any
such relationships so long as such person is engaged, independently of the
Partnership and as an ongoing business in rendering such services or selling
such equipment and supplies to a substantial extent to other persons and such
prices and terms are not higher than those normally charged in the same
geographic area by unaffiliated persons or companies dealing at arm's length.
If the person is not engaged in business as provided above, then the price of
such services shall be the cost of such services, equipment or supplies to such
person or the competitive rate in the geographical area, whichever is less.
Benton or EPC may be presently conducting or may conduct in the future other
oil and gas income, drilling and acquisition programs which may commence during
or subsequent to this Partnership.  All contracts entered into between the
Partnership, Benton, EPC and their Affiliates or related persons or entities
shall be terminated without penalty on not less than thirty (30) days' written
notice by the Partnership or on sixty (60) days' written notice by Benton, EPC
or their Affiliates.

        The leases transferred to the Partnership by Benton or its Affiliates
shall be sold at Cost unless Benton believes that the appraised value is
substantially lower than Cost.  In such a case the value of the lease will be
determined by an independent appraiser and sold at the lower of Cost or
appraised value.

                 ARTICLE XIV. RESTRICTIONS ON TRANSFERABILITY

        No Participant shall have the power to sell, assign or transfer his
interest in the Partnership or to cause a transferee to become a substitute
Participant except upon the written consent of Benton and EPC.  Each
Participant specifically agrees to the admission of any substitute Participant
as a Partner when consented to by Benton and EPC.  Benton and EPC shall review
any proposed transfer and shall withhold their consent in the event they
reasonably determine, in their sole discretion, that such substitution could
have an adverse effect on the 
                                      21
<PAGE>   25
business activities or the legal or tax status of the Partnership or
the remaining partners under either state or federal law.

        Benton and EPC may sell, assign, transfer, pledge or encumber all or
any portion of their rights to receive revenues as a Managing General Partner
under this Partnership Agreement; provided, however, that the assignment of
such revenue interest shall not affect Benton's and EPC's other rights and
obligations pursuant to this Agreement.

        In addition to the restrictions upon substitution of an additional
Participant, a Participant may not sell his rights to profits and capital in
the Partnership without furnishing Benton and EPC with a copy of the offer to
buy such interest and giving Benton and EPC the prior right for a period of ten
(10) days after receipt of written notice, to purchase such interest on the
terms contained in such offer.  In the event Benton and EPC do not exercise
their prior right to purchase such interest in profits and capital within a ten
(10) day period or notify the Participant that such right will not be
exercised, the Participant shall have the right to sell his interest in profits
and capital for a period of forty-five (45) days.  Thereafter, the Participant
shall not sell any part of his interest in profits and capital without again
offering the same to Benton and EPC.  A transferee of a Participant's right to
profits and capital who is not admitted as a Participant is not entitled to any
of the rights of a Participant.  A transferee Participant has no greater right
to terminate the Partnership than his transferor.

        In no event shall any assignee or transferee hold less than one Unit
except by gift or operation of law.

                      ARTICLE XV. RIGHTS, AUTHORITY AND
                         LIABILITIES OF PARTICIPANTS

        A.      RIGHTS

        By a majority vote of the outstanding Units, the Participants shall
        have the right to:

               (1)       Remove Benton, EPC and/or any successor Managing
         General Partner; terminate all contracts between the Partnership and
         Benton, EPC and their Affiliates; allow Benton, EPC or their
         Affiliates to remove all of their property interests in the
         Partnership; and select a substitute managing general partner or
         additional general partner to continue the business of the
         Partnership;

               (2)       Amend the Agreement, subject to the written consent of
         Benton and EPC concerning matter affecting their interests in profits,
         losses, credits and property;

               (3)       Terminate the Partnership;

               (4)       Approve the sale or exchange of all or substantially
         all of the assets; and/or
                                      22
<PAGE>   26
              (5)       Approve the admission of an additional general partner
        proposed to be admitted as a Managing General Partner by Benton and EPC,
        subject to the right of Benton and EPC to admit certain parties as
        general partners without the consent of the Participants, as provided
        in paragraph 13 of Article X. 
        
        Either the Participants, upon the written request of ten percent (10%)
of the outstanding Units, or Benton or EPC can cause a vote to be taken with
respect to the matters referred to above.  Notice of a meeting of the
Participants will be mailed to the Participants within ten (10) days of the
receipt of such written notice unless compliance with federal or state laws or
regulations requires additional time.  A meeting will be held within sixty (60)
days of the mailing of the notice.  The presence, in person or by proxy, of the
holders of a majority of the Units outstanding shall constitute a quorum and
Participants may vote in person or by proxy at any such meeting.  If a quorum
shall not be present or represented at any meeting, a majority of the holders
of Units entitled to vote at the meeting, who are present in person or
represented by proxy, may adjourn the meeting from time to time, without notice
other than announcement at the meeting, until a quorum shall be present or
represented.  At any reconvening of an adjourned meeting at which a quorum
shall be present or represented, any business may be transacted which could
have been transacted at the original meeting if a quorum had been present or
represented.  No matters that would constitute taking part in control of the
Partnership by the Participants shall be considered at any meeting.  In order
to facilitate the above rights, each Participant shall have a right to receive
by mail the complete list of names, addresses and interests of all other
Participants, upon written request to EPC. 

        Any action that may be taken at a meeting of the Participants may be
taken without a meeting if a consent in writing setting forth the action so
taken is signed by Participants owning not less than the minimum Units that
would be necessary to authorize or take such action at a meeting at which all
the Participants were present and voted.  Prompt notice of the taking of action
without a meeting shall be given to the Participants who have not consented in
writing. 

        Benton and EPC shall have the right to amend the Agreement; provided,
that the Agreement shall not be amended by Benton and EPC in any material
respect which would adversely affect the rights of the Participants except by
the affirmative vote of not less than a majority of the outstanding amount of
Partnership interests. 

        In the event that the Participants vote to remove Benton or EPC and
substitute a new Managing General Partner pursuant to Paragraph A of this
Article, the Partnership or the new Managing General Partner shall purchase the
entire interest of Benton or EPC, including their interest in capital and
revenues on an assumed dissolution basis, at a price determined by mutual
agreement or by independent appraisal by a petroleum engineer selected by
mutual agreement.  Such purchase shall provide for payment in full, or
assignment to Benton or EPC of a direct interest in each Partnership asset
and/or liability equal to their then interest in revenue and capital as
determined above.  Such payment or assignment shall occur at the time of
amendment of the Agreement and substitution of the new Managing General
Partner.
                                      23
<PAGE>   27
        B.      AUTHORITY
        
        No Participant has the power to manage or conduct Partnership business,
to act in the ordinary course of business for the Partnership or to sign for or
to bind the Partnership or any of its Partners and no such actions will be
considered to have been authorized by the other Partners.

        C.      LIABILITY

        No Limited Partner shall be personally liable for any of the debts of
the Partnership or any of the losses thereof; provided, however, that the
amount committed by him to the capital of the Partnership, any return thereof,
and his interest in the Partnership's undistributed profits shall be subject to
liability.  Additionally, a Limited Partner may be liable for wrongfully
distributed profits and interest on distributions in return of capital.

        A Partner receives a return of his contribution to the extent that a
distribution to him reduces his share of the fair value of the net assets of
the Partnership below the value, as set forth in the Certificate of Limited
Partnership, of his contribution that has not been distributed to him.  If a
Limited Partner receives the return of any part of his contribution without
violation of this Agreement or the California Revised Uniform Limited
Partnership Act, he shall be liable to the Partnership for one (1) year after
the return for the amount of the returned contributions but only to the extent
necessary to discharge the Partnership's liabilities to creditors who extended
credit to the Partnership during the period the contribution was held by the
Partnership.  If a Limited Partner receives the return of any part of his
contribution in violation of this Agreement or the California Revised Uniform
Limited Partnership Act, he shall be liable to the Partnership for six (6)
years after the return for the amount of the contribution wrongfully returned.

        D.      MISCELLANEOUS

        No Participant has any right of repayment of his contributions to the
Partnership except as provided in Articles VI and XVII.  Participants will
share in losses as provided in Articles V and VII and will share in profits as
provided in Article VI.  Further, the Participants have no right to vote on any
Partnership matters except as set forth in this Agreement.  Participants agree
that they will not request a decree of dissolution from a court until a
majority vote of the outstanding Units of Participants has approved such
decree.

                   ARTICLE XVI. WITHDRAWAL OF BENTON OR EPC

        A.      EVENTS REQUIRING CONSENT OF ALL PARTNERS TO AVOID WITHDRAWAL

        Except as approved by the specific written consent of all Partners at
the time, Benton, EPC or any other General Partner shall cease to be a General
Partner of the Partnership upon the happening of any of the following events of
withdrawal:  (1) Benton, EPC or a General Partner withdrawing from the
Partnership by giving one hundred twenty (120) days written notice to the other
Partners, provided that the Partnership has completed its Proven Producing
Property

                                      24

<PAGE>   28
acquisition, Recompletion Well activities and drilling of Partnership
Wells, and provided that the withdrawing Partner pays all expenses incurred as
a result of its withdrawal; (2) Benton, EPC or a General Partner is removed as
a General Partner in accordance with the terms of the Agreement; (3) in the
case of a General Partner who is a natural person, the death or adjudication of
incompetency of a General Partner; (4) in the case of a General Partner who is
acting as a General Partner by virtue of being a trustee of a trust, the
termination of the trust, but not merely the substitution of a new trustee; (5)
in the case of a General Partner which is a separate partnership, the
dissolution and commencement of winding up of the partnership; (6) in the case
of Benton, EPC or a General Partner that is a corporation, the dissolution of
the corporation or the revocation of its charter; (7) in the case of an estate,
the distribution by the fiduciary of the estate's entire interest in the
Partnership; or (8) in the case of a General Partner that is any other legal
entity, the cessation of the legal existence of the legal entity.

        Upon withdrawal, a General Partner other than Benton or EPC shall
retain all rights to its proportionate share of revenues and capital, but shall
cease to have any vote or engage in any other activities as a General Partner.
The withdrawing General Partner will have the right to transfer his interest
subject to provisions of Article XIV hereof.

        B.      EVENTS NOT CAUSING WITHDRAWAL

        Neither Benton, EPC nor any other General Partner shall cease to be a
general partner of the Partnership upon the happening of any of the following
events:  (1) Benton, EPC or a General Partner makes an assignment for the
benefit of creditors; (2) Benton, EPC or a General Partner files a voluntary
petition in bankruptcy; (3) Benton, EPC or a General Partner is adjudicated
bankrupt or insolvent; (4) Benton, EPC or a General Partner files a petition or
answer seeking for itself any reorganization, arrangement, composition,
readjustment, liquidation, dissolution or similar relief under any statute, law
or regulation; (5) Benton, EPC or a General Partner files an answer or other
pleading admitting or failing to contest the material allegations of a petition
filed against it in any proceeding of a type described in (4), above; (6)
Benton, EPC or a General Partner seeks, consents to or acquiesces in the
appointment of a trustee, receiver or liquidator of Benton, EPC or a General
Partner or of all or any substantial part of Benton's, EPC's or a General
Partner's properties; or (7) one hundred twenty (120) days have elapsed after
the commencement of any proceeding against Benton, EPC or a General Partner
seeking reorganization, arrangement, composition, readjustment, liquidation,
dissolution or similar relief under any statute, law or regulation and the
proceeding has not been dismissed; or within ninety (90) days after the
appointment, without Benton's, EPC's or a General Partner's consent or
acquiescence, of a trustee, receiver or liquidator of Benton, EPC or a General
Partner or of all or any substantial part of its properties, the appointment is
not vacated or stayed, or within ninety (90) days after the expiration of such
a stay, the appointment is not vacated.

<PAGE>   29
                          ARTICLE XVII.  DISSOLUTION

        A.       The parties specifically agree that the retirement, 
resignation, expulsion, death, incompetency, bankruptcy, insolvency,
dissolution, withdrawal, conveyance of the interest of a Participant, or
admission of a new partner, or express decision of a Participant shall not
dissolve the Partnership.  In such event, the heir, legal representative,
successor or assign of such Participant, as the case may be, shall become an
assignee of such Participant's interest.  Such assignee shall not have the
rights of a substituted Participant, unless, with the approval of EPC, such
heir, legal representative, successor or assign shall execute an addendum to
this Agreement, agreeing to be bound by all of the terms and conditions hereof,
and to assume all of the obligations of the deceased or incapacitated
Participant hereunder.  When a Participant dies or retires and the business is
continued, the Participant or his estate has no right to require the
Partnership or the remaining Participants to make an evaluated purchase of his
Partnership interest.
        
        B.       If, notwithstanding the intent of the Partners as set forth in
A., above, any event listed in A. results in the dissolution of the
Partnership, such dissolution shall be considered in contravention of the
Agreement, and the Partnership shall be continued or reconstituted.  In the
event that the Partnership is dissolved, despite the intention of the Partners,
through any acts pursuant to A., above, the Partners agree that EPC may take
any action which it deems necessary or appropriate to continue the Partnership
or to reform the Partnership on terms as identical as possible to this
Agreement.  In the event that EPC causes a continuation or reformation of the
Partnership, the liability of all Partners will be deemed to continue
uninterrupted.
    
        C.       The following actions shall cause a dissolution of the
Partnership, provided that Benton or EPC cannot take any voluntary action to
cause dissolution between the time it receives notice from the Participants of
their intent to remove a Co-Managing General Partner and the completion of the
voting and the actions, if any, authorized by the voting:
 
               (1)       The transfer or assignment of the entire interest of
         Benton or EPC unless a remaining Managing General Partner agrees to
         continue the Partnership;
 
               (2)       The written vote or consent by Participants
         representing a majority of the outstanding Units and as further
         provided by Article XV;

               (3)       The conduct of the Partnership becoming unlawful;

               (4)       The disposition of all or substantially all of the
         assets of the Partnership;

               (5)       The expiration of the term of the Partnership as
         provided in Article IX;

               (6)       An event of withdrawal or expulsion of Benton and EPC,
         unless at the time there is at least one other Partner who carries on
         the business of the Partnership; provided, that the Partnership is not
         dissolved and is not required to be wound up by


                                      26
<PAGE>   30

        reason of any event of withdrawal if, within ninety (90) days after the
        withdrawal, all remaining parties agree in writing to continue the
        business of the Partnership and to the appointment of one or more
        managing general partners if necessary or desired; or 
        
              (7)       The entry of a decree of judicial dissolution. 

        Any dissolution caused by an event other than those 
events listed above as causes of dissolution will be considered a dissolution 
in contravention of this Agreement.
        
        D.       Upon dissolution and winding up of the Partnership, all of the
assets of the Partnership may be liquidated, and all Partnership assets shall
be applied in the following order:
                          
                       (a)      To creditors, including Partners who are
                 creditors, to the extent permitted by law, in satisfaction of
                 liabilities of the Partnership other than liabilities for
                 distributions to Partners; then
           
                       (b)      To Partners and former Partners in satisfaction
                 of their rights to interim distributions or distributions upon
                 withdrawal; then

                       (c)      To Partners, to the extent of positive capital
                 accounts, first for the return of their capital account
                 balances and, secondly, respecting their Partnership
                 interests, in the proportions in which they then share in cash
                 distributions. 

        With respect to the distributions made in liquidation, Partners who are
not otherwise creditors shall not have the status of and be entitled to the
remedies available to a creditor of the Partnership.  In the event of a
distribution of assets in kind, all assets to be distributed to the
Participants shall be distributed to an independent trustee for all of the
Participants who shall hold title for the benefit of such Participants, collect
and distribute to such Participants all of the net income from such properties
and/or sell such properties as such independent trustee deems to be in the best
interests of the Participants and at the expense of such Participants.  The
independent trustee shall operate the liquidating trust arrangement for so long
as is necessary to sell or exchange Partnership Assets for cash on terms which
the trustee deems to be in the best interest of the Participants. 

        In the event the liabilities of the Partnership exceed its assets upon
liquidation, the Partners must contribute funds to the Partnership in the ratio
of their negative capital accounts until negative capital accounts are
eliminated.  In the event any Partner fails to make the required contribution,
Benton agrees to pay the amounts required and no Participant shall have any
liability for the amounts not contributed by other Participants. 

        Upon termination of the Partnership, a statement shall be prepared by
the certified public accountant employed by the Partnership setting forth the
assets and liabilities of the Partnership and the distribution of cash or
property of the Partnership as prescribed above, and a copy of such statement
shall be furnished to each Partner within ninety (90) days after completion of
winding up of Partnership business.

                                      27

<PAGE>   31
        For purposes of the liquidation of Partnership assets, the discharge of
its liabilities, and the distribution of the remaining funds and/or assets
among the Partners as above described, in the event that all Partnership
property is not sold, or in the sole discretion of Benton cannot be sold so
that distributions in kind to the Partners are appropriate or necessary, Benton
and EPC shall cause all Partnership assets to be appraised by a competent,
qualified appraiser.  Any excess of fair market value, as evidenced by such
appraisal, over book value of any Partnership assets and any excess of book
value over such fair market value of any Partnership assets shall be deemed
gains or losses of the Partnership, as the case may be, and subject to the
provisions of Articles V and VI, above, Benton and EPC shall have the authority
on behalf of the Partnership to sell, convey, exchange, buy back, or otherwise
transfer the assets of the Partnership upon such terms and conditions as it
determines appropriate subject to the terms of this Agreement.  A reasonable
time shall be allowed for the orderly liquidation of the assets of the
Partnership to minimize normal losses of the liquidation period.  Any return of
all or any portion of the contributions by a Partner to the capital of the
Partnership shall be made solely from or out of Partnership assets and Benton
and EPC shall not be personally liable for any such return.

