              Notes to Consolidated Condensed Financial Statements
                                December 31, 1997
                                   (unaudited)


(1)    General

       The information furnished reflects all adjustments which are, in the
       opinion of management, necessary to a fair presentation of the results of
       the interim periods presented. The results of operations for the three
       and six months ended December 31, 1997 are not necessarily indicative of
       the operating results for the full fiscal year ending June 30, 1998.
       Moreover, these financial statements do not purport to contain complete
       disclosure in conformity with generally accepted accounting principles
       and should be read in conjunction with the Company's audited financial
       statements at, and for the fiscal year ended June 30, 1997.

       In June 1997, the Financial Accounting Standards Board issued Statement
       of Financial Accounting Standards No. 130, Reporting Comprehensive Income
       ("SFAS 130"). SFAS 130 establishes standards for reporting and display of
       comprehensive income and its components in a full set of general-purpose
       financial statements. SFAS 130 is effective for fiscal years ending after
       December 15, 1997. The adoption of SFAS 130 will require additional
       disclosures in the Company's financial statements, but the Company
       believes that it will not have any material impact on the financial
       position or results of operations of the Company.

(2)    Common Stock

       Loss per common share is based on the weighted average number of common
       shares outstanding (27,285,783 and 22,031,259 for the three and six
       months ended December 31, 1997, respectively, and 27,123,739 and
       27,204,761 for the three and six months ended December 31 1996,
       respectively).

       In 1997, the Financial Accounting Standards Board issued Statement of
       Financial Accounting Standards No. 128, Earnings per Share. Statement 128
       replaced the previously reported primary and fully diluted earnings per
       share with basic and diluted earnings per share. Unlike primary earnings
       per share, basic earnings per share excludes any dilutive effects of
       options, warrants, and convertible securities. Diluted earnings per share
       is very similar to the previously reported fully diluted earnings per
       share. All earnings per share amounts for all periods have been
       presented, and where necessary, restated to confirm to the Statement 128
       requirements.

       During the six months ended December 31, 1997 the Company issued 350,000
       and 200,000 restricted shares of common stock pursuant to Regulation S
       for $1,067,500 and $700,000 $(3.05 and $3.50 per share), respectively.
       The Company issued 1,000,000 restricted shares of common stock valued at
       $3,125,000 $(3.125 per share) as partial consideration for the
       acquisition of oil and natural gas producing properties in New Mexico,
       Oklahoma and Texas (see Note 3). The Company issued 150,000 restricted
       shares of common stock in consideration of services rendered, which it
       valued at $2.00 per share $(300,000).

              Notes to Consolidated Condensed Financial Statements
                                December 31, 1997
                                   (unaudited)


(3)      Acquisitions

         On August 1, 1997 the Company acquired from Collins & Ware, Inc. 77
         productive wells (12.35 net productive wells) located in various
         counties in New Mexico, Oklahoma and Texas. In consideration for these
         properties the Company paid, subject to standard industry adjustments
         at closing, approximately $6,000,000 in cash and issued 1,000,000
         restricted shares of its common stock which it valued, for purposes of
         this transaction, at $3.125 per share $(3,125,000).


(4)      Subsequent Events

         On January 8, 1998 the Company repaid two notes payable issued in
         February 1997 in partial consideration for an acquisition of oil and
         natural gas producing properties in the face amount of $2 million. The
         funds to retire these notes were drawn under the Company's senior
         secured credit agreement with the the Bank of Montreal ("the Senior
         Credit Agreement").

         The Company has entered into a subordinated revolving credit agreement
         ("the Subordinated Credit Agreement") with an affiliate of the Company.
         The Company can borrow, subject to certain restrictions, the lesser of
         $10,000,000 and 40% of the borrowing base of the Senior Credit
         Agreement. At this time the borrowing base under this Subordinated
         Credit Agreement is $6,000,000.

         On January 29, 1998 the Company issued 200,000 shares of its common
         stock for $500,000 $(2.50 per share) pursuant to the exercise of
         200,000 Class A Warrants.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
            RESULTS OF OPERATIONS

FORWARD-LOOKING STATEMENTS

All statements in this document concerning the Company other than purely
historical information (collectively "Forward-Looking Statements") reflect the
current expectation of management and are based on the Company's historical
operating trends, estimates of proved reserves and other information currently
available to management. These statements assume, among other things, (i) that
no significant changes will occur in the operating environment for the Company's
oil and gas properties, gas plants and gathering systems, and (ii) that there
will be no material acquisitions or divestitures. The Company cautions that the
Forward-Looking Statements are subject to all the risks and uncertainties
incident to the acquisition, development and marketing of, and exploration for,
oil and gas reserves. These risks include, but are not limited to, commodity
price risk, environmental risk, drilling risk, reserve, operations, and
production risks, regulatory risks and counterparty risk. Many of these risks
are described in the Company's Annual Report on Form 10-KSB for the fiscal year
ended June 30, 1997 filed with the Securities and Exchange Commission in
September 1997. The Company may make material acquisitions or dispositions,
enter into new or terminate existing oil and gas sales or hedging contracts, or
enter into financing transactions. None of these can be predicted with any
certainty and, accordingly, are not taken into consideration in the
Forward-Looking Statements made herein. For all of the foregoing reasons, actual
results may vary materially from the Forward-Looking Statements and there is no
assurance that the assumptions used are necessarily the most likely.

SELECTED FINANCIAL DATA

The following tables set forth selected financial data for the Company. The
financial data was derived from the consolidated financial statements of the
Company and should be read in conjunction with the Consolidated Financial
Statements and related Notes thereto included herein. The consolidated financial
statements for the three and six month periods ended December 31, 1997 and 1996
reflect all adjustments which, in the opinion of the Company, are necessary for
a fair presentation of the results of operations and the financial position of
the Company. The results of operations for the three and six months ended
December 31, 1997 will not necessarily be indicative of the operating results
for the full fiscal year ending June 30, 1998.

The following discussion of the results of operations and financial condition
should be read in conjunction with the Consolidated Financial Statements and
related Notes thereto included herein.

THE THREE MONTHS ENDED DECEMBER 31, 1997 COMPARED TO THE THREE MONTHS ENDED
DECEMBER 31, 1996


REVENUES The Company's total revenues rose by $782,000 (81%) to $1,748,000 for
the three months ended December 31, 1997, from $966,000 for the comparable
period in 1996. This increase is a result of an increase in the BOE's produced
offset by a 12.7% decrease in selling prices.

The Company produced 59,018 barrels of crude oil during the three months ended
December 31, 1997, an increase of 28,862 barrels (91%) over the 31,669 barrels
produced during the comparable period in 1996. This increase was comprised of a
decrease of 7,673 (28%) barrels from the properties that the Company owned
during both periods and an increase of 36,535 barrels from the properties
acquired during the period October 1, 1996 to September 30, 1997. The decrease
in production of crude oil from the properties owned during the comparative
quarters is primarily a reflection of natural depletion of the crude oil
producing reservoirs, and the temporary loss of production from certain
properties due to work overs during the three months ended December 31, 1997.

The Company produced 242,097 Mcf of natural gas during the three months ended
December 31, 1997, an increase of 137,731 Mcf (132%) over the 106,639 Mcf
produced during the comparable period in 1996. This increase consists of an
increase of 16,351 Mcf (15%) from the properties that the Company owned during
both periods and an increase of 121,380 Mcf from the properties acquired during
the period from October 1, 1996 to September 30, 1997. The increase in
production from the properties owned during the comparative quarters is a result
of the successful drilling of four new wells and the work over of certain
producing and non-producing wells, off-set by the natural depletion of the
natural gas producing reservoirs'.

The average selling price of oil was $17.96 per bbl for the three months ended
December 31, 1997, compared to $22.62 per bbl in the comparable period in 1996.
This decrease of $4.66 per bbl (21%) is a result of general decreases in oil
prices. The average selling price of natural gas was $2.07 per Mcf for the three
months ended December 31, 1997, compared to $2.34 per Mcf in the comparable
period in 1996. This decrease of $0.27 per Mcf (11%) is a result of general
decreases in natural gas prices during the three months ended December 31, 1997.

                                       8

The Company entered into agreements with Enron Capital & Trade Resources Corp.
("Enron"), an affiliate of Joint Energy Development Investments Limited
Partnership ("JEDI"), the holder of 9.6 million shares of the Company's Series A
Participating Convertible Preferred Stock, to hedge 50,000 MMBtu of natural gas
production and 10,000 barrels of oil production monthly. The agreements, which
are effective September 1, 1997, and terminate August 31, 1998, call for a gas
and oil ceiling and floor price of $2.66 and $1.90 per MMBtu of natural gas and
$20.40 and $18.00 per barrel of crude oil, respectively. If the average market
price of oil and gas per month, as defined in the agreements, exceeds the
ceiling price, the Company must pay Enron an amount equal to one-half of the
amount of the hedged quantities multiplied by the difference between the ceiling
price and the market price. If the average market price, as defined, falls below
the floor price, Enron will pay the Company an amount equal to the amount of the
hedged quantities multiplied by the difference in the floor price and the market
price. Pursuant to these hedging agreements, the Company made cumulative net
payments to Enron of $5,700 and $7,683 as a result of crude oil and natural gas
prices exceeding the ceiling prices in the agreements during the three months
ended December 31, 1997.

PRODUCTION EXPENSES The Company's lease operating expenses ("LOE's") rose to
$858,000 for the three months ended December 31, 1997, an increase of $423,000
(97%) from the comparable period in 1996. The increase is a combination of the
105% (based on BOE produced) increase in production offset by a decrease in the
LOE per BOE. The average LOE per BOE was $8.47 per BOE during the three months
ended December 31, 1997, a decrease of $0.32 (4%) over the average LOE per BOE
of $8.79 for the comparable period in 1996. Recurring LOE's, those costs
incurred in the normal operations of the Company, were $695,000 during the three
months ended December 31, 1997, or $6.85 per BOE, as compared to $419,000, or
$8.48 per BOE, during the comparable period in 1996. This represents a $1.63 per
BOE (19%) improvement. The Company believes that this improvement is a result of
improved efficiencies at an operating level and the acquisition of properties
with lower average operating costs per BOE than those the Company has owned
during the preceding years. Non-recurring LOE's, which are work over costs
incurred to increase production from existing producing reservoirs and thus are
arguably more capital in nature, but must be treated as expenses under the
Securities and Exchange Commission accounting rules, were $164,000 $(1.62 per
BOE) during the three months ended December 31, 1997, as compared to only
$15,000 $(0.30 per BOE) during the comparable period in 1996. This $149,000
(992%) increase in non-recurring LOE's is consistent with the Company's strategy
of redeveloping its properties to increase production, the objective of which is
to increase production and reduce the LOE per BOE. Early indications are that
this program will have the desired effect on production and LOE's over the long
term.

SEVERANCE AND PRODUCTION TAXES Severance and production related taxes were
$112,000 for the three months ended December 31, 1997, compared to $75,000
incurred in the comparable period in 1996. This increase of $36,000 (48%) is a
function of the 105% (based on BOE produced) increase in production offset by
the decrease in oil and natural gas prices (12% based on BOE produced).

DEPRECIATION, DEPLETION AND AMORTIZATION EXPENSE Depreciation, depletion, and
amortization (DDA) costs were $424,000 for the three months ended December 31,
1997, an increase of $179,000 (73%) over the $244,000 recognized during the
comparable period in 1996. This increase relates primarily to the 105% increase
in BOE produced. The DDA cost per BOE was $4.18 during the three months ended
December 31, 1997, a decrease of $0.76 per BOE (15%) over the $4.95 per BOE for
the comparable period in 1996. This decrease in DDA per BOE is primarily the
result of a reduction in the expected future capital costs required to bring the
Company's reserves into production.

GENERAL AND ADMINISTRATIVE COSTS The general and administrative costs of the
Company were $695,000 during the three months ended December 31, 1997, as
compared to $329,000 for the comparable period in 1996. This increase of
$365,000 (111%) consists of an unusually high, one-time expense of $300,000 for
financial public relations services. The Company issued 150,000 restricted
shares of its common stock in consideration of these services. After adjusting
for this item, general and administrative expenses rose only $65,000 (20%). On a
cost per BOE produced basis, general and administrative expenses were $6.86 per
BOE, an increase of $0.20 per BOE from the $6.66 per BOE for the comparable
period in 1996. After adjusting for the unusual item described above, general
and administrative expenses were only $3.90 per BOE.

INTEREST EXPENSE The Company incurred interest charges of $338,000 during the
three months ended December 31, 1997, compared to $170,000 for the comparable
period in 1996. This increase of $168,000 (99%) is a reflection of the increase
in the average interest bearing debt of the Company, from $8.1 million for the
three months ended December 31, 1996 to $13.8 million during the three months
ended December 31, 1997. This increase in the average interest bearing debt of
$5.7 million in debt was used primarily to finance the acquisition of more than
$9 million of oil and gas producing properties.

THE SIX MONTHS ENDED DECEMBER 31, 1997 COMPARED TO THE SIX MONTHS ENDED DECEMBER
31, 1996

REVENUES The Company's total revenues rose by $1,562,000 (88%) to $3,342,000 for
the six months ended December 31, 1997, from $1,780,000 for the comparable
period in 1996. This increase is a result of increases in both the BOE produced
offset by a decrease in selling prices.

The Company produced 119,549 barrels of crude oil during the six months ended
December 31, 1997, an increase of 61,083 barrels (104%) over the 58,466 barrels
produced during the comparable period in 1996. This increase was comprised of a
decrease of 11,226 barrels (20%) from the properties that the Company owned
during both periods and an increase of 35,774 barrels from the properties
acquired during the period from October 1, 1996 to June 30, 1997. The decrease
in production of crude oil from the properties owned during the comparative
quarters is primarily a reflection of natural depletion of the crude oil
producing reservoirs, and the temporary loss of production from certain
properties due to work overs during the six months ended December 31, 1997.

The Company produced 486,467 Mcf of natural gas during the six months ended
December 31, 1997, an increase of 283,546 Mcf (140%) over the 202,921 Mcf
produced during the comparable period in 1996. This increase was comprised of an
increase of 37,926 Mcf (19%) from the properties the Company owned during both
periods and an increase of 245,620 Mcf from the properties acquired during the
period from October 1, 1996 to September 30, 1997. The increase in production
from the properties owned during the comparative six months is a result of the
successful drilling of four wells and the work over of certain producing and
non-producing wells, off-set by the natural depletion of the natural gas
producing reservoirs.

The average selling price of oil was $18.14 per bbl for the six months ended
December 31, 1997, compared to $22.36 per bbl in the comparable period in 1996.
This decrease of $4.22 per bbl (19%) is a result of general decreases in oil
prices. The average selling price of natural gas was $2.41 per Mcf for the six
months ended December 31, 1997, compared to $2.33 per Mcf in the comparable
period in 1996. This increase of $0.08 per Mcf is a result of general increases
in natural gas prices during the six months ended December 31, 1997.

The Company entered into agreements with Enron Capital & Trade Resources Corp.
("Enron"), an affiliate of Joint Energy Development Investments Limited
Partnership ("JEDI"), the holder of 9.6 million shares of the Company's Series A
Participating Convertible Preferred Stock, to hedge 50,000 MMBtu of natural gas
production and 10,000 barrels of oil production monthly. The agreements, which
are effective September 1, 1997, and terminate August 31, 1998, call for a gas
and oil ceiling and floor price of $2.66 and $1.90 per MMBtu of natural gas and
$20.40 and $18.00 per barrel of crude oil, respectively. If the average market
price of oil and gas per month, as defined in the agreements, exceeds the
ceiling price, the Company must pay Enron an amount equal to one-half of the
amount of the hedged quantities multiplied by the difference between the ceiling
price and the market price. If the average market price, as defined, falls below
the floor price, Enron will pay the Company an amount equal to the amount of the
hedged quantities multiplied by the difference in the floor price and the market
price. Pursuant to these hedging agreements, the Company made cumulative net
payments to Enron of $5,700 and $21,708 as a result of crude oil and natural gas
prices exceeding the ceiling prices in the agreements during the six months
ended December 31, 1997.

PRODUCTION EXPENSES The Company's lease operating expenses ("LOE's") rose to
$1,853,000 for the six months ended December 31, 1997, an increase of $969,000
(109%) from the comparable period in 1996. The increase is a combination of the
117% (based on BOE produced) increase in production offset by a decrease in the
LOE per BOE. The average LOE per BOE was $9.23 per BOE during the six months
ended December 31, 1997, a decrease of $0.36 (4%) over the average LOE per BOE
of $9.59 for the comparable period in 1996. Recurring 

                                       10
<PAGE>   11
LOE's, those costs incurred in the normal operations of the Company, were
$1,447,000 during the six months ended December 31, 1997, or $7.21 per BOE, as
compared to $851,000, or $9.22 per BOE, during the comparable period in 1996.
This represents a $2.01 per BOE (22%) improvement. The Company believes that
this improvement is a result of improved efficiencies at an operating level and
the acquisition of properties with lower average operating costs per BOE than
those the Company has owned during the preceding years. Non-recurring LOE's,
which are work over costs incurred to increase production from existing
producing reservoirs and thus are arguably more capital in nature, but must be
treated as expenses under the Securities and Exchange Commission accounting
rules, were $406,000 $(2.02 per BOE) during the six months ended December 31,
1997, as compared to only $34,000 $(0.37 per BOE) during the comparable period
in 1996. This $372,000 (1,094%) increase in non-recurring LOE's is consistent
with the Company's strategy of redeveloping its properties to increase
production, the objective of which is to increase production and reduce the LOE
per BOE. Early indications are that this program will have the desired effect on
production and LOE's over the long term.

SEVERANCE AND PRODUCTION TAXES Severance and production related taxes were
$221,000 for the six months ended December 31, 1997, compared to $133,000
incurred in the comparable period in 1996. This increase of $88,000 (66%) is a
function of the 117% (based on BOE produced) increase in production offset by
the decrease in oil and natural gas prices (14% based on BOE produced).

DEPRECIATION, DEPLETION AND AMORTIZATION EXPENSE Depreciation depletion, and
amortization (DDA) costs were $871,000 for the six months ended December 31,
1997, an increase of $414,000 (91%) over the $457,000 recognized during the
comparable period in 1996. This increase relates primarily to the 117% increase
in BOE produced. The DDA cost per BOE was $4.34 during the six months ended
December 31, 1997, a decrease of $0.61 per BOE (12%) over the $4.95 per BOE for
the comparable period in 1996. This decrease in DDA per BOE is primarily the
result of a reduction in the expected future capital costs required to bring the
Company's reserves into production.

GENERAL AND ADMINISTRATIVE COSTS The general and administrative costs of the
Company were $1,218,000 during the six months ended December 31, 1997, as
compared to $549,000 for the comparable period in 1996. This increase of
$669,000 (122%) consists of an unusually high, one-time expense of $300,000 for
financial public relations services.. The Company issued 150,000 restricted
shares of its common stock in consideration of these services. After adjusting
for this item, general and administrative expenses rose by $369,000 (67%). On a
cost per BOE produced basis, general and administrative expenses were $6.07 per
BOE, an increase of $0.12 per BOE from the $5.95 per BOE (2%) for the comparable
period in 1996. After adjusting for the unusual item described above, general
and administrative expenses were only $4.58 per BOE.

INTEREST EXPENSE The Company incurred interest charges of $639,000 during the
six months ended December 31, 1997 compared to $404,000 for the comparable
period in 1996. This increase of $236,000 (58%) is a reflection of the increase
in the average interest bearing debt of the Company, from $7.3 million for the
six months ended December 31, 1996 to $13.8 million during the six months ended
December 31, 1997. This increase in the average interest bearing debt of $6.5
million in debt was used primarily to finance the acquisition of more than $9
million of oil and gas producing properties.

LIQUIDITY AND CAPITAL RESOURCES

GENERAL The Company's general financial strategy is to use cash from operations
to service interest on the Company's indebtedness, to pay ongoing operating
expenses, and to contribute limited amounts toward further development of the
Company's existing proved reserves as well as additional acquisitions. There can
be no assurance that cash from operations will be sufficient in the future to
cover all of those purposes.

The Company will continue to be dependent on external funding sources to carry
out its planned redevelopment and acquisition program. If such additional funds
are not available, the Company will be required to delay or reduce substantially
both of such activities.

INDEBTEDNESS

SENIOR CREDIT FACILITY The Company has a secured revolving loan facility (the
"Senior Credit Facility") which provides for borrowings up to $75 million with
the Bank of Montreal, Houston, Texas ("Bank of Montreal") to, among other
things, fund working capital and make additional acquisitions as and if
appropriate opportunities are identified. On January 13, 1998 the Company
received approval from the Bank of Montreal to borrow up to $15,000,000 under
this revolving loan facility of which $5 million was outstanding as of February
13, 1998. The loan under this Senior Credit Facility matures on August 1, 2003.
In the event of a default on the bank indebtedness, not subsequently waived by
the bank, it is unlikely that the Company would be able to continue its
business. In addition, the Company is subject to certain financial and operating
covenants that are usual and customary for transactions of this nature,
including, but not limited to, requirements to provide annual audited and
unaudited interim financial information, prohibitions on additional debt,
restrictions on certain payments and distributions to affiliates and others,
restrictions on changes in the nature of the business, and maintenance of
minimum, cash flow, and operating ratios. The Company was to maintain a minimum
interest coverage ratio and maintain positive working capital, after adding to
the current assets the unutilized portion of the revolving loan. The loan
agreement also contains usual and customary events of default and provides
remedies to the Bank of Montreal in the event of default. Although the Company
believes that its cash flows and available sources of financing will be
sufficient to satisfy the interest payments on its debt at currently prevailing
interest rates and oil and gas prices, the Company's level of debt may adversely
affect the Company's ability: (i) to obtain additional financing for working
capital, capital expenditures or other purposes, should it need to so do; or
(ii) to acquire additional oil and gas properties or to make acquisitions
utilizing new borrowings. There can be no assurances that the Company will be
able to obtain additional financing, if required, or that such financing, if
obtained, will be on terms favorable to the Company.

On September 30, 1997 and December 31, 1997 the Company was not in compliance
with its interest coverage ratio. The Bank of Montreal waived the September 30,
1997 covenant violation solely with respect to these specific defaults. On
February 10, 1998 the Bank of Montreal waived the Company's December 31, 1997
noncompliance with the interest coverage ratio. On the same date the Senior
Credit Facility was amended to reduce the interest coverage ratio to 1.75:1 for
the quarter ending March 31, 1998 and 3.0:1 thereafter. In addition, the Company
and its subsidiaries agreed that during calendar 1998, they would not incur,
without the prior written consent of the Bank of Montreal, in aggregate, capital
expenditures in excess of those disclosed to the Bank of Montreal in the
Company's operating forecast $(2.6 million). The Company believes, but cannot
assure, that it will be able to comply with all restrictive covenants in the
future or obtain waivers from the bank with respect to noncompliance.

From time to time in the future, the Company may submit information to the Bank
of Montreal in accordance with the procedures provided in the loan agreement to
support the Company's request to increase the maximum borrowing base as the
Company believes appropriate. All such applications will be subject to bank
approval. If available, these funds would be allocated toward future development
and acquisition programs.

On January 8, 1998 the Company repaid two notes totaling $2 million. The Company
increased its debt outstanding on the Senior Credit Facility by $2 million to
fund this repayment.