                   ARTICLE XVIII. ASSESSMENTS AND BORROWINGS

        The Partners are subject to the payment of one or more assessments as
additional capital contributions to the Partnership.  No assessment shall be
made, however, unless and until all original Proceeds have been expended or
committed.  The failure of one or more Participants to pay any assessment does
not result in personal liability, but will result in the dilution of such
Participants' interest in all Partnership revenues and costs.  A Participant's
interest in the Participants' share of Partnership revenues is based on the
ratio that the sum of his Subscription and paid assessments bears to the total
sum of all Participants' Subscriptions and assessments paid by all Participants
(including Benton and EPC to the extent they pay non-consenting Participants'
shares of assessments).  The failure of a Participant to pay his share of an
assessment will reduce this ratio accordingly, as of the closing of the
pre-assessment or assessment period.  Costs paid out of assessments will be
allocated only to those Partners who paid such assessment.  If one or more
Participants fail to pay such assessment, Benton and EPC may contribute the
nonconsenting Participants' shares of such assessment, at their election, which
will proportionately increase the interest of Benton and EPC in all Partnership
revenues and costs, on the same basis as if Benton and EPC were a Participant.
If the Participants fail to pay an amount equal to at least fifty percent (50%)
of the total assessment requested, Benton and EPC have the option of either
returning to the Participants all assessments contributed, or contributing the
non-consenting Participants' shares of such assessment.  If the amount
contributed by the Participants equals or exceeds fifty percent (50%) of the
assessment requested, Benton and EPC may contribute all or a portion of the
non-consenting Participants' shares of such assessment and also may reduce the
Partnership's participation in the Prospect for which the assessment was made
by entering into a farmout agreement with respect to such Prospect.  The
cumulative amount of assessments shall not exceed twenty-five percent (25%) of
the Proceeds of the Partnership.

                                      28

        After the Partnership has expended or committed its Proceeds for
property acquisitions and drilling operations, Benton and EPC may finance
necessary additional operations by Partnership assessments, use of Partnership
revenues, or borrowings.  Assessments may be levied by Benton and EPC only for
the purpose of conducting subsequent operations on Prospects upon which
evaluation had begun during the Partnership's initial operation or on leases
sufficiently related to such Prospects as to merit, in the Co-Managing General
Partners' judgment, additional operations to fully develop those Prospects or
to acquire additional undeveloped leases located on the geological feature or
features of Prospects owned by the Partnership in order to fully develop and
protect its Prospects.

        Benton and EPC will give written notice to each Participant of the
nature and purpose of any assessment, the Participant's proportionate share of
the estimated costs, and the effect of the Participant's not participating in
the assessment.  A Participant may elect to participate in an assessment by
notifying Benton and EPC of his intention to participate and sending the
requested payment by mail within twenty (20) days after Benton and EPC mail the
written assessment notice, unless such period is extended by Benton and EPC. 
Any Participant shall be deemed to have refused to participate in any
assessment by notifying Benton and EPC of his election not to participate or by
failure to pay his share of the assessment when due.  In the event that the
proportionate interests of the Partners change by reason of assessments, solely
for the purpose of allocating costs and revenues, there shall be an interim
closing of the Partnership financial books immediately upon closing of the
assessment period, with all allocations made as of the date of the interim
closing according to the interests of the Partners immediately prior to payment
of the assessments.  The pre-assessment or assessment period closes on the last
day established by Benton and EPC for the payment of an assessment by the
Participants.

        Benton intends to develop the Partnership's Prospects fully through the
initial Proceeds and assessments.  However, no assurance can be made that such
funds will be sufficient.  If such funds are not sufficient, the Partnership
may borrow the necessary funds, may farm out the undeveloped portion of certain
Prospects, or may sell or abandon certain undeveloped leases.  

                        ARTICLE XIX. POWER OF ATTORNEY

        The Participants constitute and appoint Benton and EPC and their
successors and assigns, with full power of substitution, as their true and
lawful representative and attorney-in-fact in their name, place and stead to
make, execute, and sign a partnership agreement which admits the Participants
as such to the Partnership, any amendments thereof required by law and all such
other instruments, documents and certificates or amendments thereto which may
from time to time be required by the laws of the United States of America, the
State of California or any other state in which the Partnership shall determine
to do business, or any political subdivision or agency thereof, to effectuate,
implement and continue the valid subsisting existence of the Partnership.  Such
representative and attorney-in-fact shall not, however, have any right, power
or authority to amend or modify this Agreement when acting in such capacities
except when the amendment is made pursuant to Article XV.

                     ARTICLE IV. CAPITAL OF THE PARTNERS

         A.      CAPITAL CONTRIBUTIONS

                 (1)      Each  Participant has made a capital contribution to
         the Partnership in cash equal to the amount set  forth in the
         Subscription Agreement  submitted to Energy Partners by  the
         Participants and  accepted by Energy Partners. A Participant's
         interest  in the Partnership, including his interest in undistributed
         profits, will be subject to the debts of the Partnership.

                 (2)      Benton and Energy  Partners will make  a capital
         contribution  to the Partnership  as required  to pay  their  share of
         costs as  provided in  Article  V hereof,  and in  return  for such
         payments, Benton, Energy Partners and other General Partners  shall be
         entitled to share in all  items of income,  gain, loss,  deduction  or
         credit  allocated to  the respective  Partners  as provided  in
         Article VI.

                 (3)      Benton and  Energy Partners will  make a capital
         contribution as a  one percent (1%) General Partner.

                 (4)      Each Participant  is  subject to  Assessments  in the
         amount  of up  to  twenty-five percent (25%) of the amount of his
         original capital contribution.

                 (5)      The  Special Limited  Partners shall  not be liable
         for Assessments  or to  make any other capital contributions to the
         Partnership.

         B.      DETERMINATION OF CAPITAL ACCOUNTS

         A  single capital  account shall be  maintained for  each Partner (or
transferee of  a Partner, which transferee shall  succeed  to  the allocable
portion of  the  capital account  of his  transferor,  as of  the effective
date of  the transfer).  The  capital account  for each  Partner  will  be
determined  based on  the Treasury  Regulations  regarding  maintenance of
capital  accounts  promulgated  under  Code  Section  704(b), including
Treasury Regulation    1.704-1(b)(2)(iv)(g).  Generally, these  Treasury
Regulations  provide that capital accounts of  Partners shall be increased  by
(1) the amount  of money contributed by  a Partner to the Partnership, (2)  the
fair  market value  of property  contributed by  a  Partner  to the
Partnership and  (3) allocations to a  Partner of Partnership taxable  income
and gain (or items thereof).  Capital accounts will be decreased by (1) the
amount of money distributed  to a Partner by the  Partnership, (2) the fair
market  value of property  distributed  to a  Partner by  the  Partnership, (3)
allocations  of  Partnership tax  loss  and deduction (or items thereof), and
(4) organizational and syndication costs which are not amortized.

         In the event  of a distribution in  kind of any property,  the capital
accounts of the  Partners shall first  be  adjusted to  reflect the  manner in
which  the  unrealized income,  gain, or  loss inherent  in the property (which
has not  been previously reflected in capital accounts)  would be allocated
among the Partners if there were a taxable disposition of the property at its
fair market value.

         C.      SIMULATED DEPLETION ACCOUNT

         Solely for purposes of maintaining capital accounts, depletion  with
respect to oil and gas properties shall be computed at the Partnership level.
The  Partnership shall compute a simulated depletion  allowance on each  oil or
gas  property  using the  percentage  depletion  method. The  Partnership's
simulated depletion allowance shall reduce the Partners' capital accounts in
the same proportion as such


                                      6
<PAGE>   7
Partners (or their predecessors in  interest) were allocated adjusted basis
with respect to such property.  The aggregate  capital account  adjustments for
simulated  depletion allowances  with  respect  to an  oil or  gas property
shall not exceed the Partnership's adjusted tax basis  in such property. Upon
the  taxable disposition of an oil or gas property by the Partnership, the
Partnership's simulated  gain or loss shall be determined by subtracting its
simulated adjusted basis  in such property from  the amount  realized from such
disposition.  (The Partnership's simulated  adjusted basis  in an oil and  gas
property is determined  in the same manner  as adjusted  tax  basis except
that simulated  depletion  allowances are  taken into  account  instead of
actual depletion  allowances.) Any resultant simulated gain shall  be allocated
to the Partners in  the same manner as that portion of the  amount realized
from such disposition  which exceeds the  Partnership's simulated adjusted
basis in  such property  is allocated  to such  Partners and  shall increase
such Partners'  capital accounts accordingly. Any resultant simulated loss
shall be  allocated to the Partners  in proportion to the  Partners' allocable
shares of the  total amount realized from the disposition of such property
that represents recovery of the  Partnership's simulated  adjusted basis  in
such  property, and  shall  reduce  such Partners'  capital accounts
accordingly.

         D.     INTEREST ON CAPITAL

         No interest shall  be paid on the capital  account of, or on  any
capital contributed by,  any Partner either before or after the time repayment
should be made.

                     ARTICLE V. COSTS CHARGED TO PARTNERS

         For purposes  of determining  liability for  Assessments, sharing  in
distributions  and otherwise  as provided herein, items expended  by the
Partnership shall be charged  as follows, provided that costs paid  out of
Assessments shall only be charged to Partners who paid such Assessments:

         A.     PARTNERSHIP COSTS

         All  Partnership  Well Costs,  including  completion  costs, costs  of
Recompletion  Wells, costs  of acquiring  Proven Producing  Properties, and
geological, geophysical and  seismic costs, and  all Organization and Marketing
Expenses shall be allocated one hundred percent (100%) to the Participants.

         B.     OPERATING COSTS

          The expenses  of operating Partnership Wells  are to be charged  in
the same ratio  that revenues are shared in such  wells, pursuant to paragraph
A  of Article VI. In addition,  operating costs shall include the costs of
recompleting Partnership Wells.

         C.     OTHER COSTS

         All costs  which are not otherwise specifically provided for in
Article V(A) above, including, but not limited  to General  and Administrative
Expenses and  Direct Expenses,  shall be  charged one  hundred percent (100%)
to the Participants.

         Costs  charged  to Participants  and the  Co-Managing  General
Partners  will  be allocated  among the Participants as provided in paragraph C
of Article VI.



                                      7
<PAGE>   8
         D.     LOSS ON SALE OF PARTNERSHIP ASSETS

         If the Partnership sells any  oil and gas property at a price which is
less than its undepleted cost, the Partnership shall charge the loss on such
sale to the Partners in the ratio of their remaining undepleted bases in such
property at the time of sale.

         If the Partnership sells any asset,  other than an oil and gas
property, at a price which is less than its undepreciated  cost, the
Partnership shall charge the loss on such sale to  the Partners who bore the
cost of such asset.

                    ARTICLE VI. ALLOCATION OF REVENUES AND
                            DISTRIBUTIONS OF CASH

         A.     ALLOCATION OF REVENUES

         All Partnership  revenues shall  be  allocated seventy-four  and
one-fourth  percent  (74.25%) to  the Participants, twenty-four  and
three-fourths  percent  (24.75%)  to the  Co-Managing General  Partners and
one percent (1%) to the Special  Limited Partners. For  Partnership purposes,
revenues  shall mean funds  received by the Partnership  from all sources,
except  capital contributions, borrowings,  Assessments and interest  on
subscriptions,  whether occurring  during the  term of  the Partnership  or
occurring  as part  of any  plan of dissolution and liquidation  of the
Partnership; provided, however,  that the portion of the revenues generated by
the taxable  disposition of a Partnership  oil and gas  property that
represents recovery  of its simulated adjusted tax basis therein  will be
allocated to the  Partners in the same proportion  such Partners (or their
predecessors  in interest)  were allocated the basis  of such property
pursuant to paragraph C  of Article IV; provided,  further, that the  portion
of the  revenues generated by the  taxable disposition of  a Partnership asset,
other than  an oil and gas property,  equal to the  Partnership's adjusted tax
basis in such  property shall be allocated to the Partners in the same
proportion that the Partners bore the cost of such asset.

         B.     CASH DISTRIBUTIONS

         The Partnership expects  to distribute quarterly, or on a  more
current basis if so  determined by the Co-Managing General Partners, amounts to
the  Partners equal to approximately the  difference between revenues allocated
to  the respective Partners  as provided in  this Article VI, and costs
charged to the  Partners as provided in  Article  V. This  provision  shall
not,  however, serve  as  a limitation  on  the right  of  the Co-Managing
General  Partners to  retain, pledge  or use  so  much of  the  revenues or
other assets  of  the Partnership,  including  amounts  required  to eliminate
any  capital  deficit  of the  Partners,  to conduct additional operations of
the Partnership,  to establish reserves for anticipated  expenditures, or to
repay any amounts borrowed by the Partnership to finance the conduct of such
operations.

         C.     ALLOCATIONS AMONG PARTICIPANTS, SPECIAL LIMITED PARTNERS 
                AND CO-MANAGING GENERAL PARTNERS

         All allocations of income, gain, loss and deduction to the
Participants as a  class shall be allocated among  the  Participants  based on
the  ratio  of  their respective  paid  capital  contributions,  including
Assessments. Expenses and other costs  paid from Assessments shall  be charged
only to those Partners  who paid the Assessment.  All allocation  of income,
gain, loss, deduction  to the  Special Limited  Partners, if  any, shall be
allocated among the Special Limited Partners in  such proportions as shall be
established  at the time of their  admission to the  Partnership or  as they
shall later  agree. All allocations of  income, gain, loss, deduction  and all
capital contributions and Assessments  to the Co-Managing General  Partners
will be divided eighty percent (80%) to Benton and twenty percent (20%) to
Energy Partners.

                  ARTICLE VII. ELECTIONS AND TAX ALLOCATIONS

         For purposes  of federal income  taxes, and  appropriate state  or
local income  taxes, the  following allocations shall be made:

         A.      To the extent  permitted by law, and  except as otherwise
provided by this  Article VII, all income,  gain,  losses  and deductions
shall  be  allocated  to  the party  who  has  been  charged  with  the
expenditures or credited with the revenues giving rise to such deductions or
income.

         B.       The basis of  Partnership properties  for purposes  of Code
Section 613A(c)(7)(D)  shall be allocated in the same ratio as Partnership
Costs are allocated.

         C.      Notwithstanding the foregoing,  however, production required
to  be allocated for the  purpose of computing the depletion deduction
(including percentage depletion in  excess of the depletable basis  of the
property) shall be allocated in the ratio in which the related revenues are
shared.

         D.      All  tax credits and tax  credit recapture shall be allocated
in the  ratio in which revenues are shared at the time the expenditure giving
rise to such tax credit arises.

         E.      The Partnership shall  make an election  to deduct intangible
drilling and  development costs on its federal  income tax return in
accordance with the  option granted by the  Code.  No  election shall be made
by the Partnership to be excluded from the application of the provisions of
Subchapter K of the Code.

         F.      In  the event  of the transfer  of an  interest in  the
Partnership, or in  the event  of the distribution of property to  any party
hereto, the Partnership may (but  is not required to) file  an election in
accordance with the applicable  Treasury Regulations to  cause the basis of
the Partnership's assets to be adjusted for federal income tax purposes as
provided by Code Sections 734 and 743.

         G.      Notwithstanding the foregoing provisions of  this Article VII,
if the capital accounts of  all Participants  are  not equal  and if  any
allocation  of loss  or  deduction to  a  Partner would  reduce such
Participant's capital account  balance below zero or would  increase the
negative balance in such Participant's capital  account at a time  when another
Participant  has a positive capital  account balance, as determined at the
close  of the period in respect  of which the loss  or deduction, as  the case
may be,  is to be allocated, such  excess shall  instead be  allocated pro
rata to  Participants having  positive capital  account balances until such
capital account  balances are reduced to zero; provided, however, that in no
event shall there be a reallocation of any  item of  income, gain,  loss or
deduction  allocated among the  Partners pursuant to  this Agreement for prior
years.

         Notwithstanding the foregoing provisions of this Article VII:

                 (1)      The  losses  and deductions  allocated  to  any  
         Partner pursuant to the foregoing provisions of this Article VII shall
         not exceed the  maximum amount of losses and deductions that  can be so
         allocated without causing  such Partner to  have an  Adjusted Capital
         Account Deficit at the end of any fiscal year.  All losses and
         deductions in excess  of the limitation set forth in this clause (1)
         shall be allocated to other Partners.

                 (2)      If there is a net decrease in  partnership minimum
         gain  (within the meaning of  Treasury  Regulation
         Sections 1.704-1T(b)(4)(iv)(a)(2) and 1.704-1T(b)(4)(iv)(c)) during any
         Partnership  fiscal year,  each Partner  shall  be specially
         allocated items  of  Partnership income and gain  for such year (and,
         if necessary, subsequent  years) in an  amount equal to the greater
         of:


                                      9
<PAGE>   10
                          (i)     the  portion  of  such  Partner's  share  of 
                 the net decrease in "partnership minimum gain," determined in
                 accordance with Treasury Regulation Section 
                 1.704-1T(b)(4)(iv)(f), that is allocable to the disposition of
                 Partnership property subject to "nonrecourse liabilities"
                 (within the meaning of Treasury Regulation Section
                 1.704-1T(b)(4)(iv)(k)(3)), determined in accordance with 
                 Treasury Regulation Section 1.704-1(b)(4)(iv)(e), and

                          (ii)    if such  Partner would otherwise have  an
                 Adjusted  Capital Account Deficit  at the end of  such fiscal
                 year, an  amount sufficient  to eliminate such Adjusted
                 Capital Account Deficit.

         The items of  income and gain to  be so specially allocated pursuant
         to  this clause (2) shall be determined in  accordance with Treasury
         Regulation  Section 1.7041T(b)(4)(iv)(e). This clause (2) is intended  
         to  comply  with the minimum  gain chargeback requirement  of Treasury
         Regulation Section 1.704-1T(b)(4)(iv)(e) and shall be interpreted
         consistently therewith.

                 (3)      Notwithstanding  any provision of  this Paragraph G
         to  the contrary (except clause (2)),  if there is a net decrease in
         Partner Minimum Gain attributable  to a "partner nonrecourse debt"
         (within the  meaning of  Treasury Regulation 
         Section 1.704-1T(b)(4)(iv)(k)(4)) during any Partnership fiscal year, 
         each Partner who has a share of the Partner Minimum Gain attributable  
         to such  partner  nonrecourse  debt, determined  in  accordance  with
         Treasury Regulation Section 1.704-1T(b)(4)(iv)(h)(5), shall be 
         specially allocated items of Partnership income and gain for such
         fiscal year (and, if necessary, subsequent years) in an  amount equal 
         to the greater of:


                          (i)     the portion of such Partner's share  of the
                 net decrease  in Partner  Minimum  Gain   attributable  to
                 such  partner  nonrecourse  debt, determined in accordance
                 with Treasury Regulation Section 1.704-1T(b)(4)(iv)(h)(5), 
                 that is allocable to the disposition of Partnership property 
                 subject to such partner nonrecourse debt, determined in 
                 accordance with Treasury  Regulation Section 
                 1.7041T(b)(4)(iv)(h)(4) and

                          (ii)    if such Partner would  otherwise have  an
                 Adjusted  Capital Account Deficit  at the  end of such fiscal
                 year, an  amount sufficient  to eliminate such Adjusted
                 Capital Account Deficit.

         The items of income  and gain to be  so specially allocated pursuant
         to this  clause (3) shall be determined  in accordance  with Treasury
         Regulation Section 1.7041T(b)(4)(iv)(h)(4). This clause (3) is  
         intended to  comply  with  the  minimum  gain  chargeback 
         requirement  of Treasury Regulation Section 1.704-1T(b)(4)(iv)(h)(4)
         and shall be interpreted consistently therewith.
         
                 (4)      Subject to the priority rules of Treasury Regulation
         Section 1.704-1T(b)(4), if any Partner unexpectedly receives any
         adjustment, allocation or distribution described in Treasury
         Regulation   Sections  1.704-1(b)(2)(ii)(d)(5) or
         1.704-1T(b)(2)(ii)(d)(6), items of Partnership income and gain shall 
         be specially



                                      10
<PAGE>   11
         allocated to such Partner in an amount and manner sufficient  to
         eliminate, to  the extent required  by Treasury Regulation  
         Sections 1.704-1 (b) and  1.704-1T, the Adjusted Capital  Account 
         Deficit of  such Partner  as quickly as possible. It is intended that 
         this  clause (4) qualify and be construed as  a  "qualified income 
         offset" within the  meaning of Treasury Regulation 
         Section 1.704-1 (b)(2)(ii)(d).

                 (5)      Subject to the priority rules of Treasury Regulation
         Section 1.704-1T(b)(4), if any Partner has a deficit  capital account
         at the end of  any Partnership fiscal year  which is in excess of  the
         sum of (i) the amount  such Partner is  obligated, pursuant to
         Paragraph D of Article  XVIII of  this  Agreement  or  otherwise,  to
         contribute  to the  Partnership  upon liquidation  of such  Partner's
         Interest, and  (ii) the amount such  Partner is  deemed to be
         obligated to restore  to the  Partnership pursuant  to Treasury 
         Regulation Sections 1.704-1T(b)(4)(iv)(f)  and
         1.704-1T(b)(4)(iv)(h)(5),  such  Partner   shall  be  specially
         allocated items of  Partnership income and gain in  the amount of such
         excess as quickly  as possible.
        
                 (6)      If special allocations  are required under  clauses
         (2), (3), (4)  and/or (5) in any  fiscal year,  such allocations shall
         be made in  the priorities required  by Treasury Regulation
         Sections 1.704-1(b) and 1.704-1T.

                 (7)       "Nonrecourse   deductions"  (within   the  meaning  
         of Treasury  Regulation Section 1.704-1T(b)(4)(iv)(b)) for  any fiscal
         year  or other period shall be  specially allocated to the  Partners 
         in proportion  to  their  Units  in  the  Partnership.   "Partner
         nonrecourse deductions"  (within the  meaning of  Treasury Regulation
         Section 1.704-1T(b)(4)(iv)(h)(3)) for  any fiscal  year  or other 
         period shall  be  specially allocated  to  the  Partner who  bears the
         economic risk of  loss with respect to the partner  nonrecourse debt
         (within the meaning  of Treasury  Regulation  Section
         1.704-1T(b)(4)(iv) (k)  (4))  to   which  such   partner  nonrecourse
         deductions are attributable in accordance with Treasury Regulation
         Section 1.704-1T(b)(4)(iv)(h).
        

                 (8)      The  Partners   acknowledge  that  all
         distributions  of  cash  (including distributions upon  liquidation of
         the Partnership)  are intended  to be  made in  accordance with the
         priorities set forth in Articles V and  VI and that the  Partners'
         capital accounts are intended to reflect the manner  in which such
         distributions are intended to be made.  The allocations set  forth in
         clauses (1)  (last sentence),  (2), (3),  (4), (5)  and (7)  (first
         sentence) (the  "Regulatory Allocations") are intended to  comply with
         certain requirements  of Treasury Regulation Section 1.704-1  (b) and
         1.704-1T(b)(4),  but may  result in  distortions of  the Partner's
         capital accounts in relation to the distributions  that each Partner
         is intended  to receive  from  the  Partnership. Notwithstanding  any
         other provisions  of  this Article  VII (other  than the  Regulatory
         Allocations),  the Regulatory  Allocations shall  be  taken into
         account in allocating other Profits, Losses and items  of income,
         gain, loss and  deduction to the  Partners so that,  to the maximum
         extent  possible, at any  point in  time the Partners' capital
         accounts shall  reflect  the manner  in which  distributions would  be
         made to  the Partners,  if the  Partnership were  liquidated and  the
         proceeds  of  such liquidation  were distributed to the Partners in
         accordance with Articles VI and XVIII.

                    ARTICLE VIII. APPLICATION OF PROCEEDS

         Net Proceeds will be used solely for the conduct of Partnership 
operations.

         In  view of  the  fact that  Partnership  activities will  not
commence until  sales  are closed  and Partnership  operations commence,
Benton  and  Energy Partners  reserve  the  right to  change  the estimated
allocation of  Proceeds,  as  described below,  in  the  best  interest  of
the Partnership.  However,  it  is anticipated that  the Net  Proceeds will  be
applied  by the  Partnership on  the basis  of approximately  the following
percentages:

         ACTIVITY-ASSUMING THE MINIMUM AMOUNT OFFERED IS RAISED     PERCENTAGE
         ------------------------------------------------------     ----------

         Acquisition of Proven Producing Properties                       100% 
         Drilling and Completion of Partnership Wells                     -0-

         ACTIVITY-ASSUMING THE MAXIMUM AMOUNT OFFERED IS RAISED     PERCENTAGE
         ------------------------------------------------------     ----------

         Acquisition of Proven Producing Properties                      24.5% 
         Drilling and Completion of Partnership Wells                    75.5%


                    ARTICLE IX.  FORMATION OF PARTNERSHIP

     In the sole discretion of the Co-Managing General Partners, the
Partnership  may be formed as soon as  the minimum Subscriptions ($250,000)
have been raised. Additional Participants  may be admitted to the Partnership
until the Offering Termination  Date, as extended. From the time  the minimum
Subscriptions have been received and  the Partnership formed until the
Offering Termination Date or  final closing date,  the Partnership will close
at the end  of each month and  admit new Participants and  acquire either a
greater working interest  in the Proven Producing  Properties previously
acquired or  will acquire interest in additional  Proven Producing Properties.

     At the sole discretion of  the Co-Managing General Partners, the
Partnership may continue to have  monthly closing dates  until such time as
the Offering Termination  Date occurs or the  Partnership sales are  closed.
Once the final termination date has occurred  or the Partnership sales have
closed,  then all Participants will share in  all Partnership costs  and
revenues  on a proportionate  basis thereafter. The  Partnership will not
engage in any recompletions, nor will the Partnership drill any wells, until
the final termination date.

           ARTICLE X. TERM AND CONVERSION OF GENERAL PARTNER UNITS

         A.      The term  of the Partnership  will commence on  the date of
execution of  this Agreement, and will continue until  December 31, 2039, and
will terminate at such earlier time  as all of the  interests and properties
acquired  for the  Partnership have  been fully  depleted, disposed  of, sold
or abandoned,  unless sooner terminated as set forth in Article XVI or XVIII of
this Agreement.

     The calendar year  is the Partnership's fiscal  year, subject to change by
Benton and Energy Partners  as permitted by the Code.

         B.      As  soon as  practicable after  the  completion  of the
Partnership's drilling  activity, and subject  to  the  receipt of  the
opinion of  counsel  described below,  the  General Partner  Units  shall be
converted  to Limited  Partner Units.  Such  conversion shall  occur
automatically  upon compliance  with this paragraph B. All other rights and
obligations under this Agreement shall not be affected by such


                                      12
<PAGE>   13
conversion. Prior to any  such conversion, Benton and  Energy Partners shall
obtain an opinion of  tax counsel to the Partnership to the effect that such
conversion would  not result in any materially adverse federal  tax
consequences to the  Partnership or the General  Partners. In order to
accomplish such conversion,  Benton and Energy Partners will  (i) amend this
Agreement  with such changes therein or  amendments thereto as are  deemed
appropriate by Benton and Energy Partners and that do not adversely  affect the
General Partners, (ii) file  an amended Certificate of Limited  Partnership
with the Secretary of State  for the State of California and  (iii) take such
other  actions as  are necessary  or appropriate  to accomplish  conversion of
the General  Partner interests. Notwithstanding  the  foregoing,  Benton  and
Energy  Partners  shall not  be  obligated  to  cause conversion  of the
Partnership or may delay such conversion if Benton and  Energy Partners or
their tax counsel determine that conversion at that time would not be in the
best interests of the General Partners.

                ARTICLE XI.  RIGHTS AND OBLIGATIONS OF BENTON
                             AND ENERGY PARTNERS

         A.      Benton and Energy Partners  shall be the Co-Managing General  
Partners of the Partnership and  as such shall conduct, direct  and exercise  
full control over  all activities of the  Partnership. Generally, Benton shall 
be primarily responsible for all of the  Partnership's oil and gas  activities 
and Energy Partners shall be  primarily responsible  for  all  the Partnership's
administrative activities.  In order  to carry  out the purposes of  the
Partnership as set forth in Article  III of this Agreement, the  Participants

Partners have  the rights and  obligations set  forth below.

         documents or instruments of any  kind which Benton  may deem 
         appropriate  in carrying out the interests of the Partnership, 
         including, but without limitation, deeds,  assignments, leases,   
         subleases,  operating agreements,  farmout   agreements,  unitization  
         agreements,  pooling agreements, sales  contracts, gas sales 
         contracts, transportation contracts, division orders, transfer orders,
         or  other  marketing agreements,  documents  or  instruments  of  any 
         kind  or  character or amendments thereto, which relate to the affairs 
         of the Partnership;

                 (2)      Energy  Partners shall  maintain  complete  and
         accurate  books  of  account for  the Partnership; said books shall be
         kept at the principal office of the  Partnership and shall be open to
         inspection after  reasonable notice and request  by any Partner  or
         his authorized  representative, at his own expense, at any time during
         ordinary business hours;

                 (3)      Within one  hundred  twenty (120)  days  after the
         end of  the  fiscal year,  Energy Partners shall provide each
         Participant and Special Limited Partner on an annual basis,
         commencing at the end  of  the second  full year  of  Partnership
         operations,  an independent  petroleum  engineer's appraisal of the
         status of the properties;

                 (4)      Energy Partners  shall provide each Participant  and
         Special Limited Partner  with an annual report (copies of which,
         together with a  report on oil and gas reserves and a tax  information
         report, shall be furnished to appropriate  state securities
         administrators, as required) within ninety (90) days after the close
         of the Partnership's fiscal year, containing the following
         information:

                 balance  sheet and  statements  of operations, Partners' 
                 equity  and changes in financial  position, prepared  in 
                 accordance  with generally accepted  accounting principles and

                 an independent certified public accountant;

                          (b)     A description of  each Prospect in  which the
                 Partnership  owns an  interest, including  the cost,
                 location,  number  of  acres under  lease  and interest  owned
                 by  the Partnership,  except  that  succeeding reports  will
                 contain  only  material changes  from the preceding report;

                          (c)     A summary  itemization  by type  and/or
                 classification  of the  total  fees, reimbursements  and
                 compensation  paid by  the  Partnership,  or indirectly  on
                 behalf  of the Partnership, to Benton, Energy Partners or
                 their Affiliates during the period; and


                          (d)     A schedule reflecting the total Partnership
                 costs, and where applicable, the costs pertaining  to each
                 Prospect, the  costs paid  by  Benton and  the costs  paid by
                 the Participants and the  Special Limited Partners, the  total
                 Partnership revenues, the  revenues received  or credited to
                 Benton, and the revenues  received or credited  to the
                 Participants and the Special Limited Partners during the
                 period;

                 (5)      Energy Partners  shall  furnish a  report  to each
         Participant and  Special  Limited Partner by March  15 of each year,
         containing such information  as Energy Partners deems necessary for
         the proper presentation of federal income tax returns;

                 (6)      Energy Partners shall maintain,  at the principal
         office of the Partnership,  copies of  the Partnership's federal,
         state and local income  tax returns and  reports for the  six (6) most
         recent years;

                 (7)      Benton  will  purchase,  at  the  expense of  the
         Partnership,  liability  and other insurance to protect the
         Partnership's properties and business;

                 (8)      Benton  and Energy Partners may enter  into any
         agreement for  the borrowing of money from  a  commercial  bank or
         other  lending  institution for  payment  of  expenses  of drilling
         and completion activities on wells  started with Proceeds, the
         acquisition of  Proven Producing Properties and for payment of
         General and Administrative Expenses, including  the purchase and lease
         of  oil and gas  properties  or  equipment,  and  are  authorized  to
         assign any  portion  of,  or  all  of,  the Partnership's properties
         and revenues therefrom for  the purpose of securing any such  borrowed
         money; provided, however,  that such borrowing  shall not  exceed, in
         principal  amount, twenty-five  percent (25%) of the Proceeds  plus
         all paid Assessments; provided, further, that in  no event will the
         lender have the election  to convert its position as  creditor into an
         equity interest in  the Partnership or in Benton, Energy Partners or
         in any of their Affiliates;

                 (9)      Benton and  Energy  Partners may,  in the  sole
         exercise  of  their discretion,  make unsecured  loans and advances to
         the Partnership at  Benton's and Energy Partners'  interest cost and
         may otherwise borrow money  and assign to the  lender Partnership
         properties and  production therefrom as  security; provided, however,
         that the interest  on loans and  advances made by  Benton and Energy
         Partners or their Affiliates  shall not exceed the amounts  which
         would be charged by  unrelated banks (without regard to financial
         abilities or guarantees) on comparable


                                      14
<PAGE>   15
         loans for the same purpose, and no fees, points or other financing 
         charges will be charged to the Partnership by Benton, Energy Partners 
         or their Affiliates;

                 (10)     In the  states where the  Partnership conducts
         activities,  Energy Partners may  file any necessary instruments
         required to qualify  the Partnership to do business in the  particular
         state as a limited partnership, or to cause the limited partnership
         status of the entity to be recognized;

                 (11)     Benton  may cause title  to Partnership property  to
         be held  in the name  of Benton; provided, however,  that if property
         is  held in the name  of Benton, an unrecorded  assignment to the
         Partnership shall be made and maintained in the Partnership's  files;
         provided, further, that any such assignment shall provide  that the
         properties are  being held for the  benefit of the Partnership  and
         are not subject to the debts, obligations or liabilities of Benton or
         its Affiliates;

                 (12)     Benton and  Energy  Partners  may admit
         Participants,  Special Limited  Partners  or substituted Participants
         without the  consent  of other  Participants  or Special  Limited
         Partners; provided, however, that any transferee of a Unit or  a
         Special Limited Partner's interest will receive a right  to share in
         the profits and capital of the  Partnership but will not be a
         substituted Partner without  the prior  written consent  of Benton
         and Energy  Partners, which  consent  may be  given or withheld in
         their sole and  absolute discretion; provided,  further, that Benton
         and  Energy Partners will withhold their written  consent in the event
         that  they have reasonably determined in  their sole discretion that
         such substitution  could have an  adverse effect  on the  business
         activities or  the legal or tax status of the Partnership, under
         either state or federal law;

                 (13)     Benton and  Energy  Partners  may  admit  one or
         more  additional  managing  general partners which may  become a
         successor entity to  Benton and  Energy Partners and  take action
         which would have the effect of providing an additional  and/or a
         successor managing general partner, if  the holders of a majority of
         the Units outstanding approve; provided, however, that such  approval
         of the holders of Units shall not be necessary if the additional
         managing general partner proposed  by Benton or  Energy Partners is
         (1) an Affiliate of Benton  or Energy Partners; (2) an entity with
         which Benton or Energy Partners has merged;  or (3) a person or entity
         that has purchased  all or substantially all the assets of Benton or
         Energy Partners;

                 (14)     Benton  and Energy Partners may  call for a  vote of
         the Participants  to be taken on the items set forth in Article XVI;

                 (15)     Energy Partners may  cause the investment of
         Partnership funds in short-term  liquid securities  until  the
         expenditure  of  such  funds  is  necessary  in  connection  with
         Partnership activities;

                 (16)     Energy Partners and Benton may amend the Agreement,
         including amending  the Agreement to alter  the Partnership's form so
         that it becomes a  different type of business entity, for business and
         tax reasons, subject to the provisions of Article XVI;


                 (17)     Energy Partners and  Benton may  do any and  all
         things necessary  or appropriate  in order to accomplish the purpose
         of the Partnership, subject to the provisions of this Agreement;




                                      15
<PAGE>   16
                 (18)     Energy Partners and  Benton may conduct other  oil 
         and gas drilling and  acquisition programs or income programs which may
         commence prior to, during or subsequent to the Partnership;

                 (19)     Benton may purchase assets  from the Partnership in
         connection with  a dissolution of the Partnership, at a price which is
         the greater of the then fair market value (which term shall  mean the
         value  of the assets as determined by an independent oil an gas
         engineer) or the highest bona fide offer for such assets by a third
         party, if any, regardless  of any difference between such fair market
         value and the  original cost to the Partnership of such assets
         (subject to the approval of a majority in  interest of the
         Participants if  the asset represents  five percent (5%)  or more  of
         the initial value of the assets of the Partnership);

                 (20)     Energy Partners may  make any and  all elections  for
         purposes of  federal, state  or local income taxes that it deems
         appropriate; and

                 (21)     Benton  and   Energy  Partners  may  submit  a
         partnership  claim  or  liability  to arbitration  or  reference,
         assign  the Partnership  property  and  trust  for  creditors or  on
         the assignee's promise to pay the debts  of the partnership, confess a
         judgment or dispose of the goodwill of the Partnership for adequate
         consideration.

         B.      Benton  and  Energy  Partners  shall  have no  authority  on
behalf  of the  Partnership  or themselves to:

                 (1)      Do any act in contravention of this Agreement;

                 (2)      Use Partnership property  or commingle any
         Partnership  bank accounts or monies  with funds of Benton,  Energy
         Partners or their Affiliates, or to  make advances to Benton, Energy
         Partners or their Affiliates, except where necessary to secure tax
         benefits of  prepaid drilling and completion costs, and  in no event
         will such  advances include  non-refundable payments  for capital
         completion costs prior to the time that a decision is made that the
         well warrants such equipment;

                 (3)      Take  any action  with  respect to  Partnership
         assets or  property  which does  not primarily  benefit the
         Partnership, including,  among other  things, the  utilization of
         Partnership funds as compensating balances for its own benefit, and
         the commitment of future production  if not in the best interests of
         the Partnership;


                 (4)      Make any loans of Partnership funds to Benton, Energy
         Partners or their Affiliates;

                 (5)      Make or institute  any marketing  arrangements or
         other  relationships affecting  the property of the  Partnership where
         the benefits are not fairly  and equitably apportioned according to
         the respective interests of all parties; or

                 (6)      Knowingly enter into any arrangements involving
         working interests in any  oil and gas property which commit the
         working interest to  be held in an entity which limits the  liability
         of the General Partners as to the working interest so as to cause the
         working interest to




                                      16
<PAGE>   17
         be  considered a passive activity  so that losses  from the  working 
         interest may only  offset passive activity income as set forth in Code 
         Section 469.