SUBORDINATED CREDIT FACILITY Effective December 29, 1997, the Company
established a Subordinated Revolving Credit Facility (the "Subordinated Credit
Facility") with Enron Capital & Trade Resources Corp. ("Enron"), as a lender and
as agent for the lenders thereto, to fund capital costs incurred with future
development projects and to fund further acquisitions. The Subordinated Credit
Facility is subordinate to the Senior Credit Facility. The Subordinated Credit
Facility provides for borrowings up to $10.0 million, subject to borrowing base
limitations, which has been initially set at an amount equal to forty percent
(40%) of the borrowing base established from time to time under the Senior
Credit Facility. This facility is intended to provide bridge financing for
development projects and acquisitions to be completed on relatively short notice
or until the affected assets are eligible to be included in the borrowing base
for the Senior Credit Facility or financed with longer-term indebtedness or
equity capital; provided, that the availability for acquisitions under the
facility is limited to the lesser of $5,000,000 or the borrowing base as in
effect from time to time. The Company may currently borrow up 

                                       12
<PAGE>   13
to $6,000,000 under the Subordinated Credit Facility. The Company has not
borrowed any money as of February 13, 1998 under this facility. Borrowings in
excess of certain amounts under the Subordinated Credit Facility will reduce the
available borrowing base under the Senior Credit Facility. The loan is secured
by a second priority lien and security interest (behind the first lien position
of the Senior Credit Facility) in approximately eighty-five percent (85%) of the
oil and gas properties of the Company.

The Subordinated Credit Facility is subject to payment of interest at a
fluctuating rate per annum equal to (i) the rate of one percent (1%) above the
then highest rate of interest being paid on any portion of the indebtedness owed
under the Senior Credit Facility or (ii) the rate of fifteen percent (15%),
depending upon whether there is any indebtedness owed under the Senior Credit
Facility outstanding or whether there has been a certain amount of indebtedness
owed to Enron for certain time periods

The maturity date for the Subordinated Credit Facility is the earlier of
December 30, 2002 or the date that is 60 days after the Company receives written
notice that the lenders and their affiliates beneficially own in the aggregate
less than ten percent (10%) of the capital stock of the Company entitled to vote
in the election of directors. From March 31, 1998 through the maturity date, the
Company will pay interest on the outstanding loans at quarterly intervals, on
the last business day of every March, June, September and December. In addition,
the Subordinated Credit Facility provides for certain voluntary prepayments and
certain mandatory prepayments of amounts borrowed under the facility.

The Company paid an affiliate of Enron a fee of $200,000 in connection with the
arrangement of the Subordinated Credit Facility. In addition, commencing March
31, 1998, and on each payment date thereafter, the Company is obligated to pay
Enron, for the account of each lender under the Subordinated Credit Facility, a
fee of 3/8% per annum on the daily average of the unadvanced portion of the
facility for the period since January 12, 1998 or the previous payment date to
such payment date.

The Company is subject to various covenants under the Subordinated Credit
Facility, which covenants are substantially similar to the covenants described
above with respect to the Senior Credit Facility. In addition to the covenants,
the Subordinated Credit Facility contains representations, warranties, covenants
and default provisions customary for a facility of this type.

REGULATION S BOND Through February 13, 1998 the Company was engaged in the
distribution in Europe of Deutschemark denominated (DEM) 12% Bonds ("12% Bonds")
totaling DEM 3.95 million $(2.2 million). Under Regulation S of the Securities
Act, the Company is prohibited from selling these Bonds to U.S. persons (as
defined in Regulation S). The Company has discontinued its efforts to sell any
additional 12% Bonds.

The Company is obligated to make periodic interest payments (January 15 and July
15 of each year) and to repay the principal when it comes due on July 15, 2000
in DEM. All interest payments have been paid in full at the time they came due.
The funds generated by the Company from operations, which form the primary
source of funds to pay the interest, are denominated in $US. The source of funds
required to repay the principal outstanding on these bonds has not yet been
identified, since the bonds do not mature until July 15, 2000. The Company is
exposed to the risk that, upon repayment, the exchange rate between DEM and $US
may be less favorable than that which existed at the time that the bonds were
issued. This would result in the Company having to repay a larger number of $US
than it received initially. Changes in the $US equivalent of the DEM bonds
arising from changes to the DEM:$US exchange rate are recognized monthly. At
December 31, 1997 the Company had recorded unrealized exchange rate gains of
approximately $361,000 (at June 30, 1997 $300,000). However, there are no
assurances that the Company will continue to realize gains related to favorable
changes in the DEM:$US exchange rates in the future. Unfavorable changes to the
DEM:$US exchange rate will result in the Company recording unrealized exchange
rate losses related to the changes as they occur. The Company believes it has
the opportunity to enter into arrangements to manage its DEM:$US exchange rate
risk. At this time, the Company has not entered into any such arrangements.


                                       13
<PAGE>   14
SUBORDINATED NOTES TO SELLERS Pursuant to the Frymire Purchase in November 1996,
the Company issued three notes to the seller. The first two notes plus accrued
interest were retired on their respective due dates. The third note, initially
in the amount of $227,500, is payable monthly with principal and interest
amortized over two years, bearing interest at ten percent (10%). All payments
relating to the third note have been made as they came due. The principal
outstanding on this note, at February 13, 1998 approximated $55,300 (at December
31, 1997 $75,504). This note is fully subordinated to the Senior Credit
Facility. The Company has and continues to intend to use funds from operations
to retire the remainder of this note and related interest. There can be no
assurances that the Company can generate the funds to redeem the note and
related interest that matures on July 1, 1998.

REGULATION D SHARES The Company issued 150,000 shares of Common Stock pursuant
to Regulation D in December 1997, in consideration for services rendered, which
it valued at $2.00 per share $(300,000) for purposes of this transaction. In
December 1997 the Company issued 10,000 shares of Series "C" preferred stock for
$10,000,000, and 400 shares of Series "C" preferred stock as partial
consideration for services rendered in the placement of this Series "C"
preferred stock. The aggregate liquidation preference is $10,400,000. This
Series "C" preferred stock is convertible into the Common Stock of the Company
on the basis of a formula that is a function of the market price of the Common
Stock at the time of the conversion (See "Part II, Item 2"). With the issuance
of the Series "C" preferred stock, both the Bank of Montreal and Joint Energy
Development Investments Limited Partnership have acknowledged that the Company's
covenants to each of them to raise $5.4 million of net cash equity by December
31, 1997 from the issuance of Common Stock of the Company have been met.

REGULATION S SHARES In January 1998 the Company issued 200,000 shares of its
common stock to a "non-U.S. person" pursuant to the exercise of 200,000 Class A
Warrants for $2.50 per share $(500,000).

WARRANTS In December 1997 the Company issued 340,138 warrants in conjunction
with the issuance of the Series "C" preferred stock. These warrants are
exercisable at a strike price on the basis of a formula that is a function of
the market price of the Common Stock at the time of exercise of the warrants.
These warrants may be exercised commencing December 24, 1997 and ending on
December 24, 2001 (See Part II, Item 2).

In February 1998 the Company issued 1,145,134 warrants ("maintenance warrants")
to JEDI pursuant to a Securities Purchase Agreement dated March 27, 1997. A
total of 1,554,973 maintenance warrants have been issued to JEDI. These
maintenance warrants are exercisable at strike prices ranging from $1.85 to
$3.50 per common share for total proceeds of approximately $4 million. All of
the maintenance warrants are currently exercisable and expire at various times
prior to December 31, 1998.

In addition, there are 1,800,000 Class A warrants and 1,000,000 Class B warrants
outstanding. These "A" and "B" warrants can be exercised at a strike price of
$2.50 per common share and expire on December 31, 1998.

EXCHANGE RIGHTS The Subordinated Credit Facility provides that, commencing
January 1999, during certain periods, any indebtedness of Queen Sand Resources,
Inc., a Nevada corporation and a wholly-owned subsidiary of the Company, may be
exchanged by the lenders for shares of the Company's Common Stock. The exchange
ratio is based on a formula that is a function of the market price of the Common
Stock at the time of exchange (See "Part II, Item 2").

OTHER SOURCES The Company does not have sufficient liquidity or capital to
undertake all potential acquisition prospects or to fund fully the development
of any prospect. Therefore, the Company will continue to be dependent on raising
substantial amounts of additional capital through any one or a combination of
institutional or bank debt financing, equity offerings, debt offerings and
internally generated cash flow, or by forming sharing arrangements with industry
participants. Although the Company has been able to obtain such financings and
to enter into such sharing arrangements in certain of its projects to date,
there can be no assurance that it will continue to be able to do so.
Alternatively, the Company may consider issuing additional securities in
exchange for producing properties. There can be no assurance that any such
financings or sharing arrangement can be obtained. Therefore, notwithstanding
the Company's need for substantial amounts of additional capital, there can be
no assurance that it can be obtained.

Further acquisitions and development activities in addition to those for which
the Company is contractually obligated are discretionary and depend exclusively
on cash availability from outside sources such as bank debt and the sale of
securities or properties.

YEAR 2000 COMPUTER ISSUE The Company has reviewed its computer systems in order
to evaluate necessary modifications for the year 2000. The Company does not
currently anticipate that it will incur material expenditures to complete any
such modifications.

ITEM 2.    CHANGES IN SECURITIES

ISSUANCE OF SERIES C PREFERRED STOCK AND WARRANTS On December 24, 1997, in
reliance on Section 4(2) of the Securities Act of 1933, as amended (the
"Securities Act"), and on Regulation D promulgated pursuant to the Securities
Act, the Company issued 10,000 shares of Series C Convertible Preferred Stock,
par value $0.01 per share, of the Company (the "Series C Preferred Stock") to
certain institutional investors (collectively, the "Purchasers") and warrants to
purchase an aggregate of 340,138 shares of the Company's Common Stock (the
"Warrants") to the Purchasers in exchange for aggregate cash consideration of
$10,000,000. In addition, in reliance on Section 4(2) of the Securities Act, and
on Regulation D promulgated pursuant to the Securities Act, the Company issued
400 shares of Series C Preferred Stock to Palisades Holdings, Inc. in exchange
for its services as the placement agent for the transaction. The Warrants may be
exercised in full or in part by means of payment of the exercise price which is
equal to a fixed conversion price in effect on the exercise date; provided,
however, that if the ADTV (as defined in the Certificate of Designation of the
Series C Preferred Stock (the "Series C Certificate of Designation")) for the
Common Stock during the period of six (6) months following the closing date is
less than five hundred and forty thousand dollars $(540,000), the exercise price
shall be the lesser of (i) the fixed conversion price and (ii) the average of
the closing bid prices (as defined in the Series C Certificate of Designation)
for the Common Stock during the twenty-two (22) trading days occurring prior to
the last day of such six-month period.

DESCRIPTION OF SERIES C PREFERRED STOCK The Series C Certificate of Designation
authorizes the issuance of up to 10,400 shares of Series C Preferred Stock. The
following description of the rights, preferences and limitations of the Series C
Preferred Stock is a summary only and is qualified in its entirety by reference
to the entire text of the Series C Certificate of Designation which is an
exhibit to a Current Report on Form 8-K dated December 24, 1997 filed by the
Company with the Securities and Exchange Commission.

Voting The holders of shares of Series C Preferred Stock are not entitled to
vote with the holders of the Company's Common Stock except as required by law or
as set forth below.

For so long as any shares of Series C Preferred Stock are outstanding, the
following matters will require the approval of the holders of at least
two-thirds of the then outstanding shares of Series C Preferred Stock, voting
together as a separate class:

         (i)      alter or change the rights, preferences or privileges of the
                  Series C Preferred Stock or any other capital stock of the
                  Company so as to affect adversely the Series C Preferred
                  Stock;

         (ii)     create any new class or series of capital stock having a
                  preference over or ranking pari passu with the Series C
                  Preferred Stock as to redemption, the payment of dividends or
                  distribution of assets upon a Liquidation Event (as defined in
                  the Series C Certificate of Designation) or any other
                  liquidation, dissolution or winding up of the Company;

         (iii)    increase the authorized number of shares of preferred stock of
                  the Company;

                                       15
<PAGE>   16
         (iv)     re-issue any shares of Series C Preferred Stock which have
                  been converted in accordance with the terms hereof;

         (v)      issue any Senior Securities (other than the Company's Series B
                  Participating Convertible Preferred Stock pursuant to the
                  terms of the Company's Series A Participating Convertible
                  Preferred Stock) or Pari Passu Securities (each, as defined in
                  the Series C Certificate of Designation); or

         (vi)     declare, pay or make any provision for any dividend or
                  distribution with respect to the Common Stock or any other
                  capital stock of the Company ranking junior to the Series C
                  Preferred Stock as to dividends or as to the distribution of
                  assets upon liquidation, dissolution or winding up of the
                  Company.

In the event that the holders of at least two-thirds (2/3) of the then
outstanding shares of Series C Preferred Stock agree to allow the Company to
alter or change the rights, preferences or privileges of the shares of Series C
Preferred Stock pursuant to the terms hereof, or to waive any rights of the
holders hereunder, then the Company will deliver notice of such approved change
to the holders of the Series C Preferred Stock that did not agree to such
alteration or change (the "Dissenting Holders") and the Dissenting Holders shall
have the right for a period of thirty (30) days following such delivery to
convert their Series C Preferred Stock pursuant to the terms hereof as they
existed prior to such alteration or change, or to continue to hold such shares.
No such change shall be effective to the extent that, by its terms, it applies
to less than all of the holders of Series C Preferred Stock then outstanding.

Conversion Subject to certain limitations set forth in the Series C Certificate
of Designation, a holder of shares of Series C Preferred Stock has the right, at
the holder's option, to convert all or a portion of its shares into shares of
Common Stock at any time. The number of shares of Common Stock into which a
share of Series C Preferred Stock may be converted will be determined as of the
conversion date according to a formula set forth in the Series C Certificate of
Designation. If the Company fails to deliver shares of Common Stock to a holder
following a conversion in accordance with the Series C Certificate of
Designation, then the Company will be liable to the holder for certain cash
default payments set forth in the Series C Certificate of Designation.

On December 24, 2001, all shares of Series C Preferred Stock that are then
outstanding shall be automatically converted into the number of shares of Common
Stock determined in accordance with the formula set forth in the Series C
Certificate of Designation.

The Series C Certificate of Designation provides for customary adjustments to
the number of shares issuable upon conversion in the event of certain dividends
and distributions to holders of Common Stock, certain reclassifications of the
Common Stock, stock splits, combinations and mergers and similar transactions
and certain changes of control.

Dividends The holders of the shares of Series C Preferred Stock are entitled to
receive dividends, when, and as if declared by the Board of Directors, out of
funds legally available therefor, subject to the prior payment of any
accumulated and unpaid dividends to holders of Senior Securities, but before
payment of dividends to holders of Junior Securities (as defined in the Series C
Certificate of Designation), cumulative dividends on each of the Series C
Preferred Stock shares in an amount equal to the stated value of such share
multiplied by five percent (5%).

Liquidation Upon the liquidation, dissolution or winding up of the Company, the
holders of the shares of Series C Preferred Stock, before any distribution to
the holders of Junior Securities, and after payment to holders of Senior
Securities, will be entitled to receive an amount equal to the stated value of
the Series C Preferred Stock (subject to ratable adjustment in the event of
reclassification of the Series C Preferred Stock or other similar event) plus
any accrued and unpaid dividends thereon ("Liquidation Preference").

Optional Redemption The Company has the right to redeem all of the outstanding
Series C Preferred Stock at a price equal to the Liquidation Preference of the
Series C Preferred Stock then held by the holder divided by eighty percent (80%)
("Optional Redemption Price"), to the extent permitted by law and so long as (i)
the Company has 

                                       16
<PAGE>   17
sufficient cash available at the time; (ii) the Company delivers prior written
notice at least thirty trading days prior to the redemption, specifying both the
date of the redemption and the amount payable to the holder; and (iii) the
Common Stock is actively traded on the NASDAQ Stock Market, the New York Stock
Exchange or the American Stock Exchange.

Mandatory Redemption The Series C Certificate of Designation provides for
mandatory redemption by the Company when a Mandatory Redemption Event occurs (as
defined in the Series C Preferred Stock Certificate of Designation).

Upon the occurrence of a Mandatory Redemption Event, each holder of Series C
Preferred Stock will have the right to require the Company to redeem its Series
C Preferred Stock at a redemption price equal to the greater of (i) the
Liquidation Preference of the Series C Preferred Stock being redeemed multiplied
by one hundred and twenty five percent (125%) and (ii) an amount determined by
dividing the Liquidation Preference of the Series C Preferred Stock being
redeemed by the conversion price in effect on the mandatory redemption dated and
multiplying the resulting quotient by the average closing bid price for the
Common Stock on the five (5) trading days preceding the mandatory redemption
date ("Mandatory Redemption Price").

If the Mandatory Redemption Price is not paid within five business days of the
redemption date and the holder has tendered its Series C Preferred Stock to the
Company, the holder is entitled to interest thereon, from the redemption date
until the Mandatory Redemption Price has been paid in full.

If the Mandatory Redemption Price is not paid within ten business days of the
redemption date, each holder of shares of Series C Preferred Stock will have the
right, by written notice to the Company, to require the Company to issue, in
lieu of the Mandatory Redemption Price, the number of shares of Common Stock of
the Company equal to the Mandatory Redemption Price divided by the conversion
price in effect on such conversion date as specified by the holder, with the
conversion price to be reduced by one percent (1%) for each day beyond the 10th
business day in which the Company fails to pay the Mandatory Redemption Price,
but with the maximum reduction of the conversion price to be fifty percent
(50%).

ISSUANCE OF EXCHANGEABLE NOTE Effective December 29, 1997, Queen Sand Resources,
Inc., a Nevada corporation and wholly-owned subsidiary of the Company, entered
into the Subordinated Credit Facility with Enron. The Subordinated Credit
Facility provides that commencing January 1, 1999, during certain periods under
the facility, the lenders may exchange any debt outstanding under the facility
into the Company's Common Stock. The exchangeable debt was issued in reliance on
Section 4(2) of the Securities Act. The exchange ratio is based on a formula
that is a function of the market price of the Common Stock at the time of the
exchange.

Securities Act, the Company issued 150,000 shares of Common Stock in December
1997 to a consulting firm as partial consideration for services rendered, which

Agreement, each Lender agrees to make Loans to the Borrower on any Business Day
during the period from the date hereof until the Maturity Date, in such amounts

outstanding amount not to exceed the lesser of (a) such Lender's Maximum



                                      -13-
<PAGE>   19



Commitment and (b) such Lender's Pro Rata Share of the Borrowing Base. The
Borrower may make prepayments as permitted or required in Sections 2.9 and 2.10
and reborrowings in respect thereof; provided, however, that the aggregate
principal amount of all such Loans at any one time outstanding shall not exceed
the aggregate amount of the Lenders' Commitments; and provided further, that no

aggregate amount of the Lenders' Commitments is less than $100,000, in which
event the Borrowing may be for such available amount. The Loans made by the
Lenders to the Borrower pursuant to this Agreement shall be evidenced by the
Notes.

of Borrowings made hereunder solely for the following purposes:

                  (a) Capital Costs. To pay the Capital Costs incurred in
connection with any proposed Development Projects.

                  (b) Acquisitions. To fund the cost of Acquisitions by the
Borrower.

         Section 2.3       Funding of Capital Costs and Acquisitions.

                  (a) No Loans for the costs incurred by the Borrower for any
Development Project (Borrower's share of such costs being referred to herein as
the "Capital Costs") shall be made by the Lenders unless the Borrower shall have
submitted a Project Summary or Plan of Development for such project to the Agent
in advance.

                  (b) No Lender shall have any obligation to provide any Loan
which will be used to fund an Acquisition, if the making of such Loan would
cause the aggregate outstanding amount of Loans made by such Lender used to fund
Acquisitions to exceed the lesser of (I) such Lender's Pro Rata Share of
$5,000,000 or (II) such Lender's Pro Rata Share of 50% of the Borrowing Base.

         Section 2.4       Borrowing Base.

                  (a) So long as the Bank of Montreal remains the agent under
the Senior Loan Agreement and there is no change of control (as used in the
definition of "Affiliate") in the Bank of Montreal, or until such time as the
Agent determines (with the concurrence of the Majority Lenders) in its sole
discretion, that the Senior Loan Borrowing Base is not the amount that the Agent
would have established as the Senior Loan Borrowing Base if the Agent were the
"Agent" under the Senior Loan Agreement, the Borrowing Base shall be an amount
equal to forty percent (40%) of the Senior Loan Borrowing Base and shall change
as and when Senior Loan Borrowing Base changes. Should the Bank of Montreal
cease to be the agent under the Senior Loan Agreement or there is a change of
control (as used in the definition of "Affiliate") in the Bank of Montreal, or
the Agent determines (with the concurrence of the Majority Lenders), in its sole
discretion, that the Senior Loan Borrowing Base is not the amount that the Agent
would have established as the Senior Loan Borrowing Base if the Agent were the
"Agent" under the Senior Loan Agreement, the Borrowing



                                      -14-
<PAGE>   20



Base shall thereafter be determined in accordance with Section 2.4(b) by the
Agent (with the concurrence of the Majority Lenders) and shall be subject to
redetermination in accordance with Section 2.4(c). Without limiting the Agent's
discretion to make redeterminations of the Borrowing Base for other reasons, the
Borrower acknowledges that upon any amendment or other modification to the terms
of the Senior Debt, the Agent (with the consent of the Majority Lenders) may
redetermine the Borrowing Base in accordance with Section 2.4(b). Upon any
redetermination of the Borrowing Base by the Agent, such redetermination shall
remain in effect until the next successive Redetermination Date.

                  (b) In the event any of the conditions set forth in the second
sentence of Section 2.4(a) should occur, the Agent shall give written notice
thereof to the Borrower and the Borrowing Base shall thereafter be determined as
provided in this Section 2.4(b). Upon receipt of the most recent Reserve Reports
and accompanying production reports required to be delivered pursuant to Section
4.7 and such other reports, data and supplemental information as may from time
to time be reasonably required by the Agent, including Plans of Development, the
Agent will evaluate the Reserve Reports and such other reports, data and
supplemental information and redetermine the Borrowing Base. Each
redetermination of the Borrowing Base will be made in good faith in accordance
with the Agent's normal and customary procedures for evaluating oil and gas
reserves and other related assets and information as such exist at that
particular time. The Agent, in its sole discretion, may make adjustments to the
rates, volumes and prices and other assumptions set forth in the Reserve Reports
and such other reports, data and supplemental information provided to the Agent.
The Borrower acknowledges that, in determining the Borrowing Base, (i) the Agent
may utilize any prices established in any relevant price risk management
agreements of the Borrower, and that prices used by the Agent for any non-hedged
reserve production may not necessarily reflect the then market price for such
Hydrocarbons and (ii) the quantity and terms of the Senior Debt shall be a
factor in any such determination. The Agent may exclude any Oil and Gas Property
or portion of production therefrom or any income from any other Property from
the Borrowing Base, at any time, because title information is not reasonable
satisfactory or such Property is not Mortgaged Property.

                  (c) So long as the Commitment is in effect and until payment
in full of all Loans hereunder, on or around the 15th Business Day of each March
and September, commencing March 15, 1998 (each being a "Scheduled
Redetermination Date"), the Agent shall redetermine the amount of the Borrowing
Base in accordance with Sections 2.4(a) or 2.4(b), as applicable. After the
March 15, 1998, Scheduled Redetermination Date, the Majority Lenders may
initiate a redetermination of the Borrowing Base by the Agent at the Borrower's
expense at any time as the Majority Lenders may require including without
limitation at any time that the Borrower materially changes the completion date
of any Development Project, fails to fund any shortfall in Capital Costs as
required pursuant to Section 2.7(d) or the Majority Lenders believe events or
conditions have occurred which would decrease the then current Borrowing Base by
ten percent (10%) or more.

                  (d) In connection with any redetermination of the Borrowing
Base pursuant to 2.4(b) or 2.4(c), the Agent shall propose to the Lenders a new
Borrowing Base by no later than the



                                      -15-
<PAGE>   21



earlier of (i) 30 days following receipt by the Agent of the Reserve Reports to
be used in connection with such redetermination or (ii) 10 days prior to the
next Scheduled Redetermination Date, in each case assuming receipt of the
Reserve Reports in a timely and complete manner. After having received notice of
such proposal by the Agent, the Lenders shall have 10 days to agree or disagree
with such proposal. If at the end of such 10 days, the Majority Lenders have not
communicated their approval or disapproval, such silence shall be deemed to be
an approval and the Agent's proposal shall be the new Borrowing Base. If
however, the Majority Lenders notify Agent within 10 days of their disapproval,
the Borrowing Base shall be set at the lower of the Agent's proposal or the
amount of the then current Borrowing Base; and the Borrowing Base shall remain
at such level until the Majority Lenders agree on a new Borrowing Base.