         C.      The following prohibitions and restrictions shall be
applicable to Benton:

                 (1)      If  Benton sells,  transfers  or  conveys  all or
         any  portion  of  a lease  to  the Partnership, Benton must,  at the
         same  time, sell, transfer,  or convey to  the Partnership an  equal
         proportionate interest in all its other leases in the same Prospects.

                 (2)      A sale, transfer, or conveyance to the  Partnership
         of less than all of the ownership of Benton or its  Affiliates in any
         portion  of a lease (the "Subject Portion") is prohibited  unless the
         interest retained by Benton or  its Affiliates is a working  interest,
         the respective obligations of Benton  or its Affiliates and the
         Partnership to pay costs  with respect to the Subject Portion are
         proportionate  to  their  respective  working  interests  after  the
         transfer, and  Benton's  or  its Affiliates' interest in the revenues
         does not exceed any amount proportionate to its  retained working
         interest.  Benton or  its Affiliates  may not retain  any overrides
         or other  burdens on  the Subject Portion,  and may  not enter  into
         any  farmout arrangements  with respect  to its  retained interest,
         except  to nonaffiliated third parties or other partnerships
         sponsored by Benton. For the purposes of this  paragraph, the  term
         Affiliate   shall not  include another partnership  where the
         interest of Benton is identical to, or less than, Benton's interest in
         the Partnership.

                 (3)      Benton may never profit by drilling  in contravention
         of its fiduciary obligation  to the Partners. All services  provided
         to the Partnership by  Benton or its Affiliates will  be embodied in a
         written contract  which precisely describes the services  to be
         rendered and all  compensation to be paid.

           ARTICLE XII. COMPENSATION OF BENTON AND ENERGY PARTNERS

         Benton  maintains  a  staff  of geologists,  engineers  and  land
personnel  who  are  responsible for screening and acquisition of leases and
for conducting drilling and producing  operations. The costs  incurred in
maintaining these departments, including salaries  of personnel, are allocable
in part to the Partnership's activities and are  included in Partnership Costs.
Such costs shall be paid  or reimbursed by the  Partnership out of Proceeds or
revenues.

     Benton and Energy  Partners will  also be reimbursed for  General and
Administrative Expenses  incurred on behalf of the Partnership  as a fee for
the first twelve (12) months of  Partnership operations and thereafter as a
reimbursement  of expenses incurred.  The amount  of the fee which  will be
allocated to  the Participants for the  first twelve (12) months  of
Partnership operations  will be three percent  (3%) of the  Participants'
Subscriptions.

     MHM Energy Investments, Inc.  shall receive a  wholesaling fee  equal to
three percent  (3%) of the  total Units sold by the broker/dealers for which
MHM Energy Investments, Inc. acts as a wholesaling broker/dealer.

     As set forth  in Article VI, Benton and  Energy Partners will share in
Partnership revenues  in an amount in  excess  of their  contribution to
Partnership costs.  The Participants  and the  Special Limited  Partners
consent to the receipt by Benton, Energy Partners  and their Affiliates of the
benefits and  profits set forth in this Article.

                   ARTICLE XIII. PROTECTION OF THE PARTIES

     In any threatened, pending or completed action, suit or proceeding to 
which the  either of the Co-Managing General Partners  was or is a party  or is 
threatened to be made a  party by reason  of the fact  that it  was or is  a 
Co-Managing General  Partner of the Partnership (other  than an  action by  or 
in  the right  of the Partnership) involving  any alleged  cause of  action for 
damages  arising  from  the performance  of  oil  and  gas  activities,  
including  exploration, development, completion,  operation, or other 
activities  relative to management and  disposition of  oil and gas properties 
or production from such properties,  the Partnership will indemnify  the 
Co-Managing General Partners against expenses,  including  attorneys'  fees, 
judgments  and  amounts  paid in settlement  actually  and  reasonably incurred
by them in  connection with such  action, suit or  proceeding if they  acted in
good faith  and in a manner  they  reasonably believed  to be  in or  not  
opposed  to the  best interests  of the  Partnership, and provided  that  their
conduct  does  not constitute  negligence,  misconduct or  a  breach of  their 
fiduciary obligations to the  Participants and  the Special  Limited Partners. 
The termination  of any  action, suit  or proceeding  by judgment, order or
settlement shall  not, of itself, create a presumption  that Benton or Energy
Partners did not act in  good faith and in a manner which they  reasonably
believed to be in  or not opposed to the best interests of the Partnership.

     In  any  threatened,  pending or  completed  action  or  suit by  the
Partnership  in  the  right  of the Partnership, to  which a Co-Managing
General  Partner was or is  a party or  is threatened to be  made a party,
involving an alleged  cause of action by a Participant or  a Special Limited
Partner for  damages arising from the  activities of a Co-Managing  General
Partner in  the performance of management  of the internal affairs of the
Partnership  as  prescribed by  this Agreement,  the Partnership  will
indemnify  the Co-Managing  General Partner against  expenses, including
attorneys' fees,  actually and reasonably  incurred by  it in connection with
the defense or settlement of such  action or suit if it acted in  good faith
and in a manner it reasonably believed to be in  or not opposed to  the best
interests of  the Partnership, as specified in this  paragraph, except  that no
indemnification  shall be  made in  respect  of any  claim,  issue or  matter
as to  which a Co-Managing General  Partner shall have been  adjudged to be
liable for  negligence, misconduct or  breach of fiduciary obligation in the
performance of its duty to the  Partnership unless and only to the extent that
the court  in  which such  action  or  suit  was  brought shall  determine
upon  application,  that,  despite the adjudication of  liability, but in  view
of all  circumstances of the  case, a  Co-Managing General  Partner is fairly
and reasonably entitled to indemnity for such expenses which the court shall
deem proper.

     To  the extent  that a  Co-Managing General  Partner has  been successful
on the  merits or  otherwise in defense of  any action,  suit or proceeding
referred to above,  or in defense  of any claim, issue  or matter therein,  the
Partnership  shall  indemnify  a  Co-Managing General  Partner  against  the
expenses,  including attorneys' fees, actually  and reasonably incurred by it
in  connection therewith. Any such indemnification  of a Co-Managing General
Partner shall  be prohibited unless  the Co-Managing General  Partner has
determined  in good faith  that the course  of conduct which  caused the  loss
or  liability was in  the best interest  of the Partnership;  that such
liability or  loss was  not the  result of negligence  or misconduct  by a
Co-Managing General Partner; and  that indemnification  of a  Co-Managing
General  Partner or  its Affiliates  will not  be allowed for  any liability
imposed by  judgment, and costs  associated therewith,  including attorneys'
fees, arising from  or out of violation  of state or federal  securities laws
associated with the offer  and sale of Partnership Units. Indemnification will
be  allowed for settlements and related expenses of a lawsuit  alleging
securities law violations,  and for expenses incurred in  successfully
defending such lawsuits, provided that a court either:  (a) approves  the
settlement  and  finds  indemnification of  the settlement  and related  costs
should be made or (b) approves indemnification of litigation costs if a
successful defense is made.

     Any indemnification, unless ordered  by a court, shall be  made by the
Partnership  only as authorized  in the specific case and only upon a
determination by independent legal counsel in a written


                                      18
<PAGE>   19
opinion  that  indemnification of  a  Co-Managing  General Partner  is proper
in  the circumstances  because a Co-Managing General Partner has met the
applicable standard of conduct set forth above.

         The indemnification of a  Co-Managing General Partner shall be limited
to and  recoverable only out of the  assets of the Partnership  and not against
any Limited Partner or  General Partner and indemnification of the Co-Managing
General Partners  as to a third party is only with  respect to such loss,
liability  or damage not otherwise compensated for by insurance carried for the
benefit of the Partnership.

         The Partnership  may not  incur the  cost of  that portion of
insurance which  insures a  Co-Managing General Partners  from any  liability
as  to which the  Co-Managing General  Partner is  prohibited from  being
indemnified under this Article.

     The General Partners hereby  agree that each shall be solely  and
individually responsible only for their pro rata  share  of the  liabilities
and  obligations  of the  Partnership,  and  any Participant  who  incurs
liability in excess of his  pro rata share shall be entitled to  contribution
from the other General Partners.  Pursuant thereto, each Co-Managing  General
Partner further agrees to  indemnify each Participant from  paying any
liabilities or  obligations of  the Partnership  in  excess of  such
Participant's  capital contribution.  Furthermore, although the  General
Partners  may be personally  liable for the  liabilities and obligations  of
the  Partnership, all  such liabilities  and obligations  shall be  paid or
discharged first  with Partnership assets (including insurance proceeds) before
the General Partners  shall be obligated to pay or  discharge any liability or
obligation with their personal assets.

                         ARTICLE XIV. RELATED PARTIES

     Benton  and Energy  Partners  and their  Affiliates or  related  persons
or  entities  may be  engaged or employed by the Partnership to render or
perform  services for the Partnership and/or may  sell property of any kind  or
description  to  it,  or  may  otherwise  engage in  transactions  with  the
Partnership. All  such engagements,  employments and other  transactions shall
not be invalidated by  reason of any such relationships so long as such  person
is engaged, independently of  the Partnership and as an ongoing business  in
rendering such services or selling such equipment and supplies to  a
substantial extent to other persons  and such prices and  terms are not higher
than those normally  charged in the same geographic  area by unaffiliated
persons or companies dealing at arm's length. If the person is not engaged in
business as  provided above, then the price of such  services shall be the cost
of such services, equipment or supplies  to such person or the competitive rate
in the geographical  area, whichever is less. Benton  and Energy Partners may
be presently conducting  or may  conduct in  the future  other oil  and gas
income, drilling and  acquisition programs  which may commence during or
subsequent to this  Partnership. All contracts  entered into between the
Partnership, Benton,  Energy Partners and their Affiliates or  related persons
or entities  shall be terminated without penalty on  not less than thirty  (30)
days' written  notice by the  Partnership or on sixty (60)  days' written
notice  by Benton, Energy Partners or their Affiliates.

     The  leases transferred  to the  Partnership by  Benton or  its Affiliates
shall be  sold at  Cost unless Benton believes  that the appraised value  is
substantially lower than Cost. In  such a case the  value of the lease will be
determined by an independent appraiser and sold at the lower of Cost or
appraised value.

                 ARTICLE XV. RESTRICTIONS ON TRANSFERABILITY

     No Participant or Special Limited  Partner shall have the  power to sell,
assign or transfer  his interest in  the Partnership or to cause a transferee
to become a substituted Partner  except upon the written consent of  Benton
and Energy  Partners. Each  Participant  and Special  Limited Partner
specifically  agrees to  the admission of any  substituted Partner as a Partner
when consented to by Benton and  Energy Partners. Benton and Energy Partners
shall  review any  proposed  transfer and  shall withhold  their consent  in
the event  they determine, in their sole and absolute discretion, that such
substitution could have an


                                      19
<PAGE>   20
adverse  effect on the  business activities  or the  legal or  tax status of
the Partnership or  the remaining partners under either state or federal law.

         Each  of Benton and Energy Partners may sell, assign,  transfer,
pledge or encumber all or any portion of  its  rights  to receive  revenues  as
a  Co-Managing  General Partner  under  this  Partnership Agreement; provided,
however,  that  the assignment  of  such  revenue interest  shall  not  affect
Benton's  and Energy Partners' other rights and obligations pursuant to this
Agreement.

         In addition  to the restrictions  upon substitution of  an additional
Participant or Special  Limited Partner,  neither a Participant  nor a  Special
Limited Partner may  sell his rights to  profits and capital in the Partnership
without  furnishing Benton and Energy Partners  with a copy of the  offer to
buy such interest and giving Benton and Energy Partners the prior  right for a
period of ten (10)  days after receipt of  written notice,  to purchase  such
interest  on the  terms contained  in  such offer.  In the  event Benton  and
Energy Partners do not exercise their prior right to purchase such interest in
profits and  capital within a ten (10) day  period or  notify the Participant
or  Special Limited Partner that  such right will not  be exercised, the
Participant or Special Limited Partner shall have the right to sell his
interest in profits and capital for  a period of  forty-five (45) days.
Thereafter,  the Participant or  Special Limited  Partner shall not  sell any
part  of his interest in profits and capital  without again offering the same
to Benton and Energy Partners. A transferee  of a Partner's right  to profits
and capital  who is not  admitted as a Partner  is not entitled to any of the
rights  of a Partner. A transferee  Participant or Special Limited Partner  has
no greater right to terminate the Partnership than his transferor.

         In no event shall any  assignee or transferee hold less than  one Unit
except by gift or  operation of law.

         ARTICLE XVI. RIGHTS, AUTHORITY AND LIABILITIES
         OF PARTICIPANTS AND SPECIAL LIMITED PARTNERS

         A.      RIGHTS

         By  a majority vote of the outstanding Units,  the Participants (but
not the Special Limited Partners) shall have the right to:

                 (1)      Remove  Benton, Energy Partners  and/or any successor
         Co-Managing  General Partner; terminate all contracts between  the
         Partnership and Benton, Energy Partners and their Affiliates; allow
         Benton, Energy Partners or their Affiliates to remove all of  their
         property interests in the Partnership; and select a substitute
         managing  general partner or additional general  partner to continue
         the  business of the Partnership;

                 (2)      Amend  the Agreement, subject  to the written
         consent of Benton  and Energy Partners concerning matter affecting
         their interests in profits, losses, credits and property;

                 (3)      Terminate the Partnership;


                 (4)      Approve the sale or exchange of all or substantially
         all of the assets; and/or

                 (5)      Approve the admission of an additional  general
         partner proposed to be admitted as  a Co-Managing General Partner  by
         Benton and Energy Partners, subject to  the right of Benton and Energy
         Partners to  admit certain parties  as general  partners without the
         consent of the  Participants, as provided in paragraph 13 of Article
         XI.



                                      20
<PAGE>   21
         Either the  Participants, upon the written request  of ten percent
(10%) of  the outstanding Units, or Benton  or Energy Partners can  cause a
vote to be taken with respect  to the matters referred to above. Notice of a
meeting  of the Participants will  be mailed to the  Participants within ten
(10) days of the  receipt of such written notice unless compliance with federal
or state laws or  regulations requires additional time.  A meeting will  be
held within  sixty (60)  days of the  mailing of  the notice.  The presence,
in person or  by proxy, of the  holders of a majority of  the Units outstanding
shall constitute  a quorum and Participants may vote in  person or by  proxy at
any such meeting. If  a quorum  shall not  be present or  represented at  any
meeting,  a majority of the holders  of Units entitled to  vote at the
meeting, who are present  in person or represented by proxy,  may adjourn the
meeting from time to  time, without notice  other than  announcement at the
meeting,  until a quorum shall  be present or represented.  At any reconvening
of  an adjourned meeting  at which  a quorum  shall  be present  or
represented, any  business  may be  transacted  which  could have  been
transacted at  the original  meeting  if  a quorum  had been  present  or
represented.  No matters  that  would constitute  taking part in control of the
Partnership by the Participants shall be  considered at any meeting.  In order
to facilitate the above rights, each Participant shall have a right  to receive
by mail the complete list of names, addresses and interests of all other
Participants, upon written request to Energy Partners.

         Any action  that may be taken  at a meeting of  the Participants may
be  taken without a meeting  if a consent in writing setting  forth the  action
so  taken is  signed by Participants  owning not  less than  the minimum Units
that would  be necessary  to authorize  or  take such  action at  a  meeting at
which all  the Participants were  present and voted. Prompt notice  of the
taking of action without a  meeting shall be given to the Participants who have
not consented in writing.

         Benton and  Energy Partners shall have the  right to amend the
Agreement;  provided, however, that the Agreement shall  not be amended  by
Benton  and Energy Partners in  any material respect  which would adversely
affect the  rights of  the Participants  except by the  affirmative vote  of
not less than  a majority  of the outstanding amount of Units.

         In  the event that  the Participants vote  to remove  Benton or Energy
Partners and substitute  a new Co-Managing General  Partner  pursuant  to
paragraph  A  of  this  Article  XVI,  the Partnership  or  the  new
Co-Managing General Partner  shall purchase the entire interest of  Benton or
Energy Partners, including  their interest in capital and  revenues on an
assumed dissolution  basis, at a price  determined by mutual  agreement or by
independent appraisal by a petroleum engineer selected  by mutual agreement.
Such purchase  shall provide for payment in  full, or  assignment to Benton  or
Energy  Partners of  a direct  interest in each  Partnership asset and/or
liability equal to  their then interest in  revenue and capital as determined
above.  Such payment or assignment shall occur at  the time of amendment of
the Agreement and substitution of  the new Co-Managing General Partner.

         B.     AUTHORITY

         No Participant  or Special Limited Partner other  than a Co-Managing
General Partner  has the power to manage or  conduct Partnership business, to
act  in the ordinary course of business for  the Partnership or to sign for  or
to bind the  Partnership or any of  its Partners and  no such actions will  be
considered to have been authorized by the other Partners.

         C.     LIABILITY

         No Limited Partner shall be  personally liable for any of the  debts
of the Partnership or any  of the losses thereof;  provided, however, that the
amount committed by  him to  the capital of the  Partnership, any return
thereof, and his  interest in the  Partnership's undistributed  profits shall
be  subject to liability.  Additionally,   a  Limited  Partner  may  be  liable
for  wrongfully  distributed  profits  and  interest  on distributions in
return of capital.


                                      21
<PAGE>   22
         If a Limited  Partner receives the return  of any part of  his
contribution without violation  of this Agreement  or the  California  Revised
Limited  Partnership Act,  he  shall be  liable  to the  Partnership as
provided  by such  Act for  the return of the  amount of  the returned
contributions but  only to  the extent necessary to  discharge the
Partnership's liabilities  to creditors  who extended credit  to the
Partnership during the period the contribution was held by the Partnership.

         D.      MISCELLANEOUS

         No  Participant or  Special Limited Partner  has any  right of
repayment  of his  contributions to the Partnership  except as  expressly
provided in  this Agreement.  Participants  have no  right  to vote  on any
Partnership matters  except as set forth  in this Agreement.  Special Limited
Partners have no  voting rights except as provided by law. The Participants
and Special Limited Partners agree  that they will not request  a decree  of
dissolution from  a court  until  a  majority vote  of the  outstanding  Units
of  Participants has approved such decree.

            ARTICLE XVII. WITHDRAWAL OF BENTON OR ENERGY PARTNERS

         A.      EVENTS REQUIRING CONSENT OF ALL PARTNERS TO AVOID 
                 WITHDRAWAL

         Except as waived in writing by all Partners at the time, Benton,
Energy Partners  or any other General Partner shall  cease to be  a General
Partner of  the Partnership upon  the happening of  any of the following events
of withdrawal: (1) Benton, Energy  Partners or a General  Partner withdrawing
from  the Partnership by giving one hundred  twenty (120) days written notice
to  the other Partners, provided  that the Partnership has completed  its
primary drilling and  completion activities and provided  that the  withdrawing
Partner pays all expenses incurred as a result of  its withdrawal; (2) Benton,
Energy Partners or  a General Partner is removed as a  General Partner in
accordance with the terms of the Agreement; (3) in  the case of a General
Partner who is a  natural person, the death  or adjudication or  incompetency
of a General  Partner; (4) in  the case of a General Partner who is acting  as
a General Partner by virtue of being  a trustee of a trust, the  termination of
the trust, but not merely the substitution of a new trustee; (5) in the  case
of a General Partner which is a separate partnership, the dissolution and
commencement of winding up of the partnership; (6) in the case  of Benton,
Energy Partners or a General Partner that is a corporation, the  dissolution of
the corporation or the revocation of its charter; (7) in  the case of an
estate, the distribution by  the fiduciary of the  estate's entire interest in
the Partnership; or  (8) in the case of a  General Partner that is any  other
legal entity, the cessation of the legal existence of the legal entity.

         Upon withdrawal,  a General Partner other  than Benton or Energy
Partners shall retain all  rights to its proportionate  share of revenues  and
capital, but  shall cease to  have any vote or  engage in any  other activities
as a General Partner. The withdrawing  General Partner will have the right to
transfer his interest subject to provisions of Article XV hereof.

         B.      EVENTS NOT CAUSING WITHDRAWAL

         Neither Benton, Energy Partners nor any other  General Partner shall
cease to be a general  partner of the  Partnership upon the happening of  any
of the following events: (1) Benton,  Energy Partners or a General Partner
makes an assignment  for the benefit of  creditors; (2) Benton,  Energy
Partners  or a General Partner files  a voluntary petition  in bankruptcy; (3)
Benton, Energy Partners or  a General Partner  is adjudicated bankrupt  or
insolvent; (4)  Benton, Energy Partners or  a General Partner  files a
petition or answer seeking for itself  any reorganization,  arrangement,
composition,  readjustment, liquidation,  dissolution or  similar relief under
any statute, law or regulation;  (5) Benton, Energy Partners or a  General
Partner files an answer or other pleading admitting or failing to contest the
material allegations of a

                                      22
<PAGE>   23
petition filed against  it in any proceeding of  a type described in clause
(4), above; or (6) Benton, Energy Partners or a General Partner  seeks,
consents to or acquiesces  in the appointment of a  trustee, receiver or
liquidator of Benton,  Energy Partners or  a General Partner  or of all  or any
substantial part of  Benton's, Energy Partners' or a General Partner's
properties.

                          ARTICLE XVIII. DISSOLUTION

         A.      The  parties   specifically  agree  that  the   retirement,
resignation,  expulsion,   death, incompetency, bankruptcy, insolvency,
dissolution, withdrawal, conveyance of the  interest of a Participant  or
Special  Limited Partner,  or admission  of a  new partner,  or express
decision of  a Participant  shall  not dissolve the  Partnership.  In  such
event,  the heir,  legal  representative,  successor or  assign  of  such
Participant or Special Limited Partner, as  the case may be, shall become an
assignee of such Participant's  or Special Limited Partner's interest. Such
assignee shall not have the rights  of a substituted Partner, unless (i)  such
heir,  legal representative,  successor  or assign  shall  execute an  addendum
to this  Agreement, agreeing to be  bound by all of the  terms and conditions
hereof  and to assume all of the obligations  of the deceased  or incapacitated
Participant  or Special Limited  Partner hereunder and  (ii) both  Benton and
Energy Partners  shall have consented to such substitution, which  consent may
be given or withheld in their sole and absolute  discretion. When  a
Participant or  Special Limited  Partner dies  or retires  and the  business is
continued, the  Participant, Special Limited Partner or his  estate has no
right  to require the Partnership or the  remaining Participants  or Special
Limited Partners  to make  an evaluated  purchase  of  his Partnership
interest.

         B.      If,  notwithstanding the intent of the Partners as set forth
in  paragraph A. above, any event listed in  paragraph A. results in the
dissolution  of the Partnership, such dissolution shall be considered in
contravention of the  Agreement, and the Partnership shall  be continued or
reconstituted.  In the event  that the Partnership is  dissolved, despite the
intention  of the Partners, through any acts pursuant  to paragraph A. above,
the Partners agree that Energy  Partners may take any action which  it deems
necessary or appropriate to continue the  Partnership or to reform the
Partnership  on terms as identical as possible to this Agreement.  In  the
event that Energy Partners  causes a continuation or  reformation of the
Partnership, the liability of all Partners will be deemed to continue
uninterrupted.


         C.      The following actions shall cause  a dissolution of the
Partnership, provided that Benton  or Energy  Partners cannot  take any
voluntary  action to cause  dissolution between the time  it receives notice
from the  Participants of  their intent  to remove  a Co-Managing  General
Partner  and the  completion of  the voting and the actions, if any, authorized
by the voting:

                 (1)      The  transfer  or assignment  of the  entire
         interest of  Benton or  Energy Partners unless a remaining Co-Managing
         General Partner agrees to continue the Partnership;


                 (2)      The  written  vote  or  consent  by  Participants
         representing  a  majority  of  the outstanding Units and as further
         provided by Article XVI;

                 (3)      The conduct of the Partnership becoming unlawful;

                 (4)      The disposition of all or substantially all of the
         assets of the Partnership;

                 (5)      The expiration of the term of the Partnership as
         provided in Article X;



                                      23
<PAGE>   24
                 (6)      An event of withdrawal or  expulsion of Benton and 
         Energy Partners,  unless at the time there is  at least  one other  
         General Partner who  carries on  the business  of the  Partnership; 
         provided, however, that  the Partnership is not  dissolved and is not 
         required to be wound up  by reason of any event of withdrawal if, 
         within ninety (90) days after  the withdrawal, all remaining Partners 
         agree in writing to continue the  business of the Partnership  and to 
         the appointment  of one or more  managing general partners if 
         necessary or desired; or

                 (7)      The entry of a decree of judicial dissolution.


         Any dissolution caused by an event other than those events listed
above as causes of dissolution will be considered a dissolution in
contravention of this Agreement.

         D.      Upon dissolution  and winding  up of  the Partnership, all  of
the assets of  the Partnership may  be liquidated, and all Partnership assets 
shall be applied in the following order:

                 (1)      To  creditors, including  Partners  who are  
         creditors, to the extent  permitted by  law, in satisfaction of 
         liabilities of  the Partnership other than liabilities for  
         distributions to Partners; then

                 (2)      To Partners in proportion to their positive capital
         account balances.

         With respect to the distributions made in liquidation, Partners who
are not  otherwise creditors shall not have  the status of  and be entitled to
the  remedies available to a  creditor of the  Partnership. In the event of  a
distribution of assets in kind, all assets  to be distributed to the
Participants and the Special Limited Partners  shall be distributed to an
independent trustee  who shall hold title for the benefit of such Participants
and Special Limited Partners,  collect and distribute  to such Participants
and Special Limited Partners  all of the  net income from such  properties
and/or sell such properties  as such independent trustee deems to be in the
best interests of, and at  the expense of, the Participants and Special Limited
Partners.  The  independent trustee shall  operate the liquidating trust
arrangement for so long as  is necessary to sell or exchange  Partnership
Assets for  cash on terms which  the trustee deems to  be in the best  interest
of the Participants and Special Limited Partners.

         In the event  the liabilities of  the Partnership exceed its  assets
upon liquidation or  otherwise if any General Partner  then has a negative
balance in  its capital account, the  General Partners must contribute funds
to the Partnership,  within the period required  by Treasury Regulation
Section 1.704-1, in the ratio of their negative capital accounts until negative
capital accounts  are eliminated. In  the event any  General Partner fails  to
make  the required contribution,  Benton agrees to  pay the amounts  required,
and no  Participant or Special Limited Partner shall have any liability for the
amounts not contributed by other Participants.

         Upon termination of the Partnership, a statement shall be prepared by
the certified public  accountant employed by the Partnership  setting forth the
assets and liabilities  of the Partnership and the distribution of cash  or
property of the Partnership as prescribed above,  and a copy of such  statement
shall be furnished to each Partner within ninety (90) days after completion of
winding up of Partnership business.

         For  purposes of the  liquidation of  Partnership assets,  the
discharge of  its liabilities,  and the distribution  of the  remaining funds
and/or assets  among the Partners  as above described, in  the event that all
Partnership  property  is not  sold,  or  in  the  sole  discretion of  Benton
cannot  be  sold  so  that distributions in  kind to the Partners  are
appropriate or  necessary, Benton and  Energy Partners shall cause all
Partnership assets  to be appraised by a competent,  qualified appraiser. Any
excess  of fair market value, as evidenced by such appraisal, over book value
of any Partnership assets and any excess of book value


                                      24
<PAGE>   25
over such fair market  value of any Partnership assets shall be  deemed gains
or losses of the Partnership, as the case may  be, and subject to the
provisions of  Articles V and VI,  above, Benton and Energy Partners shall have
the  authority on behalf  of the  Partnership to sell, convey,  exchange, buy
back,  or otherwise transfer the  assets of the  Partnership upon  such terms
and  conditions as  it determines  appropriate subject  to the terms of this
Agreement. A reasonable time shall be allowed for  the orderly liquidation of
the assets of  the Partnership  to minimize  normal losses  of the  liquidation
period. Any  return of all  or any  portion of the contributions by a Partner
to the capital of the Partnership shall be made solely from  or out of
Partnership assets and Benton and Energy Partners shall not be personally
liable for any such return.

                   ARTICLE XIX. ASSESSMENTS AND BORROWINGS

         The Participant  are  subject  to the  payment  of  one  or more
Assessments  as  additional  capital contributions  to the  Partnership.  No
Assessment  shall  be made,  however,  unless  and  until all  original
Proceeds  have been expended or committed The failure  of one or more
Participants  to pay any Assessment does not  result in  personal liability,
but will  result in  the dilution  of such  Participants' interest  in all
Partnership revenues and costs.  A Participant's interest in the  Participants'
share of Partnership  revenues is based  on the ratio that  the sum of his
Subscription  and paid Assessments bears  to the total sum  of all
Participants' Subscriptions and Assessments  paid by all Participants
(including  Benton and Energy Partners to the extent they pay  non-consenting
Participants' shares of Assessments). The  failure of a Participant to pay his
share of  an Assessment will  reduce this ratio  accordingly, as of  the
closing of the pre-Assessment  or Assessment period.  If one or  more
Participants  fail to pay such  Assessment, Benton and  Energy Partners may
contribute  the  nonconsenting  Participants'  shares  of  such  Assessment,
at  their  election,  which  will proportionately increase the interest  of
Benton and Energy Partners  in all Partnership revenues and costs, on the same
basis as if Benton and Energy Partners  were a Participant. If the Participants
fail to pay an amount equal to at  least fifty percent (50%) of  the total
Assessment requested, Benton or Energy  Partners have the option  of  either
returning  to  the  Participants   all  Assessments  contributed,   or
contributing  the non-consenting Participants' shares of such  Assessment. If
the amount contributed by the Participants  equals or exceeds fifty percent
(50%) of  the Assessment requested, Benton or Energy Partners may contribute
all or  a portion  of the non-consenting Participants'  shares of  such
Assessment and also  may reduce the Partnership's participation in  the
Prospect for  which the Assessment  was made by  entering into  a farmout
agreement with respect to such Prospect.

         The cumulative  amount of Assessments shall  not exceed twenty-five
percent (25%) of the  Proceeds of the Partnership.

         After  the Partnership has expended or  committed its Proceeds for
property acquisitions and drilling operations,  Benton   and  Energy  Partners
may  finance  necessary  additional   operations  by  Partnership Assessments,
use of  Partnership revenues,  or borrowings.  Assessments may  be levied  by
Benton  and  Energy Partners  only for  the purpose  of conducting  subsequent
operations  on Prospects  upon which  evaluation had begun during  the
Partnership's initial operation  or on leases  sufficiently related to  such
Prospects as to merit, in Benton's  and Energy Partners' judgment,  additional
operations to fully  develop those  Prospects or to acquire additional
undeveloped  leases located on the geological feature or features of  Prospects
owned by the Partnership in order to fully develop and protect its Prospects.

         Benton  and Energy Partners will give written notice to  each
Participant of the nature and purpose of any  Assessment,  the  Participant's
proportionate  share of  the  estimated  costs,  and  the effect  of  the
Participant's not participating in  the Assessment. A Participant may  elect to
participate in an Assessment by notifying  Benton and Energy  Partners of his
intention to participate and  sending the requested  payment by mail within
twenty (20) days  after Benton and Energy Partners mail  the written Assessment
notice, unless such period  is extended  by  Benton and  Energy  Partners. Any
Participant  shall be  deemed  to  have refused  to participate  in any
Assessment by  notifying Benton and  Energy Partners of his  election not to
participate or by failure to pay his share of the Assessment when due. In the
event that the


                                      25
<PAGE>   26
proportionate interests of the Partners  change by reason of Assessments,
solely for the purpose of  allocating costs and  revenues, there shall be  an
interim closing  of the  Partnership financial books  immediately upon closing
of the Assessment period, with  all allocations made as of  the date of the
interim closing according to the  interests of  the Partners  immediately prior
to payment  of the  Assessments. The  pre-Assessment or Assessment period
closes on the  last day  established by  Benton and  Energy Partners for  the
payment of  an Assessment by the Participants.

         Benton  intends  to  develop  the Partnership's  Prospects  fully
through  the  initial Proceeds  and Assessments.  However, no  assurance can be
made that  such funds  will be  sufficient. If such  funds are not sufficient,
the Partnership  may borrow the necessary  funds, may farm out  the undeveloped
portion of certain Prospects, or may sell or abandon certain undeveloped
leases.

                        ARTICLE XX. POWER OF ATTORNEY

         The  Participants and the  Special Limited  Partners constitute  and
appoint  Energy Partners  and its successors  and assigns,  with  full  power

acting in such capacities except when the amendment is made pursuant to Article
XVI.

drilling of a well when total depth has been reached,  appropriate tests have
been made  and a decision must be made to run  and set production casing or
production liner,  as the case may be, and a decision  to commence attempting
to complete the  well is made or the well is plugged and abandoned.

         Code. The Internal Revenue Code of 1986, as amended.

         Completion Costs.   "Completion Costs" means, as to any well all
those costs incurred  after Casing Point. Generally,  these costs include  all
costs, liabilities  and expenses, whether  tangible or intangible, necessary

Partners' or their Affiliates' lease inventory, to the extent such
evaluations condemn the acreage  prior to selection for  the Partnership. Delay
rentals, ad  valorem taxes, interest on funds used  to acquire or maintain
properties and direct expenses will not  be included in  cost when  such
expenses were incurred by  Benton, Energy Partners or their Affiliates in
connection with the past drilling  of wells which are not producers of
sufficient quantities of oil  or gas to make commercially  reasonable their
continued operation,  or when such expenses, as  enumerated in subsections (3)
and (4)  hereof, were  incurred more  than thirty-six (36)  months prior to

providing such services, determined in  accordance  with  generally  accepted
and  customary  industry  practices. Except  as  otherwise indicated or  as
the context  requires,  cost   means  the  price paid  by Benton,  Energy
Partners or  their Affiliates in a fair or arm's length transaction.

         Development Well.  A  well drilled as  an additional well  to the

                     ARTICLE IV.  CAPITAL OF THE PARTNERS

         A.   CAPITAL CONTRIBUTIONS

              1.  Each Participant  has made  a capital contribution to  the
         Partnership in cash  equal to the amount set forth in  the
         Subscription Agreement submitted to  Energy Partners by the
         Participants and accepted by Energy Partners.  A Participant's
         interest in the Partnership, including his interest  in undistributed
         profits, will be subject to the debts of the Partnership.

              2.  Benton and Energy Partners will make a capital contribution
         to the Partnership as required to pay their share of costs as provided
         in Article V hereof, and in return for such payments, Benton, Energy
         Partners and other General Partners shall be entitled to share in all
         items of income, gain, loss, deduction or credit allocated to the
         respective Partners as provided in Article VI.

              3.  Benton and  Energy Partners  will make a  capital
         contribution  of one percent  (1%) of the total contributions as a
         General Partner.

              4.  Each  Participant is  subject to Assessments  in the  amount
         of  up to  twenty-five percent (25%) of the amount of his original
         capital contribution.

              5.  The Special  Limited Partners  shall not  be liable  for
         Assessments  or to  make any  other capital contributions to the
         Partnership.



                                      6

         B.    DETERMINATION OF CAPITAL ACCOUNTS

         A single capital  account shall  be maintained for  each Partner
(or transferee of  a Partner,  which transferee  shall succeed  to the
allocable  portion of  the capital  account  of his  transferor, as  of  the
effective  date of  the transfer).  The capital  account  for  each Partner
will be-  determined based  on the Treasury Regulations  regarding  maintenance
of  capital  accounts  promulgated  under  Code  Section  704(b), including
Treasury  Regulation  Section 1.704-1(b)(2)(iv)(g).  Generally,  these  Treasury
Regulations  provide  that capital  accounts of Partners shall be increased  by
(1) the amount  of money contributed by  a Partner to the Partnership, (2)  the
fair  market value  of, property  contributed by  a Partner  to the
Partnership and  (3) allocations to a Partner of Partnership  taxable income
and gain (or items thereof).  Capital accounts will  be decreased by (1) the
amount  of money distributed to a Partner by the  Partnership, (2) the fair
market  value of  property  distributed to  a  Partner by  the Partnership,
(3)  allocations of  Partnership  tax  loss and deduction (or items thereof),
and (4) organizational and syndication costs which are not amortized.