                  (e) The Agent shall promptly notify the Borrower of any
redetermination of the Borrowing Base. Any redetermination of the Borrowing Base
and any changes in the amounts available for Capital Costs or for Acquisitions
resulting from such redetermination shall not be in effect until written notice
is received by the Borrower.

         Section 2.5       Interest.

                  (a) The outstanding principal amount of the Loans made
pursuant to the Notes and this Agreement shall bear interest from the date made
until due at a fluctuating interest rate per annum that is equal to the lesser
of the Highest Lawful Rate or the following:

                           (i) Except as provided in subsection (ii) below, the
         rate of one percent (1%) above the then highest rate of interest being
         paid on any portion of the Senior Debt; provided that if no Senior Debt
         is outstanding, the rate of fifteen percent (15%).

                           (ii) If the aggregate outstanding principal balance
         of the Loans exceeds $2,000,000 during each day of any continuous
         period of 120 days, the outstanding principal amount of the Loans shall
         bear interest at the rate equal to the greater of (I) the rate provided
         in subparagraph (i) of this section or (II) fifteen percent (15%). Such
         rate change shall be effective as of the first day following such 120
         day period and shall remain in effect until the first day on which the
         aggregate outstanding principal balance of the Loans has not exceeded
         $2,000,000 at any time during the thirty (30) day period immediately
         preceding such day.

                  (b) Past due interest, principal and other amounts hereunder
shall bear interest at a fluctuating interest rate per annum that is equal to
the lesser of (i) eighteen percent (18%) per annum or (ii) the Highest Lawful
Rate from the date due until paid ("Default Rate").

                  (c) Each change in the fluctuating interest rate set forth in
subsection 2.5(a)(i) shall be effective simultaneously with the corresponding
change in the rate of interest being paid on the Senior Debt. Interest shall be
computed (i) for payments of interest based upon the Senior Debt, on the per
annum basis provided for in the Senior Loan Agreement and (ii) for all other
payments of interest under the Loan Documents, on the per annum basis of a year
of 365 or 366 days, as the



                                      -16-
<PAGE>   22



case may be, and for the actual number of days (including the first day but
excluding the last day) elapsed.

                  (d) Within two (2) Business Days after the last day of each
month, the Borrower shall provide the Agent with a certificate (certified by the
chief financial officer of the Borrower) detailing the highest rate of interest
paid on account of the Senior Debt for each day of such month.

         Section 2.6       Fees.

                  (a) Upon execution of this Agreement, the Borrower shall pay
the fees described in the Fee Letter.

                  (b) Commencing March 31, 1998, and on each Payment Date
thereafter, the Borrower agrees to pay to the Agent for the account of each
Lender a facility fee ("Facility Fee") of three-eights of one percent (3/8%) per
annum on the daily average of the unadvanced portion of such Lender's Commitment
for the period since January 12, 1998, or the previous Payment Date, as the case
may be, to such Payment Date.

         Section 2.7       Notice and Manner of Borrowing.

                  (a) The amount and date of each Borrowing shall be designated
by the Borrower's execution of a Borrowing Request, accompanied by the
documentation required in Sections 2.7(b) and (c), to be received by the Agent
at least five (5) Business Days prior to the requested date of such Loan, which
date must be a Business Date, except for the initial Loan which may be requested
on the date of this Agreement. The Agent shall give to each Lender prompt notice
of such proposed Borrowing by telecopy or telex. Each Lender shall, before 12:00
p.m. (New York, New York time) on the date of such Borrowing, make available to
the Agent at the Agent's Account, in same day funds, such Lender's Pro Rata
Share of such Borrowing. After the Agent's receipt of such funds and upon
fulfillment of the applicable conditions set forth in Article 7, the Agent will
make such funds available to the Borrower at such account as the Borrower shall
designate to the Agent in writing.

                  (b) Except as provided in Section 2.7(c), in connection with
each Borrowing Request, the Borrower shall deliver a project/acquisition summary
description ("Project Summary") in form and substance reasonably satisfactory to
the Agent describing the Acquisition or Development Project for which the
proceeds of the requested Borrowing shall be used. Each Project Summary shall
contain (i) in the case of Acquisitions, a description of the Oil and Gas
Properties being purchased, the total consideration for such Acquisition, and
the sources of funds to be used in connection therewith, (ii) in the case of
Development Projects, an estimate of the Capital Costs of such Development
Project, and (iii) such other information and documentation as the Agent may
reasonably request.

                  (c) During any Approval Period, (i) the Lenders shall not be
required to fund any Borrowing for an Acquisition unless the Agent (with the
consent of the Majority Lenders) shall have



                                      -17-
<PAGE>   23



approved such Acquisition in its sole discretion, (ii) the Lenders shall not be
required to fund any Borrowing for Capital Costs until the Borrower shall have
submitted and the Agent (with the consent of the Majority Lenders) shall have
approved in its sole discretion a Plan of Development for the applicable
Development Project in advance and (iii) each Borrowing Request for Capital
Costs shall be accompanied by an AFE and an AFE Expenditures Report for all
Capital Costs to be advanced pursuant to the requested Loan.

                  (d) The Borrower covenants and agrees that the Borrower shall
fund any and all Capital Costs for any Development Project that exceed the
amounts advanced pursuant to any Borrowing Request and all Capital Costs which
in the aggregate with all other Loans hereunder would exceed the Commitments of
the Lenders, necessary to complete any proposed Development Project, and that
the Lenders' obligation to fund any Capital Costs is subject to the Agent's
satisfaction that the Borrower has sufficient funds available to fund such
excess.

                  (e) Unless the Agent shall have received notice from a Lender
before the date of any Borrowing that such Lender will not make available to the
Agent such Lender's Pro Rata Share of such Borrowing, the Agent may assume that
such Lender has made its Pro Rata Share of such Borrowing available to the Agent
on the date of such Borrowing in accordance with this Section 2.7, and the Agent
may, in reliance upon such assumption, make available to the Borrower on such
date a corresponding amount. If and to the extent that such Lender shall not
have so made its Pro Rata Share of such Borrowing available to the Agent, such
Lender and the Borrower severally agree to immediately repay to the Agent on
demand such corresponding amount, together with interest on such amount, for
each day from the date such amount is made available to the Borrower until the
date such amount is repaid to the Agent at (i) in the case of the Borrower, the
interest rate applicable on such day to Loans comprising such Borrowing and (ii)
in the case of such Lender, the Federal Funds Rate for such day. If such Lender
shall repay to the Agent such corresponding amount and interest as provided
above, such corresponding amount so repaid shall constitute such Lender's Loan
as part of such Borrowing for purposes of this Agreement even though not made on
the same day as the other Loans comprising such Borrowing. The failure of any
Lender to make the Loan to be made by it as part of any Borrowing shall not
relieve any other Lender of its obligation, if any, to make its Loan on the date
of such Borrowing. No Lender shall be responsible for the failure of any other
Lender to make the Loan to be made by such other Lender on the date of any
Borrowing.

         Section 2.8 Notes. To evidence the Loans made by each Lender pursuant
to this Agreement, the Borrower will issue, execute and deliver to each Lender a
Note in the principal amount of such Lender's Maximum Commitment, each dated as
of the date of this Agreement. Each time a Loan is made hereunder or payment
(including, without limitation, prepayments) is made on the Note, each Lender is
hereby irrevocably authorized by the Borrower to make an appropriate notation on
a ledger forming a part of its Note reflecting the amount loaned or paid and the
date thereof; provided however, the failure of any Lender to do so shall not
relieve the Borrower or any other liable party of its liability hereunder or
under the Note or subject the Borrower or any other liable party to additional
liability under the Note. Furthermore, each Lender is hereby irrevocably
authorized by the Borrower to attach to and to make a part of its Note a
continuation of any such



                                      -18-
<PAGE>   24



schedule of Loans and payments, as and when required, reflecting the amount paid
and the date of such payment. The aggregate unpaid amount of Loans reflected by
the notations by any Lender or the Agent on the records or a ledger sheet or
sheets affixed to the Note shall be deemed rebuttably presumptive evidence of
the principal amount owing on such Lender's Note. Interest provided for in this
Agreement and in the Notes shall be calculated on the unpaid sums actually
loaned and outstanding pursuant to the terms of this Agreement and only for the
period from the date or dates advanced until repaid. The liability for payment
of principal and interest evidenced by the Notes shall be limited to the
principal amounts actually loaned and outstanding pursuant to this Agreement and
interest on such amounts calculated in accordance with this Agreement.

         Section 2.9 Voluntary Prepayments. The Borrower may at its option
prepay the principal amount of the Notes outstanding hereunder on any Business
Day in whole or from time to time in part (but no voluntary partial prepayment
shall be less than $100,000, provided that no voluntary prepayment shall be made
if after giving effect to such prepayment the aggregate outstanding principal
amount under the Note would be less than $100,000) without premium or penalty,
upon giving the Agent at least three (3) Business Days' prior written notice of
the aggregate principal amount to be prepaid, and in the event of any such
notice being given, the amount so notified shall be due and payable on the day
so notified, together with accrued interest thereon to the date of prepayment.
The Borrower shall not have any right to voluntarily prepay amounts owing under
the Notes other than those specifically provided in this Section 2.9.

         Section 2.10 Mandatory Prepayments. Upon any redetermination of the
amount of the Borrowing Base in accordance with Section 2.4, (i) if the
aggregate outstanding principal amount of the Loans exceeds the redetermined
Borrowing Base or (ii) the aggregate outstanding amount of Loans used for
Acquisitions exceeds the lesser of (I) $5,000,000 or (II) 50% of the
redetermined Borrowing Base, then the Borrower shall within thirty (30) days of
receipt of written notice thereof, either (A) prepay the Loans in an aggregate
principal amount equal to such excess, together with accrued interest thereon to
the date of prepayment, or (B) in the Majority Lenders' discretion, subject to a
Security Instrument satisfactory to the Agent, additional Property of the
Borrower satisfactory to the Agent having a loan value (determined by the Agent
in good faith in accordance with Section 2.4(b)) in an amount such that the sum
of such loan value amount plus the aggregate principal amount of prepayments
made pursuant to this Section 2.10 in respect of such Borrowing Base deficiency
equals or exceeds the amount of such Borrowing Base deficiency, and deliver to
the Agent such additional reports, information, and financing statements
covering all of such additional Property as the Agent may reasonably request,
and other legal opinions in form, scope and substance reasonably acceptable to
the Agent opining favorably as to, among such other matters as may be required
by the Agent, (x) the Borrower's ownership of such additional Property, and (y)
the existence of a Lien and security interest on such additional Property,
subject only to Excepted Liens, in favor of the Agent for the benefit of the
Lenders, securing the Indebtedness. Prepayments required under this Section 2.10
shall be without premium or penalty.

         Section 2.11      Exchange of Indebtedness.

                  (a) Beginning January 14, 1999, during any Approval Period, by
written notice (the "Exchange Notice") to the Borrower, the Lenders shall have
the right, at their option (any election to exercise such option shall require
the consent of each Lender), to acquire shares of the Parent Company Common
Stock (as defined below) by (i) exchanging all or any portion of the outstanding
principal balance of the Borrowings and accrued but unpaid interest thereon (the
"Exchange Amount") for that number of fully-paid and nonassessable shares
(calculated as to such exchange to the nearest 1/100th of a share) of the common
stock of the Parent Company ("Parent Company Common Stock") obtained by dividing
(A) the principal amount of the Borrowings and accrued but unpaid interest
thereon to be converted as specified in the Exchange Notice (the "Exchange
Amount") by (B) the Exchange Price (as defined below), determined in accordance
with paragraph (b) below and (ii) if required by applicable law, paying to the
Parent Company, in cash, the aggregate par value of the Parent Company Common
Stock to be issued in accordance with clause (i) above (such payment to be due
upon the receipt by the Lenders of such Parent Company Common Stock). Such
exchange shall be deemed to have been made 30 days after Borrower's receipt of
the Exchange Notice (the Exchange Date") unless the Borrower shall have paid to
the Agent for the account of the Lenders the entire Exchange Amount prior to the
Exchange Date, in which case there shall be no exchange of the Exchange Amount.
Any exchange made hereunder shall be deemed to have been made at the close of
business on the Exchange Date, so that each Lender shall be treated for all
purposes as having become the record holder of its Pro Rata Share of such shares
of Parent Company Common Stock at and as of such time and a payment of the
Exchange Amount on account of the Indebtedness shall be deemed to have occurred
at such time.

                  (b) The "Exchange Price" shall be the product of (i) the
Average Closing Price (as defined below) as of the Exchange Date and (ii) (A) if
the Average Closing Price as of the Exchange Date is less than or equal to the
Average Closing Price as of the date of this Agreement, 0.95 or (B) if the
Average Closing Price as of the Exchange Date is greater than the Average
Closing Price as of the date of this Agreement, 0.85. The "Average Closing
Price" as of any given date shall be the average (arithmetic mean) of the prices
at which of the Parent Company Common Stock is last sold on the NASDAQ National
Market (if the Parent Company Common Stock is listed thereon) or the NASDAQ
SmallCap Market for the 21 consecutive trading days prior to such date. In the
event that the Parent Company Common Stock is not listed on either the NASDAQ
National Market or the NASDAQ SmallCap Market at the time of a exchange pursuant
to this Section 2.11, then the Average Closing Price shall be determined using
the last reported sale prices of the Parent Company Common Stock on the
principal market for the Parent Company Common Stock. If no such principal
market exists, the Average Closing Price shall be the per share value of the
Parent Company Common Stock determined in good faith by the Board of Directors
of the Parent Company. In calculating the Average Closing Price, an appropriate
adjustment shall be made for any stock split (including a reverse split) of the
Parent Company Common Stock or any dividend paid in shares of Parent Company
Common Stock that occurs during the 21 trading day period prior to the
applicable date.

<PAGE>   26



                  (c) As promptly as practicable after the Exchange Date, the
Borrower shall, or shall cause the Parent Company to, deliver to the Agent
certificates issued to each Lender representing the number of fully paid and
nonassessable shares of Parent Company Common Stock into which the Exchange
Amount has been converted in accordance with this Section 2.11. No fractional
shares of Parent Company Common Stock shall be issued upon a exchange pursuant
to this Section 2.11, and instead of any fractional share of Parent Company
Common Stock which would otherwise be issuable upon such exchange, the Borrower
shall pay to the Agent for the account of the Lenders a cash adjustment in
respect of such fraction in an amount equal to (i) such fraction multiplied by
(ii) the Exchange Price.

                  (d) Each Lender covenants and agrees with the Borrower that
the Parent Company Common Stock that may be acquired by such Lender hereunder
will be acquired for its own account and with no intention of distributing or
reselling the Parent Company Common Stock in any transaction in violation of the
securities laws of the United States of America or any state, without prejudice,
however, to such Lender's right at all times to sell or otherwise dispose of all
or any part of the Parent Company Common Stock under a registration statement
under the Securities Act of 1933, as amended ("Securities Act"), and applicable
state securities laws or under an exemption from such registration available
thereunder (including, without limitation, if available, Rule 144A promulgated
thereunder). Each Lender represents that it is and will be at all times an
"accredited investor" as such term is defined in Rule 501(a)(1) or 501(a)(3) of
Regulation D of the Securities Act. If any Lender should in the future decide to
dispose of any of the Parent Company Common Stock, such Lender understands and
agrees that it may do so only(a) in compliance with the Securities Act of 1933,
as amended, and applicable state securities law, as then in effect, and (b) in
the manner contemplated by any registration statement pursuant to which such
Parent Company Common Stock is being offered. Each Lender agrees to the
imprinting, so long as appropriate, of a legend on each certificate representing
Parent Company Common Stock with respect to the limitations on transfers set
forth herein and to the entry of stop-transfer instructions to the effect set
forth above. The breach by any Lender of any of its obligations under this
Section 2.11(d) shall not act as a defense to the payment when due by the
Borrower or any Guarantor of any of the Indebtedness.

         Section 2.12      Repayment of Loans.

                  (a) All accrued interest on the Loans shall be due and payable
in arrears on each Payment Date.

                  (b) All unpaid principal of the Loans shall be due and payable
in full on the Maturity Date.

Following the occurrence of an Event of Default, and as long as such Event of
Default has not been cured, all payments made by the Borrower shall be applied
to the Indebtedness in accordance with Section 6.2(d).

         Section 2.13 Payment Procedure.

                  (a) All payments and prepayments made by the Borrower under
the Notes or this Agreement shall be made to the Agent by wire transfer in
immediately available funds before 2:00 P.M., New York, New York, time on the
date such payment is required to be made to the account of the Agent to such
account in New York, New York, as the Agent may from time to time designate by
notice in writing to the Borrower (the "Agent's Account"). All amounts payable
with respect to this Agreement and the Notes shall be payable only in New York,
New York. Any payment received and accepted by the Agent after such time shall
be considered for all purposes (including the calculation of interest, to the
extent permitted by law) as having been made on the next following Business Day.
The Agent will promptly thereafter cause to be distributed like funds relating
to the payment of principal, interest or fees ratably (other than amounts
payable solely to the Agent or a specific Lender pursuant Section 9.2 or the
fees payable pursuant to Section 2.6(a)), to the Lenders at their respective
Lender Account. If and to the extent that the Agent receives any payment or
prepayment from the Borrower and fails to distribute such payment or prepayment
to the Lenders ratably on the basis of their respective Pro Rata Shares on the
day the Agent receives such payment or prepayment (if received prior to 2:00
P.M. (New York, New York time) on such day) or the next Business Day (if
received after 2:00 P.M. New York, New York time) on such day), then the Agent
shall pay to each Lender such Lender's Pro Rata Share of such payment or
prepayment together with interest thereon at the Federal Funds Rate for each day
from the date such amount should have been distributed by the Agent until such
payment or prepayment is actually distributed to the Lenders.
 All payments and prepayments received shall be applied first to accrued
interest, second to the reduction of principal on account of Loans used for
Acquisitions, and then to the reduction of principal on account of Loans used
for Capital Costs.

                  (b) Unless the Agent shall have received written notice from
the Borrower prior to the date on which any payment is due to the Lenders that
the Borrower will not make such payment in full, the Agent may assume that the
Borrower has made such payment in full to the Agent on such date and the Agent
may, in reliance upon such assumption, cause to be distributed to each Lender on
such date an amount equal to the amount then due such Lender. If and to the
extent the Borrower shall not have so made such payment in full to the Agent,
each Lender shall repay to the Agent forthwith on demand such amount distributed
to such Lender, together with interest, for each day from the date such amount
is distributed to such Lender until the date such Lender repays such amount to
the Agent, at the Federal Funds Rate for such day.

         Section 2.14 Business Days. If the date for any mandatory prepayment or
any other payment provided hereunder or in any other Loan Document falls on a
day which is not a Business Day, then for all purposes of this Agreement and the
other Loan Documents, the same shall be deemed to have fallen on the next
following Business Day, and such extension of time shall in such case be
included in the computation of payments of interest applicable thereto.

         Section 2.15 Illegality. If, after the date hereof, any law, regulation
or treaty or any change therein or in the interpretation thereof by any
authority or agency charged with the administration



                                      -22-
<PAGE>   28



thereof or by any court will make it, in the reasonable opinion of any Lender,
unlawful for such Lender to maintain the Loans or to give effect to its
obligations as contemplated hereby, such Lender will so notify the Agent and the
Borrower, and the aggregate outstanding principal amount of the Loans made by
such Lender, together with the interest accrued thereon and any other amounts
payable to such Lender under the Note, this Agreement or the other Loan
Documents will be paid or prepaid as provided in such notice and such Lender
shall have no further obligation to make Loans under this Agreement.

         Section 2.16 Mortgaged Property. To secure full and complete payment of
all Indebtedness, the Borrower shall execute and deliver to the Agent for the
benefit of the Lenders the Security Instruments creating a second priority lien
(second only to the lien identified in clause (f) of the definition of "Excepted
Liens") and security interest in the Mortgaged Property, subject to Excepted
Liens. Borrower shall execute and deliver or cause to be executed and delivered
such further documents and instruments, including, without limitation, Uniform
Commercial Code financing statements, as the Agent, in its sole discretion,
deems necessary or desirable to evidence and perfect the Liens in the Mortgaged
Property.

         Section 2.17 Setoff. In addition to a right of setoff against (without
prior notice), and as further security for the Indebtedness, the Borrower hereby
grants to the Agent and each Lender a security interest in, all deposits
(general or special, time or demand, provisional or final), money, instruments,
accounts, and other Property of the Borrower now or hereafter on deposit with or
held by such Lender and all other sums at any time credited by or owing from the
Agent or such Lender to the Borrower. Furthermore, should the Agent, any Lender
or any Affiliate thereof enter into one or more Hedging Agreements with the
Borrower at any time, such Agent, Lender or such Affiliate, during the
continuation of any Event of Default, may exercise a right of setoff for any sum
or sums due the Agent or such Lender hereunder against any sum or sums which the
Agent, such Lender or any Affiliate thereof may owe the Borrower under such
Hedging Agreement(s); provided however, that if such Lender or the applicable
Affiliate are in a proceeding of the type described in Section 6.1(g), the right
of setoff under this Section 2.17 shall not be available. Any amounts setoff
pursuant to this Section 2.17 shall be applied to the Indebtedness in accordance
with the terms of this Agreement. The rights and remedies of the Agent, each
Lender and any Affiliate thereof hereunder are in addition to other rights and
remedies (including, without limitation, other rights of setoff) which the
Agent, such Lender or such Affiliate may have.

         Section 2.18 Production Proceeds. From and after the occurrence of a
Default which has not been cured, and subject to the rights of the lenders under
the Senior Loan Agreement and the Subordination Agreement, the Borrower at the
request of the Agent shall direct and cause all purchasers of Hydrocarbons
produced from the Mortgaged Properties to deposit all payments of any nature
whatsoever due and owing by such Persons to the Borrower directly into the
Agent's Account. Funds deposited in the Agent's Account in accordance with the
terms hereof shall be credited when collected to the payment of the Indebtedness
in accordance with Section 6.2(d). In the event that the Borrower cures the
Default, the Agent shall deliver written notice to such purchasers that the
Default has been cured, and instruct them to deliver all future payments to the
Borrower, as



                                      -23-
<PAGE>   29



applicable, in accordance with the Borrower's instructions until such time as
the purchaser receives further notice from the Agent that a Default has occurred
which has not been cured.

         Section 2.19 Sharing of Payments, Etc. If any Lender shall obtain any
payment (whether voluntary, involuntary, through the exercise of any right of
set-off or otherwise) on account of the Loans made by it in excess of its Pro
Rata Share of payments on account of the obtained by all the Lenders, such
Lender shall notify the Agent and forthwith purchase from the other Lenders such
participations in the Loans made by them as shall be necessary to cause such
purchasing Lender to share the excess payment ratably with each of them;
provided, however, that if all or any portion of such excess payment is
thereafter recovered from such purchasing Lender, such purchase from each Lender
shall be rescinded and such Lender shall repay to the purchasing Lender the
purchase price to the extent of such Lender's ratable share (according to the
proportion of (a) the amount of the participation sold by such Lender to the
purchasing Lender as a result of such excess payment to (b) the total amount of
such excess payment) of such recovery, together with an amount equal to such
Lender's ratable share (according to the proportion of (a) the amount of such
Lender's required repayment to the purchasing Lender to (b) the total amount of
all such required repayments to the purchasing Lender) of any interest or other
amount paid or payable by the purchasing Lender in respect of the total amount
so recovered. The Borrower agrees that any Lender so purchasing a participation
from another Lender pursuant to this Section 2.19 may, to the fullest extent
permitted by law, exercise all its rights of payment (including the right of
set-off) with respect to such participation as fully as if such Lender were the
direct creditor of the Borrower in the amount of such participation.