         In the event of  a distribution in kind  of any property, the  capital
accounts of the Partners  shall first be  adjusted  to reflect  the manner  in
which  the  unrealized  income, gain,  or loss  inherent in  the property
(which has not been  previously reflected in capital accounts) would  be
allocated among the Partners if there were a taxable disposition of the
property at its fair market value.

         C.    SIMULATED DEPLETION ACCOUNT

         Solely for purposes of maintaining capital accounts,  depletion with 
respect to oil and gas properties shall be computed at the Partnership
level.  The Partnership shall compute a simulated  depletion allowance on each
oil or  gas  property using  the percentage  depletion  method.  The
Partnership's  simulated  depletion allowance shall  reduce the  Partners'
capital  accounts in  the same  proportion as such  Partners (or  their
predecessors  in interest) were allocated adjusted  basis with respect to such
property.  The aggregate capital account  adjustments for  simulated depletion
allowances with respect  to an  oil or  gas property  shall not exceed  the
Partnership's adjusted tax basis in such property.  Upon the  taxable
disposition of an oil or gas property by the Partnership, the  Partnership's
simulated gain or loss shall  be determined by subtracting its simulated
adjusted basis in such property from the amount realized from such
disposition.  (The Partnership's simulated adjusted basis  in an oil and  gas
property is determined  in the same manner as adjusted  tax basis except  that
simulated depletion  allowances are taken into  account instead of  actual
depletion allowances.) Any resultant  simulated gain shall  be allocated to the
Partners in the  same manner as  that portion of the amount realized  from such
disposition which  exceeds  the Partnership's  simulated  adjusted basis  in
such property is allocated to  such Partners and shall  increase such Partners'
capital  accounts accordingly.  Any resultant simulated  loss shall be
allocated to the Partners  in proportion to the  Partners' allocable shares of
the  total  amount  realized from  the  disposition  of  such  property that
represents recovery of the Partnership's simulated adjusted basis in such
property, and shall reduce such Partners' capital accounts accordingly.

         D.   INTEREST ON CAPITAL

         No interest  shall be paid on the  capital account of, or  on any
capital contributed  by, any Partner either before or after the time repayment
should be made.

                     ARTICLE V. COSTS CHARGED TO PARTNERS


                                      7
<PAGE>   8
         For  purposes of  determining liability  for Assessments,  sharing in
distributions and  otherwise as provided herein, amounts  expended by the
Partnership shall  be charged as follows,  provided that costs  paid out of
Assessments shall only be charged to Partners who paid such Assessments:

         A.   PARTNERSHIP COSTS

         All  Partnership Well  Costs,  including  completion costs,  costs  of
Recompletion Wells,  costs  of acquiring  and developing Proven Producing
Properties, and geological, geophysical  and seismic costs, and all
Organization and Marketing Expenses shall be allocated one hundred percent
(100%) to the Participants.

         B.   OPERATING COSTS

         The expenses of operating  Partnership Wells are  to be charged  in
the same  ratio that revenues  are shared in such wells, pursuant  to paragraph
A of Article Vl. In  addition, operating costs shall include  the costs of
recompleting Partnership Wells.

         C.   OTHER COSTS

         All  General  and  Administrative  Expenses  shall  be  charged
seventy-five percent  (75%)  to  the Participants  and twenty-five percent
(25%) to  the Co-Managing General Partners, except that the reimbursement of
General and Administrative Expenses payable  to the Co-Managing General
Partners for the first twelve (12) months of the Partnership's operations
and equaling  three percent (3%) of the Participants' Subscriptions shall be
charged entirely  to the Participants.   All costs which  are not otherwise
specifically  provided for in this Article  V(A) above, including, but  not
limited to Selling Commissions,  shall be charged one  hundred percent (100%)
to the Participants.

         Costs charged  to  Participants and  the  Co-Managing General
Partners will  be  allocated among  the Participants as provided in paragraph C
of Article VI.

         D.   LOSS ON SALE OF PARTNERSHIP ASSETS

         If the Partnership sells any oil and gas  property at a price which is
less than its  undepleted cost, the Partnership shall  charge the loss on such
sale to the Partners in the ratio of their remaining undepleted bases in such
property at the time of sale.

         If the Partnership sells any  asset, other than an oil and gas
property, at a price which is less than its undepreciated cost, the Partnership
shall charge the  loss on such sale to the Partners  who bore the cost of such
asset.

         ARTICLE VI. ALLOCATION OF REVENUES AND DISTRIBUTIONS OF CASH

         A.   ALLOCATION OF REVENUES

         All  Partnership  revenues shall  be allocated  seventy-four  and
one-fourth  percent (74.25%)  to the Participants,  twenty-four  and
three-fourths percent  (24.75%) to  the Co-Managing  General Partners  and one
percent  (1%) to the Special Limited  Partners.  For Partnership purposes,
revenues  shall mean funds received by the Partnership from all sources, except
capital contributions, borrowings,



                                      8
<PAGE>   9
Assessments  and interest on subscriptions, whether  occurring during the  term
of the Partnership or occurring as part of any plan of  dissolution and
liquidation of the Partnership;  provided, however, that the portion of the
revenues  generated by  the taxable  disposition of  a Partnership  oil and gas
property that  represents recovery of its simulated  adjusted tax basis therein
will be allocated to the Partners in  the same proportion such  Partners (or
their predecessors  in interest) were  allocated the  basis of  such property
pursuant to paragraph C  of Article  IV; provided,  further, that  the portion
of the  revenues generated  by the  taxable disposition of a Partnership
asset, other than an  oil and gas  property, equal to the Partnership's
adjusted tax basis in  such property shall be allocated  to the Partners in the
same proportion that the Partners bore the cost of such asset.

         B.   CASH DISTRIBUTIONS

         The Partnership expects to distribute quarterly,  or on a more current
basis if so determined by  the Co-Managing General Partners, amounts to  the
Partners equal to approximately the difference between  revenues allocated to
the respective Partners as provided  in this Article  Vl, and costs  charged to
the  Partners as provided in  Article V.   This  provision shall not,  however,
serve as  a limitation on  the right of  the Co-Managing  General  Partners
to  retain, pledge  or  use  so  much of  the  revenues  or  other  assets  of
the Partnership,  including  amounts  required to  eliminate  any capital
deficit  of  the  Partners, to  conduct additional operations of the
Partnership, to establish reserves  for anticipated expenditures, or to  repay
any amounts borrowed by the Partnership to finance the conduct of such
operations.

         C.   ALLOCATIONS AMONG PARTICIPANTS, SPECIAL LIMITED PARTNERS AND 
              CO-MANAGING GENERAL PARTNERS

         All allocations of income, gain, loss and deduction to the 
Participants as a class shall be  allocated among  the  Participants  based  on
the  ratio  of  their  respective paid  capital  contributions,  including
Assessments. Expenses  and other costs paid from Assessments  shall be charged
only  to those Partners who paid the Assessment.   All allocation  of income,
gain,  loss, deduction to  the Special Limited  Partners, if  any, shall be
allocated among the Special  Limited Partners in such proportions as shall be
established at the  time of their admission  to the Partnership or as they
shall later  agree.  All allocations of  income, gain, loss, deduction and  all
capital contributions and  Assessments to the Co-Managing  General Partners
will be  divided eighty percent (80%) to Benton and twenty percent (20%) to
Energy Partners.

                 ARTICLE VII.  ELECTIONS AND TAX ALLOCATIONS

         For purposes  of federal  income taxes, and  appropriate state or 
local  income taxes, the  following allocations shall be made:

         A.      To the extent  permitted by law, and except  as otherwise
provided by  this Article VII,  all income,  gain, losses  and  deductions
shall  be  allocated to  the  party  who  has  been  charged  with  the
expenditures or credited with the revenues giving rise to such deductions or
income.

         B.      The  basis  of  Partnership properties  for purposes  of Code
Section 613A(c)(7)(D)  shall be allocated in the same ratio as Partnership
Costs are allocated.

         C.      Notwithstanding  the foregoing, however,  production required
to be  allocated for the purpose of  computing the depletion deduction
(including  percentage depletion in excess of the depletable basis of the
property) shall be allocated in the ratio in which the related revenues are
shared.



                                      9
<PAGE>   10
         D.      All tax credits and  tax credit recapture shall  be allocated
in the  ratio in which revenues are shared at the time the expenditure giving
rise to such tax credit arises.

         E.      The  Partnership shall make an election  to deduct intangible
drilling  and development costs on its  federal Income tax  return in
accordance with the  option granted by the  Code.  No  election shall be made
by the Partnership to be excluded from the application of the provisions of
Subchapter K of the Code.

         F.      In the  event of  the transfer  of an  interest in the
Partnership, or  in the  event of the distribution of property  to any party
hereto, the  Partnership may (but is not required to)  file an election in
accordance with  the applicable Treasury Regulations  to cause the basis of
the Partnership's assets to  be adjusted for federal income tax purposes as
provided by Code Sections 734 and 743.

         G.      Notwithstanding  the foregoing  provisions  of  this Article
VII, any  allocation of  loss or deduction to  a Partner would reduce such
Participant's capital  account balance below zero  or would increase the
negative  balance in such Participant's capital account at a time when  another
Participant has a positive capital account  balance, as determined at the close
of  the period in respect of which the loss or deduction, as the  case may  be,
is to  be allocated,  such excess  shall instead be  allocated pro  rata to
Participants having positive capital account  balances until  such capital
account balances  are reduced to zero;  provided, however, that  in no event
shall  there be  a reallocation  of any  item of  income, gain,  loss or
deduction allocated among the Partners pursuant to this Agreement for prior
years.

         Notwithstanding the foregoing provisions of this Article VII:

                 (1)      The  losses  and  deductions  allocated to  any
         Partner  pursuant  to the  foregoing provisions of this Article  VII
         shall not exceed the maximum amount of  losses and deductions that can
         be so allocated  without causing such Partner to  have an Adjusted
         Capital Account Deficit  at the end of any  fiscal year. All losses
         and deductions in excess of  the limitation set forth  in this clause
         (1) shall be allocated to other Partners.

                 (2)      If there  is a  net decrease  in  partnership
         minimum gain  (within the  meaning of Treasury  Regulation Sections
         1.7041T(b)(4)(iv)(a)(2)  and  1.704-1T(b)(4)(iv)(c)) during  any
         Partnership fiscal year, each  Partner shall be  specifically
         allocated items of  Partnership income and  gain for such year (and,
         if necessary, subsequent years) in an amount equal to the greater of:

                 (i)  the portion of such Partner s share of the net decrease
                 in  partnership minimum gain,  determined  in accordance  with
                 Treasury Regulation Section 1.704-1T(b)(4)(iv)(f), that is
                 allocable  to  the  disposition  of  Partnership property
                 subject  to   nonrecourse  liabilities   (within  the  meaning
                 of Treasury Regulation Section 1.704-1T(b)(4)(iv)(k)(3)),
                 determined in accordance with Treasury Regulation Section
                 1.704-1T(b)(4)(iv)(e), and

                 (ii)   if  such Partner  would  otherwise have  an Adjusted
                 Capital  Account Deficit  at the end of such  fiscal year, an
                 amount  sufficient to eliminate such Adjusted Capital Account
                 Deficit.

         The items  of income  and gain  to be  so specially  allocated
         pursuant  to this  clause (2)  shall be determined in accordance with
         Treasury Regulation Section 1.704-1T(b)(4)(iv)(e). This clause (2) is



                                      10
<PAGE>   11
         intended   to   comply   with  the   minimum   gain  chargeback  
         requirement of Treasury Regulation Section 1.7041T(b)(4)(iv)(e) and
         shall be interpreted consistently therewith.

                 (3)      Notwithstanding any  provision of  this Paragraph  G
         to  the contrary  (except clause (2)), if there is a  net decrease in
         Partner Minimum Gain attributable to  a partner nonrecourse debt
         (within the  meaning of Treasury Regulation Section
         1.704-1T(b)(4)(iv)(k)(4)) during any Partnership fiscal year,  each
         Partner who  has  a  share of  the  Partner  Minimum Gain
         attributable  to  such partner nonrecourse debt,  determined in
         accordance with Treasury Regulation Section 1.704-1T(b)(4)(iv)(h)(5),
         shall be specially allocated items of Partnership income and gain for
         such fiscal year (and, if necessary, subsequent years) in an amount 
         equal to the greater of:

                 (i)   the portion  of such  Partner s share of  the net
                 decrease in Partner Minimum  Gain attributable  to such
                 partner nonrecourse debt,  determined in accordance  with
                 Treasury Regulation Section 1.704-1T(b)(4)(iv)(h)(5), that is
                 allocable to the disposition of Partnership property subject
                 to such partner nonrecourse debt, determined in accordance
                 with Treasury Regulation Section 1.704-1T(b)(4)(iv)(h)(4), and

                 (ii)   if  such Partner  would otherwise  have  an  Adjusted
                 Capital  Account Deficit at  the end of such  fiscal year, an
                 amount sufficient to eliminate such Adjusted Capital Account
                 Deficit.

         The items  of income  and gain  to be so  specially allocated
         pursuant to  this clause  (3) shall  be determined in  accordance with
         Treasury Regulation Section 1.704-1T(b)(4)(iv)(h)(4). This clause (3)
         is intended to  comply with  the minimum  gain chargeback  requirement
         of  Treasury Regulation  Section 1.704-1T(b)(4)(iv)(h)(4) and shall be
         interpreted consistently therewith.

                 (4)      Subject  to  the priority  rules  of Treasury
         Regulation Section 1.704-1T(b)(4), if any Partner unexpectedly receives
         any adjustment,  allocation  or  distribution  described in  Treasury
         Regulation Section 1.704-1(b)(2)(ii)(d)(4), 1.704-1(b)(2)(ii)(d)(5) or
         1.704-1T(b)(2)(ii)(d)(6), items of Partnership income and  gain shall
         be specially allocated  to such  Partner in an  amount and  manner
         sufficient to eliminate,  to the extent required by Treasury
         Regulation  Sections 1.704-1 (b) and 1.704-1T, the Adjusted Capital 
         Account Deficit of such Partner as quickly as possible. It is intended
         that this  clause  (4) qualify  and be  construed  as a qualified
         income  offset  within the  meaning of Treasury Regulation Section 
         1.7041(b)(2)(ii)(d).

                 (5)      If special allocations are required under clauses
         (2), (3), and/or (4) in any fiscal year, such allocations shall be
         made in the priorities required by Treasury Regulation Sections 
         1.704-1(b) and 1.704-1T.

                 (6)       "Nonrecourse deductions" (within the meaning of
         Treasury  Regulation Section 1.704-1T(b)(4)(iv)(b)) for any fiscal year
         or other period  shall be specially allocated to the Partners  in
         proportion to their Units in the Partnership. Partner nonrecourse
         deductions (within the meaning of Treasury  Regulation  Section
         1.704-1T(b)(4)(iv)(h)(3)) for  any  fiscal  year  or  other period
         shall  be specially allocated to the Partner who  bears the economic
         risk of loss with respect to the partner nonrecourse debt (within
         the meaning of Treasury Regulation Section 1.704-1T(b)(4)(iv)(k)(4))
         to which such partner nonrecourse deductions  are attributable in
         accordance with Treasury Regulation Section 1.704-1T(b)(4)(iv)(h).

                 (7)      The Partners  acknowledge that  all  distributions of
         cash (including  distributions upon  liquidation of the Partnership)
         are intended to  be made in accordance  with the priorities set forth
         in Articles V and VI and that the Partners capital  accounts are
         intended to reflect the manner in which such  distributions are
         intended to be made.  The  allocations set forth in clauses (1) (last
         sentence),  (2), (3),  (4), and (6)  (first sentence)  (the
         Regulatory Allocations )  are intended to comply  with certain
         requirements of  Treasury Regulation Sections 1.704-1(b) and
         1.704-1T(b)(4), but may result  in distortions of  the Partner's
         capital accounts  in relation to  the distributions that each Partner
         is intended to receive  from the Partnership.   Notwithstanding any
         other  provisions of this Article  VII (other than the  Regulatory
         Allocations), the Regulatory  Allocations shall be taken into account
         in allocating  other Profits,  Losses and items  of income,  gain,
         loss and  deduction to  the Partners so that, to the maximum extent
         possible, at any point in time the Partners'  capital  accounts shall
         reflect the manner  in which distributions  would be made  to the
         Partners,  if the Partnership were  liquidated and the proceeds  of
         such liquidation were distributed  to the Partners in accordance with
         Articles VI and XVIII.

                    ARTICLE VIII.  APPLICATION OF PROCEEDS

         Net Proceeds will be used solely for the conduct of Partnership 
operations.

         In  view of  the  fact that  Partnership  activities will  not
commence until  sales  are closed  and Partnership  operations commence,
Benton  and  Energy Partners  reserve  the  right to  change  the estimated
allocation of  Proceeds,  as described  below,  in  the best  interest  of the
Partnership.   However,  it  is anticipated  that the  Net Proceeds  will be
applied by  the Partnership  on the  basis  of  approximately the following
percentages:

</TABLE>
                     ARTICLE IX. FORMATION OF PARTNERSHIP

         In the sole discretion of  the Co-Managing General Partners, the
Partnership may be  formed as soon as the  minimum  Subscriptions ($250,000)
have  been raised.  Additional Participants  may  be  admitted to  the
Partnership until the  Offering Termination Date, as  extended.  From the time
the minimum  Subscriptions have been received and the Partnership formed until
the Offering Termination




                                      12
<PAGE>   13
Date  or final closing date, the Partnership  will close at the  end of each
month  and admit new Participants and  will acquire either a greater working
interest in the  Proven Producing Properties previously acquired or will
acquire interest in additional Proven Producing Properties.

         At the sole  discretion of  the Co-Managing  General Partners, the
Partnership may  continue to  have monthly closing  dates until such time  as
the Offering  Termination Date occurs or  the Partnership sales  are closed.
Once the  final  termination date  has  occurred  or the  Partnership  sales
have  closed,  then all Participants  will share  in all  Partnership costs and
revenues on  a proportionate  basis thereafter.   The Partnership will not
engage  in any recompletions, nor  will the Partnership  drill any wells, until
the final termination date.

           ARTICLE X. TERM AND CONVERSION OF GENERAL PARTNER UNITS

         A.      The term of  the Partnership will commence on  the date of
execution  of this Agreement,  and will continue until December 31,  2040, and
will terminate  at such earlier time  as all of the  interests and properties
acquired  for the  Partnership have  been fully  depleted, disposed  of, sold
or abandoned,  unless sooner terminated as set forth in Article XVI or XVIII of
this Agreement.

         The calendar year is  the Partnership s fiscal year, subject  to
change by Benton and  Energy Partners as permitted by the Code.

         B.      Following the completion of the Partnership s drilling
activities  (but in no event prior  to January 1, 1993), at the  option of
Benton and Energy  Partners, and subject to the receipt of the  opinion of
counsel  described  below, the  General  Partner  Units may  be  converted  to
Limited  Partner  Units.   Such conversion shall occur upon  compliance with
this  paragraph B.  All  other rights and  obligations under  this Agreement
shall not be affected by such conversion.   Prior to any such conversion,
Benton  and Energy Partners shall obtain an opinion of tax counsel to the
Partnership to the effect that such  conversion would not result in any
materially adverse  federal tax consequences to the  Partnership or the General
Partners.   In order to accomplish  such  conversion,  Benton and  Energy
Partners  will  (i) amend  this Agreement  with  such changes therein  or
amendments  thereto as  are  deemed  appropriate by  Benton and  Energy
Partners and  that do  not adversely  affect the  General Partners,  (ii) file
an amended  Certificate  of  Limited Partnership  with the Secretary  of State
for the  State of  California  and (iii)  take  such other  actions as  are
necessary or appropriate to  accomplish conversion of  the General Partner
interests. Notwithstanding  the foregoing, Benton and  Energy  Partners shall
not  be  obligated  to cause  conversion  of  the Partnership  or  may delay
such conversion if Benton and  Energy Partners or  their tax counsel determine
that conversion at  that time  would not be in the best interests of the
General Partners.

                 Participants  and the Special Limited Partners during the
                 period;

                 5.       Energy Partners shall furnish a report to each

         containing such information as Energy Partners deems necessary for the
         proper presentation of federal income tax returns;

                 6.       Energy Partners shall maintain, at the principal
         office of the Partnership, copies of the Partnerships federal, state
         and local income tax returns and reports for the six (6) most recent
         years;

                 7.       Benton will purchase, at the expense of the
         Partnership, liability and other insurance to protect the Partnerships
         properties and business;

                 8.       Benton and Energy Partners may enter into any

         (25%) of the Proceeds plus all paid Assessments; provided, further,
         that in no event will the lender have the election to convert its

         status of the entity to be recognized;

                 11.      Benton may cause title to Partnership property to be

         consent of other Participants or Special Limited Partners; provided,   
         however, that any transferee of a Unit or a Special Limited Partners
         interest will receive a right to share in the profits and capital of

         prior written consent of Benton and Energy Partners, which consent may
         be given or withheld in their sole and absolute discretion; provided,
         further, that Benton and Energy Partners will withhold their written
         consent in the event that they have reasonably determined in their
         sole discretion that such substitution could have an adverse effect on
         the business activities or the legal or tax status of the Partnership,
         under either state or federal law;

                 13.      Benton and Energy Partners may admit one or more
         additional managing general partners which may become a successor
         entity to Benton and Energy Partners and take action which would have
         the effect of providing an additional and/or a successor managing
         general partner, if the holders of a majority of the Units outstanding
         approve; provided, however, that such approval of the holders of Units
         shall not be necessary if the additional managing general partner
         proposed by Benton or Energy Partners is (1) an Affiliate of Benton or
         Energy Partners; (2) an entity with which Benton or Energy Partners
         has merged; or (3) a person or entity that has purchased all or
         substantially all the assets of Benton or Energy Partners;

         activities;

                 16.      Energy Partners and Benton may amend the Agreement,
         including amending the Agreement to alter the Partnership's form so
         that it becomes a different type of business entity, for business and
         tax reasons, subject to the provisions of Article XVI;


                 17.      Energy Partners and Benton may do any and all things
         necessary or appropriate in order to accomplish the purpose of the
         Partnership, subject to the provisions of this Agreement;

                 18.      Energy Partners and Benton may conduct other oil and

         commence prior to, during or subsequent to the Partnership;

                 19.      Benton may purchase assets from the Partnership in
         connection with a dissolution of the Partnership, at a price which is
         the greater of the then fair market value (which term shall mean the
         value of the assets as determined by an independent oil an gas
         engineer) or the highest bona fide offer for such assets by a third
         party, if any, regardless of any difference between such fair market
         value and the original cost to the Partnership of such assets (subject
         to the approval of a majority in interest of the Participants if the
         asset represents five percent (5%) or more of the initial value of the
         assets of the Partnership);

                 20.      Energy Partners may make any and all elections for 
         purposes of federal, state or local income taxes that it deems 
         appropriate; and

                 21.      Benton and Energy Partners may submit a partnership
         claim or liability to arbitration or reference, assign the Partnership
         property and trust for creditors or on the assignee s promise to pay
         the debts of the partnership, confess a judgment or dispose of the
         goodwill of the Partnership for adequate consideration.

         B.      Benton and  Energy Partners shall have  no authority on behalf
                 of the Partnership or themselves to:

                 1.       Do any act in contravention of this Agreement;


                 2.       Use Partnership property or commingle any Partnership
         bank accounts or monies with funds of Benton, Energy Partners or their
         Affiliates, or to make advances to Benton, Energy Partners or their
         Affiliates, except where necessary to secure tax benefits of prepaid
         drilling and completion costs, and in no event will such advances
         include non-refundable payments for capital completion costs prior to
         the time that a decision is made that the well warrants such
         equipment;

                 3.       Take any action with respect to partnership assets or
         property which does not primarily benefit the Partnership, including,
         among other things, the utilization of Partnership funds as
         compensating balances for its own benefit, and the commitment of
         future production n not in the best interests of the Partnership;

                 4.       Make any loans of Partnership funds to Benton, Energy
         Partners or their Affiliates;

                 5.       Make or institute any marketing arrangements or other
         relationships affecting the property of the Partnership where the
         benefits are not fairly and equitably apportioned according to the
         respective interests of all parties; or

                 6.       Knowingly enter into any arrangements involving
         working interests in any oil and gas property which commit the working
         interest to be held in an entity which limits the liability of the
         General Partners as to the working interest so as to cause the working
         interest to be considered a passive activity so that losses from the
         working interest may only offset passive activity income as set forth
         in Code Section 469.



         C.   The  following prohibitions  and restrictions  shall be
              applicable to Benton:

              1.       If Benton sells, transfers or conveys all or any 
         portion of a lease to the Partnership, Benton must, at the same time, 
         sell, transfer, or convey to the Partnership an equal proportionate 
         interest in all its other leases in the same Prospects.




                                      17
<PAGE>   18
                 2.       A sale, transfer, or conveyance to the Partnership of
         less than all of the ownership of Benton or its Affiliates in any
         portion of a lease (the Subject Portion  ) is prohibited unless the
         interest retained by Benton or its Affiliates is a working interest,
         the respective obligations of Benton or its Affiliates and the
         Partnership to pay costs with respect to the Subject Portion are
         proportionate to their respective working interests after the
         transfer, and Bentons or its Affiliates  interest in the revenues does
         not exceed any amount proportionate to its retained working interest.
         Benton or its Affiliates may not retain any overrides or other burdens
         on the Subject Portion, and may not enter into any farmout
         arrangements with respect to its retained interest, except to
         nonaffiliated third parties or other partnerships sponsored by Benton.
         For the purposes of this paragraph, the term Affiliate   shall not
         include another partnership where the interest of Benton is identical
         to, or less than, Benton s interest in the Partnership.

                 3.       Benton may never profit by drilling in contravention
         of its fiduciary obligation to the Partners. All services provided to
         the Partnership by Benton or its Affiliates will be embodied in a
         written contract which precisely describes the services to be rendered
         and all compensation to be paid.



            ARTICLE XII.  COMPENSATION OF BENTON AND ENERGY PARTNERS

         Benton  maintains  a staff  of  geologists,  engineers and  land
personnel  who  are responsible  for screening  and acquisition of leases and
for conducting drilling and producing  operations.  The costs incurred in
maintaining these departments, including salaries of personnel,  are allocable
in past to  the Partnership's activities  and are included in Partnership
Costs. Such costs shall  be paid or  reimbursed by the Partnership out of
Proceeds or revenues.

         Benton and Energy  Partners will also be  reimbursed for General and
Administrative Expenses incurred on  behalf of  the Partnership  as  a fee  for
the first  twelve (12)  months  of Partnership  operations and thereafter  as a
reimbursement of expenses incurred. The amount of the fee  which will be
allocated entirely to the Participants for the first twelve (12) months  of
Partnership operations will be three  percent (3%) of the Participants'
Subscriptions.

         Signal Securities, Inc. will receive  a wholesaling fee of up to three
percent (3%) of the total Units sold by the broker/dealers for which Signal
acts as a wholesaling broker/dealer.

         As set  forth in Article  Vl, Benton  and Energy  Partners will share
in Partnership  revenues in  an amount  in excess  of  their contribution  to
Partnership  costs.  The Participants  and  the Special  Limited Partners
consent to the receipt by  Benton, Energy Partners and  their Affiliates of
the benefits and profits set forth in this Article.


                    ARTICLE XIII.  PROTECTION OF THE PARTIES


         In any  threatened, pending or  completed action, suit  or proceeding
to which  the either of  the Co-Managing General Partners was or is a party or
is threatened to be made a party by reason of the fact that




                                      18
<PAGE>   19
it was or is a Co-Managing General Partner of the Partnership (other than  an
action by or in the right  of the Partnership) involving  any alleged cause of
action for damages  arising from the performance  of oil and  gas activities,
including  exploration,  development,  completion,  operation, or  other
activities  relative to management  and disposition of oil and  gas properties
or production from such properties, the Partnership will indemnify the
Co-Managing General  Partners against expenses, including attorneys  fees,
judgments and  amounts paid  in  settlement actually  and  reasonably  incurred
by  them  in  connection  with  such  action, suit  or proceeding if they
acted in good faith and  in a manner they  reasonably believed to be in or not
opposed to the best  interests  of the  Partnership,  and  provided that  their
conduct  does  not constitute  negligence, misconduct or a  breach of their
fiduciary  obligations to the Participants and the Special  Limited Partners.
The termination  of any  action, suit or  proceeding by  judgment, order or
settlement shall  not, of  itself, create a presumption  that Benton or  Energy
Partners did  not act  in good  faith and in  a manner which  they reasonably
believed to be in or not opposed to the best interests of the Partnership.

         In  any threatened,  pending or  completed action  or  suit by  the
Partnership  in the  right of  the Partnership,  to which a Co-Managing
General Partner was or  is a party or  is threatened to  be made a party,
involving an alleged cause  of action by a Participant  or a Special Limited
Partner  for damages arising from the activities of a  Co-Managing General
Partner in  the performance of  management of the internal  affairs of the
Partnership as  prescribed by  this Agreement,  the Partnership  will indemnify
the  Co-Managing General Partner against  expenses, including attorneys   fees,
actually  and reasonably incurred by  it in  connection with the defense or
settlement of such action or suit if it  acted in good faith and in a  manner
it reasonably believed  to be in or  not opposed to the best interests  of the
Partnership, as  specified in this paragraph, except that  no indemnification
shall  be made  in respect  of any  claim, issue or  matter as  to which a  Co-
Managing  General Partner  shall have  been adjudged  to be  liable for
negligence, misconduct  or  breach of fiduciary obligation in  the performance
of its duty to the Partnership unless and only to the extent that the court in
which  such action  or  suit  was  brought  shall determine  upon  application,
that,  despite  the adjudication of  liability, but in  view of all
circumstances of the  case, a Co-Managing  General Partner  is fairly and
reasonably entitled to indemnity for such expenses which the court shall deem
proper.

         To the  extent that a Co-Managing  General Partner has been
successful on the merits  or otherwise in defense of any  action, suit or
proceeding referred to above,  or in defense  of any  claim, issue or  matter
therein, the  Partnership  shall  indemnify  a Co-Managing  General  Partner
against the  expenses,  including attorneys  fees, actually and reasonably
incurred by  it in connection therewith. Any such  indemnification of a
Co-Managing  General Partner shall  be prohibited unless  the Co-Managing
General Partner has  determined in good faith  that the course  of conduct
which  caused the loss  or liability  was in  the best interest  of the
Partnership;  that such liability  or loss  was not  the result  of negligence
or misconduct by  a Co-Managing General Partner;  and that indemnification  of
a  Co-Managing General  Partner or  its Affiliates  will not  be allowed  for
any liability  imposed by  judgment, and costs associated  therewith, including
attorneys'  fees, arising from or  out of violation of state or  federal
securities laws associated  with the offer and  sale of Partnership Units.
Indemnification will  be allowed for settlements and  related expenses of a
lawsuit alleging securities law violations, and for expenses incurred in
successfully defending such lawsuits, provided  that a court  either: (a)
approves the  settlement and  finds indemnification  of the  settlement  and
related costs should be made or (b) approves indemnification of litigation
costs if a successful defense is made.

         Any indemnification, unless ordered  by a court, shall be  made by the
Partnership only  as authorized in the specific case and only upon a
determination by independent legal counsel in a written


                                      19
<PAGE>   20
opinion that indemnification  of a Co-Managing General  Partner is proper  in
the circumstances  because a Co-Managing General Partner has met the
applicable standard of conduct set forth above.

         The indemnification of a Co-Managing  General Partner shall be limited
to and recoverable  only out of the assets of the  Partnership and not against
any Limited Partner  or General Partner and  indemnification of the Co-Managing
General Partners  as to a third party  is only with respect to such loss,
liability  or damage not otherwise compensated for by insurance carried for the
benefit of the Partnership.

         The Partnership  may not  incur the  cost of  that portion  of
insurance which  insures a  Co-Managing General  Partners from  any liability
as to  which the Co-Managing  General Partner  is prohibited  from being
indemnified under this Article.

         The General Partners  hereby agree  that each shall  be solely and
individually responsible only  for their pro  rata share of the  liabilities
and obligations  of the Partnership, and  any Participant who  incurs liability
in excess of his pro rata share shall  be entitled to contribution from the
other  General Partners.  Pursuant thereto, each Co-Managing  General Partner
further agrees to  indemnify each Participant from  paying any  liabilities or
obligations of  the Partnership  in  excess of  such Participant s  capital
contribution.  Furthermore,  although the General  Partners may  be personally
liable  for the liabilities  and obligations to the Partnership,  all such
liabilities and  obligations shall  be paid  or discharged  first with
Partnership assets  (including insurance proceeds) before the General Partners
shall be  obligated to pay or discharge any liability or obligation with their
personal assets.


                        ARTICLE XIV.  RELATED PARTIES

         Benton and Energy  Partners and  their Affiliates or  related persons
or entities may  be engaged  or employed by the Partnership to  render or
perform services for the  Partnership and/or may sell property of any kind or
description  to  it,  or may  otherwise  engage  in  transactions  with  the
Partnership.  All  such engagements, employments  and other transactions  shall
not be invalidated by reason  of any such relationships so  long as such person
is  engaged, independently of the Partnership and as  an ongoing business in
rendering such services or selling such equipment  and supplies to a
substantial extent  to other persons and such prices and terms are not higher
than those normally charged in  the same geographic area by  unaffiliated
persons or companies dealing at arm's length. If the person is  not engaged in
business as provided above, then the price of such services shall be the cost
of  such services, equipment or supplies to such  person or the competitive
rate  in the geographical area,  whichever is less. Benton and  Energy Partners
may be  presently conducting or may conduct  in the  future other  oil and  gas
income,  drilling and acquisition  programs which  may commence during  or
subsequent to this Partnership.  All contracts entered  into between the
Partnership, Benton, Energy Partners and their Affiliates or related  persons
or entities shall  be terminated without penalty on not  less than thirty  (30)
days  written  notice by the Partnership or  on sixty (60)  days  written
notice  by Benton, Energy Partners or their Affiliates.

         The leases transferred to  the Partnership by Benton  or its
Affiliates shall  be sold at Cost  unless Benton  believes that the appraised
value is  substantially lower than Cost.  In such a case  the value of the
lease will be determined by an independent appraiser and sold at the lower of
Cost or appraised value.

                 ARTICLE XV. RESTRICTIONS ON TRANSFERABILITY



                                      20
<PAGE>   21
         No  Participant  or Special  Limited Partner  shall have  the power
to sell,  assign or  transfer his interest in the Partnership or to cause a
transferee to  become a substituted Partner except upon the  written consent of
Benton and Energy  Partners. Each Participant  and Special Limited  Partner
specifically agrees  to the admission of any  substituted Partner as a Partner
when consented to by Benton and  Energy Partners. Benton and Energy Partners
shall review any  proposed transfer  and shall  withhold their consent  In the
event  they determine, in their sole  and absolute discretion, that such
substitution  could have an adverse effect on  the business  activities or the
legal or  tax status  of the  Partnership or  the remaining partners  under
either state or federal law.

         Each of Benton and  Energy Partners may sell, assign, transfer, pledge
or  encumber all or any portion of its  rights  to  receive  revenues  as a
Co-Managing  General  Partner under  this  Partnership  Agreement; provided,
however,  that  the  assignment of  such  revenue  interest  shall  not affect
Benton's  and  Energy Partners'  other rights and obligations pursuant to this
Agreement.

         In  addition to the  restrictions upon  substitution of an  additional
Participant or  Special Limited Partner,  neither a  Participant nor a Special
Limited Partner may sell  his rights to profits  and capital In the Partnership
without furnishing Benton  and Energy Partners with a  copy of the offer to buy
such  interest and giving Benton  and Energy Partners the prior right for a
period of ten (10)  days after receipt of written notice, to  purchase such
interest on  the  terms contained  in such  offer. In  the event  Benton and
Energy Partners do not exercise their prior right to purchase such interest in
profits  and capital within a ten (10) day period or notify  the Participant or
Special  Limited Partner that such  right will not  be exercised,  the
Participant or Special Limited Partner shall have the right to sell his
interest in profits and capital  for a period  of forty-five (45)  days.
Thereafter, the Participant  or Special Limited  Partner shall  not sell any
part of his interest in profits and capital  without again offering the same to
Benton  and Energy Partners.  A transferee of a  Partner s right to profits
and capital who is  not admitted as a  Partner is not entitled to any of  the
rights of a Partner.  A  transferee Participant or Special  Limited Partner has
no greater right to terminate the Partnership than his transferor.