                                    ARTICLE 3
                         REPRESENTATIONS AND WARRANTIES

         The Borrower represents and warrants to the Agent and each Lender that
(each representation and warranty herein is given as of the date hereof and
shall be deemed repeated and reaffirmed on the dates of each Borrowing and,

made with respect to the most recent financial statements delivered to the Agent
pursuant to Section 4.1):

         Section 3.1 Corporate Existence. Each of the Parent Company, the
Borrower and each of its Subsidiaries: (i) is a corporation duly organized,
legally existing and in good standing under the laws of the jurisdiction of its
incorporation; (ii) has all requisite corporate power, and has all material
governmental licenses, authorizations, consents and approvals necessary to own
its assets and carry on its business as now being or as proposed to be

         Section 3.2  Financial Condition.

                  (a) The audited consolidated balance sheet of the Parent
Company and its Consolidated Subsidiaries, as of June 30, 1997 and the related
consolidated statement of operations, stockholders' equity and cash flow of the
Parent Company and its Consolidated Subsidiaries, for the fiscal year ended on
said date, with the opinion thereon of Ernst & Young, LLP heretofore furnished
to the Agent, and the unaudited consolidated balance sheet of the Parent Company
and its Consolidated Subsidiaries as of September 30, 1997 and their related
consolidated statements of operations, stockholders' equity and cash flow of the
Parent Company and its Consolidated Subsidiaries for the 3 month period ended on
such date heretofore furnished to the Agent are complete and correct and fairly
present the consolidated financial condition of the Parent Company and its
Consolidated Subsidiaries as at said dates and the results of its operations for
the fiscal year and the 3 month period on said dates, all in accordance with
GAAP, as applied on a consistent basis (subject, in the case of the interim
financial statements, to normal year-end adjustments).

                  (b) The financial statements referred to in Section 3.2(a)
present fairly, in all material respects, the financial position of the Parent

Subsidiaries has on the date hereof any material Debt, contingent liabilities,
liabilities for taxes, unusual forward or long-term commitments or unrealized or
anticipated losses from any unfavorable commitments, except as referred to or

3.2(a) or in Schedule 3.2 which could reasonably be expected to have a Material
Adverse Effect. Since September 30, 1997, there has been no change or event
having a Material Adverse Effect. Since September 30, 1997, neither the business

3.3 hereto, there is no litigation, legal, administrative or arbitral
proceeding, investigation or other action of any nature pending or, to the
knowledge of the Borrower threatened against or affecting the Parent Company,
the Borrower or any of its Subsidiaries which involves the possibility of any
judgment or liability against the Parent Company, Borrower or any of its
Subsidiaries not fully covered by insurance (except for normal deductibles), and
which would have a Material Adverse Effect.

         Section 3.4 No Breach. Neither the execution and delivery of the Loan
Documents, nor compliance with the terms and provisions hereof will conflict
with or result in a breach of, or require any consent which has not been
obtained as of the date hereof or which if not obtained would have a Material
Adverse Effect under, the respective charter or by-laws of the Parent Company,
the Borrower or any of its Subsidiaries, or any Governmental Requirement or any
agreement or



                                      -25-
<PAGE>   31



instrument to which the Parent Company, the Borrower or any of its Subsidiaries
is a party or by which it is bound or to which it or its Properties are subject,
or constitute a default under any such agreement or instrument, or result in the
creation or imposition of any Lien upon any of the revenues or assets of the
Parent Company, the Borrower or any of its Subsidiaries pursuant to the terms of
any such agreement or instrument other than the Liens created by the Loan
Documents.

         Section 3.5 Authority. The Parent Company, the Borrower and each of its
Subsidiaries have all necessary corporate power and authority to execute,
deliver and perform its obligations under the Loan Documents to which it is a
party; and the execution, delivery and performance by the Parent Company, the
Borrower and each of its Subsidiaries of the Loan Documents to which it is a
party, have been duly authorized by all necessary corporate action on its part;
and the Loan Documents constitute the legal, valid and binding obligations of
the Parent Company, the Borrower and each Subsidiary, enforceable in accordance
with their terms, subject to applicable bankruptcy, insolvency or similar laws
and general principles of equity.

         Section 3.6 Approvals. No authorizations, approvals or consents of, and
no filings or registrations with, any Governmental Authority are necessary for
the execution, delivery or performance by the Parent Company, the Borrower or
any of its Subsidiaries of the Loan Documents or for the validity or
enforceability thereof, except for (a) the recording and filing of the Security
Instruments as required by this Agreement, (b) the listing of the Parent Company
Stock issuable pursuant to Section 2.11 with NASDAQ (or such other market upon
which the Parent Company Stock is then traded), (c) the post-closing filing of a
notice on Form D under the Securities Act of 1993, as amended, with respect to
the issuance of the Notes, (d) a post-closing report on Form 10-QSB under the
Securities Exchange Act of 1934, as amended, with respect to the issuance of the
Notes, and (e) with respect to the Registration Rights Agreement only, those
filings required under applicable securities laws in order to perform under the
Registration Rights Agreement.

         Section 3.7 Use of Borrowings. The proceeds of the Borrowings shall be
used solely for the purposes described in Section 2.2. The Borrower is not
engaged principally, or as one of its important activities, in the business of
extending credit for the purpose, whether immediate, incidental or ultimate, of
buying or carrying margin stock (within the meaning of Regulation G, U or X of
the Board of Governors of the Federal Reserve System) and no part of the
proceeds of any Borrowing hereunder will be used to buy or carry any margin
stock.

         Section 3.8 ERISA.

                  (a) The Parent Company, the Borrower and each of its
Subsidiaries and ERISA Affiliates have complied in all material respects with
ERISA and, where applicable, the Code regarding each Plan.

                  (b) Each Plan is, and has been, maintained in substantial
compliance with ERISA and, where applicable, the Code.




                                      -26-
<PAGE>   32



                  (c) To the best knowledge of the Borrower, no act, omission or
transaction has occurred which could result in imposition on the Parent Company,
the Borrower or any of its Subsidiaries or ERISA Affiliates (whether directly or
indirectly) of (i) either a civil penalty assessed pursuant to section 502(c),
(i) or (1) of ERISA or a tax imposed pursuant to Chapter 43 of Subtitle D of the
Code or (ii) breach of fiduciary duty liability damages under section 409 of
ERISA.

                  (d) No Plan (other than a defined contribution plan) or any
trust created under any such Plan has been terminated since September 2, 1974.
No liability to the PBGC (other than for the payment of current premiums which
are not past due) by the Parent Company, the Borrower or any of its Subsidiaries
or ERISA Affiliates has been or is expected by the Parent Company, the Borrower
or any of its Subsidiaries or ERISA Affiliates to be incurred with respect to
any Plan. No ERISA Event with respect to any Plan has occurred.

                  (e) Full payment when due has been made of all amounts which
the Parent Company, the Borrower or any of its Subsidiaries or ERISA Affiliates
is required under the terms of each Plan or applicable law to have paid as
contributions to such Plan, and no accumulated funding deficiency (as defined in
section 302 of ERISA and section 412 of the Code), whether or not waived, exists
with respect to any Plan.

                  (f) The actuarial present value of the benefit liabilities
under each Plan which is subject to Title IV of ERISA does not, as of the end of
the Parent Company's most recently ended fiscal year, exceed the current value
of the assets (computed on a plan termination basis in accordance with Title IV
of ERISA) of such Plan allocable to such benefit liabilities. The term
"actuarial present value of the benefit liabilities" shall have the meaning
specified in section 4041 of ERISA.

                  (g) None of the Parent Company, the Borrower or any of its
Subsidiaries or ERISA Affiliates sponsors, maintains, or contributes to an
employee welfare benefit plan, as defined in section 3(1) of ERISA, including,
without limitation, any such plan maintained to provide benefits to former
employees of such entities, that may not be terminated by the Parent Company,
the Borrower or any of its Subsidiaries or ERISA Affiliates in its sole
discretion at any time without any material liability.

                  (h) None of the Parent Company, the Borrower or any of its
Subsidiaries or ERISA Affiliates sponsors, maintains or contributes to, or has
at any time in the preceding six calendar years, sponsored, maintained or
contributed to, any Multiemployer Plan.

                  (i) None of the Parent Company, the Borrower or any of its
Subsidiaries or ERISA Affiliates is required to provide security under section
401(a) (29) of the Code due to a Plan amendment that results in an increase in
current liability for the Plan.

         Section 3.9 Taxes. Each of the Parent Company, the Borrower and its
Subsidiaries has filed all United States Federal income tax returns and, to the
best of the Borrower's knowledge, all



                                      -27-
<PAGE>   33



other tax returns which are required to be filed by them and have paid all
material taxes due pursuant to such returns or pursuant to any assessment
received by the Parent Company, the Borrower or any of its Subsidiaries, except
for those being contested in good faith by appropriate proceedings and for which
adequate reserves have been provided in accordance with GAAP. The charges,
accruals and reserves on the books of the Parent Company, the Borrower and its
Subsidiaries in respect of taxes and other governmental charges are, in the
opinion of the Borrower, adequate. No tax Lien has been filed and, to the
knowledge of the Borrower, no claim is being asserted with respect to any such
tax, fee or other charge which could reasonably be expected to have a Material
Adverse Effect.

         Section 3.10      Titles, etc.

                  (a) Except as set out in Schedule 3.10, each of the Parent
Company, the Borrower and its Subsidiaries has good and defensible title to its
material (individually or in the aggregate) Properties, free and clear of all
Liens except Liens permitted by Section 5.2. Except as set forth in Schedule
3.10, after giving full effect to the Excepted Liens, the Parent Company, the
Borrower and its Subsidiaries, as applicable, owns the net interests in
production attributable to the lands and leases reflected in the most recently
delivered Reserve Report and the ownership of such Properties shall not in any
material respect obligate such Person to bear the costs and expenses relating to
the maintenance, development and operations of each such Property in an amount
in excess of the working interest of each Property set forth in the most
recently delivered Reserve Report. All information contained in the most
recently delivered Reserve Report is true and correct in all material respects
as of the date thereof.

                  (b) All material leases and agreements necessary for the
conduct of the business of the Parent Company, the Borrower and its Subsidiaries
are valid and subsisting and are in full force and effect. There exists no
default or event or circumstance which with the giving of notice or the passage
of time or both would give rise to a default under any such lease or leases
which would affect in any material respect the conduct of the business of the
Parent Company, the Borrower and its Subsidiaries taken as a whole or which
would have a Material Adverse Effect.

                  (c) The rights, properties and other assets presently owned,
leased or licensed by the Parent Company, the Borrower and its Subsidiaries
including, without limitation, all easements and rights of way, include all
rights, Properties and other assets reasonably necessary to permit the Parent
Company, the Borrower and its Subsidiaries to conduct their business in all
material respects in the same manner as its business has been conducted prior to
the date hereof.

                  (d) All of the assets and Properties of the Parent Company,
the Borrower and its Subsidiaries which are reasonably necessary for the
operation of its business are in good working condition and are maintained in
accordance with prudent business standards.

         Section 3.11 No Material Misstatements. No written information,
statement, exhibit, certificate, document or report furnished to the Agent by
the Parent Company, the Borrower or any of its Subsidiaries in connection with
the negotiation of this Agreement contained any material



                                      -28-
<PAGE>   34



misstatement of fact or omitted to state a material fact misleading in the light
of the circumstances in which made. There is no fact known to the Borrower which
has a Material Adverse Effect or in the future is reasonably likely to have (so
far as the Borrower can now foresee) a Material Adverse Effect and which has not
been set forth in this Agreement or the other documents, certificates and
statements furnished to the Agent by or on behalf of the Parent Company, the
Borrower or any of its Subsidiaries prior to, or on, the date hereof in
connection with the transactions contemplated hereby. The Borrower has delivered
to the Agent a true and complete copy of the Offering Memorandum dated July 15,
1995, regarding the DEM Subordinated Debt ("Offering Memorandum"). There has
been no amendment or modification to the terms and provisions of the DEM
Subordinated Debt, as described in the Offering Memorandum.

         Section 3.12 Investment Company Act. Neither the Parent Company, the
Borrower nor any of its Subsidiaries is an "investment company" or a company
"controlled" by an "investment company," within the meaning of the Investment
Company Act of 1940, as amended.

         Section 3.13 Public Utility Holding Company Act. Neither the Parent
Company, the Borrower nor any of its Subsidiaries is a "holding company," or a
"subsidiary company" of a "holding company," or an "affiliate" of a "holding
company" or of a "subsidiary company" of a "holding company," or a public
utility" within the meaning of the Public Utility Holding Company Act of 1935,
as amended.

         Section 3.14 Subsidiaries and Partnerships. Except as set forth on
Schedule 3.14, the Borrower has no Subsidiaries and has no interest in any
partnerships. Schedule 3.14 sets forth the principal place of business of each
such Subsidiary and the ownership interest of the Borrower in such Subsidiary.

         Section 3.15 Location of Business and Offices. The Borrower's principal
place of business and chief executive offices are located at the address stated
in Section 8.1(a). The principal place of business and chief executive office of
each Subsidiary are located at the addresses stated on Schedule 3.14.

         Section 3.16 Defaults. Neither the Parent Company, the Borrower nor any
of its Subsidiaries is in default nor has any event or circumstance occurred
which, but for the expiration of any applicable grace period or the giving of
notice, or both, would constitute a default under any material agreement or
instrument to which any such Person is a party or by which any such Person is
bound which default would have a Material Adverse Effect. No Default hereunder
or under the Senior Loan Agreement has occurred and is continuing.

         Section 3.17 Environmental Matters. Except (i) as provided in Schedule
3.17 or (ii) as would not have a Material Adverse Effect (or with respect to
(c), (d) and (e) below, where the failure to take such actions would not have a
Material Adverse Effect):

                  (a) Neither any Property of the Parent Company, the Borrower
or any of its Subsidiaries nor the operations conducted thereon violate any
order or requirement of any court or Governmental Authority or any Environmental
Laws.

                  (b) Without limitation of clause (a) above, no Property of the
Parent Company, the Borrower or any of its Subsidiaries nor the operations
currently conducted thereon or, to the best knowledge of the Borrower, by any
prior owner or operator of such Property or operation, are in violation of or
subject to any existing, pending or (to the knowledge of the Borrower)
threatened action, suit, investigation, inquiry or proceeding by or before any
court or Governmental Authority or to any remedial obligations under
Environmental Laws.

                  (c) All notices, permits, licenses or similar authorizations,
if any, required to be obtained or filed in connection with the operation or use
of any and all Property of the Parent Company, the Borrower and each of its
Subsidiaries, including without limitation past or present treatment, storage,
disposal or release of a hazardous substance or solid waste into the
environmental, have been duly obtained or filed, and the Parent Company, the
Borrower and each of its Subsidiaries are in compliance with the terms and
conditions of all such notices, permits, licenses and similar authorizations.

                  (d) All hazardous substances, solid waste, and oil and gas
exploration and production wastes, if any, generated at any and all Property of
the Parent Company, the Borrower or any of its Subsidiaries have in the past
been transported, treated and disposed of in accordance with Environmental Laws
and so as not to pose an imminent and substantial endangerment to public health
or welfare or the environment, and, to the best knowledge of the Borrower, all
such transport carriers and treatment and disposal facilities have been and are
operating in compliance with Environmental Laws and so as not to pose an
imminent and substantial endangerment to public health or welfare or the
environment, and are not the subject of any existing, pending or (to the
knowledge of the Borrower) threatened action, investigation or inquiry by any
Governmental Authority in connection with any Environmental Laws.

                  (e) The Borrower has taken all steps reasonably necessary to
determine and has determined that no hazardous substances, solid waste, or oil
and gas exploration and production wastes, have been disposed of or otherwise
released and there has been no threatened release of any hazardous substances on
or to any Property of the Parent Company, the Borrower or any of its
Subsidiaries except in compliance with Environmental Laws and so as not to pose
an imminent and substantial endangerment to public health or welfare or the
environment.

                  (f) To the extent applicable, all Property of the Parent
Company, the Borrower and each of its Subsidiaries currently satisfies all
design, operation, and equipment requirements imposed by OPA or scheduled as of
the date hereof to be imposed by OPA during the term of this Agreement, and the
Parent Company, the Borrower does not have any reason to believe that such
Property, to the extent subject to OPA, will not be able to maintain compliance
with OPA requirements during the term of this Agreement.

                  (g) Neither the Parent Company, the Borrower nor any of its
Subsidiaries has any known contingent liability in connection with any release
or threatened release of any oil, hazardous substance or solid waste into the

Borrower nor any of its Subsidiaries has violated any Governmental Requirement
or failed to obtain any license, permit, franchise or other governmental
authorization necessary for the ownership of any of its Properties or the
conduct of its business, which violation or failure would have (in the event
such violation or failure were asserted by any Person through appropriate
action) a Material Adverse Effect. Except for such acts or failures to act as
would not have a Material Adverse Effect, the Mortgaged Properties have been
maintained, operated and developed in a good and workmanlike manner and in
substantial conformity with all applicable laws and all rules, regulations and
orders of all duly constituted authorities having jurisdiction and in
substantial conformity with the provisions of all leases, subleases or other
contracts comprising a part of the Hydrocarbon Interests and other contracts and
agreements forming a part of the Mortgaged Properties; specifically in this
connection, (a) after the date hereof, no Mortgaged Property is subject to
having allowable production reduced below the full and regular allowable
(including the maximum permissible tolerance) because of any overproduction
(whether or not the same was permissible at the time) prior to the date hereof
and (b) none of the wells comprising a part of the Mortgaged Properties are
deviated from the vertical more than the maximum permitted by applicable laws,
regulations, rules and orders, and such wells are, in fact, bottomed under and
are producing from, and the well bores are wholly within, the Mortgaged
Properties (or in the case of wells located on properties unitized therewith,
such unitized properties).

         Section 3.19 Insurance. Schedule 3.19 attached hereto contains an
accurate and complete description of all material policies of fire, liability,

full force and effect, all premiums with respect thereto covering all periods up
to an including the date of the closing have been paid, and no notice of
cancellation or termination has been received with respect to any such policy.
Such policies are sufficient for substantial compliance with all requirements of
law and of all agreements to which the Parent Company, the Borrower or any of
its Subsidiaries is a party; are valid, outstanding and enforceable policies;
provide adequate insurance coverage in at least such amounts and against at
least such risks (but including in any event public liability) as are usually
insured against in the same general area by companies engaged in the same or a
similar business for the assets and operations of the Parent Company, the
Borrower and each of its Subsidiaries; will remain in full force and effect
through the respective dates set forth in Schedule 3.19 without the payment of
additional premiums; and will not in any way be affected by, or terminate or

Borrower and its Subsidiaries and their respective Board of Directors or
officers have designated as being self insured. Neither the Parent Company, the
Borrower nor any of its Subsidiaries has been refused any insurance with respect
to its assets or operations, nor has its coverage been limited



                                      -31-

termination date and notional amounts or volumes), the net mark to market value
thereof, all credit support agreements relating thereto (including any margin
required or supplied), and the counterparty to each such agreement.

         Section 3.21 Restriction on Liens. Neither the Parent Company, the
Borrower nor any of its Subsidiaries (other than Non-Recourse Subsidiaries) is a
party to any agreement or arrangement (other than this Agreement and the
Security Instruments), or subject to any order, judgment, writ or decree, which
either restricts or purports to restrict its ability to grant Liens to other
Persons on or in respect of their respective assets or Properties, except for
such restrictions as are contained in the documents and agreements evidencing
the DEM Subordinated Debt and the Senior Debt; provided that such restrictions
do not impair the ability of the Parent Company, the Borrower, or any of its
Subsidiaries (other than Non-Recourse Subsidiaries) to grant Liens to the Agent
and the Banks except as provided in the Senior Loan Agreement and the
Subordination Agreement.

         Section 3.22 Gas Imbalances. As of the date hereof, except as set forth

or any of its Subsidiaries, and such list correctly sets forth the names of the
debtor or lessee and creditor or lessor with respect to the Debt or lease
obligations outstanding or to be outstanding and the property subject to any
Lien securing such Debt or lease obligation. Also set forth on Schedule 3.23
hereto is a complete and correct list of all material agreements and other
instruments of the Parent Company, the Borrower and its Subsidiaries relating to
the purchase, transportation by pipeline, gas processing, marketing, sale and
supply of natural gas and other Hydrocarbons, but in any event, any such
agreement or other instrument that will account for more than 20% of the sales
of the Parent Company, the Borrower and its Subsidiaries during the Parent
Company's fiscal year.

                  (b) In the event of an unscheduled redetermination, the

                  (c) With the delivery of each Reserve Report, the Borrower

forth on an exhibit to the certificate, on a net basis there are no gas
imbalances, take or pay or other prepayments with respect to its Oil and Gas
Properties evaluated in such Reserve Report which would require the Parent
Company, the Borrower, or any Guarantor, as applicable, to deliver Hydrocarbons
produced from such Oil and Gas Properties at some future time without then or
thereafter receiving full payment thereof, (iv) none of the Oil and Gas
Properties of the Parent Company, the Borrower, or any Guarantor have been sold
since the date of the last Borrowing Base determination except as set forth on
an exhibit to the certificate, which certificate shall list all of such Oil and
Gas Properties sold and in such detail as reasonably required by the Agent, (v)
attached to the certificate is a list of its Oil and Gas Properties added to and
deleted from the immediately prior Reserve Report and a list of all Persons
disbursing proceeds to the Parent Company, the Borrower, or any Guarantor, as
applicable, from such Person's Oil and Gas Properties, (vi) except as set forth
on a schedule attached to the certificate all of the Oil and Gas Properties

                  (d) As soon as available and in any event within 45 days after
the end of the fiscal quarter, the Borrower shall provide (i) a production
report, in the form currently prepared internally by the Borrower and which has

the Borrower shall also provide projections and budgets of the Borrower and its
Subsidiaries for the forthcoming fiscal year, which shall include, on a monthly

and cash flow statements and balance sheets, in each case together with the
analysis and discussion of management of such projections, all certified by a

         Section 4.8       Title Information.

                  (a) On or before the delivery to the Agent of each Reserve
Report required by Section 4.7(a), the Borrower will deliver title information
in form and substance reasonably satisfactory to the Agent covering the Oil and
Gas Properties evaluated by such Reserve Report and included in the Borrowing
Base that were not included in the immediately preceding Borrowing Base
evaluation, so that the Agent shall have received together with title
information previously delivered to the Agent, satisfactory title information on
at least 85% of the SEC Value of the Oil and Gas Properties evaluated by such
Reserve Report and included in the Borrowing Base. The Borrower shall cure any
title defects or exceptions which are not Excepted Liens raised by the title
information within 60 days after a request by the Agent to cure such defects or
exceptions.

                  (b) If the Borrower is unable to cure any title defect
requested by the Agent to be cured within the 60 day period, such default shall
not be a Default or an Event of Default, but instead the Agent shall have the
right to exercise the following remedy in its sole discretion from time to time,
and any failure to so exercise this remedy at any time shall not be a waiver as
to future exercise of the remedy by the lender. To the extent that the Agent is
not satisfied with title to any Mortgaged Property after the time period in
Section 4.8(a) has elapsed, such unacceptable Mortgaged Property shall not count
towards the 85% requirement, and the Agent may send a notice to the Borrower
that the then outstanding Borrowing Base shall be reduced by an amount as
determined by the Agent to cause the Borrower to be in compliance with the
requirement to provide acceptable title information on 85% of the SEC Value of
the Oil and Gas Properties included in the Borrowing Base. The new Borrowing
Base shall become effective immediately after receipt of such notice.

         Section 4.9       Additional Collateral.

                  (a) The Borrower shall grant, and shall cause the Parent
Company and each Guarantor to grant, to the Agent for the benefit of the Lenders
as security for the Indebtedness a second-priority Lien interest (subject only
to Excepted Liens) on such Person's interest in any Oil and Gas Properties not
already subject to a Lien of the Security Instruments such that the Mortgaged
Property shall include at least 85% of the SEC Value of each of proved producing
and the total Proved Reserves at all times, which Lien will be created and
perfected by and in accordance with the provisions of deeds of trust, security
agreements and financing statements, or other Security Instruments, all in form
and substance satisfactory to the Agent in its sole discretion and in sufficient
executed (and acknowledged where necessary or appropriate) counterparts for
recording purposes.

                  (b) If the agent under the Senior Loan Agreement requests the
Parent Company, the Borrower, or any Guarantor to grant as security for the
Senior Debt additional Liens in such Person's interest in any Oil and Gas
Properties, the Borrower shall promptly deliver to the Agent a copy of such
request. Within 10 days of the granting of any Liens in any Oil and Gas
Properties as security for the Senior Debt, the Parent Company and the Borrower
will, and will cause each Guarantor, to grant to the Agent for the benefit of
the Lenders as security for the Indebtedness a



                                      -39-
<PAGE>   45
second-priority Lien (subject only to Excepted Liens) on any such Oil and Gas
Properties not already subject to a Lien of the Security Instruments.

                  (c) Concurrently with the granting of the Lien or other action
referred to in Sections 4.9(a) and 4.9(b) above, the Borrower will (i) provide
to the Agent title information in form and substance satisfactory to the Agent
in its sole discretion with respect to the appropriate Person's interests in
such Oil and Gas Properties; and (ii) promptly after the filing of any new
Security Instrument in any state, upon the reasonable request of the Agent,
provide to the Agent an opinion addressed to the Agent in form and substance
satisfactory to the Agent in its sole discretion from counsel acceptable to
Agent, stating that the Security Instrument is valid, binding and enforceable in
accordance with its terms and in legally sufficient form for such jurisdiction.

         Section 4.10 ERISA Information and Compliance. The Parent Company and
the Borrower will promptly furnish and will cause its Subsidiaries and ERISA
Affiliates to promptly furnish to the Agent (a) promptly after the filing
thereof with the United States Secretary of Labor, the Internal Revenue Service
or the PBGC, copies of each annual and other report with respect to each Plan or
any trust created thereunder, (b) immediately upon becoming aware of the
occurrence of any ERISA Event or of any "prohibited transaction," as described
in section 406 of ERISA or in section 4975 of the Code, in connection with any
Plan or any trust created thereunder, a written notice signed by a Responsible
Officer specifying the nature thereof, what action the Parent Company, the
Borrower, its Subsidiaries or ERISA Affiliate is taking or proposes to take with
respect thereto, and, when known, any action taken or proposed by the Internal
Revenue Service, the Department of Labor or the PBGC with respect thereto, and
(c) immediately upon receipt thereof, copies of any notice of the PBGC's
intention to terminate or to have a trustee appointed to administer any Plan.
With respect to each Plan (other than a Multiemployer Plan), the Parent Company

Affiliates to, (i) satisfy in full and in a timely manner, without incurring any
late payment or underpayment charge or penalty and without giving rise to any
lien, all of the contribution and funding requirements of section 412 of the

and of section 302 of ERISA (determined without regard to sections 303, 304 and
306 of ERISA), and (ii) pay, or cause to be paid, to the PBGC in a timely
manner, without incurring any late payment or underpayment charge or penalty,
all premiums required pursuant to sections 4006 and 4007 or ERISA.

Agent's directors, officers, agents or employees shall be liable for any action
taken or omitted to be taken (including the Agent's own negligence) by it or
them under or in connection with this Agreement or the other Loan Documents,
except for its or their own gross negligence or willful misconduct. Without
limitation of the generality of the foregoing, the Agent: (a) may treat the
payee of any Note as the



                                      -55-
<PAGE>   61
holder thereof until the Agent receives written notice of the assignment or
transfer thereof signed by such payee and in form satisfactory to the Agent; (b)
may consult with legal counsel (including counsel for the Borrower), independent
public accountants and other experts selected by it and shall not be liable for
any action taken or omitted to be taken in good faith by it in accordance with
the advice of such counsel, accountants or experts; (c) makes no warranty or
representation to any Lender and shall not be responsible to any Lender for any
statements, warranties or representations made in or in connection with this
Agreement or the other Loan Documents; (d) shall not have any duty to ascertain
or to inquire as to the performance or observance of any of the terms, covenants
or conditions of this Agreement or any other Loan Document on the part of the
Parent Company, the Borrower, or its Subsidiaries or to inspect the property
(including the books and records) of such Persons; (e) shall not be responsible
to any Lender for the due execution, legality, validity, enforceability,
genuineness, sufficiency or value of this Agreement or any other Loan Document;
and (f) shall incur no liability under or in respect of this Agreement or any
other Loan Document by acting upon any notice, consent, certificate or other
instrument or writing (which may be by telecopy, telegram, cable or telex)
reasonably believed by it to be genuine and signed or sent by the proper party
or parties.

         Section 8.3 The Agent and Its Affiliates. With respect to its
Commitment, the Loans made by it and the Note issued to it, the Agent shall have
the same rights and powers under this Agreement as any other Lender and may
exercise the same as though it were not an Agent hereunder. The term "Lender" or
"Lenders" shall, unless otherwise expressly indicated, include the Agent in its
individual capacity. The Agent and its Affiliates may accept deposits from, lend
money to, act as trustee under indentures of, and generally engage in any kind
of business with, the Parent Company, the Borrower or any of its Subsidiaries,
and any Person who may do business with or own securities of the Parent Company,
the Borrower, or any such Subsidiary, all as if the Agent were not an agent
hereunder and without any duty to account therefor to the Lenders.

         Section 8.4 Lender Loan Decision. Each Lender acknowledges that it has,
independently and without reliance upon the Agent or any other Lender and based
on the financial statements referred to in Section 3.2 and such other documents
and information as it has deemed appropriate, made its own credit analysis and
decision to enter into this Agreement. Each Lender also acknowledges that it
will, independently and without reliance upon the Agent or any other Lender and
based on such documents and information as it shall deem appropriate at the
time, continue to make its own credit decisions in taking or not taking action
under this Agreement.

         Section 8.5 Indemnification. The Lenders severally agree to indemnify
the Agent and each Affiliate thereof and their respective directors, officers,
employees and agents (to the extent not reimbursed by the borrower), according
to their respective pro rata shares from and against any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements of any kind or nature whatsoever which may be imposed
on, incurred by, or asserted against the Agent in any way relating to or arising
out of this Agreement or any action taken or omitted by the Agent under this
Agreement or any other Loan Document (INCLUDING THE AGENT'S OWN NEGLIGENCE),
provided that no Lender shall be liable for any portion of such


                                      -56-
<PAGE>   62
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements resulting from the Agent's gross negligence or
willful misconduct. Without limitation of the foregoing, each Lender agrees to
reimburse the Agent promptly upon demand for its ratable share of any
out-of-pocket expenses (including counsel fees) incurred by the agent in
connection with the preparation, execution, delivery, administration,
modification, amendment or enforcement (whether through negotiations, legal
proceedings or otherwise) of, or legal advice in respect of rights or
responsibilities under, this Agreement or any other Loan Document, to the extent
that the Agent is not reimbursed for such expenses by the Borrower.

         Section 8.6 Successor Agent. The Agent may resign at any time by giving
written notice thereof to the Lenders and the Borrower and may be removed at any
time with cause by the Majority Lenders upon receipt of written notice from the
Majority Lenders to such effect. Upon receipt of notice of any such resignation
or removal, the Majority Lenders shall have the right to appoint a successor
Agent with, if no Default exists, the consent of the Borrower, which consent
shall not be unreasonably withheld. If no successor Agent shall have been so
appointed by the Majority Lenders with the consent of the Borrower, if required,
and shall have accepted such appointment, within 30 days after the retiring
Agent's giving of notice of resignation or the Majority Lenders' removal of the
retiring Agent, then the retiring Agent may, on behalf of the Lenders and the
Borrower, appoint a successor Agent, which shall be an Eligible Assignee. Upon
the acceptance of any appointment as Agent by a successor Agent, such successor
Agent shall thereupon succeed to and become vested with all the rights, powers,
privileges and duties of the retiring Agent, and the retiring Agent shall be
discharged from its duties and obligations under this Agreement and the other
Loan Documents. After any retiring Agent's resignation or removal hereunder as
Agent, the provisions of this Article 8 shall inure to its benefit as to any
actions taken or omitted to be taken by it while it was Agent this Agreement and
the other Loan Documents.

                                    ARTICLE 9
                                  MISCELLANEOUS

         Section 9.1 Notices. Any notices required or permitted to be given
under or in connection with this Agreement, the other Loan Documents (except as
may otherwise be expressly required therein) or the Note shall be in writing and
shall be mailed by first class or express mail, postage prepaid, or sent by
telex, telegram, telecopy or other similar form of rapid transmission, or
personally delivered to the receiving party. All such communications shall be
mailed, sent or delivered to the intended recipient at addresses set forth below
its signature block below (or to such other address as shall be designated by
such party in a notice to the other party).

         Any communication so addressed and mailed shall be deemed to be given
when so mailed, except that Borrowing Requests or communications related to
Borrowing Requests shall not be effective until actually received by the Agent;
and any notice so sent by rapid transmission shall be deemed to be given when
receipt of such transmission is acknowledged or confirmed, and any communication
so delivered in person shall be deemed to be given when receipted for by, or

received by, an authorized officer of the Borrower, the Agent, or any applicable
Lender, as the case may be.

         Section 9.2 Amendments, Etc. No amendment or waiver of any provision of
this Agreement, the Notes, or any other Loan Document (except for the
Registration Rights Agreement), nor consent to any departure by the Parent
Company, the Borrower or any of its Subsidiaries therefrom, shall in any event
be effective unless the same shall be in writing and signed by (i) the Majority
Lenders and (ii) the Parent Company, the Borrower, or its Subsidiaries, as
applicable, and then such waiver or consent shall be effective only in the
specific instance and for the specific purpose for which given; provided,
however, that no amendment, waiver or consent shall, unless in writing and
signed by all the Lenders, do any of the following: (a) waive any of the
conditions specified in Article 7, (b) increase the Commitments of the Lenders
(other than increases of the Borrowing Base in accordance with the terms of this
Agreement), (c) reduce the principal of, or interest on, the Notes or any fees
or other amounts payable hereunder or under any other Loan Document, (d)

recent Reserve Reports) of all Mortgaged Property released without the consent
of all the Lenders to exceed $1,000,000 during any calendar year or (2) any
Guaranty, (g) amend the definitions of "Majority Lenders" and "Maturity Date",
or (h) changes any requirement for the consent or approval of all Lenders to a

addition to the Lenders required above to take such action, affect the rights or
duties of the Agent under this Agreement or any other Loan Document and (2)
amendments, waivers, and consents regarding the Registration Rights Agreement
shall be made in accordance with the terms thereof.

         Section 9.3 No Waiver; Remedies. No failure on the part of any Lender
or the Agent to exercise, and no delay in exercising, any right hereunder or
under any Credit Document shall operate as a waiver thereof; nor shall any
single or partial exercise of any such right preclude any other or further
exercise thereof or the exercise of any other right. The remedies herein
provided are cumulative and not exclusive of any remedies provided by law.

         Section 9.4 Indemnities.

                  (a)      The Borrower agrees to:

                           (i) pay any and all present and future stamp and

result of, arising out of or in any way related to (A) any actual or proposed
use by the Borrower of the proceeds of any of the Loans, (B) the operations of

                                      -59-
<PAGE>   65
which, though lawful and fully permissible at the time, could result in present
liability, (D) the presence, use, release, storage, treatment or disposal of any
hazardous substances or solid wastes, on or at any of the Properties owned or
operated by the Borrower, the Parent Company, or its Subsidiaries including all
oil and gas exploration and production wastes that may present an endangerment
to public health or welfare or the environment, even if such wastes are
specifically exempt from classification as hazardous substances or solid wastes
pursuant to CERCLA or RCRA or the state analogues to those statutes, or (E) any
other environmental, health or safety condition in connection with this
Agreement, the Note or any other Loan Document, provided, however, no indemnity
shall be afforded under Sections 9.4(a)(v)(B) and 9.4(a)(v)(D) in respect of any
Property for any occurrence arising during the period after which the
indemnitee, its successors or assigns shall have acquired effective management
and control of such Property through receivership or foreclosure, deed in lieu
of foreclosure or otherwise.

                  (b) In the case of any indemnification hereunder, the Agent,
each Lender, or other Person indemnified hereunder shall give notice to the

shall have the non-exclusive right to join in the defense against any such claim
or demand provided that if the Borrower provides a defense, the indemnitee shall

asserted against the indemnitee to be indemnified pursuant to this Section 9.4.

                  (d) The Borrower's obligations under this Section 9.4 shall
survive any termination of this Agreement and the payment of the Notes.

         Section 9.5 Invalidity. In the event that any one or more of the
provisions contained in the Note, this Agreement or in any other Loan Document
shall, for any reason, be held invalid, illegal or unenforceable in any respect,
such invalidity, illegality or unenforceability shall not affect any other
provision of the Note, this Agreement or any other Loan Document.

         Section 9.6 Survival of Agreements. All representations and warranties
of the Borrower herein or in the other Loan Documents, and all covenants and
agreements herein not fully performed before the effective date or dates of this
Agreement and of the other Loan Documents, shall survive such date or dates. The
obligations of the Borrower under Section 9.4 shall survive the repayment of the
Loans and the termination of the Commitment. To the extent that any payments on
the Indebtedness or proceeds of any collateral are subsequently invalidated,
declared to be fraudulent


                                      -60-
<PAGE>   66
or preferential, set aside or required to be repaid to a trustee, debtor in
possession, receiver or other Person under any bankruptcy law, common law or
equitable cause, then to such extent, the Indebtedness so satisfied shall be
revived and continue as if such payment or proceeds had not been received and
the Agent's and the Lenders' Liens, security interests, rights, powers and
remedies under this Agreement and each Security Instrument shall continue in
full force and effect. In such event, each Security Instrument shall be
automatically reinstated and the Borrower shall take such action as may be
reasonably requested by the Agent to effect such reinstatement.

         Section 9.7 Lender Assignments and Participations.

                  (a) Assignments. Any Lender may assign to one or more Eligible
Assignees all or any portion of its rights and obligations under this Agreement
(including, without limitation, all or a portion of its Commitment, the Loans
owing to it, and the Note held by it; provided, however, that (i) each such
assignment shall be of a constant, and not a varying, percentage of all of such
Lender's rights and obligations under this Agreement, (ii) each such assignment
shall be to an Eligible Assignee, (iii) the parties to each such assignment
shall execute and deliver to the Agent, for its acceptance and recording in the
Register, an Assignment and Acceptance, together with the Note subject to such
assignment, and (iv) each Eligible Assignee (other than the Eligible Assignee of
the Agent) shall pay to the Agent a $2,500 administrative fee. Upon such
execution, delivery, acceptance and recording, from and after the effective date
specified in each Assignment and Acceptance, which effective date shall be at
least three Business Days after the execution thereof, (A) the assignee
thereunder shall be a party hereto for all purposes and, to the extent that
rights and obligations hereunder have been assigned to it pursuant to such
Assignment and Acceptance, have the rights and obligations of a Lender hereunder
and (B) such Lender thereunder shall, to the extent that rights and obligations
hereunder have been assigned by it pursuant to such Assignment and Acceptance,
relinquish its rights and be released from its obligations under this Agreement
(and, in the case of an Assignment and Acceptance covering all or the remaining
portion of such Lender's rights and obligations under this Agreement, such
Lender shall cease to be a party hereto but all indemnification provisions
contained herein shall continue to inure for the benefit of such departing
Lender with respect to matters arising during the period such Lender was a party
hereto).

                  (b) Term of Assignments. By executing and delivering an
Assignment and Acceptance, the Lender thereunder and the assignee thereunder
confirm to and agree with each other and the other parties hereto as follows:
(i) other than as provided in such Assignment and Acceptance, such Lender makes
no representation or warranty and assumes no responsibility with respect to any
statements, warranties or representations made in or in connection with this
Agreement or the execution, legality, validity, enforceability, genuineness,
sufficiency of value of this Agreement or any other instrument or document
furnished pursuant hereto; (ii) such Lender makes no representation or warranty
and assumes no responsibility with respect to the financial condition of the
Borrower or its Subsidiaries or the performance or observance by the Borrower or
its Subsidiaries of any of their obligations under this Agreement or any other
instrument or document furnished pursuant hereto; (iii) such assignee confirms
that it has received a copy of this Agreement, together with copies of the
Financial Statements (or its most recently furnished financial


                                      -61-
<PAGE>   67
statements pursuant to Section 4.1) and such other documents and information as
it has deemed appropriate to make its own credit analysis and decision to enter
into such Assignment and Acceptance; (iv) such assignee will, independently and
without reliance upon the Agent, such Lender or any other Lender and based on
such documents and information as it shall deem appropriate at the time,
continue to make its own credit decisions in taking or not taking action under
this Agreement; (v) such assignee appoints and authorizes the Agent to take such
action as agent on its behalf and to exercise such powers under this Agreement
as are delegated to the Agent by the terms hereof, together with such powers as
are reasonably incidental thereto; and (vi) such assignee agrees that it will
perform in accordance with their terms all of the obligations which by the terms
of this Agreement are required to be performed by it as a Lender.

                  (c) The Register. The Agent shall maintain at its address
referred to in Section 9.1 a copy of each Assignment and Acceptance delivered to
and accepted by it and a register for the recordation of the names and addresses
of the Lenders and the Commitment of, and principal amount of the Loans owing
to, each Lender from time to time (the "Register"). The entries in the Register
shall be conclusive and binding for all purposes, absent manifest error, and the
Borrower, the Agent and the Lenders may treat each Person whose name is recorded
in the Register as a Lender hereunder for all purposes of this Agreement. The
Register shall be available for inspection by the Borrower or any Lender at any
reasonable time and from time to time upon reasonable prior notice.

                  (d) Procedures. Upon its receipt of an Assignment and
Acceptance executed by a Lender and an Eligible Assignee, together with the
Notes subject to such assignment, the Agent shall, if such Assignment and
Acceptance has been completed and is in substantially the form of the attached
Exhibit A, (i) accept such Assignment and Acceptance, (ii) record the
information contained therein in the Register, and (iii) give prompt notice
thereof to the Borrower. Within five Business Days after its receipt of such
notice, the Borrower, with its own attorney's fees being its own expense, shall
execute and deliver to the Agent in exchange for the surrendered Notes a new
Note to the order of such Eligible Assignee in an amount equal to the Commitment
assumed by it pursuant to such Assignment and Acceptance and, if such Lender has
retained any Commitment hereunder, a new Note to the order of such Lender in an
amount equal to the Commitment retained by it hereunder. Such new Notes shall be
dated the effective date of such Assignment and Acceptance.

                  (e) Participations. Each Lender may sell participations to one
or more Persons in or to all or a portion of its rights and obligations under
this Agreement (including, without limitation, all or a portion of its
Commitment, the Loans owing to it, and the Note held by it); provided, however,
that (i) such Lender's obligations under this Agreement (including, without
limitation, its Commitment to the Borrower hereunder) shall remain unchanged,
(ii) such Lender shall remain solely responsible to the other parties hereto for
the performance of such obligations, (iii) such Lender shall remain the holder
of any such Notes for all purposes of this Agreement, (iv) the Borrower, the
Agent, and the other Lenders shall continue to deal solely and directly with
such Lender in connection with such Lender's rights and obligations under this
Agreement, and (v) such Lender shall not require the participant's consent to
any matter under this Agreement,



                                      -62-
<PAGE>   68
except for any increase in such Lender's Maximum Commitment, reductions in fees
or interest, or extending the Maturity Date. The Borrower hereby agrees that
participants shall have the same rights under Section 9.4 as a Lender to the
extent of their respective participations.

         Section 9.8 Renewal, Extension or Rearrangement. All provisions of this
Agreement and of any other Loan Documents relating to the Note or other
Indebtedness shall apply with equal force and effect to each and all promissory
notes hereinafter executed which in whole or in part represent a renewal,
extension for any period, increase or rearrangement of any part of the
Indebtedness originally represented by the Notes or of any part of such other
Indebtedness.

         Section 9.9 Waivers. No course of dealing on the part of the Agent, any
Lender, their officers, employees, consultants or agents, nor any failure or
delay by the Agent or any Lender with respect to exercising any right, power or
privilege of the Agent or such Lender under the Note, this Agreement or any
other Loan Document shall operate as a waiver thereof, except as otherwise
provided in Section 9.2 hereof nor shall any single or partial exercise of any
right, power or privilege under any of the Loan Documents preclude any other or
further exercise thereof or the exercise of any other right, power or privilege.
The remedies provided herein are cumulative and not exclusive of any remedies
provided by law.

         Section 9.10 Cumulative Rights. Rights and remedies of the Agent and
each Lender under the Notes, this Agreement and each other Loan Document shall
be cumulative, and the exercise or partial exercise of any such right or remedy
shall not preclude the exercise of any other right or remedy.

         Section 9.11 Singular and Plural. Words used herein in the singular,
where the context so permits, shall be deemed to include the plural and vice
versa. The definitions of words in the singular herein shall apply to such words
when used in the plural where the context so permits and vice versa.

         Section 9.12 Construction. The parties agree that this Agreement, the
Notes and the rights and obligations of the parties in connection with the loan
transactions evidenced in part by this Agreement shall be construed in
accordance with and governed by the laws of the State of New York, without
reference to conflicts of laws rules or principles of the State of New York;
provided that this choice of law provision shall not apply to the Registration
Rights Agreement.

         Section 9.13 Interest. Notwithstanding anything herein or in the other
Loan Documents to the contrary, it is the intention of the parties hereto to
conform strictly to usury laws applicable to this transaction. Accordingly, if
the transactions contemplated hereby would be usurious under applicable law,
then, in that event, notwithstanding anything to the contrary in the Note, this
Agreement or in any other Loan Document or agreement entered into in connection
with or as security for the Note, it is agreed as follows: (a) the aggregate of
all consideration which constitutes interest under law applicable to the Lenders
that is contracted for, taken, reserved, charged or received under the Note,
this Agreement or under any of the other Loan Documents or agreements



                                      -63-
<PAGE>   69
or otherwise in connection with this transaction shall under no circumstances
exceed the maximum amount allowed by such applicable law, and any excess shall
be canceled automatically and, if already paid, shall be credited by the Lenders
on the principal amount of the Indebtedness (or, to the extent that the
principal amount of the Indebtedness shall have been or would thereby be paid in
full, refunded to the Borrower); and (b) in the event that the maturity of the
Notes is accelerated by reason of an election of the Majority Lenders resulting
from any Event of Default under this Agreement or otherwise, or in the event of
any required or permitted prepayment, then such consideration that constitutes
interest under law applicable to this transaction may never include more than
the maximum amount allowed by such applicable law, and (c) excess interest, if
any, provided for in this Agreement or otherwise in connection with the Loans
shall be canceled automatically and, if already paid, shall be credited by the
Lenders on the principal amount of the Indebtedness (or, to the extent that the
principal amount of the Indebtedness shall have been or would thereby be paid in
full, refunded by the Lenders to the Borrower). The right to accelerate the
maturity of the Notes does not include the right to accelerate any interest
which has not otherwise accrued on the date of such acceleration, and no Lender
intends to collect any unearned interest in the event of acceleration. All sums
paid or agreed to be paid to the Lenders for the use, forbearance or detention
of sums included in the Indebtedness shall, to the extent permitted by
applicable law, be amortized, prorated, allocated and spread throughout the full
term of the Notes until payment in full so that the rate or amount of interest
on account of the Indebtedness does not exceed the applicable usury ceiling, if
any. As used in this Section 9.13, the term "applicable law" shall mean the laws
which govern this Agreement as described in Section 9.12 (or the law of any
other jurisdiction whose laws may be mandatorily applicable notwithstanding
other provisions of this Agreement), or law of the United States of America
applicable to the Lenders and the Loans which would permit the Lenders to
contract for, charge, take, reserve or receive a greater amount of interest than
under any other applicable law. If the stated rate of interest under this
Agreement ever exceeds the Highest Lawful Rate, then the outstanding principal
amount of the Loans made hereunder shall bear interest at the Highest Lawful
Rate until the difference between the interest which would have been due at the
stated rates of interest and the amount due at the Highest Lawful Rate (the
"Lost Interest") has been recaptured by the Lenders. If the Loans made hereunder
are repaid in full and the Lost Interest has not been fully recaptured by the
Lenders pursuant to the preceding sentence, then the Loans made hereunder shall
be deemed to have accrued interest at the Highest Lawful Rate since the date the

forth in Sections 2.02 through 2.07 hereof to Superior Indebtedness.