         In no event shall  any assignee or transferee hold less  than one Unit
except by gift  or operation of law.

               ARTICLE XVI.  RIGHTS, AUTHORITY AND LIABILITIES
                 OF PARTICIPANTS AND SPECIAL LIMITED PARTNERS

         A.   RIGHTS

         By a majority vote of  the outstanding Units, the Participants (but
not the  Special Limited Partners) shall have the right to:

                 1.       Remove Benton, Energy Partners and/or any successor
         Co-Managing General Partner; terminate all contracts between the
         Partnership and Benton, Energy Partners and their Affiliates; allow
         Benton, Energy Partners or their Affiliates to remove all of their
         property interests in the Partnership; and select a substitute
         managing general partner or additional general partner to continue the
         business of the Partnership;

                 2.       Amend the Agreement, subject to the written consent
         of Benton and Energy Partners concerning matter affecting their
         interests in profits, losses, credits and property;



                                      21
<PAGE>   22
                 3.       Terminate the Partnership;

                 4.       Approve the sale or exchange of all or substantially
         all of the assets; and/or

                 5.       Approve the admission of an additional general
         partner proposed to be admitted as a Co-Managing General Partner by
         Benton and Energy Partner, subject to the right of Benton and Energy
         Partners to admit certain parties as general partners without the
         consent of the Participants, as provided in paragraph 13 of Article
         XI.


         Either the Participants, upon  the written request of ten  percent
(10%) of the outstanding  Units, or Benton or Energy  Partners can cause a
vote to be taken with respect to the  matters referred to above. Notice of  a
meeting of the  Participants will be mailed  to the Participants within  ten
(10) days  of the receipt of such written notice unless  compliance with
federal or  state laws or regulations  requires additional time. A meeting will
be held  within sixty (60)  days of  the mailing of  the notice.  The presence,
in person  or by proxy,  of the holders of a  majority of the Units outstanding
shall constitute  a quorum and Participants may vote in  person or by  proxy at
any such  meeting. If a  quorum shall  not be present or  represented at  any
meeting, a majority  of the holders of Units  entitled to vote at  the meeting,
who  are present in person  or represented  by proxy, may adjourn  the meeting
from  time to  time, without notice other  than announcement at the meeting,
until a  quorum shall be present  or represented. At  any reconvening  of an
adjourned meeting  at which  a  quorum shall  be  present or  represented,  any
business may  be  transacted which  could  have been transacted  at the
original meeting  if  a quorum  had been  present  or represented.  No matters
that  would constitute taking  part in control of the Partnership  by the
Participants shall  be considered at any meeting.  In order to facilitate  the
above rights, each Participant shall have  a right to receive by mail the
complete list of names, addresses and interests of all other Participants, upon
written request to Energy Partners.

         Any action that  may be taken at  a meeting of the  Participants may
be taken  without a meeting if  a consent in  writing setting  forth the action
so taken  is signed  by Participants owning not  less than  the minimum Units
that would  be  necessary to  authorize or  take such  action at  a meeting  at
which  all  the Participants  were present and voted. Prompt notice of  the
taking of action without  a meeting shall be given to the Participants who have
not consented in writing.

         Benton and Energy Partners  shall have the right to  amend the
Agreement; provided, however,  that the Agreement shall  not be amended by
Benton and Energy  Partners in any material  respect which would  adversely
affect the  rights of the Participants  except by  the affirmative vote  of not
less than  a majority of  the outstanding amount of Units.

         In the event  that the Participants vote to remove Benton or Energy
Partners and substitute a new Co-Managing General  Partner pursuant to
paragraph A of  this Article XVI, the  Partnership or the new Co-Managing
General Partner shall purchase the entire interest of

         Benton or Energy  Partners, including their interest in capital and
revenues on an assumed dissolution basis, at a price determined by mutual
agreement  or by independent appraisal by a  petroleum engineer selected by
mutual  agreement. Such  purchase shall  provide for  payment in  full, or
assignment to  Benton or  Energy Partners  of a direct  interest in  each
Partnership  asset and/or  liability equal  to their then  interest in revenue
and capital as determined  above. Such payment or assignment shall occur  at
the time of amendment  of the Agreement and substitution of the new Co-Managing
General Partner.



                                      22
<PAGE>   23
         B.   AUTHORITY

         No Participant or Special  Limited Partner other than a  Co-Managing
General Partner has the  power to manage or conduct  Partnership business, to
act in the ordinary  course of business for the  Partnership or to sign for  or
to bind the  Partnership or any  of its Partners and  no such actions will be
considered to have been authorized by the other Partners.


         C.   LIABILITY

         No Limited  Partner shall be personally liable for  any of the debts
of the  Partnership or any of the losses thereof;  provided, however, that the
amount committed by  him to the capital  of the Partnership,  any return
thereof, and  his interest in the Partnership's  undistributed profits shall
be subject to  liability.  Additionally,  a  Limited  Partner  may  be  liable
for  wrongfully  distributed  profits  and   interest  on distributions in
return of capital.

         If a  Limited Partner receives the  return of any part  of his
contribution without  violation of this Agreement or  the  California Revised
Limited Partnership  Act, he  shall  be liable  to the  Partnership  as
provided by  such Act  for the  return of the amount  of the  returned
contributions  but only  to the  extent necessary to  discharge the
Partnership's liabilities  to creditors  who extended  credit to the
Partnership during the period the contribution was held by the Partnership.

         D.   MISCELLANEOUS

         No Participant or  Special Limited  Partner has any  right of
repayment of his  contributions to  the Partnership except  as expressly
provided  in this  Agreement. Participants  have  no right  to  vote on  any
Partnership  matters except as  set forth in this  Agreement. Special Limited
Partners have  no voting rights except as provided by  law. The Participants
and Special  Limited Partners agree that they will not  request a decree of
dissolution  from a  court until  a  majority  vote of  the outstanding  Units
of Participants  has approved such decree.

            ARTICLE XVII. WITHDRAWAL OF BENTON OR ENERGY PARTNERS

         A.   EVENTS REQUIRING CONSENT OF ALL PARTNERS TO AVOID WITHDRAWAL

         Except as waived in  writing by all Partners at the time, Benton,

pays  all expenses incurred as  a result of its withdrawal; (2) Benton, Energy
Partners or  a General Partner is removed as a General Partner in accordance
with the terms of the  Agreement; (3) in the case of a General  Partner who is

Energy  Partners or a General Partner that  is a corporation, the dissolution
of the corporation or the revocation of its charter; (7) in the case of an
estate,



                                      23
<PAGE>   24
the distribution by the fiduciary of  the estate s entire interest in the
Partnership;  or (8) In the case of a General Partner that is any other legal
entity, the cessation of the legal existence of the legal entity.

         Upon withdrawal, a  General Partner other than  Benton or Energy
Partners  shall retain all rights  to its  proportionate share of  revenues and
capital,  but shall cease  to have any vote  or engage in  any other activities
as a General Partner. The  withdrawing General Partner will have the right to
transfer his  interest subject to provisions of Article XV hereof.

         B.   EVENTS NOT CAUSING WITHDRAWAL

         Neither Benton, Energy Partners  nor any other General Partner shall

Partner's properties.

                         ARTICLE XVIII.  DISSOLUTION

         A.      The   parties  specifically   agree  that  the  retirement,
resignation,  expulsion,  death, incompetency, bankruptcy, insolvency,
dissolution, withdrawal, conveyance  of the interest of  a Participant or
Special  Limited Partner,  or admission  of  a  new partner,  or express
decision of  a Participant  shall not dissolve  the  Partnership. In  such
event,  the heir,  legal  representative,  successor  or  assign of  such
Participant or Special Limited Partner, as the case  may be, shall become an
assignee of such Participant's or Special Limited Partner's interest. Such
assignee  shall not have the rights of a substituted Partner,  unless (i)  such
heir,  legal  representative, successor  or  assign  shall  execute an
addendum  to this  Agreement, agreeing to  be bound by all of the terms  and
conditions hereof and  to assume all of the  obligations of the deceased or
incapacitated Participant  or Special Limited  Partner hereunder and  (ii) both
Benton  and Energy Partners shall have consented  to such substitution, which
consent may be  given or withheld in their sole and absolute  discretion. When
a Participant  or Special  Limited Partner  dies or  retires and  the  business
is continued, the  Participant, Special Limited Partner or his  estate has no
right to require  the Partnership or the  remaining Participants  or  Special
Limited Partners  to make  an evaluated  purchase of  his Partnership interest.

         B.      If,  notwithstanding the intent of the  Partners as set forth
in paragraph A. above, any event listed in paragraph A results in  the
dissolution of the  Partnership, such dissolution shall be considered  in
contravention of  the Agreement, and  the Partnership shall  be continued or
reconstituted. In  the event that the Partnership is dissolved,  despite the
intention of  the Partners, through any  acts pursuant to paragraph A. above,
the Partners agree that Energy Partners may take  any action which it deems
necessary  or appropriate to continue the partnership or to  reform the
Partnership on terms as  Identical as possible to this Agreement.  In  the
event that Energy  Partners causes a continuation or  reformation of the
Partnership,  the liability of all Partners will be deemed to continue
uninterrupted.

         C.      The following actions shall cause  a dissolution of the
Partnership,  provided that Benton or Energy  Partners cannot  take any
voluntary  action to cause  dissolution between the time  it receives notice
from the  Participants of  their intent  to remove  a Co-Managing  General
Partner  and the  completion of  the voting and the actions, if any, authorized
by the voting:

                 1.       The transfer or assignment of the entire interest of
         Benton or Energy Partners unless a remaining Co-Managing General
         Partner agrees to continue the Partnership;

                 2.       The written vote or consent by Participants
         representing a majority of the outstanding Units and as further
         provided by Article XVI;

                 3.       The conduct of the Partnership becoming unlawful;

                 4.       The disposition of all or substantially all of the
         assets of the Partnership;


                 5.       The expiration of the term of the Partnership as
         provided in Article X;
         
                 6.       An event of withdrawal or expulsion of Benton and
         Energy Partners, unless at the time there is at least one other
         General Partner who carries on the business of the Partnership;
         provided, however, that the Partnership is not dissolved and is not
         required to be wound up by reason of any event of withdrawal if,
         within ninety (90) days after the withdrawal, all remaining Partners
         agree in writing to continue the business of the Partnership and to
         the appointment of one or more managing general partners if necessary
         or desired; or

                 7.       The entry of a decree of judicial dissolution.

         Any dissolution caused by an event  other than those events listed
above as causes of dissolution will be considered a dissolution in
contravention of this Agreement.

         D.      Upon dissolution and winding up of  the Partnership, all of
the  assets of the Partnership may be liquidated, and all Partnership assets
shall be applied in the following order:

                 1.       To creditors, including Partners  who are creditors,
         to the extent  permitted by law, in satisfaction  of  liabilities of
         the  Partnership other  than  liabilities for  distributions  to
         Partners; then

                 2.       To Partners in proportion to their positive capital
         account balances.

         With  respect to the distributions made in liquidation, Partners who
are not otherwise creditors shall not have  the status of  and be entitled to
the remedies available  to a creditor of the  Partnership. In the event of a
distribution of assets in  kind, all assets to be  distributed to the
Participants and  the Special Limited Partners shall be distributed to an
independent trustee  who shall hold title for the benefit  of such participants
and Special Limited Partners,  collect and distribute  to such Participants
and Special Limited Partners all  of the net income  from such properties
and/or sell such properties  as such independent trustee deems to  be in the
best interests  of, and at the expense of, the Participants  and Special
Limited Partners.  The independent trustee shall operate the liquidating trust
arrangement for so long as is



                                      25
<PAGE>   26
necessary to sell or exchange Partnership  Assets for cash on  terms which the
trustee deems to be in  the best interest of the Participants and Special
Limited Partners.

         In the event  the liabilities of the  Partnership exceed its assets
upon liquidation or otherwise  if any General  Partner then has a negative
balance  in its capital account,  the General Partners must contribute funds to
the  Partnership, within the period required by Treasury Regulation Section
1.704-1, in the ratio of their negative capital  accounts until  negative
capital accounts  are eliminated. In  the event any  General Partner fails to
make the required contribution,  Benton and Energy Partners agree to pay the
amounts required, and  no Participant or  Special Limited Partner  shall have 
any liability  for the  amounts not  contributed by  other Participants.
        
         Upon  termination of the Partnership, a statement shall be prepared by
the certified public accountant employed by the Partnership setting  forth the
assets and liabilities of  the Partnership and the distribution of cash  or
property of the Partnership  as prescribed above, and a copy of such  statement
shall be furnished to each Partner within ninety (90) days after completion of
winding up of Partnership business.

         For purposes  of the  liquidation of  Partnership assets, the
discharge of  its liabilities,  and the distribution of  the remaining funds
and/or  assets among the  Partners as above described,  in the event  that all
Partnership  property  is  not  sold,  or  in  the  sole discretion  of  Benton
cannot  be  sold  so that distributions in kind  to the Partners are
appropriate  or necessary, Benton and  Energy Partners shall  cause all
Partnership  assets to be appraised by a  competent, qualified appraiser. Any
excess of fair market value, as evidenced by such appraisal,  over book value
of any Partnership assets and  any excess of book value  over such fair  market
value of any Partnership  assets shall be deemed gains or losses of  the
Partnership, as the case may be, and subject to the provisions  of Articles V
and VI, above, Benton  and Energy Partners shall have the authority on  behalf
of the  Partnership to  sell, convey,  exchange, buy back,  or otherwise
transfer  the assets  of the Partnership upon such terms and conditions as it
determines  appropriate subject to the terms of this Agreement.  A  reasonable
time shall  be  allowed  for  the orderly  liquidation  of  the assets  of  the
Partnership to  minimize normal  losses of  the liquidation  period. Any return
of all or  any portion  of the contributions by a Partner to the capital of the
Partnership  shall be made solely from or out  of Partnership assets and Benton
and Energy Partners shall not be personally liable for any such return.

                   ARTICLE XIX.  ASSESSMENTS AND BORROWINGS

         The  Participant are  subject  to  the payment  of  one  or  more
Assessments  as  additional  capital contributions to  the Partnership.  No
Assessment  shall be  made, however,  to unless  and until all  original
Proceeds have been expended or committed. The  failure of one or more
Participants to  pay any Assessment does not result  in personal  liability,
but  will result  in the  dilution of  such Participants  interest In  all
Partnership revenues and costs.  A Participant's interest in the Participants'
share of Partnership  revenues is based on  the ratio that the sum  of his
Subscription and paid Assessments bears to the total sum of all Participants'
Subscriptions and Assessments paid by all Participants (including  Benton and
Energy Partners to the  extent they pay non-consenting Participants'  shares of
Assessments). The failure of a Participant to pay his share of an Assessment
will reduce  this ratio accordingly,  as of the closing of  the pre-Assessment
or Assessment period. to one  or more Participants  fail to pay such
Assessment, Benton and  Energy Partners  may contribute  the  nonconsenting
Participants'   shares  of such  Assessment,  at  their  election,  which  will
proportionately  increase the interest of Benton and Energy partners in all
Partnership revenues and costs, on the same basis as Benton and Energy Partners
were a




                                      26
<PAGE>   27
Participant.  If the Participants fail to  pay an amount  equal to at least
fifty percent (50%)  of the total Assessment requested,  Benton or Energy
Partners have the option  of either returning to  the Participants all
Assessments contributed,  or contributing the  non-consenting Participants'
shares of such  Assessment. If the amount contributed  by the Participants
equals  or exceeds  fifty percent (50%)  of the  Assessment requested, Benton
or  Energy Partners may contribute all or a portion of the  non-consenting
Participants'  shares of such Assessment and also  may reduce the Partnership's
participation in the Prospect for which the  Assessment was made by entering
into a farmout agreement with respect to such Prospect.

         The cumulative  amount of Assessments shall  not exceed twenty-five
percent (25%) of the  Proceeds of the Partnership.

         After the Partnership  has expended or committed its  Proceeds for
property acquisitions  and drilling operations,   Benton  and  Energy  Partners
may  finance  necessary  additional   operations  by  Partnership Assessments,
use of  Partnership revenues,  or  borrowings.  Assessments may  be levied  by
Benton  and Energy Partners only  for the  purpose of  conducting subsequent
operations on  Prospects upon  which evaluation  had begun during the
Partnership's initial operation or on  leases sufficiently related to  such
Prospects as  to merit, in Benton's and  Energy Partners'   judgment, additional
operations to  fully develop those Prospects  or to acquire additional
undeveloped leases  located on the geological feature or  features of Prospects
owned by the Partnership in order to fully develop and protect its Prospects.

         Benton and Energy Partners  will give written notice to each
Participant of  the nature and purpose of any  Assessment,  the  Participant's
proportionate share  of  the  estimated  costs,  and  the  effect of  the
Participant's not  participating in the Assessment. A Participant may elect to
participate in an Assessment by notifying Benton and  Energy Partners of  his
intention  to participate and  sending the requested  payment by mail within
twenty (20) days after  Benton and Energy Partners mail the written Assessment
notice, unless  such period  is  extended by  Benton  and Energy  Partners.
Any  participant shall  be  deemed to  have  refused to participate in any
Assessment by notifying Benton  and Energy Partners of his  election not to
participate  or by  failure to pay his  share of the Assessment when due. In
the  event that the proportionate interests of the Partners change  by reason
of  Assessments, solely  for the  purpose of  allocating costs  and revenues,
there shall be an  interim closing of  the Partnership  financial books
immediately  upon closing of  the Assessment period, with all  allocations made
as  of the date  of the interim closing according  to the interests  of the
partners immediately prior to  payment of the Assessments.  The pre-Assessment
or Assessment period closes  on the last day established by Benton and Energy
Partners for the payment of an Assessment by the Participants.

         Benton  intends  to  develop  the  Partnership's Prospects  fully
through  the  initial  Proceeds and Assessments. However,  no assurance  can be
made that such  funds will be  sufficient. If  such funds are  not sufficient,
the  Partnership may borrow the necessary funds, may  farm out the undeveloped
portion of certain Prospects, or may sell or abandon certain undeveloped
leases.


                         ARTICLE XX.  POWER OF ATTORNEY

         The Participants  and the  Special Limited  Partners constitute  and
appoint  Energy Partners and  its successors  and  assigns, with  full  power

amendment is made pursuant to Article XVI.

Gentlemen:

  We have acted as counsel for Benton Oil and Gas Company (the "Company") in
connection with the registration under the Securities Act of 1933, as amended,
of up to _______ shares of common stock, $0.01 par value per share (the