         Section 2.02 Payment Subordination upon Default.

         (a) If any principal, interest or other amounts due in respect of the

and as a result thereof, either the Agent or any Senior Lender shall give the

Agent or any Senior Lender shall give the Subordinated Agent notice (which may

Company or any other Obligor, by set-off or in any other manner, any payment or

evidencing the Subordinated Debt for payment (other than such presentment as may
be necessary to prevent discharge of other liable parties on such instrument).

         Section 2.03 Payments Received or Made in Violation of Subordination
Agreement.

         (a) In the event the Subordinated Agent or any Subordinated Lender
shall receive any payment or distribution on account of the Subordinated Debt
which it is not entitled to receive under the provisions of Section 2.02, the
Subordinated Agent or such Subordinated Lender will hold any amount so received
in trust for the Senior Lenders and will forthwith turn over such payment to the
Agent in the form received by it (together with any necessary endorsement) to be
applied to the Superior Indebtedness. In the event of any failure by the
Subordinated Agent or any Subordinated Lender to make any such endorsement, the
Agent is hereby irrevocably authorized and granted a power of attorney (which is
irrevocable and coupled with interest) to make the same.

         (b) The Borrower, the Parent Company or any Obligor hereby acknowledge
and agree to follow the payment priorities established in Section 2.02. If the
Borrower, the Parent Company or any Obligor shall become aware that an "Event of
Default" has occurred under any Senior Loan Document, then such Person shall
give the Agent, the Senior Lenders and the Subordinated Agent prompt written
notice thereof.

         (c) This Subordination Agreement defines the relative rights of Agent
and the Senior Lenders and the Subordinated Agent and Subordinated Lenders.
Nothing in this Subordination Agreement shall: (i) impair, as between the
Borrower, the Parent Company or any Obligor, the Subordinated Agent and the
Subordinated Lenders, the obligation of the Borrower, the Parent Company and the
Obligors, which are absolute and unconditional, to pay principal of and interest
on the Subordinated Debt in accordance with the terms of the Subordinated Loan
Documents; or (ii) prevent the Subordinated Agent or any Subordinated Lender
from exercising its available remedies, subject to the terms of Section 2.05 and
the rights of the Agent and the Senior Lenders to receive distributions
otherwise payable to the Subordinated Agent and the Subordinated Lenders.

         Section 2.04 Liens Subordinated.

         (a) The Subordinated Agent and the Subordinated Lenders agree that any
Liens, upon the Property of any of the Borrower, the Parent Company or any
Obligor securing payments of the Subordinated Debt are and shall be and remain
inferior and subordinated to any Liens securing payments of the Superior
Indebtedness regardless of whether such encumbrances in favor of the
Subordinated Agent or any Subordinated Lender or the Agent and the Senior
Lenders presently exist or are hereafter created or attached.

         (b) Other than the Liens taken on or about the date hereof for which
the Subordinated Agent has already given notice, the Subordinated Agent and each
Subordinated Lender agree to give the Agent written notice at least fifteen (15)
days prior to the time that it takes a Lien on any Property of the Parent
Company, the Borrower or any Obligor, such notice to specify the Property to be
encumbered by the proposed Lien. If the Subordinated Agent or any Subordinated
Lender shall obtain a Lien on Property of any of the Borrower, the Parent
Company or any Obligor which is not subject to a Lien in favor of the Agent and
the Senior Lenders, then Subordinated Agent and the Subordinated 


                                       4
<PAGE>   96
Lenders agree to exercise their respective rights under the instruments
evidencing such Lien in accordance with the terms of this Subordination
Agreement.

         (c) The Subordinated Agent and the Subordinated Lenders covenant and
agree not to contest or dispute, whether in any proceeding or otherwise, the
validity, enforceability, attachment, priority or perfected status of any Lien
granted in favor of the Agent or any Senior Lender or take any steps or actions,
including the institution of any proceedings, to enjoin or restrain the Agent or
any Senior Lender from the exercise of the remedies afforded them under the
Senior Loan Documents or applicable law.

         (d) If the Borrower, the Parent Company or any Obligor shall, after the
date hereof, acquire any Oil and Gas Properties (or a Person owning Oil and Gas
Properties), then the Subordinated Agent and the Subordinated Lenders covenant
and agree not to take or perfect any Lien against such Properties until the
earlier of (i) 30 days following the date of such acquisition or (ii) the date
the Agent and the Senior Lenders have been granted and have perfected a Lien in
their favor on such Properties.

         Section 2.05 Agreement Not to Pursue Actions.

         (a) If the Agent or the Senior Lenders have given the Subordinated
Agent notice under Section 2.02 that an Event of Default under the Senior Loan
Documents has occurred, the Subordinated Agent and each Subordinated Lender
covenants that it will not, for a period of 180 days following its receipt of
such notice, do any of the following unless the Agent shall also join in such
action or commence a similar action: (i) commence any action or proceeding
against the Borrower, the Parent Company or any Obligor to recover all or any
part of the Subordinated Debt or join with any other creditor in bringing any
proceedings against such Person under any bankruptcy, reorganization,
readjustment of debt, arrangement of debt, receivership, liquidation or
insolvency law or statute of the Federal or any state government or (ii)
foreclose, repossess, sequester or otherwise take steps or institute any action
or proceeding to enforce any Lien, collateral right, judgment or other
encumbrances on any Property of the Borrower, the Parent Company or any Obligor
held by the Subordinated Agent or any Subordinated Lender; provided the
foregoing will not prohibit such presentment as may be necessary to prevent
discharge of other liable parties an instrument.

         (b) If the Subordinated Agent and the Subordinated Lenders shall not
file a proper claim or proof of debt in the form required in any insolvency,
bankruptcy or liquidation proceeding prior to 30 days before the expiration of
the time to file such claim or claims, then the Agent shall have the right to
file an appropriate claim for and on behalf of the Subordinated Agent or such
Subordinated Lender. Nothing herein contained shall be deemed to authorize or
consent to or accept or adopt on behalf of the Subordinated Agent or any
Subordinated Lender any plan of reorganization, arrangement, adjustment or
composition affecting the Subordinated Debt or the rights of the Subordinated
Agent and the Subordinated Lenders, or to authorize the Agent or any Senior
Lender to vote in respect of the claim of the Subordinated Agent or any
Subordinated Lender in any such proceeding.

         Section 2.06 Rights of the Agent and the Senior Lenders. The Agent and
the Senior Lenders may, at any time, and from time to time, without the consent
of or notice to the Subordinated Agent or any Subordinated Lender, without
incurring responsibility to the Subordinated Agent and/or any Subordinated
Lender, without impairing or releasing any of the Agent or the Senior Lenders'
rights or any of the obligations of the Subordinated Agent and the Subordinated
Lenders under this Subordination Agreement:


                                       5
<PAGE>   97
         (a) change the amount, manner, place or terms of payment, or change or
extend for any period the time of payment of, or renew, increase or otherwise
alter the Superior Indebtedness or any Senior Loan Document or any other
instrument or agreement now or hereafter executed or evidencing any of the
Superior Indebtedness in any manner, or enter into or amend in any manner any
other agreement relating to the Superior Indebtedness (including provisions
restricting or further restricting payments of the Subordinated Debt);

         (b) sell, exchange, release or otherwise deal with all or any part of
any Property by whomsoever at any time pledged or mortgaged to secure, howsoever
securing, the Superior Indebtedness;

         (c) release any Person liable in any manner for payment or collection
of the Superior Indebtedness;

         (d) exercise or refrain from exercising any rights against the
Borrower, the Parent Company or any other Obligor or others, including the
Subordinated Agent and the Subordinated Lenders; and

         (e) apply any sums received by the Senior Lenders, paid by any Person
and however realized, to payment of the Superior Indebtedness in such a manner
as the Agent and the Senior Lenders, in their sole discretion, may deem
appropriate.

         Section 2.07 Payments within 90 Days of Default. The obligations under
the Subordinated Loan Documents are revolving in nature and, except as set forth
in Section 2.02, this Subordination Agreement will not prohibit certain payments
made prior to the occurrence of an "Event of Default" under the Senior Loan
Documents. To effect the subordinations intended hereby, the Subordinated Agent
and each Subordinated Lender agree that if (i) it receives a payment in any
manner on account of the Subordinated Debt and within 90 days following its
receipt of such payment the Agent or any Senior Lender shall give a notice under
Section 2.02 that an Event of Default under the Senior Loan Documents has
occurred (other than an Event of Default: (1) for which the Agent or the Senior
Lenders have previously given notice and instituted a payment blockage pursuant
to Section 2.02(b) and (2) which has continued for over 135 days), and (ii) the
Superior Indebtedness has not been paid in full, then such payment will be
treated as if it had been made after the giving of a notice that an Event of
Default under the Senior Loan Documents has occurred and the Subordinated Agent
and the Subordinated Lenders will hold such amount in trust and pay to the
Agent, for its benefit and the benefit of the Senior Lenders, any amount equal
to the amount so received during such 90 day period. The foregoing provisions
shall apply without regard to whether the payments would or would not constitute
preferential payments under the Federal Bankruptcy Code or other applicable
insolvency laws. The Subordinated Agent and the Subordinated Lenders acknowledge
and agree that for purposes of clause (i) above, any subsequent action, failure
to act or any breach of a financial covenant for a period commencing after the
date of the commencement of a payment blockage under Section 2.02(b) that would
give rise to a new Event of Default pursuant to any provision under which a
payment blockage previously existed or was continuing shall constitute a new
Event of Default for purposes of Section 2.02(b) and this Section 2.07. The
Subordinated Agent and the Subordinated Lenders shall be subrogated to the
claims and rights of the Agent and the Senior Lenders to the extent of the
Superior Indebtedness so acquired; provided that the Subordinated Agent and the
Subordinated Lenders shall have no rights until such time as the Superior
Indebtedness shall have been paid in full.

         Section 2.08 Conversions Not Affected. Nothing in this Subordination
Agreement is intended or shall be construed to prevent: (a) the exercise by the
Subordinated Agent or any Subordinated Lender (or an affiliate of it) of
conversion rights contained in the Subordinated Loan Documents, (b) the receipt
by the Subordinated Agent or any Subordinated Lender of shares of stock and debt
securities that are subordinated to all Superior Indebtedness of the Borrower,
the Parent Company or an Obligor to at least the same extent as the Subordinated
Debt, and (c) the presentment of an instrument to prevent discharge of other
liable parties on such instrument.

                                   ARTICLE III
                    Representations, Warranties and Covenants

         Section 3.01 Representations of Subordinated Agent and Subordinated
Lenders. The Subordinated Agent and each Subordinated Lender represent and
warrant that:

         (a) neither the execution nor delivery of this Subordination Agreement
nor fulfillment of or compliance with the terms and provisions hereof will

or constitute a default under, any agreement or instrument which it is now
subject to;

         (b) it has all requisite authority to execute, deliver and perform its
obligations under this Subordination Agreement; and

         Section 3.02 Covenants. The Subordinated Agent and each Subordinated
Lender covenant that so long as any of the Superior Indebtedness remains
outstanding and until the termination of the "Aggregate Commitments" (as defined

         (a) cause all Subordinated Debt to be evidenced by a note, debenture or
other instrument evidencing the Subordinated Debt;

         (b) cause any such note, debenture, or instrument evidencing the

         (c) not assign or transfer to others the Subordinated Debt or any claim
it has or may have against the Borrower, the Parent Company or any other Obligor

or interest on any of the Subordinated Debt except in accordance with the terms
of this Subordination Agreement;

         (e) not amend, supplement or otherwise modify the terms of the
Subordinated Debt without the express written consent of the Agent and the
Senior Lenders, which consent will not be unreasonably withheld, which has the
effect of (i) increasing the "Commitment" under the Subordinated 


                                       7
<PAGE>   99
Loan Agreement (provided that the foregoing shall not affect the Subordinated
Agent and the Subordinated Lenders' ability to increase its borrowing base),
(ii) increasing the rate of interest charged on the Subordinated Debt (provided
that the foregoing shall not prohibit changes in the rate of interest
contemplated by the terms of the Subordinated Loan Agreement), (iii) changes the
fees charged under the Subordinated Loan Documents, or (iv) modifies or deletes
the terms of Section 9.22 of the Subordinated Loan Agreement or the
subordination language contained in the note issued pursuant to the Subordinated
Loan Agreement;

the Senior Lenders a true and complete copy of any material notices or
communications either received or delivered to or from the Parent Company, the
Borrower or any Obligor with respect to the Subordinated Debt; and

         (g) execute any and all other instruments necessary as reasonably
required by the Agent or the Senior Lenders to effect the subordinations
intended hereby.

                                   ARTICLE IV
                                  Miscellaneous

         Section 4.01 Acceptance by the Agent and the Senior Lenders. The
foregoing subordination provisions are, and are intended to be, an inducement
and a consideration to the Agent and each Senior Lender, whether such Senior
Lender's Superior Indebtedness is created or acquired before or after the
issuance of Subordinated Debt, to acquire and continue to hold, or to continue
to hold, such Superior Indebtedness and each such Senior Lender shall be deemed
conclusively to have relied on such subordination provisions in acquiring and
continuing to hold, or in continuing to hold, such Superior Indebtedness. Notice
of acceptance of this Subordination Agreement is waived, acceptance on the part
of the Agent and the Senior Lenders being conclusively presumed by their request
for this Subordination Agreement and delivery of the same to them.

Subordination Agreement may be assigned by the Agent and the Senior Lenders in
connection with any assignment or transfer of the Superior Indebtedness.

delay by the Agent and the Senior Lenders in exercising any right, power or
remedy hereunder shall not be deemed a waiver of any obligation of the Borrower,
the Parent Company or any Obligor or the Subordinated Agent or any Subordinated
Lender, or of any right, power or remedy of the Agent and the Senior Lenders;
and no partial exercise of any right, power or remedy shall preclude any other
or further exercise thereof. The Subordinated Agent and the Subordinated Lenders
hereby agree that if the Agent and/or any Senior Lender agrees to a waiver of
any provision hereunder, or an exchange of or release of collateral, or the
addition or release of any Person as an Obligor, any such action shall not
constitute a waiver of any of the Agent's and/or any Senior Lender's other
rights or of the Subordinated Agent's or any Subordinated Lender's obligations
hereunder. This Subordination Agreement may be amended only by an instrument in
writing executed jointly by Subordinated Agent and the Agent and may be
supplemented only by documents delivered or to be delivered in accordance with
the express terms hereof.

         Section 4.05 Parties to the Agreement. The provisions of this

the relative rights of the Subordinated Agent, the Subordinated Lenders, the

Senior Lenders, the Subordinated Agent and the Subordinated Lenders; and may not
be relied upon or enforced by any party other than the Agent, the Senior
Lenders, the Subordinated Agent or the Subordinated Lenders.

         Section 4.06 Reinstatement. To the extent that any payments on the
Superior Indebtedness or proceeds of any collateral are subsequently
invalidated, declared to be fraudulent or preferential, set aside or required to
be repaid by the Agent or any Senior Lender to a trustee, debtor in possession,
receiver or other Person under any bankruptcy law, common law or equitable
cause, then to such extent, obligations hereunder with respect to the Superior
Indebtedness so satisfied shall be revived and continue as if such payment or
proceeds had not been received and the Agent's and the Senior Lenders' Liens,
interests, rights, powers and remedies under the Senior Loan Documents and this
Subordination Agreement shall continue in full force and effect. In such event,
each Senior Loan Document and this Subordination Agreement shall be
automatically reinstated and the Borrower, the Parent Company, the Obligors, the
Subordinated Agent and the Subordinated Lenders shall take such action as may be
reasonably requested by the Agent and the Senior Lenders to effect such
reinstatement.

         Section 4.07 Governing Law. THIS SUBORDINATION AGREEMENT SHALL BE
GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF TEXAS.

                                    GUARANTY
                                (Parent Company)


         This Guaranty dated as of December 29, 1997 ("Agreement"), is made by
Queen Sand Resources, Inc., a Delaware corporation ("Guarantor"), in favor of
Enron Capital & Trade Resources Corp., a Delaware corporation, in its capacity
as agent for the lenders described below ("Agent").

                                  INTRODUCTION

         This Agreement is given in connection with the Subordinated Revolving
Credit Loan Agreement dated as of December 29, 1997 (as modified from time to
time, the "Loan Agreement"), among Queen Sand Resources, Inc., a Nevada
corporation ("Borrower"), the lenders who are or may become party thereto, and
the Agent, the defined terms of which are used herein unless otherwise defined
herein. It is a condition precedent to the effectiveness of the Loan Agreement
that the Guarantor executes and delivers this Agreement to the Agent. The
Borrower is a Subsidiary of the Guarantor. The Guarantor expects that, as a
result of its ownership of the Borrower, it will obtain substantial benefit from
the extensions of credit expected to be made to the Borrower under the Loan
Agreement.

         Therefore, to induce the Agent and the Lenders to enter into the Loan
Agreement, the Guarantor agrees with the Agent as follows:

Section 1.        Guaranty.

         1.1 The Guarantor irrevocably guarantees to the Agent the full payment
when due of (a) all principal, interest, fees, reimbursements, indemnifications,
and other amounts now or hereafter owed by the Borrower to the Agent or any
Lender (and with respect to the Interest Hedge Agreements, any Affiliates of any
Lender) under the terms of the Loan Agreement and the other Loan Documents,
including amounts owed under the terms of the Loan Agreement and the other Loan
Documents for which the Borrower has obtained relief under bankruptcy or other
laws providing for relief from creditors, and (b) any increases, extensions, and
rearrangements of the foregoing obligations under any amendments, supplements,
and other modifications of the documents and agreements creating the foregoing
obligations (collectively, the "Guaranteed Obligations"). This is a guaranty of
payment and not merely a guaranty of collection, and the Guarantor is liable as
a primary obligor. If any of the Guaranteed Obligations are not punctually paid
when due, whether by maturity, acceleration, or otherwise, and the Agent shall
notify the Guarantor of such default and make demand for payment hereunder, the
Guarantor shall immediately pay to the Agent the full amount of the Guaranteed
Obligations which are due and payable. The Guarantor shall make each payment to
the Agent in U.S. Dollars in immediately available funds as directed by the
Agent. The Agent is hereby authorized at any time following any demand for
payment hereunder to set off and apply any indebtedness owed by the Agent to the
Guarantor against any and all of the obligations of the Guarantor under this
Agreement. The Agent agrees to promptly notify the Guarantor after any such
setoff and application, but the failure to give such notice shall not affect the
validity of such setoff and application.

         1.2 This Agreement is subordinate to the Senior Debt in accordance with
the terms of the Subordination Agreement.

Section 2.        Guaranty Absolute.

         2.1 This Agreement shall be deemed accepted by the Agent upon receipt,
and the obligations of the Guarantor under this Agreement are effective
immediately and are continuing and cover all Guaranteed Obligations arising
prior to and after the date hereof. This Agreement may not be revoked by the
Guarantor and shall continue to be effective with respect to Guaranteed
Obligations arising or created after any attempted revocation by the Guarantor.

         2.2 The Guarantor guarantees that the Guaranteed Obligations will be
paid strictly in accordance with the terms of the Loan Agreement and the other
Loan Documents, regardless of any law, regulation, or order now or hereafter in
effect in any jurisdiction affecting any of such terms or the rights of the
Agent or the Lenders with respect thereto. The Guarantor agrees that the
Guarantor's obligations under this Agreement shall not be released, diminished,
or impaired by, and waives any rights which the Guarantor might otherwise have
which relate to:

                  (a) Any lack of validity or enforceability of the Guaranteed
Obligations, any Loan Document, or any other agreement or instrument relating
thereto; any increase, reduction, extension, or rearrangement of the Guaranteed
Obligations; any amendment, supplement, or other modification of the Loan
Documents; any waiver or consent granted under the Loan Documents, including
waivers of the payment and performance of the Guaranteed Obligations; or any
sale, assignment, delegation, or other transfer of the Guaranteed Obligations or
the Loan Documents;

                  (b) Any grant of any security or support for the Guaranteed
Obligations or any impairment of any security or support for the Guaranteed
Obligations, including any full or partial release, exchange, subordination, or
waste of any collateral for the Guaranteed Obligations or any full or partial
release of the Borrower, the Guarantor, or any other Person liable for the
payment or performance of the Guaranteed Obligations; any change in the
organization or structure of the Borrower, the Guarantor, or any other Person
liable for the payment or performance of the Guaranteed Obligations; or the
insolvency, bankruptcy, liquidation, or dissolution of the Borrower, the
Guarantor, or any other Person liable for the payment or performance of the
Guaranteed Obligations;

                  (c) The manner of applying payments on the Guaranteed
Obligations or the proceeds of any security or support for the Guaranteed
Obligations against the Guaranteed Obligations;

                  (d) The failure to give notice of the occurrence of any of the
events or actions referred to in this Section 2.2, notice of any default or
event of default, however denominated, under the Loan Documents, notice of
intent to demand, notice of demand, notice of presentment for payment, notice of
nonpayment, notice of intent to protest, notice of protest, notice of grace,
notice of dishonor, notice of intent to accelerate, notice of acceleration,
notice of bringing of action to enforce the payment or performance of the
Guaranteed Obligations, notice of any sale or foreclosure

of any collateral for the Guaranteed Obligations, notice of any transfer of the
Guaranteed Obligations, notice of the financial condition of or other
circumstances regarding the Borrower, the Guarantor, or any other Person liable
for the Guaranteed Obligations, or any other notice of any kind relating to the
Guaranteed Obligations (and the parties intend that no Guarantor by execution of
this Agreement shall be considered a "Debtor" as defined in Section 9.105 of the
UCC for the purpose of notices required to be given to a Debtor thereunder); or

                  (e) Any other action taken or omitted which affects the
Guaranteed Obligations, whether or not such action or omission prejudices the
Guarantor or increases the likelihood that the Guarantor will be required to pay
the Guaranteed Obligations pursuant to the terms hereof--it is the unambiguous
and unequivocal intention of the Guarantor that the Guarantor shall be obligated
to pay the Guaranteed Obligations when due, notwithstanding any occurrence,
circumstance, event, action, or omission whatsoever, whether contemplated or
uncontemplated, and whether or not particularly described herein.

         2.3 This Agreement shall continue to be effective or be reinstated, as
the case may be, if any payment on the Guaranteed Obligations must be refunded
for any reason including any bankruptcy proceeding. In the event that the Agent
or any Lender must refund any payment received against the Guaranteed
Obligations, any prior release from the terms of this Agreement given to the
Guarantor by the Agent shall be without effect, and this Agreement shall be
reinstated in full force and effect. It is the intention of the Guarantor that
the Guarantor's obligations hereunder shall not be discharged except by final
payment of the Guaranteed Obligations.

Section 3.        Unimpaired Collection.

         3.1 There are no conditions precedent to the enforcement of this
Agreement, except as expressly contained herein. It shall not be necessary for
the Agent, in order to enforce payment by the Guarantor under this Agreement, to
show any proof of the Borrower's default, to exhaust the Agent's remedies
against the Borrower, the Guarantor, or any other Person liable for the payment
or performance of the Guaranteed Obligations, to enforce any security or support
for the payment or performance of the Guaranteed Obligations, or to enforce any
other means of obtaining payment or performance of the Guaranteed Obligations.
The Guarantor waives any statutory or common law procedural or substantive
rights related to the foregoing. Neither the Agent nor any Lender shall be
required to mitigate damages or take any other action to reduce, collect, or
enforce the Guaranteed Obligations.

         3.2 With respect to the Guarantor, all Subordinated Obligations of the
Guarantor (as defined below) shall be subordinate and junior in right of payment
and collection to the payment and collection in full of all Guaranteed
Obligations as described below:

                  (a) As used herein, the term "Subordinated Obligations" for
the Guarantor means: (i) all present and future indebtedness, liabilities, and
obligations of any kind owed by the Borrower, any other Guarantor (as defined in
the Loan Agreement), or any other Person liable for the payment or performance
of the Guaranteed Obligations to the Guarantor, including (A) debt obligations,
equity obligations, and other contractual obligations requiring payments of any
kind to be made to



                                        3

<PAGE>   4



the Guarantor and including (B) any right of subrogation (including any
statutory rights of subrogation under Section 509 of the Bankruptcy Code, 11
U.S.C. Section 509, or under state statutes), contribution, indemnification,
reimbursement, exoneration, or any right to participate in any claim or remedy
of the Agent against the Borrower, the Guarantor, or any Person liable for the
payment or performance of the Guaranteed Obligations, or any collateral which
the Agent now has or may acquire, and (ii) any increases, extensions, and
rearrangements of the foregoing obligations under any amendments, supplements,
and other modifications of the documents and agreements creating the foregoing
obligations.

                  (b) Until all Guaranteed Obligations have been irrevocably
paid in full (and therefore the payment thereof is no longer subject to being
set aside or returned under the law), the Guarantor agrees not to take any
action to enforce payment of the Subordinated Obligations of the Guarantor, but
this standstill is not intended as a permanent waiver of the subrogation,
contribution, indemnification, reimbursement, exoneration, participation, or
other rights of the Guarantor.

                  (c) Upon any receivership, insolvency proceeding, bankruptcy
proceeding, assignment for the benefit of creditors, reorganization, arrangement
with creditors, sale of assets for creditors, dissolution, liquidation, or
marshaling of the assets of the Borrower, the Guarantor, or any other Person
liable for the payment or performance of the Guaranteed Obligations, (i) all
amounts due with respect to the Guaranteed Obligations shall be paid in full
before the Guarantor shall be entitled to collect or receive any payment with
respect to the Subordinated Obligations of the Guarantor, and (ii) all payments
to which the Guarantor would be entitled to collect or receive on the
Subordinated Obligations of the Guarantor shall be paid over to the Agent for
application to the Guaranteed Obligations.

                  (d) Following notice from the Agent to the Borrower that an
Event of Default exists and that no further payments shall be made on the
Subordinated Obligations of the Guarantor, all amounts due with respect to the
Guaranteed Obligations shall be paid in full before the Guarantor shall be
entitled to collect or receive any payment with respect to the Subordinated
Obligations of the Guarantor.

                  (e) Any lien, security interest, or assignment securing the
repayment of the Subordinated Obligations of the Guarantor shall be fully
subordinate to any lien, security interest, or assignment in favor of the Agent
or any Lender which secures the Guaranteed Obligations. At the request of the
Agent, the Guarantor will take any and all steps necessary to fully evidence the
subordination granted hereunder, including amending or terminating financing
statements and executing and recording subordinations of liens.

                  (f) This is an absolute and irrevocable agreement of
subordination and the Agent may, without notice to the Guarantor, take any
action described in Section 2.2 without impairing or releasing the obligations
of the Guarantor hereunder.

                  (g) Except for assignments made pursuant to guaranties of the
Senior Debt, the Guarantor shall not assign or otherwise transfer to any other
Person any interest in the Subordinated Obligations of the Guarantor without the
prior written permission of the Lender and except for



                                        4

<PAGE>   5



assignments made pursuant to guaranties of the Senior Debt, unless the Guarantor
causes the assignee or other transferee to execute and deliver to the Agent a
subordination agreement in substantially the form of the subordination
provisions in this Agreement.

                  (h) If any amount shall be paid to the Guarantor in violation
of this Section 3.2, such amount shall be held in trust for the benefit of the
Agent and immediately turned over to the Agent, with any necessary endorsement,
to be applied to the Guaranteed Obligations.

Section 4.        Miscellaneous.

         4.1 The Guarantor hereby affirms and shall comply with the
representations, warranties, and covenants made by the Borrower in the Loan
Agreement to the extent that such representations, warranties, and covenants are
applicable to the Guarantor, including all of the covenants in Articles 4 and 5
of the Loan Agreement.

         4.2 The Guarantor shall take all actions necessary to comply with the
Borrower's obligations under Section 2.11 of the Loan Agreement and to
effectuate any exchange made thereunder. The Guarantor shall at all times
reserve and keep available, free from preemptive rights, as part of the
authorized but unissued common stock of the Guarantor ("Parent Company Common
Stock"), solely for the purpose of issuance upon an exchange pursuant to Section
2.11 of the Loan Agreement, such number of shares of Parent Company Common Stock
as shall then be issuable upon the exchange of the entire amount of the
outstanding principal balance of the Note and accrued but unpaid interest
thereon. The Guarantor covenants that all shares of Parent Company Common Stock
which shall be so issuable shall, upon issuance, be duly and validly issued,
fully paid and nonassessable. The Guarantor shall from time to time, in
accordance with applicable law, increase the authorized amount of Parent Company
Common Stock if at any time the authorized amount of Parent Company Common Stock
remaining unissued shall not be sufficient to permit the exchange of the entire
amount of the outstanding principal balance of the Note and accrued but unpaid
interest thereon. The Guarantor covenants that it shall not permit the par value
of the Parent Company Common Stock to be increased from $0.0015 per share. The
issuance of certificates representing shares of Parent Company Common Stock upon
an exchange pursuant to Section 2.11 of the Loan Agreement shall be made without
charge to the Lenders for any tax in respect of the issuance of such
certificates, and such certificates shall be issued in the name of, or in such
names as may be directed by, the Agent; provided that in no event shall the
Guarantor be required to pay or reimburse any Lender or the holder of any such
certificate for any income tax payable by such Lender or such holder as a result
of such issuance. The Guarantor agrees that any Parent Company Common Stock
issued pursuant to Section 2.11 of the Loan Agreement shall be "Registrable
Securities" for the purposes of the Registration Rights Agreement.

         4.3 The Guarantor agrees that this Agreement shall be governed by the
laws of the State of New York. If any provision in this Agreement is held to be
unenforceable, such provision shall be severed and the remaining provisions
shall remain in full force and effect. All representations, warranties, and
covenants of the Guarantor in this Agreement shall survive the execution of this
Agreement and any other contract or agreement. If a due date for an amount
payable is not specified in this Agreement, the due date shall be the date on
which the Agent demands payment therefor.

The Agent's and the Lenders' remedies under this Agreement and the Loan
Documents to which the Guarantor is a party shall be cumulative, and no delay in
enforcing this Agreement and the Loan Documents to which the Guarantor is a
party shall act as a waiver of the Agent's or any Lenders' rights thereunder.
The provisions of this Agreement may be waived or amended only in a writing
signed by the party against whom enforcement is sought. This Agreement shall
bind and inure to the benefit of the Guarantor and the Lender and their
respective successors and assigns. The Guarantor may not assign its rights or
delegate its duties under this Agreement. The Agent and the Lenders may assign
their rights and delegate its duties under this Agreement in accordance with the
terms of the Loan Agreement. This Agreement may be executed in multiple
counterparts each of which shall constitute one and the same agreement. Unless
otherwise specified, all notices and other communications between the Guarantor
and the Agent provided for in this Agreement and the Loan Documents to which the
Guarantor is a party shall be in writing and shall be mailed by first class or
express mail, postage prepaid, or sent by telex, telegram, telecopy or other
similar form of rapid transmission, or personally delivered to the receiving
party. Any communication so addressed and mailed shall be deemed to be given
when so mailed and any notice so sent by rapid transmission shall be deemed to
be given when receipt of such transmission is acknowledged or confirmed, and any
communication so delivered in person shall be deemed to be given when receipted

                                    GUARANTY
                                 (Subsidiaries)


         This Guaranty dated as of December 29, 1997 ("Agreement"), is made by
the undersigned subsidiaries of Queen Sand Resources, Inc., a Nevada corporation
(each a "Guarantor"), in favor of Enron Capital & Trade Resources Corp., a
Delaware corporation in its capacity as agent for the lenders described below
("Agent").

                                  INTRODUCTION

         This Agreement is given in connection with the Subordinated Revolving
Credit Loan Agreement dated as of December 29, 1997 (as modified from time to
time, the "Loan Agreement"), among Queen Sand Resources, Inc., a Nevada
corporation ("Borrower"), the lenders who are or may become party thereto, and
the Agent, the defined terms of which are used herein unless otherwise defined
herein. It is a condition precedent to the effectiveness of the Loan Agreement
that the Guarantors execute and deliver this Agreement to the Agent. Because
each Guarantor is a Subsidiary of the Borrower, each Guarantor receives and
expects to continue to receive financial and management support from the
Borrower, and thus, each Guarantor will obtain substantial benefit from the
extensions of credit expected to be made to the Borrower under the Loan
Agreement.

         Therefore, to induce the Agent and the Lenders to enter into the Loan
Agreement, the Guarantors jointly and severally agree with the Agent as follows:

Section 1.        Guaranty.

         1.1 The Guarantors irrevocably and jointly and severally guarantee to
the Agent the full payment when due of (a) all principal, interest, fees,
reimbursements, indemnifications, and other amounts now or hereafter owed by the
Borrower to the Agent or any Lender (and with respect to the Interest Hedge
Agreements, any Affiliates of any Lender) under the terms of the Loan Agreement
and the other Loan Documents, including amounts owed under the terms of the Loan
Agreement and the other Loan Documents for which the Borrower has obtained
relief under bankruptcy or other laws providing for relief from creditors, and
(b) any increases, extensions, and rearrangements of the foregoing obligations
under any amendments, supplements, and other modifications of the documents and
agreements creating the foregoing obligations (collectively, the "Guaranteed
Obligations"). This is a guaranty of payment and not merely a guaranty of
collection, and each Guarantor is liable as a primary obligor. If any of the
Guaranteed Obligations are not punctually paid when due, whether by maturity,
acceleration, or otherwise, and the Agent shall notify any Guarantor of such
default and make demand for payment hereunder, such Guarantor shall immediately
pay to the Agent the full amount of the Guaranteed Obligations which are due and
payable. Each Guarantor shall make each payment to the Agent in U.S. Dollars in
immediately available funds as directed by the Agent. The Agent is hereby
authorized at any time following any demand for payment hereunder to set off and
apply any indebtedness owed by the Agent to any Guarantor against any and all of
the obligations of such Guarantor under this Agreement. The Agent





<PAGE>   2



agrees to promptly notify such Guarantor after any such setoff and application,
but the failure to give such notice shall not affect the validity of such setoff
and application.

         1.2 This Agreement is subordinate to the Senior Debt in accordance with
the terms of the Subordination Agreement.

Section 2.        Guaranty Absolute.

         2.1 This Agreement shall be deemed accepted by the Agent upon receipt,
and the obligations of the Guarantors under this Agreement are effective
immediately and are continuing and cover all Guaranteed Obligations arising
prior to and after the date hereof. This Agreement may not be revoked by any
Guarantor and shall continue to be effective with respect to Guaranteed
Obligations arising or created after any attempted revocation by any Guarantor.

         2.2 Each Guarantor guarantees that the Guaranteed Obligations will be
paid strictly in accordance with the terms of the Loan Agreement and the other
Loan Documents, regardless of any law, regulation, or order now or hereafter in
effect in any jurisdiction affecting any of such terms or the rights of the
Agent with respect thereto. Each Guarantor agrees that such Guarantor's
obligations under this Agreement shall not be released, diminished, or impaired
by, and waives any rights which such Guarantor might otherwise have which relate
to:

                  (a) Any lack of validity or enforceability of the Guaranteed
Obligations, any Loan Document, or any other agreement or instrument relating
thereto; any increase, reduction, extension, or rearrangement of the Guaranteed
Obligations; any amendment, supplement, or other modification of the Loan
Documents; any waiver or consent granted under the Loan Documents, including
waivers of the payment and performance of the Guaranteed Obligations; or any
sale, assignment, delegation, or other transfer of the Guaranteed Obligations or
the Loan Documents;

                  (b) Any grant of any security or support for the Guaranteed
Obligations or any impairment of any security or support for the Guaranteed
Obligations, including any full or partial release, exchange, subordination, or
waste of any collateral for the Guaranteed Obligations or any full or partial
release of the Borrower, any Guarantor, or any other Person liable for the
payment or performance of the Guaranteed Obligations; any change in the
organization or structure of the Borrower, any Guarantor, or any other Person
liable for the payment or performance of the Guaranteed Obligations; or the
insolvency, bankruptcy, liquidation, or dissolution of the Borrower, any
Guarantor, or any other Person liable for the payment or performance of the
Guaranteed Obligations;

                  (c) The manner of applying payments on the Guaranteed
Obligations or the proceeds of any security or support for the Guaranteed
Obligations against the Guaranteed Obligations;

                  (d) The failure to give notice of the occurrence of any of the
events or actions referred to in this Section 2.2, notice of any default or
event of default, however denominated, under the Loan Documents, notice of
intent to demand, notice of demand, notice of presentment for



                                        2

<PAGE>   3



payment, notice of nonpayment, notice of intent to protest, notice of protest,
notice of grace, notice of dishonor, notice of intent to accelerate, notice of
acceleration, notice of bringing of action to enforce the payment or performance
of the Guaranteed Obligations, notice of any sale or foreclosure of any
collateral for the Guaranteed Obligations, notice of any transfer of the
Guaranteed Obligations, notice of the financial condition of or other
circumstances regarding the Borrower, any Guarantor, or any other Person liable
for the Guaranteed Obligations, or any other notice of any kind relating to the
Guaranteed Obligations (and the parties intend that no Guarantor by execution of
this Agreement shall be considered a "Debtor" as defined in Section 9.105 of the
UCC for the purpose of notices required to be given to a Debtor thereunder); or

                  (e) Any other action taken or omitted which affects the
Guaranteed Obligations, whether or not such action or omission prejudices any
Guarantor or increases the likelihood that any Guarantor will be required to pay
the Guaranteed Obligations pursuant to the terms hereof--it is the unambiguous
and unequivocal intention of each Guarantor that such Guarantor shall be
obligated to pay the Guaranteed Obligations when due, notwithstanding any
occurrence, circumstance, event, action, or omission whatsoever, whether
contemplated or uncontemplated, and whether or not particularly described
herein.

         2.3 This Agreement shall continue to be effective or be reinstated, as
the case may be, if any payment on the Guaranteed Obligations must be refunded
for any reason including any bankruptcy proceeding. In the event that the Agent
or any Lender must refund any payment received against the Guaranteed
Obligations, any prior release from the terms of this Agreement given to any
Guarantor by the Agent shall be without effect, and this Agreement shall be
reinstated in full force and effect. It is the intention of each Guarantor that
such Guarantor's obligations hereunder shall not be discharged except by final
payment of the Guaranteed Obligations.

         2.4      (a) Each Guarantor is a Subsidiary of the Borrower and
receives and, because of its ownership by the Borrower, expects to continue to
receive business opportunities, financial support, and management support from
the Borrower. Each Guarantor has agreed to enter into this Agreement so that the
Borrower can receive the benefits of the Guaranteed Obligations and continue to
provide these services to such Guarantor.

                  (b) In consummating the transactions contemplated by the Loan
Documents, no Guarantor intends to disturb, delay, hinder, or defraud either
present or future creditors of such Guarantor. Each Guarantor is familiar with,
and has independently reviewed books and records regarding, the financial
condition of the Borrower and is familiar with the value of the security and
support for the payment and performance of the Guaranteed Obligations. Based
upon such examination, and taking into account the fairly discounted value of
such Guarantor's contingent obligations under this Agreement and the value of
the subrogation and contribution claims such Guarantor could make in connection
with this Agreement, and assuming each of the transactions contemplated by the
Loan Documents is consummated and the Borrower makes full use of the credit
facilities thereunder, the present realizable fair market value of the assets of
such Guarantor exceeds the total obligations of such Guarantor, and such
Guarantor is able to realize upon its assets and pay its obligations as such
obligations mature in the normal course of business.




                                        3

<PAGE>   4



                  (c) If notwithstanding the foregoing it is judicially
determined with respect to any Guarantor that entering into this Agreement would
violate Section 548 of the United States Bankruptcy Code or any comparable
provisions of any state law, then such Guarantor shall be liable under this
Guaranty only for amounts aggregating up to the largest amount that would not
render such Guarantor's obligations hereunder subject to avoidance under Section
548 of the United States Bankruptcy Code or any comparable provisions of any
state law.

                  (d) Each Guarantor agrees that each Guarantor shall have
rights of contribution and subrogation against each other Guarantor with respect
to any payments made in connection with the Guaranteed Obligations.

Section 3.        Unimpaired Collection.

         3.1 There are no conditions precedent to the enforcement of this
Agreement, except as expressly contained herein. It shall not be necessary for
the Agent, in order to enforce payment by any Guarantor under this Agreement, to
show any proof of the Borrower's default, to exhaust the Agent's remedies
against the Borrower, any Guarantor, or any other Person liable for the payment
or performance of the Guaranteed Obligations, to enforce any security or support
for the payment or performance of the Guaranteed Obligations, or to enforce any
other means of obtaining payment or performance of the Guaranteed Obligations.
Each Guarantor waives any statutory or common law procedural or substantive
rights related to the foregoing. Neither the Agent nor any Lender shall be
required to mitigate damages or take any other action to reduce, collect, or
enforce the Guaranteed Obligations.

         3.2 With respect to each Guarantor, all Subordinated Obligations of
such Guarantor (as defined below) shall be subordinate and junior in right of
payment and collection to the payment and collection in full of all Guaranteed
Obligations as described below:

                  (a) As used herein, the term "Subordinated Obligations" for
such Guarantor means: (i) all present and future indebtedness, liabilities, and
obligations of any kind owed by the Borrower, any other Guarantor, or any other
Person liable for the payment or performance of the Guaranteed Obligations to
such Guarantor, including (A) debt obligations, equity obligations, and other
contractual obligations requiring payments of any kind to be made to such
Guarantor and including (B) any right of subrogation (including any statutory
rights of subrogation under Section 509 of the Bankruptcy Code, 11 U.S.C.
Section 509, or under state statutes), contribution, indemnification,
reimbursement, exoneration, or any right to participate in any claim or remedy
of the Agent against the Borrower, any Guarantor, or any Person liable for the
payment or performance of the Guaranteed Obligations, or any collateral which
the Agent now has or may acquire, and (ii) any increases, extensions, and
rearrangements of the foregoing obligations under any amendments, supplements,
and other modifications of the documents and agreements creating the foregoing
obligations.

                  (b) Until all Guaranteed Obligations have been irrevocably
paid in full (and therefore the payment thereof is no longer subject to being
set aside or returned under the law), such Guarantor agrees not to take any
action to enforce payment of the Subordinated Obligations of such



                                        4

<PAGE>   5



Guarantor, but this standstill is not intended as a permanent waiver of the
subrogation, contribution, indemnification, reimbursement, exoneration,
participation, or other rights of such Guarantor.

                  (c) Upon any receivership, insolvency proceeding, bankruptcy
proceeding, assignment for the benefit of creditors, reorganization, arrangement
with creditors, sale of assets for creditors, dissolution, liquidation, or
marshaling of the assets of the Borrower, any Guarantor, or any other Person
liable for the payment or performance of the Guaranteed Obligations, (i) all
amounts due with respect to the Guaranteed Obligations shall be paid in full
before such Guarantor shall be entitled to collect or receive any payment with
respect to the Subordinated Obligations of such Guarantor, and (ii) all payments
to which such Guarantor would be entitled to collect or receive on the
Subordinated Obligations of such Guarantor shall be paid over to the Agent for
application to the Guaranteed Obligations.

                  (d) Following notice from the Agent to the Borrower that an
Event of Default exists and that no further payments shall be made on the
Subordinated Obligations of such Guarantor, all amounts due with respect to the
Guaranteed Obligations shall be paid in full before such Guarantor shall be
entitled to collect or receive any payment with respect to the Subordinated
Obligations of such Guarantor.

                  (e) Any lien, security interest, or assignment securing the
repayment of the Subordinated Obligations of such Guarantor shall be fully
subordinate to any lien, security interest, or assignment in favor of the Agent
or any Lender which secures the Guaranteed Obligations. At the request of the
Agent, such Guarantor will take any and all steps necessary to fully evidence
the subordination granted hereunder, including amending or terminating financing
statements and executing and recording subordinations of liens.

                  (f) This is an absolute and irrevocable agreement of
subordination and the Agent may, without notice to such Guarantor, take any
action described in Section 2.2 without impairing or releasing the obligations
of such Guarantor hereunder.

                  (g) Except for assignments made pursuant to guaranties of the
Senior Debt, such Guarantor shall not assign or otherwise transfer to any other
Person any interest in the Subordinated Obligations of such Guarantor without
the prior written permission of the Agent and except for assignments made
pursuant to guaranties of the Senior Debt, unless such Guarantor causes the
assignee or other transferee to execute and deliver to the Agent a subordination
agreement in sub stantially the form of the subordination provisions in this
Agreement.

                  (h) If any amount shall be paid to such Guarantor in violation
of this Section 3.2, such amount shall be held in trust for the benefit of the
Agent and immediately turned over to the Agent, with any necessary endorsement,
to be applied to the Guaranteed Obligations.

Section 4.        Miscellaneous.

         4.1 Each Guarantor hereby affirms and shall comply with the
representations, warranties, and covenants made by the Borrower in the Loan
Agreement to the extent that such representations,



                                        5

<PAGE>   6



warranties, and covenants are applicable to such Guarantor, including all of the
covenants in Articles 4 and 5 of the Loan Agreement.

         4.2 Each Guarantor agrees that this Agreement shall be governed by the
laws of the State of New York. If any provision in this Agreement is held to be
unenforceable, such provision shall be severed and the remaining provisions
shall remain in full force and effect. All representations, warranties, and
covenants of any Guarantor in this Agreement shall survive the execution of this
Agreement and any other contract or agreement. If a due date for an amount
payable is not specified in this Agreement, the due date shall be the date on
which the Agent demands payment therefor. The Agent's and the Lenders' remedies
under this Agreement and the Loan Documents to which any Guarantor is a party
shall be cumulative, and no delay in enforcing this Agreement and the Loan
Documents to which such Guarantor is a party shall act as a waiver of the
Agent's or any Lenders' rights thereunder. The provisions of this Agreement may
be waived or amended only in a writing signed by the party against whom
enforcement is sought. This Agreement shall bind and inure to the benefit of
each Guarantor and the Lender and their respective successors and assigns. No
Guarantor may assign its rights or delegate its duties under this Agreement. The
Agent and the Lenders may assign their rights and delegate its duties under this
Agreement in accordance with the terms of the Loan Agreement. This Agreement may
be executed in multiple counterparts each of which shall constitute one and the
same agreement. Unless otherwise specified, all notices and other communications
between such Guarantor and the Agent provided for in this Agreement and the Loan
Documents to which such Guarantor is a party shall be in writing and shall be
mailed by first class or express mail, postage prepaid, or sent by telex,
telegram, telecopy or other similar form of rapid transmission, or personally
delivered to the receiving party. Any communication so addressed and mailed
shall be deemed to be given when so mailed and any notice so sent by rapid
transmission shall be deemed to be given when receipt of such transmission is
acknowledged or confirmed, and any communication so delivered in person shall be
deemed to be given when receipted for by, or actually received by, an authorized
officer of the Borrower or the Agent, as the case may be. All such
communications shall be mailed, sent or delivered,

                          REGISTRATION RIGHTS AGREEMENT

                  This Registration Rights Agreement ("Agreement") is made and
entered into as of December 29, 1997, by and among Queen Sand Resources, Inc., a
Delaware corporation ("Company"), Enron Capital & Trade Resources Corp., a
Delaware corporation, as Agent for the Lenders described below ("Agent"), and,
solely for the purpose of the matters set forth in Section 3.12 hereof, Joint
Energy Development Investments Limited Partnership, a Delaware limited
partnership ("JEDI").

                  This Agreement is made in connection with the Subordinated
Revolving Credit Loan Agreement dated as of December 29, 1997 (as the same may
be amended or supplemented from time to time, "Loan Agreement") among Queen Sand
Resources, Inc., a Nevada corporation ("Borrower"), and the lenders who are or
may become party thereto ("Lenders"), and the Agent. In order to induce the
Lender to enter into the Loan Agreement, the Company has executed a Guaranty and
agreed to provide the registration and other rights set forth in this Agreement.
The execution and delivery of this Agreement is a condition precedent to the
Initial Loans (as defined in the Loan Agreement).

                  The parties agree as follows:

                                    ARTICLE I

                  Section 1.01. Definitions. Capitalized terms used and not
otherwise defined herein which are defined in the Loan Agreement are used herein
as so defined. The terms set forth below are used herein as so defined:

                  "Common Stock" means the common stock, par value $0.0015 per
share, of the Company.

                  "Exchange Shares" means any shares of Common Stock issued
pursuant to Section 2.11 of the Loan Agreement (or any other securities issued
or issuable in respect of such shares of Common Stock pursuant to any dividend,
distribution, recapitalization, merger or consolidation or otherwise) excluding
any such shares which have ceased to be Registrable Securities pursuant to
Section 1.02 hereof.

                  "Exchange Act" means the Securities Exchange Act of 1934, as
amended.

                  "Holder" means the record holder of any Exchange Shares.

                  "Registrable Securities" means, subject to Section 1.02
hereof, the Exchange Shares and any other shares of Common Stock held by a
Holder that have not ceased to be Registrable Securities pursuant to Section
1.02 hereof.

                  "Securities Act" means the Securities Act of 1933, as amended
from time to time, and the rules and regulations of the Commission promulgated
thereunder.
<PAGE>   2
                  "Selling Holder" means a Holder who is selling Registrable
Securities pursuant to a Registration Statement (as defined herein).

                  "Voting Securities" of any Person means capital stock or other
equity interests of such Person which ordinarily is entitled (without regard to
the occurrence of any additional event or contingency) to vote for the election
of directors (or persons performing similar functions) of such Person.

                  Section 1.02. Registrable Securities. Any Registrable Security
will cease to be a Registrable Security when (i) a Registration Statement
covering such Registrable Security has been declared effective by the Commission
and such Registrable Security has been issued, sold or disposed of pursuant to
such effective Registration Statement or (ii) such Registrable Security is
disposed of pursuant to Rule 144 (or any similar provision then in force) under
the Securities Act, (iii) such Registrable Security is eligible to be disposed
of pursuant to paragraph (k) of Rule 144 (or any similar provision then in
force) under the Securities Act or (iv) such Registrable Security is held by the
Company or one of its Subsidiaries.

                                   ARTICLE II

                  Section 2.01. Demand Registration. (a) Any time after the date
of this Agreement, any Holder or Holders who collectively beneficially own at
least a majority of the Exchange Shares outstanding at such time may request (a
"Request Notice") the Company to register under the Securities Act all or any
portion (provided that such portion will have an aggregate offering price of at
least $1,000,000) of the Registrable Securities that are held for sale in the
manner specified in the Request Notice; provided that the Company shall be
obligated to register Registrable Securities pursuant to this Section 2.01 on
one occasion only.

                  (b) Promptly following receipt of a Request Notice, the
Company shall immediately notify any Person who is a Holder (except the Holder
or Holders who gave the Request Notice) of the receipt of a Request Notice and
shall use its best efforts to file a registration statement under the Securities
Act (each such registration statement is hereinafter referred to as a
"Registration Statement") effecting the registration under the Securities Act,
for public sale in accordance with the method of disposition specified in such
Request Notice, the Registrable Securities specified in the Request Notice (and
in any notices received from other Holders no later than the 10th Business Day
after receipt of the notice sent by the Company) (such other Holders and the
Holder or Holders who gave the Request Notice are hereinafter referred to as the
"Requesting Holders"). If such method of disposition shall be an underwritten
public offering, the Company may designate the managing underwriter of such
offering, subject to the approval of the Requesting Holders holding a majority
of the Registrable Securities to be registered, which approval shall not be
withheld unreasonably. A request pursuant to this Section 2.01 shall be counted
only when (i) all the Registrable Securities requested to be included in any
such registration have been so included, (ii) the corresponding Registration
Statement has become effective under the Securities Act, and (iii) the public
offering has been consummated and the Registrable Securities have been sold on
the terms and conditions specified therein. Notwithstanding anything to the
contrary contained herein,



                                        2
<PAGE>   3
the Company may delay the filing or effectiveness of a Registration Statement
after receipt of a Request Notice (i) for up to 90 days if at the time of such
request, the Company is engaged in a firm commitment underwritten public
offering of its securities in which Holders may include Registrable Securities
and for which the Company has delivered the notice to Holders required by the
first sentence of Section 2.02 or (ii) for up to 60 days if at the time of such
request, the Board of Directors of the Company determines in its reasonable
judgment and in good faith that the filing of such a Registration Statement or
the making of any required disclosure in connection therewith would have a
material adverse effect on the Company or substantially interfere with a
significant transaction in which the Company is then engaged; provided that the
Company may not delay the filing of a Registration Statement in reliance on this
clause (ii) more than once during any period of twelve consecutive calendar
months.

                  (c) The Company shall be entitled to include in any
Registration Statement filed pursuant to this Section 2.01, for sale in
accordance with the method of disposition specified by the Requesting Holders,
Voting Securities to be sold by the Company for its own account, except as and
to the extent that, in the opinion of the managing underwriter (if such method
of disposition shall be an underwritten public offering), such inclusion would
materially jeopardize the successful marketing of the Registrable Securities to
be sold. Any Person other than a Holder entitled to piggyback registration
rights with respect to a Registration Statement filed pursuant to this Section
2.01 may include Voting Securities of the Company with respect to which such
rights apply in such Registration Statement for sale in accordance with the
method of disposition specified by the Requesting Holder, except and to the
extent that, in the opinion of the managing underwriter (if such method of
disposition shall be an underwritten public offering) such inclusion would
materially jeopardize the successful marketing of the Registrable Securities to
be sold. Except as provided in this subsection (c), the Company will not effect
any other registration of its Voting Securities (except with respect to
Registration Statements on Form S-4 or S-8 for purposes permissible under such
forms as of the date hereof, or any successor forms for comparable purposes that
may be adopted by the Commission), whether for its own account or that of any
other security holder, from the date of receipt of a Request Notice requesting
the registration of an underwritten public offering until the completion of the
distribution by the underwriters of all securities thereunder.

                  Section 2.02. Piggy-Back Registration. If the Company proposes
to register any equity securities under the Securities Act for sale to the
public for cash, whether for its own account or for the account of other
security holders or both (except with respect to Registration Statements on
Forms S-4 or S-8 for purposes permissible under such forms as of the date
hereof, or any successor forms for comparable purposes that may be adopted by
the Commission), each such time it will give written notice to all Holders of
its intention to do so no less than 15 Business Days prior to the anticipated
filing date. Upon the written request of any Holder, received by the Company no
later than the 10th Business Day after receipt by such Holder of the notice sent
by the Company, to register, on the same terms and conditions as the securities
otherwise being sold pursuant to such registration, any of its Registrable
Securities (which request shall state the intended method of disposition
thereof), the Company will use its best efforts to cause the Registrable
Securities as to which registration shall have been so requested to be included
in the securities to be covered by the Registration Statement proposed to be
filed by the Company, on the same terms and conditions as any similar securities
included therein, all to the extent requisite to permit the sale or other



                                        3
<PAGE>   4
disposition by each Holder (in accordance with its written request) of such
Registrable Securities so registered; provided, however, that the Company may at
any time prior to the effectiveness of any such Registration Statement, in its
sole discretion and without the consent of any Holder, abandon the proposed
offering in which any Holder had requested to participate. The number of
Registrable Securities to be included in such a registration may be reduced or
eliminated if and to the extent, in the case of an underwritten offering, the
managing underwriter shall render to the Company its opinion that such inclusion
would materially jeopardize the successful marketing of the securities
(including the Registrable Securities) proposed to be sold therein; provided,
however, that (a) no Exchange Shares shall be excluded from such registration
unless all other Registrable Securities held by any Holder which are not
Exchange Shares have been excluded from such registration (except to the extent
that such other Registrable Securities may be included in the registration
pursuant to registration rights other than those granted hereunder) and (b) such
number of shares of Registrable Securities shall not be reduced (i) if any
securities included in such registration are included other than for the account
of (x) the Company or (y) persons exercising registration rights granted
pursuant to the agreements listed on Schedule I hereto (as in effect as of the
date hereof) (the "Schedule I Agreements") and (ii) except as provided below,
unless the shares included in the registration pursuant to piggy-back
registration rights granted pursuant to the Schedule I Agreements are also
reduced on a pro rata basis; provided further that, notwithstanding clause (ii)
above, the piggy-back registration rights granted hereby shall be subject to the
prior right of holders of registrable securities under the Registration Rights
Agreement dated May 6, 1997 between the Company and JEDI (the "JEDI Rights
Agreement") to include any or all of such registrable securities before any
Holder includes any or all of its Registrable Securities in any registration
relating to an underwritten public offering with respect to which, in the
opinion of the managing underwriter, the inclusion in the offering of all shares
requested to be registered by all Persons holding registration rights would
materially jeopardize the successful marketing of the securities to be sold.
From and after the date of this Agreement and until no Registrable Securities
remain outstanding, the Company shall not grant any piggy-back registration
rights to any Person unless such rights are expressly made subject to the prior
right of Holders to include any or all of their Registrable Securities before
such other Person includes any shares in any registration relating to an
underwritten public offering with respect to which, in the opinion of the
managing underwriter, the inclusion in the offering of all shares requested to
be registered by all Persons holding registration rights would materially
jeopardize the successful marketing of the securities (including the Registrable
Securities) to be sold. In the event that the number of Registrable Securities
to be included in a registration is to be reduced as provided above, within 10
Business Days after receipt by each Holder proposing to sell Registrable
Securities pursuant to the registered offering of the opinion of such managing
underwriter, all such Selling Holders may allocate among themselves the number
of shares of such Registrable Securities which such opinion states may be
distributed without adversely affecting the distribution of the securities
covered by the Registration Statement, and if such Holders are unable to agree
among themselves with respect to such allocation, such allocation shall be made
in proportion to the respective numbers of shares specified in their respective
written requests. Notwithstanding anything to the contrary contained in this
Section 2.02, in the event that there is a firm underwriting commitment offer of
securities of the Company pursuant to a Registration Statement covering
Registrable Securities and a Person does not elect to sell its Registrable
Securities to the underwriters of the Company's securities in connection with
such offering, such Person shall not offer for sale, sell, grant any option for
the sale of, or otherwise



                                        4
<PAGE>   5
dispose of, directly or indirectly, any shares of Common Stock, or any
securities convertible into or exchangeable into or exercisable for any shares
of Common Stock during the period of distribution of the Company's securities by
such underwriters, which shall be specified in writing by the underwriters,
shall not exceed any period during which management of the Company and others
are similarly prohibited from disposing of shares of Common Stock and shall not
exceed 180 days following the date of effectiveness under the Securities Act of
the Registration Statement relating thereto if the net proceeds to the Company
from such offering will be $25,000,000 or greater and shall not exceed 60 days
following the date of effectiveness under the Securities Act of the Registration
Statement relating thereto if the net proceeds to the Company from such offering
will be less than $25,000,000.

         Section 2.03. Registration Procedures. If and whenever the Company is
required pursuant to this Agreement to effect the registration of any of the
Registrable Securities under the Securities Act, the Company will, as
expeditiously as possible:

                  (a) prepare and file as promptly as possible with the
         Commission a Registration Statement, on a form available to the
         Company, with respect to such securities (which filing shall be made
         within 45 days after the receipt by the Company of a Request Notice)
         and use its best efforts to cause such Registration Statement to become
         and remain effective for the period of the distribution contemplated
         thereby (determined pursuant to subparagraph (g) below);

                  (b) prepare and file with the Commission such amendments and
         supplements to such Registration Statement and the prospectus used in
         connection therewith as may be necessary to keep such Registration
         Statement effective for the period specified in subsection (g) below
         and as may be necessary to comply with the provisions of the Securities
         Act with respect to the disposition of all securities covered by such
         Registration Statement in accordance with the sellers' intended method
         of disposition set forth in such Registration Statement for such
         period;

                  (c) furnish to each Selling Holder and to each underwriter
         such number of copies of the Registration Statement and the prospectus
         included therein (including each preliminary prospectus and each
         document incorporated by reference therein to the extent then required
         by the rules and regulations of the Commission) as such Persons may
         reasonably request in order to facilitate the public sale or other
         disposition of the Registrable Securities covered by such Registration
         Statement;

                  (d) use its best efforts to register or qualify the
         Registrable Securities covered by such Registration Statement under the
         securities or blue sky laws of such jurisdictions as the Selling
         Holders or, in the case of an underwritten public offering, the
         managing underwriter, shall reasonably request, provided, however, that
         the Company will not be required to subject itself to taxation in any
         such jurisdiction or to consent to general service of process in any
         such jurisdiction;



                                        5
<PAGE>   6
                  (e) immediately notify each Selling Holder and each
         underwriter, at any time when a prospectus relating thereto is required
         to be delivered under the Securities Act, of the happening of any event
         as a result of which the prospectus contained in such Registration
         Statement, as then in effect, includes an untrue statement of a
         material fact or omits to state any material fact required to be stated
         therein or necessary to make the statements therein not misleading in
         the light of the circumstances then existing and as promptly as
         practicable amend the Registration Statement or supplement the
         prospectus or take other appropriate action so that the prospectus does
         not include an untrue statement of a material fact or omit to state a
         material fact required to be stated therein or necessary to make the
         statements therein not misleading in the light of the circumstances
         then existing; provided, however, that, in the case of a shelf
         registration, the Company, on one occasion during each such
         registration, may delay taking such action for a period of 45 days,
         during which time the Selling Holders shall not sell any Registrable
         Securities, if the Board of Directors determines in its reasonable
         judgment and in good faith that the making of any required disclosure
         in connection therewith would have a material adverse effect on the
         Company or substantially interfere with a significant transaction in
         which the Company is then engaged;

                  (f) in the case of an underwritten public offering, furnish,
         (i) on the date that Registrable Securities are delivered to the
         underwriters for sale pursuant to such Registration Statement, an
         opinion of counsel for the Company dated as of such date and addressed
         to the underwriters and to the Selling Holders, stating that such
         Registration Statement has become effective under the Securities Act
         and that (A) to the best knowledge of such counsel, no stop order
         suspending the effectiveness thereof has been issued and no proceedings
         for that purpose have been instituted or are pending or contemplated
         under the Securities Act, (B) the Registration Statement, the related
         prospectus, and each amendment or supplement thereof, comply as to form
         in all material respects with the requirements of the Securities Act
         and the applicable rules and regulations thereunder of the Commission
         (except that such counsel need express no opinion as to the financial
         statements or any engineering report contained or incorporated therein)
         and (C) to such other effects as may reasonably be requested by counsel
         for the underwriters, and (ii) on the effective date of the
         Registration Statement and on the date that Registrable Securities are
         delivered to the underwriters for sale pursuant to such Registration
         Statement, a letter dated such dates from the independent accountants

         schedules thereto that are included or incorporated by reference in the
         Registration Statement or the prospectus, or any amendment or
         supplement thereof, comply as to form in all material respects with the
         applicable requirements of the Securities Act and the published rules
         and regulations thereunder, and such letter shall additionally address

         to such Registration Statement, and any attorney, accountant or other
         agent retained by such representative of the Selling Holders or
         underwriter (the "Inspectors"), all financial and other records,
         pertinent corporate documents and properties of the Company, and cause
         the Company's officers, directors and employees to supply all
         information reasonably requested by any such Inspector in connection
         with such Registration Statement. For purposes of subsections (a) and
         (b) above and of Section 2.01(c) of this Agreement, the period of
         distribution of Registrable Securities in a firm commitment
         underwritten public offering shall be deemed to extend until each
         underwriter has completed the distribution of all securities purchased
         by it, and the period of distribution of Registrable Securities in any
         other registration shall be deemed to extend until the earlier of the
         sale of all Registrable Securities covered thereby or one year,
         excluding any period of time during which Selling Holders are
         prohibited from selling Registrable Securities pursuant to Section 2.02
         or Section 2.03(e);

                  (h) use its best efforts to keep effective and maintain for
         the period specified in subparagraph (g) a registration, qualification,
         approval or listing obtained to cover the Registrable Securities as may
         be necessary for the Selling Holders to dispose thereof and shall from
         time to time amend or supplement any prospectus used in connection
         therewith to the extent necessary in order to comply with applicable
         law;

                  (i) use its best efforts to cause the Registrable Securities
         to be registered with or approved by such other governmental agencies
         or authorities as may be necessary by virtue of the business and
         operations of the Company to enable the Selling Holders to consummate
         the disposition of such Registrable Securities; and

                  (j) enter into customary agreements (including, if requested,
         an underwriting agreement in customary form) and take such other
         actions as are reasonably requested by the Selling Holders or the
         underwriters, if any, in order to expedite or facilitate the
         disposition of such Registrable Securities.

         In connection with each registration hereunder, each Selling Holder
will furnish promptly to the Company in writing such information with respect to
itself and the proposed distribution by it as shall be reasonably necessary in
order to ensure compliance with federal and applicable state securities laws.

         In connection with each registration hereunder with respect to an
underwritten public offering, the Company and each Selling Holder agrees to
enter into a written agreement with the managing underwriter or underwriters
selected in the manner herein provided in such form and containing such
provisions as are customary in the securities business for such an arrangement
between underwriters and companies of the Company's size and investment stature,
provided that such agreement shall not contain any such provision applicable to
the Company or the Selling Holders that is inconsistent with the provisions
hereof; and further provided, that the time and place of the closing under said
agreement shall be as mutually agreed upon among the Company, the Selling
Holders and such managing underwriter.

                  Section 2.04. Expenses. (a) All expenses incident to the
Company's performance under or compliance with this Agreement, including without
limitation, all registration and filing fees, blue sky fees and expenses,
printing expenses, listing fees, fees and disbursements of counsel and
independent public accountants for the Company, fees of the National Association
of Securities Dealers, Inc., transfer taxes, fees of transfer agents and
registrars and costs of insurance and reasonable out-of-pocket expenses
(including, without limitation, legal fees of one counsel for all Selling
Holders) of the Selling Holders, but excluding any Selling Expenses (as defined
below), are herein called "Registration Expenses." All underwriting fees,
discounts and selling commissions allocable to the sale of the Registrable
Securities are herein called "Selling Expenses."

                  (b) The Company will pay all Registration Expenses in
connection with each Registration Statement filed pursuant to this Agreement,
whether or not the Registration Statement becomes effective, and the Selling
Holders shall pay Selling Expenses in connection with any Registrable Securities
registered pursuant to this Agreement.

                  Section 2.05. Indemnification. (a) In the event of a
registration of any Registrable Securities under the Securities Act pursuant to
this Agreement, the Company will indemnify and hold harmless each Selling Holder
thereunder and each underwriter of Registrable Securities thereunder and each
Person, if any, who controls such Selling Holder or underwriter within the
meaning of the Securities Act and the Exchange Act, against any losses, claims,
damages or liabilities (including reasonable attorneys' fees) ("Losses"), joint
or several, to which such Selling Holder or underwriter or controlling Person
may become subject under the Securities Act, the Exchange Act or otherwise,
insofar as such Losses, (or actions in respect thereof) arise out of or are
based upon any untrue statement or alleged untrue statement of any material fact
contained in any Registration Statement under which such Registrable Securities
were registered under the Securities Act pursuant to this Agreement, any
preliminary prospectus or final prospectus contained therein, or any amendment
or supplement thereof, or arise out of or are based upon the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, and will reimburse each
such Selling Holder, each such underwriter and each such controlling Person for
any legal or other expenses reasonably incurred by them in connection with
investigating or defending any such Loss or actions; provided, however, that the
Company will not be liable in any such case if and to the extent that any such
loss, claim, damage or liability arises out of or is based upon an untrue
statement or alleged untrue statement or omission or alleged omission so made in
conformity with information furnished by such Selling Holder, such underwriter
or such controlling Person in writing specifically for use in such Registration
Statement or prospectus.

                  (b) Each Selling Holder agrees to indemnify and hold harmless
the Company, its directors, officers, employees and agents and each Person, if
any, who controls the Company within the meaning of the Securities Act or of the
Exchange Act to the same extent as the foregoing indemnity from the Company to
such Selling Holder, but only with respect to information regarding such Selling
Holder furnished in writing by or on behalf of such Selling Holder expressly for
inclusion in any Registration Statement or prospectus relating to the
Registrable Securities, or any amendment or supplement thereto; provided,
however, that the liability of such Selling Holder shall not be greater in
amount than the dollar amount of the proceeds (net of any Selling Expenses)



                                        8

received by such Selling Holder from the sale of the Registrable Securities
giving rise to such indemnification.

                  (c) Promptly after receipt by an indemnified party hereunder
of notice of the commencement of any action, such indemnified party shall, if a
claim in respect thereof is to be made against the indemnifying party hereunder,
notify the indemnifying party in writing thereof, but the omission so to notify
the indemnifying party shall not relieve it from any liability which it may have
to any indemnified party other than under this Section 2.05. In case any such
action shall be brought against any indemnified party and it shall notify the
indemnifying party of the commencement thereof, the indemnifying party shall be
entitled to participate in and, to the extent it shall wish, to assume and
undertake the defense thereof with counsel reasonably satisfactory to such
indemnified party and, after notice from the indemnifying party to such
indemnified party of its election so to assume and undertake the defense
thereof, the indemnifying party shall not be liable to such indemnified party
under this Section 2.05 for any legal expenses subsequently incurred by such
indemnified party in connection with the defense thereof other than reasonable
costs of investigation and of liaison with counsel so selected; provided,
however, that, (i) if the indemnifying party has failed to assume the defense
and employ counsel or (ii) if the defendants in any such action include both the
indemnified party and the indemnifying party and counsel to the indemnified
party shall have concluded that there may be reasonable defenses available to
the indemnified party that are different from or additional to those available
to the indemnifying party or if the interests of the indemnified party
reasonably may be deemed to conflict with the interests of the indemnifying
party, then the indemnified party shall have the right to select a separate
counsel and to assume such legal defense and otherwise to participate in the
defense of such action, with the expenses and fees of such separate counsel and
other expenses related to such participation to be reimbursed by the
indemnifying party as incurred, provided that such fees and expenses shall be
reimbursed for only one counsel for all indemnified parties.

                  (d) If the indemnification provided for in this Section 2.05
is available to the Company or the Selling Holders or is insufficient to hold
them harmless in respect of any losses, claims, damages, liabilities or expenses
referred to herein, then each such indemnifying party, in lieu of indemnifying
such indemnified party, shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages, liabilities and
expenses as between the Company on the one hand and each Selling Holder on the
other, in such proportion as is appropriate to reflect the relative fault of the
Company on the one hand and of each Selling Holder on the other in connection
with the statements or omissions which resulted in such losses, claims, damages
or liabilities, as well as any other relevant equitable considerations. The
relative fault of the Company on the one hand and each Selling Holder on the
other shall be determined by reference to, among other things, whether the
untrue or alleged untrue statements of a material fact or the omission or
alleged omission to state a material fact has been made by, or relates to,
information supplied by such party, and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or
omission.

                  No person of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Securities Act) shall be entitled to contribution from
any Person who is not guilty of such fraudulent misrepresentation.
